form one instrument.

         SECTION 104. Acts of Holders.

                  (a) Any request, demand, authorization, direction, notice,
         consent, waiver or other action provided by this Indenture to be given
         or taken by Holders of the Outstanding Securities of all series or one
         or more series, as the case may be, may be embodied in and evidenced by
         one or more instruments of substantially similar tenor signed by such
         Holders in person or by agents duly appointed in writing. If Securities
         of a series are issuable as Bearer Securities, any request, demand,
         authorization, direction, notice, consent, waiver or other action
         provided by this Indenture to be given or taken by Holders of
         Securities of such series may, alternatively, be embodied in and
         evidenced by the record of Holders of Securities of such series voting
         in favor thereof, whether 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

                                       12
<PAGE>

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

                  (b) The fact and date of the execution by any Person of any
         such instrument or writing may be proved by the affidavit of a witness
         of such execution or by a certificate of a notary public or other
         officer authorized by law to take acknowledgements 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.

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

                  (e) If the Company shall solicit from the Holders of
         Registered Securities any request, demand, authorization, direction,
         notice, consent, waiver or other Act, the Company may, at its option,
         in or pursuant to a Board Resolution, fix in advance a record date for
         the determination of Holders entitled to give such request, demand,
         authorization,

                                       13
<PAGE>

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

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

         SECTION 105. Notices, etc., to Trustee and Company.

         Any request, demand, authorization, direction, notice, consent, waiver
or Act of Holders or other document provided or permitted by this Indenture to
be made upon, given or furnished to, or filed with,

                  (1) the Trustee by any Holder or by the Company shall be
         sufficient for every purpose hereunder if made, given, furnished or
         filed in writing to or with the Trustee at its Corporate Trust Office,
         Attention: Corporate Trust Operations, or

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

         SECTION 106. Notice to Holders; Waiver.

         Where this Indenture provides for notice of any event to Holders of
Registered Securities by the Company or the Trustee, such notice shall be
sufficiently given (unless otherwise herein

                                       14
<PAGE>

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

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

         Except as otherwise expressly provided herein or otherwise qualified
with respect to any Securities pursuant to Section 301, where this Indenture
provides for notice to Holders of Bearer Securities of any event, such notices
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, and if the Securities of such series are listed on any stock
exchange outside the United States, in any place at which such Securities are
listed on a securities exchange to the extent that such securities exchange so
requires, on a Business Day, such publication to be not later than the latest
date, and not earlier than the earliest date, prescribed for the giving of such
notice. Any such notice shall be deemed to have been given on the date of such
publication or, if published more than once, on the date of the first such
publication.

         If by reason of the suspension of publication of any Authorized
Newspaper or Authorized Newspapers or by reason of any other cause it shall be
impracticable to publish any 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

                                       15
<PAGE>

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. Effect of Headings and Table of Contents.

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

         SECTION 108. Successors and Assigns.

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

         SECTION 109. Separability Clause.

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

         SECTION 110. Benefits of Indenture.

         Nothing in this Indenture or in the Securities or coupons appertaining
thereto, 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. No Personal Liability.

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

         SECTION 112. Governing Law.

         This Indenture and the Securities and coupons shall be governed by and
construed in accordance with the law of the Commonwealth of Virginia. 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 113. 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
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) need not be made
at such Place of Payment on such date, but may be made on the next succeeding
Business Day at such Place of Payment with the same force and effect as if made
on the Interest Payment Date, Redemption Date, Repayment Date or sinking fund
payment date, or at the Stated Maturity or Maturity, 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.

                                SECURITIES FORMS

         SECTION 201. Forms of Securities.

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

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

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

         SECTION 202. Form of Trustee's Certificate of Authentication.

         Subject to Section 611, the Trustee's certificate of authentication
shall be in substantially the following form:

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

                                       _____________________________, as
                                       Trustee

                                       By  _____________________________
                                           Authorized Signatory

<PAGE>

         SECTION 203. Securities Issuable in Global Form.

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

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

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

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

         on any Registered Security on any Interest Payment Date, or the method
         by which such date shall be determined, and the basis upon which
         interest shall be calculated if other than that of a 360-day year
         consisting of twelve 30-day months;

         thereof pursuant to Section 502, or the method by which such portion
         shall be determined;

         premium or Make- Whole Amount, if any) or interest, if any, on the
         Securities of or within the series may be determined with reference to
         an index, formula or other method (which index, formula or method may

         Events of Default or covenants of the Company with respect to

         beneficial owners of interests in any such 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 occur, if other than in the manner
         provided in Section 305, and, if Registered Securities of or within the

         issued;

         registered at the close of business on the Regular Record Date for such
         interest, the manner in which, or the Person to whom, any interest on
         any Bearer Security of the series shall be payable, if otherwise than
         upon presentation and surrender of the coupons appertaining thereto as

         to the Securities of or within the series and any provisions in
         modification of, in addition to or in lieu of any of the provisions of
         Article Fourteen;

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

         (including any modification to the definition of such term) in respect
         of any tax, assessment or governmental charge and, if so, whether the
         Company will have the option to redeem such Securities rather than pay
         such Additional Amounts (and the terms of any such option);

                  (23) the obligation, if any, of the Company to permit the
         conversion of the Securities of such series into shares of Capital
         Stock of the Company and the terms and conditions upon which such
         conversion shall be effected (including, without limitation, the
         initial conversion price or rate, the conversion period, any adjustment
         of the applicable conversion price or rate and any requirements
         relative to the reservation of such shares for purposes of conversion);
         and

                  (24) any other terms of the series (which terms shall not be
         inconsistent with the provisions of this Indenture).

         All Securities of any one series and the coupons appertaining to any
Bearer Securities of such series, if any, shall be substantially identical
except, in the case of Registered or Bearer Securities issued in global form, as
to denomination and except as may otherwise be provided in or pursuant to such
Board Resolution 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 or supplemental
indentures, a copy of an appropriate record of such action(s) shall be certified
by the Secretary or an Assistant Secretary of the Company and

                                       23
<PAGE>

delivered to the Trustee at or prior to the delivery of the Company Order for
authentication and delivery of such Securities.

         SECTION 302. Denominations.

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

         SECTION 303. Execution, Authentication Delivery and Dating.

         The Securities and any coupons appertaining thereto shall be executed
on behalf of the Company by its President or a Vice President, under its
corporate seal reproduced thereon, and attested by its Secretary or an Assistant
Secretary. 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 appertaining thereto bearing the manual or
facsimile signatures of individuals who were at any time the proper officers of
the Company shall bind the Company, notwithstanding that such individuals or any
of them have ceased to hold such offices prior to the authentication and
delivery of such Securities or did not hold such offices at the date of such
Securities or coupons.

         At any time and from time to time after the execution and delivery of
this Indenture, the Company may deliver Securities of any series, together with
any coupon appertaining thereto, executed by the Company to the Trustee for
authentication, together with a Company Order for the authentication and
delivery of such Securities, and the Trustee in accordance with the Company
Order shall authenticate and deliver such Securities; provided, however, that,
in connection with its original issuance, no Bearer Security shall be mailed or
otherwise delivered to any location in the United States; and provided further
that, unless otherwise specified with respect to any series of Securities
pursuant to Section 301 a Bearer Security may be delivered in connection with
its original issuance only if the Person entitled to receive such Bearer
Security shall have furnished a certificate to Euroclear or CEDEL, as the case
may be, in the form set forth in Exhibit A-1 to this Indenture or such other
certificate as may be specified with respect to any series of Securities
pursuant to Section 301, dated no earlier than 15 days prior to the earlier of
the date on which such Bearer Security is delivered and the date on which any
temporary Security first becomes exchangeable for such Bearer Security in
accordance with the terms of such temporary Security and this Indenture. Except
as permitted by Section 306, the Trustee

                                       24
<PAGE>

shall not authenticate and deliver any Bearer Security unless all appurtenant
coupons for interest then matured have been detached and cancelled.

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

                  (i) an Opinion of Counsel complying with Section 102 and
         stating that:

                           (a) the form or forms of such Securities and any
                  coupons have been, or will have been upon compliance with such
                  procedures as may be specified therein, established in
                  conformity with the provisions of this Indenture;

                           (b) the terms of such Securities and any coupons have
                  been, or will have been upon compliance with such procedures
                  as may be specified therein, established in conformity with
                  the provisions of this Indenture; and

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

                  (ii) an Officers' Certificate complying with Section 102 and
         stating that all conditions precedent provided for in this Indenture
         relating to the issuance of such Securities have been, or will have
         been upon compliance with such procedures as may be specified therein,
         complied with and that, to the best of the knowledge of the signers of
         such certificate, no Event of Default with respect to such Securities
         shall have occurred and be continuing.

