                        SEVERANCE COMPENSATION AGREEMENT

This agreement is entered into the 21st day of March, 2001 by and between
Citizens Business Bank, a California banking corporation (the "Bank"), and Jay
W. Coleman, (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 Corp. (the "Company") or 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 these 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/her best efforts on behalf of
the Bank, the parties agree as follows:

1. Compensation Upon a Change in Control.

       (a) In the event that a (i) Change in Control occurs during the
employment of the Executive and (ii) (a) 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 year of the completion
of such Change in Control or (b) the Executive terminates or resigns Executive's
employment for a Good Reason (as defined herein) within one year of the
completion of such Change in Control, the Executive shall receive an amount
equal to the Executive's annual base compensation for the last calendar year
ended immediately preceding the Change in Control. Such amount shall be paid in
a lump sum, less applicable employment and payroll taxes, within five 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;

<PAGE>   2

              (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 or 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,
acquires (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 prior to the
acquisition;

       (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 prior to the acquisition; 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
prior to the acquisition.

Not withstanding the foregoing, a Change in Control shall not be deemed to occur
as a result of any transaction whose primary purpose is to change the
jurisdiction of incorporation of the Company or the Bank.

              (b) Cause. For purposes of this Agreement, the Bank, or any
successor thereto, 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; (ii) grossly neglected or willfully failed in any way to
perform substantially the duties of such employment; or (iii) 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/her 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

<PAGE>   3

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, or any
successor thereto, provide substantially equivalent employee benefits to the
Executive; (iii) the Executive suffers a material diminution in 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 by the Executive 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)
the termination of Executive's employment from the Bank for Cause within 1 year
after a Change in Control, (iii) 1 year after a Change in Control if Executive
is still employed with the Bank or its successor or (iv) 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/her engagement as a consultant or his/her 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 if this Agreement by operations of law. Notwithstanding the

<PAGE>   4

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/her 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

This agreement is made expressly subject to the provisions of law codified at 12
U.S.C. 1828 (k) and 12 C.F.R. Part 359 which regulate and prohibit certain forms

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
