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

      SECTION 104. Acts of Holders. (a) Any request, demand, authorization,
direction, notice, consent, waiver or other action provided by this Indenture to
be given or taken by Holders of the Outstanding Securities of all series or one
or more series, as the case may be, may be embodied in and evidenced by one or
more instruments of substantially similar tenor signed by such Holders in person
or by agents duly appointed in writing. If Securities of a series are issuable
as Bearer Securities, any request, demand, authorization, direction, notice,
consent, waiver or other action provided by this Indenture to be given or taken
by Holders of Securities of such series may, alternatively, be embodied in and
evidenced by the record of Holders of Securities of such series voting in favor
thereof, either in person or by proxies duly appointed in writing, at any
meeting of Holders of Securities of such series duly called and held in
accordance with the provisions of Article Fifteen, or a combination of such
instruments and any such record. Except as herein otherwise expressly provided,
such action shall become effective when such instrument or instruments or record
or both are delivered to the Trustee

                                       12
<PAGE>
and, where it is hereby expressly required, to the Company. Such instrument or
instruments and any such record (and the action embodied therein and evidenced
thereby) are herein sometimes referred to as the "Act" of the Holders signing
such instrument or instruments or so voting at any such meeting. Proof of
execution of any such instrument or of a writing appointing any such agent, or
of the holding by any Person of a Security, shall be sufficient for any purpose
of this Indenture and conclusive in favor of the Trustee and the Company and any
agent of the Trustee or the Company, if made in the manner provided in this
Section. The record of any meeting of Holders of Securities shall be proved in
the manner provided in Section 1506.

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

            (c) The ownership of Registered Securities shall be proved by the
Security Register. As to any matter relating to beneficial ownership interests
in any Global Security, the appropriate depository's records shall be
dispositive for purposes of this Indenture.

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

            (e) If the Company shall solicit from the Holders of Registered
Securities any request, demand, authorization, direction, notice, consent,
waiver or other Act, the Company may, at its option, in or pursuant to a Board
Resolution, fix in advance a record date for the determination of Holders
entitled to give such request, demand, authorization, direction, notice,
consent, waiver or other Act, but the Company shall have no obligation to do

                                       13
<PAGE>
so. Notwithstanding TIA Section 316(c), such record date shall be the record
date specified in or pursuant to such Board Resolution, which shall be a date
not earlier than the date 30 days prior to the first solicitation of Holders
generally in connection therewith and not later than the date such solicitation
is completed. If such a record date is fixed, such request, demand,
authorization, direction, notice, consent, waiver or other Act may be given
before or after such record date, but only the Holders of record at the close of
business on such record date shall be deemed to be Holders for the purposes of
determining whether Holders of the requisite proportion of Outstanding
Securities have authorized or agreed or consented to such request, demand,
authorization, direction, notice, consent, waiver or other Act, and for that
purpose the Outstanding Securities shall be computed as of such record date;
provided that no such authorization, agreement or consent by the Holders on such
record date shall be deemed effective unless it shall become effective pursuant
to the provisions of this Indenture not later than eleven months after the
record date.

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

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

                  (1) the Trustee by any Holder or by the Company shall be
      sufficient for every purpose hereunder if made, given, furnished or filed
      in writing to or with the Trustee at State Street Bank and Trust Company,
      Two International Place, Boston MA 02110, Attention: Corporate Trust
      Department; or

                  (2) the Company by the Trustee or by any Holder shall be
      sufficient for every purpose hereunder (unless otherwise herein expressly
      provided) if in writing and mailed, first class postage prepaid, to the
      Company addressed to it at the address of its principal office specified
      in the first paragraph of this Indenture or at any other address
      previously furnished in writing to the Trustee by the Company, Attention:
      Chief Financial Officer, or

                  (3) either the Trustee or the Company, by the other party,
      shall be sufficient for every purpose hereunder if given by facsimile
      transmission, receipt confirmed by telephone followed by an original copy
      delivered by guaranteed overnight courier; if to the Trustee at facsimile
      number (617) 664-5371; and if to the Company at facsimile number (408)
      554-9780.

      SECTION 106. Notice to Holders: Waiver. Where this Indenture provides for
notice of any event to Holders of Registered Securities by the Company or the
Trustee, such notice shall be sufficiently given (unless otherwise herein
expressly provided) if in writing and mailed, first-class postage prepaid, to
each such Holder affected by such event, at his address as it appears in the
Security Register, not later than the latest date, if any, and not earlier than
the earliest date, if any, prescribed for the giving of such notice. In any case
where notice to Holders of Registered Securities is given by mail, neither the
failure to mail such notice, nor any defect in any notice so mailed, to any
particular Holder shall affect the sufficiency of such notice with respect to
other Holders of Registered Securities or the sufficiency of any notice to
Holders of Bearer Securities given as provided herein. Any notice mailed to a
Holder in the manner herein prescribed shall be conclusively deemed to have been
received by such Holder, whether or not such Holder actually receives such
notice.

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

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

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

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

      Where this Indenture provides for notice in any manner, such notice may be
waived in writing by the Person entitled to receive such notice, either before
or after the event, and such

                                       15
<PAGE>
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.

      SECTION 107. Counterparts; Effect of Headings and Table of Contents. This
Indenture may be executed in any number of counterparts, each of which so
executed shall be deemed to be an original, but all such counterparts shall
together constitute but one and the same Indenture. The Article and Section
headings herein and the Table of Contents are for convenience only and shall not
affect the construction hereof.

      SECTION 108. 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 109. Severability Clause. In case any provision in this Indenture
or in any Security or coupon shall be held invalid, illegal or unenforceable,
the validity, legality and enforceability of the remaining provisions shall not
in any way be affected or impaired thereby.

      SECTION 110. Benefits of Indenture. Nothing in this Indenture or in the
Securities or coupons, express or implied, shall give to any Person, other than
the parties hereto, any Security Registrar, any Paying Agent, any Authenticating
Agent and their successors hereunder and the Holders any benefit or any legal or
equitable right, remedy or claim under this Indenture.

      SECTION 111. Governing Law. This Indenture and the Securities and coupons
shall be governed by and construed in accordance with the law of the State of
New York. This Indenture is subject to the provisions of the TIA that are
required to be part of this Indenture and shall, to the extent applicable, be
governed by such provisions.

      SECTION 112. Legal Holidays. In any case where any Interest Payment Date,
Redemption Date, Repayment Date, sinking fund payment date, Stated Maturity or
Maturity of any Security or the last date on which a Holder has the right to
exchange a Security shall not be a Business Day at any Place of Payment, then
(notwithstanding any other provision of this Indenture or any Security or coupon
other than a provision in the Securities of any series which specifically states
that such provision shall apply in lieu hereof), payment of interest or
principal (and premium or Make-Whole Amount, if any) or exchange of such
security need not be made at such Place of Payment on such date, but (except as
otherwise provided in the supplemental indenture with respect to such Security)
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, Redemption
Date, Repayment Date or sinking fund payment date, or at the Stated Maturity or
Maturity, or on such last day for exchange, provided that no interest shall
accrue on the amount so payable for the period from and after such Interest
Payment Date, Redemption Date, Repayment Date, sinking fund payment date, Stated
Maturity or Maturity, as the case may be.

      SECTION 113. Immunity of Stockholders, Directors, Officers and Agents of
the Company. No recourse under or upon any obligation, covenant or agreement
contained in this Indenture, or in any Security, or because of any indebtedness
evidenced thereby, shall be had against any past, present or future stockholder,
employee, officer or director, as such, of the Company or of any successor,
either directly or through the Company or any successor, under any rule of law,
statute or constitutional provision or by the enforcement of any assessment or
by any legal or equitable proceeding or otherwise, all such liability being
expressly waived and released by the acceptance of the Securities by the Holders
and as part of the consideration for the issue of the Securities.

      SECTION 114. Conflict with Trust Indenture Act. If any provision hereof
limits, qualifies or conflicts with another provision hereof which is required
or deemed to be included in this Indenture by any of the provisions of the Trust
Indenture Act, such required provision shall control. If any provision of this
Indenture modifies or excludes any provision of the Trust Indenture Act that may
be so modified or excluded, the latter provision shall be deemed to apply to
this Indenture as so modified or to be excluded, as the case may be.

                         ARTICLE TWO - SECURITIES FORMS

      SECTION 201. Forms of Securities. The Registered Securities, if any, of
each series and the Bearer Securities, if any, of each series and related
coupons shall be substantially in the form of Exhibit A hereto or in such other
form as shall be established in one or more indentures supplemental hereto or
approved from time to time by or pursuant to a Board Resolution in accordance
with Section 301, shall have such appropriate insertions, omissions,
substitutions and other variations as are required or permitted by this
Indenture or any indenture supplemental hereto, and may have such letters,
numbers or other marks of identification or designation and such legends or
endorsements placed thereon as the Company may deem appropriate and as are not
inconsistent with the provisions of this Indenture, or as may be required to
comply with any law or with any rule or regulation made pursuant thereto or with
any rule or regulation of any stock exchange on which the Securities may be
listed, or to conform to usage.

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

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

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

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

                                  [__________________________________],
                                    as Trustee

Dated: ______________             By:__________________________________________
                                                  Authorized Signatory

      SECTION 203. Securities Issuable in Global Form. If Securities of or
within a series are issuable in the form of one or more Global Securities, then,
notwithstanding clause (8) of Section 301 and the provisions of Section 302, any
such Global Security or Securities may provide that it or they shall represent
the aggregate amount of all Outstanding Securities of such series (or such
lesser amount as is permitted by the terms thereof) from time to time endorsed
thereon and may also provide that the aggregate amount of Outstanding Securities
of such series represented thereby may from time to time be increased or
decreased to reflect exchanges. Any endorsement of any Global Security to
reflect the amount, or any increase or decrease in the amount, or changes in the
rights of Holders thereof, of Outstanding Securities represented thereby shall
be made (or caused to be made) by the Trustee in such manner or by such Person
or Persons as shall be specified therein or in the Company Order to be delivered
to the Trustee pursuant to Section 303 or 304. Subject to the provisions of
Section 303 and, if applicable, Section 304, the Trustee shall deliver and
redeliver any Global Security in permanent global form in the manner and upon
instructions given by the Person or Persons specified therein or in the
applicable Company Order. If a Company Order pursuant to Section 303 or 304 has
been, or simultaneously is, delivered, any instructions by the Company with
respect to endorsement or delivery or redelivery of a Global Security shall be
in writing but need not comply with Section 102 and need not be accompanied by
an Opinion of Counsel.

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

      Notwithstanding the provisions of Section 307, unless otherwise specified
as contemplated by Section 301, payment of principal of and any premium or
Make-Whole

                                       18
<PAGE>
Amount, if any, and interest on any Global Security in permanent global form
shall be made to the registered Holder thereof.

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

      Any Global Security authenticated and delivered hereunder shall bear a
legend in substantially the following form:

            "This Security is a Global Security within the meaning set forth in
            the Indenture hereinafter referred to and is registered in the name
            of a Depository or a nominee of a Depository. This Security is
            exchangeable for Securities registered in the name of a person other
            than the Depository or its nominee only in the limited circumstances
            described in the Indenture, and may not be transferred except as a
            whole by the Depository to a nominee of the Depository or by a
            nominee of the Depository to the Depository or another nominee of
            the Depository or by the Depository or its nominee to a successor
            Depository or its nominee."

      Company;

                  (10) The obligation, if any, of the Company to redeem, repay

      assessment or governmental charge and, if so, whether the Company will
      have the option to redeem such Securities in lieu of making such payment;

                  (21) If the Securities of such series are to be issuable in
      definitive form (whether upon original issue or upon exchange of a
      temporary Security of such series) only upon receipt of certain
      certificates or other documents or satisfaction of other conditions, then

      and delivery of a supplemental indenture as provided therein); and

                  (23) Any other terms of the series (which terms shall not be

                                       22
<PAGE>
      All Securities of any one series and the coupons appertaining to any
Bearer Securities of such series shall be substantially identical except, in the
case of Registered Securities, as to denomination and except as may otherwise be
provided in or pursuant to such Board Resolution (subject to Section 303) and
set forth in such Officers' Certificate or in any such indenture supplemental
hereto. All Securities of any one series need not be issued at the same time
and, unless otherwise provided, a series may be reopened, without the consent of
the Holders, for issuances of additional Securities of such series.

      If any of the terms of the Securities of any series are established by
action taken pursuant to one or more Board Resolutions, a copy of an appropriate
record of such action(s) 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 Officers' Certificate setting forth the terms of the Securities
of such series.

      SECTION 302. Denominations. The Securities of each series shall be
issuable in such denominations as shall be specified as contemplated by Section
301. With respect to Securities of any series denominated in Dollars, in the
absence of any such provisions with respect to the Securities of any series, the
Securities of such series, other than Global Securities (which may be of any
denomination), shall be issuable in denominations of $1,000 and any integral
multiple thereof.

      SECTION 303. Execution, Authentication, Delivery and Dating. The
Securities and any coupons appertaining thereto shall be executed on behalf of
the Company by its Chairman of the Board, its President or one of its Vice
Presidents, under its corporate seal reproduced thereon, and attested by its
Secretary or one of its Assistant Secretaries. The signature of any of these
officers on the Securities and coupons may be manual or facsimile signatures of
the present or any future such authorized officer and may be imprinted or
otherwise reproduced on the Securities.

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

      At any time and from time to time after the execution and delivery of this
Indenture, the Company may deliver Securities of any series, together with any
coupon appertaining thereto, executed by the Company to the Trustee for
authentication, together with a Company Order for the authentication and
delivery of such Securities (accompanied by a copy of the Board Resolution and
the Officers' Certificate or supplemental indenture contemplated by Section
301), and the Trustee in accordance with the Company Order shall authenticate
and deliver such Securities; provided, however, that, in connection with its
original issuance, no Bearer Security shall be mailed or otherwise delivered to
any location in the United States; and

                                       23
<PAGE>
provided further that, unless otherwise specified with respect to any series of
Securities pursuant to Section 301, a Bearer Security may be delivered in
connection with its original issuance only if the Person entitled to receive
such Bearer Security shall have furnished a certificate to Euroclear or CEDEL,
as the case may be, in the form set forth in Exhibit B-1 to this Indenture or
such other certificate as may be specified by the Company with respect to any
series of Securities pursuant to Section 301, dated no earlier than 15 days
prior to the earlier of the date on which such Bearer Security is delivered and
the date on which any temporary Security first becomes exchangeable for such
Bearer Security in accordance with the terms of such temporary Security and this
Indenture. If any Security shall be represented by a permanent global Bearer
Security, then, for purposes of this Section and Section 304, the notation of a
beneficial owner's interest therein upon original issuance of such Security or
upon exchange of a portion of a temporary Global Security shall be deemed to be
delivery in connection with its original issuance of such beneficial owner's
interest in such permanent Global Security. Except as permitted by Section 306,
the Trustee shall not authenticate and deliver any Bearer Security unless all
appurtenant coupons for interest then matured have been detached and canceled.

