    Committee (as applicable to you), the AGM, one annual Board strategy session
    lasting two days and at least one site visit per year. In addition, you will

Dear Mr Myners,

This letter
  sets out the terms of your appointment as a non-executive director of mmO2 plc

  of this letter shallreplace
  the terms of any existing letters relating to such appointment.

The term of your appointment is initially for a period which expires 3 years after the date the demerger becomes effective, expected to be on 19 November 2001. At the end of that period, your appointment may be continued if you and the mmO2 plc Board agree. From that date, either you or the Board can give the other at least twelve months written notice to terminate the appointment at any time.

You will need periodically to seek re-election at the Annual General Meeting in accordance with the Companys Articles of Association.

Conditional upon and from the date of the demerger, you will receive fees for your services as a non-executive director of £30,000 a year, which includes membership of one Board Committee. A further £3,000 a year will be paid for membership of each additional Committee.

You will be expected to attend all meetings of the Board (including awaydays, which may last for more than one day), Committees of which you are a member and Annual and Extraordinary General Meetings.

Whilst it is
  difficult to be precise about the amount of time you should expect to spend
  on this work, you should plan on there being around ten Board meetings a year.
  You should allow for some additional meetings in the immediate period as and
  after

    and consideration the proposed revised terms of your appointment. In the event
    that these are acceptable to you please sign the copy of this letter and return
    it to me. It is agreed that this is a contract for services and is not a contract
    of employment.

1. APPOINTMENT

Your appointment was
    for an initial term of three years, commencing on 19th November 2001, unless
    otherwise terminated earlier by and at the discretion of either party upon
    one months written notice. Continuation of your contract of appointment is
    contingent on satisfactory performance and re-election at forthcoming AGMs.
    Non-executive Directors are typically expected to serve two three-year terms,
    although the Board may invite you to serve for an additional period. In addition,
    you have agreed to serve on the Nomination and Remuneration committees with
    effect from 1st April 2003. A copy of the Terms of Reference of the Committees
    have already been provided to you.

    (as applicable to you), the AGM, one annual Board strategy session lasting
    two days and at least one site visit per year. In addition, you will be expected
    to devote appropriate preparation time ahead of each meeting.

Back to Contents  Mr Ian Meakins BY HAND 23rd May 2003  Revised Terms of Appointment
    as a Non-Executive Director You were appointed to
    the Board on 20th December 2001. Following on our recent discussions of the
    latest developments in best practice, I am writing to set out for your review
    and consideration the proposed revised terms of your appointment. In the event
    that these are acceptable to you please sign the copy of this letter and return
    it to me. It is agreed that this is a contract for services and is not a contract
    of employment. 1. APPOINTMENT Your appointment was
    for an initial term of three years, commencing on 20th December 2001, unless
    otherwise terminated earlier by and at the discretion of either party upon
    one months written notice. Continuation of your contract of appointment
    is contingent on satisfactory performance and re-election at forthcoming AGMs.
    Non-executive Directors are typically expected to serve two three-year terms,
    although the Board may invite you to serve for an additional period. In addition,
    you have agreed to serve on the Audit and Remuneration committees with effect
    from 1st April 2003. A copy of the Terms of Reference of the Committees have
    already been provided to you. 2. TIME COMMITMENT We anticipate that your
    appointment will require a time commitment of around two days per month. This
    will include attendance at around ten board meetings, around four meetings
    of the Audit and Remuneration Committees and around two meetings of the Nomination
    Committee (as applicable to you), the AGM, one annual Board strategy session
    lasting two days and at least one site visit per year. In addition, you will
    be expected to devote appropriate preparation time ahead of each meeting. By accepting this appointment,
    you have confirmed that you are able to allocate sufficient time to meet the
    expectations of your role. If, during your appointment, you wish to accept
    any public appointment or further directorship, you will be required to obtain
    prior approval of the Companys Nomination Committee. Such approval will
    not be unreasonably withheld provided (a) the likely time commitment for the
    other role will not affect your ability to give priority to your duties under
    this appointment, and (b) the other role does not give rise to competitive,
    conflict or reputational issues for the Company. ChairmanmmO2 plc

