(a) Beyond its duties set forth in this Agreement as to the custody thereof and the accounting to the Trustors and the Holders for moneys received by it hereunder, the Collateral Agent shall not have any duty to the Trustors and the Holders as to any Collateral in its possession or control or in the possession or control of any agent or nominee of it or any income thereon or as to the preservation of rights against prior parties or any other rights pertaining thereto. To the extent, however, that the Collateral Agent or any agent or nominee thereof maintains possession or control of any of the Collateral, the Collateral Agent shall, and shall instruct such agent or nominee to, grant the Trustors access to such Collateral that the Trustors require for the normal conduct of their business, consistent with their current practice so long as the Collateral Agent shall not have received a Notice of Actionable Default.

(b) The powers conferred on Collateral Agent hereunder are solely to protect its interest in the Collateral and shall not impose any duty upon it to exercise any such powers. Except for the exercise of reasonable care in the custody of any Collateral in its possession and the accounting for moneys actually received by it hereunder, Collateral Agent shall have no duty as to any Collateral or as to the taking of any necessary steps to preserve rights against prior parties or any other rights pertaining to any Collateral. Collateral Agent shall be deemed to have exercised reasonable care in the custody and preservation of Collateral in its possession if such Collateral is accorded treatment substantially equal to that which Collateral Agent accords its own property. Neither Collateral Agent nor any of its directors, officers, employees or agents shall be liable for failure to demand, collect or realize upon all or any part of the Collateral or for any delay in doing so or shall be under any obligation to sell or otherwise dispose of any Collateral upon the request of any Grantor or otherwise.

3.12 Limitation by Law.

All rights, remedies and powers provided by this Section 3 may be exercised only to the extent that the exercise thereof does not violate any applicable provision of law in the premises, and all the provisions of this Section 3 are intended to be subject to all applicable mandatory provisions of law that may be controlling in the premises and to be limited to the extent necessary so that they will not render this Agreement invalid, unenforceable in whole or in part or not entitled to be recorded, registered, or filed under the provisions of any applicable law.

3.13 Absolute Rights of Holders.

Notwithstanding any other provision of this Agreement (other than Section 3.2) or any provision of any Collateral Document, but subject to the provisions of the Indenture, the right of each Holder, which is absolute and unconditional, to receive payments of the Secured Obligations held by such

Holder on or after the due date thereof as therein expressed, to seek adequate protection in respect of its interest in this Agreement and the Collateral, to institute suit for the enforcement of such payment on or after such due date, or to assert its position and views as a secured creditor in a Bankruptcy Proceeding, or the obligation of the Trustors, which is also absolute and unconditional, to pay the Secured Obligations to the Holders at the time and place expressed therein shall not be impaired or affected without the consent of such Holder.

SECTION 4

Trust Account, Application Of Moneys.

4.1 The Trust Account.

On the date hereof there shall be established and, at all times thereafter until the trusts created by this Agreement shall have terminated, there shall be maintained with the Collateral Agent an account that shall be entitled the “Evergreen Solar, Inc.

All moneys that are received by the Collateral Agent after the occurrence of an Actionable Default in respect of the Collateral shall be deposited in the Trust Account and thereafter shall be held and applied by the Collateral Agent in accordance with the terms of this Agreement and the Indenture. To the extent necessary, appropriate or desirable, the Collateral Agent from time to time may establish sub-accounts as part of the Trust Account for the purpose of better identifying and maintaining proceeds of Collateral, all of which sub-accounts shall be treated as and be deemed equivalent to, the Trust Account for all purposes hereof.

4.2 Control of Trust Account.

All right, title and interest in and to the Trust Account shall vest in the Collateral Agent, and funds on deposit in the Trust Account shall constitute part of the Trust Estate. The Trust Account shall be subject to the exclusive dominion and control of the Collateral Agent.

4.3 Investment of Funds Deposited in Trust Account.

(a) All monies received by the Collateral Agent shall, until used or applied as herein provided, be held in trust for the purposes for which they were received, but need not be segregated in any manner from any other moneys, except to the extent required by law, and may be deposited by the Collateral Agent under such general conditions as may be prescribed by law in the Collateral Agent’s general banking department, and the Collateral Agent shall be under no liability for interest on any moneys received by it hereunder.

