Introduction

As described below, Ridgewood Maine L.L.C. and Indeck Energy Services, Inc. (the “Sellers”) have entered into a Purchase and Sale Agreement to sell 100 percent of the membership interests of Indeck Maine Energy, LLC to Covanta Energy Corporation for cash, pursuant to the terms and subject to the conditions of such Purchase and Sale Agreement. Ridgewood Maine L.L.C. is owned 50% by Ridgewood Electric Power Trust IV and 50% by Ridgewood Electric Power Trust V. The allocation among the Sellers of the proceeds of the transaction provided for in the Purchase and Sale Agreement is set forth in the Sellers Omnibus Agreement, which is summarized below.

In addition, Trust V, Trust IV and certain of their affiliates, have made certain changes in their relationship with a power marketer that purchases Renewable Portfolio Standards Attributes produced by Indeck Maine Energy, LLC and by methane gas powered electric generating plants owned by Trust IV and the affiliated entities, pursuant to an amendment to that agreement and pursuant to the terms of the Backup Certificate Agreement, the Certificate Sale Support Agreement and the Agency Agreement, each of which is summarized below.

Purchase and Sale Agreement

On August 22, 2008, Ridgewood Maine L.L.C., a Delaware limited liability company (“Ridgewood Maine”), and Indeck Energy Services, Inc., an Illinois corporation (“Indeck Energy” and together with Ridgewood Maine, the “Sellers”), entered into a Purchase and Sale Agreement (the “Purchase and Sale Agreement”), dated as of August 19, 2008 (the “Effective Date”), with Covanta Energy Corporation, a Delaware corporation (the “Buyer”) and for certain limited purposes, Indeck Maine Energy, LLC, an Illinois limited liability company (“Indeck Maine”), pursuant to which the Sellers will sell to the Buyer all of the Sellers’ interest in Indeck Maine.

Ridgewood Maine is owned 50% by Ridgewood Electric Power Trust IV (“Trust IV”) and 50% by Ridgewood Electric Power Trust V (“Trust V”). Each of Trust IV and Trust V (together, the “Trusts”) is a Delaware trust. Ridgewood Renewable Power LLC, a New Jersey limited liability company (the “Managing Shareholder”), serves as the managing shareholder for each of the Trusts. The Managing Shareholder is controlled by Robert E. Swanson, who is the manager, chairman, and, together with his family trusts, owns all of the membership interests of the Managing Shareholder. Ridgewood Maine is managed by Ridgewood Penobscot Management Corp. (“Ridgewood Penobscot”), a corporation for which Mr. Swanson is the sole director. Ridgewood Maine holds a preferred interest in Indeck Maine, and Indeck Energy, which is not affiliated with the Trusts, the Managing Shareholder or Ridgewood Penobscot, holds the subordinate interest in Indeck Maine. In addition to these interests, as of the Effective Date, Ridgewood Maine and Indeck Energy also hold notes issued by Indeck Maine that are to be converted into senior preferred membership units in Indeck Maine as of the date of Closing (as defined below) pursuant to the terms and conditions of the Sellers Omnibus Agreement described below (the preferred interest, subordinate interest and the senior preferred membership units being collectively referred to as the “Interests”). Ridgewood Maine and Indeck Energy together own 100% of Indeck Maine.

Pursuant to the Purchase and Sale Agreement, the Sellers are to sell to the Buyer (the “Sale”) all of the Interests of Indeck Maine owned by the Sellers for an aggregate amount (the “Purchase Price”) equal to (i) $82,000,000 (the “Initial Amount”) plus (ii) a working capital payment equal to $8,956,817 (which represents the net working capital of Indeck Maine at May 31, 2008 and includes cash of $4,354,976) plus (iii) interest on the Initial Amount and the working capital payment accruing at

2

4.26% per annum from May 31, 2008 to and including the closing date, minus (iv) the Retention Amount (described below), minus (v) a vacation accrual amount equal to $47,137. The proceeds of the Sale will be allocated among the Sellers as set forth in the Sellers Omnibus Agreement.

Concurrent with the Sale and as a condition to the execution and delivery of the Purchase and Sale Agreement, approximately 30 days prior to the scheduled date of Closing (as defined below), the Buyer intends to offer employment to all employees of Ridgewood Power Management, LLC (“Ridgewood Power”) working at the sites of the projects owned by Indeck Maine, subject to and in accordance with the terms set forth in an Employee Transfer Agreement, including, without limitation, the payment of retention bonuses and severance payments, which payments will not be more than $1,114,597.20 (the “Retention Amount”). Ridgewood Power, which is an affiliate of the Managing Shareholder and the Trusts, provides managerial and operating services to Indeck Maine.

The Purchase and Sale Agreement provides that the Sale will occur five business days after the date on which all of the closing conditions are either satisfied or waived by the party for whose benefit the particular closing condition exists, unless otherwise agreed to by the parties to the Purchase and Sale Agreement (the “Closing”). The Managing Shareholder anticipates that Closing will occur in the fourth quarter of 2008. No assurance can be given that the Sale will occur at all, or that if it does occur, that it will occur during the time anticipated by the Managing Shareholder.

The Closing is subject to various closing conditions, including approval of the Sale by shareholders of each of the Trusts, the receipt of the requisite notifications under the Hart-Scott-Rodino Antitrust Act and approval of the Federal Energy Regulatory Commission.

The Purchase and Sale Agreement includes representations and warranties from each of the Sellers and the Buyer as to their respective organization, authority to execute and deliver the Purchase and Sale Agreement and certain related agreements and to perform their respective obligations under the Purchase and Sale Agreement and certain related agreements. Additionally, the Sellers represent and warrant to the Buyer regarding the business and assets of Indeck Maine to be conveyed to the Buyer. Except for certain representations and warranties of the Sellers regarding ownership of the Interests and related matters, the representations and warranties terminate at Closing, or in the absence of Closing, the earlier termination of the Purchase and Sale Agreement.

At Closing, all accounts and contracts between Indeck Maine and the Sellers or their affiliates that are not specifically listed in the Purchase and Sale Agreement will be terminated with no further liability or force or effect.

Buyer will indemnify each Seller, its affiliates, successors and assigns, and all of their respective shareholders against losses that result from (i) any third party claim against any Seller based on the Buyer’s ownership or operation of Indeck Maine on or after the date of Closing, (ii) all environmental liabilities arising on or after the date of Closing and (iii) a breach of the Buyer’s obligations under the Employee Transfer Agreement described below. The indemnity for losses described in (i) and (ii) of this paragraph is limited to a total of 20% of the Purchase Price.

The Sellers and the Buyer may terminate the Purchase and Sale Agreement by mutual written consent at any time prior to Closing, even if the shareholders of the Trusts have approved the transactions contemplated under the Purchase and Sale Agreement. The Purchase and Sale Agreement may be terminated by the Sellers or the Buyer if, among other reasons, (i) the other party has breached any representation, warranty or covenant contained in the Purchase and Sale Agreement in any material respect, so long as the non-breaching party has notified the other party of the breach and the breach has continued without cure for a period of 60 days after the notice of breach or (ii) the Closing does not occur

3

before October 31, 2008, unless the failure to close results primarily from the non-breaching party itself breaching any representation, warranty or covenant or failing to fulfill any of its obligations contained in the Purchase and Sale Agreement.

The Sellers may terminate the Purchase and Sale Agreement if (i) the Sellers are unable to obtain approval of the Sale by shareholders of the Trusts or (ii) prior to receipt of approval of the Sale by shareholders of the Trusts, the Sellers have received a superior proposal for the Interests, as defined in, and subject to the terms and conditions set forth in the Purchase and Sale Agreement, and the Sellers agree to pay to the Buyer an amount equal to 5% of the Purchase Price as a termination fee.

Pursuant to an amendment to an agreement with a power marketer which purchases Renewable Portfolio Standards Attributes (“RPS Attributes”) from Indeck Maine and methane gas powered electric generating plants owned by Ridgewood Electric Power Trust I (“Trust I”), Ridgewood Electric Power Trust III (“Trust III”), Trust IV and Ridgewood Power B Fund/Providence Expansion (“B Fund”) located in Johnston, Rhode Island, Trust IV deposited $3,000,000 and Trust V deposited $3,120,000 (together with funds already on deposit, the “Deposit”) into an account that serves as security to a power marketer for the performance by Indeck Maine, Ridgewood Providence Power Partners, L.P. (“RPPP”) and Ridgewood Rhode Island Generation, LLC (“RRIG”) of their respective obligations to sell RPS Attributes derived from electric power generated at their plants. As of the date hereof, the Deposit totals approximately $9,121,000, plus accrued interest. Upon the Closing, the Deposit is re-allocated, and as a result, $1,410,875 and $1,662,355 will be returned to Trust IV and Trust V, respectively.

Subject to and upon Closing, Linwood 0708 LLC, a newly formed Delaware limited liability company managed by the Managing Shareholder and owned by Trust IV (“Linwood”), will assume and discharge Indeck Maine’s rights, obligations and liabilities under the agreement with the power marketer to sell RPS Attributes derived from electric power generated at their plants arising on and after the Closing. The other parties and the Trusts have consented, to the extent required, to this assignment and assumption and have agreed to accept Linwood’s performance of Indeck Maine’s obligations under such agreement in the place of Indeck Maine arising on and after Closing. Indeck Maine has agreed with Linwood, RPPP and RRIG, subject to certain limitations, to deliver the RPS Attributes needed for Linwood to perform its obligations under this agreement in the Backup Certificate Agreement (described below).

Backup Certificate Agreement

Indeck Maine, RPPP, RRIG, Linwood, Rhode Island LFG Genco, LLC (“RILG”, an affiliated Delaware limited liability company), and for limited purposes, the Buyer, have entered into a Backup Certificate Agreement, dated as of August 19, 2008, (the “Backup Agreement”). The operative provisions of the Backup Agreement shall become effective upon the Closing. Subject to such provisions of the Backup Agreement, Indeck Maine has agreed to sell to RPPP, RRIG, Linwood and RILG (the “Backup Purchasers”) a portion of its RPS Attributes, to be used in satisfaction of RPPP’s, RRIG’s and Linwood’s obligations under the agreement with the power marketer to provide the power marketer with the RPS Attributes required to satisfy its option to purchase additional RPS Attributes for 2008 (and for 2009, if the power marketer so elects). If the power marketer fails to exercise its option for 2009, the related provisions in the Backup Agreement will have no further force or effect.

In the event that Indeck Maine delivers fewer RPS Attributes than it is required to deliver under the Backup Agreement, Indeck Maine will pay damages to the Backup Purchasers, as calculated in the Backup Agreement. Pursuant to the Backup Agreement, the Buyer will deliver to the Backup Purchasers a guaranty of the obligations of Indeck Maine to pay those damages under the Backup Agreement, with an amount guaranteed not to exceed 80 percent of the Deposit and not to exceed $7,300,000.

4

Pursuant to an Agency Agreement dated as of August 19, 2008 among RPPP, RRIG, Linwood, Ridgewood Power and Indeck Maine (the “Agency Agreement”), Indeck Maine will deliver its RPS Attributes under the Backup Agreement directly to the power marketer in satisfaction of RPPP’s, RRIG’s and Linwood’s obligations under the agreement with the power marketer and will be paid directly by the power marketer for those RPS Attributes.

Under the Purchase and Sale Agreement and the Backup Agreement, RPPP, RRIG and Linwood must obtain Buyer’s or Indeck Maine’s consent to amend the agreement with the power marketer if that amendment would impact Indeck Maine’s rights and obligations under the Backup Agreement or the Agency Agreement. The Backup Purchasers must deposit $6,000,000 in escrow (the “Backup Deposit”) if they enter into an amendment that materially reduces their contractual incentives or remedies of the power marketer under such agreement, which Backup Deposit will serve as collateral for their obligations to Indeck Maine under the Backup Agreement. The Backup Purchasers, Indeck Maine and Capital One N.A., as escrow agent, entered into an escrow agreement, dated as of August 19, 2008, to arrange for Capital One to hold the Backup Deposit in escrow if the Backup Deposit were to be required.

Sellers Omnibus Agreement

In connection with the Sale, the Sellers, and for limited purposes, the Managing Shareholder, have entered into a Sellers Omnibus Agreement, dated as of August 19, 2008. Subject to the provisions of the Sellers Omnibus Agreement and effective three days prior to the scheduled Closing date, each of the Sellers will contribute to Indeck Maine certain promissory notes previously issued to such Sellers for loans made by such Sellers to Indeck Maine. In exchange for such contributions, such Sellers will be issued units of a new class of membership interests in Indeck Maine (the “Senior Preferred Membership Units”). Indeck Maine will cancel the promissory notes upon the issuance of the Senior Preferred Membership Units.

Pursuant to the Sellers Omnibus Agreement, each of Ridgewood Maine and Indeck Energy have authorized the Managing Shareholder to act on its behalf in connection with the preparation of the Purchase and Sale Agreement or of an alternative agreement reflecting a superior proposal to the Sale.

In the event the Sale closes, or alternatively, in the event of the closing of a superior proposal to the Sale, the proceeds of the Sale or the superior proposal will be allocated between the Sellers as follows: (i) first, to the payment of transaction costs attributable to the sale of the Interests, allocated 55% from the proceeds otherwise to be received by Ridgewood Maine and 45% from the proceeds otherwise to be received by Indeck Energy; (ii) second, to Ridgewood Maine and Indeck Energy according to their pro rata ownership of the Senior Preferred Membership Units; and (iii) third, due to their differing priority status, all remaining proceeds will be paid 55% to Ridgewood Maine and 45% to Indeck Energy.

Certificate Sale Support Agreement

The Certificate Sale Support Agreement, dated as of July 31, 2008, by and among Linwood, RRIG, RPPP, RILG, Trust I, Trust III, Trust IV, Trust V, B Fund, Indeck Energy and Ridgewood Power provides for the allocation of title to the Deposit, the allocation of the Backup Deposit as described above, and the allocation of any liability among the parties to the Certificate Sale Support Agreement and the Backup Agreement in the event of a default thereunder whereby damages are payable.

Prior to the Closing, title to the Deposit is to be allocated as set forth in Schedule 1 to the Certificate Sale Support Agreement. After the Closing, the amount in the Deposit is to be reallocated as set forth in Schedule 2(b) to the Certificate Sale Support Agreement.

5

In addition, the Certificate Sale Support Agreement calls for each of its parties to be responsible for payments under the Backup Agreement or losses under the agreement with the power marketer that are caused by a breach of those agreements. Linwood is responsible for payments due to Indeck Maine for RPS Attributes purchased under the Backup Agreement (to the extent Indeck Maine is not paid directly by the power marketer) and for losses incurred by the other parties under the agreement with the power marketer as a result of Indeck Maine’s failure to deliver RPS Attributes under the Backup Agreement. To the extent that the Backup Deposit is required to be funded, the Certificate Sale Support Agreement provides for RPPP to deposit 27.23% of that amount and for RRIG to deposit 72.77% of that amount. Finally, the Certificate Sale Support Agreement requires Trust V to indemnify Trust IV for 50% of any losses incurred by Trust IV as a result of its ownership of Linwood.

The foregoing description of the Sale and the agreements referred to does not purport to be complete and is qualified in its entirety by reference to the full text of the Purchase and Sale Agreement, the Guaranty of Covanta Energy Corporation, the Agency Agreement, the Backup Certificate Agreement, the Sellers Omnibus Agreement and the Certificate Sale Support Agreement, each of which is filed as an exhibit to this report and is incorporated by reference herein.

