Gentlemen:

Reference is made to Exhibit A, the form of 8% Convertible Debenture (the

"Purchase Agreement"), dated May 19, 2000, between NHancement Technologies Inc.,

together the "Investors"). Provision 3 of the Debenture, as currently
constituted, provides that the Holder of the Debenture is entitled, at its
option, to convert at any time commencing on the date hereof, the principal
amount of this Debenture or any portion thereof, into shares of Common Stock of

(3) lowest closing bid prices during the ten (10) Trading Days immediately
preceding the Conversion Date; PROVIDED, HOWEVER, the Conversion Price shall
not be less than $10.00 (adjusted for stock splits and the like). The Company
and the Purchaser hereby agree to revise said provisions from the Purchase
Agreement.

In consideration of the mutual covenants and agreements contained herein, and
for other good and valuable consideration, the receipt and sufficiency of which
are hereby acknowledged, the parties hereby agree to restate the following
provision of the Debenture as follows:

                  Provision 3.  The Holder of this Debenture is
         entitled, at its option, to convert at any time commencing on
         the date hereof, the principal amount of this Debenture or any
         portion thereof, into shares of Common Stock of the Company
         ("Conversion Shares") at a conversion price for each share of
         Common Stock ("Conversion Price") equal to the lesser of
         $13.00 (subject to adjustment for stock splits and the like)
         or (ii) 91% of the average of the three (3) lowest closing bid
         prices during the ten (10) Trading Days immediately preceding
         the Conversion Date; PROVIDED, HOWEVER, the Conversion Price
         shall not be less than $8.00 (adjusted for stock splits and
         the like).

Except as specifically amended by the terms of this letter, the Purchase
Agreement and the Debenture shall remain unmodified and in full force and
effect, and shall not be in any way changed, modified or superseded by the terms
set forth herein. All terms used but not defined in this letter shall have the
meanings set forth in the Purchase Agreement.

This letter may be executed in any numbers of counterparts, all of which taken
together shall constitute one and the same instrument and shall become effective
when counterparts have been signed by each party and delivered to the other
parties hereto, it being understood that all parties need not sign in the same
counterpart. Execution may be made by delivery by facsimile.
