                                 PROMISSORY NOTE


$60,000.00                                                        APRIL 17, 1997

         FOR VALUE RECEIVED, the undersigned, ESMOND T. GOEI ("Maker") hereby
promises to pay to the order of NHANCEMENT TECHNOLOGIES INC., a Delaware
corporation ("Holder") at its offices located at 39899 Balentine Drive, Newark,
California 94560, or at such place as the Holder may from time to time designate
in writing, the principal sum of SIXTY THOUSAND DOLLARS ($60,000), and to pay
simple interest on the unpaid balance of said principal from the date hereof
through maturity at the rate of seven percent (7%) per annum.

         1.    Maturity.

              (a) Principal and accrued interest under this Note shall be due
and payable at the close of business on April 17, 1998 (the "Maturity Date")

              (b) Principal and interest payments hereunder shall be made in
money of the United States of America, lawful at such times for the satisfaction
of public and private debts.

         2.    Prepayment. Maker may prepay this note in whole at any time, or
in part form time to time, without penalty or premium. Each partial prepayment
shall first be applied to interest through the date of prepayment and then to
principal.                                                                    

         3.    Default.

              (a) The failure of Maker to pay all outstanding principal and
accrued interest under this Note on or before the Maturity Date shall constitute
a default hereunder.

              (b) In the event of default, the Holder may by written notice to
Maker declare the Note to be immediately due and payable, and Holder shall then
have, in addition to all other rights and remedies, the rights and remedies of a
secured party under the U.C.C. in effect in California at that time. All such
remedies shall be exercised in such manner as not to result in a violation of
applicable federal and state securities laws.

         4.   Waiver of Demand, Protest, etc. Maker hereby waives diligence,
presentment, demand, protest and notice of any kind whatsoever. Maker promises
to pay costs of collection and reasonable attorneys' fees if default is made in
the payment of this Note. The right to plead any and all statutes of limitation
as a defense to this Note or to any agreement to pay the same, is hereby
expressly waived by the undersigned to the full extent permitted by law.
