Licensing Declaration: If the standard reference in IV., supra, is adopted, Certicom Corp. will, upon request and after providing a written confirmation of the terms herein, provide a non-exclusive, royalty-free patent license, to permit end users (including both client and server sides), to use such essential patents owned by Certicom Corp. when implementing the above specification subject to the following limitations and provided that the following conditions are met in full: 1. Certicom Corp. retains the right to assert any of its patents (including the right to claim past royalties) against any party that asserts a patent it owns or controls (either directly or indirectly) against Certicom Corp., and/or any of Certicom's Affiliates or successors in title (collectively "Certicom"). If any such assertion is made against Certicom, then a material term of this license has not been met and any purported previous license pursuant to this declaration is revoked and shall be treated as if it never existed; Certicom retains the right to assert any of its patents (including the right to claim past royalties) against any party that asserts a patent it owns or controls (either directly or indirectly) against a Certicom product or service, either alone or in combination with other products or services. If any such assertion is made against a Certicom product or service, then a material term of this license has not been met and any purported previous license pursuant to this declaration is revoked and shall be treated as if it never existed; 2. Certicom retains the right to assert its patents against any product, service or portion thereof that is not essential to elements of the above specification. 3. Any public keys utilized in an implementation of ECPVS according to this IETF specification are extracted from a certificate issued from a Certicom-licensed Certificate Authority ("CA"); and 4. The party requesting a license must provide reciprocal licensing terms to Certicom for all Certicom products and services. The license granted does not extend, either explicitly or implicitly, to any protocol other than that referenced in IV., supra. If any party does not agree to all of the above terms, Certicom will also negotiate a license to the essential Certicom patents under FRAND terms subject to reciprocity and defensive suspension. "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 exists. VII. Contact Information of Submitter of this Form David Lewis, 1-905-501-3771, dlewis@certicom.com
