                                                       Effective January 1, 2007

Dear Mike:

CONSULTING AGREEMENT

We are proposing the following consulting arrangements with National Grid USA
("NATIONAL GRID" and, together with its affiliates, the "GROUP") following your
separation from employment with the Group. On your agreement, this letter
becomes your CONSULTING AGREEMENT with National Grid.

1     CONSULTING ARRANGEMENT

(a)   ENGAGEMENT. Effective January 1, 2007, you will serve as a consultant to
      the Group. Your term as consultant will continue through June 30, 2007
      (or, if earlier, the termination of the consulting term in accordance with
      Section 4 hereof) (the "CONSULTING PERIOD").

(b)   SERVICES. During the Consulting Period you agree to be available to
      perform the following services, to the extent requested by National Grid:
      (i) assisting the Group with the closing of the KeySpan acquisition; (ii)
      making yourself reasonably available and cooperating with reasonable
      requests from the Group for information concerning any business or legal
      matters involving facts or events relating to the Group that may be within
      your knowledge; and (iii) providing such other services as reasonably
      requested from time to time by National Grid.

      You will use good faith efforts to perform the foregoing services to the
      best of your ability, and at a standard and at the times reasonably
      requested from time to time by National Grid. For the avoidance of doubt,
      during the Consulting Period you may serve on charitable boards or
      committees; with the prior approval of National Grid (such approval not to
      be unreasonably withheld or delayed), serve as a non-executive director on
      corporate boards or committees of companies that are not competitive with
      the Group; deliver lectures and teach at educational institutions; and
      manage personal investments (collectively, "PERSONAL ACTIVITIES"),
      provided that such activities do not individually or in the aggregate
      interfere with your obligations under this Consulting Agreement.

(c)   INDEPENDENT CONTRACTOR. You agree that you are performing the consulting
      services as an independent contractor and not as an employee of any member
      of the Group. You will be responsible for all taxes and other
      non-reimbursable expenses attributable to the rendition of your consulting
      services. Nothing in this Consulting Agreement shall be deemed to
      constitute a



      partnership or joint venture between any member of the Group and you, nor
      shall anything in this Consulting Agreement be deemed to constitute the
      Group or you as the agent of the other.

2     YOUR CONSULTING FEES

(a)   CONSULTING FEE. During each month of the Consulting Period during which
      you have provided services (or were reasonably available to provide
      services) to the Group (and provided you are not in breach of your
      obligations under the Separation and Release Agreement dated as of 31
      December 2006 ("SEPARATION AND RELEASE AGREEMENT") or the Settlement and
      Compromise Agreement dated as of 17 January 2007 ("SETTLEMENT AND
      COMPROMISE AGREEMENT"), you will receive a monthly consulting fee of
      $216,568. However, in the event that you become employed or engaged in any
      activity of a commercial nature (excluding, for the avoidance of doubt,
      any Personal Activities) prior to the end of the Consulting Period, this
      monthly consulting fee will be reduced dollar-for-dollar by the amount of
      the aggregate annual base salary (calculated as if such compensation were
      paid in equal monthly amounts) that you receive or are eligible to receive
      from your new employment or engagement, to the extent attributable to
      services performed for the new entity during the Consulting Period.

      You agree to promptly disclose to National Grid your commencement of any
      new employment or engagement and the annual base salary thereof, and to
      provide such substantiation as National Grid may reasonably request to
      determine the amount of the reduction applicable to the monthly consulting
      fee. For the avoidance of doubt, to the extent the actual amount of the
      monthly consulting fee that is paid to you after giving effect to such
      reduction is incorrect for any reason (in more than a de minimis amount),
      the party who should have paid more (National Grid) or the party who
      should have received less (yourself), as the case may be, shall promptly
      remit the applicable amount to the other.

      Your monthly consulting fee will be prorated for any partial months in the
      Consulting Period and will be payable in arrears no later than the end of
      each applicable month of the Consulting Period.

(b)   BUSINESS EXPENSES. You will be reimbursed for all reasonable business
      expenses you incur at the request of National Grid in performing your
      services under this Consulting Agreement, subject to substantiating such
      expenses in accordance with National Grid's reimbursement policies.

3     CERTAIN COVENANTS

(a)   CONFIDENTIAL INFORMATION. You understand and agree that, in the course of
      your consulting services with National Grid, you may acquire confidential
      business information and trade secrets concerning business, financial,
      technical and other information and material pertaining to the Group,
      including the Group's operations, processes, technology, contracts,
      personnel, advertiser and customer lists, future plans and methods of
      doing business, which are the property of the Group and which involve the
      Group and the Group's employees, which information you understand and
      agree would be extremely damaging to the Group if disclosed to a
      competitor or a third party (collectively, "CONFIDENTIAL INFORMATION").
      You agree to forever keep such Confidential Information secret and
      confidential, and that you shall not communicate



      or disclose to any third party, or use for your own account, without prior
      written consent of National Grid, any of the aforementioned Confidential
      Information. The restrictions set forth in this Section 3(a) will not,
      however, apply to Confidential Information which (i) becomes public other
      than through unauthorized disclosure by you, (ii) is lawfully and in
      good-faith made available to you outside the scope of your consulting
      services by a third party who did not derive it from the Group, and who
      imposes no obligation of confidence on you, (iii) was already known to you
      at the time it was disclosed to you, or (iv) is required to be disclosed
      by a governmental authority, regulatory body, or by order or subpoena of a
      court of competent jurisdiction, provided that prior to such disclosure,
      you shall, except as otherwise prohibited by law, give National Grid
      reasonable advance notice and an opportunity to take adequate measures to
      preserve the confidential nature of the information sought by such
      authority, body or court. You agree that the Group would be irreparably
      harmed by any violation, or threatened violation, of the prohibited
      disclosure of trade secrets and that, therefore, National Grid shall be
      entitled to an injunction prohibiting you from any violation or threatened
      violation of such disclosure restrictions.

