OF ITS, HIS OR HER CHOICE, KNOWINGLY AND VOLUNTARILY, AND FOR THE MUTUAL BENEFIT
OF ALL PARTIES, WAIVES ANY RIGHT TO TRIAL BY JURY IN THE EVENT OF LITIGATION
ARISING OUT OF OR RELATED TO THIS LOAN AND SECURITY AGREEMENT OR ANY OTHER
DOCUMENT, INSTRUMENT OR AGREEMENT BETWEEN THE UNDERSIGNED PARTIES.

          12. REFERENCE PROVISION.

               12.1 In the event the Jury Trial Waiver set forth above is not
enforceable, the parties elect to proceed under this Judicial Reference
Provision.

               12.2 With the exception of the items specified in clause (c),
below, any controversy, dispute or claim (each, a "Claim") between the parties
arising out of or relating to this Loan and Security Agreement or any other
document, instrument or agreement between the undersigned parties (collectively
in this Section, the "Comerica Documents"), will be resolved by a reference
proceeding in California in accordance with the provisions of Sections 638 et
seq. of the California Code of Civil Procedure ("CCP"), or their successor
sections, which shall constitute the exclusive remedy for the resolution of any
Claim, including whether the Claim is subject to the reference proceeding.
Except as otherwise provided in the Comerica Documents, venue for the reference
proceeding will be in the state or federal court in the county or district where
the real property involved in the action, if any, is located or in the state or
federal court in the county or district where venue is otherwise appropriate
under applicable law (the "Court").

               12.3 The matters that shall not be subject to a reference are the
following: (i) nonjudicial foreclosure of any security interests in real or
personal property, (ii) exercise of self-help remedies (including, without
limitation, set-off), (iii) appointment of a receiver and (iv) temporary,
provisional or ancillary remedies (including, without limitation, writs of
attachment, writs of possession, temporary restraining orders or preliminary
injunctions). This reference provision does not limit the right of any party to
exercise or oppose any of the rights and remedies described in clauses (i) and
(ii) or to seek or oppose from a court of competent jurisdiction any of the
items described in clauses (iii) and (iv). The exercise of, or opposition to,
any of those items does not waive the right of any party to a reference pursuant
to this reference provision as provided herein.

               12.4 The referee shall be a retired judge or justice selected by
mutual written agreement of the parties. If the parties do not agree within ten
(10) days of a written request to do so by any party, then, upon request of any
party, the referee shall be selected by the Presiding Judge of the Court (or his
or her representative). A request for appointment of a referee may be heard on
an ex parte or expedited basis, and the parties agree that irreparable harm
would result if ex parte relief is not granted. Pursuant to CCP Section 170.6,
each party shall have one peremptory challenge to the referee selected by the
Presiding Judge of the Court (or his or her representative).

               12.5 The parties agree that time is of the essence in conducting
the reference proceedings. Accordingly, the referee shall be requested, subject
to change in the time periods specified herein for good cause shown, to (i) set
the matter for a status and trial-setting conference within fifteen (15) days
after the date of selection of the referee, (ii) if practicable, try all issues
of law or fact within one hundred twenty (120) days after the date of the
conference and (iii) report a statement of decision within twenty (20) days
after the matter has been submitted for decision.

               12.6 The referee will have power to expand or limit the amount
and duration of discovery. The referee may set or extend discovery deadlines or
cutoffs for good cause, including a party's failure to provide requested
discovery for any reason whatsoever. Unless otherwise ordered based upon good
cause shown, no party shall be entitled to "priority" in conducting discovery,
depositions may be taken by either party upon seven (7) days written notice, and
all other discovery shall be responded to within fifteen (15) days after
service. All disputes relating to discovery which cannot be resolved by the
parties shall be submitted to the referee whoso decision shall be final and
binding.

               12.7 Except as expressly set forth herein, the referee shall
determine the manner in which the reference proceeding is conducted including
the time and place of hearings, the order of presentation of evidence, and all
other questions that arise with respect to the course of the reference
proceeding. All proceedings and hearings conducted before the referee, except
for trial, shall be conducted without a court reporter, except that when any
party so requests, a court reporter will be used at any hearing conducted before
the referee, and the referee will be provided a courtesy copy of the transcript.
The party making such a request shall have the obligation to arrange for and pay
the court reporter. Subject to the referee's power to award costs to the
prevailing party, the parties will equally share the cost of the referee and the
court reporter at trial.

<PAGE>

               12.8 The referee shall be required to determine all issues in
accordance with existing case law and the statutory laws of the State of
California. The rules of evidence applicable to proceedings at law in the State
of California will be applicable to the reference proceeding. The referee shall
be empowered to enter equitable as well as legal relief, enter equitable orders
that will be binding on the parties and rule on any motion which would be
authorized in a court proceeding, including without limitation motions for
summary judgment or summary adjudication. The referee shall issue a decision at
the close of the reference proceeding which disposes of all claims of the
parties that are the subject of the reference. Pursuant to CCP Section 644, such
decision shall be entered by the Court as a judgment or an order in the same
manner as if the action had been tried by the Court and any such decision will
be final, binding and conclusive. The parties reserve the right to appeal from
the final judgment or order or from any appealable decision or order entered by
the referee. The parties reserve the right to findings of fact, conclusions of
laws, a written statement of decision, and the right to move for a new trial or
a different judgment which new trial, if granted, is also to be a reference
proceeding under this provision.