    have the same general legal responsibilities to the Company as any other Director.
    The Board as a whole is collectively responsible for promoting the success
    of the Company by directing and supervising the Companys affairs. The
    Board: •
      provides entrepreneurial
        leadership of the Company within a framework of prudent and effective
        controls which enable risk to be assessed and managed;•
      sets the Companys
        strategic aims, ensures that the necessary financial and human resources
        are in place for the Company to meet its objectives, and reviews management
        performance; and•
      sets the Companys
        values and standards and ensures that its obligations to its shareholders
        and others are understood and met. In addition to these requirements
    of all Directors, the role of the non-executive has the following key elements: •
      Strategy: Non-executive
        Directors should constructively challenge and contribute to the development
        of strategy;•
      Performance:
        Non-executive Directors should scrutinise the performance of management
        in meeting agreed goals and objectives and monitor the reporting of performance;•
      Risk: Non-executive
        Directors should satisfy themselves that financial information is accurate
        and that financial controls and systems of risk management are robust
        and defensible; and•
      People: Non-executive
        Directors are responsible for determining appropriate levels of remuneration
        of executive Directors and have a prime role in appointing and where necessary
        removing senior management and in succession planning. As
        an effective non-executive Director, we would expect you to:•
      Uphold the highest
        ethical standards of integrity and probity;•
      Support executives
        in the leadership of the business whilst monitoring their conduct;•
      Question intelligently,
        debate constructively;•
      Challenge rigorously
        and decide dispassionately;•
      Listen sensitively
        to the views of others, inside and outside the board;•
      Gain the trust and
        respect of other Board members and•
      Promote the highest
        standards of corporate governance 2

      reputation; or

  the Executive is unable (whether due to illness or otherwise) properly and effectively
  to perform his duties under this Agreement for a period or periods totalling
  (in aggregate) 9 months in any consecutive period of 12 months, provided that
  the Company will not terminate the Employment if to do so would have the effect
  of causing the Executive to forfeit any entitlement to benefit under the Companys
  permanent health insurance arrangements. In these circumstances, the Company
  may take such steps as it considers appropriate in relation to the Employment
  including, without limitation, discontinuing salary and all other rights and
  benefits provided under this Agreement (apart from permanent health benefits).

      of the notice period);

  Lieu of Notice shall be subject to such deductions as the Company may be required

  Executives directorship of the Company or any Group Company. The Payment in
  Lieu of Notice may, at the Companys discretion, be paid as a lump sum (within
  10 working days of the last day of the Employment) or in equal monthly instalments
  from the Termination Date until the date which is twelve months after the Termination
  Date (or if notice had already been served before the Termination Date, the
  remainder of the notice period) or if sooner, the date on which the Executive
  commences alternative employment. Any entitlement which the Executive has or
  may have under any share related incentive scheme shall be determined in accordance
  with the rules of such scheme. For the avoidance of doubt, (1) the Company is
  only to be taken as exercising the right given by this clause, and accordingly
  to be liable for the Payment in Lieu of Notice, if it gives the written notice
  referred to above explicitly invoking this clause; and (2) any delay or error
  in the Payment in Lieu of Notice shall not affect the lawfulness of a termination
  under this clause.

17.6     Upon termination
  of the Employment the Executive will at the Companys request promptly resign
  in writing as a director of the Company and any Group Company and will promptly
  return to the Company any property of the Company and any Group Company. The
  Secretary of the Company is irrevocably authorised to sign letters of resignation
  on the Executives behalf if he fails to do so.

LIQUIDATED DAMAGES

18.1     If the Employment
  is terminated otherwise than in accordance with the terms of this Agreement
  (including, without limitation, if the Executive is constructively dismissed)
  the Company will pay to the Executive a liquidated sum calculated by reference
  to the Payment in Lieu of Notice set out in clause 17.4 (or clause 19.4 as appropriate)
  and paid subject to the terms of clause 17.5. The liquidated sum will be subject
  to such deductions as the Company may be required to make and will be in full
  and final settlement of any claims which the Executive has or may have against
  the company or any other Group Company arisingout
  of or in connection with the Executives employment or its termination.
  In consideration for this payment the Executive agrees to remain bound by the
  post-termination restrictions in the Schedule to this Agreement.

  concert with him to control the composition of the board of directors of the
  Company or otherwise to secure whether by means of the holding of shares or
  the possession of voting power in relation to the Company or any other body

  or any other document or agreement regulating the Company or any other body
  corporate that the affairs of the Company are conducted with the wishes of that

19.3     For the period
  of 12 months following a Change of Control clause 17.4 shall be replaced by

  and all other rights and benefits provided under this Agreement (apart from
  permanent health insurance for the Executive).

      of the notice period); and

      him with retirement benefits in respect of the unexpired portion of the
      notice period (or part thereof);

  to make and shall be in full and final settlement of allclaimsthe Executive may have against the Company or any Group Company (whether known
  or unknown) arising out of or in connection with the termination of the Employment
  and the Executive’s directorship of the Company or any Group Company. The Payment
  in Lieu of Notice may, at the Company’s discretion, be paid as a lump sum (within
  10 working days of the last day of the Employment) or in equal monthly instalments
  from the Termination Date until the date which is twelve months after the Termination
  Date (or if notice had already been served before the

