          (i) all rights of Pledgor to terminate, amend, supplement, modify, or cancel, the Governing Documents of SWMP, to take all actions thereunder and to compel performance and otherwise exercise all remedies thereunder;

          (j) all securities, notes, certificates and other instruments representing or evidencing any of the foregoing rights and interests or the ownership thereof and any interest of Pledgor reflected in the books of any financial intermediary pertaining to such rights and interests and all non-cash dividends, cash, options, warrants, stock splits, reclassifications, rights, instruments or other investment property and other property or proceeds from time to time received, receivable or otherwise distributed in respect of or in exchange for any or all of such rights and interests; and

          (k) to the extent not included in any of the foregoing, all proceeds of the foregoing Collateral, whether cash or non-cash;

provided, however, that “Collateral” shall not include (i) any distribution, repayment of subordinated debt or any other payments made by or on behalf of SWMP to Pledgor expressly permitted pursuant to the terms of the Credit Documents, (ii) any amounts in the Deposit Account (as defined in the Purchase Agreement) or any of Pledgor’s rights under the Security Agreement or the Deposit Account Control Agreement (each as defined in the Purchase Agreement), (iii) any rights of or any amounts payable to Pledgor under Section 2.02, 2.05 or 12.03 of the Purchase Agreement, and (iv) any rights of, any amounts payable or any allocations to Pledgor under Article 5, Sections 7.5, 7.6 7.7 and 8.10 of the LLC Agreement and Article 11 of the Purchase Agreement, solely to the extent any such rights, amounts or allocations of such clause (iv) relate to acts, omissions, allocations or matters arising prior to the time that Pledgor is divested of ownership of the Class A Interest pursuant to this Agreement.

ARTICLE III.
OBLIGATIONS SECURED

     Without limiting the generality of the foregoing, this Agreement and all of the Collateral secure the payment and performance when due of all Obligations. If enforcement of the liability of Pledgor under this Agreement (not to exceed the value of the Collateral) would be an unlawful or voidable transfer under any applicable fraudulent transfer law or any comparable law, notwithstanding the representation and warranty set forth in Section 4.13 or anything to the contrary herein, then the liability of Pledgor hereunder shall be reduced to the greater of (a) the highest amount for which such liability may then be enforced without giving rise to an unlawful or voidable transfer under any such law and (b) the value of the Collateral.

ARTICLE IV.
REPRESENTATIONS AND WARRANTIES OF PLEDGOR

     Pledgor represents and warrants to and in favor of Collateral Agent, as of the date hereof, as follows:

     4.1 Organization. Pledgor is (a) a limited liability company duly organized, validly existing and in good standing under the laws of the State of Delaware, (b) duly qualified as a foreign limited liability company and in good standing, in each jurisdiction in which such qualification is required by law, and (c) duly qualified, authorized to do business and in good standing in each jurisdiction in which such qualification is necessary to execute, deliver and perform this Agreement and each of the other Project Documents to which it is a party.

     4.2 Power and Authorization; Enforceable Obligations. Pledgor has the full limited liability company power and authority to execute, deliver and perform this Agreement and to take all action as may be necessary to complete the transactions contemplated hereunder. Pledgor has taken all necessary limited liability company action to authorize the execution, delivery and performance of this Agreement and to complete the transactions contemplated hereby. No consent or authorization of, filing with, or other act by or in respect of any other Person or governmental authority is required in connection with the execution, delivery or performance by Pledgor, or the validity or enforceability as to Pledgor, of this Agreement, except such consents or authorizations or filings or other acts as have already been obtained or made. This Agreement has been duly executed and delivered by Pledgor and constitutes a legal, valid and binding obligation of Pledgor enforceable against it in accordance with its terms, except as enforceability may be limited by applicable bankruptcy, insolvency, reorganization, moratorium or similar laws affecting the right of creditors generally and by general principles of equity.

