                               CBES BANCORP, INC.
                            1001 N. Jesse James Road
                        Excelsior Springs, Missouri 64024

                                                                October 28, 2002


Dear Stockholder:


      You are cordially invited to attend a special meeting of stockholders of
CBES Bancorp, Inc. ("CBES"), to be held at the primary location of Community
Bank of Excelsior Springs, a Savings Bank, located at 1001 North Jesse James
Road, Excelsior Springs, Missouri, on December 12, 2002, commencing at 9:00
a.m., local time.


      At this important meeting, stockholders will be asked to consider and vote
upon a proposal to approve a merger agreement under which, among other things,
CBES would enter into a merger resulting in it becoming a wholly-owned
subsidiary of NASB Financial, Inc. ("NASB"). If this merger is completed, you
will receive a cash payment of $17.50 for each share of CBES common stock that
you own, subject to adjustment in certain circumstances (unless you are a
dissenting stockholder who properly demands and perfects your appraisal rights).
On September 5, 2002, the day prior to the date we announced the merger, the
closing price of CBES common stock on the NASDAQ was $13.50 per share. During
the 52-week period immediately preceding that date, CBES common stock traded
within a range having a low price of $12.00 per share and a high price of $15.00
per share.

      If the merger becomes effective, you will no longer own any common stock
or have any ownership interest in CBES, nor will you receive as a result of the
merger any capital stock of NASB or its subsidiaries. In the merger, the
exchange of your shares of CBES common stock for cash generally will cause you
to recognize income for federal income tax purposes and, possibly, state and
local tax purposes. You should consult your personal tax advisor for a full
understanding of the tax consequences of the merger to you.

      Your board of directors has carefully reviewed and considered the terms
and conditions of the proposed merger and has received an opinion of its
financial advisor, Hovde Financial LLC ("Hovde"), that the consideration to be
received by CBES stockholders in the merger is fair from a financial point of
view. THE BOARD OF DIRECTORS OF CBES HAS CONCLUDED THAT THE MERGER IS IN THE
BEST INTERESTS OF CBES AND ITS STOCKHOLDERS, HAS APPROVED THE MERGER AGREEMENT
AND RECOMMENDS THAT THE STOCKHOLDERS APPROVE AND ADOPT SUCH AGREEMENT.

      At the special meeting, you will be asked to approve and adopt the merger
agreement. A majority of the outstanding shares of common stock entitled to vote
thereon must vote for the approval and adoption of the merger agreement for the
merger agreement to be approved by stockholders. If the merger agreement is so
approved, and all other conditions described in the merger agreement have been
satisfied or waived, the merger is expected to become effective in the fourth
quarter of 2002.

      This proxy statement provides you with detailed information about the
proposed merger and provides the complete merger agreement as Appendix A. A copy
of the opinion of Hovde, which sets forth the assumptions made, matters
considered and limitations on the review undertaken by Hovde, is provided as
Appendix B. Please read the enclosed materials carefully.

      Your board of directors joins with me in inviting you to attend the
meeting. REGARDLESS OF THE NUMBER OF SHARES YOU OWN OR WHETHER YOU PLAN TO
ATTEND THE MEETING IN PERSON, WE URGE YOU TO COMPLETE, DATE, SIGN AND RETURN THE
ENCLOSED PROXY CARD AS SOON AS POSSIBLE SO THAT YOUR SHARES WILL BE REPRESENTED
AND VOTED AT THE MEETING. A prepaid return envelope is provided for this
purpose. You may revoke your proxy at any time before it is exercised and it
will not be used if you attend the meeting and choose to vote in person. If the
merger is consummated, you will receive instructions for




surrendering your common stock certificates and a letter of transmittal to be
used for this purpose. You should not submit your stock certificates until then.

Sincerely,




/s/ Paul L. Thomas

held at the primary location of Community Bank of Excelsior Springs, a Savings
Bank, located at 1001 North Jesse James Road, Excelsior Springs, Missouri, at

      1.  To consider and vote upon a proposal to approve and adopt the
          Agreement and Plan of Merger dated as of September 5, 2002, by and

          ("Acquisition Sub") and CBES, pursuant to which Acquisition Sub will
          merge with and into CBES and each of the outstanding shares of CBES
          common stock (other than shares held by CBES as treasury stock and
          shares held by dissenting stockholders who have properly demanded and
          perfected their appraisal rights) will be converted into the right to
          receive $17.50 in cash, subject to adjustment in certain
          circumstances, as more fully described in the accompanying proxy
          statement.

          The above matter is more fully described in the accompanying proxy
          statement, to which a copy of the Agreement and Plan of Merger is
          attached as Appendix A.

      2.  To transact such other business as properly may come before the
          meeting and any adjournment thereof.


      You are entitled to notice of and to vote at the meeting if you owned CBES
common stock at the close of business on the October 15, 2002 record date.


      Stockholders of CBES who dissent from the proposed merger and otherwise
comply with the requirements of the General Corporation Law of the State of
Delaware have the right to seek appraisal of their shares. See "Dissenters'
Appraisal Rights" in the proxy statement for a description of the procedures
required to be followed to seek appraisal.

                                    By Order of the Board of Directors



                                    /s/ Paul L. Thomas

                 QUESTIONS AND ANSWERS ABOUT THE PROPOSED MERGER

Q:    WHY IS CBES PROPOSING TO MERGE?

A:    Your board of directors believes that the proposed merger would allow
      stockholders of CBES to realize greater value for their shares of
      common stock than they could obtain if CBES followed its existing
      business plan, or pursued other alternative strategies to maximize
      stockholder value.  CBES and NASB share a commitment to community
      banking, which emphasizes responsiveness to local markets and the
      delivery of personalized services.  We believe that the proposed merger
      will provide customers and the local communities served by CBES and
      NASB access to a wider variety of quality products and services while
      continuing to receive the high level of personal service they have come
      to expect.


Q:    WHEN AND WHERE IS THE SPECIAL MEETING?

A:    The special meeting is to be held at the primary location of Community
      Bank of Excelsior Springs, a Savings Bank, located at 1001 North Jesse
      James Road, Excelsior Springs, Missouri on December 12, 2002, commencing
      at 9:00 a.m., local time.


Q:    WHAT WILL I RECEIVE FOR MY SHARES OF CBES COMMON STOCK?


A:    You will receive $17.50 in cash for each share of CBES common stock that
      you own at the time of the merger, which amount could be subject to
      adjustment as explained below. See the discussion under the caption
      "Payment For CBES Shares" beginning at page 24 for more information.


Q:    IS THE AMOUNT OF CASH TO BE RECEIVED FOR EACH SHARE OF COMMON STOCK
      FAIR?


A:    Hovde Financial LLC, the Financial Advisor to CBES in the merger, has
      delivered a written opinion to CBES's board of directors that the merger
      consideration to be paid to CBES stockholders is fair from a financial
      point of view. See the discussion under the caption "Opinion of CBES's
      Financial Advisor" beginning at page 19 for more information.


Q:    CAN THE AMOUNT OF CASH THAT CBES STOCKHOLDERS RECEIVE IN THE MERGER
      CHANGE ?


A:    The per share cash consideration to be received by CBES stockholders in
      the merger will be subject to adjustment if the adjusted stockholders'
      equity of CBES as of the close of business on the last business day
      immediately prior to the effective time of the merger is less than
      $13,900,000, but equal to or greater than $13,500,000, in which event
      the per share cash consideration will be reduced to $17.05 per share.
      Moreover, if the adjusted stockholders' equity of CBES is less than
      $13,500,000, NASB may elect to terminate the merger agreement or to
      consummate the merger at $17.05 per share.  See the discussion under
      the caption "Payment for CBES Shares" beginning at page 24 for more
      information.


Q:    WHAT ARE THE TAX CONSEQUENCES OF THE MERGER TO CBES STOCKHOLDERS?


A:    For United States federal income tax purposes, and perhaps for state and
      local tax purposes, your exchange of shares of common stock for cash
      generally will cause you to recognize a gain or loss measured by the
      difference between the cash you receive in the merger and your tax basis
      in the shares of common stock. See the discussion under the caption
      "Federal Income Tax Consequences" beginning at page 32 for more
      information.


      The tax consequences of the merger to you will depend on your own
      situation. You should consult with your tax advisors for a full
      understanding of the tax consequences of the merger to you.

1


Q:    WHAT CAN I DO IF I AM NOT SATISFIED WITH THE PAYMENT I AM TO RECEIVE
      FOR MY SHARES?


A:    Under Delaware law, if you are not satisfied with the amount you are to
      receive in the merger, you are legally entitled to have the value of
      your shares judicially determined and to receive payment based on that
      valuation.  To exercise your dissenters' appraisal rights, you must
      deliver a written objection to the merger to CBES at or before the
      meeting and must not vote in favor of the merger.  Objections to the
      merger should be addressed to CBES at 1001 North Jesse James Road,
      Excelsior Springs, Missouri 64024, Attention: Corporate Secretary.  If
      you do not follow exactly the procedures specified under Delaware law,
      you will lose your dissenters' appraisal rights.  A copy of the
      dissenters' appraisal rights provisions of Delaware law is provided as
      Appendix C to this proxy statement.  See the discussion under the
      caption "Dissenters' Appraisal Rights" beginning at page 36 for more
      information.


Q.    WILL CBES BE ABLE TO PAY DIVIDENDS BEFORE THE COMPLETION OF THE MERGER?

A.    No.  Under the merger agreement, CBES is not permitted to pay normal
      quarterly cash dividends during the period from the September 5, 2002
      date of the merger agreement until the date that the merger becomes
      effective.

Q.    HOW WILL MANAGEMENT BENEFIT FROM THE MERGER?


A.    Officers and directors of CBES who have stock options and restricted
      stock awards under CBES's benefit plans will receive payments for their
      awards based upon the merger price per share.  Any unvested stock
      options automatically will be deemed to be vested and will be converted
      at the effective time of the merger into the right to receive cash
      equal to the difference between the merger price per share and the
      exercise price per share of the options.  Under Community Bank's
      severance plan and agreements, all full-time salaried and full-time
      hourly employees of Community Bank will be entitled to the payment of
      severance benefits if such persons are terminated without cause within
      a specified period before and after the effective time of the merger or
      such persons voluntarily leave during that period due to certain
      changes in their employment conditions or compensation.  In addition,
      Paul L. Thomas, the Chairman of the Board and CEO of CBES, and certain
      key officers, have entered into agreements with Community Bank wherein
      they shall receive a bonus if they choose to continue their employment
      with Community Bank through the effective time of the merger.
      Community Bank has entered into salary continuation agreements with
      Dennis D. Hartman, the President of Community Bank, Margaret E.
      Teegarden, the Savings Department Manager of Community Bank and James
      V. Alderson, Loan Officer of Community Bank, that entitle each
      individual to a lump sum payment equal to the amount of benefits
      accrued if any such person is terminated or resigns within 12 months of
      the effective time of a change in control.  Community Bank has also
      entered into change of control agreements with Mr. Hartman and Ms.
      Teegarden which provide for a lump sum payment if, within 12 months of
      the effective time of a change in control, either is terminated without
      cause or resigns due to a material change in his or her duties,
      compensation or certain other aspects of his or her employment
      arrangement.   Finally, NASB has agreed to indemnify the officers and
      directors of CBES and Community Bank for a period of six years from
      liability and expenses arising out of matters existing or occurring at
      or prior to the consummation of the merger and to pay up to $50,000 of
      the premium required to extend the director and officer insurance
      coverage beyond the closing date of the merger.  See the discussion
      under the caption "Interests of Certain Persons in the Merger"
      beginning at page 33 for more information.


Q.    WHAT DO I NEED TO DO NOW?


A.    After you have carefully read this proxy statement, indicate on your proxy
      card how you want your shares of common stock to be voted. Then sign, date
      and mail your proxy card in the

2


      enclosed prepaid return envelope as soon as possible. This will enable
      your shares to be represented and voted at the special meeting.


Q.    WHAT IF I DON'T VOTE OR ABSTAIN FROM VOTING?


A.    If you do not return your proxy card or vote in person at the special
      meeting, your failure to vote or abstention from voting will have the
      effect of a vote against the merger. The merger agreement must be approved
      by a majority of the outstanding shares of common stock entitled to vote
      at the meeting. See the discussion under the caption "Voting Rights -
      Required Vote" on page 12 for more information.


Q.    IF MY SHARES ARE HELD IN STREET NAME BY MY BROKER, WILL MY BROKER
      AUTOMATICALLY VOTE MY SHARES FOR ME?

A.    No.  Your broker will not be able to vote your shares of common stock
      without instructions from you.  You should instruct your broker how you
      wish to vote your shares, following the directions your broker provides.

Q     WHAT IF I FAIL TO INSTRUCT MY BROKER?

A.    If you fail to instruct your broker to vote your shares held in street
      name, your broker's inability to vote your shares will be the equivalent
      of voting against the merger.


Q.    AFTER SENDING IN MY PROXY, CAN I ATTEND THE SPECIAL MEETING AND VOTE MY
      SHARES IN PERSON?

A.    Yes.  You are invited to attend the special meeting.  If you are a
      stockholder of record, you are entitled to revoke your proxy and vote
      in person at the meeting if you wish to do so.  If a broker holds your
      shares in street name, then you are not the stockholder of record and
      you must ask your broker how you can vote in person at the meeting.


Q.    CAN I CHANGE MY VOTE AFTER SENDING IN MY PROXY?

A.    Yes.  If you have not voted through your broker, there are three ways
      you can change your vote after you have sent in your proxy card.


      *  First, you may send a written notice to the Corporate Secretary of CBES
         before your common stock has been voted at the special meeting stating
         that you are revoking your proxy.

      *  Second, you may complete a new proxy card and provide it to the
         Corporate Secretary of CBES before your common stock has been voted at
         the meeting. Any earlier proxy will be revoked automatically.


      *  Third, you may attend the meeting, revoke your proxy at the meeting and
         vote in person. Simply attending the meeting without voting will not
         revoke your proxy. If you have instructed your broker to vote your
         shares, you must follow the directions of your broker to change your
         vote.

Q.    SHOULD I SEND IN MY SHARE CERTIFICATES NOW?

A.    No.  You should not send in your common stock certificates at this
      time.  Instructions for exchanging common stock certificates will be
      sent to you after the merger has been completed.

Q:    WHEN DO YOU EXPECT THE MERGER TO BE COMPLETED?


A:    CBES hopes to complete the merger in the fourth quarter of 2002. The
      merger cannot occur unless CBES stockholders approve the merger by a
      majority of the outstanding shares of common

3


      stock and all federal regulatory approvals are received. See the
      discussion under the caption "Conditions to the Merger" beginning at page
      26 for more information.


Q:    WHO CAN HELP ANSWER MY QUESTIONS?

A:    If you have more questions about the merger, you should contact:


            Paul L. Thomas, CEO, or Dennis D. Hartman, President
            Telephone: (816) 630-6711

THE MERGER


Overview of the Transaction (page    We propose a merger in which
18)                                  Acquisition Sub will merge with
                                     and into CBES. As a result of this
                                     transaction, Acquisition Sub will cease to
                                     exist and CBES will become a wholly-owned
                                     subsidiary of NASB.

What You Will Receive for Your       As a CBES stockholder at the
Shares of Common Stock (page 24)     effective time of the merger, each
                                     of your shares of CBES common stock will
                                     automatically be converted into the right
                                     to receive $17.50 in cash, subject to
                                     adjustment under certain circumstances.
                                     After the merger is effective, you will
                                     have to surrender your CBES stock
                                     certificates to receive this cash payment.
                                     NASB, or its exchange agent, will send you
                                     written instructions for surrendering your
                                     certificates after the merger. DO NOT SEND
                                     YOUR STOCK CERTIFICATES AT THIS TIME.


                                     CBES common stock is quoted on the NASDAQ
                                     National Market SM under the symbol "CBES".
                                     On September 5, 2002, which is the day the
                                     last trade occurred before we announced the
                                     merger, CBES common stock closed at $13.50
                                     per share.


Taxable Transaction for CBES         For federal income tax, and
Stockholders (page 32)               possibly state and local tax,
                                     purposes, your exchange of shares of common
                                     stock for cash generally will cause you to
                                     recognize a gain or loss measured by the
                                     difference between the cash you receive in
                                     the merger and your tax basis in the shares
                                     of common stock. The tax consequences of
                                     the merger to you will depend on your own
                                     situation. You should consult with your tax
                                     advisors for a full understanding of the
                                     tax consequences of the merger to you.

                                     approving the merger agreement, please see

Appraisal in the Merger (page 36)    rights of appraisal under Delaware
                                     law. This means that if you are not
                                     satisfied with the amount you are to
                                     receive in the merger, you are entitled to

                                     determined by the Delaware Court of

                                     your dissenter's rights, you must carefully
                                     follow the procedures described at pages 36
                                     through 39 of this proxy statement and

(page 26)                            number of conditions being met. In addition
                                     to the parties complying with the merger
                                     agreement, these conditions include:


                                     o  approval of the merger
                                        agreement by CBES stockholders;

                                     o  approval of the merger by
                                        regulatory authorities;

8


                                     o  the absence of any order, decree,
                                        ruling, injunction or legal restraint
                                        blocking the merger or of government
                                        proceedings trying to block the merger;
                                        and

                                     o  the absence of any law or
                                        regulation that makes the
                                        merger illegal.

                                     Where the law permits, CBES or NASB could
                                     decide to complete the merger even though
                                     one or more of these conditions has not
                                     been met. We cannot be certain when or if
                                     the conditions to the merger will be
                                     satisfied or waived, or that the merger
                                     will be completed.


Terminating the Merger Agreement     We and NASB can agree at any time
(page 31)                            not to complete the merger, even
                                     if the stockholders of CBES have approved
                                     it. Also, CBES or NASB can decide, without
                                     the consent of the other, to terminate the
                                     merger agreement if:


                                     o  the stockholders of CBES do not
                                        approve the merger agreement;

                                     o  a required regulatory approval
                                        is denied or a governmental
                                        authority blocks the merger;

                                     o  we do not complete the merger
                                        by January 31, 2003; or

                                     o  the other party makes a
                                        misrepresentation, breaches a warranty
                                        or fails to fulfill a covenant that
                                        would have a material adverse effect on
                                        the party seeking to terminate the
                                        merger agreement.

                                     CBES may terminate the merger agreement if
                                     our board of directors determines that it
                                     must accept a superior offer from a third
                                     party in the exercise of its fiduciary
                                     duties.


                                     NASB may elect to terminate the merger
                                     agreement if the adjusted stockholders'
                                     equity of CBES at the close of business on
                                     the last business day prior to the
                                     effective time of the merger is less than
                                     $13,500,000, or to consummate the merger at
                                     $17.05 per share. In addition, NASB may
                                     terminate the merger agreement if a Phase I
                                     and Phase II environmental assessment of
                                     the property on which Community Bank's
                                     primary banking facility is located in
                                     Excelsior Springs, Missouri results in a
                                     determination that environmental clean-up
                                     costs on such property would exceed
                                     $500,000.

We May Amend the Terms of the        We can agree with NASB to amend

                                     agreement, no amendment may be made that
                                     would violate applicable law or would
                                     reduce or change the consideration to be
                                     received by the stockholders in the merger.

                                  INTRODUCTION


      This proxy statement is furnished to the stockholders of CBES Bancorp,
Inc., a Delaware corporation ("CBES"), in connection with the solicitation of
proxies by the board of directors of CBES (the "board") for use at the special
meeting of stockholders of CBES to be held on December 12, 2002, commencing at
9:00 a.m., local time, at the primary location of Community Bank of Excelsior
Springs, a Savings Bank, located at 1001 North Jesse James Road, Excelsior
Springs, Missouri (the "special meeting"). This proxy statement, the notice and
the accompanying form of proxy were first mailed to the stockholders of CBES on
October 28, 2002.


MATTERS TO BE CONSIDERED AT THE SPECIAL MEETING

      At the special meeting, stockholders will be asked to consider and vote
upon the approval and adoption of an agreement and plan of merger dated as of
September 5, 2002, by and among NASB Financial, Inc. ("NASB"), NASB Acquisition
Subsidiary, Inc. ("Acquisition Sub"), and CBES (the "merger agreement"). A copy
of the merger agreement is attached hereto as Appendix A.

      The merger agreement provides for the merger of Acquisition Sub, a newly
formed wholly-owned subsidiary of NASB, with and into CBES (the "merger"), and
for CBES to continue as the surviving corporation in the merger under the same
name. As a result of the merger, each outstanding share of CBES common stock,
par value $.01 per share ("common stock") (other than shares held by CBES as
treasury stock and shares held by dissenting stockholders who perfect their
statutory appraisal rights), will be converted into the right to receive $17.50
in cash per share, subject to adjustment in certain circumstances.

      The board knows of no other matters which will be presented for
consideration at the special meeting. If any other matters are properly
presented at the meeting, the accompanying proxies confer upon the persons named
in the proxies discretionary authority to vote upon such matters, to the extent
permitted under the applicable rules of the Securities and Exchange Commission.
This would include a motion to adjourn or postpone the special meeting in order
to solicit additional proxies. However, no proxy voted against the proposal to
approve the merger agreement will be voted in favor of an adjournment or
postponement to solicit additional votes in favor of the merger agreement.

VOTING RIGHTS

General


      Stockholders of record of common stock as of the close of business on the
record date, October 15, 2002, are entitled to notice of and to vote at the
special meeting. At the close of business on the record date, there were issued
and outstanding 875,805 shares of common stock. Each share of common stock has
one vote.

Voting by Proxy

      When a proxy in the accompanying form is properly executed and returned,
the shares represented by the proxy will be voted at the special meeting in the
manner specified by the stockholder. If no instructions are specified, authority
will be granted to vote such shares FOR the approval and adoption of the merger
agreement. Unless otherwise indicated on the proxy, discretionary authority will
also be granted to the persons named in the proxy to vote the shares represented
by the proxy with respect to procedural matters and other matters that may
properly come before the meeting.


      If you are a beneficial owner of shares held by a broker, bank or other
nominee (commonly referred to as being held in "street name"), you will receive
instructions from your broker or bank that you must follow in order to have your
shares voted by your nominee. Your broker or bank may allow you to deliver your
voting instructions via the telephone or the Internet. If you hold your shares
in street name and

11


want to vote in person at the special meeting, you will have to get a proxy from
the broker, bank or other nominee holding your shares, which proxy grants you
the right to vote such shares.


Participants in the Employee Stock Ownership Plan


      If you participate in the Community Bank Employee Stock Ownership Plan,
the enclosed proxy card represents a voting instruction to the trustee of the
plan as to the number of shares in your plan account. Each participant in the
plan may direct the trustee as to the manner in which shares of common stock
allocated to the participant's plan account are to be voted. Unallocated shares
of common stock held by the plan and allocated shares for which no voting
instructions are received will be voted by the trustee in the same proportion as
shares for which the trustee has received voting instructions, subject to the
trustee's exercise of his fiduciary obligations.

Quorum; Abstention/Broker Non-Votes

      The presence in person or by proxy of the holders of one-third of the
outstanding shares of common stock will constitute a quorum for the transaction
of business at the special meeting. If a quorum is not present at the special
meeting, the meeting may be adjourned until such time as a quorum is obtained.
If you attend the meeting in person or by proxy, your shares will be counted for
purposes of determining whether there is a quorum, even if you abstain from
voting. Broker non-votes will also be counted for purposes of determining the
existence of a quorum. A broker non-vote occurs when a broker, bank or other
nominee holding shares for a beneficial owner presents a valid proxy, but does
not vote on a particular proposal because the nominee has not received voting
instructions from the beneficial owner and does not have discretionary voting
power with respect to the matter being voted upon.

