         Securities may be embodied in and evidenced by one or more instruments
         of substantially similar tenor signed by such Holders or holders of
         Preferred Securities, as applicable, in person or by an agent duly
         appointed in writing. If, but only if, Securities of a series are

         Securities of such series or by holders of Preferred Securities voting
         in favor thereof, either in person or by proxies duly appointed in
         writing, at any meeting of Holders of Securities of such series duly

         embodied therein and evidenced thereby) are herein sometimes referred
         to as the "Act" of the Holders or holders of Preferred Securities
         signing such instrument or instruments or so voting at any such
         meeting. Proof of

                                       12
<PAGE>

         execution of any such instrument or of a writing appointing any such
         agent, or of the holding by any Person of a Security, shall be
         sufficient for any purpose of this Indenture and (subject to Section
         315 of the Trust Indenture Act) 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 104. The record of any meeting of
         Holders of Securities shall be proved in the manner provided in Section
         1406.

                  Without limiting the generality of this Section 104, unless
         otherwise provided in or pursuant to this Indenture, a Holder,
         including a U.S. Depository that is a Holder of a global Security, may
         make, give or take, by a proxy, or proxies, duly appointed in writing,
         any request, demand, authorization, direction, notice, consent, waiver
         or other Act provided in or pursuant to this Indenture to be made,
         given or taken by Holders, and a U.S. Depository that is a Holder of a
         global Security may provide its proxy or proxies to the beneficial
         owners of interests in any such global Security through such U.S.
         Depository's standing instructions and customary practices.

                  The Trustee shall fix a record date for the purpose of
         determining the Persons who are beneficial owners of interest in any
         permanent global Security held by a U.S. Depository entitled under the
         procedures of such U.S. Depository to make, give or take, by a proxy or
         proxies duly appointed in writing, any request, demand, authorization,
         direction, notice, consent, waiver or other Act provided in or pursuant
         to this Indenture to be made, given or taken by Holders. If such a
         record date is fixed, the Holders on such record date or their duly
         appointed proxy or proxies, and only such Persons, shall be entitled to
         make, give or take such request, demand, authorization, direction,
         notice, consent, waiver or other Act, whether or not such Holders
         remain Holders after such record date. No such request, demand,
         authorization, direction, notice, consent, waiver or other Act shall be
         valid or effective if made, given or taken more than 90 days after such
         record date.

                  (2) The fact and date of the execution by any Person of any
         such instrument or writing may be proved in any reasonable manner which
         the Trustee deems sufficient and in accordance with such reasonable
         rules as the Trustee may determine; and the Trustee may in any instance
         require further proof with respect to any of the matters referred to in
         this Section 104.

                  (3) The ownership, principal amount and serial numbers of
         Registered Securities held by any Person, and the date of the
         commencement and the date of the termination of holding the same, shall
         be proved by the Security Register.

                  (4) The ownership, principal amount and serial numbers of
         Bearer Securities held by any Person, and the date of the commencement
         and the date of the termination of holding the same, 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
         reasonably acceptable to the Company, wherever situated, if such
         certificate shall be deemed by the Company and 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

                                       13
<PAGE>

         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, principal amount and serial numbers
         of Bearer Securities held by the Person so executing such instrument or
         writing and the date of the commencement and the date of the
         termination of holding the same may also be proved in any other manner
         which the Company and the Trustee deem sufficient.

                  (5) If the Company shall solicit from the Holders of any
         Registered Securities any request, demand, authorization, direction,
         notice, consent, waiver or other Act, the Company may at its option
         (but is not obligated to), by Board Resolution, fix in advance a record
         date for the determination of Holders of Registered Securities entitled
         to give such request, demand, authorization, direction, notice,
         consent, waiver or other Act. 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 Registered Securities of record at the close of business on
         such record date shall be deemed to be Holders for the purpose 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 of Registered Securities shall be deemed
         effective unless it shall become effective pursuant to the provisions
         of this Indenture not later than six months after the record date.

                  (6) Any request, demand, authorization, direction, notice,
         consent, waiver or other Act by 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 or
         suffered to be done by the Trustee, any Security Registrar, any Paying
         Agent, any Conversion Agent or the Company in reliance thereon, whether
         or not notation of such Act is made upon such Security.

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

                  Any request, demand, authorization, direction, notice,
consent, waiver or other Act of Holders or holders of Preferred Securities 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 holder of a Preferred
         Security or 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: Institutional Trust Services, or

                                       14
<PAGE>

                  (2) the Company by the Trustee or any Holder or holder of a
         Preferred Security 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 the attention
         of its Treasurer at the address of its principal office specified in
         the first paragraph of this instrument or at any other address
         previously furnished in writing to the Trustee by the Company.

         Section 106. Notice to Holders of Securities; Waiver.

                  Except as otherwise expressly provided in or pursuant to this
Indenture, where this Indenture provides for notice to Holders of Securities of
any event,

                  (1) such notice shall be sufficiently given to Holders of
         Registered Securities if in writing and mailed, first-class postage
         prepaid, to each Holder of a Registered Security 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; and

                  (2) such notice shall be sufficiently given to Holders of
         Bearer Securities, if any, if published in an Authorized Newspaper in
         The City of New York and, if such Securities are then listed on any
         stock exchange outside the United States, in an Authorized Newspaper in
         such city as the Company shall advise the Trustee that such stock
         exchange so requires, on a Business Day at least twice, the first such
         publication to be not earlier than the earliest date and the second
         such publication not later than the latest 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 of a Registered Security 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 which is mailed in the manner herein
provided shall be conclusively presumed to have been duly given or provided. In
case by reason of the suspension of regular mail service or by reason of any
other cause it shall be impracticable to give such notice by mail, then such
notification as shall be made with the approval of the Trustee shall constitute
a sufficient notification for every purpose hereunder.

                  In case 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 failure to give notice by
publication to Holders of Bearer Securities as provided above, nor any defect in
any notice so published, shall affect the sufficiency of any notice mailed to
Holders of Registered Securities as provided above.

                  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,

                                       15
<PAGE>

and such waiver shall be the equivalent of such notice. Waivers of notice by
Holders of Securities shall be filed with the Trustee, but such filing shall not
be a condition precedent to the validity of any action taken in reliance upon
such waiver.

         Section 107. Language of Notices.

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

         Section 108. Conflict with Trust Indenture Act.

                  If any provision hereof limits, qualifies or conflicts with
any duties under any required provision of the Trust Indenture Act imposed
hereon by Section 318(c) thereof, such required provision shall control.

         Section 109. Effect of Headings and Table of Contents.

Contents are for convenience only and shall not affect the construction hereof.

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

         Section 111. Separability Clause.

                  In case any provision in this Indenture, any Security or any
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 112. Benefits of Indenture.

                  Except as otherwise expressly provided herein with respect to
holders of Senior Indebtedness and holders of Preferred Securities, nothing in
this Indenture, any Security or any Coupon, express or implied, shall give to
any Person, other than the parties hereto, any Security Registrar, any Paying
Agent, any Conversion Agent and their successors hereunder and the Holders of
Securities or Coupons, any benefit or any legal or equitable right, remedy or
claim under this Indenture.

         Section 113. Governing Law.

                  This Indenture, the Securities and any Coupons shall be

following any Change in Control Purchase Date or Stated Maturity or Maturity of
any Security, or the last date on which a Holder has the right to convert or
exchange Securities of a series that are convertible or exchangeable, shall be a

of this Indenture, any Security or any Coupon other than a provision in any
Security or Coupon that specifically states that such provision shall apply in
lieu hereof) payment need not be made at such Place of Payment on such date, and
such Securities need not be converted or exchanged on such date but such payment
may be made, and such Securities may be converted or exchanged, on the next
succeeding day that is a Business Day at such Place of Payment with the same
force and effect as if made on the Interest Payment Date or at the Stated
Maturity or Maturity or on such last day for conversion or exchange, and no
Interest shall accrue on the amount payable on such date or at such time for the
period from and after such Interest Payment Date, Business Day following any
Change in Control Purchase Date, Stated Maturity, Maturity or last day for
conversion or exchange, as the case may be, to the next succeeding Business Day.

Indenture to make payments in the Required Currency (i) shall not be discharged
or satisfied by any tender, or any recovery pursuant to any judgment (whether or
not entered in accordance with clause (a)), in any currency other than the
Required Currency, except to the extent that such tender or recovery shall
result in the actual receipt, by the payee, of the full amount of the Required
Currency expressed to be payable in respect of such payments, (ii) shall be
enforceable as an alternative or additional cause of action for the purpose of
recovering in the Required Currency the amount, if any, by which such actual

expressed to be payable and (iii) shall not be affected by judgment being

         Section 203. Securities in Global Form.

                  Unless otherwise provided in or pursuant to this Indenture or
any Securities, the Securities shall not be issuable in temporary or permanent
global form. If Securities of a series shall be issuable in global form, any
such Securities may provide that it or any number of such Securities shall
represent the aggregate amount of all Outstanding Securities of such series (or
such lesser amount as is permitted by the terms thereof) from time to time
endorsed thereon and may also provide that the aggregate amount of Outstanding
Securities represented thereby may from time to time be increased or reduced to
reflect exchanges. Any endorsement of any Security

                                       18

in global form to reflect the amount, or any increase or decrease in the amount,
or changes in the rights of Holders, of Outstanding Securities represented
thereby shall be made in such manner and by such Person or Persons as shall be
specified therein or in the Company Order to be delivered pursuant to Section
303 or 304 with respect thereto. Subject to the provisions of Section 303 and,
if applicable, Section 304, 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 a Security in global form shall
be in writing but need not be accompanied by or contained in an Officers'
Certificate and need not be accompanied by an Opinion of Counsel.

                  Notwithstanding the provisions of Section 307, unless
otherwise specified in or pursuant to this Indenture or any Securities, payment
of principal of, any premium and Interest on, and any Additional Amounts in
respect of, any Security in temporary or 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 the Holder of a global security in
registered form as the Holder of the principal amount of Outstanding Securities
represented by such global Security.

<PAGE>

                  Securities and any 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, together with
any Coupons appertaining thereto, executed by the Company, to the Trustee for
authentication and, provided that the Board Resolution and Officers' Certificate
or supplemental indenture or indentures with respect to such Securities referred
to in Section 301 and a Company Order for the authentication and delivery of
such Securities have been delivered to the Trustee, the Trustee in accordance
with the Company Order and subject to the provisions hereof and of such
Securities shall authenticate and deliver such Securities. In authenticating
such Securities, and accepting the additional responsibilities under this
Indenture in relation to such Securities and any Coupons appertaining thereto,
the Trustee shall be entitled to receive, and (subject to Sections 315(a)
through 315(d) of the Trust Indenture Act) shall be fully protected in relying
upon,

                  (1)      an Opinion of Counsel to the effect that:

                           (a) the form or forms and terms of such Securities
                  and Coupons, if any, have been established in conformity with
                  the provisions of this Indenture;(b) all conditions precedent
                  to the authentication and delivery of such Securities and
                  Coupons, if any, appertaining thereto, have been complied with
                  and that such Securities, and Coupons, when completed by
                  appropriate insertions, executed under the Company's corporate
                  seal and attested by duly authorized officers of the Company,
                  delivered by duly authorized officers of the Company to the
                  Trustee for authentication pursuant to this Indenture, and
                  authenticated and delivered by the Trustee and issued by the
                  Company in the manner and subject to any conditions specified
                  in such Opinion of Counsel, will constitute legally valid and
                  binding obligations of the Company, enforceable against the
                  Company in accordance with their terms, except as enforcement
                  thereof may be subject to or limited by bankruptcy,
                  insolvency, reorganization, moratorium, arrangement,
                  fraudulent conveyance, fraudulent transfer or other similar
                  laws relating to or affecting creditors' rights generally, and
                  subject to general principles of equity (regardless of whether
                  enforcement is sought in a proceeding in equity or at law) and
                  will entitle the Holders thereof to the benefits of this
                  Indenture; such Opinion of Counsel need express no opinion as
                  to the availability of equitable remedies;

                           (c) all laws and requirements in respect of the
                  execution and delivery by the Company of such Securities and
                  Coupons, if any, have been complied with; and

                           (d) this Indenture has been qualified under the Trust
                  Indenture Act; and

                                       24
<PAGE>

                  (2) an Officers' Certificate stating that, to the best
         knowledge of the Persons executing such certificate, no event which is,
         or after notice or lapse of time or both would become, an Event of
         Default with respect to any of the Securities shall have occurred and
         be continuing.

                  If all the Securities of any series are not to be issued at
one time, it shall not be necessary to deliver an Opinion of Counsel and an
Officers' Certificate at the time of issuance of each Security, but such opinion
and certificate, with appropriate modifications, shall be delivered at or before
the time of issuance of the first Security of such series. After any such first
delivery, any separate request by the Company that the Trustee authenticate
Securities of such series for original issue will be deemed to be a
certification by the Company that all conditions precedent provided for in this
Indenture relating to authentication and delivery of such Securities continue to
have been complied with.

                  The Trustee shall not be required to authenticate or to cause
an Authenticating Agent to authenticate any Securities if the issue of such
Securities pursuant to this Indenture will affect the Trustee's own rights,
duties or immunities under the Securities and this Indenture or otherwise in a
manner which is not reasonably acceptable to the Trustee or if the Trustee,
being advised by counsel, determines that such action may not lawfully be taken.

                  Each Registered Security shall be dated the date of its
authentication. Each Bearer Security and any Bearer Security in global form
shall be dated as of the date specified in or pursuant to this Indenture.

                  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 a certificate of authentication
substantially in the form provided for in Section 202 or 611 executed by or on
behalf of the Trustee or by the Authenticating Agent by the manual signature of
one of its authorized officers. Such certificate upon any Security shall be
conclusive evidence, and the only evidence, that such Security has been duly
authenticated and delivered hereunder. Except as permitted by Section 306 or
307, the Trustee shall not authenticate and deliver any Bearer Security unless
all Coupons appertaining thereto then matured have been detached and cancelled.

         Section 304. Temporary Securities.

                  Pending the preparation of definitive Securities, the Company
may execute and deliver to the Trustee and, upon Company Order, the Trustee
shall authenticate and deliver, in the manner provided in Section 303, temporary
Securities in lieu thereof 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 of pursuant to this
Indenture, in bearer form with one or more Coupons or without Coupons and with
such appropriate insertions, omissions, substitutions and other variations as
the officers of the Company executing such Securities may determine, as
conclusively evidenced by their execution of such Securities. 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 the provisions thereof, if temporary
Securities are issued, the Company shall cause definitive Securities to be
prepared without unreasonable delay. After the preparation of definitive
Securities of the same series and containing terms and provisions that are
identical to those of any temporary Securities, such temporary Securities shall
be exchangeable for such definitive Securities upon surrender of such temporary
Securities at an Office or Agency for such Securities, without charge to any
Holder thereof. Upon surrender for cancellation of any one or more temporary
Securities (accompanied by any unmatured 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 authorized
denominations of the same series and containing identical terms and provisions;
provided, however, that no definitive Bearer Security, except as provided in or
pursuant to this Indenture, 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 or pursuant to this Indenture.
Unless otherwise provided in or pursuant to this Indenture with respect to a
temporary global Security, until so exchanged the temporary Securities of any
series shall in all respects be entitled to the same benefits under this
Indenture as definitive Securities of such series.

         Section 305. Registration, Transfer and Exchange.

                  With respect to the Registered Securities of each series, if
any, the Company shall cause to be kept a register (each such register being
herein sometimes referred to as the "Security Register") at an Office or Agency
for such series in which, subject to such reasonable regulations as it may
prescribe, the Company shall provide for the registration of the Registered
Securities of such series and of transfers of the Registered Securities of such
series. Such Office or Agency shall be the "Security Registrar" for that series
of Securities. Unless otherwise specified in or pursuant to this Indenture or
the Securities, the Trustee shall be the initial Security Registrar for each
series of Securities. The Company shall have the right to remove and replace
from time to time the Security Registrar for any series of Securities; provided
that no such removal or replacement shall be effective until a successor
Security Registrar with respect to such series of Securities shall have been
appointed by the Company and shall have accepted such appointment by the
Company. In the event that the Trustee shall not be or shall cease to be
Security Registrar with respect to a series of Securities, it shall have the
right to examine the Security Register for such series at all reasonable times.
There shall be only one Security Register for each series of Securities.

                  Upon surrender for registration of transfer of any Registered
Security of any series at any Office or Agency for such 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 denominated as authorized in or pursuant to this Indenture,
of a like aggregate principal amount bearing a number not contemporaneously
outstanding and containing identical terms and provisions.

                  At the option of the Holder, Registered Securities of any
series may be exchanged for other Registered Securities of the same series
containing identical terms and provisions, in any authorized denominations, and
of a like aggregate principal amount, upon surrender of the

                                       26
<PAGE>

Securities to be exchanged at any Office or Agency for such series. Whenever any
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.

                  If provided in or pursuant to this Indenture, with respect to
Securities of any series, at the option of the Holder, Bearer Securities of such
series may be exchanged for Registered Securities of such series containing
identical terms, denominated as authorized in or pursuant to this Indenture and
in the same aggregate principal amount, upon surrender of the Bearer Securities
to be exchanged at any Office or Agency for such series, 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, such exchange may be effected if the
Bearer Securities are accompanied by payment in funds acceptable to the Company
and the Trustee in an amount equal to the face amount of such missing Coupon or
Coupons, or the surrender of such missing Coupon or Coupons may be waived by the
Company and the Trustee if there is furnished to them such security or indemnity
as they may require to save each of them and any Paying Agent harmless. If
thereafter the Holder of such Bearer Security shall surrender to any Paying
Agent any such missing Coupon in respect of which such a payment shall have been
made, such Holder shall be entitled to receive the amount of such payment;
provided, however, that, except as otherwise provided in Section 1002, Interest
represented by Coupons shall be payable only upon presentation and surrender of
those Coupons at an Office or Agency for such series located outside the United
States. Notwithstanding the foregoing, in case a Bearer Security of any series
is surrendered at any such Office or Agency for such series in exchange for a
Registered Security of such 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 date for payment of Defaulted Interest, such Bearer
Security shall be surrendered without the Coupon relating to such Interest
Payment Date or proposed date of payment, as the case may be (or, if such Coupon
is so surrendered with such Bearer Security, such Coupon shall be returned to
the Person so surrendering the Bearer Security), and Interest or Defaulted
Interest, as the case may be, shall 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 shall be payable only
to the Holder of such Coupon when due in accordance with the provisions of this
Indenture.

                  If provided in or pursuant to this Indenture with respect to
Securities of any series, at the option of the Holder, Registered Securities of
such series may be exchanged for Bearer Securities upon such terms and
conditions as may be provided in or pursuant to this Indenture with respect to
such series.

                  Whenever any Securities are surrendered for exchange as
contemplated by the immediately preceding two paragraphs, the Company shall
execute, and the Trustee shall authenticate and deliver, the Securities which
the Holder making the exchange is entitled to receive.

                                       27
<PAGE>

                  Notwithstanding the foregoing, except as otherwise provided in
or pursuant to this Indenture, any global Security shall be exchangeable for
definitive Securities only if (i) the Depository is at any time unwilling,
unable or ineligible to continue as Depository and a successor depository is not
appointed by the Company within 90 days of the date the Company is so informed
in writing, (ii) the Company executes and delivers to the Trustee a Company
Order to the effect that such global Security shall be so exchangeable, or (iii)
an Event of Default has occurred and is continuing with respect to the
Securities. If the beneficial owners of interests in a global Security are
entitled to exchange such interests for definitive Securities as the result of
an event described in clause (i), (ii) or (iii) of the preceding sentence, then
without unnecessary delay but in any event not later than the earliest date on
which such interests may be so exchanged, the Company shall deliver to the
Trustee definitive Securities in such form and denominations as are required by
or pursuant to this Indenture, and of the same series, containing identical
terms and in aggregate principal amount equal to the principal amount of such
global Security, executed by the Company. On or after the earliest date on which
such interests may be so exchanged, such global Security shall be surrendered
from time to time by the U.S. Depository or such other Depository as shall be
specified in the Company Order with respect thereto, and in accordance with
instructions given to the Trustee and the U.S. Depository or such other
Depository, as the case may be (which instructions shall be in writing but need
not be contained in or accompanied by an Officers' Certificate or be accompanied
by an Opinion of Counsel), as shall be specified in the Company Order with
respect thereto to the Trustee, as the Company's agent for such purpose, to be
exchanged, in whole or in part, for definitive Securities as described above
without charge. The Trustee shall authenticate and make available for delivery,
in exchange for each portion of such surrendered global Security, a like
aggregate principal amount of definitive Securities of the same series of
authorized denominations and of like tenor as the portion of such global
Security to be exchanged, which (unless such Securities are not issuable both as
Bearer Securities and as Registered Securities, in which case the definitive
Securities exchanged for the global Security shall be issuable only in the form
in which the Securities are issuable, as provided in or pursuant to this
Indenture) shall be in the form of Bearer Securities or Registered Securities,
or any combination thereof, as shall be specified by the beneficial owner
thereof, but subject to the satisfaction of any certification or other
requirements to the issuance of Bearer Securities; provided, however, that no
such exchanges may occur during a period beginning at the opening of business 15
days before any selection of Securities of the same series to be redeemed and
ending on the relevant Redemption Date; and provided, further, that (unless
otherwise provided in or pursuant to this Indenture) no Bearer Security
delivered in exchange for a portion of a global Security shall be mailed or
otherwise delivered to any location in the United States. Promptly following any
such exchange in part, such global Security shall be returned by the Trustee to
such Depository or the U.S. Depository, as the case may be, or such other
Depository or U.S. Depository referred to above in accordance with the
instructions of the Company referred to above. If a Registered Security is
issued in exchange for any portion of a global Security after the close of
business at the Office or Agency for such Security where such exchange occurs on
or after (i) any Regular Record Date for such Security and before the opening of
business at such Office or Agency on the next Interest Payment Date, or (ii) any
Special Record Date for such Security and before the opening of business at such
Office or Agency on the related proposed date for payment of Interest or
Defaulted Interest, as the case may be, Interest shall not be payable on such
Interest Payment Date or proposed date for payment, as the case may be, in
respect of such Registered Security,

                                       28
<PAGE>

but shall 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 global Security shall be 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 entitling the Holders thereof to the same benefits under this
Indenture as the Securities surrendered upon such registration of transfer or
exchange.

                  Every Registered Security presented or surrendered for
registration of transfer or for exchange or redemption shall (if so required by
the Company or the Security Registrar for such Security) be duly endorsed, or be
accompanied by a written instrument of transfer in form satisfactory to the
Company and the Security Registrar for such Security 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, or redemption of Securities, but the Company or the
Trustee may require payment of a sum sufficient to cover any tax or other
governmental charge.

                  Except as otherwise provided in or pursuant to this Indenture,
the Company shall not be required (i) to issue, register the transfer of or
exchange any Securities during a period beginning at the opening of business 15
days before the day of the selection for redemption of Securities of like tenor
and the same series under Section 1103 and ending at the close of business on
the day of such selection, 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 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, to the extent provided with respect to such Bearer Security, that such
Bearer Security may be exchanged for a Registered Security of like tenor and the
same series, provided that such Registered Security shall be immediately
surrendered for redemption with written instruction for payment consistent with
the provisions of this Indenture or (iv) to issue, register the transfer of or
exchange any Security which, in accordance with its terms, 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, subject to the
provisions of this Section 306, the Company shall execute and the Trustee shall
authenticate and deliver in exchange therefor a new Security of the same series
containing identical terms and of like principal amount and bearing a number not
contemporaneously outstanding, with Coupons appertaining thereto corresponding
to the Coupons, if any, appertaining to the surrendered Security.

                  If there be delivered to the Company and to the Trustee (i)
evidence to their satisfaction of the destruction, loss or theft of any Security
or Coupon, and (ii) such security or indemnity as may be required by them to
save each of them and any agent of either of them harmless, then, in the absence
of notice to the Company or the Trustee that such Security or

                                       29
<PAGE>

Coupon has been acquired by a protected purchaser, the Company shall execute
and, upon Company Request the Trustee shall authenticate and deliver, in
exchange for or in lieu of any such mutilated, 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 containing identical terms and of like principal
amount and bearing a number not contemporaneously outstanding, with Coupons
corresponding to the Coupons, if any, appertaining to such destroyed, lost or
stolen Security or to the Security to which such destroyed, lost or stolen
Coupon appertains.

                  Notwithstanding the foregoing provisions of this Section 306,
in case any 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, pay such Security or Coupon; provided,
however, that principal of, any premium or Interest on or any Additional Amounts
with respect to any Bearer Securities shall, except as otherwise provided in
Section 1002, be payable only at an Office or Agency for such Securities located
outside the United States and, unless otherwise provided in or pursuant to this
Indenture, any Interest on Bearer Securities and any Additional Amounts with
respect to such Interest shall be payable only upon presentation and surrender
of the Coupons appertaining thereto.

                  Upon the issuance of any new Security under this Section 306,
the Company or the Trustee 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, with any Coupons appertaining thereto
issued pursuant to this Section 306 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 a separate obligation of the Company, whether
or not the destroyed, lost or stolen Security and Coupons appertaining thereto
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 such series and the
Coupons, if any, duly issued hereunder.

                  The provisions of this Section 306, as amended or supplemented
pursuant to this Indenture with respect to particular Securities or generally,
shall be 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 and Certain Additional Amounts; Rights
                      to Interest and Certain Additional Amounts Preserved.

                  Unless otherwise provided in or pursuant to this Indenture,
any Interest on and any Additional Amounts with respect to any Registered
Security which shall be payable, and are punctually paid or duty provided for,
on any Interest Payment Date shall be paid to the Person in whose name such
Security (or one or more Predecessor Securities) is registered as of the close
of business on the Regular Record Date for such Interest. Unless otherwise
provided in or pursuant to this Indenture, in case a Bearer Security is
surrendered in exchange for a Registered Security after the close of business at
an Office or Agency for such Security on any Regular Record Date

                                       30
<PAGE>

therefor and before the opening of business at such Office or Agency on the next
succeeding Interest Payment Date therefor, such Bearer Security shall be
surrendered without the Coupon relating to such Interest Payment Date and
Interest shall not be payable on such Interest Payment Date in respect of the
Registered Security issued in exchange for such Bearer Security, but shall be
payable only to the Holder of such Coupon when due in accordance with the
provisions of this Indenture.

                  Unless otherwise provided in or pursuant to this Indenture,
any Interest on and any Additional Amounts with respect to any Registered
Security which shall be payable, but shall not be punctually paid or duly
provided for, on any Interest Payment Date for such Registered Security (herein
called "Defaulted Interest") shall forthwith cease to be payable to the 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 Person in whose name such Registered Security (or a
         Predecessor Security thereof) shall be 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 such Registered Security and the date of the
         proposed payment, and at the same time the Company shall deposit with
         the Trustee an amount of money equal to the aggregate amount proposed
         to be paid in respect of such Defaulted Interest or shall make
         arrangements satisfactory to the Trustee for such deposit on or prior
         to the date of the proposed payment, such money when so deposited to be
         held in trust for the benefit of the Person entitled to such Defaulted
         Interest as in this Clause provided. Thereupon, the Trustee shall fix a
         Special Record Date for the payment of such Defaulted Interest which
         shall be not more than 15 days and not less than 10 days prior to the
         date of the proposed payment and not less than 10 days after the
         receipt by the Trustee of the notice of the proposed payment. The
         Trustee shall promptly notify the Company of such Special Record Date
         and, in the name and at the expense of the Company shall cause notice
         of the proposed payment of such Defaulted Interest and the Special
         Record Date therefor to be mailed, first-class postage prepaid, to the
         Holder of such Registered Security (or a Predecessor Security thereof)
         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
         of general circulation in the Borough of Manhattan, The City of New
         York, but such publication 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 Person in whose name such Registered Security (or a Predecessor
         Security thereof) shall be 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 is surrendered at the
         Office or Agency for such Security in exchange for a Registered
         Security 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

                                       31
<PAGE>

         be surrendered without the Coupon relating to such Defaulted Interest
         and Defaulted Interest shall not be payable on such proposed date of
         payment in respect of the Registered Security issued in exchange for
         such Bearer Security, but shall 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 in
         any other lawful manner not inconsistent with the requirements of any
         securities exchange on which such Security 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 payment shall be deemed practicable by the Trustee.

                  Unless otherwise provided in or pursuant to this Indenture or
the Securities of any particular series, at the option of the Company, Interest
on Registered Securities that bear Interest may be paid by mailing a check to
the address of the Person entitled thereto as such address shall appear in the
Security Register or by transfer to an account maintained by the payee with a
bank located in the United States.

                  Subject to the foregoing provisions of this Section 307 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.

                  If any convertible or exchangeable Security of any series is
converted or exchanged after any Regular Record Date and on or prior to the next
succeeding Interest Payment Date (other than any Security with respect to which
the Stated Maturity Date is prior to such Interest Payment Date), Interest that
is due on such Interest Payment Date shall be payable on such Interest Payment
Date notwithstanding such conversion or exchange, and such Interest (whether or
not punctually paid or duly provided for ) shall be paid to the Person in whose
name that Security is registered at the close of business on such Regular Record
Date. Except as otherwise expressly provided in the immediately preceding
sentence, in the case of any Security that is converted or exchanged, Interest
shall not be payable if the Regular Record Date is after the date of conversion
or exchange of such 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 in the Security Register as the owner of such Registered Security for
the purpose of receiving payment of principal of, any premium and (subject to
Sections 305 and 307) Interest on and any Additional Amounts with respect to
such Registered Security and for all other purposes whatsoever, whether or not
any payment with respect to such Registered Security shall 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.

                  The Company, the Trustee and any agent of the Company or the
Trustee may treat the bearer of any Bearer Security or the bearer of any Coupon
as the absolute owner of such

                                       32
<PAGE>

Security or Coupon for the purpose of receiving payment thereof or on account
thereof and for all other purposes whatsoever, whether or not any payment with
respect to such Security or Coupon shall be overdue, and neither the Company,
nor the Trustee or any agent of the Company or the Trustee shall be affected by
notice to the contrary.

                  No holder of any beneficial interest in any global Security
held on its behalf by a Depository shall have any rights under this Indenture
with respect to such global Security, and such Depository may be treated by the
Company, the Trustee, and any agent of the Company or the Trustee as the owner
of such global Security for all purposes whatsoever. None of the Company, the
Trustee, any Paying Agent, any Conversion Agent or the Security Registrar will
have any responsibility or liability for any aspect of the records relating to
or payments made on account of beneficial ownership interests of a global
Security or for maintaining, supervising or reviewing any records relating to
such beneficial ownership interests.

         Section 309. Cancellation.

                  All Securities and Coupons surrendered for payment,
redemption, registration of transfer, exchange or conversion or for credit
against any sinking fund payment shall, if surrendered to any Person other than
the Trustee, be delivered to the Trustee, and any such Securities and Coupons,
as well as Securities and Coupons surrendered directly to the Trustee for any
such purpose, shall be cancelled promptly by the Trustee. 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 all Securities so delivered shall be cancelled promptly
by the Trustee. No Securities shall be authenticated in lieu of or in exchange
for any Securities cancelled as provided in this Section 309, except as
expressly permitted by or pursuant to this Indenture. All cancelled Securities
and Coupons held by the Trustee shall be destroyed by the Trustee in accordance
with its customary procedures, unless by a Company Order the Company directs
their return to it.

         Section 310. Computation of Interest.

                  Except as otherwise provided in or pursuant to this Indenture
or in any Security, Interest on the Securities shall be computed on the basis of
a 360-day year of twelve 30-day months.

                                  ARTICLE FOUR

                     SATISFACTION AND DISCHARGE OF INDENTURE

         Section 401. Satisfaction and Discharge.

                  Upon the direction of the Company by a Company Order, this
Indenture shall cease to be of further effect with respect to any series of
Securities specified in such Company Order and any Coupons appertaining thereto,
and the Trustee, on receipt of a Company Order, at the expense of the Company,
shall execute proper instruments acknowledging satisfaction and discharge of
this Indenture as to such series, when:

                  (1)      either:

                                       33
<PAGE>

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

                  have been replaced or paid as provided in Section 306, (iii)
                  Coupons appertaining to Securities of such series called for
                  redemption and maturing after the relevant Redemption Date
                  whose surrender has been waived as provided in Section 1107,
                  and (iv) Securities and Coupons of such series for whose
                  payment money in the applicable Currency has theretofore been
                  deposited in trust or segregated and held in trust by the
                  Company and thereafter repaid to the Company or discharged
                  from such trust, as provided in Section 1003) have been
                  delivered to the Trustee for cancellation; or

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

                                    (i) have become due and payable; or

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

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

         and the Company, in the case of (i), (ii) or (iii) above, has deposited
         or caused to be deposited with the Trustee as trust funds in trust for
         such purpose, money in the Currency in which such Securities are
         payable in an amount sufficient to pay and discharge the entire
         indebtedness on such Securities and any Coupons appertaining thereto
         not theretofore delivered to the Trustee for cancellation, including
         the principal of, any premium and Interest on, and any Additional
         Amounts with respect to such Securities and any Coupons appertaining
         thereto, to the date of such deposit (in the case of Securities which
         have become due and payable) or to the Maturity thereof, as the case
         may be;

                  (2) the Company has paid or caused to be paid all other sums
         payable hereunder by the Company with respect to the Outstanding
         Securities of such series and any Coupons appertaining thereto; 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.

<PAGE>

                  In the event there are Securities of two or more series
hereunder, the Trustee shall be required to execute an instrument acknowledging
satisfaction and discharge of this Indenture only if requested to do so with
respect to Securities of such series as to which it is Trustee and if the other
conditions thereto are met.

                  Notwithstanding the satisfaction and discharge of this
Indenture with respect to any series of Securities, the obligations of the
Company to the Trustee under Section 606 and, if money shall have been deposited
with the Trustee pursuant to subclause (b) of clause (1) of this Section 401,
the obligations of the Company and the Trustee with respect to the Securities of
such series under Sections 305, 306, 403, 1002, 1003 and Article Twelve, with
respect to the payment of Additional Amounts, if any, with respect to such
Securities as contemplated by Section 1004 (but only to the extent that the
Additional Amounts payable with respect to such Securities exceed the amount
deposited in respect of such Additional Amounts pursuant to subclause (b) of
clause (1) of this Section 401), and, unless otherwise provided pursuant to
Section 301 with respect to the Securities of such series, any rights to convert
or exchange the Securities of such series into other securities or rights in
accordance with their terms, shall survive.

         Section 402. Defeasance and Covenant Defeasance.

                  (1) Unless, pursuant to Section 301, either or both of (i)
         defeasance of the Securities of or within a series under clause (2) of
         this Section 402, or (ii) covenant defeasance of the Securities of or
         within a series under clause (3) of this Section 402 shall not be
         applicable with respect to the Securities of such series, then such
         provisions, together with the other provisions of this Section 402
         (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 or Officers' Certificate, at any
         time, with respect to such Securities and any Coupons appertaining
         thereto, elect to have Section 402(2) or Section 402(3) be applied to
         such Outstanding Securities and any Coupons appertaining thereto upon
         compliance with the conditions set forth below in this Section 402.

