6.       PREPAYMENTS BY DISTRIBUTOR; PAYMENT BY DISTRIBUTOR .

         6.1      PREPAYMENTS BY DISTRIBUTOR. Upon the execution of this
agreement and the execution of a confirmed purchase order from a valid customer
(as determined by Distributor) issued to Distributor for approximately 1000
wafers per month for a period of 12 months, Distributor will pay Supplier a
prepayment toward the purchase of Products of $50,000 plus accrued interest
which is represented by an existing note receivable from Supplier to Distributor
and $95,000 in the form of a cashiers check and, subject to the other provisions
of this Section 6.1, will continue to make continuing $95,000 monthly
prepayments. These payments will be referred to as "PrePayments" and will be
accrued as prepayments against any obligations by Distributor to make payments
pursuant to Section 6.3 below. When the aggregate amount of payments to be made
to Supplier pursuant to Section 6.3 below have exceeded the sum total of all
PrePayments, this Section 6.1 will no longer apply and no further PrePayments
will be made. The note receivable for $50,000 will be so that it is no longer in
default, but instead in a current status that is payable on request by
Distributor due, and this note receivable will be canceled when all Prepayments
as well as the $50,000 of this note and accrued interest on the note have been
paid to Distributor. Until such time, any and all payments due to Supplier
pursuant to Section 6.1, will be retained by Distributor and applied against the
then outstanding balance of PrePayments. On the date this Section 6.1 no longer
applies, Supplier will pay Distributor a one-time PrePayment advance charge of
one percent of the aggregate amount of PrePayments made.

         6.2      CHANGES TO PREPAYMENT AMOUNT. Should the Supplier and
Distributor agree that the monthly prepayments require to be altered due to a
change in business conditions, then the prepayment amount or schedule can be
revised, subject to the following guidelines:

                  6.2.1 Where increases to the prepayment amount are suggested
due to increases in volume of production, such changes shall be approximately
proportional to the change in direct variance cash expense to achieve the
desired production increase. Variance cash expense increases shall include
incremental direct labor and incremental direct materials.

                  6.2.2 Where changes are made for reasons other than increasing
manufacturing volume, the Distributor and the Supplier agree that the
Distributor Project Manager may authorize a monthly alteration in the
prepayment, subject solely to his discretion.

         6.3      PAYMENTS FOR PRODUCTS. Distributor will make payments to the
Supplier for the Products supplied and delivered by Supplier equal to the
collected accounts receivable for Product sales less

                  o        8% of such collections for processed wafers delivered
                           in the first 4 months of this Agreement; 10% for
                           deliveries in the subsequent 4 months; and 11%
                           thereafter on all products delivered to the named
                           Customer Protek Devices.

                  o        11% of collections on all other processed wafers over
                           $150 selling price.

                  o        17% of collections for Products encapsulated by or on
                           behalf of Supplier.

         6.4      PAYMENT DATE. Payments will be made by the fifteenth day
following the last day of the calendar month in which the Products were
delivered, subject to the provisions of Section 6.1 above.

         6.5      DISTRIBUTOR PRICING. The Distributor is free to determine its
own resale prices for the Products. Although the Supplier may suggest list
prices, these are suggestions only and are not binding in any way. The
Distributor will not use price to jeopardize the commercialization of the
product.

         6.6      DEMAND PAYMENT. Notwithstanding Section 6.1, Supplier will pay
Distributor any then outstanding PrePayment amount that has not been offset by
payments to be made by Distributor under Section 6.2, at any time requested by
the Distributor.

         6.7      RIGHT TO REVIEW RECORDS. The Supplier will provide the
Distributor's Project Manager with a written monthly report by the 10th day of
each month showing an accounting for the distributions of all prepayments made
by Distributor to Supplier. The Supplier will agree to have these project
records promptly reviewed for accuracy and completeness by an outside accounting
firm acceptable to and paid for by the Distributor, if so requested by the
Distributor.

7.       SHIPMENT.

         7.1      SHIPMENT. All Products will be shipped by the Supplier F.O.B.

hold harmless the Distributor for damages or expenses resulting from any claim,
suit or proceeding brought against the Distributor on the issue of product
liability related to the Products or any part thereof. The Distributor agrees
that the Supplier has the right to defend, or at its option to settle, and the
Supplier agrees, at its own expense, to defend or at its option to settle, any
claim, suit or proceeding brought against the Distributor or its Customer on the
issue of product liability, subject to the limitations set forth in this
Agreement. The Supplier shall have sole control of any such action or settlement
negotiations, and the Supplier agrees to pay, subject to the limitations of this
Agreement, any final judgment entered against the Distributor or its customer on
such issue in any such suit or proceeding defended by the Supplier.

