Mr. Mark Schweitzer

[Address Intentionally Omitted]

Reference is made to the employment agreement, dated as of September 18, 2007, between you and Virgin Media Inc., as amended (the “Employment Agreement”).

In consideration of the mutual covenants contained herein, and other good and valuable consideration, including without limitation, the grant of options and restricted stock units under the Company’s 2009 LTIP, receipt and sufficiency of which is hereby acknowledged, the parties hereto agree that the terms of the Employment Agreement will remain in effect in all respects, except as follows:

1. Bonus

Section 3(b)(i) of the Employment Agreement shall be amended and replaced in its entirety by the following paragraphs:

“(b) Annual Bonus/Other.

(i)(x) During each fiscal year of the Company that the Employment Term is in effect, the Executive shall be eligible to earn a bonus in the sole discretion of the Board pursuant to the terms of the Company’s Executive Bonus Scheme, in cash, shares (restricted or otherwise) of the Company, or options or phantom options over such shares or a mixture thereof at the discretion of the Company’s Compensation Committee, in the expected range of 0% to 150% (75% on-target), prorated for any partial calendar year (the “Annual Bonus”). The Executive shall be entitled to participate in the Company’s 2008/2010 Long Term Incentive Plan (LTIP), as may be amended from time to time. The LTIP is a discretionary Company scheme. The Executive may elect to receive all or any portion of the cash bonus or cash LTIP payment, if any, in U.S. dollars, subject to the Company’s Exchange Rate Policy in effect from time to time.

(y) If the Company’s Compensation Committee determines that the Executive’s gross negligence, fraud or other misconduct has contributed to the any member of the Company Affiliated Group having to restate all or a portion of its financial statements, the Company’s Compensation Committee may if it determines in its sole judgment that it is in the Company Affiliated Group ‘s interest to do so, require reimbursement by the Executive of any payment made under any bonus scheme where: (1) the payment under that bonus scheme was predicated upon achieving certain financial results that were subsequently the subject of a restatement of financial statements of any member of the Company Affiliated Group filed with the Securities and Exchange Commission and/or the satisfaction of financial results or other performance metric criteria which the Company’s Compensation Committee subsequently determined were materially inaccurate; (2) the Company’s Compensation Committee determines that the Executive’s gross negligence, fraud or other misconduct contributed to the need for the restatement and/or inaccuracy; and (3) a lower bonus payment or award would have been made to the Executive based upon the restated financial results or accurate financial results or performance metric criteria. In any such case the Company’s Compensation Committee may, to the extent permitted by applicable law, recover from the Executive, whether or not he remains in employment with the Company Affiliated Group, the amount by which the Executive’s bonus payment or award for the relevant period exceeded the lower payment or award, if any, that would have been made based on the restated financial results or accurate financial results or performance metric criteria. The Executive agrees that he will upon demand by any member of the Company Affiliated Group repay to the Company Affiliated

Group the sum so demanded within 21 days of receiving the demand for payment and whether or not he remains the employee of the Company Affiliated Group together with interest whichever is the greater of 5% or 1% above the Bank of England minimum lending rate from time to time from the date of the bonus payment or award to the date of actual repayment.”

All references in the Employment Agreement to “Annual Cash Bonus” or “annual cash bonus” shall be replaced with the terms “Annual Bonus” or “annual bonus”, respectively.

2. Release Agreement

Appendix C of the Employment Agreement shall be amended and replaced in its entirety as set forth on Exhibit A.

This letter confirms our understanding on these matters and your Employment Agreement with the Company is amended in accordance with the foregoing. Terms used but not defined in this letter shall have the meaning of such terms as defined in your Employment Agreement.

This letter shall be governed by and construed in accordance with the internal laws of the State of New York (without regard, to the extent permitted by law, to any conflict of law rules which might result in the application of laws of any other jurisdiction).

	Sincerely,

	VIRGIN MEDIA INC.
