                  2.5.1 Conversion of Legacy Common Stock.

                  At the Effective Time the conversion of each outstanding share
of Legacy Common Stock shall proceed as follows:

                        (a)      Subject to the exceptions and limitations in
Section 2.5.1(b), each outstanding share of Legacy Common Stock shall, without
any further action on the part of Legacy or the holders of any such shares, be
converted into the right to receive shares of Bancshares Common Stock in
accordance with the Exchange Ratio.

                        (b)      Certain Exceptions and Limitations. (A) Legacy
Perfected Dissenting Shares shall not be converted into the right to receive
shares of Bancshares Common Stock, but shall, after the Effective Time, be
entitled only to such rights as are granted them by Section 214a of the NBA
(each dissenting shareholder who is entitled to payment for his shares of Legacy
Common Stock shall receive such payment in an amount as determined pursuant to
Section 214a of the NBA), and (B) no fractional shares of Bancshares Common
Stock shall be issued in the Merger and, in lieu thereof, each holder of Legacy
Common Stock who would otherwise be entitled to receive a fractional share shall
receive an amount in cash equal to the product (calculated to eight places)
obtained by multiplying such fractional share interest by the Average Closing
Price.

                        (c)      The holders of certificates formerly
representing shares of Legacy Common Stock shall cease to have any rights as
shareholders of Legacy, except such rights, if any, as they may have pursuant to
national banking laws. Except as provided above, until certificates representing
shares of Legacy Common Stock are surrendered for exchange, the certificates of
each holder shall, after the Effective Time, represent for all purposes only the
right to receive shares of Bancshares Common Stock in accordance with the
Exchange Ratio.

                  2.5.2 Reservation of Shares. Prior to the Effective Time, the
Board of Directors of Bancshares shall reserve for issuance a sufficient number
of shares of Bancshares Common Stock for the purpose of issuing its shares to
the shareholders of Legacy in accordance herewith.

                  2.5.3 Exchange of Legacy Common Stock.

                        (a)      As soon as reasonably practicable after the
Effective Time, holders of record of certificates formerly representing shares
of Legacy Common Stock ("Certificates") shall be instructed to tender such
Certificates to the Exchange Agent pursuant to a letter of transmittal that
Bancshares shall deliver or cause to be delivered to such holders. Such letter
of transmittal shall specify that risk of loss and title to Certificates shall
pass only upon acceptance of such Certificates by Bancshares or the Exchange
Agent.

                        (b)      After the Effective Time, each holder of a
Certificate that surrenders such Certificate to Bancshares or the Exchange Agent
will, upon acceptance thereof by Bancshares or the Exchange Agent, be entitled
to receive shares of Bancshares Common Stock in accordance with Section 2.5.1
hereof.

                        (c)      Bancshares or the Exchange Agent shall accept
Certificates upon compliance with such reasonable terms and conditions as
Bancshares or the Exchange Agent may impose to effect an orderly exchange
thereof in accordance with customary exchange practices. Certificates shall be
appropriately endorsed or accompanied by such instruments of transfer as
Bancshares or the Exchange Agent may reasonably require.

<PAGE>

                        (d)      Each outstanding Certificate, other than those
representing Perfected Dissenting Shares, shall until duly surrendered to
Bancshares or the Exchange Agent be deemed to evidence the right to receive
shares of Bancshares Common Stock in accordance with Section 2.5.1 hereof.

