The foregoing notwith­standing, LICENSEE’s rights and license are subject to the rights of the U.S. Government pursuant to any funding agreement between NCAT and the Government.    2.02 -     LICENSEE may grant sublicenses and extend any license granted to LICENSEE to its Affiliates.  Any such sublicenses or extensions are subject to the terms of this Agreement and may be no less favorable to NCAT than is this license.  A copy of each sublicense must be provided to NCAT no later than 45 days after execution date.  LICENSEE agrees to be responsible for the performance hereunder by its Affiliates and sublicensees, if any.

3.02 -     LICENSEE will use its best efforts to have the Subject Technology cleared for marketing in those countries in which LICENSEE intends to sell Licensed Products by the responsible government agencies requiring such clearance.  To accomplish such clearances at the earliest possible date, LICENSEE agrees to file, according to the usual practice of LICENSEE, any necessary data with such government agencies.  Should LICENSEE terminate this Agreement, LICENSEE agrees to assign its full interest and title in such market clearance application, including all data relating thereto, to NCAT at no cost to NCAT.
