SPECIFICATIONS APPENDIX 1 Mercury-Nynex 11 November 1996 Page 1 of 7 Interconnect Agreement Appendix 1, Technical Specifications 103 APPENDIX 1 - TECHNICAL AND OPERATIONAL MATTERS 1 General 1.1 The guidelines for network performance, technical specifications, interface standards, switching principles and other technical and operational matters for the implementation of this Agreement are specified in the Manuals. These Manuals constitute best working practice but are not legally binding upon the Parties. 1.2 Each Party shall maintain a 24 hour point of contact to give operational assistance in resolving problems that arise with Calls destined to each Party's System 1.3 The Mercury System and the NYNEX System shall use digital transmission and switching technology for Interconnection. 1.4 In the practical implementation of Interconnection the Parties shall at all times apply standards and operating guidelines which in the first instance have due regard to any legal requirements imposed upon them and thereafter wherever practicable shall apply the relevant international standards (in particular but not limited to those of ITU-T). Where alternative international standards exist, in making their selection, the Parties shall give preference to those adopted by European telecommunication administrations. Where relevant international standards are not available, the Parties shall develop their own common standards or other agreed solutions. 2 Transmission and synchronization Mercury and NYNEX shall ensure that their respective Systems perform in accordance with Transmission Specification NPDS7/94/4 developed by the Network Performance Standards Group of the PNO-IG of the NICC in force at the date hereof. 3 In-Span Interconnection 3.1 Each additional Point of Connection established under this Agreement shall be In-Span Interconnection. In-Span Interconnection may be provided using either PDH or SDH terminal equipment (as agreed between the Parties) without the need for signal regeneration. 3.2 In the case of Interconnection using PDH equipment, the Parties shall agree the type and manufacturer of the optical line terminating equipment to be used by each Party. Mercury-Nynex 11 November 1996 Page 2 of 7 Interconnect Agreement Appendix 1, Technical Specifications 104 3.3 In the case of Interconnection using SDH equipment, each Party shall ensure that such equipment as used by it shall conform to the following PNO-IG technical recommendations (in force at the date hereof): 3.3.1 PNO-CSI SDH interconnection between UK Operators -Interconnect Commissioning Recommendations; 3.3.2 PNO-CSI SDH interconnection between UK Operators -Operations and Maintenance Recommendations; and 3.3.3 PNO-CSI SDH interconnection between UK Operators -Overview and Technical Recommendations. 3.4 In the case of Interconnection using SDH equipment, the Parties shall provide a single physical connection operating at the 155MBit/s STM-1 level. Ring structures using a single Mercury add drop multiplexer and one or more Points of Connection as appropriate may be employed. Any onward connections within the Mercury System may be made using PDH equipment. 3.5 Prior to establishing a Point of Connection using SDH equipment, the Parties shall agree any interworking acceptance test in addition to the normal commissioning tests. The Parties shall not exchange timing across an SDH Point of Connection until the implementation of the timing status flag has been standardised. Network management actions and reconfigurations shall not be made by one Party on the other Party's Add Drop Multiplexer. 3.6 The physical connection between each Party's System shall be made at the optical level in each Footway Box. 3.7 The specification of the cable to be used for In-Span Interconnection shall be agreed between the Parties prior to installation. Each Party shall supply, instal and test the cable from its System to the Footway Box. 3.8 The Party providing a Footway Box shall either arrange to join each Party's cable at the Footway Box or, where practical and subject to good engineering practice, shall arrange for one Party's cable to be inserted and connected directly within the other Party's building. Under such circumstances demarcation of each Party's System remains at the Footway Box. 3.9 The provider of the Footway Box shall join the duct systems at the Footway Box. Mercury-Nynex 11 November 1996 Page 3 of 7 Interconnect Agreement Appendix 1, Technical Specifications 105 3.10 All work performed on either Party's plant shall be performed to that Party's standards by that Party's approved contractors and under that Party's supervision. 3.11 Commissioning and acceptance of the interconnecting cable shall be carried out by both Parties in accordance with a cable acceptance specification to be agreed between the Parties. 3.12 The optical fibre cables shall be terminated at each end on an optical distribution frame. The optical line terminating equipment shall be connected to suitable multiplex equipment. Each Party shall be responsible for the terminal equipment at its end of the Interconnect Link, including any necessary multiplex equipment, optical distribution frame and miscellaneous items. Circuits shall conform to ITU-T Recommendations G.703 and G.704 at the interfaces to the multiplexers. 3.13 The Interconnect Link shall be jointly tested end to end using a specification to be agreed between the Parties for PDH equipment and using the PNO-IG test specification for SDH equipment. 4 Routing and Architecture 4.1 Traffic Routes shall be planned to operate so that during the busy hour a maximum of eight out of 1000 Calls shall be lost due to congestion. 4.2 Each Party shall use all reasonable endeavours to manage its System by taking real time network management actions agreed between the Parties' appropriate network management centres to protect the Systems in the event of national emergencies, System failures, mass calling events and any event having a similar impact on either System. 4.3 Wherever possible advance warning should be given to the other Party when a Party becomes aware of a mass calling event likely to introduce higher than normal traffic levels across a particular Traffic Route. 4.4 Should either Party (for the purposes of this paragraph, the "First Party") fail to take appropriate network management action or give advance warning in accordance with paragraphs 4.2 or 4.3 above then the other Party may in order to protect all or part of its System arrange to disconnect any Traffic Routes creating or helping to create such failure. Such action shall be notified to the First Party prior to disconnection. Mercury-Nynex 11 November 1996 Page 4 of 7 Interconnect Agreement Appendix 1, Technical Specifications 106 4.5 NYNEX shall use separate and dedicated Traffic Routes for emergency service traffic. The Circuits employed shall, where possible, be the signalling link circuits. Where possible, the Circuits shall be diversely routed via a second Point of Connection. 5 Signalling 5.1 In respect of the Telecommunications Services, Mercury and NYNEX shall ensure that their respective signalling arrangements between their respective Systems conform to the UK C7 signalling protocols as defined in Specifications PNO-ISO/Spec/005 Message Transmission Part and PNO-ISC/Spec/006 Interconnect User Part in force at the date hereof 5.2 Signalling links shall be carried in time slot 16 of a Circuit. Each Circuit which is required to carry signalling shall also be capable of conveying Calls. 5.3 Signalling links shall be carried in the first and second Circuit of a Traffic Route. 5.4 One pair of signalling links (always in separate Circuits and over separate physical routes where possible) shall be used for each group of up to 40 Circuits. 5.5 NYNEX and Mercury shall configure and utilise Circuits in a uni-directional manner. 5.6 In the event that the Parties agree to configure a Circuit in a bi-directional manner, either Switch may seize the free traffic channels and one or both Switches shall clear the seizure and re-attempt the Call set-up. Priority on dual seizure shall be given to Mercury. In order to minimise the number of simultaneous traffic seizures, each Switch shall search its traffic channels in the reverse sequence to the other Switch. The NYNEX Switch shall seize channels in ascending order and the Mercury Switch shall seize channels in descending order. 6 Testing 6.1 The Parties shall agree (subject as stated in paragraph 6.2) the testing required to establish an additional Point of Connection in the Interconnect Design and the testing required prior to commencing the conveyance of ISDN Calls. 6.2 The extent of the testing will be dependent on the expected impact on the Systems. At the request of either Party, the testing described below shall be undertaken. The Parties may agree a reduced level of testing, when Switches of the same type, at the same build level, have previously been successfully interconnected or where testing involves new processes, new builds or new elements from previously proven Switch types. Mercury-Nynex 11 November 1996 Page 5 of 7 Interconnect Agreement Appendix 1, Technical Specifications 107 6.2.1 Simulator Testing: this phase involves the provision of suitable simulator test results by NYNEX, to allow visibility of meaningful test results prior to the Switch being integrated into the Interconnection. 6.2.2 Switch to Switch Testing: these are provocative tests involving simulated hardware failures and Switch restarts during various phases of Call set up and various speech circuit states. The tests involve either captive Switches or operational Switches not yet carrying live traffic. Should any new feature, service or facility be introduced across the Interconnection such tests may also be required. Tests will also be necessary to prove new features and facilities. 6.2.3 Commissioning and Acceptance Testing (CAT): these are standard Traffic Route commissioning tests which will be performed whenever a new Circuit is introduced to service. For route augmentations a subset of the tests will be performed as detailed in the Mercury CAT Manual. 6.2.4 Pilot Service: this will be a period (usually several weeks) in which live traffic of all Call types is passed across the Point of Connection while statistics are gathered from the Switches to ensure satisfactory performance is obtained. (Statistics gathered are likely to be in the form of answer to seize ratios, number of Calls offered, number of Calls lost etc.) Live traffic may be substituted by traffic from a Call simulator where considered appropriate. 6.3 Suggested timescales for all of the above are as follows:- 6.3.1 simulator testing - up to 4 months; 6.3.2 Switch to Switch - up to 4 weeks; 6.3.3 commissioning (CAT) - up to 2 weeks; and 6.3.4 pilot service - up to 6 weeks. 6.4 Timescales specified in paragraphs 5.4.1 and 5.4.4 above will be dependent on the new Switch type, NYNEX's own test plan and the level of testing agreed. 6.5 The Parties shall both confirm in writing when such testing has been completed satisfactorily. 7 Numbering Mercury-Nynex 11 November 1996 Page 6 of 7 Interconnect Agreement Appendix 1, Technical Specifications 108 7.1 Both parties shall conform to the national and international numbering formats in place from time to time. 7.2 Both parties shall at all times notify the other in writing giving details of new number ranges allocated to them and amendments to existing number ranges. 7.3 When conveying a Call to the other party's System, each party shall convey to the other the complete number including the national and international dialling prefix. 7.4 Each party (for the purpose of this paragraph the "First Party") shall use its reasonable endeavours to notify the other party in writing, giving details of new number ranges allocated to the First Party and amendments to or deletions of existing number ranges, in each case at least 30 days prior to the implementation of the same.

In the event of a failure to agree, a Footway Box shall be provided and owned by the Party receiving a request for an additional Point of Connection. Each Footway Box may be used by the Party owning it to establish points of connection with other Operators. 1.5 The Parties shall use their respective reasonable endeavours to agree the Interconnection Design for an additional Point of Connection within eight weeks of the request under paragraph 1.2 above. Such Interconnect Design shall identify: Mercury-Nynex 11 November 1996 Page 4 of 13 Interconnect Agreement Appendix 2, Operational Procedures 113 1.5.1 the location for the Footway Box; 1.5.2 the allocation between the Parties of the costs of construction of the Point of Connection; 1.5.3 the Parties' respective Switches which are to be connected; and 1.5.4 the testing to be undertaken by the Parties in accordance with Appendix 1. 1.6 The Party requesting an additional Point of Connection shall, forthwith upon the agreement of the Interconnect Design under paragraph 1.5 above, specify the initial number of Circuits to be made available at that additional Point of Connection. Each additional Point of Connection shall have a minimum configuration of two Circuits. 1.7 The Parties shall use their respective reasonable endeavours to build and test the Interconnect Link within 15 weeks of agreeing the Interconnect Design under paragraph 1.5 above. 1.8 If the Parties have agreed to establish a new Point of Connection and either Party subsequently defaults in establishing such Point of Connection, the non-defaulting Party shall be entitled to reclaim its reasonable costs directly arising by reason of such default provided (and to the extent only) that it is not also in default in relation to the establishment of such Point of Connection. 1.9 Failure to agree the Interconnect Design under paragraph 1.5 above shall entitle either of the Parties to initiate a review pursuant to Clause 14.1.3. 2 ORDERING AND PROVISION OF CAPACITY 2.1 In respect of each existing Point of Connection, each Party shall provide Capacity Profiles to the other on or before 1 March, 1 July and 1 November in each year giving its best estimate of the contents of the Orders for Capacity likely to be placed by that Party within the twelve month period (divided into three periods: 1 April - 31 July, 1 August - 30 November, 1 December - 31 March) commencing on the date one month after such required date of provision of the Capacity Profile. Each Capacity Profile will contain at a minimum the following information: 1) the Point of Connection in question, 2) the relevant Switch in the other Party's System and 3) the amount of additional Capacity required at that Point of Connection. Mercury-Nynex 11 November 1996 Page 5 of 13 Interconnect Agreement Appendix 2, Operational Procedures 114 2.2 Within one month after the Capacity Profile is issued, the Party (for the purpose of this Part 2 of Appendix 2, the "Supplying Party") in receipt of the other's Capacity Profile shall, following discussions with the other Party (for the purpose of this Part 2 of Appendix 2, the "Ordering Party"), indicate any difficulties the Supplying Party may anticipate in satisfying the Ordering Party's Capacity Profile and shall agree with the Ordering Party in writing: 2.2.1 which part of the Capacity Profile the Supplying Party will be able to satisfy; and 2.2.2 the date by which provision may be practicable in respect of any part of the Capacity Profile which the Supplying Party will not be able to satisfy. 