         E. Headwaters,  Merger Sub, HTI, and the HTI Founders wish to amend the
Merger Agreement as of this date and to specify the Closing Date for the Merger.

         NOW,  THEREFORE,  in  consideration  of the  premises and of the mutual
agreements  contained herein and in the Merger Agreement,  the Parties do hereby
agree as follows:

         1. Section 10.1(e) of the Merger Agreement is hereby amended to read in
its entirety as follows:

                  (e)      by either HTI or  Headwaters  if the Merger shall not
                           have been  consummated by August 31, 2001;  provided,
                           however,  that the right to terminate  this Agreement
                           and the Exchange Agreement under this Section 10.1(e)
                           shall not be  available  to any party whose action or
                           failure  to act  has  been a  principal  cause  of or
                           resulted  in the  failure  of the  Exchange  and  the
                           Merger  to  occur  on or  before  such  date and such
                           action or failure to act  constitutes  a willful  and
                           material  breach of this  Agreement  and the Exchange
                           Agreement;

<PAGE>

         2. In accordance with Section 1.2 of the Merger Agreement,  the Closing
of the Merger  shall take place on August 31,  2001,  or as soon  thereafter  as
practicable,  subject to the satisfaction or waiver of all closing conditions in
the Merger  Agreement  and the prior  Closing of the  Exchanges  under the Share
Exchange   Agreement  among  Headwaters,   Merger  Sub,  HTI,  and  certain  HTI
shareholders.

         IN WITNESS WHEREOF,  the Parties hereto have executed this Amendment #1
to the Merger Agreement as of the day and year first above written.
