Agreement, the Bank shall become and be designated as, automatically and without

Securityholder. Without execution of this Agreement, upon the payment to the
Company for the Company Preferred Securities being acquired by a Person in
connection with the issuance of the Company Preferred Securities on the Closing
Date pursuant to the terms of the related Underwriting Agreement, which action
shall be deemed to constitute a request by such Person that the books and

and shall be bound by all the terms and conditions hereof and of the Company
Preferred Securities.

            Section 2.3 Name. The name of the Company being formed hereby is
"UBS Preferred Funding Company LLC IX". The Company will maintain "UBS" as part
of its name for as long as any Trust Preferred Securities remain outstanding
unless, because of a merger or other business combination involving the Bank or
a change by the Bank of its own name, inclusion of "UBS" as part of the

business of the Company may be conducted upon compliance with all applicable
laws under any other name designated by the Board of Directors.

legal entity shall continue until the cancellation of the Certificate of
Formation in the manner required by the Delaware Act.

offices of the Company shall be determined by the Board of Directors. The Board
of Directors may change the location of the Company's principal place of
business; provided, however, that such change has no material adverse effect
upon any Preferred Securityholder.

            Section 2.7 Qualification in Other Jurisdictions. The Board of
Directors shall cause the Company to be qualified or registered under assumed or
fictitious name statutes or similar laws in any jurisdiction in which the
Company conducts business and in which such qualification or registration is
required by law or deemed advisable by the Board of Directors. Each Person
designated by the Board of Directors as an "authorized person" is authorized to
execute, deliver and file on behalf of the Company any certificates (and any
amendments or restatements thereof) necessary for the Company to qualify to do
business in each jurisdiction in which the Board of Directors has determined

tax purposes. The Company may not conduct any other business or operations
except as contemplated by the preceding sentence. The Company shall have the
power and authority to take any and all actions necessary, appropriate, proper,
advisable, incidental or convenient to or for the furtherance of the purposes of
the Company as set forth herein.

of the Company, with respect to each Person who purchases a Company Preferred
Security on such Closing Date, an amount in cash equal to the Purchase Price for
such Company Preferred Security (such amount being such Person's capital
contribution to the Company). Preferred Securityholders, in their capacity as
Securityholders of the Company, shall not be required to make any additional
contributions to the Company (except as may be required by law).

            Section 4.4 Allocation of Profits and Losses. Except as otherwise
provided in Section 7.3, the profits and losses of the Company for any Financial
Year (or portion thereof) shall be allocated as follows:

                  (a) all gains and losses resulting from any disposition
         (including, without limitation, any redemption or prepayment) of assets
         by the Company shall be allocated 100% to the Common Securityholders;

                  (b) except as otherwise provided in a Certificate of
         Designations, net profit of the Company (determined without regard to
         the amount of any gains and losses described in subparagraph (a) of
         this Section 4.4) shall be allocated (i) pro rata among the Preferred
         Securityholders until the amount so allocated equals the amount of
         dividends paid during such Financial Year (or portion thereof), as
         determined on a when-paid basis with respect to the Company Preferred
         Securities or Company Parity Preferred Securities held by such
         Preferred Securityholder, as adjusted pursuant to Sections 7.3 and 4.3
         or in any Certificate of Designations after the delivery of a No
         Dividend Instruction, and (ii) thereafter to the Common
         Securityholders; and

                  (c) expenses, deductions and net loss of the Company
         (determined without regard to the amount of any gains and losses
         described in subparagraph (a) of this Section 4.4) shall be allocated
         100% to the Common Securityholders.

Notwithstanding the foregoing, the Tax Matters Partner shall have the power to
alter any such allocations for federal, state, and local income tax purposes if
such alteration is necessary to

                                      -15-
<PAGE>
cause such allocations to have "substantial economic effect" (within the meaning
of Treasury regulation section 1.704-1(b)(2)) or to ensure that such allocations
are otherwise in accordance with the interests of the Securityholders (within
the meaning of Treasury regulation section 1.704-1(b)(3)) determined on the
basis of the economic arrangements of the parties as described in this
Agreement.

            Section 4.5 Withholding. The Company shall comply with any
withholding requirements under U.S. federal, state and local and foreign law and
shall remit amounts withheld to and file required forms with applicable
jurisdictions. Subject to the provisions of Section 7.3 to the extent that the
Company is required to withhold and pay over any amounts to any authority with
respect to distributions or allocations to any Securityholder, the amount
withheld shall be deemed to be a distribution in the amount of the withholding
to such Securityholder. The Company will, however, be required to pay additional
amounts so that the net amount received by a Preferred Securityholder after
withholding will not be less than the Mandatory Dividend Payment Amount then due
and payable as described in Section 7.3(c). To the fullest extent permitted by
law, in the event of any claimed over-withholding, Securityholders shall be
limited to an action against the applicable jurisdiction. If the amount required
to be withheld from a distribution was not withheld from such distribution, the
Company may reduce subsequent distributions by the amount of such withholding to
the extent the Company was not required to pay Additional Amounts with respect
to such withholding. Each Securityholder, by its acceptance of Securities, shall
be deemed to agree to furnish the Company with any representations and forms as
shall reasonably be requested by the Company to assist it in determining the
extent of, and in fulfilling, its withholding obligations.

            Section 4.6 Securities as Personal Property. Each Securityholder
hereby agrees that its Company Securities shall for all purposes be personal
property. A Securityholder has no interest in specific property of the Company.

have the power to exercise any and all rights or powers granted to the
Securityholders pursuant to the express terms of this Agreement and of the
By-Laws and shall be subject in all respects to the provisions hereof and
thereof.

that it may have to maintain an action for partition of the property of the
Company.

            Section 5.3 Resignation. A Securityholder may resign from the
Company prior to the dissolution and winding up of the Company only upon the
assignment of its entire ownership interest in any Company Securities (including
by any redemption, repurchase or other acquisition by the Company of such
Company Securities) in accordance with the provisions of this Agreement. A
resigning Securityholder shall not be entitled to receive any distribution and
shall not otherwise be entitled to receive the fair value of its Company
Securities except as otherwise expressly provided for in this Agreement.

liability in excess of (i) the amount of its capital contributions, (ii) its

otherwise, on the Board of Directors occurring before the first annual meeting

initial Officers, and their offices, are set forth in Annex E hereto. Each such

Securityholders of the Company, shall not be agents of the Company and shall not

Director, Officer, Securityholder or Affiliate thereof shall have the right to

considering any proposed action or inaction with respect to the Subordinated
Notes pursuant to Section 6.1(d), take into account the interest of both the
Preferred Securityholders and the Bank, as owner of the Company Common
Securities. To the fullest extent permitted by law, no member of the Board of
Directors shall have any liability to any Preferred Securityholder or the
Company for not voting to take any enforcement action under the Subordinated
Notes in the event of a default by the Cayman Islands Branch in performing any
of its obligations (including payment obligations) thereunder.

            Section 6.8 Additional Directors. If at any time the aggregate of
unpaid Definitive Dividends on the Company Preferred Securities or any Company
Parity Preferred Securities equals or exceeds an amount equal to three
semi-annual dividend payments, the holders of Company Preferred Securities and
any Company Parity Preferred Securities, voting together as a single class, will
have the exclusive right to elect two additional directors. Holders of a
majority of Company Preferred Securities and Company Parity Preferred Securities
may exercise this right by written consent or at a meeting of such holders
called for such purpose. This meeting may be called at the request of any holder
of Company Preferred Securities or Company Parity Preferred Securities. This
right will continue either until all unpaid Definitive Dividends have been paid
in full or until full dividends have been paid on the Company Preferred
Securities for two consecutive dividend periods. While this right continues, any
vacancy in the office of the additional directors may be filled only by the
holders of Company Preferred Securities and Company Parity Preferred Securities
voting as described above.

                     COMPANY SECURITIES; SUBORDINATED NOTES

            Section 7.1       Company Common Securities.

            (a) The Bank, as the initial Common Securityholder, shall be deemed
to have been issued [2,000] Company Common Securities upon its designation as
the Common Securityholder pursuant to Section 2.2 of this Agreement. Upon
issuance as provided in this Agreement, the Company Common Securities so issued
shall be deemed duly authorized, validly issued, fully paid and nonassessable.

            (b) Company Common Securities shall not be evidenced by any
certificate or other written instrument, but shall only be evidenced by this
Agreement.

            (c) The Common Securityholders will receive dividends out of
interest payments received by the Company on the Subordinated Notes and other
Eligible Investments, if any, not required to be applied to fund dividends with
respect to the Company Preferred Securities or expenses of the Company. However,
as long as the Company Preferred Securities or the Company Parity Preferred
Securities are outstanding, no dividends or other distributions (including
redemptions and purchases) may be made with respect to Company Common

                                      -23-
<PAGE>
Securities unless full dividends on all Company Preferred Securities and Company
Parity Preferred Securities have been paid as provided in Section 7.3.

            (d) Subject to the rights, if any, of the Preferred Securityholders
(to the limited extent provided in Section 8.1), all voting rights are vested in
the Company Common Securities. The Common Securityholders are entitled to vote
in proportion to the stated amounts represented by their Company Common
Securities.

            (e) If the Company dissolves, liquidates or winds up (whether
voluntarily or involuntary) after all debts and liabilities of the Company have
been satisfied and there have been paid or set aside for the Preferred
Securityholders the full preferential amounts to which such holders are
entitled, the Common Securityholders will be entitled to share equally and
ratably in any assets remaining.

            Section 7.2 General Provisions Regarding Company Preferred
Securities and Company Parity Preferred Securities.

            (a) There is hereby authorized for issuance and sale Company
Preferred Securities having an aggregate initial liquidation preference of $o.
The specific designation, dividend rate, liquidation preference, redemption
terms, voting rights, exchange limitations and other powers, preferences and
special rights and limitations of the Company Preferred Securities are set forth
in Section 7.3 hereof. Upon issuance as provided in this Agreement, the Company
Preferred Securities and the Company Parity Preferred Securities (if any) so
issued, shall be deemed duly authorized, validly issued, fully paid and
nonassessable.

            The Company has the power to create and issue additional preferred
limited liability company interests in the Company that are junior to the
Company Preferred Securities as to payment of dividends and payments of amounts
upon dissolution, liquidation or winding up of the Company ("Company Junior
Securities") or that are on a parity with the Company Preferred Securities as to
payment of dividends and payments of amounts upon dissolution, liquidation or
winding up of the Company ("Company Parity Preferred Securities") and admit the
purchasers of such limited liability company interests to the Company as members
of the Company. So long as any Company Preferred Securities remain outstanding,
additional Company Parity Preferred Securities may be issued only with the
consent of the holders of two-thirds (based on the aggregate liquidation
preference) of the Company Preferred Securities and Company Parity Preferred
Securities, voting together as a single class, and only if the Bank Subordinated
Guarantee is amended so that such Company Parity Preferred Securities benefit
from the Bank Subordinated Guarantee in the same manner as the Company Preferred
Securities without any adverse effect on holders of the Company Preferred
Securities. See Section 7.3(h).

            The Company may not, without the consent of each Preferred
Securityholder, authorize, create or increase the authorized amount of, or issue
any class or series of equity securities of or limited liability company
interests in the Company, or any warrants, options or other rights convertible
or exchangeable into any class or series of any equity securities of or limited
liability company interests in the Company, ranking prior to the Company
Preferred Securities, either as to dividend rights or rights on dissolution,
winding up or termination of the Company.

                                      -24-
<PAGE>
            Subject to the express provisions of this Agreement and of the
By-Laws, the Board of Directors shall have authority to fix the terms of Company
Parity Preferred Securities that may be issued by the Company by adopting in
accordance with the provisions of this Agreement a Certificate of Designations
relating to such Company Parity Preferred Securities that shall set forth the
preferences and other terms of such series, including without limitation the
following: (1) the title and stated value of such series; (2) the number or
amount by aggregate liquidation preference of securities of such series offered
and the initial liquidation preference per security or minimum denomination of
such series; (3) the dividend rate(s), period(s), and/or payment date(s) or
method(s) of calculation thereof applicable to such series; (4) whether such
Company Parity Preferred Securities are cumulative or not and, if cumulative,
the date from which dividends on such Company Parity Preferred Securities shall
accumulate; (5) the provisions for a sinking fund, if any, for such series; (6)
the provisions for redemption, if applicable, of such series; (7) any voting
rights of such series; (8) the relative ranking and preferences of such series
as to dividend rights and rights upon liquidation, dissolution or winding up of
the affairs of the Company; (9) any limitations on issuance of any Company
Parity Preferred Securities ranking senior to or on a parity with such series of
Company Preferred Securities as to dividend rights and rights upon liquidation,
dissolution or winding up of the affairs of the Company; (10) whether such
Company Parity Preferred Securities will be eligible for issuance as book-entry
Company Parity Preferred Securities; and (11) any other specific terms,
preferences, rights, limitations or restrictions of such series. Upon such
adoption by the Board of Directors, each such Certificate of Designations shall
thereupon be incorporated into and deemed to be part of this Agreement.

            (b) All Company Preferred Securities and Company Parity Preferred
Securities shall rank senior to all Company Junior Securities in respect of the
right to receive dividends or other distributions and the right to receive
payments out of the assets of the Company upon voluntary or involuntary
dissolution, winding-up or termination of the Company in accordance with the
provisions hereof (subject to the provisions of Section 7.3 or any Certificate
of Designations). All Company Preferred Securities and Company Parity Preferred
Securities redeemed, purchased or otherwise acquired by the Company shall be
canceled. The Company Preferred Securities and Company Parity Preferred
Securities shall be issued in registered form only.

            (c) Neither the Bank, the Company nor any of their respective
Affiliates shall have the right to vote or give or withhold consent with respect
to any Company Preferred Security or Company Parity Preferred Security owned by
it, directly or indirectly, and, for purposes of any matter upon which the
Preferred Securityholders may vote or give or withhold consent as provided in
this Agreement, Company Preferred Securities and Company Parity Preferred
Securities owned by any of the Bank, the Company or any of their respective
Affiliates shall be treated as if they were not outstanding.

            (d)   Anything in this Agreement to the contrary notwithstanding:

                  (i) as long as any Company Preferred Securities are
         outstanding, no Company Parity Preferred Securities may be redeemed or
         repurchased unless the Company concurrently redeems an approximately
         equal proportion of the aggregate liquidation preference of the
         outstanding Company Preferred Securities or each Rating

                                      -25-
<PAGE>
         Agency then rating the Company Preferred Securities informs the Company
         in writing that the redemption or repurchase of such Company Parity
         Preferred Securities would not result in a reduction or withdrawal of
         the rating then assigned by that Rating Agency to the Company Preferred
         Securities, and

                  (ii) as long as any Company Preferred Securities or Company
         Parity Preferred Securities remain outstanding, the Company may issue
         or authorize the issuance of any Company Preferred Securities or
         Company Parity Preferred Securities only with the approval of the
         holders of two-thirds (based on the aggregate liquidation preference)
         of the Company Preferred Securities and Company Parity Preferred
         Securities, voting together as a single class, and only if the Bank
         Subordinated Guarantee is amended prior thereto so that such additional
         Company Parity Preferred Securities benefit from the Bank Subordinated
         Guarantee in substantially the same manner as the Company Preferred
         Securities without any adverse effect on the holders of the Company
         Preferred Securities.

            (e) In purchasing Company Preferred Securities or Company Parity
Preferred Securities, each Preferred Securityholder agrees with the Bank and the
Company that the Bank, the Company and the Preferred Securityholders (i) will
treat Preferred Securityholders as holders of the Company Preferred Securities
or Company Parity Preferred Securities for all purposes, and not as the holders
of an interest in the Bank, the Cayman Islands Branch or in any other Person and
(ii) will follow allocations made by the Company pursuant to Section 4.4 of this
Agreement.

            Section 7.3       Company Preferred Securities.

            (a) Designation. There shall hereby be designated as a series of
preferred limited liability company interests in the Company a series identified
as the Company's "*% Noncumulative Company Preferred Securities", liquidation
preference $[1,000][25] per security and aggregate liquidation preference $*
(the "Company Preferred Securities").

            The holders of the Company Preferred Securities (or of any other
Company Security) will have no preemptive rights with respect to any limited
liability company interests in the Company or any other securities of the
Company convertible into or carrying rights or options to purchase any such
securities. Company Preferred Securities will not be convertible into Company
Common Securities or any other class or series of limited liability company
interests in the Company and will not be subject to any sinking fund or other
obligation of the Company for its repurchase or retirement.

            A Company Preferred Security shall be represented by the
corresponding Company Preferred Certificate.

            (b)   Dividends.