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

            (i) an Opinion of Counsel stating that

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

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

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

                                       24
<PAGE>
            enforcement of creditors' rights generally and to general equitable
            principles; and

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

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

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

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

      No Security or coupon shall be entitled to any benefit under this
Indenture or be valid or obligatory for any purpose unless there appears on such
Security or Security to which such coupon appertains a certificate of
authentication substantially in the form provided for herein duly executed by
the Trustee (subject to Section 611) by manual signature of an authorized
signatory, and such certificate upon any Security shall be conclusive evidence,
and the only evidence, that such Security has been duly authenticated and
delivered hereunder and is entitled to the benefits of this Indenture.
Notwithstanding the foregoing, if any Security (including a Global Security)
shall have been authenticated and delivered hereunder but never issued and sold
by the Company, and the Company shall deliver such Security to the Trustee for
cancellation as provided in Section 309 together with a written statement (which
need not comply with Section 102 and need not be accompanied by an Opinion of
Counsel) stating that such Security has never been issued and sold by the
Company, for all purposes of this Indenture such Security shall be deemed never
to have been authenticated and delivered hereunder and shall never be entitled
to the benefits of this Indenture.

      SECTION 304. Temporary Securities.

      (a) Pending the preparation of definitive Securities of any series, the
Company may execute, and upon Company Order the Trustee shall authenticate and
deliver, temporary Securities which are printed, lithographed, typewritten,
mimeographed or otherwise produced, in any authorized denomination,
substantially of the tenor of the definitive Securities in lieu of which they
are issued, in registered form, or, if authorized, in bearer form with one or
more coupons or without coupons, and with such appropriate insertions,
omissions, substitutions and other variations as the officers executing such
Securities may determine, as conclusively evidenced by their execution of such
Securities. In the case of Securities of any series, such temporary Securities
may be in global form.

      Except in the case of temporary Global Securities (which shall be
exchanged as otherwise provided herein or as otherwise provided in or pursuant
to a Board Resolution or supplemental indenture pursuant to Section 301), if
temporary Securities of any series are issued, the Company will cause definitive
Securities of that series to be prepared without unreasonable delay. After the
preparation of definitive Securities of such series, the temporary Securities of
such series shall be exchangeable for definitive Securities of such series upon
surrender of the temporary Securities of such series at the office or agency of
the Company in a Place of Payment for that series, without charge to the Holder.
Upon surrender for cancellation of any one or more temporary Securities of any
series (accompanied by any non-matured coupons appertaining thereto), the
Company shall execute and the Trustee shall authenticate and deliver in exchange
therefor a like principal amount of definitive Securities of the same series of
authorized denominations; provided, however, that no definitive Bearer Security
shall be delivered in exchange for a temporary Registered Security; and provided
further that a definitive Bearer Security shall be delivered in exchange for a
temporary Bearer Security only in compliance with the conditions set forth in
Section 303. Until so exchanged, the temporary Securities of any series shall in
all respects be entitled to the same benefits under this Indenture as definitive
Securities of such series.

      (b) Unless otherwise provided in or pursuant to a Board Resolution or
supplemental indenture pursuant to Section 301, the following provisions of this
Section 304(b) shall govern the exchange of temporary Securities other than
through the facilities of The Depository Trust Company. If any such temporary
Security is issued in global form, then such temporary Global Security shall,
unless otherwise provided therein, be delivered to the London office of a
depository or common depository upon and pursuant to written direction of the
Company (the "Common Depository"), for the benefit of Euroclear and CEDEL, for
credit to the respective accounts of the beneficial owners of such Securities
(or to such other accounts as they may direct).

      Without unnecessary delay but in any event not later than the date
specified in, or determined pursuant to the terms of, any such temporary Global
Security (the "Exchange Date"), the Company shall deliver to the Trustee
definitive Securities, in aggregate principal

                                       26
<PAGE>
amount equal to the principal amount of such temporary Global Security, executed
by the Company. On or after the Exchange Date, such temporary Global Security
shall be surrendered by the Common Depository to the Trustee, as the Company's
agent for such purpose, to be exchanged, in whole or from time to time in part,
for definitive Securities without charge, and the Trustee shall authenticate and
deliver, in exchange for each portion of such temporary Global Security, an
equal aggregate principal amount of definitive Securities of the same series of
authorized denominations and of like tenor as the portion of such temporary
Global Security to be exchanged. The definitive Securities to be delivered in
exchange for any such temporary Global Security shall be in bearer form,
registered form, permanent global bearer form or permanent global registered
form, or any combination thereof, as specified as contemplated by Section 301,
and, if any combination thereof is so specified, as requested by the beneficial
owner thereof (as directed by or pursuant to information provided by the Common
Depository); provided, however, that, unless otherwise specified in such
temporary Global Security, upon such presentation by the Common Depository, such
temporary Global Security shall be accompanied by a certificate dated the
Exchange Date or a subsequent date and signed by Euroclear as to the portion of
such temporary Global Security held for its account then to be exchanged and a
certificate dated the Exchange Date or a subsequent date and signed by CEDEL as
to the portion of such temporary Global Security held for its account then to be
exchanged, each in the form set forth in Exhibit A-2 to this Indenture or in
such other form as may be established pursuant to Section 301; and provided
further that definitive Bearer Securities shall be delivered in exchange for a
portion of a temporary Global Security only in compliance with the requirements
of Section 303.

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

      Until exchanged in full as hereinabove provided, the temporary Securities
of any series shall in all respects be entitled to the same benefits under this
Indenture as definitive Securities of the same series and of like tenor
authenticated and delivered hereunder, except that, unless

                                       27
<PAGE>
otherwise specified as contemplated by Section 301, interest payable on a
temporary Global Security on an Interest Payment Date for Securities of such
series occurring prior to the applicable Exchange Date shall be payable to
Euroclear and CEDEL on such Interest Payment Date upon delivery by Euroclear and
CEDEL to the Trustee of a certificate or certificates in the form set forth in
Exhibit B-2 to this Indenture (or in such other forms as may be established
pursuant to Section 301), for credit without further interest on or after such
Interest Payment Date to the respective accounts of Persons who are the
beneficial owners of such temporary Global Security on such Interest Payment
Date and who have each delivered to Euroclear or CEDEL, as the case may be, a
certificate dated no earlier than 15 days prior to the Interest Payment Date
occurring prior to such Exchange Date in the form set forth as Exhibit B-1 to
this Indenture (or in such other forms as may be established pursuant to Section
301). Notwithstanding anything to the contrary herein contained, the
certifications made pursuant to this paragraph shall satisfy the certification
requirements of the preceding two paragraphs of this Section 304(b) and of the
third paragraph of Section 303 of this Indenture and the interests of the
Persons who are the beneficial owners of the temporary Global Security with
respect to which such certification was made will be exchanged for definitive
Securities of the same series and of like tenor on the Exchange Date or the date
of certification if such date occurs after the Exchange Date, without further
act or deed by such beneficial owners. Except as otherwise provided in this
paragraph, no payments of principal or interest owing with respect to a
beneficial interest in a temporary Global Security will be made unless and until
such interest in such temporary Global Security shall have been exchanged for an
interest in a definitive Security. Any interest so received by Euroclear and
CEDEL and not paid as herein provided shall be returned to the Trustee prior to
the expiration of two years after such Interest Payment Date in order to be
repaid to the Company.

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

      Subject to the provisions of this Section 305, upon surrender for
registration of transfer of any Registered Security of any series at any office
or agency of the Company in a Place of Payment for that series, the Company
shall execute, and the Trustee shall authenticate and deliver, in the name of
the designated transferee or transferees, one or more new Registered

                                       28
<PAGE>
Securities of the same series, of any authorized denominations and of a like
aggregate principal amount, bearing a number not contemporaneously outstanding,
and containing identical terms and provisions.

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

      If (but only if) permitted by the applicable Board Resolution and (subject
to Section 303) set forth in the applicable Officers' Certificate, or in any
indenture supplemental hereto, delivered as contemplated by Section 301, at the
option of the Holder, Bearer Securities of any series may be exchanged for
Registered Securities of the same series of any authorized denominations and of
a like aggregate principal amount and tenor, upon surrender of the Bearer
Securities to be exchanged at any such office or agency, with all unmatured
coupons and all matured coupons in default thereto appertaining. If the Holder
of a Bearer Security is unable to produce any such unmatured coupon or coupons
or matured coupon or coupons in default, any such permitted exchange may be
effected if the Bearer Securities are accompanied by payment in funds acceptable
to the Company in an amount equal to the face amount of such missing coupon or
coupons, or the surrender of such missing coupon or coupons may be waived by the
Company and the Trustee if there is furnished to them such security or indemnity
as they may require to save each of them and any Paying Agent harmless. If
thereafter the Holder of such Security shall surrender to any Paying Agent any
such missing coupon in respect of which such a payment shall have been made,
such Holder shall be entitled to receive the amount of such payment; provided,
however, that, except as otherwise provided in Section 1002, interest
represented by coupons shall be payable only upon presentation and surrender of
those coupons at an office or agency located outside the United States.
Notwithstanding the foregoing, in case a Bearer Security of any series is
surrendered at any such office or agency in a permitted exchange for a
Registered Security of the same series and like tenor after the close of
business at such office or agency on (i) any Regular Record Date and before the
opening of business at such office or agency on the relevant Interest Payment
Date, or (ii) any Special Record Date and before the opening of business at such
office or agency on the related proposed date for payment of Defaulted Interest,
such Bearer Security shall be surrendered without the coupon relating to such
Interest Payment Date or proposed date for payment, as the case may be, and
interest or Defaulted Interest, as the case may be, will not be payable on such
Interest Payment Date or proposed date for payment, as the case may be, in
respect of the Registered Security issued in exchange for such Bearer Security,
but will be payable only to the Holder of such coupon when due in

                                       29
<PAGE>
accordance with the provisions of this Indenture. Whenever any Securities are so
surrendered for exchange, the Company shall execute, and the Trustee shall
authenticate and deliver, the Securities which the Holder making the exchange is
entitled to receive.

      Notwithstanding the foregoing, except as otherwise specified as
contemplated by Section 301, any permanent Global Security shall be exchangeable
only as provided in this paragraph. If the depository for any permanent Global
Security is The Depository Trust Company ("DTC"), then, unless the terms of such
Global Security expressly permit such Global Security to be exchanged in whole
or in part for definitive Securities, a Global Security may be transferred, in
whole but not in part, only to a nominee of DTC, or by a nominee of DTC to DTC,
or to a successor to DTC for such Global Security selected or approved by the
Company or to a nominee of such successor to DTC. If at any time DTC notifies
the Company that it is unwilling or unable to continue as depository for the
applicable Global Security or Securities or if at any time DTC ceases to be a
clearing agency registered under the Securities Exchange Act of 1934 if so
required by applicable law or regulation, the Company shall appoint a successor
depository with respect to such Global Security or Securities. If (x) a
successor depository for such Global Security or Securities is not appointed by
the Company within 90 days after the Company receives such notice or becomes
aware of such unwillingness, inability or ineligibility, (y) an Event of Default
has occurred and is continuing and the beneficial owners representing a majority
in principal amount of the applicable series of Securities represented by such
Global Security or Securities advise DTC to cease acting as depository for such
Global Security or Securities or (z) the Company, in its sole discretion,
determines at any time that all Outstanding Securities (but not less than all)
of any series issued or issuable in the form of one or more Global Securities
shall no longer be represented by such Global Security or Securities, then the
Company shall execute, and the Trustee shall authenticate and deliver definitive
Securities of like series, rank, tenor and terms in definitive form in an
aggregate principal amount equal to the principal amount of such Global Security
or Securities. If any beneficial owner of an interest in a permanent global
Security is otherwise entitled to exchange such interest for Securities of such
series and of like tenor and principal amount of another authorized form and
denomination, as specified as contemplated by Section 301 and provided that any
applicable notice provided in the permanent Global Security shall have been
given, then without unnecessary delay but in any event not later than the
earliest date on which such interest may be so exchanged, the Company shall
execute, and the Trustee shall authenticate and deliver definitive Securities in
aggregate principal amount equal to the principal amount of such beneficial
owner's interest in such permanent Global Security. On or after the earliest
date on which such interests may be so exchanged, such permanent Global Security
shall be surrendered for exchange by DTC or such other depository as shall be
specified in the Company Order with respect thereto to the Trustee, as the
Company's agent for such purpose; provided, however, that no such exchanges may
occur during a period beginning at the opening of business 15 days before any
selection of Securities to be redeemed and ending on the relevant Redemption
Date if the Security for which exchange is requested may be among those selected
for redemption; and provided further that no Bearer Security delivered in
exchange for a portion of a permanent Global Security shall be mailed or

                                       30
<PAGE>
otherwise delivered to any location in the United States. If a Registered
Security is issued in exchange for any portion of a permanent Global Security
after the close of business at the office or agency where such exchange occurs
on (i) any Regular Record Date and before the opening of business at such office
or agency on the relevant Interest Payment Date, or (ii) any Special Record Date
and the opening of business at such office or agency on the related proposed
date for payment of Defaulted Interest, interest or Defaulted Interest, as the
case may be, will not be payable on such Interest Payment Date or proposed date
for payment, as the case may be, in respect of such Registered Security, but
will be payable on such Interest Payment Date or proposed date for payment, as
the case may be, only to the Person to whom interest in respect of such portion
of such permanent Global Security is payable in accordance with the provisions
of this Indenture.

