IN WITNESS WHEREOF, Company and Amdocs, pursuant to due corporate authority, have caused this Agreement to be signed in their respective names on the date(s) set forth below.

In 2009, the Company initiated a broad program to transform its IT infrastructure to better suit the needs of the business.  One component of that transformation was the development and implementation of a new billing and order management system. To that end, the Company entered into a License and Managed Services Agreement with Amdocs, dated as of December 23, 2009, as modified by the First Amending Agreement dated December 22, 2010 (the “License Agreement”), under which Amdocs was to develop and license software and provide enhanced billing and order management services to the Company.

As previously disclosed, we experienced delays and incremental costs during the course of the development and implementation of the new billing and ordering system and the transition of customers to the system. Concurrently, we made significant progress in other areas of our IT transformation, including the enhancement of our existing systems, application stability, improved data analytics to guide our business decision-making, and enhanced capability to quickly solve customer trouble tickets. Substantial improvements were also made to our business environment by upgrading our customer and billing databases. We have also implemented virtualization technology for our IT enterprise applications and cloud computing for our call processing network. The cumulative result of these changes is a substantially improved IT infrastructure. 

We conducted discussions with Amdocs to resolve the issues associated with the billing and ordering system. After these discussions, and after our consideration of the progress made improving our overall IT infrastructure, the incremental time and costs to develop and implement the Amdocs system, as well as the expected reduction in capital expenditures, in June 2012 we and Amdocs determined that terminating the program was in the best interest of both parties. On July 30, 2012, we entered into a Settlement Agreement with Amdocs terminating the License Agreement. As a result, we determined that a write-off of our investment in the system of $25,262,000 net of settlement amounts paid to the Company, was required in the second quarter of 2012. This charge is recorded as loss from abandonment of software assets in the statement of operations. While we did not realize the benefits expected from the new billing and order management system, we believe that the other substantial improvements to our IT infrastructure that have been achieved, in combination with our planned capital expenditures, leaves us well positioned to support our existing and anticipated products and services.

On July 30, 2012, Vonage Network LLC (“Vonage Network”), an indirect, wholly-owned subsidiary of Vonage Holdings Corp. (the “Company”) and Amdocs Software Systems Limited and Amdocs, Inc. (collectively, “Amdocs”) entered into a Settlement Agreement (the “Settlement Agreement”) terminating the parties’ License and Managed Services Agreement dated as of December 23, 2009, as modified by the First Amending Agreement dated December 22, 2010, (as so modified, the “License Agreement”). Under the License Agreement, Amdocs was to develop and license software and provide services to the Company intended to provide enhanced ordering and billing capabilities to better suit the needs of the business. 

The Company experienced delays during the course of development and implementation of the new billing and ordering system and the transition of customers to the system.  After discussions to resolve these issues, the Company and Amdocs concluded that the termination of the project to develop and implement the system was in the best interest of both parties. 

The Settlement Agreement provides for the immediate termination of all services, licenses and obligations pursuant to the License Agreement.  The parties have worked cooperatively to remove Amdocs’ Systems and Software from Vonage’s Systems. The Settlement Agreement further provides that there are no admissions of liability by either party and for mutual releases of all claims arising out of or relating in any way to the License Agreement or to the parties dealings with one another in connection with the License Agreement.  The parties’ confidentiality obligations to each other under the License Agreement survive its termination, and the specific terms of the Settlement Agreement are confidential.  As a result of the termination of the License Agreement, the Company determined that a write-down of its investment in the system of $25,262,000, net of settlement amounts paid to the Company, was required in the second quarter of 2012.  This charge is recorded as a loss from abandonment of software assets in the statement of operations.

Capitalized terms used but not defined herein have the meanings ascribed to them in the Settlement Agreement.  The foregoing description of the Settlement Agreement is qualified in its entirety by reference to the full text of the Settlement Agreement.
