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

            Section 2.05. Evidence of Compliance with Conditions Precedent. The
Grantor shall provide to the Trustee evidence of compliance with the conditions
precedent, if any, provided for in this Trust Agreement that relate to any of

certificate or opinion required to be given by an officer pursuant to Section
314(c)(1) of the Trust Indenture Act may be given in the form of an Officers'
Certificate.

            Section 2.06. Defaults; Waiver.

            (a) The Holders of a majority in liquidation amount of the Trust
Preferred Securities may, by vote, on behalf of the Holders of all of the Trust
Preferred Securities, waive any past default in respect of the Trust Preferred
Securities and its consequences; provided that, if the underlying event of
default is also a default in respect of the Company Preferred Securities and:

                  (i) is not waivable under the LLC Agreement, the default under
      this Trust Agreement shall also not be waivable; or

                  (ii) requires the consent or vote of the holders of more than
      50% of the aggregate liquidation preference of the Company Preferred
      Securities to be waived under the LLC Agreement (a "Super Majority"), the
      default under this Trust Agreement may only be waived by the vote of the
      Holders of at least the relevant Super Majority in liquidation amount of
      the Trust Preferred Securities.

            The foregoing provisions of this Section 2.06(a) shall be in lieu of
Section 316(a)(1)(B) of the Trust Indenture Act and such Section 316(a)(1)(B) of
the Trust Indenture Act is hereby expressly excluded from this Trust Agreement
and the Trust Preferred Securities, as permitted by the Trust Indenture Act.
Upon such waiver, any such default shall cease to exist, and any default with
respect to the Trust Preferred Securities arising therefrom shall be deemed to
have been cured, for every purpose of this Trust Agreement, but no such waiver
shall extend to any subsequent or other default with respect to the Trust
Preferred Securities or impair any right consequent thereon.

            (b) A waiver of a default under the LLC Agreement by the Trustee at
the direction of the Holders of the Trust Preferred Securities constitutes a
waiver of the corresponding default under this Trust Agreement. The foregoing
provisions of this Section 2.06(b) shall be in lieu of Section 316(a)(1)(B) of
the Trust Indenture Act and such Section

                                      -6-

316(a)(1)(B) of the Trust Indenture Act is hereby expressly excluded from this
Trust Agreement and the Trust Preferred Securities, as permitted by the Trust
Indenture Act.

             Section 2.07. Trust Enforcement Event; Notice. The Trustee shall,
within 90 days after the occurrence of a default with respect to the Trust
Preferred Securities, transmit by mail, first class postage prepaid, to the
Holders of the Trust Preferred Securities, notices of all defaults with respect
to the Trust Preferred Securities actually known to the Trustee, unless such
defaults shall have been cured before the giving of such notice; provided that,
the Trustee shall be protected in withholding such notice if and so long as the
Trustee in good faith determines that the withholding of such notice is in the
interests of the Holders of the Trust Preferred Securities.

hereby constitute a statutory trust under the Statutory Trust Act and that this
Agreement constitute the governing instrument of the Trust. The Trust exists for

for any other action of any Person, including the Trustee or any other Holder,
each Holder shall be entitled to enforce, in the name of the Trust, the rights
of the Trust under the Company Preferred Securities and the Subordinated
Guarantee represented by the Trust Preferred Securities held by such Holder. Any
recovery on such an enforcement action shall belong solely to such Holder who
brought the action, not to the Trust, the Trustee or any other Holder
individually or to the Holders as a group. The Trustee shall have the power and
authority (subject to the Trustee's rights, privileges and protections in
Section 6.02 and elsewhere herein) to enforce any of the Trust's rights in
respect of the Company Preferred Securities which are not enforced by any
Holder. Subject to Section 7.02, the Trust shall be irrevocable.

            (b) The Trustee hereby acknowledges receipt of one or more Company
Preferred Securities Certificates representing Company Preferred Securities
having an aggregate liquidation preference of $- registered in the name of the
Trust, and its acceptance on behalf of the Trust of the Company Preferred
Securities, and declares that the Trust shall hold the Company Preferred
Securities for the benefit of the Holders of the Trust Preferred Securities.

accordance with the Section 8.05, as shall be reasonably necessary (and for so
long as may be reasonably necessary) to enable such co-trustee or agents to

appropriate insertions, modifications and omissions, as hereinafter provided.

            (b) The Trust Preferred Securities shall be issued in denominations
of $[1,000][25] liquidation amount and whole-number multiples of $[1,000][25].
All Trust Preferred Securities shall be dated the date of their execution or

incorporated in the text thereof such legends or recitals or changes not
inconsistent with the provisions of this Trust Agreement as may be required by
the Trustee or any applicable law or regulation or the rules and regulations of
any securities exchange upon which the Trust Preferred Securities may be listed
or to conform with any usage with respect thereto.

            (d) Title to any Trust Preferred Security that is properly endorsed
or accompanied by a properly executed instrument of transfer or endorsement
shall be transferable by delivery with the same effect as in the case of a
negotiable instrument; provided, however, that until the transfer shall be
registered on the Register as provided in Section 4.03, the Trust, the Trustee,
the Registrar and the Grantor may, notwithstanding any notice to the contrary,
treat the Holder thereof at such time as the absolute owner thereof for the
purpose of determining the Person entitled to distributions or to any notice
provided for in this Trust Agreement and for all other purposes.

            (e) Trust Preferred Securities shall be executed by the Trustee by
the manual signature of a duly authorized signatory of the Trustee, provided,
however, that such signature may be a facsimile if a Registrar (other than the
Trustee) shall have countersigned the Trust Preferred Security by manual
signature of a duly authorized signatory of the Registrar. No Trust Preferred
Security shall be entitled to any benefit under this Trust Agreement or be valid
or obligatory for any purpose unless it shall have been executed as provided in
the preceding sentence. The Registrar shall record on the Register each Trust
Preferred Securities executed as provided above and delivered as hereinafter
provided. Trust Preferred Securities bearing the signatures of individuals who
were, at the time when such signatures shall have been affixed, authorized to
sign on behalf of the Trustee 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 Trust Preferred Securities or did not hold such offices at the
date of delivery of such Trust Preferred Securities.

            Section 4.02. Issuance of Trust Preferred Securities.

            (a) The Trustee having received on behalf of the Trust one or more
Company Preferred Securities Certificates representing Company Preferred
Securities with an aggregate liquidation preference of $- and having

            (b) Beneficial interests in the Trust Preferred Securities will be
evidenced by, and transfers thereof will be effected only through, records
maintained by the Clearing Agency Participants. Unless and until Definitive
Trust Preferred Securities Certificates have been issued to the Owners pursuant
to Section 4.03(c):

                  (i) the provisions of this Section 4.02(b) shall be in full
      force and effect;

                  (ii) the Trust and the Trustee shall be entitled to deal with
      the Clearing Agency for all purposes of this Trust Agreement (including
      the payment of Dividends on the Global Certificate and receiving
      approvals, votes or consents hereunder) as the Holder of the Trust
      Preferred Securities and the sole Holder of the Global Certificate, and
      shall have no obligation to the Owners;

                  (iii) to the extent that the provisions of this Section
      4.02(b) conflict with any other provisions of this Trust Agreement, the
      provisions of this Section 4.02(b) shall control; and

                  (iv) the rights of the Owners shall be exercised only through
      the Clearing Agencies and shall be limited to those established by law and
      agreements between such Owners and the relevant Clearing Agency and/or the
      Clearing Agency Participants, and the Clearing Agency shall receive and
      transmit payments of Dividends on the Global Certificate to such Clearing
      Agency Participants. The Clearing Agency will make book-entry transfers
      among the Clearing Agency Participants; provided, that solely for the
      purposes of determining whether the Holders of the requisite amount of
      Trust Preferred Securities have voted on any matter provided for in this
      Trust Agreement, so long as Definitive Trust Preferred Securities
      Certificates have not been issued to the Owners pursuant to Section
      4.03(c), the Trustee may conclusively rely on, and shall be fully
      protected in relying on, any written instrument (including a proxy)
      delivered to the Trustee by any Clearing Agency setting forth the Owners'
      votes or assigning the right to vote on any matter to any other Persons
      either in whole or in part.

            (c) Notices to Clearing Agency. Whenever a notice or other
communication to the Holders is required under this Trust Agreement, unless and
until Definitive Trust Preferred Securities Certificates shall have been issued
to the Owners pursuant to Section 4.03(c), the Trustee shall give all such
notices and communications specified herein to be given to the Holders to the
Clearing Agency, and shall have no notice obligations to the Owners except that
for as long as the Trust Preferred Securities are listed on the [insert
applicable stock exchange], all notices regarding the Trust Preferred Securities
shall be published in English in one leading daily newspaper with circulation in
[insert location/country of applicable stock exchange] (which is expected to be
the [insert name of newspaper]) as long as such publication is required under
the rules of the [insert applicable stock exchange].

            (d) Appointment of Successor Clearing Agency. If any Clearing Agency
elects to discontinue its services as securities depositary with respect to the
Trust Preferred

                                      -10-
<PAGE>
Securities, the Grantor and the Trust shall use their best efforts to appoint a
successor Clearing Agency with respect to the Trust Preferred Securities.

            Section 4.03. Registration, Transfer and Exchange of Trust Preferred
Securities.

            (a) The Trustee shall cause a Register (the "Register") to be kept
at the office of the Registrar in which, subject to such reasonable regulations
as the Trustee and the Registrar may prescribe, the Trustee shall provide for
the registration of Trust Preferred Securities and of transfers and exchanges of
Trust Preferred Securities as herein provided. In the absence of appointing a
third party, the Trustee shall serve as the Registrar. The Grantor may remove
the Registrar and, upon removal or resignation of the Registrar, appoint a
successor Registrar. Subject to the terms and conditions of this Trust
Agreement, the Registrar shall register the transfers on the Register from time
to time of Trust Preferred Securities upon any surrender thereof by the Holder
in person or by a duly authorized attorney, properly endorsed or accompanied by
a properly executed instrument of transfer or endorsement, together with
evidence of the payment of any transfer taxes as may be required by law. Upon
such surrender, the Trustee shall execute a new Trust Preferred Security
representing the same corresponding amount of Company Preferred Securities in
accordance with Section 4.01(e) and deliver the same to or upon the order of the
Person entitled thereto.

            (b) At the option of a Holder, Trust Preferred Securities may be
exchanged for other Trust Preferred Securities representing the same
corresponding amount of Company Preferred Securities. Upon surrender of a Trust
Preferred Security at the office of the Registrar or such other office as the
Trustee may designate for the purpose of effecting an exchange of Trust
Preferred Securities, subject to the conditions to transfer set forth in this
Trust Agreement, the Trustee shall execute and deliver a new Trust Preferred
Security representing the same corresponding amount of Company Preferred
Securities as the Trust Preferred Security surrendered.

            As a condition precedent to the registration of the transfer or
exchange of any Trust Preferred Security, the Registrar may require (i)
production of proof satisfactory to it as to the identity and genuineness of any
signature; (ii) compliance with such regulations, if any, as the Trustee or the
Registrar may establish not inconsistent with the provisions of this Trust
Agreement; and (iii) such other information as the Registrar may reasonably
request.

            No Holder may require the transfer of any Trust Preferred Security
to be registered during the period of fifteen days ending on the due date for
any payment of principal on the Trust Preferred Securities. The Trust shall not
be required to register, or cause others to register, the transfer of Trust
Preferred Securities after such Trust Preferred Securities have been called for
redemption.

            Registration of transfers of Trust Preferred Securities, including
Trust Preferred Securities Certificates, shall be made without change by the
Trust, but the transferor must pay any tax or governmental charge that may be
imposed in relation to the transfer, together with any indemnity that the Trust
or the Bank or the Transfer Agent may require.

                                      -11-
<PAGE>
            (c) The Global Certificate is exchangeable for Definitive Trust
Preferred Security Certificates in registered form if DTC: (i) notifies the
Trust that it is unwilling or unable to continue as depositary for the Global
Certificate and the Trust does not appoint a successor depositary or (ii) has
ceased to be a clearing agency registered under the Securities Exchange Act of
1934. Upon surrender of the Global Certificates by the Clearing Agency,
accompanied by registration instructions, the Grantor will cause to be prepared
for delivery to the Owners the Definitive Trust Preferred Certificates in
accordance with instructions of the Clearing Agency.

            Definitive Trust Preferred Securities Certificates may be
transferred in any whole-number multiples of $[1,000][25] by surrendering the
Definitive Trust Preferred Securities Certificates, together with the form of
transfer endorsed on it, duly completed and executed, at the specified office of
the Transfer Agent. The initial Transfer Agent shall be Wilmington Trust
Company. As long as the Trust Preferred Securities are listed on the [insert
applicable stock exchange], the Trust shall also maintain a Transfer Agent in
[insert location/country of applicable stock exchange]. The initial [insert
location/country of applicable stock exchange] Transfer Agent shall be [Name of
Transfer Agent]. If only part of a Definitive Trust Preferred Securities
Certificate is transferred, a new Definitive Trust Preferred Securities
Certificate representing the securities not transferred shall be issued to the
transferor within three business days after the Transfer Agent receives the
certificate. The new Definitive Trust Preferred Securities Certificate
representing the Trust Preferred Securities that were not transferred shall be
delivered to the transferor by uninsured mail at the risk of the transferor, to
the address of the transferor that appears in the Register. The new Definitive
Trust Preferred Securities Certificate representing the Trust Preferred
Securities that were transferred shall be sent to the transferee within three
business days after the Trustee receives the surrendered Definitive Trust
Preferred Securities Certificate by uninsured mail at the risk of the Holder
entitled to the Definitive Trust Preferred Securities Certificate, to the
address specified on the form of transfer.