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

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

      No service charge shall be made for any registration of transfer or
exchange of Securities, but the Company may require payment of a sum sufficient
to cover any tax or other governmental charge that may be imposed in connection
with any registration of transfer or exchange of Securities, other than
exchanges pursuant to Section 304, 906, 1107 or 1305 not involving any transfer.

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

                                       31
<PAGE>
exchange any Security which has been surrendered for repayment at the option of
the Holder, except the portion, if any, of such Security not to be so repaid.

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

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

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

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

                                       32
<PAGE>
      Every new Security of any series with its coupons, if any, issued pursuant
to this Section in lieu of any destroyed, lost or stolen Security, or in
exchange for a Security to which a destroyed, lost or stolen coupon appertains,
shall constitute an original additional contractual obligation of the Company,
whether or not the destroyed, lost or stolen Security and its coupons, if any,
or the destroyed, lost or stolen coupon shall be at any time enforceable by
anyone, and shall be entitled to all the benefits of this Indenture equally and
proportionately with any and all other Securities of that series and their
coupons, if any, duly issued hereunder.

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

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

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

      Unless otherwise provided as contemplated by Section 301, every permanent
global Security will provide that interest, if any, payable on any Interest
Payment Date will be paid to DTC, Euroclear and/or CEDEL, as the case may be,
with respect to that portion of such permanent global Security held for its
account by Cede & Co. or the Common Depository, as the case may be, for the
purpose of permitting such party to credit the interest received by it in
respect of such permanent global Security to the accounts of the beneficial
owners thereof.

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

                                       33
<PAGE>
      Except as otherwise specified with respect to a series of Securities in
accordance with the provisions of Section 301, any interest on any Registered
Security of any series that is payable, but is not punctually paid or duly
provided for, on any Interest Payment Date (herein called "Defaulted Interest")
shall forthwith cease to be payable to the registered Holder thereof on the
relevant Regular Record Date by virtue of having been such Holder, and such
Defaulted Interest may be paid by the Company, at its election in each case, as
provided in clause (1) or (2) below:

                  (1) The Company may elect to make payment of any Defaulted
      Interest to the Persons in whose names the Registered Securities of such
      series (or their respective Predecessor Securities) are registered at the
      close of business on a Special Record Date for the payment of such
      Defaulted Interest, which shall be fixed in the following manner. The
      Company shall notify the Trustee in writing of the amount of Defaulted
      Interest proposed to be paid on each Registered Security of such series
      and the date of the proposed payment (which shall not be less than 20 days
      after such notice is received by the Trustee), and at the same time the
      Company shall deposit with the Trustee an amount of money in the currency
      or currencies, currency unit or units or composite currency or currencies
      in which the Securities of such series are payable (except as otherwise
      specified pursuant to Section 301 for the Securities of such series) equal
      to the aggregate amount proposed to be paid in respect of such Defaulted
      Interest or shall make arrangements satisfactory to the Trustee for such
      deposit on or prior to the date of the proposed payment, such money when
      deposited to be held in trust for the benefit of the Persons entitled to
      such Defaulted Interest as in this clause provided. Thereupon the Trustee
      shall fix a Special Record Date for the payment of such Defaulted Interest
      which shall be not more than 15 days and not less than 10 days prior to
      the date of the proposed payment and not less than 10 days after the
      receipt by the Trustee of the notice of the proposed payment. The Trustee
      shall promptly notify the Company of such Special Record Date and, in the
      name and at the expense of the Company, shall cause notice of the proposed
      payment of such Defaulted Interest and the Special Record Date therefor to
      be mailed, first-class postage prepaid, to each Holder of Registered
      Securities of such series at his address as it appears in the Security
      Register not less than 10 days prior to such Special Record Date. The
      Trustee may, in its discretion, in the name and at the expense of the
      Company, cause a similar notice to be published at least once in an
      Authorized Newspaper in each Place of Payment, but such publications shall
      not be a condition precedent to the establishment of such Special Record
      Date. Notice of the proposed payment of such Defaulted Interest and the
      Special Record Date therefor having been mailed as aforesaid, such
      Defaulted Interest shall be paid to the Persons in whose names the
      Registered Securities of such series (or their respective Predecessor
      Securities) are registered at the close of business on such Special Record
      Date and shall no longer be payable pursuant to the following clause (2).
      In case a Bearer Security of any series is surrendered at the office or
      agency in a Place of Payment for such series in exchange for a Registered
      Security of such series after the close of business at such office or
      agency on any Special Record Date and

                                       34
<PAGE>
      before the opening of business at such office or agency on the related
      proposed date for payment of Defaulted Interest, such Bearer Security
      shall be surrendered without the coupon relating to such proposed date of
      payment and Defaulted Interest will not be payable on such proposed date
      of payment in respect of the Registered Security issued in exchange for
      such Bearer Security, but will be payable only to the Holder of such
      coupon when due in accordance with the provisions of this Indenture.

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

      Subject to the foregoing provisions of this Section and Section 305, each
Security delivered under this Indenture upon registration of transfer of or in
exchange for or in lieu of any other Security shall carry the rights to interest
accrued and unpaid, and to accrue, which were carried by such other Security.

      SECTION 308. Persons Deemed Owners. Prior to due presentment of a
Registered Security for registration of transfer, the Company, the Trustee and
any agent of the Company or the Trustee may treat the Person in whose name such
Registered Security is registered as the owner of such Security for the purpose
of receiving payment of principal of (and premium or Make-Whole Amount, if any),
and (subject to Sections 305 and 307) interest on, such Registered Security and
for all other purposes whatsoever, whether or not such Registered Security be
overdue, and neither the Company, the Trustee nor any agent of the Company or
the Trustee shall be affected by notice to the contrary. All such payments so
made to any such Person, or upon such Person's order, shall be valid, and, to
the extent of the sum or sums so paid, effectual to satisfy and discharge the
liability for money payable upon any such Security.

      Title to any Bearer Security and any coupons appertaining thereto shall
pass by delivery. The Company, the Trustee and any agent of the Company or the
Trustee may treat the Holder of any Bearer Security and the Holder of any coupon
as the absolute owner of such Security or coupon for the purpose of receiving
payment thereof or on account thereof and for all other purposes whatsoever,
whether or not such Security or coupon be overdue, and neither the Company, the
Trustee nor any agent of the Company or the Trustee shall be affected by notice
to the contrary.

      No holder of any beneficial interest in any Global Security held on its
behalf by a depository shall have any rights under this Indenture with respect
to such Global Security and such depository (which is the Holder of such
security) shall be treated by the Company, the Trustee, and any agent of the
Company or the Trustee as the owner of such Global Security for all purposes
whatsoever. None of the Company, the Trustee, any Paying Agent or the

                                       35
<PAGE>
Security Registrar will have any responsibility or liability for any aspect of
the records relating to or payments made on account of beneficial ownership
interests of a Global Security or for maintaining, supervising or reviewing any
records relating to such beneficial ownership interests.

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

      SECTION 309. Cancellation. All Securities and coupons surrendered for
payment, redemption, repayment at the option of the Holder, registration of
transfer or exchange or for credit against any sinking fund payment shall, if
surrendered to any Person other than the Trustee, be delivered to the Trustee,
and any such Securities and coupons and Securities and coupons surrendered
directly to the Trustee for any such purpose shall be promptly cancelled by it.
The Company may at any time deliver to the Trustee for cancellation any
Securities previously authenticated and delivered hereunder which the Company
may have acquired in any manner whatsoever, and 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 cancelled by the Trustee. If
the Company shall so acquire any of the Securities, however, such acquisition
shall not operate as a redemption or satisfaction of the indebtedness
represented by such Securities unless and until the same are surrendered to the
Trustee for cancellation. No Securities shall be authenticated in lieu of or in
exchange for any Securities cancelled as provided in this Section, except as
expressly permitted by this Indenture. Cancelled Securities and coupons held by
the Trustee shall be destroyed by the Trustee and the Trustee shall deliver a
certificate of such destruction to the Company, unless the Trustee is otherwise
directed by a Company Order.

      SECTION 310. Computation of Interest. Except as otherwise specified as
contemplated by Section 301 with respect to Securities of any series, interest
on the Securities of each series shall be computed on the basis of a 360-day
year consisting of twelve 30-day months.

                    ARTICLE FOUR - SATISFACTION AND DISCHARGE

      SECTION 401. Satisfaction and Discharge of Indenture. This Indenture shall
upon Company Request cease to be of further effect with respect to any series of
Securities specified in such Company Request (except as to any surviving rights
of registration of transfer or

                                       36
<PAGE>
exchange of Securities of such series herein expressly provided for), and the
Trustee, upon receipt of a Company Order, and at the expense of the Company,
shall execute instruments in form and substance satisfactory to the Trustee and
the Company acknowledging satisfaction and discharge of this Indenture as to
such series when

                  (1) either

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

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

                        (i) have become due and payable, or

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

                        (iii) if redeemable at the option of the Company, are to
                  be called for redemption within one year under arrangements
                  satisfactory to the Trustee for the giving of notice of
                  redemption by the Trustee in the name, and at the expense, of
                  the Company,

            and the Company, in the case of (i), (ii) or (iii) above, has
            irrevocably deposited or caused to be deposited with the Trustee as
            trust funds in trust for the purpose an amount in the currency or
            currencies, currency unit or units or composite currency or
            currencies in which the Securities of such series are payable,
            sufficient to pay and discharge the entire indebtedness on such
            Securities and such coupons not theretofore delivered to the Trustee
            for cancellation, for principal (and premium or Make-Whole Amount,
            if any) and interest to the date

                                       37
<PAGE>
            of such deposit (in the case of Securities which have become due and
            payable) or to the Stated Maturity or Redemption Date, as the case
            may be;

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

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

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

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

                             ARTICLE FIVE - REMEDIES

      SECTION 501. Events of Default. "Event of Default," wherever used herein
with respect to any particular series of Securities, means any one of the
following events (whatever the reason for such Event of Default and whether or
not it shall be voluntary or involuntary or be effected by operation of law or
pursuant to any judgment, decree or order of any court or any order, rule or
regulation of any administrative or governmental body):

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

                                       38
<PAGE>
                  (2) default in the payment of the principal of (or premium or
      Make-Whole Amount, if any, on) any Security of that series when it becomes
      due and payable at its Maturity; or

                  (3) default in the deposit of any sinking fund payment, when
      and as due by the terms of any Security of that series; or

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

                  (5) default under any bond, debenture, note, mortgage,
      indenture or instrument under which there may be issued or by which there
      may be secured or evidenced any indebtedness for money borrowed by the
      Company (or by any Subsidiary, the repayment of which the Company has
      guaranteed or for which the Company is directly responsible or liable as
      obligor or guarantor), having an aggregate principal amount outstanding of
      at least $25,000,000, whether such indebtedness now exists or shall
      hereafter be created, which default shall have resulted in such
      indebtedness becoming or being declared due and payable prior to the date
      on which it would otherwise have become due and payable, without such
      indebtedness having been discharged, or such acceleration having been
      rescinded or annulled, within a period of 10 days after there shall have
      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 10% in
      principal amount of the Outstanding Securities of that series a written
      notice specifying such default and requiring the Company to cause such
      indebtedness to be discharged or cause such acceleration to be rescinded
      or annulled and stating that such notice is a "Notice of Default"
      hereunder; or

                  (6) the Company or any Significant Subsidiary pursuant to or
      within the meaning of any Bankruptcy Law:

                        (A) commences a voluntary case,

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

                                       39
<PAGE>
                        (C) consents to the appointment of a Custodian of it or
            for all or substantially all of its property, or

                        (D) makes a general assignment for the benefit of its
            creditors; or

                  (7) a court of competent jurisdiction enters an order or
      decree under any Bankruptcy Law that:

                        (A) is for relief against the Company or any Significant
            Subsidiary in an involuntary case,

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

                        (C) orders the liquidation of the Company or any
            Significant Subsidiary, and the order or decree remains unstayed and
            in effect for 90 days; or

                  (8) any other Event of Default provided with respect to
      Securities of that series.

As used in this Section 501, the term "Bankruptcy Law" means title 11, U.S. Code
or any similar Federal or state law for the relief of debtors and the term
"Custodian" means any receiver, trustee, assignee, liquidator or other similar
official under any Bankruptcy Law.

      SECTION 502. Acceleration of Maturity; Rescission and Annulment. If an
Event of Default with respect to Securities of any series at the time
Outstanding occurs and is continuing, then and in every such case the Trustee or
the Holders of not less than 25% in principal amount of the Outstanding
Securities of that series may declare the principal amount (or, if Securities of
that Series are Original Issue Discount Securities or Indexed Securities, such
portion of the principal as may be specified in the terms thereof) of all the
Securities of that series to be due and payable immediately, by a notice in
writing to the Company (and to the Trustee if given by the Holders), and upon
any such declaration such principal or specified portion thereof shall become
immediately due and payable.

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

                                       40
<PAGE>
                  (1) the Company has paid or deposited with the Trustee a sum
      sufficient to pay in the currency, currency unit or composite currency in
      which the Securities of such series are payable (except as otherwise
      specified pursuant to Section 301 for the Securities of such series):

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

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

                        (C) to the extent that payment of such interest is
            lawful, interest upon overdue installments of interest at the rate
            or rates borne by or provided for in such Securities, and

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

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

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

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

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

                  (2) default is made in the payment of the principal of (or
      premium or Make-Whole Amount, if any, on) any Security of any series at
      its Maturity,

then the Company will, upon demand of the Trustee, pay to the Trustee, for the
benefit of the Holders of such Securities of such series and coupons, the whole
amount then due and payable on such Securities and coupons for principal (and
premium or Make-Whole Amount, if any) and interest, with interest upon any
overdue principal (and premium or Make-Whole Amount, if any) and, to the extent
that payment of such interest shall be legally enforceable, upon any

                                       41
<PAGE>
overdue installments of interest at the rate or rates borne by or provided for
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.

      If the Company fails to pay such amounts forthwith upon such demand, the
Trustee, in its own name and as trustee of an express trust, may institute a
judicial proceeding for the collection of the sums so due and unpaid, and may
prosecute such proceeding to judgment or final decree, and may enforce the same
against the Company or any other obligor upon such Securities of such series and
collect the moneys adjudged or decreed to be payable in the manner provided by
law out of the property of the Company or any other obligor upon such Securities
of such series, wherever situated.

