          SECTION 104.  Acts of Holders.  (a) Any request, demand,
                        ---------------                           
authorization, direction, notice, consent, waiver or other action provided by
this Indenture to be given or taken by Holders of the Outstanding Securities of
all series or one or more series, as the case may be, may be embodied in and
evidenced by one or more instruments of substantially similar tenor signed by
such Holders in person or by agents duly appointed in writing.  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.  Such instrument or instruments (and the
action embodied therein and evidenced thereby) are herein sometimes referred to
as the "Act" of the Holders signing such instrument or instruments.  Proof of
execution of any such instrument or of a writing appointing any such agent, or
of the holding by any Person of a Security, shall be sufficient for any purpose
of this Indenture and (subject to Section 602) conclusive in favor of the
Trustee and the Company and any agent of the Trustee or 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 of such
execution or by a certificate of a 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 a signer acting in a capacity other than his individual
capacity, such certificate or affidavit shall also constitute sufficient proof
of his authority.  The fact and date of the execution of any such instrument or
writing, or the authority of the Person executing the same, may also be proved
in any other reasonable manner which the Trustee deems sufficient.  Subject to
Article Six, the execution of any instrument by a Holder or his agent may be
proved in accordance with such reasonable rules and regulations as may be
prescribed by the Trustee or in such manner as shall be satisfactory to the
Trustee.
          (c)      The ownership of Registered Securities shall be proved by the
Security Register.

          (d)      The ownership of Bearer Securities may be proved by the
production of such Bearer Securities or by a certificate executed, as
depositary, by any trust company, bank, banker or other depositary, wherever
situated, if such certificate shall be deemed by the Trustee to be satisfactory,
showing that at the date therein mentioned such Person had on deposit with such
depositary, or exhibited to it, the Bearer Securities therein described; or such
facts may be proved by the certificate or affidavit of the Person holding such
Bearer Securities, if such certificate or affidavit is deemed by the Trustee to
be satisfactory. The Trustee and the Company may assume that such ownership of
any Bearer Security continues until (1) another certificate or affidavit bearing
a later date issued in respect of the same Bearer Security is produced, or (2)
such Bearer Security is produced to the Trustee by some other Person, or (3)
such Bearer Security is surrendered in exchange for a Registered Security, or
(4) such Bearer Security is no longer Outstanding. The ownership of Bearer
Securities may also be proved in any other manner which the Trustee deems
sufficient.

          (e)      If the Company shall solicit from the Holders of Registered
Securities any request, demand, authorization, direction, notice, consent,
waiver or other Act, the Company may, at its option, in or pursuant to a 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 Act, but the Company shall have no obligation to do so.
Notwithstanding TIA Section 316(c), such record date shall be the record date
specified in or pursuant to such Board Resolution, which shall be a date not
earlier than the date 30 days prior to the first solicitation of Holders
generally in connection therewith and not later than the date such solicitation
is completed.  If such a record date is fixed, such request, demand,
authorization, direction, notice, consent, waiver or other Act may be given
before or after such record date, but only the Holders of record at the close of
business on such record date shall be deemed to be Holders for the purposes of
determining whether Holders of the requisite proportion of Outstanding
Securities have authorized or agreed or consented to such re- 

                                     -12-

 
quest, demand, authorization, direction, notice, consent, waiver or other Act,
and for that purpose the Outstanding Securities shall be computed as of such
record date; provided that no such authorization, agreement or consent by the
             --------
Holders on such record date shall be deemed effective unless it shall become
effective pursuant to the provisions of this Indenture not later than eleven
months after the record date.

          (f)      Any request, demand, authorization, direction, notice,
consent, waiver or other Act of the Holder of any Security shall bind every
future Holder of the same Security and 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, omitted or suffered to be done by the Trustee, any
Security Registrar, any Paying Agent, any Authenticating Agent or the Company in
reliance thereon, whether or not notation of such action is made upon such
Security.

          SECTION 105.  Notices, etc., to Trustee and Company.  Any request,
                        -------------------------------------               
demand, authorization, direction, notice, consent, waiver or Act of Holders or
other document provided or permitted by this Indenture to be made upon, given or
furnished to, or filed with,
          
          (1)      the Trustee by any Holder or by the Company shall be
sufficient for every purpose hereunder if made, given, furnished or filed in
writing to or with the Trustee at its Corporate Trust Office, or

          (2)      the Company by the Trustee or by any Holder shall be
sufficient for every purpose hereunder (unless otherwise herein expressly
provided) 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 Indenture or at any other address previously furnished in
writing to the Trustee by the Company.

          SECTION 106.  Notice to Holders;  Waiver.  Where this Indenture
                        --------------------------                       
provides for notice of any event to Holders of Registered Securities by the
Company or the Trustee, such notice shall be sufficiently given (unless
otherwise herein expressly provided) if in writing and mailed, first-class
postage prepaid, to each such Holder 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 Holders of Registered Securities is given by mail,
neither the failure to mail such notice, nor any defect in any notice so mailed,
to any particular Holder shall affect the sufficiency of such notice with
respect to other Holders of Registered Securities or the sufficiency of any
notice to Holders of Bearer Securities given as provided herein.  Any notice
mailed to a Holder in the manner herein prescribed shall be conclusively deemed
to have been received by such Holder, whether or not such Holder actually
receives such notice.

          If by reason of the suspension of or irregularities in regular mail
service or by reason of any other cause it shall be impracticable to give such
notice by mail, then such notification to Holders of Registered Securities as
shall be made with the approval of the Trustee shall constitute a sufficient
notification to such Holders for every purpose hereunder.

          Except as otherwise expressly provided herein or otherwise specified
with respect to any Securities pursuant to Section 301, where this Indenture
provides for notice to Holders of Bearer Securities of any event, such notice
shall be sufficiently given if published in an Authorized Newspaper in The City
of New York and in such other city or cities as may be specified in such
Securities on a Business Day, such publication to be not later than the latest
date, and not earlier than the earliest date, prescribed for the giving of such
notice.  Any such notice shall be deemed to have been given on the date of such
publication or, if published more than once, on the date of the first such
publication.

          If by reason of the suspension of publication of any Authorized
Newspaper or Authorized Newspapers or by reason of any other cause it shall be
impracticable to publish any no- 

                                     -13-

 
tice to Holders of Bearer Securities as provided above, then such notification
to Holders of Bearer Securities as shall be given with the approval of the
Trustee shall constitute sufficient notice to such Holders for every purpose
hereunder. Neither the failure to give notice by publication to any particular
Holder of Bearer Securities as provided above, nor any defect in any notice so
published, shall affect the sufficiency of such notice with respect to other
Holders of Bearer Securities or the sufficiency of any notice to Holders of
Registered Securities given as provided herein.

          Any request, demand, authorization, direction, notice, consent or
waiver required or permitted under this Indenture shall be in the English
language, except that any published notice may be in an official language of the
country of publication.

          Where this Indenture provides for notice in any manner, such notice
may be waived in writing by the Person entitled to receive such notice, either
before or after the event, and such waiver shall be the equivalent of such
notice.  Waivers of notice by Holders shall be filed with the Trustee, but such
filing shall not be a condition precedent to the validity of any action taken in
reliance upon such waiver.

Authenticating Agent and their successors hereunder and the Holders any benefit
or any legal or equitable right, remedy or claim under this Indenture.

          SECTION 111.  No Personal Liability.   No recourse under or upon any

          SECTION 201. Forms of Securities. The Registered Securities, if any,
                       -------------------
of each series and the Bearer Securities, if any, of each series and related
coupons shall be in substantially the forms as shall be established in one or
more indentures supplemental hereto or approved from time to time by or pursuant
to a Board Resolution in accordance with this Indenture, shall have such
appropriate insertions, omissions, substitutions and other variations as are
required or permitted by this Indenture or any indenture supplemental hereto,
and may have such letters, numbers or other marks of identification or
designation and such legends or endorsements placed thereon as the Company may
deem appropriate and as are not inconsistent with the provisions of this
Indenture, or as may be required to comply with any law or with any rule or
regulation made pursuant thereto or with any rule or regulation of any stock
exchange on which the Securities may be listed, or to conform to usage.

          Unless otherwise specified as contemplated by Section 301, Bearer
Securities shall have interest coupons attached.

          The definitive Securities and coupons shall be printed, lithographed
or engraved or produced by any combination of these methods on a steel engraved
border or steel engraved borders or may be produced in any other manner, all as
determined by the officers executing such Securities or coupons, as evidenced by
their execution of such Securities or coupons.

          SECTION 202.  Form of Trustee's Certificate of Authentication. Subject
                        -----------------------------------------------         
to Section 611, the Trustee's certificate of authentication shall be in
substantially the following form:

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

                                   [BANK], as Trustee
          
                                    By: 
                                       -------------------------------------
                                           Authorized Signatory

          SECTION 203.  Securities Issuable in Global Form.  If Securities of or
                        ----------------------------------                      
within a series are issuable in global form, as specified as contemplated by
Section 301, then, notwithstanding clause (8) of Section 301 and the provisions
of Section 302, any such Security shall represent such of the Outstanding
Securities of such series as shall be specified therein and may provide that it
shall represent the aggregate amount of Outstanding Securities of such series
from time to time endorsed thereon and that the aggregate amount of Outstanding
Securities of such series represented thereby may from time to time be increased
or decreased to reflect exchanges.  Any endorsement of a Security in global
form to reflect the amount, or any increase or decrease in the amount, of
Outstanding Securities represented thereby shall be made by the Trustee in such
manner and upon instructions given by such Person or Persons as shall be
specified therein or in the Company Order to be delivered to the Trustee
pursuant to Section 303 or 304.  Subject to the provisions of Section 303 and,
if applicable, Section 304, the Trustee shall deliver and redeliver any Security

specified therein or in the applicable Company Order. If a Company Order
pursuant to Section 303 or 304 has been, or simultaneously is, delivered, any
instructions by the Company with respect to endorsement or delivery or
redelivery of a Security in global form shall be in writing but need not comply
with Section 102 and need not be accompanied by an Opinion of Counsel.

          The provisions of the last sentence of Section 303 shall apply to any
Security represented by a Security in global form if such Security was never
issued and sold by the Company and the Company delivers to the Trustee the
Security in global form together with written instructions (which need not
comply with Section 102 and need not be accompanied by an Opinion of Counsel)
with regard to the reduction in the principal amount of Securities represented
thereby, together with the written statement contemplated by the last sentence
of Section 303.

          Notwithstanding the provisions of Section 307, unless otherwise
specified as contemplated by Section 301, payment of principal of (and premium,
if any) and interest on any Security in permanent global form shall be made to
the Person or Persons specified therein.

          Notwithstanding the provisions of Section 308 and except as provided
in the preceding  paragraph, the Company, the Trustee and any agent of the
Company and the Trustee shall treat as the Holder of such principal amount of
Outstanding Securities represented by a permanent global Security (i) in the
case of a permanent global Security in registered form, the Holder of such
permanent global Security in registered form, or (ii) in the case of a
permanent global Security in bearer form, Euroclear or CEDEL.

the case of Registered Securities, as to denomination and except as may
otherwise be provided in or pursuant to such Board Resolution (subject to
Section 303) and set forth in such Officers' Certificate or in any such
indenture supplemental hereto.  All Securities of any one series need not be
issued at the same time and, unless otherwise provided, a series may be
reopened, without the consent of the Holders, for issuances of additional

          SECTION 302.  Denominations.   The Securities of each series shall be

issuable in such denominations as shall be specified as contemplated by Section
301.  With respect to Securities of any series denominated in Dollars, in the
absence of any such provisions with respect to the Securities of any series,
the Registered Securities of such series, other than Registered Securities
issued in global form (which may be of any denomination), shall be issuable in
denominations of $1,000 and any integral multiple thereof and the Bearer
Securities of such series, other than Bearer Securities issued in global form
(which may be of any denomination), shall be issuable in a denomination of
$5,000.

          SECTION 303.  Execution, Authentication, Delivery and Dating.  The
                        ----------------------------------------------      
Securities and any coupons appertaining thereto shall be executed by the
Company's Chairman of the Board, its President or one of its Senior Vice
Presidents, and its Chief Financial Officer.  The signature of any of these
officers on the Securities and coupons may be manual or facsimile signatures of
the present or any future such authorized officer and may be imprinted or
otherwise reproduced on the Securities.

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

          At any time and from time to time after the execution and delivery of
this Indenture, the Company may deliver Securities of any series, together with
any coupon appertaining thereto, executed by the Company to the Trustee for
authentication, together with a Company Order for the authentication and
delivery of such Securities, and the Trustee in accordance with the Company 
Order shall authenticate and deliver such Securities; provided, however, that,
                                                      -----------------
in connection with its original issuance, no Bearer Security shall be mailed or
otherwise delivered to any location in the United States; and provided further
                                                              ----------------
that, unless otherwise specified with respect to any series of Securities
pursuant to Section 301, a Bearer Security may be delivered in connection with
its original issuance only if the Person entitled to receive such Bearer
Security shall have furnished a certificate to Euroclear or CEDEL, as the case
may be, in the form set forth in Exhibit A-1 to this Indenture or such other
certificate as may be specified with respect to any series of Securities
pursuant to Section 301, dated no earlier than 15 days prior to the earlier of
the date on which such Bearer Security is delivered and the date on which any
temporary Security first becomes exchangeable for such Bearer Security in
accordance with the terms of such temporary Security and this Indenture. If any
Security shall be represented by a permanent global Bearer Security, then, for
purposes of this Section and Section 304, the notation of a beneficial owner's
interest therein upon original issuance of such

                                      -19-

 
Security or upon exchange of a portion of a temporary global Security shall be
deemed to be delivery in connection with its original issuance of such
beneficial owner's interest in such permanent global Security. Except as
permitted by Section 306, the Trustee shall not authenticate and deliver any
Bearer Security unless all appurtenant coupons for interest then matured have
been detached and canceled.

          If all the Securities of any series are not to be issued at one time
and if the Board Resolution or supplemental indenture establishing such series
shall so permit, such Company Order may set forth procedures acceptable to the
Trustee for the issuance of such Securities and determining the terms of
particular Securities of such series, such as interest rate or formula, maturity
date, date of issuance and date from which interest shall accrue.  In
authenticating such Securities, and accepting the additional responsibilities
under this Indenture in relation to such Securities, the Trustee shall be
entitled to receive, and (subject to TIA Section 315(a) through 315(d)) shall be
fully protected in relying upon,

          (i) an Opinion of Counsel stating that

              (a) the form or forms of such Securities and any coupons have been
established in conformity with the provisions of this Indenture;

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

              (c) such Securities, together with any coupons appertaining
thereto, when completed by appropriate insertions and executed and delivered by
the Company to the Trustee for authentication in accordance with this
Indenture, authenticated and delivered by the Trustee in accordance with this
Indenture and issued by the Company in the manner and subject to any conditions
specified in such Opinion of Counsel, will constitute legal, valid and binding
obligations of the Company, enforceable in accordance with their terms, subject
to applicable bankruptcy, insolvency, reorganization and other similar laws of
general applicability relating to or affecting the enforcement of creditors'
rights generally and to general equitable principles; and

          (ii) an Officers' Certificate stating that all conditions precedent
provided for in this Indenture relating to the issuance of the Securities have
been complied with and that, to the best of the knowledge of the signers of such
certificate, that no Event of Default with respect to any of the Securities
shall have occurred and be continuing.

          If such form or terms have been so established, the Trustee shall not
be required to authenticate such Securities if the issue of such Securities
pursuant to this Indenture will affect the Trustee's own rights, duties,
obligations or immunities under the Securities and this Indenture or otherwise
in a manner which is not reasonably acceptable to the Trustee.

          Notwithstanding the provisions of Section 301 and of the preceding
paragraph, if all the Securities of any series are not to be issued at one time,
it shall not be necessary to deliver an Officers' Certificate otherwise required
pursuant to Section 301 or a Company Order, or an Opinion of Counsel or an
Officers' Certificate otherwise required pursuant to the preceding paragraph at
the time of issuance of each Security of such series, but such order, opinion
and certificates, with appropriate modifications to cover such future
issuances, shall be delivered at or before the time of issuance of the first
Security of such series.

          Each Registered Security shall be dated the date of its authentication
and each Bearer Security shall be dated as of the date specified as contemplated
by Section 301.

                                      -20-

 
          No Security or coupon shall be entitled to any benefit under this
Indenture or be valid or obligatory for any purpose unless there appears on such
Security or Security to which such coupon appertains a certificate of
authentication substantially in the form provided for herein duly executed by
the Trustee by manual signature of an authorized signatory, and such certificate
upon any Security shall be conclusive evidence, and the only evidence, that such
Security has been duly authenticated and delivered hereunder and is entitled to
the benefits of this Indenture.  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 309 together with a written statement (which
need not comply with Section 102 and need not be accompanied by an Opinion of
Counsel) stating that such Security has never been issued and sold by the
Company, 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 304.  Temporary Securities.  (a) Pending the preparation of
                        --------------------                                 
definitive Securities of any series, the Company may execute, and upon 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, in registered form, or, if
authorized, in bearer form with one or more coupons or without coupons, and with
such appropriate insertions, omissions, substitutions and other variations as
the officers executing such Securities may determine, as conclusively evidenced
by their execution of such Securities.  In the case of Securities of any series,
such temporary Securities may be in global form.

          Except in the case of temporary Securities in global form (which shall
be exchanged in accordance with Section 304(b) or as otherwise provided in or
pursuant to a Board Resolution), if temporary Securities of any series are
issued, the Company will cause definitive Securities of that series to be
prepared without unreasonable delay.  After the preparation of definitive
securities of such series, 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 for that series, without charge to the Holder.  Upon surrender
for cancellation of any one or more temporary Securities of any series
(accompanied by any non-matured coupons appertaining thereto), the Company shall
execute and the Trustee shall authenticate and deliver in exchange therefor a
like principal amount of definitive Securities of the same series of authorized
denominations; provided, however, that no definitive Bearer Security shall be
               -----------------                                             
delivered in exchange for a temporary Registered Security; and provided further
                                                               ----------------
that a definitive Bearer Security shall be delivered in exchange for a
temporary Bearer Security only in compliance with the conditions set forth in
Section 303.  Until so exchanged, the temporary Securities of any series shall
in all respects be entitled to the same benefits under this Indenture as
definitive Securities of such series.

          (b) Unless otherwise provided in or pursuant to a Board Resolution,
this Section 304(b) shall govern the exchange of temporary Securities issued in
global form other than through the facilities of The Depository Trust Company.
If any such temporary Security is issued in global form, then such temporary
global Security shall, unless otherwise provided therein, be delivered to the
London office of a depositary or common depositary (the "Common Depositary"),
for the benefit of Euroclear and CEDEL, for credit to the respective accounts of
the beneficial owners of such Securities (or to such other accounts as they may
direct).

          Without unnecessary delay but in any event not later than the date
specified in, or determined pursuant to the terms of, any such temporary global
Security (the "Exchange Date"), the Company shall deliver to the Trustee
definitive Securities, in aggregate principal amount equal to the principal
amount of such temporary global Security, executed by the Company.  On or after
the Exchange Date, such temporary global Security shall be surrendered by the
Common Depositary to the 

                                      -21-

 
to the Trustee, as the Company's agent for such purpose, to be exchanged, in
whole or from time to time in part, for definitive Securities without charge,
and the Trustee shall authenticate and deliver, in exchange for each portion of
such temporary global Security, an equal aggregate principal amount of
definitive Securities of the same series of authorized denominations and of like
tenor as the portion of such temporary global Security to be exchanged. The
definitive Securities to be delivered in exchange for any such temporary global
Security shall be in bearer form, registered form, permanent global bearer form
or permanent global registered form, or any combination thereof, as specified as
contemplated by Section 301, and, if any combination thereof is so specified, as
requested by the beneficial owner thereof; provided, however, that, unless
                                           -----------------
otherwise specified in such temporary global Security, upon such presentation by
the Common Depositary, such temporary global Security is accompanied by a
certificate dated the Exchange Date or a subsequent date and signed by Euro-
clear as to the portion of such temporary global Security held for its account
then to be exchanged and a certificate dated the Exchange Date or a subsequent
date and signed by CEDEL as to the portion of such temporary global Security
held for its account then to be exchanged, each in the form set forth in Exhibit
A-2 to this Indenture or in such other form as may be established pursuant to
Section 301; and provided further that definitive Bearer Securities shall be
                 ----------------
delivered in exchange for a portion of a temporary global Security only in
compliance with the requirements of Section 303.

          Unless otherwise specified in such temporary global Security, the
interest of a beneficial owner of Securities of a series in a temporary global
Security shall be exchanged for definitive Securities of the same series and of
like tenor following the Exchange Date when the account holder instructs
Euroclear or CEDEL, as the case may be, to request such exchange on his behalf
and delivers to Euroclear or CEDEL, as the case may be, a certificate in the
form set forth in Exhibit A-1 to this Indenture (or in such other form as may be
established pursuant to Section 301), dated no earlier than 15 days prior to
the Exchange Date, copies of which certificate shall be available from the
offices of Euroclear and CEDEL, the Trustee, any Authenticating Agent appointed
for such series of Securities and each Paying Agent.  Unless otherwise specified
in such temporary global Security, any such exchange shall be made free of
charge to the beneficial owners of such temporary global Security, except that
a Person receiving definitive Securities must bear the cost of insurance,
postage, transportation and the like unless such Person takes delivery of such
definitive Securities in person at the offices of Euroclear or CEDEL.
Definitive Securities in bearer form to be delivered in exchange for any
portion of a temporary global Security shall be delivered only outside the
United States.

          Until exchanged in full as hereinabove provided, the temporary
Securities of any series shall in all respects be entitled to the same benefits
under this Indenture as definitive Securities of the same series and of like
tenor authenticated and delivered hereunder, except that, unless otherwise
specified as contemplated by Section 301, interest payable on a temporary global
Security on an Interest Payment Date for Securities of such series occurring
prior to the applicable Exchange Date shall be payable to Euroclear and CEDEL on
such Interest Payment Date upon delivery by Euroclear and CEDEL to the Trustee
of a certificate or certificates in the form set forth in Exhibit A-2 to this
Indenture (or in such other forms as may be established pursuant to Section
301), for credit without further interest on or after such Interest Payment Date
to the respective accounts of Persons who are the beneficial owners of such
temporary global Security on such Interest Payment Date and who have each
delivered to Euroclear or CEDEL, as the case may be, a certificate dated no
earlier than 15 days prior to the Interest Payment Date occurring prior to such
Exchange Date in the form set forth as Exhibit A-1 to this Indenture (or in such
other forms as may be established pursuant to Section 301).  Notwithstanding
anything to the contrary herein contained, the certifications made pursuant to
this paragraph shall satisfy the certification requirements of the preceding two
paragraphs of this Section 304(b) and of the third paragraph of Section 303 of
this Indenture and the interests of the Persons who are the beneficial owners
of the temporary global Security with respect to which such certification was
made will be exchanged for definitive Securities of the same series and of like
tenor on the Exchange Date or the date of certification if such date occurs
after the Exchange Date, without further act or deed by such beneficial owners.
Except as otherwise provided in this 


                                     -22-

 
paragraph, no payments of principal or interest owing with respect to a
beneficial interest in a temporary global Security will be made unless and
until such interest in such temporary global Security shall have been exchanged
for an interest in a definitive Security. Any interest so received by Euroclear
and CEDEL and not paid as herein provided shall be returned to the Trustee prior
to the expiration of two years after such Interest Payment Date in order to be
repaid to the Company.

          SECTION 305.  Registration, Registration of Transfer and Exchange. The
                        ---------------------------------------------------     
Company shall cause to be kept at the Corporate Trust Office of the Trustee or
in any office or agency of the Company in a Place of Payment a register for each
series of Securities (the registers maintained in such office or in any such
office or agency of the Company in a Place of Payment being herein sometimes
referred to collectively as the "Security Register") in which, subject to such
reasonable regulations as it may prescribe, the Company shall provide for the
registration of Registered Securities and of transfers of Registered Securities.
The Security Register shall be in written form or any other form capable of
being converted into written form within a reasonable time.  The Trustee, at its
Corporate Trust Office, is hereby initially appointed "Security Registrar" for
the purpose of registering Registered Securities and transfers of Registered
Securities on such Security Register as herein provided.  In the event that the
Trustee shall cease to be Security Registrar, it shall have the right to examine
the Security Register at all reasonable times.

          Subject to the provisions of this Section 305, upon surrender for
registration of transfer of any Registered Security of any series at any office
or agency of the Company in a Place of Payment for that series, the Company
shall execute, and the Trustee shall authenticate and deliver, in the name of
the designated transferee or transferees, one or more new Registered Securities
of the same series, of any authorized denominations and of a like aggregate
principal amount, bearing a number not contemporaneously outstanding, and
containing identical terms and provisions.

          Subject to the provisions of this Section 305, at the option of the
Holder, Registered Securities of any series may be exchanged for other
Registered Securities of the same series, of any authorized denomination or
denominations and of a like aggregate principal amount, containing identical
terms and provisions, upon surrender of the Registered Securities to be
exchanged at any such office or agency.  Whenever any such Registered Securities
are so surrendered for exchange, the Company shall execute, and the Trustee
shall authenticate and deliver, the Registered Securities which the Holder
making the exchange is entitled to receive.  Unless otherwise specified with
respect to any series of Securities as contemplated by Section 301, Bearer
Securities may not be issued in exchange for Registered Securities.

          If (but only if) permitted by the applicable Board Resolution and
(subject to Section 303) set forth in the applicable Officers' Certificate, or
in any indenture supplemental hereto, delivered as contemplated by Section 301,
at the option of the Holder, Bearer Securities of any series may be exchanged
for Registered Securities of the same series of any authorized denominations and
of a like aggregate principal amount and tenor, upon surrender of the Bearer
Securities to be exchanged at any such office or agency, with all unmatured
coupons and all matured coupons in default thereto appertaining.  If the Holder
of a Bearer Security is unable to produce any such unmatured coupon or coupons
or matured coupon or coupons in default, any such permitted exchange may be
effected if the Bearer Securities are accompanied by payment in funds acceptable
to the Company in an amount equal to the face amount of such missing coupon or
coupons, or the surrender of such missing coupon or coupons may be waived by the
Company and the Trustee if there is furnished to them such security or
indemnity as they may require to save each of them and any Paying Agent
harmless.  If thereafter the Holder of such Security shall surrender to any
Paying Agent any such missing coupon in respect of which such a payment shall
have been made, such Holder shall be entitled to receive the amount of such
payment; provided, however, that, except as otherwise provided in Section 1002,
         -----------------                                                     
interest represented by coupons shall be payable only upon presentation and
surrender of those coupons at an office or agency located outside the United
States.  Notwithstanding the foregoing, in case a Bearer Security of any series
is surrendered at any such office or agency in a permitted exchange 


                                     -23-

 
for a Registered Security of the same series and like tenor after the close of
business at such office or agency on (i) any Regular Record Date and before the
opening of business at such office or agency on the relevant Interest Payment
Date, or (ii) any Special Record Date and before the opening of business at
such office or agency on the related proposed date for payment of Defaulted
Interest, such Bearer Security shall be surrendered without the coupon relating
to such Interest Payment Date or proposed date for payment, as the case may be,
and interest or Defaulted Interest, as the case may be, will not be payable on
such Interest Payment Date or proposed date for payment, as the case may be, in
respect of the Registered Security issued in exchange for such Bearer Security,
but will be payable only to the Holder of such coupon when due in accordance
with the provisions of this Indenture. Whenever any Securities are so
surrendered for exchange, the Company shall execute, and the Trustee shall
authenticate and deliver, the Securities which the Holder making the exchange is
entitled to receive.

          Notwithstanding the foregoing, except as otherwise specified as
contemplated by Section 301, any permanent global Security shall be exchangeable
only as provided in this paragraph. If the depositary for any permanent global
Security is "DTC," then, unless the terms of such global Security expressly
permit such global Security to be exchanged in whole or in part for definitive
Securities, a global Security may be transferred, in whole but not in part, only
to a nominee of DTC, or by a nominee of DTC to DTC, or to a successor to DTC for
such global Security selected or approved by the Company or to a nominee of such
successor to DTC. If at any time DTC notifies the Company that it is unwilling
or unable to continue as depositary for the applicable global Security or
Securities or if at any time DTC ceases to be a clearing agency registered under
the Exchange Act if so required by applicable law or regulation, the Company
shall appoint a successor depositary with respect to such global Security or
Securities. If (x) a successor depositary for such global Security or Securities
is not appointed by the Company within 90 days after the Company receives such
notice or becomes aware of such unwillingness, inability or ineligibility, (y)
an Event of Default has occurred and is continuing and the beneficial owners
representing a majority in principal amount of the applicable series of
Securities represented by such global Security or Securities advise DTC to cease
act ing as depositary for such global Security or Securities or (z) the Company,
in its sole discretion, determines at any time that all Outstanding Securities
(but not less than all) of any series issued or issuable in the form of one or
more global Securities shall no longer be represented by such global Security or
Securities, then the Company shall execute, and the Trustee shall authenticate
and deliver definitive Securities of like series, rank, tenor and terms in
definitive form in an aggregate principal amount equal to the principal amount
of such global Security or Securities. If any beneficial owner of an interest
in a permanent global Security is otherwise entitled to exchange such interest
for Securities of such series and of like tenor and principal amount of another
authorized form and denomination, as specified as contemplated by Section 301
and provided that any applicable notice provided in the permanent global
Security shall have been given, then without unnecessary delay but in any event
not later than the earliest date on which such interest may be so exchanged, the
Company shall execute, and the Trustee shall authenticate and deliver definitive
Securities in aggregate principal amount equal to the principal amount of such
beneficial owner's interest in such permanent global Security. On or after the
earliest date on which such interests may be so exchanged, such permanent
global Security shall be surrendered for exchange by DTC or such other
depositary as shall be specified in the Company Order with respect thereto to
the Trustee, as the Company's agent for such purpose; provided, however, that no
                                                      -----------------
such exchanges may occur during a period beginning at the opening of business 15
days before any selection of Securities to be redeemed and ending on the
relevant Redemption Date if the Security for which exchange is requested may be
among those selected for redemption; and provided further that no Bearer
                                         ----------------
Security delivered in exchange for a portion of a permanent global Security
shall be mailed or otherwise delivered to any location in the United States. If
a Registered Security is issued in exchange for any portion of a permanent
global Security after the close of business at the office or agency where such
exchange occurs on (i) any Regular Record Date and before the opening of
business at such office or agency on the relevant Interest Payment Date, or (ii)
any Special Record Date and the opening of business at such office or agency on
the related proposed date for payment of Defaulted Interest, interest or
Defaulted


                                     -24-

 
Interest, as the case may be, will not be payable on such Interest Payment Date
or proposed date for payment, as the case may be, in respect of such Registered
Security, but will be payable on such Interest Payment Date or proposed date
for payment, as the case may be, only to the Person to whom interest in respect
of such portion of such permanent global Security is payable in accordance with
the provisions of this Indenture.

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

          No service charge shall be made for any registration of transfer or
exchange of Securities, but the Company may 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 304, 906, 1107 or 1305 not involving any 
transfer.

          The Company, or the Trustee, as applicable, shall not be required (i)
to issue, register the transfer of or exchange any Security if such Security may
be among those selected for redemption during a period beginning at the opening
of business 15 days before selection of the Securities to be redeemed under
Section 1103 and ending at the close of business on (A) if such Securities are
issuable only as Registered Securities, the day of the mailing of the relevant
notice of redemption and (B) if such Securities are issuable as Bearer
Securities, the day of the first publication of the relevant notice of
redemption or, if such Securities are also issuable as Registered Securities and
there is no publication, the mailing of the relevant notice of redemption, or
(ii) to register the transfer of or exchange any Registered Security so
selected for redemption in whole or in part, except, in the case of any
Registered Security to be redeemed in part, the portion thereof not to be
redeemed, or (iii) to exchange any Bearer Security so selected for redemption
except that such a Bearer Security may be exchanged for a Registered Security of
that series and like tenor, provided that such Registered Security shall be
                            --------                                        
simultaneously surrendered for redemption, or (iv) to issue, register the
transfer of or exchange any Security which has been surrendered for repayment at
the option of the Holder, except the portion, if any, of such Security not to be
so repaid.

