ITEM 20.  INDEMNIFICATION OF DIRECTORS AND OFFICERS

    Article V of the Registrant's Articles of Incorporation provides that the
liability of the directors of the corporation for monetary damages shall be
eliminated to the fullest extent permissible under California law. Article VI of
the Registrant's Articles of Incorporation provides that the corporation is

that expressly permitted by such Section 317 for breach of duty to the
corporation and its shareholders to the fullest extent permissible under
California law.

    Article III of the Registrant's Bylaws provides, in pertinent part, that
each person who is or was a director, officer, employee or agent of the
corporation, or is or was serving at the request of the corporation as a
director, officer, employee or agent of another foreign or domestic corporation
or other entity, shall be indemnified by the Registrant to the full extent
permitted by the General Corporation Law of the State of California or any other
applicable laws. Article III also authorizes the registrant to enter into one or
more agreements with any person which provides for indemnification greater or
different than that provided for in that Article.

    The Registrant has entered into an indemnification agreement with its
Chairman and Chief Executive Officer on the forms incorporated by reference as

ITEM 22.  UNDERTAKINGS

    (a) The undersigned registrant hereby undertakes:

    1.  To file, during any period in which offers or sales are being made, a
       post-effective amendment to this registration statement:

        (i) To include any prospectus required by Section 10(a)(3) of the
            Securities Act;

        (ii) To reflect in the prospectus any facts or events arising after the
             effective date of the registration statement (or the most recent
             post-effective amendment thereof) which, individually or in the
             aggregate, represent a fundamental change in the information set
             forth in the registration statement;

       (iii) To include any material information with respect to the plan of
             distribution not previously disclosed in the registration statement
             or any material change to such information in the registration
             statement.

    2.  That, for the purpose of determining any liability under the Securities
       Act of 1933, each such post-effective amendment shall be deemed to be a
       new registration statement relating to the securities offered therein,
       and the offering of such securities at that time shall be deemed to be
       the initial bona fide offering thereof.

                                      II-3
<PAGE>
    3.  To remove from registration by means of a post-effective amendment any
       of the securities being registered which remain unsold at the termination
       of the offering.

    (b)(1)The undersigned registrant hereby undertakes as follows: That prior to
any public reoffering of the securities registered hereunder through use of a
prospectus which is a part of this registration statement, by any person or
party who is deemed to be an underwriter within the meaning of Rule 145(c), the
issuer undertakes that such reoffering prospectus will contain the information
called for by the applicable registration form with respect to reofferings by
persons who may be deemed underwriters, in addition to the information called
for by the other Items of the applicable form.

    (2) The registrant undertakes that every prospectus (i) that is filed
pursuant to paragraph (h)(1) immediately preceding, or (ii) that purports to
meet the requirements of section 10(a)(3) of the Act and is used in connection
with an offering of securities subject to Rule 415 (Section 230.415 of this
chapter), will be filed as a part of an amendment to the registration statement
and will not be used until such amendment is effective, and that, for purposes
of determining any liability under the Securities Act of 1933, each such
post-effective amendment shall be deemed to be a new registration statement
relating to the securities offered therein, and the offering of such securities
at that time shall be deemed to be the initial bona fide offering thereof.

    (c) Insofar as indemnification for liabilities arising under the Securities
Act of 1933 may be permitted to directors, officer and controlling persons of
the registrant pursuant to the foregoing provisions, or otherwise, Pacific
Community Banking Group has been advised that in the opinion of the Securities
and Exchange Commission such indemnification is against public policy as
expressed in the Act and is, therefore, unenforceable. In the event that a claim
for indemnification against such liabilities (other than the payment by the
registrant of expenses incurred or paid by a director, officer or controlling
person of the registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the registrant will, unless in
the opinion of its counsel the matter has been settled by controlling precedent,
submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Act and will
be governed by the final adjudication of such issue.

    (d) The undersigned registrant hereby undertakes to respond to requests for
information that is incorporated by reference into the joint proxy
statement/prospectus pursuant to Item 4 of this form, within one business day of
receipt of such request, and to send the incorporated documents by first class
mail or other equally prompt means. This includes information contained in
documents filed subsequent to the effective date of the Registration Statement
through the date of responding to the request.

    (e) The undersigned registrant hereby undertakes to supply by means of a
post-effective amendment all information concerning a transaction, and the
company being acquired involved therein, that was not the subject of and
included in the registration statement when it became effective.

    Enclosed is a set of shareholder documents. Please read these documents
carefully. Please complete and return these documents to U.S. Stock Transfer,
which is the exchange agent and custodian in the proposed acquisition of The
Bank of Hemet by Pacific Community Banking Group. Or if you received these

instructions for completing the forms begin on page three, preceded by
frequently asked questions and answers. When the acquisition is completed, we
will need these documents to ensure you promptly receive certificates for your
new shares of Pacific Community Banking Group Common Stock and warrants, and so
that you can participate in the initial public offering of Pacific Community

    - PLEASE USE THE ENCLOSED PINK BUSINESS RETURN ENVELOPES FOR YOUR PROXY CARD
      ONLY.

    - USE THE WHITE RETURN ENVELOPES TO RETURN THE SIGNED SHAREHOLDER DOCUMENTS
      AND YOUR STOCK CERTIFICATES BY CERTIFIED MAIL IN SEPARATE ENVELOPES.

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

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

A:  Pacific Community Banking Group has agreed to acquire The Bank of Hemet. You
    have received a proxy statement/prospectus that describes Pacific Community
    Banking Group and the acquisition. If the shareholders approve the
    acquisition, The Bank of Hemet 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 The Bank of Hemet common stock. In exchange
    for each share so surrendered you will receive 3.4 shares of Pacific
    Community Banking Group common stock and one warrant for the purchase of one
    share of Pacific Community Banking Group common stock. 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, James B. Jaqua and John J. McDonough, to act in this capacity. They
    will negotiate the final price to the public of the shares of Pacific
    Community

                                       2
<PAGE>
    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 cash or 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 stock,
    it is likely that most of your shares will be sold because the acquisition
    agreement requires that the underwriters purchase and resell between 75% and
    88% of the total shares received by shareholders of The Bank of Hemet.
    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 The Bank of Hemet
    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 your 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 The Bank of
    Hemet 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.

                                       3
<PAGE>
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' fees and all
    other costs of reselling your shares in the public offering. You will
    receive the public offering price for each share that you sell in the public
    offering, without deduction for any costs.