                  (2) Upon the Company's exercise of the above option applicable
         to this Section 402(2) 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 clause (4)
         of this Section 402 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
         clause (5) of this Section 402 and the other Sections of this Indenture
         referred to in clauses (i) and (ii) below, and to have satisfied all of
         its other obligations under such Securities and any Coupons

                                       35
<PAGE>

         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: (i) the rights of Holders of such
         Outstanding Securities and any Coupons appertaining thereto to receive,
         solely from the trust fund described in clause (4) of this Section 402
         and as more fully set forth in such Section, payments in respect of the
         principal of (and premium, if any) and Interest, if any, on, and
         Additional Amounts, if any, with respect to, such Securities and any
         Coupons appertaining thereto when such payments are due, and any rights
         of such Holder to convert or exchange such Securities into or for
         Common Stock or other securities, cash or property, (ii) the
         obligations of the Company and the Trustee with respect to such
         Securities under Sections 305, 306, 1002 and 1003, with respect to the
         payment of Additional Amounts, if any, on such Securities as
         contemplated by Section 1004 (but only to the extent that the
         Additional Amounts payable with respect to such Securities exceed the
         amount deposited in respect of such Additional Amounts pursuant to
         Section 402(4)(a) below), (iii) the rights, powers, trusts, duties and
         immunities of the Trustee hereunder and (iv) this Section 402. The
         Company may exercise its option under this Section 402(2)
         notwithstanding the prior exercise of its option under clause (3) of
         this Section 402 with respect to such Securities and any Coupons
         appertaining thereto.

                  (3) Upon the Company's exercise of the above option applicable
         to this Section 402(3) with respect to any Securities of or within a
         series, the Company shall, to the extent specified pursuant to Section
         301, be released from its obligations in respect of any covenant
         applicable to such Securities, with respect to such Outstanding
         Securities and any Coupons appertaining thereto on and after the date
         the conditions set forth in clause (4) of this Section 402 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 any such 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(6) or otherwise, as the case may be, but, except
         as specified above, the remainder of this Indenture and such Securities
         and Coupons appertaining thereto shall be unaffected thereby.

                  (4) The following shall be the conditions to application of
         clause (2) or (3) of this Section 402 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 Section 402 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:

                                       36

                                    (1) an amount in Dollars or in such Foreign
                           Currency 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 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 any
                           premium, Interest and Additional Amounts on such
                           Securities and any Coupons appertaining thereto,
                           money in an amount; or

                                    (3) a combination thereof;

                  in any case, in an amount, sufficient, without consideration
                  of any reinvestment of such principal and Interest, in the
                  opinion of a nationally recognized firm of independent public
                  accountants expressed in a written certification thereof
                  delivered to the Trustee, to pay and discharge, and which
                  shall be applied by the Trustee (or other qualifying trustee)
                  to pay and discharge, the principal of and any premium,
                  Interest and Additional Amounts on such Outstanding Securities
                  and any Coupons appertaining thereto on the Stated Maturity of
                  such principal or installment of principal or Interest on the
                  day on which such payments are due and payable in accordance
                  with the terms of this Indenture and of such Securities and
                  any Coupons appertaining thereto.

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

                           (c) No Event of Default or event which with notice or
                  lapse of time or both would become an Event of Default with
                  respect to such Securities and any Coupons appertaining
                  thereto shall have occurred and be continuing on the date of
                  such deposit and, with respect to defeasance only, 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 clause (2) of
                  this Section 402, the Company shall have delivered to the
                  Trustee an Opinion of Counsel stating that (i) the Company has
                  received from the Internal Revenue Service a letter ruling, or
                  there has been published by the Internal Revenue Service a
                  Revenue 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

                                       37
<PAGE>

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

                           (e) In the case of an election under clause (3) of
                  this Section 402, the Company shall have delivered to the
                  Trustee an Opinion of Counsel to the effect that the Holders
                  of such Outstanding Securities and any Coupons appertaining
                  thereto will not recognize income, gain or loss for Federal
                  income tax purposes as a result of such covenant defeasance
                  and will be subject to Federal income tax on the same amounts,
                  in the same manner and at the same times as would have been
                  the case if such covenant defeasance had not occurred.

                           (f) The Company shall have delivered to the Trustee
                  an Officers' Certificate and an Opinion of Counsel, each
                  stating that all conditions precedent to the defeasance or
                  covenant defeasance under clause (2) or (3) of this Section
                  402 (as the case may be) have been complied with.

                           (g) Notwithstanding any other provisions of this
                  Section 402(4), 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.

                  (5) 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 402(5) and Section 403, the "Trustee")
         pursuant to clause (4) of Section 402 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 of and any premium, Interest and Additional
         Amounts, but such money need not be segregated from other funds except
         to the extent required by law.

                  Unless otherwise specified in or pursuant to this Indenture or
any Security, if, after a deposit referred to in Section 402(4)(a) has been
made, (a) the Holder of a Security in respect of which such deposit was made is
entitled to, and does, elect pursuant to Section 301 or the terms of such
Security to receive payment in a Currency other than that in which the deposit
pursuant to Section 402(4)(a) has been made in respect of such Security, or (b)
a Conversion Event occurs in respect of the Foreign Currency in which the
deposit pursuant to Section 402(4)(a) has been made, the indebtedness
represented by such Security and any Coupons appertaining thereto shall be
deemed to have been, and will be, fully discharged and satisfied through the
payment of the principal of and any premium and Interest on, and any Additional
Amounts with respect to, such Security as the same becomes due out of the
proceeds yielded by converting (from time to time as specified below in the case
of any such election) the amount or other property deposited in respect of such
Security into the Currency in which such Security

                                       38
<PAGE>

becomes payable as a result of such election or Conversion Event based on (x) in
the case of payments made pursuant to clause (a) above, the applicable market
exchange rate for such Currency in effect on the second Business Day prior to
each payment date, or (y) with respect to a Conversion Event, the applicable
market exchange rate for such Foreign Currency in effect (as nearly as feasible)
at the time of the Conversion Event. Unless otherwise provided pursuant to
Section 301, the right, if any, to extend an Interest payment period shall
terminate upon defeasance or covenant defeasance, as the case may be.

                  The Company shall pay and indemnify the Trustee against any
tax, fee or other charge, imposed on or assessed against the Government
Obligations deposited pursuant to this Section 402 or the principal or Interest
received in respect thereof other than any such tax, fee or other charge which
by law is for the account of the Holders of such Outstanding Securities and any
Coupons appertaining thereto.

                  Anything in this Section 402 to the contrary notwithstanding,
the Trustee shall deliver or pay to the Company from time to time upon Company
Request any money or Government Obligations (or other property and any proceeds
therefrom) held by it as provided in clause (4) of this Section 402 which, in
the opinion of a nationally recognized firm of independent public accountants
expressed in a written certification thereof delivered to the Trustee, are in
excess of the amount thereof which would then be required to be deposited to
effect a defeasance or covenant defeasance, as applicable, in accordance with
this Section 402.

         Section 403. Application of Trust Money.

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

         Section 404. Reinstatement.

                  If the Trustee or the Paying Agent is unable to apply any
money in accordance with this Article with respect to any Securities by reason
of any order or judgment of any court or governmental authority enjoining,
restraining or other wise prohibiting such application, then the obligations
under this Indenture and such Securities from which the Company has been
discharged or released pursuant to this Article shall be revived and reinstated
as though no deposit has occurred pursuant to this Article with respect to such
Securities, until such time as the Trustee or Paying Agent is permitted to apply
all money held in trust pursuant to this Article with respect to such Securities
in accordance with this Article; provided, however, that if the Company makes
any payment of principal of or any premium or Interest on or Additional Amounts
with respect to any such Security following reinstatement of its obligations,
the

                                       39
<PAGE>

         Section 502. Acceleration of Maturity: Rescission and Annulment.

                  If an Event of Default with respect to Securities of any
series at the time Outstanding (other than an Event of Default specified in
clause (6) or (7) of Section 501) occurs and is continuing, then the Trustee or
the Holders of not less than 25% in principal amount of the Outstanding
Securities of such series may declare the principal of all the Securities of
such series, or such lesser amount as may be provided for in the Securities of
such series, to be due and payable immediately, by a notice in writing to the
Company (and to the Trustee if given by the Holders), and upon any such
declaration such principal or such lesser amount shall become immediately due
and payable; provided that in the case of a series of Securities then held by a
Trust, if upon an Event of Default with respect to the Securities of that series
the Trustee has, or the Holders of not less than 25% in principal amount of the
Outstanding Securities of such series have, failed to declare the principal of
all the Securities of such series to be due and payable

                                       41
<PAGE>

the outstanding Preferred Securities of that Trust shall have such right by a
notice in writing to the Company and to the Trustee.

                  If an Event of Default specified in clause (6) or (7) of
Section 501 occurs, all unpaid principal of and accrued Interest on the
Outstanding Securities of that series (or such lesser amount as may be provided
for in the Securities of such series) shall ipso facto become and be immediately
due and payable without any declaration or other act on the part of the Trustee
or any Holder of any Security of that series.

                  At any time after Securities of any series have been
accelerated 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 not less than a majority in principal amount of the Outstanding
Securities of such series (subject to, in the case of any series of Securities
held as assets of a Trust and with respect to which a Security Exchange has not
theretofore occurred, such consent of the holders of the Preferred Securities
and the common securities of such Trust as may be required under the Trust
Agreement of such Trust), 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
         of money sufficient to pay:

                           (a) all overdue installments of any Interest on and
                  Additional Amounts with respect to all Securities of such
                  series and any Coupon appertaining thereto;

                           (b) the principal of and any premium on any
                  Securities of such series which have become due otherwise than
                  by such declaration of acceleration and Interest thereon and
                  any Additional Amounts with respect thereto at the rate or
                  rates borne by or provided for in such Securities;

                           (c) to the extent that payment of such Interest or
                  Additional Amounts is lawful, Interest upon overdue
                  installments of any Interest and 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 all other amounts due the Trustee under Section
                  606; and

                  (2) all Events of Default with respect to Securities of such
         series, other than the non-payment of the principal of, any premium and
         Interest on, and any Additional Amounts with respect to Securities of
         such series which shall have become due solely by such declaration of
         acceleration, shall 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) there is a failure to pay any installment of Interest on
         or any Additional Amounts with respect to any Security or any Coupon
         appertaining thereto when such Interest or Additional Amounts shall
         have become due and payable and such default continues for a period of
         30 days; or

                  (2) there is a failure to pay the principal of or any premium
         on any Security at its Maturity;

the Company shall, upon demand of the Trustee, pay to the Trustee, for the
benefit of the Holders of such Securities and any Coupons appertaining thereto,
the whole amount of money then due and payable with respect to such Securities
and any Coupons appertaining thereto, with Interest upon the overdue principal,
any premium and, to the extent that payment of such Interest shall be legally
enforceable, upon any overdue installments of Interest and Additional Amounts at
the rate or rates borne by or provided for in such Securities, and, in addition
thereto, such further amount of money 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 and all other
amounts due to the Trustee under Section 606.

                  If the Company fails to pay the money it is required to pay
the Trustee pursuant to the preceding paragraph forthwith upon the demand of the
Trustee, the Trustee, in its own name and as trustee of an express trust, may
institute a judicial proceeding for the collection of the money 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
and any Coupons appertaining thereto and collect the monies 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 and any Coupons appertaining thereto,
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 Coupons appertaining thereto 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 such Securities or in aid of the exercise of any power
granted herein or therein, 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 such other obligor or their
creditors, the Trustee (irrespective of whether the principal of the Securities
shall then be due and payable as therein expressed or by declaration or
otherwise and irrespective of whether the Trustee shall have made any demand on
the Company for the payment of any

                                       43
<PAGE>

overdue principal, premium, Interest or Additional Amounts) shall be entitled
and empowered, by intervention in such proceeding or otherwise,

                  (1) 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 the principal and any premium, Interest and Additional Amounts owing
         and unpaid in respect of the Securities and any Coupons appertaining
         thereto 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 or counsel) and of the Holders of
         Securities or any Coupons allowed in such judicial proceeding, and

                  (2) to collect and receive any monies 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 or any 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 of Securities or any Coupons, to pay to the Trustee any
amount due to it for the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel and any other amounts due the
Trustee under Section 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 any 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 any Coupon in any such proceeding; provided, however,
that the Trustee may, on behalf of the Holders, vote for the election of a
trustee in bankruptcy or similar official and be a member of a creditors'
committee or other similar committee.

         Section 505. Trustee May Enforce Claim 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

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 or judgment, after provision for the payment of the reasonable
compensation, expenses, disbursements and advances of the Trustee, its agents
and counsel, shall be for the ratable benefit of each and every Holder of a
Security or Coupon in respect of which such judgment has been recovered

been determined adversely to the Trustee or to such Holder, then and in every
such case the Company, the Trustee and each such Holder 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 each such Holder shall continue as though no such proceeding had

remedy, to the extent permitted by law, shall be cumulative and in addition to
every other right and remedy given hereunder or now or hereafter existing at law

hereunder, or otherwise, shall not, to the extent permitted by law, prevent the
concurrent assertion or employment of any other appropriate right or remedy.

         Section 511. Delay or Omission Not Waiver.

                  No delay or omission of the Trustee or of any Holder of any
Security or Coupon to exercise any right or remedy accruing upon any Event of

Event of Default or an acquiescence therein. Every right and remedy given by
this Article or by law to the Trustee or to any Holder of a Security or a Coupon
may be exercised from time to time, and as often as may be deemed expedient, by
the Trustee or by such Holder, as the case may be,

right to direct the time, method and place of conducting any proceeding for any
remedy available to the Trustee or exercising any trust or power conferred on
the Trustee with respect to the Securities of such series and any Coupons
appertaining thereto, provided that:

                  (1) such direction shall not be in conflict with any rule of
         law or with this Indenture or with the Securities of any series;

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

                  (3) such direction is not unduly prejudicial to the rights of
         the other Holders of Securities of such series not joining in such
         action.

         Section 513. Waiver of Past Defaults.

                  Subject to Section 502, the Holders of not less than a

         Holder of each Outstanding Security of such series affected.

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

         Section 514. Waiver of Stay or Extension Laws.

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

         Section 515. Undertaking for Costs.

                  All parties to this Indenture agree, and each Holder of any
Security by his acceptance thereof shall be deemed to have agreed, that any
court may in its discretion require, in any suit for the enforcement of any
right or remedy under this Indenture, or in any suit against the Trustee for any
action taken or omitted by it as Trustee, the filing by any party litigant in
such suit of an undertaking to pay the costs of such suit, and that such court
may in its discretion assess reasonable costs, including reasonable attorneys'
fees, against any party litigant in such suit having due regard to the merits
and good faith of the claim or defenses made by such party litigant; but the
provisions of this Section 515 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 Outstanding Securities of any
series, or, if a series of Securities is held by a Trust, the holders of more
than 10% aggregate liquidation amount of the Preferred Securities of that Trust,
or to any suit instituted by any Holder or holder of Preferred Securities, if
any, for the enforcement of the payment of the principal of or any premium or
Interest on or Additional Amounts with respect to any Security on or after the
respective Stated Maturities expressed in such Security or pursuant to Section
516 (or, in the case of redemption, on or after the Redemption Date, in the case
of repayment, on or after the date for repayment and, in the case of Change of
Control, on or after the date for payment of the Change of Control Purchase
Price) or for the enforcement of the right, if any, to convert or exchange any
Security into Common Stock or other securities, cash or property in accordance
with its terms.

         Section 516. Direct Action Right of Holders of Trust Preferred
Securities.

                  If an Event of Default has occurred and is continuing and is
attributable either to (a) the failure of the Company to pay the principal of or
any premium or Interest on or Additional Amounts with respect to the Securities
on the due date therefor or (b) the failure by the Company to deliver the
required securities or other property upon an appropriate conversion or exchange
right election, and an event of default has occurred and is continuing under the
applicable Trust Agreement, a holder of the related Preferred Securities, in
lieu of any action that may otherwise be taken hereunder as a Holder of
Securities, may institute a legal proceeding directly against the Company for
enforcement of payment to such holder of the principal of or any premium or
Interest on or Additional Amounts with respect to such Securities having a
principal amount equal to the liquidation amount of the Preferred Securities
held by such holder or for enforcement of such conversion or exchange rights, as
the case may be (a "Direct Action"). Notwithstanding anything contained herein
to the contrary, the Company may not

                                       48
<PAGE>

amend this Indenture to remove the foregoing right to bring a Direct Action
without the prior written consent of the holders of all of the Preferred
Securities outstanding affected thereby. Notwithstanding any payments made to a
holder of Preferred Securities by the Company in connection with a Direct
Action, the Company shall remain obligated to pay the principal of and any
premium or Interest on or Additional Amounts with respect to the related
Securities, and the Company shall be subrogated to the rights of the holder of
such Preferred Securities with respect to payments on the Preferred Securities
to the extent of any payments made by the Company to such holder in any Direct
Action.

                                  ARTICLE SIX

         instrument, opinion, report, notice, request, direction, consent,
         order, bond, security, note, coupon or other paper or document

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

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

         thereon;

                  (5) the Trustee shall be under no obligation to exercise any
         of the rights or powers vested in it by or pursuant to this Indenture
         at the request or direction of any of the Holders of Securities of any
         series or any Coupons appertaining thereto pursuant to this Indenture,

                                       49
<PAGE>

                  (6) the Trustee shall not be bound to make any investigation
         into the facts or matters stated in any resolution, certificate,
         statement, instrument, opinion, report, notice, request, direction,
         consent, order, bond, security, 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, during business hours and upon
         reasonable notice, the books, records and promises of the Company,
         personally or by agent or attorney;

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

                  (8) the Trustee shall not be charged with knowledge of any
         default (as defined in Section 602) or Event of Default with respect to
         the Securities of any series for which it is acting as Trustee unless
         either (1) a Responsible Officer of the Trustee assigned to the
         Corporate Trust Department of the Trustee (or any successor division or
         department of the Trustee) shall have actual knowledge of such default
         or Event of Default or (2) written notice of such default or Event of
         Default shall have been given to the Trustee by the Company or any
         other obligor on such Securities or by any Holder of such Securities;

         suffered or omitted by it in good faith and believed by it to be
         authorized or within the discretion or rights or powers conferred upon
         it by this Indenture.

         Section 602. 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 by mail
to all Holders of Securities of such series entitled to receive reports pursuant
to Section 703(3), notice of such default hereunder known to the Trustee, unless
such default shall have been cured or waived; provided, however, that, except in
the case of a default in the payment of the principal of (or premium, if any),
or Interest, if any, on, or Additional Amounts with respect to, any Security of
such series, the Trustee shall be protected in withholding such notice if and so
long as a committee of Responsible Officers of the Trustee in good faith
determines that the withholding of such notice is in the best interest of the
Holders of Securities and Coupons of such series. For the purpose of this
Section, the term "default" means any event which is, or after notice or lapse
of time or both would become, an Event of Default with respect to Securities of
such series.

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

                  The recitals contained herein and in the Securities, except
the Trustee's certificate of authentication, and in any Coupons shall be taken
as the statements of the Company and neither the Trustee nor any Authenticating
Agent assumes any responsibility for their correctness. The Trustee makes no
representations as to the validity or sufficiency of this

                                       50
<PAGE>

Indenture or of the Securities or the Coupons. Neither the Trustee nor any
Authenticating Agent shall be accountable for the use or application by the
Company of the Securities or the proceeds thereof.

         Section 604. May Hold Securities.

                  The Trustee, any Authenticating Agent, any Paying Agent, any
Conversion Agent, any Security Registrar or any other Person that may be an
agent of the Trustee or the Company, in its individual or any other capacity,
may become the owner or pledgee of Securities or Coupons and, subject to
Sections 310(b) and 311 of the Trust Indenture Act, may otherwise deal with the
Company with the same rights it would have if it were not Trustee,
Authenticating Agent, Paying Agent, Conversion Agent, Security Registrar or such
other Person.

         Section 605. Money Held in Trust.

                  Except as provided in Section 403 and Section 1003, money held
by the Trustee in trust hereunder need not be segregated from other funds except
to the extent required by law and shall be held uninvested. The Trustee shall be
under no liability for Interest on any money received by it hereunder except as
otherwise agreed in writing with the Company.

         Section 606. Compensation and Reimbursement.

                  The Company agrees:

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

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

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

                  As security for the performance of the obligations of the
Company under this Section 606, the Trustee shall have a lien prior to the
Securities of any series upon all property and funds held or collected by the
Trustee as such, except funds held in trust for the payment of principal of, and
premium or Interest on or any Additional Amounts with respect to particular
Securities or any Coupons appertaining thereto.

                                       51
<PAGE>

                  Any compensation or expense incurred by the Trustee after a
default specified by Section 501 is intended to constitute an expense of
administration under any then applicable bankruptcy or insolvency law. "Trustee"
for purposes of this Section 606 shall include any predecessor Trustee but the
negligence or bad faith of any Trustee shall not affect the rights of any other
Trustee under this Section 606.

                  The Company's obligations under this Section 606 and any lien
hereunder shall survive the resignation or removal of any Trustee, the discharge
of the Company's obligations pursuant to Article Four of this Indenture and the
termination of this Indenture.

         Section 607. Corporate Trustee Require; Eligibility.

                  (1) There shall at all times be a Trustee hereunder that is a
         Corporation, organized and doing business under the laws of the United
         States of America, any state thereof or the District of Columbia,
         eligible under Section 310(a)(1) of the Trust Indenture Act to act as
         trustee under an indenture qualified under the Trust Indenture Act and
         that has a combined capital and surplus (computed in accordance with
         Section 310(a)(2) of the Trust Indenture Act) of at least $50,000,000
         subject to supervision or examination by Federal or state authority. If
         at any time the Trustee shall cease to be eligible in accordance with
         the provisions of this Section 607, it shall resign immediately in the
         manner and with the effect hereinafter specified in this Article Six.

                  [(2) The following indenture shall be considered specifically
         described herein for purposes of clause (i) of the proviso contained in
         Section 310(b)(1) of the Trust Indenture Act; Indenture dated as of
         between the Company and ______________, as trustee; and, pursuant to
         Section 310(b)(1)(C)(i) of the Trust Indenture Act, unless otherwise
         ordered by the Commission, an event of default by the Company under
         this Indenture will not disqualify the Trustee under this Indenture
         because it is a trustee under such other indenture.]

         Section 608. Resignation and Removal, Appointment of Successor.

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

                  (2) The Trustee may resign at any time with respect to the
         Securities of one or more series by giving written notice thereof to
         the Company. If the instrument of acceptance by a successor Trustee
         required by Section 609 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 with respect to such series.

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

                  (4)      If at any time:

                                       52
<PAGE>

                           (a) the Trustee shall fail to comply with the
                  obligations imposed upon it under Section 310(b) of the Trust
                  Indenture Act with respect to Securities of any series after
                  written request therefor by the Company or any Holder of a
                  Security of such series who has been a bona fide Holder of a
                  Security of such series for at least six months, or

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

                           (c) the Trustee shall become incapable of acting or
                  shall be adjudged 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 with respect to all Securities or
         the Securities of such series, or (ii) subject to Section 315(e) of the
         Trust Indenture Act, 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 removal of the Trustee with respect
         to all Securities of such series and the appointment of a successor
         Trustee or Trustees.

                  (5) 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) and shall comply with the applicable requirements of Section
         609. 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 in accordance with the applicable
         requirements of Section 609, become the successor Trustee with respect
         to the Securities of such series and to that extent supersede the
         successor Trustee appointed by the Company. If no successor Trustee
         with respect to the Securities of any series shall have been so
         appointed by the Company or the Holders of Securities and accepted
         appointment in the manner required by Section 609, 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 the Securities
         of such series.

                  (6) The Company shall give notice of each resignation and each
         removal of the Trustee with respect to the Securities of any series and
         each appointment of a successor Trustee with respect to the Securities
         of any series by mailing written notice of

                                       53
<PAGE>

         such event by first-class mail, postage prepaid, to the Holders of
         Registered Securities, if any, of such series as their names and
         addresses appear in the Security Register and, if Securities of such
         series arc issued as Bearer Securities, by publishing notice of such
         event once in an Authorized Newspaper in each Place of Payment located
         outside the United States. 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.

                  (1) Upon the appointment hereunder of any successor Trustee
         with respect to all Securities, such successor Trustee so appointed
         shall execute, acknowledge and deliver to the Company and the retiring
         Trustee an instrument accepting such appointment, and thereupon the
         resignation or removal of the retiring Trustee shall become effective
         and such successor Trustee, without any further act, deed or
         conveyance, shall become vested with all the rights, trusts and duties
         hereunder of the retiring Trustee; but, on the request of the Company
         or such successor Trustee, such retiring Trustee, upon payment of its
         charges, shall execute and deliver an instrument transferring to such
         successor Trustee all the rights, powers and trusts of the retiring
         Trustee and, subject to Section 1003, 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.

                  (2) Upon the appointment hereunder of any successor Trustee
         with respect to the Securities of one or more (but not all) series, the
         Company, the retiring Trustee and such successor Trustee shall execute
         and deliver an indenture supplemental hereto wherein each successor
         Trustee shall accept such appointment and which (1) shall contain such
         provisions as shall be necessary or desirable to transfer and confirm
         to, and to vest in, such 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, 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
         that no Trustee shall be responsible for any notice given to, or
         received by, or any act or failure to act on the part of any other
         Trustee hereunder, 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, such
         retiring Trustee shall have no further responsibility for the exercise
         of rights and powers or for the performance of the duties and
         obligations vested in the Trustee under this Indenture with respect to
         the Securities of that or those series to which the appointment of such
         successor

                                       54
<PAGE>

         Trustee relates other than as hereinafter expressly set forth, 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 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 such successor Trustee, such retiring
         Trustee, upon payment of its charges with respect to the Securities of
         that or those series to which the appointment of such successor relates
         and subject to Section 1003 shall duly assign, transfer and deliver to
         such successor Trustee, to the extent contemplated by such supplemental
         indenture, the 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, subject to its
         claim, if any, provided for in Section 606.

                  (3) Upon request of any Person appointed hereunder as a
         successor Trustee, the Company shall execute any and all instruments
         for more fully and certainly vesting in and confirming to such
         successor Trustee all such rights, powers and trusts referred to in
         paragraph (1) or (2) of this Section 609, as the case may be.

                  (4) No Person shall accept its appointment hereunder as a
         successor Trustee unless at the time of such acceptance such successor
         Person shall be qualified and eligible under this Article Six.

         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, without the execution or filing of any paper or any further act on
the part of any of the parties hereto. In case any Securities shall have been
authenticated but not delivered by the Trustee then in office, any successor by
merger, conversion or consolidation to such authenticating Trustee may adopt
such authentication and deliver the Securities so authenticated with the same
effect as if such successor Trustee had itself authenticated such Securities.

         Section 611. Appointment of Authenticating Agent.

                  The Trustee may appoint one or more Authenticating Agents
acceptable to the Company with respect to one or more series of Securities which
shall be authorized to act on behalf of the Trustee to authenticate Securities
of that or those series issued upon original issue, exchange, registration of
transfer, partial redemption or partial repayment or pursuant to Section 306,
and Securities so authenticated shall be entitled to the benefits of this
Indenture and shall be valid and obligatory for all purposes as if authenticated
by the Trustee hereunder. Wherever reference is made in this Indenture to the
authentication and delivery of Securities by the Trustee or the Trustee's
certificate of authentication, such reference shall be deemed to include
authentication and delivery on behalf of the Trustee by an Authenticating Agent
and a certificate of authentication executed on behalf of the Trustee by an
Authenticating Agent.

                  Each Authenticating Agent shall be acceptable to the Company
and, except as provided in or pursuant to this Indenture, shall at all times be
a corporation that would be

                                       55

permitted by the Trust Indenture Act to act as trustee under an indenture
qualified under the Trust Indenture Act, is authorized under applicable law and
by its charter to act as an Authenticating Agent and has a combined capital and
surplus (computed in accordance with Section 310(a)(2) of the Trust Indenture
Act) of at least $50,000,000. If at any time an Authenticating Agent shall cease
to be eligible in accordance with the provisions of this Section 611, it shall
resign immediately in the manner and with the effect specified in this Section
611.

                  Any Corporation into which an Authenticating Agent may be
merged or converted or with which it may be consolidated, or any Corporation
resulting from any merger, conversion or consolidation to which such
Authenticating Agent shall be a party, or any Corporation succeeding to all or
substantially all of the corporate agency or corporate trust business of an
Authenticating Agent, shall be the successor of such Authenticating Agent
hereunder, provided such Corporation shall be otherwise eligible under this
Section 611, without the execution or filing of any paper or any further act on
the part of the Trustee or the Authenticating Agent

                  An Authenticating Agent may resign at any time by giving
written notice thereof to the Trustee and the Company. The Trustee may at any
time terminate the agency of an Authenticating Agent by giving written notice
thereof to such Authenticating Agent and 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 611, the Trustee may appoint a successor
Authenticating Agent which shall be acceptable to the Company and shall (i) mail
written notice of such appointment by first-class mail, postage prepaid, to all
Holders of Registered Securities, if any, of the series with respect to which
such Authenticating Agent shall serve, as their names and addresses appear in
the Security Register, and (ii) if Securities of the series are issued as Bearer
Securities, publish notice of such appointment at least once in an Authorized
Newspaper in the place where such successor Authenticating Agent has its
principal office if such office is located outside the United States. Any
successor Authenticating Agent, upon acceptance of its appointment hereunder,
shall become vested with all the rights, powers and duties of its predecessor
hereunder, with like effect as if originally named as an Authenticating Agent.
No successor Authenticating Agent shall be appointed unless eligible under the
provisions of this Section 611.

                  The Company agrees to pay each Authenticating Agent from time
to time reasonable compensation for its services under this Section 611.

                  The provisions of Sections 308, 603 and 604 shall be
applicable to each Authenticating Agent.

                  If an Authenticating Agent is appointed with respect to one or
more series of Securities pursuant to this Section 611, 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 in
substantially the following form:

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

issued at one time, and if the Trustee does not have an office capable of
authenticating Securities upon original issuance located in a Place of Payment
where the Company wishes to have Securities of such series authenticated upon
original issuance, the Trustee, if so requested in writing (which writing need
not be accompanied by or contained in an Officers' Certificate by the Company),
shall appoint in accordance with this Section 611 an Authenticating Agent having
an office in a Place of Payment designated by the Company with respect to such
series of Securities.

         requirements of Section 1404 for quorum or voting; or

                  (3) modify any of the provisions of this Section 902, Section
         513 or Section 1008, except to increase any such percentage or to
         provide that certain other provisions of this Indenture cannot be
         modified or waived without the consent of the Holder of each
         Outstanding Security affected thereby; or

                  (4) make any change that adversely affects the right to
         convert or exchange any Security into or for Common Stock or other
         securities, cash or property in accordance with its terms; or

                  (5) modify any of the provisions of this Indenture relating to
         the subordination of Securities in a manner adverse to the Holders of
         Securities.

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

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

         Section 903. Execution of Supplemental Indentures.

                  As a condition to executing, or accepting the additional
trusts created by, any supplemental indenture permitted by this Article Nine or
the modifications thereby of the trust created by this Indenture, the Trustee
shall be entitled to receive (in addition to those documents

                                       62
<PAGE>

required by Section 102), and (subject to Section 315 of the Trust Indenture
Act) 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. The Trustee may, but shall not be obligated to, enter into any
such supplemental indenture which affects the Trustee's own rights, duties or
immunities under this Indenture or otherwise.

         Section 904. Effect of Supplemental Indentures.

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

         Section 905. Reference in Securities to Supplemental Indentures.

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

         Section 906. Conformity with Trust Indenture Act.

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

         Section 907. Effect on Senior Indebtedness.

                  No supplemental indenture shall directly or indirectly modify
or eliminate the provisions of Article Sixteen in any manner which might
terminate or impair the subordination of the Securities of any series to Senior
Indebtedness with respect to such series without the prior written consent of
the holders of such Senior Indebtedness.

                                  ARTICLE TEN

                                    COVENANTS

         Section 1001. Payment of Principal, any Premium and Interest.

                  (1) The Company shall pay the principal of, any premium and
         Interest on (including Interest accruing during any extension period
         and/or on or after the filing of a petition in bankruptcy or
         reorganization relating to the Company, whether or not a claim for
         post-filing Interest is allowed in such proceeding) and any Additional
         Amounts with respect to the Securities on or prior to the dates and in
         the manner provided in such Securities or pursuant to this Indenture.
         An installment of principal, and any premium,

                                       63
<PAGE>

         Interest or Additional Amounts shall be considered paid on the
         applicable due date if on such date the Trustee or the Paying Agent
         holds, in accordance with this Indenture, money sufficient to pay all
         of such installment then due. With respect to any Security, the Company
         shall pay Interest on overdue principal and Interest on overdue
         installments of Interest (including Interest accruing during any
         extension period and/or on or after the filing of a petition in
         bankruptcy or reorganization relating to the Company, whether or not a
         claim for post-filing Interest is allowed in such proceeding), or
         Additional Amounts to the extent lawful, at the rate accruing on such
         Security, compounded with the same frequency as Interest is payable on
         such Securities. Interest on overdue Interest shall accrue from the
         date such amounts become overdue.

                  (2) Notwithstanding the provisions of Section 1001(1) or any
         other provision herein to the contrary, the Company shall have the
         right, as provided in an Officer's Certificate or supplemental
         indenture issued pursuant to Article Nine, in its sole and absolute
         discretion at any time and from time to time while the Securities of
         any series are outstanding, so long as no Event of Default with respect
         to such series of Securities has occurred and is continuing, to defer
         payments of Interest by extending the Interest payment period for such
         series of Securities for the maximum consecutive period, if any,
         specified for such series of Securities, provided that such extension
         period must end on an Interest Payment Date and shall not extend beyond
         the Stated Maturity or Redemption Date of any Security of such series,
         and provided further that at the end of each extension period the
         Company shall pay all Interest then accrued and unpaid (together with
         Interest thereon to the extent permitted by applicable law at the rate
         accruing on such Securities). Prior to the termination of an extension
         period, the Company may shorten or may further extend the Interest
         payment period for such series of Securities, provided that such
         extension period together with all such previous and further extensions
         may not exceed the maximum consecutive period specified for such series
         of Securities, end on a date other than an Interest Payment Date or
         extend beyond the Stated Maturity or Redemption Date of any Security of
         such series. The Company shall give the Trustee notice of the Company's
         election to begin an extension period for any series of Securities and
         any shortening or extension thereof at least five Business Days prior
         to: (i) the date notice of payment of Interest on such Securities is
         required to be given to any national securities exchange on which the
         related Preferred Securities, if any, or Securities are then listed or
         other applicable self-regulatory organization, or (ii) the date of the
         notice of the record or payment date of the related distribution on the
         Preferred Securities issued by the Trust which is the Holder of the
         Securities of such series, but in any event not less than five Business
         Days prior to the Record Date fixed by the Company for the payment of
         such Interest. The Company shall give or cause the Trustee to give
         notice (a form of which shall be provided by the Company to the
         Trustee) of the Company's election to begin an extension period to the
         Holders by first class mail, postage prepaid.

