(c) In the event funds transfer instructions are given (other than in writing at the time of the execution of this Security Agreement), whether in writing, by facsimile or otherwise, the Trustee is authorized to seek confirmation of such instructions by telephone call-back to the person or persons designated on Schedule 3.01 hereto, and the Trustee may rely upon the confirmations of anyone purporting to be the person or persons so designated. The persons and telephone numbers for call-backs may be changed only in writing actually received and acknowledged by the Trustee. The parties to this Security Agreement acknowledge that such security procedure is commercially reasonable.

(d) It is understood that the Trustee and the beneficiary’s bank in any funds transfer may rely solely upon any account numbers or similar identifying number provided to identify (i) the beneficiary, (ii) the beneficiary’s bank, or (iii) an intermediary bank.

(e) The Depository hereby agrees and confirms that it has established the Trustee Accounts as set forth and defined in this Security Agreement.

The Depository agrees that each item of property (including a security, security entitlement, investment property, instrument or obligation, share, participation, interest or other property whatsoever) credited to any Trustee Account shall to the fullest extent permitted by law be treated as a Financial Asset.

(f) Until all Obligations have been satisfied in full, the Trustee shall have “control” (within the meaning of Section 8-106(d)(2) or Section 9-104(a) (as applicable) of the UCC) of the Trustee Accounts and the Issuer’s “security entitlements” (within the meaning of Section 8-102(a)(17) of the UCC) with respect to the Financial Assets credited to the Trustee Accounts. All Property delivered to the Depository pursuant to this Security Agreement will

-14-

be promptly credited to the applicable Trustee Account pursuant to this Security Agreement. The Issuer hereby irrevocably directs, and the Depository (in its capacity as securities intermediary) hereby agrees, that the Depository will comply with all written instructions and orders (including entitlement orders within the meaning of Section 8-102(a)(8) of the UCC) regarding each Trustee Account and any Financial Asset therein originated by the Trustee without the further consent of the Issuer or any other Person. In the case of a conflict between any instruction or order originated by the Trustee and any instruction or order originated by the Issuer or any other Person other than a court of competent jurisdiction, the instruction or order originated by the Trustee shall prevail. The Depository shall not change the name or account number of any Trustee Account without the prior written consent of the Trustee (such consent not to be unreasonably withheld or delayed) and at least ten (10) Business Days prior notice to the Issuer, and shall not change the entitlement holder with respect to the Financial Assets credited thereto.

(g) In the event any Trustee Account is determined not to qualify as a “securities account” (within the meaning of Section 8-501(a) of the UCC), such Trustee Account shall be deemed to be a “deposit account” (as defined in Section 9-102(a)(29) of the UCC), which the Issuer shall maintain with the Depository acting not as a securities intermediary but as a “bank” (within the meaning of Section 9-102(a)(8) of the UCC).

The Issuer agrees that if an Event of Default exists or a Default exists and the Required Senior Creditors believe that there could be a Material Adverse Effect on the value of the Collateral, the Trustee may act as attorney-in-fact for the Issuer in obtaining, adjusting, settling and canceling such insurance and receiving and endorsing any drafts. If the Issuer shall fail to provide and pay for any such insurance as set forth in Schedule 9.4 to the Note Purchase Agreement, the Trustee may (but shall not be required to), provide or pay for the same, at the expense of the Issuer, as set forth in Schedule 9.4 to the Note Purchase Agreement.

(b) In the event of any damage, destruction, condemnation, taking or taking for use (any such event referred to herein as an “Event of Loss”) with respect to any portion of the Project in excess of $75,000 (singly or in the aggregate), the Issuer shall notify, in writing, the Secured Parties of such Event of Loss, in accordance with Section 7.1(f) of the Note Purchase Agreement. The Issuer agrees that, upon the occurrence of an Event of Loss, it shall promptly pay any and all proceeds (including, without limitation, condemnation or insurance proceeds) received by it in respect of such Event of Loss, up to an amount equal to the then outstanding principal amount of the Note, plus accrued interest thereon, to the Trustee to be held by the Trustee (together with all income thereon) pursuant to this Security Agreement as part of the Collateral securing the Obligations. The Trustee shall deposit all such payments received from the Issuer or directly from any insurer or condemning authority in an account maintained with itself (the “Insurance and Condemnation Proceeds Account”), provided, however, that all proceeds of business interruption insurance shall be deposited by the Trustee into the Revenue Account, in accordance with Section 3.02(a). Except as otherwise provided in Section 4.06(f), the Issuer shall be obligated to repair, replace or reconstruct the Project subject to an Event of Loss to a condition substantially equivalent to its condition immediately prior to such Event of Loss or to a condition of at least equivalent value, regardless of whether the insurance proceeds covering such damage or destruction, or the amount of the award or compensation for damages recovered on account of such taking or condemnation, shall be sufficient to pay the cost thereof. The repair, replacement or reconstruction of the Project shall be completed within a period of six (6) months after the Event of Loss, which period shall be extended to nine (9) months so long as (i) there is no Default or Event of Default at the time of the Event of Loss and (ii) the Issuer demonstrates to the satisfaction of the Independent Engineer and the Administrative Agent that (A) the construction budget and the schedule for the repair, replacement or reconstruction of the Project are adequate and reasonable, (B) the insurance proceeds received by or due to the Issuer in relation to such Event of Loss (other than the proceeds of any business interruption insurance), together with