Required Vote

      The approval and adoption of the merger agreement will require the
affirmative vote of the holders of at least a majority of the outstanding shares
of common stock entitled to vote thereon. Thus, failure to return a properly
executed proxy card or to vote in person will have the same effect as a vote
against the merger agreement. Abstentions from voting and broker non-votes
(failure to give your broker voting instructions if your shares are held in
street name) will also have the same effect as a vote against the merger
agreement.

      The stockholders present at the special meeting in person or by proxy may,
by a majority vote, vote to adjourn the meeting in the absence of a quorum, or
to adjourn the meeting even if a quorum is present. If a quorum is not present,
or if less than a majority of the outstanding shares are present and voting in
favor of the approval and adoption of the merger agreement, it is expected that
the meeting with be adjourned to allow additional time to solicit proxies.

Revocation of Proxies

      A stockholder may revoke his or her proxy at any time before it is voted
by giving the Secretary of CBES written notice of revocation bearing a later
date than the proxy, by submitting a later-dated proxy, or by revoking the proxy
and voting in person at the special meeting. Attendance at the special meeting
will not in and of itself constitute a revocation of a proxy. Any written notice
revoking a proxy should be sent to the Corporate Secretary of CBES at 1001 North
Jesse James Road, Excelsior Springs, Missouri 64024.

Solicitation of Proxies

      The costs of soliciting proxies will be borne by CBES. Proxies may be
solicited by certain of CBES's directors, officers and regular employees,
without additional compensation, in person or by telephone, email or facsimile.
CBES will request brokers and nominees who hold shares of common stock in their
names to furnish proxy materials to beneficial owners of common stock and will
reimburse such

12


brokers and nominees for their reasonable expenses incurred in forwarding
solicitation materials to such beneficial owners.

                            BACKGROUND OF THE MERGER


      CBES is the holding company for Community Bank of Excelsior Springs, a
Savings Bank ("Community Bank"). CBES was organized by Community Bank for the
purpose of acquiring all of the capital stock of Community Bank in connection
with the conversion of Community Bank from mutual to stock form, which was
completed on September 27, 1996. The only significant assets of CBES are the
capital stock of Community Bank and CBES's loan to the Community Bank Employee
Stock Ownership Plan. Community Bank is a community-oriented financial
institution offering selected financial services, through its main office in
Excelsior Springs, Missouri, and its branch office in Liberty, Missouri, to
customers located in Clay and Ray Counties and to a lesser extent in surrounding
counties in Missouri. Community Bank attracts deposits from the general public
and has historically used such deposits primarily to originate one-to-four
family residential mortgage loans, construction and land loans for single-family
residential properties and consumer loans consisting principally of loans
secured by automobiles. Community Bank has also been an active participant in
the secondary market, originating residential mortgage loans for sale. At June
30, 2002, CBES had consolidated total assets of $112.9 million, deposits of
$87.8 million, and total stockholders' equity of $14.2 million.


      Since the inception of CBES, the board has monitored the rapid pace of
consolidation in the financial services industry. An indication of interest from
NASB led the board to consider whether it would be in the best interests of CBES
and its stockholders to explore CBES's strategic alternatives,

15


including the possibility of a business combination with another financial
institution. On August 9, 2001, as part of its regular review of CBES's
strategic alternatives, the board charged management with the initial
responsibility of seeking the assistance of a financial advisor to CBES. At four
separate meetings of the board held during September and October 2001, the board
heard presentations from four financial advisory firms. On October 23, 2001, the
board selected Hovde Financial LLC ("Hovde") to provide CBES consulting and
strategic planning advice.


      On January 3, 2002, the board met with representatives of Hovde to review
and evaluate the strategic alternatives available to CBES. The board, after
careful review of the alternatives, determined that CBES's efforts should be
initially focused on either a business combination with an equal size or larger
financial institution or an acquisition of another financial institution, and
authorized Hovde to pursue the possibility of a strategic business combination
for CBES. As part of this process, the board authorized Hovde to prepare a list
of appropriate financial institutions to be contacted to obtain expressions of
interest in a possible business combination with CBES.


      On March 12, 2002, the board reviewed forms of a confidentiality and
standstill agreement and confidential descriptive memorandum of CBES to be
provided to prospective strategic merger partners. The board also reviewed a
list of financial institutions to be contacted. On March 12, 2002, the board
approved the confidentiality and standstill agreement, the confidential
descriptive memorandum and the list of institutions to be contacted. The board
further authorized Hovde to proceed to contact and negotiate with potential
strategic merger partners on behalf of CBES.


      Hovde approached 49 financial institutions that it and CBES considered to
be potential merger partners. Several of those companies, including NASB,
expressed an interest in a possible business combination with CBES. After
further discussions with Hovde and the providing of additional information
regarding CBES, five of the companies stated a price range at which they would
be interested in acquiring CBES, subject to their satisfactory completion of due
diligence reviews of CBES's operations. The board voted to invite four of the
companies to perform due diligence reviews of CBES. Between June 17 and June 20,
2002, the four financial institutions completed such due diligence reviews of
CBES. Two of the parties withdrew after completing their reviews. On June 25,
2002, Hovde submitted final proposal instructions to the two parties that had
indicated their desire to make final proposals. Hovde's representatives held
discussions with each of the interested institutions for the purpose of refining
their offers and ascertaining whether a transaction with CBES would be possible.
Evidence of the financial ability of one of the parties to complete a
transaction with CBES was also requested by Hovde.

      At a meeting of the board on July 12, 2002, Hovde reviewed with the board
the process that had been conducted to identify and contact potential merger
partners and the results of the discussions with the interested parties. Hovde
reviewed with the board in detail the two offers which it had received and the
financial information which had been obtained from the bidders. The board
concluded that the offer of NASB was more attractive, as the other party had not
provided satisfactory evidence of financing and NASB appeared to be in a
financial position to complete the transaction. NASB is headquartered in
Grandview, Missouri, and is the parent corporation of North American Savings
Bank, F.S.B., a federally chartered savings and loan association ("North
American"). At June 30, 2002, NASB had consolidated assets of $932 million, net
loans receivable of $850 million and stockholders' equity of $104 million.


      At the July 12 board meeting, Stinson Morrison Hecker LLP, as legal
counsel for CBES, reviewed with the board its fiduciary duties to stockholders.
Hovde also presented and discussed with the board its financial analyses of the
purchase price offered by NASB and stated it would be prepared to deliver, upon
the execution of a definitive merger agreement, a written opinion to the board
that the merger consideration offered by NASB was fair, from a financial point
of view, to the stockholders of CBES. After considering the terms of the
proposal and the presentation by Hovde, the board determined that pursuing a
transaction with NASB on the terms proposed would be in the best interests of
CBES and its stockholders. The board then authorized its representatives to
enter into discussions with NASB for the purpose of negotiating a definitive
merger agreement.

      Following the July 12 board meeting, CBES's legal counsel and legal
counsel for NASB entered into discussions to negotiate the terms of the merger
agreement. Over the next few weeks, representatives

16


of CBES also conducted a limited due diligence review of NASB and North
American. During this period, the parties worked to further refine the pricing
of the transaction. The progress of these negotiations was periodically reported
to the members of the CBES board by a negotiating committee.


      A draft of the merger agreement that was substantially in the form of the
final agreement was provided to the board prior to a meeting on September 3,
2002. At the September 3 meeting, the CBES negotiating committee reviewed in
detail with the board the contents of the proposed merger agreement.
Representatives of Hovde presented by conference telephone their detailed
financial analyses of the proposed transaction. Hovde reported that in its
opinion the merger consideration was fair, from a financial point of view, to
CBES stockholders and delivered to the board a letter to this effect, dated
September 3, 2002.

      Upon conclusion of the foregoing review and discussions, a vote was taken
and the board, by a vote of five directors in favor and two directors opposed,
concluding that the merger agreement should be approved and authorizing Paul L.
Thomas to execute the merger agreement and related documents on behalf of CBES.
Richard N. Cox and C.E. Lamb voted against the approval of the merger agreement.

                              THE MERGER AGREEMENT

GENERAL

      All references to and summaries of the merger agreement contained herein
are qualified in their entirety by reference to the text of the merger
agreement, which is attached hereto as Appendix A.

      The merger agreement provides that, subject to the approval thereof by the
stockholders of CBES and the satisfaction of certain other conditions,
Acquisition Sub, a wholly-owned subsidiary of NASB, will be merged with and into
CBES, with CBES being the surviving corporation and thereby becoming
wholly-owned by NASB. Acquisition Sub was formed by NASB solely for the purposes
of carrying out the merger and has no business or significant assets. At the
effective time of the merger, the separate existence of Acquisition Sub will
cease.


      At the effective time of the merger, each outstanding share of common
stock of CBES (other than shares held by CBES as treasury stock and shares held
by dissenting stockholders who perfect their statutory appraisal rights) will be
converted into the right to receive $17.50 in cash per share, subject to
adjustment in certain circumstances. See "Payment For CBES Shares" below.
Notwithstanding the foregoing, appraisal rights will be available for shares of
any dissenting stockholder who complies with the provisions of the General
Corporation Law of the State of Delaware regarding appraisal rights. See "Rights
of Dissenting Stockholders" below. Except for the foregoing rights, after the
merger present holders of common stock of CBES will possess no interest in the
stock or other rights as stockholders of CBES.


      The merger agreement provides that the officers and directors of CBES
shall resign at the effective time of the merger and that NASB shall appoint new
officers and directors of CBES. The directors and certain designated officers of
Community Bank immediately prior to the merger are also required to resign at
the effective time of the merger.

RECOMMENDATION OF THE BOARD OF DIRECTORS

      THE CBES BOARD OF DIRECTORS HAS APPROVED THE MERGER AGREEMENT AND
RECOMMENDS THAT THE CBES STOCKHOLDERS APPROVE AND ADOPT SUCH AGREEMENT.

REASONS FOR THE MERGER

      The board has determined that the merger and the merger agreement are
advisable and are fair to, and in the best interests of, CBES and its
stockholders. In reaching this determination, the board considered a number of
factors, including the following:


     o    The board's  knowledge  of CBES's and  Community  Bank's  consolidated
          business   operations,   management,   operating  results,   earnings,
          financial condition and prospects.

     o    Information  concerning  NASB's  and  North  American's   consolidated
          business   operations,   management,   operating  results,   earnings,
          financial condition and prospects, as a separate group and as combined
          with CBES.

     o    The oral and written  financial  analyses  presented by Hovde,  as the
          financial  advisor to CBES,  and the  opinion of Hovde that the merger
          consideration  is  fair,  from a  financial  point  of  view,  to CBES
          stockholders. (See "Opinion of CBES's Financial Advisor" below).

     o    The fact that the proposed merger will provide CBES  stockholders with
          the  opportunity to receive  $17.50 in cash per share,  as adjusted in
          certain  circumstances,  which represents a premium over the prices at
          which the CBES common stock has recently traded. On September 5, 2002,
          the last trading date prior to the public  announcement  that CBES and
          NASB had entered into a merger  agreement,  the closing  price of CBES
          common stock was $13.50 per share.

18


     o    The  historical  trading  prices for CBES common  stock.  (See "Market
          Price and Dividend Data for CBES Common Stock" above.)

     o    The board's assessment that Hovde had made diligent efforts to solicit
          prospective  merger partners for CBES and the board's  conclusion that
          the merger  transaction  proposed  by NASB was  superior  to the other
          transactions available to CBES and its stockholders.

     o    The results of CBES's due diligence  investigations of NASB, including
          the board's  assessment  of the  financial  ability of NASB to pay the
          merger  consideration and the likelihood of the merger with NASB being
          approved by regulatory authorities.

     o    The terms of the merger agreement, including the taxable nature of the
          cash consideration to be paid to CBES stockholders.

     o    The current  and  prospective  economic,  competitive  and  regulatory
          environment facing CBES, NASB and the financial services industry.

     o    CBES's strategic alternatives to the merger, including the alternative
          of continuing to operate CBES as an independent financial institution.


The foregoing discussion of the information and factors considered by the board
is not intended to be exhaustive. In reaching its determination to approve and
recommend the merger to stockholders, the board did not quantify or assign
relative weights to any of the foregoing factors. In addition, individual
directors gave different weights to different factors, as evidenced by the vote
of two directors against approval of the merger agreement.

OPINION OF CBES'S FINANCIAL ADVISOR

      Hovde Financial LLC has acted as financial advisor to CBES in connection
with the proposed merger. CBES selected Hovde based on its experience and
expertise in the investment-banking business.

      Hovde has delivered to the CBES board its opinion that, based upon and
subject to the various considerations set forth in its written opinion dated
September 3, 2002, the merger consideration is fair from a financial point of
view to the holders of CBES common stock as of such date. In requesting Hovde's
advice and opinion, no limitations were imposed by CBES upon Hovde with respect
to the investigations made or procedures to be followed by it in rendering its
opinion.


      THE FULL TEXT OF THE OPINION OF HOVDE, DATED SEPTEMBER 3, 2002, WHICH
DESCRIBES THE PROCEDURES FOLLOWED, ASSUMPTIONS MADE, MATTERS CONSIDERED AND
LIMITATIONS ON THE REVIEW UNDERTAKEN, IS ATTACHED HERETO AS APPENDIX B. CBES
STOCKHOLDERS SHOULD READ THIS OPINION IN ITS ENTIRETY. HOVDE'S OPINION IS
DIRECTED ONLY TO THE FAIRNESS, FROM A FINANCIAL POINT OF VIEW, OF THE MERGER
CONSIDERATION, AND DOES NOT CONSTITUTE A RECOMMENDATION TO ANY CBES STOCKHOLDER
AS TO HOW THE STOCKHOLDER SHOULD VOTE AT THE SPECIAL MEETING. THE SUMMARY OF THE
OPINION OF HOVDE SET FORTH IN THIS PROXY STATEMENT IS QUALIFIED IN ITS ENTIRETY
BY REFERENCE TO THE FULL TEXT OF THE OPINION.


      Hovde, as part of its investment banking business, is continually engaged
in the valuation of businesses and their securities in connection with mergers
and acquisitions, negotiated underwritings, competitive bidding, secondary
distributions of listed and unlisted securities, private placements and
valuations for estate, corporate and other purposes. Hovde is familiar with
CBES, having acted as its financial advisor in connection with, and having
participated in the negotiations leading to, the merger agreement. In the course
of its daily trading activities, investment funds controlled by an affiliate (as
such term is defined in Regulation 12G-2 promulgated under the Securities
Exchange Act of 1934, as amended) of Hovde and their affiliates may from time to
time effect transactions and hold securities of CBES and NASB. As of the date of
its opinion, Hovde-affiliated entities owned no shares of either company.

      Hovde will receive a fee contingent upon the completion of the merger for
services rendered in connection with advising CBES regarding the merger,
including the fairness opinion and financial advisory services provided to CBES.
As of the date of this proxy statement, such fee would have been approximately
$200,000 and Hovde has received $50,000 of such fee to date.

19


      The following is a summary of the analyses performed by Hovde in
connection with its fairness opinion. Certain of these analyses were presented
to the CBES board by Hovde on September 3, 2002. The summary set forth below
does not purport to be a complete description of either the analyses performed
by Hovde in rendering its opinion or the presentation made by Hovde to the
board, but it does summarize all of the material analyses performed and
presented by Hovde.

      The preparation of a fairness opinion involves various determinations as
to the most appropriate and relevant methods of financial analyses and the
application of those methods to the particular circumstances. In arriving at its
opinion, Hovde did not attribute any particular weight to any analysis and
factor considered by it, but rather made qualitative judgments as to the
significance and relevance of each analysis and factor. Hovde may have given
various analyses more or less weight than other analyses. Accordingly, Hovde
believes that its analyses and the following summary must be considered as a
whole and that selecting portions of its analyses, without considering all
factors and analyses, could create an incomplete view of the process underlying
the analyses set forth in its report to the CBES board and its fairness opinion.

      In performing its analyses, Hovde made numerous assumptions with respect
to industry performance, general business and economic conditions and other
matters, many of which are beyond the control of CBES and NASB. The analyses
performed by Hovde are not necessarily indicative of actual value or actual
future results, which may be significantly more or less favorable than suggested
by such analyses. Such analyses were prepared solely as part of Hovde's analysis
of the fairness of the merger consideration, from a financial point of view, to
the CBES stockholders. The analyses do not purport to be an appraisal or to
reflect the prices at which a company might actually be sold or the prices at
which any securities may trade at the present time or at any time in the future.
Hovde's opinion does not address the relative merits of the merger as compared
to any other business combination in which CBES might engage. In addition, as
described above, Hovde's opinion to the board was one of many factors taken into
consideration by the board in making its determination to approve the merger
agreement.

      During the course of Hovde's engagement and for the purposes of the
opinion set forth herein, Hovde:

     o     reviewed the merger agreement;

     o     reviewed certain historical publicly available business and financial
           information concerning NASB and CBES;

     o     reviewed certain internal financial statements  and  other  financial
           and operating data concerning NASB and CBES;

     o     analyzed  certain financial projections prepared by the management of
           CBES;

     o     reviewed historical market prices and trading volumes for CBES common
           stock;

     o     reviewed  the terms of recent merger and acquisition transactions, to
           the  extent  publicly  available, involving thrift and thrift holding
           companies that Hovde considered relevant;

     o     analyzed the pro forma impact of the merger on the combined company's
           earnings per share, consolidated capitalization and financial ratios;
           and

     o     performed  such other analyses and considered  such other  factors as
           Hovde deemed appropriate.

      In rendering its opinion, Hovde assumed, without independent verification,
the accuracy and completeness of the financial and other information and
representations contained in the materials provided to it by NASB and CBES and
in the discussions with NASB's and CBES's management. In that regard, Hovde
assumed that the financial forecasts, including without limitation the
projections regarding under-performing and non-performing assets and net
charge-offs, have been reasonably prepared on a basis reflecting the best
currently available information and judgments and estimates of NASB and CBES,
and that such forecasts will be realized in the amounts and at the times
contemplated thereby. Hovde is not an expert in the evaluation of loan and lease
portfolios for purposes of assessing the adequacy of the allowances for losses
with respect thereto and assumed that such allowances for NASB and CBES are in
the aggregate adequate to cover such losses. Hovde was not retained to and did
not conduct a physical

20


inspection of any of the  properties or facilities of NASB or CBES. In addition,
it did not review individual credit files and did not make an independent
evaluation or appraisal of the assets and liabilities of NASB, and CBES and was
not furnished with any such evaluation or appraisal.

      Transaction Multiple Analysis. Hovde compared merger consideration to the
book value of CBES common stock, tangible book value, adjusted core 6.5%
capital, 2003 and 2004 estimated GAAP earnings per share (EPS), assets,
deposits, and tangible book value to core deposits premium. Assuming merger
consideration per share of $17.50, Hovde observed that the implied transaction
multiples to CBES were as follows:

Merger consideration to book value                      108.8%
Merger consideration to tangible book value             108.8%
Merger consideration to adjusted 6.5% core capital      115.7%
Merger consideration to 2003 FY estimated GAAP EPS       65.7x
Merger consideration to 2004 FY estimated GAAP EPS       38.0x
Merger consideration to assets                           13.7%
Merger consideration to deposits                         17.6%
Premium over tangible book value to core deposits         1.6%


      Premium to Market Analysis Based on CBES Historical Trading Values. Hovde
reviewed the merger consideration premium to CBES common stock prices during
different periods ending August 14, 2002 (the last day actual trades took place
in CBES common stock prior to September 3, 2002) using the 5-day, 10-day,
20-day, 30-day, 45-day, 60-day and 90-day average closing price of CBES common
stock on days where trades were executed. Hovde observed that the merger
consideration premium to CBES common stock average closing prices over these
periods were as follows:

                                 CBES         Merger Consideration
                                Average        Premium to Average
                             Closing Price       Closing Price
                             -------------    --------------------


Last trading day                $13.75               27.27%
Last 5 Trading Days             $13.77               27.09%
Last 10 Trading Days            $13.81               26.70%

Last 90 Trading Days            $13.43               30.33%

      Stock Trading History Analysis. Hovde reviewed the history of the reported
trading prices and volume of CBES common stock and the relationship between the
movements in the prices of CBES common stock to movements in certain stock
indices, including the Standard & Poor 500 Index, the Russell 2000 Financial

the one year period ended September 3, 2002, CBES common stock underperformed
the Russell 2000 Financial Services Index and the NASDAQ Bank and Thrift Index,
and outperformed the Standard & Poor 500 Index, as reflected below:

      Analysis of Selected Mergers. Hovde reviewed comparable mergers involving
thrifts and thrift holding companies headquartered in Missouri announced since
January 1, 1999, in which the seller's assets were between $100 million and $300
million. This Missouri merger group consisted of the following four
transactions:

      Hovde also reviewed comparable mergers involving thrifts and thrift
holding companies headquartered in the Midwest announced since January 1, 1998,
in which the seller's assets were between $50 million and $500 million and
seller's non-performing assets-to-assets were in excess of 50 basis points. This
Midwest Non-Performer merger group consisted of the following seven
transactions:

      Hovde calculated the medians, averages, high and lows for the following
relevant transaction ratios in the Missouri merger group and the Midwest
Non-Performer merger group: the multiple of the offer value to the acquired
company's earnings per share for the 12 months preceding the announcement date
of the transaction; the multiple of the offer value to the acquired company's
book value per share and tangible book value per share; and the tangible book
value premium to core deposits, each as of the announcement date of


22


the transaction. Hovde compared these multiples with the corresponding multiples
for the merger, based on merger consideration per share of $17.50. The results
of this analysis are as follows:

      Hovde noted that because CBES had a negative earnings stream for the 12
months ended June 30, 2002, the multiple of the offer value to CBES's earnings
per share for the 12 months preceding June 30, 2002, would be not be meaningful.
Of the four transactions in the Missouri merger group and the seven transactions
in the Midwest Non-Performer merger group, only Cumberland Mountain Bancshares
in Kentucky had a negative earnings stream for the 12 months preceding
announcement of its merger and therefore was similarly not meaningful.

      Discounted Cash Flow Analysis. Hovde estimated the discounted present
value of the CBES common stock by using estimated 2003-2007 cash earnings of
$234.5 thousand, $405.3 thousand, $552.8 thousand, $718.3 thousand and $862.6
thousand, respectively, and 2003-2005 dividends per share of $0.32, 2006
dividends per share of $0.36 and 2007 dividends per share of $0.40. In arriving
at the terminal value of CBES's estimated earnings stream at the end of 2007,
Hovde assumed a terminal value multiple at a range of 12.5, 15.0, 17.5, 20.0 and
22.5 times earnings. The terminal value was then discounted, along with yearly
cash flows for 2003 through 2007, using a range of discount rates of 10.0%,
11.0%, 12.0%, 13.0% and 14.0% to arrive at the present value for CBES common
stock. These rates and values were chosen to reflect different assumptions
regarding the required rates of return of holders or prospective buyers of CBES
common stock. This analysis and its underlying assumptions yielded a range of
values for CBES common stock of approximately $7.67 to $15.00 per share. Hovde
noted that the merger consideration per share of $17.50 is in excess of all
values generated in this analysis.