         Section 1002. Maintenance of Office or Agency.

                  The Company shall maintain in each Place of Payment for any
series of Securities an Office or Agency where Securities of such series (but
not Bearer Securities, except as otherwise provided below, unless such Place of
Payment is located outside the United States) may be presented or surrendered
for payment, where Securities of such series may be

                                       64
<PAGE>

surrendered for registration of transfer or exchange, where Securities of such
series may be presented and surrendered in the event of a conversion or
exchange, and where notices and demands to or upon the Company in respect of the
Securities of such series relating thereto and this Indenture may be served. If
Securities of a series are issuable as Bearer Securities, the Company shall
maintain, subject to any laws or regulations applicable thereto, an Office or
Agency in a Place of Payment for such series which is located outside the United
States where Securities of such series and any Coupons appertaining thereto may
be presented and surrendered for payment; provided, however, that if the
Securities of such series are listed on The Stock Exchange of the United Kingdom
and the Republic of Ireland or the Luxembourg Stock Exchange or any other stock
exchange located outside the United States and such stock exchange shall so
require, the Company shall maintain a Paying Agent and a Conversion Agent, if
applicable, in London, Luxembourg or any other required city located outside the
United States, as the case may be, so long as the Securities of such series are
listed on such exchange. The Company will give prompt written notice to the
Trustee of the location, and any change in the location, of such Office or
Agency. If at any time the Company shall fail to maintain any such required
Office or Agency or shall fail to furnish the Trustee with the addresses
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 such series and any Coupons appertaining thereto may only be
presented and surrendered for payment at the place specified for the purpose
with respect to such Securities as provided in or pursuant to this Indenture,
and the Company hereby appoints the Trustee as its agent to receive all such
presentations, surrenders, notices and demands.

                  Except as otherwise provided in or pursuant to this Indenture,
no payment of principal, premium, Interest or Additional Amounts with respect to
Bearer Securities shall be made at any Office or Agency 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, if
amounts owing with respect to any Bearer Securities shall be payable in Dollars,
payment of principal of, any premium or Interest on and any Additional Amounts
with respect to any such Security may be made at the Corporate Trust Office of
the Trustee or any Office or Agency designated by the Company in the Borough of
Manhattan, The City of New York, if (but only if) payment of the full amount of
such principal, premium, Interest or Additional Amounts at all offices outside
the United States maintained for such purpose by the Company in accordance with
this Indenture is illegal or effectively precluded by exchange controls or other
similar restrictions.

                  The Company may also from time to time designate one or more
other Offices or Agencies where the Securities of one or more series may be
presented or surrendered for any or all such purposes and may from time to time
rescind such 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 each Place of Payment for Securities of any series for
such purposes. The Company shall 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 provided in or pursuant to this
Indenture, the Company hereby designates as the Place of Payment for each series
of Securities the Borough of Manhattan, The City of New York, and initially
appoints the Corporate Trust Office of the Trustee as the Office or Agency of
the Company in the Borough of Manhattan, The City of New York for such purpose.
The Company

                                       65
<PAGE>

may subsequently appoint a different Office or Agency in the Borough of
Manhattan, The City of New York for the Securities of any series.

                  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 this 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 Securities, it shall, on or before each due date
of the principal of, any premium or Interest on or Additional Amounts with
respect to any of the Securities of such series, segregate and hold in trust for
the benefit of the Persons entitled thereto a sum in the 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 of or any premium, Interest or Additional Amounts so
becoming due until such sums shall be paid to such Persons or otherwise disposed
of as herein provided, and shall 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, it shall, on or prior to each due date of the
principal of, any premium or Interest on or any Additional Amounts with respect
to any Securities of such series, deposit with any Paying Agent a sum (in the
Currency or Currencies described in the preceding paragraph) sufficient to pay
the principal of or any premium, Interest or Additional Amounts so becoming due,
such sum to be held in trust for the benefit of the Persons entitled thereto,
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 shall cause each Paying Agent for any series of
Securities other than the Trustee to execute and deliver to the Trustee an
instrument in which such Paying Agent shall agree with the Trustee, subject to
the provisions of this Section 1003, that such Paying Agent shall:

                  (1) hold all sums held by it for the payment of the principal
         of, any premium or Interest on or any Additional Amounts with respect
         to Securities of such series in trust for the benefit of the Persons
         entitled thereto until such sums shall be paid to such Persons or
         otherwise disposed of as provided in or pursuant to this Indenture;

                  (2) give the Trustee notice of any default by the Company (or
         any other obligor upon the Securities of such series) in the making of
         any payment of principal of, any premium or Interest on or any
         Additional Amounts with respect to the Securities of such series; and

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

                                       66
<PAGE>

                  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 a 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 terms 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 herein or pursuant hereto, 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, any premium or Interest
on or any Additional Amounts with respect to any Security of any series or any
Coupon appertaining thereto and remaining unclaimed for two years after such
principal or any such premium or Interest or any such Additional Amount shall
have become due and payable shall be paid to the Company on Company Request, or
(if then held by the Company) shall be discharged from such trust; and the
Holder of such Security or any Coupon appertaining thereto shall thereafter, as
an unsecured general creditor, look only to the Company for payment thereof, and
all liability of the Trustee or such Paying Agent with respect to such trust
money, and all liability of the Company as 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 in each Place of Payment for such
series or to be mailed to Holders of Registered Securities of such series, or
both, 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
or mailing nor shall it be later than two years after such principal and any
premium or Interest or Additional Amounts shall have become due and payable, any
unclaimed balance of such money then remaining will be repaid to the Company.

         Section 1004. Additional Amounts.

                  If any Securities of a series provide for the payment of
Additional Amounts, the Company agrees to pay to the Holder of any such Security
or any Coupon appertaining thereto Additional Amounts as provided in or pursuant
to this Indenture or such Securities. Whenever in this Indenture there is
mentioned, in any context, the payment of the principal of or any premium or
Interest on, or in respect of, any Security of any series or any 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 hereby or pursuant
hereto 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 provision hereof
shall not be construed as excluding Additional Amounts in those provisions
hereof where such express mention is not made.

                  Except as otherwise provided in or pursuant to this Indenture
or the Securities of the applicable series, 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 such series of Securities (or if the
Securities of such series shall not bear Interest prior to Maturity, the first
day on which a payment of principal is made), and at least 10 days prior to each
date of payment of principal or Interest if there has been any change with
respect to the matters set forth in the below-mentioned

                                       67
<PAGE>

Officers' Certificate, the Company shall furnish to the Trustee and the
principal Paying Agent or Paying Agents, if other than the Trustee, an Officers'
Certificate instructing the Trustee and such Paying Agent or Paying Agents
whether such payment of principal of and premium, if any, or Interest on the
Securities of such series shall be made to Holders of Securities of such series
or the Coupons appertaining thereto who are United States Aliens without
withholding for or on account of any tax, assessment or other governmental
charge described in the Securities of such 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 or Coupons, and the Company agrees to pay to the Trustee or such
Paying Agent the Additional Amounts required by the terms of such Securities.
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 1004.

         Section 1005. No Restriction on Indebtedness or Liens.

                  Nothing in this Indenture or in the Securities shall in any
way restrict or prevent the Company or any Subsidiary from issuing, assuming,
guaranteeing or otherwise incurring or securing any Indebtedness, or otherwise
granting any Liens in respect thereof.

                  For purposes of this Section 1005, "Lien" shall mean, with
respect to any asset, any mortgage, lien, pledge, security interest or
encumbrances of any kind in respect of such asset, whether or not filed,
recorded or otherwise perfected under applicable law.

         Section 1006. Corporate Existence.

                  Subject to Articles Eight and Fifteen, the Company shall do or
cause to be done all things necessary to preserve and keep in full force and
effect its corporate existence and that of each Subsidiary and their respective
rights (charter and statutory) and franchises; provided, however, that the
foregoing shall not obligate the Company or any Subsidiary to preserve any such
right or franchise if the Company or any Subsidiary shall determine that the
preservation thereof is no longer desirable in the conduct of its business or
the business of such Subsidiary.

         Section 1007. Payment of Expenses of Each Trust.

                  The Company covenants for the benefit of the Holders of each
series of Securities owned by a Trust to pay all of the obligations, costs and
expenses of such Trust (other than payments in respect of Trust Securities) in
accordance with the provisions of its Trust Agreement and to pay the taxes of
such Trust in accordance with the provisions of its Trust Agreement in order to
permit such Trust to make distributions on and redemptions of its Preferred
Securities in accordance with its Trust Agreement.

         Section 1008. Waiver of Certain Covenants.

                  The Company may omit in any particular instance to comply with
any term, provision or condition set forth in Sections 1001(2) or 1006 with
respect to the Securities of any series if before the time for such compliance
the Holders of at least a majority in principal

                                       68
<PAGE>

amount of the Outstanding Securities of such series, by Act of such Holders,
either shall waive such compliance in such instance or generally shall have
waived compliance with such term, provision or condition, but no such waiver
shall extend to or affect such term, provision 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.

         Section 1009. Company Statement as to Compliance; Notice of Certain
Defaults.

                  (1) The Company shall deliver to the Trustee, within 120 days
         after the end of each fiscal year, a written statement (which need not
         be contained in or accompanied by an Officers' Certificate) signed by
         the principal executive officer, the principal financial officer or the
         principal accounting officer of the Company, stating that:

                           (a) a review of the activities of the Company during
                  such year and of its performance under this Indenture has been
                  made under his or her supervision; and

                           (b) to the best of his or her knowledge, based on
                  such review, (i) the Company has complied with all the
                  conditions and covenants imposed on it under this Indenture
                  throughout such year, or, if there has been a default in the
                  fulfillment of any such condition or covenant, specifying each
                  such default known to him or her and the nature and status
                  thereof, and (ii) no event has occurred and is continuing
                  which is, or after notice or lapse of time or both would
                  become, an Event of Default, or, if such an event has occurred
                  and is continuing, specifying each such event known to him and
                  the nature and status thereof.

                  (2) the Company shall deliver to the Trustee, within five days
         after the occurrence thereof, written notice of any Event of Default or
         any Default.

                                 ARTICLE ELEVEN

                            REDEMPTION OF SECURITIES

         Section 1101. Applicability of Article.

                  Redemption of Securities of any series at the option of the
Company as permitted or required by the terms of such Securities shall be made
in accordance with the terms of such Securities and (except as otherwise
provided herein or pursuant hereto) this Article Eleven.

         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 or an Officers' Certificate. In
case of any redemption at the election of the Company of (a) less than all of
the Securities of any series or (b) all of the Securities of any series, with
the same issue date, Interest rate or formula, Stated Maturity and other terms,
the Company shall, at least 60 days prior to the Redemption Date fixed by the
Company (unless a shorter notice shall be satisfactory to the Trustee), notify
the Trustee of such Redemption Date and of the principal amount of Securities of
such series to be redeemed.

<PAGE>

         Section 1103. Selection by Trustee of Securities to be Redeemed.

                  If less than all of the Securities of any series with the same
issue date, Interest rate or formula, Stated Maturity and other 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 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 of the principal amount of Registered
Securities of such series; provided, however, that no such partial redemption
shall reduce the portion of the principal amount of a Registered Security of
such series not redeemed to less than the minimum denomination for a Security of
such series established herein or pursuant hereto.

                  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 Securities redeemed or to be redeemed only in
part, to the portion of the principal of such Securities which has been or is to
be redeemed.

                  Unless otherwise specified in or pursuant to this Indenture or
the Securities of any series, if any Security selected for partial redemption is
converted or exchanged for Common Stock or other securities, cash or property in
part before termination of the conversion or exchange right with respect to the
portion of the Security so selected, the converted or exchanged portion of such
Security shall be deemed (so far as may be) to be the portion selected for
redemption. Securities which have been converted or exchanged during a selection
of Securities to be redeemed shall be treated by the Trustee as Outstanding for
the purpose of such selection.

         Section 1104. Notice of Redemption.

                  Notice of redemption shall be given in the manner provided in
Section 106, not less than 30 nor more than 60 days prior to the Redemption
Date, unless a shorter period is specified in the Securities to be redeemed, to
the Holders of Securities to be redeemed. Failure to give notice by mailing in
the manner herein provided to the Holder of any Registered Securities 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 Securities or portion thereof.

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

                  All notices of redemption shall state:

                  (1) the Redemption Date;

                  (2) the Redemption Price;

                                       70
<PAGE>

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

                  (4) in case any Security is to be redeemed in part only, the
         notice which relates to such Security shall state that on and after the
         Redemption Date, upon surrender of such Security, the Holder of such
         Security will receive, without 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 shall
         become due and payable upon each such Security or 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 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 any accrued Interest and Additional
         Amounts pertaining thereto;

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

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

                  (9) that the redemption is out of a sinking fund, if such is
         the case;

                  (10) in the case of Securities of any series that are
         convertible or exchangeable into other securities, cash or property or
         rights, the conversion or exchange price or rate, the date or dates on
         which or the period or periods during which the right to convert or
         exchange the principal of the Securities of such series to be redeemed
         will commence or terminate and the place or places where such
         Securities may be surrendered for conversion or exchange; and

                  (11) the CUSIP number or the Euroclear or the Clearstream
         Luxembourg reference numbers of such Securities, if any (or any other
         numbers used by a Depository to identify such Securities).

                  A notice of redemption mailed as contemplated by Section 106
need not identify particular Registered Securities to be redeemed.

                                       71
<PAGE>

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

         Section 1105. Deposit of Redemption Price.

                  On or prior to 10:00 a.m., New York City time, on any
Redemption Date, the Company shall deposit, with respect to the Securities of
any series called for redemption pursuant to Section 1104, 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 applicable Currency sufficient to pay the Redemption Price of, and (except
if the Redemption Date shall be an Interest Payment Date, unless otherwise
specified pursuant to Section 301 or in the Securities of such series) any
accrued Interest on and Additional Amounts with respect thereto, all such
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, and from and after such date
(unless the Company shall default in the payment of the Redemption Price and
accrued Interest) such Securities shall cease to bear Interest 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 any
accrued Interest and Additional Amounts to the Redemption Date; provided,
however, that, except as otherwise provided in or pursuant to this Indenture or
the Bearer Securities of such series, installments of Interest on Bearer
Securities whose Stated Maturity is on or prior to the Redemption Date shall be
payable only upon presentation and surrender of Coupons for such Interest (at an
Office or Agency located outside the United States except as otherwise provided
in Section 1002), and provided, further, that, except as otherwise specified in
or pursuant to this Indenture or the Registered Securities of such series,
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 Regular Record Dates therefor 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 any Interest or Additional Amounts

                                       72
<PAGE>

represented by Coupons shall be payable only upon presentation and surrender of
those Coupons at an Office or Agency for such Security located outside of the
United States except as otherwise provided in Section 1002.

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

         Section 1107. Securities Redeemed in Part.

                  Any Registered Security which is to be redeemed only in part
shall be surrendered at any Office or Agency for such Security (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 Registered Security or
Securities of the same series, containing identical terms and provisions, of any
authorized denomination as requested by such Holder in aggregate principal
amount equal to and in exchange for the unredeemed portion of the principal of
the Security so surrendered. If a Security in global form is so surrendered, the
Company shall execute, and the Trustee shall authenticate and deliver to the
U.S. Depository or other Depository for such Security in global form as shall be
specified in the Company Order with respect thereto to the Trustee, without
service charge, a new Security in global form in a denomination equal to and in
exchange for the unredeemed portion of the principal of the Security in global
form so surrendered.

                       REPAYMENT AT THE OPTION OF HOLDERS

         Section 1201. Applicability of Article.

                  Securities of any series which are repayable at the option of
the Holders thereof before their Stated Maturity shall be repaid in accordance
with the terms of the Securities of such series. The repayment of any principal
amount of Securities pursuant to such option of the Holder to require repayment
of Securities before their Stated Maturity, for purposes of Section 309, shall
not operate as a payment, redemption or satisfaction of the Indebtedness
represented by such Securities unless and until the Company, at its option,
shall deliver or surrender the same to the Trustee with a directive that such
Securities be cancelled. Notwithstanding anything to the contrary contained in
this Section 1201, in connection with any repayment of Securities, the Company
may arrange for the purchase of any Securities by an agreement with one or more
investment bankers or other purchasers to purchase such Securities by paying to
the Holders of such Securities on or before the close of business on the
repayment date an amount not less than the repayment price payable by the
Company on repayment of such Securities, and the obligation of the Company to
pay the repayment price of such Securities shall be satisfied and discharged to
the extent such payment is so paid by such purchasers.

                        SECURITIES IN FOREIGN CURRENCIES

         Section 1301. Applicability of Article.

                  Whenever this Indenture provides for (i) any action by, or the
determination of any of the rights of, Holders of Securities of any series in
which not all of such Securities are denominated in the same Currency, or (ii)
any distribution to Holders of Securities, in the absence of any provision to
the contrary in the form of Security of any particular series or pursuant to
this Indenture or the Securities, any amount in respect of any Security
denominated in a Currency other than Dollars shall be treated for any such
action or distribution as that amount of Dollars that could be obtained for such
amount on such reasonable basis of exchange and as of the record date with
respect to Registered Securities of such series (if any) for such action,
determination of rights or distribution (or, if there shall be no applicable
record date, such other date reasonably proximate to the date of such action,
determination of rights or distribution) as the Company may specify in a written
notice to the Trustee or, in the absence of such written notice, as the Trustee
may determine.

         City of New York, or, if Securities of such series have been issued in
         whole or in part as Bearer Securities, in London or in such place
         outside the United States as the Trustee shall determine. Notice of
         every meeting of Holders of Securities of any series, setting forth the

         proposed to be taken at such meeting, shall be given in the manner
         provided in Section 106 not less than 21 nor more than 180 days prior

                  (2) In case at any time the Company (by or pursuant to a Board
         Resolution) or the Holders of at least 10% in principal amount of the
         Outstanding Securities of any series shall have requested the Trustee
         to call a meeting of the Holders of Securities of such series for any

                                       74
<PAGE>

         21 days after receipt of such request (whichever shall be required
         pursuant to Section 106) or shall not thereafter proceed to cause the

         of Securities of such series in the amount above specified, as the case
         may be, may determine the time and the place in the Borough of
         Manhattan, The City of New York, or, if Securities of such series are
         to be issued as Bearer Securities, in London for such meeting and may
         call such meeting for such purposes by giving notice thereof as

the Outstanding Securities of a series shall constitute a quorum for a meeting

is to be taken at such meeting with respect to a consent or waiver which this
Indenture expressly provides may be given by the Holders of at least 66-2/3% in
principal amount of the Outstanding Securities of a series, the Persons entitled
to vote 66-2/3% in principal amount of the Outstanding Securities of such series
shall constitute a quorum. In the absence of a quorum within 30 minutes after
the time appointed for any such meeting, the meeting shall, if convened at the
request of Holders of Securities of such series, be dissolved. In any other
case, the meeting may be adjourned for a period of not less than 10 days as
determined by the chairman of the meeting prior to the adjournment of such
meeting. In the absence of a quorum at any such adjourned meeting, such
adjourned meeting may be further adjourned for a period of not less than 10 days
as determined by the chairman of the meeting prior to the adjournment of such
adjourned meeting. Notice of the reconvening of any adjourned meeting shall be

                  Except as limited by the proviso to Section 902, any
resolution presented to a meeting or adjourned meeting duly reconvened at which
a quorum is present as aforesaid may be adopted only by the affirmative vote of
the Holders of a majority in principal amount of the Outstanding Securities of
that series; provided, however, that, except as limited by the proviso to
Section 902, any resolution with respect to any consent or waiver which this
Indenture expressly provides may be given by the Holders of at least 66-2/3% in
principal amount of the Outstanding Securities of a series may be adopted at a
meeting or an adjourned meeting duly convened and at which a quorum is present
as aforesaid only by the affirmative vote of the Holders of 66-2/3% in

<PAGE>

principal amount of the Outstanding Securities of that series; and provided,
further, that, except as limited by the proviso to Section 902, any resolution
with respect to any request, demand, authorization, direction, notice, consent,
waiver or other Act which this Indenture expressly provides may be made, given
or taken by the Holders of a specified percentage, which is less than a
majority, in principal amount of the Outstanding Securities of a series may be
adopted at a meeting or an adjourned meeting duly reconvened and at which a
quorum is present as aforesaid by the affirmative vote of the Holders of such
specified percentage in principal amount of the Outstanding Securities of such
series.

                  Any resolution passed or decision taken at any meeting of
Holders of Securities of any series duly held in accordance with this Section
1404 shall be binding on all the Holders of Securities of such series and the
Coupons appertaining thereto, whether or not such Holders were present or
represented at the meeting.

         Section 1405. Determination of Voting Rights, Conduct and Adjournment
of Meetings.

                  (1) Notwithstanding any other provisions of this Indenture,
         the Trustee may make such reasonable regulations as it may deem
         advisable for any meeting of Holders of Securities of such 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.

                  (2) 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 1402(2), in which case the Company or the Holders of Securities
         of the series calling the meeting, as the case may be, shall in like
         manner appoint a temporary chairman. A permanent chairman and a
         permanent secretary of the meeting shall be elected by vote of the
         Persons entitled to vote a majority in principal amount of the
         Outstanding Securities of such series represented at the meeting.

                  (3) At any meeting, each Holder of a Security of such series
         or proxy shall be entitled to one vote for each $1,000 principal amount
         of 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.

<PAGE>

                  (4) Any meeting of Holders of Securities of any series duly
         called pursuant to Section 1402 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 1406. 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
triplicate, 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 facts setting forth a copy of the notice of the meeting and
showing that said notice was given as provided in Section 1402 and, if
applicable, Section 1404. 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.

                  outstanding immediately prior to the consummation of such
                  consolidation or merger are converted into cash, securities or

                  indirectly, (A) 75% or more of the common stock of the sole

         an Authorized Newspaper in such city as the stock exchange so requires.
         The notice shall include or transmit a form of Change in Control

                  Office or Agency;

                           (f) that the Securities must be surrendered to the
                  Trustee or the Office or Agency to collect payment;

                           (g) that the Change in Control Purchase Price for any
                  Security as to which a Change in Control Purchase Notice has
                  been duly given and not withdrawn will be paid promptly
                  following the later of the Change in Control Purchase Date or
                  the time of surrender of such Security as described in Section
                  1501(2)(f);

                  (3) A Holder may exercise its rights specified in Section

         Control Purchase Notice") to the Trustee or to the Office or Agency at
         any time prior to the close of business of the Change in Control
         Purchase Date, stating:

                           (a) the certificate number or numbers of the Security
                  or Securities, except in the case of global Securities, which
                  the Holder will deliver to be purchased;

                           (b) the portion of the principal amount of the

                  purchased, which portion must be $1,000 or an integral
                  multiple thereof; and

                           (c) that such Security or Securities shall be

<PAGE>

                  The delivery of the Security, by hand or by registered mail
prior to, on or after the Change in Control Purchase Date (together with all
necessary endorsements), to the Trustee or to the Office or Agency shall be a
condition precedent to the obligation of the Company to pay to the Holder the
Change in Control Purchase Price therefor; provided, however, that such Change
in Control Purchase Price shall be so paid pursuant to this Section 1501 only if
the Security so delivered to the Trustee or such Office or Agency shall conform
in all respects to the description thereof set forth in the related Change in
Control Purchase Notice.

                  Notwithstanding anything herein to the contrary, any Holder
delivering to the Trustee or to the Office or Agency, the Change in Control
Purchase Notice contemplated by this Section 1501(3) shall have the right to
withdraw such Change in Control Purchase Notice at any time prior to or on the
Change in Control Purchase Date by delivery of a written notice of withdrawal to
the Trustee or to such office or agency in accordance with Section 1502.

         Section 1502. Effect of Change in Control Purchase Notice.

                  Upon receipt by the Company of the Change in Control Purchase
Notice specified in Section 1501(3), the Holder of the Security in respect of
which such Change in Control Purchase Notice was given shall (unless such Change
in Control Purchase Notice is withdrawn as specified in the following paragraph)
thereafter be entitled to receive solely the Change in Control Purchase Price
with respect to such Security. Such Change in Control Purchase Price shall be
paid to such Holder promptly following the later of (x) the Change in Control
Purchase Date, as the case may be, with respect to such Security (provided the
conditions in Section 1501(3), as applicable, have been satisfied) and (y) the
time of delivery of such Security to the Trustee or to the Office or Agency by
the Holder thereof in the manner required by Section 1501(3) as applicable.

                  A Change in Control Purchase Notice may be withdrawn by means
of a written notice of withdrawal delivered to the office of the Trustee or to
the Office or Agency at any time prior to the close of business on the Change in
Control Purchase Date, specifying:

                  (1) the certificate number or numbers of the Security or
         Securities, except in the case of global Securities, in respect of
         which such notice of withdrawal is being submitted;

                  (2) the principal amount of the Security or Securities with
         respect to which such notice of withdrawal is being submitted, and

                  (3) the principal amount, if any, of such Security or
         Securities which remains subject to the original Change in Control
         Purchase Notice, and which has been and will be delivered for purchase
         by the Company.

                  There shall be no purchase of any Securities pursuant to
Section 1501 if there has occurred and is continuing an Event of Default (other
than a default in the payment of the Change in Control Purchase Price).

         Section 1503. Deposit of Change in Control Purchase Price.

                  Prior to 12:00 Noon (local time in The City of New York) on
the Business Day following the Change in Control Purchase Date, the Company
shall deposit with the Trustee (or, if the Company or a Subsidiary or an
Affiliate of either of them is acting as Paying Agent, shall segregate and hold
in trust as provided in Section 1003) an amount of cash in immediately available
funds or securities, if expressly permitted hereunder, sufficient to pay the
aggregate Change in Control Purchase Price of all the Securities or portions
thereof which are to be purchased. If a deposit is made with the Trustee of the
aforesaid amount of cash or securities, the Securities or portions thereof with
respect to which a Change in Control Purchase Notice has been delivered and not
validly withdrawn shall become due and payable as of the Business Day following
the applicable Change in Control Purchase Date, and on and after such date
Interest payable in respect of such Securities shall cease and all other rights
of the Holders thereof shall terminate, other than the right to receive the
Change in Control Purchase Price upon delivery of such Securities to the
Trustee.

         Section 1504. Covenant to Comply With Securities Laws Upon Purchase of
Securities.

                  In connection with any purchase of Securities under Section
1501 hereof, the Company shall (a) comply with Rule 13e-4 under the Exchange Act
of 1934, if applicable, (b) file the related Schedule 13E-4 (or any successor
schedule, form or report) under the Securities Exchange Act of 1934, if
applicable, and (c) otherwise comply with all Federal and state securities laws
regulating the purchase of the Securities (including positions of the Commission
under applicable no-action letters) so as to permit the rights and obligation
under Section 1501 to be exercised in the time and in the manner specified in
Section 1501 and 1502.

         Section 1505. Repayment to the Company.

                  The Trustee shall return to the Company any cash, together
with Interest or dividends, if any, thereon (subject to the provisions of
Section 605) held by it for the payment of the Change in Control Purchase Price
of the Securities that remain unclaimed as provided in the Securities; provided,
however, that to the extent the aggregate amount of cash deposited by the
Company pursuant to Section 1503 exceeds the aggregate Change in Control
Purchase Price of the Securities or portions thereof to be purchased, then
promptly after the Change in Control Purchase Date, the Trustee shall return any
such excess to the Company together with Interest or dividends, if any, thereon
(subject to the provisions of Section 605).

                                ARTICLE SIXTEEN

                                  SUBORDINATION

         Section 1601. Securities Subordinated to Senior Indebtedness.

                  Notwithstanding the provisions of Section 506 or any other
provision herein or in any Security, the Company and the Trustee and, by their
acceptance thereof, the Holders of the Securities (a) covenant and agree that
all payments by the Company of the principal of and any premium or Interest on

supplemental indenture establishing the series as to which such sinking fund is
applicable) shall be subordinated in accordance with the provisions of this
Article Sixteen in right of payment to the prior payment in full, in cash or
cash equivalents, of all amounts payable on, under or in connection with Senior
Indebtedness, and (b) acknowledge that holders of Senior Indebtedness are or
shall be relying on this Article Sixteen. Nothing herein or in any Security is
intended to or shall limit the amount of Senior Indebtedness the Company may
incur.

         Section 1602. Priority and Payment of Proceeds in Certain Events:
Remedies Standstill.

                  (1) Upon any payment or distribution of assets or securities
         of the Company, as the case may be, of any kind or character, whether
         in cash, property or securities, upon any dissolution or winding up or
         total or partial liquidation or reorganization of the Company, whether
         voluntary or involuntary, or in bankruptcy, insolvency, receivership or
         other proceedings, all amounts payable on, under or in connection with
         Senior Indebtedness (including any Interest accruing on such Senior
         Indebtedness subsequent to the commencement of a bankruptcy,
         insolvency, receivership or similar proceeding) shall first be paid,
         ratably according to the aggregate amounts remaining unpaid on account
         of the principal of and any premium and Interest on the Senior
         Indebtedness held or represented by each, to the extent necessary to
         make payment in full of all Senior Indebtedness remaining unpaid, in
         cash, or payment provided for in cash or cash equivalents, ratably
         according to the aggregate amounts remaining unpaid on account of the
         principal of and any premium and Interest on the Senior Indebtedness
         held or represented by each, to the extent necessary to make payment in
         full of all Senior Indebtedness remaining unpaid, before the Holders or
         the Trustee on behalf of the Holders or the holders of Preferred
         Securities, if any, shall be entitled to receive from the Company any
         payment of principal of or any premium or Interest on or Additional
         Amounts with respect to the Securities or distribution of any assets or
         securities.

                  (2) No direct or indirect payment by or on behalf of the
         Company of principal of or any premium or Interest on or Additional
         Amounts with respect to the Securities (other than Securities which
         have been discharged pursuant to Article Four or Securities that
         provide for a sinking fund), whether pursuant to the terms of the
         Securities or upon acceleration or otherwise, shall be made if, at the
         time of such payment, there exists (a) a default in the payment of all
         or any portion of any Senior Indebtedness and the Trustee has received
         written notice thereof from the Company, from holders of Senior
         Indebtedness or from any trustee, representative or agent therefor, or
         (b) any other default affecting Senior Indebtedness as a result of
         which the maturity of Senior Indebtedness has been accelerated and the
         Trustee has received written notice from the Company, from holders of
         Senior Indebtedness or from any trustee, representative or agent
         therefor, and such default shall not have been cured or waived by or on
         behalf of the holders of such Senior Indebtedness.

                  (3) If, notwithstanding the foregoing provisions prohibiting
         such payment or distribution, the Trustee or any Holder shall have
         received any payment on account of the principal of or any premium or
         Interest on or Additional Amounts with respect to the Securities when
         such payment is prohibited by this Section 1602 and before all amounts

                                       82
<PAGE>

         payable on, under or in connection with Senior Indebtedness are paid in
         full in cash or cash equivalents, then and in such event (subject to
         the provisions of Section 1608) such payment or distribution shall be
         received and held in trust for the holders of Senior Indebtedness and,
         at the written direction of the trustee, representative or agent for
         the holders of the Senior Indebtedness, shall be paid to the holders of
         the Senior Indebtedness remaining unpaid to the extent necessary to pay
         such Senior Indebtedness in full in cash or cash equivalents.

                  Upon any payment or distribution of assets or securities
referred to in this Article Sixteen, the Trustee and the Holders shall be
entitled to rely upon any order or decree of a court of competent jurisdiction
in which such dissolution, winding up, liquidation or reorganization proceedings
are pending or upon a certificate of the receiver, trustee in bankruptcy,
liquidating trustee, agent or other Person making any such payment or
distribution, delivered to the Trustee or to the Holders for the purpose of
ascertaining the Persons entitled to participate in such distribution, the
holders of Senior Indebtedness and other Indebtedness of the Company, the amount
thereof or payable thereon, the amount or amounts paid or distributed thereon
and all other facts pertinent thereto or to this Article Sixteen.

         Section 1603. Payments which May Be Made Prior to Notice.

                  Nothing in this Article Sixteen or elsewhere in this Indenture
shall prevent (1) the Company, except under the conditions described in Section
1602, from making payments of principal of or any premium or Interest on or
Additional Amounts with respect to the Securities or from depositing with the
Trustee any monies for such payments, or (2) the application by the Trustee of
any monies deposited with it for the purpose of making such payments of
principal of or any premium or Interest on or Additional Amounts with respect to
the Securities, to the Holders entitled thereto, unless at least two Business
Days prior to the date when such payment would otherwise (except for the
prohibitions contained in Section 1602) become due and payable, the Trustee
shall have received the written notice provided for in Section 1602(2)(a) or
(b).

         Section 1604. Rights of Holders of Senior Indebtedness Not to Be
Impaired.

                  No right of any present or future holder of any Senior
Indebtedness to enforce subordination as herein provided shall at any time or in
any way be prejudiced or impaired by any act or failure to act in good faith by
any such holder, or by any noncompliance by the Company with the terms and
provisions and covenants herein regardless of any knowledge thereof any such
holder may have or otherwise be charged with.

                  The provisions of this Article Sixteen are intended to be for
the benefit of, and shall be enforceable directly by, the holders of Senior
Indebtedness. Notwithstanding anything to the contrary in this Article Sixteen,
to the extent any Holders or the Trustee have paid over or delivered to any
holder of Senior Indebtedness any payment or distribution received on account of
the principal of or any premium or Interest on or Additional Amounts with
respect to the Securities to which any other holder of Senior Indebtedness shall
be entitled to share in accordance with Section 1602, no holder of Senior
Indebtedness shall have a claim or right

                                       83
<PAGE>

against any Holders or the Trustee with respect to any such payment or
distribution or as a result of the failure to make payments or distributions to
such other holder of Senior Indebtedness.

         Section 1605. Trustee May Take Action to Effectuate Subordination.

                  Each Holder of a Security, by his acceptance thereof,
authorizes and directs the Trustee on his behalf to take such action as may be
required by the trustee, representative or agent for holders of Senior
Indebtedness or by the Company to effectuate, as between the holders of Senior
Indebtedness and the Holders, the subordination as provided in this Article
Sixteen and appoints the Trustee his attorney-in-fact for any and all such
purposes.

         Section 1606. Subrogation.

                  Upon the payment in full, in cash or cash equivalents, of all
Senior Indebtedness, any Holder shall be subrogated to the rights of the holders
of such Senior Indebtedness to receive payments or distributions of assets of
the Company in respect of such Senior Indebtedness until the Securities shall be
paid in full; and for the purposes of such subrogation, no payments or
distributions to holders of such Senior Indebtedness of any cash property or
securities to which such Holders of the Securities would be entitled except for
this Article Sixteen, and no payment pursuant to this Article Sixteen to holders
of such Senior Indebtedness by such Holders of the Securities, shall, as between
the Company, its creditors other than holders of such Senior Indebtedness and
such Holders of the Securities, be deemed to be a payment by the Company to or
on account of such Senior Indebtedness, it being understood that the provisions
of this Article Sixteen are solely for the purpose of defining the relative
rights of the holders of such Senior Indebtedness, on the one hand, and such
Holders of the Securities, on the other hand.

