NUCLEAR INSTALLATIONS 5.1 Save as provided in Sub-Clause 5.2 below notwithstanding anything to the contrary contained in this Agreement (but subject to the following provision), in circumstances affecting a generator or nuclear electricity (a "Nuclear Generator") in which: (a) a breach of any of the matters specified in Sub-Clause 5.4 below may be reasonably anticipated; and (b) there is no defense (other than that provided for under this Sub-Clause) available to the Nuclear Generator in respect of the breach referred to in Sub-Clause 5.1(a); the Nuclear Generator shall be entitled to take any acting or refrain from taking any action which is reasonably necessary in order to avert the breach referred to in Sub-Clause 5.1(a) and each and every provision of this Agreement shall be read and construed subject to this Clause, Provided that the Nuclear Generator shall: (i) make reasonable efforts to verify the factors that it takes into account in its assessment of the circumstances and anticipated breach referred to above; and (ii) use its best endeavors to comply with the relevant provision in a manner which will not cause the Nuclear Generator to breach any of the matters specified in Sub-Clause 5.4 below. 5.2 Sub-Clauses 5.1 and 5.3 shall not apply in relation to the provisions of SDC1, SDC2 and SDC3 of the Grid Code which will apply with full force and effect notwithstanding the occurrence of the circumstances referred to in Sub-Clause 5.1(a) (including those provisions specified in Sub-Clause 5.4 which relate to Safety of Personnel and Plant). 5.3 Save as provided in Sub-Clause 5.2 above notwithstanding anything this Agreement, the Nuclear Generator shall be entitled upon giving reasonable notice 8 to all affected Parties to require any Party to take any reasonable and proper action whatsoever to the extent necessary in order to comply with (or avert an anticipated breach of) any of the matters specified in Sub-Clause 5.4 below. 5.4 The matters referred to in Sub-Clauses 5.1 and 5.3 above are any covenant, agreement, restriction, stipulation, instruction, provision, condition or notice contained, or referred to, in a licence for the time being in force, granted in accordance with the Notice Installation Act 1965 (or legislation amending, replacing or modifying the same) or any consent, or approval issued, or to take effect from time to time under such licence, any emergency arrangements, operating rules or other matters from time to time, under such licence, any emergency arrangements, operating rules or other matters from time to time approved by the relevant authority under, or pursuant to, any such agreements, restrictions, stipulations, instructions, provisions, conditions or notices. 5.5 The Nuclear Generator shall indemnify and keep indemnified any Party for any loss, damage, costs and expenses incurred by that Party as a consequence of any action of that Party pursuant to Sub-Clause 5.3 (to the extent that the action was not required by any licence or agreement binding on that Party). 5.6 Notwithstanding the fact that any action or inaction allowed by Clause 5.1 above does not constitute a breach of this Agreement or an Event of Default under Clause 17 below, the Nuclear Generator shall be liable to the other Parties to this Agreement for any loss, claims, costs, liabilities and expenses arising from such action or inaction to the extent only that such loss, claims, costs, liabilities and expenses (had it arisen as a result of a breach of this Agreement) would not have been limited or excluded under the provisions of Clause 15 below. 9 6. PRINCIPLES OF OWNERSHIP 6.1 Ownership - electrical boundaries Subject to the Transfer Scheme or any contrary agreement in this Agreement, any Supplemental Agreement or elsewhere the division of ownership of Plant and Apparatus shall be at the electrical boundary, such boundary to be determined in accordance with the following principles: (i) In relation to Plant and Apparatus located between the NGC Transmission System and a Power Station, the electrical boundary is at the busbar clamp on the busbar side of the busbar isolators on Generators and Power Station transformer circuits; (ii) save as specified in Clause 6.1(iii) below, in relation to Plant and Apparatus located between the NGC Transmission System and a Distribution System, the electrical boundary is at the busbar clamp in the busbar side of the Distribution System voltage busbar selector isolator(s) of the NGC Transmission System circuit or, if a conventional busbar does not exist, an equivalent isolator. If no isolator exists an agreed bolted connection at or adjacent to the tee point shall be deemed to be an isolator for these purposes; (iii) in relation to Plant and Apparatus located between the NGC Transmission System and a Distribution System and owned by NGC but designed for a voltage of 132KV or below, the electrical boundary is at the busbar clamp on the busbar side of the busbar selector isolator on the Distribution System circuit or, if a conventional busbar does not exist, an equivalent isolator. If no isolator exists, an agreed bolted connection at or adjacent to the tee point shall be deemed to be an isolator for these purposes; and (iv) in the case of a metal clad switchgear bay the electrical boundary will be the equivalent of those specified in this Clause 6.1 save that: 10 (a) for rack out switchgear, the electrical boundary will be at the busbar shutters; (b) for SF6 switchgear, the electrical boundary will be at the gas zone separators on the busbar side of the busbar selection devices. 