         the Company shall continue to pay to Executive his/her base salary and
         shall continue to provide health insurance benefits for Executive for a

         1986, as amended, or any successor provision or regulations
         promulgated.

         If this Agreement is terminated pursuant to subsection 8.01 (a), 8.01

         shall also be entitled to receive any bonus payment that as of the time
         of termination would have been payable to him/her pursuant to any
         incentive plan then in effect. "

Employees as may be selected by the Board of Directors of the Company. The
Company may also, by action of the Compensation Committee and with the express

are being granted to an Employee of that Company subsidiary) and shall be
clearly set forth in the grant of such Options. Each grant of an Option shall be

                                  OPTION PRICE

         The Option price for the Shares to be issued under the Plan shall be
determined by the Compensation Committee, but in no event shall such Option
price be less than the Fair Market Value of such Shares at the time the Option
is granted. The method for determining the Fair Market Value of the Shares shall
remain consistent with the provisions of the IRC and the regulations promulgated
thereunder, and such value shall be determined by a third party appraiser
selected by the Compensation Committee.

<PAGE>   6

         Notwithstanding the foregoing, if at the time an Option is granted to
an Employee and such Employee is an Owner-Employee (as defined herein), the
Option price at the time the Option is granted to such Employee shall be at
least one hundred ten percent (110%) of the Fair Market Value of the Shares
subject to the Option at such time, and such Option shall not be exercisable
after the expiration of the five (5) year period commencing on the date such
Option is granted.

                               DURATION OF OPTION

         In no event shall any Option granted pursuant to this Plan be
exercisable after the expiration of the ten (10) year period commencing on the
date such Option is granted (the "Option Period"). In addition, upon the
termination of a Participant's employment with the Company or any of the
Company's subsidiaries or any Affiliated Companies for any reason other than the
death, Retirement or Disability of such Participant, any and all Options held by
such Participant at the time of such termination shall lapse immediately upon
such termination. In the event a Participant's employment with the Company or
any of the Company's subsidiaries is terminated due to Retirement, any and all
Options held by such Participant at the time of such termination must be
exercised within three (3) months after such termination (but in no event more
than ten (10) years after the date such Option was granted), and otherwise such
Options shall lapse. In the event a Participant's employment with the Company or
any of the Company's subsidiaries is terminated due to death or a Participant
dies within three (3) months after termination of employment due to Retirement,
any and all Options held by such Participant at the time of his death must be
exercised within one (1) year after his death (but in no event more than ten
(10) years after the date such Option was granted), and otherwise such Options
shall lapse. In the event a Participant's employment with the Company or any of
the Company's subsidiaries is terminated due to Disability, any and all Options
held by such Participant at the time of such termination must be exercised
within one (1) year after any such termination (but

<PAGE>   7

in no event more than ten (10) years after the date such Option was granted),
and otherwise such Option shall lapse. In the event of the death of a
Participant, any and all Options held by such Participant at death may be
exercised by the personal representative of such Participant or by any
transferee permitted to receive such Options under the provisions of this Plan.

                               EXERCISE OF OPTIONS

         An Option shall be exercisable, in whole or in part, only within the
period specified in the grant of the Option, which period shall not extend
beyond the date ten (10) years after the date of the grant. In addition, no
Option granted to a Participant under this Plan shall be exercisable while there
is outstanding (as defined in IRC ss.422A(c)(7)) any other Option which was
granted to such Participant prior to the granting of such Option. A Participant
shall exercise an Option by delivering to the Company written notice which
states such intention and the number of Shares to be acquired thereby and by
making payment for such Shares to the Company at its principal office. Upon the
exercise of an Option by a Participant in compliance with the provisions of this
paragraph, and upon receipt by the Company of payment for the Shares acquired
under such Option, the Company shall deliver or cause to be delivered to such
Participant a certificate or certificates registered in the name of such
Participant for the number of Shares to be issued pursuant to the exercise of
the Option; provided, however, that in no event shall any Shares be issued
pursuant to the exercise of an Option until full payment therefor shall have
been made by cash or certified check, and the Participant shall not exercise any
rights with respect to such Shares until they have been issued. Notwithstanding
the foregoing, in lieu of payment for the Shares by cash or certified check, the
Compensation Committee may, in its absolute discretion, permit payment for the
Shares to be made by any other method it deems acceptable and which still meets
the requirements of IRC Section 422 and is in compliance with Kansas law.

<PAGE>   8

         Upon the delivery of a Share certificate pursuant to the exercise of an
Option by a Participant in compliance with the provisions hereof, a notation
shall be made on the back of the grant of Option which was exercised in whole or
in part indicating the number of Shares acquired, the date of acquisition, and
the total purchase price paid. Such notation shall be initialed by the
Participant and by the President of the Company at the closing of such sale.

