7.5

For purposes of this Agreement, “employee benefit and welfare plans” do not include any severance, termination or redundancy plan, program or arrangement operated by any member of the Group.

7.6

The Company recognizes that the Executive presently has the right to terminate employment by reason of “Good Reason” under the terms of that certain Employment Agreement dated as of February 24, 2005 between KeySpan Corporation and the Executive as amended August 2, 2007 (the “KeySpan Employment Agreement”), and receive severance payments and benefits under the KeySpan Employment Agreement. In order to incentivize the Executive to continue in the employ of the Company during the critical transition period following the KeySpan Merger Date, the parties hereby agree to the following:

7.6.1

On January 10, 2008 (the “Payment Date”), the Company will pay the Executive the amount(s) and benefit(s) (the “Buyout Amount”) set forth on Schedule A of this Agreement, provided that the Executive has not been terminated for “Cause” (as defined in the KeySpan Employment Agreement except that reference to “laws of the United States” in section 4(b)(i) thereof is hereby amended to state “laws of the United States or the United Kingdom” and references to “Company” and “Board” in sections 4(b)(i), (ii) and (iii) are hereby amended to mean “National Grid plc” and the “Board of Directors of National Grid plc,” respectively) prior to then. However, should the Executive die before the Payment Date, the Buyout Amount will be paid to the Executive’s estate within 30 days after his death (but not prior to January 1, 2008). The Company’s obligation to pay the Buyout Amount to the Executive pursuant to this clause 7.6.1 shall not be subject to the Executive’s continued employment with the Company or any other conditions (other than clause 7.6.2(v)).

7.6.2

The Executive agrees that (i) the Buyout Amount represents the Executive’s full entitlement under the KeySpan Employment Agreement and, when paid, will represent full settlement of his severance rights under the KeySpan Employment Agreement, other than his rights under Section 9 of the KeySpan Employment Agreement (relating to certain excise tax gross-up payments), his rights to retirement benefits set forth in Appendix A of the KeySpan Employment Agreement and certain other rights and benefits referenced in Schedule B of this Agreement, (ii) from the Commencement Date, the Executive will not have any new or prospective rights or entitlements under the KeySpan Employment Agreement, (iii) no new “Protection Period” (as defined in the KeySpan Employment Agreement) will be triggered following the KeySpan Merger Date; (iv) the certified public accounting firm under Section 9 of the KeySpan Employment Agreement shall be the Parent’s auditors, or such other certified public accounting firm of national standing selected by the Company, but subject to the Executive’s approval (which approval shall not be unreasonably withheld); and (v) the Executive must execute and deliver an effective general release in the form attached as Exhibit B to this Agreement as a condition to receiving the Buyout Amount.

7.7		For the avoidance of doubt, from and after the date of this Agreement, and notwithstanding the settlement of certain rights of the Executive under the KeySpan Employment Agreement as set forth in clause 7.6, the Executive will continue to participate in, and will retain any applicable vested rights under, the applicable arrangements pursuant to clause 7.5 as well as the KeySpan Corporation arrangements referenced in Schedule B to this Agreement.

8		Expenses

8.1		The Company will refund to the Executive all reasonable business expenses properly incurred by him in performing his duties under this Agreement, provided that these are incurred in accordance with Company policy from time to time. The Company will require the Executive to produce receipts or other documents as proof that he has incurred any expenses he claims.

8.2		If the Executive is provided with a credit or charge card by the Company this must only be used for expenses which he incurs in performing the duties of the Employment.

9		Confidentiality

9.1		Without prejudice to the common law duties which he owes to the Group the Executive agrees that he will not, except in the proper performance of his duties, copy, use or disclose to any person any of the Group’s trade secrets or confidential information. This restriction will continue to apply after the termination of the Employment without limit in time but will not apply to trade secrets or confidential information which become public other than through unauthorized disclosure by the Executive. The Executive will use his best endeavors to prevent the unauthorized copying, use or disclosure of such information.

For the purposes of this Agreement, trade secrets and confidential information include but will not be limited to technical data, know-how, information technology and know-how relating to the Group, customer lists, pricing information, information relating to the Group’s marketing and financial strategies, marketing materials, financial information and any other information concerning the affairs of the Group or the personnel of the Group which is for the time being confidential, which the Executive is told is confidential or which by its nature is obviously confidential and whether such information is in written, oral, visual, electronic or any other form.

9.2		In the course of the Employment the Executive is likely to obtain trade secrets and confidential information belonging or relating to other Group Companies and other persons. He will treat such information as if it falls within the terms of clause 9.1 and clause 9.1 will apply with any necessary amendments to such information. If requested to do so by the Company the Executive will enter into an agreement with other Group Companies and any other persons in the same terms as clause 9.1 with any amendments necessary to give effect to this provision.

9.3		Nothing in this Agreement should or will prevent the Executive from raising any concerns in accordance with the provisions of the National Grid Standards of Ethical Business Conduct and the Requirement for Written Codes of Ethics for Employees (incorporating Whistleblowing Protection).

10		Intellectual Property

10.1		The Executive must disclose immediately to the Company any discovery or invention, secret process or improvement in procedure made or discovered

by the Executive during his employment in connection with or in any way affecting or relating to the business of the Company or any Group Company or capable of being used or adapted for use in or in connection with any such company (“Inventions”) which Inventions will belong to and be the absolute property of the Company or such other person, firm, company or organization as the Company may require.

10.2		If requested by the Board (whether during or after the termination of his employment) the Executive will at the expense of the Company apply or join in applying for letters patent or other similar protection in the United States, the United Kingdom or any other part of the world for all Inventions and will do everything necessary (including executing documents) for vesting letters patent or other similar protection when obtained and all right and title to and interest in all Inventions in the Company absolutely and as sole beneficial owner or in such other person, firm, company or organization as the Company may require.

10.3		The Executive will (both during and after the termination of his employment) at the Company’s expense anywhere in the world and at any time promptly do everything (including executing documents) that may be reasonably required by the Board to defend or protect for the benefit of the Company all Inventions and the right and title of the Company to them.

10.4		The entire copyright and all similar rights (including future copyright, the right to register trade marks or service marks and the right to register designs and design rights) throughout the world in works of any description produced by the Executive in the course of or in connection with his employment (“Works”) will vest in and belong to the Company absolutely throughout the world for the full periods of protection available in law including all renewals and extensions.

10.5		The Executive will (both during and after the termination of his employment) at the Company’s request and expense anywhere in the world and at any time promptly do everything (including executing documents) that may be reasonably required by the Board to assure, define or protect the rights of the Company in all Works.

10.6		The Executive will not make copies of any computer files belonging to any Group Company or their service providers and will not introduce any of his own computer files into any computer used by any Group Company in breach of any Group Company policy, unless he has obtained the consent of the Board.

10.7

By entering into this Agreement the Executive irrevocably appoints the Company to act on his behalf to execute any document and do anything in

his name for the purpose of giving the Company (or its nominee) the full benefit of the provision of clause 10 or the Company’s entitlement under statute. If there is any doubt as to whether such a document (or other thing) has been carried out within the authority conferred by this clause 10.7, a certificate in writing (signed by any director or the secretary of the Company) will be sufficient to prove that the act or thing falls within that authority.

Termination and Suspension

11.1		The Employment will continue until the second anniversary of the KeySpan Merger Date unless terminated earlier by (a) the mutual written agreement of the Executive and the Company or (b) either party giving written notice as set out in clause 11.2, 11.4 or 11.5.

11.2		Until the first anniversary of the KeySpan Merger Date, either party may terminate the Employment by giving not less than 12 months’ written notice to the other. After the first anniversary of the KeySpan Merger Date either party may terminate the Employment by giving written notice equal to the number of days that is one day less than the total number of days remaining until the second anniversary of the KeySpan Merger Date.

