     The Company has reserved a total of 250,000 shares for issuance under its
Incentive Stock Option Plan (the "Plan"). Options may be granted to officers,
directors, and other key Company employees. Options granted under the Plan are
intended to qualify as incentive stock options as defined in the Internal
Revenue Code of 1986, as amended.

     The plan is administered by the Board of Directors and a Stock Option
Committee presently consisting of two members of the Board that determines which
persons are to receive options, the number of options to be granted and the
exercise prices. In the event an optionee voluntarily terminates employment with
the Company, the optionee has the right to exercise his accrued options within
thirty (30) days of such termination. However, the Company may exercise any
accrued options held by each optionee by paying the difference between the
option exercise price and the then fair market value.

     All employee options issued to date under the Plan have a five-year term
and vest evenly over the first three years commencing on the date of the grant.
Director options vest over a one-year period.

     The Company has also granted nonqualified stock options for 285,366 shares
of common stock at option prices ranging from $.31 to $1.03 per share expiring
at various dates through 2004.

     There were no options granted or exercised in fiscal year 2001 or 2002.