If Buyer fails to propose an alternative response to such Emergency Situation as described above within 24 hours of receipt of Sellers’ notice and proposal or if Sellers conclude in good faith that (i) Buyer’s alternative proposal for such Emergency Situation does not conform to Good Engineering Practices or (ii) such proposal cannot be implemented within a time period, at a cost and with a likelihood of success better than or comparable to Sellers’ original proposal, then Sellers shall implement Sellers’ proposed response for such Emergency Situation without further action required.

The parties acknowledge and agree that (i) nothing contained in this Agreement shall give Buyer, directly or indirectly, the right to control or direct the Company’s operations during the Interim Period and prior to the Closing Date, (ii) prior to the Closing Date, the Sellers and the Company shall exercise, consistent with the terms and conditions of this Agreement, complete control and supervision over the Company’s operations, and (iii) notwithstanding anything to the contrary set forth in this Agreement, no consent of Buyer will be required with respect to any matter set forth in the Agreement to the extent the requirement of such consent would violate any applicable laws.

6.4 Full Access.

(a) During the Interim Period, each Seller shall cause the Company, and the Company agrees to (i) permit Buyer and Representatives of Buyer during normal business hours to have access upon reasonable notice, in a manner so as not to interfere with the normal business operations of the Company or RPMC, to the Sites, Assets, all premises, properties, management, personnel, books, records (including Tax records) and documents associated with the Projects and to permit Buyer to make such reasonable inspections thereof as Buyer may reasonably request, (ii) provide Buyer with copies of the Daily Production Report (similar in form and content to those currently produced by the Company, as provided in Exhibit I attached hereto) for each of the Projects, which shall be provided on the Tuesday following the end of the week for which it is reporting, and (iii) furnish Buyer with a copy of each material report, schedule or other document filed or received by Sellers or the Company with respect to the Projects with a Governmental Authority. During the Interim Period, Sellers

21

shall keep Buyer reasonably and promptly informed on any significant operating matters with respect to the Company and the Projects. Notwithstanding the foregoing, and without limiting the generality of the confidentiality provisions set forth in Section 9, Sellers shall not be obligated to cause the Company, nor shall the Company be obligated, to: (A) provide any information that the Company or the Company’s counsel believes constitutes or could be deemed to constitute a waiver of the attorney-client privilege, or (B) supply Buyer with any information or records that the Company or its Affiliates are under a legal obligation not to supply, in the case of (A) and (B) above, however, the parties agree that they shall use their Commercially Reasonable Efforts to cause such information or records to be provided to Buyer in a manner that does not cause such violation or waiver of privilege.

(b) During the Interim Period, at the sole cost and expense of Buyer, each Seller shall cause the Company, and the Company agrees, to permit designated Representatives of Buyer (the “Buyer’s Observers”) to observe all operations of the Projects and such observation shall be permitted on a cooperative basis in the presence of personnel of the Company during normal business hours and upon reasonable advance notice; provided that Buyer’s Observers shall not interfere with the operation of either Project.

6.5 [Intentionally Left Blank]

6.6 Interim Period Notice; Schedule Update.  

(a) Sellers shall notify Buyer promptly if any information comes to their attention prior to the Closing that is likely to (i) excuse Sellers from the performance of their obligations under this Agreement or (ii) cause any condition to the Closing set forth in Sections 8.1 or 8.2 not to be satisfied.

(b) From time to time prior to the Closing Date, each Seller shall supplement or amend and deliver updates to the Schedules (each a “Schedule Update”) that are necessary to complete or correct any information in such Schedules or in any representation or warranty of such Seller that has been rendered inaccurate since the Effective Date. Any Schedule Update delivered pursuant to this Section 6.6 shall not be deemed to cure any breach of a representation, warranty, covenant or agreement or to satisfy any condition hereunder.

6.7 Further Assurances.  At any time and from time to time after the Closing, at the request of Buyer and at Buyer’s expense, Sellers shall execute and deliver such instruments of sale, transfer, conveyance, assignment and confirmation and take such action as Sellers and Buyer may reasonably agree is necessary to transfer, convey and assign to Buyer, and to confirm Buyer’s title to or interest in the Interests.

6.8 Insurance.  Each Seller agrees that after the Closing it will use and will cause its Affiliates to use Commercially Reasonable Efforts to cooperate with all reasonable requests of Buyer or the Company to facilitate or permit such parties to make claims on or after the Closing under any insurance policies of the Company in place, and related to claims relating to the period, prior to the Closing, provided that (i) Buyer or the Company shall pay any applicable deductibles related to such policies, and (ii) neither Sellers nor their respective Affiliates are required to take any actions that could expose any of them to claims or cause them to incur unreimbursed costs.

6.9 Access after Closing.  For a period of one year after the Closing Date, Buyer shall have reasonable access to all of the records, books and documents of Sellers related to the Company and Projects to the extent that such access may reasonably be required in connection with matters relating to or affected by the operations of the Company or Projects prior to the Closing Date (including, without limitation, liabilities with respect to Taxes); provided that Sellers shall have the right, at their sole cost and expense to retain copies of such records, books and documents, subject to their obligation to keep such information confidential in accordance with Section 9. Such access shall be afforded upon receipt of reasonable advance notice and during normal business hours. Buyer shall be solely responsible for any costs or expenses incurred by it or Sellers pursuant to this Section 6.9. If Sellers shall desire to dispose of any records, books or documents that may relate to operations of the Company or Projects before the Closing prior to the expiration of such one-year period, Sellers shall, prior to such disposition, give Buyer a reasonable opportunity, at the Buyer’s expense, to segregate and remove such records, books or documents as Buyer may select. Buyer acknowledges that one or both of Sellers and/or certain of their Affiliates may liquidate their assets and dissolve, and notwithstanding the foregoing, nothing set forth in this Section 6.9 shall be deemed to restrict or limit in any way any right of

22

Sellers and any Affiliate of Sellers to liquidate their assets and dissolve prior to the conclusion of such one-year period.

6.10 Exclusivity.  

(a) Until the Closing Date or earlier termination of this Agreement pursuant to Section 12, neither Sellers nor the Company, except in connection with the operation of the Projects in the ordinary course of business (including in satisfaction of any contractual obligations), shall, nor shall any of them permit its respective Affiliates, officers, directors, employees, representatives and agents to, directly or indirectly, encourage, solicit, or initiate discussions or negotiations with, or provide any information to, any Person or group of Persons (other than Buyer or any of its Affiliates) in furtherance of, or any proposal for the acquisition (whether by purchase of the Equity Interests or Assets) of the Company or the Projects, any merger, consolidation, business combination, reorganization, recapitalization, or similar transaction involving the Company or the Projects or any other transaction or series of transactions that would result in any person or business entity other than Buyer or its Affiliates acquiring control of the Company, the Assets and/or the Projects (an “Alternate Transaction”). Without limiting the obligations under the preceding sentence, in the event that (1) Sellers receive a proposal for an Alternate Transaction, then Sellers shall (i) promptly (but in no event in less than twenty four hours) notify Buyer in writing of such Alternate Transaction, (ii) include in such notification the terms of any such proposal or offer that it may receive with respect thereto (and provide Buyer with a copy thereof in writing), including the identity of the soliciting party, and (iii) keep Buyer informed with respect to the status of the foregoing, and (2) RRP as the managing shareholder of Ridgewood Electric Power Trust IV and Ridgewood Electric Power Trust V determines that the Alternate Transaction of which Buyer was previously notified constitutes or is reasonably likely to lead to a Superior Proposal, then Sellers shall promptly (but in no event in less than twenty four hours) notify Buyer in writing of such determination. Neither Sellers nor the Company shall, after the date of this Agreement, enter into any confidentiality agreement that would prohibit it from providing such information to Buyer.

(b) Sellers shall use Commercially Reasonable Efforts to require any Third Party (or its agents, employees or advisors), in possession of Proprietary Information about Sellers, the Company or the Projects that was furnished by or on behalf of Sellers or the Company, to return or destroy all such information in accordance with the applicable confidentiality agreements to which such Third Parties are a party.

(c) Notwithstanding the foregoing provisions of paragraph 6.10(a), Sellers and RRP may, subject to Sellers’ compliance with Section 6.10(a) above and prior to obtaining the shareholder approval of Ridgewood Electric Power Trust IV and Ridgewood Electric Power Trust V, engage in negotiations or discussions regarding an Alternate Transaction with any third party that has made an unsolicited bona fide written proposal for an Alternate Transaction, which RRP as the managing shareholder of Ridgewood Electric Power Trust IV and Ridgewood Electric Power Trust V, has determined in good faith (after consultation with its outside legal counsel and financial advisors) constitutes or is reasonably likely to lead to a Superior Proposal. For purposes of clarification, the issuance by RM of the Confidential Information Memorandum dated February 28, 2008 and any discussions and negotiations with recipients thereof and bidders in response to such memorandum through June 2, 2008 do not constitute a solicitation hereunder by Sellers.

(d) In the event Sellers provide notice to Buyer regarding a proposed Superior Proposal pursuant to Section 6.10(a) above, Buyer shall have a right exercisable by written notice to Sellers within a period of ten (10) days following Sellers’ notice to match all of the terms of any such proposal (a “Matching Proposal”). In the event that Buyer makes a binding Matching Proposal to Sellers, Sellers shall negotiate in good faith with Buyer to amend this Agreement to reflect such Matching Proposal. If the Agreement is not amended and executed and delivered by Sellers and Buyer within five (5) Business Days of the date on which Buyer gave notice of the Matching Proposal, then Sellers may reject such Matching Proposal and proceed with the negotiation and consummation of the Superior Proposal.

6.11 Affiliate Transactions.  Sellers and the Company shall cause (i) all accounts, whether payables or receivables, between the Company, on the one hand, and Sellers or any of its Affiliates, on the other hand, to be paid or released in full prior to the Closing; and (ii) except as set forth on Schedule 6.11, all other

23

Contracts between the Company, on the one hand, and Sellers or any of its Affiliates, on the other hand, to be terminated with no further liability or other force or effect after the Closing.

6.12 Bank Statements.  No later then five (5) Business Days prior to the Closing Date, the Sellers and the Company shall deliver daily to Buyer, for the period from the Purchase Price Date and through such date, copies of all bank statements pertinent to the Company’s bank accounts as listed on Schedule 6.12 (the “Bank Statements”). Sellers and Company shall further continue to deliver such Bank Statements to Buyer for each subsequent Business Day until the Closing. In addition to and notwithstanding the agreements of the Parties set forth in Section 6.4 herein, the Company shall give Buyer and its authorized representatives reasonable access to the books and records of the Company and assistance to Buyer, as Buyer may reasonably request during normal business hours, in conducting its review and verification of the cash transactions set forth in such Bank Statements.

6.13 Disclosure of Violations or Defaults.  Sellers and the Company shall promptly inform Buyer of (a) any violations of current Laws applicable to the Company and each Project or terms of current Permits held by the Company each as described in Section 4.5 of this Agreement of which Sellers have Knowledge from the date hereof up to, and including, the Closing Date, and (b) any condition or event of which Sellers have Knowledge from the date hereof up to, and including, the Closing Date that, with notice or lapse of time or both, would constitute a material default, or permit termination, modification or acceleration, by any party under any Project Contract.

6.14 Replacement Insurance Policies.  Sellers or the Company shall promptly provide copies of any replacement insurance policies that the Company obtains following the date hereof as contemplated in Section 4.7.

6.15 Interim Period Notice.  Each Seller shall promptly notify Buyer if any information comes to its attention prior to the Closing that it believes is likely to (i) excuse such Seller from the performance of its obligations under this Agreement or any Ancillary Agreements to which it is a party, or (ii) cause any condition to the Closing set forth in Sections 8.1 or 8.2 not to be satisfied.

6.16 Assignment, Assumption, Release and Amendment Agreement.  With respect to the Interim Period, notwithstanding the provisions of Section 6.3 above, the Company shall not, and Sellers shall cause their Affiliates not to, amend or modify any term, condition or covenant of the Certificate Purchase Agreement unless (a) Sellers give or cause their Affiliates to give Buyer prior written notice of any such proposed amendment or modification, including a copy of the proposed documentation to effect such amendment or modification, and (b) Sellers comply, or cause their Affiliates to comply, with the following procedures, upon Buyer’s reasonable opportunity to review such notice (together with all necessary and appropriate documentation), which opportunity to review will in no event be longer than ten (10) Business Days after receipt of such notice and all such necessary and appropriate documentation that may be reasonably requested by Buyer:

(i) in the event that Buyer reasonably determines that such proposed amendment or modification of the Certificate Purchase Agreement could reasonably be expected to have an adverse impact on the Company’s rights or obligations under any material term, condition or covenant of the Backup Agreement or the Agency Agreement prior to or on and after the Closing, the Company shall not, and Sellers shall not permit their Affiliates to amend or modify any such material term, condition or covenant of the Certificate Purchase Agreement having such adverse impact on the Company without obtaining Buyer’s prior written consent to any such amendment or modification, such consent of Buyer not to be unreasonably withheld, conditioned or delayed; and

(ii) in the event that Buyer reasonably determines that clause (i) above does not apply to such proposed amendment or modification of the Certificate Purchase Agreement and that such proposed amendment or modification could reasonably be expected to materially reduce the contractual incentives or remedies for performance of any terms, conditions or covenants of Ridgewood Providence Power Partners, L.P., Ridgewood Rhode Island Generation, LLC or Linwood under the Certificate Purchase Agreement prior to or on and after the Closing (including any reduction in or modification to collateral, terms of guaranties or other security arrangements other than an immaterial reduction in or modification

24

to collateral, terms of guaranties or other security arrangements), the Company shall not, and Sellers shall not permit their Affiliates to amend or modify any such term, condition or covenant of the Certificate Purchase Agreement without providing to Buyer or, with respect to the period on and after Closing, to the Company, on the later of (Y) the Closing Date or (Z) prior to execution of the first such amendment or modification, a one-time cash deposit in the amount of $6,000,000, to be held as collateral security pursuant to the Backup Agreement to secure the performance of Ridgewood Providence Power Partners, L.P., Ridgewood Rhode Island Generation, LLC, Linwood and Rhode Island LFG Genco, LLC under the Backup Agreement and the Agency Agreement.

25

7.3 Interim Period Notice.  Buyer shall promptly notify Sellers if any information comes to its attention prior to the Closing that it believes is likely to (i) excuse Buyer from the performance of its obligations under this Agreement or any Ancillary Agreements to which it is a party, or (ii) cause any condition to the Closing set forth in Sections 8.1 or 8.2 not to be satisfied.

9.1 Confidentiality.  

(a) Each Receiving Party and each Representative thereof shall treat and hold as confidential all of the Proprietary Information, and refrain from using any of the Proprietary Information except in connection with this Agreement and the transactions contemplated hereby. In the event that the Receiving Party or any Representative thereof is requested or required including, without limitation, (i) pursuant to any rule or regulation of any stock exchange or other self-regulatory organization upon which any of the Receiving Party’s securities are listed or (ii) by oral question or request for information or documents in any legal proceeding, interrogatory, subpoena, civil investigative demand, or similar process (other than the processes associated with the approvals and consents of, and filings with, any Governmental Authority required to consummate the transactions contemplated in this Agreement) to disclose any Proprietary Information, the Receiving Party shall notify the Disclosing Party promptly of the request or requirement so that the Disclosing Party may seek an appropriate protective order or a waiver of compliance with the provisions of this Section 9. If, in the absence of a protective order or the receipt of a waiver hereunder, the Receiving Party or any Representative thereof is, on the advice of counsel, compelled to disclose any Proprietary Information pursuant to any such request or requirement, then the Receiving Party or such Representative may disclose the Proprietary Information so requested or required to be disclosed; provided that the Receiving Party shall use Commercially Reasonable Efforts to obtain, at the request of the Disclosing Party, an order or other assurance that confidential treatment shall be accorded to such portion of the Proprietary Information required to be disclosed as the Disclosing Party shall designate. If this Agreement is terminated pursuant to Section 12.1, then each Receiving Party shall deliver promptly to the Disclosing Party or destroy, at the request and option of the Disclosing Party, all tangible embodiments (and all copies) of the Proprietary Information that are in his or its possession.

(b) The obligations of the Parties contained in this Section 9 shall be in full force and effect for three (3) years from the date hereof and shall survive the termination of this Agreement, the discharge of all other obligations owed by the Parties to each other and any transfer of the Interests or the Assets. Nothing in this Section 9 shall in any way alter Buyer’s obligations under the Confidentiality Agreement.

(c) Notwithstanding the foregoing, the Receiving Party may provide Proprietary Information to the FERC, the SEC, the United States Department of Justice, the United States Federal Trade Commission or any other Governmental Authority with jurisdiction, as necessary, to obtain any consents, waivers or approvals as may be required for the Receiving Party to undertake the transactions contemplated herein. The Parties consent to the disclosure of such Proprietary Information to the extent that the Receiving Party reasonably determines that such disclosure is reasonably necessary in order to obtain such consents, waivers or approvals, provided, however, that the Receiving Party shall provide the Disclosing Party with a draft language of such disclosures at least forty-eight (48) hours prior to any disclosure of such Proprietary Information and the Disclosing Party shall use Commercially Reasonable Efforts to negotiate with the Receiving Party on a mutually acceptable language.

(d) The Parties acknowledge that the information required to be provided to the shareholders of Ridgewood Electric Power Trust IV and Ridgewood Electric Power Trust V in order to obtain the approvals described in Section 8.2(g) may include Proprietary Information of one of more of the Parties and that such

29

information shall become publicly available by virtue of its dissemination to such shareholders and its filing with the SEC.

10.  Taxes

10.1 Liability for Taxes.  

(a) Buyer shall be responsible for and pay all Taxes arising or resulting from the Buyer’s ownership of the Company after the Closing Date.

(b) Buyer shall pay to Sellers the amounts of any refund, abatement or credit of Taxes received by the Buyer for Taxes that are attributable to the Sellers’ ownership of the Company or any Interest on or prior to the Closing.

(c) Sellers shall pay to Buyer the amounts of any refund, abatement or credit of Taxes received by Sellers for Taxes that are attributable to the Buyer’s ownership of the Company or any Interest after the Closing.

(d) Sellers shall cause the Company to prepare and timely file and to remit any Taxes that are due in respect of the following Tax Returns on or before the Purchase Price Date with respect to the Company or in respect to its business, assets or operations: (i) all Tax Returns for any taxable period ending on or before the Closing Date; and (ii) all other Tax Returns required to be filed (taking into account extensions) prior to the Closing Date. Buyer shall prepare and timely file or shall cause to be prepared and timely filed by the Company all Tax Returns that are required to be filed by or with respect to the Company or in respect to its business, assets or operations for taxable years or periods beginning and ending after the Closing Date. Buyer shall remit or cause to be remitted by the Company any Taxes due in respect of such Tax Returns. With respect to any Tax Returns of the Company that relate to periods that begin before and end after the Closing Date, (i) Buyer shall prepare or cause to be prepared such Tax Returns in a manner consistent with past practices, if any, except as otherwise required by applicable Law, and (ii) not less than fifteen days prior to the due date for such Tax Returns (including proper extensions), Buyer shall present such Tax Returns to Sellers for their comments (provided that in the event that it is not practical for any such Tax Returns to be prepared fifteen days prior to the due date, including proper extensions, Buyer shall present such Tax Return to Sellers for their comments as soon as such Tax Return has been prepared), Buyer shall consider in good faith any comment received from Sellers no later than five days prior to the due date for such Tax Return. Sellers shall be responsible for (and shall pay to Buyer within five days of a written request of such amount) that portion of such Taxes that are allocable to the portion of such period that ends on the Purchase Price Date and Buyer shall be responsible for the payment of such Taxes relating to the portion of such period beginning immediately after the Purchase Price Date. Notwithstanding any other provision of this Section 10.1 to the contrary, Sellers’ obligation to remit or otherwise incur any liability with respect to any Taxes shall not apply to the extent that such Taxes are reflected as an accrued liability or in a reserve on the Company Balance Sheet and such failure to comply with such obligation is not a violation of applicable Laws.

(e) Buyer and Sellers agree to cooperate and share, before, at and after the Closing, all required information on a timely basis in order to timely file all Tax Returns, reports, returns, schedules and any other documents required to be filed with respect to Taxes and all claims for refunds of Taxes and for the preparation of any audit, and for the prosecution or defense of any claim or proceeding relating to any proposed adjustment. Buyer and Sellers agree to retain or cause to be retained all Tax Returns, and books and records pertinent to the Company and the Interests until the applicable period for assessment under applicable Law (giving effect to any and all extensions or waivers) has expired, and to abide by or cause the abidance with all record retention agreements entered into with any Governmental Authority. After the Closing, Buyer and Sellers shall give each other reasonable notice prior to transferring, discarding or destroying any such Tax

30

Returns, and books and records relating to Tax matters, and Buyer and Sellers shall allow each other upon request to take possession of such Tax Returns, and books and records at the requesting Party’s expense. Buyer and Sellers shall cooperate with each other in the conduct of any audit or other proceedings involving the Company or the Interests for any Tax purpose. Sellers shall have the sole right to represent the Company’s interests in any audit or examination by any Governmental Authority (“Tax Audit”) relating to taxable periods ending on or before the Closing and to employ counsel of its choice at its expense. In the case of a period that begins before and ends after Closing, Sellers shall be entitled to participate at its expense in any Tax Audit relating in any part to Taxes attributable to the portion of such period deemed to end on or before the Closing Date, but Buyer shall control the Tax Audit. None of Buyer, any of its Affiliates or the Company may settle or otherwise dispose of any Tax Audit for which Sellers may have a liability under this Agreement, or that may result in an increase in Sellers’ liability under this Agreement, without the prior written consent of Sellers, which consent may not be unreasonably withheld. At Sellers’ request, Buyer shall cause the Company to make or join with Sellers in making elections with respect to its Tax Returns for periods ending on or before the Closing, provided that the making of such election does not have a Material Adverse Effect on the Company for any post-Closing Tax period.

(f) Any payment by Buyer or Sellers under this Section 10.1 shall be deemed an adjustment to the Purchase Price.

(g) All excise, sales, use, transfer (including real property transfer or gains), stamp, documentary, filing, recordation and other similar taxes, together with any interest, additions or penalties with respect thereto and any interest in respect of such additions or penalties, but expressly excluding Taxes measured by net income (the “Transfer Taxes”), resulting from the transfer of the Interests pursuant to this Agreement shall be borne by Buyer. Each Party will cooperate, at such Party’s expense, to take such commercially reasonable actions as will minimize or reduce the amount of Transfer Taxes.

(h) Buyer and Sellers agree to report all items of income, gain, or loss consistent with the principles set forth in Situation 2 of Revenue Ruling 99-6 whereby: (i) the Company shall be treated as terminating pursuant to Code Section 708(b)(1)(A); (ii) Sellers shall report the gain or loss on the sale of the Interests in accordance with Code Section 741; and (iii) Buyer shall treat the acquisition as if the Company made a liquidating distribution of its Assets to Sellers and, immediately following such liquidating distribution, Buyer acquired by purchase all of the Company’s Assets. The Parties agree that the Purchase Price and any other relevant items shall be allocated among the Assets in accordance with Section 1060 of the Code and the Treasury regulations thereunder. Within 90 days after the Closing Date, Buyer shall prepare and deliver to Sellers an allocation schedule allocating the Purchase Price and any such other relevant items among the Assets (the “Allocation Schedule”). The Allocation Schedule shall be final and binding on the parties unless, within 30 days after delivery thereof to the Sellers, the Sellers deliver a written notice to Buyer of its objections to the Allocation Schedule, in which case Buyer and Sellers shall attempt in good faith to resolve such dispute between them. If Buyer and Sellers are unable to resolve such dispute within thirty days thereafter, then Buyer and Sellers shall submit all such disputed items for resolution to an independent accountant mutually selected by Buyer and Sellers whose decision shall be final and binding upon all Parties. The fees of the independent accountant shall be shared equally by Buyer and Sellers. Buyer and Sellers shall (i) be bound by the Allocation Schedule for purposes of determining any Taxes, (ii) prepare and file their Tax Returns on a basis consistent with the Allocation Schedule, and (iii) take no position inconsistent with the Allocation Schedule on any Tax Return or in any proceeding before any taxing authority, provided, however, that nothing contained herein shall prevent Buyer and Sellers from settling any proposed deficiency or adjustment by any Governmental Authority based upon or arising out of the Allocation Schedule, and neither Buyer nor Sellers shall be required to litigate before any court, any proposed deficiency or adjustment by any Governmental Authority challenging the Allocation Schedule. Notwithstanding anything to the contrary in this Agreement, the parties agree that the draft Allocation Schedule and the final Allocation Schedule shall provide that: (i) an amount of the Purchase Price that is allocated to the unrealized receivables of the Company shall not exceed the face value of such

31

unrealized receivables as of the Closing Date, and (ii) an amount of the Purchase Price that is allocated to the inventory of the Company shall not exceed the book value of such inventory as of the Closing Date.

(i) All tax credits accruing under 26 U.S.C. § 45 on or prior to the Closing Date shall be allocated to and for the benefit of Sellers, all such tax credits accruing after the Closing Date shall be allocated to and for the benefit of Buyer.

11.   Risk of Loss; Indemnification; Remedies.

11.1 Survival of Representations and Warranties; Survival of Covenants and Agreements.  The representations and warranties of Sellers set forth in Section 3 and Section 4 and the representations and warranties of Buyer set forth in Section 5 shall terminate at the Closing or the earlier termination of this Agreement pursuant to Section 12.1, except that the representations and warranties set forth in Section 4.2 (Equity Interests) shall survive indefinitely. Subject to the survival provisions set forth in this Section 11.1 and the covenants of the Parties contained in this Agreement which by their terms survive the Closing, the representations, warranties and covenants contained herein shall terminate at the Closing or the termination of this Agreement pursuant to Section 12.1.

11.2 Risk of Loss.  Except as otherwise provided in this Section 11.2, during the Interim Period all risk of loss or damage to the property included in the Assets shall, as between Buyer and Sellers, be borne by Sellers. If during the Interim Period any Assets are damaged by fire or other casualty (each such event, an “Event of Loss”), or are taken by a Governmental Authority by exercise of the power of eminent domain (each, a “Taking”), then the following provisions of this Section 11.2 shall apply:

(a) The Sellers shall promptly notify Buyer within five (5) Business Days following the occurrence of any Event of Loss or Taking (or the commencement of any action by any Government Authority in the pursuit of any Taking) of which such Seller becomes aware.

(b) The occurrence of (i) any one or more Events of Loss, as a result of which the aggregate costs to restore, repair or replace the affected Project(s) are reasonably estimated to be an amount less than or equal to twenty percent (20%) of the value of the affected Project(s), and/or (ii) any one or more Takings, as a result of which (w) the aggregate condemnation proceeds equal an amount less than or equal to twenty percent (20%) of the value of the affected Project(s) and (x) (A) less than twenty percent (20%) of the total land area of any one Project is affected and (B) ingress and egress to and from the affected Project(s) is not materially adversely affected, shall have no effect on the transactions contemplated hereby provided that, Sellers shall cause the Company to restore, repair or replace the affected Project prior to the Closing, and in no event later than ninety (90) days following such Event of Loss or Taking.

(c) Upon the occurrence of (i) any one or more Events of Loss, as a result of which the aggregate costs to restore, repair or replace, the Project(s) are reasonably estimated to be an amount in excess of twenty percent (20%) of the value of the affected Project(s), or (ii) any one or more Takings, as a result of which (y) the aggregate condemnation proceeds equal an amount in excess of twenty percent (20%) of the value of the affected Project(s) or (z) (A) more than twenty percent (20%) of the total land area of any one Project is affected or (B) ingress and egress to and from the affected Project(s) is materially adversely affected (a “Major Loss”), Sellers shall have, in the case of a Major Loss relating to one or more Events of Loss, the option, exercised by notice to Buyer, to cause the Company to restore, repair or replace the damaged Assets prior to Closing. If Sellers elect to cause the Company to restore, repair or replace the Assets relating to a Major Loss, which election shall be made by notice to Buyer prior to the Closing Date and as soon as practicable following the occurrence of the Major Loss, Buyer shall have the option of (x) making the completion of the repair, replacement or restoration of the damaged Assets a condition to the Closing and the Closing Date shall be postponed at its election for the amount of time reasonably necessary to complete the restoration, repair or replacement of such damaged Assets, such time period to be agreed upon by Buyer and Sellers, or (y) allowing the Closing to occur prior to the completion of the repair, replacement or restoration of such damaged Assets; provided that Sellers shall have agreed to cause the completion of such repair, replacement or restoration, together with a credit support for Seller’s obligations reasonably acceptable to Buyer, which covenant shall survive the Closing.

32

If Sellers elect not to cause the restoration, repair or replacement of the Assets affected by a Major Loss, or such Major Loss is the result of one or more Takings, the provisions of Section 11.2(d) shall apply.

(d) In the event that Sellers elect not to cause the restoration, repair or replacement of a Major Loss, or in the event that Sellers, having elected to cause repair, replacement or restoration of the Major Loss, fail to cause its completion within the period of time agreed upon by the Parties pursuant to Section 11.2(c), or in the event that a Major Loss is the result of one or more Takings, then the Parties shall, within thirty (30) days following Sellers’ election not to cause the restoration, repair or replacement, failure to complete, or the occurrence of such Takings, as the case may be, attempt to negotiate in good faith an equitable adjustment in the Purchase Price to reflect the impact of the Major Loss, as mitigated by any repair, replacement or restoration work actually completed by Sellers on the Assets being sold to Buyer and proceed to Closing. To assist Buyer in its evaluation of any and all Events of Loss, Sellers shall provide Buyer such information as Buyer may reasonably request in connection therewith.

(e) In the event that the Parties fail to reach agreement on an equitable adjustment of the Purchase Price within the thirty (30) days provided in Section 11.2(d), then Buyer shall have the right to elect, exercisable by notice to Sellers within fifteen (15) days immediately following the expiration of the thirty (30) day period, to either (i) proceed with the consummation of the transaction at Closing, with a reduction in the Purchase Price consistent with Sellers’ last offer of equitable adjustment communicated to Buyer, in which event Sellers shall assign over or deliver to Buyer at Closing all condemnation proceeds or insurance proceeds that Sellers receive, or to which Sellers become entitled by virtue of the Event of Loss or Taking, less any costs and expenses reasonably incurred by Sellers in connection with such Event of Loss or Taking or in obtaining such condemnation proceeds or insurance proceeds and less the reduction in the Purchase Price made pursuant to this clause (i), or (ii) terminate this Agreement pursuant to Section 12.1(e).