11.3		The Company may at its sole and absolute discretion pay base salary alone (as referred to in clause 7.1, at the rate in force at the time such payment is made) in lieu of any unexpired period of notice (less any deductions the Company is required by law to make) specified in clause 11.2. Notwithstanding the preceding sentence, in the event the Company determines to make a payment in lieu of notice in connection with a notice of termination (pursuant to clause 11.2) that is given prior to the Payment Date of the Buyout Amount, the payment in lieu of notice period shall not exceed the applicable unexpired period of notice between the date of the notice of termination and the Payment Date of the Buyout Amount. Any payment by the Company in lieu of any unexpired period of notice will be made as soon as practicable and, in any event, completed within 2.5 months following the later of the end of the calendar year or the Company fiscal year that occurs immediately following initial notice under clause 11.2. The Executive is not entitled to participate in or benefit from any severance, termination or redundancy plan, program or arrangement maintained by any Group Company; for the avoidance of doubt, this is notwithstanding anything to the contrary that may be contained in such severance, termination or redundancy plan, program or arrangement.

11.4

The Company may terminate the Employment by giving written notice to take immediate effect whether or not the Executive’s entitlement to sick pay,

contractual or otherwise, has been exhausted if the Executive does not perform the duties of the Employment for a period of 180 days (whether or not consecutive). This notice can be given whilst the Executive continues not to perform his duties or on expiration of the 180 day period. In this clause, ‘days’ includes Saturdays, Sundays and public holidays.

11.5

The Company may terminate the Employment by giving written notice to take immediate effect if the Executive:

	11.5.1		has not performed his duties under this Agreement to the standard required by the Board; or

	11.5.2		commits any serious or persistent breach of his obligations under this Agreement; or

11.6

Where the Company terminates the Employment by giving written notice to take immediate effect in accordance with either clause 11.4 or 11.5 (or in the event of the Executive’s and the Company’s mutual written agreement

to terminate the Employment or in the case of the Executive’s death), for the avoidance of doubt there is no obligation to give notice as set out in clause 11.1 or any other period of notice or to make any payment in lieu of notice.

11.7		The Executive will have no claim for damages or any other remedy against the Company if the Employment is terminated for any of the reasons set out in clause 11.4 or 11.5.

11.8		When the Employment terminates the Company may deduct from any money due to the Executive (including remuneration) any amount which he owes to any Group Company.

11.9		The Company may suspend the Executive from the Employment on full base salary at any time, and for any reason for a reasonable period to investigate any matter in which the Executive is implicated or involved (whether directly or indirectly) and to conduct any related disciplinary proceedings and such suspension shall not entitle the Executive to claim that he has been constructively dismissed.

11.10		As a condition to making the payments and providing the benefits stated in this clause 11 (or in clause 12.5 below), the Company may require the Executive to execute and deliver a general release in which he (i) releases all claims that he may have in respect of his employment against any Group Company and any of their respective past or present officers, directors or employees other than his rights under this Agreement or another agreement into which he and the Company subsequently enter and (ii) covenants that he has not filed and will not file any civil action, suit, arbitration, administrative charge, or legal proceeding against any of the released parties in respect of the released claims.

11.11		Unless the Group waives this requirement, the termination of the Employment for any reason will constitute the Executive’s resignation from (1) any director, officer or employee position he then has with any Group Company and (2) all fiduciary positions (including as trustee) he holds with respect to any pension plans or trusts established by any Group Company. The Executive agrees that this Agreement will serve as his written notice of resignation in this circumstance.

12		Garden Leave

12.1		Neither the Company nor any Group Company is under any obligation to provide the Executive with any work. At any time after notice to terminate the Employment is given by either party under clause 11 above, or if the Executive resigns without giving due notice and the Company does not

accept his resignation, the Company may, at its absolute discretion, require the Executive to take a period of absence called “garden leave” for a maximum period of time equal to the lesser of (a) 6 months or (b) the number of days until the second anniversary of the KeySpan Merger Date (the “Garden Leave Period”). The provisions of this clause shall apply to any Garden Leave Period.

12.2

The Company may require that the Executive will not, without prior written consent of the Board, be employed or otherwise engaged in the conduct of any activity, whether or not of a business nature during the Garden Leave Period. Further, if so requested by the Company, the Executive will not:

	12.2.3		contact or have any communication with any employee, officer, director, agent or consultant of the Parent or any other Group Company in relation to the business of the Parent or any other Group Company; or

	12.2.4		remain or become involved in any aspect of the business of the Parent or any other Group Company except as required by such companies.

12.3

The Company may require the Executive:

	12.3.1		to comply with the provisions of clause 15; and

	12.3.2		to immediately resign from any directorship, trusteeships or other offices which he holds in the Parent, any other Group Company or any other company where such directorship or other office is held as a consequence or requirement of the Employment, unless he is required to perform duties to which any such directorship, trusteeship or other office relates in which case he may retain such directorships, trusteeships or other offices while those duties are ongoing. The Executive hereby irrevocably appoints the Company to be his attorney to execute any instrument and do anything in his name and on his behalf to effect his resignation if he fails to do so in accordance with this clause 12.3.2.

12.4

During the Garden Leave Period, the Executive will be entitled to receive his base salary and all contractual benefits (excluding bonuses) in

accordance with the terms of this Agreement. Any unused vacation accrued at the commencement of the Garden Leave Period and any vacation accrued during any such period will be deemed to be taken by the Executive during the Garden Leave Period.

12.5		At the end of or at any time during the Garden Leave Period, the Company may, at it sole and absolute discretion, pay the Executive base salary alone (as defined in clause 7.1) in lieu of the balance of any period of notice given by the Company or the Executive (less any deductions the Company is required by law to make). In any event, and in accordance with clause 11.3, the Company’s payment in lieu of the unexpired period of notice, as well as payment of any base salary attributable to the Garden Leave Period, will be completed within 2.5 months following the later of the end of the calendar year or the Company fiscal year that occurs immediately following initial notice under clause 11.2.

12.6		During the Garden Leave Period:

	12.6.1		the Executive shall provide such assistance as the Company or any Group Company may reasonably require to effect an orderly handover of his responsibilities to any individual or individuals appointed by the Company or any Group Company to take over his role or responsibilities;

	12.6.2		the Executive shall make himself reasonably available to deal with requests for information, provide assistance, be available for meetings and to advise on matters relating to work (unless the Company has agreed the Executive may be unavailable for a period); and

	12.6.3		the Company may appoint another person to carry out his duties in substitution for the Executive.

12.7		All duties of the Employment (whether express or implied), including without limitation the Executive’s duties of fidelity, good faith and exclusive service, shall continue throughout the Garden Leave Period save as expressly varied by this clause 12.

12.8		The Executive agrees that the exercise by the Company of its rights pursuant to this clause 12 shall not entitle the Executive to claim that he has been constructively dismissed.

13		Restrictions after Termination of Employment

16.1		The Executive’s office as a director of the Parent or any other Group Company is subject to the Articles of Association or Certificate of Incorporation of the relevant company (as amended from time to time).

16.2		The Executive must resign from any office held in any Group Company if he is asked to do so by the Company.

16.3		If the Executive does not resign as an officer of a Group Company, having been requested to do so in accordance with clause 16.2, the Company will be appointed as his attorney to effect his resignation. By entering into this Agreement, the Executive irrevocably appoints the Company as his attorney to act on his behalf to execute any document or do anything in his name necessary to effect his resignation in accordance with clause 16.2. If there is any doubt as to whether such a document (or other thing) has been carried out within the authority conferred by this clause 16.3, a certificate in writing (signed by any director or the secretary of the Company) will be sufficient to prove the act or thing falls within that authority.

16.4		The termination of any directorship or other office held by the Executive will not terminate the Executive’s employment or amount to a breach of terms of this Agreement by the Company.

16.5		During the Employment the Executive will not do anything which could cause him to be disqualified from continuing to act as a director of any Group Company.

16.6		The Executive must not resign his office as a director of any Group Company without the agreement of the Parent.

17		Notices

17.1		Any notices given under this Agreement must be given by letter or fax. Notice to either the Parent or the Company must be addressed to its respective registered office at the time the notice is given. Notice to the Executive must be given to him personally or sent to his last known address.

17.2		Except for notices given by hand, notices given by post will be deemed to have been given on the next working day after the day of posting and notices given by fax will be deemed to have been given in the ordinary course of transmission.