Termination Date, the remainder of the notice period)
  or if sooner, the date on which the Executive commences alternative employment.
  Any entitlement which the Executive has or may have under any share related
  incentive scheme shall be determined in accordance with the rules of such scheme.
  For the avoidance of doubt, (1) the Company is only to be taken as exercising
  the right given by this clause, and accordingly to be liable for the Payment
  in Lieu of Notice, if it gives the written notice referred to above explicitly
  invoking this clause; (2) any delay or error in the Payment in Lieu of Notice
  shall not affect the lawfulness of a termination under this clause; and (3)
  any Payment in Lieu of Notice shall be without prejudice to the Executive’s
  rights in respect of any accrued but unpaid bonus for the bonus year prior to
  the bonus year in which the Termination Date falls.

  to such deductions as the Company may be required to make and will be in full
  and final settlement of any claims which the Executive has or may have against
  the company or any other Group Company arising out of or in connection with
  the Executive’s employment or its termination. In consideration for this payment
  the Executive agrees to remain bound by the post-termination restrictions in
  the Schedule to this Agreement.

  of clause 19.1 constructive dismissal shall include (but not be limited to):

CHANGE OF CONTROL

20.1    For the purposes
  of this clause 20.1:

Controlmeans the power of any person
  whether alone or together with any person acting in concert with him to control
  the composition of the board of directors of the Company or otherwise to secure
  whether by means of the holding of shares or the possession of voting power
  in relation to the Company or any other body corporate or by virtue of any powers
  conferred by the articles of association or any other document or agreement
  regulating the Company or any other body corporate that the affairs of the Company
  are conducted with the wishes of that person; and

Changeof Controlmeans:
  (i) the disposal of all or substantially all of the Company; or (ii) the acquisition
  by any person whether alone or together with any person acting in concert with
  him of Control of the Company; but shall not mean an acquisition of Control
  of the Company by another company the shares of which, immediately following
  such an acquisition, are all held by the holders of the shares of the Company
  immediately prior to such an acquisition in materially the same proportion as
  they held shares in the Company immediately prior to such an acquisition.

20.2    If a Change of
  Control occurs the period of notice which the Company or the Executive is required
  to give to the other to terminate the employment in accordance with clause 18.1
  will be unaffected and will remain as 12 months and 6 months respectively.

20.3    For the period
  of 12 months following a Change of Control clause 18.4 shall be replaced by
  clause 20.4 unless clause 18.4 has already been operated prior to the Change
  of Control.

20.4    The Company may,
  in its sole discretion, also terminate the Executive’s employment by giving
  written notice to the Executive that it is exercising its discretion under this
  clause 20.4 to terminate the Employment with effect from such date as is specified
  in the notice (the Termination Date).In such a case the Company
  shall be obliged within 10 working days after the Termination Date to pay to
  the Executive a sum (the Payment in Lieu of Notice)equal to:

|(a) | the basic annual salary which the
      Executive would have been entitled to receive under the terms of this Agreement
      during the notice period referred to in clause 18.1 if notice had been given
      on the Termination Date (or, if notice has already been given, during the
      remainder of the notice period);

|(b) | the cost of contributions made
      by the Company towards the cost of retirement provision for the Executive
      during that period. Alternatively, the Company may, if it so chooses, make
      the contributions directly to the Executive’s pension arrangements to provide
      the Executive with retirement benefits in respect of the unexpired portion
      of the Executive’s notice period (or part thereof);
|    |                                                                                                                                                                                                                                                                                                                                                                                                                               
|(c) | the cost of the other contractual
      benefits which the Executive would have been entitled to receive during
      that period. Alternatively, the Company may, if it so

      contractual benefits during that period. At the Executive’s request the
      Company will continue to pay insurance premiums for medical and dental treatment
      in the United States during that period, regardless of its treatment of
      other contractual benefits under this sub-clause; and

|B | is the aggregate value, on the
      date of the Change of Control, of those share awards and share options which
      were exercised or exercisable by the Executive between the date of the Change
      of Control and the Termination Date (as reduced by the operation of any
      applicable performance condition).

For the purposes of this clause 20.5, the Executive
  may be required to waive any share awards or share options which, in accordance
  with their terms, may vest or become exercisable after the Termination Date.

20.6    The Payment in Lieu
  of Notice shall be subject to such deductions as the Company may be required
  to make and shall be in full and final settlement of all claims the Executive
  may have against the Company or any Group Company (whether known or unknown)
  arising out of or in connection with the termination of the Employment and the
  Executive’s directorship of the Company or any Group Company.

