     THIS  CHANGE IN CONTROL  AGREEMENT is entered  into as of Jan. 28, 1999, by
and between BRUCE MACLIN (the "Employee") and SAN JOAQUIN BANK, (the "Bank").

     1.   CHANGE IN CONTROL.
          ------------------

          (a)  DEFINITION.  For all purposes under this  Agreement,  "Change  in
Control" shall mean the occurrence of any of the following events after the date
of this Agreement:

               (i)   the dissolution or liquidation of the Bank;

               (ii)  a reorganization,  merger or consolidation of the Bank with
          one or more  corporations  as a result  of  which  the Bank is not the
          surviving corporation;

               (iii) any sale,  lease,  exchange or other  transfer (in one or a
          series of transactions)  of all or substantially  all of the assets of
          the Bank;

               (iv)  any  merger  or  consolidation  of the  Bank in  which  the
          holders of voting stock of the Bank  immediately  before the merger or
          consolidation  will  not  own  fifty  percent  (50%)  or  more of  the
          outstanding  voting shares of the continuing or surviving  corporation
          immediately after such merger or consolidation; or

               (v)   a change of 50% or more (rounded to the next whole  person)
          in the  membership  of the  Board of  Directors  of the Bank  within a
          12-month period,  unless the election or nomination by stockholders of
          each new  director  within such period was  approved by the vote of at
          least 75%  (rounded to the next whole  person) of the  directors  then
          still in office who were in office at the  beginning  of the  12-month
          period.

          (b)  GOOD REASON. For all purposes under this Agreement, "Good Reason"
shall mean that the Employee:

               (i)   Has  incurred a  material  reduction  in his  authority  or
          responsibility as the Bank's Chairman of the Board;

               (ii)  Has incurred a reduction in his "base  compensation," bonus
          opportunity or benefits and perquisites; or

               (iii) Has been notified that his princip al place of work will be
          relocated by a distance of 50 miles or more.

                                       1


     For purposes of this Agreement,  "base  compensation" shall mean annualized
base salary as  reflected in the Bank's  payroll  records as of the date of this
Agreement and as may be subsequently adjusted upward for increases.

          (c)  SEVERANCE  PAYMENT.  The Employee  shall be entitled to receive a
severance  payment from the Bank (the  "Severance  Payment") if within the first
twenty-four  (24) month period after the  occurrence of a Change in Control [the
twenty-four (24) month  period  will be renewed if a separate  Change of Control
occurs within twenty-four (24) months of the preceding Change of Control]:

               (i)   The Employee  voluntarily  resigns his  employment for Good
          Reason;

               (ii)  The  Bank  terminates  the  Employee's  employment for  any
          reason other than Cause or Disability; or

               (iii) If, during the 30-day  period  commencing on the date which
          is 90 days after the Change in Control  the  Employee  terminates  his
          employment (with or without Good Reason).

The  Severance  Payment  shall  be made in a lump  sum not  more  than  five (5)
business days following the date of the employment  termination and shall  be in
an amount  determined under Subsection (d) below. The Severance Payment shall be
in  lieu of any  other  payments,  including payments under the Bank's severance
policy, or benefits for periods subsequent to the termination of employment.

     For all purposes under this Agreement, "Cause" shall mean :

               (i)   A willful act by the Employee which constitutes  misconduct
          or fraud and which has a material adverse effect on the Bank; or

               (ii)  Conviction  of, or a plea of "guilty" or "no contest" to, a
          felony.

No act, or failure to act, by the Employee shall be considered "willful"  unless
committed  without  good faith and without a  reasonable  belief that the act or
omission was in the Bank's best interest.

     "Disability"  shall have the same  meaning  as under the  Bank's  Long-Term
Disability Plan.

          (d)  AMOUNT. The amount of the Severance Payment shall be equal to the
sum of the following:

               (i)   3 times the Employee's annual rate of base compensation, as
          in effect on the date of the  employment  termination  (or if greater,
          the date of this Agreement); plus

               (ii)  3 times the highest annual bonus awarded to the Employee by
          the  Bank  during  the  last  three  years  prior  to the  date of the
          employment termination (regardless of when paid).