2.3 Notwithstanding the provisions of paragraph 2.2 above, the Supplying Party shall, if so required by the Ordering Party, maintain any existing Capacity and supply at least four additional Circuits at each Point of Connection in any four months period commencing on any of 1 April, 1 August or 1 December. 2.4 Requirements for additional Capacity during the first four month period of any Capacity Profile which the Supplying Party agrees with the Ordering Party (under paragraph 2.2.1 above) it will be able to satisfy, will comprise an ACO. 2.5 The Ordering Party shall, in respect of each ACO, place (and not subsequently cancel) Orders for additional Capacity (during the four month period covered by the ACO) amounting to not less than the amount of the Ordering Party's additional Capacity requirement specified in such ACO less two Circuits. The Supplying Party shall use all reasonable endeavours to acknowledge Orders within one Working Day of receipt of the same. 2.6 Without prejudice to paragraphs 2.3 above and 2.7 below, to the extent that additional Capacity the subject of an Order (when aggregated with the additional Capacity the subject of other Orders during the four month period covered by an ACO) exceeds the additional Capacity set out in that ACO, the Supplying Party shall use its reasonable endeavours to ensure that such excess Capacity is ready for testing as soon as is reasonably practicable. 2.7 The Supplying Party shall, in respect of Orders placed in accordance with paragraphs 2.3 and 2.5 above, comply with the following timescales: 2.7.1 where Capacity is to be made available involving the opening of a Traffic Route to a different Switch in the Supplying Party's System: 65 Working Days from date of Order to RFT Date; and Mercury-Nynex 11 November 1996 Page 6 of 13 Interconnect Agreement Appendix 2, Operational Procedures 115 2.7.2 where Capacity is to be made available involving expansion of an existing Traffic Route without opening a Traffic Route to a different Switch in the Supplying Party's System: 25 Working Days from date of Order to RFT Date. 2.8 In respect of the scenarios outlined in paragraph 2.7 above, the Parties shall use their best endeavours to ensure that the RFS Date falls within 20 Working Days of the relevant RFT Date. 2.9 In respect of additional Capacity, Capacity Charges shall be paid by the Ordering Party from the earlier of the RFS Date or (if the RFS Date has been delayed beyond 20 Working Days after the RFT Date by an act or omission of the Ordering Party) 20 Working Days after the RFT Date. 2.10 Either Party having placed an Order on the other may cancel such Order by notice in writing to the other at any time prior to the RFT Date subject to payment of the relevant Order Cancellation Charges. The Parties agree that Order Cancellation Charges are a genuine pre-estimate of the losses of the Supplying Party resulting from such cancellation, are not penalties and shall be in full and final settlement of all and any losses suffered in relation to cancellation of the Order for Capacity and that payment of Order Cancellation Charges shall be without prejudice to any liability under paragraph 2.13 below. 2.11 If the Supplying Party fails, otherwise than through the fault of the Ordering Party, to make available to the Ordering Party Capacity the subject of an Order within the relevant timescale set out in paragraph 2.7 above, then without prejudice to paragraph 2.12 below, the Ordering Party shall be entitled to receive from the Supplying Party by way of liquidated damages for delay an amount which is equal to 2% of the set up and annual rental elements of the relevant Capacity Charges for each day that the RFS Date is later than the date 20 Working Days after the RFT Date, up to a total maximum of L.2,500 per Order the subject of such delay. The Parties acknowledge that such sum constitutes a genuine pre-estimate of the Ordering Party's losses resulting from such delay, is not a penalty and shall (subject as stated in paragraph 2.12 below) be in full and final settlement of all and any losses suffered in relation to the delay. 