provision of this Indenture relating to such particular application or request,

            Every certificate or opinion with respect to compliance with a

such Person may certify or give an opinion with respect to some matters and one
or more other such Persons as to other matters, and any such Person may certify
or give an opinion as to such matters in one or several documents.

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

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

Section 104. Acts of Holders; Record Dates.

            (a) Any request, demand, authorization, direction, notice, consent,
waiver or other action provided by this Indenture to be given or taken by
Holders may be embodied in and evidenced by one or more instruments of
substantially similar tenor signed by such Holders in person or by agent duly
appointed in writing; and, except as herein otherwise expressly provided, such
action shall become effective when such instrument or instruments are delivered
to the Trustee and, where it is hereby expressly required, to the Company or the
Guarantor or both of them. Such instrument or instruments (and the action
embodied therein and evidenced thereby) are herein sometimes referred to as the
"ACT" of the Holders signing such instrument or instruments. Proof of execution
of any such instrument or of a writing appointing any such agent shall be
sufficient for any purpose of this Indenture and (subject to Section 601)
conclusive in favor of the Trustee and the Company or the Guarantor, if made in
the manner provided in this Section.

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

                                      -7-
<PAGE>

that the individual signing such instrument or writing acknowledged to him the
execution thereof. Where such execution is by a signer acting in a capacity
other than his individual capacity, such certificate or affidavit shall also
constitute sufficient proof of his authority. The fact and date of the execution
of any such instrument or writing, or the authority of the Person executing the
same, may also be proved in any other manner which the Trustee deems sufficient.

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

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

            (e) The Company may set any day as a record date for the purpose of
determining the Holders of Outstanding Securities of any series entitled to
give, make or take any request, demand, authorization, direction, notice,
consent, waiver or other action provided or permitted by this Indenture to be
given, made or taken by Holders of Securities of such series, provided that the
Company may not set a record date for, and the provisions of this paragraph
shall not apply with respect to, the giving or making of any notice,
declaration, request or direction referred to in the next paragraph. If any
record date is set pursuant to this paragraph, the Holders of Outstanding
Securities of the relevant series on such record date, and no other Holders,
shall be entitled to take the relevant action, whether or not such Holders
remain Holders after such record date; provided that no such action shall be
effective hereunder unless taken on or prior to the applicable Expiration Date
by Holders of the requisite principal amount of Outstanding Securities of such
series on such record date. Nothing in this paragraph shall be construed to
prevent the Company from setting a new record date for any action for which a
record date has previously been set pursuant to this paragraph (whereupon the
record date previously set shall automatically and with no action by any Person
be cancelled and of no effect), and nothing in this paragraph shall be construed
to render ineffective any action taken by Holders of the requisite principal
amount of Outstanding Securities of the relevant series on the date such action
is taken. Promptly after any record date is set pursuant to this paragraph, the
Company, at its own expense, shall cause notice of such record date, the
proposed action by Holders and the applicable Expiration Date to be given to the
Trustee in writing and to each Holder of Securities of the relevant series in
the manner set forth in Section 106.

            The Trustee may set any day as a record date for the purpose of
determining the Holders of Outstanding Securities of any series entitled to join
in the giving or making of (i) any Notice of Default, (ii) any declaration of
acceleration referred to in Section 502, (iii) any request to institute
proceedings referred to in Section 507(2) or (iv) any direction referred to in
Section 512, in each case with respect to Securities of such series. If any
record date is set pursuant to this paragraph, the Holders of Outstanding
Securities of such series on such record date, and no other Holders, shall be
entitled to join in such notice, declaration, request or direction, whether or
not such Holders remain Holders after such record date; provided that no such
action shall be effective hereunder unless taken on or prior to the applicable
Expiration Date by Holders of the requisite principal amount of Outstanding
Securities of such series on such record date. Nothing in this paragraph shall
be construed to prevent the Trustee from setting a new record date for any
action for which a record date has previously been set pursuant to this
paragraph (whereupon the record date previously set shall automatically and with
no action by any Person be cancelled and

                                      -8-
<PAGE>

of no effect), and nothing in this paragraph shall be construed to render
ineffective any action taken by Holders of the requisite principal amount of
Outstanding Securities of the relevant series on the date such action is taken.
Promptly after any record date is set pursuant to this paragraph, the Trustee,
at the Company's expense, shall cause notice of such record date, the proposed
action by Holders and the applicable Expiration Date to be given to the Company
in writing and to each Holder of Securities of the relevant series in the manner
set forth in Section 106.

            With respect to any record date set pursuant to this Section, the
party hereto which sets such record dates may designate any day as the
"Expiration Date" and from time to time may change the Expiration Date to any
earlier or later day; provided that no such change shall be effective unless
notice of the proposed new Expiration Date is given to the other party hereto in
writing, and to each Holder of Securities of the relevant series in the manner
set forth in Section 106, on or prior to the existing Expiration Date. If an
Expiration Date is not designated with respect to any record date set pursuant
to this Section, the party hereto which set such record date shall be deemed to
have initially designated the 180th day after such record date as the Expiration
Date with respect thereto, subject to its right to change the Expiration Date as
provided in this paragraph. Notwithstanding the foregoing, no Expiration Date
shall be later than the 180th day after the applicable record date.

            Without limiting the foregoing, a Holder entitled hereunder to take
any action hereunder with regard to any particular Security may do so with
regard to all or any part of the principal amount of such Security or by one or
more duly appointed agents each of which may do so pursuant to such appointment
with regard to all or any part of such principal amount.

Section 105. Notices, Etc., to Trustee, Company and Guarantor.

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

            (1) the Trustee by any Holder or by the Company or the Guarantor
      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

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

Section 106. Notice to Holders; Waiver.

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

                                      -9-
<PAGE>

the Security Register, not later than the latest date, and not earlier than the
earliest date, prescribed for the giving of such notice. In any case where
notice to Holders is given by mail, neither the failure to mail such notice, nor
any defect in any notice so mailed, to any particular Holder shall affect the
sufficiency of such notice with respect to other Holders. Where this Indenture
provides for notice in any manner, such notice may be waived in writing by the
Person entitled to receive such notice, either before or after the event, and
such waiver shall be the equivalent of such notice. Waivers of notice by Holders
shall be filed with the Trustee, but such filing shall not be a condition
precedent to the validity of any action taken in reliance upon such waiver.

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

Section 107. Conflict with Trust Indenture Act.

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

Section 108. Effect of Headings and Table of Contents.

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

Section 109. Successors and Assigns.

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

Section 110. Separability Clause.

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

Section 111. Benefits of Indenture.

            Nothing in this Indenture or in the Securities, express or implied,
shall give to any Person, other than the parties hereto and their successors
hereunder and the Holders, any benefit or any legal or equitable right, remedy
or claim under this Indenture.

      the regulations thereunder) including the rate or rates at which such

            (20) any addition to or change in the Events of Default which apply

<PAGE>

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

            All Securities of any one series shall be substantially identical
except as to denomination and except as may otherwise be provided in or pursuant
to the Board Resolution referred to above and (subject to Section 303) set forth
in the Officers' Certificate or in any such indenture supplemental hereto.

            If any of the terms of the series are established by action taken
pursuant to a Board Resolution, a copy of an appropriate record of such action
shall be certified by the Secretary or an Assistant Secretary of the Company and
the Guarantor and delivered to the Trustee at or prior to the delivery of the
Officers' Certificate setting forth the terms of the series. Such Board
Resolution may provide general terms or parameters for Securities of such series
and may provide that the specific terms of particular Securities of such series,
and the Persons authorized to determine such terms or parameters, may be
determined in accordance with or pursuant to the Company Order for
authentication and delivery of such Securities.

Section 302. Denominations.

            The Securities of each series shall be issuable in registered form
without coupons in such denominations as shall be specified as contemplated by
Section 301. In the absence of any such provisions with respect to the
Securities of any series, the Securities of such series shall be issuable in
denominations of $1,000 and any integral multiple thereof.

Section 303. Execution, Authentication, Delivery and Dating.

            The Securities shall be executed on behalf of the Company by its
Chairman of the Board, its Chief Executive Officer, its President or one of its
Vice Presidents. The signature of any of these officers on the Securities may be
manual or facsimile.

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

            At any time and from time to time after the execution and delivery
of this Indenture, the Company may deliver Securities of any series executed by
the Company to the Trustee for authentication, together with a Company Order for
the authentication and delivery of such Securities, and the Trustee in
accordance with the Company Order shall authenticate and deliver such
Securities. If the form or terms of the Securities of the series have been
established in or pursuant to one or more Board Resolutions as permitted by
Sections 201 and 301, in authenticating such Securities, and accepting the
additional responsibilities under this Indenture in relation to such Securities,
the Trustee shall be entitled to receive, and (subject to Section 601) shall be
fully protected in relying upon, an Opinion of Counsel stating,

            (a) if the form of such Securities has been established by or
      pursuant to Board Resolution as permitted by Section 201, that such form
      has been established in conformity with the provisions of this Indenture;

                                      -23-
<PAGE>

            (b) if the terms of such Securities have been established by or
      pursuant to Board Resolution as permitted by Section 301, that such terms
      have been established in conformity with the provisions of this Indenture;
      and

            (c) that such Securities, when 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 valid and
      legally binding obligations of the Company, enforceable in accordance with
      their terms, subject to bankruptcy, insolvency, fraudulent transfer,
      reorganization, moratorium and similar laws of general applicability
      relating to or affecting the enforcement of creditors' rights and to
      general equity principles.

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

            Notwithstanding the provisions of Section 301 and of the preceding
paragraph, if all Securities of a series are not to be originally issued at one
time, it shall not be necessary to deliver the Officers' Certificate otherwise
required pursuant to Section 301 or the Company Order and Opinion of Counsel
otherwise required pursuant to such preceding paragraph at or prior to the time
of authentication of each Security of such series if such documents are
delivered at or prior to the time of authentication upon original issuance of
the first Security of such series to be issued.

            Each Security shall be dated the date of its authentication.

            Neither any Security nor the Guarantee endorsed thereon, shall be
entitled to any benefit under this Indenture or be valid or obligatory for any
purpose unless there appears on such Security a certificate of authentication
substantially in the form provided for herein executed by the Trustee by manual
signature, and such certificate upon any Security shall be conclusive evidence,
and the only evidence, that such Security has been duly authenticated and
delivered hereunder and is entitled to the benefits of this Indenture.
Notwithstanding the foregoing, if any Security shall have been authenticated and
delivered hereunder but never issued and sold by the Company, and the Company
shall deliver such Security to the Trustee for cancellation as provided in
Section 309 together with a written statement (which need not comply with
Section 102 and need not be accompanied by an Opinion of Counsel) stating that
such Security has never been issued and sold by the Company, for all purposes of
this Indenture such Security shall be deemed never to have been authenticated
and delivered hereunder and shall never be entitled to the benefits of this
Indenture.

            Reference is made to Section 1302 concerning the execution and
delivery of the Guarantees.

Section 304. Temporary Securities.

            Pending the preparation of definitive Securities of any series, the
Company may execute, and upon Company Order the Trustee shall authenticate and
deliver, temporary Securities which are printed, lithographed, typewritten,
mimeographed or otherwise produced, in any authorized denomination,
substantially of the tenor of the definitive Securities in lieu of

                                      -24-
<PAGE>

which they are issued and having endorsed thereon Guarantees executed by 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 and such Guarantees may determine, as
evidenced by their execution of such Securities and such Guarantees.

