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

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
and, where it is hereby expressly required, to the Trust. Such instrument or
instruments and any such record (and the action embodied therein and evidenced

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 Trust and any
agent of the Trustee or the Trust, 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.

11
18
(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 Trust 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 Trust shall solicit from the Holders of
Registered Securities any request, demand, authorization, direction, notice,
consent, waiver or other Act, the Trust 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 Trust shall have no obligation to do so.
Notwithstanding TIA Section 316(c), such record date shall be the record date
specified in or pursuant to such Board Resolution, which shall be a date not
earlier than the date 30 days prior to the first solicitation of Holders
generally in connection therewith and not later than the date such solicitation
is completed. If such a record date is fixed, such request, demand,
authorization, direction, notice, consent, waiver or other Act may be given
before or after such record date, but only the Holders of record at the close
of business on such record date shall be deemed to be Holders for the purposes
of determining whether Holders of the requisite proportion of Outstanding
Securities have authorized or agreed or consented to such 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.

12
19
(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 Trust in reliance thereon, whether or not notation of such action is made
upon such Security.

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 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 parties hereto shall bind their respective successors and
assigns, whether so expressed or not.

21
SECTION 109. SEVERABILITY CLAUSE. In case any provision in this
Indenture or in any Security or coupon shall be invalid, illegal or
unenforceable under any current or future law, and if the rights or obligations
of any of the parties as a whole would not be materially affected thereby, such
provision shall be fully separable, and this Indenture shall be construed and
enforced as if such illegal, invalid or unenforceable provision had never
comprised a part thereof and the remaining provisions of this Indenture shall
remain in full force and effect and shall not be effected by the illegal,
invalid or unenforceable provision or by its severance therefrom. In lieu of
such illegal, invalid or unenforceable provision, there shall be added
automatically as a part of this Indenture a legal, valid and enforceable
provision as similar in terms and effect to such illegal, invalid or
unenforceable provision as may be possible, and the parties hereto request the
court to whom disputes relating to this Indenture or the Securities are
submitted to reform the otherwise illegal, invalid or unenforceable provision
in accordance with this Section 109.

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 Texas. 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 convert or 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 any Additional Amounts or principal (and
premium or Make-Whole Amount, if any) or conversion 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 conversion or 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, if such amount
is so paid on the next succeeding Business Day.

SECTION 113. IMMUNITY OF SHAREHOLDERS, TRUST MANAGERS OR DIRECTORS,
OFFICERS AND AGENTS OF THE TRUST. 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

15
22
had against any past, present or future shareholder, employee, officer, trust
manager or director, as such, of the Trust or of any successor, either directly
or through the Trust 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 Trust 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 securities 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:

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 (16) 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 by the Trustee in such manner or by such Person or
Persons as shall be specified therein or in the Trust 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 Trust Order. If a Trust Order pursuant to Section 303 or 304 has
been, or simultaneously is, delivered, any instructions by the Trust 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 Trust and the Trust 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 Amount, if any, and interest on any Global Security in
permanent global form shall be made to the Person or Persons specified therein.

Notwithstanding the provisions of Section 308 and except as provided
in the preceding paragraph, the Trust, the Trustee and any agent of the Trust
and the Trustee shall treat a Person as the Holder of such principal amount of
Outstanding Securities represented by a permanent Global Security as shall be
specified in a written statement of the Holder of such permanent Global
Security.

17
24
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."

permanent global Security may exchange such interests for Securities
of such series and of like tenor of any authorized form and
denomination and the circumstances under which any such exchanges may

or conditions;

issued upon the exercise of warrants, the time, manner and place for
such Securities to be authenticated and delivered;

(22) whether and under what circumstances the
Trust will pay Additional Amounts as contemplated by Section 1010 on
the Securities of the series to any Holder who is not a United States

All Securities of any one series and the coupons appertaining to any

21
28
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 Trust 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 Trust by its Chairman of the Board, its President, one of its Vice
Presidents, or its Treasurer or one of its Assistant Treasurers, 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 Trust shall bind
the Trust, 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 Trust may deliver Securities of any series, together with
any coupon appertaining thereto, executed by the Trust to the Trustee for
authentication, together with a Trust Order for the authentication and delivery
of such Securities, and the Trustee in accordance with the Trust Order shall
authenticate and deliver such Securities; provided, however, that, in
connection with its original issuance, no Bearer Security shall be mailed or
otherwise delivered to any location in the United States; and provided further
that, unless otherwise specified with respect to any series of Securities
pursuant to Section 301, a Bearer Security may be delivered in connection with
its original issuance only if the Person entitled to receive such Bearer
Security shall have furnished a certificate to the Trustee or 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 with respect to any
series

22
29
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 Trust 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 Trust 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 Trust in the manner and
subject to any conditions specified in such Opinion of
Counsel, will constitute legal, valid and legally binding
obligations of the Trust, 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 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.

23
30
If such form or terms have been so established, the Trustee shall not be
required to authenticate such Securities if the issue of such Securities
pursuant to this Indenture will affect the Trustee's own rights, duties,
obligations or immunities under the Securities and this Indenture or otherwise
in a manner which is not reasonably acceptable to the Trustee.

Notwithstanding the provisions of Section 301 and of the preceding
paragraph, if all the Securities of any series are not to be issued at one
time, it shall not be necessary to deliver an Officers' Certificate otherwise
required pursuant to Section 301 or a Trust 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 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 Trust,
and the Trust 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 Trust, 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 Trust may execute, and upon Trust 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.

24
31
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), if temporary Securities of any series are issued, the
Trust 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 Trust 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 Trust 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, 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
(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 Trust shall deliver to the Trustee
definitive Securities, in aggregate principal amount equal to the principal
amount of such temporary Global Security, executed by the Trust. On or after
the Exchange Date, such temporary Global Security shall be surrendered by the
Common Depository to the Trustee, as the Trust's agent for such purpose, to be
exchanged, in whole or from time to time in part, for definitive Securities
without charge, and the Trustee shall authenticate and deliver, in exchange for
each portion of such temporary Global Security, an equal aggregate principal
amount of definitive Securities of the same series of authorized denominations
and of like tenor as the portion of such temporary Global Security to be
exchanged. The definitive Securities to be delivered in exchange for any such
temporary Global Security shall be in bearer form, registered form, permanent
global bearer form or permanent global registered form, or any combination
thereof, as specified as contemplated by Section 301, and, if any combination
thereof is so specified, as requested by the beneficial owner thereof;
provided, however, that, unless otherwise specified in such temporary Global
Security, upon such presentation by the Common Depository, such temporary
Global Security is 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

25
32
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
such 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 outside the
United States.

Until exchanged in full as hereinabove provided, the temporary
Securities of any series shall in all respects be entitled to the same benefits
under this Indenture as definitive Securities of the same series and of like
tenor authenticated and delivered hereunder, except that, unless otherwise
specified as contemplated by Section 301, interest payable on a temporary
Global Security on an Interest Payment Date for Securities of such series
occurring prior to the applicable Exchange Date shall be payable to Euroclear
and CEDEL on such Interest Payment Date upon delivery by Euroclear and CEDEL to
the Trustee of a certificate or certificates in the form set forth in Exhibit
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

26
33
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 Trust.

SECTION 305. REGISTRATION, REGISTRATION OF TRANSFER AND EXCHANGE.
The Trust shall cause to be kept at the Corporate Trust Office of the Trustee
or in any office or agency of the Trust 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 Trust 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 Trust shall provide for the
registration of Registered Securities and of transfers of Registered
Securities. The Security Register shall be in written form or any other form
capable of being converted into written form within a reasonable time. The
Trustee, at its Corporate Trust Office, is hereby initially appointed "Security
Registrar" for the purpose of registering Registered Securities and transfers
of Registered Securities on such Security Register as herein provided. In the
event that the Trustee shall cease to be Security Registrar, it shall have the
right to examine the Security Register at all reasonable times.

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

Subject to the provisions of this Section 305, at the option of the
Holder, Registered Securities of any series may be exchanged for other
Registered Securities of the same series, of any authorized denomination or
denominations and of a like aggregate principal amount, containing identical
terms and provisions, upon surrender of the Registered Securities to be
exchanged at any such office or agency. Whenever any such Registered
Securities are so surrendered for exchange, the Trust 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

27
34
to the Trust 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 Trust 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 accordance
with the provisions of this Indenture. Whenever any Securities are so
surrendered for exchange, the Trust 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 Trust 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 Trust
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 Trust within 90 days after the Trust
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 Trust, 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 Trust shall execute, and the Trustee shall
authenticate and

28
35
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 Trust 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 Trust Order with respect thereto
to the Trustee, as the Trust's agent for such purpose; provided, however, that
no such exchanges may occur during a period beginning at the opening of
business 15 days before any selection of Securities to be redeemed and ending
on the relevant Redemption Date if the Security for which exchange is requested
may be among those selected for redemption; and provided further that no Bearer
Security delivered in exchange for a portion of a permanent Global Security
shall be mailed or otherwise delivered to any location in the United States.
If a Registered Security is issued in exchange for any portion of a permanent
Global Security after the close of business at the office or agency where such
exchange occurs on (i) any Regular Record Date and before the opening of
business at such office or agency on the relevant Interest Payment Date, or
(ii) any Special Record Date and before 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 Trust, 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 Trust or
the Security Registrar) be duly endorsed, or be accompanied by a written
instrument of transfer in form satisfactory to the Trust 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 Trust 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.

29
36
The Trust or the Trustee, as applicable, shall not be required (i) to
issue, register the transfer of or exchange any Security if such Security may
be among those selected for redemption during a period beginning at the opening
of business 15 days before selection of the Securities to be redeemed under
Section 1103 and ending at the close of business on (A) if such Securities are
issuable only as Registered Securities, the day of the mailing of the relevant
notice of redemption and (B) if such Securities are issuable as Bearer
Securities, the day of the first publication of the relevant notice of
redemption or, if such Securities are also issuable as Registered Securities
and there is no publication, the mailing of the relevant notice of redemption,
or (ii) to register the transfer of or exchange any Registered Security so
selected for redemption in whole or in part, except, in the case of any
Registered Security to be redeemed in part, the portion thereof not to be
redeemed, or (iii) to exchange any Bearer Security so selected for redemption
except that such a Bearer Security may be exchanged for a Registered Security
of that series and like tenor, provided that such Registered Security shall be
simultaneously surrendered for redemption, or (iv) to issue, register the
transfer of or exchange any Security which has been surrendered for repayment
at the option of the Holder, except the portion, if any, of such Security not
to be so repaid.