                                  INSTRUCTIONS

Ladies and Gentlemen:

    The undersigned (the "Shareholder") is a shareholder of The Bank of Hemet
("The Bank of Hemet"), a California corporation. Pacific Community Banking
Group, a California corporation, and The Bank of Hemet have signed a First
Restatement of Agreement and Plan of Reorganization (as amended, the
"Acquisition Agreement") providing for the acquisition of The Bank of Hemet by
Pacific Community Banking Group. If the acquisition is completed, the
Shareholder's shares of The Bank of Hemet will automatically convert into a
right to receive shares of Pacific Community Banking Group. Pacific Community
Banking Group and the Shareholder proposes 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

                                       1
<PAGE>

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 The Bank of
Hemet 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 James B. Jaqua and
John J. McDonough (the "Attorneys-in-Fact"), and each of them, its agent and
attorney-in-fact, with full power of substitution, with respect to all matters
arising in connection with the public offering and sale of the Shares,
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:

    (i) to instruct the Custodian (as defined below) to surrender certificates
        for all of the Shareholders' shares of common stock of The Bank of Hemet
        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
         TO THE TOTAL NUMBER OF SHARES OF PACIFIC COMMUNITY BANKING STOCK OWNED
         BY THE SHAREHOLDER.

    (v) to sell, assign, transfer and deliver the Shares to the Underwriters and
        deliver to the Underwriters certificates for the Shares so sold;

    (vi) take any and all steps deemed necessary or desirable by the
         Attorneys-in-Fact in connection with the registration of the Shares
         under the Securities Act of 1933, as amended (the "Securities Act"),
         the Securities Exchange Act of 1934, as amended, and under the
         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;

   (vii) instruct Pacific Community Banking Group and the Custodian (as
         hereinafter defined) on all matters pertaining to the sale of the
         Shares and delivery of certificates therefor; and

  (viii) otherwise take all actions and do all things necessary or proper,
         required, contemplated or deemed advisable or desirable by the
         Attorneys-in-Fact in their discretion, including the

                                       2
<PAGE>
         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
of any Attorney-in-Fact shall be the act of the Attorneys-in-Fact. Each
Attorney-in-Fact is hereby empowered to determine, in his sole and absolute
discretion, the time or times when, the purposes for which, and the manner in
which, any power herein conferred upon the Attorneys-in-Fact shall be exercised.

    C.  The Custodian, the Representatives, Pacific Community Banking Group and
all other persons dealing with the Attorneys-in-Fact as such may rely and act
upon any writing believed in good faith to be signed by one or more of the
Attorneys-in-Fact.

    D.  The Attorneys-in-Fact shall not receive any compensation from the
Shareholder for their services rendered hereunder.

    2.  APPOINTMENT OF CUSTODIAN; DEPOSIT OF SHARES.

    A.  In connection with and to facilitate the exchange of shares of The Bank
of Hemet common stock and the sale of the Shares to the Underwriters, the
Shareholder hereby appoints U.S. Stock Transfer Corporation as custodian (the
"Custodian") and herewith deposits with the Custodian one or more certificates
for The Bank of Hemet common stock which represent the total number of the
shares of The Bank of Hemet common stock held by the Shareholder, and which
number is set forth on Schedule I hereto. Each such certificate so deposited is
in negotiable and proper deliverable form and either (a) the certificate has
been endorsed in blank with the signature of the Shareholder thereon, medallion
guaranteed by an eligible guarantor institution, such as a bank, a stock broker,
savings and loan association, or credit union, with membership in an approved
medallion signature program, or (b) the shareholder has separately provided a
duly executed stock power or powers in blank, bearing the signature of the
Shareholder, medallion guaranteed in the same manner. The Custodian is hereby
authorized and directed, subject to the instructions of the Attorneys-in-Fact,
to act as follows:

    (i) to surrender the certificates for Shareholder's shares of The Bank of
        Hemet in exchange for certificates of Pacific Community Banking Group
        common stock in accordance with the Acquisition Agreement;

    (ii) to hold in custody the certificate or certificates deposited herewith
         and any other certificates or instruments exchanged therefor;

   (iii) to deliver or to authorize Pacific Community Banking Group's transfer
         agent to deliver the certificates of Pacific Community Banking Group
         common stock received in exchange for the certificates deposited
         herewith (or replacement certificate(s) for the Shares) to or at the
         direction of the Attorneys-in-Fact; and

    (iv) to return or cause Pacific Community Banking Group's transfer agent to
         return to the Shareholder cash in lieu of fractional shares and new
         certificate(s) for the shares of Pacific Community Banking Group common
         stock and warrants that are received in exchange for any certificate
         deposited hereunder but that are not sold to the Underwriters.

    B.  Until the shares of The Bank of Hemet common stock deposited hereunder
have been exchanged for Pacific Community Banking Group common stock, the
Shareholder shall retain all rights of ownership with respect to the shares of
The Bank of Hemet common stock deposited hereunder, including the right to vote
and to receive all dividends and payments thereon, except the right to retain
custody of or dispose

                                       3

been delivered to the Underwriters against payment therefor, the Shareholder
shall retain all rights of ownership with respect to the Shares, including the
right to vote and to receive all dividends and payment thereon, except the right
to retain custody of or dispose of such Shares, which right is subject to this
Agreement.

Pacific Community Banking Group, the Attorneys-in-Fact and the Custodian as
follows:

    A.  The Shareholder has full legal right, power and authority to enter into
and perform this Agreement. This Agreement has been duly executed and delivered
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,
insolvency, reorganization, moratorium or other laws of general application
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 or 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

                                       4
<PAGE>

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
to sell, assign, transfer and deliver the shares of The Bank of Hemet common
stock to 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 The Bank of Hemet 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 owner of and will have good and marketable title to the Shares free
and clear of 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
Community Banking Group, or which has constituted or which might in the future
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
not named as an owner on the stock certificate, the Shareholder is enclosing
with this Agreement a duly completed and executed consent of his or her spouse,
in the form attached to this Agreement as Annex A.

    F.  The Shareholder agrees to deliver to the Attorneys-in-Fact such
documentation as the Attorneys-in-Fact, The Bank of Hemet, Pacific Community
Banking 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.

    G.  The foregoing representations, warranties and agreements are made for
the benefit of, and may be relied upon by, the Attorneys-in-Fact, The Bank of
Hemet, Pacific Community Banking Group, the Custodian, the Underwriters and
their respective representatives, agents and counsel.

    7.  IRREVOCABILITY OF INSTRUMENTS; TERMINATION OF THIS AGREEMENT.

    A.  This Agreement, the deposit of The Bank of Hemet common stock pursuant
hereto and all authority hereby conferred, is granted, made and conferred

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

<PAGE>

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
completed by August 4, 1999, this Agreement shall terminate (without affecting
any lawful action of the Attorneys-in-Fact or the Custodian prior to such
termination), unless extended by one or both of the Attorneys-in-Fact, and the
Attorneys-in-Fact shall cause the Custodian to return to the Shareholder all
certificates for The Bank of Hemet common stock deposited hereunder.

    8.  LIABILITY AND INDEMNIFICATION OF THE ATTORNEYS-IN-FACT AND CUSTODIAN.

Group common stock exchanged therefor, the proceeds from the sale of the Shares
and any other shares of Pacific Community Banking Group common stock deposited
with the Custodian pursuant to the terms of this Agreement in accordance with

             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

                                       2
<PAGE>

    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.

                                       3
<PAGE>

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.

                                  INSTRUCTIONS

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

                                       1
<PAGE>

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
arising in connection with the public offering and sale of the Shares,
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:

    (i) to instruct the Custodian (as defined below) to surrender certificates
        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
         TO THE TOTAL NUMBER OF SHARES OF PACIFIC COMMUNITY BANKING STOCK OWNED
         BY THE SHAREHOLDER.

    (v) to sell, assign, transfer and deliver the Shares to the Underwriters and
        deliver to the Underwriters certificates for the Shares so sold;

    (vi) take any and all steps deemed necessary or desirable by the
         Attorneys-in-Fact in connection with the registration of the Shares
         under the Securities Act of 1933, as amended (the "Securities Act"),
         the Securities Exchange Act of 1934, as amended, and under the
         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;

   (vii) instruct Pacific Community Banking Group and the Custodian (as
         hereinafter defined) on all matters pertaining to the sale of the
         Shares and delivery of certificates therefor; and

  (viii) otherwise take all actions and do all things necessary or proper,
         required, contemplated or deemed advisable or desirable by the
         Attorneys-in-Fact in their discretion, including the

                                       2
<PAGE>

         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
of any Attorney-in-Fact shall be the act of the Attorneys-in-Fact. Each
Attorney-in-Fact is hereby empowered to determine, in his sole and absolute
discretion, the time or times when, the purposes for which, and the manner in
which, any power herein conferred upon the Attorneys-in-Fact shall be exercised.

    C.  The Custodian, the Representatives, Pacific Community Banking Group and
all other persons dealing with the Attorneys-in-Fact as such may rely and act
upon any writing believed in good faith to be signed by one or more of the
Attorneys-in-Fact.

    D.  The Attorneys-in-Fact shall not receive any compensation from the
Shareholder for their services rendered hereunder.

    2.  APPOINTMENT OF CUSTODIAN; DEPOSIT OF SHARES.

    A.  In connection with and to facilitate the exchange of shares of Valley
Bank common stock and the sale of the Shares to the Underwriters, the
Shareholder hereby appoints U.S. Stock Transfer Corporation as custodian (the
"Custodian") and herewith deposits with the Custodian one or more certificates
for Valley Bank common stock which represent the total number of the shares of
Valley Bank common stock held by the Shareholder, and which number is set forth
on Schedule I hereto. Each such certificate so deposited is in negotiable and
proper deliverable form and either (a) the certificate has been endorsed in
blank with the signature of the Shareholder thereon, medallion guaranteed by an
eligible guarantor institution, such as a bank, a stock broker, savings and loan
association, or credit union, with membership in an approved medallion signature
program, or (b) the Shareholder has separately provided a duly executed stock
power or powers in blank, bearing the signature of the Shareholder, medallion
guaranteed in the same manner. The Custodian is hereby authorized and directed,
subject to the instructions of the Attorneys-in-Fact, to act as follows:

    (i)  to surrender the certificates for Shareholder's shares of Valley Bank
         in exchange for certificates of Pacific Community Banking Group common
         stock in accordance with the Acquisition Agreement;

    (ii) to hold in custody the certificate or certificates deposited herewith
         and any other certificates or instruments exchanged therefor;

   (iii) to deliver or to authorize Pacific Community Banking Group's transfer
         agent to deliver the certificates of Pacific Community Banking Group
         common stock received in exchange for the certificates deposited
         herewith (or replacement certificate(s) for the Shares) to or at the
         direction of the Attorneys-in-Fact; and

    (iv) to return or cause Pacific Community Banking Group's transfer agent to
         return to the Shareholder cash in lieu of fractional shares and new
         certificate(s) for the shares of Pacific Community Banking Group common
         stock and warrants that are received in exchange for any certificate
         deposited hereunder but that are not sold to the Underwriters.

    B.  Until the shares of Valley Bank common stock deposited hereunder have
been exchanged for Pacific Community Banking Group common stock, the Shareholder
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
dividends and payments thereon, except the right to retain custody of or dispose
of such Shares,

                                       3
<PAGE>

which right is subject to this Agreement. Until the Shares have been delivered
to the Underwriters against payment therefor, the Shareholder shall retain all
rights of ownership with respect to the Shares, including the right to vote and
to receive all dividends and payment thereon, except the right to retain custody
of or dispose of such Shares, which right is subject to this Agreement.

    3.  IRREVOCABLE OFFER TO SELL SHARES OF PACIFIC COMMUNITY BANKING GROUP
     COMMON STOCK.

    The Shareholder offers for sale to the Underwriters any and all shares of
Pacific Community Banking Group common stock received in exchange for the shares
of Valley Bank common stock transmitted herewith. This offer is made without
conditions, except as provided in this Agreement, and may be accepted and
executed without prior notice to the Shareholder. The Shareholder may not revoke
this offer; however, this offer will expire if not accepted in whole or in part
by the Underwriter on or before August 4, 1999, unless extended by one or both
of the Attorneys-in-Fact.

    4.  PREFERENCE TO RECEIVE CASH OR SHARES OF PACIFIC COMMUNITY BANKING GROUP
     COMMON STOCK

    The Shareholder hereby instructs the Attorney-in-Fact that the shareholder
prefers to receive consideration for the surrendered shares of Valley Bank
common stock as indicated on the Statement of Preference attached to this
Agreement. The Shareholder acknowledges that this preference is subject to the
power of the Attorney-in-Fact to allocate the number of Shareholders' shares
sold to the Underwriters to satisfy the terms of the Acquisition Agreement, in
the sole discretion of the Attorney-in-Fact.