            If temporary Securities of any series are issued, the Company will
cause definitive Securities of that series to be prepared without unreasonable
delay. After the preparation of definitive Securities of such series, the
temporary Securities of such series shall be exchangeable for definitive
Securities of such series upon surrender of the temporary Securities of such
series at the office or agency of the Company in a Place of Payment for that
series, without charge to the Holder. Upon surrender for cancellation of any one
or more temporary Securities of any series the Company shall execute and the
Trustee shall authenticate and deliver in exchange therefor a like principal
amount of definitive Securities of the same series and of a like tenor of
authorized denominations. Until so exchanged the temporary Securities of any
series shall in all respects be entitled to the same benefits under this
Indenture as definitive Securities of such series.

Section 305. Registration, Registration of Transfer and Exchange.

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

            Upon surrender for registration of transfer of any Security of any
series at the office or agency in a Place of Payment for that series, the
Company shall execute, and the Trustee shall authenticate and deliver, in the
name of the designated transferee or transferees, one or more new Securities of
the same series, of any authorized denominations and of a like aggregate
principal amount and tenor having endorsed thereon a Guarantee or Guarantees
executed by the Guarantor.

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

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

            Every Security presented or surrendered for registration of transfer
or for exchange shall (if so required by the Company or the Trustee) be duly
endorsed, or be

                                      -25-
<PAGE>

accompanied by a written instrument of transfer in form satisfactory to the
Company and the Security Registrar duly executed, by the Holder thereof or his
attorney duly authorized in writing.

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

            The Company shall not be required (i) to issue, register the
transfer of or exchange Securities of any series during a period beginning at
the opening of business 15 days before the day of the mailing of a notice of
redemption of Securities of that series selected for redemption under Section
1104 and ending at the close of business on the day of such mailing, or (ii) to
register the transfer of or exchange any Security so selected for redemption in
whole or in part, except the unredeemed portion of any Security being redeemed
in part.

            Notwithstanding the foregoing, no Global Security shall be
registered for transfer or exchange, or authenticated or delivered, pursuant to
this Section 305 or Section 304, 306, 906 or 1107 in the name of a Person other
than the Depository for such Security or its nominee until (i) the Depository
with respect to a Global Security notifies the Company that it is unwilling or
unable to continue as Depository for such Global Security or the Depository
ceases to be a clearing agency registered under the Exchange Act, (ii) the
Company executes and delivers to the Trustee a Company Order that such Global
Security shall be so transferable and exchangeable or (iii) there shall have
occurred and be continuing an Event of Default with respect to the Securities of
such series. Upon the occurrence in respect of any Global Security of any series
of any one or more of the conditions specified in clauses (i), (ii) or (iii) of
the preceding sentence or such other conditions as may be specified as
contemplated by Section 301 for such series, such Global Security may be
registered for transfer or exchange for Securities registered in the names of,
or authenticated and delivered to, such Persons as the Depository with respect
to such series shall direct.

            Except as provided in the preceding paragraph, any Security
authenticated and delivered upon registration of transfer of, or in exchange
for, or in lieu of, any Global Security, whether pursuant to this Section,
Section 304, 306, 906 or 1107 or otherwise, shall also be a Global Security and
bear the legend specified in Section 205.

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

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

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

                                      -26-
<PAGE>

Security, a new Security of the same series and of like tenor and principal
amount having endorsed thereon a Guarantee executed by the Guarantor and bearing
a number not contemporaneously outstanding.

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

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

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

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

Section 307. Payment of Interest; Interest Rights Preserved.

            Unless otherwise provided as contemplated by Section 301 with
respect to any series of Securities, interest on any Security which is payable,
and is punctually paid or duly provided for, on any Interest Payment Date shall
be paid to the Person in whose name that Security (or one or more Predecessor
Securities) is registered at the close of business on the Regular Record Date
for such interest.

            Any interest on any Security of any series which is payable, but is
not punctually paid or duly provided for, on any Interest Payment Date (herein
called "Defaulted Interest") shall forthwith cease to be payable to the Holder
on the relevant Regular Record Date by virtue of having been such Holder, and
such Defaulted Interest may be paid by the Company, at its election in each
case, as provided in Clause (1) or (2) below:

            (1) The Company may elect to make payment of any Defaulted Interest
      to the Persons in whose names the Securities of such series (or their
      respective Predecessor Securities) are registered at the close of business
      on a Special Record Date for the payment of such Defaulted Interest, which
      shall be fixed in the following manner. The Company shall notify the
      Trustee in writing of the amount of Defaulted Interest proposed to be paid
      on each Security of such series and the date of the proposed payment, and
      at the same time the Company shall deposit with the Trustee an amount of
      money equal to the aggregate amount proposed to be paid in respect of such
      Defaulted Interest or shall make arrangements satisfactory to the Trustee
      for such deposit prior to the date of the proposed payment, such money
      when deposited to be held in trust for the

                                      -27-
<PAGE>

      benefit of the Persons entitled to such Defaulted Interest as in this
      Clause provided. Thereupon the Trustee shall fix a Special Record Date for
      the payment of such Defaulted Interest which shall be not more than 15
      days and not less than 10 days prior to the date of the proposed payment
      and not less than 10 days after the receipt by the Trustee of the notice
      of the proposed payment. The Trustee shall promptly notify the Company of
      such Special Record Date and, in the name and at the expense of the
      Company, shall cause notice of the proposed payment of such Defaulted
      Interest and the Special Record Date therefor to be mailed, first-class
      postage prepaid, to each Holder of Securities of such series at his
      address as it appears in the Security Register, not less than 10 days
      prior to such Special Record Date. Notice of the proposed payment of such
      Defaulted Interest and the Special Record Date therefor having been so
      mailed, such Defaulted Interest shall be paid to the Persons in whose
      names the Securities of such series (or their respective Predecessor
      Securities) are registered at the close of business on such Special Record
      Date and shall no longer be payable pursuant to the following Clause (2).

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

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

Section 308. Persons Deemed Owners.

            Prior to due presentment of a 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 Security is
registered as the owner of such Security for the purpose of receiving payment of
principal of (and premium, if any) and (subject to Section 307) interest on such
Security and for all other purposes whatsoever, whether or not such Security 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. None of the Company, the Guarantor, the Trustee or any agent of the
Company, the Guarantor or the Trustee shall have any responsibility or liability
for any aspect of the records relating to or payments made on account of
beneficial ownership interests of a Security in global form or for maintaining,
supervising or receiving any records relating to such beneficial ownership
interests.

Section 309. Cancellation.

            All Securities surrendered for payment, redemption, registration of
transfer or exchange or for credit against any sinking fund payment shall, if
surrendered to any Person other than the Trustee, be delivered to the Trustee
and shall be promptly cancelled by it. The Company or the Guarantor may at any
time deliver to the Trustee for cancellation any Securities previously
authenticated and delivered hereunder which the Company or the Guarantor may
have acquired

                                      -28-
<PAGE>

in any manner whatsoever, and may deliver to the Trustee (or to any other Person
for delivery to the Trustee) for cancellation any Securities previously
authenticated hereunder which the Company has not issued and sold, and all
Securities so delivered shall be promptly cancelled by the Trustee. No
Securities shall be authenticated in lieu of or in exchange for any Securities
cancelled as provided in this Section, except as expressly permitted by this
Indenture. All cancelled Securities held by the Trustee shall be disposed of in
accordance with its normal procedures unless otherwise directed by a Company
Order.

Section 310. Computation of Interest.

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

Section 311. CUSIP Numbers.

            The Company in issuing the Securities may use a "CUSIP", "CINS", or
"ISIN" number (if then generally in use), and the Company and the Trustee shall
use such "CUSIP" "CINS", or "ISIN" number in notices of redemption or exchange
as a convenience to Holders; provided that any such notice shall state that no
representation is made as to the correctness of such "CUSIP" "CINS", or "ISIN"
number either as printed on the Securities or as contained in any notice of
redemption or exchange and that reliance may be placed only on the other
identification numbers printed on the Securities; and provided further that
failure to use "CUSIP" "CINS", or "ISIN" numbers in any notice of redemption or
exchange shall not affect the validity or sufficiency of such notice. The
Company shall promptly notify the Trustee of any change in "CUSIP" "CINS", or
"ISIN" number for the Securities.

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

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

            (3) the Company has delivered to the Trustee an Officers'

            Notwithstanding the satisfaction and discharge of this Indenture,
the obligations of the Company to the Trustee under Section 607, the obligations
of the Company to any Authenticating Agent under Section 614 and, if money shall

this Section, the obligations of the Trustee under Section 402 and the last
paragraph of Section 1003 shall survive.

Indenture, to the payment, either directly or through any Paying Agent

Trustee may determine, to the Persons entitled thereto, of the principal (and
premium, if any) and interest for whose payment such money has been deposited

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

      bankruptcy, insolvency, reorganization or other similar law or (B) a
      decree or order adjudging the Company or the Guarantor a bankrupt or
      insolvent, or approving as properly filed a petition seeking
      reorganization, arrangement, adjustment or composition of or in respect of
      the Company or the Guarantor under any applicable Federal or State law, or
      appointing a custodian, receiver, liquidator, assignee, trustee,

      winding up or liquidation of its affairs, and the continuance of any such
      decree or order for relief or any such other decree or order unstayed and
      in effect for a period of 90 consecutive days; or

            (6) the commencement by the Company or the Guarantor of a voluntary
      case or proceeding under any applicable Federal or State bankruptcy,

                                      -31-

      insolvency, reorganization or other similar law or of any other case or
      proceeding to be adjudicated a bankrupt or insolvent, or the consent by it
      to the entry of a decree or order for relief in respect of the Company or
      the Guarantor in an involuntary case or proceeding under any applicable
      Federal or State bankruptcy, insolvency, reorganization or other similar
      law or to the commencement of any bankruptcy or insolvency case or
      proceeding against it, or the filing by it of a petition or answer or
      consent seeking reorganization or relief under any applicable Federal or
      State law, or the consent by it to the filing of such petition or to the
      appointment of or taking possession by a custodian, receiver, liquidator,
      assignee, trustee, sequestrator or similar official of the Company or the
      Guarantor or of any substantial part of its respective property, or the
      making by it of an assignment for the benefit of creditors, or the
      admission by it in writing of its inability to pay its debts generally as
      they become due, or the taking of corporate action by the Company or the
      Guarantor in furtherance of any such action; or

            (7) the Guarantee of the Guarantor ceases to be in full force and
      effect, or the Guarantor shall deny or disaffirm its obligations under the
      Guarantee; or

            (8) the Company or the Guarantor defaults with respect to
      indebtedness for money borrowed having an aggregate principal amount of at
      least $25 million, or the Company or the Guarantor defaults under any
      mortgage, indenture or instrument under which the Company or the Guarantor
      may have issued, secured or evidenced indebtedness having an aggregate
      principal amount of at least $25 million, whether such indebtedness exists
      now or is created later, which default (A) results from the failure by the
      Company or the Guarantor to pay any part of the principal of such
      indebtedness when the principal became due after the expiration of any
      grace period or (B) causes the acceleration of such indebtedness, without,
      in the case of clause (A) above, such indebtedness being discharged or
      without, in the case of clause (B) above, such indebtedness being
      discharged or such acceleration having been rescinded or annulled, both
      within 10 days after there has been given, by registered or certified
      mail, to the Company or the Guarantor, as the case may be, by the Trustee
      or holders of at least 25% in aggregate principal amount of the
      Securities, a written notice specifying the default or acceleration and
      stating that such Notice is a " Notice of Default" hereunder; or

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

            Upon receipt by the Trustee of any Notice of Default pursuant to
this Section 501 with respect to Securities of a series all or part of which is
represented by a Global Security, a record date shall be established for
determining Holders of Outstanding Securities of such series entitled to join in
such Notice of Default, which record date shall be at the close of business on
the day the Trustee receives such Notice of Default. The Holders on such record
date, or their duly designated proxies, and only such Persons, shall be entitled
to join in such Notice of Default, whether or not such Holders remain Holders
after such record date; provided. however, that unless Holders of at least 25%
in principal amount of the Outstanding Securities of such series, or their
proxies, shall have joined in such Notice of Default prior to the date which is
the ninetieth

                                      -32-
<PAGE>

day after such record date, such Notice of Default shall automatically and
without further action by any Holder be cancelled and of no further effect.
Nothing in this paragraph shall prevent a Holder, or a proxy of a Holder, from
giving, (i) after expiration of such 90-day period, a new Notice of Default
identical to a Notice of Default which has been cancelled pursuant to the
proviso to the preceding sentence or (ii) during any such 90-day period, an
additional Notice of Default with respect to any new or different fact or
circumstance permitting the giving of a Notice of Default with respect to
Securities of such series, in either of which events a new record date shall be
established pursuant to the provisions of this Section 501.

