on the campus of California State University, Fresno (hereinafter the
"Premises") for research, educational, and related purposes and uses in
conformity with Title V of the California Code of Regulations Section 42500,
in the furtherance of California State University, Fresno's (hereinafter the
"University") educational mission; and

WHEREAS, BION is involved in the business of developing innovative livestock
nutrient management systems; and

WHEREAS, BION wishes to contribute certain equipment/structures to the
Agricultural Foundation for mutually-beneficial research purposes (as such
purposes are described in Exhibit C hereto), and install the same on the
Premises, subject to the terms and conditions contained herein; and

WHEREAS, from time to time, the California Agricultural Technology Institute
(hereinafter "CATI") may serve as the designee of the Agricultural Foundation
for the purposes of conducting agriculturally related research projects
utilizing the property/facilities leased by the Agricultural Foundation; and

WHEREAS, it is the desire of the Agricultural Foundation, through its
designee, CATI, to engage in such agriculturally related research and
educational activities on the terms and conditions contained herein.

NOW THEREFORE, in consideration of the mutual recitals and promises herein
contained and for such other and further consideration as is hereby
acknowledged, and upon consultation with their respective counsel/advisors
and/or opportunity therefor, the parties agree as follows:

1.     Term and Termination.  (a) This Agreement shall be effective upon the
due execution of the Construction Agreement (as defined below).  Once
effective, this Agreement shall continue in full force and effect for a period
of thirty (30) days following the Completion Date (as defined in section 6(a)
below) (hereinafter the "Term"), subject to earlier termination in accordance
with the provisions hereof.

(b)     BION shall have the right to terminate this Agreement, effective
immediately upon written notice, if (i) the University Parties (as defined
below) fail to substantially perform their duties pursuant hereto or (ii) the
University Parties breach the provisions hereof.

(c)      The Agricultural Foundation shall have the right to terminate this
Agreement effective immediately upon written notice if BION fails to
substantially perform its duties pursuant hereto or it breaches the provisions
hereof.

2.     Equipment.  BION agrees that it will provide to the Agricultural
Foundation, at no cost to the Agricultural Foundation, the University, the
Trustees of the California State University, CATI, or the State of California,
such equipment and the related structure as specified in Exhibit A attached
hereto and incorporated herein by this reference (collectively, the
"Equipment").  The Agricultural Foundation shall allow the Equipment to be
installed on the Premises by May 1, 2003 or as soon thereafter as reasonably
possible.  Notwithstanding the foregoing, the parties understand and agree
that the Agricultural Foundation shall be responsible for (i) its portion of
the taxes set forth in Section 4(a), with BION being responsible for its own
portion of said taxes pursuant thereto, (ii) the laboratory research and other
costs set forth in Section 6(a), and (iii) all ongoing operational and
maintenance costs related to the Transferred Equipment (as defined below)
incurred following the Term.

3.     Installation of Equipment.  BION will cause the Equipment to be
installed on that portion of the Premises identified to and approved by the
Executive Director of the Agricultural Foundation, by retaining a California
general contractor experienced and qualified to perform the installation of
the Equipment (hereinafter the "Contractor").  The Contractor will be selected
by BION, but will be subject to the reasonable approval of the Agricultural
Foundation.  BION will be solely responsible for all installation,
installation materials and related fees, costs and expenses, and will
indemnify, defend and hold harmless the Agricultural Association, the Trustees
of the California State University, California State University, Fresno, CATI,
the State of California (together, the "University Parties"), and each of said
entities' employees, agents, representatives, divisions, directors, officers,
and attorneys (hereinafter, an "Agent") from and against such installation,
installation materials and related fees, costs and expenses (including, but
not limited to, the cost of the Equipment, the Contractor's fees and costs,
and all other related costs and expenses), as well as all liability, suits,
claims and damages arising from or relating to such installation.  In
conformity with this paragraph 3, the Agricultural Foundation, the Contractor
and BION will enter into a separate written agreement in compliance with the

California State University, CATI, and California State University, Fresno,
which written agreement shall detail the rights and responsibilities of the
parties thereto, as it applies to the Equipment installation goods and
services to be provided by the Contractor, in a form to be mutually agreed
upon by the party (the "Construction Agreement").

