of the Company set forth herein, the Employee agrees as follows:


         8.1 Covenant Not to Solicit  Employees of the Company.  During the Term
and for a period of one (1) year after the termination of this Agreement for any
reason  whatsoever,  the Employee  shall not solicit for  employment  any sales,
engineering  or other  technical or management  employee who was employed by the
Company or any of its subsidiaries during the Term.


         8.2 Non-Disclosure  Covenant.  The Employee recognizes and acknowledges
that,  in the course of his  employment,  the Employee will have access to trade
secrets,  proprietary  rights,  know-how,  and  other  confidential  information
(collectively,   "Confidential  Informaton")  of  the  Company,  3-D  and  their
respective


                                       -6-



subsidiaries,  including,  but not limited to,  information  concerning  seismic
data,  marketing  strategy,   technology,   techniques  and  know-how,  customer
specifications  and customer lists, cost figures,  budgets,  sales forecasts and
business plans. The Employee agrees that the disclosure of any such Confidential
Information  could be  harmful  to the  interests  of the  Company,  3-D or such
subsidiaries  and that,  during the Employee's  employment by the Company or its
subsidiaries,  the Employee will take appropriate  caution to safeguard all such
Confidential  Information,  and will not  during  the  Term or  thereafter  use,
disclose,  divulge  or  publish  any such  Confidential  Information  except  as
required by law or as the Employee's duties during the Employee's  employment by
the  Company or its  subsidiaries  may  require or as the Company may in writing
specifically consent.


         8.3 Proprietary  Information.  The Employee recognizes and acknowledges
that all documents,  manuals,  letters,  notebooks,  reports,  records, computer
programs or data banks and other evidences of trade secrets, proprietary rights,
know-how  and  other  confidential  information  of the  Company,  3-D and their
respective  subsidiaries,  including  copies  thereof,  whether  prepared by the
Employee  or others,  are the sole  property  of and belong  exclusively  to the
Company,  3-D and their  respective  subsidiaries,  and agrees that,  during the
Employee's  employment  by the Company or its  subsidiaries,  the Employee  will
under no  circumstances  remove any such material for use outside of his offices
except in connection  with the business of the Company  during the course of the
Employee's employment. In the event of


                                       -7-



the termination of this Agreement for any reason whatsoever,  the Employee shall
immediately  return to the  Company  any and all  documents,  manuals,  letters,
notebooks,  records,  computer  programs or data banks or other evidence of such
Confidential Information of the Company, including copies thereof, which are the
property of the Company, 3-D or any of their respective subsidiaries.


         8.4 Remedies.  The Employee hereby agrees that all restrictions imposed
upon the Employee hereunder are reasonable,  fair and valid, and all defenses to
the  strict  enforcement  of the  provisions  hereof  are  hereby  waived by the
Employee.  The  Employee  further  agrees  that  in the  event  of a  breach  or
threatened  breach of any of the  covenants  contained  in this  Section  8, the
Company's  remedy at law is likely to be  inadequate  and that  accordingly  the
Company will be entitled to obtain an injunction or other equitable  relief with
regard thereto  without  proving damages or that damages would not constitute an
adequate  remedy.  If the final  judgment of a court of  competent  jurisdiction
declares   that  any  term  or  provision  of  this  Section  8  is  invalid  or
unenforceable,  in whole or in part,  the  parties  hereto  agree that the court
making the determination of invalidity or unenforceability  shall have the power
to, and is hereby directed to, reduce the scope, duration or area of the term or
provision  by deleting  specific  words or phrases as  necessary  to comply with
applicable law or to be enforceable by a court of competent  jurisdiction  or by
replacing  any  invalid  or  unenforceable  term  or  provision  with a term  or
provision that is


                                       -8-



valid and  enforceable and that comes closest to expressing the intention of the
invalid  and  unenforceable  term or  provision,  and  this  Agreement  shall be
enforceable as so modified.


         8.5 Survival. The provisions of this Section 8 shall survive the Term.


         9.   Miscellaneous Provisions.


         9.1 Notices. All notices and demands of any kind which any party hereto
