(c) Any Interest period which would otherwise end during the week preceding, or extend beyond the Repayment Date shall be of such duration that it shall end on the Repayment Date. 8.2 Selection (a) The Borrower may select an Interest Period for a Loan in either the relevant Request or, if (in the case of a Facility A Loan) the Loan has been borrowed, a notice received by the Bank not later than 4.00 p.m. on the Business Day before the commencement of that Interest Period. - -------------------------------------------------------------------------------- 18 - -------------------------------------------------------------------------------- Each Interest Period for a Loan will commence on its Drawdown Date or (in the case of a Facility A Loan) the expiry of its preceding Interest Period. (b) Subject to the following provisions of this Clause 8, each Interest Period will be either an approved duration or an optional duration as so selected under paragraph (a) above. In this Clause 8:- "approved duration" means 1 or 2 weeks or 1, 2, 3 or 6 months; and "optional duration" means any other period agreed by the Bank. (c) If the Borrower fails to select an Interest Period for an outstanding Facility A Loan in accordance with paragraph (a) above, that Interest Period will, subject to the other provisions of this Clause 8, be one month. (d) No Interest Period for a Facility B Loan may extend beyond the Repayment Date. 8.3 Selection of an optional duration (a) If the Borrower selects an Interest Period of an optional duration, it may also select an Interest Period of an approved duration to apply if the selection of an optional duration becomes ineffective in accordance with paragraph (b) below. (b) If:- (i) the Borrower requests an Interest Period of an optional duration; and (ii) the Bank notifies the Borrower not later than 10.30 a.m. on the first Business Day of that Interest Period that matching deposits are not available to it in the London interbank market to fund the Loan for that Interest Period, the Interest Period for that Loan shall be the alternative period so specified or, in the absence of any alternative selection, one month. 8.4 Non-Business Days If an Interest Period would otherwise end on a day which is not a Business Day, that Interest Period shall instead end on the next Business Day in that calendar month (if there is one) or the preceding Business Day (if there is not). 8.5 Consolidation and splitting (a) Notwithstanding Clause 8.2 (Selection), the first Interest Period for each Facility A Loan shall end on the same day as the current Interest Period for any other Facility A Loan. On the last day of those Interest Periods, those Loans shall be consolidated and treated as one Loan. (b) The Borrower may, subject to Clause 2(b), in any notice selecting an Interest Period for an outstanding Facility A Loan under Clause 8.2 (Selection), direct that the Facility A Loan in question shall, at the beginning of that Interest Period be divided into (and thereafter be treated for all purposes under this Agreement as) two Facility A Loans in such amount each - -------------------------------------------------------------------------------- 19 - -------------------------------------------------------------------------------- being a minimum of (pound)25,000,000 and an integral multiple of (pound)1,000,000 as the Borrower shall specify and on the first day of the Interest Period to which that notice relates those Facility A Loans shall be so divided. 8.6 Other adjustments The Bank and the Borrower may enter into such other arrangements as they may agree for the adjustment of Interest Periods and the consolidation and/or splitting of Loans. 9. INTEREST 9.1 Interest rate The rate of interest on each Loan for each of its Interest Periods is the rate per annum determined by the Bank to be the aggregate of the applicable:- (a) Margin; (b) LIBOR; and (c) MLA Cost. 9.2 Due dates Except as otherwise provided in this Agreement, accrued interest on each Loan is payable by the Borrower on the last day of each Interest Period for that Loan and also, if the Interest Period is longer than 6 months, on the date falling 6 months after the first day of that Interest Period. 9.3 Default interest (a) If the Borrower fails to pay any amount payable by it under this Agreement, it shall forthwith on demand by the Bank pay interest on the overdue amount from the due date up to the date of actual payment, as well after as before judgment, at a rate (the "default rate") determined by the Bank to be 1 per cent. per annum above the rate which would have been payable if the overdue amount had, during the period of non-payment, constituted a Loan in the currency of the overdue amount for such successive Interest Periods of such duration as the Bank may determine (each a "Designated Interest Period"). (b) The default rate will be determined by the Bank on each Business Day or the first day of, or two Business Days before the first day of, the relevant