20.7    For the avoidance
  of doubt, (1) the Company is only to be taken as exercising the right given
  by this clause, and accordingly to be liable for the Payment in Lieu of Notice,
  if it gives the written notice referred to above explicitly invoking this clause;
  and (2) any delay or error in the Payment in Lieu of Notice shall not affect
  the lawfulness of a termination under this clause; and (3) any Payment in Lieu
  of Notice shall be without prejudice to the Executive’s rights in respect of
  any accrued but unpaid bonus for the bonus year prior to the bonus year in which
  the Termination Date falls.

21.    For
  the purposes of paragraph 20 above, and not in any other circumstances, the
  payments set out (being payments made in accordance with this Agreement) will

22.    It
  shall be part of the Executive’s normal duties (whether or not during normal
  working hours and whether or not at the Executive’s normal place of work) at
  all times to consider in what manner and by what new methods or devices the
  products, services, processes, equipment or systems of the Company with which
  he is concerned or for which he is responsible might be improved and to originate
  designs (whether registrable or not) or patentable work or other work in which
  copyright may subsist. Accordingly:

      Executive shall forthwith disclose full details of the same in confidence
      to the Company and shall regard himself in relation thereto as a trustee

|6.    | For the avoidance of
      doubt it is expressly agreed that each of the sub-clauses (i)-(iii) in Clause
      2 is intended to contain separate and severable restraints and if any one
      or more of such sub-clauses are for any reason unenforceable in whole or
      in part, then the other sub-clauses shall nonetheless be and remain effective.

      the Executive will provide a copy of this Schedule to the offeror as soon
      as is reasonably practicable after receiving the offer and if he accepts
      the offer he will inform the Company immediately.

      salary for the period from the Effective Date to 31 March 2003 is €485,300.00.
      If the Appointment (as defined in Art. 3.2) takes effect on 1
      April 2003, the Executive’s gross basic annual salary with effect from that
      date shall be €412,500.00 (such reduction being made by reason of the salary

      3.2). This basic annual salary (the Basic Salary)shall be
      paid less such deductions as the Company is required to make under law and

      be undertaken after notice has been given by either party to terminate the
      Employment. The Company is under no obligation to increase the Executive’s
      salary following a salary review, but will not decrease it. |  | 3.1

|5.                               | It is the Company’s intention
      to make annual grants of share awards and it is currently expected that
      these awards will be granted under the Share Option element of the mmO2
      Executive Share Portfolio. The level of awards will be decided by mmO2’s
      Remuneration Committee but for the 2003 fiscal year mmO2’s
      Remuneration Committee has approved an award of options over mmO2
      shares with an aggregate exercise price equivalent to 1 x Basic Salary subject
      to satisfaction of performance targets determined by mmO2’s Remuneration
      Committee and in accordance with the rules of the scheme. “Basic Salary”
      shall be determined in the same manner as set out in Art. 4.2. |                                 | 5.  | Die Gesellschaft beabsichtigt
      jährlich Beteiligungsprämien zu gewähren und es wird gegenwärtig
      erwartet, dass diese gemäß dem Aktienoptions-Bestandteil des
      mmO2 Executive Share Portfolio gewährt werden. Die Höhe
      der Zuteilungen wird von dem Remuneration Committee von mmO2
      entschieden, jedoch ist für das Geschäftsjahr 2003 eine Zuteilung
      von Optionen über mmO2-Aktien genehmigt worden, welche einen
      Gesamtausübungspreis haben, welcher 1 x dem Grundgehalt entspricht,
      abhängig von der Erfüllung von Leistungszielen, welche von dem
      Remuneration Committee von mmO2 in Übereinstimmung mit den
      Regelungen des Beteiligungsprogramms festgelegt werden. “Grundgehalt”
      wird dabei in gleicher Weise berechnet, wie in Art. 4.2 beschrieben.

Dear Rudi

  plc (the Company)

On behalf of mmO2 plc, I write to confirm various
  matters following your appointment as a Director of the Company (the Appointment).

Appointment

1.     The Appointment
  will be on the terms set out in this letter. Your appointment as CEO of O2 (Germany)
  Management GmbH will continue in place, and is now governed by a service agreement
  dated 31 March 2003 (the German Contract).The German Contract
  became effective on 1 November 2002 , and will run in tandem with the Appointment.
  For the avoidance of doubt, the Appointment may be terminated without such event
  constituting a breach of the German Contract, or an event entitling you to terminate
  the German Contract.

