Rabbi Trust Agreement, effective January 1, 2003, between the Registrant and Boston Safe Deposit Trust Company

Establishment of Trust.

The Company hereby establishes the Trust with the Trustee, consisting of such sums of money and other property acceptable to the Trustee as from time to time shall be paid and delivered to and accepted by the Trustee from the Company (the “Trust Fund”). The Trustee shall have no duty to determine or collect contributions under the Plan and shall have no responsibility for any property until it is received and accepted by the Trustee. The Company shall have the sole duty and responsibility for the determination of the accuracy or sufficiency of the contributions to be made under the Plan.

The Trust hereby established shall be irrevocable; notwithstanding the fact that the Trust is irrevocable, the Company may terminate the Plan (or any of them) at any time.

The Trust is intended to be a grantor trust, of which the Company is the grantor, within the meaning of subpart E, part I, subchapter J, chapter 1, subtitle A of the Internal Revenue Code of 1986, as amended, and shall be construed accordingly. The Company represents and warrants to the Trustee that: (i) the Plan for which benefits are or may become payable under this Trust is not subject to Part 4 of Title I of ERISA; and (ii) the Plan covers, and will cover, only (x) a select group of management or highly compensated employees as contemplated by Section 401(a) of ERISA and interpretations, opinions, and rulings of the Department of Labor thereunder or (y) participants in an excess benefit plan as defined in Section 3(36) of ERISA.

The principal of the Trust, and any earnings thereon shall be held separate and apart from other funds of the Company and shall be used exclusively for the purposes of paying Participants under the Plan, expenses of the Trust and, in the event of Insolvency, obligations of the Company to its general creditors as herein set forth. The Participants and their beneficiaries shall have no preferred claim on, nor any beneficial ownership interest in, any assets of the Trust. Any rights created under the Plan and this Rabbi Trust Agreement shall be unsecured contractual rights of the Participants and their beneficiaries against the Company. Any assets held by the Trust will be subject to the claims of the Company’s general creditors under federal and state law in the event of Insolvency, as defined in Section 4(a) herein.

In addition to the contributions necessary to meet the Trust Funding Requirement (as defined in Section 2), the Company, in its sole discretion, may at any time, or from time to time, make additional deposits of cash or other property in trust with the Trustee to augment the principal to be held, administered and disposed of by the Trustee as provided in this Rabbi Trust Agreement. Neither the Trustee nor any Participant or beneficiary shall have any right to compel such additional deposits.

Trust Funding Requirement.

Payments to Plan Participants and Their Beneficiaries.

The Company shall deliver to the Trustee a schedule (the “Payment Schedule”) that indicates the amounts payable in respect of each Participant (and his or her beneficiaries), and that provides a formula or other instructions acceptable to the Trustee for determining the amounts so payable, the form in which such amount is to be paid (as provided for or available under the Plan), and the time of commencement for payment of such amounts. The Company shall be responsible for notifying the Trustee of any change in the information on the Payment Schedule. Except as otherwise provided herein, the Trustee shall make payments to the Participants and their beneficiaries in accordance with such Payment Schedule.

The entitlement of a Participant or his or her beneficiaries to benefits under the Plan shall be determined by the Company or such party as it shall designate under the Plan, and any claim for such benefits shall be considered and reviewed under the procedures set out in the Plan. The Company shall notify the Trustee of such determination and shall direct commencement of payments of such benefits.

The Company may make payment of benefits directly to the Participants or their beneficiaries as they become due under the terms of the Plan. The Company shall notify the Trustee of its decision to make payment of benefits directly prior to the time amounts are payable to Participants or their beneficiaries. If requested by the Company, the Trustee shall reimburse the Company for any benefits under the Plan and Trust which are paid by the Company or otherwise satisfied. In addition, if the principal of the Trust, together with any earnings thereon, are not sufficient to make payment of benefits in accordance with the terms of the Plan, the Company shall immediately make up the balance of each such payment as it falls due. The Trustee shall notify the Company when principal and earnings are not sufficient.

Trustee Responsibility regarding Payments to Trust Beneficiary When Company Is or Is Alleged to Be Insolvent.