          SECTION 306.  Mutilated, Destroyed, Lost and Stolen Securities.  If
                        ------------------------------------------------     
any mutilated Security or a Security with a mutilated coupon appertaining to it
is surrendered to the Trustee or the Company, together with, in proper cases,
such security or indemnity as may be required by the Company or the Trustee to
save each of them or any agent of either of them harmless, the Company shall
execute and the Trustee shall authenticate and deliver in exchange therefor a
new Security of the same series and principal amount, containing identical terms
and provisions and bearing a number not contemporaneously outstanding, with
coupons corresponding to the coupons, if any, appertaining to the surrendered
Security.

          If there shall be delivered to the Company and to the Trustee (i)
evidence to their satisfaction of the destruction, loss or theft of any Security
or coupon, and (ii) such security or indemnity as may be required by them to
save each of them and any agent of either of them harmless, then, in the absence
of notice to the Company or the Trustee that such Security or coupon has been
acquired by a bona fide purchaser, the Company shall execute and upon its
request the Trustee shall authenticate and deliver, in lieu of any such
destroyed, lost or stolen Security or in exchange for the Security to which a
destroyed, lost or stolen coupon appertains (with all appurtenant coupons not


                                     -25-

 
destroyed, lost or stolen), a new Security of the same series and principal
amount, containing identical terms and provisions and bearing a number not
contemporaneously outstanding, with coupons corresponding to the coupons, if
any, appertaining to such destroyed, lost or stolen Security or to the Security
to which such destroyed, lost or stolen coupon appertains.

          Notwithstanding the provisions of the previous two paragraphs, in case
any such mutilated, destroyed, lost or stolen Security or coupon has become or
is about to become due and payable, the Company in its discretion may, instead
of issuing a new Security, with coupons corresponding to the coupons, if any,
appertaining to such destroyed, lost or stolen Security or to the Security to
which such destroyed, lost or stolen coupon appertains, pay such Security or
coupon; provided, however, that payment of the principal of (and premium, if
        -----------------                                                   
any) and interest on Bearer Securities shall, except as otherwise provided in
Section 1002, be payable only at an office or agency located outside the United
States and, unless otherwise specified as contemplated by Section 301, any
interest on Bearer Securities shall be payable only upon presentation and
surrender of the coupons appertaining thereto.

          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 of any series with its coupons, if any, issued
pursuant to this Section in lieu of any destroyed, lost or stolen Security, or
in exchange for a Security to which a destroyed, lost or stolen coupon
appertains, shall constitute an original additional contractual obligation of
the Company, whether or not the destroyed, lost or stolen Security and its
coupons, if any, or the destroyed, lost or stolen coupon 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 that
series and their coupons, if any, 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 or coupons.

          SECTION 307.  Payment of Interest; Interest Rights Preserved.  Except
                        ----------------------------------------------         
as otherwise specified with respect to a series of Securities in accordance with
the provisions of Section 301, interest on any Registered Security that 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 at the office or agency of the Company maintained
for such purpose pursuant to Section 1002; provided, however, that each
                                           -----------------           
installment of interest on any Registered Security may at the Company's option
be paid by (i) mailing a check for such interest, payable to or upon the written
order of the Person entitled thereto pursuant to Section 308, to the address of
such Person as it appears on the Security Register or (ii) transfer to an
account maintained by the payee located inside the United States.

          Unless otherwise provided as contemplated by Section 301 with respect
to the Securities of any series, payment of interest may be made, in the case
of a Bearer Security, by transfer to an account maintained by the payee with a
bank located outside the United States.

          Unless otherwise provided as contemplated by Section 301, every
permanent global Security will provide that interest, if any, payable on any
Interest Payment Date will be paid to DTC, Euroclear and/or CEDEL, as the case
may be, with respect to that portion of such permanent global Security held for
its account by Cede & Co. or the Common Depositary, as the case may be, for the


                                     -26-

 
purpose of permitting such party to credit the interest received by it in
respect of such permanent global Security to the accounts of the beneficial
owners thereof.

          In case a Bearer Security of any series is surrendered in exchange for
a Registered Security of such series after the close of business (at an office
or agency in a Place of Payment for such series) on any Regular Record Date and
before the opening of business (at such office or agency) on the next succeeding
Interest Payment Date, such Bearer Security shall be surrendered without the
coupon relating to such Interest Payment Date and interest will not be payable
on such Interest Payment Date in respect of the Registered Security issued in
exchange for such Bearer Security, but will be payable only to the Holder of
such coupon when due in accordance with the provisions of this Indenture.

          Except as otherwise specified with respect to a series of Securities
in accordance with the provisions of Section 301, any interest on any Registered
Security of any series that 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 thereof on the 
relevant Regular Record Date by virtue of having been such Holder, and such
Defaulted Interest may be paid by the Company at its election in each case, as
provided in clause (1) or (2) below:

          (1)  The Company may elect to make payment of any Defaulted Interest
to the Persons in whose names the Registered Securities of such series (or their
respective Predecessor Securities) are registered at the close of business on a
special Record Date for the payment of such Defaulted Interest, which shall be
fixed in the following manner. The Company shall notify the Trustee in writing
of the amount of Defaulted Interest proposed to be paid on each Registered
Security of such series and the date of the proposed payment (which shall not be
less than 20 days after such notice is received by the Trustee), and at the same
time the Company shall deposit with the Trustee an amount of money in the
currency or currencies, currency unit or units or composite currency or
currencies in which the Securities of such series are payable (except as
otherwise specified pursuant to Section 301 for the Securities of such series)
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
on or 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
days and not 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 each Holder of Registered
Securities of such series at his address as it appears in the Security Register
not less than 10 days prior to such Special Record Date. The Trustee may, in its
discretion, in the name and at the expense of the Company, cause a similar
notice to be published at least once in an Authorized Newspaper in each place of
payment, but such publications shall not be a condition precedent to the
establishment of 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 the Registered Securities of such series (or their respective Predecessor
Securities) are registered at the close of business on such Special Record Date
and shall no longer be payable pursuant to the following clause (2). In case a
Bearer Security of any series is surrendered at the office or agency in a Place
of Payment for such series in exchange for a Registered Security of such series
after the close of business at such office or agency on any Special Record Date
and before the opening of business at such office or agency on the related
proposed date for payment of Defaulted Interest, such Bearer Security shall be
surrendered without the coupon relating to such proposed date of payment and
Defaulted Interest will not be payable on such proposed date of payment in
respect of the Registered Security issued in exchange for such 


                                     -27-

 
Bearer Security, but will be payable only to the Holder of such coupon when due
in accordance with the provisions of this Indenture.

          (2)   The Company may make payment of any Defaulted Interest on the
Registered Securities of any series 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.

          Subject to the foregoing provisions of this Section and Section 305,
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 308.  Persons Deemed Owners.  Prior to due presentment of a
                        ---------------------                                
Registered Security for registration of transfer, the Company, the Trustee and
any agent of the Company or the Trustee may treat the Person in whose name such
Registered Security is registered as the owner of such Security for the purpose
of receiving payment of principal of (and premium or Make-Whole Amount, if any),
and (subject to Sections 305 and 307) interest on, such Registered Security and
for all other purposes whatsoever, whether or not such Registered Security be
overdue, and none of the Company, the Trustee or any agent of the Company or the
Trustee shall be affected by notice to the contrary.

          Title to any Bearer Security and any coupons appertaining thereto
shall pass by delivery. The Company, the Trustee and any agent of the Company
or the Trustee may treat the Holder of any Bearer Security and the Holder of any
coupon as the absolute owner of such Security or coupon for the purpose of
receiving payment thereof or on account thereof and for all other purposes
whatsoever, whether or not such Security or coupon be overdue, and none of the
Company, the Trustee or 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 of a Security in global form or for maintaining, supervising or
reviewing any records relating to such beneficial ownership interests.

          Notwithstanding the foregoing, with respect to any global Security,
nothing herein shall prevent the Company, the Trustee, or any agent of the
Company, or the Trustee, from giving effect to any written certification or
other authorization furnished by any depositary, as a Holder, with respect to
such global Security or impair, as between such depositary and owners of
beneficial interests in such global Security, the operation of customary
practices governing the exercise of the rights of such depositary (or its
nominee) as Holder of such global Security.

          SECTION 309.  Cancellation.  All Securities and coupons surrendered
                        ------------                                         
for payment, redemption, repayment at the option of the Holder, registration of
transfer or exchange or for credit against any sinking fund payment shall, if
surrendered to any Person other than the Trustee, be delivered to the Trustee,
and any such Securities and coupons and Securities and coupons surrendered
directly to the Trustee for any such purpose shall be promptly canceled 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 may deliver to the Trustee (or
to any other Person for delivery to the Trustee) for cancellation any Securities
previously authenticated hereunder which the Company has not issued and sold,
and all Securities so delivered shall be promptly canceled by the Trustee.  If
the Company shall so acquire any of the Securities, however, such acquisition
shall not operate as a redemption or satisfaction of the indebtedness
represented by such Securities unless and until the same are surrendered to the
Trustee for 


                                     -28-

 
cancellation.  No Securities shall be authenticated in lieu of or in
exchange for any Securities canceled as provided in this Section, except as
expressly permitted by this Indenture.  Canceled Securities and coupons held by
the Trustee shall be destroyed by the Trustee and the Trustee shall deliver a
certificate of such destruction to the Company, unless by the Company Order, the
Company directs their return to it.
 
          SECTION 310.  Computation of Interest.  Except as otherwise specified
                        -----------------------                                
as contemplated by Section 301 with respect to Securities of any series,
interest on the Securities of each series shall be computed on the basis of a
360-day year consisting of twelve 30-day months.

                                  ARTICLE FOUR
                           SATISFACTION AND DISCHARGE

          SECTION 401.  Satisfaction and Discharge of Indenture.  This Indenture
                        ---------------------------------------                 
shall upon Company Request cease to be of further effect with respect to any
series of Securities specified in such Company Request (except as to any
surviving rights of registration of transfer or exchange of Securities of such
series herein expressly provided for and any right to receive Additional
Amounts, as provided in Section 1007), and the Trustee, upon receipt of a
Company Order, and at the expense of the Company, shall execute proper
instruments acknowledging satisfaction and discharge of this Indenture as to
such series when,

          (1)   either

                (A) all Securities of such series theretofore authenticated and
delivered and all coupons, if any, appertaining thereto (other than (i) coupons
appertaining to Bearer Securities surrendered for exchange for Registered
Securities and maturing after such exchange, whose surrender is not required or
has been waived as provided in Section 305, (ii) Securities and coupons of such
series which have been destroyed, lost or stolen and which have been replaced or
paid as provided in Section 306, (iii) coupons appertaining to Securities called
for redemption and maturing after the relevant Redemption Date, whose surrender
has been waived as provided in Section 1106, and (iv) Securities and coupons of
such series for whose payment money has theretofore been deposited in trust or
segregated and held in trust by the Company and thereafter repaid to the Company
or discharged from such trust, as provided in Section 1003) have been delivered
to the Trustee for cancellation; or

                (B) all Securities of such series and, in the case of (i) or
(ii) below, any coupons appertaining thereto not theretofore delivered to the
Trustee for cancellation

                    (i)    have become due and payable, or

                    (ii)   will become due and payable at their Stated
Maturity within one year, or
 
                    (iii)  if redeemable at the option of the Company, are to
be called for redemption within one year under 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 (i), (ii) or (iii) above, has irrevocably
deposited or caused to be deposited with the Trustee as trust funds in trust
for the purpose an amount in the currency or currencies, currency unit or units
or composite currency or currencies in which the Securities of such series are
payable, sufficient to pay and discharge the entire indebtedness on such
Securities and such coupons not theretofore delivered to the Trustee for
cancellation, for principal (and premium, if any) and in-

                                      -29-

 
terest to the date of such deposit (in the case of Securities which have become
due and payable) or to the Stated Maturity or Redemption Date, as the case may
be;

          (2) the Company has paid or caused to be paid all other sums payable
hereunder by the Company; and

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

          Notwithstanding the satisfaction and discharge of this Indenture, the
obligations of the Company to the Trustee and any predecessor Trustee under
Section 606, the obligations of the Company to any Authenticating Agent under
Section 611 and, if money shall have been deposited with and held by the Trustee
pursuant to subclause (B) of clause (1) of this Section, the obligations of the
Trustee under Section 402 and the last paragraph of Section 1003 shall survive.

          SECTION 402.  Application of Trust Funds.  Subject to the provisions
                        --------------------------                            
of the last paragraph of Section 1003, all money deposited with the Trustee
pursuant to Section 401 shall be held in trust and applied by it, in accordance
with the provisions of the Securities, the coupons and this Indenture, to the
payment, either directly or through any Paying Agent (including the Company
acting as its own Paying Agent) as the Trustee may determine, to the Persons
entitled thereto, of the principal (and premium, if any), and any interest for
whose payment such money has deposited with or received by the Trustee, but such
money need not be segregated from other funds except to the extent required by
law.

                                  ARTICLE FIVE

                                    REMEDIES

          SECTION 501.  Events of Default.  "Event of Default," wherever used
                        -----------------                                    
herein with respect to any particular series of Securities, means any one of
the following events (whatever the reason for such Event of Default and whether
or not it shall be voluntary or involuntary or be effected by operation of law
or pursuant to any judgment, decree or order of any court or any order, rule or
regulation of any administrative or governmental body) unless such event is
specifically deleted or modified in or pursuant to the supplemental indenture,
Board Resolution or Officers' Certificate establishing the terms of such series
pursuant to this Indenture:

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

          (2) default in the payment of the principal of (or premium or Make-
Whole Amount, if any, on) any Security of that series when it becomes due and
payable at its Maturity; or

          (3) default in the performance, or breach, of any covenant or warranty
of the Company in this Indenture with respect to any Security of that series
(other than a covenant or warranty a default in whose performance or whose
breach is elsewhere in this Section specifically dealt with), and continuance of
such default or breach for a period of 60 days after there has been given, by
registered or certified mail to the Company, by the Trustee or to the Company,
and the Trustee by the Holders of at least 25% in principal amount of the
Outstanding Securities of that series a written notice specifying such default
or breach and requiring it to be remedied and stating that such notice is a
"Notice of Default" hereunder; or

                                      -30-

Company or any Guarantor, or under any mortgage, indenture or other instrument
of the Company or any Guarantor (including a default with respect to Securities
of any series other than that series) under which there may be issued or by
which there may be secured any Recourse Indebtedness of the Company or any
Guarantor (or by any Subsidiary of the Company or a Guarantor, the repayment of
which the Company or the Guarantor has guaranteed or for which the Company or
the Guarantor is directly responsible or liable as obligor or guarantor),
whether such Recourse Indebtedness now exists or shall hereafter be created,
which default shall constitute a failure to pay an aggregate principal amount
exceeding $5,000,000 of Recourse Indebtedness of any or all such Persons when
due and payable after the expiration of any applicable grace period with respect
thereto and shall have resulted in such Recourse Indebtedness in an aggregate
principal amount exceeding $5,000,000 becoming   or being declared due and
payable before the date on which it would otherwise have become due and payable,
without such Recourse Indebtedness having been discharged; or

          (5) the Company, a Guarantor or any Significant Subsidiary pursuant to
or within the meaning of any Bankruptcy Law:

              (A)  commences a voluntary case,

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

              (C)  consents to the appointment of a Custodian of it or for all
                   or substantially all of its property, or
 
              (D)  makes a general assignment for the benefit of its creditors;
                   or

          (6) a court of competent jurisdiction enters an order or decree under

                   Significant Subsidiary in an involuntary case,
 
              (B)  appoints a Custodian of the Company, a Guarantor or any
                   Significant Subsidiary or for all or substantially all of
                   either of its property, or

              (C)  orders the liquidation of the Company, a Guarantor or any
                   Significant Subsidiary, 

and the order or decree remains unstayed and in effect for 90 days; or
 
          (7) the guarantee of any security by a Guarantor ceases to be, or is
asserted in writing by the Company or any Guarantor not to be, in full force and
effect or enforceable in accordance with its terms, or
 
          (8) any other Event of Default provided with respect to Securities of
that series.

similar official under any Bankruptcy Law.

