respect to any series of Securities, then the Trustee's Certificate of
Authentication by such Authenticating Agent on all Securities of each such
series shall be in substantially the following form:

                                        Authorized Signatory

        Section 2.4     Securities Issuable in the Form of Global Securities.

        (a)     If the Company shall establish pursuant to Section 3.1 that the
Securities of a particular series are to be issued in whole or in part as one or
more Global Securities, then the Company shall execute, and the Trustee shall,
in accordance with Section 3.3 and the Company Order deliver to the Trustee
thereunder, authenticate and make available for delivery, one or more Global
Securities, each of which (i) shall represent an aggregate principal amount
equal to the aggregate principal amount of the Outstanding Securities of such
series to be represented by such Global Security and may also provide that the
aggregate amount of Outstanding Securities represented thereby may from time to
time be increased or reduced to reflect exchanges, (ii) shall be registered in
the name of the Depository or its nominee, (iii) shall be delivered by the
Trustee to the Depository or pursuant to the Depository's instruction and (iv)
if required by the Depository, shall bear a legend reflecting the Depository's
interest in such Global Security.

        (b)     Notwithstanding any provision of Section 3.6, any Global
Security thereof may be transferred, in whole but not in part, and in the manner
provided in Section 3.6, only to another nominee of the Depository for such
series or Tranche, or to a successor Depository for such series selected or
approved by the Company or to a nominee of such successor Depository.

        (c)     If at any time the Depository for Securities of a series or
Tranche thereof notifies the Company that it is unwilling or unable to continue
as Depository for Securities of such series or Tranche or if at any time the
Depository shall no longer be registered or in good

                                      -12-

<PAGE>

standing under the Exchange Act, or other applicable statute or regulation, and
a successor Depository is not appointed by the Company within 90 days after the
Company receives such notice or becomes aware of such condition, as the case may
be, this Section shall no longer be applicable to the Securities of such series
or Tranche and the Company will execute, and the Trustee, upon receipt of a
Company Order for the authentication and delivery of individual Securities of
such series or Tranche, will authenticate and make available for delivery,
Securities of such series or Tranche, in authorized denominations, and in an
aggregate principal amount equal to the aggregate principal amount of the Global
Security or Global Securities of such series or Tranche in exchange for such
Global Security or Global Securities.

                The Company may at any time determine that Securities of any
series or Tranche thereof shall no longer be represented by one or more Global
Securities and that the provisions of this Section shall no longer apply to the
Securities of such series or Tranche. In such event the Company will execute and
the Trustee, upon receipt of a Company Order for the authentication and delivery
of individual Securities of such series or Tranche, will authenticate and make
available for delivery Securities of such series or Tranche, in authorized
denominations, and in an aggregate principal amount equal to the aggregate
principal amount of the Global Security or Global Securities of such series or
Tranche in exchange for such Global Security.

                If specified by the Company pursuant to Section 3.1 with respect
to a series of Securities or Tranche thereof, the Depository for such series or
Tranche may surrender a Global Security for such series or Tranche in exchange
in whole or in part for individual Securities of such series or Tranche on such
terms as are acceptable to the Company and such Depository. Thereupon, the
Company shall execute, and the Trustee shall authenticate and make available for
delivery, without service charge,

                (i)     to each Person specified by such Depository a new
        individual Security or Securities of the same series or Tranche, of any
        authorized denomination as requested by such Person in aggregate
        principal amount equal to and in exchange for such Persons' beneficial
        interest in the Global Security; and

                (ii)    to such Depository a new Global Security in a
        denomination equal to the difference, if any, between the principal
        amount of the surrendered Global Security and the aggregate principal
        amount of individual Securities delivered to Holders thereof.

                In any exchange provided for in any of the preceding paragraphs
of this Section, the Company will execute and the Trustee will authenticate and
make available for delivery individual Securities in registered form in
authorized denominations.

                Upon the exchange of a Global Security for individual
Securities, such Global Security shall be cancelled by the Trustee. Individual
Securities issued in exchange for a Global Security pursuant to this Section
shall be registered in such names and in such authorized denominations as the
Depository for such Global Security shall instruct the Trustee.

                                      -13-

The Trustee shall make such Securities available for delivery to the Persons in
whose names such Securities are so registered.

                With respect to Securities of a series subject to a Periodic
Offering, such resolution of the Board of Directors or indenture supplemental
hereto may provide general terms or parameters and may provide that the specific
terms of particular Securities, and the Persons authorized to determine such
terms or parameters, may be determined in accordance with or pursuant to the
Company Order referred to in Section 3.1.

                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 authority granted in, such resolution of the Board of
Directors or in any such indenture supplemental hereto.

                Anything herein to the contrary notwithstanding, the Trustee
shall be under no obligation to authenticate and deliver Securities of any
series the terms of which, established as contemplated by this Section, would
affect the rights, duties, obligations, liabilities or immunities of the Trustee
under this Indenture.

        Section 3.2     Form and Denominations.

        In the absence of any specification pursuant to Section 3.1 with respect
to the Securities of any series, the Securities of such series shall be issuable
in fully registered form, without coupons, in denominations of $1,000 and any
integral multiple thereof.

        Section 3.3     Authentication, Dating and Delivery of Securities.

        At any time and from time to time after the original execution and
delivery of this Indenture, the Company may deliver Securities of any series,
executed by the Company, to the Trustee for authentication. Except as otherwise
provided in this Article, the Trustee shall thereupon authenticate and make
available for delivery, or cause to be authenticated and delivered, said
Securities to or upon a Company Order, without any further action by the
Company; provided, however, that the Trustee shall authenticate and make
available for delivery Securities of such series for original issue from time to
time in the aggregate principal amount established for such series pursuant to
such procedures, acceptable to the Trustee and to such recipients, as may be
specified from time to time by a Company Order. The maturity dates, original
issue dates, interest rates and any other terms of the Securities of such series
shall be determined by or pursuant to such Company Order and procedures. If
provided for in such procedures, such Company Order may authorize authentication
and delivery pursuant to oral instructions from the Company or its duly
authorized agent, which instructions shall be promptly confirmed in writing.

        In authenticating such Securities and accepting the responsibilities
under this Indenture in relation to such Securities, the Trustee shall be
provided with, prior to the initial authentication of such Securities, and
(subject to Section 7.1) shall be fully protected in relying upon:

        (a)     a Board Resolution relating thereto;

                                      -17-

<PAGE>

        (b)     an Officer's Certificate or an executed supplemental indenture
setting forth the terms of such Securities as provided in Section 3.1;

        (c)     an Officer's Certificate which shall state that all conditions
precedent provided for in this Indenture relating to the issuance of such
Securities have been complied with, that no Event of Default with respect to any
series of Securities has occurred and is continuing and that the issuance of
such Securities does not constitute and will not result in (i) any Event of
Default or any event or condition, which, upon the giving of notice or the lapse
of time or both, would become an Event of Default or (ii) any default under the
provisions of any other instrument or agreement by which the Company is bound;
and

        (d)     an Opinion of Counsel, which shall state:

                (i)     that the form and the terms of such Securities have been
        duly authorized by the Company and have been established in conformity
        with the provisions of this Indenture;

                (ii)    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 binding obligations of the Company enforceable in accordance
        with their terms, except to the extent enforceability may be limited by
        applicable bankruptcy, insolvency, reorganization, moratorium,
        arrangement, fraudulent conveyance, fraudulent transfer and other
        similar laws affecting the enforcement of creditors' rights generally
        and by general principles of equity (regardless of whether
        enforceability is considered in a proceeding in equity or at law);

                (iii)   that no consent, approval, authorization, order,
        registration or qualification of or with any court or any governmental
        agency or body having jurisdiction over the Company is required for the
        execution and delivery of such Securities by the Company, except such as
        have been obtained (and except that no opinion need be expressed as to
        state securities or "blue sky" laws); and

                (iv)    all applicable laws and requirements in respect of the
        execution and delivery by the Company of such Securities have been
        complied with;

        Notwithstanding the provisions of Section 3.1 and of the immediately
preceding paragraph, with respect to Securities of a series subject to a
Periodic Offering, the Trustee shall be provided with the Officer's Certificate
otherwise required pursuant to Section 3.3(c) and the Opinion of Counsel
required by this Section 3.3(d) only once at or prior to the time of the first
authentication and delivery of such Securities (provided that such Opinion of
Counsel addresses the authentication and delivery of all such Securities) and
that, in lieu of the opinions described in clauses (ii) and (iii) above, Counsel
may opine that:

                (x)     when the terms of such Securities shall have been
established pursuant to a Company Order or Orders or pursuant to such procedures
as may be specified from time to time by a Company Order or Orders, all as
contemplated by and in accordance with the

                                      -18-

<PAGE>

instrument or instruments delivered pursuant to clause (i) above, such terms
will have been duly authorized by the Company and will have been established in
conformity with the provisions of this Indenture; and

                (y)     when such Securities shall have been authenticated and
delivered by the Trustee in accordance with this Indenture and the Company Order
or Orders or the specified procedures referred to in paragraph (x) above and
issued and delivered by the Company in the manner and subject to any conditions
specified in such Opinion of Counsel, such Securities will constitute valid
obligations of the Company enforceable in accordance with their terms except to
the extent enforceability may be limited by applicable bankruptcy, insolvency,
reorganization, moratorium and other similar laws affecting the enforcement of
creditors rights generally and by the effect of general principles of equity
(regardless of whether enforceability is considered in a proceeding in equity or
at law).

        With respect to Securities of a series subject to a Periodic Offering,
the Trustee may conclusively rely, as to the authorization by the Company of any
of such Securities, the forms and terms thereof, the validity thereof and the
compliance of the authentication and delivery thereof with the terms and
conditions of this Indenture, upon the Opinion or Opinions of Counsel, the
Officer's Certificate and the certificates and other documents delivered
pursuant to this Section 3.3 at or prior to the time of the first authentication
and delivery of Securities of such series until any of such opinions,
certificates or other documents have been superseded or revoked or expire by
their terms; provided, however, that any request by the Company to the Trustee
to authenticate and deliver Securities of such series shall constitute a
representation and warranty by the Company that as of the date of such request
the statements made in the most recent Officer's Certificate delivered pursuant
to Section 3.3(c) are true and correct as if made on and as of the date thereof.

        The Trustee shall have the right to decline to authenticate and make
available for delivery any Securities under this Section if the Trustee, being
advised by counsel, determines that such action would expose the Trustee to
personal liability.

        Each Security shall be dated the date of its authentication, except as
otherwise provided pursuant to Section 3.1 with respect to the series of which
such Security is a part and except that any substitute Security under Section
3.7 shall be dated so that neither gain nor loss in interest shall result from
any mutilation, destruction, loss or theft of the relevant Predecessor Security.

        Section 3.4     Execution of Securities.

        The Securities shall be signed in the name of and on behalf of the
Company by both (a) its president or any vice president and (b) its treasurer,
any assistant treasurer, its secretary or any assistant secretary, under its
corporate seal which may, but need not, be attested. Such signatures may be the
manual or facsimile signatures of such officers. The seal of the Company may be
in the form of a facsimile thereof and may be impressed, affixed, imprinted or
otherwise reproduced thereon. Typographical and other minor errors or defects in
any such reproduction

                                      -19-

<PAGE>

of the seal or any such signature shall not affect the validity or
enforceability of any Security that has been duly authenticated and delivered by
the Trustee.

        In case any officer of the Company who shall have signed any of the
Securities shall cease to be such officer before the Security so signed shall be
authenticated and delivered by or on behalf of the Trustee or disposed of by the
Company, such Securities nevertheless may be authenticated and delivered or
disposed of as though the Person who signed such Securities had not ceased to be
such officer of the Company; and any Security may be signed on behalf of the
Company by such Persons as, at the actual date of the original execution of such
Security, shall be the proper officers of the Company, although at the date of
the original execution and delivery of this Indenture, or at the date of such
Security, any such Person was not such an officer.

        Section 3.5     Certificate of Authentication.

        No Security shall be entitled to the benefits of this Indenture or be
valid or obligatory for any purpose, unless there appears on such Security a
certificate of authentication substantially in the form hereinbefore recited,
executed by or on behalf of the Trustee by manual signature. Such certificate by
or on behalf of the Trustee upon any Security executed by the Company shall be
conclusive evidence that the Security so authenticated has been duly
authenticated and delivered hereunder and that the Holder is entitled to the
benefits of this Indenture.

        Section 3.6     Registration, Registration of Transfer and Exchange.

        Subject to the conditions set forth below (and subject, with respect to
Global Securities, to Section 2.4), Securities of any series may be exchanged
for a like aggregate principal amount of Securities of the same series and
having the same terms but in other authorized denominations. Securities to be
exchanged shall be surrendered at the offices or agencies to be maintained for
such purposes as provided in Section 4.2, and the Company shall execute and the
Trustee or any Authenticating Agent shall authenticate and make available for
delivery in exchange therefor the Security or Securities which the Holder making
the exchange shall be entitled to receive.

                The Company shall keep or cause to be kept, at one of said
offices or agencies maintained pursuant to Section 4.2, a register for each
series of Securities issued hereunder (hereinafter collectively referred to as
the "Securities Register") in which, subject to such reasonable regulations as
it may prescribe, the Company shall, subject to the provisions of Section 2.4,
provide for the registration of Securities of such series and shall register the
transfer of Securities of such series as in this Article provided. The
Securities Register shall be in written form or in any other form capable of
being converted into written form within a reasonable time. The Trustee is
hereby appointed as the initial "Securities Registrar" for the purpose of
registering Securities and registering transfers of Securities as herein
provided. Subject to the provisions of Section 2.4, upon surrender for
registration of transfer of any Security of any series at any such office or
agency, the Company shall execute and the Trustee

                                      -20-

<PAGE>

or any Authenticating Agent shall authenticate and make available for delivery
in the name of transferee or transferees a new Security or Securities of the
same series for an equal aggregate principal amount.

                The Company shall have the right to remove and replace from time
to time the Security Registrar for any series of Securities; provided that no
such removal or replacement shall be effective until a successor Security
Registrar with respect to such series of Securities shall have been appointed by
the Company and shall have accepted such appointment by the Company. In the
event that the Trustee shall not be or shall cease to be Security Registrar with
respect to a series of Securities, it shall have the right to examine the
Security Register for such series at all reasonable times. There shall be only
one Security Register for each series of Securities.

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

                Each Security issued upon registration of transfer or exchange
of Securities pursuant to this Section shall be the valid obligation of the
Company, evidencing the same indebtedness and entitled to the same benefits
under this Indenture as the Security or Securities surrendered upon registration
of such transfer or exchange.

                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 3.10, Section 10.6 or Section 15.3 not
involving any transfer.

                The Company shall not be required (a) to issue, exchange or
register the transfer of any 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 such series and ending at the close of business on
the day of such mailing, or (b) to exchange or register the transfer of any
Securities selected, called or being called for redemption except, in the case
of any Security to be redeemed in part, the portion thereof not to be redeemed.

        Section 3.7     Mutilated, Destroyed, Lost and Stolen Securities.

        In case any temporary or definitive Security shall become mutilated
(whether by defacement or otherwise) or be destroyed, lost or stolen, and in the
absence of notice to the Company or the Trustee that such Security has been
acquired by a bona fide purchaser, the Company shall, except as otherwise
provided in this Section, execute, and upon a Company Request, the Trustee shall
authenticate and make available for delivery, a new Security of the same series,
tenor and principal amount, bearing a number, letter or other distinguishing
symbol

                                      -21-

not contemporaneously outstanding, in exchange and substitution for the
mutilated Security, or in lieu of and in substitution for the Security so
destroyed, lost or stolen. In every case the applicant for a substituted
Security shall furnish to the Company and to the Trustee and any agent of the
Company or the Trustee such security or indemnity as may be required by them to
save each of them harmless, and, in every case of destruction, loss or theft,
the applicant shall also furnish to the Company and the Trustee and any agent of
the Company or the Trustee evidence to their satisfaction of the destruction,
loss or theft of such Security and of the ownership thereof.

                Upon the issuance of any substitute 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 or any Authenticating
Agent) connected therewith.

                In case any Security which has matured or is about to mature or
has been called for redemption in full shall become mutilated or be destroyed,
lost or stolen, the Company may, instead of issuing a substitute Security, pay
or authorize the payment of the same (without surrender thereof except in the
case of a mutilated Security). In every case, the applicant for such payment
shall furnish to the Company and to the Trustee and any agent of the Company or
the Trustee such security or indemnity as any of them may require to save each
of them harmless, and, in every case of destruction, loss or theft, the
applicant shall also furnish to the Company and the Trustee and any agent of the
Company or the Trustee evidence to their satisfaction of the destruction, loss
or theft of such Security and of the ownership thereof.

                Every substitute Security of any series issued pursuant to the
provisions of this Section by virtue of the fact that any such Security is
destroyed, lost or stolen shall constitute an additional contractual obligation
of the Company, 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
(but shall be subject to all the limitations of rights set forth in) this
Indenture equally and proportionately with any and all other Securities of such
series duly authenticated and delivered hereunder. All Securities shall be held
and owned upon the express condition that, to the extent permitted by law, the
foregoing provisions of this Section are exclusive with respect to the
replacement or payment of mutilated (whether by defacement or otherwise) or
destroyed, lost or stolen Securities and shall preclude any and all other rights
or remedies notwithstanding any law or statute existing or hereafter enacted to
the contrary with respect to the replacement or payment of negotiable
instruments or other securities without their surrender.

        Section 3.8     Payment of Interest and Certain Additional Amounts;
Interest Rights and Certain Additional Amounts Preserved.

        The Holder of any Securities at the close of business on the Regular
Record Date with respect to any Interest Payment Date shall be entitled to
receive the interest, if any, and any Additional Amounts payable on such
Interest Payment Date notwithstanding the cancellation of such Securities upon
any registration of transfer or exchange subsequent to the Regular Record Date
and prior to such Interest Payment Date, and, if provided for in the Board
Resolution or

                                      -22-

<PAGE>

supplemental indenture pursuant to Section 3.1, in the case of a Security issued
between a Regular Record Date and the initial Interest Payment Date relating to
such Regular Record Date, interest for the period beginning on the date of issue
and ending on such initial Interest Payment Date shall be paid to the Person to
whom such Security shall have been originally issued. Except as otherwise
specified as contemplated by Section 3.1, for Securities of a particular series
the term "Regular Record Date" as used in this Section with respect to any
Interest Payment Date shall mean the close of business on the last day of the
calendar month preceding such Interest Payment Date if such Interest Payment
Date is the fifteenth day of a calendar month and shall mean the close of
business on the fifteenth day of the calendar month preceding such Interest
Payment Date if such Interest Payment Date is the first day of a calendar month,
whether or not such day shall be a Business Day. At the option of the Company,
payment of interest on any Security may be made by check mailed to the address
of the Person entitled thereto (which shall be the Depository in the case of
Global Securities) as such address shall appear in the Securities Register.

                If and to the extent the Company shall default in the payment of
the interest due or any Additional Amounts on such Interest Payment Date in
respect of any Securities, such defaulted interest shall be paid by the Company
at its election in each case, as provided in clause (a) or (b) below:

        (a)     The Company may make payment of any defaulted interest to the
Holder of Securities at the close of business on a Special Record Date
established by notice given by mail, by or on behalf of the Company, to such
Holder not less than 15 days preceding such Special Record Date, such Special
Record Date to be not less than 10 days preceding the date for payment of such
defaulted interest.

        (b)     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 the Securities of such series
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 3.9     Cancellation of Securities; Destruction Thereof.

        All Securities surrendered for payment, redemption, registration of
transfer or exchange, or for credit against any payment in respect of a sinking
or analogous fund, shall, if surrendered to the Company or any Paying Agent or
any Securities Registrar, be delivered to the Trustee for cancellation or, if
surrendered to the Trustee, shall be cancelled by it, and no Securities shall be
issued in lieu thereof except as expressly permitted by any of the provisions of
this Indenture.

                                      -23-

<PAGE>

All cancelled Securities held by the Trustee shall be disposed of by the Trustee
in accordance with its normal operating procedures, unless by a company order
the Company directs their return to it. If the Company shall acquire any of the
Securities, such acquisition shall not operate as a redemption or satisfaction
of the indebtedness represented by such Securities unless and until the same are
delivered to the Trustee for cancellation.

        Section 3.10    Temporary Securities.

        Pending the preparation by the Company of definitive Securities of any
series, the Company may execute and the Trustee shall authenticate and make
available for delivery in the manner provided in Section 3.3, temporary
Securities for such series (printed, lithographed, typewritten or otherwise
reproduced, in each case in form satisfactory to the Trustee). Temporary
Securities of any series shall be issuable in any authorized denomination, and
substantially in the form of the definitive Securities of such series in lieu of
which they are issued but with such omissions, insertions and variations as may
be appropriate for temporary securities, all as may be determined by the Company
with the concurrence of the Trustee. Temporary Securities may contain such
reference to any provisions of this Indenture as may be appropriate. Every
temporary Security shall be executed by the Company and be authenticated by the
Trustee upon the same conditions and in substantially the same manner, and with
like effect, as the definitive Securities. Without unreasonable delay the
Company shall execute and shall furnish definitive Securities of such series and
thereupon temporary Securities of such series may be surrendered in exchange
therefor without charge at the Corporate Trust Office of the Trustee, and the
Trustee shall authenticate and make available for delivery in exchange for such
temporary Securities an equal aggregate principal amount of definitive
Securities of the same series. Such exchange shall be made by the Company at its
own expense and without any charge therefor except that in case of any such
exchange involving any registration of transfer the Company may require payment
of a sum sufficient to cover any tax or other governmental charge that may be
imposed in relation thereto. 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 authenticated and delivered
hereunder.

        Section 3.11    Computation of Interest.

        Except as otherwise specified as contemplated by Section 3.1 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 3.12    CUSIP Numbers.

        The Company in issuing the Securities may use "CUSIP" numbers (if then
generally in use), and, if so, the Trustee shall use "CUSIP" numbers in notices
of redemption as a convenience to Holders as set-forth in Section 15.2.

                            COVENANTS OF THE COMPANY

<PAGE>

        The Company covenants and agrees for the benefit of each series of
Securities (except to the extent that any series of Securities is excluded from
the benefits of any of such covenants pursuant to Section 3.1(o)) that on and
after the date of original execution of this Indenture and so long as any of the
Securities of such series remain Outstanding:

        Section 4.1     Payment of Securities.

        The Company will duly and punctually pay or cause to be paid the
principal of any premium and interest on, and any Additional Amounts with
respect to the Securities of such series at the place or places, at the
respective times and in the manner provided in such Securities and in the
Indenture.

        Section 4.2     Offices or Agency.

        So long as any of the Securities remain Outstanding, the Company will
maintain in the Borough of Manhattan, The City of New York, New York, an office
or agency where such Securities may be presented or surrendered for payment,
where such Securities may be surrendered for registration of transfer or
exchange and where notices and demands to or upon the Company in respect of such
Securities and this Indenture may be served, which office or agency shall
initially be the Corporate Trust Office of the Trustee or, if the Corporate
Trust Office of the Trustee is not located in the Borough of Manhattan, The City
of New York, such office or agency shall be the principal corporate trust office
of the Authenticating Agent designated pursuant to Section 7.14 hereof. The
Company will give prompt written notice to the Trustee of any change in the
location of any such office or agency. If at any time the Company shall fail to
maintain such required office or agency or shall fail to furnish the Trustee
with the required information with respect thereto, presentations, surrenders,
notices and demands in respect of Securities may be made or served at the
Corporate Trust Office of the Trustee and the corporate trust office of any
Authenticating Agent appointed hereunder; and the Company hereby appoints the
Trustee and any Authenticating Agent appointed hereunder its agents 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 (in or outside The City of New York) where the
Securities of one or more series, or any Tranche thereof may be presented or
surrendered for any or all of such purposes, and may from time to time rescind
such designation; provided, however, that no such designation or rescission
shall in any manner relieve the Company of its obligation to maintain for such
purposes an office or agency in the Borough of Manhattan, The City of New York.
The Company will promptly notify the Trustee of any such designation or
rescission thereof.

                Unless otherwise specified with respect to any Securities
pursuant to Section 3.1, if and so long as the Securities of any series (i) are
denominated in a Foreign Currency or (ii) may be payable in a Foreign Currency,
or so long as it is required under any other provision of this Indenture, then
the Company will maintain with respect to each such series of Securities, or as
so required, at least one exchange rate agent.

        Section 4.3     Money for Securities Payments to Be Held in Trust.

        If the Company shall at any time act as its own Paying Agent with
respect to any series of Securities, it shall, on or before each due date of the
principal of, any premium or interest on or Additional Amounts with respect to
any of the Securities of such series, segregate and hold in trust for the
benefit of the Persons entitled thereto a sum in the currency or currencies,
currency unit or units or composite currency or currencies in which the
Securities of such series are payable (except as otherwise specified pursuant to
Section 3.1 for the Securities of such series) sufficient to pay the principal
or any premium, interest or Additional Amounts so becoming due until such sums
shall be paid to such Persons or otherwise disposed of as herein provided, and
shall promptly notify the Trustee in writing of its action or failure so to act.

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

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

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

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

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

                The Company 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 terms as those upon which such sums were held by the Company or
such Paying Agent; and, upon such payment by any Paying Agent to the Trustee,
such Paying Agent shall be released from all further liability with respect to
such sums.

                                      -26-

<PAGE>

                Anything in this Section to the contrary notwithstanding, the
agreement to hold sums in trust as provided in this Section is subject to the
provisions of Section 12.3, Section 12.4 and Section 12.5.

        Section 4.4     Additional Amounts.

        All payments of principal of and premium, if any, interest and any other
amounts on, or in respect of, the Securities of any series shall be made without
withholding or deduction at source for, or on account of, any present or future
taxes, fees, duties, assessments or governmental charges of whatever nature
imposed or levied by or on behalf of Bermuda or any other jurisdiction in which
the Company is organized (each, a "taxing jurisdiction") or any political
subdivision or taxing authority thereof or therein, unless such taxes, fees,
duties, assessments or governmental charges are required to be withheld or
deducted by (i) the laws (or any regulations or ruling promulgated thereunder)
of a taxing jurisdiction or any political subdivision or taxing authority
thereof or therein or (ii) an official position regarding the application,
administration, interpretation or enforcement of any such laws, regulations or
rulings (including, without limitation, a holding by a court of competent
jurisdiction or by a taxing authority in a taxing jurisdiction or any political
subdivision thereof).

                If a withholding or deduction at source is required, the Company
shall, subject to certain limitations and exceptions set forth below, pay to the
Holder of any such Security such Additional Amounts as may be necessary so that
every net payment of principal, premium, if any, interest or any other amount
made to such Holder, after such withholding or deduction, shall not be less than
the amount provided for in such Security and this Indenture to be then due and
payable; provided, however, that the Company shall not be required to make
payment of such Additional Amounts for or on account of:

        (a)     any tax, fee, duty, assessment or governmental charge of
whatever nature which would not have been imposed but for the fact that such
Holder: (A) was a resident, domiciliary or national of, or engaged in business
or maintained a permanent establishment or was physically present in, the
relevant taxing jurisdiction or any political subdivision thereof or otherwise
had some connection with the relevant taxing jurisdiction other than by reason
of the mere ownership of, or receipt of payment under, such Security; (B)
presented such Security, where presentation is required, for payment in the
relevant taxing jurisdiction or any political subdivision thereof, unless such
Security could not have been presented for payment elsewhere; or (C) presented
such Security, where presentation is required, more than thirty (30) days after
the date on which the payment in respect of such Security first became due and
payable or provided for, whichever is later, except to the extent that the
Holder would have been entitled to such Additional Amounts if it had presented
such Security for payment on any day within such period of thirty (30) days;

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

                                      -27-

<PAGE>

        (c)     any tax, assessment or other governmental charge that is imposed
or withheld by reason of the failure by the Holder or the beneficial owner of
such Security to comply with any reasonable request by the Company addressed to
the Holder within 90 days of such request (A) to provide information concerning
the nationality, residence or identity of the Holder or such beneficial owner or
(B) to make any declaration or other similar claim or satisfy any information or
reporting requirement, which, in the case of (A) or (B), is required or imposed
by statute, treaty, regulation or administrative practice of the relevant taxing
jurisdiction or any political subdivision thereof as a precondition to exemption
from all or part of such tax, assessment or other governmental charge;

        (d)     any withholding or deduction required to be made pursuant to any
EU Directive on the taxation of savings implementing the conclusions of the
ECOFIN Council meetings of 26-27 November 2000, 3 June 2003 or any law
implementing or complying with, or introduced in order to confirm to, such EU
Directive; or

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

nor shall Additional Amounts be paid with respect to any payment of the
principal of, or premium, if any, interest or any other amounts on, any such
Security to any Holder who is a fiduciary or partnership or other than the sole
beneficial owner of such Security to the extent such payment would be required
by the laws of the relevant taxing jurisdiction (or any political subdivision or
relevant taxing authority thereof or therein) to be included in the income for
tax purposes of a beneficiary or partner or settlor with respect to such
fiduciary or a member of such partnership or a beneficial owner who would not
have been entitled to such Additional Amounts had it been the Holder of the
Security.

                Whenever in this Indenture there is mentioned, in any context,
the payment of the principal of or any premium, interest or any other amounts
on, or in respect of, any Security of any series or the net proceeds received on
the sale or exchange of any Security of any series, such mention shall be deemed
to include mention of the payment of Additional Amounts provided by the terms of
such series established hereby or pursuant hereto to the extent that, in such
context, Additional Amounts are, were or would be payable in respect thereof
pursuant to such terms, and express mention of the payment of Additional Amounts
(if applicable) in any provision hereof shall not be construed as excluding the
payment of Additional Amounts in those provisions hereof where such express
mention is not made.

                Except as otherwise provided in or pursuant to this Indenture or
the related Board Resolution of the applicable series, at least 10 days prior to
the first Interest Payment Date with respect to a series of Securities (or if
the Securities of such series shall not bear interest prior to Maturity, the
first day on which a payment of principal is made), and at least 10 days prior
to each date of payment of principal or interest if there has been any change
with respect to the matters set forth in the below-mentioned Officer's
Certificate, the Company shall furnish to the Trustee and the principal Paying
Agent or Paying Agents, if other than the Trustee, an Officer's Certificate
instructing the Trustee and such Paying Agent or Paying Agents whether such
payment of principal of and premium, if any, interest or any other

                                      -28-

<PAGE>

amounts on the Securities of such series shall be made to Holders of Securities
of such series without withholding for or on account of any tax, fee, duty,
assessment or other governmental charge described in this Section 4.4. If any
such withholding shall be required, then such Officer's Certificate shall
specify by taxing jurisdiction the amount, if any, required to be withheld on
such payments to such Holders of Securities and the Company agrees to pay to the
Trustee or such Paying Agent the Additional Amounts required by this Section
4.4. The Company covenants to indemnify the Trustee and any Paying Agent for,
and to hold them harmless against, any loss, liability or expense reasonably
incurred without negligence or bad faith on their part arising out of or in
connection with actions taken or omitted by any of them in reliance on any
Officer's Certificate furnished pursuant to this Section 4.4.

        Section 4.5     Redemption for Tax Purposes.

        The Company may redeem the Securities at its option, in whole but not in
part, at a Redemption Price equal to 100% of the principal amount, together with
accrued and unpaid interest and Additional Amounts, if any, to the date fixed
for redemption, at any time it receives an opinion of counsel that as a result
of (i) any change in or amendment to the laws or treaties (or any regulations or
rulings promulgated under these laws or treaties) of Bermuda or any taxing
jurisdiction (or of any political subdivision or taxation authority affecting
taxation) or any change in the application or official interpretation of such
laws, regulations or rulings, or (ii) any action taken by a taxing authority of
Bermuda or any taxing jurisdiction (or any political subdivision or taxing
authority affecting taxation) which action is generally applied or is taken with
respect to the Company, or (iii) a decision rendered by a court of competent
jurisdiction in Bermuda or any taxing jurisdiction (or any political
subdivision) whether or not such decision was rendered with respect to the
Company, there is a substantial probability that the Company will be required as
of the next Interest Payment Date to pay Additional Amounts with respect to the
Securities as provided in Section 4.4 and such requirements cannot be avoided by
the use of reasonable measures (consistent with practices and interpretations
generally followed or in effect at the time such measures could be taken) then
available. If the Company elects to redeem the Securities under this provision
it will give written notice of such election to the Trustee. If the Company
elects to redeem the Securities under this provision it will also mail a notice
of redemption at least 30 days but no more than 60 days before the Redemption
Date to each Holder of the Securities to be redeemed. Unless the Company
defaults in the payment of the Redemption Price, on and after the Redemption
Date, interest will cease to accrue on the Securities or portions thereof called
for redemption. Any such redemption will be subject to ARTICLE 15 hereof.

        Section 4.6     Corporate Existence.

        Subject to ARTICLE 11, the Company shall do or cause to be done all
things necessary to preserve and keep in full force and effect its legal
existence and rights (charter and statutory) and franchises; provided, however,
that the foregoing shall not obligate the Company to preserve any such right or
franchise if the Company shall determine that the preservation thereof is no
longer desirable in the conduct of its business and that the loss thereof is not
disadvantageous in any material respect to any Holder.

        Section 4.7     Waiver of Certain Covenants.

        The Company may omit in any particular instance to comply with any term,
provision or condition set forth in Section 4.8 with respect to the Securities
of any series if before the time for such compliance the Holders of at least a
majority in principal amount of the Outstanding Securities of such series, by
Act of such Holders, either shall waive such compliance in such instance or
generally shall have waived compliance with such term, provision or condition,
but no such waiver shall extend to or affect such term, provision or condition
except to the extent so expressly waived, and, until such waiver shall become
effective, the obligations of the Company and the duties of the Trustee in
respect of any such term, provision or condition shall remain in full force and
effect.

        Section 4.8     Certificates to Trustee.

        The Company will, within 120 days after the end of each fiscal year,
file with the Trustee an Officer's Certificate complying with the provisions of
the second paragraph of Section 14.6, covering the period from the date of
original execution of this Indenture to December 31, 2003 in the case of the
first such certificate, and covering the preceding calendar year in the case of
each subsequent certificate, and stating whether or not, to the knowledge of
each of the signers, one of whom shall be principal executive officer, principal
financial officer or principal accounting officer, the Company has complied with
the conditions and covenants on its part contained in this Indenture, and, if
the signers, to the best of their knowledge, know of any event which is, or
after notice or lapse of time or both would become, a default by the Company in
the performance, observance or fulfillment of any such condition or covenant,
specifying each such default and the nature thereof. For the purpose of this
Section, compliance shall be determined without regard to any grace period or
requirement of notice provided pursuant to the terms of this Indenture.

        The Company shall deliver to the Trustee, within five days after the
occurrence thereof, written notice of any Event of Default or any event which
after notice or lapse of time or both would become an Event of Default pursuant
to clause (c) of Section 6.1.

        Section 4.9     Calculation of Original Issue Discount.

        The Company shall file with the Trustee promptly at the end of each
calendar year (i) a written notice specifying the amount of original issue
discount (including daily rates and accrual periods) accrued on any Outstanding
Original Issue Discount Securities as of the end of such year and (ii) such
other specific information relating to such original issue discount as may then
be relevant under the Code, as amended from time to time.

        The Company covenants and agrees that it will furnish or cause to be
furnished to the Trustee a list in such form as the Trustee may reasonably
require of the names and addresses of the Holders of the Securities of each
series semiannually and not later than June 30 and December 31 in each year, and

than 15 days prior to the date such information is so furnished; provided that,
if and so long as the Trustee shall be the Securities Registrar for such series,
such list shall not be required to be furnished.

        Section 5.2     Preservation and Disclosure of Securityholder Lists.

        (a)     The Trustee shall preserve, in as current a form as is
reasonably practicable, all information received by it pursuant to Section 5.1
and similar information received by it in any other capacity under this
Indenture and afford Holders access to the information preserved by it, all to
such extent, if any, and in such manner as shall be required by the Trust
Indenture Act.

        (b)     Each and every Holder of Securities, by receiving and holding
the same, agrees with the Company and the Trustee that neither the Company nor
the Trustee nor any Paying Agent shall be held accountable by reason of the
disclosure of any such information as to the names and addresses of the Holders
of Securities in accordance with the provisions of Section 5.2(a), regardless of
the source from which such information was derived, and that the Trustee shall
not be held accountable by reason of mailing any material pursuant to a request
made under Section 5.2(a). In case three or more Holders of Securities of any
series (for purposes of this Section, "applicants") apply in writing to the
Trustee and furnish to 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 other Holders of Securities of a particular series (in which
case the applicants must all hold Securities of such series) or with Holders of
all Securities with respect to their rights under this Indenture or under such
Securities and such application 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 to such applicants access to the information
        preserved at the time by the Trustee in accordance with the provision of
        subsection (a) of this Section 5.2, or

                (ii)    inform such applicant as to the approximate number of
        Holders of Securities of such series or all Securities, as the case may
        be, whose names and addresses appear in the information preserved at the
        time by the Trustee, in accordance

                                      -31-

<PAGE>

        with the provisions of subsection (a) of this Section 5.2, and as to the
        approximate cost of mailing to such Securityholders the form of proxy or
        other communication, if any, specified in such application. If the
        Trustee shall elect not to afford to such applicants access to such
        information, the Trustee shall, upon the written request of such
        applicants, mail to each Securityholder of such series or all
        Securities, as the case may be, whose name and address appear in the
        information preserved at the time by the Trustee in accordance with the
        provisions of subsection (a) of this Section 5.2, a copy of the form of
        proxy or other communication which is specified in such request, with
        reasonable promptness after a tender to the Trustee of the material to
        be mailed and of payment, or provision for the payment, of the
        reasonable expenses of a mailing, unless within five days after such
        tender, the Trustee shall mail to such applicants and file with the
        Commission together with a copy of the material to be mailed, a written
        statement to the effect that, in the opinion of the Trustee, such
        mailing would be contrary to the best interest of the Holders of
        Securities of such series or all Securities, as the case may be, or
        could 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 such 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 Securityholders 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.

        Section 5.3     Reports by the Company.

        The Company covenants:

        (a)     to file with the Trustee, within 15 days after the Company is
required to file the same with the Commission, copies of the annual reports and
of the information, documents and other reports (or copies of such portions of
any of the foregoing as the Commission may from time to time by rules and
regulations prescribe) which the Company may be required to file with the
Commission pursuant to Section 13 or Section 15(d) of the Securities Exchange
Act of 1934; or, if the Company is not required to file information, documents
or reports pursuant to either of such Sections, then to file with the Trustee
and the Commission, in accordance with rules and regulations prescribed from
time to time by the Commission, such of the supplementary and periodic
information, documents and reports which may be required pursuant to Section 13
of the Securities Exchange Act of 1934 in respect of a security listed and
registered on a national securities exchange as may be prescribed from time to
time in such rules and regulations;

        (b)     to file with the Trustee and the Commission, in accordance with
rules and regulations prescribed from time to time by the Commission, such
additional information, documents and reports with respect to compliance by the
Company with the conditions and

                                      -32-

<PAGE>

covenants provided for in this Indenture as may be required from time to time by
such rules and regulations; and

        (c)     to transmit by mail to the Holders of Securities in the manner
and to the extent provided in Section 5.4 within 30 days after the filing
thereof with the Trustee, such summaries of any information, documents and
reports required to be filed by the Company pursuant to subsections (a) and (b)
of this Section as may be required to be transmitted to such Holders by rules
and regulations prescribed from time to time by the Commission.

        The delivery of such reports, information and documents to the Trustee
pursuant to this Section 5.3 is for informational purposes only and the
Trustee's receipt of such shall not constitute constructive notice of any
information contained therein or determinable from information contained
therein, including the Company's compliance with any of its covenants hereunder
(as to which the Trustee is entitled to rely exclusively on Officer's
Certificates) other than with respect to Section 7.2.

        Section 5.4     Reports by the Trustee.

        (a)     Within 60 days after May 15 in each year following the date of
original execution of this Indenture, so long as any Securities are Outstanding
hereunder, the Trustee shall transmit by mail (with a copy to the Company) to
the Securityholders of such series in the manner and to extent provided in Trust
Indenture Act Section 313(c), a brief report, as provided by the Trust Indenture
Act Sections 313(a) and (b).

        (b)     A copy of each such report shall, at the time of such
transmission to the Securityholders of any series, be furnished to the Company
and be filed by the Trustee with each stock exchange upon which the Securities
of such series are listed and also with the Commission. The Company agrees to
notify the Trustee promptly when and as the Securities of any series become
admitted to trading on any national securities exchange.

Waiver of Default.

        "Event of Default", with respect to the Securities of any series,
wherever used herein, means each one of the following events which shall have
occurred and be continuing (whatever the reason for such Event of Default and
whether it shall be voluntary or involuntary or be effected by operation of law
or pursuant to any judgment, decree or order of any court or any order, rule or
regulation of any administrative or governmental body), unless it is either
inapplicable to a particular series or it is specifically deleted or modified in
the applicable resolution of the Board of Directors or in the supplemental

of such series, or any Additional Amounts payable with respect thereto, as and
when the same shall become due and payable, and continuance of such default for
a period of 30 days and the time for payment of such interest or Additional
Amounts has not been extended; provided, however that if the Company is
permitted by the terms of the Securities of the applicable series to defer the
payment in question, the date on which such payment is due and payable shall be
the date on which the Company is required to make payment following such
deferral, if such deferral has been elected pursuant to the terms of the
Securities of that series; or

        (b)     default in the payment of the principal of or premium, if any,
on any of the Securities of such series as, or any Additional Amounts payable
with respect thereto, and when the same shall become due and payable at
Maturity, and the time for payment of such principal (or premium, if any), or
any Additional Amounts payable with respect thereto, has not been extended;
provided, however, that if the Company is permitted by the terms of the
Securities of the applicable series to defer the payment in question, the date
on which such payment is due and payable shall be the date on which the Company
is required to make payment following such deferral, if such deferral has been
elected pursuant to the terms of the Securities of that series; or

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

        (d)     default in the payment at Maturity of Indebtedness of the
Company in excess of $50,000,000 or if any event of default as defined in any
mortgage, indenture or instrument under which there may be issued, or by which
there may be secured or evidenced, any Indebtedness of the Company (other than
Indebtedness which is non-recourse to the Company) shall happen and shall result
in the acceleration of more than $50,000,000 in principal amount of such
Indebtedness (after giving effect to any applicable grace period) and such
default shall not be cured or waived or such acceleration shall not be rescinded
or annulled within a period of 30 days after there shall have been given, by
registered or certified mail, to the Company by the Trustee or to the Company
and the Trustee by the Holders of at least 25% in principal amount of the
Outstanding Securities of such series, a written notice specifying such default
or event of default and requiring the Company to cause such default to be cured
or waived or to cause such acceleration to be rescinded or annulled or to cause
such Indebtedness to be discharged and stating that such notice is a "Notice of
Default" hereunder; or

                                      -34-

        (e)     the Company shall fail within 60 days to pay, bond or otherwise
discharge any uninsured judgment or court order for the payment of money in
excess of $50,000,000, which is not stayed on appeal or is not otherwise being
appropriately contested in good faith; or

        (f)     a court having jurisdiction in the premises shall enter a decree
or order for relief in respect of the Company in an involuntary case under any
applicable bankruptcy, insolvency or other similar law now or hereafter in
effect, or, under any such law, (i) appointing a receiver, liquidator, assignee,
custodian, trustee or sequestrator (or similar official) of the Company or for
any substantial part of its property or (ii) ordering the winding up or
liquidation of its affairs, and such decree or order shall remain unstayed and

under any such law, (i) consent to the entry of an order for relief in an
involuntary case under any such law, (ii) consent to the appointment or taking
possession by a receiver, liquidator, assignee, custodian, trustee or
sequestrator (or similar official) of the Company or for any substantial part of
its property, or (iii) make any general assignment for the benefit of creditors;
or

        (h)     default in the performance or breach of the conditions of
Section 11.1 and Section 11.2, and the continuation of such violation for 60
days after there has been given, by registered or certified mail, to the Company
by the Trustee or to the Company and the Trustee by the Holders of at least 25%
in principal amount of the Outstanding Securities of such series, a written
notice specifying such failure to comply and requiring it to be remedied and
stating that such notice is a "Notice of Default"; or

        (i)     any other Event of Default established by or pursuant to a
resolution of the Board of Directors or one or more indentures supplemental
hereto as applicable to the Securities of such series.

        If an Event of Default described in clause (a), (b), (c), (d), (e), (h)
or (i) above occurs and is continuing with respect to Securities of any series
at the time Outstanding, the Trustee or the Holders of not less than 25% in
aggregate principal amount of the Securities of such series then Outstanding, by
notice in writing to the Company (and to the Trustee if given by
Securityholders), may declare the entire principal (or, if the Securities of
such series are Original Issue Discount Securities, such portion of the
principal as may be specified in the terms of such series) of all Securities of
such series and the interest accrued thereon, if any, to be due and payable
immediately, and upon any such declaration the same shall become immediately due
and payable.

                If any Event of Default described in clause (f) or (g) above
occurs and is continuing, all unpaid principal of the Securities then
Outstanding of that series and the interest accrued thereon, if any, shall ipso
facto become and be immediately due and payable without declaration,
presentment, demand or notice of any kind by the Trustee or any Holder of
Securities of that series.

                                      -35-

<PAGE>

                The foregoing provisions, however, are subject to the condition
that if, at any time after a declaration of acceleration with respect to the
Securities of any series has been made and before any judgment or decree for the
payment of the moneys due shall have been obtained or entered as hereinafter
provided, the Company shall pay or shall deposit with the Trustee a sum
sufficient to pay all matured installments of interest, if any, and any
Additional Amounts with respect to all the Securities of such series (or upon
all the Securities, as the case may be) and the principal of (and premium, if
any, on) any and all Securities of such series (or of all the Securities, as the
case may be) which shall have become due otherwise than by acceleration (with
interest upon such principal and premium, if any, and, to the extent that
payment of such interest is enforceable under applicable law, on overdue
installments of interest or Additional Amounts, at the Overdue Rate applicable
to such series to the date of such payment or deposit) and all amounts payable
to the Trustee pursuant to the provisions of Section 7.6, and such amount as
shall be sufficient to cover reasonable compensation to the Trustee, its agents,
attorneys and counsel, and all other expenses and liabilities incurred, and all
advances made, by the Trustee except as a result of negligence or bad faith, and
if any and all Events of Default under the Indenture, other than the nonpayment
of the principal of and accrued interest on and any Additional Amounts with
respect to Securities of such series which shall have become due by
acceleration, shall have been cured, waived or otherwise remedied as provided
herein - then and in every such case the Holders of a majority in aggregate
principal amount of the Securities of such series (each series voting as a
separate class), or of all the Securities (voting as a single class), as the
case may be, then Outstanding, by written notice to the Company and to the
Trustee, may waive all defaults with respect to that series (or with respect to
all the Securities, as the case may be) and rescind and annul such acceleration
and its consequences, but no such waiver or rescission and annulment shall
extend to or shall affect any subsequent default or shall impair any right
consequent thereon.

                For all purposes under this Indenture, if a portion of the
principal of any Original Issue Discount Security shall have been accelerated
and declared or become due and payable pursuant to the provisions hereof, then,
from and after such acceleration, unless such acceleration has been rescinded
and annulled, the principal amount of such Original Issue Discount Security
shall be deemed, for all purposes hereunder, to be such portion of the principal
thereof as shall be due and payable as a result of such acceleration, and
payment of such portion of the principal thereof as shall be due and payable as
a result of such acceleration, together with interest, if any, thereon and all
other amounts owing thereunder, shall constitute payment in full of such
Original Issue Discount Security.

        Section 6.2     Collection of Indebtedness by Trustee; Trustee May Prove
Debt.

        The Company covenants that (a) in case default shall be made in the
payment of any installment of interest on or any Additional Amounts with respect
to any of the Securities of any series when such interest shall have become due
and payable, and such default shall have continued for a period of 30 days or
(b) in case default shall be made in the payment of all or any part of the
principal of or any premium, if any, on any Securities of any series or any
Additional Amounts with respect thereto when the same shall have become due and
payable, whether upon Stated Maturity of the Securities of such series or upon
any redemption or by

                                      -36-

<PAGE>

acceleration or otherwise, then upon demand of the Trustee for such series, the
Company will pay to the Trustee for the benefit of the Holder of any such
Security the whole amount that then shall have become due and payable on any
such Security for the principal, premium, if any, and interest, if any, with
interest upon the overdue principal and premium, if any, and, so far as payment
of the same is enforceable under applicable law, on overdue installments of
interest and Additional Amounts, at the Overdue Rate applicable to any such
Security; and, in addition thereto, such further amount as shall be sufficient
to cover the costs and expenses of collection, and any further amounts payable
to the Trustee, its agents and counsel pursuant to the provisions of Section
7.6.

                In case the Company shall fail forthwith to pay such amounts
upon such demand, the Trustee, in its own name and as trustee of an express
trust, shall be entitled and empowered to institute any action or proceedings at
law or in equity for the collection of the sums so due and unpaid, and may
prosecute any such action or proceedings to judgment or final decree, and may
enforce any such judgment or final decree against the Company or other obligor
upon such Securities and collect in the manner provided by law out of the
property of the Company or other obligor upon such Securities, wherever
situated, the moneys adjudged or decreed to be payable.

                The Trustee shall be entitled and empowered, either in its own
name as trustee of an express trust, or as attorney-in-fact for the Holders of
any of the Securities, or in both such capacities, to file such proof of debt,
amendment of proof of debt, claim, petition or other document as may be
necessary or advisable in order to have the claims of the Trustee and of the
Holders of Securities allowed in any equity receivership, insolvency,
bankruptcy, liquidation, readjustment, reorganization or other similar
proceedings, or any judicial proceedings, relative to the Company or any other
obligor on the Securities or its creditors or its property. The Trustee is
hereby irrevocably appointed (and the successive respective Holders of the
Securities, by taking and holding the same, shall be conclusively deemed to have
so appointed the Trustee) the true and lawful attorney-in-fact of the respective
Holders of the Securities, with authority to make or file in the respective
names of the Holders of the Securities any proof of debt, amendment of proof of
debt, claim, petition or other document in any such proceedings and to receive
payment of any sums becoming distributable on account thereof, and to execute
any other papers and documents and do and perform any and all acts and things
for and on behalf of such Holders of the Securities as may be necessary or
advisable in the opinion of the Trustee in order to have the respective claims
of the Holders of the Securities against the Company or any other obligor on the
Securities and/or its property allowed in any such proceedings, and to receive
payment of or on account of such claims; provided, however, that nothing herein
contained shall be deemed to authorize or empower the Trustee to consent to or
accept or adopt, on behalf of any Holder of Securities, any plan of
reorganization or readjustment of the Company or any other obligor on the
Securities or, by other action of any character in any such proceeding, to waive
or change in any way any right of any Holder of any Security, even though it may
otherwise be entitled so to do under any present or future law, all such power
or authorization being hereby expressly denied.

                                      -37-

<PAGE>

                All rights of action and of asserting claims under this
Indenture or under any of the Securities may be enforced by the Trustee without
the possession of any of the Securities or the production thereof in any trial
or other proceedings relative thereto, and any such action or proceedings
instituted by the Trustee shall be brought in its own name as trustee of an
express trust, and any recovery of judgment, subject to the payment of the
expenses, disbursements and compensation of the Trustee, each predecessor
Trustee and their respective agents and attorneys, shall be for the ratable
benefit of the holders of the Securities in respect of which such action was
taken.

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

        Section 6.3     Application of Proceeds.

        Any moneys collected by the Trustee pursuant to this Article in respect
of any series of the Securities, together with any other sums held by the
Trustee (as such) hereunder (other than sums held in trust for the benefit of
the Holders of particular Securities), shall be applied in the following order
at the date or dates fixed by the Trustee and, in case of the distribution of
such moneys on account of principal, or any premium, interest or Additional
Amounts, upon presentation (except in respect of Subdivision First below) of the
several Securities in respect of which moneys have been collected and stamping
(or otherwise noting) thereon the payment, or issuing Securities of such series
in reduced principal amounts in exchange for the presented Securities of like
series if only partially paid, or upon surrender thereof if fully paid:

                FIRST: To the payment of costs and expenses applicable to such
        series in respect of which moneys have been collected, including
        reasonable compensation to the Trustee and each predecessor Trustee and
        their respective agents and attorneys and of all expenses and
        liabilities incurred, and all advances made, by the Trustee and each
        predecessor Trustee except as a result of negligence or bad faith, and
        all other amounts due to the Trustee or any predecessor Trustee pursuant
        to Section 7.6;

                SECOND: In case the principal of the Securities of such series
        in respect of which moneys have been collected shall not have become and
        be then due and payable, to the payment of interest and any Additional
        Amounts on the Securities of such series in default in the order of the
        maturity of the installments of such interest, with interest (to the
        extent that such interest has been collected by the Trustee), so far as
        it may be enforceable under applicable law, upon the overdue
        installments of interest and any Additional Amounts at the Overdue Rate
        applicable to such series, such payments to be made ratably to the
        Persons entitled thereto, without discrimination or preference;

                THIRD: In case the principal of the Securities of such series in
        respect of which moneys have been collected shall have become and shall
        be then due and payable, to the

                                      -38-

<PAGE>

        payment of the whole amount then owing and unpaid upon all the
        Securities of such series for principal and premium, if any, and
        interest, if any, and any Additional Amounts, with interest upon the
        overdue principal and premium, if any, and (to the extent that such
        interest has been collected by the Trustee), so far as payment of the
        same is enforceable under applicable law, upon overdue installments of
        interest and any Additional Amounts, if any, at the Overdue Rate
        applicable to such series; and in case such moneys shall be insufficient
        to pay in full the whole amount so due and unpaid upon the Securities of
        such series, then to the payment of such principal, premium, if any, and
        interest, if any, and any Additional Amounts, without preference or
        priority of principal and premium, if any, over interest or any
        Additional Amounts, or of interest or any Additional Amounts, if any,
        over principal and premium, if any, or of any installment of interest
        over any other installment of interest, or of any Security of such
        series over any other Security of such series, ratably to the aggregate
        of such principal, premium, if any, and accrued and unpaid interest, if
        any; and

                FOURTH: To the payment of the remainder, if any, to the Company
        or as a court of competent jurisdiction may direct in writing.

        Section 6.4     Suits for Enforcement.

        In case an Event of Default with respect to Securities of any series has
occurred, has not been waived and is continuing, the Trustee may in its
discretion proceed to protect and enforce the rights vested in it by this
Indenture by such appropriate judicial proceedings as the Trustee shall deem
necessary to protect and enforce any of such rights, either at law or in equity
or in bankruptcy or otherwise, whether for the specific enforcement of any
covenant or agreement contained in this Indenture or in aid of the exercise of
any power granted in this Indenture or to enforce any other legal or equitable
right vested in the Trustee by this Indenture or by law.

        Section 6.5     Restoration of Rights on Abandonment of Proceedings.

        In case the Trustee or any Holder shall have proceeded to enforce any
right under this Indenture and such proceedings shall have been discontinued or
abandoned for any reason, or shall have been determined adversely to the Trustee
or such Holder, then and in every such case (subject to the binding effect of
any determination made in such proceedings) the Company and the Trustee and each
of the Holders shall be restored severally and respectively to their former
positions and rights hereunder, and (subject as aforesaid) all rights, remedies
and powers of the Company, the Trustee and the Holders shall continue as though
no such proceedings had been instituted.

        Section 6.6     Limitations on Suits by Securityholders.

        No Holder of any Security of any series shall have any right by virtue
or by availing of any provision of this Indenture to institute an action or

notice of an Event of Default and of the continuance thereof, as hereinbefore
provided, and unless also the Holders of not less than 25% in aggregate
principal amount of the Securities of such series then Outstanding shall have
made written request upon the Trustee to institute such action or proceeding in
its own name as Trustee hereunder and shall have offered to the Trustee such
reasonable indemnity as it may require against the costs, expenses and
liabilities to be incurred therein or thereby and the Trustee for 60 days after
its receipt of such notice, request and offer of indemnity shall have failed to
institute any such action or proceeding and no direction inconsistent with such
written request shall have been given to the Trustee pursuant to Section 6.9; it
being understood and intended, and being expressly covenanted by the taker and
Holder of every Security with every other taker and Holder of any Security and
with the Trustee, that no one or more Holders of Securities of any series shall
have any right in any manner whatever by virtue or by availing of any provision
of this Indenture to affect, disturb or prejudice the rights of any other Holder
of Securities, or to obtain or seek to obtain priority over or preference to any
other such Holder or to enforce any right under this Indenture, except in the
manner herein provided and for the equal, ratable and common benefit of all
Holders of Securities of such series. For the protection and enforcement of the
provisions of this Section, each and every Holder of Securities of any series
and the Trustee shall be entitled to such relief as can be given either at law
or in equity.

        Section 6.7     Unconditional Right of Securityholders to Institute
Certain Suits.

        Nothing contained in this Indenture or in the Securities of any series
shall affect or impair the obligation of the Company, which is unconditional and
absolute, to pay the principal of, and premium, if any, and interest, if any,
on, and any Additional Amounts with respect to, the Securities of such series at
the respective places, at the respective times, at the respective rates, in the
respective amounts and in the coin or currency therein and herein prescribed, or
affect or impair the right of action, which is also absolute and unconditional,
of any Holder of any Security to institute suit to enforce such payment at the
respective due dates expressed in such Security, or upon redemption, by
declaration, repayment or otherwise as herein provided without reference to, or
the consent of, the Trustee or the Holder of any other Security, unless such
Holder consents thereto or unless and to the extent that the institution or
prosecution.