            All transfers of Definitive Trust Preferred Securities Certificates
and entries shall be made as provided in the Registrar and Transfer Agency
Agreement, among the Trust and the Registrar and Transfer Agents, relating to
the Trust Preferred Securities.

            Section 4.04. Lost or Stolen Trust Preferred Securities, Etc. If (i)
any mutilated Trust Preferred Security shall be surrendered to the Registrar, or
if the Registrar shall receive evidence to its satisfaction of the destruction,
loss or theft of any Trust Preferred Security, and (ii) there shall be delivered
to the Registrar and the Grantor such security or indemnity as may be required
by them to hold each of them harmless, then in the absence of notice that such
Trust Preferred Security shall have been acquired by a bona fide purchaser or,
as applicable, any protected purchaser, the Grantor shall sign and make
available for delivery, in exchange for or in lieu of any mutilated, destroyed,
lost or stolen Trust Preferred Security, a new Trust Preferred Security
representing the same amount of corresponding Company Preferred Securities. In
connection with the issuance of any new Trust Preferred Security, the Grantor
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
Trust Preferred Security issued pursuant to this Section shall constitute
conclusive evidence of a Trust Preferred Security corresponding to that

                                      -12-
<PAGE>
evidenced by the lost, stolen or destroyed Trust Preferred Security, as if
originally issued, whether or not the lost, stolen or destroyed Trust Preferred
Security shall be found at any time.

            Section 4.05. Cancellation and Destruction of Surrendered
Certificates. All Trust Preferred Securities surrendered to the Trustee shall be
canceled by the Trustee. Except as prohibited by applicable law or regulation,
the Trustee may destroy such canceled Trust Preferred Securities or otherwise
dispose of them in accordance with its usual practices.

            Section 4.06. Surrender of Trust Preferred Securities and Withdrawal
of Company Preferred Securities. Any Person who is the beneficial owner (an
"Owner") of the Trust Preferred Securities represented by the Global
Certificates held by DTC or a successor clearing agency (the "Clearing Agency")
or, if a participant in the Clearing Agency is not the Owner, then as reflected
in the records of a Person maintaining an account with such Clearing Agency
(directly or indirectly), in accordance with the rules of such Clearing Agency,
may withdraw all, but not less than all, of the Company Preferred Securities
represented by such Trust Preferred Securities by providing a written notice to
the Trustee, with evidence of beneficial ownership in form satisfactory to the
Trustee, and providing to the Grantor such documents or information as the
Grantor may request for tax reporting purposes, at the Corporate Office or at
such other office as the Trustee may designate for such withdrawals, all in form
satisfactory to the Trustee, in its sole discretion. The Owner's notice shall
also be deemed to be such Owner's agreement to be subject to the terms of the
LLC Agreement applicable to the rights of holders of the Company Preferred
Securities.

            Within a reasonable period after such a request has been properly
made, the Trustee shall instruct DTC to reduce the Trust Preferred Securities
represented by the Global Certificate by the corresponding amount of the Company
Preferred Securities to be so withdrawn by the withdrawing Owner. The Grantor
shall issue to the withdrawing Owner a Company Preferred Securities Certificate
representing the amount of the Company Preferred Securities so withdrawn, and
the Trustee, on behalf of the Trust, shall instruct DTC to reduce the amount of
Trust Preferred Securities represented by the Global Certificate held by DTC by
such amount.

            Any Owner who wishes to withdraw the Company Preferred Securities in
accordance with this Section 4.06 shall be required to provide the Grantor with
a completed Internal Revenue Service Form W-9 or W-8, as appropriate, and/or
such other documents or information as are requested by the Grantor for tax
reporting purposes and thereafter shall be admitted to the Grantor as a member
of the Grantor upon such Owner's receipt of a Company Preferred Securities
Certificate registered in such Owner's name.

            The Trustee shall deliver the appropriate number of Company
Preferred Securities Certificates in exchange for the Trust Preferred Securities
surrendered in accordance with this Section 4.06 to the Owner at the Corporate
Office, except that, at the request, risk and expense of the Owner and for the
account of the Owner, such delivery may be made at such other place as may be
designated by such Owner. The Trustee shall only deliver such Company Preferred
Securities Certificates upon payment by such Owner to the Trustee of all taxes
and other governmental charges and any fees (including the fees and expenses of
the Trustee and its

                                      -13-
<PAGE>
counsel) payable in connection with such delivery and the transfer of such
Company Preferred Securities Certificates.

            Notwithstanding anything in this Section 4.06 to the contrary, if
the Company Preferred Securities exchangeable for Trust Preferred Securities
have been called for redemption in accordance with the LLC Agreement, no Owner
of such Trust Preferred Securities may withdraw any or all of the Company
Preferred Securities represented by such Trust Preferred Securities.

            Section 4.07. Redeposit of Company Preferred Securities. Any Holder
of Company Preferred Securities may redeposit withdrawn Company Preferred
Securities by delivering to the Trustee the Company Preferred Securities
Certificate for the Company Preferred Securities to be deposited, which are (i)
if required by the Trustee, properly endorsed or accompanied by a properly
executed instrument of transfer or endorsement in form satisfactory to the
Trustee and in compliance with the terms of the LLC Agreement and (ii)
accompanied by all such certifications as may be required by the Trustee in its
sole discretion and in accordance with the provisions of this Trust Agreement.
Within a reasonable period after such deposit is properly made, the Trustee
shall instruct DTC to increase the amount of Trust Preferred Securities
represented by the Global Certificate held by DTC by an amount equal to the
Company Preferred Securities so deposited. The Trustee shall only accept the
redeposit of such Company Preferred Securities upon payment by such Holder of
the Company Preferred Securities to the Trustee of all taxes and other
governmental charges and any fees and expenses (including the fees and expenses
of the Trustee and its counsel) payable in connection with such deposit and the
transfer of the deposited Company Preferred Securities.

            If required by the Trustee, Company Preferred Securities
Certificates presented for redeposit at any time shall also be accompanied by an
agreement or assignment, or other instrument satisfactory to the Trustee, that
shall provide for the prompt transfer to the Trustee or its nominee of any
distribution or other right that any Person in whose name the Company Preferred
Securities Certificates are registered may thereafter receive upon or in respect
of such deposited Company Preferred Securities, or in lieu thereof such
agreement of indemnity or other agreement as shall be satisfactory to the
Trustee.

            Section 4.08. Filing Proofs, Certificates and Other Information. Any
Person presenting Company Preferred Securities Certificates for redeposit in
accordance with Section 4.06 may be required from time to time to file such
proof of residence or other information, to execute such certificates and to
make such representations and warranties as the Trustee may reasonably deem
necessary or proper.

            Section 5.01. Periodic Distributions. Whenever (and to the extent)
the Trust receives any cash payments representing a Dividend or redemption
payment on the Company Preferred Securities, or payments from the Bank pursuant
to the Subordinated Guarantee in respect of such Dividend or redemption payment,
the Trustee acting directly or through any Paying Agent shall distribute such
amounts to Holders of the Trust Preferred Securities on the record date fixed
pursuant to Section 5.04, in proportion to the respective liquidation amount of
Trust Preferred Securities held by such Holders.

            Section 5.02. Redemptions of Company Preferred Securities. The Trust
Preferred Securities shall be redeemed only upon redemption of the Company
Preferred Securities.

            If the Grantor redeems the Company Preferred Securities in
accordance with the LLC Agreement, then the Grantor shall give the Trustee at
least 30 days' prior notice before doing so. The Trustee shall mail the notice
of the redemption not less than 25 days prior to the date fixed for redemption
(the "Redemption Date") of the Company Preferred Securities to the Holders of
the Trust Preferred Securities as provided under Section 8.04. No defect in the
notice of redemption or in the mailing or delivery thereof shall affect the
validity of the redemption proceedings. The Grantor shall provide the Trustee
with such notice, and each such notice shall state: (i) the Redemption Date,
(ii) the redemption price at which the Trust Preferred Securities and the
Company Preferred Securities are to be redeemed, (iii) that all outstanding
Trust Preferred Securities are to be redeemed or, in the case of a redemption of
fewer than all outstanding Trust Preferred Securities in connection with a
partial redemption of the Company Preferred Securities, the amount of such Trust
Preferred Securities to be so redeemed and (iv) the place or places where Trust
Preferred Securities to be redeemed are to be surrendered for redemption.

            If only some of the outstanding Trust Preferred Securities are to be
redeemed, the Trust Preferred Securities to be redeemed shall be selected in
accordance with DTC's procedures. If the Trust Preferred Securities do not
remain registered in the name of DTC or its nominee and only some of the
outstanding Trust Preferred Securities are to be redeemed, the Trust Preferred
Securities shall be redeemed proportionally or selected for redemption pursuant
to the rules of any securities exchange on which the Trust Preferred Securities
are listed at that time. The Grantor shall promptly notify the Registrar and
Transfer Agent, in writing, of the Trust Preferred Securities selected for
redemption.

            The Grantor agrees that if a partial redemption of the Company
Preferred Securities would result in a delisting of the Trust Preferred
Securities from any securities exchange on which the Trust Preferred Securities
are then listed, the Grantor shall only redeem the Company Preferred Securities
in whole.

            On the date of redemption of the Company Preferred Securities, so
long as the Company or the Bank has deposited with Wilmington Trust Company, the
Paying Agent, on behalf of the Trust the aggregate amount payable upon
redemption of all the Company Preferred Securities held by the Trust to be
redeemed, the Paying Agent on behalf of the Trust shall irrevocably deposit with
DTC funds sufficient to pay the redemption price and give DTC

                                      -15-
<PAGE>
irrevocable instructions to pay the redemption price to the Holders of the Trust
Preferred Securities to be redeemed.

            Once the Paying Agent has received this deposit, all rights of the
Holders of the Trust Preferred Securities called for redemption shall end,
except their right to receive the redemption price, without interest. If any
date fixed for redemption of the Trust Preferred Securities is not a Business
Day, then the redemption price shall instead be paid on the next Business Day,
except that if that Business Day falls in the next calendar year, the redemption
price shall be paid on the preceding Business Day. No interest or other payment
shall be due as a result of any such adjustment.

            Section 5.03. Distributions in Liquidation of Grantor. Upon receipt
by the Trust of any Liquidation Preference from the Grantor upon the liquidation
of the Grantor, after satisfaction of creditors of the Trust as required by
applicable law, the Trust shall distribute the same to the Holders of the Trust
Preferred Securities on the record date fixed pursuant to Section 4.04, in
proportion to the respective Liquidation Preference of the Company Preferred
Securities which were exchangeable for the Trust Preferred Securities held by
such Holders.

            Section 5.04. Fixing of Record Date for Holders of the Trust
Preferred Securities. Each distribution on the Trust Preferred Securities in
respect of Dividends on the Company Preferred Securities (each a "Regular
Distribution") shall be payable to the Holders as they appear on the Register on
the corresponding record date. The record date for Regular Distributions is the
fifteenth calendar day prior to the relevant distribution date. Whenever any
other distribution shall become payable, or whenever the Trustee shall receive
notice of any meeting at which Holders of the Company Preferred Securities are
entitled to vote or of which Holders of the Company Preferred Securities are
entitled to notice, the Trustee shall in each such instance fix a record date
(which shall be the same date as the record date fixed by the Grantor with
respect to the Company Preferred Securities, of which the Grantor shall promptly
inform the Trustee) for the determination of the Holders of the Trust Preferred
Securities who shall be entitled (i) to receive such distribution, or (ii) to
receive notice of, and to give instructions for the exercise of voting rights
at, any such meeting.

            Section 5.05. Payment of Distributions. The Trust shall maintain a
Paying Agent with respect to the Trust Preferred Securities, which shall
initially be Wilmington Trust Company. The Paying Agent shall be permitted to
resign as Paying Agent upon 30 days' written notice to the Trustee. If
Wilmington Trust Company resigns as Paying Agent, the Trustee shall appoint
another bank or trust company to act as Paying Agent. As long as the Trust
Preferred Securities are listed on the [insert applicable stock exchange], the
Trust shall also maintain a Paying Agent in [insert location/country of
applicable stock exchange]. The initial [insert location/country of applicable
stock exchange]Paying Agent shall be [insert name of Paying Agent].

            As long as the Trust Preferred Securities are in book-entry form,
payments on the Trust Preferred Securities shall be made to DTC, which shall
credit the relevant accounts at DTC on the scheduled payment dates. The payments
shall be distributed to participants, indirect

                                      -16-
<PAGE>
participants and beneficial owners of the Trust Preferred Securities in
accordance with DTC's procedures.