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

                                       25
<PAGE>

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 a Company Order, 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 certificate, 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 appertaining thereto shall be entitled to any
benefit under this Indenture or be valid or obligatory for any purpose unless
there appears on such Security or the 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 officer, and such
certificate upon any Security shall be conclusive evidence, and the only
evidence, that such Security has been duly authenticated and delivered hereunder
and is entitled to the benefits of this Indenture. Notwithstanding the
foregoing, if any Security shall have been authenticated and delivered hereunder
but never issued and sold by the Company, and the Company shall deliver such
Security to the Trustee for cancellation as provided in Section 309 together
with a written statement (which need not comply with Section 102 and need not be
accompanied by an Opinion of Counsel) stating that such Security has never been
issued or sold by the Company, for all purposes of this Indenture such Security
shall be deemed never to have been authenticated and delivered hereunder and
shall never be entitled to the benefits of this Indenture.

         SECTION 304. Temporary Securities.

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

                  Except in the case of temporary Securities in global form
         (which shall be exchanged in accordance with Section 304(b) or as
         otherwise provided in or pursuant to a Board Resolution), if temporary
         Securities of any series are issued, the Company will cause definitive
         Securities of that series to be prepared without unreasonable delay.
         After the

                                       26
<PAGE>

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

                  (b) Unless otherwise provided as contemplated in Section 301,
         this Section 304(b) shall govern the exchange of temporary Securities
         issued in global form other than through the facilities of DTC. If any
         such temporary Security is issued in global form, then such temporary
         global Security shall, unless otherwise provided therein, be delivered
         to the London office of a depositary or common depositary (the "Common
         Depositary"), for the benefit of Euroclear and CEDEL.

         Without unnecessary delay but in any event not later than the date
specified in, or determined pursuant to the terms of, any such temporary global
Security (the "Exchange Date"), the Company shall deliver to the Trustee
definitive Securities, in an aggregate principal amount equal to the principal
amount of such temporary global Security, executed by the Company. On or after
the Exchange Date, such temporary global Security shall be surrendered by the
Common Depositary to the Trustee, as the Company's agent for such purpose, to be
exchanged, in whole or from time to time in part, for definitive Securities
without charge, and the Trustee shall authenticate and deliver, in exchange for
each portion of such temporary global Security, an equal aggregate principal
amount of definitive Securities of or within the same series of authorized
denominations and of like tenor as the portion of such temporary global Security
to be exchanged. The definitive Securities to be delivered in exchange for any
such temporary global Security shall be in bearer form, registered form,
permanent global bearer form or permanent global registered form, or any
combination thereof, as specified as contemplated by Section 301, and, if any
combination thereof is so specified, as requested by the beneficial owner
thereof, provided, however, that, unless otherwise specified in such temporary
global Security, upon such presentation by the Common Depositary, such temporary
global Security is accompanied by a certificate dated the Exchange Date or a
subsequent date and signed by Euroclear as to the portion of such temporary
global Security held for its account then to be exchanged and a certificate
dated the Exchange Date or a subsequent date and signed by CEDEL as to the
portion of such temporary global Security held for its account then to be
exchanged, each in the form set forth in Exhibit A-2 to this Indenture or in
such other form as may be established pursuant to Section 301; and provided
further that definitive Bearer Securities shall

                                       27
<PAGE>

be delivered in exchange for a portion of a temporary global Security only in
compliance with the requirements of Section 303.

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

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

                                       28
<PAGE>

returned to the Trustee prior to the expiration of two years after such Interest
Payment Date in order to be repaid to the Company.

         SECTION 305. Registration, Registration of Transfer and Exchange.

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

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

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

         If (but only if) permitted as contemplated by Section 301, at the
option of the Holder, Bearer Securities of any series may be exchanged for
Registered Securities of the same series of any authorized denominations and of
a like aggregate principal amount and tenor, upon surrender of the Bearer
Securities to be exchanged at any such office or agency, with all unmatured
coupons and all matured coupons in default thereto appertaining. If the Holder
of a Bearer Security is unable to produce any such unmatured coupon or coupons
or matured coupon or coupons in default, any such permitted exchange may be
effected if the Bearer Securities are accompanied by payment in funds acceptable
to the Company in an amount equal to the face amount of such missing coupon or
coupons, or the surrender of such missing coupon

                                       29
<PAGE>

or coupons may be waived by the Company and the Trustee if there is furnished to
them such security or indemnity as they may require to save each of them and any
Paying Agent harmless. If thereafter the Holder of such Security shall surrender
to any Paying Agent any such missing coupon in respect of which such a payment
shall have been made, such Holder shall be entitled to receive the amount of
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 Company shall execute, and the Trustee shall
authenticate and deliver, the Securities which the holder making the exchange is
entitled to receive.

         Notwithstanding the foregoing, except as otherwise specified as
contemplated by Section 301, any permanent global Security shall be exchangeable
only as provided in this paragraph. If the depositary for any permanent global
Security is DTC, then, unless the terms of such global Security expressly permit
such global Security to be exchanged in whole or in part for definitive
Securities, a global Security may be transferred, in whole but not in part, only
to a nominee of DTC, or by a nominee of DTC to DTC, or to a successor to DTC for
such global Security selected and approved by the Company or to a nominee of
such successor to DTC. If at any time DTC notifies the Company that it is
unwilling or unable to continue as depositary for the applicable global Security
or Securities or if at any time DTC ceases to be a clearing agency registered
under the Exchange Act if so required by applicable law or regulation, the
Company shall appoint a successor depositary with respect to such global
Security or Securities. If (x) a successor depositary for such global Security
or Securities is not appointed by the Company within 90 days after the Company
receives such notice or becomes aware of such unwillingness, inability or
ineligibility, (y) an Event of Default has occurred and is continuing and the
beneficial owners representing a majority in principal amount of the applicable
series of Securities represented by such global Security or Securities advise
DTC to cease acting as depositary for such global Security or Securities or (z)
the Company, in its sole discretion, determines at any time that all Outstanding
Securities (but not less than all) Securities 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 (provided, however, the Company may not make
such determination during the 40-day restricted period provided by Regulation S
under the Securities Act or during any other similar period during which the
Securities must be held in global form as may be required by the

                                       30

Securities Act), then the Company shall execute, and the Trustee shall
authenticate and deliver definitive Securities of like series, rank, tenor and
terms in definitive form in an aggregate principal amount equal to the principal
amount of such global Security or Securities. If any beneficial owner of an
interest in a permanent global Security is otherwise entitled to exchange such
interest for Securities of such series and of like tenor and principal amount of
another authorized form and denomination, as specified as contemplated by
Section 301 and provided that any applicable notice provided in the permanent
global Security shall have been given, then without unnecessary delay but in any
event not later than the earliest date on which such interest may be so
exchanged, the Company shall execute, and the Trustee shall authenticate and
deliver definitive Securities in aggregate principal amount equal to the
principal amount of such beneficial owner's interest in such permanent global
Security. On or after the earliest date on which such interests may be so
exchanged, such permanent global Security shall be surrendered for exchange by
DTC or such other depositary as shall be specified in the Company Order with
respect thereto to the Trustee, as the Company's agent for such purpose;
provided, however, that no such exchanges may occur during a period beginning at
the opening of business 15 days before any selection of Securities to be
redeemed and ending on the relevant Redemption Date if the Security for which
exchange is requested may be among those selected for redemption; and provided
further that no Bearer Security delivered in exchange for a portion of a
permanent global Security shall be mailed or otherwise delivered to any location
in the United States. If a Registered Security is issued in exchange for any
portion of a permanent global Security after the close of business at the office
or agency where such exchange occurs on (i) any Regular Record Date and before
the opening of business at such office or agency on the relevant Interest
Payment Date, or (ii) any Special Record Date and the opening of business at
such office or agency on the related proposed date for payment of Defaulted
Interest, interest or Defaulted Interest, as the case may be, will not be
payable on such Interest Payment Date or proposed date for payment, as the case
may be, in respect of such Registered Security, but will be payable on such
Interest Payment Date or proposed date for payment, as the case may be, only to
the Person to whom interest in respect of such portion of such permanent global
Security is payable in accordance with the provisions of this Indenture.

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

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

         No service charge shall be made for any registration of transfer or
exchange of Securities, but the Company may require payment of a sum sufficient
to cover any tax or other governmental charge that may be imposed in connection
with any registration of transfer or

                                       31
<PAGE>

exchange of Securities, other than exchanges pursuant to Section 304, 906, 1107
or 1305 not involving any transfer.

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

         SECTION 306. Mutilated, Destroyed, Lost and Stolen Securities.

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

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

                                       32
<PAGE>

         Notwithstanding the provisions of the previous two paragraphs, in case
any such mutilated, destroyed, lost or stolen Security or coupon has become or
is about to become due and payable, the Company in its discretion may, instead
of issuing a new Security, with coupons corresponding to the coupons, if any,
appertaining to such destroyed, lost or stolen Security or to the Security to
which such destroyed, lost or stolen coupon appertains, pay such Security or
coupon; provided, however, that payment of principal of (and premium or
Make-Whole Amount, if any), 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 Company
may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation thereto and any other
expenses (including the fees and expenses of the Trustee) connected therewith.

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

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

         SECTION 307. Payment of Interest; Interest Rights Preserved.

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

                                       33
<PAGE>

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

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

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

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

                  (1) The Company may elect to make payment of any Defaulted
         Interest to the Persons in whose names the Registered Securities of
         such series (or their respective Predecessor Securities) are registered
         at the close of business on a Special Record Date for the payment of
         such Defaulted Interest, which shall be fixed in the following manner.
         The Company shall notify the Trustee in writing of the amount of
         Defaulted Interest proposed to be paid on each Registered Security of
         such series and the date of the proposed payment (which shall not be
         less than 20 days after such notice is received by the Trustee), and at
         the same time the Company shall deposit with the Trustee an amount of
         money in the currency or currencies, currency unit or units or
         composite currency or currencies in which the Securities of such series
         are payable (except as otherwise specified pursuant to Section 301 for
         the Securities of such series) equal to the aggregate amount proposed
         to be paid in respect of such Defaulted Interest or shall make
         arrangements satisfactory to the Trustee for such deposit on or prior
         to the date of the proposed payment, such money when deposited to be
         held in trust for the benefit of the Persons entitled to such Defaulted
         Interest as in this clause provided. Thereupon the Trustee shall fix a
         Special Record Date for the payment of such Defaulted Interest which
         shall be not more than 15 days and not less than 10 days prior to the
         date of the proposed

                                       34
<PAGE>

         payment and not less than 10 days after the receipt by the Trustee of
         the notice of the proposed payment. The Trustee shall promptly notify
         the Company of such Special Record Date and, in the name and at the
         expense of the Company, shall cause notice of the proposed payment of
         such Defaulted Interest and the Special Record Date therefor to be
         mailed, first-class postage prepaid, to each Holder of Registered
         Securities of such series at his address as it appears in the Security
         Register not less than 10 days prior to such Special Record Date. The
         Trustee may, in its discretion, in the name and at the expense of the
         Company, cause a similar notice to be published at least once in an
         Authorized Newspaper in each place of payment, but such publications
         shall not be a condition precedent to the establishment of such Special
         Record Date. Notice of the proposed payment of such Defaulted Interest
         and the Special Record Date therefor having been mailed as aforesaid,
         such Defaulted Interest shall be paid to the Persons in whose names the
         Registered Securities of such series (or their respective Predecessor
         Securities) are registered at the close of business on such Special
         Record Date and shall no longer be payable pursuant to the following
         clause (2). In case a Bearer Security of any series is surrendered at
         the office or agency in a Place of Payment for such series in exchange
         for a Registered Security of such series after the close of business at
         such office or agency on any Special Record Date and before the opening
         of business at such office or agency on the related proposed date for
         payment of Defaulted Interest, such Bearer Security shall be
         surrendered without the coupon relating to such proposed date of
         payment and Defaulted Interest will not be payable on such proposed
         date of payment in respect of the Registered Security issued in
         exchange for such Bearer Security, but will be payable only to the
         Holder of such coupon when due in accordance with the provisions of
         this Indenture.

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

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

         SECTION 308. Persons Deemed Owners.

         Prior to due presentment of a Registered Security for registration of
transfer, the Company, the Trustee and any agent of the Company or the Trustee
may treat the Person in whose name such Registered Security is registered as the
owner of such Security for the purpose of receiving payment of principal of (and
premium or Make-Whole Amount, if any), and (subject to Sections 305 and 307)
interest on, such Registered Security and for all other purposes whatsoever,

                                       35
<PAGE>

whether or not such Registered Security be overdue, and neither the Company, the
Trustee nor any agent of the Company or the Trustee shall be affected by notice
to the contrary.

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

         None of the Company, the Trustee, any Paying Agent or the Security
Registrar will have any responsibility or liability for any aspect of the
records relating to or payments made on account of beneficial ownership
interests of a Security in global form or for maintaining, supervising or
reviewing any records relating to such beneficial ownership interests.

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

         SECTION 309. Cancellation.

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

         SECTION 310. Computation of Interest.

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

                           SATISFACTION AND DISCHARGE

         SECTION 401.  Satisfaction and Discharge of Indenture.

         This Indenture shall upon Company Request cease to be of further effect
with respect to any series of Securities specified in such Company Request
(except as to any surviving rights of registration of transfer or exchange of
Securities of such series herein expressly provided for and any right to receive
Additional Amounts, as provided in Section 1011), and the Trustee, upon receipt
of a Company Order, and at the expense of the Company, shall execute proper
instruments acknowledging satisfaction and discharge of this Indenture as to
such series when

                  authenticated and delivered and all coupons, if any,
                  appertaining thereto (other than (i) coupons appertaining to
                  Bearer Securities surrendered for exchange for Registered
                  Securities and maturing after such exchange, whose surrender
                  is not required or has been waived as provided in Section 305,

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

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

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

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

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

         SECTION 402. Application of Company 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

         SECTION 501. Events of Default.

         Subject to any modifications, additions or deletions relating to any
series of Securities as contemplated pursuant to Section 301, "Event of
Default," wherever used herein with respect to any particular series of
Securities, means any one of the following events (whatever the reason for such
Event of Default and whether or not it shall be voluntary or involuntary or be
effected by operation of law or pursuant to any judgment, decree or order of any
court or any order, rule or regulation of any administrative or governmental
body):

                  (1) default in the payment of any interest upon or any
         Additional Amounts payable in respect of any Security of or within 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 due and
         payable at its Maturity; or

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

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

         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

         money borrowed by the Company (or by any Subsidiary, the repayment of
         which the Company has guaranteed or for which the Company is directly
         responsible or liable as obligor or guarantor), having an aggregate
         principal amount outstanding of at least $10,000,000, whether such
         indebtedness now exists or shall hereafter be created, which default
         shall have resulted in such indebtedness being declared due and payable
         prior to the date on which it would otherwise have become due and
         payable, without such indebtedness having been discharged, or such
         acceleration having been rescinded or annulled, within a period of 10
         days after there shall have been

                                       39
<PAGE>

         given, by registered or certified mail, to the Company by the Trustee
         or to the Company and the Trustee by the Holders of at least 10% in
         principal amount of the Outstanding Securities of that series a written
         notice specifying such default and requiring the Company to cause such
         indebtedness to be discharged or cause such acceleration to be
         rescinded or annulled and stating that such notice is a "Notice of
         Default" hereunder; or

                  (6) the entry by a court of competent jurisdiction of one 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

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

                           (A) commences a voluntary case,

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

                           (C) consents to the appointment of a Custodian of it

                           (A) is for relief against the Company or any

                           (B) appoints a Custodian of the Company or any

                  Significant Subsidiary

         and the order or decree remains unstayed and in effect for 90 days; or

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

         SECTION 502. Acceleration of Maturity; Rescission and Annulment.

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

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

                  (1) The Company has paid or deposited with the Trustee a sum
         sufficient to pay in the currency, currency unit or composite currency
         in which the Securities of such series is 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

                                       41
<PAGE>

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

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

         SECTION 503. Collection of Indebtedness and Suits for Enforcement by
Trustee.

         The Company covenants that if:

                  (1) default is made in the payment of any installment of
         interest 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 Company will, upon demand of the Trustee, pay to the Trustee, for the
benefit of the Holders of such Securities of such series and coupons, the whole
amount then due and payable on such Securities and coupons for principal (and
premium or Make-Whole Amount, if any) and interest and Additional Amount, 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 Company fails to pay such amounts forthwith upon such demand,
the Trustee, in its own name and as trustee of an express trust, may institute a
judicial proceeding for the collection of the sums so due and unpaid, and may
prosecute such proceeding to judgment or final decree, and may enforce the same
against the Company or any other obligor upon such Securities of such series and
collect the moneys adjudged or decreed to be payable in the manner provided by
law out of the property of the Company or any other obligor upon such Securities
of such series, wherever situated.

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

         SECTION 504. Trustee May File Proofs of Claim.

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

                  (i) to file and prove a claim for the whole amount, or such
         lesser amount as may be provided for in the Securities of such series,
         of principal (and premium or Make- Whole Amount, if any) and interest
         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 allotted in such judicial proceeding, and

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

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

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

         SECTION 505. Trustee May Enforce Claims Without Possession of
Securities or Coupons.

