     (1) The Buckle, Inc. (the "Company") originally filed an S-8 to register
10,000 shares of Common Stock (File No. 33-64104), issuable pursuant to its 1993
Directors Stock Option Plan (the "Plan"). Subsequent to that filing, the Company
effected a 2-for-1 stock split on April 24, 1997 which automatically increased
the shares issuable pursuant to the Plan to 20,000. On May 28, 1998, a majority
of the shareholders approved an amendment to the Plan to increase the number of
shares issuable pursuant to the Plan by 30,000. On May 28, 1998, the Company
also effected a 3-for-2 stock split. Thus, this Amendment No. 1 is filed to
register 45,000 additional shares, which number of shares equals the 30,000
shares added pursuant to shareholder amendment, adjusted to 45,000 shares
pursuant to the 3-for-2 stock split.
