Dear Henrik:

As you are aware, the Company has agreed to hereby amend your Agreement
(previously amended effective October 27, 1996) by this letter Amendment,
effective November 1, 1997, as follows:

D.  TERM OF AGREEMENT shall be amended by deleting the first sentence thereof
and replacing it with:  "Employment hereunder shall commence on November 1, 1997
for a term of twenty four (24) months, ending October 31, 1999 ("Term"), unless
sooner terminated pursuant to Paragraph O hereof."

The remainder of Paragraph D shall be unchanged.

X.1  SALARY shall be amended in its entirety to read:  

     "a.  Effective until 10/31/97 Three Hundred Fifty Thousand Dollars
          ($350,000.00) per year (at the rate of $29,167 per month)

      b.  Effective on 11/1/97 and 11/1/98 and for each Fiscal Year of any
          Extended Term, if any, of this Agreement, the Salary set forth in
          Paragraph X.1(a) will be adjusted upward annually to reflect the

          ("ACA") Index for the Western Region ("ACA Index") with a six (6%) per
          cent maximum increase.  The adjustment, if any, shall be based upon
          the projected ACA Index as published for the effective date of the
          proposed increase hereunder.  There shall be no downward adjustment in
          Salary in the event the ACA Index shows a decrease from the prior
          Fiscal Year."

X.5  BONUS shall be added to the Agreement to read:

5.   BONUS:  Subject to proration in the event of modification or termination of
     employment hereunder, Executive shall be paid a bonus ("Bonus") based on
     the profit ("Profit") for each fiscal year, or partial fiscal year, of
     employment hereunder commencing November 1st and ending October 31st
     ("Fiscal Year") during the Term, and during the Extended Term, if any, of
     this Agreement.
          
     (a)  Such Bonus for each Fiscal Year shall be 0.2842% percent (.002842) of

          forth in Paragraph F1 herein.
               
     (d)  Executive shall have the right to obtain an advance against such Bonus
          at the end of each month of each Fiscal Year in an amount equal to
          fifty per cent (50% of, or 0.5 times) the projected amount of such
          Bonus based on the Profit at that time.
               
     (e)  Either the independent public accounting firm or the accounting