         All rights of action and claims under this Indenture or any of the
Securities or coupons may be prosecuted and enforced by the Trustee without the
possession of any of the Securities or 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,

                                       43
<PAGE>

expenses, disbursements and advances of the Trustee, its agents and counsel, be
for the ratable benefit of the Holders of the Securities and coupons in respect
of which such judgment has been recovered.

         SECTION 506. Application of Money Collected.

         Any money collected by the Trustee pursuant to this Article shall be
applied in the following order, at the date or dates fixed by the Trustee and,
in case of the distribution of such money on account of principal (or premium or
Make-Whole Amount, if any) or interest 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
         Company.

         SECTION 507. Limitation on Suits.

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

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

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

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

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

                                       44
<PAGE>

                  (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 Company, the Trustee and the Holders of Securities and coupons shall,
subject to any determination in such proceeding, be restored severally and
respectively to their former positions hereunder and thereafter all rights and
remedies of the Trustee and the Holders shall continue as though no such
proceeding had been instituted.

         SECTION 510. Rights and Remedies Cumulative.

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

                                       45
<PAGE>

         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 front 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 Companyee 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 (but the Trustee shall
         have no obligation as to the determination of such undue prejudice).

         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

                                       46
<PAGE>

waiver shall extend to any subsequent or other default or Event of Default or
impair any right consequent thereon.

         SECTION 514. Waiver of Usury, Stay or Extension Laws.

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

         SECTION 515. Undertaking for Costs.

         All parties to this Indenture agree, and each Holder of any Security by
his acceptance thereof shall be deemed to have agreed, that any court may in its
discretion require, in any suit for the enforcement of any right or remedy under
this Indenture, or in any suit against the Trustee for any action taken or
omitted by it as Trustee, the filing by any party litigant in such suit of any
undertaking to pay the costs of such suit, and that such court may in its
discretion assess reasonable costs, including reasonable attorneys' fees,
against any party litigant in such suit having due regard to the merits and good
faith of the claims or defenses made by such party litigant; but the provisions
of this Section shall not apply to any suit instituted by the Trustee, to any
suit instituted by any Holder, or group of Holders, holding in the aggregate
more than 10% in principal amount of the Outstanding Securities, or to any suit
instituted by any Holder for the enforcement of the payment of the principal of
(or premium or Make-Whole Amount, if any) or interest on or Additional Amounts
payable with respect to 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).

                                   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

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

         SECTION 602. Certain Rights of Trustee.

         Subject to the provisions of TIA Section 315(a) through 315(d):

         provided therein) and any resolution of the Board of Directors may be
         sufficiently evidenced by a Board Resolution;

                  (4) 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

                                       48
<PAGE>

         action hereunder, the Trustee (unless other evidence be herein

         rely upon an Officers' Certificate;

                  (5) the Trustee may consult with counsel and as a condition to
         the taking, suffering or omission of any action hereunder may demand an
         Opinion of Counsel, and the advice of such counsel or any Opinion of
         Counsel shall be full and complete authorization and protection in
         respect of any action taken, suffered or omitted by it hereunder in
         good faith and in reliance thereon;

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

                  (7) the Trustee shall not be bound to make any investigation

         statement, instrument, opinion, report, notice, request, direction,
         consent, order, bond, debenture, note, coupon or other paper or
         document, but the Trustee, in its discretion, may make such further
         inquiry or investigation into such facts or matters as it may see fit,
         and, if the Trustee shall determine to make such further inquiry or
         investigation, it shall be entitled to examine the books, records and
         premises of the Company, personally or by agent or attorney;

                  (8) the Trustee may execute any of the trusts or powers

         for any misconduct or negligence on the part of any agent or attorney
         appointed with due care by it hereunder; and

                  (9) 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.

         SECTION 603. Not Responsible for Recitals or Issuance of Securities.

         The recitals contained herein and in the Securities, except the

representations as to the validity or sufficiency of this Indenture or of the

                                       49

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

         SECTION 605. Money Held in Trust.

         Money held by the Trustee in trust hereunder need not be segregated

under no liability for interest on, or investment of, any money received by it
hereunder.

         SECTION 606. Compensation and Reimbursement.

         The Company agrees:

                  (1) to pay to the Trustee from time to time reasonable
         compensation for all services rendered by it hereunder, including
         extraordinary services rendered in connection with or during the

         trustee of an express trust);

                  (2) except as otherwise expressly provided herein, to

         Indenture (including the reasonable compensation and the expenses and
         disbursements of its agents and counsel), except to the extent any such

         Trustee for, and to hold it harmless against, any loss, liability or
         expense, arising out of or in connection with the acceptance or
         administration of the trust or trusts or the performance of its duties
         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 except to the extent any such
         loss, liability or expense may be attributable to its own negligence or
         bad faith.

                                       50
<PAGE>

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

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

and surplus of at least $25,000,000. If such corporation publishes reports of
condition at least annually, pursuant to law or the requirements of Federal,
State, Territorial or District of Columbia supervising or examining authority,
then for the purposes of this Section, the combined capital and surplus of such
corporation shall be deemed to be its combined capital and surplus as set forth
in its most recent report of condition so published. If at any time the Trustee
shall cease to be eligible in accordance with the provisions of this Section, it
shall resign immediately in the manner and with the effect hereinafter specified
in this Article.

         SECTION 608. Resignation and Removal; Appointment of Successor.

                  (a) No resignation or removal of the Trustee and no
         appointment of a successor Trustee pursuant to this Article shall

         Trustee in accordance with the applicable requirements of Section 609.

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

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

                  (d) If at any time:

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

                           (2) the Trustee shall cease to be eligible under
                  Section 607(a) and shall fail to resign after written request
                  therefor by the Company or by any Holder of a

                                       51
<PAGE>

                  Security who has been a bona fide Holder of a Security for at
                  least six months, or

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

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

                  (e) If the Trustee shall resign, be removed or become
         incapable of acting, or if a vacancy shall occur in the office of
         Trustee for any cause with respect to the Securities of one or more
         series, the Company, by or pursuant to a Board Resolution, shall
         promptly appoint a successor Trustee or Trustees with respect to the
         Securities of that or those series (it being understood that any such
         successor Trustee may be appointed with respect to the Securities of
         one or more or all of such series and that at any time there shall be
         only one Trustee with respect to the Securities of any particular
         series). If, within one year after such resignation, removal or
         incapability, or the occurrence of such vacancy, a successor Trustee
         with respect to the Securities of any series shall be appointed by Act
         of the Holders of a majority in principal amount of the Outstanding
         Securities of such series delivered to the Company and the retiring
         Trustee, the successor Trustee so appointed shall, forthwith upon its
         acceptance of such appointment, become the successor Trustee with
         respect to the Securities of such series and to that extent supersede
         the successor Trustee appointed by the Company.If no successor Trustee
         with respect to the Securities of any series shall have been so
         appointed by the 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 Company shall give notice of each resignation and each
         removal of the Trustee with respect to the Securities of any series and
         each appointment of a successor Trustee with respect to the Securities
         of any series in the manner provided for notices to the Holders of
         Securities in Section 106. Each notice shall include the name of the
         successor Trustee with respect to the Securities of such series and the
         address of its Corporate Trust Office.

         SECTION 609. Acceptance of Appointment By Successor.

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

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

                                       53
<PAGE>

                  (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,
         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 or that of its predecessor Trustee, with the full force and
effect which this Indenture provides for the certificate of authentication of
the Trustee.

         SECTION 611. Appointment of Authenticating Agent.

         At any time when any of the Securities remain Outstanding, the Trustee
may appoint an Authenticating Agent or Agents with respect to one or more series
of Securities which shall be authorized to act on behalf of the Trustee to
authenticate Securities of such series issued upon exchange, registration of
transfer or partial redemption or repayment thereof, and Securities so
authenticated shall be entitled to the benefits of this Indenture and shall be
valid and obligatory for all purposes as if authenticated by the Trustee
hereunder. Any such appointment shall be evidenced by an instrument in writing
signed by a Responsible Officer of the Trustee, a copy of which instrument shall
be promptly furnished to the Company.Wherever reference is made in this
Indenture to the authentication and delivery of Securities by the Trustee or the
Trustee's certificate of authentication, such reference shall be deemed to
include authentication and delivery on behalf of the Trustee by an
Authenticating Agent and a certificate of authentication executed on behalf of
the Trustee by an Authenticating Agent. Each Authenticating Agent shall be
acceptable to the Trust and, except as may otherwise be provided pursuant to
Section 301, 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 $25,000,000 and subject to supervision or examination by

                                       54
<PAGE>

Federal or State authorities. If such Authenticating Agent publishes reports of
condition at least annually, pursuant to law or the requirements of the
aforesaid supervising or examining authority, then for the purposes of this
Section, the combined capital and surplus of such Authenticating Agent shall be
deemed to be its combined capital and surplus as set forth in its most recent
report of condition so published. In case at any time an Authenticating Agent
shall cease to be eligible in accordance with the provisions of this Section,
such Authenticating Agent shall resign immediately in the manner and with the
effect specified in this Section.

