Mr. Jim Hertzog

Dear Jim:

I am pleased to offer you the position of Controller at HiEnergy Technologies,
Inc. ("the Company"). Your role will be essentially the same with the Company as
it has been with you as a consultant to the Company. You will help the Company
with accounting and finance issues and SEC reporting.

Below are terms which I can offer to you:

     1.   Your employment will begin 07-26-04.

     2.   HiEnergy agrees to pay any legal costs you may incur in connection
          with your work for HiEnergy.

     3.   HiEnergy agrees to indemnify you against any judgments not covered by
          the Company's D & O policy.

     4.   HiEnergy agrees to keep D & O coverage in force at all times with the
          present policy limits and for the three years following termination of
          my services on a commercially reasonable effort.

     5.   HiEnergy agrees to pay you $60.00 per hour for work performed
          beginning 07-26-04.

     6.   Hi Energy agrees to issue you 100,000 warrants with a five year term
          at the closing price on 07-26-04 which vest immediately and will be
          part of the next registration statement.

     7.   HiEnergy agrees to reimburse your health and dental insurance on a
          monthly basis which is presently $311 per month.

     8.   HiEnergy agrees to reimburse you for reasonable out of pocket expenses
          for your home office.

     9.   HiEnergy agrees that you may continue to do most of your work from
          home. You agree to come to Irvine on an as needed basis.

     10.  You will agree to continue to in the same role with HiEnergy as you
          have in the past as a non-employee taking direction from me and Greg
          Henkel.

If these terms are agreeable to you, please sign below and I will arrange to
have an indemnification agreement drafted by the Company's counsel.
