     in a permanent global Security) only upon receipt of certain certificates
     or other documents or satisfaction of other conditions, or if Securities of
     the series are initially issuable in temporary global form and if owners of
     beneficial interests therein may exchange such interest for an interest in
     a permanent global Security only upon receipt of certain certificates or
     other documents or satisfaction of other conditions, then the form and/or
     terms of such certificates, documents or conditions;

          (4) the date or dates (and whether fixed or extendible) on which the
     principal of Securities of the series is payable;

                                      -8-


          (5) the rate or rates at which Securities of the series shall bear
     interest, or the method of determining the same, if any, the date or dates
     from which such interest shall accrue, or the method of determining the
     same, if any, the Interest Payment Dates (and whether fixed or extendible)
     and the Regular Record Dates;

          (6) the place or places where the principal of and any interest on
     Securities of the series shall be payable;

          (7) any provisions relating to the issuance of Securities of such
     series at an original issue discount (including, without limitation, the
     issue price thereof, the rate or rates at which such original issue
     discount shall accrue, if any, and the date or dates from or to which or
     period or periods during which such original issue discount shall accrue at
     such rate or rates);

          (8) the price or prices at which, the period or periods within which
     and the terms and conditions upon which Securities of the series may be
     redeemed or otherwise purchased, in whole or in part, at the option of the
     Company, pursuant to any sinking fund or otherwise (including, without
     limitation, the form or method of payment thereof if other than in cash);

          (9) the obligation, if any, of the Company to redeem, purchase or
     repay Securities of the series pursuant to any sinking fund or analogous
     provisions or at the option of a Securityholder thereof and the price or
     prices at which and the period or periods within which and the terms and
     conditions upon which Securities of the series shall be redeemed, purchased
     or repaid, in whole or in part, pursuant to such obligation (including,
     without limitation, the form or method of payment thereof, if other than in
     cash);

          (10) if other than denominations of $25 and any integral multiple
     thereof, the denominations in which Securities of the series shall be
     issuable;

          (11) if other than the principal amount thereof, the portion of the
     principal amount of Securities of the series which shall be payable upon
     acceleration of the maturity thereof pursuant to Section 6.02 or provable
     in bankruptcy pursuant to Section 6.09;


<PAGE>
                                      -9-


          (12) any Events of Default with respect to the Securities of a
     particular series in lieu of or in addition to those set forth herein and
     the remedies therefor;

          (13) the terms of the subordination of Securities of the series; and

          (14) any other terms of a particular series and any other provisions
     expressing or referring to the terms and conditions upon which the
     Securities of that series are to be issued under this Indenture, which
     terms and provisions are not in conflict with the provisions of this
     Indenture; provided, however, that the addition to or subtraction from or
     variation of Articles Four, Five, Six and Eight (and Sections 1.01 and
     1.02, insofar as they relate to the definition of certain terms as used in
     such Articles) with regard to the Securities of a particular series shall
     not be deemed to constitute a conflict with the provisions of those
     Articles.

     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 such
resolution of the Board of Directors or in any such indenture supplemental
hereto. Not all Securities of any one series need be issued at the same time,
and, unless otherwise so provided, a series may be reopened for issuances of
additional Securities of such series.

     If any of the terms of the Securities of a series are established by action
taken pursuant to a resolution of the Board of Directors or indenture
supplemental hereto, a copy of an appropriate record of such action shall be
certified by the Secretary or an Assistant Secretary of the Company and
delivered to the Trustee with an Officers' Certificate setting forth the terms
or the manner of determining the terms of the Securities of such series. With
respect to Securities of a series which are not to be issued at one time, such
resolution of the Board of Directors or action may provide general terms or
parameters for Securities of such series and provide either that the specific
terms of particular Securities of such series shall be specified in a written
order of the Company or that such terms shall be determined by the Company or
its agents in accordance with a written order of the Company as contemplated by
the proviso clause of the fourth paragraph of Section 2.04.


<PAGE>
                                      -10-


SECTION 2.03. Denominations.

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

SECTION 2.04. Execution and Authentication.

     Two Officers shall sign the Securities for the Company by manual or
facsimile signature. The Company's seal shall be reproduced on the Securities.

     If an Officer whose signature is on a Security no longer holds that office
at the time the Trustee authenticates the Security, the Security shall be valid
nevertheless.

     A Security shall not be entitled to any benefit under this Indenture or be
valid for any purpose until the Trustee manually signs the certificate of
authentication on the Security. The signature shall be conclusive evidence that
the Security has been authenticated under this Indenture. Notwithstanding the
foregoing, if any Security shall have been duly authenticated and delivered
hereunder but never issued and sold by the Company, and the Company shall
deliver such Security to the Trustee for cancellation as provided in Section
2.12 together with a written statement (which need not comply with Sections
11.04 and 11.05 and need not be accompanied by an Opinion of Counsel) stating
that such Security has not been issued and sold by the Company, for all purposes
of this Indenture such Security shall be deemed not to have been authenticated
and delivered hereunder and shall not be entitled to the benefits of this
Indenture.

     At any time and from time to time after the execution and delivery of this
Indenture, the Company may deliver Securities of any series executed by the
Company to the Trustee for authentication, and the Trustee shall authenticate
and deliver said Securities to or upon the written order of the Company, signed
by two Officers or by an Officer and an Assistant Treasurer of the Company,
without any further action by the Company. Such written order shall specify the
date on which said Securities shall be authenticated; provided, however, that if
not all the Securities of a series are to be issued at one time and if the
resolution of the Board of Directors or indenture supplemental hereto
establishing such series as contemplated by Sec-


<PAGE>
                                      -11-


tions 2.01 and 2.02 shall so permit, such written order may set forth procedures
acceptable to the Trustee for the issuance of such Securities and for
determining the form or terms of particular Securities of such series including,
but not limited to, interest rate, maturity date, date of issuance and date from
which interest shall accrue.

     If the form or forms or terms of the Securities of the series have been
established in or pursuant to one or more resolutions of the Board of Directors
or indentures supplemental hereto as permitted by Sections 2.01 and 2.02, in
authenticating such Securities, and accepting the additional responsibilities
under this Indenture in relation to such Securities, the Trustee shall be
entitled to receive, and (subject to Section 7.01) shall be fully protected in
relying upon, an Opinion of Counsel stating:

          (1) if the form or forms of such Securities has been established by or
     pursuant to a resolution of the Board of Directors or indenture
     supplemental hereto, that such form or forms has been established in
     conformity with the provisions of this Indenture;

          (2) if the terms of such Securities have been established by or
     pursuant to a resolution of the Board of Directors or indenture
     supplemental hereto, that such terms have been established in conformity
     with the provisions of this Indenture; and

          (3) 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 have been duly issued
     and will constitute valid and legally binding obligations of the Company,
     enforceable in accordance with their terms, subject to bankruptcy,
     insolvency, fraudulent conveyance, reorganization and other laws of general
     applicability relating to or affecting the enforcement of creditors' rights
     and to general equitable principles;

provided, however, that, with respect to Securities of a series which are not to
be issued at one time, the Trustee shall be entitled to receive such Opinion of
Counsel only once at or prior to the time of the first authentication of
Securities of such series and that the opinions described in clauses (2) and (3)
above may state, respectively,


<PAGE>
                                      -12-


          (a) that, when the terms of such Securities shall have been
     established pursuant to a written order of the Company or pursuant to such
     procedures as may be specified from time to time by a written order of the
     Company, all as contemplated by and in accordance with a resolution of the
     Board of Directors or an Officers' Certificate pursuant to a resolution of
     the Board of Directors or indenture supplemental hereto, as the case may
     be, such terms will have been established in conformity with the provisions
     of this Indenture; and

          (b) that such Securities, when (i) executed by the Company, (ii)
     completed, authenticated and delivered by the Trustee in accordance with
     this Indenture, (iii) issued and delivered by the Company and (iv) paid
     for, all as contemplated by and in accordance with the aforesaid written
     order of the Company or specified procedures, as the case may be, will have
     been duly issued and will constitute valid and legally binding obligations
     of the Company, enforceable in accordance with their terms, subject to
     bankruptcy, insolvency, fraudulent conveyance, reorganization and other
     laws of general applicability relating to or affecting the enforcement of
     creditors' rights and to general equitable principles.

     Notwithstanding the provisions of Sections 2.01, 2.02, 11.04 and this
Section, if all the Securities of a series are not to be originally issued at
one time, the resolution of the Board of Directors or indenture supplemental
hereto, and certified copy of the record of action taken pursuant to such
resolution or supplemental indenture, the Officers' Certificate, the written
order of the Company and any other documents otherwise required pursuant to such
Sections need not be delivered at or prior to the time of authentication of each
Security of such series if such documents are delivered at or prior to the
authentication upon original issuance of the first Security of such series to be
issued; provided, however, that any subsequent request by the Company to the
Trustee to authenticate 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 Officers' Certificate delivered pursuant to Section
11.04 at or prior to authentication of the first such Security shall be true and
correct on the date thereof 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 issuance of such
Securities pursuant to


<PAGE>
                                      -13-


this Indenture will affect the Trustee's own rights, duties or immunities under
the Securities and this Indenture or otherwise in a manner which is not
reasonably acceptable to the Trustee.

     With respect to Securities of a series which are not all issued at one
time, the Trustee may conclusively rely, as to the authorization by the Company
of any of such Securities, the form and terms thereof and the legality,
validity, binding effect and enforceability thereof, upon the Opinion of
Counsel, Officers' Certificate and other documents delivered pursuant to
Sections 2.01, 2.02, 11.04 and this Section, as applicable, at or prior to the
time of the first authentication of Securities of such series unless and until
such opinion, certificate or other documents have been superseded or revoked. In
connection with the authentication and delivery of Securities of a series which
are not all issued at one time, the Trustee shall be entitled to assume that the
Company's instructions to authenticate and deliver such Securities do not
violate any rules, regulations or orders of any governmental agency or
commission having jurisdiction over the Company.

SECTION 2.05. Registrar and Paying Agent.

     The Company shall maintain an office or agency where Securities of each
series may be presented for registration of transfer or for exchange
("Registrar"), and an office or agency where Securities of each series may be
presented for payment ("Paying Agent"). The Registrar shall keep a register of
the Securities of each series issued hereunder and of their transfer and
exchange. The Company may have one or more co-Registrars (provided that there
shall be only one register, which shall be maintained by the principal
Registrar) and one or more additional paying agents with respect to any series.
The term "Paying Agent" includes any additional paying agent.

     The Company shall enter into an appropriate agency agreement with any Agent
not a party to this Indenture. The agreement shall implement the provisions of
this Indenture that relate to such Agent. The Company shall promptly notify the
Trustee of the name and address of any such Agent. If the Company fails to
maintain a Registrar or Paying Agent, the Trustee shall act as such.

     The Company initially appoints the Trustee Registrar and Paying Agent for
each series.


<PAGE>
                                      -14-


SECTION 2.06. Paying Agent to Hold Money and Securities in Trust.

     Subject to any applicable terms of the Securities of the relevant series
relating to subordination (as contemplated by Article Ten and Section 2.02),
each Paying Agent shall hold in trust for the benefit of Securityholders of such
series or the Trustee all money and securities held by the Paying Agent for the
payment of any amount in respect of the Securities of such series, and shall
notify the Trustee of any default by the Company in making any such payment. If
the Company or a Subsidiary acts as Paying Agent, it shall segregate such money
and securities and hold it as a separate trust fund. The Company at any time may
require a Paying Agent to pay all money and securities held by it to the Trustee
and account for any funds or securities disbursed. Upon doing so the Paying
Agent shall have no further liability for the money or securities.

SECTION 2.07. Securityholder Lists.

     The Trustee shall preserve in as current a form as is reasonably
practicable the most recent list available to it of the names and addresses of
Securityholders. If the Trustee is not the Registrar, the Company shall furnish
to the Trustee on or before either (1) [April 1] and [October 1] in each year in
the case of Original Issue Discount Securities of any series which by their
terms do not bear interest prior to maturity (other than upon a default in any
payment upon such a Security) or (2) each Interest Payment Date for the
Securities of any other series, but in no event less frequently than
semi-annually, and at such other times as the Trustee may request in writing a
list in such form and as of such date as the Trustee may reasonably require of
the names and addresses of Securityholders.

SECTION 2.08. Transfer and Exchange.

     Where a Security is presented to the Registrar or a co-Registrar with a
request to register a transfer, the Registrar shall register the transfer as
requested if its requirements for such transfer are met. Notwithstanding any
other provision of this Section, unless and until it is exchanged in whole or in
part for Securities in definitive form, a global Security representing all or a
portion of the Securities of or within a series may not be transferred except as
a whole by the depositary for such series to a nominee of such depositary or by
a nominee of such depositary to such depositary or another nominee of such
depositary or by such depositary or any such


<PAGE>
                                      -15-


nominee to a successor depositary for such series or a nominee of such successor
depositary. Where Securities are presented to the Registrar or a co-Registrar
with a request to exchange them for an equal aggregate principal amount of
Securities of the same series of other authorized denominations, the Registrar
shall make the exchange as requested (other than with respect to a global
Security, except as provided below or as otherwise specified as contemplated by
Section 2.02) if its requirements for such exchange are met. The Registrar shall
require, among other things, that any Security presented or surrendered for
transfer or exchange be duly endorsed, or be accompanied by appropriate transfer
documents duly endorsed, or be accompanied by appropriate transfer documents
duly executed, by the Holder thereof or his attorney duly authorized in writing.
To permit transfers and exchanges, the Trustee shall authenticate Securities at
the Registrar's request. Any exchange or transfer shall be without charge,
except that the Company may require payment of a sum sufficient to cover any tax
or other governmental charge that may be imposed in relation thereto.

     The Registrar need not transfer or exchange any Security selected for
redemption or purchase (except, in the case of Securities to be redeemed or
purchased in part, the portion thereof not to be redeemed or purchased) any
Security in respect of which a notice requiring the purchase or redemption
thereof by the Company at the option of the Holder has been given and not
withdrawn by the Holder thereof in accordance with the terms of such Securities
(except in the case of Securities to be so purchased or redeemed in part, the
portion thereof not to be so purchased or redeemed) or transfer or exchange
Securities of any particular series during a period of 15 days before a
selection of Securities of such series to be redeemed.

     Except as otherwise provided with respect to the Securities of any series
as contemplated by Section 2.02, a global Security may be exchanged only as
provided below in this Section.

     If at any time the depositary with respect to a global Security
representing all or a portion of the Securities of or within a series notifies
the Company that it is unwilling, unable or ineligible to continue as such
depositary, the Company shall appoint a successor depositary with respect to
such Securities. Unless otherwise provided with respect to a series of
Securities as contemplated by Section 2.02, if a successor depositary is not so
appointed by the Company within 90


<PAGE>
                                      -16-


days after the Company receives such notice, the Company will execute and the
Trustee, upon receipt of a written order of the Company as contemplated by
Section 2.04 for the authentication and delivery of definitive Securities of
such series (or, if such written order has previously been delivered, then upon
receipt of written instructions from the person or persons specified in such
written order), will authenticate and deliver Securities of such series in
definitive form equal in aggregate principal amount to the principal amount of
the global Security or Securities representing such series in exchange for such
global Security or Securities.

     The Company may at any time and in its sole discretion determine that the
Securities of any series issued in the form of one or more global Securities
shall no longer be represented by such global Security or Securities. In such
event the Company will execute and the Trustee, upon receipt of a written order
of the Company as contemplated by Section 2.04 for the authentication and
delivery of definitive Securities of such series (or, if such written order has
previously been delivered, then upon receipt of written instructions from the
person or persons specified in such written order), will authenticate and
deliver Securities of such series in definitive form equal in aggregate
principal amount to the principal amount of the global Security or Securities
representing such series in exchange for such global Security or Securities.

     If a global Security is otherwise exchangeable as specified by the Company
pursuant to Section 2.02(3) with respect to a series of Securities, the
depositary with respect to a global Security representing all or a portion of
the Securities of or within such series may surrender such global Security to
the Trustee, as the Company's agent for such purpose, to be exchanged in whole
or in part for Securities of such series in definitive form in the manner and
under the circumstances so specified and on such terms as are acceptable to the
Company and such depositary. In such event, the Company shall execute and the
Trustee shall authenticate and deliver or make available for delivery:

          (i) to each Person specified by such depositary a new Security or
     Securities of the same series and of like tenor, of any authorized form and
     denomination as requested by such Person in aggregate principal amount
     equal to and in exchange for such Person's beneficial interest in the
     global Security; and


<PAGE>
                                      -17-


          (ii) unless endorsement of the surrendered global Security as
     contemplated by Section 2.15 or another procedure is specified for the
     Securities of such series as contemplated by Section 2.02, to such
     depositary 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 Securities delivered pursuant to clause
     (i) above in exchange for beneficial interests in such surrendered global
     Security.

