                                                                   24 April 1998



Gentlemen

I am employed by the Company under a Service Agreement dated 7 August 1997 (the
AGREEMENT).

1. Subject to the conditions set out below, I hereby give notice to terminate
the Agreement on 15 June 1998.

2.1 The Company will pay me my salary and pension contributions for the month of
April 1998 in the normal course (my salary being paid at the rate of
(pound)350,000 per annum).

2.2 On or before 22 June 1998 the Company will pay me my salary for the period
to 15 June, any outstanding pension contributions due to 30 April and any
holiday pay outstanding as at 30 April and any other amounts owed to me as at
that date (including any expenses).

2.3 In addition, on 22 June 1998 or, if later, within 5 days of my complying
with paragraph 5 below, the Company will pay me, subject to deduction of income
tax and any other legally required deduction, the sum of (pound)494,375 (made up
as set out in Schedule 1), in lieu of notice and in full settlement of all my
rights, and any outstanding claims, under the Agreement, but without prejudice
to my rights under this Agreement.

3. The Company will continue to allow me to use my present company car and
retain my fuel card on the terms specified in clause 8 of the Agreement until 30
April 1999. I will then return that car to the Company's head office.

4. Notwithstanding that I shall not be an employee of any Telewest Group Company
the Company will also continue to provide private medical, permanent health and

<PAGE>
life insurance on the terms specified in clause 7 of the Agreement until 30
April 1999, provided that no adverse change shall be made to the level of any
such cover unless it is equivalent to any such change introduced for executive
directors generally. The Company shall similarly continue the Directors and
Officers Insurance Cover presently available until 30 April 2004 and shall
indemnify me against all liabilities, costs and expenses in connection with the
claims brought against, inter alia, the Company and me by Mr Alan Robinson.

5. I undertake to sign a letter of resignation as a director in the form of
Schedule 2 and to return to the Company all Telewest Group property, including
(other than my company car and fuel card), any company-sponsored credit/charge
cards, computer equipment, fax machine, board papers, documents, correspondence
and relevant copies thereof within 5 days of acceptance of this letter by the
Company.

6. The Company will procure that I will be permitted to exercise (subject to the
rules of each relevant scheme and to any applicable performance criteria) my
share options listed in Schedule 3 at any time between the first and last
exercise dates noted against each option. I accept that the option granted to me
under the Telewest 1995 Sharesave Scheme has lapsed (without prejudice to my
right to continue making contributions and to a refund of contributions).

7. It is agreed that the 475,183 shares awarded to me under the Telewest 1995
Restricted Share Scheme have vested and that the award may be exercised by me,
subject to and in accordance with the Scheme rules, as varied by the Agreement.

8. I acknowledge that all my rights in respect of an award under the Telewest
Equity Participation Plan have lapsed. It is agreed that I will receive the sum
of (pound)7,205 as compensation for the matching award of 7,790 shares (at
92.5p) which might have been made to me under the Plan. This payment will be
made at the same time and on the same terms (in particular as to any legally
required deduction of tax), as the payment due under paragraph 2 above.

9. It is agreed that I should have received two awards of shares under the
Telewest Long Term Incentive Plan as set out in Schedule 3. In order to
compensate me on terms which are as close as possible to those I would have
enjoyed had the awards been made, the provisions of Schedule 4 shall apply.

10. I accept that all the terms of the Agreement expressed to be operative after
termination (in particular, clauses 12 and 14) will remain in full force and
effect. The Company will consider favourably any request I might make for waiver
of any of the restrictions in clause 14 of the Agreement.

11. The Company will pay up to (pound)10,000 (plus VAT) direct to my legal
advisers by way of contribution to the legal fees (including disbursements)
which I have incurred in connection with the termination of my employment. The
Company will also arrange for me to receive outplacement counselling and
assistance up to a value of (pound)12,500 (plus VAT).

                                       2
<PAGE>
12. Save as required by law or to give effect to the terms of this letter or as
required by the listing rules of the London Stock Exchange or by a regulatory
authority neither I nor the Company (contracting for itself and on behalf of
each Telewest Group Company) will, without the written consent of the other:

o        disclose the terms of this agreement to anyone (other than to my
         professional advisers who require the information for necessary
         professional purposes);

o        directly or indirectly make any statement about matters concerning my
         directorship of the Company and all my other Telewest Group
         directorships or my employment with the Company (other than in the form
         of the attached public announcements); or

o        make any derogatory or disparaging comment about me, the Company any
         Telewest Group company, any corporate shareholder of Telewest
         Communications plc as at the date of this Agreement, or any of its or
         their respective directors or employees.

Providing that the Company may respond to proper enquiries by, or on behalf of,
shareholders, in a manner consistent with the attached public announcements.

13. In this letter Telewest Group shall mean any of:

o        Telewest Communications plc; and

o        any subsidiary of Telewest Communications plc from time to time.

Yours sincerely





STEPHEN DAVIDSON



I agree to the terms set out above.

obliged to transfer the Shares, unless either it has received on or prior to the

Tax Liability, or the Executive has entered into arrangements reasonably
acceptable to the Company to secure that such a payment is made.

9. In the event of any dispute or disagreement as to the interpretation of this
Schedule, or as to any question or right arising from or related to this
Schedule, the decision of the Remuneration Committee shall be final and binding
provided that it is accepted that any entitlement pursuant to this Schedule
shall be generally no less favourable (other than in relation to the proportion
of Relevant Shares applicable) than that of the majority of the Participants in
the Plan.

10. Any alterations made pursuant to Rule 7 of the Plan shall also be made to
the terms of this Schedule, where relevant.

                            THE SCHEDULE TO THE PLAN

PART A

1.       For the purposes of this Appendix:

(a)      TSR means total shareholder return, calculated by Datastream after:

             (i)  reinvesting dividends (plus associated tax credits) on a
                  company's shares on the day on which the shares went
                  ex-dividend on the London Stock Exchange;

            (ii)  making such adjustments to take account of any increase or
                  variation of the share capital of a company as the
                  Remuneration Committee considers relevant; and

           (iii)  averaging the index of closing share prices and reinvested
                  dividends for the period of three months preceding the
                  Performance Period and averaging the index of closing share
                  prices and reinvested dividends for the final three months of
                  the Performance Period.

(b)      THE FT-SE 100 INDEX means the Financial Times - Stock Exchange index of
         the market values of 100 leading UK equities;

(c)      THE COMPARATOR COMPANIES means the group of companies set out in Part B
         of this Appendix (or such other such group of companies as the Board
         may decide from time to time before a Payment is made, taking into
         account any factors considered by the Board to be relevant);

(d)      THE RELEVANT FT-SE 100 COMPANIES means the companies which were the
         constituent companies for the purposes of the FT-SE 100 Index at the
         commencement of the Performance Period in question and, if it was not
         such a company, the Company;

(e)      THE RELEVANT COMPARATOR COMPANIES means the Company and the Comparator
         Companies which were listed on the London Stock Exchange at the
         commencement of the Performance Period in question;

(f)      any reference to the Company's position is a reference to what would be
         its position in a table of the Relevant FT-SE 100 Companies or a table
         of the Relevant Comparator Companies arranged in descending order
         according to the TSR of each of them for the Performance Period;

(g)      in the event that one of the Relevant FT-SE 100 Companies or one of the
         Relevant Comparator Companies is taken over, the TSR of that company
         shall be calculated up to the date of change of control (within the
         meaning of section 840 of the Income and Corporation Taxes Act 1988) of
         that company on the basis that:


                                       11
<PAGE>
             (i)  if the takeover is on terms that an offer wholly or partly in
                  cash is made to shareholders, that cash is assumed to have
                  been reinvested in the FT-SE 100 Index for the balance of the
                  Performance Period;

            (ii)  if the takeover is on terms that it is compulsory for part or
                  all of the offer to be satisfied in the form of shares, those
                  shares are assumed to be held until the end of the Performance
                  Period.

(h)      in the event of a demerger of one of the Relevant FT-SE 100 Companies
         or one of the Relevant Comparator Companies into two or more companies
         quoted on a recognised stock exchange (within the meaning of that term
         as set out in section 841 of the Income and Corporation Taxes Act
         1988), the TSR of the relevant company will be calculated by
         aggregating the total shareholder return of the demerged company or
         companies and the company from which it or they demerged for the part
         of the Performance Period following the demerger become effective.

2. If one of the events specified in paragraph 4 of Schedule 4 of this Agreement
occurs, for the purposes of the calculation of TSR the middle-market quotation
of the Relevant FT-SE 100 Companies or the Relevant Comparator Companies on such
date shall be taken as the final share price of such companies (and the final
share price shall not be averaged) and the final share price of the Company
shall be taken as the most valuable option offered to shareholders in the
Company as at the date of such event.
