    NON-COMPETITION
      AND CONFIDENTIALITY

     

    11.1 Non-Competition

     

    The
      Executive recognizes and understands that in performing the duties and
      responsibilities of his employment as outlined in this Agreement, he will be
      a
      key employee of the Company and will occupy a position of high fiduciary trust
      and confidence, pursuant to which he has developed and will develop and acquire
      wide experience and knowledge with respect to all aspects of the services and
      businesses carried on by the Company and its Member Companies and the manner
      in
      which such businesses are conducted. It is the expressed intent and agreement
      of
      the Executive and of the Company that such knowledge and experience shall be
      used solely and exclusively in the furtherance of the business interests of
      the
      Company and its Member Companies and not in any manner detrimental to them.
      The
      Executive therefore agrees that so long as he is employed by the Company
      pursuant to this Agreement he shall not engage in any practice or business
      in
      competition with the business of the Company or any of its Member
      Companies.

    11.2 Confidentiality

     

    The
      Executive further recognizes and understands that in the performance of his
      employment duties and responsibilities as outlined in this Agreement, he will
      be
      a key employee of the Company and will become knowledgeable, aware and possessed
      of all confidential and proprietary information, know-how, data, strategic
      studies, techniques, knowledge and other confidential information of every
      kind
      or character relating to or connected with the business or corporate affairs
      and
      operations of the Company and its Member Companies and includes, without
      limitation, geophysical studies and data, market data, engineering information,
      shareholder data, client lists, compensation rates and methods and personnel
      information (collectively “Confidential
      Information”)
      concerning the business of the Company and its Member Companies. The Executive
      therefore agrees that, except with the consent of the Board, he will not
      disclose such Confidential Information to any unauthorized persons so long
      as he
      is employed by the Company pursuant to this Agreement and for a period of 24
      months thereafter; provided that the foregoing shall not apply to any
      Confidential Information which is or becomes known to the public or to the
      competitors of the Company or its Member Companies other than by a breach of
      this Agreement.

     

    11.3 Following
      Termination of Agreement

     

    Subject
      to this provision and without otherwise restricting the fiduciary obligations
      imposed upon, or otherwise applicable to the Executive as a result of the
      Executive having been a senior officer and key employee of the Company, the
      Executive shall not be prohibited from obtaining employment with or otherwise
      forming or participating in a business competitive to the business of the
      Company after termination of this Agreement and the Executive’s employment with
      the Company.