6.2 If a User wants to use transformers of specialised design for unusual load characteristics at the electrical boundary, NGC shall own such transformers but the User shall pay NGC for the proper and reasonable additional cost thereof as identified by NGC in the Offer covering such transformers. In this Sub-Clause 6.2 "unusual load characteristics" means loads which have characteristics which are significantly different from those of the normal range of domestic, commercial and industrial loads (including loads which vary considerably in duration or magnitude). 6.3 For the avoidance of doubt nothing in this Clause 6 shall effect any transfer of ownership in any Plant or Apparatus. 7. METERING 7.1 Each User consents to NGC having access to and copies of all meter readings taken from Energy Metering Equipment pursuant to the Pooling and Settlement Agreement in any Financial Year for the purposes of calculating Connection Charges and Use of System Charges due from Users or for the purpose of operating the NGC Transmission System. Such access and copies shall be obtained from the Settlement System Administrator appointed under the Pooling and Settlement Agreement from time to time provided always that if the Settlement System Administrator fails to provide such access and copies at NGC's request the User shall supply any such meter readings in the possession of the User direct to NGC. 11 7.2 The relationship between the Parties hereto with respect to Energy Metering Equipment shall be regulated by Part XV of the Pooling and Settlement Agreement. 7.3 In respect of Operational Metering Equipment owned by the Party and in respect of which access and rights to deal with such Operational Metering Equipment are not set down in any other document the Parties shall grant each other such access and the rights as are reasonably necessary to enable them to perform their obligations under this Agreement and the Grid Code upon presentation of a suitable indemnity and the Parties shall take such action as may be necessary to regularise the position forthwith thereafter. 8. NGC OBLIGATIONS 8.1 NGC agrees with each User to make available, plan, develop, operate and maintain the NGC Transmission System in accordance with the NGC Transmission Licence and with the Grid Code subject to any Derogations from time to time. 9. COMPLIANCE WITH THE GRID CODE/DISTRIBUTION CODE 9.1 Subject to Sub-Clause 9.3 each Party agrees with each other Party to be bound by and to comply in all respects with the provisions of the Grid Code in so far as applicable to that Party. 9.2 Subject to Sub-Clause 9.3 each Party agrees with each other Party to be bound by and to comply in all respects with the provisions of the relevant Distribution Code(s) in so far as applicable to that Party except as may be otherwise provided in any agreement for connection to a Distribution System. 9.3 Neither NGC nor a User need comply with the Grid Code or any relevant Distribution Code(s) to the extent (if any) that: 12 (i) either the Director has issued directions relieving NGC or that User from the obligation under its respective licence to comply with the Licence Standards, the Grid code or any relevant Distribution Code(s) in respect of such parts of the Grid Code or any relevant Distribution Code(s) respectively as may be specified in those directions or to the extent that NGC and a User which does not have a Licence under the Act can and have so agreed in any Supplemental Agreement in relation to any Connection Site or New Connection Site and/or Derogated Plant; or (ii) (in the case of a User) the Grid Code relates to the provision by that User of any Ancillary Services unless there is an Ancillary Services Agreement in force between that User and NGC for the payment by NGC for such Ancillary Services; or (iii) (in the case of NGC) the Grid Code imposes any obligation on NGC to make available Additional Scheduling Data (as defined in the Grid code) before 31st December 1990. 9.4 In this Sub-Clause 9.4 the following expressions shall bear the following meanings: "Required Standard" In relation to an item of Derogated Plant, the respective standard required of that item (which shall not exceed that required by the Grid code or the Licence Standards, as the case may be) as specified in or pursuant to the relevant Derogation; "Back Stop Date" in relation to an item of Derogated Plant, the date by which it is to attain its Required Standard, as specified in or pursuant to the relevant Derogation. 13 Each User undertakes to NGC and NGC undertakes to each User to use all reasonable endeavours to carry out such works as are necessary to ensure that each item of Derogated Plant owned or operated by that User or NGC (as appropriate) is brought up to the Required Standard applicable to it no later than the Back stop Date applicable to it. 9.5 The terms and provisions of the Fuel Security Code shall prevail to the extent that they are inconsistent with the Grid code or any Distribution code and the Parties' obligations under this Agreement shall be construed accordingly. 10. MODIFICATIONS 10.1 No modification may be made by or on behalf of a User or NGC otherwise than in accordance with the provisions of this Clause 10. 10.2 Modifications Proposed by Users 10.2.1. If a User wishes to make a Modification it shall complete and submit to NGC a Modification Application and comply with the terms thereof. 10.2.2. NGC shall make the Modification Offer to that User as soon as practicable and (save where the Director consents to a longer period) any event not more than 3 months after receipt by NGC of the Modification Application. The Modification Offer shall include details of any variation NGC proposes to make to the Supplemental Agreement which applies to the Connection Site in question. During such period NGC and the User concerned shall discuss in good faith the implications of the proposed Modifications. 10.2.3.