          SECTION 502.  Acceleration of Maturity; Rescission and Annulment.  If
                        --------------------------------------------------     
an Event of Default with respect to Securities of any series at the time
Outstanding occurs and is continuing, then and in every such case the Trustee or
the Holders of not less than 25% in principal amount of 

                                      -31-

 
the Outstanding Securities of that series may declare the principal (or, if any
Securities are Original Issue Discount Securities or Indexed Securities, such
portion of the principal as may be specified in the terms thereof) and premium
(if any) of all the Securities of that series to be due and payable immediately,
by a notice in writing to the Company, (and to the Trustee if given by the
Holders), and upon any such declaration such principal and premium (if any) or
specified portion thereof shall become immediately due and payable.

          At any time after such a declaration of acceleration with respect to
Securities of any series has been made 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 that series, by written notice to the Company and the
Trustee, may rescind and annul such declaration and its consequences if:

          (1) the Company has paid or deposited with the Trustee a sum
sufficient to pay in the currency, currency unit or composite currency in which
the Securities of such series are payable (except as otherwise specified
pursuant to Section 301 for the Securities of such series):

                (A) all overdue installments of interest on all Outstanding
Securities of that series and any related coupons,

                (B) the principal of (and premium, if any, on) any Outstanding
Securities of that series which have become due otherwise than by such
declaration of acceleration and interest thereon at the rate or rates borne by
or provided for in such Securities,

                (C) to the extent that payment of such interest is lawful,
interest upon overdue installments of interest at the rate or rates borne by or
provided for in such Securities, and
 
                (D) all sums paid or advanced by the Trustee hereunder and the
reasonable compensation, expenses, disbursements and advances of the Trustee,
its agents and counsel; and

          (2) all Events of Default with respect to Securities of that series,
other than the nonpayment of the principal of (or premium, if any) or interest
on Securities of that series which have become due solely by such declaration of
acceleration, have been cured or waived as provided in Section 513.

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

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

          (1) default is made in the payment of any installment of interest on
any Security of any series and any related coupon when such interest becomes due
and payable and such default continues for a period of 30 days, or

          (2) default is made in the payment of the principal of (or premium ,
if any, on) any Security of any series at its Maturity, then the Company will,
upon demand of the Trustee, pay to the Trustee, for the benefit of the Holders
of such Securities of such series and coupons, the whole amount then due and
payable on such Securities and coupons for principal (and premium, if any) and
interest, with interest upon any overdue principal (and premium, if any) and, to
the extent that payment of such interest shall be legally enforceable, upon any
overdue installments of interest, at the rate or rates borne by or provided for
in such Securities, and, in addition thereto, such further 

                                      -32-

 
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.

          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 such Securities of such series
and collect the moneys 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 of such series, wherever situated.

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

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

          (i) to file and prove a claim for the whole amount, or such lesser
amount as may be provided for in the Securities of such series, of principal
(and premium, if any) and interest owing and unpaid in respect of the Securities
and to file such other papers or documents as may be necessary or 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 of the Holders allowed in such judicial proceeding, and

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

          and any custodian, receiver, assignee, trustee, liquidator,
sequestrator (or other similar official) in any such judicial proceeding is
hereby authorized by each Holder of Securities of such series and coupons to
make such payments to the Trustee, and in the event that the Trustee shall
consent to the making of such payments directly to the Holders, to pay to the
Trustee any amount due to it for the reasonable compensation, expenses,
disbursements and advances of the Trustee and any predecessor Trustee, their
agents and counsel, and any other amounts due the Trustee or any predecessor
Trustee under Section 606.

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

          SECTION 505.  Trustee May Enforce Claims Without Possession of
                        ------------------------------------------------
Securities or Coupons.  All rights of action and claims under this Indenture or
- ---------------------                                                          
any of the Securities or coupons may be prosecuted and enforced by the Trustee
without the possession of any of the Securities or 

                                      -33-

 
coupons or the production thereof in any proceeding relating thereto, and any
such proceeding instituted by the Trustee shall be brought in its own name as
trustee of an express trust, and any recovery of judgment shall, after
provision for the payment of the reasonable compensation, expenses, 
disbursements and advances of the Trustee, its agents and counsel, be for the
ratable benefit of the Holders of the Securities and coupons in respect of which
such judgment has been recovered.

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

          FIRST:    To the payment of all amounts due the Trustee and any
predecessor Trustee under Section 606;

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

          THIRD:    To the payment of the remainder, if any, to the Person or
Persons entitled thereto.

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

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

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

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

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

          (5) no direction inconsistent with such written request has been given
to the Trustee during such 60-day period by the Holders of a majority in
principal amount of the Outstanding Securities of that series; it being
understood and intended that no one or more of such Holders shall have any right
in any manner whatever by virtue of, or by availing of, any provision of this
Indenture to affect, disturb or prejudice the rights of any other of such
Holders, or to obtain or to seek to obtain priority or preference over any other
of such Holders or to enforce any right under this Indenture, except in the
manner herein provided and for the equal and ratable benefit of all such
Holders.

          SECTION 508.  Unconditional Right of Holders to Receive Principal

(Premium, if any) and Interest.  Notwithstanding any other provision in this
- ------------------------------                                              
Indenture, the Holder of any Secu-

                                      -34-

 
rity or coupon shall have the right which is absolute and unconditional to
receive payment of the principal of (and premium, if any) and (subject to
Sections 305 and 307) interest on such Security or payment of such coupon on the
respective due dates expressed in such Security or coupon (or, in the case of
redemption, on the Redemption Date) and to institute suit for the enforcement of
any such payment, and such rights shall not be impaired without the consent of
such Holder.

          SECTION 509.  Restoration of Rights and Remedies.  If the Trustee or
                        ----------------------------------                    
any Holder of a Security or coupon has instituted any proceeding to enforce any
right or remedy under this Indenture and such proceeding has been discontinued
or abandoned for any reason, or has been determined adversely to the Trustee or
to such Holder, then and in every such case, the Company, the Trustee and the
Holders of Securities and coupons shall, subject to any determination in such
proceeding, be restored severally and respectively to their former positions
hereunder and thereafter all rights and remedies of the Trustee and the Holders
shall continue as though no such proceeding had been instituted.

          SECTION 510.  Rights and Remedies Cumulative.  Except as otherwise
                        ------------------------------                      
provided with respect to the replacement or payment of mutilated, destroyed,
lost or stolen Securities or coupons in the last paragraph of Section 306, no
right or remedy herein conferred upon or reserved to the Trustee or to the
Holders of Securities or coupons is intended to be exclusive of any other right
or remedy, and every right and remedy shall, to the extent permitted by law, be
cumulative and in addition to every other right and remedy given hereunder or
now or hereafter existing at law or in equity or otherwise.  The assertion or
employment of any right or remedy hereunder, or otherwise, shall not prevent the
concurrent assertion or employment of any other appropriate right or remedy.

          SECTION 511.  Delay or Omission Not Waiver.  No delay or omission of
                        ----------------------------                          
the Trustee or of any Holder of any Security or coupon 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
Holders may be exercised from time to time, and as often as may be deemed
expedient, by the Trustee or by the Holders of Securities or coupons, as the
case may be.

          SECTION 512.  Control by Holders of Securities.  The Holders of not
                        --------------------------------                     
less than a majority in principal amount of the Outstanding Securities of any
series shall have the right to direct the time, method and place of conducting
any proceeding for any remedy available to the Trustee or exercising any trust
or power conferred on the Trustee with respect to the Securities of such series,
                                                                                
provided that
- --------     
          (1) such direction shall not be in conflict with any rule of law or
with this Indenture,

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

          (3) the Trustee need not take any action which might involve it in
personal liability or be unduly prejudicial to the Holders of Securities of
such series not joining therein.

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

          (1) in the payment of the principal of (or premium, if any) or
interest on any Security of such series or any related coupons, or

                                      -35-

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

          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 Event of Default or impair any right consequent thereon.

          SECTION 514.  Waiver of Usury, Stay or Extension Laws.  The Company
                        ---------------------------------------              
covenants (to the extent that it may lawfully do so) that it will not at any
time insist upon, or plead, or in any manner whatsoever claim or take the
benefit or advantage of, any usury, stay or extension law wherever enacted, now
or at any time hereafter in force, which may affect the covenants or the 
performance of this Indenture; and the Company (to the extent that it may
lawfully do so) hereby expressly waives all benefit or advantage of any such
law, and covenants that it will not hinder, delay or impede the execution of any
power herein granted to the Trustee, but will suffer and permit the execution of
every such power as though no such law had been enacted.

          SECTION 515.  Undertaking for Costs.  All parties to this Indenture
                        ---------------------                                
agree, and each Holder of any Security by his acceptance thereof shall be deemed
to have agreed, that any court may in its discretion require, in any suit for
the enforcement of any right or remedy under this Indenture, or in any suit
against the Trustee for any action taken or omitted by it as Trustee, the filing
by any party litigant in such suit of any 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 Holder, or group
of Holders, holding in the aggregate more than 10% in principal amount of the
Outstanding Securities, or to any suit instituted by any Holder for the
enforcement of the payment of the principal of (or premium or Make-Whole Amount,
if any) or interest on any Security on or after the respective Stated Maturities
expressed in such Security (or, in the case of redemption, on or after the
Redemption Date).

                                  ARTICLE SIX

                                  THE TRUSTEE

          SECTION 601.  Notice of Defaults.  Within 90 days after the occurrence
                        ------------------                                      
of any default hereunder with respect to the Securities of any series, the
Trustee shall transmit in the manner and to the extent provided in TIA Section
313(c), 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 fund
installment with respect to the Securities of such series, the Trustee shall be
protected in withholding such notice if and so long as Responsible Officers of
the Trustee in good faith determine that the withholding of such notice is in
the interests of the Holders of the Securities and coupons of such series; and
provided further that in the case of any default or breach of the character
- ----------------                                                            
specified in Section 501(3) with respect to the Securities and coupons of such
series, no such notice to Holders shall be given until at least 60 days after
the occurrence thereof.  For the purpose of this Section, the term "default"
means any event which is, or after notice or lapse of time or both would become,
an Event of Default with respect to the Securities of such series.

          SECTION 602.  Certain Rights of Trustee.  Subject to the provisions of
                        -------------------------                               
TIA Section 315(a) through 315(d):

                                      -36-

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

          (2) any request or direction of the Company mentioned herein shall be
sufficiently evidenced by a Company Request or Company Order (other than
delivery of any Security, together with any coupons appertaining thereto, to the
Trustee for authentication and delivery pursuant to Section 303 which shall be
sufficiently evidenced as provided therein) and any resolution of the Board of
Directors may be sufficiently evidenced by a Board Resolution;

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

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

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

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

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

          (8) the Trustee shall not be liable for any action taken, suffered or
omitted by it in good faith and reasonably believed by it to be authorized or
within the discretion or rights or powers conferred upon it by this Indenture.

          The Trustee shall not be required 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.

          Except during the continuance of an Event of Default, the Trustee
undertakes to perform only such duties as are specifically set forth in this
Indenture, and no implied covenants or obligations shall be read into this
Indenture against the Trustee.

          SECTION 603.  Not Responsible for Recitals or Issuance of Securities.
                        ------------------------------------------------------  
The recitals contained herein and in the Securities, except the Trustee's
certificate of authentication, and in any 

                                      -37-

 
coupons shall be taken as the statements of the Company and neither the Trustee
nor any Authenticating Agent assumes any responsibility for their correctness.
The Trustee makes no representations as to the validity or sufficiency of this
Indenture or of the Securities or coupons, except that the Trustee represents
that it is duly authorized to execute and deliver this Indenture, authenticate
the Securities and perform its obligations hereunder. Neither the Trustee nor
any Authenticating Agent shall be accountable for the use or application by the
Company of Securities or the proceeds thereof.

          SECTION 604.  May Hold Securities.  The Trustee, any Paying Agent,
                        -------------------                                 
Security Registrar, Authenticating Agent or any other agent of the Company, in
its individual or any other capacity, may become the owner or pledgee of
Securities and coupons and, subject to TIA Sections 310(b) and 311, may
otherwise deal with the Company with the same rights it would have if it were
not the Trustee, Paying Agent, Security Registrar, Authenticating Agent or such
other agent.

          SECTION 605.  Money Held in Trust.  Money held by the Trustee in trust
                        -------------------                                     
hereunder need not be segregated from other funds except to the extent required
by law.  The Trustee shall be under no liability for interest on any money
received by it hereunder except as otherwise agreed with the Company.

          SECTION 606.  Compensation and Reimbursement.  The Company agrees:
                        ------------------------------                      

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

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

          (3) to indemnify each of the Trustee and any predecessor Trustee for,
and to hold it harmless against, any loss, liability or expense incurred without
negligence or bad faith on its own part, arising out of or in connection with
the acceptance or administration of the trust or trusts hereunder, 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.

          When the Trustee incurs expenses or renders services in connection
with an Event of Default specified in Section 501(5) or Section 501(6), the
expenses (including the reasonable charges and expenses of its counsel) and the
compensation for the services are intended to constitute expenses of
administration under any applicable Federal or state bankruptcy, insolvency or
other similar law.

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

          The provisions of this Section shall survive the termination of this
Indenture.

          SECTION 607.  Corporate Trustee Required; Eligibility; Conflicting
                        ----------------------------------------------------
Interests.  There shall at all times be a Trustee hereunder which shall be
- ---------                                                                 
eligible to act as Trustee under TIA Section 310(a)(1) and shall have a combined
capital and surplus of at least $50,000,000.  If such corporation publishes
reports of condition at least annually, pursuant to law or the requirements of
Federal, State, Territorial or District of Columbia supervising or examining
authority, then for the purposes 

                                      -38-

 
of this Section, the combined capital and surplus of such corporation shall be
deemed to be its combined capital and surplus as set forth in its most recent
report of condition so published. If at any time the Trustee shall cease to be
eligible in accordance with the provisions of this Section, it shall resign
immediately in the manner and with the effect hereinafter specified in this
Article.

          SECTION 608.  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 in accordance with the applicable
requirements of Section 609.

          (b) The Trustee may resign at any time with respect to the Securities
of one or more series 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 at any time with respect to the
Securities of any series by Act of the Holders of a majority in principal amount
of the Outstanding Securities of such series delivered to the Trustee and the
Company.

          (d) If at any time:

              (1)   the Trustee shall fail to comply with the provisions of TIA
Section 310(b) after written request therefor by the Company or by any Holder of
a Security who has been a bona fide Holder of a Security for at least six
months, or

              (2)   the Trustee shall cease to be eligible under Section 607 and
shall fail to resign after written request therefor by the Company or by any
Holder of a Security who has been a bona fide Holder of a Security for at least
six months, or

              (3)   the Trustee shall become incapable of acting or shall be
adjudged a bankrupt or insolvent or a receiver of the Trustee or of its property
shall be appointed or any public officer shall take charge or control of the
Trustee or of its property or affairs for the purpose of rehabilitation,
conservation or liquidation, then, in any such case, (i) the Company by or
pursuant to a Board Resolution may remove the Trustee and appoint a successor
Trustee with respect to all Securities, or (ii) subject to TIA Section 315(e),
any Holder of a Security who has been a bona fide Holder of a Security 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
with respect to all Securities and the appointment of a successor Trustee or
Trustees.

          (e) If the Trustee shall resign, be removed or become incapable of
acting, or if a vacancy shall occur in the office of Trustee for any cause with
respect to the Securities of one or more series, the Company, by or pursuant to
a Board Resolution, shall promptly appoint a successor Trustee or Trustees with
respect to the Securities of that or those series (it being understood that any
such successor Trustee may be appointed with respect to the Securities of one or
more or all of such series and that at any time there shall be only one Trustee
with respect to the Securities of any particular series).  If, within one year
after such resignation, removal or incapability, or the occurrence of such
vacancy, a successor Trustee with respect to the Securities of any series shall
be appointed by Act of the Holders of a majority in principal amount of the
Outstanding Securities of such series delivered to the Company and the retiring
Trustee, the successor Trustee so appointed shall, forthwith upon its acceptance
or such appointment, become the successor Trustee with respect to the Securities
of such series and to that extent supersede the successor Trustee appointed by
the Company.  If no successor Trustee with respect to the Securities of any
series shall have been so appointed by the Company or the Holders of Securities
and accepted appointment in the manner hereinafter provided, 

                                      -39-

 
any Holder of a Security who has been a bonafide 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
appointment of a successor Trustee with respect to Securities of such series.

