Item 1.01 Entry into a Material Definitive Agreement

     On February 2, 2007, Southwest Bancorp, Inc. (“Southwest”), and its wholly owned subsidiary, Stillwater National Bank and Trust Company (“SNB”), a national bank with its main office in Stillwater, Oklahoma, entered into an Agreement and Plan of Merger (the “agreement”) with Bank of Kansas, a commercial bank with its main office in South Hutchinson, Kansas and Hart Food Stores, Inc. (“HFS”) a Kansas corporation and parent bank holding company of Bank of Kansas. The Agreement calls for the acquisition of HFS and Bank of Kansas by merger for total cash consideration of $15.25 million.

     HFS owns approximately 85% of the outstanding common stock of Bank of Kansas. The Agreement calls for HFS to merge with a newly formed subsidiary of Southwest created for purposes of the merger. In this merger, HFS shares will be converted into the right to receive cash equal to the fair value of the HFS shareholder’s equity. In calculating the fair value, the shares of Bank of Kansas common stock owned by HFS will be valued at $610.00 per share. After the Merger, HFS will be a wholly owned subsidiary of Southwest.

     The agreement also calls for Bank of Kansas to merge with a newly formed interim bank created for purposes of the Bank merger. In the Bank merger, each share of Bank of Kansas stock not owned by HFS, other than any shares as to which dissenters’ appraisal rights have been exercised, will be converted into the right to receive $610.00 per share in cash. After the Bank Merger, Bank of Kansas will be a wholly owned subsidiary of Southwest.

     The mergers are subject to conditions, including regulatory approval; approval by shareholders owning of record at least 95% of the outstanding shares of Bank of Kansas, approval by all of the shareholders of HFS; and other, customary conditions.

     The board of directors of Bank of Kansas has determined that the merger is in the best interests of the bank and its shareholders, and that the merger consideration is fair to Bank of Kansas shareholders. All of the shareholders of HFS have executed a support agreement which provides that they will vote their shares in favor of the merger agreement and the transactions it contemplates and against any other merger or other extraordinary corporate transaction involving HFS or Bank of Kansas.

     The agreement contains customary representations, warranties and covenants, including, among others, covenants by HFS and Bank of Kansas not to (i) solicit proposals relating to any other merger or other extraordinary corporate transaction involving HFS or Bank of Kansas, or (ii) subject to certain exceptions, enter into discussions regarding, or provide material non-public information in connection with, an any other merger or other extraordinary corporate transaction involving HFS or Bank of Kansas.

     The agreement provides for termination rights of the parties under certain circumstances, and further provides that, upon termination of the agreement under specified circumstances, Bank of Kansas or any other acquiror of Bank of Kansas is required to pay to SNB a termination fee of $500,000.

     The above is intended merely as a summary of principal terms of the agreement, and is