               12.9 If the enabling legislation which provides for appointment
of a referee is repealed (and no successor statute is enacted), any dispute
between the parties that would otherwise be determined by reference procedure
will be resolved and determined by arbitration. The arbitration will be
conducted by a retired judge or justice, in accordance with the California
Arbitration Act Section 1280 through Section 1294.2 of The CCP as amended from
time to time. The limitations with respect to discovery set forth above shall
apply to any such arbitration proceeding.

               12.10 THE PARTIES RECOGNIZE AND AGREE THAT ALL CONTROVERSIES,
DISPUTES AND CLAIMS RESOLVED UNDER THIS REFERENCE PROVISION WILL BE DECIDED BY A
REFEREE AND NOT BY A JURY. AFTER CONSULTING (OR HAVING HAD THE OPPORTUNITY TO
CONSULT) WITH COUNSEL OF ITS, HIS OR HER OWN CHOICE, EACH PARTY KNOWINGLY AND
VOLUNTARILY, AND FOR THE MUTUAL BENEFIT OF ALL PARTIES, AGREES THAT THIS
REFERENCE PROVISION WILL APPLY TO ANY CONTROVERSY, DISPUTE OR CLAIM BETWEEN OR
AMONG THEM ARISING OUT OF OR IN ANY WAY RELATED TO, THIS LOAN AND SECURITY
AGREEMENT OR THE OTHER COMERICA DOCUMENTS."

     9. A new Section 14 is added to the Agreement to read in its entirety as
follows:

          "14 CO-BORROWERS.

               14.1 Co-Borrowers. Borrowers are jointly and severally liable for
the Obligations and Bank may proceed against one Borrower to enforce the
Obligations without waiving its right to proceed against the other Borrower.
This Agreement and the Loan Documents are a primary and original obligation of
each Borrower and shall remain in effect notwithstanding future changes in
conditions, including any change of law or any invalidity or irregularity in the
creation or acquisition of any Obligations or in the execution or delivery of
any agreement between Bank and any Borrower. Each Borrower shall be liable for
existing and future Obligations as fully as if all of the Credit Extensions were
advanced to such Borrower. Bank may rely on any certificate or representation
made by any Borrower as made on behalf of, and binding on, all Borrowers,
including without limitation Advance Request Forms, Borrowing Base Certificates
and Compliance Certificates. Borrowers are jointly and severally liable for the
Obligations and Bank may proceed against one or more of the Borrowers to enforce
the Obligations without waiving its right to proceed against any of the other
Borrowers. Each Borrower appoints each other Borrower as its agent with all
necessary power and authority to give and receive notices, certificates or
demands for and on behalf of both Borrowers, to act as disbursing agent for
receipt of any Advances on behalf of each Borrower and to apply to Bank on
behalf of each Borrower for Advances, any waivers and any consents. This
authorization cannot be revoked, and Bank need not inquire as to one Borrower's
authority to act for or on behalf of another Borrower.

               14.2 Subrogation and Similar Rights. Notwithstanding any other
provision of this Agreement or any other Loan Document, each Borrower
irrevocably waives, until all obligations are paid in full and Bank has no
further obligation to make Credit Extensions to Borrower, all rights that it may
have at law or in equity (including, Without limitation, any law subrogating the
Borrower to the rights of Bank under the Loan Documents) to seek contribution,
indemnification, or any other form of reimbursement from any other Borrower, or
any other Person now or hereafter primarily or secondarily liable for any of the
Obligations, for any payment made by the


                                       -5-

<PAGE>

Borrower with respect to the Obligations in connection with the Loan Documents
or otherwise and all rights that it might have to benefit from, or to
participate in, any security for the Obligations as a result of any payment made
by the Borrower with respect to the Obligations in connection with the Loan
Documents or otherwise. Any agreement providing for indemnification,
reimbursement or any other arrangement prohibited under this Section shall be
null and void. If any payment is made to a Borrower in contravention of this
Section, such Borrower shall hold such payment in trust for Bank and such
payment shall be promptly delivered to Bank for application to the Obligations,
whether matured or unmatured.