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

         An Authenticating Agent for any series of Securities may at any time
resign by giving written notice of resignation to the Trustee for such series
and to the Company. The Trustee for any series of Securities may at any time
terminate the agency of an Authenticating Agent by giving written notice of
termination to such Authenticating Agent and to the Company. Upon receiving such
a notice of resignation or upon such a termination, or in case at any time such
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, the Trustee for such series may appoint a successor
Authenticating Agent which shall be acceptable to the Company and shall give
notice of such appointment to all Holders of Securities of or within the series
with respect to which such Authenticating Agent will serve in the manner set
forth in Section 106. Any successor Authenticating Agent upon acceptance of its
appointment hereunder shall become vested with all the rights, powers and duties
of its predecessor hereunder, with like effect as if originally named as an
Authenticating Agent herein. No successor Authenticating Agent shall be
appointed unless eligible under the provisions of this Section.

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

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

                                       55
<PAGE>

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

                CONSOLIDATION, MERGER, SALE, LEASE OR CONVEYANCE

         SECTION 801. Consolidations and Mergers of Company and Sales, Leases
and Conveyances Permitted Subject to Certain Conditions.

         The Company may consolidate with, or sell, lease or convey all or
substantially all of its assets to, or merge with or into any other Person,
provided that in any such case, (i) either the Company shall be the continuing
entity, or the successor (if other than the Company) entity shall be a Person
organized and existing under the laws of the United States or a State thereof
and such successor entity shall expressly assume the due and punctual payment of
the principal of (and premium or Make-Whole Amount, if any) and any interest
(including all Additional Amounts, if any, payable pursuant to Section 1011) on
all of the Securities, according to their tenor, and the due and punctual
performance and observance of all of the covenants and conditions of this
Indenture to be performed by the Company by supplemental indenture, complying
with Article Nine hereof, satisfactory to the Trustee, executed and delivered to
the Trustee by such Person and (ii) immediately after giving effect to such
transaction and treating any indebtedness which becomes an obligation of the
Company or any Subsidiary as a result thereof as having been incurred by the
Trust or such Subsidiary at the time of such transaction, no Event of Default,
and no event which, after notice or the lapse of time, or both, would become an
Event of Default, shall have occurred and be continuing.

         SECTION 802. Rights and Duties of Successor Corporation.

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

                                       58
<PAGE>

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

         SECTION 803. Officers' Certificate and Opinion of Counsel.

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

                             SUPPLEMENTAL INDENTURES

         SECTION 901. Supplemental Indentures Without Consent of Holders.

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

                  (1) to evidence the succession of another Person to the Trust
         and the assumption by any such successor of the covenants of the Trust
         herein and in the Securities contained; or

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

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

                  (4) to add to or change any of the provisions of this
         Indenture to provide that Bearer Securities may be registrable as to
         principal, to change or eliminate any restrictions on the payment of
         principal of or any premium, Make-Whole Amount or interest on Bearer
         Securities, to permit Bearer Securities to be issued in exchange for
         Registered Securities, to permit Bearer Securities to be issued in
         exchange for Bearer Securities of other authorized denominations or to
         permit or facilitate the issuance of Securities in uncertificated form,
         provided that any such action shall not adversely affect the interests
         of the Holders of Securities of any series or any related coupons in
         any material respect; or

                                       60
<PAGE>

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

                  (6) to secure the Securities; or

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

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

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

                  (10) to close this Indenture with respect to the
         authentication and delivery of additional series of Securities or to
         qualify, or maintain qualification of, this Indenture under the TIA; or

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

         SECTION 902. Supplemental Indentures with Consent of Holders.

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

                                       61
<PAGE>

                  (1) change the Stated Maturity of the principal of (or premium
         or Make-Whole Amount, if any, on) or any installment of principal of or
         interest on, any Security; or reduce the principal amount thereof or
         the rate or amount of interest thereon or any Additional Amounts
         payable in respect thereof, or any premium or Make-Whole Amount payable
         upon the redemption thereof, or change any obligation of the Company to
         pay Additional Amounts pursuant to Section 1011 (except as contemplated
         by Section 801(1) and permitted by Section 901(1)), or reduce the
         amount of the principal of an Original Issue Discount Security or
         Make-Whole Amount, if any, that would be due and payable upon a
         declaration of acceleration of the Maturity thereof pursuant to Section
         502 or the amount thereof provable in bankruptcy pursuant to Section
         504; or adversely affect any right of repayment at the option of the
         Holder of any Security, or change any Place of Payment where, or the
         currency or currencies, currency unit or units or composite currency or
         currencies in which, the principal of any Security or any premium or
         Make- Whole Amount or any Additional Amounts payable in respect thereof
         or the interest thereon is payable; or impair the right to institute
         suit for the enforcement of any such payment on or after the Stated
         Maturity thereof (or, in the case of redemption or repayment at the
         option of the Holder, on or after the Redemption Date or the Repayment
         Date, as the case may be); or

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

         Holder of each Outstanding Security affected thereby.

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

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

         In executing, or accepting the additional trusts created by, any
supplemental indenture permitted by this Article or the modification thereby of
the trusts created by this Indenture, the Trustee shall be entitled to receive,
and shall be fully protected in relying upon, an Opinion of Counsel stating that
the execution of such supplemental indenture is authorized or permitted by this
Indenture and that all conditions precedent to the execution of such
supplemental indenture have been complied with. The Trustee may, but shall not

Trustees own rights, duties or immunities under this Indenture or otherwise.

         SECTION 904. Effect of Supplemental Indentures.

         Upon the execution of any supplemental indenture under this Article,

         SECTION 1001. Payment of Principal, Premium or Make-Whole Amount, if
any, Interest and Additional Amounts.

         The Company covenants and agrees for the benefit of the Holders of each
series of Securities that it will duly and punctually pay the principal of (and
premium or Make-Whole Amount, if any) and interest on 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 1011 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 Company, all payments of principal may be paid
by check to the registered Holder of the Registered Security or other person
entitled thereto against surrender of such Security.

         SECTION 1002. Maintenance of Office or Agency.

         If Securities of a series are issuable only as Registered Securities,
the Company shall maintain in each Place of Payment for any series of Securities
an office or agency where Securities of that series may be presented or
surrendered for payment, where Securities of that series may be surrendered for
registration of transfer or exchange and where notices and demands to or upon
the Company in respect of the Securities of that series and this Indenture may
be served. If Securities of a series are issuable as Bearer Securities, the
Company will maintain: (A) in the Borough of Manhattan, The City of New York, an
office or agency where any Registered Securities of that series may be presented
or surrendered for payment, where any Registered Securities of that series may
be surrendered for exchange, where notices and demands to or upon the Company in
respect of the Securities of that series and this Indenture may be served and
where Bearer Securities of that series and related coupons may be presented or
surrendered for payment in the circumstances described in the following
paragraph (and not otherwise); (B) subject to any laws or regulations applicable
thereto, in a Place of Payment for that series which is located outside the
United States, an office or agency where Securities of that series and related
coupons may be presented and surrendered for payment (including payment of any
Additional Amounts payable on Securities of that series pursuant to Section
1011); provided, however, that if the Securities of that series are listed on
the Luxembourg Stock Exchange, The International Stock Exchange or any other
stock exchange located outside the United States and such stock exchange shall
so require, the Company will maintain a Paying Agent for the Securities of that
series in Luxembourg, London or any other required city located outside the
United States, as the case

                                       64
<PAGE>

may be, so long as the Securities of that series are listed in such exchange;
and (C) subject to any laws or regulations applicable thereto, in a Place of
Payment for that series located outside the United States an office or agency
where any Securities of that series may be surrendered for registration of
transfer, where Securities of that series may be surrendered for exchange and
where notices and demands to or upon the Company in respect of the Securities of
that series and this Indenture may be served. The Company will give prompt
written notice to the Trustee of the location, and any change in the location,
of each such office or agency. If at any time the Company shall fail to maintain
any such required office or agency or shall fail to furnish the Trustee with the
address thereof, such presentations, surrenders, notices and demands may be made
or served at the Corporate Trust Office of the Trustee, except that Bearer
Securities of that series and the related coupons may be presented and
surrendered for payment (including payment of any Additional Amounts payable on
Bearer Securities of that series pursuant to Section 1011) at the offices
specified in the Security, in London, England, and the Company hereby appoints
the same as its agent to receive such respective presentations, surrenders,
notices and demands, and the Company hereby appoints the Trustee its agent to
receive all such presentations, surrenders, notices and demands.

