                            AND MNB BANCSHARES, INC.
                                 ANNOUNCE MERGER

     April 19, 2001 -- Landmark Bancshares,  Inc. (NASDAQ-NMS -- "LARK"),  Dodge
City,  Kansas,  the holding  company for Landmark  Federal  Savings Bank and MNB
Bancshares,  Inc. (NASDAQ Small Cap Market -- "MNBB"),  Manhattan,  Kansas,  the
holding  company for Security  National Bank,  announced the signing today of an
Agreement and Plan of Merger (the "Agreement"). The transaction is structured as
a merger of equals  and will be  accounted  for  under  the  purchase  method of
accounting.

The transaction  will create a twelve-branch  network covering eight counties in
Kansas.  With total  combined  assets of  approximately  $378  million,  the new
organization  will rank as the third  largest  public  bank  holding  company in
Kansas.

After the closing of this  transaction,  Larry  Schugart,  President  and CEO of
Landmark, will become Chairman of the Board of the resulting company and Patrick
L.  Alexander,  President  and CEO of  MNB,  will  become  President  and  Chief
Executive  Officer  of the  resulting  company.  The Board of  Directors  of the
resulting  company  will consist of the five members from the Board of Directors
of Landmark and five members from the Board of Directors of MNB.

Larry  Schugart,  President  of  Landmark,  said,  "We  are  excited  about  our
affiliation  with MNB Bancshares and Security  National Bank. The combination of
Landmark  and MNB will  create  a  larger  financial  institution  with  greater
resources   and   products  by  combining   the   strengths   and   geographical
diversification  of both  companies.  We believe  that the merger  will  enhance
long-term  stockholder value and provide the opportunity to offer more financial
services  to the  customers,  residences  and  businesses  in  our  communities.
Although our institution has been a leading residential lender in the markets we
serve,  in recent  years our focus has  expanded to small

                                       1


business  and  consumer  lending.  With the  impending  merger  and  change to a
commercial bank charter,  while we will maintain our community focus,  expansion
into serving the business needs of our market will be enhanced."

Patrick  Alexander,  President of MNB, said, "We look forward to our merger with
Landmark.  Both  institutions  have grown and  prospered as community  financial
institutions,  and we now will be able to provide  services and products at more
offices  over an  expanded  geographical  area.  The  increased  asset  size and
resulting  stockholders'  equity  are  expected  to  improve  profitability  and
stockholder  value and provide a more liquid trading market for the stock of the
resulting company."

Pursuant  to  the  Merger  Agreement,   Landmark  and  MNB  will  merge  into  a
newly-formed  corporation,  Landmark Merger Company, which at the closing of the
merger  will  change it name to  Landmark  Bancshares,  Inc.  As a result of the
merger,  each  issued and  outstanding  share of Landmark  common  stock will be
converted  into the right to receive 1.0 shares of the new company  common stock
and each issued and outstanding share of MNB common stock will be converted into
the right to receive .523 shares of the new company common stock. At the closing
of the merger,  Landmark Federal will merge with and into Security National Bank
which will change its name to Landmark  National Bank.  After the merger,  it is
expected that the combined  company's  common stock will be traded on the Nasdaq
National Market System under the symbol "LARK."

Both  Presidents  observed that the combined  company will be well  capitalized,
with a total equity to assets ratio in excess of 10% and a tangible equity ratio
of about 9.5%. The combined  company expects to pay a quarterly cash dividend of
15 cents per  common  share or an  equivalent  of about 7.8 cents per MNB common
share, up about 20% for MNB shareholders.  This strategic  alliance will combine
two bank operations,  which geographically  compliment each other with no direct
overlap.  As a result, all branches will remain open and customers can expect to
deal with the same  individuals  they have put their trust in through the years.
While the headquarters will be in Manhattan, corporate functions are anticipated
to be shared between Dodge City and Manhattan.

Following the merger,  the Landmark and MNB shareholders  will own approximately
60% and 40% of the  combined  company,  respectively.  Based on the past 30 days
average trading price of Landmark common stock, the exchange ratio results in an
implied  price  for  each  MNB  share  of  approximately  $9.25.   However,  the
transaction is expected to be accretive to the combined  companies' earnings per
share and to both of the companies on an individual  basis, in the first year of
operations.  The  earnings  accretion  will  result  from  pre-tax  net  revenue
opportunities  and cost  efficiencies of approximately  $1.0 million,  or 11% of
combined pro forma operating expenses. Management believes that this transaction
should  significantly  enhance the combined companies' earnings per share growth
rate.

MNB is a bank holding company headquartered in Manhattan, Kansas, which owns all
of the stock of Security National Bank, a national commercial bank. Security has
offices located in Manhattan,  Topeka, Osage City, Auburn and Wamego, Kansas. At
March 31, 2001, MNB had total assets and  stockholders'  equity of approximately
$155 million and $15 million, respectively.