        Section 6.8     Powers and Remedies Cumulative; Delay or Omission Not
Waiver of Default.

        Except as provided in Section 6.6, no right or remedy herein conferred
upon or reserved to the Trustee or to the Holder of any Security is intended to
be exclusive of any other right or remedy, and every right and remedy shall, to
the extent permitted by law, be cumulative and in addition to every other right
and remedy given hereunder or now or hereafter existing at law or in equity or
otherwise. The assertion or employment of any right or remedy hereunder, or
otherwise, shall not prevent the concurrent assertion or employment of any other
appropriate right or remedy.

<PAGE>

        No delay or omission of the Trustee or of any Holder of any Security of
any series to exercise any right or power accruing upon any Event of Default
occurring and continuing as aforesaid shall impair any such right or power or
shall be construed to be a waiver of any such Event of Default or an
acquiescence therein; and, subject to Section 6.6, every power and remedy given
by this Indenture or by law to the Trustee or to the Holder of any Security may
be exercised from time to time, and as often as shall be deemed expedient, by
the Trustee or by the Holder of such Security.

        Section 6.9     Control by Holders of Securities.

        The Holders of a majority in aggregate principal amount of the
Securities of each series affected (with each series voting as a separate class)
at the time Outstanding 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 by this Indenture; provided that such direction shall
not be otherwise than in accordance with law and the provisions of this
Indenture, and provided, further, that (subject to the provisions of Section
7.1) the Trustee shall have the right to decline to follow any such direction if
the Trustee, being advised by counsel, shall determine that the action or
proceeding so directed may not lawfully be taken or if the Trustee in good faith
by a trust committee of directors or Responsible Officers of the Trustee shall
determine that the action or proceedings so directed would expose the Trustee to
personal liability or if the Trustee in good faith shall so determine that the
actions or forebearances specified in or pursuant to such direction would be
unduly prejudicial to the interests of Holders of the Securities of all series
so affected not joining in the giving of said direction, it being understood
that (subject to Section 7.1) the Trustee shall have no duty to ascertain
whether or not such actions or forebearances are unduly prejudicial to such
Holders.

                As between the Trustee and the Holders of the Securities,
nothing in this Indenture shall impair the right of the Trustee in its
discretion to take any action deemed proper by the Trustee and which is not
inconsistent with such direction or directions by Securityholders.

        Section 6.10    Waiver of Past Defaults.

        The Holders of not less than a majority in principal amount of the
Outstanding Securities of any series on behalf of the Holders of all the
Securities of such series may waive any past default hereunder with respect to
such series and its consequences, except a default:

        (1)     in the payment of the principal of, any premium or interest on,
or any Additional Amounts with respect to, any Security of such series, or

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

                                      -41-

<PAGE>

                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 6.11    Trustee to Give Notice of Default, But May Withhold in
Certain Circumstances.

        The Trustee shall transmit to the Securityholders of any series, as the
names and addresses of such Holders appear on the Security Register, notice by
mail of all defaults known to a Responsible Officer of the Trustee which have
occurred with respect to such series, such notice to be transmitted within 60
days after the occurrence thereof, unless such defaults shall have been cured
before the giving of such notice (the term "default" or "defaults" for the
purposes of this Section being hereby defined to mean any event or condition
which is, or with notice or lapse of time or both would become, an Event of
Default); provided that, except in the case of default in the payment of the
principal of, or premium, if any, or interest, if any, on, or any Additional
Amounts with respect to, any of the Securities of such series, the Trustee shall
be protected in withholding such notice if and so long as a trust committee of
directors or Responsible Officers of the Trustee in good faith determines that
the withholding of such notice is in the interests of the Securityholders of
such series.

        Section 6.12    Right of Court to Require Filing of Undertaking to Pay
Costs.

        The parties to this Indenture agree, and each Holder of any Security by
his acceptance thereof shall be deemed to have agreed, that any court may in its
discretion require, in any suit for the enforcement of any right or remedy under
this Indenture or in any suit against the Trustee for any action taken, 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 and
expenses, against any party litigant in such suit, having due regard to the
merits and good faith of the claims or defenses made by such party litigant; but
the provisions of this Section shall not apply to any suit instituted by the
Trustee, to any suit instituted by any Securityholder or group of
Securityholders of any series holding in the aggregate more than 10% in
aggregate principal amount of the Securities of such series Outstanding, or, in
the case of any suit relating to or arising under Section 6.1(c) or Section
6.1(i) (if the suit relates to Securities of more than one but fewer than all
series), 10% in aggregate principal amount of Securities Outstanding affected
thereby, or, in the case of any suit relating to or arising under Section 6.1(c)
or Section 6.1(i) (if the suit under clause (d) or (g) relates to all the
Securities then Outstanding), Section 6.1(f) or Section 6.1(g), 10% in aggregate
principal amount of all Securities Outstanding, or to any suit instituted by any
Holder of Securities for the enforcement of the payment of the principal of, or
premium, if any, or interest, if any, on, any Security on or after the due date
expressed in such Security.

        Section 6.13    Waiver of Usury, Stay or Extension Laws.

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

        Section 6.14    Delay or Omission Not Waiver.

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

                             CONCERNING THE TRUSTEE

        Section 7.1     Duties and Responsibilities of the Trustee; During
Default; Prior to Default.

        With respect to the Holders of any series of Securities issued
hereunder, the Trustee, prior to the occurrence of an Event of Default with
respect to the Securities of that series and after the curing or waiving of all
Events of Default which may have occurred with respect to such series,
undertakes to perform such duties and only such duties as are specifically set
forth in this Indenture. In case an Event of Default with respect to the
Securities of a series has occurred (which has not been cured or waived), the
Trustee shall exercise such of the rights and powers vested in it by this
Indenture, and use the same degree of care and skill in their exercise, as a
prudent man would exercise or use under the circumstances in the conduct of his
own affairs.

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

        (a)     prior to the occurrence of an Event of Default with respect to
the Securities of such series and after the curing or waiving of all such Events
of Default with respect to such series which may have occurred:

                (i)     the duties and obligations of the Trustee shall be
        determined solely by the express provisions of this Indenture, and the
        Trustee shall not be liable except for the

                                      -43-

<PAGE>

        performance of such duties and obligations as are specifically set forth
        in this Indenture, and no implied covenants or obligations shall be read
        into this Indenture against the Trustee; and

                (ii)    in the absence of bad faith on the part of the Trustee,
        the Trustee may conclusively rely, as to the truth of the statements and
        the correctness of the opinions expressed therein, upon any statements,
        certificates or opinions furnished to the Trustee and conforming to the
        requirements of this Indenture; but in the case of any such statements,
        certificates or opinions which by any provision hereof are specifically
        required to be furnished to the Trustee, the Trustee shall be under a
        duty to examine the same to determine whether or not they conform to the
        requirements of this Indenture;

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

        (c)     the Trustee shall not be liable with respect to any action taken
or omitted to be taken by it in good faith in accordance with the direction of
the Holders of Securities pursuant to Section 6.9 relating to the time, method
and place of conducting any proceeding for any remedy available to the Trustee,
or exercising any trust or power conferred upon the Trustee, under this
Indenture.

                None of the provisions contained in this Indenture shall require
the Trustee to expend or risk its own funds or otherwise incur personal
financial liability in the performance of any of its duties or in the exercise
of any of its rights or powers, if it shall have reasonable grounds for
believing that the repayment of such funds or adequate indemnity against such
liability is not reasonably assured to it.

        Section 7.2     Certain Rights of the Trustee.

        Subject to Section 7.1:

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

        (b)     any request, direction, order or demand of the Company mentioned
herein shall be sufficiently evidenced by an Officer's Certificate (unless other
evidence in respect thereof be herein specifically prescribed); and any
resolution of the Board of Directors may be evidenced to the Trustee by a copy
thereof certified by the secretary or any assistant secretary of the Company;

        (c)     the Trustee may consult with counsel of its own selection and
any advice or Opinion of Counsel shall be full and complete authorization and
protection in respect of any

                                      -44-

<PAGE>

action taken, suffered or omitted to be taken by it hereunder in good faith and
in accordance with such advice or Opinion of Counsel;

        (d)     the Trustee shall be under no obligation to exercise any of the
trusts or powers vested in it by this Indenture at the request, order or
direction of any of the Securityholders pursuant to the provisions of this
Indenture, unless such Securityholders shall have offered to the Trustee
reasonable security or indemnity satisfactory to it against the costs, expenses
and liabilities which might be incurred therein or thereby;

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

        (f)     prior to the occurrence of an Event of Default hereunder and
after the curing or waiving of all Events of Default, 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, consent, order, approval, appraisal, bond, debenture, note, coupon,
security or other paper or document unless requested in writing so to do by the
Holders of not less than a majority in aggregate principal amount of the
Securities of all series affected then Outstanding; provided that, if the
payment within a reasonable time to the Trustee of the costs, expenses or
liabilities likely to be incurred by it in the making of such investigation is,
in the opinion of the Trustee, not reasonably assured to the Trustee by the
security afforded to it by the terms of this Indenture, the Trustee may require
indemnity reasonably satisfactory to it against such expenses or liabilities as
a condition to proceeding; the reasonable expenses of every such investigation
shall be paid by the Company or, if paid by the Trustee or any predecessor
Trustee, shall be repaid by the Company upon demand;

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

        (h)     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
during reasonable hours and upon reasonable notice the books, records and
premises of the Company, personally or by agent or attorney;

        (i)     the Trustee shall not be deemed to have notice of any Default or
Event of Default unless a Responsible Officer of the Trustee has actual
knowledge thereof or unless written notice of any event which is in fact such a
default is received by the Trustee at the

                                      -45-

Corporate Trust Office of the Trustee, and such notice references the Securities
and this Indenture; and

        (j)     the rights, privileges, protections, immunities and benefits
given to the Trustee, including, without limitation, its right to be
indemnified, are extended to, and shall be enforceable by, the Trustee in each
of its capacities hereunder, and each agent, custodian and other Person
authorized to act hereunder.

        Section 7.3     Trustee Not Responsible for Recitals, Disposition of
Securities or Application of Proceeds Thereof.

        The recitals contained herein and in the Securities, except the
certificates of authentication, shall be taken as the statements of the Company,
and the Trustee assumes no responsibility for the correctness of the same,
except that the Trustee represents that it is duly authorized to execute and
deliver this Indenture, authenticate the Securities and perform its obligations
hereunder and that the statements made by it in a Statement of Eligibility on
Form T-1 supplied to the Company are true and accurate, subject to the
qualifications set forth therein. The Trustee makes no representation as to the
validity or sufficiency of this Indenture or of the Securities. The Trustee
shall not be accountable for the use or application by the Company of any of the
Securities or of the proceeds thereof.

        Section 7.4     Trustee and Agents May Hold Securities; Collections,
etc.

        The Trustee, any Paying Agent, Securities Registrar, Authenticating
Agent or any agent of the Company or the Trustee, in its individual or any other
capacity, may become the owner or pledgee of Securities with the same rights it
would have if it were not the Trustee or such agent, and, subject to Section 7.8
and Section 7.13, if operative, may otherwise deal with the Company and receive,
collect, hold and retain collections from the Company with the same rights it
would have if it were not the Trustee, Paying Agent, Securities Registrar,
Authenticating Agent or such agent.

        Section 7.5     Moneys Held by Trustee.

        Subject to the provisions of Section 12.3, all moneys received by the
Trustee shall, until used or applied as herein provided, be held in trust for
the purposes for which they were received, but need not be segregated from other
funds except to the extent required by mandatory provisions of law. The Trustee
shall have no liability for interest on money it receives and holds in trust
except as specifically provided herein.

        Section 7.6     Compensation and Indemnification of Trustee and Its
Prior Claim.

        The Company covenants and agrees to pay the Trustee from time to time,
and the Trustee shall be entitled to such compensation as the Company and the
Trustee may from time to time agree in writing for all services rendered by the
Trustee hereunder (which compensation shall not be limited by any provision of
law in regard to the compensation of a trustee of an express trust) and the
Company covenants and agrees to pay or reimburse the Trustee and each

                                      -46-

<PAGE>

predecessor trustee upon its request for all reasonable expenses, disbursements
and advances incurred or made by or on behalf of it in accordance with any of
the provisions of this Indenture (including the reasonable compensation and the
expenses and disbursements of its counsel and of all agents and other Persons
not regularly in its employ) except any such expense, disbursement or advance as
shall be attributable to its negligence or bad faith. The Company also covenants
to indemnify the Trustee and each predecessor trustee for, and hold it harmless
against, any loss, liability, damage, claims or expense, including taxes (other
than taxes measured by the income of the Trustee or otherwise applicable to the
Trustee for operations outside the scope of this Indenture) incurred without
negligence or bad faith on its part, arising out of or in connection with the
acceptance or administration of this Indenture or the trusts hereunder and the
performance of its duties hereunder, including the costs and expenses of
defending itself against or investigating any claim of liability in connection
with the exercise or performance of any of its powers or duties hereunder except
to the extent that any such loss, liability, damage, claims or expense shall be
attributable to the Trustee's negligence or bad faith. The obligations of the
Company under this Section to compensate and indemnify the Trustee and each
predecessor trustee and to pay or reimburse the Trustee and each predecessor
trustee for expenses, disbursements and advances shall constitute additional
indebtedness hereunder and shall survive the satisfaction and discharge of this
Indenture and resignation or removal of the Trustee. Such additional
indebtedness shall be a lien prior to that of the Securities upon all property
and funds held or collected by the Trustee as such, except funds held in trust
for the benefit of the Holders of particular Securities.

        Section 7.7     Right of Trustee to Rely on Officer's Certificate, etc.

        Subject to Section 7.1 and Section 7.2, whenever in the administration
of the trusts of this Indenture the Trustee shall deem it necessary or desirable
that a matter be proved or established prior to taking or suffering or omitting
any action hereunder, such matter (unless other evidence in respect thereof be
herein specifically prescribed) may, in the absence of negligence or bad faith
on the part of the Trustee, be deemed to be conclusively proved and established
by an Officer's Certificate delivered to the Trustee, and such certificate, in
the absence of negligence or bad faith on the part of the Trustee, shall be full
warrant to the Trustee for any action taken, suffered or omitted by it under the
provisions of this Indenture upon the good faith thereof.

        Section 7.8     Qualification of Trustee; Conflicting Interests.

        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) of the Trust Indenture Act
with respect to the Securities of any series, there shall be excluded this
Indenture with respect to Securities of any particular series of Securities
other than that series. Nothing herein shall prevent the Trustee from filing
with the Commission the application referred to in the penultimate paragraph of
Section 310(b) of the Trust Indenture Act.

        Section 7.9     Persons Eligible for Appointment as Trustee.

        There shall at all times be a Trustee hereunder for each series of
Securities, which shall be at all times either:

        (a)     a corporation organized and doing business under the laws of the
United States of America or of any State or territory or the District of
Columbia, authorized under such laws to exercise corporate trust powers and
subject to supervision or examination by Federal, State, territory or District
of Columbia authority; or

        (b)     a corporation or other Person organized and doing business under
the laws of a foreign government that is permitted to act as Trustee pursuant to
a rule, regulation or order of the Commission, authorized under such laws to
exercise corporate trust powers, and subject to supervision or examination by
authority of such foreign government or a political subdivision thereof
substantially equivalent to supervision or examination applicable to United
States institutional trustees, in either case 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 requirements of the aforesaid
supervising or examining authority, then for the purposes of this Section 7.9,
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 for the Securities of any series shall
cease to be eligible in accordance with the provisions of this Section 7.9, it
shall resign immediately in the manner and with the effect hereinafter specified
in this Article. Neither the Company nor any Person directly or indirectly
controlling, controlled by, or under common control with the Company shall serve
as Trustee for the Securities of any series issued hereunder.

        Section 7.10    Resignation and Removal; Appointment of Successor
Trustee.

        (a)     The Trustee, or any trustee or trustees hereafter appointed, may
at any time resign by giving written notice of resignation to the Company and by
mailing notice thereof by first-class mail to Holders of the Securities at their
last addresses as they shall appear on the Security Register. Upon receiving
such notice of resignation, the Company shall promptly appoint a successor
trustee or trustees by written instrument in duplicate, executed by authority of
the Board of Directors, one copy of which instrument shall be delivered to the
resigning Trustee and one copy to the successor trustee or trustees. If no
successor trustee shall have been so appointed and have accepted appointment
within 30 days after the mailing of such notice of resignation, the resigning
Trustee may petition at the expense of the Company any court of competent
jurisdiction for the appointment of a successor trustee, or any Securityholder
who has been a bona fide Holder of a Security or Securities for at least six
months may, subject to the provisions of Section 6.12, on behalf of himself and
all others similarly situated, petition any such court for the appointment of a
successor trustee. Such court may thereupon, after such notice, if any, as it
may deem proper and prescribe, appoint a successor trustee.

        (b)     In case at any time any of the following shall occur:

                                      -48-

<PAGE>

                (i)     the Trustee shall fail to comply with the provisions of
        Section 310(b) of the Trust Indenture Act after written request therefor
        by the Company or by any Securityholder who has been a bona fide Holder
        of a Security or Securities for at least six months unless the Trustee's
        duty to resign is stayed in accordance with the provisions of Section
        310(b) of the Trust Indenture Act; or

                (ii)    the Trustee shall cease to be eligible in accordance
        with the provisions of Section 7.9 and shall fail to resign after
        written request therefor by the Company or by any Securityholder; or the
        Trustee shall become incapable of acting, or shall be adjudged a
        bankrupt or insolvent; or a receiver or liquidator of the Trustee or of
        its property shall be appointed, or any public officer shall take charge
        or control of the Trustee or of its property or affairs for the purpose
        of rehabilitation, conservation or liquidation; then, in any case, the
        Company may remove the Trustee and appoint a successor trustee by
        written instrument, in duplicate, executed by order of the Board of
        Directors of the Company, one copy of which instrument shall be
        delivered to the Trustee so removed and one copy to the successor
        trustee, or, subject to the provisions of Section 6.12, any
        Securityholder who has been a bona fide Holder of a Security or
        Securities 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 and the appointment of a successor
        trustee. Such court may thereupon, after such notice, if any, as it may
        deem proper and prescribe, remove the Trustee and appoint a successor
        trustee.

        (c)     The Holders of a majority in aggregate principal amount of the
Securities at the time Outstanding may at any time remove the Trustee and
appoint a successor trustee by delivering to the Trustee so removed, to the
successor trustee so appointed and to the Company the evidence provided for in
Section 8.1 of the action in that regard taken by the Securityholders.

        (d)     No resignation or removal of the Trustee and no appointment of a
successor trustee pursuant to any of the provisions of this Section 7.10 shall
become effective until acceptance of appointment by the successor trustee as
provided in Section 7.11.

        Section 7.11    Acceptance of Appointment by Successor Trustee.