          (f) The Company shall give notice of each resignation and each removal
of the Trustee with respect to the Securities of any series and each appointment
of a successor Trustee with respect to the Securities of any series in the
manner provided for notices to the Holders of Securities in Section 106.  Each
notice shall include the name of the successor Trustee with respect to the 
Securities of such series and the address of its Corporate Trust Office.

          SECTION 609.  Acceptance of Appointment by Successor.  (a) In case of
                        --------------------------------------                 
the appointment hereunder of a successor Trustee with respect to all Securities,
every such successor Trustee shall execute, acknowledge and deliver to the
Company and the retiring Trustee an instrument accepting such appointment, and
thereupon the resignation or removal of the retiring Trustee shall become
effective and such successor Trustee, without any further act, deed or
conveyance, shall become vested with all the rights, powers, trusts and duties
of the retiring Trustee; but, on request of the Company or the successor
Trustee, such retiring Trustee shall, upon payment of its charges, execute and
deliver an instrument transferring to such successor Trustee all the rights,
powers and trusts of the retiring Trustee, and shall duly assign, transfer and
deliver to such successor Trustee all property and money held by such retiring
Trustee hereunder, subject nevertheless to its claim, if any, provided for in
Section 606.

          (b) 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
retiring Trustee and each successor Trustee with respect to the Securities of
one or more series shall execute and deliver an indenture supplemental hereto,
pursuant to Article Nine hereof, wherein each successor Trustee shall accept
such appointment and which (1) shall contain such provisions as shall be
necessary or desirable to transfer and confirm to, and to vest in, each
successor Trustee all the rights, powers, trusts and duties of the retiring
Trustee with respect to the Securities of that or those series to which the 
appointment of such successor Trustee relates, (2) if the retiring Trustee is
not retiring with respect to all Securities, shall contain such provisions as
shall be deemed necessary or desirable to confirm that all the rights, powers,
trusts and duties of the retiring Trustee with respect to the Securities of that
or those series as to which the retiring Trustee is not retiring shall continue
to be vested in the retiring Trustee, and (3) shall add to or change any of the
provisions of this Indenture as shall be necessary to provide for or facilitate
the administration of the trusts hereunder by more than one Trustee, it being
understood that nothing herein or in such supplemental indenture shall
constitute such Trustees co-trustees of the same trust and that each such
Trustee shall be trustee of a trust or trusts hereunder separate and apart from
any trust or trusts hereunder administered by any other such Trustee; and upon
the execution and delivery of such supplemental indenture the resignation or
removal of the retiring Trustee shall become effective to the extent provided
therein and each such successor Trustee, without any further act, deed or
conveyance, shall become vested with all the rights, powers, trusts and duties
of the retiring Trustee with respect to the Securities of that or those series
to which the appointment of such successor Trustee relates; but, on request of
the Company, or any successor Trustee, such retiring Trustee shall duly assign,
transfer and deliver to such successor Trustee all property and money held by
such retiring Trustee hereunder with respect to the Securities of that or those
series to which the appointment of such successor Trustee relates.

          (c) Upon request of any such successor Trustee, the Company shall
execute any and all instruments for more fully and certainly vesting in and
confirming to such successor Trustee all such rights, powers and trusts referred
to in paragraph (a) or (b) of this Section, as the case may be.

          (d) No successor Trustee shall accept its appointment unless at the
time of such acceptance such successor Trustee shall be qualified and eligible
under this Article.

                                      -40-

 
          SECTION 610.  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 or coupons 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 of coupons so
authenticated with the same effect as if such successor Trustee had itself
authenticated such Securities or coupons.  In case any Securities or coupons
shall not have been authenticated by such predecessor Trustee, any such
successor Trustee may authenticate and deliver such Securities or coupons, in
either its own name or that of its predecessor Trustee, with the full force and
effect which this Indenture provides for the certificate of authentication of
the Trustee.

          SECTION 611.  Appointment of Authenticating Agent.  At any time when
                        -----------------------------------                   
any of the Securities remain Outstanding, the Trustee may appoint an
Authenticating Agent or Agents with respect to one or more series of Securities
which shall be authorized to act on behalf of the Trustee to authenticate
Securities of such series issued upon exchange, registration of transfer or
partial redemption or repayment thereof, 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.  Any such
appointment shall be evidenced by an instrument in writing signed by a 
Responsible Officer of the Trustee, a copy of which instrument shall be promptly
furnished to the Company.  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 bank or trust company or corporation
organized and doing business and in good standing under the laws of the United
States of America or of any State or the District of Columbia, authorized under
such laws to act as Authenticating Agent, having a combined capital and surplus
of not less than $50,000,000 and subject to supervision or examination by
Federal or State authorities.  If such Authenticating Agent publishes reports of
condition at least annually, pursuant to law or the requirements of the
aforesaid 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.  In case at any time an Authenticating Agent
shall cease to be eligible in accordance with the provisions of this Section,
such Authenticating Agent shall resign immediately in the manner and with the
effect specified in this Section.

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

          An Authenticating Agent for any series of Securities may at any time
resign by giving written notice of resignation to the Trustee for such series
and to the Company.  The Trustee for any series of Securities may at any time
terminate the agency of an Authenticating Agent by giving written notice of
termination to such Authenticating Agent and 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 for such series may appoint a successor
Authenticating Agent which shall be acceptable to the Company and shall 

                                      -41-

 
give notice of such appointment to all Holders of Securities of the series with
respect to which such Authenticating Agent will serve in the manner set forth in
Section 106. 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 herein. No successor Authenticating Agent shall be
appointed unless eligible under the provisions of this Section.

          The Company agrees to pay to each Authenticating Agent from time to
time reasonable compensation including reimbursement of its reasonable expenses
for its services under this Section.

          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 or in lieu of the Trustee's certificate of authentication, an
alternate certificate of authentication substantially in the following form:

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

Guarantor may consolidate with, or sell, lease or convey all or substantially
all of its assets to, or merge with or into any other entity, provided that in
any such case, (1) either the Company or the Guarantor, as the case may be, will
be the continuing entity, or the successor entity will be an entity organized
and existing under the laws of the United States or a State thereof and such
successor entity expressly assumes the due and punctual performance and
observance of all of the covenants and conditions of this Indenture to be
performed by the Company or the Guarantor, as the case may be, by supplemental
indenture, complying with Article Nine hereof, satisfactory to the Trustee,
executed and delivered to the Trustee by such entity and (ii) immediately after
giving effect to such transaction and treating any indebtedness which becomes
an obligation of the Company, a Guarantor or any Subsidiary as a result thereof
as having been incurred by the Company, the Guarantor or such Subsidiary at the

or the Guarantor, as applicable, and the predecessor entity, except in the
event of a lease, shall be relieved of any further obligation under this
Indenture and the Securities. Any such successor entity of the Company thereupon
may cause to be signed, and may issue either in its own name or in the name of
the Company any or all of the Securities issuable hereunder which theretofore
shall not have been signed by the Company and delivered to the Trustee; and,
upon the order of such successor entity, instead of the Company, and subject to
all the terms, conditions and limitations in this Indenture prescribed, the
Trustee shall authenticate and shall deliver any Securities which previously
shall have been signed and delivered by the officers of the Company to the
Trustee for authentication, and any Securities which such successor entity
thereafter shall cause to be signed and delivered to the Trustee for that
purpose. All the Securities so issued shall in all respects have the same legal
rank and benefit under this Indenture as the Securities theretofore or
thereafter issued in accordance with the terms of this Indenture as though all
of such Securities had been issued at the date of the execution hereof.

also subject to the condition that the Trustee receive an Officers' Certificate
and an Opinion of Counsel to the effect that any such consolidation, merger,
sale, lease or conveyance, and the assumption by any successor entity, complies
with the provisions of this Article and that all conditions precedent herein
provided for relating to such transaction have been complied with.

hereunder by more than one Trustee; or

          (9)  to cure any ambiguity, to correct or supplement any provision
herein which may be defective or inconsistent with any other provision herein,
or to make any other provisions with respect to matters or questions arising
under this Indenture which shall not be inconsistent with the provisions of this
Indenture, provided such provisions do not adversely affect the interests of the
Holders of Securities of any series or any related coupons in any material
respect; or

extent as shall be necessary to permit or facilitate the defeasance and

all Outstanding Securities affected by such supplemental indenture, by Act of
said Holders delivered to the Company and the Trustee, the Company, when
authorized by or pursuant to a Board Resolution, the Guarantors and the Trustee
may enter into an indenture or indentures supplemental hereto for the purpose of
adding any provisions to or changing in any manner or eliminating any of the
provisions of this Indenture or of modifying in any manner the rights of the
Holders of Securities and any related coupons under this Indenture; provided,
                                                                    ---------

each series of Securities that it will duly and punctually pay the principal of

Unless otherwise specified with respect to Securities of any series pursuant to
Section 301, at the option of the Company, all payments of principal may be paid
by check to the registered Holder of the Registered Security or other person
entitled thereto against surrender of such Security.

          SECTION 1002.  Maintenance of Office or Agency.  If Securities of a

Securities of that series may be presented or surrendered for payment or
conversion, where Securities of that series may be surrendered for registration
of transfer or exchange and where notices and demands to or upon the Company in
respect of the Securities of that series and this Indenture may be served.  If

surrendered for payment or conversion, where any Registered Securities of that

laws or regulations applicable thereto, in a Place of Payment for that series
which is located outside the United States, an office or agency where Securities
of that series and related coupons may be presented and surrendered for payment
(including payment of any Additional Amounts payable on Securities of that
series pursuant to Section 1007) or conversion; provided, however, that if the

other stock exchange located outside the United States and such stock exchange
shall so require, the Company will maintain a Paying Agent for the Securities of
that series in Luxembourg or any other required city located outside the United
States, as the case may be, so long as the Securities of that series are listed
on such exchange; and (C) subject to any laws or regulations applicable thereto,
in a Place of Payment for that series located outside the United States an
office or agency where any Registered Securities of that series may be

where notices and demands to or upon the Company in respect of the Securities of
that series and this Indenture may be served. The Company will give prompt
written notice to the Trustee of the location, and any change in the location,
of each such office or agency. If at any time the Company shall fail to 
maintain any such required office or agency or shall fail to furnish the Trustee
with the address thereof, such presentations, surrenders, notices and demands
may be made or served at the Corporate Trust Office of the Trustee, except that
Bearer Securities of that series and the related coupons may be presented and
surrendered for payment (including payment of any Additional Amounts payable on
Bearer Securities of that series pursuant to Section 1007) or conversion at the
offices specified in the Security, in London, England, and the Company hereby
appoint the same as its agent to receive such respective presentations,
surrenders, notices and demands, and the Company hereby appoint the Trustee its
agent to receive all such presentations, surrenders, notices and demands.

          Unless otherwise specified with respect to any Securities pursuant to
Section 301, no payment of principal, premium or interest on Bearer Securities
shall be made at any office or agency of the Company in the United States or by
check mailed to any address in the United States or by transfer to an account
maintained with a bank located in the United States; provided, however, that, if
                                                     -----------------          
the Securities of a series are payable in Dollars, payment of principal of and
any premium and interest on any Bearer Security (including any Additional
Amounts payable on Securities of such series pursuant to Section 1007) shall be
made at the office of the Company's Paying Agent in the Borough of Manhattan,
The City of New York, if (but only if) payment in Dollars of the full amount of
such principal, premium or interest, as the case may be, at all offices or
agencies outside the United States maintained for the purpose by the Company in
accordance with this Indenture, is illegal or effectively precluded by exchange
controls or other similar restrictions.

          The Company may from time to time designate one or more other offices
or agencies where the Securities of one or more series may be presented or
surrendered for any or all of such purposes, and may from time to time rescind
such designations; provided, however, that no such designation or rescission
                   -----------------                                        
shall in any manner relieve the Company of its obligation to maintain an office
or agency in accordance with the requirements set forth above for Securities of
any series for such purposes.  The Company will give prompt written notice to
the Trustee of any such designation or rescission and of any change in the
location of any such other office or agency.  Unless otherwise specified with
respect to any Securities pursuant to Section 301 with respect to a series of
Securities, the Company hereby designates as a Place of Payment for each series
of Securities the office or agency of the Company in the Borough of Manhattan,
The City of New York, and initially appoints the Trustee at its Corporate Trust
Office as Paying Agent in such city and as its agent to receive all such
presentations, surrenders, notices and demands.

          Unless otherwise specified with respect to any Securities pursuant to
Section 301, if and so long as the Securities of any series (i) are denominated
in a Foreign Currency or (ii) may be payable in a Foreign Currency, or so long
as it is required under any other provision of the Indenture, then the Company
will maintain with respect to each such series of Securities, or as so 
required, at least one exchange rate agent.

          SECTION 1003.  Money for Securities Payments to Be Held in Trust.  If
                         -------------------------------------------------     
the Company shall at any time act as its own Paying Agent with respect to any
series of any Securities and any related coupons, it will, on or before each due
date of the principal of (and premium, if any), or interest on, any of the
Securities of that series, segregate and hold in trust for the benefit of the
Per sons entitled thereto a sum in the currency or currencies, currency unit or
units or composite currency or currencies in which the Securities of such
series are payable (except as otherwise specified pursuant to Section 301 for
the Securities of such series) sufficient to pay the principal (and premium, if
any) or interest so becoming due until such sums shall be paid to such Persons
or otherwise disposed of as herein provided, and will promptly notify the
Trustee of its action or failure so to act.

                                     -48-

 
          Whenever the Company shall have one or more Paying Agents for any
series of Securities and any related coupons, it will, on or before each due
date of the principal of (and premium, if any) or interest on, any Securities of
that series, deposit with a Paying Agent a sum (in the currency or currencies,
currency unit or units or composite currency or currencies described in the pre-
ceding paragraph) 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 to
execute and deliver to the Trustee an instrument in which such Paying Agent
shall agree with the Trustee, subject to the provisions of this Section, that
such Paying Agent will

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

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

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

          The Company may at any time, for the purpose of obtaining the
satisfaction and discharge of this Indenture 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, 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 sums.

          Except as otherwise provided in the Securities of any series, 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) and interest has become due and
payable shall be paid to the Company upon 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 of such principal of (and premium, if any) or interest on
any Security, without interest thereon, 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; provided, however, that the Trustee
                                           -----------------                  
or such Paying Agent, before being required to make any such repayment, may at
the expense of the Company cause to be published once, in an Authorized
Newspaper, notice that such money remains unclaimed and that, after a date
specified therein, which shall not be less than 30 days from the date of such
publication, any unclaimed balance of such money then remaining will be repaid
to the Company.

          SECTION 1004.  Existence.  Subject to Article Eight, the Company will
                         ---------                                             
do or cause to be done all things necessary to preserve and keep in full force
and effect the existence, rights and franchises of itself and of each Guarantor;
provided, however, that the Company shall not be required to preserve any right
- -----------------                                                               
or franchise if the Board of Directors determines that the preservation thereof
is no longer desirable in the conduct of the business of the Company and the
Guarantors taken as a whole and that the loss thereof is not disadvantageous in
any material respect to the Holders; and provided further that any Guarantor may
                                         -------- -------                       
consolidate with, merge into, or sell convey, 

                                     -49-

 
transfer, lease or otherwise dispose of all or part of its property and assets
to the Company or any other Guarantor.

          SECTION 1005.  Maintenance of Properties.  The Company will cause all
                         -------------------------                             
of the properties of itself and of each Subsidiary used or useful in the
conduct of its business or the business of any Subsidiary to be maintained and
kept in good condition, repair and working order and supplied with all necessary
equipment and will cause to be made all necessary repairs, renewals, 
replacements, betterments and improvements thereof, all as in the judgment of 
the Company may be necessary so that the business carried on in connection
therewith may be properly and advantageously conducted at all times; provided,
                                                                     ---------
however, the Company and its Subsidiaries shall not be prevented from
- -------                                                              
discontinuing the operation and maintenance of any of such properties if such
discontinuance is, in the judgment of the Company, desirable in the conduct of
its business and not disadvantageous in any material respect to the Holders..