     In any exchange provided for in any of the preceding three paragraphs, the
Company will execute and the Trustee will authenticate and deliver Securities in
definitive registered form in authorized denominations.

     Upon the exchange of a global Security for Securities in definitive form,
such global Security shall be cancelled by the Trustee, unless endorsement of
the surrendered global Security as contemplated by Section 2.15 or another
procedure is specified for the Securities of such series as contemplated by
Section 2.02. 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 depositary for such global Security, pursuant to
instructions from its direct or indirect participants or otherwise, shall
instruct the Trustee. The Trustee shall deliver such Securities to the persons
in whose names such Securities are so registered.

     If a Security is issued in exchange for any portion of a global Security
after the close of business at the office or agency where such exchange occurs
(i) on any Regular Record Date and before the opening of business at such office
or agency on the relevant Interest Payment Date, or (ii) on any special record
date and before the opening of business at such office or agency on the related
date for payment of defaulted interest, interest or defaulted interest, as the
case may be, will not be payable on such Interest Payment Date or proposed date
for payment, as the case may be, in respect of such Security, but will be
payable on such Interest Payment Date or proposed date for payment, as the case
may be, only to the Person to whom interest in respect of such portion of such
global Security is payable in accordance with the provisions of this Indenture.

     All Securities issued upon any registration of transfer or exchange of
Securities shall be the valid obligations of the Company, evidencing the same
debt, and entitled to the same


<PAGE>
                                      -18-


benefits under this Indenture, as the Securities surrendered upon such
registration of transfer or exchange.

SECTION 2.09. Replacement Securities.

     If a mutilated Security is surrendered to the Registrar or if the Holder of
a Security claims that the Security has been lost, destroyed or wrongfully
taken, then 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 issue and
the Trustee shall authenticate a replacement Security if the Trustee's
requirements are met. If required, such Holder shall furnish an indemnity bond
sufficient in the judgment of the Company and the Trustee to protect the
Company, the Trustee or any Agent from any loss which any of them may suffer if
a Security is replaced. Upon the issuance of any new Security under this
Section, the Company may require the payment of a sum sufficient to cover any
tax or other governmental charge that may be imposed in relation thereto and any
other expenses (including the fees and expenses of the Trustee) connected
therewith.

     In case any such lost, destroyed or wrongfully-taken Security has become or
is about to become due and payable, or is about to be purchased by the Company
pursuant to any provision of the Securities of such series providing for the
purchase thereof at the option of the Holder or the Company, the Company in its
discretion may, instead of issuing a new Security, pay or purchase such
Security.

     Every new Security issued pursuant to this Section in lieu of any lost,
destroyed or wrongfully-taken Security shall constitute a separate obligation of
the Company, whether or not the lost, destroyed or wrongfully-taken Security
shall be at any time enforceable by anyone, and shall be entitled to all the
benefits of this Indenture equally and proportionately with any and all other
Securities of such series duly issued hereunder.

     The provisions of this Section, as amended or supplemented pursuant to this
Indenture with respect to particular Securities or generally, shall be exclusive
and shall preclude (to the extent lawful) all other rights and remedies with
respect to the replacement or payment of mutilated, lost, destroyed or
wrongfully-taken Securities.

                                      -19-


SECTION 2.10. Outstanding Securities.

     Securities outstanding at any time are all Securities authenticated by the
Trustee except for those cancelled by it, those delivered to it for cancellation
and those described in this Section as not being outstanding. A Security does
not cease to be outstanding because the Company or one of its Affiliates holds
the Security.

     If a Security is replaced pursuant to Section 2.09, it ceases to be
outstanding unless the Trustee receives proof satisfactory to it that the
replaced Security is held by a bona fide purchaser.

     If the Paying Agent holds on a redemption date or maturity date or on the
Business Day following a date on which Securities of such series are to be
purchased by the Company pursuant to any provision thereof providing for such
purchase at the option of the Holder or the Company, money (or securities if
permitted by the terms of such Securities) in trust or, if the Company, acting
as its own Paying Agent, sets aside and segregates money (or securities if
permitted by the terms of such Securities) in trust, sufficient to pay
Securities payable on that date, then, on and after that date such Securities
cease to be outstanding and interest, if any (and original issue discount, if
Original Issue Discount Securities), on them ceases to accrue, unless the Paying
Agent is restricted under the terms of the Securities of such series (specified
as contemplated by Section 2.02) in applying such money.

SECTION 2.11. Temporary Securities.

     Pending the preparation of a permanent global Security or definitive
Securities of any series, the Company may execute and the Trustee, upon the
written order of the Company pursuant to Section 2.04, shall authenticate and
deliver temporary Securities. Temporary Securities of any series shall be in
authorized denominations and substantially of the tenor of the definitive
Securities of that series in lieu of which they are issued, but may have
variations that the Company considers appropriate for temporary Securities. In
the case of Securities of any series, such temporary Securities may be in global
form. If temporary Securities of any series are issued, the Company will cause
definitive Securities of that series to be prepared without unreasonable delay.
After the preparation of definitive Securities of such series, and upon
surrender for cancellation of any one or more temporary Securities of such
series, the Company shall execute and the Trustee shall authen-


<PAGE>
                                      -20-


ticate and deliver in exchange therefor a like aggregate principal amount of
definitive Securities of authorized denominations of the same series and
containing identical terms and provisions. Until so exchanged, the temporary
Securities of any series shall, except as otherwise specified as contemplated by
Section 2.02 (including with respect to the payment of interest on temporary
Securities), in all respects be entitled to the same benefits under this
Indenture as definitive Securities of the same series and of like tenor
authenticated and delivered hereunder.

SECTION 2.12. Cancellation.

     The Company at any time may deliver Securities to the Trustee for
cancellation, including Securities authenticated which the Company has not
issued and sold. The Company and each Agent shall forward to the Trustee any
Securities surrendered to them for transfer, exchange, payment, redemption, or
purchase by the Company pursuant to any provision thereof providing for such
purchase at the option of the Holder. The Trustee and no one else shall cancel
all Securities surrendered for transfer, exchange, payment, redemption,
purchase, or cancellation, and may dispose of cancelled Securities as the
Company directs; provided, however, that the Trustee shall not be required to
destroy such cancelled Securities. Except as otherwise provided in the
resolution of the Board of Directors or indenture supplemental hereto
establishing such series as contemplated by Section 2.02, the Company may not
issue new Securities of a series to replace Securities of the same series that
it has paid or that have been delivered to the Trustee for cancellation.

SECTION 2.13. Payment of Interest; Defaulted Interest.

     Unless otherwise provided with respect to the Securities of any series as
contemplated by Section 2.02, interest (except defaulted interest) on any
Security of any series which is payable on any Interest Payment Date shall be
paid to the Holder in whose name that Security (or one or more Predecessor
Securities) is registered on the security register at the close of business on
the Regular Record Date for such interest payment. At the option of the Company,
payment of interest on any Security may be made (i) by check mailed to the
address of the Person entitled thereto as such address appears in the security
register, or (ii) if so specified with respect to the Securities of such series
as contemplated by Section 2.02, by wire transfer to any account designated by
such Person so long as


<PAGE>
                                      -21-


the Paying Agent is notified in writing at least five Business Days prior to
such Interest Payment Date.

     If the Company defaults in a payment of interest on the Securities of any
series on any Interest Payment Date, it shall pay the defaulted interest to the
Persons who are Securityholders of such series at the close of business on a
subsequent special record date. The Company shall fix the special record date
and payment date. At least 15 days before the record date, the Company shall
mail to each Securityholder of such series a notice that states the special
record date, the payment date and the amount of defaulted interest proposed to
be paid. The Company shall notify the Trustee in writing of the amount of the
defaulted interest proposed to be paid on each Security of such series and the
date of the proposed payment, and at the same time the Company shall deposit
with the Paying Agent an amount of money equal to the aggregate amount proposed
to be paid in respect of such defaulted interest or shall make arrangements
satisfactory to the Paying Agent for such deposit prior to the date of the
proposed payment. The Company may pay defaulted interest in any other lawful
manner.

SECTION 2.14. Persons Deemed Owners.

     Prior to due presentment of a Security for registration of transfer, the
Company, the Trustee and any Agent may treat the person in whose name such
Security is registered as the owner of such Security for the purpose of
receiving payment of principal of and (subject to Section 2.13) interest on such
Security and for all other purposes whatsoever, and neither the Company, the
Trustee nor any Agent shall be affected by notice to the contrary.