    5.  SALE OF SHARES; REMITTING NET PROCEEDS.

    The Attorneys-in-Fact are hereby authorized and directed to deliver or cause
the Custodian or Pacific Community Banking Group's transfer agent to deliver
certificates for the Shares to the Representatives, against delivery to the
Attorneys-in-Fact, for the account of the Shareholder, of the purchase price of
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
Custodian shall promptly remit to the Shareholder his or her share of the
proceeds.

    6.  REPRESENTATIONS, WARRANTIES AND AGREEMENTS.

    To induce the Underwriters to enter into an underwriting agreement with
Pacific Community Banking Group and certain of its shareholders, and in

Group common stock exchanged therefor, the proceeds from the sale of the Shares
and any other shares of Pacific Community Banking Group common stock deposited
with the Custodian pursuant to the terms of this Agreement in accordance with
the provisions hereof. The Shareholder hereby agrees to indemnify and hold
harmless the Attorneys-in-Fact and the Custodian, and their respective officers,
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.

    9.  INTERPRETATION.

                              OPTION HOLDER DOCUMENTS

Q:   I AM AN OPTION HOLDER OF THE BANK OF HEMET.  WHY MUST I COMPLETE THESE
     DOCUMENTS?

A:   Pacific Community Banking Group has agreed to acquire The Bank of Hemet.
     The accompanying proxy statement/prospectus describes the acquisition,
     including the rights of option holders.  Your options will all expire if
     you do not return the Option Cancellation Agreement and the shareholders
     approve the acquisition.  The Bank of Hemet needs the option holder
     documents to arrange for you to receive any cash, stock and warrants you
     will be entitled to receive.

Q:   WHAT IF MY OPTIONS HAVEN'T VESTED?

A:   All of your options will be treated as vested for purposes of cancellation
     and exchange in the acquisition.

Q:   WHAT IS THE OPTION CANCELLATION AGREEMENT?

A:   The Option Cancellation Agreement cancels your options in exchange for a
     right to receive common stock and warrants of Pacific Community Banking
     Group.  The common stock may be sold in the public offering subject to the
     limitations described below. IF YOU DO NOT COMPLETE AND RETURN THIS
     AGREEMENT IN TIME, YOUR OPTIONS WILL SIMPLY EXPIRE WHEN THE ACQUISITION IS
     COMPLETE.

Q:   HOW MUCH STOCK AND WARRANTS WILL I RECEIVE?

A:   You will receive a number of shares of Pacific Community Banking Group
     Stock as follows:

           3.4 x ($51 minus the exercise price of the option)
           --------------------------------------------------
                                 $51

     You will receive one warrant for each 3.4 shares of Pacific Community
     Banking Group common stock you receive.  The terms of the warrants are
     described in the proxy statement/prospectus.  You will receive more cash
     for shares sold if the price of Pacific Community Banking Group common
     stock in the initial public offering is more than $15.00.  You will receive
     cash instead of fractional shares. No fractional warrants shall be issued.

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

A:   You should read the entire document, which is necessary for you to sell any
     of your new shares of Pacific Community Banking Group common stock in the
     offering.  In summary,

                                         2

          entitled in exchange for your options, 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 options 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.

     -    You appoint custodians of your new Pacific Community Banking Group
          common stock and 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, James B. Jaqua and John J. McDonough, 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
     sign any documents necessary to complete the sale, on your behalf, without
     further consultation with you.

Q:   WHO ARE THE CUSTODIANS AND WHAT WILL THE CUSTODIANS DO?

A:   James B. Jaqua and John J. McDonough will be the custodians.  They will
     keep custody of your new shares of Pacific Community Banking Group Common
     Stock for the brief period until the public offering closes, then deliver
     shares you sell to the underwriter, send The Bank of Hemet the money
     received from the sale (which The Bank of Hemet will in turn deliver to
     you), and instruct the transfer agent to send you certificates for the
     shares you don't sell and certificates for your warrants.

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 cash or stock of
     Pacific

                                         3
<PAGE>


     Community Banking Group or a combination of the two 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 stock, it is likely that most of your shares will
     be sold because the acquisition agreement requires that the underwriters
     purchase and resell between 75% and 88% of the total shares received by
     shareholders and option holders of The Bank of Hemet.  Similarly, if you
     indicate a preference to receive all cash, you may be required to retain
     some amount of Pacific Community Banking Group common stock.

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

A:   In addition to your name and address, you will give instructions where The
     Bank of Hemet should send the money received from the sale and where the
     Transfer Agent should send any remaining shares and your warrants.  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 THE ACQUISITION OR THE PUBLIC OFFERING IS NOT COMPLETED?

A:   If either the acquisition or the public offering fails to take place, your
     options will not be canceled and will remain in effect under their previous
     terms.

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 in
     the public offering.

Community Banking Group common stock to satisfy the terms of the First
Restatement of the Agreement and Plan of Reorganization between The Bank of
Hemet and Pacific Community Banking Group.  In either case, the Custodians will
cause to be delivered to you in due course, but not earlier than ten days after
the closing for the purchase of firm shares by the Underwriters, a certificate
for the number of shares of Pacific Community Banking Group common stock and
warrants that you have received but that were not sold in the public offering.

THIS AGREEMENT ("Agreement"), dated as of July ___, 1999, is entered into by and
between The Bank of Hemet, a California state chartered banking institution
("Bank"), and _________________________________ ("Optionee").

                                       RECITALS

A.   Bank and Pacific Community Banking Group, a California corporation ("PCBG")
     entered into that First Restatement of Agreement and Plan of Reorganization
     dated as of January 5, 1999 and amended March 24, 1999 and April 2, 1999
     (the "Reorganization Agreement") whereby Bank will be acquired and become a
     wholly owned subsidiary of PCBG.

B.   Optionee currently has stock options ("Options") under The Bank of Hemet
     1994 Stock Option Plan, as set forth in the Exhibit A.

C.   Under the Reorganization Agreement, (a) each share of The Bank of Hemet
     common stock acquirable under the Options shall be canceled by Optionee and
     for each share subject to the Options receive in exchange (i) shares of
     common stock of PCBG equal to (A) 3.4 shares minus (B) the exercise price
     of the Options and (ii) one warrant to acquire one share of common stock of
     PCBG common stock for each 3.4 shares of common stock of PCBG paid by PCBG
     in exchange for options on The Bank of Hemet common stock, (b) there will
     be no fractional warrants issued and no cash paid in lieu of fractional
     warrants, and (c) the Optionee may elect to sell the shares of PCBG common
     stock in the public offering subject to the allocation requirements in the
     Reorganization Agreement.  The amount to be paid to Optionee in cash and/or
     in PCBG common stock for the cancellation of the options pursuant to the
     Reorganization Agreement shall be hereinafter referred to as the "Option
     Consideration."

D.   Optionee desires to cancel his or her Options in exchange for the Option
     Consideration which is computed and set forth in Exhibit B.  Optionee
     further desires to (a) establish the withholding amounts for federal and
     state tax purposes with respect to the payment of the Option Consideration,
     (b) provide payment to the Bank in the event there is insufficient cash
     funds from the Option Consideration to pay the necessary withholdings and
     (c) provide the Bank with an indemnification to the Bank in the event the
     Bank is required to pay withholdings to any governmental agency because
     such amounts were not withheld from the Option Consideration paid to
     Optionee.

E.   Unless otherwise provided in this Agreement, capitalized terms shall have
     the meanings given to them in the Reorganization Agreement.

NOW THEREFORE, in consideration of the premises and of the respective
representations, warranties and covenants, agreements and conditions contained
herein and in the Reorganization Agreement, and intending to be legally bound
hereby, Bank and Optionee agree as follows:

     1.   CANCELLATION OF THE OPTIONS IN EXCHANGE FOR THE OPTION CONSIDERATION.
Optionee  and Bank agree to the cancellation of the Options in exchange for
Option Consideration.

     2.   WITHHOLDING.  Optionee understands that Bank is allowing Optionee to
elect the amount to be withheld from the payment of the Option Consideration for
federal and state income taxes and that such election is not binding on the
Bank.  The Bank may be required by federal and state tax law to withhold a
minimum of 28% for federal tax purposes and 6% for California state tax purposes
from the Option Consideration notwithstanding the election by Optionee.
Optionee understands that the Bank is

                                         6
<PAGE>

required by federal and state law to withhold additional amounts for other
purposes including Medicare, Social Security and SDI.

Optionee, to extent allowed, elects to have the following percentages of the
total Option Consideration withheld.

                          Federal Income Tax Withheld _____%

                         California Income Tax Withheld_____%

If no election is made, the minimum withholding rates of 28% for Federal income
taxes and 6% for California income taxes will be used.

In the event the cash consideration portion of the Option Consideration is
insufficient to pay the minimum aggregate withholding amount ("Withholding
Amount') for the Option Consideration as determined by the Bank, Optionee
further agrees to pay the difference ("Difference") between the Withholding
Amount and the cash consideration portion of the Option Consideration to the
Bank.  Optionee understands that payment of the Option Consideration to Optionee
is subject to Optionee prior payment to the Bank of the Difference.

     3.   HOLD HARMLESS AND INDEMNIFICATION.  Optionee agrees to hold the Bank
harmless from any liability, losses, costs, damages or attorney's fees for any
action taken by the Bank with respect to complying with the Optionee's election
as to the amount of withholding in Section 2 of this Agreement.  Optionee agrees
to indemnify Bank for any and all costs including any amounts that should have
been withheld from the Option Consideration, expenses, damages and attorney's
fees incurred by the Bank arising from any action taken by the Bank with respect
to complying with Optionee's election under Section 2 of this Agreement.

     4.   GOVERNING LAW.  This Agreement is governed by and is to be construed
and enforced in accordance with the laws of the State of California.  If under
such law, any portion of this Agreement is at any time deemed to be in conflict
with any applicable statute, rule, regulation or ordinance, such portion shall
be deemed to be modified or altered to conform thereto or, if that is not
possible, to be omitted from this Agreement; the invalidity of any such portion
shall not affect the force, effect and validity of the remaining portion hereof.

     5.   TERMINATION.  If the transactions contemplated in the Reorganization
Agreement are not completed, the Options shall not be cancelled and shall remain
in full force and effect, and subject to their original terms and conditions.

     6.   ENTIRE AGREEMENT.  This Agreement constitutes the entire understanding
among Bank, PCBG and Optionee with respect to the subject matter hereof and
supersedes and cancels all prior written and oral agreements and understandings
with respect to the subject matter of this Agreement.  This Agreement may be
amended but only by a subsequent written agreement of the parties.

     7.   EFFECT OF AGREEMENT.  In the event that the Reorganization Agreement
is terminated, this Agreement shall automatically terminate.

     8.   DISPUTE RESOLUTION.   Any dispute regarding this Agreement shall only
be heard and resolved in a court of competent jurisdiction located in the County
of Riverside, California.

     9.   LEGAL COSTS.  If either party commences an action against the other
party arising or in connection with this Agreement, the prevailing party shall
be entitled to have and recover from the losing party reasonable attorney's fees
and costs of suit.

Ladies and Gentlemen:

     The undersigned (the "Option Holder") holds options to purchase the
common stock of The Bank of Hemet ("The Bank of Hemet"), a California
corporation. Pacific Community Banking Group, a California corporation, and
The Bank of Hemet have signed a First Restatement of Agreement and Plan of
Reorganization (as amended, the "Acquisition Agreement") providing for the
acquisition of The Bank of Hemet by Pacific Community Banking Group. If the
acquisition is completed, the Option Holder's shares of The Bank of Hemet
will automatically convert into a right to receive shares of Pacific
Community Banking Group. Pacific Community Banking Group and the Option
Holder proposes to sell some or all of the shares of Pacific Community
Banking Group common stock received by the Option Holder 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 Option Holder in
exchange for shares of The Bank of Hemet common stock, all of which the
Option Holder will hereby offer to sell to the Underwriters, are referred to
herein as the "Shares."

     A.  The Option Holder irrevocably constitutes and appoints James B. Jaqua

attorney-in-fact, with full power of substitution, with respect to all matters
arising in connection with the public offering and sale of the Shares,
including, but not limited to, the power and authority on behalf of the Option
Holder to do or cause to be done any of the following things:

     (i)    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;

     (ii)   to execute on behalf of the Option Holder an underwriting agreement
            as follows: (a) making the representations and warranties of the
            Option Holder contained in this Agreement to the Underwriters; (b)
            undertaking the obligations of the Option Holder contained in this
            agreement, for the benefit of the Underwriters; and (c) indemnifying
            the Underwriters, on a joint and several basis with Pacific

            Pacific Community Banking Group, for losses resulting from a breach
            of those representations, warranties and obligations, up to the
            amount of consideration received by the Option Holder 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, provided the underwriters
            have a reciprocal obligation to the shareholders of Pacific
            Community Banking Group participating in the public offering.

