BT EQUIPMENT AND SITE REQUIREMENTS, AND CUSTOMER'S CONTENT SIGNALS RESPONSIBILITIES 4.1 In order to be able to provide the Service, BT requires the Customer (at its own expense) to seek to arrange for the following at the Sites (up to the respective boundaries of the Sites): 12 (a) obtain and maintain all necessary landlords' consents, planning permissions, way-leaves and other third party consents (including those of Playout Centre Owners, and Transmitter Site Owners) needed to install, commission, maintain, operate and use the BT Equipment at the Sites and connect and operate the Service at the Sites, including consents for any necessary alterations to buildings; (b) pay all necessary connection charges, site rents, or any other fees required or levies made by third parties (including landlords, Playout Centre Owners, and Transmitter Site Owners) in connection with operating the Service at the Sites; (c) provide a suitable environment, accommodation, foundations, power supplies, connection points, support and other facilities at the Sites, including all necessary trunking, conduits and cable trays, as detailed in section 11 of the Functional Design Specification in accordance with the relevant installation standards; (d) take up or remove, any fitted or fixed floor coverings, ceiling tiles, suspended ceiling and partition covers, as BT advises are reasonably necessary, and carry out afterwards any making good or decorator's work as required; and BT will not be liable for any failure to provide Service which is due or mainly due to the requirements described in Sub-clauses 4.1 (a), (b), (c) and (d) not being met in accordance with timescales as set out in the Implementation Plan or not being maintained for the duration of the Contract, in each case to the extent that such requirements are not met or maintained. 4.2 The Customer's Content Signals at the Distribution Input Interfaces will be delivered in compliance with the specifications and standards described in Schedule 8. Whilst it is acknowledged that failure to provide continuous Customer's Content Signals does not constitute a breach of this Contract, the Customer will use reasonable endeavours to provide continuous Customer's Content Signals at the Distribution Input Interfaces. BT will not be liable for any failure to provide Service which is due 13 or mainly due to Customer's Content Signals not being delivered continuously at the Distribution Input Interfaces, and/or not being delivered in compliance with the specifications and standards described in Schedule 8, in each case to the extent that Customer's Content Signals are not so delivered. The Customer acknowledges that BT is not responsible for delivery of the Customer's Content Signals up to the Distribution Input Interfaces nor for onward carriage of the Customer's Content Signals from the Distribution Output Interfaces nor for any payments in relation thereto. 4.3 The Customer is responsible for the BT Equipment at all Sites and must not add to, modify or in any way interfere with such BT Equipment, nor allow anyone else (other than someone authorised by BT) to do so. The Customer will be liable to BT for any loss of or damage to such BT Equipment, except where such loss or damage is due to fair wear and tear, an event covered by Clause 13, or is caused by BT or anyone acting on BT's behalf. 4.4 BT will not be liable for any failure to provide Service which is due or mainly due to any interference, modification, addition to, or loss or destruction of, BT Equipment at any Site except where such loss or damage is due to fair wear and tear or is caused by BT or anyone acting on BT's behalf. 5. CONNECTION OF EQUIPMENT TO THE SERVICE 5.1 Any equipment connected to or used with the Service must be connected and used in accordance with any instructions, safety and security procedures applicable to the use of that equipment. 5.2 Any equipment which is attached (directly or indirectly) to the Service must be technically compatible with the Service and approved for that purpose under any relevant legislation. 14 6. ACCESS AND SITE REGULATIONS 6.1 In order to be able to provide the Service, BT requires the Customer (at its own expense) to seek to arrange for access, for anyone duly authorised for this purpose by BT, to any Site and any other premises outside BT's control, at all reasonable times. During a period from 3 months prior to each Service Preliminary Testing Date to each Service Delivery Date, the Customer will seek to arrange continuous 24-hour access for BT to relevant Sites, but in any event BT will require a minimum level of access to relevant Sites as described in Schedule 5. Subsequently, to carry out any major planned works or maintenance, BT will require 24-hour access at Sites from time to time on giving 3 days' notice. BT may also require immediate 24-hour access at Sites to rectify faults in Service. Otherwise, BT will normally only require access during its usual working hours but may, on reasonable notice, require access at other times which the Customer will seek to arrange. 6.2 BT employees and anyone acting on BT's behalf will observe the Customer's, or the relevant Site owner's, reasonable Site regulations in force from time to time as advised in writing to BT or drawn to BT's attention at the Site. In the event of any conflict between such Site regulations and this Contract, this Contract will prevail. 6.3 The Customer will provide a suitable and safe working environment at all Sites for BT employees and anyone acting on BT's behalf. 6.4 BT will not be liable for any failure to provide Service which is due or mainly due to the access requirements described in Sub-clause 6.1 not being met, to the extent that such requirements are not met, or to a suitable and safe working environment not being provided for BT employees or for anyone acting on BT's behalf at any Site, to the extent that such environment is not provided. 15 7. USE OF THE SERVICE 7.1 It is the Customer's responsibility to obtain and keep in force any licence necessary for the Customer to use the Service, and not to permit any third party to use the Service where such third party does so in the absence of, or in breach of, any licence necessary for it to do so. Without prejudice to the generality of the foregoing, this includes any licence or consent required from a Broadcasting Authority. 