Section 502. Acceleration of Maturity; Rescission and Annulment.

            If an Event of Default (other than an Event of Default specified in
Sections 501(5) and (6)) with respect to Securities of any series at the time
Outstanding occurs and is continuing, then and in every such case the Trustee or
the Holders of not less than 25% in principal amount of the Outstanding
Securities of that series may declare the principal amount (or, if any of the
Securities of that series are Original Issue Discount Securities, such portion
of the principal amount of such Securities as may be specified in the terms
thereof) of all of the Securities of that 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 Holders), and upon any such declaration such principal
amount (or specified amount) shall become immediately due and payable. If an
Event of Default specified in Section 501(5) or (6) occurs and is continuing,
then all the Securities shall ipso facto become due and payable immediately in
an amount equal to the principal amount (or, if any of the Securities of that
series are Original Issue Discount Securities, such portion of the principal
amount of such Securities as may be specified in the terms thereof) of the
Securities together with accrued and unpaid interest, if any, to the date the
Securities become due and payable, without any declaration or other act on the
part of the Trustee or any Holder. Thereupon, the Trustee may, at its
discretion, proceed to protect and enforce the rights of Holders of the
Securities by appropriate means.

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

                  (A) all overdue interest on all Securities of that series,

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

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

                                      -33-
<PAGE>

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

      and

            (2) all Events of Default with respect to Securities of that series,
      other than the non-payment of the principal of Securities of that series
      which have become due solely by such declaration of acceleration, have
      been cured or waived as provided in Section 513.

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

            Upon receipt by the Trustee of written notice declaring such an
acceleration, or rescission and annulment thereof, with respect to Securities of
a series all or part of which is represented by a Global Security, a record date
shall be established for determining Holders of Outstanding Securities of such
series entitled to join in such notice, which record date shall be at the close
of business on the day the Trustee receives such notice. The Holders on such
record date, or their duly designated proxies, and only such Persons, shall be
entitled to join in such notice, whether or not such Holders remain Holders
after such record date; provided, however, that unless such declaration of
acceleration, or rescission and annulment, as the case may be, shall have become
effective by virtue of the requisite percentage having joined in such notice
prior to the day which is the ninetieth day after such record date, such notice
of declaration of acceleration, or rescission and annulment, as the case may be,
shall automatically and without further action by any Holder be cancelled and of
no further effect. Nothing in this paragraph shall prevent a Holder, or a proxy
of a Holder, of Securities of any series from giving, (i) after expiration of
such 90-day period, a new written notice of declaration of acceleration, or
rescission and annulment thereof, as the case may be, that is identical to a
written notice which has been cancelled pursuant to the proviso to the preceding
sentence or (ii) during any such 90-day period an additional written notice of
declaration of acceleration with respect to any other Event of Default with
respect to Securities of such series, or an additional written notice of
rescission or annulment of any declaration of acceleration with respect to any
other Event of Default with respect to Securities of such series, in either of
which events a new record date shall be established pursuant to the provisions
of this Section 502.

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

            The Company covenants that if

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

            (2) default is made in the payment of the principal of (or premium,
      if any, on) any Security at the Maturity thereof,

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

                                      -34-
<PAGE>

interest, at the rate or rates prescribed therefor in such Securities, and, in
addition thereto, such further amount as shall be sufficient to cover the costs
and expenses of collection, including the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel.

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

            If an Event of Default with respect to Securities of any series
occurs and is continuing, the Trustee may in its discretion proceed to protect
and enforce its rights and the rights of the Holders of Securities of such
series by such appropriate judicial proceedings as the Trustee shall deem most
effectual to protect and enforce any such rights, whether for the specific
enforcement of any covenant or agreement in this Indenture or in aid of the
exercise of any power granted herein, or 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 relating to the Company, the Guarantor or any other
obligor upon the Securities or the property of the Company, the Guarantor or of
such other obligor or their creditors, the Trustee (irrespective of whether the
principal of the Securities shall then be due and payable as therein expressed
or by declaration or otherwise and irrespective of whether the Trustee shall
have made any demand on the Company or the Guarantor for the payment of overdue
principal or interest) shall be entitled and empowered, by intervention in such
proceeding or otherwise,

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

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

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or
other similar official in any such judicial proceeding is hereby authorized by
each Holder to make such payments to the Trustee and, in the event that the
Trustee shall consent to the making of such payments directly to the Holders, to
pay to the Trustee any amount due it for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, and any other
amounts due the Trustee under Section 607.

            Nothing herein contained shall be deemed to authorize the Trustee to
authorize or consent to or accept or adopt on behalf of any Holder any plan of
reorganization, arrangement,

                                      -35-
<PAGE>

adjustment or composition affecting the Securities or the rights of any Holder
thereof or to authorize the Trustee to vote in respect of the claim of any
Holder in any such proceeding.

Section 505. Trustee May Enforce Claims Without Possession of Securities.

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

Section 506. Application of Money Collected.

            Any money collected by the Trustee pursuant to this Article shall be
applied in the following order, at the date or dates fixed by the Trustee and,
in case of the distribution of such money on account of principal (or premium,
if any) or interest, upon presentation of the Securities and the notation
thereon of the payment if only partially paid and upon surrender thereof if
fully paid:

            FIRST: To the payment of all amounts due the Trustee under Section
      607, including the reasonable fees and expenses of its counsel; and

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

Section 507. Limitation on Suits.

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

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

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

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

            (4) the Trustee for 90 days after its receipt of such notice,
      request and offer of indemnity has failed to institute any such
      proceeding; and

                                      -36-
<PAGE>

            (5) no direction inconsistent with such written request has been
      given to the Trustee during such 90-day period by the Holders of a
      majority in principal amount of the Outstanding Securities of that series;

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

Section 508. Unconditional Right of Holders to Receive Principal, Premium and
Interest.

            Notwithstanding any other provision in this Indenture, the Holder of
any Security shall have the right, which is absolute and unconditional, to
receive payment of the principal of (and premium, if any) and (subject to
Section 307) interest on such Security on the Stated Maturity or Maturities
expressed in such Security (or, in the case of redemption, on the Redemption
Date) and to institute suit for the enforcement of any such payment, and such
rights shall not be impaired without the consent of such Holder.

Section 509. Restoration of Rights and Remedies.

            If the Trustee or any Holder has instituted any proceeding to
enforce any right or remedy under this Indenture and such proceeding has been
discontinued or abandoned for any reason, or has been determined adversely to
the Trustee or to such Holder, then and in every such case, subject to any
determination in such proceeding, the Company, the Trustee and the Holders shall
be restored severally and respectively to their former positions hereunder and
thereafter all rights and remedies of the Trustee and the Holders shall continue
as though no such proceeding had been instituted.

Section 510. Rights and Remedies Cumulative.

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

Section 511. Delay or Omission Not Waiver.

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

                                      -37-

Section 512. Control by Holder.

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

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

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

            Upon receipt by the Trustee of any written notice directing the
time, method or place of conducting any such proceeding or exercising any such
trust or power, with respect to Securities of a series all or part of which is
represented by a Global Security, a record date shall be established for
determining Holders of Outstanding Securities of such series entitled to join in
such notice, which record date shall be at the close of business on the day the
Trustee receives such notice. The Holders on such record date, or their duly
designated proxies, and only such Persons, shall be entitled to join in such
notice, whether or not such Holders remain Holders after such record date;
provided, however, that unless the Holders of a majority in principal amount of
the Outstanding Securities of such series shall have joined in such notice prior
to the day which is the ninetieth day after such record date, such notice shall
automatically and without further action by any Holder be cancelled and of no
further effect. Nothing in this paragraph shall prevent a Holder, or a proxy of
a Holder, from giving, (i) after expiration of such 90-day period, a new notice
identical to a notice which has been cancelled pursuant to the proviso to the
preceding sentence or (ii) during any such 90-day period, a new direction
contrary to or different from such direction, in either of which events a new
record date shall be established pursuant to the provisions of this Section 512.

Section 513. Waiver of Past Defaults.

            Subject to Section 502, the Holders of a majority in principal
amount of the Outstanding Securities of any series may, by notice to the
Trustee, waive an existing or past default with respect to the Securities of
such series and its consequences, except a default

            (1) in the payment of principal of (or premium, it any) or interest
      on any Security of such series, or in the deposit of any sinking fund
      payment when and as due,

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

            (3) in respect of an existing or past default described in clause
      (4), (5) or (6) of Section 501, which may be waived by the Holders of a
      majority in principal amount of all Outstanding Securities voting together
      as a single class.

            The Company may, but shall not be obligated to, fix a record date
for the purpose of determining the Persons entitled to waive any past default
hereunder. If a record

                                      -38-
<PAGE>

date is fixed, the Holders on such record date, or their duly designated
proxies, and only such Persons, shall be entitled to waive any default
hereunder, whether or not such Holders remain Holders after such record date;
provided, however that unless such majority in principal amount shall have
waived such default prior to the date which is the ninetieth day after such
record date, any such waiver previously given shall automatically and without
further action by any Holder be cancelled and of no further effect.

            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. 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 iii
its discretion require, in any suit for the enforcement of any right or remedy
under this Indenture, or in any suit against the Trustee for any action taken,
suffered or omitted by it as Trustee, the filing by any party litigant in such
suit of an undertaking to pay the costs of such suit, and that such court may in
its discretion assess reasonable costs, including reasonable attorneys' fees,
against any party litigant in such suit, having due regard to the merits and
good faith of the claims or defenses made by such party litigant; but the
provisions of this Section shall not apply to any suit instituted by the
Company, to any suit instituted by the Trustee, to any suit instituted by any
Holder, or group of Holders, holding in the aggregate more than 10% in principal
amount of the Outstanding Securities of any series, or to any suit instituted by
any Holder for the enforcement of the payment of the principal of (or premium,
if any) or interest on any Security on or after the Stated Maturity or
Maturities expressed in such Security (or, in the case of redemption, on or
after the Redemption Date).

Section 515. Waiver of Stay or Extension Laws.

            The Company and the Guarantor covenant (to the extent that they may
lawfully do so) that they 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 and
the Guarantor (to the extent that it may lawfully do so) hereby expressly waive
all benefit or advantage of any such law and covenants that they 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.

                                  ARTICLE SIX

                                  The Trustee

Section 601. Certain Duties and Responsibilities.

            The duties and responsibilities of the Trustee shall be as provided
by the Trust Indenture Act.

                                      -39-
<PAGE>

            Notwithstanding the foregoing, no provision of this Indenture shall
require the Trustee to expend or risk its own funds or otherwise incur any
financial liability in the performance of any of its duties hereunder, or in the
exercise of any of its rights or powers, if it shall have reasonable grounds for
believing that repayment of such funds or adequate indemnity against such risk
or liability is not reasonably assured to it. Whether or not therein expressly
so provided, every provision of this Indenture relating to the conduct or
affecting the liability of or affording protection to the Trustee shall be
subject to the provisions of this Section.

