Agreement to reflect certain changes in their arrangements resulting from the
spinoff of GenTek Inc. Therefore, Manager and the Company desire to amend and

acknowledged, the parties to this Agreement hereby agree as follows:

           1. Services of Manager. Subject to the terms and conditions of this

      Company including strategic guidance and advice with respect to tax
      employee benefits, insurance and risk management matters; and

                (b) provide such other corporate services of such nature and

      time.

Company the services of such of its employees and consultants as are necessary,

the Company a specific employee or consultant of the Manager for any reason,
including without limitation the death or disability of such employee or
consultant, the termination of an employment or consulting agreement with any
such person or the assignment of such employee or consultant to other duties,
shall not constitute a default hereunder.

           5. Limited Liability of Manager. (a) Neither Manager nor any
director, officer, stockholder, employee or agent of Manager makes any express

subsidiaries, to any of its stockholders or to any third party for any expense,
claim, loss or damage, including, without limitations indirect, special,
consequential or exemplary damages suffered other than by reason of Manager's
intentional failure to perform the services to be performed by Manager pursuant
to this Agreement, or by reason of action taken by Manager which was in bad
faith and in a manner not reasonably believed by Manager to be in the best
interests of the Company.

           (c) Manager shall not be liable to the Company, to any of its
subsidiaries, to any of its stockholders or to any third party for the
consequences of any failure to perform or delay in performing any of its
obligations under this Agreement if that failure shall be caused by events or
circumstances beyond its control including, without limitation, by strikes or
labor disputes; provided that Manager shall reasonably provide prompt notice to
the Company or its subsidiaries of such inability and the reasons therefor.

           6. Indemnification. The Company will indemnify Manager and each
director, officer, stockholder, employee and agent of Manager against any
losses, claims, damages or liabilities (including legal or other expenses
reasonably incurred in investigating or defending against any such losses,
claims, damages or liabilities), joint or several ("Liabilities"), to which any
of such persons may become subject by reason of such person's being a director,
officer, stockholder, employee or agent of Manager (but only to the extent that
such Liabilities arise out of or relate to and with respect to Services);
provided that the party to be indemnified acted in good faith and in a manner he
reasonably believed to be in or not opposed to the best interests of the
Company, and, with respect to any criminal action or proceeding, had no
reasonable cause to believe his conduct was unlawful.

           The Company may pay expenses (including attorneys' fees) incurred by
Manager and any director, officer, stockholder, employee and agent of Manager in
defending any civil, criminal, administrative or investigative action, suit or
proceedings, in advance of the final disposition of such action, suit or
proceeding, upon receipt of an undertaking by or on behalf of a party which may
be entitled to indemnification to repay such amount if it shall be ultimately
determined that he is not entitled to be indemnified by the Company as
authorized in this Agreement.

commencing on the fifteenth day after the Notice Date, meet and negotiate in
good faith in an attempt to resolve the matter in dispute. If such attempt

parties involved to pursue the procedure set forth below by delivering written
notice to them of such party's desire to do so within five (5) days after the
end of such negotiation period.

           (c) Arbitration. Any dispute arising out of or relating to this
Agreement or the breach, termination or validity hereof which are not resolved
by the foregoing procedure shall be finally settled by arbitration conducted
expeditiously in accordance with the Center for Public Resources Rules for

for Public Resources shall appoint a neutral advisor from its National CPR
Panel. The arbitration shall be governed by the United States Arbitration Act, 9
U.S.C. 'SS''SS'1-16, and judgment upon the award rendered by the arbitrators may

shall be Boston, Massachusetts.

accordance with the CPR Rules as he/she deems appropriate; however, such
proceedings shall be guided by the following agreed upon procedures:

           (i) mandatory exchange of all relevant documents, to be accomplished
      within forty-five (45) days of the initiation of the procedure;

          (ii) no other discovery;

         (iii) hearings before the neutral advisor which shall consist of a
      summary presentation by each side of not more than three hours, such
      hearings to take place on one or two days at a maximum; and

          (iv) decision to be tendered not more than ten (10) days following
      such hearings.

           Notwithstanding anything to the contrary contained herein, the
provisions of subsection (c) shall not apply with regard to any equitable
remedies to which any party may be entitled hereunder.

           The parties hereto (i) hereby irrevocably submit to the jurisdiction
of the United States District Court for the District of New Hampshire, for the
purpose of enforcing the award or decision in any such proceeding and (ii)
hereby waive, and agree not to assert, by way of motion, as a defense, or
otherwise, in any such suit, action or proceeding, any claim that it is not
subject personally to the jurisdiction of the above-named courts, that its

                                       6

<PAGE>

property is exempt or immune from attachment or execution, that the suit, action
or proceeding is brought in an inconvenient forum, that the venue of the suit,
action or proceeding is improper or that this Agreement or the subject matter
hereof may not be enforced in or by such court, and (iii) hereby waive and agree
not to seek any review by any court of any other jurisdiction which may be
called upon to grant an enforcement of the judgment of any such court. The
parties hereto hereby consent to service of process by registered mail at the
address to which notices are to be given. Each of the Company and Manager agrees
that its submission to jurisdiction and its consent to service of process by
mail is made for the express benefit of the other parties hereto. Final judgment
against the Company or Manager in any such action, suit or proceeding may be
enforced in other jurisdictions by suit, action or proceeding on the judgment,
or in any other manner provided by or pursuant to the laws of such other
jurisdiction; provided, however, that any party may at its option bring suit, or
institute other judicial proceedings, in any state or federal court of the
United States or of any country or place where the other parties or their
assets, may be found.

           The losing party shall bear all of the expenses incurred by both
parties in connection with any arbitration, including legal and other expenses,
unless the neutral advisor determines that it is appropriate for the parties to
share all or any part of the expenses incurred in connection with the
arbitration and the legal and other expenses, provided that any costs incurred
by a party to enforce an award of the neutral advisor pursuant to the foregoing
terms of this subsection (c) shall be borne by the parry resisting enforcement.

           12. Notices. All notices, requests, demands and other communications
provided for by this Agreement must be in writing and will be deemed to have
been given at the time when hand delivered or mailed in any general or branch