7.2 The Service must not be used in a way that: (a) places BT in breach of BT's Licence, or in breach or contravention of the Telecommunications Act 1984, or of the Broadcasting Acts 1990 or 1996, or gives rise to proceedings being taken against BT under Section 13 of the Broadcasting Act 1990; or (b) does not comply with any advice given by BT under Sub-clause 2.5 or which does not comply with Clause 5. 7.3 The Customer must indemnify BT against any claims or legal proceedings which are brought or threatened against BT : (a) by any third party because the Service is used in breach of Sub-clause 7.1 or 7.2; or (b) by any third party the Customer permits to use the Service if the Service not available for use by that third party because of any failure of the Service; or (c) by any third party because the Customer's Content Signals are in breach of any duty of confidentiality or privacy, or infringe or prejudice any intellectual property rights, or are defamatory or obscene, or are otherwise unlawful. 16 7.4 (a) Where any of such claims or proceedings described in Sub-clause 7.3 are of a criminal nature, or are likely to affect BT's Licence or any rights or obligations of BT arising out of BT's Licence, or BT's compliance with, breach or contravention of, or exercise of any rights under, the Telecommunications Act 1984 or the Broadcasting Acts 1990 or 1996, BT will retain conduct and control of such claims or proceedings but it will be a condition of this indemnity that BT will notify the Customer promptly in writing (so far as practicable) of any such claims or proceedings, make no admission in relation to the same without prior consultation with the Customer, and keep the Customer as fully informed as practicable as to the progress of such claims or proceedings. (b) In relation to any other such claims or proceedings, it will be a condition of this indemnity that BT must :- (i) notify the Customer promptly in writing of such claim or proceeding; (ii) make no admission in relation to the same; (iii) allow the Customer to conduct all negotiations and proceedings, subject to regular consultation with BT, and give the Customer all reasonable assistance in doing so (the Customer will pay BT's reasonable costs and expenses for such assistance). 7.5 If as a result of use of Service in contravention of Sub-clause 7.1 or 7.2 BT is prevented by an injunction or other order of a court of competent jurisdiction from providing the Service, or receives an order or instruction from a competent authority to cease providing the Service, or, in its reasonable opinion, after consultation with the Customer, is exposed to criminal liability if it continues to provide the Service, without prejudice to its right to terminate this Contract BT may suspend the Service until such court order is lifted or, in the case of criminal liability, BT receives such 17 assurances as BT reasonably considers to be sufficient that there will be no criminal liability arising from restoration of the Service. 7.6 The limitations and exclusions of liability contained in Clause 12 do not apply to this Clause. 8. INTELLECTUAL PROPERTY RIGHTS 8.1 Where software is provided to enable the Customer to use the Service, BT grants the Customer a non-exclusive, non-transferable licence to use the software for that purpose. 8.2 The Customer will not, without BT's prior written consent, copy or (except as permitted by law) decompile or modify the software, nor copy the manuals or documentation. The Customer will be entitled to a minimum of 3 copies of appropriate software, manuals and documentation. 8.3 The Customer will sign any agreement reasonably required by the owner of the copyright in the software to protect the owner's interest in that software, provided this does not result in any adverse financial consequences for the Customer. 9. INTELLECTUAL PROPERTY RIGHT INDEMNITIES 9.1 BT will indemnify the Customer against all claims and proceedings arising from infringement of any intellectual property rights by reason of BT's provision of the Service to the Customer. As a condition of this indemnity the Customer must: (a) notify BT promptly in writing of any allegation of infringement; (b) make no admission relating to the infringement; (c) allow BT to conduct all negotiations and proceedings, subject to regular consultation with the Customer, and give BT all reasonable assistance in 18 doing so (BT will pay the Customer's reasonable costs and expenses for such assistance); and (d) allow BT to modify the Service, or any item provided as part of the Service, so as to avoid the infringement, provided that the modification does not materially affect the performance of the Service or increase the Customer's costs. For these purposes any reduction in availability of Service will be regarded as material. 9.2 The indemnity in Sub-clause 9.1 does not extend to infringements caused by any Customer equipment, software, or services, or any combination of them, used in conjunction with the Service, except in all cases where such matters are permitted under this Contract. The Customer will indemnify BT against all claims, proceedings and expenses arising from such infringements on the same terms (mutatis mutandis) as the indemnity by BT contained in Sub-clause 9.1. 9.3 The limitations and exclusions of liability contained in Clause 12 do not apply to this Clause. 10. CONFIDENTIALITY 10.1 The parties will keep in confidence any information (whether written or oral) of a confidential nature (including software and manuals) obtained under this Contract and will not disclose that information to any person, other than those persons listed in Schedule 9 who need to know the information, without the written consent of the other party. 10.2 This Clause 10 will not apply to: (a) any information which has been published, other than through a breach of this Contract; (b) information lawfully in the possession of the recipient before the disclosure under this Contract took place; 19 (c) information obtained from a third party who the recipient reasonably believed was free to disclose it; and (d) information which a party is required to disclose to a competent regulatory authority, or information which a party is requested to disclose and, if it did not, could be required by law to do so. 10.3 This Clause 10 will remain in effect for as long as the information remains confidential, unless the parties otherwise agree. 11.