     (iii)  to allocate the number of shares of Pacific Community Banking Group
            common stock owned by the Option Holder 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 Option Holder, in
            satisfaction of the terms of the Acquisition Agreement.
            NOTWITHSTANDING THE STATEMENT OF PREFERENCE MADE BY THE OPTION
            HOLDER HEREIN, THE ATTORNEYS-IN-FACT ARE AUTHORIZED, IN THEIR SOLE

     (iv)   to sell, assign, transfer and deliver the Shares to the Underwriters
            and deliver to the Underwriters certificates for the Shares so sold;

     (v)    take any and all steps deemed necessary or desirable by the
            Attorneys-in-Fact in connection with the registration of the Shares
            under the Securities Act of 1933, as amended (the "Securities Act"),

            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;

     (vi)   instruct Pacific Community Banking Group and the Custodian (as
            hereinafter defined) on all matters pertaining to the sale of the
            Shares and delivery of certificates therefor; and

     (viii) otherwise take all actions and do all things necessary or proper,
            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 Option Holder with respect to the sale of the Shares to the

     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
of any Attorney-in-Fact shall be the act of the Attorneys-in-Fact. Each
Attorney-in-Fact is hereby empowered to determine, in his sole and absolute
discretion, the time or times when, the purposes for which, and the manner in
which, any power herein conferred upon the Attorneys-in-Fact shall be exercised.

     3.  IRREVOCABLE OFFER TO SELL SHARES OF PACIFIC COMMUNITY BANKING GROUP
COMMON STOCK.

     The Option Holder offers for sale to the Underwriters any and all shares
of Pacific Community Banking Group common stock received upon cancellation of
options to purchase stock of The Bank of Hemet as provided in the Option
Cancellation Agreement.  This offer is made without conditions, except as
provided in this Agreement, and may be accepted and executed without prior
notice to the Option Holder. The Option Holder may not revoke this offer;
however, this offer will expire if not accepted in whole or in part by the
Underwriters on or before August 4, 1999, unless extended by one or both of
the Attorneys-in-Fact.

     4.  PREFERENCE TO RECEIVE CASH OR SHARES OF PACIFIC COMMUNITY BANKING
GROUP COMMON STOCK.

     The Option Holder hereby instructs the Attorneys-in-Fact that the
shareholder prefers to receive consideration for the cancelled options of The
Bank of Hemet common stock as indicated on the Statement of Preference
attached in this Agreement. The Option Holder acknowledges that this
preference is subject to the power of the Attorneys-in-Fact to allocate the
number of Option Holders' shares sold to the Underwriters to satisfy the
terms of the Acquisition Agreement, in the sole discretion of the
Attorneys-in-Fact.

     5.  SALE OF SHARES; REMITTING NET PROCEEDS.

     The Attorneys-in-Fact are hereby authorized and directed to deliver or
cause the Custodians or Pacific Community Banking Group's transfer agent to
deliver certificates for the Shares to the Representatives, against delivery
to the Attorneys-in-Fact, for the account of the Option Holder, of the
purchase price of the Shares. The Attorneys-in-Fact are authorized, on behalf
of the Option Holder, to accept and acknowledge receipt of the payment of the
purchase price for the Shares and shall promptly deposit such proceeds with
the Custodians. The Custodians shall promptly remit to the Option Holder his
or her share of the proceeds, less taxes and other withholdings withheld
pursuant to Section 2 of the Option Cancellation Agreement.

     6.  REPRESENTATIONS, WARRANTIES AND AGREEMENTS.

     To induce the Underwriters to enter into an underwriting agreement with
Pacific Community Banking Group and certain of its shareholders, and in
consideration of the performance of this Agreement by the other parties
thereto, the Option Holder represents and warrants to, and agrees with, the
Underwriters, Pacific Community Banking Group, the Attorneys-in-Fact and the
Custodians as follows:

     A.  The Option Holder has full legal right, power and authority to enter
into and perform this Agreement. This Agreement has been duly executed and
delivered by the Option Holder and (assuming this Agreement is a binding
Agreement of the other parties thereto) constitutes the valid and binding
agreement of the Option Holder, enforceable against the Option Holder in
accordance with its terms (except as such enforceability may be limited by
applicable bankruptcy, insolvency, reorganization, moratorium or other laws
of general application 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 or affecting the enforcement
of creditors' rights 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

                                     16

<PAGE>

indenture, mortgage, deed or trust, voting trust agreement, shareholders'
agreement, note agreement or other agreement or instrument to which the
Option Holder is a party or by which the Option Holder 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 Option Holder of any
government, arbitrator, court, regulatory body or administrative agency or
other governmental agency or body, domestic or foreign, having jurisdiction
over the Option Holder or any of his activities or properties.

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

     D.  To the Option Holder's knowledge, the Option Holder has not taken
any action designed to stabilize or manipulate the price of any security of
Pacific Community Banking Group, or which has constituted or which might in
the future 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 Option Holder is an individual and is married, and the spouse
is not named as an owner on the option agreement, the Option Holder is
enclosing with this Agreement a duly completed and executed consent of his or
her spouse, in the form attached to this Agreement as Annex A.

     F.  The Option Holder agrees to deliver to the Attorneys-in-Fact such
documentation as the Attorneys-in-Fact, The Bank of Hemet, Pacific Community
Banking 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.

     G.  The foregoing representations, warranties and agreements are made
for the benefit of, and may be relied upon by, the Attorneys-in-Fact, The
Bank of Hemet, Pacific Community Banking Group, the Custodian, the
Underwriters and their respective representatives, agents and counsel.

     7.  IRREVOCABILITY OF INSTRUMENTS; TERMINATION OF THIS AGREEMENT.

     A.  This Agreement, the deposit of Pacific Community Banking Group
common stock pursuant hereto and all authority hereby conferred, is granted,
made and conferred subject to and in consideration of (a) the interests of
the Attorneys-in-Fact, the Underwriters, The Bank of Hemet and Pacific
Community Banking Group in and for the purpose of completing the transactions
contemplated hereunder and by the Acquisition Agreement and the Underwriting
Agreement between Pacific Community Banking Group, certain other selling

estate, right, title and interest in and to the Shares deposited herewith for
the purpose of irrevocably empowering and securing to them 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

                                     17

<PAGE>

force and effect until that date, which may be extended by either or both of
the Attorneys-in-Fact.  The Option Holder 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
Option Holder.  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 Option Holder 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 completed by August 4, 1999, this Agreement shall terminate (without
affecting any lawful action of the Attorneys-in-Fact or Custodians prior to
such termination) unless extended by either or both of the Attorneys-in-Fact.


     8.  LIABILITY AND INDEMNIFICATION OF THE ATTORNEYS-IN-FACT AND CUSTODIAN.

     The Attorneys-in-Fact and the Custodians assume no responsibility or
liability to the Option Holder or to any other person, other than to deal
with the Pacific Community Banking Group common stock exchanged on
cancellation of the Option Holder's options to purchase common stock of The
Bank of Hemet, the proceeds from the sale of the Shares and any other shares
of Pacific Community Banking Group common stock deposited with the Custodians
pursuant to the terms of this Agreement in accordance with the provisions
hereof. The Option Holder hereby agrees to indemnify and hold harmless the
Attorneys-in-Fact and the Custodians, and their respective officers, 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.

     9.  INTERPRETATION.

     A.  The representations, warranties and agreements of the Option Holder
contained herein shall survive the sale and delivery of the Shares and the
termination of this Agreement.

     B.  The validity, enforceability, interpretation and construction of
this Agreement shall be determined in accordance with the laws of the State
of California applicable to contracts made and to be performed within the
State of California, and this Agreement shall inure to the benefit of, and be
binding upon, the Option Holder and the Option Holder'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 Agreement.

     D.  The use of the masculine gender in this Agreement includes the
feminine and neuter, and the use of the singular includes the plural,
wherever appropriate.

                                   JULY 13, 1998

Dear Option Holder:

     Enclosed is a set of documents for option holders of Valley Bank. Please
read these documents carefully.  Please complete and return these documents to
Mr. Marion  V. Ashley and Mr. N. Douglas Mills, the attorneys-in-fact for Valley
Bank, at the Moreno Valley office of Valley Bank.  Detailed instructions for
completing the forms begin on page three, preceded by frequently asked questions
and answers.   When the acquisition is completed, we will need these documents
to ensure that you promptly receive certificates for your new shares of Pacific
Community Banking Group.

              QUESTIONS AND ANSWERS FOR OPTION HOLDERS OF VALLEY BANK

                                     ABOUT THE

                              OPTION HOLDER DOCUMENTS

Q:   I AM AN OPTION HOLDER OF VALLEY BANK.  WHY MUST I COMPLETE THESE DOCUMENTS?


A:   Pacific Community Banking Group has agreed to acquire Valley Bank.  The
     accompanying proxy statement/prospectus describes the acquisition,
     including the rights of option holders.  Your options will all expire if
     you do not return the Option Cancellation Agreement and the shareholders
     approve the acquisition.  Valley Bank needs the remaining option holder
     documents to complete the acquisition and to arrange for you to receive any
     cash, stock and warrants you will be entitled to receive.

Q:   WHAT IF MY OPTIONS HAVEN'T VESTED?

A:   All of your options will be treated as vested for purposes of cancellation
     and exchange in the acquisition.

Q:   WHAT IS THE OPTION CANCELLATION AGREEMENT?

A:   The Option Cancellation Agreement cancels your options in exchange for a
     right to receive common stock and warrants of Pacific Community Banking
     Group.  The common stock may be sold in the public offering subject to the
     limitations described below. IF YOU DO NOT COMPLETE AND RETURN THIS
     AGREEMENT IN TIME, YOUR OPTIONS WILL SIMPLY EXPIRE WHEN THE ACQUISITION IS
     COMPLETE.

Q:   HOW MUCH STOCK AND WARRANTS WILL I RECEIVE?

A:   You will receive a number of shares of Pacific Community Banking Group
     Stock as follows:

     ($10 minus the exercise price of the option)
     --------------------------------------------
                        15

     You will receive one warrant for every two shares of Pacific Community
     Banking Group common stock you receive.  The terms of the warrants are
     described in the proxy statement/prospectus. You will receive more cash for
     shares sold if the price of Pacific Community Banking Group common stock in
     the initial public offering is more than $15.00.  You will receive cash
     instead of fractional shares. No fractional warrants shall be issued.

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

A:   You should read the entire document, which is necessary for you to sell any
     of your new shares of Pacific Community Banking Group common stock in the
     offering.  In summary, the Custody Agreement, Letter of Transmittal, Power
     of Attorney and Offer of Sale is a

                                          2
<PAGE>


     binding agreement by you that principally provides the following:

     -    You provide your name, address and other necessary information to
          ensure that you receive the cash, stock and warrants to which you are
          entitled in exchange for your options, 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 options 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.

     -    You appoint custodians of your new Pacific Community Banking Group
          common stock and 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
     sign any documents necessary to complete the sale, on your behalf, without
     further consultation with you.

Q:   WHO ARE THE CUSTODIANS AND WHAT WILL THE CUSTODIANS DO?

A:   Marion V. Ashley and N. Douglas Mills will also act as custodians.  They
     will keep custody of your new shares of Pacific Community Common Stock for
     the brief period until the public offering closes, then deliver shares you
     sell to the underwriter, send Valley Bank the money received from the sale
     (which Valley Bank will in turn deliver to you), and instruct the transfer
     agent to send you certificates for the shares you don't sell and for your
     warrants.

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 cash or stock or
     a combination thereof of Pacific Community Banking Group after the close of
     the acquisitions and the

                                          3
<PAGE>

     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
     stock, it is likely that most 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 and option holders of
     Valley Bank.  Similarly, if you  indicate a preference to receive all
     cash, you may be required to retain some amount of Pacific Community
     Banking Group common stock.

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

A:   In addition to your name and address, you will give instructions where
     Valley Bank should send the money received from the sale and where the
     transfer agent should send any remaining shares and your warrants.  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 THE ACQUISITION OR THE PUBLIC OFFERING IS NOT COMPLETED?

A:   If either the acquisition or the public offering fails to take place, your
     options will not be canceled and will remain in effect under their previous
     terms.

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 in
     the public offering.

     entered into that First Restatement of Agreement and Plan of Reorganization

<PAGE>


B.   Optionee currently has stock options ("Options") issued under one of the
     Bank's stock option plans, as set forth in Exhibit A.

C.   Under the Reorganization Agreement, (a) the options to acquire shares of
     Valley Bank common stock shall be canceled by Optionee and  the Optionee
     shall receive in exchange (i) shares of common stock of PCBG equal to the
     number of shares of Valley Bank common stock subject to options, multiplied
     by (A) $10.00 minus (B) the exercise price of the Options, all divided by
     $15.00, and (ii) one warrant to acquire one share of common stock of PCBG
     for every two shares of common stock of PCBG issued in accordance with the
     preceding subsection, (b) there will be no fractional warrants issued and
     no cash paid in lieu of fractional warrants, and (c) the Optionee may elect
     to sell the shares of PCBG common stock in the public offering subject to
     the allocation requirements in the Reorganization Agreement.  The amount to
     be paid to Optionee in cash and/or in PCBG common stock for the
     cancellation of the options pursuant to the Reorganization Agreement shall
     be hereinafter referred to as the "Option Consideration."