SECTION 306. MUTILATED, DESTROYED, LOST AND STOLEN SECURITIES. If
any mutilated Security or a Security with a mutilated coupon appertaining to it
is surrendered to the Trustee or the Trust, together with, in proper cases,
such security or indemnity as may be required by the Trust or the Trustee to
save each of them or any agent of either of them harmless, the Trust 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 Trust 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 Trust or the Trustee that such Security or coupon
has been acquired by a bona fide purchaser, the Trust 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 Trust in its discretion may, instead of
issuing a new Security, with coupons corresponding to

30
37
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), any interest on and any Additional
Amounts with respect to, 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 Trust
may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation thereto and any other
expenses (including the fees and expenses of the Trustee) connected therewith.

Every new Security of any series with its coupons, if any, issued
pursuant to this Section in lieu of any destroyed, lost or stolen Security, or
in exchange for a Security to which a destroyed, lost or stolen coupon
appertains, shall constitute an original additional contractual obligation of
the Trust, 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 Trust maintained
for such purpose pursuant to Section 1002; provided, however, that each
installment of interest on any Registered Security may at the Trust'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) wire 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 (i) must be

31
38
received by the Trustee, in immediately available funds, by 11:00 a.m. New York
time, on the Interest Payment date, and (ii) 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.

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 Trust, at its election in each case,
as provided in clause (1) or (2) below:

(1) The Trust 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 Trust 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 Trust 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 Trust of such Special Record Date and, in the name and at the
expense of the Trust, shall cause notice of the proposed payment of
such Defaulted Interest and the

32
39
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 Trust, cause a
similar notice to be published at least once in an Authorized
Newspaper in each Place of Payment, but such publications shall not be
a condition precedent to the establishment of such Special Record
Date. Notice of the proposed payment of such Defaulted Interest and
the Special Record Date therefor having been mailed as aforesaid, such
Defaulted Interest shall be paid to the Persons in whose names the
Registered Securities of such series (or their respective Predecessor
Securities) are registered at the close of business on such Special
Record Date and shall no longer be payable pursuant to the following
clause (2). In case a Bearer Security of any series is surrendered at
the office or agency in a Place of Payment for such series in exchange
for a Registered Security of such series after the close of business
at such office or agency on any Special Record Date and before the
opening of business at such office or agency on the related proposed
date for payment of Defaulted Interest, such Bearer Security shall be
surrendered without the coupon relating to such proposed date of
payment and Defaulted Interest will not be payable on such proposed
date of payment in respect of the Registered Security issued in
exchange for such 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 Trust 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
Trust 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 Trust, the Trustee and
any agent of the Trust 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 Trust, the Trustee nor any agent of the
Trust 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.

33
40
Title to any Bearer Security and any coupons appertaining thereto
shall pass by delivery. The Trust, the Trustee and any agent of the Trust 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
Trust, the Trustee nor any agent of the Trust 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 shall be treated by the
Trust, the Trustee, and any agent of the Trust or the Trustee as the owner of
such Global Security for all purposes whatsoever. None of the Trust, the
Trustee, any Paying Agent or the Security Registrar will have any
responsibility or liability for any aspect of the records relating to or
payments made on account of beneficial ownership interests of a Global Security
or for maintaining, supervising or reviewing any records relating to such
beneficial ownership interests.

Notwithstanding the foregoing, with respect to any Global Security,
nothing herein shall prevent the Trust, the Trustee, or any agent of the Trust
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 conversion or for credit against any sinking fund
payment shall, if surrendered to any Person other than the Trustee, be
delivered to the Trustee (at the address below), and any such Securities and
coupons and Securities and coupons surrendered directly to the Trustee for any
such purpose shall be promptly canceled by it. The Trust may at any time
deliver to the Trustee (at the address below) for cancellation any Securities
previously authenticated and delivered hereunder which the Trust 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 Trust has not issued and sold, and
all Securities so delivered shall be promptly canceled by the Trustee. If the
Trust 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 (at the address below). No Securities shall be authenticated in
lieu of or in exchange for any Securities canceled as provided in this Section,
except as expressly permitted by this Indenture. Canceled Securities and
coupons held by the Trustee shall be destroyed by the Trustee and the Trustee
shall deliver a certificate of such destruction to the Trust, unless the
Trustee is otherwise directed by a Trust Order. Deliveries of all Securities
to be canceled should be made, by United States mail (preferably insured and
certified) to _________________________________________________________, Attn:
Corporate Trust Department.