                  (i) Dividends on the Company Preferred Securities will be
         payable from the date of initial issuance on a noncumulative basis,
         [semi-annually in arrears on ____ and ____ of each year through ____
         20*, commencing on ____, 200*, and thereafter quarterly in arrears on
         ____ , ____ , ____ and ____ ][quarterly in arrears on ____, ____,

                                      -26-
<PAGE>
         ____ and ____] (or if any such day is not a Business Day, the next
         Business Day, but without any additional interest or other payment in
         respect of such delay) (each a "Dividend Payment Date" and each period
         from and including a Dividend Payment Date, or the date of initial
         issuance as applicable, to but not including the next Dividend Payment
         Date, a "Dividend Period") for the Dividend Period then ending, but
         only if the Company has legally available funds for such purpose and
         satisfies the other qualifications described below. Dividends will be
         payable on the liquidation preference [(i) for each Dividend Period
         through the Dividend Period ending on the Dividend Payment Date in ____
         20*, at a fixed rate per annum on the liquidation preference equal to
         *% (calculated on the basis of a year of twelve 30-day months) and (ii)
         for each dividend period commencing on such Dividend Payment Date and
         thereafter, at a floating rate per annum on the liquidation preference
         equal to *% above three-month LIBOR (calculated on the basis of the
         actual number of days elapsed in a 360-day year)][at a fixed rate per
         annum on the liquidation preference equal to *% (calculated on the
         basis of a year of twelve 30-day months)]. Dividends will be
         mandatorily due and payable in the circumstances described in Section
         7.3(b)(ii) below, except that dividends will never be mandatorily due
         and payable if the Capital Limitation described below in Section
         7.3(b)(iii) applies. If dividends on a Dividend Payment Date are
         neither mandatorily due and payable nor prohibited by application of
         the Capital Limitation, then (i) payment of dividends on the Company
         Preferred Securities will be limited by the Bank's Available
         Distributable Profits (see Section 7.3(b)(iv), below) and (ii) if the
         Bank delivers, on or before the tenth Business Day immediately
         preceding such Dividend Payment Date, an instruction (a "No Dividend
         Instruction") to the Company not to pay dividends on such Dividend
         Payment Date or to pay less than full dividends on such Dividend
         Payment Date, dividends payable on the related Dividend Payment Date
         will be limited as provided in such No Dividend Instruction (see
         Section 7.3(b)(v) below).

                  If any dividends will be payable on the Company Preferred
         Securities on a day that is not a Business Day, those dividends will
         instead be paid on the next Business Day. No interest or other payment
         will be due as a result of any such adjustment.

                  [LIBOR, with respect to a Determination Date, means the rate
         (expressed as a percentage per annum) for deposits in U.S. dollars for
         a three-month period commencing on the second London Banking Day
         immediately following that Determination Date that appears on Telerate
         Page 3750 as of 11:00 a.m. (London time) on that Determination Date. If
         such rate does not appear on Telerate Page 3750, LIBOR will be
         determined on the basis of the rates at which deposits in U.S. dollars
         for a three-month period commencing on the second London Banking Day
         immediately following that Determination Date and in a principal amount
         equal to an amount of not less than $[1,000,000] that is representative
         for a single transaction in such market at such time, are offered to
         prime banks in the London interbank market by four major banks in the
         London interbank market selected by the Calculation Agent, after
         consultation with the Company, at approximately 11:00 a.m., London
         time, on that Determination Date.]

                  [The Calculation Agent will request the principal London
         office of each of such banks to provide a quotation of its rate. If at
         least two such quotations are provided, LIBOR with respect to that
         Determination Date will be the arithmetic mean of such

                                      -27-
<PAGE>
         quotations. If fewer than two quotations are provided, LIBOR in respect
         of that Determination Date will be the arithmetic mean of the rates
         quoted by three major money center banks in New York City selected by
         the Calculation Agent, after consultation with the Company, at
         approximately 11:00 a.m., New York City time, on that Determination
         Date for loans in U.S. dollars to leading European banks for a
         three-month period commencing on the second London Banking Day
         immediately following that Determination Date and in a principal amount
         equal to an amount of not less than $[1,000,000]. However, if the banks
         selected by the Calculation Agent to provide quotations are not quoting
         as mentioned in this paragraph, LIBOR for the applicable period will be
         the same as LIBOR as determined on the previous Determination Date.]

                  All percentages resulting from any calculations on the Company
         Preferred Securities will be rounded, if necessary, to the nearest one
         hundred-thousandth of a percentage point, with five one-millionths of a
         percentage point rounded upward (e.g., 9.876545% (or .09876545) being
         rounded to 9.87655% (or .0987655)), and all dollar amounts used in or
         resulting from such calculation will be rounded to the nearest cent
         (with one-half cent being rounded upward).

                  (ii) The Company is required to pay dividends on the Company
         Preferred Securities in three circumstances, as follows:

                        (A) If the Bank declares or pays dividends or makes any
            other payment or distribution on any Bank Junior Obligations and the
            Capital Limitation does not apply, then the Company will be required
            to pay full dividends on the Company Preferred Securities during the
            one-year period beginning on and including the earlier of the date
            on which such dividend was declared or the date on which such
            dividend or other payment was made.

                        (B) If the Bank or any of its subsidiaries redeems,
            repurchases or otherwise acquires any Bank Parity Securities or Bank
            Junior Obligations for any consideration, except by conversion into
            or exchange for shares or Bank Junior Obligations and except as
            described below (and provided that the Capital Limitation does not
            apply), then the Company will be required to pay dividends on the
            Company Preferred Securities during the one-year period beginning on
            and including the date on which such redemption, repurchase or other
            acquisition occurred.

                        (C) If (x) the Bank or any of its subsidiaries declares
            or pays any dividends or makes any other payment or distribution on
            any Bank Parity Securities on any date and (y) during the Relevant
            Period ending on and including such date there occurred a Dividend
            Payment Date as to which the Company paid no dividends or less than
            full dividends on the Company Preferred Securities, and provided
            that the Capital Limitation does not apply, then on that date the
            Company will be required to pay a special dividend on the Company
            Preferred Securities. The special dividend will be payable on that
            date whether or not that date is otherwise a Dividend Payment Date
            and, if it is a Dividend Payment Date, will be in addition to any
            other dividends required to be paid on such Dividend

                                      -28-
<PAGE>
            Payment Date. The special dividend will be in an amount that, when
            taken together with dividends previously paid on the Company
            Preferred Securities during the Relevant Period, represents the same
            proportion of full dividends on the Company Preferred Securities for
            all Dividend Payment Dates during the Relevant Period that the
            dividend on Bank Parity Securities paid on such date bears to full
            dividends on such Bank Parity Securities for the Relevant Period.

Notwithstanding paragraph (B) above, the Company will not be required to pay
dividends solely as a result of (a) repurchases, redemptions or other
acquisitions of Bank Parity Securities or ordinary shares in connection with any
employment contract, benefit plan or other similar arrangement with or for the
benefit of any one or more employees, officers, directors or consultants, in
connection with a dividend reinvestment or shareholder share purchase plan or in
connection with the issuance of Bank Parity Securities or Bank Junior
Obligations (or securities convertible into or exercisable for such Bank Parity
Securities or Bank Junior Obligations) as consideration in an acquisition
transaction, (b) market-making in the Bank Parity Securities or ordinary shares
as part of the securities business of the Bank or any of its subsidiaries, (c)
the purchase of fractional interests in shares of Bank Parity Securities or Bank
Junior Obligations pursuant to the conversion or exchange provisions of such
Bank Parity Securities or Bank Junior Obligations or the security being
converted or exchanged, (d) any declaration of a dividend in connection with any
shareholder's rights plan, or the issuance of rights, shares or other property
under any shareholder's rights plan, or the redemption or repurchase of rights
pursuant to any such plan, or (e) any dividend in the form of shares, warrants,
options or other rights where the dividend shares or the shares issuable upon
exercise of such warrants, options or other rights are the same shares as that
on which the dividend is being paid or ranks pari passu with or junior to such
shares.

                  Any Dividend Payment Date or other date on which dividends on
         the Company Preferred Securities are required to be paid as described
         in paragraph (A), (B) or (C) above is a "Mandatory Dividend Payment
         Date." The amount of dividends required to be paid on any Mandatory
         Dividend Payment Date (after giving effect to the Capital Limitation,
         if applicable) is called the "Mandatory Dividend Payment Amount". If a
         Dividend Payment Date is a Mandatory Dividend Payment Date, the Company
         will be required to pay the Mandatory Dividend Payment Amount as
         dividends on that date whether or not there are Available Distributable
         Profits and whether or not interest is paid on the Subordinated Notes.

                  (iii) The prohibition on the payment of dividends on the
         Company Preferred Securities as described below is called the "Capital
         Limitation".

                  Unless the Swiss Federal Banking Commission expressly permits
         otherwise, the Company will not pay dividends on the Company Preferred
         Securities on any Dividend Payment Date (whether or not it is a
         Mandatory Dividend Payment Date) if on such date the Bank is not in
         compliance, or because of a distribution by the Bank or any of its
         subsidiaries of profits of the Bank (including a payment of dividends
         on the Company Preferred Securities) would not be in compliance, with
         the Swiss Federal Banking Commission's minimum capital adequacy
         requirements applicable to the Bank as then in effect.

                                      -29-
<PAGE>
                  (iv) The limitation or prohibition on the payment of dividends
         on the Company Preferred Securities as described below is called the
         "Distributable Profits Limitation". The Distributable Profits
         Limitation will not limit or prohibit payment of dividends up to the
         Mandatory Dividend Payment Amount as to a Mandatory Dividend Payment
         Date.

                  On or before the Dividend Payment Date in [June] of each year,
         the Bank will deliver a certificate to the Company (a "Distributable
         Profits Limitation Certificate") specifying: (i) the Distributable
         Profits of the Bank for the financial year ending on the preceding
         December 31 and (ii) the Available Distributable Profits for payment of
         dividends on the Company Preferred Securities on the Dividend Payment
         Dates in the then current year.

                  Unless the Company is required to pay as dividends the
         Mandatory Dividend Payment Amount for a Mandatory Dividend Payment
         Date, (A) the aggregate amount of dividends on the Company Preferred
         Securities that the Company may pay on the Dividend Payment Date in
         [June] of the current year may not exceed the lesser of full dividends
         and the Available Distributable Profits set forth in such Distributable
         Profits Limitation Certificate, and (B) the aggregate amount of
         dividends on the Company Preferred Securities that the Company may pay
         on any subsequent Dividend Payment Date in the current year [(or in
         [March] of the following year in the case of Dividend Payment Dates
         occurring after ____ 20*)][or in [March of the following year]] may not
         exceed the lesser of full dividends and the remaining amount of such
         Available Distributable Profits (after giving effect to the payment of
         dividends pursuant to this subclause or subclause (A), above).

                  (v) Except for the Mandatory Dividend Payment Amounts required
         to be paid on Mandatory Dividend Payment Dates:

                        (A) dividends on Company Preferred Securities will not
            be payable on a Dividend Payment Date if, on or before the tenth
            Business Day immediately preceding such Dividend Payment Date, the
            Bank delivers a No Dividend Instruction to the Company instructing
            it not to pay dividends on such Dividend Payment Date; and

                        (B) if, on or before the tenth Business Day immediately
            preceding such Dividend Payment Date, the Bank delivers a No
            Dividend Instruction to the Company limiting but not prohibiting the
            payment of dividends on such Dividend Payment Date, dividends on the
            Company Preferred Security will be payable on such Dividend Payment
            Date only to the extent permitted by such No Dividend Instruction.

                  If a No Dividend Instruction is given, then the Company must
         promptly give notice to holders of the Company Preferred Securities in
         the manner described in Section 7.3(i) of the fact that it has received
         a No Dividend Instruction and the amount of dividends, if any, that
         will be paid on the related Dividend Payment Date.

                                      -30-
<PAGE>
            (c) Additional Amounts. If the Company or the Trust is required to
withhold any taxes, duties or other governmental charges with respect to any
payment of dividends on the Company Preferred Securities or the Trust Preferred
Securities, the Company will be required to pay as additional amounts included
in the mandatory dividend payment (and the Bank will be required to include in
any related payment made by it under the Bank Subordinated Guarantee) an amount
sufficient that the net amount received by the holder of the Company Preferred
Securities or Trust Preferred Securities, as applicable, after the withholding,
will not be less than the Mandatory Dividend Payment Amount. However, the
Company will not be required to pay any such additional amounts to the extent
that the taxes, duties or other governmental charges are imposed or levied by
Switzerland or the Cayman Islands because the holder or beneficial owner of
Trust Preferred Securities or Company Preferred Securities (other than the
Trust):

                  (i) has some connection with Switzerland or the Cayman
         Islands, as applicable, other than being a holder or beneficial owner
         of those Trust Preferred Securities or Company Preferred Securities; or

                  (ii) has not made a declaration of non-residence in, or other
         lack of connection with, Switzerland or the Cayman Islands, as
         applicable, or any similar claim for exemption, if the Company has
         given the beneficial owner of those Trust Preferred Securities or
         Company Preferred Securities or its nominee at least 60 days' prior
         notice of an opportunity to make the declaration or claim.

            (d) Ranking and Liquidation Preference. The Company Preferred
Securities ordinarily will rank senior to the Company Common Securities as to
payment of dividends. However, the Bank has the right to shift the dividend
preference of the Company Preferred Securities to the Company Common Securities
on any Dividend Payment Dates to the extent that the Mandatory Dividend Payment
Amount then required to be paid as dividends on the Company Preferred Securities
(if any) is less than full dividends on the Company Preferred Securities. If the
Bank shifts the dividend preference to the Company Common Securities, the
interest payment received by the Company on the Subordinated Notes will be
returned as dividends to the Bank as holder of the Company Common Securities
before any dividends are paid on the Company Preferred Securities.

            As long as any Company Preferred Securities are outstanding, the
Bank, to the fullest extent permitted by law, will take no voluntary action to
cause the Company to dissolve or liquidate unless the Bank also liquidates. If
the Bank is liquidated, whether voluntarily or involuntarily (and whether in
connection with the occurrence of a Bankruptcy Event or otherwise), the Company
will be liquidated.

            If the Company dissolves, liquidates, or winds up, then, after the
claims of any creditors of the Company are satisfied, the holders of the Company
Preferred Securities will be entitled to receive, before any distribution of
assets is made to the holders of Company Junior Securities upon liquidation,
liquidating distributions in respect of the Company Preferred Securities in the
amount of the liquidation preference of their Company Preferred Securities plus
an amount equal to unpaid dividends, if any, on the Company Preferred Securities
with respect to the current Dividend Period accrued on a daily basis to the date
of liquidation, plus an amount

                                      -31-
<PAGE>
equal to unpaid Definitive Dividends for any prior Dividend Period, but without
interest and without accumulation of unpaid Nondefinitive Dividends for any
prior Dividend Period.

            Notwithstanding and as a limitation on the foregoing, the holders of
the Company Preferred Securities may not receive liquidating distributions in a
liquidation of the Company in an amount exceeding the liquidating distributions
to which they would have been entitled had they instead owned preferred shares
of the Bank having an aggregate liquidation preference equal to the aggregate
liquidation preference of the Company Preferred Securities and bearing dividends
at the rate of dividends applicable to the Company Preferred Securities. The
holders of the Company Common Securities will be entitled to share pro rata in
any remaining assets of the Company only after holders of the Company Preferred
Securities have received the amounts described above.

            (e) Voting Rights. Except as expressly required by applicable law,
or except as indicated below, the holders of Company Preferred Securities will
not be entitled to vote. In the event the holders of Company Preferred
Securities are entitled to vote as indicated below, each $[1,000] [25]
liquidation preference of Company Preferred Securities will be entitled to one
vote on matters on which holders of Company Preferred Securities are entitled to
vote.

            If at any time the aggregate of unpaid dividends equals or exceeds
an amount equal to [three semi-annual or six quarterly] dividend payments, the
holders of the Company Preferred Securities and any Company Parity Preferred
Securities, voting together as a single class, will have the exclusive right to
elect two additional Directors of their choosing. Holders of a majority (based
on the aggregate liquidation preference) of the Company Preferred Securities and
any Company Parity Preferred Securities may exercise this right by written
consent or at a meeting of holders of Company Preferred Securities and Company
Parity Preferred Securities called for such purpose. This right will continue
until all unpaid dividends have been paid in full or until full dividends have
been paid on the Company Preferred Securities and Company Parity Preferred
Securities for two consecutive Dividend Periods. While this right continues, any
vacancy in the office of the additional Directors may be filled only by the
holders of the Company Preferred Securities and any Company Parity Preferred
Securities voting as described above.

            A meeting of holders of Company Preferred Securities or Company
Parity Preferred Securities will be called at the request of holders of 25%
(based on the aggregate liquidation preference) of the Company Preferred
Securities and any Company Parity Preferred Securities.

