Our copy under item # 3 is missing the word NOT the second sentence, after
                                            ---
Contractor shall ______.

Our copy of item # 12 has a misspelling of the word duly, ours say's dul.

We would like to incorporate this verbiage under section 1, after the
$5.00/share.)

We would like this included (During the period from April 3, 2000 and the
expected date of funding on or about August 1, 2000 ) the fee for services shall
be $1,500.00 per month, 50% cash and 50 AMS private stock @ $5.00/share. It is
also agreed that the fee of $5,000.00 per month is subject to AMS obtaining the
necessary lending to continue this project as outlined in attached Tetrachem
Outline of services.

Please review the above statement for consideration and make your comments.

Thanks