        Any successor trustee appointed as provided in Section 7.10 shall
execute, acknowledge and deliver to the Company and to its predecessor trustee
an instrument accepting such appointment hereunder, and thereupon the
resignation or removal of the predecessor trustee shall become effective and
such successor trustee, without any further act, deed or conveyance, shall
become vested with all rights, powers, duties and obligations of its predecessor
hereunder, with like effect as if originally named as trustee hereunder; but
nevertheless, on the written request of the Company or of the successor trustee,
upon payment of all amounts due to the Trustee under Section 7.6, the Trustee
ceasing to act shall, subject to Section 4.4, pay over to the successor trustee
all moneys at the time held by it hereunder and shall execute and deliver an
instrument transferring to such successor trustee all such rights, powers,
duties and

                                      -49-

<PAGE>

obligations. Upon request of any successor trustee, the Company shall execute
any and all instruments in writing for more fully and certainly vesting in and
confirming to such successor trustee all such rights and powers. Any Trustee
ceasing to act, shall, nevertheless, retain a prior lien upon all property or
funds held or collected by such trustee to secure any amounts then due it
pursuant to the provisions of Section 7.6.

                No successor trustee shall accept appointment as provided in
this Section 7.11 unless at the time of such acceptance such successor trustee
shall be qualified under the provisions of Section 7.8 and eligible under the
provisions of Section 7.9.

                Upon acceptance of appointment by any successor trustee as
provided in this Section 7.11, the Company shall mail notice thereof by
first-class mail to the Holders of Securities at their last addresses as they
shall appear on the Security Register. If the acceptance of appointment is
substantially contemporaneous with the resignation, then the notice called for
by the preceding sentence may be combined with the notice called for by Section
7.10. If the Company fails to mail such notice within 10 days after acceptance
of appointment by the successor trustee, the successor trustee shall cause such
notice to be mailed at the expense of the Company.

        Section 7.12    Merger, Conversion, Consolidation or Succession to
Business of Trustee.

        Any corporation in 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 substantially all of the corporate trust business of
the Trustee, shall be the successor of the trustee hereunder, provided that such
corporation shall be qualified under the provisions of Section 7.8 and eligible
under the provisions of Section 7.9, without the execution or filing of any
paper or any further act (including the giving of any notice to Securityholders)
on the part of any of the parties hereto, anything herein to the contrary
notwithstanding.

                In case at the time such successor to the Trustee shall succeed
to the trusts created by this Indenture any of the Securities shall have been
authenticated but not delivered, any such successor to the Trustee may adopt the
certificate of authentication of any predecessor trustee and deliver such
Securities so authenticated; and, in case at that time any of the Securities
shall not have been authenticated, any successor to the Trustee may authenticate
such Securities either in the name of any predecessor hereunder or in the name
of the successor trustee; and in all such cases such certificate shall have the
full force which it is anywhere in the Securities or in this Indenture provided
for the certificate of authentication of the Trustee.

        Section 7.13    Preferential Collection of Claims Against the Company.

        (a)     Subject to the provisions of this Section, if the Trustee shall
be or shall become a creditor, directly or indirectly, secured or unsecured, of
the Company or any other obligor of the Securities within three months prior to
a default, as defined in Section 7.13(c), or subsequent to such a default, then,
unless and until such default shall be cured, the Trustee shall set apart and

                                      -50-

<PAGE>

hold in a special account for the benefit of the Trustee individually, the
Holders of the Securities and the holders of other indenture securities (as
defined in this Section):

                (i)     an amount equal to any and all reductions in the amount
        due and owing upon any claim as such creditor in respect of principal or
        interest, effected after the beginning of such three months' period and
        valid as against the Company and its other creditors, except any such
        reduction resulting from the receipt or disposition of any property
        described in Section 7.13(a)(ii), or from the exercise of any right of
        set-off which the Trustee could have exercised if a petition in
        bankruptcy had been filed by or against the Company upon the date of
        such default; and

                (ii)    all property received by the Trustee in respect of any
        claim as such creditor, either as security therefor, or in satisfaction
        or composition thereof, or otherwise, after the beginning of such three
        months' period, or an amount equal to the proceeds of any such property,
        if disposed of, subject, however, to the rights, if any, of the Company
        and its other creditors in such property or such proceeds.

                Nothing herein contained, however, shall affect the right of the
        Trustee:

                (A)     to retain for its own account (i) payments made on
                account of any such claim by any Person (other than the Company)
                who is liable thereon, (ii) the proceeds of a bona fide sale of
                any such claim by the Trustee to a third Person, and (iii)
                distributions made in cash, securities or other property in
                respect of claims filed against the Company in bankruptcy or
                receivership or in the proceedings for reorganization pursuant
                to the Federal Bankruptcy Code or applicable state law;

                (B)     to realize, for its own account, upon any property held
                by it as security for any such claim, if such property was so
                held prior to the beginning of such three months' period;

                (C)     to realize, for its own account, but only to the extent
                of the claim hereinafter mentioned, upon any property held by it
                as security for any such claim, if such claim was created after
                the beginning of such three months' period and such property was
                received as security therefor simultaneously with the creation
                thereof, and if the Trustee shall sustain the burden of proving
                that at the time such property was so received the Trustee has
                no reasonable cause to believe that a default as defined by
                Section 7.13(c) would occur within three months; or

                (D)     to receive payment on any claim referred to in paragraph
                (B) or (C) above, against the release of any property held as
                security for such claim as provided in such paragraph (B) or
                (C), as the case may be, to the extent of the fair value of such
                property.

                                      -51-

<PAGE>

                For the purposes of paragraphs (B), (C) and (D), property
substituted after the beginning of such three months' period for property held
as security at the time of such substitution shall, to the extent of the fair
value of the property released, have the same status as the property released,
and, to the extent that any claim referred to in any of such paragraphs is
created in renewal of or in substitution for or for the purpose of repaying or
refunding any pre-existing claim of the Trustee as such creditor, such claim
shall have the same status as such pre-existing claim.

                If the Trustee shall be required to account, the funds and
property held in such special account and the proceeds thereof shall be
apportioned between the Trustee, the Holders of the Securities and the holders
of other indenture securities in such manner that the Trustee, such Holders and
the holders of other indenture securities realize, as a result of payments from
such special account and payments of dividends on claims filed against the
Company in bankruptcy or receivership or in proceedings for reorganization
pursuant to the Federal Bankruptcy Code or applicable state law, the same
percentage of their respective claims, figured before crediting to the claim of
the Trustee anything on account of the receipt by it from the Company of the
funds and property in such special account and before crediting to the
respective claims of the Trustee, Holders of the Securities and the holders of
other indenture securities dividends on claims filed against the Company in
bankruptcy or receivership or in proceedings for reorganization pursuant to the
Federal Bankruptcy Code or applicable state law, but after crediting thereon
receipts on account of the indebtedness represented by their respective claims
from all sources other than from such dividends and from the funds and property
so held in such special account. As used in this paragraph, with respect to any
claim, the term "dividends" shall include any distribution with respect to such
claim, in bankruptcy or receivership or in proceedings for reorganization
pursuant to the Federal Bankruptcy Code or applicable state law, whether such
distribution is made in cash, securities or other property, but shall not
include any such distribution with respect to the secured portion, if any, of
such claim. The court in which such bankruptcy, receivership or proceeding for
reorganization is pending shall have jurisdiction (i) to apportion between the
Trustee, the Holders of Securities and the holders of other indenture
securities, in accordance with the provisions of this paragraph, the funds and
property held in such special account and the proceeds thereof; or (ii) in lieu
of such apportionment, in whole or in part, to give to the provisions of this
paragraph due consideration in determining the fairness of the distributions to
be made to the Trustee, the Holders of Securities and the holders of other
indenture securities with respect to their respective claims, in which event it
shall not be necessary to liquidate or to appraise the value of any securities
or other property held in such special account or as security for any such
claim, or to make a specific allocation of such distribution as between the
secured and unsecured portions of such claims, or otherwise to apply the
provisions of this paragraph as a mathematical formula.

                Any Trustee who has resigned or been removed after the beginning
of such three months' period shall be subject to the provisions of this Section
7.13(a) as though such resignation or removal had not occurred. If any Trustee
has resigned or been removed prior to the beginning of such three months'
period, it shall be subject to the provisions of this Section 7.13(a) if and
only if the following conditions exist:

                                      -52-

<PAGE>

                (E)     the receipt of property or reduction of claim which
                would have given rise to the obligation to account, if such
                Trustee had continued as trustee, occurred after the beginning
                of such three months' period; and

                (F)     such receipt of property or reduction of claim occurred
                within three months after such resignation or removal.

        (b)     There shall be excluded from the operation of this Section a
creditor relationship arising from:

                (i)     the ownership or acquisition of securities issued under
        any indenture, or any security or securities having a maturity of one
        year or more at the time of acquisition by the Trustee;

                (ii)    advances authorized by a receivership or bankruptcy
        court of competent jurisdiction or by this Indenture for the purpose of
        preserving any property which shall at any time be subject to the lien
        of this Indenture or of discharging tax liens or other prior liens or
        encumbrances thereon, if notice of such advance and of the circumstances
        surrounding the making thereof is given to the Holders of the applicable
        series of Securities at the time and in the manner provided in this
        Indenture;

                (iii)   disbursements made in the ordinary course of business in
        the capacity of trustee under an indenture, transfer agent, registrar,
        custodian, paying agent, fiscal agent or depositary, or other similar
        capacity;

                (iv)    an indebtedness created as a result of services rendered
        or premises rented or an indebtedness created as a result of goods or
        securities sold in a cash transaction as defined in Section
        7.13(c)(iii);

                (v)     the ownership of stock or of some other securities of a
        corporation organized under the provisions of Section 25(a) of the
        Federal Reserve Act, as amended, which is directly or indirectly a
        creditor of the Company; or

                (vi)    the acquisition, ownership, acceptance or negotiation of
        any drafts, bills of exchange, acceptances or obligations which fall
        within the classification of self-liquidating paper as defined in
        Section 7.13(c)(iv).

        (c)     As used in this Section:

                (i)     the term "default" shall mean any failure to make
        payment in full of the principal of or interest upon any of the
        Securities of the applicable series or upon the other indenture
        securities when and as such principal or interest becomes due and
        payable;

                (ii)    the term "other indenture securities" shall mean
        securities upon which the Company is an obligor (as defined in the Trust
        Indenture Act) outstanding under any

                                      -53-

<PAGE>

        other indenture (i) under which the Trustee is also trustee, (ii) which
        contains provisions substantially similar to the provisions of Section
        7.13(a), and (iii) under which a default exists at the time of the
        apportionment of the funds and property held in said special account;

                (iii)   the term "cash transaction" shall mean any transaction
        in which full payment for goods or securities sold is made within seven
        days after delivery of the goods or securities in currency or in checks
        or other orders drawn upon banks or bankers and payable upon demand;

                (iv)    the term "self-liquidating paper" shall mean any draft,
        bill of exchange, acceptance or obligation which is made, drawn,
        negotiated or incurred by the Company for the purpose of financing the
        purchase, processing, manufacture, shipment, storage or sale of goods,
        wares or merchandise and which is secured by documents evidencing title
        to, possession of, or a lien upon the goods, wares or merchandise or the
        receivables or proceeds arising from the sale of goods, wares or
        merchandise previously constituting the security, provided that the
        security is received by the Trustee simultaneously with the creation of
        the creditor relationship with the Company arising from the making,
        drawing, negotiating or incurring of the draft, bill of exchange,
        acceptance or obligation; and

                (v)     the term "Company" shall mean any obligor upon the
        Securities.

        Section 7.14    Authenticating Agent.

        So long as any Securities remain Outstanding, if the Corporate Trust
Office of the Trustee is not located in the Borough of Manhattan, The City of
New York, or otherwise upon a Company Request, there shall be an authenticating
agent (the "Authenticating Agent") appointed, for such period as the Company
shall elect, by the Trustee to act as its agent on its behalf and subject to its
direction in connection with the authentication and delivery of Securities.
Securities authenticated by such Authenticating Agent shall be entitled to the
benefits of this Indenture and shall be valid and obligatory for all purposes as
if authenticated by such Trustee. Wherever reference is made in this Indenture
to the authentication and delivery of Securities by the Trustee or to 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
such Trustee by such Authenticating Agent. Such Authenticating Agent shall at
all times be a corporation organized and doing business under the laws of the
United States of America or of any State or of the District of Columbia,
authorized under such laws to exercise corporate trust powers, having a combined
capital and surplus of at least $50,000,000 and subject to supervision or
examination by Federal, State or District of Columbia authority. If the
Corporate Trust Office of the Trustee is not located in the Borough of
Manhattan, The City of New York, the Authenticating Agent shall have its
principal office and place of business in the Borough of Manhattan, The City of
New York.

                                      -54-

<PAGE>

                Any corporation into which any 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 any
Authenticating Agent shall be a party, or any corporation succeeding to the
corporate agency business of any Authenticating Agent, shall continue to be the
Authenticating Agent without the execution or filing of any paper or any further
act on the part of the Trustee or such Authenticating Agent.

                Any Authenticating Agent may at any time, and if it shall cease
to be eligible shall, resign by giving written notice of resignation to the
Trustee and to the Company. The Trustee may at any time terminate the agency of
any Authenticating Agent by giving written notice of termination to such
Authenticating Agent and to the Company. Upon receiving such a notice of
resignation or upon such a termination, or in case at any time any
Authenticating Agent shall cease to be eligible in accordance with the
provisions of this Section 7.14, the Trustee shall upon Company Request appoint
a successor Authenticating Agent, and the Company shall provide notice of such
appointment to all Holders of Securities in the manner and to the extent
provided in Section 14.4. Any successor Authenticating Agent upon acceptance of
its appointment hereunder shall become vested with all rights, powers, duties
and responsibilities of its predecessor hereunder, with like effect as if
originally named as Authenticating Agent herein. The Company agrees to pay or to
cause to be paid to the Authenticating Agent from time to time reasonable
compensation for its services. The Authenticating Agent shall have no
responsibility or liability for any action taken by it as such in good faith at
the direction of the Trustee.

                                    ARTICLE 8
                      CONCERNING THE HOLDERS OF SECURITIES

        Section 8.1     Action by Holders.

        Whenever in this Indenture it is provided that the Holders of a
specified percentage in aggregate principal amount of the Securities of any
series may take any action (including the making of any demand or request, the
giving of any notice, consent or waiver or the taking of any other action) the
fact that at the time of taking any such action the Holders of such specified
percentage have joined therein may be evidenced (a) by any instrument or any
number of instruments of similar tenor executed by Holders in Person or by agent
or proxy appointed in writing, or (b) by the record of Holders voting in favor
thereof at any meeting of such Holders duly called and held in accordance with
the provisions of ARTICLE 9, or (c) by a combination of such instrument or
instruments and any such record of such a meeting of Holders. The Company may
(but shall not be required to) set a record date for purposes of determining the
identity of Securityholders entitled to vote or consent to any action by vote or
consent authorized or permitted under this Indenture, which record date shall be
the later of 10 days prior to the first solicitation of such consent or the date
of the most recent list of Holders furnished to the Trustee pursuant to Section
5.1 of this Indenture prior to such solicitation. If a record date is fixed,
those Persons who were Securityholders at such record date (or their duly
designated proxies), and only those Persons, shall be entitled to take such
action by vote or

                                      -55-

<PAGE>

consent or to revoke any vote or consent previously given, whether or not such
Persons continue to be Holders after such record date.

        Section 8.2     Proof of Execution of Instruments by Holders of
Securities.

        Subject to Section 7.1, Section 7.2 and Section 9.5, the execution of
any instrument by a Holder of a Security or his agent or proxy may be proved in
any reasonable manner that the Trustee deems sufficient, including, without
limitation, in the following manner:

                The fact and date of the execution by any such Person of any
instrument may be proved by the certificate of any notary public or other
officer authorized to take acknowledgments of deeds, that the Person executing
such instrument acknowledged to him the execution thereof, or by an affidavit or
written statement of a witness to such execution. Where such execution is by an
officer of a corporation or association or a member of a partnership on behalf
of such corporation, association or partnership, as the case may be, or by any
other Person acting in a representative capacity, such certificate, affidavit or
written statement shall also constitute sufficient proof of his authority.

                The ownership of Securities shall be proved by the Securities
Register or by a certificate of the Securities Registrar.

                The record of any Holders' meeting shall be proved in the manner
provided in Section 9.6.

        Section 8.3     Holders to be Treated as Owners.

        The Company, the Trustee and any agent of the Company or the Trustee may
deem and treat the Person in whose name any Security shall be registered upon
the Security Register as the absolute owner of such Security (notwithstanding
any notation of ownership or other writing thereon) for the purpose of receiving
payment of principal of, and premium, if any, and (subject to Section 3.6 and
Section 3.8) interest, if any, on, such Security, and for all other purposes
whatsoever, whether or not such Security be overdue, and neither the Company,
the Trustee nor any agent of the Company or the Trustee shall be affected by
notice to the contrary. All such payments so made to any Holder for the time
being, shall be valid, and, to the extent of the sum or sums so paid, effectual
to satisfy and discharge the liability for moneys payable upon such Security.

                None of the Company, the Trustee or any agent of the Company 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 interest
of a Global Security, or for maintaining, supervising or reviewing any records
relating to such beneficial ownership interest. Notwithstanding the foregoing,
with respect to any Global Security, nothing herein shall prevent the Company or
the Trustee or any agent of the Company or the Trustee from giving effect to any
written certification, proxy or other authorization furnished by any Depository
(or its nominee), as a Holder, with respect to such Global Security or impair,
as between such Depository and owners of beneficial interests in such Global
Security, the operation of

                                      -56-

<PAGE>

customary practices governing the exercise of the right of such Depository (or
its nominee) as holder of such Global Security.

        Section 8.4     Securities Owned by Company Deemed Not Outstanding.

        In determining whether the Holders of the requisite aggregate principal
amount of Securities of any or all series have concurred in any direction,
consent or waiver under this Indenture, Securities which are owned by the
Company or any other obligor on the Securities with respect to which such
determination is being made or by any Person directly or indirectly controlling
or controlled by or under direct or indirect common control with the Company or
any other obligor on the Securities with respect to which such determination is
being made shall be disregarded and deemed not to be Outstanding for the purpose
of any such determination, except that for the purpose of determining whether
the Trustee shall be protected in relying on any such direction, consent or
waiver only Securities which a Responsible Officer of the Trustee knows are so
owned shall be so disregarded. Securities so owned which have been pledged in
good faith may be regarded as Outstanding if the pledgee establishes to the
satisfaction of the Trustee the pledgee's right so to act with respect to such
Securities and that the pledgee is not the Company or any other obligor upon the
Securities or any Person directly or indirectly controlling or controlled by or
under direct or indirect common control with the Company or any other obligor on
the Securities. In case of a dispute as to such right, the advice of counsel
shall be full protection in respect of any decision made by the Trustee in
accordance with such advice. Upon request of the Trustee, the Company shall
furnish to the Trustee promptly an Officer's Certificate listing and identifying
all Securities, if any, known by the Company to be owned or held by or for the
account of any of the above-described Persons; and, subject to Section 7.1 and
Section 7.2, the Trustee shall be entitled to accept such Officer's Certificate
as conclusive evidence of the facts therein set forth and of the fact that all
Securities not listed therein are Outstanding for the purpose of any such
determination.

        Section 8.5     Right of Revocation of Action Taken.