            As long as any Company Preferred Securities and Company Parity
Preferred Securities are outstanding, the Company may not, without the consent
or vote of the holders of at least 66-2/3% of the outstanding Company Preferred
Securities and any Company Parity Preferred Securities (based on the aggregate
liquidation preference), voting together as a single class:

                  (i) change or remove any provision of this Agreement
         (including the terms of the Company Preferred Securities), issue any
         Company Parity Preferred Securities, redeem or repurchase any Company
         Common Securities, or consent to a change in the booking location of
         the issuance of the Subordinated Notes to a branch or

                                      -32-
<PAGE>
         other office of the Bank other than the Cayman Islands branch of the
         Bank, in each case, if such action would materially and adversely
         affect the rights, preferences, powers or privileges of the Company
         Preferred Securities and such Company Parity Preferred Securities;

                  (ii) to the fullest extent permitted by law, liquidate,
         dissolve or terminate the Company without the concurrent liquidation of
         the Bank;

                  (iii) amend or modify the Company's Investment Policies; or

                  (iv) merge, convert, consolidate, reorganize or effect any
         other business combination involving the Company, unless the resulting
         entity will have no class or series of equity securities either
         authorized or outstanding that ranks ahead of the Company Preferred
         Securities as to dividends or as to the distribution of assets upon
         liquidation, dissolution or winding up, except the same number of
         shares of such equity securities with the same preferences, conversion
         or other rights, voting powers, restrictions, limitations as to
         dividends or other distributions, qualifications or terms or conditions
         or redemption as the shares of equity securities of the Company that
         are authorized and outstanding immediately prior to such transaction,
         and each holder of Company Preferred Securities immediately prior to
         such transaction shall receive securities with the same preferences,
         conversion or other rights, voting powers, restrictions, limitations as
         to dividends or other distributions, qualifications or terms or
         conditions or redemption of the resulting entity as the Company
         Preferred Securities held by such holder immediately prior to the
         transaction.

Notwithstanding the foregoing, without the consent of any holder of Company
Preferred Securities or Company Parity Preferred Securities, the Bank may amend
or supplement this Agreement:

                  (i) to correct or supplement any provision in this Agreement
         which may be defective or inconsistent with any other provision
         therein, or to make any other provisions with respect to matters or
         questions arising under this Agreement, so long as any such action
         shall not materially adversely affect the interests of the holders of
         Company Preferred Securities; or

                  (ii) to cure any ambiguity or correct any mistake.

            As long as any Company Preferred Securities are outstanding, the
Company may not, without the consent of the holder of each outstanding Company
Preferred Security, authorize, create or increase the authorized amount of, or
issue any class or series of, any equity securities of or limited liability
company interests in the Company, or any warrants, options or other rights
convertible or exchangeable into any class or series of any equity securities of
or limited liability company interests in the Company, ranking prior to the
Company Preferred Securities, either as to dividend rights or rights on
dissolution, liquidation or winding-up of the Company.

            (f) Redemption. The Company Preferred Securities may not be redeemed
before the Dividend Payment Date regularly scheduled to occur in ____ 20*,
unless a Tax Event,

                                      -33-
<PAGE>
an Investment Company Act Event or a Capital Event occurs, in which case the
Company may redeem the Company Preferred Securities in whole (but not in part)
at any time on not less than 30 nor more than 60 days' notice. On or after the
Dividend Payment Date regularly scheduled to occur in ____ 20*, the Company may
redeem the Company Preferred Securities on any Dividend Payment Date for cash,
in whole or in part, on not less than 30 nor more than 60 days' notice.

            [The redemption price for such optional redemptions on or after the
Dividend Payment Date regularly scheduled to occur in _____ 200* and for
redemptions arising from a Tax Event, an Investment Company Act Event of a
Capital Event will be:

                  (i) 100% of the liquidation preference of the Company
         Preferred Securities being redeemed; plus

                  (ii) an amount equal to unpaid dividends, if any, on the
         Company Preferred Securities with respect to the current Dividend
         Period (whether or not declared) accrued on a daily basis to the date
         fixed for redemption; plus

                  (iii) an amount equal to unpaid Definitive Dividends for any
         prior Dividend Period, without interest and without accumulation of
         unpaid Nondefinitive Dividends for any prior Dividend Period.]

            [The redemption price for such redemptions on or after the regularly
scheduled Dividend Payment Date in ____ 20* will be:

                  (i) 100% of the liquidation preference of the Company
         Preferred Securities being redeemed; plus

                  (ii) an amount equal to unpaid dividends, if any, on the
         Company Preferred Securities with respect to the current Dividend
         Period (whether or not declared) accrued on a daily basis to the date
         fixed for redemption; plus

                  (iii) an amount equal to unpaid Definitive Dividends for any
         prior Dividend Period, without interest and without accumulation of
         unpaid Nondefinitive Dividends for any prior Dividend Period.

            The Company will also have the right to redeem the Company Preferred
Securities in whole (but not in part) at any time prior to the Dividend Payment
Date regularly scheduled to occur in ____ 20*, upon the occurrence of a Tax
Event, an Investment Company Act Event or a Capital Event. The redemption price
for a redemption arising out of a Tax Event resulting from a Change in Tax Law
and relating to the:

                  (i) imposition of tax on the Trust or the Company; or

                  (ii) the imposition of withholding tax on the Company's
         payment of dividends on the Company Preferred Securities, on the
         Trust's payment of dividends on the Trust Preferred Securities, on the
         Bank's payment of interest on the Subordinated Notes or on the Bank's
         payment under the Bank Subordinated Guarantee,

                                      -34-
<PAGE>
(which are the events described in clauses (A), (B) and (C) of the definition of
"Tax Event") will be the redemption price described above for optional
redemptions. Otherwise, the redemption price for such redemptions will be:

                  (i) the Make Whole Amount; plus

                  (ii) an amount equal to unpaid dividends, if any, on the
         Company Preferred Securities with respect to the current Dividend
         Period (whether or not declared) accrued on a daily basis to the date
         fixed for redemption; plus

                  (iii) an amount equal to unpaid Definitive Dividends for any
         prior Dividend Period, without interest and without accumulation of
         unpaid Nondefinitive Dividends for any prior Dividend Period.]

            [The Company will have until the Dividend Payment Date regularly
scheduled to occur in ____ 20* after the occurrence of a Tax Event, an
Investment Company Act Event or a Capital Event to exercise its right to redeem
the Company Preferred Securities.]

            Any redemption of Company Preferred Securities must comply with
applicable regulatory requirements, including the prior approval of the Swiss
Federal Banking Commission if then required under applicable guidelines or
policies of the Swiss Federal Banking Commission. If dividends on any Company
Preferred Securities are unpaid, no Company Preferred Securities may be redeemed
unless all outstanding Company Preferred Securities are redeemed and the Company
may not purchase or otherwise acquire any Company Preferred Securities, except
pursuant to a purchase or exchange offer made on the same terms to holders of
all outstanding Company Preferred Securities.

            The Company Preferred Securities will not be subject to any sinking
fund or mandatory redemption and will not be convertible into any other
securities of or limited liability company interests in the Company or any
securities of the Bank.

            As long as any Company Preferred Securities are outstanding, other
Company Parity Preferred Securities may not be redeemed or repurchased unless
the Company concurrently redeems an approximately equal proportion of the
aggregate liquidation preference of the outstanding Company Preferred Securities
or each rating agency then rating the Company Preferred Securities informs the
Company in writing that the redemption or repurchase of such Company Parity
Preferred Securities would not result in a reduction or withdrawal of the rating
then assigned by that rating agency to the Company Preferred Securities.

            If fewer than all of the outstanding Company Preferred Securities
are to be redeemed, the amount of Company Preferred Securities to be redeemed
shall be determined by the Board of Directors, and the securities to be redeemed
shall be determined by lot or pro rata as may be determined by the Board of
Directors in its sole discretion to be equitable; provided, that such method
satisfies any applicable requirements of any securities exchange on which the
Company Preferred Securities or any Trust Preferred Securities may then be
listed and, if the Company Preferred Securities or Trust Preferred Securities
are then held by DTC or its nominee in the form of a global security, any
applicable requirements of DTC. The Company will promptly notify the registrar
and transfer agent for the Company Preferred Securities in writing

                                      -35-
<PAGE>
of the securities selected for redemption and, in the case of any partial
redemption, the liquidation preference to be redeemed.

            In the event that payment of the redemption price in respect of any
Company Preferred Securities is improperly withheld or refused and not paid
either by the Company or by the Bank pursuant to the Bank Subordinated
Guarantee, dividends on such Company Preferred Securities, shall continue to
accumulate from the date fixed for redemption to the date of actual payment of
such Redemption Price.

            Any Company Preferred Securities redeemed shall be canceled. There
shall be no prescription period in respect of uncollected dividends on the
Company Preferred Securities.

            The Preferred Securityholders, by acceptance of such Company
Preferred Securities, acknowledge and agree to the subordination provisions in,
and other terms of, the Company Preferred Securities Guarantee.

            (g) Registrar and Transfer Agent. Wilmington Trust Company, or
another entity that the Bank may designate from time to time, will act as
registrar and transfer agent for the Company Preferred Securities.

            Registration of transfers of Company Preferred Securities will be
effected without charge by or on behalf of the Company, but upon payment of any
tax or other governmental charges that may be imposed in connection with any
transfer or exchange. The Company will not be required to register or cause to
be registered the transfer of Company Preferred Securities after such Company
Preferred Securities have been called for redemption.

            In the event of a partial redemption of the Company Preferred
Securities that would result in a delisting of the Trust Preferred Securities
from any securities exchange on which the Trust Preferred Securities are then
listed, the Company will redeem the Company Preferred Securities in whole.

            (h) Notices. Notices to holders of the Company Preferred Securities
will be mailed by first-class mail, postage prepaid, to the holders' addresses
appearing in the Company's records.

            (i) Governing Law. The Company Preferred Securities are governed by,
and shall be construed in accordance with, the laws of the State of Delaware
(without regard to principles of conflict of laws).

            (j) Additional Information. For so long as any Company Preferred
Securities are outstanding, the Company will furnish to holders and beneficial
owners of Trust Preferred Securities and Company Preferred Securities and to
prospective purchasers designated by such holders upon request the information
required to be delivered pursuant to the Securities Act.

            Section 7.4 General Provisions Regarding Subordinated Notes.

            (a) The Company may sell the Subordinated Notes only upon the
affirmative vote of both a majority of the Board of Directors and the holders of
two-thirds (based on the

                                      -36-
<PAGE>
aggregate liquidation preference) of the Company Preferred Securities and
Company Parity Preferred Securities (if any), voting together as a single class.

            (b) The Company may not agree to any modification or amendment to
the Subordinated Notes as long as any Company Preferred Securities or Company
Parity Preferred Securities (if any) are outstanding unless holders of
two-thirds (based on the aggregate liquidation preference) of the Company
Preferred Securities and Company Parity Preferred Securities (if any), voting as
a class, consent to such modification or amendment. Such consent to modification
or amendment of the Subordinated Notes shall not be required if (i) the proposed
amendment or modification would not materially and adversely affect the rights,
preferences, powers or privileges of the holders of the Company Preferred Stock
and (ii) the Company has received a letter from each of Moody's Investors
Service Inc. and Standard & Poor's Ratings Services to the effect that such
amendment will not result in a downgrading of its respective rating then
assigned to the Company Preferred Securities.

                                  ARTICLE VIII
                               VOTING AND MEETINGS

            Section 8.1 Voting Rights of Preferred Securityholders. ii) Except
as shall be otherwise expressly provided in Section 7.3(e) or otherwise herein,
in the By-Laws or in any Certificate of Designations adopted by the Board of
Directors or as otherwise required by the Delaware Act, the Preferred
Securityholders shall have no right or power to vote on any question or matter
or in any proceeding or to be represented at, or to receive notice of, any
meeting of Securityholders.

            (b) Notwithstanding that Preferred Securityholders holding Company
Preferred Securities are entitled to vote or consent under the circumstances
described in this Agreement, the By-Laws or any Certificate of Designations, any
of the Company Preferred Securities that are owned by the Bank, the Common
Securityholder, the Company or any of their respective Affiliates, either
directly or indirectly, shall not be entitled to vote or consent and shall, for
the purposes of such vote or consent, be treated as if they were not outstanding
except for Company Preferred Securities purchased or acquired by the Bank or its
Affiliates in connection with transactions effected by or for the account of
customers of the Bank or any of its Affiliates or in connection with the
distribution or trading of or market-making in connection with such Company
Preferred Securities; provided, however, that Persons (other than Affiliates of
the Bank) to whom the Bank or any of its Affiliates have pledged Company
Preferred Securities may vote or consent with respect to such pledged Company
Preferred Securities pursuant to the terms of such pledge.

            Section 8.2 Voting Rights of Common Securityholders. Except as
otherwise provided herein, and except as otherwise required by the Delaware Act,
all voting rights of the Securityholders shall be vested exclusively in the
Common Securityholders. The Company Common Securities shall entitle the Common
Securityholders to vote in proportion to their percentage ownership interest in
the Company upon all matters upon which Common Securityholders have the right to
vote. All Common Securityholders shall have the right to vote

                                      -37-

separately as a class on any matter on which the Common Securityholders have the
right to vote regardless of the voting rights of any other Securityholder.

            Section 8.3 Meetings of the Securityholders.

            (a) Meetings of the Securityholders of any class or of all classes
of Securities may be called at any time by the Chairman of the Board (if any),
the President or the Board of Directors or as provided by this Agreement or the
By-Laws. A meeting of holders of Company Preferred Securities or Company Parity
Preferred Securities will be called at the request of holders of 25% (based on
the aggregate liquidation preference) of the Company Preferred Securities and
any Company Parity Preferred Securities. Except to the extent otherwise
provided, the following provisions shall apply to meetings of Securityholders.

            (b) Securityholders may vote in person or by proxy at such meeting.
Whenever a vote, consent or approval of Securityholders is permitted or required
under this Agreement, such vote, consent or approval may be given at a meeting
of Securityholders or by written consent.

            (c) Each Securityholder may authorize any Person to act for it by
proxy on all matters in which a Securityholder is entitled to participate,
including waiving notice of any meeting, or voting or participating at a
meeting. Every proxy must be signed by the Securityholder or its
attorney-in-fact. Every proxy shall be revocable at the pleasure of the
Securityholder executing it at any time before it is voted.

            (d) Each meeting of Securityholders shall be conducted by the Board
of Directors or by such other Person that the Board of Directors may designate.

            (e) Any required approval of Preferred Securityholders may be given

purpose or at a meeting of Securityholders of the Company or pursuant to written
consent. The Board of Directors shall cause a notice of any meeting at which
Preferred Securityholders holding Company Preferred Securities or Company Parity
Preferred Securities are entitled to vote pursuant to Section 7.3, any
Certificate of Designations adopted by the Board of Directors or Article XIV of
this Agreement, or of any matter upon which action may be taken by written
consent of such Preferred Securityholders, to be mailed to each holder of record
of the Company Preferred Securities or Company Parity Preferred Securities. Each
such notice shall include a statement setting forth (i) the date of such meeting
or the date by which such action is to be taken, (ii) a description of any
action proposed to be taken at such meeting on which such Preferred
Securityholders are entitled to vote or of such matters upon which written
consent is sought and (iii) instructions for the delivery of proxies or
consents.

            (f) Subject to Section 8.3(e) of this Agreement, the Board of
Directors, in their sole discretion, shall establish all other provisions
relating to meetings of Securityholders, including notice of the time, place or
purpose of any meeting at which any matter is to be voted on by any
Securityholders, waiver of any such notice, action by consent without a meeting,
the establishment of a record date, quorum requirements, voting in person or by

                                    DIVIDENDS

            Section 9.1 Dividends.

            (a) Subject to the terms of this Article IX, Preferred
Securityholders shall receive periodic dividends, if any, in accordance with
Article VII of this Agreement or any Certificate of Designations duly adopted by
the Board of Directors, and Common Securityholders shall receive periodic
dividends and distributions, subject to Article VII of this Agreement or any
Certificate of Designations duly adopted by the Board of Directors, and to the
provisions of the Delaware Act, when, as and if declared by the Board of
Directors, in its discretion. A dividend shall constitute a distribution within
the meaning of the Delaware Act.

            (b) Securityholder shall not be entitled to receive any dividend or
other distribution with respect to any dividend payment date (and any such
dividend or other distribution shall not be considered due and payable),
irrespective of whether such dividend or other distribution is payable
automatically or has been declared by the Directors, until such time as the
Company shall have funds legally available for the payment of such dividend to
such Securityholder pursuant to the terms of this Agreement and the Delaware
Act, and notwithstanding any provision of Section 18-606 of the Delaware Act to
the contrary, until such time, a Securityholder shall not have the status of a
creditor of the Company, or the remedies available to a creditor of the Company;
provided however that a Preferred Securityholder and a holder of Preferred Trust
Securities may exercise such rights or remedies as provided herein or in any
other agreement or document.

            Section 9.2 Limitations on Distributions. Notwithstanding any
provision to the contrary contained in this Agreement, the Company shall not
make a distribution (including a dividend) to any Securityholder on account of a
Company Security if such distribution would violate Section 18-607 of the
Delaware Act or other applicable law.

            Section 9.3 No Dividend Instruction.