                        (e)      After the Effective Time, holders of
Certificates shall cease to have rights with respect to the Legacy Common Stock
previously represented by such Certificates, and their sole rights (other than
the holders of Certificates representing Perfected Dissenting Shares) shall be
to exchange such Certificates for shares of Bancshares Common Stock in
accordance with Section 2.5.1 hereof. At the Effective Time, Legacy shall
deliver a certified copy of a list of its shareholders to Bancshares or the
Exchange Agent. After the Effective Time, there shall be no further transfer of
Certificates on the records of Legacy, and if such Certificates are presented to
Legacy for transfer, they shall be canceled against delivery of the shares of
Bancshares Common Stock in accordance with Section 2.5.1 hereof. Bancshares
shall not be obligated to deliver any shares of Bancshares Common Stock to any
holder of Legacy Common Stock until such holder surrenders the Certificates as
provided herein. No dividends declared will be remitted, nor any voting rights
granted, to any person entitled to receive Bancshares Common Stock under this
Agreement until such person surrenders the Certificate representing the right to
receive such Bancshares Common Stock, at which time such dividends on whole
shares of Bancshares Common Stock with a record date on or after the Effective
Time shall be remitted to such person, without interest and less any taxes that
may have been imposed thereon, and voting rights will be restored. Certificates
surrendered for exchange by any person constituting an "affiliate" of Legacy for
purposes of Rule 145 under the Securities Act shall not be exchanged for
certificates representing Bancshares Common Stock until Bancshares has received
a written agreement from such person as specified in Section 5.3. Neither the
Exchange Agent nor any party to this Agreement nor any affiliate thereof shall
be liable to any holder of Legacy Common Stock represented by any Certificate
for any consideration paid to a public official pursuant to applicable abandoned
property, escheat or similar laws. Bancshares and the Exchange Agent shall be
entitled to rely upon the stock transfer books of Legacy to establish the
identity of those persons entitled to receive consideration specified in this
Agreement, which books shall be conclusive with respect thereto. In the event of
a dispute with respect to ownership of stock represented by any Certificate,
Bancshares or the Exchange Agent shall be entitled to deposit any consideration
in respect thereof in escrow with an independent third party or with a court of
competent jurisdiction and thereafter be relieved with respect to any claims
thereto.

                        (f)      If any shares of Bancshares Common Stock are to
be issued to a person other than a person in whose name a surrendered
Certificate is registered, it shall be a condition of issuance that the
surrendered Certificate shall be properly endorsed or otherwise in proper form
for transfer and that the person requesting such issuance shall pay to
Bancshares or the Exchange Agent any required transfer or other taxes or
establish to the satisfaction of Bancshares or the Exchange Agent that such tax
has been paid or is not applicable.

                        (g)      In the event any Certificate shall have been
lost, stolen or destroyed, the owner of such lost, stolen or destroyed
Certificate shall deliver to Bancshares or the Exchange Agent an affidavit
stating such fact, in form satisfactory to Bancshares, and, at Bancshares'
discretion, a bond in such reasonable sum as Bancshares or the Exchange Agent
may direct as indemnity against any claim that may be made against Bancshares or
Legacy or its successor or any other party with respect to the Certificate
alleged to have been lost, stolen or destroyed. Upon such delivery, the owner
shall have the right to receive the shares of Bancshares Common Stock in
accordance with Section 2.5.1 hereof with respect to the shares represented by
the lost, stolen or destroyed Certificate.

                  2.5.4 Cancellation of Legacy Stock Options and Warrants.
Immediately prior to the Effective Time, each outstanding Legacy Stock Option
and each outstanding Legacy Warrant will be cancelled and each optionee and
warrantholder, as applicable, will receive payment by Legacy in an amount equal
to (i) the difference between the Merger Consideration and the underlying
exercise price of the Legacy Stock Option, or Legacy Warrant, as applicable,
multiplied by (ii) the number of shares underlying the Legacy Stock Option, or
Legacy Warrant, as applicable.

         2.6 Dissenters' Rights. Shares of Legacy Common Stock, the holders of
             ------------------
which have lawfully dissented from the Merger in accordance with Section 214a of
the NBA and have timely filed with USB a written demand for purchase of his or
her shares and have surrendered his or her stock certificates pursuant to
paragraph (b) of Section 214a of the NBA, are herein called "Dissenting Shares."
Dissenting Shares, the holders of which have not effectively withdrawn or lost
their dissenters' rights under paragraph (b) of Section 214a of the NBA
("Perfected Dissenting Shares"), shall not be converted pursuant to Section 2.5
but the holders thereof shall be entitled only to such rights as are granted by
paragraph (b) of Section 214a of the NBA. Each holder of Perfected Dissenting
Shares who is entitled to payment for his or her Legacy Common Stock pursuant to
the provisions of paragraph (b) of Section 214a of the NBA shall receive payment
therefore from USB (but only after the amount thereof shall have been agreed
upon or finally determined pursuant to such provisions).

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

Closing of the Merger is not materially delayed.