        At any time prior to (but not after) the evidencing to the Trustee, as
provided in Section 8.1, of the taking of any action by the Holders of the
percentage in aggregate principal amount of the Securities of any or all series,
as the case may be, specified in this Indenture in connection with such action,
any Holder of a Security, the number, letter or other distinguishing symbol of
which is shown by the evidence to be included in the Securities the Holders of
which have consented to such action, may, by filing written notice at the
Corporate Trust Office and upon proof of holding as provided in this Article,
revoke such action so far as concerns such Security. Except as aforesaid, any
such action taken by the Holder of any Security shall be conclusive and binding
upon such Holder and upon all future Holders and owners of such Security and of
any Securities issued in exchange or substitution therefor, irrespective of
whether or not any notation in regard thereto is made upon any such Security or

        Section 9.4     Qualifications for Voting.

        To be entitled to vote at any meeting of Holders a Person shall be (a) a
Holder of one or more outstanding Securities with respect to which such meeting
is being held or (b) a Person appointed by an instrument in writing as proxy by
such Holder. The only Persons who shall be entitled to be present or to speak at
any meeting of Holders shall be the Persons entitled to vote at such meeting and
their counsel and any representatives of the Trustee and its counsel and any
representatives of the Company and its counsel.

        Section 9.5     Regulations.

        Notwithstanding any other provisions of this Indenture, the Trustee may
make such reasonable regulations as it may deem advisable for any meeting of
Holders of the Securities in regard to proof of the holding of Securities and of
the appointment of proxies, and in regard to the appointment and duties of
inspectors of votes, the submission and examination of proxies, certificates and
other evidence of the right to vote, and such other matters concerning the
conduct of the meeting as it shall think fit.

                The Trustee shall, by an instrument in writing, appoint a
temporary chairman of the meeting, unless the meeting shall have been called by
the Company or by Holders of Securities as provided in Section 9.3, in which
case the Company or the Holders calling the meeting, as the case may be, shall
in like manner appoint a temporary chairman. A permanent chairman and a
permanent secretary of the meeting shall be elected by majority vote of the
meeting.

                Subject to Section 8.4, at any meeting each Holder of Securities
with respect to which such meeting is being held or proxy therefor shall be
entitled to one vote for each $1,000 principal amount (in the case of Original
Issue Discount Securities, such principal amount to be determined as provided in
the definition of "Outstanding") of Securities held or represented by him;
provided, however, that no vote shall be cast or counted at any meeting in
respect of any such Security challenged as not Outstanding and ruled by the
chairman of the meeting to be not Outstanding. The chairman of the meeting shall
have no right to vote other than by virtue of Securities held by him or
instruments in writing aforesaid duly designating him as the Person to vote on
behalf of other Holders. At any meeting of Holders, the presence of Persons
holding or representing Securities with respect to which such meeting is being
held in an aggregate principal amount sufficient to take action on the business
for the transaction of which such meeting was called shall constitute a quorum,
but, if less than a quorum is present, the Persons holding or representing a
majority in aggregate principal amount of such Securities represented at the
meeting may adjourn such meeting with the same effect, for all intents and
purposes, as though a quorum had been present. Any meeting of Holders of
Securities with respect to which a meeting was duly called pursuant to the
provisions of Section 9.2 or Section 9.3 may be adjourned from time to time by
Persons holding or representing a majority in aggregate principal amount of such
Securities represented at the meeting, present, whether or not constituting a
quorum, and the meeting may be held as so adjourned without further notice.

any resolution and who shall make and file with the secretary of the meeting
their verified written reports in duplicate of all votes cast at the meeting. A

taken thereat and affidavits by one or more Persons having knowledge of the
facts setting forth a copy of the notice of the meeting and showing that said

record shall be signed and verified by the affidavits of the permanent chairman
and secretary of the meeting and one of the duplicates shall be delivered to the
Company and the other to the Trustee to be preserved by the Trustee.

                Any record so signed and verified shall be conclusive evidence
of the matters therein stated.

        Section 9.7     No Delay of Rights by Reason of Meeting.

        Nothing in this Article contained shall be deemed or construed to
authorize or permit, by reason of any call of a meeting of Holders or any rights
expressly or impliedly conferred hereunder to make such call, any hindrance or
delay in the exercise of any right or rights conferred upon or reserved to the
Trustee or to the Holders under any of the provisions of this Indenture or of

                Trustee for cancellation, including the principal of, any
                premium and interest on, and any Additional Amounts with respect
                to such Securities (based upon applicable law as in effect on
                the date of such deposit), to the date of such deposit (in the
                case of Securities which have become due and payable) or to the
                Maturity thereof, as the case may be;

                (B)     the Company has irrevocably deposited or caused to be
                irrevocably deposited with the Trustee as obligations in trust
                such amount of Government Obligations as will, in a written
                opinion of independent public accountants delivered to the
                Trustee, together with the predetermined and certain income to
                accrue thereon (without consideration of any reinvestment
                thereof), be sufficient to pay and discharge when due the entire
                indebtedness on all such Outstanding Securities of such series
                for unpaid principal (and premium, if any), interest on, and any
                Additional Amounts to the date of such deposit (in the case of
                Securities which have become due and payable) or Maturity
                thereof, as the case may be;

        (b)     the Company has paid or caused to be paid all other sums payable
with respect to the Outstanding Securities of such series including all fees due
to the Trustee under Section 7.6;

        (c)     the Company has delivered to the Trustee an Officer's
Certificate and an Opinion of Counsel, each stating that all conditions
precedent herein provided for relating to the due satisfaction and discharge of
this Indenture with respect to the entire indebtedness on all Outstanding
Securities of any such series have been complied with; and

        (d)     if the Securities of such series are not to become due and
payable at their Stated Maturity within one year of the date of such deposit or
are not to be called for redemption within one year of the date of such deposit
under arrangements satisfactory to the Trustee as of the date of such deposit,
then the Company shall have given, not later than the date of such deposit,
notice of such deposit to the Holders of the Securities of such series.

        Upon the satisfaction of the conditions set forth in this Section 12.1
with respect to all the Outstanding Securities of any series, the terms and
conditions with respect thereto set forth in this Indenture shall no longer be
binding upon, or applicable to, the Company; provided, however, that the Company
shall not be discharged from (a) any obligations under Section 7.6

                                      -67-

<PAGE>

and Section 7.10 and (b) any obligations under Section 3.6, Section 3.7, Section
5.1 and Section 12.3 and (c) any obligations under Section 4.4, with respect to
the payment of any Additional Amounts, if any, (but only to the extent that the
Additional Amounts payable with respect to any Outstanding Securities of such
series exceed the amount deposited in respect of such Additional Amounts
pursuant to Section 12.1(a)(ii)); and provided, further, that in the event a
petition for relief under the Federal Bankruptcy Code or a successor statute is
filed with respect to the Company within 91 days after the deposit, this
Indenture with respect to the entire indebtedness on all Securities of such
series shall not be discharged, and in such event the Trustee shall return such
deposited funds or obligations as it is then holding to the Company upon Company
Request.

        Section 12.2    Defeasance and Covenant Defeasance.

        (a)     Unless pursuant to Section 3.1, either or both of (i) defeasance
of the Securities of or within a series under clause (b) of this Section 12.2
shall not be applicable with respect to the Securities of such series or (ii)
covenant defeasance of the Securities of or within a series under clause (c) of
this Section 12.2 shall not be applicable with respect to the Securities of such
series, then such provisions, together with the other provisions of this Section
12.2 (with such modifications thereto as may be specified pursuant to Section
3.1 with respect to any Securities), shall be applicable to such Securities and
the Company may at its option by Board Resolution, at any time, with respect to
such Securities, elect to have Section 12.2(b) or Section 12.2(c) be applied to
such Outstanding Securities upon compliance with the conditions set forth below
in this Section 12.2.

        (b)     Upon the Company's exercise of the above option applicable to
this Section 12.2(b) with respect to any Securities of or within a series, the
Company shall be deemed to have been discharged from its obligations with
respect to such Outstanding Securities on the date the conditions set forth in
clause (d) of this Section 12.2 are satisfied (hereinafter, "defeasance"). For
this purpose, such defeasance means that the Company shall be deemed to have
paid and discharged the entire Indebtedness represented by such Outstanding
Securities which shall thereafter be deemed to be "Outstanding" only for the
purposes of clause (c) of this Section 12.2 and the other Sections of this
Indenture referred to in clauses (i) and (ii) below, and to have satisfied all
of its other obligations under such Securities and 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: (i) the rights of Holders of such Outstanding Securities, solely from
the trust fund described in clause (d) of this Section 12.2 and as more fully
set forth in such clause, payments in respect of the principal of (and premium,
if any) and interest, if any, on, and Additional Amounts, if any, with respect
to, such Securities when such payments are due, and any rights of such Holder to
convert such Securities into Common Stock of the Company or exchange such
Securities for other securities; (ii) the obligations of the Company and the
Trustee with respect to such Securities under Sections 3.6, 3.7, 4.2, 4.3 and
12.3 and with respect to the payment of Additional Amounts, if any, on such
Securities as contemplated by Section 4.4 (but only to the extent that the
Additional Amounts payable with respect to such Securities exceed the amount
deposited in respect of such Additional Amounts

                                      -68-

<PAGE>

pursuant to Section 12.2(d)(i) below), and with respect to any rights to convert
such Securities into Common Stock of the Company or exchange such Securities for
other securities; (iii) the rights, powers, trusts, duties and immunities of the
Trustee hereunder including, without limitation, the compensation, reimbursement
and indemnities provided in Section 7.6 herein; and (iv) this Section 12.2. The
Company may exercise its option under this Section 12.2(b) notwithstanding the
prior exercise of its option under clause (c) of this Section 12.2 with respect
to such Securities.

        (c)     Upon the Company's exercise of the option to have this Section
12.2(c) apply with respect to any Securities of or within a series, the Company
shall be released from its obligations in respect of any other covenant
applicable to such Securities, with respect to such Outstanding Securities on
and after the date the conditions set forth in clause (d) of this Section 12.2
are satisfied (hereinafter, "covenant defeasance"), and such Securities shall
thereafter be deemed to be not "Outstanding" for the purposes of any direction,
waiver, consent or declaration or Act of Holders (and the consequences of any
thereof) in connection with any such covenant or obligation, but shall continue
to be deemed "Outstanding" for all other purposes hereunder. For this purpose,
such covenant defeasance means that, with respect to such Outstanding
Securities, the Company may omit to comply with, and shall have no liability in
respect of, any term, condition or limitation set forth in any such Section or
such other covenant or obligation, whether directly or indirectly, by reason of
any reference elsewhere herein to any such Section or such other covenant or
obligation or by reason of reference in any such Section or such other covenant
to any other provision herein or in any other document and such omission to
comply shall not constitute a default or an Event of Default under Section 6.1
but, except as specified above, the remainder of this Indenture and such
Securities shall be unaffected thereby.

        (d)     The following shall be the conditions to application of clause
(b) or (c) of this Section 12.2 to any Outstanding Securities of or within a
series:

                (i)     The Company shall irrevocably have deposited or caused
        to be deposited with the Trustee (or another trustee satisfying the
        requirements of Section 7.8 who shall agree to comply with the
        provisions of this Section 12.2 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, (1) an amount in Dollars or in such Foreign
        Currency in which such Securities are then specified as payable at
        Stated Maturity, or (2) Government Obligations applicable to such
        Securities (determined on the basis of the Currency in which such
        Securities are then specified as payable at Stated Maturity) which
        through the scheduled payment of principal and interest in respect
        thereof in accordance with their terms will provide, not later than one
        day before the due date of any payment with respect to such Securities,
        money in an amount, or (3) a combination thereof, in any case, in an
        amount, sufficient, without consideration of any reinvestment of such
        principal and interest, in the opinion of a nationally recognized firm
        of independent public accountants expressed in a written certification
        thereof delivered to the Trustee, to pay and discharge, and which shall
        be applied by the Trustee (or other qualifying trustee) to pay and
        discharge, (y) the

                                      -69-

<PAGE>

        principal of (and premium, if any) and interest, if any, on, and any
        Additional Amounts with respect to such Securities (based upon
        applicable law as in effect on the date of such deposit), such
        Outstanding Securities at the Stated Maturity or Redemption Date of such
        principal or installment of principal or premium or interest and (z) any
        mandatory sinking fund payments or analogous payments applicable to such
        Outstanding Securities on the days on which such payments are due and
        payable in accordance with the terms of this Indenture and of such
        Securities and, if applicable, shall have made irrevocable arrangements
        satisfactory to the Trustee for the redemption of any Securities to be
        redeemed at the option of the Company in connection with such deposit.

                (ii)    No Event of Default or event which with notice or lapse
        of time or both would become an Event of Default with respect to such
        Securities shall have occurred and be continuing on the date of such
        deposit (after giving effect thereto) and, with respect to defeasance
        only, no event described in Section 6.1(f) or (g) at any time during the
        period ending on the 91st day after the date of such deposit (it being
        understood that this condition shall not be deemed satisfied until the
        expiration of such period).

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

                (iv)    In the case of an election under clause (b) of this
        Section 12.2 for which the Place of Payment is within the United States,
        the Company shall have delivered to the Trustee an Opinion of Counsel
        stating that (i) the Company has received from the Internal Revenue
        Service a letter ruling, or there has been published by the Internal
        Revenue Service a Revenue Ruling, or (ii) since the date of execution of
        this Indenture, there has been a change in the applicable Federal income
        tax law, in either case to the effect that, and based thereon such
        opinion shall confirm that, the Holders of such Outstanding Securities
        will not recognize income, gain or loss for Federal income tax purposes
        as a result of such defeasance and will be subject to Federal income tax
        on the same amounts, in the same manner and at the same times as would
        have been the case if such defeasance had not occurred.

                (v)     In the case of an election under clause (c) of this
        Section 12.2 with respect to Requested Securities and for which the
        Place of Payment is within the United States, the Company shall have
        delivered to the Trustee an Opinion of Counsel to the effect that the
        Holders of such Outstanding Securities will not recognize income, gain
        or loss for Federal income tax purposes as a result of such covenant
        defeasance and will be subject to Federal income tax on the same
        amounts, in the same manner and at the same times as would have been the
        case if such covenant defeasance had not occurred.

                (vi)    With respect to defeasance only, the Company shall have
        delivered to the Trustee an Opinion of Counsel to the effect that, after
        the 91st day after the date of deposit, all money and Government
        Obligations (or other property as may be provided pursuant to Section
        3.1) (including the proceeds thereof) deposited or caused to be

                                      -70-

<PAGE>

        deposited with the Trustee (or other qualifying trustee) pursuant to
        this clause (d) to be held in trust will not be subject to recapture or
        avoidance as a preference in any case or proceeding (whether voluntary
        or involuntary) in respect of the Company under any Federal or State
        bankruptcy, insolvency, reorganization or other similar law, or any
        decree or order for relief in respect of the Company issued in
        connection therewith (for which purpose such Opinion of Counsel may
        assume that no Holder is an "insider").

                (vii)   With respect to defeasance only, the Company shall have
        delivered to the Trustee an Officer's Certificate as to solvency and the
        absence of any intent of preferring the Holders over any other creditors
        of the Company.

                (viii)  The Company shall have delivered to the Trustee an
        Officer's Certificate and an Opinion of Counsel, each stating that all
        conditions precedent to the defeasance or covenant defeasance under
        clause (b) or (c) of this Section 12.2 (as the case may be) have been
        complied with.

                (ix)    Notwithstanding any other provisions of this Section
        12.2(d), such defeasance or covenant defeasance shall be effected in
        compliance with any additional or substitute terms, conditions or
        limitations which may be imposed on the Company in connection therewith
        pursuant to Section 3.1.

        (e)     Unless otherwise specified in or pursuant to this Indenture, if,
after a deposit referred to in Section 12.2(d)(i) has been made, (i) the Holder
of a Security in respect of which such deposit was made is entitled to, and
does, elect pursuant to Section 3.1 or the terms of such Security to receive
payment in a Currency other than that in which the deposit pursuant to Section
12.2(d)(i) has been made in respect of such Security, or (ii) a Conversion Event
occurs in respect of the Foreign Currency in which the deposit pursuant to
Section 12.2(d)(i) has been made, the indebtedness represented by such Security
shall be deemed to have been, and will be, fully discharged and satisfied
through the payment of the principal of (and premium, if any), and interest, if
any, on, and Additional Amounts, if any, with respect to, such Security as the
same becomes due out of the proceeds yielded by converting (from time to time as
specified below in the case of any such election) the amount or other property
deposited in respect of such Security into the Currency in which such Security
becomes payable as a result of such election or Conversion Event based on (x) in
the case of payments made pursuant to clause (i) above, the applicable market
exchange rate for such Currency in effect on the second Business Day prior to
each payment date, or (y) with respect to a Conversion Event, the applicable
market exchange rate for such Foreign Currency in effect (as nearly as feasible)
at the time of the Conversion Event.

                The Company shall pay and indemnify the Trustee (or other
qualifying trustee, collectively for purposes of this Section 12.2(d) and
Section 12.3, the "Trustee") against any tax, fee or other charge, imposed on or
assessed against the Government Obligations deposited pursuant to this Section
12.2 or the principal or interest received in respect thereof other than any
such tax, fee or other charge which by law is for the account of the Holders of
such Outstanding Securities.

                                      -71-

<PAGE>

                Anything in this Section 12.2 to the contrary notwithstanding,
the Trustee shall deliver or pay to the Company from time to time upon Company
Request any money or Government Obligations (or other property and any proceeds
therefrom) held by it as provided in clause (d) of this Section 12.2 which, in
the opinion of a nationally recognized firm of independent public accountants
expressed in a written certification thereof delivered to the Trustee, are in
excess of the amount thereof which would then be required to be deposited to
effect a defeasance or covenant defeasance, as applicable, in accordance with
this Section 12.2.

        Section 12.3    Application of Trust Money.

        All money and obligations deposited with the Trustee pursuant to Section
12.1 or 12.2 shall be held irrevocably in trust and shall be made under the
terms of an escrow trust agreement in form and substance satisfactory to the
Company and the Trustee. Such money and obligations shall be applied by the
Trustee, in accordance with the provisions of the Securities, this Indenture and
such escrow trust agreement, to the payment, either directly or through any
Paying Agent (including the Company acting as its own Paying Agent) as the
Trustee may determine, to the Persons entitled thereto, of the principal of (and
premium, if any) and interest, if any, on the Securities for the payment of
which such money and obligations have been deposited with the Trustee. If
Securities of any series are to be redeemed prior to their Stated Maturity,
whether pursuant to any optional redemption provisions or in accordance with any
mandatory or optional sinking fund requirement, the Company shall give the
required notice of redemption or shall make such arrangements as are
satisfactory to the Trustee for the giving of notice of redemption by the
Trustee in the name, and at the expense, of the Company.

        Section 12.4    Repayment of Moneys Held by Paying Agent.

        In connection with the satisfaction and discharge of this Indenture with
respect to Securities of any series, all moneys with respect to such series then
held by any Paying Agent (and not required for such satisfaction and discharge)
shall, upon demand of the Company, be repaid to it or paid to the Trustee and
thereupon such Paying Agent shall be released from all further liability with
respect to such moneys.

        Section 12.5    Return of Unclaimed Moneys Held by Trustee and Paying
Agent.

        Any moneys deposited with or paid to the Trustee or any Paying Agent for
the payment of the principal of, or premium, if any, or interest, if any, on,
Securities of any series and which shall not be applied but shall remain
unclaimed by the Holders of Securities of such series for two years after the
date upon which such payment shall have become due and payable, shall be repaid
to the Company by the Trustee on demand; and the Holder of any of such
Securities entitled to receive such payment shall thereafter look only to the
Company for the payment thereof; provided, however, that the Company or the
Trustee, before making any such repayment, shall at the expense of the Company
cause to be published once a week for two successive weeks (in each case on any
day of the week) in an Authorized Newspaper, or mail to each Holder, or both, a
notice that said moneys have not been so applied and that after a date

                                      -72-

<PAGE>

named therein any unclaimed balance of said moneys then remaining will be
returned to the Company.

        If the Trustee or Paying Agent is unable to apply any money in
accordance with Section 12.3 by reason of any order or judgment of any court or
governmental authority enjoining, restraining or otherwise prohibiting such
application, then the Company's obligations under this Indenture and the
Securities shall be revived and reinstated as though no deposit had occurred
pursuant to Section 12.1 or Section 12.2 until such time as the Trustee or
Paying Agent is permitted to apply all such money in accordance with Section
12.3; provided, however, that if the Company makes any payment of interest on or
principal of, or any Additional Amounts, with respect to any 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 Paying Agent.

                                   ARTICLE 13
                           SUBORDINATION OF SECURITIES

        Section 13.1    Agreement to Subordinate.

        The Company covenants and agrees, and each Holder of Securities issued
hereunder and under any indenture supplemental hereto or pursuant to a Board
Resolution and Officers' Certificate ("Additional Provisions") by such Holder's
acceptance thereof likewise covenants and agrees, that all Securities shall be
issued subject to the provisions of this ARTICLE 13; and each Holder of a
Security, whether upon original issue or upon transfer or assignment thereof,
accepts and agrees to be bound by such provisions.

        The payment by the Company of the principal of, any premium and interest
on and any Additional Amounts with respect to all Securities of each series
issued hereunder and under any Additional Provisions shall, to the extent and in
the manner hereinafter set forth and subject to the provisions of the related
supplemental indenture, be subordinate in right of payment to the prior payment
in full of all Senior Indebtedness with respect to such series, whether
outstanding at the date of this Indenture or thereafter incurred.

        No provision of this ARTICLE 13 shall prevent the occurrence of any
default or Event of Default hereunder.

        Section 13.2    Default on Senior Indebtedness.

        In the event and during the continuation of any default by the Company
in the payment of principal, premium, interest or any other amount due on any
Senior Indebtedness with respect to the Securities of any series, or in the
event that the maturity of any Senior Indebtedness with respect to the
Securities of any series has been accelerated because of a default, then, in
either case, no payment shall be made by the Company with respect to the
principal (including redemption and sinking fund payments) of, any premium or
interest on, or any Additional Amounts with respect to, the Securities of such
series or to acquire such Securities (other than pursuant to the conversion of
such Securities).

                                      -73-

<PAGE>

        In the event that, notwithstanding the foregoing, any payment shall be
received by the Trustee when such payment is prohibited by the preceding
paragraph of this Section 13.2, such payment shall be held in trust for the
benefit of, and shall be paid over or delivered to, the holders of such Senior
Indebtedness or their respective representatives, or to the trustee or trustees
under any indenture pursuant to which any of such Senior Indebtedness may have
been issued, as their respective interests may appear, but only to the extent
that the holders of such Senior Indebtedness (or their representative or
representatives or a trustee) notify the Trustee in writing within 90 days of
such payment of the amounts then due and owing on such Senior Indebtedness and
only the amounts specified in such notice to the Trustee shall be paid to the
holders of such Senior Indebtedness.

        Section 13.3    Liquidation; Dissolution; Bankruptcy.

        Upon any payment by the Company or distribution of assets of the Company
of any kind or character, whether in cash, property or securities, to creditors
upon any total or partial dissolution, winding-up, reorganization, assignment
for the benefit of creditors or marshaling of assets of the Company, whether
voluntary or involuntary, or in bankruptcy, insolvency, receivership or other
similar proceedings relating to the Company or its assets, all amounts due upon
all Senior Indebtedness with respect to the Securities of any series shall first
be paid in full, or payment thereof provided for in money in accordance with its
terms, before any payment is made by the Company on account of the principal of,
premium or interest on, or Additional Amounts with respect to, the Securities of
such series; and in any such case, any payment by the Company, or distribution
of assets of the Company of any kind or character, whether in cash, property or
securities, to which the Holders or the Trustee (on behalf of Holders with
respect to the principal of, premium or interest on or Additional Amounts with
respect to, the Securities of such Series) would be entitled to receive from the
Company, except for the provisions of this ARTICLE 13, shall be paid by the
Company or by any receiver, trustee in bankruptcy, liquidating trustee, agent or
other Person making such payment or distribution, or by the Holders or by the
Trustee under this Indenture if received by them or it, directly to the holders
of such Senior Indebtedness (pro rata to such holders having equal seniority on
the basis of the respective amounts of such Senior Indebtedness held by such
holders, as calculated by the Company) or their representative or
representatives, or to the trustee or trustees under any indenture pursuant to
which any instruments evidencing such Senior Indebtedness may have been issued,
as their respective interests may appear, to the extent necessary to pay such
Senior Indebtedness in full, in money or money's worth, after giving effect to
any concurrent payment or distribution to or for the holders of such Senior
Indebtedness, before any payment or distribution is made to the Holders of the
Securities of such series or to the Trustee.

        In the event that, notwithstanding the foregoing, any payment or
distribution of assets of the Company of any kind or character, whether in cash,
property or securities, prohibited by the foregoing shall be received by the
Trustee before all such Senior Indebtedness is paid in full, or provision is
made for such payment in money in accordance with its terms, such payment or
distribution shall be held in trust for the benefit of and shall be paid over or
delivered to the holders of such Senior Indebtedness or their representative or
representatives, or to the trustee

                                      -74-

<PAGE>

or trustees under any indenture pursuant to which any instruments evidencing
such Senior Indebtedness may have been issued, as their respective interests may
appear, as calculated by the Company, for application to the payment of all such
Senior Indebtedness remaining unpaid to the extent necessary to pay such Senior
Indebtedness in full in money in accordance with its terms, after giving effect
to any concurrent payment or distribution to or for the benefit of the holders
of such Senior Indebtedness.

        For purposes of this ARTICLE 13, the words "cash, property or
securities" shall not be deemed to include common shares of the Company as

if such other Person shall, as a part of such consolidation, amalgamation,
merger, conveyance or transfer, comply with the conditions stated in ARTICLE 11
of this Indenture.

        Subject to the payment in full of all Senior Indebtedness with respect

Indebtedness to receive payments or distributions of cash, property or
securities of the Company applicable to such Senior Indebtedness until the
principal of, any premium and interest on, and any Additional Amounts with
respect to, the Securities of such series shall be paid in full; and, for the
purposes of such subrogation, no payments or distributions to the holders of
such Senior Indebtedness of any cash, property or securities to which the
Holders or the Trustee would be entitled except for the provisions of this
ARTICLE 13, and no payment over pursuant to the provisions of this ARTICLE 13 to
or for the benefit of the holders of such Senior Indebtedness by Holders of the
Securities of such series or the Trustee, shall, as between the Company, its
creditors other than holders of such Senior Indebtedness, and the Holders of the
Securities of such series, be deemed to be a payment by the Company to or on
account of such Senior Indebtedness. It is understood that the provisions of
this ARTICLE 13 are and are intended solely for the purposes of defining the
relative rights of the Holders of the Securities of each series, on the one
hand, and the holders of the Senior Indebtedness with respect to the Securities
of such series on the other hand.

        Nothing contained in this ARTICLE 13 or elsewhere in this Indenture, any
Additional Provisions or in the Securities of any series is intended to or shall
impair, as between the

respect to the Securities of such series, and the Holders of the Securities of
such series, the obligation of the Company, which is absolute and unconditional,
to pay to the Holders of the Securities of such series the principal of, any
premium and interest on, and any Additional Amounts with respect to, the
Securities of such series as and when the same shall become due and payable in
accordance with their terms, or is intended to or shall affect the relative
rights of the Holders of the Securities of such series and creditors of the
Company, other than the holders of such Senior Indebtedness, nor shall anything
herein or therein prevent the Trustee or the Holder of any Security of such
series from exercising all remedies otherwise permitted by applicable law upon
default under this Indenture, subject to the rights, if any, under this ARTICLE
13 of the holders of such Senior Indebtedness in respect of cash, property or
securities of the Company, as the case may be, received upon the exercise of any
such remedy.

        Upon any payment or distribution of assets of the Company referred to in
this ARTICLE 13, the Trustee, subject to the provisions of ARTICLE 7 of this
Indenture, and the Holders shall be entitled to conclusively rely upon any order
or decree made by any court of competent jurisdiction in which such dissolution,
winding-up, liquidation or reorganization proceedings are pending, or a
certificate of the receiver, trustee in bankruptcy, liquidation trustee, agent
or other Person making such payment or distribution, delivered to the Trustee or
to the Holders of the Securities of any series, for the purposes of ascertaining
the Persons entitled to participate in such distribution, the holders of Senior
Indebtedness with respect to the Securities of such series and other
indebtedness of the Company, as the case may be, the amount thereof or payable
thereon, the amount or amounts paid or distributed thereon and all other facts
pertinent thereto or to this ARTICLE 13.

        Section 13.5    Trustee to Effectuate Subordination.

        Each Holder of Securities by such Holder's acceptance thereof authorizes
and directs the Trustee on such Holder's behalf to take such action as may be
necessary or appropriate to effectuate the subordination provided in this
ARTICLE 13 and appoints the Trustee such Holder's attorney-in-fact for any and
all such purposes.

        Section 13.6    Notice by the Company.

        The Company shall give prompt written notice to a Responsible Officer of
the Trustee of any fact known to the Company that would prohibit the making of
any payment of monies to or by the Trustee in respect of the Securities of any
series pursuant to the provisions of this ARTICLE 13. Notwithstanding the
provisions of this ARTICLE 13 or any other provision of this Indenture or any
Additional Provisions, the Trustee shall not be charged with knowledge of the
existence of any facts that would prohibit the making of any payment of monies
to or by the Trustee in respect of the Securities of any series pursuant to the
provisions of this ARTICLE 13, unless and until a Responsible Officer of the
Trustee shall have received written notice thereof from the Company or a holder
or holders of Senior Indebtedness with respect to the Securities of such series
or from any trustee therefor; and before the receipt of any such written notice,
the Trustee, subject to the provisions of ARTICLE 7 of this Indenture, shall be
entitled

                                      -76-

<PAGE>

in all respects to assume that no such facts exist; provided, however, that if
the Trustee shall not have received the notice provided for in this Section 13.6
at least two Business Days prior to the date upon which by the terms hereof any
money may become payable for any purpose (including, without limitation, the
payment of the principal of, any premium or interest on, or any Additional
Amounts with respect to, any Security of such series), then, anything herein
contained to the contrary notwithstanding, the Trustee shall have full power and
authority to receive such money and to apply the same to the purposes for which
they were received, and shall not be affected by any notice to the contrary that
may be received by it within two Business Days prior to such date.

        The Trustee, subject to the provisions of ARTICLE 7 of this Indenture,
shall be entitled to conclusively rely on the delivery to it of a written notice
by a Person representing himself to be a holder of Senior Indebtedness with
respect to the Securities of any series (or a trustee on behalf of such holder),
to establish that such notice has been given by a holder of such Senior
Indebtedness or a trustee on behalf of any such holder or holders. In the event
that the Trustee determines in good faith that further evidence is required with
respect to the right of any Person as a holder of such Senior Indebtedness to
participate in any payment or distribution pursuant to this ARTICLE 13, the
Trustee may request such Person to furnish evidence to the reasonable
satisfaction of the Trustee as to the amount of such Senior Indebtedness held by
such Person, the extent to which such Person is entitled to participate in such
payment or distribution and any other facts pertinent to the rights of such
Person under this ARTICLE 13, and, if such evidence is not furnished, the
Trustee may defer any payment to such Person pending judicial determination as
to the right of such Person to receive such payment.

        Upon any payment or distribution of assets of the Company referred to in
this ARTICLE 13, the Trustee and the Holders shall be entitled to conclusively
rely upon any order or decree entered by any court of competent jurisdiction in
which such insolvency, bankruptcy, receivership, liquidation, reorganization,
dissolution, winding-up or similar case or proceeding is pending, or a
certificate of the trustee in bankruptcy, liquidating trustee, custodian,
receiver, assignee for the benefit of creditors, agent or other Person making
such payment or distribution, delivered to the Trustee or to the Holders of the
Securities of any series, for the purpose of ascertaining the Persons entitled
to participate in such payment or distribution, the holders of Senior
Indebtedness with respect to the Securities of such series and other
indebtedness of the Company, the amount thereof or payable thereon, the amount
or amounts paid or distributed thereon and all other facts pertinent thereto or
to this ARTICLE 13.

        Section 13.7    Rights of the Trustee; Holders of Senior Indebtedness.

        The Trustee in its individual capacity shall be entitled to all the
rights set forth in this ARTICLE 13 in respect of any Senior Indebtedness with
respect to the Securities of any series at any time held by it, to the same
extent as any other holder of such Senior Indebtedness, and nothing in this
Indenture or any Additional Provisions shall deprive the Trustee of any of its
rights as such holder.

                                      -77-

<PAGE>

        With respect to the holders of Senior Indebtedness with respect to the
Securities of any series, the Trustee undertakes to perform or to observe only
such of its covenants and obligations as are specifically set forth in this
ARTICLE 13, and no implied covenants or obligations with respect to the holders
of such Senior Indebtedness shall be read into this Indenture or any Additional
Provisions against the Trustee. The Trustee shall not be deemed to owe any
fiduciary duty to the holders of such Senior Indebtedness and, subject to the
provisions of ARTICLE 7 of this Indenture, the Trustee shall not be liable to
any holder of such Senior Indebtedness if it shall mistakenly or otherwise pay
over or deliver to Holders of the Securities of such series, the Company or any
other Person money or assets to which any holder of such Senior Indebtedness
shall be entitled by virtue of this ARTICLE 13 or otherwise.

        Nothing in this ARTICLE 13 shall apply to claims of, or payments to, the
Trustee under or pursuant to Section 7.6.

        Section 13.8    Subordination May Not Be Impaired.

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

        Without in any way limiting the generality of the foregoing paragraph,
the holders of Senior Indebtedness with respect to the Securities of any series
may, at any time and from time to time, without the consent of or notice to the
Trustee or the Holders of Securities of such series, without incurring
responsibility to such Holders and without impairing or releasing the
subordination provided in this ARTICLE 13 or the obligations hereunder of the
Holders of the Securities of such series to the holders of such Senior
Indebtedness, do any one or more of the following: (i) change the manner, place
or terms of payment or extend the time of payment of, or renew or alter, such
Senior Indebtedness, or otherwise amend or supplement in any manner such Senior
Indebtedness or any instrument evidencing the same or any agreement under which
such Senior Indebtedness is outstanding; (ii) sell, exchange, release or
otherwise deal with any property pledged, mortgaged or otherwise securing such
Senior Indebtedness; (iii) release any Person liable in any manner for the
collection of such Senior Indebtedness; and (iv) exercise or refrain from
exercising any rights against the Company and any other Person.

        Amounts deposited in trust with the Trustee pursuant to and in
accordance with this Indenture, including without limitation pursuant to ARTICLE
12 hereof, shall be for the sole benefit of the Holders of the Securities and,
to the extent allocated for the payment of Securities, shall not be subject to
the subordination provisions of this ARTICLE 13. Otherwise, any deposit of
assets with the Trustee or any Paying Agent (whether or not in trust) for the
payment of any Securities shall be subject to the provisions of Sections 13.1,
13.2, and 13.3;

                                      -78-

provided that, if prior to two Business Days preceding the date on which by the
terms of this Indenture any such assets may become distributable for any purpose
(including, without limitation, the payment of any amount due on any Security)
the Trustee or such Paying Agent shall not have received with respect to such
assets the written notice provided for in Section 13.6, then the Trustee or such
Paying Agent shall have full power and authority to receive such assets and to
apply the same to the purpose for which they were received, and shall not be
affected by any notice to the contrary which may be received by it on or after
such date.

        Section 14.1    Incorporators, Shareholders, Officers and Directors of
Company Exempt from Individual Liability.

        No recourse under or upon any obligation, covenant or agreement
contained in this Indenture, or in any Security, or for any claim based thereon
or otherwise in respect thereof, or because of any indebtedness evidenced
thereby, shall be had against any incorporator, as such, or against any past,
present or future shareholder, officer or director, as such, of the Company or
of any successor, either directly or through the Company or any successor, under
any rule of law, statute or constitutional provision or by the enforcement of
any assessment or by any legal or equitable proceeding or otherwise it being
expressly understood that this Indenture and the obligations issued hereunder
are solely corporate obligations, and that no such personal liability whatever
shall attach to, or is or shall be incurred by, the incorporators, shareholders,
officers or directors, as such, of the Company, or any of them, because of the
creation of the indebtedness hereby authorized, or under or by reason of the
obligations, covenants or agreements contained in this Indenture or in any
Security or implied therefrom; and that any and all such personal liability of
every name and nature, either at common law or in equity or by constitution or
statute, of, and any and all such rights and claims against, every such
incorporator, shareholder, officer or director, as such, because of the creation
of the indebtedness hereby authorized, or under or by reason of the obligations,
covenants or agreements contained in this Indenture or in any Security or
implied therefrom, are hereby expressly waived and released as a condition of,
and as a consideration for, the execution of this Indenture and the issuance of
such Security.

        Section 14.2    Provisions of Indenture for the Sole Benefit of Parties
and Securityholders.

        Nothing in this Indenture or in the Securities, expressed or implied,
shall give or be construed to give to any Person, other than the parties hereto
and their successors, the Holders of the Securities and holders of Senior
Indebtedness, any legal or equitable right, remedy or claim under this Indenture
or under any covenant or provision herein contained, all such covenants and
provisions being for the sole benefit of the parties hereto and their successors
and the Holders of the Securities.

        Section 14.3    Successors and Assigns of Company Bound by Indenture.

        All the covenants, stipulations, promises and agreements in this
Indenture contained by or on behalf of the Company shall bind its successors and
assigns, whether so expressed or not.

        Section 14.4    Notices 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 by first-class mail, postage prepaid, to such Holders
as their names and addresses appear on the Securities Register within the time
prescribed.

                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 on such waiver. 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, and any notice which is mailed in the manner
herein provided shall be conclusively presumed to have been duly given. In the
case by reason of the suspension of regular mail service or by reason of any
other cause it shall be impracticable to give such notice by mail, then such
notification as shall be made with the approval of the Trustee shall constitute
a sufficient notification for every purpose hereunder. In case by reason of the
suspension of publication of any Authorized Newspapers or by reason of any other
cause it shall be impracticable to publish any notice to Holders otherwise
required or permitted under this Indenture, then such notification as shall be
given with the approval of the Trustee shall constitute sufficient notice to
such Holders for every purpose hereunder.

        Section 14.5    Addresses for Notices.