Designated Interest Period, as appropriate. (c) If deposits in the currency of the overdue amount are not at the relevant time being made available by the Bank to leading banks in the London interbank market, the default rate will be determined by reference to the cost of funds to the Bank from whatever sources it may select. (d) Default interest will be compounded at the end of each Designated Interest Period. - -------------------------------------------------------------------------------- 20 - -------------------------------------------------------------------------------- 10. PAYMENTS 10.1 Place All payments under this Agreement shall be made to the relevant Party to its account at such office or bank in the U.K. as it may notify to the other Party for this purpose. 10.2 Funds Payments under this Agreement shall be made for value on the due date at such times and in such funds as the Bank may specify as being customary at the time for the settlement of transactions in sterling. 10.3 Currency (a) Amounts payable in respect of costs, expenses and taxes and the like are payable in the currency in which they are incurred. (b) Any other amount payable under this Agreement is, except as otherwise provided in this Agreement, payable in sterling. 10.4 Set-off and counterclaim All payments made by the Borrower under this Agreement shall be made without set-off or counterclaim. 10.5 Non-Business Days (a) If a payment under this Agreement is due on a day which is not a Business Day, the due date for that payment shall instead be the next Business Day in the same calendar month (if there is one) or the preceding Business Day (if there is not). (b) During any extension of the due date for payment of any principal under this Agreement interest is payable on that principal at the rate payable on the original due date. 11. TAXES 11.1 Gross-up Subject to Clause 11.4 (Exceptions from gross-up), each payment to be made by the Borrower under this Agreement shall be made free and clear of and without deduction or withholding (whether for or on account of tax or otherwise) unless the Borrower is required by law to make such a payment subject to such deduction or withholding in respect of any taxes imposed by laws of the United Kingdom or any federation or association of sovereign states of which the United Kingdom is a member, in which case the sum payable by the Borrower in respect of which such deduction or withholding is required to be made shall (subject as provided in this Clause) be increased to the extent necessary to ensure that, after the making of such deduction or withholding, the Bank receives and retains (free from any liability in respect of any such deduction or withholding) a net sum equal to the sum which it would have received and so retained had no such deduction or withholding been made or required to be made. - -------------------------------------------------------------------------------- 21 - -------------------------------------------------------------------------------- 11.2 Tax receipts Within 30 days after paying any sum from which it is required by law to make any deduction or withholding, the Borrower shall deliver to the Bank evidence satisfactory to the Bank of that deduction, withholding or payment and (where remittance is required) of the remittance thereof to the relevant taxing or other authority (a receipt by the relevant taxing or other authority being deemed to be such evidence). 11.3 Tax credits If the Borrower makes a payment under Clause 11.1 (Gross-up) for the account of the Bank and the Bank determines that it has received or been granted a credit against or relief or remission for, or repayment of, any tax paid or payable by it in respect of or calculated with reference to the deduction or withholding under Clause 11.1 (Gross-up) the Bank shall, to the extent that it can do so without prejudice to the retention of the amount of such credit, relief, remission or repayment, pay to the Borrower such amount as the Bank determines is attributable to such deduction or withholding under Clause 11.1 (Gross-up) and which will leave the Bank (after such payment) in no better or worse position than it would have been in if the Borrower had not been required to make such deduction or withholding under Clause 11.1 (Gross-up). Nothing in this Clause 11.3 shall interfere with the right of the Bank to arrange its tax affairs in whatever manner it thinks fit nor oblige the Bank to disclose any information relating to its tax affairs or any computations in respect thereof. 