2.     You are aware that
  the Appointment is subject to re-election when appropriate by the Company in
  a General Meeting. If the Appointment is not renewed on such re-election, you
  undertake to resign as a Director of the Company forthwith. In addition, the
  Appointment may be terminated at any time in accordance with the provisions
  of the Articles of Association of the Company, or by giving you 12 months’
  written notice of termination.

Duties

3.     During the Appointment,
  you will be required to attend (wherever practicable) the annual general meeting
  of the Company, regular and emergency Board meetings, Board “awaydays”,
  and any extraordinary general meeting of the Company. The dates and details
  of these meetings (which are generally held in the UK) will be notified to you
  as far in advance as is practicable. These duties are likely to take up around
  30 days per year, and you are aware that the German Contract releases you to
  perform these duties. It is anticipated that the annual general meeting of the
  Company shall be held in or about July each year.

This clause shall not restrict any other right the Company may have (whether at common law or otherwise) to terminate the Employment summarily. Any delay by the Company in exercising its rights under this clause shall not constitute a waiver of those rights.

17.3     The
  Company may also terminate the Employment by giving 12 months notice to the
  Executive if the Executive is unable (whether due to illness or otherwise) properly
  and effectively to perform his duties under this Agreement for a period or periods
  totalling (in aggregate) 9 months in any consecutive period of 12 months, provided
  that the Company will not terminate the Employment if to do so would have the
  effect of causing the Executive to forfeit any entitlement to benefit under
  the Company’s permanent health insurance arrangements. In these circumstances,
  the Company may take such steps as it considers appropriate in relation to the
  Employment including, without limitation, discontinuing salary and all other
  rights and benefits provided under this Agreement (apart from permanent health
  benefits).

17.4     The
  Company may, in its sole discretion, also terminate the Executive’s employment
  by giving written notice to him that it is exercising its discretion under this
  clause 17.4 to terminate the Employment with effect from such date as is specified
  in the notice (theTermination
  Date).In
  such a case the Company shall be obliged to pay to the Executive a sum (thePayment
  in Lieu ofNotice)equal
  to:

|(a) | the
      basic annual salary which the Executive would have been entitled to receive
      under this Agreement during the notice period referred to in clause 17.1
      if notice had been given on the Termination Date (or, if notice has already
      been given, during the remainder of the notice period); and

|(b) | the
      cost of contributions which would have been made by the Company towards
      the cost of retirement provision for the Executive during that period. Alternatively,
      the Company may, if it so chooses, make the contributions directly to the
      Executive’s pension arrangements to provide him with retirement benefits
      in respect of the unexpired portion of the notice period (or
      part thereof);

|(c) | the
      value of any bonus payment which would have been made under clause 5. The
      payment made in respect of bonus under this clause 17.4 shall be not less
      than the amount which is equal to the bonus payment (if any) received by
      the Executive in respect of the bonus year preceding the Termination Date.
      Where the Payment in Lieu of Notice is in respect of a period which is less
      than one year, any payment in respect of bonus shall be adjusted downwards
      as applicable; and

|(d) | the
      cost of the other contractual benefits which the Executive would have been
      entitled to receive during that period. Alternatively the Company may, if
      it so chooses, continue to provide those contractual benefits during that
      period.                                                                                                                                                                                                                                                             

17.5     The
  Payment in Lieu of Notice shall be subject to such deductions as the Company
  may be required to make and shall be in full and final settlement of all claims
  the Executive may have against the Company or any Group Company (whether known
  or unknown) arising out of or in connection with the termination of

the Employment and the Executive’s directorship of the Company or any Group Company. The Payment in Lieu of Notice may, at the Company’s discretion, be paid as a lump sum (within 10 working days of the last day of the Employment) or in equal monthly instalments from the Termination Date until the date which is twelve months after the Termination Date (or if notice had already been served before the Termination Date, the remainder of the notice period) or if sooner, the date on which the Executive commences an alternative employment at a basic annual salary in excess of 50% of the Executive’s basic annual salary under this Agreement at the Termination Date (unless the Company elects, at its discretion, to disregard such an employment for the purposes of this clause). Any entitlement which the Executive has or may have under any share related incentive scheme shall be determined in accordance with the rules of such scheme. For the avoidance of doubt, (1) the Company is only to be taken as exercising the right given by this clause, and accordingly to be liable for the Payment in Lieu of Notice, if it gives the written notice referred to above explicitly invoking this clause; and (2) any delay or error in the Payment in Lieu of Notice shall not affect the lawfulness of a termination under this clause.

17.6     Upon
  termination of the Employment (whether in breach of contract or not) the Executive
  will:

|(a) | at
      the Company’s request promptly resign in writing as a director of the Company
      and any Group Company. The Secretary of the Company is irrevocably authorised
      to sign letters of resignation on the Executive’s behalf if he fails to
      do so;

|(c) | immediately
      pay to the Company or any Group Company all outstanding loans or other amounts
      due or owed to the Company or any Group Company. The Executive confirms
      that, should he fail to do so, the Company is to be treated as authorised
      to deduct from any amounts due or owed to the Executive by the Company (or
      any other Group Company) a sum equal to such amounts.

17.7     The
  Executive will not at any time after termination of the Employment represent
  himself as being in any way concerned with or interested in the business of,
  or employed by, the Company or any other Group Company.

LIQUIDATED
  DAMAGES

18.1     If
  the Employment is terminated otherwise than in accordance with the terns of
  this Agreement (including, without limitation, if the Executive is constructively
  dismissed) the Company will pay to the Executive a liquidated sum calculated
  by reference to the Payment in Lieu of Notice set out in clause 17.4 (or the
  Special Payment in Lieu of Notice under clause 19.4 as appropriate) and paid
  subject to the terms of clause 17.5. In consideration for this payment the Executive
  agrees to remain bound by the post-termination restrictions in the Schedule
  to this Agreement.

For the purposes of this clause 19.5, the Executive
  may be required to waive any share awards or share options which, in accordance
  with their terms, may vest or become exercisable after the Termination Date.

19.6     The Special Payment
  in Lieu of Notice shall be subject to such deductions as the Company may be
  required to make and shall be in full and final settlement of all claims the
  Executive may have against the Company or any Group Company (whether known or
  unknown) arising out of or in connection with the termination of the Employment
  and the Executive’s directorship of the Company or any Group Company. For the
  avoidance of doubt, (1) the Company is only to be taken as exercising the right
  given by this clause, and accordingly to be liable for the Special Payment in
  Lieu of Notice, if it gives the written notice referred to above explicitly
  invoking this clause; and (2) any delay or error in the Special Payment in Lieu
  of Notice shall not affect the lawfulness of a termination under this clause.

MITIGATION

20.     For the purposes
  of paragraph 19 above, and not in any other circumstances, the payments set
  out (being payments made in accordance with this Agreement) will not be subject
  to mitigation, and will be paid irrespective of whether the Executive obtains
  alternative employment within the applicable notice period.

INTELLECTUAL PROPERTY

21.     It shall be part
  of the Executive’s normal duties (whether or not during normal working hours
  and whether or not at the Executive’s normal place of work) at all times to
  consider in what manner and by what new methods or devices the products, services,
  processes, equipment or systems of the Company with which he is concerned or
  for which he is responsible might be improved and to originate designs (whether
  registrable or not) or patentable work or other work in which copyright may
  subsist. Accordingly:

      to those contained in clause 2(i)-(iii) inclusive (or such as may be appropriate
      in the circumstances).

      the restraints contained in this Schedule and each of them are necessary
      to protect the legitimate interests of the Company and the Group Companies,
      and that the same are no wider than reasonably necessary for that purpose,
      and are reasonable as between the parties to this Agreement.

|5.    | If any of the restrictions contained
      in this Schedule shall be adjudged to be void or ineffective or unenforceable
      for whatever reason but would be adjudged to be valid and effective if part
      of the wording were deleted or the periods reduced or the area reduced in
      scope, they shall apply with such modifications as may be necessary to make
      them valid and effective.

|6.    | For the avoidance of doubt it is
      expressly agreed that each of the sub-clauses (i)-(iii) in Clause 2 is intended
      to contain separate and severable restraints and if any one or more of such
      sub-clauses are for any reason unenforceable in whole or in part, then the
      other sub-clauses shall nonetheless be and remain effective.

  which shall be calculated so as to adequately compensate the Executive for loss
  of his company car or the Cash Alternative.

HOLIDAY

11.1    The Executive is entitled
  to paid English bank and public holidays and to 25 days paid holiday in each
  year (1 April to 31 March) or on a pro-rata basis as appropriate, rising to
  30 days on the date which is five years after the date of commencement of your
  employment with BT. Holiday may not be carried over to a subsequent holiday
  year.

11.2    Any outstanding
  leave must be taken during the Executive’s notice period and no payment will
  be made for any unused annual leave as at the termination of the Employment
  (unless the CEO has not allowed outstanding holiday to be taken during the Executive’s
  notice period). If the Executive has taken more working days’ paid holiday than
  his accrued entitlement, the Company is permitted to deduct the appropriate
  amount from the Executive’s final salary instalment (which deduction shall be
  made on the basis that each day of paid holiday is equivalent to 1/260 of basic
  annual salary).

