    TOKYO, Aug. 3 /PRNewswire-FirstCall/ -- NEC Corporation (Nasdaq:   NIPNY)
 announced that it has concluded an agreement with SouthWest
 NanoTechnologies, Inc. (SWeNT(TM), note 1), by which it grants SWeNT(TM) a
 non-exclusive license under basic patents owned by NEC covering the carbon
 nanotube discovered by Dr. Sumio Iijima, a senior research fellow at NEC,
 in 1991.
     SWeNT(TM) manufactures and supplies carbon nanotube materials for a
 wide variety of applications worldwide employing its proprietary
 CoMoCAT(TM) process (note 2) that was invented independently at the
 University of Oklahoma in the U.S. Anticipating a rapid increase in demand
 for carbon nanotube materials in a wide variety of fields and applications,
 SWeNT(TM) has recognized the necessity to acquire a license from NEC under
 its basic patents in order to expand its business and has signed an
 agreement with NEC.
     "NEC's carbon nanotube patents are basic patents covering single and
 multi-walled carbon nanotubes, and licenses under our patents are essential
 for entities to manufacture or sell carbon nanotubes," said Keiji Ushijima,
 Executive Expert at NEC's Intellectual Asset Business Development and
 Licensing Division. "We are currently in negotiations with a number of
 entities worldwide who require a license from us under our patent rights,
 and we will continue to grant licenses to such entities, from venture
 companies to multinational corporations, with reasonable terms and
 conditions, in order to expand the markets of carbon nanotubes and their
     The carbon nanotube is drawing significant attention worldwide as a
 core material for nanotechnology. Owing to an extremely fine structure that
 has a diameter measuring on the nanometer-scale (thin tube-shaped material)
 and superior physical and chemical properties, the carbon nanotube is
 expected to be used for various applications including high-resolution AFM
 probes, flat panel displays, extremely lightweight and high-strength
 materials, high performance transistors, interconnect materials, fuel
 cells, ultra-sensitive sensors, absorbents and conductive coatings.
     NEC is actively supporting new business and value chain creation among
 licensees, trading companies and application manufacturers through the
 licensing of its patents, not only in the field of nanomaterials, but also
 in a wide variety of business and industrial fields. It will continue to
 advance the licensing of its patents in connection with carbon nanotubes
 and their applications worldwide. For more information please visit NEC

 database operated by NEC Corporation to introduce its intellectual assets
 to the market. These assets include a broad range of patents, technologies,
 know-how and engineering services.
     (1) SouthWest NanoTechnologies, Inc. is a privately held independent
         specialty chemical firm, manufacturing single wall carbon nanotubes
         for a broad array of specialty products. SWeNT(TM) was incorporated in
         April of 2001 to spin off nanotube research developed by the
         University of Oklahoma. For more information please access: .
     (2) CoMoCAT(TM) process: A catalytic method (CoMoCAT(R)) that produces
         single wall carbon nanotubes of high quality at very high selectivity,
         and with a remarkably narrow distribution of tube diameters. In this
         method, single wall carbon nanotubes are grown by CO
         disproportionation (decomposition into C and carbon dioxide) at
         700-950�in flow of pure CO at a total pressure that typically ranges
         from 1 to 10 atm. This method is based on original work conducted by
         the research group of Prof. Daniel Resasco (currently Chief Scientist
         at SWeNT(TM)) at the University of Oklahoma.