      Marked-to-Market Analysis. Hovde calculated a liquidation value of CBES
based on estimated value of its component assets and liabilities. For purposes
of this analysis, Hovde assumed an aggregate value equal to common stockholders'
equity of CBES at June 30, 2002, as adjusted to reflect an estimated range of
values for transaction costs, premiums paid to retire existing borrowings,
deposit premiums, marked-to-market adjustments on the loan and investment
portfolios, appraisals of fixed assets, intangibles writedowns and contingent
liabilities. This analysis imputed a per share value of $14.30, which was lower
than the merger consideration per share of $17.50.


      Based upon the foregoing analyses and other investigations and assumptions
set forth in its opinion, without giving specific weightings to any one factor
or comparison, Hovde determined that the merger consideration was fair from a
financial point of view to the CBES stockholders.

23


      No material relationship has previously existed between Hovde and CBES or
NASB, or between Hovde and the affiliates of either CBES or NASB, and no future
material relationship is presently contemplated.


WHEN THE MERGER WILL BE COMPLETED


      If the merger agreement is approved by the stockholders of CBES, the
closing of the merger will take place not more than 15 days after the
satisfaction or waiver of all of the conditions to the merger contained in the
merger agreement, unless NASB and CBES agree to another date. On the date of the
closing, a Certificate of Merger will be filed with the Secretary of State of
Delaware and Articles of Merger will be filed with the Secretary of State of
Missouri. The merger will become effective at the time stated in the Certificate
and Articles of Merger (the "effective time" of the merger).

      CBES expects to complete the merger in the fourth quarter of 2002.
However, CBES cannot guarantee when or if the required approvals will be
obtained. Furthermore, either party may terminate the merger agreement if the
merger has not been completed on or before January 31, 2003, unless failure to
complete the merger by that time is due to the breach of any representation,
warranty or covenant by the party seeking to terminate the merger agreement.


PAYMENT FOR CBES SHARES


      Unless you are a dissenting stockholder who properly demands and perfects
your appraisal rights, upon the effective time of the merger your shares of CBES
common stock will be converted into the right to receive a cash payment of
$17.50 per share. Upon the effective time of the merger, you will no longer own
any common stock or have any interest in CBES, nor will you receive any stock of
NASB as a result of the merger.

      The $17.50 per share cash payment that you are to receive in the merger is
subject to adjustment based upon the level of CBES's adjusted stockholders'
equity as of the close of business on the last day immediately prior to the
effective time of the merger. If CBES's adjusted stockholders' equity
immediately prior to the effective time is more than $13,900,000, there will be
no adjustment in the $17.50 per share cash merger consideration. If CBES's
adjusted stockholders' equity immediately prior to the effective time is less
than $13,900,000 but equal to or greater than $13,500,000, the cash merger
consideration will be reduced to $17.05 per share. If CBES's adjusted
stockholders' equity is less than $13,500,000 immediately prior to the effective
time, NASB has the right to terminate the merger agreement or to close the
merger for cash merger consideration of $17.05 per share. CBES's stockholders'
equity at June 30, 2002 was $14,172,000.

      "Adjusted stockholders' equity" for purposes of the foregoing adjustments
to the merger consideration is defined in the merger agreement to exclude (i)
all professional fees related to the merger, including but not limited to legal,
investment banking and accounting fees, (ii) all severance payments from CBES or
Community Bank to employees terminated prior to the effective time, including
but not limited to cash severance payments and reimbursements for welfare
benefits pursuant to the Community Bank Severance Plan, payments of bonuses and
welfare benefits pursuant to the terms of Employee Bonus Agreements between
Community Bank and certain of its officers, and payment of accrued paid time off
and extended leave as required by the Community Bank Employee Manual, (iii) all
fair market value accounting adjustments required by Statement of Financial
Accounting Standards No. 115 after June 30, 2002, (iv) if Community Bank's
allowance for loan and lease losses ("ALLL") exceeds the amount required by
applicable statutes and regulations, any subsequent writedowns of loans and
other real estate owned treated by Community Bank as a reduction to its ALLL
instead of as a reduction to its income or stockholders' equity, to the extent
allowed by GAAP and the Office of Thrift Supervision ("OTS"), (v) all reductions
in the value of Community Bank loans requested by NASB, and (vi) the value of
all assets, leasehold improvements and expenses relating to the closing of
Community Bank's Liberty, Missouri branch.

SURRENDER OF STOCK CERTIFICATES

      CBES STOCKHOLDERS SHOULD NOT SEND IN THEIR CERTIFICATES REPRESENTING
CBES COMMON STOCK AT THIS TIME.

      Within five business days after the effective time of the merger, NASB or
an exchange agent designated by it will mail to each stockholder a form of
transmittal letter with instructions on how to surrender certificates previously
representing shares of CBES common stock for the cash merger consideration.

      When you mail your completed letter of transmittal and your CBES stock
certificates in accordance with the accompanying instructions, you may elect
either to have the amount of cash that you are entitled to receive (i) deposited
in a specified account at a financial institution of your choice or (ii) paid by
a check mailed to you. The stock certificates which you surrender will be
cancelled. You will not be entitled to receive interest on any cash to be paid
as merger consideration.

      In the event of a transfer of ownership of shares of common stock that has
not been registered on the stock transfer records of CBES, NASB may deposit the
cash merger consideration for such shares in an account at a financial
institution of a stockholder's choice, or may issue a check for the cash merger
consideration to the stockholder who holds such shares of common stock, if the
certificate representing such shares is presented with documents that are
sufficient in the reasonable discretion of NASB or its exchange agent:

     o     to evidence and effect such transfer, and

     o     to evidence that all applicable stock transfer taxes have been paid.

      If your CBES stock certificates have been lost, stolen or destroyed, you
will have to prove that you owned these certificates, and that they were lost,
stolen or destroyed, before you will be entitled to receive payment of any
merger consideration for such certificates. NASB or the exchange agent will send
you instructions on how to provide proof of ownership. You may be required to
make an affidavit and to post a bond in an amount sufficient to protect NASB
against claims related to your lost stock certificates.

      After the effective time of the merger, there will be no further transfers
of CBES common stock. Stock certificates presented for transfer after the
effective time of the merger will be canceled and exchanged for the cash merger
consideration.

      If NASB retains an exchange agent, any cash merger consideration and the
proceeds of any investments thereon that remain unclaimed by stockholders 12
months after the effective time of the merger will be repaid by the exchange
agent to NASB. Stockholders who have not complied with the exchange procedures
prior to 12 months after the merger may only look to NASB for payment of the
cash merger consideration they are entitled to receive in exchange for their
shares of common stock and such payments will not include any interest.

      Each outstanding and unexercised option for the purchase of common stock
held by officers and employees under the CBES 1997 Stock Option and Incentive
Plan, whether or not it is vested, will be converted to a right to receive a
cash payment equal to the number of shares of common stock subject to the option
multiplied by the difference between $17.50 per share of common stock (as
adjusted) and the exercise price per share of the option. See "Stock Option
Plan" below.

REPRESENTATIONS AND WARRANTIES IN THE MERGER AGREEMENT

      Each of NASB, Acquisition Sub and CBES have made certain customary
representations and warranties to each other relating to their businesses in the
merger agreement. For information on these representations and warranties,
please refer to Article III of the merger agreement attached as Appendix A. The
representations and warranties must be true as of the date of the merger
agreement and as of the closing date of the merger. No representation or
warranty will be deemed to be untrue or incorrect and no party will be deemed to
have breached a representation or warranty unless there would likely exist a

25


material adverse effect. "Material adverse effect" is defined in the merger
agreement to mean an effect which is material and adverse to the business,
financial condition or results of operations of either party. The following,
however, are not considered in determining if there has been a material adverse
effect: (i) changes in laws, rules or regulations in GAAP or regulatory
accounting requirements or interpretations thereof; (ii) changes to economic
conditions affecting financial institutions generally; (iii) fees associated
with the merger; or (iv) changes to the merger agreement requested by NASB. See
"Conditions to the Merger" below.

CONDITIONS TO THE MERGER

      The obligations of NASB and CBES to complete the merger are conditioned on
the following:

     o     approval of the merger agreement by CBES stockholders;

     o     receipt of all required regulatory approvals,  consents  and  waivers
           without any materially adverse conditions;

     o     no  party to the merger being subject to any order, decree, ruling or
           injunction  that  prohibits  consummating the merger, no governmental
           entity  having instituted  any proceeding for the purpose of blocking
           the  merger, and the absence  of any statute, rule or regulation that
           prohibits or restricts completion of the merger;

     o     no litigation, claim, action, suit or other  legal or  administrative
           proceeding  challenging the merger shall be pending against any party
           or any  subsidiaries, directors or officers of any party which NASB's
           counsel  believes would result in NASB paying damages  and litigation
           costs that would not be reimbursed by insurance or if NASB will  have
           to  indemnify  a person or  persons in excess of $250,000 as a result
           of such litigation,  claim,  action,  suit or other legal or adminis-
           trative proceeding; and

     o     the other party having performed in all material respects its obliga-
           tions  under the merger agreement, the other party's representations
           and  warranties  being  true and correct as of the date of the merger
           agreement and as of the closing date.

      The obligations of NASB to complete the merger are conditioned on CBES
having adjusted stockholders' equity of not less than $13,500,000. The
obligations of CBES to complete the merger also are conditioned on NASB having
sufficient cash to pay the aggregate merger consideration. NASB has advised that
the cash needed for the payment of the aggregate merger consideration will be
obtained from available cash on hand and from cash dividends provided by its
savings banking subsidiary. As a part of its due diligence investigations of
NASB, CBES reviewed the audited financial statements of NASB and, based on the
amount and nature of NASB's consolidated assets and stockholders' equity and
NASB's historical annual earnings, CBES made a favorable assessment as to NASB's
ability to pay the aggregate merger consideration.

      We cannot guarantee that all of the conditions to the merger will be
satisfied or waived by the party permitted to do so. If the merger is not
completed on or before January 31, 2002, either party may terminate the merger
agreement by a vote of a majority of its board of directors.

Conduct of Business Pending the Merger

      NASB and CBES have each agreed that, until the completion of the merger,
each of them will, and will cause its subsidiaries to, use its commercially
reasonable efforts to:

     o      conduct  its business in the regular,   ordinary  and  usual  course
            consistent with past practice;

     o      maintain and preserve intact its business organization,  properties,
            leases,  employees and   advantageous   business  relationships  and
            retain the services of its officers and key employees;

26


     o      take  no action which would adversely affect or delay the ability of
            NASB or CBES to perform their respective covenants and agreements on
            a timely basis under the merger agreement; and

     o      take  no  action  which  would adversely affect or delay any party's
            ability  to obtain  any necessary approval, consent or waiver of any
            governmental authority required for the transactions contemplated by
            the merger agreement or which would reasonably be expected to result
            in those approvals,  consents  or  waivers  containing  any material
            condition or restriction.

      Further, except as otherwise provided in the merger agreement or as
permitted by NASB, until the completion of the merger CBES has agreed that
neither it nor its subsidiaries will:

     o     change its certificate of incorporation or bylaws;

     o     authorize, issue, deliver or sell any shares of its capital stock, or
           securities or obligations convertible or  exercisable for  any shares
           of its  capital  stock, other than shares issued upon the exercise of
           outstanding stock options;

     o     issue,  grant  or  sell  any option, warrant, call, commitment, stock
           appreciation right, right to purchase or agreement  relating  to  its
           authorized or issued capital stock, or change the terms of any of its
           outstanding stock options or warrants;

     o     split, combine,  reclassify or adjust any shares of its capital stock
           or otherwise change its capitalization;

     o     make, declare or pay any cash or stock dividend or other distribution
           on its capital stock;

     o     acquire  or  sell, transfer,  assign, mortgage, encumber or otherwise
           dispose of  any  of its  material assets or cancel, release or assign
           any  indebtedness, other  than in  the ordinary  course of   business
           consistent with past practice;

     o     increase the  compensation or fringe benefits of any of its employees
           or directors;

     o     pay bonuses to its employees or directors;

     o     pay any pension or  retirement allowance not required by any existing
           plan or agreement to any employees or directors;

     o     become a party to, amend or commit to fund or otherwise establish any
           trust or account related to any employee benefit plan with or for the
           benefit of any employee or director;

     o     voluntarily  accelerate the vesting of  any  stock  option  or  other
           compensation or benefit;

     o     grant or award any stock option, or make any discretionary  contribu-
           tion to any employee benefit plan;

     o     hire any employee with annual total compensation in excess of $30,000

COVENANTS OF THE PARTIES

Agreement Not to Solicit Other Offers

    The merger agreement prohibits CBES and Community Bank and their officers,
directors, employees, representatives, agents and affiliates from directly or
indirectly initiating, soliciting, knowingly encouraging or facilitating any
acquisition proposal with a third party, or entering into discussions with any
party in furtherance of such inquiries. An acquisition proposal includes the
following:

     o     any merger, consolidation, share exchange,  business  combination  or
           other similar transaction;

     o     any sale,  lease,  exchange,  mortgage,  pledge,  transfer  or  other
           disposition  of  25% or more of the assets of CBES or Community Bank,
           taken as a whole, in  a single transaction or series of transactions;

     o     any tender offer or exchange offer for 25% or more of the outstanding
           shares  of  capital  stock  of  CBES  or the filing with the SEC of a
           registration statement for that purpose; and

     o     any public announcement of a proposal, plan or intention to do any of
           the foregoing or any agreement to engage in any of the foregoing.

      Despite the foregoing agreement not to solicit other acquisition
proposals, the board of directors of CBES may under certain circumstances
furnish information to or enter into discussions or negotiations with anyone who
makes an unsolicited, written, bona fide acquisition proposal that is a
financially superior proposal to the NASB merger. A proposal of this nature is
one upon which CBES's board has concluded, after consulting with its financial
advisors and legal counsel, that action is necessary for the board to comply
within its fiduciary duties to stockholders. Before CBES enters into
negotiations with a third party regarding a superior proposal, it has to give
reasonable notice to NASB and must obtain from the third party an executed
confidentiality agreement.

      The merger agreement requires the board to recommend that stockholders
approve and adopt the merger agreement, except to the extent legally required
for the discharge by the board of its fiduciary duties as advised by its
counsel. The merger agreement permits the board to withdraw or modify its
recommendation if an acquisition proposal is made and the board (i) has received
a written opinion from its financial advisor that such proposal may be superior
from a financial point-of-view to CBES stockholders and (ii) determines after
consultation with independent legal counsel that such action is necessary to
comply with its fiduciary duties to stockholders.

Employee Matters

      Each person who is an employee of CBES or its subsidiaries as of the
effective time of the merger and whose employment is not specifically terminated
at or prior to closing will become an employee of the combined company or its
subsidiaries. Each of these continuing employees will be an employee at will.

      All employees who continue as employees of the combined company after the
merger will be eligible to participate in NASB's benefit plans on the same basis
as a new employee of NASB. Service

29


with CBES or its subsidiaries will be treated as service with NASB for purposes
of satisfying any waiting periods, evidence of insurability requirements or the
application of any preexisting condition limitation with respect to any NASB
welfare benefit plan. Each continuing employee shall receive credit for service
with CBES or its subsidiaries for purposes of any employee benefit plans or
computing vacation pay benefits.


      Prior to September 30, 2002, Community Bank made a contribution of
approximately $24,695 to Community Bank's Employee Stock Ownership Plan for the
fiscal year ended December 31, 2002 to provide the ESOP funds to meet the ESOP's
obligations on its loan from CBES, the proceeds of which were used by the ESOP
to purchase CBES stock at the inception of the ESOP. Community Bank will make no
other contributions to the ESOP. Any merger consideration received by the plan
that remains after this loan is repaid will be allocated to the accounts of the
plan participants as investment earnings. The plan then will be terminated and
distributions of benefits under the plan will be made to participants in
accordance with the provisions of the plan.

      At its September 3, 2002 meeting, Community Bank's board adopted a
change-in-control severance plan. The plan entitles all salaried and hourly
employees, other than part-time employees or employees paid on a commission
basis, to a severance payment if the employee is terminated involuntarily, other
than for cause, (i) within six months after a change in control of Community
Bank or (ii) during the period of time commencing upon the date when the board
of directors authorizes management to negotiate the terms and conditions of a
definitive agreement with the intent of effecting a change in control and ending
on the date when a change of control occurs or the negotiations for a change in
control are terminated. An employee is also eligible to receive the severance
payment if he or she voluntarily leaves during either of the above periods due
to certain changes in his or her employment conditions or compensation. The plan
is not applicable to salaried employees who are covered by an agreement that
explicitly addresses compensation and benefits payable to them upon termination
of their employment. The amount of the payment under the plan would be equal to
(i) two weeks of base salary or hourly wages for employees who have been
employed by Community Bank for less than one year, (ii) one month of base salary
or four weeks of hourly wages for employees who have been employed by Community
Bank for more than one year but less than 11 years, or (iii) two months of base
salary or eight weeks of hourly wages for employees who have been employed by
Community Bank for 11 or more years. The transactions contemplated by the merger
agreement would constitute a change in control under the plan.


Indemnification of Directors and Officers

      NASB has agreed to indemnify and hold harmless each director and officer
of CBES and Community Bank against liability and expenses arising out of matters
existing or occurring at or before the consummation of the merger to the extent
allowed under applicable law.

Certain Other Covenants

      The merger agreement also contains other agreements relating to the
conduct of the parties before consummation of the merger, including the
following:


     o    After all required  regulatory  and  stockholder  approvals  have been
          received,  and at the request of NASB,  CBES will cause Community Bank
          to revise its loan,  litigation and real estate valuation policies and
          practices, and investment and asset/liability  management policies and
          practices,  to  conform  to those of North  American.  NASB must first
          confirm  that it is not  aware  of any fact  that  would  prevent  the
          completion of the merger.

     o    CBES and Community Bank will give NASB reasonable access during normal
          business hours to their properties,  books,  records and personnel and
          furnish all information which NASB may reasonably request.

     o    NASB or  Acquisition  Sub, with the  cooperation of CBES and Community
          Bank,  will submit all  necessary  filings and  applications  with any
          governmental entity, the approval of which is required to complete the
          merger and related transactions, and will obtain any

30


          approval,  consent or waiver of any third  party that is  required  in
          connection with the merger.

     o    NASB, Acquisition Sub and CBES will use all reasonable efforts to take
          promptly all actions necessary,  proper or advisable to consummate the
          merger.

     o    NASB and CBES  will  consult  with each  other  regarding  any  public
          statement about the merger and any filing with any governmental entity
          or with any national securities exchange.

     o    CBES will  take all  actions  necessary  to  convene a meeting  of its
          stockholders  to vote on the  merger  agreement.  The CBES  board will
          recommend at the special  stockholders'  meeting that the stockholders
          vote to approve the merger and will use its reasonable best efforts to
          solicit  stockholder  approval,  subject to the  exceptions  discussed
          under  "Covenants  of the  Parties -  Agreement  Not to Solicit  Other
          Officers" above.

     o    NASB and CBES each will notify the other of any  contract  defaults or
          other events which would  reasonably be likely to result in a material
          adverse effect on it.


TERMINATION OF THE MERGER AGREEMENT

      The merger agreement may be terminated at or prior to the completion of
the merger, either before or after any requisite stockholder approval, by:


     o    the mutual  consent of NASB and CBES in writing,  if a majority of the
          board of directors of each so determines;

     o    either party,  if a majority of its board of directors so  determines,
          in the event of a failure of the  stockholders  of CBES to approve the
          merger agreement;

     o    either party, if a required regulatory approval,  consent or waiver is
          denied or any  governmental  entity  prohibits the merger or the other
          transactions;

     o    either party,  if a majority of its board of directors so  determines,
          in the event the merger is not consummated by January 31, 2003, unless
          the failure to  consummate  by such time is due to a breach  caused by
          the party seeking to terminate;

     o    either party, if the other party makes a misrepresentation, breaches a
          warranty  or fails to  fulfill a covenant  that is not cured  within a
          specified time that would have a material  adverse effect on the party
          seeking to terminate;

     o    CBES,  if its  board of  directors  determines  that it must  accept a
          superior  offer from a third party in the  exercise  of its  fiduciary
          duties;

     o    NASB,  if there  shall  have  been a  material  adverse  change in the
          condition of CBES or  Community  Bank between the date of execution of
          the merger  agreement and the closing date and CBES fails to cure such
          change within a specified time;

     o    NASB,  if the  adjusted  stockholders'  equity of CBES at the close of
          business on the last day prior to the effective  date of the merger is
          less than $13,500,000; or

     o    NASB,  if  Phase  I and  Phase  II  environmental  assessments  of the
          property on which the primary  banking  facility of Community  Bank in
          Excelsior  Springs,  Missouri is located determine that  environmental
          clean-up costs would exceed $500,000.


EXPENSES AND TERMINATION FEE

      Each party will pay its own costs and expenses incurred in connection with
the merger.

      If CBES terminates the merger agreement in order to accept a superior
offer from a third party and within six months CBES or Community Bank enters
into an agreement with that party to effect a merger,

31


consolidation, share exchange or similar transaction, CBES will be required to
pay to NASB a termination fee of $250,000.

CHANGES IN TERMS OF THE MERGER AGREEMENT

      Before the completion of the merger, CBES may agree in writing to amend or
modify any provision of the merger agreement and any provision of the merger
agreement may be waived by the party benefited by the provision. However, after
the vote by the stockholders of CBES, no amendment or modification may be made
that would reduce the amount or change the kind of consideration to be received
by CBES stockholders under the terms of the merger, or contravene any provision
of applicable law or federal banking laws, rules and regulations.

REGULATORY APPROVALS


      Completion of the merger is subject to prior regulatory approval. The
merger of Acquisition Sub with and into CBES is subject to the approval of the
OTS. NASB filed a merger application with the OTS on October 15, 2002. The
application is now pending and action on the application is expected to be
forthcoming at or about the time of the special meeting to vote on the merger.
We are not aware of any other regulatory approvals that are required for
completion of the merger. Should any other approvals be required, we presently
contemplate that we or NASB would seek those approvals. There can be no
assurance that approval of the OTS or any other approval, if required, will be
obtained.


      The approval of any application merely implies the satisfaction of
regulatory criteria for approval, which does not include review of the merger
from the standpoint of the adequacy of the cash merger consideration to be paid
to CBES stockholders in exchange for their shares of CBES common stock.
Furthermore, regulatory approvals do not constitute an endorsement or
recommendation of the merger.

ACCOUNTING TREATMENT


      NASB will account for the merger under the purchase method of accounting.
This means that NASB and CBES will be treated as one company as of the effective
time of the merger and that NASB will record the fair value of CBES's assets and
liabilities on its financial statements. NASB will record the excess of its
purchase price over the fair value of CBES's identifiable net assets as
goodwill.


FEDERAL INCOME TAX CONSEQUENCES

      The following is a discussion of the material federal income tax
consequences of the merger to certain holders of CBES common stock. The
discussion is based upon the Internal Revenue Code (the "Code"), Treasury
Regulations, Internal Revenue Service rulings and judicial and administrative
decisions in effect as of the date of this proxy statement. This discussion
assumes that the common stock is generally held for investment. In addition,
this discussion does not address all of the tax consequences that may be
relevant to you in light of your particular circumstances or to CBES
stockholders subject to special rules, such as foreign persons, financial
institutions, tax-exempt organizations, dealers in securities or foreign
currencies, insurance companies or employees who acquired the stock pursuant to
the exercise of employee stock options or other compensation arrangements.

