                      fail to make progress as to endanger performance in

                      creditors or if a petition under bankruptcy laws is filed
                      against it.

         b.       If this order is terminated pursuant to paragraph 14(a)iii,
                  NATIONAL, in addition to any other rights provided herein, may

                  in the manner, time and to the extent directed by NATIONAL,

         i.           any completed products, and

         ii.          such partially completed products and material, parts,
                      tool, dies, jigs, fixtures, plans, drawings, information,
                      and contract rights as the Seller has produced or acquired
                      for the performance of the terminated parts, and

         iii.         [OMITTED MATERIAL]

         iv.          Seller shall upon direction of NATIONAL, protect and
                      preserve property encompassed in this paragraph in the
                      possession of the Seller. Payment for completed products
                      delivered to and accepted by NATIONAL shall be an amount
                      agreed upon by Seller and NATIONAL. However, such amount
                      shall not exceed the order price per unit and Seller's
                      obligation hereunder to carry out NATIONAL's direction as
                      to delivery protection and

         C.       [OMITTED MATERIAL]

         Failure of NATIONAL to enforce any right under this clause shall not be
deemed a waiver of any other right hereunder. The rights and remedies of
NATIONAL under this clause shall not be exclusive and are in addition to any
other rights and remedies provided by law or under order. Seller however, shall
not be in default by reason of any delay in delivery hereunder, if such delay
arises out of causes beyond the control and without the fault or negligence of
Seller and such delay or any non-delivery is covered by section 2615(e) of the
Uniform Commercial Code. In the event of an excused delay, NATIONAL has the
option of extending the time o f performance to the extent the uncompleted

covered by this order in quantities not less that the ratio that this order
bears to the total orders o f the Seller for the same or similar products at the
time o f the excused delay, Seller will reasonably notify Buyer of any delay and

                  or part at any time by the giving of written notice to Seller
                  specifying the extent to which performance of work is
                  terminated.

         b.       After receipt of such notice, and except as other wise
                  directed by NATIONAL, the Seller shall stop work under this
                  order to the extent specified in the notice of termination.

         c.       Within thirty forty (45) days after receipt o f the notice o f
                  termination, the Seller shall submit to NATIONAL its written
                  termination claim. Failure of the Seller to submit its
                  termination claim as provided herein shall constitute an
                  unconditional and absolute waiver by the Seller of any claim
                  arising from NATIONAL's notice of termination.

         d.       Seller shall reasonably assess costs for raw materials, work
                  in process and sub-assemblies as may be included within its
                  termination claim to determine whether or not such items may
                  be used by Seller for the manufacture of associated products
                  or diverted for any other purpose and to correspondingly
                  reduce its termination claim by the value of such items. When
                  settlement has been made, title to any such items determined
                  not usable by Seller and charged to NATIONAL in the
                  termination claim shall vest in NATIONAL upon payment of the
                  claim and forthwith be delivered to NATIONAL at NATIONAL's
                  expense, under NATIONAL's shipping instructions.

         e.      [OMITTED MATERIAL]

         f.       Custom products: With respect to custom products, Seller's
                  termination claim shall consist solely of the following:

                                       5

<PAGE>

         i.       Completed products accepted by NATIONAL and not therefore paid
                  for the sum determined by multiplying the number of such
                  products by the unit price therefore as specified in this
                  order, and

         ii.      The total of the cost of work in process not to exceed the
                  average unit cost multiplied by the number of units in process
                  provided, however, that such number o f units in process shall
                  not exceed that amount which has been previously placed on a
                  firm release by NATIONAL. Such amounts shall not include any
                  costs attributable to Seller's products paid under
                  sub-paragraph f(i) above. The total sum to be paid to the
                  Seller under sub-paragraph f(i) and (ii) above shall not
                  exceed the total order price reduced by the amount o f payment
                  otherwise made and as further reduced by the price of work not
                  terminated under this order.

g.               In no event shall Seller be entitled to incidental or
                 consequential damages, costs preparing claims, attorney's
                 fees, cost of tooling or equipment sales or agent's
                 commissions.

h.      NATIONAL reserves the right to verify claims hereunder and Seller shall
        make available to NATIONAL, all appropriate records, upon request.

i.      Seller will use all available means to mitigate charges to Buyer.

16.     WAIVER:

         The failure of EITHER PARTY to enforce at any time any of the
provisions of this order, or to exercise any election or option provided herein,
or to require at any time performance by the other party of any of the
provisions hereof, shall in no way be construed to be a waiver of such
provisions, nor in any way to affect the validity of this agreement or any part
thereof, or the right of EITHER PARTY thereafter to endorse each and every such
provision.

17.      PATENTS, ROYALTIES AND ENCUMBRANCES:

such suit or proceeding is based on a claim that any hardware product furnished
hereunder, when used alone and not in combination with any other NON-ETS
manufactured product, constitutes an infringement of any patent or copyright.
ETS will pay any award against Buyer based on infringement only if Buyer
promptly notifies ETS in writing of the claim and permits ETS to participate in
the defense and agree to any settlement. If Buyer's use of such product or part
is enjoined, ETS will, at its sole discretion and expense, procure for Buyer the
right to continue using said product or replace the infringing product with a
non-infringing product or modify it so that it becomes non-infringing. If ETS is
unable to reasonably do any of the above, ETS will refund the purchase price of
the infringing product. ETS has no obligation for any claim o f infringement
arising from:

         a.       ETS' compliance with Buyer's designs, specifications or
                  instructions;

                                       6

         b.       equipment modifications by Buyer or a third party;

         c.       equipment use prohibited by ETS' specifications or related
                  application notes; or

         d.       use of ETS products in combination with products not supplied
                  by ETS.

         Sale of any product by ETS does not confer upon Buyer any license under
any patent or copyrights. The foregoing states ETS' entire obligation and the
exclusive remedies of Buyer hereto with respect to any alleged patent or
copyright infringement by any product furnished hereunder.

         Seller agrees to indemnify and hold harmless NATIONAL against all
claims, demands, costs and actions for actual or alleged infringements of patent
rights in the use, sale or resale of said products.

                  complies with all statutory regulations in the State of
                  California, or the States in which the work is being done.

         d.       Umbrella (including Products): with limits of not less than
                  $1,000,000 each occurrence or a $5,000,000 combined single
