Thousand Dollars ($260,000) payable monthly in arrears or by such manner as may
be established by Holding Co. or Bank from time to time but not less often than

nature whatsoever with regard to such automobile, provided Executive furnishes
to the Holding Co. or Bank adequate records and other documentary evidence

appropriate taxing authorities for substantiation of such payments as
deductible business expenses of the Holding Co. or Bank and not as deductible
compensation to Executive.  The Holding

insurance policy on such automobile, containing all reasonable and necessary
coverage.  Executive will maintain a
record of personal use mileage, which will be reflected on Executives W-2 in
accordance with IRS guidelines.  4.3           Medical, Dental and Life Insurance.  Holding Co. and Bank will provide Executive

and Bank in obtaining any key man or other insurance coverage Holding Co. and
Bank may reasonably desire.  4.4           Business Expenses.  In accordance with Holding Co. and Bank

such expenses by the Board of Directors of Holding Co. or Bank, Executive shall
be entitled to reimbursement by Holding Co. or Bank for any ordinary,
reasonable business expenses incurred by Executive in the performance of
Executives duties and in acting for Holding Co. or Bank during the term of
this Agreement, provided that Executive furnishes to Holding Co. or Bank
substantially adequate records and other documentary evidence as required by
Holding Co.s or Banks policies or by federal and state statutes and
regulations with respect to the substantiation of such expenditures as
deductible business expenses of Holding Co. or Bank.  4.5           Vacation.  Executive shall be entitled to four weeks of vacation per year

