Mr. Jacques Kerrest

c/o Virgin Media Inc.

909 Third Avenue

New York, New York 10022

Dear Jacques:

As we have discussed, we are pleased to extend the term of your Employment Agreement as described below.  The terms of your Employment Agreement will remain in effect in all respects, except as follows:

1.                                                              Assignment to new Virgin Media Inc.

As a result of the merger with Telewest Global, Inc. being structured as a reverse acquisition, the former NTL Incorporated changed its name to NTL Holdings Inc. and subsequently changed its name to Virgin Media Holdings Inc. (“Old NTL”) and the former Telewest changed its name to NTL Incorporated and subsequently changed its name to Virgin Media Inc. (the “Company”).  We agree that your Employment Agreement with Old NTL shall be assigned to and assumed by the Company and in this connection:

(i)                                   all references to the “Company” in the Employment Agreement now refer to the Company instead of Old NTL;

(ii)                                all obligations of Old NTL under the Employment Agreement are assumed by the Company, and all claims that you may have against Old NTL or the Company shall be asserted solely against the Company; and

(iii)                             all obligations of the Executive owed to Old NTL or the Company under the Employment Agreement shall be enforceable against the Executive by the Company.

2.                                                              Extension

(a)                                                          Notwithstanding anything to the contrary in Section 7 of the Employment Agreement, the Executive’s Employment Term is extended to December 31, 2008; provided, however, on or after March 31, 2008, upon a Termination Without Cause, a Constructive Termination Without Cause or a Termination upon Non-Renewal, the Company shall, within 90 days after the date of such Termination, provided that the Executive executes and delivers to the Company the general release of claims set forth in Section 7(e) of the Employment Agreement (the “Release”) and, the Executive does not revoke the

Release prior to the expiration of any applicable revocation period, cause the Executive to be paid a lump-sum severance payment of cash (the “Severance Payment Amount”) equal to fifteen calendar months of Base Salary.

(b)                                                         At any time on or after March 1, 2008, the Executive may terminate his employment on 30 days’ written notice to the Company and the Company shall, within 90 days after the date of such termination, provided that the Executive executes and delivers to the Company the Release and, the Executive does not revoke the Release prior to the expiration of any applicable revocation period, cause the Executive to be paid the Severance Payment Amount.

(c)                                                          The Company shall, in its discretion, determine the exact date of payment of the severance amounts described in (a) and (b) above.

3.                                                              Expatriate Package

The following paragraph shall be added to the end of Section 3(c) of the Employment Agreement:

Any such reimbursement shall be made in accordance with the Company’s Tax Equalization Policy, but shall be made not later than the end of the second taxable year of Executive beginning after the later of (i) the taxable year of Executive in which Executive’s U.S. federal income tax return is required to be filed (including any extensions), reflecting the compensation for which the tax equalization payment is provided, or (ii) the taxable year of Executive in which Executive’s foreign tax return or payment is required to be filed or made, reflecting the compensation for which the tax utilization payment is provided.

4.                                                              Section 409A and 280G

The following paragraphs shall be added as Sections 7(h) and (i) to the Employment Agreement:

(h)                                                         Effect of Section 409A of the Internal Revenue Code.  If the Executive is a “specified employee” on the date of termination of the Executive’s employment for purposes of Section 409A of the Internal Revenue Code of 1986, as amended, and the regulations thereunder (the “Code”), notwithstanding any provision of the Agreement relating to the timing of payments to the Executive hereunder, if Section 409A would cause the imposition of the additional tax under Section 409A if paid as provided in Section 7 of the Agreement, then as much of the severance payment as may be paid without the imposition of the additional tax shall be paid in a lump sum as aforesaid, and any remaining portion of the severance payment shall be paid upon the day following the six-month anniversary of the date of termination.   For purposes of this Agreement, “Specified Employee” shall mean a “specified employee” within the meaning of Code section 409A(a)(2)(B)(i), as determined by the Company’s Compensation Committee.

(i)                                                           Effect of Section 280G of the Internal Revenue Code.  (i) Anything in this Agreement to the contrary notwithstanding, in the event that it is determined by the Company and its US tax advisors that any payment (other than the Gross-Up Payments (as defined below) provided for in this Section 7) or distribution by the Company or any of its affiliates to or for the benefit of the Executive, whether paid or payable or distributed or distributable pursuant to the terms of this Agreement or otherwise pursuant to or by reason of any other agreement, policy, plan, program or arrangement, including, without limitation, any stock option, performance share, performance unit, stock appreciation right or similar right, or the lapse or termination of any restriction on or the vesting or exercisability of any of the foregoing (a “Payment”), would be subject to the excise tax imposed by Section 4999 of the Code (or any successor provision thereto), by reason of being considered “contingent on a change in ownership or control” of the Company, within the meaning of Section 280G of the Code (or any successor provision thereto) or to any similar tax imposed by state or local law, or any interest or penalties with respect to such tax (such tax or taxes, together with any such interest and penalties, being hereinafter collectively referred to as the “Excise Tax”), then the Executive will be entitled to receive an additional payment or payments (collectively, a “Gross-Up Payment”).  The Gross-Up Payment will be in an amount such that, after payment by the Executive of all taxes (including any interest or penalties imposed with respect to such taxes), including any Excise Tax imposed upon the Gross-Up Payment, the Executive retains an amount of the Gross-Up Payment equal to the Excise Tax imposed upon the Payment.  For purposes of determining the amount of the Gross-Up Payment, the Executive will be considered to pay (x) federal income taxes at the highest rate in effect in the year in which the Gross-Up Payment will be made and (y) state and local income taxes at the highest rate in effect in the state or locality in which the Gross-Up Payment would be subject to state or local tax, net of the maximum reduction in federal income tax that could be obtained from deduction of such state and local taxes.  Any Gross-Up Payment shall be paid by the Company to the Executive at the same time as the associated Payment, or as soon thereafter as is practical, but in all cases, within 25 days of the receipt of notice from the Executive that there has been a Payment.  As a result of the uncertainty in the application of Section 4999 of the Code at the time of the initial determination of the Company, it is possible that Gross-Up Payments which will not have been made by the Company should have been made (“Underpayment”).  In the event the Company exhausts or does not seek to pursue its remedies pursuant to Section 7(i)(ii) and the Executive thereafter is required to make a payment of any Excise Tax, the Company and its US tax advisors, or at the Executive’s election and expense, a nationally recognized accounting firm to be appointed by the Executive, shall determine the amount of Underpayment that has occurred.  If the Executive elects to have a nationally recognized accounting firm determine the amount of any Underpayment, detailed supporting calculations of such determination shall be provided to the Company.  Any such Underpayment shall be paid by the Company to or for the benefit of the Executive as promptly as practicable.

(ii)                                                        Executive shall notify the Company in writing of any claim by the Internal Revenue Service that, if successful, would require the payment by the Company of the Gross-Up Payment.  Such notification shall be given as soon as practicable but no later than ten (10) business days after Executive is informed in writing of such claim and shall apprise the Company of the nature of the claim and the date on which such claim is requested to be paid.  Executive shall not pay such claim prior to the expiration of the 30-day period following the date on which he gives such notice to the Company (or such shorter period ending on the date that any payment of taxes with respect to such claim is due).  If the Company notifies Executive in writing prior to the expiration of such period that it desires to contest such claim, Executive shall:

(a)                                                        give the Company any information reasonably requested by the Company relating to such claim,

(b)                                                       take such action in connection with contesting such claim as the Company shall reasonably request in writing from time to time, including, without limitation, accepting legal representation with respect to such claim by an attorney reasonably selected by the Company,

(c)                                                        cooperate with the Company in good faith in order effectively to contest such claim, and

