6       OWNERSHIP OF TECHNOLOGY; CONFIDENTIALITY.
Song  recognizes  and  acknowledges  that during the course of his employment he
will have  access to certain  information  not  generally  known to the  public,
relating  to the  products,  sales or  business  of  CanTech,  which may include
without limitation software,  literature,  data,  programs,  customer or contact
lists, sources of supply,  prospects or projections,  manufacturing  techniques,
processes,  formulas,  research or  experimental  work,  work in process,  trade
secrets or any other  proprietary  or  confidential  matter  (collectively,  the
Confidential   Information).   Song  recognizes  and   acknowledges   that  this
Confidential  Information  constitutes  a valuable,  special and unique asset of
access to and  knowledge  of which are  essential  to the  performance of Song's
Duties.  Song  acknowledges and agrees that all such  Confidential  Information,
including without  limitation that which he conceives or develops,  either alone
or with others,  at any time during his  employment  CanTech is and shall remain
the exclusive  property of CanTech.  Song further  recognizes,  acknowledges and
agrees that in order to enable CanTech to perform  services for its customers or
clients,   such  customers  or  clients  may  furnish  to  CanTech  Confidential
Information concerning their business affairs, property, methods of operation or
other data,  that the goodwill  afforded to CanTech depends upon CanTech and its
employees  preserving the  confidentiality  of such  information,  and that such
information  shall be treated as  Confidential  Information  of CanTech  for all
purposes under this Agreement.
     6.1 Non-Disclosure.  Song agrees that, except as directed by CanTech,  Song
     will not at any time,  whether during or after his employment with CanTech,
     use or disclose to any person for any purpose other than for the benefit of
     CanTech any Confidential Information,  or permit any person to use, examine
     and/or  make  copies of any  documents,  files,  data or other  information
     sources which contain or are derived from Confidential Information, whether
     prepared by Song or otherwise  coming into CanTech's possession or control,
     without the prior written permission of CanTech.
     6.2 Possession.  Song agrees that upon request by CanTech, and in any event
     upon  termination  of  employment,  Song  shall  turn over to  CanTech  all
     Confidential  Information  in Song's  possession or under his control which
     was  created  pursuant  to, is  connected  with or is derived  from  Song's
     services  to  CanTech,  or which is  related  in any  manner  to  CanTech's
     business  activities or research and  development  efforts,  whether or not
     such materials are in Song's possession as of the date of this Agreement.
     6.3  Saving  Provision.  CanTech  and Song agree  that the  agreements  and
     covenants  not to compete  contained in the  preceding  paragraphs 5 and 6,
     including the scope of the restricted  activities described therein and the
     duration  and  geographic  extent  of  such  restrictions,   are  fair  and
     reasonably   necessary  for  the   protection  of  CanTech's   Confidential
     Information,  goodwill,  and other interests,  in light of all of the facts
     and  circumstances  of the  relationship  between Song and CanTech.  In the
     event a court of  competent  jurisdiction  should  decline to  enforce  any
     provision of the preceding  paragraphs,  such paragraphs shall be deemed to
     be modified  to restrict  Song's  competition  with  CanTech to the maximum
     extent, in both time and geography, which the court shall find enforceable.
7       INJUNCTIVE RELIEF.
Song acknowledges  that disclosure of any Confidential  Information or breach or
threatened breach of the non-competition  and non-disclosure  covenants or other
agreements  contained herein would give rise to irreparable injury to CanTech or
clients of CanTech,  which injury  would be  inadequately  compensable  in money
damages.  Accordingly,  CanTech or where appropriate,  a client of CanTech,  may
seek and obtain  injunctive  relief from the breach or threatened  breach of any
provision,  requirement or covenant of this Agreement, in addition to and not in
limitation of any other legal remedies which may be available.