(b)   RETURN OF PROPERTY. On or prior to the last day of the Consulting Period,
      you agree to return to National Grid all Group documents (whether in hard
      copy, soft copy or contained in a personal electronic device) and other
      materials (including office keys or access cards, company provided credit
      cards, laptop, etc.) that you have received or obtained from the Group
      during the course of your consulting with National Grid or that otherwise
      belong to the Group. You will not retain any hard or soft copies of any
      materials or other information that belongs to the Group.

(c)   INTELLECTUAL PROPERTY RIGHTS. You agree to assign to National Grid all
      right, title and interest in and to any inventions made, originated or
      developed as part of the consulting services with National Grid together
      with any other intellectual property rights directly arising out of the
      provision of the consulting services and further agree to assist National
      Grid (at National Grid's expense) in connection with any application for
      registration of intellectual property and to do all such acts and things
      at National Grid's expense as its legal advisers may advise are necessary
      or desirable in connection with any assignment or assistance.

(d)   INDEMNIFICATION. To the extent an unrelated third party institutes any
      action, suit or proceeding against you, National Grid agrees to indemnify
      you, defend you, and hold you harmless against all losses, liabilities,
      expenses, and costs (including reasonable attorney's fees, judgments,
      fines, and amounts paid in settlement) actually and reasonably incurred by
      you in connection with any threatened, pending, contemplated, or future
      action, suit, or proceeding to which you are, or are threatened to be,
      made a party arising from or relating to consulting services that National
      Grid directs you to provide under this Consulting Agreement, provided that
      you promptly notify National Grid of any such action, suit or proceeding,
      and submit to and cooperate with any reasonable procedures that the Group
      establishes in connection with the defense of such action, suit or
      proceeding and/or to avoid duplication of expenses or costs in connection
      with such defense. Notwithstanding the foregoing, you shall not be
      indemnified for actions arising from or relating to your bad faith, gross
      negligence or gross misconduct. You shall not be liable to National Grid
      for any losses, liabilities, expenses, or costs that National Grid may
      incur in connection with your performance of services under this
      Consulting Agreement unless caused by your bad faith, gross negligence, or
      gross misconduct.



(e)   COOPERATION. During the Consulting Period and continuing thereafter, you
      shall cooperate and assist the Group in any dispute, proceeding or
      investigation in which the Group is involved and in which you have been
      involved or which involves facts or events that existed or arose during
      the period of your employment or consultancy with National Grid relating
      to the business of the Group that may be within your actual knowledge.
      Such cooperation and assistance shall include (in each case upon being
      given reasonable advance notice and subject to your reasonable
      availability) providing information, documents, submitting to depositions
      and providing testimony, provided that you shall not be obligated to
      provide any such cooperation or assistance in a dispute, proceeding or
      investigation between the Group and any person or entity who is your
      employer after the Consulting Period. National Grid will reimburse all
      reasonable out-of-pocket expenses incurred by you in connection with
      fulfilling your obligations under this Section 3(e).

4     EARLY TERMINATION OF THIS AGREEMENT

(a)   MUTUAL EARLY TERMINATION. You and National Grid shall have the right to
      terminate this Consulting Agreement at any time prior to the end of the
      Consulting Period by mutual agreement.

(b)   EARLY TERMINATION BY NATIONAL GRID. National Grid shall have the right to
      terminate this Consulting Agreement prior to the end of the Consulting
      Period if:

      (i)   the Board of Directors of National Grid determines that you have
            repeatedly failed to perform the consulting services requested of
            you under this Agreement, provided that National Grid shall have
            provided at least 30 days prior notice of its intent to terminate
            (which notice shall also describe how you have failed to perform);
            and provided further that if the failure is capable of cure and you
            cure such failure to the reasonable satisfaction of the Board within
            30 days after receipt of the termination notice, such notice shall
            be cancelled; or

      (ii)  you breach any applicable provision of this Consulting Agreement,
            the Separation and Release Agreement or the Settlement and
            Compromise Agreement, excluding any immaterial or inadvertent breach
            that is not in bad faith; or

      (iii) you commit any act that would constitute gross misconduct or you are
            convicted of, or plead nolo contendere to, any felony or a
            misdemeanor involving fraud, dishonesty, or moral turpitude; or

      (iv)  National Grid in its sole discretion determines to terminate the
            Consulting Agreement prior to the end of the Consulting Period by
            paying you, in a lump sum, the amount that would have been payable
            had you served the full Consulting Period, provided that, National
            Grid shall provide at least 30 days prior notice of such intent to
            terminate.

      The Consulting Period will automatically terminate upon your death.

(c)   EARLY TERMINATION BY YOU. You shall have the right to terminate this
      Consulting Agreement prior to the end of the Consulting Period if National
      Grid breaches any applicable provision of



      this Consulting Agreement, excluding any immaterial or inadvertent breach
      that is not in bad faith.

(d)   For the avoidance of doubt, (i) the early termination rights under this
      Section 4 are in addition to any other rights or remedies the affected
      party may have under applicable law and (ii) the obligations under Section
      3 shall survive termination of this Consulting Agreement.

      and Release Agreement and the Settlement and Compromise Agreement, sets

      us. This Consulting Agreement will automatically terminate without any
      obligation (payment or otherwise) hereunder in the event that the
      Separation and Release Agreement is revoked prior to the Effective Date
      (as defined therein).

(d)   SEVERABILITY. If any provision of this Consulting Agreement is found by
      any court of competent jurisdiction (or legally empowered agency) to be
