(formerly named Viper US MergerCo 1 Corp.), a Colorado corporation (the “Company”), Liberty Global plc, a U.K. public limited company (“Liberty Global”), and The Bank of New York Mellon, a New York banking corporation, as trustee (the “Trustee”).

WHEREAS, Virgin Media Inc. (“VMI”), the predecessor of the Company, and the Trustee entered into the Indenture, dated as of April 16, 2008 (the “Original Indenture”), pursuant to which VMI issued the Securities;

WHEREAS, the Company, Liberty Global and the Trustee entered into the Supplemental Indenture, dated as of June 7, 2013 (the “Supplemental Indenture”), which amended and supplemented the Original Indenture (the Original Indenture, as amended and supplemented by the Supplemental Indenture, the “Amended Indenture”), in connection with a series of mergers contemplated by an Agreement and Plan of Merger, dated as of February 5, 2013, among VMI, Liberty Global and the other parties thereto pursuant to which VMI underwent a merger (the “Merger”), as a result of which the Company became (i) the successor to VMI in accordance with Article 8 of the Original Indenture and (ii) the “Company” for all purposes of the Amended Indenture;

WHEREAS, as a result of the Merger, the right of Holders of Securities to convert each $1,000 principal amount of Securities was changed to a right to convert such Securities by reference to the Reference Property that a holder of a number of shares of Common Stock equal to the Conversion Rate immediately prior to the Merger would be entitled to receive in the Merger;

WHEREAS, on the date hereof the constitution of the Reference Property is 13.4339 Class A Shares, 10.0312 Class C Shares and $910.51 in cash (without interest);

WHEREAS, pursuant to Section 12.04(m) of the Amended Indenture, if Liberty Global takes any action of the type described in Section 12.04 of the Amended Indenture with respect to the Class A Shares or Class C Shares, which, in either case, if taken with respect to the Common Stock would have required an adjustment to the Conversion Rate, then the Company shall effect an adjustment to the number of Class A Shares or Class C Shares, as the case may be, included in the Reference Property so as to approximate, in the reasonable judgment of the Board of Directors, the adjustment contemplated by Section 12.04 of the Amended Indenture;

WHEREAS, Liberty Global has declared a share dividend of one Class C Share for each outstanding Class A Share, Class C Share and Class B Ordinary Share, nominal value $0.01 per share, of Liberty Global, held of record as of the close of business on February 14, 2014 (the “Class C Dividend”);

WHEREAS, the Ex date for the Class C Dividend will be March 4, 2014 (the “Class C Dividend Ex Date”);

WHEREAS, in accordance with Section 12.04(m) of the Amended Indenture, the Company has determined to adjust the constitution of the Reference Property, as a result of the Class C Dividend, to be 13.4339 Class A Shares, 33.4963 Class C Shares and $910.51 in cash (without interest), such adjustment to become effective as of the opening of business on the date that is immediately after the Class C Dividend Ex Date;

WHEREAS, the foregoing adjustment to the constitution of the Reference Property approximates, in the reasonable judgment of the Board of Directors, the adjustment contemplated by Section 12.04 of the Amended Indenture, taking into account the other provisions of Section 12.04;

WHEREAS, the foregoing adjustment to the constitution of the Reference Property requires amendments to certain definitions which are based upon the constitution of the Reference Property;

WHEREAS, the Company, Liberty Global and the Trustee are entering into this Second Supplemental Indenture to effect the foregoing adjustments and amendments and to add additional provisions to the Indenture that will obviate the need in the future to execute a further supplemental indenture in connection with certain ordinary course share

transactions which require, in accordance with Section 12.04(m) of the Indenture, an adjustment to the Reference Property that increases (but does not decrease) one or more components of the Reference Property;

WHEREAS, Section 9.01 of the Amended Indenture provides that the Company, when authorized by a Board Resolution, and the Trustee may enter into a supplemental indenture, without the consent of any Holders: (i) pursuant to clause (a) of Section 9.01, to cure any ambiguity, manifest error, defect or omission or inconsistency, (ii) pursuant to clause (i) of Section 9.01, to make provision with respect to the conversion rights of Holders pursuant to the requirements of Article 12 of the Amended Indenture; and (iii) pursuant to clause (j) of Section 9.01, to make any change that does not adversely affect the rights of any Holder in any material respect;

WHEREAS, the Company and Liberty Global are entering into this Second Supplemental Indenture in accordance with Section 9.01(a), (i) and (j) of the Original Indenture (the Amended Indenture, as amended and supplemented by this Second Supplemental Indenture, is referred to herein as the “Indenture”); and

WHEREAS, all requirements necessary to make this Second Supplemental Indenture a valid, binding and enforceable instrument in accordance with its terms have been done and performed, and the execution and delivery of this Second Supplemental Indenture has been duly authorized in all respects.

NOW, THEREFORE, in consideration of the premises hereof, the parties have executed and delivered this Second Supplemental Indenture, and the Company, Liberty Global and the Trustee agree for the benefit of each other and for the equal and ratable benefit of the Holders, as follows:

Any capitalized term used and not otherwise defined herein shall have the meaning assigned to such term in the Indenture.

Any such determination shall be conclusive absent manifest error.

(b)    Section 12.04 of the Amended Indenture is amended by inserting the following paragraph (n) at the end thereof:

“(n) In the event the Reference Property is adjusted, pursuant to Section 12.04(m) of the Indenture due to an action involving the Class A Shares or the Class C Shares (or both) of the type described in subsections (a) or (b) of Section 12.04 of the Indenture, to increase one or more components of the Reference Property, the Company shall deliver the required Officer’s Certificate and Opinion of Counsel in connection therewith and no Supplemental Indenture shall be required to effect such adjustment. Such Officer’s Certificate shall set forth all the adjustments made to any definitions included in the Indenture that are based on the constitution of the Reference Property, including but not limited to the terms “Daily Conversion Value,” “Reference Property Daily VWAP,” and “Reference Property Value,” in full text and the Indenture shall be deemed to be amended, mutatis mutandis, to give effect to such adjustment for each such future calculation made by the Company and set forth in such Officer's Certificate. If the Company is required to make any adjustment to one or more components of the Reference Property following an action involving the Class A Shares or the Class C Shares (or both) of the type described in subsections (a) or (b) of Section 12.04 of the Indenture that decreases one or more components of the Reference Property, those adjustments shall be made in a Supplemental Indenture entered into in accordance with the requirements of Article 9 of the Indenture. Any and all adjustments of the Reference Property that are required to be made due to an action involving the Class A Shares or the Class C Shares (or both) of the type described in subsections (c), (d) or (e) of Section 12.04 of the Indenture shall also be evidenced by Supplemental Indenture entered into in accordance with Article 9 of the Indenture.”