17.1    Either the Company
  or the Executive may terminate the Executive’s Employment at any time by giving
  to the other 12 months’ written notice. This Agreement will terminate immediately
  without notice when the Executive reaches age 60.

17.2    Notwithstanding
  clause 17.1 the Company may terminate this contract without notice and without
  compensation if it has reason to believe that the Executive:

|(a) | is guilty of any dishonesty or disreputable
      conduct which is likely substantially to affect the Company’s reputation;
      or                   
|--- | -------------------------------------------------------------------------------------------------------------------------------------------------------

  under this clause shall notconstitute a waiver
  of those rights.

17.3    The Company may also
  terminate the Employment by giving 12 months’ notice to the Executive if the
  Executive is unable (whether due to illness or otherwise) properly and effectively
  to perform his duties under this Agreement for a period or periods totalling
  (in aggregate) 9 months in any consecutive period of 12 months, provided that
  the Company will not terminate the Employment if to do so would have the effect
  of causing the Executive to forfeit any entitlement to benefit under the Company’s
  permanent health insurance arrangements. In these circumstances, the Company
  may take such steps as it considers appropriate in relation to the Employment
  including, without limitation, discontinuing salary and all other rights and
  benefits provided under this Agreement (apart from permanent health benefits).

17.4     The Company may,
  in its sole discretion, also terminate the Executive’s employment by giving
  written notice to him that it is exercising its discretion under this clause
  17.4 to terminate the Employment with effect from such date as is specified
  in the notice (the Termination Date). In such a case the Company
  shall be obliged to pay to the Executive a sum (the Payment in Lieu of
  Notice) equal to:

|(a) | the basic annual salary which
      the Executive would have been entitled to receive under this Agreement during
      the notice period referred to in clause 17.1 if notice had been given on
      the Termination Date (or, if notice has already been given, during the remainder
      of the notice period); and

|(b) | the cost of contributions which
      would have been made by the Company towards the cost of retirement provision
      for the Executive during that period. Alternatively, the Company may, if
      it so chooses, make the contributions directly to the Executive’s pension
      arrangements to provide him with retirement benefits in respect of the unexpired
      portion of the notice period (or part thereof);

|(c) | the value of any bonus payment
      which would have been made under clause3. The payment made in respect of bonus under this clause 17.4 shall be
      not less than the amount which is equal to the bonus payment (if any) received
      by the Executive in respect of the bonus year preceding the Termination
      Date. Where the Payment in Lieu of Notice is in respect of a period which
      is less than one year, any payment in respect of bonus shall be adjusted
      downwards as applicable; and

|(d) | the cost of the other contractual
      benefits which the Executive would have been entitled to receive during
      that period. Alternatively the Company may, if it so chooses, continue to
      provide those contractual benefits during that period.                                                                                                                                                                                                                                                            

17.5    The Payment in Lieu
  of Notice shall be subject to such deductions as the Company may be required
  to make and shall be in full and final settlement of all claims the Executive
  may have against the Company or any Group Company (whether known or unknown)
  arising out of or in connection with the termination of the Employment and the
  Executive’s directorship of the Company or any Group Company. The Payment
  in Lieu of Notice may, at the Company’s discretion, be paid as a lump
  sum (within 10 working days of the last day of the Employment) or in equal monthly
  instalments from the Termination Date until the date which is twelve months
  after the Termination Date (or if notice had already been served before the

Termination Date, the remainder of the notice period)
  or if sooner, the date on which the Executive commences alternative employment.
  Any entitlement which the Executive has or may have under any share related
  incentive scheme shall be determined in accordance with the rules of such scheme.
  For the avoidance of doubt, (1) the Company is only to be taken as exercising
  the right given by this clause, and accordingly to be liable for the Payment
  in Lieu of Notice, if it gives the written notice referred to above explicitly
  invoking this clause; and (2) any delay or error in the Payment in Lieu of Notice
  shall not affect the lawfulness of a termination under this clause.

17.6     Upon termination
  of the Employment the Executive will at the Company’s request promptly
  resign in writing as a director of the Company and any Group Company and will
  promptly return to the Company any property of the Company and any Group Company.
  The Secretary of the Company is irrevocably authorised to sign letters of resignation
  on the Executive’s behalf if he fails to do so.

LIQUIDATED DAMAGES

18.1     If the Employment
  is terminated otherwise than in accordance with the terms of this Agreement
  (including, without limitation, if the Executive is constructively dismissed)
  the Company will pay to the Executive a liquidated sum calculated by reference
  to the Payment in Lieu of Notice set out in clause 17.4 (or clause 19.4 as appropriate)
  and paid subject to the terms of clause 17.5. The liquidated sum will be subject
  to such deductions as the Company may be required to make and will be in full
  and final settlement of any claims which the Executive has or may have against
  the company or any other Group Company arising out of or in connection with
  the Executive’s employment or its termination. In consideration for this payment
  the Executive agrees to remain bound by the post-termination restrictions in
  the Schedule to this Agreement.