Schedule 3.15, Legacy has performed all material obligations required to be
performed by it to date and Legacy is not in material default under or in breach
of any term or provision of any covenant, contract, lease, indenture or any
other agreement, written or oral, to which any is a party, is subject or is
otherwise bound, and no event has occurred that, with the giving of notice or
the passage of time or both, would constitute such a default or breach, where
such default or breach or failure to perform would have a Material Adverse
Effect on Legacy. To the Knowledge of Legacy, and except as disclosed on
Schedule 3.15 or in the portion of Schedule 3.16 that identifies 90-day past due
or classified or nonaccrual loans, no party with whom Legacy has an agreement
that is of material importance to the businesses of Legacy is in default there

         Section 3.16 Loans and Investments. Except as set forth on Schedule
                      ---------------------
3.16, all loans, leases and other extensions of credit, and guaranties, security
agreements or other agreements supporting any loans or extensions of credit, and
investments of Legacy are, and constitute, in all material respects, the legal,
valid and binding obligations of the parties thereto and are enforceable against
such parties in accordance with their terms, except as the enforceability
thereof may be limited by applicable law and otherwise by bankruptcy,
liquidation, receivership, conservatorship, insolvency, moratorium or other
similar laws affecting the rights of creditors generally and by general
equitable principles. Except as described on Schedule 3.16, as of September 30,
2006, no loans or investments held by Legacy are: (i) more than ninety (90) days
past due with respect to any scheduled payment of principal or interest, other
than loans on a nonaccrual status; (ii) classified as "loss," "doubtful,"
"substandard" or "specially mentioned" by Legacy or any banking regulators; or
(iii) on a nonaccrual status in accordance with Legacy's loan review procedures.
Except as set forth on Schedule 3.16, none of such assets (other than loans) are
subject to any restrictions, contractual, statutory or other, that would
materially impair the ability of the entity holding such investment to dispose
freely of any such assets at any time, except restrictions on the public
distribution or transfer of any such investments under the Securities Act and
the regulations there under or state securities laws and pledges or security
interests given in connection with government deposits. All loans, leases or
other extensions of credit outstanding, or commitments to make any loans, leases
or other extensions of credit made by Legacy to any Affiliates of Legacy are
disclosed on Schedule 3.16. For outstanding loans or extensions of credit where
the original principal amounts are in excess of $100,000 and which by their
terms are either secured by collateral or supported by a guaranty or similar
obligation, the security interests have been duly perfected in all material
respects and have the priority they purport to have in all material respects,
other than by operation of law, and, in the case of each guaranty or similar
obligation, each has been duly executed and delivered to Legacy and to Legacy's
Knowledge, is still in full force and effect.

reflected and disclosed in the Legacy Financial Statements or on Schedule 3.20.

Legacy or any of its Affiliates and or relating to, any of their employees that

is not a party to any collective bargaining agreement with respect to any of
their employees and, except as set forth on Schedule 3.21.1, Legacy is not a
party to a written employment contract with any of its employees and there are
no understandings with respect to the employment of any officer or employee of

Arrangement (as defined in Section 3.21.4 hereof) have been duly and adequately
paid or provided for in accordance with plan documents. Except as set forth on
Schedule 3.21.1, no director, officer or employee of Legacy is entitled to

or other benefit plan as a result of the consummation of any transaction
contemplated by this Agreement or the Merger Agreement. To Legacy's Knowledge,
Legacy has materially complied with all applicable federal and state statutes
and regulations which govern workers' compensation, equal employment opportunity
and equal pay, including, but not limited to, all civil rights laws,
Presidential Executive Order 1124, the Fair Labor Standards Act of 1938, as

                         (a)     All current employees of Legacy together with

annual rate of compensation anticipated to be paid to each such employee; and

                         (b)     All Employee Plans and Benefit Arrangements,
including all plans or practices providing for current compensation or accruals
for active employees, including, but not limited to, all employee benefit plans,
all pension, profit-sharing, retirement, bonus, stock option, incentive,

hospitalization, life insurance or other insurance plans or related benefits.

                  3.21.3 Except as disclosed on Schedule 3.21.3, Legacy does not
maintain, administer or otherwise contribute to any "employee benefit plan," as
defined in Section 3(3) of ERISA, which is subject to any provisions of ERISA
and covers any employee, whether active or retired, of Legacy or any of its
Subsidiaries (any such plan being herein referred to as an "Employee Plan").
True and complete copies of each such Employee Plan, including amendments
thereto, have been previously delivered or made available to Bancshares,
together with (i) all agreements regarding plan assets with respect to such
Employee Plans, (ii) a true and complete copy of the annual reports for the most
recent three years (Form 5500 Series including, if applicable, Schedules A and B

complete copy of the actuarial valuation reports for the most recent three
years, if any, prepared in connection with any such Employee Plan covering any

and Legacy has not been obligated to make a contribution to any such
multiemployer or multiple employer plan within the past five years. None of the

Section 401(a) of the IRC is so qualified and each trust maintained pursuant
thereto is exempt from income tax under Section 501(a) of the IRC, and Legacy is
not aware of any fact which has occurred that would cause the loss of such
qualification or exemption.

