     SECTION 2.04.  Authentication and Delivery of Subordinated Indentures.
                    ------------------------------------------------------

          At any time and from time to time after the execution and delivery of
this Subordinated Indenture, the Company may deliver any series of Subordinated
Securities having attached thereto appropriate Coupons, if any, executed by the
Company to the Trustee for authentication by it together with the applicable
documents referred to below in this Section 2.04, and the Trustee shall
thereupon authenticate and deliver said Subordinated Securities (or if only a
single Subordinated Security, such Subordinated Security) and Coupons, if any,
to or upon the written order of the Company, signed by an officer of the
Company, without any further corporate action.  The maturity date, original
issue date, interest rate and any other terms of the Subordinated Securities of
such series and Coupons, if any, appertaining thereto shall be determined by or
pursuant to such Company Order and procedures.  If provided for in such
procedures, such Company Order may authorize authentication and delivery
pursuant to oral or electronic instructions from the Company or its duly
authorized agent or agents, which instructions, if oral, shall be promptly
confirmed in writing.  In authenticating such Subordinated Securities and
accepting the additional responsibilities under this Subordinated Indenture in
relation to such Subordinated Securities, the Trustee shall be entitled to
receive (in the case of subparagraphs (2), (3) and (4) below only at or before
the time of the first request of the Company to the Trustee to authenticate
Subordinated Securities of such series) and (subject to Section 7.01) shall be
fully protected in relying upon, the following enumerated documents unless and
until such documents have been superseded or revoked:

          (1) a Company Order requesting such authentication and setting forth
delivery instructions if the Subordinated Securities and Coupons, if any, are
not to be delivered to the Company, provided that, with respect to Subordinated
Securities of a series subject to a Periodic Offering, (a) such Company Order
may be delivered by the Company to the Trustee prior to the delivery to the
Trustee of such Subordinated Securities for authentication and delivery, (b) the
Trustee shall authenticate and deliver Subordinated Securities of such series
for original issue from time to time, in an aggregate principal amount not
exceeding the aggregate principal

                                       11
<PAGE>

amount established for such series, pursuant to a Company Order or pursuant to
procedures acceptable to the Trustee as may be specified from time to time by a
Company Order, (c) the maturity date or dates, original issue date or dates,
interest rate or rates and any other terms of Subordinated Securities of such
series shall be determined by a Company Order or pursuant to such procedures and
(d) if provided for in such procedures, such Company Order may authorize
authentication and delivery pursuant to oral or electronic instructions from the
Company or its duly authorized agent or agents, which instructions, if oral,
shall be promptly confirmed in writing;

          (2) any Board Resolution, Officer's Certificate and/or executed
Supplemental Subordinated Indenture referred to in Section 2.01 and 2.03 by or
pursuant to which the forms and terms of the Subordinated Securities and
Coupons, if any, were established;

          (3) an Officer's Certificate setting forth the form or forms and terms
of the Subordinated Securities and Coupons, if any, stating that the form or
forms and terms of the Subordinated Securities and Coupons, if any, have been
established pursuant to Sections 2.01 and 2.03 and comply with this Subordinated
Indenture, and covering such other matters as the Trustee may reasonably
request; and

          (4) At the option of the Company, either one or more Opinions of
Counsel, or a letter addressed to the Trustee permitting it to rely on one or
more Opinions of Counsel, substantially to the effect that:

              (a) the form or forms of the Subordinated Securities and Coupons,
if any, have been duly authorized and established in conformity with the
provisions of this Subordinated Indenture;

              (b) in the case of an underwritten offering, the terms of the
Subordinated Securities have been duly authorized and established in conformity
with the provisions of this Subordinated Indenture, and, in the case of an
offering that is not underwritten, certain terms of the Subordinated Securities
have been established pursuant to a Board Resolution, an Officer's Certificate
or a Supplemental Subordinated Indenture in accordance with this Subordinated
Indenture, and when such other terms as are to be established pursuant to
procedures set forth in a Company Order shall have been established, all such
terms will have been duly authorized by the Company and will have been
established in conformity with the provisions of this Subordinated Indenture;

              (c) such Subordinated Securities, when executed and issued by the
Company and authenticated by the Trustee in accordance with the provisions of
this Subordinated Indenture and duly paid for by the purchasers thereof, and
subject to any conditions specified in such Opinion of Counsel, will constitute
valid and binding obligations of the Company, except as any rights thereunder
may be limited by the effect of bankruptcy, insolvency, reorganization,
receivership, conservatorship, arrangement, moratorium or other laws affecting
or relating to the rights of creditors generally; the rules governing the
availability of specific performance, injunctive relief or other equitable
remedies and general principles of equity, regardless of whether considered in a
proceeding in equity or at law; the effect of applicable court decisions
invoking statutes or principles of equity, which have held that certain

                                      12
<PAGE>

covenants and provisions of agreements are unenforceable where the breach of
such covenants or provisions imposes restrictions or burdens upon a borrower,
and it cannot be demonstrated that the enforcement of such restrictions or
burdens is necessary for the protection of the creditor, or which have held that
the creditor's enforcement of such covenants or provisions under the
circumstances would have violated the creditor's covenants of good faith and
fair dealing implied under California law; and the effect of California statutes
and rules of law which cannot be waived prospectively by a borrower,  and such
counsel need express no opinion with regard to the enforceability of Section
7.06 or of a judgment denominated in a currency other than United States
Dollars; and

          (d) the Company has complied with all applicable Federal laws and
requirements in respect of the execution and delivery of such Subordinated
Securities.

          In rendering such opinions, any counsel may qualify any opinions as to
enforceability by stating that such enforceability may be limited by bankruptcy,
insolvency, reorganization, liquidation, moratorium, fraudulent transfer and
other similar laws affecting the rights and remedies of creditors and is subject
to general principles of equity (regardless of whether such enforceability is
considered in a proceeding in equity or at law).  Such counsel may rely upon
opinions of other counsel (copies of which shall be delivered to the Trustee)
reasonably satisfactory to the Trustee, in which case the opinion shall state
that such counsel believes he and the Trustee are entitled so to rely.  Such
counsel may also state that, insofar as such opinion involves factual matters,
he has relied, to the extent he deems proper, upon certificates of officers of
the Company and its subsidiaries and certificates of public officials.

          The Trustee shall have the right to decline to authenticate and
deliver any Subordinated Securities under this section if the Trustee, being
advised by counsel, determines that such action may not lawfully be taken by the
Company or if the Trustee in good faith by its board of directors or board of
trustees, executive committee or a trust committee of directors or trustees
shall determine that such action would expose the Trustee to personal liability
to existing Holders or would affect the Trustee's own rights, duties or
immunities under the Subordinated Securities, this Subordinated Indenture or
otherwise.

     SECTION 2.05.  Execution of Subordinated Securities.  The Subordinated
                    ------------------------------------
Securities and each Coupon appertaining thereto, if any, shall be executed
manually or in facsimile, by any two of the Chairman of the Board, Chief
Executive Officer, the President, and Vice President, the Secretary, any
Assistant Secretary, the Chief Financial Officer, the Treasurer or any Assistant
Treasurer of the Company under its corporate seal (except in the case of
Coupons), which may be affixed thereto or printed, engraved or otherwise
reproduced thereon, by facsimile or otherwise.  Only such Subordinated
Securities or Coupons, if any, as shall bear thereon a certificate of
authentication substantially in the form recited herein, executed by the Trustee
manually by an authorized officer, shall be entitled to the benefits of this
Subordinated Indenture or be valid or obligatory for any purpose.  Such
certificate of authentication of the Trustee upon any Subordinated Security or
Coupon, if any, executed by the Company shall be conclusive evidence that the
Subordinated Security or Coupon so authenticated has been duly authenticated and
delivered hereunder and that the Holder is entitled to the benefits of this
Subordinated Indenture.  Typographical or other errors or defects in the seal or
facsimile signature on any

                                       13
<PAGE>

Subordinated Security or in the text thereof shall not affect the validity or
enforceability of such Subordinated Security if it has been duly authenticated
and delivered by the Trustee.

     In case any officer of the Company who shall have signed any of the
Subordinated Securities or Coupons, if any, (manually or in facsimile) shall
cease to be such officer before the Subordinated Securities or Coupons so signed
shall have been authenticated and delivered by the Trustee, or disposed of by
the Company, such Subordinated Securities or Coupons nevertheless may be
authenticated and delivered or disposed of as though the Person who signed such
Subordinated Securities or Coupons had not ceased to be such officer of the
Company.  Also, any Subordinated Security or Coupon may be signed on behalf of
the Company by such Persons as on the actual date of execution of such
Subordinated Security or Coupon shall be the proper officers of the Company,
although at the date of the execution of this Subordinated Indenture or on the
nominal date of such Subordinated Security any such Person was not such officer.

     SECTION 2.06.  Certificate of Authentication.  Only such Subordinated
                    -----------------------------
Securities as shall bear thereon a certificate of authentication substantially
in the form hereinbefore recited, executed by the Trustee by the manual
signature of one of its authorized officers, shall be entitled to the benefits
of this Subordinated Indenture or be valid or obligatory for any purpose.  No
Coupon shall be entitled to the benefits of this Subordinated Indenture or shall
be valid and obligatory for any purpose until the certificate of authentication
on the Subordinated Security to which such Coupon appertains shall have been
duly executed by the Trustee.  The execution of such certificate by the Trustee
upon any Subordinated Security executed by the Company shall be conclusive
evidence that the Subordinated Security so authenticated has been duly
authenticated and delivered hereunder and that the Holder is entitled to the
benefits of this Subordinated Indenture.

     SECTION 2.07.  Denominations; Payment of Interest on Subordinated
                    --------------------------------------------------
Securities.
----------

     (a) The Subordinated Securities of each series may be issued as Registered
Subordinated Securities or Unregistered Subordinated Securities in denominations
all as shall be specified as contemplated by Section 2.03.  In the absence of
such provisions with respect to the Registered Subordinated Securities of any
series, the Subordinated Securities of such series (other than any Registered
Global Subordinated Securities) shall be issued in denominations of $1,000 (or
[Euro] 1,000, as applicable) and any integral multiple thereof.  If
denominations of Unregistered Subordinated Securities of any series are not so
established, such Subordinated Securities shall be issuable in denominations of
$1,000 and $5,000 (or [Euro] 1,000 and [Euro] 5,000).  The Subordinated
Securities of each series shall be numbered, lettered or otherwise distinguished
in such manner or in accordance with such plan as the officers of the Company
executing the same may determine with the approval of the Trustee, as evidenced
by the execution and authentication thereof.

     (b) If the Subordinated Securities of any series shall bear interest, each
Subordinated Security of such series shall bear interest from the applicable
date at the rate per annum specified in the Officer's Certificate or
Supplemental Subordinated Indenture with respect to such series of Subordinated
Securities.  Unless otherwise specified in the Officer's Certificate or
Supplemental Subordinated Indenture with respect to the Subordinated Securities
of any series, interest on the Subordinated Securities of such series shall be
computed on the basis of a 360-day year of twelve

                                       14
<PAGE>

30-day months. Such interest shall be payable on the Interest Payment Dates
specified in the Officer's Certificate or Supplemental Subordinated Indenture
with respect to such series of Subordinated Securities. The Person in whose name
any Subordinated Security (or one or more Predecessor Subordinated Securities)
is registered at the close of business on the applicable Record Date for the
series of which such Subordinated Security is a part shall be entitled to
receive the interest payable thereon on such Interest Payment Date
notwithstanding the cancellation of such Subordinated Security upon any transfer
or exchange thereof subsequent to such Record Date and prior to such Interest
Payment Date unless such Subordinated Security shall have been called for
redemption on a Redemption Date which is subsequent to such Record Date and
prior to such Interest Payment Date or unless the Company shall default in the
payment of interest due on such Interest Payment Date on any Subordinated
Security of such series.

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

     (1) The Company may elect to make payment of any Defaulted Interest on the
Subordinated Securities of any series to the Persons in whose names such
Subordinated Securities (or their respective Predecessor Subordinated
Securities) are registered at the close of business on a Special Record Date for
the payment of such Defaulted Interest, which shall be fixed in the following
manner.  The Company shall notify the Trustee in writing of the amount of
Defaulted Interest proposed to be paid on each Subordinated Security and the
date of the proposed payment (which date shall be such as will enable the
Trustee to comply with the next sentence hereof), and at the same time the
Company shall deposit with the Trustee an amount of money equal to the aggregate
amount proposed to be paid in respect of such Defaulted Interest or shall make
arrangements satisfactory to the Trustee for such deposit prior to the date of
the proposed payment, such money when deposited to be held in trust for the
benefit of the Persons entitled to such Defaulted Interest as in this subsection
provided.  Thereupon the Trustee shall fix a Special Record Date for the payment
of such Defaulted Interest which shall be not more than 15 nor less than 10 days
prior to the date of the proposed payment and not less than 10 days after the
receipt by the Trustee of the notice of the proposed payment.  The Trustee shall
promptly notify the Company of such Special Record Date and, in the name and at
the expense of the Company, shall cause notice of the proposed payment of such
Defaulted Interest and the Special Record Date therefor to be mailed, first-
class postage prepaid, to each Holder of a Subordinated Security of such series
at such Holder's address as it appears in the Register not less than 10 days
prior to such Special Record Date.  Notice of the proposed payment of such
Defaulted Interest and the Special Record Date therefor having been mailed as
aforesaid, such Defaulted Interest shall be paid to the Persons in whose names
the Subordinated Securities of such series are registered on such Special Record
Date and shall no longer be payable pursuant to the following subsection (2).

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

                                       15
<PAGE>

proposed payment pursuant to this subsection, such payment shall be deemed
practicable by the Trustee.

     Interest on Subordinated Securities of any series that bear interest may be
paid by mailing a check to the address of the person entitled thereto as such
address shall appear in the Register.

     Subject to the foregoing provisions of this Section 2.07, each Subordinated
Security delivered under this Subordinated Indenture upon transfer of or in
exchange for or in lieu of any other Subordinated Security shall carry all the
rights to interest accrued and unpaid, and to accrue, which were carried by such
other Subordinated Security and each such Subordinated Security shall bear
interest from such date, such that neither gain nor loss in interest shall
result from such transfer, exchange or substitution.

     SECTION 2.08.  Registration, Transfer and Exchange of Subordinated
                    ---------------------------------------------------
Securities.  Except as specifically otherwise provided herein with respect to
----------
Registered Global Subordinated Securities, Subordinated Securities of any series
may be exchanged for a like aggregate principal amount of Subordinated
Securities of the same series of other authorized denominations.  Subordinated
Securities to be exchanged shall be surrendered at the offices or agencies to be
maintained in accordance with the provisions of Section 4.03 and the Company
shall execute the Subordinated Security or Subordinated Securities, and the
Trustee shall authenticate and deliver in exchange therefor the Subordinated
Security or Subordinated Securities which the Subordinated Securityholder making
the exchange shall be entitled to receive.

     The Company shall cause the Trustee to keep or cause to be kept, at  one or
more of the offices or agencies to be maintained by the Trustee in accordance
with the provisions of Section 4.04 with respect to the Subordinated Securities
of each series, the Register in which, subject to such reasonable regulations as
it may prescribe, the Company shall provide for the registration of the
Registered Subordinated Securities of such series and the transfer of Registered
Subordinated Securities of such series as in this Article provided.  The
Register shall be in written form or in any other form capable of being
converted into written form within a reasonable time.  At all reasonable times
the Register shall be open for inspection by the Trustee and any registrar of
the Subordinated Securities of such series other than the Trustee.  Upon due
presentment for transfer of any Subordinated Security of any series at the
offices or agencies of the Company to be maintained in accordance with Section
4.03 with respect to the Registered Subordinated Securities of such series, the
Company shall execute a new Subordinated Security and the Trustee shall
authenticate and deliver in the name of the transferee or transferees a new
Subordinated Security or Registered Subordinated Securities of the same series
for a like aggregate principal amount of authorized denominations.
Notwithstanding any other provisions of this Section 2.08, unless and until it
is exchanged in whole or in part for Registered Subordinated Securities in
definitive form, a Global Subordinated Security representing all or a portion of
the Registered Subordinated Securities of a series may not be transferred except
as a whole by the Depository for such series to a nominee of such Depository or
by a nominee of such Depository to such Depository or another nominee of such
Depository or by such Depository or any such nominee to a successor Depository
for such series or a nominee of such successor Depository.

     Unregistered Subordinated Securities (except for any temporary global
Unregistered Subordinated Securities) and Coupons (except for Coupons attached
to any temporary global Unregistered Subordinated Securities) shall be
transferable by delivery.

     At the option of the Holder thereof, Registered Subordinated Securities of
any series (other than a Registered Global Subordinated Security, except as set
forth below) may be exchanged for a Registered Subordinated Security or
Registered Subordinated Securities of such series and tenor having authorized
denominations and an equal aggregate principal amount, upon surrender of such
Registered Subordinated Securities to be exchanged at the agency of the Company
that shall be maintained for such purpose in accordance with Section 4.03 and
upon payment, if the Company shall so require, of the charges hereinafter
provided.  If the Subordinated Securities of any series are issued in both
registered and unregistered form, except as otherwise established pursuant to
Section 2.03, at the option of the Holder thereof, Unregistered Subordinated
Securities of any series may be exchanged for Registered Subordinated Securities
of such series and tenor having authorized denominations and an equal aggregate
principal amount, upon surrender of such Unregistered Subordinated Securities to
be exchanged at the agency of the Company that shall be maintained for such
purpose in accordance with Section 4.03, with, in the case of Unregistered
Subordinated Securities that have Coupons attached, all unmatured Coupons and
all matured Coupons in default thereto appertaining, and upon payment, if the
Company shall so require, of the charges hereinafter provided.  At the option of
the Holder thereof, if Unregistered Subordinated Securities of any series,
maturity date, interest rate and original issue date are issued in more than one
authorized denomination, except as otherwise established pursuant to Section
2.03, such Unregistered Subordinated Securities may be exchanged for
Unregistered Subordinated Securities of such series and tenor having authorized
denominations and an equal aggregate principal amount, upon surrender of such
Unregistered Subordinated Securities to be exchanged at the agency of the
Company that shall be maintained for such purpose in accordance with Section
4.03, with, in the case of Unregistered Subordinated Securities that have
Coupons attached, all unmatured Coupons and all matured Coupons in default
thereto appertaining, and upon payment, if the Company shall so require, of the
charges hereinafter provided.  Registered Subordinated Securities of any series
may not be exchanged for Unregistered Subordinated Securities of such series
unless (1) otherwise specified pursuant to Section 2.03 and (2) the Company has
delivered to the Trustee an Opinion of Counsel that (x) the Company has received
from the IRS a ruling or (y) since the date hereof, there has been a change in
the applicable United States federal income tax law, in either case to the
effect that the inclusion of terms permitting Registered Subordinated Securities
to be exchanged for Unregistered Subordinated Securities would result in no
United States federal income tax effect adverse to the Company or to any Holder.
Whenever any Subordinated Securities are so surrendered for exchange, the
Company shall execute, and the Trustee shall authenticate and deliver, the
Subordinated Securities which the Holder making the exchange is entitled to
receive.  All Subordinated Securities and Coupons, if any, surrendered upon any
exchange or transfer provided for in this Subordinated Indenture shall be
promptly cancelled and disposed of by the Trustee, and the Trustee shall deliver
a certificate of disposition thereof to the Company.