                  If any payment or distribution to which Holders of Securities
would otherwise have been entitled but for the provisions of this Article
Sixteen shall have been applied, pursuant to this Article Sixteen, to the
payment of all Senior Indebtedness, then and in such case such Holders of the
Securities shall be entitled to receive from the holders of such Senior
Indebtedness at the time outstanding any payments or distributions received by
such holders of Senior Indebtedness in excess of the amount sufficient to pay,
in cash or cash equivalents, all such Senior Indebtedness in full.

         Section 1607. Obligations of Company Unconditional; Reinstatement.

                  Nothing in this Article Sixteen or elsewhere in this Indenture
or in any Security is intended to or shall impair, as among the Company, its
creditors other than holders of Senior Indebtedness and Holders of the
Securities, the obligations of the Company, which are absolute and
unconditional, to pay to such Holders the principal of and any premium and
Interest on and Additional Amounts with respect to the Securities as and when
the same shall become due and payable in accordance with their terms, or is
intended to or shall affect the relative rights of such Holders of the
Securities and creditors of the Company other than the holders of the Senior
Indebtedness, nor shall anything herein or therein prevent the Trustee or any
Holder of Securities or holder of Preferred Securities, as applicable, from
exercising all remedies otherwise permitted by applicable law under this
Indenture, subject to the rights, if any, under this Article Sixteen of

                                       84
<PAGE>

the holders of such Senior Indebtedness in respect of cash, property or
securities of the Company received upon the exercise of any such remedy.

                  The failure to make a scheduled payment of principal of or any
premium or Interest on or Additional Amounts with respect to the Securities by
reason of Section 1602 shall not be construed as preventing the occurrence of a
Default or an Event of Default under Section 501; provided, however, that if (1)
the conditions preventing the making of such payment no longer exist, and (2)
such Holders of the Securities are made whole with respect to such omitted
payments, the Default or Event of Default relating thereto (including any
failure to pay any accelerated amounts) shall be automatically waived, and the
provisions of the Indenture shall be reinstated as if no such Event of Default
had occurred.

         Section 1608. Trustee Entitled to Assume Payments Not Prohibited in
Absence of Notice.

                  The Trustee or Paying Agent shall not be charged with the
knowledge of the existence of any default in the payment of all or a portion of
any Senior Indebtedness or any other default affecting Senior Indebtedness as a
result of which the maturity of the Senior Indebtedness has been accelerated,
unless and until the Trustee or Paying Agent shall have received written notice
thereof from the Company or one or more holders of Senior Indebtedness or from
any trustee, representative or agent therefor; and, prior to the receipt of any
such written notice, the Trustee or Paying Agent may conclusively assume that no
such facts exist.

                  Unless at least two Business Days prior to the date when by
the terms of this Indenture any monies are to be deposited by the Company with
the Trustee or any Paying Agent for any purpose (including, without limitation,
the payment of the principal of or any premium or Interest on or Additional
Amounts with respect to any Security), the Trustee or Paying Agent shall have
received with respect to such monies the notice provided for in Section 1602,
the Trustee or Paying Agent shall have full power and authority to receive and
apply such monies to the purpose for which they were received. Neither of them
shall be affected by any notice to the contrary, which may be received by either
on or after such second Business Day. The foregoing shall not apply to the
Paying Agent if the Company is acting as Paying Agent. Nothing in this Section
1608 shall limit the right of the holders of Senior Indebtedness to recover
payments as contemplated by Section 1602. The Trustee or Paying Agent shall be
entitled to rely on the delivery to it of a written notice by a Person
representing himself or itself to be a holder of such Senior Indebtedness (or a
trustee, representative or agent on behalf of such holder) to establish that
such notice has been given by a holder of such Senior Indebtedness or a trustee,
representative or agent on behalf of any such holder. The Trustee shall not be
deemed to have any fiduciary duty to the holders (and shall be fully protected
in relying upon such notice) of Senior Indebtedness.

         Section 1609. Right of Trustee to Hold Senior Indebtedness.

                  The Trustee and any Paying Agent shall be entitled to all of
the rights set forth in this Article Sixteen in respect of any Senior
Indebtedness at any time held by them, to the same extent as any other holder of
such Senior Indebtedness, and nothing in this Indenture shall be construed to
deprive the Trustee or any Paying Agent of any of its rights as such holder.

         Section 1610. Notice to Trustee.

                  The Company shall give prompt written notice to the Trustee or
Paying Agent of any fact known to the Company which would prohibit the making of
any payment to or by the Trustee in respect of the Securities. Failure to give
such notice shall not affect the subordination of the Securities to Senior
Indebtedness. Notwithstanding the provisions of this or any other provision of
this Indenture, the Trustee or Paying Agent shall not be charged with knowledge
of the existence of any facts which would prohibit the making of any payment to
or by the Trustee or Paying Agent in respect of the Securities pursuant to this
Article Sixteen, unless and until the Trustee or Paying Agent shall have
received written notice from the Company or a holder of Senior Indebtedness or
from any trustee or agent therefor; and, prior to the receipt of any such
written notice, the Trustee, subject to the provisions of Section 601, or Paying
Agent shall be entitled in all respects to assume that no such facts exist;
provided, however, that if a Responsible Officer of the Trustee or Paying Agent
shall not have received, at least three Business Days prior to the date upon
which by the terms hereof any such money may become payable for any purpose
(including, without limitation, the payment of the principal of or any premium
or Interest on or Additional Amounts with respect to any Security, the notice
with respect to such money provided for in this Section 1610, then, anything
herein contained to the contrary notwithstanding, the Trustee or Paying Agent
shall have full power and authority to receive such money and to apply the same
to the purpose for which such money was received and shall not be affected by
any notice to the contrary which may be received by it within three Business
Days prior to such date.

                  The Trustee, subject to the provisions of Section 601, or
Paying Agent shall be entitled to conclusively rely on the delivery to it of a
written notice by a Person representing himself or itself to be a holder of
Senior Indebtedness (or a trustee or agent on behalf of such holder) to
establish that such notice has been given by a holder of Senior Indebtedness (or
a trustee or agent on behalf of any such holder). In the event that the Trustee
or Paying Agent determines in good faith that further evidence is required with
respect to the right of any Person as a holder of Senior Indebtedness to
participate in any payment or distribution pursuant to this Article Sixteen, the
Trustee or Paying Agent may request such Person to furnish evidence to the
reasonable satisfaction of the Trustee or Paying Agent as to the amount of
Senior Indebtedness held by such Person, the extent to which such Person is
entitled to participate in such payment or distribution and any other facts
pertinent to the rights of such Person under this Article Sixteen, and if such
evidence is not furnished, the Trustee or Paying Agent may defer any payment
which it may be required to make for the benefit of such Person pursuant to the
terms of this Indenture pending judicial determination as to the rights of such
Person to receive such payment.

         Section 1611. Reliance on Judicial Order or Certificate of Liquidating
Agent.

                  Upon any payment or distribution of assets of the Company
referred to in this Article Sixteen, the Trustee, subject to the provisions of
Section 601, and the Holders of the Securities shall be entitled to rely upon
any order or decree entered by any court of competent jurisdiction in which such
insolvency, bankruptcy, receivership, liquidation, reorganization, dissolution,
winding up or similar case or proceeding is pending, or a certificate of the
trustee in bankruptcy, liquidating trustee, Custodian, receiver, assignee for
the benefit of creditors, agent or other Person making such payment or
distribution, delivered to the Trustee or to the Holders of

                                       86

Securities, for the purpose of ascertaining the Persons entitled to participate
in such payment or distribution, the holders of Senior Indebtedness and other
indebtedness of the Company, the amount thereof or payable thereon, the amount
or amounts paid or distributed thereon and all other facts pertinent thereto or
to this Article Sixteen.

         Section 1612. Trustee Not Fiduciary for Holders of Senior Indebtedness.

                  The Trustee shall not be deemed to owe any fiduciary duty to
the holders of Senior Indebtedness and shall not be liable to any such holders
if the Trustee shall in good faith mistakenly pay over or distribute to Holders
of Securities or to the Company or to any other Person cash, property or
securities to which any holders of Senior Indebtedness shall be entitled by
virtue of this Article or otherwise. With respect to the holders of Senior
Indebtedness, the Trustee undertakes to perform or to observe only such of its
covenants or obligations as are specifically set forth in this Article and no
implied covenants or obligations with respect to holders of Senior Indebtedness
shall be read into this Indenture against the Trustee.

                  Nothing in this Article shall apply to claims of or payments
to, the Trustee under or pursuant to Section 606.

evidenced by one or more instruments of substantially similar tenor signed by
such Holders or by holders of Preferred Securities in person or by an agent duly
appointed in writing. If, but only if, Securities of a series are issuable as
Bearer Securities, any request, demand, authorization, direction, notice,
consent, waiver or other action provided in or pursuant to this Indenture to be
given or taken by Holders of Securities of such series or by holders of
Preferred Securities may, alternatively, be embodied in and evidenced by the
record of Holders of Securities or by holders of Preferred Securities of such
series voting in favor thereof, either in person or by proxies duly appointed in
writing, at any meeting of Holders of Securities of such series duly called and
held in accordance with the provisions of Article Fourteen, or a combination of
such instruments and any such record. Except as herein otherwise expressly
provided, such action shall become effective when such instrument or instruments
or record or both are delivered to the Trustee and, where it is hereby expressly
required, to the Guarantor or the Company, as the case may be. Such instrument
or instruments and any such record and the action embodied therein and evidenced
thereby are herein sometimes referred to as the "Act" of the Holders or by
holders of Preferred Securities 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 (subject to
Section 315 of the Trust Indenture Act) conclusive in favor of the Trustee, the
Guarantor or the Company, and any agent of the Trustee or the Company or the
Guarantor, if made in the manner provided in this Section 104. The record of any
meeting of Holders of Securities shall be proved in the manner provided in
Section 1406.

         Without limiting the generality of this Section 104, unless otherwise
provided in or pursuant to this Indenture, a Holder, including a U.S. Depositary
that is a Holder of a global Security, may make, give or take, by a proxy, or
proxies, duly appointed in writing, any request,

                                       14
<PAGE>

demand, authorization, direction, notice, consent, waiver or other Act provided
in or pursuant to this Indenture to be made, given or taken by Holders, and a
U.S. Depositary that is a Holder of a global Security may provide its proxy or
proxies to the beneficial owners of interests in any such global Security
through such U.S. Depositary's standing instructions and customary practices.

         The Trustee may fix a record date for the purpose of determining the
Persons who are beneficial owners of interest in any permanent global Security
held by a U.S. Depositary entitled under the procedures of such U.S. Depositary
to make, give or take, by a proxy or proxies duly appointed in writing, any
request, demand, authorization, direction, notice, consent, waiver or other Act
provided in or pursuant to this Indenture to be made, given or taken by Holders.
If such a record date is fixed, the Holders on such record date or their duly
appointed proxy or proxies, and only such Persons, shall be entitled to make,
give or take such request, demand, authorization, direction, notice, consent,
waiver or other Act, whether or not such Holders remain Holders after such
record date. No such request, demand, authorization, direction, notice, consent,
waiver or other Act shall be valid or effective if made, given or taken more
than 90 days after such record date.

         (b) The fact and date of the execution by any Person of any such
instrument or writing may be proved in any reasonable manner which the Trustee
deems sufficient and in accordance with such reasonable rules as the Trustee may
determine; and the Trustee may in any instance require further proof with
respect to any of the matters referred to in this Section 104.

         (c) The ownership, principal amount and serial numbers of Registered
Securities held by any Person, and the date of the commencement and the date of
the termination of holding the same, shall be proved by the Security Register.

         (d) The ownership, principal amount and serial numbers of Bearer
Securities held by any Person, and the date of the commencement and the date of
the termination of holding the same, 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 reasonably acceptable to the Trustee,
the Guarantor and the Company, wherever situated, if such certificate shall be
deemed by the Company, the Guarantor and 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 Company,
the Guarantor and the Trustee to be satisfactory. The Trustee, the Company and
the Guarantor 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, principal amount and serial numbers of
Bearer Securities held by the Person so executing such instrument or writing and
the date of the commencement and the date of the termination of holding the same
may also be proved in any other manner which the Trustee, the Guarantor and the
Company deem sufficient.

         (e) If the Company or the Guarantor shall solicit from the Holders of
any Registered Securities any request, demand, authorization, direction, notice,
consent, waiver or

                                       15
<PAGE>

other Act, the Company may at its option (but is not obligated to), by Board
Resolution, fix in advance a record date for the determination of Holders of
Registered Securities entitled to give such request, demand, authorization,
direction, notice, consent, waiver or other Act. 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
Registered Securities of record at the close of business on such record date
shall be deemed to be Holders for the purpose 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 of Registered Securities shall be deemed effective
unless it shall become effective pursuant to the provisions of this Indenture
not later than six months after the record date.

         (f) Any request, demand, authorization, direction, notice, consent,
waiver or other Act by 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 or suffered to be done by the Trustee, any Security
Registrar, any Paying Agent, any Conversion Agent or the Company or the
Guarantor in reliance thereon, whether or not notation of such Act is made upon
such Security.

                   Section 105. Notices, etc. to Trustee, the Company and the
                                Guarantor.

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

         (a) the Trustee by any Holder or holder of a Preferred Security, the
Guarantor or 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: Institutional Trust Services, or

         (b) the Guarantor or the Company by the Trustee or any Holder or holder
of a Preferred Security, shall be sufficient for every purpose hereunder (unless
otherwise herein expressly provided) if in writing and mailed, first-class
postage prepaid, to the Guarantor or the Company, as applicable, addressed to
the attention of its Treasurer at the address of its principal office specified
in the first paragraph of this instrument or at any other address previously
furnished in writing to the Trustee, the Guarantor or the Company, as
applicable.

                   Section 106. Notice to Holders of Securities; Waiver.

         Except as otherwise expressly provided in or pursuant to this
Indenture, where this Indenture provides for notice to Holders of Securities of
any event,

         (a) such notice shall be sufficiently given to Holders of Registered
Securities if in writing and mailed, first-class postage prepaid, to each Holder
of a Registered Security 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; and

                                       16
<PAGE>

         (b) such notice shall be sufficiently given to Holders of Bearer
Securities, if any, if published in an Authorized Newspaper in The City of New
York and, if such Securities are then listed on any stock exchange outside the
United States, in an Authorized Newspaper in such city as the Company shall
advise the Trustee that such stock exchange so requires, on a Business Day at
least twice, the first such publication to be not earlier than the earliest date
and the second such publication not later than the latest 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 of a Registered Security 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 which is mailed in the manner herein
provided shall be conclusively presumed to have been duly given or provided. In
case by reason of the suspension of regular mail service or by reason of any
other cause it shall be impracticable to give such notice by mail, then such
notification as shall be made with the approval of the Trustee shall constitute
a sufficient notification for every purpose hereunder.

         In case 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 failure to give notice by
publication to Holders of Bearer Securities as provided above, nor any defect in
any notice so published, shall affect the sufficiency of any notice mailed to
Holders of Registered Securities as provided above.

         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 of Securities shall be filed with the
Trustee, but such filing shall not be a condition precedent to the validity of
any action taken in reliance upon such waiver.

                   Section 107. Language of Notices.

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

                   Section 108. Conflict with Trust Indenture Act.

         If any provision hereof limits, qualifies or conflicts with any duties
under any required provision of the Trust Indenture Act imposed hereon by
Section 318(c) thereof, such required provision shall control.

                   Section 109. 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.

         In case any provision in this Indenture, any Security, any Coupon or
any Guarantee 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 112. Benefits of Indenture.

         Except as otherwise expressly provided herein with respect to holders
of Senior Indebtedness and holders of Preferred Securities, nothing in this
Indenture, any Security or any Coupon, or in any Guarantee, express or implied,
shall give to any Person, other than the parties hereto, any Security Registrar,
any Paying Agent, any Conversion Agent and their successors hereunder and the
Holders of Securities or Coupons, any benefit or any legal or equitable right,
remedy or claim under this Indenture.

                   Section 113. Governing Law.

governed by and construed in accordance with the laws of the State of New York

thereof.

Securities, in any case where any Interest Payment Date, Business Day following
any Change in Control Purchase Date or Stated Maturity or Maturity of any
Security, or the last date on which a Holder has the right to convert or
exchange Securities of a series that are convertible or exchangeable, shall be a
Legal Holiday at any Place of Payment, then (notwithstanding any other provision
of this Indenture, any Security, Coupon or Guarantee other than a provision in
any Security, Coupon or Guarantee that specifically states that such provision
shall apply in lieu hereof) payment need not be made at such Place of Payment on
such date, and such Securities need not be converted or exchanged on such date
but such payment may be made, and such Securities may be converted or exchanged,
on the next succeeding day that is a Business Day at such Place of Payment with
the same force and effect as if made on the Interest Payment Date or at the
Stated Maturity or Maturity or on such last day for conversion or exchange, and

the period from and after such Interest Payment Date, Business Day following any
Change in Control Purchase Date, Stated Maturity, Maturity or last day for
conversion or exchange, as the case may be, to the next succeeding Business Day.

or recovery shall result in the actual receipt, by the payee, of the full amount
of the Required Currency expressed to be payable in respect of such payments,
(ii) shall be enforceable as an alternative or additional cause of action for
the purpose of recovering in the Required Currency the amount, if any, by which
such actual receipt shall fall short of the full amount of the Required Currency
so expressed to be payable and (iii) shall not be affected by judgment being
obtained for any other sum due under this Indenture. For purposes of the

         Guarantees to be endorsed on the Securities shall, subject to Section
201, be in substantially the form set forth below:

                                    GUARANTEE

         For value received, Apache Corporation, a corporation organized under
     the laws of the State of Delaware (the "Guarantor," which term includes any
     successor Person under the Indenture referred to in the Security upon which
     this Guarantee is endorsed), hereby irrevocably and unconditionally
     guarantees to the Holder of the Security upon which this Guarantee is
     endorsed and to the Trustee on behalf of the Trustee and such Holder the
     due and punctual payment of the principal of, and any premium, and Interest
     on, and any Additional Amounts with respect to, such Security, and any
     other amount due and payable pursuant to the terms of the Indenture or
     payments referred to therein, if any, when and as the same shall become due
     and payable, whether at the Stated Maturity, by declaration of
     acceleration, call for redemption, repurchase, or otherwise, according to
     the terms of such Security and of the Indenture referred to therein. In
     case of the failure of Apache Finance Australia Pty Ltd, a proprietary
     company with limited liability organized under the laws of the Australian
     Capital Territory, Australia (the "Company," which term includes any
     successor corporation under such Indenture), punctually to make any such
     payment of principal, any premium or Interest on or any Additional Amounts
     with respect to such Security, the Guarantor hereby agrees to cause any
     such payment to be made punctually when and as the same shall become due
     and payable, whether at the Stated Maturity or by declaration of
     acceleration, call for redemption or otherwise, and as if such payment were
     made by the Company.

         The Guarantor hereby agrees that its obligations hereunder shall be as
     if it were principal debtor and not merely surety, and shall be absolute
     and unconditional, irrespective of, and shall be unaffected by, any
     invalidity, irregularity or unenforceability

                                       20

     of such Security or such Indenture, any failure to enforce the provisions
     of such Security or such Indenture, or any waiver, modification or
     indulgence granted to the Company with respect thereto, by the holder of
     such Security or the Trustee or any other circumstance which may otherwise
     constitute a legal or equitable discharge of a surety or guarantor. The
     Guarantor hereby waives the benefits of division and discussion, diligence,
     presentment, demand of payment, filing of claims with a court in the event
     of merger, insolvency or bankruptcy of the Company, any right to require a
     proceeding first against the Company, protest or notice with respect to
     such Security or the indebtedness evidenced thereby and all demands
     whatsoever, and covenants that this Guarantee will not be discharged except
     by strict and complete performance of the obligations contained in such
     Security and this Guarantee. The Guarantor hereby agrees that, in the event
     of a default in payment of principal of, or any premium or Interest on, or
     any Additional Amounts with respect to, such Security, or default in any
     sinking fund or analogous payment referred to therein, legal proceedings
     may be instituted by the Trustee on behalf of, or by, the Holder of such
     Security, on the terms and conditions set forth in the Indenture, directly
     against the Guarantor to enforce this Guarantee without first proceeding
     against the Company.

         The Guarantor shall be subrogated to all rights of the Holder of such
     Security and the Trustee against the Company in respect of any amounts paid
     to such Holder by the Guarantor on account of such Security pursuant to the
     provisions of this Guarantee or the Indenture; provided, however, that the
     Guarantor shall not be entitled to enforce, or to receive any payments
     arising out of or based upon, such right of subrogation until the principal
     of, and any premium and Interest on, and any Additional Amounts required
     with respect to, all Securities issued under such Indenture shall have been
     paid in full.

         No reference herein to such Indenture and no provision of this
     Guarantee or of such Indenture shall alter or impair the guarantee of the
     Guarantor, which is absolute and unconditional, of the due and punctual
     payment of principal of, any premium and Interest on, and any Additional
     Amounts required with respect to, the Security upon which this Guarantee is
     endorsed.

         This Guarantee shall not be valid or obligatory for any purpose until
     the certificate of authentication of the Security upon which this Guarantee
     is endorsed shall have been manually executed by or on behalf of the
     Trustee under such Indenture.

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

         This Guarantee shall be deemed to be a contract made under the laws of
     the State of New York, and for all purposes shall be governed by and
     construed in accordance with the laws of the State of New York.

         This Guarantee is an unsecured obligation of the Guarantor, and is
     subordinated to all existing and future Guarantor Senior Indebtedness as
     set forth, and to the extent provided, in the Indenture. The Guarantor
     agrees, and each Holder by accepting a Security agrees, to the
     subordination of this Guarantee and authorizes the Trustee to give it
     effect and appoints the Trustee as attorney-in-fact for such purposes.

any instructions by the Company or the Guarantor with respect to a Security in
global form shall be in writing but need not be accompanied by or contained in
an Officers' Certificate and need not be accompanied by an Opinion of Counsel.

         Notwithstanding the provisions of Section 307, unless otherwise
specified in or pursuant to this Indenture or any Securities, payment of

(subject to Sections 315(a) through 315(d) of the Trust Indenture Act) shall be
fully protected in relying upon,

Indenture;

         (b) all conditions precedent to the authentication and delivery of such
Securities and Coupons, if any, appertaining thereto, have been complied with
and that such Securities and Coupons, when completed by appropriate insertions,
executed under the Company's corporate seal and attested by duly authorized
officers of the Company, delivered by duly authorized officers of the Company to
the Trustee for authentication pursuant to this Indenture, and authenticated and
delivered by the Trustee and issued by the Company in the manner and subject to
any conditions specified in such Opinion of Counsel, will constitute legally
valid and binding obligations of the Company, enforceable against the Company in
accordance with their terms, except as enforcement thereof may be subject to or
limited by bankruptcy, insolvency, reorganization, moratorium, arrangement,
fraudulent conveyance, fraudulent transfer or other similar laws relating to or
affecting creditors' rights generally, and subject to general principles of
equity (regardless of whether enforcement is sought in a proceeding in equity or
at law) and will entitle the Holders thereof to the benefits of this Indenture,
including the Guarantee; such Opinion of Counsel need express no opinion as to
the availability of equitable remedies;

         (c) Guarantees, when executed under the Guarantor's corporate seal and
attested by duly authorized officers of the Guarantor and endorsed upon a
Security that is authenticated and delivered by the Trustee and issued by the
Company in the manner and subject to any condition specified in such Opinion of
Counsel, will constitute legally valid and binding obligations of the Guarantor,
enforceable against the Guarantor in accordance with its terms, except as
enforcement thereof may be subject to or limited by bankruptcy, insolvency,
reorganization, moratorium, arrangement, fraudulent conveyance, fraudulent
transfer or other similar laws relating to or affecting creditors' rights
generally, and subject to general principles of equity (regardless of whether
enforcement is sought in a proceeding in equity or at law) and will entitle the
Holders to the benefits of this Indenture; such Opinion of Counsel need express
no opinion as to the availability of equitable remedies;

         (d) all laws and requirements in respect of the execution and delivery
by the Company of such Securities and Coupons, if any, have been complied with;
and

         (e) This Indenture has been qualified under the Trust Indenture Act;
and

     (2) Officers' Certificates of the Company and the Guarantor stating that,
in each case, to the best knowledge of the Persons executing such certificate,
no event which is, or after notice or lapse of time or both would become, an
Event of Default with respect to any of the Securities or the Guarantees shall
have occurred and be continuing.

         If all the Securities of any series are not to be issued at one time,
it shall not be necessary to deliver an Opinion of Counsel and Officers'
Certificates at the time of issuance of each Security, but such opinion and
certificate, with appropriate modifications, shall be delivered at or before the
time of issuance of the first Security of such series. After any such first
delivery, any separate request by the Company that the Trustee authenticate
Securities of such series for original issue will be deemed to be a
certification by the Company and the Guarantor that all conditions precedent
provided for in this Indenture relating to authentication and delivery of such
Securities continue to have been complied with.

         The Trustee shall not be required to authenticate or to cause an
Authenticating Agent to authenticate any Securities if the issue of such
Securities pursuant to this Indenture will affect the Trustee's own rights,
duties or immunities under the Securities and this Indenture or otherwise in a
manner which is not reasonably acceptable to the Trustee or if the Trustee,
being advised by counsel, determines that such action may not lawfully be taken.

         Each Registered Security shall be dated the date of its authentication.
Each Bearer Security and any Bearer Security in global form shall be dated as of
the date specified in or pursuant to this Indenture.

         No Security or Guarantee 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 a certificate of authentication
substantially in the form provided for in Section 202 or 611 executed by or on
behalf of the Trustee or by the Authenticating Agent by the manual signature of
one of its authorized officers. Such certificate upon any Security shall be
conclusive evidence, and the only evidence, that such Security has been duly
authenticated and delivered hereunder. Except as permitted by Section 306 or
307, the Trustee shall not authenticate and deliver any Bearer Security or
related Guarantee unless all Coupons appertaining thereto then matured have been
detached and canceled.

                       Section 304. Temporary Securities.

         Pending the preparation of definitive Securities, the Company may
execute and deliver to the Trustee and, upon Company Order and Guarantor Order,
the Trustee shall authenticate and deliver, in the manner provided in Section
303, temporary Securities in lieu thereof 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 or pursuant to this
Indenture, in bearer form with one or more Coupons or without Coupons and having
endorsed thereon Guarantees of the Guarantor substantially of the tenor of the
definitive Guarantees, and with such appropriate insertions, omissions,
substitutions and other variations as the officers executing such Securities or
Guarantees may determine, as conclusively evidenced by their execution of such
Securities or Guarantees, as the case may be. 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 the provisions thereof, if temporary Securities
are issued, the Company shall cause definitive Securities to be prepared without
unreasonable delay. After the preparation of definitive Securities of the same
series and containing terms and provisions that are identical to

                                       29
<PAGE>

those of any temporary Securities, such temporary Securities shall be
exchangeable for such definitive Securities with Guarantees of the Guarantor
endorsed thereon upon surrender of such temporary Securities at an Office or
Agency for such Securities, without charge to any Holder thereof. Upon surrender
for cancellation of any one or more temporary Securities (accompanied by any
unmatured 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 authorized denominations of the same series
and containing identical terms and provisions, each with a Guarantee of the
Guarantor endorsed thereon; provided, however, that no definitive Bearer
Security, except as provided in or pursuant to this Indenture, 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 or
pursuant to this Indenture. Unless otherwise provided in or pursuant to this
Indenture with respect to a temporary global Security, until so exchanged the
temporary Securities of any series shall in all respects be entitled to the same
benefits under this Indenture as definitive Securities of such series.

               Section 305. Registration, Transfer and Exchange.

         With respect to the Registered Securities of each series, if any, the
Company shall cause to be kept a register (each such register being herein
sometimes referred to as the "Security Register") at an Office or Agency for
such series in which, subject to such reasonable regulations as it may
prescribe, the Company shall provide for the registration of the Registered
Securities of such series and of transfers of the Registered Securities of such
series. Such Office or Agency shall be the "Security Registrar" for that series
of Securities. Unless otherwise specified in or pursuant to this Indenture or
the Securities, the Trustee shall be the initial Security Registrar for each
series of Securities. The Company shall have the right to remove and replace
from time to time the Security Registrar for any series of Securities; provided
that no such removal or replacement shall be effective until a successor
Security Registrar with respect to such series of Securities shall have been
appointed by the Company and shall have accepted such appointment by the
Company. In the event that the Trustee shall not be or shall cease to be
Security Registrar with respect to a series of Securities, it shall have the
right to examine the Security Register for such series at all reasonable times.
There shall be only one Security Register for each series of Securities.

         Upon surrender for registration of transfer of any Registered Security
of any series at any Office or Agency for such 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 denominated as authorized in or pursuant to this Indenture, of a
like aggregate principal amount bearing a number not contemporaneously
outstanding and containing identical terms and provisions, having Guarantees
duly endorsed thereon.

         At the option of the Holder, Registered Securities of any series may be
exchanged for other Registered Securities of the same series containing
identical terms and provisions, in any authorized denominations, and of a like
aggregate principal amount, upon surrender of the Securities to be exchanged at
any Office or Agency for such series. Whenever any Registered Securities are so
surrendered for exchange, the Company shall execute, and the Trustee shall

                                       30
<PAGE>

authenticate and deliver, the Registered Securities which the Holder making the
exchange is entitled to receive having Guarantees duly endorsed thereon.

         If provided in or pursuant to this Indenture, with respect to
Securities of any series, at the option of the Holder, Bearer Securities of such
series may be exchanged for Registered Securities of such series containing
identical terms, denominated as authorized in or pursuant to this Indenture and
in the same aggregate principal amount, upon surrender of the Bearer Securities
to be exchanged at any Office or Agency for such series, 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, such exchange may be effected if the
Bearer Securities are accompanied by payment in funds acceptable to the Company,
the Guarantor and the Trustee in an amount equal to the face amount of such
missing Coupon or Coupons, or the surrender of such missing Coupon or Coupons
may be waived by the Company, the Guarantor 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 Bearer
Security shall surrender to any Paying Agent any such missing Coupon in respect
of which such a payment shall have been made, such Holder shall be entitled to
receive the amount of such payment; provided, however, that, except as otherwise
provided in Section 1002, Interest represented by Coupons shall be payable only
upon presentation and surrender of those Coupons at an Office or Agency for such
series located outside the United States. Notwithstanding the foregoing, in case
a Bearer Security of any series is surrendered at any such Office or Agency for
such series in exchange for a Registered Security of such 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 date for payment of Defaulted
Interest, such Bearer Security shall be surrendered without the Coupon relating
to such Interest Payment Date or proposed date of payment, as the case may be
(or, if such Coupon is so surrendered with such Bearer Security, such Coupon
shall be returned to the Person so surrendering the Bearer Security), and
Interest or Defaulted Interest, as the case may be, shall 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 shall be payable only to the Holder of such Coupon when due in accordance
with the provisions of this Indenture.

         If provided in or pursuant to this Indenture with respect to Securities
of any series, at the option of the Holder, Registered Securities of such series
may be exchanged for Bearer Securities upon such terms and conditions as may be
provided in or pursuant to this Indenture with respect to such series.

         Whenever any Securities are surrendered for exchange as contemplated by
the immediately preceding two paragraphs, the Company shall execute, and the
Trustee shall authenticate and deliver, the Securities, having endorsed thereon
Guarantees of the Guarantor, which the Holder making the exchange is entitled to
receive.

         Notwithstanding the foregoing, except as otherwise provided in or
pursuant to this Indenture, any global Security shall be exchangeable for
definitive Securities only if (i) the Depositary is at any time unwilling,
unable or ineligible to continue as Depositary and a successor

                                       31
<PAGE>

depository is not appointed by the Company within 90 days of the date the
Company is so informed in writing, (ii) the Company executes and delivers to the
Trustee a Company Order to the effect that such global Security shall be so
exchangeable, or (iii) an Event of Default has occurred and is continuing with
respect to the Securities. If the beneficial owners of interests in a global
Security are entitled to exchange such interests for definitive Securities as
the result of an event described in clause (i), (ii) or (iii) of the preceding
sentence, then without unnecessary delay but in any event not later than the
earliest date on which such interests may be so exchanged, the Company shall
deliver to the Trustee definitive Securities in such form and denominations as
are required by or pursuant to this Indenture, and of the same series,
containing identical terms and in aggregate principal amount equal to the
principal amount of such global Security, executed by the Company. On or after
the earliest date on which such interests may be so exchanged, such global
Security shall be surrendered from time to time by the U.S. Depositary or such
other Depositary as shall be specified in the Company Order with respect
thereto, and in accordance with instructions given to the Trustee and the U.S.
Depositary or such other Depositary, as the case may be (which instructions
shall be in writing but need not be contained in or accompanied by an Officers'
Certificate or be accompanied by an Opinion of Counsel), as shall be specified
in the Company Order with respect thereto to the Trustee, as the Company's agent
for such purpose, to be exchanged, in whole or in part, for definitive
Securities as described above without charge. The Trustee shall authenticate and
make available for delivery, in exchange for each portion of such surrendered
global Security, a like aggregate principal amount of definitive Securities of
the same series of authorized denominations and of like tenor as the portion of
such global Security to be exchanged, which (unless such Securities are not
issuable both as Bearer Securities and as Registered Securities, in which case
the definitive Securities exchanged for the global Security shall be issuable
only in the form in which the Securities are issuable, as provided in or
pursuant to this Indenture) shall be in the form of Bearer Securities or
Registered Securities, or any combination thereof, as shall be specified by the
beneficial owner thereof, but subject to the satisfaction of any certification
or other requirements to the issuance of Bearer Securities; provided, however,
that no such exchanges may occur during a period beginning at the opening of
business 15 days before any selection of Securities of the same series to be
redeemed and ending on the relevant Redemption Date; and provided, further, that
(unless otherwise provided in or pursuant to this Indenture) no Bearer Security
delivered in exchange for a portion of a global Security shall be mailed or
otherwise delivered to any location in the United States. Promptly following any
such exchange in part, such global Security shall be returned by the Trustee to
such Depositary or the U.S. Depositary, as the case may be, or such other
Depositary or U.S. Depositary referred to above in accordance with the
instructions of the Company referred to above. If a Registered Security is
issued in exchange for any portion of a global Security after the close of
business at the Office or Agency for such Security where such exchange occurs on
or after (i) any Regular Record Date for such Security and before the opening of
business at such Office or Agency on the next Interest Payment Date, or (ii) any
Special Record Date for such Security and before the opening of business at such
Office or Agency on the related proposed date for payment of Interest or
Defaulted Interest, as the case may be, Interest shall 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 shall 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 global Security shall
be payable in accordance with the provisions of this Indenture.