         Unless otherwise specified with respect to any Securities pursuant to
Section 301, no payment of principal, premium, Make-Whole Amount or interest on
or Additional Amounts in respect of Bearer Securities shall be made at any
office or agency of the Company in the United States or by check mailed to any
address in the United States or by transfer to an account maintained with a bank
located in the United States; provided, however, that, if the Securities of a
series are payable in Dollars, payment of principal of and any premium and
interest on any Bearer Security (including any Additional Amounts or Make-Whole
Amount payable on Securities of such series pursuant to Section 1011) shall be
made at the office of the Company's Paying Agent in the Borough of Manhattan,
The City of New York, if (but only if) payment in Dollars of the full amount of
such principal, premium, interest, Additional Amounts or Make- Whole Amount, as
the case may be, at all offices or agencies outside the United States maintained
for the purpose by the Company in accordance with this Indenture, is illegal or
effectively precluded by exchange controls or other similar restrictions.

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

and ____________________________ as Paying Agent in the Borough of Manhattan,
The City of New York, and appoints each as its agent to receive all such
presentations, surrenders, notices and demands.

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

         SECTION 1003. Money for Securities Payments to Be Held in Trust.

         If the Company shall at any time act as its own Paying Agent with
respect to any series of any Securities and any related coupons, it will, on or
before each due date of the principal of (and premium 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 Company shall have one or more Paying Agents for any
series of Securities and any related coupons, it will, on or before each due
date of the principal of (and premium or Make-Whole Amount, if any), or interest
on 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, Make-Whole
Amount or interest or Additional Amounts and (unless such Paying Agent is the
Trustee) the Company will promptly notify the Trustee of its action or failure
so to act.

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

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

                                       66
<PAGE>

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

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

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

         Except as otherwise provided in the Securities of any series, any money
deposited with the Trustee or any Paying Agent, or then held by the Company, in
trust for the payment of the principal of (and premium 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
premiums or Make-Whole Amount, if any), interest or Additional Amounts has
become due and payable shall be paid to the Company upon Company Request or (if
then held by the Company)shall be discharged from such trust; and the Holder of
such Security shall thereafter, as an unsecured general creditor, look only to
the Company for payment of such principal of (and premium or Make-Whole Amount,
if any) or interest on, 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 Company as trustee
thereof, shall thereupon cease; provided, however, that the Trustee or such
Paying Agent, before being required to make any such repayment, may at the
expense of the Company cause to be published once, in an Authorized Newspaper,
notice that such money remains unclaimed and that, after a date specified
therein, which shall not be less than 30 days from the date of such publication,
any unclaimed balance of such money then remaining will be repaid to the
Company.

         SECTION 1004. Limitations on Incurrence of Debt.

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

                                       67
<PAGE>

         securities offering proceeds received (to the extent such proceeds were
         not used to acquire real estate assets or mortgages receivable or used
         to reduce Debt), by the Company or any Subsidiary since the end of such
         calendar quarter, including those proceeds obtained in connection with
         the incurrence of such additional Debt;

                  (b) In addition to the limitations set forth in subsection (a)
         of this Section 1004, the Company will not, and will not permit any
         Subsidiary to, incur any Debt if the ratio of Consolidated Income
         Available for Debt Service to the Annual Service Charge for the four
         consecutive fiscal quarters most recently ended prior the date on which
         such additional Debt is to be incurred shall have been less than 1.5,
         on a pro forma basis after giving effect thereto and to the application
         of the proceeds therefrom, and calculated on the assumption that (i)
         such Debt and any other Debt incurred by the Company and its
         Subsidiaries since the first day of such four-quarter period and the
         application of the proceeds therefrom, including to refinance other
         Debt, had occurred at the beginning of such period; (ii) the repayment
         or retirement of any other Debt by the Company and its Subsidiaries
         since the first day of such four-quarter period had been incurred,
         repaid or retired at the beginning of such period (except that, in
         making such computation, the amount of Debt under any revolving credit
         facility shall be computed based upon the average daily balance of such
         Debt during such period); (iii) in the case of Acquired Debt or Debt
         incurred in connection with any acquisition since the first day of such
         four-quarter period, the related acquisition had occurred as of the
         first day of such period with the appropriate adjustments with respect
         to such acquisition being included in such pro forma calculation; and
         (iv) in the case of any acquisition or disposition by the Company or
         its Subsidiaries of any asset or group of assets since the first day of
         such four-quarter period, whether by merger, stock purchase or sale, or
         asset purchase or sale, such acquisition or disposition or any related
         repayment of Debt had occurred as of the first day of such period with
         the appropriate adjustments with respect to such acquisition or
         disposition being included in such pro forma calculation.

                  (c) In addition to the limitation set forth in subsections (a)
         and (b) of this Section 1004, the Company will not, and will not permit
         any Subsidiary to, incur any Debt secured by any mortgage, lien,
         charge, pledge, encumbrance or security interest of any kind upon any
         of the property of the Company or any Subsidiary, whether owned at the
         date hereof or hereafter acquired, if, immediately after giving effect
         to the incurrence of such additional Debt and the application of the
         proceeds thereof, the aggregate principal amount of all outstanding
         Debt of the Company and its Subsidiaries on a consolidated basis which
         is secured by any mortgage, lien, charge, pledge, encumbrance or
         security interest on property of the Company or any Subsidiary is
         greater than 40% of the Company's Total Assets.

                  (d) For purposes of this Section 1004 Debt shall be deemed to
         be "incurred" by the Company or a Subsidiary whenever the Company or
         such Subsidiary shall create, assume, guarantee or otherwise become
         liable in respect thereof.

         SECTION 1005. Existence.

         Subject to Article Eight, the Company will do or cause to be done all
things necessary to preserve and keep in full force and effect the existence,
rights (charter and statutory) and franchises of the Company and its
Subsidiaries; provided, however, that the Company shall not be required to
preserve any right or franchise if the Board of Directors shall determine that
the preservation thereof is no longer desirable in the conduct of the business
of the Company and its Subsidiaries as a whole and that the loss thereof is not
disadvantageous in any material respect to the Holders of Securities of any
series.

         SECTION 1006. Maintenance of Properties.

         The Company will cause all of its properties used or useful in the
conduct of its business or the business of any Subsidiary to be maintained and
kept in good condition, repair and working order and supplied with all necessary
equipment and will cause to be made all necessary repairs, renewals,
replacements, betterments and improvements thereof, all as in the judgment of
the Company may be necessary so that the business carried on in connection
therewith may be properly and advantageously conducted at all times; provided,
however, that nothing in this Section shall prevent the Company or any
Subsidiary from selling or otherwise disposing of for value its properties in
the ordinary course of its business.

         SECTION 1007. Insurance.

         The Company will, and will cause each of its Subsidiaries to, keep all
of its insurable properties insured against loss or damage at least equal to
their then full insurable value with financially sound and reputable insurance
companies.

         SECTION 1008. Payment of Taxes and Other Claims.

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

         SECTION 1009. Provision of Financial Information.

         Whether or not the Company is subject to Section 13 or 15(d) of the
Exchange Act, the Company will, to the extent permitted under the Exchange Act,
file with the Commission the annual reports, quarterly reports and other
documents which the Company would have been required to file with the Commission
pursuant to such Section 13 or 15(d) (the "Financial Statements") if the

                                       69
<PAGE>

Company were so subject, such documents to be filed with the Commission on or
prior to the respective dates (the "Required Filing Dates") by which the Trust
would have been required so to file such documents if the Company were so
subject.

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

         SECTION 1010. Statement as to Compliance.

         The Company will deliver to the Trustee within 120 days after the end
of each fiscal year, a brief certificate from the principal executive officer,
principal financial officer or principal accounting officer as to his or her
knowledge of the Company's compliance with all conditions and covenants under
this Indenture and, in the event of any noncompliance, specifying such
noncompliance and the nature and status thereof. For purposes of this Section
1010, such compliance shall be determined without regard to any period of grace
or requirement of notice under this Indenture.

         SECTION 1011. Additional Amounts.

         If any Securities of a series provide for the payment of Additional
Amounts, the Company will pay to the Holder or 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
or of any premium, 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.