Section 602. Notice of Defaults.

            If a default occurs hereunder with respect to Securities of any
series, the Trustee shall give the Holders of Securities of such series notice
of such default as and to the extent provided in the Trust Indenture Act,
provided, however, that in the case of any default of the character specified in
Section 501(4) with respect to Securities of such series, no such notice to
Holders shall be given until at least 30 days after the occurrence thereof. For
the purpose of this Section, the term "default" means any event which is, or
after notice or lapse of time or both would become, an Event of Default with
respect to Securities of such series.

Section 603. Certain Rights of Trustee.

            Subject to the provisions of Section 601:

            (a) the Trustee may rely and shall be protected in acting or

      instrument, opinion, report, notice, request, direction, consent, order,

      evidenced by a Board Resolution;

            (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 be herein specifically prescribed) may, in the absence of
      bad faith on its part, rely upon an 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 this Indenture at the request or
      direction of any of the Holders pursuant to this Indenture, unless such
      Holders shall have offered to the Trustee reasonable security or indemnity
      against the costs, expenses and

                                      -40-
<PAGE>

      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, debenture, note, other evidence of indebtedness or other paper or
      document, but the Trustee, in its discretion, may make such further
      inquiry or investigation into such facts or matters as it may see fit,
      and, if the Trustee shall determine to make such further inquiry or
      investigation. it shall be entitled to examine the books, records and
      premises of the Company or the Guarantor, or both, 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

      it hereunder;

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

            (i) the Trustee shall not be charged with knowledge of any default
      or Event of Default with respect to the Securities unless either (1) a
      Responsible Officer 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 by any Holder of the
      Securities; and

            (j) the permissive rights of the Trustee enumerated herein shall not
      be construed as duties.

Section 604. Not Responsible for Recitals or Issuance of Securities.

            The recitals contained herein and in the Securities, except the
Trustee's certificates of authentication, shall be taken as the statements of
the Company or the Guarantor, as the case may be, and the Trustee or any
Authenticating Agent assumes no responsibility for their correctness. The
Trustee makes no representations as to the validity or sufficiency of this
indenture or of the Securities or the Guarantees. The Trustee or any
Authenticating Agent shall not be accountable for the use or application by the
Company of Securities or the proceeds thereof.

Section 605. May Hold Securities.

            The Trustee, any Authenticating Agent, any Paying Agent, any
Security Registrar or any other agent of the Company or the Guarantor, in its
individual or any other capacity, may become the owner or pledgee of Securities
and, subject to Sections 608 and 613, 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, Security Registrar or such other agent.

                                      -41-
<PAGE>

Section 606. Money Held in Trust.

            Money held by the Trustee in trust hereunder need not be segregated
from other funds except to the extent required by law. The Trustee shall be
under no liability for interest on any money received by it hereunder except as
otherwise agreed with the Company or the Guarantor, as the case may be.

Section 607. Compensation and Reimbursement.

            The Company and the Guarantor, joint and severally, agree

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

            (2) except as otherwise expressly provided herein, to reimburse 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 its negligence or bad
      faith; and

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

            When the Trustee incurs expenses or renders services in connection
with an Event of Default specified in Section 501(5) and 501(6), the expenses
(including the reasonable charges and expenses of its counsel) and the
compensation for the services are intended to constitute expenses of
administration under any applicable Federal or State bankruptcy, insolvency,
reorganization, or other similar law.

            To secure the Company's and Guarantor's payment obligations in this
Section 607, the Trustee shall have a lien prior to the Securities on all money
or property held or collected by the Trustee, in its capacity as Trustee, except
money or property held in trust to pay principal of, premium, if any, and
interest on particular Securities.

            The provisions of this Section 607 shall survive the resignation or
removal of the Trustee and the termination of this Indenture.

            The Trustee for the Securities of any series issued hereunder shall
be subject to the provisions of Section 310(b) of the Trust Indenture Act during
the period of time provided for therein. In determining whether the Trustee has
a conflicting interest as defined in Section 310(b)

                                      -42-
<PAGE>

of the Trust Indenture Act with respect to the Securities of any series, there
shall be excluded this Indenture with respect to
Securities of more than one series.

Section 609. Corporate Trustee Required; Eligibility.

            There shall at all times be one (and only one) trustee hereunder
with respect to the Securities of each series, which may be the Trustee
hereunder for Securities of one or more other series, which shall be a
corporation organized and doing business under the laws of the United States of
America, any State thereof or the District of Columbia, authorized under such
laws (including the Trust Indenture Act) to exercise corporate trust powers,
having a combined capital and surplus of at least $50,000,000. If such
corporation publishes reports of condition at least annually, pursuant to law or
to the requirements of said supervising or examining authority, then for the
purposes of this Section, and the extent permitted by the Trust Indenture Act,
the combined capital and surplus of such corporation shall be deemed to be its
combined capital and surplus as set forth in its most recent report of condition
so published. If at any time the Trustee shall cease to be eligible in
accordance with the provisions of this Section, it shall resign immediately in
the manner and with the effect hereinafter specified in this Article.

Section 610. Resignation and Removal; Appointment of Successor.

            (a) No resignation or removal of the Trustee and no appointment of a
successor Trustee pursuant to this Article shall become effective until the
acceptance of appointment by the successor Trustee in accordance with the
applicable requirements of Section 611.

            (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 611 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 to
the Company.

            (d) If at any time:

            (1) the Trustee shall fail to comply with Section 608 and shall fail
      to resign after written request therefor by the Company, by the Guarantor
      or by any Holder who has been a bona fide Holder of a Security for at
      least six months, or

            (2) the Trustee shall cease to be eligible under Section 609 and
      shall fail to resign after written request thereof by the Company, the
      Guarantor or by any such Holder, or

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

                                      -43-
<PAGE>

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

            (e) If the Trustee shall resign, be removed or become incapable of
      acting. or if a vacancy shall occur in the office of Trustee for any
      cause, with respect to the Securities of one or more series, the Company,
      by 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 611. 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
      611, become the successor Trustee with respect to the Securities of such
      series and to that extent supersede the successor Trustee appointed by the
      Company. If no successor Trustee with respect to the Securities of any
      Series shall have been so appointed by the Company or the Holders and
      accepted appointment in the manner required by Section 611, any Holder who
      has been a bona fide Holder of a Security of such series for at least six
      months may, on behalf of himself and all others similarly situated,
      petition any court of competent jurisdiction for the appointment of a
      successor Trustee with respect to the Securities of such series.

            (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
to all Holders of Securities of such series in the manner provided in Section
106. Each notice shall include the name of the successor Trustee with respect to
the Securities of such series and the address of its Corporate Trust Office.

Section 611. Acceptance of Appointment by Successor.

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

            (b) In case of the appointment hereunder of a successor Trustee with
respect to the Securities of one or more (but not all) series, the Company, the
Guarantor, the retiring Trustee and each successor Trustee with respect to the
Securities of one or more series shall execute and deliver an indenture
supplemental hereto wherein each successor Trustee shall accept such appointment
and which (1) shall contain such provisions as shall be necessary or

                                      -44-
<PAGE>

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

            (c) Upon request of any such successor Trustee, the Company 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) and (b) of this Section, as the case may be.

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

Section 612. Merger, Conversion, Consolidation or Succession to Business.

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

Section 613. Preferential Collection of Claims Against Company or Guarantor.

Section 614. Appointment of Authenticating Agent.

            At any time when any of the Securities remain Outstanding the
Trustee may appoint an Authenticating Agent or Agents with respect to one or
more series of Securities which shall be authorized to act on behalf of the
Trustee to authenticate Securities of such series issued upon exchange,
registration of transfer or partial redemption thereof 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 shall at all times be a corporation organized and doing business
under the laws of the United States of America, any State thereof or the
District of Columbia, authorized under such laws to act as Authenticating Agent,
having a combined capital and surplus of not less than $50,000,000 and subject
to supervision or examination by Federal or State authority. If such
Authenticating Agent publishes reports of condition at least annually, pursuant
to law or to the requirements of said supervising or examining authority, then
for the purposes of this Section, the combined capital and surplus of such
Authenticating Agent shall be deemed to be its combined capital and surplus as
set forth in its most recent report of condition so published. If at any time an
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section, such Authenticating Agent shall resign immediately
in the manner and with the effect specified in this Section.

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

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

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

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

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

      such request, a list of similar form and content as of a date not more
      than 15 days prior to the time such list is furnished;

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

            (i) afford such applicants access to the information preserved at
      the time by the Trustee in accordance with Section 702(a), or

      by the Trustee in accordance with Section 702(a), and as to the
      approximate cost of mailing to such Holders the form of proxy or other
      communication, if any, specified in such application.

            If the Trustee shall elect not to afford such applicants access to
such information, the Trustee shall, upon the written request of such

the Trustee, such mailing would be contrary to the best interest of the Holders
or would be in violation of applicable law. Such written statement shall specify
the basis of such opinion. If the Commission, after opportunity for a hearing
upon the objections specified in the written statement so filed, shall enter an
order refusing to sustain any of such objections or if, after the entry of an
order sustaining one or more of such objections, the Commission shall find,
after notice and opportunity for hearing, that all the objections so sustained
have been met and shall enter an order so declaring, the Trustee shall mail
copies of such material to all such Holders with reasonable promptness after the
entry of such order and the renewal of such tender; otherwise the Trustee shall
be relieved of any obligation or duty to such applicants respecting their
application.

            (c) Every Holder of Securities, by receiving and holding the same,
agrees with the Company, the Guarantor and the Trustee that neither the Company,
the Guarantor nor the Trustee nor any agent of either of them shall be held
accountable by reason of the disclosure of any such information as to the names
and addresses of the Holders in accordance with Section 702(b) regardless of the

be held accountable by reason of mailing any material pursuant to a request made
under Section 702(b).

provision of this Indenture which has expressly been included solely for the
benefit of one or more particular series of Securities, or which modifies the
rights of the Holders of Securities of such series with respect to such covenant

Indenture of the Holders of Securities of any other series.

            The Company may, but shall not be obligated to, fix a record date
for the purpose of determining the Persons entitled to consent to any indenture
supplemental hereto. If a record date is fixed, the Holders on such record date,
or their duly designated proxies, and only such Persons, shall be entitled to
consent to such supplemental indenture, whether or not such Holders remain
Holders after such record date; provided, however, that unless such consent
shall have become effective by virtue of the requisite percentage having been
obtained prior to the date which is the ninetieth day after such record date,
any such consent previously given shall, automatically and without further
action by any Holder, be cancelled and of no further effect.

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

            Securities authenticated and delivered after the execution of any
supplemental indenture pursuant to this Article may, and shall if required by
the Trustee, bear a notation in form approved by the Trustee as to any matter
provided for in such supplemental indenture. If the Company shall so determine,

executed by the Company, the Guarantees endorsed thereon may be executed by the
Guarantor and such Securities may be authenticated and delivered by the Trustee
in exchange for Outstanding Securities of such series.

Securities an office or agency where Securities of that series may be presented
or surrendered for payment, where Securities of that series may be surrendered
for registration of transfer or exchange and where notices and demands to or
upon the Company in respect of the Securities of that series and this Indenture
may be served. The Company will give prompt written notice to the Trustee of the
location, and any change in the location, of such office or agency. If at any
time the Company shall fail to maintain any such required office or agency or
shall fail to furnish the Trustee with the address thereof, such presentations,
surrenders, notices and demands may be made or served at the Corporate Trust
Office of the Trustee, and the Company hereby appoints the Trustee as its agent
to receive all such presentations, surrenders, notices and demands.

            The Company may also from time to time designate one or more other
offices or agencies where the Securities of one or more series may be presented
or surrendered for any or all such purposes and may from time to time rescind
such 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 will give prompt written notice to the Trustee of any such
designation or rescission and of any change in the location of any such other
office or agency.

