2. Section 1 of the Agreement is amended to read in its entirety as follows:

1. Additional Deposits.  The Parties acknowledge that (a) prior to the date hereof the amount on deposit in the Account held by Constellation under the Certificate Purchase Agreement was $3,000,000 (the “Original Deposit Amount”), of which Trust I had an interest in $20,250, Trust III had an interest in $144,585, Trust IV had an interest in $858,540, Trust V had an interest in $883,125, B Fund had an interest in $114,750, and IES had an interest in $978,750, (b) for good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, on the date hereof and in accordance with the requirements of the Amendment, Trust IV deposited $3,000,000 in the Account (the “Trust IV Deposit”) and Trust V deposited $3,120,800 into the Account (the “Trust V Deposit” and together with the Trust IV Deposit, the “Additional Deposits”), (c) the aggregate amount of the Original Deposit Amount plus the Additional Deposits is equal to the New Deposit Amount as of the date of this Agreement, and (d) notwithstanding the fact that the Trusts and IES provided the Original Deposit Amount and Trust IV and Trust V are providing the Additional Deposits, the Original Deposit Amount and the Additional Deposits are for the account of Indeck Maine, RPPP and RRIG under the Certificate Purchase Agreement prior to the Transaction Effective Date and for the account of Xxxxxxx, RPPP and RRIG under the Certificate Purchase Agreement as of and after the Transaction Effective Date.

2. Reallocation of Deposits at Closing.  Effective at and as of the Transaction Effective Date, the Parties agree that the New Deposit Amount shall be allocated among the Parties as set forth in this Section 2.

(a) Xxxxxxx, immediately upon its receipt of the Indeck Maine Deposit and without any further action required, shall transfer and assign its entire interest in the New Deposit Amount to each of IES, Trust IV and Trust V so that such interest is allocated among Trust IV, Trust V and IES proportionately to their other interests in the Account after giving effect to the reallocation described in Section 2(b).

(b) Each of the Trusts and IES will reallocate the New Deposit Amount among them such that the interests of each of the Trusts and IES as of the Transaction Effective Date is as set forth on Schedule 2(b). On the Transaction Effective Date, RRP will calculate any additional amount that a Trust or IES is required to pay or receive in order to effect the overall allocation of the New Deposit Amount among the Trusts and IES set forth on Schedule 2(b), which calculation shall be binding upon the Trusts and IES absent manifest error. To the extent that any Trust or IES is required to make such a payment, such Trust or IES will pay that amount to RRP, for the benefit of the Trusts not making those payments, on the Transaction Effective Date, and with respect to IES, such payment shall be made from the proceeds of the sale of its interest in Indeck Maine. To the extent that, as a result of that reallocation, a Trust is due an amount in order to effect the overall allocation of the New Deposit Amount set forth on Schedule 2(b), RRP will use the funds paid to it on the Transaction Effective Date pursuant to the preceding sentence to make that payment to each Trust that is due an amount from the Account.

(c) The percentage interests of the Trusts and IES in the Account (including any releases from the Account) are as set forth on Schedule 1 (prior to the Transaction Effective Date) and Schedule 2(b) (as of and after the Transaction Effective Date), regardless of where legal title to the New Deposit Amount may reside, and any amounts held in the Account are subject to the rights and security interests of Constellation in such interests.

4. Schedule 1 to the Agreement is amended in its entirety to read as Exhibit A to this Amendment.

5. Schedule 2(b) to the Agreement is amended in its entirety to read as Exhibit B to this Amendment.

6. In connection with the transactions contemplated by the PSA, as amended by the PSA Amendment, Xxxxxxx agrees, and the other Parties and RRP acknowledge, that on the Transaction Effective Date Xxxxxxx will acquire the “Renewable Energy Certificates” and “Accounts Receivable” described in Exhibit M to the PSA, as added to the PSA by the PSA Amendment, not in its individual capacity but as agent for Ridgewood Maine, L.L.C. (“RM”) and IES. Xxxxxxx will use commercially reasonable efforts to collect the amounts due on the Accounts Receivable. To the extent that Xxxxxxx receives payment on those Accounts Receivable or sells those Renewable Energy Certificates as agent for RM and IES, Xxxxxxx will pay the net amount received, after the payment of all commissions and other transaction expenses made to third parties, according to Section 7(d) of the Sellers Omnibus Agreement dated as of August 19, 2008 among RM, IES and, for certain limited purposes, RRP, as amended (which payment will be effected by Xxxxxxx paying that net amount to RM, as escrow agent for RM and IES, and RM, as such escrow agent, disbursing those amounts according to Section 7(d) of the Sellers Omnibus Agreement); provided, however, that except as set forth in this paragraph 6, Xxxxxxx shall have no obligation to sell or otherwise realize any value from any such Renewable Energy Certificates.

Upon execution hereof, each reference in the Agreement to “this Agreement,” “hereby,” “herein,” “hereof” or words of similar import referring to the Agreement shall mean and refer to the Agreement as amended by this Amendment.