(f) Notwithstanding the foregoing, the Parties acknowledge that any equitable adjustment of the Purchase Price provided in Section 11.2(d) or 11.2(e) may require the approval of the shareholders of Ridgewood Electric Power Trust IV and Ridgewood Electric Power Trust V. In the event such approval is required and the Sellers are unable to obtain that approval using Commercially Reasonable Efforts, Sellers may terminate this Agreement pursuant to Section 12.1(c).

(g) In the event that Sellers, prior to Closing and as a result of any Event of Loss, expended Sellers’ funds (i.e., not working capital or other funds of the Company) for the repair or replacement of items that were covered by insurance carried by the Company, then following the Closing, it is understood that Sellers shall be entitled to receive reimbursement for the full amount of such funds as named loss payees under the insurance carried by the Company. As loss payees, Sellers shall have the right to submit, adjust and settle any claim submitted to the Company’s insurance carrier. Buyer and Sellers shall cooperate with one another in good faith with respect to any such insurance claims submitted by any of them to the same insurance carrier and shall reasonably cooperate to avoid any action by either Sellers or Buyer that may have a material adverse effect on an insurance claim of Sellers or Buyer with respect hereto.

11.3 Effect of Closing.  Upon the Closing, any condition to the obligations of either Party hereunder that has not been satisfied, or any representation, warranty or covenant that has been breached or left unsatisfied by either Party shall be deemed waived by the Parties and each Party shall be deemed to fully release and forever discharge the other Party on account of any and all claims, demands or charges, known or unknown, with respect to the same, except that such waiver and release shall not apply with respect to Section 4.2 (Equity Interests), which shall survive the Closing pursuant to Section 11.1 hereof. Nothing in this Section 11.3 shall be deemed to affect any provision herein that expressly survives the Closing or pertains to matters that shall occur after the Closing.

11.4 Indemnity by Buyer.  Buyer shall indemnify, defend and hold harmless each Seller, its Affiliates, its and their successors and permitted assigns, and all of their respective shareholders, trustees, directors, managers, members, officers, employees, agents and representatives (collectively, “Sellers Indemnified Parties”) against and in respect of all Liabilities, obligations, judgments, Liens (except for Permitted Encumbrances), injunctions, charges, orders, decrees, rulings, damages, assessments, Taxes, losses, fines,

33

penalties, damages, expenses, fees, costs, and amounts paid in settlement (including reasonable consultants’, attorneys’ and expert witness fees and disbursements in connection with investigating, defending or settling any action or threatened action), arising out of any claim, complaint, demand, cause of action, audit, investigation, hearing, action, suit or other proceeding asserted or initiated or otherwise existing in respect of any matter (collectively, the “Losses”) that result from:

(a) any Third Party Claim against any Seller based on or relating to Buyer’s ownership or operation of the Company, including without limitation Buyer’s ownership, operation or use of the Projects, on or after the Closing Date;

(b) all Environmental Liabilities, arising on or after the Closing Date; and

(c) a breach of Buyer’s obligations under the Employee Transfer Agreement.

11.5 [Intentionally Left Blank].  

11.6 Limitations on Liability.  

(a) None of Sellers Indemnified Parties shall be entitled to recover from Buyer any indemnity under Section 11.4, (i) for any amount in excess of the actual compensatory damages, court costs and reasonable attorneys fees, suffered by such Sellers Indemnified Party and (ii) unless the aggregate amount of all Losses actually suffered by the Sellers Indemnified Parties exceeds $250,000, at which time the Sellers Indemnified Parties shall be entitled to indemnification for the entire amount of such Losses. Sellers on behalf of each of such Sellers Indemnified Parties waives any right to recover incidental, indirect, special, exemplary, punitive or consequential damages, including lost revenues or profits, even if such damages are foreseeable or the damaged Sellers Indemnified Party has advised Buyer of the possibility of such damages and regardless of whether any such damages are deemed to result from the failure or inadequacy of any exclusive or other remedy. In no event shall Buyer ever be required to indemnify Sellers or any Sellers Indemnified Parties for Losses pursuant to Section 11.4 in any amount exceeding, in the aggregate, twenty (20%) of the Purchase Price.

(b) None of the Sellers Indemnified Parties shall be entitled to any indemnity under Section 11.4 for a specific incident or event until and unless the amount of Losses actually suffered by the Sellers Indemnified Party exceeds $25,000 with respect to such individual incident or event, or a series of related incidents or events, and thereafter the entire amount of such Losses shall be eligible for indemnification, subject to the other limitations set forth herein. No Losses in an amount equal to or less than $25,000 for an individual incident or event, or a series of related incidents or events, shall be included in calculating the minimum aggregate amount contemplated in Section 11.6(a).

(c) The limitations set forth in this Section 11.6 shall not apply (1) in cases of fraud, or (2) any failure of Buyer to make payments as set forth in Section 2.4 or Section 2.5 of the Employee Transfer Agreement.

(d) No Sellers Indemnified Party entitled to indemnification hereunder or otherwise to damages in connection with or with respect to the transactions contemplated in this Agreement shall settle, compromise or take any other action with respect to any claim, demand, assertion of liability or legal proceeding that could materially prejudice or otherwise materially adversely affect the ability of Buyer to defend or otherwise settle or compromise with respect to such claim, demand, assertion of liability or legal proceeding without the prior written consent of Buyer, which consent shall not be unreasonably withheld, conditioned or delayed.

(e) Each Sellers Indemnified Party entitled to indemnification hereunder or otherwise to reimbursement for Losses in connection with the transactions contemplated in this Agreement shall use Commercially Reasonable Efforts to mitigate all Losses upon becoming aware of any event or circumstance that could reasonably be expected to give rise to any Losses that are indemnifiable or recoverable hereunder or in connection herewith.

(f) No Party shall have recourse whatsoever against any of the shareholders, trustees, directors, managers, members, officers, employees or representatives of the other Parties (including for such purposes, the shareholders, trustees, directors, managers, members, officers, employees, agents or representatives of any

34

Affiliate of a Party). Without limiting the generality of the foregoing, Buyer, on behalf of itself and its Affiliates, and Sellers, on behalf of themselves, their Affiliates and Sellers Indemnified Parties, each hereby fully and irrevocably waives any right, claim or entitlement whatsoever against such trustees, directors, managers, members, officers, employees or representatives relating to any and all Losses suffered or incurred by any of them arising from, based upon, related to, or associated with this Agreement.

11.7 Waiver and Release by Seller.  Effective as of the Closing, each Seller, on behalf of itself, its members and shareholders and each of its and their past, present and future Affiliates, beneficiaries, successors and assigns (“Related Persons”), hereby releases and forever discharges the Company and each of their respective past, present and future Affiliates, subsidiaries, members, successors and assigns, and their respective managers, officers, directors and employees (each individually, a “Releasee” and collectively, “Releasees”), from any and all claims, demands, proceedings, causes of action, court orders, obligations, contracts, agreements (express or implied), debts and liabilities under or relating to the Interests, the Projects, the Company or any of their predecessors in interest, whether known or unknown, suspected or unsuspected, both at law and in equity, which Sellers or any of its Related Persons now has, has ever had or hereafter has against the respective Releasees as a result of any act, circumstance, occurrence, transaction, event or omission on or prior to the Closing Date. Notwithstanding the foregoing, Sellers do not release, and this Section 11.7 shall not be deemed to affect, any claim of Sellers or their Related Persons or any obligation of Buyer pursuant to this Agreement or the Ancillary Agreements to which it is a party.

11.8 Remedies.  Except as provided in Section 13.17, from and after the Closing, any remedies set forth in the Ancillary Agreements to which Buyer is a party, shall constitute Buyer’s, its Affiliates’ and Buyer Indemnified Parties’ sole and exclusive remedies for any and all claims, damages, complaints, demands, causes of action, investigations, hearings, actions, suits or other proceedings relating to this Agreement and to the Ancillary Agreements (if applicable), and is in lieu of any and all other rights and remedies that Buyer, its affiliates and Buyer Indemnified Parties may have under this Agreement and the Ancillary Agreements to which Buyer is a party, or otherwise for monetary relief with respect to any breach or failure to perform. Each Party waives any provision of law to the extent that it would limit or restrict the agreements contained in this Section 11 or in the Ancillary Agreements to which such Party is a party. Nothing herein shall prevent either Party from terminating this Agreement in accordance with Section 12.

11.9 Matters Involving Third Parties.  

(a) If any Third Party shall notify a Sellers Indemnified Party with respect to any matter (a “Third Party Claim”) that may give rise to a claim for indemnification against any Buyer under this Section 11, then such Sellers Indemnified Party shall promptly notify Buyer thereof in writing; provided that no delay on the part of such Sellers Indemnified Party in notifying Buyer shall relieve Buyer from any obligation hereunder unless (and then solely to the extent) Buyer is prejudiced thereby.

(b) Buyer shall have the right to defend the Sellers Indemnified Party against the Third Party Claim with counsel of its choice reasonably satisfactory to the Sellers Indemnified Party so long as (i) within thirty (30) days after receiving such notice, Buyer shall give written notice to the Sellers Indemnified Party stating whether it disputes the claim for indemnification and whether it shall defend against any Third Party Claim or liability at its own cost and expense, (ii) the Third Party Claim involves only money damages and does not seek an injunction or other equitable relief and settlement of, or an adverse judgment with respect to, the Third Party Claim is not, in the good faith judgment of the Sellers Indemnified Party, likely to establish a precedential custom or practice adverse to the continuing business interests of the Sellers Indemnified Party, and (iii) Buyer conducts the defense of the Third Party Claim actively and diligently; provided that if the claim is one that cannot by its nature be defended solely by Buyer, the Sellers Indemnified Party shall make available all information and assistance reasonably available and necessary for the defense of the Third Party Claim as Buyer may reasonably request and shall cooperate with Buyer, in such defense.

(c) So long as Buyer is conducting the defense of the Third Party Claim in accordance with Section 11.9(b), (i) the Sellers Indemnified Party may retain separate co-counsel at its sole cost and expense and participate in the defense of the Third Party Claim, (ii) the Sellers Indemnified Party shall not consent to the entry of any judgment or enter into any settlement with respect to the Third Party Claim without the prior

35

written consent of Buyer (which consent shall not unreasonably be withheld, conditioned or delayed), and (iii) Buyer shall not consent to the entry of any judgment or enter into any settlement with respect to the Third Party Claim unless written agreement is obtained releasing the Sellers Indemnified Party from all liability thereunder.

(d) In the event any of the conditions in Section 11.9(b) is or becomes unsatisfied, however, (i) the Sellers Indemnified Party may defend against, and consent to the entry of any judgment or enter into any settlement with respect to, the Third Party Claim in any manner it may deem appropriate (and the Sellers Indemnified Party need not consult with, or obtain any consent from, Buyer in connection therewith), (ii) Buyer shall reimburse the Sellers Indemnified Party promptly and periodically for the reasonable costs of defending against the Third Party Claim (including reasonable attorneys’ fees and expenses), and (iii) Buyer shall remain responsible for any Losses the Sellers Indemnified Party may suffer resulting from, arising out of, relating to, in the nature of, or caused by the Third Party Claim to the fullest extent provided in this Section 11.

11.10 Net of Insurance.  Any calculation of a Loss under this Section 11 shall, in each case, give full effect to any and all insurance proceeds received or payable to the Sellers Indemnified Party in respect of the Loss. Any such Loss shall not take into account, and shall not be increased to reflect, the Tax consequences to the Sellers Indemnified Party of the receipt of (or the right to receive) the indemnification payments.

12.   Termination.

12.1 Termination of Agreement.  The Parties may terminate this Agreement as provided below:

(a) the Parties may terminate this Agreement by mutual written consent at any time prior to the Closing;

(b) Either Buyer or Sellers may terminate this Agreement by giving written notice to the other Party at any time prior to the Closing if any of the following has occurred: (i) the other Party has breached any representation, warranty or covenant contained in this Agreement in any material respect, the non-breaching Party has notified the other Party of the breach, and the breach has continued without cure for a period of sixty (60) days after the notice of breach; (ii) the Closing shall not have occurred on or before October 31, 2008 (the “Termination Date”) by reason of the failure of any condition precedent under Section 8.1 or Section 8.2, unless the failure results primarily from the non-breaching Party itself breaching any representation, warranty, or covenant or failing to fulfill any of its obligation contained in this Agreement; (iii) one or more courts of competent jurisdiction shall have issued an order, judgment or decree permanently restraining, enjoining or otherwise prohibiting the Closing, which order, judgment or decree shall not have been terminated, lifted, vacated or otherwise rendered irrelevant within ninety (90) days of the issuance thereof, provided, however, that the Party seeking to terminate this Agreement pursuant to this Section 12.1(b) shall have used Commercially Reasonable Efforts to prevent the entry of and to remove such order, judgment or decree; (iv) any Law shall have been enacted by any Governmental Authority that, directly or indirectly, prohibits the consummation of the transactions contemplated hereby; or (v) the other Party becomes bankrupt or insolvent; (vi) either Sellers or Buyer have received from any Person from whom any waiver, consent, permit, approval, release or other authorization is required to satisfy Sellers’ and Buyer’s conditions in Section 8.1 or Section 8.2, a notice of such Person’s refusal to grant such waiver, consent, permit, approval, release or other authorization and such Person’s refusal cannot be remedied or otherwise addressed by the Termination Date;

(c) Sellers may terminate this Agreement by giving written notice to Buyer at any time prior to the Closing if Sellers are unable, using Commercially Reasonable Efforts, to obtain the approval of the shareholders of Ridgewood Electric Power Trust IV and Ridgewood Electric Power Trust V to an equitable adjustment of the Purchase Price as contemplated by Section 11.2(f);

(d) Sellers may terminate this Agreement at any time before obtaining the approval of the shareholders of Ridgewood Electric Power Trust IV and Ridgewood Electric Power Trust V for a Superior Proposal, provided Sellers have complied with Sections 6.10(a) and (d) hereof and Buyer has not matched the terms of such Superior Proposal. In the case that Sellers terminate this Agreement pursuant to this

36

Section 12.1(d), Sellers shall pay to Buyer an amount equal to 5% of the Purchase Price (“Termination Fee”) in accordance with Section 12.2 hereof.

(e) Buyer may terminate this Agreement (i) by giving written notice to Sellers pursuant to Section 11.2(e), or (ii) in case of a willful and material breach by Sellers (directly or indirectly, through any director, officer, or counsel of Sellers) of Section 6.10 (Exclusivity) or (iii) within five (5) business days after the delivery by Buyer to Sellers of a written notice of termination of this Agreement in the event that Sellers commence negotiations or discussions with any third party pursuant to the terms of Section 6.10(c) hereof.

12.2 Effect of Termination.  If any Party terminates this Agreement pursuant to Section 12.1, all rights and obligations of the Parties hereunder shall terminate without any Liability of any Party to the other Parties (except for any Liability of any Party then in breach or any Liability of one Seller to the other and except as otherwise expressly provided herein). Notwithstanding the foregoing, if Sellers terminate this Agreement pursuant to section 12.1(d) or Buyer terminates this Agreement pursuant to Section 12.1(e)(iii), Sellers shall pay to Buyer the Termination Fee, such amount to be payable to Buyer if an Alternate Transaction is closed within one year of such termination, and shall be paid by wire transfer in immediately available funds upon the closing of such Alternate Transaction.

13.   Miscellaneous

13.1 Press Releases and Public Announcements.  No Party shall issue any press release or make any public announcement relating to the subject matter of this Agreement prior to the Closing without first affording the non-disclosing Parties the opportunity to review and comment on such press release or public announcement; provided that any Party may make any public disclosure it believes in good faith is required by applicable law or any listing or trading agreement concerning its publicly-traded securities (in which case the disclosing Party shall provide the other Parties with the opportunity to review in advance the disclosure).

Any assignment in contravention of the foregoing sentence shall be null and void and without legal effect on the rights and obligations of the Parties hereunder. Each Party agrees, at the assigning Party’s expense, to execute and deliver such documents as may be reasonably necessary to accomplish any such permitted assignment, transfer, pledge or other disposition of rights and interests hereunder so long as the nonassigning Party’s rights under this Agreement are not thereby materially altered, amended, diminished or otherwise impaired.

BACKUP CERTIFICATE AGREEMENT

This Backup Certificate Agreement is entered into among Indeck Maine Energy, LLC (“Indeck Maine”), Ridgewood Providence Power Partners, L.P. (“RPPP”), Ridgewood Rhode Island Generation, LLC (“RRIG”), Linwood 0708 LLC (“Linwood”), Rhode Island LFG Genco, LLC (“RILG,” and together with RPPP, RRIG and Linwood, “Backup Purchasers”), and acknowledged and consented to by, solely as to Section 5(b) below, Covanta Energy Corporation (“Covanta”) and Ridgewood Power Management LLC, as agent for Linwood, RPPP and RRIG under the Agreement (as defined below) (“RPM”), as of August 19, 2008 (this “Backup Agreement”). Indeck Maine and Backup Purchasers are referred to herein individually as a “Party” and collectively, as the “Parties.” Capitalized terms not otherwise defined herein have the meanings given to such terms in the Amendment or the Agreement (each defined below).

RECITALS

WHEREAS, under that certain Certificate Purchase and Sale Agreement entered into as of April 30, 2003 by and among Constellation Energy Commodities Group, Inc., f/k/a Constellation Power Source, Inc. (“Constellation”), Indeck Maine, RPPP, RRIG and RPM, as amended by that certain letter agreement dated January 25, 2006 and Amendment No. 1 dated as of October 31, 2006 (the “Previously Effective Agreement”), Indeck Maine, RPPP, RRIG and Linwood agreed to sell Certificates to Constellation;

WHEREAS, under that certain Purchase and Sale Agreement dated as of the date hereof among Ridgewood Maine, L.L.C., Indeck Energy Services, Inc., Covanta and, for certain limited purposes, Indeck Maine (the “Purchase and Sale Agreement”), Ridgewood Maine, L.L.C. and Indeck Energy Services, Inc. shall sell, assign, transfer and convey to Covanta their respective membership interests in Indeck Maine (the “Transaction”);

WHEREAS, under that certain Assignment, Assumption, Release and Amendment to the Agreement dated as of July 31, 2008 (the “Amendment”), Indeck Maine agreed to assign its respective rights and obligations under the Agreement to Linwood and Linwood agreed to assume such rights and obligations as of the Effective Date (as defined below) (the Previously Effective Agreement, as amended by the Amendment, is referred to herein as the “Agreement”);

WHEREAS, as a result of the transactions contemplated by the Agreement, Linwood, RPPP and RRIG are obligated to provide Constellation with the Certificates required for the 2008 Optional Firm Transaction and, if Constellation so elects, the 2009 Optional Firm Transaction;

WHEREAS, in order to fulfill such obligations, Backup Purchasers wish to purchase from Indeck Maine and Indeck Maine wishes to sell to Backup Purchasers certain Second Standard Certificates as contemplated in this Backup Agreement; and

WHEREAS, Indeck Maine has agreed to act as agent (the “Agent”) for Linwood, RPPP and RRIG with respect to Delivery of Second Standard Certificates to Constellation and payments therefor pursuant to that certain Agency Agreement dated as of the date hereof (the “Agency Agreement”) among Indeck Maine, RPM, Linwood, RPPP and RRIG.

NOW, THEREFORE, in consideration of the foregoing and the mutual agreements contained herein, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Parties hereto, intending to become legally bound, agree as follows:

1. This Backup Agreement shall become valid, effective and enforceable as of the date this Backup Agreement is fully executed by all the Parties hereto, provided that Sections 2 through 11 shall be subject to, and not valid, effective or enforceable until, the closing of the Transaction (the “Effective Date”). Subject to and upon the Effective Date, the Parties agree that they will commence the performance of their obligations under Sections 2 through 11 of this Backup Agreement.

2. (a) To the extent Linwood, RPPP and RRIG are permitted pursuant to the terms of the Agreement to provide Constellation with Second Standard Certificates (rather than First Standard Certificates) for 2008 to meet their obligations under the 2008 Optional Firm Transaction, Indeck Maine shall, subject only to Force Majeure, sell, transfer and Deliver to Backup Purchasers and Backup Purchasers shall purchase and take from Indeck Maine, Certificates for MWhs of generation from its biomass generating facilities located in Jonesboro, Maine and West Enfield, Maine, which include (a) Indeck West Enfield (NEPOOL GIS Asset I.D. #445) and (b) Indeck Jonesboro (NEPOOL GIS Asset I.D. #446) (together, the “Biomass Projects”) in 2008 meeting the Second Standards (“Maine Biomass 2008 Generation”), at the times, and in amounts equal to, the Second Standard Certificates otherwise to be Delivered by Linwood, RPPP and RRIG to Constellation under the Agreement for the 2008 Optional Firm Transaction, which will not in any event exceed 208,651 such Certificates (less Certificates Delivered pursuant to the Agreement prior to the Effective Date). Linwood, RPPP and RRIG’s agreed schedule for the delivery of Second Standard Certificates to Constellation, and thus, upon the Effective Date, the expected delivery schedule for Indeck Maine hereunder, with respect to the 2008 Optional Firm Transaction (less Certificates Delivered pursuant to the Agreement prior to the Effective Date) is attached hereto as Exhibit A to this Backup Agreement.

(b) To the extent Linwood, RPPP and RRIG are permitted pursuant to the terms of the Agreement to provide Constellation with Second Standard Certificates (rather than First Standard Certificates) for 2009 to meet their obligations under the 2009 Optional Firm Transaction, Indeck Maine shall, subject only to Force Majeure, sell, transfer and Deliver to Backup Purchasers and Backup Purchasers shall purchase and take from Indeck Maine, Certificates for MWhs of generation from its Biomass Projects in 2009 meeting the Second Standards (“Maine Biomass 2009 Generation”), at the times, and in an amounts equal to, the Second Standard Certificates otherwise to be Delivered by Linwood, RPPP and RRIG to Constellation under the Agreement for the 2009 Optional Firm Transaction, which will not in any event exceed 208,651 such Certificates. Linwood, RPPP and RRIG will provide Indeck Maine with the schedule for the delivery of First and Second Standard Certificates to Constellation, and thus, upon the Effective Date, the expected delivery schedule for Indeck Maine for Second Standard Certificates hereunder, with respect to the 2009 Optional Firm Transaction promptly after Linwood, RPPP and RRIG and Constellation reach agreement upon any such schedule.

(c) Notwithstanding paragraphs (a) and (b) above, solely to the extent Indeck Maine is unable to provide Certificates to Backup Purchasers as required by paragraphs (a) and (b) that have been generated from the Biomass Projects and such failure is not excused as a Force Majeure, Indeck Maine may Deliver Certificates to Backup Purchasers otherwise meeting all of the other terms and conditions of paragraphs (a) and (b) above, but which have not been generated by the Biomass Projects.

(d) For purposes of this Backup Agreement, a Certificate shall only be deemed to be “Delivered” if (1) such Certificate has been created on its “Creation Date” in the NEPOOL GIS and (2) such Certificate has subsequently been deposited in one of Backup Purchasers’ account in the NEPOOL GIS. Title to and risk of loss with respect to the Certificates shall pass to Backup Purchasers upon Delivery of such Certificates to Backup Purchasers as provided herein. Notwithstanding any other provisions of this Section 2 to the contrary, delivery of Certificates to Constellation under the Agency Agreement shall constitute Delivery hereunder.

(e) Backup Purchasers shall pay Indeck Maine the same price for the Certificates to be delivered hereunder as the price Linwood, RPPP and RRIG are entitled to receive (without setoff) from Constellation for such Certificates under the Agreement. Notwithstanding the foregoing, payment of any amount by Constellation to the Agent under the Agency Agreement shall satisfy Backup Purchasers’ payment obligations with respect to that same amount under this Backup Agreement.

(f) Indeck Maine shall be entitled to reduce its obligations to Deliver Certificates under Section 2(a) of this Backup Agreement by the amount equal (without duplication of any reduction) to the Maine Biomass 2008 Generation Certificates actually Delivered under the Agreement prior to or on the Effective Date. For the avoidance of doubt, nothing herein, shall entitle Indeck Maine to receive compensation from Backup Purchasers for any Certificates Delivered to Constellation prior to or on the Effective Date, except to the extent such compensation is part of the Working Capital Payment under the Purchase and Sale Agreement.

2

(g) With respect to each sale and Delivery of Certificates hereunder, Indeck Maine represents, warrants and agrees that it shall convey good and marketable title to such Certificates upon Delivery and will Deliver such Certificates, free and clear of any and all Liens and Claims.

(h) If and to the extent that Constellation sets off any Seller Amount against any Indeck Maine Amount under Section 5.4 of the Agreement and Section 9 of the Amendment and Backup Purchasers have not otherwise paid such set off amount to Indeck Maine under Section 2 hereof, Backup Purchasers shall immediately reimburse Indeck Maine for such set off amount. Backup Purchasers represent and warrant to and agree with Indeck Maine that, except with respect to the obligations of Linwood, RPPP and RRIG under the Agreement and except as provided in Section 9 below, Backup Purchasers have and will have during the term hereof no other agreements, contracts or undertakings with Constellation which could give rise to additional rights of Constellation to so set off against the Indeck Maine Amount.

(i) In event that either Backup Purchasers or Indeck Maine claims the occurrence of a Force Majeure hereunder, the Party claiming that Force Majeure shall have the same rights and obligations and shall be subject to the same restrictions with respect to that Force Majeure as if it were the “Claiming Party” under Section 3.4 and under the definition of “Force Majeure” in Article 10 of the Agreement, and the Party or Parties not claiming that Force Majeure shall have the same rights and obligations, and shall be subject to the same restrictions with respect to that Force Majeure as if it were the “non-Claiming Party” under Section 3.4 and under the definition of Article 10 of the Agreement. Notwithstanding the foregoing, this Backup Agreement may not be terminated as a result of a Force Majeure unless the Agreement has been terminated as a result of the same Force Majeure.

(j) So long as the Agency Agreement is in effect and Agent’s power and authority to act thereunder has not been suspended pursuant to Section 5 of the Agency Agreement, Indeck Maine will Deliver directly to Constellation all of the Second Standard Certificates to be delivered under the Agreement, invoice and receive payment from Constellation and collect payment from Constellation for such Second Standard Certificates (subject to the terms of the Agency Agreement). So long as the Agency Agreement is in effect, Agent’s power and authority to act thereunder has not been suspended pursuant to Section 5 of the Agency Agreement, and Indeck Maine complies with the first sentence of this Section 2(j), Linwood, RPPP and RRIG will not deliver Second Standard Certificates to Constellation under the Agreement (or invoice, receive payment or collect amounts related thereto) in place of the Second Standard Certificates to be delivered by Indeck Maine under Sections 2(a), 2(b) and 2(c) of this Backup Agreement.

(k) RILG consents to the arrangements set forth in the Agency Agreement.

3. (a) As soon as practicable after the end of each calendar month, Indeck Maine will prepare and deliver to Backup Purchasers the invoice and other information (collectively, the “Invoice Information”) required under Section 5.1 of the Agreement for any Certificates Delivered by it under Section 2(a) or 2(b) of this Backup Agreement, which Invoice Information shall be prepared in accordance with Section 5.1 of the Agreement and Section 9 of the Amendment.

(b) All such invoices properly submitted by Indeck Maine to Backup Purchasers pursuant to this Agreement and in accordance with Section 5.1 of the Agreement shall be due and payable by Backup Purchasers in accordance with Indeck Maine’s invoice instructions on or before the later of the twenty-third (23^rd) day of the calendar month in which such invoice was so submitted, and the thirteenth (13^th) day after receipt of the invoice or, if such day is not a Business Day, then on the next Business Day. Each Party will make payments by electronic funds transfer, or by other mutually agreeable method(s), to the account designated by the other Party in Exhibit B hereto. Any amounts not paid by the due date therefor will be deemed delinquent and will accrue interest at the Interest Rate, such interest to be calculated from and including the due date to but excluding the date the delinquent amount is paid in full.

(c) Indeck Maine will comply with the requirements of Section 5.5 of the Agreement with respect to any Invoice Information delivered to Constellation by Indeck Maine.

4. (a) Indeck Maine hereby agrees to retain in its own NEPOOL GIS account Certificates relating to Maine Biomass 2008 Generation, up to 208,651 Certificates (less Certificates Delivered pursuant to the

Agreement prior to the Effective Date) meeting the Second Standards (the “2008 Hold Back”), until the sooner of (x) the date on which Indeck Maine has received written notice from Backup Purchasers indicating that Linwood’s, RPPP’s and RRIG’s obligations to Constellation under the Agreement for the balance of the 2008 Optional Firm Transaction have been satisfied or (y) April 30, 2009; provided Indeck Maine shall be entitled to reduce the amount of its 2008 Hold Back by an amount equal to the Maine Biomass 2008 Generation Certificates actually Delivered under this Backup Agreement as and when such amounts are Delivered. Backup Purchasers shall promptly provide to Indeck Maine written notice of Linwood’s, RPPP’s and RRIG’s satisfaction of the obligations to Constellation under the Agreement for the balance of the 2008 Optional Firm Transaction upon such satisfaction.

(b) Indeck Maine hereby agrees to retain in its own NEPOOL GIS account all Certificates relating to Maine Biomass 2009 Generation, up to 208,651 Certificates meeting the Second Standards (the “2009 Hold Back”), until the sooner of (x) the date on which Indeck Maine has received written notice from Backup Purchasers indicating that Linwood’s, RPPP’s and RRIG’s obligations to Constellation under the Agreement for the balance of the 2009 Optional Firm Transaction have been satisfied or (y) April 30, 2010; provided Indeck Maine shall be entitled to reduce the amount of its 2009 Hold Back by an amount equal to the Maine Biomass 2009 Generation Certificates actually Delivered under this Backup Agreement as and when such amounts are Delivered; and, provided, further, that Indeck Maine’s obligation to hold back up to 208,651 Certificates as the 2009 Hold Back shall be reduced Certificate for Certificate to the extent that Linwood, RPPP and RRIG commit to provide to Constellation greater than 51,349 Certificates in 2009 meeting the First Standards.