                                       2


[HANDWRITTEN NOTATION STRIKING OUT PARAGRAPH BELOW:  DELETED BY AMENDMENT #1]

     Notwithstanding  the  foregoing,   the  amount  payable  pursuant  to  this
Agreement  shall  be the  lesser  of (i) one  percent (1%) of the  Consideration
involved  in the  transaction  giving  rise to the  Change in  Control as of the
closing   of  any   applicable   transaction   or  other   event  AND  (ii)  the
amount determined utilizing the formula set forth above; provided, however, that
under no  circumstances  shall the  amount  payable  be reduced to less than the
amount determined utilizing the above formula where "2 times" is substituted for
"3 times" in Section 1(d)(i) and 1(d)(ii).  For purposes of this Agreement,  the
term "Consideration"  shall mean the total proceeds and other consideration paid
or received or to be paid or received in connection with the transaction  (which
consideration  shall be deemed to include amounts in escrow),  including without
limitation:  (A) cash; (B) notes,  securities and other  property;  (C) payments
made in installments;  (D) amounts payable under employment contracts (in excess
of ordinary compensation),  consulting agreements,  agreements not to compete or
similar arramgements  (including such payments to management) other than amounts
payable pursuant to this Agreement;  (E) earnout or contingent payments (whether
or not related to future earnings or operations); (F) any indebtedness for money
borrowed or other liability that is assumed in connection with the  transaction;
and (G) the net value of assets not sold in connection  with any  disposition of
assets.

[HANDWRITTEN NOTATION STRIKING OUT PARAGRAPH BELOW:  DELETED BY AMENDMENT #1]

     Earnout  or  contingent  payments  will be  valued  at the  closing  of the
transaction  based on the best case  financial  plan put forth by the Bank.  For
purposes of this definition,  non-cash consideration shall be valued as follows:
(A)  publicly  traded  securities  shall be valued as the average of the closing
prices (as recorded in the Wall Street  Journal) for the five trading days prior
to the closing of the transaction and (B) any other non-cash consideration shall
be valued at the fair market value  thereof as  determiend  in good faith by the
Bank. In the event of a transaction,  other than acquisition of assets, in which
less than all of the stock of the Bank is acquired,  the Consideration  shall be
calculated  pursuant  to this  paragraph  as a sale of stock in which all of the
stock of the Bank has been  acquired at a price  equal to the highest  price per
share paid for any shares  acquired  during the five  trading  days prior to the
closing of the transaction.

[HANDWRITTEN NOTATION STRIKING OUT PARAGRAPH BELOW:  DELETED BY AMENDMENT #1]

     In the event of a Change in Control  described in Section  1(a)(v) which is
not also described in Section 1(a)(i) through (iv),  "Consideration"  shall mean
the valuation of the Bank calculated by the actual number of outstanding  shares
of stock in the Bank  multiplied  by the  average  of the  closing  price of the
Bank's  stock for the  thirty  (30) trading days prior to the  date on which the
Change in Control occurs (whether or not any trades actually occurred).

          (e)  INCENTIVE PROGRAMS. If a Change in Control occurs with respect to
the Bank,  the Employee  shall become fully vested in all awards  heretofore  or
hereafter  granted to him under all stock  option,  stock  appreciation  rights,
restricted  stock,  phantom  stock or similar  plans or  agreements of the Bank,
regardless of any provisions in such plans or agreements that do not provide for
full  vesting.  (To the extent  that such plans or  agreements  provide for full
vesting on an earlier date than this Agreement,  such plans or agreements  shall
prevail.)

     On or immediately prior to a Change of Control,  the  Bank will  contribute
to an irrevocable  grantor trust the then present value of the Employee's  fully
vested benefit under the Employee Salary Continuation Agreement dated October 3,
1996, as amended April 10, 1997,  April 15, 1998, and January 28, 1999,  between
the  Employee  and the  Bank  (the  "ESC").  Upon a  termination  of  employment

                                       3


described in  Subsection  (c) above,  the Employee  will receive a lump sum cash
distribution  from the trust equal to the amount  determined in accordance  with
the ESC.

