    2.
       I
      will
      not, except with the prior written consent of the Company, or except if I am
      acting as an employee of the Company solely for the benefit of the Company
      in
      connection with the Company's
      business and in accordance with the Company's business practices and employee
      policies, at any time during or following the term of my employment by the
      Company, directly or indirectly, disclose, divulge, reveal, report, publish,
      transfer or use, for any purpose whatsoever, any Confidential Information.
      

    

    3.
       I
      will
      make full and prompt disclosure to the Company of all inventions, improvements,
      modifications, discoveries, methods and developments (all of which are
      collectively termed "Developments" hereinafter), whether patentable or not,
      made
      or conceived by me or under my direction during my employment, whether or not
      made or conceived during normal working hours or on the premises of the Company.
      However, this Paragraph 3 shall not cover Developments which do not relate
      to
      the Company's actual or anticipated business or research and development as
      conducted by the Company, or expressed by the Company to me, during the term
      of
      my employment, provided that such Developments are made or conceived by me
      entirely during other than the Company working hours, and not on the Company's
      premises and not with the use of the Company's equipment, supplies, facilities,
      tools, devices or trade secret information. I agree to assign, and do hereby
      assign, to the Company any right, title or interest I may have in any
      Developments covered by this Paragraph 3. I agree to execute any instruments
      and
      to do all other things reasonably requested by the Company (both during and
      after my employment with the Company) in order to vest more fully in the Company
      all ownership rights in those Developments hereby transferred by me to the
      Company. If anyone or more of such items are protectable by copyright and are
      deemed in any way to fall within the definition of "work made for hire," as
      such
      term is defined in 17 U. S. C. Section101,
      such
      work shall be considered a "work made for hire," the copyright of which shall
      be
      owned solely, completely and exclusively by the Company. If anyone or more
      of
      the aforementioned items are protectable by copyright and are not considered
      to
      be included in the categories of works covered by the "work made for hire"
      definition contained in 17 U.S. C. Section 101, such work shall be deemed to
      be
      assigned and transferred completely and exclusively to the Company by virtue
      of
      my execution of this letter. Upon request by the Company, I agree to assign
      to
      the Company all Developments covered by this Paragraph 3 and any patents or
      patent applications covering such Developments and to execute and deliver such
      assignments, patents and applications, and other documents as the Company may
      direct and to fully cooperate with the Company to enable the Company to secure
      and patent or otherwise protect such Developments in any and all countries.
      

    

    4. I
      hereby
      represent that, to the best of my knowledge, there is no legal prohibition
      including, but not limited to, an agreement with any former employer that might
      prevent me from performing my contractual obligations with the Company. At
      the
      end of this Agreement I have set forth what I represent and warrant to be a
      complete list of all inventions, if any, patented or unpatented, including
      a
      brief description thereof (without revealing any confidential or proprietary
      information of any other party) which I may have conceived prior to my
      employment with the Company and for which I claim ownership or are in the
      physical possession of a former employer and which are therefore excluded from
      the scope of this Agreement. If there are no such exclusions from this
      Agreement, I have so indicated by writing "None" below in my own handwriting.
      

    

    
      
        
        

      

      
        
        

        
          

        

      

      
        
        

      

    

    

    5.
       I
      will
      not disclose to the Company, or induce the Company to use, any confidential
      information of other persons, corporations or firms, including my former
      employers (if any). 

    

    6.
       At
      the
      time I begin my employment and during the term of my employment with the
      Company, I will not engage in or become employed by or act on behalf of any
      other person, corporation or firm which is engaged in any business competitive
      with that of the Company, unless such contract has been approved by the Company
      in writing and signed by an appropriate personnel manager of the Company.

    

    7.
       Upon
      termination of my employment, unless my obligations are transferred to a
      subsidiary or affiliated company of the Company, I agree to leave with the
      Company all records. drawings, notebooks, computer data, software, computer
      tapes, and other documents pertaining to the Company's confidential information,
      whether prepared by me or others, and also any computers, instruments,
      equipment, tools or other devices in my possession which are owned by the
      Company. 

    

    8.
       This
      agreement supersedes any previous oral or written communications,
      representations, understandings or agreements with the Company or any
      representative of the Company. 

    

    9.
       My
      obligations under this Agreement shall survive the termination of my employment
      regardless of the manner of such termination, and shall be binding upon my
      heirs, executors and administrators.
