         NOW THEREFORE,  in consideration of the mutual  covenants,  agreements,
representations and warranties  contained herein and for other good and valuable
consideration, the receipt and sufficiency of which are hereby acknowledged, the
parties hereby covenant and agree as follows:

         1. Capitalized Terms. Unless otherwise defined,  capitalized terms used

Merger Agreement.

         2.  Appointment.  The Monterey  Shareholders  hereby appoint HPX as the
escrow agent 
                                       1

accept such appointment.

         3. Resignation and Substitution.  HPX may resign as escrow agent at any
time  by  giving  notice  of  such  resignation  to  the  Monterey  Shareholders
specifying a date when such resignation  shall take effect;  provided,  however,

Monterey Shareholders.

         4. Deposit of Warrant Stock. The Monterey  Shareholders  hereby deliver
the Warrant  Stock to HPX to be held in escrow for the  benefit of the  Monterey

which shall be reasonably acceptable to HPX.

         5. Exercise or Expiration of Warrants.

                  a. Upon the  exercise,  in whole or in part, of a Warrant by a

         Warrant  exercised;  (ii)  issue  and  deliver  a number  of  shares of
         Contingent  Warrant Stock allocable to the  Warrantholder on a pro rata
         basis  to  the  Warrant  exercised;  and  (iii)  pay  to  the  Monterey
         Shareholders an amount in cash equal to the aggregate price paid by the

         shares of  Contingent  Stock shall be issued to a Monterey  Shareholder
         only if such  Monterey  Shareholder  (i) is employed by HPX at the date

breach hereof,  whether contractual or  non-contractual,  shall be determined by
arbitration  and shall be  settled  by three  arbitrators,  one of whom shall be
appointed by HPX, one by the Monterey  Shareholders  and the third of whom shall
be appointed by the first two  arbitrators.  Persons  eligible to be selected as
arbitrators  shall be limited to attorneys who have been in practice at least 15
years  specializing  in corporate and  securities  laws matters and who have had
both training and  experience as  arbitrators  ("Experienced  Arbitrators").  If
either party fails to appoint an arbitrator within ten (10) days of a request in
writing by the other such person to do so or if the first two arbitrators cannot
agree on the  appointment of a third  arbitrator  within thirty days,  then such
arbitrator  shall be appointed by the American  Arbitration  Association  (which
appointment  shall not be limited to Experienced  Arbitrators if not made within
the applicable  time period).  Except as to the selection of  arbitrators  which
shall be as set forth above,  the  arbitration  shall be conducted  promptly and
expeditiously  as such place in Phoenix,  Arizona  agreed to between HPX and the
Monterey  Shareholders in accordance with the Commercial Rules of Arbitration of
the  American  Arbitration  Association  then  in  effect  so as to  enable  the
arbitrators  to resolve the disputes,  claims and other  matters in  controversy
within forty-five (45) days of the commencement of the arbitration  proceedings.
The arbitrators shall base their award on applicable law and judicial  precedent
and,  unless  both  parties  agree  otherwise,  shall  include in such award the
findings  of fact and  conclusions  of law upon which the award is based and may
award temporary or permanent equitable relief. Judgment on the award rendered by
the arbitrators  may be entered in any court having  jurisdiction  thereof.  The
arbitrators'   resolution   of  the   dispute   shall  be  final,   binding  and
non-appealable.   The  nonprevailing  party  shall  bear  the  expenses  of  the
arbitrators and the arbitration, including reasonable attorneys' fees and costs.