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

            If the Company or the Guarantor shall at any time act as its own
Paying Agent with respect to any series of Securities, it will, on or before
each due date of the principal of (and premium, if any) or interest on any of
the Securities of that series, segregate and hold in trust for the benefit of
the Persons entitled thereto a sum sufficient to pay the principal (and premium,
if any) or interest so becoming due until such sums shall be paid to such
Persons or otherwise disposed of as herein provided and will promptly notify the
Trustee of its action or failure so to act.

            Whenever the Company and the Guarantor shall have one or more Paying
Agents for any series of Securities, it will, on or before each due date of the
principal of (and premium, if any) or interest on any Securities of that series,
deposit with a Paying Agent a sum sufficient to pay the principal (and premium,
if any) or interest so becoming due, such sum to be held in trust for the
benefit of the Persons entitled to such principal, premium or interest, and
(unless such Paying Agent is the Trustee) the Company will promptly notify the
Trustee of its action or failure so to act.

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

            (1) hold all sums held by it for the payment of the principal of
      (and premium, if any) or interest on Securities of that 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 herein provided;

            (2) give the Trustee notice of any default by the Company (or any
      other obligor upon the Securities of that series) in the making of any
      payment of principal (and premium, if any) or interest on the Securities
      of that series; and

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

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

            Any money deposited with the Trustee or any Paying Agent, or then
held by the Company or the Guarantor, in trust for the payment of the principal
of (and premium, if any) or interest on any Security of any series and remaining
unclaimed for one year after such principal (and premium, if any) or interest
has become due and payable shall be paid to the Company or the Guarantor, as the
case may be, on Company Request or Guarantor Request, as the case may be, or (if
then held by the Company or the Guarantor) shall be discharged from such trust;
and the Holder of such Security shall thereafter, as an unsecured general
creditor, look only to the

                                      -55-
<PAGE>

Company (or to the Guarantor pursuant to its Guarantee) 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 as trustee thereof,
shall thereupon cease.

Section 1004. Corporate Existence.

            Subject to Article Eight, each of the Company and the Guarantor will
do or cause to be done all things necessary to preserve and keep in full force
and effect its corporate existence and all licenses and permits material to the
normal conduct of its business; provided, however, that neither the Company nor
the Guarantor shall not be required to preserve any such right or franchise if
the Board of Directors shall determine that the preservation thereof is no
longer desirable in the conduct of the business of the Company and the
Guarantor, as the case may be, and that the loss thereof is not disadvantageous
in any material respect to the Holders.

Section 1005. Limitation on Liens.

            The Company will not, and will not permit any Significant Subsidiary
to, directly or indirectly, create, issue, assume, incur or guarantee any
indebtedness for money borrowed which is secured by a mortgage, pledge, lien,
security interest or other encumbrance of any nature on any of the Voting Stock
of a Significant Subsidiary unless the Outstanding Securities (together with
such other indebtedness of the Company or such Significant Subsidiary then
existing or thereafter created which is not subordinate to the Outstanding
Securities as the Company may elect) shall be secured equally and ratably with
(or prior to) such secured indebtedness for money borrowed so long as such
secured indebtedness for money borrowed shall be so secured. This Section shall
not prevent the sale or other disposition of a Significant Subsidiary.

            For purposes of this Section, "Voting Stock" means all classes of
stock (including any and all shares, interests, participations or other
equivalents (however designated) of corporate stock) then outstanding of a
Significant Subsidiary normally entitled to vote in elections of directors. For
purposes of this Section, "SIGNIFICANT SUBSIDIARY" means Platinum Underwriters
Reinsurance Inc. and any other Subsidiary the assets of which, determined as of
the last day of the most recent calendar quarter ended at least 30 days prior to
the date of such determination and in accordance with generally accepted
accounting principles as in effect on the last day of such calendar quarter,
exceed 20% of the Consolidated Assets of the Company. For purposes of this
Section, "CONSOLIDATED ASSETS OF THE COMPANY" means the assets of the Company
and its consolidated subsidiaries, to be determined as of the last day of the
most recent calendar quarter ended at least 30 days prior to the date of such
determination and in accordance with generally accepted accounting principles as
in effect on the last day of such calendar quarter.

Section 1006. Statement by Officers as to Default.

            Each of the Company and the Guarantor will deliver to the Trustee,
within 120 days after the end of each fiscal year of the Company and the
Guarantor, as the case may be, ending after the date hereof, an Officers'
Certificate, stating whether or not to the best knowledge of the signers thereof
the Company or the Guarantor, as the case may be, is in default in the
performance and observance of any of the terms, provisions and conditions of
Sections 1001 to 1006, inclusive, and if the Company or the Guarantor, as the
case may be, shall be in default,

                                      -56-
<PAGE>

specifying all such defaults and the nature and status thereof of which they may
have knowledge.

Section 1007. Waiver of Certain Covenants.

            The Company and the Guarantor may omit in any particular instance to
comply with any term, provision or condition set forth in Sections 1002 to 1005,
inclusive, if before the time for such compliance the Holders of a majority in
principal amount of the Outstanding Securities shall, by Act of such Holders,
waive compliance in such instance with such term, provision or condition. In the
event that there shall be included in this Indenture any covenant, other than a
covenant to pay principal, premium (if any) and interest, solely for the benefit
of one or more, but less than all, series of Securities, then, unless otherwise
expressly provided with respect to such covenant, the Company and the Guarantor
may similarly omit in any particular instance to comply with any term, provision
or condition of such covenant if before the time of such compliance the holders
of a majority in principal amount of all Outstanding Securities entitled to the
benefit of such covenant, by Act of such Holders, acting together as a single
class, waive compliance in such instance with such term, provision or condition.
No such waiver contemplated by this Section 1007 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.

            The Company may, but shall not be obligated to, fix a record date
for the purpose of determining the Persons entitled to waive any such term,
provision or condition. If a record date is fixed, the Holders on such record
date, or their duly designated proxies, and only such Persons, shall be entitled
to waive any such term, provision or condition hereunder, whether or not such
Holders remain Holders after such record date; provided, however, that unless
the Holders of at least a majority in principal amount of (i) the Outstanding
Securities or (ii) the Outstanding Securities of such series, as the case may
be, shall have waived such term, provision or condition prior to the date which
is 90 days after such record date, any such waiver previously given shall
automatically and without further action by any Holder be cancelled and of no
further effect.

                                 ARTICLE ELEVEN

                            Redemption of Securities

Section 1101. Applicability of Article.

            Securities of any series which are redeemable before their Stated

in accordance with this Article.

Section 1102. Election to Redeem; Notice to Trustee.

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

                                      -57-
<PAGE>

In the case of any redemption of Securities prior to the expiration of any
restriction on such redemption provided in the terms of such Securities or
elsewhere in this Indenture, the Company shall furnish the Trustee with an
Officers' Certificate evidencing compliance with such restriction.

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

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

            The Trustee shall promptly notify the Company in writing of the
Securities selected for redemption and, in the case of any Securities selected
for partial redemption, the principal amount thereof to be redeemed.

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

Section 1104. Notice of Redemption.

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

            All notices of redemption shall state:

            (1) the Redemption Date,

            (2) the Redemption Price,

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

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

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

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

                                      -58-
<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 any 10:00 a.m., New York City time, on Redemption
Date, the Company or the Guarantor shall deposit with the Trustee or with a
Paying Agent (or, if the Company or the Guarantor is acting as its own Paying
Agent, segregate and hold in trust as provided in Section 1003) an amount of
money sufficient to pay the Redemption Price of, and (except if the Redemption
Date shall be an Interest Payment Date) accrued interest on, all the Securities
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 and the Guarantor shall default in the payment of the Redemption Price
and accrued interest) such Securities shall cease to bear interest. Upon
surrender of any such Security for redemption in accordance with said notice,
such Security shall be paid by the Company or the Guarantor at the Redemption
Price, together with accrued interest to the Redemption Date; provided, however,
that installments of interest whose Stated Maturity is on or prior to the
Redemption Date shall be payable to the Holders of such Securities, or one or
more Predecessor Securities, registered as such at the close of business on the
relevant Record Dates according to their terms and the provisions of Section
307.

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

Section 1107. Securities Redeemed in Part.

            Any Security which is to be redeemed only in part shall be
surrendered at a Place of Payment therefor (with, if the Company, the Guarantor
or the Trustee so requires, due endorsement by, or a written instrument of
transfer in form satisfactory to the Company, the Guarantor and the Trustee duly
executed by, the Holder thereof or his attorney duly authorized in writing), and
the Company shall execute, and the Trustee shall authenticate and deliver to the
Holder of such Security without service charge, a new Security or Securities of
the same series and of like tenor, of any authorized denomination as requested
by such Holder, in aggregate principal amount equal to and in exchange for the
unredeemed portion of the principal of the Security so surrendered having
endorsed thereon a Guarantee or Guarantees executed by the Guarantor.

Section 1201. Applicability of Article.

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

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

Section 1202. Satisfaction of Sinking Fund Payments with Securities.

            The Company or the Guarantor (1) may deliver Outstanding Securities
of a series (other than any previously called for redemption) and (2) may apply
as a credit Securities of a series which have been redeemed either at the
election of the Company pursuant to the terms of such Securities or through the
application of permitted optional sinking fund payments pursuant to the terms of
such Securities, in each case in satisfaction of all or any part of any sinking
fund payment with respect to the Securities of such series required to be made
pursuant to the terms of such Securities as provided for by the terms of such
series; provided that such Securities have not been previously so credited.
Such Securities shall be received and credited for such purpose by the Trustee
at the Redemption Price specified in such Securities for redemption through
operation of the sinking fund and the amount of such sinking fund payment shall
be reduced accordingly.

Section 1203. Redemption of Securities for Sinking Fund.

            Not less than 90 days prior to each sinking fund payment date for
any series of Securities, the Company will deliver to the Trustee an Officers'
Certificate specifying the amount of the next ensuing sinking fund payment for
that series pursuant to the terms of that series, the portion thereof, if any,
which is to be satisfied by payment of cash and the portion thereof, if any,
which is to be satisfied by delivering and crediting Securities of that series
pursuant to Section 1202 and will also deliver to the Trustee any Securities to
be so delivered. Not less than 60 days before each such sinking fund payment
date the Trustee shall select the Securities to be redeemed upon such sinking
fund payment date in the manner specified in Section 1103 and cause notice of
the redemption thereof to be given in the name of and at the expense of the
Company in the manner provided in Section 1104. Such notice having been duly
given, the redemption of such Securities shall be made upon the terms and in the
manner stated in Sections 1106 and 1107.

                                   Guarantees

Section 1301. Guarantee.

            The Guarantor hereby absolutely, fully and unconditionally and
irrevocably guarantees to each Holder of a Security authenticated and delivered
by the Trustee, and to the Trustee on behalf of each such Holder, (a) the due
and punctual payment of the principal of, premium, if any, and interest, if any,
on each such Security and the due and punctual payment of any sinking fund
payments provided for pursuant to the terms of such Security when and as the
same shall become due and payable, whether at the Stated Maturity, by
declaration of acceleration, call for redemption or otherwise, (b) the due and
punctual payment of interest on overdue principal of and interest on each such
Security, if any, if lawful, and (c) the due and punctual payment of any and all
other payments due to the Holder of each such Security all in accordance with
the terms of such Security and of this Indenture. In case of the failure of the
Company punctually to make any such payment of principal (or premium, if any) or
interest, if any, or sinking fund payment, 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 are a
guaranty of payment and not a guaranty of collection or performance and shall be
unconditional and absolute, irrespective of the validity, regularity or
enforceability of such Security or this Indenture or any limitation of the
Company thereunder or any limitations on the method or terms of payment
thereunder which may now or hereafter be caused or imposed in any manner
whatsoever, 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
insolvency or bankruptcy of the Company, any right to require a proceeding first
against the Company, protest or notice with respect of such Security or the
indebtedness evidenced thereby or with respect to any sinking fund payment
required pursuant to the terms of such Security and all demands whatsoever, and
covenants that this Guarantee will not be discharged except by complete
performance of the obligations contained in the Securities and in the
Guarantees.

