(b) The Trust also agrees, subject to the provisions of Section 12 hereof, to pay all costs of the Agent incurred with respect to the collection of any of the Obligations and the enforcement of any Secured Parties' rights hereunder, including all costs and expenses of every kind incurred therein or incidental to the care, safekeeping or otherwise of any or all of the Collateral, and attorneys' fees and expenses.

To the extent that it lawfully may, the Trust hereby agrees that it will not invoke any law relating to marshalling of collateral which might cause delay in or impede the enforcement of the Secured Parties' rights under this Agreement, or under any other instrument evidencing any of the Obligations or under which any of the Obligations is outstanding or by which any of the Obligations is secured or guaranteed, and to the extent that it lawfully may, the Trust hereby irrevocably waives the benefits of all such laws. Section 10. Concerning Agent; Appointment of Agent; Limitation on Agent's Duty in Respect of Collateral. (a) The institution and/or person acting as Trustee, by its execution of the requisite documents pursuant to which it accepted its appointment as successor trustee under the Trust Agreement, has thereby acknowledged and agreed that its beneficial interest in the security interest granted to the Agent under this Security Agreement shall be in lieu of all other liens on the Trust Estate (which may arise as a matter of law or otherwise) in favor of such institution and/or person, and does thereby expressly waive the benefits of any such lien. (b) Subject to the provisions of paragraph (c) of this Section 10, the Agent shall, upon the written instruction of the Majority Banks, promptly take or refrain from taking any action, or consent or effect a modification, waiver, alteration or amendment of this Security Agreement, or exercise or refrain from exercising any right, granted to the Agent, for the ratable benefit of the Secured Parties, under this Security Agreement, provided, however, that no individual Bank (other than the Agent) or the Trust shall have any right to enforce directly any of the rights or the security interests granted by this Security Agreement or to require the Agent to take or refrain from taking any action under this Security Agreement. (c) The Agent shall not be required to do any acts hereunder or to take any action toward the execution or enforcement of the agency hereby created or to prosecute or defend any suit in respect of this Agreement or any instrument delivered hereunder or otherwise, unless indemnified to its satisfaction by the Banks (to the extent not indemnified therefor by the Trust) against loss, cost, liability and expense. If any indemnity furnished to the Agent for any purpose, in the reasonable judgment of the Agent determined in good faith, shall be insufficient or shall become impaired, the Agent may call for additional indemnity and shall not be required to commence, or shall be entitled to cease, to do the acts indemnified against unless such additional indemnity has been furnished. (d) The Agent agrees, for the benefit of the Secured Parties, that it will, subject to paragraph (c) of this Section 10, enforce the rights and security interests granted to the Secured Parties hereunder, in accordance with written instructions given pursuant to paragraph (b) of this Section 10, with the same degree of care which it would exercise in secured transactions for its own account. The Agent may exercise its powers and execute its duties by or through employees or agents and shall be entitled to take, and to rely on, advice of counsel concerning all matters pertaining to its rights and duties under this Agreement. Neither the Agent nor any of its shareholders, directors, officers or employees shall be liable to the Secured Parties for any action taken, or omitted to be taken, in good faith by it or them hereunder or in connection herewith or be responsible for the consequences of any oversight or error of judgment, provided that the Agent may be liable for losses due to its gross negligence or willful misconduct. Notwithstanding any other provision of this Security Agreement, neither the Agent nor any of its shareholders, directors, officers or employees shall be liable to the Secured Parties for any action taken, or omitted to be taken, in accordance with written instructions of the Majority Banks pursuant to paragraph (b) of this Section 10, and in accordance with the standard of care required by this paragraph (d). (e) The Agent will not be responsible to the Secured Parties for any recitals or statements, warranties or representations in the Credit Agreement or this Security Agreement or made in any certificate or instrument hereafter furnished to it by or on behalf of any of the other parties to the Credit Agreement or this Security Agreement or be bound to ascertain or inquire as to the performance or observance of any of the terms, conditions, covenants or agreements therein. The Agent makes no representations or warranties, and assumes no responsibility to the Secured Parties, with respect to the legality, sufficiency, enforceability or collectibility of the Credit Agreement or this Security Agreement or any agreement, instrument or other document referred to in any such documents, or of any Collateral, or of the financial condition of the Trust or the Company. The Agent assumes no responsibility for the security value of the Collateral, or for the performance of any obligations of the Trust or the Company. Beyond the safe custody thereof, the Agent shall not have any duty as to any Collateral in its possession or control or in the possession or control of any of its agents or nominees or any income thereon or as to the preservation of rights against prior parties or any other rights pertaining thereto. (f) For all purposes of this Security Agreement, in absence of actual knowledge of a responsible officer of the Agent, the Agent shall not be deemed to have knowledge of any Default or Event of Default unless or until so notified in writing by the Trust or the Company. Section 11. Application of Proceeds Upon Event of Default. Any monies or property actually received by the Agent pursuant to the exercise of any rights or remedies referred to in Section 9 or 11 hereof or otherwise, upon the occurrence of an Event of Default, shall be applied in the following order: first, to the payment of all amounts due to the Agent under Sections 8, 9 and 10(b) of this Security Agreement and applicable law; second, ratably, to the payment of any amounts then due and payable to any Secured Party under the Credit Agreement and the Notes, according to the then unpaid amounts thereof, without preference or priority of any kind among them (such payment in each case, to be applied first to accrued unpaid interest and, thereafter, to unpaid principal debt); third, ratably, to the payment of amounts, if any, then due and owing to any Secured Party (including the Agent) on account of any indemnifications pursuant to this Security Agreement, the Trust Agreement or any Contract, and to the payment of amounts then due and payable to the institution acting as Trustee on account of obligations for fees or expenses arising under the Trust Agreement according to the then unpaid amounts thereof, without preference or priority of any kind among them; fourth, ratably, to the payment of all of the Obligations (except for Obligations which shall have been paid pursuant to items first, second or third of this Section 11), according to the then unpaid amounts thereof, without preference or priority of any kind among them; and fifth, the remainder, if any, to the Trust, its successors or assigns, or to whomsoever may be lawfully entitled to receive the same, or as a court of competent jurisdiction may direct. Section 12. Concerning Trustee. (a) State Street Bank and Trust Company in its capacity as Trustee, is entering into this Security Agreement and granting the security interest provided for herein solely as successor trustee under the Trust Agreement and pursuant to instructions contained therein, and not in its individual capacity and in no case whatsoever shall State Street Bank and Trust Company (or any entity acting as a successor trustee, co-trustee or separate trustee under the Trust Agreement) be personally liable on, or for any loss in respect of, any of the statements, representations, warranties, agreements or obligations of the Trustee hereunder or for any losses the Trust may suffer, as to all of which the Agent, on behalf of the Secured Parties, agrees to look solely to the Trust, except for any loss caused by the Trustee's willful misconduct or gross negligence (provided that this exception shall not be deemed to apply to the extent that the Trustee has followed instructions given to it, or which it is authorized to accept, pursuant to this Agreement and the Trust Agreement). (b) The Agent, on behalf of the Secured Parties, agrees that if any other successor trustee is appointed in accordance with the terms of the Trust Agreement, such successor trustee shall, without further act, succeed to all the rights, duties, immunities and obligations of the Trustee hereunder and the predecessor successor trustee shall be released from all further duties and obligations hereunder, all without in any way altering the terms of this Security Agreement or the Trustee's obligations hereunder. Section 13. Release of Collateral. The Agent, on behalf of the Secured Parties, agrees that each time the Trust is required by the terms of the Fuel Purchase Contract to transfer title to any Commodities to the Company free and clear of the security interest created by this Security Agreement, the Agent, on behalf of the Secured Parties, shall release its security interest so that such transfer may be made; provided that (i) no Default or Event of Default has occurred and is continuing, and the Trustee and the Company shall have delivered a certificate to such effect in the form of Annex III attached hereto, signed by a duly authorized officer of the Trustee and the Company (it being understood that the Trustee shall be entitled to rely on the representations of the Company in such certificate with respect to the matters therein except to the extent that the Trustee has received notice or has actual knowledge of such matters) upon which the Agent shall be entitled to rely, (ii) the Company and the Trust have each complied to the satisfaction of the Agent with all provisions of the Fuel Purchase Contract relating to such transfer, (iii) any payment required to be made by the Company in connection with such transfer shall have been deposited in the Cash Collateral Account, and (iv) any Collateral being substituted for such Commodities shall have become subject to the security interest created by this Security Agreement and such security interest shall have been perfected.

Any notice to the Agent or the Trust hereunder shall be deemed to have been duly given when delivered or when deposited in the mail, first class postage prepaid, addressed: if to the Agent, at One Federal Street, Boston, Massachusetts 02211, Attention: Thomas L. Rose, Vice President, National Utilities Group, and if to the Trust, at State Street Bank and Trust Company, Two International Place, Boston, Massachusetts 02110, Attention: Virginia Jones, Secretary. Section 15. Severability. Any provision of this Security Agreement which is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction. Section 16. No Waiver; Cumulative Remedies; Amendments. The Agent or any other Secured Party shall not by any act, delay, omission or otherwise be deemed to have waived any of its rights or remedies hereunder and no waiver shall be valid unless in writing, signed by the Agent on behalf of the Secured Parties, and then only to the extent therein set forth. A waiver by the Agent on behalf of the Secured Parties of any right or remedy hereunder on any one occasion shall not be construed as a bar to any right or remedy which the Agent or any other Secured Party would otherwise have had on any future occasion. No failure to exercise nor any delay in exercising on the part of the Agent or any other Secured Party, any right, power or privilege hereunder, shall operate as a waiver thereof, nor shall any single or partial exercise of any right, power or privilege hereunder preclude any other or further exercise thereof or the exercise of any other right, power or privilege. The rights and remedies hereunder provided are cumulative and may be exercised singly or concurrently, and are not exclusive of any rights and remedies provided by law. None of the terms or provisions of this Security Agreement may be waived, altered, modified or amended except by an instrument in writing, duly executed by the party sought to be bound thereby. Section 17. Successors and Assigns; Governing Law. This Security Agreement and all obligations of the Trust hereunder shall be binding upon the successors and assigns of the Trust, and shall inure to the benefit of the Agent and the other Secured Parties and each of their respective successors and assigns, subject to the limitations on the right of assignment contained in Section 18 of the Credit Agreement. This Security Agreement shall be governed by, and be construed and interpreted in accordance with, the laws of The Commonwealth of Massachusetts, without regards to principles of conflicts of law.