          (f)  INSURANCE  COVERAGE.  During the  thirty-six  (36)  month  period
commencing  upon a termination of employment  described in Subsection (c) above,
the  Employee  (and,  where  applicable,  his  dependents)  shall be entitled to
continue  participation  in the group  insurance  plans  maintained by the Bank,
including life, disability and health insurance programs, as if he were still an
employee of the Bank. Where  applicable,  the Employee's  salary for purposes of
such  plans  shall  be  deemed  to be equal  to his  base  compensation  used in
Subsection  (d)(i)  above.  To  the extent that the Bank finds it  impossible to
cover the Employee under its group  insurance  policies  during such  thirty-six
(36) month period, the Bank shall provide the Employee with individual  policies
which offer at least the same level of coverage  and which  impose not more than
the  same  costs  on him as if he  were  still  an  employee  of the  Bank.  The
foregoing  notwithstanding,  in the event that the Employee becomes eligible for
comparable  group  insurance  coverage in connection  with new  employment,  the
coverage  provided  by the  Bank  under  this  Subsection  (f)  shall  terminate
immediately.  Any group health continuation  coverage that the Bank is otherwise
required to offer under the Consolidated  Omnibus Budget  Reconciliation  Act of
1986  ("COBRA")  shall be  offered  when  coverage  under  this  Subsection  (f)
terminates.

          (g)  NO MITIGATION. The Employee shall not be required to mitigate the
amount of any  payment  contemplated  by this  Section 1 (whether by seeking new
employment or in any other manner).  Except as expressly  provided in Subsection
(f) above,  no such payment  shall be reduced by earnings  that the Employee may
receive from any other source.

     2.   TAX EFFECT OF PAYMENTS.
          -----------------------

          (a)  GROSS-UP  PAYMENT.  In the event that it is  determined  that any
payment or  distribution  of any type to or for the benefit of the Employee made
by the Bank, by any of its affiliates,  by any person who acquires  ownership or
effective  control  of the Bank or  ownership  of a  substantial  portion of the
Bank's assets  [within the meaning of Section 280G of the Internal  Revenue Code
of 1986,  as amended,  and the  regulations  thereunder  (the "Code")] or by any
affiliate  of  such  person,   whether  paid  or  payable  or   distributed   or
distributable  pursuant to the terms of this  Agreement or otherwise (the "Total
Payments"),  would be subject to the excise tax  imposed by Section  4999 of the
Code or any interest or  penalties  with respect to such excise tax (such excise
tax, together with any such interest or penalties,  are collectively referred to
as the  "Excise  Tax"),  then the  Employee  shall be  entitled  to  receive  an
additional  payment  (a  "Gross-Up  Payment")  in an amount  that shall fund the
payment by the  Employee of any Excise Tax on the Total  Payments as well as all
income  taxes  imposed on the  Gross-Up  Payment,  any Excise Tax imposed on the
Gross-Up Payment and any interest or penalties  imposed with respect to taxes on
the Gross-Up Payment or any Excise Tax.

          (b)  DETERMINATION BY AUDITORS.  All mathematical  determinations  and
all determinations of whether any of the Total Payments are "parachute payments"
(within  the meaning of Section  28OG of the Code) that are  required to be made
under this Section 2, including all determinations of whether a Gross-Up Payment
is required,  of the amount of such Gross-Up  Payment and of amounts relevant to
the last sentence of this Section 2, shall be made by the  independent  auditors

                                       4


retained  by the  Bank,  most  recently  prior to the  Change  of  Control  (the
"Auditors"),  who  shall  provide  their  determination  (the  "Determination"),
together  with  detailed  supporting  calculations  regarding the  amount of any
Gross-Up  Payment and any other  relevant  matters,  both to the Bank and to the
Employee within seven (7) business days of the Employee's  termination  date, if
applicable,  or such earlier time as is requested by the Bank or by the Employee
(if the  Employee  reasonably  believes  that any of the Total  Payments  may be
subject to the Excise  Tax).  If the  Auditors  determine  that no Excise Tax is
payable by the Employee,  it shall furnish the Employee with a written statement
that such Auditors have concluded  that no Excise Tax is payable  (including the
reasons therefor) and that the Employee has substantial  authority not to report
any  Excise  Tax on the  Employee's  federal  income tax return.  If a Gross- Up
Payment is  determined  to be payable,  it shall be paid to the Employee  within
five (5) business days after the  Determination  is delivered to the Bank or the
Employee.  Any  determination by the Auditors shall be binding upon the Bank and
the Employee,  absent manifest error.

          (c)  UNDERPAYMENTS AND OVERPAYMENTS. As a result of uncertainty in the
application of Section 4999 of the Code at the time of the initial determination
by the Auditors hereunder, it is possible that Gross-Up Payments not made by the
Bank should have been made ("Underpayments") or that Gross-Up Payments will have
been  made by the Bank  which  should  not have been made  ("Overpayments").  In
either event,  the Auditors shall  determine the amount of the  Underpayment  or
Overpayment  that has occurred.  In the case of an  Underpayment,  the amount of
such  Underpayment  shall promptly be paid by the Bank to or for the benefit  of
the  Employee.  In the  case  of an  Overpayment,  the  Employee  shall,  at the
direction and expense of the Bank, take such steps as  are reasonably  necessary
(including  the filing of returns  and claims  for  refund),  follow  reasonable
instructions  from,  and  procedures  established  by,  the Bank  and  otherwise
reasonably  cooperate  with  the Bank to correct  such  Overpayment;   provided,
however,  that (i) the Employee shall in  no event be obligated to return to the
Bank an amount greater than the net after-tax  portion of the  Overpayment  that
the  Employee  has  retained or has  recovered  as a refund from the  applicable
taxing,  authorities  and (ii) this  provision  shall be interpreted in a manner
consistent  with the intent of this  Section  2,  which is to make the  Employee
whole,  on an after-tax  basis,  for the application of the Excise Tax, it being
understood  that the correction of an  Overpayment  may result in the Employee's
repaying  to the  Bank  an  amount  which  is less  than  the  Overpayment.

     3.   SUCCESSORS.
          -----------

          (a)  BANK'S SUCCESSORS.  The Bank shall require any successor (whether
direct or  indirect  and  whether by  purchase,  lease,  merger,  consolidation,
liquidation  or otherwise) to all or  substantially  all of the Bank's  business
and/or  assets,  by an  agreement  in  substance  and form  satisfactory  to the
Employee,  to assume  this  Agreement  and to agree  expressly  to perform  this
Agreement  in the same  manner  and to the  same  extent  as the  Bank  would be
required to perform it in the  absence of a  succession.  The Bank's  failure to
obtain  such  agreement  prior to the  effectiveness  of a  succession  shall be
treated as grounds for the Employee to terminate employment for Good Reason. For
all purposes under this  Agreement,  the term "Bank" shall include any successor
to the Bank's  business and/or assets which executes and delivers the assumption
agreement  described  in this  Subsection  (a) or  which  becomes  bound by this
Agreement by operation of law.

                                       5


          (b)  EMPLOYEE'S  SUCCESSORS.  This  Agreement  and all  rights  of the
Employee  hereunder  shall inure to the benefit of, and be  enforceable  by, the
Employee's  personal  or  legal  representatives,   executors,   administrators,
successors, heirs, distributees, devisees and legatees.

     4.   MISCELLANEOUS PROVISIONS.
          -------------------------

          (a)  NOTICE. Notices and all other communications contemplated by this
Agreement  shall be in writing  and shall be deemed to have been duly given when
personally  delivered   or when mailed by U.S.  registered  or  certified  mail,
return  receipt  requested  and postage  prepaid . In the case of the  Employee,
mailed  notices  shall be  addressed  to him at the home  address  which he most
recently  communicated to the Bank in writing.  In the case of the Bank,  mailed
notices shall be addressed to its corporate headquarters,  and all notices shall
be directed to the attention of its Secretary.

          (b)  WAIVER. No provision of this Agreement shall be modified,  waived
or  discharged  unless  the  modification,  waiver or  discharge is agreed to in
writing  and  signed by the Employee  and by an  authorized  officer of the Bank
(other than the  Employee).  No waiver by  either  party of any breach of, or of
compliance with, any condition or provision of this Agreement by the other party
shall be considered a waiver of any other  condition or provision or of the same
condition or provision at another time.

