For purposes of the exercise of any rights granted to Shareholder under the SRA and any notice required or permitted to be given by Shareholder pursuant to the SRA, such exercise of rights or notice given by Everitt individually shall suffice as being effected by the Assignees.

3. Amendments to the SRA. The Assignees and CenturyLink hereby agree that the SRA shall be amended as follows with effect from the Stock Transfer Date:

(i) Section 1(a) of the SRA shall be amended and restated in its entirety to read as follows:

““Affiliate” shall mean, (i) with respect to the Shareholder, any entity within the T+I Group, it being understood that for so long as an information wall is maintained between the T+I Group (as defined below) and the Temasek Portfolio Companies (as defined below), any shares of Common Stock Beneficially Owned by a Temasek Portfolio Company shall not be considered to be Beneficially Owned by any entity within the T+I Group; and (ii) with respect to (x) any other Person and (y) the Shareholder, if it fails to maintain an information wall as described above in clause (i) of this definition, any other Person directly or indirectly controlling or controlled by or under direct or indirect common control with such Person. For purposes of this definition:

(1) “control” when used with respect to any Person has the meaning specified in Rule 12b-2 under the Exchange Act; and the terms “controlling” and “controlled” have meanings correlative to the foregoing;

(2) “T+I Group” refers to Temasek Holdings (Private) Limited and its investment holding companies, being its direct and indirect wholly-owned subsidiaries whose boards of directors or equivalent governing bodies comprise employees or nominees of (a) Temasek Holdings (Private) Limited, (b) Temasek Pte. Ltd., a wholly-owned subsidiary of Temasek Holdings (Private) Limited, and/or (c) wholly-owned subsidiaries of Temasek Pte. Ltd. The principal activities of Temasek Holdings (Private) Limited and its investment holdings companies described above are that of investment holding, financing and/or the provision of investment advisory and consultancy services; and

(3) “Temasek Portfolio Companies” refers to entities in which Temasek Holdings (Private) Limited holds, directly and/or indirectly, an interest, other than entities within the T+I Group.”

(ii) Section 4.2 of the SRA shall be amended to include the following language at the end of the provision:

“so long as each such Affiliate agrees in writing to assume all of Assignor’s obligations under and agrees to be bound by the provisions of this Agreement”.

(iii) Section 5.12(ii) of the SRA shall be amended to include the following proviso language at the end of the provision:

“provided, however, the Shareholder shall not be subject to such Insider Trading Policy for so long as the Shareholder maintains an information wall between itself and the Shareholder Employee Director that is designed to prevent the flow of information relating to Parent from the Shareholder Employee Director to the Shareholder”.

(iv) Section 9.4(c) of the SRA shall be amended and restated in its entirety to read as follows:
