agree to engage in the following specific joint marketing  activities during the
Initial Term of this Agreement:

A. Trade Shows. The parties agree to jointly  participate in the following trade

accepted  accounting  principles fairly and consistently  applied;  and shall be

Party.  On April 1, 2001 and annually  thereafter for the balance of the Term of
this Amended Joint Marketing  Agreement or any renewal term as provided  herein,
the Party shall  reanalyze the profit  sharing  allocation.  Such  reanalyzation
shall involve an analysis of the actual  pre-tax profit of the First Party as to
the sale of the  Products.  If the actual  pre-tax  profit of the First Party is
more than 16% then the  profit  share of the First  Party and the  Second  Party
shall be reallocated to increase the percentage of the Second Party and decrease
the  percentage of the First Party to properly  reallocate  the profit earned by
party of the First  Party in excess of 16%.  If the profit of the First Party is
less than 16%, then the First Party shall have the unilateral right to terminate
this Amended Joint Marketing Agreement.

F. Royalties. In addition to any other sums earned under this Amended Agreement,
the Party of the Second  Party  shall earn a Royalty  equal to 5% of the cost of
any Products  manufactured by Tech  Laboratories,  Inc. and marketed pursuant to
this Amended Joint Marketing Agreement.