      The receipt of cash for CBES common stock in connection with the merger
will be a taxable transaction for federal income tax purposes to stockholders
receiving such cash. You will recognize a gain or loss measured by the
difference between your tax basis for the common stock owned by you at the time
of the merger and the amount of cash you receive for your CBES shares. Your gain
or loss will be a capital gain or loss if the common stock is a capital asset to
you. Under present law, long-term capital gain recognized by an individual (gain
from the sale of a capital asset held for more than one year) generally will be
taxed at a maximum federal income tax rate of 20%.

      The cash payments the holders of common stock will receive upon their
exchange of their common stock pursuant to the merger generally will be subject
to "backup withholding" for federal income tax purposes unless certain
requirements are met. Under federal law, the paying agent must withhold 31%

32


of the cash payments to holders of common stock to whom backup withholding
applies. The federal income tax withheld may be used by these persons to reduce
their federal income tax liability by the amount that is withheld. To avoid
backup withholding, a holder of common stock must provide the paying agent with
his or her taxpayer identification number and complete a form in which he or she
certifies that he or she has not been notified by the Internal Revenue Service
that he or she is subject to backup withholding as a result of a failure to
report interest and dividends. The taxpayer identification number of an
individual is his or her social security number.

      Neither NASB nor CBES has requested or will request a ruling from the
Internal Revenue Service as to any of the tax effects to CBES stockholders of
the transactions discussed in this proxy statement and no opinion of counsel has
been or will be rendered to CBES stockholders with respect to any of the tax
effects of the merger to holders of common stock

      The above summary of the material federal income tax consequences of the
merger is not intended as a substitute for careful tax planning on an individual
basis. In addition to the federal income tax consequences discussed above,
consummation of the merger may have significant state and local income tax
consequences that are not discussed in this proxy statement. Accordingly,
persons considering the merger are urged to consult their tax advisors with
specific reference to the effect of their own particular facts and circumstances
on the matters discussed in this proxy statement.

                   INTERESTS OF CERTAIN PERSONS IN THE MERGER

      Some of CBES's directors and officers may have interests in the merger
that are in addition to, or different from, the interests of stockholders. The
CBES board was aware of these interests and considered them in approving the
merger agreement.

STOCK OWNERSHIP


      The directors and executive officers of CBES, together with their
affiliates, beneficially owned a total of 166,014 shares of common stock
(representing 17.57% of all outstanding shares of the common stock) as of
October 15, 2002. The directors and executive officers will receive the same
consideration in the merger for their shares as the other CBES stockholders.

      As reported on Schedule 13 G/A dated September 17, 2002, filed with the
SEC, David H. Hancock is a beneficial owner of 82,100 shares of common stock of
CBES, which constitutes 9.37% of the outstanding shares of CBES as of October
15, 2002. Mr. Hancock has advised CBES that he is the owner of 4,276,801 shares
of the common stock of NASB, which constitutes 50.79% of the outstanding shares
of NASB as of October 9, 2002. Included in this amount are 272,068 share of the
common stock of NASB owned by Mr. Hancock's wife, as to which he disclaims
beneficial ownership and their inclusion in this report shall not be deemed as
an admission the Mr. Hancock is the beneficial owner of such shares for purposes
of Section 16 of the Securities and Exchange Act of 1934, as amended, or for any
other purpose.


STOCK OPTION PLAN


      The merger agreement provides that each option to purchase shares of
common stock pursuant to CBES's 1997 Stock Option and Incentive Plan that is
outstanding and unexercised on the effective time of the merger, whether or not
such option is then vested or exercisable, will automatically be deemed vested
and exercisable. Each such option will be converted on that date into the right
to receive in cash an amount equal to the difference between the per share
merger consideration (as adjusted) and the exercise price per share of the
option, multiplied by the number of shares of common stock subject to the
option. If the exercise price of any option is greater than the per share merger
consideration, such option will be cancelled without any payment being made for
it. As of October 15, 2002, the directors, the Chief Executive Officer and the
executive officers of CBES held options to purchase a total of 69,011 shares of
common stock. The following table reflects the number of vested and unvested
options, the weighted average exercise price of the options, and the amounts
payable to each director and named officer upon cancellation of their vested and
unvested options, based on the $17.50 per share merger consideration.

DIRECTOR EMERITUS AGREEMENTS

      In 1997 Community Bank established a policy of entering into director
emeritus agreements with its directors pursuant to which each director serving
at that time would be entitled upon retirement to an annual retirement benefit
based on the director's years of service on the Community Bank board of
directors, payable over a 120 month period. Upon termination following a change
in control of Community Bank, each director is entitled to a lump sum payment
equal to the amount of benefits accrued as of the last day of the calendar month
preceding the effective time. The agreements also provide for a death benefit
equal to the amount that would be paid to the director if he served continuously
until age 75 and retired on that date. The obligations are funded with life
insurance having a cash value of approximately $451,000, which is in excess of
the amount of the anticipated total liability to all active and retired
directors. The merger with NASB will constitute a change in control under the
director emeritus agreements. The following table sets forth the total payments
to be made to each current director under his director emeritus agreement,
assuming consummation of the merger occurs on December 13, 2002:

                                       Total Director

         Cecil E. Lamb                     $34,417

         Robert E. McCrorey                $18,653

         Rodney G. Rounkles                $17,034

SALARY CONTINUATION AGREEMENTS

      On February 21, 1995, Community Bank entered into salary continuation
agreements with Dennis D. Hartman, President, Margaret E. Teegarden, Savings
Department Manager and James V. Alderson, Loan Officer of Community Bank. Each
of these agreements entitles the executive to an annual retirement benefit based
on the position in which the executive is employed and the executive's years of
service to Community Bank, payable over a 180-month period. In the event the
executive is terminated or resigns following a change in control of Community
Bank, the executive is entitled to a lump sum payment equal to the amount of
benefits accrued at the time of termination or resignation. The agreements also
provide for a death benefit equal to the amount that would be paid to the
executive if he or she served continuously until age 65 and retired on that
date. The obligations are funded with life insurance having a cash value of
approximately $1.5 million, which is in excess of the amount of the anticipated
total liability to all of these executives. The merger with NASB will constitute
a change in control under the salary continuation agreements. The following
table sets forth the total payments to be made to each of these executives under
his or her salary continuation agreement if he or she is terminated or resigns
following the consummation of the merger assuming such consummation occurs on
December 13, 2002:

                                        Total Salary
              Name                  Continuation Payment
              ----                  --------------------

         Dennis D. Hartman                 $13,581

         Margaret E. Teegarden             $19,953

         James V. Alderson                 $23,295


CHANGE OF CONTROL AGREEMENTS

      On March 28, 1998, Community Bank entered into change in control severance
agreements with Dennis D. Hartman, President and Margaret E. Teegarden, Savings
Department Manager. Each of these agreements provides that in the event of a
change in control of Community Bank, the executive would be entitled to receive
a severance payment if, within 12 months after the closing date of change of
control of Community Bank, the executive is terminated without cause or there is
a material change in the executive's duties, compensation or certain other
aspects of the executive's employment arrangement resulting in his or her
resignation. The severance payment under both Mr. Hartman's and Ms. Teegarden's
agreements would be equal to 150% of their respective annual salaries during the
preceding calendar year, including bonuses and any other cash compensation paid
during that year. Following the consummation of the merger, assuming such
consummation occurs on December 13, 2002, if Mr. Hartman or Ms. Teegarden
becomes entitled to a severance payment under his or her severance agreement,
the total amount that the executive could receive under the agreement would be
approximately $132,072 and $77,660, respectively. To the extent that any such
payment would result in a "parachute payment" for purposes of Section 280G of
the Internal Revenue Code, the payment would be reduced by the amount necessary
to cause it not to be considered a parachute payment. The transactions
contemplated by the merger agreement would constitute a change in control of
Community Bank for purposes of these severance agreements.

SEVERANCE PLAN

      At its September 3, 2002 meeting, Community Bank's board adopted a
change-in-control severance plan. The plan entitles all salaried and hourly
employees, other than part-time employees or employees paid on a commission
basis, to a severance payment if the employee is terminated involuntarily, other
than for cause, (i) within six months after a change in control of Community
Bank or (ii) during the period of time commencing upon the date when the board
of directors authorized management to negotiate the terms and conditions of a
definitive agreement with the intent of effecting a change in control and ending
on the date when a change of control occurs or the negotiations for a change in
control are terminated. An employee is also eligible to receive the severance
payment if he or she voluntarily leaves

35


during either of the above periods due to certain changes in his or her
employment conditions or compensation. The plan is not applicable to salaried
employees who are covered by an agreement that explicitly addresses compensation
and benefits payable to them upon termination of their employment. The amount of
the payment under the plan would be equal to (i) two weeks of base salary or
hourly wages for employees who have been employed by Community Bank for less
than one year, (ii) one month of base salary or four weeks of hourly wages for
employees who have been employed by Community Bank for more than one year but
less than 11 years or (iii) two months of base salary or eight weeks of hourly
wages for employees who have been employed by Community Bank for 11 or more
years. If a terminated employee elects COBRA benefits pursuant to Section 4980B
of the Code, Community Bank will reimburse the employee for payments made for
such benefits to the extent Community Bank would have paid to provide the same
coverage to the employee had he or she not been terminated. Such reimbursement
shall be made for the same period of time as that for which the employee is
eligible to receive severance payments. In consideration of receiving such
severance payments and reimbursement for COBRA benefit expenses, terminated
employees must agree not to solicit other employees to leave the employment of
Community Bank and to maintain the confidentiality of all confidential
information learned during the course of employment. The transactions
contemplated by the merger agreement would constitute a change in control under
the plan.

OFFICER RETENTION BONUS AGREEMENTS

      In September 2002, Community Bank entered into a bonus agreements with
Paul L. Thomas, Chief Executive Officer, Ron Hill, Chief Financial Officer, and
certain other officers of Community Bank. Each agreement provides that if the
officer continues employment with Community Bank through the effective time of
the merger, the officer would be entitled to receive a bonus payment. If the
officer is terminated for cause prior to the effective time of the merger, the
officer would not be entitled to receive any portion of the bonus payment. If
Mr. Thomas and Mr. Hill continue their employment through the effective time of
the merger, they would be entitled to a bonus payment of $30,000 and $42,000,
respectively.

INDEMNIFICATION OF DIRECTORS AND OFFICERS

      NASB has agreed to indemnify and hold harmless each director and officer
of CBES and Community Bank for a period of six years after the merger from
liability and expenses arising out of matters existing or occurring at or prior
to the effective time of the merger, to the extent allowed under applicable law.
This indemnification would extend to liability arising out of the transactions
contemplated by the merger agreement. This includes advancing reasonable
indemnifiable expenses as they are incurred, provided the person receiving such
advances agrees to repay NASB if it is ultimately determined that such person is
not entitled to indemnification. In addition, NASB has agreed to pay up to
$50,000 of the premium required to extend CBES's director and officer liability
insurance coverage beyond the effective time of the merger for an additional
three years. This insurance policy reimburses the officers and directors of CBS
for liability and expenses arising out of matters existing or occurring at or
prior to the effective time of the merger if they are not indemnified by CBES.
In addition, the policy reimburses CBES for any money it pays to indemnify its
officers and directors, to the extent allowed under applicable law.

                          DISSENTERS' APPRAISAL RIGHTS

      Under Delaware law, if you do not wish to accept the cash consideration
provided for in the merger agreement, you have the right to dissent from the
merger and to have an appraisal of the fair value of your shares conducted by
the Delaware Court of Chancery. CBES stockholders electing to exercise
dissenters' appraisal rights must comply with the provisions of Section 262 of
the Delaware General Corporation Law in order to perfect their rights. Strict
compliance with the statutory procedures is required. A copy of Section 262 is
attached to this proxy statement as Appendix C.

      The following discussion is intended as a summary of the material
provisions of the Delaware statutory procedures required to be followed by a
CBES stockholder in order to dissent from the merger and perfect dissenters'
appraisal rights. This summary is not a complete statement of all applicable

36


requirements and is qualified in its entirety by reference to Section 262 of the
Delaware General Corporation Law, the full text of which appears in Appendix C.


      Section 262 requires that stockholders be notified at least 20 days before
the date of the special meeting to vote on the merger for which dissenters'
appraisal rights will be available. A copy of Section 262 must be included with
that notice. This proxy statement constitutes CBES's notice to its stockholders
of the availability of dissenters' appraisal rights in connection with the
merger in compliance with the requirements of Section 262. If you wish to
consider exercising your dissenters' appraisal rights, you should carefully
review the text of Section 262 contained in Appendix C. If you do not timely and
properly comply with the requirements of Section 262, you will lose your rights
under Delaware law.


      If you elect to demand appraisal of your shares of CBES common stock, you
must satisfy both of the following conditions:

      1.    You must deliver to CBES a written demand for appraisal of your
            shares of common stock before the vote with respect to the merger is
            taken. This written demand for appraisal must be in addition to and
            separate from any proxy given by you or vote by you abstaining from
            or voting against the merger. Voting against or failing to vote for
            the merger by itself does not constitute a demand for appraisal
            within the meaning of Section 262.

      2.    You must not vote in favor of the merger. An abstention or failure
            to vote will satisfy this requirement, but a vote in favor of the
            merger, by proxy or in person, will constitute a waiver of your
            dissenters' appraisal rights in respect of the shares of common
            stock so voted and will nullify any previously filed written demand
            for appraisal.

      If you fail to comply with either of these conditions and the merger
becomes effective, you will be entitled to receive the cash consideration for
your shares of common stock as provided for in the merger agreement and will
have no dissenters' appraisal rights with respect to your shares of CBES common
stock.

      All demands for appraisal must reasonably inform CBES of the identity of
the stockholder and the intention of the stockholder to demand appraisal of his
or her shares of common stock. The demand should be executed by or on behalf of
the record holder of the shares of common stock and must be delivered to the
following address prior to the time that the vote on the merger is taken at the
special meeting:

            Corporate Secretary
            CBES Bancorp, Inc.
            1001 North Jesse James Road
            Excelsior Springs, Missouri  64024

      To be effective, a demand for appraisal by a holder of common stock must
be made by or in the name of such registered stockholder, fully and correctly,
as the stockholder's name appears on his or her stock certificate(s) and cannot
be made by the beneficial owner if he or she does not also hold the shares of
record. In such cases, the beneficial holder must have the registered owner
submit the required demand in respect of his or her shares.

      If shares of common stock are owned of record in a fiduciary capacity,
such as by a trustee, guardian or custodian, execution of a demand for appraisal
should be made in that capacity. If the shares of common stock are owned of
record by more than one person, as in a joint tenancy or tenancy in common, the
demand should be executed by or for all joint owners. An authorized agent,
including one for two or more joint owners, may execute the demand for appraisal
for a stockholder of record; however, the agent must identify the record owner
or owners and expressly disclose the fact that, in executing the demand, he or
she is acting as agent for the record owner. A record owner, such as a broker,
who holds shares of common stock as a nominee for others, may exercise his or
her right of appraisal with respect to the shares of common stock held for one
or more beneficial owners, while not exercising this right for other beneficial
owners. In that case, the written demand should state the number of shares of
common stock as to which

37


appraisal is sought. Where no number of shares of common stock is expressly
mentioned, the demand will be presumed to cover all shares of common stock held
in the name of such record owner.

      If you hold your shares of common stock in a brokerage account or in other
nominee form and you wish to exercise appraisal rights, you should consult with
your broker or other nominee to determine the appropriate procedures for the
making of a demand for appraisal by such nominee. Similarly, if you participate
in the Community Bank Employee Stock Ownership Plan and you wish to exercise
appraisal rights, you should consult with the trustee of the Stock Ownership
Plan to determine the appropriate procedures for the making of a demand for
appraisal.


      Section 262 provides that within ten days after the effective time of the
merger, NASB must give written notice that the merger has become effective to
each CBES stockholder who has properly filed a written demand for appraisal and
who did not vote in favor of the merger. Within 120 days after the effective
time of the merger, either NASB or any stockholder who has complied with the
requirements of Section 262 may file a petition in the Delaware Court of
Chancery demanding a determination of the fair value of the shares held by all
stockholders entitled to appraisal. NASB has advised us that it does not
presently intend to file such a petition in the event there are dissenting
stockholders and that it has no obligation to do so. Accordingly, your failure
to file such a petition within the period specified could nullify your previous
written demand for appraisal.

      At any time within 60 days after the effective time of the merger, any
stockholder who has demanded an appraisal has the right to withdraw the demand
and to accept the cash payment specified by the merger agreement for his or her
shares of CBES common stock. If a petition for appraisal is duly filed by a
stockholder and a copy of the petition is delivered to NASB, NASB will be
obligated within 20 days after receiving service of a copy of the petition to
provide the Chancery Court with a duly verified list containing the names and
addresses of all stockholders who have demanded an appraisal of their shares of
common stock. After notice to dissenting stockholders, the Chancery Court is
empowered to conduct a hearing upon the petition, to determine those
stockholders who have complied with Section 262 and who have become entitled to
appraisal rights. The Chancery Court may require stockholders who have demanded
payment for their shares to submit their stock certificates to the Register in
Chancery for notation on the certificates of the pendency of the appraisal
proceedings. If any stockholder fails to comply with such a direction, the Court
may dismiss the proceedings as to such stockholder.


      After determination of the stockholders entitled to appraisal of their
shares of CBES common stock, the Chancery Court will appraise the shares,
determining their fair value exclusive of any element of value arising from the
accomplishment or expectation of the merger, together with a fair rate of
interest. When the value is determined, the Chancery Court will direct the
payment of this fair value, with interest accrued during the pendency of the
proceeding if the Chancery Court so determines, to the stockholders entitled to
receive the same, upon surrender by such holders of the certificates
representing such shares.

      In determining fair value, the Chancery Court is required to take into
account all relevant factors. You should be aware that the fair value of the
shares of common stock as determined under Section 262 could be more, the same,
or less than the value that you are entitled to receive pursuant to the merger
agreement.

      Costs of the appraisal proceeding may be imposed upon NASB and the
stockholders participating in the appraisal proceeding by the Chancery Court, as
the Chancery Court deems equitable in the circumstances. Upon the application of
a stockholder, the Chancery Court may order all or a portion of the expenses
incurred by any stockholder in connection with the appraisal proceeding,
including, without limitation, reasonable attorneys' fees and the fees and
expenses of experts, to be charged pro rata against the value of all shares of
common stock entitled to appraisal.

      After the effective time of the merger, any stockholder who demands
appraisal rights will not be entitled to vote shares of common stock subject to
such demand for any purpose or to receive payments of dividends or any other
distribution with respect to such shares of common stock, other than with
respect to payment as of a record date prior to the effective time of the
merger; however, if no petition for appraisal is filed within 120 days after the
effective time of the merger, or if such stockholder delivers a written

38


withdrawal of his or her demand for appraisal and an acceptance of the merger
within 60 days after the effective time of the merger, then the right of such
stockholder to appraisal will cease and such stockholder will be entitled to
receive the cash payment for shares of his or her common stock pursuant to the
merger agreement. Any withdrawal of a demand for appraisal made more than 60
days after the effective time of the merger may only be made with the written
approval of NASB and must, to be effective, be made within 120 days after the
effective time of the merger.

      The requirements of Section 262 are technical and complex. CBES
stockholders who may wish to dissent from the merger and pursue appraisal rights
should consult their legal advisers.

                              STOCKHOLDER PROPOSALS

      CBES will hold an annual meeting of stockholders only if the merger is not
approved at the special meeting to which this proxy statement pertains. If an
annual meeting is held, any CBES stockholder who intends to present a proposal
at the annual meeting must deliver the proposal to CBES at 1001 North Jesse
James Road, Excelsior Springs, Missouri 64024, Attention: Corporate Secretary,
by the applicable deadline below:


     o    If the stockholder  proposal is intended for inclusion in CBES's proxy
          materials for that meeting pursuant to Rule 14a-8 under the Securities
          Exchange  Act of 1934,  CBES must  receive the  proposal a  reasonable
          period  of time  before  CBES  begins  to print  and  mail  its  proxy
          materials.  Such proposal must also comply with the other requirements
          of the proxy solicitation rules of the SEC.

     o    CBES's  bylaws  provide  that  in  order  for a  stockholder  to  make
          nominations for the election of directors or proposals for business to
          be brought  before the annual  meeting,  a stockholder  generally must
          deliver notice of such  nominations  and/or proposals to the Secretary
          not less than 90 days prior to the date of the annual meeting, subject
          to specified exceptions.  The notice also must include the information
          specified in the bylaws.

                                    ---------

                                    ARTICLE I
                                    ---------

                                    THE MERGER
                                    ----------

     Section 1.1. Structure of the Merger. On the Effective Date (as defined in
Section 8.1 below), Acquisition Sub shall merge with and into CBES (the
"Merger"), the separate corporate existence of Acquisition Sub shall cease and
CBES shall survive and continue to as a corporation, pursuant to the provisions
of, and with the effect provided in the Delaware General Corporate Law (the
"DGCL") and The General and Business Corporation Law of Missouri (the "GBCLM").
The name of CBES, as the surviving corporation in the Merger, shall be CBES
Bancorp, Inc. From and after the Effective Date, CBES shall possess all of the
properties and rights and be subject to all of the liabilities and obligations
of CBES, all as more fully described in the DGCL and the GBCLM. NASB Holding may
at any time prior to the Effective Date change the method of effecting the
combination with CBES (including the provisions of this Article I) if and to the
extent it deems such change necessary, appropriate or desirable; provided,
however, that no such change shall (i) alter or change the amount or kind of
consideration to be issued pursuant to the Merger to holders of CBES Common
Stock (as defined in Section 1.2(a) hereof) as provided for in this Agreement or
(ii) materially impede or delay consummation of the transactions contemplated by
this Agreement.

     Section 1.2.  Effect on Shares of CBES Common Stock.
                   --------------------------------------

     (a)   On the Effective Date of the Merger, by virtue of the Merger,
automatically and without any action on the part of the holder thereof, each
share of common stock, par value .01 per share of CBES ("CBES Common Stock"),
that is issued and outstanding at the Effective Date, other than Excluded Shares
(as defined below) and including CBES Restricted Stock held pursuant to the CBES
Restricted Stock Plan (as defined in Section 1.4(b)), shall be cancelled and
cease to be outstanding and shall be converted into and become the right to
receive a cash payment equal to $17.50; provided, however, that such per share
amount shall be reduced if the Adjusted Stockholders' Equity (as defined in
Section 3.2(g) hereof) of CBES as of the close of business on the last business
day next prior to the Effective Date shall be equal or greater than $13,500,000
and less than $13,900,000, then the cash payment shall be equal to $17.05 per
share; and provided, further that if the Adjusted Stockholders' Equity is less
than $13,500,000, NASB Holding shall have the right to either (i) terminate this
Agreement pursuant to Section 7.1(g) hereof or (ii) consummate the Merger and
provide the holders of CBES Common Stock with a cash payment of $17.05 per share
(the "Merger Consideration"). After the Effective Date, no dividends or other
distributions made or payable by CBES shall accrued for the benefit of or be
payable with respect to, any CBES Common Stock.