                                       32
<PAGE>

         All Securities issued upon any registration of transfer or exchange of
Securities and all Guarantees endorsed thereon shall be the valid obligations of
the Company or the Guarantor, as the case may be, evidencing the same debt and
entitling the Holders thereof to the same benefits under this Indenture as the
Securities and Guarantees endorsed thereon surrendered upon such registration of
transfer or exchange.

         Every Registered Security presented or surrendered for registration of
transfer or for exchange or redemption shall (if so required by the Company or
the Security Registrar for such Security) be duly endorsed, or be accompanied by
a written instrument of transfer in form satisfactory to the Company and the
Security Registrar for such Security 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, or redemption of Securities, but the Company or the Trustee may
require payment of a sum sufficient to cover any tax or other governmental
charge.

         Except as otherwise provided in or pursuant to this Indenture, the
Company shall not be required (i) to issue, register the transfer of or exchange
any Securities during a period beginning at the opening of business 15 days
before the day of the selection for redemption of Securities of like tenor and
the same series under Section 1103 and ending at the close of business on the
day of such selection, 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 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, to the extent provided with respect to such Bearer Security, that such
Bearer Security may be exchanged for a Registered Security of like tenor and the
same series, provided that such Registered Security shall be immediately
surrendered for redemption with written instruction for payment consistent with
the provisions of this Indenture or (iv) to issue, register the transfer of or
exchange any Security which, in accordance with its terms, 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, subject to the provisions of
this Section 306, the Company shall execute and the Trustee shall authenticate
and deliver in exchange therefor a new Security of the same series containing
identical terms and of like principal amount, having endorsed thereon the
Guarantee of the Guarantor and bearing a number not contemporaneously
outstanding, with Coupons appertaining thereto corresponding to the Coupons, if
any, appertaining to the surrendered Security.

         If there be delivered to the Company, the Guarantor and to the Trustee
(i) evidence to their satisfaction of the destruction, loss or theft of any
Security or Coupon, and (ii) such security or indemnity as may be required by
them to save each of them and any agent of either of them harmless, then, in the
absence of notice to the Company, the Guarantor or the Trustee that such
Security or Coupon has been acquired by a protected purchaser, the Company shall
execute and, upon Company Request the Trustee shall authenticate and deliver, in
exchange for or in lieu

                                       33
<PAGE>

of any such mutilated, 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 containing identical terms and of like principal amount having endorsed
thereon the Guarantee of the Guarantor and bearing a number not
contemporaneously outstanding, with Coupons corresponding to the Coupons, if
any, appertaining to such destroyed, lost or stolen Security or to the Security
to which such destroyed, lost or stolen Coupon appertains.

         Notwithstanding the foregoing provisions of this Section 306, in case
any 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, pay such Security or Coupon; provided, however, that
principal of, any premium or Interest on or any Additional Amounts with respect
to any Bearer Securities shall, except as otherwise provided in Section 1002, be
payable only at an Office or Agency for such Securities located outside the
United States and, unless otherwise provided in or pursuant to this Indenture,
any Interest on Bearer Securities and any Additional Amounts with respect to
such Interest shall be payable only upon presentation and surrender of the
Coupons appertaining thereto.

         Upon the issuance of any new Security under this Section 306, the
Company or the Trustee 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, with any Coupons appertaining thereto, and the
Guarantee of the Guarantor endorsed thereon, issued pursuant to this Section 306
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 a
separate obligation of the Company and the Guarantor, respectively, whether or
not the destroyed, lost or stolen Security and Coupons appertaining thereto 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 such series and any Coupons
and related Guarantees duly issued hereunder.

         The provisions of this Section 306, as amended or supplemented pursuant
to this Indenture with respect to particular Securities or generally, shall be
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 and Certain Additional Amounts;
                            Rights to Interest and Certain Additional Amounts
                            Preserved.

         Unless otherwise provided in or pursuant to this Indenture, any
Interest on and any Additional Amounts with respect to any Registered Security
which shall be payable, and are punctually paid or duly provided for, on any
Interest Payment Date shall be paid to the Person in whose name such Security
(or one or more Predecessor Securities) is registered as of the close of
business on the Regular Record Date for such Interest. Unless otherwise provided
in or pursuant to this Indenture, in case a Bearer Security is surrendered in
exchange for a Registered Security

                                       34
<PAGE>

after the close of business at an Office or Agency for such Security on any
Regular Record Date therefor and before the opening of business at such Office
or Agency on the next succeeding Interest Payment Date therefor, such Bearer
Security shall be surrendered without the Coupon relating to such Interest
Payment Date and Interest shall not be payable on such Interest Payment Date in
respect of the Registered Security issued in exchange for such Bearer Security,
but shall be payable only to the Holder of such Coupon when due in accordance
with the provisions of this Indenture.

         Unless otherwise provided in or pursuant to this Indenture, any
Interest on and any Additional Amounts with respect to any Registered Security
which shall be payable, but shall not be punctually paid or duly provided for,
on any Interest Payment Date for such Registered Security (herein called
"Defaulted Interest") shall forthwith cease to be payable to the 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 or the Guarantor, at its
election in each case, as provided in Clause (1) or (2) below:

     (1) The Company or the Guarantor may elect to make payment of any Defaulted
Interest to the Person in whose name such Registered Security (or a Predecessor
Security thereof) shall be 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 or the Guarantor shall notify the Trustee in
writing of the amount of Defaulted Interest proposed to be paid on such
Registered Security and the date of the proposed payment, and at the same time
the Company or the Guarantor, as the case may be, shall deposit with the Trustee
an amount of money equal to the aggregate amount proposed to be paid in respect
of such Defaulted Interest or shall make arrangements satisfactory to the
Trustee for such deposit on or prior to the date of the proposed payment, such
money when so deposited to be held in trust for the benefit of the Person
entitled to such Defaulted Interest as in this Clause provided. Thereupon, the
Trustee shall fix a Special Record Date for the payment of such Defaulted
Interest which shall be not more than 15 days and not less than 10 days prior to
the date of the proposed payment and not less than 10 days after the receipt by
the Trustee of the notice of the proposed payment. The Trustee shall promptly
notify the Company of such Special Record Date and, in the name and at the
expense of the Company shall cause notice of the proposed payment of such
Defaulted Interest and the Special Record Date therefor to be mailed,
first-class postage prepaid, to the Holder of such Registered Security (or a
Predecessor Security thereof) 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 of
general circulation in the Borough of Manhattan, The City of New York, but such
publication 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 Person in whose name such Registered
Security (or a Predecessor Security thereof) shall be 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 is surrendered at the Office
or Agency for such Security in exchange for a Registered Security 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 Defaulted Interest and Defaulted Interest
shall not be payable on such

                                       35
<PAGE>

proposed date of payment in respect of the Registered Security issued in
exchange for such Bearer Security, but shall be payable only to the Holder of
such Coupon when due in accordance with the provisions of this Indenture.

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

         Unless otherwise provided in or pursuant to this Indenture or the
Securities of any particular series, at the option of the Company, Interest on
Registered Securities that bear Interest may be paid by mailing a check to the
address of the Person entitled thereto as such address shall appear in the
Security Register or by transfer to an account maintained by the payee with a
bank located in the United States.

         Subject to the foregoing provisions of this Section 307 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.

         If any convertible or exchangeable Security of any series is converted
or exchanged after any Regular Record Date and on or prior to the next
succeeding Interest Payment Date (other than any Security with respect to which
the Stated Maturity Date is prior to such Interest Payment Date), Interest that
is due on such Interest Payment Date shall be payable on such Interest Payment
Date notwithstanding such conversion or exchange, and such Interest (whether or
not punctually paid or duly provided for ) shall be paid to the Person in whose
name that Security is registered at the close of business on such Regular Record
Date. Except as otherwise expressly provided in the immediately preceding
sentence, in the case of any Security that is converted or exchanged, Interest
shall not be payable if the Regular Record Date is after the date of conversion
or exchange of such Security.

                      Section 308. Persons Deemed Owners.

         Prior to due presentment of a Registered Security for registration of
transfer, the Company, the Guarantor, the Trustee and any agent of the Company,
the Guarantor or the Trustee may treat the Person in whose name such Registered
Security is registered in the Security Register as the owner of such Registered
Security for the purpose of receiving payment of principal of, any premium and
(subject to Sections 305 and 307) Interest on and any Additional Amounts with
respect to such Registered Security and for all other purposes whatsoever,
whether or not any payment with respect to such Registered Security shall be
overdue, and neither the Company, the Guarantor nor the Trustee or any agent of
the Company, the Guarantor or the Trustee shall be affected by notice to the
contrary.

         The Company, the Guarantor, the Trustee and any agent of the Company,
the Guarantor or the Trustee may treat the bearer of any Bearer Security or the
bearer of any Coupon as the absolute owner of such Security or Coupon for the
purpose of receiving payment thereof or

                                       36
<PAGE>

on account thereof and for all other purposes whatsoever, whether or not any
payment with respect to such Security or Coupon shall be overdue, and neither
the Company, the Guarantor, the Trustee nor any agent of the Company, the
Guarantor or the Trustee shall be affected by notice to the contrary.

         No holder of any beneficial interest in any global Security held on its
behalf by a Depositary shall have any rights under this Indenture with respect
to such global Security, and such Depositary may be treated by the Company, the
Guarantor, the Trustee, and any agent of the Company, the Guarantor or the
Trustee as the owner of such global Security for all purposes whatsoever. None
of the Company, the Guarantor, the Trustee, any Paying Agent, Conversion Agent
or the Security Registrar will have any responsibility or liability for any
aspect of the records relating to or payments made on account of beneficial
ownership interests of a global Security or for maintaining, supervising or
reviewing any records relating to such beneficial ownership interests.

                           Section 309. Cancellation.

         All Securities and Coupons surrendered for payment, redemption,
registration of transfer, exchange or conversion or for credit against any
sinking fund payment shall, if surrendered to any Person other than the Trustee,
be delivered to the Trustee, and any such Securities and Coupons, as well as
Securities and Coupons surrendered directly to the Trustee for any such purpose,
shall be canceled promptly by the Trustee. The Company or the Guarantor may at
any time deliver to the Trustee for cancellation any Securities or Coupons
previously authenticated and delivered hereunder which the Company or the
Guarantor may have acquired in any manner whatsoever, and all Securities or
Coupons so delivered shall be canceled promptly by the Trustee. No Securities or
Coupons shall be authenticated in lieu of or in exchange for any Securities
canceled as provided in this Section 309, except as expressly permitted by or
pursuant to this Indenture. All canceled Securities and Coupons held by the
Trustee shall be destroyed by the Trustee in accordance with its customary
procedures, unless by a Company Order or Guarantor Order, the Company or the
Guarantor directs their return to it.

                           Section 310. Computation of Interest.

         Except as otherwise provided in or pursuant to this Indenture or in any
Security, Interest on the Securities shall be computed on the basis of a 360-day
year of twelve 30-day months.

                                  ARTICLE FOUR

                     SATISFACTION AND DISCHARGE OF INDENTURE

                           Section 401. Satisfaction and Discharge.

         Upon the direction of the Company by a Company Order or the Guarantor
by a Guarantor Order, this Indenture shall cease to be of further effect with
respect to any series of Securities specified in such Company Order or Guarantor
Order and any Coupons appertaining thereto, and the Trustee, on receipt of a
Company Order or Guarantor Order, at the expense of the

                                       37
<PAGE>

Company and the Guarantor, shall execute proper instruments acknowledging
satisfaction and discharge of this Indenture as to such series, when

    (1)  either

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

or

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

             (i)   have become due and payable, or

             (ii)  will become due and payable at their Stated Maturity within

         In the event there are Securities of two or more series hereunder, the
Trustee shall be required to execute an instrument acknowledging satisfaction
and discharge of this Indenture only if requested to do so with respect to
Securities of such series as to which it is Trustee and if the other conditions
thereto are met.

         Notwithstanding the satisfaction and discharge of this Indenture with
respect to any series of Securities, the obligations of the Company and the
Guarantor to the Trustee under Section 606 and, if money shall have been
deposited with the Trustee pursuant to subclause (b) of clause (1) of this
Section 401, the obligations of the Trustee, the Guarantor and the Company with
respect to the Securities of such series under Sections 305, 306, 403, 1002,
1003 and Article Twelve, with respect to the payment of Additional Amounts, if
any, with respect to such Securities as contemplated by Section 1004 (but only
to the extent that the Additional Amounts payable with respect to such
Securities exceed the amount deposited in respect of such Additional Amounts
pursuant to subclause (b) of clause (1) of this Section 401, and, unless
otherwise provided pursuant to Section 301 with respect to the Securities of
such series, any rights to convert or exchange the Securities of such series
into other securities in accordance with their terms), shall survive.

                Section 402. Defeasance and Covenant Defeasance.

         (1) Unless, pursuant to Section 301, either or both of (i) defeasance
of the Securities of or within a series under clause (2) of this Section 402, or
(ii) covenant defeasance of the Securities of or within a series under clause
(3) of this Section 402 shall not be applicable with respect to the Securities
of such series, then such provisions, together with the other provisions of this
Section 402 (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 or Officers' Certificate, at any time, with respect
to such Securities and any Coupons appertaining thereto, elect to have Section
402(2) or Section 402(3) be applied to such Outstanding Securities and any
Coupons appertaining thereto upon compliance with the conditions set forth below
in this Section 402.

         (2) Upon the Company's exercise of the above option applicable to this
Section 402(2) with respect to any Securities of or within a series, the Company
and the Guarantor shall be deemed to have been discharged from their respective
obligations with respect to such Outstanding Securities and any Coupons
appertaining thereto, and with respect to the Guarantees endorsed thereon, on
the date the conditions set forth in clause (4) of this Section 402 are
satisfied (hereinafter, "defeasance"). For this purpose, such defeasance means
that the Company and the Guarantor shall be deemed to have paid and discharged
the entire Indebtedness represented by such Outstanding Securities and any
Coupons appertaining thereto, and such corresponding Guarantees, which shall
thereafter be deemed to be "Outstanding" only for the purposes of clause (5) of
this Section 402 and the other Sections of this Indenture referred to in clauses
(i) and (ii) 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: (i) the rights of Holders of such
Outstanding Securities and any Guarantees and Coupons appertaining thereto to
receive, solely from the trust fund described in clause (4) of this Section 402
and as more fully set forth in such Section, payments of the

                                       39
<PAGE>

principal of, any premium and Interest or any Additional Amounts with respect
to, such Securities and any Coupons appertaining thereto when such payments are
due, and any rights of Holder to convert or exchange such Securities into or for
Common Stock or other securities, cash or property, (ii) the obligations of the
Company and the Trustee with respect to such Securities under Sections 305, 306,
1002 and 1003, with respect to the payment of Additional Amounts, if any, on
such Securities as contemplated by Section 1004 (but only to the extent that the
Additional Amounts payable with respect to such Securities exceed the amount
deposited in respect of such Additional Amounts pursuant to Section 402(4)(a)
below), and any obligations of the Guarantor relating to a surviving obligation
of the Company, (iii) the rights, powers, trusts, duties and immunities of the
Trustee hereunder and (iv) this Section 402. The Company may exercise its option
under this Section 402(2) notwithstanding the prior exercise of its option under
clause (3) of this Section 402 with respect to such Securities and any Coupons
appertaining thereto.

         (3) Upon the Company's exercise of the above option applicable to this
Section 402(3) with respect to any Securities of or within a series, the Company
and the Guarantor, to the extent specified pursuant to Section 301, shall be
released from their respective obligations in respect of any covenant applicable
to such Securities or the Guarantees endorsed thereon, with respect to such
Outstanding Securities and any Coupons appertaining thereto on and after the
date the conditions set forth in clause (4) of this Section 402 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 any such 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 and the Guarantees endorsed
thereon, the Company and the Guarantor 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(3) or 501(4) or
otherwise, as the case may be, but, except as specified above, the remainder of
this Indenture and such Securities and Coupons appertaining thereto and the
Guarantees endorsed thereon shall be unaffected thereby.

         (4) The following shall be the conditions to application of clause (2)
or (3) of this Section 402 to any Outstanding Securities of or within a series
and any Coupons appertaining thereto and the Guarantees endorsed thereon:

         (a) The Company or the Guarantor 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 Section 402 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,

                                       40
<PAGE>

               (1) an amount in Dollars or in such Foreign Currency 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
         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, any premium or Interest on or any
         Additional Amounts with respect to such Securities and any Coupons
         appertaining thereto, money in an amount, or

               (3) a combination thereof,

in any case, in an amount, sufficient, without consideration of any reinvestment
of such principal and Interest, in the opinion of a nationally recognized firm
of independent public accountants expressed in a written certification thereof
delivered to the Trustee, to pay and discharge, and which shall be applied by
the Trustee (or other qualifying trustee) to pay and discharge, the principal
of, any premium or Interest on or any Additional Amounts with respect to such
Outstanding Securities and any Coupons appertaining thereto on the Stated
Maturity of such principal or installment of principal or Interest on the day on
which such payments are due and payable in accordance with the terms of this
Indenture and of such Securities and any Coupons appertaining thereto.

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

         (c) No Event of Default or event which with notice or lapse of time or
both would become an Event of Default with respect to such Securities and any
Coupons appertaining thereto shall have occurred and be continuing on the date
of such deposit and, with respect to defeasance only, 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 clause (2) of this Section 402,
the Company or the Guarantor shall have delivered to the Trustee an Opinion of
Counsel stating that (i) the Company or the Guarantor has received from the
Internal Revenue Service a letter ruling, or there has been published by the
Internal Revenue Service a Revenue 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.

                                       41
<PAGE>

         (e) In the case of an election under clause (3) of this Section 402,
the Company and the Guarantor shall have delivered to the Trustee an Opinion of
Counsel to the effect that the Holders of such Outstanding Securities and any
Coupons appertaining thereto will not recognize income, gain or loss for Federal
income tax purposes as a result of such covenant defeasance and will be subject
to Federal income tax on the same amounts, in the same manner and at the same
times as would have been the case if such covenant defeasance had not occurred.

         (f) The Company and the Guarantor shall have delivered to the Trustee
an Officers' Certificate and an Opinion of Counsel, each stating that all
conditions precedent to the defeasance or covenant defeasance under clause (2)
or (3) of this Section 402 (as the case may be) have been complied with.

         (g) Notwithstanding any other provisions of this Section 402(4), 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 or the Guarantor in connection therewith pursuant to Section 301.

         (5) 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
402(5) and Section 403, the "Trustee") pursuant to clause (4) of Section 402 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 of,
any premium or Interest on or any Additional Amounts but such money need not be
segregated from other funds except to the extent required by law.

         Unless otherwise specified in or pursuant to this Indenture or any
Security, if, after a deposit referred to in Section 402(4)(a) has been made,
(a) the Holder of a Security in respect of which such deposit was made is
entitled to, and does, elect pursuant to Section 301 or the terms of such
Security to receive payment in a Currency other than that in which the deposit
pursuant to Section 402(4)(a) has been made in respect of such Security, or (b)
a Conversion Event occurs in respect of the Foreign Currency in which the
deposit pursuant to Section 402(4)(a) has been made, the indebtedness
represented by such Security and any Coupons appertaining thereto and the
Guarantees endorsed thereon shall be deemed to have been, and will be, fully
discharged and satisfied through the payment of the principal of, any premium or
Interest on or any Additional Amounts with respect to, such Security as the same
becomes due out of the proceeds yielded by converting (from time to time as
specified below in the case of any such election) the amount or other property
deposited in respect of such Security into the Currency in which such Security
becomes payable as a result of such election or Conversion Event based on (x) in
the case of payments made pursuant to clause (a) above, the applicable market
exchange rate for such Currency in effect on the second Business Day prior to
each payment date, or (y) with respect to a Conversion Event, the applicable
market exchange rate for such Foreign Currency in effect (as nearly as feasible)
at the time of the Conversion Event. Unless otherwise provided pursuant to

                                       42
<PAGE>

Section 301, the right, if any, to extend an Interest payment period shall
terminate upon defeasance or covenant defeasance, as the case may be.

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

         Anything in this Section 402 to the contrary notwithstanding, the
Trustee shall deliver or pay to the Company from time to time upon Company
Request, or the Guarantor, as the case may be, upon Guarantor's Request, any
money or Government Obligations (or other property and any proceeds therefrom)
held by it as provided in clause (4) of this Section 402 which, in the opinion
of a nationally recognized firm of independent public accountants expressed in a
written certification thereof delivered to the Trustee, are in excess of the
amount thereof which would then be required to be deposited to effect a
defeasance or covenant defeasance, as applicable, in accordance with this
Section 402.

                          Section 403. Application of Trust Money.

         Subject to the provisions of the last paragraph of Section 1003, all
money and Government Obligations deposited with the Trustee pursuant to Section
401 or 402 shall be held in trust and applied by it, in accordance with the
provisions of the Securities, the Coupons and this Indenture, to the payment,
either directly or through any Paying Agent (including the Company or the
Guarantor acting as its own Paying Agent) as the Trustee may determine, to the
Persons entitled thereto, of the principal, premium, Interest and Additional
Amounts for whose payment such money has or Government Obligations have been
deposited with or received by the Trustee; but such money and Government
Obligations need not be segregated from other funds except to the extent
required by law.

                          Section 404. Reinstatement.

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

        Section 502. Acceleration of Maturity; Rescission and Annulment.

         If an Event of Default with respect to Securities of any series at the
time Outstanding (other than an Event of Default specified in clause (6) or (7)
of Section 501) occurs and is continuing, then the Trustee or the Holders of not
less than 25% in principal amount of the Outstanding Securities of such series
may declare the principal of all the Securities of such series, or such lesser
amount as may be provided for in the Securities of such series, to be due and
payable immediately, by a notice in writing to the Company and the Guarantor
(and to the Trustee if given by the Holders), and upon any such declaration such
principal or such lesser amount shall become immediately due and payable;
provided that in the case of a series of Securities then held by a Trust, if
upon an Event of Default with respect to the Securities of that series the
Trustee has, or the Holders of not less than 25% in principal amount of the
Outstanding Securities of such series have, failed to declare the principal of
all the Securities of such series to be due and payable immediately, the holders
of not less than 25% in aggregate liquidation amount of the outstanding

to the Company and to the Trustee.

                                       45
<PAGE>

         If an Event of Default specified in clause (6) or (7) of Section 501
occurs, all unpaid principal of and accrued Interest on the Outstanding
Securities of that series (or such lesser amount as may be provided for in the
Securities of such series) shall ipso facto become and be immediately due and
payable without any declaration or other act on the part of the Trustee or any
Holder of any Security of that series.

         At any time after Securities of any series have been accelerated 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 not less
than a majority in principal amount of the Outstanding Securities of such series
(subject to, in the case of any series of Securities held as assets of a Trust
and with respect to which a Security Exchange has not theretofore occurred, such
consent of the holders of the Preferred Securities and the common securities of
such Trust as may be required under the Trust Agreement of such Trust), by
written notice to the Trustee, the Guarantor and the Company, may rescind and
annul such declaration and its consequences if:

         (1) the Company or the Guarantor has paid or deposited with the Trustee
a sum of money sufficient to pay:

         (a) all overdue installments of any Interest on and Additional Amounts
     with respect to all Securities of such series and any Coupon appertaining
     thereto;

         (b) the principal of and any premium on any Securities of such series
     which have become due otherwise than by such declaration of acceleration
     and Interest thereon and any Additional Amounts with respect thereto at the
     rate or rates borne by or provided for in such Securities;

         (c) to the extent that payment of such Interest or Additional Amounts
     is lawful, Interest upon overdue installments of any Interest and
     Additional Amounts at the rate or rates borne by or provided for in such
     Securities;

         (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 all other amounts due the Trustee under
     Section 606; and

         (2) all Events of Default with respect to Securities of such series,
other than the non-payment of the principal of, any premium and Interest on, and
any Additional Amounts with respect to Securities of such series which shall
have become due solely by such declaration of acceleration, shall 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:

                                       46
<PAGE>

         (1) there is a failure to pay any installment of Interest on or any
Additional Amounts with respect to any Security or any Coupon appertaining
thereto when such Interest or Additional Amounts shall have become due and
payable and such default continues for a period of 30 days; or

         (2) there is a failure to pay the principal of or any premium on any
Security at its Maturity;

the Company shall, upon demand of the Trustee, pay to the Trustee, for the
benefit of the Holders of such Securities and any Coupons appertaining thereto,
the whole amount of money then due and payable with respect to such Securities
and any Coupons appertaining thereto, with Interest upon the overdue principal,
any premium and, to the extent that payment of such Interest shall be legally
enforceable, upon any overdue installments of Interest and Additional Amounts at
the rate or rates borne by or provided for in such Securities, and, in addition
thereto, such further amount of money 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 and all other
amounts due to the Trustee under Section 606.

         If the Company or the Guarantor fails to pay the money it is required
to pay the Trustee pursuant to the preceding paragraph forthwith upon the demand
of the Trustee, the Trustee, in its own name and as trustee of an express trust,
may institute a judicial proceeding for the collection of the money so due and
unpaid, and may prosecute such proceeding to judgment or final decree, and may
enforce the same against the Company or the Guarantor or any other obligor upon
such Securities and any Coupons appertaining thereto or the Guarantees endorsed
thereon and collect the monies adjudged or decreed to be payable in the manner
provided by law out of the property of the Company, the Guarantor or any other
obligor upon such Securities and any Coupons appertaining thereto or the
Guarantees endorsed thereon, 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 Coupons appertaining thereto 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 such Securities or in aid of the exercise of any power granted
herein or therein, 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, the Guarantor or any other obligor
upon the Securities or the Guarantees endorsed thereon or the property of the
Company, the Guarantor or such other obligor or their creditors, the Trustee
(irrespective of whether the principal of the Securities shall then be due and
payable as therein expressed or by declaration or otherwise and irrespective of
whether the Trustee shall have made any demand on the Company or the Guarantor
for the payment of any overdue principal, premium, Interest or Additional
Amounts) shall be entitled and empowered, by intervention in such proceeding or
otherwise,

                                       47
<PAGE>

         (1) 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 the principal
and any premium, Interest and Additional Amounts owing and unpaid in respect of
the Securities and any Coupons appertaining thereto 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 or counsel) and of the
Holders of Securities or any Coupons allowed in such judicial proceeding, and

         (2) to collect and receive any monies 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 or any 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 of Securities or any Coupons, to pay to the Trustee any
amount due to it for the reasonable compensation, expenses, disbursements and
advances of the Trustee, its agents and counsel and any other amounts due the
Trustee under Section 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 any 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 any Coupon, in any such proceeding; provided, however, that the
Trustee may, on behalf of the Holders, vote for the election of a trustee in
bankruptcy or similar official and be a member of a creditors' committee or
other similar committee.

                   Section 505. Trustee May Enforce Claims without Possession of
                                Securities, Guarantees or Coupons.

         All rights of action and claims under this Indenture or any of the
Securities, the Guarantees or any Coupons may be prosecuted and enforced by the
Trustee without the possession of any of the Securities, Guarantees 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 or judgment, after provision for the
payment of the reasonable compensation, expenses, disbursements and advances of
the Trustee, its agents and counsel, shall be for the ratable benefit of each
and every Holder of a Security or Coupon 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 any
premium, Interest or 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;

<PAGE>

         SECOND: To the payment of the amounts then due and unpaid upon the
     Securities and any Coupons for principal and any premium, Interest and
     Additional Amounts 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 any premium, Interest and Additional Amounts,
     respectively;

         THIRD: The balance, if any, to the Person or Persons entitled thereto.

                       Section 507. Limitations on Suits.

         Except as provided in Sections 508 or 516, no Holder of any Security of
any series or any Coupons appertaining thereto, or holder of Preferred
Securities of the Trust, if any, that is the Holder of Securities of that
series, shall have any right to institute any proceeding, judicial or otherwise,
with respect to this Indenture, the Guarantees, the Securities of any series or
any Coupons appertaining thereto, or for the appointment of a receiver or
trustee, or for any other remedy hereunder, unless:

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

         (2) the Holders of not less than 25% in principal amount of the
Outstanding Securities of such series or the holders of not less than 25% in
aggregate amount of such outstanding Preferred Securities 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 of such Outstanding Securities of such
securities or the holder or holders of such outstanding Preferred Securities
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

         (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 such series or the holders of
a majority in aggregate liquidation amount of such outstanding Preferred
Securities;

it being understood and intended that no one or more of such Holders of such
Outstanding Securities of such series or the holder or holders of such
outstanding Preferred Securities shall have any right in any manner whatever by
virtue of, or by availing of, any provision of this Indenture or any Security or
Guarantee to affect, disturb or prejudice the rights of any other such Holders
or Holders of Securities of any other series or holder or holders of Preferred
Securities of another Trust, or to obtain or to seek to obtain priority or
preference over any other Holders of such Outstanding Securities of such series
or the holder or holders of such outstanding Preferred Securities 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 and any Premium, 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, any premium and (subject
to Sections 305 and 307) Interest on, and any Additional Amounts with respect to
such Security or payment of such Coupon or payment pursuant to the Guarantee
endorsed on such Security, as the case may be, on the respective Stated Maturity
or Maturities therefor specified in such Security or Coupon (or, in the case of
redemption, on the Redemption Date or, in the case of repayment at the option of
such Holder if provided in or pursuant to this Indenture, on the date such
repayment is due, or in the case of a Change in Control, or as to any Change in
Control Purchase Notice given timely, on the Change in Control Purchase Date)
and to convert or exchange such Security in accordance with its terms, if
applicable, and to institute suit for the enforcement of any such payment or
conversion or exchange, and such right 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 a 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 Guarantor, the Trustee and each such Holder 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 each such Holder 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 each and every Holder of a Security or a Coupon is intended
to be exclusive of any other right or remedy, and every right and remedy, to the
extent permitted by law, shall 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, to the extent permitted by law, prevent the
concurrent assertion or employment of any other appropriate right or remedy.

                   Section 511. Delay or Omission not Waiver.

         No delay or omission of the Trustee or of any Holder of any Security or
Coupon to exercise any right or remedy accruing upon any Event of Default shall
impair any such right or remedy or constitute a waiver of any such Event of
Default or an acquiescence therein. Every right and remedy given by this Article
or by law to the Trustee or to any Holder of a Security or a Coupon may be
exercised from time to time, and as often as may be deemed expedient, by the
Trustee or by such Holder, as the case may be.

                   Section 512. Control by Holders of Securities.

         Subject to Section 601(e), the Holders of a majority in principal
amount of the Outstanding Securities of any series or, if that series of
Securities is held by a Trust, the holders of a majority in aggregate
liquidation amount of the Preferred Securities of that Trust, shall have the
right to direct the time, method and place of conducting any proceeding for any
remedy available to the Trustee or exercising any trust or power conferred on
the Trustee with respect to the Securities of such series and any Coupons
appertaining thereto, provided that:

         (1) such direction shall not be in conflict with any rule of law or
with this Indenture or with the Securities of any series;

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

         (3) such direction is not unduly prejudicial to the rights of the other
Holders of Securities of such series not joining in such action.

                   Section 513. Waiver of Past Defaults.

         Subject to Section 502, the Holders of not less than a majority in
principal amount of the Outstanding Securities of any series, or, if that series
of Securities is held by a Trust, the holders of a majority in aggregate
liquidation amount of the Preferred Securities of that Trust, on behalf of the
Holders of all the Securities of such series and any Coupons appertaining
thereto may waive any past or prospective default hereunder with respect to such
series and its consequences, except a default:

         (1) in the payment of the principal of, any premium or Interest on, or
any Additional Amounts with respect to, any Security of such series or any
Coupons appertaining thereto; or

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

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

                   Section 514. Waiver of Stay or Extension Laws.

         Each of the Company and the Guarantor covenants that (to the extent
that it may lawfully do so) it will not at any time insist upon, or plead, or in
any manner whatsoever claim or take the benefit or advantage of, any stay or
extension law wherever enacted, now or at any time hereafter in force, which may
affect the covenants or the performance of this Indenture; and each of the
Company and the Guarantor expressly waives (to the extent that it may lawfully
do so) all benefit or advantage of any such law and covenants that it will not
hinder, delay or impede the

                                       51
<PAGE>

execution of any power herein granted to the Trustee, but will suffer and permit
the execution of every such power as though no such law had been enacted.

                      Section 515. Undertaking for Costs.

         All parties to this Indenture agree, and each Holder of any Security by
his acceptance thereof shall be deemed to have agreed, that any court may in its
discretion require, in any suit for the enforcement of any right or remedy under
this Indenture, or in any suit against the Trustee for any action taken or
omitted by it as Trustee, the filing by any party litigant in such suit of an
undertaking to pay the costs of such suit, and that such court may in its
discretion assess reasonable costs, including reasonable attorneys' fees,
against any party litigant in such suit having due regard to the merits and good
faith of the claims or defenses made by such party litigant; but the provisions
of this Section 515 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 Outstanding Securities of any series, or,
if a series of Securities is held by a Trust, the holders of more than 10%
aggregate liquidation amount of the Preferred Securities of that Trust, or to
any suit instituted by any Holder or holder of Preferred Securities, if any, for
the enforcement of the payment of the principal of, any premium or Interest on
or Additional Amounts with respect to any Security on or after the respective
Stated Maturities expressed in such Security or pursuant to Section 516 (or, in
the case of redemption, on or after the Redemption Date, in the case of
repayment, on or after the date for repayment and, in the case of Change of
Control, on or after the date for payment of the Change of Control Purchase
Price) or for the enforcement of the right, if any, to convert or exchange any
Security into Common Stock or other securities, cash or property in accordance
with its terms.

                      Section 516. Direct Action Right of Holders of Trust
                                   Preferred Securities.

         If an Event of Default has occurred and is continuing and is
attributable either to (a) the failure of the Company or the Guarantor to pay
the principal of or any premium or Interest on or Additional Amounts with
respect to the Securities on the due date therefor or (b) the failure by the
Company or the Guarantor to deliver the required securities or other property
upon an appropriate conversion or exchange right election, and an event of
default has occurred and is continuing under the applicable Trust Agreement, a
holder of the related Preferred Securities, in lieu of any action that may
otherwise be taken hereunder as a Holder of Securities, may institute a legal
proceeding directly against the Company and/or the Guarantor for enforcement of
payment to such holder of the principal of or any premium or Interest on or
Additional Amounts with respect to such Securities having a principal amount
equal to the liquidation amount of the Preferred Securities held by such holder
or for enforcement of such conversion or exchange rights, as the case may be (a
"Direct Action"). Notwithstanding anything contained herein to the contrary,
neither the Company nor the Guarantor may amend this Indenture to remove the
foregoing right to bring a Direct Action without the prior written consent of
the holders of all of the Preferred Securities outstanding affected thereby.
Notwithstanding any payments made to a holder of Preferred Securities by the
Company or the Guarantor in connection with a Direct Action, the Company and the
Guarantor shall remain obligated to pay the principal of, any premium or
Interest on or Additional Amounts with respect to the related Securities, and
the Company shall be subrogated to the rights of the holder of such Preferred
Securities with respect to payments on the

                                       52
<PAGE>

Preferred Securities to the extent of any payments made by the Company or the
Guarantor as the case may be to such holder in any Direct Action.