                  3.21.4 Except as disclosed in Schedule 3.21.4, Legacy does not
maintain (other than base salary and base wages) any form of current or deferred
compensation, bonus, stock option, stock appreciation right, severance pay,
salary continuation, retirement or incentive plan or arrangement for the benefit
of any director, officer or employee, whether active or retired, of Legacy or
for any class or classes of such directors, officers or employees. Except as
disclosed in Schedule 3.21.4, Legacy does not maintain any group or individual
health insurance, welfare or similar plan or arrangement for the benefit of any
director, officer or employee of Legacy, whether active or retired, or for any
class or classes of such directors, officers or employees. Any such plan or
arrangement described in this Section 3.21.4, copies of which have been
delivered or made available to Bancshares, shall be herein referred to as a
"Benefit Arrangement."

                  3.21.5 To Legacy's Knowledge, all Employee Plans and Benefit
Arrangements are operated in material compliance with the requirements
prescribed by any and all statutes, governmental or court orders, or
governmental rules or regulations currently in effect, including but not limited
to ERISA and the IRC, applicable to such plans or arrangements, and plan
documents relating to any such plans or arrangement, materially comply with or
will be amended to materially comply with applicable legal requirements. Neither
Legacy, nor any Employee Plan nor any trusts created there under, nor any
trustee, administrator nor any other fiduciary thereof has engaged in a
"prohibited transaction," as defined in Section 406 of ERISA and Section 4975 of
the IRC, that could subject Legacy or Bancshares to liability under Section 409
or 502(i) of ERISA or Section 4975 of the IRC or that would adversely affect the
qualified status of such plans; each "plan official" within the meaning of
Section 412 of ERISA of each Employee Plan is bonded to the extent required by
such Section 412; with respect to each Employee Plan, to Legacy's Knowledge, no
employee of Legacy, nor any fiduciary of any Employee Plan, has engaged in any
breach of fiduciary duty as defined in Part 4 of Subtitle B of Title I of ERISA
which could subject Legacy or any of its Subsidiaries to liability if Legacy or
any such Subsidiary is obligated to indemnify such Person against liability.
Except as disclosed in Schedule 3.21.5, Legacy has not failed to make any
material contribution or pay any amount due and owing as required by law or the
terms of any Employee Plan or Benefit Arrangement.

Plan or Benefit Arrangement has any material liability of any nature, accrued or
contingent, including, without limitation, liabilities for federal, state, local
or foreign taxes, interest or penalty other than liability for claims arising in
the course of the administration of each such Employee Plan. Except as set forth
on Schedule 3.21.6, to Legacy's Knowledge there is no pending or threatened
legal action, proceeding or investigation against any Employee Plan that could
result in material liability to such Employee Plan, other than routine claims
for benefits, and there is no basis for any such legal action, proceeding or
investigation.

                  3.21.7 To Legacy's Knowledge, each Benefit Arrangement which

employee of Legacy or Affiliate thereof, in either case as a result of the
consummation of the transactions contemplated by this Agreement or the Merger
Agreement.

         Section 6.3 Affirmative Conduct of Bancshares. During the period from
                     ---------------------------------
the date of execution of this Agreement through the Effective Time, Bancshares
shall carry on its business in a reasonable manner consistent with applicable
laws and use all commercially reasonable efforts to preserve intact its business
organization and preserve its relationships with customers; and, to these ends,
shall fulfill each of the following:

                  6.3.1 Use its commercially reasonable efforts, or cooperate
with others, to expeditiously bring about the satisfaction of the conditions
specified in Article 7 hereof;

                  6.3.2 Advise Legacy promptly in writing of any change that
would have a Material Adverse Effect on it or of any matter which would make the
representations and warranties set forth in Article 4 hereof not true and
correct in any material respect as of the effective date of the Registration
Statement and at the Effective Time;