          SECTION 1006.  Insurance.  The Company will, and will cause each of
                         ---------                                           
its Subsidiaries to, keep all of its insurable properties insured against loss
or damage at least equal to their then full insurable value.

          SECTION 1007.  Payment of Taxes and other Claims.  The Company will
                         ---------------------------------                   
pay or discharge or cause to be paid or discharged, before the same shall
become delinquent, (1) all material taxes, assessments and governmental charges
levied or imposed upon it or any Subsidiary or upon the income, profits or
property of the Company or any Subsidiary, and (2) all material lawful claims
for labor, materials and supplies which, if unpaid, might by law become a lien
upon the property of the Company or any Subsidiary; provided, however, that the
                                                    -----------------          
Company shall not be required to pay or discharge or cause to be paid or
discharged any such tax, assessment, charge or claim whose amount, applicability
or validity is being contested in good faith by appropriate proceedings.

          SECTION 1008.  Statement as to Compliance.  The Company will deliver
                         --------------------------                           
to the Trustee, within 180 days after the end of each fiscal year, a brief
certificate from its principal executive officer, principal financial officer or
principal accounting officer as to his or her knowledge of the Company's and
each Guarantor's compliance with all conditions and covenants under this
Indenture and, in the event of any noncompliance, specifying such noncompliance
and the nature and status thereof.  For purposes of this Section 1006, such
compliance shall be determined without regard to any period of grace or
requirement of notice under this Indenture.

          SECTION 1009.  Additional Amounts.  If any Securities of a series
                         ------------------                                
provide for the payment of Additional Amounts, the Company will pay to the
Holder of any Security of such series or any coupon appertaining thereto
Additional Amounts as may be specified as contemplated by Section 301.  Whenever
in this Indenture there is mentioned, in any context except in the case of
Section 502(1), the payment of the principal of or any premium or interest on,
or in respect of, any Security of any series or payment of any related coupon or
the net proceeds received on the sale or exchange of any Security of any series,
such mention shall be deemed to include mention of the payment of Additional
Amounts provided by the terms of such series established pursuant to Section 301
to the extent that, in such context, Additional Amounts are, were or would be
payable in respect thereof pursuant to such terms and express mention of the
payment of Additional Amounts (if applicable) in any provisions hereof shall not
be construed as excluding Additional Amounts in those provisions hereof where
such express mention is not made.

          Except as otherwise specified as contemplated by Section 301, if the
Securities of a series provide for the payment of Additional Amounts, at least
10 days prior to the first Interest Payment Date with respect to that series of
Securities (or if the Securities of that series will not bear interest prior to
Maturity, the first day on which a payment of principal and any premium is
made), and at least 10 days prior to each date of payment of principal and any
premium or interest if there has been any change with respect to the matters set
forth in the below-mentioned Officers' Certifi- 

                                      -50-

 
cate, the Company will furnish the Trustee and the Company's principal Paying
Agent or Paying Agents, if other than the Trustee, with an Officers' Certificate
instructing the Trustee and such Paying Agent or Paying Agents whether such
payment of principal of and any premium or interest on the Securities of that
series shall be made to Holders of Securities of that series or any related
coupons who are not United States persons without withholding for or on account
of any tax, assessment or other governmental charge described in the Securities
of the series. If any such withholding shall be required, then such Officers'
Certificate shall specify by country the amount, if any, required to be withheld
on such payments to such Holders of Securities of that series or related coupons
and the Company will pay to the Trustee or such Paying Agent the Additional
Amounts required by the terms of such Securities. If the Trustee or any Paying
Agent, as the case may be, shall not so receive the above-mentioned certificate,
then the Trustee or such Paying Agent shall be entitled (i) to assume that no
such withholding or deduction is required with respect to any payment of
principal or interest with respect to any Securities of a series or related
coupons until it shall have received a certificate advising otherwise and (ii)
to make all payments of principal and interest with respect to the Securities of
a series or related coupons without withholding or deductions until otherwise 
advised. The Company covenants to indemnify the Trustee and any Paying Agent 
for, and to hold them harmless against, any loss, liability or expense 
reasonably incurred without negligence or bad faith on their part arising out 
of or in connection with actions taken or omitted by any them or in reliance on
any Officers' Certificate furnished pursuant to this Section or in reliance on
the Company's not furnishing such an Officers' Certificate.

          SECTION 1010.  Waiver of Certain Covenants.  The Company may omit in
                         ---------------------------                          
any particular instance to comply with any term, provision or condition set
forth in Sections 1004 and 1005, inclusive, if before or after the time for such
compliance the Holders of at least a majority in principal amount of all
outstanding Securities of such series, by Act of such Holders, 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 term, provision or condition shall remain in full force
and effect.

                                ARTICLE ELEVEN

                           REDEMPTION OF SECURITIES

          SECTION 1101.  Applicability of Article.  Securities of any series
                         ------------------------                           
which are redeemable before their Stated Maturity shall be redeemable in
accordance with their terms and (except as otherwise specified as contemplated
by Section 301 for Securities of any series) in accordance with this Article.

          SECTION 1102.  Election to Redeem; Notice to Trustee.  The election of
                         -------------------------------------                  
the Company to redeem any Securities shall be evidenced by or pursuant to a
Board Resolution.  In case of any reedemption at the election of the Company of
less than all of the Securities of any series, the Company shall, at least 45
days prior to the giving of the notice of redemption in Section 1104 (unless a
shorter notice shall be satisfactory to the Trustee), notify the Trustee of such
Redemption Date and of the principal amount of Securities of such series to be
redeemed.  In the case of any redemption of Securities prior to the expiration
of any restriction on such redemption provided in the terms of such Securities
or elsewhere in this Indenture, the Company shall furnish the Trustee with an
Officers' Certificate evidencing compliance with such restriction.

          SECTION 1103.  Selection by Trustee of Securities to Be Redeemed.  If
                         -------------------------------------------------     
less than all the Securities of any series issued on the same day with the same
terms are to be redeemed, the particular Securities to be redeemed shall be
selected not more than 60 days prior to the Redemption Date by the Trustee, from
the Outstanding Securities of such series issued on such date with the 

                                      -51-

 
same terms not previously called for redemption, by such method as the Trustee
shall deem fair and appropriate and which may provide for the selection for
redemption of portions (equal to the minimum authorized denomination for
Securities of that series or any integral multiple thereof) of the principal
amount of Securities of such series of a denomination larger than the minimum
authorized denomination for Securities of that series.

          The Trustee shall promptly notify the Company and the Security
Registrar (if other than itself) in writing of the Securities selected for
redemption and, in the case of any Securities selected for partial redemption,
the principal amount thereof to be redeemed.

          For all purposes of this Indenture, unless the context otherwise
requires, all provisions relating to the redemption of Securities shall relate,
in the case of any Security redeemed or to be redeemed only in part, to the
portion of the principal amount of such Security which has been or is to be
redeemed.

          SECTION 1104.  Notice of Redemption.  Notice of redemption shall be
                         --------------------                                
given in the manner provided in Section 106, not less than 30 days nor more than
60 days prior to the Redemption Date, unless a shorter period is specified by
the terms of such series established pursuant to Section 301, to each Holder of
Securities to be redeemed, but failure to give such notice in the manner herein
provided to the Holder of any Security designated for redemption as a whole or
in part, or any defect in the notice to any such Holder, shall not affect the
validity of the proceedings for the redemption of any other such Security or
portion thereof.

          Any notice that is mailed to the Holders of Registered Securities in
the manner herein provided shall be conclusively presumed to have been duly
given, whether or not the Holder receives the notice.

          All notices of redemption shall state:

          (1) the Redemption Date,

          (2) the Redemption Price, accrued interest to the Redemption Date
payable as provided in Section 1106, if any, and Additional Amounts, if any,

          (3) if less than all Outstanding Securities of any series are to be
redeemed, the identification (and, in the case of partial redemption, the
principal amount) of the particular Security or Securities to be redeemed,

          (4) in case any Security is to be redeemed in part only, the notice
which relates to such Security shall state that on and after the Redemption
Date, upon surrender of such Security, the holder will receive, without a
charge, a new Security or Securities of authorized denominations for the
principal amount thereof remaining unredeemed,

          (5) that on the Redemption Date the Redemption Price and accrued
interest to the Redemption Date payable as provided in Section 1106, if any,
will become due and payable upon each such Security, or the portion thereof, to
be redeemed and, if applicable, that interest thereon shall cease to accrue on
and after said date,

          (6) the Place or Places of Payment where such Securities, together in
the case of Bearer Securities with all coupons appertaining thereto, if any,
maturing after the Redemption Date, are to be surrendered for payment of the
Redemption Price and accrued interest, if any, or for conversion,

                                      -52-

 
          (7) that, unless otherwise specified in such notice, Bearer Securities
of any series, if any, surrendered for redemption must be accompanied by all
coupons maturing subsequent to the date fixed for redemption or the amount of
any such missing coupon or coupons will be deducted from the Redemption Price,
unless security or indemnity satisfactory to the Company and the Trustee for
such series and any Paying Agent is furnished,

          (8) if Bearer Securities of any series are to be redeemed and any
Registered Securities of such series are not to be redeemed, and if such Bearer
Securities may be exchanged for Registered Securities not subject to redemption
on this Redemption Date pursuant to Section 305 or otherwise, the last date, as
determined by the Company, on which such exchanges may be made,

          (9) the CUSIP number of such Security, if any, and

          (10) if applicable, that a Holder of Securities who desires to convert
Securities for redemption must satisfy the requirements for conversion contained
in such Securities, the then existing conversion price or rate, and the date
and time when the option to convert shall expire.

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

          SECTION 1105.  Deposit of Redemption Price.  At least one Business Day
                         ---------------------------                            
prior to any Redemption Date, the Company shall deposit with the Trustee or with
a Paying Agent (or, if the Company is acting as its own Paying Agent, segregate
and hold in trust as provided in Section 1003) an amount of money in the
currency or currencies, currency unit or units or composite currency or
currencies in which the Securities of such series are payable (except as
otherwise specified pursuant to Section 301 for the Securities of such series)
sufficient to pay on the Redemption Date the Redemption Price of, and (except
if the Redemption Date shall be an Interest Payment Date) accrued interest on,
all the Securities or portions thereof which are to be redeemed on that date.

          SECTION 1106.  Securities Payable on Redemption Date.  Notice of
                         -------------------------------------            
redemption having been given as aforesaid, the Securities so to be redeemed
shall, on the Redemption Date, become due and payable at the Redemption Price
therein specified in the currency or currencies, currency unit or units or
composite currency or currencies in which the Securities of such series are
payable (except as otherwise specified pursuant to Section 301 for the
Securities of such series) (together with accrued interest, if any, to the
Redemption Date), and from and after such date (unless the Company shall default
in the payment of the Redemption Price and accrued interest) such Securities
shall, if the same were interest-bearing, cease to bear interest and the coupons
for such interest appertaining to any Bearer Securities so to be redeemed,
except to the extent provided below, shall be void.  Upon surrender of any such
Security for redemption in accordance with said notice, together with all
coupons, if any, appertaining thereto maturing after the Redemption Date, such
Security shall be paid by the Company at the Redemption Price, together with
accrued interest, if any, to the Redemption Date; provided, however, that
                                                  -----------------      
installments of interest on Bearer Securities whose Stated Maturity is on or
prior to the Redemption Date shall be payable only at an office or agency
located outside the United States (except as otherwise provided in Section 1002)
and, unless otherwise specified as contemplated by Section 301, only upon
presentation and surrender of coupons for such interest; and provided further
                                                             ----------------
that, installments of interest on Registered Securities whose Stated Maturity is
on or prior to the Redemption Date shall be payable to the Holders of such 
Securities, or one or more Predecessor Securities, registered as such at the
close of business on the relevant Record Dates according to their terms and
the provisions of Section 307.

          If any Bearer Security surrendered for redemption shall not be
accompanied by all appurtenant coupons maturing after the Redemption Date, such
Security may be paid after deducting from the Redemption Price an amount equal
to the face amount of all such missing coupons, or the surrender of such missing
coupon or coupons may be waived by the Company and the Trustee if 

                                      -53-

 
there be furnished to them such security or indemnity as they may require to
save each of them and any Paying Agent harmless. If thereafter the Holder of
such Security shall surrender to the Trustee or any Paying Agent any such
missing coupon in respect of which a deduction shall have been made from the
Redemption Price, such Holder shall be entitled to receive the amount so
deducted ; provided, however, that interest represented by coupons shall be
           -----------------
payable only at an office or agency located outside the United States (except
as otherwise provided in Section 1002) and, unless otherwise specified as
contemplated by Section 301, only upon presentation and surrender of those
coupons.

          If any Security called for redemption shall not be so paid upon
surrender thereof for redemption, the principal (and premium or Make-Whole
Amount, if any) shall, until paid, bear interest from the Redemption Date at
the rate borne by the Security.

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


                                ARTICLE TWELVE

                                  GUARANTEES

          SECTION 1201.  Guarantee.  Subject to the provisions of this Article
                         ---------                                            
Twelve, each Guarantor hereby jointly and severally, fully, unconditionally and
irrevocably guarantees to each Holder and to the Trustee on behalf of the
Holders: (i) the due and punctual payment of the principal of, premium, if any,
and accrued interest on each Security, when and as the same shall become due and
payable, whether at maturity, by acceleration or otherwise, the due and punctual
payment of interest on the overdue principal of and interest, if any, on the
Securities, to the extent lawful, and the due and punctual performance of all
other obligations of the Company to the Holders or the Trustee, all in
accordance with the terms of such Security and this Indenture and (ii) in the
case of any extension of time of payment or renewal of any Securities or any of
such other obligations, that the same will be promptly paid in full when due or
performed in accordance with the terms of the extension or renewal, at Stated
Maturity, by acceleration or otherwise (the obligations in subsections (i) and
(ii) hereof being the "Guaranteed Obligations").  Each Guarantor hereby waives
                       ----------------------                                 
diligence, presentment, demand of payment, filing of claims with a court in the
event of merger or bankruptcy of the Company, any right to require a proceeding
first against the Company, the benefit of discussion, protest or notice with
respect to any such Security or the debt evidenced thereby and all demands
whatsoever, and covenants that its Guarantee will not be discharged as to any
such Security except by payment in full of the principal thereof and interest
thereon and as provided in Section 4.01, Section 14.02 and Section 14.03.  The
maturity of the Securities may be accelerated as provided in Article Five for
the purposes of this Article Twelve.  In the event of any declaration of
acceleration of such obligations as provided in Article Five, the Securities
(whether or not due and payable) shall forthwith become due and payable by each
Guarantor jointly and severally, for the purpose of this Article Eleven.  In
addition, without limiting the foregoing provisions, upon the effectiveness of
an acceleration under Article Five, the Trustee shall promptly make a demand for
payment on the Securities under each Guarantee provided for in this Article
Twelve.

          If the Trustee or the Holder of any Security is required by any court
or otherwise to return to the Company or any Guarantor, or any custodian,
receiver, liquidator, trustee, sequestrator 

                                      -54-

 
or other similar official acting in relation to the Company or such Guarantor,
any amount paid to the Trustee or such Holder in respect of a Security, this
Guarantee, to the extent theretofore discharged, shall be reinstated in full
force and effect. Each Guarantor further agrees, to the fullest extent that it
may lawfully do so, that, as between it, on the one hand, and the Holders and
the Trustee, on the other hand, the maturity of the obligations guaranteed
hereby may be accelerated as provided in Article Five hereof for the purposes
of its Guarantee, notwithstanding any stay, injunction or other prohibition
extant under any applicable bankruptcy law preventing such acceleration in
respect of the obligations guaranteed hereby.

          Each Guarantor hereby further agrees that its obligations under this
Indenture and the Securities shall be unconditional, regardless of the validity,
regularity or enforceability of this Indenture or the Securities, the absence of
any action to enforce this Indenture or the Securities, any waiver or consent by
any Holder with respect to any provisions of this Indenture or the Securities,
any modification or amendment of, or supplement to, this Indenture or the
Securities, the recovery of any judgment against the Company or any action to
enforce any such judgment, or any other circumstance that might otherwise
constitute a legal or equitable discharge or defense of a Guarantor.

