WHEREAS, in connection therewith, Recipient desires that Provider provide, and Provider is willing to provide to Recipient, certain services during the term of this Agreement as provided herein; and

NOW, THEREFORE, in consideration of the foregoing premises, and the mutual covenants of the parties hereinafter set forth, Recipient and Provider hereby agree as follows:

1.                                       Services to be Rendered.  From and after the date hereof until this Agreement expires or terminates in accordance with Section 8 hereof, Provider shall provide management consultancy services to Recipient and the Subs. Such management consultancy services, including the integration activities described in Section 1(b) below (the “Integration Services”), are referred to herein as the “Management Consultancy Services” and shall be as more fully set out in Sections 1(a) and 1(b).

(a)                                  Provider shall provide the services set out in Schedule 1 hereto to Recipient and Subs.  It shall also provide advice, support and assistance to the boards of directors (which term, for the purposes of this Agreement, in relation to entities which are not English companies, shall be deemed to include all bodies and boards constituted in relation to those entities with

analogous or similar rights and duties) of Recipient and the Subs in relation to (i) the management of the business and business relationships of the Subs, including maintaining relationships with, providing services to or receiving services from and making payments to and receiving payments from customers, vendors, suppliers and other persons with whom the Subs do business, (ii) continuing the operations of Recipient’s and the Subs’ network, facilities, “back office” operations and technical personnel, (iii) overseeing the Subs’ sales force, distributors, marketing and similar matters, and (iv) continuing the other aspects of the Subs’ business and operations.  Provider shall provide such personnel as are necessary in order to properly conduct and provide the Management Consultancy Services.  In performing the Management Consultancy Services, Provider shall give consideration as to whether it would be appropriate for the Subs or any of them to enter into new or amended business arrangements with customers, vendors, suppliers and other persons with whom such entity does business (always having regard to the importance of maintaining the Subs’ business and relationships in good and proper standing in the ordinary course).  Provider shall also give consideration as to whether it would be appropriate for the Subs or any of them to outsource any part of Recipient’s or the Subs’ business operations to Provider or another third party provider pursuant to a written contract on commercially reasonable terms and conditions.

(b)                                 Provider shall provide advice, support and assistance in relation to the actions required to reconfigure circuits and other network components; restructure “back office” operations; hire, reassign, or terminate employees and contractors; amend or otherwise alter customer agreements on behalf of a Sub as it considers reasonably necessary or desirable to reduce operating costs of Recipient or the Subs.  In anticipation of the completion of the Purchase Agreement, Provider shall provide advice, support and assistance in relation to the actions required to make Recipient’s operations function more efficiently in conjunction with those of Provider whilst maintaining all existing critical or significant functions and the level of Recipient’s business and its customer relationships in good and proper standing in the ordinary course.

(c)                                  For the avoidance of doubt, in performing Management Consultancy Services hereunder, Provider shall have no authority to make any decisions or take any action for and on behalf of Recipient or any Sub or to otherwise bind or commit Recipient or any Sub.

2.                                       Standards.  Provider shall provide the Management Consultancy Services in accordance with standards, practices, methods and procedures conforming with (a) all applicable laws and regulations, (b) the degree of care, skill, diligence, prudence and foresight which Provider employs in managing its own business (which shall not be less than reasonable care).  In providing the Management Consultancy Services, Provider shall at all times act in good faith and shall have regard to Recipient’s overriding objectives to (i) preserve the goodwill, customers and business relationships of the Subs, and (ii) prevent any creditor of a Sub from filing an involuntary petition in bankruptcy or a petition seeking reorganization, composition, arrangement with creditors, liquidation or similar relief under any federal or state law or regulation with respect to a Sub, or appointing a receiver, trustee or liquidator for all or a substantial part of the assets of any Sub.

3.                                       Payment for Management Consultancy Services.