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

     Notwithstanding the foregoing, with respect to any global Security, nothing
herein shall prevent the Company, the


<PAGE>
                                      -22-


Trustee, or any Agent from giving effect to any written certification, proxy or
other authorization furnished by any depositary, as a Holder, with respect to
such global Security or impair, as between such depositary and owners of
beneficial interests in such global Security, the operation of customary
practices governing the exercise of the rights of such depositary (or its
nominee) as Holder of such global Security.

SECTION 2.15. Securities in Global Form.

     If the Company shall establish pursuant to Section 2.02 that the Securities
of or within a series are to be issued in whole or in part in global form, then
the Company shall execute, and the Trustee shall, in accordance with Section
2.04 and the written order of the Company contemplated thereby, authenticate and
deliver one or more global Securities in temporary or permanent form that (i)
shall be registered in the name of the depositary for such global Security or
Securities or the nominee of such depositary, (ii) shall be delivered by the
Trustee to such depositary or pursuant to such depositary's instructions, and
(iii) shall bear a legend substantially to the following effect: "Unless and
until it is exchanged in whole or in part for Securities in definitive form,
this Security may not be transferred except as a whole by the depositary to a
nominee of the depositary or another nominee of the depositary or by the
depositary or any such nominee to a successor depositary or a nominee of such
successor depositary." Each depositary designated pursuant to Section 2.02 for a
global Security in registered form must be, to the extent required by applicable
law or regulation, a clearing agency registered under the Securities Exchange
Act of 1934, as amended, and any other applicable statute or regulation, at the
time of its designation and at all times that it serves as depositary.
Notwithstanding clause (14) of Section 2.02 and the provisions of Section 2.03,
any such global Security shall represent such of the outstanding Securities of
such series as shall be specified therein and may provide that it shall
represent the aggregate amount of outstanding Securities of such series from
time to time endorsed thereon and that the aggregate amount of outstanding
Securities represented thereby may from time to time be increased or decreased
to reflect exchanges. Any endorsement of a Security in a global form to reflect
the amount, or any increase or decrease in the amount, or changes in the rights
of Holders, of outstanding Securities represented thereby shall be made in such
manner and upon instructions given by such Person or Persons as shall be
specified therein or in the written order of the Company to be delivered to the
Trustee pursuant to Section 2.04. Subject to


<PAGE>
                                      -23-


the provisions of Section 2.04 and, if applicable, Section 2.11, the Trustee
shall deliver and redeliver any Security in permanent global form in the manner
and upon instructions given by the Person or Persons specified therein or in the
applicable written order of the Company. If a written order of the Company
pursuant to Section 2.04 has been, or simultaneously is, delivered, any
instructions with respect to a Security in global form shall be in writing but
need not comply with Sections 11.04 and 11.05 and need not be accompanied by an
Opinion of Counsel.

     The provisions of the last sentence of the third paragraph of Section 2.04
shall apply to any Security represented by a Security in global form if such
Security was never issued and sold by the Company and the Company delivers to
the Trustee the Security in global form together with written instructions
(which need not comply with Sections 11.04 and 11.05 and need not be accompanied
by an Opinion of Counsel) with regard to the reduction in the principal amount
of Securities represented thereby, together with the written statement
contemplated by the last sentence of the third paragraph of Section 2.04.

SECTION 2.16. 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; provided, however, that 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 of any change in the "CUSIP" numbers.


                                  ARTICLE THREE

                                   REDEMPTION


SECTION 3.01. Applicability of Article.

     Securities of any series which are redeemable before their stated maturity
at the election of the Company or through


<PAGE>
                                      -24-


the operation of any sinking fund for the retirement of Securities of such
series shall be redeemable in accordance with their terms and (except as
otherwise specified as contemplated by Section 2.02 for Securities of any
series) in accordance with this Article.

SECTION 3.02. Notices to Trustee.

     If the Company elects to redeem all or less than all the Securities of any
series, it shall notify the Trustee of the redemption date, the principal amount
of Securities to be redeemed, the specific provision of the Securities pursuant
to which the Securities being called for redemption are being redeemed and the
redemption price. In the case of any redemption of Securities prior to the
expiration of any restriction on such redemption provided in the terms of such
Securities or elsewhere in this Indenture, the Company shall furnish the Trustee
with an Officers' Certificate evidencing compliance with such restriction. If
the Company wants to make any permitted optional sinking fund payment, it shall
notify the Trustee of the principal amount of the Securities to be redeemed.

     The Company (1) may deliver outstanding Securities of a series (other than
any previously called for redemption) and (2) may apply as a credit Securities
of a series which have been redeemed or otherwise purchased either at the
election of the Company pursuant to the terms of such Securities or through the
application of permitted optional sinking fund payments pursuant to the terms of
such Securities in satisfaction of all or any part of any sinking fund payment
required to be made pursuant to the terms of the Securities of such series as
provided for by the terms of such series: provided, however, that such
Securities have not been previously so credited. Such Securities shall be
received and credited for such purpose by the Trustee at the redemption price
specified in such Securities for redemption through operation of the sinking
fund and the amount of such sinking fund payment shall be reduced accordingly.
The Company shall notify the Trustee of its intention to so reduce the amount of
such sinking fund payment, the amount of the reduction and the basis for it. The
Company shall deliver to the Trustee with such notice any Securities to be
credited for such purpose that it has not previously delivered to the Trustee
for cancellation.

     The Company shall give each notice and Officers' Certificate provided for
in this Section at least 60 days before the redemption date (unless a shorter
notice shall be satisfac-


<PAGE>
                                      -25-


tory to the Trustee or is otherwise specified as contemplated by Section 2.02
for Securities of any series).

SECTION 3.03. Selection of Securities to be Redeemed.

     Except as otherwise specified as contemplated by Section 2.02 for
Securities of any series, if less than all the Securities of any series are to
be redeemed, the particular Securities to be redeemed shall be selected from
Securities of the same series outstanding not previously called for redemption
by such method as the Trustee considers fair and appropriate (and in such manner
as complies with applicable requirements of any stock exchange on which
Securities of such series 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 any integral multiple thereof) of the principal
amount of Securities of such series that have denominations larger than the
minimum authorized denomination for Securities of that series. Provisions of
this Indenture that apply to Securities called for redemption also apply to
portions of Securities called for redemption.

SECTION 3.04. Notice of Redemption.

     At least 30 days but no more than 60 days before a redemption date (unless
a shorter notice is specified as contemplated by Section 2.02 for Securities of
any series), the Company shall mail a notice of redemption by first-class mail
to each Holder of Securities of the series to be redeemed.

     The notice shall identify the Securities, including CUSIP number, if any
(and, in the case of partial redemption, the principal amount of the
Securities), to be redeemed and shall state:

          (1) The redemption date;

          (2) the redemption price and method of payment, if other than in cash;

          (3) the name and address of the Paying Agent;

          (4) that Securities called for redemption must be surrendered to the
     Paying Agent to collect the redemption price;

          (5) that interest, if any (or original issue discount, if Original
     Issue Discount Securities), on Securi-


<PAGE>
                                      -26-


     ties called for redemption ceases to accrue on and after the redemption
     date, unless the Company defaults in making such redemption payment; and

          (6) that the redemption is for a sinking fund or at the election of
     the Company, whichever is the case.

     At the Company's request, the Trustee shall give the notice of redemption
in the Company's name and at the Company's expense, provided that the Company
shall have furnished to the Trustee the Officers' Certificate and Opinion of
Counsel required pursuant to Section 11.04 at least 15 days prior to the date
that the Trustee is required to take any action in connection with a redemption.

SECTION 3.05. Effect of Notice of Redemption.

     Once notice of redemption is mailed, Securities of the series called for
redemption become due and payable on the redemption date and at the redemption
price therein specified and on and after such date (unless the Company shall
default in the payment of the redemption price and accrued interest, if any)
such Securities shall cease to bear interest, if any (and original issue
discount, if such Securities are Original Issue Discount Securities, shall cease
to accrue). Upon surrender to the Paying Agent, such Securities shall be paid at
the redemption price, plus, if applicable, accrued interest, if any, to the
redemption date: provided, however, that installments of interest the Interest
Payment Date for which is on or prior to the redemption date shall be payable to
the persons who are Holders of such Securities (or one or more Predecessor
Securities) on the relevant record dates for such interest according to their
terms and Section 2.13.

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

SECTION 3.06. Deposit of Redemption Price.