4.     Title to Equipment; License to use Equipment and Technology.  (a) Title
to such of the Equipment (the "Transferred Equipment") that is listed on
Exhibit A but that is not listed on Exhibit B shall pass to the Agricultural
Foundation upon delivery of the Equipment to Premises, provided however, that
should the Agricultural Foundation substantially fail to perform its duties or
obligations hereunder, or otherwise materially breach this Agreement, (i) as a
result of conditions that are not beyond the control of the Agricultural
Foundation, and (ii) at a time when BION is not in material breach of this

Agreement that resulted in the University Parties' above-referenced failure to
perform or breach, then title to the Transferred Equipment shall be conveyed
back to BION, and the University Parties agree to timely execute any documents
and take any actions reasonably requested by BION to accomplish such
conveyance.  With respect to those items listed on Exhibit B (the "Bion
Equipment"), BION shall at all times retain title thereto.  BION will be
solely responsible for the removal of the Bion Equipment from the Premises
following the Completion Date and all costs attendant thereto.  Any and all
taxes payable in connection with the transfer of title to the Transferred
Equipment shall be borne such that BION will pay one-half of such taxes, and
the remaining one-half shall be paid by the Agricultural Foundation.

(b) BION hereby grants to the Agricultural Foundation and CATI, as designee of
the Agricultural Foundation, (i) a royalty-free license, which may not be
assigned or sublicensed, to use the Equipment solely to conduct the Research
at the Premises, pursuant to the protocol set forth on Exhibit C hereto and
the other terms and conditions hereof during the Term, and (ii) a
non-exclusive, royalty-free license, which may not be assigned or sublicensed,
to use the Know-How (as defined below) solely at the Premises and pursuant to
the protocol set forth on Exhibit C hereto and the other terms and conditions
hereof, (x) to operate the BION Equipment during the Term, and (y) to operate
the Transferred Equipment during the Term and for purposes of the Fresno
Research for a period of 20 years commencing upon the end of the Term.
"Know-How" shall mean all technical data, information, drawings and designs,
know-how, trade secrets, procedures, protocols, software object and source
code, algorithms and instructions constituting part of or used in connection
with the Bion System (as defined below) that is in the possession of the
Licensor, to the extent that same is required for the use of the Bion System
at the Premises pursuant to the terms of this Agreement.  In the event that
the Agricultural Foundation or CATI, as its designee, materially fails to
comply with the operating conditions set forth on Exhibit C hereto, and such
failure results in damage to the Bion System or interferes with the effective
operation of the Bion System, then BION shall have the right to immediately
terminate the licenses granted pursuant to this Section 4(b).

5.     Damage to Property.  (a) At no time during the Term will BION commit
any act, or fail to perform any act, that damages the Premises or other
property of the University Parties.  Following the Completion Date and during
the Term, BION will be responsible for the removal of the Bion Equipment from
the Premises, and for the return of the Premises to such condition as existed
prior to the execution of this Agreement, normal wear and tear excepted.
Notwithstanding the foregoing, BION will promptly replace the master research
control panel (which it will remove and retain following the Completion Date)
with an operational control panel capable of properly controlling and
monitoring the Transferred Equipment.  In this regard, BION agrees that
immediately following its execution of this Agreement, it will place on
deposit in a trust account with the California State University, Fresno
Foundation ("Foundation"), the sum of Twenty Thousand Dollars ($20,000.00)
(hereinafter the "Deposit") to be held by the Foundation during the Term, as a
security deposit to guarantee BION's faithful compliance with this Section
5(a). The Agricultural Foundation and BION shall both be required to execute
any documents necessary for disbursements to be made from said trust account.
Should BION, or anyone hired by and/or acting on behalf of BION, at any time
during the Term damage the Premises or other property of the University
Parties, the Agricultural Foundation shall notify BION in writing of the type
and amount of such claim, including any supporting documents, and indicate
that it is the intention of the Agricultural Foundation, on behalf of such
damaged entity, to satisfy such claim, in whole or in part, through the
appropriation of all or a portion of the Deposit.   If the Agricultural

Foundation does not receive written notification in accordance with Section 10
hereof of BION's objection to the claim within thirty (30) calendar days
following BION's receipt of the claim, BION will be deemed to have consented
to settlement of the claim out of the Deposit, and BION will thereafter
execute any documents as may be necessary to disburse such funds out of the
Deposit to satisfy the claim.  If BION does send the Agricultural Foundation
notice that it objects to the claim within such thirty-day period, then the
dispute shall be settled by arbitration pursuant to Section 9 hereof.  BION's
obligations referred to in this Section 5(a) shall not be limited to the
amount of the Deposit.  Any Deposit monies remaining at the end of the Term
shall be returned to BION within ten (10) calendar days after the end of the
Term.