-32-

other amounts contributed to the Issuer or otherwise committed to the Issuer for such repair, replacement or reconstruction on terms that are acceptable to the Required Senior Creditors, will be sufficient to complete such repair, replacement or reconstruction, (C) the Issuer will be able to make all scheduled payments on the Notes during such repair, replacement or reconstruction without drawing on the Debt Service Reserve Letter of Credit or the amounts on deposit in the Debt Service Reserve Account, and (D) the Issuer is diligently pursuing such repair, replacement or reconstruction. Any extension of the deadline to complete the repair, replacement or reconstruction of the Project beyond nine (9) months shall be subject to the written consent of the Senior Creditors.

(c) For the purposes of this Section 4.06, the Project shall be deemed to be in a condition substantially equivalent to its condition or value immediately prior to an Event of Loss affecting it if the Project can be used effectively for substantially the same quantity and quality of generation and transmission of electric energy, capacity and related products for commercial sale for which it was used immediately prior to such Event of Loss, as certified in a report of the Independent Engineer as to the condition of the Project in form, scope and substance reasonably satisfactory to the Required Senior Creditors.

(d) (i) If, from time to time on or before the date that is six (6) months immediately succeeding the occurrence of an Event of Loss (or such longer period as may be authorized pursuant to Section 4.06(b)), the Issuer shall deliver to the Trustee and the Senior Creditors a certificate in substantially the form of Exhibit E hereto (an “Insurance Withdrawal Certificate”), signed by a Senior Financial Officer of the Issuer, certifying as to:

(A) the amount requested to be withdrawn from the Insurance and Condemnation Proceeds Account for the Project for the next month as reimbursement for expenses previously incurred, presently due and payable, or to become due and payable within one (1) month in connection with the restoration of the Project to a condition substantially equivalent to its condition or value immediately prior to such Event of Loss (the “Restoration Costs”);

(B) the attached copies of bills or other written evidence of individual costs describing the items purchased and/or the services rendered and all other pertinent schedules, statements, invoices, change orders or other information; and

(C) a reconciliation of all Restoration Costs disbursed through the date of such Insurance Withdrawal Certificate to the projected total costs of restoring the Project to a condition substantially equivalent to its condition or value immediately prior to such Event of Loss (the “Projected Total Restoration Costs”), demonstrating that, after giving effect to the proposed withdrawal, the amounts remaining on deposit in the Insurance and Condemnation Proceeds Account with respect to such Event of Loss are sufficient to pay the Projected Total Restoration Costs of such Project (taking into account any additional amounts not otherwise subject to the lien of this Security Agreement deposited by the Issuer with the Trustee for the purpose of effecting such restoration);

-33-

and further certifying in such Insurance Withdrawal Certificate that (1) all the amounts of Restoration Costs set forth in the certificate have been paid, are presently due and payable or shall be due and payable within one (1) month, (2) none of such amounts has been the subject of any prior payment request submitted to the Trustee, and (3) the entire amount of the withdrawal requested in clause (A), above, shall be used to pay, or to reimburse the Issuer for payment of, the Restoration Costs set forth in the Insurance Withdrawal Certificate, then, upon written approval thereof by the Required Senior Creditors and the Independent Engineer (which written approvals shall be given, or refused to be given, to the Issuers, and a copy of such written approvals shall be given to the Trustee, within ten (10) days of the receipt of such Insurance Withdrawal Certificate), the Trustee shall, within three (3) Business Days of its receipt of a copy of the written approvals thereof by the Required Senior Creditors and the Independent Engineer, transfer funds on deposit in the Insurance and Condemnation Proceeds Account as directed by the Issuer in the Insurance Withdrawal Certificate (such Insurance Withdrawal Certificate shall include a wire transfer instruction and all amounts disbursed hereunder shall be wired by the Trustee directly to the entity due such amounts).

