Item 9. Undertakings.

(a) The undersigned Registrant hereby undertakes:

(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this Registration Statement;

(i) To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933;

(ii) To reflect in the prospectus any facts or events arising after the effective date of this Registration Statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in this Registration Statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high and of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20 percent change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective Registration Statement;

To include any material information with respect to the plan of distribution not previously disclosed in this Registration Statement or any material change to such information in this Registration Statement; provided,

3

however, that the undertakings set forth in paragraphs (a)(1)(i) and (a)(1)(ii) above do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed with or furnished to the Commission by the Registrant pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934 that are incorporated by reference in this Registration Statement;

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

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

(b) The undersigned Registrant hereby undertakes that, for purposes of determining any liability under the Securities Act of 1933, each filing of the Registrant's annual report pursuant to Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in this Registration Statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(c) The undersigned Registrant hereby undertakes to deliver or cause to be delivered with the prospectus, to each person to whom the prospectus is sent or given, the latest annual report, to security holders that is incorporated by reference in the prospectus and furnished pursuant to and meeting the requirements of Rule 14a-3 or Rule 14c-3 under the Securities Exchange Act of 1934; and, where interim financial information required to be presented by Article 3 of Regulation S-X is not set forth in the prospectus, to deliver, or cause to be delivered to each person to whom the prospectus is sent or given, the latest quarterly report that is specifically incorporated by reference in the prospectus to provide such interim financial information.

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

1. Purpose of the Plan. The Plan shall be known as the Guaranty Federal Bancshares, Inc. ("Corporation") 1998 Stock Option Plan (the "Plan"). The purpose of the Plan is to attract and retain qualified personnel for positions of substantial responsibility and to provide additional incentive to officers, directors, key employees and other persons providing services to the Corporation, or any present or future parent or subsidiary of the Corporation to promote the success of the business. The Plan is intended to provide for the grant of "Incentive Stock Options," within the meaning of Section 422 of the Internal Revenue Code of 1986, as amended (the "Code") and Non-Incentive Stock Options, options that do not so qualify. The provisions of the Plan relating to Incentive Stock Options shall be interpreted to conform to the requirements of
Section 422 of the Code.

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. [doublesection]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.

Such Shares may either be from authorized but unissued shares, treasury shares or shares purchased in the market for Plan purposes. If an Award shall expire, become unexercisable, or be forfeited for any reason prior to its exercise, new Awards may be granted under the Plan with respect to the number of Shares as to which such expiration has occurred.

4. Six Month Holding Period.

Subject to vesting requirements, if applicable, except in the event of death or disability of the Optionee, a minimum of six months must elapse between the date of the grant of

3

an Option and the date of the sale of the Common Stock received through the exercise of such Option.

5. Administration of the Plan.

(a) Composition of the Committee. The Plan shall be administered by the Board of Directors of the Corporation or a Committee which shall consist of not less than two Directors of the Corporation appointed by the Board and serving at the pleasure of the Board. All persons designated as members of the Committee shall meet the requirements of a "Non-Employee Director" within the meaning of Rule 16b-3 under the Securities Exchange Act of 1934, as amended, as found at 17 CFR [sect]240.16b-3.

(b) Powers of the Committee. The Committee is authorized (but only to the extent not contrary to the express provisions of the Plan or to resolutions adopted by the Board) to interpret the Plan, to prescribe, amend and rescind rules and regulations relating to the Plan, to determine the form and content of Awards to be issued under the Plan and to make other determinations necessary or advisable for the administration of the Plan, and shall have and may exercise such other power and authority as may be delegated to it by the Board from time to time. A majority of the entire Committee shall constitute a quorum and the action of a majority of the members present at any meeting at which a quorum is present shall be deemed the action of the Committee. In no event may the Committee revoke outstanding Awards without the consent of the Participant.

The President of the Corporation and such other officers as shall be designated by the Committee are hereby authorized to execute written agreements evidencing Awards on behalf of the Corporation and to cause them to be delivered to the Participants. Such agreements shall set forth the Option exercise price, the number of shares of Common Stock subject, to such Option, the expiration date of such Options, and such other terms and restrictions applicable to such Award as are determined in accordance with the Plan or the actions of the Committee.