                                   THE TRUSTEE

                     Section 601. Certain Rights of Trustee.

         Subject to Sections 315(a) through 315(d) of the Trust Indenture Act:

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

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

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

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

         (e) the Trustee shall be under no obligation to exercise any of the
     rights or powers vested in it by or pursuant to this Indenture at the
     request or direction of any of the Holders of Securities of any series or
     any Coupons appertaining thereto 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;

         (f) the Trustee shall not be bound to make any investigation into the
     facts or matters stated in any resolution, certificate, statement,
     instrument, opinion, report, notice, request, direction, consent, order,
     bond, security, coupon or other paper or document, but the Trustee, in its
     discretion, may make such further inquiry

                                       53
<PAGE>

     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, during business hours and upon reasonable
     notice, the books, records and premises of the Company and the Guarantor,
     personally or by agent or attorney;

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

         (h) the Trustee shall not be charged with knowledge of any default (as
     defined in Section 602) or Event of Default with respect to the Securities
     of any series for which it is acting as Trustee unless either (1) a
     Responsible Officer of the Trustee assigned to the Corporate Trust
     Department of the Trustee (or any successor division or department of the
     Trustee) shall have actual knowledge of such default or Event of Default or
     (2) written notice of such default or Event of Default shall have been
     given to the Trustee by the Company, the Guarantor or any other obligor on
     such Securities or by any Holder of such Securities; and

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

                        Section 602. 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 by mail to
all Holders of Securities of such series entitled to receive reports pursuant to
Section 703(3), 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, any premium or
Interest on or Additional Amounts with respect to, any Security of such series,
the Trustee shall be protected in withholding such notice if and so long as a
committee of Responsible Officers of the Trustee in good faith determines that
the withholding of such notice is in the best interest of the Holders of
Securities and Coupons of such series. For the purpose of this Section 602, the
term "default" means any event which is, or after notice or lapse of time or
both would become, an Event of Default with respect to Securities of such
series.

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

         The recitals contained herein and in the Securities, except the
Trustee's certificate of authentication, and in any Coupons shall be taken as
the statements of the Company and the Guarantor, and neither the Trustee nor any
Authenticating Agent assumes any responsibility for their correctness. The
Trustee makes no representations as to the validity or sufficiency of this
Indenture or of the Securities or the Coupons appertaining thereto or the
Guarantees, except that the Trustee represents that it is duly authorized to
execute and deliver this Indenture, authenticate the Securities and perform its
obligations hereunder and that the statements made by it in a Statement of
Eligibility and Qualification on Form T-1 supplied to the Company are true and
accurate, subject to the qualifications set forth therein. Neither the Trustee
nor any Authenticating

                                       54
<PAGE>

Agent shall be accountable for the use or application by the Company of the
Securities or the proceeds thereof.

                        Section 604. May Hold Securities.

         The Trustee, any Authenticating Agent, any Paying Agent, any Conversion
Agent, any Security Registrar or any other Person that may be an agent of the
Trustee, the Company or the Guarantor, in its individual or any other capacity,
may become the owner or pledgee of Securities or Coupons and, subject to
Sections 310(b) and 311 of the Trust Indenture Act, may otherwise deal with the
Company and the Guarantor with the same rights it would have if it were not
Trustee, Authenticating Agent, Paying Agent, any Conversion Agent, Security
Registrar or such other Person.

                        Section 605. Money Held in Trust.

         Except as provided in Section 403 and Section 1003, money held by the
Trustee in trust hereunder need not be segregated from other funds except to the
extent required by law and shall be held uninvested. The Trustee shall be under
no liability for Interest on any money received by it hereunder except as
otherwise agreed in writing with the Company or the Guarantor, as the case may
be.

                        Section 606. Compensation and Reimbursement.

         Each of the Company and the Guarantor, jointly and severally, agrees:

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

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

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

         As security for the performance of the obligations of the Company under
this Section 606, the Trustee shall have a lien prior to the Securities of any
series upon all property and funds held or collected by the Trustee as such,
except funds held in trust for the payment of principal of, and premium or
Interest on or any Additional Amounts with respect to particular Securities or
any Coupons appertaining thereto.

<PAGE>

         Any compensation or expense incurred by the Trustee after a default
specified by Section 501 is intended to constitute an expense of administration
under any then applicable bankruptcy or insolvency law. "Trustee" for purposes
of this Section 606 shall include any predecessor Trustee but the negligence or
bad faith of any Trustee shall not affect the rights of any other Trustee under
this Section 606.

         The Company's obligations under this Section 606 and any lien hereunder
shall survive the resignation or removal of any Trustee, the discharge of the
Company's obligations pursuant to Article Four of this Indenture and the
termination of this Indenture.

             Section 607. Corporate Trustee Required; Eligibility.

         (1) There shall at all times be a Trustee hereunder that is a
Corporation, organized and doing business under the laws of the United States of
America, any state thereof or the District of Columbia, eligible under Section
310(a)(1) of the Trust Indenture Act to act as trustee under an indenture
qualified under the Trust Indenture Act and that has a combined capital and
surplus (computed in accordance with Section 310(a)(2) of the Trust Indenture
Act) of at least $50,000,000 subject to supervision or examination by Federal or
state authority. If at any time the Trustee shall cease to be eligible in
accordance with the provisions of this Section 607, it shall resign immediately
in the manner and with the effect hereinafter specified in this Article Six.

         (2) The following indenture shall be considered specifically described
herein for purposes of clause (i) of the proviso contained in Section 310(b)(1)
of the Trust Indenture Act; Indenture dated as of between [the Company] [the
Guarantor] and ______________, as successor trustee; and, pursuant to Section
310(b)(1)(C)(i) of the Trust Indenture Act, unless otherwise ordered by the
Commission, an event of default by the Company under this Indenture will not
disqualify the Trustee under this Indenture because it is a trustee under such
other indenture.

             Section 608. Resignation and Removal; Appointment of Successor.

         (a) No resignation or removal of the Trustee and no appointment of a
successor Trustee pursuant to this Article shall become effective until the
acceptance of appointment by the successor Trustee pursuant to 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 and the
Guarantor. If the instrument of acceptance by a successor Trustee required by
Section 609 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 with
respect to the Securities of such series.

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

         (d) If at any time:

<PAGE>

                  (i) the Trustee shall fail to comply with the obligations
         imposed upon it under Section 310(b) of the Trust Indenture Act with
         respect to Securities of any series after written request therefor by
         the Company, the Guarantor or any Holder of a Security of such series
         who has been a bona fide Holder of a Security of such series for at
         least six months; or

                  (ii) the Trustee shall cease to be eligible under Section 607
         and shall fail to resign after written request therefor by the Company,
         the Guarantor or any such Holder; or

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

then, in any such case, (A) the Company, by or pursuant to a Board Resolution,
may remove the Trustee with respect to all Securities or the Securities of such
series, or (B) subject to Section 315(e) of the Trust Indenture Act, 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 removal of the Trustee with
respect to all Securities of such series 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) and shall comply with
the applicable requirements of Section 609. 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 in accordance with the applicable requirements of Section
609, become the successor Trustee with respect to the Securities of such series
and to that extent supersede the successor Trustee appointed by the Company. If
no successor Trustee with respect to the Securities of any series shall have
been so appointed by the Company or the Holders of Securities and accepted
appointment in the manner required by Section 609, 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 the 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 by mailing
written notice of such event by first-class mail, postage prepaid, to the
Holders of Registered Securities, if any, of such series as their names and
addresses appear in the Security Register and, if Securities of such series are
issued as Bearer

                                       57
<PAGE>

Securities, by publishing notice of such event once in an Authorized Newspaper
in each Place of Payment located outside the United States. 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) Upon the appointment hereunder of any successor Trustee with
respect to all Securities, such successor Trustee so appointed shall execute,
acknowledge and deliver to the Company, the Guarantor and the retiring Trustee
an instrument accepting such appointment, and thereupon the resignation or
removal of the retiring Trustee shall become effective and such successor
Trustee, without any further act, deed or conveyance, shall become vested with
all the rights, powers, trusts and duties hereunder of the retiring Trustee;
but, on the request of the Company, the Guarantor or such successor Trustee,
such retiring Trustee, upon payment of its charges, shall execute and deliver an
instrument transferring to such successor Trustee all the rights, powers and
trusts of the retiring Trustee and, subject to Section 1003, 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) Upon the appointment hereunder of any successor Trustee with
respect to the Securities of one or more (but not all) series, the Company, the
Guarantor, the retiring Trustee and such successor Trustee shall execute and
deliver an indenture supplemental hereto wherein each successor Trustee shall
accept such appointment and which (1) shall contain such provisions as shall be
necessary or desirable to transfer and confirm to, and to vest in, such
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, 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 that no
Trustee shall be responsible for any notice given to, or received by, or any act
or failure to act on the part of any other Trustee hereunder, 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, such retiring Trustee shall have no further responsibility for the
exercise of rights and powers or for the performance of the duties and
obligations vested in the Trustee under this Indenture with respect to the
Securities of that or those series to which the appointment of such successor
Trustee relates other than as hereinafter expressly set forth, 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
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, the
Guarantor, or such successor Trustee, such retiring Trustee, upon payment of its
charges with respect to the Securities of that or those series to which the
appointment of such successor relates and subject to Section 1003 shall duly
assign, transfer and deliver to such successor Trustee, to the extent
contemplated by such

                                       58
<PAGE>

supplemental indenture, the 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, subject to its claim, if any,
provided for in Section 606.

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

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

                 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,
without the execution or filing of any paper or any further act on the part of
any of the parties hereto. In case any Securities shall have been authenticated
but not delivered by the Trustee then in office, any successor by merger,
conversion or consolidation to such authenticating Trustee may adopt such
authentication and deliver the Securities so authenticated with the same effect
as if such successor Trustee had itself authenticated such Securities.

                 Section 611. Appointment of Authenticating Agent.

         The Trustee may appoint one or more Authenticating Agents acceptable to
the Company with respect to one or more series of Securities which shall be
authorized to act on behalf of the Trustee to authenticate Securities of that or
those series issued upon original issue, exchange, registration of transfer,
partial redemption or partial repayment or pursuant to Section 306, and
Securities so authenticated shall be entitled to the benefits of this Indenture
and shall be valid and obligatory for all purposes as if authenticated by the
Trustee hereunder. Wherever reference is made in this Indenture to the
authentication and delivery of Securities by the Trustee or the Trustee's
certificate of authentication, such reference shall be deemed to include
authentication and delivery on behalf of the Trustee by an Authenticating Agent
and a certificate of authentication executed on behalf of the Trustee by an
Authenticating Agent.

         Each Authenticating Agent shall be acceptable to the Company and the
Guarantor and, except as provided in or pursuant to this Indenture, shall at all
times be a corporation that would be permitted by the Trust Indenture Act to act
as trustee under an indenture qualified under the Trust Indenture Act, is
authorized under applicable law and by its charter to act as an Authenticating
Agent and has a combined capital and surplus (computed in accordance with
Section 310(a)(2) of the Trust Indenture Act) of at least $50,000,000. If at any
time an Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section 611, it shall resign immediately in the manner and
with the effect specified in this Section 611.

                                       59
<PAGE>

         Any Corporation into which an Authenticating Agent may be merged or
converted or with which it may be consolidated, or any Corporation resulting
from any merger, conversion or consolidation to which such Authenticating Agent
shall be a party, or any Corporation succeeding to all or substantially all of
the corporate agency or corporate trust business of an Authenticating Agent,
shall be the successor of such Authenticating Agent hereunder, provided such
Corporation shall be otherwise eligible under this Section 611, without the
execution or filing of any paper or any further act on the part of the Trustee
or the Authenticating Agent.

         An Authenticating Agent may resign at any time by giving written notice
thereof to the Trustee, the Company and the Guarantor. The Trustee may at any
time terminate the agency of an Authenticating Agent by giving written notice
thereof to such Authenticating Agent, the Company and the Guarantor. 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 611, the Trustee may appoint a successor
Authenticating Agent which shall be acceptable to the Company and shall (i) mail
written notice of such appointment by first-class mail, postage prepaid, to all
Holders of Registered Securities, if any, of the series with respect to which
such Authenticating Agent shall serve, as their names and addresses appear in
the Security Register, and (ii) if Securities of the series are issued as Bearer
Securities, publish notice of such appointment at least once in an Authorized
Newspaper in the place where such successor Authenticating Agent has its
principal office if such office is located outside the United States. Any
successor Authenticating Agent, upon acceptance of its appointment hereunder,
shall become vested with all the rights, powers and duties of its predecessor
hereunder, with like effect as if originally named as an Authenticating Agent.
No successor Authenticating Agent shall be appointed unless eligible under the
provisions of this Section 611.

         The Company agrees to pay each Authenticating Agent from time to time
reasonable compensation for its services under this Section 611.

         The provisions of Sections 308, 603 and 604 shall be applicable to each
Authenticating Agent.

         If an Authenticating Agent is appointed with respect to one or more
series of Securities pursuant to this Section 611, 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 in
substantially the following form:

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

                                       Authorized Officer

         If all of the Securities of any series may not be originally issued at
one time, and if the Trustee does not have an office capable of authenticating
Securities upon original issuance located in a Place of Payment where the
Company wishes to have Securities of such series authenticated upon original
issuance, the Trustee, if so requested in writing (which writing need not be
accompanied by or contained in an Officers' Certificate by the Company), shall
appoint in accordance with this Section 611 an Authenticating Agent having an
office in a Place of Payment designated by the Company with respect to such
series of Securities.

assessments or governmental charges and any additional taxes, duties,
assessments or governmental charges payable in respect of such) in the payment
to each Holder of a Security of the amounts which would have been payable
pursuant to the Securities had no such withholding or deduction been required,
except that no Successor Additional Amounts shall be so payable for or on
account of:

                  (A) any tax, duty, levy, assessment or other governmental
         charge which would not have been imposed but for the fact that such
         Holder: (i) was a resident, domiciliary or national of, or engaged in
         business or maintained a permanent establishment or was physically
         present in, the jurisdiction of organization of such Successor or any

         ownership of, or receipt of payment under, such Security; (ii)
         presented (if presentation is required) such Security for payment in
         such jurisdiction or any of its territories or any political

         such Security more than thirty (30) days after the date on which the
         payment in respect of such Security first became due and payable or

         would have been entitled to such Successor Additional Amounts if it had
         presented such Security for payment on any day within such period of
         thirty (30) days; (iv)is not dealing with the Successor directly or

         in respect of) principal of or any premium or Interest on, such
         Securities;

                  (D) any tax, assessment or other governmental charge that is
         imposed or withheld by reason of the failure to comply by the Holder or
         the beneficial owner of the Security with a request of the Company or
         the Successor addressed to the Holder (i) to provide information
         concerning the nationality, residence or identity of the Holder or such
         beneficial owner or (ii) to make any declaration or other similar claim
         or satisfy any information or reporting requirement, which, in the case
         of (i) or (ii), is required or imposed by statute, treaty, regulation
         or administrative practice of the taxing jurisdiction as a precondition
         or exemption from all or part of such tax, assessment or other

by the laws of the jurisdiction of organization of such Person (or any political
subdivision or taxing authority thereof or therein) to be included in the income
for tax purposes of a beneficiary or settlor with respect to such fiduciary or a
member of such partnership or a beneficial owner who would not have been
entitled to such Successor Additional Amounts had it been the Holder of the
Security; and

         (4) the Company has delivered to the Trustee an Officers' Certificate
and an Opinion of Counsel, each stating that such consolidation, merger,
conveyance, transfer or lease and, if a supplemental indenture is required in
connection with such transaction, such supplemental indenture comply with this
Article and that all conditions precedent herein provided for relating to such
transaction have been complied with.

         (b) The Company may assign its obligations under any series of
Securities to any other Subsidiary (the "Subsidiary Assignee") and such
Subsidiary Assignee shall be treated as the Successor to the Company with
respect to such series of Securities, provided that the conditions set forth in
Section 802(a) that would apply to the merger of the Company into such
Subsidiary Assignee are satisfied.

                        Section 803. Successor Person Substituted for Company or
                                     Guarantor.

         Upon any consolidation by the Company or the Guarantor with or merger
of the Company or the Guarantor into any other Person or any conveyance,
transfer or lease of the properties and assets of the Company or the Guarantor,
as the case may be, as an entirety or substantially as an entirety to any Person
in accordance with Sections 801 or 802, the successor Person formed by such
consolidation or into which the Company or the Guarantor, as the case may be, is
merged or to which such conveyance, transfer or lease is made shall succeed to,
and be substituted for, and may exercise every right and power of, the Company
or the Guarantor, as the case may be, under this Indenture with the same effect
as if such successor Person had been named as the Company or the Guarantor, as
the case may be, herein; and thereafter, except in the case of a lease, the
predecessor Person shall be released from all obligations and covenants under
this Indenture, the Securities, the Guarantees and the Coupons.

                       Section 804. Assumption by the Guarantor of the Company's
                                    Obligations.

         (a) The Guarantor may, at its option, assume the obligations of the
Company as obligor under any series of Securities and this Indenture; provided
that:

         (i) the Guarantor expressly assumes in an assumption agreement or
supplemental indenture hereto, executed and delivered to the Trustee, in form
satisfactory to the Trustee, the due and punctual payment of the principal of
and any premium and Interest on such Securities and the performance or
observance of every covenant of this Indenture on the part of the Company to be
performed or observed (including any obligation to pay any Additional Amounts),
and which agreement or supplemental indenture shall provide for conversion or
exchange rights in accordance with the provisions of the Securities of the
applicable series;

                                       66
<PAGE>

         (ii) immediately after giving effect to such assumption, no Event of
Default and no event, which after notice or lapse of time or both, would become
an Event of Default, shall have occurred and be continuing; and

         (iii) the Guarantor shall expressly agree in an assumption agreement or
supplemental indenture hereto, executed and delivered to the Trustee, in form
satisfactory to the Trustee, to immediately indemnify (pursuant to the
indemnification procedure described in Section 805) the Holder of each Security
against (i) any tax, assessment or governmental charge imposed on such Holder or
required to be withheld or deducted from any payment to such Holder (including
any governmental charge or withholding tax attributable to the Guarantor
indemnifying such Holder) as a consequence of such assumption and (ii) any costs
or expenses of such assumption (except that if the Guarantor delivers to the
Trustee an opinion of an independent counsel or a tax consultant of recognized
standing that the Holders will not recognize income, gain or loss for U.S.
federal income tax purposes as a result of such assumption by the date of such
assumption, a Holder will have indemnification rights pursuant to the
indemnification procedure described in Section 805 only if and when gain for
U.S. federal income tax purposes is actually recognized by such Holder); and

         (iv) the Guarantor shall have delivered to the Trustee an Officers'
Certificate stating that such assumption and such assumption agreement or
supplemental indenture comply with this Article and that all conditions
precedent herein provided for relating to such assumption have been complied
with.

         (b) Upon any assumption pursuant to Section 804(a), the Guarantor shall
succeed to, and be substituted for, and may exercise every right and power of,
the Company under such Securities and this Indenture with the same effect as if
the Guarantor had been named as the Company herein, and the Company shall be
released from its liability as obligor upon the Securities and any Coupons and
under this Indenture.

                    Section 805. Indemnification Procedure.

         (a) If a transaction described above under Sections 801, 802 or 804 (an
"Indemnifiable Transaction") should constitute a taxable event for U.S. federal
income tax purposes, the Guarantor or any other Person that assumes the
obligations of the Guarantor or the Company pursuant to such Sections, as the
case may be, shall indemnify a Holder of a Security against any tax, assessment
or governmental charge imposed on such Holder or required to be withheld or
deducted from any payment to such Holder (including any governmental charge or
withholding attributable to an indemnification payment made by or on behalf of
the Guarantor or any such Person) and any other tax costs or other tax expenses
attributable to such Indemnifiable Transaction, and the Guarantor or any such
Person, as the case may be, shall comply with the following indemnification
procedures:

         (1) Unless the Guarantor or any such Person, as the case may be,
delivers to the Trustee by the date of an Indemnifiable Transaction an opinion
of an independent counsel or a tax consultant of recognized standing to the
effect that such Indemnifiable Transaction will not be a taxable event for U.S.
federal income tax purposes, the Guarantor or any such Person, as the case may
be, shall send to each Holder on or prior to the date of such Indemnifiable
Transaction (i)

                                       67
<PAGE>

notification explaining the U.S. federal income tax consequences to each such
Holder of such Indemnifiable Transaction and (ii) an indemnification claim form
requesting (A) information concerning each such Holder's tax basis and holding
period in a Security and (B) a statement that the Holder is not then an entity
described in Section 501 of the Internal Revenue Code, as amended from time to
time, that is exempt from U.S. federal income tax and (iii) a statement setting
forth the address to which each such Holder must remit such form.

         (2) If the Guarantor or any such Person delivers such an opinion, each
Holder will have indemnification rights pursuant to this Section 805 only if and
when gain for U.S. federal income tax purposes is actually recognized by such
Holder.

         (3) When the Guarantor or any such Person, as the case may be, receives
from a Holder an indemnification claim form, the Guarantor or such Person, as
the case may be, shall within 15 Business Days remit to such Holder a certified
check in an amount equal to the product of any gain recognized as a result of
the Indemnifiable Transaction and the highest marginal U.S. income tax rate in
effect at the time of such Indemnifiable Transaction (the "Indemnification
Amount"). For these purposes, a Holder's gain shall equal the amount by which
the fair market value of a Security at the time of such Indemnifiable
Transaction exceeds such Holder's adjusted tax basis in such Security.

Company (when authorized by or pursuant to a Board Resolution), the Guarantor
(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:

         (a) to evidence the succession of another Person to the Company or the
Guarantor, and the assumption by any such successor of the covenants of the
Company or the Guarantor, as the case may be, contained herein and in the
Securities or the Guarantees; or

         (b) to add to the covenants of the Company or the Guarantor for the
benefit of the Holders of all or any series of Securities (as shall be specified
in such supplemental indenture or indentures) or to surrender any right or power
herein conferred upon the Company or the Guarantor; or

         (c) 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, any premium or
Interest on or any Additional Amounts with respect to Securities, to permit
Bearer Securities to be issued in exchange for Registered Securities, to permit
Bearer Securities to be exchanged for Bearer Securities of other authorized
denominations or to permit or facilitate the issuance of Securities in
uncertificated form, provided any such action shall not adversely affect the
interests of the Holders of Securities of any series or any Coupons appertaining
thereto in any material respect; or

                                       68
<PAGE>

         (d) to establish the form or terms of Securities of any series and any

or

         (f) to cure any ambiguity or 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 adversely affect the interests of the
Holders of Securities of any series then Outstanding or any Coupons appertaining
thereto in any material respect; or

         (g) to add to, delete from or revise the conditions, limitations and
restrictions on the authorized amount, terms or purposes of issue,
authentication and delivery of Securities, as herein set forth; or

         (h) to add any additional Events of Default with respect to all or any
series of Securities (as shall be specified in such supplemental indenture); or

         (i) 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 Article Four, provided that
any such action shall not adversely affect the interests of any Holder of a
Security of such series and any Coupons appertaining thereto or any other
Security or Coupon in any material respect; or

         (j) to secure the Securities or the Guarantees; or

         (k) to make provisions with respect to conversion or exchange rights of
Holders of Securities of any series; or

         (l) to amend or supplement any provision contained herein or in any
supplemental indenture, provided that no such amendment or supplement shall
materially adversely affect the interests of the Holders of any Securities then
Outstanding.

          Section 902. Supplemental Indentures with Consent of Holders.

         With the consent of the Holders of not less than a majority in
principal amount of the Outstanding Securities of each series affected by such
supplemental indenture (and, in the case of any series of Securities held as
assets of a Trust, such consent of holders of the Preferred Securities and the
common securities of such Trust as may be required under the Trust Agreement of
such Trust), by Act of said Holders delivered to the Company and the Trustee,
the Company (when authorized by or pursuant to a Board Resolution), the
Guarantor (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

                                       69
<PAGE>

eliminating any of the provisions of this Indenture or of modifying in any
manner the rights of the Holders of Securities of such series under this
Indenture or of the Securities of such series; provided, however, that no such
supplemental indenture, without the consent of the Holder of each Outstanding
Security affected thereby, shall:

         (a) change the Stated Maturity of the principal of, or any premium or
installment of Interest on or any Additional Amounts with respect to, any
Security, as such Stated Maturity may be extended in accordance with the terms
of such Security or Coupon appertaining thereto, or reduce the principal amount
thereof or the rate (or modify the calculation of such rate) of Interest thereon
or any Additional Amounts with respect thereto, or any premium payable upon the
redemption thereof or otherwise, or change the duration of the maximum
consecutive period, if any, that payments of Interest on such Securities may be
deferred, if applicable, or change the obligation of the Company to pay
Additional Amounts pursuant to Section 1004 (except as contemplated by Section
801(a) and permitted by Section 901(a)), or reduce the amount of the principal
of an Original Issue Discount Security that would be due and payable upon a
declaration of acceleration of the Maturity thereof pursuant to Section 502 or
the amount thereof provable in bankruptcy pursuant to Section 504, change the

repayment at the option of any Holder as contemplated by Article Twelve or
change the subordination provisions that apply to the terms of such Securities
in a manner adverse to Holders, or change the Place of Payment, Currency in
which the principal of, any premium or Interest on, or any Additional Amounts
with respect to any Security is payable, or impair the right to institute suit
for the enforcement of any such payment on or after the Stated Maturity thereof
(or, in the case of redemption, on or after the Redemption Date or, in the case
of repayment at the option of the Holder, on or after the date for repayment or
in the case of change in control, after the Change in Control Purchase Date); or

         (b) reduce the percentage in principal amount of the Outstanding
Securities of any series, the consent of whose Holders is required for any such
supplemental indenture, or the consent of whose Holders is required for any
waiver (of compliance with certain provisions of this Indenture or certain
defaults hereunder and their consequences) provided for in this Indenture, or
reduce the requirements of Section 1404 for quorum or voting; or

         (c) modify or effect in any manner adverse to the Holders the terms and
conditions of the obligations of the Company under the Securities or the
Coupons, or the Guarantor under the Guarantees, or either of them hereunder, in
respect of the due and punctual payments of principal of, any premium or
Interest on, or any Additional Amounts with respect to, the Securities; or

         (d) modify any of the provisions of this Section 902, Section 513 or
Section 1008, except to increase any such percentage or to provide that certain
other provisions of this Indenture cannot be modified or waived without the
consent of the Holder of each Outstanding Security affected thereby; or

         (e) make any change that adversely affects the right to convert or
exchange any Security into or for Common Stock or other securities, cash or
property in accordance with its terms; or

                                       70
<PAGE>

         (f) modify any of the provisions of this Indenture relating to the
subordination of the Securities in a manner adverse to Holders of Securities.

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

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

               Section 903. Execution of Supplemental Indentures.

         As a condition to executing, or accepting the additional trusts created
by, any supplemental indenture permitted by this Article Nine or the
modifications thereby of the trust created by this Indenture, the Trustee shall
be entitled to receive (in addition to those documents required by Section 102),
and (subject to Section 315 of the Trust Indenture Act) 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. The Trustee
may, but shall not be obligated to, enter into any such supplemental indenture
which affects the Trustee's own rights, duties or immunities under this
Indenture or otherwise.

               Section 904. Effect of Supplemental Indentures.

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

               Section 905. Reference in Securities to Supplemental Indentures.

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

               Section 906. Conformity with Trust Indenture Act.

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

                  Section 907. Effect on Senior Indebtedness.

         No supplemental indenture shall directly or indirectly modify or
eliminate the provisions of Article Seventeen or Article Eighteen, as the case
may be, in any manner which might terminate or impair the subordination of the
Securities of any series to Company Senior Indebtedness with respect to such
series or the subordination of the Guarantee in respect thereof to Guarantor
Senior Indebtedness with respect to such series, respectively, without the prior
written consent of the holders of such Company Senior Indebtedness or Guarantor
Senior Indebtedness, respectively.

                                   ARTICLE TEN
                                    COVENANTS

                  Section 1001. Payment of Principal, any Premium and Interest.

         (1) The Company shall pay the principal of, any premium and Interest on
(including Interest accruing during any extension period and/or on or after the
filing of a petition in bankruptcy or reorganization relating to the Company,
whether or not a claim for post-filing Interest is allowed in such proceeding)
and any Additional Amounts with respect to the Securities on or prior to the
dates and in the manner provided in such Securities or pursuant to this
Indenture. An installment of principal, and any premium, Interest or Additional
Amounts shall be considered paid on the applicable due date if on such date the
Trustee or the Paying Agent holds, in accordance with this Indenture, money
sufficient to pay all of such installment then due. With respect to any
Security, the Company shall pay Interest on overdue principal and Interest on
overdue installments of Interest (including Interest accruing during any
extension period and/or on or after the filing of a petition in bankruptcy or
reorganization relating to the Company, whether or not a claim for post-filing
Interest is allowed in such proceeding), or Additional Amounts to the extent
lawful, at the rate accruing on such Security, compounded with the same
frequency as Interest is payable on such Securities. Interest on overdue
Interest shall accrue from the date such amounts become overdue.

         (2) Notwithstanding the provisions of Section 1001 (1) or any other
provision herein to the contrary, the Company shall have the right, as provided
in an Officer's Certificate or supplemental indenture issued pursuant to Article
Nine, in its sole and absolute discretion at any time and from time to time
while the Securities of any series are outstanding, so long as no Event of
Default with respect to such series of Securities has occurred and is
continuing, to defer payments of Interest by extending the Interest payment
period for such series of Securities for the maximum consecutive period, if any,
specified for such series of Securities, provided that such extension period
must end on an Interest Payment Date and shall not extend beyond the Stated
Maturity or Redemption Date of any Security of such series, and provided further
that at the end of each extension period the Company shall pay all Interest then
accrued and unpaid (together with Interest thereon to the extent permitted by
applicable law at the rate accruing on such Securities). Prior to the
termination of an extension period, the Company may shorten or may further
extend the Interest payment period for such series of Securities, provided that
such extension period together with all such previous and further extensions may
not exceed the maximum consecutive period specified for such series of
Securities, end on a date other than an Interest Payment Date or

                                       72
<PAGE>

extend beyond the Stated Maturity or Redemption Date of any Security of such
series. The Company shall give the Trustee notice of the Company's election to
begin an extension period for any series of Securities and any shortening or
extension thereof at least five Business Days prior to: (i) the date notice of
payment of Interest on such Securities is required to be given to any national
securities exchange on which the related Preferred Securities, if any, or
Securities are then listed or other applicable self-regulatory organization, or
(ii) the date of the notice of the record or payment date of the related
distribution on the Preferred Securities issued by the Trust which is the Holder
of the Securities of such series, but in any event not less than five Business
Days prior to the Record Date fixed by the Company for the payment of such
Interest. The Company shall give or cause the Trustee to give notice (a form of
which shall be provided by the Company to the Trustee) of the Company's election
to begin an extension period to the Holders by first class mail, postage
prepaid.

                 Section 1002. Maintenance of Office or Agency.

         The Company and the Guarantor shall maintain in each Place of Payment
for any series of Securities an Office or Agency where Securities of such
series, and Guarantees with respect thereto (but not Bearer Securities, except
as otherwise provided below, unless such Place of Payment is located outside the
United States), may be presented or surrendered for payment, where Securities of
such series may be surrendered for registration of transfer or exchange, where
Securities of such series may be presented and surrendered in the event of a
conversion or exchange, and where notices and demands to or upon the Company and
the Guarantor in respect of the Securities of such series relating thereto and
this Indenture may be served. If Securities of a series are issuable as Bearer
Securities, the Company and the Guarantor shall maintain, subject to any laws or
regulations applicable thereto, an Office or Agency in a Place of Payment for
such series which is located outside the United States where Securities of such
series and any Coupons appertaining thereto, and Guarantees with respect
thereto, may be presented and surrendered for payment; provided, however, that
if the Securities of such series are listed on The Stock Exchange of the United
Kingdom and the Republic of Ireland or the Luxembourg Stock Exchange or any
other stock exchange located outside the United States and such stock exchange
shall so require, the Company and the Guarantor shall maintain a Paying Agent
and a Conversion Agent, if applicable, in London, Luxembourg or any other
required city located outside the United States, as the case may be, so long as
the Securities of such series are listed on such exchange. The Company and the
Guarantor will give prompt written notice to the Trustee of the location, and
any change in the location, of such Office or Agency. If at any time the Company
and the Guarantor shall fail to maintain any such required Office or Agency or
shall fail to furnish the Trustee with the addresses thereof, such
presentations, surrenders, notices and demands may only be made or served at the
Corporate Trust Office of the Trustee, except that Bearer Securities of such
series and any Coupons appertaining thereto, and Guarantees with respect
thereto, may be presented and surrendered for payment at the place specified for
the purpose with respect to such Securities as provided in or pursuant to this
Indenture, and the Company and the Guarantor hereby appoint the Trustee as their
agent to receive all such presentations, surrenders, notices and demands.

         Except as otherwise provided in or pursuant to this Indenture, no
payment of principal, premium, Interest or Additional Amounts with respect to
Bearer Securities shall be made at any Office or Agency 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,

                                       73
<PAGE>

however, if amounts owing with respect to any Bearer Securities shall be payable
in Dollars, payment of principal of, any premium or Interest on and any
Additional Amounts with respect to any such Security, or the Guarantees with
respect thereto, may be made at the Corporate Trust Office of the Trustee or any
Office or Agency designated by the Company in the Borough of Manhattan, The City
of New York, if (but only if) payment of the full amount of such principal,
premium, Interest or Additional Amounts at all offices outside the United States
maintained for such purpose by the Company and the Guarantor in accordance with
this Indenture is illegal or effectively precluded by exchange controls or other
similar restrictions.

         The Company and the Guarantor may also from time to time designate one
or more other Offices or Agencies where the Securities of one or more series,
and the Guarantees endorsed thereon, may be presented or surrendered for any or
all 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 or the Guarantor of its obligation to maintain an Office or Agency in
each Place of Payment for Securities of any series for such purposes. The
Company and the Guarantor shall 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 provided in or pursuant to this
Indenture, the Company and the Guarantor hereby designate as the Place of
Payment for each series of Securities and the Guarantees endorsed thereon, the
Borough of Manhattan, The City of New York, and initially appoints the Corporate
Trust Office of the Trustee as the Company's or the Guarantor's Office or Agency
in the Borough of Manhattan, The City of New York for such purpose. The Company
and the Guarantor may subsequently appoint a different Office or Agency in the
Borough of Manhattan, The City of New York for the Securities of any series, and
the Guarantees endorsed thereon.

