Exhibit 16.1 June 23, 1998 Pyrocap International Corporation 15010 Farm Creek Drive, Suite 102 Woodbridge, VA 22191 Re: Form 8-K - Change of Auditors Ladies and Gentlemen: This letter is to set forth our concurrence with the information contained in Item 4 of Form 8-K, dated June 22, 1998, regarding the circumstances of our dismissal as the independent auditors for Pyrocap International Corporation ("Pyrocap"). It was mutually agreed that, due to Friedman & Fuller's new relationship with American Express Tax and Business Services, it would no longer be appropriate for Friedman & Fuller to continue as the independent auditors for Pyrocap. There were no disagreements with regard to accounting principles, financial reporting, or any other matter. Very truly yours, FRIEDMAN & FULLER, P.C. /s/ G. Stephen Fuller _______________________ G.
