applications of NTRU Cryptosystems, NTRU Cryptosystems agrees upon request 
to grant a non-exclusive license under such patent or patents or 
applications on a non-discriminatory basis and on reasonable terms and

grant under the licensee's patents under the scope of the license granted 
to licensee is made available upon request to NTRU Cryptosystems.