The Trustee shall cease payment of benefits to the Participants and their beneficiaries if the Company is Insolvent. The Company shall be considered “Insolvent” for purposes of this Rabbi Trust Agreement if (i) the Company is unable to pay its debts as they become due, or (ii) the Company is subject to a pending proceeding as a debtor under the United States Bankruptcy Code. A determination of Insolvency under the terms of this Rabbi Trust Agreement does not constitute an admission of insolvency by the Company for any other purpose.

At all times during the continuance of this Trust, as provided in Section 1(d) hereof, the principal and income of the Trust shall be subject to claims of general creditors of the Company under federal and state law as set forth below.

The Board of Directors and the Chief Executive Officer of the Company shall have the duty to inform the Trustee in writing of the Company’s Insolvency. If a person claiming to be a creditor of the Company alleges in writing to the Trustee that the Company has become Insolvent, the Trustee shall determine whether the Company is Insolvent and, pending such determination, the Trustee shall discontinue payment of benefits to the Participants or their beneficiaries. In all cases, the Trustee shall be entitled to conclusively rely upon the written certification of the Board of Directors or the Chief Executive Officer of the Company when determining whether the Company is Insolvent.

Unless the Trustee has received notice from the Company or a person claiming to be a creditor alleging that the Company is Insolvent, the Trustee shall have no duty to inquire whether the Company is Insolvent. The Trustee may in all events rely on such evidence concerning the Company’s solvency as may be furnished to the Trustee and that provides the Trustee with a reasonable basis for making a determination concerning the Company’s solvency.

If at any time the Trustee has determined that the Company is Insolvent, the Trustee shall discontinue payments to the Participants or their beneficiaries and shall hold the assets of the Trust for the benefit of the Company’s general creditors except that the Trustee’s fees and expenses may continue to be paid pursuant to Section 11 subject to any applicable bankruptcy rules. Nothing in this Rabbi Trust Agreement shall in any way diminish any rights of the Participants or their beneficiaries to pursue their rights as general creditors of the Company with respect to benefits due under the Plan or otherwise.

The Trustee shall resume the payment of benefits to the Participants or their beneficiaries in accordance with Section 3 of this Rabbi Trust Agreement only after the Trustee has determined that the Company is not Insolvent (or is no longer Insolvent).

Provided that there are sufficient assets if the Trustee discontinues the payment of benefits from the Trust pursuant to Section 4(b) hereof and subsequently resumes such payments, the first payment following such discontinuance shall include the aggregate amount of all payments due to the Participants or their beneficiaries under the terms of the Plan (as certified to the Trustee by the Company) for the period of such discontinuance less the aggregate amount of any payments made to the Participants or their beneficiaries by the Company in lieu of the payments provided for hereunder during any such period of discontinuance.

Payments to Company.

Investment and Administrative Authority.

Prior to a Change of Control the Company shall establish and maintain written investment guidelines (the “Investment Guidelines”), which may be revised by the Company from time to time, for the investment of the assets in the Trust Fund. The Trust Fund shall at all times be managed in accordance with the Investment Guidelines then in effect. The Company may appoint and remove one or more investment managers from time to time to manage specified portions of the Trust Fund. To the extent that assets of the Trust Fund are not so managed by an investment manager appointed by the Company, the Company shall manage all such assets. The Company and each investment manager shall designate in writing the persons who are authorized to represent such party in dealing with the Trustee. Except as provided in subsection (b) below, the Trustee shall have no investment duties for the Trust Fund. The Trustee shall have no duty to inquire whether investment directions received from the Company or an investment manager are in accordance with the Plan or the Investment Guidelines, or to review the assets purchased, retained or sold.

After a Change of Control, the Trustee shall have and exercise sole investment discretion with respect to all of the Trust Fund in accordance with the Investment Guidelines in effect immediately prior to a Change of Control, a copy of which shall be provided prior to a Change of Control to the Trustee by the Company. The Trustee’s sole responsibility with regard to investment discretion shall be to exercise such

The Company shall have the right at any time, and from time to time, in its sole discretion, to substitute assets of equal fair market value for any asset held by the Trust. This right is exercisable by Company in a non-fiduciary capacity without the approval or consent of any person in a fiduciary capacity.

In addition to those powers conferred by law, the Trustee shall have the following powers:

The Trustee may invest and reinvest the principal and income of the Trust and keep it invested, without distinction between principal and income, in any security or property pursuant to the direction of the Company or an investment manager appointed by the Company prior to a Change of Control and in the Trustee’s sole discretion after a Change of Control; provided, however, that in no event may the Trustee invest in securities (including stock or rights to acquire stock) or obligations issued by the Company, other than a de minimis amount held in common investment vehicles in which the Trustee invests. Also, in no event shall the Trust be invested in real estate. For this purpose, “real estate” includes, but is not limited to, real property, leaseholds, mineral interests, and any form of assets which is secured by any of the foregoing. All rights associated with assets of the Trust shall be exercised by the Trustee or the person designated by the Trustee, and shall in no event be exercisable by or rest with the Participants.

The Trustee may collect and receive any and all money and other property due the Trust and give full discharge therefor.

The Trustee may deposit cash into interest bearing accounts in the banking department of the Trustee or an affiliated banking organization;

The Trustee may purchase, enter, sell, hold, and generally deal in any manner in and with contracts for the immediate or future delivery of financial instruments of any issuer or of any other property and may also grant, purchase, sell, exercise, permit to expire, permit to be held in escrow, or otherwise acquire, dispose of, hold and generally deal in any manner with and in all forms of options or any combination thereof pursuant to the direction of the Company or an investment manager appointed by the Company prior to a Change of Control, and in the Trustee’s sole discretion after a Change of Control provided that such investments are in accordance with the Investment Guidelines.

The Trustee may settle, compromise or submit to arbitration any claims, debt or damages due or owing to or from the Trust; the Trustee may also commence or defend suits or legal proceedings to protect any interest of the Trust, and may represent the Trust in all suits or legal proceedings in any court or before any other body or tribunal.

The Trustee may take all action necessary to pay for authorized transactions, including the temporary advancement of cash or securities to settle security purchases and/or foreign exchange or contracts for foreign exchange and any property at any time held in the Trust Fund shall be security therefore to the extent of such advancement until it is repaid.

The Trustee may appoint custodians, subcustodians or subtrustees, domestic or foreign (including affiliates of the Trustee), as to part or all of the Trust. The Trustee shall not be responsible or liable for any losses or damages suffered by the Company arising as a result of the insolvency of any custodian, subcustodian or subtrustee, except to the extent the Trustee was negligent in its selection or continued retention of such custodian, subcustodian or subtrustee. In no event shall Trustee be liable for the acts or omissions of any custodian, subcustodian or subtrustee appointed pursuant to the direction of the Company or an investment manager.

The Trustee may hold property in nominee name, in bearer form, or in book entry form, in a clearinghouse corporation or in a depository (including an affiliate of the Trustee), so long as the Trustee’s records clearly indicate that the assets held are a part of the Trust. The Trustee shall not be responsible for any losses resulting from the deposit or maintenance of securities or other property (in accordance with market practice, custom, or regulation) with any recognized foreign or domestic clearing facility, book-entry system, centralized custodial depository, or similar organization.

The Trustee may generally do all acts, whether or not expressly authorized, which the Trustee may deem necessary or desirable for the protection of the Trust.

Settlement and Income; Market Practice Settlements.

In accordance with the Trustee’s standard operating procedure, the Trustee shall credit the Trust Fund with income, which shall include interest, dividends and return of capital, and maturity proceeds on securities on contractual payment date net of any taxes or upon actual receipt. To the extent the Trustee credits income on contractual payment date, the Trustee may reverse such accounting entries to the contractual payment date if the Trustee reasonably believes that such amount will not be received.

In accordance with the Trustee’s standard operating procedure, the Trustee will attend to the settlement of securities transactions on the basis of either contractual settlement date accounting or actual settlement date accounting. To the extent the Trustee settles certain securities transactions on the basis of contractual settlement date accounting, the Trustee may reverse to the contractual settlement date any entry relating to such contractual settlement if the Trustee reasonably believes that such amount will not be received.

Settlements of transactions may be effected in trading and processing practices customary in the jurisdiction or market where the transaction occurs. The Company acknowledges that this may, in certain circumstances, require the delivery of cash or securities (or other property) without the concurrent receipt of securities (or other property) or cash. In such circumstances, the Trustee shall have no responsibility for nonreceipt of payment (or late payment) or nondelivery of securities or other property (or late delivery) by the counterparty.

Disposition of Income.

Accounting by Trustee.

Responsibility of Trustee.

The Trustee shall act with the care, skill, prudence and diligence under the circumstances then prevailing that a prudent person acting in like capacity and familiar with such matters would use in the conduct of an enterprise of a like character and with like aims, provided, however, that the Trustee shall incur no liability to any person for any action taken pursuant to a direction, request or approval given by the Company which is contemplated by, and in conformity with, the terms of the Plan (as certified to the Trustee by the Company) or this Trust and is given in writing by the Company. In the event of a dispute between the Company and a third party, the Trustee may apply to a court of competent jurisdiction to resolve the dispute.

The Trustee is not a party to and has no duties or responsibilities under the Plan other than those that may be expressly contained in this Rabbi Trust Agreement. In any case in which a provision of this Rabbi Trust Agreement conflicts with any provision in the Plan, this Rabbi Trust Agreement shall control.

The Trustee shall not be responsible for the title, validity or genuineness of any property or evidence of title thereto received by it or delivered by it pursuant to this Rabbi Trust Agreement and shall be held harmless in acting upon any notice, request, direction, instruction, consent, certification or other instrument believed by it to be genuine and delivered by the proper party or parties.

The Company agrees to indemnify and hold harmless the Trustee, its parent, subsidiaries and affiliates, and each of their respective officers, directors, employees and agents from and against all liability, loss and expense, including reasonable attorneys’ fees and expenses incurred by the Trustee or any of the foregoing indemnitees arising out of or in connection with this Rabbi Trust Agreement, except as a result of the Trustee’s own negligence, willful misconduct, bad faith or breach of this Agreement or of its fiduciary duties . The Trustee shall be fully indemnified by the Company for any action taken in accordance with, or any failure to act in the absence of, the Company’s or an investment manager’s directions. If the Trustee undertakes or defends any litigation arising in connection with this Trust, the Company agrees to indemnify the Trustee against the Trustee’s costs, expenses and liabilities (including, without limitation, attorneys’ fees and expenses) relating thereto and to be primarily liable for such payments except where the Trustee is determined to be liable due to its negligence, willful misconduct, bad faith, or breach of this Rabbi Trust Agreement or of its fiduciary duties. If the Company does not pay such costs, expenses and liabilities in a reasonably timely manner, the Trustee may obtain payment from the Trust. This Section 10(d) shall survive the termination of this Rabbi Agreement.

The Trustee may consult with legal counsel (who may also be counsel for the Company generally) with respect to any of its duties or obligations hereunder and as a part of its reimbursable expenses under this Agreement, pay counsel’s reasonable compensation and expenses. The Trustee shall be entitled to rely on and may act upon advice of counsel on all matters, and shall be without liability for any action reasonably taken or omitted pursuant to such advice.

The Trustee may hire agents, accountants, actuaries, investment advisors, financial consultants or other professionals, including affiliates, to assist it in performing any of its duties or obligations hereunder.

The Trustee shall have without exclusion, all powers conferred on Trustees by applicable law, unless expressly provided otherwise herein, provided, however, that if an insurance policy is held as an asset of the Trust, the Trustee shall have no power to name a beneficiary of the policy other than the Trust, to assign the policy (as distinct from conversion of the policy to a different form) other than to a successor Trustee, or to loan to any person the proceeds of any borrowing against such policy.

Notwithstanding any powers granted to the Trustee pursuant to this Trust Agreement or to applicable law, the Trustee shall not have any power that could give this Trust the objective of carrying on a business and dividing the gains therefrom, within the meaning of Section  ###-###-####-2 of the Procedure and Administrative Regulations promulgated pursuant to the Internal Revenue Code.

Notwithstanding anything in this Rabbi Trust Agreement to the contrary contained herein, the Trustee shall not be responsible or liable for any losses to the Trust resulting from any event beyond the reasonable control of the Trustee, its agents or custodians, including but not limited to nationalization, strikes, expropriation, devaluation, seizure, or similar action by any governmental authority, de facto or de

The Trustee shall not be liable for any act or omission of any other person, except to the extent that such person is an agent of the Trustee (not appointed pursuant to the direction of the Company or an investment manager) or under the control of the Trustee, in carrying out any responsibility imposed upon such person and under no circumstances shall the Trustee be liable for any indirect, consequential, or special damages with respect to its role as Trustee.