     On or before 10:00 a.m., New York time, on the redemption date, the Company
shall deposit with the Paying Agent money (or securities if permitted by the
terms of such Securities) sufficient to pay the redemption price of, and (except
if the redemption date is an Interest Payment Date) accrued interest, if any,
on, all Securities to be redeemed on that date other than Securities or portions
thereof called for redemption


<PAGE>
                                      -27-


on that date which are delivered by the Company to the Trustee for cancellation.

SECTION 3.07. Securities Redeemed in Part.

     Any Security that is to be redeemed only in part shall be surrendered at a
place of payment therefor (with, if the Company, the Registrar or the Trustee so
requires, due endorsement by, or a written instrument of transfer in form
satisfactory to the Company, the Registrar and the Trustee duly executed by, the
Holder thereof or his attorney duly authorized in writing), and the Company
shall execute, and the Trustee shall authenticate and deliver to the Holder of
such Security without service charge, a new Security or Securities of the same
series, containing identical terms and provisions, of any authorized
denomination as requested by such Holder in aggregate principal amount equal to
and in exchange for the unredeemed portion of the principal amount of the
Security so surrendered, and, unless otherwise specified as contemplated by
Section 2.02, if a global Security is so surrendered, the Company shall execute,
and the Trustee shall authenticate and deliver to the depositary for such global
Security, without service charge, a new global Security in a denomination equal
to and in exchange for the unredeemed portion of the principal amount of the
global Security so surrendered.

SECTION 4.01. Payment of Securities.

     The Company shall pay the principal of and any interest on the Securities
of each series in accordance with the terms of the Securities of such series and
this Indenture.

     To the extent enforceable under applicable law, the Company shall pay
interest on overdue principal at the rate borne by the Securities of such series
(unless a different rate is specified as contemplated by Section 2.02 for
Securities of such series).

SECTION 4.02. SEC Reports.

     The Company shall file with the Trustee within 15 days after it files them
with the SEC copies of the annual re-


<PAGE>
                                      -28-


ports and of the information, documents and other reports (or copies of such
portions of any of the foregoing as the SEC may by rules and regulations
prescribe) which the Company is required to file with the SEC pursuant to
Section 13 or 15(d) of the Securities Exchange Act of 1934. The Company also
shall comply with the other provisions of TIA ss.314(a).

SECTION 4.03. Compliance Certificate.

     The Company shall deliver to the Trustee within 120 days after the end of
each fiscal year of the Company an Officers' Certificate stating whether or not
the signers know of the existence of any default or Event of Default by the
Company and whether all of the conditions and covenants of the Company are being
complied with regardless of any period of grace or requirement of notice
provided under this Indenture. If they do know of such a default or Event of
Default, the certificate shall describe the default or Event of Default, as the
case may be, and its status. The first Officers' Certificate to be delivered
pursuant to this Section 4.03 shall be for the fiscal year ending immediately
after the date that the Securities are issued.

SECTION 4.04. Corporate Existence.

     Subject to the provisions of Section 5.01, the Company will do or cause to
be done all things necessary to preserve and keep in full force and effect its
corporate existence.

SECTION 4.05. Calculation of Original Issue Discount.

     The Company shall file with the Trustee promptly at the end of each
calendar year a written notice specifying the amount of original issue discount
(including daily rates and accrual periods), if any, accrued on outstanding
Securities as of the end of such year.

tirety to, another corporation unless (1) either XL Capital is the successor,
or, if XL Capital is not the surviving Person, the surviving Person assumes by
supplemental indenture all the obligations of the Company under the Securities
and this Indenture; and (2) immediately after giving effect to such transaction,
no Event of Default shall have occurred and be continuing. Thereafter, unless
otherwise specified as contemplated by Section 2.02 for the Securities of any
series, all such obligations of the predecessor corporation shall terminate.

                              DEFAULTS AND REMEDIES


SECTION 6.01. Events of Default.

     An "Event of Default" with respect to Securities of any series means each
of the events specified below in this Section 6.01, unless it is either
inapplicable to a particular series or is specifically deleted or modified as
contemplated by Section 2.02 for the Securities of such series, and any other
events as may be specified as contemplated by Section 2.02 for the Securities of
such series:

          (1) the Company defaults in the payment of any interest on any
     Security of that series when the same becomes due and payable and the
     default continues for a period of 60 days;

          (2) the Company defaults in the payment of the principal of any
     Security of that series when the same becomes due and payable at maturity,
     upon redemption (including default in the making of any mandatory sinking
     fund payment), upon purchase by the Company at the option of the Holder
     pursuant to the terms of such Security or otherwise;

          (3) the Company fails to comply with any of its other agreements in
     Securities of that series or this Indenture (other than an agreement which
     has expressly been included in this Indenture solely for the benefit of
     Securities of any series other than that series or is expressly made
     inapplicable to the Securities of such series as contemplated by Section
     2.02) and the default continues for the period and after the notice
     specified below;


<PAGE>
                                      -30-


          (4) the Company pursuant to or within the meaning of any Bankruptcy
     Law:

               (A) commences a voluntary case, or consents to the commencement
          of a case against it,

               (B) consents to the entry of an order for relief against it in an
          involuntary case, (C) consents to the appointment of a Custodian of it
          or for all or substantially all of its property, or

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

          (5) a court of competent jurisdiction enters an order or decree under
     any Bankruptcy Law that:

               (A) is for relief against the Company in an involuntary case or
          adjudicates the Company insolvent or bankrupt,

               (B) appoints a Custodian of the Company or for all or
          substantially all of its property, or

               (C) orders the winding up or liquidation of the Company, and the
          order or decree remains unstayed and in effect for 90 days; or

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

     The term "Bankruptcy Law" means Title 11, U.S. Code or any similar Federal
or State law for the relief of debtors. The term "Custodian" means any receiver,
trustee, assignee, liquidator or similar official under any Bankruptcy Law.

     A default under clause (3) is not an Event of Default until the Trustee
notifies the Company or the Holders of at least 25% in aggregate principal
amount of the outstanding Securities of that series notify the Company and the
Trustee of the default and the Company does not cure the default within 90 days
after receipt of the notice. The notice must specify the default, demand that it
be remedied and state that the notice is a "Notice of Default."


<PAGE>
                                      -31-


SECTION 6.02. Acceleration.

     If an Event of Default (other than an Event of Default specified in Section
6.01(4) or (5)) occurs and is continuing with respect to Securities of any
series at the time outstanding, the Trustee by notice to the Company, or the
Holders of at least 25% in aggregate principal amount of the outstanding
Securities of that series by notice to the Company and the Trustee, may declare
to be due and payable immediately (1) the principal amount (or, if the
Securities of that series are Original Issue Discount Securities, such portion
of the principal amount as may be specified in the terms of the Securities of
that series) of all of the Securities of that series then outstanding and (2)
interest, if any, accrued to the date of acceleration. Upon such declaration,
such principal amount (or specified amount) and interest, if any, shall be due
and payable immediately. If an Event of Default specified in Section 6.01 (4) or
(5) occurs and is continuing, (1) the principal amount (or, if the Securities of
that series are Original Issue Discount Securities, such portion of the
principal amount as may be specified in the terms of the Securities of that
series) of all of the Securities of that series then outstanding and (2)
interest, if any, accrued to the date of such acceleration shall become and be
immediately due and payable without any declaration or other act on the part of
the Trustee or Securityholders. The Holders of a majority in aggregate principal
amount of the outstanding Securities of the series with respect to which an
acceleration applies by notice to the Trustee may rescind an acceleration and
its consequences with respect to such series if all existing Events of Default
(other than the non-payment of the principal of and accrued interest, if any, on
Securities that have become due solely by such acceleration) with respect to
Securities of that series have been cured or waived and if the rescission would
not conflict with any judgment or decree. No such rescission shall affect any
subsequent default or impair any right consequence thereon.

SECTION 6.03. Other Remedies.

     If an Event of Default with respect to Securities of any series occurs and
is continuing, the Trustee may pursue any available remedy by proceeding at law
or in equity to collect the payment of the whole amount which then shall have
become due and remain unpaid for principal or interest, if any, on the
Securities of that series or to enforce the performance of any provision of the
Securities of that series or this Indenture.


<PAGE>
                                      -32-


     The Trustee may maintain a proceeding even if it does not possess any of
the Securities of that series or does not produce any of them in the proceeding.
A delay or omission by the Trustee or any Securityholder in exercising any right
or remedy accruing upon an Event of Default shall not impair the right or remedy
or constitute a waiver or acquiescence in the Event of Default. No remedy is
exclusive of any other remedy. All available remedies are cumulative.

SECTION 6.04. Waiver of Existing Defaults.

     Subject to Section 9.02, the Holders of a majority in aggregate principal
amount of the outstanding Securities of any series by notice to the Trustee may
waive on behalf of the Holders of all the Securities of such series an existing
Default or Event of Default and its consequences. When a Default or Event of
Default is waived, it is cured and stops continuing.

SECTION 6.05. Control by Majority.

     The Holders of a majority in aggregate principal amount of the outstanding
Securities of any series may 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 it, with respect to the Securities of such series. The
Trustee, however, may refuse to follow any direction that conflicts with law or
this Indenture, that is unduly prejudicial to the rights of another
Securityholder or that would involve the Trustee in personal liability.

SECTION 6.06. Limitation of Suits.

     No Holder of any Security of any series shall have the right to pursue any
remedy with respect to this Indenture or the Securities unless:

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

          (2) the Holders of at least 25% in aggregate principal amount of the
     outstanding Securities of that series in respect of which the Event of
     Default has occurred make a written request to the Trustee to pursue the
     remedy;


<PAGE>
                                      -33-


          (3) such Holder or Holders offer and provide to the Trustee indemnity
     satisfactory to the Trustee against any loss, liability or expense;

          (4) the Trustee does not comply with the request within 60 days after
     receipt of the request and the offer of indemnity; and

          (5) no direction inconsistent with such written request has been given
     to the Trustee during such 60-day period by the Holders of a majority in
     aggregate principal amount of the outstanding Securities of such series.

     A Securityholder of any series may not use this Indenture to prejudice the
rights of another Securityholder of such series or to obtain a preference or
priority over another Securityholder of such series, except in the manner herein
provided and for the equal and ratable benefit of all Securityholders of such
series.

SECTION 6.07. Rights of Holders to Receive Payment and to Convert.

     Subject to the terms of the Securities of any series relating to
subordination (as contemplated by Article Ten and Section 2.02) and
notwithstanding any other provision of this Indenture, the right of any Holder
of a Security to receive payment of principal of and (subject to Section 2.13)
interest, if any, on the Security, on or after the respective due dates with
respect to such payments expressed in such Security, and, if applicable, to
convert such Security on the terms and subject to the conditions applicable to
Securities of such series, or to bring suit for the enforcement of any such
payment on or after such respective dates or of such right to convert, if any,
shall not be impaired or affected without the consent of the Holder.

SECTION 6.08. Collection Suit by Trustee.

     If an Event of Default specified in Section 6.01(1) or (2) occurs and is
continuing with respect to the Securities of any series, the Trustee may recover
judgment in its own name and as trustee of an express trust against the Company
for the whole amount which then shall have become due and remain unpaid for
principal and interest, if any, on the Securities of such series.

                                      -34-


SECTION 6.09. Trustee May File Proofs of Claim.

     The Trustee may file such proofs of claim and other papers or documents as
may be necessary or advisable in order to have the claims of the Trustee and the
Securityholders allowed in any judicial proceedings relative to the Company, its
creditors or its property and to collect and receive money, property or
securities payable or deliverable on any such claims and to distribute the same.

its appointed capacities pursuant to this Indenture unless any provision
specifically applies to the Trustee only in its capacity as Trustee.

SECTION 7.01. Duties of Trustee.

     (a) If an Event of Default with respect to Securities of any series has
occurred and is continuing, the Trustee shall with respect to such series
exercise such of the rights and powers vested in it by this Indenture with
respect to such series 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.

     set forth in this Indenture or the TIA and no others.

          (2) In the absence of bad faith on its part, the Trustee may
     conclusively rely, as to the truth of the statements and the correctness of
     the opinions expressed therein, upon certificates or opinions furnished to
     the Trustee and conforming to the requirements of this Indenture. The
     Trustee, however, shall, with respect to certificates or opinions which by
     any provision hereof are required to be provided to the Trustee, examine
     the certificates and opinions to determine whether or not they conform to
     the requirements of this Indenture (but need not confirm or investigate the
     accuracy of mathematical calculations or other facts stated therein).


<PAGE>

trust by the Trustee need not be segregated from other funds except to the

     (g) No provision of this Indenture shall require the Trustee to expend or
risk its own funds or otherwise incur any financial liability in the performance
of any of its duties hereunder, or in the exercise of any of its rights or
powers, if it shall have reasonable grounds for believing that repayment of such
funds or adequate indemnity against such risk or liability is not reasonably
assured to it.

SECTION 7.02. Rights of Trustee.

genuine and to have been signed or presented by the proper Person. The Trustee
need not investigate any fact or matter stated in the document.

counsel of its selection or require an Of-

sufficiently evidenced by a Company Request or Company Order and any resolution
of the Board of Directors may be sufficiently evidenced by a Board Resolution.

     (f) The Trustee shall not be deemed to have notice of any Default or Event

notice references the Securities and this Indenture.

SECTION 7.03. Individual Rights of Trustee.

     The Trustee in its individual or any other capacity may become the owner or
pledgee of Securities and may otherwise deal with the Company or its Affiliates

same with like rights. The Trustee, however, must comply with Sections 7.10 and
7.11.

SECTION 7.04. Trustee's Disclaimer.

authentication.

SECTION 7.05. Notice of Defaults.

     If a Default occurs and is continuing with respect to Securities of any
series and if it is actually known to a Trust


<PAGE>
                                      -38-


Officer of the Trustee, the Trustee shall transmit by mail to each
Securityholder or such series in the manner and to the extent provided in TIA
ss. 313(c) notice of the Default within 90 days after its occurs or as soon as
reasonably practicable thereafter. Except in the case of a default in payment of
principal of or interest on any Security of such series (including default in
the making of any mandatory sinking fund or mandatory repurchase payment), the
Trustee may withhold the notice if and so long as a committee of its Trust
Officers in good faith determines that withholding the notice is in the
interests of Securityholders of such series.

SECTION 7.06. Reports by Trustee to Holders.

     Within 60 days after each May 15 beginning with the May 15 following the
date on which Securities are originally issued under this Indenture, the Trustee
shall transmit by mail to each Securityholder in the manner and to the extent
provided in TIA ss. 313(c) a brief report dated as of such May 15 that complies
with TIA ss. 313(a) if such report is required by TIA ss. 313(a). The Trustee
also shall comply with TIA ss. 313(b).

     A copy of each report at the time of its mailing to Securityholders shall
be filed by the Company with the SEC and each stock exchange on which the
Securities are listed.

     The Company will promptly notify the Trustee if and when the Securities of
any series are listed on any stock exchange.

SECTION 7.07. Compensation and Indemnity.

shall be agreed upon in a writing between the Company and the Trustee. The
Trustee's compensation shall not be limited by any law on compensation of a
trustee of an express trust. The Company shall reimburse the Trustee upon
request for all reasonable out-of-pocket expenses incurred by it. Such expenses
shall include the reasonable compensation and expenses of the Trustee's agents
and counsel.

     The Company shall indemnify the Trustee or any predecessor Trustee and
their agents for and to hold them harmless against any loss, damages, claims,
expenses or liability incurred by it arising out of or in connection with the
acceptance or administration of this trust and its duties hereunder. The Trustee
shall notify the Company promptly of any claims asserted against the Trustee for
which it may seek indemnity.


<PAGE>
                                      -39-


Failure of the Trustee to so notify the Company shall not relieve the Company of
its obligations hereunder. The Company shall have the right to elect to defend
the claim and the Trustee shall cooperate in the defense. The Trustee may have
separate counsel and the Company shall pay the reasonable fees and expenses of
such counsel. The Company need not pay for any settlement made without its
written consent, which consent shall not be unreasonably withheld. The Company
need not reimburse any expense or indemnify against any loss or liability
incurred by the Trustee through negligence or bad faith.

     To secure the Company's payment obligations in this Section, the Trustee
shall have a lien prior to the Securities on all money or property held or
collected by the Trustee, except that held in trust to pay principal of or
interest on particular Securities.

     When the Trustee incurs expenses or renders services after an Event of
Default specified in Section 6.01(4) or (5) occurs, the expenses and the
compensation for the services are intended to constitute expenses of
administration under any Bankruptcy Law.

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

SECTION 7.08. Replacement of Trustee.

