QUESTIONS AND ANSWERS FOR SHAREHOLDERS OF VALLEY BANK
ABOUT THE
SHAREHOLDER DOCUMENTS

Q: I AM A SHAREHOLDER OF VALLEY BANK. WHY MUST I COMPLETE THESE DOCUMENTS?

A: Pacific Community Banking Group has agreed to acquire Valley Bank. You have
received a proxy statement/prospectus that describes Pacific Community
Banking Group and the acquisition. If the shareholders approve the
acquisition, Valley Bank needs the shareholder documents to complete the
acquisition and to arrange for you to receive the cash, stock and warrants
you will be entitled to receive.

Q: WHAT IS THE CUSTODY AGREEMENT, LETTER OF TRANSMITTAL, POWER OF ATTORNEY AND
OFFER OF SALE?

A: You should read the entire document. But in summary, the Custody Agreement,
Letter of Transmittal, Power of Attorney and Offer of Sale is a binding
agreement by you that principally provides the following:

- You appoint a custodian, which will hold your shares and deliver them as
necessary to complete the acquisition and the public offering.

- You provide your name, address and other necessary information to ensure
that you receive the cash, stock and warrants to which you are entitled,
and you state a preference to receive a greater amount of cash or of stock
after the close of the acquisition and the public offering. You also
promise that you own your shares and have the power to sell them.

- You give a special power of attorney to two individuals, referred to as
the 'Attorneys-in-Fact,' who will take limited legal actions on your
behalf to establish the final price of your Pacific Community Banking
Group stock and sell some or all of that stock to the underwriters.

- You offer the shares of Pacific Community Banking Group common stock you
will receive in the acquisition to the underwriters. The underwriters will
be able to purchase some or all of the shares for resale at a price to the
public of at least $15 per share.

Q: WHO IS THE CUSTODIAN AND WHAT WILL THE CUSTODIAN DO?

A: U.S. Stock Transfer Corporation will be the custodian. You should send your
certificates to the custodian now, along with the selling shareholder
documents. If the acquisition closes, the custodian will surrender the
certificates for your shares of Valley Bank common stock. In exchange for
each share so surrendered you will receive two thirds of a share of Pacific
Community Banking Group common stock and one third of a warrant. The
custodian will keep custody of your shares of Pacific Community Banking
Group for the brief period until the public offering closes, then deliver
the shares you sell to the underwriter, send you the money received from the
sale and send you certificates for the shares you don't sell, and for your
warrants.

Q: WHO ARE THE "ATTORNEYS-IN-FACT" AND WHAT POWER WILL THEY HAVE?

A: An individual that has the power to act on your behalf under the Power of
Attorney is called an "Attorney-in-Fact." You will authorize any of two
persons, Marion V. Ashley and N. Douglas Mills, to act in this capacity.
They will negotiate the final price to the public of the shares of Pacific
Community Banking Group common stock you sell, with a minimum price of $15.
They will sell your shares of

Pacific Community Banking Group common stock to the underwriters on those
terms. The Attorneys-in-Fact will consider the preference for cash or stock
that you have stated. But they will have the discretion to designate some or
all of your stock to be sold to the public, in order to meet the terms of
the acquisition agreement. They can also sign any documents necessary to
complete the sale, on your behalf, including an underwriting agreement,
without further consultation with you.

Q: CAN I ELECT TO RECEIVE CASH ONLY OR PACIFIC COMMUNITY BANKING GROUP COMMON
STOCK ONLY?

A: No. You will be able to indicate your preference to have (a) 100% cash or
(b) 100% stock of Pacific Community Banking Group or (c) 60% cash and 40%
stock of Pacific Community Banking Group after the close of the acquisitions
and the initial public offering. The Attorneys-in-Fact will consider this
when determining how much of your Pacific Community Banking Group common
stock to sell to the underwriters. But even if you indicate a preference for
100% stock, it is likely that some of your shares will be sold because the
acquisition agreement requires that the underwriters purchase and resell 60%
of the total shares received by shareholders of Valley Bank. Similarly, even
if you indicate a preference to receive all cash, you may be required to
keep some amount of Pacific Community Banking Group Stock.

