50,000,000 Facility Letter entered into between Western Power Distribution (South West) plcand Svenska Handelsbanken AB dated as of October 11, 2016

The Facility shall be available for use by the Borrower only when the Bank (i) shall have received, to its satisfaction as to their form and substance, the documents and evidence set out in Schedule 1 and (ii) is satisfied that the other conditions detailed in Schedule 1 have been satisfied.

The Conditions Precedent set out in Schedule 1 are for the sole benefit of the Bank, and the Bank may in its sole and absolute discretion make the Facility, or a part thereof, available notwithstanding that one or more of such conditions have not been fulfilled on terms that such condition or conditions shall be fulfilled within such period or periods thereafter as the Bank shall determine unless the Bank shall otherwise agree to waive such condition or conditions in its sole and absolute discretion.

Utilisation of the Facility ("Facility Utilisation") will be calculated as the aggregate value of outstanding Drawings.

Facility Utilisation at any time shall not exceed the Limit and the Bank is not obliged to allow or continue to allow any utilisation in excess of the Limit.

The Facility is uncommitted and shall remain available to the Borrower until further notice but shall be subject to cancellation at any time by either the Bank or the Borrower giving written notice to the other. In the event of such cancellation no further Drawings shall be made available and the Bank will be entitled to require the Borrower to immediately repay all Drawings in accordance with the provisions of Clause 5.5.

The Bank shall review the Facility on each Review Date and may contact you to discuss your future requirements. Whenever we review the Facility, we may charge you a renewal fee.

All sums outstanding under the Facility together with interest thereon, and any fees, costs, charges and expenses payable hereunder shall be repayable upon demand at all times.

Borrowings by way of drawings shall be permitted at the Bank's discretion (together the "Drawings" each a "Drawing").

Each Drawing shall be for an amount, a period and at an interest rate, all to be mutually agreed at the time of each such Drawing, such period to expire no later than the next Quarter Day unless otherwise agreed by the Bank.

Interest on Drawings shall be payable by the Borrower in full in immediately available funds, on the relevant Maturity Date and on any date that a Drawing is renewed for a further period pursuant to Clause 5.4.

Each Drawing shall be repaid in full by the Borrower on the relevant Maturity Date unless the Bank, in its sole discretion, shall agree to renew any such Drawing for a further period in which case the Maturity Date for such Drawing shall be extended accordingly.

Notwithstanding any other term of this Facility Letter each Drawing together with interest thereon, and any fees, costs, charges and expenses payable hereunder shall be repayable upon demand and in the event that the Facility is cancelled or demand is made by the Bank, the Bank shall be entitled at the cost of the Borrower to break any interest period that may be applicable to a Drawing and the Borrower shall pay to the Bank the Breakage Fee and all Break Costs arising as a result thereof together with accrued interest. In the event that the Bank shall exercise such right all Drawings outstanding shall thereafter be fixed for such interest periods as shall be determined by the Bank in its sole and absolute discretion.

If there is a repayment, prepayment or recovery of all or any part of a Drawing other than on the relevant Maturity Date, then the Borrower will pay to the Bank on demand an amount equal to the Break Costs together with the Breakage Fee and the Borrower indemnifies the Bank against any other costs, liabilities or expenses incurred by the Bank in connection with that early repayment, prepayment or recovery.

Any notice of prepayment under this Facility Letter shall be irrevocable and the provisions of this Clause 5 shall apply to any prepayment.

If the prepayment sum is received by the Bank after 10 am then the Bank may treat such prepayment as if it had been received on the next Business Day. Any prepayment must be accompanied by any Breakage Fee and all Break Costs arising as a result thereof together with accrued interest.

In consideration of the Bank making the Facility available hereunder the Borrower shall pay to the Bank, the Bank's Fees which if not previously paid shall be deducted from any Drawing made hereunder. Any fees as set out in Clause 1.1 not due on first utilisation shall be debited to the Borrower’s account and be payable in advance at the time or times and in the manner set out in Clause 1.1.

In the event that the level of administration undertaken by the Bank in connection with the operation and monitoring of the Facility shall in the opinion of the Bank have increased or be likely to increase from that envisaged by the Bank when the Facility was originally agreed then the Bank shall have the right to charge the Borrower an Administration Fee.

The Borrower shall, within three Business Days of a demand by the Bank, pay the Bank the amount of any Increased Costs incurred by the Bank as a result of (i) the introduction of or any change in (or in the interpretation, administration or application of) any law, regulation or directive (whether or not having the force of law) or (ii) compliance with any law, regulation or directive (whether or not having the force of law) made after the date of this Facility Letter.

In this Facility Letter "Increased Costs" means:

a reduction in the rate of return from the Facility or on the Bank’s overall capital;

an additional or increased cost; or

a reduction of any amount due and payable under this Facility Letter,

The Bank prior to making a claim pursuant to Clause 7.1 above shall notify the Borrower of the event giving rise to the claim and shall, as soon as practicable after a demand by the Borrower, provide a certificate confirming the amount of its Increased Costs.