18		Data Protection Act 1998

18.1		For the purposes of the Data Protection Act 1998 (the “Act”) the Executive gives his consent to the holding, processing and disclosure of personal data (including sensitive data within the meaning of the Act) provided by the Executive to the Company for all purposes relating to the performance of this Agreement including, but not limited to:

	18.1.1		administering and maintaining personnel records;

	18.1.2		paying and reviewing base salary and other remuneration and benefits;

	18.1.3		providing and administering benefits (including if relevant, pension, life assurance, permanent health insurance and medical insurance);

	18.1.4		undertaking performance appraisals and reviews;

	18.1.5		maintaining sickness and other absence records;

	18.1.6		taking decisions as to the Executive’s fitness for work;

The Executive agrees to comply with the terms of the Act in relation to such data and to abide by the Company’s data protection policy issued from time to time.

19		Disputes

19.1		Mandatory Arbitration. Subject to the provisions of this clause 19, any controversy or claim between the Executive and the Company arising out of or relating to or concerning this Agreement (including the covenants contained in clause 13) or any aspect of his employment with the Company or the termination of that employment (together, an “Employment Matter”) will be finally settled by arbitration in the County of New York administered by the American Arbitration Association (the “AAA”) under its Employment Arbitration Rules then in effect. However, the AAA’s Employment Arbitration Rules will be modified in the following ways: (i) the award must not be a compromise but must be the adoption of the submission by one of the parties, (ii) each arbitrator will agree to treat as confidential evidence and other information presented to them to the same extent as the information is required to be kept confidential under clause 9, (iii) there will be no authority to award punitive damages (and the Executive and the Company

agree not to request any such award), (iv) the optional Rules for Emergency Measures of Protections will apply, (v) there will be no authority to amend or modify the terms of this Agreement except as provided in clause 20.2 (and the Executive and the Company agree not to request any such amendment or modification), (vi) an award must be rendered within ten business days of the parties’ closing statements or submission of post-hearing briefs and (vii) the arbitration will be conducted before a panel of three arbitrators, one selected by the Executive within 10 days of the commencement of the notice of arbitration, one selected by the Company in the same period and the third selected jointly by these arbitrators (or, if they are unable to agree on an arbitrator within 30 days of the commencement of arbitration, the third arbitrator will be appointed by the American Arbitration Association; provided that the arbitrator shall be a partner or former partner at a nationally recognized law firm who is experienced in employment matters).

19.2		Injunctions and Enforcement of Arbitration Awards. The Executive or the Company may bring an action or special proceeding in a state or federal court of competent jurisdiction sitting in the County of New York to enforce any arbitration award under clause 19.1. Also, the Company may bring such an action or proceeding, in addition to its rights under clause 9 or 13 and whether or not an arbitration proceeding has been or is ever initiated, to temporarily, preliminarily or permanently enforce any part of clause 9 or 13. The Executive agrees that (i) violating any part of clause 9 or 13 would cause damage to the Group that cannot be measured or repaired, (ii) the Company therefore is entitled to an injunction, restraining order or other equitable relief restraining any actual or threatened violation of clause 9 or 13, (iii) no bond will need to be posted for the Company to receive such an injunction, order or other relief and (iv) no proof will be required that monetary damages for violations of clause 9 or 13 would be difficult to calculate and that remedies at law would be inadequate.

19.3		Jurisdiction and Choice of Forum. The Executive and the Company irrevocably submit to the exclusive jurisdiction of any state or federal court located in the County of New York over any Employment Matter that is not otherwise arbitrated or resolved according to clause 19.1. This includes any action or proceeding to compel arbitration or to enforce an arbitration award. Both the Executive and the Company (i) acknowledge that the forum stated in this clause 19.3 has a reasonable relation to this Agreement and to the relationship between the Executive and the Company and that the submission to the forum will apply even if the forum chooses to apply non-forum law, (ii) waive, to the extent permitted by law, any objection to personal jurisdiction or to the laying of venue of any action or proceeding

covered by this clause 19.3 in the forum stated in this clause 19.3, (iii) agree not to commence any such action or proceeding in any forum other than the stated in this clause 19.3 and (iv) agree that, to the extent permitted by law, a final and non-appealable judgment in any such action or proceeding in any such court will be conclusive and binding on the Executive and the Company. However, nothing in this Agreement precludes the Executive or the Company from bringing any action or proceeding in any court for the purpose of enforcing the provisions of clause 19.1 and this clause 19.3.

19.4		Waiver of Jury Trial. To the extent permitted by law, the Executive and the Company waive any and all rights to a jury trial with respect to any Employment Matter.

19.5		This Agreement is governed by and will be interpreted in accordance with the laws of the State of New York applicable to contracts made and performed in New York, excluding application of its conflict of laws principles.

19.6		This Agreement will be binding on, inure to the benefit of and be enforceable by the parties and their respective heirs, personal representatives, successors and assigns. This Agreement does not confer any rights, remedies, obligations or liabilities to any entity or person other than the parties hereto and their permitted successors and assigns.

20		Miscellaneous

20.1		This Agreement may be entered into in any number of counterparts, all of which taken together shall constitute one and the same instrument. Any party may enter into this Agreement by executing any such counterpart.

20.2		This Agreement may only be modified by the written agreement of the parties.

20.3		The Executive cannot assign this Agreement to anyone else.

20.4		References in this Agreement to rules, regulations, policies, handbooks or other similar documents which supplement it, are referred to in it or describe any pensions or other benefits arrangement are references to the versions or forms of the relevant documents as amended or updated from time to time.

20.6		The Company may withhold from any amounts payable under this Agreement any applicable withholding in respect of federal, state, local or foreign taxes.

20.7		This Agreement supersedes any previous written or oral agreement between the parties in relation to the matters dealt with in it, including the KeySpan Employment Agreement (except with respect to the sections contained therein that are specifically referenced herein and, where applicable, as modified herein). It contains the whole agreement between the parties relating to the Employment at the date the agreement was entered into (except for those terms implied by law which cannot be excluded by the agreement of the parties). The Executive acknowledges that he has not been induced to enter into this Agreement by any representation, warranty or undertaking not expressly incorporated into it. The Executive agrees and acknowledges that his only rights and remedies in relation to any representation, warranty or undertaking made or given in connection with this Agreement (unless such representation, warranty or undertaking was made fraudulently) will be for breach of the terms of this Agreement, to the exclusion of all other rights and remedies (including those in tort or arising under statute).

20.8		Neither party’s rights or powers under this Agreement will be affected if:

	20.8.1		one party delays in enforcing any provision of this Agreement; or

	20.8.2		one party grants time to the other party.

20.9		References to any statutory provisions include any modifications or re-enactments of those provisions.

20.10		Headings will be ignored in construing this Agreement.

20.11		If either party agrees to waive his or its rights under a provision of this Agreement, that waiver will only be effective if it is in writing and it is signed by him or it. A party’s agreement to waive any breach of any term or condition of this Agreement will not be regarded as a waiver of any subsequent breach of the same term or condition or a different term or condition.

20.12		This Agreement is in consideration of the mutual covenants contained in it. The parties hereto acknowledge the receipt and sufficiency of the consideration to this Agreement and intend this Agreement to be legally binding. This Agreement shall not be construed more strictly with regard to either party.

20.13

To the extent any reimbursements or in-kind benefits due to the Executive under this Agreement constitute “deferred compensation” under section

409A of the Code, any such reimbursements or in-kind benefits shall be paid to the Executive in a manner consistent with, and shall otherwise comply with, Treas. Reg. section 1.409A-3(i)(1)(iv). Any excise tax gross-up payments that become due under clause 7.6.2 of this Agreement will be paid in a manner consistent with, and shall otherwise comply with, Treas. Reg. section 1.409A-3(i)(1)(v). Further, in the event that any payment made as a direct result of this Agreement is deemed to constitute “deferred compensation” under section 409A and is payable upon “separation from service” (as defined in section 409A) such payment(s) will be delayed for six (6) months if the Executive is a “specified employee” (as defined in section 409A) at the time of “separation from service.” The payment of salary in lieu of notice under clause 11 of this Agreement, or during any Garden Leave Period under clause 12 of this Agreement, is intended to be made within the short-term deferral period exemption under section 409A, and will be made accordingly. Any payments that result from any plan or arrangement that is separately subject to the terms of section 409A will be made in accordance with the applicable terms of such plan or arrangement, except to the extent explicitly modified by this Agreement.
