     Term. The term of this engagement ends on December 31st, 2004.

     Compensation.  The parties acknowledge that it is their mutual expectation,
that the services to be provided by Consultant to Client hereunder,  will result
in increased revenues of Client,  increased shareholders equity of Client and/or

Client's Net Tangible Book Value as described in the paragraph below.

     Vesting  Based Upon Net Tangible Book Value  Increases.  Vesting based upon

for each  increase of $3.00 over the Net  Tangible  Book Value number as of July
31st,  2004, an Option for one share shall vest, to the maximum of $3,000,000 or
1,000,000  shares.  Any Client net operating  losses will not be included in the

Vesting  shall be  calculated  and  effective at the end of each fiscal  quarter
during the Term of the  Agreement.  The Net Tangible Book Value number ending on
July 31st,  2004 will be provided to  Consultant  by Client in writing not later
than  September  30th,  2004.  The number will be expressly  made a part of this
Agreement.

     Exercise Period.  Any of the Options granted hereunder shall be exercisable
for a period of three years from the date such Option(s) vest.

(12) months from the execution date of this Definitive Agreement.

     Confidential  Information.   Except  as  permitted  by  Client,  Consultant
covenant and agrees not to disclose,  directly or indirectly, at any time either
during the term of this  Agreement or within twenty four (24) months  subsequent
to the  termination of this  Agreement to anyone not an employee of Client,  and
not to use at any time either during the term of this Letter Agreement or within
two (2) years  thereafter,  except as permitted by Client,  any  proprietary  or
confidential  information of Client unless it shall involuntarily be required to
do so by a court having competent  jurisdiction  after notice to Client.  Client
and Consultant hereby acknowledge that: (a) the duration limitation imposed with
respect to said secret and confidential information are reasonable;  and (b) the
restrictions  stated hereinabove are reasonably  necessary for the protection of
Client's legitimate proprietary interests.

     Arbitration.  Any  controversy  or claim arising out of or relating to this
Agreement,  or the breach thereof, shall be settled by arbitration in accordance
with the Commercial  Arbitration Rules of the American  Arbitration  Association
and  judgment  on  the  award  rendered  may be  entered  in  any  court  having



jurisdiction  thereof. Such arbitration shall be held in San Diego County, State
of California, and the cost thereof, including reasonable attorneys' fees, shall
be borne  by the  losing  party or in such  proportions  as the  arbitrator  may
decide.

     Indemnification.  Client agrees to indemnify  and hold harmless  Consultant
and each  person,  who control  Consultant  against any and all losses,  claims,
damages  or  liabilities,  joint or  several,  to which  they or any of them may
become subject, and to reimburse Consultant and each such controlling person, if
any,  for any  legal  or other  expenses  reasonably  incurred  by it or them in
connection with defending any actions,  insofar as such losses, claims, damages,
liabilities  or actions  arise out of or are based upon any untrue  statement or
alleged  untrue  statement  of a  material  fact  contained  in any  information
provided by Client to Consultant to give to a Contact or provided  directly to a
Contact by  Client,  or the  omission  or alleged  omission  to state  therein a
material fact required to be stated  therein or necessary to make the statements
therein not misleading.

     Consultant  agrees to indemnify and hold  harmless  Client and each person,
who  controls  Consultant  against  any  and  all  losses,  claims,  damages  or
liabilities,  joint or several, to which they or any of them may become subject,

time by mutual written agreement of the parties.

     Severability.   The  invalidity  or   unenforceability  of  any  particular
provision  of this  Agreement  shall not affect its other  provisions,  and this
Agreement shall be construed in all respects as if such invalid or unenforceable
provision had been omitted.

     Waiver.  No  waiver by either  party of a breach of any  provision  of this
Agreement shall operate as or be construed to be a waiver of any other breach of
that provision or of any breach of any other  provision of this  Agreement.  The
failure of a party to insist upon strict adherence to any term of this Agreement
on one or more occasions  shall not be considered a waiver or deprive that party



of the right  thereafter  to insist  upon strict  adherence  to that term or any
other term of this Agreement. Any waiver must be in writing.

and  neither  party may assign  nor  delegate  any of its rights or  obligations
hereunder  without first obtaining the written consent of the other party.  Once
vested,  the options may not be assigned  by  Consultant  to any person  except,
Consultant  may  assign  one or  more  options,  or an  interest  in one or more
options,  to Troika Capital  subject to troika  Capital  agreeing not to further
assign such options or such interest in such options.