     (b)  "Excluded Shares" shall consist of (i) shares of CBES Common Stock as
to which the respective holders thereof have properly demanded appraisal rights
and have not failed to perfect, have not effectively withdrawn and have not lost
their

                                      A-6


rights to appraisal and payment pursuant to any applicable law providing for
dissenters' or appraisal rights (the "Dissenters' Shares") and (ii) shares held
by CBES as treasury stock. After the Effective Date, no dividends or other
distributions made or payable by CBES shall accrue for the benefit of or be
payable with respect to, any Dissenters' Shares, and no interest shall accrue
with respect to payments due to holders of Dissenters' Shares, unless such
accruals are required by the DGCL or the GBCLM.

     (c)  On the Effective Date, each Excluded Share, other than Dissenters'
Shares, shall be canceled and retired and shall cease to exist, and no exchange
or payment shall be made with respect thereto. In addition, no Dissenters'
Shares shall be converted into the Merger Consideration pursuant to this Section
1.2, but instead shall be treated in accordance with the procedures set forth in
Section 1.7 of this Agreement.

     Section 1.3.  Exchange Procedures.
                   -------------------

     (a)  NASB Holding shall mail appropriate transmittal materials ("Letter of
Transmittal") as soon as reasonably practicable after the Effective Date, and in
no event later than five (5) business days thereafter, to each holder of record
of CBES Common Stock as of the Effective Date. A Letter of Transmittal will be
deemed properly completed only if accompanied by certificates representing all
shares of CBES Common Stock to be converted thereby, except as provided in
Section 1.3(h) below.

     (b)  At and after the Effective Date, each certificate ("CBES Certificate")
representing shares of CBES Common Stock immediately prior to the Effective Date
(except as specifically set forth in Section 1.2) shall represent only the right
to receive cash in an amount equal to the product of the Merger Consideration
multiplied by the number of shares of CBES Common Stock previously represented
by the CBES Certificate.

     (c)  Prior to the Effective Date, NASB Holding may select a bank or trust
company acceptable to CBES, which shall act as exchange agent (the "Exchange
Agent") for the benefit of the holders of shares of CBES Common Stock, for
exchange in accordance with this Section 1.3. If NASB Holding elects not to
select such a bank or trust company as the Exchange Agent, then NASB Bank shall
be deemed to be the Exchange Agent for all purposes under this Agreement. At the
Effective Date, NASB Holding shall transfer to the Exchange Agent, or set aside
and hold in trust for the benefit of the stockholders of CBES if NASB Bank is
the Exchange Agent, sufficient funds to pay the Merger Consideration to all the
stockholders of CBES.

     (d)  The Letter of Transmittal (which shall be subject to the reasonable
approval of CBES and NASB Holding) shall (i) specify that delivery shall be
effected, and risk of loss and title to the CBES Certificates shall pass, only
upon delivery of the CBES Certificates to the Exchange Agent, (ii) specify that
the shares of CBES Common Stock have been canceled, that the consideration to be
paid for such shares shall be paid only upon delivery and surrender of such CBES
Certificates (except as provided in Section 1.3(h) below), and that neither
dividends nor interest shall accrue on the cash consideration payable after the
Effective Date of the Merger, (iii) be in a form and

                                      A-7


contain any other provisions as NASB Holding may reasonably determine and (iv)
include instructions for use in effecting the surrender of the CBES Certificates
in exchange for the Merger Consideration. Upon the proper surrender of the CBES
Certificates to the Exchange Agent, together with a properly completed and duly
executed Letter of Transmittal, the holder of such CBES Certificates shall be
entitled to receive in exchange therefor, by transfer of immediately available
funds to such account at such financial institution as the holder shall direct,
or, at the holder's option, by check drawn on a commercial bank or a savings
bank having an office in the Kansas City metropolitan area, the amount of cash
that such CBES Certificates represent the right to receive pursuant to Section
1.3(b). CBES Certificates so surrendered shall forthwith be canceled. As soon as
practicable, but no later than the business day next following receipt of the
properly completed Letter of Transmittal and any necessary accompanying
documentation, the Exchange Agent shall distribute cash as provided herein. The
Exchange Agent shall not be entitled to vote or exercise any rights of ownership
with respect to the shares of CBES Common Stock held by it from time to time
hereunder, except that it shall receive and hold all dividends or other
distributions paid or distributed with respect to such shares for the account of
the persons entitled thereto. If there is a transfer of ownership of any shares
of CBES Common Stock not registered in the transfer records of CBES, the Merger
Consideration shall be issued to the transferee thereof if the CBES Certificates
representing such CBES Common Stock are presented to the Exchange Agent,
accompanied by all documents required, in the reasonable judgment of NASB
Holding and the Exchange Agent, (x) to evidence and effect such transfer and (y)
to evidence that any applicable stock transfer taxes have been paid.

     (e)  From and after the Effective Date, there shall be no transfers on the
stock transfer records of CBES of any shares of CBES Common Stock. If, after the
Effective Date, CBES Certificates are presented to NASB Holding, they shall be
exchanged for the Merger Consideration deliverable in respect thereof pursuant
to this Agreement in accordance with the procedures set forth in this Section
1.3.

     (f)  If NASB Bank is not acting as the Exchange Agent, any portion of the
aggregate amount of cash for the Merger Consideration, to be paid pursuant to
Section 1.2, or any proceeds from any investments thereof that remain unclaimed
by the stockholders of CBES for twelve months after the Effective Date shall be
repaid by the Exchange Agent to NASB Holding upon the written request of NASB
Holding. After such request is made, any stockholders of CBES who have not
theretofore complied with this Section 1.3 shall look only to NASB Holding for
the Merger Consideration deliverable in respect of each share of CBES Common
Stock such stockholder holds, as determined pursuant to Section 1.2 of this
Agreement, without any interest thereon. If outstanding CBES Certificates are
not surrendered prior to the date on which such payments would otherwise escheat
to or become the property of any governmental unit or agency, the unclaimed
items shall, to the extent permitted by any abandoned property, escheat or other
applicable laws, become the property of NASB Holding (and, to the extent not in
its possession, shall be paid over to it), free and clear of all claims or
interest of any person previously entitled to such claims. Notwithstanding the
foregoing, neither the Exchange Agent nor any party to this Agreement (or any
affiliate thereof) shall be

                                      A-8


liable to any former holder of CBES Common Stock for any amount delivered to a
public official pursuant to applicable abandoned property, escheat or similar
laws.

     (g)  NASB Holding and the Exchange Agent shall be entitled to rely upon
CBES's stock transfer books to establish the identity of those persons entitled
to receive the Merger Consideration, which books shall be conclusive with
respect thereto. In the event of a dispute with respect to ownership of stock
represented by any CBES Certificate, NASB Holding and the Exchange Agent shall
be entitled (i) deposit any Merger Consideration, represented thereby in escrow
with an independent third party and thereafter be relieved with respect to any
claims thereto, or (ii) to file a suit in interpleader against the competing
parties, deposit the Merger Consideration due with respect to the disputed CBES
Certificate with a court of competent jurisdiction, and thereafter be discharged
from any responsibility to the competing parties.

     (h) If any CBES Certificate shall have been lost, stolen or destroyed, upon
the making of an affidavit of that fact by the person claiming such CBES
Certificate to be lost, stolen or destroyed and, if required by the Exchange
Agent, the posting by such person of a bond in such amount as the Exchange Agent
may direct as indemnity against any claim that may be made against it with
respect to such CBES Certificate, the Exchange Agent shall pay in exchange for
such lost, stolen or destroyed CBES Certificate the Merger Consideration
deliverable in respect thereof pursuant to Section 1.2.

     Section 1.4.  Stock Options; Restricted Stock.
                   --------------------------------

     (a)  At the Effective Date, each option to acquire shares of CBES Common
Stock (a "CBES Option"), whether or not then vested, granted pursuant to the
CBES's 1997 Stock Option and Incentive Plan (the "CBES Option Plan") that is
then outstanding and unexercised shall be deemed vested and exercisable, whether
or not then exercisable, and shall be canceled and terminated and in lieu
thereof the holders of such options shall be paid by CBES in cash (from funds
provided by NASB Holding) in an amount equal to the product of (i) the number of
shares of CBES Common Stock subject to such unexercised option at the Effective
Date and (ii) the amount by which the Merger Consideration per share exceeds the
exercise price per share of such option net of any cash which must be withheld
under federal and state income and employment tax requirements. In the event
that the exercise price of a CBES Option is greater than the Merger
Consideration, then at the Effective Date such CBES Option shall be canceled
without any payment made in exchange therefore. At the Effective Date, the CBES
Option Plan shall be deemed terminated.

     (b)  Inasmuch as at the Effective Date, all shares of restricted CBES
Common Stock (the "CBES Restricted Stock"), held under the CBES Recognition and
Retention Plan (the "CBES Restricted Stock Plan") are to be canceled, and in
respect of such shares to be paid the Merger Consideration in respect of such
shares to be paid to the holders thereof. At the Effective Date, the CBES
Restricted Stock Plan shall be deemed terminated.

                                      A-9


     Section 1.5.  Directors and Officers of CBES and Community Bank at
Effective Date. The directors and officers of CBES, the directors of Community
Bank and designated officers of Community Bank shall resign effective as of the
Effective Date. Immediately thereafter, NASB Holding shall appoint new officers
and directors to CBES, each to hold office in accordance with the articles of
incorporation and bylaws of CBES until their respective successors are duly
elected or appointed and qualified. The new officers and directors of CBES shall
then appoint new officers and directors of Community Bank, each to hold office
in accordance with the articles of incorporation and bylaws of Community Bank
until their respective successors are duly elected or appointed and qualified.

     Section 1.6.  Articles of Incorporation and Bylaws of the Surviving
Corporation. The articles of incorporation (attached hereto as Exhibit A) and
bylaws of Acquisition Sub in effect immediately prior to the Effective Date
shall be the articles of incorporation and bylaws of the surviving corporation
from and after the Effective Date until amended as provided by law.

     Section 1.7.  Dissenters' Rights.
                   -------------------

     (a)  NASB Holding shall pay for any Dissenters' Shares in accordance with
applicable law providing for dissenters' or appraisal rights, and the holders
thereof shall not be entitled to receive any Merger Consideration; provided,
that if appraisal rights under applicable law with respect to any Dissenters'
Shares shall have been effectively withdrawn or lost, such shares will thereupon
cease to be treated as Dissenters' Shares and shall be converted into the right
to receive cash in an amount equal to the Merger Consideration multiplied by the
number of shares of CBES Common Stock previously represented thereby.

     (b)  CBES shall (i) give NASB Holding prompt written notice of the receipt
of any notice from a stockholder purporting to exercise any dissenters' rights,
(ii) not settle nor offer to settle any demand for payment without the prior
written consent of NASB Holding and (iii) not waive any failure to comply
strictly with any procedural requirements of applicable corporate statutes.

                                   ARTICLE II

                         Representations and Warranties
                         ------------------------------

     Section 2.1.  Disclosure Letters. Prior to the execution and delivery of
this Agreement, CBES and NASB Holding each shall have delivered to the other a
letter (each, its "Disclosure Letter") setting forth, among other things, facts,
circumstances and events the disclosure of which is required or appropriate in
relation to any or all of their respective representations and warranties (and
making specific reference to the section or subsection, as the case may be, of
this Agreement to which they relate); provided, that (a) no such fact,
circumstance or event is required to be set forth in the Disclosure Letter as an
exception to a representation or warranty if its absence is not reasonably
likely to result in the related representation or warranty being deemed untrue
or incorrect under

                                      A-10


the standards established by Section 2.2 and (b) the mere inclusion of a fact,
circumstance or event in a Disclosure Letter shall not be deemed an admission by
a party that such item represents a material exception or that such item is
reasonably likely to result in a Material Adverse Effect (as defined in Section
2.2(b)).

     Section 2.2.  Standards.
                   ----------

     (a) No representation or warranty of CBES Bank contained in Section 2.3,
and no representation or warranty of NASB Holding or Acquisition Sub contained
in Section 2.4, shall be deemed untrue or incorrect, and no party hereto shall
be deemed to have breached a representation or warranty, on account of the
existence of any fact, circumstance or event unless, as a direct or indirect
consequence of such fact, circumstance or event, individually or taken together
with all other facts, circumstances or events inconsistent with any paragraph of
Sections 2.3 or 2.4, as applicable, there is reasonably likely to exist a
Material Adverse Effect. CBES's representations, warranties and covenants
contained in this Agreement shall not be deemed to be untrue or breached as a
result of effects arising solely from actions taken pursuant to this Agreement
or in compliance with a written request of NASB Holding.

     (b) As used in this Agreement, the term "Material Adverse Effect" means an
effect which is material and adverse to the business, financial condition or
results of operations of NASB Holding, Acquisition Sub, CBES, as the context may
dictate, and its Subsidiaries (as defined herein) taken as a whole; provided,
however, that any such effect resulting from any (i) changes in laws, rules or
regulations or GAAP or regulatory accounting requirements or interpretations
thereof that apply to either NASB Holding, Acquisition Sub, and CBES, as the
case may be, or to similarly situated financial and/or depository institutions,
(ii) changes in economic conditions affecting financial institutions generally,
including but not limited to, changes in the general level of market interest
rates, (iii) fees associated with the transactions contemplated by this
Agreement or (iv) changes to this Agreement requested by NASB Holding shall not
be considered in determining if a Material Adverse Effect has occurred.

     (c) For purposes of this Agreement, "knowledge" shall mean, with respect
to a party hereto, best knowledge after a due inquiry of any of the CEO,
Chairman, Vice Chairman, President or CFO of that party.

     Section 2.3.  Representations and Warranties of CBES. Subject to Sections
2.1 and 2.2, CBES represents and warrants to NASB Holding and Acquisition Sub
that, except as disclosed in CBES's Disclosure Letter:

     (a)   Organization.
           ------------

          (i) CBES is a corporation duly organized, validly existing and in good
standing under the laws of the State of Delaware and is registered as a savings
and loan holding company under the HOLA. Community Bank is a stock savings
association duly organized, validly existing and in good standing under the laws
of the United States of America and is a wholly-owned Subsidiary (as defined
below) of CBES.

                                      A-11


Each Subsidiary of CBES other than Community Bank is a corporation, limited
liability company or partnership duly organized, validly existing and in good
standing under the laws of its jurisdiction of incorporation or organization.
Each of CBES and its Subsidiaries has all requisite corporate power and
authority to own, lease and operate its properties and to carry on its business
as now being conducted. As used in this Agreement, unless the context requires
otherwise, the term "Subsidiary" when used with respect to any party means any
corporation or other legal entity, which is consolidated with such party for
financial reporting purposes or which is controlled, directly or indirectly, by
such party through a sufficient number of shares or other evidence of ownership
of such corporation or other organization to have the power to elect a majority
of the board of directors or otherwise to control such corporation or other
organization.

          (ii) CBES and each of its Subsidiaries has the requisite corporate
power and authority and is duly qualified to do business and is in good standing
in each jurisdiction in which the nature of its business or the ownership or
leasing of its properties makes such qualification necessary.

          (iii) CBES's Disclosure Letter sets forth all of CBES's Subsidiaries
and all entities (whether corporations, partnerships or similar organizations),
including the corresponding percentage ownership, in which CBES owns, directly
or indirectly, 5% or more of the ownership interests as of the date of this
Agreement and indicates for each of CBES's Subsidiaries, as of such date, its
jurisdiction of organization and the jurisdiction(s) wherein it is qualified to
do business. All such Subsidiaries and ownership interests are in compliance
with all applicable laws, rules and regulations relating to direct investments
in equity ownership interests. CBES owns, either directly or indirectly, all of
the outstanding capital stock of each of its Subsidiaries. No Subsidiary of CBES
other than Community Bank is an "insured depository institution" as defined in
the Federal Deposit Insurance Act, as amended ("FDIA"), and the applicable
regulations thereunder. All of the shares of capital stock of CBES's
Subsidiaries are fully paid, nonassessable and not subject to any preemptive
rights and are owned by CBES or a Subsidiary of CBES free and clear of any
claims, liens, encumbrances or restrictions (other than those imposed by
applicable federal and state securities laws), and there are no agreements or
understandings with respect to the voting or disposition of any such shares.

          (iv) The deposits of Community Bank are insured by the Savings
Association Insurance Fund of the Federal Deposit Insurance Corporation ("FDIC")
to the extent provided in the FDIA.

     (b)   Capital Structure.
           -----------------

          (i) The authorized capital stock of CBES consists of 4,000,000 shares
of CBES Common Stock, par value $.01 per share, and 500,000 shares of preferred
stock, par value $.01 per share. As of the date of this Agreement (A) 1,031,851
shares of CBES Common Stock had been issued, of which 875,805 shares of CBES
Common Stock were issued and outstanding, (B) no shares of CBES preferred stock
were issued and outstanding, (C) no shares of CBES Common Stock were reserved
for

                                      A-12


issuance, except that 102,495 shares of CBES Common Stock were reserved for
issuance pursuant to the CBES Option Plan and 40,998 shares of CBES Common Stock
were reserved for issuance pursuant to the CBES Restricted Stock Plan, (D) no
shares of CBES preferred stock were held by CBES and (E) 156,046 shares of CBES
Common Stock were held by CBES in its treasury or by its Subsidiaries. The
authorized capital stock of Community Bank consists of 4,000,000 shares of
common stock, par value $.01 per share (the "Community Bank Common Stock"), and
500,000 shares of preferred stock. As of the date of this Agreement, 100 shares
of such common stock were outstanding, no shares of such preferred stock were
outstanding and all outstanding shares of such common stock were, and as of the
Effective Date will be, owned both legally and beneficially by CBES. The
authorized capital stock of Service Corporation consists of 30,000 shares of
common stock, par value $1.00 per share and no shares of preferred stock. As of
the date of this Agreement, 1,000 shares of such common stock were outstanding
and all outstanding shares of such common stock were, and as of the Effective
Date will be, owned both legally and beneficially by Community Bank. All
outstanding shares of capital stock of CBES, Community Bank and Service
Corporation are duly authorized and validly issued, fully paid and nonassessable
and not subject to any preemptive rights and, with respect to shares of CBES
held by CBES in its treasury or by its Subsidiaries and shares of Community Bank
and Service Corporation, are free and clear of all liens, claims, encumbrances
or restrictions (other than those imposed by applicable federal and state
securities laws) and there are no agreements or understandings with respect to
the voting or disposition of any such shares. CBES's Disclosure Letter sets
forth a complete and accurate list of all outstanding options to purchase CBES
Common Stock that have been granted pursuant to the CBES Option Plan, including
the names of the optionees, dates of grant, exercise prices, dates of vesting,
dates of termination and shares subject to each grant.

          (ii) No bonds, debentures, notes or other indebtedness of CBES having
the right to vote on any matters on which stockholders may vote are issued or
outstanding.

          (iii) As of the date of this Agreement, except for options granted
pursuant to the CBES Option Plan, neither CBES nor any of its Subsidiaries has
or is bound by any outstanding subscriptions, options, warrants, calls, rights,
convertible securities, commitments or agreements of any character obligating
CBES or any of its Subsidiaries to issue, deliver or sell, or cause to be
issued, delivered or sold, any additional shares of capital stock of CBES or any
of its Subsidiaries or obligating CBES or any of its Subsidiaries to grant,
extend or enter into any such option, warrant, call, right, convertible
security, commitment or agreement. As of the date hereof, there are no
outstanding contractual obligations of CBES or any of its Subsidiaries to
repurchase, redeem or otherwise acquire any shares of capital stock of CBES or
any of its Subsidiaries.

     (c)  Authority. CBES has all requisite corporate power and authority to

requisite vote of CBES's stockholders and receipt of all required regulatory or
governmental approvals, to consummate the transactions contemplated hereby. The
execution and

                                      A-13


delivery of this Agreement and, subject to the approval of this Agreement by
CBES's stockholders, the consummation of the transactions contemplated hereby,
have been duly authorized by all necessary corporate actions on the part of
CBES. This Agreement has been duly and validly executed and delivered by CBES
and constitutes a valid and binding obligation of CBES, enforceable in
accordance with its terms, subject to applicable bankruptcy, insolvency and
similar laws affecting creditors' rights and remedies generally and subject, as
to enforceability, to general principles of equity, whether applied in a court
of law or a court of equity.

     (d) Stockholder Approval; Fairness Opinion. The affirmative vote of a
majority of the outstanding shares of CBES Common Stock entitled to vote on this
Agreement is the only vote of the stockholders of CBES required for approval of
this Agreement and the consummation of the Merger and the related transactions
contemplated hereby (the "Stockholders Approvals"). CBES has received the
written opinion of Hovde Financial LLC to the effect that, as of the date
hereof, the Merger Consideration to be received by CBES's stockholders is fair,
from a financial point of view, to such stockholders.

     (e) No Violations; Consents. The execution, delivery and performance of
this Agreement by CBES does not, and the consummation of the transactions
contemplated hereby will not, constitute (i) assuming receipt of all Requisite
Regulatory Approvals (as defined in Section 2.4(d)) and requisite stockholder
approvals, a breach or violation of, or a default under, any law, rule or
regulation or any judgment, decree, order, governmental permit or license to
which CBES or any of its Subsidiaries (or any of their respective properties) is
subject, (ii) a breach or violation of, or a default under, the certificate of
incorporation or bylaws of CBES or the similar organizational documents of any
of its Subsidiaries or (iii) a breach or violation of, or a default under (or an
event which, with due notice or lapse of time or both, would constitute a
default under), or result in the termination of, accelerate the performance
required by, or result in the creation of any lien, pledge, security interest,
charge or other encumbrance upon any of the properties or assets of CBES or any
of its Subsidiaries under, any of the terms, conditions or provisions of any
note, bond, indenture, deed of trust, loan agreement or other agreement,
instrument or obligation to which CBES or any of its Subsidiaries is a party, or
to which any of their respective properties or assets may be subject. The
consummation by CBES of the transactions contemplated hereby will not require
any approval, consent or waiver under any such law, rule, regulation, judgment,
decree, order, governmental permit or license or the approval, consent or waiver
of any other party to any such agreement, or instrument, other than (x) the
approval of the holders of a majority of the outstanding shares of CBES Common
Stock entitled to vote thereon, (y) the consent of the Office of Thrift
Supervision ("OTS") and (z) such other required regulatory consents. As of the
date hereof, the executive officers of CBES know of no reason pertaining to CBES
why any of the approvals referred to in this Section 2.3(e) should not be
obtained without the imposition of any material condition or restriction
described in the last sentence of Section 5.1(b).

                                      A-14


     (f)   Reports and Financial Statements.
           --------------------------------

          (i)  CBES and each of its Subsidiaries have each timely filed all

knowledge have paid all fees and assessments due and payable in connection
therewith. As of their respective dates, none of CBES's Reports contained any
untrue statement of material fact or omitted to state a material fact required
to be stated therein or necessary to make the statements made therein, in light
of the circumstances under which they were made, not misleading. All of CBES's

Act"), and the rules and regulations of the SEC promulgated thereunder.

          (ii) Each of the financial statements of CBES included in CBES's

periods involved (except as may be indicated in the notes thereto or, in the
case of the unaudited financial statements, as permitted by the SEC). Each of
the consolidated statements of condition contained or incorporated by reference

cash flows and consolidated statements of changes in stockholders' equity,

any related notes and schedules) fairly presented (a) the financial position of
the entity or entities to which it relates as of its date and (b) the results of
operations, stockholders' equity and cash flows, as the case may be, of the
entity or entities to which it relates for the periods set forth therein
(subject, in the case of unaudited interim statements, to normal year-end
adjustments that are not material in amount or effect).