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

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

                        (i) to file and prove a claim for the whole amount, or
      such lesser amount as may be provided for in the Securities of such
      series, of principal (and premium or Make-Whole Amount, if any) and
      interest owing and unpaid in respect of the Securities and to file such
      other papers or documents as may be necessary or advisable in order to
      have the claims of the Trustee (including any claim for the reasonable
      compensation, expenses, disbursements and advances of the Trustee, its
      agents and counsel) and of the Holders allowed in such judicial
      proceeding, and

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

and any custodian, receiver, assignee, trustee, liquidator, sequestrator (or
other similar official) in any such judicial proceeding is hereby authorized by
each Holder of Securities of

                                       42
<PAGE>
such series and coupons to make such payments to the Trustee, and in the event
that the Trustee shall consent to the making of such payments directly to the
Holders, to pay to the Trustee any amount due to it for the reasonable
compensation, expenses, disbursements and advances of the Trustee and any
predecessor Trustee, their agents and counsel, and any other amounts due the
Trustee or any predecessor Trustee under Section 606.

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

      In any proceedings brought by the Trustee (and also any proceedings
involving the interpretation of any provision of this Indenture to which the
Trustee shall be a party) the Trustee shall be held to represent all the Holders
of the Securities, and it shall not be necessary to make any Holders of the
Securities parties to any such proceedings.

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

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

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

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

                                       43
<PAGE>
            THIRD: To the payment of the remainder, if any, to the Company.

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

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

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

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

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

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

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

      SECTION 508. Unconditional Right of Holders to Receive Principal, Premium
or Make-Whole Amount, if any, and Interest. Notwithstanding any other provision
in this Indenture, the Holder of any Security or coupon shall have the right
which is absolute and unconditional to receive payment of the principal of (and
premium or Make-Whole Amount, if any) and (subject to Sections 305 and 307)
interest on such Security or payment of such coupon on the respective due dates
expressed in such Security or coupon (or, in the case of redemption, on the
Redemption Date) and to institute suit for the enforcement of any such payment,
and such rights shall not be impaired without the consent of such Holder.

                                       44
<PAGE>
      SECTION 509. Restoration of Rights and Remedies. If the Trustee or any
Holder of a Security or coupon has instituted any proceeding to enforce any
right or remedy under this Indenture and such proceeding has been discontinued
or abandoned for any reason, or has been determined adversely to the Trustee or
to such Holder, then and in every such case, the Company, the Trustee and the
Holders of Securities and coupons shall, subject to any determination in such
proceeding, be restored severally and respectively to their former positions
hereunder and thereafter all rights and remedies of the Trustee and the Holders
shall continue as though no such proceeding had been instituted.

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

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

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

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

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

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

                                       45
<PAGE>
      Nothing in this Indenture shall impair the right of the Trustee in its
discretion to take any action deemed proper by the Trustee and which is not
inconsistent with such direction by Holders.

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

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

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

                  (3) in respect of a covenant or provision hereof for the
      benefit or protection of the Trustee, without its express written consent.

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

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

      SECTION 515. Undertaking for Costs. All parties to this Indenture agree,
and each Holder of any Security by his acceptance thereof shall be deemed to
have agreed, that any court may in its discretion require, in any suit for the
enforcement of any right or remedy under this Indenture, or in any suit against
the Trustee for any action taken or omitted by it as Trustee, the filing by any
party litigant in such suit of an undertaking to pay the costs of such suit, and
that such court may in its discretion assess reasonable costs, including
reasonable attorneys' fees, against any party litigant in such suit having due
regard to the merits and good faith of the claims or defenses made by such party
litigant; but the provisions of this Section shall not apply to any suit
instituted by the Trustee, to any suit instituted by any Holder, or group of
Holders, holding in the aggregate more than 10% in principal amount of the

                                       46
<PAGE>
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 or Make-Whole
Amount, if any) or interest on any Security on or after the respective Stated
Maturities expressed in such Security (or, in the case of redemption, on or
after the Redemption Date).

                            ARTICLE SIX - THE TRUSTEE

      SECTION 601. Notice of Defaults. Within 90 days after the occurrence of
any default hereunder with respect to the Securities of any series, the Trustee
shall transmit in the manner and to the extent provided in TIA Section 313(c),
notice of such default hereunder known to the Trustee, unless such default shall
have been cured or waived; provided, however, that, except in the case of a
default in the payment of the principal of (or premium or Make-Whole Amount, if
any) or interest on any Security of such series, or in the payment of any
sinking or purchase fund installment with respect to the Securities of such
series, the Trustee shall be protected in withholding such notice if and so long
as the board of directors, the executive committee, or a trust committee of
directors and/or Responsible Officers of the Trustee in good faith determine
that the withholding of such notice is in the interests of the Holders of the
Securities and coupons of such series; and provided further that in the case of
any default or breach of the character specified in Section 501(4) with respect
to the Securities and coupons of such series, no such notice to Holders shall be
given until at least 60 days after the occurrence thereof. For the purpose of
this Section, the term "default" means any event which is, or after notice or
lapse of time or both would become, an Event of Default with respect to the
Securities of such series.

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

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

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

                  (3) whenever in the administration of this Indenture the
      Trustee shall deem it desirable that a matter be proved or established
      prior to taking, suffering or

                                       47
<PAGE>
      omitting any action hereunder, the Trustee (unless other evidence be
      herein specifically prescribed) may, in the absence of bad faith on its
      part, rely upon an Officers' Certificate;

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

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

                  (6) the Trustee shall not be bound to make any investigation
      into the facts or matters stated in any resolution, certificate,
      statement, instrument, opinion, report, notice, request, direction,
      consent, order, bond, debenture, note, coupon or other paper or document,
      unless requested in writing so to do by the Holders of not less than a
      majority in aggregate principal amount of the Outstanding Securities of
      any series; provided that, if the payment within a reasonable time to the
      Trustee of the costs, expenses or liabilities likely to be incurred by it
      in the making of such investigation is, in the opinion of the Trustee, not
      reasonably assured to the Trustee by the security afforded to it by the
      terms of this Indenture, the Trustee may require reasonable indemnity
      against such expenses or liabilities as a condition to proceeding; the
      reasonable expenses of every such examination shall be paid by the Holders
      or, if paid by the Trustee, shall be repaid by the Holders upon demand.
      The Trustee, in its discretion, may make such further inquiry or
      investigation into such facts or matters as it may see fit, and, if the
      Trustee shall determine to make such further inquiry or investigation, it
      shall be entitled to examine the books, records and premises of the
      Company, relevant to the facts or matters that are the subject of its
      inquiry, personally or by agent or attorney;

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

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

                                       48
<PAGE>
                  (9) any permissive right or power available to the Trustee
      under this Indenture or any supplement hereto shall not be construed to be
      a mandatory duty or obligation;

                  (10) the Trustee shall not be charged with knowledge of any
      matter (including any default, other than as described in Section 501(1),
      (2) or (3)) unless and except to the extent actually known to a
      Responsible Officer of the Trustee or to the extent written notice thereof
      is received by the Trustee at the Corporate Trust Office; and

                  (11) the Trustee shall have no liability for the selection of
      any Independent Investment Banker; and shall have no liability for any
      inaccuracy in the books and records of, or for any actions or omissions
      of, DTC, Euroclear or CEDEL or any depository acting on behalf of any of
      them.

      The Trustee shall not be required to expend or risk its own funds or
otherwise incur any financial liability in the performance of any of its duties
hereunder, or in the exercise of any of its rights or powers, if it shall have
reasonable grounds for believing that repayment of such funds or adequate
indemnity against such risk or liability is not reasonably assured to it.

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

      SECTION 603. Not Responsible for Recitals or Issuance of Securities. The
recitals contained herein and in the Securities, except the Trustee's
certificate of authentication, and in any coupons shall be taken as the
statements of the Company, and neither the Trustee nor any Authenticating Agent
assumes any responsibility for their correctness. The Trustee makes no
representations as to the validity or sufficiency of this Indenture or of the
Securities or coupons, except that the Trustee represents that it is duly
authorized to execute and deliver this Indenture, authenticate the Securities
and perform its obligations hereunder. Neither the Trustee nor any
Authenticating Agent shall be accountable for the use or application by the
Company of Securities or the proceeds thereof.

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

      SECTION 605. Money Held in Trust. Money held by the Trustee in trust
hereunder need not be segregated from other funds except to the extent required
by law. The Trustee

                                       49
<PAGE>
shall be under no liability for interest on any money received by it hereunder
except as otherwise agreed with the Company.

      SECTION 606. Compensation and Reimbursement. The Company agrees:

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

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

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

      When the Trustee incurs expenses or renders services in connection with an
Event of Default specified in Section 501(7) or Section 501(8), the expenses
(including the reasonable charges and expenses of its counsel) and the
compensation for the services are intended to constitute expenses of
administration under any applicable Federal or state bankruptcy, insolvency or
other similar law.

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

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

      SECTION 607. Corporate Trustee Required; Eligibility; Conflicting
Interests. There shall at all times be a Trustee hereunder which shall be
eligible to act as Trustee under TIA Section 310(a)(1) and shall have at all
times a combined capital and surplus of at least $50,000,000. If the Trustee
publishes reports of condition at least annually, pursuant to law or the
requirements of Federal, state, territorial or District of Columbia supervising
or examining authority, then for the purposes of this Section, the combined
capital and surplus of the Trustee shall be deemed to be its combined capital
and surplus as set forth in its most recent report of

                                       50
<PAGE>
condition so published. If at any time the Trustee shall cease to be eligible in
accordance with the provisions of this Section, it shall resign immediately in
the manner and with the effect hereinafter specified in this Article. Neither
the Company nor any Person directly or indirectly controlling, controlled by, or
under common control with the Company shall serve as Trustee.

      SECTION 608. Resignation and Removal; Appointment of Successor.

            (a) No resignation or removal of the Trustee and no appointment of a
successor Trustee pursuant to this Article shall become effective until the
acceptance of appointment by the successor Trustee in accordance with the
applicable requirements of Section 609.

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

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

            (d) If at any time:

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

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

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

then, in any such case, (i) the Company by or pursuant to a Board Resolution may
remove the Trustee and appoint a successor Trustee with respect to all
Securities, or (ii) subject to TIA Section 315(e), any Holder of a Security who
has been a bona fide Holder of a Security for at least six months may, on behalf
of himself and all others similarly situated, petition any court of competent
jurisdiction for the removal of the Trustee with respect to all Securities and
the appointment of a successor Trustee or Trustees.

                                       51
<PAGE>
            (e) If the Trustee shall resign, be removed or become incapable of
acting, or if a vacancy shall occur in the office of Trustee for any cause with
respect to the Securities of one or more series, the Company, by or pursuant to
a Board Resolution, shall promptly appoint a successor Trustee or Trustees with
respect to the Securities of that or those series (it being understood that any
such successor Trustee may be appointed with respect to the Securities of one or
more or all of such series and that at any time there shall be only one Trustee
with respect to the Securities of any particular series). If, within one year
after such resignation, removal or incapability, or the occurrence of such
vacancy, a successor Trustee with respect to the Securities of any series shall
be appointed by Act of the Holders of a majority in principal amount of the
Outstanding Securities of such series delivered to the Company and the retiring
Trustee, the successor Trustee so appointed shall, forthwith upon its acceptance
of such appointment, become the successor Trustee with respect to the Securities
of such series and to that extent supersede the successor Trustee appointed by
the Company. If no successor Trustee with respect to the Securities of any
series shall have been so appointed by the Company or the Holders of Securities
and accepted appointment in the manner hereinafter provided, any Holder of a
Security 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 Securities of such series.

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

      SECTION 609. Acceptance of Appointment by Successor. (a) In case of the
appointment hereunder of a successor Trustee with respect to all Securities,
every such successor Trustee 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 request of the Company or the successor
Trustee, such retiring Trustee shall, upon payment of its charges, execute and
deliver an instrument transferring to such successor Trustee all the rights,
powers and trusts of the retiring Trustee, and shall duly assign, transfer and
deliver to such successor Trustee all property and money held by such retiring
Trustee hereunder, subject nevertheless to its claim, if any, provided for in
Section 606.

            (b) In case of the appointment hereunder of a successor Trustee with
respect to the Securities of one or more (but not all) series, the Company, the
retiring Trustee and each successor Trustee with respect to the Securities of
one or more series shall execute and deliver

                                       52
<PAGE>
an indenture supplemental hereto, pursuant to Article Nine hereof, wherein each
successor Trustee shall accept such appointment and which (1) shall contain such
provisions as shall be necessary or desirable to transfer and confirm to, and to
vest in, each successor Trustee all the rights, powers, trusts and duties of the
retiring Trustee with respect to the Securities of that or those series to which
the appointment of such successor Trustee relates, (2) if the retiring Trustee
is not retiring with respect to all Securities, shall contain such provisions as
shall be deemed necessary or desirable to confirm that all the rights, powers,
trusts and duties of the retiring Trustee with respect to the Securities of that
or those series as to which the retiring Trustee is not retiring shall continue
to be vested in the retiring Trustee, and (3) shall add to or change any of the
provisions of this Indenture as shall be necessary to provide for or facilitate
the administration of the trusts hereunder by more than one Trustee, it being
understood that nothing herein or in such supplemental indenture shall
constitute such Trustees co-trustees of the same trust and that each such
Trustee shall be trustee of a trust or trusts hereunder separate and apart from
any trust or trusts hereunder administered by any other such Trustee; and upon
the execution and delivery of such supplemental indenture the resignation or
removal of the retiring Trustee shall become effective to the extent provided
therein and each such successor Trustee, without any further act, deed or
conveyance, shall become vested with all the rights, powers, trusts and duties
of the retiring Trustee with respect to the Securities of that or those series
to which the appointment of such successor Trustee relates; but, on request of
the Company or any successor Trustee, such retiring Trustee shall duly assign,
transfer and deliver to such successor Trustee all property and money held by
such retiring Trustee hereunder with respect to the Securities of that or those
series to which the appointment of such successor Trustee relates.

