such Securities or (b) U.S. Government Obligations as contemplated by Section
4.02 in the necessary amount have been theretofore deposited with the Trustee
(or another trustee satisfying the requirements of Section 6.09) in trust for
the Holders of such Securities in accordance with Section 4.03; provided that,
if such Securities are to be redeemed, notice of such redemption has been duly
given pursuant to this Indenture or provision therefor satisfactory to the

     (iv) Securities which have been paid pursuant to Section 3.06 or in
exchange for or in lieu of which other Securities have been authenticated and
delivered pursuant to this Indenture, other than any such Securities in respect
of which there shall have been presented to the Trustee proof satisfactory to it
that such Securities are held by a bona fide purchaser in whose hands such
Securities are valid obligations of the Company;

provided, however, that in determining whether the Holders of the requisite
principal amount of the Outstanding Securities have given any request, demand,
authorization, direction, notice, consent, waiver or other action hereunder as
of any date (A) the principal amount of an Original Issue Discount Security
which shall be deemed to be Outstanding shall be the amount of the principal
thereof which would be due and payable as of such date upon acceleration of the
Maturity thereof to such date pursuant to Section 5.02, (B) if, as of such date,
the principal amount payable at the Stated Maturity of a Security is not
determinable, the principal amount of such Security which shall be deemed to be
Outstanding shall be the amount as specified or determined as contemplated by
Section 3.01, (C) the principal amount of a Security denominated in one or more
foreign currencies or currency units which shall be deemed to be Outstanding
shall be the U.S. dollar equivalent, determined as of such date in the manner
provided as contemplated by Section 3.01, of the principal amount of such
Security (or, in the case of a Security described in clause (A) or (B) of this
paragraph, of the amount determined as provided in such clause), and (D)
Securities owned by the Company or any other obligor upon the Securities or any
Subsidiary of the Company or of such other obligor shall be disregarded and
deemed not to be Outstanding, except that, in determining whether the Trustee
shall be protected in relying upon any such request, demand, authorization,
direction, notice, consent, waiver or other action, only Securities which a
Responsible Officer of the Trustee actually knows to be so owned shall be so
disregarded. Securities so owned which have been pledged in good faith may be
regarded as Outstanding if the pledgee establishes to the satisfaction of the

the pledgee is not the Company or any other obligor upon the Securities or any

provided for in this Indenture shall include

     SECTION 1.03. Form of Documents Delivered to Trustee

     In any case where several matters are required to be certified by, or

representations by, counsel, unless such officer knows, or in the exercise of
reasonable care should know, that the certificate or opinion or representations
with respect to the matters upon which his certificate or opinion is based are
erroneous. Any such certificate or Opinion of Counsel may be based, insofar as
it relates to factual matters, upon a certificate or opinion of, or
representations by, an officer or officers of the Company stating that the
information with respect to such factual matters is in the possession of the
Company, unless such counsel knows, or in the exercise of reasonable care should
know, that the certificate or opinion or representations with respect to such
matters are erroneous.

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

     SECTION 1.04. 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 may
be embodied in and evidenced by one or more instruments of substantially similar
tenor signed by such Holders in person or by an agent duly appointed in writing;
and, except as herein otherwise expressly provided, such action shall become
effective when such instrument or instruments are delivered to the Trustee and,
where it is hereby expressly required, to the Company. If any Securities are
denominated in coin or currency other than that of the United States, then for
the purposes of determining whether the Holders of the requisite principal
amount of Securities have taken any action with respect to the Securities of
more than one series as herein described, the principal amount of such
Securities shall be deemed to be that amount of United States dollars that could
be obtained for such principal amount on the basis of the spot rate of exchange
into United States dollars for the currency in which such Securities are
denominated (as evidenced to the Trustee by an Officers' Certificate) as of the
date the taking of such action by the Holders of such requisite principal amount
is evidenced to the Trustee as provided in the immediately preceding sentence.
Such instrument or instruments (and the action embodied therein and evidenced
thereby) are herein sometimes referred to as the "Act" of the Holders signing
such instrument or instruments. Proof of execution of any such instrument or of
a writing appointing any such agent shall be sufficient for any purpose of this
Indenture and (subject to Section 6.01) conclusive in favor of the Trustee and
the Company, if made in the manner provided in this Section.


                                       11

<PAGE>

     (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 manner which the Trustee deems sufficient.

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

     (d) 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 or the Company in
reliance thereon, whether or not notation of such action is made upon such
Security.

     SECTION 1.05. 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,

     (a) 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, Attention: Corporate Trust
Administration, or at any other address previously furnished in writing to the
Company and the Holders by the Trustee; or

     (b) 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 21001 Van Born Road, Taylor, Michigan 48180 or at any other address
previously furnished in writing to the Trustee by the Company.

     SECTION 1.06. Notice to Holders; Waiver

     Where this Indenture provides for notice to Holders of any event, such
notice shall be sufficiently given (unless otherwise herein expressly provided)
if in writing and mailed, first-class postage prepaid, to each Holder affected
by such


                                       12

<PAGE>

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 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. 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.

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

     SECTION 1.07. Conflict with Trust Indenture Act

     If any provision hereof limits, qualifies or conflicts with another
provision hereof which is required to be included in this Indenture by any of
the provisions of the Trust Indenture Act, such required provision shall
control.

     SECTION 1.08. Effect of Headings and Table of Contents

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

     SECTION 1.09. Successors and Assigns

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

     SECTION 1.10. Separability Clause

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

     SECTION 1.11. Benefits of Indenture

     Nothing in this Indenture or in the Securities, express or implied, shall
give to any Person, other than the Parties hereto, any Authenticating Agent, any
Paying Agent, any Securities Registrar and their successors hereunder and the


                                       13

<PAGE>

Holders, any benefit or any legal or equitable right, remedy or claim under this
Indenture.

     SECTION 1.12. Governing Law

     This Indenture and the Securities shall be governed by and construed in
accordance with the laws of the State of New York without regard to any
conflicts of laws principles therein.

     SECTION 1.13. Legal Holidays

     In any case where any Interest Payment Date, Redemption Date or Stated
Maturity of any Security shall not be a Business Day at any Place of Payment,
then, unless otherwise specified in such Security, payment of interest or
principal (and premium, if any) need not be made at such Place of Payment on
such date, but may be made on the next succeeding Business Day at such Place of
Payment with the same force and effect as if made on the Interest Payment Date
or Redemption Date, or at the Stated Maturity, provided that no interest shall
accrue for the period from and after such Interest Payment Date, Redemption Date
or Stated Maturity, as the case may be.

     SECTION 1.14. Counterparts

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

                                    ARTICLE 2
                                 SECURITY FORMS

     SECTION 2.01. Forms Generally

     The Securities of each series shall be in substantially the form set forth
in Exhibit A, or in such other form as shall be established by or pursuant to a
Board Resolution or in one or more indentures supplemental hereto, in each case
with such appropriate insertions, omissions, substitutions and other variations
as are required or permitted by this Indenture, and may have such letters,
numbers or other marks of identification and such legends or endorsements placed
thereon as may be required to comply with any law or any rules or regulations
pursuant thereto, or with the rules of any securities exchange or to conform to
general usage, all as may consistently herewith be determined by the officers
executing


                                       14

<PAGE>

such Securities, as evidenced by their execution of the Securities. If the form
of Securities of any series is established by action taken pursuant to a Board
Resolution, a copy of an appropriate record of such action shall be certified by
the Secretary or an Assistant Secretary of the Company and delivered to the
Trustee at or prior to the delivery of the Company Order contemplated by Section
3.03 for the authentication and delivery of such Securities.

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

     SECTION 2.02. Securities in Permanent Global Form

     If the Company shall establish pursuant to Section 3.01 that the Securities
of a series are to be issued in whole or in part in permanent global form, then
notwithstanding Section 3.01(h) and the provisions of Section 3.02, 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 from time to time endorsed thereon and that the
aggregate amount of Outstanding Securities represented thereby may from time to
time be reduced or increased to reflect exchanges. Any endorsement of a Security
in permanent 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 or the Security Registrar in such manner and upon instructions given by
such Person or Persons as shall be specified in such Security in permanent
global form or in the Company Order to be delivered to the Trustee pursuant to
Section 3.03 or Section 3.04. Subject to the provisions of Section 3.03 and, if
applicable, Section 3.04, the Trustee or the Security Registrar shall deliver
and redeliver any Security in permanent global form in the manner and upon
instructions given by the Person or Persons specified in such Security or in the
applicable Company Order. If a Company Order pursuant to Section 3.03 or 3.04
has been, or simultaneously is, delivered, any instructions by the Company with
respect to endorsement or delivery or redelivery of a global Security shall be
in writing but need not comply with Section 1.02 and need not be accompanied by
an Officers' Certificate or an Opinion of Counsel, provided that the form of
permanent global Security to be endorsed, delivered or redelivered has
previously been covered by an Opinion of Counsel.

     The provisions of the last sentence of Section 3.03 shall only apply to any
Security represented by a Security in permanent global form if such Security was
never issued and sold by the Company and the Company delivers to the Trustee or
the Security Registrar the Security in permanent global form together with
written


                                       15

<PAGE>

instructions (which need not comply with Section 1.02 and need not be
accompanied by an Officers' Certificate or 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
3.03.

     Unless otherwise specified as contemplated by Section 3.01 for the
Securities evidenced thereby, every Security in permanent global form
authenticated and delivered hereunder shall bear a legend in substantially the
following form:

     UNLESS THIS CERTIFICATE IS PRESENTED BY AN AUTHORIZED REPRESENTATIVE OF THE
DEPOSITARY TO THE ISSUER OR ITS AGENT FOR REGISTRATION OF TRANSFER, EXCHANGE OR
PAYMENT, AND ANY CERTIFICATE ISSUED IS REGISTERED IN THE NAME OF THE DEPOSITARY
OR ITS NOMINEE AND ANY PAYMENT IS MADE TO THE DEPOSITARY OR ITS NOMINEE, ANY
TRANSFER, PLEDGE OR OTHER USE HEREOF FOR VALUE OR OTHERWISE BY OR TO ANY PERSON
IS WRONGFUL SINCE THE REGISTERED OWNER HEREOF HAS AN INTEREST HEREIN.

3.05, 3.06, 9.06 or 11.07 and except for any Securities which, pursuant to

     SECTION 3.02. Denominations

     The Securities of each series shall be issuable in registered form without
coupons and, except for any Security issuable in permanent global form, in such
denominations as shall be specified in accordance with Section 3.01. In the

                                       19

<PAGE>

Securities of such series, other than a Security issuable in permanent global
form, shall be issuable in denominations of $1,000 and any multiple thereof.

     SECTION 3.03. Execution, Authentication, Delivery and Dating

     The Securities shall be executed on behalf of the Company by its Chairman
of the Board, its President, one of its Vice Presidents or its Treasurer,
attested by its Secretary or one of its Assistant Secretaries. The signature of
any of these officers on the Securities may be manual or facsimile.

     Securities bearing the manual or facsimile signatures of individuals who
were at any time the proper officers of the Company shall bind the Company,
notwithstanding that such individuals or any of them have ceased to hold such
offices prior to the authentication and delivery of such Securities or did not
hold such offices at the date of such Securities.

     At any time and from time to time after the execution and delivery of this
Indenture, the Company may deliver Securities of any series executed by the
Company to the Trustee for authentication, together with the applicable
documents referred to below in this Section, and the Trustee shall thereupon
authenticate and deliver such Securities to or upon the order of the Company
(contained in the Company Order referred to below in this Section) or pursuant
to such procedures acceptable to the Trustee and to such recipients as may be
specified from time to time by a Company Order. The maturity date, original
issue date, interest rate and any other terms of the Securities of such series
shall be determined by or pursuant to such Company Order and procedures. If
provided for in such procedures, such Company Order may authorize authentication
and delivery pursuant to oral instructions from the Company or its duly
authorized agent, which instructions shall be promptly confirmed in writing. In
authenticating such Securities, and accepting the additional responsibilities
under this Indenture in relation to such Securities, the Trustee shall be
entitled to receive (in the case of subparagraphs 3.03(ii), 3.03(iii) and
3.03(iv) below, only at or before the time of the first request of the Company
to the Trustee to authenticate Securities of such series) and (subject to
Section 6.01) shall be fully protected in relying upon, unless and until such
documents have been superseded or revoked:

          (i) a Company Order requesting such authentication and setting forth
     delivery instructions if the Securities are not to be delivered to the
     Company, provided that, with respect to Securities of a series subject to a
     Periodic Offering, (a) such Company Order may be delivered by the Company
     to the Trustee prior to the delivery to the Trustee of such Securities for
     authentication and delivery, (b) the Trustee shall authenticate and deliver
     Securities of such series for original issue from


                                       20

<PAGE>

     time to time, in an aggregate principal amount not exceeding the aggregate
     principal amount, if any, established for such series, pursuant to a
     Company Order or pursuant to procedures acceptable to the Trustee as may be
     specified from time to time by a Company Order, (c) the maturity date or
     dates, original issue date or dates, interest rate or rates and any other
     terms of Securities of such series shall be determined by a Company Order
     or pursuant to such procedures and (d) if provided for in such procedures,
     such Company Order may authorize authentication and delivery pursuant to
     oral or electronic instructions from the Company or its duly authorized
     agent or agents, which oral instructions shall be promptly confirmed in
     writing;

          (ii) any Board Resolution, Officers' Certificate and/or executed
     supplemental indenture referred to in Sections 2.01 and 3.01 by or pursuant
     to which the forms and terms of the Securities were established;

          (iii) an Officers' Certificate setting forth the form or forms and (to
     the extent established) the terms of the Securities, stating that the form
     or forms and any such terms of the Securities have been established
     pursuant to Sections 2.01 and 3.01 and comply with this Indenture, and
     covering such other matters as the Trustee may reasonably request; and

          (iv) At the option of the Company, either an Opinion of Counsel, or a
     letter addressed to the Trustee permitting to it rely on an Opinion of
     Counsel, substantially to the effect that:

               (A) the forms of the Securities have been duly authorized and
          established in conformity with the provisions of this Indenture;

               (B) if all of the terms of the Securities of such series have
          been established, the terms of the Securities have been duly
          authorized by the Company and established in conformity with the
          provisions of this Indenture, and, in the case of all other offerings,
          certain terms of the Securities have been established pursuant to a
          Board Resolution, an Officers' Certificate or a supplemental indenture
          in accordance with this Indenture, and when such other terms as are to
          be established pursuant to procedures set forth in a Company Order
          shall have been established, all such terms will have been duly
          authorized by the Company and will have been established in conformity
          with the provisions of this Indenture;

               (C) when the Securities have been executed by the Company and
          authenticated by the Trustee in accordance with the


                                       21

<PAGE>

          provisions of this Indenture and delivered to and duly paid for by the
          purchasers thereof, they will have been duly issued under this
          Indenture and will be valid and legally binding obligations of the
          Company, enforceable in accordance with their respective terms, and
          will be entitled to the benefits of this Indenture; and

               (D) the execution and delivery by the Company of, and the
          performance by the Company of its obligations under, the Securities
          will not contravene any provision of applicable law or the certificate
          of incorporation or by-laws of the Company or, to the best of such
          counsel's knowledge, any agreement or other instrument binding upon
          the Company or any of its subsidiaries that is material to the Company
          and its subsidiaries, considered as one enterprise, or, to the best of
          such counsel's knowledge, any judgment, order or decree of any
          governmental body, agency or court having jurisdiction over the
          Company or any subsidiary, and no consent, approval or authorization
          of any governmental body or agency is required for the performance by
          the Company of its obligations under the Securities, except such as
          are specified and have been obtained and such as may be required by
          the securities or blue sky laws of the various states in connection
          with the offer and sale of the Securities.

     In rendering such opinions, such counsel may qualify any opinions as to
enforceability by stating that such enforceability may be limited by bankruptcy,
insolvency, reorganization, liquidation, moratorium and other similar laws
affecting the rights and remedies of creditors and is subject to general
principles of equity (regardless of whether such enforceability is considered in
a proceeding in equity or at law). Such counsel may rely upon opinions of other
counsel (copies of which shall be delivered to the Trustee), who shall be
counsel reasonably satisfactory to the Trustee, in which case the opinion shall
state that such counsel believes he and the Trustee are entitled so to rely.
Such counsel may also state that, insofar as such opinion involves factual
matters, he has relied, to the extent he deems proper, upon certificates of
officers of the Company and its subsidiaries and certificates of public
officials.

     The Trustee shall have the right to decline to authenticate and deliver any
Securities under this Section if the Trustee, being advised by counsel,
determines that such action may not lawfully be taken by the Company or if the
Trustee in good faith by its board of directors or board of trustees, executive
committee, or a trust committee of directors or trustees or Responsible Officers
shall determine that such action would expose the Trustee to personal liability
to existing Holders


                                       22

<PAGE>

or would affect the Trustee's own rights, duties or immunities under the
Securities, this Indenture or otherwise.

     Each Security shall be dated the date of its authentication. Unless
otherwise specified as contemplated by Section 3.01 for any Security, interest
on the each Security will accrue from the date of its authentication.

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

     Notwithstanding the foregoing and subject, in the case of a Security in
permanent global form, to Section 2.02, if any Security shall have been
authenticated and delivered hereunder but never issued and sold by the Company,
and the Company shall deliver such Security to the Trustee for cancellation as
provided in Section 3.09 together with a written statement (which need not
comply with Section 1.02 and need not be accompanied by an Opinion of Counsel)
directing such cancellation and 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 3.04. Temporary Securities

     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 and with
such appropriate insertions, omissions, substitutions and other variations as
the officers executing such Securities may determine, as evidenced by their
execution of such Securities.

     If temporary Securities of any series are issued, the Company will cause
definitive Securities of 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


                                       23

<PAGE>

Holder. Upon surrender for cancellation of any one or more temporary Securities
of any series 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 and of like tenor of authorized denominations. 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.

     SECTION 3.05. Registration, Registration of Transfer and Exchange

     The Company shall cause to be kept at the Corporate Trust Office of the
Trustee a register (the register maintained in such office and in any other
office or agency of the Company in a Place of Payment being herein sometimes
collectively referred to as the "Security Register") in which, subject to such
reasonable regulations as it may prescribe, the Company shall provide for the
registration of Securities and transfers of Securities. The Trustee is hereby
appointed "Security Registrar" for the purpose of registering Securities and
transfers of Securities as herein provided.

     Upon surrender for registration of transfer of any Security of any series
at the office or agency 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 Securities of the same
series of any authorized denominations and of a like aggregate principal amount
and of like tenor.

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

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

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


                                       24

<PAGE>

     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 3.04, 9.06 or 11.07 not involving any transfer.

     The Company shall not be required (i) to issue, register the transfer of or
exchange Securities of any series during a period beginning at the opening of
business 15 days before the day of the mailing of a notice of redemption of
Securities of that series selected for redemption under Section 11.03 and ending
at the close of business on the day of such mailing, or (ii) to register the
transfer of or exchange any Security so selected for redemption in whole or in
part, except the unredeemed portion of any Security being redeemed in part.

     The provisions of Clauses (a) - (g) below shall apply only to permanent
global Securities:

     (a) Each permanent global Security authenticated under this Indenture shall
be registered in the name of the Depositary designated for such permanent global
Security or a nominee thereof and delivered to such Depositary or a nominee
thereof or custodian therefor, and each such permanent global Security shall
constitute a single Security for all purposes of this Indenture.

     (b) Notwithstanding any other provisions in this Indenture, no permanent
global Security may be exchanged in whole or in part for Securities registered,
and no transfer of a permanent global Security in whole or in part may be
registered, in the name of any Person other than the Depositary for such
permanent global Security or a nominee thereof unless (i) the Depositary
notifies the Company pursuant to Clause 3.05(d) of this Section that it is
unwilling or unable to continue as Depositary for such permanent global Security
or if at any time the Depositary ceases to be a clearing agency registered under
the Securities Exchange Act of 1934, as amended, (ii) if the Company in its sole
discretion determines pursuant to Clause 3.05(e) of this Section that such
permanent global Security shall be so exchangeable or transferrable and executes
and delivers to the Security Registrar a Company Order providing that such
permanent global Security shall be so exchangeable or transferrable, (iii) any
event shall have occurred and be continuing which, after notice or lapse of
time, or both, would become an Event of Default with respect to the Securities
of the series of which such permanent global Security is a part or (iv) there
shall exist such circumstances, if any, in addition or in lieu of the foregoing
as have been specified for this purpose as contemplated by Section 3.01.


                                       25

<PAGE>

     (c) Subject to Clause 3.05(b) above, any exchange of a permanent global
Security for other Securities may be made in whole or in part, and all
Securities issued in exchange for a permanent global Security or any portion
thereof shall be registered in such names as the Depositary for such permanent
global Security shall direct. The Trustee shall deliver such Securities to or as
directed by the Persons in whose names such Securities are so registered.

     (d) If at any time the Depositary for any Securities of a series
represented by one or more global Securities notifies the Company that it is
unwilling or unable to continue as Depositary for such Securities or if at any
time the Depositary ceases to be a clearing agency registered under the
Securities Exchange Act of 1934, as amended, the Company shall appoint a
successor Depositary with respect to such Securities. If a successor Depositary
for such Securities is not appointed by the Company within 90 days after the
Company receives such notice or becomes aware of such ineligibility (and in any
event before the Depositary surrenders such global Security for exchange), the
Company's election that such Securities be represented by one or more global
Securities shall no longer be effective and the Company shall execute, and the
Trustee, upon receipt of an Officers' Certificate for the authentication and
delivery of definitive Securities of such series, will authenticate and deliver,
Securities of such series in definitive registered form without coupons, in any
authorized denominations, in an aggregate principal amount equal to the
principal amount of the global Security or Securities representing such
Securities in exchange for such global Security or Securities.

     (e) The Company may at any time and in its sole discretion determine that
the Securities of any series issued in the form of one or more global Securities
shall no longer be represented by a global Security or Securities. In such event
the Company will execute, and the Trustee, upon receipt of an Officers'
Certificate for the authentication and delivery of definitive Securities of such
series, will authenticate and deliver Securities of such series in definitive
registered form, in any authorized denominations, in an aggregate principal
amount equal to the principal amount of the global Security or Securities
representing such Securities, in exchange for such global Security or
Securities.

     (f) Subject to Clause 3.05(b) above, with respect to Securities represented
by a global Security, the Depositary for such global Security may surrender such
global Security in exchange in whole or in part for Securities of the same
series in definitive registered form on such terms as are acceptable to the
Company and such Depositary. Thereupon, the Company shall execute, and the
Trustee shall authenticate and deliver, without service charge,


                                       26

<PAGE>

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

          (ii) to such Depositary a new global Security in a denomination equal
     to the difference, if any, between the principal amount of the surrendered
     global Security and the aggregate principal amount of Securities
     authenticated and delivered pursuant to clause 3.05(f)(i) above.

     Upon the exchange of a global Security for Securities in definitive
registered form, in authorized denominations, such global Security shall be
canceled by the Trustee.

     (g) Every Security authenticated and delivered upon registration of
transfer of, or in exchange for or in lieu of, a permanent global Security or
any portion thereof, whether pursuant to this Section, Section 3.04, 3.06, 9.06
or 11.07 or otherwise, shall be authenticated and delivered in the form of, and
shall be, a permanent global Security, unless such Security is registered in the
name of a Person other than the Depositary for such permanent global Security or
a nominee thereof.

     SECTION 3.06. Mutilated, Destroyed, Lost and Stolen Securities

     If any mutilated Security is surrendered to the Trustee, the Company shall
execute and the Trustee shall authenticate and deliver in exchange therefor a
new Security of the same series and of like tenor and principal amount and
bearing a number not contemporaneously outstanding.

     If there shall be delivered to the Company and the Trustee (i) evidence to
their satisfaction of the destruction, loss or theft of any Security 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 has been acquired by a bona fide
purchaser, the Company shall execute and the Trustee shall authenticate and
deliver, in lieu of any such destroyed, lost or stolen Security, a new Security
of the same series and of like tenor and principal amount and bearing a number
not contemporaneously outstanding.

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


                                       27

<PAGE>

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

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

     SECTION 3.07. Payment of Interest; Interest Rights Preserved

     Unless otherwise provided as contemplated by Section 3.01 with respect to
any Security, interest on such Security which is payable, and is punctually paid
or duly provided for, on any Interest Payment Date shall be paid to the Person
in whose name that Security (or one or more Predecessor Securities) is
registered at the close of business on the Regular Record Date for such
interest; provided that if that Security or its Predecessor Security was
originally issued on a date after a Regular Record Date and before the following
Interest Payment Date, the first payment of interest on such Security will be
made on the Interest Payment Date following the next succeeding Regular Record
Date. Unless otherwise specified as contemplated by Section 3.01 for any
Security, interest payable at Maturity (other than on a date which is an
Interest Payment Date) will be paid to the same Person to whom the principal
amount of this Security is payable.

     Any interest on any Security of any series which is payable, but is not
punctually paid or duly provided for, on any Interest Payment Date (herein
called "Defaulted Interest") shall forthwith cease to be payable to the Holder
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 (a) or (b) below:

     (a) The Company may elect to make payment of any Defaulted Interest to the
Persons in whose names the 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


                                       28

<PAGE>
 of Defaulted Interest proposed to be paid on each Security of such series and
the date of the proposed payment, and at the same time the Company shall deposit
with the Trustee an amount of money equal to the aggregate amount proposed to be
paid in respect of such Defaulted Interest or shall make arrangements
satisfactory to the Trustee for such deposit prior to the date of the proposed
payment, such money when deposited to be held in trust for the benefit of the
Persons entitled to such Defaulted Interest as in this Clause provided.
Thereupon the Trustee shall fix a Special Record Date for the payment of such
Defaulted Interest which shall be not more than 15 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 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. Notice of the proposed payment of such Defaulted
Interest and the Special Record Date therefor having been so mailed, such
Defaulted Interest shall be paid to the Persons in whose names the 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 3.07(b).

     (b) The Company may make payment of any Defaulted Interest on the
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, each Security
delivered under this Indenture upon registration of transfer of or in exchange
for or in lieu of any other Security shall carry the rights to interest accrued
and unpaid, and to accrue, which were carried by such other Security.

     SECTION 3.08. Persons Deemed Owners

     Prior to due presentment of a Security for registration of transfer, the
Company, the Trustee and any agent of the Company or the Trustee may treat the
Person in whose name such Security is registered as the owner of such Security
for the purpose of receiving payment of principal of (and premium, if any) and
(subject to Section 3.07) interest on such Security and for all other purposes
whatsoever, whether or not such Security is overdue, and neither the Company,


                                       29

<PAGE>

the Trustee nor any agent of the Company or the Trustee shall be affected by
notice to the contrary.

     SECTION 3.09. Cancellation

     All Securities surrendered for payment, redemption, 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 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. 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. All canceled Securities held by the
Trustee shall be disposed of in accordance with the Trustee's customary
procedures.

     SECTION 3.10. Computation of Interest

     Except as otherwise specified as contemplated by Section 3.01 for any
Security, interest on the Securities of each series shall be computed on the
basis of a 360-day year consisting of 12 30-day months.

     SECTION 3.11. CUSIP Numbers

     The Company in issuing the Securities may use "CUSIP" numbers (if then
generally in use), and, if so, the Trustee shall use "CUSIP" numbers in notices
of redemption as a convenience to Holders; provided that any such notice may
state that no representation is made as to the correctness of such numbers
either as printed on the Securities or as contained in any notice of a
redemption and that reliance may be placed only on the other identification
numbers printed on the Securities, and any such redemption shall not be affected
by any defect in or omission of such numbers. The Company will promptly notify
the Trustee of any change in the "CUSIP" numbers.

                           SATISFACTION AND DISCHARGE

     SECTION 4.01. Satisfaction and Discharge of Indenture

     This Indenture shall upon Company Request cease to be of further effect
(except as to any surviving rights of registration of transfer or exchange of
Securities herein expressly provided for), and the Trustee, at the expense of
the Company, shall execute proper instruments acknowledging satisfaction and
discharge of this Indenture, when

     (a) either

          (i) all Securities theretofore authenticated and delivered (other than
     (x) Securities which have been destroyed, lost or stolen and which have
     been replaced or paid as provided in Section 3.06 and (y) Securities 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 10.03) have been
     delivered to the Trustee for cancellation; or

          (ii) all such Securities not theretofore delivered to the Trustee for
     cancellation

               (A) have become due and payable, or

               (B) will become due and payable at their Stated Maturity within
          one year, or

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


                                       31

<PAGE>

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

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

     Notwithstanding the satisfaction and discharge of this Indenture, the
obligations of the Company to the Trustee under Sections 4.03(b) and 6.07, the
obligations of the Company to any Authenticating Agent under Section 6.14 and,
if money shall have been deposited with the Trustee pursuant to subclause
4.01(a)(ii), the obligations of the Trustee under Section 4.03 and the last
paragraph of Section 10.03 shall survive.

     SECTION 4.02. Defeasance of Securities of Any Series

     Unless otherwise specified pursuant to Section 3.01 with respect to any
Security, then notwithstanding Section 4.01, the Company shall be deemed to have
paid and discharged the entire indebtedness on all the Outstanding Securities of
any series on the 91st day after the date of the deposit referred to in
subparagraph 4.02(d) hereof, and the provisions of this Indenture, as it relates
to such Outstanding Securities, shall no longer be in effect (and the Trustee,
at the expense of the Company, shall at Company Request, execute proper
instruments acknowledging the same) (hereinafter called "Defeasance"), except as
to:

     (a) the rights of Holders of Securities to receive, from the trust funds
described in subparagraph 4.02(d) hereof, (i) payment of the principal of and
any premium or interest on the Outstanding Securities of that series on the
Stated Maturity of such principal or installment of principal or interest and
(ii) the benefit of any mandatory sinking fund payments or analogous payments
applicable to Securities of such series on the day on which such payments are
due and payable in accordance with the terms of the Indenture and such
Securities;

     (b) the Company's obligations with respect to such Securities under
Sections 3.05, 3.06, 4.03, 10.02 and 10.03; and

     (c) the rights, powers, trusts, duties and immunities of the Trustee
hereunder;

     provided that the following conditions have been satisfied:


                                       32

<PAGE>

     (d) with reference to this provision, the Company has irrevocably deposited
or caused to be irrevocably deposited with the Trustee as trust funds for the
purpose of making the following payments, specifically pledged as security for,
and dedicated solely to, the benefit of the Holders of the Securities of that
series, (i) money in an amount, or (ii) U.S. Government Obligations which
through the payment of interest and principal in respect thereof in accordance
with their terms will provide not later than one day before the due date of any
payment referred to in clause (A) or (B) of this subparagraph 4.02(d) money in
an amount, or (iii) a combination thereof, sufficient, in the opinion of a
nationally recognized firm of independent public accountants expressed in a
written certification thereof delivered to the Trustee, to pay and discharge,
and which shall be applied by the Trustee for such purposes, (A) the principal
of and any premium or interest on the Outstanding Securities of that series on
the Stated Maturity of such principal or installment of principal or interest on
the Redemption Date, as the case may be, and (B) any mandatory sinking fund
payments or analogous payments applicable to Securities of such series on the
day on which such payments are due and payable, each in accordance with the
terms of this Indenture and of such Securities;

     (e) such Defeasance shall not cause the Trustee with respect to the
Securities of that series to have a conflicting interest as defined in Section
6.08 and for purposes of the Trust Indenture Act with respect to the Securities
of any series;

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

     (g) such Defeasance would not cause any Outstanding Security of such series
then listed on any nationally recognized securities exchange to be then delisted
as a result thereof;

     (h) no Event of Default or event which with notice or lapse of time would
become an Event of Default with respect to Securities of the series shall have
occurred and be continuing on the date of such deposit or during the period
ending on the 91st day after such date;

     (i) the Company has delivered to the Trustee an Opinion of Counsel based on
the fact that (x) the Company has received from, or there has been published by,
the Internal Revenue Service a ruling or (y) since the date hereof, there has
been a change in the applicable Federal income tax law, in either case to the
effect that, and such opinion shall confirm that, the Holders of the Securities
of such series will not recognize income, gain or loss for Federal income tax


                                       33

<PAGE>

purposes as a result of such deposit, defeasance and discharge and will be
subject to Federal income tax on the same amount and in the same manner and at
the same times, as would have been the case if such deposit, defeasance and
discharge had not occurred;

     (j) the Company has delivered to the Trustee an Opinion of Counsel stating
that (i) such deposit, defeasance and discharge would not cause any outstanding
Security of such series then listed on any nationally recognized securities
exchange to be delisted as a result thereof; and (ii) and that such Defeasance
would not result in the trust arising from such deposit constituting an
investment company within the meaning of the Investment Company Act of 1940, as
amended from time to time;

     (k) the Company has delivered to the Trustee an Opinion of Counsel to the
effect that after the 91st day following the deposit, the trust funds will not
be subject to the effect of any applicable bankruptcy, insolvency,
reorganization or similar laws affecting creditors' rights generally, except
that if a court were to rule under any such law in any case or proceeding that
the trust funds remained property of the Company, no opinion is given as to the
effect of such laws on the trust funds except the following: (A) assuming such
trust funds remained in the Trustee's possession prior to such court ruling to
the extent not paid to Holders of Securities, the Trustee will hold, for the
benefit of such Holders, a valid and perfected security interest in such trust
funds that is not avoidable in bankruptcy or otherwise, and (B) such Holders
will be entitled to receive adequate protection of their interests in such trust
funds if such trust funds are used; and

     (l) the Company has delivered to the Trustee an Officers' Certificate and
an Opinion of Counsel, each stating that all conditions precedent provided for
relating to the Defeasance contemplated by this provision have been complied
with.

     SECTION 4.03. Application of Trust Funds; Indemnification

     (a) Subject to the provisions of the last paragraph of Section 10.03, all
money deposited with the Trustee pursuant to Section 4.01, all money and U.S.
Government Obligations deposited with the Trustee pursuant to Section 4.02 and
all money received by the Trustee in respect of U.S. Government Obligations
deposited with the Trustee pursuant to Section 4.02 shall be held in trust and
applied by it, in accordance with the provisions of the Securities and this
Indenture, to the payment, either directly or through any Paying Agent
(including the Company acting as its own Paying Agent) as the Trustee may
determine, to the Persons entitled thereto of the principal (and premium, if
any) and interest for whose payment such money has been deposited with or
received by the Trustee or


                                       34

<PAGE>

to make mandatory sinking fund payments or analogous payments as contemplated by
Section 4.02.

     (b) The Company shall pay and shall indemnify the Trustee against any tax,
fee or other charge imposed on or assessed against U.S. Government Obligations
deposited pursuant to Section 4.02 or the interest and principal received in
respect of such obligations other than any payable by or on behalf of Holders.

     (c) The Trustee shall deliver or pay to the Company from time to time upon
Company Request any money or U.S. Government Obligations held by it as provided
in Section 4.02 which, in the opinion of a nationally recognized firm of
independent public accountants expressed in a written certification thereof
delivered to the Trustee, are then in excess of the amount which then would have
been required to be deposited for the purpose for which such money or U.S.
Government Obligations were deposited or received.

     SECTION 4.04. Reinstatement

     If the Trustee or the Paying Agent is unable to apply any money in
accordance with Section 4.02 with respect to any Securities by reason of any
order or judgment of any court or governmental authority enjoining, restraining
or otherwise prohibiting such application or upon the occurrence of an Event of
Default, then the obligations under this Indenture and such Securities from
which the Company has been discharged or released pursuant to Section 4.02 shall
be revived and reinstated as though no deposit had occurred pursuant to this
Article with respect to such Securities, until such time as the Trustee or
Paying Agent is permitted to apply all money held in trust pursuant to Section
4.03 with respect to such Securities in accordance with this Article; provided,
however, that if the Company makes any payment of principal of or any premium or
interest on any such Security following such reinstatement of its obligations,
the Company shall be subrogated to the rights (if any) of the Holders of such
Securities to receive such payment from the money so held in trust.

                                    ARTICLE 5

whose performance or whose breach is elsewhere in this Section specifically
dealt with or which has expressly been included in this Indenture solely for the
benefit of a series of Securities other than that series), and continuance of
such default or breach for a period of 90 days after there has been given, by
registered or certified mail, to the Company by the Trustee or to the Company
and the Trustee by the Holders of at least 25% in principal amount of the
Outstanding Securities of each series affected thereby a written notice
specifying such default or breach and requiring it to be remedied and stating

ordering the winding up or liquidation of its affairs, and the continuance of
any such decree or order for relief or any such other decree or order unstayed
and in effect for a period of 60 consecutive days; or

     (f) the commencement by the Company of a voluntary case or proceeding under
any applicable Federal or State bankruptcy, insolvency, reorganization or other
similar law or of any other case or proceeding to be adjudicated a bankrupt or

or the making by it of any assignment for the benefit of creditors, or the
admission by it in writing of its inability to pay its debts generally as they
become due, or the taking of corporate action by the Company in furtherance of
any such action; or

     (g) any events of default provided with respect to Securities of that
series.

     SECTION 5.02. Acceleration of Maturity; Rescission and Annulment

     If an Event of Default described in clause 5.01(a), 5.01(b), 5.01(c),
5.01(d) or 5.01(g) with respect to Securities of any series at the time
Outstanding occurs and is continuing, then in every such case the Trustee or the
Holders of not less than 25% in principal amount of the Outstanding Securities
of such series (each such series voting as a separate class in the case of an
Event of Default under clause 5.01(a), 5.01(b), 5.01(c) or 5.01(g), and all such
series voting as one class in the case of such an Event of Default under clause
5.01(d)) may declare the principal amount (or, if any Securities are Original
Issue Discount Securities, such portion of the principal amount as may be
specified in the terms of such Securities) of all of the Securities of such
series to be due and payable immediately, by a notice in writing to the Company
(and to the Trustee if given by Holders), and upon any such declaration such
principal amount (or specified amount) shall become immediately due and payable.
If any Event of Default described in clause 5.01(d) with respect to all series
of Securities then Outstanding, or any Event of Default described in clause
5.01(e) or 5.01(f) occurs and is continuing, then in every such case the Trustee
or the Holders of not less than 25% in aggregate principal amount of all the
Outstanding Securities (voting as one class) may declare the principal amount
(or, if any Securities are Original Issue Discount Securities, such portion of
the principal amount as may be specified in the terms of such Securities) of all
the Securities then Outstanding to be due and payable immediately, by a notice
in writing to the Company (and to the Trustee if given by Holders), and upon any
such declaration such principal amount (or specified amount) 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


                                       37

<PAGE>

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

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

          (i) the overdue interest on all Securities of the series,

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

          (iii) to the extent that payment of such interest is lawful, interest
     upon overdue interest at the rate or rates prescribed for overdue interest
     in such Securities, and

          (iv) all sums paid or advanced by the Trustee hereunder and the
     reasonable compensation, expenses, disbursements and advances of the
     Trustees, its agents and counsel and all other amounts due under Section
     6.07;

          and

     (b) all Events of Default with respect to Securities of that series other
than the non-payment of the principal of Securities of that series which have
become due solely by such declaration of acceleration, have been cured or waived
as provided in Section 5.13.

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

     SECTION 5.03. Collection of Indebtedness and Suits for Enforcement by
Trustee

     The Company covenants that if

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


                                       38

<PAGE>
     (b) default is made in the payment of the principal of (or premium, if any,
on) any Security at the Maturity thereof the Company will, upon demand of the
Trustee, pay to it, for the benefit of the Holders of such Securities, the whole
amount then due and payable on such Securities, for principal (and premium, if
any) and interest and, to the extent that payment of such interest shall be
legally enforceable, interest on any overdue principal (and premium, if any) and
on any overdue interest, at the rate or rates prescribed therefor in such
Securities and, in addition thereto, such further amount as shall be sufficient
to cover the costs and expenses of collection, including the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel other than those incurred due to the Trustee's bad faith or
negligence.

     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, may
prosecute such proceeding to judgment or final decree and may enforce the same
against the Company or any other obligor upon such Securities 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, 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 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 therein, or to enforce any other proper remedy.

     SECTION 5.04. Trustee May File Proofs of Claim

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


                                       39

<PAGE>

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

     (b) 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 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 it for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, and any other
amounts due the Trustee under Section 6.07.

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

     SECTION 5.05. Trustee May Enforce Claims Without Possession of Securities

     All rights of action and claims under this Indenture or the Securities may
be prosecuted and enforced by the Trustee without the possession of any of the
Securities 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 in respect of which such judgment has been
recovered.

     SECTION 5.06. 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 and the notation
thereon of the payment if only partially paid and upon surrender thereof if
fully paid:


                                       40

<PAGE>

               FIRST: To the payment of all amounts due the Trustee under this
          Indenture; and

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

     SECTION 5.07. Limitation on Suits

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

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

     (b) 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;

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

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

     (e) no direction inconsistent with such written request has been given to
the Trustee during such 60-day period by the Holders of a majority in principal
amount of all 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 of such Holders.

     SECTION 5.08. Unconditional Right of Holders to Receive Principal, Premium
and Interest

     Notwithstanding any other provision in this Indenture, the Holder of any
Security shall have the right, which is absolute and unconditional, to receive
payment of the principal of (and premium, if any) and (subject to Section 3.07)
interest on such Security on the Stated Maturity or Maturities expressed in such
Security (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 5.09. Restoration of Rights and Remedies

     If the Trustee or any Holder 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, subject to any determination in
such proceeding, the Company, the Trustee and the Holders shall 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 5.10. Rights and Remedies Cumulative

     Except as otherwise provided with respect to the replacement or payment of
mutilated, destroyed, lost or stolen Securities in the last paragraph of Section

the Holders 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 5.11. Delay or Omission Not Waiver

     No delay or omission of the Trustee or of any Holder of any Securities to
exercise any right or remedy accruing upon any Event of Default which shall have
occurred and shall be continuing 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, as the case may be.

     SECTION 5.12. Control by Holders

     The Holders of a majority in principal amount of the Outstanding Securities
of any series shall have the right to direct the time, method and place of
conducting any proceeding for any remedy available to the Trustee, or exercising
any trust or power conferred on the Trustee, with respect to the Securities of
such series, provided that

     (a) such direction shall not be in conflict with any rule of law or with
this Indenture,

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

     (c) the Trustee shall have the right to decline any direction with respect
to which a Responsible Officer reasonably determines such direction will cause
the Trustee to incur any liability for which it shall not have been adequately
indemnified pursuant to Section 5.07.

     SECTION 5.13. Waiver of Past Defaults

     The Holders of (i) not less than a majority in principal amount of the
Outstanding Securities of any series (each such series voting as a separate
class) may on behalf of the Holders of all Securities of such series waive any
past default or Event of Default described in clause 5.01(d) which relates to
less than all series of Outstanding Securities or described in clause 5.01(g)
with respect to such series and its consequences, or (ii) not less than a
majority in principal amount of the Outstanding Securities affected thereby
(voting as one class) may on behalf of the Holders of all the Outstanding
Securities affected thereby waive any past default or Event of Default described
in said clause 5.01(d) which relates to all such Outstanding Securities and its
consequences, except in any such case a default

     (a) in the payment of the principal of, or any premium or interest on, any
Security of such series, or

     (b) 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


                                       43

<PAGE>

of this Indenture; but no such waiver shall extend to any subsequent or other
default or impair any right consequent thereon.

     SECTION 5.14. 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,
suffered or omitted by it as Trustee, the filing by any party litigant in such
suit of an undertaking to pay the costs of such suit, and that such court may in
its discretion assess reasonable costs, including reasonable attorneys' fees and
expenses, 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
Company, to any suit instituted by the Trustee, to any suit instituted by any
Holder, or group of Holders, holding in the aggregate more than 25% in principal
amount of the Outstanding Securities of any series or to any suit instituted by
any Holder for the enforcement of the payment of the principal of (or premium,
if any) or interest on any Security on or after the Stated Maturity or
Maturities expressed in such Security (or, in the case of redemption, on or
after the Redemption Date).

     SECTION 5.15. Waiver of Usury, Stay or Extension Law

     The Company covenants (to the extent that it may lawfully do so) that it
will not at any time insist upon, or plead, or in any manner whatsoever claim or
take the benefit or advantage of, any stay or extension of 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 6.01. Certain Duties and Responsibilities

<PAGE>

          (i) the Trustee undertakes to perform such duties and only such duties
     as specifically set forth in this Indenture, and no implied covenants or
     obligations shall be read into this Indenture against the Trustee; and

          (ii) in the absence of bad faith on its part, the Trustee may
     conclusively rely, as to the truth of the statements and the correctness of
     the opinions expressed therein, upon certificates or opinions furnished to
     the Trustee and conforming to the requirements of this Indenture; but in
     the case of any such certificates or opinions which by any provision hereof
     are specifically required to be furnished to the Trustee, the Trustee shall
     be under a duty to examine the same to determine whether or not they
     conform to the requirements of this Indenture.

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

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

          (i) this Subsection shall not be construed to limit the effect of
     Subsection 6.01(a);

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

          (iii) the Trustee shall not be liable with respect to any action taken
     or omitted to be taken by it in good faith in accordance with the direction
     of the Holders of a majority in principal amount of the Outstanding
     Securities of any series, determined as provided in Section 5.12, relating
     to the time, method and place of conducting any proceeding for any remedy
     available to the Trustee, or exercising any trust or power conferred upon
     the Trustee, under this Indenture with respect to the Securities of such
     series; and

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


                                       45

<PAGE>

     repayment of such funds or indemnity satisfactory to it against such risk
     or liability is not reasonably assured to it.

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

     SECTION 6.02. Notice of Defaults

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 Section

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 Securities of such series, the Trustee shall be
protected in withholding such notice if and so long as the board of directors,
the executive committee or a trust committee of directors or Responsible
Officers of the Trustee in good faith determine that the withholding of such
notice is in the interest of the Holders of Securities of such series; and
provided, further, that in the case of any default of the character specified in
Section 5.01(d) with respect to Securities of such series, no such notice to
Holders shall be given until at least 30 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 Securities of such series.

     SECTION 6.03. Certain Rights of Trustee

     Subject to the provisions of Section 6.01:

an Officers' Certificate;

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

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

agents and employees. Such immunities and protections and right to
indemnification,


                                       47

<PAGE>

together with the Trustee's right to compensation, shall survive the Trustee's
resignation or removal and final payment of the Securities;

     (j) the Trustee shall not be deemed to have notice of any Default or Event
of Default unless a Responsible Officer of the Trustee has actual knowledge
thereof or unless written notice of any event which is in fact such a default is
received by the Trustee at the Corporate Trust Office of the Trustee, and such
notice references the Securities and this Indenture; and

     (k) the Trustee may request that the Company deliver an Officers'
Certificate setting forth the names of individuals and/or titles of officers
authorized at such time to take specified actions pursuant to this Indenture,
which Officers' Certificate may be signed by any person authorized to sign an
Officers' Certificate, including any person specified as so authorized in any

Indenture for payment or reimbursement to the Trustee of its fees, expenses and
any other monies payable to it hereunder.

