amount of _______ shares of restricted stock issuable during the term, after
execution of this Agreement. In the event SGI files a registration statement
with the SEC within the next calendar year under which it could register the
restricted stock issued Consultant, then it shall do so, absent a determination
by its Board of Directors that such registration would cause SGI economical or
other harm.

b. Expenses. Consultant shall be reimbursed for reasonable expenses, including,
but not limited to, travel, long distance telephone charges, and mileage at
the rate of $.30 a mile for all business travel.

reasonable notice, computer programs, data, and any documentation required by
Consultant to complete the Services.

5. Term. This Agreement shall be effective on the Effective Date and shall
continue for a period of one year.

6. Warranties. Consultant hereby warrants that he will carry out his work in
accord with generally accepted practices.

7. Independent Contractor. Consultant is and at all times during the term of
this Agreement shall be an independent contractor providing professional
consulting services to SGI. Nothing contained in this Agreement shall be

Consultant shall have no power to commit or bind SGI in any manner whatsoever.

8. Limitation of Liability. In no event shall either of the parties hereto be
liable to the other for the payment of any consequential, indirect, or special
damages, including lost profits.

9. Injunctive Relief. It is hereby understood and agreed that damages are an
inadequate remedy in the event of a breach by Consultant of the Confidentiality
provisions of this Agreement and that any such breach by Consultant will cause
SGI great and irreparable injury and damage. Accordingly, Consultant agrees that
SGI shall be entitled, without waiving any additional rights or remedies
otherwise available to SGI at law or in equity or by statute, and without
posting any bond, to obtain injunctive or other equitable relief in the event of
a breach or intended or threatened breach by Consultant of such provisions.

incorporate by reference all of the terms of this Agreement. Consultant agrees
to guarantee the performance of any subcontractor used in the performance of
the Services.

11. Conflicting Assignments. During the term of this Agreement, Consultant shall
not accept conflicting assignments, which would put Consultant in a position
where he would be rendering advice or providing information to any party who
might be a potential competitor of SGI presently or in the future, nor shall
Consultant provide any advice, which might disclose any confidential
Information.

12. Disputes. If any dispute of any kind arises between the parties with respect
to the Consultant's performance under this Agreement, then the dispute shall be
submitted to arbitration in San Diego, California to the American Arbitration
Association ("AAA"). The dispute shall be submitted to an arbitrator selected
from a panel of arbitrators submitted to the parties by the AAA. If the parties

absence of such appointment, the parties may request an appointment by making an
application to the San Diego Superior Court to order an appointment. Reasonable
discovery, including but not limited to depositions and interrogatories, shall
be allowed in any such arbitration. The decision of the arbitrator shall be
binding and enforceable to the same extent as if the award were made by a court
of competent jurisdiction.

13. Notices. Any and all notices and other communications hereunder shall be in
writing and shall be deemed to have been duly given or received when delivered
personally or forty-eight (48) hours after being mailed, via first-class U. S.

matter hereof and supersedes any prior written or oral understanding or
agreement between the parties relating to the subject matter hereof. This
Agreement shall not be amended, altered, or supplemented in any way except by an
instrument in writing, signed by the duly authorized representative of the
parties, that expressly references this Agreement.

17. Waivers. The failure or delay of either party to exercise or enforce at any
time any of the provisions of this Agreement shall not constitute or be deemed a
waiver of that party's right thereafter to enforce each and every provision of
the Agreement and shall not otherwise affect the validity of this Agreement.

18. Severability. If any provision of this Agreement is finally determined to be
contrary to, prohibited by, or invalid under applicable laws or regulations,
such provision shall become inapplicable and shall be deemed omitted from this
Agreement. Such determination shall not, however, in any way invalidate the
remaining provisions of this Agreement.
