A Grant of Rights to Use IBM US Patent 5,148,479

IBM hereby covenants that it will not assert its US Patent 5,148,479
or its non-US counterparts against any party that implements Photuris
or any derivative that includes IBM's IKMP contribution, and operates
in compliance with Photuris or such derivative, when Photuris or such
derivative is employed in connection with any Internet Protocol.

This grant of rights will terminate with respect to any party that
asserts a patent it owns, directly or indirectly, against IBM for
IBM's implementation of and operation in compliance with Photuris or
any derivative, as defined above. The termination will occur as of
the date the patent is asserted against IBM.

A written confirmation of this grant, and/or a license under any
other IBM patent under IBM's then-current terms, conditions and
royalty rates, can be obtained by sending a request to:
