(No information submitted)

Licensing information, comments, notes, or URL for further information

To the extent that the reference in IV., supra, is incorporated in an IETF RFC, Certicom informs that it
and its Affiliates will make a license available on fair, reasonable and non‐discriminatory ("FRAND")
terms and conditions based on reciprocity to all persons desiring to implement such IETF RFC for those
claims of the Disclosed Patents only that would, in the absence of a license, be necessarily infringed by
the use of a right (e.g. making, using, selling, importing, distribution, copying, etc) with respect to a
technology implementing such IETF RFC (the "License"). In this context, "necessarily infringed" means
that such claims are technically necessary to implement the IETF RFC in question.
“Affiliate” of Certicom Corp. means any legal entity that is for the time being directly or indirectly in
control of or controlled by Certicom Corp.  Control in this context, exists where one entity owns more
than fifty percent (50%) of the voting stock or equity in another entity, or regardless of stock or equity
ownership, is otherwise able to direct its affairs or to appoint a majority of the members of the board of
directors or an equivalent body to determine the course of action of the entity by virtue of its voting or
other rights. Such entities shall only be deemed to be Affiliates, hereunder for as long as such control

Note: The individual submitting this template represents and warrants that he or she is authorized by the Patent Holder to agree to the above-selected licensing declaration.