Once a Modification Application has been made by a User pursuant to Sub-Clause 10.3.2 the provisions of Sub-Clauses 10.2.2, 10,2.3 and 10.2.4 shall thereafter apply. 11. NEW CONNECTION SITES 11.1 If a User wishes to connect a New Connection Site it shall complete and submit to NGC a Connection Application and comply with the terms thereof. 11.2 Without prejudice to Condition 10B4 of the NGC Transmission Licence NGC shall make a Connection Offer to that User as soon as practicable after receipt of the Connection Application and (save where the Director consents to a longer period) in any event not more than 3 months after receipt by NGC of the Connection Application. 11.3 The Connection Offer shall remain open for acceptance for 3 months from its receipt by that User unless either that User or NGC makes an application to the Director under Condition 10C of the NGC Transmission Licence, in which event the Connection Offer shall remain open for acceptance until the date 14 days after any determination by the Director pursuant to such application. 11.4 If the Connection Offer is accepted by that User the connection shall proceed according to the terms of the Supplemental Agreement entered into consequent upon acceptance of the Offer. 12. GENERAL PROVISIONS CONCERNING MODIFICATIONS AND NEW CONNECTION SITES 12.1 subject to the payment of its Reasonable Charges, if any, as provided for in this Sub-Clause NGC undertakes to each User to provide all advice and assistance reasonably requested by that User to enable that User adequately to assess the 16 implications (including the feasibility) of making a Modification to the User's Equipment or the Users System (whether such Modification is to be made at the request of NGC or of the User) or of constructing a New Connection Site (including adequately assessing the feasibility of making any Connection Application or considering the terms of any Connection Offer). If the proposed Modification by the User is or may be required as a result of a Modification proposed by NGC then NGC shall provide such advice and assistance free of charge. If the proposed Modification is or may be proposed by the User or if the advice and assistance is in respect of a New connection Site NGC may charge the User Reasonable charges for such advice and assistance. The provisions of such advice and assistance shall be subject to any confidentiality obligations binding on NGC and that User. 12.2 When giving such advice and assistance NGC shall comply with Good Industry Practice. 12.3 NGC shall have no obligation to compensate any User (the "First User") for the cost or expense of any Modification required to be made by any User as a result of any NGC Modification under Sub-Clause 10.3.1. Where such NGC Modification is made as a result of the construction of a New Connection Site or a Modification for another User (the "Other User"), the Other User shall compensate the First User for the reasonable and proper cost and expense of any Modifications required to be made by the First User as a result of that NGC Modification. Such compensation shall be paid to the First User by the Other User within thirty days of production to the Other User of a receipted invoice (together with a detailed breakdown of such reasonable costs and expenses) for the expenditure which has been incurred by the First User. 17 12.4 Modification Offers and Connection Offers conditional Upon other Modification Offers and Connection Offers If at the time of making any Offer or Modification Offer or Connection Offer to a User ("the Second Offer") there is an outstanding Modification Offer(s) or Connection Offer(s) to another User(s) ("the First Offer") which if accepted would affect the terms of the Second Offer NGC shall at the time of making the Second Offer. (i) inform the recipient(s) of both the First Offer(s) and Second Offer(s) in writing that there is another Offer outstanding which might affect them; and (ii) be entitled to make the First Offer(s) and Second Offer(s) conditional upon other outstanding Offers not having been or being accepted; and (iii) be entitled to vary the terms of either Offer if the other Offer is accepted first on the same procedures as those set out in Clauses 10.2.2 to 10.2.4 or 11.2 to 11.4 inclusive as the case may be. 13. ADDITIONAL PARTIES 13.1 The Parties shall admit as an additional party to this Master Agreement any person who accepts a Connection Offer from NGC or any new Embedded User (the "New Party") and who is not at the time already a Party. Such admission shall take effect by way of Accession Agreement prepared by NGC at the expense and cost of the New Party and to be executed by NGC for itself and on behalf of all other Parties. Upon execution of the Accession Agreement by NGC and the New Party and subject to the terms and conditions of that Accession Agreement, the New Party shall become a Party for all purposes of this Agreement. 18 13.2 Each Party hereby authorises and instructs NGC to sign any such Accession Agreement on its behalf and undertakes not to withdraw, qualify or revoke any such authority or instruction at any time. 13.3 NGC shall promptly notify all Parties in writing that the New Party has become a Party. 14.

Accordingly, (a) each User and NGC undertake to discuss in good faith the correct identification of the details of each part of Appendix F of each Supplemental Agreement entered into between NGC and the User with a view to amending the same as necessary to reflect the correct position. To the extent that agreement on the correct position cannot be reached within 12 months after the date of that Supplemental Agreement the matter shall be referred to arbitration for determination in accordance with Clause 26 of this Agreement and such details shall be amended accordingly following such agreement or determination (as the case may be); and (b) in relation to Appendix A of each Supplemental Agreement, NGC undertakes to establish a new asset register, specifying all Plant and Apparatus owned by NGC which is necessary to connect each User's Equipment to the NGC Transmission System at each Connection Site, during the course of the Financial Year ending 31st March 1991 in accordance with paragraph 2.2 of Appendix E to such Supplemental Agreement.