34
41
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 Trust Request cease to be of further effect with respect to any
series of Securities specified in such Trust Request (except as to any
surviving rights of registration of transfer or exchange of Securities of such
series herein expressly provided for and any right to receive Additional
Amounts, as provided in Section 1010), and the Trustee, upon receipt of a Trust
Order, and at the expense of the Trust, shall execute instruments in form and
substance satisfactory to the Trustee and the Trust acknowledging satisfaction
and discharge of this Indenture as to such series when

Securities and maturing after such exchange, whose surrender
is not required or has been waived as provided in ▇▇▇▇▇▇▇ ▇▇▇,
(▇▇) Securities and coupons of such series which have been
destroyed, lost or stolen and which have been replaced or paid
as provided in ▇▇▇▇▇▇▇ ▇▇▇, (▇▇▇) 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
Trust and thereafter repaid to the Trust 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

Stated Maturity within one year, or

35
42
(iii) if redeemable at the option of the
Trust, 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 Trust,

and the Trust, 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

Notwithstanding the satisfaction and discharge of this Indenture, the
obligations of the Trust to the Trustee and any predecessor Trustee under
Section 606, the obligations of the Trust to any Authenticating Agent under
Section 611 and, if money shall have been deposited with and held by 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 Trust
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 and Additional Amounts 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.

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

36
43
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 or
any Additional Amounts payable in respect of any Security of that
series or of any coupon appertaining thereto, when such interest,
Additional Amounts or coupon becomes due and payable, and continuance
of such default for a period of 30 days; or

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

(3) default in the 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 Trust 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 Trust by the Trustee or to the
Trust 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 Trust (or by any Subsidiary, the repayment of which
the Trust has guaranteed or for which the Trust 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 30 days after there shall have been given, by
registered or certified mail, to the Trust by the Trustee or to the
Trust 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 and requiring the Trust 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; or

37
44
(6) the entry by a court of competent
jurisdiction of one or more judgments, orders or decrees against the
Trust or any of its Subsidiaries in an aggregate amount (excluding
amounts covered by insurance) in excess of $10,000,000 and such
judgments, orders or decrees remain undischarged, unstayed and
unsatisfied in an aggregate amount (excluding amounts covered by
insurance) in excess of $10,000,000 for a period of 30 consecutive
days; or

for relief against it in an involuntary case,

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

(8) a court of competent jurisdiction enters an

any Significant Subsidiary or for all or substantially all of
either of its property, or

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

(9) 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.

45
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 Trust (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 Trust and the
Trustee, may rescind and annul such declaration of acceleration and its
consequences if:

(1) the Trust 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 and any Additional Amounts payable in respect of 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 and any Additional Amounts 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.

39
46
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 Trust covenants that if:

(1) default is made in the payment of any
installment of interest or Additional Amounts, if any, on any Security
of any series and any related coupon when such interest or Additional
Amount 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 Trust 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 and Additional Amounts, 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 overdue installments of interest or Additional Amounts, if any, 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 Trust 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 Trust 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 Trust 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 Trust or any other obligor upon the Securities or
the property of the Trust 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

40
47
as therein expressed or by declaration or otherwise and irrespective of whether
the Trustee shall have made any demand on the Trust 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 and Additional Amounts, if any, owing and
unpaid in respect of the Securities and to file such other papers or
documents as may be necessary or advisable in order to have the claims
of the Trustee (including any claim for the reasonable compensation,
expenses, disbursements and advances of the Trustee, its agents and
counsel) and of the Holders allowed in such judicial proceeding, and

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

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

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

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.

41
48
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 and any Additional Amounts, 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 and any Additional Amounts
payable, in respect of which or for the benefit of which such money
has been collected, ratably, without preference or priority of any
kind, according to the aggregate amounts due and payable on such
Securities and coupons for principal (and premium or Make-Whole
Amount, if any), interest and Additional Amounts, respectively; and

THIRD: To the payment of the remainder, if any, to the Trust.

The Trustee may fix a record date and payment date for any payment to
Holders pursuant to this Section 506. At least 15 days before such record
date, the Trustee shall mail to each Holder and the Trust a notice that states
the record date, the payment date and the amount to be paid under this Section
506.

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;

42
49
(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, INTEREST AND ADDITIONAL AMOUNTS.
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, and any Additional Amounts
in respect of, such Security or payment of such coupon on the respective due
dates expressed in such Security or coupon (or, in the case of redemption, on
the Redemption Date) and to institute suit for the enforcement of any such
payment, and such rights shall not be impaired without the consent of such
Holder.

SECTION 509. RESTORATION OF RIGHTS AND REMEDIES. If the Trustee or
any Holder of a Security or coupon has instituted any proceeding to enforce any
right or remedy under this Indenture and such proceeding has been discontinued
or abandoned for any reason, or has been determined adversely to the Trustee or
to such Holder, then and in every such case, the Trust, 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.

43
50
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.

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 or Additional
Amounts payable in respect of 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.

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.

44
51
SECTION 514. WAIVER OF USURY, STAY OR EXTENSION LAWS. The Trust
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 Trust (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 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 or any Additional Amounts with respect to any
Security of such series, or in the payment of any sinking fund installment with
respect to the Securities of such series, the Trustee shall be protected in
withholding such notice if and so long as Responsible Officers of the Trustee
in good faith determine that the withholding of such notice is in the interests
of the Holders of the Securities and coupons of such series; and provided
further that in the case of any default or breach of the character specified in
Section 501(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.