          Each Guarantor that makes or is required to make any payment in
respect of its Guarantee shall be entitled to seek contribution from the other
Guarantors to the extent permitted by applicable law; provided that each
                                                      --------          
Guarantor agrees that any such claim for contribution that such Guarantor may
have against any other Guarantor shall be subrogated to the prior payment in
full, in cash, of all obligations owed to Holders under or in respect of the
Securities.

          Each Guarantor hereby irrevocably waives any claim or other rights
that it may now or hereafter acquire against the Company that arise from the
existence, payment, performance or enforcement of its obligations under its
Guarantee and this Indenture, including, without limitation, any right of
subrogation, reimbursement, exoneration, contribution, indemnification, any
right to participate in any claim or remedy of the Holders against the Company
or any collateral that any such Holder or the Trustee on behalf of such Holder
hereafter acquires, whether or not such claim, remedy or right arises in equity,
or under contract, statute or common law, including, without limitation, the
right to take or receive from the Company, directly or indirectly, in cash or
other property or by set-off or in any other manner, payment or security on
account of such claim or other rights.  If any amount shall be paid to any
Guarantor in violation of the preceding sentence and the principal of (and
premium, if any) and  interest on the Securities shall not have been paid in
full, such amount shall be deemed to have been paid to such Guarantor for the
benefit of, and held in trust for the benefit of, the Holders, and shall
forthwith be paid to the Trustee for the benefit of the Holders to be credited
and applied upon the principal of (and premium, if any) and  interest on the
Securities.  Each Guarantor acknowledges that it will receive direct and
indirect benefits from the issuance of the Securities pursuant to this Indenture
and that the waivers set forth in this Section 12.01 are knowingly made in
contemplation of such benefits.

          Each Guarantee set forth in this Section 12.01 shall not be valid or
become obligatory for any purpose with respect to a Security until the
certificate of authentication on such Security shall have been signed by or on
behalf of the Trustee.

          SECTION 1202.  Obligations Unconditional.  Subject to Section 12.05,
                         -------------------------                            
nothing contained in this Article Twelve or elsewhere in this Indenture or in
the Securities is intended to or shall impair, as among each Guarantor and the
Holders, the obligation of each Guarantor, which is absolute and unconditional,
upon failure by the Company, to pay to the Holders the principal of (and
premium, if any) and interest on the Securities as and when the same shall
become due and payable in accordance with their terms, or is intended to or
shall affect the relative rights of the Holders and creditors of each Guarantor,
nor shall anything herein or therein prevent any Holder or the Trustee on its
behalf from exercising all remedies otherwise permitted by applicable law upon
default under this Indenture.

                                      -55-

 
          Without limiting the foregoing, nothing contained in this Article
Twelve will restrict the right of the Trustee or the Holders to take any action
to declare the Guarantee to be due and payable prior to the Stated Maturity of
the Securities pursuant to Section 5.02 or to pursue any rights or remedies
hereunder.

          SECTION 1203.  Execution of Guarantee.  To evidence its obligations
                         ----------------------                              
under this Article Twelve, each Guarantor hereby agrees to execute a guarantee
in a form set forth in the supplemental indenture for each series of Securities
guaranteed by the Guarantor, to be endorsed on each Security authenticated and
delivered by the Trustee.  The signature of any officer of a Guarantor on the
Securities may be manual or facsimile.  Each Guarantor hereby agrees that its
Guarantee set forth in this Article Twelve shall remain in full force and effect
notwithstanding any failure to endorse such Guarantee on any series of
Securities.

          SECTION 1204.  Withholding.  All payments made by a Guarantor with
                         -----------                                        
respect to the Guarantees will be made without withholding or deduction for, or
on account of, any present or future taxes, duties, assessments or governmental
charges of whatever nature imposed or levied by or on behalf of any country
(other than the United States) or any political subdivision thereof or any
authority therein or thereof having power to tax, unless the withholding or
deduction of such taxes, duties, assessments or governmental charges is then
required by law.  In the event that any country (other than the United States)
or any political subdivision thereof, or any authority therein or thereof,
imposes any such withholding or deduction on (a) any payments made by a
Guarantor with respect to the Guarantees or (b) any net proceeds on the sale to
or exchange with any Guarantor of the Securities, such Guarantor will pay such
additional amounts as may be necessary in order that the net amounts received in
respect to such payments or sale or exchange by the Holders  or the Trustee, as
the case may be, after such withholding or deduction shall equal the respective
amounts that would have been received in respect of such payments or sale or
exchange in the absence of such withholding or deduction; except that no such
additional amounts shall be payable with respect to any series of Securities
held by or on behalf of a Holder who is liable for such taxes, duties, 
assessments or governmental charges in respect of such Security by reason of his
being a citizen or resident of, or carrying on a business in, the country of
residence of any Guarantor. Notwithstanding the foregoing, a Guarantor making a
payment on the Securities pursuant to the Guarantee shall not be required to pay
any additional amounts if (x) the beneficial holder of a Security received by
certified mail (evidenced by a return receipt signed by such beneficial holder)
(i) written notice from such Guarantor no less than 60 days in advance of making
such payment and (ii) the appropriate forms or instructions necessary to enable
such beneficial holder to certify or document the availability of an exemption
from, or reduction of, the withholding or deduction of such taxes under
applicable law, which such instructions shall clearly specify that additional
amounts under this Section 1204 may not be paid if such forms are not completed
by such beneficial holder, and (y) the Guarantor that would otherwise have to
pay such additional amounts establishes to the satisfaction of the Trustee that
the obligation to pay such additional amounts would not have risen but for the
failure of such beneficial holder to (i) duly complete such forms as were
actually received by such beneficial holder or respond to such instructions and
(ii) provide to such Guarantor such duly completed forms or responses to
instructions. Without prejudice to the survival of any of the agreements of the
Guarantors hereunder, the agreements and obligations of the Guarantors
contained in this Section 1204 shall survive the payment in full of Securities
and all other amounts payable under this Guarantee.

          SECTION 1205.  Limitation of Guarantee.  The Company and each Holder
                         -----------------------                              
by his or her acceptance thereof, hereby confirm that it is the intention of all
such parties that any Guarantee of the Securities executed by a Guarantor under
this Indenture and the terms of a supplemental indenture for any series of
Securities not constitute a fraudulent transfer or conveyance for purposes of
the Bankruptcy Law, the Uniform Fraudulent Conveyance Act or any similar federal
or state law.  To effectuate the foregoing intention, in the event that any such
Guarantee would constitute or result in a violation of any applicable
fraudulent conveyance or similar law of any relevant jurisdiction, the liability
of the Guarantor under such Guarantee shall be reduced to the maximum amount,
after 

                                      -56-

 
giving effect to all other contingent and fixed liabilities of such Guarantor,
permissible under the applicable fraudulent conveyance or similar law.

          SECTION 1206.  Release of Guarantee.  (a) Concurrently with the
                         --------------------                            
payment in full of all of the Securities, the Guarantors shall be released from
and relieved of their obligations under this Article Twelve.  Upon the delivery
by the Company to the Trustee of an Officers' Certificate and, if requested by
the Trustee, an Opinion of Counsel to the effect that the transaction giving
rise to the release of such obligations was made by the Company in accordance
with the provisions of this Indenture, the Trustee shall execute any documents
reasonably required in order to evidence the release of the Guarantors from
their obligations.  If any of the Guaranteed Obligations are revived and
reinstated after the termination of this Guarantee, then all of the obligations
of the Guarantors under this Guarantee shall be revived and reinstated as if
this Guarantee had not been terminated until such time as the Guaranteed
Obligations are again terminated, and the Guarantors shall enter into an
amendment to this Guarantee, reasonably satisfactory to the Trustee, evidencing
such revival and reinstatement.


          (b) Upon the sale or disposition of all the Capital Stock of a
Guarantor (by merger or otherwise) to a Person other than the Company or any
other Guarantor and which sale or disposition is otherwise in compliance with
the terms of this Indenture, such Guarantor shall be deemed released from all
obligations under this Article Twelve; provided, however, that any such
                                       -----------------               
termination upon such sale or disposition shall occur if and only to the extent
that all obligations of such Guarantor under all of its guarantees of, and under
all of its pledges of assets or other security interests which secure,
indebtedness of the Company or any other Guarantor shall also terminate upon
such sale or disposition.  Upon the delivery by the Company to the Trustee of an
Officers' Certificate and, if requested by the Trustee, an Opinion of Counsel
to the effect that the transaction giving rise to the release of such
obligations was made in accordance with the provisions of this Indenture, the
Trustee shall execute any documents reasonably required in order to evidence the
release of such Guarantor from its obligations.  Any Guarantor not so released
remains liable for the full amount of principal of (and premium, if any) and
interest on the Securities as provided in this Article Twelve.


          (c) Nothing contained in this Indenture or in the Securities shall
prevent any consolidation or merger of a Guarantor with or into the Company or
another Guarantor, or shall prevent the transfer of all or substantially all of
the assets of a Guarantor to the Company or another Guarantor.  Upon any such
consolidation, merger, transfer or sale, the Guarantee of such Guarantor shall
no longer have any force of effect.


                               ARTICLE THIRTEEN

                      REPAYMENT AT THE OPTION OF HOLDERS

          SECTION 1301.  Applicability of Article.  Repayment of Securities of
                         ------------------------                             
any series before their Stated Maturity at the option of Holders thereof shall
be made in accordance with the terms of such Securities, if any, and (except as
otherwise specified by the terms of such series established pursuant to Section
301) in accordance with this Article.

          SECTION 1302.  Repayment of Securities.  Securities of any series
                         -----------------------                           
subject to repayment in whole or in part at the option of the Holders thereof
will, unless otherwise provided in the terms of such Securities, be repaid at a
price equal to the principal amount thereof, together with interest, if any,
thereon accrued to the Repayment Date specified in or pursuant to the terms of
such Securities. The Company covenants that at least one Business Day prior to
the Repayment Date it 

                                     -57-

 
will deposit with the Trustee or with a Paying Agent (or, if the Company is
acting as its own Paying Agent, segregate and hold in trust as provided in
Section 1003) an amount of money in the currency or currencies, currency unit or
units or composite currency or currencies in which the Securities of such series
are payable (except as otherwise specified pursuant to Section 301 for the
Securities of such series) sufficient to pay the principal (or, if so provided
by the terms of the Securities of any series, a percentage of the principal) of,
and (except if the Repayment Date shall be an Interest Payment Date) accrued
interest on, all the Securities or portions thereof, as the case may be, to be
repaid on such date.

          SECTION 1303.  Exercise of Option.  Securities of any series subject
                         ------------------                                   
to repayment at the option of the Holders thereof will contain an "Option to
Elect Repayment" form on the reverse of such Securities.  In order for any
Security to be repaid at the option of the Holder, the Trustee must receive at
the Place of Payment there for specified in the terms of such Security (or at
such other place or places of which the Company shall from time to time notify
the Holders of such Securities) not earlier than 60 days nor later than 30 days
prior to the Repayment Date (1) the Security so providing for such repayment
together with the "Option to Elect Repayment" form on the reverse thereof duly
completed by the Holder (or by the Holder's attorney duly authorized in writing)
or (2) a telegram, telex, facsimile transmission or a letter from a member of a
national securities exchange, or the National Association of Securities Dealers,
Inc. ("NASD"), or a commercial bank or trust company in the United States
setting forth the name of the Holder of the Security, the principal amount of
the Security, the principal amount of the Security to be repaid, the CUSIP
number, if any, or a description of the tenor and terms of the Security, a
statement that the option to elect repayment is being exercised thereby and a
guarantee that the Security to be repaid, together with the duly completed form
entitled "Option to Elect Repayment" on the reverse of the Security, will be
received by the Trustee not later than the fifth Business Day after the date of
such telegram, telex, facsimile transmission or letter; provided, however, that
                                                        -----------------      
such telegram, telex, facsimile transmission or letter shall only be effective
if such Security and form duly completed are received by the Trustee by such
fifth Business Day.  If less than the entire principal amount of such Security
is to be repaid in accordance with the terms of such Security, the principal
amount of such Security to be repaid, in increments of the minimum denomination
for Securities of such series, and the denomination or denominations of the
Security or Securities to be issued to the Holder for the portion of the
principal amount of such Security surrendered that is not to be repaid, must be
specified.  The principal amount of any Security providing for repayment at the
option of the Holder thereof may not be repaid in part if, following such
repayment, the unpaid principal amount of such Security would be less than the
minimum authorized denomination of Securities of the series of which such
Security to be repaid is a part.  Except as otherwise may be provided by the
terms of any Security providing for repayment at the option of the Holder
thereof, exercise of the repayment option by the Holder shall be irrevocable
unless waived by the Company.

          SECTION 1304.  When Securities Presented for Repayment Become Due and
                         ------------------------------------------------------
Payable.  If Securities of any series provide repayment at the option of the
- -------                                                                     
Holders thereof shall have been surrendered as provided in this Article and as
provided by or pursuant to the terms of such Securities, such Securities or the
portion thereof, as the case may be, to be repaid shall become due and payable
and shall be paid by the Company on the Repayment Date therein specified, and on
and after such Repayment Date (unless the Company shall default in the payment
of such Securities on such Repayment Date) such Securities shall, if the same
were interest-bearing, cease to bear interest and the coupons for such interest
appertaining to any Bearer Securities so to be repaid, except to the extent
provided below, shall be void.  Upon surrender of any such Security for
repayment in accordance with such provisions, together with coupons, if any,
appertaining thereto maturing after the Repayment Date, the principal amount of
such Security so to be repaid paid by the Company, together with accrued
interest, if any, Repayment Date; provided, however, that coupons whose Stated
                                  -----------------                           
Maturity is on or prior to the Repayment Date shall be payable at an office or
agency located outside the United States (except as otherwise provided in
Section 1002) and, unless otherwise specified pursuant to Section 301, only
upon presentation and surrender of such coupons; and provided further 
                                                     -------- -------         

                                     -58-

 
that, in the case of Registered Securities, installments of interest, if any,
whose Stated Maturity is on or prior to the Repayment Date shall be payable (but
with interest thereon, unless the Company shall default in the payment thereof)
to the Holders of such Securities, or one or more Predecessor Securities,
registered as such at the close of business relevant Record Dates according to
their terms and the provisions of Section 307.

          If any Bearer Security surrendered for repayment shall not be
accompanied by all appurtenant coupons maturing after the Repayment Date, such
Security may be paid after deducting from the amount payable therefor as
provided in Section 1302 an amount equal to the face amount of all such missing
coupons, or the surrender of such missing coupon or coupons may be waived by the
Company and the Trustee if there be furnished to it such security or indemnity
as they may require to save it and any Paying Agent harmless.  If thereafter the
Holder of such Security shall surrender to the Trustee or any Paying Agent any
such missing coupon in respect of  which a deduction shall have been made as
provided in the preceding sentence, such Holder shall be entitled to receive the
amount so deducted; provided, however, that interest represented by coupons
                    -----------------                                      
shall be payable only at an office or agency located outside the United States
(except as otherwise provided in Section 1002) and, unless otherwise specified
as contemplated by Section 301, only presentation and surrender of those
coupons.

          If the principal amount of any Security surrendered for repayment
shall not be so repaid upon surrender thereof, such principal amount (together
with interest, if any, thereon accrued to such Repayment Date) shall, until
paid, bear interest from the Repayment Date at the rate of interest or Yield to
Maturity (in the case of Original Issue Discount Securities) set forth in such
Security.

          SECTION 1305.  Securities Repaid in Part.  Upon surrender of any
                         -------------------------                        
Registered Security which is to be repaid in part only, the Company shall
execute and the Trustee shall authenticate and deliver to the Holder of such
Security, without service charge and at the expense of the Company, a new
Registered Security or Securities of the same series, of any authorized
denomination specified by the Holder, in an aggregate principal amount equal to
and in exchange for the portion of the principal of such Security so surrendered
which is not to be repaid.


