(the "Company") registered thereunder, which Common Stock is to be issued pursuant to an Amended Agreement of Merger and Plan of Reorganization, dated June 19, 1995, among the Company, First Robinson Bancorp, FRB Corp., The First National Bank in Robinson, and Farmers' State Bank of Palestine (the "Merger Agreement"). As counsel to the Company, we have participated in the preparation of the Registration Statement. We have examined and are familiar with the Company's Articles of Incorporation, Bylaws, as amended, records of corporate proceedings and such other information and documents as we have deemed necessary or appropriate. Based upon the foregoing, we are of the opinion that the Common Stock has been duly authorized and will, when issued as contemplated in the Registration Statement and the Merger Agreement, be validly issued, fully paid and non-assessable. We consent to the use of this opinion as an Exhibit to the Registration Statement. Very truly yours, /s/ Leagre & Barnes 0002\10\s-4\exh-5