The Issuer hereby agrees that all funds received by it pursuant to this Section 4.06(d)(i) shall be applied exclusively to the payment of, or reimbursement for, Restoration Costs which have been properly identified in an Insurance Withdrawal Certificate. No more than one Insurance Withdrawal Certificate shall be delivered to the Trustee in any single calendar month.

(ii) If on the date that is six (6) months immediately succeeding the occurrence of an Event of Loss (or such longer period as may be authorized pursuant to Section 4.06(b)) the Project has not been restored to a condition substantially equivalent to its condition or value immediately prior to such Event of Loss, then the Issuer shall give written notice thereof to the Secured Parties and the Independent Engineer, and the Issuer shall either (A) deposit with the Trustee, out of funds of the Issuer not held in the Accounts within thirty (30) days of the date of such notice, an amount determined by the Independent Engineer to be sufficient, when combined with the amounts on deposit in the Insurance and Condemnation Proceeds Account attributable to such Event of Loss, to complete the restoration of the Project to a condition substantially equivalent to its condition or value immediately prior to such Event of Loss, or (B) prepay, in accordance with the provisions of Section 8.2(a) of the Note Purchase Agreement, a principal amount of the Note equal to the sum of (x) the amount of insurance proceeds held by the Trustee in the Insurance and Condemnation Proceeds Account with respect to such Event of Loss, and (y) all amounts previously disbursed from the Insurance and Condemnation Proceeds Account with respect to such Event of Loss as the principal amount thereof, together with interest accrued to the date of prepayment on the principal amount being prepaid, but without a prepayment premium. In the event that the Issuer elects, pursuant to clause (A) above, to restore the Project to a condition substantially equivalent to its condition or value immediately prior to such Event of Loss and, on the date that is six months immediately succeeding the date of the notice provided under this Section 4.06(d)(ii) (or such longer period as may be authorized pursuant to Section 4.06(b)), the Project has not been restored to a condition substantially equivalent to its condition or value immediately prior to such Event of Loss, then the Issuer shall prepay, in accordance with the provisions of Section 8.2(a) of the Note Purchase Agreement, a principal amount of the Note equal to the

-34-

sum of (x) the amount of the insurance proceeds held by the Trustee in the Insurance and Condemnation Proceeds Account with respect to such Event of Loss and (y) the amount of such insurance proceeds previously disbursed from the Insurance and Condemnation Proceeds Account with respect to such Event of Loss, but without a prepayment premium.

(e) The Issuer, immediately upon obtaining Knowledge of the institution of any proceedings for the condemnation or other taking of the Collateral or any portion thereof in excess of $75,000 (singly or in the aggregate), or the use thereof, shall, in accordance with Section 7.1(f) of the Note Purchase Agreement, notify, in writing, the Secured Parties of the pendency of such proceedings. The Trustee or the Senior Creditors, may, but shall not be obligated to, participate in such proceedings (including, without limitation, the making of any compromise or settlement in connection with such proceedings), if such participation is deemed desirable by the Senior Creditors, and the Issuer agrees to deliver to the Trustee or the Senior Creditors, all instruments requested by them from time to time to permit such participation. The Trustee is hereby irrevocably appointed as the Issuer’s attorney-in-fact, coupled with an interest, with exclusive power to make, during the continuance of any Event of Default, any compromise or settlement in connection with such proceedings at the written direction of the Required Senior Creditors.

(f) In the event all or substantially all of the Project is damaged, destroyed, condemned or otherwise taken, the Issuer shall prepay, in accordance with the provisions of Section 8.2(a) of the Note Purchase Agreement, the entire outstanding principal amount of the Note together with interest accrued to the date of prepayment on the principal amount being prepaid and all other amounts due under the Loan Documents, but without a prepayment premium. In the event any portion of the Project is subject to an Event of Loss, but less than substantially all of the Project is affected by such Event of Loss, the Issuer shall not be obligated to repair, replace or reconstruct any such portion if, the Issuer is diligent pursuing the decision as to whether to repair, replace or reconstruct such portion and on or prior to the date six months immediately succeeding such Event of Loss, the Issuer in its good faith judgment determines that it would be uneconomic to repair, replace or reconstruct such portion. If the Issuer makes such determination and so certifies to the Trustee on or prior to the date six months immediately succeeding such Event of Loss, the Issuer shall, upon the earliest of the expiration of such six-month period or the time proceeds, if any, of insurance, condemnation or taking are received with respect to such Event of Loss, promptly make the prepayment described above in this Section 4.06(f).

(g) The Issuer at its own expense, upon request by the Trustee or the Required Senior Creditors, shall make, execute and deliver any and all instruments reasonably requested for the purposes of confirming the assignment of the aforesaid insurance proceeds, awards and compensation to the Trustee, free and clear of any Liens of any kind or nature whatsoever.

Obligations, (b) shall not be deemed, under any circumstances, to be account balances or assets of the Issuer maintained with the Trustee and (c) are held by the Trustee solely in its capacity as trustee pursuant to this Security Agreement and for no other purpose. Accordingly, and notwithstanding anything to the contrary contained in any bank credit agreement or any other agreement, the Trustee hereby waives and disclaims any right it might have to set-off any amounts in such Trustee Account against any indebtedness now or hereafter owing by the Issuer to the Trustee in its individual capacity and not as trustee hereunder or any bank for which the Trustee acts as agent.

(f) Should any deed, conveyance or instrument in writing from the Issuer be required by any successor Trustee for more fully and certainly vesting in and confirming to such successor Trustee the estates, rights, powers and duties granted to the Trustee hereunder, then upon request any and all such deeds, conveyances and instruments in writing shall be made, executed, acknowledged and delivered, and shall be caused to be recorded and/or filed, by the Issuer.

-58-

(g) Any successor Trustee appointed pursuant to any of the provisions hereof shall execute, acknowledge and deliver to the Issuer, the Senior Creditors, the Administrative Agent and the Master Servicer an instrument accepting such appointment; and thereupon such successor Trustee, without any further act, deed or conveyance, shall become vested with all the estates, assets, rights, powers and trusts of its predecessor Trustee hereunder and under the other Security Documents and the Consents with like effect as if originally named herein; but nevertheless, upon the written request of the Issuer or of the successor Trustee, such predecessor Trustee shall immediately execute and deliver an instrument (presented to it in execution form) transferring to such successor Trustee, upon the trusts herein expressed, all the estates, assets, rights, powers and trusts of such predecessor Trustee, and shall duly assign, transfer and deliver to the successor Trustee all of the assets and moneys so held or as may be received from time to time by such predecessor Trustee, including all amounts in the Trustee Accounts, to be held by the successor Trustee as Trustee hereunder.

In the event that the Issuer shall not have joined in the execution of such instrument within fifteen (15) days after the receipt of a written request from the Trustee to do so, or in case an Event of Default shall have occurred and be continuing, the Trustee may act under the foregoing provisions of this Section 6.05 without the concurrence of the Issuer; and the Issuer hereby irrevocably makes, constitutes and appoints the Trustee as the agent and attorney-in-fact for the same to act for it under the foregoing provisions of this Section 6.05 in either of such contingencies.

(b) Every additional Trustee, co-Trustee and separate Trustee hereunder shall, to the extent permitted by law, be appointed and act (and the Trustee shall act) in accordance with the following provisions and conditions:

(i) all rights, powers, privileges, duties and obligations conferred or imposed upon the Trustee in respect of the receipt, custody, investment and payment of monies shall be exercised solely by the Trustee;

(ii) all other rights, powers, privileges, duties and obligations conferred or imposed upon the Trustee shall be conferred or imposed upon and exercised or performed by the Trustee, except to the extent that under any law of any jurisdiction in which any particular act or acts are to be performed the Trustee shall be incompetent or unqualified to perform such act or acts, in which event such rights, powers, privileges, duties and obligations (including the holding of title to the Collateral in any such jurisdiction) shall be exercised and performed by such additional Trustee or Trustees, co-Trustee or co-Trustees or separate Trustee or Trustees;

(iii) no such additional Trustee, co-Trustee or separate Trustee shall exercise any power created hereby or provided for hereunder except jointly with, or with the consent of, the Trustee; and

In the event that the Issuer shall not have joined in the execution of such instrument, the Trustee may act on behalf of the same to the same extent as provided above.

-60-

or for any reason such office shall become vacant, all the estates, interests, properties, rights, powers, privileges, trusts, duties and obligations of such additional Trustee, co-Trustee or separate Trustee, as the case may be, in respect of the Collateral, so far as permitted by law, shall vest in and be exercised by the Trustee without the appointment of a successor to such additional Trustee, co-Trustee or separate Trustee unless and until a successor shall be appointed in the manner provided above.

(d) Any written request, approval or consent by the Trustee to any additional Trustee, co-Trustee or separate Trustee shall be sufficient warrant to such additional Trustee, co-Trustee or separate Trustee, as the case may be, to take such action as may be so requested, approved or consented to.