         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

                                       70
<PAGE>

bear interest prior to Maturity, the first day on which a payment of principal
and any premium is made), and at least 10 days prior to each date of payment of
principal and any premium or 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 Company will furnish the Trustee and the Company's principal
Paying Agent or Paying Agents, if other than the Trustee, with an Officers'
Certificate instructing the Trustee and such Paying Agent or Paying Agents
whether such payment of principal of and any premium or interest on the
Securities of that series shall be made to Holders of Securities of that series
or any related coupons who are not United States persons without withholding for
or on account of any tax, assessment or other governmental charge described in
the Securities of or within the series. If any such withholding shall be
required, then such Officers' Certificate shall specify by country the amount,
if any, required to be withheld on such payments to such Holders of Securities
of that series or related coupons and the Company will pay to the Trustee or
such Paying Agent the Additional Amounts required by the terms of such
Securities. 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 Company
covenants to indemnify the Trustee and any Paying Agent for, and to hold them
harmless against, any loss, liability or expense reasonably incurred without
negligence or bad faith on their part arising out of or in connection with
actions taken or omitted by any of them in reliance on any Officers' Certificate
furnished pursuant to this Section or in reliance on the Company's not
furnishing such an Officers' Certificate.

         SECTION 1012. Waiver of Certain Covenants.

         The Company may omit in any particular instance to comply with any
term, provision or condition set forth in Sections 1004 to 1009, inclusive, and
with any other term, provision or condition with respect to the Securities of
any series specified in accordance with Section 301 (except any such term,
provision or condition which could not be amended without the consent of all
Holders of Securities 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 covenant or condition, but no such waiver shall extend to
or affect such covenant or condition except to the extent so expressly waived,
and, until such waiver shall become effective, the obligations of the Company
and the duties of the Trustee in respect of any such term, provision or
condition shall remain in full force and effect.

                                 ARTICLE ELEVEN

                            REDEMPTION OF SECURITIES

         SECTION 1101. Applicability of Article.

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

         SECTION 1102. Election to Redeem; Notice to Trustee.

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

         SECTION 1103. Selection by Trustee of Securities to Be Redeemed.

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

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

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

         SECTION 1104. Notice of Redemption.

         Notice of redemption shall be given in the manner provided in Section
106, not less than 30 days nor more than 60 days prior to the Redemption Date,
unless a shorter period is specified by the terms of such series established
pursuant to Section 301, to each Holder of Securities to be redeemed, but
failure to give such notice in the manner herein provided to the Holder of any

                                       72
<PAGE>

Security designated for redemption as a whole or in part, or any defect in the
notice to any such Holder, shall not affect the validity of the proceedings for
the redemption of any other such Security or portion thereof.

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

         All notices of redemption shall state:

                  (1) the Redemption Date;

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

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

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

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

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

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

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

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

                                       73
<PAGE>

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

                  (10) the CUSIP number of such Security, if any, provided that
         neither the Company nor the Trustee shall have any responsibility for
         any such CUSIP number; and

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

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

         SECTION 1106. Securities Payable on Redemption Date.

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

                                       74
<PAGE>

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

         If any Bearer Security surrendered for redemption shall not be
accompanied by all appurtenant coupons maturing after the Redemption Date, such
Security may be paid after deducting from the Redemption Price an amount equal
to the face amount of all such missing coupons, or the surrender of such missing
coupon or coupons may be waived by the Company and the Trustee if 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 Security which is to be redeemed only in part (pursuant to the
provisions of this Article or of Article Twelve) shall be surrendered at a Place
of Payment therefor (with, if the Company or the Trustee so requires, due
endorsement by, or a written instrument of transfer in form satisfactory to the
Company and the Trustee duly executed by, the Holder thereof or his attorney
duly authorized in writing) and the Company shall execute and the Trustee shall
authenticate and deliver to the Holder of such Security without service charge a
new Security or Securities of the same series, of any authorized denomination as
requested by such Holder in aggregate principal amount equal to and in exchange
for the unredeemed portion of the principal of the Security so surrendered.

                                 ARTICLE TWELVE

                                  SINKING FUNDS

         SECTION 1201. Applicability of Article.

         The provisions of this Article shall be applicable to any sinking fund
for the retirement of Securities of a series except as otherwise specified as
contemplated by Section 301 for Securities of such series.

         The minimum amount of any sinking fund payment provided for by the
terms of Securities of any series is herein referred to as a "mandatory sinking
fund payment," and any payment in excess of such minimum amount provided for by
the terms of such Securities of any series is herein referred to as an "optional
sinking fund payment." If provided for by the terms of any Securities of any
series, the cash amount of any mandatory sinking fund payment may be subject to
reduction as provided in Section 1202. Each sinking fund payment shall be
applied to the redemption of Securities of any series as provided for by the
terms of Securities of such series.

         SECTION 1202. Satisfaction of Sinking Fund Payments with Securities.

         The Company may, in satisfaction of all or any part of any mandatory
sinking fund 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 matured
coupons appertaining thereto and (2) apply as a credit Securities of such series
which have been redeemed either at the election of the Company pursuant to the
terms of such Securities or through the application of permitted optional
sinking fund payments pursuant to the terms of such Securities, as provided for
by the terms of such Securities, or which have otherwise been acquired by the
Company; provided that such Securities so delivered or applied as a credit have
not been previously so credited. Such Securities shall be received and credited
for such purpose by the Trustee at the applicable Redemption Price specified in
such Securities for redemption through operation of the sinking fund and the
amount of such mandatory sinking fund payment shall be reduced accordingly.

         SECTION 1203. Redemption of Securities for Sinking Fund.

         Not less than 60 days prior to each sinking payment date for Securities
of any series, the Company will deliver to the Trustee an Officers' Certificate
specifying the amount of the next ensuing mandatory sinking fund payment for
that series pursuant to the terms of that series, the portion thereof, if any,
which is to be satisfied by payment of cash in the currency or currencies,
currency unit or units or composite currency or currencies in which the
Securities of such series are payable (except as otherwise specified pursuant to
Section 301 for the Securities of such series) and the portion thereof, if any,

                                       76
<PAGE>

which is to be satisfied by delivering and crediting Securities of that series
pursuant to Section 1202, and the optional amount, if any, to be added in cash
to the next ensuing mandatory sinking fund payment, and will also deliver to the
Trustee any Securities to be so delivered and credited. If such Officers'
Certificate shall specify an optional amount to be added in cash to the next
ensuing mandatory sinking fund payment, the Company shall thereupon be obligated
to pay the amount therein specified. Not less than 30 days before each such
sinking fund payment date the Trustee shall select the Securities to be redeemed
upon such sinking fund payment date in the manner specified in Section 1103 and
cause notice of the redemption thereof to be given in the name of and at the
expense of the Company in the manner provided in Section 1104. Such notice
having been duly given, the redemption of such Securities shall be made upon the
terms and in the manner stated in Sections 1106 and 1107.


                                ARTICLE THIRTEEN

                       REPAYMENT AT THE OPTION OF HOLDERS

         SECTION 1301. Applicability of Article.

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

         SECTION 1303. Exercise of Option.

         Securities of any series subject to repayment at the option of the
Holders thereof will contain an "Option to Elect Repayment" form on the reverse
of such Securities. In order for any Security to be repaid at the option of the
Holder, the Trustee must receive at the Place of Payment therefor specified in
the terms of such Security (or at such other place or places of

                                       77
<PAGE>

which the Company shall from time to time notify the Holders of such Securities)
not earlier than 60 days nor later than 30 days prior to the Repayment Date (1)
the Security so providing for such repayment together with the "Option to Elect
Repayment" form on the reverse thereof duly completed by the Holder (or by the
Holder's attorney duly authorized in writing) or (2) a telegram, telex,
facsimile transmission or a letter from a member of a national securities
exchange, or the National Association of Securities Dealers, Inc. ("NASD"), or a
commercial bank or trust company in the United States setting forth the name of
the Holder of the Security, the principal amount of the Security, the principal
amount of the Security to be repaid, the CUSIP number, if any, or a description
of the tenor and terms of the Security, a statement that the option to elect
repayment is being exercised thereby and a guarantee that the Security to be
repaid, together with the duly completed form entitled "Option to Elect
Repayment" on the reverse of the Security, will be received by the Trustee not
later than the fifth Business Day after the date of such telegram, telex,
facsimile transmission or letter; provided, however, that such telegram, telex,
facsimile transmission or letter shall only be effective if such Security and
form duly completed are received by the Trustee by such fifth Business Day. If
less than the entire principal amount of such Security is to be repaid in
accordance with the terms of such Security, the principal amount of such
Security to be repaid, in increments of the minimum denomination for Securities
of such series, and the denomination or denominations of the Security or
Securities to be issued to the Holder for the portion of the principal amount of
such Security surrendered that is not to be repaid, must be specified. The
principal amount of any Security providing for repayment at the option of the
Holder thereof may not be repaid in part if, following such repayment, the
unpaid principal amount of such Security would be less than the minimum
authorized denomination of Securities of or within 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 Company on the Repayment Date therein
specified, and on and after such Repayment Date (unless the Company shall
default in the payment of such Securities on such Repayment Date) such
Securities shall, if the same were interest-bearing, cease to bear interest and
the coupons for such interest appertaining to any Bearer Securities so to be
repaid, except to the extent provided below, shall be void. Upon surrender of
any such Security for repayment in accordance with such provisions, together
with all coupons, if any, appertaining thereto maturing after the Repayment
Date, the principal amount of such security so to be repaid shall be paid by the
Company, together with accrued interest, if any, to the Repayment Date;
provided, however, that coupons whose Stated Maturity is on or prior to the
Repayment Date shall be payable only at an office or agency located outside the
United States (except as otherwise provided in Section 1002) and, unless
otherwise specified pursuant to Section 301, only upon presentation and
surrender of such coupons; and provided further that,

                                       78
<PAGE>

in the case of Registered Securities, installments of interest, if any, whose
Stated Maturity is on or prior to the Repayment Date shall be payable (but
without interest thereon, unless the Company shall default in the payment
thereof) to the Holders of such Securities, or one or more Predecessor
Securities, registered as such at the close of business on the relevant Record
Dates according to their terms and the provisions of Section 307.