D.   Optionee desires to cancel his or her Options in exchange for the Option
     Consideration which is computed and set forth in Exhibit B.  Optionee
     further desires to (a) establish the withholding amounts for federal and
     state tax purposes with respect to the payment of the Option Consideration,
     (b) provide payment to the Bank in the event there is insufficient cash
     funds from the Option Consideration to pay the necessary withholdings and
     (c) provide indemnification to the Bank in the event the Bank is required
     to pay withholdings to any governmental agency because such amounts were
     not withheld from the Option Consideration paid to Optionee.

E.   Unless otherwise provided in this Agreement, capitalized terms shall have
     the meanings given to them in the Reorganization Agreement.

NOW THEREFORE, in consideration of the premises and of the respective
representations, warranties, covenants, agreements and conditions contained
herein and in the Reorganization Agreement, and intending to be legally bound
hereby, Bank and Optionee agree as follows:

     1.   CANCELLATION OF THE OPTIONS IN EXCHANGE FOR THE OPTION CONSIDERATION.
Optionee and Bank agree to the cancellation of the Options in exchange for the
Option Consideration.

     2.   WITHHOLDING.  Optionee understands that Bank is allowing Optionee to
elect the amount to be withheld from the payment of the Option Consideration for
federal and state income taxes and that such election is not binding on the
Bank.  The Bank may be required by federal and state tax law to withhold a
minimum of 28% for federal tax purposes and 6% for California state tax purposes
from the Option Consideration notwithstanding the election by Optionee.
Optionee understands that the Bank is required by federal and state law to
withhold additional amounts for other purposes including Medicare, Social
Security and SDI.

Optionee, to extent allowed, elects to have the following percentages of the
total Option Consideration withheld.

                          Federal Income Tax Withheld _____%

                         California Income Tax Withheld_____%

If no election is made, the minimum withholding rates of 28% for Federal income
taxes and 6% for California income taxes will be used.

In the event the cash consideration portion of the Option Consideration is
insufficient to pay the minimum aggregate withholding amount ("Withholding
Amount") for the Option Consideration as determined by the Bank, Optionee
further agrees to pay the difference ("Difference") between the Withholding
Amount

                                          2
<PAGE>

and the cash portion of the Option Consideration to the Bank.  Optionee
understands that payment of the Option Consideration to Optionee is subject to
Optionees' prior payment to the Bank of the Difference.

     3.   HOLD HARMLESS AND INDEMNIFICATION.  Optionee agrees to indemnify and
hold the Bank harmless from any liability, losses, costs including any amounts
that should have been withheld from the Option Consideration,, damages or
attorney's fees for any action taken by the Bank with respect to complying with
the Optionee's election as to the amount of withholding in Section 2 of this
Agreement.

     4.   GOVERNING LAW.  This Agreement is governed by and is to be construed
and enforced in accordance with the laws of the State of California.  If under
such law, any portion of this Agreement is at any time deemed to be in conflict
with any applicable statute, rule, regulation or ordinance, such portion shall
be omitted from this Agreement; the invalidity of any such portion shall not
affect the force, effect and validity of the remaining portion hereof.

     5.   TERMINATION.  If the transactions contemplated in the Reorganization
Agreement are not completed, the Options shall not be cancelled and shall remain
in full force and effect, subject to their original terms and conditions.

     6.   ENTIRE AGREEMENT.  This Agreement constitutes the entire understanding
between Bank and Optionee with respect to the subject matter hereof and
supersedes and cancels all prior written and oral agreements and understandings
with respect to the subject matter of this Agreement.  This Agreement may be
amended only by a subsequent written agreement of the parties.

     7.   EFFECT OF AGREEMENT.  In the event that the Reorganization Agreement
is terminated, this Agreement shall automatically terminate.

     8.   DISPUTE RESOLUTION.   Any dispute regarding this Agreement shall only
be heard and resolved in a court of competent jurisdiction located in the County
of Riverside, California.

     9.   LEGAL COSTS.  If either party commences an action against the other
party arising from or in connection with this Agreement, the prevailing party
shall be entitled to have and recover from the other party reasonable attorneys'
fees and costs of suit.

     10.  SUCCESSORS AND ASSIGNS.  All terms and provisions of this Agreement
shall be binding upon and inure to the benefit of the parties hereto and their
respective transferees, successors and assigns.

IN WITNESS WHEREOF, the parties hereto have executed this Option Cancellation
Agreement as of the year and day first above written.

Ladies and Gentlemen:

     The undersigned (the "Option Holder") holds options to purchase the
common stock 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
Option Holder'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 Option Holder proposes to sell some or all of the
shares of Pacific Community Banking Group common stock received by the Option
Holder 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 Option Holder in exchange for shares of Valley Bank common
stock, all of which the Option Holder will hereby offer to sell to the
Underwriters, are referred to herein as the "Shares."

     A.  The Option Holder 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 arising in connection with the public offering and sale of the
Shares, including, but not limited to, the power and authority on behalf of
the Option Holder to do or cause to be done any of the following things:

     (i)   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;

     (ii)  to execute on behalf of the Option Holder an underwriting agreement
           as follows: (a) making the representations and warranties of the
           Option Holder contained in this Agreement to the Underwriters; (b)
           undertaking the obligations of the Option Holder contained in this
           agreement, for the benefit of the Underwriters; and (c)
           indemnifying the Underwriters, on a joint and several basis with

           of Pacific Community Banking Group, for losses resulting from a
           breach of those representations, warranties and obligations, up to
           the amount of consideration received by the Option Holder 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, provided the
           underwriters have a reciprocal obligation to the shareholders of
           Pacific Community Banking Group participating in the public
           offering.

     (iii) to allocate the number of shares of Pacific Community Banking Group
           common stock owned by the Option Holder 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 Option Holder, in

           agreements and the taking of such other steps as the
           Attorneys-in-Fact may deem necessary or advisable;

     (vi)  instruct Pacific Community Banking Group and the Custodians (as

           the Option Holder with respect to the sale of the Shares to the

proceeds from the sale of the Shares and any other shares of Pacific Community
Banking Group common stock deposited with the Custodians pursuant to the terms
of this Agreement in accordance with the provisions hereof. The Option Holder
hereby agrees to indemnify and hold harmless the Attorneys-in-Fact and the

them in good faith in connection with any and all matters contemplated by this
Agreement or the Underwriting Agreement.