            (a) At any time, and from time to time, the Common Securityholder
may, at its option, deliver to the Company a written instruction in the form of
Annex H hereof on or before the tenth Business Day immediately preceding any
dividend payment date for the Company Preferred Securities instructing the
Company not to pay dividends, or to limit but not prohibit dividends, on such
Dividend Payment Date (a "No Dividend Instruction"). As described in Section
7.3(b)(v), upon receipt of a No Dividend Instruction with respect to the Company
Preferred Securities and except to the extent permitted by such No Dividend
Instruction, no dividend shall become due and payable on the Company Preferred
Securities (or any Company Parity Preferred Securities or Company Junior
Securities (other than the Company Common Securities)) on the dividend payment
date immediately succeeding the date of receipt of such instruction. A No
Dividend Instruction shall only be effective for the dividend payment date
immediately succeeding the date of receipt of such instruction by the Company.
If such dividend payment date is a Mandatory Dividend Payment Date, then such No
Dividend Instruction shall be of no force or effect. If at any time there is
more than one Common Securityholder, a No Dividend Instruction shall not be
effective until signed by all of the Common Securityholders.

                                      -39-
<PAGE>
            (b) Notwithstanding Section 9.3(a), dividends on the Company
Preferred Securities will be definitive, due and payable on each Mandatory
Dividend Payment Date whether or not a No Dividend Instruction has been given or
is deemed given with respect to such Mandatory Dividend Payment Date.

            Section 10.1 Financial Statements. The Board of Directors shall, as
soon as available after the end of each Financial Year of the Company, cause to
be prepared and mailed to each Common Securityholder of record the audited
financial statements of the Company for such Financial Year prepared in
accordance with generally accepted accounting principles. So long as any Company
Preferred Securities are outstanding, the Company will furnish to holders and
beneficial owners of Company Preferred Securities and to prospective purchasers
designated by such holders upon request, the most recent annual audited
financial statements and, if prepared, semi-annual unaudited financial
statements of the Company then available, together with a brief description of
the Company's business.

            Section 10.2 Limitation on Access to Records. Each Securityholder
has the right, subject to this Agreement and to reasonable standards established
by the Board of Directors to obtain from the Company from time to time upon
reasonable request for any purpose reasonably related to such Securityholder's
interest as a member in the Company, information regarding the affairs of the
Company. Notwithstanding any provision of this Agreement, the Board of Directors
may, to the maximum extent permitted by law, keep, or cause to be kept,
confidential from the Preferred Securityholders, for such period of time as the
Board of Directors deems reasonable, any information the disclosure of which the
Board of Directors reasonably believes to be in the nature of trade secrets or
other information the disclosure of which the Board of Directors in good faith
believe is not in the best interest of the Company or could damage the Company
or its business or which the Company or the Board of Directors are required by
law or by an agreement with any Person to keep confidential.

            Section 10.3 Accounting Method. For both financial and tax reporting
purposes and for purposes of determining profits and losses, the books and
records of the Company shall be kept on the accrual method of accounting applied
in a consistent manner and shall reflect all Company transactions and be
appropriate and adequate for the Company's business.

            Section 10.4 Annual Audit. As soon as practical after the end of
each Financial Year, but not later than 90 days after such end, the financial
statements of the Company shall be audited by a firm of independent certified
public accountants selected by the Board of Directors, and such financial
statements shall be accompanied by a report of such accountants containing their
opinion. The cost of such audits shall be an expense of the Company and paid by
the Company.

                  Section 11.1      Company Tax Returns.

                  (a) The Common Securityholder is hereby designated as the
Company's "Tax Matters Partner" under Section 6231(a)(7) of the Code and shall
have all the powers and responsibilities of such position as provided in the
Code. The Tax Matters Partner is specifically directed and authorized to take
whatever steps the Bank, in its discretion, deems necessary or desirable to
perfect such designation, including filing any forms or documents with the
Internal Revenue Service and taking such other action as may from time to time
be required under the Treasury Regulations. Expenses incurred by the Tax Matters
Partner in its capacity as such shall be borne by the Company.

                  (b) The Tax Matters Partner shall cause to be prepared and
timely filed all tax returns required to be filed for the Company. The Tax
Matters Partner may, in its discretion, cause the Company to make or refrain
from making any federal, state or local income or other tax elections for the
Company that it deems necessary or advisable, including, without limitation, any
election under Section 754 of the Code or any successor provision.

                  Section 11.2 Tax Reports. The Tax Matters Partner shall, as
promptly as practicable and in any event within 90 days of the end of each
Financial Year, cause to be prepared and mailed by the Company to each Preferred
Securityholder of record Internal Revenue Service Schedule K-1 and any other
forms that are necessary or advisable in order to permit the Securityholders to
comply with U.S. federal and any other income tax requirements.

                  Section 11.3 Taxation as a Partnership. The Company shall take
any necessary steps to be treated as a partnership for U.S. federal income tax
purposes and shall not file any election to be treated as anything other than a
partnership for such purposes.

                  Section 11.4 Taxation of Securityholders. As provided in
Section 4.4(b), profits shall be allocated to the Preferred Securityholders on a
when-paid basis. The Securityholders intend that allocations of income and loss

of income under this Agreement.

                  the Securityholders;

                           (b) all expenses incurred in connection with any

                  investigation and preparation) and the amount of any judgment
                  or settlement paid in connection therewith (other than

                  Section 13.1 Right of Assignee to Become a Preferred
Securityholder. An assignee of Company Preferred Securities or Company Parity

its Securities (including by any redemption or other repurchase by the Company)
or as otherwise provided herein.

                  Section 13.3 Persons Deemed Preferred Securityholders. The
Company may treat the Person in whose name any Company Preferred Certificate
shall be registered on the books and records of the Company as the sole holder
of such Company Preferred Certificate and

                                      -42-
<PAGE>
of the Company Preferred Securities or Company Parity Preferred Securities
represented by such Company Preferred Certificate for purposes of receiving
dividends or other distributions and for all other purposes whatsoever and,
accordingly, shall, to the fullest extent permitted by law, not be bound to
recognize any equitable or other claim to or interest in such Company Preferred
Certificate or in the Company Preferred Securities or Company Parity Preferred
Securities represented by such Company Preferred Certificate on the part of any
other Person, whether or not the Company shall have actual or other notice
thereof. Notwithstanding the foregoing or anything to the contrary herein, the
Company agrees that at any time that the Trust shall be a holder of any Company
Preferred Securities, each holder of a preferred certificate issued by the Trust
shall, upon presentation to the Company or the Registrar of reasonable evidence
thereof, have the right to the fullest extent permitted by law and without the
need for any other action of any other person, including the trustee under the
Trust and any other holder of any other of such preferred certificates, (a) to
enforce, in the name of the Trust, the Trust's rights under the Company
Preferred Securities and the Bank Subordinated Guarantee represented by the
preferred certificates of such holder and (b) to withdraw from the Trust upon
written notice to such trustee and the Company and hold directly the underlying
Company Preferred Securities represented by such preferred certificates (in
which case such holder will be entitled directly to enforce its rights under the
Bank Subordinated Guarantee).

                  Section 13.4      The Company Preferred Certificates.

                  (a) Company Preferred Certificates evidencing fractions of
Company Preferred Securities or Company Parity Preferred Securities shall not be
issued. Each Company Preferred Certificate shall be signed, manually or by
facsimile, by the President, any Vice-President or the Secretary of the Company.
Company Preferred Certificates, other than Company Preferred Certificates held
by a Trust, shall also be signed, manually or by facsimile, by the Registrar.
Company Preferred Certificates bearing the signatures of individuals who were,
at the time when such signatures shall have been affixed, authorized to sign on
behalf of the Company shall be validly issued notwithstanding that such
individuals or any of them shall have ceased to be so authorized prior to the
delivery of such Company Preferred Certificates or did not hold such offices at
the date of delivery of such Company Preferred Certificates. A transferee of a
Company Preferred Certificate shall become a Securityholder, upon due
registration of such Company Preferred Certificate in such transferee's name
pursuant to Section 13.5.

                  (b) Upon their original issuance, Company Preferred
Certificates evidencing the Company Preferred Securities or Company Parity
Preferred Securities shall be issued in the form of one or more Company
Preferred Certificates.

                  Section 13.5      Transfer of Company Preferred Certificates.

                  (a) The Board of Directors shall provide for the registration
and transfer of each class of Company Preferred Certificates in a record thereof
(each a "Securities Register") and shall appoint a securities registrar (the
"Registrar") and transfer agent (the "Transfer Agent") to act on its behalf;
provided, however, that without any action on the part of the Board of Directors
being necessary, Wilmington Trust Company is hereby appointed as the initial
Registrar and Transfer Agent. Subject to the other provisions of this Article
XIII, upon surrender

                                      -43-
<PAGE>
for registration of transfer of any Company Preferred Certificate, the Board of
Directors shall cause one or more new Company Preferred Certificates to be
issued in the name of the designated transferee or transferees. Every Company
Preferred Certificate surrendered for registration of transfer shall be
accompanied by a written instrument of transfer in form satisfactory to the
Board of Directors duly executed by the Preferred Securityholder or his or her
attorney duly authorized in writing. Any registration of transfer shall be
effected upon the Transfer Agent being satisfied with the documents of title and
identity of the Person making the request upon the receipt by the Transfer Agent
of any applicable certificate relating to transfer restrictions as described
below, and subject to such reasonable regulations as the Company may from time
to time establish. Each Company Preferred Certificate surrendered for
registration of transfer shall be canceled by the Board of Directors. A
transferee of a Company Preferred Certificate shall be admitted to the Company
as a Preferred Securityholder and shall be entitled to the rights and subject to
the obligations of a Preferred Securityholder hereunder upon receipt by such
transferee of a Company Preferred Certificate. By acceptance of a Company
Preferred Certificate, each transferee shall be bound by this Agreement. The
transferor of a Preferred Certificate, in whole, shall cease to be a Preferred
Securityholder at the time that the transferee of such Company Preferred
Certificate is admitted to the Company as a Preferred Securityholder in
accordance with this Section 13.5.

                  (b) Upon surrender for registration of transfer of any Company
Preferred Certificate at the office or agency of the Company or the Registrar
maintained for that purpose, subject to Section 13.6, the Company shall deliver
or cause to be delivered to the Registrar in a form duly executed on behalf of
the Company in the manner provided for in Section 13.4(a), and the Registrar
shall countersign in the manner provided in and to the extent required by
Section 13.4(a) and deliver, in the name of the designated transferee or
transferees, one or more new Company Preferred Certificates in authorized
denominations of a like aggregate liquidation preference dated the date of
execution by such Registrar.

                  The Registrar shall not be required, (i) to issue, register
the transfer of or exchange any Company Preferred Security or Company Parity
Preferred Securities during a period beginning at the opening of business 15
days before the day of selection for redemption of such Company Preferred
Securities or Company Parity Preferred Securities and ending at the close of
business on the day of mailing of the notice of redemption, or (ii) to register
the transfer of or exchange any Company Preferred Security or Company Parity
Preferred Securities so selected for redemption in whole or in part, except, in
the case of any such Company Preferred Security or Company Parity Preferred
Securities to be redeemed in part, any portion thereof not to be redeemed.

                  No service charge shall be made for any registration of
transfer or exchange of Company Preferred Certificates, but the Registrar may
require payment of a sum sufficient to cover any tax or governmental charge that
may be imposed in connection with any transfer or exchange of Company Preferred
Certificates.

                  Section 13.6 Mutilated, Destroyed, Lost or Stolen Company
Preferred Certificates. If (a) any mutilated Company Preferred Certificate shall
be surrendered to the Registrar, or if the Registrar shall receive evidence to
its satisfaction of the destruction, loss or theft of any Company Preferred
Certificate, and (b) there shall be delivered to the Registrar and

                                      -44-
<PAGE>
the Company such security or indemnity as may be required by them to save each
of them harmless, then in the absence of notice that such Company Preferred
Certificate shall have been acquired by a bona fide purchaser, the Company shall
sign, the Registrar shall countersign to the extent required under Section
13.4(a), and the Company and the Registrar shall make available for delivery
(all in the manner provided for in Section 13.4), in exchange for or in lieu of
any mutilated, destroyed, lost or stolen Company Preferred Certificate, a new
Company Preferred Certificate of like class, tenor and denomination. In
connection with the issuance of any new Company Preferred Certificate under this
Section 13.6, the Company or the Registrar may require the payment of a sum
sufficient to cover any tax or other governmental charge that may be imposed in
connection therewith. Any duplicate Company Preferred Certificate issued
pursuant to this Section shall constitute conclusive evidence of a limited
liability company interest in the Company corresponding to that evidenced by the
lost, stolen or destroyed Company Preferred Certificate, as if originally
issued, whether or not the lost, stolen or destroyed Company Preferred
Certificate shall be found at any time.

                  Section 13.7      Restrictions on Transfers of Securities.

                  (a) Company Preferred Securities or Company Parity Preferred
Securities may not be sold or otherwise transferred unless such securities are
registered under the Securities Act or an exemption from the registration
requirements thereof is available, and the Company Preferred Certificates shall
bear a legend to this effect unless the Bank and the Company determine otherwise
in compliance with applicable law.

                  (b) No Company Preferred Security or Company Parity Preferred
Security shall be transferred, in whole or in part, except in accordance with
the terms and conditions set forth in this Agreement or any Certificate of
Designations. Any transfer or purported transfer of any Company Preferred
Security or Company Parity Preferred Security not made in accordance with this
Agreement shall be null and void.

                  (c) The Company Common Securities may be sold, assigned or
otherwise transferred by the Bank to a direct or indirect wholly owned
subsidiary of the Bank, which subsidiary shall be admitted as a member of the
Company with respect to the Company Common Securities transferred upon such
Person's execution and delivery of a counterpart of this Agreement.

                        MERGERS, CONSOLIDATIONS AND SALES

                  Section 14.1 The Company. The Company may not, without the
prior approval of holders of at least 66-2/3% of the outstanding Company
Preferred Securities and any Company Parity Preferred Securities (based on the
aggregate liquidation preference), voting as a single class, merge, convert,
consolidate, reorganize or effect any other business combination involving the
Company, unless the resulting entity will have no class or series of equity
securities either authorized or outstanding that ranks ahead of the Company
Preferred Securities or the Company Parity Preferred Securities as to dividends
or as to the distribution of assets upon liquidation,

                                      -45-

dissolution or winding up, except the same number of shares of such equity
securities with the same preferences, conversion or other rights, voting powers,
restrictions, limitations as to dividends or other distributions, qualifications
or terms or conditions or redemption as the shares of equity securities of the
Company that are authorized and outstanding immediately prior to such
transaction, and each holder of Company Preferred Securities or the Company
Parity Preferred Securities immediately prior to such transaction shall receive
securities with the same preferences, conversion or other rights, voting powers,
restrictions, limitations as to dividends or other distributions, qualifications
or terms or conditions or redemption of the resulting entity as the Company
Preferred Securities or the Company Parity Preferred Securities held by such
holder immediately prior to the transaction.

                                   ARTICLE XV
                    DISSOLUTION, LIQUIDATION AND TERMINATION

                  Section 15.1 No Dissolution. The Company shall not be
dissolved by the admission of Securityholders. The death, insanity, retirement,
resignation, expulsion, bankruptcy or dissolution of a Securityholder, or the
occurrence of any other event which terminates the continued membership of a
Securityholder in the Company, shall not in and of itself cause the Company to
be dissolved and its affairs wound up. Upon the occurrence of any such event,
the business of the Company shall be continued without dissolution. The
bankruptcy of a Securityholder (as defined in Section 18-101(1) and 18-304 of
the Delaware Act) shall not cause a Securityholder to cease to be a member of
the Company. Notwithstanding any other provision of this Agreement, each
Securityholder waives any right it might have under the Delaware Act to agree in

                  shall have continued undischarged and unstayed for a period of
                  90 days; or a decree or order of a court having jurisdiction
                  in the premises for the appointment of a receiver, liquidator,

<PAGE>
                  similar official in bankruptcy or insolvency of the Company or
                  of all or substantially all of its property, or shall make an
                  assignment for the benefit of creditors, or shall admit in
                  writing its inability to pay its debts generally as they
                  become due and its willingness to be adjudged a bankrupt, or
                  limited liability company action shall be taken by the Company
                  in furtherance of any of the aforesaid purposes;

                           (b)      the Bank is liquidated;

                           (c) the entry of a decree of judicial dissolution of
                  the Company under Section 18-802 of the Delaware Act;

                           (d) in connection with the redemption, repurchase or

                  Delaware Act or this Agreement; or

                           (g) the entry of a judgment initiating judicial
                  liquidation in respect of the Bank under Swiss law or any
                  other liquidation of the Bank under Swiss law.

                  Section 15.3 Notice of Dissolution. Upon the dissolution of
the Company, the Board of Directors shall promptly notify the Securityholders of
such dissolution.

                  Section 15.4 Liquidation. Upon dissolution of the Company, the
Board of Directors or, in the event that the dissolution is caused by an event
described in Sections 15.2(b) or (c) of this Agreement and there are no
Directors, a Person or Persons who may be approved by the Preferred
Securityholders holding not less than a majority in liquidation amount, as
liquidating trustees, shall immediately commence to wind up the Company's
affairs; provided, however, that a reasonable time shall be allowed for the
orderly liquidation of the assets of the Company and the satisfaction of
liabilities to creditors so as to minimize the losses attendant upon a
liquidation. The proceeds of liquidation shall be distributed, as realized, in
the manner provided in Section 18-804 of the Delaware Act, subject to the
provisions of Section 15.5.