            If Definitive Trust Preferred Securities Certificates are issued as
described in Section 4.03(c), payments on the Trust Preferred Securities shall
be made by check mailed to the address of the Holder entitled to receive the
payment, as such address appears in the Register.

            Payments of the redemption price of, and distributions in
liquidation on, Trust Preferred Securities shall be made upon surrender of such
Trust Preferred Securities at the office of the Paying Agent. The Grantor shall
pay Dividends on, the redemption price of, and Liquidation Preferences on, the
Company Preferred Securities directly to the Paying Agent for distribution to
the Holders of the Trust Preferred Securities in accordance with the terms of
this Trust Agreement and the paying agency agreement as then in effect with the
Paying Agent.

            If any distributions on the Trust Preferred Securities would be
payable on a day that is not a Business Day, that distribution shall instead be
made on the next Business Day. No interest or other payment shall be due as a
result of any such delay.

            Section 5.06. Voting Rights. If at any time, the holders of Company
Preferred Securities are entitled to vote under the LLC Agreement, the Trustee
shall: (i) notify the Holders of the Trust Preferred Securities of such right,
(ii) request specific direction from each Holder as to the vote with respect to
the Company Preferred Securities represented by such Holder's Trust Preferred
Securities, and (iii) vote the relevant Company Preferred Securities only in
accordance with such specific direction.

            Upon receiving notice of any meeting at which the holders of Company
Preferred Securities are entitled to vote, the Trustee shall, as soon as
practicable, mail to the Holders of the Trust Preferred Securities a notice as
provided under Section 8.04. The Company shall provide the form of notice to the
Trustee to be forwarded to the Holders of the Trust Preferred Securities. The
notice shall contain: (i) all the information that is contained in the notice
announcing the meeting of the Company Preferred Securities, (ii) a statement
that the Holders of the Trust Preferred Securities shall be entitled, subject to
any applicable provision of law, to direct the Trustee specifically as to the
exercise of the voting rights pertaining to the number of the Company Preferred
Securities represented by their respective Trust Preferred Securities, and (iii)
a brief description of the manner in which the Holders of the Trust Preferred
Securities may give such specific directions.

            If the Trust receives a written direction from a Holder, the Trustee
shall vote, or cause to be voted, the number of Company Preferred Securities
corresponding to such Holder's Trust Preferred Securities in accordance with the
instructions set forth in the direction. If the Trustee does not receive
specific instructions from any Holder, the Trustee shall abstain from voting the
Company Preferred Securities corresponding to such Holder's Trust Preferred
Securities.

            The Grantor hereby agrees to take all reasonable action that may be
deemed necessary by the Trustee in order to enable the Trustee to vote such
Company Preferred Securities or cause such Company Preferred Securities to be
voted.

                                   ARTICLE VI
                                   THE TRUSTEE

            Section 6.01. Eligibility. The Trust shall at all times have a
Trustee that is not an Affiliate of the Grantor and is a bank that is organized
and doing business under the laws of the State of Delaware, authorized under
such laws to exercise corporate trust powers, having a combined capital and
surplus of at least $50,000,000 and subject to supervision or examination by
Federal or State authority. If such bank publishes reports of conditions at
least annually, pursuant to law or to the requirements of Federal or State
supervising or examining authority, then for the purposes of this Section 6.01,
the combined capital and surplus of such bank shall be deemed to be its combined
capital and surplus as set forth in its most recent report of conditions so
published.

            If the Trustee ceases to be eligible in accordance with the
provisions of this Section 6.01, the Trustee shall resign immediately in the
manner and with the effect specified in Section 6.03.

            If the Trustee has or shall acquire any "conflicting interest"
within the meaning of Section 310(b) of the Trust Indenture Act, the Trustee and
the Grantor (as if it were the obligor referred to in Section 310(b) of the
Trust Indenture Act) shall in all respects comply with the provisions of Section
310(b) of the Trust Indenture Act.

            The Trustee shall make available for inspection by Holders of the
Trust Preferred Securities at the Corporate Office and at such other places as
it may from time to time deem advisable during normal business hours any reports
and communications received from the Grantor by the Trustee as the holder of the
Company Preferred Securities.

            Promptly upon request from time to time by the Grantor, the Trustee
shall cause the Registrar to furnish to it a list as of a recent date, of the
names, addresses and holdings of all Persons in whose names Trust Preferred
Securities are registered on the Register.

            Section 6.02. Obligations of the Trustee.

            (a) The Trustee, before the occurrence of any default with respect
to the Trust Preferred Securities and after the curing or waiver of all such
defaults that may have occurred, shall undertake to perform only such duties as
are specifically set forth in this Trust Agreement and no implied covenants
shall be read into this Trust Agreement against the Trustee. In case a default
with respect to the Trust Preferred Securities has occurred (that has not been
cured or waived pursuant to Section 2.06) of which an officer of the Trustee has
actual knowledge, the Trustee shall exercise such of the rights and powers
vested in it by this Trust Agreement, and use

                                      -18-
<PAGE>
the same degree of care and skill in their exercise, as a prudent person would
exercise or use under the circumstances in the conduct of his or her own
affairs. Subject to these requirements, the Trustee shall be under no obligation
to exercise any of the powers vested in it by this Trust Agreement at the
request of any Holder, unless such Holder offers the Trustee reasonable
indemnity against all costs, expenses and liabilities that might be incurred by
exercising those powers.

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

                  (i) prior to the occurrence of a default with respect to the
      Trust Preferred Securities and after the curing or waiving of all such
      defaults that may have occurred:

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

                        (B) in the absence of bad faith on the part of the
            Trustee, the Trustee may conclusively rely, as to the truth of the
            statements and the correctness of the opinions expressed therein,
            upon any certificates or opinions furnished to the Trustee and
            conforming to the requirements of this Trust Agreement; provided
            that in the case of any such certificates or opinions that by any
            provision hereof are specifically required to be furnished to the
            Trustee, the Trustee shall be under a duty to examine the same to
            determine whether or not they conform to the requirements of this
            Trust Agreement, but need not confirm or investigate the accuracy of
            any mathematical calculations or other facts stated therein;

                  (ii) the Trustee shall not be liable for any error of judgment
      made in good faith by an officer of the Trustee, unless it shall be proved
      that the Trustee was negligent in ascertaining the pertinent facts;

                  (iii) the Trustee shall not be liable with respect to any
      action taken or omitted to be taken by it in good faith in accordance with
      the direction of the Holders of not less than 50% in liquidation amount of
      the Trust Preferred Securities relating to the time, method and place of
      conducting any proceeding for any remedy available to the Trustee, or
      exercising any trust or power conferred upon the Trustee under this Trust
      Agreement; and

                  (iv) the Trustee's sole duty with respect to the custody safe
      keeping and physical preservation of the Company Preferred Securities, the
      Subordinated Guarantee and the Trust Preferred Securities shall be to deal
      with such property in a similar manner as the Trustee deals with similar
      property for its own account, subject to

                                      -19-
<PAGE>
      the protections and limitations on liability afforded to the Trustee under
      this Trust Agreement and the Trust Indenture Act.

            (c) The Trustee shall:

                  (i) cause its authorized signatories to execute and deliver on
      behalf of the Trust: (1) the Paying Agency Agreement, dated _______ __,
      200-, among the Company, the Trust, and Paying Agent, (2) the Registrar
      and Transfer Agency Agreement, dated _______ __, 200-, among the Trust,
      Wilmington Trust Company and [Name of Registrar and Transfer Agent], as
      Registrar and Transfer Agents for the Trust Preferred Securities, (3) the
      global certificate in respect of the Trust Preferred Securities, and (4)
      any and all additional documents as may be desirable in connection with
      the offering of the Trust Preferred Securities representing the Company
      Preferred Securities; and

                  (ii) cause its authorized signatories to execute and deliver:
      (1) a Certificate of the Trustee, dated _______ __, 200-, pursuant to
      Section 5(i) of the Underwriting Agreement, and (ii) a Certificate of the
      Trustee, dated _______ __, 200-, attaching the Trust Agreement as may be
      amended from time to time and stating that the signatures on documents
      signed by the Trustee on behalf of the Trust are authorized and genuine.

            The Grantor may instruct the Trustee to dissolve the Trust and
distribute the Trust Estate on a pro rata basis to the Holders of the Trust
Preferred Securities in the case of either a Tax Event as to the Trust or an
Investment Company Act Event as to the Trust, as such is defined in the LLC
Agreement.

            In the event that the Trustee is uncertain as to application or
interpretation of any provision of this Trust Agreement or must choose between
alternative courses of action, the Trustee may seek the instructions of the
Grantor by written notice requesting instructions. The Trustee shall take and be
protected in taking such action as has been directed by the Grantor; provided
that, if the Trustee does not receive instructions within ten days or such
shorter time as is set forth in such notice, the Trustee shall be under no duty
to take or refrain from taking such action and shall be fully protected in any
course of action taken by it in good faith not inconsistent with this Trust
Agreement as it shall deem advisable and in the interest of the Holders of the
Trust Preferred Securities.

            The Trustee and its Affiliates may own, buy, sell or deal in any
class of securities of the Grantor and its Affiliates and in Trust Preferred
Securities or become pecuniarily interested in any transaction in which the
Grantor or its Affiliates may be interested or contract with or lend money to or
otherwise act as fully or as freely as if it were not the Trustee hereunder. The
Trustee may also act as transfer agent or registrar of any of the securities of
the Grantor and its Affiliates or act in any other capacity for the Grantor or
its Affiliates.

            The Trustee (and its officers, directors, employees and agents)
makes no representation nor shall it have any liability for or responsibility
with respect to the issuance of

                                      -20-
<PAGE>
the Trust Preferred Securities (except for its counter-signatures thereon) or
any instruments referred to therein or herein, or as to the correctness of any
statement made therein or herein; provided, however, that the Trustee is
responsible for its representations and warranties in the last paragraph of this
Section 6.02.

            The Trustee assumes no responsibility for the correctness of the
description that appears in the Trust Preferred Securities, which can be taken
as a statement of the Grantor summarizing certain provisions of this Trust
Agreement. Notwithstanding any other provision herein or in the Trust Preferred
Securities, the Trustee makes no warranties or representations as to the
validity, genuineness or sufficiency of the Trust Preferred Securities, as to
the validity or sufficiency of this Trust Agreement, as to the value of the
Trust Preferred Securities or as to any right, title or interest of the Holders
of the Trust Preferred Securities, except that the Trustee hereby represents and
warrants as follows: (i) the Trustee has been duly organized and is validly
existing and in good standing under Delaware law, with full power, authority and
legal right under such laws to execute, deliver and carry out the terms of this
Trust Agreement; (ii) this Trust Agreement has been duly authorized, executed
and delivered by the Trustee; and (iii) this Section 5.02 constitutes a valid
and binding obligation of the Trustee enforceable against the Trustee in
accordance with its terms subject to equitable principles and bankruptcy,
insolvency, moratorium, receivership and other similar laws affecting the
enforcement of creditors' rights generally. Notwithstanding anything herein or
in any other document to the contrary, to the maximum extent provided in Section
3803(b) of the Statutory Trust Act, a trustee of the Trust, when acting in such
capacity, shall not be personally liable to any Person other than the Trust and
the beneficial owners thereof for any act, omission or obligation of the Trust
or any other trustee or other agent or representative of the Trust.

            In the exercise or administration of the trusts hereunder, the
Trustee (i) may act directly or, at the expense of the Trust, through agents or
attorneys, and the Trustee shall not be liable for the default or misconduct of
such agents or attorneys if such agents or attorneys shall have been selected by
the Trustee in good faith, and (ii) may, at the expense of the Trust, consult
with counsel, accountants and other experts, and it shall not be liable for
anything done, suffered or omitted in good faith by it in accordance with the
advice or opinion of any such counsel, accountants or other experts.

            Section 6.03. Resignation and Removal of the Trustee; Appointment of
Successor Trustee. The Trustee may resign as Trustee at any time by giving
notice of its resignation to the Grantor. The Trustee may be removed by the
Grantor at any time by notice of such removal delivered to the Trustee. Any
resignation or removal of the Trustee shall take effect upon the appointment of
a qualified successor trustee and the successor's acceptance of such appointment
as hereinafter provided.

