2.7  If the ITC specifies a particular European Community digital standard to be
     met in accordance with Section 142(3) of the 1996 Act, CTI shall (subject
     to its ability to obtain third party consents which CTI shall use its beat
     endeavours to obtain) employ a transmission system in compliance with that
     European Community digital standard within the time periods required by the
     ITC provided that any changes to the Technical Specification and/or the
     Services in consequence shall be authorised by BDB in accordance with the
     Change Control Procedure and if the implementation of material changes
     causes CTI necessarily to incur a material increase in costs, said material
     increase in costs shall be met by BDB, provided further that BDB shall not
     be charged more than its appropriate share of such costs.

2.8  If, during the continuance of this Agreement there should come into force a
     change in law or legally binding regulation applicable to this Agreement or
     the subject matter hereof, which necessitates (in order for CTI to comply
     with Clause 2.5.4) a change in the Services and/or increases in CTI's costs
     of providing the Services the parties shall consider such change in the
     Services or increase in costs pursuant to the Change

                                       13

 
      Control Procedure. BDB and CTI agree that BDB shall be responsible (to the
      extent there is any and it is necessarily incurred) for any increase in
      the material costs incurred by CTI of implementing or providing the
      Service in compliance with such change in law or legally binding
      regulation to the extent that such change in law or legally binding
      regulation is only applicable to the Services or is applicable to digital
      terrestrial television generally in which case BDB shall not be charged
      more than its appropriate share.

2.9   CIT shall, in relation to each BDB Multiplex provide the Services with a
      minimum end to end Accountable Availability from the BDB Interface to the
      output of each station of 99.9% except for those Stations identified in
      Schedule 7 Part III in respect of which the end to end Accountable
      Availability from the BDB Interface to the output of each Station will be
      a minimum of 99.8%. Such end to end Accountable Availability to be
      calculated as set out in Schedule 7.

2.10  CTI undertakes that it will use the skill and care of a diligent provider
      of distribution and transmission services in the provision of the
      Services, and discharge its obligations under this Agreement in accordance
      with best practice in the broadcasting industry.

2.11  CTI shall ensure that:

      2.11.1  no change of, reference to or use of a date later than 31 December
              1998 in the operation of the Network or the Network Status System
              will have an adverse effect on, or cause Services to cease to meet
              the Technical Specification; and

      2.11.2  without prejudice to the generality of Clause 2.11.1 above, the
              Network and the Network Status System will, in responding to two-
              digit date input and providing date output, resolve any ambiguity
              as to century in a manner which is consistent, clearly defined and
              apparent to the user.

2.12  CTI shall ensure that each Station satisfies the minimum level ERP (as
      specified in the Template) for each of Multiplexes B, C and D and will use
      all reasonable endeavors to maximise ERP at each Station within the
      maximum constraints specified in the Templates for each Station. CM shall
      demonstrate compliance with these obligations by the relevant transmission
      testing procedures described in Schedule 5 and Schedule 4 Part IV.

2.13  In the event that the population coverage predicted by the ITC for a
      Template is not reached ("COVERAGE LOWS") despite CTI's compliance with
      Clause 2.12, CTI will use all reasonable endeavours to overcome the
      Coverage Loss with practical solutions (to be considered through the
      Change Control Procedure) and will provide all reasonable assistance to
      BDB in any consequential discussions with the ITC. If such Coverage Loss
      is due to failure of CTI to comply with Clause 2.12, CTI will be
      responsible for any costs and expenditure incurred in correcting such
      failure and providing assistance

                                       14

 
      to BDB. In all other circumstances where BDB wish to have such corrective
      works performed, the additional expenditure required will be met by BDB.

      Use of Fibre Distribution Network

2.14  The Charges are based on the use by CTI of the Fibre Distribution Network.
      British Telecommunications Plc ("BT") has offered to provide CTI with
      fibre distribution services which will enable CTI to provide the
      Distribution Services using the Fibre Distribution Network.

2.15  The price at which CTI has been offered fibre distribution services by BT
      and therefore the charges set out in Part 1 of Schedule 2 are based on a
      new tariff for a bespoke distribution network which can only be made
      available if taken up by the operators of a minimum number of digital
      terrestrial television multiplexes and CTI Is waiting confirmation from BT
      that it can make the fibre distribution services available to CTI on the
      basis of the tariff. However, CTI agrees to use all reasonable endeavors
      to procure the availability of the Fibre Distribution Network as
      contemplated in this Agreement.

2.16  If, during the first six months from the date hereof, the price at which
      CTI is supplied by BT with the Fibre Distribution Network is materially
      increased or the Fibre Distribution Network is no longer available either
      because the operators of the multiplex used to transmit the digital
      services of Channel 3 and Channel 4 or the BBC elect not to use the
      bespoke distribution network contemplated in Clause 2.15 or as a result of
      a regulatory intervention by, or other requirements of, the Director
      General of Telecommunications, the Change Control Procedure shall be
      invoked to discuss the implications of the intervention or other
      requirements and, if BDB elects to continue with the Fibre Distribution
      Network, BDB acknowledges that the Charges will be amended accordingly
      (provided that CTI shall use all reasonable endeavors to reduce the amount
      of any increase and shall follow all reasonable instructions of BDB
      relating to the use of an alternative distribution system) and that in the
      absence of such amendment CTI shall not be obliged to provide the Fibre
      Distribution Network.

2.17  If, during the first six months from the date hereof, BT is unable to make
      the fibre distribution services available to CTI as contemplated in Clause
      2.14 and 2.15 and CTI can therefore cannot commit to providing the Fibre
      Distribution Network. BDB shall have the option to require CTI to
      substitute the Satellite Distribution Network on the basis set out in
      Annex 1 (the provisions of which shall be substituted for the equivalent
      provisions of Schedules 2, 3, 6 and 11) and the Satellite Distribution
      Network shall become the Distribution Network for the purposes of this
      Agreement.

3.    OWNERSHIP OF THE NETWORK AND SCOPE OF THIS AGREEMENT

3.1   The Network shall be procured and/or constructed, operated and maintained
      by CTI to provide, inter alia, the Services to BDB.

                                       15

 
3.2   Subject to the provisions of Clause 3.3 all equipment and services
      required by CTI to provide the Services (including but not limited to the
      Sites, buildings, plant, the Distribution Network and the Transmission
      Network) will be acquired, obtained or procured by CTI at its own cost.

3.3   [*].

3.4   The parties will ensure their financial advisers co-operate to seek an
      early resolution to the manner in which the arrangements contemplated in
      Clause 3.3 are best achieved.

3.5   Subject to Clauses 3.3 and 18.11, as between CTI and BDB, BDB shall have
      no ownership of any part of the Network.

3.6   This Agreement relates, inter alia, to the rollout of the 81 Stations
      specified in Schedule 8. If, without hereby creating any binding
      obligation, the parties agree to include any Additional Stations in the
      Network the terms on which such Additional Stations shall be provided,
      including the order and speed of the rollout of the Subsequent Stations
      shall be agreed in accordance with the Change Control Procedure save that
      the Charges attributable to such Additional Stations shall be calculated
      in accordance with the provisions of Schedule 12.

3.7   The Exclusive Equipment shall not be used by CTI to provide services to
      itself or to any third party without the prior written consent of BDB.

4.    ROLL-OUT OF THE STATIONS AND DISTRIBUTION NETWORK

4.1   CTI will construct and/or procure the construction of the Transmission
      Network in accordance with best industry practice in the broadcasting
      industry.

4.2   ITC shall bring each of the Stations into Operational Service on its Ready
      for Service Date. The Initial Site Service Dates, subject to the
      provisions of this Agreement, are as Follows:

      4.2.1  for the Phase I Stations, the Initial Site Service Date shall be
             the date 12 months from the grant of the Multiplex Licences
             provided that CTI shall use its reasonable endeavors to bring each
             of those Phase I Stations into

[*] indicates where text has been omitted pursuant to a request for confidential
    treatment. The omitted text has been filed with the Securities and Exchange
    Commission separately.

                                      16

 
             Operational Service on its Target Site Service Date or as soon as
             practicable thereafter;

      4.2.2  for each of the Phase II and Phase III Stations, the initial Site
             Service Date shall be the Target Site Service Date as extended by a
             period equal to the period of time between 30 September 1998 and
             the latest Initial Site Service Date for a Phase I Station agreed
             between the parties pursuant to Clause 4.2.1 or 4.3.1, as the case
             may be, provided that CTI shall use its reasonable endeavors to
             bring each of those Phase II and Phase III Stations on its Target
             Site Service Date.

4.3   Without prejudice to Clause 4.2:

      4.3.1  no later than 30 days after the grant of the Multiplex Licences,
             CTI and BDB will consider, in good faith, whether the Initial Site
             Service Dates for the Stations should be revised (taking into
             account, amongst other things, the obligation of CTI to use
             reasonable endeavors to bring each of the Stations into Operational
             Service on its Target Site Service Date; the requirements of BDB
             and of the digital terrestrial television industry generally,
             including the requirements of CTI and NTL to have sufficient time
             to roll-out the Stations in order to meet agreed Ready for Service
             Dates; and any Advance Works carried out); and

      4.3.2  not less than 90 days before each initial Site Service Date, CTI
             and BDB will again consider, in good faith, whether that Initial
             Site Service Date should be revised.

      If CTI and BDB agree to the revision of an Initial Site Service Date
      pursuant to this Clause 4.3 then BDB shall, having regard to its
      obligations under the Multiplex Licences, and where relevant, use its
      reasonable endeavors to seek the consent of the ITC (and any other
      regulatory authority having jurisdiction) to an Amended Site Service Date.
      If CTI and BDB agree and, where relevant, the ITC (and any other
      regulatory authority having jurisdiction) consent to the Amended Site
      Service Date, then such date shall be substituted as the Ready for Service
      Date.

4.4   If, pursuant to Clause 4.3, CTI and BDB decide not to revise an Initial
      Site Service Date, or fail to reach agreement relating to any proposed
      revision to an Initial Site Service Date, or the ITC (or any other
      regulatory body having jurisdiction) refuses to consent to any revision to
      a Start of Service Date proposed as a consequence then that Initial Site
      Service Date shall remain the Ready for Service Date unless, in the event
      of the ITC refusing to consent to a revision to the Start of Service Date,
      CTI and BDB nonetheless agree an Amended Site Service Date, in which case
      said Amended Site Service Date shall become the Ready for Service Date.

4.5   If at any time an event occurs or circumstances arise which may delay the
      bringing into Operational Service of any Station on the relevant Ready for
      Service Date, then

                                       17

 
      CTI shall as soon as reasonably practicable (and in any event within 5
      Business Days of CTI becoming aware of the event or circumstances in
      question), notify BDB of that fact in writing. Such notification shall set
      out:

      4.5.1  the nature of the event or circumstances and whether they have
             arisen as a result of any of the causes set out in Clause 4.7;

      4.5.2  a description of the steps, if any, which CTI has identified are
             necessary to rectify the matter and bring the Station into
             Operational Service on the relevant Ready for Service Date or as
             soon as practicable thereafter; and

      4.5.3  the likely effect of the event or circumstances on the
             achievability of the relevant Ready for Service Date.

4.6   Following receipt by BDB of any notification pursuant to Clause 4.5, CTI
      and BDB shall discuss in good faith:

      4.6.1  actions which can be taken to rectify the matter; and

      4.6.2  any proposed change to the relevant Ready for Service Date.