2.12 The payment of the liquidated damages referred to in paragraph 2.11 above shall not release the Supplying Party from the obligation to deliver to the Ordering Party the Capacity ordered by the Ordering Party or from any other obligation under this Agreement. Without prejudice to its other rights and remedies, the Ordering Party may by notice in writing cancel an Order without liability to the Supplying Party provided that: Mercury-Nynex 11 November 1996 Page 7 of 13 Interconnect Agreement Appendix 2, Operational Procedures 116 2.12.1 the Supplying Party has failed to make available for testing Capacity which is the subject of the Order by the RFT Date; and 2.12.2 the notice is given prior to both the relevant RFS Date and the Parties agreeing a new RFT Date. If the Parties agree a new RFT Date, the provisions of this Part 2 of Appendix 2 shall apply in respect of such new RFT Date. 2.13 If the Ordering Party shall place Orders on the Supplying Party for less than the minimum Capacity specified at paragraph 2.5, it shall pay to the Supplying Party the set up element of the Capacity Charges in respect of the shortfall in ordered Capacity. Such payments shall be deemed to be a pre-payment in respect of further Orders placed during the subsequent 12 months. In the absence of such further Orders, such payments shall be deemed to be liquidated damages in compensation for loss suffered as a result of the Ordering Party's failure to Order the minimum Capacity and shall not be regarded as a penalty. 2.14 The Supplying Party may by service of one month`s prior written notice, in the event of an over provision of Capacity connected to any one Switch of the Ordering Party, terminate Capacity equal to the difference between the total number of Circuits connected to that Switch and 1.25 times the number of utilised Circuits. The utilised circuits are the circuits required to carry the average busy hour traffic as measured over a continuous period of six months and assessed in accordance with the traffic tables agreed between the Parties from time to time. 2.15 The Ordering Party may, within one year of the termination of a Circuit under paragraph 2.14, specify in a Capacity Profile a requirement for the terminated Circuit. In such event: 2.15.1 the Circuit shall be re-established within 25 Working Days of the Order for that Circuit; and 2.15.2 the Ordering Party shall not be required to pay a Rearrangement Charge or the set-up element of the Capacity Charge when the Circuit is re-established. 2.16 The Ordering Party may terminate the provision of a Circuit by the Supplying Party by serving not less than three months' prior written notice on the Supplying Party. 2.17 Either Party (for the purpose of this paragraph, the "First Party") can rearrange the Capacity configuration at its end of the Interconnect Link. The other Party shall, within 25 Mercury-Nynex 11 November 1996 Page 8 of 13 Interconnect Agreement Appendix 2, Operational Procedures 117 Working Days of delivery of written notification of such a rearrangement, make the necessary updates to the relevant data stored in its Switch in order for the Parties to test the rearranged configuration. If the aggregate Capacity made available to the First Party at all Points of Connection is not less than the existing Capacity together with additional Capacity specified in ACOs in respect of the period in which the Capacity rearrangement is completed, the only charges payable by the First Party shall be the Rearrangement Charges. 2.18 Additional Capacity at the established Points of Connection specified in paragraph 1.1 of Appendix 2 (which are not by way of In-Span Interconnection) may only be ordered in accordance with this Part 2 of Appendix 2 if there is sufficient available space in the relevant building. 3 ESTIMATES OF INTERNATIONAL, DIRECTORY ENQUIRY AND OPERATOR ASSISTANCE CALLS 3.1 NYNEX shall provide to Mercury, on or before each 1 March, 1 June, 1 September and 1 December, estimates of the total traffic for the next year (specifying total minutes, number of calls and seven day profile) which it could convey to Mercury in respect of International Calls and International ISDN Calls to each of the 25 countries with the highest volumes of Calls originating on the NYNEX System. 3.2 As a condition of Mercury providing to NYNEX any or all of the Telecommunication Services listed in Tables 8, 9, 10, 11 and 12 of Schedule 3, NYNEX shall provide to Mercury on or before 1 March in each year, an estimate of its total traffic for the subsequent twelve months in respect of such Telecommunication Services (whether to be provided by Mercury or not). Mercury-Nynex 11 November 1996 Page 9 of 13 Interconnect Agreement Appendix 2, Operational Procedures 118 4 FORECASTING OF NATIONAL AND EMERGENCY CALLS 4.1 Each Party shall provide to the other, on or before 1 March and 1 September in each year, a written forecast of its traffic at each Point of Connection during the following two years, broken down according to each three month period (for the purposes of this Appendix 2, a "Quarter"). Such forecast shall, in respect of each Traffic Route, specify the weekday total traffic, weekday busy hour traffic (for both am and pm) in erlangs and weekday busy hour call attempts in respect of each of the Telecommunication Services (other than those specified in paragraphs 3, 6, 8, 9, 10, 11 and 12 of Schedule 2). 4.2 If, during a period of one month, the traffic conveyed by one Party (for the purposes of this Appendix 2, the "Conveying Party") to the other differs in any material respect from that specified in the Conveying Party's forecast for that period, the other Party may request a revised forecast for the remaining portion of the period covered by the forecast. Such forecast shall be provided by the Conveying Party within one month of such request. 4.3 If, following the provision of a revised forecast under paragraph 4.2 above, the traffic conveyed by the Conveying Party to the other during a period of one month differs in any material respect from that specified in the Conveying Party's forecast for that period, the other Party's obligations under Clause 4.1 shall be modified so that it is only obliged to use its reasonable endeavours to provide the Telecommunication Service in question for the remaining portion of the first six month period covered by the revised forecast. 4.4 The Conveying Party's obligations under Clauses 4.1.1 and 4.1.3 respectively shall be modified so that it is only obliged to use its reasonable endeavours thereunder in respect of a material change in the forecast traffic for any Quarter unless such material change has been specified for such Quarter in two consecutive forecasts provided under paragraph 4.1 above (in which case such modification shall cease to apply for such Quarter). In the event that either Party forecasts a material change in traffic under paragraph 4.1 above, the other Party may, within 30 days of receipt of that forecast, initiate a review of its own relevant charges in accordance with Clause 14.1.3. Any modification to such charges resulting from such review shall be effective from the beginning of the second Quarter commencing after the date of the relevant Review Notice. 4.5 Without prejudice to paragraphs 4.2, 4.3, 4.4 and 4.5 above, each Party shall give the other as much notice as is reasonably practicable of material changes in traffic volumes. 4.6 For the purposes of paragraphs 4.3 and 4.4 of this Part 4 of Appendix 2, traffic conveyed by one Party shall only be deemed to differ in a material respect from that Party's Mercury-Nynex 11 November 1996 Page 10 of 13 Interconnect Agreement Appendix 2, Operational Procedures 119 forecast for a period if the volume of traffic conveyed materially exceeds the volume which was forecast or if the profile of traffic conveyed materially differs from the profile which was forecast. 4.7 As a condition of Mercury providing to NYNEX the Telecommunication Service listed in paragraph 13 of Schedule 2, NYNEX shall provide to Mercury: 4.7.1 on or before 1 March in each year, a forecast of its total traffic for the subsequent twelve months in respect of such Telecommunication Service (whether to be provided by Mercury or not); and 4.7.2 during the first week of each calendar month, a forecast of the actual traffic which NYNEX anticipates conveying to Mercury in respect of such Telecommunication Services during the immediately following calendar month. 4.8 The information to be provided by NYNEX to Mercury in respect of forecasts in accordance with paragraph 4.8 shall compromise the following: 4.8.1 number of call attempts during busiest hour of estimate period; 4.8.2 total call minutes during busiest hour of estimate period; 4.8.3 cumulative calls for the estimate period; 4.8.4 cumulative call minutes for the estimate period; 4.8.5 24 hour time of day profile for weekdays; and 4.8.6 average call duration. 4.9 NYNEX shall provide to Mercury such prior notification as is reasonably possible of any anticipated increase or decrease of 10% or more of the current level of traffic estimated under paragraph 3.1.2 above (whether due to planned marketing campaigns or any other reason). 5 ALTERATIONS TO THE SYSTEMS 5.1 Neither Party shall make or permit to be made any alteration, adjustment or addition to its System (which for the purpose of this paragraph 5 includes each Point of Connection) or to any of its plant equipment or apparatus used in connection therewith in such a way as materially to impair the operation of the System of the other Party or otherwise materially to affect the provision of the Telecommunication Services pursuant to this Agreement. Without prejudice to paragraph 5.2 below, if any such alteration, adjustment or addition is necessarily to be made by Mercury-Nynex 11 November 1996 Page 11 of 13 Interconnect Agreement Appendix 2, Operational Procedures 120 a Party, it shall use its reasonable endeavours to minimise the impact on the other Party of such alteration, adjustment or addition and shall give the other as much notice thereof as is reasonably practicable in all the circumstances. 5.2 Each Party (for the purposes of this paragraph 5, the "Altering Party") shall give notice to the other Party in writing of any proposals for alterations, adjustments or additions to its System which the Altering Party might reasonably anticipate (from the facts known to it) would or might when made have the effect of requiring the other Party materially to modify or replace any part of that other Party's System. Such information shall be given by whichever is the earlier of (a) the date being seven months prior to the date of such change and (b) the date on which the Altering Party is obliged to inform the other in accordance with its Licence. 