         9.2      DISTRIBUTOR INDEMNIFICATION. The Distributor shall indemnify
and hold harmless the Supplier for damages or expenses resulting from any claim,

of Products, and that Supplier has sole control of funds received. To prevent
advancing funds from Distributor to Supplier that for whatever reason are not
deployed in a productive way for mutual benefit under this agreement,
Distributor may terminate this contract upon Supplier failing to deliver
Products on the agreed upon date. In addition, this Agreement may be terminated
by either party upon written notice of termination given by registered or
certified mail, in which event this Agreement shall terminate 60 days from the
date of mailing of the notice or upon the occurrence of any of the following
circumstances.

insolvency law is initiated by the other party, or is initiated against the
other party and not dismissed or stayed within 60 days;

                  11.1.2 A material breach by the other party of any of the
terms of this Agreement, which breach is not remedied by the other party within

         11.2     FULFILLMENT OF OBLIGATIONS. The termination of this Agreement
shall not otherwise release either party from its obligation to pay any sum that
may be then or thereafter owing to the other party nor operate to discharge any
liability that had been incurred by either party prior to any such termination.
Except as qualified by the preceding sentence, neither party shall, by reason of
the termination of this Agreement, be liable to the other for any damages
(whether direct, consequential or incidental to and including loss of profit or
prospective profits of any kind) sustained or arising out of any such
termination.

         11.3     EFFECT OF TERMINATION AND SURVIVAL. Upon termination of this
Agreement, the Distributor may continue to dispose of its existing inventories
of Products, but the Distributor shall otherwise discontinue all further
promotion, marketing, and support of the Products. Upon termination of this

automatically be accelerated and all such invoices shall become due and payable.
All orders or portions thereof remaining unshipped as of the effective date of
termination may be canceled by the Supplier, at its option, to the extent they
call for delivery more than 60 days after the date of termination. Upon
termination of this Agreement by Supplier other than a for a material breach by
Distributor, the Supplier will repurchase all of the entire remaining inventory
of the Products held by the Distributor, and Products in transit to the
Distributor, at the Distributors sole discretion. The Supplier shall pay the
Distributor for all Products so repurchased an amount equal to the landed cost
paid by the Distributor. Upon receipt of any Products so reacquired from the
Distributor, the Supplier shall issue a check to the Distributor within 10 days

obligation described in that waiver.

         14.4     FORCE MAJEURE. Neither party will be deemed in default of this
Agreement to the extent that performance of its obligations, or attempts to cure
any breach, are delayed or prevented by reason of circumstance beyond its
reasonable control, including without limitation fire, natural disaster,
earthquake, accident or other acts of God ("Force Majeure"), provided that the
party seeking to delay its performance gives the other written notice of any
such Force Majeure within 15 days after the discovery of the Force Majeure, and
further provided that such party uses its good faith efforts to cure the Force
Majeure. If there is a Force Majeure, the time for performance or cure will be
extended for a period equal to the duration of the Force Majeure. This section
shall not be applicable to any payment obligations of either party.

         14.5     GOVERNING LAW. This Agreement shall be governed by and
construed and enforced in accordance with the laws of the United States of
America and the State of Arizona, without regard to conflict of laws provisions
of that state. As between the parties hereto, the United Nations convention

                                  Page 9 of 14

Description of Products

THYRISTOR

Thyristor is a semiconductor device that can be turned on via a gate signal. By
way of example and not of limitation, the thyristor model is simulated as a
resistor (Ron), an inductor (Lon), and a DC voltage source (Vf), connected in
series with a switch. The switch is controlled by a logical signal depending on
the voltage Vak, the current Iak and the gate signal (g).












The Thyristor block also contains a series Rs-Cs snubber circuit that can be
connected in parallel with the thyristor device.

The static VI characteristic of this model is shown in figure below.













The thyristor device turns on when the anode-cathode voltage is greater than Vf
and a positive pulse signal is applied at the gate input (g>0). The pulse height
must be greater than zero and last long enough to allow the thyristor anode
current to become larger than the latching current Il.

The thyristor device turns off when the current flowing in the device becomes
zero (Iak=0) and a negative voltage appears across the anode and cathode for at
least a period of time equal to the turn-off time Tq. If the voltage across the
device becomes positive within a period of time less than Tq, the device will
turn on automatically even if the gate signal is low (g = 0) and the anode
current is less than the latching current. Furthermore, if during turn on, the


                                 Page 11 of 14
   12
device current amplitude stays below the latching current level specified in the
dialog box, the device turns off after the gate signal level becomes low (g =
0).

The turn-off time Tq represents the carrier recovery time: it is the time
interval between the instant the anode current has decreased to zero and the
instant when the thyristor is capable of withstanding positive voltage Vak
without turning on again.

Supplier produces Thyristors on 4" silicon wafers with a variety of different
holding current and surge current capabilities.

SCHOTTKY DIODES

Schottky diode is a special type of diode with a very low forward-voltage drop.
When current flows through a diode, it has some internal resistance to that
current flow, which causes a small voltage drop across the diode terminals. A
normal diode has between 0.7-1.7 volt drops, while a Schottky diode voltage drop
is between approximately 0.15-0.45 - this lower voltage drop translates into
higher system efficiency.

different holding current and surge current capabilities