11.4 Exceptions from gross-up (a) If: (i) the Bank is not or ceases to be a Qualifying Bank; and (ii) as a result the Borrower is required to deduct or withhold United Kingdom income tax in respect of payments of interest to be made by the Borrower to the Bank under this Agreement, then the Borrower shall not be liable to pay under Clause 11.1 (Gross-up) in respect of any such payment of interest any amount in excess of the amount it would have been obliged to pay if the Bank were a Qualifying Bank provided that this Clause 11.4 shall not apply if, after the date of this Agreement any change occurs in, or in the official interpretation or application of, any relevant law or the practice of the United Kingdom Inland Revenue and as a result thereof the Bank is not or ceases to be a Qualifying Bank. (b) The obligation of the Borrower to pay an additional amount under Clause 11.1 (Gross-up) shall not apply to the extent that the tax deducted is tax on the overall net income of the Bank save to the extent that such tax is in respect of the relevant payment from which the deduction must be made. 11.5 Notification If at any time after the date of this Agreement the Bank is aware that it is not or will cease to be a Qualifying Bank (for whatever reason), it shall promptly notify the Borrower. - -------------------------------------------------------------------------------- 22 - -------------------------------------------------------------------------------- 12. MARKET DISRUPTION 12.1 Market disruption If, by reason of circumstances affecting the London interbank market generally, the Bank is unable to make any determination of LIBOR, the Bank shall promptly notify the Borrower of the fact and that this Clause 12 (Market disruption) is in operation. 12.2 Alternative basis (a) If a notification under Clause 12.1 (Market disruption) applies to a Loan which has not been made: (i) that Loan shall still be made; (ii) the first Interest Period of that Loan shall be one month; and (iii) interest in respect of that Loan shall be calculated in accordance with paragraph (b) below. (b) If a notification under Clause 12.1 (Market disruption) applies to a Loan then, notwithstanding any other provision of this Agreement: (i) within 5 Business Days of receipt of the notification, the Borrower and the Bank shall enter into negotiations for a period of not more than 30 days with a view to agreeing an alternative basis for determining the rate of interest and/or funding applicable to that Loan and/or any other Loans; (ii) if no alternative basis is agreed, the Bank shall certify on or before the last day of the Interest Period to which the notification relates an alternative basis for maintaining that Loan, which shall be binding on the Borrower; and (iii) any such alternative basis may include an alternative method of fixing the interest rate, alternative Interest Periods or alternative currencies but it must reflect the cost to the Bank of funding the Loan from whatever sources it may select plus the Margin plus any MLA Cost. (c) The Bank shall consult with the Borrower at least once every 14 days after the occurrence and during the continuance of the circumstances specified in the foregoing provisions of this Clause 12 with a view to reverting to the normal provisions for the determination of the rates of interest applicable to any Loan under this Agreement. 13. INCREASED COSTS 13.1 Increased costs (a) Subject to Clause 13.2 (Exceptions), the Borrower shall within 5 Business Days of a demand by the Bank pay to the Bank the amount of any increased cost incurred by it as a result of any change in or change in the interpretation or application of any law or regulation (including any law or regulation relating to taxation, or reserve asset, special deposit, cash ratio, liquidity or capital adequacy requirements or any other form of banking or monetary - -------------------------------------------------------------------------------- 23 - -------------------------------------------------------------------------------- control). Any such demand shall set out in reasonable detail the calculation and the cause of the amounts claimed and contain confirmation that the Bank is taking the same approach in relation to the majority of its other facilities of a similar nature. (b) In this Agreement "increased cost" means: (i) an additional cost incurred by the Bank as a result of it having entered into, or performing, maintaining or funding its obligations under, this Agreement; or (ii) that portion of an additional cost incurred by the Bank in making, funding or maintaining all or any advances comprised in a class of advances formed by or including the Loans made or to be made under this Agreement as is attributable to it making, funding or maintaining the Loans; or (iii) a reduction in any amount payable to the Bank or the effective return to the Bank under this Agreement or on its capital; or (iv) the amount of any payment made by the Bank, or the amount of any interest or other return foregone by the Bank, calculated by reference to any amount received or receivable by the Bank under this Agreement. 13.2 Exceptions Clause 13.1 (Increased costs) does not apply to any increased cost:- (a) compensated for by the payment of the MLA Cost; (b) compensated for by the operation of Clause 11 (Taxes) or which would have been compensated under that Clause but for the operation of Clause 11.4 (Exceptions from gross-up); (c) attributable to any change in the rate of tax on the overall net income of the Bank; (d) occurring as a result of any negligence or default of the Bank, including, without limitation, a breach by the Bank of any fiscal, monetary or capital adequacy limit imposed on it by any law or regulation; or (e) any increased cost attributable to any implementation of the proposals contained in any of:- (i) the statement of the Basle Committee on Banking Regulations and Supervisory Practices dated July 1988 and entitled "International Convergence of Capital Measurement and Capital Standards"; or (ii) the EC Solvency Ratio Directive, EC Own Funds Directive, or EC Capital Adequacy Directive or any law, regulation, rule, official directive, request or guideline (whether or not having the force of law) of any governmental body, central bank, agency, department, regulatory, self-regulatory or other authority in any jurisdiction, implementing, applying or supplementing any of them with which the Bank complies or is required to comply, - -------------------------------------------------------------------------------- 24 - -------------------------------------------------------------------------------- in each case as published before the date of this Agreement unless it results from any change in, or change in the interpretation of or application of, that statement, Directive, law, regulation, rule, official directive, request or guideline after the date of this Agreement. 14. ILLEGALITY AND MITIGATION 14.1 Illegality If it is or becomes unlawful in any jurisdiction for the Bank to give effect to any of its obligations as contemplated by this Agreement or to fund or maintain any Loan, then:- (a) the Bank may notify the Borrower accordingly; and (b) (i) the Borrower shall forthwith prepay all or part of the Loans to the extent necessary to avoid the relevant illegality together with accrued interest on that portion of the Loan; and (ii) the undrawn Commitments shall be reduced to such amount as would be lawful or (if no such amount would be lawful) to zero, in each case, on the last day before the relevant unlawfulness takes effect. 14.2 Mitigation If circumstances arise which would, or would on the giving of notice, result in:- (a) any additional amounts becoming payable under Clause 11 (Taxes); or (b) any amount becoming payable under Clause 13 (Increased costs); or (c) any prepayment, early payment or cancellation under Clause 14.1 (Illegality), then, without limiting the obligations of the Borrower under this Agreement and without prejudice to the terms of Clauses 11 (Taxes), 13 (Increased costs) and 14.1 (Illegality), the Bank shall, in consultation with the Borrower, take such steps as may be open to it to mitigate or remove such circumstance, including (without limitation) the transfer of its rights and obligations under this Agreement to another branch or another bank or financial institution acceptable to the Borrower, unless to do so would (in the opinion of the Bank) be prejudicial to it. 15.

(b) For the purposes of this Schedule 3: (i) "eligible liabilities" and "special deposits" have the meanings given to them at the time of application of the formula by the Bank of England; and (ii) "relevant period" in relation to each Interest Period, means: (A) if it is 3 months or less, that Interest Period; or (B) if it is more than 3 months, each successive period of 3 months and any necessary shorter period comprised in that Interest Period. (c) In the application of the formula, B, Y, L, X, S and Z are included in the formula as figures and not as percentages, e.g. if B = 0.5% and Y = 15%, BY is calculated as 0.5 x 15. - -------------------------------------------------------------------------------- 44 - -------------------------------------------------------------------------------- (d) (i) The formula is applied on the first day of each relevant period comprised in the relevant Interest Period. (ii) Each rate calculated in accordance with the formula is, if necessary, rounded upward to four decimal places. (e) If the Bank determines that a change in circumstances has rendered, or will render, the formula inappropriate, the Bank shall notify the Borrower of the manner in which the MLA Cost will subsequently be calculated which shall (so far as practicable) leave the Bank and the Borrower in no better or worse position than they would have been in if the relevant change in circumstances had not occurred. The manner of calculation so notified by the Bank shall, in the absence of manifest error, be binding on the Borrower. - -------------------------------------------------------------------------------- 45 - -------------------------------------------------------------------------------- SCHEDULE 3 FORM OF REQUEST To: UNION BANK OF SWITZERLAND From: YORKSHIRE POWER GROUP LIMITED Date: [_______________] YORKSHIRE POWER GROUP LIMITED - (pound)1,085,000,000 Credit Agreement dated [___________________________], 1997 1.