(b)     The Agricultural Foundation agrees that to the extent reasonably
practicable, it shall ensure that, at no time during the Term will any
University Party commit any act, or fail to perform any act, that damages the
Equipment, unreasonably interferes with the operation of the Equipment, or
otherwise compromises the integrity of the Bion System Research and/or Bion
System Results (as such terms are defined below).

6.     Research; Results; Ownership.  (a) The Agricultural Foundation shall,
and/or shall cause CATI, as designee of the Agricultural Foundation, to,
utilize the Equipment on the Premises for the purpose of conducting
independent, scientifically-based evaluations of the BION Nutrient Management
Waste Treatment System (as further defined in Exhibit D hereto, the "Bion
System") under the conditions described as "Core Conditions" in Exhibit C
hereto, in order to determine the Bion System's efficacy in reducing potential
pollutants released into the air, surface waters or groundwater from dairy
effluents (the "Phase One Research").  In addition, the Agricultural
Foundation and CATI, as designee, shall provide unrestricted access to the
Premises to such persons as BION shall designate in order to enable BION to
monitor the operations of the Bion System, perform maintenance, conduct
evaluations of the Bion System (including under the conditions described as
"Stress Conditions" in Exhibit C hereto (the "Phase Two Research" and,
together with the Phase One Research, the "Bion System Research")) and for all
other purposes contemplated by this Agreement.  The Agricultural Foundation
and CATI, as its designee, may also conduct research the focus of which is not
the Bion Technology (the "Fresno Research" and, together with the Bion System
Research, the "Research").  The Phase One Research shall be conducted in
accordance with the protocol and within the time periods set forth in Exhibit
C hereto.  The Agricultural Foundation and CATI, as its designee, shall not
commence the Phase One Research until BION advises them in writing that the
Bion System has reached equilibrium.  Copies of any and all raw data, analyses
and lab results resulting from or relating to the Research or any other
analyses of the BION System, or collected from the Bion System by any of the
University Parties, their contracted researchers, and/or any other Agents
thereof (the "Data"), shall be submitted to BION immediately.  The parties
agree that the Agricultural Foundation or CATI, as its designee, shall
complete the Phase One Research and deliver to BION a final written report
thereon (the "Phase One Report"), which shall set forth in detail the findings
of the Phase One Research, within a period of sixty (60) days from the date on
which the Phase One Research is completed in accordance with Exhibit C hereto.
The date on which BION has received the Phase One Report shall hereinafter be
referred to as the "Completion Date."  BION shall have the right to approve or
disapprove of the Phase One Report for any reason whatsoever.  If BION
approves of the Phase One Report, it shall deliver a written notice so
indicating to the Agricultural Foundation.  Failure of BION to notify the
Agricultural Foundation or CATI of BION's approval or disapproval of the Phase
One Report within fourteen (14) calendar days following the Completion Date
shall be deemed to be an approval of the Phase One Report.  Upon the actual or
deemed approval of BION in accordance with this Subsection, the Agricultural
Foundation and/or CATI shall have the right to publish the Phase One report
pursuant to this Section 6.  In the event that BION disapproves of the Phase
One Report by so notifying the Agricultural Foundation or CATI within the
14-day period described above, BION shall have the right to append comments to
the Phase One Report, which shall in all cases be published or disseminated
with the Phase One Report.  BION shall provide such comments to the
Agricultural Foundation or CATI within thirty (30) days following the
Completion Date.  In the event that the Agricultural Foundation and/or CATI,
to their knowledge, substantially fails to adhere to the protocol relative to
the Phase One Research set forth on Exhibit C hereto, then the Agricultural
Foundation and/or CATI shall (i) promptly disclose such failure to BION and
(ii) include in their portion of the Phase One Report a clear statement that,
and the manner in which, such protocol materially was not followed.  The
laboratory costs and all other costs of the Phase One Research and any Fresno
Research, and delivery of the Phase One Report and any other Data to BION,
shall be borne by the Agricultural Foundation.  The laboratory costs and all
other costs of the Phase Two Research shall be borne by BION.