            If the Trustee shall resign or be removed, the Grantor shall, within
45 days after the delivery of the notice of resignation or removal, as the case
may be, appoint a successor trustee, which shall be a bank or trust company, or
an affiliate of a bank or trust company, having its principal office in the
State of Delaware and having a combined capital and surplus of at least

                                      -21-
<PAGE>
            If a successor Trustee shall not have been appointed in 45 days, the
resigning Trustee may petition a court of competent jurisdiction to appoint a
successor trustee, and the expenses of such proceeding shall be borne by the
Grantor. Every successor trustee shall execute and deliver to its predecessor
and to the Grantor an instrument in writing accepting its appointment hereunder,
and thereupon the resigning or removed Trustee shall be fully released and
discharged of the trusts and duties of the Trustee hereunder and such successor
trustee, without any further act or deed, shall become fully vested with all the
rights, powers, duties and obligations of its predecessor and for all purposes
shall be the Trustee under this Trust Agreement, and such predecessor, upon
payment of all sums due it and on the written request of the Grantor, shall
promptly execute and deliver an instrument transferring to such successor all
rights and powers of such predecessor hereunder, shall duly assign, transfer and
deliver all rights, title and interest in the Company Preferred Securities and
any moneys or property held hereunder to such successor and shall deliver to
such successor a list of the Holders of all outstanding Trust Preferred
Securities. Any successor Trustee shall promptly mail notice of its appointment
to the Holders of the Trust Preferred Securities.

            Any Person into or with which the Trustee may be merged,
consolidated or converted, or any Person succeeding to the corporate trust
business of the Trustee, shall be the successor of such Trustee without the
execution or filing of any document or any further act, provided such Person
shall be eligible under the provisions of the immediately preceding paragraph.

            Section 6.04. Notices. The Grantor agrees that it shall give timely
notice to the Trustee and any Paying Agent of any record date for the Company
Preferred Securities Certificates, which record date shall become the record
date with respect to the Trust Preferred Securities pursuant to Section 5.04.

behalf of the Trust.

            Section 6.06. Appointment of Grantor to File on Behalf of Trust. The
Grantor and the Trustee hereby appoint, authorize and direct the Grantor, if the

capital securities an exemption from, the securities "Blue Sky" laws; (iii) to
execute on behalf of the Trust such underwriting or purchase or placement agent
agreements

                                      -22-

offering of the Trust Preferred Securities of the Trust; (iv) to execute on
behalf of the Trust any and all documents, papers and instruments as may be
desirable in connection with any of the foregoing; and (v) to file and execute

the Trust, may deem necessary or desirable. In the event that any filing

state securities or Blue Sky laws to be executed on behalf of the Trust by the
Trustee or the Grantor, the Trustee, in its capacity as trustee of the Trust,
and the Grantor are hereby authorized and directed to join in any such filing

understood that the Trustee, in its capacity as trustee of the Trust, shall not
be required to join in any such filing or execute on behalf of the Trust any
such document unless required by the rules and regulations of such state
securities or "Blue Sky" laws.

            Section 6.07. Indemnification by the Grantor. To the fullest extent
permitted by law, the Grantor and the Bank, jointly and severally, agree to
indemnify and defend the Trustee, the Registrar and any Paying Agent and their
directors, officers, employees and agents against, and hold each of them
harmless from, any liability, costs and expenses (including reasonable
attorneys' fees) that may arise out of or in connection with its acting as the
Trustee or the Registrar, transfer agent or Paying Agent, respectively, under
this Trust Agreement and the Trust Preferred Securities, except for any
liability arising out of gross negligence, bad faith or willful misconduct on
the part of any such Person or Persons. This Section 6.07 and Section 6.08 and

the Trust, including the charges or expenses of the Trustee or any Trustee's
agent hereunder or of any Registrar, shall be paid by the Stamford branch of UBS

other Person, such Holder or other Person shall be liable for such fees, charges
and expenses.

            (a) Notwithstanding any other provisions of this Trust Agreement, at
any time, for the purpose of meeting any legal requirements of any jurisdiction
in which any property of the Trust must at the time be located, the Trustee
shall have the power and may execute and deliver all instruments to appoint one
or more Persons to act as co-trustee or co-trustees, or separate trustee or
separate trustees, of all or any part of the Trust, and to vest in such Person
or Persons, in such capacity and for the benefit of the Holders of the Trust
Preferred Securities, such title to the Trust, or any part thereof, and, subject
to the other provisions of this Section 6.09, such powers, duties, obligations,
rights and trusts as the Trustee may consider necessary or desirable. No

conditions:

                  (i) all rights, powers, duties and obligations conferred or
      imposed upon and exercised or performed by the Trustee shall be exercised
      or performed by the Trustee and such separate trustee or co-trustee
      jointly (it being understood that such separate trustee or co-trustee is
      not authorized to act separately without the Trustee joining in such act),
      except to the extent that under any laws of any jurisdiction in which any
      particular act or acts are to be performed, the Trustee shall be
      incompetent or unqualified to perform such act or acts, in which event,
      such rights, powers, duties and obligations (including the holding of
      title to the Trust or any portion thereof in any such jurisdiction) shall

      but solely at the direction of the Trustee;

                  (ii) the Trustee shall be personally liable by reason of any
      act or omission of any separate trustee or co-trustee; and

                  (iii) the Trustee may at any time accept the resignation of or
      remove any separate trustee or co-trustee.

            (c) Any notice, request or other writing given to the Trustee shall

co-trustees, as effectively as if given to each of them. Every instrument
appointing any separate trustee or co-trustee shall refer to this Trust
Agreement. Each separate trustee and co-trustee, upon its acceptance of the
trusts conferred, shall be vested with the estates or property specified in its
instrument of appointment, either jointly with the Trustee or separately, as may
be provided therein, subject to all the provisions of this Trust Agreement,
specifically including every provision of this Trust Agreement relating to the
conduct of, affecting the liability of, or affording protection to, the Trustee.

deposited in trust by the Grantor with the Trustee pursuant to an Amended and
Restated Trust Agreement of UBS Preferred Funding Trust IV, dated as of _______

Grantor, as amended, a copy of which is on file at the Corporate Office of the
Trustee.

            (i) The Trust Agreement. The Trust Preferred Securities are issued
upon the terms and conditions set forth in the Trust Agreement. The Trust
Agreement (a copy of which is on file at the Corporate Office of the Trustee)
sets forth the rights of Holders of the Trust Preferred Securities and the
rights and duties of the Trustee and the Grantor. The statements made herein are
summaries of certain provisions of the Trust Agreement and are subject to the
detailed provisions thereof, to which reference is hereby made. In the event of
any conflict or discrepancy between the provisions hereof and the provisions of
the Trust Agreement, the provisions of the Trust Agreement shall govern. Unless
otherwise expressly herein provided, all defined terms used herein shall have
the meanings ascribed thereto in the Trust Agreement.

            (ii) Enforcement of Rights; Withdrawal of Company Preferred
Securities. To the fullest extent permitted by law, without the need for any
other action of any Person, including the Trustee or any other Holder, each
Holder shall be entitled to enforce, in the name of the Trust, the rights of the
Trust in respect of the number of Company Preferred Securities and the
Subordinated Guarantee corresponding to the Trust Preferred Certificates held by
such Holder. Any recovery on such enforcement action shall belong solely to such
Holder who brought the action, not to the Trust, the Trustee or any other Holder
individually or to Holders as a group.

               Any beneficial owner of Trust Preferred Securities may withdraw
all, but not less than all, of the number of Company Preferred Securities
corresponding to such Trust Preferred Securities by providing a written notice
to the Trustee, with evidence of beneficial ownership in form satisfactory to

            (iv) Redemptions of Company Preferred Securities. The Trust
Preferred Securities shall be redeemed only upon redemption of the Company
Preferred Securities.

               If the Grantor redeems the Company Preferred Securities in
accordance with the LLC Agreement, then the Grantor shall give the Trustee at
least 30 days' prior notice before doing so. The Trustee shall mail the notice
of the redemption not less than 25 days prior to the date fixed for redemption
of the Company Preferred Securities to the Holders of the Trust Preferred
Securities. No defect in the notice of redemption or in the mailing or delivery

redemption proceedings.

               If only some of the outstanding Trust Preferred Securities are to
be redeemed, the Trust Preferred Securities to be redeemed shall be selected in
accordance with DTC's procedures. If the Trust Preferred Securities do not
remain registered in the name of DTC or its nominee and only some of the
outstanding Trust Preferred Securities are to be redeemed, the Trust Preferred
Securities shall be redeemed proportionally or selected for redemption pursuant
to the rules of any securities exchange on which the Trust Preferred Securities
are listed at that time. The Grantor shall promptly notify in writing the
Registrar and Transfer Agent for the Trust Preferred Securities of the Trust
Preferred Securities selected for redemption.

               On the date of redemption of the Company Preferred Securities, so
long as the Company or the Bank has deposited with the Paying Agent on behalf of
the Trust the aggregate amount payable upon redemption of all the Company
Preferred Securities held by the Trust to be redeemed, the Paying Agent on
behalf of the Trust shall irrevocably deposit with DTC funds sufficient to pay
the redemption price and give DTC irrevocable instructions to pay the redemption
price to the Holders of the Trust Preferred Securities to be redeemed.

            (v) Distributions in Liquidation of Grantor. Upon receipt by the
Trust of any Liquidation Preference from the Grantor upon the liquidation of the
Grantor, after satisfaction of creditors of the Trust required by applicable
law, the Trust shall distribute the same to Holders of the Trust Preferred
Securities on the record date therefor, in proportion to the respective
Liquidation Preference of the number of Company Preferred Securities
corresponding to the Trust Preferred Securities held by such Holders.

            (vi) Fixing of Record Date for Holders of the Trust Preferred
Securities. Each Regular Distribution on the Trust Preferred Securities shall be
payable to the Holders of record as they appear on the Register on the
corresponding record date. The record date for Regular Distributions is the
fifteenth calendar day prior to the relevant distribution date. Whenever any
other distribution shall become payable, or whenever the Trustee shall receive
notice of any meeting at which holders of the Company Preferred Securities are
entitled to vote or of which holders of the Company Preferred Securities are
entitled to notice, the Trustee shall in each such instance fix a record date
(which shall be the same date as the record date fixed by the Grantor with
respect to the Company Preferred Securities, of which the Grantor shall promptly
inform the Trustee) for the determination of the Holders of the Trust Preferred
Securities who shall be entitled (i) to receive such distribution or (ii) to
receive notice of, and to give instructions for the exercise of voting rights
at, any such meeting.

            (vii) Payment of Distributions. As long as the Trust Preferred
Securities are in book-entry form, payments on the Trust Preferred Securities

scheduled payment dates. The payments shall be distributed to participants,
indirect participants and beneficial owners of the Trust Preferred Securities in
accordance with DTC's procedures.

               If definitive Trust Preferred Securities are issued, payments on
the Trust Preferred Securities shall be made by check mailed to the address of
the Holder entitled to receive the payment, as address appears in the Register.
Payments of the redemption price of, and distributions in liquidation on, Trust
Preferred Securities shall be made upon surrender of such Trust Preferred
Securities at the office of the Paying Agent.

            (viii) Voting Rights. If at any time, the holders of Company
Preferred Securities are entitled to vote under the LLC Agreement, the Trustee
shall: (i) notify the Holders of the Trust Preferred Securities of such right,
(ii) request specific direction from each Holder as to the vote with respect to
the Company Preferred Securities represented by such Holder's Trust Preferred
Securities, and (iii) vote the relevant Company Preferred Securities only in
accordance with such specific direction.

               Upon receiving notice of any meeting at which the holders of
Company Preferred Securities are entitled to vote, the Trustee shall, as soon as
practicable, mail to the Holders of the Trust Preferred Securities a notice. The
Company shall provide the form of notice to the Trustee to be forwarded to the
Holders of the Trust Preferred Securities. The notice shall contain: (i) all the
information that is contained in the notice announcing the meeting of the
Company Preferred Securities, (ii) a statement that the Holders of the Trust
Preferred Securities shall be entitled, subject to any applicable provision of
law, to direct the Trustee specifically as to the exercise of the voting rights
pertaining to the number of the Company Preferred Securities represented by
their respective Trust Preferred Securities, and (iii) a brief description of
the manner in which the Holders of the Trust Preferred Securities may give such
specific directions.

               If the Trust receives a written direction from a Holder, the
Trustee shall vote, or cause to be voted, the amount of the Company Preferred
Securities represented by such Holder's Trust Preferred Securities in accordance
with the instructions set forth in the directions. If the Trustee does not
receive specific instructions from any Holder, the Trustee shall abstain from
voting the Company Preferred Securities represented by such Holder's Trust
Preferred Securities.

            (ix) Currency. All distribution and other payments and all other
monetary rights and obligations in respect of the Trust Preferred Certificates
shall be performed in U.S. dollars.

            (x) Transfer and Exchange of Trust Preferred Securities. Subject to
the terms and conditions of the Trust Agreement, the Registrar shall register
the transfers on the Register from time to time of Trust Preferred Securities
upon any surrender thereof by the Holder in person or by a duly authorized
attorney, properly endorsed or accompanied by a properly executed instrument of
transfer or endorsement, together with evidence of the payment of any transfer
taxes as may be required by law. Upon such surrender, the Trustee shall execute
a new Trust

                                      A-4
<PAGE>
Preferred Security representing the same corresponding amount of the Company
Preferred Securities and deliver the same to or upon the order of the Person
entitled thereto.

Registrar or such other office as the Trustee may designate for the purpose of
effecting an exchange of Trust Preferred Securities, subject to the conditions
to transfer set forth in the Trust Agreement, the Trustee shall execute and
deliver a new Trust Preferred Security representing the same corresponding
amount of Company Preferred Securities as the Trust Preferred Security
surrendered.

               As a condition precedent to the registration of the transfer or
exchange of any Trust Preferred Security, the Registrar, may require (i) the
production of proof satisfactory to it as to the identity and genuineness of any
signature; (ii) compliance with such regulations, if any, as the Trustee or the
Registrar may establish not inconsistent with the provisions of the Trust
Agreement; and (iii) such other information as the Registrar may reasonably
request.

               No Holder may require the transfer of any Trust Preferred
Security to be registered during the period of fifteen days ending on the due
date for any payment of the Liquidation Preference on the Trust Preferred
Securities. The trust shall not be required to register, or cause others to
register, the transfer of Trust Preferred Securities after such Trust Preferred
Securities have been called for redemption.

            (xi) Title to Trust Preferred Securities. It is a condition of the
Trust Preferred Securities, and every successive Holder hereof by accepting or
holding the same consents and agrees, that title to this Trust Preferred
Security, when properly endorsed or accompanied by a properly executed
instrument of transfer or endorsement, is transferable by delivery with the same
effect as in the case of a negotiable instrument; provided, however, that until
the transfer of this Trust Preferred Security shall be registered on the books
of the Trust, the Trustee, the Registrar and the Grantor may, notwithstanding
any notice to the contrary, treat the Holder hereof at such time as the absolute
owner hereof for the purpose of determining the Person entitled to distributions
or to any notice provided for in the Trust Agreement and for all other purposes.

            (xii) Reports, Inspection of Transfer Books. The Trustee shall make
available for inspection by Holders of the Trust Preferred Securities at the
Corporate Office and at such other places as it may from time to time deem
advisable during normal business hours any reports and communications received

Registrar shall keep books at the Corporate Office for the registration of
transfer of Trust Preferred Securities, which books at all reasonable times
shall be open for inspection by the Holders of the Trust Preferred Securities as
and to the extent provided by applicable law.

shall, to the extent applicable, be governed by such provisions. A term defined

date for payment of Dividends, as of such record date and (ii) at any other
time, within 30 days of receipt by the Trust of a written request from the
Trustee for such List, as of a date no more than 14 days before such List of

certificate required by Section 314 of the Trust Indenture Act in the form and
manner and at the times required by Section 314 of the Trust Indenture Act.
Delivery of such reports, information and documents to the Trustee is for

constitute constructive notice of any information contained therein or
determinable from information contained therein, including the Trust's
compliance with any of its covenants hereunder (as to which the Trustee is
entitled to rely exclusively on Officers' Certificates).

                  Section 2.05. Evidence of Compliance with Conditions
Precedent. The Grantor shall provide to the Trustee evidence of compliance with
the conditions precedent, if any, provided for in this Trust Agreement that

                  Section 2.06. Defaults; Waiver.

                  (a) The Holders of a majority in liquidation amount of the
Trust Preferred Securities may, by vote, on behalf of the Holders of all of the
Trust Preferred Securities, waive any past default in respect of the Trust
Preferred Securities and its consequences; provided that, if the underlying
event of default is also a default in respect of the Company Preferred
Securities and:

                           (i) is not waivable under the LLC Agreement, the
         default under this Trust Agreement shall also not be waivable; or

                           (ii) requires the consent or vote of the holders of
         more than 50% of the aggregate liquidation preference of the Company
         Preferred Securities to be waived under the LLC Agreement (a "Super
         Majority"), the default under this Trust Agreement may only be waived
         by the vote of the Holders of at least the relevant Super Majority in
         liquidation amount of the Trust Preferred Securities.

                  The foregoing provisions of this Section 2.06(a) shall be in
lieu of Section 316(a)(1)(B) of the Trust Indenture Act and such Section
316(a)(1)(B) of the Trust Indenture Act is hereby expressly excluded from this
Trust Agreement and the Trust Preferred Securities, as permitted by the Trust
Indenture Act. Upon such waiver, any such default shall cease to exist, and any
default with respect to the Trust Preferred Securities arising therefrom shall
be deemed to have been cured, for every purpose of this Trust Agreement, but no
such waiver shall extend to any subsequent or other default with respect to the
Trust Preferred Securities or impair any right consequent thereon.

                  (b) A waiver of a default under the LLC Agreement by the
Trustee at the direction of the Holders of the Trust Preferred Securities
constitutes a waiver of the corresponding default under this Trust Agreement.
The foregoing provisions of this Section 2.06(b) shall be in lieu of Section
316(a)(1)(B) of the Trust Indenture Act and such Section

the Holders of the Trust Preferred Securities, notices of all defaults with
respect to the Trust Preferred Securities actually known to the Trustee, unless
such defaults shall have been cured before the giving of such notice; provided
that, the Trustee shall be protected in withholding such notice if and so long
as the Trustee in good faith determines that the withholding of such notice is
in the interests of the Holders of the Trust Preferred Securities.

the Trust continued hereby constitute a statutory trust under the Statutory
Trust Act and that this Agreement constitute the governing instrument of the
Trust. The Trust exists for the sole purpose of issuing Trust Preferred
Securities representing an undivided beneficial interest in the Company
Preferred Securities held by the Trust and performing functions directly related

or more Company Preferred Securities Certificates representing Company Preferred

of the Holders of the Trust Preferred Securities. To the fullest extent
permitted by law, without the need for any other action of any Person, including
the Trustee or any other Holder, each Holder shall be entitled to enforce, in
the name of the Trust, the rights of the Trust under the Company Preferred
Securities and the Subordinated Guarantee represented by the Trust Preferred
Securities held by such Holder. Any recovery on such an enforcement action shall
belong solely to such Holder who brought the action, not to the Trust, the
Trustee or any other Holder individually or to the Holders as a group. The
Trustee shall have the power and authority (subject to the Trustee's rights,
privileges and protections in Section 6.02 and elsewhere herein) to enforce any
of the Trust's rights in respect of the Company Preferred Securities which are
not enforced by any Holder. Subject to Section 7.02, the Trust shall be
irrevocable.

                  (b) The Trustee hereby acknowledges receipt of one or more
Company Preferred Securities Certificates representing Company Preferred
Securities having an aggregate liquidation preference of $- registered in
the name of the Trust, and its acceptance on behalf of the Trust of the Company
Preferred Securities, and declares that the Trust shall hold the Company
Preferred Securities for the benefit of the Holders of the Trust Preferred
Securities.

endorsed or accompanied by a properly executed instrument of transfer or
endorsement shall be transferable by delivery with the same effect as in the
case of a negotiable instrument; provided, however, that until the transfer
shall be registered on the Register as provided in Section 4.03, the Trust, the
Trustee, the Registrar and the Grantor may, notwithstanding any notice to the
contrary, treat the Holder thereof at such time as the absolute owner thereof

Trustee by the manual signature of a duly authorized signatory of the Trustee,

Preferred Security shall be entitled to any benefit under this Trust Agreement

hereinafter provided. Trust Preferred Securities bearing the signatures of
individuals who were, at the time when such signatures shall have been affixed,
authorized to sign on behalf of the Trustee shall be validly issued

authorized prior to the delivery of such Trust Preferred Securities or did not

                  (b) Beneficial interests in the Trust Preferred Securities
will be evidenced by, and transfers thereof will be effected only through,
records maintained by the Clearing Agency Participants. Unless and until

                           (i) the provisions of this Section 4.02(b) shall be

         Agency and/or the Clearing Agency Participants, and the Clearing Agency
         shall receive and transmit payments of Dividends on the Global
         Certificate to such Clearing Agency Participants. The Clearing Agency
         will make book-entry transfers among the Clearing Agency Participants;
         provided, that solely for the purposes of determining whether the
         Holders of the requisite amount of Trust Preferred Securities have
         voted on any matter provided for in this Trust Agreement, so long as
         Definitive Trust Preferred Securities Certificates have not been issued
         to the Owners pursuant to Section 4.03(c), the Trustee may conclusively
         rely on, and shall be fully protected in relying on, any written
         instrument (including a proxy) delivered to the Trustee by any Clearing
         Agency setting forth the Owners' votes or assigning the right to vote
         on any matter to any other Persons either in whole or in part.

                  (c) Notices to Clearing Agency. Whenever a notice or other
communication to the Holders is required under this Trust Agreement, unless and

Securities, the Grantor and the Trust shall use their best efforts to appoint a
successor Clearing Agency with respect to the Trust Preferred Securities.

                  Section 4.03. Registration, Transfer and Exchange of Trust
Preferred Securities.

                  (a) The Trustee shall cause a Register (the "Register") to be
kept at the office of the Registrar in which, subject to such reasonable
regulations as the Trustee and the Registrar may prescribe, the Trustee shall
provide for the registration of Trust Preferred Securities and of transfers and
exchanges of Trust Preferred Securities as herein provided. In the absence of
appointing a third party, the Trustee shall serve as the Registrar. The Grantor
may remove the Registrar and, upon removal or resignation of the Registrar,
appoint a successor Registrar. Subject to the terms and conditions of this Trust
Agreement, the Registrar shall register the transfers on the Register from time
to time of Trust Preferred Securities upon any surrender thereof by the Holder
in person or by a duly authorized attorney, properly endorsed or accompanied by
a properly executed instrument of transfer or endorsement, together with
evidence of the payment of any transfer taxes as may be required by law. Upon
such surrender, the Trustee shall execute a new Trust Preferred Security
representing the same corresponding amount of Company Preferred Securities in
accordance with Section 4.01(e) and deliver the same to or upon the order of the
Person entitled thereto.

                  (b) At the option of a Holder, Trust Preferred Securities may
be exchanged for other Trust Preferred Securities representing the same
corresponding amount of Company Preferred Securities. Upon surrender of a Trust
Preferred Security at the office of the Registrar or such other office as the
Trustee may designate for the purpose of effecting an exchange of Trust
Preferred Securities, subject to the conditions to transfer set forth in this
Trust Agreement, the Trustee shall execute and deliver a new Trust Preferred
Security representing the same corresponding amount of Company Preferred
Securities as the Trust Preferred Security surrendered.

                  As a condition precedent to the registration of the transfer
or exchange of any Trust Preferred Security, the Registrar may require (i)
production of proof satisfactory to it as to the identity and genuineness of any
signature; (ii) compliance with such regulations, if any, as the Trustee or the
Registrar may establish not inconsistent with the provisions of this Trust
Agreement; and (iii) such other information as the Registrar may reasonably
request.

                  No Holder may require the transfer of any Trust Preferred
Security to be registered during the period of fifteen days ending on the due
date for any payment of principal on the Trust Preferred Securities. The Trust
shall not be required to register, or cause others to register, the transfer of
Trust Preferred Securities after such Trust Preferred Securities have been
called for redemption.

                  Registration of transfers of Trust Preferred Securities,
including Trust Preferred Securities Certificates, shall be made without change
by the Trust, but the transferor must pay any tax or governmental charge that
may be imposed in relation to the transfer, together with any indemnity that the
Trust or the Bank or the Transfer Agent may require.

                  (c) The Global Certificate is exchangeable for Definitive
Trust Preferred Security Certificates in registered form if DTC: (i) notifies
the Trust that it is unwilling or unable to continue as depositary for the
Global Certificate and the Trust does not appoint a successor depositary or (ii)
has ceased to be a clearing agency registered under the Securities Exchange Act
of 1934. Upon surrender of the Global Certificates by the Clearing Agency,
accompanied by registration instructions, the Grantor will cause to be prepared
for delivery to the Owners the Definitive Trust Preferred Certificates in
accordance with instructions of the Clearing Agency.

                  Definitive Trust Preferred Securities Certificates may be
transferred in any whole-number multiples of $[1,000][25] by surrendering the
Definitive Trust Preferred Securities Certificates, together with the form of
transfer endorsed on it, duly completed and executed, at the specified office of
the Transfer Agent. The initial Transfer Agent shall be Wilmington Trust
Company. As long as the Trust Preferred Securities are listed on the [insert
applicable stock exchange], the Trust shall also maintain a Transfer Agent in
[insert location/country of applicable stock exchange]. The initial [insert
location/country of applicable stock EXCHANGE] Transfer Agent shall be [Name of
Transfer Agent]. If only part of a Definitive Trust Preferred Securities
Certificate is transferred, a new Definitive Trust Preferred Securities
Certificate representing the securities not transferred shall be issued to the
transferor within three business days after the Transfer Agent receives the
certificate. The new Definitive Trust Preferred Securities Certificate
representing the Trust Preferred Securities that were not transferred shall be
delivered to the transferor by uninsured mail at the risk of the transferor, to
the address of the transferor that appears in the Register. The new Definitive
Trust Preferred Securities Certificate representing the Trust Preferred
Securities that were transferred shall be sent to the transferee within three
business days after the Trustee receives the surrendered Definitive Trust
Preferred Securities Certificate by uninsured mail at the risk of the Holder
entitled to the Definitive Trust Preferred Securities Certificate, to the
address specified on the form of transfer.

                  All transfers of Definitive Trust Preferred Securities
Certificates and entries shall be made as provided in the Registrar and Transfer
Agency Agreement, among the Trust and the Registrar and Transfer Agents,
relating to the Trust Preferred Securities.

                  Section 4.04. Lost or Stolen Trust Preferred Securities, Etc.
If (i) any mutilated Trust Preferred Security shall be surrendered to the
Registrar, or if the Registrar shall receive evidence to its satisfaction of the
destruction, loss or theft of any Trust Preferred Security, and (ii) there shall
be delivered to the Registrar and the Grantor such security or indemnity as may
be required by them to hold each of them harmless, then in the absence of notice
that such Trust Preferred Security shall have been acquired by a bona fide
purchaser or, as applicable, any protected purchaser, the Grantor shall sign and
make available for delivery, in exchange for or in lieu of any mutilated,
destroyed, lost or stolen Trust Preferred Security, a new Trust Preferred
Security representing the same amount of corresponding Company Preferred
Securities. In connection with the issuance of any new Trust Preferred Security,
the Grantor 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 Trust Preferred Security issued pursuant to this Section shall
constitute conclusive evidence of a Trust Preferred Security corresponding to
that
                                      -12-
<PAGE>
evidenced by the lost, stolen or destroyed Trust Preferred Security, as if
originally issued, whether or not the lost, stolen or destroyed Trust Preferred
Security shall be found at any time.

                  Section 4.05. Cancellation and Destruction of Surrendered
Certificates. All Trust Preferred Securities surrendered to the Trustee shall be
canceled by the Trustee. Except as prohibited by applicable law or regulation,
the Trustee may destroy such canceled Trust Preferred Securities or otherwise
dispose of them in accordance with its usual practices.

                  Section 4.06. Surrender of Trust Preferred Securities and
Withdrawal of Company Preferred Securities. Any Person who is the beneficial
owner (an "Owner") of the Trust Preferred Securities represented by the Global
Certificates held by DTC or a successor clearing agency (the "Clearing Agency")
or, if a participant in the Clearing Agency is not the Owner, then as reflected
in the records of a Person maintaining an account with such Clearing Agency
(directly or indirectly), in accordance with the rules of such Clearing Agency,
may withdraw all, but not less than all, of the Company Preferred Securities
represented by such Trust Preferred Securities by providing a written notice to
the Trustee, with evidence of beneficial ownership in form satisfactory to the
Trustee, and providing to the Grantor such documents or information as the
Grantor may request for tax reporting purposes, at the Corporate Office or at
such other office as the Trustee may designate for such withdrawals, all in form
satisfactory to the Trustee, in its sole discretion. The Owner's notice shall
also be deemed to be such Owner's agreement to be subject to the terms of the
LLC Agreement applicable to the rights of holders of the Company Preferred
Securities.

                  Within a reasonable period after such a request has been
properly made, the Trustee shall instruct DTC to reduce the Trust Preferred
Securities represented by the Global Certificate by the corresponding amount of
the Company Preferred Securities to be so withdrawn by the withdrawing Owner.
The Grantor shall issue to the withdrawing Owner a Company Preferred Securities
Certificate representing the amount of the Company Preferred Securities so
withdrawn, and the Trustee, on behalf of the Trust, shall instruct DTC to reduce
the amount of Trust Preferred Securities represented by the Global Certificate
held by DTC by such amount.

                  Any Owner who wishes to withdraw the Company Preferred
Securities in accordance with this Section 4.06 shall be required to provide the
Grantor with a completed Internal Revenue Service Form W-9 or W-8, as
appropriate, and/or such other documents or information as are requested by the
Grantor for tax reporting purposes and thereafter shall be admitted to the
Grantor as a member of the Grantor upon such Owner's receipt of a Company
Preferred Securities Certificate registered in such Owner's name.

                  The Trustee shall deliver the appropriate number of Company
Preferred Securities Certificates in exchange for the Trust Preferred Securities
surrendered in accordance with this Section 4.06 to the Owner at the Corporate
Office, except that, at the request, risk and expense of the Owner and for the
account of the Owner, such delivery may be made at such other place as may be
designated by such Owner. The Trustee shall only deliver such Company Preferred
Securities Certificates upon payment by such Owner to the Trustee of all taxes
and other governmental charges and any fees (including the fees and expenses of
the Trustee and its

                                      -13-
<PAGE>
counsel) payable in connection with such delivery and the transfer of such
Company Preferred Securities Certificates.

                  Notwithstanding anything in this Section 4.06 to the contrary,
if the Company Preferred Securities exchangeable for Trust Preferred Securities
have been called for redemption in accordance with the LLC Agreement, no Owner
of such Trust Preferred Securities may withdraw any or all of the Company
Preferred Securities represented by such Trust Preferred Securities.

                  Section 4.07. Redeposit of Company Preferred Securities. Any
Holder of Company Preferred Securities may redeposit withdrawn Company Preferred
Securities by delivering to the Trustee the Company Preferred Securities
Certificate for the Company Preferred Securities to be deposited, which are (i)
if required by the Trustee, properly endorsed or accompanied by a properly
executed instrument of transfer or endorsement in form satisfactory to the
Trustee and in compliance with the terms of the LLC Agreement and (ii)
accompanied by all such certifications as may be required by the Trustee in its
sole discretion and in accordance with the provisions of this Trust Agreement.
Within a reasonable period after such deposit is properly made, the Trustee
shall instruct DTC to increase the amount of Trust Preferred Securities
represented by the Global Certificate held by DTC by an amount equal to the
Company Preferred Securities so deposited. The Trustee shall only accept the
redeposit of such Company Preferred Securities upon payment by such Holder of
the Company Preferred Securities to the Trustee of all taxes and other
governmental charges and any fees and expenses (including the fees and expenses
of the Trustee and its counsel) payable in connection with such deposit and the
transfer of the deposited Company Preferred Securities.

                  If required by the Trustee, Company Preferred Securities
Certificates presented for redeposit at any time shall also be accompanied by an
agreement or assignment, or other instrument satisfactory to the Trustee, that
shall provide for the prompt transfer to the Trustee or its nominee of any
distribution or other right that any Person in whose name the Company Preferred
Securities Certificates are registered may thereafter receive upon or in respect
of such deposited Company Preferred Securities, or in lieu thereof such
agreement of indemnity or other agreement as shall be satisfactory to the
Trustee.

                  Section 4.08. Filing Proofs, Certificates and Other
Information. Any Person presenting Company Preferred Securities Certificates for
redeposit in accordance with Section 4.06 may be required from time to time to
file such proof of residence or other information, to execute such certificates
and to make such representations and warranties as the Trustee may reasonably
deem necessary or proper.

                  Section 5.01. Periodic Distributions. Whenever (and to the
extent) the Trust receives any cash payments representing a Dividend or
redemption payment on the Company Preferred Securities, or payments from the
Bank pursuant to the Subordinated Guarantee in respect of such Dividend or
redemption payment, the Trustee acting directly or through any Paying Agent
shall distribute such amounts to Holders of the Trust Preferred Securities on
the record date fixed pursuant to Section 5.04, in proportion to the respective
liquidation amount of Trust Preferred Securities held by such Holders.

                  Section 5.02. Redemptions of Company Preferred Securities. The
Trust Preferred Securities shall be redeemed only upon redemption of the Company
Preferred Securities.

                  If the Grantor redeems the Company Preferred Securities in
accordance with the LLC Agreement, then the Grantor shall give the Trustee at
least 30 days' prior notice before doing so. The Trustee shall mail the notice
of the redemption not less than 25 days prior to the date fixed for redemption
(the "Redemption Date") of the Company Preferred Securities to the Holders of
the Trust Preferred Securities as provided under Section 8.04. No defect in the
notice of redemption or in the mailing or delivery thereof shall affect the
validity of the redemption proceedings. The Grantor shall provide the Trustee
with such notice, and each such notice shall state: (i) the Redemption Date,
(ii) the redemption price at which the Trust Preferred Securities and the
Company Preferred Securities are to be redeemed, (iii) that all outstanding
Trust Preferred Securities are to be redeemed or, in the case of a redemption of
fewer than all outstanding Trust Preferred Securities in connection with a
partial redemption of the Company Preferred Securities, the amount of such Trust
Preferred Securities to be so redeemed and (iv) the place or places where Trust
Preferred Securities to be redeemed are to be surrendered for redemption.

                  If only some of the outstanding Trust Preferred Securities are
to be redeemed, the Trust Preferred Securities to be redeemed shall be selected
in accordance with DTC's procedures. If the Trust Preferred Securities do not
remain registered in the name of DTC or its nominee and only some of the
outstanding Trust Preferred Securities are to be redeemed, the Trust Preferred
Securities shall be redeemed proportionally or selected for redemption pursuant
to the rules of any securities exchange on which the Trust Preferred Securities
are listed at that time. The Grantor shall promptly notify the Registrar and
Transfer Agent, in writing, of the Trust Preferred Securities selected for
redemption.

                  The Grantor agrees that if a partial redemption of the Company
Preferred Securities would result in a delisting of the Trust Preferred
Securities from any securities exchange on which the Trust Preferred Securities
are then listed, the Grantor shall only redeem the Company Preferred Securities
in whole.

                  On the date of redemption of the Company Preferred Securities,
so long as the Company or the Bank has deposited with Wilmington Trust Company,
the Paying Agent, on behalf of the Trust the aggregate amount payable upon
redemption of all the Company Preferred Securities held by the Trust to be
redeemed, the Paying Agent on behalf of the Trust shall irrevocably deposit with
DTC funds sufficient to pay the redemption price and give DTC

                                      -15-
<PAGE>
irrevocable instructions to pay the redemption price to the Holders of the Trust
Preferred Securities to be redeemed.

                  Once the Paying Agent has received this deposit, all rights of
the Holders of the Trust Preferred Securities called for redemption shall end,
except their right to receive the redemption price, without interest. If any
date fixed for redemption of the Trust Preferred Securities is not a Business
Day, then the redemption price shall instead be paid on the next Business Day,
except that if that Business Day falls in the next calendar year, the redemption
price shall be paid on the preceding Business Day. No interest or other payment
shall be due as a result of any such adjustment.

                  Section 5.03. Distributions in Liquidation of Grantor. Upon
receipt by the Trust of any Liquidation Preference from the Grantor upon the
liquidation of the Grantor, after satisfaction of creditors of the Trust as
required by applicable law, the Trust shall distribute the same to the Holders
of the Trust Preferred Securities on the record date fixed pursuant to Section
4.04, in proportion to the respective Liquidation Preference of the Company
Preferred Securities which were exchangeable for the Trust Preferred Securities
held by such Holders.

                  Section 5.04. Fixing of Record Date for Holders of the Trust
Preferred Securities. Each distribution on the Trust Preferred Securities in
respect of Dividends on the Company Preferred Securities (each a "Regular
Distribution") shall be payable to the Holders as they appear on the Register on
the corresponding record date. The record date for Regular Distributions is the
fifteenth calendar day prior to the relevant distribution date. Whenever any
other distribution shall become payable, or whenever the Trustee shall receive
notice of any meeting at which Holders of the Company Preferred Securities are
entitled to vote or of which Holders of the Company Preferred Securities are
entitled to notice, the Trustee shall in each such instance fix a record date
(which shall be the same date as the record date fixed by the Grantor with
respect to the Company Preferred Securities, of which the Grantor shall promptly
inform the Trustee) for the determination of the Holders of the Trust Preferred
Securities who shall be entitled (i) to receive such distribution, or (ii) to
receive notice of, and to give instructions for the exercise of voting rights
at, any such meeting.

                  Section 5.05. Payment of Distributions. The Trust shall
maintain a Paying Agent with respect to the Trust Preferred Securities, which
shall initially be Wilmington Trust Company. The Paying Agent shall be permitted
to resign as Paying Agent upon 30 days' written notice to the Trustee. If
Wilmington Trust Company resigns as Paying Agent, the Trustee shall appoint
another bank or trust company to act as Paying Agent. As long as the Trust
Preferred Securities are listed on the [insert applicable stock exchange], the
Trust shall also maintain a Paying Agent in [insert location/country of
applicable stock exchange]. The initial [insert location/country of applicable
stock exchange]Paying Agent shall be [insert name of Paying Agent].

                  As long as the Trust Preferred Securities are in book-entry
form, payments on the Trust Preferred Securities shall be made to DTC, which
shall credit the relevant accounts at DTC on the scheduled payment dates. The
payments shall be distributed to participants, indirect

                                      -16-
<PAGE>
participants and beneficial owners of the Trust Preferred Securities in
accordance with DTC's procedures.

                  If Definitive Trust Preferred Securities Certificates are
issued as described in Section 4.03(c), payments on the Trust Preferred
Securities shall be made by check mailed to the address of the Holder entitled
to receive the payment, as such address appears in the Register.

                  Payments of the redemption price of, and distributions in
liquidation on, Trust Preferred Securities shall be made upon surrender of such
Trust Preferred Securities at the office of the Paying Agent. The Grantor shall
pay Dividends on, the redemption price of, and Liquidation Preferences on, the
Company Preferred Securities directly to the Paying Agent for distribution to
the Holders of the Trust Preferred Securities in accordance with the terms of
this Trust Agreement and the paying agency agreement as then in effect with the
Paying Agent.

                  If any distributions on the Trust Preferred Securities would
be payable on a day that is not a Business Day, that distribution shall instead
be made on the next Business Day. No interest or other payment shall be due as a
result of any such delay.

                  Section 5.06. Voting Rights. If at any time, the holders of
Company Preferred Securities are entitled to vote under the LLC Agreement, the
Trustee shall: (i) notify the Holders of the Trust Preferred Securities of such
right, (ii) request specific direction from each Holder as to the vote with
respect to the Company Preferred Securities represented by such Holder's Trust
Preferred Securities, and (iii) vote the relevant Company Preferred Securities
only in accordance with such specific direction.

                  Upon receiving notice of any meeting at which the holders of
Company Preferred Securities are entitled to vote, the Trustee shall, as soon as
practicable, mail to the Holders of the Trust Preferred Securities a notice as
provided under Section 8.04. The Company shall provide the form of notice to the
Trustee to be forwarded to the Holders of the Trust Preferred Securities. The
notice shall contain: (i) all the information that is contained in the notice
announcing the meeting of the Company Preferred Securities, (ii) a statement
that the Holders of the Trust Preferred Securities shall be entitled, subject to
any applicable provision of law, to direct the Trustee specifically as to the
exercise of the voting rights pertaining to the number of the Company Preferred
Securities represented by their respective Trust Preferred Securities, and (iii)
a brief description of the manner in which the Holders of the Trust Preferred
Securities may give such specific directions.

                  If the Trust receives a written direction from a Holder, the
Trustee shall vote, or cause to be voted, the number of Company Preferred
Securities corresponding to such Holder's Trust Preferred Securities in
accordance with the instructions set forth in the direction. If the Trustee does
not receive specific instructions from any Holder, the Trustee shall abstain
from voting the Company Preferred Securities corresponding to such Holder's
Trust Preferred Securities.

                  The Grantor hereby agrees to take all reasonable action that
may be deemed necessary by the Trustee in order to enable the Trustee to vote
such Company Preferred Securities or cause such Company Preferred Securities to
be voted.

other monetary rights and obligations in respect of the Trust Preferred

                                   THE TRUSTEE

            Section 6.01. Eligibility. The Trust shall at all times have a
Trustee that is not an Affiliate of the Grantor and is a bank that is organized
and doing business under the laws of the State of Delaware, authorized under
such laws to exercise corporate trust powers, having a combined capital and
surplus of at least $50,000,000 and subject to supervision or examination by
Federal or State authority. If such bank publishes reports of conditions at
least annually, pursuant to law or to the requirements of Federal or State
supervising or examining authority, then for the purposes of this Section 6.01,
the combined capital and surplus of such bank shall be deemed to be its combined
capital and surplus as set forth in its most recent report of conditions so
published.

            If the Trustee ceases to be eligible in accordance with the
provisions of this Section 6.01, the Trustee shall resign immediately in the
manner and with the effect specified in Section 6.03.

            If the Trustee has or shall acquire any "conflicting interest"
within the meaning of Section 310(b) of the Trust Indenture Act, the Trustee and
the Grantor (as if it were the obligor referred to in Section 310(b) of the
Trust Indenture Act) shall in all respects comply with the provisions of Section
310(b) of the Trust Indenture Act.

            The Trustee shall make available for inspection by Holders of the
Trust Preferred Securities at the Corporate Office and at such other places as
it may from time to time deem advisable during normal business hours any reports
and communications received from the Grantor by the Trustee as the holder of the
Company Preferred Securities.

            Promptly upon request from time to time by the Grantor, the Trustee
shall cause the Registrar to furnish to it a list as of a recent date, of the
names, addresses and holdings of all Persons in whose names Trust Preferred
Securities are registered on the Register.

            Section 6.02. Obligations of the Trustee.

            (a)   The Trustee, before the occurrence of any default with respect
to the Trust Preferred Securities and after the curing or waiver of all such
defaults that may have occurred, shall undertake to perform only such duties as
are specifically set forth in this Trust Agreement and no implied covenants
shall be read into this Trust Agreement against the Trustee. In case a default
with respect to the Trust Preferred Securities has occurred (that has not been
cured or waived pursuant to Section 2.06) of which an officer of the Trustee has
actual knowledge, the Trustee shall exercise such of the rights and powers
vested in it by this Trust Agreement, and use

                                      -18-
<PAGE>
the same degree of care and skill in their exercise, as a prudent person would
exercise or use under the circumstances in the conduct of his or her own
affairs. Subject to these requirements, the Trustee shall be under no obligation
to exercise any of the powers vested in it by this Trust Agreement at the
request of any Holder, unless such Holder offers the Trustee reasonable
indemnity against all costs, expenses and liabilities that might be incurred by
exercising those powers.

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

                  (i)   prior to the occurrence of a default with respect to the
      Trust Preferred Securities and after the curing or waiving of all such
      defaults that may have occurred:

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

                        (B)   in the absence of bad faith on the part of the
            Trustee, the Trustee may conclusively rely, as to the truth of the
            statements and the correctness of the opinions expressed therein,
            upon any certificates or opinions furnished to the Trustee and
            conforming to the requirements of this Trust Agreement; provided
            that in the case of any such certificates or opinions that by any
            provision hereof are specifically required to be furnished to the
            Trustee, the Trustee shall be under a duty to examine the same to
            determine whether or not they conform to the requirements of this
            Trust Agreement, but need not confirm or investigate the accuracy of
            any mathematical calculations or other facts stated therein;

                  (ii)  the Trustee shall not be liable for any error of
      judgment made in good faith by an officer of the Trustee, unless it shall
      be proved that the Trustee was negligent in ascertaining the pertinent
      facts;

                  (iii) the Trustee shall not be liable with respect to any
      action taken or omitted to be taken by it in good faith in accordance with
      the direction of the Holders of not less than 50% in liquidation amount of
      the Trust Preferred Securities relating to the time, method and place of
      conducting any proceeding for any remedy available to the Trustee, or
      exercising any trust or power conferred upon the Trustee under this Trust
      Agreement; and

                  (iv)  the Trustee's sole duty with respect to the custody safe
      keeping and physical preservation of the Company Preferred Securities, the
      Subordinated Guarantee and the Trust Preferred Securities shall be to deal
      with such property in a similar manner as the Trustee deals with similar
      property for its own account, subject to

                                      -19-
<PAGE>
      the protections and limitations on liability afforded to the Trustee under
      this Trust Agreement and the Trust Indenture Act.

            (c)   The Trustee shall:

                  (i)   cause its authorized signatories to execute and deliver
      on behalf of the Trust: (1) the Paying Agency Agreement, dated _______ __,
      200-, among the Company, the Trust, and Paying Agent, (2) the Registrar
      and Transfer Agency Agreement, dated _______ __, 200-, among the Trust,
      Wilmington Trust Company and [Name of Registrar and Transfer Agent], as
      Registrar and Transfer Agents for the Trust Preferred Securities, (3) the
      global certificate in respect of the Trust Preferred Securities, and (4)
      any and all additional documents as may be desirable in connection with
      the offering of the Trust Preferred Securities representing the Company
      Preferred Securities; and

                  (ii)  cause its authorized signatories to execute and deliver:
      (1) a Certificate of the Trustee, dated _______ __, 200-, pursuant to
      Section 5(i) of the Underwriting Agreement, and (ii) a Certificate of the
      Trustee, dated _______ __, 200-, attaching the Trust Agreement as may be
      amended from time to time and stating that the signatures on documents
      signed by the Trustee on behalf of the Trust are authorized and genuine.

            The Grantor may instruct the Trustee to dissolve the Trust and
distribute the Trust Estate on a pro rata basis to the Holders of the Trust
Preferred Securities in the case of either a Tax Event as to the Trust or an
Investment Company Act Event as to the Trust, as such is defined in the LLC
Agreement.

            In the event that the Trustee is uncertain as to application or
interpretation of any provision of this Trust Agreement or must choose between
alternative courses of action, the Trustee may seek the instructions of the
Grantor by written notice requesting instructions. The Trustee shall take and be
protected in taking such action as has been directed by the Grantor; provided
that, if the Trustee does not receive instructions within ten days or such
shorter time as is set forth in such notice, the Trustee shall be under no duty
to take or refrain from taking such action and shall be fully protected in any
course of action taken by it in good faith not inconsistent with this Trust
Agreement as it shall deem advisable and in the interest of the Holders of the
Trust Preferred Securities.

            The Trustee and its Affiliates may own, buy, sell or deal in any
class of securities of the Grantor and its Affiliates and in Trust Preferred
Securities or become pecuniarily interested in any transaction in which the
Grantor or its Affiliates may be interested or contract with or lend money to or
otherwise act as fully or as freely as if it were not the Trustee hereunder. The
Trustee may also act as transfer agent or registrar of any of the securities of
the Grantor and its Affiliates or act in any other capacity for the Grantor or
its Affiliates.

            The Trustee (and its officers, directors, employees and agents)
makes no representation nor shall it have any liability for or responsibility
with respect to the issuance of

                                      -20-
<PAGE>
the Trust Preferred Securities (except for its counter-signatures thereon) or
any instruments referred to therein or herein, or as to the correctness of any
statement made therein or herein; provided, however, that the Trustee is
responsible for its representations and warranties in the last paragraph of this
Section 6.02.

            The Trustee assumes no responsibility for the correctness of the
description that appears in the Trust Preferred Securities, which can be taken
as a statement of the Grantor summarizing certain provisions of this Trust
Agreement. Notwithstanding any other provision herein or in the Trust Preferred
Securities, the Trustee makes no warranties or representations as to the
validity, genuineness or sufficiency of the Trust Preferred Securities, as to
the validity or sufficiency of this Trust Agreement, as to the value of the
Trust Preferred Securities or as to any right, title or interest of the Holders
of the Trust Preferred Securities, except that the Trustee hereby represents and
warrants as follows: (i) the Trustee has been duly organized and is validly
existing and in good standing under Delaware law, with full power, authority and
legal right under such laws to execute, deliver and carry out the terms of this
Trust Agreement; (ii) this Trust Agreement has been duly authorized, executed
and delivered by the Trustee; and (iii) this Section 5.02 constitutes a valid
and binding obligation of the Trustee enforceable against the Trustee in
accordance with its terms subject to equitable principles and bankruptcy,
insolvency, moratorium, receivership and other similar laws affecting the
enforcement of creditors' rights generally. Notwithstanding anything herein or
in any other document to the contrary, to the maximum extent provided in Section
3803(b) of the Statutory Trust Act, a trustee of the Trust, when acting in such
capacity, shall not be personally liable to any Person other than the Trust and
the beneficial owners thereof for any act, omission or obligation of the Trust
or any other trustee or other agent or representative of the Trust.

            In the exercise or administration of the trusts hereunder, the
Trustee (i) may act directly or, at the expense of the Trust, through agents or

trustee or separate trustees, of all or any part of the Trust, and to vest in
such Person or Persons, in such capacity and for the benefit of the Holders of
the Trust Preferred Securities, such title to the Trust, or any part thereof,

      imposed upon and exercised or performed by the Trustee shall be exercised
      or performed by the Trustee and such separate trustee or co-trustee
      jointly (it being understood that such separate trustee or co-trustee is
      not authorized to act separately without the Trustee joining in such act),
      except to the extent that under any laws of any jurisdiction in which any
      particular act or acts are to be performed, the Trustee shall be
      incompetent or unqualified to perform such act or acts, in which event,
      such rights, powers, duties and obligations (including the holding of
      title to the Trust or any portion thereof in any such jurisdiction) shall
      be exercised and performed singly by such separate trustee or co-trustee,
      but solely at the direction of the Trustee;

                  (ii)  the Trustee shall be personally liable by reason of any
      act or omission of any separate trustee or co-trustee; and

      remove any separate trustee or co-trustee.

            (c)   Any notice, request or other writing given to the Trustee

co-trustees, as effectively as if given to each of them. Every instrument
appointing any separate trustee or co-trustee shall refer to this Trust
Agreement. Each separate trustee and co-trustee, upon its acceptance of the
trusts conferred, shall be vested with the estates or property specified in its
instrument of appointment, either jointly with the Trustee or separately, as may
be provided therein, subject to all the provisions of this Trust Agreement,
specifically including every provision of this Trust Agreement relating to the
conduct of, affecting the liability of, or affording protection to, the Trustee.
Every such instrument shall be filed with the Trustee and a copy thereof given
to the Grantor.

            (d)   Any separate trustee or co-trustee may at any time constitute
the Trustee as its agent or attorney-in-fact with full power and authority, to
the extent not prohibited by law, to do any lawful act under or in respect to
this Trust Agreement on its behalf and in its name. If any separate trustee or
co-trustee shall die, become incapable of acting, resign or be removed, all of
its estates, properties, rights, remedies and trusts shall vest in and be
exercised by the Trustee, to the extent permitted by law, without the
appointment of a new or successor trustee.

duties of the Trustee and the Grantor. The statements made herein are summaries
of certain provisions of the Trust Agreement and are subject to the detailed
provisions thereof, to which reference is hereby made. In the event of any
conflict or discrepancy between the provisions hereof and the provisions of the
Trust Agreement, the provisions of the Trust Agreement shall govern. Unless
otherwise expressly herein provided, all defined terms used herein shall have
the meanings ascribed thereto in the Trust Agreement.

