                  (b)  Change  in  Control.  In the  event of such a  change  in
control or imminent change in control,  the Participant shall, at the discretion
of the  Committee,  be entitled to receive  cash in an amount  equal to the fair
market  value of the Common  Stock  subject to any Stock  Option over the Option
Price of such  Shares,  in exchange  for the  surrender  of such  Options by the
Participant on that date in the event of a change in control or imminent  change
in  control  of the  Corporation.  For  purposes  of the  Agreement,  "change in
control" shall mean: (i) the execution of an agreement for the sale of all, or a
material  portion,  of the assets of the  Corporation;  (ii) the execution of an
agreement for a merger or  recapitalization  of the Corporation or any merger or
recapitalization  whereby the Corporation is not the surviving  entity;  (iii) a
change of control of the Corporation,  as otherwise defined or determined by the
Office of  Thrift  Supervision  or  regulations  promulgated  by it; or (iv) the
acquisition,  directly or indirectly,  of the beneficial  ownership  (within the
meaning of that term as it is used in Section 13(d) of the  Securities  Exchange
Act of 1934 and the rules and regulations promulgated thereunder) of twenty-five
percent (25%) or more of the outstanding voting securities of the Corporation by
any  person,  trust,  entity or group.  This  limitation  shall not apply to the
purchase  of shares by  underwriters  in  connection  with a public  offering of
Corporation  stock,  or the  purchase  of  shares  of up to 25% of any  class of
securities of the  Corporation  by a  tax-qualified  employee stock benefit plan
which is  exempt  from the  approval  requirements,  set  forth  under 12 C.F.R.
?574.3(c)(1)(vi)  as now in  effect or as may  hereafter  be  amended.  The term
"person"  refers  to  an  individual  or  a  corporation,   partnership,  trust,
association, joint venture, pool, syndicate, sole proprietorship, unincorporated
organization  or any other form of entity not  specifically  listed herein.  For
purposes of the Agreement, "imminent change in control" shall refer to any offer
or announcement, oral or written, by any person or persons acting as a group, to
acquire control of the Corporation.  The decision of the Committee as to whether
a change  in  control  or  imminent  change in  control  has  occurred  shall be
conclusive and binding.

                  (c) Extraordinary  Corporate  Action.  Subject to any required
action by the  stockholders  of the  Corporation,  in the event of any change in
control, recapitalization,  merger, consolidation, exchange of Shares, spin-off,
reorganization,   tender  offer,   partial  or  complete  liquidation  or  other
extraordinary  corporate action or event, the Committee, in its sole discretion,
shall have the power, prior or subsequent to such action or event to:

                           (i)      appropriately adjust the number of Shares of
Common  Stock  subject to each Option,  the  exercise  price per Share of Common
Stock, and the consideration to be given or received by the Corporation upon the
exercise of any outstanding Option;

                           (ii) cancel any or all  previously  granted  Options,
provided that appropriate consideration is paid to the Participant in connection
therewith; and/or

                            (iii) make such other adjustments in connection with
the  Agreement  as the  Committee,  in its  sole  discretion,  deems  necessary,
desirable, appropriate or advisable.

         7.       Related Matters.

                  (a)  Payment.  Full  payment  for each  Share of Common  Stock
purchased  upon the exercise of any Stock Option granted herein shall be made at
the time of  exercise  of each such  Stock  Option and shall be paid in cash (in
United States Dollars),  Common Stock or a combination of cash and Common Stock.
Common Stock utilized in full or partial  payment of the exercise price shall be
valued at its fair

                                      A-4
<PAGE>

market  value at the date of  exercise.  The  Corporation  shall  accept full or
partial payment in Common Stock only to the extent  permitted by applicable law.
No Shares of Common Stock shall be issued  until full payment  therefor has been
received by the Corporation,  and no Participant shall have any of the rights of
a stockholder of the Corporation until Shares of Common Stock are issued to him.

                  (b)  Cashless  Exercise.  A  Participant  who has held a Stock
Option  for at least six months may  engage in the  "cashless  exercise"  of the
Option.  In a cashless  exercise,  a Participant  gives the Corporation  written
notice of the  exercise  of the Option  together  with an order to a  registered
broker-dealer  or  equivalent  third party,  to sell part or all of the Optioned
Stock and to deliver enough of the proceeds to the Corporation to pay the Option
price and any applicable withholding taxes. If the Participant does not sell the
Optioned Stock through a registered  broker-dealer or equivalent third party, he
can give the  Corporation  written  notice of the exercise of the Option and the
third party  purchaser of the Optioned Stock shall pay the Option price plus any
applicable withholding taxes to the Corporation.