        Any notice or demand which by any provision of this Indenture is
required or permitted to be given or served by the Trustee or by the Holders of

mail addressed (until another address is filed by the Company with the Trustee)
as follows: Montpelier Re Holdings Ltd., Mintflower Place, 8 Par-La-Ville Road,
Hamilton HM 08, Bermuda, Attention: Chief Operating Officer. Any notice,
direction, request or demand by the Company or any Holders of Securities of any
series to or upon the Trustee shall be deemed to have been sufficiently given or
made, for all purposes, if received at the Corporate Trust Office of such
Trustee.

        Section 14.6    Officer's Certificates and Opinions of Counsel;
Statements to Be Contained Therein.

        Upon any application or demand by the Company to the Trustee to take any
action under any of the provisions of this Indenture, the Company shall furnish

with which constitutes a condition precedent), if any, provided for in this
Indenture relating to the proposed action have been complied with and an Opinion
of Counsel stating that in the opinion of such counsel all such conditions
precedent (including any covenants compliance with which constitutes a condition
precedent) have been complied with, except that in the case of any such
application or demand as to which the furnishing of such documents is
specifically required by any provision of this Indenture relating to such
particular application or demand, no additional certificate or opinion need be
furnished.

                Each certificate or opinion provided for in this Indenture

to the Trustee with respect to compliance with a condition or covenant provided
for in this Indenture shall include (a) a statement that the Person making such

statement as to the nature and scope of the examination or investigation upon
which the statements or opinions contained in such certificate or opinion are
based, (c) a statement that, in the opinion of such Person, he has made such
examination or investigation as is necessary to enable him to express an
informed opinion as to whether or not such covenant or condition has been
complied with and (d) a statement as to whether or not, in the opinion of such
Person, such condition or covenant has been complied with.

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

                Any certificate, statement or opinion of an officer of the
Company or of counsel may be based, insofar as it relates to accounting matters,

        In case any provision of this Indenture or of 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 14.8    Legal Holidays.

        In any case where any Interest Payment Date, Redemption Date or Stated
Maturity of any Security shall not be a Business Day in any Place of Payment,
then (notwithstanding any other provision of this Indenture or of the
Securities, other than a provision in Securities of any series, or any Tranche
thereof, or in the indenture supplemental hereto, Board Resolution or Officer's
Certificate that establishes the terms of the Securities of such series or
Tranche, which specifically states that such provision shall apply in lieu of
this Section) payment of interest or principal and premium, if any, need not be
made at such Place of Payment on such date, but may be made on the next
succeeding Business Day at such Place of Payment with the same force and effect
as if made on the Interest Payment Date or Redemption Date, or at the Stated
Maturity, and, if such payment is made or duly provided for on such Business
Day, no interest shall accrue on the amount so payable for the period from and
after such Interest Payment Date, Redemption Date or Stated Maturity, as the
case may be, to such Business Day.

Indenture Act.

        If and to the extent that any provision of this Indenture limits,
qualifies or conflicts with a provision of the Trust Indenture Act that is
required under such Act to be a part of and govern this Indenture, the latter
provision shall control. If any provision of this Indenture modifies or excludes
any provision of the Trust Indenture Act that may be so modified or excluded,
the former provision shall control.

        Section 14.10   Governing Law.

        This Indenture and each Security shall be deemed to be a contract
governed by and construed in accordance with the laws of the State of New York
applicable to agreements made or instruments entered into and, in each case,
performed in said state.

        Section 14.11   Judgment Currency.

        The Company agrees, to the fullest extent that it may effectively do so
under applicable law, that (a) if for the purpose of obtaining judgment in any
court it is necessary to convert the sum due in respect of the principal of, or
premium or interest, if any, or Additional Amounts on the Securities of any
series (the "Required Currency") into a currency in which a judgment will be
rendered (the "Judgment Currency"), the rate of exchange used shall be the rate
at which in accordance with normal banking procedures the Trustee could purchase
in the City of New York the requisite amount of the Required Currency with the
Judgment Currency on the New York Banking Day preceding the day on which a final
unappealable judgment is given and (b) its obligations under this Indenture to
make payments in the Required Currency (i) shall not

                                      -82-

<PAGE>

be discharged or satisfied by any tender, or any recovery pursuant to any
judgment (whether or not entered in accordance with clause (a)), in any currency
other than the Required Currency, except to the extent that such tender or
recovery shall result in the actual receipt, by the payee, of the full amount of
the Required Currency expressed to be payable in respect of such payments, (ii)
shall be enforceable as an alternative or additional cause of action for the
purpose of recovering in the Required Currency the amount, if any, by which such
actual receipt shall fall short of the full amount of the Required Currency so
expressed to be payable and (iii) shall not be affected by judgment being
obtained for any other sum due under this Indenture. For purposes of the
foregoing, "New York Banking Day" means any day except a Saturday, Sunday or a
legal holiday in The City of New York or a day on which banking institutions in
The City of New York are authorized or obligated by law, regulation or executive
order to be closed.

        Section 14.12   No Security Interest Created.

        Nothing in this Indenture or in any Securities, express or implied,

effect in any jurisdiction where property of the Company or its Subsidiaries is
or may be located.

        Section 14.13   Submission to Jurisdiction.

        The Company agrees that any judicial proceedings instituted in relation
to any matter arising under this Indenture, the Securities appertaining thereto
may be brought in any United States Federal or New York State court sitting in
the Borough of Manhattan, The City of New York, New York to the extent that such
court has subject matter jurisdiction over the controversy, and, by execution
and delivery of this Indenture, the Company hereby irrevocably accepts,
generally and unconditionally, the jurisdiction of the aforesaid courts,
acknowledges their competence and irrevocably agrees to be bound by any judgment
rendered in such proceeding. The Company also irrevocably and unconditionally
waives for the benefit of the Trustee and the Holders of the Securities any
immunity from jurisdiction and any immunity from legal process (whether through
service or notice, attachment prior to judgment, attachment in the aid of
execution, execution or otherwise) in respect of this Indenture. The Company
hereby irrevocably designates and appoints for the benefit of the Trustee and
the Holders of the Securities for the term of this Indenture CT Corporation

Road, Hamilton HM 08, Bermuda, Attention: Chief Financial Officer) brought
against it with respect to any such proceeding in any such court in The City of
New York, such service being hereby acknowledged by the Company to be effective
and binding service on it in every respect whether or not the Company shall then
be doing or shall have at any time done business in New York. Such appointment
shall be irrevocable so long as any of the Securities or the obligations of the
Company hereunder remain outstanding until the appointment of a successor by the
Company and such successor's acceptance of such appointment. Upon such
acceptance, the Company shall notify the Trustee in writing of the name and
address of such successor. The Company further agrees for the benefit of the

                                      -83-

<PAGE>

Securities to take any and all action, including the execution and filing of any
and all such documents and instruments, as its agent in full force and effect so
long as any of the Securities or the obligations of the Company hereunder shall
be outstanding. The Trustee shall not be obligated and shall have no
responsibility with respect to any failure by the Company to take any such
action. Nothing herein shall affect the right to serve process in any other
manner permitted by any law or limit the right of the Trustee or any Holder to
institute proceedings against the Company in the courts of any other
jurisdiction or jurisdictions.

least 30 days but no more than 60 days prior to such Redemption Date to the
Holders of Securities of such series so to be redeemed as a whole or in part in
the manner provided in Section 14.4, unless a different period is specified in
the Securities to be redeemed. The notice provided in the manner herein
specified shall be conclusively presumed to have been duly given, whether or not
the Holder receives such notice. In any case, failure to give such notice or any
defect in the notice to the Holder of any Security of a series designated for
redemption as a whole or in part shall not affect the validity of the
proceedings for the redemption of any other Security of such series.

                Each such notice of redemption shall specify the Redemption
Date, the Redemption Price, the CUSIP or other comparable number, the Place or
Places of Payment, that the Securities of such series are being redeemed at the
option of the Company pursuant to provisions contained in the terms of the
Securities of such series or in a supplemental indenture

                                      -84-

<PAGE>

establishing such series, if such be the case, together with a brief statement
of the facts permitting such redemption, that payment will be made upon
presentation and surrender of the applicable Securities at the Place or Places
of Payment, that the Redemption Price together with any interest accrued and
Additional Amounts to the Redemption Date will be paid as specified in said
notice, and that on and after said Redemption Date any interest thereon or on
the portions thereof to be redeemed will cease to accrue, and any information
that is required to be included therein by the Depository.

                If fewer than all the Securities of any series are to be
redeemed the notice of redemption shall specify the numbers of the Securities of
such series to be redeemed. In case any Security of any series is to be redeemed
in part only, the notice of redemption shall state the portion of the principal
amount thereof to be redeemed and shall state that on and after the Redemption
Date, upon surrender of such Security, a new Security or Securities of such
series in principal amount equal to the unredeemed portion thereof will be
issued, or, in the case of Securities providing appropriate space for such
notation, at the option of the Holders the Trustee, in lieu of delivering a new
Security or Securities as aforesaid, may make a notation on such Security of the
payment of the redeemed portion thereof.

                On or before the Redemption Date with respect to the Securities
of any series stated in the notice of redemption given as provided in this
Section 15.2, the Company will deposit with the Trustee or with one or more
Paying Agents an amount of money (except as otherwise specified as contemplated
by Section 3.1 for the Securities of such series or if the Company is acting as
its own Paying Agent, segregate and hold in trust as provided in Section 4.3)
sufficient to redeem on such Redemption Date all the Securities or portions
thereof so called for redemption at the applicable Redemption Price, together
with accrued interest on and Additional Amounts with respect thereto, to such
Redemption Date.

                If fewer than all the Securities of any series, or any Tranche
thereof, are to be redeemed, the Company shall give notice of redemption to the
Trustee not less than 60 days prior to the Redemption Date as to the aggregate
principal amount of Securities to be redeemed.

                If a Holders' Redemption Agreement, as hereinafter defined, is
not on file with the Trustee and in effect, the particular Securities to be
redeemed shall be selected by the Trustee, from the Outstanding Securities of
such series or Tranche not previously called for redemption, substantially pro
rata, by lot or by any other method the Trustee considers fair and appropriate
and that complies with the requirements of the principal national securities
exchange, if any, on which such Securities are listed, and which may provide for
the selection for redemption of portions (equal to the minimum authorized
denomination for Securities of that series or Tranche or any integral multiple
thereof) of the principal amount of Securities of such series or Tranche of a
denomination larger than the minimum authorized denomination for Securities of
that series or Tranche; provided that in case the Securities of such series or
Tranche have different terms and maturities, the Securities to be redeemed shall
be selected by the Company and the Company shall give notice thereof to the
Trustee; provided, however, that if, as indicated in an Officer's Certificate,
the Company shall have offered to purchase all or any principal amount of the
Securities then Outstanding of any series, or any Tranche thereof, and

                                      -85-

<PAGE>

fewer than all of such Securities as to which such offer was made shall have
been tendered to the Company for such purchase, the Trustee, if so directed by
Company Order, shall select for redemption all or any principal amount of such
Securities which have not been so tendered.

                If the Trustee shall use "CUSIP" numbers in notices as a
convenience to Holders, then any such notice may state that no representation is
made as to the correctness of such numbers either as printed on the Securities
or as contained in any notice of a redemption and that reliance may be placed
only on the other identification numbers printed on the Securities, and any such
redemption shall not be affected by any defect in or omission of such numbers.
The Company will promptly notify the Trustee in writing of any change in the
"CUSIP" numbers.

                If at the time the Company shall have given notice of redemption
to the Trustee in accordance with Section 15.2, there shall be on file with the
Trustee and in effect a Holders' Redemption Agreement, as hereinafter defined,
then the Trustee shall select, in accordance with the provisions of said
Holders' Redemption Agreement, the Securities or parts thereof to be redeemed.

                For the purposes of this Indenture, the term "Holders'
Redemption Agreement" shall mean an agreement, reasonably satisfactory to the
Trustee, executed as provided in this Section, which provides for the method to
be followed by the Trustee in selecting Securities or parts of Securities for
redemption out of any funds held by the Trustee to be applied to such
redemption. A Holders' Redemption Agreement may be made with respect to a single
series of Securities, or Tranche thereof, in which case it shall be executed by
or on behalf of the Holders of all Outstanding Securities of such series or
Tranche, or it may be made with respect to all Outstanding Securities in which
case it shall be executed by or on behalf of the Holders of all Securities
Outstanding hereunder.

                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.

        Section 15.3    Payment of Securities Called for Redemption.

        If notice of redemption has been given as above provided and the Company
has deposited, on or before the Redemption Date, with the Trustee (and/or having
irrevocably directed the Trustee to apply, from money held by it available to be
used for the redemption of Securities) an amount in cash sufficient to redeem
all of the Securities to be redeemed, the Securities or portions of Securities
of the series specified in such notice shall become due and payable on the
Redemption Date, and at the place or places stated in such notice at the
applicable Redemption Price, together with any interest accrued to such
Redemption Date, and on and after said Redemption Date any interest on the
Securities or portion of Securities of any series so called for redemption shall
cease to accrue. On presentation and surrender of such Securities at a Place of
Payment in such notice specified, such Securities or the specified portions
thereof shall be paid and redeemed by the Company at the applicable Redemption

                                      -86-

<PAGE>

Price, together with any interest accrued and Additional Amounts to the
Redemption Date, except that if such Redemption Date is an Interest Payment
Date, interest shall be paid as provided in Section 3.8.

                Upon presentation of any Security redeemed in part only, the
Company shall execute and the Trustee shall authenticate and make available for
delivery to or on the order of the Holder thereof, at the expense of the
Company, a new Security or Securities of such series, of authorized
denominations, in principal amount equal to the unredeemed portion of the
Security so presented.

                If a Security in global form is so surrendered, the Company
shall execute, and the Trustee shall authenticate and deliver to the U.S.
Depository or other Depository for such Security in global form as shall be
specified in the Company Order with respect thereto to the Trustee, without
service charge, a new Security in global form in a denomination equal to and in
exchange for the unredeemed portion of the principal of the Security in global
form so surrendered.

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

                                   ARTICLE 16
                                  SINKING FUNDS

        Section 16.1    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 3.1 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".

        Section 16.2    Satisfaction of Mandatory Sinking Fund Payment with
Securities.

        In lieu of making all or any part of any mandatory sinking fund payment
with respect to any Securities of a series in cash, the Company may at its
option, at any time but not less than 45 days prior to the date on which such
sinking fund payment is due, deliver to the Trustee Securities of such series
theretofore purchased or otherwise acquired by the Company, except Securities of
such series which have been redeemed through the application of mandatory
sinking fund payments pursuant to the terms of the Securities of such series,
accompanied by a company order instructing the Trustee to credit such
obligations and stating that the Securities of such series were originally
issued by the Company by way of bona fide sale or other negotiation for value;
provided that such Securities have not been previously so credited. Such

                                      -87-

<PAGE>

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 mandatory sinking fund and the amount of such mandatory sinking fund
payment shall be reduced accordingly.

        Section 16.3    Redemption of Securities for Sinking Fund.

        Not less than 60 days prior to each sinking fund payment date for any
series of Securities, the Company will deliver to the Trustee a certificate
signed by a Vice President, the Treasurer or any Assistant Treasurer of the
Company specifying the amount of the next ensuing sinking fund payment for such
series pursuant to the terms of such 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 such series pursuant
to Section 16.2 and whether the Company intends to exercise its rights to make a
permitted optional sinking fund payment with respect to such series. Such
certificate shall be irrevocable and upon its delivery the Company shall be
obligated to make the cash payment or payments therein referred to, if any, on
or before the next succeeding sinking fund payment date. In the case of the
failure of the Company to deliver such certificate (or to deliver the
Securities, if any, specified in such certificate within the time period
specified in Section 16.2), unless otherwise agreed by the Trustee, the sinking
fund payment due on the next succeeding sinking fund payment date for such
series shall be paid entirely in cash and shall be sufficient to redeem the
principal amount of the Securities of such series subject to a mandatory sinking
fund payment without the right to deliver or credit Securities as provided in
Section 16.2 and without the right to make any optional sinking fund payment, if
any, with respect to such series.

                Any sinking fund payment or payments (mandatory or optional)
made in cash plus any unused balance of any preceding sinking fund payments made
with respect to the Securities of any particular series shall be applied by the
Trustee (or by the Company if the Company is acting as its own Paying Agent) on
the sinking fund payment date on which such payment is made (or, if such payment
is made before a sinking fund payment date, on the sinking fund payment date
following the date of such payment) to the redemption of Securities of such
series at the Redemption Price specified in such Securities with respect to the
sinking fund together with accrued interest, if any, to the applicable
Redemption Date. Any sinking fund moneys not so applied or allocated by the
Trustee (or by the Company if the Company is acting as its own Paying Agent) to
the redemption of Securities shall be added to the next sinking fund payment
received by the Trustee (or if the Company is acting as its own Paying Agent,
segregated and held in trust as provided in Section 4.3) for such series and,
together with such payment (or such amount so segregated) shall be applied in
accordance with the provisions of this Section 16.3. Any and all sinking fund
moneys with respect to the Securities of any particular series held by the
Trustee (or if the Company is acting as its own Paying Agent, segregated and
held in trust as provided in Section 4.3) on the last sinking fund payment date
with respect to Securities of such series and not held for the payment or
redemption of particular Securities of such series shall be applied by the
Trustee (or by the Company if the Company is acting as its own Paying Agent),
together with other moneys, if necessary, to be deposited (or segregated)
sufficient for the purpose, to the payment of the principal of the Securities of
such series at Maturity.

                                      -88-

<PAGE>

                The Trustee shall select or cause to be selected the Securities
to be redeemed upon such sinking fund payment date in the manner specified in
Section 15.2 and the Company shall cause notice of the redemption thereof to be
given in the manner provided in Section 15.2 except that the notice of
redemption shall also state that the Securities are being redeemed by operation
of the sinking fund and whether the sinking fund payment is mandatory or
optional, or both, as the case may be. Such notice having been duly given, the
redemption of the Securities shall be made upon the terms and in the manner
stated in Section 15.3.

                On or before each sinking fund payment date, the Company shall
pay to the Trustee (or, if the Company is acting as its own Paying Agent, will
segregate and hold in trust as provided in Section 4.3) in cash a sum equal to
the principal and any interest accrued to the Redemption Date for Securities or
portions thereof to be redeemed on such sinking fund payment date pursuant to
this Section.

                Neither the Trustee nor the Company shall redeem any Securities
of a series with sinking fund moneys or mail any notice of redemption of
Securities of such series by operation of the sinking fund for such series
during the continuance of a default in payment of interest, if any, on any
Securities of such series or of any Event of Default (other than an Event of
Default occurring as a consequence of this paragraph) with respect to the
Securities of such series, except that if the notice of redemption shall have
been provided in accordance with the provisions hereof, the Trustee (or the
Company if the Company is acting as its own Paying Agent) shall redeem such
Securities if cash sufficient for that purpose shall be deposited with the
Trustee (or segregated by the Company) for that purpose in accordance with the
terms of this Article. Except as aforesaid, any moneys in the sinking fund for
such series at the time when any such default or Event of Default shall occur
and any moneys thereafter paid into such sinking fund shall, during the
continuance of such default or Event of Default, be held as security for the
payment of the Securities of such series; provided, however, that in case such
Event of Default or default shall have been cured or waived as provided herein,
such moneys shall thereafter be applied on the next sinking fund payment date
for the Securities of such series on which such moneys may be applied pursuant
to the provisions of this Section.
