compliant implementation of the referenced IETF RFC 3530. The granting of the
patent license for US 5931913 is contingent upon the grantback of licenses, by

IBM under comparable terms for the compliant implementation of the referenced
RFC (including RFC's 3010, 1813, 1094, and 2339 referenced by RFC 3530).
In the event the licensee / prospective licensee or any of its subsidiaries has
brought or asserts any claim for patent infringement against IBM or any of its
subsidiaries, IBM has the right to unilaterally suspend, terminate, withdraw the
offer or withhold the grant of the license / prospective licensee to the
licensee and its subsidiaries.