4.7   Notwithstanding the foregoing, if any event or circumstance notified by
      CTI under Clause 4.5 is, or arises as a result of, one or more of the
      following:

      4.7.1  a Force Majeure Event;

      4.7.2  any material breach by BDB of any material obligations of BDB under
             this Agreement which prevents CTI from performing the relevant
             obligation under this Agreement; or

      4.7.3  compliance with any applicable law, the mandatory requirements of
             any national or supranational regulatory authority, the Radio
             Regulations or any other applicable statutory obligations
             (including, for the avoidance of doubt, frequency planning or
             international frequency clearance issues);

      then, such events shall be deemed, for the purposes of this Agreement, to
      be outside the control of CTI save to the extent that the event arose (in
      the case of an event under Clause 4.7.3 only) as a result of any breach of
      this Agreement by CTI. Accordingly, CTI shall have no liability to the
      extent delay arises from such events, whether under Clause 6.1 or
      otherwise, to pay any Delay Rebate, damages or other compensation to BDB
      as a result of the relevant Station not being ready for Operational
      Service by the Ready for Service Date as a result of such events and that
      Ready for Service Date shall be extended to the earliest practicable
      Amended Site Service Date on which BDB requires and CTI can, using its
      best endeavors, make the Station available for Operational Service in the
      light of the relevant event. The provisions of Clause 5 shall apply to
      determine whether the relevant Station is ready for Operational Service by
      the Amended Site Service Date.

                                       18

 
4.8   The costs (subject to Clause 17.7) of circumventing or rectifying the
      consequences of the cause of delay set out in Clause 4.7 shall, save to
      the extent that the event arose (in the case of any event under Clause
      4.7.3 only) as a result of any breach of this Agreement by CTI be borne by
      BDB.

5.    TESTING

5.1   CTI shall, at its cost, test the Network and test each Station prior to
      its Ready for Service Date in accordance with Part I of Schedule 5 and all
      reasonable instructions of BDB. All Transmission Testing shall be
      conducted in accordance with any applicable law, licence or regulatory
      requirement (including, without limitation, the ITC Guidance Note on Test
      Transmissions).

5.2   Each Station shall be made available for testing prior to its Ready for
      Service Date as soon as reasonably required by BDB.

5.3   CTI shall provide BDB with reasonable advance notice of any Transmission
      Testing and BDB or its authorised representatives shall have the right to
      attend and monitor any Transmission Testing.

5.4   As soon as reasonably practicable before the Ready for Service Date for a
      Station. CTI will confirm to BDB that the Station is ready for Operational
      Service. Such confirmation shall be in writing and shall be accompanied by
      a full set of test results for each station showing that the Transmission
      Testing has been completed successfully. A Station shall be ready for
      Operational Service when it has satisfied the Transmission Testing.

5.5   BDB shall have the right to verify the results of the Transmission
      Testing. The costs of such verification shall be met by BDB save where
      such verification reveals that the Station in question has not satisfied
      the Transmission Testing in which case the costs of the verification and
      any subsequent Transmission Testing shall be met by CTI.

5.6   Between the Ready for Service Date and the Actual Site Service Date of
      each Station CTI shall perform such Test Transmissions from that Station
      as may reasonably be requested by BDB such Test Transmissions to be
      carried out at such times and for such periods as BDB may reasonably
      require. The costs of the Test Transmissions shall be met by CTI. BDB
      shall provide such BDB Signals or other material as are agreed with CTI
      for the purpose of enabling Test Transmissions, to be carried out.

6.    CONSEQUENCES OF FAILURE TO ACHIEVE READY FOR SERVICE, DATES

6.1   Subject to Clauses 4.2 and 6.2, if any Station is not ready for
      Operational Service by the relevant Ready for Service Date, then CTI shall
      be liable to pay a Delay Rebate in an amount in respect of the relevant
      Station calculated in accordance with Part II of Schedule 7, for the
      period from noon on the relevant Ready for Service Date to the Actual Site
      Service Date. The Delay Rebate shall be credited against the Charges

                                       19

 
      payable in respect of the first month of the Year following the Year in
      which the Ready for Service Date originally fell.

6.2   The Distribution Network for each Station shall be available for
      Operational Service no later than the Ready for Service Date for that
      Station. With respect to each Phase I Station, if the Distribution
      Services are provided using the Fibre Distribution Network, CTI shall use
      all reasonable endeavors to ensure that the Distribution Network for that
      Phase I Station is ready for Operational Service on the date falling [*]
      days before the Start of Service Date for that Phase I Station. For the
      purposes of calculating Delay Rebate, due solely to failure to make the
      Fibre Distribution Network for a Phase I Station available the Ready for
      Service Date for that Phase I Station shall be deemed to be the date [*]
      days before the Start of Service Date for that Phase I Station and CTI
      shall not be liable in breach of contract for any failure to have the
      Fibre Distribution Network for that Phase I Station ready for Operational
      Service prior to that date.

6.3   If BDB elects to employ the Satellite Distribution System pursuant to
      Clause 2.17, CTI shall ensure that the satellite space segment necessary
      to provide the Distribution Services is available for use by CTI as from a
      date to be agreed between the parties and, in any event, no later than 60
      days prior to the first Start of Service Date.

7.    MODIFICATIONS TO EXISTING ANALOGUE TRANSMISSION SYSTEMS

7.1   CTI shall, at its own cost and in a proper manner carry out or procure
      that the work described in the Agreed Impact Schedule is carried out as
      requested in order to enable Operational Service to commence from each
      Station an the relevant Ready for Service Date and subject to Clause 7.3
      in compliance with the Multiplex Licences and shall promptly carry out any
      other work agreed by BDB and CTI to effect changes required to the
      analogue transmitter network as a consequence of transmission on the
      frequencies allocated to the BDB Multiplexes.

7.2   In the event that any analogue modification works are required to overcome
      interference caused by or as a direct consequence of the Network to
      analogue television broadcast services in addition to those works
      identified in the Agreed Impact Schedule, then CTI will provide details of
      the works to be carried out, the costs and estimated duration of such
      works and such other information as BDB may reasonably require and CTI
      will, where required by BDB, carry out such works and meet the reasonable
      costs and expenses (provided that BDB shall not be charged more than its
      appropriate share) of the carrying out of such works agreed by BDB (the
      "EXPENDITURE").[*]

7.3   Nothing in this Agreement shall impose any obligation on CTI to carry out
      domestic returning or antenna alignment or to establish a help desk or
      similar facility to deal

    treatment. The omitted text has been filed with the Securities and Exchange
    Commission separately.

                                      20

 
       with queries or complaints from the general public in connection with the
       provision of the Services.

8.     SECURITY AND SITES

8.1    CTI will take and procure that its sub-contractors take all such security
       measures in relation to the Network (including, but not limited to at the
       Sites) as would normally be taken by an experienced distribution and
       transmission services provider including, but not limited to, security
       measures at the Stations to protect against forcible entry and damage by
       vandals and burglars using hand operated tools, including protection of
       doors and windows in Station buildings, protection of antenna feeders by
       scaled underground ducting, steel tube or trunking protection of feeds
       located above ground to a height above anti-climbing guards on the
       antenna support structures, and intruder alarms at all monitored
       unattended Stations. CTI shall regularly review the efficacy of such
       security measures and shall take additional security measures at Stations
       allocated high priority status by CTI as set out in Schedule 8, such
       additional security measures to include, without limitation, additional
       monitored security fencing and security cameras.

8.2    Where CTI is not the owner of a Site and the owner of that Site wishes to
       terminate CTI's right to use the Site, CTI will notify BDB of such
       intended termination as soon as reasonably practicable and shall consult
       with and where practicable pay due heed to any recommendations made by
       BDB. CTI shall, in any event make all necessary arrangements for the
       provision of a substitute station which shall become a Station for the
       purposes of this Agreement, subject to receiving the consent of ITC (and
       other relevant regulatory authorities) and BDB (such consent riot to be
       unreasonably withheld by BDB). CTI shall use all reasonable endeavors to
       ensure that this event does not give rise to a material deterioration of
       the level or quality of the Services.

9.     INDUSTRY LIAISON AND SPECTRUM MANAGEMENT

9.1    CTI will throughout the Term:

       9.1.1   work closely with BDB and all relevant third parties in providing
               its technical expertise and support (including, but not limited
               to, BDB's chosen systems integrator, the ITC, the
               Radiocommunications Agency. NTI., other relevant organisations,
               other multiplex distribution and transmitter network services
               operators, receiver, set top box and other equipment
               manufacturers) with a view to achieving the interoperability of
               services and equipment and the successful launch of digital
               terrestrial television in the UK;

       9.1.2   liaise with relevant organisations and groups such as the UK

               CTI is permitted or invited to attend) relating to digital
               terrestrial television broadcasting; and

                                       21

 
       9.1.4   assist BDB where reasonably requested in preparing written
               representations or submissions to regulators, industry or
               government bodies or working groups relating to the subject
               matter of this Agreement, including representations or
               submissions relating to digital terrestrial television
               broadcasting.

9.2    Throughout the Term, CTI will co-operate with and assist BDB where
       reasonably requested by it, in relation to questions of spectrum

       11.7.4  CTI shall (subject to BDB indemnifying CIT against the cost or
               damages incurred thereby):

               (a)  take any action and institute any proceedings, and give any
                    information and assistance BDB may reasonably request to:

                    (i)  dispute, resist, appeal, compromise, defend, remedy or
                         mitigate the matter; or

                    prior written approval (such approval not to be unreasonably
                    withheld or delayed).

11.8   Nothing in this Clause 11 in any way restricts or limits CTI's general
       obligation at law to mitigate a loss which it may incur as a result of a
       matter giving rise to a claim pursuant to Clause 11.6.