     The Trustee may resign at any time with respect to Securities of one or
more series by so notifying the Company. The Holders of a majority in aggregate
principal amount of the outstanding Securities of any series may remove the
Trustee with respect to the Securities of such series by so notifying the
removed Trustee and may appoint a successor Trustee with the Company's consent.
The Company shall remove the Trustee if:

          (1) the Trustee fails to comply with Section 7.10;

          (2) the Trustee is adjudged a bankrupt or an insolvent;

          (3) a receiver or other public officer takes charge of the Trustee or
     its property; or

          (4) the Trustee becomes incapable of acting.


<PAGE>
                                      -40-


     If the Trustee resigns or is removed, or if a vacancy exists in the office
of the Trustee for any reason, with respect to the Securities of one or more
series, the Company shall promptly appoint a successor Trustee or Trustees (it
being understood that any such successor Trustee may be appointed with respect
to the Securities of one or more or all of such series and that at any time
there shall be only one Trustee with respect to the Securities of any particular
series).

     A successor Trustee shall deliver a written acceptance of its appointment
to the retiring Trustee and to the Company. Immediately after that, the retiring
Trustee shall transfer all property held by it as Trustee to the successor
Trustee (subject to its lien, if any, provided for in Section 7.07), the
resignation or removal of the retiring Trustee shall become effective, and the
successor Trustee shall have all the rights, powers and duties of the Trustee
under this Indenture. A successor Trustee shall mail notice of its succession to
each Securityholder.

     If a successor Trustee with respect to Securities of any series does not
take office within 30 days after the retiring Trustee resigns or is removed, the
retiring Trustee (at the expense of the Company), the Company or the Holders of
a majority in aggregate principal amount of the outstanding Securities of such
series may petition any court of competent jurisdiction for the appointment of a
successor Trustee.

     If the Trustee fails to comply with Section 7.10, any Securityholder may
petition any court of competent jurisdiction for the removal of the Trustee with
respect to all Securities and the appointment of a successor Trustee.

SECTION 7.09. Successor Trustee by Merger, etc.

     If the Trustee consolidates with, mergers or converts into, or transfers
all or substantially all of its corporate trust assets to (including the
administration of this Indenture), another corporation or national banking
association, the successor corporation or national banking association without
any further act shall be the successor Trustee.

SECTION 7.10. Eligibility; Disqualification.

     This Indenture shall always have a Trustee who satisfies the requirements
of TIA ss. 310(a). The Trustee shall always have (or in the case of a subsidiary
of a bank holding company that guarantees the obligations of the Trustee under
this Indenture, such holding company parent shall have) a combined capital and
surplus of at least $50,000,000 as set forth in its most recent published annual
report of condition. With respect to the Securities of each


<PAGE>
                                      -41-


series, the Trustee shall comply with TIA ss. 310(b). In determining whether the
Trustee has a conflicting interest as defined in TIA ss. 310(b) with respect to
the Securities of any series, there shall be excluded this Indenture with
respect to the Securities of any series other than that series. Nothing herein
shall prevent the Trustee from filing with the SEC the application referred to
in the second to last paragraph of TIA ss. 310(b).

SECTION 7.11. Preferential Collection of Claims Against Company.

     The Trustee shall comply with TIA ss. 311(a), excluding any creditor
relationship listed in TIA ss. 311(b). A Trustee who has resigned or been

SECTION 7.12. Trustee's Application for Instructions from the Company.

     Any application by the Trustee for written instructions from the Company
may, at the option of the Trustee, set forth in writing any action proposed to
be taken or omitted by the Trustee under this Indenture and the date on and/or
after which such action shall be taken or such omission shall be effective. The
Trustee shall not be liable for any action taken by, or omission of, the Trustee
in accordance with a proposal included in such application on or after the date
specified in such application (which date shall not be less than three Business
Days after the date any officer of the Company actually receives such
application, unless any such officer shall have consented in writing to any
earlier date) unless prior to taking any such action (or the effective date in
the case of an omission), the Trustee shall have received written instructions
in response to such application specifying the action to be taken or omitted.

                             DISCHARGE OF INDENTURE


SECTION 8.01. Termination of Company's Obligations.

     The Company may terminate all of its obligations under the Securities of

rities of such series previously authenticated and delivered (other than
destroyed, lost or stolen Securities which have been replaced or paid or
Securities for whose payment money (or, if permitted by the terms of such
Securities, securities) has theretofore been held in trust and thereafter repaid
to the Company, as provided in Section 8.03) have been delivered to the Trustee
for cancellation; or (2) (i) the Company irrevocably deposits in trust with the

7.07, 7.08 and 8.03 of this Indenture, however, shall survive until the
Securities of such series are no longer outstanding. Thereafter, the Company's
obligations in Sections 7.07 and 8.03 shall survive. Notwithstanding the
satisfaction and discharge of this Indenture with respect to the Securities of
any series, if money or U.S. Government Obligations shall have been deposited
with the Trustee pursuant to clause (2) of the first paragraph of this Section,
the obligations of the Trustee under Section 8.02 and the second sentence of
Section 8.03 shall survive.

     After a deposit and if all other conditions thereto are met, the Trustee
for the Securities of such series shall be required to execute an instrument
acknowledging satisfaction and discharge of this Indenture with respect to such
Securities, except for those surviving obligations specified above; provided,
however, that the Trustee shall not be required to execute such instrument until
the expiration of 90 days after the date of a deposit and that such instrument
may be made subject to the condition that such deposit had been in compliance

                                      -43-

amounts as will provide the necessary money. U.S. Government Obligations shall
not be callable at the issuer's option.

SECTION 8.02. Application of Trust Fund.

     The Trustee shall hold in trust money and U.S. Government Obligations
deposited with it pursuant to Section 8.01. Subject to any applicable terms of
the Securities of any series relating to subordination (as contemplated by

the money from the U.S. Government Obligations through the Paying Agent and in
accordance with the provisions of the Securities of such series and this
Indenture to the payment of principal of and interest, if any, on the Securities
of such series for the payment of which such money or U.S. Government
Obligations has been deposited with the Trustee.

     The Company shall pay and indemnify the Trustee against any tax, fee or
other charge imposed on or assessed against the U.S. Government Obligations
deposited pursuant to Section 8.01 or the principal and interest received in
respect thereof other than any such tax, fee or other charge which by law is for
the account of the Holders of outstanding Securities.

SECTION 9.01. Without Consent of Holders.

     The Company and the Trustee may amend or supplement this Indenture or the
Securities of any series without notice to or consent of any Securityholder:

          (1) to cure any ambiguity, defect or inconsistency;

          (2) to comply with Section 5.01;

          (3) to establish the form or terms of Securities of any series as
     permitted by Sections 2.01 and 2.02;

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

          (5) to add any additional Events of Default (and if such Events of
     Default are to be applicable to less than all series of Securities, stating
     that such Events of Default are expressly being included solely to be
     applicable to such series);

          (6) to change or eliminate any of the provisions of this Indenture,
     provided that, except as otherwise contemplated by Section 2.02(14), any
     such change or elimination shall become effective only when there is no
     Security outstanding of any series created prior thereto which is entitled
     to the benefit of such provision;

          (7) to add or change any of the provisions of this Indenture to such
     extent as shall be necessary to permit or facilitate the issuance of
     Securities in bearer form, registrable or not registrable as to principal,
     and with or without interest coupons, or to provide for uncertificated
     Securities in addition to certificated Securities (so long as any

supplement. The Holders of a majority in aggregate principal amount of the
outstanding Securities of any series may on behalf of the Holders of all
Securities of such series waive compliance by the Company with any provision of
this Indenture or of Securities of such series without notice to any
Securityholder. Without the consent of each Securityholder affected, however,
the amendment, supplement or waiver, including a waiver pursuant to Section
6.04, may not:

          (1) reduce the amount of Securities of any series whose Holders must
     consent to an amendment, supplement or waiver;

          (2) reduce the rate of or extend the time for payment of interest on
     any Security (or, in the case of an Original Issue Discount Security,
     reduce the rate of accrual of original issue discount);

          (3) reduce the principal of (or any premium payable upon the
     redemption of) or change the fixed maturity of any Security (or, in the
     case of an Original Issue Discount Security, reduce the portion of the
     principal amount that would be due and payable upon acceleration of the
     maturity thereof pursuant to Section 6.02);

          (4) change the amount or time of any payment required by any sinking
     fund provisions of the Securities of any series;

          (5) make any change that materially adversely affects the rights of a
     Holder to require the Company to


<PAGE>
                                      -46-


     purchase a Security in accordance with the terms thereof and this
     Indenture;

          (6) waive a default in the payment of the principal of or interest, if
     any, on any Security; or

          (7) make any Security payable in money or securities other than that
     stated in the Security.