            (c) Upon request of any such successor Trustee, the Company shall
execute any and all instruments for more fully and certainly vesting in and
confirming to such successor Trustee all such rights, powers and trusts referred
to in paragraph (a) or (b) of this Section 609, as the case may be.

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

      SECTION 610. Merger, Conversion, Consolidation or Succession to Business.
Any corporation into which the Trustee may be merged or converted or with which
it may be consolidated, or any corporation resulting from any merger, conversion
or consolidation to which the Trustee shall be a party, or any corporation
succeeding to all or substantially all of the corporate trust business of the
Trustee, shall be the successor of the Trustee hereunder, provided such
corporation shall be otherwise qualified and eligible under this Article,
without the execution or filing of any paper or any further act on the part of
any of the parties hereto. In case any Securities or coupons shall have been
authenticated, but not delivered, by the Trustee then in office, any successor
by merger, conversion or consolidation to such authenticating Trustee may adopt
such authentication and deliver the Securities or coupons so authenticated with
the same effect as if such successor Trustee had itself authenticated such

                                       53
<PAGE>
Securities or coupons. In case any Securities or coupons shall not have been
authenticated by such predecessor Trustee, any such successor Trustee may
authenticate and deliver such Securities or coupons, in either its own name or
that of its predecessor Trustee, with the full force and effect which this
Indenture provides for the certificate of authentication of the Trustee.

      SECTION 611. Appointment of Authenticating Agent. At any time when any of
the Securities remain Outstanding, the Trustee may appoint an Authenticating
Agent or Agents with respect to one or more series of Securities which shall be
authorized to act on behalf of the Trustee to authenticate Securities of such
series issued upon exchange, registration of transfer or partial redemption or
repayment thereof, and Securities so authenticated shall be entitled to the
benefits of this Indenture and shall be valid and obligatory for all purposes as
if authenticated by the Trustee hereunder. Any such appointment shall be
evidenced by an instrument in writing signed by a Responsible Officer of the
Trustee, a copy of which instrument shall be promptly furnished to the Company.
Wherever reference is made in this Indenture to the authentication and delivery
of Securities by the Trustee or the Trustee's certificate of authentication,
such reference shall be deemed to include authentication and delivery on behalf
of the Trustee by an Authenticating Agent and a certificate of authentication
executed on behalf of the Trustee by an Authenticating Agent. Each
Authenticating Agent shall be acceptable to the Company and shall at all times
be a bank or trust company or corporation organized and doing business and in
good standing under the laws of the United States of America or of any state or
the District of Columbia, authorized under such laws to act as Authenticating
Agent, having a combined capital and surplus of not less than $50,000,000 and
subject to supervision or examination by Federal or state authorities. If such
Authenticating Agent publishes reports of condition at least annually, pursuant
to law or the requirements of the aforesaid supervising or examining authority,
then for the purposes of this Section, the combined capital and surplus of such
Authenticating Agent shall be deemed to be its combined capital and surplus as
set forth in its most recent report of condition so published. In case at any
time an Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, such Authenticating Agent shall resign immediately
in the manner and with the effect specified in this Section.

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

      An Authenticating Agent for any series of Securities may at any time
resign by giving written notice of resignation to the Trustee for such series
and to the Company. The Trustee for any series of Securities may at any time
terminate the agency of an Authenticating Agent by

                                       54
<PAGE>
giving written notice of termination 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 for such series may
appoint a successor Authenticating Agent which shall be acceptable to the
Company and shall give notice of such appointment to all Holders of Securities
of the series with respect to which such Authenticating Agent will serve in the
manner set forth in Section 106. Any successor Authenticating Agent upon
acceptance of its appointment hereunder shall become vested with all the rights,
powers and duties of its predecessor hereunder, with like effect as if
originally named as an Authenticating Agent herein. No successor Authenticating
Agent shall be appointed unless eligible under the provisions of this Section.

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

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

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

      SECTION 612. Certain Duties and Responsibilities of the Trustee.

      (a) With respect to the Securities of any series, except during the
continuance of an Event of Default with respect to the Securities of such
series:

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

                                       55
<PAGE>
            (2) 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, but shall not be
      under any duty to verify the contents or accuracy thereof.

      (b) In case an Event of Default with respect to the Securities of any
series has occurred and is continuing, the Trustee shall, with respect to
Securities of such series, 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 man would exercise or use under the circumstances in the conduct of
his own affairs.

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

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

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

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

            (4) no provision of this Indenture shall require the Trustee to
      expend or risk its own funds or otherwise incur any financial liability in
      the performance of any of its duties hereunder, or in the exercise of any
      of its rights or powers, if it shall have reasonable grounds for believing
      that repayment of such funds or adequate indemnity against such risk or
      liability is not reasonably assured to it.

      (d) Whether or not therein expressly so provided, every provision of this
Indenture relating to the conduct or affecting the liability of or affording
protection to the Trustee shall be subject to the provisions of this Section
612.

                                       56
<PAGE>
      (e) The Trustee shall not be liable for interest on any money or assets
held by it except to the extent the Trustee may agree in writing with the
Company. Assets held in trust by the Trustee need not be segregated from other
assets except to the extent required by law.

      SECTION 701. Disclosure of Names and Addresses of Holders. Every Holder of
Securities or coupons, by receiving and holding the same, agrees with the
Company and the Trustee that neither the Company nor the Trustee nor any
Authenticating Agent nor any Paying Agent nor any Security Registrar shall be
held accountable by reason of the disclosure of any information as to the names

semiannually, upon such dates as are set forth in the Board Resolution or
indenture supplemental hereto authorizing such series, and

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

      SECTION 801. Consolidations and Mergers of Company and Sales, Leases and
Conveyances Permitted Subject to Certain Conditions. The Company may consolidate
with, or sell, lease or convey all or substantially all of its assets to, or
merge with or into any other corporation, provided that in any such case, (1)
either the Company shall be the continuing corporation, or the successor
corporation shall be a corporation organized and existing under the laws of the
United States or a State thereof and such successor corporation shall expressly
assume the due and punctual payment of the principal of (and premium or
Make-Whole Amount, if any) and any interest on all of 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, complying with Article Nine hereof, satisfactory to the
Trustee, executed and delivered to the Trustee by such corporation and (2)
immediately after giving effect to such transaction and treating any
indebtedness which becomes an obligation of the Company or any Subsidiary as a
result thereof as having been incurred by the Company or such Subsidiary at the
time of such

                                       58
<PAGE>
transaction, no Event of Default, and no event which, after notice or the lapse
of time, or both, would become an Event of Default, shall have occurred and be
continuing.

      SECTION 802. Rights and Duties of Successor Corporation. In case of any
such consolidation, merger, sale, lease or conveyance 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 predecessor
corporation, except in the event of a lease, shall be relieved of any further
obligation under this Indenture and the Securities. Such successor corporation
thereupon may cause to be signed, and may issue either in its own name or in the
name of the Company, any or all of the Securities issuable hereunder which
theretofore shall not have been signed by the Company and delivered to the
Trustee; and, upon the order of such successor corporation, instead of the
Company, and subject to all the terms, conditions and limitations in this
Indenture prescribed, the Trustee shall authenticate and shall deliver any
Securities which previously shall have been signed and delivered by the officers
of the Company to the Trustee for authentication, and any Securities which such
successor corporation thereafter shall cause to be signed and delivered to the
Trustee for that purpose. All the Securities so issued shall in all respects
have the same legal rank and benefit under this Indenture as the Securities
theretofore or thereafter issued in accordance with the terms of this Indenture
as though all of such Securities had been issued at the date of the execution
hereof.

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

      SECTION 803. Officers' Certificate and Opinion of Counsel. Any
consolidation, merger, sale, lease or conveyance permitted under Section 801 is
also subject to the condition that the Trustee receive an Officers' Certificate
and an Opinion of Counsel to the effect that any such consolidation, merger,
sale, lease or conveyance, and the assumption by any successor corporation,
complies with the provisions of this Article and that all conditions precedent
herein provided for relating to such transaction have been complied with.

                     ARTICLE NINE - SUPPLEMENTAL INDENTURES

      SECTION 901. Supplemental Indentures Without Consent of Holders. Without

                  (2) 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

                  (3) to add any additional Events of Default for the benefit of
      the Holders of all or any series of Securities (and if such Events of
      Default are to be for the benefit of less than all series of Securities,
      stating that such Events of Default are expressly being included solely
      for the benefit of such series); provided, however, that in respect of any
      such additional Events of Default such supplemental indenture may provide
      for a particular period of grace after default (which period may be
      shorter or longer than that allowed in the case of other defaults) or may
      provide for an immediate enforcement upon such default or may limit the
      remedies available to the Trustee upon such default or may limit the right
      of the Holders of a majority in aggregate principal amount of that or
      those series of Securities to which such additional Events of Default
      apply to waive such default; or

                  (4) to add to or change any of the provisions of this
      Indenture to provide that Bearer Securities may be registrable as to

      provided that any such action shall not adversely affect the interests of
      the Holders of Securities of any series or any related coupons in any
      material respect; or

                  (5) to change or eliminate any of the provisions of this
      Indenture, provided that any such change or elimination shall become
      effective only when there is no Security Outstanding of any series created
      prior to the execution of such supplemental indenture which is entitled to
      the benefit of such provision; or

                  (6) to secure the Securities; or

                  (7) to establish the form or terms of Securities of any series
      and any related coupons as permitted or contemplated by Sections 201 and
      301; or

                                       60
<PAGE>
                  (8) 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 or facilitate the
      administration of the trusts hereunder by more than one Trustee; or

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

                  (10) to supplement any of the provisions of this Indenture to
      such extent as shall be necessary to permit or facilitate the defeasance
      and discharge of any series of Securities pursuant to Sections 401, 1402
      and 1403; provided that any such action shall not adversely affect the
      interests of the Holders of Securities of such series and any related
      coupons or any other series of Securities in any material respect.

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

                  (1) change the Stated Maturity of the principal of (or premium
      or Make-Whole Amount, if any, on) or any installment of principal of or
      interest on, any Security; or reduce the principal amount thereof or the
      rate or amount of interest thereon, or any premium or Make-Whole Amount
      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
      502 or the amount thereof provable in bankruptcy pursuant to Section 504,
      or adversely affect any right of repayment at the option of the Holder of
      any Security, or change any Place of Payment where, or the currency or
      currencies, currency unit or units or composite currency or currencies in
      which, any Security or any premium or Make-Whole Amount 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 or repayment at the option of the Holder,
      on or after the Redemption Date or the Repayment Date, as the case may
      be), or

                                       61
<PAGE>
                  (2) reduce the percentage in principal amount of the
      Outstanding Securities of any series, the consent of whose Holders is
      required for any such supplemental indenture, or the consent of whose
      Holders is required for any waiver with respect to such series (or
      compliance with certain provisions of this Indenture or certain defaults
      hereunder and their consequences) provided for in this Indenture, or
      reduce the requirements of Section 1504 for quorum or voting, or

                  (3) modify any of the provisions of this Section, Section 513
      or Section 1009, except to increase the required percentage to effect such
      action 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 902 and Section 1009, or the deletion of this proviso, in
      accordance with the requirements of Sections 609(b) and 901(11).

      It shall not be necessary for any Act of Holders under this Section 902 to
approve the particular form of any proposed supplemental indenture, but it shall
be sufficient if such Act shall approve the substance thereof.

      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.

      SECTION 903. Execution of Supplemental Indentures. In executing, or

protected in relying upon, an Opinion of Counsel stating that the execution of
such supplemental indenture is authorized or permitted by this Indenture. The
Trustee may, but shall not be obligated to, enter into any such supplemental
indenture which affects the Trustee's own rights, duties or immunities under
this Indenture or otherwise.

      SECTION 904. Effect of Supplemental Indentures. Upon the execution of any
supplemental indenture under this Article, this Indenture shall be modified in

thereto shall be bound thereby.

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

                                       62
<PAGE>
      SECTION 906. Reference in Securities to Supplemental Indentures.
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.

                             ARTICLE TEN - COVENANTS

      SECTION 1001. Payment of Principal, Premium or Make-Whole Amount, if any;
and Interest. The Company covenants and agrees for the benefit of the Holders of
each series of Securities that it will duly and punctually pay the principal of
(and premium or Make-Whole Amount, if any) and interest on the Securities of
that series in accordance with the terms of such series of Securities, any
coupons appertaining thereto and this Indenture. Unless otherwise specified as
contemplated by Section 301 with respect to any series of Securities, any
interest due on Bearer Securities on or before Maturity shall be payable only
upon presentation and surrender of the several coupons for such interest
installments as are evidenced thereby as they severally mature. Unless otherwise
specified with respect to Securities of any series pursuant to Section 301, at
the option of the Company (upon written notice to the Trustee), all payments of
principal may be paid by check to the registered Holder of the Registered
Security or other person entitled thereto against surrender of such Security.

      SECTION 1002. Maintenance of Office or Agency. If Securities of a series
are issuable only as Registered Securities, the Company shall 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. If Securities of a
series are issuable as Bearer Securities, the Company will maintain: (A) in the
Borough of Manhattan, The City of New York, an office or agency where any
Registered Securities of that series may be presented or surrendered for
payment, where any Registered Securities of that series may be surrendered for
registration of transfer, where Securities of that series may be surrendered for
exchange, where notices and demands to or upon the Company in respect of the
Securities of that series and this Indenture may be served and where Bearer
Securities of that series and related coupons may be presented or surrendered
for payment in the circumstances described in the following paragraph (and not
otherwise); (B) subject to any laws or regulations applicable thereto, in a
Place of Payment for that series which is located outside the United States, an
office or agency where Securities of that series and related coupons may be
presented and surrendered for payment; provided, however, that if the Securities
of that series are listed on any stock exchange located outside the United
States and such stock exchange shall so require,

                                       63
<PAGE>
the Company will maintain a Paying Agent for the Securities of that series in
any required city located outside the United States, as the case may be, so long
as the Securities of that series are listed on such exchange; and (C) subject to
any laws or regulations applicable thereto, in a Place of Payment for that
series located outside the United States an office or agency where any
Registered Securities of that series may be surrendered for registration of
transfer, where Securities of that series may be surrendered for 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 of the location, and any change in the location,
of each such office or agency. If at any time the Company shall fail to maintain
any such required office or agency or shall fail to furnish the Trustee with the
address thereof, such presentations, surrenders, notices and demands may be made
or served at the Corporate Trust Office of the Trustee, except that Bearer
Securities of that series and the related coupons may be presented and
surrendered for payment at the offices specified in the Security, in London,
England, and the Company hereby appoints the same as its agent to receive such
respective presentations, surrenders, notices and demands, and the Company
hereby appoints the Trustee its agent to receive all such presentations,
surrenders, notices and demands.

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

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

                                       64
<PAGE>
receive all such presentations, surrenders, notices and demands each of the
Trustee, at its Corporate Trust Office, and State Street Bank and Trust Company,
N.A. at its offices at 61 Broadway, New York, NY 10005.

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

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

      Whenever the Company shall have one or more Paying Agents for any series
of Securities and any related coupons, it will, on or before each due date of
the principal of (and premium or Make-Whole Amount, if any), or interest on any
Securities of that series, deposit with a Paying Agent a sum (in the currency or
currencies, currency unit or units or composite currency or currencies described
in the preceding paragraph) sufficient to pay the principal (and premium or
Make-Whole Amount, if any) or interest so becoming due, such sum to be held in
trust for the benefit of the Persons entitled to such principal, premium or
Make-Whole Amount, if any, or interest and (unless such Paying Agent is the
Trustee) the Company will promptly notify the Trustee of its action or failure
so to act.

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

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

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

                                       65
<PAGE>
      premium or Make-Whole Amount, if any) or interest on the Securities of
      that series; and

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

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

      Except as otherwise provided in the Securities of any series, and subject
to applicable laws, any money deposited with the Trustee or any Paying Agent, or
then held by the Company, in trust for the payment of the principal of (and
premium or Make-Whole Amount, if any) or interest on any Security of any series
and remaining unclaimed for two years after such principal (and premium or
Make-Whole Amount, if any) or interest has become due and payable shall be paid
to the Company upon Company Request or (if then held by the Company) shall be
discharged from such trust; and the Holder of such Security shall thereafter, as
an unsecured general creditor, look only to the Company for payment of such
principal of (and premium or Make-Whole Amount, if any) or interest on any
Security, without interest thereon, and all liability of the Trustee or such
Paying Agent with respect to such trust money, and all liability of the Company
as trustee thereof, shall thereupon cease; provided, however, that the Trustee
or such Paying Agent, before being required to make any such repayment, may at
the expense of the Company cause to be published once, in an Authorized
Newspaper, notice that such money remains unclaimed and that, after a date
specified therein, which shall not be less than 30 days from the date of such
publication, any unclaimed balance of such money then remaining will be repaid
to the Company.

      SECTION 1004. Existence. Subject to Article Eight, the Company will do or
cause to be done all things necessary to preserve and keep in full force and
effect its corporate existence, all material rights (by articles of
incorporation, by-laws and statute) and material franchises; provided, however,
that the Company shall not be required to preserve any such right or franchise
if the Board of Directors shall determine that the preservation thereof is no
longer desirable in the conduct of the business of the Company.

      SECTION 1005. Maintenance of Properties. The Company will cause all of its
material properties used or useful in the conduct of its business or the
business of any Subsidiary to be maintained and kept in good condition, repair
and working order and supplied with all necessary equipment and will cause to be
made all necessary repairs, renewals,

                                       66
<PAGE>
replacements, betterments and improvements thereof, all as in the judgment of
the Company may be necessary so that the business carried on in connection
therewith may be properly and advantageously conducted at all times; provided,
however, that the Company and its Subsidiaries shall not be prevented from
selling or otherwise disposing of their properties for value in the ordinary
course of business.

      SECTION 1006. Insurance. The Company will cause each of its and its
Subsidiaries' insurable properties to be insured against loss or damage in an
amount deemed reasonable by the Board of Directors with insurers of recognized
responsibility.

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

      SECTION 1008. Statement as to Compliance. The Company will deliver to the
Trustee, within 120 days after the end of each fiscal year, a brief certificate
from the principal executive officer, principal financial officer or principal
accounting officer as to his or her knowledge of the Company's compliance with
all conditions and covenants under this Indenture and, in the event of any
noncompliance, specifying such noncompliance and the nature and status thereof.
For purposes of this Section 1008, such compliance shall be determined without
regard to any period of grace or requirement of notice under this Indenture.

      SECTION 1009. Waiver of Certain Covenants. The Company may omit in any
particular instance to comply with any term, provision or condition set forth in
Sections 1004 to 1008, inclusive, if before or after the time for such
compliance the Holders of at least a majority in principal amount of all
outstanding Securities of such series, by Act of such Holders, either waive such
compliance in such instance or generally waive compliance with such covenant or
condition, but no such waiver shall extend to or affect such covenant or
condition except to the extent so expressly waived, and, until such waiver shall
become effective, the obligations of the Company and the duties of the Trustee
in respect of any such term, provision or condition shall remain in full force
and effect.

                    ARTICLE ELEVEN - REDEMPTION OF SECURITIES

      SECTION 1101. Applicability of Article. Securities of any series which are
redeemable before their Stated Maturity shall be redeemable in accordance with
their terms and

                                       67
<PAGE>
(except as otherwise specified as contemplated by Section 301 for Securities of
any series) in accordance with this Article.

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

      SECTION 1103. Selection by Trustee of Securities to Be Redeemed. If less
than all the Securities of any series issued on the same day with the same terms
are to be redeemed, the particular Securities to be redeemed shall be selected
not more than 60 days prior to the Redemption Date by the Trustee, from the
Outstanding Securities of such series issued on such date with the same terms
not previously called for redemption, by such method as the Trustee shall deem
fair and appropriate and which may provide for the selection for redemption of
portions (equal to the minimum authorized denomination for Securities of that
series or any integral multiple thereof) of the principal amount of Securities
of such series of a denomination larger than the minimum authorized denomination
for Securities of that series.

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

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

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

                                       68
<PAGE>
      Any notice that is mailed to the Holders of Registered Securities in the
manner herein provided shall be conclusively presumed to have been duly given,
whether or not the Holder receives the notice.

      All notices of redemption shall state:

                  (1) the Redemption Date,

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

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

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

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

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

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

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

                  (9) if Bearer Securities of any series are to be redeemed and
      any Registered Securities of such series are not to be redeemed, and if
      such Bearer

                                       69
<PAGE>
      Securities may be exchanged for Registered Securities not subject to
      redemption on this Redemption Date pursuant to Section 305 or otherwise,
      the last date, as determined by the Company, on which such exchanges may
      be made, and

                  (10) the CUSIP number of such Security, if any.

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

      SECTION 1105. Deposit of Redemption Price. On or prior to any Redemption
Date, the Company shall deposit with the Trustee or with a Paying Agent (or, if
the Company is acting as its own Paying Agent, which it may not do in the case
of a sinking fund payment under Article Twelve, segregate and hold in trust as
provided in Section 1003) an amount of money in the currency or currencies,
currency unit or units or composite currency or currencies in which the
Securities of such series are payable (except as otherwise specified pursuant to
Section 301 for the Securities of such series) sufficient to pay on the
Redemption Date the Redemption Price of, and (except if the Redemption Date
shall be an Interest Payment Date) accrued interest on, all the Securities or
portions thereof which are to be redeemed on that date.

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

                                       70
<PAGE>
      If any Bearer Security surrendered for redemption shall not be accompanied
by all appurtenant coupons maturing after the Redemption Date, such Security may
be paid after deducting from the Redemption Price an amount equal to the face
amount of all such missing coupons, or the surrender of such missing coupon or
coupons may be waived by the Company and the Trustee if there be furnished to
them such security or indemnity as they may require to save each of them and any
Paying Agent harmless. If thereafter the Holder of such Security shall surrender
to the Trustee or any Paying Agent any such missing coupon in respect of which a
deduction shall have been made from the Redemption Price, such Holder shall be
entitled to receive the amount so deducted; provided, however, that interest
represented by coupons shall be payable only at an office or agency located
outside the United States (except as otherwise provided in Section 1002) and,
unless otherwise specified as contemplated by Section 301, only upon
presentation and surrender of those coupons.

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

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

                         ARTICLE TWELVE - SINKING FUNDS

      SECTION 1201. 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 301 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 such Securities of any series is herein referred to as an "optional
sinking fund payment." If provided for by the terms of any Securities of any
series, the cash amount of any mandatory sinking fund payment

                                       71
<PAGE>
may be subject to reduction as provided in Section 1202. 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 1202. Satisfaction of Sinking Fund Payments with Securities. The
Company may, in satisfaction of all or any part of any mandatory sinking fund
payment with respect to the Securities of a series, (1) deliver Outstanding
Securities of such series (other than any previously called for redemption)
together in the case of any Bearer Securities of such series with all unmatured
coupons appertaining thereto and (2) apply as a credit Securities of such 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, as provided for
by the terms of such Securities, or which have otherwise been acquired by the
Company; provided that such Securities so delivered or applied as a credit have
not been previously so credited. Such Securities shall be received and credited
for such purpose by the Trustee at the applicable Redemption Price specified in
such Securities for redemption through operation of the sinking fund and the
amount of such mandatory sinking fund payment shall be reduced accordingly.

      SECTION 1203. Redemption of Securities for Sinking Fund. Not less than 60
days prior to each sinking fund payment date for Securities of any series, the
Company will deliver to the Trustee an Officers' Certificate specifying the
amount of the next ensuing mandatory sinking fund payment for that series
pursuant to the terms of that series, the portion thereof, if any, which is to
be satisfied by payment of cash in the currency or currencies, currency unit or
units or composite currency or currencies in which the Securities of such series
are payable (except as otherwise specified pursuant to Section 301 for the
Securities of such series) and the portion thereof, if any, which is to be
satisfied by delivering and crediting Securities of that series pursuant to
Section 1202, and the optional amount, if any, to be added in cash to the next
ensuing mandatory sinking fund payment, and will also deliver to the Trustee any
Securities to be so delivered and credited. If such Officers' Certificate shall
specify an optional amount to be added in cash to the next ensuing mandatory
sinking fund payment, the Company shall thereupon be obligated to pay the amount
therein specified. 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 1103 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 1104. Such notice having been duly
given, the redemption of such Securities shall be made upon the terms and in the
manner stated in Sections 1106 and 1107.

              ARTICLE THIRTEEN - REPAYMENT AT THE OPTION OF HOLDERS

      SECTION 1301. Applicability of Article. Repayment of Securities of any
series before their Stated Maturity at the option of Holders thereof shall be
made in accordance with

                                       72
<PAGE>
the terms of such Securities, if any, and (except as otherwise specified by the
terms of such series established pursuant to Section 301) in accordance with
this Article.

      SECTION 1302. Repayment of Securities. Securities of any series subject to
repayment in whole or in part at the option of the Holders thereof will, unless
otherwise provided in the terms of such Securities, be repaid at a price equal
to the principal amount thereof, together with interest, if any, thereon accrued
to the Repayment Date specified in or pursuant to the terms of such Securities.
The Company covenants that on or prior to the Repayment Date it will deposit
with the Trustee or with a Paying Agent (or, if the Company is acting as its own
Paying Agent, segregate and hold in trust as provided in Section 1003) an amount
of money in the currency or currencies, currency unit or units or composite
currency or currencies in which the Securities of such series are payable
(except as otherwise specified pursuant to Section 301 for the Securities of
such series) sufficient to pay the principal (or, if so provided by the terms of
the Securities of any series, a percentage of the principal) of, and (except if
the Repayment Date shall be an Interest Payment Date) accrued interest on, all
the Securities or portions thereof, as the case may be, to be repaid on such
date.

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

                                       73
<PAGE>
if, following such repayment, the unpaid principal amount of such Security would
be less than the minimum authorized denomination of Securities of the series of
which such Security to be repaid is a part. Except as otherwise may be provided
by the terms of any Security providing for repayment at the option of the Holder
thereof, exercise of the repayment option by the Holder shall be irrevocable
unless waived by the Company.

      SECTION 1304. When Securities Presented for Repayment Become Due and
Payable. If Securities of any series providing for repayment at the option of
the Holders thereof shall have been surrendered as provided in this Article and
as provided by or pursuant to the terms of such Securities, such Securities or
the portions thereof, as the case may be, to be repaid shall become due and
payable and shall be paid by the Company on the Repayment Date therein
specified, and on and after such Repayment Date (unless the Company shall
default in the payment of such Securities on such Repayment Date) such
Securities shall, if the same were interest-bearing, cease to bear interest and
the coupons for such interest appertaining to any Bearer Securities so to be
repaid, except to the extent provided below, shall be void. Upon surrender of
any such Security for repayment in accordance with such provisions, together
with all coupons, if any, appertaining thereto maturing after the Repayment
Date, the principal amount of such Security so to be repaid shall be paid by the
Company, together with accrued interest, if any, to the Repayment Date;
provided, however, that coupons whose Stated Maturity is on or prior to the
Repayment Date shall be payable only at an office or agency located outside the
United States (except as otherwise provided in Section 1002) and, unless
otherwise specified pursuant to Section 301, only upon presentation and
surrender of such coupons; and provided further that, in the case of Registered
Securities, installments of interest, if any, whose Stated Maturity is on or
prior to the Repayment Date shall be payable (but without interest thereon,
unless the Company shall default in the payment thereof) to the Holders of such
Securities, or one or more Predecessor Securities, registered as such at the
close of business on the relevant Record Dates according to their terms and the
provisions of Section 307.

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

                                       74
<PAGE>
      If the principal amount of any Security surrendered for repayment shall
not be so repaid upon surrender thereof, such principal amount (together with
interest, if any, thereon accrued to such Repayment Date) shall, until paid,
bear interest from the Repayment Date at the rate of interest or Yield to
Maturity (in the case of Original Issue Discount Securities) set forth in such
Security.

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

              ARTICLE FOURTEEN - DEFEASANCE AND COVENANT DEFEASANCE

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

      SECTION 1402. Defeasance and Discharge. Upon the Company's exercise of the
above option applicable to this Section with respect to any Securities of or
within a series, the Company shall be deemed to have been discharged from its
obligations with respect to such Outstanding Securities and any coupons
appertaining thereto on the date the conditions set forth in Section 1404 are
satisfied (hereinafter, "defeasance"). For this purpose, such defeasance means
that the Company shall be deemed to have paid and discharged the entire
indebtedness represented by such Outstanding Securities and any coupons
appertaining thereto, which shall thereafter be deemed to be "Outstanding" only
for the purposes of Section 1405 and the other Sections of this Indenture
referred to in clauses (A) and (B) below, and to have satisfied all of its other
obligations under such Securities and any coupons appertaining thereto and this
Indenture insofar as such Securities and any coupons appertaining thereto are
concerned (and the Trustee, at the expense of the Company, shall execute proper
instruments acknowledging the same), except for the following which shall
survive until otherwise terminated or discharged hereunder: (A) the rights of
Holders of such Outstanding Securities

                                       75
<PAGE>
and any coupons appertaining thereto to receive, solely from the trust fund
described in Section 1404 and as more fully set forth in such Section, payments
in respect of the principal of (and premium or Make-Whole Amount, if any) and
interest, if any, on such Securities and any coupons appertaining thereto when
such payments are due, (B) the Company's obligations with respect to such
Securities under Sections 305, 306, 1002 and 1003, and the Company's obligations
under Section 606 hereof (C) the rights, powers, trusts, duties and immunities
of the Trustee hereunder and (D) this Article. Subject to compliance with this
Article Fourteen, the Company may exercise its option under this Section
notwithstanding the prior exercise of its option under Section 1403 with respect
to such Securities and any coupons appertaining thereto.

      SECTION 1403. Covenant Defeasance. Upon the Company's exercise of the
above option applicable to this Section with respect to any Securities of or
within a series, the Company shall be released from its obligations under
Sections 1004 to 1009, inclusive, and, if specified pursuant to Section 301, its
obligations under any other covenant contained herein or in any indenture
supplemental hereto, with respect to such Outstanding Securities and any coupons
appertaining thereto on and after the date the conditions set forth in Section
1404 are satisfied (hereinafter, "covenant defeasance"), and such Securities and
any coupons appertaining thereto shall thereafter be deemed to be not
"Outstanding" for the purposes of any direction, waiver, consent or declaration
or Act of Holders (and the consequences of any thereof) in connection with
Sections 1004 to 1009, inclusive, or such other covenant, but shall continue to
be deemed "Outstanding" for all other purposes hereunder. For this purpose, such
covenant defeasance means that, with respect to such Outstanding Securities and
any coupons appertaining thereto, the Company may omit to comply with and shall
have no liability in respect of any term, condition or limitation set forth in
any such Section or such other covenant, whether directly or indirectly, by
reason of any reference elsewhere herein to any such Section or such other
covenant or by reason of reference in any such Section or such other covenant to
any other provision herein or in any other document and such omission to comply
shall not constitute a default or an Event of Default under Section 501(4) or
501(8) or otherwise, as the case may be, but, except as specified above, the
remainder of this Indenture and such Securities and any coupons appertaining
thereto shall be unaffected thereby.

      SECTION 1404. Conditions to Defeasance or Covenant Defeasance. The
following shall be the conditions to application of Section 1402 or Section 1403
to any Outstanding Securities of or within a series and any coupons appertaining
thereto:

            (a) The Company shall irrevocably have deposited or caused to be
deposited with the Trustee (or another trustee satisfying the requirements of
Section 607 who shall agree to comply with the provisions of this Article
Fourteen applicable to it) as trust funds in trust for the purpose of making the
following payments, specifically pledged as security for, and dedicated solely
to, the benefit of the Holders of such Securities and any coupons appertaining
thereto, (1) an amount in such currency, currencies or currency unit in which
such Securities and any coupons appertaining thereto are then specified as
payable at Stated Maturity, or (2)

                                       76
<PAGE>
Government Obligations applicable to such Securities and coupons appertaining
thereto (determined on the basis of the currency, currencies or currency unit in
which such Securities and coupons appertaining thereto are then specified as
payable at Stated Maturity) which through the scheduled payment of principal and
interest in respect thereof in accordance with their terms will provide, not
later than the due date of any payment of principal of (and premium or
Make-Whole Amount, if any) and interest, if any, on such Securities and any
coupons appertaining thereto, money in an amount, or (3) a combination thereof,
in any case, in an amount, sufficient, without consideration of any reinvestment
of such principal and interest, in the opinion of a nationally recognized firm
of independent public accountants expressed in a written certification thereof
delivered to the Trustee, to pay and discharge, and which shall be applied by
the Trustee (or other qualifying trustee) to pay and discharge, (i) the
principal of (and premium or Make-Whole Amount, if any) and interest, if any, on
such Outstanding Securities and any coupons appertaining thereto on the Stated
Maturity of such principal or installment of principal or interest and (ii) any
mandatory sinking fund payments or analogous payments applicable to such
Outstanding Securities and any coupons appertaining thereto on the day on which
such payments are due and payable in accordance with the terms of this Indenture
and of such Securities and any coupons appertaining thereto.

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

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

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

            (e) In the case of an election under Section 1403, the Company shall
have delivered to the Trustee an Opinion of Counsel to the effect that the
Holders of such Outstanding Securities and any coupons appertaining thereto will
not recognize income, gain or loss for Federal income tax purposes as a result
of such covenant defeasance and will be

                                       77
<PAGE>
subject to Federal income tax on the same amounts, in the same manner and at the
same times as would have been the case if such covenant defeasance had not
occurred.

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

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

            (h) The payment of amounts payable to the Trustee pursuant to this
Indenture shall be paid or provided for to the reasonable satisfaction of the
Trustee.

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

      Unless otherwise specified with respect to any Security pursuant to
Section 301, if, after a deposit referred to in Section 1404(a) has been made,
(a) the Holder of a Security in respect of which such deposit was made is
entitled to, and does, elect pursuant to Section 301 or the terms of such
Security to receive payment in a currency or currency unit other than that in
which the deposit pursuant to Section 1404(a) has been made in respect of such
Security, or (b) a Conversion Event occurs in respect of the currency or
currency unit in which the deposit pursuant to Section 1404(a) has been made,
the indebtedness represented by such Security and any coupons appertaining
thereto shall be deemed to have been, and will be, fully discharged

                                       78
<PAGE>
and satisfied through the payment of the principal of (and premium or Make-Whole
Amount, if any), and interest, if any, on such Security as the same becomes due
out of the proceeds yielded by converting (from time to time as specified below
in the case of any such election) the amount or other property deposited in
respect of such Security into the currency or currency unit in which such
Security becomes payable as a result of such election or Conversion Event based
on the applicable market exchange rate for such currency or currency unit in
effect on the second Business Day prior to each payment date, except, with
respect to a Conversion Event, for such currency or currency unit in effect (as
nearly as feasible) at the time of the Conversion Event.

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

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

               ARTICLE FIFTEEN - MEETINGS OF HOLDERS OF SECURITIES

      SECTION 1501. Purposes for Which Meetings May Be Called. A meeting of
Holders of Securities of any series may be called at any time and from time to
time pursuant to this Article to make, give or take any request, demand,
authorization, direction, notice, consent, waiver or other action provided by
this Indenture to be made, given or taken by Holders of Securities of such
series.

      SECTION 1502. Call, Notice and Place of Meetings. (a) The Trustee may at
any time call a meeting of Holders of Securities of any series for any purpose
specified in Section 1501, to be held at such time and at such place as the
Trustee shall determine. Notice of every meeting of Holders of Securities of any
series, setting forth the time and the place of such meeting and in general
terms the action proposed to be taken at such meeting, shall be given, in the
manner provided in Section 106, not less than 20 nor more than 180 days prior to
the date fixed for the meeting.

            (b) In case at any time the Company, pursuant to a Board Resolution,
or the Holders of at least 25% in principal amount of the Outstanding Securities
of any series shall

                                       79
<PAGE>
have requested the Trustee to call a meeting of the Holders of Securities of
such series for any purpose specified in Section 1501, by written request
setting forth in reasonable detail the action proposed to be taken at the
meeting, and the Trustee shall not have made the first publication of the notice
of such meeting within 20 days after receipt of such request or shall not
thereafter proceed to cause the meeting to be held as provided herein, then the
Company or the Holders of Securities of such series in the amount above
specified, as the case may be, may determine the time and the place for such
meeting and may call such meeting for such purposes by giving notice thereof as
provided in subsection (a) of this Section.

      SECTION 1503. Persons Entitled to Vote at Meetings. To be entitled to vote
at any meeting of Holders of Securities of any series, a Person shall be (1) a
Holder of one or more Outstanding Securities of such series, or (2) a Person

more Outstanding Securities of such series by such Holder or Holders. The only
Persons who shall be entitled to be present or to speak at any meeting of
Holders of Securities of any series shall be the Persons entitled to vote at
such meeting and their counsel, any representatives of the Trustee and its

      SECTION 1504. Quorum; Action. The Persons entitled to vote a majority in
principal amount of the Outstanding Securities of a series shall constitute a

that if any action is to be taken at such meeting with respect to a consent or
waiver which this Indenture expressly provides may be given by the Holders of
not less than a specified percentage in principal amount of the Outstanding
Securities of a series, the Persons entitled to vote such specified percentage
in principal amount of the Outstanding Securities of such series shall
constitute a quorum. In the absence of a quorum within 30 minutes after the time

the chairman of the meeting prior to the adjournment of such meeting. In the
absence of a quorum at the reconvening of any such adjourned meeting, such
adjourned meeting may be further adjourned for a period of not less than 10
days; at the reconvening of any meeting adjourned or further adjourned for lack
of a quorum, the persons entitled to vote 25% in aggregate principal amount of
the then Outstanding Securities shall constitute a quorum for the taking of any
action set forth in the notice of the original meeting. Notice of the
reconvening of any adjourned meeting shall be given as provided in Section
1502(a), except that such notice need be given only once not less than five days
prior to the date on which the meeting is scheduled to be reconvened.

      Except as limited by the proviso to Section 902, any resolution presented
to a meeting or adjourned meeting duly reconvened at which a quorum is present
as aforesaid may be adopted by the affirmative vote of the persons entitled to
vote a majority in aggregate principal amount of the Outstanding Securities
represented at such meeting; provided, however, that, except as limited by the
proviso to Section 902, any resolution with respect to any request,

                                       80
<PAGE>
demand, authorization, direction, notice, consent, waiver or other action which
this Indenture expressly provides may be made, given or taken by the Holders of
a specified percentage, which is less than a majority, in principal amount of
the Outstanding Securities of a series may be adopted at a meeting or an
adjourned meeting duly reconvened and at which a quorum is present as aforesaid
by the affirmative vote of the Holders of such specified percentage in principal
amount of the Outstanding Securities of that series.

      Any resolution passed or decision taken at any meeting of Holders of
Securities of any series duly held in accordance with this Section shall be
binding on all the Holders of Securities of such series and the related coupons,
whether or not present or represented at the meeting.

      Notwithstanding the foregoing provisions of this Section 1504, if any
action is to be taken at a meeting of Holders of Securities of any series with
respect to any request, demand, authorization, direction, notice, consent,
waiver or other action that this Indenture expressly provides may be made, given
or taken by the Holders of a specified percentage in principal amount of all
Outstanding Securities affected thereby, or of the Holders of such series and
one or more additional series:

                  (i) there shall be no minimum quorum requirement for such
      meeting; and

                  (ii) the principal amount of the Outstanding Securities of
      such series that vote in favor of such request, demand, authorization,
      direction, notice, consent, waiver or other action shall be taken into
      account in determining whether such request, demand, authorization,
      direction, notice, consent, waiver or other action has been made, given or
      taken under this Indenture.

      SECTION 1505. Determination of Voting Rights; Conduct and Adjournment of
Meetings. (a) Notwithstanding any provisions of this Indenture, the Trustee may
make such reasonable regulations as it may deem advisable for any meeting of
Holders of Securities of a series in regard to proof of the holding of
Securities of such series and of the appointment of proxies and in regard to the
appointment and duties of inspectors of votes, the submission and examination of
proxies, certificates and other evidence of the right to vote, and such other
matters concerning the conduct of the meeting as it shall deem appropriate.
Except as otherwise permitted or required by any such regulations, the holding
of Securities shall be proved in the manner specified in Section 104 and the
appointment of any proxy shall be proved in the manner specified in Section 104
or by having the signature of the Person executing the proxy witnessed or
guaranteed by any trust company, bank or banker authorized by Section 104 to
certify to the holding of Bearer Securities. Such regulations may provide that
written instruments appointing proxies, regular on their face, may be presumed
valid and genuine without the proof specified in Section 104 or other proof.

                                       81
<PAGE>
            (b) The Trustee shall, by an instrument in writing appoint a
temporary chairman of the meeting, unless the meeting shall have been called by
the Company or by Holders of Securities as provided in Section 1502(b), in which
case the Company or the Holders of Securities of the series calling the meeting,
as the case may be, shall in like manner appoint a temporary chairman. A
permanent chairman and a permanent secretary of the meeting shall be elected by
vote of the Persons entitled to vote a majority in principal amount of the
Outstanding Securities of such series represented at the meeting.

            (c) At any meeting each Holder of a Security of such series or proxy
shall be entitled to one vote for each $1,000 principal amount of the
Outstanding Securities of such series held or represented by him; provided,
however, that no vote shall be cast or counted at any meeting in respect of any
Security challenged as not Outstanding and ruled by the chairman of the meeting
to be not Outstanding. The chairman of the meeting shall have no right to vote,
except as a Holder of a Security of such series or proxy.

            (d) Any meeting of Holders of Securities of any series duly called
pursuant to Section 1502 at which a quorum is present may be adjourned from time
to time by Persons entitled to vote a majority in principal amount of the
Outstanding Securities of such series represented at the meeting, and the
meeting may be held as so adjourned without further notice.