(b) BION shall own all rights, title and interest in and to the results of the
Bion System Research and the Data related thereto, including the Phase One
Report, and any interim reports (collectively, the "Bion System Results").
The Agricultural Foundation shall own all rights, title and interest in and to
the Fresno Research.  However, the University Parties shall have a
non-exclusive right to publish and otherwise disseminate the Phase One Report,
provided that (i) such Phase One Report is delivered to BION at least fourteen
(14) days prior to its dissemination and (ii) if BION disapproves of the
report pursuant to Subsection 6(a) above, then BION shall be permitted to
append comments and/or require the Agricultural Foundation and/or CATI to
include a statement in the Phase One Report in accordance with the provisions
of Subsection 6(a) above.  The University Parties will, at any time at BION's
request and at BION's cost, execute and deliver to BION such assignments,
certificates or other instruments as BION may from time to time deem necessary
or desirable to evidence, establish, maintain, perfect, protect, enforce or
defend BION's right, title and interest in and to the Bion System Results.

(c) The Bion Equipment, the Bion System, the Know-How and any and all
Improvements (defined below) (collectively, the "Bion Technology") are and
shall remain the sole and exclusive property of BION.  For purposes hereof,
"Improvements" shall mean any version, enhancement, modification or refinement
of the Bion System, the Know-How and/or technologies related to biological

            CITIGROUP INC., a Delaware corporation (the "Company", which term
includes any successor Person under the Indenture), for value received, hereby
promises to pay to Cede & Co., or registered assigns, the principal sum of
$__________ on February 22, 2033 and to pay interest thereon from and including
February 19, 2003 or from the most recent Interest Payment Date to which
interest has been paid or duly provided for, semi-annually, on February 22 and
August 22 of each year, commencing August 22, 2003, at the rate of 5.875% per
annum, until the principal hereof is paid or made available for payment. The
interest so payable, and punctually paid or duly provided for, on any Interest
Payment Date will, as provided in the Indenture, be paid to the Person in whose
name this Subordinated Note is registered at the close of business on the Record
Date for such interest, which shall be the February 15 and August 15 (whether or
not a Business Day) immediately preceding such Interest Payment Date.
<PAGE>
            Any such interest not so punctually paid or duly provided for will
forthwith cease to be payable to the holder on such Record Date and may either
be paid to the Person in whose name this Subordinated Note is registered at the
close of business on a subsequent Record Date, such subsequent Record Date to be
not less than five days prior to the date of payment of such defaulted interest,
notice whereof shall be given to holders of Subordinated Notes of this series
not less than 15 days prior to such subsequent Record Date, or be paid at any
time in any other lawful manner not inconsistent with the requirements of any
securities exchange on which the Subordinated Notes of this series may be
listed, and upon such notice as may be required by such exchange, all as more
fully provided in the Indenture.

            Interest hereon will be calculated on the basis of a 360-day year
comprised of twelve 30-day months.

            If either an Interest Payment Date or the Maturity of the
Subordinated Notes falls on a day that is not a Business Day, such Interest
Payment Date or Maturity will be the next succeeding Business Day. If a date for
payment of interest or principal on the Subordinated Notes falls on a day that
is not a business day in the place of payment, such payment will be made on the
next succeeding business day in such place of payment as if made on the date the
payment was due. No interest will accrue on any amounts payable for the period
from and after the due date for payment of such principal or interest.

            For these purposes, "Business Day" means any day which is a day on
which commercial banks settle payments and are open for general business in The
City of New York.

            Payment of the principal of and interest on this Subordinated Note
will be made at the office or agency of the Trustee maintained for that purpose
in The City of New York.

            Reference is hereby made to the further provisions of this
Subordinated Note set forth on the reverse hereof, which further provisions
shall for all purposes have the same effect as if set forth at this place.

            Unless the certificate of authentication hereon has been executed by
the Trustee or by an authenticating agent on behalf of the Trustee by manual
signature, this Subordinated Note shall not be entitled to any benefit under the
Indenture or be valid or obligatory for any purpose.

            This Subordinated Note is one of a duly authorized issue of
Securities of the Company (the "Subordinated Notes"), issued and to be issued in
one or more series under the Indenture, dated as of April 12, 2001 (the
"Indenture"), between the Company and Bank One Trust Company, N.A., as Trustee
(the "Trustee", which term includes any successor trustee under the Indenture),
to which Indenture and all indentures supplemental thereto reference is hereby
made for a statement of the respective rights, limitations of rights, duties and
immunities thereunder of the Company, the Trustee and the holders of the
Subordinated Notes and of the terms upon which the Subordinated Notes are, and
are to be, authenticated and delivered. This Subordinated Note is one of the
series designated on the face hereof, initially limited in aggregate principal
to $1,000,000,000.

            The Company covenants and agrees that the indebtedness evidenced by
the Subordinated Notes is subordinate and junior in right of payment to all
Senior Indebtedness (as defined in the Indenture) to the extent provided in the
Indenture, and each holder of Subordinated Notes, by his or her acceptance
thereof, likewise covenants and agrees to the subordination provided in the
Indenture (including Article Fourteen thereof) and shall be bound by the
provisions thereof.

            In the event that the Company shall default in the payment of any
principal of (or premium, if any) or interest on any Senior Indebtedness when
the same becomes due and payable after any applicable grace period, whether at
maturity or at a date fixed for prepayment or by declaration or otherwise, then,
unless and until such default shall have been cured or waived or shall have
ceased to exist, no direct or indirect payment (in cash, property, securities,
by set-off or otherwise) shall be made or agreed to be made on account of the
principal of, or premium, if any, or interest on the indebtedness evidenced by
the Subordinated Notes, or in respect of any redemption, retirement or other
acquisition of any of the Subordinated Notes, except that holders of
Subordinated Notes may receive and retain (x) securities of the Company or any
other corporation provided for by a plan of reorganization or readjustment the
payment of which is subordinate, at least to the extent provided in these
subordination provisions with respect to the indebtedness evidenced by the
Subordinated Notes, to the payment of all Senior Indebtedness at the time
outstanding and to any securities issued in respect thereof under any such plan
of reorganization or readjustment and (y) payments made from a defeasance trust
created pursuant to Article Eleven of the Indenture.

            In the event of:

                  (i) any insolvency, bankruptcy, receivership, liquidation,
      reorganization, readjustment, composition or other similar proceeding
      relating to the Company, its creditors or its property,

                  (ii) any proceeding for liquidation, dissolution or other
      winding up of the Company, voluntary or involuntary, whether or not
      involving insolvency or bankruptcy proceedings,

                                       5
<PAGE>
                  (iii) any assignment by the Company for the benefit of
      creditors, or

                  (iv) any other marshalling of the assets of the Company,

all Senior Indebtedness (including any interest thereon accruing after the
commencement of any such proceedings) shall first be paid in full before any
payment or distribution, whether in cash, securities or other property, shall be
made to any Holder of any of the Subordinated Notes on account thereof (except
as provided in the next sentence). Any payment or distribution, whether in cash,
securities or other property (other than (x) securities of the Company or any
other corporation provided for by a plan of reorganization or readjustment the
payment of which is subordinate, at least to the extent provided in these
subordination provisions with respect to the indebtedness evidenced by the
Subordinated Notes, to the payment of all Senior Indebtedness at the time
outstanding and to any securities issued in respect thereof under any such plan
of reorganization or readjustment and (y) payments made from a defeasance trust
created pursuant to Article Eleven of the Indenture), which would otherwise (but
for these subordination provisions) be payable or deliverable in respect of the
Subordinated Notes shall be paid or delivered directly to the holders of Senior
Indebtedness in accordance with the priorities then existing among such holders
until all Senior Indebtedness (including any interest thereon accruing after the
commencement of any such proceedings) shall have been paid in full.

      If an event of default (as defined in the Indenture) with respect to
Subordinated Notes of this series shall occur and be continuing, the principal
of the Subordinated Notes of this series may be declared due and payable in the
manner and with the effect provided in the Indenture.

      The Indenture contains provisions for defeasance at any time of the entire
indebtedness of this Subordinated Note upon compliance by the Company with
certain conditions set forth in Article Eleven thereof, which provisions apply
to this Subordinated Note.

            The Indenture contains provisions permitting the Company and the
Trustee, without the consent of the holders of Securities, to establish, among
other things, the form and terms of any series of Securities issuable thereunder
by one or more supplemental indentures, and, with the consent of the holders of
not less than a majority of the principal amount of Securities at the time
Outstanding which are affected thereby, to modify the Indenture or any
supplemental indenture or the rights of the holders of Securities of such series
to be affected, provided that no such modification shall, without the consent of
the holder of each Outstanding Security so affected, (x) change the Stated
Maturity of the principal of, or any installment of principal of or interest on,
any Security, or reduce the principal amount thereof or the rate of interest
thereon or any premium thereon, or change any place of payment where, or the
coin or currency in which any 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 Redemption Date) or modify the provisions of the Indenture with
respect to the subordination of the Securities in a manner adverse to the
Securityholders or (y) reduce the aforesaid percentage in principal amount of
the Outstanding Securities of any series, the consent of the holders of which is
required for any supplemental indenture, or the consent of whose holders is
required for any waiver provided for in the

                                       6
<PAGE>
Indenture, or (z) modify certain other provisions of the Indenture, as set forth
in Section 13.02 of the Indenture.

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

            This Subordinated Note is a Global Security registered in the name
of a nominee of the Depository. This Subordinated Note is exchangeable for
Subordinated Notes registered in the name of a person other than the Depository
or its nominee only in the limited circumstances hereinafter described. Unless
and until it is exchanged in whole or in part for definitive Subordinated Notes
in certificated form, this Subordinated Note 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.

            The Subordinated Notes represented by this Global Security are
exchangeable for definitive Subordinated Notes in certificated form of like
tenor as such Subordinated Notes in denominations of $1,000 and integral
multiples thereof only if (i) the Depository notifies the Company that it is
unwilling or unable to continue as Depository for the Subordinated Notes or (ii)
the Depository ceases to be a clearing agency registered under the Securities
Exchange Act of 1934, as amended, or (iii) the Company in its sole discretion
decides to allow the Subordinated Notes to be exchanged for definitive
Subordinated Notes in registered form. Any Subordinated Notes that are
exchangeable pursuant to the preceding sentence are exchangeable for
certificated Subordinated Notes issuable in authorized denominations and
registered in such names as the Depository shall direct. As provided in the
Indenture and subject to certain limitations therein set forth, the transfer of
definitive Subordinated Notes in certificated form is registrable in the
register maintained by the Company in The City of New York for such purpose,
upon surrender of the definitive Subordinated Note for registration of transfer
at the office or agency of the registrar, duly endorsed by, or accompanied by a
written instrument of transfer in form satisfactory to the Company and the
registrar duly executed by, the holder thereof or his attorney duly authorized
in writing, and thereupon one or more new Subordinated Notes of this series and
of like tenor, of authorized denominations and for the same aggregate principal
amount, will be issued to the designated transferee or transferees. Subject to
the foregoing, this Subordinated Note is not exchangeable, except for a Global
Security or Global Securities of this issue of the same principal amount to be
registered in the name of the Depository or its nominee.

            No service charge shall be made for any such registration of
transfer or exchange, but the Company may require payment of a sum sufficient to
cover any tax or other governmental charge payable in connection therewith.

            Prior to due presentment of this Subordinated Note for registration
of transfer, the Company, the Trustee and any agent of the Company or the
Trustee may treat the Person in whose name this Subordinated Note is registered
as the owner hereof for all purposes, whether or

                                       7
<PAGE>
not this Subordinated Note be overdue, and neither the Company, the Trustee nor
any such agent shall be affected by notice to the contrary.