     SECTION 6.08. Disqualification; Conflicting Interest

     (a) If the Trustee has or shall acquire any conflicting interest within the
meaning of the Trust Indenture Act with respect to the Securities of any series,

of at least $50,000,000 subject to supervision or examination by Federal or
State authority and having its Corporate Trust Office in any State in the United
States of America or in the District of Columbia. If such corporation publishes
or files reports of condition at least annually, pursuant to law or to the
requirements of said supervising or examining authority, then for the purposes
of this Section the combined capital and surplus of such corporation shall be
deemed to be its combined capital and surplus as set forth in its most recent
report of condition so published or filed. 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 6.10. Resignation and Removal; Appointment of Successor

     (a) No resignation or removal of the Trustee and no appointment of a

acceptance of appointment by the successor Trustee in accordance with the
applicable requirements of Section 6.11.

     (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 the
instrument of acceptance by a successor Trustee required by Section 6.11 shall

notice of resignation, the resigning Trustee may petition any court of competent
jurisdiction at the expense of the Company for the appointment of a successor
Trustee with respect to the Securities of such series.

     (c) The Trustee may be removed at any time with respect to the Securities

                                       50

<PAGE>

     (d) If at any time:

          (i) the Trustee shall fail to comply with Section 6.08(a) after
     written request therefor by the Company or by any Holder who has been a
     bona fide Holder of a Security for at least six months, or

          (ii) the Trustee shall cease to be eligible under Section 6.09 and
     shall fail to resign after written request therefor by the Company or by
     any such Holder, or

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

     (e) 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
removal, the Trustee being removed may petition, at the expense of the Company,
any court of competent jurisdiction for the appointment of a successor Trustee
with respect to the Securities of such series.

     (f) 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 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) and shall comply with the applicable
requirements of Section 6.11. 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,


                                       51

<PAGE>

forthwith upon its acceptance of such appointment in accordance with the
applicable requirements of Section 6.11, 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 and accepted appointment in the manner required by Section 6.11, any
Holder who has been a bona fide holder of a Security of such series for at least
six months may, on behalf of himself and all others similarly situated, petition
any court of competent jurisdiction for the appointment of a successor Trustee
with respect to the Securities of such series.

     (g) 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 by mailing
written notice of such event by first-class mail, postage prepaid, to all
Holders of Securities of such series as their names and addresses appear in the
Security Register. 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 6.11. 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 so appointed shall
execute, acknowledge and deliver to the Company and to 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 the 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.

     (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
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


                                       52

<PAGE>

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 6.11(a) or 6.11(b), as the case may be.

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

     SECTION 6.12. Merger, Conversion, Consolidation or Succession to Business

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

deliver the Securities so authenticated with the same effect as if such
successor Trustee had itself authenticated such Securities.

     SECTION 6.13. Preferential Collection of Claims

     If and when the Trustee shall be or become a creditor of the Company (or
any other obligor upon the Debt Securities), the Trustee shall be subject to the
provisions of the Trust Indenture Act regarding the collection of claims against
the Company (or any such other obligor).

     SECTION 6.14. Appointment of Authenticating Agent

     At any time 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
original issue, exchange, registration of transfer or partial redemption thereof
or pursuant to Section 3.06, and Securities so authenticated shall be entitled
to the benefits of this Indenture and shall be valid and obligatory for all
purposes as if authenticated by the Trustee hereunder. Wherever reference is
made in this Indenture to the authentication and delivery of Securities by the
Trustee or the Trustee's certificate of authentication, such reference shall be
deemed to include authentication and delivery on behalf of the Trustee by an
Authenticating Agent and a certificate of authentication executed on behalf of
the Trustee by an Authenticating Agent. Each Authenticating Agent shall be
acceptable to the Company and shall at all times be a corporation organized and
doing business under the laws of the United States of America, any State thereof
or the District of Columbia, authorized under such laws to act as 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 authority. If such
Authenticating Agent publishes reports of condition at least annually, pursuant
to law or to the requirements of said supervising or examining authority, then
for the purposes of this Section, the combined capital and surplus of such
Authenticating Agent shall be deemed to be its combined capital and surplus as
set forth in its most recent report of condition so published. If at any time an
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, such Authenticating Agent shall resign immediately
in the manner and with the effect specified in this Section.

     Any corporation into which an Authenticating Agent may be merged or
converted or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which such Authenticating Agent
shall be a party, or any corporation succeeding to all or substantially all the
corporate agency or corporate trust business of an Authenticating Agent, shall
continue to be an Authenticating Agent, provided such corporation shall be
otherwise eligible

under this Section, without the execution or filing of any paper or any further
act on the part of the Trustee or such Authenticating Agent.

     An Authenticating Agent may resign at any time by giving written notice
thereof to the Trustee and to the Company. The Trustee may at any time terminate
the agency of an Authenticating Agent by giving written notice thereof to such
Authenticating Agent and to the Company. Upon receiving such a notice of
resignation or upon such a termination, or in case at any time such
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, the Trustee may appoint a successor Authenticating
Agent which shall be acceptable to the Company and shall mail written notice of
such appointment by first-class mail, postage prepaid, to all Holders of
Securities of the series with respect to which such Authenticating Agent will
serve, as their names and addresses appear in the Security Register. Any
successor Authenticating Agent upon acceptance of its appointment hereunder
shall become vested with all the rights, powers and duties of its predecessor
hereunder, with like effect as if originally named as an Authenticating Agent.
No successor Authenticating Agent shall be appointed unless eligible under the
provisions of this Section.

     The Company agrees to pay to each Authenticating Agent from time to time
reasonable compensation 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 the Trustee's certificate of authentication, an alternate
certificate of authentication in the following form:

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

                HOLDERS' LIST AND REPORTS BY TRUSTEE AND COMPANY

     SECTION 7.01. Company to Furnish Trustee Names and Addresses of Holders

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

     (a) semi-annually a list, in such form as the Trustee may reasonably
require, of the names and addresses of the Holders as of the date of such list,
and

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

     SECTION 7.02. Preservation of Information; Communications to Holders

     (a) The Trustee shall preserve, in as current a form as is reasonably
practicable, the names and addresses of Holders contained in the most recent
list furnished to the Trustee as provided in Section 7.01 and the names and
addresses of Holders received by the Trustee in its capacity as Security
Registrar. The Trustee may destroy any list furnished to it as provided in
Section 7.01 upon receipt of a new list so furnished.

     (b) If three or more Holders of Securities of any series (herein referred
to as "applicants") apply in writing to the Trustee, and furnish to the Trustee
reasonable proof that each such applicant has owned a Security of such series
for a period of at least six months preceding the date of such application, and
such application states that the applicants desire to communicate with other
Holders of such series or with Holders of all other series of Securities with
respect to their rights under this Indenture or under such Securities and is
accompanied by a copy of the form of proxy or other communication which such
applicants propose to transmit, then the Trustee shall, within five business
days after the receipt of such application, at its election, either

          (i) afford such applicants access to the information preserved at the
     time by the Trustee in accordance with Section 7.02(a), or

          (ii) inform such applicants as to the approximate number of Holders of
     such series of Securities or Holders of all other series of Securities
     whose names and addresses appear in the information preserved


                                       56

<PAGE>

     at the time by the Trustee in accordance with Section 7.02(a), and as to
     the approximate cost of mailing to the Holders of such series of Securities
     or the Holders of all series of Securities the form of proxy or other
     communication, if any, specified in such application.

     If the Trustee shall elect not to afford such applicants access to such
information, the Trustee shall, upon the written request of such applicants,
mail to each Holder of such series of Securities or of all series of Securities
or of all series of Securities whose name and address appear in the information
preserved at the time by the Trustee in accordance with Section 7.02(a) a copy
of the form of proxy or other communication which is specified in such request,
with reasonable promptness after a tender to the Trustee of the material to be
mailed and of payment, or provision for the payment, of the reasonable expenses
of mailing, unless within five days after such tender the Trustee shall mail to
such applicants and file with the Commission, together with a copy of the
material to be mailed, a written statement to the effect that, in the opinion of
the Trustee, such mailing would be contrary to the best interest of the relevant
Holders or would be in violation of applicable law. Such written statement shall
specify the basis of such opinion. If the Commission, after opportunity for a
hearing upon the objections specified in the written statement so filed, shall
enter an order refusing to sustain any of such objections or if, after the entry
of an order sustaining one or more of such objections, the Commission shall
find, after notice and opportunity for hearing, that all the objections so
sustained have been met and shall enter an order so declaring, the Trustee shall
mail copies of such material to all such Holders with reasonable promptness
after the entry of such order and the renewal of such tender; otherwise the
Trustee shall be relieved of any obligation or duty to such applicants
respecting their application.

     (c) Every Holder of Securities, by receiving and holding the same, agrees
with the Company and the Trustee that neither the Company nor the Trustee nor
any agent of either of them shall be held accountable by reason of the
disclosure of any such information as to the names and addresses of the Holders
in accordance with Section 7.02(b), regardless of the source from which such
information was derived, and that the Trustee shall not be held accountable by
reason of mailing any material pursuant to a request made under Section 7.02(b).

     SECTION 7.03. Reports by Trustee

     (a) If required under Section 313(a) of the Trust Indenture Act, within 60
days after May 15 of each year commencing with the year 2001, so long as any of
the Securities are outstanding, the Trustee shall transmit by mail to all
Holders, as provided in subsection 7.03(c), a brief report dated as of such May
15 with respect to any of the following events which may have occurred within
the


                                       57

<PAGE>

previous 12 months (but if no such event has occurred within such period no
report need by transmitted):

          (i) any change to its eligibility under Section 6.09 or the creation
     of or any material change to its qualifications under Section 6.08;

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

          (iii) any change to the amount, interest rate and maturity date of all
     other indebtedness owing by the Company (or by any other obligor on the
     Securities) to the Trustee in its individual capacity, on the date of such
     report, with a brief description of any property held as collateral
     security therefor, except an indebtedness based upon a creditor
     relationship arising in any manner described in Section 6.13;

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

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

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

     (b) The Trustee shall transmit by mail to all Holders, as provided in
subsection 7.03(c), a brief report with respect to the character and amount of
any advances (and if the Trustee elects so to state, the circumstances
surrounding the making thereof) made by the Trustee (as such) since the date of
the last report transmitted pursuant to Subsection 7.03(a) (or if no such report
has yet been so transmitted, since the date of execution of this instrument) for
the reimbursement of which it claims or may claim a lien or charge, prior to
that of the Securities, on property or funds held or collected by it as Trustee
and which it has not previously


                                       58

<PAGE>

reported pursuant to this Subsection, except that the Trustee shall not be
required (but may elect) to report such advances if such advances remaining
unpaid at any time aggregate 10% or less of the principal amount of the
Securities Outstanding of such series at such time, such report to be
transmitted within 90 days after such time.

     (c) Reports pursuant to this Section shall be transmitted by mail:

          (i) to all Holders of Securities, as the names and addresses of such
     Holders appear in the Security Register as of a date not more than fifteen
     days prior to the mailing thereof;

          (ii) to such holders of Securities of any series as have, within two
     years preceding such transmission, filed their names and addresses with the
     Trustee for such series for that purpose; and

          (iii) except in the case of reports pursuant to subsection 7.03(b), to
     all Holders of Securities whose names and addresses have been received by
     the Trustee pursuant to Section 7.01.