Q: WHAT OTHER KINDS OF INFORMATION WILL I NEED TO PROVIDE?

A: In addition to your name and address, you will give instructions for where
the transfer agent should send the money received from the sale and any
remaining shares and your warrants. If you have more than one certificate,
or have a number of separate purchases on your brokerage account, you can
indicate which of them you prefer to sell first, which can affect the amount
of taxable capital gain you realize if you paid different amounts per share
in your original purchases. You will also need to return a completed form
W-9 for tax reporting purposes. Please consult your tax advisor if you have
questions about the tax effects of designating particular shares for sale.

Q: WHAT IF I DON'T HAVE PHYSICAL CERTIFICATES FOR MY SHARES, BUT HOLD THEM
THROUGH AN ACCOUNT AT MY BROKER?

A: If you don't have certificates, but hold your shares of Valley Bank common
stock "in street name," that is, through a brokerage account, you should
still complete all of the enclosed shareholder documents. Your broker will
tell you where and how to return the completed documents. Then the surrender
and exchange of certificates, and the sale of stock, will take place on your
behalf. You will receive the cash proceeds from the sale of your Pacific
Community Banking Group common stock. Any remaining shares of Pacific
Community Banking Group common stock and the warrants will be recorded on
your brokerage account.

Q: WHAT IF THE ACQUISITION OR THE PUBLIC OFFERING IS NOT COMPLETED?

A: If either the acquisition or the public offering fails to take place, the
custodian will return to you the certificates for the shares of Valley Bank
common stock you surrendered, or send you replacement certificates.

Q: WHAT IF I LOST THE CERTIFICATES FOR MY SHARES?

A: If you have lost the certificates for your shares, please complete and
return the enclosed Lost Certificate Declaration, along with the other
applicable shareholder documents.

Q: IS IT SAFE TO SEND MY CERTIFICATES BY MAIL OR BY OVERNIGHT EXPRESS?

A: Please do NOT send signed stock certificates by mail or by overnight
express. Unless you will hand deliver your certificates, sign one of the
enclosed Stock Powers for each of your certificates rather than signing the
certificates. Then send the certificates and the stock powers by certified
mail IN SEPARATE ENVELOPES.

Q: WILL I BE RESPONSIBLE FOR ANY OF THE COSTS OF THE PUBLIC OFFERING?

A: No. Pacific Community Banking Group will pay the underwriters' commissions
and other costs of reselling your shares in the public offering. You will
receive the gross amount obtained for the shares you sell immediately.

Ladies and Gentlemen:

The undersigned (the "Shareholder") is a shareholder of Valley Bank ("Valley
Bank"), a California corporation. Pacific Community Banking Group, a California
corporation, and Valley Bank have signed a First Restatement of Agreement and
Plan of Reorganization (as amended, the "Acquisition Agreement") providing for
the acquisition of Valley Bank by Pacific Community Banking Group. If the
acquisition is completed, the Shareholder's shares of Valley Bank will
automatically convert into a right to receive shares of Pacific Community
Banking Group. Pacific Community Banking Group and the Shareholder propose to
sell some or all of the shares of Pacific Community Banking Group common stock
received by the Shareholder to underwriters (the "Underwriters") for whom Sutro
& Co. Incorporated will act as representative (the "Representative" ), for
distribution under a Registration Statement on Form S-1 (the "Registration
Statement") to the public at a price and on terms to be hereafter determined. It
is understood that at this time there is no commitment on the part of the
Underwriters to purchase any shares of Pacific Community Banking Group common
stock and no assurance that an offering of Pacific

Community Banking Group common stock will take place. The shares of Pacific
Community Banking Group common stock received by the Shareholder in exchange for
shares of Valley Bank common stock, all of which the Shareholder will hereby
offer to sell to the Underwriters, are referred to herein as the "Shares."