     All Registered Subordinated Securities of any series presented or
surrendered for exchange, transfer, redemption, conversion or payment shall, if
so required by the Company or any registrar of the Subordinated Securities of
such series, be accompanied by a written

                                       17
<PAGE>

instrument or instruments of transfer, in form satisfactory to the Company and
such registrar, duly executed by the registered Holder or by such Person's
attorney duly authorized in writing.

     No service charge shall be made for any exchange or registration of
transfer of Subordinated Securities, but 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 Company shall not be required to exchange or transfer (a) any
Subordinated Securities of any series during a period beginning at the opening
of business 15 days before the day of the first publication or the mailing (if
there is no publication) of a notice of redemption of Subordinated Securities of
such series and ending at the close of business on the day of such publication
or mailing or (b) any Subordinated Securities called or selected for redemption
in whole or in part, except, in the case of Subordinated Securities called for
redemption in part, the portion thereof not so called for redemption in whole or
in part or during a period beginning at the opening of business on any Record
Date for such series and ending at the close of business on the relevant
Interest Payment Date therefor.

     SECTION 2.09.  Mutilated, Defaced, Destroyed, Lost and Stolen Subordinated
                    -----------------------------------------------------------
Securities.  In case any temporary or definitive Subordinated Security or any
----------
Coupon appertaining to any Subordinated Security shall be mutilated, defaced,
destroyed, lost or stolen, the Company in its discretion may execute and, upon
the written request of any officer of the Company, the Trustee shall
authenticate and delivery, a new Subordinated Security of the same series,
maturity date, interest rate and original issue date, bearing a number or other
distinguishing symbol not contemporaneously outstanding, in exchange and
substitution for the mutilated or defaced Subordinated Security, or in lieu of
and in substitution for the Subordinated Security so destroyed, lost or stolen
with Coupons corresponding to the Coupons appertaining to the Subordinated
Securities so mutilated, defaced, destroyed, lost or stolen, or in exchange or
substitution for the Subordinated Security to which such mutilated, defaced,
destroyed, lost or stolen Coupon appertained, with Coupons appertaining thereto
corresponding to the Coupons so mutilated, defaced, destroyed, lost or stolen.
In every case the applicant for a substitute Subordinated Security or Coupon
shall furnish to the Company and to the Trustee and any agent of the Company or
the Trustee such security or indemnity as may be required by them to indemnify
and defend and to save each of them harmless and, in every case of destruction,
loss or theft, evidence to their satisfaction of the destruction, loss or theft
of such Subordinated Security or Coupon and of the ownership thereof, and in the
case of mutilation or defacement shall surrender the Subordinated Security and
related Coupons to the Trustee or such agent.

     Upon the issuance of any substitute Subordinated Security or Coupon, the
Company may require the payment of a sum sufficient to cover any tax or other
governmental charge that may be imposed in relation thereto and any other
expenses (including the fees and expenses of the Trustee) or its agent connected
therewith.  In case any Subordinated Security or Coupon which has matured or is
about to mature or has been called for redemption in full shall become mutilated
or defaced or be destroyed, lost or stolen, the Company may instead of issuing a
substitute Subordinated Security, pay or authorize the payment of the same or
the relevant Coupon (without surrender thereof except in the case of a mutilated
or defaced Subordinated Security or Coupon), if the applicant for such payment
shall furnish to the Company and to the Trustee and any agent of the Company or
the Trustee such security or indemnity as any of them

                                       18
<PAGE>

may require to save each of them harmless, and, in every case of destruction,
loss or theft, the applicant shall also furnish to the Company and to the
Trustee and any agent of the Company or the Trustee evidence to their
satisfaction of the destruction, loss or theft of such Subordinated Security or
Coupons and of the ownership thereof.

     Every substitute Subordinated Security or Coupon of any series issued
pursuant to the provisions of this Section by virtue of the fact that any such
Subordinated Security or Coupon is destroyed, lost or stolen shall constitute an
additional contractual obligation of the Company, whether or not the destroyed,
lost or stolen Subordinated Security or Coupon shall be at any time enforceable
by anyone and shall be entitled to all the benefits of (but shall be subject to
all the limitations of rights set forth in) this Subordinated Indenture equally
and proportionately with any and all other Subordinated Securities or Coupons of
such series duly authenticated and delivered hereunder.  All Subordinated
Securities and Coupons shall be held and owned upon the express condition that,
to the extent permitted by law, the foregoing provisions are exclusive with
respect to the replacement or payment of mutilated, defaced or destroyed, lost
or stolen Subordinated Securities and Coupons and shall preclude any and all
other rights or remedies notwithstanding any law or statue existing or hereafter
enacted to the contrary with respect to the replacement or payment of negotiable
instruments or other securities without their surrender.

     SECTION 2.10.  Cancellation and Destruction of Surrendered Subordinated
                    --------------------------------------------------------
Securities.  All Subordinated Securities and Coupons surrendered for payment,
----------
redemption, transfer, conversion or exchange, or for credit against any payment
in respect of a sinking or analogous fund, if any, shall, if surrendered to the
Company, the Trustee or any agent of the Company or of the Trustee, be delivered
to the Trustee, and the same, together with Subordinated Securities surrendered
to the Trustee for cancellation, shall be canceled by it and thereafter disposed
of by it as directed by the Company, and no Subordinated Securities or Coupons
shall be issued in lieu thereof except as expressly permitted by any of the
provisions of this Subordinated Indenture. The Trustee shall destroy canceled
Subordinated Securities and Coupons and deliver a certificate of destruction
thereof to the Company unless by an Officer's Certificate of the Company, the
Company shall direct that canceled Subordinated Securities be returned to it. If
the Company shall purchase or otherwise acquire any of the Subordinated
Securities and Coupons, however, such purchase or acquisition shall not operate
as a payment, redemption or satisfaction of the indebtedness represented by such
Subordinated Securities or Coupons unless and until the Company, at its option
shall deliver or surrender the same to the Trustee for cancellation.

     SECTION 2.11.  Temporary Subordinated Securities.  Pending the preparation
                    ---------------------------------
of definitive Subordinated Securities of any series, the Company may execute and
the Trustee shall authenticate and deliver temporary Subordinated Securities of
such series which are printed, lithographed, typewritten or otherwise produced,
in each case satisfactory to the Trustee.  Temporary Subordinated Securities of
any series shall be issuable as Registered Subordinated Securities without
coupons, or as Unregistered Subordinated Securities with or without coupons
attached thereto of any authorized denomination, and substantially in the form
of the definitive Subordinated Securities of such series but with such
appropriate omissions, insertions, substitutions and other variations as the
officers executing such Subordinated Securities may determine, as evidenced by
their execution of such Subordinated

                                       19
<PAGE>

Securities. Every such temporary Subordinated Security shall be authenticated by
the Trustee upon the same conditions and in substantially the same manner, and
with the same effect, as the definitive Subordinated Securities. If temporary
Subordinated Securities are issued, the Company will cause definitive
Subordinated Securities to be prepared without unreasonable delay. After the
preparation of definitive Subordinated Securities, the temporary Subordinated
Securities of such series shall be exchangeable for definitive Subordinated
Securities upon surrender of the temporary Subordinated Securities without
charge to the Holder at the offices or agencies to be maintained by the Trustee
as provided in Section 4.03 with respect to the Subordinated Securities of such
series and in the case of Unregistered Subordinated Securities, at any agency
maintained by the Company for such purpose as specified pursuant to Section
2.03. Upon surrender for cancellation of any one or more temporary Subordinated
Securities the Company shall execute and the Trustee shall authenticate and
deliver in exchange for such temporary Subordinated Securities an equal
aggregate principal amount of definitive Subordinated Securities of such series
and in the case of Unregistered Subordinated Securities, having attached thereto
any appropriate Coupons. Until so exchanged, the temporary Subordinated
Securities of any series shall in all respects be entitled to the benefits of
this Subordinated Indenture and interest thereon, when and as payable, shall be
paid to the registered owners thereof. The provisions of this Section are
subject to any restrictions or limitations on the issue and delivery of
temporary Unregistered Subordinated Securities of any series that may be
established pursuant to Section 2.03 (including any provision that Unregistered
Subordinated Securities of such series initially be issued in the form of a
single global Unregistered Subordinated Security to be delivered to a depositary
or agency located outside the United States and the procedures pursuant to which
definitive or global Unregistered Subordinated Securities of such series would
be issued in exchange for such temporary global Unregistered Subordinated
Security).

     SECTION 2.12.  Subordinated Securities in Global Form; Depositories.  (a)
                    ----------------------------------------------------
Each Registered Global Subordinated Security shall:  (i) represent and be
denominated in an aggregate amount equal to the aggregate principal amount of
the Subordinated Securities of the series to be represented by such Registered
Global Subordinated Security, (ii) be registered in the name of either the
Depository for such Registered Global Subordinated Security or the nominee of
such Depository, (iii) be delivered by the Trustee to such Depository or
pursuant to such Depository's written instruction and (iv) bear a legend
substantially to the following effect:  "Unless and until it is exchanged in
whole or in part for Subordinated Securities in definitive form, this Registered
Global Subordinated Security may not be transferred except as a whole by the
Depository to a nominee of the Depository or by a nominee of the Depository to
the Depository or another nominee of the Depository or by the Depository or any
nominee to a successor Depository or a nominee of any successor Depository."
The notation of the record owner's interest in such Registered Global
Subordinated Security upon the original issuance thereof shall be deemed to be
delivery in connection with the original issuance of each beneficial owner's
interest in such Registered Global Subordinated Security. Without limiting the
foregoing, the Company and the Trustee shall have no responsibility, obligation
or liability with respect to: (x) the maintenance, review or accuracy of the
records of the Depository or of any of its participating organizations with
respect to any ownership interest in or payments with respect to such Registered
Global Subordinated Security, (y) any communication with or delivery of any
notice (including notices of redemption) with respect to the series of
Subordinated Securities represented by the Registered Global Subordinated
Security to any Person having any ownership interest in such Registered Global
Subordinated Security or to any of the Depository's participating organizations
or (z) any payment made on account of any beneficial ownership interest in such
Registered Global Subordinated Security.

                                       20
<PAGE>

     (b) If any Subordinated Security of a series is issuable in the form of a
Registered Global Subordinated Security or Subordinated Securities, each such
Registered Global Subordinated Security may provide that it shall represent the
aggregate amount of Outstanding Subordinated Securities of such series from time
to time endorsed thereon and may also provide that the aggregate amount of
Outstanding Subordinated Securities of such series represented thereby may from
time to time be reduced to reflect exchanges.  Any endorsement of a Registered
Global Subordinated Security to reflect the amount of Outstanding Subordinated
Securities of a series represented thereby shall be made by the Trustee and in
such manner as shall be specified on such Registered Global Subordinated
Security.  Any instructions by the Company with respect to a Registered Global
Subordinated Security, after its initial issuance, shall be in writing but need
not comply with Section 13.03 of this Subordinated Indenture.

     (c) Each Depository designated pursuant to the provisions of Section 2.03
of this Subordinated Indenture for a Registered Global Subordinated Security
must, at the time of its designation and at all times while it serves as a
depositary, be a clearing agency registered under the Exchange Act, and any
other applicable statute or regulation.  If at any time the Depository for the
Subordinated Securities of a series notifies the Company that it is unwilling or
unable to continue as Depository for the Subordinated Securities of such series
or if at any time the Depository for the Subordinated Securities of such series
shall no longer be eligible under this Section 2.12, the Company shall appoint a
successor Depository with respect to the Subordinated Securities of such series.
If a successor Depository for the Subordinated Securities of such series is not
appointed by the Company within 90 days after the Company receives such notice
or learns of such ineligibility, the Company shall execute and the Company shall
direct the Trustee to authenticate and deliver definitive Subordinated
Securities of such series in authorized denominations in exchange for the
Registered Global Subordinated Security or Subordinated Securities.  Upon
receipt of such direction, the Trustee shall thereupon authenticate and deliver
the definitive Subordinated Securities of such series in the same aggregate
principal amount as the Registered Global Subordinated Security or Subordinated
Securities representing such series in exchange for such Registered Global
Subordinated Security or Subordinated Securities, in accordance with the
provisions of subsection (e) of this Section 2.12, without any further corporate
action by the Company.

     (d) The Company may at any time and in its sole discretion determine that
the Registered Subordinated Securities of any series issued in the form of one
or more Registered Global Subordinated Securities shall no longer be represented
by such Registered Global Subordinated Security or Subordinated Securities.  In
such event, the Company will execute and upon receipt of a written order from
the Company, the Trustee shall thereupon authenticate and deliver Subordinated
Securities of such series in definitive form and in authorized denominations in
an aggregate principal amount equal to the principal amount of the Registered
Global Subordinated Security or Subordinated Securities representing such series
in exchange for such Registered Global Subordinated Security or Subordinated
Securities, in accordance with the provisions of subsection (e) of this Section
2.12 without any further corporate action by the Company.

     (e) Upon any exchange hereunder of the Registered Global Subordinated
Security or Subordinated Securities for Subordinated Securities in definitive
form, such Registered Global Subordinated Security or Subordinated Securities
shall be canceled by the Trustee.  Registered

                                       21
<PAGE>

Subordinated Securities issued hereunder in exchange for the Registered Global
Subordinated Security or Subordinated Securities shall be registered in such
names and in such authorized denominations as the Depository for such Registered
Global Subordinated Security, pursuant to instructions from its direct or
indirect participants or otherwise, shall instruct the Trustee. The Trustee
shall deliver such definitive Subordinated Securities in exchange for the
Registered Global Subordinated Security or Subordinated Securities to the
persons in whose name such definitive Subordinated Securities have been
registered in accordance with the directions of the Depository.

     (f) Any time the Registered Subordinated Securities of any series are not
in the form of Registered Global Subordinated Securities pursuant to the
preceding two paragraphs, the Company agrees to supply the Trustee with a
reasonable supply of certified Registered Subordinated Securities without the
legend required by this Section 2.12 and the Trustee agrees to hold such
Registered Subordinated Securities in safekeeping until authenticated and
delivered pursuant to the terms of this Subordinated Indenture.

     If established by the Company pursuant to Section 2.03 with respect to any
Registered Global Subordinated Security, the Depositary for such Registered
Global Subordinated Security may surrender such Registered Global Subordinated
Security in exchange in whole or in part for Subordinated Securities of the same
series and tenor in definitive registered form on such terms as are acceptable
to the Company and such Depositary.  Thereupon, the Company shall execute, and
the Trustee shall authenticate and deliver, without service charge,

          (i)  to the Person specified by such Depositary new Registered
     Subordinated Securities of the same series and tenor, of any authorized
     denominations as requested by such Person, in an aggregate principal amount
     equal to and in exchange for such Person's beneficial interest in the
     Registered Global Subordinated Security; and

          (ii) to such Depositary a new Registered Global Subordinated Security
     in a denomination equal to the difference, if any, between the principal
     amount of the surrendered Registered Global Subordinated Security and the
     aggregate principal amount of Registered Subordinated Securities
     authenticated and delivered pursuant to clause (i) above.

     Registered Subordinated Securities issued in exchange for a Registered
Global Subordinated Security pursuant to this Section 2.12 shall be registered
in such names and in such authorized denominations as the Depositary for such
Registered Global Subordinated Security, pursuant to instructions from its
direct or indirect participants or otherwise, shall instruct the Trustee or an
agent of the Company or the Trustee.  The Trustee or such agent shall deliver
such Subordinated Securities to or as directed by the Persons in whose names
such Subordinated Securities are so registered.

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

                                       22
<PAGE>

     Notwithstanding anything herein or in the forms or terms of any
Subordinated Securities to the contrary, none of the Company, the Trustee or any
agent of the Company or the Trustee shall be required to exchange any
Unregistered Subordinated Security for a Registered Subordinated Security if
such exchange would result in adverse Federal income tax consequences to the
Company (such as, for example, the inability of the Company to deduct from its
income, as computed for Federal income tax purposes, the interest payable on the
Unregistered Subordinated Securities) under then applicable United States
Federal income tax laws.  The Trustee and any such agent shall be entitled to
rely on an Officers' Certificate or an Opinion of Counsel in determining such
result.

     SECTION 2.13.  CUSIP Numbers.  The Company in issuing the Subordinated
                    -------------
Securities may use "CUSIP" and "CINS" numbers (if then generally in use), and
the Trustee shall use CUSIP numbers or CINS numbers, as the case may be, in
notices of redemption or exchange as a convenience to Holders and no
representation shall be made as to the correctness of such numbers either as
printed on the Subordinated Securities or as contained in any notice of
redemption or exchange.

     SECTION 2.14.  Series May Include Tranches.  A series of Subordinated
                    ---------------------------
Securities may include one or more tranches (each a "tranche") of Subordinated
Securities, including Subordinated Securities issued in a Periodic Offering.
The Subordinated Securities of different tranches may have one or more different
terms, including authentication dates and public offering prices, but all the
Subordinated Securities within each such tranche shall have identical terms,
including authentication date and public offering price.  Notwithstanding any
other provisions of this Subordinated Indenture, with respect to Sections 2.05
through 2.12, 3.01 through 3.06, 4.03, 6.01 through 6.12, 10.02 and 11.01
through 11.05, if any series of Subordinated Securities includes more than one
tranche, all provisions of such sections applicable to any series of
Subordinated Securities shall be deemed equally applicable to each tranche of
any series of Subordinated Securities in the same manner as though originally
designated a series unless otherwise provided with respect to such series or
tranche pursuant to Section 2.03.  In particular, and without limiting the scope
of the next preceding sentence, any of the provisions of such sections which
provide for or permit action to be taken with respect to a series of
Subordinated Securities shall also be deemed to provide for and permit such
action to be taken instead only with respect to Subordinated Securities of one
or more tranches within that series (and such provisions shall be deemed
satisfied thereby), even if no comparable action is taken with respect to
Subordinated Securities in the remaining tranches of that series.

                                 ARTICLE THREE

            REDEMPTION OF SUBORDINATED SECURITIES AND SINKING FUNDS

     SECTION 3.01.  Applicability of Article.  The provisions of this Article
                    ------------------------
shall be applicable to the Subordinated Securities of any series which are
redeemable before their Stated Maturity or to any sinking fund for the
retirement of Subordinated Securities of a series except as otherwise specified
as contemplated by Section 2.03 for Subordinated Securities of such series.

