defense of the claim with its own counsel at its own expense,  and the Notifying

                                   ARTICLE 10

                                  Miscellaneous

         10.1  Brokers.  Seller  represents  and  warrants  to  Purchaser,   and
Purchaser  represents  and  warrants  to Seller,  that  neither it nor any party
acting on its behalf has incurred any liability,  either express or implied,  to
any broker, finder, financial adviser or similar person in respect of any of the
transactions  contemplated  hereby  except  to  Compass  Partners  who  shall be
compensated by Purchaser.  Purchaser  agrees to Indemnify  Seller  against,  and
Seller agrees to Indemnify  Purchaser against,  any liability resulting from any
agreement,  arrangement or understanding made by such Party with any third party
for  brokerage,  finders' or financial  advisory  fees or other  commissions  in
connection  with this Agreement or the  transactions  contemplated  hereby.  The
provisions of this Section shall survive any termination of this Agreement.

         10.2  Expenses.  Except  as  otherwise  specifically  provided  in this
Agreement,  each Party will pay its own expenses  incident to this Agreement and
the transactions  contemplated  hereby,  including legal and accounting fees and
disbursements.  The provisions of this Section shall survive any  termination of
this Agreement.

         10.3  Amendments  and Waivers.  The Parties  may, by written  agreement
signed by the Parties, modify any of the covenants or

agreements  or extend  the time for the  performance  of any of the  obligations
contained  in this  Agreement.  Either  Party may waive,  by written  instrument
signed by such Party, any inaccuracies in the  representations and warranties of
the other Party or  compliance  by the other  Party with any of its  obligations
contained  in this  Agreement  or in any  document  delivered  pursuant  to this
Agreement.  This Agreement may be amended only by written  instrument  signed by
the Parties.

         10.4 Transferability;  Successor and Assigns. The respective rights and
obligations  of each Party shall not be  assignable  by either Party without the
prior written  consent of the other except by operation of law. All of the terms
and provisions of this Agreement  shall be binding upon and inure to the benefit
of and be enforceable  by the Parties,  their  successors  and their  respective
permitted assigns.

         10.5 Bulk Transfer Laws.  Purchaser hereby waives  compliance by Seller
with the provisions of any Bulk Transfer Act. Seller shall  Indemnify  Purchaser
against any and all  liabilities  which may be asserted by third parties against
Purchaser  as a  result  of  non-compliance  with any such  Bulk  Transfer  Act;
provided,  however, that nothing herein shall prevent Seller from contesting any
such liabilities in good faith.

         10.6  Termination.  Seller may terminate  this Agreement if Closing has
not occurred on or prior to February 28, 1997. In the event that Closing  cannot
be held prior to such time because any of the  conditions  to Closing  cannot be
fulfilled and are not waived,

                                       52

neither of the Parties  shall have any  obligation  or  liability  of any nature
whatsoever  to the other Party  except that Seller  shall  return the Deposit to
Purchaser,  and all expenses incurred by any Party shall be for its own account;
provided,  however,  that no Party  shall be deemed to have waived any rights it
may have arising from the willful default of the other Party.

         10.13  Publicity.  No Party shall  issue any press  release or make any

by law or the regulations of any securities exchange.

         10.14  Parties  in  Interest.  Nothing  in this  Agreement,  express or

respective  successors and permitted  assigns any rights or remedies under or by
virtue of this Agreement, and no person shall assert any rights as a third party
beneficiary hereunder.

                                   ARTICLE 11

                              Restrictive Covenants

         11.1  Non-Competition.   Seller  agrees  that  it  shall  not,  without
Purchaser's  prior  written  consent,  prior to two  years  after  the  Closing,
directly or  indirectly  engage in the Business or otherwise in the  reclamation
and recovery of silicon  wafers;  provided,  however,  Seller may engage in such
business through any company acquired by Seller after the date of this Agreement
if such after-acquired  company was already engaged in such business at the time
of such  acquisition,  and the  revenues of such  company  attributable  to that
portion of the company  engaged in such  business  during the twelve (12) months
preceding Seller's  acquisition thereof did not exceed twenty-five percent (25%)
of the total revenues of such company during such period.

         11.2  Non-Solicitation  of  Employees.  In  furtherance  of and  not in
limitation of the  foregoing,  Seller agrees it will not for a period of two (2)
years from the Closing Date solicit or hire any of the current  employees of the
Business  unless it first receives the written consent of Purchaser or Purchaser
has terminated such employee.

         11.3 Confidentiality. For a period of five (5) years after the Closing,
Seller shall not disclose or use any of the  Intellectual  Property Rights being
sold to  Purchaser  hereunder  unless (a) it becomes  part of the public  domain
without  disclosure by Seller,  (b) is broadly  disseminated by the Purchaser to
third  parties  without  restriction,  (c) is disclosed  with the prior  written
consent of Purchaser, (d) is disclosed after notice to Purchaser pursuant to the
order or requirement of a court, administrative agency or other government body,
or (e) is  disclosed  to the  Seller  by a third  party  with no  obligation  of
confidence to Purchaser or the Netherlands Subsidiary.

         11.4  Invalidity.  In the  event  that  any of the  provisions  of this
Article 11 should ever be adjudicated to exceed the time, geographic, product or
service,  or other limitations  permitted by applicable law in any jurisdiction,
then the court  shall  have the power and shall  reform the  provisions  of this
Article 11 in such  jurisdiction  to the maximum  time,  geographic,  product or
service, or other limitation permitted by applicable law.