      SECTION 1506. Counting Votes and Recording Action of Meetings. The vote
upon any resolution submitted to any meeting of Holders of Securities of any
series shall be by written ballots on which shall be subscribed the signatures
of the Holders of Securities of such series or of their representatives by proxy
and the principal amounts and serial numbers of the Outstanding Securities of
such series held or represented by them. The permanent chairman of the meeting
shall appoint two inspectors of votes who shall count all votes cast at the
meeting for or against any resolution and who shall make and file with the
secretary of the meeting their verified written reports in duplicate of all
votes cast at the meeting. A record, at least in duplicate, of the proceedings
of each meeting of Holders of Securities of any Series shall be prepared by the
secretary of the meeting and there shall be attached to said record the original
reports of the inspectors of votes on any vote by ballot taken thereat and
affidavits by one or more persons having knowledge of the fact, setting forth a
copy of the notice of the meeting and showing that said notice was given as
provided in Section 1502 and, if applicable, Section 1504. Each copy shall be
signed and verified by the affidavits of the permanent chairman and secretary of
the meeting and one such copy shall be delivered to the Company and another to
the Trustee to be preserved by the Trustee, the latter to have attached thereto
the ballots voted at the meeting. Any record so signed and verified shall be
conclusive evidence of the matters therein stated.

caption "Treasury Constant Maturities" for the maturity (rounded to the nearest
month) corresponding to the remaining life to maturity, as of the payment date

corresponding to such maturity shall be calculated pursuant to the immediately
preceding sentence and the Reinvestment Rate shall be interpolated or

      The following provisions of this Article Two are made pursuant to Section
301 of the Senior Indenture in order to establish and set forth the terms of the
series of Securities described in Section 2.1.

      SECTION 2.1. Title of the Securities. There shall be a series of
Securities designated the "6.250% Senior Notes due 2003" (the "2003 Notes"), a
series of Securities designated the "6.500% Senior Notes due 2005" (the "2005
Notes") and a series of Securities designated the "6.625% Senior Notes due 2008"
(the "2008 Notes" and, together with the 2003 Notes and the 2005 Notes, the
"Notes").

      SECTION 2.2. Limitation on Aggregate Principal Amount.

      (1) The aggregate principal amount of the 2003 Notes shall be limited to
$50,000,000, and, except as provided in this Section and in Section 306 of the
Senior Indenture, the Company shall not execute and the Trustee shall not
authenticate or deliver 2003 Notes in excess of such aggregate principal amount.

      (2) The aggregate principal amount of the 2005 Notes shall be limited to
$50,000,000, and, except as provided in this Section and in Section 306 of the
Senior Indenture, the Company shall not execute and the Trustee shall not
authenticate or deliver 2005 Notes in excess of such aggregate principal amount.

      (3) The aggregate principal amount of the 2008 Notes shall be limited to
$50,000,000, and, except as provided in this Section and in Section 306 of the
Senior Indenture, the Company shall not execute and the Trustee shall not
authenticate or deliver 2008 Notes in excess of such aggregate principal amount.

      Nothing contained in this Section 2.2 or elsewhere in this Supplemental
Indenture, or in the Notes, is intended to or shall limit execution by the
Company or authentication or delivery by the Trustee of Notes under the
circumstances contemplated by Sections 303, 304, 305, 306, 906, 1107 and 1305 of
the Senior Indenture.

      SECTION 2.3. Interest and Interest Rates; Maturity Date of Notes. The 2003
Notes will bear interest at a rate of 6.250% per annum, the 2005 Notes will bear
interest at a rate of 6.500% per annum and the 2008 Notes will bear interest at
a rate of 6.625% per annum, in each case, from January 15, 1998 or from the
immediately preceding Interest Payment Date to which interest has been paid or
duly provided for, payable semi-annually in arrears on January 15 and July 15 of
each year, commencing July 15, 1998 (each, an "Interest Payment Date"), to the
Person in whose name such Note is registered at the close of business on
December 31 or June 30 (whether or not a Business Day), as the case may be, next

                                        7
<PAGE>
preceding such Interest Payment Date (each, a "Regular Record Date"). Interest
will be computed on the basis of a 360-day year comprised of twelve 30-day
months. The interest so payable on any Note which is not punctually paid or duly
provided for on any Interest Payment Date shall forthwith cease to be payable to
the Person in whose name such Note is registered on the relevant Regular Record
Date, and such defaulted interest shall instead be payable to the Person in
whose name such Note is registered on the Special Record Date or other specified
date determined in accordance with the Senior Indenture.

      If any Interest Payment Date or Maturity falls on a day that is not a
Business Day, the required payment shall be made on the next Business Day as if
it were made on the date such payment was due and no interest shall accrue on
the amount so payable for the period from and after such Interest Payment Date
or Maturity, as the case may be.

      The 2003 Notes will mature on January 15, 2003, the 2005 Notes will mature
on January 15, 2005 and the 2008 Notes will mature on January 15, 2008.

      SECTION 2.4. Limitations on Incurrence of Indebtedness.

            (1) The Company will not, and will not permit any Subsidiary to,
incur any Indebtedness if, immediately after giving effect to the incurrence of
such additional Indebtedness and the application of the proceeds thereof, the
aggregate principal amount of all outstanding Indebtedness of the Company and
its Subsidiaries on a consolidated basis determined in accordance with GAAP is
greater than 60% of the sum of (without duplication) (i) the Total Assets of the
Company and its Subsidiaries as of the end of the calendar quarter covered in
the Company's Annual Report on Form 10-K or Quarterly Report on Form 10-Q, as
the case may be, most recently filed with the Commission (or, if such filing is
not permitted under the Exchange Act, with the Trustee) prior to the incurrence
of such additional Indebtedness and (ii) the purchase price of any real estate
assets or mortgages receivable acquired, and the amount of any securities
offering proceeds received (to the extent that such proceeds were not used to
acquire real estate assets or mortgages receivable or used to reduce
Indebtedness), by the Company or any Subsidiary since the end of such calendar
quarter, including those proceeds obtained in connection with the incurrence of
such additional Indebtedness.

            (2) In addition to the limitation set forth in subsection (1) of
this Section 2.4, the Company will not, and will not permit any Subsidiary to,
incur any Indebtedness if the ratio of Consolidated Income Available for Debt
Service to the Annual Service Charge for the four consecutive fiscal quarters
most recently ended prior to the date on which such additional Indebtedness is
to be incurred shall have been less than 1.5:1, on a pro forma basis after
giving effect thereto and to the application of the proceeds therefrom, and
calculated on the assumption that (i) such Indebtedness and any other
Indebtedness incurred by the Company and its Subsidiaries since the first day of
such four-quarter period and the application of the proceeds therefrom,
including to refinance other Indebtedness, had occurred at the beginning

                                        8
<PAGE>
of such period; (ii) the repayment or retirement of any other Indebtedness by
the Company and its Subsidiaries since the first day of such four-quarter period
had been repaid or retired at the beginning of such period (except that, in
making such computation, the amount of Indebtedness under any revolving credit
facility shall be computed based upon the average daily balance of such
Indebtedness during such period); (iii) in the case of Acquired Indebtedness or
Indebtedness incurred in connection with any acquisition since the first day of
such four-quarter period, the related acquisition had occurred as of the first
day of such period with the appropriate adjustments with respect to such
acquisition being included in such pro forma calculation; and (iv) in the case
of any acquisition or disposition by the Company or its Subsidiaries of any
asset or group of assets since the first day of such four-quarter period,
whether by merger, stock purchase or sale, or asset purchase or sale, such
acquisition or disposition or any related repayment of Indebtedness had occurred
as of the first day of such period with the appropriate adjustments with respect
to such acquisition or disposition being included in such pro forma calculation.

            (3) In addition to the limitations set forth in subsections (1) and
(2) of this Section 2.4, the Company will not, and will not permit any
Subsidiary to, incur any Indebtedness secured by any Encumbrance upon any of the
property of the Company or any Subsidiary if, immediately after giving effect to
the incurrence of such additional Indebtedness and the application of the
proceeds thereof, the aggregate principal amount of all outstanding Indebtedness
of the Company and its Subsidiaries on a consolidated basis which is secured by
any Encumbrance on property of the Company or any Subsidiary is greater than 40%
of the sum of (without duplication) (i) the Total Assets of the Company and its
Subsidiaries as of the end of the calendar quarter covered in the Company's
Annual Report on Form 10-K or Quarterly Report on Form 10-Q, as the case may be,
most recently filed with the Commission (or, if such filing is not permitted
under the Exchange Act, with the Trustee) prior to the incurrence of such
additional Indebtedness and (ii) the purchase price of any real estate assets or
mortgages receivable acquired, and the amount of any securities offering
proceeds received (to the extent that such proceeds were not used to acquire
real estate assets or mortgages receivable or used to reduce Indebtedness), by
the Company or any Subsidiary since the end of such calendar quarter, including
those proceeds obtained in connection with the incurrence of such additional
Indebtedness.

            (4) The Company and its Subsidiaries may not at any time own Total
Unencumbered Assets equal to less than 150% of the aggregate outstanding
principal amount of the Unsecured Indebtedness of the Company and its
Subsidiaries on a consolidated basis.

            (5) For purposes of this Section 2.4, Indebtedness shall be deemed
to be "incurred" by the Company or a Subsidiary whenever the Company or such
Subsidiary shall create, assume, guarantee or otherwise become liable in respect
thereof.

      SECTION 2.5. Redemption. The Notes may be redeemed at any time at the
option of the Company, in whole or in part, at a redemption price equal to the

      SECTION 2.12. Defeasance. The provisions of Sections 1402 and 1403 of the
Senior Indenture, together with the other provisions of Article Fourteen of the

      SECTION 2.13. Events of Default. The provisions of clause (5) of Section

deemed to be amended and restated in their entirety to read as follows:

            (5) default under any bond, debenture, note, mortgage, indenture or
instrument under which there may be issued or by which there may be secured or
evidenced any indebtedness for money borrowed by the Company (or by any
Subsidiary, the repayment of which the Company has guaranteed or for which the
Company is directly responsible or liable as obligor or guarantor), having an
aggregate principal amount outstanding of at least $10,000,000, whether such
indebtedness now exists or shall hereafter be created, which default shall have
resulted in such indebtedness becoming or being declared due and payable prior
to the date on which it would otherwise have become due and payable, without
such indebtedness having been discharged, or such acceleration having been
rescinded or annulled, within a period of 10 days after there shall have been
given written notice, by registered or certified mail, to the Company by the
Trustee or to the Company and the Trustee by the Holders of at least 10% in
principal amount of the Outstanding Securities of that series a written notice
specifying such default and requiring the Company to cause such indebtedness to
be discharged or cause such acceleration to be rescinded or annulled and stating
that such notice is a "Notice of Default" hereunder; provided, however, that
such a default on indebtedness which constitutes tax-exempt financing having an
aggregate principal amount outstanding not exceeding $25,000,000 that results
solely from a failure of an entity providing credit support for such
indebtedness to honor a demand for payment on a letter of credit shall not
constitute an Event of Default.

      SECTION 2.14. Acceleration of Maturity; Rescission and Annulment. The
provisions of the first paragraph of Section 502 of the Senior Indenture as
applicable with respect to the Notes shall be deemed to be amended and restated
in their entirety to read as follows:

            If an Event of Default 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 that series may declare the principal amount (or, if
Securities of that series are Original Issue Discount Securities or Indexed
Securities, such portion of the principal as may be specified in the terms
thereof) of, and the Make-Whole Amount, if any, on, all the Securities of that
series to be due and payable immediately, by a notice in writing to the Company
(and to the Trustee if given by the Holders), and upon any such declaration such
principal or specified portion thereof shall

                                       11
<PAGE>
become immediately due and payable. If an Event of Default with respect to the
Securities of any series set forth in Section 501(6) of the Senior Indenture
occurs and is continuing, then in every such case all the Securities of that
series shall become immediately due and payable, without notice to the Company,
at the principal amount thereof (or, if any Securities are Original Issue
Discount Securities or Indexed Securities, such portion of the principal as may
be specified in the terms thereof) plus accrued interest to the date the
Securities of that series are paid, plus the Make-Whole Amount, if any, on the
Securities of that series.

      SECTION 2.15. Provision of Financial Information. Whether or not the
Company is subject to Section 13 or 15(d) of the Exchange Act, the Company will,
to the extent permitted under the Exchange Act, file with the Commission the
annual reports, quarterly reports and other documents which the Company would
have been required to file with the Commission pursuant to such Section 13 or
15(d) if the Company were so subject, such documents to be filed with the
Commission on or prior to the respective dates (the "Required Filing Dates") by
which the Company would have been required so to file such documents if the
Company were so subject.

      The Company will also in any event (x) within 15 days of each Required
Filing Date (i) if the Company is not then subject to Section 13 or 15(d) of the
Exchange Act, transmit by mail to all Holders, as their names and addresses
appear in the Security Register, without cost to such Holders, copies of the
annual reports, quarterly reports and other documents which the Company would
have been required to file with the Commission pursuant to Section 13 or 15(d)
of the Exchange Act if the Company were subject to such Sections and (ii) file
with the Trustee copies of annual reports, quarterly reports and other documents
which the Company is required to file with the Commission or would have been
required to file with the Commission pursuant to Section 13 or 15(d) of the
Exchange Act if the Company were subject to such Sections and (y) supply,
promptly upon written request and payment of the reasonable cost of duplication
and delivery, copies of such documents to any prospective Holder.

      The Trustee shall not be required to examine any of the reports and other
documents filed therewith pursuant to the provisions of this Section 2.15 or
Section 7.03 of the Senior Indenture in order to determine whether the Company
is in compliance with the provisions of Section 2.4 of this Supplemental
Indenture.

      SECTION 2.16. Waiver of Certain Covenants. Notwithstanding the provisions
of Section 1009 of the Senior Indenture, the Company may omit in any particular
instance to comply with any term, provision or condition set forth in Sections
1004 to 1008, inclusive, of the Senior Indenture, with Sections 2.4 and 2.15 of
this Supplemental Indenture and with any other term, provision or condition with
respect to the Notes (except any such term, provision or condition which could
not be amended without the consent of all Holders of the Notes or such series
thereof, as applicable), if before or after the time for such compliance the
Holders of at least a majority in principal amount of all outstanding Notes, by
Act of such Holders, either waive such compliance in such instance or generally
waive compliance with such

                                       12
<PAGE>
covenant or condition. Except to the extent so expressly waived, and until such
waiver shall become effective, the obligations of the Company and the duties of
the Trustee in respect of any such term, provision or condition shall remain in
full force and effect.

                    ARTICLE THREE - MISCELLANEOUS PROVISIONS.

      SECTION 3.1. Ratification of Senior Indenture. Except as expressly
modified or amended hereby, the Senior Indenture continues in full force and
