     Re: 65,875 Shares of Series B Preferred Stock of  Envirometrics,  Inc. (the
"Company") Held By S. Richard Averette

Ladies and Gentlemen:

Pursuant to our Agreement of June 30, 1998, (the  "Agreement,"  Paragraphs 10-24
of which are fully incorporated  herein by reference and ratified and reaffirmed
in their  entirety by the  undersigned),  we hereby  notify you of our intent to
convert the  above-referenced  shares of Preferred Stock (the "Preferred Stock")
to  Envirometrics  Common Stock (the  "Common  Stock") at a ratio of 5 shares of
Common Stock for one share of Preferred Stock.  Kindly effect this conversion on
the tenth day  following  your receipt of this notice or as soon  thereafter  as
practicable.

We are enclosing  herewith any Certificate(s) we hold representing the Preferred
Stock. If you are holding any  Certificate(s)  representing the Preferred Stock,
you are hereby  instructed  to cancel same upon the issuance of the Common Stock
to us.

With regard to any dividends which have accrued on the Preferred  Stock, you are
hereby  instructed  to issue  Common  Stock to us in lieu of such  accruals at a
price of $0.40 per  share.  We  understand  that no  fractional  shares  will be
issued, and shares will be rounded off to the nearest whole number.

We  represent  that we have  familiarized  ourselves  with  the  affairs  of the
Company,  and we are  aware of the  Agreement  for the  Exchange  of Stock  (the
"Catapult  Agreement")  between  the  Company and The  Catapult  Group,  Inc. of
Atlanta,  GA and that the Company  intends to effect a split of the Common Stock
prior to the Closing  thereof at a ratio of one new share of Common  Stock being
issued for every ten shares then  outstanding;  and,  further,  that we have had
sufficient opportunity to have the Catapult Agreement reviewed by counsel of our
choice and are fully familiar with the terms thereof.

Sincerely yours,