BT may charge daily interest on late payments at a rate equal to 4% per annum above the base lending rate of Midland Bank plc. 12. LIMITATION OF LIABILITY 12.1 BT accepts liability for late provision and the quality of the Service, other than where caused by an event covered by Clause 13, but only to the extent stated in Sub-clauses 2.2 and 2.3 and Schedule 3. 12.2 Each party accepts unlimited liability for death or personal injury resulting from its negligence. Sub-clauses 12.3 and 12.4 do not apply to such liability. 12.3 Except for the Customer's obligations under Clauses 7, 11 and 15 and Schedule 2, and BT's obligations under Clause 9, neither party will be liable to the other, either in contract, tort (including negligence) or otherwise for any direct or indirect loss of profits, business or anticipated savings, nor for any indirect or consequential loss or damage. 20 12.4 Except for the Customer's obligations under Clauses 7, 11 and 15 and Schedule 2, and BT's obligations under Clause 9, Sub-clauses 2.2 and 2.3 and Schedule 3, each party's liability to the other in contract, tort (including negligence) or otherwise in relation to this Contract is limited to (Pounds)2 million for any one incident or series of related incidents and to (Pounds)4 million for all incidents in any period of 12 months. 12.5 Each provision of this Contract, excluding or limiting liability, operates separately. If any part is held by a court to be unreasonable or inapplicable, the other parts will continue to apply. 13. MATTERS BEYOND EITHER PARTY'S REASONABLE CONTROL 13.1 If either party is unable to perform any obligation under this Contract because of a matter beyond that party's reasonable control (for the purposes of this Clause 13, a "Force Majeure event"), such as lightning, flood, exceptionally severe weather, fire, explosion, war, civil disorder, or acts of local or central Government or other competent authorities or events beyond the reasonable control of that party's suppliers, that party will have no liability to the other for that failure to perform. The period of such excused non-performance will be limited to the duration of the Force Majeure event, and the party unable to perform any obligation because of the Force Majeure event will give prompt notice to the other of any claim that the performance of its obligations under this Contract is prevented or adversely affected by a Force Majeure event (giving details so far as practicable of the nature of the Force Majeure event preventing or adversely affecting performance and the estimated duration of non- performance), will give similar notice when its performance is resumed or ceased to be adversely affected, and will use all reasonable endeavours to recommence performance as soon as practicable, to mitigate and eliminate the consequences of the Force Majeure event, and to inform the other party of the steps which it is taking or proposing to take to do so. 21 13.2 In the event of any failure by BT to provide Service to any single Region or to all Regions because of a Force Majeure event, except for any such Force Majeure event that also constitutes a breach by the Customer of its obligations under this Contract, or a failure to meet BT's requirements as described in Clauses 4 and 6, or an event described in Sub-clause 4.4 (for the purposes of this Clause 13, an "Excluded Event") :- (a) BT will consider all practicable options, depending on the nature and extent of any such failure, that are available to restore Service at the earliest practicable opportunity, including the use of alternative temporary facilities. Where BT considers the use of alternative temporary facilities would achieve an earlier restoration of Service than the repair of the normal facilities used to provide Service, BT will use all reasonable endeavours to provide such alternative temporary facilities as soon as reasonably practicable to provide the Service. Such alternative temporary facilities will be deemed to be acceptable if they meet the Acceptance Criteria; (b) where BT is unable to either repair the normal facilities used to provide Service or provide such alternative temporary facilities within 42 days of the commencement of the non-performance, the Customer will be entitled, by written notice expiring at the end of such 42-day period, to require this Contract to be amended such that the part of the Service affected by such non-performance is removed from this Contract and the Customer and BT are each relieved of their respective obligations to pay for and provide the part of the Service affected by such non-performance for the remainder of the term of the Contract; (c) the Customer will only be liable to pay 50% of the annual rental charges (apportioned on a daily basis over a year) applying to the parts of the Service affected by such failure for the duration of such failure. 22 13.3 For the avoidance of doubt, the provisions of Sub-clause 13.2 will not apply in the event of any failure by BT to perform any obligations because of an Excluded Event, and in such a case the Customer will remain liable for payment of the full Charges. 14. ESCALATION AND DISPUTE RESOLUTION 14.1 If a dispute arises between the parties to this Contract, the parties will use their reasonable endeavours to settle the dispute in accordance with the following procedures: (a) a dispute which has not been settled by the Customer's representative and the BT representative within 7 days of the matter being raised, may be escalated by either party to the first level by written notice to the other party; (b) if the dispute is not resolved at the first level within 7 days of escalation either party may refer the dispute to the second level. The parties' representatives and the people to whom a dispute must be escalated at the first and second levels are as notified by either party to the other from time to time. 14.2 If the dispute is a technical dispute and is still not resolved 28 days after escalation to the second level then the dispute may be referred to a single arbitrator to be agreed by BT and the Customer, or , failing agreement, to be appointed by the President of the Institution of Electrical Engineers, in accordance with and subject to the provisions of the Arbitration Acts 1950 to 1979 or any statutory modification or re- enactment of those Acts. 14.3 If a dispute is other than a technical dispute and is not resolved after the procedures set out in Sub-Clause 14.1 have been followed then, if the parties agree, the dispute will be referred to a mediator: 23 (a) the mediator will be appointed by agreement of the parties. In the event of a failure to agree within 3 days of a proposal by one party, the mediator will be appointed by the Centre for Dispute Resolution (CEDR); (b) within 14 days of the appointment of the mediator the parties will meet with the mediator in order to agree the procedure to be adopted for the negotiations; (c) all negotiations connected with the dispute will be conducted in confidence and without prejudice to the rights of the parties in any further proceedings; (d) if the parties reach agreement on the resolution of the dispute the agreement will be put in writing and once signed by the parties will be binding on them; (e) if the parties are not prepared to agree to the dispute being referred to a mediator or fail to reach agreement within 2 months of the mediator being appointed then either party may exercise any remedy that it has under this Contract. 