1. APPOINTMENT AND POWERS OF ATTORNEYS-IN-FACT.

A. The Shareholder irrevocably constitutes and appoints Marion V. Ashley
and N. Douglas Mills (the "Attorneys-in-Fact"), and each of them, its agent and
attorney-in-fact, with full power of substitution, with respect to all matters

including, but not limited to, the power and authority on behalf of the
Shareholder to do or cause to be done any of the following things:

for all of the Shareholders' shares of common stock of Valley Bank in
exchange for shares of Pacific Community Banking Group as provided in
the Acquisition Agreement;

(ii) to negotiate, determine and agree upon (a) the price at which the
Shares will be initially offered to the public by the Underwriters,
provided that the price shall not be less than $15 per share, and (b)
the price at which the Shares will be sold to the Underwriters;

(iii) to execute on behalf of the Shareholder an underwriting agreement as
follows: (a) making the representations and warranties of the
Shareholder contained in this Agreement to the Underwriters; (b)
undertaking the obligations of the Shareholder contained in this
agreement, for the benefit of the Underwriters; and (c) indemnifying
the Underwriters, on a joint and several basis with Pacific Community
Banking Group and the other Shareholders, for losses resulting from a
breach of those representations, warranties and obligations, up to the
amount of consideration received by the Shareholder for shares of
Pacific Community Banking Group sold to the public in the initial
public offering. Such indemnification may include a provision for
interim reimbursement and contribution, with the underwriters having a
similar obligation to the shareholders participating in the public
offering.

(iv) to allocate the number of shares of Pacific Community Banking Group
common stock owned by the Shareholder that shall be sold to the
Underwriters and the number of shares of Pacific Community Banking
Group common stock that shall be retained by the Shareholder, in
satisfaction of the terms of the Acquisition Agreement. NOTWITHSTANDING
THE STATEMENT OF PREFERENCE MADE BY THE SHAREHOLDER HEREIN, THE
ATTORNEYS-IN-FACT ARE AUTHORIZED, IN THEIR SOLE DISCRETION, TO SELL UP

BY THE SHAREHOLDER.

securities or "blue sky" laws of various states and jurisdictions,
including, without limitation, the giving or making of such
undertakings, representations and agreements and the taking of such
other steps as the Attorneys-in-Fact may deem necessary or advisable;

hereinafter defined) on all matters pertaining to the sale of the
Shares and delivery of certificates therefor; and

required, contemplated or deemed advisable or desirable by the
Attorneys-in-Fact in their discretion, including the

execution and delivery of any documents, and generally act for and in
the name of the Shareholder with respect to the sale of the Shares to
the Underwriters and the reoffering of the Shares by the Underwriters
as fully as could the Shareholder if then personally present and
acting.

B. Each Attorney-in-Fact may act alone in exercising the rights and powers
conferred on the Attorneys-in-Fact by this Custody Agreement, Letter of
Transmittal, Power of Attorney and Offer of Sale (this "Agreement"), and the act

which, any power herein conferred upon the Attorneys-in-Fact shall be exercised.

all other persons dealing with the Attorneys-in-Fact as such may rely and act

association, or credit union, with membership in an approved medallion signature
program, or (b) the Shareholder has separately provided a duly executed stock

shall retain all rights of ownership with respect to the shares of Valley Bank
common stock deposited hereunder, including the right to vote and to receive all

of or dispose of such Shares, which right is subject to this Agreement.

the Shares. The Attorneys-in-Fact are authorized, on behalf of the Shareholder,
to accept and acknowledge receipt of the payment of the purchase price for the
Shares and shall promptly deposit such proceeds with the Custodian. The

by the Shareholder and (assuming this Agreement is a binding Agreement of the
other parties thereto) constitutes the valid and binding agreement of the
Shareholder, enforceable against the Shareholder in accordance with its terms
(except as such enforceability may be limited by applicable bankruptcy,

relating to or affecting the enforcement of creditors' rights and the
application of equitable principles relating to the availability of remedies,
and except as rights to indemnity or contribution may be limited by federal or
state securities law and the public policy underlying such laws).

