Attn:  Stephen M. Fisher

Dear Sirs:

     We are parties to two recently executed agreements with respect to our
performing certain investment banking services on behalf of Nova Technologies,
Inc. ("Nova") the agreement dated April 19, 1996 engaging TimeCapital Securities
Corporation ("TimeCapital") as Nova's exclusive, private placement agent (the
"Placement Agreement") and the agreement engaging TimeCapital as Nova's
exclusive agent to arrange for an underwriter (the "Underwriter Agreement").
Both the Placement Agreement and the Underwriter Agreement were amended by
executed agreements dated April 26, 1996 (the "April Amendment") and dated May
21, 1996 (the "May Amendment"), respectively.  All of the foregoing are referred
to herein collectively as the "Agreements."

     The Agreements contemplated the completion of a private placement of
500,000 shares of Nova's Common Stock at $2.00 per share and provided Nova with
certain rights if such event did not occur within the agreed time.  We hereby
agree that the Agreements be and hereby are further amended (i) to further
extend the initial period in which TimeCapital shall have the exclusive right to
effect a private placement of Nova's Capital Stock from June 30, 1996 to and
including July 19, 1996 and (ii) to provide that the proposed transaction may be
modified to such number of shares of Nova Common Stock at such price as the
parties shall agree that shall result in gross proceeds of $1,000,000.

 
     Please confirm the foregoing amendments by executing the counterpart of
this letter and returning it to TimeCapital.

Very truly yours,

ACCEPTED AND AGREED TO:
