December 1, 2000 Page 1 EXHIBIT 4(b) BRITTON & KOONTZ CAPITAL CORPORATION 500 Main Street Natchez, Mississippi 39120 December 1, 2000 [name] [address] Re: Status of options granted under the Louisiana Bancshares, Inc Incentive Stock Option Plan Dear [name]: This letter is to confirm that as of December 1, 2000, Britton & Koontz Capital Corporation ("Britton & Koontz") has assumed the incentive stock options granted to you under the Louisiana Bancshares, Inc. Incentive Stock Option Plan (the "Louisiana Bancshares Plan"). In addition, the shares of Britton & Koontz Stock (as defined below) issuable upon exercise of your options have been registered this date with the Securities and Exchange Commission in a Registration Statement on Form S-8. Your options were converted into the right to acquire shares of $2.50 par value common stock issued by Britton & Koontz ("Britton & Koontz Stock") and are exercisable in accordance with the same terms and conditions as those imposed under the Louisiana Bancshares Plan. Under the terms of the Louisiana Bancshares Plan, your options are immediately exercisable in the amounts and at the option prices set forth below: Options to Acquire Type of Option Britton & Koontz Stock Option Price ISO _____ ______ These options expire as of the earlier of three months after your termination of employment from Britton & Koontz or ten years from the original date of grant. You may exercise your options by delivering written notice of the number of options exercised and the aggregate exercise price to W. Page Ogden, Britton & Koontz Capital Corporation, 500 Main Street, Natchez, Mississippi, 39120. Enclosed is a form of Notice of Exercise that can be used for this purpose. You may pay the exercise price either in cash, in December 1, 2000 Page 2 previously acquired shares of Britton & Koontz Stock having a fair market value equal to the exercise price or a combination thereof. For this purpose, the fair market value of Britton & Koontz common stock is determined as (i) the reported closing or last sale price of Britton & Koontz common stock as reported on the Over-the-Counter Bulletin Board or other exchange on which Britton & Koontz common stock is traded on the trading day on which your options are exercised; if Britton & Koontz common stock was not traded on such date, on the next preceding day on which Britton & Koontz common stock was traded, or (ii) any other definition as determined by Britton & Koontz's board of directors. As you are aware, special tax rules apply to the exercise of incentive stock options. While your options may be exercised by tendering shares of Britton & Koontz Stock in consideration of the exercise price, the tender of securities may result in the conversion of your incentive stock options to non-qualified (or compensatory) options, in which case the exercise will be subject to tax, and you will be subject to withholding. The issuance of shares of Britton & Koontz common stock may be postponed until your withholding obligation has been satisfied. Please consult your tax advisor concerning the consequences of a tender of shares. The merger of Louisiana Bancshares and Britton & Koontz will be accounted for as a pooling-of-interests. Accordingly, you have agreed not to sell the shares received upon exercise of your options until you are notified of the publication of the results of at least 30 days of combined operations. It is currently anticipated that publication will be made on or about March 31, 2001. Also enclosed is a copy of a prospectus, which describes the options and the manner in which the Louisiana Bancshares Plan has been assumed and will be administered by Britton & Koontz. Please carefully review the prospectus before exercising your options. If you have any questions, please contact me at (601) 445-5576. Very truly yours, W.