       Signals as a result of any breach of Clause 11.4 or otherwise as the
       result of any applicable law, or regulatory requirement (including but
       not limited to compliance with a direction of the ITC) for any reason,
       CTI shall, upon receipt of written notification from BDB or

                                       24

 
       earlier if pursuant to a legal requirement, suspend provision of the
       Services for the requisite period notified by BDB (or such longer period
       as necessary pursuant to the legal requirement) provided that in doing so

13.3   Any complaints, disputes or problems (each an "Issue") relating to this
       Agreement will be escalated as set out in this Clause 13.3:

       13.3.1  if an Issue is not resolved to the satisfaction of either party
               within 30 days of both parties having first been aware of it,
               then either party may refer the Issue to the Service Management
               Board;

       13.3.2  if an Issue is referred to the Service Management Board, then
               each party must procure that their representatives on the Service
               Management Board discuss the issue in good faith at the next
               meeting of the Service Management Board with a view to resolving
               it. Either party may convene a meeting of the Service Management
               Board to be held within 14 days of an Issue being referred to it.
               If the Issue is not resolved to the satisfaction of either party
               within 7 days of the meeting of the Service Management Board,
               then either party may refer the Issue to the Director of Options
               of BDB, in the ease of BDB ("THE BDB NOMINEE") and to the Chief
               Operating Officer of CTI in the case of CTI ("THE CTI NOMINEE");

                                       26

 
       13.3.3  if the Issue is referred to the BDB Nominee and the CTI Nominee,
               then each party must procure that their representatives discuss
               the Issue in good faith as soon as reasonably practicable and in
               any event, within 14 days of the meeting of the Service
               Management Board referred to in Clause 13.3.1;

       13.3.4  if an Issue which relates solely to matters of an engineering or
               technical nature is not resolved pursuant to Clause 13.3.3,
               either party may refer it (with a request that the person
               appointed does not have a conflict of interest) for adjudication
               to the President for the time being of the Institution of
               Electrical Engineers, or his nominee. The President or his
               nominee shall act as an expert, not an arbitrator. The party
               referring any Issue for adjudication must deliver to the expert
               and the other party a notice setting out the matters in dispute
               and any relevant supporting evidence. The other party shall be
               entitled to reply to the notice and such evidence, delivering
               such reply to the expert and the party referring the Issue.
               Otherwise, the expert shall be entitled to decide on the
               procedure he or she wishes to adopt. Any determination of the
               expert must be in writing and shall be final and binding on both
               parties failing any manifest error on the face of the decision.
               Unless the expert determines otherwise, both parties will bear
               their own costs of the determination and half the costs of the
               expert;

       13.3.5  if an Issue which does not relate solely to matters of an
               engineering or technical nature is not resolved pursuant to
               Clause 13.3.3, either party may refer it to mediation in
               accordance with the Centre for Dispute Resolution procedures then
               in force. The other party shall not be obliged to attend such
               mediation. If after 30 days of the matter being referred to
               mediation or if either party believes that mediation has not
               resolved the Issue or it believes that it is not appropriate to
               resolve the issue by mediation or the other party has refused to
               attend mediation, then either party may proceed to litigation.
               Unless agreed otherwise, each party will bear their own costs of
               the mediation and half the costs of any third party involved;

       13.3.6  except where clearly prevented by the nature of the Issue, the
               parties shall continue performing their respective obligations
               under this Agreement while any Issue is escalated in accordance
               with this Clause 13.3. Without prejudice to the generality of the
               foregoing, BDB shall continue to pay the Charges.

               necessary to do so for essential maintenance at any of the
               Stations provided that CTI shall use all reasonable endeavours to
               reduce the impact of such emergency or essential maintenance
               works or repairs on the provision of the Services (including,
               without limitation, by performing such essential maintenance
               works or repairs at times when the audience for the services
               transmitted from the relevant Stations are low);

       15.1.3  CTI may also interrupt the DTT Transmission Services or depart
               from the Technical Specification in order to carry out any
               planned installation works on the antenna support structures at
               any of the Stations;

       15.1.4  CTI shall provide to BDB a schedule of planned maintenance on
               antennas and structures on a rolling twelve month basis as set
               out in Schedule 4 Part III;

       and, save in cases of emergency, CTI will use all reasonable endeavours
       to agree times and duration of any interruption or impairment of the
       Services with the BDB Representative and use all reasonable endeavours to
       minimise the duration of any such interruption or impairment.

15.2   In cases where the Services are provided from a Third Party Site, BDB
       acknowledges that CTI may be required by the Site Owner to interrupt the
       DTT Transmission Service from the Third Party Site, on reasonable prior
       notice in the case of planned access or without notice in cases of
       emergency, so that safe access may be gained to any mast or the Equipment
       at the Third Party Site. CTI shall procure that the Site Owner does not
       interrupt, or require CTI to interrupt, the BDB Transmission Service in
       such circumstances save:

       15.2.1  in the event of any life or property threatening emergency;

       15.2.2  where any interference caused by the Equipment is creating
               significant degradation to the services of the users of the Third
               Party Site and the degradation still exists after the Site Owner
               has taken all reasonable measures to contact and inform CTI of
               such degradation and, where practicable to do so, the Site Owner
               has allowed CTI a reasonable period to remedy any such
               Interference;

       15.2.3  it is required to do so by the Department of Trade and Industry
               (or its statutory successor or equivalent); or

       15.2.4  with the agreement and at the request of CTI (which shall not be
               forthcoming without BDB's consent, such consent not to be
               unreasonably withheld or delayed) 

                                       30

 
      and CTI shall further procure that, where practicable, such interruptions
      occur at times and for duration reasonably agreed with BDB and during
      periods when the audience receiving the BDB Signals is anticipated to be
      low.

15.3  In the case of a Transmission Fault which cannot be dealt with by remote
      control, CTI shall ensure that the time from the occurrence of the
      Transmission Fault until the time an Engineer attends at the site of the
      Transmission Fault or other impairment does not exceed the relevant
      Response Time.

15.4  CTI shall ensure that action is taken to rectify any Transmission Fault or
      other impairment as soon as practicable after the time of the occurrence
      of the Transmission Fault or other impairment.

15.5  CTI shall obtain, commission and provide at CTI's expense the Emergency
      Reserve Equipment and the Disaster Recovery Systems and such other
      equipment and services as would normally be held by a prudent distribution
      and transmission services operator to restore distribution and
      transmission services similar to the Services in the event of loss of the
      same.

15.6  CTI shall permit BDB or its authorised representative by reasonable prior
      arrangement to visit any of the Stations accompanied by a representative
      of CTI, for the purpose of inspecting that part of the Network located
      there. In such circumstances CTI shall be entitled to invoice BDB, as an
      additional charge, its reasonable attendance costs of a member of the
      local maintenance team calculated in accordance with CTI's standard
      ratecard. This charge shall not apply before the Start of Service Date of
      each Station. BDB shall itself and shall procure that its subcontractors,
      comply with all applicable Health and Safety legislation and regulations
      and any code of practice or safety at work rules operated by CTI (or NTL)
      at the applicable Station.

16.   CHANGE CONTROL

16.1  Except as expressly set out in this Agreement, any changes to this
      Agreement or any of the Services proposed by CTI shall be dealt with in
      accordance with Schedule 1, Part I.

16.2  Except as expressly set out in this Agreement, any changes to this
      Agreement or any of the Services proposed by BDB shall be dealt with in
      accordance with Schedule 1, Part II.

17.   CHARGES, SAVINGS, PAYMENT AND BILLING

      Charges and Payment for the Services

17.1  In consideration for the satisfactory performance by CTI of its
      obligations under this Agreement BDB shall pay the Charges (in Pounds
      Sterling) in accordance with the payment timetable and instalment
      provisions set out in Schedule 2.

                                       31

 
17.2  Upon this Agreement coming into full force and effect, Advance Payments
      paid by BDB pursuant to the Pre-Contract Funding Agreement shall be set
      off against the equivalent monthly charges which would have been payable
      pursuant to this Agreement had this Agreement been in full force and
      effect from the date hereof.

17.3  In the event that the Commencement Date occurs between 1 October 1998 and
      31 December 1998 and in consequence CTI incurs any material additional
      operational expenditure over the Term, BDB shall bear the cost of such
      increase, the method of recovery to be determined under the Change Control
      Procedure. If this Agreement has not become unconditional in accordance
      with its terms prior to 1 January 1998, then:

      17.3.1  In the event that the Term will extend beyond 31 December 2010,
              for the period commencing 1 January 2011 until the expiry of the
              Term ("RELEVANT PERIOD"), CTI shall be entitled to recover Charges
              at a fair market price in respect of the Relevant Period to be
              agreed between the parties. In default of agreement between the
              parties as to fair market price, the provisions of Clauses 18.2
              and 18.3 shall apply mutatis mutandis as if references in those
              Clauses to the Extended Term were references to the Relevant
              Period; and

      17.3.2  the Charges shall be adjusted by an amount equal to any bona fide
              material overall variation (A "COSTS VARIATION") to CTI's third
              party costs or operational costs relating to the provision of the
              Services to be agreed by the parties. In default of agreement
              between the parties as to the amount of that Costs Variation, the
              provisions of Clauses 18.2 and 18.3 shall apply mutatis mutandis
              as if references in those Clauses to the Extended Period were
              references to the Relevant Period and references to fair market
              price were to the Costs Variation.

17.4  The Charges are based on the provision of the Services and the roll-out of
      the Stations as set out in this Agreement. If the roll-out of the Stations
      is revised, the Charges shall be adjusted by CTI by an amount agreed
      pursuant to the Change Control Procedure.

17.5  CTI will operate a transparent open book approach to the provision of the
      Services, including, but not limited to, by providing BDB with access to
      CTI's information regarding CTI's costs in acquiring the Equipment,
      constructing or procuring the Network and providing the Services.
      Information provided under this Clause will be provided to BDB pursuant to
      Clause 17.6 or at such other times as reasonably requested by BDB.

       Savings

17.7   Throughout the Term CTI will work with BDB, other multiplex licensees and
       equipment and service providers to seek to reduce CTI's costs in
       providing the Services. To the extent that any overall savings are
       achieved which have not (in respect of the Agreed Proportion thereof)
       been applied by CTI to defray increased or unforeseen costs in lieu of
       the Contingency Amount, CTI will reduce the Charges by an amount equal to
       the Agreed Proportion of such savings such reduction to be implemented in
       such a manner as to avoid financial disadvantage to CTI caused by any
       changes to the instalment payment of the Charges.

17.8   CTI shall use its reasonable endeavours to mitigate costs it may incur
       pursuant to Clauses 4.7 and 4.8 and, if CTI makes an overall saving in
       its costs as a result of a delay pursuant to Clause 4.7 such overall
       savings shall be passed in their entirety on to BDB by way of a reduction
       to the Charges the manner of implementation of which shall be agreed
       through the Change Control Procedure.

17.9   If CTI makes any overall saving in its costs as a result of the
       suspension of the provision of the Services pursuant to Clause 11.10, it
       shall pass on the benefit of such overall savings to BDB in its entirety
       by way of a reduction to the Charges, the manner of implementation of
       which shall be agreed through the Change Control Procedure.

       Invoices

17.10  CTI will invoice BDB monthly in arrears, with invoices to be issued at
       the end of each month. The first such invoice will be issued at the end
       of the first full month since this Agreement became unconditional in
       accordance with its terms. All invoices will be addressed to Director of
       Operations, at the address in Clause 24.

17.11  Each invoice rendered by CTI shall be accompanied by such billing
       information and be in such format as BDB may reasonably require and as
       may be required by law or regulatory requirements.

17.12  Except in the event of a disagreement as to the amount due, correctly
       prepared and submitted invoices shall be paid by BDB on the 13th day
       following the date of CTI's

                                       33

 
       invoice (the "DUE DATE"). Invoices shall be payable by electronic funds
       transfer to Royal Bank of Scotland plc, Corporate Banking Office, P.O.
       Box 450, 5-10 Gt. Tower Street, London, EC3P 3HX (account no. 20071038,
       sort code 16-04-00) or in such other manner as CTI may reasonably direct
       and shall be paid in full, subject only to Clause 17.14, without any
       withholding, set-off or deduction whatsoever.

17.13  CTI may charge interest on outstanding amounts payable to CTI from the
       Due Date until payment in full is received by CTI at a rate equal to 2
       per cent. per annum above the base lending rate of the Royal Bank of
       Scotland plc as current from time to time whether before or after
       judgement. Interest accrues daily and will continue to accrue on any
       unpaid amounts notwithstanding termination of this Agreement for any
       cause.

17.14  Subject to Schedule 7, if any Service Credits or Delay Rebate are payable
       hereunder, such Service Credits and Delay Rebate shall be deducted from
       the Charges by an adjustment made by CTI to the first payment due in
       respect of the Year following the Year in which the Service Credits or
       Delay Rebate accrued. Any Service Credits or Delay Rebate payable in
       respect of the final Year shall be paid by CTI to BDB no later than 30
       days after the termination or expiry of this Agreement.

18.    TERM, TERMINATION AND SUSPENSION

       Commencement and the Term

18.1   This Agreement shall come into force as provided in Clause 2.1 and unless
       terminated earlier shall continue in force for the Term.

18.2   BDB shall have the option to extend the Term for a further period of not
       less than 6 years but not exceeding 12 years (the "EXTENDED TERM") by
       giving notice in writing to CTI not less than 12 months' prior to the
       expiry of the Term. Such Extended Term to be on the then current terms of
       this Agreement save that the Charges shall be revised to a level agreed
       by the parties to represent a fair market price for the Services to be
       provided during the Extended Term having regard amongst other things to
       the availability of the existing Network and Equipment and any expected
       replacement costs thereof.[*]

       Termination

18.4   Subject to Clause 18.5, if either party is in material breach of this
       Agreement (the "BREACHING PARTY"), the other party may, by notice in
       writing, terminate this Agreement by giving three months' prior written
       notice.

18.5   In the case of a material breach of this Agreement which is remediable,
       the other party may serve a notice on the Breaching Party giving details
       of the breach and requiring it to remedy the breach within 30 days of
       receipt of the notice. If the Breaching Party fails to remedy the breach
       within the period specified in the notice then the other Party may
       terminate this Agreement by giving two months' prior written notice
       during which BDB, if the other party, may suspend taking the Services and
       payment of the Charges to CTI.

18.6   BDB may terminate this Agreement on 30 days written notice if any TA
       Licences are suspended or revoked thereby preventing the lawful
       performance by CTI of this Agreement.

18.7   In the event of a suspension or revocation of a right to use a frequency
       under a WTA Licence:

       18.7.1  CTI shall endeavour to reverse the effect of the suspension or
               revocation;

       18.7.2  if CTI cannot implement Clause 18.7.1, the parties shall attempt
               to agree on whether to exclude the affected Station from the
               Services and the consequent reduction in the Charges; and

       18.7.3  in the event that neither of the above are achieved within 30
               days or any longer period reasonably agreed by the parties, BDB
               may terminate this Agreement on 30 days written notice provided
               that the effect of the suspension or revocation is such as to
               cause the ITC to revoke or threaten to revoke the Multiplex
               Licences or otherwise has the effect that BDB is deprived of
               revenue equivalent to three month's worth of Relevant Revenue.
               For the purpose of this clause Relevant Revenue means 2% of BDB's
               revenue for the twelve months preceding the event.

18.8   Either party may terminate this Agreement with immediate effect by
       written notice if:

       18.8.1  a liquidator, administrative receiver, administrator or receiver
               is appointed (other than for the purpose of an amalgamation or
               reconstruction, the terms of which have been previously approved
               by the party having the right to terminate (such approval not to
               be unreasonably withheld or delayed in the

                                       35

 
               case of a solvent amalgamation or reconstruction)) in respect of
               the whole or a material part of the assets and/or undertaking of
               the other party; or

       18.8.2  the other party enters into an arrangement or composition with
               its creditors, or if it becomes unable to pay its debts within
               the meaning of section 123 of the Insolvency Act 1986.

       Suspension

18.9   CTI may suspend provision of the Services in whole or in part until
       further notice on notifying BDB in writing with immediate effect from
       receipt by BDB of the notice on the occurrence of any of the following (a
       "SUSPENSION EVENT"):

       18.9.1  BDB is in material breach of this Agreement which, in the case of
               a breach capable of remedy, BDB has failed to remedy within 30
               days of receipt of notice from CTI to do so; or

       18.9.2  any licence required by law to be held by BDB is cancelled,
               revoked, not renewed, suspended or otherwise terminated by the
               relevant licensing body thereby preventing the lawful performance
               by CTI of this Agreement;

       18.9.3  The suspension of this Agreement is required in order to comply
               with a mandatory order, instruction or request of any government
               minister, The Home Office, The Channel Islands, Isle of Man
               Authorities, an emergency services organisation or any other
               competent administrative authority.

       Provided that BDB will nevertheless remain liable for its payment
       obligations under the Agreement (subject to CTI mitigating its losses)
       and CTI's right to suspend the provision of the Services pursuant to this
       Clause shall only apply in respect of any particular Station or BDB
       Multiplex to the extent that and for so long as the Suspension Event
       occurred in respect of that Station or BDB Multiplex. Subject to BDB
       continuing to meet its payment obligations as aforesaid CTI agrees that
       the right of suspension, where exercised, shall be CTI's sole remedy for
       any breach in respect of which the right to suspend has been exercised.
       If CTI makes any overall savings, in its costs as a result of suspension
       pursuant to this Clause 18.9 it shall pass the benefit of these savings
       to BDB by crediting such saving as a reduction in the Charges, the manner
       of implementation of which shall be agreed through the Change Control
       Procedure.

       Consequences of Termination

18.10  Expiration or termination for whatever reason of this Agreement will not
       affect any rights of the parties which have accrued prior to its
       expiration or termination including, without limitation, any right to
       claim damages for breach of this Agreement.

                                       36

 
18.11  If pursuant to Clauses 18.4, 18.5, 18.7, 18.8 or 20.2 BDB becomes
       entitled to and does exercise its right to terminate this Agreement it
       may also exercise a right to purchase Exclusive Equipment in accordance
       with and subject to the provisions of Schedule 10.

19.    WARRANTIES

19.1   Each party warrants to the other that it has full power and authority to
       enter into and perform its obligations under this Agreement.

19.2   CTI warrants to BDB that the use of the Network and the Services by BDB
       in accordance with this Agreement will not place BDB in breach of any
       law, regulation, direction, permission, waiver, consent, registration,
       approval or other authorisation.

20.    FORCE MAJEURE

20.1   If a party (the "AFFECTED PARTY") is prevented, hindered or delayed from
       or in performing any of its obligations under this Agreement by a Force
       Majeure Event:

       20.1.1  the Affected Party's obligations under this Agreement are
               suspended from notification of the event in accordance with
               Clause 20.1.2 while the Force Majeure Event continues but only to
               the extent that it is so prevented, hindered or delayed:

       20.1.2  immediately after the start of the Force Majeure Event the
               Affected Party shall notify the other party in writing of the
               Force Majeure Event, the time and date on which the Force Majeure
               Event started and the effects of the Force Majeure Event on its
               ability to perform its obligations under this Agreement;

       20.1.3  the Affected Parry shall make all reasonable efforts to mitigate
               the effects of the Force Majeure Event on the performance of its
               obligations under this Agreement; and

       20.1.4  immediately after the end of the Force Majeure Event, the
               Affected Party shall notify the other party in writing that the
               Force Majeure Event has ended, the duration of the Force Majeure
               Event, and shall resume performance of its obligations under this
               Agreement.

20.2   As soon as reasonably practicable and in any event within 48 hours
       following notification by CTI of a Force Majeure Event CTI shall develop
       and provide to BDB an outline plan of action for overcoming the Force
       Majeure Event and a timetable for implementation thereof for
       consideration by BDB. If such plan is acceptable to BDB, CTI shall
       proceed to implement such plan provided that BDB may terminate this
       Agreement by giving not less than 10 days written notice if such plan is
       not successfully implemented so as to end the Force Majeure Event within
       the timescales agreed. If the parties fail to agree an outline plan or
       CTI fails to meet the said agreed

                                       37

 
       timescales the parties shall, through the Change Control Procedure and
       subject to regulatory consents, attempt to agree to vary the Services and
       the Charges, and in default of such agreement within such timescales as
       BDB shall reasonably determine then BDB shall be entitled to terminate on
       30 days prior written notice.

21.    LIABILITY AND INSURANCE

21.1   Each party shall maintain appropriate insurance against any loss,
       damages, claims or actions arising out of the performance by it of its
       obligations under this Agreement from:

       21.1.1  personal injury or death;

       21.1.2  public liability; and/or

       21.1.3  any other liability for which either is required by law to
               insure.

21.2   Service Credits shall be payable by CTI in the manner calculated as set
       out in Schedule 7.

21.3   BDB's entitlement to Delay Rebate and Service Credits of all Stations in
       any twelve month period shall not exceed [*] in aggregate. For the
       avoidance of doubt, nothing in this Clause 21.3 shall prevent BDB from
       claiming damages in respect of any breach of this Agreement which might
       otherwise have given rise to an entitlement to a Delay Rebate or Service
       Credits.

21.4   CTI's total aggregate liability in respect of all claims made under or in
       connection with this Agreement (including Services Credits and Delay
       Rebates) arising out of any event or series of events in any Year will be
       limited to an aggregate amount equal to [*] as set out in Schedule 2
       Table 1, whether such liability arises in contract, tort, negligence,
       misrepresentation, breach of statutory duty or otherwise howsoever.

21.5   CTI shall not be liable to BDB for loss of profits or for any indirect,
       special, incidental or consequential loss whatsoever arising out of its
       performance of or failure to perform this Agreement, whether in contract,
       tort, negligence, misrepresentation, breach of statutory duty or
       otherwise howsoever.

21.6   Nothing in this Agreement shall exclude CTI's liability for death or
       personal injury caused by its negligence.

21.7   BDB shall not be liable to CTI for loss of profits or for any indirect,

       performance of or failure to perform this Agreement, whether in contract,
       tort, negligence, misrepresentation, breach of statutory duty or

       the revenue it would have earned from BDB under this Agreement but for a
       breach by BDB of this Agreement.

21.8   Nothing in this Agreement shall exclude BDB's liability for death or
       personal injury caused by its negligence.

22.    ASSIGNMENT AND SUB-CONTRACTING

22.1   This Agreement is personal to the parties hereto and neither may assign,
       transfer, charge or deal in any other manner with this Agreement other
       than as expressly set out below except that CTI shall be entitled to
       assign its rights to payments under this Agreement by way of security to
       any person providing finance to it or to any member of its Group subject
       to receiving BDB's prior written consent (such consent not to be
       unreasonably withheld).

22.2   Each of CTI and BDB shall be entitled to assign this Agreement to any
       wholly-owned subsidiary provided that:

       22.2.1  the transferor procures that the transferee is bound by a direct
               covenant with the other party to observe all the terms of this
               Agreement and the obligations of the transferor contained in this
               Agreement if the transferee were a party to this Agreement; and

       22.2.2  if any transferee ceases to be a wholly-owned subsidiary of the
               transferor, this Agreement will be transferred back to the
               transferor, or to a wholly-owned subsidiary of the transferor.

22.3   BDB may on notice to CTI assign this Agreement to any person holding a
       valid licence to provide multiplex services over the BDB Multiplexes
       providing that the proposed assignee enters into an legally binding
       covenant with CTI to be bound by and perform the obligations of BDB under
       this Agreement from the date of the assignment as if the assignee were
       party to this Agreement in place of BDB.

22.4   CTI may, with BDB's prior written consent, sub-contract any of its
       obligations under this Agreement (such consent not to be unreasonably
       withheld) providing that CTI procures that the sub-contractor complies
       with CTI's obligations under this Agreement as if it were a party to this
       Agreement in place of CTI. Nothing in this Clause 22.4 will relieve CTI
       of any of its liabilities or obligations under this Agreement.