      The Company will pay additional amounts ("Additional Amounts") to the
beneficial owner of any Subordinated Note that is a non-United States person in
order to ensure that every net payment on such Subordinated Note will not be
less, due to payment of U.S. withholding tax, than the amount then due and
payable. For this purpose, a "net payment" on a Subordinated Note means a
payment by the Company or a paying agent, including payment of principal and
interest, after deduction for any present or future tax, assessment or other
governmental charge of the United States. These Additional Amounts will
constitute additional interest on the Subordinated Note.

      The Company will not be required to pay Additional Amounts, however, in
any of the circumstances described in items (1) through (13) below.

      (1)   Additional Amounts will not be payable if a payment on a
            Subordinated Note is reduced as a result of any tax, assessment or
            other governmental charge that is imposed or withheld solely by
            reason of the beneficial owner:

            (a)   having a relationship with the United States as a citizen,
                  resident or otherwise;

            (b)   having had such a relationship in the past or

            (c)   being considered as having had such a relationship.

      (2)   Additional Amounts will not be payable if a payment on a
            Subordinated Note is reduced as a result of any tax, assessment or
            other governmental charge that is imposed or withheld solely by
            reason of the beneficial owner:

            (a)   being treated as present in or engaged in a trade or business
                  in the United States;

            (b)   being treated as having been present in or engaged in a trade
                  or business in the United States in the past or

            (c)   having or having had a permanent establishment in the United
                  States.

      (3)   Additional Amounts will not be payable if a payment on a
            Subordinated Note is reduced as a result of any tax, assessment or
            other governmental charge that is imposed or withheld solely by
            reason of the beneficial owner being or having been, any of the
            following (as these terms are defined in the Internal Revenue Code
            of 1986, as amended):

            (a)   personal holding company;

            (b)   foreign personal holding company;

            (c)   foreign private foundation or other foreign tax-exempt
                  organization;

            (d)   passive foreign investment company;

            (e)   controlled foreign corporation or

                                       8
<PAGE>
            (f)   corporation which has accumulated earnings to avoid United
                  States federal income tax.

      (4)   Additional Amounts will not be payable if a payment on a
            Subordinated Note is reduced as a result of any tax, assessment or
            other governmental charge that is imposed or withheld solely by
            reason of the beneficial owner owning or having owned, actually or
            constructively, 10 percent or more of the total combined voting
            power of all classes of stock of the Company entitled to vote or by
            reason of the beneficial owner being a a bank that has invested in a
            Subordinated Note as an extension of credit in the ordinary course
            of its trade or business.

For purposes of items (1) through (4) above, "beneficial owner" means a
fiduciary, settlor, beneficiary, member or shareholder of the holder if the
holder is an estate, trust, partnership, limited liability company, corporation
or other entity, or a person holding a power over an estate or trust
administered by a fiduciary holder.

      (5)   Additional Amounts will not be payable to any beneficial owner of a
            Subordinated Note that is a:

            (a)   fiduciary;

            (b)   partnership;

            (c)   limited liability company or

            (d)   other fiscally transparent entity

            or that is not the sole beneficial owner of the Subordinated Note,
            or any portion of the Subordinated Note. However, this exception to
            the obligation to pay Additional Amounts will only apply to the
            extent that a beneficiary or settlor in relation to the fiduciary,
            or a beneficial owner or member of the partnership, limited
            liability company or other fiscally transparent entity, would not
            have been entitled to the payment of an Additional Amount had the
            beneficiary, settlor, beneficial owner or member received directly
            its beneficial or distributive share of the payment.

      (6)   Additional Amounts will not be payable if a payment on a
            Subordinated Note is reduced as a result of any tax, assessment or
            other governmental charge that is imposed or withheld solely by
            reason of the failure of the beneficial owner or any other person to
            comply with applicable certification, identification, documentation
            or other information reporting requirements. This exception to the
            obligation to pay Additional Amounts will only apply if compliance
            with such reporting requirements is required by statute or
            regulation of the United States or by an applicable income tax
            treaty to which the United States is a party as a precondition to
            exemption from such tax, assessment or other governmental charge.

      (7)   Additional Amounts will not be payable if a payment on a
            Subordinated Note is reduced as a result of any tax, assessment or
            other governmental charge that is

                                       9
<PAGE>
            collected or imposed by any method other than by withholding from a
            payment on a Subordinated Note by the Company or a paying agent.