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

     SECTION 7.04. Reports by Company

     The Company shall:

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


                                       59

<PAGE>

national securities exchange as may be prescribed from time to time in such
rules and regulations;

     (b) file with the Trustee and the Commission, in accordance with rules and
regulations prescribed from time to time by the Commission, such additional
information, documents and reports with respect to compliance by the Company
with the conditions and covenants of this Indenture as may be required from time
to time by such rules and regulations; and

     (c) transmit by mail to all Holders, as their names and addresses appear in
the Security Register, within 30 days after the filing thereof with the Trustee,
to such Holders of Securities as have, within the two years preceding such
transmission, filed their names and addresses with the Trustee for that purpose
and Holders of securities whose names and addresses have been furnished to or
received by the Trustee pursuant to Section 7.02(a) such summaries of any
information, documents and reports required to be filed by the Company pursuant
to paragraphs 7.04(a) and 7.04(b) as may be required by rules and regulations
prescribed from time to time by the Commission.

     Delivery of such reports, information and documents to the Trustee is for
informational purposes only and the Trustee's receipt of such shall not
constitute constructive notice of any information contained therein or
determinable from information contained therein, including the Company's
compliance with any of its covenants hereunder (as to which the Trustee is
entitled to rely exclusively on Officers' Certificates).

     SECTION 7.05. Calculation of Original Issue Discount

     The Company shall file with the Trustee promptly after the end of each
calendar year (i) a written notice specifying the amount of original issue

              CONSOLIDATION, MERGER, CONVEYANCE, TRANSFER OR LEASE

     SECTION 8.01. Company May Consolidate, Etc., Only on Certain Terms

     Nothing contained in this Indenture or in any of the Securities shall
prevent any consolidation or merger of the Company with or into any other
corporation or corporations, or successive consolidations or mergers in which
the Company or its successor or successors shall be a party or parties or shall
prevent any sale or conveyance of all or substantially all of the property of
the Company to any other corporation authorized to acquire and operate the same;
provided, that in any such case, (i) either the Company shall be the continuing
corporation, or the successor corporation (if other than the Company) shall be a
corporation organized and existing under the laws of the United States of
America or a State thereof and such corporation shall expressly assume the due
and punctual payment of the principal of, and premium, if any, and interest on
all the Securities, according to their tenor, and the due and punctual
performance and observance of all of the covenants and conditions of this
Indenture to be performed by the Company by supplemental indenture satisfactory
to the Trustee, executed and delivered to the Trustee by such corporation, and
(ii) the Company or such successor corporation, as the case may be, shall not,
immediately after such merger or consolidation, or such sale or conveyance, be
in default in the performance of any such covenant or condition.

     SECTION 8.02. Successor Corporation to be Substituted for Company

     In case of any such consolidation, merger, sale or conveyance (other than a
conveyance by way of lease) and upon any such assumption by the successor
corporation, such successor corporation shall succeed to and be substituted for
the Company, with the same effect as if it had been named herein as the party of
the first part, and the Company thereupon shall be relieved of any further
liability or obligation hereunder or upon the Securities and may thereupon or at
any time thereafter be dissolved, wound up or liquidated. Such successor
corporation thereupon may cause to be signed, and may issue either in its own
name or in the name of Masco Corporation, any or all of the Securities issuable
hereunder which theretofore shall not have been signed by the Company and
delivered to the Trustee or the Authenticating Agent; and upon the order of such
successor corporation (instead of the Company) and subject to all the terms,
conditions and limitations in this Indenture prescribed, the Trustee or the
Authenticating Agent shall authenticate and deliver any Securities which
previously shall have been signed and delivered by the officers of the Company
to the Trustee or the Authenticating Agent for authentication, and any
Securities which such successor corporation thereafter shall cause to be signed
and delivered to the Trustee or the


                                       61

<PAGE>

Authenticating Agent 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.

     In the case of any such consolidation, merger, sale or conveyance, such
change in phraseology and form (but not in substance) may be made in the
Securities thereafter to be issued as may be appropriate.

     SECTION 8.03. Evidence to be Furnished to the Trustee

     The Trustee, subject to the provisions of Sections 6.01 and 6.03, may
receive and rely upon an Officers' Certificate and an Opinion of Counsel as
conclusive evidence that any consolidation, merger, sale or conveyance, and any
such assumption complies with the provisions of this Article Eight.

     SECTION 9.01. Supplemental Indentures without Consent of Holders

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

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

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

     (c) to add any additional Events of Default for the benefit of the Holders
of all or any series of Securities (and if such additional Events of Default are
to be for the benefit of less than all series of Securities, stating that such
additional Events of Default are expressly being included solely for the benefit
of the


                                       62

<PAGE>

relevant series) or to surrender any right or power herein conferred upon the
Company; or

     (d) to add to or change any of the provisions of this Indenture to such
extent as shall be necessary to permit or facilitate the issuance of Securities
in bearer form, registrable or not registrable as to principal, and with or
without interest coupons, or permit or facilitate the issuance of Securities in
uncertificated form; or

     (e) to add to, change or eliminate any of the provisions of this Indenture
in respect of one or more series of Securities, provided that any such addition,
change or elimination (A) shall neither (i) apply to Securities of any series
created prior to the execution of such supplemental indenture and entitled to
the benefit of such provision nor (ii) modify the rights of the Holder of such
Securities with respect to such provision or (B) shall become effective only
when there is no such Security Outstanding; or

     (f) to secure the Securities; or

     (g) to establish the form or terms of Securities of any series as permitted
by Sections 2.01 and 3.01; or

     (h) to evidence and provide for the acceptance of appointment hereunder by
a successor Trustee with respect to the Securities of one or more series and to
add to or change any of the provisions of this Indenture as shall be necessary
to provide for and facilitate the administration of the trusts hereunder by more
than one Trustee, pursuant to the requirements of Section 6.11(b); or

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

     SECTION 9.02. Supplemental Indentures with Consent of Holders

     With the consent of the Holders of not less than a majority in principal
amount of the Outstanding Securities of each series affected by such
supplemental indenture voting as one class, by Act of said Holders delivered to
the Company and the Trustee, the Company, when authorized by a Board Resolution,
and the Trustee may enter into an indenture or indentures supplemental hereto
for the purpose of adding any provisions to or changing in any manner or
eliminating any of the provisions of this Indenture or of modifying in any
manner the rights of the


                                       63

<PAGE>

Holders of Securities of such series under the Indenture; provided, however,
that no such supplemental indenture shall, without the consent of the Holder of
each Outstanding Security affected thereby,

     (a) change the Stated Maturity of the principal of, or any installment of
principal of or interest on, any Security, or reduce the principal amount
thereof or the rate of interest thereon or any premium payable upon the
redemption thereof, or reduce the amount of the principal of an Original Issue
Discount Security that would be due and payable upon a declaration of
acceleration of the Maturity thereof pursuant to Section 5.02, or change any
Place of Payment where, or the coin or currency in which, any Security or any
premium or the interest thereon is payable, or impair the right to institute
suit for the enforcement of any such payment on or after the Stated Maturity
thereof (or, in the case of redemption, on or after the Redemption Date), or

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

     (c) modify any of the provisions of this Section or Section 5.13, except to
increase any such percentage or to provide that certain other provisions of this
Indenture cannot be modified or waived without the consent of the Holder of each
Outstanding Security affected thereby; provided, however, that this clause shall
not be deemed to require the consent of any Holder with respect to changes in
the references to "the Trustee" and concomitant changes in this Section, or the
deletion of this proviso, in accordance with the requirements of Sections
6.11(b) and 9.01(h).

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

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

     SECTION 9.03. Execution of Supplemental Indentures

     In executing, or accepting the additional trusts created by, any
supplemental indenture permitted by this Article or the modifications thereby of
the trusts created by this Indenture, the Trustee shall receive, and (subject to
Section 6.01) shall be fully protected in relying upon, an Officers' Certificate
and an Opinion of Counsel stating that the execution of such supplemental
indenture is authorized or permitted by this Indenture. The Trustee may, but
shall not be obligated to, enter into any such supplemental indenture which
affects the Trustee's own rights, duties or immunities under this Indenture or
otherwise.

     SECTION 9.04. Effect of Supplemental Indentures

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

     SECTION 9.05. Conformity with Trust Indenture Act

conform to the requirements of the Trust Indenture Act as then in effect.

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

                                    COVENANTS

     SECTION 10.01. Payment of Principal, Premium and Interest

     The Company covenants and agrees for the benefit of each series of
Securities that it will duly and punctually pay or cause to be paid the
principal of (and premium, if any) and any interest on each of the Securities of
that series in accordance with the terms of the Securities and this Indenture.

     SECTION 10.02. Maintenance of Office or Agency

     The Company will maintain in each Place of Payment for any series of
Securities an office or agency where Securities of that series may be presented
or surrendered for payment, 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. The Company will give prompt written notice to the Trustee and
the Holders of the location, and any change in the location, of 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 and surrenders of Securities of that series and notices and
demands may be made or served at the Corporate Trust Office of the Trustee, and
the Company hereby appoints the Trustee as its agent to receive all such
presentations, surrenders, notices and demands.

     The Company may also 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 such purposes and may from time to time rescind such
designation; 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 each Place of Payment for Securities of any series for such purposes. The
Company will give prompt written notice to the Trustee and the Holders of any
such designation or rescission and of any change in the location of any such
other office or agency.

     SECTION 10.03. Money for Securities Payments to be Held in Trust

     (a) If the Company shall appoint a paying agent other than the Trustee with
respect to the Securities of any series, it will cause such paying agent to
execute and deliver to the Trustee an instrument in which such agent shall agree
with the Trustee, subject to the provisions of this Section 10.03:


                                       66

<PAGE>

          (i) that it will hold all sums held by it as such agent for the
     payment of the principal of and premium, if any, or interest, if any, on
     the Securities of such series (whether such sums have been paid to it by
     the Company or by any other obligor on the Securities of such series) in
     trust for the benefit of the holders of the Securities of such series;

          (ii) that it will give the Trustee notice of any failure by the
     Company (or by any other obligor on the Securities of such series) to make
     any payment of the principal of and premium, if any, or interest, if any,
     on the Securities of such series when the same shall be due and payable;
     and

          (iii) 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.

     (b) If the Company shall at any time act as its own Paying Agent it will,
on or before each due date of the principal of (and premium, if any) or
interest, if any, on the Securities of any series, set aside, segregate and hold
in trust for the benefit of the Persons entitled thereto a sum sufficient to pay
such principal (and premium, if any) or interest so becoming due and will notify
the Trustee of any failure to take such action and of any failure by the Company
(or by any other obligor under the Securities of such series) to make any
payment of the principal of and premium, if any, or interest, if any, on the
Securities of such series when the same shall become due and payable.

     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
money.

     Any money deposited with the Trustee (except pursuant to Section 4.02), or
any Paying Agent, or then held by the Company, in trust for the payment of the
principal of (and premium, if any) or interest on any Security of any series and
remaining unclaimed for two years after such principal (and premium, if any) or
interest has become due and payable shall be paid to the Company on Company
Request, or (if then held by the Company) shall be discharged from such trust;
and the Holder of such Security shall thereafter, as an unsecured general
creditor, look only to the Company for payment thereof, and all liability of the
Trustee or such Paying Agent with respect to such trust money, and all liability
of the Company as


                                       67

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 a newspaper published in
the English language, customarily published on each Business Day and of general
circulation in the Borough of Manhattan, The City of New York, 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 10.04. Certificate of Officers of the Company

     On or before April 1 of each year beginning with the year 2001, so long as
Securities of any series are Outstanding hereunder, the Company will file with
the Trustee an Officers' Certificate, one of the signers of which shall be the
principal financial officer, the principal accounting officer or the principal
executive officer of the Company, stating whether or not to the best knowledge
of the signers thereof the Company is in default in the performance and
observance of any of the terms, provisions and conditions of this Indenture,
and, if the Company shall be in default, specifying all such defaults and the
nature and status thereof of which they may have knowledge. For purposes of this
paragraph, any such default shall be determined without regard to any period of
grace or requirement of notice provided in this Indenture.