5.3 The Altering Party shall, on the request of the other, consult with the other Party and provide all reasonable co-operation and assistance to facilitate the introduction of any proposed modification or replacement referred to in paragraph 5.2 above. Such other Party shall notify the Altering Party of the nature and costs of such modification or replacement as soon as reasonably practicable, after receipt of the Altering Party's notice paragraph 5.2, and shall use reasonable endeavours to minimise such costs. 5.4 The Altering Party shall bear the costs of any alterations, adjustments or additions to its System and the reasonable costs incurred by the other Party by reason of any such modification or replacement referred to in paragraph 5.2 above, except that each Party shall pay its own costs arising out of an alteration, adjustment or addition where: 5.4.1 the Parties agree in writing to alter, adjust or add to their respective Systems for their mutual benefit; 5.4.2 the alteration, adjustment or addition by the Altering Party is directed or is the result of a determination made by the Director (otherwise than by reason of a breach by the Altering Party of any condition of its Licence); or 5.4.3 the alteration is a global revision of the Generic C7 Signalling Interface Specification in compliance with the then current international signalling standards.

Mercury-Nynex 11 November 1996 Page 2 of 7 Interconnect Agreement Appendix 3, Billing Procedures 124 5.5 charges for set up and training in respect of Mercury's emergency service in advance of Mercury commencing the provision of that service; and 5.6 charges for the manual entry of COSAR data within 30 days of the end of the Billing Period in which they accrue. 6 Each invoice submitted by the Billing Party shall be delivered to the Paying Party by first-class post or facsimile transmission and shall contain the following information: - invoice date; - Billing Period; - billed amounts broken down into standard, exempt and zero; VATable amounts; - VAT amounts per invoice for standard amounts only; - VAT registration number and company number; - VAT rates used; - total amount payable; and - due date for payment. 7 The Billing Party shall provide, at the same time as it delivers an invoice to the Paying Party, a summary statement relating to such invoice containing the following information (by Point of Connection with an aggregate figure for all Points of Connection) split between charge periods for each of the Telecommunication Services: - number of Calls; - total duration of Calls (in hours, minutes and seconds); and - total revenue. 8 The Billing Party shall maintain and retain for a period of three years from its submission of each invoice true and accurate books of account and such information (contained in or on discs, tapes, documents or other records) as may reasonably be required for calculation or verification of the amounts payable under such invoice. 9 Charges for the conveyance of Calls shall accrue only when: 9.1 the Call is conveyed by the Mercury System to the NYNEX System or vice versa and connection is made to the called Customer's System (whether or not via a Third Party Operator's System or an Authorised Mercury-Nynex 11 November 1996 Page 3 of 7 Interconnect Agreement Appendix 3, Billing Procedures 125 Overseas System) and the Called Customer Answer Signal is received by the System on which the Call originated; or 9.2 the Call cannot be conveyed in accordance with paragraph 9.1 and as a consequence is diverted to a service or system in accordance with arrangements previously agreed with the called Customer; or 9.3 as otherwise agreed in writing by the Parties from time to time. 10 Charging will cease on the earlier of the detection of the calling or called Customer's release signal. This release signal will be generated: 10.1 by the Operator of the System of the calling Customer immediately after the calling Customer has cleared the connection; or 10.2 in the case of the Operator of the System of the called Customer, immediately after the called Customer held time-out (that is the period of time between the called Customer clearing the connection and the connection being released as agreed between the Parties); 11 Charges for the conveyance of Calls shown in Part 2 of Schedule 3 are expressed either per minute (when Call duration is measured in minutes and seconds) or as a charge per Call. 12 The charge for conveyance of a Call is calculated by the following formula: D = (AxB) + C Where: A = the Call duration in minutes rounded to the nearest 0.1 second B = the relevant pence per minute charge specified in Schedule 3 C = the relevant pence per call charge specified in Schedule 3 D = the charge rounded to the nearest 0.1 pence. 12.1 Where the duration of the Call extends across more than one time band, the total charge will be comprised of the sum of the duration of the components multiplied by the rates relevant to each individual time band. Mercury-Nynex 11 November 1996 Page 4 of 7 Interconnect Agreement Appendix 3, Billing Procedures 126 12.2 Where it is impracticable for Mercury and NYNEX to record such information as is necessary to raise an invoice, Mercury and NYNEX shall agree the appropriate charge. 