     SECTION 3.02.  Notice of Redemption; Partial Redemptions.  Notice of
                    -----------------------------------------
redemption to the Holders of Registered Subordinated Securities of any series to
be redeemed as a whole or in

                                       23
<PAGE>

part at the option of the Company shall be given by mailing notice of such
redemption by first class mail, postage prepaid, at least 30 days and not more
than 60 days prior to the date fixed for redemption to such Holders of
Subordinated Securities of such series at their last addresses as they shall
appear upon the Register. Notice of redemption to the Holders of Unregistered
Subordinated Securities to be redeemed as a whole or in part, who have filed
their names and addresses with the Trustee pursuant to Section 313(c)(2) of the
Trust Indenture Act shall be given by mailing notice of such redemption, by
first class mail, postage prepaid, at least 30 days and not more than 60 prior
to the date fixed for redemption, to such Holders at such addresses as were so
furnished to the Trustee (and, in the case of any such notice given by the
Company, the Trustee shall make such information available to the Company for
such purpose). Notice of redemption to all other Holders of Unregistered
Subordinated Securities shall be published in an Authorized Newspaper in the
Borough of Manhattan, The City of New York and in an Authorized Newspaper in
London (and, if required by Section 4.09, in an Authorized Newspaper in
Luxembourg), in each case, once in each of three successive calendar weeks, the
first publication to be not less than 30 nor more than 60 days prior to the date
fixed for redemption. Any notice which is mailed in the manner herein provided
shall be conclusively presumed to have been duly given, whether or not the
Holder receives the notice. Failure to give notice by mail, or any defect in the
notice to the Holder of any Subordinated Security of a series designated for
redemption as a whole or in part shall not affect the validity of the
proceedings for the redemption of such Subordinated Security of such series.

     The notice of redemption to each such Holder shall specify the principal
amount of each Subordinated Security of such series held by such Holder to be
redeemed, the date fixed for redemption, the redemption price, the place or
places of payment, that payment will be made upon presentation and surrender of
such Subordinated Securities and, in the case of Subordinated Securities with
Coupons attached thereto, of all Coupons appertaining thereto maturing after the
date fixed for redemption, that such redemption is pursuant to the mandatory or
optional sinking fund, or both, if such be the case, that interest accrued to
the date fixed for redemption will be paid as specified in such notice and that
on and after said date interest thereon or on the portions thereof to be
redeemed will cease to accrue.  In case any Subordinated Security of a series is
to be redeemed in part only the notice of redemption shall state the portion of
the principal amount thereof to be redeemed and shall state that on and after
the date fixed for redemption, upon surrender of such Subordinated Security, a
new Subordinated Security or Subordinated Securities of such series in principal
amount equal to the unredeemed portion thereof will be issued.

     The notice of redemption of Subordinated Securities of any series to be
redeemed at the option of the Company shall be given by the Company or, at the
Company's request, by the Trustee in the name and at the expense of the Company.

     On or before the redemption date specified in the notice of redemption
given as provided in this Section, the Company will deposit with the Trustee or
with one or more Paying Agents (or, if the Company is acting as its own Paying
Agent,  set aside, segregate and holder in trust as provided in Section 4.05) an
amount of money sufficient to redeem on the redemption date all the Subordinated
Securities of such series so called for redemption at the appropriate redemption
price, together with accrued interest to the date fixed for redemption.  The
Company will deliver to the Trustee at least 70 days prior to the date fixed for
redemption, or such shorter period as shall be acceptable to the Trustee, an
Officer's Certificate stating the aggregate principal amount

                                       24
<PAGE>

of Subordinated Securities to be redeemed. In case of a redemption at the
election of the Company prior to the expiration of any restriction on such
redemption, the Company shall deliver to the Trustee, prior to the giving of any
notice of redemption to Holders pursuant to this Section, an Officer's
Certificate stating that such restriction has been complied with.

     If less than all the Subordinated Securities of a series are to be
redeemed, the Trustee shall select, in such manner as it shall deem appropriate
and fair, in its sole discretion, Subordinated Securities of such series to be
redeemed in whole or in part.  Subordinated Securities may be redeemed in part
in multiples equal to the minimum authorized denomination for Subordinated
Securities of such series or any multiple thereof.  The Trustee shall promptly
notify the Company in writing of the Subordinated Securities of such series
selected for redemption and, in the case of any Subordinated Securities of such
series selected for partial redemption, the principal amount thereof to be
redeemed.  For all purposes of this Subordinated Indenture, unless the context
otherwise requires, all provisions relating to the redemption of Subordinated
Securities of any series shall relate, in the case of any Subordinated Security
redeemed or to be redeemed only in part, to the portion of the principal amount
of such Subordinated Security which has been or is to be redeemed.

     SECTION 3.03.  Payment of Subordinated Securities Called for Redemption.
                    --------------------------------------------------------
If notice of redemption has been given as above provided, the Subordinated
Securities or portions of Subordinated Securities specified in such notice shall
become due and payable on the date and at the place stated in such notice at the
applicable redemption price, together with interest accrued to the date fixed
for redemption, and on and after said date (unless the Company shall default in
the payment of such Subordinated Securities at the redemption price, together
with interest accrued to said date) interest on the Subordinated Securities or
portions of Subordinated Securities so called for redemption shall cease to
accrue, and the unmatured Coupons, if any, appertaining thereto shall be void,
and, except as provided in Sections 7.05 and 11.04, such Subordinated Securities
shall cease from and after the date fixed for redemption to be entitled to any
benefit or security under this Subordinated Indenture, and the Holders thereof
shall have no right in respect of such Subordinated Securities except the right
to receive the redemption price thereof and unpaid interest to the date fixed
for redemption.  On presentation and surrender of such Subordinated Securities
at a place of payment specified in said notice, together with all Coupons, if
any, appertaining thereto maturing after the date fixed for redemption, said
Subordinated Securities or the specified portions thereof shall be paid and
redeemed by the Company at the applicable redemption price, together with
interest accrued thereon to the date fixed for redemption; provided, that
payment of interest becoming due on or prior to the date fixed for redemption
shall be payable in the case of Subordinated Securities with Coupons attached
thereto, to the Holders of the Coupons for such interest upon surrender thereof,
and in the case of Registered Subordinated Securities, to the Holder of such
Registered Subordinated Securities registered as such on the relevant record
date, subject to the terms and provisions of Section 2.03 and 2.07 hereof.

     If any Subordinated Security called for redemption shall not be so paid
upon surrender thereof for redemption, the principal shall, until paid or duly
provided for, bear interest from the date fixed for redemption at the rate of
interest or Yield to Maturity (in the case of an Original Issue Discount
Subordinated Security) borne by such Subordinated Security.

                                       25
<PAGE>

     If any Subordinated Security with Coupons attached thereto is surrendered
for redemption and is not accompanied by all appurtenant Coupons maturing after
the date fixed for redemption, the surrender of such missing Coupon or Coupons
may be waived by the Company and the Trustee, if there be furnished to each of
them such security or indemnity as they may require to save each of them
harmless.

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

     SECTION 3.04.  Exclusion of Certain Subordinated Securities From
                    -------------------------------------------------
Eligibility for Selection for Redemption.  Subordinated Securities shall be
----------------------------------------
excluded from eligibility for selection for redemption if they are identified by
registration and certificate number in an Officer's Certificate delivered to the
Trustee at least 40 days prior to the last date on which notice of redemption
may be given as being owned of record and beneficially by, and not pledged or
hypothecated by, either (a) the Company or (b) an entity specifically identified
in such written statement as directly or indirectly controlling or controlled by
or under direct or indirect common control with the Company.

     SECTION 3.05.  Mandatory and Optional Sinking Funds.  The minimum amount of
                    ------------------------------------
any sinking fund payment provided for by the terms of the Subordinated
Securities of any series is herein referred to as a "mandatory sinking fund
payment," and any payment in excess of such minimum amount provided for by the
terms of the Subordinated Securities of any series herein referred to as an
"optional sinking fund payment."  The date on which a sinking fund payment is to
be made is herein referred to as the "sinking fund payment date."

     In lieu of making all or any part of any mandatory sinking fund payment
with respect to any series of Subordinated Securities in cash, the Company may
at its option (a) deliver to the Trustee Subordinated Securities of such series
theretofore purchased or otherwise acquired (except upon redemption pursuant to
the mandatory sinking fund) by the Company or receive credit for Subordinated
Securities of such series (not previously so credited) theretofore purchased or
otherwise acquired (except as aforesaid) by the Company and delivered to the
Trustee for cancellation pursuant to Section 2.10, (b) receive credit for
optional sinking fund payments (not previously so credited) made pursuant to
this Section, or (c) receive credit for Subordinated Securities of such series
(not previously so credited) redeemed by the Company through any optional
redemption provision contained in the terms of such series.  Subordinated
Securities so delivered or credited shall be received or credited by the Trustee
at the sinking fund redemption price specified in such Subordinated Securities.

     On or before the 60th day next preceding each sinking fund payment date for
any series, the Company will deliver to the Trustee an Officer's Certificate
(which need not contain the statements required by Section 13.03) (a) specifying
the portion of the mandatory sinking fund payment to be satisfied by payment of
cash and the portion to be satisfied by credit of Subordinated Securities of
such series and the basis for such credit, (b) stating that none of the
Subordinated Securities of such series has theretofore been so credited, (c)
stating that no

                                       26
<PAGE>

defaults in the payment of interest or Events of Default with respect to such
series have occurred (which have not been waived or cured) and are continuing
and (d) stating whether or not the Company intends to exercise its right to make
an optional sinking fund payment with respect to such series and, if so,
specifying the amount of such optional sinking fund payment which the Company
intends to pay on or before the next succeeding sinking fund payment date. Any
Subordinated Securities of such series to be credited and required to be
delivered to the Trustee in order for the Company to be entitled to credit
therefor as aforesaid which have not theretofore been delivered to the Trustee
shall be delivered for cancellation pursuant to Section 2.10 to the Trustee with
such Officer's Certificate (or reasonably promptly thereafter if acceptable to
the Trustee). Such Officer's Certificate shall be irrevocable and upon its
receipt by the Trustee the Company shall become unconditionally obligated to
make all the cash payments or payments therein referred to, if any, on or before
the next succeeding sinking fund payment date. Failure of the Company, on or
before any such 60th day, to deliver such Officer's Certificate and Subordinated
Securities specified in this paragraph, if any, shall not constitute a default
but shall constitute, on and as of such date, the irrevocable election of the
Company (i) that the mandatory sinking fund payment for such series due on the
next succeeding sinking fund payment date shall be paid entirely in cash without
the option to deliver or credit Subordinated Securities of such series in
respect thereof and (ii) that the Company will make no optional sinking fund
payment with respect to such series as provided in this Section.

     If the sinking fund payment or payments (mandatory or optional or both) to
be made in cash on the next succeeding sinking fund payment date plus any unused
balance of any preceding sinking fund payments made in cash shall exceed $50,000
(or the equivalent thereof in any Foreign Currency or ECU) or a lesser sum in
United States Dollars (or the equivalent thereof in any Foreign Currency or ECU)
if the Company shall so request with respect to the Subordinated Securities of
any particular series, such cash shall be applied on the next succeeding sinking
fund payment date to the redemption of Subordinated Securities of such series at
the sinking fund redemption price together with accrued interest to the date
fixed for redemption.  If such amount shall be $50,000 (or the equivalent
thereof in any Foreign Currency or ECU) or less and the Company makes no such
request then it shall be carried over until a sum in excess of $50,000 (or the
equivalent thereof in any Foreign Currency or ECU) is available.  The Trustee
shall select, in the manner provided in Section 3.02, for redemption on such
sinking fund payment date a sufficient principal amount of Subordinated
Securities of such series to absorb said cash, as nearly as may be, and shall
(if requested in writing by the Company) inform the Company of the serial
numbers of the Subordinated Securities of such series (or portions thereof) so
selected.  Subordinated Securities shall be excluded from eligibility for
redemption under this Section if they are identified by registration and
certificate number in an Officer's Certificate delivered to the Trustee at least
60 days prior to the sinking fund payment date as being owned of record and
beneficially by, and not pledged or hypothecated by, either (a) the Company or
(b) an entity specifically identified in such Officer's Certificate as directly
or indirectly controlling or controlled by or under direct or indirect common
control with the Company.  The Trustee, in the name and at the expense of the
Company (or the Company, if it shall so request the Trustee in writing) shall
cause notice of redemption of the Subordinated Securities of such series to be
given in substantially the manner provided in Section 3.02 (and with the effect
provided in Section 3.03) for the redemption of Subordinated Securities of such
series in part at the option of the Company.  The amount of any sinking fund
payments not so applied or allocated to the redemption of Subordinated
Securities of such series shall be added to

                                       27
<PAGE>

the next cash sinking fund payment for such series and, together with such
payment, shall be applied in accordance with the provisions of this Section. Any
and all sinking fund moneys held on the Stated Maturity date of the Subordinated
Securities of any particular series (or earlier, if such maturity is
accelerated), which are not held for the payment or redemption of particular
Subordinated Securities of such series shall be applied, together with other
moneys, if necessary, sufficient for the purpose, to the payment of the
principal of, and interest on, the Subordinated Securities of such series at its
Stated Maturity.

     On or before each sinking fund payment date, the Company shall pay to the
Trustee in cash or shall otherwise provide for the payment of all interest
accrued to the date fixed for redemption on Subordinated Securities to be
redeemed on the next following sinking fund payment date.

     The Trustee shall not redeem or cause to be redeemed any Subordinated
Securities of a series with sinking fund moneys or give any notice of redemption
of Subordinated Securities for such series by operation of the sinking fund
during the continuance of a default in payment of interest on such Subordinated
Securities or of any Event of Default except that, where the giving of notice of
redemption of any Subordinated Securities shall theretofore have been made, the
Trustee shall redeem or cause to be redeemed such Subordinated Securities,
provided that it shall have received from the Company a sum sufficient for such
redemption.  Except as aforesaid, any moneys in the sinking fund for such series
at the time when any such default or Event of Default shall occur, and any
moneys thereafter paid into the sinking fund, shall, during the continuance of
such default or Event of Default be deemed to have been collected under Article
5 and held for the payment of all such Subordinated Securities.  In case such
Event of Default shall have been waived as provided in Section 6.09 or the
default cured on or before the sixtieth day preceding the sinking fund payment
date in any year, such moneys shall thereafter be applied on the next succeeding
sinking fund payment date in accordance with this Section to the redemption of
such Subordinated Securities.

                                 ARTICLE FOUR

                      PARTICULAR COVENANTS OF THE COMPANY

     SECTION 4.01.  Payment of Principal of and Interest on Subordinated
                    ----------------------------------------------------
Securities.  The Company covenants that it will duly and punctually pay or cause
----------
to be paid the principal of and any interest and premium on each of the
Subordinated Securities in accordance with the terms of the Subordinated
Securities and in the Coupons, if any, appertaining thereto and this
Subordinated Indenture.  Except with respect to any Registered Global
Subordinated Securities, if the Subordinated Securities of any series bear
interest, each installment of interest on the Subordinated Securities of such
series may, at the option of the Company, be paid by mailing a check or checks
for such interest payable to the Person entitled thereto pursuant to Section
2.07 to the address of such Person as it appears on the Register of such series
on the applicable Record Date for such interest payment.  The interest on
Securities with Coupons attached (together with any additional amounts payable
pursuant to the terms of such Securities) shall be payable only upon
presentation and surrender of the several Coupons for such interest installments
as are evidenced thereby as they severally mature.  If any temporary
Unregistered Security provides that interest thereon may be paid while such
Security is in temporary form, the

                                       28
<PAGE>

interest on any such temporary Unregistered Security (together with any
additional amounts payable pursuant to the terms of such Security) shall be
paid, as to the installments of interest evidenced by Coupons attached thereto,
if any, only upon presentation and surrender thereof, and, as to the other
installments of interest, if any, only upon presentation of such Securities for
notation thereon of the payment of such interest, in each case subject to any
restrictions that may be established pursuant to Section 2.03. The interest, if
any, on Registered Securities (together with any additional amounts payable
pursuant to the terms of such Securities) shall be payable only to or upon the
written order of the Holders thereof and, at the option of the Company, may be
paid by wire transfer or by mailing checks for such interest payable to or upon
the written order of such Holders at their last addresses as they appear on the
Register of the Company.

     SECTION 4.02.  Corporate Existence of the Company; Consolidation, Merger,
                    ----------------------------------------------------------
Sale or Transfer. The Company covenants that so long as any of the Subordinated
----------------
Securities are Outstanding, it will maintain its existence, will not dissolve,
sell or otherwise dispose of all or substantially all of its assets and will not
consolidate with or merge into another entity or permit one or more other
entities to consolidate with or merge into it; provided that the Company may,
without violating the covenants in this Section 4.02 contained, consolidate with
or merge into another entity or permit one or more other entities to consolidate
with or merge into it, or sell or otherwise transfer to another entity all or
substantially all of its assets as an entirety and thereafter dissolve, if the
surviving, resulting or transferee entity, as the case may be, (i) shall be
organized and existing under the laws of one of the States of the United States
of America, (ii) assumes, if such entity is not the Company, all of the
obligations of the Company hereunder and (iii) is not, after such transaction,
otherwise in default under any provisions hereof.

     SECTION 4.03.  Maintenance of Offices or Agencies for Transfer,
                    ------------------------------------------------
Registration, Exchange and Payment of Subordinated Securities.  So long as any
-------------------------------------------------------------
of the Subordinated Securities shall remain Outstanding, the Company covenants
that it will cause the Trustee to maintain an office or agency in either The
City of [New York, State of New York], or the City and County of San Francisco,
State of California, where the Subordinated Securities may be presented for
registration, exchange and transfer as in this Subordinated Indenture provided,
and where notices and demands to or upon the Trustee in respect of the
Subordinated Securities or of this Subordinated Indenture may be served, and
where the Subordinated Securities may be presented for payment.  In case the
Trustee shall fail to maintain any such office or agency, presentations and
demands may be made and notices may be served at the principal office of the
Company.

     The Company will maintain one or more agencies in a city or cities located
outside the United States (including any city in which such an agency is
required to be maintained under the rules of any stock exchange on which the
Securities of any series are listed) where the Unregistered Securities, if any,
of each series and Coupons, if any, appertaining thereto may be presented for
payment.  No payment on any Unregistered Security or Coupon will be made upon
presentation of such Unregistered Security or Coupon at an agency of the Company
within the United States nor will any payment be made by transfer to an account
in, or by mail to an address in, the United States unless, pursuant to
applicable United States laws and regulations then in effect, such payment can
be made without adverse tax consequences to the Company.  Notwithstanding the
foregoing, if full payment in United States Dollars at each agency maintained by
the Company outside the United States for payment on such Unregistered

                                       29
<PAGE>

Securities or Coupons appertaining thereto is illegal or effectively precluded
by exchange controls or other similar restrictions, payments in United States
Dollars of Unregistered Securities of any series and coupons appertaining
thereto which are payable in United States Dollars may be made at an agency of
the Company maintained in the City of New York.

     The Company will maintain in the Borough of Manhattan, The City of New
York, an office or agency where notices and demands to or upon the Company in
respect of the Subordinated Securities of any series, the Coupons appertaining
thereto or this Subordinated Indenture may be served.

