(1)      In addition, pursuant to Rule 416(c) under the Securities Act of 1933,
         this registration statement also covers an indeterminate amount of
         interests to be offered or sold pursuant to the employee benefit
         plan(s) described herein. This amendment solely increases the amount of
         registered shares from 231,000 to 662,000 shares.

(2)      Based upon last reported sale price on the over-the-counter-market, as
         quoted on NASDAQ on August 29, 1997.

(3)      The price is estimated in accordance with Rule 457(h)(1) under the
         Securities Act of 1933, as amended, solely for the purpose of
         calculating the registration fee and is the product resulting from
         multiplying 431,000, the number of additional shares registered by this
         Amendment No. 1 to the Registration Statement by $7.00 per share, the
         average exercise price of such options.