13 Subject to paragraph 17 below, all charges invoiced under this Agreement shall be payable within 30 days of the date of issue of the invoice requiring payment thereof. 14 The Billing Party shall be entitled to charge and receive interest in respect of any amount due or deemed to be payable hereunder, which shall be the subject of a separate invoice containing the information set out in paragraph 15, at the rate of 2% above the one month London Inter-Bank Offered Rate from the later of the two dates specified below until the date of payment in full, whether before or after any judgement: 14.1 the day following the end of the 30 day period referred to in paragraph 13 above; or 14.2 the day following the end of a period of not less than seven days after service of written notice that the Billing Party intends to claim interest on the overdue sum. Any such interest shall accrue day by day and shall be compounded monthly. 15 Each invoice claiming interest shall contain the following information: - invoice date; - date and number of original invoice on which interest is being charged; - start date and end date for interest period being invoiced; - interest rate applied; and - interest charged. 15.1 If either Party disputes the amount of any invoice (for the purpose of this paragraph 15 a "Disputed Invoice") delivered by the other Party under this Agreement that Party (for the purpose of this paragraph 15, "the Disputing Party") shall use its reasonable endeavours to issue a notice in writing setting out its objection to the Disputed Invoice and containing the following information within 30 days of receipt of the Disputed Invoice: - date and number of disputed invoice; - amount in dispute; - reason for dispute; and Mercury-Nynex 11 November 1996 Page 5 of 7 Interconnect Agreement Appendix 3, Billing Procedures 127 - supporting documentation as appropriate. In any event such notice shall be issued within 12 months of the delivery of the Disputed Invoice, failing which it shall be of no effect. The dispute may thereafter be referred forthwith by either Party (having given prior written notice to the other to such effect) for investigation and determination by such Person (being chartered accountants) as the Parties may agree, or in default of agreement, as may be nominated by the President of the Institute of Chartered Accountants in England and Wales at that time to act as an expert and not as an arbitrator and whose decision, in the absence of evidence of manifest error, shall be final and binding. The Parties shall co-operate in such investigation. 15.2 Subject as provided in paragraph 17 below any sum thus found after such determination or settlement between the Parties to be due shall be promptly paid (including any interest payable pursuant to paragraph 14 above on any part of such sum deemed payable in full under paragraph 17 below), within 30 days of the date of such determination or settlement between the Parties. 15.3 Any sum found after such determination or settlement between the Parties to be overpaid (including any interest payable or paid pursuant to paragraph 14 above) shall be deducted from the first invoice rendered by the Party so overpaid after either the date of such determination or settlement between the Parties or repaid to the other party if no subsequent invoices are rendered within 30 days of such determination or settlement. 15.4 The costs of such expert shall be paid by the Disputing Party unless the Disputed Invoice is established by the expert to have been incorrect by greater than a 5% margin in which case the Party delivering the Disputed Invoice shall pay such costs. 16 Notwithstanding the reference of any dispute for investigation and determination under paragraph 15 above, if the amount in dispute represents less than five percent of the total amount (excluding VAT) of the Disputed Invoice, the invoiced amount shall, for the purposes of paragraph 13 above be deemed payable in full. If the amount in dispute represents five percent or more of the total amount (excluding VAT) of the Disputed Invoice such disputed amount shall, for the purposes of paragraph 13 above be deemed not payable pending issue of the expert's decision as aforesaid and, for the avoidance of doubt, any undisputed balance shall be payable in full. 17 All charges specified in Schedule 3 are exclusive of value added tax which shall be paid at the rate and in the manner prescribed by law from time to time. Mercury-Nynex 11 November 1996 Page 6 of 7 Interconnect Agreement Appendix 3, Billing Procedures 128 18 If the Billing Party cannot record Calls for the purpose of preparing invoices, then the Paying Party shall, if practicable, do so until such time as the Billing Party can record Calls as aforesaid subject to the Billing Party meeting the Paying Party's reasonable costs incurred in connection therewith.