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

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

SECTION 9.03. Compliance with the Trust Indenture Act.

     Every amendment to or supplement of this Indenture or the Securities shall
comply with the TIA as then in effect.

SECTION 9.04. Revocation and Effect of Consents.

     A consent to an amendment, supplement, waiver or other action by a Holder
of a Security shall bind the Holder and every subsequent Holder of a Security or
portion of a Security that evidences the same debt as the consenting Holder's
Security, even if notation of the consent is not made on any Security. Any such
Holder or subsequent Holder, however, may revoke the consent as to his Security
or portion of a Security. Such revocation shall be effective only if the Trustee
receives the notice of revocation before the date the amendment, supplement,
waiver or other action becomes effective. An amendment, supplement, waiver or
other action shall become effective on receipt by the Trustee of written
consents from the Holders of the requisite percentage in aggregate principal
amount of the outstanding Securities of the relevant series. After an amendment,
supplement or waiver becomes effective, it shall bind every Securityholder of
each series of Securities so affected.

SECTION 9.05. Notation on or Exchange of Securities.

     If an amendment, supplement or waiver changes the terms of a Security, the
Trustee may require the Holder of the Security to deliver it to the Trustee. The
Trustee may place an appropriate notation on the Security about the changed
terms and return it to the Holder. Alternatively, if the Company or the Trustee
so determines, the Company in exchange for the Security shall issue and the
Trustee shall authenticate a new Security that reflects the changed terms.

SECTION 9.06. Trustee to Sign Amendments, etc.

     The Trustee shall sign any amendment, supplement or waiver authorized
pursuant to this Article if the amendment, supplement or waiver does not
adversely affect the rights, duties, immunities or liabilities of the Trustee.
If it does, the Trustee may but need not sign it. The Company may not sign an
amendment or supplement until the Board of Directors approves it.

     In executing, or accepting the additional trusts created by, any
supplemental indenture permitted by this Article or the modification thereby of
the trusts created by this Indenture, the Trustee shall be entitled to receive,
and shall be fully protected in relying upon, an Opinion of Counsel stating that
the execution of such supplemental indenture is authorized or permitted by this
Indenture.

him by first-class mail, postage prepaid, at his address as it appears on the

with respect to other Securityholders. Except for a notice to the Trustee, which
is deemed given only when received, if a notice or communication is mailed in
the manner provided above, it is duly given, whether or not the addressee
receives it.

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

SECTION 11.03. Communication by Holders with Other Holders.

     Securityholders may communicate pursuant to TIA ss. 312(b) with other
Securityholders with respect to their rights under this Indenture or the

     Upon any request or application by the Company to the Trustee to take any
action under this Indenture, the Company shall furnish to the Trustee:

          (1) an Officers' Certificate stating that, in the opinion of the
     signers, all conditions precedent (including any covenants compliance with
     which constitutes a condition precedent), if any, provided for in this
     Indenture relating to the proposed action have been complied with; and

          (2) 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.

SECTION 11.05. Statements Required in Certificate or Opinion.

     Each Officers' Certificate or Opinion of Counsel with respect to compliance
with a condition or covenant provided for in this Indenture (other than
certificates provided pursuant to Section 4.03) shall include:

                                      -50-


          (1) a statement that the person making such certificate or opinion has
     read such covenant or condition;

          (2) a brief 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;

          (3) 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

          (4) a statement as to whether or not, in the opinion of such person,
     such condition or covenant has been complied with.

SECTION 11.06. When Treasury Securities Disregarded.

     In determining whether the Holders of the required aggregate principal
amount of Securities of any series have concurred in any direction, waiver or
consent, Securities of such series owned by the Company or by any Affiliate of
the Company shall be disregarded and treated as not outstanding, except that for
the purposes of determining whether the Trustee shall be protected in relying on
any such direction, waiver or consent, only Securities of such series which the
Trustee actually knows are so owned shall be so disregarded.

SECTION 11.07. Rules by Trustee and Agents.

     The Trustee may make reasonable rules for action by or a meeting of the
Securityholders of all series or any series. The Registrar and Paying Agent may
make reasonable rules for its functions.

SECTION 11.08. Legal Holidays.

     A "Legal Holiday" is a Saturday, a Sunday, or a day on which banking
institutions in the City of New York, New York or in Boston, Massachusetts or
any place of payment, are not required to be open. If a specified date
(including a date for giving notice) is a Legal Holiday, any action to be taken
on such date pursuant to this Indenture or the Securities (including such
conversion) may be taken on the next succeeding day that is not a Legal Holiday,
and, to the extent applicable, no interest, or original issue discount, as the
case may be, shall accrue for the intervening period.

     The internal laws of the State of New York shall govern this Indenture and
the Securities.

SECTION 11.10. No Adverse Interpretation of Other Agreements.

agreement of the Company or a Subsidiary. Any such indenture, loan or debt
agreement may not be used to interpret this Indenture.

SECTION 11.11. No Recourse Against Others.

     No past, present or future director, officer, employee or stockholder, as
such, of the Company or the Trustee or any successor of either thereof shall
have any liability for any obligations of the Company or the Trustee under the
Securities or this Indenture or for any claim based on, in respect of, or by
reason of, such obligations or their creation and all such liability is hereby
waived and released. Such waiver and release are part of the consideration for
the issue of the Securities.

SECTION 11.12. Successors.

     All agreements of the Company in this Indenture and the Securities shall
bind its successor. All agreements of the Trustee in this Indenture shall bind
its successor.

SECTION 11.13. Duplicate Originals.

     The parties may sign any number of copies of this Indenture. Each signed
copy shall be an original, but all of them together represent the same
agreement.

SECTION 11.14. Table of Contents, Headings, Etc.

     The table of contents and the titles and headings of the Articles and
Sections of this Indenture have been inserted for convenience of reference only,

SECTION 11.15. Acts of Holders.

     (a) Any direction, consent, waiver or other action provided by this
Indenture to be given or taken by Holders may be embodied in and evidenced by
one or more instruments of substantially similar tenor signed by such Holders in
person or by an agent duly appointed in writing. Except as herein otherwise
expressly provided, such action shall become effective when such instrument or
instruments are delivered to the Trustee and, where it is hereby expressly
required, to the Company. Proof of execution of any such instrument or of a
writing appointing any such agent, or of the holding by any person of a
Security, shall be sufficient for any purpose of this Indenture and (subject to
Section 7.01) conclusive in favor of the Trustee, the Company and any Agent, if
made in the manner provided in this Section.

     (b) The fact and date of the execution by any Person of any such instrument
may be proved by the affidavit of a witness of such execution or by a
certificate of a notary public or other officer authorized by law to take
acknowledgments of deeds. Where such execution is by a signer acting in a
capacity other than his individual capacity, such certificate or affidavit shall
also constitute sufficient proof of his authority. The fact and date of the
execution of any such instrument, or the authority of the Person executing the
same, may also be proved in any other manner which the Trustee deems sufficient.

     (c) The ownership, principal amount and serial numbers of outstanding
Securities held by any person, and the date of holding the same, shall be
provided by the security register.

     (d) If the Company shall solicit from the Holders of any Securities any
direction, consent, waiver or other authorization, the Company may at its option
(but is not obligated to), by or pursuant to a resolution of the Board of
Directors, fix in advance a record date for the determination of Holders of
Securities entitled to give such direction, consent, waiver or other
authorization. Notwithstanding TIA ss. 316(c), such record date shall be the
record date specified in or pursuant to such resolution of the Board of
Directors, which shall be a date not earlier than 30 days prior to the first
solicitation of Holders generally in connection therewith and not later than the
date such solicitation is completed. If such a record date is fixed, such
direction, consent, waiver or other authorization may be given before or after
such record date, but only


<PAGE>
                                      -53-


the Holders of Securities of record at the close of business on such record date
shall be deemed to be Holders for the purpose of determining whether Holders of
the requisite proportion of outstanding Securities have authorized or agreed or
consented to such direction, consent, waiver or other authorization, and for
that purpose the outstanding Securities shall be computed as of such record
date; provided that no such consent or other authorization by the Holders shall
be deemed effective unless it shall become effective pursuant to the provisions
of this Indenture not later than eleven months after the record date.

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

SECTION 11.16. Assignment.

     The Company shall have the right at all times to assign any to its rights
or obligations under this Indenture to a direct or indirect wholly owned
Subsidiary of the Company; provided, however, that, in the event of any such
assignment, the Company shall remain liable for all such obligations.
