Confirmation of Amendment of Employment Agreement dated as of 4th March 2003
(the "Agreement")

Dear Rick:

As we have discussed, now that NTL Incorporated (the "Company") has emerged from
its Chapter 11 reorganisation and has successfully completed its $1.4 billion
equity offering and multibillion bond and credit agreement financings, it is
entering into a new phase of its existence. The Company therefore has new
initiatives and projects which require the reshaping of the management team. In
particular, as we previously agreed, on 30th June 2004 we assigned you as
Project Director of the Broadcast sale process and you have been leading the
team in this role as of that date.

The employment term under your Agreement expires on 30th June 2005 (the
"Termination Date") and we have discussed together your own plans and the
Company's plans on a going forward basis.

This letter confirms our prior agreement that your Employment Term under the
Agreement will not be renewed and your employment with the Company will
terminate on the Termination Date. (Terms not otherwise defined in this Letter
are used as defined in the Agreement.)

1.Amendment of Agreement. Subject to the agreements set forth in this Letter
which amend and supplement the Agreement, the Agreement shall remain in full
force and effect until the Termination Date unless otherwise terminated in
accordance with its terms.

2.Non-Renewal. It has been agreed between us that the Employment Term shall end
on 30th June 2005 and, for the avoidance of doubt, this Letter constitutes
formal written notice of non-renewal of the Employment Term. Accordingly, as
soon as practicable following the Termination Date and your execution and
delivery of the general release as provided for by the terms of Section 7c of
the Agreement, the Company shall pay to you a lump-sum severance payment of cash
equal to the product of the Base Salary times 2 (as provided by Section 7c).
Notwithstanding the foregoing, should there be a Termination Without Cause or a
Constructive Termination Without Cause in advance of 30th June 2005, the Company
shall, as soon as practicable following such termination and the Executive's
execution and delivery to the Company of the general release of claims set forth
in Section 7(f), pay to you a lump-sum severance payment of cash equal to the
product of the Base Salary times 3 (as provided by Section 7b).

3.Duties; title. From and after 30th June 2004 you have been acting as the
Company's Project Director for the ntl: Broadcast transaction, reporting to
Scott Schubert (Executive Vice President—Corporate Development) and Bryan Hall
(Secretary and General Counsel). You have been assigned full-time to the
separation and strategic execution of ntl: Broadcast's operations and such other
similar duties as may be requested from time to time.

--------------------------------------------------------------------------------

You may serve on the board of directors for no more than one for-profit company,
subject however to prior notification to be provided to the President of the
Company and provided that such endeavours do not interfere with the conduct of
your duties and that the identity of such company is subject to the reasonable
consent of the Company. Any and all travel expenses and other expenses
associated with such position shall be borne by such other company or you.

4.Base Salary: Benefits. Your Base Salary will remain unchanged by the signing
of this Letter, but you shall remain eligible for any general salary increases
through the Termination Date. You will continue to be eligible for all bonuses
as per the Agreement and all benefits including ex-patriate benefits (on a pro
rata basis as may be appropriate). In addition, you will be a participant in the
Company's Long Term Incentive Plan ("LTIP") and notwithstanding that the
Termination Date is prior to the date the LTIP payments will be made, you will
remain eligible to receive those payments pro-rated to the Termination Date;
provided that (i) you have not been Terminated for Cause; (ii) you have not
resigned from your position and (iii) you are not in breach of the Agreement.
(Actual amounts paid, if any, will of course be subject to the terms of the
LTIP). Vacation days for the calendar year will be determined on a pro rata
basis. You will be permitted to carry over all unused days from your 2004
holiday entitlement, as approved by Simon Duffy (Chief Executive Officer) on
14th November 2004.

5.Options. Your options which are subject to vesting on 11th April 2006 will
vest on the Termination Date (even if the Company has effected a Termination
Without Cause); provided that (i) you have not been Terminated for Cause;
(ii) you have not resigned from your position and (iii) you are not in breach of
the Agreement. The terms of the options will continue in full force and effect.

6.Exchange Rates. As per the terms of the Agreement, you will be entitled to
designate at one time during each calendar year (commencing on or after 1st
January 2005) a percentage of cash compensation not yet paid to be paid in US
Dollars, with the exchange rate set on the date such designation is made as
provided by Section 3a of the Agreement. The foregoing designation right applies
with respect to years occurring after termination of the Employment Term in
which any cash payments will be made.

7.Miscellaneous. This Letter shall be governed by and construed in accordance
with the internal laws of the State of Delaware, without reference to the
principles of conflicts of laws. This Letter shall be subject to all other terms
of the Agreement (such as address for notices, jurisdiction, etc). The parties
agree that the Agreement shall remain in full force and effect except as
modified by the terms hereof.

Letter in the space provided below.