     The Company will give to the Trustee written notice of the location of each
such office or agency and of any change of location thereof.  In case the
Company shall fail to maintain any agency required by this Section to be located
in the Borough of Manhattan, The City of New York or the City and County of San
Francisco, or shall fail to give such notice of the location or for any change
in the location of any of the above agencies, presentations and demands may be
made and notices may be served at the Principal Office of the Trustee.

     The Company may from time to time designate one or more additional offices
or agencies where the Subordinated Securities of a series and any Coupons
appertaining thereto may be presented for payment, where the Subordinated
Securities of that series may be presented for exchange as provided in this
Subordinated Indenture and pursuant to Section 2.04 and where the Registered
Subordinated Securities of that series may be presented for registration of
transfer as in this Subordinated Indenture provided, and the Company may from
time to time rescind any such designation, as the Company may deem desirable or
expedient; provided, that no such designation or rescission shall in any manner
relieve the Company of its obligations to maintain the agencies provided for in
this Section.  The Company shall give to the Trustee prompt written notice of
any such designation or rescission thereof.

     SECTION 4.04.  Appointment to Fill a Vacancy in the Office of Trustee. The
                    ------------------------------------------------------
Company, whenever necessary to avoid or fill a vacancy in the office of Trustee,
covenants that it will appoint, in the manner provided in Section 7.10, a
Trustee, so that there shall at all times be a Trustee with respect to the
Outstanding Subordinated Securities.

     SECTION 4.05.  Duties of Paying Agent.  (a)  If the Company shall appoint a
                    ----------------------
Paying Agent other than the Trustee with respect to Subordinated Securities of
any series, it will cause such Paying Agent to execute and deliver to the
Trustee an instrument in which such agent shall agree with the Trustee, subject
to the provisions of this Section 4.05 and Section 11.04,

          (1) that it will hold all sums held by it as such agent for the
payment of the principal of or interest, if any, on the Subordinated Securities
of such series (whether such sums have been paid to it by the Company or by any
other obligor on the Subordinated Securities of such series) in trust for the
benefit of the Holders of the Subordinated Securities entitled to such principal
or interest and will notify the Trustee of the receipt of sums to be so held,

          (2) that it will give the Trustee notice of any failure by the Company
(or by any other obligor on the Subordinated Securities of such series) to make
any payment of the

                                       30
<PAGE>

principal of or interest on the Subordinated Securities of such series when the
same shall be due and payable, and

         (3) that it will at any time during the continuance of any Event of
Default, upon the written request of the Trustee, deliver to the Trustee all
sums so held in trust by it.

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

     (c) If the Company shall act as its own Paying Agent with respect to the
Subordinated Securities of any series, it will, on or before each due date of
the principal of or interest on the Subordinated Securities of such series, set
aside, segregate and hold in trust for the benefit of the Holders of the
Subordinated Securities of such series or the Coupons appertaining thereto a sum
sufficient to pay such principal or interest so becoming due.  The Company will
promptly notify the Trustee of any failure to take such action.

     (d) Anything in this Section 4.05 to the contrary notwithstanding, the
Company may, at any time, for the purpose of obtaining a satisfaction and
discharge of this Subordinated Indenture with respect to one or more or all
series of Subordinated Securities hereunder, or for any other reason, pay or
cause to be paid to the Trustee all sums held in trust for such series by it, or
any Paying Agent hereunder, as required by this Section 4.05, and such sums are
to be held by the Trustee upon the trust herein contained.

     SECTION 4.06.  Notice of Default.  The Company covenants that, as soon as
                    -----------------
is practicable, the Company will furnish the Trustee notice of any event which
is an Event of Default or which with the giving of notice or the passage of time
or both would constitute an Event of Default which has occurred and is
continuing on the date of such notice, which notice shall set forth the nature
of such event and the action which the Company proposes to take with respect
thereto.

     SECTION 4.07.  Maintenance of Properties.  The Company will cause all
                    -------------------------
properties used in or useful in the conduct of its business to be maintained and
kept in good condition, repair, and working order and supplied with all
necessary equipment and will cause to be made all necessary repairs, renewals,
replacements, betterments and improvements thereof, all as in the judgment of
the Company may be necessary, so that the business carried on in connection
therewith may be properly and advantageously conducted at all time except to the
extent that the Company may be prevented from so doing by circumstances beyond
its control; provided, that nothing in this Section shall prevent the Company
from discontinuing the operation or maintenance of any of such properties, or
disposing of any of them, if such discontinuance or disposal is, in the judgment
of the Company desirable in the conduct of the business of the Company and not
disadvantageous in any material respect to the Subordinated Securityholders.

                                       31
<PAGE>

     SECTION 4.08.  Payment of Taxes and Other Claims.  The Company will pay or
                    ---------------------------------
discharge or cause to be paid or discharged, before the same shall become
delinquent:  (a) all taxes, assessments and governmental charges levied or
imposed upon the Company or upon the income, profits or property of the Company;
and (b) all lawful claims for labor, materials, and supplies, which, if unpaid,
might by law become a lien upon the property of the Company; provided, that the
Company shall not be required to pay or discharge or cause to be paid or
discharged any such tax, assessment, charge or claim whose amount, applicability
or validity is being contested in good faith by appropriate proceedings; and
provided further that the Company shall not be required to cause to be paid or
discharged any such tax, assessment, charge or claim if the Company shall
determine that such payment is not advantageous to the conduct of the business
of the Company taken as a whole and that the failure so to pay or discharge is
not disadvantageous in any material respect to the Subordinated Securityholders.

     SECTION 4.09.  Luxembourg Publications.  In the event of the publication of
                    -----------------------
any notice pursuant to Section 3.02, 6.10, 7.10(a), 7.11 and 10.02, the party
making such publication in the Borough of Manhattan, The City of New York and
London shall also, to the extent that notice is required to be given to Holders
of Subordinated Securities of any series by applicable Luxembourg law or stock
exchange regulation, as evidenced by an Officer's Certificate delivered to such
party, make a similar publication in Luxembourg.

                                  ARTICLE FIVE


                SUBORDINATED SECURITYHOLDERS' LISTS AND REPORTS
                         BY THE COMPANY AND THE TRUSTEE

     SECTION 5.01.  Company to Furnish Trustee Information as to the Names and
                    ----------------------------------------------------------
Addresses of Subordinated Securityholders.  The Company will furnish or cause to
-----------------------------------------
be furnished to the Trustee, not less than 45 days nor more than 60 days after
each date (month and day) specified as an Interest Payment Date for the
Subordinated Securities of the first series issued under this Subordinated
Indenture (whether or not any Subordinated Securities of that series are then
Outstanding), but in no event less frequently than semiannually, and at such
other times as the Trustee may request in writing, within 30 days after receipt
by the Company of any such request, a list in such form as the Trustee may
reasonably require containing all the information in the possession or control
of the Company, or any of its Paying Agents other than the Trustee, as to the
names and addresses of the Holders of Subordinated Securities, obtained since
the date as of which the next previous list, if any, was furnished, excluding
from any such list the names and addresses received by the Trustee in its
capacity as registrar (if so acting).  Any such list may be dated as of a date
not more than 15 days prior to the time such information is furnished and need
not include information received after such date.

     SECTION 5.02.  Preservation of Information; Communication to Subordinated
                    ----------------------------------------------------------
Securityholders.  (a)  The Trustee shall preserve, in as current a form as is
---------------
reasonably practicable, the names and addresses of the Holders of Subordinated
Securities of each series (1) contained in the most recent list furnished to it
as provided in Section 5.01, (2) received by the Trustee in the capacity of
Paying Agent or registrar (if so acting) and (3) filed with the Trustee within
the two preceding years as provided for in Section 5.04(c).  The Trustee may

<PAGE>

     (b)  If three or more Holders of Subordinated Securities (hereinafter
referred to as "applicants") apply in writing to the Trustee, and furnish to the
Trustee reasonable proof that each such applicant has owned a Subordinated
Security for a period of at least six months preceding the date of such
application, and such application states that the applicants desire to
communicate with other Holders of Subordinated Securities of any series or with
Holders of all Subordinated Securities with respect to their rights under this
Subordinated Indenture or under such Subordinated Securities, and is accompanied
by a copy of the form of proxy or other communication which such applicants
propose to transmit, then the Trustee shall, within five Business Days after the
receipt of such application, at its election, either:

          (1) afford such applicants access to the information preserved at the
time by the Trustee in accordance with the provisions of subsection (a) of this
Section 5.02; or

          (2) inform such applicants as to the approximate number of Holders of
Subordinated Securities of such series or all Subordinated Securities, as the
case may be, whose names and addresses appear in the information preserved at
the time by the Trustee in accordance with the provisions of subsection (a) of
this Section 5.02, and as to the approximate cost of mailing to such
Subordinated Securityholders the form of proxy or other communications, if any,
specified in such application.

     If the Trustee shall elect not to afford such applicants access to such
information, the Trustee shall, upon the written request of such applicants,
mail to each of the Holders of Subordinated Securities of such series, or all
Subordinated Securities, as the case may be, whose name and address appear in
the information preserved at the time by the Trustee in accordance with the
provisions of subsection (a) of this Section 5.02, a copy of the form of proxy
or other communication which is specified in such request, with reasonable
promptness after a tender to the Trustee of the material to be mailed and of
payment, or provision for the payment, of the reasonable expenses of mailing,
unless within five days after such tender, the Trustee shall mail to such
applicants and file with the Commission, together with a copy of the material to
be mailed, a written statement to the effect that, in the opinion of the
Trustee, such mailing would be contrary to the best interests of the Holders of
Subordinated Securities of such series or all Subordinated Securities, as the
case may be, or would be in violation of applicable law.  Such written statement
shall specify the basis of such opinion.  If the Commission, after opportunity
for a hearing upon the objections specified in the written statement so filed,
shall enter an order refusing to sustain any of such objections or if, after the
entry of an order sustaining one or more of such objections, the Commission
shall find, after notice and opportunity for hearing, that all the objections so
sustained have been met and shall enter an order so declaring, the Trustee shall
mail copies of such material to all such Subordinated Securityholders with
reasonable promptness after the entry of such order and the renewal of such
tender; otherwise the Trustee shall be relieved of any obligation or duty to
such applicants respecting their application.

     (c)  Each and every Holder of the Subordinated Securities, by receiving and
holding the same, agrees with the Company and the Trustee that neither the
Company nor the Trustee nor any Paying Agent nor any registrar shall be held
accountable by reason of the disclosure of any such information as to the names
and addresses of the Holders of Subordinated Securities in accordance with the
provisions of subsection (b) of this Section 5.02, regardless of the source

                                       33
<PAGE>

from which such information was derived, and that the Trustee shall not be held
accountable by reason of mailing any material pursuant to a request made under
said subsection (b).

     SECTION 5.03.  Reports by Company.  (a)  The Company covenants and agrees
                    ------------------
to file with the Trustee within 15 days after the Company is required to file
the same with the Commission, copies of the annual reports and of the
information, documents and other reports (or copies of such portions of any of

mean any one of the following events:

     (a)  default in the payment of any installment of interest on any
Subordinated Security of such series as and when the same shall become due and
payable, and continuance of such default for a period of 30 days provided
however, that an extension of one or more Interest Payment Dates by the Company
in accordance with the provisions of any Supplemental Subordinated Indenture,
shall not constitute an Event of Default; or

     (b)  default in the payment of all or any part of the principal of or any
premium on any Subordinated Security of such series as and when the same shall
become due and payable whether at maturity, by proceedings for redemption, by

Maturity for payment of principal of Subordinated Securities of such series in
accordance with the provisions of any Supplemental Subordinated Indenture, shall
not constitute an Event of Default; or

     (c)  default in the satisfaction of any sinking fund payment obligation
relating to such series of Subordinated Securities, when and as such obligation
shall become due and payable provided however, that an extension of the Stated
Maturity for payment of any sinking fund payment with respect to Subordinated
Securities of such series in accordance with the provisions of any Supplemental
Subordinated Indenture, shall not constitute an Event of Default; or

     (d)  failure on the part of the Company to observe or perform in any
material respect any other of the covenants or agreements on its part in the
Subordinated Securities or in this Subordinated Indenture (including any
Supplemental Subordinated Indenture or pursuant to any Officer's Certificate, as
contemplated by Section 2.03) specifically contained for the benefit of the
Holders of the Subordinated Securities of such series, for a period of 60 days
after there has been given, by registered or certified mail, to the Company by
the Trustee, or to the Company and the Trustee by the Holders of not less than
25% in principal amount of the Subordinated Securities of such series and all
other series so benefited (all series voting as one class) at the time
Outstanding under this Subordinated Indenture a written notice specifying such
failure and stating that such is a "Notice of Default" hereunder; or

                                       36
<PAGE>

     (e)  the entry by a court having jurisdiction in the premises of a decree
or order for relief in respect of the Company in an involuntary case under any
applicable bankruptcy, insolvency or other similar law now or hereafter in
effect, or appointing a receiver, liquidator, assignee, custodian, trustee,
sequestrator (or similar official) of the Company or for any substantial part of
its property, or ordering the winding up or liquidation of its affairs, if such
decree or order shall remain unstayed and in effect for a period of 60
consecutive days; or

     (f)  the commencement by the Company of a voluntary case under any

benefit of creditors, or its failure generally to pay its debts as they become
due or the taking by the Company of any corporate action in furtherance of any
of the foregoing; or

     (g)  any other Event of Default provided in the Officer's Certificate or
Supplemental Subordinated Indenture under which such series of Subordinated is
issued or in the form of Subordinated Security for such series.

     If an Event of Default described in clause (a), (b) or (c) shall have
occurred and be continuing with respect to any one or more series of Outstanding
Subordinated Securities, then and in each and every such case, unless the
principal amount of all the Subordinated Securities of each series as to which
there is an Event of Default shall have already become due and payable, either
the Trustee or the Holders of not less than 25% in principal amount of the
Subordinated Securities of such series then Outstanding hereunder (each such
series voting as a separate class) by notice in writing to the Company (and to
the Trustee if given by Subordinated Securityholders) may declare the principal
amount (or, if the Subordinated Securities of any such series are Original Issue
Discount Subordinated Securities, such portion of the principal amount as may be
specified in the terms of such series) of all the Subordinated Securities of
such series, together with any accrued interest, to be due and payable
immediately, and upon any such declaration the same shall be immediately due and
payable, anything in this Subordinated Indenture or in the Subordinated
Securities of such series contained to the contrary notwithstanding.

     Except as otherwise provided in the terms of any series of Subordinated
Securities pursuant to Section 2.03, if an Event of Default described in clause
(d) or (g) above with respect to all series of Subordinated Securities then
Outstanding, occurs and is continuing, then, and in each and every such case,
unless the principal of all of the Subordinated Securities shall have already
become due and payable, either the Trustee or the Holders of not less than 25%
in aggregate principal amount of all of the Subordinated Securities then
Outstanding hereunder (treated as one class) by notice in writing to the Company
(and to the Trustee if given by Securityholders), may declare the entire
principal (or, if the Subordinated Securities of any series are Original Issue
Discount Securities, such portion of the principal amount as may be specified in
the terms of such series) of all of the Subordinated Securities then
Outstanding, and the interest accrued thereon, if any, to be due and payable
immediately, and upon such declaration, the same shall become immediately due
and payable.  If an Event of Default described in

                                       37
<PAGE>

clause (e) or (f) above occurs and is continuing, then the principal amount of
all of the Subordinated Securities then Outstanding, and the interest accrued
thereon, if any, shall become and be immediately due and payable without any
declaration or other act on the part of the Trustee or any Holder.

     If an Event of Default described in clause (d) or (g) occurs and is
continuing, which Event of Default is with respect to less than all series of
Subordinated Securities then Outstanding, then, and in each and every such case,
except for any series of Subordinated Securities the principal of which shall
have already become due and payable, either the Trustee or the Holders of not
less than 25% in aggregate principal amount of the Subordinated Securities of
each such affected series then Outstanding hereunder (each such series voting as
a separate class) by notice in writing to the Company (and to the Trustee if
given by Securityholders), may declare the entire principal (or, if the
Securities of such series are Original Issue Discount Securities, such portion
of the principal amount as may be specified in the terms of such series) of all
Securities of such series, and the interest accrued thereon, if any, to be due
and payable immediately, and upon any such declaration, the same shall become
immediately due and payable.

     The foregoing provisions, however, are subject to the condition that if, at
any time after the principal amount (or, if the Subordinated Securities are
Original Issue Discount Subordinated Securities, such portion of the principal
as may be specified in the terms thereof of the Subordinated Securities of any
one or more series (or of all the Subordinated Securities, as the case may be)
shall have been so declared due and payable, and before any judgment or decree
for the payment of moneys due shall have been obtained or entered as hereinafter
provided, the Company shall pay or shall deposit with the Trustee a sum
sufficient to pay all matured installments of interest upon all the Subordinated
Securities of such series (or upon all the Subordinated Securities, as the case
may be) and the principal of any and all Subordinated Securities of such series
(or of any and all the Subordinated Securities, as the case may be) which shall
have become due otherwise than by declaration (with interest on overdue
installments of interest to the extent permitted by law and on such principal at
the rate or rates of interest borne by, or prescribed therefor in the
Subordinated Securities of such series to the date of such payment or deposit)
and interest upon such principal and, to the extent that payment of such
interest is enforceable under applicable law, on overdue installments of
interest, at the same rate as the rate of interest or Yield to Maturity (in the
case of Original Issue Discount Securities) specified in the Securities of such
series (or at the respective rates of interest or Yields to Maturity of all the
Securities, as the case may be) to the date of such payment or deposit; and the
amounts payable to the Trustee under Section 7.06 and any and all defaults under
the Subordinated Indenture with respect to Subordinated Securities of such
series (or all Subordinated Securities, as the case may be), other than the non-
payment of principal of and any accrued interest on Subordinated Securities of
such series (or any Subordinated Securities, as the case may be) which shall
have become due by declaration shall have been cured, remedied or waived as
provided in Section 6.09 -- then and in every such case the Holders of a
majority in principal amount of the Subordinated Securities of such series (or
of all the Subordinated Securities, as the case may be) then Outstanding (such
series or all series voting as one class if more than one series are so
entitled) by written notice to the Company and to the Trustee, may rescind and
annul such declaration and its consequences; but no such rescission and
annulment

                                       38
<PAGE>

shall extend to or shall affect any subsequent default, or shall impair any
right consequent thereon.

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

     In case the Trustee shall have proceeded to enforce any right under this
Subordinated Indenture and such proceedings shall have been discontinued or
abandoned because of such rescission or annulment or for any other reason or
shall have been determined adversely to the Trustee, then and in every such case
the Company, the Trustee and the Holders of the Subordinated Securities of such
series (or of all the Subordinated Securities, as the case may be) shall be
restored respectively to their former positions and rights hereunder, and all
rights, remedies and powers of the Company and the Trustee and the Holders of
the Subordinated Securities of such series (or of all the Subordinated
Securities, as the case may be) shall continue as though no such proceedings had
been taken.

                    ---------------------------------------------------------
Subordinated Securities on Default in Payment of Interest or Principal.  The
----------------------------------------------------------------------
Company covenants that:

          (a) in case default shall be made in the payment of any installment of
interest on any of the Subordinated Securities of any series as and when the
same shall become due and payable and which payment has not been extended in
accordance with the provisions of  a Supplemental Subordinated Indenture, and
such default shall have continued for a period of 30 days; or

          (b) in case default shall be made in the payment of all or any part of
the principal of any of the Subordinated Securities of any series when the same
shall have become due and payable and which payment has not been extended in
accordance with the provisions of  a Supplemental Subordinated Indenture,
whether at the Stated Maturity of such series or by any call for redemption or
by declaration of acceleration or otherwise; or

          (c) in case default shall be made in the satisfaction of any sinking
fund obligation when and as such obligation becomes due and payable and which
payment has not been extended in accordance with the provisions of a
Supplemental Subordinated Indenture, upon demand of the Trustee, the Company
will pay to the Trustee, for the benefit of the Holders of the Subordinated
Securities of such series, the whole amount that then shall have become due and
payable on all such Subordinated Securities of such series and such Coupons, for
principal (and any premium) and interest and for any overdue sinking fund
payment together with interest upon the overdue principal and installments of
interest (to the extent permitted by law) at the rate

                                       39
<PAGE>

or rates of interest borne by or Yield to Maturity (in the case of Original
Issue Discount Subordinated Securities), or prescribed therefor in, the
Subordinated Securities of such series; and, in addition thereto, such further
amount as shall be sufficient to cover the costs and expense of collection,
including a reasonable compensation to the Trustee, its agents and counsel, and
any expenses or liabilities incurred, and all advances made, by the Trustee
hereunder other than through its negligence or bad faith.

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

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

     SECTION 6.03.  Trustee May File Proofs of Claim.  In case of the pendency
                    --------------------------------
of any receivership, insolvency, liquidation, bankruptcy, reorganization,
arrangement, adjustment, composition or other similar judicial proceeding
relative to the Company or any other obligor upon the Subordinated Securities or
the property of the Company or of such other obligor or their creditors, the
Trustee (irrespective of whether the principal of the Subordinated Securities of
any series shall then be due and payable as therein expressed or by declaration
or otherwise and irrespective of whether the Trustee shall have made any demand
on the Company for the payment of overdue principal or interest) shall be
entitled and empowered, to the fullest extent permitted by law, by intervention
in such proceeding or otherwise:

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

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

                                       40
<PAGE>

and any custodian, receiver, assignee, trustee, liquidator, sequestrator or
other similar official in any such judicial proceeding is hereby authorized by
each Holder to make such payments to the Trustee and, in the event that the
Trustee shall consent to the making of such payments directly to the Holders, to
pay to the Trustee any amount due it for the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, and any other
amounts due the Trustee under Section 7.06.

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

Subordinated Indenture or the Subordinated Securities of any series or Coupons
appertaining to such Subordinated Securities, may be prosecuted and enforced by
the Trustee to the fullest extent permitted by law without the possession of any
of the Subordinated Securities of any series or Coupons appertaining to such
Subordinated Securities, or the production thereof in any proceeding relating
thereto, and any such proceeding instituted by the Trustee shall be brought in
its own name as trustee of an express trust, and any recovery of judgment shall,
after provision for the payment of the reasonable compensation, expenses,
disbursements and advances of the Trustee, its agents and counsel, be for the
ratable benefit of the Holders of the Subordinated Securities or Coupons in
respect of which such judgment has been recovered.

     SECTION 6.05.  Application of Moneys Collected by Trustee.  Any moneys
                    ------------------------------------------
collected by the Trustee pursuant to Section 6.02 shall be applied in the order
following, at the date or dates fixed by the Trustee for the distribution of
such moneys, upon presentation of the several Subordinated Securities or Coupons
appertaining to such Subordinated Securities in respect of which moneys have
been collected, and stamping thereon the payment, if only partially paid, and
upon surrender thereof if fully paid:

7.06;

          SECOND:  In case the principal of the Outstanding Subordinated
Securities in respect of which moneys have been collected shall not have become
due and be unpaid, to the payment of any interest on such Subordinated
Securities, in the order of the maturity of the installments of such interest,
with interest upon the overdue installments of interest (so far as permitted by
law and to the extent that such interest has been collected by the Trustee at
the rate or rates of interest borne by or Yield to Maturity (in the case of
Original Issue Discount Subordinated Securities) of such Subordinated Securities
or prescribed therefor therein) such payments to be made ratably to the Persons
entitled thereto, without discrimination or preference;

          THIRD:  In case the principal of the Outstanding Subordinated
Securities in respect of which such moneys have been collected shall have become
due, by declaration or otherwise, to the payment of the whole amount then owing
and unpaid upon such Subordinated

<PAGE>

Securities for principal and interest, if any, with interest on the overdue
principal and any installments of interest (so far as permitted by law and to
the extent that such interest has been collected by the Trustee) at the rate or
rates of interest borne by or Yield to Maturity (in the case of Original Issue
Discount Subordinated Securities), or prescribed therefor in, such Subordinated
Securities; and in case such moneys shall be insufficient to pay in full the
whole amount so due and unpaid upon such Subordinated Securities, then to the
payment of such principal and interest or Yield to Maturity, without preference
or priority of principal over interest or Yield to Maturity, or of interest or
Yield to Maturity over principal, or of any installment of interest over any
other installment of interest, or of any Subordinated Security over any other
Subordinated Security, ratably to the aggregate of such principal and accrued
and unpaid interest or Yield to Maturity; and

          FOURTH:  To the payment of the remainder, with appropriate interest to
the Company or its successors or assigns, or to whomsoever may be lawfully
entitled to receive the same, or as a court of competent jurisdiction may
direct.

     SECTION 6.06.  Limitation on Suits by Holders of Subordinated Securities.
                    ---------------------------------------------------------
No Holder of any Subordinated Security of any series or of any Coupon
appertaining thereto shall have any right by virtue or by availing of any
provision of this Subordinated Indenture to institute any suit, action or
proceeding in equity or at law upon or under or with respect to this
Subordinated Indenture or for the appointment of a receiver or trustee, or for
any other remedy hereunder, unless such Holder previously shall have given to
the Trustee written notice of a continuing Event of Default, as hereinbefore
provided, and unless also the Holders of not less than 25% in principal amount
of the Subordinated Securities of such series then Outstanding shall have made
written request upon the Trustee to institute such action, suit or proceeding in
its own name as Trustee hereunder and shall have offered to the Trustee such
reasonable indemnity as it may require against the costs, expenses and
liabilities to be incurred therein or thereby (including the reasonable fees of
counsel for the Trustee), and the Trustee, for 60 days after its receipt of such
notice, request and offer of indemnity, shall have neglected or refused to
institute any such action, suit or proceeding and no direction inconsistent with
such written request shall have been given to the Trustee pursuant to this
Section 6.06; it being understood and intended, and being expressly covenanted
by the taker and Holder of every Subordinated Security or Coupon with every
other taker and Holder and the Trustee, that no one or more Holders of
Subordinated Securities of any series or Coupons appertaining to such
Subordinated Securities shall have any right in any manner whatever by virtue or
by availing of any provision of this Subordinated Indenture to affect, disturb
or prejudice the rights of the Holders of any other of such Subordinated
Securities or Coupons appertaining to such Subordinated Securities, or to obtain
or seek to obtain priority over or preference to any other such Holder, or to
enforce any right under this Subordinated Indenture, except in the manner herein
provided and for the equal, ratable and common benefit of all Holders of
Subordinated Securities of the applicable series and Coupons appertaining to
such Subordinated Securities.  For the protection and enforcement of the
provisions of this Section 6.06, each and every Holder and the Trustee shall be
entitled to such relief as can be given either at law or in equity.

right of any Holder of any Subordinated Security or Coupon to receive payment of
the principal of and interest on such Subordinated Security or Coupon on or
after the respective due dates expressed

                                       42

date fixed for redemption), or to institute suit for the enforcement of any such
payment on or after such respective dates shall not be impaired or affected
without the consent of such Holder.

given by this Article Six to the Trustee or to the Holders shall, to the extent
permitted by law, be deemed cumulative and not exclusive of any thereof or of
any other powers and remedies available to the Trustee or the Holders, by
judicial proceedings or otherwise, to enforce the performance or observance of
the covenants and agreements contained in this Subordinated Indenture, and no
delay or omission of the Trustee or of any Holder of any of the Subordinated
Securities or Coupons to exercise any right or power accruing upon any default
occurring and continuing as aforesaid shall impair any such right or power, or
shall be construed to be a waiver of any such default or an acquiescence
therein; and, subject to the provisions of Section 6.06, every power and remedy
given by this Article Six or by law to the Trustee or to the Holders may be
exercised from time to time, and as often as shall be deemed expedient, by the
Trustee or by the Holders.  The assertion or employment of any right or remedy
hereunder or otherwise shall not prevent the concurrent assertion or employment
of any other appropriate right or remedy.

     SECTION 6.08.  Delay or Omission Not Waiver.  No delay or omission of the
                    ----------------------------
Trustee or of any Holder of any Subordinated Securities or Coupons to exercise
any right or remedy accruing upon any Event of Default shall impair any such
right or remedy or constitute a waiver of any such Event of Default or an
acquiescence therein.  Subject to the provisions of Section 6.06, every right
and remedy given by this Article Six or by law to the Trustee or to the Holders
may be exercised from time to time, and as often as may be deemed expedient, by
the Trustee or by the Holders, as the case may be.

     SECTION 6.09.  Control by Holders; Waiver of Past Defaults.  The Holders of
                    -------------------------------------------
a majority in principal amount of the Subordinated Securities of all series
(voting as one class) at the time Outstanding (determined as provided in Section
8.04) shall have the right to direct the time, method and place of conducting
any proceeding for any remedy available to the Trustee, or exercising any trust
or power conferred on the Trustee; provided, however, that, subject to Section
7.01 the Trustee shall have the right to decline to follow any such direction if
the Trustee in reliance upon an Opinion of Counsel determines that the action so
directed may not lawfully be taken, or if the Trustee in good faith shall, by a
Responsible Officer or Officers of the Trustee, determine that the proceedings
so directed would be illegal or involve it in personal liability or be unduly
prejudicial to the rights of Holders not parties to such direction, and provided
further that nothing in this Subordinated Indenture shall impair the right of
the Trustee to take any action deemed proper by the Trustee and which is not
inconsistent with such direction by the Holders.

     The Company may set a special record date for purposes of determining the
identity of the Holders of Subordinated Securities entitled to vote or consent
to any action by vote or consent authorized or permitted by this Section 6.09.
Such record date shall be the later of 15 days prior to the first solicitation
of such consent or the date of the most recent list of Holders furnished to the
Trustee pursuant to Section 5.01 of this Subordinated Indenture prior to such
solicitation.

                                       43
<PAGE>

     The Holders of not less than a majority in principal amount of the
Subordinated Securities of any series at the time Outstanding (determined as
provided in Section 8.04) may on behalf of the Holders of all the Subordinated
Securities of such series waive any past Event of Default with respect to such
series and its consequences (subject to Section 6.02), except a continuing Event
of Default specified in Section 6.01(a), (b) or (c), or in respect of a covenant
or provision of this Subordinated Indenture which under Article Ten cannot be
modified or amended without the consent of the Holder of each Subordinated
Security so affected.  Upon any such waiver, the Company, the Trustee and the
Holders of the Subordinated Securities of such series shall be restored to their
former positions and rights hereunder, respectively, and such Event of Default
shall be deemed to have been cured and not continuing for every purpose of this
Subordinated Indenture; but no such waiver shall extend to any subsequent or
other Event of Default or impair any right consequent thereon.

     SECTION 6.10.  Trustee to Give Notice of Defaults Known to it, but May
                    -------------------------------------------------------
Withhold in Certain Circumstances.  The Trustee shall, within 90 days after the
---------------------------------
occurrence of a default with respect to the Subordinated Securities of any
series, give notice of all defaults with respect to that series known to the
Trustee (i) if any Unregistered Subordinated Securities of that series are then
Outstanding, to the Holders thereof, by publication at least once in an
Authorized Newspaper in the Borough of Manhattan, The City of New York and at
least once in an Authorized Newspaper in London (and, if required by Section
4.09, at least once in an Authorized Newspaper in Luxembourg) and (ii) to all
Holders of Subordinated Securities of such series in the manner and to the
extent provided in Section 313(c) of the Trust Indenture Act, unless in each
case such defaults shall have been cured before the mailing or publication of
such notice (the term "default" for the purpose of this Section being hereby
defined to mean any event or condition which is, or with notice or lapse of time
or both would become, an Event of Default); provided, that, except in the case
of default in the payment of the principal of or interest on any of the
Subordinated Securities of such series, or in the payment of any sinking fund
installment on such series, the Trustee shall be protected in withholding such
notice if and so long as the board of directors, the executive committee, or a
trust committee of directors or trustees and/or Responsible Officers of the
Trustee in good faith determines that the withholding of such notice is in the
interests of the Subordinated Securityholders of such series.

     SECTION 6.11.  Requirement of an Undertaking to Pay Costs in Certain Suits
                    -----------------------------------------------------------
Under the Subordinated Indenture or Against the Trustee.  All parties to this
-------------------------------------------------------
Subordinated Indenture agree, and each Holder of any Subordinated Security by
such Holder's acceptance thereof shall be deemed to have agreed, that any court
may in its discretion require, in any suit for the enforcement of any right or
remedy under this Subordinated Indenture, or in any suit against the Trustee for
any action taken or omitted by it as Trustee, the filing by any party litigant
in such suit of an undertaking to pay the costs of such suit, and that such
court may in its discretion assess reasonable costs, including reasonable
attorneys' fees, against any party litigant in such suit, having due regard to
the merits and good faith of the claims or defenses made by such party litigant;
but the provisions of this Section 6.11 shall not apply to any suit instituted
by the Trustee, to any suit instituted by any Holder of Subordinated Securities
of any series, or group of such Holders, holding in the aggregate more than ten
percent in principal amount of the Subordinated Securities of such series
Outstanding, or to any suit instituted by any Holder for the enforcement of the
payment of the principal of or any interest or premium on any Subordinated

                                       44
<PAGE>

Security, on or after the due date expressed in such Subordinated Security or
for such interest (or in the case of any redemption, on or after the dated fixed
for redemption).

     SECTION 6.12.  Waiver of Stay, or Extension Laws.  The Company covenants
                    ---------------------------------
(to the extent that it may lawfully do so) that it will not at any time insist
upon, or plead, or in any manner whatsoever claim or take the benefit or
advantage of, any stay or extension law wherever enacted, now or at any time
hereinafter in force, which may affect the covenants or the performance of this
Indenture; and the Company (to the extent that it may lawfully do so) hereby
expressly waives all benefit or advantage of any such law and covenants that
they will not hinder, delay or impede the execution of any power herein granted
to the Trustee, but will suffer and permit the execution of every such power as
though no such law had been enacted.

                             CONCERNING THE TRUSTEE

     SECTION 7.01.  Certain Duties and Responsibilities of Trustee.  The
                    ----------------------------------------------
Trustee, prior to the occurrence of an Event of Default and after the curing,
remedying or waiving of all Events of Default which may have occurred,
undertakes to perform such duties and only such duties as are specifically set
forth in this Subordinated Indenture.  In case an Event of Default has occurred
(which has not been cured, remedied or waived), the Trustee shall exercise such
of the rights and powers vested in it by this Subordinated Indenture, and use
the same degree of care and skill in their exercise, as a prudent man would
exercise or use under the circumstances in the conduct of his or her own
affairs.

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

     (a)  prior to the occurrence of an Event of Default and after the curing,
remedying or waving of all Events of Default which may have occurred:

          (1) the duties and obligations of the Trustee shall be determined
solely by the express provisions of this Subordinated Indenture and the Trustee
shall not be liable except for the performance of such duties and obligations as
are specifically set forth in this Subordinated Indenture, and no implied
covenants or obligations shall be read into this Subordinated Indenture against
the Trustee; and

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

                                       45
<PAGE>

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

     (c)  the Trustee shall not be liable with respect to any action taken or
omitted to be taken by it in good faith in accordance with the direction of the
Holders of Subordinated Securities pursuant to Section 6.09 relating to the
time, method and place of conducting any proceeding for any remedy available to
the Trustee, or exercising any trust or power conferred upon the Trustee, under
this Subordinated Indenture.

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

     SECTION 7.02.  Certain Rights of Trustee.  Except as otherwise provided in
                    -------------------------
Section 7.01:

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

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

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

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

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

     (f)  The Trustee shall not be bound to make any investigation into the
facts or matters stated in any resolution, certificate, statement, instrument,
opinion, report, notice, request, consent, order, approval, bond, debenture,
note or other paper or document, unless requested in writing so to do by the
Holders of Subordinated Securities pursuant to Section 6.09; provided,

                                       46
<PAGE>

however, that if the payment within a reasonable time to the Trustee of the
costs, expenses or liabilities likely to be incurred by it in the making of such
investigation is, in the opinion of the Trustee, not reasonably assured to the
Trustee by the security afforded to it by the terms of this Subordinated
Indenture, the Trustee may require reasonable indemnity against such costs,
expenses or liabilities as a condition to such proceeding; and provided further,
that nothing in this subsection (f) shall require the Trustee to give the
Subordinated Securityholders any notice other than that required by Section
6.10. The reasonable expense of every such examination shall be paid by the
Company or, if paid by the Trustee, shall be reimbursed by the Company upon
demand;

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

     (h)  The Trustee shall be under no responsibility for the approval by it in
good faith of any expert for any of the purposes expressed in this Subordinated
Indenture.

     SECTION 7.03.  Trustee Not Responsible for Recitals or Application of
                    ------------------------------------------------------
Proceeds.  The recitals contained herein and in the Subordinated Securities
--------
(other than the certificate of authentication on the Subordinated Securities)
shall be taken as the statements of the Company, and the Trustee assumes no
responsibility for the correctness of the same.  The Trustee makes no
representations as to the validity or sufficiency of this Subordinated Indenture
or of the Subordinated Securities.  The Trustee shall not be accountable for the
use or application by the Company of any of the Subordinated Securities or of
the proceeds thereof.

     SECTION 7.04.  Trustee May Own Subordinated Securities or Coupons.  The
                    --------------------------------------------------
Trustee, any Paying Agent, registrar or any agent of the Company or of the
Trustee, in its individual or any other capacity, may become the owner or
pledgee of Subordinated Securities or Coupons with the same rights it would have
if it were not Trustee, Paying Agent, registrar or such other agent.

     SECTION 7.05.  Moneys Received by Trustee to be Held in Trust.  Moneys held
                    ----------------------------------------------
by the Trustee in trust need not be segregated from other funds except to the
extent required by law.  The Trustee shall be under no liability for interest on
any money received by it hereunder except as otherwise agreed with the Company.