                  (c) Transferability.  Any Stock Option granted pursuant to the
Agreement  shall  be  exercised  during  a  Participant's  lifetime  only by the
Participant  to whom it was granted and shall not be assignable or  transferable
otherwise than by will or by the laws of descent and distribution.

                  (d) Effect of Termination  of Employment or Service.  Upon the
termination of an  Participant's  employment or service with the  Corporation or
the Bank as a Director,  Director  Emeritus or  Employee,  the  Participant  may
continue to exercise  such  Options for a period  of__________________  from the
date of termination of employment or service by the  Participant,  but not later
than the date on which the Option  would  otherwise  expire.  Such  Options of a
deceased  Participant may be exercised  within two years from the date of his or
her  death,  but not later  than the date on which the  Option  would  otherwise
expire.

                  (e)  Change  in  Applicable  Law.  Notwithstanding  any  other
provision contained in the Agreement, in the event of a change in any federal or
state law,  rule or  regulation  which would make the exercise of all or part of
any previously  granted Stock Option  unlawful or subject the Corporation to any
penalty, the Committee may restrict any such exercise without the consent of the
Participant  or other holder  thereof in order to comply with any such law, rule
or regulation or to avoid any such penalty.

                  (f)  Conditions  Upon Issuance of Shares.  Shares shall not be
issued  with  respect  to any  Option  granted  under the  Agreement  unless the
issuance and  delivery of such Shares shall comply with all relevant  provisions
of law, including,  without limitation,  the Securities Act of 1933, as amended,
the  rules  and  regulations  promulgated   thereunder,   any  applicable  state
securities law and the  requirements of any stock exchange upon which the Shares
may then be listed.

         The inability of the  Corporation to obtain from any regulatory body or
authority  deemed by the  Corporation's  counsel to be  necessary  to the lawful
issuance and sale of any Shares  hereunder  shall relieve the Corporation of any
liability in respect of the non-issuance or sale of such Shares.

         As a  condition  to the  exercise  of an Option,  the  Corporation  may
require  the  person  exercising  the  Option to make such  representations  and
warranties as may be necessary to assure the  availability  of an exemption from
the registration requirements of federal or state securities law.

                  (g) Withholding  Tax. The Corporation  shall have the right to
deduct from all amounts paid in cash with  respect to the  cashless  exercise of
Options  under the  Agreement  any taxes  required  by law to be  withheld  with
respect to such cash  payments.  Where a Participant or other person is entitled
to  receive  Shares  pursuant  to the  exercise  of an  Option  pursuant  to the
Agreement,  the  Corporation  shall have the right to require the Participant or
such  other  person to pay the  Corporation  the  amount of any taxes  which the
Corporation  is required to withhold  with respect to such  Shares,  or, in lieu
thereof,  to  retain,  or to sell  without  notice,  a  number  of  such  Shares
sufficient to cover the amount required to be withheld.

                  (h)  Governing  Law.  The  Agreement  shall be governed by and
construed  in  accordance  with the laws of the State of  Kansas,  except to the
extent that federal law shall be deemed to apply.

interpretations  of the Committee  shall be final and  conclusive on all persons
affected thereby.

and be binding upon any corporate or other successor of the Bank or Parent which
shall acquire,  directly or indirectly,  by merger,  consolidation,  purchase or
otherwise,  all or  substantially  all of the  assets  or  stock  of the Bank or
Parent.

         9.  Amendments.  No amendments or additions to this Agreement  shall be
binding  upon the  parties  hereto  unless  made in  writing  and signed by both
parties, except as herein otherwise specifically provided.

         10.  Severability.  The  provisions of this  Agreement  shall be deemed
severable and the  invalidity  or  unenforceability  of any provision  shall not
affect the validity or enforceablitiy of the other provisions hereof.

         11. Entire Agreement. This Agreement together with any understanding or
modifications  thereof as agreed to in writing by the parties,  shall constitute
the entire agreement between the parties hereto.