          (c)  WHOLE AGREEMENT. No agreements, representations or understandings
(whether oral or written and whether express or implied) which are not expressly
set forth in this  Agreement have been made or entered into by either party with
respect to the subject matter hereof.

          (d)  NO SETOFF;  WITHHOLDING  TAXES. There shall be no right of setoff
or counterclaim, with respect to any claim, debt or obligation, against payments
to the Employee  under this  Agreement.  All payments made under this  Agreement
shall be subject to reduction to reflect taxes required to be withheld by law.

          (e)  CHOICE OF LAW. The  validity,  interpretation,  construction  and
performance  of this  Agreement  shall be  governed  by the laws of the State of
California.

          (f)  SEVERABILITY. The invalidity or unenforceability of any provision
or provisions of this Agreement shall not affect the validity or  enforceability
of any other provision hereof, which shall remain in full force and effect.

          (g)  ARBITRATION OF DISPUTES.  All claims,  disputes and other matters
in  question  arising  out of or  relating  to this  Agreement  or the breach or
interpretation  thereof,  other than those matters which are to be determined by
the Bank in its sole and  absolute  discretion,  shall be  resolved  by  binding
arbitration before a representative member,  selected by the mutual agreement of
the parties, of the Judicial Arbitration and Mediation Services, Inc . ("JAMS"),
presently located at 111 Pine Street, Suite 710 in San Francisco, California. In
the event JAMS is unable or  unwilling to conduct the  arbitration  provided for
under the terms of this paragraph, or has discontinued its business, the parties

                                       6



agree that a  representative  member,  selected by the mutual  agreement  of the
parties, of the American Arbitration  Association ("AAA"),  presently located at
417 Montgomery Street, in San Francisco,  California,  shall conduct the binding
arbitration referred to in this paragraph. Notice of the demand for arbitration
shall be filed in writing with the other party to this  Agreement  and with JAMS
(or AAA, if  necessary).  In no event shall the demand for  arbitration  be made
after the date when institution of legal or equitable  proceedings based on such
claim,  dispute or other  matter in question  would be barred by the  applicable
statute  of  limitations.  The  arbitration  shall be  subject  to such rules of
procedure  used or  established  by JAMS,  or if there  are  none,  the rules of
procedure  used or  established by AAA.  Any award rendered by JAMS or AAA shall
be final and binding upon the parties, and  as applicable, upon their respective
heirs, beneficiaries, legal representatives, agents, successors and assigns, and
may be entered in any courts having jurisdiction  thereof. The obligation of the
parties to arbitrate  pursuant to this clause shall be specifically  enforceable
in accordance with, and shall be conducted  consistently with, the provisions of
Title 9 of Part 3 of the California  Code of Civil  Procedure.  Any  arbitration
hereunder shall be conducted in Bakersfield, California, unless otherwise agreed
to by the parties.

          (h)  ATTORNEYS'  FEES. In the event of any  arbitration  or litigation
concerning any controversy, claim or dispute between the parties hereto, arising
out of or relating to this Agreement or the breach hereof, or the interpretation
hereof,  the prevailing party shall be entitled to recover from the losing party
reasonable expenses,  attorneys' fees and costs incurred in connection therewith
or in the  enforcement or collection of any judgment or award rendered  therein.
The "prevailing party" means the party determined by the arbitrator(s) or court,
as the case may be, to have most  nearly  prevailed,  even if such party did not
prevail in all  matters,  not  necessarily  the one in whose favor a judgment is
rendered.

          (i)  NO  ASSIGNMENT.  The rights of any person to payments or benefits
under this Agreement  shall not be made subject to option or assignment,  either
by  voluntary  or  involuntary  assignment  or by  operation  of law,  including
(without  limitation)  bankruptcy,  garnishment,  attachment or other creditor's
process, and any action in violation of this Subsection (i) shall be void.

     IN WITNESS WHEREOF, each of the parties has executed this Agreement, in the
case of the Bank by its duly  authorized  officer,  as of the day and year first
above written
