ITEM 5.           OTHER EVENTS.

         Tech Laboratories, Inc. (the "Company") issued a press release on
August 2, 2002, announcing that an Event of Default occurred under its
outstanding 6.5% convertible promissory notes. As of July 31, 2002, the
outstanding principal and interest under the notes was $1,221,611. The Event of
Default occurred due to the fact that the waiver the Company had been granted by
the noteholders waiving any event of default under the notes, including the
requirement to have declared effective on or before June 29, 2002, the
registration statement covering the shares underlying the notes had expired
without the Company and the noteholders having reached a new agreement.
