The Parties further agree that GENBAND expressly retains all rights, privileges, duties and obligations under the

106

Nortel IPLA regarding the Licensed Signaling Gateway IP that GENBAND is permitted to retain pursuant to Section 4.05(a)(4)(x), (y) and (z) therein.

2.02          Licensed Intellectual Property.  Subject to the terms and conditions of this License Agreement, GENBAND hereby grants to PT a perpetual, irrevocable (except as specifically provided in Section 5.02), non-sublicensable (except as specifically provided in Section 2.06), non-exclusive, worldwide, royalty-free, fully paid-up license (or sublicense, as applicable): (i) under the GENBAND Signaling Gateway IP (other than any Patents) to use, distribute, display and publish, copy, create Derivative Works of, modify, and otherwise commercially exploit such GENBAND Signaling Gateway IP (other than Patents), in each case solely in connection with products and services within the Field of Use, and (ii) under the GENBAND Signaling Gateway Patents, to make, develop, use, lease, sell, offer for sale, import, support, service, and otherwise dispose of products and services and practice any methods in connection therewith, in each case solely within the Field of Use.  The licenses granted under this Section 2.02 also include Integration Rights in connection with products and services within the Field of Use.

2.04          Hardware Integration.  GENBAND agrees that it will not assert any Signaling Gateway IP or any Signaling Gateway Patents against any PT hardware product containing

2.12          Reservation of Rights.  GENBAND reserves all rights and licenses not expressly granted in this License Agreement, and, except to the extent solely necessary to permit PT to use, manufacture, distribute and support the Signaling Gateway Product Line, nothing in this License Agreement shall be construed as implying or give rise to any implied grant or license of any right not expressly set forth in this License Agreement.  For the avoidance of doubt, the Parties expressly agree that GENBAND shall maintain the right to re-use the graphical user-interface source code associated with the Universal Signaling Point product for use in GENBAND solutions of a non-signaling nature and which are unrelated to the Signaling Gateway Product Line.

term or condition, of this License Agreement.  The failure or delay by any Party to assert any of its rights under this License Agreement or otherwise shall not constitute a waiver of such rights nor shall any single or partial exercise by any Party of any of its rights under this License Agreement preclude any other or further exercise of such rights or any other rights under this License Agreement.

5.09          Enforcement.  The Parties agree that irreparable damage would occur in the event that any of the provisions of this License Agreement were not performed in accordance with their specific terms or were otherwise breached.  It is accordingly agreed that the Parties shall be entitled to seek an injunction or injunctions to prevent breaches of this License Agreement and to enforce specifically the terms and provisions of this License Agreement in the Delaware Court of Chancery (and if the Delaware Court of Chancery shall be unavailable, in any Delaware State court or the Federal court of the United States of America sitting in the State of Delaware), this being in addition to any other remedy to which they are entitled at law or in equity.

5.10          Entire Agreement.  This License Agreement and the ASA constitute the entire agreement, and supersede all prior agreements and understandings, both written and oral, among the Parties with respect to the subject matter of this License Agreement.

5.11          GOVERNING LAW.  THIS LICENSE AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF DELAWARE, REGARDLESS OF THE LAWS THAT MIGHT OTHERWISE GOVERN UNDER APPLICABLE PRINCIPLES OF CONFLICTS OF LAWS THEREOF. 

5.12          Consent to Jurisdiction.  Each of the Parties irrevocably and unconditionally submits to the exclusive jurisdiction of the Delaware Court of Chancery (and if the Delaware Court of Chancery shall be unavailable, any Delaware State court and the Federal court of the United States of America sitting in the State of Delaware) for the purposes of any matters or claims arising out of this License Agreement or any transaction contemplated hereby (“Litigation”) (and each agrees that no such Litigation shall be brought by it or any of its Affiliates except in such courts).  Each of the Parties further agrees that, to the fullest extent permitted by applicable law, service of any process, summons, notice or document by U.S. registered mail to such Person’s respective address set forth in Section 5.01 shall be effective service of process for any Litigation in Delaware with respect to any matters to which it has submitted to jurisdiction as set forth above in the immediately preceding sentence.  Each of the Parties irrevocably and unconditionally waives (and agrees not to plead or claim) any objection to the laying of venue of any Litigation in the Delaware Court of Chancery (and if the Delaware Court of Chancery shall be unavailable, in any Delaware State court or the Federal court of the United States of America sitting in the State of Delaware) or that any such Litigation brought in any such court has been brought in an inconvenient forum.

5.13          WAIVER OF JURY TRIAL.  EACH PARTY HEREBY WAIVES, TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, ANY RIGHT IT MAY HAVE TO A

115

TRIAL BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF, UNDER OR IN CONNECTION WITH THIS AGREEMENT.  EACH PARTY (A) CERTIFIES THAT NO REPRESENTATIVE, AGENT OR ATTORNEY OF ANY OTHER PARTY HAS REPRESENTED, EXPRESSLY OR OTHERWISE, THAT SUCH PARTY WOULD NOT, IN THE EVENT OF ANY LITIGATION, SEEK TO ENFORCE THE FOREGOING WAIVER AND (B) ACKNOWLEDGES THAT IT AND THE OTHER PARTIES HERETO HAVE BEEN INDUCED TO ENTER INTO THIS AGREEMENT BY, AMONG OTHER THINGS, THE MUTUAL WAIVER AND CERTIFICATIONS IN THIS SECTION 5.12.

5.14          Counterparts.  This Agreement may be executed in one or more counterparts, all of which shall be considered one and the same agreement and shall become effective when one or more counterparts have been signed by each of the Parties and delivered to the other Parties.  If any signature is delivered by facsimile transmission or by PDF, such signature shall create a valid and binding obligation of the Party executing (or on whose behalf the signature is executed) with the same force and effect as if such facsimile or PDF signature were an original thereof.