23.    INFORMATION AND CONFIDENTIALITY

23.1   Each party agrees and undertakes that during the Term, and thereafter, it
       will keep confidential and will not use for any purposes other than as
       contemplated in this Agreement or, without the prior written consent of
       the other, disclose to any third party the terms of this Agreement or any
       information of a confidential nature which is supplied to it under this
       Agreement or of which it becomes aware in the performance of this
       Agreement unless:

                                       39

 
       23.1.1  such information is required to be disclosed to the respective
               financiers of CTI or BDB, to members of their respective Groups
               or their shareholders, subject in each case to such companies or
               individuals agreeing that the information shall be confidential
               in terms substantially similar to this Clause 23.1;

       23.1.2  such information is public knowledge, or subsequently becomes
               public knowledge, other than by breach of this Agreement;

       23.1.3  such information subsequently comes lawfully into the possession
               of the party in question from a third party; or

       23.1.4  the disclosure of such information is required pursuant to law,
               by any court of competent jurisdiction or any regulatory
               authority, including any recognised stock exchange or any
               taxation authority.

23.2   To the extent that it is necessary to disclose confidential information
       pursuant to the provisions of this Clause 23.2 or otherwise as is
       necessary to implement the provisions of this Agreement, either party may
       disclose any confidential information concerning this Agreement to its
       employees, agents, professional advisers or authorised sub-contractors on
       a "need-to-know basis"; provided that before any such disclosure such
       party shall make such persons aware of its obligations of confidentiality
       under this Agreement and shall at all times procure compliance by such
       persons with these obligations of confidentiality as if they were party
       to their Agreement.

23.3   CTI may not refer to this Agreement in any publicity or advertising
       material without first obtaining BDB's written consent.

      contains the whole agreement between the parties relating to the subject
      matter of this Agreement.

      Agreement shall not affect any other provision herein or render this
      Agreement invalid or unenforceable.

PART II -  ANNUAL RPI INCREASES

The Charges set out in Part I of this Schedule (the "UNADJUSTED CHARGES") are
shown before the effect of increases calculated in accordance with this Part II.

With effect from each anniversary of 1 January 1998 (the "REVIEW DATE") the
Unadjusted Charges shall be subject to RPI review and shall be increased by an
Adjustment Factor as set out below.

An "ADJUSTMENT FACTOR" is calculated for each calendar year starting with a
value of 1 on 1 January 1998. The Adjustment Factor for the year commencing at
each Review Date is calculated by increasing the Adjustment Factor for the
previous calendar year by the Adjusted Rate of Inflation (as defined below). The
Charges for the current calendar year are calculated by multiplying the figure
for the Unadjusted Charges in respect of that year set out in Part I of this
Schedule by the Adjustment Factor.

The "ADJUSTED RATE OF INFLATION" shall be calculated by [*] the Rate of
Inflation.

The "RATE OF INFLATION" shall be calculated as follows:

Rate of Inflation   =    A - B  x  100   (shown as a percentage amount)
                         -----
                           B
 
Where  A  =   RPI at 31 December, immediately prior to the Review Date
 
       B  =   RPI at 31 December, 12 months preceding the Review Date
 
All the above can be written as a formula:

Current year Charges  =  Unadjusted Charge set out in Part I of this Schedule x
                         Adjustment Factor

where:

Adjustment Factor     =

Adjustment Factor for previous calendar year  x  (1 + A - B  [*])
                                                      -----       
                                                        B

and

Adjustment Factor for the first calendar year of the Term = 1

                                      48

 
In the event that RPI is reset or no longer published, the above calculation
will be replaced with an equivalent formula which will result in the same
Adjusted Rate of Inflation as would have been achieved had the RPI remained
available or not been reset as the case may be.

If in recalculating the Charges prior to the 5/th/ Anniversary of 1 January 1998
the Rate of Inflation shall exceed [*], but shall not exceed [*], then [*] shall
be deemed to be the Rate of Inflation for the purposes of calculating the
Charges for the year in question. If in such recalculation of the Charges, the
Rate of Inflation shall exceed [*] then the parties shall renegotiate in good
faith and on an open book basis the [*] deemed Maximum Rate of Inflation to be
applied in calculating the relevant Charges.

PART IV - THE CONTINGENCY

The Charges have been calculated with the inclusion of an amount of [*] (the

The Contingency Amount is intended to be utilised by CTI in defraying unforeseen
or increased costs to the extent that such increased or unforeseen costs have
not be defrayed by CTI from savings pursuant to Clause 17.7. If by a date
falling three months after the last Station comes into Operational Service
(excluding any Additional Stations, unless otherwise agreed by the Parties)
there shall remain unutilised any balance of the Contingency Amount in respect
of any identified category of expenditure, the balance shall be utilised to

reduction in the Charges in a manner to be agreed between the parties failing

Term.


PART V - BASIS OF CHARGING [*]


PART VI - THE WTA LICENCE FEE

To the extent that any licence fees are payable by CTI in respect of any WTA
Licences relating solely to the operation of the BDB Multiplexes:

1.1  shall exceed [*] per annum per BDB Multiplex then the Charges in respect of
     the year in which the WTA Licence fee is payable shall be increased by an
     amount equal to that excess; or

1.2  fall short of [*] per annum in the first full year following the last
     Station coming into Operational Service (excluding any Additional Stations,
     unless otherwise agreed by the parties) or any subsequent year in which the
     WTA Licence fee is payable per BDB Multiplex then the Charges in respect of
     that year that shall be reduced by an amount equal to the shortfall.

                    SCHEDULE 3 CONFIGURATION OF THE NETWORK

PART I - DISTRIBUTION

Multiplex distribution provides resilient terrestrial circuits from the
Multiplex Centre to each of the 81 transmitting stations.

The circuits will be provided by BT on behalf of CTI, and will comprise
diversely routed dual fibre circuits carrying three multiplexes to BT network
access points. At these access points the BDB signals will be combined with
those from other DTT multiplex operators for onwards delivery via a common
network.

Interfaces will be provided at the Multiplex Centre to enable transport streams
with different programming to be fed independently to six "macro regions". This
facility will be provided for multiplexes B, C and D. The Stations within each
macro region will be as for Multiplex 2 unless otherwise agreed by the parties
through the Change Control Procedure.

NETWORK TECHNOLOGY & RESILIENCE

Terrestrial circuits will be designed to provide availabilities of 99.99%
through the use of optical fibre circuits. This diversity will be maintained
throughout the network, such that there are no common points of failure. At a
few of the very remote sites, where the provision of dual optical fibre paths is
not practicable, service may be provided on duplicated digital radio links,
engineered to the same level of availability.

The network will consist of circuits providing connectivity from the local BT
network nodes to the transmitter sites. These circuits will be provided
specifically for this purpose on dedicated optical fibres. To maintain
resilience upon the failure of a single incoming circuit, the line-termination
plant will be configured to provide 'cross protection', such that upon the
failure of one incoming circuit, the remaining diverse feed will feed both
halves of the core network or transmitter input equipment.

A core national network, providing interconnection between the BT nodes, will be
provided on existing BT digital line plant using SDH technology. The automatic
re-routing capabilities of BT's SDH network will ensure that full diversity is
restored automatically should any individual element of the core network fail.

TOPOLOGY

Although a common delivery network will be utilised, aggregation with other
broadcasters signals will be carried out at BT network nodes, and BDB's signals
will not be routed via any other broadcasters premises. The multiplexes, as
originated from the Multiplex Centre, will be delivered to each of the primary
sites listed below. Where any secondary Sites are shown these will be fed via
the primary Sites, from the output of the SI processing equipment.

The transmitter input system at the secondary sites will consist only of
duplicated COFDM modulators since the incoming transport stream will contain the
correct SI information from the associated primary station.

                                       53

 
NETWORK MONITORING AND MANAGEMENT

The service will be provided as a fully managed network and CTI will have on-
line access to the BT network management system providing details of the network
status. This will allow rapid fault diagnosis and escalation, together with
reporting to BDB as provided in Clause 14.

At the BDB Interface, BDB's multiplex streams will be tagged with a unique
identification header, which will remain with the stream until the final point
of delivery. This will enable the terminating equipment to ensure that the
correct BDB stream is being delivered to the transmitters at all times, and take
appropriate executive action in the case of any equipment faults or
configuration errors.

CTI will install new DTT auto-start, auto-changeover diesel generators at all
stations. These will be containerised where planning regulations allow and will
have sufficient fuel for a minimum of 24 hours full-power operation.

Duplicate power distribution will provide resilience for fault conditions or
maintenance activity.

                                       63

 
UPS units will be provided to protect individual key items of equipment within
the transmitter input system as appropriate.

                    SCHEDULE 3 CONFIGURATION OF THE NETWORK

PART  IIA - SI DATA INTERCHANGE

SYSTEM REQUIREMENTS

It is specified in the D Book that 'each multiplex must carry certain SI
information for certain other multiplexes', in particular Event Information
Table entries.

[*]

Where the regional SI permutation is appropriate to other Sites in the locality,
the modified transport streams will be delivered onwards to those Sites via the
Distribution Network.

SYSTEM OVERVIEW

[*]

All of the acquired SI, along with the SI relating to the BDB multiplex, will be
collated and reinserted into the outgoing transport stream.

The SI Collation System ("SICS") will be configured to ensure that appropriate
bit-rate will be apportioned to the 'Other multiplex' table data within the
stream in accordance with the recommendations of the D-Book ("GUARANTEED
BANDWIDTH"). The SICS will also ensure that the incoming 'Other multiplex' data
conforms to 'D' Book technical standards ("QUALIFYING DATA"), rejecting data as
necessary to ensure the integrity of the 'Actual' multiplex.

                    SCHEDULE 3 CONFIGURATION OF THE NETWORK

PART IIIA - NETWORK STATUS SYSTEM

A Network Status System will be provided to BDB to display the current status of
the Network.

A dedicated Kilostream circuit will be provided from the TOC to the BDB
Multiplex Centre. A personal computer and network equipment will also be
supplied as part of the Network Status System.

The following diagram outlines the proposed system:

[Diagram illustrating the configuration of the BDB network]

APPLICATION

An application, based upon a graphical user interface, will be supplied to
access the database and provide a graphical overview of the Network, as well as
showing more detail on individual Stations when required.

A dedicated database will be provided to hold a subset of the alarm and current
status of all the DTT transmitting stations. This status database will be kept
to within thirty seconds of the status that is known at the TOC system. The
database will also hold service messages for at least the preceding 18 months.
These can be used for ad-hoc queries and service level confirmation.

SERVICE LEVEL

The data circuit, database and graphical user interface application will form
part of the Service and will be the responsibility of CTI. The monitoring of
this circuit and PC will be incorporated into the TOC system and a watchdog
system will be used to ensure that any loss of the monitoring facility is
detected.

Throughout the life of the system CTI will make all reasonable endeavours to
ensure compatibility with current industry-standard operating systems.

SECURITY

CTI will provide suitable systems to protect the networks of both organisations.
This will include electronic firewalls on the telecommunications links and virus
checking on the BDB Network Status system computer.

BDB will need to maintain the physical security for the system to protect it
against local attack.

FUNCTIONAL DESIGN

A detailed functional design specification for the Network Status System will
ensure that any reasonable requirements of BDB are met within the constraints of
the CTI TOC system.

                           SERVICES PROVIDED BY CTI

GENERAL

QUALITY

CTI's operation is governed by a quality management system that is accredited to
ISO 9001.

As far as possible, CTI expects suppliers to operate under similar quality
arrangements.

CTI staff are chosen with appropriate skills and are kept up to date with
training, as needed, in new techniques and systems.

SAFETY

CTI's internal Safety Policy (the "Safety Policy") fulfils the company's legal
requirement under the Health and Safety at Work Act 1974.

The Safety Policy is carried out through a series of Company Safety Instructions
under the auspices of a full-time Company Safety Adviser (CSA).

All staff receive relevant training to carry out their jobs in accordance with
the Safety Policy. Such training is under continual review.

PART I - DESIGN AND PROCUREMENT

PROJECT MANAGEMENT

The following personnel am responsible for provision of the Network:

     Principal Account Manager:

     .    acts as primary point of contact between BDB and CTI for both Project
          and Service delivery issues.

     Project Manager:

     .    responsible for provision of Network infrastructure; and
     .    co-ordinates inter-site and on-site activities of project
          contributors.

     Technical Manager:

     .    ensures technical compatibility of Network elements; and
     .    ensures, compatibility of the Service with customer and industry
          expectations.

                                       71

 
Project schedules will be created and maintained under review for each site an
which there is project work in progress. From these a 'super-project' plan will
be maintained to co-ordinate intrasite activities.

The Project Manager will have direct access to all the relevant Resource Heads
to ensure provision of relevant resources.

Project meetings and systems architecture meetings will be hold regularly to
ensure cross-specialism, co-ordination and compatibility.

PROGRESS REPORTING

CTI will present a two weekly progress report to BDB. This report to will be in
the form of a project schedule. This will be in a software format compatible
with the project planning system used by BDB.

There will in addition be a brief narrative highlighting the main issues
associated with particular activities or sites.

RISK

CTI's risk management principles are encompassed in CTI's quality procedures.
The discipline is based on risk identification, analysis, mitigation and
management as an iterative process. This process will be managed by the Project
Manager and the Technical Manager.

PART II - OPERATIONS

SERVICE DELIVERY

Delivery of the service will be the responsibility of the Head of Operations,
who is:

     .    responsible for provision of an effective operations and maintenance
          system nation wide; and
     .    responsible for ensuring service level provision compliant with
          relevant contractual requirements.

TECHNICAL OPERATIONS CENTRE (TOC)

CTI has in place a TOC and this is the hub of CTI's network operations,
monitoring and management capability. It offers a full 24 hour, 365 day facility
staffed by specialist technical, managerial and operational staff. The TOC back-
up site at Sutton Coldfield provides technical resilience and geographical
separation.

Provision of a 24-hr TOC operation is the responsibility of the TOC Manager, who
ensures that TOC procedures are commensurate with service level provision.

The TOC will be equipped with the following systems:

                                       72

 
 .    a supervisory control and dam acquisition system (SCADA);

 .    a management information system (MIS) and wide area private data network;

 .    a wide area networked maintenance personnel despatch system;

 .    a Network Status System; and

 .    a standby power supply system with diesel generator and UPS.

The transmitting stations will operate unattended with remote monitoring fully
integrated into the TOC. The TOC will initiate operational response to potential
and service-affecting faults in accordance with the provisions of Schedule 9 and
the Contracted Availability. The required operational support will be supplied
from one of a number of team bases which are located at various points
throughout the UK.

Alarm from the DTT monitoring equipment will arrive in the TOC and priorities
will be automatically assigned. In addition suspected problems may be reported
to the TOC from other sources. All such occurrences will be recorded and dealt
with accordingly via a pre-defined escalation procedure.

The TOC will provide operational information and statistics to meet the
performance monitoring and reporting requirements set out in Clause 14.

REMOTE CONTROL

The Duty Engineer or nominated deputy Engineer will be the only persons in the
TOC authorised to Initiate any control action.

CTI TEAM BASE MONITORING

All team bases will be equipped with receive systems for DTT. They will be able
to check (on an ad-hoc basis), the output from those stations which are
receivable at that base.

TV DEALER MONITORING

The TOC has an existing network of TV dealer contacts that are used to confirm
TV and radio reception and this facility will be extended for DTT reception
where practicable.

VIEWER MONITORING

At least one nominated audience contact for each DTT station will have direct
telephone access to the TOC to enable reporting of suspected problems and to
allow the TOC to contact them to confirm problems reported from another source.

PART III - MAINTENANCE

FAULT REPAIR AND RECORDING

                                       73

 
The first priority of maintenance staff will be to ensure that the service is
restored. The next priority will be to restore system redundancy by repairing
reserve or standby equipment. Fault rectification will usually be by replacement
of faulty units or modules.

Fault repair down to component level will usually be done at Daventry (see
below).

A database of fault history will be maintained to identify any trends with a
view to improving system reliability.

ROUTINE MAINTENANCE

Any necessary routine maintenance will be carried out by maintenance staff on an
"as necessary" basis. The frequency of such work will be determined by condition
monitoring and analysis of the database of fault history.

Routine maintenance will be planned in such a way that the outgoing service is
unaffected by the activity. Any work which is service-affecting will be carried
out under the Planned Work regime (below).

PLANNED WORK

The number of DTT channels sharing antenna systems will make planned outages and
switching breaks more difficult to negotiate in future. Antennas shared between
analogue and digital services present even greater difficulty.

CTI are committed to the formulation of an agreed CTI/NTL rolling 12 month
planned work programme for structural maintenance. To that end a formalised
negotiation method is proposed within the following guidelines:

 .    ensure that a clear need for the work to be done can be shown;

 .    parallel negotiations between identified points of contact within each
     organisation to minimise the time taken to reach agreement;

 .    a rotating 'veto' system, ensuring fair and equitable treatment of all
     requests:

 .    agree with each operator those programme periods that they regard as
     highest priority; and

 .    equalisation of the effects of planned work on all services at a
     particular station.

DAVENTRY CENTRAL MAINTENANCE FACILITIES

CTI has a central maintenance and supply facility at Daventry which operates on
the following principles:-

 .    repair of equipment down to component level.

 .    work is done under controlled conditions by experienced staff; and

                                       74

 
 .    a central store of spare units and parts is maintained to support field
     requirements.

It provides additional support including a fast turn-around modular repair
service, parts purchasing, a spares control/delivery system and a test equipment
calibration service.

SPECIALIST SUPPORT

The existing callout procedure will be expanded to include out of hours support
for maintenance teams.

An escalation procedure will ensure that an appropriate level of support is
available for all incidents. This will be implemented via the TOC which will
maintain a schedule of engineers who have specialised knowledge of nominated
systems and equipment used in the Network. These engineers will come from CTI's
Operations and Engineering departments as well as external organisations
contracted to provide support where necessary. The escalation procedure will
include CTI's senior management who will ensure that appropriate resources are
deployed rapidly to resolve any relevant problem.

PART IV - CUSTOMER SUPPORT

SERVICE PLANNING SUPPORT

CTI will provide support to BDB as follows:

 .    liaison with NTL and BBC R&D as necessary;

 .    consultation with the ITC and RA as appropriate; and

 .    advice on subscriber coverage issues. (This will include a telephone
     hotline which will operate 09:30 to 17.30 Monday to Friday, with backup
     from the TOC at other times. The TOC will call on specialist engineering
     support to deal with urgent enquiries when necessary, on an ad-hoc basis.)

CTI will deploy additional resources from its partner TDF as necessary.

CTI will survey DTT coverage by actual measurement of field strength at early
installations, concentrating on areas where coverage is predicted to be
marginal. The CTI prediction models will then be refined iteratively using
measured data to a level where further verification is deemed unnecessary by
both parties. Predictions will take due account of the degree of interference to
be expected as the network expands.

CTI will verify that now DTT transmit antennas as installed will comply with the
relevant Template.

                                       75

 
This shall be achieved by electrical and mechanical tests and inspections of the
antenna, on works acceptance and as a part of installation commissioning. This
work will conform with current best industry practice.

CTI will make the results of these tests available to BDB. BDB reserves the
right to carry out independent tests to verify compliance with the relevant
Template.

In order to be able to verify that field strength remains stable over time, a
series of reference measurements will be made at agreed locations.

CTI will make additional support available for service coverage measurements
when requested by BDB in accordance with the rate card arrangements in Clause
9.5.

TEST TRANSMISSIONS AT EARLY STATIONS

Prior to the launch of service CTI shall provide early test transmissions to an
agreed timetable at an agreed (small) number of Stations. The purpose of these
transmissions is to provide early verification of planning tools and assumptions
and to provide a source of signals for receiver testing. The format and content
of these transmissions is to be agreed between CTI and BDB.

Routine Test Transmissions will be provided at all Stations as part of the
commissioning and acceptance process.

                                       76

 
SOURCE EQUIPMENT

Prior to the availability of Distribution Network feeds at the test Stations,
CTI will provide temporary source equipment as necessary to ensure that Test
Transmissions can take place. CTI have included costs for up to [*] for the
provision of the necessary source equipment. Purchase of additional equipment
will be dealt with under the Change Control Procedure. The format of this
equipment and the storage medium used will be agreed between CTI and BDB. Any
programme material required for Test Transmissions will be provided by BDB in an
agreed format.

As the Distribution Network becomes available the Test Transmission signals will
be inserted by CTI at the BDB Interface using equipment similar to that provided
at the Stations. At an agreed time, prior to the first start of Site Service
Date, BDB shall make signals suitable for transmission available at  the BDB
Interface.

TEST BED

CTI will continue to support the development of DTT systems using testbed
facilities at Sutton Coldfield to test new equipment and systems.

                  THE BDB INTERFACE AND HANDOVER REQUIREMENTS


PART I - DISTRIBUTION

ACCOMMODATION

CTI will require secure accommodation within the Multiplex Center for the
installation of the circuit terminating equipment, and any associated monitoring
(the "CTI Area").  Provision is required for two PTO racks (separate A&B
systems) and one CTI rack.  BDB shall be responsible for maintaining the ambient
temperature within this CTI Area between +10 degrees celsius and +30 degrees
celsius, by appropriate means.  The area shall be sufficient to provide front
and rear access to the PTO racks for maintenance and be adequately illuminated
to allow repair of electronic equipment in the racks.

POWER REQUIREMENTS

Each of the racks will consume up to 500w from a 230vAC supply provided by BDB.
In order to ensure full redundancy, the power for the "A & B" racks shall be
provided from diversely derived supplies, such that a single failure in the
power distribution system will not cause both supplies to fail simultaneously.
Should BDB choose to protect the supplies to the multiplex equipment with
locally generated or UPS supplies, then this level of protection shall also be
provided to the CTI interface area.  A suitable technical earth is also
required.

In addition to the equipment supplies, a minimum of four 'general purpose' 13A
sockets shall be provided adjacent to the racks for the connection of test
equipment.

TELECOMMUNICATIONS REQUIREMENTS

The distribution circuits from the CTI Area require diverse optical fibre
routing to the PTO network with an agreed practicable separation within the
building until they approach the CTI Area, thereafter a reduced practicable
separation shall be provided.  Either a PSTN Direct Exchange Line or an
extension of the BDB multiplex centre telephone system will be required within
the CTI area.

ACCESS ARRANGEMENTS

CTI& BDB shall agree on a system such that necessary maintenance personnel can
gain access to the CTI Area for the diagnosis and correction of equipment
faults, on the production of an appropriate identification.  Access is required
on a 24hr/365 day basis, and includes PTO staff unaccompanied by CTI for the
correction of circuit faults but will be subject to an agreed operational
procedure.