                                   ARTICLE 11
                            REDEMPTION OF SECURITIES

     SECTION 11.01. Applicability of Article

     Any Securities that are redeemable before their Stated Maturity shall be
redeemable in accordance with their terms and (except as otherwise specified as
contemplated by Section 3.01 for any Securities) in accordance with this
Article.

     SECTION 11.02. Election to Redeem; Notice to Trustee

     The election of the Company to redeem any Securities shall be evidenced by
a Board Resolution. In case of any redemption at the election of the Company of
less than all the Securities of any series, the Company shall, at least 60 days
prior to the Redemption Date fixed by the Company (unless a shorter notice shall
be satisfactory to the Trustee), notify the Trustee of such Redemption Date, of
the tenor, if applicable, of the Securities to be redeemed, and of the principal
amount of Securities to be redeemed. In the case of any redemption of Securities
prior to


                                       68

<PAGE>

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 11.03. Selection by Trustee of Securities to be Redeemed

     If less than all the Securities of any series are to be redeemed (unless
all of the Securities of a specified tenor are to be redeemed), the particular
Securities to be redeemed shall be selected not more than 60 days prior to the
Redemption Date by the Trustee, from the Outstanding Securities of such series
not previously called for redemption, by such method as the Trustee shall deem
fair and appropriate and which may provide for the selection for redemption of
portions (equal to the minimum authorized denomination for Securities of that
series or any 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. If less than all of the Securities of such series and
of a specified tenor are to be redeemed, the particular Securities to be
redeemed shall be selected not more than 45 days prior to the Redemption Date by
the Trustee, from the Outstanding Securities of such series and specified tenor
not previously called for redemption in accordance with the preceding sentence.

     The Trustee shall promptly notify the Company 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 Securities redeemed or to be redeemed only in part, to the portion
of the principal amount of such Securities which has been or is to be redeemed.

     SECTION 11.04. Notice of Redemption

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

     All notices of redemption shall identify the Securities to be redeemed
(including by CUSIP number, if applicable) and shall state:

     (a) the Redemption Date,

     (b) the Redemption Price,


                                       69

<PAGE>

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

     (d) that on the Redemption Date the Redemption Price will become due and
payable upon each such Security to be redeemed and, if applicable, that interest
thereon will cease to accrue on and after said date,

     (e) the place or places where such Securities are to be surrendered for
payment of the Redemption Price, and

     (f) that the redemption is for a sinking fund, if such is the case.

     Notice of redemption of Securities to be redeemed at the election of the
Company shall be given by the Company or, at the Company's request, by the
Trustee in the name and at the expense of the Company and shall be irrevocable.
The notice of redemption mailed in the manner herein provided shall be
conclusively presumed to have been duly given whether or not the Holder receives
such notice. In any case, failure to give such notice by mail or any defect in
the notice to the Holder of any Security shall not affect the validity of the
proceeding for the redemption of any other Security.

     SECTION 11.05. Deposit of Redemption Price

     Prior to 10:00 a.m., New York City time, on 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 10.03) an amount of money sufficient to pay the Redemption
Price of, and accrued interest on, all the Securities which are to be redeemed
on that date.

     SECTION 11.06. Securities Payable on Redemption Date

     Notice of redemption having been given as aforesaid, the Securities so to
be redeemed shall, on the Redemption Date, become due and payable at the
Redemption Price therein specified, and from and after such date (unless the
Company shall default in the payment of the Redemption Price and accrued
interest), such Securities shall cease to bear interest. Upon surrender of any
such Security for redemption in accordance with said notice, such Security shall
be paid by the Company at the Redemption Price, together with accrued interest
to the Redemption Date; provided, however, that installments of interest whose
Stated Maturity is on or prior to the Redemption Date shall be payable to the


                                       70

<PAGE>

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 3.07.

     If any Security called for redemption shall not be so paid upon surrender
thereof for redemption, the principal (and premium, if any) shall, until paid,
bear interest from the Redemption Date at the rate prescribed therefor in the
Security.

     SECTION 11.07. Securities Redeemed in Part

     Any Security which is to be redeemed only in part 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 and of like tenor, 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. If a Security in permanent global form is so
surrendered, the Company shall execute, and the Trustee shall authenticate and
deliver to the Depositary for such Security in permanent global form, without
service charge to the Holder, a new Security in permanent global form in a
denomination equal to and in exchange for the unredeemed portion of the
principal of the Security in permanent global form so surrendered.

                                   ARTICLE 12
                                  SINKING FUNDS

     SECTION 12.01. Applicability of Article

     The provisions of this Article shall be applicable to any sinking fund for
the retirement of Securities of a series except as otherwise specified as
contemplated by Section 3.01 for Securities of such series.

     The minimum amount of any sinking fund payment provided for by the terms of
Securities of any series is herein referred to as a "mandatory sinking fund
payment," and any payment in excess of such minimum amount provided for by the
terms of Securities of any series is herein referred to as an "optional sinking
fund payment." If provided for by the terms of Securities of any series, the
cash amount of any sinking fund payment may be subject to reduction as


                                       71

<PAGE>

provided in Section 12.02. Each sinking fund payment shall be applied to the
redemption of Securities of any series as provided for by the terms of
Securities of such series.

     SECTION 12.02. Satisfaction of Sinking Fund Payments with Securities

     The Company (a) may deliver Outstanding Securities of a series (other than
any previously called for redemption) and (b) may apply as a credit Securities
of a series which have been redeemed either at the election of the Company
pursuant to the terms of such Securities or through the application of permitted
optional sinking fund payments pursuant to the terms of such Securities, in each
case in satisfaction of all or any part of any sinking fund payment with respect
to the Securities of such series required to be made pursuant to the terms of
such Securities as provided for by the terms of such Series; provided that the
Securities to be so credited have not been previously so credited. The
Securities to be so credited shall be received and credited for such purpose by
the Trustee at the Redemption Price, as specified in the Securities to be so
redeemed, for redemption through operation of the sinking fund and the amount of
such sinking fund payment shall be reduced accordingly.

     SECTION 12.03. Redemption of Securities for Sinking Fund

     Not less than 60 days prior to each sinking fund payment date for any
series of Securities, the Company will deliver to the Trustee an Officers'
Certificate specifying the amount of the next ensuing sinking fund payment for
that series pursuant to the terms of such Securities, the portion thereof, if
any, which is to be satisfied by payment of cash and the portion thereof, if
any, which is to be satisfied by delivering and crediting Securities of that
series pursuant to Section 12.02 stating that such Securities have not been
previously used as a credit against any sinking fund payment and will also
deliver to the Trustee any Securities to be so delivered. Not less than 30 days
before each such sinking fund payment date the Trustee shall select the
Securities to be redeemed upon such sinking fund payment date in the manner
specified in Section 11.03 and cause notice of the redemption thereof to be
given in the name of and at the expense of the Company in the manner provided in
Section 11.04. Such notice having been duly given, the redemption of such
Securities shall be made upon the terms and in the manner stated in Sections
11.05, 11.06 and 11.07.

                           SUBORDINATION OF SECURITIES

     SECTION 13.01. Agreement to Subordinate

     The Company covenants and agrees, and each holder of Securities issued
hereunder by his acceptance thereof likewise covenants and agrees, that all
Securities issued hereunder shall be issued subject to the provisions of this
Article; and each person holding any Security, whether upon original issue or
upon transfer or assignment thereof, accepts and agrees to be bound by such
provisions. The provisions of this Article are made for the benefit of the
Holders of Senior Indebtedness, and such Holders shall, at any time, be entitled
to enforce such provisions against the Company or any Holders.

     All Securities issued hereunder shall, to the extent and in the manner
hereinafter in this Article set forth, be subordinate and junior in right of
payment to the prior payment in full of all Senior Indebtedness.

     SECTION 13.02. No Payment on Securities if Senior Indebtedness in Default

     No payment on account of principal, premium, if any, sinking funds or
interest on the Securities shall be made unless full payment of amounts then due
for principal, premium, if any, sinking funds and interest on all Senior
Indebtedness has been made or duly provided for. No payment (including the
making of any deposit in trust with the Trustee in accordance with Section 4.01)
on account of principal, premium, if any, sinking funds or interest on the
Securities shall be made if, at the time of such payment or immediately after
giving effect thereto, (i) there shall exist a default in the payment of
principal, premium, if any, sinking funds or interest with respect to any Senior
Indebtedness, or (ii) there shall have occurred an event of default (other than
a default in the payment of principal, premium, if any, sinking funds or
interest) with respect to any Senior Indebtedness, as defined therein or in the
instrument under which the same is outstanding, permitting the holders thereof
to accelerate the maturity thereof, and such event of default shall not have
been cured or waived or shall not have ceased to exist. The foregoing provision
shall not prevent the Trustee from making payments on the Securities from monies
or securities deposited with the Trustee pursuant to the terms of Section 4.01
if at the time such deposit was made or immediately after giving effect thereto
the conditions in (i) or (ii) of this Section did not exist.

     SECTION 13.03. Priority of Senior Indebtedness

     In the event of any insolvency or bankruptcy proceedings, and any
receivership, liquidation, reorganization under the Federal Bankruptcy Code or
any other similar applicable Federal or state law, or other similar proceedings
in connection therewith, relative to the Company or to its creditors, as such,
or to its property, and in the event of any proceedings for voluntary
liquidation, dissolution or other winding up of the Company or assignment for
the benefit of creditors or any other marshalling of assets of the Company,
whether or not involving insolvency or bankruptcy, then the holders of Senior
Indebtedness shall be entitled to receive payment in full of all principal of
and premium, if any, and interest on all Senior Indebtedness including interest
on such Senior Indebtedness after the date of filing of a petition or other
action commencing such proceeding before the Holders of the Securities are
entitled to receive any payment on account of the principal of or premium, if
any, or interest on the Securities (except that Holders of Securities shall be
entitled to receive such payments from monies or securities deposited with the
Trustee pursuant to the terms of Section 4.01 if at the time such deposit was
made or immediately after giving effect thereto the conditions in (i) or (ii) of
Section 13.02 did not exist), and any payment or distribution of any kind or
character which may be payable or deliverable in any such proceedings in respect
of the Securities, except securities which are subordinate and junior in right
of payment to the payment of all Senior Indebtedness then outstanding, shall be
paid by the person making such payment or distribution directly to the holders
of Senior Indebtedness to the extent necessary to make payment in full of all
Senior Indebtedness, after giving effect to any concurrent payment or
distribution to the holders of Senior Indebtedness. In the event that any
payment or distribution of cash, property or securities shall be received by the
Trustee or the Holders of the Securities in contravention this Section before
all Senior Indebtedness is paid in full, or provision made for the payment
thereof, such payment or distribution shall be held in trust for the benefit of
and shall be paid over to the holders of such Senior Indebtedness or their
representative or representatives, or to the trustee or trustees under any
indenture under which any instrument evidencing any of such Senior Indebtedness
may have been issued, as their respective interests may appear, to the extent
necessary to pay in full all Senior Indebtedness remaining unpaid, after giving
effect to any concurrent payment or distribution to the holders of such Senior
Indebtedness.

     In the event that any Security is declared due and payable before its
expressed maturity because of the occurrence of an Event of Default (under
circumstances when the provisions of the first paragraph of this Section shall
not be applicable), the holders of the Senior Indebtedness outstanding at the
time the Securities of such series so become due and payable because of such
occurrence of such an Event of Default shall be entitled to receive payment in
full of all


                                       74

<PAGE>

principal of and premium, if any, and interest on all Senior Indebtedness
before the Holders of the Securities of such series are entitled to receive any
payment on account of the principal of or premium, if any, or interest on the
Securities of such series except that Holders of Securities of such series
shall be entitled to receive payments from monies or securities deposited with
the Trustee pursuant to the terms of Section 4.01, if at the time of such
deposit no Security of such series had been declared due and payable before its
expressed maturity because of the occurrence of an Event of Default.

