UNDER

Implementation of Change Order NANC 323 in the Canadian Service Area

1. PARTIES

This Statement of Work (this “SOW”) is entered into pursuant to Article 13 and Article 30 of, and upon execution shall be a part of, the Contractor Services Agreement for Number Portability Administration Center/Service Management System (the “Master Agreement”) by and between NeuStar, Inc., a Delaware corporation (“Contractor”) and the Canadian LNP Consortium Inc., a corporation incorporated under the laws of Canada (the “Customer”).

2. EFFECTIVENESS

This SOW shall be effective as of the 1st day of October, 2007 (the “SOW Effective Date”) only upon execution of this SOW by Contractor and Customer. The number in the upper left-hand corner refers to this SOW. Undefined capitalized terms used herein shall have the meanings ascribed by the Master Agreement.

3. ADDITIONAL SERVICES

     3.1 Additional Services

Contractor shall perform the Additional Services set forth herein. The Additional Services under this SOW consist exclusively of the work set forth herein, including without limitation the software development work described in Section 3.2 below (“Software Development Work”), and the work necessary to implement the change order (the “Change Order”) set forth below in Section 3.3, which Change Order Contractor originally incorporated in Release 3.2 of the NPAC/SMS Software (“Release 3.2”) and which Software Development Work Contractor has already performed under this previous software release, and which Change Order currently is implemented in Release 3.3 of the NPAC/SMS Software (“Release 3.3”). The Additional Services under this SOW are an Enhancement to the NPAC/SMS Software as defined in the Master Agreement.

otherwise been made available by Contractor to Customer and Canadian Users, including, for greater certainty, Embedded Functionalities (as defined in SOW 55(CA).

     3.2 Software Development Work

The Software Development Work includes the following activities already performed for other customers of Contractor as of the SOW Effective Date: NPAC/SMS requirements definition; NPAC/SMS system design; NPAC/SMS code and unit test; NPAC/SMS system integration test; NPAC/SMS system and regression test; program management; quality assurance; configuration control and documentation management.

     3.3 Change Order

Contractor shall implement and provide to Customer, in accordance with Article 5 herein, the functionality of the North American Numbering Council (NANC) Change Order set forth below.

NANC 323 — Partial Migration of a SPID via Mass Update

Currently the NPAC does not have the ability to broadcast a mass update on SPID. However, Service Providers need to change the SPID on ported telephone numbers. Examples resulting in this need include mergers, service area trading, and data system consolidations. In order to make a SPID change for given ported telephone numbers, the current NPAC operation requires each involved active-like ported telephone number to be deleted, and each involved pending subscription to be cancelled resulting in a large coordination effort among service providers. Coordination with all service providers utilizing the NPA/NXX is required to facilitate the SPID change. During the transition period, call routing will be affected and customer service is impacted. Once these actions have been taken and the new network data updated at NPAC, the active-like and pending ported telephone numbers information must be re-created. This procedure causes the customer to be out of service during the process and also increases the porting traffic over the interface. This Change Order allows the NPAC to perform a Mass Update of SPID for criteria-based network data and subordinate subscription data. This change order provides this functionality without affecting the customer while reducing porting traffic over the interface.

     3.4 Acceptance

If not accepted sooner by Customer, the Additional Services shall be deemed to have been accepted (“Acceptance”) upon the absence of Critical Defects (as defined herein) in the Change Order functionality implemented hereunder as of thirty (30) days after the SOW Completion Date. For purposes of this Section 3.4, a “Critical Defect” shall mean

any functional defect in the Canadian NPAC/SMS that prevents one or more Users from performing a create, activate, modify, or delete of a ported number record. The Critical Defect must be reproducible by Customer and Contractor, and one for which no acceptable alternative functionality can be identified.

4. OUT OF SCOPE SERVICES

The Additional Services provided for in this SOW shall not be interpreted, implied, or assumed to include any other service(s) (hereinafter “Out of Scope Services"), which Out of Scope Services shall be provided in accordance with the Master Agreement and, specifically, Article 13, Additional Services.