(c) Within fifteen (15) days after the end of each calendar quarter, Backup Purchasers and Indeck Maine will provide each other with a report of (i) the number of Certificates Delivered by Linwood, RPPP and RRIG or Indeck Maine, as the case may be, to Constellation either under the Agreement or under the Agency Agreement for the 2008 Optional Firm Transaction and/or for the 2009 Optional Firm Transaction, (ii) the MWhs of generation produced by its respective facilities for the current calendar year through the end of such calendar quarter, and (iii) a good faith forecast of the MWhs of generation it expects its respective facilities to produce for the remainder of the calendar year.

5. (a) Unless excused by Force Majeure (subject to Section 2(i)) or Backup Purchasers’ failure to perform, in the event that Indeck Maine Delivers fewer Certificates than it is required to Deliver hereunder (the number of Certificates that Indeck Maine fails to Deliver being referred to herein as the “Deficiency”), Indeck Maine shall pay to Backup Purchasers an amount equal to the product of (x) the Deficiency and (y) the positive difference, if any, between the price to be paid for each Certificate under the Agreement and the Replacement Price therefor, plus Deficiency Costs incurred by Constellation, plus Backup Purchasers’ reasonable attorneys’ fees, each in connection with such failure. As used in this Section 5(a), “Deficiency Costs” means, without duplication, any brokerage fees, commissions and similar third party transaction costs and expenses reasonably incurred by Constellation either in terminating a Transaction pursuant to which Constellation hedged its obligations or entering into new arrangements which replace such Terminated Transaction, plus all reasonable attorneys’ fees and expenses incurred by Constellation in connection with a Deficiency. The Parties hereby agree that the amounts payable under this Section 5 are the only damages for the failure of Indeck Maine to perform its obligations under this Backup Agreement.

(b) Covanta agrees to deliver to Backup Purchasers promptly upon execution of this Backup Agreement by all of the Parties hereto a guaranty of the obligations of Indeck Maine under this Backup Agreement, with a guaranteed amount not to exceed at any time an amount equal to 80% of the amount required to be funded at such time in the Account under and pursuant to Section 5.2 of the Agreement (but not the amount required with respect to Section 3.6 of the Agreement), but in any event not to exceed a maximum amount of $7,300,000, in the form of Exhibit C attached hereto, which guaranty shall be subject to, and its effectiveness conditioned upon, the Effective Date.

6. Indeck Maine agrees to operate the Biomass Projects so as to maximize the MWhs of generation in respect of which Certificates are to be Delivered under Sections 2(a) and 2(b) above; provided, however, that in no event shall Indeck Maine be required to operate the Biomass Projects in a manner not in accordance

4

with good utility practice and industry standards. Additionally, if the Effective Date occurs on or before September 30, 2008, Indeck Maine shall notify Backup Purchasers not later than September 30, 2008 of Indeck Maine’s forecasted generation at the Biomass Projects during 2009.

7. Subject to and upon the Effective Date, Indeck Maine, without any further action required, shall transfer and assign its entire interest in the Account, including all amounts on deposit in the Account, to Linwood, which transfer is subject to the rights and security interest of Constellation in such interest in the Account.

8. If Constellation fails to exercise its option under the Agreement with respect to the 2009 Optional Firm Transaction by the deadline date therefor in the Agreement, then all provisions of this Agreement related to the 2009 Optional Firm Transaction, and the requirements of Sections 2(b) and 4(b) herein, shall be of no further force and effect.

9. (a) Linwood, RPPP, RRIG and RPM shall not amend or modify any term, condition or covenant of the Agreement unless (i) Linwood, RPPP, RRIG and RPM give Indeck Maine prior written notice of any such proposed amendment or modification, including a copy of the proposed documentation to effect such amendment or modification, and (ii) Linwood, RPPP, RRIG and RPM comply with the following procedures, upon Indeck Maine’s reasonable opportunity to review such notice (together with all necessary and appropriate documentation), which opportunity to review will in no event be longer than ten (10) Business Days after receipt of such notice and all such necessary and appropriate documentation that may be reasonably requested by Indeck Maine:

(1) in the event that Indeck Maine reasonably determines that such proposed amendment or modification of the Agreement could reasonably be expected to have an adverse impact on Indeck Maine’s rights or obligations under any material term, condition or covenant of this Backup Agreement or the Agency Agreement on and after the Effective Date, Linwood, RPPP, RRIG and RPM shall not amend or modify any such material term, condition or covenant of the Agreement having such adverse impact on Indeck Maine without obtaining Indeck Maine’s prior written consent to any such amendment or modification, such consent of Indeck Maine not to be unreasonably withheld, conditioned or delayed; and

(2) in the event that Indeck Maine reasonably determines that clause (1) above does not apply to such proposed amendment or modification of the Agreement and that such proposed amendment or modification could reasonably be expected to materially reduce the contractual incentives or remedies for performance of any terms, conditions or covenants of Linwood, RPPP, RRIG under the Agreement on and after the Effective Date (including any reduction in or modification to collateral, terms of guaranties or other security arrangements other than an immaterial reduction in or modification to collateral, terms of guaranties or other security arrangements), Linwood, RPPP, RRIG and RPM shall not amend or modify any such term, condition or covenant of the Agreement without providing to Indeck Maine, prior to execution of the first such amendment or modification, a one-time cash deposit in the amount of $6,000,000 (the “Escrow Deposit”) to be held as collateral security pursuant to the Escrow Agreement dated as of the date hereof among Indeck Maine, Backup Purchasers and Capital One, N.A., as escrow agent (the “Escrow Agreement”) to secure the performance of Backup Purchasers under this Backup Agreement and the Agency Agreement. The Escrow Deposit will be held in an interest-bearing bank account and may be drawn on by Indeck Maine to the extent that Backup Purchasers fail to make any payment as and when due pursuant to the terms of this Backup Agreement or the Agency Agreement. Upon the expiration or termination of this Backup Agreement, all amounts in the Escrow Deposit (include all interest earned on amounts therein) at such time will be released to Backup Purchasers absent any pending obligation of the Backup Purchasers or any claim by Indeck Maine under the Escrow Agreement.

(b) Linwood, RPPP and RRIG represent, warrant and agree to comply with the terms and conditions of the Agreement at all times during the term of the Backup Agreement.

(c) During the term hereof, Backup Purchasers shall promptly provide to Indeck Maine a written copy of any notice or other communication received from or delivered to Constellation pursuant to the terms and conditions of the Agreement, including, without limitation, any and all (i) invoices delivered by Linwood,

5

RPPP and RRIG to Constellation, (ii) notices from Constellation related to the amount or timing of any requests for Delivery of Certificates meeting either First or Second Standards, (iii) Constellation’s exercise of its option under the Agreement with respect to the 2009 Optional Firm Transaction, or (iv) notice from or to Constellation of breach, default or termination.

(d) Upon the reasonable request of either Party, the other Party shall provide to the requesting Party all reasonable documentation and information related to the administration and/or performance of the Agreement, this Backup Agreement and the Agency Agreement. The Parties further agree to provide to each other audit rights regarding the administration and performance of the Agreement and the Backup Agreement equivalent to the audit rights set forth in Section 5.5 of the Agreement. In furtherance of the purposes of this Section, Indeck Maine may reasonably direct Linwood, RPPP and RRIG to exercise their rights to audit the records of Constellation with respect to any Certificates and “Invoice Information” provided by Agent directly to Constellation under the Agency Agreement or to Backup Purchasers hereunder and to provide Agent with reasonable access to the information obtained with respect to such Certificates and Invoice Information, subject to the confidentiality provisions of Section 9.4 of the Agreement.

10. This Backup Agreement shall terminate upon any termination of the Agreement unless such termination of the Agreement was caused by a breach or default of Linwood, RPPP or RRIG thereunder.

Attn: Randall D. Holmes

Ladies and Gentlemen:

For value received, Covanta Energy Corporation (the “Guarantor”), a corporation duly organized under the laws of Delaware, unconditionally and absolutely guarantees to Ridgewood Providence Power Partners, L.P. (“RPPP”), Ridgewood Rhode Island Generation, LLC (“RRIG”), Linwood 0708 LLC (“Linwood”) and Rhode Island LFG Genco, LLC (“RILG” and together with RRIG, RPPP and Linwood, the “Counterparties”), the prompt and complete payment when due, whether by acceleration or otherwise, of all payment obligations and liabilities (the “Guaranteed Obligations”), whether now in existence or hereafter arising, of Indeck Maine Energy, LLC, a limited liability company duly organized under the laws of the State of Illinois (together with its successors, the “Company”), pursuant to that certain Backup Certificate Agreement, dated on the date hereof, among the Company, RPPP, RRIG, Linwood, RILG and Ridgewood Power Management LLC, as agent for RPPP, RRIG and Linwood under the Agreement (defined below) (the “Backup Agreement”). Each capitalized term used but not defined herein shall have the meaning given to it in the Backup Agreement.

This Guaranty is one of payment and not of collection. Notwithstanding anything to the contrary, the total liability of Guarantor hereunder, regardless of any amendment or modification to the Backup Agreement, shall not exceed at any time an amount equal to 80% of the amount required to be funded at such time in the Account (as defined in the Agreement as defined below) under and pursuant to Section 5.2 of the Certificate Purchase and Sale Agreement dated as of April 30, 2003 among the Company, RPPP, RRIG, Ridgewood Power Management LLC as agent (“RPMC”) and Constellation Energy Commodities Group, Inc., f/k/a Constellation Power Source, Inc. (“Constellation”), as amended by that certain letter agreement dated January 25, 2006, by Amendment No. 1 thereto dated as of October 31, 2006 and by the Assignment, Assumption, Release and Amendment Agreement of Certificate Purchase and Sale Agreement, among Constellation, the Company, RPPP, RRIG, RPMC, Ridgewood Electric Power Trust III, Ridgewood Electric Power Trust IV, Ridgewood Electric Power Trust V, Ridgewood Power B Fund/Providence Expansion and Linwood, dated as of July 31, 2008 (together the “Agreement”), but not the amount required with respect to Section 3.6 of the Agreement, but in any event not to exceed a maximum amount of $7,300,000 (the “Liability Cap”). For the avoidance of doubt, the Guaranteed Obligations may at any time and from time to time exceed the liability of the Guarantor hereunder without impairing this Guaranty. The Guarantor’s obligations and liability under this Guaranty shall be limited to payment obligations only, and the Guarantor shall have no obligation to perform (other than payment of this Guaranty) under the Backup Agreement, including no obligation to generate, obtain or provide Certificates.

The Guarantor hereby waives notice of acceptance of this Guaranty and notice of any obligation or liability to which it may apply, and waives presentment, demand for payment, protest, notice of dishonor or non-payment of any such obligation or liability, suit or the taking of other action by the Counterparties against, and any other notice to, the Company, the Guarantor or others.

The Counterparties, at any time and from time to time without notice to or consent of the Guarantor and without impairing or releasing the obligations of the Guarantor hereunder, may, with respect to the Guaranteed Obligations: (1) agree with the Company to make any change in the terms of any obligation or liability of the Company to the Counterparties, (2) take or fail to take any action of any kind in respect of any security for any obligation or liability of the Company to the Counterparties, (3) exercise or refrain from exercising any rights against the Company or others, or (4) compromise or subordinate any obligation or liability of the Company to the Counterparties including any security therefor. Any other suretyship defenses are hereby waived by the Guarantor.

This Guaranty shall be subject to and only effective on and after the closing of the transactions contemplated in the Purchase and Sale Agreement, dated as of the date hereof, between Ridgewood Maine, L.L.C. (“RM”), Indeck Energy Services (“IES”) and Guarantor, pursuant to which RM and IES shall sell, assign, transfer and convey to Guarantor their respective membership interests in the Company. This Guaranty shall continue in full force and effect until the later of (A) the termination or expiration of the Backup Agreement and (B) the satisfaction of all of the Company’s obligation under the Backup Agreement and the Guarantor’s obligations under this Guaranty.

This Guaranty shall continue to be effective or be reinstated, as the case may be, if at any time any payment of any of the Guaranteed Obligations are annulled, set aside, invalidated, declared to be fraudulent or preferential, rescinded or must otherwise be returned, refunded or repaid by the Counterparties upon the insolvency, bankruptcy, dissolution, liquidation or reorganization of the Company or any other guarantor, or upon or as a result of the appointment of a receiver or conservator of, or trustee for the Company or any other guarantor or any substantial part of its property or otherwise, all as though such payment or payments had not been made. To the extent that any payment by the Guarantor hereunder is annulled, set aside, invalidated, declared to be fraudulent or preferential, rescinded or must otherwise be returned, refunded or repaid by the Counterparties, the amount available under the Liability Cap will be restored by an amount equal to such payment.

The Guarantor may not assign its rights nor delegate its obligations under this Guaranty, in whole or in part, without prior written consent of the Counterparties, and any purported assignment or delegation absent such consent is void, except for an assignment and delegation of all of the Guarantor’s rights and obligations hereunder in whatever form the Guarantor determines may be appropriate to a partnership, corporation, trust or other organization in whatever form that succeeds to all or substantially all of the Guarantor’s assets and business and that assumes such obligations by contract, operation of law or otherwise. Upon any such delegation and assumption of obligations (including any obligations arising prior to such delegation and assumption), the Guarantor shall be relieved of and fully discharged from all obligations hereunder, whether such obligations arose before or after such delegation and assumption.

THIS GUARANTY SHALL BE GOVERNED BY AND CONSTRUED IN ACCORDANCE WITH THE INTERNAL LAWS OF THE STATE OF NEW YORK WITHOUT GIVING EFFECT TO PRINCIPLES OF CONFLICTS OF LAW. GUARANTOR AGREES TO THE EXCLUSIVE JURISDICTION OF COURTS LOCATED IN THE STATE OF NEW YORK, UNITED STATES OF AMERICA, OVER ANY DISPUTES ARISING UNDER OR RELATING TO THIS GUARANTY.

Very truly yours,

COVANTA ENERGY CORPORATION

WHEREAS, the Amended and Restated Operating Agreement of Indeck Maine Energy, L.L.C. made as of June 11, 1997 (the “IME Operating Agreement”), sets forth the rights and responsibilities of the members of IME (in such context, each an “IME Member” and collectively, the “IME Members”) with respect to IME and their respective membership interests therein (collectively, the “IME Membership Interests”); and

WHEREAS, the Managing Shareholder is the managing shareholder of certain business trusts formed under the laws of Delaware (the “Trusts”), some of which are the members and owners of RM; and

WHEREAS, RM has loaned funds to IME in the aggregate principal amount of $8,150,000 plus accrued interest thereon pursuant to a series of promissory notes issued from time to time by IME and currently held by RM (the “RM Promissory Notes”) and IES and its predecessors have loaned funds to IME in the aggregate principal amount of $8,150,000 plus accrued interest thereon pursuant to a series of promissory notes issued from time to time by IME and currently held by IES (the “IES Promissory Notes” and together with the RM Promissory Notes, the “Promissory Notes”), which Promissory Notes are listed on Schedule 1 hereto; and

WHEREAS, RM and IES wish to set forth certain agreements between them regarding the Proposed Transaction and other related corporate matters.

NOW, THEREFORE, in consideration of the foregoing and the mutual agreements contained herein, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto, intending to become legally bound, agree as follows:

1.  Amendment of Original Agreement and IME Operating Agreement.  

(a) This Agreement supercedes the Original Agreement, which is amended and restated in its entirety by this Agreement and which Original Agreement is of no further force or effect.

(b) This Agreement constitutes an amendment of the IME Operating Agreement in accordance with Section 13.2 thereof to the extent that the terms and provisions hereof modify any terms and provisions of the IME Operating Agreement as in existence prior to the execution and delivery hereof.