                  Section 15.5 Certain Restrictions on Liquidation Payments. In
the event of any voluntary or involuntary dissolution of the Company (other than

holding Company Preferred Securities or Company Parity Preferred Securities at
the time outstanding shall be entitled to receive out of the assets of the
Company legally available for distribution to Securityholders, before any
distribution of assets is made to Common Securityholders or any other Company
Junior Securities, liquidating distributions in respect of the Company Preferred
Securities or Company Parity Preferred Securities in the amount of the
liquidation preference, plus an amount equal to unpaid dividends, if any,
thereon with respect to the current Dividend Payment accrued on a daily basis to
the date of liquidation, plus an amount equal to unpaid Definitive Dividends for
any prior Dividend Period, but without interest and without accumulation of
unpaid Nondefinitive Dividends for any prior dividend period. If, upon any such
liquidation, the liquidating distribution can be paid only in part because the
Company has insufficient assets available to pay in full the aggregate

                                      -47-
<PAGE>
Liquidation Distribution, then the amounts payable directly by the Company on
the Company Preferred Securities or Company Parity Preferred Securities shall be
paid on a pro rata basis.

                  Section 15.6 Termination. The Company shall terminate when all
of the assets of the Company have been distributed in the manner provided for in
this Article XV, and the Certificate of Formation shall have been canceled in
the manner required by the Delaware Act.

                                   ARTICLE XVI
                                  MISCELLANEOUS

                  Section 16.1 Amendments. This Agreement may be amended by a
written instrument executed by an Officer designated by the Board of Directors
without the consent of any Preferred Securityholder; provided, however, that no
amendment shall be made, and any such purported amendment shall be void and
ineffective, to the extent that such amendment (a) would have a material adverse
effect on a Preferred Securityholder (including, without limitation, amendments
to Sections 6.2 and 6.7), (b) would result in causing the Company to be treated
as anything other than a partnership for purposes of United States federal
income taxation would result in the Company being deemed to be required to
register under the Investment Company Act, or (c) has not received the prior
requisite approval of the holders of the Company Preferred Securities and the
Company Parity Preferred Securities, as applicable, as may be expressly provided
in this Agreement, the By-Laws or any Certificate of Designations duly adopted
by the Board of Directors.

                  Section 16.2 Amendment of Certificate of Formation. In the
event this Agreement shall be amended pursuant to Section 16.1, the Board of
Directors shall cause the Certificate of Formation to be amended to reflect such
change if it deems such amendment of the Certificate of Formation to be
necessary or appropriate.

                  Section 16.3 Successors. This Agreement shall be binding as to
the executors, administrators, estates, heirs and legal successors, or nominees
or representatives, of the Securityholders.

                  Section 16.4 Law; Severability. THIS AGREEMENT SHALL BE
GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF DELAWARE.
In particular, this Agreement shall be construed to the maximum extent possible
to comply with all of the terms and conditions of the Delaware Act. If,
nevertheless, it shall be determined by a court of competent jurisdiction that
any provisions or wording of this Agreement shall be invalid or unenforceable
under the Delaware Act or other applicable law, such invalidity or
unenforceability shall not invalidate the entire Agreement. In that case, this
Agreement shall be construed so as to limit any term or provision so as to make
it enforceable or valid within the requirements of applicable law, and, in the
event such term or provisions cannot be so limited, this Agreement shall be
construed to omit such invalid or unenforceable provisions. If it shall be
determined by a court of competent jurisdiction that any provision relating to
the distributions and allocations of the Company or to any fee payable by the
Company is invalid or unenforceable, this Agreement shall be construed or
interpreted so as (a) to make it enforceable

                                      -48-
<PAGE>
or valid and (b) to make the distributions and allocations as closely equivalent
to those set forth in this Agreement as is permissible under applicable law.

                  Section 16.5 Filings. Following the execution and delivery of
this Agreement, the Board of Directors shall cause to be promptly prepared any
documents required to be filed and recorded under the Delaware Act, and the
Board of Directors shall cause to be promptly filed and recorded each such
document in accordance with the Delaware Act and, to the extent required by
local law, to be filed and recorded or notice thereof to be published in the
appropriate place in each jurisdiction in which the Company may hereafter
establish a place of business. The Board of Directors shall also promptly cause
to be filed, recorded and published such statements of fictitious business name
and any other notices, certificates, statements or other instruments required by
any provision of any applicable law of the United States or any state or other
jurisdiction which governs the conduct of its business from time to time.

                  Section 16.6 Power of Attorney. Each Preferred Securityholder
does hereby constitute and appoint each Person specifically authorized by the
Board of Directors to act as its true and lawful representative and
attorney-in-fact, in its name, place and stead to make, execute, sign, deliver
and file (a) any amendment of the Certificate of Formation required because of
an amendment to this Agreement or in order to effectuate any change in the
ownership of the Company Securities, (b) any amendments to this Agreement made
in accordance with the terms hereof and (c) all such other instruments,
documents and certificates which may from time to time be required by the laws
of the United States of America, the State of Delaware or any other
jurisdiction, or any political subdivision or agency thereof, to effectuate,
implement and continue the valid and subsisting existence of the Company or to
dissolve the Company or for any other purpose consistent with this Agreement and
the transactions contemplated hereby.

                  The power of attorney granted hereby is coupled with an
interest and shall (a) survive and not be affected by the subsequent death,
incapacity, disability, dissolution, termination or bankruptcy of the Preferred
Securityholder granting the same or the transfer of all or any portion of such
Preferred Securityholder's Preferred Securities and (b) extend to such Preferred
Securityholder's successors, assigns and legal representatives.

                  Section 16.7      Exculpation.

                  (a) No Director or Officer shall have personal liability to
the Company or the Securityholders for monetary damages for breach of, in the
case of a Director, such Director's fiduciary duty (if any) or, in the case of a
Director or an Officer, for any act or omission performed or omitted by such
Director or Officer in good faith on behalf of the Company, except for such
Director's or Officer's gross negligence or willful misconduct.

                  (b) Each Director and Officer shall be fully protected in
relying in good faith upon the records of the Company and upon such information,
opinions, reports or statements presented to the Company by any Person as to
matters that such Director or Officer reasonably believes are within such other
Person's professional or expert competence and who has been selected with
reasonable care by or on behalf of the Company, including information, opinions,
reports or statements as to the value and amount of the assets, liabilities,
profits, losses, or any

                                      -49-
<PAGE>
other facts pertinent to the existence and amount of assets from which
distributions to Securityholders might properly be paid.

                  Section 16.8 Indemnification. To the fullest extent permitted
by applicable law, each Director and Officer shall be entitled to
indemnification from the Company for any loss, damage, claim or expense
(including reasonable attorney's fees) incurred by such Director or Officer by
reason of any act or omission performed or omitted by such Director or Officer
in good faith on behalf of the Company and in a manner reasonably believed to be
within the scope of authority conferred on such Director or Officer by this
Agreement, except with respect to any act or omission determined by a court of
competent jurisdiction to have constituted gross negligence or wilful misconduct
of such Director or Officer; provided, however, that any indemnity under this
Section 16.8 shall be provided out of and to the extent of Company assets only,
and no Securityholder shall have any personal liability on account thereof. The
right to indemnification under this Section 16.8 is a contract right. The
Company may purchase and maintain insurance to protect any director or officer
against liability asserted against him or her, or incurred by him or her,
arising out of his or her status as such.

                  Without limiting the foregoing, the Company's directors shall
have no personal liability to the Company or its Securityholders for monetary
damages (i) for not voting to take enforcement action with respect to the
Subordinated Notes or other Affiliate Securities owned by the Company, if any,
prior to the occurrence of a Bankruptcy Event or (ii) at any time for breach of
any such director's fiduciary duty (if any) except for such director's gross
negligence or willful misconduct.

                  Section 16.9 Additional Documents. Each Preferred
Securityholder, upon the request of the Board of Directors, agrees to perform
all further acts and execute, acknowledge and deliver any documents that may be
reasonably necessary to carry out the provisions of this Agreement.

                  Section 16.10 Notices. All notices provided for in this

            The Administrator shall perform its duties hereunder diligently and
with the same standard of care exercised by a prudent person in connection with
the performance of the same or similar duties and, in no event with less care

                      UBS PREFERRED FUNDING COMPANY LLC IX

            These By-laws have been established as the By-laws of UBS Preferred
Funding Company LLC IX, a Delaware limited liability company (the "Company")
pursuant to the Amended and Restated Limited Liability Company Agreement, dated
as of ____ __, 200* (as from time to time amended, modified or supplemented, the
"Agreement"), pursuant to which the Company's existence has been continued, and,
together with the Agreement and Annexes, C, E, F, G, H and I thereto, are deemed
to be the limited liability company agreement of the Company for purposes of the
Delaware Act. In the event of any inconsistency between the Agreement and these
By-laws, the provisions of the Agreement shall control.

            Capitalized terms used and not otherwise defined herein shall have
the meanings ascribed to them in the Agreement.

                                    ARTICLE I
                                 SECURITYHOLDERS

            Section 1.1. Annual Meetings. An annual meeting of Securityholders
may be held at such date, time and place either within or without the State of
Delaware if and as may be decided and designated by the Board of Directors from
time to time; provided, however the Company shall not be required to have an
annual meeting of Securityholders. Any other proper business may be transacted
at the annual meeting.

            Section 1.2. Special Meetings. Special meetings of Securityholders
may be called at any time by the Chairman of the Board, if any, the President or
the Board of Directors, to be held at such date, time and place either within or
without the State of Delaware as may be stated in the notice of the meeting. A
special meeting of Securityholders shall be called by the Secretary upon the
written request, stating the purpose of the meeting, of Securityholders who
together own of record a majority of the Securities entitled to vote at such
meeting.

            Section 1.3. Notice of Meetings. Whenever Securityholders are
required or permitted to take any action at a meeting, a written notice of the
meeting shall be given which shall state the place, date and hour of the
meeting, and, in the case of a special meeting, the purpose or purposes for
which the meeting is called. Unless otherwise provided by law, the written
notice of any meeting shall be given not less than ten nor more than sixty days
before the date of the meeting to each Securityholder entitled to vote at such
meeting. If mailed, such notice shall be deemed to be given when deposited in
the United States mail, postage prepaid, directed to the Securityholder at such
Securityholder's address as it appears on the records of the Company.

            Section 1.4. Adjournments. Any meeting of Securityholders, annual or
special, may be adjourned from time to time, to reconvene at the same or some
other place, and notice

                                      C-1
<PAGE>
need not be given of any such adjourned meeting if the time and place thereof
are announced at the meeting at which the adjournment is taken. At the adjourned
meeting the Company may transact any business which might have been transacted
at the original meeting. If the adjournment is for more than thirty days, or if
after the adjournment a new record date is fixed for the adjourned meeting, a
notice of the adjourned meeting shall be given to each Securityholder of record
entitled to vote at the meeting.

            Section 1.5. Quorum. At each meeting of Securityholders, except
where otherwise provided by law or the Agreement or these By-laws, the holders
of at least 50% of the Securities entitled to vote on a matter at the meeting,
present in person or represented by proxy, shall constitute a quorum. In the
absence of a quorum of the holders of Securities entitled to vote on a matter,
the holders of a majority of the Securities present or represented may adjourn
such meeting from time to time in the manner provided by Section 1.4 of these
By-laws until a quorum shall be so present or represented. Securities other than
Common Securities belonging on the record date for the meeting to the Company or
an Affiliate of the Company shall neither be entitled to vote nor be counted for
quorum purposes.

            Section 1.6. Organization. Meetings of Securityholders shall be
presided over by the Chairman of the Board, if any, or in the absence of the
Chairman of the Board by the President, or in the absence of the President by a
Vice President, or in the absence of the foregoing persons, by a chairman
designated by the Board of Directors, or in the absence of such designation, by
a chairman chosen at the meeting. The Secretary, or in the absence of the
Secretary, an Assistant Secretary, shall act as secretary of the meeting, but in
the absence of the Secretary and any Assistant Secretary, the chairman of the
meeting may appoint any person to act as secretary of the meeting.

            Section 1.7. Voting; Proxies. Unless otherwise provided in the
Agreement, each Securityholder entitled to vote at any meeting of
Securityholders shall have voting power proportionate to the outstanding amount,
based on initial issue price, of the Securities held by such Securityholder that
have voting power upon the matter in question. Each Securityholder entitled to
vote at a meeting of Securityholders or to express consent or dissent to action
in writing without a meeting may authorize another person or persons to act for
such Securityholder by proxy, but no such proxy shall be voted or acted upon
after three years from its date, unless the proxy provides for a longer period.
A duly executed proxy shall be irrevocable if it states that it is irrevocable
and if, and only as long as, it is coupled with an interest sufficient in law to
support an irrevocable power, regardless of whether the interest with which it
is coupled is an interest in the Securities themselves or an interest in the
Company generally. A Securityholder may revoke any proxy which is not
irrevocable by attending the meeting and voting in person or by filing an
instrument in writing revoking the proxy or another duly executed proxy bearing
a later date with the Secretary of the Company. Voting at meetings of
Securityholders need not be by written ballot unless the holders of a majority
of the outstanding Securities entitled to vote thereon present in person or
represented by proxy at such meeting shall so determine. Directors shall be
designated, removed and replaced as provided in the Agreement and Article II
hereof. Other than in the case of any matter expressly set forth in the
Agreement for which a higher vote may be required, the affirmative vote of the
holders of a majority of the Securities present in person or represented by
proxy at the meeting and entitled to vote on the subject matter shall be the act
of the Securityholders.

            Section 1.8. Fixing Date for Determination of Securityholders of
Record. In order that the Company may determine the Securityholders entitled to
notice of or to vote at any meeting of Securityholders or any adjournment
thereof, the Board of Directors may fix a record date, which record date shall
not precede the date upon which the resolution fixing the record date is adopted
by the Board of Directors, and which record date shall not be more than sixty
nor less than ten days before the date of such meeting. If no record date is
fixed by the Board of Directors, the record date for determining Securityholders
entitled to notice of or to vote at a meeting of Securityholders shall be at the
close of business on the day next preceding the day on which notice is given,
or, if notice is waived, at the close of business on the day next preceding the
day on which the meeting is held. A determination of Securityholders of record
entitled to notice of or to vote at a meeting of Securityholders shall apply to
any adjournment of the meeting; provided, however, that the Board of Directors
may fix a new record date for the adjourned meeting.

            In order that the Company may determine the Securityholders entitled
to consent to action in writing without a meeting, the Board of Directors may
fix a record date, which record date shall not precede the date upon which the
resolution fixing the record date is adopted by the Board of Directors, and
which date shall not be more than ten days after the date upon which the
resolution fixing the record date is adopted by the Board of Directors. If no
record date has been fixed by the Board of Directors, the record date for
determining Securityholders entitled to consent to action in writing without a
meeting, when no prior action by the Board of Directors is required by law,
shall be the first date on which a signed written consent setting forth the
action taken or proposed to be taken is delivered to the Company by delivery to
(a) its registered office in the State of Delaware, (b) its principal place of
business, or (c) an Officer or agent of the Company having custody of the book
in which proceedings of meetings of Securityholders are recorded. Delivery made
to the Company's registered office shall be by hand or by certified or
registered mail, return receipt requested. If no record date has been fixed by
the Board of Directors and prior action by the Board of Directors is required by
law, the record date for determining Securityholders entitled to consent to
action in writing without a meeting shall be at the close of business on the day
on which the Board of Directors adopts the resolution taking such prior action.

            In order that the Company may determine the Securityholders entitled
to receive payment of any distribution or allotment of any rights or the
Securityholders entitled to exercise any rights in respect of any exchange of
Securities, or for the purpose of any other lawful action, the Board of
Directors may fix a record date, which record date shall not precede the date
upon which the resolution fixing the record date is adopted, and which record
date shall be not more than sixty days prior to such action. If no record date
is fixed, the record date for determining Securityholders for any such purpose
shall be at the close of business on the day on which the Board of Directors
adopts the resolution relating thereto.

            Section 1.9. List of Securityholders Entitled to Vote. The Secretary
shall prepare and make, at least ten days before every meeting of
Securityholders, a complete list of the Securityholders entitled to vote at the
meeting, arranged in alphabetical order, and showing the address of each
Securityholder and the amount of Securities registered in the name of each
Securityholder. Such list shall be open to the examination of any
Securityholder, for any purpose germane to the meeting, during ordinary business
hours, for a period of at least ten days

                                      C-3
<PAGE>
prior to the meeting, either at a place within the city where the meeting is to
be held, which place shall be specified in the notice of the meeting, or, if not
so specified, at the place where the meeting is to be held. The list shall also
be produced and kept at the time and place of the meeting during the whole time
thereof and may be inspected by any Securityholder who is present.

            Section 1.10. Consent of Securityholders in Lieu of Meeting. Unless
otherwise provided in the Agreement or by law, any action required by law to be
taken at any annual or special meeting of Securityholders of the Company, or any
action which may be taken at any annual or special meeting of such
Securityholders, may be taken without a meeting, without prior notice and
without a vote, if a consent or consents in writing, setting forth the action so
taken, shall be signed by the holders of outstanding Securities having not less
than the minimum number of votes that would be necessary to authorize or take
such action at a meeting at which all Securities entitled to vote thereon were
present and voted and shall be delivered to the Company by delivery to (a) its
registered office in the State of Delaware by hand or by certified mail or
registered mail, return receipt requested, (b) its principal place of business,
or (c) an Officer or agent of the Company having custody of the book in which
proceedings of meetings of Securityholders are recorded. Every written consent
shall bear the date of signature of each Securityholder who signs the consent
and no written consent shall be effective to take the action referred to therein
unless, within sixty days of the earliest dated consent delivered in the manner
required by this By-Law to the Company, written consents signed by holders
representing a sufficient amount of Securities to take action are delivered to
the Company by delivery to (a) its registered office in the State of Delaware by
hand or by certified or registered mail, return receipt requested, (b) its
principal place of business, or (c) an Officer or agent of the Company having
custody of the book in which proceedings of meetings of Securityholders are
recorded. Prompt notice of the taking of the action without a meeting by less
than unanimous written consent shall be given to those Securityholders who have
not consented in writing.

                                   ARTICLE II
                               BOARD OF DIRECTORS

            2.1. Number; Powers; By-laws. The business and affairs of the
Company shall be managed by or under the direction of a Board composed of not
less than three nor more than five Directors. The Board shall manage the
business and affairs of the Company and may exercise all powers in connection
therewith, except for such powers as are required to be exercised by
Securityholders, all in accordance with the Agreement, these By-laws and
applicable law. Except to the extent that the Board or the Securityholders
confer such authority on a Director, no Director shall have the authority to
bind the Company.

            2.2. Voting Power. Each Director shall, in the consideration of any
matter by the Board, have a single vote at the time such vote is taken or made
(whether at a meeting or by written consent). Except where a greater percentage
approval may be provided for herein or in the Agreement or by law, an action
shall be deemed approved by the Board only if it has been approved by a majority
of the Directors.

            2.3. Quorum. At all meetings of the Board, the presence of at least
a majority of Directors shall constitute a quorum for the transaction of
business. In case at any meeting of the

                                      C-4
<PAGE>
Board a quorum shall not be present, any Director present may adjourn the
meeting from time to time until a quorum shall be present.

            2.4. Designation; Removal; Replacement. The term of office of a
Director shall be until the earliest of the following events: (i) his or her
successor is designated or (ii) he or she resigns or is removed. Any Director
may be removed, with or without cause by majority vote of the remaining
Directors. In the event of the resignation, removal or death of a Director, such
Director shall be replaced by another person designated by majority vote of the
remaining Directors. Any Director may resign at any time upon written notice to
the Board of Directors or to the President or the Secretary of the Company. Such
resignation shall take effect at the time specified therein, and unless
otherwise specified therein no acceptance of such resignation shall be necessary
to make it effective.

            Section 2.5. Regular Meetings. Regular meetings of the Board of
Directors may be held at such places within or without the State of Delaware and
at such times as the Board may from time to time determine, and if so determined
notice thereof need not be given.

            Section 2.6. Special Meetings. Special meetings of the Board of
Directors may be held at any time or place within or without the State of
Delaware whenever called by the Chairman of the Board, by the President or by
any two Directors. Reasonable notice thereof shall be given by the person or
persons calling the meeting.

            Section 2.7. Participation in Meetings by Conference Telephone
Permitted. Unless otherwise restricted by the Agreement or these By-laws, the
Board of Directors, or any committee designated by the Board, may participate in
a meeting of the Board or of such committee, as the case may be, by means of
conference telephone or similar communications equipment by means of which all
persons participating in the meeting can hear each other, and participation in a
meeting pursuant to this By-Law shall constitute presence in person at such
meeting.

            Section 2.8. Organization. Meetings of the Board of Directors shall
be presided over by the Chairman of the Board, or in the absence of the Chairman
of the Board by the President, or in their absence, by a chairman chosen at the

any person to act as secretary of the meeting.

            Section 2.9. Action by Directors Without a Meeting. Unless otherwise
restricted by the Agreement or these By-laws, any action required or permitted

                                   ARTICLE III
                                   COMMITTEES

            Section 3.1. Committees. The Board of Directors may, by resolution
of the Board adopted by majority vote, designate one or more committees, each
committee to consist of

                                      C-5
<PAGE>
one or more of the Directors of the Company. Any such committee, to the extent
provided in the resolution of the Board of Directors or in these By-laws, shall
have and may exercise all the powers and authority of the Board of Directors in
the management of the business and affairs of the Company, and may authorize the
seal of the Company to be affixed to all papers which may require it; but no
such committee shall have the power or authority in reference to amending the
Certificate of Formation, adopting an agreement of merger, consolidation or
conversion, recommending to the Securityholders the sale, lease or exchange of
all or substantially all of the Company's property and assets, recommending to
the Securityholders a dissolution of the Company or a revocation of a
dissolution, amending these By-laws and, unless the resolution, these By-laws or
the Agreement expressly so provides, no such committee shall have the power or
authority to authorize the issuance of Securities, to adopt a certificate of
ownership and merger, consolidation or conversion or to remove or indemnify
Officers or Directors.

            Section 3.2. Committee Rules. Unless the Board of Directors
otherwise provides, each committee designated by the Board may adopt, amend and
repeal rules for the conduct of its business. In the absence of a provision by
the Board or a provision in the rules of such committee to the contrary, a
majority of the members of such committee shall constitute a quorum for the
transaction of business, the vote of a majority of the members present at a
meeting at the time of such vote if a quorum is then present shall be the act of
such committee, and in other respects each committee shall conduct its business
in the same manner as the Board conducts its business pursuant to Article II of
these By-laws.

                                   ARTICLE IV
                                    OFFICERS

            Section 4.1. Officers; Election. As soon as practicable after the
annual meeting of Securityholders in each year, the Board of Directors shall
elect a President and a Secretary, and may also elect one or more Vice
Presidents, one or more Assistant Vice Presidents, one or more Assistant
Secretaries, a Treasurer and one or more Assistant Treasurers and such other
Officers as the Board may deem desirable or appropriate and may give any of them
such further designations or alternate titles as it considers desirable. Any
number of offices may be held by the same person unless the Agreement or these
By-laws otherwise provide.

            Section 4.2. Term of Office; Resignation; Removal; Vacancies. Unless
otherwise provided in the resolution of the Board of Directors electing any
Officer, each Officer shall hold office until his or her successor is elected
and qualified or until his or her earlier resignation or removal. Any Officer
may resign at any time upon written notice to the Board or to the President or
the Secretary of the Company. Such resignation shall take effect at the time
specified therein, and, unless otherwise specified therein, no acceptance of
such resignation shall be necessary to make it effective. The Board may remove
any Officer with or without cause at any time. Any such removal shall be without
prejudice to the contractual rights of such Officer, if any, with the Company,
but the election of an Officer shall not of itself create contractual rights.
Any vacancy occurring in any office of the Company by death, resignation,
removal or otherwise may be filled by the Board at any regular or special
meeting.

            Section 4.3. Powers and Duties. The Officers of the Company shall
have such powers and duties in the management of the Company as shall be stated
in these By-laws or in a

                                      C-6
<PAGE>
resolution of the Board of Directors which is not inconsistent with these
By-laws and, to the extent not so stated, as generally pertain to comparable
offices in a corporation organized under the General Corporation Law of the
State of Delaware, subject to the control of the Board. The Secretary shall have
the duty to record the proceedings of the meetings of the Securityholders, the
Board of Directors and any committees in a book to be kept for that purpose. The
Board may require any Officer, agent or employee to give security for the
faithful performance of his or her duties.

                                    ARTICLE V
                                   SECURITIES

            Section 5.1. Certificates for Securities. The Preferred Securities
in the Company shall be registered in certificated form. If such certificate is
manually countersigned by a transfer agent or by a registrar, any other
signature on the certificate may be a facsimile. In case any Officer who has
signed or whose facsimile signature has been placed upon a certificate shall
have ceased to be such Officer before such certificate is issued, it may be
issued by the Company with the same effect as if such person were such Officer
at the date of issue.

            Section 5.2. Lost, Stolen or Destroyed Certificates; Issuance of New
Certificates. The Company may issue a new certificate representing Securities in
the place of any certificate theretofore issued by it, alleged to have been
lost, stolen or destroyed, and the Company may require the owner of the lost,
stolen or destroyed certificate, or such owner's legal representative, to give
the Company a bond sufficient to indemnify it against any claim that may be made
against it on account of the alleged loss, theft or destruction of any such
certificate or the issuance of such new certificate or uncertificated
Securities.

                                   ARTICLE VI
                                  MISCELLANEOUS

            Section 6.1. Seal. The Company may have a company seal which shall
have the name of the Company inscribed thereon and shall be in such form as may
be approved from time to time by the Board of Directors. The Company seal may be
used by causing it or a facsimile thereof to be impressed or affixed or in any
other manner reproduced.

            Section 6.2. Waiver of Notice of Meetings of Securityholders,
Directors and Committees. Whenever notice is required to be given by law or
under any provision of the Agreement or these By-laws, a written waiver thereof,
signed by the person entitled to notice, whether before or after the time stated
therein, shall be deemed equivalent to notice. Attendance of a person at a
meeting shall constitute a waiver of notice of such meeting, except when the
person attends a meeting for the express purpose of objecting, at the beginning
of the meeting, to the transaction of any business because the meeting is not
lawfully called or convened. Neither the business to be transacted at, nor the
purpose of, any regular or special meeting of the Securityholders, Directors or
a committee of Directors need be specified in any written waiver of notice
unless so required by the Agreement or these By-laws.

            Section 6.3. Indemnification of Directors, Officers and Employees.
The Company shall indemnify to the full extent permitted under the Delaware Act
and other

                                      C-7
<PAGE>
applicable law any person made or threatened to be made a party to any action,
suit or proceeding, whether civil, criminal, administrative or investigative, by
reason of the fact that such person or such person's testator or intestate is or
was a Director, Officer or employee of the Company or serves or served at the
request of the Company any other enterprise as a Director, director, officer or
employee except for such Director's or Officer's gross negligence or willful
misconduct. Expenses, including reasonable attorneys' fees, incurred by any such
person in defending any such action, suit or proceeding shall be paid or
reimbursed by the Company promptly upon receipt by it of an undertaking of such
person to repay such expenses if it shall ultimately be determined that such
person is not entitled to be indemnified by the Company. The rights provided to
any person by this By-Law shall be enforceable against the Company by such
person who shall be presumed to have relied upon it in serving or continuing to
serve as a Director, Officer or employee as provided above. No amendment of this
By-Law shall impair the rights of any person arising at any time with respect to
events occurring prior to such amendment. For purposes of this By-Law, the term
"Company" shall include any predecessor of the Company and any constituent
company (including any constituent of a constituent) absorbed by the Company in
a consolidation or merger; the term "other enterprise" shall include any limited
liability company, corporation, partnership, joint venture, trust or employee
benefit plan; service "at the request of the Company" shall include service as a
Director, Officer or employee of the Company which imposes duties on, or
involves services by, such Director, Officer or employee with respect to an
employee benefit plan, its participants or beneficiaries; any excise taxes
assessed on a person with respect to an employee benefit plan shall be deemed to
be indemnifiable expenses; and action by a person with respect to an employee
benefit plan which such person reasonably believes to be in the interest of the
participants and beneficiaries of such plan shall be deemed to be action not
opposed to the best interests of the Company. The rights conferred on any Person
by this Section 6.3 shall not be exclusive of any other rights which such Person
may have or hereafter acquire under any statute, provision of these By-Laws, the
Agreement, any other agreement, vote of Securityholders or disinterested
Directors or otherwise. The Company's obligation, if any, to indemnify any
Person who was or is serving at its request as a director, officer, employee or
agent of any other enterprise shall be reduced by any amount such Person may
collect as indemnification from such other enterprise. Any repeal or
modification of the foregoing provisions of this Section 6.4 shall not adversely
affect any right of protection hereunder of any Person in respect of any act or
omission occurring prior to the time of such repeal or modification.

            Section 6.4. Interested Directors; Quorum. No contract or
transaction between the Company and one or more of its Directors or Officers, or
between the Company and any other limited liability company, corporation,
partnership, association or other organization in which one or more of its
Directors or Officers are Directors or officers, or have a financial interest,
shall be void or voidable solely for this reason, or solely because the Director
or Officer is present at or participates in the meeting of the Board of
Directors or committee thereof which authorizes the contract or transaction, or
solely because his or her or their votes are counted for such purpose, if: (1)
the material facts as to his or her relationship or interest and as to the
contract or transaction are disclosed or are known to the Board or the
committee, and the Board or committee in good faith authorizes the contract or
transaction by the affirmative votes of disinterested Directors, even though the
disinterested Directors be less than a quorum; or (2) the material facts as to
his or her relationship or interest and as to the contract or transaction are
disclosed or are known to the Securityholders entitled to vote thereon, and the
contract or

                                      C-8
<PAGE>
transaction is specifically approved in good faith by vote of the
Securityholders; or (3) the contract or transaction is fair as to the Company as
of the time it is authorized, approved or ratified, by the Board, a committee
thereof or the Securityholders. Common or interested Directors may be counted in
determining the presence of a quorum at a meeting of the Board of Directors or
of a committee which authorizes the contract or transaction.

            Section 6.5. Form of Records. Any records maintained by the Company
in the regular course of its business, including its Securities ledger, books of
account and minute books, may be kept on, or be in the form of, punch cards,
magnetic tape or disk, photographs, microphotographs or any other information
storage device, provided that the records so kept can be converted into clearly
legible form within a reasonable time. The Company shall so convert any records
so kept upon the request of any person entitled to inspect the same.

            Section 6.6. Amendment of By-laws. These By-laws may be amended or
repealed, and new by-laws adopted, by the Board of Directors in accordance with
the Agreement.

            Section 6.7. Governing Law. These By-laws shall be governed by and
construed in accordance with the laws of the State of Delaware (without regard
to principles of conflict of laws).

                               INVESTMENT POLICIES

      The Company will maintain its assets in a manner that will not require the
Company to be registered as an investment company under the 1940 Act. The
Company will not (i) invest in the securities of other issuers for the purpose
of exercising control over such issuers, (ii) underwrite securities of other
issuers, (iii) actively trade in investments, (iv) offer securities in exchange
for property or (v) make loans to third parties, including, without limitation,
officers, directors or other affiliates of the Company.

      The Company may not hold or invest in any securities other than the
Subordinated Notes issued by the Cayman Islands branch of the Bank with an
aggregate principal amount of $o or other securities issued by the Bank acting
through a branch, agency or other office located outside of the United States or
by a non-U.S. branch of a non-U.S. subsidiary of the Bank (together, "Eligible
Investments"). With respect to any Eligible Investments other than the
Subordinated Notes purchased by the Company, the terms thereof must be
established in good faith to reflect, to the extent deemed advisable by the
Bank, arm's-length market terms at the time of purchase and the purchase by the
Company of Eligible Investments must be approved by the affirmative vote of a
majority of the entire Board of Directors.

      Upon receipt at of the principal amount of the Subordinated Notes, the
Company will either invest the principal amount received in other Eligible
Investments or, if the Company elects to redeem the Company Preferred Securities
at such time (subject to having received prior approval of the Swiss Federal
Banking Commission to do so, if then required), apply such amount to the
redemption price of the Company Preferred Securities.

      Capitalized terms not defined herein have the meanings ascribed to such
terms in the Amended and Restated Limited Liability Company Agreement, dated
____ __, 200*, of UBS Preferred Funding Company LLC IX, as the same may be
amended from time to time.

                                   ARTICLE II
                               TRUST INDENTURE ACT

            Section 2.01. Trust Indenture Act; Application.

            (a) This Guarantee is subject to the provisions of the Trust
Indenture Act that are required to be part of this Guarantee and shall, to the
extent applicable, be governed by such provisions. A term defined in the Trust
Indenture Act has the same meaning when used in this Guarantee, unless otherwise
defined in this Guarantee or unless the context otherwise requires.

            (b) If and to the extent that any provision of this Guarantee
limits, qualifies or conflicts with the duties imposed by Sections 310 to 317,
inclusive, of the Trust Indenture Act, such imposed duties shall control.

            Section 2.02. Lists of Holders of Securities.

            (a) The Guarantee Trustee shall preserve in as current a form as is
reasonably practicable the most recent list available to it of the names and
addresses of Holders of Company Preferred Securities. If the Guarantee Trustee
is not the Registrar, the Guarantor shall furnish to the Guarantee Trustee
semi-annually on or before _______ and _______ of each year through _______ 20-,
and thereafter on or before _______ __, _______, _______ and _______ of each
year, and at such other times as the Guarantee Trustee may request in writing, a
list, in such form and as of such date as the Guarantee Trustee may reasonably
require, containing all the information in the possession or control of the
Registrar, the Guarantor or any of its paying agents other than the Guarantee
Trustee as to the names and addresses of Holders of Company Preferred
Securities.

            (b) The Guarantee Trustee shall comply with its obligations under

Preferred Securities), such reports as are required by Section 313 of the Trust
Indenture Act, if any, in the form and in the manner provided by Section 313 of
the Trust Indenture Act. The Guarantee Trustee shall also comply with the
requirements of Section 313(d) of the Trust Indenture Act.

            Section 2.04. Periodic Reports to Guarantee Trustee. The Guarantor
shall provide to the Guarantee Trustee such documents, reports and information
as required by Section 314 (if any) and the compliance certificate required by
Section 314 of the Trust Indenture Act in the form, in the manner and at the
times required by Section 314 of the Trust Indenture Act. Delivery of such
reports, information and documents to the Guarantee Trustee is for informational
purposes only and the Guarantee Trustee's receipt of such shall not constitute
constructive notice of any information contained therein or determinable from
information contained therein, including the Guarantor's compliance with any of
its covenants hereunder (as to which the Guarantee Trustee is entitled to rely
exclusively on Officers' Certificates).

            Section 2.05. Evidence of Compliance with Conditions Precedent. The
Guarantor shall provide to the Guarantee Trustee such evidence of compliance
with any conditions precedent, if any, provided for in this Guarantee that
relate to any of the matters set forth in Section 314(c) of the Trust Indenture
Act. Any certificate or opinion required to be given by an officer pursuant to
Section 314(c)(1) may be given in the form of an Officers' Certificate and shall
include:

                 (a) a statement that each officer signing the Officers'
      Certificate has read the covenant or condition and the definition relating
      thereto;

                 (b) a brief statement of the nature and scope of the
      examination or investigation undertaken by each officer in rendering the
      Officers' Certificate;

                 (c) a statement that each such officer has made such
      examination or investigation as, in such officer's opinion, is necessary
      to enable such officer to express an informed opinion as to whether or not
      such covenant or condition has been complied with; and

                 (d) a statement as to whether, in the opinion of each such
      officer, such condition or covenant has been complied with.

            Section 2.06. Events of Default; Waiver. The Holders of a Majority
in liquidation amount of the Company Preferred Securities may, by vote, on
behalf of the Holders of all of the Company Preferred Securities, waive any past
Event of Default and its consequences except an Event of Default in respect of a
covenant or provision hereof which cannot be modified or amended without the
consent of each Holder of Company Preferred Securities (and, for so long as the
Initial Holder is the Holder of the Company Preferred Securities, also of each
Holder of Trust Preferred Securities). Upon such waiver, any such Event of
Default shall cease to exist, and any Event of Default arising therefrom shall
be deemed to have been cured, for every purpose of this Guarantee, but no such
waiver shall extend to any subsequent or other default or Event of Default or
impair any right consequent thereon.

            Section 2.07. Event of Default; Notice.

                                      -9-
<PAGE>
            (a) The Guarantee Trustee shall, within 90 days after the occurrence
of an Event of Default, transmit by mail, first class postage prepaid, to the
Holders of the Company Preferred Securities (and, for so long as the Initial
Holder is the Holder of the Company Preferred Securities, also to the Holders of
the Trust Preferred Securities), notices of all Events of Default actually known
to a Responsible Officer of the Guarantee Trustee, unless such defaults have
been cured before the giving of such notice; provided, that, the Guarantee
Trustee shall be protected in withholding such notice if and so long as a
Responsible Officer of the Guarantee Trustee in good faith determines that the
withholding of such notice is in the interests of the Holders of the Company
Preferred Securities.

            (b) The Guarantee Trustee shall not be deemed to have knowledge of
any Event of Default unless a Responsible Officer of the Guarantee Trustee shall
have received written notice, or a Responsible Officer of the Guarantee Trustee
charged with the administration of this Guarantee shall have obtained actual
knowledge, of such Event of Default.

            Section 2.08. Rights of Holders.

            (a) The Holders of a Majority in liquidation amount of the Company
Preferred Securities have the right to direct the time, method and place of
conducting any proceeding for any remedy available to the Guarantee Trustee in
respect of this Guarantee or exercising any trust or power conferred upon the
Guarantee Trustee under this Guarantee.

            (b) If the Guarantee Trustee fails to enforce its rights under this
Guarantee after a Holder of Company Preferred Securities has made a written
request, such Holder of Company Preferred Securities may institute a legal
proceeding directly against the Guarantor to enforce the Guarantee Trustee's
rights under Article 4, without first instituting a legal proceeding against the
Company, the Guarantee Trustee or any other person or entity. Notwithstanding
the foregoing, if the Guarantor has failed to make a Guarantee Payment, a Holder
of Company Preferred Securities may directly institute a proceeding in such
Holder's own name against the Guarantor for enforcement of Article 4 for such
payment.

            (c) Notwithstanding any other provision of this Agreement, for so
long as the Trust is the Holder of any Company Preferred Securities, any Holder
of Trust Preferred Securities shall have the right, upon the occurrence of an
Event of Default, to institute a suit directly against the Guarantor for
enforcement of its payment and other obligations hereunder with respect to a
Corresponding Amount of Company Preferred Securities.

            Section 2.09. Conflicting Interests. The LLC Agreement shall be
deemed to be specifically described in this Guarantee for the purposes of clause
(i) of the first proviso contained in Section 310(b) of the Trust Indenture Act.

            Section 2.10. Powers, Duties and Rights of Guarantee Trustee.

                                      -10-
<PAGE>
            (a) This Guarantee shall be held by the Guarantee Trustee for the
benefit of the Holders of the Company Preferred Securities, and the Guarantee
Trustee shall not transfer this Guarantee to any Person except a Holder of
Company Preferred Securities exercising his or her rights pursuant to Section
2.08(b) or to a Successor Guarantee Trustee on acceptance by such Successor
Guarantee Trustee of its appointment to act as Successor Guarantee Trustee. The
right, title and interest of the Guarantee Trustee shall automatically vest in
any Successor Guarantee Trustee, and such vesting and cessation of title shall
be effective whether or not conveyancing documents have been executed and
delivered pursuant to the appointment of such Successor Guarantee Trustee.

            (b) If an Event of Default actually known to a Responsible Officer
of the Guarantee Trustee has occurred and is continuing, the Guarantee Trustee
shall enforce this Guarantee for the benefit of the Holders of the Company
Preferred Securities.

            (c) The Guarantee Trustee, before the occurrence of any Event of
Default and after the curing or waiver of all Events of Default that may have
occurred, shall undertake to perform only such duties as are specifically set
forth in this Guarantee, and no implied covenants shall be read into this
Guarantee against the Guarantee Trustee. In case an Event of Default has
occurred (that has not been cured or waived pursuant to Section 2.06 and is
actually known to a Responsible Officer of the Guarantee Trustee), the Guarantee
Trustee shall exercise such of the rights and powers vested in it by this
Guarantee, and use the same degree of care and skill in its exercise thereof, as
a prudent person would exercise or use under the circumstances in the conduct of
his or her own affairs.

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

                 (i) prior to the occurrence of any Event of Default and after
      the curing or waiving of all such Events of Default that may have
      occurred:

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

                     (B) in the absence of bad faith on the part of the
            Guarantee Trustee, the Guarantee 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 Guarantee Trustee and conforming to the requirements of this
            Guarantee; provided

                                      -11-
<PAGE>
            that in the case of any such certificates or opinions that by any
            provision hereof are specifically required to be furnished to the
            Guarantee Trustee, the Guarantee Trustee shall be under a duty to
            examine the same to determine whether or not they conform to the
            requirements of this Guarantee (but need not confirm or investigate
            the accuracy of any mathematical calculations or other facts stated
            therein);

                 (ii) the Guarantee Trustee shall not be liable for any error of
      judgment made in good faith by a Responsible Officer of the Guarantee
      Trustee, unless it shall be proved that the Guarantee Trustee was
      negligent in ascertaining the pertinent facts upon which such judgment was
      made;

                 (iii) the Guarantee 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 a Majority in liquidation amount of
      the Company Preferred Securities relating to the time, method and place of
      conducting any proceeding for any remedy available to the Guarantee
      Trustee, or the exercise of any trust or power conferred upon the
      Guarantee Trustee under this Guarantee; and

                 (iv) no provision of this Guarantee shall require the Guarantee
      Trustee to expend or risk its own funds or otherwise incur personal
      financial liability in the performance of any of its duties or in the
      exercise of any of its rights or powers, if the Guarantee Trustee shall
      have reasonable grounds for believing that the repayment of such funds or
      liability, or indemnity, satisfactory to the Guarantee Trustee, against
      such expense, risk or liability, is not assured to it under the terms of
      this Guarantee.

            Section 2.11. Certain Rights of Guarantee Trustee.

            (a) Subject to the provisions of Section 2.10:

                 (i) The Guarantee Trustee may conclusively rely, and shall be
      fully protected in acting or refraining from acting upon, any resolution,
      certificate, statement, instrument, opinion, report, notice, request,
      direction, consent, order, bond, debenture, note, other evidence of
      indebtedness or other paper or document (whether in its original or
      facsimile form) believed by it to be genuine and to have been signed, sent
      or presented by the proper party or parties.

                 (ii) Any direction or act of the Guarantor contemplated by this
      Guarantee shall be sufficiently evidenced by an Officers' Certificate.

                 (iii) Whenever, in the administration of this Guarantee, the
      Guarantee Trustee shall deem it desirable that a matter be proved or
      established before taking, suffering or omitting any action hereunder, the
      Guarantee Trustee (unless other evidence is herein specifically
      prescribed) may, in the absence of

                                      -12-
<PAGE>
      bad faith on its part, request and conclusively rely upon an Officers'
      Certificate which, upon receipt of such request, shall be promptly
      delivered by the Guarantor.

                 (iv) The Guarantee Trustee shall have no duty to see to any
      recording, filing or registration of any instrument (or any rerecording,
      refiling or registration thereof).

                 (v) The Guarantee Trustee may, at the expense of the Guarantor,
      consult with counsel of its selection, and the advice or opinion of such
      counsel with respect to legal matters 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 advice
      or opinion. Such counsel may be counsel to the Guarantor or any of its
      Affiliates and may include any of its employees. The Guarantee Trustee
      shall have the right at any time to seek instructions concerning the
      administration of this Guarantee from any court of competent jurisdiction.

                 (vi) The Guarantee Trustee shall be under no obligation to
      exercise any of the rights or powers vested in it by this Guarantee at the
      request or direction of any Holder, unless such Holder shall have provided
      to the Guarantee Trustee such security and indemnity, satisfactory to the
      Guarantee Trustee, against the costs, expenses (including attorneys' fees
      and expenses and the expenses of the Guarantee Trustee's agents, nominees
      or custodians) and liabilities that might be incurred by it in complying
      with such request or direction, including such reasonable advances as may
      be requested by the Guarantee Trustee; provided, that nothing contained in
      this Section 2.11(a)(vi) shall be taken to relieve the Guarantee Trustee,
      upon the occurrence of an Event of Default, of its obligation to exercise
      the rights and powers vested in it by this Guarantee.

                 (vii) The Guarantee Trustee shall not be bound to make any
      investigation into the facts or matters stated in any resolution,
      certificate, statement, instrument, opinion, report, notice, request,
      direction, consent, order, bond, debenture, note, other evidence of
      indebtedness or other paper or document, but the Guarantee Trustee, in its
      discretion, may make such further inquiry or investigation into such facts
      or matters as it may see fit but shall incur no liability or additional
      liability of any kind by reason of such inquiry or investigation.

                 (viii)The Guarantee Trustee may execute any of the trusts or
      powers hereunder or perform any duties hereunder either directly or by or
      through agents, nominees, custodians or attorneys, and the Guarantee
      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.

                 (ix) Any action taken by the Guarantee Trustee or its agents
      hereunder shall bind the Holders of the Company Preferred Securities, and
      the signature of the Guarantee Trustee or its agents alone shall be
      sufficient and

                                      -13-
<PAGE>
      effective to perform any such action. No third party shall be required to
      inquire as to the authority of the Guarantee Trustee to so act or as to
      its compliance with any of the terms and provisions of this Guarantee,
      both of which shall be conclusively evidenced by the Guarantee Trustee or
      its agent taking such action.

                 (x) Whenever in the administration of this Guarantee the
      Guarantee Trustee shall deem it desirable to receive instructions with
      respect to enforcing any remedy or right or taking any other action
      hereunder, the Guarantee Trustee (i) may request written instructions from
      the Holders of a Majority in liquidation amount of the Company Preferred
      Securities, (ii) may refrain from enforcing such remedy or right or taking
      such other action until such written instructions are received and (iii)
      shall be protected in conclusively relying on or acting in accordance with
      such written instructions.

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

            (b) No provision of this Guarantee shall be deemed to impose any
duty or obligation on the Guarantee Trustee to perform any act or acts or
exercise any right, power, duty or obligation conferred or imposed on it in any
jurisdiction in which it shall be illegal, or in which the Guarantee Trustee
shall be unqualified or incompetent in accordance with applicable law, to
perform any such act or acts or to exercise any such right, power, duty or
obligation. No permissive power or authority available to the Guarantee Trustee
shall be construed to be a duty.

            Section 2.12. Not Responsible for Recitals or Issuance of Guarantee.
The recitals contained in this Guarantee shall be taken as the statements of the
Guarantor, and the Guarantee Trustee does not assume any responsibility for
their correctness. The Guarantee Trustee makes no representation as to the

      ($50,000,000), and subject to supervision or examination by federal,
      state, territorial or District of Columbia authority. If such corporation
      publishes reports of condition at least annually, pursuant to law or to
      the requirements of the supervising or examining authority referred to
      above, then, for the purposes of this Section 3.01(a)(ii), the combined
      capital and surplus of such corporation shall be deemed to be its combined
      capital and surplus as set forth in its most recent report of condition so
      published.

            (b) If at any time the Guarantee Trustee shall cease to be eligible
to so act under Section 3.01(a), the Guarantee Trustee shall immediately resign

appointed or removed without cause at any time by the Guarantor except during an
Event of Default.

            (b) The Guarantee Trustee shall not be removed in accordance with

until a Successor Guarantee Trustee shall have been appointed or until its
removal or resignation. The Guarantee Trustee may resign from office (without
need for prior or subsequent accounting) by an instrument in writing executed by
the Guarantee Trustee and delivered to the Guarantor, which resignation shall
not take effect until a Successor Guarantee Trustee has been appointed and has
accepted such appointment by instrument in writing executed by such Successor
Guarantee Trustee and delivered to the Guarantor and the resigning Guarantee
Trustee.

            (d) If no Successor Guarantee Trustee shall have been appointed and

resigning or being removed may petition, at the expense of the Guarantor, any
court of competent jurisdiction for appointment of a Successor Guarantee
Trustee. Such court may thereupon, after

                                      -15-

removal or resignation.

            (a) The Guarantor irrevocably and unconditionally agrees with the
Guarantee Trustee, the Initial Holder and the Holders from time to time of the
Company Preferred Securities, subject to the limitations set forth in this
Guarantee, to pay in full to the Initial Holder and each subsequent Holder of
Company Preferred Securities, whether such rights under this Guarantee are
asserted by the Guarantee Trustee or directly by any such Holder (without
duplication of amounts theretofore paid to the Holders of the Company Preferred
Securities by the Company), regardless of any defense, right of set-off or
counterclaim that the Company may have or assert:

                 (i) on each Mandatory Dividend Payment Date, Dividends on the
      Company Preferred Securities in an amount equal to the Mandatory Dividend
      Payment Amount;

                 (ii) on each other Dividend Payment Date, Dividends (if any) on

      with respect to the Company Preferred Securities called for redemption by

clause of this Section 4.01 without giving effect to this proviso and (B) an
amount calculated as (1) the remaining assets of the Guarantor in the related
bankruptcy or insolvency proceeding after satisfaction of all claims which, as a
matter of law, are prior to those of holders of this Guarantee or any Parity
Guarantee multiplied by (2) a fraction, (x) the numerator of which is the

shall deliver an Officers' Certificate to the Guarantee Trustee within five
Business Days after such Dividend Payment Date or Redemption Date, as
applicable, substantially in the form attached as Exhibit A (the "Guarantor
Certificate").

            Section 4.03. Waiver of Notice and Demand. The Guarantor hereby
waives notice of acceptance of this Guarantee and of any liability to which it
applies or may apply, presentment, demand for payment, any right to require a
proceeding first against the Company or any other Person before proceeding

of redemption and all other notices and demands.