(c) Effect of Committee's Decision. All decisions, determinations and interpretations of the Committee shall be final and conclusive on all persons affected thereby.

6. Eligibility for Awards and Limitations.

(a) The Committee shall from time to time determine the officers, Directors, Directors Emeritus, key employees and other persons who shall be granted Awards under the Plan, the number of Awards to be granted to each such persons, and whether Awards granted to each such Participant under the Plan shall be Incentive and/or Non-Incentive Stock Options. In selecting Participants and in determining the number of Shares of Common Stock to be granted to each such Participant, the Committee may consider the nature of the prior and anticipated future services rendered by each such Participant, each such Participant's current and potential contribution to the Corporation and such other factors as the Committee may, in its sole discretion, deem relevant. Participants who have been granted an Award may, if otherwise eligible, be granted additional Awards.

(b) The aggregate Fair Market Value (determined as of the date the Option is granted) of the Shares with respect to which Incentive Stock Options are exercisable for the first

4

time by each Employee during any calendar year (under all Incentive Stock Option plans, as defined in Section 422 of the Code, of the Corporation or any present or future Parent or Subsidiary of the Corporation) shall not exceed $100,000. Notwithstanding the prior provisions of this Section 6, the Committee may grant Options in excess of the foregoing limitations, provided said Options shall be clearly and specifically designated as not being Incentive Stock Options.

(c) In no event shall Shares subject to Options granted to non-employee Directors in the aggregate under this Plan exceed more than 30% of the total number of Shares authorized for delivery under this Plan pursuant to Section 3 herein or more than 5% to any individual non-employee Director, unless the Company shall receive a letter of approval or non-objection from the Office of Thrift Supervision approving the award of up to 5% to any individual non-employee Director. In no event shall Shares subject to Options granted to any Employee exceed more than 25% of the total number of Shares authorized for delivery under the Plan.

7. Term of the Plan. The Plan shall continue in effect for a term of ten (10) years from the Effective Date, unless sooner terminated pursuant to
Section 18 hereof. No Option shall be granted under the Plan after ten (10) years from the Effective Date.

8. Terms and Conditions of Incentive Stock Options. Incentive Stock Options may be granted only to Participants who are Employees. Each Incentive Stock Option granted pursuant to the Plan shall be evidenced by an instrument in such form as the Committee shall from time to time approve. Each Incentive Stock Option granted pursuant to the Plan shall comply with, and be subject to, the following terms and conditions:

(a) Option Price.

(i) The price per Share at which each Incentive Stock Option granted by the Committee under the Plan may be exercised shall not, as to any particular Incentive Stock Option, be less than the Fair Market Value of the Common Stock on the date that such Incentive Stock Option is granted.

(ii) In the case of an Employee who owns Common Stock representing more than ten percent (10%) of the outstanding Common Stock at the time the Incentive Stock Option is granted, the Incentive Stock Option exercise price shall not be less than one hundred and ten percent (110%) of the Fair Market Value of the Common Stock on the date that the Incentive Stock Option is granted.

(b) Payment. Full payment for each Share of Common Stock purchased upon the exercise of any Incentive Stock Option granted under the Plan shall be made at the time of exercise of each such Incentive 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 the Fair 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

5

payment has been received by the Corporation, and no Optionee shall have any of the rights of a stockholder of the Corporation until Shares of Common Stock are issued to the Optionee.

(c) Term of Incentive Stock Option. The term of exercisability of each Incentive Stock Option granted pursuant to the Plan shall be not more than ten (10) years from the date each such Incentive Stock Option is granted, provided that in the case of an Employee who owns stock representing more than ten percent (10%) of the Common Stock outstanding at the time the Incentive Stock Option is granted, the term of exercisability of the Incentive Stock Option shall not exceed five (5) years.

(d) Exercise Generally. Except as otherwise provided in Section 10 hereof, no Incentive Stock Option may be exercised unless the Optionee shall have been in the employ of the Corporation at all times during the period beginning with the date of grant of any such Incentive Stock Option and ending on the date three (3) months prior to the date of exercise of any such Incentive Stock Option. The Committee may impose additional conditions upon the right of an Optionee to exercise any Incentive Stock Option granted hereunder which are not inconsistent with the terms of the Plan or the requirements for qualification as an Incentive Stock Option. Except as otherwise provided by the terms of the Plan or by action of the Committee at the time of the grant of the Options, the Options will be first exercisable at the rate of 20% on the one year anniversary of the date of grant and 20% annually thereafter during such periods of service as an Employee, Director or Director Emeritus.