B. None of the execution, delivery or performance of this Agreement and the
consummation of the transactions herein contemplated will conflict with or
result in a breach of, or default under, any indenture, mortgage, deed of trust,
voting trust agreement, shareholders' agreement, note agreement or other
agreement or instrument to which the Shareholder is a party or by which the
Shareholder is bound or to which any of his or its property is or may be
subject, or any statute, judgment, decree, order, rule or regulation applicable
to the Shareholder of any government, arbitrator, court, regulatory body or

administrative agency or other governmental agency or body, domestic or foreign,
having jurisdiction over the Shareholder or any of his activities or properties.

C. At the date hereof, the Shareholder has full right, power and authority

be surrendered in exchange for the Shares, and at the time of delivery of the
Shares to be sold by the Shareholder to the several Underwriters, the
Shareholder will have full right, power and authority to sell, assign, transfer
and deliver the Shares to be sold by the Shareholder hereunder. At the date
hereof the Shareholder is the lawful owner of and has good and marketable title
to the shares of Valley Bank common stock to be surrendered in exchange for the
Shares, free and clear of any and all encumbrances, and at the time of delivery
of the Shares to be sold by the Shareholder, the Shareholder will be the lawful

any and all encumbrances.

D. To the Shareholder's knowledge, the Shareholder has not taken any action
designed to stabilize or manipulate the price of any security of Pacific

reasonably be expected to cause or result in stabilization or manipulation of
the price of any security of Pacific Community Banking Group, to facilitate the
sale or resale of the Shares or otherwise.

E. If the Shareholder is acting as a fiduciary, officer, partner or agent,
the Shareholder is enclosing with this Agreement certified copies of the
appropriate instruments pursuant to which the Shareholder is authorized to act
hereunder. If the Shareholder is an individual and is married, and the spouse is

in the form attached to this Agreement as Annex A.

Group or the Underwriters or any of their respective counsel may reasonably
request in order to effectuate any of the provisions hereof, in form and
substance satisfactory in all respects to the Attorneys-in-Fact.

the benefit of, and may be relied upon by, the Attorneys-in-Fact, Valley Bank,
Pacific Community Banking Group, the Custodian, the Underwriters and their
respective representatives, agents and counsel.

Acquisition Agreement and the Underwriting Agreement between Pacific Community
Banking Group, certain other selling shareholders and the Underwriters, and (b)

authority sufficient to consummate said transactions. Accordingly, this
Agreement and the offer of the Shares made herein shall be irrevocable prior to
August 4, 1999, and shall remain in full force and effect until that date, which

further agrees that this Agreement shall not be terminated by operation of law
or upon the occurrence of any event whatsoever, including the death, disability
or incompetence of the Shareholder or, if the Shareholder is not a natural
person, upon any dissolution, winding up, distribution of assets or other event
affecting the legal existence of the Shareholder. If any event referred to in
the preceding sentence shall occur, whether with or without notice thereof to
the Attorneys-in-Fact, any of the Underwriters or any other person, the
Attorneys-in-Fact shall nevertheless be authorized and empowered to deliver and
deal with the Shares deposited under the Agreement by the Shareholder in
accordance with the terms and provisions of this Agreement as if such event had
not occurred.

B. If the transactions contemplated in the Acquisition Agreement are not

agents, successors, assigns and personal representatives with respect to any act
or omission of or by any of them in good faith in connection with any and all
matters contemplated by this Agreement or the Underwriting Agreement.

termination of this Agreement.

upon, the Shareholder and the Shareholder's heirs, executors, administrators,
successors and assigns, as the case may be.

C. Wherever possible each provision of this Agreement shall be interpreted
in such manner as to be effective and valid under applicable law, but if any
such provision shall be prohibited by or invalid under applicable law, it shall
be ineffective only to the extent of such prohibition or invalidity, without
invalidating the remainder of such provision or the remaining provisions of this