      (ii)  Enforcement of Rights; Withdrawal of Company Preferred Securities.
To the fullest extent permitted by law, without the need for any other action of
any Person, including the Trustee or any other Holder, each Holder shall be
entitled to enforce, in the name of the Trust, the rights of the Trust in
respect of the number of Company Preferred Securities and the Subordinated
Guarantee corresponding to the Trust Preferred Certificates held by such Holder.
Any recovery on such enforcement action shall belong solely to such Holder who
brought the action, not to the Trust, the Trustee or any other Holder
individually or to Holders as a group.

            Any beneficial owner of Trust Preferred Securities may withdraw all,
but not less than all, of the number of Company Preferred Securities
corresponding to such Trust Preferred Securities by providing a written notice
to the Trustee, with evidence of beneficial ownership in form satisfactory to
the Trustee, and providing to the Grantor such documents or information as the
Grantor may request for tax reporting purposes at the Corporate Office. Such
notice shall also be deemed to be such beneficial owner's agreement to be
subject to the terms of the LLC Agreement.

      (iii) Distributions of Dividends on Company Preferred Securities. Whenever
(and to the extent) the Trust receives any cash payment representing a Dividend
or redemption payment on the Company Preferred Securities, the Trustee acting
directly or through any Paying Agent shall distribute such amounts to Holders of
Trust Preferred Securities on the record date therefor, in proportion to the
respective liquidation amounts of the Trust Preferred Securities held by such
Holders.

      (iv)  Redemptions of Company Preferred Securities. The Trust Preferred
Securities shall be redeemed only upon redemption of the Company Preferred
Securities.

            If the Grantor redeems the Company Preferred Securities in
accordance with the LLC Agreement, then the Grantor shall give the Trustee at
least 30 days' prior notice before doing so. The Trustee shall mail the notice
of the redemption not less than 25 days prior to the date fixed for redemption
of the Company Preferred Securities to the Holders of the Trust Preferred
Securities. No defect in the notice of redemption or in the mailing or delivery
thereof or publication of its contents shall affect the validity of the
redemption proceedings.

            If only some of the outstanding Trust Preferred Securities are to be
redeemed, the Trust Preferred Securities to be redeemed shall be selected in
accordance with DTC's procedures. If the Trust Preferred Securities do not
remain registered in the name of DTC or its nominee and only some of the
outstanding Trust Preferred Securities are to be redeemed, the Trust Preferred
Securities shall be redeemed proportionally or selected for redemption pursuant
to the rules of any securities exchange on which the Trust Preferred Securities
are listed at that time. The Grantor shall promptly notify in writing the
Registrar and Transfer Agent for the Trust Preferred Securities of the Trust
Preferred Securities selected for redemption.

            On the date of redemption of the Company Preferred Securities, so
long as the Company or the Bank has deposited with the Paying Agent on behalf of
the Trust the aggregate amount payable upon redemption of all the Company
Preferred Securities held by the Trust to be redeemed, the Paying Agent on
behalf of the Trust shall irrevocably deposit with DTC funds sufficient to pay
the redemption price and give DTC irrevocable instructions to pay the redemption
price to the Holders of the Trust Preferred Securities to be redeemed.

      (v)   Distributions in Liquidation of Grantor. Upon receipt by the Trust
of any Liquidation Preference from the Grantor upon the liquidation of the
Grantor, after satisfaction of creditors of the Trust required by applicable
law, the Trust shall distribute the same to Holders of the Trust Preferred
Securities on the record date therefor, in proportion to the respective
Liquidation Preference of the number of Company Preferred Securities
corresponding to the Trust Preferred Securities held by such Holders.

      (vi)  Fixing of Record Date for Holders of the Trust Preferred Securities.
Each Regular Distribution on the Trust Preferred Securities shall be payable to
the Holders of record as they appear on the Register on the corresponding record
date. The record date for Regular Distributions is the fifteenth calendar day
prior to the relevant distribution date. Whenever any other distribution shall
become payable, or whenever the Trustee shall receive notice of any meeting at
which holders of the Company Preferred Securities are entitled to vote or of
which holders of the Company Preferred Securities are entitled to notice, the
Trustee shall in each such instance fix a record date (which shall be the same
date as the record date fixed by the Grantor with respect to the Company
Preferred Securities, of which the Grantor shall promptly inform the Trustee)
for the determination of the Holders of the Trust Preferred Securities who shall
be entitled (i) to receive such distribution or (ii) to receive notice of, and
to give instructions for the exercise of voting rights at, any such meeting.

                                      -3-

      (vii) Payment of Distributions. As long as the Trust Preferred Securities
are in book-entry form, payments on the Trust Preferred Securities shall be made
to DTC, which shall credit the relevant accounts at DTC on the scheduled payment
dates. The payments shall be distributed to participants, indirect participants
and beneficial owners of the Trust Preferred Securities in accordance with DTC's
procedures.

            If definitive Trust Preferred Securities are issued, payments on the
Trust Preferred Securities shall be made by check mailed to the address of the
Holder entitled to receive the payment, as address appears in the Register.
Payments of the redemption price of, and distributions in liquidation on, Trust
Preferred Securities shall be made upon surrender of such Trust Preferred
Securities at the office of the Paying Agent.

      (viii) Voting Rights. If at any time, the holders of Company Preferred
Securities are entitled to vote under the LLC Agreement, the Trustee shall: (i)
notify the Holders of the Trust Preferred Securities of such right, (ii) request
specific direction from each Holder as to the vote with respect to the Company
Preferred Securities represented by such Holder's Trust Preferred Securities,
and (iii) vote the relevant Company Preferred Securities only in accordance with
such specific direction.

            Upon receiving notice of any meeting at which the holders of Company
Preferred Securities are entitled to vote, the Trustee shall, as soon as
practicable, mail to the Holders of the Trust Preferred Securities a notice. The
Company shall provide the form of notice to the Trustee to be forwarded to the
Holders of the Trust Preferred Securities. The notice shall contain: (i) all the
information that is contained in the notice announcing the meeting of the
Company Preferred Securities, (ii) a statement that the Holders of the Trust
Preferred Securities shall be entitled, subject to any applicable provision of
law, to direct the Trustee specifically as to the exercise of the voting rights
pertaining to the number of the Company Preferred Securities represented by
their respective Trust Preferred Securities, and (iii) a brief description of
the manner in which the Holders of the Trust Preferred Securities may give such
specific directions.

            If the Trust receives a written direction from a Holder, the Trustee
shall vote, or cause to be voted, the amount of the Company Preferred Securities
represented by such Holder's Trust Preferred Securities in accordance with the
instructions set forth in the directions. If the Trustee does not receive
specific instructions from any Holder, the Trustee shall abstain from voting the
Company Preferred Securities represented by such Holder's Trust Preferred
Securities.

      (ix)  Currency. All distribution and other payments and all other monetary
rights and obligations in respect of the Trust Preferred Certificates shall be
performed in U.S. dollars.

      (x)   Transfer and Exchange of Trust Preferred Securities. Subject to the
terms and conditions of the Trust Agreement, the Registrar shall register the
transfers on the Register from time to time of Trust Preferred Securities upon
any surrender thereof by the Holder in person or by a duly authorized attorney,
properly endorsed or accompanied by a properly executed instrument of transfer
or endorsement, together with evidence of the payment of any transfer taxes as
may be required by law. Upon such surrender, the Trustee shall execute a new
Trust

                                      -4-
<PAGE>
Preferred Security representing the same corresponding amount of the Company
Preferred Securities and deliver the same to or upon the order of the Person
entitled thereto.

            Upon surrender of a Trust Preferred Security at the office of the
Registrar or such other office as the Trustee may designate for the purpose of
effecting an exchange of Trust Preferred Securities, subject to the conditions
to transfer set forth in the Trust Agreement, the Trustee shall execute and
deliver a new Trust Preferred Security representing the same corresponding
amount of Company Preferred Securities as the Trust Preferred Security
surrendered.

            As a condition precedent to the registration of the transfer or
exchange of any Trust Preferred Security, the Registrar, may require (i) the
production of proof satisfactory to it as to the identity and genuineness of any
signature; (ii) compliance with such regulations, if any, as the Trustee or the
Registrar may establish not inconsistent with the provisions of the Trust
Agreement; and (iii) such other information as the Registrar may reasonably
request.

            No Holder may require the transfer of any Trust Preferred Security
to be registered during the period of fifteen days ending on the due date for
any payment of the Liquidation Preference on the Trust Preferred Securities. The
trust shall not be required to register, or cause others to register, the
transfer of Trust Preferred Securities after such Trust Preferred Securities
have been called for redemption.

      (xi)  Title to Trust Preferred Securities. It is a condition of the Trust
Preferred Securities, and every successive Holder hereof by accepting or holding
the same consents and agrees, that title to this Trust Preferred Security, when
properly endorsed or accompanied by a properly executed instrument of transfer
or endorsement, is transferable by delivery with the same effect as in the case
of a negotiable instrument; provided, however, that until the transfer of this
Trust Preferred Security shall be registered on the books of the Trust, the
Trustee, the Registrar and the Grantor may, notwithstanding any notice to the
contrary, treat the Holder hereof at such time as the absolute owner hereof for
the purpose of determining the Person entitled to distributions or to any notice
provided for in the Trust Agreement and for all other purposes.

      (xii) Reports, Inspection of Transfer Books. The Trustee shall make
available for inspection by Holders of the Trust Preferred Securities at the
Corporate Office and at such other places as it may from time to time deem
advisable during normal business hours any reports and communications received
by the Trustee as the record holder of the Company Preferred Securities. The
Registrar shall keep books at the Corporate Office for the registration of
transfer of Trust Preferred Securities, which books at all reasonable times
shall be open for inspection by the Holders of the Trust Preferred Securities as
and to the extent provided by applicable law.

      (xiii) Supplemental Trust Agreement. The Grantor and the Trustee may, at
any time and from time to time, without the consent of the Holders of the Trust
Preferred Securities, enter into one or more agreements supplemental to the
Trust Agreement, in form satisfactory to the Trustee, for any of the following
purposes: (a) to evidence the succession of another partnership, corporation or
other entity to the Grantor and the assumption by any such successor

                                      -5-
<PAGE>
of the covenants of the Grantor contained therein; (b) to add to the covenants
of the Grantor for the benefit of the Holders of the Trust Preferred Securities,
or to surrender any right or power herein conferred upon the Grantor; (c)(i) to
correct or supplement any provision therein which may be defective or
inconsistent with any other provision therein or (ii) to make any other
provisions with respect to matters or questions arising under the Trust
Agreement, provided that any such action taken under subsection (ii) hereof
shall not materially adversely affect the interests of the Holders of the Trust
Preferred Securities; or (d) to cure any ambiguity or correct any mistake. Any
other amendment or agreement supplemental hereto must be in writing and approved
by Holders of 66 2/3% of the then outstanding Trust Preferred Securities.

      (xiv) Governing Law. The Trust Agreement and this Trust Preferred Security
and all rights thereunder and hereunder and provisions thereof and hereof shall
be governed by, and construed in accordance with, the law of the State of
Delaware.

      (xv)  Trust Preferred Security Non-Assessable and Fully Paid. Holders of
the Trust Preferred Securities shall not be personally liable for obligations of
the Trust, the interest in the Trust represented by the Trust Preferred
Securities shall be non-assessable for any losses or expenses of the Trust or
for any reason whatsoever and the Trust Preferred Securities upon delivery
thereof by the Trustee pursuant to the Trust Agreement are and shall be deemed
fully paid.

      (xvi) Liability of Holders of the Trust Preferred Securities. Holders of
the Trust Preferred Securities shall be entitled to the same limitation of
personal liability extended to stockholders of private corporations for profit
organized under the General Corporation Law of the State of Delaware.

      (xvii) No Preemptive Rights. No Holder shall be entitled as a matter of
right to subscribe for or purchase, or have any preemptive right with respect
to, any part of any new or additional interest in the Trust, whether now or
hereafter authorized and whether issued for cash or other consideration or by
way of distribution.

            This Trust Preferred Security shall not be entitled to any benefits
under the Trust Agreement or be valid or obligatory for any purpose unless this
Trust Preferred Security shall have been executed by the Trustee by the manual
signature of a duly authorized signatory of the Trustee, provided, however, that
such signature may be a facsimile if a Registrar (other than the Trustee) shall
have countersigned this Security by manual signature of a duly authorized
signatory of the Registrar.

PREFERRED SECURITIES. THE TRUSTEE ASSUMES NO RESPONSIBILITY FOR THE CORRECTNESS
OF THE FOREGOING DESCRIPTION WHICH CAN BE TAKEN AS A STATEMENT OF THE GRANTOR