(e) Cashless Exercise. Subject to vesting requirements, if applicable, an Optionee who has held an Incentive Stock Option for at least six months may engage in the "cashless exercise" of the Option. Upon a cashless exercise, an Optionee 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 exercise price and any applicable withholding taxes. If the Optionee does not sell the Optioned Stock through a registered broker-dealer or equivalent third party, the Optionee 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 exercise price plus any applicable withholding taxes to the Corporation.

(f) Transferability. An Incentive Stock Option granted pursuant to the Plan shall be exercised during an Optionee's lifetime only by the Optionee to whom it was granted and shall not be assignable or transferable otherwise than by will or by the laws of descent and distribution.

9. Terms and Conditions of Non-Incentive Stock Options. Each Non-Incentive Stock Option granted pursuant to the Plan shall be evidenced by an instrument in such form as the Committee shall from time to time approve. Each Non-Incentive Stock Option granted pursuant to the Plan shall comply with and be subject to the following terms and conditions.

(a) Options Granted to Directors. Subject to the limitations of
Section 6(c), Non-Incentive Stock Options to purchase 21,704 shares of Common Stock will be granted to each Director who is not an Employee as of the Effective Date, at an exercise price equal to the Fair Market Value of the Common Stock on such date of grant. The Options will be first

6

exercisable at the rate of 20% on the one year anniversary of the Effective Date and 20% annually thereafter during such periods of service as a Director or Director Emeritus. Upon the death or Disability of the Director or Director Emeritus, such Option shall be deemed immediately 100% exercisable. Such Options shall continue to be exercisable for a period of ten years following the date of grant without regard to the continued services of such Director as a Director or Director Emeritus. In the event of the Optionee's death, such Options may be exercised by the personal representative of his estate or person or persons to whom his rights under such Option shall have passed by will or by the laws of descent and distribution. Options may be granted to newly appointed or elected non-employee Directors within the sole discretion of the Committee. The exercise price per Share of such Options granted shall be equal to the Fair Market Value of the Common Stock at the time such Options are granted. All outstanding Awards shall become immediately exercisable in the event of a Change in Control of the Savings Bank or the Company, provided that such accelerated vesting is not inconsistent with applicable regulations of the Office of Thrift Supervision or other appropriate banking regulatory agency at the time of such Change in Control. Unless otherwise inapplicable, or inconsistent with the provisions of this paragraph, the Options to be granted to Directors hereunder shall be subject to all other provisions of this Plan.

(b) Option Price. The exercise price per Share of Common Stock for each Non-Incentive Stock Option granted pursuant to the Plan shall be at such price as the Committee may determine in its sole discretion, but in no event less than the Fair Market Value of such Common Stock on the date of grant as determined by the Committee in good faith.

(c) Payment. Full payment for each Share of Common Stock purchased upon the exercise of any Non-Incentive Stock Option granted under the Plan shall be made at the time of exercise of each such Non-Incentive 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 Market Value at the date of exercise. The Company 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 has been received by the Company and no Optionee shall have any of the rights of a stockholder of the Company until the Shares of Common Stock are issued to the Optionee.

(d) Term. The term of exercisability of each Non-Incentive Stock Option granted pursuant to the Plan shall be not more than ten (10) years from the date each such Non-Incentive Stock Option is granted.

(e) Exercise Generally. The Committee may impose additional conditions upon the right of any Participant to exercise any Non-Incentive Stock Option granted hereunder which is not inconsistent with the terms of the Plan. Except as otherwise provided by the terms of the Plan or by action of the Committee at the time of the grant of the Options, the Options will be first exercisable at the rate of 20% on the one year anniversary of the date of grant and 20% annually thereafter during such periods of service as an Employee, Director or Director Emeritus.

