8.  NON-COMPETITION

         8.1          From the date  hereof  until the  acceptance  of the Final
                      Deliverables,  and for a period of ten  years  thereafter,
                      GDA shall not supply or agree to supply to any party other
                      than Nexar  technology  with a form  factor  substantially
                      similar to the Boards or technology that will or is likely
                      to be directly  competitive with the [CMD]. The provisions
                      of  this  paragraph  shall  survive  termination  of  this
                      Agreement.

9.  DELIVERY AND ACCEPTANCE OF DELIVERABLES

         9.1          GDA shall deliver various Deliverables at the times and in
                      the  manner   specified  in  the   Milestone  and  Payment
                      Schedule.

         9.2          If GDA fails to make timely delivery of any Deliverable as
                      specified in the Milestone and Payment Schedule, Nexar may
                      give GDA notice of the  failure.  After such  notice,  GDA
                      shall  have  thirty  (30)  days  to  make  the   specified
                      delivery.  Failure to submit the Deliverables  within such
                      period shall be a material breach that shall entitle Nexar
                      to  terminate  this  Agreement  in  accordance   with  the
                      provisions on Termination.

         9.3          Nexar may inspect and test each of the  Deliverables  when
                      received to determine  if it conforms to the  requirements
                      of the Specifications. Any

                                      - 4 -





                      Deliverable  not rejected by Nexar within thirty (30) days
                      shall be deemed accepted.

         9.4          If any  Deliverable  is  rejected,  Nexar  shall  give GDA
                      notice of the rejection and the reasons for rejection. GDA
                      shall  then have  thirty  (30) days to cure  deficiencies.
                      After  resubmission  within  such  thirty (30) day period,
                      Nexar may again inspect the Deliverable to confirm that it
                      conforms to  requirements  of the  Specifications.  If the
                      resubmitted   Deliverable   does   not   conform   to  the
                      requirements  of this  Agreement,  the  failure  will be a
                      material breach that shall entitle Nexar to terminate this
                      Agreement   in   accordance   with   the   provisions   on
                      Termination.  If the resubmitted  Deliverable is rejected,
                      Nexar  shall give  notice to GDA  stating  the reasons for
                      rejection.

         9.5          Notice of failure to make timely delivery,  rejection,  or
                      subsequent  resubmission shall not affect the due date for
                      subsequent  Deliverables  as  required  by this  Agreement
                      unless otherwise agreed in writing.

         9.6          If the Final  Deliverables in any material  respect do not
                      conform to the Specifications,  and such non-conformity is
                      not cured as provided in this Agreement,  the failure will
                      be a material breach that shall entitle Nexar to terminate
                      this  Agreement  in  accordance  with  the  provisions  on
                      Termination.  Alternatively,  Nexar,  at its  option,  may
                      accept the Final  Deliverables as non-  conforming.  If it
                      does so, it shall give  prompt  notice to GDA  stating the
                      known defects,  and may withhold and deduct,  from amounts
                      otherwise  due and payable to GDA upon  acceptance  of the
                      Final Deliverables, the amount of reasonable out-of-pocket
                      costs to correct,  modify,  and/or  complete the Boards in
                      accordance with the Specifications. From time to time, and
                      as soon as is  practicable,  Nexar shall  provide GDA with
                      notice of all sums  withheld  and  expended and shall turn
                      over to GDA all  funds  withheld  that are not so  applied
                      when such remedial work is completed.

         9.7          GDA  shall  provide  to Nexar or to such  other  person as
                      Nexar shall  designate,  from time to time,  as reasonably
                      required before  production of the Boards,  all assistance
                      and  information  reasonably  necessary  to ensure  that a
                      Technical  Manual for each of the Boards is  complete  and
                      accurate.  GDA shall review a draft of each such Technical
                      Manual  upon  Nexar's  request  and  promptly  provide all
                      corrections  required  to  Nexar,  for  which  review  and
                      correction  Nexar  shall  pay GDA at the rate of [CMD] per
                      hour.

10.  PAYMENT

                      Schedule. Upon acceptance of each Deliverable, Nexar shall

                      notice of the  failure to pay.  The failure to pay, if not
                      cured within thirty (30) days after notice,  shall entitle
                      GDA to terminate  this  Agreement in  accordance  with the
                      provisions on Termination.

                      the Boards will perform in substantial conformity with the
                      Specifications.  However,  GDA and Nexar agree that due to
                      the nature of complex  integrated  circuit  boards such as

                      DAMAGES.

                      efforts  to  provide  to  Nexar  all  corrections   and/or
                      modifications  necessary  to  correct  problems,   logical
                      errors, and bugs in the Boards reported to GDA in writing.
                      The first [CMD] hours of the efforts of GDA's employees on
                      such tasks  shall be without  charge.  Thereafter  GDA may
                      bill for the time of its employees at [CMD] per hour. Such
                      bills  may be  rendered  to  Nexar  at  month  end and are

                      Nexar's modification of the Boards.

         13.2         If GDA fails to correct any problem, logical error, or bug
                      reported  during the Warranty  Period  within  thirty (30)
                      days of  notice,  Nexar may  contract  for such work to be
                      done by any third  party that agrees in writing to hold in
                      confidence the Confidential Information of GDA.

                      and fees, including court costs and reasonable  attorneys'
                      fees  and  expenses,   or  similar  adverse  consequences,

15.  FUTURE PROJECTS; RIGHT OF FIRST REFUSAL

         15.1         Nexar  and GDA  agree to work  together  in good  faith to
                      reach  agreement for development of the following [CMD] on
                      specification  and milestone  and payment  terms  mutually

                      agrees to provide Nexar with a right of first refusal, and
                      to work with  Nexar in good  faith to reach  agreement  on
                      mutually  acceptable terms, with respect to any future GDA

                      customer,  or  prospective  customer,  of GDA  other  than
                      Nexar) which  relates to Nexar's  current or  demonstrably
                      anticipated products or research and development, prior to
                      proposing  to do any such  development  work for any other
                      party. Nexar agrees to notify GDA whether it will exercise
                      its right of first  refusal  within  seven (7) days  after

                      to offer such  proposal to third  parties on terms no less