     (g)  Absence of Certain Changes or Events. Except as disclosed in CBES's
Reports filed on or prior to the date of this Agreement, since June 30, 2001,

respective businesses only in the ordinary and usual course of such businesses
consistent with their past practices and (iii) there has not been any other
event, change or occurrence or continuance of any circumstance which has had, or
is reasonably likely to have, individually or in the aggregate, a Material
Adverse Effect with respect to CBES and its Subsidiaries. To the knowledge of
CBES, there are no impending termination, expiration, or loss of contracts,
franchises, licenses, permits or other assets that, individually or in the
aggregate, are reasonably likely to have Material Adverse Effect on CBES.

                                      A-15


     (h) Absence of Claims. No litigation, controversy, claim, action, suit or
other legal administrative or arbitration proceeding before any court,
governmental agency or arbitrator is pending against CBES or any of its
Subsidiaries and to the knowledge of CBES no such litigation, controversy,
claim, action, suit or proceeding has been threatened or asserted in either case
which is reasonably likely to have a Material Adverse Effect with respect to
CBES or its Subsidiaries, or the transactions contemplated by this Agreement, or
upon the ability of CBES to perform its obligations under this Agreement. To the
knowledge of CBES, there are no investigations, reviews or inquiries by any
court or governmental agency pending or threatened against CBES or any of its
Subsidiaries.

     (i) Absence of Regulatory Actions. Except as set forth in CBES's Disclosure
Letter, neither CBES nor any of its Subsidiaries has been a party to any cease
and desist order, written agreement or memorandum of understanding with, or any
commitment letter or similar undertaking to, or has been subject to any action,
proceeding, order or directive by, or has been a recipient of any extraordinary
supervisory letter from any federal or state governmental authority charged with

Government Regulatory Agency that it is contemplating issuing or requesting (or
is considering the appropriateness of issuing or requesting) any such action,

extraordinary supervisory letter, commitment letter, board resolutions or
similar undertaking.

     (j) Taxes. All federal, state, local and foreign tax returns required to be
filed by or on behalf of CBES or any of its Subsidiaries have been timely filed
or requests for extensions have been timely filed and any such extension has
been a permitted automatic extension or has been granted and (in either case)
has not have expired, and all such filed returns are complete and accurate in
all material respects. All taxes shown on such returns, all taxes required to be
shown on returns for which extensions have been granted and all other taxes
required to be paid by CBES or any of its Subsidiaries have been paid in full or
adequate provision has been made for any such taxes, both current and deferred,

2.3(j) and Section 2.4(i), the term "taxes" shall include all income, franchise,
gross receipts, real and personal property, real property transfer and gains,
wage and employment taxes. As of the date of this Agreement, to the knowledge of
CBES, there is no audit examination, deficiency assessment, tax investigation or
refund litigation, or any threat of the foregoing, with respect to any taxes of
CBES or any of its Subsidiaries, and, to the knowledge of CBES, no claim or
threat of claim has been made by any authority in a jurisdiction where CBES or
any of its Subsidiaries do not file tax returns that CBES or any such Subsidiary
is subject to taxation in that jurisdiction. All taxes, interest, additions and
penalties due with respect to completed and settled examinations or concluded
litigation relating to CBES or any of its Subsidiaries have been paid in full or
adequate provision has been made for any such taxes on CBES 's

                                      A-16


balance sheet in accordance with GAAP. CBES and its Subsidiaries have not
executed an extension or waiver of any statute of limitations on the assessment
or collection of any material tax due that is currently in effect. CBES and each
of its Subsidiaries has withheld and paid all taxes required to have been
withheld and paid in connection with amounts paid or owing to any employee,
independent contractor, creditor, stockholder or other third party, and CBES and
each of its Subsidiaries has timely complied, in all material respects, with all
applicable information reporting requirements under Part III, Subchapter A of
Chapter 61 of the IRC and similar applicable state and local information
reporting requirements. Adequate provision for any taxes due or to become due
for CBES or any of its Subsidiaries for the period or periods reflected on
CBES's most recent financial statements has been made and is reflected on such
CBES financial statements. Deferred Taxes of CBES and its Subsidiaries have been
provided for in accordance with GAAP. To the knowledge of CBES, there is no item
of deferred taxable income which will become taxable due to the consummation of
the Merger that is reasonably likely to have a Material Adverse Effect on CBES
or its Subsidiaries, other than as disclosed in CBES's Disclosure Letter.

other documents referenced in CBES's Disclosure Letter with respect to

                                      A-17

parties sought to be bound thereby, subject to applicable bankruptcy, insolvency
and similar laws affecting creditors' rights and remedies generally and subject,
as to enforceability to general principles of equity, whether applied in a court
of law or a court of equity.

          (ii) Neither CBES nor any of its Subsidiaries is in default under (and
no event has occurred which, with due notice or lapse of time or both, would

commitment relating to any of the foregoing.

          (iv) CBES's Disclosure Letter contains a summary description of all
leases, commitments, contracts, licenses, maintenance agreements and other
agreements of CBES and its Subsidiaries involving a liability or obligation of
CBES in excess of $10,000 per annum, and a true and complete list of all letters

discount or issue a letter of credit which would aggregate in excess of $10,000
to any person, firm or corporation.

     (l) Labor Matters. CBES and its Subsidiaries are in material compliance
with all applicable laws respecting employment and employment practices, terms
and conditions of employment and wages and hours, and are not engaged in any
unfair labor practice. Neither CBES nor any of its Subsidiaries is or has ever
been a party to, or is or has ever been bound by, any collective bargaining
agreement, contract or other agreement or understanding with a labor union or
labor organization with respect to its employees, nor is CBES or any of its
Subsidiaries the subject of any proceeding asserting that it has committed an
unfair labor practice or seeking to compel it or any such Subsidiary to bargain
with any labor organization as to wages and conditions of employment nor has any
such proceeding been threatened, nor is there any strike, other labor dispute or
organizational effort involving CBES or any of its Subsidiaries pending or
threatened.

     (m) Employee Benefit Plans. CBES's Disclosure Letter contains a complete
and accurate list of all pension, retirement, stock option, stock purchase,
stock ownership, savings, stock appreciation right, profit sharing, deferred
compensation, consulting, bonus, group insurance, severance and other benefit
plans, funds, contracts,

                                      A-18


agreements and arrangements, including, but not limited to, "employee benefit
plans," as defined in Section 3(3) of the Employee Retirement Income Security
Act of 1974, as amended ("ERISA"), incentive and welfare policies, contracts,
plans and arrangements and all trust agreements related thereto with respect to
any present or former directors, officers or other employees of CBES or any of
its Subsidiaries (hereinafter collectively referred to as the "CBES Employee
Plans"). All of the CBES Employee Plans comply in all material respects with all
applicable requirements of ERISA, the IRC and other applicable laws; with
respect to the CBES Employee Plans, no event has occurred that would subject
CBES or any of its Subsidiaries to a material liability under ERISA, the IRC or
any other applicable law; there has occurred no "prohibited transaction" (as
defined in Section 406 of ERISA or Section 4975 of the IRC) which is likely to
result in the imposition of any material penalties or taxes under Section 502(i)
of ERISA or Section 4975 of the IRC upon CBES or any of its Subsidiaries; and
all required contributions to the CBES Employee Plans through the date hereof
have been made. Neither CBES nor any of its Subsidiaries has provided, or is
required to provide, security to any CBES pension plan or to any single-employer
plan of an ERISA Affiliate (as defined under Section 4001(b)(1) of ERISA or
Section 414 of the IRC) pursuant to Section 401(a)(29) of the IRC. Neither CBES,
its Subsidiaries, nor any ERISA Affiliate has contributed to any "multiemployer
plan," as defined in Section 3(37) of ERISA, on or after September 26, 1980.
Each CBES Employee Plan that is an "employee pension benefit plan" (as defined
in Section 3(2) of ERISA) and which is intended to be qualified under Section
401(a) of the IRC (a "CBES Qualified Plan") has received a favorable
determination letter from the Internal Revenue Service ("IRS"), and CBES and its
Subsidiaries are not aware of any circumstances likely to result in revocation
of any such favorable determination letter. There is no pending or threatened
litigation, administrative action or proceeding relating to any CBES Employee
Plan. There has been no announcement or commitment by CBES or any of its
Subsidiaries to amend any CBES Employee Plan, except for amendments required by
applicable law which do not materially increase the cost of such CBES Employee
Plan; and, except as specifically identified in CBES's Disclosure Letter, CBES
and its Subsidiaries do not have any obligations for post-retirement or
post-employment benefits under any CBES Employee Plan that cannot be amended or
terminated upon 60 days' notice or less without incurring any liability
thereunder, except for coverage required by Part 6 of Title I of ERISA or
Section 4980B of the IRC, or similar state laws, the cost of which is borne by
the insured individuals. The execution and delivery of this Agreement and the
consummation of the transactions contemplated hereby will not result in any
payment or series of payments by CBES or any of its Subsidiaries to any person
which is an "excess parachute payment" (as defined in Section 280G of the IRC).
To the best knowledge of CBES, no breach of a fiduciary duty under ERISA Section
404 or Section 405 has occurred and with respect to which any outstanding
liability to any participant or any material excise tax or liability exists or
will exist as of the Effective Date with respect to any of the CBES Employee
Plans. Each of the CBES Employee Plans which is a group health plan within the
meaning of IRC Section 5000(b)(1) is in compliance with the continuation of
health care coverage requirements contained in IRC Section 4980B and ERISA
Section 601 et seq. A list of participants or beneficiaries who have elected
continuation coverage in accordance with such laws is provided in CBES's
Disclosure Letter. With respect to each

                                      A-19


CBES Employee Plan, CBES will supply to NASB Bank a true and correct copy of (A)
the annual report on the applicable form of the Form 5500 series filed with the
IRS for the three most recent plan years, if required to be filed, (B) such CBES
Employee Plan, including amendments thereto, (C) each trust agreement, insurance
contract or other funding arrangement relating to such CBES Employee Plan,
including amendments thereto, (D) the most recent summary plan description and
summary of material modifications thereto for such CBES Employee Plan, if the
CBES Employee Plan is subject to Title I of ERISA, (E) the most recent actuarial
report or valuation if such CBES Employee Plan is a CBES pension plan and any
subsequent changes to the actuarial assumptions contained therein, and (F) the
most recent determination letter issued by the IRS if such CBES Employee Plan is
a CBES Qualified Plan. With respect to Community Bank's ESOP, CBES will supply
NASB Bank a true and correct copy of (A) the latest financial statement of the
ESOP including a list of assets, (B) a schedule of stock purchases by the ESOP,
including seller, valuation and number of shares, (C) a schedule of participant
name and amount, and (E) a schedule of the most recent contribution allocation
including participant name, compensation and share of contribution.

     (n) Title to Assets. CBES's Disclosure Letter contains a complete and
accurate list of all real property owned or leased by CBES or any of its
Subsidiaries, including all properties of CBES or any of its Subsidiaries
classified as "Real Estate Owned" or words of similar import (the "Real
Property"). To the knowledge of CBES, none of the buildings, structures or other
improvements located on the Real Property encroaches upon or over any adjoining
parcel or real estate or any easement or right-of-way. CBES and each of its
Subsidiaries have good and marketable title to their respective properties and
assets (including any intellectual property asset such as any trademark, service
mark, trade name or copyright) and property acquired in a judicial foreclosure
proceeding or by way of a deed in lieu of foreclosure or similar transfer
whether real or personal, tangible or intangible, reflected on the consolidated
financial statements of CBES as of June 30, 2001 or acquired after such date,
other than such items of personal property as have been disposed of in the
ordinary course of business since June 30, 2001, in each case free and clear of
any liens, security interests, encumbrances, mortgages, pledges, restrictions,
charges or rights or interests of others, except pledges to secure deposits and
other liens incurred in the ordinary course of business. Each lease pursuant to
which CBES or any of its Subsidiaries is lessee or lessor is valid and in full
force and effect and neither CBES nor any of its Subsidiaries, nor any other
party to any such lease is in default or in violation of any provisions of any
such lease. All material tangible properties of CBES and each of its
Subsidiaries are in a good state of maintenance and repair, conform with all
applicable ordinances, regulations and zoning laws and are considered by CBES to
be adequate for the current business of CBES and its Subsidiaries and
improvements on real property owned or leased by CBES are located wholly within
the boundaries of the property owned or leased by CBES or its Subsidiaries.
There are no unpaid charges, debts, liabilities, claims or obligations arising
from the construction, ownership or operation of the banking premises of
Community Bank which would give rise to any mechanics' liens against any such
real estate or any part thereof, or for which CBES or Community Bank would be
responsible, except for (i) liens imposed by law and incurred in the ordinary
course of business for obligations not

                                      A-20


yet due to carriers, warehousemen, laborers, materialmen and the like, but only
to the extent the obligation giving rise to the lien is included as a liability
on CBES's books and records and (ii) such minor encumbrances, if any, as do not
materially detract from the value of, or materially interfere with the present
use of, such properties, and which minor encumbrances do not render the title to
such property unmarketable.

     (o) Compliance with Laws. CBES and each of its Subsidiaries has all
permits, licenses, certificates of authority, orders and approvals of, and has
made all filings, applications and registrations with, all federal, state, local
and foreign governmental or regulatory bodies (each, a "Governmental Entity")
that are required in order to permit it to carry on its business as it is
presently conducted; all such permits, licenses, certificates of authority,
orders and approvals are in full force and effect, and, to the knowledge of
CBES, no suspension or cancellation of any of them is threatened. Since the date
of its incorporation, the corporate affairs of CBES have not been conducted in
violation in any material respect of any law, ordinance, regulation, order,
writ, rule, decree or approval of any Governmental Entity. Neither CBES nor any
of its Subsidiaries is in material violation of, is, to the knowledge of CBES,
under investigation with respect to any material violation of, or has been given
notice or been charged with any material violation of, any law, ordinance,
regulation, order, writ, rule, decree or condition to approval of any
Governmental Entity.

     (p) Fees. Other than financial advisory services performed for CBES by
Hovde Financial LLC, neither CBES nor any of its Subsidiaries, nor any of their
respective officers, directors, employees or agents, has employed any broker or
finder or incurred any liability for any financial advisory fees, brokerage
fees, commissions or finder's fees, and no broker or finder has acted directly
or indirectly for CBES or any of its Subsidiaries in connection with this
Agreement or the transactions contemplated hereby. CBES has provided NASB Bank
with a true and correct copy of the contract between CBES and Hovde Financial
LLC.

     (q) Environmental Matters. There is no suit, claim, action, demand,
executive or administrative order, directive, investigation or proceeding
pending or, to the knowledge of CBES, threatened before any court, Governmental
Entity or board or other forum against CBES or any of its Subsidiaries for
alleged noncompliance (including by any predecessor) with, or liability under,
any Environmental Law (as defined below) or relating to the presence of or
release into the environment of any Hazardous Material (as defined below),
whether or not occurring at or on a site owned, leased or operated by it or any
of its Subsidiaries. To CBES's knowledge, the properties currently owned or
operated by CBES or any of its Subsidiaries (including, without limitation,
soil, groundwater or surface water on, under or adjacent to the properties, and
buildings thereon) are not contaminated with and do not otherwise contain any
Hazardous Material other than as permitted under applicable Environmental Law.
Neither CBES nor any of its Subsidiaries has received any notice, demand letter,
executive or administrative order, directive, request for information or other
communication (written or oral) from any federal, state, local or foreign
Governmental Entity or any third party indicating that it may be in violation
of, or liable under, any Environmental Law. To CBES's knowledge, there are no
underground storage tanks on, in or under any properties currently owned or

                                      A-21


operated by CBES or any of its Subsidiaries and no underground storage tanks
have been closed or removed from any properties currently owned or operated by
CBES or any of its Subsidiaries. To CBES's knowledge, during the period of
CBES's or any of its Subsidiaries' ownership or operation of any of their
respective current properties, there has been no contamination by or release of
Hazardous Materials in, on, under or affecting such properties. To CBES's
knowledge, prior to the period of CBES's or any of its Subsidiaries' ownership
or operation of any of their respective current properties, there was no
contamination by or release of Hazardous Material in, on, under or affecting
such properties.

            "Environmental Law" means (i) any federal, state or local law,
statute, ordinance, rule, regulation, code, license, permit, authorization,
approval, consent, order, directive, executive or administrative order,

          (ii) The allowance for loan losses reflected in CBES's statement of
financial condition at June 30, 2002 (unaudited) was, and the allowance for loan
losses shown on the balance sheets in CBES's Reports for periods ending after

          (iii) CBES's Disclosure Letter sets forth a true and complete listing,
as of June 30, 2002, of (A) all loans, leases, advances, credit enhancements,

accordance with such initial terms, or (4) where a specific reserve allocation
exists in connection therewith, listed by category, including the amounts
thereof; and (C) Loans with any director, executive officer or five percent or

or state "anti-takeover," "fair price," "moratorium," "control share
acquisition" or similar laws or regulations.

     (t) Charter Provisions. CBES and its Subsidiaries have taken all action so

Affiliates to vote, or otherwise to exercise the rights of a stockholder with

indirectly acquired or controlled by it.

     (u) Material Interests of Certain Persons. No officer or director or 5%

insurance policies of CBES and its Subsidiaries presently in effect. In the

amounts deemed reasonable by management against such risks as companies engaged
in a similar business

                                      A-24


would, in accordance with good business practice, customarily be insured. All of
the insurance policies and bonds maintained by CBES and its Subsidiaries are in
full force and effect, CBES and its Subsidiaries are not in default thereunder
and all material claims thereunder have been filed in due and timely fashion.
CBES and its Subsidiaries have received no notice from any insurance carrier
that (i) any insurance will be canceled or that coverage thereunder will be
reduced or eliminated, or (ii) premium costs with respect to any policies of
insurance will be substantially increased.

pledges to secure FHLB borrowings, pledges to secure deposits and reverse
repurchase agreements entered into in arms-length transactions pursuant to

"held to maturity," none of the investments held by CBES or any of its
Subsidiaries as of the date of this Agreement is, or will be at Closing, subject
to any restriction (contractual or statutory) that would materially impair the
ability of the entity holding such investment freely to dispose of such
investment at any time.

exchange-traded or over-the-counter equity, interest rate, foreign exchange or
other swap, forward, future, option, cap, floor or collar or any other contract
that is a derivative contract (including various combinations thereof) or owns
securities that (a) are referred to generically as "structured notes," "high
risk mortgage derivatives," "capped floating rate notes" or "capped floating
rate mortgage derivatives" or (b) are likely to have changes in value as a
result of interest or exchange rate changes that significantly exceed normal
changes in value attributable to interest or exchange rate changes.

     (x) Credit Card Issuing Agreement. Neither CBES nor Community bank has any
credit card agreement which would prevent NASB Bank from soliciting Community
Bank's customers to accept a credit card issued by or on behalf of NASB Bank or
an Affiliate of NASB Bank.

     (y) Indemnification. Except (i) as provided in the certificate of
incorporation or bylaws of CBES and the similar governing documents of its
Subsidiaries, or (ii) as set forth in CBES's Disclosure Letter, neither CBES nor
any Subsidiary is a party to any indemnification agreement with any of its
present or former directors, officers, employees, agents or other persons who
serve or served in any other capacity with any other enterprise at the request
of CBES and, to the best knowledge of CBES, there are no claims for which any
such person would be entitled to indemnification under the articles of
incorporation or bylaws of CBES or the similar governing documents of any of its
Subsidiaries, under any applicable law or regulation or under any
indemnification agreement.

                                      A-25


     (z) Books and Records. The books and records of CBES and its Subsidiaries

incorporation, bylaws and similar governing documents of CBES and each of CBES's
Subsidiaries, as in effect as of the date of this Agreement, have previously

Subsidiaries constitute a complete and correct record of all actions taken by
their respective boards of directors (and each committee thereof) and their
stockholders.

compliance with the applicable provisions of the Community Reinvestment Act, as
amended ("CRA"), and the regulations promulgated thereunder, and, as of its most
recent CRA examination, Community Bank has a CRA rating of "Satisfactory" or
better. To CBES's knowledge, there is no fact or circumstance or set of facts or
circumstances that would cause Community Bank to fail to comply with such
provisions or cause the CRA rating of Community Bank to fall below
"Satisfactory."

     (cc) Undisclosed Liabilities. As of the date hereof, CBES and its
Subsidiaries have not incurred any debt, liability or obligation of any nature
whatsoever (whether accrued, contingent, absolute or otherwise and whether due
or to become due) except for (i) liabilities reflected on or reserved against in
the consolidated financial statements of CBES as of March 31, 2002, (ii)
liabilities incurred since June 30, 2002 in the ordinary course of business
consistent with past practice that, either alone or when combined with all
similar liabilities, have not had, and would not reasonably be expected to have,
a Material Adverse Effect on CBES and its Subsidiaries, taken as a whole, and
(iii) liabilities incurred for legal, accounting, financial advising fees and
out-of-pocket expenses in connection with a proposed sale or merger of CBES.

institution to fall below "Satisfactory." Neither NASB Holding, NASB Bank nor

     Section 4.1.  Acquisition Proposals. From and after the date hereof until
the termination of this Agreement, neither CBES nor Community Bank, nor any of
their respective officers, directors, employees, representatives, agents or
affiliates (including, without limitation, any investment banker, attorney or
accountant retained by CBES or any of its Subsidiaries), will, directly or
indirectly, initiate, solicit or knowingly encourage (including by way of
furnishing non-public information or assistance), or facilitate knowingly, any
inquiries or the making of any proposal that constitutes, or may reasonably be
expected to lead to, any Acquisition Proposal (as defined below), or enter into

(i) furnishing information to, or entering into discussions or negotiations
with, any person or entity that makes an unsolicited, written, bona fide
proposal to acquire CBES pursuant to a merger, consolidation, share exchange,
business combination, tender or exchange offer or other similar transaction, if,
and only to the extent that (A) the Board of Directors of CBES, after
consultation with and based upon the advice of independent legal counsel,
determines in good faith that such action is necessary for the Board of
Directors of CBES to comply with its fiduciary duties to stockholders under
applicable law, and (B) prior to furnishing such information to, or

                                      A-38

information to, or entering into discussions or negotiations with, such person
or entity and (y) receives from such person or entity an executed
confidentiality agreement in substantially the same form as the one heretofore
executed by NASB Holding (except that disclosure of the person's identity will
be permitted); (ii) complying with Rule 14e-2 promulgated under the Exchange Act
with regard to a tender or exchange offer; or (iii) failing to make or
withdrawing or modifying its recommendation if there exists an Acquisition
Proposal as to which the Board of Directors of CBES has received a written
opinion from its independent financial adviser that such Proposal may be
superior to the Merger from a financial point-of-view to CBES's stockholders
and, after consultation with independent legal counsel, the Board of Directors
of CBES determines in good faith that such action is necessary for the Board of
Directors of CBES to comply with its fiduciary duties to stockholders under
applicable law (any such Acquisition Proposal as to which the Board of Directors
has received the opinion and made the determination described in this clause
(iii) being referred to herein as a "Superior Proposal"). CBES shall notify NASB
Holding orally and in writing of any Acquisition Proposal (including, without
limitation, the terms and conditions of any such Acquisition Proposal and the

its Subsidiaries: (i) any merger, consolidation, share exchange, business
combination, or other similar transaction; (ii) any sale, lease, exchange,

transactions; (iii) any tender offer or exchange offer for 25% or more of the
outstanding shares of capital stock of CBES or the filing of a registration
statement under the Securities Act of 1933 in connection therewith; or (iv) any
public announcement of a proposal, plan or intention to do any of the foregoing
or any agreement to engage in any of the foregoing.

                   -------------------------------------

after the date on which all Requisite Regulatory Approvals and stockholder
approvals are received, and after receipt of written confirmation from NASB
Holding that it is not aware of any fact or circumstance that would prevent
completion of the Merger, and prior to the Effective Date; provided, however,
that CBES shall not be required to take such action more than 30 days prior to
the Effective Date; and provided, further, that such policies and procedures are
not prohibited by GAAP or any applicable laws and regulations or, in the view of

provided in order to obtain all approvals, consents and waivers of Governmental
Entities and third parties

                                      A-40

certificates of incorporation and bylaws and the provisions of any federal or
state anti-takeover laws.

and any other transaction contemplated hereby and in making any filings with any
Governmental Entity or with any national securities exchange with respect
thereto.

in accordance with applicable law and its certificate of incorporation and
bylaws, to convene a meeting of its stockholders ("Stockholder Meeting") as

thereunder and such information shall not contain any untrue statements of a
material fact or omit to state any material fact required to be stated in such
proxy statement with respect to NASB Holding or its Subsidiaries or to make the
statements therein with respect to NASB Holding or its Subsidiaries not
misleading.

     Section 4.10.  Notification of Certain Matters. Each party shall give
prompt notice to the other of: (a) any event or notice of, or other
communication relating to, a default or event that, with notice or lapse of time
or both, would become a default, received by it or any of its Subsidiaries
subsequent to the date of this Agreement and prior to the Effective Date, under
any contract material to the financial condition, properties, businesses or
results of operations of each party and its Subsidiaries taken as a whole to
which each party or any Subsidiary is a party or is subject; and (b) any event,
condition, change or occurrence which individually or in the aggregate has, or
which, so far as reasonably can be foreseen at the time of its occurrence, is
reasonably likely to result in a Material Adverse Effect with respect to such
party and its Subsidiaries taken as a whole. Each of CBES and NASB Holding shall
give prompt notice to the other party of any (i) notice or other communication
from any third party alleging that the consent of such third party is or may be
required in connection with any of the transactions contemplated by this
Agreement and (ii) the occurrence or non-occurrence of any fact or event which
would be reasonably likely to cause any representation or warranty contained in
this Agreement to be untrue or inaccurate in any respect at any time from the
date hereof to the Effective Date or to cause any covenant, condition or
agreement under this Agreement not to be complied with or satisfied in all
material respects.

     Section 4.11.  Employees.
                    ----------

     (a) All persons who are employees of Community Bank immediately prior to
the Effective Date and whose employment is not specifically terminated at or
prior to the Effective Date (a "Continuing Employee") shall, at the Effective
Date, remain employees of Community Bank. All of the Continuing Employees shall
be employed at the will of Community Bank and no contractual right to employment
shall inure to such employees because of this Agreement. NASB Holding will use
its best

                                      A-42


efforts to retain all of the employees of Community Bank, subject to the
qualifications of such employees and the needs of NASB Holding. At any time
after the receipt of the Requisite Regulatory Approvals and Stockholder approval
for the transactions contemplated by this Agreement, or by mutual consent prior
thereto, CBES shall (i) allow NASB Holding to conduct interviews with the
existing employees of CBES and Community Bank and to communicate with the
employees regarding the terms of their employment which will be in effect on or
after the Effective Date and (ii) allow NASB Bank to conduct training sessions
for employees of CBES and its Subsidiaries at NASB Bank's or Community Bank's
facilities. All such training sessions shall be scheduled so as to have minimal
impact upon the employees' performance of their normal daily duties.

     (b) Immediately following the Effective Date, each Continuing Employee
shall be eligible to participate in NASB Holding's or NASB Bank's benefit plans
on the same basis as a new employee of NASB Holding's or NASB Bank's (it being
understood that inclusion of Continuing Employees in NASB Holding's or NASB
Bank's benefit plans may occur at different times with respect to different
plans). Service with CBES or its Subsidiaries shall be treated as service with
NASB Holding or NASB Bank for purposes of satisfying any waiting periods,
evidence of insurability requirements, or the application of any preexisting
condition limitation with respect to any NASB Holding or NASB Bank "welfare
benefit plan", as defined in Section 3(1) of ERISA. Each Continuing Employee
shall receive credit for service with CBES or its Subsidiaries for purposes of
any employee benefit plans or computing vacation pay benefits.

     (c)   CBES shall retain all existing life insurance policies owned by CBES.

     (d) CBES shall not encourage the further exercise of any CBES Options and
shall advise optionees as to the payments to which they will be entitled
hereunder.

     (e) Prior to September 30, 2002, Community Bank shall fund the CBES
Employee Stock Ownership Plan (the "ESOP") with the scheduled contribution of
Twenty Four Thousand Nine Hundred Sixty Five and 80/100 Dollars ($24,965.80) to
provide the ESOP funds to pay the principal and interest due on the CBES loan to
the ESOP from CBES; provided, however, that the amount of such payment from
Community Bank to the ESOP may be adjusted if the total amount of scheduled
interest due on the loan to CBES changes due to a variation in the adjustable
interest rate of the loan; and provided, further, that if the Effective Date of
the Merger occurs after December 31, 2002, Community Bank shall fund the CBES
ESOP with the scheduled contribution payment necessary to provide the ESOP funds
to pay the principal and interest due on the CBES loan to the ESOP from CBES.

     (f) Prior to the Effective Date, the ESOP shall be amended to state that
any Merger Consideration remaining after repayment of the loan between CBES and
the ESOP shall be allocated as investment earnings of the ESOP to the ESOP
accounts of employees of Community Bank or any of its Subsidiaries who are ESOP
participants and beneficiaries ("ESOP Participants") in accordance with the
terms of the ESOP as

                                      A-43


amended with respect to such termination and as in effect on the Effective Date.
All ESOP Participants shall fully vest and have a nonforfeitable interest in
their accounts under the ESOP determined as of the Effective Date. As soon as
practicable after the Effective Date, any loan between CBES and the ESOP shall
be repaid in full from the Merger Consideration received by the ESOP for
unallocated shares of CBES Common Stock held by the ESOP upon the conversion of
such shares into cash pursuant to this Agreement. As soon as reasonably
practicable after the ESOP loan has been repaid, NASB Holding shall terminate
the ESOP and shall file an application for determination with the Internal
Revenue Service ("IRS") as to the tax qualified status of the ESOP upon its
termination under Section 401(a) and 4975(e)(7) of the IRC (the "Determination
Letter"). As soon as reasonably practicable after the receipt of a favorable
Determination Letter from the IRS, NASB Holding shall instruct the ESOP Trustee
to make distributions of the benefits under the ESOP to the ESOP Participants in
accordance with the provisions of the ESOP.

     (g) NASB Holding agrees to honor the terms and conditions of all Director
Emeritus Agreements by and between Community Bank and certain directors of
Community Bank, a copy of each of which is attached to CBES's Disclosure Letter,
and NASB Holding agrees that the benefits to be paid to each affected director
shall be the amount accrued on the books and records of Community Bank as of the
last day of the calendar month preceding the Closing Date, which amount shall
not be less than the amount shown in CBES's Disclosure Letter.

     (h) NASB Holding agrees to honor the terms and conditions of all Salary
Continuation Agreements by and between Community Bank and certain employees of
Community Bank, a copy of each of which is attached to CBES's Disclosure Letter,
and NASB Holding agrees that the benefits to be paid to each affected employee
shall be the amount accrued on the books and records of Community Bank as of the
last day of the calendar month preceding the Closing Date, which amount shall
not be less than the amount shown in CBES's Disclosure Letter.

     (i) NASB Holding agrees to honor the terms and conditions of (i) the
Community Bank Severance Plan, which Severance Plan shall not be revoked,
terminated, modified or amended by NASB Holding or its Subsidiaries or its
successors and assigns, (ii) the Employee Bonus Agreements by and between
Community Bank and certain employees of Community Bank, (iii) the Severance
Agreement, as amended, by and between Dennis D. Hartman and Community Bank and
(iv) the Severance Agreement , as amended, by and between Margaret E. Teegarden
and Community Bank; a copy of each of which is attached to CBES's Disclosure
Letter.

     Section 4.12.  Indemnification. Unless prohibited by law or regulation in
effect at the time a Claim (as defined below) is pending and except as provided
in Section 4.12(b) below, from the Effective Date through six (6) years after
the Effective Date, NASB Holding (and any successor) agrees to indemnify each
director, officer and employee of CBES and Community Bank serving in such
capacities as of the date of this Agreement (each, an "Indemnified Party"), from
and against Indemnified Payments and Indemnified Expenses (as both terms are
defined below) incurred in connection with

                                      A-44


Claims brought against any Indemnified Party, arising out of matters existing or
occurring at or prior to the Effective Date (including the transactions
contemplated by this Agreement), whether asserted or claimed prior to, at or
after the Effective Date, provided that in the case of any Claims asserted prior
to the Effective Date NASB Holding has been notified of such Claims prior to
Closing. NASB Holding further agrees, subject to applicable regulatory
restrictions, to advance any reasonable Indemnified Expenses to such Indemnified
Party as they are from time to time incurred provided that the Indemnified Party
to whom expenses are being advanced provides a written undertaking to repay such
expenses if it is ultimately determined that such person is not entitled to
Indemnification.

     (a)  As used herein, the foregoing terms have the following meanings:

          (i) A "Claim" is any threatened, pending or completed action, suit,
investigation or proceeding (whether civil, criminal, administrative or
investigative) which relates to services rendered prior to the Effective Date by
an Indemnified Party on behalf of CBES or its Subsidiaries.

          (ii) "Indemnified payments" shall mean judgments, fines and amounts
paid in settlement of Claims.

          (iii) "Indemnified expenses" shall mean all costs and expenses
(including but not limited to attorneys' fees) actually and reasonably incurred
by an Indemnified Party in connection with defending against such Claims.

     (b) NASB Holding shall not be required to indemnify any Indemnified Party
from and against Indemnified expenses and/or Indemnified payments if (i) a final
non-appealable order is entered by a court or administrative tribunal having
jurisdiction pursuant to a Claim brought by a person other than the OTS that
such Indemnified Party's conduct was knowingly fraudulent, deliberately
dishonest, or willful misconduct and the Claim giving rise to the entry of such
order was brought by a third party; or (ii) a final non-appealable order is
issued by an administrative tribunal or court having jurisdiction pursuant to a
Claim brought by the OTS or a settlement agreement is entered into between the
Indemnified Party and the OTS: (x) imposing a civil money penalty against the
Indemnified Party; (y) removing the Indemnified Party from office or prohibiting
such person from participating in the conduct of NASB Holding; or (z) directing
the Indemnified Party to cease and desist taking any of the actions set forth in
Section 8(b) of the FDIA (12 U.S.C. ss. 1818(b)).

     (c) Any Indemnified Party wishing to claim indemnification under Section
4.12, must (i) upon learning of any such Claim, promptly notify NASB Holding
thereof and provide to NASB Holding copies of all written materials related to
the Claim and any other information related to such Claim; (ii) consent to the
defense of any such Claim by competent counsel chosen by NASB Holding; and (iii)
cooperate in the defense of any such matter by offering testimony and by
complying with all reasonable requests made by NASB Holding or by counsel hired
by NASB Holding. NASB Holding shall not be liable for any settlement effected by
an Indemnified Party without its prior

                                      A-45


written consent, which consent may not be withheld unless such settlement is
unreasonable in light of such Claims against, or defenses available to, such
Indemnified Party. If NASB Holding assumes the defense of any such Claim
pursuant to this Section 4.12(c), NASB Holding shall not be liable to such
Indemnified Party for any legal expenses of additional counsel subsequently
incurred by such Indemnified Party in connection with the defense thereof. If
NASB Holding does not elect to assume such defense within thirty days from the
date NASB Holding receives notice of the Claim, the Indemnified Party may retain
counsel satisfactory to such Indemnified Party, and NASB Holding shall remain
responsible for the reasonable fees and expenses of such counsel as set forth
above.

     (d) NASB Holding shall pay all reasonable costs, including attorneys' fees
and expenses, that may be incurred by any Indemnified Party in successfully
enforcing the indemnity and other obligations provided for in this Section 4.12
to the fullest extent permitted by law. The rights of each Indemnified Party
under this paragraph (d) shall be in addition to any other right of
indemnification under this Section 4.12.

     (e) If NASB Holding or any of its successors or assigns (i) consolidates
with or merges into any other person or entity and shall not be the continuing
or surviving corporation or entity of such consolidation or merger or (ii)
transfers or conveys all or substantially all of its properties and assets to
any person or entity, then, and in each such case, to the extent necessary,
proper provision shall be made so that the successors and assigns of NASB
Holding assume the obligations set forth in this Section 4.12.

     (f) NASB Holding shall pay up to $50,000 for premiums to provide reporting
endorsement coverage under CBES's and Community Bank's current director and
officer insurance policies for each director, officer and employee of CBES and
Community Bank for a period of three (3) years.

     (g) The provisions of this Section 4.12 are intended to be for the benefit
of, and shall be enforceable by, each Indemnified Party and the heirs,
executors, and administrators of such Indemnified Party.

     Section 4.13.  Phase I and Phase II Environmental Assessments of Community
Bank's Primary Banking Facility. CBES hereby agrees that NASB Holding may cause
to be performed a Phase I and Phase II environmental assessment of the real
property on which Community Bank's primary banking facility is located (1001
North Jesse James Road, Excelsior Springs, Missouri 64024). If as a result of
such assessment it is determined that environmental clean-up costs would exceed
$500,000, then NASB Holding may elect to terminate this Agreement pursuant to
Section 7.1(h).

defense costs not covered by insurance by NASB Holding or any of its
Subsidiaries or by any person or persons whom NASB Holding would be required to
indemnify in an aggregate amount exceeding $250,000.

     Section 5.2.  Conditions to the Obligations of NASB Holding. Each of the
obligations of CBES required to be performed by it at or prior to the Closing

                                 DATA PROCESSING
                                 ---------------

members of its entire Board; or

     (b) by NASB Holding or CBES, if its Board of Directors so determines by
vote of a majority of the members of its entire Board, in the event of the
failure of the stockholders of CBES to approve the Agreement at the Stockholder
Meeting; or

     (c) by NASB Holding or CBES, by written notice to the other party, if
either (i) any approval, consent or waiver of a Government Regulatory Agency
required to permit consummation of the transactions contemplated hereby shall
have been denied or (ii) any Governmental Entity of competent jurisdiction shall
have issued a final, unappealable order enjoining or otherwise prohibiting
consummation of the transactions contemplated by this Agreement; or

                                      A-49


     (d) by NASB Holding or CBES, if its Board of Directors so determines by
vote of a majority of the members of its entire Board, in the event that the
Merger is not consummated by January 31, 2003, unless the failure to so
consummate by such time is due to the breach of any representation, warranty or
covenant contained in this Agreement by the party seeking to terminate; or

     (e) by NASB Holding or CBES (provided that the party seeking termination
is not then in material breach of any representation, warranty, covenant or
other agreement contained herein), in the event of (i) a failure to perform or
comply by the other party with any covenant or agreement of such other party
contained in this Agreement, which failure or non-compliance is material in the
context of the transactions contemplated by this Agreement, or (ii) subject to
Section 2.2(a), any inaccuracies, omissions or breach in the representations,
warranties, covenants or agreements of the other party contained in this
Agreement the circumstances as to which either individually or in the aggregate
have, or reasonably could be expected to have, a Material Adverse Effect on such
other party; in either case which has not been or cannot be cured within 30
calendar days after written notice thereof is given by the party seeking to
terminate to such other party; or

     (f) by CBES, if the Board of Directors of CBES reasonably determines by
vote of a majority of the members of its entire Board that a proposal made by a
third party to acquire, directly or indirectly, including pursuant to a tender
offer, exchange offer, merger, consolidation, business combination,
recapitalization, liquidation, dissolution or similar transaction, for
consideration consisting of cash and/or securities, more than 50% of the
combined voting power of the shares of CBES Common Stock then outstanding or all
or substantially all of the assets of CBES constitutes a Superior Proposal and
that such proposal must be accepted in order to comply with the Board of
Directors' fiduciary duties to stockholders under applicable law; provided,
however, that prior to any such termination, CBES shall use its reasonable
efforts to negotiate in good faith with NASB Holding to make such adjustments in
the terms and conditions of this Agreement that would enable CBES to proceed
with the transactions contemplated herein; or

     (g) by NASB Holding, if the Adjusted Stockholders' Equity of CBES, as
defined in Section 3.2(g) hereof, is less than $13,500,000.

     (h) by NASB Holding, if the Phase I and Phase II environmental assessments
permitted by Section 4.13 hereof determine that environmental clean-up costs
would exceed $500,000.

     Section 7.2.  Termination Fee. In the event that CBES terminates this
Agreement pursuant to Section 7.1(f) and, within six (6) months after the
termination of this Agreement, CBES or Community Bank enters into a definitive
agreement with the person that made the Superior Proposal then CBES shall,
within 10 business days following written demand by NASB Holding pay to NASB
Holding $250,000 in cash.

                                      A-50


     Section 7.3.  Effect of Termination. In the event of termination of this
Agreement by either NASB Holding or CBES prior to the consummation of the Merger
as provided in Section 7.2, this Agreement shall forthwith become void and have
no effect except (i) the obligations of the parties under Sections 4.3 (with
respect to confidentiality and the return of information), 7.2 and 9.6 shall
survive any termination of this Agreement and (ii) that notwithstanding anything
to the contrary contained in this Agreement, no party shall be relieved or
released from any liabilities or damages arising out of its willful breach of
any provision of this Agreement.

     Section 9.8.  Entire Agreement; etc. This Agreement, together with the
Disclosure Letters, represents the entire understanding of the parties hereto
with reference to the transactions contemplated hereby and supersedes any and
all other oral or written agreements heretofore made. All terms and provisions
of this Agreement shall be binding upon and shall inure to the benefit of the
parties hereto and their respective successors and assigns. Except for Sections
4.11 and 4.12 which confer rights on the parties described therein, nothing in
this Agreement is intended to confer upon any other person any rights or
remedies of any nature whatsoever under or by reason of this Agreement.

     Section 9.9.  Specific Performance. NASB Holding and CBES agree that the
franchise value of Community Bank represents a unique asset and that the failure

                                      A-53


of either party to perform the terms of this Agreement would cause irreparable
harm for which monetary damages would be totally inadequate. Therefore, either
party shall be entitled to specific performance of the terms of this Agreement.
Nothing contained in this Agreement, however, shall be deemed as granting to
NASB Holding control over CBES or Community Bank prior to the Effective Date.
Until the Requisite Regulatory Approvals and CBES's Stockholders Approvals have
been received, a breach of this Agreement by either party may be remedied only
by an action for money damages.

     Section 9.10.  Successors and Assigns; Assignment. This Agreement shall be
binding upon and inure to the benefit of the parties hereto and their respective
successors and assigns; provided, however, that this Agreement may not be
assigned by either party hereto without the written consent of the other party.


                                      A-54



            IN WITNESS WHEREOF, the parties hereto have caused this Agreement to
be executed by their duly authorized officers as of the date first above
written.

                          ARTICLE X - INDEMNIFICATION
                          ---------------------------

          (a) The  Corporation  shall indemnify any person who was or is a party
     or is threatened to be made a party to any threatened, pending or completed
     action,  suit or proceeding  whether  civil,  criminal,  administrative  or
     investigative,  other than an action by or in the right of the Corporation,
     by reason of the fact that he 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
     corporation, partnership, joint venture, trust or other enterprise, against
     expenses,  including attorneys' fees, judgments,  fines and amounts paid in
     settlement  actually and reasonably incurred by him in connection with such
     action,  suit or  proceeding  if he acted in good  faith and in a manner he
     reasonably  believed to be in or not opposed to the best  interests  of the
     Corporation, and, with respect to any criminal action or proceeding, had no
     reasonable  cause to believe his conduct was unlawful.  The  termination of
     any action, suit or proceeding by judgment order, settlement, conviction or
     upon a plea of nolo  contendere  or its  equivalent,  shall not, of itself,
     create a  presumption  that the  person  did not act in good faith and in a
     manner  which he  reasonably  believed  to be in or not opposed to the best
     interests of the  Corporation,  and, with respect to any criminal action or
     proceeding, had reasonable cause to believe that his conduct was unlawful.

          (b) The  Corporation  shall indemnify any person who was or is a party
     or is threatened to be made a party to any threatened, pending or completed
     action or suit by or in the right or the  Corporation to procure a judgment
     in its favor by reason of the fact that he 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
     corporation,  partnership, joint venture, trust or other enterprise against
     expenses,  including  attorney's  fees  and  amounts  paid  in  settlement,
     actually and reasonably  incurred by him in connection  with the defense or
     settlement  of the action or suit if he acted in good faith and in a manner
     he reasonably believed to be in or not opposed to the best interests of the
     Corporation; except that no indemnification shall be made in respect of any
     claim,  issue or matter as to which such person shall have been adjudged to
     be liable for  negligence or misconduct in the  performance  of his duty to
     the  Corporation  unless and only to the extent that the court in which the
     action or suit was brought  determines upon application  that,  despite the
     adjudication of liability and in view of all the circumstances of the case,
     the person is fairly and reasonably entitled to indemnity for such expenses
     which the court shall deem proper.

          (c) To the extent that a director,  officer,  employee or agent of the
     Corporation  has been  successful  on the merits or otherwise in defense of
     any action,  suit or proceeding referred to in Sections (a) and (b) of this
     Article,  or in defense of any claim, issue or matter therein,  he shall be
     indemnified  against  expenses,  including  attorneys'  fees,  actually and
     reasonably  incurred  by  him  in  connection  with  the  action,  suit  or
     proceeding.

          (d) Any  indemnification  under  Sections (a) and (b) of this Article,
     unless  ordered  by a  court,  shall  be  made by the  Corporation  only as
     authorized in the specific case upon a determination  that  indemnification
     of the director,  officer, employee or agent is proper in the circumstances
     because he has met the  applicable  standard  of conduct  set forth in this
     Article.  The  determination  shall be made by the Baud of Directors of the
     Corporation by a majority vote of a quorum consisting of directors who were
     not parties to the action,  suit or proceeding,  or if such a quorum is not
     obtainable,  or even if

                                      A-59


     obtainable a quorum of disinterested  Directors so directs,  by independent
     legal  counsel  in a  written  opinion,  or  by  the  shareholders  of  the
     Corporation.

          (e) Expenses incurred in defending a civil or criminal action, suit or
     proceeding  may be  paid  by  the  Corporation  in  advance  of  the  final
     disposition of the action, suit or Proceeding as authorized by the Board of
     Directors in the  specific  case upon  receipt of an  undertaking  by or an
     behalf of the  director,  officer,  employee  or agent to repay such amount
     unless  it  shall  ultimately  be  determined  that  he is  entitled  to be
     indemnified by the Corporation as authorized in this Article.