(f) Cashless Exercise. Subject to vesting requirements, if applicable, an Optionee who has held a Non-Incentive Stock Option for at least six months may engage in the

7

"cashless exercise" of the Option. Upon a cashless exercise, an Optionee gives the Company 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 Company to pay the Option exercise price and any applicable withholding taxes. If the Optionee does not sell the Optioned Stock through a registered broker-dealer or equivalent third party, the Optionee can give the Company written notice of the exercise of the Option and the third party purchaser of the Optioned Stock shall pay the Option exercise price plus any applicable withholding taxes to the Company.

(g) Transferability. Any Non-Incentive Stock Option granted pursuant to the Plan shall be exercised during an Optionee's lifetime only by the Optionee to whom it was granted and shall not be assignable or transferable otherwise than by will or by the laws of descent and distribution.

10. Effect of Termination of Employment, Disability or Death on Incentive
Stock Options.

(a) Termination of Employment. In the event that any Optionee's employment with the Company shall terminate for any reason, other than Disability or death, all of any such Optionee's Incentive Stock Options, and all of any such Optionee's rights to purchase or receive Shares of Common Stock pursuant thereto, shall automatically terminate on (A) the earlier of (i) or
(ii): (i) the respective expiration dates of any such Incentive Stock Options, or (ii) the expiration of not more than three (3) months after the date of such termination of employment; or (B) at such later date as is determined by the Committee at the time of the grant of such Award based upon the Optionee's continuing status as a Director or Director Emeritus of the Savings Bank or the Company, but only if, and to the extent that, the Optionee was entitled to exercise any such Incentive Stock Options at the date of such termination of employment, and further that such Award shall thereafter be deemed a Non-Incentive Stock Option. In the event that a Subsidiary ceases to be a Subsidiary of the Company, the employment of all of its employees who are not immediately thereafter employees of the Company shall be deemed to terminate upon the date such Subsidiary so ceases to be a Subsidiary of the Company.

(b) Disability. In the event that any Optionee's employment with the Company shall terminate as the result of the Disability of such Optionee, such Optionee may exercise any Incentive Stock Options granted to the Optionee pursuant to the Plan at any time prior to the earlier of (i) the respective expiration dates of any such Incentive Stock Options or (ii) the date which is one (1) year after the date of such termination of employment, but only if, and to the extent that, the Optionee was entitled to exercise any such Incentive Stock Options at the date of such termination of employment.

(c) Death. In the event of the death of an Optionee, any Incentive Stock Options granted to such Optionee may be exercised by the person or persons to whom the Optionee's rights under any such Incentive Stock Options pass by will or by the laws of descent and distribution (including the Optionee's estate during the period of administration) at any time prior to the earlier of (i) the respective expiration dates of any such Incentive Stock Options or (ii) the date which is two (2) years after the date of death of such Optionee but only if, and to the

8

extent that, the Optionee was entitled to exercise any such Incentive Stock Options at the date of death. For purposes of this Section 10(c), any Incentive Stock Option held by an Optionee shall be considered exercisable at the date of his death if the only unsatisfied condition precedent to the exercisability of such Incentive Stock Option at the date of death is the passage of a specified period of time. At the discretion of the Committee, upon exercise of such Options the Optionee may receive Shares or cash or a combination thereof. If cash shall be paid in lieu of Shares, such cash shall be equal to the difference between the Fair Market Value of such Shares and the exercise price of such Options on the exercise date.

(d) Incentive Stock Options Deemed Exercisable. For purposes of Sections 10(a), 10(b) and 10(c) above, any Incentive Stock Option held by any Optionee shall be considered exercisable at the date of termination of employment if any such Incentive Stock Option would have been exercisable at such date of termination of employment without regard to the Disability or death of the Participant.

(e) Termination of Incentive Stock Options. Except as may be specified by the Committee at the time of grant of an Option, to the extent that any Incentive Stock Option granted under the Plan to any Optionee whose employment with the Company terminates shall not have been exercised within the applicable period set forth in this Section 10, any such Incentive Stock Option, and all rights to purchase or receive Shares of Common Stock pursuant thereto, as the case may be, shall terminate on the last day of the applicable period.