      (8)   Additional Amounts will not be payable if a payment on a
            Subordinated Note is reduced as a result of any tax, assessment or
            other governmental charge that is imposed or withheld by reason of a
            change in law, regulation, or administrative or judicial
            interpretation that becomes effective more than 15 days after the
            payment becomes due or is duly provided for, whichever occurs later.

      (9)   Additional Amounts will not be payable if a payment on a
            Subordinated Note is reduced as a result of any tax, assessment or
            other governmental charge that is imposed or withheld by reason of
            the presentation by the beneficial owner of a Subordinated Note for
            payment more than 30 days after the date on which such payment
            becomes due or is duly provided for, whichever occurs later.

      (10)  Additional Amounts will not be payable if a payment on a
            Subordinated Note is reduced as a result of any:

            (c)   gift tax;

            (d)   sales tax;

            (e)   excise tax;

            (f)   transfer tax;

            (g)   wealth tax;

            (h)   personal property tax or

            (i)   any similar tax, assessment or other governmental charge.

      (11)  Additional Amounts will not be payable if a payment on a
            Subordinated Note is reduced as a result of any tax, assessment, or
            other governmental charge required to be withheld by any paying
            agent from a payment of principal or interest on a Subordinated Note
            if such payment can be made without such withholding by any other
            paying agent.

      (12)  Additional amounts will not be payable if a payment on a
            Subordinated Note is reduced as a result of any tax, assessment or
            other governmental charge that is required to be made pursuant to
            any European Union directive on the taxation of savings income or
            any law implementing or complying with, or introduced to conform to,
            any such directive.

      (13)  Additional Amounts will not be payable if a payment on a
            Subordinated Note is reduced as a result of any combination of items
            (1) through (12) above.

                                       10

      Except as specifically provided herein, the Company will not be required
to make any payment of any tax, assessment or other governmental charge imposed
by any government or a political subdivision or taxing authority of such
government.

      Except as provided below, the Subordinated Notes may not be redeemed prior
to maturity.

      (1)   The Company may, at its option, redeem the Subordinated Notes if:

            (a)   the Company becomes or will become obligated to pay Additional
                  Amounts as described above;

            (b)   the obligation to pay Additional Amounts arises as a result of
                  any change in the laws, regulations or rulings of the United
                  States, or an official position regarding the application or
                  interpretation of such laws, regulations or rulings, which
                  change is announced or becomes effective on or after February
                  11, 2003 and

            (c)   the Company determines, in its business judgment, that the
                  obligation to pay such Additional Amounts cannot be avoided by
                  the use of reasonable measures available to it, other than
                  substituting the obligor under the Subordinated Notes or
                  taking any action that would entail a material cost to the
                  Company.

      (2)   The Company may also redeem the Subordinated Notes, at its option,
            if:

            (a)   any act is taken by a taxing authority of the United States on
                  or after February 11, 2003, whether or not such act is taken
                  in relation to the Company or any affiliate, that results in a
                  substantial probability that the Company will or may be
                  required to pay Additional Amounts as described above;

            (b)   the Company determines, in its business judgment, that the
                  obligation to pay such Additional Amounts cannot be avoided by
                  the use of reasonable

                                       11

                  measures available to it, other than substituting the obligor
                  under the Subordinated Notes or taking any action that would
                  entail a material cost to the Company and

            (c)   the Company receives an opinion of independent counsel to the
                  effect that an act taken by a taxing authority of the United
                  States results in a substantial probability that the Company
                  will or may be required to pay the Additional Amounts
                  described above, and delivers to the Trustee a certificate,
                  signed by a duly authorized officer, stating that based on
                  such opinion the Company is entitled to redeem the
                  Subordinated Notes pursuant to their terms.

Any redemption of the Subordinated Notes as set forth in clauses (1) or (2)
above shall be in whole, and not in part, and will be made at a redemption price
equal to 100% of the principal amount of the Subordinated Notes Outstanding plus
accrued interest thereon to the date of redemption. Holders shall be given not
less than 30 days nor more than 60 days prior notice by the Trustee of the date
fixed for such redemption.

      All terms used in this Subordinated Note which are defined in the
Indenture shall have the meanings assigned to them in the Indenture. The
Subordinated Notes are governed by the laws of the State of New York.