            Without limiting the generality of the foregoing, the Guarantor
hereby agrees that the obligations of the Guarantor hereunder shall not be
released, affected or impaired by assignment or transfer in whole or in part of
such Security whether or not made without notice to or the consent of the
Guarantor and shall not be subject to any reduction, limitation, impairment or
termination for any reason, including any claim of waiver, release, surrender,
alteration or compromise, and shall not be subject to any defense of, including,
but not limited to, setoff, counterclaim, recoupment or termination whatsoever,
and that such obligations shall not be released, affected or impaired regardless
of whether or not any Holder or such Security, or anyone on behalf of any such
Holder shall have instituted any suit, action or proceeding or exhausted its
remedies or taken any steps to enforce any rights against the Company or any
other person to compel any such performance or observance or to collect all or
part of any such

                                      -61-
<PAGE>

amount, either pursuant to the provisions of this Indenture or such Security or
at law or in equity, and regardless of any other condition or contingency, or by
reason of the invalidity, illegality or unenforceability of such Security or
this Indenture or otherwise and that such obligations shall not be discharged or
impaired or otherwise affected by the failure of the Trustee or any Holder of
such Security to assert any claim or demand or to enforce any remedy under this
Indenture or such Security, any other guarantee or any other agreement, by any
waiver, amendment, indulgence or modification (whether material or otherwise) of
any provision of any thereof, by any default, failure or delay, willful or
otherwise, in the performance of any obligations under this Indenture, such
Security or this Guarantee, or by the voluntary or involuntary liquidation, sale
or other disposition of all or substantially all of the assets of the Company or
the Guarantor, or any receivership, insolvency, bankruptcy, reorganization, or
other similar proceedings, affecting the Company or any of its assets, or the
release of any property from the lien and security interest created by this
Indenture or such Security or of any other security for such Security, or the
release or discharge of the Company or the Guarantor from the performance or
observance of any agreement, covenant, term or condition contained in this
Indenture or such Security by operation of law, or the merger or consolidation
of the Company or the Guarantor, or any other cause, whether similar or
dissimilar to the foregoing, or by any other act or omission that may or might
in any manner or to any extent vary the risk or obligations of the Guarantor or
that would otherwise operate as a discharge of a surety or guarantor as a matter
of law or equity (other than the performance of the obligations contained in
such Security and in this Guarantee).

            If the Trustee or the Holder of any Security is required by any
court or otherwise to return to the Company or the Guarantor, or any custodian,
receiver, liquidator, trustee, sequestrator or other similar official acting in
relation to the Company or the Guarantor, any amount paid to the Trustee or such
Holder in respect of a Security, this Guarantee, to the extent theretofore
discharged, shall be reinstated in full force and effect. The Guarantor further
agrees, to the fullest extent that it lawfully may do so, that, as between the
Guarantor, on the one hand, and the Holders and the Trustee, on the other hand,
the maturity of the obligations guaranteed hereby may be accelerated as provided
in Article Five hereof for the purposes of this Guarantee, notwithstanding any
stay, injunction or other prohibition extant under any applicable bankruptcy law
preventing such acceleration in respect of the obligations guaranteed hereby.

            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 the Securities of such Series
pursuant to the provisions of the Guarantees of this 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 premium, if any) and interest, if any, on all Securities of
such series issued hereunder shall have been paid in full.

Section 1302. Execution and Delivery of Guarantees.

            To evidence its guarantee provided in Section 1301, the Guarantor
hereby agrees to execute the Guarantees, in a form established pursuant to
Section 201, to be endorsed on each Security authenticated and delivered by the
Trustee. Each such Guarantee shall be executed on behalf of the Guarantor by its
Chairman of the Board, Chief Executive Officer, President or one of its Vice
Presidents or its Treasurer under a facsimile of its corporate seal reproduced
thereon and attested by its Secretary or one of its Deputy Secretaries. The
signature of any of these officers on the Guarantees may be manual or
facsimile.

                                      -62-
<PAGE>

            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 ceased to
hold such offices prior to the authentication and delivery of the Securities
upon which such Guarantees are endorsed or did not hold such offices at the
date of such Securities.

            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 1301 shall remain in full force and effect
notwithstanding any failure to endorse on each Security a notation of such
Guarantee.

                       Defeasance and Covenant Defeasance

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

            If pursuant to Section 301 provision is made for either or both of
(a) defeasance of the Securities of a series under Section 1402 or (b) covenant
defeasance of the Securities of a series under Section 1303, then the provisions
of such Section or Sections, as the case may be, together with the other
provisions of this Article Fourteen, shall be applicable to the Securities of
such series, and the Company may at its option by Board Resolution, at any time,
with respect to the Securities of such series, elect to have either Section 1402
(if applicable) or Section 1403 (if applicable) be applied to the Outstanding
Securities of such series upon compliance with the conditions set forth below in
this Article Fourteen.

Section 1402. Defeasance and Discharge.

            Upon the Company's exercise of the above option applicable to this
Section, the Company shall be deemed to have been discharged from its
obligations with respect to the Outstanding Securities of such series on and
after the date the conditions precedent set forth below 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 the Outstanding Securities of such series and to have satisfied
all its other obligations under such Securities and this Indenture insofar as
such Securities are concerned and the Trustee, at the expense of the Company,
shall execute proper instruments acknowledging the same), except for the
following which shall survive until otherwise terminated or discharged
hereunder: (A) the rights of Holders of Outstanding Securities of such series to
receive, solely from the trust fund described in Section 1404 as more fully set
forth in such Section, payments of the principal of (and premium, if any) and
interest on such Securities when such payments are due, (B) the Company's
obligations with respect to such Securities under Sections 304, 305, 306, 1002
and 1003 and such obligations as shall be ancillary thereto, (C) the rights,
powers, trusts, duties, immunities and other provisions in respect of the
Trustee hereunder and (D) this Article Fourteen. Subject to compliance with this
Article Fourteen, the Company may exercise its option under this Section 1402
notwithstanding the prior exercise of its option under Section 1403 with respect
to the Securities of such series. Following a defeasance, payment of the
Securities of such series may not be accelerated because of an Event of Default.

Section 1403. Covenant Defeasance.

            Upon the Company's exercise of the above option applicable to this
Section, the Company shall be released from its obligations under (i) Section
1005, (ii) the occurrence of an event specified in Section 501(4) (with respect
to Section 1005) shall not be deemed an Event of Default and (iii) any other
section, clause or provision applicable to such Securities that are determined
pursuant to Section 301 to be subject to this provision with respect to the
Outstanding Securities of such series on and after the date the conditions
precedent set forth below are satisfied (hereinafter, "COVENANT DEFEASANCE").
For this purpose, such covenant defeasance means that, with respect to the
Outstanding Securities of such series, 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 Clause whether directly or indirectly by reason of
any reference elsewhere herein to any such Section or Clause or by reason of any
reference in any such Section or Clause to any other provision herein or in any
other document, but the remainder of this Indenture and such Securities shall be
unaffected thereby. Following a covenant defeasance, payment of the Securities
of such series may not be accelerated because of or by reference to the Sections
specified above in this Section 1403.

Section 1404. Conditions to Defeasance or Covenant Defeasance.

            The following shall be the conditions precedent to application of
either Section 1402 or Section 1403 to the Outstanding Securities of such
series:

            (1) the Company shall irrevocably have deposited or caused to be
      deposited with the Trustee (or another trustee satisfying the requirements
      of Section 609 who shall agree to comply with the provisions of this
      Article Thirteen 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,
      (A) money in an amount, or (B) U.S. Government Obligations 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, money in an amount, or (C) a combination
      thereof, sufficient, without reinvestment, in the opinion of a nationally
      recognized firm of independent public accountants expressed in a written
      certification thereof delivered to the Trustee, to pay and discharge, and
      which shall be applied by the Trustee (or other qualifying trustee) to pay
      and discharge, (i) the principal of (and premium, if any) and interest on
      the Outstanding Securities of such series to maturity or redemption, as
      the case may be, and (ii) any mandatory sinking fund payments or analogous
      payments applicable to the Outstanding Securities of such series on the
      due dates thereof. Before such a deposit the Company may make
      arrangements satisfactory to the Trustee for the redemption of Securities
      at a future date or dates in accordance with Article Eleven, which shall
      be given effect in applying the foregoing. For this purpose, "U.S.
      GOVERNMENT OBLIGATIONS" means securities that are (x) direct obligations
      of the United States of America for the payment of which its full faith
      and credit is pledged or (y) obligations of a Person controlled or
      supervised by and acting as an agency or instrumentality of the United
      States of America the payment of which is unconditionally guaranteed as a
      full faith and credit obligation by the United States of America, which,
      in either case, are not callable or redeemable at the option of the issuer
      thereof, and shall also include a

                                      -64-
<PAGE>

      depository receipt issued by a bank (as defined in Section 3(a)(2) of the
      Securities Act of 1933, as amended) as custodian with respect to any such
      U.S. Government Obligation or a specific payment of principal of or
      interest on any such U.S. Government Obligation held by such custodian for
      the account of the holder of such depository receipt, provided that
      (except as required by law) such custodian is not authorized to make any
      deduction from the amount payable to the holder of such depository receipt
      from any amount received by the custodian in respect of the U.S.
      Government Obligation or the specific payment of principal of or interest
      on the U.S. Government Obligation evidenced by such depository receipt.

            (2) No Event of Default or event which with notice or lapse of time
      or both would become an Event of Default with respect to the Securities of
      such series shall have occurred and be continuing (A) on the date of such
      deposit or (B) insofar as subsections 501(5) and (6) are concerned, at
      any time during the period ending on the 121st day after the date of such
      deposit or, if longer, ending on the day following the expiration of the
      longest preference period applicable to the Company in respect of such
      deposit (it being understood that the condition in this clause (B) is a
      condition subsequent and shall not be deemed satisfied until the
      expiration of such period).

            (3) Such defeasance or covenant defeasance shall not (A) cause the
      Trustee for the Securities of such series to have a conflicting interest
      as defined in 0 or for purposes of the Trust Indenture Act with respect to
      any securities of the Company or (B) result in the trust arising from such
      deposit to constitute, unless it is qualified as, a regulated investment
      company under the Investment Company Act of 1940, as amended.

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

            (5) In the case of an election under Section 1402, the Company shall
      have delivered to the Trustee an Opinion of Counsel stating that (x) the
      Company has received from, or there has been published by, the Internal
      Revenue Service a ruling, or (y) since the date 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 the Outstanding Securities of such series 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 time as would have been the case if
      such defeasance had not occurred.

            (6) In the case of an election under Section 1403, the Company shall
      have delivered to the Trustee an Opinion of Counsel to the effect that the
      Holders of the Outstanding Securities of such series 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

                                      -65-
<PAGE>

      same manner and at the same times as would have been the case if such
      covenant defeasance had not occurred.

            (7) Such defeasance or covenant defeasance shall be effected in
      compliance with any additional terms, conditions or limitations which may
      be imposed on the Company in connection therewith pursuant to Section 301.

            (8) The Company shall have delivered to the Trustee an Officers'
      Certificate and an Opinion of Counsel, each stating that all conditions
      precedent provided for relating to either the defeasance under Section
      1402 or the covenant defeasance under Section 1403 (as the case may be)
      have been complied with.

Section 1405. Deposited Money and U.S. Government Obligations to be Held in
              Trust; Other Miscellaneous Provisions.

            Subject to the provisions of the last paragraph of Section 1003, all
money and U.S. Government Obligations (including the proceeds thereof) deposited
with the Trustee (or other qualifying trustee -- collectively, for purposes of
this Section 1405, the "TRUSTEE") pursuant to Section 1404 in respect of the
Outstanding Securities of such series shall be held in trust and applied by the
Trustee, in accordance with the provisions of such Securities and this
Indenture, to the payment, either directly or through any Paying Agent (but not
including the Company acting as its own Paying Agent) as the Trustee may
determine, to the Holders of such Securities, of all sums due and to become due
thereon in respect of principal (and premium, if any) and interest, but such
money need not be segregated from other funds except to the extent required by
law.

            The Company shall pay and indemnify the Trustee against any tax, fee
or other charge imposed on or assessed against the money or U.S. Government
Obligations deposited pursuant to Section 1404 or the principal and interest
received in respect thereof.

            Anything herein to the contrary notwithstanding, the Trustee shall
deliver or pay to the Company from time to time upon Company Request any money
or U.S. Government Obligations held by it as provided in Section 1404 which, in
the opinion of a nationally recognized firm of independent public accountants
expressed in a written certification thereof delivered to the Trustee, are in
excess of the amount thereof which would then be required to be deposited to
effect an equivalent defeasance or covenant defeasance.

Section 1406. Reinstatement.

            If the Trustee or the Paying Agent is unable to apply any money in
accordance with Section 1402 or 1403 by reason of any order or judgment or any
court or governmental authority enjoining, restraining or otherwise prohibiting
such application, then the Company's obligations under the Securities of such
series shall be revived and reinstated as though no deposit had occurred
pursuant to this Article Fourteen until such time as the Trustee or Paying Agent
is permitted to apply all such money in accordance with Section 1402 or 1403;
provided, however, that if the Company makes any payment of principal of (and
premium, if any) any such Security following the reinstatement of its
obligations, the Company shall be subrogated to the rights of the Holders of
such Securities to receive such payment from the money held by the Trustee or
the Paying Agent.

      "Interest Rate" shall have the meaning set forth in Section 2.5.

      "Over-Allotment Option" shall mean the option granted to the underwriters
      pursuant to the Underwriting Agreement to purchase up to an additional
      750,000 Normal Units.

      "Purchase Contract Agreement" shall mean the Purchase Contract Agreement,

                                   ARTICLE II

                   GENERAL TERMS AND CONDITIONS OF THE NOTES

Section 2.1. Designation, Principal Amount and Authorized Denomination.

      There is hereby authorized a series of Securities designated the 5.25%
Senior Guaranteed Notes due 2007, limited in aggregate principal amount to
$125,000,000, which amount to be issued shall be as set forth in any Company
Order for the authentication and delivery of Notes pursuant to the Base
Indenture and which amount may be increased by up to $18,750,000 in the event
the Over-Allotment option is exercised. The Notes shall be issuable only in
registered form and without coupons in denominations of $1000 and any integral
multiples thereof except that an interest in a Note held as part of a Normal
Unit represents an ownership interest of 1/40th, or 2.5%, of a Note in aggregate
principal amount of $1000 and will therefore correspond to the stated amount of
$25 per Normal Unit.

Section 2.2. Maturity.

      The Stated Maturity Date of the Notes will be November 16, 2007.

Section 2.3. Form and Payment.

Depository, or its nominee, and deposited with the Trustee, as custodian for
DTC, for credit by DTC to the respective accounts of beneficial owners of the
Separate Notes represented thereby (or such other accounts as they may direct).

      (b) The principal of and the interest on the Notes shall be payable at the
Office or agency of the Company maintained for that purpose in any coin or
currency of the United States of America that at the time of payment is legal
tender for the payment of public or private debts; provided, however, that
payment of interest may be made at the option of the Company by check mailed to
the registered Holder at such address as shall appear in the Security Register
or by wire transfer to an account appropriately designated by the Holder
entitled thereto.

Section 2.4. Global Note.

      (a) DTC shall serve as the initial Depository for the Global Note.

      (b) Unless and until it is exchanged for definitive Notes in registered
form in accordance with Section 305 of the Base Indenture, a Global Note may be
transferred, in whole but not in part, only to another nominee of the
Depository, or to a successor

                                       3

Depository selected or approved by the Company or to a nominee of such
successor Depository.

Section 2.5. Interest and Interest Rate Reset.

      (a) Each Note will bear interest from its Issue Date or from the most
recent Interest Payment Date to which interest has been paid or duly provided
for, as the case may be, initially at the rate of 5.25% per annum (the "Interest
Rate") up to but excluding the Reset Date; provided, however, that in the event
that a Last Failed Remarketing occurs, each Note shall continue to bear interest
at the Interest Rate until the principal of the Notes is paid or made available
for payment. In the event the Notes are successfully remarketed pursuant to the
Purchase Contract Agreement and the Remarketing Agreement, each Note shall bear
interest at the Reset Rate from and including the Reset Date to the date on
which the principal of the Notes is paid or made available for payment; provided
that any principal and installment of interest which is overdue shall bear
interest (to the extent that payment of such interest is enforceable under
applicable law) at the Interest Rate up to but excluding the Reset Date, if any,
and thereafter at the Reset Rate, from the dates such amounts are due until they
are paid or made available for payment, and such interest shall be payable on
demand. Interest on the Notes initially shall be payable quarterly in arrears on
February 16, May 16, August 16 and November 16 of each year (each, an "Interest
Payment Date"), commencing February 16, 2003, through and including November 16,
2005 and then semi-annually in arrears on the Interest Payment Dates of May 16
and November 16 of each year, commencing November 15, 2005, until the principal
thereof is paid or made available for payment.

      (b) The amount of interest payable for any period on any Interest Payment
Date will be computed on the basis of a 360-day year consisting of twelve 30-day
months. Except as provided in the following sentence, the amount of interest
payable for any period shorter than a full quarterly or semi-annual, as
applicable, period for which interest is computed will be computed on the basis
of the actual number of days elapsed in such a 90-day or 180-day period, as
applicable. In the event that any date on which interest is payable on the Notes
is not a Business Day, then payment of interest payable on such date will be
made on the next succeeding day which is a Business Day (and without any
interest or other payment in respect of any such delay), except that, if such
Business Day is in the next succeeding calendar year, such payment shall be made
on the immediately preceding Business Day, in each case with the same force and
effect as if made on such date.

      The Notes do not have the benefit of any sinking fund obligation.

      PLATINUM UNDERWRITERS FINANCE, INC., a Delaware corporation (the
"Company", which term includes any successor corporation under the Indenture
hereinafter referred to), for value received, hereby promises to pay to JPMorgan
Chase Bank, the principal sum of __________ dollars ($____) on November 16, 2007
(such date is hereinafter referred to as the "Stated Maturity Date"), and to pay
interest on said principal sum from November 1, 2002, or from the most recent
interest payment date initially at the rate of 5.25% per annum (the "Interest
Rate") up to, but excluding, the Reset Date; provided, however, that in the
event a Last Failed Remarketing occurs, this Note shall continue to bear
interest at the Interest Rate until the principal of the Notes is paid or made
available for payment. In the event the Notes are successfully remarketed
pursuant to the Purchase Contract Agreement and the Remarketing Agreement, this
Note shall bear interest at the Reset Rate, from and including the Reset Date to

provided that any principal and installment of interest which is overdue shall

2005, and then semi-annually in arrears on the Interest Payment Dates of May 16
and November 16 of each year, commencing on May 16, 2006, until the principal
hereof is paid or made available for payment. The amount of interest payable for
any period on any Interest Payment Date shall be computed on the basis of a
360-day year consisting of twelve 30-day months. Except as provided in the
following sentence, the amount of interest payable for any period shorter than a
full quarterly or semi-annual period, as applicable, for which interest is
computed will be computed on the basis of the actual number of days elapsed in
such a 90-day or 180-day period, as applicable. In the event that any date on
which interest is payable on this Note is not a Business Day, then payment of
interest payable on such date will be made on the next succeeding day that is a
Business Day (and without any interest or other payment in respect of any such
delay), except that, if such Business Day is in the next succeeding calendar
year, such payment shall be made on the immediately preceding Business Day, in
each case with the same force and effect as if made on such date. The interest
installment so payable, and punctually paid or duly provided for, on any
Interest Payment Date will, as provided in the Indenture, be paid to the person
in whose name this Note is registered at the close of business on the regular
record date for such interest installment, which as long as any Notes are
represented by a Global Note shall be the close of business on the Business Day
next preceding such Interest Payment Date; provided, however, if pursuant to the

punctually paid or duly provided for shall forthwith cease to be payable to the
registered Holders on such regular record date and may be paid to the Person in
whose name this Note is registered at the close of business on a special record
date to be fixed by the Trustee for the payment of such defaulted interest,
notice whereof shall be given to the registered Holders of this series of Notes
not less than 10 days prior to such special record date, or may be paid at any
time in any other lawful manner not inconsistent with the requirements of any
securities exchange on which the Notes may be listed, and upon such notice as
may be required by such exchange all as more fully provided in the Indenture.
The principal of and the interest on this Note shall be payable at the office
or agency of the Company maintained for that purpose in any coin or currency of
the United States of America that at the time of payment is legal tender for
payment of public and private debts; provided, however, that payment of interest
may be made at the option of the Company by check mailed to the registered
Holder at such address as shall appear in the Register or by wire transfer to an
account appropriately designated by the Holder entitled thereto.

                            (FORM OF REVERSE OF NOTE)

      This Note is one of a duly authorized series of the Senior Guaranteed
Notes of the Company (herein sometimes referred to as the "Securities"),
specified in the Indenture hereinafter referred to, all issued or to be issued
in one or more series under and pursuant to an Indenture dated as of October 10,
2002 (the "Base Indenture"), duly executed and delivered among the Company,
Platinum Underwriters Holdings, Ltd., as guarantor (herein called the
"Guarantor") and JPMorgan Chase Bank, as Trustee (the "Trustee") (such Base
Indenture as supplemented by the First Supplemental Indenture, dated November 1,
2002, the "Indenture"), to which Indenture and all indentures supplemental
thereto reference is hereby made for a description of the rights, limitations of
rights, obligations, duties and immunities thereunder of the Trustee, the
Company and the Holders of the Securities. By the terms of the Indenture, the
Securities are issuable in series that may vary as to amount, date of maturity,
rate of interest and in other respects as provided in the Indenture. This series
of Securities is limited in aggregate principal amount as specified in said
First Supplemental Indenture.

      The Securities of this series were initially issued as components of the
Company's equity security units that are in the form of Normal Units, each such
Normal Unit initially consisting of (a) a stock purchase contract (each, a
"Purchase Contract") under which (i) the holder will agree to purchase from the
Company on November 16, 2005, a specified number of newly issued common shares,
par value $0.01 per share, of the Company and (ii) the Company will pay to the
holder quarterly contract adjustment payments and (b) a 1/40, or 2.5%, ownership
interest in a Security of this series of $1,000 principal amount. In accordance
with the terms of the Purchase Contract Agreement, on their initial issuance the
Securities of this series were pledged by the Purchase Contract Agent, on behalf
of the holders of the Normal Units, to State Street Bank and Trust Company, as
collateral agent, custodial agent and securities intermediary (the "Collateral
Agent"), pursuant to the Pledge Agreement, dated as of November 1, 2002 (the
"Pledge Agreement"), among the Company, the Purchase Contract Agent and the
Collateral Agent, to secure such holders' obligations to purchase common shares
of the Company under the Purchase Contracts. Pursuant to the Remarketing
Agreement, the Remarketing Agent shall use its commercially reasonable best
efforts to remarket the Securities of this series that are included in Normal
Units at a specified price on certain dates, all as specified in Section 5.4(b)
of the Purchase Contract Agreement. Pursuant to Section 4.5(d) of the Pledge
Agreement, Holders of all other Securities of this series may elect to have such
Securities remarketed in accordance with the procedures set forth therein.