     SECTION 7.06.  Trustee Entitled to Compensation, Reimbursement and
                    ---------------------------------------------------
Indemnity.  The Company agrees to pay to the Trustee from time to time
---------
reasonable compensation (which shall not be limited by any provision of law in
regard to the compensation of a trustee of any express trust), and the Company
will pay or reimburse the Trustee upon its request for all reasonable expenses,
disbursements and advances incurred or made by the Trustee in connection with
the acceptance or administration of its trust under this Subordinated Indenture
(including the reasonable compensation and the expenses and disbursements of its
counsel and of all Persons not regularly in its employ) except any such expense,
disbursement or advance as may arise from its negligence or bad faith. The
Company also agrees to indemnify the Trustee for, and to hold it harmless
against, any loss, liability or expense incurred without negligence or bad faith
on the

                                       47
<PAGE>

part of the Trustee and arising out of or in connection with the acceptance or
administration of this trust, including the reasonable costs and expenses of
defending itself against any claim of liability in the premises. The obligations
of the Company under this Section to compensate the Trustee, to pay or reimburse
the Trustee for expenses, disbursements and advances and to indemnify and hold
harmless the Trustee shall constitute additional indebtedness hereunder and
shall survive the satisfaction and discharge of this Subordinated Indenture.
Such additional indebtedness shall be secured by a lien prior to that of the
Subordinated Securities upon all property and funds held or collected by the
Trustee as such, except funds held in trust for the payment of principal of or
interest or redemption premium on particular Subordinated Securities.

     SECTION 7.07.  Right of Trustee to Rely on Officer's Certificate Where No
                    ----------------------------------------------------------
Other Evidence Specifically Prescribed.  Except as otherwise provided in Section
--------------------------------------
7.01, whenever in the administration of the provisions of this Subordinated
Indenture the Trustee shall deem it necessary or desirable that a matter be
proved or established prior to taking, suffering or omitting any action
hereunder, such matter (unless other evidence in respect thereof be herein
specifically prescribed) may, in the absence of negligence or bad faith on the
part of the Trustee, be deemed to be conclusively proved and established by an
Officer's Certificate of the Company delivered to the Trustee, and such
Officer's Certificate, in the absence of negligence or bad faith on the part of
the Trustee, shall be full warrant to the Trustee for any action taken, suffered
or omitted by it under the provisions of this Subordinated Indenture upon the
faith thereof.

     SECTION 7.08.  Disqualification; Conflicting Interest.  (a)  If the Trustee
                    --------------------------------------
has or shall acquire any conflicting interest, as defined in this Section 7.08,
it shall, within 90 days after ascertaining that it has such conflicting
interest, and if the Event of Default to which such conflicting interest relates
has not been cured or duly waived or otherwise eliminated before the end of such
90-day period, the Trustee shall either eliminate such conflicting interest or,
except as otherwise provided in this Section 7.08, resign in the manner and with
the effect specified in Section 7.10, such resignation to become effective upon
the appointment of a successor trustee and such successor's acceptance of such
appointment, and the Company shall take prompt steps to appoint a successor in
accordance with Section 7.10.

     (b)  In the event that the Trustee shall fail to comply with the provisions
of subsection (a) of this Section 7.08, the Trustee shall, within ten days after
the expiration of such 90-day period, transmit notice of such failure to the
Subordinated Securityholders in the manner and to the extent provided in
subsection (c) of Section 5.04 with respect to reports pursuant to subsection
(a) of said Section 5.04.

     (c)  Subject to the provisions of Section 6.11 of this Subordinated
Indenture, unless the Trustee's duty to resign is stayed as provided in
subsection (f) of this Section 7.08, any Holder who has been a bona fide Holder
of Subordinated Securities for at least six months may, on such Holder's behalf
and on behalf of all other Holders similarly situated, petition any court of
competent jurisdiction for the removal of such Trustee and the appointment of a
successor, if such Trustee fails after written request thereof by such Holder to
comply with the provisions of subsection (a) of this Section 7.08.

     (d)  For the purposes of this Section 7.08 the Trustee shall be deemed to
have a conflicting interest with respect to the Subordinated Securities of any
series if an Event of

                                       48
<PAGE>

Default (exclusive of any period of grace or requirement of notice) has occurred
with respect to Subordinated Securities of such series and:

          (1) the Trustee is trustee under another indenture under which any
other securities, or certificates of interest or participation in any other
securities, of the Company or any other obligor on the Subordinated Securities
are outstanding or is trustee for more than one outstanding series of
securities, as hereinafter defined, under a single indenture of the Company or
any other obligor on the Subordinated Securities, unless such other indenture is
a collateral trust indenture under which the only collateral consists of
Subordinated Securities issued under this Subordinated Indenture, provided that
there shall be excluded from the operation of this paragraph, this Subordinated
Indenture with respect to the Subordinated Securities of any other series
Outstanding, and any other indenture or indentures under which other securities,
or certificates of interest or participation in other securities, of the Company
or any other obligor on the Subordinated Securities are outstanding, if (A) this
Subordinated Indenture is and such other indenture or indentures (and all series
of securities issued thereunder) are wholly unsecured and rank equally, and such
other indenture or indentures (and such series) are hereafter qualified under
the Trust Indenture Act, unless the Commission shall have found and declared by
order pursuant to subsection (b) of Section 305 or subsection (c) of Section 307
of the Trust Indenture Act, that differences exist between the provisions of
this Subordinated Indenture with respect to Subordinated Securities of such
series and one or more other series, or the provisions of this Subordinated
Indenture and the provisions of such other indenture or indentures (or such
series), which are so likely to involve a material conflict of interest as to
make it necessary in the public interest or for the protection of investors to
disqualify the Trustee from acting as such under this Subordinated Indenture
with respect to Subordinated Securities of such series and such other series, or
under this Subordinated Indenture and such other indenture or indentures, or (B)
the Company shall have sustained the burden of proving, on application to the
Commission and after opportunity for hearing thereon, that the trusteeship under
this Subordinated Indenture with respect to Subordinated Securities of such
series and such other series, or under this Subordinated Indenture and such
other indenture, is not so likely to involve a material conflict of interest as
to make it necessary in the public interest or for the protection of investors
to disqualify the Trustee from acting as such under this Subordinated Indenture
with respect to Subordinated Securities of such series and such other series, or
under this Subordinated Indenture and one of such indentures;

          (2) the Trustee or any of its directors or executive officers is an
underwriter for the Company or any other obligor on the Subordinated Securities;

          (3) the Trustee directly or indirectly controls or is directly or
indirectly controlled by or is under direct or indirect common control with an
underwriter for the Company or any other obligor on the Subordinated Securities;

          (4) the Trustee or any of its directors or executive officers is a
director, officer, partner, employee, appointee or representative of the Company
or any other obligor on the Subordinated Securities, or of an underwriter (other
than the Trustee itself) for the Company or any other obligor on the
Subordinated Securities who is currently engaged in the business of
underwriting, except that (A) one individual may be a director and/or an
executive officer of the Trustee and a director and/or an executive officer of
the Company or any other obligor on the

                                       49
<PAGE>

Subordinated Securities, but may not be at the same time an executive officer of
both the Trustee and the Company or any other obligor on the Subordinated
Securities; (B) if and so long as the number of directors of the Trustee in
office is more than nine, one additional individual may be a director and/or an
executive officer of the Trustee and a director of the Company or any other
obligor on the Subordinated Securities; and (C) the Trustee may be designated by
the Company or any other obligor on the Subordinated Securities or by an
underwriter for the Company or any other obligor on the Subordinated Securities
to act in the capacity of transfer agent, registrar, custodian, paying agent,
fiscal agent, escrow agent or depositary, or in any other similar capacity, or,
subject to the provisions of paragraph (1) of this subsection (d), to act as
trustee whether under an indenture or otherwise;

          (5) ten percent or more of the voting securities of the Trustee is
beneficially owned either by the Company or any other obligor on the
Subordinated Securities or by any director, partner or executive officer
thereof, or 20% or more of such voting securities is beneficially owned,
collectively, by any two or more of such Persons; or ten percent or more of the
voting securities of the Trustee is beneficially owned either by an underwriter
for the Company or any other obligor on the Subordinated Securities or by any
director, partner or executive officer thereof or is beneficially owned,
collectively, by any two or more such Persons;

          (6) the Trustee is the beneficial owner of, or holds as collateral
security for an obligation which is in default, as hereinafter defined, (A) five
percent or more of the voting securities, or ten percent or more of any other
class of security, of the Company or any other obligor on the Subordinated
Securities, not including the Subordinated Securities issued under this
Subordinated Indenture and securities issued under any other indenture under
which the Trustee is also trustee, or (B) ten percent or more of any class of
security of an underwriter for the Company or any other obligor on the
Subordinated Securities;

          (7) the Trustee is the beneficial owner of, or holds as collateral
security for an obligation which is in default, as hereinafter defined, five
percent or more of the voting securities of any Person who, to the knowledge of
the Trustee, owns ten percent or more of the voting securities of, or controls
directly or indirectly or is under direct or indirect common control with the
Company or any other obligor on the Subordinated Securities;

          (8) the Trustee is the beneficial owner of, or holds as collateral
security for an obligation which is in default, as hereinafter defined, ten
percent or more of any class of security of any Person who, to the knowledge of
the Trustee, owns 50% or more of the voting securities of the Company or any
other obligor on the Subordinated Securities;

          (9) the Trustee owns on the date of the occurrence of such Event of
Default (exclusive of any period of grace or requirement of notice) or any
anniversary thereof while such Event of Default remains outstanding, in the
capacity of executor, administrator, testamentary or inter vivos trustee,
guardian, committee or conservator, or in any other similar capacity an
aggregate of 25% or more of the voting securities or of any class of security,
of any Person, the beneficial ownership of a specified percentage of which would
have constituted a conflicting interest under paragraph (6), (7) or (8) of this
subsection (d).  As to any such securities of which the Trustee acquired
ownership through becoming executor, administrator or testamentary trustee of an
estate which included them, the provisions of the preceding sentence shall not

                                       50
<PAGE>

apply, for a period of two years from the date of such acquisition, to the
extent that such securities included in such estate do not exceed 25% of such
voting securities or 25% of any such class of security.  Promptly after the date
of the occurrence of any such Event of Default and annually in each succeeding
year that the Subordinated Securities or any series thereof remain in default,
the Trustee shall make a check of its holdings of such securities in any of the
above-mentioned capacities as of such date.  If the Company or any other obligor
on the Subordinated Securities fails to make payment in full of principal of or
interest on any of the Subordinated Securities when and as the same become due
and payable and such failure continues for 30 days thereafter, the Trustee shall
make a prompt check of its holdings of such securities in any of the above-
mentioned capacities as of the date of the expiration of such 30-day period, and
after such date, notwithstanding the foregoing provisions of this paragraph (9),
all such securities so held by the Trustee, with sole or joint control over such
securities vested in it, shall, but only so long as such failure shall continue,
be considered as though beneficially owned by the Trustee for the purposes of
paragraphs (6), (7) and (8) of this subsection (d); or

          (10) except under the circumstances described in paragraphs (1), (3),
(4), (5) or (6) of Section 7.13(b), the Trustee shall be or become a creditor of
the Company or any other obligor on the Subordinated Securities.

     The specifications of percentages in paragraphs (5) to (9), inclusive, of
this subsection (d) shall not be construed as indicating that the ownership of
such percentages of the securities of a Person is or is not necessary or
sufficient to constitute direct or indirect control for the purposes of
paragraph (3) or (7) of this subsection (d).

     For the purposes of paragraphs (6), (7), (8) and (9) of this subsection (d)
only, (A) the terms "security" and "securities" shall include only such

subscribe to or purchase, any of the foregoing.

          (7)  For the purpose of subsection (d)(1) of this Section 7.08, the

securities issuable under an indenture pursuant to whose terms Holders of one
such series may vote to direct the indenture trustee, or otherwise take action

Section shall be calculated in accordance with the following provisions:

fund relating to securities of the issuer of the same class;

               (ii)   Subordinated Securities of an issuer held in a sinking

by the issuer thereof;

provided, however, that any voting securities of an issuer shall be deemed
outstanding if any Person other than the issuer is entitled to exercise the
voting rights thereof.

          (E)  A security shall be deemed to be of the same class as another
security if both securities confer upon the Holder or Holders thereof
substantially the same rights and privileges, provided, however, that, in the
case of secured evidences of indebtedness, all of which are issued under a
single indenture, differences in the interest rates or maturity dates of various
series thereof shall not be deemed sufficient to constitute such series
different classes, and provided further that, in the case of unsecured evidences
of indebtedness, differences in the interest rate or maturity dates thereof
shall not be deemed sufficient to constitute them securities of different
classes, whether or not they are issued under a single indenture.

     (f)  Except in the case of a default in the payment of the principal of or
interest on any Subordinated Securities, or in the payment of any sinking or
purchase fund installment, the Trustee shall not be required to resign as
provided by this Section 7.08 if the Trustee shall have sustained the burden of
proving, on application to the Commission and after opportunity for hearing
thereon, that (i) the default under this Subordinated Indenture may be cured or
waived during a reasonable period and under the procedures described in such
application, and (ii) a stay of the Trustee's duty to resign will not be
inconsistent with the interests of Holders of such series of Subordinated
Securities.  The filing of such an application shall automatically stay the
performance of the duty to resign until the Commission orders otherwise.  Any
resignation of the Trustee shall become effective only upon the appointment of a
successor trustee and such successor's acceptance of such appointment.

     SECTION 7.09.  Requirements for Eligibility of Trustee.  There shall always
                    ---------------------------------------
be at least one Trustee hereunder.  The Trustee hereunder shall at all times be
a Company organized and doing business as a commercial bank under the laws of
the United States of America or any state thereof or of the District of Columbia
or a Company or other Person permitted to act as a trustee by the Commission
and, in each case, authorized under such laws to exercise corporate trust
powers, having a combined capital and surplus of at least $50,000,000, and
subject to supervision or examination by Federal, State or District of Columbia
authority.  If such Company publishes reports of condition at least annually,
pursuant to law or to the requirements of the aforesaid supervising or examining
authority, then for the purposes of this Section, the combined capital and
surplus of such Company shall be deemed to be its combined capital and surplus
as set forth in its most recent report of condition so published. No obligor on
the Subordinated Securities or Person directly or indirectly controlling,
controlled by or under common control with such obligor shall serve as Trustee.
In case at any time the Trustee shall cease to be eligible in accordance with
the provisions of this Section 7.09, the Trustee shall resign immediately in the
manner and with the effect specified in this Article Seven.

     SECTION 7.10.  Resignation and Removal of Trustee; Appointment of
                    --------------------------------------------------
Successor.  (a)  The Trustee, or any trustee or trustees hereafter appointed,
may at any time resign with respect to one or more or all series of Subordinated
Securities by giving written notice of resignation to the Company and (i) if any
Unregistered Subordinated Securities of a series affected are then Outstanding,
by giving notice of such resignation to the Holders thereof, by publication at
least once in an Authorized Newspaper in the Borough of Manhattan, The City of
New York, and at least once in an Authorized Newspaper in London (and, if
required by Section 4.09, at least once in an Authorized Newspaper in
Luxembourg), (ii) if any Unregistered Subordinated Securities of a series
affected are then Outstanding, by mailing notice of such resignation to the
Holders thereof who have filed their names and addresses with the Trustee
pursuant to Section 313(c)(2) of the Trust Indenture Act at such addresses as
were so furnished to the Trustee and (iii) by mailing notice of such resignation
to the Holders of then Outstanding Registered Securities of each series affected
at their addresses as they shall appear on the registry books. Upon receiving
such notice of resignation, the Company shall promptly appoint a successor
trustee or trustees with respect to the applicable series by written instrument
in duplicate, executed by authority of the Board of Directors, one copy of which
instrument shall be delivered to the resigning Trustee and one copy to the
successor trustee or trustees. If no successor trustee shall have been so
appointed with respect to any series and have accepted appointment within 30
days after the mailing of such notice of resignation, the resigning trustee may
petition any court of competent jurisdiction for the appointment of a successor
trustee, or any Subordinated Securityholder who has been a bona fide Holder of a
Subordinated Security or Subordinated Securities of the applicable series for at
least six months may, subject to the provisions of Section 5.12, on behalf of
himself and all others similarly situated, petition any such court for the
appointment of a successor trustee. Such court may thereupon, after such notice,
if any, as it may deem proper and prescribe, appoint a successor trustee.

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

          (1) the Trustee shall fail to comply with the provisions of subsection
(a) of Section 7.08 after written request therefor by the Company or by any
Subordinated

                                       54
<PAGE>

Securityholder who has been a bona fide Holder of a Subordinated Security or
Subordinated Securities of the applicable series for at least six months; or

          (2) the Trustee shall cease to be eligible in accordance with the
provisions of Section 7.09 and shall fail to resign after written request
therefor by the Company or by any such Subordinated Securityholder; or

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

          (4) the Company shall determine that the Trustee has failed to perform
its obligations under this Subordinated Indenture in any material respect, then,
in any such case, the Company may remove the Trustee and appoint a successor
trustee by written instrument executed by an authorized officer of the Company,
one copy of which instrument shall be delivered to the Trustee so removed and
one copy to the successor trustee, or, subject to the provisions of Section
6.11, any Subordinated Securityholder who has been a bona fide Holder of a
Subordinated Security or Subordinated Securities of the affected series for at
least six months may, on such Person's behalf and on behalf of all others
similarly situated, petition any court of competent jurisdiction for the removal
of the Trustee and the appointment of a successor trustee with respect to such
series.  Such court may thereupon, after such notice, if any, as it may deem
proper and prescribe, remove the Trustee and appoint a successor trustee.

     (c)  The Holders of a majority in principal amount of the Subordinated
Securities Outstanding (determined as provided in Section 8.04) may at any time
remove the Trustee and appoint a successor trustee by written instrument or
instruments signed by such Holders or their attorneys-in-fact duly authorized,
or by the affidavits of the permanent chairman and secretary of a meeting of the
Subordinated Securityholders evidencing the vote upon a resolution or
resolutions submitted thereto with respect to such removal and appointment (as
provided in Article Nine), and by delivery thereof to the Trustee so removed, to
the successor trustee and to the Company.

     (d)  Any resignation or removal of the Trustee and any appointment of a
successor trustee pursuant to any of the provisions of this Section 7.10 shall
become effective upon acceptance of appointment by the successor trustee as
provided in Section 7.11.

     SECTION 7.11.  Acceptance of Appointment by Successor Trustee.  Any
                    ----------------------------------------------
successor trustee appointed as provided in Section 7.10 shall execute,
acknowledge and deliver to the Company and to its predecessor trustee an
instrument accepting such appointment hereunder, and thereupon the resignation
or removal of the predecessor trustee shall become effective and such successor
trustee, without any further act, deed or conveyance, shall become vested with
all the rights, powers, duties and obligations with respect to such series of
its predecessor hereunder, with like effect as if originally named as trustee
herein; but, nevertheless, on the written request of the Company or of the
successor trustee, the trustee ceasing to act shall, upon payment of any amounts
then due it pursuant to the provisions of Section 7.06, execute and deliver an
instrument transferring to such successor trustee all the rights and powers with
respect to the trustee so ceasing to act.  Upon written request of any such
successor trustee, the Company shall execute

                                       55
<PAGE>

any and all instruments in writing for more fully and certainly vesting in and
confirming to such successor trustee all such rights and powers. Any trustee
ceasing to act shall, nevertheless, retain a lien upon all property or funds
held or collected by such trustee to secure any amounts then due it pursuant to
the provisions of Section 7.06.

     No successor trustee shall accept appointment as provided in this Section
7.11 unless at the time of such acceptance such successor trustee shall be
qualified under the provisions of Section 7.08 and eligible under the provisions
of Section 7.09.

     Upon acceptance of appointment by a successor trustee as provided in this
Section 7.11, the Company shall give notice thereof (a) if any Unregistered
Subordinated Securities of a series affected are then Outstanding, to the
Holders thereof, by publication of such notice at least once in an Authorized
Newspaper in the Borough of Manhattan, The City of New York and at least once in
an Authorized Newspaper in London (and, if required by Section 3.09, at least
once in an Authorized Newspaper in Luxembourg), (b) if any Unregistered
Subordinated Securities of a series affected are then Outstanding, to the
Holders thereof who have filed their names and addresses with the Trustee
pursuant to Section 313(c)(2) of the Trust Indenture Act, by mailing such notice
to such Holders at such addresses as were so furnished to the Trustee (and the
Trustee shall make such information available to the Company for such purpose)
and (c) to the Holders of Registered Subordinated Securities of each series
affected, by mailing such notice to such Holders at their addresses as they
shall appear on the registry books.  If the acceptance of appointment is
substantially contemporaneous with the resignation, then the notice called for
by the preceding sentence may be combined with the notice called for by Section
7.10.  If the Company fails to give such notice within ten days after acceptance
of appointment by the successor trustee, the successor trustee shall cause such
notice to be given at the expense of the Company.

     SECTION 7.12.  Successor to Trustee by Merger, Consolidation or Succession
                    -----------------------------------------------------------
to Business.  Any Company into which the Trustee may be merged or converted or
-----------
with which it may be consolidated, or any Company resulting from any merger,
conversion or consolidation to which the Trustee shall be a party, or any
Company succeeding to all or substantially all of the corporate trust business
of the Trustee, shall be the successor of the Trustee hereunder, provided such
Company shall be qualified under the provisions of Section 7.08 and eligible
under the provisions of Section 7.09, without the execution or filing of any
paper or any further act on the part of any of the parties hereto, anything
herein to the contrary notwithstanding.

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

                                       56
<PAGE>

Subordinated Securities in the name of any predecessor Trustee shall apply only
to its successor or successors by merger, conversion or consolidation.

     SECTION 7.13.  Preferential Collection of Claims Against Company.  (a)
                    -------------------------------------------------
Subject to the provisions of subsection (b) of this Section 7.13, if the Trustee
shall be or shall become a creditor, directly or indirectly, secured or
unsecured, of the Company or any other obligor on the Subordinated Securities
within three months prior to a default, as defined in subsection (c) of this
Section 7.13, or subsequent to such a default, then, unless and until such
default shall be cured, the Trustee shall set apart and hold in a special
account for the benefit of the Trustee individually, the Holders of the
Subordinated Securities for which it is acting as Trustee, and the holders of
other indenture securities (as defined in subsection (c) of this Section 7.13):

          (1) an amount equal to any and all reductions in the amount due and
owing upon any claim as such creditor in respect of principal or interest,
effected after the beginning of such three months' period, and valid as against
the Company or such other obligor on the Subordinated Securities and its other
creditors, except any such reduction resulting from the receipt or disposition
of any property described in paragraph (2) of this subsection, or from the
exercise of any right of set-off which the Trustee could have exercised if a
petition in bankruptcy had been filed by or against the Company or such other
obligor on the Subordinated Securities upon the date of such default; and

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

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

          (A) to retain for its own account (i) payments made on account of any
such claim by any Person (other than the Company or such other obligor on the
Subordinated Securities) who is liable thereon, and (ii) the proceeds of the
bona fide sale of any such claim by the Trustee to a third Person, and (iii)
distributions made in cash, securities or other property in respect of claims
filed against the Company or such other obligor on the Subordinated Securities
in bankruptcy or receivership or in proceedings for reorganization pursuant to
Title 11 of the United States Code or applicable State laws;

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

          (C) to realize, for its own account, but only to the extent of the
claim hereinafter mentioned, upon any property held by it as security for any
such claim, if such claim was created after the beginning of such three months'
period and such property was received as security therefor simultaneously with
the creation thereof, and if the Trustee shall sustain the burden of proving
that at the time such property was so received, the Trustee had no reasonable

                                       57
<PAGE>

cause to believe that a default, as defined in subsection (c) of this Section
7.13, would occur within three months; or

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

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

     If the Trustee shall be required to account, the funds and property held in
such special account and the proceeds thereof shall be apportioned among the
Trustee, the Holders of Subordinated Securities for which it is acting as
Trustee, and the holders of other indenture securities in such manner that the
Trustee, such Subordinated Securityholders and the holders of other indenture
securities realize, as a result of payments from such special account and
payments of dividends on claims filed against the Company or such other obligor
on the Subordinated Securities in bankruptcy or receivership or in proceedings
for reorganization pursuant to Title 11 of the United States Code or applicable
State law, the same percentage of their respective claims, figured before
crediting to the claim of the Trustee anything on account of the receipt by it
from the Company or such other obligor on the Subordinated Securities of the
funds and property in such special account and before crediting to the
respective claims of the Trustee, such Subordinated Securityholders, and the
holders of other indenture securities dividends on claims filed against the
Company or such other obligor on the Subordinated Securities in bankruptcy or
receivership or in proceedings for reorganization pursuant to Title 11 of the
United States Code or applicable State law, but after crediting thereon receipts
on account of the indebtedness represented by their respective claims from all
sources other than from such dividends and from the funds and property so held
in such special account.  As used in this paragraph, with respect to any claim,
the term "dividends" shall include any distribution with respect to such claim
in bankruptcy or receivership or in proceedings for reorganization pursuant to
Title 11 of the United States Code or applicable State law, whether such
distribution is made in cash, securities or other property, but shall not
include any such distribution with respect to the secured portion, if any, of
such claim.  The court in which such bankruptcy, receivership or proceeding for
reorganization is pending shall have jurisdiction (i) to apportion among the
Trustee, such Subordinated Securityholders, and the holders of other indenture
securities, in accordance with the provisions of this paragraph, the funds and
property held in such special account and the proceeds thereof, or (ii) in lieu
of such apportionment in whole or in part, to give to the provisions of this
paragraph due consideration in determining the fairness of the distributions to
be made to the Trustee, such Subordinated Securityholders and the holders of
other indenture securities with respect to their respective claims, in which
event it shall not be necessary to liquidate or to appraise the value of any
securities or other property held in such special account or as security for any
such claim, or to make a specific allocation of such distributions as between
the secured and unsecured portions of such claim, or otherwise to apply the
provisions of this paragraph as a mathematical formula.

                                       58
<PAGE>

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

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

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

     In every case commenced under the Bankruptcy Act of 1898, or any amendment
thereto enacted prior to November 6, 1978, all references to periods of three
months shall be deemed to be references to periods of four months.

     (b)  There shall be excluded from the operation of subsection (a) of this
Section 7.13 a creditor relationship arising from:

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

          (2)  advances authorized by a receivership or bankruptcy court of
competent jurisdiction, or by this Subordinated Indenture, for the purpose of
preserving any property which shall at any time be subject to the lien of this
Subordinated Indenture or of discharging tax liens or other prior liens or
encumbrances thereon, if notice of such advance and of the circumstances
surrounding the making thereof is given to the Subordinated Securityholders at
the time and in the manner provided in Section 5.04(c) with respect to reports
pursuant to subsections (a) and (b) thereof, respectively;

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

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

          (5)  the ownership of stock or of other securities of a Company
organized under the provisions of Section 25(a) of the Federal Reserve Act, as
amended, which is directly or indirectly a creditor of the Company or any other
obligor on the Subordinated Securities; and

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

                                       59
<PAGE>

     (c)  As used in this Section 7.13 the following terms shall be accorded the
following definitions:

          (1) the term "default" shall mean any failure to make payment in full
of the principal of or interest on any of the Subordinated Securities or on the
other indenture securities when and as such principal or interest becomes due
and payable.

          (2) the term "other indenture securities" shall mean securities upon
which the Company or any other obligor on the Subordinated Securities is an
"obligor" (as defined in the Trust Indenture Act) outstanding under any other
indenture (A) under which the Trustee is also trustee, (B) which contains
provisions substantially similar to the provisions of subsection (a) of this
Section 7.13, and (C) under which a default exists at the time of the
apportionment of the funds and property held in said special account.

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

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

     SECTION 7.14.  Appointment of Authenticating Agent.  As long as any
                    -----------------------------------
Subordinated Securities of a series remain Outstanding, the Trustee may, by an
instrument in writing, appoint with the approval of the Company an
authenticating agent (the "Authenticating Agent") which shall be authorized to
act on behalf of the Trustee to authenticate Subordinated Securities, including
Subordinated Securities issued upon exchange, registration of transfer, partial
redemption or pursuant to Section 2.09.  Subordinated Securities of each such
series authenticated by such Authenticating Agent shall be entitled to the
benefits of this Subordinated Indenture and shall be valid and obligatory for
all purposes as if authenticated by the Trustee.  Whenever reference is made in
this Subordinated Indenture to the authentication and delivery of Subordinated
Securities of any series by the Trustee or to the Trustee's Certificate of
Authentication, such reference shall be deemed to include authentication and
delivery on behalf of the Trustee by an Authenticating Agent for such series and
a Certificate of Authentication executed on behalf of the Trustee by such
Authenticating Agent.  Such Authenticating Agent shall at all times be a
corporation organized and doing business under the laws of the United States of
America or of any State, authorized under such laws to exercise corporate trust
powers, having a combined capital and surplus of at least $45,000,000
(determined as provided in Section 7.09 with respect to the Trustee) and subject
to supervision or examination by Federal or State authority.

                                       60
<PAGE>

     Any corporation into which any Authenticating Agent may be merged or
converted, or with which it may be consolidated, or any corporation resulting
from any merger, conversion or consolidation to which any Authenticating Agent
shall be a party, or any corporation succeeding to the corporate agency business
of any Authenticating Agent, shall continue to be the authenticating Agent with
respect to all series of Subordinated Securities for which it served as
Authenticating Agent without the execution or filing of any paper or any further
act on the part of the Trustee or such Authenticating Agent.  Any Authenticating
Agent may at any time, and if it shall cease to be eligible shall, resign by
giving written notice of resignation to the Trustee and to the Company.

     Upon receiving such a notice of resignation or upon such a termination, or
in case in any time any Authenticating Agent shall cease to be eligible in
accordance with the provisions of this Section 7.14 with respect to one or more
series of Subordinated Securities, the Trustee shall upon receipt of a Company
Order appoint a successor Authenticating Agent and the Company shall provide
notice of such appointment to all Holders of Subordinated Securities of such
series in the manner and to the extent provided in Section 13.02.  Any successor
Authenticating Agent upon acceptance of its appointment hereunder shall become
vested with all rights, powers, duties and responsibilities of its predecessor
hereunder, with like effect as if originally named as Authenticating Agent.  The
Company agrees to pay to the Authenticating Agent for such series from time to
time reasonable compensation.  The Authenticating Agent for the Subordinated
Securities of any series shall have no responsibility or liability for any
action taken by it as such at the direction of the Trustee.

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

     This is one of the Subordinated Securities described in the within-
mentioned Subordinated Indenture.

     Sections 7.02, 7.03, 7.04, 7.06 and 8.03 shall be applicable to any
Authenticating Agent.

                                 ARTICLE EIGHT

                  CONCERNING THE SUBORDINATED SECURITYHOLDERS

     SECTION 8.01.  Evidence of Action by Subordinated Securityholders. Whenever
                    --------------------------------------------------
in this Subordinated Indenture it is provided that the Holders of a specified
percentage in principal amount of the Subordinated Securities of any or all
series may take any action (including the making of any demand or request, the
giving of any notice, consent or waiver or the taking of any other action), the
fact that at the time of taking any such action the Holders of such specified
percentage have joined therein may be evidenced (a) by any instrument or any
number of instruments of similar tenor executed by such Subordinated
Securityholders in Person or by agent or proxy appointed in writing, or (b) by
the record of such Holders of Subordinated Securities voting in favor thereof at
any meeting of such Subordinated Securityholders duly called and held in
accordance with the provisions of Article Nine, or (c) by a combination of such
instrument or instruments and any such record of such a meeting of such
Subordinated Securityholders.

     SECTION 8.02.  Proof of Execution of Instruments and of Holding of
                    ---------------------------------------------------
Subordinated Securities.  Subject to the provisions of Sections 7.01, 7.02 and
-----------------------
9.05, proof of the execution of any instrument by a Subordinated Securityholder
or such Holder's agent or proxy and proof of the holding by any Person of any of
the Subordinated Securities shall be sufficient if made in the following manner:

     (a) The fact and date of the execution by any such Person of any instrument
may be proved in any reasonable manner acceptable to the Trustee;

     (b) The ownership of Subordinated Securities of any series (including
Registered Global Subordinated Securities) shall be proved by the Register of
such Subordinated Securities of such series, or by certificates of the
Subordinated Security registrar or registrars thereof.

     The Trustee shall not be bound to recognize any Person as a Subordinated
Securityholder unless and until such Person's title to the Subordinated
Securities held by it is proved in the manner in this Article Eight provided.

     The record of any Subordinated Securityholders' meeting shall be proved in
the manner provided in Section 9.06.

     The Trustee may accept such other proof or require such additional proof of
any matter referred to in this Section 8.02 as it shall deem reasonable.

     SECTION 8.03.  Who May be Deemed Owners of Subordinated Securities. Prior
                    ---------------------------------------------------
to due presentment for transfer of any Subordinated Security, the Company, the
Trustee and any agent of the Company or the Trustee may deem and treat the
Person in whose name such Subordinated Security shall be registered upon the
Register of Subordinated Securities of the series of which such Subordinated
Security is a part as the absolute owner of such Subordinated Security (whether
or not such Subordinated Security shall be overdue and notwithstanding any
notation of ownership or other writing thereon) for the purpose of receiving
payment of or on account of the principal of and interest, subject to the
provisions of this Subordinated Indenture, on such

                                       62
<PAGE>

Subordinated Security and for all other purposes; and neither the Company nor
the Trustee nor any agent of the Company or the Trustee shall be affected by any
notice to the contrary. All such payments so made to any such Holder for the
time being, or upon such Holder's order, shall be valid, and, to the extent of
the sum or sums so paid, effectual to satisfy and discharge the liability of
moneys payable upon any such Subordinated Security. The Company, the Trustee and
any agent of the Company or the Trustee may treat the Holder of any Unregistered
Subordinated Security and the Holder of any Coupon as the absolute owner of such
Unregistered Subordinated Security or Coupon (whether or not such Unregistered
Subordinated Security or Coupon shall be overdue) for the purpose of receiving
payment thereof or on account thereof and for all other purposes and neither the
Company, the Trustee, nor any agent of the Company or the Trustee shall be
affected by any notice to the contrary. All such payments so made to any such
person, or upon his order, shall be valid, and, to the extent of the sum or sums
so paid, effectual to satisfy and discharge the liability for moneys payable
upon any such Unregistered Subordinated Security or Coupon.

     If the Subordinated Securities of any series are issued in the form of one
or more Registered Global Subordinated Securities, the Depository therefor may
grant proxies to Persons having a beneficial ownership in such Registered Global
Subordinated Security or Subordinated Securities for purposes of voting or
otherwise responding to any request for consent, waiver or other action which
the Holder of such Registered Subordinated Security is entitled to grant or take
under this Subordinated Indenture and the Trustee shall accept such proxies for
the purposes granted; provided that neither the Trustee nor the Company shall
have any obligation with respect to the grant of or solicitation by the
Depository of such proxies.

     SECTION 8.04.  Subordinated Securities Owned by the Company or Controlled
                    ----------------------------------------------------------
or Controlling Persons Disregarded for Certain Purposes.  In determining whether
-------------------------------------------------------
the Holders of the requisite principal amount of Subordinated Securities have
concurred in any demand, direction, request, notice, vote, consent, waiver or
other action under this Subordinated Indenture, Subordinated Securities which
are owned by the Company or any other obligor on the Subordinated Securities or
by any Person directly or indirectly controlling or controlled by or under
direct or indirect common control with the Company or any other obligor on the
Subordinated Securities shall be disregarded and deemed not to be Outstanding
for the purpose of any such determination, provided that for the purposes of
determining whether the Trustee shall be protected in relying on any such
demand, direction, request, notice, vote, consent, waiver or other action, only
Subordinated Securities which a Responsible Officer of the Trustee assigned to
its principal office knows are so owned shall be so disregarded. Subordinated
Securities so owned which have been pledged in good faith may be regarded as
Outstanding for the purposes of this Section 8.04, if the pledgee shall
establish to the satisfaction of the Trustee the pledgee's right to vote such
Subordinated Securities and that the pledgee is not a Person directly or
indirectly controlling or controlled by or under direct or indirect common
control with the Company or any such other obligor.

     Upon request of the Trustee, the Company shall furnish to the Trustee
promptly an Officer's Certificate listing and identifying all Subordinated
Securities, if any, known by the Company to be owned or held by or for the
account of the Company or any other obligor on the Subordinated Securities or by
any Person directly or indirectly controlling or controlled by or under direct
or indirect common control with the Company or any other obligor on the

                                       63
<PAGE>

Subordinated Securities; and, subject to the provisions of Section 7.01, the
Trustee shall be entitled to accept such Officer's Certificate as conclusive
evidence of the facts therein set forth and of the fact that all Subordinated
Securities not listed therein are Outstanding for the purpose of any such
determination.

     SECTION 8.05.  Instruments Executed by Subordinated Securityholders Bind
                    ---------------------------------------------------------
Future Holders.  At any time prior to (but not after) the evidencing to the
--------------
Trustee, as provided in Section 8.01, of the taking of any action by the Holders
of the percentage in principal amount of the Subordinated Securities specified
in this Subordinated Indenture in connection with such action, any Holder of a
Subordinated Security which is shown by the evidence to be included in the
Subordinated Securities the Holders of which have consented to such action may,
by filing written notice with the Trustee at its principal office and upon proof
of holding as provided in Section 8.02, revoke such action so far as concerns
such Subordinated Security.  Except as aforesaid any such action taken by the
Holder of any Subordinated Security and any direction, demand, request, notice,
waiver, consent, vote or other action of the Holder of any Subordinated Security
which by any provisions of this Subordinated Indenture is required or permitted
to be given shall be conclusive and binding upon such Holder and upon all future
Holders and owners of such Subordinated Security, and of any Subordinated
Security issued in lieu thereof, irrespective of whether any notation in regard
thereto is made upon such Subordinated Security.  Any action taken by the
Holders of the percentage in principal amount of the Subordinated Securities of
any or all series specified in this Subordinated Indenture in connection with
such action shall be conclusively binding upon the Company, the Trustee and the
Holders of all of the Subordinated Securities of such series subject, however,
to the provisions of Section 7.01.