If the Borrower shall fail to pay any sum due hereunder or under the judgement of any court in connection herewith on the due date therefor, then as a separate obligation the Borrower shall pay to the Bank interest at the Default Rate on any such sum due to the Bank up to the date on which such sum is repaid and any other amounts outstanding under this Facility Letter have been paid in full. Interest shall be payable at the rate both before and after demand, court decree or judgment on such dates advised by the Bank to the Borrower any such interest which is not paid when due shall be added to the overdue sum and itself bear interest accordingly.

The Bank's certificate as to the amounts due pursuant to this Clause 7 shall be final and conclusive, save for manifest error.

All interest shall accrue from day to day and be calculated on the basis of the actual number of days elapsed within a year of 365 days.

All sums payable by the Borrower to the Bank shall be paid without deduction for or on account of any set-off or counter-claim and free and clear of any deduction or withholding of any nature (including taxation) unless such a deduction or withholding is required by law.

If any amount is required by law to be deducted or withheld from any sum payable hereunder then the Borrower shall pay such an additional amount as will ensure that, after the making of such deduction or withholding, the Bank shall receive a net sum equal to the sums which the Bank would have received had no such deduction or withholding been required to be made.

The Borrower shall (within three Business Days of demand by the Bank) pay to the Bank an amount equal to the loss, liability or cost which the Bank determines will be or has been (directly or indirectly) suffered for or on account of Tax by the Bank in respect of the Facility Letter.

Clause 9.4 above shall not apply:

with respect to any Tax assessed on the Bank under the law of the jurisdiction in which the Bank is incorporated or, if different, the jurisdiction (or jurisdictions) in which the Bank is treated as resident for tax purposes, if that Tax is imposed on or calculated by reference to the net income received or receivable (but not any sum deemed to be received or receivable) by the Bank; or

to the extent a loss, liability or cost is compensated for by an increased payment under Clause 9.3.

If the Bank makes (or intends to make) a claim under Clause 9.4 above, it shall notify the Borrower as soon as is reasonably practicable of the event which has caused (or will cause) that claim, however, the Bank’s entitlement to exercise its rights under Clause 9.4 above is not conditional on such notification being made in accordance with this Clause 9.6.

For the purposes of Clauses 9.4 and 9.5:

In addition to any other rights to which it may be entitled the Bank may retain, set off or appropriate any credit balances in name of the Borrower (whether current or not yet due) against the Borrower’s obligations to the Bank under this Facility Letter. The Bank may exercise any of these rights without prior notice both before and after demand and in so doing may convert to sterling at the prevailing market rate of exchange any balance which is in a currency other than sterling.

Nothing expressed or implied in this Facility Letter or any other document in connection herewith shall be regarded as in any way negating or affecting any right which the Bank may have under applicable law to apply any credit balances to which the Borrower is entitled on any account of the Borrower in or towards satisfaction of any sum due from the Borrower hereunder.

No failure on the part of the Bank to exercise, and no delay on its part in exercising, any right or remedy under this Facility Letter will operate as a waiver thereof, nor will any single or partial exercise of any right or remedy preclude any other or further exercise thereof or the exercise of any other right or remedy. The rights and remedies provided in this Facility Letter are cumulative and not exclusive of any rights or remedies provided by law or otherwise.

Save to the extent expressly provided to the contrary in this Facility Letter a person who is not a party to this Facility Letter may not enforce any of its terms under the Contracts (Rights of Third Parties) Act 1999.

The Borrower may not assign, transfer or otherwise dispose of all or any part of its rights, benefits or obligations under this Facility Letter.

Subject to clause 14.3 below, the Bank may, with the prior written consent of the Borrower (such consent not to be unreasonably withheld or delayed) at any time and its own cost assign, novate or transfer all or any part of its rights, benefits and obligations under this Facility Letter or grant participations therein to any one or more banks or financial institutions and the Borrower and any other party to this Facility Letter hereby agree to execute any documents required to enable the Bank so to do (provided that the Borrower and any such other party shall neither be required thereby to pay any greater amount to satisfy its obligations hereunder nor be responsible for any legal or statutory costs or duties arising therefrom) and the Borrower and any other party to this Facility Letter further agrees that the Bank may disclose any information to any such bank or financial institution for said purpose.

The consent of the Borrower will be deemed to have been given if:

the transfer is to an Affiliate of the Bank;

a breach of the Borrower’s obligations has occurred and is continuing; or

within 10 Business Days of receipt by the Borrower of a written application for consent, it has not been expressly refused, provided, in each case, that at the time of the proposed transfer no deduction or withholding would be required by law in respect of any payment to the transferee at such time to the extent that no deduction or withholding would have been required in respect of a payment to the Bank.

The Borrower agrees that the costs and expenses, including legal fees, disbursements registration fees and value added tax thereon, incurred by the Bank in connection with the preparation, negotiation, execution and registration of this Facility Letter, and any other documents required in connection with the Facility shall be for the Borrower’s account and the Borrower hereby indemnifies the Bank in respect of payment thereof.

The Borrower further undertakes to reimburse and indemnify the Bank for any and all costs, interest, charges and expenses incurred by the Bank, as well after as before judgement, in connection with preserving, enforcing or seeking to preserve or enforce its rights in respect of this Facility Letter or any amendment thereto, or in connection with the granting of any approvals or consents hereunder.