      If a Tax Event (as herein defined) shall occur and be continuing, the
Company may, at its option, redeem the Notes then Outstanding in whole (but not
in part) at any time ("Tax Event Redemption") at the Redemption Price (as herein
defined). If such Tax Event Redemption occurs prior to a successful remarketing
pursuant to Section 5.4 of the Purchase Contract Agreement, the Redemption Price
payable with respect to the Notes pledged to the Collateral Agent under the
Pledge Agreement will be paid to the

                                       9
<PAGE>

Collateral Agent on the Tax Event Redemption Date on or prior to 12:00 p.m., New
York City time, by wire transfer in immediately available funds at such place
and at such account as may be designated by the Collateral Agent in exchange for
the Notes pledged to the Collateral Agent; in such event, the Collateral Agent
shall apply such Redemption Price pursuant to the terms of the Purchase Contract
Agreement and the Pledge Agreement.

      Notice of any redemption will be mailed at least 30 days but not more than
60 days before the date of redemption (the "Tax Event Redemption Date") to each
registered Holder of Notes of this Series to be redeemed at its registered
address as more fully provided in the Indenture. Unless the Company defaults in
payment of the Redemption Price, on and after the Tax Event Redemption Date
interest shall cease to accrue on such Notes of this Series.

      "Quotation Agent" means Goldman, Sachs & Co. or any of its successors or
any other primary U.S. government securities dealer in The City of New York
selected by the Company.

      "Redemption Price" means, for each Note, the product of (i) the principal
amount of such Note and (ii) a fraction whose numerator is the applicable
Treasury Portfolio Purchase Price (as herein defined) and whose denominator is
the applicable Tax Event Redemption Principal Amount (as herein defined).

      "Tax Event" means the receipt by the Company of an opinion of a nationally
recognized tax counsel experienced such matters, to the effect that there is
more than an insubstantial risk that interest payable by the Company on the
Notes on the next Interest Payment Date will not be deductible, in whole or in
part, by the Company for United States federal income tax purposes as a result
of (a) any amendment to, or change (including any announced proposed change) in,
the laws (or any regulations thereunder) of the United States or any political
subdivision or taxing authority thereof or therein affecting taxation (other
than any such amendment, change or announced proposed change to the so-called
"earnings stripping" provisions of Section 163(j) of the Internal Revenue Code,
which limit the ability of U.S. corporations to deduct interest on certain debt
owed to or guaranteed by related foreign persons), (b) any amendment to or
change in an official interpretation or application of such laws or regulations
by any legislative body, court, governmental agency or regulatory authority or
(c) any official interpretation, pronouncement or application that provides for
a position with respect to such laws or regulations that differs from the
generally accepted position on November 1, 2002, which amendment, change or
proposed change is effective or which interpretation or pronouncement is
announced on or after November 1, 2002.

      "Tax Event Redemption Principal Amount" means (i) in the case of a Tax
Event Redemption Date occurring prior to a successful remarketing of the Notes
pursuant to the Purchase Contract Agreement, the aggregate principal amount of
Notes included in Normal Units on such date, and (ii) in the case of a Tax Event
Redemption Date

                                       10
<PAGE>

occurring after a successful remarketing of the Notes pursuant to the Purchase
Contract Agreement, the aggregate principal amount of the Notes.

      "Treasury Portfolio Purchase Price" means the lowest aggregate price
quoted by a primary U.S. government securities dealer in New York City to the
Quotation Agent on the third Business Day immediately preceding the Tax Event
Redemption Date for the purchase of the Treasury Portfolio for settlement on the
Tax Event Redemption Date.

      "Treasury Portfolio" means: (i) if a Tax Event Redemption occurs prior to
a successful remarketing of the Notes pursuant to the provisions of the Purchase
Contract Agreement, a portfolio (A) of zero coupon U.S. Treasury securities
consisting of principal or interest strips of U.S. Treasury securities that
mature on or prior to November 16, 2005 in an aggregate amount equal to the
applicable Tax Event Redemption Principal Amount and (B) with respect to each
scheduled Interest Payment Date on the Notes that occurs after the Tax Event
Redemption Date and on or before November 16, 2005, interest or principal strips
of U.S. Treasury securities that mature on or prior to such Interest Payment
Date in an aggregate amount equal to the aggregate interest payment that would
be due on the applicable Tax Event Redemption Principal Amount on such date if
the interest rate of the Notes were not reset on the Reset Date, and (ii) solely
for purposes of determining the Treasury Portfolio Purchase Price in the case of
a Tax Event Redemption Date occurring after a successful remarketing of the
Notes pursuant to the Purchase Contract Agreement on November 16, 2005, a
portfolio (A) of zero coupon U.S. Treasury securities consisting of principal or
interest strips of U.S. Treasury securities that mature on or prior to the
Maturity Date in an aggregate amount equal to the applicable Tax Event
Redemption Principal Amount and (B) with respect to each scheduled Interest
Payment Date on the Notes that occurs after the Tax Event Redemption Date and on
or before the Maturity Date, interest or principal strips of U.S. Treasury
securities that mature on or prior to such Interest Payment Date in an aggregate
amount equal to the aggregate interest payment that would be due on the
applicable Tax Event Redemption Principal Amount of the Notes Outstanding on the
Tax Event Redemption Date.

      The Notes do not have the benefit of any sinking fund obligation.

      In case an Event of Default, as defined in the Indenture, shall have
occurred and be continuing, the principal of all of the Notes may be declared,
and upon such declaration shall become, due and payable, in the manner, with the
effect and subject to the conditions provided in the Indenture.

      The Indenture permits, with certain exceptions as therein provided, the
amendment thereof and the modification of the rights and obligations of the
Company and the Guarantor and the rights of the Holders of the Notes under the
Indenture at any time by the Company, the Guarantor and the Trustee with the
consent of the majority of the Holders in principal amount of the Notes at the
time Outstanding. The Indenture also contains provisions permitting the Holders
of specified percentages in aggregate principal amount of the Notes at the time
Outstanding, on behalf of the Holders of all

                                       11
<PAGE>

the Notes, to waive compliance by the Company or the Guarantor, or both, with
certain provisions of the Indenture and certain past defaults under the
Indenture and their consequences. Any such consent or waiver by the Holder of
this Note shall be conclusive and binding upon such Holder and upon all future
Holders of this Note and of any Note issued upon the registration of transfer
hereof or in exchange herefor or in lieu hereof, whether or not notation of such
consent or waiver is made upon this Note.

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

      As provided in the Indenture and subject to certain limitations therein
set forth, this Note is transferable by the registered Holder hereof on the
Register of the Company, upon surrender of this Note for registration of
transfer at the office or agency of the Trustee in the City of New York and
State of New York accompanied by a written instrument or instruments of transfer
in form satisfactory to the Company or the Trustee duly executed by the
registered Holder hereof or his attorney duly authorized in writing, and
thereupon one or more new Notes of authorized denominations and for the same
aggregate principal amount and series will be issued to the designated
transferee or transferees. No service charge will be made for any such transfer,
but the Company may require payment of a sum sufficient to cover any tax,
assessment or other governmental charge payable in relation thereto.

      Prior to due presentment for registration of transfer of this Note, the
Company, the Guarantor, the Trustee, any paying agent and the Registrar may deem
and treat the registered holder hereof as the absolute owner hereof (whether or
not this Note shall be overdue and notwithstanding any notice of ownership or
writing hereon made by anyone other than the Registrar) for the purpose of
receiving payment of or on account of the principal hereof and premium, if any,
and interest due hereon and for all other purposes, and neither the Company, the
Guarantor nor the Trustee nor any paying agent nor any Registrar shall be
affected by any notice to the contrary.

      No recourse shall be had for the payment of the principal of or the
interest on this Note, or for any claim based hereon, or otherwise in respect
hereof, or based on or in respect of the Indenture, against any incorporator,
shareholder, officer or director, past, present or future, as such, of the
Company or the Guarantor or of any predecessor or successor corporations,
whether by virtue of any constitution, statute or rule of law, or by the
enforcement of any assessment or penalty or otherwise, all such liability being,
by the acceptance hereof and as part of the consideration for the issuance
hereof, expressly waived and released.

      The Indenture imposes certain limitations on the ability of the Company
and the Guarantor to, among other things, merge or consolidate with any other
Person or sell, assign, transfer, lease or convey all or substantially all of
its properties and assets. All such covenants and limitations are subject to a
number of important qualifications and

                                       12
<PAGE>

exceptions. The Company and Guarantor must report periodically to the Trustee on
compliance with the covenants in the Indenturee.

      The Notes of this series are issuable only in registered form without
coupons, in denominations of $1000 and any integral multiple thereof except that
an interest in a Note held as part of a Normal Unit represents an ownership
interest of 1/40th, or 2.5%, of a Note in aggregate principal amount of $1000
and will therefore correspond to the stated amount of $25 per Normal Unit. As
provided in the Indenture and subject to certain limitations therein set forth,
Notes of this series so issued are exchangeable for a like aggregate principal
amount of Notes of this series of a different authorized denomination, as
requested by the Holder surrendering the same.

      [If Note is a Global Note, insert -- This Note is a Global Note and is
subject to the provisions of the Indenture relating to Global Notes, including
the limitations in Section 305 of the Base Indenture on transfers and exchanges
of Global Notes.]

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

      This Note and the Guarantee endorsed herein shall be governed by and
construed in accordance with the laws of the State of New York, without giving
effect to conflicts of laws principles thereof.

                                   GUARANTEE

      For value received, Platinum Underwriters Holdings, Ltd., a corporation
organized under the laws of Bermuda (herein called the "Guarantor", which term
includes any successor under the Indenture referred to in the Note upon which
this Guarantee is endorsed), hereby absolutely, fully and unconditionally and
irrevocably guarantees to the Holder of the Note upon which this Guarantee is
endorsed, and to the Trustee on behalf of such Holder, (a) the due and punctual
payment of the principal of and interest (and, if applicable, the Redemption
Price) on such Note, whether at the Stated Maturity or by acceleration, call for
redemption or otherwise, (b) the due and punctual payment of interest on overdue
principal of and interest on such Note, if any, if lawful, and (c) the due and
punctual payment of any and all other payments due to the Holder, all in
accordance with the terms of such Note and of the Indenture. In case of the
failure of the Company punctually to make any such payment of principal,
premium, if any, or interest, if any, 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 are a guaranty
of payment and not a guaranty of collection or performance and shall be
unconditional and absolute, irrespective of the validity, regularity or
enforceability of such Note or the Indenture or any limitation of the Company
thereunder or any limitation on the method or terms of payment thereunder which
may now or hereafter be caused or imposed in any manner whatsoever, the absence
of any action to enforce the same, any waiver or consent by the Holder of such
Note or by the Trustee with respect to any provisions thereof or of the
Indenture, the obtaining of any judgment against the Company or any action to
enforce the same or any other circumstance 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 insolvency or
bankruptcy of the Company, any right to require a proceeding first against the
Company, protest or notice with respect to such Note or the indebtedness
evidenced thereby and all demands whatsoever, and covenants that this Guarantee
will not be discharged except by complete performance of the obligations
contained in such Note and in this Guarantee. Without limiting the generality of
the foregoing, the Guarantor hereby agrees that the obligations of the Guarantor
hereunder shall not be released, affected or impaired by assignment or transfer