11. Effect of Termination of Employment, Disability or Death on
Non-Incentive Stock Options. The terms and conditions of Non-Incentive Stock Options relating to the effect of the termination of an Optionee's employment or service, Disability of an Optionee or his death shall be such terms and conditions as the Committee shall, in its sole discretion, determine at the time of termination of service, unless specifically provided for by the terms of the Agreement at the time of grant of the award.

12. Withholding Tax. The Company shall have the right to deduct from all amounts paid in cash with respect to the cashless exercise of Options 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, the Company shall have the right to require the Participant or such other person to pay the Company the amount of any taxes which the Company 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.

13. Recapitalization, Merger, Consolidation, Change in Control and
Other Transactions.

(a) Adjustment. Subject to any required action by the stockholders of the Company, within the sole discretion of the Committee, the aggregate number of Shares of Common Stock for which Options may be granted hereunder, the number of Shares of Common Stock covered by each outstanding Option, and the exercise price per Share of Common Stock of each such Option, shall all be proportionately adjusted for any increase or decrease in the number of issued and outstanding Shares of Common Stock resulting from a subdivision or consolidation

9

of Shares (whether by reason of merger, consolidation, recapitalization, reclassification, split-up, combination of shares, or otherwise) or the payment of a stock dividend (but only on the Common Stock) or any other increase or decrease in the number of such Shares of Common Stock effected without the receipt or payment of consideration by the Company (other than Shares held by dissenting stockholders).

(b) Change in Control. All outstanding Awards shall become immediately exercisable in the event of a Change in Control of the Company, as determined by the Committee, provided that such accelerated vesting is not inconsistent with applicable regulations of the Office of Thrift Supervision or other appropriate banking regulatory agency at the time of such Change in Control. In the event of such a Change in Control, the Committee and the Board of Directors will take one or more of the following actions to be effective as of the date of such Change in Control:

(i) provide that such Options shall be assumed, or equivalent options shall be substituted, ("Substitute Options") by the acquiring or succeeding corporation (or an affiliate thereof), provided that: (A) any such Substitute Options exchanged for Incentive Stock Options shall meet the requirements of Section 424(a) of the Code, and (B) the shares of stock issuable upon the exercise of such Substitute Options shall constitute securities registered in accordance with the Securities Act of 1933, as amended, ("1933 Act") or such securities shall be exempt from such registration in accordance with Sections 3(a)(2) or 3(a)(5) of the 1933 Act, (collectively, "Registered Securities"), or in the alternative, if the securities issuable upon the exercise of such Substitute Options shall not constitute Registered Securities, then the Optionee will receive upon consummation of the Change in Control transaction a cash payment for each Option surrendered equal to the difference between (1) the Fair Market Value of the consideration to be received for each share of Common Stock in the Change in Control transaction times the number of shares of Common Stock subject to such surrendered Options, and (2) the aggregate exercise price of all such surrendered Options, or

(ii) in the event of a transaction under the terms of which the holders of the Common Stock of the Company will receive upon consummation thereof a cash payment (the "Merger Price") for each share of Common Stock exchanged in the Change in Control transaction, to make or to provide for a cash payment to the Optionees equal to the difference between (A) the Merger Price times the number of shares of Common Stock subject to such Options held by each Optionee (to the extent then exercisable at prices not in excess of the Merger Price) and (B) the aggregate exercise price of all such surrendered Options in exchange for such surrendered Options.

(c) Extraordinary Corporate Action. Notwithstanding any provisions of the Plan to the contrary, subject to any required action by the stockholders of the Company, 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 Option exercise price per Share of Common Stock, and the

10

consideration to be given or received by the Company upon the exercise of any outstanding Option;

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

(iii) make such other adjustments in connection with the Plan as the Committee, in its sole discretion, deems necessary, desirable, appropriate or advisable; provided, however, that no action shall be taken by the Committee which would cause Incentive Stock Options granted pursuant to the Plan to fail to meet the requirements of Section 422 of the Code without the consent of the Optionee.

(d) Acceleration. The Committee shall at all times have the power to accelerate the exercise date of Options previously granted under the Plan; provided that such action is not contrary to regulations of the OTS or other appropriate banking regulatory agency then in effect.

Except as expressly provided in Sections 13(a) and 13(b), no Optionee shall have any rights by reason of the occurrence of any of the events described in this Section 13.

