CONFORMED COPY STRICTLY CONFIDENTIAL The Directors Telewest Communications Group Limited Unit 1 Genesis Business Park Albert Drive Woking Surrey GU21 5RW WITHOUT PREJUDICE 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 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 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.

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 (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. 3. The percentage of the Payment, when TSR is measured against the Relevant FT-SE 100 Companies, is as follows: (a) 50% of the Payment if the Company is in the 25th (or a higher) position; (b) 12 1/2% of the Payment if the Company is in the 50th position; (c) 0% of the Payment if the Company is in the 51st (or a lower) position; and pro rata for positions between those specified at (a) and (b) above. 4. The percentage of the Payment, when TSR is measured against the Relevant Comparator Companies, is as follows: (a) 50% of the Payment if the Company has an upper quartile position; 12 (b) 12 1/2% of the Payment if the Company is at the median position (or if there is no median position, the position immediately above the median position); (c) 0% of the Payment if the Company is below the median position; and pro rata for positions between those specified at (a) and (b) above. 5. The Remuneration Committee may make such adjustments to the method of calculating TSR or any other feature of this Appendix as it considers appropriate to ensure that the condition in this Appendix achieves its original purpose.
