Ladies and Gentlemen:

The Underwriting Agreement provides for the sale to the Underwriters, and the purchase by the Underwriters, severally and not jointly, from the Company, subject to the terms and conditions set forth therein, of $750,000,000 aggregate principal amount of the Company’s 6.125% Notes due 2053 (the “Initial Securities”) to be issued pursuant to an Indenture dated as of October 15, 1999, between the Company (formerly named US WEST Communications, Inc.) and Bank of New York Trust Company, National Association (as successor in interest to Bank One Trust Company and J.P. Morgan Trust Company, National Association), as amended and supplemented to the date hereof, and as will be further supplemented by the Twelfth Supplemental Indenture between the Company and U.S. Bank National Association, as trustee, to be dated as of May 23, 2013 relating to the Securities (as defined herein). This Agreement is the Price Determination Agreement referred to in the Underwriting Agreement.

For all purposes of the Underwriting Agreement, “Time of Sale” means 3:50 p.m. (New York City time) on the date of this Price Determination Agreement.

Pursuant to Section 1(b) of the Underwriting Agreement, the undersigned agree with the several Underwriters that the purchase price for the Initial Securities to be paid by the several Underwriters shall be 96.85% of the aggregate principal amount of the Initial Securities set forth opposite the names of the Underwriters in Schedule I attached thereto for retail orders (aggregating to a $573,230,938 purchase price in respect of $591,875,000 aggregate principal amount of such orders); provided that such purchase price will be 98.00% of the aggregate principal amount of the Securities sold by the Underwriters to certain institutions (aggregating to a $154,962,500 purchase price in respect of $158,125,000 aggregate principal amount of such sales). In addition, pursuant to Section 1(c) of the Underwriting Agreement, the Company hereby grants to the Underwriters an option to purchase up to an additional $25,000,000 aggregate principal amount of the Company’s 6.125% Notes due 2053 (the “Option Securities” and, together with the Initial Securities, the “Securities”) at a purchase price of 96.85% of the aggregate principal amount of such Option Securities.

The Company represents and warrants to the several Underwriters that the representations and warranties of the Company set forth in Section 3 of the Underwriting Agreement are accurate as though expressly made at and as of the date hereof.

THE RIGHTS AND DUTIES OF THE PARTIES TO THIS PRICE DETERMINATION AGREEMENT SHALL, PURSUANT TO NEW YORK GENERAL OBLIGATIONS LAW SECTION 5-1401, BE GOVERNED BY THE LAW OF THE STATE OF NEW YORK WITHOUT REGARD TO ANY CHOICE OF LAW PRINCIPLES THAT MIGHT CALL FOR THE APPLICATION OF THE LAW OF ANY OTHER JURISDICTION.