                           PARTIAL EXERCISE OF OPTIONS

         Except as otherwise specifically provided herein, an Option may be
exercised in part by a Participant only upon the following conditions:

         -        Only one (1) partial exercise of an Option may be made by each
                  Participant during any calendar quarter; and

         -        Each partial exercise of any Option must result in the
                  acquisition of at least 600 Shares.

                      RESTRICTION ON DISPOSITION OF SHARES

         All options and Shares obtained through any Options shall be subject to
the Stockholders' Agreement and all dispositions of Shares (or Options) shall be
governed by the terms and conditions set forth in the Stockholders' Agreement.

                  RIGHT TO PURCHASE AFTER CERTAIN TERMINATIONS

         In the event a Participant's employment with the Company or any of the
Company's subsidiaries or any Affiliated Companies shall be terminated for any
reason other than death, Disability, or Retirement, the Company shall have the
right to purchase all or any portion of the Shares purchased by such Participant
pursuant to the exercise of an Option. Such right shall be exercised by
delivering written notice of the intention to do so to such Participant within
six (6) months after any such termination. The purchase price to be paid by the
Company for such Shares

<PAGE>   9

shall be the Fair Market Value thereof as of the date of the exercise of the
right provided for herein. The Company shall pay for such Shares in cash or by
certified check within thirty (30) days after the determination of the Fair
Market Value of such Shares, but not until the Participant has delivered to the
Company the Shares properly endorsed and free of any encumbrances.

                                   ADJUSTMENT

         In the event Enterbank declares a stock dividend, or in the event of
any reorganization, merger, consolidation, acquisition, separation,
recapitalization, stock-split, combination or exchange of Shares, or like
adjustment, the number of Shares and the class of Shares subject to any Option
granted pursuant to this Plan, and the Option price to be paid therefor, shall
be adjusted by appropriate changes in this Plan and in any Options outstanding
pursuant to this Plan. Any such adjustment to the Plan or to the Options or to
the Option prices shall be made by action of the Compensation Committee and the
determination of the Compensation Committee with respect thereto shall be
conclusive. Notwithstanding the foregoing, no adjustment shall be made to any
Option granted pursuant to this Plan which would cause such Option to cease to
qualify as an Incentive Stock Option within the meaning of IRC Section 422.

         All provisions of this Plan, including without limitation all rights
and restrictions concerning sale, transfer or other disposition of Shares shall
apply with equal force and effect to any additional Shares or different class of
shares made subject to any Option granted pursuant to this Plan, as a result of
an adjustment in accordance with the provisions hereof. Such additional Shares
or different class of shares shall be treated in all respects as Shares
originally subject to the provisions of this Plan.

                        INTENTION TO CONTINUE EMPLOYMENT

         Each Participant, as a condition to the granting to him of each Option
hereunder, shall represent to the Company that it is his present intention to
remain in the employ of the Company (or any of the Company's subsidiaries or any
Affiliated Companies), subject to the rights of the Company or any of the
Company's subsidiaries or any Affiliated Companies to terminate the employment
of such Participant at any time, for a period of at least two years after the
date of such grant or until the death, Disability, or Retirement of such
Participant prior to the expiration of such two year period.

                              LIMITATION OF RIGHTS

         No provision in this Plan shall be construed by the Company, any of the
Company's subsidiaries or any Employee in any way to:

         -        Give any Employee of the Company or any of the Company's
                  subsidiaries any right to be granted any Options other than
                  those granted to him in the sole discretion of the Board of
                  Directors;

         -        Give a Participant at any time while he is not an actual

         -        Limit in any way the right of the Company or any of the

                  time;

         -        Be evidence of any agreement or understanding, express or
                  implied, that the

                  Participant in any particular position or at any particular
                  rate of remuneration or for any particular period of time.

                        AMENDMENT OR TERMINATION OF PLAN

         The Board of Directors of the Company may terminate or amend this Plan
at any time; provided, however, that any such termination or amendment shall not
alter, amend, discontinue, revoke, or otherwise impair any outstanding Options
previously granted pursuant to this Plan which remain unexercised.

                               REQUIREMENTS OF LAW

         If any law, regulation of the Securities and Exchange Commission, or
any regulation of any other commission or agency shall require the Company or a
Participant to take any action with respect to the Shares acquired by the
exercise of an Option, the date upon which the Company shall deliver or cause to
be delivered the certificate or certificates for the Shares so acquired shall be
postponed until full compliance has been made with all such requirements of such
law or regulation. Further, at or before the time of the delivery of the Shares
acquired by the exercise of an Option, each Participant shall deliver to the
Company a written statement that he intends to hold the Shares so acquired for
investment and not with a view to resale or other distribution to the public. In
addition, in the event the Company shall determine that, in compliance with the
Securities Act of 1933 or other applicable statutes or regulations, it is
necessary to register any of the Shares or to qualify any such Shares for an
exemption from any of the requirements of said Act or any other law, the Company
shall take such action at its own expense, and not until such action has been
completed shall such Shares be delivered to the Participant exercising the
Option.