14. Time of Granting Options. The date of grant of an Option under the Plan shall, for all purposes, be the date on which the Committee makes the determination of granting such Option. Notice of the grant of an Option shall be given to each individual to whom an Option is so granted within a reasonable time after the date of such grant in a form determined by the Committee.

15. Effective Date. The Plan shall become effective upon the date of approval of the Plan by the stockholders of the Company, subject to approval or non-objection by the Office of Thrift Supervision, if applicable. The Committee may make a determination related to Awards prior to the Effective Date with such Awards to be effective upon the date of stockholder approval of the Plan.

16. Approval by Stockholders. The Plan shall be approved by stockholders of the Company within twelve (12) months before or after the date the Plan is approved by the Board.

17. Modification of Options. At any time and from time to time, the Board may authorize the Committee to direct the execution of an instrument providing for the modification of any outstanding Option, provided no such modification, extension or renewal shall confer on the holder of said Option any right or benefit which could not be conferred on the Optionee by the grant of a new Option at such time, or shall not materially decrease the Optionee's benefits under the Option without the consent of the holder of the Option, except as otherwise permitted under Section 18 hereof.

18. Amendment and Termination of the Plan.

(a) Action by the Board. The Board may alter, suspend or discontinue the Plan, except that no action of the Board may increase (other than as provided in Section 13 hereof) the maximum number of Shares permitted to be optioned under the Plan, materially

11

increase the benefits accruing to Participants under the Plan or materially modify the requirements for eligibility for participation in the Plan unless such action of the Board shall be subject to approval or ratification by the stockholders of the Company.

(b) Change in Applicable Law. Notwithstanding any other provision contained in the Plan, 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 Option unlawful or subject the Company to any penalty, the Committee may restrict any such exercise without the consent of the Optionee or other holder thereof in order to comply with any such law, rule or regulation or to avoid any such penalty.

19. Conditions Upon Issuance of Shares; Limitations on Option Exercise;
Cancellation of Option Rights.

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

(b) The inability of the Company to obtain any necessary authorizations, approvals or letters of non-objection from any regulatory body or authority deemed by the Company's counsel to be necessary to the lawful issuance and sale of any Shares issuable hereunder shall relieve the Company of any liability with respect to the non-issuance or sale of such Shares.

(c) As a condition to the exercise of an Option, the Company 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.

(d) Notwithstanding anything herein to the contrary, upon the termination of employment or service of an Optionee by the Company or its Subsidiaries for "cause" as defined at 12 C.F.R. 563.39(b)(1) as determined by the Board of Directors, all Options held by such Participant shall cease to be exercisable as of the date of such termination of employment or service.

(e) Upon the exercise of an Option by an Optionee (or the Optionee's personal representative), the Committee, in its sole and absolute discretion, may make a cash payment to the Optionee, in whole or in part, in lieu of the delivery of shares of Common Stock. Such cash payment to be paid in lieu of delivery of Common Stock shall be equal to the difference between the Fair Market Value of the Common Stock on the date of the Option exercise and the exercise price per share of the Option. Such cash payment shall be in exchange for the cancellation of such Option. Such cash payment shall not be made in the event that such transaction would result in liability to the Optionee or the Company under Section 16(b) of the Securities Exchange Act of 1934, as amended, and regulations promulgated thereunder.

12

20. Reservation of Shares. During the term of the Plan, the Company will reserve and keep available a number of Shares sufficient to satisfy the requirements of the Plan.

21. Unsecured Obligation. No Participant under the Plan shall have any interest in any fund or special asset of the Company by reason of the Plan or the grant of any Option under the Plan. No trust fund shall be created in connection with the Plan or any grant of any Option hereunder and there shall be no required funding of amounts which may become payable to any Participant.

22. No Employment Rights. No Director, Employee or other person shall have a right to be selected as a Participant under the Plan. Neither the Plan nor any action taken by the Committee in administration of the Plan shall be construed as giving any person any rights of employment or retention as an Employee, Director or in any other capacity with the Company, the Savings Bank or other Subsidiaries.

23. Governing Law. The Plan shall be governed by and construed in accordance with the laws of the State of Missouri, except to the extent that federal law shall be deemed to apply.