               14.3 Waivers of Notice. Each Borrower waives, to the extent
permitted by law, notice of acceptance hereof; notice of the existence, creation
or acquisition of any of the Obligations; notice of an Event of Default except
as set forth herein; notice of the amount of the Obligations outstanding at any
time; notice of any adverse change in the financial condition of any other
Borrower or of any other fact that might increase the Borrower's risk;
presentment for payment; demand; protest and notice thereof as to any
instrument; and all other notices and demands to which the Borrower would
otherwise be entitled by virtue of being a co-borrower or a surety. Each
Borrower waives any defense arising from any defense of any other Borrower, or
by reason of the cessation from any cause whatsoever of the liability of any
other Borrower. Bank's failure at any time to require strict performance by any
Borrower of any provision of the Loan Documents shall not waive, alter or
diminish any right of Bank thereafter to demand strict compliance and
performance therewith. Each Borrower also waives any defense arising from any
act or omission of Bank that changes the scope of the Borrower's risks
hereunder. Each Borrower hereby waives any right to assert against Bank any
defense (legal or equitable), setoff, counterclaim, or claims that such Borrower
individually may now or hereafter have against another Borrower or any other
Person liable to Bank with respect to the Obligations in any manner or
whatsoever.

               14.4 Subrogation Defenses. Until all Obligations are paid in full
and Bank has no further obligation to make Credit Extensions to Borrower, each
Borrower hereby waives any defense based on impairment or destruction of its
subrogation or other rights against any other Borrower and waives all benefits
which might otherwise be available to it under California Civil Code Sections
2809, 2810, 2819,2839, 2845, 2848, 2849, 2850, 2899, and 3433 and California
Code of Civil Procedure Sections 580a, 580b, 580d and 726, as those statutory
provisions are now in effect and hereafter amended, and under any other similar
statutes now and hereafter in effect.

               14.5 Right to Settle, Release.

                    (a) The liability of Borrowers hereunder shall not be
diminished by (i) any agreement, understanding or representation that any of the
Obligations is or was to be guaranteed by another Person or secured by other
property, or (ii) any release or unenforceability, whether partial or total, of
rights, if any, which Bank may now or hereafter have against any other Person,
including another Borrower, or property with respect to any of the Obligations.

                    (b) Without notice to any Borrower and without affecting the
liability of any Borrower hereunder, Bank may (i) compromise, settle, renew,
extend the time for payment, change the manner or terms of payment, discharge
the performance of, decline to enforce, or release all or any of the Obligations
with respect to a Borrower, (ii) grant other indulgences to a Borrower in
respect of the Obligations, (iii) modify in any manner any documents relating to
the Obligations with respect to a Borrower, (iv) release, surrender or exchange
any deposits or other property securing the Obligations, whether pledged by a
Borrower or any other Person, or (v) compromise, settle, renew, or extend the
time for payment, discharge the performance of, decline to enforce, or release
all or any obligations of any guarantor, endorser or other Person who is now or
may hereafter be liable with respect to any of the Obligations.

               15.6 Subordination. All indebtedness of a Borrower now or
hereafter arising held by another Borrower is subordinated to the Obligations
and the Borrower holding the indebtedness shall take all actions reasonably
requested by Bank to effect, to enforce and to give notice of such
subordination."

     10. All references in the Agreement to Bank's address at 2321 Rosecrans
Ave., Suite 5000, El Segundo, CA 90245, shall mean and refer to 75 E Trimble
Road, San Jose, CA 95131.

     11. Exhibit A to the Agreement is hereby amended to include Exhibit A-1
attached hereto.

hereto.

     13. Exhibit D is added to the Agreement in the form of Exhibit D attached
hereto.

     14. For good and valuable consideration received, and intending to be
legally bound, Jadeon hereby acknowledges and agrees that, upon the execution
and delivery by Jadeon of this Amendment, it shall for all purposes be joined
to, and become, as of the date of this Amendment, a Borrower to, and shall
assume and incur the obligations of a Borrower under the Agreement and all other
Loan Documents, and do hereby grant to Bank a continuing security interest in
all presently existing and hereafter acquired or arising Collateral to secure
prompt repayment of any and all Obligations and to secure prompt performance by
each Borrower of its covenants and duties under the Loan Documents.

     15. No course of dealing on the part of Bank or its officers, nor any
failure or delay in the exercise of any right by Bank, shall operate as a waiver
thereof, and any single or partial exercise of any such right shall not preclude
any later exercise of any such right. Bank's failure at any time to require
strict performance by a Borrower of any provision shall not affect any right of
Bank thereafter to demand strict compliance and performance. Any suspension or
waiver of a right must be in writing signed by an officer of Bank.

     16. Unless otherwise defined, all initially capitalized terms in this
Amendment shall be as defined in the Agreement. The Agreement, as amended
hereby, shall be and remain in full force and effect in accordance with its
respective terms and hereby is ratified and confirmed in all respects. Except as
expressly set forth herein, the execution, delivery, and performance of this
Amendment shall not operate as a waiver of, or as an amendment of, any right,
power, or remedy of Bank under the Agreement, as in effect prior to the date
hereof.

     17. Each Borrower represents and warrants that the Representations and
Warranties contained in the Agreement are true and correct as of the date of
this Amendment, and that no Event of Default has occurred and is continuing.

     18. As a condition to the effectiveness of this Amendment, Bank shall have