(b) The Collateral Agent may invest funds on deposit in the Trust Account in Permitted Investments. “Permitted Investments” means such investments as may be specified from time to time by written instruction from the Company, which instructions may be given only if an Event of Default does not then exist; provided, such investments are consistent with the Collateral Agent’s investment criteria, including without limitation, direct obligations of the United States government having maturities of 90 days or less, money market deposit accounts with United States banks, which may include the Collateral Agent, whose short-term debt ratings are not less than A-1/P-1, money market funds that invest solely in direct obligations of the United States government and repurchase agreements. The Collateral Agent or any of its affiliates may receive compensation with respect to any investment

directed hereunder. The Collateral Agent will act upon investment instructions the day that such instructions are received, provided that the requests are communicated within a sufficient amount of time to allow the Collateral Agent to make the specified investment. Instructions received after an applicable investment cutoff deadline will be treated as being received by the Collateral Agent on the next business day, and the Collateral Agent shall not be liable for any loss arising directly or indirectly, in whole or in part, from the inability to invest funds on the day the instructions are received. The Collateral Agent shall not be liable for any loss incurred by the actions of third parties or for any loss arising by error, failure or delay in the making of an investment or reinvestment, and the Collateral Agent shall not be liable for any loss of principal or income in connection therewith, unless such error, failure or delay results from the Collateral Agent’s gross negligence or willful misconduct. The Collateral Agent shall not be liable for any loss of principal or income due to the choice of Permitted Investments in which any moneys received by it hereunder are invested or the choice of Permitted Investments converted into cash pursuant to this Section 4.3(b).

(c) All such investments and the interest and income received thereon and therefrom and the net proceeds realized on the sale thereof shall be held in the Trust Account, as applicable, as part of the Trust Estate. The parties acknowledge that, for tax reporting purposes, all interest attributable to the Trust Account pursuant to this Agreement shall be allocable to the Company.

4.4 Application of Moneys in Trust Account.

Subject to Section 4.5, all moneys held by the Collateral Agent in the Trust Account shall, to the extent available for distribution, be distributed (or deposited in a separate account for the benefit of the Trustee pursuant to Section 4.5) by the Collateral Agent as follows:

First: To the Collateral Agent in an amount equal to the Collateral Agent’s Fees that are unpaid as of the relevant Distribution Date and to any Secured Party that has theretofore advanced or paid any such Collateral’s Fees in an amount equal to the amount thereof so advanced or paid by such Secured Party prior to such Distribution Date;

Second: The Trustee for application to the payment in full of all outstanding Secured Obligations, whether or not due and payable to the Secured Parties (which shall then be applied or held by the trustee in such order as may be provided in the Indenture); and

Third: Any surplus then remaining shall be paid to the respective Trustor, its successors or assigns, or to whomsoever may be lawfully entitled to receive the same, or as a court of competent jurisdiction may direct.

4.5 Application of Moneys Distributable to Holders of Notes.

If at any time any moneys collected or received by the Collateral Agent pursuant to this Agreement or any Collateral Document are distributable pursuant to Section 4.4 to the Trustee, and if the Trustee shall notify the Collateral Agent that no provision is made under the Indenture (i) for the application by the Trustee of such amounts so distributable (whether by virtue of the respective Notes issued under the Indenture not having become due and payable or otherwise) or (ii) for the receipt and the holding by the Trustee of such amounts pending the application thereof, then the Collateral Agent shall invest all such amounts applicable to Holders of Notes in obligations of the kinds referred to in Section 4.3, and shall hold all such amounts so distributable, and all such investments and the proceeds thereof, in

trust solely for the Trustee and for no other purpose until such time as the Trustee shall request the delivery thereof by the Collateral Agent to the Trustee for application by it pursuant to Indenture.

This Section 4 is intended for the benefit of, and will be enforceable as a third party beneficiary by, each present and future holder of Secured Obligations, each present and future Trustee, and the Collateral Agent as a Secured Party.

The Collateral Agent makes no representations as to the value or condition of the Trust Estate or any part thereof, or as to the title of the Trustors thereto or as to the security afforded by any Collateral Document or this Agreement, or as to the validity, execution (except its own execution), enforceability, legality or sufficiency of this Agreement, any Collateral Document or the Secured Obligations secured hereby and thereby, and the Collateral Agent shall incur no liability or responsibility in respect of any such matters. The Collateral Agent shall not be responsible for insuring the Trust Estate or for the payment of taxes, charges, assessments or liens upon the Trust Estate or otherwise as to the maintenance of the Trust Estate, except that in the event the Collateral Agent enters into possession of a part or all of the Trust Estate, the Collateral Agent shall preserve the part in its possession.

(b) The Collateral Agent shall not be required to ascertain or inquire as to the performance by the Trustors of any of the covenants or agreements contained herein, in any Collateral Document or in any other Note Document.

(c) The Collateral Agent shall not be personally liable for any action taken or omitted to be taken by it in accordance with this Agreement or any Collateral Document except for its own gross negligence or willful misconduct.

(d) The Collateral Agent shall have no responsibility for the preparation, filing or recording of any instrument, document or financing statement or for the maintenance of any security interest intended to be perfected thereby.

The Collateral Agent may execute any of the trusts or powers hereof and perform any duty hereunder either directly or by or through agents or attorneys-in-fact, which may include officers and employees of the Trustors. The Collateral Agent shall be entitled to advice of counsel concerning all matters pertaining to such trusts, powers and duties. The Collateral Agent shall not be responsible for the negligence or misconduct of any agents or attorneys-in-fact selected by it without gross negligence or willful misconduct.

6.4 Reliance by Collateral Agent.

(a) Whenever in the administration of the trusts of this Agreement the Collateral Agent shall deem it necessary or desirable that a matter be proved or established in connection with the taking, suffering or omitting any action hereunder by the Collateral Agent, such matter (unless other evidence in respect thereof be herein specifically prescribed) may be deemed to be conclusively provided or established by a certificate of a Responsible Officer of any Trustor delivered to the Collateral Agent, and such certificate shall be full warranty to the Collateral Agent for any action taken, suffered or omitted in reliance thereon, subject, however, to the provisions of Section 6.5.

(b) The Collateral Agent may consult with counsel, and any opinion of such counsel who is not an employee of the Collateral Agent shall be full and complete authorization and protection in respect of any action taken or suffered by it hereunder in accordance therewith. The Collateral Agent shall have the right at any time to seek instructions concerning the administration of the Trust Estate from any court of competent jurisdiction.

(c) The Collateral Agent may rely, and shall be fully protected in acting, upon any resolution, statement, certificate, instrument, opinion, report, notice, request, consent, order, bond or other paper or document that it has no reason to believe to be other than genuine and to have been signed or presented by the proper party or parties or, in the case of cables, telecopies and telexes, to have been sent by the proper party or parties. In the absence of its gross negligence or willful misconduct, the Collateral Agent may conclusively rely, as to the truth of the statements and the correctness of the opinions expressed therein, upon any certificates or opinions furnished to the Collateral Agent and conforming to the requirements of this Agreement or any Collateral Document.

(d) The Collateral Agent shall not be under any obligation to exercise any of the rights or powers vested in the Collateral Agent by this Agreement at the request or direction of the Majority Holders pursuant to this Agreement or any Collateral Document, unless the Collateral Agent shall have been provided adequate security and indemnity against the costs, expenses and liabilities that may be incurred by it in compliance with such request or direction, including such reasonable advances as may be requested by the Collateral Agent.

6.5 Limitations on Duties of Collateral Agent.

(a) The Collateral Agent shall be obliged to perform such duties and only such duties as are specifically set forth in this Agreement or in any Collateral Document, and no implied covenants or obligations shall be read into this Agreement or any Collateral Document against the Collateral Agent and the Collateral Agent shall not be liable with respect to any action taken or omitted by it in accordance with the direction of the Holders pursuant to Section 3.8.

(b) Except as herein otherwise expressly provided, the Collateral Agent shall not be under any obligation to take any action that is discretionary with the Collateral Agent under the provisions hereof or under any Collateral Document except upon the written request of the Holders pursuant to Section 3.8. The Collateral Agent shall make available for inspection and copying by the Trustee, each certificate or other paper furnished to the Collateral Agent by Company under or in respect of this Agreement, any Collateral Document or any of the Trust Estate.

6.6 Moneys to be Held in Trust.

All moneys received by the Collateral Agent under or pursuant to any provision of this Agreement or any Collateral Document shall be held in trust for the purposes for which they were paid or are held.

6.7 Resignation and Removal of the Collateral Agent.

(a) The Collateral Agent may at any time, by giving 30 days’ prior written notice to Company and the Trustee, resign and be discharged of the responsibilities hereby created, such resignation to become effective upon the earlier of: (i) 30 days from the date of such notice; and (ii) the appointment of a successor trustee or trustees by Company, the acceptance of such appointment by such successor trustee or trustees, and the approval of such successor trustee or trustees by the Majority Holders; provided, that, no resignation shall become effective unless and until a successor trustee has been appointed as provided herein. The Collateral Agent may be removed at any time and a successor trustee or trustees appointed by the affirmative vote of the Majority Holders; provided that the Collateral Agent shall be entitled to its fees and expenses to the date of removal. If no successor trustee or trustees shall be appointed and approved within 30 days from the date of the giving of the aforesaid notice of resignation the Collateral Agent shall, or the Trustee or any Holder may, apply to any court of competent jurisdiction to appoint a successor trustee or trustees (which may be an individual or individuals) to act until such time, if any, as a successor trustee or trustees shall have been appointed as above provided. Any successor trustee or trustees so appointed by such court shall immediately and without further act be superseded by any successor trustee or trustees approved by the Majority Holders as above provided.

(b) If at any time the Collateral Agent shall resign or be removed or otherwise become incapable of acting, or if at any time, a vacancy shall occur in the office of the Collateral Agent for any other cause, a successor trustee or trustees may be appointed by the Majority Holders, and the powers, duties, authority and title of the predecessor trustee or trustees terminated and canceled without procuring the resignation of such predecessor trustee or trustees, and without any other formality (except as may be required by applicable law) than appointment and designation of a successor trustee or trustees in writing, duly acknowledged, delivered to the predecessor trustee or trustees and Company, and filed for record in each public office, if any, in which this Agreement is required to be filed.

(c) The appointment and designation referred to in Section 6.7(b) shall, after any required filing, be full evidence of the right and authority to make the same and of all the facts therein recited, and this Agreement shall vest in such successor trustee or trustees, without any further act, deed or conveyance, all of the estate and title of its predecessor, and upon such filing for record the successor trustee or trustees shall become fully vested with all the estates, properties, rights, powers, trusts, duties, authority and title of its predecessor; but such predecessor shall, nevertheless, on the written request of the Majority Holders, Company or the successor trustee or trustees, execute and deliver an instrument transferring to such successor or successors all the estates, properties, rights, powers, trusts, duties, authority and title of such predecessor or predecessors hereunder and shall deliver all securities and

moneys held by it to such successor trustee or trustees. Should any deed, conveyance or other instrument in writing from any Trustor be required by any successor trustee or trustees for more fully and certainly vesting in such successor trustee or trustees the estates, properties, rights, powers, trusts, duties, authority and title vested or intended to be vested in the predecessor trustee or trustees, any and all such deeds, conveyances and other instruments in writing shall, on request of such successor trustee or trustees, be executed, acknowledged and delivered by such Trustor.

(d) Any required filing for record of the instrument appointing a successor trustee or trustees as hereinabove provided shall be at the expense of the Trustors. The resignation of any trustee or trustees and the instrument or instruments removing any trustee or trustees, together with all other instruments, deeds and conveyances provided for in this Section 6 shall, if permitted by law, be forthwith recorded, registered and filed by and at the expense of the Trustors, wherever this Agreement is recorded, registered and filed.

6.8 Status of Successors to the Collateral Agent.

Except as permitted by Section 6.7, every successor to the Collateral Agent appointed pursuant to Section 6.7 shall be a bank or trust in good standing and having power so to act, incorporated under the laws of the United States or any State thereof or the District of Columbia, and having its principal corporate trust office within the 48 contiguous States, and shall also have (together with its corporate affiliates) capital, surplus and undivided profits of not less than $100,000,000, if there be such an institution with such capital, surplus and undivided profits willing, qualified and able to accept the trust upon reasonable or customary terms.

6.9 Merger of the Collateral Agent.

Any corporation into which the Collateral Agent may be merged, or with which it may be consolidated, or any corporation resulting from any merger or consolidation to which the Collateral Agent shall be a party, or any corporation to which the Collateral Agent shall transfer all or substantially all of its corporate trust business (including the administration of this trust) shall be trustee under this Agreement without the execution or filing of any paper or any further act on the part of the parties hereto.

6.10 Co-Trustee, Separate Trustee.

(a) If at any time or times it shall be necessary or prudent in order to conform to any law of any jurisdiction in which any of the Collateral shall be located, or the Collateral Agent shall be advised by counsel, satisfactory to it, that it is so necessary or prudent in the interest of the Holders, or the Majority Holders shall in writing so request the Collateral Agent and the Trustors, or the Collateral Agent shall deem it desirable for its own protection in the performance of its duties hereunder, the Collateral Agent and the Trustors shall execute and deliver all instruments and agreements necessary or proper to constitute another bank or trust Company, or one or more persons approved by the Collateral Agent and the Trustors, either to act as co-trustee or co-trustees of all or any of the Collateral, jointly with the Collateral Agent originally named herein or any successor or successors, or to act as separate trustee or trustees of any such property. In the event the Trustors shall not have joined in the execution of such instruments and agreements within 30 days after the receipt of a written request from the Collateral Agent so to do, or in case an Actionable Default shall have occurred and be continuing, the Collateral Agent may act under the foregoing provisions of this Section 6.10 without the concurrence of the Trustors, and the Trustors hereby appoint the Collateral Agent as its agent and attorney to act for it under the foregoing provisions of this Section 6.10 in either of such contingencies.

(b) Every separate trustee and every co-trustee, other than any trustee that may be appointed as successor to the Collateral Agent, shall, to the extent permitted by law, be appointed and act and be such, subject to the following provisions and conditions, namely:

(i) all rights, powers, duties and obligations conferred upon the Collateral Agent in respect of the custody, control and management of moneys, papers or securities shall be exercised solely by the Collateral Agent, or its successors as trustee hereunder;

(ii) all rights, powers, duties and obligations conferred or imposed upon the Collateral Agent hereunder shall be conferred or imposed and exercised or performed by the Collateral Agent and such separate trustee or separate trustees or co-trustee or co-trustees, jointly, as shall be provided in the instrument appointing such separate trustee or separate trustees or co-trustee or co-trustees, except to the extent that under any law of any jurisdiction in which any particular act or acts are to be performed the Collateral Agent shall be incompetent or unqualified to perform such act or acts, in which event such rights, powers, duties and obligations shall be exercised and performed by such separate trustee or separate trustees or co-trustee or co-trustees;

(iii) no power given hereby to, or that it is provided hereby may be exercised by, any such co-trustee or co-trustees or separate trustee or separate trustees, shall be exercised hereunder by such co-trustee or co-trustees or separate trustee or separate trustees, except jointly with, or with the consent in writing of, the Collateral Agent, anything herein contained to the contrary notwithstanding;

(iv) no trustee hereunder shall be personally liable by reason of any act or omission of any other trustee hereunder; and

(v) the Trustors and the Collateral Agent, at any time by an instrument in writing, executed by them, may accept the resignation of or remove any such separate trustee or co-trustee, and in that case, by an instrument in writing executed by the Trustors and the Collateral Agent jointly, may appoint a successor to such separate trustee or co-trustee, as the case may be, anything herein contained to the contrary notwithstanding. In the event that the Trustors shall not have joined in the execution of any such instrument within ten days after the receipt of a written request from the Collateral Agent so to do, or in case an Actionable Default shall have occurred and be continuing, the Collateral Agent shall have the power to accept the resignation of or remove any such separate trustee or co-trustee and to appoint a successor without the concurrence of the Trustors, the Trustors hereby appointing the Collateral Agent its agent and attorney to act for it in such connection in either of such contingencies. In the event that the Collateral Agent shall have appointed a separate trustee or separate trustees or co-trustee or co-trustees as above provided, it may at any time, by an instrument in writing, accept the resignation of or remove any such separate trustee or co-trustee, the successor to any such separate trustee or co-trustee to be appointed by the Trustors and the Collateral Agent, or by the Collateral Agent alone, as provided in this Section 6.10.