18.2    For the purpose
  of clause 18.1 constructive dismissal shall include (but not be limited to):

|(i)   | the Executive’s removal from the
      office of director of the Company (other than by retirement by rotation
      pursuant to the Articles of Association of the Company) or from the position
      of Chief Financial Officer of the Company during the Employment without
      his consent on grounds insufficient to justify such removal; or

      which is more than 30 miles from Stockley Park, Uxbridge.                                                                                                                                                                        

CHANGE OF CONTROL

19.1    For the purposes
  of this clause 19.1:

Controlmeans the power of any person
  whether alone or together with any person acting in concert with him to control
  the composition of the board of directors of the Company or otherwise to secure
  whether by means of the holding of shares or the possession of voting power
  in relation to the Company or any other body corporate or by virtue of any powers
  conferred by the articles of association or any other document or agreement
  regulating the Company or any other body corporate that the affairs of the Company
  are conducted with the wishes of that person; and

Change of Controlmeans: (i) the
  disposal of all or substantially all of the Company; or (ii) the acquisition
  by any person whether alone or together with any person acting in concert with
  him of Control of the Company; but shall not mean an acquisition of Control
  of the Company by another company the shares of which, immediately following
  such an acquisition, are all held by the holders of the shares of the Company
  immediately prior to such an acquisition in materially the same proportion as
  they held shares in the Company immediately prior to such an acquisition.

19.2    If a Change of
  Control occurs the period of notice which the Company or the Executive is required
  to give to the other to terminate the employment in accordance with clause 17.1
  will be unaffected and will remain as 12 months.

19.3    For the period
  of 12 months following a Change of Control clause 17.4 shall be replaced by
  clause 19.4 unless clause 17.4 has already been operated prior to the Change
  of Control.

19.4    The Company may,
  in its sole discretion, also terminate the Executive’s employment by giving
  written notice to the Executive that it is exercising its discretion under this
  clause 19.4 to terminate the Employment with effect from such date as is specified
  in the notice (the Termination Date). In such a case the Company
  shall be obliged within 10 working days after the Termination Date to pay to
  the Executive a sum (the Payment in Lieu of Notice) equal to:

|(a) | the basic annual salary which the
      Executive would have been entitled to receive under the terms of this Agreement

      the operation of any applicable performance condition).

For the purposes of this clause 19.5, the Executive may be required to waive any share awards or share options which, in accordance with their terms, may vest or become exercisable after the Termination Date.

19.6    The
  Payment in Lieu of Notice shall be subject to such deductions as the Company
  may be required to make and shall be in full and final settlement of all claims
  the Executive may have against the Company or any Group Company (whether known

  invoking this clause; and (2) any delay or error in the Payment in Lieu of Notice
  shall not affect the lawfulness of a termination under this clause.

MITIGATION

  the purposes of paragraph 19 above, and not in any other circumstances, the
  payments set out (being payments made in accordance with this Agreement) will
  not be subject to mitigation, and will be paid irrespective of whether the Executive
  obtains alternative employment within the applicable notice period.

  shall be part of the Executive’s normal duties (whether or not during normal
  working hours and whether or not at the Executive’s normal place of work) at
  all times to consider in what manner and by what new methods or devices the

PRIVATE AND CONFIDENTIAL



Dear David

Appointment as Chairman

On behalf of mmO2 plc, I am writing to
  confirm the terms of your appointment as Chairman of the board of directors
  of the Company. This letter will replace your existing service agreement with
  the Company dated 13 June 2001 (the Service Agreement) with effect
  from 1 April 2003.

Appointment

1.     Your appointment
  as Chairman remains subject to the provisions of the Articles of Association
  of the Company for the time being in force and to any necessary resolutions
  of shareholders. Subject to this, it is anticipated that your appointment will
  be for the period ending no later than the date of the Company’s Annual General
  Meeting for the financial year 2003/2004 (the Expiry Date).
  However the appointment may be terminated at any time prior to the Expiry
  Date by either party giving to the other three months prior written notice.
  The appointment will terminate automatically on the Expiry Date without the
  need for either party to give notice.

2.     Upon termination
  of your appointment you will at the Company’s request promptly resign in writing
  as a director of the Company (and as a member of any committee of the Board)
  and of any Group company. The Company Secretary is irrevocably authorised to
  sign a letter of resignation on your behalf if you fail to do so.