                  6.3.3 Duly observe and conform to all legal requirements
applicable to its business, except for any failure to so observe and conform
that would not, individually or in the aggregate, and, in the future will not,
have a Material Adverse Effect on Bancshares or USB;

                  6.3.4 Duly and timely file as and when due all material
regulatory reports and Returns required to be filed with any Governmental
Entity;

                  6.3.5 File all necessary applications with the OCC, Federal

present the financial position of Bancshares during the periods involved to
which it relates will fairly present in all material respects the financial
position of Bancshares and will be prepared in accordance with GAAP or
consistent with applicable regulatory accounting principles and banking law and
banking regulations, except as stated therein;

                  6.3.7 Insurance.

                        (a)   Bancshares and USB shall permit Legacy to use
commercially reasonable efforts to (i) extend the discovery period of its
directors' and officers' liability insurance for a period of up to 48 months
with respect to all matters arising from facts or events which occurred before
the Effective Time for which Legacy would have had an obligation to indemnify
its directors and officers or (ii) buy "peace of mind" coverage from the
California Bankers' Association; provided, however, that the total costs to
Legacy, Bancshares and USB of the premiums for either of such alternatives shall
not exceed $50,000. If Legacy is unable to maintain or obtain the insurance
called for by this Section 6.3.7 as a result of the preceding provision, Legacy
shall use commercially reasonable efforts to obtain as much comparable insurance
as is available for $50,000 with respect to acts or omissions occurring prior to
the Effective Time of the Merger by such directors and officers in their
capacities as such. If Bancshares shall consolidate with or merge into any other
entity and shall not be the continuing or surviving entity of such consolidation
or merger or shall transfer all or substantially all of its assets to any other
entity, then and in each case, proper provision shall be made so that the
successors and assigns of Bancshares shall assume the obligations set forth in
this Section 6.3.7. The provisions of the penultimate sentence of this Section
are intended to be for the benefit of each director or officer of Legacy and
shall be enforceable by such director or officer and his or her heirs and
representatives.

                        (b)   For a period of four years after the Effective
Time, Bancshares shall, and shall cause its subsidiaries to, maintain and
preserve the rights to indemnification of officers and directors provided for in
the Articles of Association and Bylaws of Legacy, or any indemnification
agreement, as in effect on the date hereof with respect to indemnification for
liabilities and claims arising out of acts, omissions, events, matters or
circumstances occurring or existing prior to the Effective Time, including,
without limitation, the Merger and the other transactions contemplated by this
Agreement, to the extent such rights to indemnification are not in excess of
that permitted by applicable state or federal laws or regulatory authorities.

                        (c)   The provisions of this Section are intended to be
for the benefit of, and shall be enforceable by, each director or officer of
Legacy and his or her heirs and representatives.

                  6.3.8 Rule 144 Compliance. From and after the Effective Time
of the Merger, Bancshares shall file timely all reports with the SEC necessary
to permit the shareholders of Legacy who may be deemed "underwriters" (within
the meaning of Rule 145 under the Securities Act) of Legacy Common Stock to sell
Bancshares Common Stock received by them in connection with the Merger pursuant
to Rules 144 and 145(d) under the Securities Act if they would otherwise be so
entitled; provided, however, that Bancshares is otherwise obligated to file such
reports with the SEC.

                  6.3.9 Blue Sky. Bancshares agrees to use commercially
reasonable efforts to have the shares of Bancshares Common Stock to be issued in
connection with the Merger qualified or registered for offer and sale, to the
extent required, under the securities laws of each jurisdiction in which
shareholders of Legacy reside.

this Agreement such number of shares of Bancshares Common Stock to be issued to
the shareholders of Legacy in the Merger pursuant to Article 2 hereof.

                  6.3.11 Nasdaq Listing. Bancshares shall use its commercially
reasonable efforts to cause the shares of Bancshares Common Stock to be issued
in the Merger to be approved for quotation on the Nasdaq National Market System,
subject to official notice of issuance, prior to the Effective Time of the
Merger.

                  6.3.12 Compliance with Rules. Bancshares and USB shall comply
with the requirements of all applicable Rules, the noncompliance with which
would have a Material Adverse Effect on the assets, liabilities, business,
financial condition or results of operations or prospects of Bancshares and USB.

