ITEM 3. SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION.

Prior to February 11, 1992, the Reporting Persons beneficially owned
an aggregate of 132,757 shares of Common Stock.

On February 11, 1992, the Company issued Mr. Segasture ten year options

issuable in three equal increments on a yearly basis, of which Mr. Segasture
exercised 8,000 options on March 1, 1993 and 4,000 options on October 3, 2001.

Upon the Company's adoption of its 1992 Stock Option Plan (the "Plan"), on
the first business day of March, in each of 1993, 1994, 1995 and 1996, the
Company granted Mr. Segasture options to purchase 3,000 shares of Common

All such options granted under the Plan were immediately exercisable, except
for 834 shares under the options granted on December 31, 2000, which became
available and exercisable on July 1, 2001.

Mr. Segasture acquired, on October 3, 2001, 28,000 shares of Common Stock
upon the exercise of all the Plan options, other than the options granted
in December 2001.