15. TERMINATION OF THIS CONTRACT BY NOTICE 15.1 This Contract will terminate automatically at the expiry of the Minimum Period unless both parties agree to extend or renew it, provided that the Customer may extend the duration of the Minimum Period of this Contract for a period of up to nine months upon giving BT written notice not later than the eleventh anniversary of the first Service Delivery Date. 15.2 If the Customer terminates this Contract or the Service during the Minimum Period (other than in accordance with a right under in this Contract) the Customer must pay BT a sum equal to the Charges for the remaining part of the Minimum Period, discounted, in recognition of the Charges being paid in 24 a lump sum to BT upon termination, by using the 3 month Sterling London Interbank Offer Rate quoted by Midland Bank plc, London on the date of termination. Such sum will be paid by the Customer within 45 days of BT's invoice, and BT may charge daily interest on late payment in accordance with Sub-clause 11.2. 15.3 In mitigation of BT's losses on termination in breach by the Customer as described in Sub-clause 15.2 :- (a) BT will use all reasonable endeavours to contract to provide DTTV Service to other customers using the facilities used to provide the Service under this Contract, provided that BT will not be required to contract on a basis other than the standard prices, terms and conditions applicable to the DTTV Service. Provided the Customer has paid the sum described in Sub-clause 15.2, BT will pay to the Customer the money it obtains from any such other customer(s) (less BT's reasonable costs and expenses (if any) incurred in contracting with any such customer(s)) to the extent that the money obtained from such other customer(s) relates to facilities utilised to provide the Service under this Contract and provided that such payment(s) will not exceed in total the sum paid by the Customer under Sub-clause 15.2. Such payment(s) will be made by BT within 45 days of receipt, and the Customer may charge interest on late payment at a rate equal to 4% per annum above the base lending rate of Midland Bank plc; and (b) If BT has not been able to so contract with another customer within 12 months of such termination in breach by the Customer, BT will use all reasonable endeavours to redeploy and reutilise any of the facilities used to provide Service under this Contract on reasonable terms, subject to any regulatory considerations that may apply. Provided the Customer has paid the sum described in Sub-clause 15.2, BT will pay to the Customer any money it obtains from such redeployment or reutilisation less BT's reasonable costs and expenses (if any) incurred in such redeployment or reutilisation, provided that such payments will not exceed in total the sum paid by the Customer under Sub-clause 15.2. Such payment(s) will be made by BT 25 within 45 days of receipt, and the Customer may charge interest on late payment at a rate equal to 4% per annum above the base lending rate of Midland Bank plc. 15.4 In addition to any rights of termination specified elsewhere in this Contract, if the industry for digital terrestrial television services as a whole fails, such that all holders of Broadcasting Authority licences or other UK government authorisations permanently cease to provide digital television services and all Broadcasting Authority licences or other UK government authorisations are permanently terminated, surrendered, withdrawn or otherwise revoked or ceased, then :- (a) if such event occurs on or after the fifth anniversary of the first Service Delivery Date, the Customer will be entitled to terminate the Contract on giving BT twelve calendar months' written notice, without liability for any further payment other than the Charges payable during the notice period; or (b) if such event occurs prior to the fifth anniversary of the first Service Delivery Date, the Customer may terminate this Contract on one month's written notice, subject to payment, prior to expiry of the notice, of a sum equivalent to all Charges payable by the Customer from the date such notice was given up to the fifth anniversary of the first Service Delivery Date, discounted by using the 3 month Sterling London Interbank Offer Rate quoted by Midland Bank plc, London on the date of termination. 15.5 If the Customer (other than as a result of an event described in Sub-clause 16.1 (d) or as a result of any breach by the Customer of its Broadcasting Authority licence or other UK government authorisation) permanently ceases, in good faith, to provide one or more of the DTTV Multiplex Services for which it has a Broadcasting Authority licence or other UK government authorisation, such that its Broadcasting Authority licence or other UK government authorisation is permanently terminated, surrendered, withdrawn or otherwise revoked or ceased, and is not 26 transferred or reissued to a connected company, then :- (a) the Customer will use all reasonable endeavours in good faith to effect a transfer to any replacement licensee or other UK government authorisee of the part of the Service used to provide such permanently ceased DTTV Multiplex Service, but if such transfer does not take place, then (b) the Customer will be entitled, by written notice, to require this Contract to be amended such that the part of the Service used to provide such permanently ceased DTTV Multiplex Service is removed from this Contract and the Customer and BT are each relieved of their respective obligations to pay for and provide such part of the Service from the fifth anniversary of the first Service Delivery Date, or if such notice is given after the fifth anniversary of the first Service Delivery Date, from twelve calendar months from the date of the notice. 16. BREACHES OF THIS CONTRACT 16.1 Either party may terminate this Contract without notice if the other: (a) commits a material breach of this Contract, which is capable of remedy, and fails to remedy the breach as soon as is reasonably practicable or in any event within 30 days of a written notice to do so; or (b) commits a material breach of this Contract which cannot be remedied; or (c) is repeatedly in breach of this Contract; or (d) is the subject of a bankruptcy order, or becomes insolvent, or makes any arrangement or composition with or assignment for the benefit of their creditors, or goes into voluntary (otherwise than for reconstruction or 27 amalgamation) or compulsory liquidation or a receiver or administrator is appointed over their assets. 16.2 If the Customer commits any of the acts detailed in Sub-clauses 16.1 (a) or (c), or an event detailed in Sub-clause 16.1 (d) happens to the Customer, (except for acts or events covered by Sub-clause 7.5), BT may suspend the Service without prejudice to its right to terminate this Contract, provided that in the case of a suspension under Sub-clauses (a) or (c) BT must, after the expiry of 45 days, either resume Service or exercise its right to terminate this Contract. Where the Service is suspended under this Clause, the Customer must pay the charges for the Service until this Contract is terminated. 16.3 If this Contract is terminated by BT during the Minimum Period because of an event specified in Sub-clause 16.1, the Customer must pay BT a sum calculated in accordance with Sub-clause 15.2. 16.4 If either party delays in acting upon a breach of this Contract that delay will not be regarded as a waiver of that breach.

CHANGES TO THIS CONTRACT 17.1 Changes to the Service (a) If the Customer wishes to change the location of the Playout Centres from which, or the Transmitter Sites to which, the Service is provided, or to make any other changes to the Service, it must notify BT in writing. (b) The parties will discuss the proposed change. (c) Within a reasonable time of receipt of a proposed change, or the date of the discussions under Sub-clause 17.1(b), BT will notify the Customer in writing whether or not BT can accommodate the change, and of the likely 28 timescale, financial, contractual, technical and other effects (if any) of the proposed change. (d) Within a reasonable time of notification of the effects of a proposed change the Customer will advise BT whether it wishes this Contract to be amended to incorporate the change and BT will carry out such change on the terms agreed. PROVIDED THAT BT agrees that, in any event :- (i) where the Customer requires the Service to be provided to additional transmitter sites (other than the Transmitter Sites), subject to the maximum specified in paragraph 2 of Schedule 2, the formula to be applied to calculate the Charges for additional transmitter site access payable by the Customer in such circumstances will be that set out in paragraph 2 of Schedule 2, and BT will comply with any such request subject to completion of the appropriate Contract Change Order and to six months' prior written notice of the new Service Preliminary Testing Date; (ii) where the Customer requests BT to reconfigure the Service to meet any changes to its (or its own customer DTTV Multiplex Service operators') regional distribution requirements, BT will consider such requests and if feasible, carry out any such changes, provided the Customer will pay any reasonable additional charge; (iii) where appropriate, if the Customer requests BT to make changes to the Service which are for the benefit of one of the Customer's own customer digital television multiplex operators, any proposals BT makes for consequential adjustment of the Charges will be calculated solely in relation to such customer of the Customer. 29 17.2 Changes to dates 17.2.1 Where the actual industry launch date for digital terrestrial television services, as agreed with all other customers for the DTTV Service, is later than 31 October 1998, the Customer will be entitled to substitute the earlier of such actual industry launch date or 31 January 1999 for 31 October 1998 in the definition of the Minimum Period in Clause 1, so that the Minimum Period expires of the 12th anniversary of such substituted date, by giving three months' prior written notice to BT expiring not later than 31 October 1998. Where such notice is given:- (a) the Service Preliminary Testing Dates, the Service Full Testing Dates, and the Service Delivery Dates (both for Phase 1 and Phase 2 Transmitter Sites) will each be commensurately deferred unless the parties agree otherwise; and (b) amendments reflecting such deferral of dates will be deemed to be made to Part 1 of Schedule 3, such that Late Delivery Payments will apply only in respect of the respective deferred dates; and (c) the Implementation Plan will be amended to reflect such deferral of dates. 17.2.2 If the Customer is unable to use the Service at any particular Phase 2 Transmitter Site due to inability to obtain frequency clearance to transmit from such Phase 2 Transmitter Site, then, subject to giving four months prior written notice expiring not later than the Service Preliminary Testing Date for such Phase 2 Transmitter Site, the Customer may either postpone delivery of Service to such Phase 2 Transmitter Site, or substitute an alternative transmitter site for delivery of the Service, provided that:- (a) When frequency clearance is obtained in respect of such Phase 2 Transmitter Site or any substituted transmitter site, the Customer will give BT six months' prior written notice of the new Service Preliminary Testing Date applying to the provision of Preliminary Testing Service to such 30 Phase 2 Transmitter Site, and the new Service Full Testing Date for provision of Full Testing Service to such deferred or substituted Phase 2 Transmitter Site will be not earlier than 31 days after the new Service Preliminary Testing Date, and the new Service Delivery Date for provision of fully operational Service to such deferred or substituted Phase 2 Transmitter Site will not be earlier than 30 days after the new Service Full Testing Date; and (b) amendments reflecting such deferral of dates will be deemed to be made to Part 1 of Schedule 3, such that Late Delivery Payments will apply only in respect of any delays beyond the respective deferred dates; and (c) the Implementation Plan will be amended to reflect such deferral of dates. 17.2.3 If any changes are agreed to any of the Service Preliminary Testing Dates, Service Full Testing Dates, or Service Delivery Dates in relation to any Transmitter Site, then such changes will, unless otherwise agreed, have effect to change such other Dates in relation to that Site to reflect their current respective intervals, and to invoke a review of the Implementation Plan in order to make appropriate changes to reflect such revised Dates. 17.3 At agreed intervals of not less than 4 years the parties will collaborate on a technical review of the BT Equipment and other distribution equipment available on the market. Where opportunities are identified, from such technical review, to improve or enhance the Service, or to operate the Service more cost effectively the parties will co-operate in good faith. Should there be such an opportunity to operate the Service more cost-effectively BT will share with the Customer and other customers for the DTTV Service any benefits arising from such technology improvement with due regard to the need for BT to achieve a reasonable rate of return on both the item(s) of new BT Equipment which is/are required to be installed and of the original BT Equipment which is/are required to be replaced or is/are rendered obsolete as a result of the implementation of such improvements. 31 17.4 Where the parties agree a change to this Contract it will be recorded in writing on a Contract Change Order Form in the form set out in Schedule 10 and will then form part of this Contract when signed by both parties. 18. INSURANCE Throughout the period of this Contract both parties will maintain appropriate insurance against loss, damages, claims or actions arising from personal injury, public liability and any other liability for which either is required by law to insure. 19. ASSIGNMENT Neither party may assign or transfer any of their rights or obligations under this Contract, without the written consent of the other, except that BT may assign or transfer its rights or obligations (or both) to a BT Group Company without consent, and BT will not unreasonably refuse consent to the Customer's transferring its rights and obligations under this Contract to another DTTV Multiplex Service operator or to a Group Company of the Customer. 20. ENTIRE AGREEMENT 20.1 This Contract contains the whole agreement between the parties and supersedes all previous written or oral agreements relating to its subject matter. 20.2 The parties acknowledge and agree that: (a) they have not been induced to enter into this Contract by any representation, warranty or other assurance not expressly incorporated into it; and (b) in connection with this Contract their only rights and remedies in relation to any representation, warranty or other assurance are for breach of this 32 Contract and that all other rights and remedies are excluded, except in the case of fraud. 21. NOTICES Notices given under this Contract must be in writing and may be delivered by hand or by courier, or sent by telex or first class post to the following addresses: (a) to BT: Senior Business Manager Terrestrial Services, Broadcast Services, 125 Shaftesbury Avenue, London WC2H 8BE or any alternative address which BT notifies to the Customer; (b) to the Customer at the address to which the Customer asks BT to send invoices, the address of the Customer's premises or, if the Customer is a limited company, its registered office.

GENERAL 1.1 The Service is a uni-directional service, provided via a diversely routed network for the distribution of the Customer's Content Signals provided from a Distribution Input Interface to a Distribution Output Interface, in accordance with the description as detailed in this Schedule and the Functional Design Specification. 1.2 The DTTV Distribution Network will provide capacity for the carriage of Service Information ("SI") from a central SI Collation Site, which will be located at either British Digital Broadcasting Plc's premises at Marco Polo House, 346, Queenstown Road, London SW8 4NE, or at the Channel 4 Television Corporation's premises at Channel 4, 124, Horseferry Road, London SW1P 2TX (to be agreed) ("the central SI Collation Site"), to Transmitter Sites designated as Service Insertion Points ("SIPs"). BT will accept the Customer's DTTV Multiplex Services feeds and deliver these signals to agreed main and daughter Transmitter Sites. The SI capacity will be diversely routed. The network design will ensure that the two feeds are physically and electrically separate. BT will provide 5 Mbit/s of capacity relating to all digital multiplexes from the central SI Collation Site throughout the DTTV Distribution Network for use by all customers for the DTTV Service. Part 4 of Schedule 1 provides a list of SIP Transmitter Sites and their associated daughter Transmitter Sites, which may be subject to review, following discussion by the Digital Network Group. The industry's arrangements for the carriage of SI have yet to be defined. The exact arrangements will be defined when the solution is known. Provided that such arrangements are notified to BT by not less than four 35 months prior to the first Service Delivery Date, BT will provide capacity to the Customer for carriage of SI to each Transmitter Site by its respective Service Delivery Date. 1.3 Service monitoring and management systems will provide both BT and the Customer with appropriate network status and management information in accordance with the Network Management Service described in Schedule 7. The Network Management Service will be available to each Transmitter Site from its respective Service Full Testing Date. 1.4 Initially, the Service will be provided via two unswitched DVB ASI transport streams at each Distribution Output Interface, but BT will provide, by no later than the expiry of twelve calendar months after the first Service Delivery Date, an output switching facility at each Transmitter Site and RPOC (but not at Playout Centres) providing two continuous DVB ASI transport streams such that, in the event of a single failure, output switching and restoration can take place, provided that, in respect of Transmitter Sites where the Service Full Testing Date occurs after the expiry of twelve calendar months after the first Service Delivery Date, such switching facility will be made available on their respective Service Full Testing Dates. Such switching facility will not include any switching or restoration associated with SI. 2. CUSTOMER-SPECIFIC SERVICE DESCRIPTION 2.1 Service for Customer's Content Signals originating from BDB 2.1.1 The Customer will provide two identical feeds of each of the Customer's Content Signals in respect of each of BDB's three DTTV Multiplex Services to BT Distribution Input Interfaces (designated Feed A and Feed B) for interconnection with BT provided ASI multiplexes located within the BDB London Playout Centre detailed in Schedule 1, Part 3, Table 1. 2.1.2 Access to the DTTV Distribution Network will be provided from BDB's London Playout Centre via seperately routed fibre optic circuits.

Y is then multiplied by the number of Transmitter Sites to which Service is provided. 1.2.4 Total Service Rental Charges (on the basis that all Service Delivery Dates are met by BT) at 1998 prices are therefore as follows: Description Year 1 Year 2 Year 3 ----------- ------ ------ ------ onwards ------- Access Charges [*] [*] [*] National Distribution Charges [*] [*] [*] Local Distribution Charges [*] [*] [*] TOTAL [*] [*] [*] In the event of any changes to the delivery programme, the Local Distribution Charges may vary from those indicated in the above tabulation, as the Local Distribution Charges are payable (subject to 1.4 (b) below) from the relevant Service Delivery Dates. 1.3 Charges will be annually increased on each anniversary of the first Service Delivery Date in accordance with the following formula: [*] 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. 58 C1 = [*] where: C1 = Charges for the current year, C0 = Charge for the previous year, X = The arithmetic mean of the percentage increases in the Retail Price Index for each of the 12 months immediately preceding each anniversary of the first Service Delivery Date over the Retail Price Index for each of the corresponding 12 months immediately preceding those 12 months. PROVIDED THAT:- (a) in the event that the above formula results in a negative or zero figure increase for any period, then there will be no increase for that period; (b) in the event that the RPI is not available in time for BT to calculate a revised Service Rental Charge on an anniversary of the first Service Delivery Date, then BT will invoice the Customer at the previous year's Service Rental Charge until the RPI is available, when an appropriate adjustment will be made to a following invoice; (c) should the RPI cease or fail to be published or should any changes occur to the basis of the RPI, BT and the Customer will make a fair and reasonable adjustment to RPI or, if appropriate, substitute a revised formula which in either event will have substantially the same effects as those specified in this paragraph 1.3. 1.4 The terms of payment for the Charges as above will be as follows:- (a) the Service Connection Charge under 1.1(a) above will be payable in two equal instalments on the first and second anniversaries of the first Service Delivery Date; [*] 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. 59 (b) The Service Rental Charge under 1.1(b) above will be payable every two calendar months in advance, with the first payment being due on the first Service Delivery Date, PROVIDED THAT if Service is not provided to a Transmitter Site on the relevant Service Delivery Date and the delay is due to BT, the Service Rental Charge is payable from the date on which Service is provided to that Transmitter Site ("the Operational Service Date"). 2. ADDITIONAL TRANSMITTER SITES The formula to be used to calculate the Charges for additional transmitter site access in accordance with Sub-clause 17.1 (i) will be that the Service Rental Charges for Service to the additional transmitter sites will be based on the Service Rental Charges as described in paragraph 1 above, but subject to a maximum annual charge of [*] at 1998 prices (plus value added tax) per annum per site, such maximum figure being subject to annual indexation in accordance with paragraph 1.3 above from the first anniversary of the first Service Delivery Date to the time the Service is provided to the additional transmitter site(s), provided that such maximum annual charge will only apply to up to an aggregate maximum of 24 additional transmitter sites nominated by the Customer, and where all such sites and circuits to them are within BT's Licensed area in the United Kingdom. The additional Service Rental Charges for Service being provided to such additional transmitter sites will be subject to annual increase in accordance with paragraph 1.3 above. The annual charge referred to above will be apportioned per DTTV Multiplex Service (currently 5) according to any shared utilisation with other customers for the DTTV Service.

GENERAL In the event of delivery of Preliminary Testing Service after the Service Preliminary Testing Dates, of delivery of Full Testing Service after the Service Full Testing Dates, and/or of delivery of full Service after the Service Delivery Dates, where the delay is due to BT, the Customer will be entitled to claim Late Delivery Payments from BT calculated and payable in accordance with this Part 1 of Schedule 3. BT will, wherever practicable, co-ordinate its activities with the transmitter providers' build project timetables and to this intent will use reasonable endeavours to provide relevant Service to the Phase 1 Transmitter Sites (as defined below), subject to requirements in Clauses 4 and 6 being met within appropriate earlier timescales, one month prior to relevant Dates, but will not be liable for Late Delivery Payments (or at all) in the event of any such Service not being available on any such Date. 2. LATE DELIVERY PAYMENTS FOR LATE DELIVERY OF PRELIMINARY TESTING SERVICE AND FULL TESTING SERVICE TO PHASE 1 TRANSMITTER SITES 2.1 Where Preliminary Testing Service is not made available to all of the Transmitter Sites listed under the heading Phase 1 in Part 2 of Schedule 1 (the "Phase 1 Transmitter Sites") by midnight on their common Service Preliminary Testing Date, and/or where Full Testing Service is not made available to all of the Phase 1 Transmitter Sites by midnight on their common Service Full Testing Date, where the delay is due to BT in each case, Late Delivery Payments will be calculated as follows:- 62 2.2 For Preliminary Testing Service, Late Delivery Payments will be based on Table 1A below. The amount payable will be a single payment, being the figure shown opposite the Day on which Preliminary Testing Service is provided to all the Phase 1 Transmitter Sites, multiplied by the number of DTTV Multiplex Services for which the Customer (or, where appropriate, the Customer's own customer DTTV Multiplex Service providers) have Broadcasting Authority licences (not exceeding 4) and which are affected by the delay ("the Multiplier"). Where Preliminary Testing Service is not provided to all the Phase 1 Transmitter Sites until after Day 30, the amount payable will be the amount shown opposite Day 30, multiplied by the Multiplier. 2.3 For Full Testing Service, Late Delivery Payments will be based on Table 1B below. The amount payable will be a single payment, being the figure shown opposite the Day on which Full Testing Service is provided to all the Phase 1 Transmitter Sites, multiplied by the Multiplier. Where Full Testing Service is not provided to all the Phase 1 Transmitter Sites until after Day 30, the amount payable will be the amount shown opposite Day 30, multiplied by the Multiplier. 