(identified in section V above) that may relate to RFC 3603. To the extent that
the technology discussed in the above referenced IETF document(s) becomes an
IETF Standard, and to the extent claims of AT&T's patents are required to

offer, on a nondiscriminatory basis, non-exclusive licenses on fair and
reasonable terms under such patent claims to implement that IETF Standard.
AT&T's willingness to grant such licenses is conditioned upon the prospective
licensee granting a reciprocal license to AT&T under any patents that the
prospective licensee has to any technology required to implement that IETF
Standard.