                                       92

 
TRANSPORT STREAM PRESENTATION

Each of the three groups of six macro region transport steam multiplexes shall
be a single presentation in an agreed ASZI format.

Due to availability and reliability considerations, CTI do not propose to re-
generate the transport stream prior to connection to the terrestrial circuit
interface.

Each transport stream provided at the interface point will be at an agreed
bitrate.

                                       93

 
PART II - NETWORK STATUS SYSTEM

For a detailed description of the Network Status System please refer to Schedule

                                  SCHEDULE 7

               CALCULATION OF DELAY REBATES AND SERVICE CREDITS


PART I - ILLUSTRATION OF RELATIONSHIP BETWEEN DATES

The following diagram illustrates the relationship between the types of the date
specified in the Contract.



   [Diagram which illustrates the relationship between the types of the date
specified in the Contract]


Contractual Review of Dates             See Clause 4.3.

Ready for Test Transmission date:       DTT Station ready to transmit and
                                        associated analogue transmitter work
                                        complete at all relevant Stations.

Ready for Service date:                 As defined in the Agreement

Start of Service date:                  As defined in the Agreement


PART II - CALCULATION OF DELAY REBATE

Table 2 lists the Daily Charges which apply under the circumstances specified in
Clause 6.

In order to calculate the Delay Rebate, the numbers of days from the relevant
Ready for Service Date to the Actual Site Service Date Inclusive ("Days of
Delay") shall be calculated in accordance with Clause 6 and entered into Table
3.  The Delay Rebate for each Station shall be entered on the table by
multiplying the Days of Delay and the Daily Charge.

                                       95

 
In the case of one BDB Multiplex being delayed, the Delay Rebate shall be the
same as if all BDB Multiplexes have been delayed at that site.

Table 3 shall be completed each Year for all Station which reach their Actual
Site Service Date in that Year.  The Total Delay Rebate for that year (the sum
of the column, shown on the last line of Table 3), shall be subtracted from
CTI's first monthly invoice in the following year.

PART III - CALCULATION OF SERVICE CREDITS

Service Credits become payable if Accountable Availability falls below [*],
except in the case of Bressay, Eitshal, Keelylang, Hill and Torosay where
Service Credits become payable if Accountable Availability falls below [*].

DERIVATION OF ACCOUNTABLE AVAILABILITY

               Accountable Availability = A-B x 100%
                                          ---       
                                           A

Where:

A = Total number of minutes in the previous six months

B = Total number of minutes in the previous six months during which performance
is worse than the Service Shutdown Threshold as defined in Schedule 5 Part II,
arising other than as a result of Non-Accountable Conditions.  This is defined
as Minutes Lost.

For each of the first five months after Start of Service, Accountable
Availability shall be calculated over the previous six months by treating
performance prior to Start of Service as always exceeding the Service Shutdown
Threshold i.e. the contribution to variable B in the above equation for those
months shall equal zero.

The following are Non-Accountable Conditions:

a)   a Force Majeure Event;

b)   extreme weather conditions affecting traveling to any remotely located
     Station;

c)   a delay of no more than [*] in re-establishing the Services when
     switching to standby equipment;

d)   a delay of no more than [*] in re-establishing the Services when
     switching to alternative power supplies;

e)   interruption for essential or planned works on mast structures, GRP
     cylinders and stays made in compliance with Clauses 15.1 or 15.2. The
     timing and length of each interruption shall be agreed by the parties as
     set out in Schedule 4 Part III;

[*]  indicates where text has been omitted pursuant to a request for
     confidential treatment. The omitted text has been filed with the Securities
     and Exchange Commission separately.

                                      96


 
f)   frequency planning or international frequency clearance issues;

g)   incidents arising as a result of known and previously agreed fundamental
     equipment design deficiencies which cannot be immediately rectified, from
     the date at which the deficiency is identified and agreed by the parties,
     to the date agreed for rectification;

h)   compliance with the mandatory requirements of any law, any national or
     supranational regulatory authority, the Radio Regulations or any statutory
     obligations;

i)   planned and previously agreed interruptions to undertake modifications to
     the DTT Transmission Network required by BDB and/or legal or regulatory
     bodies such as the Radio-communications Agency and the Independent
     Television Commission, unless the interruption is required to remedy a
     situation arising due to the fault or omission of CTI, its agents or sub-
     contractors;

j)   where invasive tests are required by BDB, such as the measurements of group
     delay, provided that the results meet the Technical Specifications.

k)   any failure or degradation of the signal or message comprising the BDB
     Signals from the BDB Interface to the CTI interface;

l)   any material breach of this Agreement by BDB (or any act or omission of it
     or its agents or sub-contractors) to the extent that it prevents or impedes
     the performance of CTI's obligations to provide the Distribution Service
     and DTT Transmission Service; and

m)   where any of the relevant part of the Network is requisitioned, taken over
     or used pursuant to the exercise of any Emergency Powers.

Account Availability shall be calculated at the end of each month, for each BDB
Multiplex at each of the sites listed in Table 3.  The result shall be sent to
BDB by the 7th day of the following month.

NON-COMPLAINT SERVICE

Each BDB Multiplex at each site which has an Accountable Availability result of
less than [*], shall be deemed a Non-Complaint Service ([*])

At the end of each month, a Service Credit amount shall be calculated for each
Non-Complaint Service.

The value of the Service Credit shall be related to the severity of the service
loss, by taking account of the time of day when the performance was worse than
the Service Shutdown Threshold, and the population served by the Non-Complaint
Service.  This shall be achieved through the use of adjustment and weighting
factors in Tables 1, 2 and 3.

[*] indicates where text has been omitted pursuant to a request for confidential
    treatment. The omitted text has been filed with the Securities and Exchange
    Commission separately.

                                      97

 
CALCULATION OF SERVICE CREDITS

Each month, the total Minutes Lost by a Non-Complaint Service during the
previous six months shall be entered into the second column of Table 1, with
separate figures for losses during each hour of the day. Each figure shall then
be multiplied by the corresponding Time Adjustment Factor to give Unweighted
Service Credits, which are totalled to give the Unweighted Service Credit Total,
The Service Credit shall be calculated by inserting the relevant Station
Weighting Factor from Table 3 and multiplying it by the Unweighted Service
Credit Total.

                                       98

 
Format of Table 1

The figures in italics are for illustration and they are included in order to
demonstrate that 60 minutes complete loss of service from one multiplex at
Crystal Palace during peak time will result in a Service Credit payment of [*].
This total will accrue because the 60 minute loss of service will be included on
the table below for six consecutive months, giving six payments of
[*].

The table shows a 60 minutes loss of service between 21:00 and 22:00.  The time
lost, in minutes, is entered in the second column and multiplied by the Time
Adjustment Factor in the third column (100 in this case) to achieve a monetary
Unweighted Service Credit as shown.  The Unweighted Service Credits are totalled
down the column (S) and multiplied by the Station Weighting Factor to obtain a
Service credit of [*].

SERVICE CREDITS FOR SIMULTANEOUS FAILURE AT MORE THAN ONE STATION

If a single distribution failure results in more than one Station having a Non-
Complaint Service, then Service Credits with respects to this simultaneous
failure at more than one Station shall be calculated as follows, instead of
using Station Weighting Factors from Table 3:-

   Unweighted Service Credits shall be calculated using Table 1 and then the
   Unweighted Service Credit Total shall be multiplied by the relevant Service
   Weighting Factor given in Table 2, to derive the Service Credit.

               SCHEDULE 7 - TABLE 2 - Service Weighting Factors

                                      [*]

   For the purposes of this Table only the population served shall be the gross
   population figures for the relevant multiplexes at the relevant Stations, as
   defined by the ITC from time to time.

TIMING OF SERVICE CREDIT PAYMENTS

A Service Credit payment shall be made one per Year only and it shall be in the
form of a reduction in CTI's first monthly invoice for the Year.  The amount of
the reduction shall equal the total of Service Credits calculated during the
previous Year.

[*] indicates where text has been omitted pursuant to a request for confidential

                                      100

 
REDUCTION DURING THE INITIAL PERIOD

During the first three months after Start of Service, each Minute Lost will be
reduced by 50% before entering the resultant figures into Table 1.  This
reduction is subject to one month "burn in" period being available prior to
Start of Service date.  Should this period not be available then the reduction
is decreased in proportion e.g. two weeks "burn in" equates to six weeks
reduction.

                                  SCHEDULE 9

                              THE IMPACT SCHEDULE
                       (BDB DTT ANALOGUE CONSEQUENTIALS)

PART I - INTRODUCTION

This document defines the work which CTI will undertake, either directly or
through NTL, in connection with the modifications to existing analogue TV plant
as a result of the introduction of the DTT service in the UK.

The work described here is strictly limited to the consequentials of the
introduction of the BDB Multiplexes.

The work described forms the 'baseline' for CTI's responsibilities under the BDB
DTT Contract. It reflects the changes which are known at 15 August 1997. Any
further changes will be dealt with under the 'Change Control' procedures as laid
down in Schedule 1 of the DTT Contract.

PART II - SCOPE OF WORK

The work described in this Schedule and included in the Contract price is
outlined in the following ITC documents:

 .    "Impact of Digital TV Relay Stations on UK Analogue Services", Doc. No. 18,
     Ver 1.0, 30 April 1997;

 .    "Impact of Digital TV Main Stations on UK Analogue Services, Results of
     field work for Stage 1 and 2 sites", Doc. No. 19, Ver 1.0, 31 May 1997; and

 .    "Change to DTT Frequency Plan", Doc. No. 21, Ver 1.0, 6 August 1997.

PART III - SPECIFIC EXCLUSIONS IN THIS SCHEDULE

Please refer to the list of specific exclusions in Schedule 9, Table I and Table
2.

In particular, the following are not included:-

 .    domestic re-tuning; and

 .    any subsequent changes required by the ITC.

PART IV - SCHEDULE OF WORK

DESCRIPTION OF WORK AT SITES OTHER THAN DTT STATIONS

Schedule 9, Table 1 shows the type of work required at each of the analogue
relay stations in connection with the introduction of the BDB Multiplexes. The
work under the various headings is described below:

                                      109

 
PRECISION OFFSET

In most cases precision offset is impossible to implement with the existing
equipment due to its design. At such sites the transmission plant will have to
be replaced.

CHANNEL CHANGE

Existing equipment can generally be retuned. However the ITC stipulates that
there is to be no degradation of service for existing viewers. This means that
the old and new channels should be simulcast for a period to be specified by the
broadcasters which will require the purchase of temporary systems.

In addition the broadcasters require the use of captioning on the existing
channels in such circumstances.

INCREASE IN ERP

This can be achieved either by the modification of the transmit antenna or by
increasing the transmitter output power. In most cases this is combined with
precision offset working so new equipment Is called for. In cases where space is
limited and the transmission plant is integrated into one bay, an increase in
ERP of one service will mean that new equipment will be required for all the
services on a site.

NEW ANALOGUE RELAY

In five cases new relays will be provided. At [*] this will be by addition of
equipment at an existing NTL site where space exists in the current building
([*] will be fed by RBL from Wrexham-Rhos).

At Prestatyn a new Relay will have to be built on a green-field site.

RBL ANTENNA MODIFICATIONS

In a few cases modification of the existing site RBL receive antennas is
required to reduce Interference to the received signal.

NEW TRANSMIT ANTENNA

In some cases, a new transmit antenna is required for one or both of the
following reasons:-

 .    to increase the ERP of the station with an antenna of greater gain; and/or

 .    to suit the new channel allocation(s).