year.  Executive shall not be entitled
to vacation pay in lieu of vacation and accrual of any unused vacation time
shall be limited to a maximum of five (5) weeks at any time.  4.6           Stock Options.  The Holding Co. shall grant Executive a
stock option to purchase up to Thirty Thousand (30,000) shares of the Holding
Co.s authorized but unissued Common Stock (in addition to any currently outstanding
options held by Executive), at an exercise price equal to the market value on
the date of grant, subject to compliance with any applicable requirements of
the Holding Co.s Stock Option Plan. 
The Holding Co. and Executive agree that such option shall be for a term
of ten (10) years, and will vest over a period of five (5) years from the date
of grant as follows: twenty percent (20%) will be exercisable on or after each
of the first five anniversaries of the date of grant of the stock option.  The Holding Co. and Executive also   4 
   agree that, to the maximum extent permitted by
law, the option will qualify as an incentive stock option within the meaning
of Section 422 of the Internal Revenue Code of 1986, as amended.  Such stock option will be granted to
Executive pursuant to Holding Co.s current Stock Option Plan, and an agreement
between Holding Co. and Executive containing such terms as (i) are consistent with
the terms of the Stock Option Plan and (ii) may be agreed upon by such parties.  4.7           401 (k) Plan.  Executive shall be entitled to participate in the Banks or
Holding Companys 401 (k) Plan subject to the eligibility and vesting
requirements set forth in said Plan.  4.8           Executives Bonus.  In addition to the base salary provided for
in Section 4.1, Executive shall be paid, within thirty-one days following the
end of the Holding Co.s fiscal year, an amount equal to one percent (1%) of
Holding Co.s consolidated pre-tax income for such fiscal year; provided,
however, that such payment shall only be made if Holding Co.s return on
beginning Capital during such fiscal year equals or exceeds ten percent (10%);
and provided further that the Board of Directors of Holding Co. shall have the
discretion to either (i) reduce or eliminate the amounts payable to Executive
pursuant to this Section 4.8 in the event the Board determines in good faith
that the amount payable to Executive violates regulatory directives or orders
specifically applicable to Bank or Holding Company, or (ii) increase the amount
payable to Executive pursuant to this Section 4.8.  Calculation of Holding Co.s consolidated pre-tax income shall be
based on Holding Co.s year end audited financial statements prepared by
Holding Co.s certified public accountants, except as follows:  (a)           the calculation shall exclude Holding
Co.s and Banks accrual for bonuses;  (b)           the calculation shall include
recognized gains or losses in Holding Co.s
and Banks investment portfolios; and   5 
   (c)           the calculation shall include for
each fiscal year an amount equal to the portion of the Banks allowance for
loan losses (ALLL) which exceeds the greater of:  (i) 
one percent (1%) of the Banks total gross loans for the applicable
fiscal year;  (ii)  the amount calculated by the method set
forth as Test #1 on Exhibit A; or, (iii) 
the amount calculated by the method set forth as Test #2 on Exhibit A; provided,
however, that notwithstanding the above, Executive shall not be paid any bonus
with respect to amounts in the ALLL as to which a bonus was paid in previous
years; provided, further, that in the event the Banks ALLL for a fiscal
year is less than the greater of any of the methods set forth in
subparagraphs (i), (ii), or (iii), above, the difference between the two
amounts shall be excluded from pre-tax income.  In the event that
Executive is employed by Holding Co. and Bank for less than all of a fiscal
year, the bonus provided for herein shall be prorated.  5.             Termination; Liability.       Executives employment hereunder may be
terminated as follows:  5.1           Without Cause.  In the sole and absolute discretion of the
Board for any cause or for no cause whatsoever; provided, however, that if such
termination occurs and is for any cause other than as more particularly
described in Sections 5.2, 5.3 or 5.4 hereof, Executive shall receive within
ten (10) days of such termination a severance payment in an amount equal to the
monthly amount of base salary that would be payable multiplied by twenty-four
(24) months calculated at Executives then current base salary.  5.2Death, Disability or Voluntary
Retirement.  Upon
Executives death, medical disability which would preclude Executive from
performing the duties as the President and Chief Operating Officer of Holding
Co. and Chief Executive Officer of Bank for a period of six months, or
voluntary retirement, Executive shall not be entitled to any severance payment;
provided, however, that if such termination occurs as a result of such medical
disability, Executive   6 
   shall
receive a severance payment in an amount equal to twenty-five percent (25%) of
Executives annual base salary then in effect.  5.3           With Cause.  Either Holding Co. or Bank may terminate this Agreement at any
time by action of their Board of Directors, (i) if Executive fails to perform
or habitually neglects the duties which he is required to perform hereunder,
(ii) if Executive engages in activity which materially adversely affects the
Holding Co.s or Banks reputation in the community or which evidences the lack
of Executives fitness or ability to perform Executives duties as reasonably
determined by the Boards of Directors in good faith, or (iii) if Executive
commits any act which would cause termination of coverage under the Holding
Co.s or Banks Bankers Blanket Bond. 
In the event Holding Co. or Bank terminates this Agreement for cause as
provided herein, Executive shall not be eligible for any severance benefits
otherwise contemplated by this Agreement. 
Such termination shall not prejudice any remedy which Holding Co. or
Bank may have at law, in equity, or under this Agreement.  5.4           Action by Supervisory Authority.  If the Bank is closed by or taken over by
the California Department of Financial Institutions or other supervisory
authority, including the Federal Deposit Insurance Corporation, such bank
supervisory authority may immediately terminate this Agreement without further
liability or obligation by Holding Co. or Bank to Executive.  6.             Ownership of Confidential Proprietary Information.  All records of the accounts of customers,
and any other records and books relating in any manner whatsoever to the
customers of Holding Co. or Bank, and all other files, books and records and
other materials owned by Holding Co. or Bank or used by it in conjunction with
the conduct of its business, whether prepared by Executive or otherwise coming
into his possession, shall be the exclusive property of Holding Co. or Bank
regardless of who actually prepared the original material, book or record.  All such books and records and other
materials shall be immediately returned to the Holding Co. or Bank by   7 
   Executive
on any termination of his employment.  7.             Trade Secrets.  During the term of this Agreement, Executive
will have access to and become acquainted with what Executive, Holding Co. and
Bank acknowledge are trade secrets, including the names of customers and
clients of Holding Co. and Bank, those customers financial condition and
financial needs, financial information regarding Holding Co. or Bank, and other
information relating to the Holding Co.s or Banks products, services and
methods of doing business.  Executive
agrees not to disclose any of Holding Co.s or Banks trade secrets, directly
or indirectly, or use them in any way, either during the term of Executives
employment (except as required in the course of employment with Holding Co. or
Bank) or for a period of twelve (12) months after the termination of this
Agreement.  8.             Indemnification.  To the extent permitted by and consistent

(ii) the Articles of Incorporation and the Bylaws of Holding Co. and Bank,

settlements and other amounts actually incurred by Executive in connection with
any proceeding to which Executive is a party by reason of the fact that
Executive is or was an agent of Holding Co. or Bank (as defined in Section 317)
if the proceeding arose from acts or omissions in the course and scope of
Executives employment other than willful misconduct or acts not covered by any
indemnification agreement between Holding Co. or Bank and Executive.  Holding Co. or Bank shall advance on behalf
of Executive all costs, including attorneys fees, as necessary with respect to
any such proceeding.  In the event any
applicable law shall require the issuance of an undertaking by Executive, such