         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 this Indenture, then the Company
and the Guarantor 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 or the Guarantor, as the case may be, shall at any time
act as its own Paying Agent with respect to any series of Securities, it shall,
on or before each due date of the principal of, any premium or Interest on or
Additional Amounts with respect to any of the Securities of such series,
segregate and hold in trust for the benefit of the Persons entitled thereto a
sum in the 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 of, any premium or
Interest on or Additional Amounts so becoming due until such sums shall be paid
to such Persons or otherwise disposed of as herein provided, and shall promptly
notify the Trustee of its action or failure so to act.

         Whenever the Company or the Guarantor, as the case may be, shall have
one or more Paying Agents for any series of Securities, it shall, on or prior to
each due date of the principal of, any premium or Interest on or any Additional
Amounts with respect to any Securities of such series, deposit with any Paying
Agent a sum (in the Currency or Currencies described in

                                       74
<PAGE>

the preceding paragraph) sufficient to pay the principal of, any premium or
Interest on or Additional Amounts so becoming due, such sum to be held in trust
for the benefit of the Persons entitled thereto, and (unless such Paying Agent
is the Trustee) the Company or the Guarantor, as the case may be, will promptly
notify the Trustee of its action or failure so to act.

         The Company shall cause each Paying Agent for any series of Securities
other than the Trustee to execute and deliver to the Trustee an instrument in
which such Paying Agent shall agree with the Trustee, subject to the provisions
of this Section 1003, that such Paying Agent shall:

         (a) hold all sums held by it for the payment of the principal of, any
premium or Interest on or any Additional Amounts with respect to Securities of
such series in trust for the benefit of the Persons entitled thereto until such
sums shall be paid to such Persons or otherwise disposed of as provided in or
pursuant to this Indenture;

         (b) give the Trustee notice of any default by the Company or the
Guarantor (or any other obligor upon the Securities of such series) in the
making of any payment of principal, any premium or Interest on or any Additional
Amounts with respect to the Securities of such series; and

         (c) 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 or the Guarantor, as the case may be, 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 of the Company or the Guarantor
direct a Paying Agent to pay, to the Trustee all sums held in trust by the
Company, the Guarantor or such Paying Agent, such sums to be held by the Trustee
upon the same terms as those upon which such sums were held by the Company, the
Guarantor 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 herein or pursuant hereto, any money
deposited with the Trustee or any Paying Agent, or then held by the Company or
the Guarantor, as the case may be, in trust for the payment of the principal of,
any premium or Interest on or any Additional Amount with respect to any Security
of any series or any Coupon appertaining thereto and remaining unclaimed for two
years after such principal or any such premium or Interest or any such
Additional Amount shall have become due and payable shall be paid to the Company
or the Guarantor, as the case may be, on Company Request, or (if then held by
the Company or the Guarantor) shall be discharged from such trust; and the
Holder of such Security or any Coupon appertaining thereto, or Guarantees
endorsed thereon, shall thereafter, as an unsecured general creditor, look only
to the Company or the Guarantor (pursuant to the Guarantees) for payment
thereof, and all liability of the Trustee or such Paying Agent with respect to
such trust money, and all liability of the Company or the Guarantor (pursuant to
Guarantee) 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 in each Place of Payment for such series or to be mailed to
Holders of Registered Securities of such series, or both, notice that such money
remains unclaimed and that,

                                       75
<PAGE>

after a date specified therein, which shall not be less than 30 days from the
date of such publication or mailing nor shall it be later than two years after
such principal and any premium or Interest or Additional Amounts shall have
become due and payable, any unclaimed balance of such money then remaining will
be repaid to the Company or the Guarantor, as the case may be.

                        Section 1004. Additional Amounts.

         Except as otherwise specified pursuant to Section 301 for the Security
of any series, the Company and the Guarantor each agrees to pay to the Holder of
any such Security or any Coupon appertaining thereto Additional Amounts as
provided in or pursuant to this Indenture or such Securities. Whenever in this
Indenture there is mentioned, in any context, the payment of the principal of or
any premium or Interest on, or in respect of, any Security of any series or any
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 hereby or
pursuant hereto 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 provision
hereof shall not be construed as excluding Additional Amounts in those
provisions hereof where such express mention is not made.

         All payments of, or in respect of, principal of or any premium or
Interest on any Security of any series or any Coupon or the net proceeds
received on the sale or exchange of any Security of any series shall be made
without withholding or deduction for, or on account of, any present or future
taxes, duties, levies, assessments or governmental charges of whatever nature
imposed or levied by or on behalf of the Applicable Taxing Jurisdiction, unless
such taxes, duties, levies, assessments or governmental charges are required by
the Applicable Taxing Jurisdiction to be withheld or deducted. In that event,
the Company will pay such additional amounts of, or in respect of, principal of
or any premium or Interest on any Security of any series or any Coupon or the
net proceeds received on the sale, or exchange of any Security of any series
("Additional Amounts") as will result (after deduction of such taxes, duties,
levies, assessments or governmental charges and any additional taxes, duties,
levies, assessments or governmental charges payable in respect of such
Additional amounts) in the payment to the Holder of the Securities of such
series of the amounts that would have been payable in respect of such Securities
and no such withholding or deduction been required, except that no Additional
Amounts shall be so payable for or on account of:

         (a) any tax, duty, levy, assessment or other governmental charge that
     would not have been imposed but for the fact that such Holder:

               (i) was a resident, domiciliary or national of, or engaged in
         business or maintained a permanent establishment or was physically
         present in the Applicable Taxing Jurisdiction or otherwise had some
         connection with the Applicable Taxing Jurisdiction other than the mere
         ownership of such Security.

               (ii) presented (if presentation is required) such Security for
         payment in the Applicable Taxing Jurisdiction, unless such Security
         could not have been presented for payment elsewhere;

                                       76
<PAGE>

               (iii) presented (if presentation is required) such Security, as
         the case may be, more than thirty (30) days after the date on which the
         payment in respect of such Security first became due and payable or was
         provided for, whichever is later, except to the extent that the Holder
         would have been entitled to such Additional Amounts if it had presented
         such Security for payment on any days within such period of thirty (30)
         days;

               (iv) directly or indirectly is taken to be an associate of the
         Company (as "associate" is defined in Division 16F of the Income Tax
         Assessment Act 1936 of the Commonwealth of Australia (the "Tax Act")
         (but on the basis that sub paragraphs 159GZC(1)(a)(ii), (1)(b)(i) and
         (1)(d)(i) of the Tax Act do not apply)); or

               (v) entered into or participated in a scheme to avoid withholding
         tax of the Applicable Taxing Jurisdiction, being a scheme which the
         Company was neither a party to nor participated in, in respect of which
         the Australian Commissioner of Taxation has made a determination that
         Australian interest withholding tax is payable in respect of the
         amount;

         (b) any estate, inheritance, gift, sale, transfer, personal property or
     similar tax, assessment or other governmental charge;

         (c) any tax, assessment or other governmental charge that is payable
     otherwise than by withholding or deduction from payments of, or in respect
     of principal of or Interest on such Security;

         (d) any tax, assessment or other governmental charge that is imposed or
     withheld by reason of the failure to comply by the Holder or the beneficial
     owner of such Security with a request of the Company addressed to the
     Holder (i) to provide information concerning the nationality, residence or
     identity of the Holder or such beneficial owner or (ii) to make any
     declaration or other similar claim or satisfy any information or reporting
     requirement, which, in the case of (i) or (ii), is required or imposed by a
     statute, treaty, regulation or administrative practice of the Applicable
     Taxing Jurisdiction as a precondition to exemption from all or part of such
     tax assessment or other governmental charge; or

         (e) any combination of items (a), (b), (c) and (d);

nor shall Additional Amounts be paid with respect to any payment of the
principal of or any premium or Interest on any Security of any series or any
Coupon or the net proceeds received on the sale or exchange of any Security of
any series to any Holder who is a fiduciary or partnership or other than the
sole beneficial owner of such payment to the extent such payment would be
required by the laws of the Applicable Taxing Jurisdiction to be included in the
income for tax purposes of a beneficiary or settlor with respect to such
fiduciary or a member of such partnership or a beneficial owner who would not
have been entitled to such Additional Amounts had it been the Holder of such
Security.

         Except as otherwise provided in or pursuant to this Indenture or the
Securities of the applicable series, 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 such series of Securities (or if the Securities of
such series shall not bear Interest prior to Maturity, the first day on which a
payment of principal is made), and at least 10 days prior to each date of
payment of principal or Interest if there has been any change with respect to
the matters set forth in the below mentioned Officers' Certificate, the Company
or the Guarantor, as the case may be, shall furnish to the

                                       77
<PAGE>

Trustee and the principal Paying Agent or Paying Agents, if other than the
Trustee, an Officers' Certificate instructing the Trustee and such Paying Agent
or Paying Agents whether such payment of principal of and premium, if any, or
Interest on the Securities of such series shall be made to Holders of Securities
of such series or the Coupons appertaining thereto who are United States Aliens
or non-residents of the Applicable Taxing Jurisdiction without withholding for
or on account of any tax, assessment or other governmental charge described in
the Securities of such 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 or Coupons, and
the Company agrees to pay to the Trustee or such Paying Agent the Additional
Amounts required by the terms of such Securities. Each of the Company and the
Guarantor, jointly and severally, 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 1004.

             Section 1005. No Restriction on Indebtedness or Liens.

         Nothing in this Indenture or in the Securities shall in any way
restrict or prevent the Company, the Guarantor or any other Subsidiary from
issuing, assuming, guaranteeing or otherwise incurring or securing any
Indebtedness, or otherwise granting any Liens in respect thereof.

         For the purposes of this Section 1005, "Lien" shall mean, with respect
to any asset, any mortgage, lien, pledge, security interest or encumbrances of
any kind in respect of such asset, whether or not filed, recorded or otherwise
perfected under applicable law.

                       Section 1006. Corporate Existence.

         Subject to Articles Eight and Fifteen, each of the Company and the
Guarantor shall do or cause to be done all things necessary to preserve and keep
in full force and effect its corporate existence and that of each other
Subsidiary and their respective rights (charter and statutory) and franchises;
provided, however, that the foregoing shall not obligate the Company, the
Guarantor or any other Subsidiary to preserve any such right or franchise if the
Company, the Guarantor or any other Subsidiary shall determine that the
preservation thereof is no longer desirable in the conduct of its business or
the business of such other Subsidiary.

                Section 1007. Payment of Expenses of Each Trust.

         The Company covenants for the benefit of the Holders of each series of
Securities owned by a Trust to pay all of the obligations, costs and expenses of
such Trust (other than payments in respect of Trust Securities) in accordance
with the provisions of its Trust Agreement and to pay the taxes of such Trust in
accordance with the provisions of its Trust Agreement in order to permit such
Trust to make distributions on and redemptions of its Preferred Securities in
accordance with its Trust Agreement.

                     Section 1008. Waiver of Certain Covenants.

         The Company or the Guarantor, as the case may be, may omit in any
particular instance to comply with any term, provision or condition set forth in
Sections 1001(2)or 1006 with respect to the Securities of any series if before
the time for such compliance the Holders of at least a majority in principal
amount of the Outstanding Securities of such series, by Act of such Holders,
either shall waive such compliance in such instance or generally shall have
waived compliance with such term, provision or condition, but no such waiver
shall extend to or affect such term, provision or condition except to the extent
so expressly waived, and, until such waiver shall become effective, the
obligations of the Company and the Guarantor and the duties of the Trustee in
respect of any such term, provision or condition shall remain in full force and
effect.

                     Section 1009. Company Statement as to Compliance; Notice of
                                   Certain Defaults.

         (a) Each of the Company and the Guarantor shall deliver to the Trustee,
within 120 days after the end of each fiscal year, a written statement (which
need not be contained in or accompanied by an Officers' Certificate) signed by
the principal executive officer, the principal financial officer or the
principal accounting officer of the Company and the Guarantor, respectively,
stating that

             (1) a review of the activities of the Company or the Guarantor, as
     the case may be, during such year and of its performance under this
     Indenture has been made under his or her supervision, and

             (2) to the best of his or her knowledge, based on such review, (i)
     the Company or the Guarantor, as the case may be, has complied with all the
     conditions and covenants imposed on it under this Indenture throughout such
     year, or, if there has been a default in the fulfillment of any such
     condition or covenant, specifying each such default known to him or her and
     the nature and status thereof, and (ii) no event has occurred and is
     continuing which is, or after notice or lapse of time or both would become,
     an Event of Default, or, if such an event has occurred and is continuing,
     specifying each such event known to him and the nature and status thereof.

         (b) Each of the Company and the Guarantor shall deliver to the Trustee,
within five days after the occurrence thereof, written notice of any Event of
Default or any Default.

                                 ARTICLE ELEVEN

                            REDEMPTION OF SECURITIES

                     Section 1101. Applicability of Article.

         Redemption of Securities of any series at the option of the Company as
permitted or required by the terms of such Securities shall be made in
accordance with the terms of such Securities and (except as otherwise provided
herein or pursuant hereto) this Article Eleven.

<PAGE>

                       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 or an Officers' Certificate. In case of any
redemption at the election of the Company of (a) less than all of the Securities
of any series or (b) all of the Securities of any series, with the same issue
date, Interest rate or formula, Stated Maturity and other terms, the Company
shall, at least 60 days prior to the Redemption Date fixed by the Company
(unless a shorter notice shall be satisfactory to the Trustee), notify the
Trustee of such Redemption Date and of the principal amount of Securities of
such series to be redeemed.

                       Section 1103. Selection by Trustee of Securities to be
                                     Redeemed.

         If less than all of the Securities of any series with the same issue
date, Interest rate or formula, Stated Maturity and other 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 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 of the principal amount of Registered
Securities of such series; provided, however, that no such partial redemption
shall reduce the portion of the principal amount of a Registered Security of
such series not redeemed to less than the minimum denomination for a Security of
such series established herein or pursuant hereto.

         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 Securities redeemed or to be redeemed only in part, to the
portion of the principal of such Securities which has been or is to be redeemed.

         Unless otherwise specified in or pursuant to this Indenture or the
Securities of any series, if any Security selected for partial redemption is
converted or exchanged for Common Stock or other securities, cash or property in
part before termination of the conversion or exchange right with respect to the
portion of the Security so selected, the converted or exchanged portion of such
Security shall be deemed (so far as may be) to be the portion selected for
redemption. Securities which have been converted or exchanged during a selection
of Securities to be redeemed shall be treated by the Trustee as Outstanding for
the purpose of such selection.

                       Section 1104. Notice of Redemption.

         Notice of redemption shall be given in the manner provided in Section
106, not less than 30 nor more than 60 days prior to the Redemption Date, unless
a shorter period is specified in the Securities to be redeemed, to the Holders
of Securities to be redeemed. Failure to give notice by mailing in the manner
herein provided to the Holder of any Registered Securities 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 Securities or portion thereof.

                                       80
<PAGE>

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

         All notices of redemption shall state:

         (a) the Redemption Date;

         (b) the Redemption Price;

         (c) 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;

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

         (e) that, on the Redemption Date, the Redemption Price shall become due
and payable upon each such Security or portion thereof to be redeemed, and, if
applicable, that Interest thereon shall cease to accrue on and after said date;

         (f) the place or places 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 any accrued Interest and Additional Amounts pertaining thereto;

         (g) 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 and any
Paying Agent is furnished;

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

         (i) that the redemption is out of a sinking fund, if such is the case;

         (j) in the case of Securities of any series that are convertible or
exchangeable into other securities, cash or property or rights, the conversion
or exchange price or rate, the date or dates on which or the period or periods
during which the right to convert or exchange the principal of the Securities of
such series to be redeemed will commence or terminate and the place or places
where such Securities may be surrendered for conversion or exchange; and

                                       81
<PAGE>

         (k) the CUSIP number or the Euroclear or the Clearstream Luxembourg
reference numbers of such Securities, if any (or any other numbers used by a
Depositary to identify such Securities).

         A notice of redemption mailed as contemplated by Section 106 need not
identify particular Registered Securities to be redeemed.

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

                   Section 1105. Deposit of Redemption Price.

         On or prior to 10:00 a.m., New York City time, on any Redemption Date,
the Company shall deposit, with respect to the Securities of any series called
for redemption pursuant to Section 1104, 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 applicable Currency
sufficient to pay the Redemption Price of, and (except if the Redemption Date
shall be an Interest Payment Date, unless otherwise specified pursuant to
Section 301 or in the Securities of such series) any accrued Interest on and
Additional Amounts with respect thereto, all such 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, and from and after such date (unless the
Company shall default in the payment of the Redemption Price and accrued
Interest) such Securities shall cease to bear Interest 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 any accrued Interest
and Additional Amounts to the Redemption Date; provided, however, that, except
as otherwise provided in or pursuant to this Indenture or the Bearer Securities
of such series, installments of Interest on Bearer Securities whose Stated
Maturity is on or prior to the Redemption Date shall be payable only upon
presentation and surrender of Coupons for such Interest (at an Office or Agency
located outside the United States except as otherwise provided in Section 1002),
and provided, further, that, except as otherwise specified in or pursuant to
this Indenture or the Registered Securities of such series, 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
Regular Record Dates therefor 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

                                       82
<PAGE>

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 any Interest or Additional
Amounts represented by Coupons shall be payable only upon presentation and
surrender of those Coupons at an Office or Agency for such Security located
outside of the United States except as otherwise provided in Section 1002.

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

                   Section 1107. Securities Redeemed in Part.

         Any Registered Security which is to be redeemed only in part shall be
surrendered at any Office or Agency for such Security (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, the Guarantees of the Guarantor shall be endorsed on and the Trustee
shall authenticate and deliver to the Holder of such Security without service
charge, a new Registered Security or Securities of the same series, containing
identical terms and provisions, of any authorized denomination as requested by
such Holder in aggregate principal amount equal to and in exchange for the
unredeemed portion of the principal of the Security so surrendered. If a
Security in global form is so surrendered, the Company shall execute, and the
Trustee shall authenticate and deliver to the U.S. Depositary or other
Depositary for such Security in global form as shall be specified in the Company
Order with respect thereto to the Trustee, without service charge, a new
Security in global form in a denomination equal to and in exchange for the
unredeemed portion of the principal of the Security in global form so
surrendered.

                    Section 1108. Redemption for Tax Reasons

         Except as otherwise specified pursuant to Section 301 for the
Securities of any series, if, as a result of any change in or any amendment to
the laws, regulations or published tax rulings of the Applicable Taxing
Jurisdiction affecting taxation, or any change in the official administration,
application or interpretation of such laws, regulations or published tax rulings
either generally or in relation to the Securities of any series, which change or
amendment becomes effective on or after the original issue date of such
Securities or which change in official administration, application or
interpretation shall not have been available to the public prior to such issue
date, it is determined by the Company that (a) the Company would be required to
pay any Additional Amounts pursuant to this Indenture in respect of any payments
that it may be required to make with respect to such Securities and (b) such
obligation cannot be avoided by the Company or the Guarantor taking reasonable
measures available to it, the Company may, at its option, redeem all (but not
less than all) of the Securities of such series upon not less than 30 nor more
than 60 days' written notice as provided in this Indenture, at a Redemption
Price equal to 100% of the principal amount thereof plus accrued and unpaid
Interest to the date fixed for

                                       83
<PAGE>

redemption; provided, however, that (x) no such notice of redemption may be
given earlier than 60 days prior to the earliest date on which the Company would
be obligated to pay such Additional amounts were a payment then due in respect
of such Securities and (y) at the time any such redemption notice is given, such
obligation to pay such Additional Amounts must remain in effect.

         If (a) the Company shall have on any date (the "Succession Date")
consolidated with or merged into, or conveyed or transferred or leased its
properties and assets as an entirety or substantially as an entirety to, any
Successor which is organized under the laws of any jurisdiction other than the
United States of America, any State thereof or the District of Columbia or the
jurisdiction in which the Company is organized, (b) as result of any change in
or any amendment to the laws, regulations or published tax rulings of such
jurisdiction, or of any political subdivision or taxing authority thereof or
therein, affecting taxation, or any change in the official administration,
application or interpretation of such laws, regulations or published tax rulings
either generally or in relation to such Securities, which change or amendment
become effective on or after the Succession Date or which change in official
administration, application or interpretation shall not have been available to
the public prior to such Succession Date and is notified to the Company, such
Successor would be required to pay any Successor Additional Amounts pursuant to
the Indenture or the terms of such Securities in respect of any payments that it
may be required to make with respect to such Securities and (c) such obligation
cannot be avoided by the Company or such Successor taking reasonable measures
available to it, the Company or such Successor may at its option redeem all (but
not less than all) of such Securities, upon not less than 30 nor more than 60
days' written notice as provided in this Indenture, at a Redemption Price equal
to 100% of the principal amount thereof plus accrued Interest to the date fixed
for redemption; provided however, that (a) no such notice of redemption may be
given earlier than 60 days prior to the earliest date on which a Successor would
be obligated to pay such Successor Additional Amounts were a payment then due in
respect of such Securities, and (b) at the time any such redemption notice is
given, such obligation to pay such Successor Additional Amounts must remain in
effect.

                       REPAYMENT AT THE OPTION OF HOLDERS

                    Section 1201. Applicability of Article.

         Securities of any series which are repayable at the option of the
Holders thereof before their Stated Maturity shall be repaid in accordance with
the terms of the Securities of such series. The repayment of any principal
amount of Securities pursuant to such option of the Holder to require repayment
of Securities before their Stated Maturity, for purposes of Section 309, shall
not operate as a payment, redemption or satisfaction of the Indebtedness
represented by such Securities unless and until the Company, at its option,
shall deliver or surrender the same to the Trustee with a directive that such
Securities be canceled. Notwithstanding anything to the contrary contained in
this Section 1201, in connection with any repayment of Securities, the Company
may arrange for the purchase of any Securities by an agreement with one or more
investment bankers or other purchasers to purchase such Securities by paying to
the Holders of such Securities on or

                                       84
<PAGE>
before the close of business on the repayment date an amount not less than the
repayment price payable by the Company on repayment of such Securities, and the
obligation of the Company to pay the repayment price of such Securities shall be
satisfied and discharged to the extent such payment is so paid by such
purchasers.

                                ARTICLE THIRTEEN

                        SECURITIES IN FOREIGN CURRENCIES

                    Section 1301. Applicability of Article.

         Whenever this Indenture provides for (i) any action by, or the
determination of any of the rights of, Holders of Securities of any series in
which not all of such Securities are denominated in the same Currency, or (ii)
any distribution to Holders of Securities, in the absence of any provision to
the contrary in the form of Security of any particular series or pursuant to
this Indenture or the Securities, any amount in respect of any Security
denominated in a Currency other than Dollars shall be treated for any such
action or distribution as that amount of Dollars that could be obtained for such
amount on such reasonable basis of exchange and as of the record date with
respect to Registered Securities of such series (if any) for such action,
determination of rights or distribution (or, if there shall be no applicable
record date, such other date reasonably proximate to the date of such action,
determination of rights or distribution) as the Company or the Guarantor may
specify in a written notice to the Trustee or, in the absence of such written
notice, as the Trustee may determine.

                        MEETINGS OF HOLDERS OF SECURITIES

                    Section 1401. Purposes for Which Meetings May Be Called.

         A meeting of Holders of Securities of any series may be called at any
time and from time to time pursuant to this Article Fourteen to make, give or
take any request, demand, authorization, direction, notice, consent, waiver or
other Act provided by this Indenture to be made, given or taken by Holders of
Securities of such series.

                    Section 1402. Call, Notice and Place of Meetings.

of any series for any purpose specified in Section 1401, to be held at such time
and at such place in the Borough of Manhattan, The City of New York, or, if
Securities of such series have been issued in whole or in part as Bearer
Securities, in London or in such place outside the United States as the Trustee
shall determine. Notice of every meeting of Holders of Securities of any series,
setting forth the time and the place of such meeting and in general terms the
action proposed to be taken at such meeting, shall be given, in the manner
provided in Section 106, not less than 21 nor more than 180 days prior to the

         (b) In case at any time the Company or the Guarantor (in each case, by

amount of the

                                       85
<PAGE>

Section 1401, by written request setting forth in reasonable detail the action
proposed to be taken at the meeting, and the Trustee shall not have mailed
notice of or made the first publication of the notice of such meeting within 21
days after receipt of such request (whichever shall be required pursuant to

time and the place in the Borough of Manhattan, The City of New York, or, if
Securities of such series are to be issued as Bearer Securities, in London for

                          Section 1403. Persons Entitled to Vote at Meetings.

case, the meeting may be adjourned for a period of not less than 10 days as
determined by the chairman of the meeting prior to the adjournment of such
meeting. In the absence of a quorum at any such adjourned meeting, such
adjourned meeting may be further adjourned for a period of not less than 10 days
as determined by the chairman of the meeting prior to the adjournment of such
adjourned meeting. Notice of the reconvening of any adjourned meeting shall be
given as provided in Section 1402(1), except that such notice need be given only

to be reconvened. Notice of the reconvening of an adjourned meeting shall state
expressly the percentage, as provided above, of the principal amount of the
Outstanding Securities of such series which shall constitute a quorum.

         Except as limited by the proviso to Section 902, any resolution
presented to a meeting or adjourned meeting duly reconvened at which a quorum is
present as aforesaid may be adopted only by the affirmative vote of the Holders
of a majority in principal amount of the Outstanding Securities of that series;
provided, however, that, except as limited by the proviso to Section 902, any
resolution with respect to any consent or waiver which this Indenture expressly

                                       86
<PAGE>

provides may be given by the Holders of at least 66-2/3% in principal amount of

which this Indenture expressly provides may be made, given or taken by the
Holders of a specified percentage, which is less than a majority, in principal
amount of the Outstanding Securities of a series may be adopted at a meeting or
an adjourned meeting duly reconvened and at which a quorum is present as

         Any resolution passed or decision taken at any meeting of Holders of
Securities of any series duly held in accordance with this Section 1404 shall be
binding on all the Holders of Securities of such series and the Coupons
appertaining thereto, whether or not such Holders were present or represented at
the meeting.

                       Section 1405. Determination of Voting Rights; Conduct and
                                     Adjournment of Meetings.

         (a) Notwithstanding any other provisions of this Indenture, the Trustee
may make such reasonable regulations as it may deem advisable for any meeting of
Holders of Securities of such 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, the Guarantor or Holders of Securities as provided in Section 1402(b),
in which case the Company or the Holders of Securities of the series calling the
meeting, as the case may be, shall in like manner appoint a temporary chairman.
A permanent chairman and a permanent secretary of the meeting shall be elected
by vote of the Persons entitled to vote a majority in principal amount of the
Outstanding Securities of such series represented at the meeting.

         (c) At any meeting, each Holder of a Security of such series or proxy
shall be entitled to one vote for each $1,000 principal amount of 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

                                       87
<PAGE>

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 1402 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 1406. 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 triplicate of all votes cast at the meeting. A record, at least in
triplicate, 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 facts setting forth a copy of the notice of the meeting and
showing that said notice was given as provided in Section 1402 and, if
applicable, Section 1404. 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, another to the Guarantor 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.

                                       89
<PAGE>

requires. The notice shall include or transmit a form of Change in Control

state:

         (a) the events causing a Change in Control and the date of such Change
in Control;

an integral multiple thereof; and

         (c) that such Security or Securities shall be purchased on the Change
in Control Purchase Date pursuant to the terms and conditions specified in the
Securities.

         The delivery of the Security, by hand or by registered mail prior to,
on or after the Change in Control Purchase Date (together with all necessary
endorsements), to the Trustee or to an Office or Agency shall be a condition
precedent to the obligation of the Company to pay to the Holder the Change in
Control Purchase Price therefor; provided, however, that such Change in Control
Purchase Price shall be so paid pursuant to this Section 1501 only if the
Security so

                                       90

Purchase Date, as the case may be, with respect to such Security (provided the
conditions in Section 1501(3), as applicable, have been satisfied) and (y) the
time of delivery of such Security to the Trustee or to an Office or Agency by
the Holder thereof in the manner required by Section 1501(3), as applicable.

         A Change in Control Purchase Notice may be withdrawn by means of a
written notice of withdrawal delivered to the office of the Trustee or to an
Office or Agency at any time prior to the close of business on the Change in
Control Purchase Date, specifying:

         (a) the certificate number or numbers of the Security or Securities,
except in the case of global Securities, in respect of which such notice of
withdrawal is being submitted;

         (b) the principal amount of the Security or Securities with respect to
which such notice of withdrawal is being submitted; and

         (c) the principal amount, if any, of such Security or Securities which
remains subject to the original Change in Control Purchase Notice, and which has
been and will be delivered for purchase by the Company.

         There shall be no purchase of any Securities pursuant to Section 1501
if there has occurred and in continuing an Event of Default (other than a
default in the payment of the Change in Control Purchase Price).

           Section 1503. Deposit of Change in Control Purchase Price.

         Prior to 12:00 noon, New York, New York time, on the Business Day
following the Change in Control Purchase Date, the Company shall deposit with
the Trustee (or, if the Guarantor or a Subsidiary or an Affiliate of any of them
is acting as Paying Agent, shall segregate and hold in trust as provided in
Section 1003) an amount of cash in immediately available funds or securities, if
expressly permitted hereunder, sufficient to pay the aggregate Change in Control
Purchase Price of all the Securities or portions thereof which are to be
purchased. If a deposit is made with the Trustee of the aforesaid amount of cash
or securities, the Securities or portions thereof with respect

                                       91
<PAGE>

to which a Change in Control Purchase Notice has been delivered and not validly
withdrawn shall become due and payable as of the Business Day following the
applicable Change in Control Purchase Date, and on and after such date Interest
payable in respect of such Securities shall cease and all other rights of the
Holders thereof shall terminate, other than the right to receive the Change in
Control Purchase Price upon delivery of such Securities to the Trustee.

               Section 1504. Covenant to Comply With Securities Laws Upon
                             Purchase of Securities.

         In connection with any purchase of Securities under Section 1501
hereof, the Company and the Guarantor shall (a) comply with Rule 13e-4 under the
Exchange Act of 1934, if applicable, (b) file the related Schedule 13E-4 (or any
successor schedule, form or report) under the Exchange Act of 1934, if
applicable, and (c) otherwise comply with all Federal and state Securities laws
regulating the purchase of the Securities (including positions of the Commission
under applicable no-action letters) so as to permit the rights and obligation
under Section 1501 to be exercised in the time and in the manner specified in
Section 1501 and 1502.

               Section 1505. Repayment to the Company.

         The Trustee shall return to the Company any cash, together with
Interest or dividends, if any, thereon (subject to the provisions of Section
605) held by it for the payment of the Change in Control Purchase Price of the
Securities that remain unclaimed as provided in the Securities; provided,
however, that to the extent the aggregate amount of cash deposited by the
Company pursuant to Section 1503 exceeds the aggregate Change in Control
Purchase Price of the Securities or portions thereof to be purchased, then
promptly after the Change in Control Purchase Date, the Trustee shall return any
such excess to the Company together with Interest or dividends, if any, thereon
(subject to the provisions of Section 605).

                                 ARTICLE SIXTEEN

                                   GUARANTEES

               Section 1601. Guarantee.

         The Guarantor hereby irrevocably and unconditionally guarantees to each
Holder of a Security authenticated and delivered by the Trustee, and to the
Trustee on behalf of such Holder, the due and punctual payment of the principal
of and any premium and Interest on and any Additional Amounts with respect to
such Security and the due and punctual payment of any payments provided for
pursuant to the terms of such Security and any Coupons appertaining thereto,
when and as the same shall become due and payable, whether at the Stated
Maturity, by declaration of acceleration, call for redemption or repayment or
otherwise, in accordance with the terms of such Security, any such Coupons and
this Indenture, and any and all other amounts owed by the Company to the Trustee
or the Holders under the terms of this Indenture. This guarantee will not be
discharged with respect to any Securities of any series or Coupons appertaining
thereto except by payment in full of the principal thereof, premium, if any, and
Interest thereon and all other amounts payable thereunder and under this
Indenture with respect thereto. The Guarantor hereby expressly waives its right
to require the Trustee or any Holder to pursue or exhaust its legal

                                       92
<PAGE>

or equitable remedies against the Company prior to exercising its rights under
this guarantee. In case of the failure of the Company punctually to make any
such payment, the Guarantor hereby agrees to cause such payment to be made
punctually when and as the same shall become due and payable, whether at the
Stated Maturity or by declaration of acceleration, call for redemption or
repayment or otherwise, and as if such payment were made by the Company.

         The Guarantor hereby agrees that any amounts to be paid by it hereunder
shall be paid without deduction or withholding for or on account of any and all
present or future tax, duty, assessment or governmental charge imposed upon or
as a result of such payment by the Government of the United States, or any state
or other political subdivision or taxing authority thereof or therein, or if
deduction or withholding of any such tax, duty, assessment or charge shall at
any time be required by or on behalf of the Government of the United States or
any such state, political subdivision or taxing authority, the Guarantor shall
pay such additional amount in respect of principal, premium, if any, and
Interest, if any, as may be necessary in order that the net amounts paid to the
Holder of a Security or the Trustee on behalf of the Holder of such Security, as
the case may be, pursuant to this guarantee after such deduction or withholding
shall not be less than the amount provided for in such Security to be then due
and payable; except that no such additional amount shall be payable in respect
of any Security to any Holder (a) who is subject to such tax, duty, assessment
or governmental charge in respect of such Security by reason of his being
connected with the United States otherwise than merely by the holding or
ownership of such Security, or (b) who is not dealing at arm's length with the
Guarantor (within the meaning of the Internal Revenue Code, as amended from time
to time).

         The Guarantor hereby agrees that its obligations hereunder shall be as
if it were principal debtor and not merely surety, and shall be absolute and
unconditional, irrespective of the validity, regularity or enforceability of any
Security or this Indenture, the absence of any action to enforce the same, any
waiver or consent by the Holder of such Security or by the Trustee with respect
to any provisions thereof or of this Indenture, the obtaining of any judgment
against the Company or any action to enforce the same or any other circumstances
which might otherwise constitute a legal or equitable discharge or defense of a
guarantor. The Guarantor hereby waives the benefits of division and discussion,
diligence, presentment, demand of payment, filing of claims with a court in the
event of merger, insolvency or bankruptcy of the Company, any right to require a
proceeding first against the Company, protest or notice with respect to any
Security or the indebtedness evidenced thereby and all demands whatsoever, and
covenants that no guarantee (including any Guarantee endorsed on a Security)
will be discharged in respect of any Security except by complete performance of
the obligations contained in such Security and in this guarantee. The Guarantor
hereby agrees that, in the event of a default in payment of principal (or
premium, if any) or Interest, if any, on or Additional Amounts with respect to
any Security, or a default in any payment referred to therein, legal proceedings
may be instituted by the Trustee on behalf of, or by, the Holder of such
Security, on the terms and conditions set forth in this Indenture, directly
against the Guarantor to enforce this guarantee without first proceeding against
the Company.

         The Guarantor shall be subrogated to all rights of the Holders of the
Securities of a particular series against the Company in respect of any amounts
paid by the Guarantor on account of such Securities pursuant to the provisions
of this guarantee or this Indenture; provided, however, that the Guarantor shall
not be entitled to enforce or to receive any payments arising out of, or

                                       93
<PAGE>

based upon, such right of subrogation until the principal of, any premium and
Interest on, and Additional Amounts with respect to, all Securities of such
series issued hereunder shall have been paid in full.

