     Re: 2,250 Shares of Series B Preferred  Stock of  Envirometrics,  Inc. (the

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: (a) 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; (b) we have  received and  reviewed a copy of the  Catapult  press
release dated March 13, 2000 which refers to the Catapult Agreement;  and (c) we
are aware that the Company  intends to effect a split of the Common  Stock prior
to the closing of the  Catapult  Agreement at a ratio of one new share of Common
Stock being issued for every ten shares then outstanding.


Sincerely yours,