                  6.3.13 Agreement of Merger. As soon as practicable, Bancshares
and USB shall execute the Agreement of Merger.

                  6.3.14 Legacy Employees. Within seventy-five (75) days from
the date of this Agreement, Bancshares shall provide written notice to Legacy of
Bancshares' intentions with regard to its retention of Legacy employees.
Bancshares shall use its best efforts to retain (whether through reassignment or
otherwise) Legacy employees, and in particular shall retain all branch and loan
center personnel.

                  6.3.15 Approval by Bancshares. In its capacity as the sole
shareholder of USB, Bancshares shall formally approve this Agreement and further
agreements and transactions contemplated by this Agreement. Such approval shall
be granted by vote at a properly convened meeting of the sole shareholder of USB
or by unanimous written consent.

                     --------------------------------
the date of execution of this Agreement through the Effective Time, except as
contemplated by this Agreement, and subject to requirements of law and
regulation generally applicable to banks, Bancshares shall not, without Legacy's
prior written consent (which consent shall not be unreasonably withheld and
which consent shall be deemed granted if within five (5) Business Days of
Legacy's receipt of written notice of a request for prior written consent,
written notice of objection is not received by Bancshares):

                  6.4.1 Declare, issue or pay any dividend or other distribution
of assets, whether consisting of money, other personal property, real property
or other things of value, to the shareholders of Bancshares, or split, combine
or reclassify any shares of its capital stock, Bancshares Common Stock, or other
Equity Securities of Bancshares, except for cash dividends payable by Bancshares
to its shareholders in accordance with past practice;

                  6.4.2 Take any action that would or might result in any of the
representations and warranties of Bancshares or USB set forth in the Agreement
becoming untrue in any material respect or any of the conditions to the Merger
set forth in Article 7 not being satisfied or otherwise materially delay or
impair completion of the Merger, except to the extent such actions are required
to be undertaken by applicable law, regulation or at the direction of any
Regulatory Authority;

disqualify the Merger as a "reorganization" within the meaning of Section 368(a)
of the IRC as a tax-free reorganization;

                  6.4.4 Change its fiscal year or methods of accounting in
effect at December 31, 2005, except as required by changes in GAAP or regulatory
accounting principles as concurred to by Bancshares' independent public
accountants or by Section 5.8 of this Agreement; or

                  6.4.5. Take any action which would or is reasonably likely to
(i) adversely affect the ability of Bancshares or USB to obtain any necessary
approval of any Governmental Entity required for the transactions contemplated
hereby; (ii) adversely affect Bancshares' or USB's ability to perform their
covenants and agreements under this Agreement; or (iii) result in any of the
conditions to the performance of Bancshares' or USB's obligations hereunder, as
set forth in Article 7 herein, not being satisfied

         Section 6.5  Access to Operations and Employees.
                      ----------------------------------

                  6.5.1 Within fifteen (15) Business Days of the Closing Date,
Legacy shall afford to USB and its authorized agents and representatives,
access, during normal business hours, to the operations, books, and other
information relating to Legacy for the sole purpose of assuring an orderly
transition of operations, including the data processing conversion, in the
Merger. USB shall give reasonable notice for access to Legacy, and the date and
time of such access with then be mutually agreed to by USB and Legacy. USB's
access shall be conducted in a manner which does not unreasonably interfere with
Legacy's normal operations, customers and employee relations and which does not
interfere with the ability of Legacy to consummate the transactions contemplated
by this Agreement.

                  6.5.2 USB shall have the right, but not the obligation, within
fifteen (15) Business Days of the Closing Date, to provide training to employees
of Legacy who will become employees of USB. Such training shall be at the
expense of USB and shall be conducted during normal business hours, or, if the
foregoing is not possible, after business hours at a location reasonably
requested by USB. At the request of USB, USB shall compensate employees, in
accordance with Legacy's customary policies and practices, for the employee's
time spent being trained by USB. Legacy shall cooperate with USB to make such
employees available for such training prior to the Closing. Training shall not
exceed 40 hours per employee. All travel and other reimbursable expense incurred
by the employee for training are USB's responsibility. Nothing in this Section
6.5.2 is intended, nor shall it be construed, to confer any rights or benefits
upon any persons other than USB, Bancshares or Legacy.

that reorganization within the meaning of Section 368(b) of the IRC;

                     ---------------------
shall be terminated pursuant to Section 8.1 hereof, all further obligations of

hereof, the conditions that are unsatisfied immediately prior to the Effective

such Party under this Agreement, neither Party shall be obligated to the other
Party to this Agreement for any expenses or otherwise be liable hereunder.
