       The source of funds to be used to consummate the transaction discussed in Item 4 below has not been determined at this time.

Item 4. Purpose of Transaction

       Until the date hereof, the reporting persons have reported their beneficial ownership of Guaranty common stock on Schedule 13G pursuant to Rule 13d-1(c). In accordance with Rule 13d-1(e), the reporting persons are now filing this Schedule 13D, not because of an additional acquisition of common stock of Guaranty, but because Great Southern sent to Guaranty a letter dated August 13, 2001, in which Great Southern offered to negotiate a merger between Guaranty and Great Southern at a price of $16.00 per share of Guaranty's common stock (the "Letter").

       The reporting persons acquired the subject securities for investment purposes at various times between December 30, 1997 and December 7, 1999. The reporting persons believed at the time the subject securities were acquired that significant price appreciation could be achieved as Guaranty began to utilize the capital raised in its conversion to stock form.

9 of 20 next page

       Since December 7, 1999, however, the earnings, return on equity and stock performance of Guaranty have been relatively flat, despite the repurchase by Guaranty of more than 2.4 million shares of its common stock. As a result, the reporting persons do not believe that the value of Guaranty's franchise is adequately reflected in the current market price of Guaranty's common stock.  Accordingly, representatives of the reporting persons met with representatives of Guaranty on June 29, 2001 to discuss their investment in Guaranty.

       In analyzing several alternatives related to its investment in Guaranty, Great Southern considered a combination with Guaranty. The reporting persons believe that meaningful synergies can be achieved via consolidation of the data processing, legal, audit, administrative and public reporting functions. The reporting persons further believe that Guaranty's shareholders, customers and employees would benefit from such a transaction.

       Accordingly, on August 13, 2001 Great Southern followed up on its recent conversations with Guaranty with a letter authorized by Great Southern's Board of Directors. The Letter expressed a desire to negotiate a merger with Guaranty wherein Great Southern would pay Guaranty's shareholders $16.00 per share -- half in cash and half in stock.

       The reporting persons are aware that, on January 20, 1999, Guaranty adopted a shareholder protection rights plan designed to protect shareholders and Guaranty from coercive or unfair takeover tactics by a hostile acquiror seeking to gain control of Guaranty without offering a fair price to all its shareholders. The purpose of this plan, according to the letter from President Haseltine to shareholders announcing the plan, was to "discourage hostile tactics that impair the board's ability to fully represent the interests of all shareholders."

       Mr. Haseltine further stated that, "[T]he Plan is not intended, however, to prevent an acquisition proposal or an acquisition of the Company which is fair and equitable to all shareholders. It will not deter any person or group who may be interested in acquiring control of the Company, if such person is willing to negotiate with the Board of Directors and to make an offer to acquire control of the Company's stock on terms and conditions that are favorable and fair to all shareholders."

       Great Southern is also cognizant of its regulatory requirements as a federally regulated financial holding company, and the commitments it agreed to as part of obtaining approval to acquire its current ownership interest in Guaranty. As a result, Great Southern is not commencing, or announcing an intention to make, a tender offer or exchange offer, nor is it intending to cause Guaranty or any of its subsidiaries to become a subsidiary of Great Southern or any of its subsidiaries. Great Southern is merely offering to negotiate with the Board of Directors of Guaranty a transaction on terms and conditions that are favorable and fair to all shareholders.

       A copy of the Letter is attached as Exhibit 1 to the Schedule 13D. Great Southern may at any time withdraw or modify its offer to negotiate set forth in the Letter or make a new offer to negotiate.

       Subject to compliance with Guaranty's shareholder protection rights plan and federal regulatory compliance, any one or more of the reporting persons may decide to purchase additional shares of Guaranty common stock or sell shares of Guaranty common stock, although none of them has the current intention to do so. Except as set forth above, none of the reporting persons nor, to the best

knowledge of each reporting person, any of the individuals identified on Schedule I, has any present plans or proposals which relate to or would result in any of the transactions described in paragraphs (a) through (j) of Item 4 of Schedule 13D.

EXHIBIT 1

[LETTERHEAD OF GREAT SOUTHERN BANCORP, INC.]