            Section 4.04. Obligations Not Affected. The obligations, covenants,
agreements and duties of the Guarantor under this Guarantee shall in no way be
affected or impaired by reason of the happening from time to time of any of the

      Securities to be performed or observed by the Company;

                 (b) the extension of time for the payment by the Company of all
      or any portion of the Dividends, Redemption Price, Liquidation
      Distribution or any other sums payable under the terms of the Company
      Preferred Securities or the extension of time for the performance of any
      other obligation under, arising out of, or in connection with, the Company
      Preferred Securities; provided that nothing in this Guarantee shall affect
      or impair any valid extension;

                 (c) any failure, omission, delay or lack of diligence on the
      part of the Holders of the Company Preferred Securities to enforce, assert
      or exercise any right, privilege, power or remedy conferred on such
      Holders pursuant to the terms of the Company Preferred Securities, or any
      action on the part of the Company granting indulgence or extension of any
      kind;

                 (d) the voluntary or involuntary liquidation, dissolution, sale
      of any collateral, receivership, insolvency, bankruptcy, assignment for
      the benefit of creditors, reorganization, arrangement, composition or
      readjustment of debt of, or other similar proceedings affecting, the
      Company or any of the assets of the Company;

                 (e) any invalidity of, or defect or deficiency in, the Company
      Preferred Securities;

                 (f) the settlement or compromise of any obligation guaranteed
      hereby or hereby incurred; or

                 (g) any other circumstance whatsoever that might otherwise
      constitute a legal or equitable discharge or defense of a guarantor, it
      being the intent of this Section 4.04 that the obligations of the
      Guarantor hereunder shall be absolute and unconditional under any and all
      circumstances.

            There shall be no obligation of the Holders to give notice to, or
obtain consent of, the Guarantor with respect to the happening of any of the
foregoing.

            Section 4.05. Action Against Guarantor. The Guarantor waives any
right or remedy to require that any action be brought first against the Company
or any other person or entity before proceeding directly against the Guarantor.

            Section 4.06. Independent Obligations. The Guarantor acknowledges
that its obligations hereunder are independent of the obligations of the Company
with respect to the Company Preferred Securities, and that the Guarantor shall
be liable as principal and as debtor hereunder to make Guarantee Payments
pursuant to the terms of this Guarantee notwithstanding the occurrence of any
event referred to in subsections (a) through (g), inclusive, of Section 4.04. It
is further understood that all rights of a Holder of a Company Preferred
Security against the Guarantor under this Guarantee, and all corresponding
obligations of the Guarantor to such Holder, are separate and independent of the
rights and corresponding obligations between the Guarantor and the respective
Holders of the other Company Preferred Securities.

            Section 4.07. Taxes. All payments in respect of the Guarantee
Payments (including interest accrued thereon, if any) by the Guarantor shall be
made without withholding or deduction for or on account of any Relevant Tax,
unless the withholding or deduction of such Relevant Tax is required by law. In
that event, the Guarantor shall pay, as further Guarantee Payments, such
additional amounts as may be necessary in order that the net amounts received by
a Holder (or a third party on its behalf) after such withholding or deduction
will equal the amount which would have been received in respect of the Guarantee
Payments (including interest accrued thereon, if any) in the absence of such
withholding or deduction ("Guarantee Additional Amounts"), except that no such
Guarantee Additional Amounts shall be payable to a Holder (or a third party on
its behalf) with respect to any Guarantee Payments (including interest accrued
thereon, if any), (i) to the extent that such Relevant Tax is imposed or levied
by virtue of such Holder (or the beneficial owner of Company Preferred
Securities to which such Guarantee Payments relate) (other than the Trust)
having some connection with the Relevant Jurisdiction, other than being a Holder
of Company Preferred Securities (or beneficial owner of Company Preferred
Securities) or (ii) to the extent that such the Relevant Tax is imposed or
levied by virtue of such Holder (or beneficial owner) (other than the Trust) not
having made a declaration of non-residence in, or other lack of connection with,
the Relevant Jurisdiction or any similar claim for exemption, if the Guarantor
or its agent has provided the beneficial owner of such Company Preferred
Securities or its nominee with at least 60 days' prior written notice of any
opportunity to make such a declaration or claim.

            Section 4.08. Rights Not Separately Transferable. This Guarantee is
a guarantee for the benefit of each Holder from time to time of Company
Preferred Securities with respect to each Company Preferred Security held by
such Holder. Upon transfer of any Company Preferred Securities to a third party,
a Holder thereof shall no longer have any rights hereunder with respect to such
Company Preferred Securities. The rights under this Guarantee with respect to a
Company Preferred Security are not separately transferable from such Company
Preferred Security. The Initial Holder, by its execution of this Guarantee,
hereby accepts the rights under this Guarantee as initial purchaser and acquirer
of the Company Preferred Securities with the understanding that such rights
shall be transferred by operation of law to any subsequent Holder acquiring a
Company Preferred Security from the Initial Holder or from a subsequent Holder
of Company Preferred Securities.

<PAGE>
            (a) The Guarantor, for so long as any Company Preferred Securities
remain outstanding, shall not issue any preferred or preference shares ranking
senior on liquidation to its obligations under this Guarantee or give any
guarantee in respect of any preferred securities or preferred or preference
shares issued by any of its subsidiaries if such guarantee would rank senior to
this Guarantee, unless this Guarantee is amended to give the Holders of the
Company Preferred Securities such rights and entitlements as are contained in or
attached to such other guarantee so that this Guarantee ranks pari passu with
such guarantee and pari passu on liquidation with any declared dividend or
declared liquidation payments of such preferred or preference shares.

            (b) The Guarantor shall pay all amounts required to be paid pursuant
to this Guarantee in respect of any Dividends on the Company Preferred
Securities payable in respect of the most recent Dividend Period prior to any
dividend or other payment (except dividends in the form of the Ordinary Shares)
upon the Ordinary Shares.

            (c) The Guarantor, for so long as any Trust Preferred Securities or
Company Preferred Securities remain outstanding, shall not (i) issue any
liquidation preference participation rights (not being capital stock) ranking
senior to or pari passu with the right to liquidation payments under its Parity
Preferred Shares, (ii) create, incur or permit to exist any debt junior to its
obligations under this Guarantee or (iii) create, incur or permit to exist any
debt that ranks pari passu with this Guarantee unless such debt contains a
provision substantially similar to proviso contained in Section 4.01.

            (d) The Guarantor, for so long as any Trust Preferred Securities or
Company Preferred Securities remain outstanding, shall (i) maintain, or shall
cause any one or more Qualified Subsidiaries (each, a "Potential
Securityholder") to maintain, 100% ownership of the Company Common Securities.
The Guarantor may transfer or permit the transfer of the Company Common
Securities from one Potential Securityholder to another Potential
Securityholder; provided that prior to such transfer it has received an opinion
of a nationally recognized U.S. law firm experienced in such matters to the
effect that (A) the Company will continue to be treated as a partnership for
United States federal income tax purposes and such transfer will not cause the
Company to be classified as an association or publicly traded partnership
taxable as a corporation for United States federal income tax purposes, (B) such
transfer will not cause the Company or the Trust to be required to register
under the Investment Company Act and (C) such transfer will not adversely affect
the limited liability of the Holders of the Company Preferred Securities.

            (e) The Guarantor, for so long as any Trust Preferred Securities or
Company Preferred Securities remain outstanding, (i) shall use its commercially
reasonable efforts to ensure that the Company will not be an association or a
publicly traded partnership taxable as a corporation for United States federal
income tax purposes, (ii) shall cause the Company to remain a limited liability
company and not to voluntarily dissolve, wind up, liquidate or be terminated,
except as permitted by the LLC Agreement and (iii) shall use its commercially
reasonable efforts to ensure that the Trust will not be classified as other than
a grantor trust for United States federal income tax purposes.

                                      -20-
<PAGE>
            (f) The Guarantor, for so long as any of the Company Preferred
Securities are outstanding, shall, to the fullest extent permitted by law, not
permit, or take any action to cause, the dissolution, liquidation, termination
or winding up of the Company, unless the Guarantor is itself in liquidation.

            (g) If the Company Preferred Securities are distributed to Holders
of Trust Preferred Securities in connection with the involuntary or voluntary
dissolution, winding-up or liquidation of the Trust, the Guarantor shall use its
commercially reasonable efforts to cause the Company Preferred Securities to be
listed on the Luxembourg Stock Exchange or on such other national securities
exchange or similar organization as the Trust Preferred Securities are then
listed or quoted on.

            Section 5.02. Ranking.

            (a) The Guarantee will constitute a general and unsecured obligation
of UBS AG and, in liquidation of UBS AG, will rank, both as to payment and in
liquidation:

                 (i) subordinate and junior to all deposits and other
      liabilities of the Guarantor (including those in respect of bonds, notes
      and debentures that do not expressly rank pari passu with the obligations
      of the Guarantor under this Agreement); and

                 (ii) senior to the Ordinary Shares and any other securities of
      the Guarantor expressed to rank junior to the most senior preference
      shares of the Guarantor (if any) from time to time outstanding.

The foregoing liabilities that rank senior to the Guarantee are collectively
called "UBS AG Senior Liabilities".

            (b) Payments under this Guarantee (other than payments upon a
winding-up or dissolution, by bankruptcy or otherwise, in Switzerland of the
Guarantor) are conditional upon the Guarantor not being in default in the
payment of UBS AG Senior Liabilities and being Solvent at the time of payment. A
report as to the insolvency of the Guarantor by two persons, each being a
managing director, director or other authorized officer or agent of the
Guarantor or employees of the independent accountants of the Guarantor will, in
the absence of manifest error be treated and accepted by the Guarantor, the
holders of Company Preferred Securities and all other interested parties as
correct and sufficient evidence thereof.

            Section 6.01. Termination. This Guarantee shall terminate upon, and
be of no further force and effect from the earlier of (i) full payment of the
Redemption Price of all Company Preferred Securities or purchase and
cancellation of all Company Preferred Securities or (ii) upon full payment of
the Liquidation Distribution, plus Additional Amounts thereon, if any, as
payable upon liquidation of the Company. Notwithstanding the foregoing, this
Guarantee will continue to be effective or will be reinstated, as the case may
be, if at any time any Holder of Company Preferred Securities must restore
payment of any sums paid under the Company Preferred Securities or under this
Guarantee for any reason whatsoever.

                                 INDEMNIFICATION

            Section 7.01. Exculpation.

            (a) No Indemnified Person shall be liable, responsible or
accountable in damages or otherwise to the Guarantor or any Covered Person for
any loss, liability, expense, damage or claim incurred by reason of any act or
omission performed or omitted by such Indemnified Person in good faith in
accordance with this Guarantee and in a manner that such Indemnified Person
reasonably believed to be within the scope of the authority conferred on such
Indemnified Person by this Guarantee or by law, except that an Indemnified
Person shall be liable for any such loss, liability, expense, damage or claim
incurred by reason of such Indemnified Person's negligence or willful misconduct
with respect to such acts or omissions.

            (b) An Indemnified Person shall be fully protected in relying in
good faith upon the records of the Guarantor and upon such information,
opinions, reports or statements presented to the Guarantor by any Person as to
matters the Indemnified Person reasonably believes are within such other
Person's professional or expert competence and who has been selected with
reasonable care by or on behalf of the Guarantor, including information,
opinions, reports or statements as to the value and amount of the assets,
liabilities, profits, losses, or any other facts pertinent to the existence and
amount of assets from which Dividends to Holders of Company Preferred Securities
might properly be paid.

            Section 7.02. Indemnification. The Guarantor agrees to indemnify
each Indemnified Person for, and to hold each Indemnified Person harmless
against, any and all loss, liability, damage, claim or expense (including taxes
other than taxes based on the income of any such Indemnified Person) incurred
without negligence or bad faith on its

                                      -22-
<PAGE>
part, arising out of or in connection with the acceptance or administration of
the trust or trusts hereunder, including the costs and expenses (including
reasonable legal fees and expenses) of defending itself against, or
investigating, any claim or liability in connection with the exercise or
performance of any of its powers or duties hereunder. The obligation to
indemnify as set forth in this Section 7.02 shall survive the termination of
this Guarantee or the earlier resignation or removal of the Guarantee Trustee.

                                  MISCELLANEOUS

            Section 8.01. Successors and Assigns. All guarantees and agreements
contained in this Guarantee shall bind the successors, assigns, receivers,

the Holders of the Company Preferred Securities then outstanding.

            Section 8.02. Amendments. Except for those changes (i) required
under Section 5.01(a) above, which may be made unilaterally by the Guarantor
without the consent of the Holders of the Company Preferred Securities, or (ii)
provided for in the two penultimate sentences of this paragraph, this Guarantee
may be modified by the Guarantor and the Guarantee Trustee only with the prior
approval of the Holders of not less than 662/3% in liquidation amount of the
Company Preferred Securities (excluding any Company Preferred Securities held by
the Guarantor or any of its Affiliates, other than Company Preferred Securities
purchased or acquired by the Guarantor or its Affiliates in connection with

of its Affiliates in connection with the distribution or trading of or

respect to such pledged securities pursuant to the terms of such pledge). This

extent as may be necessary or desirable; provided that no such amendment made in
reliance upon clause (v) above shall have a material adverse effect on the
rights, preferences or privileges of the Holders of the Company Preferred
Securities. Except as provided in the preceding sentence, Sections 4.01, 4.02,
4.07 and the form of Exhibit A may not be amended without the prior approval of
each Holder of the Company Preferred Securities. Any amendment hereof in
accordance with this Section 8.02 shall be binding on all Holders of Company
Preferred Securities.

            Section 8.03. Judgment Currency Indemnity.

<PAGE>
            (a) If, for the purposes of obtaining judgment in any court, it is
necessary to convert an amount due from the Guarantor under any provision of
this Guarantee to a currency other than U.S. dollars, the parties agree, to the
fullest extent that they may effectively do so, that the rate of exchange used
shall be that at which in accordance with normal banking procedures Wilmington
Trust Company could purchase such other currency with U.S. dollars at its
Wilmington office on the second Business Day preceding the day on which final
judgment is given.

            (b) The obligations of the Guarantor in respect of any amount due to
the Guarantee Trustee or any Holders under this Agreement shall, notwithstanding
any judgment in a currency other than U.S. dollars, be discharged only to the
extent that on the Business Day following receipt by the Guarantee Trustee or
such Holders, as the case may be, of any amount adjudged to be so due in such
other currency the Guarantee Trustee or such Holders, as the case may be, may in
accordance with normal banking procedures purchase U.S. dollars with such other
currency.

            (c) If the amount of U.S. dollars so purchased is less than the
amount originally due to the Guarantee Trustee or such Holders, as the case may
be, in U.S. dollars, the Guarantor agrees, to the fullest extent that it may
effectively do so, as a separate obligation and notwithstanding any such
judgment, to indemnify the Guarantee Trustee or such Holders, as the case may
be, against such loss.

            (d) If the amount of dollars so purchased exceeds the amount
originally due to the Guarantee Trustee or such Holders, as the case may be, in
U.S. dollars, agree to remit any remaining amount to the Guarantor.

            Section 8.04. Assignment of the Guarantor. The Guarantor may not
assign its obligations under the Guarantee, except in the case of a merger or
consolidation where the Guarantor is not the surviving entity, or a sale of
substantially all of its assets, and then only to the entity which is the
survivor of such merger or consolidation or the Purchaser in such sale.

                              OFFICERS' CERTIFICATE

[Date]

            The undersigned, [Robert Mills], Chief Financial Officer -- Americas
and Regional Chief Operating Officer, and [Robert Dinerstein], Senior Managing
Director and Special Counsel, of UBS AG, a bank organized under the laws of
Switzerland, pursuant to Section 4.02 of the Subordinated Guarantee Agreement,
dated as of _______ __, 20- (the "Guarantee"), executed and delivered by
UBS AG, as guarantor, Wilmington Trust Company, in its capacity as trustee
pursuant to the Trust Agreement, and Wilmington Trust Company, as trustee, for
the benefit of the Holders from time to time of the -% Noncumulative
Company Preferred Securities (the "Company Preferred Securities") of UBS
Preferred Funding Company LLC V, do hereby certify as of the date hereof on
behalf of UBS AG as follows (capitalized terms used herein without definitions
have the meanings assigned to them in the Guarantee):

                 1. We have read and are familiar with the provisions of the
      Guarantee (including, without limitation, Section 4.02 thereof) and all
      definitions therein.

                 2. We have reviewed all corporate documents necessary to state
      the facts contained herein and are duly authorized to certify to those
      facts.

                 3. In our opinion, we have made such examination or
      investigation as is necessary to enable us to express an informed opinion
      as to the facts certified herein.

                 4. [Neither] [Either] UBS AG [nor] [or] any of its subsidiaries
      has redeemed, repurchased or otherwise acquired (other than (I) in
      connection with transactions effected by or for the account of customers
      of the Guarantor or any of its subsidiaries or in connection with the
      distribution, trading or market-making in respect of such securities, (II)
      in connection with the satisfaction by the Guarantor or any of its
      subsidiaries of its obligations under any employee benefit plans or
      similar arrangements with or for the benefit of employees, officers,
      directors or consultants, (III) as a result of a reclassification of the
      capital stock of the Guarantor or any of its subsidiaries or the exchange