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

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

         SECTION 1305. Securities Repaid in Part.

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

                                ARTICLE FOURTEEN

                       DEFEASANCE AND COVENANT DEFEASANCE

         SECTION 1401. Applicability of Article; Company's Option to Effect
Defeasance or Covenant Defeasance.

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

         SECTION 1402 Defeasance and Discharge.

         Upon the Company's exercise of the above option applicable to this
Section with respect to any Securities of or within a series, the Company shall
be deemed to have been discharged from its obligations with respect to such
Outstanding Securities and any coupons appertaining thereto on the date the
conditions set forth in Section 1404 are satisfied (hereinafter, "defeasance").
For this purpose, such defeasance means that the Company shall be deemed to have
paid and discharged the entire indebtedness represented by such Outstanding
Securities and any coupons appertaining thereto, which shall thereafter be
deemed to be "Outstanding" only for the purposes of Section 1405 and the other
Sections of this Indenture referred to in clauses (A) and (B) below, and to have
satisfied all of its other obligations under such Securities and any coupons
appertaining thereto and this Indenture insofar as such Securities and any
coupons appertaining thereto are concerned (and the Trustee, at the expense of
the Company, shall execute proper instruments acknowledging the same), except
for the following which shall survive until otherwise terminated or discharged
hereunder: (A) the rights of Holders of such Outstanding Securities and any
coupons appertaining thereto to receive, solely from the trust fund described in
Section 1404 and as more fully set forth in such Section, payments in respect of
the principal of (and premium or Make-Whole Amount, if any) and interest, if
any, on such Securities and any coupons appertaining thereto when such payments
are due, (B) the Company's obligations with respect to such Securities under
Sections 305, 306, 1002 and 1003 and with respect to the payment of Additional
Amounts, if any, on such Securities as contemplated by Section 1011, (C) the
rights, powers, trusts, duties and immunities of the Trustee hereunder and (D)
this Article. Subject to compliance with this Article Fourteen, the Company may
exercise its option under this Section notwithstanding the prior exercise of its
option under Section 1403 with respect to such Securities and any coupons
appertaining thereto.

                                       80
<PAGE>

         SECTION 1403. Covenant Defeasance.

         Upon the Company's exercise of the above option applicable to this
Section with respect to any Securities of or within a series, the Company shall
be released from its obligations under Sections 1004 to 1009, inclusive, and, if
specified pursuant to Section 301, its obligations under any other covenant,
with respect to such Outstanding Securities and any coupons appertaining thereto
on and after the date the conditions set forth in Section 1404 are satisfied
(hereinafter, "covenant defeasance"), and such Securities and any coupons
appertaining thereto shall thereafter be deemed to be not "Outstanding" for the
purposes of any direction, waiver, consent or declaration or Act of Holders (and
the consequences of any thereof) in connection with Sections 1004 to 1009,
inclusive, or such other covenant, but shall continue to be deemed "Outstanding"
for all other purposes hereunder. For this purpose, such covenant defeasance
means that, with respect to such Outstanding Securities and any coupons
appertaining thereto, the Company may omit to comply with and shall have no
liability in respect of any term, condition or limitation set forth in any such
Section or such other covenant, whether directly or indirectly, by reason of any
reference elsewhere herein to any such Section or such other covenant or by
reason of reference in any such Section or such other covenant to any other
provision herein or in any other document and such omission to comply shall not
constitute a default or an Event of Default under Section 501(4) or 501(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 Company shall irrevocably have deposited or caused to
         be deposited with the Trustee (or another trustee satisfying the
         requirements of Section 607 who shall agree to comply with the
         provisions of this Article Fourteen applicable to it) as trust funds in
         trust for the purpose of making the following payments, specifically
         pledged as security for, and dedicated solely to, the benefit of the
         Holders of such Securities and any coupons appertaining thereto, (1) an
         amount in such currency, currencies or currency unit in which such
         Securities and any coupons appertaining thereto are then specified as
         payable at Stated Maturity, or (2) Government Obligations applicable to
         such Securities and coupons appertaining thereto (determined on the
         basis of the currency, currencies or currency unit in which such
         Securities and coupons appertaining thereto are then specified as
         payable at Stated Maturity) which through the scheduled payment of
         principal and interest in respect thereof in accordance with their
         terms will provide, not later than one day before 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 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

                                       81
<PAGE>

         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; provided, that the
         Trustee shall have been irrevocably instructed to apply such money or
         the proceeds of such Government Obligations to said payments with
         respect to such Securities. Before such a deposit, the Company may give
         to the Trustee, in accordance with Section 1102 hereof, a notice of its
         election to redeem all or any portion of such Outstanding Securities at
         a future date in accordance with the terms of the Securities of such
         series and Article Eleven hereof, which notice shall be irrevocable.
         Such irrevocable redemption notice, if given, shall be given effect in
         applying the foregoing.

                  (b) Such defeasance or covenant defeasance shall not result in
         a breach or violation of, or constitute a default under, this Indenture
         or any other material agreement or instrument to which the Company is a
         party or by which it is bound (and shall not cause the Trustee to have
         a conflicting interest pursuant to Section 310(b) of the TIA with
         respect to any Security of the Company).

                  (c) No Event of Default or event which with notice or lapse of
         time or both would become an Event of Default with respect to such
         Securities and any coupons appertaining thereto shall have occurred and
         be continuing on the date of such deposit or, insofar as Sections
         501(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 Company
         shall have delivered to the Trustee an Opinion of Counsel stating that
         (i) the Company has received from, or there has been published by, the
         Internal Revenue Service a ruling, or (ii) since the date of execution
         of this Indenture, there has been a change in the applicable Federal
         income tax law, in either case to the effect that, and based thereon
         such opinion shall confirm that, the Holders of such Outstanding
         Securities and any coupons appertaining thereto will not recognize
         income, gain or loss for Federal income tax purposes as a result of
         such defeasance and will be subject to Federal income tax on the same
         amounts, in the same manner and at the same times as would have been
         the case if such defeasance had not occurred.

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

                                       82
<PAGE>

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

                  (g) After the 91st day following the deposit, the trust funds
         will not be subject to the effect of any applicable bankruptcy,
         insolvency, reorganization or similar laws affecting creditors' rights
         generally.

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

         SECTION 1405. Deposited Money and Government Obligations to Be Held in
Trust; Other Miscellaneous Provisions.

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

waiver or other action that this Indenture expressly provides may be made, given

         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 Company or by Holders of Securities as provided in
         Section 1502(b), in which case the Company or the Holders of Securities
         of or within 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.

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

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

         SECTION 1506. Counting Votes and Recording Action of Meetings.

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

         SECTION 1507. Evidence of Action Taken by Holders.

         Any request, demand, authorization, direction, notice, consent, waiver
or other action provided by this Indenture to be given or taken by a specified
percentage in principal amount of the Holders of any or all series may be
embodied in and evidenced by one or more instruments of substantially similar

expressly provided, such action shall become effective when such instrument or
instruments are delivered to the Trustee. Proof of execution of any instrument
or of a writing appointing any such agent shall be sufficient for any purpose of

and the Company, if made in the manner provided in this Article.

         SECTION 1508. Proof of Execution of Instruments.

         Subject to Article Six, the execution of any instrument by a Holder or
his agent or proxy may be proved in accordance with such reasonable rules and
regulations as may be prescribed by the Trustee or in such manner as shall be
satisfactory to the Trustee

and who hold the Securities through such United States financial institutions on

financial institution hereby agrees, on its own behalf or through its agent,
that you may advise Property Company of America or its agent that such financial
institution will provide a certificate within a reasonable time stating that it