45
52
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 Trust
mentioned herein shall be sufficiently evidenced by a Trust Request or
Trust 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 Trust Managers
may be sufficiently evidenced by a Board Resolution;

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

(4) the Trustee may consult with counsel and the
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

46
53
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 Trust,
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; and

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

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

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

SECTION 603. NOT RESPONSIBLE FOR RECITALS OR ISSUANCE OF SECURITIES.
The recitals contained herein and in the Securities, except the Trustee's
certificate of authentication, and in any coupons shall be taken as the
statements of the Trust, 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, of the
Securities or coupons or of any offering document used in connection with
Securities, 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 Trust 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 Trust, 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 Trust 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 shall be under no liability for interest on any money
received by it hereunder except as otherwise agreed with the Trust.

47
54
SECTION 606. COMPENSATION AND REIMBURSEMENT. The Trust agrees:

(1) to pay to the Trustee from time to time and,
within 30 days of receiving a written request therefor, 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, within 30 days of receiving a written request
therefor, 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, within 30 days of receiving a
written request therefor, 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 Trust 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 a
combined capital and surplus of at least $15,000,000. If such corporation
publishes reports of condition at least annually, pursuant to law or the
requirements of Federal, state, territorial or District of Columbia supervising
or examining authority, then for

48
55
the purposes of this Section, the combined capital and surplus of such
corporation shall be deemed to be its combined capital and surplus as set forth
in its most recent report of condition so published. If at any time the
Trustee 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 Trust nor any Person
directly or indirectly controlling, controlled by, or under common control with
the Trust 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
Trust. 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 Trust.

(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
Trust 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 Trust 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 Trust 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.

49
56
(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 Trust, 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 Trust 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 Trust. If no successor Trustee with respect
to the Securities of any series shall have been so appointed by the Trust 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 Trust 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 Trust 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 Trust
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
Trust, the retiring Trustee and each successor Trustee with respect to the
Securities of one or more series shall execute and deliver an indenture
supplemental hereto, pursuant to Article Nine hereof, wherein each successor
Trustee shall accept

50
57
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 Trust 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 Trust
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 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

51
58
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 Trust. 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 Trust 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 Trust. The Trustee for any series of Securities may at any time
terminate the agency of an Authenticating Agent by giving written notice of
termination to such Authenticating Agent and to the Trust. 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 Trust

52
59
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 Trust 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

(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

53
60
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.

Holder of Securities or coupons, by receiving and holding the same, agrees with
the Trust and the Trustee

54
61
that neither the Trust 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 and addresses of the Holders

AND CONVEYANCES PERMITTED SUBJECT TO CERTAIN CONDITIONS. The Trust 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 Trust 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

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 Trust, 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 Trust, any or all of the Securities issuable

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.

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

65
(10) to supplement any of the provisions of this
Indenture to such extent as shall be necessary to permit or facilitate

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.

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 Trust and the Trustee, the Trust, when authorized

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

Indenture, or reduce the requirements of Section 1504 for quorum or
voting, or

(3) modify any of the provisions of this Section

percentage to effect such action or to provide that certain other
provisions of this Indenture cannot be modified or waived without the

66
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(8).

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

SECTION 1001. PAYMENT OF PRINCIPAL, PREMIUM OR MAKE-WHOLE AMOUNT, IF
ANY; INTEREST AND ADDITIONAL AMOUNTS. The Trust 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 and any Additional Amounts payable in respect of 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 and any Additional Amounts payable in respect of Bearer
Securities on or before Maturity, other than Additional Amounts, if any,
payable as provided in Section 1010 in respect of principal of (or premium or
Make-Whole Amount, if any, on) such a Security, 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 Trust, all payments of principal and interest
may be paid by check to, or by transfer to an account maintained by, the
registered Holder of the Registered Security or other person entitled thereto,
which payments in the case of principal shall be made against surrender of such
Security.

SECTION 1002. MAINTENANCE OF OFFICE OR AGENCY. The Trust 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 Trust in
respect of the Securities of that series and this Indenture may be served. The
Trust 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 Trust 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); and with respect to Bearer
Securities of any series and subject to any laws or regulations applicable
thereto, in a Place of Payment for that series which is located outside the
United States; (B) 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 securities
exchange located outside the United States and such securities exchange shall
so require, the Trust 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) an office or agency where any Bearer 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 Trust
in respect of the Securities of that series and this Indenture may be served.
The Trust 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
Trust shall fail to maintain any

61
68
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 Trust hereby appoints the same as its agent to receive such
respective presentations, surrenders, notices and demands, and the Trust 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 or Additional Amounts in respect of Bearer Securities shall be made at any
office or agency of the Trust 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 (including any Additional
Amounts payable on Securities of such series pursuant to Section 1010) shall be
made at the office of the Trust'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, interest or Additional Amounts,
as the case may be, at all offices or agencies outside the United States
maintained for the purpose by the Trust in accordance with this Indenture, is
illegal or effectively precluded by exchange controls or other similar
restrictions.

The Trust 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 Trust 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 Trust 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 Trust hereby designates as a Place of Payment for each series of Securities
the office or agency of the Trust in the Borough of Manhattan, The City of New
York, and initially appoints the Trustee at its office or agency in such city
as Paying Agent and as its agent to receive all such presentations, surrenders,
notices and demands.

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

SECTION 1003. MONEY FOR SECURITIES PAYMENTS TO BE HELD IN TRUST. If
the Trust shall at any time act as its own Paying Agent with respect to any
series of any Securities and any related

62
69
coupons, it will, on or before each due date of the principal of (and premium
or Make-Whole Amount, if any), or interest on or Additional Amounts in respect
of, 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 or Additional
Amounts 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 Trust 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 or
Additional Amounts in respect of, 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 or Additional Amounts, 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 or Additional Amounts and (unless such
Paying Agent is the Trustee) the Trust will promptly notify the Trustee of its
action or failure so to act.

The Trust 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
Trust (or any other obligor upon the Securities) in the making of any
such payment of principal (and 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 Trust may at any time, for the purpose of obtaining the
satisfaction and discharge of this Indenture or for any other purpose, pay, or
by Trust Order direct any Paying Agent to pay, to the Trustee all sums held in
trust by the Trust 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 Trust 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.

63
70
Except as otherwise provided in the Securities of any series, any
money deposited with the Trustee or any Paying Agent, or then held by the
Trust, in trust for the payment of the principal of (and premium or Make-Whole
Amount, if any) or interest on, or any Additional Amounts in respect of, any
Security of any series and remaining unclaimed for two years after such
principal (and premium or Make-Whole Amount, if any), interest or Additional
Amounts has become due and payable shall be paid to the Trust upon Trust
Request or (if then held by the Trust) shall be discharged from such trust; and
the Holder of such Security shall thereafter, as an unsecured general creditor,
look only to the Trust for payment of such principal of (and premium or
Make-Whole Amount, if any) or interest on, or any Additional Amounts in respect
of, 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
Trust 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 Trust 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 Trust.

SECTION 1004. EXISTENCE. Subject to Article Eight, the Trust 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 Trust shall not be required to preserve any such right or franchise if
the Board of Trust Managers shall determine that the preservation thereof is no
longer desirable in the conduct of the business of the Trust.

SECTION 1005. MAINTENANCE OF PROPERTIES. The Trust will, and will
cause all of its Subsidiaries to, cause all of its and their respective
material properties used or useful in the conduct of its and their respective
businesses to be maintained and kept in good condition, repair and working
order and supplied with all necessary equipment and will cause to be made all
necessary repairs, renewals, replacements, betterments and improvements
thereof, all as in the judgment of the Trust 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 Trust 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 Trust will cause each of its and its
Subsidiaries' insurable properties to be insured against loss or damage in an
amount at least equal to their then full insurable value with insurers of
recognized responsibility.

SECTION 1007. PAYMENT OF TAXES AND OTHER CLAIMS. The Trust 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

64
71
income, profits or property of the Trust 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 Trust or any Subsidiary; provided, however,
that the Trust 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. PROVISION OF FINANCIAL INFORMATION. Whether or not the
Trust is subject to Section 13 or 15(d) of the Securities Exchange Act of 1934,
the Trust will prepare the annual reports, quarterly reports and other
documents within 15 days of each of the respective dates by which the Trust
would have been required to file such annual reports, quarterly reports and
other documents with the Commission pursuant to such Section 13 or 15(d) and
will (i) transmit by mail to all Holders, as their names and addresses appear
in the Security Register, upon written request and without cost to such Holders
copies of the annual reports, quarterly reports and other documents which the
Trust would have been required to file with the Commission pursuant to Section
13 or 15(d) of the Securities Exchange Act of 1934 if the Trust were subject to
such Sections, and (ii) file with the Trustee copies of the annual reports,
quarterly reports and other documents which the Trust would have been required
to file with the Commission pursuant to Section 13 or 15(d) of the Securities
Exchange Act of 1934 if the Trust were subject to such Sections and (iii)
promptly upon written request and payment of the reasonable cost of duplication
and delivery, supply copies of such documents to any prospective Holder.

SECTION 1009. STATEMENT AS TO COMPLIANCE. The Trust 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 Trust'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 1009, such compliance shall be
determined without regard to any period of grace or requirement of notice under
this Indenture.

SECTION 1010. ADDITIONAL AMOUNTS. If any Securities of a series
provide for the payment of Additional Amounts, the Trust will pay to the Holder
of any Security of such series or any coupon appertaining thereto Additional
Amounts as may be specified as contemplated by Section 301. Whenever in this
Indenture there is mentioned, in any context except in the case of Section
502(1), the payment of the principal of or any premium or Make-Whole Amount or
interest on, or in respect of, any Security of any series or payment of any
related coupon or the net proceeds received on the sale or exchange of any
Security of any series, such mention shall be deemed to include mention of the
payment of Additional Amounts provided by the terms of such series established
pursuant to Section 301 to the extent that, in such context, Additional Amounts
are, were or would be payable in respect thereof pursuant to such terms and
express mention of the payment of Additional Amounts (if applicable) in any
provisions hereof shall not be construed as excluding Additional Amounts in
those provisions hereof where such express mention is not made.

65
72
Except as otherwise specified as contemplated by Section 301, if the
Securities of a series provide for the payment of Additional Amounts, at least
10 days prior to the first Interest Payment Date with respect to that series of
Securities (or if the Securities of that series will not bear interest prior to
Maturity, the first day on which a payment of principal and any premium or
Make-Whole Amount is made), and at least 10 days prior to each date of payment
of principal and any premium or Make-Whole Amount or interest if there has been
any change with respect to the matters set forth in the below-mentioned
Officers' Certificate, the Trust will furnish the Trustee and the Trust's
principal Paying Agent or Paying Agents, if other than the Trustee, with an
Officers' Certificate instructing the Trustee and such Paying Agent or Paying
Agents whether such payment of principal of and any premium or Make-Whole
Amount or interest on the Securities of that series shall be made to Holders of
Securities of that series or any related coupons who are not United States
persons without withholding for or on account of any tax, assessment or other
governmental charge described in the Securities of the series. If any such
withholding shall be required, then such Officers' Certificate shall specify by
country the amount, if any, required to be withheld on such payments to such
Holders of Securities of that series or related coupons and the Trust will pay
to the Trustee or such Paying Agent the Additional Amounts required by the
terms of such Securities. In the event that the Trustee or any Paying Agent,
as the case may be, shall not so receive the above-mentioned certificate, then
the Trustee or such Paying Agent shall be entitled (i) to assume that no such
withholding or deduction is required with respect to any payment of principal
or interest with respect to any Securities of a series or related coupons until
it shall have received a certificate advising otherwise and (ii) to make all
payments of principal and interest with respect to the Securities of a series
or related coupons without withholding or deductions until otherwise advised.
The Trust covenants to indemnify the Trustee and any Paying Agent for, and to
hold them harmless against, any loss, liability or expense reasonably incurred
without negligence or bad faith on their part arising out of or in connection
with actions taken or omitted by any of them or in reliance on any Officers'
Certificate furnished pursuant to this Section or in reliance on the Trust's
not furnishing such an Officers' Certificate.

SECTION 1011. WAIVER OF CERTAIN COVENANTS. The Trust may omit in any
particular instance to comply with (1) any term, provision or condition set
forth in Sections 1004 to 1008, inclusive, or (2) any other covenant applicable
to the Securities of any series pursuant to Section 301 which other covenant
(i) does not expressly provide to the contrary and (ii) is not of the kind
which could not be amended without the consent of the Holder of each
Outstanding Security of such series pursuant to Section 902, 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 term, provision, condition or covenant, but no such waiver shall
extend to or affect such term, provision, condition or covenant except to the
extent so expressly waived, and, until such waiver shall become effective, the
obligations of the Trust and the duties of the Trustee in respect of any such
term, provision, condition or covenant shall remain in full force and effect.

ARTICLE ELEVEN - REDEMPTION OF SECURITIES

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

SECTION 1102. ELECTION TO REDEEM; NOTICE TO TRUSTEE. The election of
the Trust to redeem any Securities shall be evidenced by or pursuant to a Board
Resolution. In case of any redemption at the election of the Trust of less
than all of the Securities of any series, the Trust 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 Trust 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 Trust 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.

67
74
Any notice that is mailed to the Holders of Registered Securities in
the manner herein provided shall be conclusively presumed to have been duly
given, whether or not the Holder receives the notice.

All notices of redemption shall state:

(1) the Redemption Date,

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

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

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

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

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

(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 Trust, 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 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 Trust, on which such exchanges may be made,

68
75
(10) the CUSIP number of such Security, if any,
and

(11) that Securities of the series called for
redemption and all unmatured coupons, if any, relating thereto, must
be surrendered to the Paying Agent as a condition of payment of the
Redemption Price.

Notice of redemption of Securities to be redeemed at the election of
the Trust shall be given by the Trust or, at the Trust's written request
provided to the Trustee not less than 45 days nor more than 60 days prior to
the Redemption Date, by the Trustee in the name and at the expense of the
Trust.

SECTION 1105. DEPOSIT OF REDEMPTION PRICE. On or prior to any
Redemption Date, the Trust shall deposit with the Trustee or with a Paying
Agent (or, if the Trust 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.

If any Securities called for redemption are converted, any money
deposited with the Trustee or with any Paying Agent or so segregated and held
in trust for the redemption of such Security shall be paid to the Trust upon
Trust Request or, if then held by the Trust, shall be discharged from such
trust.

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 Trust 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 Trust 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,

69
76
unless otherwise specified as contemplated by Section 301, only upon
presentation and surrender of coupons for such interest; and provided further
that, except as otherwise provided with respect to Securities convertible into
Common Shares or Preferred Shares, installments of interest on Registered
Securities whose Stated Maturity is on or prior to the Redemption Date shall be
payable to the Holders of such Securities, or one or more Predecessor
Securities, registered as such at the close of business on the relevant Record
Dates according to their terms and the provisions of Section 307.

If any Bearer Security surrendered for redemption shall not be
accompanied by all appurtenant coupons maturing after the Redemption Date, such
Security may be paid after deducting from the Redemption Price an amount equal
to the face amount of all such missing coupons, or the surrender of such
missing coupon or coupons may be waived by the Trust 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 Trust or the Trustee so requires, due endorsement by, or
a written instrument of transfer in form satisfactory to the Trust and the
Trustee duly executed by, the Holder thereof or his attorney duly authorized in
writing) and the Trust 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, having the same form, terms and Stated Maturity,
in 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 Trust shall execute and the Trustee shall authenticate and
deliver to the depository, without service charge, a new Global Security having
the same form, terms and Stated Maturity 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

Securities of a series except as otherwise specified as contemplated by Section
301 for Securities of such series.

70
77
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
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 Trust 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 Trust 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
Trust; 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 Trust 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 Trust 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 Trust 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 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 Trust covenants that prior to 11:00 a.m. New York time on
the Repayment Date it will deposit with the Trustee or with a Paying Agent (or,
if the Trust 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 Trust 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

72
79
to the Holder for the portion of the principal amount of such Security
surrendered that is not to be repaid, must be specified. The principal amount
of any Security providing for repayment at the option of the Holder thereof may
not be repaid in part if, following such repayment, the unpaid principal amount
of such Security would be less than the minimum authorized denomination of
Securities of the series of which such Security to be repaid is a part. Except
as otherwise may be provided by the terms of any Security providing for
repayment at the option of the Holder thereof, exercise of the repayment option
by the Holder shall be irrevocable unless waived by the Trust.

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 Trust on the Repayment Date therein specified,
and on and after such Repayment Date (unless the Trust 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 Trust, 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 Trust 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 Trust 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.

73
80
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 Trust shall execute
and the Trustee shall authenticate and deliver to the Holder of such Security,
without service charge and at the expense of the Trust, a new Registered
Security or Securities of the same series, having the same form, terms and
Stated Maturity, in 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; TRUST'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 Trust 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 Trust's exercise of
the above option applicable to this Section with respect to any Securities of
or within a series, the Trust 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 Trust 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 Trust, shall
execute proper instruments acknowledging the same), except for the following
which shall survive until otherwise terminated or discharged hereunder: (A) the
rights of Holders of such Outstanding Securities and any coupons appertaining
thereto to receive, solely from the trust fund

74
81
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 Trust's obligations with respect to such
Securities under Sections 304, 305, 306, 1002 and 1003 and with respect to the
payment of Additional Amounts, if any, on such Securities as contemplated by
Section 1010, (C) the rights, powers, trusts, duties and immunities of the
Trustee hereunder and (D) this Article. Subject to compliance with this
Article Fourteen, the Trust 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 Trust's exercise of the
above option applicable to this Section with respect to any Securities of or
within a series, the Trust shall be released from its obligations under
Sections 1004 to 1008, 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 1008, 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 Trust 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(9) 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 Trust 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) Government Obligations
applicable to such Securities and coupons appertaining thereto (determined on
the basis

75
82
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 Trust 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 shall occur as a result of such
deposit or, insofar as Sections 501(7) and 501(8) 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
Trust shall have delivered to the Trustee an Opinion of Counsel stating that
(i) the Trust 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
Trust shall have delivered to the Trustee an Opinion of Counsel to the effect
that the Holders of such Outstanding Securities and any coupons appertaining
thereto will not recognize income, gain or loss for Federal income tax purposes
as a result of such covenant defeasance and will be subject to Federal income
tax on the same amounts, in the same manner and at the same times as would have
been the case if such covenant defeasance had not occurred.

76
83
(f) The Trust 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 Trust's option
under Section 1402 or Section 1403 (as the case may be), registration is not
required under the Investment Trust Act of 1940, as amended, by the Trust, 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 Trust in connection therewith pursuant to Section 301.

SECTION 1405. DEPOSITED MONEY AND GOVERNMENT OBLIGATIONS TO BE HELD
IN TRUST; OTHER MISCELLANEOUS PROVISIONS. Subject to the provisions of the
last paragraph of Section 1003, all money and Government Obligations (or other
property as may be provided pursuant to Section 301) (including the proceeds
thereof) deposited with the Trustee (or other qualifying trustee, collectively
for purposes of this Section 1405, the "Trustee") pursuant to Section 1404 in
respect of any Outstanding Securities of any series and any coupons
appertaining thereto shall be held in trust and applied by the Trustee, in
accordance with the provisions of such Securities and any coupons appertaining
thereto and this Indenture, to the payment, either directly or through any
Paying Agent (including the Trust 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 and
Additional Amounts, if any, but such money need not be segregated from other
funds except to the extent required by law.

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

77
84
The Trust 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 Trust from time to time
upon Trust 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

coupons, whether or not present or represented at the meeting.

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

for such meeting; and

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.

(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 Trust or by Holders of Securities as provided in Section 1502(b),
in which case the Trust 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;