2.4 If the Customer claims Late Delivery Payments under paragraphs 2.1 to 2.3 above, the Customer will not be entitled to receive the relevant Service to any of the Phase 1 Transmitter Sites. However, if the Customer wishes to accept provision of the relevant Service to some, but not all, of the Phase 1 Transmitter Sites on the relevant Date, then the Customer will be entitled to claim Late Delivery Payments of a pro-rata proportion of the relevant sum shown in Table 1A or B (as appropriate), where the amount payable will be calculated as follows:- 63 Number of Phase 1 Figure shown Transmitter Sites in opposite Day respect of which on which relevant relevant Service is Service is not available provided to all _________________ X Phase 1 X Multiplier Total number of Transmitter Phase 1 Transmitter Sites (or if after Sites Day 30, then figure shown opposite Day 30) 2.5 Any Phase 1 Transmitter Sites for which a Service Preliminary Testing Date and/or a Service Full Testing Date are either not agreed, or are not common to the Service Preliminary Testing Date or the Service Full Testing Date for the other Phase 1 Transmitter Sites, will be deemed to be Phase 2 Transmitter Sites (see below) and accordingly Late Delivery Payments under this paragraph 2 and the following paragraph 3 will not be payable in respect of delivery of relevant Service to such Transmitter Sites. 3. LATE DELIVERY PAYMENTS FOR LATE DELIVERY OF FULL SERVICE TO PHASE 1 TRANSMITTER SITES In addition to any Late Delivery Payments payable under paragraph 2 above, for each of the Phase 1 Transmitter Sites where full Service is not provided by midnight on their common Service Delivery Date where the delay is due to BT, the Customer will be entitled to claim a further Late Delivery Payment which will be [*] per Transmitter Site per day of such delay multiplied by the Multiplier, subject to a maximum overall total daily payment for all such Transmitter Sites of [*] multiplied by the Multiplier. [*] 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. 64 4. LATE DELIVERY PAYMENTS FOR LATE DELIVERY OF PRELIMINARY TESTING SERVICE, FULL TESTING SERVICE, AND FULL SERVICE TO PHASE 2 TRANSMITTER SITES In respect of the Transmitter Sites listed under the heading Phase 2 in Part 1 of Schedule 1 or deemed to be a Phase 2 Transmitter Site under paragraph 2.5 above (the "Phase 2 Transmitter Sites"), the Customer will be entitled to claim Late Delivery Payments in accordance with either Option A or Option B as set out below, provided that the Customer elects which Option will apply prior to signature of this Contract:- OPTION A -------- The Customer will be entitled to claim Late Delivery Payments for late delivery of Preliminary Testing Service and Full Testing Service on the same basis as set out in paragraph 2 of this Part 1 of Schedule 3, but where the provisions of paragraph 2 will apply separately to each group of Phase 2 Transmitter Sites which share the same Dates, and in the case of each such group, the amounts shown in Table 1A and Table 1B are each reduced by four-fifths. Additionally, where full Service is not provided to any Phase 2 Transmitter Site by midnight on its Service Delivery Date where the delay is due to BT, the Customer will be entitled to claim a Late Delivery Payment of [*] per day of such delay multiplied by the Multiplier. OPTION B -------- No Late Delivery Payments will be payable where Preliminary Testing Service is not delivered on the Service Preliminary Testing Date, or where Full Testing Service is not delivered on the Service Full Testing Date, but where full Service is not provided to any Phase 2 Transmitter Site by midnight on its Service Delivery Date where the delay is due to BT, the Customer will be entitled to claim a Late Delivery Payment of [*] per day of such delay multiplied by the Multiplier.

In the event of any conflict between the Functional Design Specification and the Contract, the Contract will prevail. The parties recognise that the technical description and specification of the Service may change from time to time, and that any such agreed changes will be incorporated within a revised Functional Design Specification, in addition to any changes that may be agreed to the Contract consequent on such changes. 75 SCHEDULE 5 ---------- IMPLEMENTATION PLAN ------------------- BT will produce an Implementation Plan for delivery and testing of the Service, which will include timescales for fulfilment of BT and Customer requirements and obligations (including the BT requirements and Customer's obligations under Sub- clauses 4.1 and 6.1), and which both parties will use all reasonable efforts to agree as soon as practicable, PROVIDED THAT in any event the Customer acknowledges that, as a minimum:- (a) BT will require the requirements described in Sub-clause 4.1 to be fulfilled not less than two calendar months prior to the relevant Service Preliminary Testing Date at each Site; and (b) BT will require the following minimum levels of access referred to in Sub- clause 6.1:- (i) continuous 24-hour access to all relevant Sites for all internal work during a period from 2 months prior to each Service Preliminary Testing Date to each Service Delivery Date; (ii) access 7 days per week from 08.00 hours to 18.00 hours to all relevant Sites for all external work during a period from 3 months prior to each Service Preliminary Testing Date to 1 month prior to each Service Preliminary Testing Date, then continuous 24-hour access to all relevant Sites for all external work during a period from 1 month prior to each Service Preliminary Testing Date to each Service Delivery Date. If the Customer is unable to arrange access in accordance with (b) above at any Transmitter Sites, the Customer may propose an alternative detailed timetable (including proposed dates and hours of access for internal and external work) for BT's access to such Transmitter Sites. BT will review these proposals and indicate whether or not BT can accept them (which will be at BT's sole discretion) in relation to each Transmitter 76 Site. Where BT accepts such proposals, BT's requirements under Sub-clause 6.1 shall be deemed to be modified accordingly in relation to such Transmitter Site(s), and Late Delivery Payments shall apply accordingly. Where BT does not accept such proposals, BT will use reasonable endeavours to carry out the relevant work within the Customer's proposed timetable but will have no liability to the Customer for late provision of Service and accordingly no Late Delivery Payments will be payable. BT's acceptance of any such proposals will only be valid if made in writing and signed by BT's DTTV Service Project Manager, such BT DTTV Service Project Manager to be advised by BT to the Customer from time to time. 77 SCHEDULE 6 ---------- ACCEPTANCE TESTS ---------------- PART 1 : GENERAL METHODOLOGY ----------------------------- BT will conduct Acceptance Tests in accordance with the following methodology to satisfy conformance with the Acceptance Criteria. These tests will take place in four main stages:- (a) the Customer will have the built in diagnostic features of the ASI equipment demonstrated to them at BT laboratories. These features will enable remote verification that the DTTV Distribution Network is satisfying the service parameters during commissioning and through out the life of the network; (b) individual links will be commissioned by BT. Copies of the commissioning reports for each circuit within the network on which their signals are carried will be made available to the Customer; (c) the Customer's nominated representatives, in accordance with Sub- clause 3.1, will be invited to be present at a five randomly picked Transmitter Sites where the diagnostic features of the ASI equipment will again be verified with other test equipment.