August 13, 2001

Board of Directors
Guaranty Federal Bancshares, Inc.
1341 W. Battlefield
Springfield, MO 65807

Via hand delivery and certified mail return receipt requested

Dear Sirs:

               I am pleased to submit, on behalf of Great Southern Bancorp, Inc. ("Great Southern"), this offer to negotiate for a combination of Great Southern and Guaranty Federal Bancshares, Inc. ("Guaranty"). We believe a combination would bring great benefits for all the important constituencies served by our companies. We are extremely serious about this combination and believe that it reflects the significant strategic importance we place on Guaranty, and, accordingly, presents an exceptional value for your shareholders.

              Please note this offer to negotiate is not the commencement of, or the announcement of an intention to make, a tender offer or exchange offer, nor is this offer to negotiate intended to cause Guaranty or any of its subsidiaries to become a subsidiary of Great Southern or any of its subsidiaries.

              Subject to completion of satisfactory due diligence, amendment or redemption of Guaranty's Preferred Share Purchase Rights, so as to render them inapplicable to the merger, negotiation and execution of a definitive merger agreement and approval of the appropriate banking regulators, we propose a merger in which the shareholders of Guaranty would receive $16.00 per share, with one-half of the consideration payable in cash and the other one-half payable in Great Southern common stock. This price would represent a premium of approximately 26% over Guaranty's current stock price. The merger would be structured as a tax-free transaction at the corporate level. There would be "capital gains" tax treatment available to Guaranty's shareholders for the cash portion of the merger consideration with taxes being deferred on the stock portion. We would plan to account for the transaction as a purchase with Guaranty Federal Savings being merged into Great Southern Bank.

16 of 20 next page

              We are prepared to move immediately forward with due diligence. We believe that we could jointly conclude the negotiation and execution of a definitive agreement in an expeditious fashion and are highly confident of our ability to close this transaction quickly and efficiently, with no regulatory impediments. No approval of Great Southern shareholders would be needed to consummate this transaction.

              As stated above, we are very excited about this opportunity to combine our organizations. We believe strongly that a combination with Great Southern would generate superior short and long-term benefits for your shareholders and customers, as well as for your employees.

              Your shareholders would benefit by receiving an ownership interest in the high quality, diversified community banking franchise that would result from our partnership.Based on the FDIC's June 30, 2000 market share report (the latest available) our pro forma deposit market share would be number one in both Greene County and in Springfield, Missouri. Additionally, based on deed of trust filings through June 30, 2001, our combined real estate lending operation would be number one in Greene County.

              The proposed price is 20.5 times your last twelve months earnings, 35% of your deposits and 16% of your assets. Further, on a pro forma basis we believe the earnings per share for Guaranty's shareholders would be at least 85% greater than as a stand-alone company. In our view, all these numbers represent the superior value we perceive in this transaction and offer Guaranty's shareholders an unparalleled opportunity to enhance the value of their investment.

              Your shareholders would also receive a more liquid and actively traded stock. In the five years since June 30,1996 our stock price and earnings per share have increased by annual compounded rates of 16% and 15%, respectively. In short, we believe this transaction represents outstanding value for your shareholders.

              Your customers would benefit from an expanded offering of products and services, the most extensive banking network throughout our market as well as the pro forma strength of the combined institution. Importantly, customers would also benefit from our integration strategy, which is based on maintaining Guaranty's strong customer relationships. As outlined below, it would be our intention for customers of Guaranty to continue doing business with many of the folks they work with today in addition to our very capable staff. Additionally, Great Southern, as a community oriented institution, is committed to being involved with the community it serves, with local decision making and local community board leadership.

              Your employees would benefit from an association with a combined institution which provides greater advancement and career opportunities, competitive salaries and participation in Great Southern's numerous benefit programs including its pension, 401-k and incentive stock option plans. Critical to our strategy would be the retention of a dedicated and capable employee base with knowledge of your customers. The employees of Guaranty would be essential to our effort working with us to expand your franchise.

              We feel very positive about the prospect of a merger with Guaranty and believe it would be most beneficial for your shareholders, employees and customers. When the undersigned, along with Bill Turner and Tom Carlson met with Jim Haseltine, Jack Barham and Greg Ostergren, those members of your board assured us that the Guaranty board would, consistent with its fiduciary duty to shareholders, carefully consider a combination proposal from Great Southern or anyone else. We believe that upon completion of your analysis you will agree this offer to negotiate is in the best interest of your shareholders, customers and employees. We look forward to receiving your favorable response within the next seven days and invite you to contact me at 887-4400 if you have any questions.

Very truly yours,