DESCRIPTION OF WORK AT CO-SITED STATIONS

Schedule 9, Table 2 shows the work required to modify the existing analogue
transmission system, at stations, with co-sited DTT services, as a result of the
introduction of the BDB Multiplexes. The work under the various headings is
described below:-


     MODIFICATION OF VESTIGIAL SIDEBAND REGION

     To avoid degradation of a DTT multiplex which is lower adjacent to an
     existing analogue service, the VSB region of the analogue service must be
     modified. This will be carried out both at low power in the analogue drive
     equipment and also with high power filtering at the output of the
     amplifiers. This work is subject to approval by the relevant regulatory
     authority.

     MODIFICATION OF GROUP DELAY

     As a consequence of the high power filtering required to restrict the VSB
     region extra group delay correction will be required on all analogue
     services with lower adjacent DTT multiplexes. This correction will be
     installed within the analogue drive equipment. At sites where the DTT
     services are to be combined with the analogue services and transmitted from
     a common antenna this extra correction must be configured such that it can
     be easily removed from circuit when maintenance is carried out on the
     analogue equipment. Extra group delay correction will also be required at
     sites where the DTT multiplex is upper adjacent to the analogue service,
     this is easier to accomplish than at lower adjacent sites.

     PRECISION OFFSET

     Precision offset oscillators will be installed in the analogue equipment at
     five co-sited stations. This is necessary to avoid co-channel interference
     with analogue relay stations which must be frequency changed as a
     requirement of the ITC frequency plan.

     REPLACEMENT DRIVES

     A total of four analogue services will require replacement drive equipment.
     The type of drive equipment presently employed at these sites cannot be
     modified to allow lower adjacent DTT operation. New drive equipment will be
     procured and interfaced to the existing control circuits and high power
     amplifiers.

    treatment. The omitted text has been filed with the Securities and Exchange
    Commission separately.

                       SCHEDULE 11 -EMERGENCY EQUIPMENT
                         /DISASTER RECOVERY PROCEDURES

PART I - EMERGENCY RESERVE EQUIPMENT

BDB Exclusive Equipment:

 .  3 off 4kW containerised DTT transmitters including TIE; and

 .  3 off 1kW containerised DTT transmitters including TIE.

Interconnection cabling and instructions will be maintained in portable cases in
accordance with an agreed operational procedure.

CTI EXCLUSIVE EQUIPMENT:

 .  1 off modular DTT combining system with interconnecting feeder; and

 .  2 off Broadband 8 Lambda 4 panel UHF Antennas.

CTI/NTL SHARED EQUIPMENT:

Some of these facilities are shared with NTL. Items are fully maintained under
an annual maintenance plan and include:

 .  210m reserve mast;

 .  80m reserve tower;

 .  16 lambda main UHF antenna,

 .  4 lambda UHF antenna;

 .  5 inch feeder;

 .  3 inch feeder;

 .  UHF combiner: and

 .  documentation.

Adaptors and feeders for interconnecting points will be available at all sites.

Emergency facilities will be phased in appropriately as installations progress.

                                      117

 
PART II- DISASTER RECOVERY PROCEDURES

In the event of a serious incident CTI will follow the procedures laid down in
the CTI Disasters and Emergencies Procedures Plan which is updated when
necessary and covers the following:

 .   security procedures;

 .   electric shock;

 .   loss of transmission facilities;
    mast collapse;
    loss of transmitters,
    emergency link procedure;
    local site plans;
    procedural testing;

 .   other emergencies;
    mast rescue;
    Falling Ice;
    bomb precautions; and

 .   a telephone list.

NOTIFICATION

In the event that a potentially catastrophic incident is detected, which will
impair or interrupt service from one or more Stations for an extended period,
CTI shall immediately notify the BDB Representative and initiate the CTI
Disasters and Emergencies Plan.

CTI and the BDB Representative will then jointly assess the implications of the
incident.

SERVICE PRIORITY

In the event of failure of more than one service at a Station, the order of
priority for service restoration will be in accordance with the CTI Disaster and
Emergencies Procedures Plan.

CTI will use reasonable endeavours not to show undue preference to any other
customer in the order of priority set out in the CTI Disaster and Emergency
Procedures Plan.

LOSS OF MAINS SUPPLY AND GENERATOR

In the event of fire destroying a mains supply and the backup generator
simultaneously, a containerised generator will be supplied within 24 hours on
hire.

                                      118

 
LOSS OF COMPLETE TRANSMITTING STATION

In the event of the loss of a complete transmitting station, CTI will deploy the
containerised emergency transmitters and other equipment necessary to restore
the service.

An emergency container transmitter can be delivered to any site on the mainland
within 24 hours.

MAJOR DAMAGE TO MAST AND/OR ANTENNA SYSTEM

Following notification or identification of potential structural damage and an
initial assessment of potential safety hazards, named personnel will be
contacted to enable contingency plans to be initiated. These people are directly
responsible for the provision of the reserve facilities. Some of these
facilities are shared with NTL.

Service recovery times depend on the severity of damage. It is likely that the
erection time for the 210m mast would be four to five weeks. It could be
possible under favourable conditions to reduce this to about three weeks.

At smaller sites full service would be restored using cherry-pickers and cranes.

TECHNICAL OPERATIONS CENTRE (TOC)

The TOC has been designed to be fully resilient. A back-up to the TOC is located
at Sutton Coldfield providing duplication of the computer systems at the TOC.
Data communications from the Stations to these computer systems is via ISDN or
PSTN backup circuits which are instigated automatically without manual
intervention.

In the event that the TOC needs to be abandoned, staff would transfer to the
backup centre and the operation would be resumed within in one hour with no loss
of monitoring data. The transfer time will be minimised by providing remote or
mobile access to the backup centre.

Procedures specified in Schedule 1. The basis for calculating the additional
Charge for each additional station shall be the sum of:

[*]

The provision of additional Stations from 1 January 2002 will be subject to
separate agreement between BDB and CTI.

Once the additional charge is calculated and agreed, Schedule 2 will be adjusted
accordingly.

22.  SANCTIONS FOR BREACHES OF CONDITION

(1)  (a)  If the Commission is satisfied that the Licensee has failed to comply
          with any Condition of the Licence or with any direction given by the
          Commission under the Licence and it has given him a reasonable
          opportunity of making representations to it about the matters
          complained of, it may serve on the Licence a notice requiring him to
          pay to the Commission, within a specified period, a specified
          financial penalty.

     (b)  The amount of any financial penalty imposed pursuant to Condition
          22(1)(a) shall not exceed whichever is the greater of (Pounds)50,000
          (or such other sum as the Secretary of State may by order specify
          under Section 36 of the 1996 Act) or the amount determined under
          Condition 22(1)(c).

     (c)  The amount referred to in Condition 22(1)(b) is:

          (i)  three per cent of the share of multiplex revenue attributable to
               the Licensee for his last complete accounting period (as
               determined in accordance with Section 15 of the 1996 Act) in a
               case where a penalty under Section 17 of the 1996 Act has not
               previously been imposed on the Licensee during any period for
               which the Licence has been in force (the "relevant period"); and

          (ii) in any other case five per cent or the share of multiplex revenue
               attributable to the Licensee for his last complete accounting
               period (as determined in accordance with Section 15 of the 1996
               Act).

     (d)  Where any such penalty is imposed when the Licensee's first complete
          accounting period falling within the relevant period has not yet
          ended, the amount referred to in Condition 22(1)(c) shall not exceed
          three, or (as the case may be) five, per cent or the amount which the
          Commission estimates to be the share of multiplex revenue attributable
          to the License for that accounting period (as determined in accordance
          with Section 15 of the 1996 Act).

(2)  (a)  If the Commission is satisfied that the Licensee has failed to comply
          with any Condition of this Licence or with any direction given to him
          hereunder and it has given him a reasonable opportunity of making
          representations to it about the matters complained of, it may serve on
          the Licensee a notice reducing the Licence Period by a specified
          period not exceeding two years.

     (b)  Where the Licence is due to expire on a particular date by virtue of a
          notice served on the Licensee under Condition 22(2)(a), the Commission
          may, on the application of the Licensee by a further notice served on
          him at any time before that date, revoke that notice if it is
          satisfied that such revocation is justified by virtue of the conduct
          of the Licensee in relation to the operations of the Licensed Service
          since the date of the earlier notice. 

 
                                       22

23.  REVOCATION

(1)  (a)  If the Commission is satisfied that the Licensee is failing to comply
          with any Condition of the Licence or with any direction given by the
          Commission such that, if that failure were not remedied, it would
          justify the revocation of the Licence, the Commission shall serve on
          the Licensee a notice.

          (i)    stating that the Commission is so satisfied.

          (ii)   specifying the respects in which, in the opinion of the
                 Commission, the Licensee is failing to comply with any such
                 Condition or direction; and

          (iii)  stating that, unless the Licensee takes, within such period as
                 is specified in the notice, such steps to remedy the failure as
                 are so specified, the Commission will revoke the Licence.

     (b)  If at the end of the period specified in any notice under Condition
          23(1)(a) the Commission is satisfied that the Licensee has failed to
          take the steps specified in the notice and that it is necessary in the
          public interest to revoke the Licence, the Commission shall serve on
          the License a notice revoking the Licence.

(2)  The Commission shall revoke the Licence by notice in writing served on the
     Licensee and taking effect as from the time of service in

     (a)  the Licensee indicates to the Commission before the Commencement Date
          that he does not intend to provide the Licensed Service; or

     (b)  the Commission for any other reason has reasonable grounds for
          believing that the Licensee will not provide the Licensed Service
          after the Commencement Date and it has served on the Licensee a notice
          stating its grounds for believing that he will not provide that
          service after that date.

(3)  The Commission may revoke the Licence by notice served on the Licensee and
     taking effect either forthwith or on a date specified in the notice, in any
     of the following circumstances:

     (a)  if the Licensee ceases to provide the Licensed Service before the end
          of the Licence Period and the Commission are satisfied that it is
          appropriate to revoke the Licence;

     (b)  if the Licensee agrees in writing with the Commission that the Licence
          should be revoked;

     (c)  if the Licensee becomes a disqualified person in relation to the
          Licence by virtue of Part II of Schedule 2 to the 1990 Act or
          otherwise fails to comply with any requirement imposed on or in
          relation to the holders of multiplex licences by or under that
          Schedule:

 
                                       23

     (d)  if the Commission is satisfied that the Licensee:

          (i)  in purporting to comply with any of the Conditions of the Licence
               has provided information which is false in a material particular
               or has withheld any material information with the intention of
               causing the Commission to be misled; or

          (ii) in connection with his application for the Licence, provided the
               Commission with information which was false in a material
               particular or withheld any material information with the
               intention of causing the Commission to be misled;

     (e)  if, where the Licensee is a body, a change affecting the nature or
          characteristics of the Licensee or any change in the persons having
          control over or interests in the Licensee, or any other change giving
          rise to a failure to comply with any requirement imposed by or under
          Section 2 to the 1990 Act takes place (whether before or after the
          Commencement Date), which change is such that, if it fell to the
          Commission to determine whether to award the Licence to the Licensee
          in the new circumstances of the case, it would be induced by the
          change to refrain form awarding the Licence to the Licensee;

     (f)  without prejudice to the generality of Condition 23(3)(e), if, without