     Nothing in this Section shall apply to claims of, or payments to, the
Trustee under or pursuant to Section 6.07.

     SECTION 13.04. Company to Give Notice of Certain Events; Reliance by
Trustee

     The Company shall give prompt written notice to the Trustee of any
insolvency or bankruptcy proceedings, any receivership, liquidation,
reorganization under the Federal Bankruptcy Code or any other similar applicable
Federal or state law, or similar proceedings and any proceedings for voluntary
liquidation, dissolution or winding up of the Company within the meaning of this
Article. The Trustee shall be entitled to assume that no such event has occurred
unless the Company or any one or more holders of Senior Indebtedness or any
trustee therefor has given such notice together with proof satisfactory to the
Trustee of such holding of Senior Indebtedness or the authority of such Trustee.
Upon any payment or distribution of assets of the Company referred to in this
Article, the Trustee, in the absence of its negligence or bad faith, and any
Holder of a Security shall be entitled to rely conclusively upon a certificate
of the receiver, trustee in bankruptcy, liquidation trustee, agent or other
person making such payment or distribution, delivered to the Trustee or to the
Holders of Securities, for the purpose ascertaining the persons entitled to
participate in such distribution, the holders of the Senior Indebtedness and
other indebtedness of the Company, the amount thereof or payable thereon, the
amount or amounts paid or distributed thereon and all other facts pertinent
thereto or to this Article. In the event that the Trustee determines, in good
faith, that further evidence is required with respect to the right of any person
as a holder of Senior Indebtedness to participate in any payment or distribution
pursuant to this Article, the Trustee may request such person to furnish
evidence to the reasonable satisfaction of the Trustee as to the amount of
Senior Indebtedness held by such person, as to the extent to which such person
is entitled to participate in such payment or distribution and as to other facts
pertinent to the rights of such person under this Article, and if such evidence
is not furnished, the Trustee may defer any payment to such person pending
judicial determination as to the right of such person to receive such payment.


                                       75

<PAGE>

     With respect to the holders of Senior Indebtedness, the Trustee undertakes
to perform or to observe only such covenants and obligation as are specifically
set forth in this Indenture and no implied covenants or obligations with respect
to holders of Senior Indebtedness shall be read into this Indenture against the
Trustee. The Trustee does not have any fiduciary duties to holders of Senior
Indebtedness and shall not be liable to any such holders if it shall mistakenly
pay over or distribute to Holders of Securities or the Company or any other
person, moneys or assets to which any holder of Senior Indebtedness shall be
entitled by virtue of this Article or otherwise.

     Nothing in this Section shall apply to claims of, or payments to, the
Trustee under or pursuant to Section 6.07.

     SECTION 13.05. Subrogation of Securities

     Subject to the payment in full of all Senior Indebtedness, the Holders of
the Securities shall be subrogated to the rights of the holders of Senior
Indebtedness to receive payments or distributions of assets of the Company made
on the Senior Indebtedness until the principal of and premium, if any, and
interest on the Securities shall be paid in full; and, for the purposes of such
subrogation, no payments or distributions to the holders of Senior Indebtedness
of any cash, property or securities to which the Holders of the Securities or
the Trustee would be entitled except for the provisions of this Article, and no
payment over pursuant to the provisions of this Article to the holders of Senior
Indebtedness by Holders of the Securities, or by the Trustee, shall, as between
the Company, its creditors other than the holders of Senior Indebtedness, and
the Holders of Securities, be deemed to be a payment by the Company to or on
account of Senior Indebtedness, and no payments or distributions to the Trustee
or the Holders of the Securities of cash, property or securities payable or
distributable to the holders of the Senior Indebtedness to which the Trustee or
the Holders of the Securities shall become entitled pursuant to the provisions
of this Section, shall, as between the Company, its creditors other than the
holders of Senior Indebtedness, and the Holders of the Securities, be deemed to
be a payment by the Company to the Holders of or on account of the Securities.

     SECTION 13.06. Company Obligation to Pay Unconditional

     The provisions of this Article are solely for the purpose of defining the
relative rights of the holders of Senior Indebtedness on the one hand, and the
Holders of the Securities on the other hand, and nothing herein shall impair, as
between the Company and the Holders of the Securities, the obligation of the
Company, which is unconditional and absolute, to pay to the Holders thereof the
principal thereof and premium, if any, and interest thereon in accordance with
the


                                       76

<PAGE>

terms of the Securities and this Indenture nor shall anything herein prevent the
Holders of the Securities or the Trustee from exercising all remedies otherwise
permitted by applicable law or under the Securities and this Indenture upon
default under the Securities and this Indenture, subject to the rights of
holders of Senior Indebtedness under the provisions of this Article to receive
cash, property or securities otherwise payable or deliverable to the Holders of
the Securities.

     SECTION 13.07. Authorization of Holders of Securities to Trustee to Effect
Subordination

     Each Holder of Securities by his acceptance thereof authorizes the Trustee
in his behalf to take such action as may be necessary or appropriate to
effectuate the subordination as provided in this Article and appoints the
Trustee his attorney-in-fact for any and all such purposes.

     SECTION 13.08. Notice to Trustee of Facts Prohibiting Payments

     Notwithstanding any of the provisions of this Article or any other
provision of this Indenture, the Trustee shall not at any time be charged with
knowledge of the existence of any facts which would prohibit the making of any
payment of moneys to or by the Trustee, unless and until the principal office of
the Trustee shall have received written notice thereof from the Company or from
one or more holders of Senior Indebtedness or from any trustee therefor,
together with proof satisfactory to the Trustee of such holding of Senior
Indebtedness or the authority of such Trustee, and, prior to the receipt of any
such written notice, the Trustee, subject to the provisions of Section 6.01,
shall be entitled in all respects to assume that no such facts exist; provided,
that, if prior to the second business day preceding the date upon which by the
terms hereof any such moneys may become payable for any purpose (including,
without limitation, the payment of the principal of or premium, if any, or
interest on any Security), the Trustee shall not have received with respect to
such moneys the notice provided for in this Section, then, anything herein
contained to the contrary notwithstanding, the Trustee and any Paying Agent
shall have full power and authority to receive such moneys and to apply the same

name this Security (or one or more Predecessor Securities) is registered at the
close of business on the Regular Record Date for such interest, which shall be

or duly provided for will forthwith cease to be payable to the Holder on such
Regular Record Date and may either be paid to the Person in whose name this
Security (or one or more Predecessor Securities) is registered at the close of
business on a Special Record Date for the payment of such Defaulted Interest to
be fixed by the Trustee, notice whereof shall be given to Holders of Securities
of this series not less than 10 days prior to such Special Record Date, or be

principal of this Security shall not bear interest except in the case of a
default in payment of principal upon acceleration, upon redemption or at Stated
Maturity and in such case the overdue principal of this Security shall bear
interest at the rate of __% per annum (to the extent that the payment of such
interest shall be legally enforceable), which shall accrue from the date of such
default in payment to the date payment of such principal has been made or duly
provided for. Interest on any overdue principal that is not so paid on demand
shall bear interest at the rate of ___% per annum (to the extent that the
payment of such interest shall be legally enforceable), which shall accrue from
the date of such demand for payment to the date payment of such interest has

<PAGE>

     [The Indenture contains provisions for defeasance at any time of (a) the
entire indebtedness of this Security and (b) certain restrictive covenants, in
each case upon compliance by the Company with certain conditions set forth
therein, which provisions apply to this Security.]

     [If the Security is not an Original Issue Discount Security, --If an Event

continuing, the principal of the Securities of this series may be declared due
and payable in the manner and with the effect provided in the Indenture.]

     [If the Security is an Original Issue Discount Security, --If an Event of

Company and the rights of the Holders of the Securities of each series to be
affected under the Indenture at any time by the Company and the Trustee with the
consent of the Holders of a majority in principal amount of the Securities at
the time Outstanding of each series to be affected. The Indenture also contains
provisions permitting the Holders of specified percentages in principal amount
of the Securities of each series at the time Outstanding, on behalf of the
Holders of all Securities of such series, to waive compliance by the Company
with certain provisions of the Indenture and certain past defaults under the
Indenture and their consequences. Any such consent or waiver by the Holder of
this Security shall be conclusive and binding upon such Holder and upon all
future Holders of this Security and of any Security issued upon the registration
of transfer hereof or in exchange herefor or in lieu hereof, whether or not
notation of such consent or waiver is made upon this Security.

     As provided in and subject to the provisions of the Indenture, the Holder
of this Security shall not have the right to institute any proceeding with
respect to the Indenture or for the appointment of a receiver or trustee or for
any other remedy thereunder, unless such Holder shall have previously given the
Trustee written notice of a continuing Event of Default with respect to the
Securities of this series, the Holders of not less than 25% in principal amount
of the Securities


                                       A-8

<PAGE>

of this series at the time Outstanding shall have made written request to the
Trustee to institute proceedings in respect of such Event of Default as Trustee
and offered the Trustee reasonable indemnity, and the Trustee shall not have
received from the Holders of a majority in principal amount of Securities of
this series at the time Outstanding a direction inconsistent with such request,
and shall have failed to institute any such proceeding, for 60 days after
receipt of such notice, request and offer of indemnity. The foregoing shall not
apply to any suit instituted by the Holder of this Security for the enforcement
of any payment of principal hereof or any premium or interest hereon on or after
the respective due dates expressed herein.

     The indebtedness evidenced by this Security is, to the extent and in the
manner provided in the Indenture, expressly subordinate and subject in right of
payment to the prior payment in full of all Senior Indebtedness, whether
outstanding at the date of the Indenture or thereafter incurred, and this
Security is issued subject to the provisions of the Indenture with respect to
such subordination. Each Holder of this Security, by accepting the same, agrees
to and shall be bound by such provisions and authorizes the Trustee in his
behalf to take such action as may be necessary or appropriate to effectuate the
subordination so provided and appoints the Trustee his attorney-in-fact for such
purpose.

     No reference herein to the Indenture and no provision of this Security or
of the Indenture shall alter or impair the obligation of the Company, which is
absolute and unconditional, to pay the principal of (and premium, if any) and
interest on this Security herein provided, and at the times, place and rate, and
in the coin or currency, herein prescribed.

     As provided in the Indenture and subject to certain limitations therein set
forth, the transfer of this Security is registrable in the Security Register,
upon surrender of this Security for registration of transfer at the office or
agency of the Company in any place where the principal of (and premium, if any)
and interest on this Security are payable, duly endorsed by, or accompanied by a
written instrument of transfer in form satisfactory to the Company and the
Security Registrar duly executed by, the Holder hereof or his attorney duly
authorized in writing, and thereupon one or more new Securities of this series,
of authorized denominations and for the same aggregate principal amount, will be
issued to the designated transferee or transferees.

     The Securities of this series are issuable only in registered form without
coupons in denominations of $___ and any multiple thereof. As provided in the
Indenture and subject to certain limitations therein set forth, Securities of
this series are exchangeable for a like aggregate principal amount of Securities
of this


                                       A-9

<PAGE>

series of a different authorized denomination, as requested by the Holder
surrendering the same.

     No service charge shall be made for any such registration of transfer or
exchange, but the Company may require payment of a sum sufficient to cover any
tax or other governmental charge payable in connection therewith.

     Prior to due presentment of this 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 this Security is registered as the owner hereof for all
purposes, whether or not this Security be overdue, and neither the Company, the
Trustee nor any such agent shall be affected by notice to the contrary.

     All terms used in this Security which are defined in the Indenture shall
have the meanings assigned to them in the Indenture.