                         Section 1602. Execution and Delivery of Guarantees.

         The Guarantees to be endorsed on the Securities of each series shall
include the terms of the guarantee set forth in Section 202 (except that
references to premium and Interest need be included only if any premium or
Interest, respectively, is provided for in the terms of such series) and any
other terms that may be set forth in the form established pursuant to Section
202 with respect to such series. The Guarantor hereby agrees to execute the
Guarantees, in a form established pursuant to Section 202, to be endorsed on
each Security authenticated and delivered by the Trustee.

         The Guarantees shall be executed on behalf of the Guarantor by its
Chairman of the Board, a Vice Chairman of the Board, its President or one of its
Vice Presidents, under its corporate seal reproduced thereon attested by its
Secretary or one of its Assistant Secretaries. The signature of any of these
officers on the Guarantees may be manual or facsimile.

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

         The delivery of any Security by the Trustee, after the authentication
thereof hereunder, shall constitute due delivery of the Guarantee endorsed
thereon on behalf of the Guarantor. The Guarantor hereby agrees that its
Guarantee set forth in Section 202 and in this Article shall remain in full
force and effect notwithstanding any failure to endorse a Guarantee on any
Security.

         The Guarantees shall continue to be effective or be reinstated, as the
case may be, if at any time payment on any Security, in whole or in part, is
rescinded or must otherwise be restored to the Company or the Guarantor upon the
bankruptcy, liquidation or reorganization of the Company or the Guarantor or
otherwise.

                                ARTICLE SEVENTEEN

                           SUBORDINATION OF SECURITIES

                         Section 1701. Securities Subordinated to Company Senior
                                       Indebtedness.

                  Notwithstanding the provisions of Section 506 or any other
provision herein or in any Security, the Company and the Trustee and, by their
acceptance thereof, the Holders of the Securities (a) covenant and agree that
all payments by the Company of the principal of and any premium or Interest on
and any Additional Amounts with respect to the Securities (other than Securities
which have been discharged pursuant to Article Four or Securities that provide
for a sinking fund pursuant to the Board Resolution, Officers' Certificate or
supplemental indenture

                                       94
<PAGE>

establishing the series as to which such sinking fund is applicable) shall be
subordinated in accordance with the provisions of this Article Seventeen in
right of payment to the prior payment in full, in cash or cash equivalents, of
all amounts payable on, under or in connection with Company Senior Indebtedness,
and (b) acknowledge that holders of Company Senior Indebtedness are or shall be
relying on this Article Seventeen. Nothing herein or in any Security is intended
to or shall limit the amount of Company Senior Indebtedness the Company may
incur.

               Section 1702. Priority and Payment of Proceeds in Certain Events:
                             Remedies Standstill.

         (1) Upon any payment or distribution of assets or securities of the
Company, as the case may be, of any kind or character, whether in cash, property
or securities, upon any dissolution or winding up or total or partial
liquidation or reorganization of the Company, whether voluntary or involuntary,
or in bankruptcy, insolvency, receivership or other proceedings, all amounts
payable on, under or in connection with Company Senior Indebtedness (including
any Interest accruing on such Company Senior Indebtedness subsequent to the
commencement of a bankruptcy, insolvency, receivership or similar proceeding)
shall first be paid, ratably according to the aggregate amounts remaining unpaid
on account of the principal of and any premium and Interest on the Company
Senior Indebtedness held or represented by each, to the extent necessary to make
payment in full of all Company Senior Indebtedness remaining unpaid, in cash, or
payment provided for in cash or cash equivalents, ratably according to the
aggregate amounts remaining unpaid on account of the principal of and any
premium and Interest on the Company Senior Indebtedness held or represented by
each, to the extent necessary to make payment in full of all Company Senior
Indebtedness remaining unpaid, before the Holders or the Trustee on behalf of
the Holders or the holders of Preferred Securities, if any, shall be entitled to
receive from the Company any payment of principal of or any premium or Interest
on or Additional Amounts with respect to the Securities or distribution of any
assets or securities.

         (2) No direct or indirect payment by or on behalf of the Company of
principal of or any premium or Interest on or Additional Amounts with respect to
the Securities (other than Securities which have been discharged pursuant to
Article Four or Securities that provide for a sinking fund), whether pursuant to
the terms of the Securities or upon acceleration or otherwise, shall be made if,
at the time of such payment, there exists (a) a default in the payment of all or
any portion of any Company Senior Indebtedness and the Trustee has received
written notice thereof from the Company, from holders of Company Senior
Indebtedness or from any trustee, representative or agent therefor, or (b) any
other default affecting Company Senior Indebtedness as a result of which the
maturity of Company Senior Indebtedness has been accelerated and the Trustee has
received written notice from the Company, from holders of Company Senior
Indebtedness or from any trustee, representative or agent therefor, and such
default shall not have been cured or waived by or on behalf of the holders of
such Company Senior Indebtedness.

         (3) If, notwithstanding the foregoing provisions prohibiting such
payment or distribution, the Trustee or any Holder shall have received any
payment on account of the principal of or any premium or Interest on or
Additional Amounts with respect to the Securities when such payment is
prohibited by this Section 1702 and before all amounts payable on, under or in
connection with Company Senior Indebtedness are paid in full in cash or cash
equivalents, then and in such event (subject to the provisions of Section 1708)
such payment or distribution shall be

                                       95
<PAGE>

received and held in trust for the holders of Company Senior Indebtedness and,
at the written direction of the trustee, representative or agent for the holders
of the Company Senior Indebtedness, shall be paid to the holders of the Company
Senior Indebtedness remaining unpaid to the extent necessary to pay such Company
Senior Indebtedness in full in cash or cash equivalents.

         Upon any payment or distribution of assets or securities referred to in
this Article Seventeen, the Trustee and the Holders shall be entitled to rely
upon any order or decree of a court of competent jurisdiction in which such
dissolution, winding up, liquidation or reorganization proceedings are pending
or upon a certificate of the receiver, trustee in bankruptcy, liquidating
trustee, agent or other Person making any such payment or distribution,
delivered to the Trustee or to the Holders for the purpose of ascertaining the
Persons entitled to participate in such distribution, the holders of Company
Senior Indebtedness and other Indebtedness of the Company, the amount thereof or
payable thereon, the amount or amounts paid or distributed thereon and all other
facts pertinent thereto or to this Article Seventeen.

                Section 1703. Payments Which May Be Made Prior to Notice.

         Nothing in this Article Seventeen or elsewhere in this Indenture shall
prevent (1) the Company, except under the conditions described in Section 1702,
from making payments of principal of or any premium or Interest on or Additional
Amounts with respect to the Securities or from depositing with the Trustee any
monies for such payments, or (2) the application by the Trustee of any monies
deposited with it for the purpose of making such payments of principal of or any
premium or Interest on or Additional Amounts with respect to the Securities, to
the Holders entitled thereto, unless at least two Business Days prior to the
date when such payment would otherwise (except for the prohibitions contained in
Section 1702) become due and payable, the Trustee shall have received the
written notice provided for in Section 1702(2)(a) or (b).

                Section 1704. Rights of Holders of Senior Indebtedness Not to Be
                              Impaired.

         No right of any present or future holder of any Company Senior
Indebtedness to enforce subordination as herein provided shall at any time or in
any way be prejudiced or impaired by any act or failure to act in good faith by
any such holder, or by any noncompliance by the Company with the terms and
provisions and covenants herein regardless of any knowledge thereof any such
holder may have or otherwise be charged with.

         The provisions of this Article Seventeen are intended to be for the
benefit of, and shall be enforceable directly by, the holders of Company Senior
Indebtedness. Notwithstanding anything to the contrary in this Article
Seventeen, to the extent any Holders or the Trustee have paid over or delivered
to any holder of Company Senior Indebtedness any payment or distribution
received on account of the principal of or any premium or Interest on or
Additional Amounts with respect to the Securities to which any other holder of
Company Senior Indebtedness shall be entitled to share in accordance with
Section 1702, no holder of Company Senior Indebtedness shall have a claim or
right against any Holders or the Trustee with respect to any such payment or
distribution or as a result of the failure to make payments or distributions to
such other holder of Company Senior Indebtedness.

                             Section 1705. Trustee May Take Action to Effectuate
                                           Subordination.

         Each Holder of a Security, by his acceptance thereof, authorizes and
directs the Trustee on his behalf to take such action as may be required by the
trustee, representative or agent for holders of Company Senior Indebtedness or
by the Company to effectuate, as between the holders of Company Senior
Indebtedness and the Holders, the subordination as provided in this Article
Seventeen and appoints the Trustee his attorney-in-fact for any and all such
purposes.

                             Section 1706. Subrogation.

         Upon the payment in full, in cash or cash equivalents, of all Company
Senior Indebtedness, any Holder shall be subrogated to the rights of the holders
of such Company Senior Indebtedness to receive payments or distributions of
assets of the Company in respect of such Company Senior Indebtedness until the
Securities shall be paid in full; and for the purposes of such subrogation, no
payments or distributions to holders of such Company Senior Indebtedness of any
cash property or securities to which such Holders of the Securities would be
entitled except for this Article Seventeen, and no payment pursuant to this
Article Seventeen to holders of such Company Senior Indebtedness by such Holders
of the Securities, shall, as between the Company, its creditors other than
holders of such Company Senior Indebtedness and such Holders of the Securities,
be deemed to be a payment by the Company to or on account of such Company Senior
Indebtedness, it being understood that the provisions of this Article Seventeen
are solely for the purpose of defining the relative rights of the holders of
such Company Senior Indebtedness, on the one hand, and such Holders of the
Securities, on the other hand.

         If any payment or distribution to which Holders of Securities would
otherwise have been entitled but for the provisions of this Article Seventeen
shall have been applied, pursuant to this Article Seventeen, to the payment of
all Company Senior Indebtedness, then and in such case such Holders of the
Securities shall be entitled to receive from the holders of such Company Senior
Indebtedness at the time outstanding any payments or distributions received by
such holders of Company Senior Indebtedness in excess of the amount sufficient
to pay, in cash or cash equivalents, all such Company Senior Indebtedness in
full.

                             Section 1707. Obligations of Company Unconditional;
                                           Reinstatement.

         Nothing in this Article Seventeen or elsewhere in this Indenture or in
any Security is intended to or shall impair, as among the Company, its creditors
other than holders of Company Senior Indebtedness and Holders of the Securities,
the obligations of the Company, which are absolute and unconditional, to pay to
such Holders the principal of and any premium and Interest on and Additional
Amounts with respect to the Securities as and when the same shall become due and
payable in accordance with their terms, or is intended to or shall affect the
relative rights of such Holders of the Securities and creditors of the Company
other than the holders of the Company Senior Indebtedness, nor shall anything
herein or therein prevent the Trustee or any Holder of Securities or holder of
Preferred Securities, as applicable, from exercising all remedies otherwise
permitted by applicable law under this Indenture, subject to the rights, if any,
under this Article Seventeen of the holders of such Company Senior Indebtedness
in respect of cash, property or securities of the Company received upon the
exercise of any such remedy.

                                       97
<PAGE>

         The failure to make a scheduled payment of principal of or any premium
or Interest on or Additional Amounts with respect to the Securities by reason of
Section 1702 shall not be construed as preventing the occurrence of a Default or
an Event of Default under Section 501; provided, however, that if (1) the
conditions preventing the making of such payment no longer exist, and (2) such
Holders of the Securities are made whole with respect to such omitted payments,
the Default or Event of Default relating thereto (including any failure to pay
any accelerated amounts) shall be automatically waived, and the provisions of
the Indenture shall be reinstated as if no such Event of Default had occurred.

             Section 1708. Trustee Entitled to Assume Payments Not Prohibited in
                           Absence of Notice.

         The Trustee or Paying Agent shall not be charged with the knowledge of
the existence of any default in the payment of all or a portion of any Company
Senior Indebtedness or any other default affecting Company Senior Indebtedness
as a result of which the maturity of the Company Senior Indebtedness has been
accelerated, unless and until the Trustee or Paying Agent shall have received
written notice thereof from the Company or one or more holders of Company Senior
Indebtedness or from any trustee, representative or agent therefor; and, prior
to the receipt of any such written notice, the Trustee or Paying Agent may
conclusively assume that no such facts exist.

         Unless at least two Business Days prior to the date when by the terms
of this Indenture any monies are to be deposited by the Company with the Trustee
or any Paying Agent for any purpose (including, without limitation, the payment
of the principal of or any premium or Interest on or Additional Amounts with
respect to any Security), the Trustee or Paying Agent shall have received with
respect to such monies the notice provided for in Section 1702, the Trustee or
Paying Agent shall have full power and authority to receive and apply such
monies to the purpose for which they were received. Neither of them shall be
affected by any notice to the contrary, which may be received by either on or
after such second Business Day. The foregoing shall not apply to the Paying
Agent if the Company is acting as Paying Agent. Nothing in this Section 1708
shall limit the right of the holders of Company Senior Indebtedness to recover
payments as contemplated by Section 1702. The Trustee or Paying Agent shall be
entitled to rely on the delivery to it of a written notice by a Person
representing himself or itself to be a holder of such Company Senior
Indebtedness (or a trustee, representative or agent on behalf of such holder) to
establish that such notice has been given by a holder of such Company Senior
Indebtedness or a trustee, representative or agent on behalf of any such holder.
The Trustee shall not be deemed to have any fiduciary duty to the holders (and
shall be fully protected in relying upon such notice) of Company Senior
Indebtedness.

           Section 1709. Right of Trustee to Hold Senior Indebtedness.

         The Trustee and any Paying Agent shall be entitled to all of the rights
set forth in this Article Seventeen in respect of any Company Senior
Indebtedness at any time held by them, to the same extent as any other holder of
such Company Senior Indebtedness, and nothing in this Indenture shall be
construed to deprive the Trustee or any Paying Agent of any of its rights as
such holder.

                        Section 1710. Notice to Trustee.

         The Company shall give prompt written notice to the Trustee or Paying
Agent of any fact known to the Company which would prohibit the making of any
payment to or by the Trustee in respect of the Securities. Failure to give such
notice shall not affect the subordination of the Securities to Company Senior
Indebtedness. Notwithstanding the provisions of this or any other provision of
this Indenture, the Trustee or Paying Agent shall not be charged with knowledge
of the existence of any facts which would prohibit the making of any payment to
or by the Trustee or Paying Agent in respect of the Securities pursuant to this
Article Seventeen, unless and until the Trustee or Paying Agent shall have
received written notice from the Company or a holder of Company Senior
Indebtedness or from any trustee or agent therefor; and, prior to the receipt of
any such written notice, the Trustee, subject to the provisions of Section 601,
or Paying Agent shall be entitled in all respects to assume that no such facts
exist; provided, however, that if a Responsible Officer of the Trustee or Paying
Agent shall not have received, at least three Business Days prior to the date
upon which by the terms hereof any such money may become payable for any purpose
(including, without limitation, the payment of the principal of or any premium
or Interest on or Additional Amounts with respect to any Security, the notice
with respect to such money provided for in this Section 1710, then, anything
herein contained to the contrary notwithstanding, the Trustee or Paying Agent
shall have full power and authority to receive such money and to apply the same
to the purpose for which such money was received and shall not be affected by
any notice to the contrary which may be received by it within three Business
Days prior to such date.

         The Trustee, subject to the provisions of Section 601, or Paying Agent
shall be entitled to conclusively rely on the delivery to it of a written notice
by a Person representing himself or itself to be a holder of Company Senior
Indebtedness (or a trustee or agent on behalf of such holder) to establish that
such notice has been given by a holder of Company Senior Indebtedness (or a
trustee or agent on behalf of any such holder). In the event that the Trustee or
Paying Agent determines in good faith that further evidence is required with
respect to the right of any Person as a holder of Company Senior Indebtedness to
participate in any payment or distribution pursuant to this Article Seventeen,
the Trustee or Paying Agent may request such Person to furnish evidence to the
reasonable satisfaction of the Trustee or Paying Agent as to the amount of
Company Senior Indebtedness held by such Person, the extent to which such Person
is entitled to participate in such payment or distribution and any other facts
pertinent to the rights of such Person under this Article Seventeen, and if such
evidence is not furnished, the Trustee or Paying Agent may defer any payment
which it may be required to make for the benefit of such Person pursuant to the
terms of this Indenture pending judicial determination as to the rights of such
Person to receive such payment.

                      Section 1711. Reliance on Judicial Order or Certificate of
                                    Liquidating Agent.

         Upon any payment or distribution of assets of the Company referred to
in this Article Seventeen, the Trustee, subject to the provisions of Section
601, and the Holders of the Securities shall be entitled to rely upon any order
or decree entered by any court of competent jurisdiction in which such
insolvency, bankruptcy, receivership, liquidation, reorganization, dissolution,
winding up or similar case or proceeding is pending, or a certificate of the
trustee in bankruptcy, liquidating trustee, Custodian, receiver, assignee for
the benefit of creditors, agent or

other Person making such payment or distribution, delivered to the Trustee or to
the Holders of Securities, for the purpose of ascertaining the Persons entitled
to participate in such payment or distribution, the holders of Company Senior

               Section 1712. Trustee Not Fiduciary for Holders of Company Senior

         The Trustee shall not be deemed to owe any fiduciary duty to the
holders of Company Senior Indebtedness and shall not be liable to any such
holders if the Trustee shall in good faith mistakenly pay over or distribute to
Holders of Securities or to the Company or to any other Person cash, property or
securities to which any holders of Company Senior Indebtedness shall be entitled
by virtue of this Article or otherwise. With respect to the holders of Company
Senior Indebtedness, the Trustee undertakes to perform or to observe only such
of its covenants or obligations as are specifically set forth in this Article
and no implied covenants or obligations with respect to holders of Company
Senior Indebtedness shall be read into this Indenture against the Trustee.

Trustee under or pursuant to Section 606.

                                ARTICLE EIGHTEEN

                           SUBORDINATION OF GUARANTEE

               Section 1801. Guarantee Subordinated to Guarantor Senior
                             Indebtedness

         Notwithstanding the provisions of Section 506 or any other provision
herein or in any Security, the Guarantor and the Trustee and, by their
acceptance thereof, the Holders of the Securities (a) covenant and agree that
all payments by the Guarantor pursuant to the Guarantee of the principal of and
any premium or Interest on and any Additional Amounts with respect to the
Securities (other than Securities which have been discharged pursuant to Article
Four or Securities that provide for a sinking fund pursuant to the Board
Resolution, Officers' Certificate or supplemental indenture establishing the
series as to which such sinking fund is applicable) shall be subordinated in
accordance with the provisions of this Article Eighteen in right of payment to
the prior payment in full, in cash or cash equivalents, of all amounts payable
on, under or in connection with Guarantor Senior Indebtedness, and (b)
acknowledge that holders of Guarantor Senior Indebtedness are or shall be
relying on this Article Eighteen. Nothing herein or in any Security is intended
to or shall limit the amount of Guarantor Indebtedness the Guarantor may incur.

               Section 1802. Priority and Payment of Proceeds in Certain Events:
                             Remedies Standstill

property or securities, upon any dissolution

                                      100
<PAGE>

or winding up or total or partial liquidation or reorganization of the
Guarantor, whether voluntary or involuntary, or in bankruptcy, insolvency,
receivership or other proceedings, all amounts payable on, under or in
connection with Guarantor Senior Indebtedness (including any Interest accruing
on such Guarantor Senior Indebtedness subsequent to the commencement of a
bankruptcy, insolvency, receivership or similar proceeding) shall first be paid,
ratably according to the aggregate amounts remaining unpaid on account of the
principal of any premium and Interest on the Guarantor Senior Indebtedness held
or represented by each, to the extent necessary to make payment in full of all
Guarantor Senior Indebtedness remaining unpaid, in cash, or payment provided for
in cash or cash equivalents, ratably according to the aggregate amounts
remaining unpaid on account of the principal of and any premium and Interest on
the Guarantor Senior Indebtedness held or represented by each, to the extent
necessary to make payment in full of all Guarantor Senior Indebtedness remaining
unpaid, before the Holders or the Trustee on behalf of the Holders or the
holders of Preferred Securities, if any, shall be entitled to receive from the
Guarantor pursuant to the Guarantee any payment of principal of or any premium
or Interest on or Additional Amounts with respect to the Securities or
distribution of any assets or securities.

         (2) No direct or indirect payment by or on behalf of the Guarantor
pursuant to the Guarantee of principal of or any premium or Interest on or
Additional Amounts with respect to the Securities (other than Securities which
have been discharged pursuant to Article Four or Securities that provide for a
sinking fund), whether pursuant to the terms of this Securities or upon
acceleration or otherwise, shall be made if, at the time of such payment, there
exists (a) a default in the payment of all or any portion of any Guarantor
Senior Indebtedness and the Trustee has received written notice thereof from the
Guarantor, from holders of Guarantor Senior Indebtedness or from any trustee,
representative or agent therefor, or (b) any other default affecting Guarantor
Senior Indebtedness as a result of which the maturity of Guarantor Senior
Indebtedness has been accelerated and the Trustee has received written notice
from the Guarantor, from holders of Guarantor Senior Indebtedness or form any
trustee, representative or agent therefor, and such default shall not have been
cured or waived by or on behalf of the holders of such Guarantor Senior
Indebtedness.

         (3) If, notwithstanding the foregoing provisions prohibiting such
payment or distribution, the Trustee or any Holder shall have received any
payment pursuant to the Guarantee on account of the principal or any premium or
Interest on or Additional Amounts with respect to the Securities when such
payment is prohibited by this Section 1802 and before all amounts payable on,
under or in connection with Guarantor Senior Indebtedness are paid in full in
cash or cash equivalents, then and in such event (subject to the provisions of
Section 1808) such payment or distribution shall be received and held in trust
for the holders of Guarantor Senior Indebtedness and, at the written direction
of the trustee, representative or agent for the holders of the Guarantor Senior
Indebtedness, shall be paid to the holders of the Guarantor Senior Indebtedness
remaining unpaid to the extent necessary to pay such Guarantor Senior
Indebtedness in full in cash or cash equivalents.

         Upon any payment or distribution of assets or securities referred to in
this Article Eighteen, the Trustee and the Holders shall be entitled to rely
upon any order or decree of a court of competent jurisdiction in which such
dissolution, winding up, liquidation or reorganization proceedings are pending
or upon a certificate of the receiver, trustee in bankruptcy, liquidating
trustee, agent or other Person making any such payment or distribution,
delivered to the Trustee or

                                      101
<PAGE>

to the Holders for the purpose of ascertaining the Persons entitled to
participate in such distribution, the holders of Guarantor Senior Indebtedness
and other Indebtedness of the Guarantor, the amount thereof or payable thereon,
the amount or amounts paid or distributed thereon and all other facts pertinent
thereto or to this Article Eighteen.

            Section 1803. Payments which May Be Made Prior to Notice

         Nothing in the Article Eighteen or elsewhere in this Indenture shall
prevent (1) the Guarantor, except under the conditions described in Section
1802, from making payments of principal of or any premium or Interest on or
Additional Amounts pursuant to the Guarantee with respect to the Securities or
from depositing with the Trustee any monies for such payments, or (2) the
application by the Trustee of any monies deposited with it for the purpose of
making such payments of principal of or any premium or Interest on or Additional
Amounts with respect to the Securities, to the Holders entitled thereto, unless
at least two Business Days prior to the date when such payment would otherwise
(except for the prohibitions contained in Section 1802) become due and payable,
the Trustee shall have received the written notice provided for in Section
1802(2)(a) or (b).

            Section 1804. Rights of Holders of Guarantor Senior Indebtedness Not
                          to Be Impaired

         No right of any present or future holder of any Guarantor Senior
Indebtedness to enforce subordination as herein provided shall at any time or in
any way be prejudiced or impaired by any act or failure to act in good faith by
any such holder, or by any noncompliance by the Guarantor with the terms and
provisions and covenants herein regardless of any knowledge thereof any such
holder may have or otherwise be charged with.

         The provisions of this Article Eighteen are intended to be for the
benefit of, and shall be enforceable directly by, the holders of Guarantor
Senior Indebtedness. Notwithstanding anything to the contrary in this Article
Eighteen, to the extent any Holders or the Trustee have paid over or delivered
to any holder of Guarantor Senior Indebtedness any payment or distribution
received on account of the principal of or any premium or Interest on or
Additional Amounts with respect to the Securities to which any other holder of
Guarantor Senior Indebtedness shall be entitled to share in accordance with
Section 1802, no holder of Guarantor Senior Indebtedness shall have a claim or
right against any Holders or the Trustee with respect to any such payment or
distribution or as a result of the failure to make payments or distributions to
such other holder of Guarantor Senior Indebtedness.

            Section 1805. Trustee May Take Action to Effectuate Subordination.

         Each Holder of a Security, by his acceptance thereof, authorized and
directs the Trustee on his behalf to take such action as may be required by the
trustee, representative or agent for holders of Guarantor Senior Indebtedness or
by the Guarantor to effectuate, as between the holders of Guarantor Senior
Indebtedness and the Holders, the subordination as provided in this Article
Eighteen and appoints the Trustee his attorney-in-fact for any and all such
purposes.

                           Section 1806. Subrogation.

         Upon the payment in full, in cash or cash equivalents, of all Guarantor
Senior Indebtedness, any Holder shall be subrogated to the rights of the holders
of such Guarantor Senior Indebtedness to receive payments or distributions of
assets of the Guarantor in respect of such Guarantor Senior Indebtedness until
the Securities shall be paid in full; and for the purposes of such subrogation,
no payments or distributions to holders of such Guarantor Senior Indebtedness of
any cash property or securities to which such Holders of the Securities would be
entitled except for this Article Eighteen, and not payment pursuant to this
Article Eighteen to the holders of such Guarantor Senior Indebtedness by such
Holders of the Securities, shall, as between the Guarantor, its creditors other
than holders of such Guarantor Senior Indebtedness and such Holders of the
Securities, be deemed to be a payment by the Guarantor to or on account of such
Guarantor Senior Indebtedness, it being understood that the provisions of this
Article Eighteen are solely for the purpose of defining the relative rights of
the holders of such Guarantor Senior Indebtedness, on the one hand, and such
Holders of the Securities, on the other hand.

         If any payment or distribution to this Holders of Securities would
otherwise have been entitled but for the provisions of this Article Eighteen
shall have been applied, pursuant to this Article Eighteen, to the payment of
all Guarantor Senior Indebtedness, then and in such case such Holders of the
Securities shall be entitled to receive from the holders of such Guarantor
Senior Indebtedness at the time outstanding any payments or distributions
received by such holders of Guarantor Senior Indebtedness in excess of the
amount sufficient to pay, in cash or cash equivalents, all such Guarantor Senior
Indebtedness in full.

                           Section 1807. Obligations of Guarantor Unconditional;
                                         Reinstatement.

         Nothing in this Article Eighteen or elsewhere in this Indenture or in
any Security is intended to or shall impair as among the Guarantor, its
creditors other than holders of Guarantor Senior Indebtedness of the Securities,
the obligations of the Guarantor, which are absolute and unconditional, to pay
to such Holders pursuant to the Guarantee the principal of and any premium and
Interest on and Additional Amounts with respect to the Securities as and when
the same shall become due and payable in accordance with their terms, or is
intended to or shall affect the relative rights of such Holders of the
Securities and creditors of the Guarantor other than the holders of the
Guarantor Senior Indebtedness, nor shall anything herein or therein prevent the
Trustee or any Holder of Securities or holder of Preferred Securities, as
applicable, from exercising all remedies otherwise permitted by applicable law
under this Indenture, subject to the rights, if any, under this Article Eighteen
of the holders of such Guarantor Senior Indebtedness in respect of cash,
property or securities of the Guarantor received upon the exercise of any such
remedy.

         The failure to make a scheduled payment pursuant to the Guarantee of
principal of or any premium or Interest on or Additional Amounts with respect to
the Securities by reason of Section 1802 shall not be construed as preventing
the occurrence of a Default or an Event of Default under Section 501; provided,
however, that if (1) the conditions preventing the making of such payment no
longer exist, and (2) such Holders of the Securities are made whole with respect
to such omitted payments, the Default or Event of Default relating thereto
(including any failure to pay

                                      103
<PAGE>

any accelerated amounts) shall be automatically waived, and the provisions of
the Indenture shall be reinstated as if no such Event of Default had occurred.

                        Section 1808. Trustee Entitled to Assume Payments Not
                                      Prohibited in Absence of Notice.

         The Trustee or Paying Agent shall not be charged with the knowledge of
the existence of any default in the payment of all or a portion of Guarantor
Senior Indebtedness or any other default affecting Guarantor Senior Indebtedness
as a result of which the maturity of the Guarantor Senior Indebtedness has been
accelerated, unless and until the Trustee or Paying Agent shall have received
written notice thereof from the Guarantor or one or more holders of Guarantor
Senior Indebtedness or from any trustee, representative or agent therefor; and,
prior to the receipt of any such written notice, the Trustee or Paying Agent may
conclusively assume that no such facts exist.

         Unless at least two Business Days prior to the date when by the terms
of this Indenture any monies are to be deposited by the Guarantor with the
Trustee or any Paying Agent for any purpose (including, without limitation, the
payment pursuant to the Guarantee of the principal of or any premium or Interest
on or Additional Amounts with respect to any Security), the Trustee or Paying
Agent shall have received with respect to such monies the notice provided for in
Section 1802, the Trustee or Paying Agent shall have full power and authority to
receive and apply such monies to the purpose for which they were received.
Neither of them shall be affected by any notice to the contrary, which may be
received by either on or after such second Business Day. The foregoing shall not
apply to the Paying Agent if the Guarantor is acting as Paying Agent. Nothing in
this Section 1808 shall limit the right of the holders of Guarantor Senior
Indebtedness to recover payments as contemplated by Section 1802. The Trustee or
Paying Agent shall be entitled to rely on the delivery to it of a written notice
by a Person representing himself or itself to be a holder of such Guarantor
Senior Indebtedness (or a trustee, representative or agent on behalf of such
holder) to establish that such notice has been given by a holder of such
Guarantor Senior Indebtedness or a trustee, representative or agent on behalf of
any such holder. The Trustee shall not be deemed to have any fiduciary duty to
the holders (and shall be fully protected in relying upon such notice) of
Guarantor Senior Indebtedness.

                        Section 1809. Right of Trustee to Hold Guarantor Senior
                                      Indebtedness.

         The Trustee and any Paying Agent shall be entitled to all of the rights
set forth in this Article Eighteen in respect of any Guarantor Senior
Indebtedness at any time held by them, to the same extent as any other holder of
such Guarantor Senior Indebtedness, and nothing in this Indenture shall be
construed to deprive the Trustee or any Paying Agent of any of its rights as
such holder.

                        Section 1810. Notice to Trustee.

         The Guarantor shall give prompt written notice to the Trustee or Paying
Agent of any fact known to the Guarantor which would prohibit the making of any
payment to or by the Trustee in respect of the Securities. Failure to give such
notice shall not affect the subordination of the Guarantee to Guarantor Senior
Indebtedness. Notwithstanding the provisions of this or any other

                                      104
<PAGE>

provision of this Indenture, the Trustee or Paying Agent shall not be charged
with knowledge of the existence of any facts which would prohibit the making of
any payment to or by the Trustee or Paying Agent in respect to the Securities
pursuant to this Article Eighteen, unless and until the Trustee or Paying Agent
shall have received written notice from the Guarantor or a holder of Guarantor
Senior Indebtedness or from any trustee or agent therefor; and prior to the
receipt of any such written notice, the Trustee, subject to the provisions of
Section 601, or Paying Agent shall be entitled in all respect to assume that no
such facts exist; provided, however, that if a Responsible Officer of the
Trustee or Paying Agent shall not have received, at least three Business Days
prior to the date upon which by the terms hereof any such money may become
payable for any purpose (including, without limitation, the payment pursuant to
the Guarantee of the principal of or any premium or Interest on or Additional
Amounts with respect to any Security, the notice with respect to such money
provided for in this Section 1810, then, anything herein contained to the
contrary notwithstanding, the Trustee or Paying Agent shall have full power and
authority to receive such money and to apply the same to the purpose for which
such money was received and shall not be affected by any notice to the contrary
which may be received by it within three Business Days prior to such date.

         The Trustee, subject to the provisions of Section 601, or Paying Agent
shall be entitled to conclusively rely on the delivery to it of a written notice
by a Person representing himself or itself to be a holder of Guarantor Senior
Indebtedness (or a trustee or agent on behalf of such holder) to establish that
such notice has been given by a holder of Guarantor Senior Indebtedness (or a
trustee or agent on behalf of any such holder). In the event that the Trustee or
Paying Agent determines in good faith that further evidence is required with
respect to the right of any Person as a holder of Guarantor Senior Indebtedness
to participate in any payment or distribution pursuant to this Article Eighteen,
the Trustee or Paying Agent may request such Person to furnish evidence to the
reasonable satisfaction of the Trustee or Paying Agent as to the amount of
Guarantor Senior Indebtedness held by such Person, the extent to which such
Person is entitled to participate in such payment or distribution and any other
facts pertinent to the rights of such Person under this Article Eighteen, and if
such evidence is not furnished, the Trustee or paying Agent may defer any
payment which it may be required to make for the benefit of such Person pursuant
to the terms of this Indenture pending judicial determination as to the rights
of such Person to receive such payment.

                      Section 1811. Reliance on Judicial Order or Certificate of
                                    Liquidating Agent.

         Upon any payment or distribution of assets of the Guarantor referred to
in this Article Eighteen, the Trustee subject to the provisions of Section 601,
and the Holders of the Securities shall be entitled to rely upon any order or
decree entered by any court of competent jurisdiction in which such insolvency,
bankruptcy, receivership, liquidation, reorganization, dissolution, winding up
or similar case or proceeding is pending, or a certificate of the trustee in
bankruptcy, liquidating trustee, Custodian, receiver, assignee for the benefit
of creditors, agent or other Person making such payment or distribution,
delivered to the Trustee or to the Holders of Securities, for the purpose of
ascertaining the Persons entitled to participate in such payment or
distribution, the holders of Guarantor Senior Indebtedness and other
indebtedness of the Guarantor, the amount thereof or payable thereon, the amount
or amounts paid or distributed thereon and all other facts pertinent thereto or
to this Article Eighteen.

                                      Guarantor Senior Indebtedness.

         The Trustee shall not be deemed to owe any fiduciary duty to the
holders of Guarantor Senior Indebtedness and shall not be liable to any such
holders if the Trustee shall in good faith mistakenly pay over or distribute to
Holders of Securities or to the Guarantor or to any other Person cash, property
or securities to which any holders of Guarantor Senior Indebtedness shall be
entitled by virtue of this Article or otherwise. With respect to the holders of
Guarantor Senior Indebtedness, the Trustee undertakes to perform or to observe
only such of its covenants or obligations as are specifically set forth in this
Article and no implied covenants or obligations with respect to holders of
Guarantor Senior Indebtedness shall be read into this Indenture against the
Trustee.
