SEVERENCE COMPENSATION AGREEMENT

This agreement is entered into the 1st day of April,  2004 by and between Citizens  Business Bank (the "Bank"),
and Edwin J. Pomplun, EVP of the Bank (the "Executive").

Whereas,  the Bank's Board of Directors has  determined  that it is  appropriate to reinforce and encourage the
continued  attention  and  dedication  of members of the Bank's  Senior  Management  Committee,  including  the
Executive,  to their assigned duties without distraction in potentially  disturbing  circumstances arising from
the  possibility  of a Change in Control (as  defined  herein) of CVB  Financial  Corporation  (the  "Company")
directly or indirectly the Bank, a wholly owned subsidiary of the Company; and

Whereas,  this Agreement sets forth the compensation  which the Bank agrees it will pay to the Executive upon a
Change in Control and termination of the Executive's employment,

Now,  therefore,  in consideration of theses premises and the mutual covenants and agreements  contained herein
and to induce  the  Executive  to remain  employed  by the Bank and to  continue  to exert his best  efforts on
behalf of the Bank, the parties agree as follows:

1.  Compensation Upon a Change in Control.

In the event that a Change in Control occurs during the employment of the Executive and
(i)      the  Executive's  employment  is terminated by the Company or the Bank or any successor to the Company
                      or the  Bank  other  than  for  Cause  (as  defined  herein)  within  one (1) year of the
                      completion of such Change in Control; or
(ii)     the  Executive  terminates or resigns  Executive's  employment  for a Good Reason (as defined  herein)
                      within one (1) year of the completion of such Change in Control;
the  Executive  shall receive an amount equal to two times the  Executive's  annual base  compensation  for the
last calendar year ended immediately  preceding the Change in Control,  plus two times the average annual bonus
received  for the last two  calendar  years ended  immediately  preceding  the Change in Control.  Such amounts
shall be paid in a lump sum,  less  applicable  employment  and payroll  taxes,  within five (5) days after the
effective date of the termination of Executive's employment.

2.  Definitions.

(a)      Change in  Control.  For  purposes  of this  Agreement,  a "Change in  Control"  shall  deemed to have
         occurred if:

(i)      any one person,  or more than one person  acting as a group,  acquires (or has acquired  during the 12
                  month  period  ending on the date of the most recent  acquisition)  ownership of stock of the
                  Company or the Bank  possessing  more than 50% of the total voting power of the  Company's or
                  the Bank's stock; provided,  however, it is expressly acknowledged by the Executive that this
                  provision shall not be applicable to any person who is, as of the date of this  Agreement,  a
                  Director of the Company or the Bank;

                  (ii)     a majority of the  members of the  Company's  or the Bank's  Board of  Directors  is
                  replaced  during any 12 month  period by  directors  whose  appointment  for  election is not
                  endorsed  by a majority  of the  members of the  Company's  or the Bank's  board prior to the
                  date of the appointment or election;

(iii)    a merger or consolidation  where the holders of the Bank's or the Company's  voting stock  immediately
                           prior to the  effective  date of such merger or  consolidation  own less than 50% of
                           the voting stock of the entity surviving such merger or consolidation;

(iv)     any one  person,  or more than one person  acting as a group,  acquired  (or has  acquired  during the
                           twelve  month  period  ending  on the date of the most  recent  acquisition  by such
                           person or persons)  assets from the Bank that have a total fair market value greater
                           than 50% of the total  fair  market  value of all of the Bank's  assets  immediately
                           before the acquisition or acquisitions;  provided, however, transfer of assets which
                           otherwise  would  satisfy  the  requirements  of this  subsection  (iv)  will not be
                           treated as a change in the  ownership  of such assets if the assets are  transferred
                           to:
                           (A)      an  entity,  50% or more of the  total  value or  voting  power of which is
                           owned, directly or indirectly by the Company or the Bank;
                           (B)      a person,  or more than one person acting as a group,  that owns,  directly
                           or  indirectly,  50% or  more  of  the  total  value  or  voting  power  of all  the
                           outstanding stock of the Company or the Bank; or
(C)      an entity,  at least 50% of the total  value or voting  power is owned,  directly or  indirectly  by a
                           person who owns,  directly or  indirectly,  50% or more of the total value or voting
                           power of all the outstanding stock of the Bank.

           Not  withstanding  the  foregoing,  a Change in Control  shall not be deemed to occur as a result of
           any transaction which changes the jurisdiction of incorporation of the Company or the Bank.

(b)      Cause.  For  purposes of this  Agreement,  the Bank shall have "Cause" to  terminate  the  Executive's
         employment  and shall not be obligated  to make any  payments  hereunder or otherwise in the event the
         Executive has:

                  (i)      committed a significant  act of  dishonesty,  deceit or breach of fiduciary  duty in
                  the performance of Executive's duties as an employee of the Bank;

(iii)    grossly  neglected  or  willfully  failed  in any way to  perform  substantially  the  duties  of such
                  employment; or

(iv)     acted or failed to act in any other way that  reflects  materially  and  adversely on the Bank. In the
                  event of a  termination  of  Executive's  employment  by the Bank for  Cause,  the Bank shall
                  deliver  to  Executive  at the time the  Executive  is  notified  of the  termination  of his
                  employment  a  written   statement   setting  forth  in  reasonable   detail  the  facts  and
                  circumstances  claimed by the Bank to provide a basis for the  termination of the Executive's
                  employment for Cause.

