     Re: 8,835 Shares of Series B Preferred  Stock of  Envirometrics,  Inc. (the
"Company") Held By Walter H. Elliott, III

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.

I am enclosing  herewith any  Certificate(s)  I 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 me.

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

I represent that I have familiarized myself with the affairs of the Company, and
I am 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 I have had sufficient opportunity to
have the  Catapult  Agreement  reviewed  by  counsel of my choice and I am fully
familiar with the terms thereof.

Sincerely yours,



Walter H. Elliott, III