                               ARTICLE FOURTEEN

                      DEFEASANCE AND COVENANT DEFEASANCE

          SECTION 1401.  Applicability of Article; Company's Option to Effect
                         ----------------------------------------------------
Defeasance or Covenant Defeasance.  If, pursuant to Section 301, provision is
- ---------------------------------                                            
made for either or both of (a) defeasance of the Securities of or within a
series under Section 1402 or (b) covenant defeasance of the Securities of or
within a series under Section 1403, then the provisions of such Section or
Sections, as the case may be, together with the other provisions of this Article
(with such modifications thereto as may be specified pursuant to Section 301
with respect to any Securities), shall be applicable to such Securities and any
coupons appertaining thereto, and the Company may at its option by Board
Resolution, at any time, with respect to such Securities and any coupons
appertaining thereto, elect to have Section 1402 (if applicable) or Section 1403
(if applicable) be applied to such Outstanding Securities and any coupons
appertaining thereto upon compliance with the conditions set forth below in this
Article.

          SECTION 1402.  Defeasance and Discharge.  Upon the Company's exercise
                         ------------------------                              
of the above option applicable to this Section with respect to any Securities of
or within a series, the Company and the Guarantors shall be deemed to have been
discharged from their obligations with respect to such Outstanding Securities
and any coupons appertaining thereto on the date the conditions set forth in
Section 1404 are satisfied (hereinafter, "defeasance").  For this purpose, such
defea-

                                     -59-

 
sance means that the Company shall be deemed to have paid and discharged the
entire indebtedness represented by such Outstanding Securities and any coupons
appertaining thereto, which shall thereafter be deemed to be "Outstanding" only
for the purposes of Section 1405 and the other Sections of this Indenture
referred to in clauses (A) and (B) below, and to have satisfied all of its other
obligations under such Securities and any coupons appertaining thereto and this
Indenture insofar as such Securities and any coupons appertaining thereto are
concerned (and the Trustee, at the expense of the Company, shall execute proper
instruments acknowledging the same), except for the following which shall
survive until otherwise terminated or discharged hereunder: (A) the rights of
Holders of such Outstanding Securities and any coupons appertaining thereto to
receive, solely from the trust fund described in Section 1404 and as more fully
set forth in such Section, payments in respect of the principal of (and
premium, if any) and interest, if any, on such Securities and any coupons
appertaining thereto when such payments are due, (B) the Company's obligations
with respect to such Securities under Sections 305, 306, 1002 and 1003 and with
respect to the payment of Additional Amounts, if any, on such Securities as
contemplated by Section 1007, (C) the rights, powers, trusts, duties and
immunities of the Trustee hereunder and (D) this Article. Subject to compliance
with this Article Fourteen, the Company may exercise its option under this
Section notwithstanding the prior exercise of its option under Section 1403 with
respect to such Securities and any coupons appertaining thereto.

          SECTION 1403.  Covenant Defeasance.  Upon the Company's exercise of
                         -------------------                                 
the above option applicable to this Section with respect to any Securities of or
within a series, the Company and the Guarantors shall be released from their
obligations under Sections 1004 and 1005, inclusive and, if specified pursuant
to Section 301, their obligations under any other covenant, with respect to such
Outstanding Securities and coupons appertaining thereto on and after the date
the conditions set forth in Section 1404 are satisfied (hereinafter, "covenant
defeasance"), and such Securities and any coupons appertaining thereto shall
thereafter be deemed to be not "Outstanding" for the purposes of any direction,
waiver, consent or declaration or Act of Holders (and the consequences of any
thereof) in connection with Sections 1004 and 1005, inclusive, or such other
covenant, but shall continue to be deemed "Outstanding" for all other purposes
hereunder.  For this purpose, such covenant defeasance means that, with respect
to such Outstanding Securities and any coupons appertaining thereto, the Company
and the Guarantors may omit to comply with and shall have no liability in
respect of any term, condition or limitation set forth in any such Section or
such other covenant, whether directly or indirectly, by reason of any reference
elsewhere herein to any such Section or such other covenant or by reason of
reference in any Section or such other covenant to any other provision herein or
in any other document and such omission to comply shall not constitute a default
or an Event of Default under Section 501(3) or 501(7) otherwise, as the case may
be, but, except as specified above, remainder of this Indenture and such
Securities and any coupons appertaining thereto shall be unaffected thereby.

          SECTION 1404.  Conditions to Defeasance or Covenant Defeasance.  The
                         -----------------------------------------------

thereto:

          (a) The Company shall irrevocably have deposited or caused to be

appertaining thereto are then specified as payable at Stated Maturity) which
through the scheduled payment of principal and interest in respect thereof in
accordance with the terms will provide, not later than one day before the due
date of any 

                                     -60-

 
payment of principal of (and premium or Make-Whole Amount, if any) and interest,
if any, on such Securities and any coupons appertaining thereto, money in an
amount, or (3) a combination thereof, any case, in an amount, sufficient,
without consideration of any reinvestment of such principal and interest, in the
opinion of a nationally recognized firm of independent public accountants
expressed in a written certification thereof delivered the Trustee, to pay and
discharge, and which shall be applied by the Trustee (or other qualifying
trustee) to pay and discharge, the principal of (and premium or Make-Whole
Amount, if any) and interest, if any, on such Outstanding Securities and any
coupons, appertaining thereto on the Stated Maturity of such principal or
installment of principal or interest or analogous payments applicable to such
Outstanding Securities and any coupons appertaining thereto on the day on which
such payments are due and payable in accordance with the terms of this Indenture
and of such Securities and any coupons appertaining thereto.

          (b) Such defeasance or covenant defeasance shall not result in a
breach or violation of, or constitute a default under, this Indenture or any
other material agreement or instrument to which the Company is a party or by
which it is bound.

          (c) No Event of Default or event which with notice or lapse of time or
both would become an Event of Default with respect to such Securities and any
coupons appertaining thereto shall have occurred and be continuing on the date
of such deposit or, insofar as Sections 501(6) and 501(7) are concerned, at any
time during the period ending on the 91st day after the date of such deposit
(it being understood that this condition shall not be deemed satisfied until the
expiration of such period).

          (d) In the case of an election under Section 1402, the Company shall
have delivered to the Trustee an Opinion of Counsel stating that (i) the
Company has received from, or there has been published by, the Internal Revenue
Service a ruling, or (ii) since the date of execution of this Indenture, there
has been a change in the applicable Federal income tax law, in either case to
the effect that, and based thereon such opinion shall confirm that, the Holders
of such Outstanding Securities and any coupons appertaining thereto will not
recognize income, gain or loss for Federal income tax purposes as a result of
such defeasance and will be subject to Federal income tax on the same amounts,
in the same manner and at the same times as would have been the case if such
defeasance had not occurred.

          (e) In the case of an election under Section 1403, the Company shall
have delivered to the Trustee an Opinion of Counsel to the effect that the
Holders of such Outstanding Securities and any coupons appertaining thereto
will not recognize income, gain or loss for Federal income tax purposes as a
result of such covenant defeasance and will be subject to Federal income tax on
the same amounts, in the same manner and at the same times as would have been
the case if such covenant defeasance had not occurred.

          (f) The Company shall have delivered to the Trustee an Officers'
Certificate and an Opinion of Counsel, each stating that all conditions
precedent to the defeasance under Section 1402 or the covenant defeasance under
Section 1403 (as the case may be) have been complied with and an Opinion of
Counsel to the effect that either (i) as a result of a deposit pursuant to
subsection (a) above and the related exercise of the Company's option under
Section 1402 or Section 1403 (as the case may be), registration is not required
under the Investment Company Act of 1940, as amended, by the Company with
respect to the trust funds representing such deposit or by the Trustee for such
trust funds or (ii) all necessary registrations under said Act have been
effected.

          (g) Notwithstanding any other provisions of this Section, such
defeasance or covenant defeasance shall be effected in compliance with any
additional or substitute terms, conditions or limitations which may be imposed
on the Company in connection therewith pursuant to Section 301.

          SECTION 1405.  Deposited Money and Government Obligations to Be Held
                         -----------------------------------------------------
in Trust; Other Miscellaneous Provisions.  Subject to the provisions of the last
- ----------------------------------------                                        
paragraph of Section 1003, all money and Government Obligations (or other
property as may be provided pursuant to Section 301) (including the proceeds
thereof) deposited with the Trustee (or other qualifying trustee, collectively
for purposes of this Section 1405, the "Trustee") pursuant to Section 1404 in
respect of any Outstanding Securities of any series and any coupons
appertaining thereto shall be held in trust and applied by the Trustee, in
accordance with the provisions of such Securities and any coupons appertaining
thereto and this Indenture, to the payment, either directly or through any
Paying Agent as the Trustee may determine, to the Holders of such Securities
and any coupons appertaining thereto of all sums due and to become due thereon
in respect of principal (and premium, if any) and interest, but such money need
not be segregated from other funds except to the extent required by law.

          Unless otherwise specified with respect to any Security pursuant to
Section 301, if, after a deposit referred to in Section 1404(a) has been made,
(a) the Holder of a Security in respect of which such deposit was made is
entitled to, and does, elect pursuant to Section 301 or the terms of such
Security to receive payment in a currency or currency unit other than that in
which the deposit pursuant to Section 1404(a) has been made in respect of such
Security, or (b) a Conversion Event occurs in respect of the currency or
currency unit in which the deposit pursuant to Section 1404(a) has been made,
the indebtedness represented by such Security and any coupons appertaining
thereto shall be deemed to have been, and will be, fully discharged and
satisfied through the payment of the principal of (and premium or Make-Whole
Amount, if any), and interest, if any, on such Security as the same becomes due
out of the proceeds yielded by converting (from time to time as specified below
in the case of any such election) the amount or other property deposited in
respect of such Security into the currency or currency unit in which such
Security becomes payable as a result of such election or Conversion Event based
on the applicable market exchange rate for such currency or currency unit in
effect on the second Business Day prior to each payment date, except, with
respect to a Conversion Event, for such currency or currency unit in effect (as
nearly as feasible) at the time of the Conversion Event.

          The Company shall pay and indemnify the Trustee against any tax, fee
or other charge imposed on or assessed against the Government Obligations
deposited pursuant to Section 1404 or the principal and interest received in
respect thereof other than any such tax, fee or other charge which by law is for
the account of the Holders of such Outstanding Securities and any coupons
appertaining thereto.

          Anything in this Article to the contrary notwithstanding, subject to
Section 606, the Trustee shall deliver or pay to the Company from time to time
upon the Company Request any money or Government Obligations (or other property
and any proceeds therefrom) held by it as provided in Section 1404 which, in
the opinion of a nationally recognized firm of independent public accountants
expressed in a written certification thereof delivered to the Trustee, are in
excess of the amount thereof which would then be required to be deposited to
effect a defeasance or covenant defeasance, as applicable, in accordance with
this Article.

                                     -62-

 
                                ARTICLE SIXTEEN

                                 SUBORDINATION

          SECTION 1601.  Agreement to Subordinate.   The Company agrees, and
                         -------------------------                          
each Holder by accepting a Security agrees, that the indebtedness evidenced by
the Securities is subordinated in right of payment, to the extent and in the
manner provided in this Article, to the prior payment in full of all Senior Debt
and that the subordination is for the benefit of the holders of Senior Debt.

          SECTION 1602.  Liquidation; Dissolution; Bankruptcy.   Upon any
                         -------------------------------------           
distribution to creditors of the Company in a liquidation or dissolution of the
Company or in a bankruptcy, reorganization, insolvency, receivership or similar
proceeding relating to the Company or its property:

              (1) Holders of Senior Debt shall be entitled to receive payment in
          full in cash of the principal of (and premium or Make-Whole Amount, if
          any) and interest (including interest accruing after the commencement
          of any such proceeding) to the date of payment on the Senior Debt
          before Holders shall be entitled to receive any payment of principal
          of or interest on Securities;

              (2) Until the Senior Debt is paid in full in cash, any
          distribution to which Holders would be entitled but for this Article
          shall be made to holders of Senior Debt as their interests may appear,
          except that Holders may receive securities that are subordinated to
          Senior Debt to at least the same extent as the Securities; and

              (3) the Trustee is entitled to rely upon an order or decree of a
          court of competent jurisdiction or a certificate of a bankruptcy
          trustee or other similar official for the purpose of ascertaining the
          persons entitled to participate in such distribution, the holders of
          Senior Debt and other Company debt, the amount thereof or payable
          thereon and all other pertinent facts relating to the Trustee's
          obligations under this Article Sixteen.

          SECTION 1603.  Default on Senior Debt.   The Company may not pay
                         -----------------------                          
principal of or interest on the Securities and may not acquire any Securities
for cash or property other than capital stock of the Company if:

              (1) a default on Senior Debt occurs and is continuing that permits
          Holders of such Senior Debt to accelerate its maturity, and

              (2) the default is the subject of judicial proceedings or the
          Company receives a notice of the default from a person who may give
          it pursuant to Section 1611.  If the Company receives any such notice,
          a similar notice received within nine months thereafter relating to
          the same default on the same issue of Senior Debt shall not be
          effective for purposes of this Section.

          The Company may resume payments on the Securities and may acquire them
when:

          (a) the default is cured or waived, or

          (b) 120 days pass after the notice is given if the default is not the
subject of judicial proceedings.

if this Article otherwise permits the payment or acquisition at that time.

                                     -63-

 
          SECTION 1604.  Acceleration of Securities.   If payment of the
                         --------------------------                     
Securities is accelerated because of an Event of Default, the Company shall
promptly notify Holders of Senior Debt of the acceleration.  The Company may pay
the Securities when 120 days pass after the acceleration occurs if this Article
permits the payment at that time.

          SECTION 1605.  When Distribution Must Be Paid Over.   If a
                         ------------------------------------       
distribution is made to Holders that because of this Article should not have
been made to them, the Holders who receive the distribution shall hold it in
trust for Holders of Senior Debt and pay it over to them as their interests may
appear.

          SECTION 1606.  Notice by Company.   The Company shall promptly notify
                         ------------------                                    
the Trustee and any Paying Agent of any facts known to them that would cause a
payment of principal of or interest on Securities to violate this Article.

          SECTION 1607.  Subrogation.   After all Senior Debt is paid in full
                         ------------                                        
and until the Securities are paid in full, Holders shall be subrogated to the
rights of Holders of Senior Debt to receive distributions applicable to Senior
Debt to the extent that distributions otherwise payable to the Holders have been
applied to the payment of Senior Debt.  A distribution made under this Article
to Holders of Senior Debt which otherwise would have been made to Holders is
not, as between the Company and Holders, a payment by the Company on Senior
Debt.

          SECTION 1608.  Relative Rights.   This Article defines the relative
                         ----------------                                    
rights of Holders and Holders of Senior Debt.  Nothing in this Indenture shall:

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

               (2) affect the relative rights of Holders and creditors of the
          Company other than Holders of Senior Debt; or

               (3) prevent the Trustee or any Holder from exercising its
          available remedies upon an Event of Default, subject to the rights of
          Holders of Senior Debt to receive distributions otherwise payable to
          Holders.

          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 a default.

          SECTION 1609.  Subordination May Not Be Impaired By Company.   No
                         ---------------------------------------------     
right of any Holder of Senior Debt 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 1610.  Distribution or Notice to Representative.   Whenever a
                         ----------------------------------------              
distribution is to be made or a notice given to Holders of Senior Debt, the
distribution may be made and the notice given to their Representative.

          SECTION 1611.  Rights of Trustee and Paying Agent.   The Trustee or
                         ----------------------------------                  
any Paying Agent may continue to make payments on the Securities until it
receives written notice of facts that would cause a payment of principal of or
interest on the Securities to violate the Article.  Only the Company, a
Representative or a Holder of an issue of Senior Debt that has no Representative
may give the written notice.

                                      -64-

 
          The Trustee has no fiduciary duty to the Holders of Senior Debt other
than as created under this Indenture.  The Trustee in its individual or any
other capacity may hold Senior Debt with the same rights it would have if it
were not Trustee.

          The Company's obligation to pay, and the Company's payment of, the
Trustee's fees pursuant to Section 606 are excluded from the operation of this
Article Sixteen.

          This Indenture may be executed in any number of counterparts, each of
which so executed shall be deemed to be an original, but all such counterparts