         (c)      Good Reason.  For purposes of this Agreement, "Good Reason" means:
                  (i)      the Executive's then current level of annual base salary is reduced;

(ii)     there  is any  reduction  in the  employee  benefit  coverage  provided  to the  Executive  (including
                  pension, profit sharing, deferred compensation,  life insurance and health insurance, but not
                  including  incentive  bonuses) from the coverage  levels in effect  immediately  prior to the
                  Change in Control, unless that Company or the Bank provide substantially  equivalent employee
                  benefits to the Executive;

(iii)    the Executive  suffers a material  diminution of Executive's  title,  authority,  position,  reporting
                  relationship, responsibilities or offices;

(iv)     there is a  relocation  of the  Executive's  principal  business  office by more than fifty (50) miles
                  from its existing location; or

                  (v)      the  Company or the Bank fail to obtain  assumption  of any  employment  relating to
                  Executive by any successor or assign of the Bank; provided,  however, that termination by the
                  Executive for Good Reason must be made in good faith.

3.  Term.

This agreement shall terminate,  except to the extent that any obligation of the Bank hereunder  remains unpaid
as of such time, upon the earliest of:

(i)      the  termination  of the  Executive's  employment  from the Bank for any reason if a Change in Control
         has not occurred prior to the date of such termination;

(ii)     three (3) years from the date hereof if a Change in Control has not occurred during such period;

(iii)    the  termination of Executives'  employment from the Bank for Cause within one (1) year after a Change
         in Control;

(iv)     one (1)  year  after a  Change  in  Control  if  Executive  is  still  employed  with  the Bank or its
         successor; or

(v)      after a Change in Control of the  Company or the Bank upon  satisfaction  of all of the  Company's  or
         the Bank's obligations hereunder.

4.  No Obligation to Mitigate Damages; No Effect on Other Contractual Rights.

(a)      The  Executive  shall not be required to mitigate  damages or the amount of any payment  provided  for
         under this  Agreement by seeking other  employment  or otherwise,  nor shall the amount of any payment
         provided  for under this  Agreement  be reduced by any  compensation  earned by the  Executive  as the
         result of employment by another  employer after the effective date of  Termination,  or otherwise,  by
         his engagement as a consultant or his conduct of any other business activities.

(b)      The  provisions  of this  Agreement,  and any payment  provided  for  hereunder,  shall not reduce any
         amounts  otherwise  payable,  or in any way diminish the Executive's  existing rights, or rights which
         would  accrue  solely as a result of the  passage of time,  under any  employment  agreement  or other
         plan,  arrangement or deferred  compensation  agreement,  except as otherwise  agreed to in writing by
         the Bank and the Executive.

5.  Successor to the Bank.

(a)      The Bank will require any  successor or assign  (whether  direct or indirect by purchase or otherwise)
                  to all or substantially  all of the business and/or assets of the Bank, by written  agreement
                  with the  Executive,  to assume and agree to perform this  Agreement in full. As used in this
                  Agreement,  "Bank" shall mean the Bank as herein  before  defined and any successor or assign
                  to its business  and/or  assets as  aforesaid  which  executes  and  delivers  the  agreement
                  provided  for in this  section  5 or  which  otherwise  becomes  bound by all the  terms  and
                  provisions of this  Agreement by operations of law.  Notwithstanding  the  assumption of this
                  Agreement by a successor  assign of the Bank, if a Change in Control (as defined in section 2
                  (a) above) has occurred,  the Executive shall have and be entitled from such successor to all
                  rights under section 1 of this Agreement.

(b)      If the Executive  should die while any amounts are still payable to him  hereunder,  all such amounts,
                  unless  otherwise  provided  herein,  shall  be paid in  accordance  with  the  terms of this
                  Agreement to the  Executive's  devisee,  legatee,  or other  designee or, if there be no such
                  designee, to the Executive's estate. This Agreement shall,  therefore,  insure to the benefit
                  of and be  enforceable  by the  Executive's  personal and legal  representatives,  executors,
                  administrators, successors, heirs, distributees, devisees and legatees.

6.  Confidentiality.

The  Executive  shall  retain  in  confidence  any and all  confidential  information  known  to the  Executive
concerning  the Company and the Bank and its business so long as such  information  is not  otherwise  publicly
disclosed.

7.  Legal Fees and Expenses.

The Bank  shall  pay all  legal  fees and  expenses  which the  Executive  may incur as a result of the  Bank's
contesting the validity,  enforceability or the Executive's  interpretation of, or determinations,  under, this
Agreement if the Executive prevails in any such contest or proceeding.

8.  Limitation on Payments.

This Agreement is made expressly  subject to the provision of law codified at 12 U.S.C.  1828 (k) and 12 C.F.R.
Part 359 which regulate and prohibit  certain forms of benefits to Executive.  Executive  acknowledges  that he
understands  these  sections of law and that the Bank's  obligations  to make payments  hereunder are expressly
relieved if such payments violate these sections of law or any successors thereto.

Notwithstanding  any  other  provisions  of this  Agreement,  if the total  amounts  payable  pursuant  to this
Agreement,  together with other payments to which Executive is entitled,  would constitute an "excess parachute
payment"  (as defined in Section  280G of the  Internal  Revenue  Code),  as amended,  such  payments  shall be
reduced,  in such order and manner as the Bank and/or  Resulting  Entity may elect,  (or in the absence of such
elections,  as shall be determined by  Executive),  to the largest amount which may be paid without any portion
of such amount being subject to the excise tax imposed by Section 4999 of the Internal Revenue Code.

9.  Notice.

return receipt requested, postage prepaid as follows:
