      a)    This Agreement shall have a three (3) year term commencing on August
      1, 2007 and ending on July 31, 2010, unless earlier terminated pursuant to
      this Agreement's provisions. If this Agreement has not earlier terminated,
      or if neither party has notified the other by July 1, 2010 that it does
      not desire to renew this Agreement, then at the end of the initial term
      this Agreement shall be continue on a month to month basis until
      terminated by either party upon giving the other party a thirty (30) day
      notice of termination.
      b)    Either party may terminate this agreement with or without cause upon
      giving the other party a minimum of ninety (90) days prior written notice
      of such termination.
      c)    Ingen may terminate this Agreement upon thirty (30) days prior

      Oxyview ("Oxyview" or "Products") in North America, South America, Europe,
      Australia, New Zealand and Asia (the "Territory"). Ingen hereby represents
      and warrants that it has obtained all necessary regulatory approvals in
      the USA to sell the Oxyview in the USA. For those areas outside of the
      USA, Ingen is in the process of ISO 13485 Certification to sell Oxyview;
      although Oxyview has received FDA 510k clearance, and Ingen is DHS
      Certified, Ingen believes that the device may require ISO 13485
      Certification for international sales. Ingen is at the time of contracting
      reviewing a proposal from an ISO Consulting Firm to assist in Ingen's ISO
      13485 Certification. ISG and Ingen will work cooperatively to identify
      what international requirements exist to be met before Oxyview may be
      sold. If during the term of this Agreement Ingen obtains regulatory
      approvals in additional countries or areas to sell Oxyview during the term
      of this Agreement, the Territory and ISG's exclusivity shall be expanded
      to include such countries or areas if requested by ISG.
      b)    As a permitted exception to the appointment grant, Ingen can sell
      direct to aviation, military and fire departments that are located in the
      Territory -- see section 5 for more details on attribution of such direct
      to consumer sales between the parties.
      c)    ISG accepts such appointment. ISG shall use reasonable commercial
      efforts to exploit the rights granted to it in this Agreement and to
      implement a plan for commercializing Oxyview in the Territory.

      Ingen for any monetary shortfall payment or other penalty or liability of
      any kind related to such failure; however, Ingen may at its option
      terminate this Agreement upon thirty (30) days notice in the event of such

      forecast/projections based solely on past/current sales performance. ISG
      is not responsible for significant sales decreases or increases due to
      customer shifts. All orders will be accompanied with a purchase order.

      year) for sampling (demo) purposes, at no charge. Ingen agrees to also