          (f) The  indemnification  provided by this Article shall not be deemed
     exclusive of any other rights to which those seeking indemnification may be
     entitled under any bylaw, agreement, vote of shareholders, or disinterested
     directors or otherwise,  both as to action in his official  capacity and as
     to action in another capacity while holding such office, and shall continue
     as to a person who has ceased to be a director,  officer, employee or agent
     and shall inure to the benefit of the heirs,  executors and  administrators
     of such person.

          (g) The Corporation may give any further indemnity, in addition to the
     indemnity authorized or contemplated under this Article,  including Section
     (f), to any person who is or was a director, officer, employee or agent, or
     to any person who is or was serving at the request of the  Corporation as a
     director,  officer, employee or agent or another corporation,  partnership,
     joint venture,  trust or other enterprise,  provided such further indemnity
     is either (i)  authorized,  directed,  or provided for in these Articles of
     Incorporation or any duly adopted  amendment thereof or (ii) is authorized,
     directed,  or provided  for in any bylaw or  agreement  of the  Corporation
     which has been adopted by a vote of the  shareholders  of the  Corporation,
     and provided further than no such indemnity shall indemnify any person from
     or on account of such persons  conduct  which was finally  adjudged to have
     been knowingly  fraudulent  deliberately  dishonest or willful  misconduct.
     Nothing  in this  Section  (g)  shall be  deemed  to limit the power of the
     Corporation  under  Section (f) of this Article to enact bylaws or to enter
     into agreements without shareholder adoption of the same.

          (h) The Corporation  may purchase and maintain  insurance on behalf of
     any  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 corporation,  partnership,
     joint venture,  trust or other  enterprise  against any liability  asserted
     against him and incurred by him in any such capacity, or arising out of his
     status as such,  whether  or not the  Corporation  would  have the power to
     indemnify him against such liability under the provisions of this Article.

          (i) For the purpose of this Article,  references to "the  Corporation"
     include all constituent  corporations absorbed in a consolidation or merger
     as well as the resulting or surviving corporation so that any person who is
     or was a  director,  officer,  employee  or  agent  of  such a  constituent
     corporation  or is or  was  serving  at the  request  of  such  constituent
     corporation  as  a  director,   officer,   employee  or  agent  of  another
     corporation,  partnership,  joint venture,  trust or other enterprise shall
     stand in the same  position  under  the  provisions  of this  Article  with
     respect to the  resulting  or surviving  corporation  as he would if he had
     served the resulting or surviving corporation in the same capacity.

                                      A-60


          (j) For purposes of this Article,  the term "other  enterprise"  shall
     include  employee  benefit plans; the term "fines" shall include any excise
     taxes  assessed on a person with respect to an employee  benefit plan;  and
     the term  "serving at the  request of the  Corporation"  shall  include any
     service as a director,  officer, employee or agent of the Corporation which
     imposes  duties  on, or  involves  services  by,  such  director,  officer,
     employee,   or  agent  with  respect  to  an  employee  benefit  plan,  its
     participants, or beneficiaries; and a person who acted in good faith and in
     a manner he reasonably  believed to be in the interest of the  participants
     and beneficiaries of an employee benefit plan shall be deemed to have acted
     in a manner  "not  opposed to the best  interests  of the  Corporation"  as
     referred to in this section.

                            ARTICLE XI - AMENDMENTS
                            -----------------------

                                      B-1

                               HOVDE FINANCIAL LLC
                   INVESTMENT BANKERS & FINANCIAL ADVISORS



September 3, 2002


Board of Directors
CBES Bancorp, Inc.
1001 North Jesse James Road
Excelsior Springs, MO 64024


Dear Members of the Board:

     We  understand  that NASB  Financial,  Inc.  ("NASB  Holding"),  a Missouri
corporation,  and CBES Bancorp,  Inc.  ("CBES"),  a Delaware  corporation,  have
entered into an Agreement and Plan of Merger (the  "Agreement")  dated September
3, 2002  pursuant  to which  CBES will  merge  with and into NASB  Holding  (the
"Merger").  As set forth in Section 1.1 of the Agreement,  at the Effective Time
of the Merger (as defined in the Agreement)  each of the  outstanding  shares of
CBES common stock ("CBES  Common  Stock"),  par value $0.01 per share,  shall be
converted into the right to receive a cash amount equal to seventeen dollars and
fifty cents ($17.50) (the "Merger Consideration").  In connection therewith, you
have requested our opinion as to the fairness,  from a financial  point of view,
of the Merger Consideration to the shareholders of CBES.

     Hovde Financial LLC ("Hovde"),  as part of its investment banking business,
is continually  engaged in the valuation of businesses  and their  securities in
connection with mergers and acquisitions, negotiated underwritings,  competitive
bidding,  secondary  distributions  of listed and unlisted  securities,  private
placements  and  valuations  for estate,  corporate and other  purposes.  We are
familiar with CBES,  having acted as its financial  advisor in connection  with,
and having  participated in the negotiations  leading to, the Agreement.  As you
are  aware,  in the course of its daily  trading  activities,  investment  funds
controlled  by an affiliate  (as such term is defined in Rule 12b-2  promulgated
under  the  Securities  Exchange  Act of 1934,  as  amended)  of Hovde and their
affiliates may from time to time effect transactions and hold securities of NASB
Holding and CBES. As of the date hereof, no shares of either NASB Holding common
stock or CBES Common Stock are owned.

     We were retained by CBES to act as its financial advisor in connection with
the  Merger.  We will  receive  compensation  from CBES in  connection  with our
services,  a significant portion of which is contingent upon the consummation of
the Merger.  CBES has agreed to indemnify us for certain liabilities arising out
of our engagement.

     During the course of our engagement and for the purposes of the opinion set
forth herein, we have:

                                      B-2


   (i)    reviewed the Agreement;

   (ii)   reviewed certain historical  publicly available business and financial
          information concerning NASB Holding and CBES;

   (iii)  reviewed  certain  internal  financial  statements and other financial
          and operating data concerning NASB Holding and CBES;

   (iv)   analyzed certain financial  projections prepared by the managements of
          CBES;

   (v)    reviewed  historical market prices and trading volumes for CBES Common
          Stock,

   (vi)   reviewed the terms of recent merger and acquisition  transactions,  to
          the extent  publicly  available,  involving  thrift and thrift holding
          companies that we considered relevant;

   (vii)  analyzed the pro forma impact of the Merger on the combined  company's
          earnings per share, consolidated capitalization and financial ratios;

   (viii) performed such other analyses and considered such other factors as  we
          have deemed appropriate.

     We also took into account our  assessment of general  economic,  market and
financial  conditions and our experience in other  transactions,  as well as our
knowledge  of the banking  industry  and our general  experience  in  securities
valuations.

     In  rendering   this  opinion,   we  have  assumed,   without   independent
verification,   the  accuracy  and  completeness  of  the  financial  and  other
information  and  representations  contained in the materials  provided to us by
NASB  Holding  and  CBES  and in the  discussions  with  NASB  Holding  and CBES
management.  In that  regard,  we have  assumed  that the  financial  forecasts,
including,  without limitation,  the projections regarding  under-performing and
non-performing  assets and net charge-offs  have been  reasonably  prepared on a
basis  reflecting the best  currently  available  information  and judgments and
estimates of NASB Holding and CBES and that such  forecasts  will be realized in
the amounts  and at the times  contemplated  thereby.  We are not experts in the
evaluation of loan and lease  portfolios  for purposes of assessing the adequacy
of the  allowances  for losses with  respect  thereto and have assumed that such
allowances for NASB Holding and CBES are in the aggregate adequate to cover such
losses. We were not retained to and did not conduct a physical inspection of any
of the  properties or  facilities of NASB Holding or CBES. In addition,  we have
not reviewed individual credit files nor have we made an independent  evaluation
or appraisal of the assets and  liabilities of NASB Holding and CBES and we were
not furnished with any such evaluations or appraisals.

     We have  assumed  that the  Merger  will be  consummated  substantially  in
accordance  with the terms set forth in the Agreement.  We have further  assumed
that the Merger will be accounted  for as a purchase  under  generally  accepted
accounting

                                      B-3


principles and that it will not qualify as a tax-free  reorganization for United
States federal income tax purposes. We have assumed that the Merger is, and will
be, in  compliance  with all laws and  regulations  that are  applicable to NASB
Holding  and CBES.  In  rendering  this  opinion,  we have been  advised by NASB
Holding and CBES and we have assumed that there are no factors that would impede
any  necessary  regulatory  or  governmental  approval of the Merger and we have
further  assumed that, in the course of obtaining the necessary  regulatory  and
governmental  approvals,  no restriction  will be imposed on NASB Holding or the
surviving  corporation that would have a material adverse effect on NASB Holding
or the  contemplated  benefits of the Merger.  We have also  assumed  that there
would not occur any change in applicable  law or  regulation  that would cause a
material  adverse  change in the  prospects or operations of NASB Holding or the
surviving corporation after the Merger.

     Our opinion is based solely upon the  information  available to us, and the
economic,  market and other circumstances,  as they exist as of the date hereof.
Events  occurring and information  that becomes  available after the date hereof
could  materially  affect the  assumptions  and analyses used in preparing  this
opinion.  We have not undertaken to reaffirm or revise this opinion or otherwise
comment upon any events  occurring or information  that becomes  available after
the date hereof, except as otherwise agreed in our engagement letter.

     We are not expressing any opinion herein as to constitute a  recommendation
to any  holder  of CBES  Common  Stock as to how such  holder  should  vote with
respect to the Agreement at any meeting of holders of CBES Common Stock.

     This letter is solely for the information of the Board of Directors of CBES
and is not to be used, circulated, quoted or otherwise referred to for any other
purpose,  nor is it to be filed with,  included in or referred to in whole or in
part in any  registration  statement,  proxy  statement  or any other  document,
except in each case in accordance with our prior written consent which shall not
be  unreasonably  withheld;  provided,  however,  that we hereby  consent to the
inclusion  and  reference to this letter in any  registration  statement,  proxy
statement, information statement or tender offer document to be delivered to the
holders of CBES Common Stock in  connection  with the Merger if and only if this
letter is quoted in full or  attached  as an exhibit to such  document  and this
letter has not been withdrawn prior to the date of such document.

     Subject to the foregoing and based on our experience as investment bankers,
our activities and  assumptions  as described  above,  and other factors we have
deemed  relevant,  we are of the  opinion as of the date  hereof that the Merger
Consideration pursuant to the Agreement is fair, from a financial point of view,
to the shareholders of CBES.

                              Sincerely,

                             /s/ Hovde Financial LLC

        APPENDIX C-- SECTION 262 OF THE DELAWARE GENERAL CORPORATION LAW


TEXT OF SECTION 262 OF THE DELAWARE GENERAL CORPORATION LAW

      APPRAISAL RIGHTS. - (a) Any stockholder of a corporation of this State who
holds shares of stock on the date of the making of a demand pursuant to
subsection (d) of this section with respect to such shares, who continuously
holds such shares through the effective date of the merger or consolidation, who
has otherwise complied with subsection (d) of this section and who has neither
voted in favor of the merger or consolidation nor consented thereto in writing
pursuant to ss. 228 of this title shall be entitled to an appraisal by the Court
of Chancery of the fair value of the stockholder's shares of stock under the
circumstances described in subsections (b) and (c) of this section. As used in
this section, the word "stockholder" means a holder of record of stock in a
stock corporation and also a member of record of a nonstock corporation; the
words "stock" and "share" mean and include what is ordinarily meant by those
words and also membership or membership interest of a member of a nonstock
corporation; and the words "depository receipt" mean a receipt or other
instrument issued by a depository representing an interest in one or more
shares, or fractions thereof, solely of stock of a corporation, which stock is
deposited with the depository.

      (b) Appraisal rights shall be available for the shares of any class or
series of stock of a constituent corporation in a merger or consolidation to be
effected pursuant to ss. 251 (other than a merger effected pursuant to ss.
251(g) of this title), ss. 252, ss. 254, ss. 257, ss. 258, ss. 263 or ss. 264 of
this title:

      (1) Provided, however, that no appraisal rights under this section shall
be available for the shares of any class or series of stock, which stock, or
depository receipts in respect thereof, at the record date fixed to determine
the stockholders entitled to receive notice of and to vote at the meeting of
stockholders to act upon the agreement of merger or consolidation, were either
(i) listed on a national securities exchange or designated as a national market
system security on an interdealer quotation system by the National Association
of Securities Dealers, Inc. or (ii) held of record by more than 2,000 holders;
and further provided that no appraisal rights shall be available for any shares
of stock of the constituent corporation surviving a merger if the merger did not
require for its approval the vote of the stockholders of the surviving
corporation as provided in subsection (f) of ss. 251 of this title.

      (2) Notwithstanding paragraph (1) of this subsection, appraisal rights
under this section shall be available for the shares of any class or series of
stock of a constituent corporation if the holders thereof are required by the
terms of an agreement of merger or consolidation pursuant to ss.ss. 251, 252,
254, 257, 258, 263 and 264 of this title to accept for such stock anything
except:

      a. Shares of stock of the corporation surviving or resulting from such
merger or consolidation, or depository receipts in respect thereof;

      b. Shares of stock of any other corporation, or depository receipts in
respect thereof, which shares of stock (or depository receipts in respect
thereof) or depository receipts at the effective date of the merger or
consolidation will be either listed on a national securities exchange or
designated as a national market system security on an interdealer quotation
system by the National Association of Securities Dealers, Inc. or held of record
by more than 2,000 holders;

      c. Cash in lieu of fractional shares or fractional depository receipts
described in the foregoing subparagraphs a. and b. of this paragraph; or

      d. Any combination of the shares of stock, depository receipts and cash
in lieu of fractional shares or fractional depository receipts described in
the foregoing subparagraphs a., b. and c. of this paragraph.

      (3) In the event all of the stock of a subsidiary Delaware corporation
party to a merger effected underss.253 of this title is not owned by the parent
corporation immediately prior to the merger, appraisal rights shall be available
for the shares of the subsidiary Delaware corporation.

                                      C-1


      (c) Any corporation may provide in its certificate of incorporation that
appraisal rights under this section shall be available for the shares of any
class or series of its stock as a result of an amendment to its certificate of
incorporation, any merger or consolidation in which the corporation is a
constituent corporation or the sale of all or substantially all of the assets of
the corporation. If the certificate of incorporation contains such a provision,
the procedures of this section, including those set forth in subsections (d) and
(e) of this section, shall apply as nearly as is practicable.

      (d) Appraisal rights shall be perfected as follows:

      (1) If a proposed merger or consolidation for which appraisal rights are
provided under this section is to be submitted for approval at a meeting of
stockholders, the corporation, not less than 20 days prior to the meeting, shall
notify each of its stockholders who was such on the record date for such meeting
with respect to shares for which appraisal rights are available pursuant to
subsection (b) or (c) hereof that appraisal rights are available for any or all
of the shares of the constituent corporations, and shall include in such notice
a copy of this section. Each stockholder electing to demand the appraisal of
such stockholder's shares shall deliver to the corporation, before the taking of
the vote on the merger or consolidation, a written demand for appraisal of such
stockholder's shares. Such demand will be sufficient if it reasonably informs
the corporation of the identity of the stockholder and that the stockholder
intends thereby to demand the appraisal of such stockholder's shares. A proxy or
vote against the merger or consolidation shall not constitute such a demand. A
stockholder electing to take such action must do so by a separate written demand
as herein provided. Within 10 days after the effective date of such merger or
consolidation, the surviving or resulting corporation shall notify each
stockholder of each constituent corporation who has complied with this
subsection and has not voted in favor of or consented to the merger or
consolidation of the date that the merger or consolidation has become effective;
or

      (2) If the merger or consolidation was approved pursuant to ss. 228 or ss.
253 of this title, then either a constituent corporation before the effective
date of the merger or consolidation or the surviving or resulting corporation
within 10 days thereafter shall notify each of the holders of any class or
series of stock of such constituent corporation who are entitled to appraisal
rights of the approval of the merger or consolidation and that appraisal rights
are available for any or all shares of such class or series of stock of such
constituent corporation, and shall include in such notice a copy of this
section. Such notice may, and, if given on or after the effective date of the
merger or consolidation, shall, also notify such stockholders of the effective
date of the merger or consolidation. Any stockholder entitled to appraisal
rights may, within 20 days after the date of mailing of such notice, demand in
writing from the surviving or resulting corporation the appraisal of such
holder's shares. Such demand will be sufficient if it reasonably informs the
corporation of the identity of the stockholder and that the stockholder intends
thereby to demand the appraisal of such holder's shares. If such notice did not
notify stockholders of the effective date of the merger or consolidation, either
(i) each such constituent corporation shall send a second notice before the
effective date of the merger or consolidation notifying each of the holders of
any class or series of stock of such constituent corporation that are entitled
to appraisal rights of the effective date of the merger or consolidation or (ii)
the surviving or resulting corporation shall send such a second notice to all
such holders on or within 10 days after such effective date; provided, however,
that if such second notice is sent more than 20 days following the sending of
the first notice, such second notice need only be sent to each stockholder who
is entitled to appraisal rights and who has demanded appraisal of such holder's
shares in accordance with this subsection. An affidavit of the secretary or
assistant secretary or of the transfer agent of the corporation that is required
to give either notice that such notice has been given shall, in the absence of
fraud, be prima facie evidence of the facts stated therein. For purposes of
determining the stockholders entitled to receive either notice, each constituent
corporation may fix, in advance, a record date that shall be not more than 10
days prior to the date the notice is given, provided, that if the notice is
given on or after the effective date of the merger or consolidation, the record
date shall be such effective date. If no record date is fixed and the notice is
given prior to the effective date, the record date shall be the close of
business on the day next preceding the day on which the notice is given.

      (e) Within 120 days after the effective date of the merger or
consolidation, the surviving or resulting corporation or any stockholder who has
complied with subsections (a) and (d) hereof and who is otherwise entitled to
appraisal rights, may file a petition in the Court of Chancery demanding a

                                      C-2


determination of the value of the stock of all such stockholders.
Notwithstanding the foregoing, at any time within 60 days after the effective
date of the merger or consolidation, any stockholder shall have the right to
withdraw such stockholder's demand for appraisal and to accept the terms offered
upon the merger or consolidation. Within 120 days after the effective date of
the merger or consolidation, any stockholder who has complied with the
requirements of subsections (a) and (d) hereof, upon written request, shall be
entitled to receive from the corporation surviving the merger or resulting from
the consolidation a statement setting forth the aggregate number of shares not
voted in favor of the merger or consolidation and with respect to which demands
for appraisal have been received and the aggregate number of holders of such
shares. Such written statement shall be mailed to the stockholder within 10 days
after such stockholder's written request for such a statement is received by the
surviving or resulting corporation or within 10 days after expiration of the
period for delivery of demands for appraisal under subsection (d) hereof,
whichever is later.

      (f) Upon the filing of any such petition by a stockholder, service of a
copy thereof shall be made upon the surviving or resulting corporation, which
shall within 20 days after such service file in the office of the Register in
Chancery in which the petition was filed a duly verified list containing the
names and addresses of all stockholders who have demanded payment for their
shares and with whom agreements as to the value of their shares have not been
reached by the surviving or resulting corporation. If the petition shall be
filed by the surviving or resulting corporation, the petition shall be
accompanied by such a duly verified list. The Register in Chancery, if so
ordered by the Court, shall give notice of the time and place fixed for the
hearing of such petition by registered or certified mail to the surviving or
resulting corporation and to the stockholders shown on the list at the addresses
therein stated. Such notice shall also be given by 1 or more publications at
least 1 week before the day of the hearing, in a newspaper of general
circulation published in the City of Wilmington, Delaware or such publication as
the Court deems advisable. The forms of the notices by mail and by publication
shall be approved by the Court, and the costs thereof shall be borne by the
surviving or resulting corporation.

      (g) At the hearing on such petition, the Court shall determine the
stockholders who have complied with this section and who have become entitled to
appraisal rights. The Court may require the stockholders who have demanded an
appraisal for their shares and who hold stock represented by certificates to
submit their certificates of stock to the Register in Chancery for notation
thereon of the pendency of the appraisal proceedings; and if any stockholder
fails to comply with such direction, the Court may dismiss the proceedings as to
such stockholder.

      (h) After determining the stockholders entitled to an appraisal, the Court
shall appraise the shares, determining their fair value exclusive of any element
of value arising from the accomplishment or expectation of the merger or
consolidation, together with a fair rate of interest, if any, to be paid upon
the amount determined to be the fair value. In determining such fair value, the
Court shall take into account all relevant factors. In determining the fair rate
of interest, the Court may consider all relevant factors, including the rate of
interest which the surviving or resulting corporation would have had to pay to
borrow money during the pendency of the proceeding. Upon application by the
surviving or resulting corporation or by any stockholder entitled to participate
in the appraisal proceeding, the Court may, in its discretion, permit discovery
or other pretrial proceedings and may proceed to trial upon the appraisal prior
to the final determination of the stockholder entitled to an appraisal. Any
stockholder whose name appears on the list filed by the surviving or resulting
corporation pursuant to subsection (f) of this section and who has submitted
such stockholder's certificates of stock to the Register in Chancery, if such is
required, may participate fully in all proceedings until it is finally
determined that such stockholder is not entitled to appraisal rights under this
section.

      (i) The Court shall direct the payment of the fair value of the shares,
together with interest, if any, by the surviving or resulting corporation to the
stockholders entitled thereto. Interest may be simple or compound, as the Court
may direct. Payment shall be so made to each such stockholder, in the case of
holders of uncertificated stock forthwith, and the case of holders of shares
represented by certificates upon the surrender to the corporation of the
certificates representing such stock. The Court's decree may be enforced as
other decrees in the Court of Chancery may be enforced, whether such surviving
or resulting corporation be a corporation of this State or of any state.

                                      C-3


      (j) The costs of the proceeding may be determined by the Court and taxed
upon the parties as the Court deems equitable in the circumstances. Upon
application of a stockholder, the Court may order all or a portion of the
expenses incurred by any stockholder in connection with the appraisal
proceeding, including, without limitation, reasonable attorney's fees and the
fees and expenses of experts, to be charged pro rata against the value of all
the shares entitled to an appraisal.

      (k) From and after the effective date of the merger or consolidation, no
stockholder who has demanded appraisal rights as provided in subsection (d) of
this section shall be entitled to vote such stock for any purpose or to receive
payment of dividends or other distributions on the stock (except dividends or
other distributions payable to stockholders of record at a date which is prior
to the effective date of the merger or consolidation); provided, however, that
if no petition for an appraisal shall be filed within the time provided in
subsection (e) of this section, or if such stockholder shall deliver to the
surviving or resulting corporation a written withdrawal of such stockholder's
demand for an appraisal and an acceptance of the merger or consolidation, either
within 60 days after the effective date of the merger or consolidation as
provided in subsection (e) of this section or thereafter with the written
approval of the corporation, then the right of such stockholder to an appraisal
shall cease. Notwithstanding the foregoing, no appraisal proceeding in the Court
of Chancery shall be dismissed as to any stockholder without the approval of the
Court, and such approval may be conditioned upon such terms as the Court deems
just.

      (l) The shares of the surviving or resulting corporation to which the
shares of such objecting stockholders would have been converted had they
assented to the merger or consolidation shall have the status of authorized and
unissued shares of the surviving or resulting corporation.