(d)                                                       permit the Company to participate in any proceedings relating to such claim; provided, however, that the Company shall bear and pay directly all costs and expenses (including additional interest and penalties) incurred in connection with such contest and shall indemnify and hold Executive harmless, on an after-tax basis, for any Excise Tax or income tax (including interest and penalties with respect thereto) imposed as a result of such representation and payment of costs and expenses. Without limitation on the foregoing provisions of this Section 7(i)(ii), the Company shall control all proceedings taken in connection with such contest and, at its sole option, may pursue or forgo any and all administrative appeals, proceedings, hearings and conferences with the taxing authority in respect of such claim and may, at its sole option, either direct Executive to pay the tax claimed and sue for a refund or to contest the claim in any permissible manner, and Executive agrees to prosecute such contest to a determination before any administrative tribunal, in a court of initial jurisdiction and in one or more appellate courts, as the Company shall determine; provided, however, that if the Company directs Executive to pay such claim and sue for a refund, the Company shall advance the amount of such payment to Executive, on an interest-free basis, and shall indemnify and hold Executive harmless, on an after-tax basis, from any Excise Tax or income tax (including interest or penalties with respect thereto) imposed with respect to such advance or with respect to any imputed income with respect to such advance; and further provided that any extension of the statute of limitations

relating to payment of taxes for the taxable year of Executive with respect to which such contested amount is claimed to be due is limited solely to such contested amount. Furthermore, the Company’s control of the contest shall be limited to issues with respect to which a Gross-Up Payment would be payable hereunder and Executive shall be entitled to settle or contest, as the case may be, any other issue raised by the Internal Revenue Service or any other taxing authority.

(iii)                                                     Notwithstanding any other provision of this Agreement, the Company may, in its sole discretion, withhold and pay over to the Internal Revenue Service or any other applicable taxing authority, for the benefit of the Executive, all or any portion of any Gross-Up Payment, and the Executive hereby consents to such withholding.

(iv)                                                    If Executive becomes entitled to receive any refund with respect to any Gross-Up Payment or with respect to an amount advanced by the Company pursuant to Section 7(i)(ii), Executive shall promptly pay to the Company the amount of such refund (together with any interest paid or credited thereon after taxes applicable thereto).  If, after the receipt by Executive of an amount advanced by the Company pursuant to Section 7(i)(ii), a determination is made that Executive shall not be entitled to any refund with respect to such claim and, if Executive has provided prompt written notice of such denial to the Company and the Company does not thereafter notify Executive in writing of its intent to contest such denial of refund prior to the expiration of the time period under applicable law in which such contest may be made by or on behalf of Executive, then such advance shall be forgiven and shall not be required to be repaid and the amount of such advance shall offset, to the extent thereof, the amount of the Gross-Up Payment required to be paid.

(v)                                                       Subject to the earlier time limits set forth above, all payments and reimbursements to which the Executive is entitled under this Section 7(i) shall be made not later than the end of the taxable year of the Executive next following the taxable year of the Executive in which the Executive (or the Company, on the Executive’s behalf) remits the related taxes (or, in the event of reimbursement with respect to an audit or litigation that does not result in the payment of taxes, not later than the end of the taxable year of the Executive next following the taxable year of the Executive in which there is a final resolution of such audit or litigation (whether by reason of completion of the audit, entry of a final and non-appealable judgment, final settlement, or otherwise)).

5.                                                              Medical Benefits

The following paragraph shall be added as Section 7(j) to the Employment Agreement:

(j)                                                           Upon any termination of the Executive’s employment during the Employment Term other than by the Company for Cause, the Company shall pay for the continued medical benefits for the

Executive and his family and any associated costs under (and in accordance with the terms of) COBRA for fifteen calendar months after the termination date.  The Executive shall pay for the remaining COBRA entitlement period.

6.                                                              Non-compete

As a result of the NTL-Telewest merger and the acquisition of Virgin Mobile, we have agreed to expand the non-compete provisions to cover mobile telephone and content, and accordingly, Section 9(b) of the Employment Agreement is amended in its entirety to read as set forth on Exhibit A.

(iii)                                              The Executive has provided the UK Independent Adviser with all available information which the UK Independent Adviser requires or may require in order to advise whether the Executive has any such claims; and

(iv)                                             The Executive was advised by the UK Independent Adviser that there was in force, at the time when the Executive received the independent legal advice, a policy of insurance covering the risk of a claim by the Executive in respect of losses arising in consequence of that advice.