2.  Creation of Senior Preferred Membership Units; Contribution of Promissory Notes.  

(a) The parties agree that IME shall hereby authorize a new class of membership interests in IME called “Senior Preferred Membership Interests,” which shall be denominated in units and issued by the Managing Shareholder in accordance with the provisions of this Agreement. The units of Senior Preferred Membership Interests (the “Senior Preferred Membership Units”) shall initially consist of 1,000 authorized units. The holders of Senior Preferred Membership Units shall be entitled to preferred allocations of distributions from IME as further described in Section 7 of this Agreement.

(b) Effective as of the date that is three days prior to the scheduled closing date of the Proposed Transaction (the “Contribution Date”), RM shall contribute the RM Promissory Notes to IME in exchange for the issuance to RM of 500 Senior Preferred Membership Units (the “RM Senior Preferred Units”), which Senior Preferred Membership Units shall have an aggregate fair market value equal to the aggregate amount of principal and accrued interest under the RM Promissory Notes as of the Contribution Date.

(c) Effective as of the Contribution Date, IES shall contribute the IES Promissory Notes to IME in exchange for the issuance to IES of 500 Senior Preferred Membership Units (the “IES Senior Preferred Units”), which Senior Preferred Membership Units shall have an aggregate fair market value equal to the aggregate amount of principal and accrued interest under the IES Promissory Notes as of the Contribution Date.

(d) The Senior Preferred Membership Units issued to each of RM and IES hereunder shall not be certificated, but shall be reflected in the records of IME.

(e) The Managing Shareholder shall provide RM and IES with notice of the occurrence of the Contribution Date at least two business days prior thereto. On the Contribution Date, RM shall deliver all of the RM Promissory Notes in its possession to IME, duly endorsed for transfer to IME, and shall provide an affidavit and indemnity, reasonably acceptable to the Managing Shareholder, with respect to any RM Promissory Notes no longer in RM’s possession. On the Contribution Date, IES shall deliver all of the IES Promissory Notes in its possession to IME, duly endorsed for transfer to IME, and shall provide an affidavit and indemnity, reasonably acceptable to the Managing Shareholder, with respect to any IES Promissory Notes no longer in IES’s possession. IME will cancel the Promissory Notes upon its receipt of the Promissory Notes or indemnity and affidavits with respect thereto, and issuance of the Senior Preferred Membership Units.

3.  IME Membership Interests.  Each of RM and IES represents and warrants to the other that, including the transactions contemplated in Section 2 hereto:

(a) such party is the record and beneficial owner and has good and valid title to the IME Membership Interests in its name as set forth on Schedule 2, free and clear of all Liens (as defined in the PSA or an Alternate Definitive Agreement) as of the date hereof and constitute all of such party’s direct and indirect right, title and interest in or to the Company; and

(b) to the best knowledge of such party, the information concerning the IME Membership Interests set forth in Schedule 2 hereto is true, complete and accurate, and reflects all of the equity interests and proprietary interests in the two biomass-fueled electricity generation projects located in the State of Maine owned by and operated by IME (the “Projects”) since the inception of the Projects.

4.  Representation with Respect to PSA or Alternative Definitive Agreement.  RM and IES agree that the Managing Shareholder is authorized to represent and act on behalf of RM and IES in connection with the preparation of the Purchase and Sale Agreement dated as of the date hereof (as amended from time to time in accordance with the terms hereof, the “PSA”) among RM, IES and Covanta Energy Corporation (“Covanta”) or of another definitive agreement reflecting a Superior Proposal (as defined in the PSA) (such other definitive agreement being referred to herein as the “Alternate Definitive Agreement”) to be executed by IES and RM (or entities directly or indirectly owned by the Trusts) as sellers (the “Sellers” and individually a “Seller”) and the buyer or buyers in such Superior Proposal; provided, that except as referenced herein, the Alternate Definitive Agreement will not contain terms that materially distinguish between RM as a Seller on the one hand and IES as a Seller on the other with respect to the sale of the IME Membership Interests except in the

2

case of such terms that are more adverse to RM as compared to IES. The Managing Shareholder will provide IES with weekly updates on the status of the negotiation and preparation of the PSA or the Alternate Definitive Agreement and, upon the execution of the PSA or the Alternate Definitive Agreement, the preparation for the closing of the transaction contemplated therein.

5.  Approval of PSA or Alternate Definitive Agreement.  

(a) IES approves the PSA in the form presented to it on the date hereof and is executing and delivering the PSA simultaneously with its execution of this Agreement. Once IES signs the PSA, any changes adverse to IES in the price and other material terms regarding the proposed sale of the IME Membership Interests by IES, as set forth in the PSA, shall be subject to the prior written consent of IES, and shall not be subsequently modified or amended in such manner without the specific prior written consent of IES. Without limiting the foregoing, the Managing Shareholder acknowledges that any such adverse changes to the price, the timing or type of payment, the conditions precedent to receiving payment, and the obligations of IES regarding the sale of its IME Membership Interests pursuant to the PSA are material and shall require IES’ specific prior written consent.

(b) In the event that the Proposed Transaction is not consummated pursuant to the PSA and the Managing Shareholder prepares an Alternate Definitive Agreement, at such time as the Alternate Definitive Agreement is in its final form, it shall be promptly delivered to IES for the purpose of review and execution by IES of the Alternate Definitive Agreement. Should IES fail to execute the Alternate Definitive Agreement within 5 business days after such receipt of the proposed Alternate Definitive Agreement, IES shall not participate in the Proposed Transaction. Once IES signs the Alternate Definitive Agreement, any changes adverse to IES in the price and other material terms regarding the proposed sale of the IME Membership Interests by IES, as set forth in the Alternate Definitive Agreement, shall be subject to the prior written consent of IES, and shall not be subsequently modified or amended in such manner without the specific prior written consent of IES. Without limiting the foregoing, the Managing Shareholder acknowledges that any such adverse changes to the price, the timing or type of payment, the conditions precedent to receiving payment, and the obligations of IES regarding the sale of its IME Membership Interests pursuant to the Alternate Definitive Agreement are material and shall require IES’ specific prior written consent.

6. Participation by RM.  IES hereby acknowledges the right and authority of the Managing Shareholder to cause RM to be included in the Proposed Transaction without regard to the participation (or lack thereof) of IES in the Proposed Transaction. For the avoidance of doubt, should IES fail to execute the Alternate Definitive Agreement pursuant to Section 5 or fail for any other reason to participate in the Proposed Transaction, IES acknowledges that the Managing Shareholder may include the IME Membership Interests owned by RM in the Proposed Transaction thereby transferring the IME Membership Interests owned by RM to Covanta, a subsidiary of Covanta or any other buyer or buyers without further obligation or liability to IES or need for approval from IME, and IES consents to the admission of Covanta, a subsidiary of Covanta or such other buyer or buyers as members of IME in such event. The Managing Shareholder and RM shall have no liability to IES respecting IES’ determination whether to participate in the Proposed Transaction and IES acknowledges that it is conducting and has conducted its own due diligence with respect to the sale of its IME Membership Interests and is not relying on RM or the Managing Shareholder.

7. Allocation of Proceeds.  In the event the transaction set forth in the PSA or an Alternate Definitive Agreement closes and IES participates therein by selling its IME Membership Interests, and notwithstanding anything in the IME Operating Agreement to the contrary, the proceeds of the transaction attributable to the sale of the IME Membership Interests shall be allocated between RM and IES and paid or utilized as set forth in this Section 7. The parties intend such proceeds shall be disbursed promptly at the closing of such sale (the date of such disbursement being the “Disbursement Date”), except to the extent an Alternate Definitive Agreement provides for holdbacks, escrows or the like of a portion of the sale proceeds (the “Holdback”). Unless an Alternate Definitive Agreement expressly provides otherwise, the portion of the Holdback attributable to the sale of the IME Membership Interests shall be not more than the product of (i) a fraction, in which the numerator is the gross proceeds receivable from the sale of IME Membership Interests pursuant to such Alternate Definitive Agreement, and the denominator is the aggregate gross proceeds receivable from the sale

3

of all the assets sold pursuant to such Alternate Definitive Agreement (excluding the effect of any Holdbacks in each case), multiplied by (ii) the aggregate Holdback required under such Alternate Definitive Agreement. Sale proceeds subject to any Holdback which are allocated to the sale of the IME Membership Interests shall be distributed when and as provided in such Alternate Definitive Agreement. The proceeds of the transaction and any Holdback attributable to the sale of the IME Membership Interests shall be allocated among RM and IES and paid as follows:

FIRST, to the payment of Transaction Costs (as defined below) attributable to the sale of the IME Membership Interests, allocated fifty-five percent (55%) from the proceeds otherwise to be received by RM and forty-five percent (45%) from the proceeds otherwise to be received by IES;

SECOND, to RM and IES as the holders of the Senior Preferred Membership Units pro rata up to the fair market value of such units as of the Contribution Date as determined in accordance with Section 2 hereof;

THIRD, all remaining proceeds will be paid fifty-five percent (55%) to RM and forty-five percent (45%) to IES.

8. Transaction Costs.  For purposes of this Agreement, the term “Transaction Costs” shall mean the sum of (a) the portion of the total investment banking fees and expenses payable to Ewing Bemiss & Co. arising from a sale pursuant to the PSA or an Alternate Definitive Agreement attributable to the sale of the IME Membership Interests which shall be deemed equal to the product of (i) a fraction in which the numerator is the gross proceeds receivable from the sale of IME Membership Interests in the Proposed Transaction and the denominator is the aggregate gross proceeds receivable from the sale of all the assets sold in the Proposed Transaction (including any Holdbacks in each case), multiplied by (ii) the aggregate Ewing Bemiss & Co. costs, fees and expenses paid plus (b) an amount equal to 1.5% of the gross proceeds receivable from the sale of the IME Membership Interests in the Proposed Transaction. The Managing Shareholder will cause to be disbursed from the gross proceeds paid by Covanta, a subsidiary of Covanta or another buyer or buyers of the IME Membership Interests, the amounts due to Ewing Bemiss & Co. as described in this Section 8 part (a), as allocated in Section 7 above. The Managing Shareholder will also disburse from the gross proceeds paid by Covanta, a subsidiary of Covanta or another buyer or buyers of the IME Membership Interests, the amounts described in this Section 8 part (b), as allocated in Section 7 above, to third parties in satisfaction of transaction cost incurred in furtherance of the Proposed Transaction.

9. Cross-Indemnification.  

(a) IES hereby agrees to indemnify, defend and save harmless RM, its members, managers, employees, officers, directors, representatives, successors and assigns (collectively “RM Indemnitees”) from and against any and all Losses (as defined in the PSA) incurred by RM following the Closing (as defined in the PSA) accruing, resulting or arising in connection with any breach by IES of Section 4.2 of the PSA except to the extent that such Losses result directly from the gross negligence or willful misconduct of the RM Indemnitees.

(b) RM and the Managing Shareholder hereby jointly and severally agree to indemnify, defend and save harmless IES, its members, managers, employees, officers, directors, representatives, successors and assigns (collectively “IES Indemnitees”) from and against any and all Losses (as defined in the PSA) incurred by IES following the Closing (as defined in the PSA) accruing, resulting or arising in connection with any breach by RM of Section 4.2 of the PSA except to the extent that such Losses result directly from the gross negligence or willful misconduct of the IES Indemnitees.

(c) If this Agreement or any portion hereof is invalidated on any ground by any court of competent jurisdiction, the parties shall nevertheless indemnify each other to the extent permitted by any applicable portion of this Agreement that has not been invalidated by any other applicable law.

(d) The provisions of this Agreement shall survive for same period of time during which the buyer or a buyer related party may make an indemnification claim against IME pursuant to the PSA or Alternate Definitive Agreement.

10. Consent and Waiver.  To the extent required by the IME Operating Agreement, each of RM and IES consents to the sale of the IME Membership Interests of the other pursuant to the PSA or an Alternate

4

Definitive Agreement and waives any rights it may have to acquire such IME Membership Interest in connection with such sale or otherwise restrict the transfer thereof.

11. Termination.  Either party hereto may terminate this Agreement by one (1) day’s prior written notice to the other party hereto (with a copy to the Managing Shareholder) if the Proposed Transaction has not occurred by March 31, 2009; provided, however, that once the PSA or an Alternate Definitive Agreement is executed by the parties hereto and so long as the PSA or an Alternate Definitive Agreement continues to be in effect, this Agreement may not be terminated.

12. Entire Agreement.  Subject to the applicable provisions of the IME Operating Agreement, this Agreement constitutes the entire agreement among the parties with respect to its subject.

13. Agreements for Costs.  The Managing Shareholder represents that it has not entered into (i) any agreement that obligates IME to pay any cost, debt or liability in contravention of the IME Operating Agreement or (ii) any agreement other than the PSA or an Alternate Definitive Agreement and any “Ancillary Agreements” described therein with Covanta or any buyer in a Superior Proposal that reduces the purchase price to be paid for the IME Membership Interests in order to pay the costs, debts or liabilities of any entity other than IME and undertakes that it will not enter into any such agreements.

14. Miscellaneous.  This Agreement shall be governed and construed in accordance with the laws of the State of New York. This Agreement may be executed in several counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument. Each party shall execute such documents and give such assurances as shall be reasonably necessary to perform its obligations hereunder. Notices hereunder shall be given as provided in the IME Operating Agreement. This Agreement may be amended only by an instrument in writing duly executed by the parties hereto. Neither this Agreement, nor any portion, right nor obligation hereunder, may be assigned by either party, but this Agreement shall be binding on any successor in ownership to any of the IME Membership Interests prior to the closing of the PSA or an Alternate Definitive Agreement so long as this Agreement is in effect. IES agrees to cooperate with RM and the Managing Shareholder in connection with the negotiation, execution and closing of the Proposed Transaction, shall not unreasonably withhold or delay its execution and delivery of the PSA or an Alternate Definitive Agreement, agrees to execute and deliver the PSA or an Alternate Definitive Agreement if it complies with the terms of this Agreement and to execute and deliver any other document reasonably necessary or appropriate to consummate the Proposed Transaction. During the term of this Agreement, each of RM and IES agrees not to sell, transfer, pledge or otherwise dispose of any IME Membership Interests or Promissory Notes owned by it, except pursuant to this Agreement and the PSA or an Alternate Definitive Agreement. In the event of a conflict between this Agreement and the PSA or an Alternate Definitive Agreement, this Agreement shall govern.

RECITALS

WHEREAS, each of Indeck Maine Energy, LLC (“Indeck Maine”), RRIG and RPPP are parties to a certain Certificate Purchase and Sale Agreement with Constellation Energy Commodities Energy Group, Inc.

WHEREAS, the parties to the Initial Certificate Purchase Agreement, the Trusts and others have entered into an Assignment, Assumption, Release and Amendment dated as of the date hereof with respect to the Initial Certificate Purchase Agreement (the “Amendment”) (the Initial Certificate Purchase Agreement, as amended and modified by the Amendment, is referred to herein as the “Certificate Purchase Agreement”);

WHEREAS, the members of Indeck Maine, Ridgewood Maine, L.L.C. (“RM”) and IES, intend to sell, assign, transfer and convey to Covanta Energy Corporation (“Covanta”) their respective membership interests in Indeck Maine (the “Transaction”);

WHEREAS, RRIG, RPPP, Linwood, RILG and Indeck Maine expect to enter into a Backup Certificate Agreement (the “Backup Agreement”) pursuant to which, among other things, Indeck Maine will sell certain Certificates to RPPP, RRIG, Linwood and RILG and will transfer and assign all of its interest in the Account, including any funds of Indeck Maine on deposit in the Account (the “Indeck Maine Deposit”), to Linwood, subject to the rights and security interest of Constellation in such interest in the Account, in each case effective upon the closing of the Transaction (the “Transaction Effective Date”);

WHEREAS, RRIG, RPPP, Linwood and Indeck Maine expect to enter into an Agency Agreement (the “Agency Agreement”) pursuant to which, among other things, RRIG, RPPP and Linwood will appoint Indeck Maine as their agent to deliver certain Certificates to Constellation and to invoice and collect amounts due with respect to those Certificates, effective upon the closing of the Transaction Effective Date; and

WHEREAS, the Parties wish to memorialize their respective rights and obligations with respect to the Account, the Certificate Purchase Agreement and the other matters described in this Agreement.

NOW, THEREFORE, in consideration of the premises and the mutual representations, warranties, covenants and agreements set forth in this Agreement, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, and intending to be legally bound, the Parties agree 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, 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 Linwood, RPPP and RRIG under the Certificate Purchase Agreement as of and after the Transaction Effective Date. The respective interests of the Trusts, either directly or through their direct or indirect ownership of RPPP, RRIG, Indeck Maine or Linwood, in the New Deposit Amount as of the date hereof unless and until the Transaction Effective Date occurs are set forth on Schedule 1.

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) Linwood, 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). To the extent that, as a result of that reallocation, a Trust or IES is required to pay an additional amount (as set forth on Schedule 2(b)), 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 (as 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 interests of the Trusts and IES in the Account as set forth on Schedule 1 and Schedule 2(b) apply regardless of where legal title to the New Deposit Amount may reside and are subject to the rights and security interests of Constellation in such interests.

3. Matters Related to Backup Agreement.  If any Party receives notice from Indeck Maine that any payment is due under the Backup Agreement, that Party will promptly provide a copy of that notice to RRP. Within one (1) business day of receiving that notice, RRP will provide the Parties a written notice stating the reason or reasons such payment is due, the basis for that determination and the allocation of responsibility for that payment under this Section 3. If any Party disputes the contents of such notice, such Party will notify RRP and the other Parties in writing of such dispute (including a detailed description of the basis of that dispute) within one (1) business day of its receipt of RRP’s notice. If RRP receives such a dispute notice, it will issue a final determination of the reason the payment is due under the Backup Agreement, and the allocation of responsibility for the payment under this Section 3, taking such Party’s dispute into consideration; provided, however, that RRP has the right to resolve such dispute in the manner RRP deems appropriate. Within two (2) business days of their receipt of a notice from RRP as described in this paragraph (or a final notice if any Party disputes the initial notice), the Parties will make the payments due under the Backup Agreement as follows:

(a) To the extent that any payment is due to Indeck Maine under the Backup Agreement as a result of Constellation exercising its netting and set-off rights under Section 5.4 of the Certificate Purchase Agreement, among RPPP, RRIG and Linwood, the Party or Parties responsible for such set-off or netting rights exercised by Constellation will make such payment directly to Indeck Maine, as directed by RRP.

2

(b) To the extent that any payment is due to Indeck Maine for Certificates delivered under the Backup Agreement, Linwood will be responsible for 100% percent of each such payment, provided that Linwood will obtain all rights all other Parties have against Constellation with respect to that payment, and they shall cooperate with Linwood in that regard. For the avoidance of doubt, this paragraph (b) will not apply to any netting or set-off payment under Section 5.4 of the Certificate Purchase Agreement, which is addressed in Section 3(a) above.

(c) To the extent that any deposit is required to be made in the Escrow Deposit pursuant to Section 9 of the Backup Agreement and pursuant to the analogous provision of Section 6.16 of the Purchase and Sale Agreement among Covanta, RM, IES and Indeck Maine, RPPP and RRIG will share in the responsibility for such payment in a ratio of 27.23% and 72.77% respectively. Any funds that are released from such Escrow Deposit to RPPP, RRIG, Linwood or RILG (including any interest on funds in the Escrow Deposit) after settlement of any claims with respect thereto will be held in trust for the benefit of RRIG and RPPP and shall be promptly allocated and paid over to RPPP and RRIG in the same proportions as set forth in the preceding sentence.

(d) To the extent RRP determines that any payment is due to Indeck Maine under the Backup Agreement or the Agency Agreement as a result of a breach by any of RPPP, RRIG, Linwood or RILG of its obligations under the Backup Agreement or (other than with respect to RILG) the Agency Agreement, RPPP, RRIG and/or Linwood will be responsible for 100% of such payment to the extent to which of RPPP, RRIG, Linwood or RILG breached those obligations, as determined by RRP.

(e) To the extent that any payment is due to Indeck Maine under the Backup Agreement or the Agency Agreement other than as described in Sections 3(a), 3(b), 3(c) or 3(d), RPPP, RRIG and Linwood will share in the responsibility for each such payment in the following amounts: RPPP will be responsible for 5% of each such payment; RRIG will be responsible for 15% of each such payment; and Linwood will be responsible for 80% of each such payment.

(f) To the extent that any of Linwood, RPPP or RRIG receives payment from Constellation that reimburses it for payments made by it under the Backup Agreement, the recipient(s) of such payment shall hold that payment in trust for the benefit of the others not receiving that payment and will promptly allocate and pay over that payment to each of such others according to the payments made by them to Indeck Maine to which such payment from Constellation relates, all as determined by RRP. To the extent any such payment from Constellation cannot be attributed to one or more specific payments to Indeck Maine, such payment shall be allocated among RPPP, RRIG and Linwood according to the percentages in Section 3(e).

(g) To the extent that RILG obtains any right, title or interest in any Certificate Delivered under the Backup Agreement, RILG conveys all such right, title and interest to RPPP, RRIG and Linwood.

4. Matters Related to Certificate Purchase Agreement.  

(a) To the extent that any Party incurs any liability, damages, assessments, taxes, losses, fines, penalties, expenses, fees, costs, and amounts paid in settlement (including reasonable consultants’, attorneys’ and expert witness fees and disbursements in connection with investigating, defending or settling any action or threatened action) in connection with a default under the Certificate Purchase Agreement, including Losses (defined below) incurred under any Guarantee and/or any Security Agreement (including without limitation any Losses resulting from Constellation drawing any amounts out of the Account, realizing on any Collateral provided under any Security Agreement or demanding payment under any Guarantee but, for the avoidance of doubt, not including any liability, damages, assessments, taxes, losses, fines, penalties, expenses, fees, costs, and other amounts incurred in connection with the Backup Agreement, which are addressed in Section 3) (collectively, the “Losses”), that Party will promptly notify RRP in writing of such Loss, including with such notice any information provided by Constellation with respect to that Loss. RRP will provide the Parties a written notice stating the reason or reasons for such Loss, the basis for that determination and the allocation of responsibility for that payment under this Section 4. If any Party disputes the contents of such notice, such Party will notify RRP and the other Parties in writing of such dispute (including a detailed description of the basis of that dispute) within one (1) business day of its receipt of RRP’s notice. If RRP receives such a dispute notice, it

3

will issue a final determination of the reason the payment is due under the Backup Agreement, and the allocation of responsibility for the payment under this Section 4, taking such Party’s dispute into consideration; provided, however, that RRP has the right to resolve such dispute in the manner RRP deems appropriate. Within two (2) business days of their receipt of a notice from RRP as described in this Section 4(a) (or a final notice if any Party dispute the initial notice), the Parties will reimburse the Party or Parties incurring the Loss as follows:

(i) for all Losses determined by RRP to have resulted directly from a breach by a Party of its obligations under the Certificate Purchase Agreement, any Guaranty or any Security Agreement, the Party responsible for that breach will reimburse the Party incurring those Losses for 100% of those Losses; and

(ii) for all Losses determined by RRP to have resulted from a failure of Indeck Maine to perform its obligations under the Backup Agreement, Linwood will reimburse the Party incurring those Losses for 100% of those Losses; provided that Linwood will obtain all rights all other Parties have against Indeck Maine with respect to those Losses, and they shall cooperate with Linwood in that regard.

(b) If and to the extent any Loss involves a withdrawal by Constellation of any amount on deposit in the Account, RRP will determine the Party or Parties responsible for replacing the amount of that withdrawal according to the principles set forth in Section 4(a) above; provided that, for the avoidance of doubt, IES shall not be responsible for replacing the amount of any such withdrawal. To the extent that any Party fails to make a required deposit in the Account under this Section 4(b) within the time period such deposit is required to be made under the Certificate Purchase Agreement, the other Parties may, make such deposit, or cause such deposit to be made, in the Account (a “Step-up Deposit”), and the Party failing to make its required deposit shall promptly reimburse the other Party or Parties that made such Step-up Deposit, with interest accruing on that Step-up Deposit at the Interest Rate.

(c) If any Party receives payment from an entity other than another Party for any Loss, including without limitation any payment by Covanta under its guarantee of Indeck Maine’s obligations under the Backup Agreement, the Party receiving that payment will reimburse each other Party for the amount of that payment (including any deposit that any Party has made in the Account under Section 4(b) above) up to the full amount of the payment received by such other Party.

(d) Capitalized terms used in this Section 4 that are not otherwise defined in this Agreement have the meanings given to them in the Certificate Purchase Agreement.

5. Losses from Linwood Interest.  To the extent that Trust IV incurs any Losses (including without limitation with respect to any taxes) solely and directly as a result of its membership interest in Linwood, Trust V will indemnify and hold harmless Trust IV for 50% of all such Losses.

6. Limitation on Liability.  RRP will have no liability to any Party hereunder for any loss suffered by such Party that arises out of any action or inaction of RRP if RRP, in good faith, determined that such course of conduct was reasonable and such course of conduct did not constitute bad faith, gross negligence or willful misconduct of RRP.

7. Release of Deposit from Constellation.  Each Party agrees that (a) any payment received by it from time to time from Constellation from the New Deposit Amount prior to the Transaction Effective Date shall be held in trust for the benefit of the other Parties and shall be promptly allocated among, and paid over to, the other Parties in accordance with the percentages set forth on Schedule 1, and (b) any payment received by it from time to time from Constellation from the New Deposit Amount as of and after the Transaction Effective Date shall be held in trust for the benefit of the other Parties and shall be promptly allocated among, and paid over to, the other Parties in accordance with the percentages set forth on Schedule 2(b).

8. Termination.  This Agreement will terminate upon the last to occur of the termination of the Certificate Purchase Agreement and the Backup Agreement, the final resolution of any claims thereunder and the expiration of any statute of limitation on any claims that can be made thereunder.

9. Further Assurances.  Each Party agrees that from time to time on and after the date hereof, at the reasonable request of any other Party, it shall promptly execute and deliver all further instruments and

4

documents, and take all further action, that may be necessary or desirable in order to accomplish the purposes of this Agreement.

10. Assignment.  Neither this Agreement, nor any portion, right or obligation hereunder, may be assigned by any Party to any other Party or third party except that any Trust may assign its rights and obligations under this Agreement to a liquidating trust pursuant to a plan of liquidation of such Trust.

11. Amendments.  This Agreement may be amended or modified only by an instrument in writing duly executed by the Parties hereto; provided that an amendment or modification that affects some, but not all, Parties, shall be effective as among the amending or modifying Parties; provided further than no such amendment or modification shall be binding upon a Party that is not a party to such written amendment or modification.

12. Entire Agreement.  This Agreement constitutes the entire agreement among the Parties with respect to its subject.

13. Counterparts; Facsimile Signatures.  Two or more counterparts of this Agreement may be signed by the Parties, each of which shall be an original but all of which together shall constitute one and the same instrument. Facsimile signatures on this Amendment shall have the same force and effect as original signatures.

14. Governing Law.  This Agreement shall be governed by and construed in accordance with the laws of the State of New York without regard to principles of conflicts of law. Each Party waives its respective right to any jury trial with respect to any litigation arising under or in connection with this Agreement.

Exhibit 99

Covanta Announces Acquisition of Two
Biomass Energy Facilities in Maine

Acquisition Adds Renewable Electricity Generation in the
Attractive New England Power Market

FAIRFIELD, NJ, August 25, 2008 — Covanta Holding Corporation (NYSE: CVA), a world leader in development, operation and ownership of Energy-from-Waste and renewable energy facilities, today announced that it has entered into an agreement to purchase two biomass energy facilities from co-owners Ridgewood Maine, L.L.C. and Indeck Energy Services, Inc.

The two nearly identical facilities, located in West Enfield and Jonesboro Maine, will add a total of 49 gross megawatts to Covanta’s renewable energy portfolio, which currently includes six biomass facilities and 38 Energy-from-Waste facilities. The acquisition will represent a 35% increase in gross electrical capacity from our biomass facilities. We intend to sell the electric output and renewable energy credits from these new facilities into the attractive New England market.

Covanta has agreed to acquire these two facilities for approximately $87 million net of cash acquired. The transaction will be funded from cash on hand and/or by drawing upon our existing revolving loan facility.

Closing of the acquisition remains subject to receipt of certain regulatory approvals as well as approval by Ridgewood’s shareholders. These conditions are anticipated to be met by year’s end.

“We are very excited about acquiring these two biomass facilities to expand our renewable energy portfolio,” said Anthony Orlando, President and Chief Executive Officer of Covanta. “Our operating expertise and existing infrastructure will enable us to maximize their value. Furthermore, we see strategic benefits by expanding our presence in New England, which enjoys strong demand and regulatory incentives for renewable electricity.”

Biomass energy facilities, also referred to as wood waste facilities, combust biomass to produce renewable electricity. Biomass may include: woodchips, sawdust, bark, tree trimmings, agricultural waste and wood recovered from construction demolition activities.

About Covanta

communities with an environmentally sound solution to their solid waste disposal needs by using that municipal solid waste to generate clean, renewable energy. Annually, Covanta’s modern Energy-from-Waste facilities safely and securely convert more than16 million tons of waste into more than 8 million megawatt hours of clean renewable electricity and create 10 billion pounds of steam that are sold to a variety of industries.

Ridgewood Trusts—Additional Information and Where to Find It
Ridgewood Electric Power Trust IV and Ridgewood Electric Power Trust V are the indirect owners of the two biomass facilities. It is Covanta’s understanding that the Trust(s) plan to file with the SEC and mail to its shareholders a proxy statement to be used by the Trust(s) to solicit the approval of its shareholders for the transaction. Ridgewood Renewable Power, LLC. urges that shareholders of the Trust(s) read the proxy statement, when it becomes available, and any other relevant documents filed by the Trust(s) with the SEC, because they will contain important information about the transaction. When available, shareholders of the Trust(s) can obtain free copies of any such materials (including the proxy statement) filed by the Trust(s) with the SEC, as well as other filings containing information about the Trust(s) at the SEC’s Internet Site (http://www.sec.gov).

The Trusts and their executive officers and directors may be deemed, under SEC rules, to be participants in the solicitation of proxies or consents from the Trusts’ shareholders with respect to the sale of assets of the Trusts’ biomass operations. As required by SEC rules, the proxy statement relating to the transaction that will be filed with the SEC by the Trusts will contain information regarding the executive officers and directors of the Trusts, including their direct or indirect interests in the transaction.