Subordinated Securityholders, setting forth the time and place of such meeting
and in general terms the action proposed to be taken at such meeting, shall be
mailed not less than 20 nor more than 60 days prior to the date fixed for the

     SECTION 9.03.  Call of Meeting by the Company or Subordinated

Securityholders.  In case at any time the Company pursuant to a resolution of
---------------
its Board of Directors, or the Holders of not less than ten percent in principal
amount of the Subordinated Securities of any or all series, as the case may be,
then Outstanding, shall have requested the Trustee to call a meeting of Holders
of Subordinated Securities of any or all series, as the case may be, to take any
action authorized in Section 9.01 by written request setting forth in reasonable
detail the action proposed to be taken at the meeting, and the Trustee shall not

then the Company or such Holders of Subordinated Securities in the amount above

Francisco, California or The City of New York, New York for such meeting and may
call such meeting to take any action authorized in Section 9.01, by mailing (and
publishing, if required) notice thereof as provided in Section 9.02.

     SECTION 9.04.  Who May Attend and Vote at Meetings.  To be entitled to vote
                    -----------------------------------

---------------------------
Subordinated Indenture, the Trustee may make such reasonable regulations as it
may deem advisable for any meeting of Subordinated Securityholders, in regard to
proof of the holding of Subordinated Securities and of the appointment of
proxies, and in regard to the appointment and duties of inspectors of votes, the
submission and examination of proxies, certificates and other evidence of the
right to vote, and such other matters concerning the conduct of the meeting as
it shall think fit.  Except as otherwise permitted or required by any such
regulations, the holding of Subordinated Securities shall be proved in the
manner specified in Section 8.02. and the appointment of any proxy shall be
proved in the manner specified in said Section 8.02; provided, however, that
such regulations may provide that written instruments appointing proxies regular
on their face, may be presumed valid and genuine without the proof hereinabove
or in said Section 8.02 specified.

     The Trustee shall by an instrument in writing, appoint a temporary chairman
of the meeting, unless the meeting shall have been called by the Company or by
Subordinated

                                       65
<PAGE>

Securityholders as provided in Section 9.03, in which case the Company or the
Subordinated Securityholders calling the meeting, as the case may be, shall in

secretary of the meeting shall be elected by majority vote of the meeting.

     Subject to the provisions of Section 8.04, at any meeting each Subordinated
Securityholder or proxy shall be entitled to one vote for each $1,000 (or [Euro]
1,000) principal amount (in the case of Original Issue Discount Subordinated

Subordinated Securities held or represented by such Holder; provided, however,
that no vote shall be cast or counted at any meeting in respect of any
Subordinated Security challenged as not Outstanding and ruled by the chairman of
the meeting to be not Outstanding.  The chairman of the meeting shall have no
right to vote other than by virtue of Subordinated Securities held by such
Person or instruments in writing as aforesaid duly designating such Person as
the Person to vote on behalf of other Subordinated Securityholders.  Any meeting
of Subordinated Securityholders duly called pursuant to the provisions of
Section 9.02 or 9.03 may be adjourned from time to time, and the meeting may be
held so adjourned without further notice.

     At any meeting of Subordinated Securityholders, the presence of Persons
holding or representing Subordinated Securities in principal amount sufficient
to take action on the business for the transaction of which such meeting was
called shall constitute a quorum, but, if less than a quorum is present, the
Persons holding or representing a majority in principal amount of the
Subordinated Securities represented at the meeting may adjourn such meeting with
the same effect for all intents and purposes, as though a quorum had been
present.

     SECTION 9.06.  Manner of Voting at Meetings and Record to be Kept. The vote

any resolution and who shall make and file with the secretary of the meeting
their verified written reports in duplicate of all votes cast at the meeting.  A
record in duplicate of the proceedings of each meeting of Subordinated
Securityholders shall be prepared by the secretary of the meeting and there
shall be attached to said record the original reports of the inspectors of votes
on any vote by ballot taken thereat and affidavits by one or more Persons having
knowledge of the facts setting forth a copy of the notice of the meeting and
showing that said notice was mailed as provided in Section 9.02.  The record
shall show the principal amount or principal amounts of the Subordinated
Securities voting in favor of or against any resolution.  The record shall be
signed and verified by the affidavits of the permanent chairman and secretary of
the meeting and one copy thereof shall be delivered to the Company and the other
to the Trustee to be preserved by the Trustee.

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

---------------------------------------------
contained shall be deemed or construed to authorize or permit, by reason of any
call of a meeting of Subordinated Securityholders or any rights expressly or

     (c) to add to the covenants of the Company such further covenants,
restrictions or conditions as its Board of Directors and the Trustee shall

Securities, stating that such covenants, restrictions or conditions are
expressly being included solely for the benefit of such series), and to make the
occurrence, or the occurrence and continuance, of a default in any such
additional covenants, restrictions or conditions an Event of Default permitting
the enforcement of all or any of the several remedies provided in this
Subordinated Indenture as herein set forth; provided, however, that in respect
to any such additional covenant, restriction or condition such Supplemental
Subordinated Indenture may provide for a particular period of grace after
default (which period may be shorter or longer than that allowed in the case of
other defaults) or may provide for an immediate enforcement upon such default or
may limit the remedies available to the Trustee upon such default;

<PAGE>

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

     (f)  to establish the form or terms of Subordinated Securities of any
series or the Coupons appertaining to such Subordinated Securities as permitted

provisions of this Subordinated Indenture and to add to or change the provisions
of this Subordinated Indenture to such extent as shall be necessary to
facilitate the performance of the duties of such trustee; and

     (h)  to cure any ambiguity or to correct or supplement any provisions
contained herein or in any Supplemental Subordinated Indenture which may be
defective or inconsistent with any other provision contained herein or in any
Supplemental Subordinated Indenture, or to make such other provisions in regard
to matters or questions arising under this Subordinated Indenture or any
Supplemental Subordinated Indenture which shall not adversely affect the
interests of the Holders of the Subordinated Securities or Coupons.

     SECTION 10.02.  Modification of Subordinated Indenture With Consent of
                     ------------------------------------------------------

Section 8.01) of the Holders of not less than a majority in principal amount of
the Subordinated Securities of all series at the time Outstanding (determined as
provided in Section 8.04) affected by such Supplemental Subordinated Indenture
(voting as one class), the Company and the Trustee may from time to time and at
any time enter into an indenture or indentures supplemental hereto (which shall
comply with the provisions of the Trust Indenture Act as then in effect) for the
purpose of adding any provisions to or changing in any manner or eliminating any
of the provisions of this Subordinated Indenture or of any Supplemental
Subordinated Indenture or of modifying in any manner the rights of the Holders
of the Subordinated Securities of each such series or the Coupons appertaining
to such Subordinated Securities; provided, however, that no such Supplemental
Subordinated Indenture shall, without the consent of the Holders of each
Outstanding Subordinated Security affect thereby:

     (a)  change the Stated Maturity of the principal of, or any installment of
principal of or interest on, any Subordinated Security, or reduce the principal
amount thereof or the rate of interest thereon or any premium payable upon the
redemption thereof, or reduce the amount of the principal of an Original Issue
Discount Subordinated Security or any other Subordinated Security which would be
due and payable upon a declaration of acceleration of the Stated Maturity
thereof pursuant to Section 6.01, or change any place of payment where, or the
coin or currency in which, any Subordinated Security or any premium or interest
thereon is payable, or impair the right to institute suit for the enforcement of
any such payment on or after the Stated Maturity thereof (or, in the case of
redemption, on or after the date fixed for redemption), or modify the provisions
of this Subordinated Indenture with respect to this subordination of the
Subordinated Securities in a manner adverse to the Holders, or

<PAGE>

     (b)  Reduce the percentage in principal amount of the Outstanding
Subordinated Securities the consent of the Holders of which is required for any
such Supplemental Subordinated Indenture, or the consent of the Holders of which
is required for any waiver (of compliance with certain provisions of this
Subordinated Indenture or certain defaults hereunder and their consequences)
provided for in this Subordinated Indenture or

     (c)  Change the time of payment or reduce the amount of any minimum sinking
account or fund payment or

     (d)  Modify any of the provisions of this Section 10.02, except to increase
any such percentage or to provide that certain other provisions of this
Subordinated Indenture cannot be modified or waived without the consent of the
Holder of each Subordinated Security affected thereby.

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

     Upon the request of the Company, accompanied by a copy of a resolution of
the Board of Directors (which resolution may provide general terms or parameters
for such action and may provide that the specific terms of such action may be
determined in accordance with or pursuant to a Company Order) certified by the
secretary or an assistant secretary of the Company authorizing the execution of
any such supplemental indenture, and upon the filing with the Trustee of
evidence of the consent of the Holders of the Subordinated Securities as
aforesaid and other documents, if any, required by Section 8.01, the Trustee
shall join with the Company in the execution of such supplemental indenture
unless such supplemental indenture affects the Trustee's own rights, duties or
immunities under this Subordinated Indenture or otherwise, in which case the
Trustee may in its discretion, but shall not be obligated to, enter into such
supplemental indenture.

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

     Promptly after the execution by the Company and the Trustee of any
supplemental indenture pursuant to the provisions to this Section, the Trustee
shall give notice thereof (i) to the Holders of then Outstanding Registered
Subordinated Securities of each series affected thereby, by mailing a notice
thereof by first-class mail to such Holders at their addresses as they shall
appear on the Security Register, (ii) if any Unregistered Subordinated
Securities of a series affected thereby are then Outstanding, to the Holders
thereof who have filed their names and addresses with the Trustee pursuant to
Section 313(c)(2) of the Trust Indenture Act, by mailing a notice thereof by
first-class mail to such Holders at such addresses as were so furnished to the
Trustee and (iii) if any Unregistered Subordinated Securities of a series
affected thereby are then

                                       69

Outstanding, to all Holders thereof, by publication of a notice thereof at least
once in an Authorized Newspaper in the Borough of Manhattan, The City of New
York and at least once in an Authorized Newspaper in London (and, if required by
Section 4.09, at least once in an Authorized Newspaper in Luxembourg), and in
each case such notice shall set forth in general terms the substance of such
supplemental indenture. Any failure of the Company to give such notice, or any
defect therein, shall not, however, in any way impair or affect the validity of
any such supplemental indenture.

     SECTION 10.03.  Effect of Supplemental Subordinated Indentures.  Upon the
                     ----------------------------------------------
execution of any Supplemental Subordinated Indenture pursuant to the provisions
of this Article Ten, this Subordinated Indenture shall be and be deemed to be
modified and amended in accordance therewith and the respective rights,
limitations of rights, obligations, duties and immunities under this
Subordinated Indenture of the Trustee, the Company and the Holders of
Subordinated Securities shall thereafter be determined, exercised and enforced
hereunder subject in all respects to such modifications and amendments, and all
the terms and conditions of any such Supplemental Subordinated Indenture shall
be and be deemed to be part of the terms and conditions of this Subordinated
Indenture for any and all purposes.

     The Trustee shall be entitled to receive, and subject to the provisions of
Section 7.01 shall be entitled to rely upon, an Opinion of Counsel as conclusive
evidence that any such Supplemental Subordinated Indenture complies with the
provisions of this Article Ten and that the Subordinated Securities affected by
the Supplemental Subordinated Indenture, when such Subordinated Securities are
authenticated and delivered by the Trustee and executed and issued by the
Company in the manner and subject to any conditions specified in such Opinion of
Counsel, will be valid and binding obligations of the Company, except as any
rights thereunder may be limited by bankruptcy, insolvency and other similar
laws affecting the enforcement of creditors' rights generally and by general
equity principles.

     SECTION 10.04.  Subordinated Securities May Bear Notation of Changes by
                     -------------------------------------------------------
Supplemental Subordinated Indentures.  Subordinated Securities authenticated and

delivered after the execution of any Supplemental Subordinated Indenture
pursuant to the provisions of this Article Ten, or after any action taken at a
Subordinated Securityholders' meeting pursuant to Article Nine, may bear a
notation in form approved by the Trustee as to any matter provided for in such
Supplemental Subordinated Indenture or as to any action taken at any such
meeting.  If the Company or the Trustee shall so determine, new Subordinated
Securities so modified as to conform, in the opinion of the Trustee and the
Company, to any modification of this Subordinated Indenture contained in any
such Supplemental Subordinated Indenture may be prepared by the Company,
authenticated by the Trustee and delivered in exchange for the Subordinated
Securities then Outstanding.

     Subordinated Securities of such series and Coupons appertaining thereto
     will not recognize income, gain or loss for United States Federal income
     tax purposes as a result of such deposit, defeasance and discharge and will
     be subject to United States Federal income tax on the same amount and in
     the same manner and at the same times, as would have been the case if such
     deposit, defeasance and discharge had not occurred; and

          (d)  the Company has delivered to the Trustee an Officer's Certificate
     and an Opinion of Counsel, each stating that all conditions precedent
     provided for relating to the defeasance contemplated by this provision have

Subordinated Securities, and any Coupons appertaining thereto, outstanding on
and after the date the conditions set forth below are satisfied (hereinafter,
"covenant defeasance").  For this purpose, such covenant defeasance means that,
with respect to the Outstanding Subordinated Securities of any series, the
Company may omit to comply with and shall have no liability in respect of any
term, condition or limitation set forth in such Section, whether directly or
indirectly by reason of any reference elsewhere herein to such Section or by
reason of any reference in such Section to any other provision herein or in any
other document and such omission to comply shall not constitute an Event of
Default under Section 6.01, but the remainder of this Subordinated Indenture and
such Subordinated Securities and Coupons shall be unaffected thereby.  The
following shall be the conditions to application of this subsection C of this
Section 11.01:

     are due and payable in accordance with the terms of the Subordinated
     Indenture and the Subordinated Securities of such series;

     or both would become an Event of Default with respect to the Subordinated
     Securities shall have occurred and be continuing on the date of such

     conflicting interest as defined in Section 7.08 and for purposes of the
     Trust Indenture Act with respect to any securities of the Company;

          (d)  Such covenant defeasance shall not result in a breach or

     will not recognize income, gain or loss for United States Federal income
     tax purposes as a result of such covenant defeasance and will be subject to
     United States Federal income tax on the same amounts, in the same manner
     and at the same times as would have been the case if such covenant
     defeasance had not occurred; and

          (g)  The Company shall have delivered to the Trustee an Officer's
     Certificate and an Opinion of Counsel, each stating that all conditions
     precedent provided for relating to the covenant defeasance contemplated by

the construction hereof.

     SECTION 13.08.  Subordinated Securities in a Foreign Currency or in ECU.
                     -------------------------------------------------------
Unless otherwise specified in an Officer's Certificate delivered pursuant to
Section 2.03 of this Subordinated Indenture with respect to a particular series
of Subordinated Securities, whenever for purposes of this Subordinated Indenture
any action may be taken by the Holders of a specified percentage in aggregate
principal amount of Subordinated Securities of all series or all series affected
by a particular action at the time Outstanding and, at such time, there are
Outstanding Subordinated Securities of any series which are denominated in a
coin or currency other than United States Dollars (including ECUs), then the
principal amount of Subordinated Securities of such series which shall be deemed
to be Outstanding for the purpose of taking such action shall be that amount of
United States Dollars that could be obtained for such amount at the Market
Exchange Rate.  For purposes of this Section 13.08, Market Exchange Rate shall
mean the noon United States Dollar buying rate in The City of New York for cable
transfers of that

                                       78

currency as published by the Federal Reserve Bank of New York; provided, in the
case of ECUs, Market Exchange Rate shall mean the rate of exchange determined by
the Commission of the European Communities (or any successor thereto) as
published in the Official Journal of the European Communities (such publication
or any successor publication, the "Journal"). If such Market Exchange Rate is
not available for any reason with respect to such currency, the Trustee shall
use, in its sole discretion and without liability on its part, such quotation of
the Federal Reserve Bank of New York or, in the case of ECUs, the rate of
exchange as published in the Journal, as of the most recent available date, or
quotations or, in the case of ECUs, rates of exchange from one or more major
banks in The City of New York or in the country of issue of the currency in
question, which for purposes of the ECU shall be Brussels, Belgium, or such
other quotations or, in the case of ECU, rates of exchange as the Trustee shall
deem appropriate. The provisions of this paragraph shall apply in determining
the equivalent principal amount in respect of Subordinated Securities of a
series denominated in a currency other than Dollars in connection with any
action taken by Holders of Subordinated Securities pursuant to the terms of this
Subordinated Indenture.

     All decisions and determinations of the Trustee regarding the Market
Exchange Rate or any alternative determination provided for in the preceding
paragraph shall be in its sole discretion and shall, in the absence of manifest
error, be conclusive to the extent permitted by law for all purposes and
irrevocably binding upon the Company and all Holders.

     SECTION 13.09.  Judgment Currency.  The Company agrees, to the fullest
                     -----------------
extent that it may effectively do so under applicable law, that (a) if for the
purpose of obtaining judgment in any court it is necessary to convert the sum
due in respect of the principal of or interest on the Subordinated Securities of
any series (the "Required Currency"), into a currency in which a judgment will
be rendered (the "Judgment Currency"), the rate of exchange used shall be the
rate at which in accordance with normal banking procedures the Trustee could
purchase in The City of New York the Required Currency with the Judgment
Currency on the day on which final unappealable judgment is entered, unless such
day is not a New York Banking Day, then, to the extent permitted by applicable
law, the rate of exchange used shall be the rate at which in accordance with
normal banking procedures the Trustee could purchase in The City of New York the
Required Currency with the Judgment Currency on the New York Banking Day
preceding the day on which final unappealable judgment is entered and (b) its
obligations under this Subordinated Indenture to make payments in the Required
Currency (i) shall not be discharged or satisfied by any tender, or any recovery
pursuant to any judgment (whether or not entered in accordance with subsection
(a)), in any currency other than the Required Currency, except to the extent
that such tender or recovery shall result in the actual receipt, by the payee,
of the full amount of the Required Currency expressed to be payable in respect
of such payments, (ii) shall be enforceable as an alternative or additional
cause of action for the purpose of recovering in the Required Currency the
amount, if any, by which such actual receipt shall fall short of the full amount
of the Required Currency so expressed to be payable and (iii) shall not be
affected by judgment being obtained for any other sum due under this
Subordinated Indenture.  For purposes of the foregoing, "New York Banking Day"
means any day except a Saturday, Sunday or a legal holiday in The City of New
York or a day on which banking institutions in The City of New York are
authorized or required by law or executive order to close.

                     -----------------------------------------------------