     4.3 No Legal Bar. The execution, delivery and performance by Pledgor of this Agreement and the consummation of the transactions contemplated hereby (including the granting of security interests hereunder) do or will not violate any applicable law or any material contractual obligation of Pledgor and do or will not result in, or require, the creation or imposition of any Lien (other than the Liens created pursuant to this Agreement) on any of the properties or revenues of Pledgor pursuant to any applicable law or any such contractual obligation.

     4.4 Beneficial Ownership; Pledged Equity Interests. Pledgor is the lawful and beneficial owner of and has full right, title and interest in, to and under rights and interests comprising the Collateral, subject to no Liens (other than the Lien in favor of the Collateral Agent (on behalf of the Secured Parties)). The Pledged Equity Interests (a) have been duly authorized and validly issued, (b) are fully paid and non-assessable and (c), together with the Class B Interest (as defined in the LLC Agreement) held by Renegy Holdings and pledged to Collateral Agent pursuant to the Renegy Pledge Agreement, constitute all of the outstanding membership interests of SWMP. The Pledged Equity Interests are not securities governed by Article 8 of the New York Uniform Commercial Code, and are not certificated.

     4.5 No Prior Assignment. Pledgor has not previously assigned any of its rights in, to or under all or any portion of the Collateral.

     4.6 No Other Financing Documents. Pledgor has not executed and is not aware of any effective financing statement, security agreement or other instrument similar in effect covering all or any part of the Collateral on file in any recording office, except such as may have been filed pursuant to this Agreement and the other Credit Documents.

     4.7 Compliance with Law. Pledgor is in compliance with all applicable laws, except noncompliance which could not reasonably be expected to have a Material Adverse Effect, and no written notices of any material violation of any law relating to the Project or any Project Document have been received by Pledgor.

     4.8 No Litigation. There are no pending or, to Pledgor’s knowledge, threatened in writing actions, suits, proceedings or investigations of any kind, including actions or proceedings of or before any governmental authority, relating to the Collateral or to which Pledgor is a party or is subject, or by which it or its properties are bound that, if adversely determined to or against Pledgor could reasonably be expected to have a Material Adverse Effect.

     4.9 Taxes. Pledgor has timely filed all federal, state and local tax returns that it is required to file (except where a failure to file such local tax return could not reasonably be expected to have a Material Adverse Effect), has paid all taxes it is required to pay to the extent due (other than those taxes that it is contesting in good faith and by appropriate proceedings, with adequate reserves established for such taxes) and, to the extent such taxes are not due, has established reserves that are adequate for the payment thereof to the extent required by GAAP.

     4.10 Investment Company Act; Federal Energy Laws. Pledgor is not an “investment company” or a company “controlled” by an “investment company,” within the meaning of the Investment Company Act of 1940, as amended. No provision of the Federal Power Act or the Public Utility Holding Company Act as to securities, rates or financial or organizational matters precludes Pledgor from entering into and performing its obligations hereunder.

     4.11 Name; Organizational Number. The name of Pledgor is “AZ Biomass LLC”, as indicated in the public records of the State of Delaware, and Pledgor’s federal employee identification number is ###-###-#### and Pledgor’s Delaware organizational number is 08110528.

     4.12 SWMP Information. Pledgor has established adequate means of obtaining financial and other information pertaining to the businesses, operations and condition (financial or otherwise) of SWMP and its properties on a continuing basis, and Pledgor now is and hereafter will be completely familiar with the businesses, operations and condition (financial or otherwise) of SWMP and its properties. Pledgor hereby agrees that Collateral Agent shall not have any duty to advise Pledgor of information known to Collateral Agent regarding such condition or any such circumstances or of any changes or potential changes affecting the Collateral. In the event Collateral Agent, in its respective discretion, undertakes at any time or from time to time to provide any such information to Pledgor, Collateral Agent shall not be under any obligation (a) to undertake any investigation not a part of its regular business routine, or reasonable commercial lending practices or (b) to make any other or future disclosure of such information to Pledgor.

     4.13 Capital Adequacy, Etc.

          (a) After giving effect to the transactions contemplated by this Agreement and the contingent obligations evidenced hereby, Pledgor is not, on either an unconsolidated basis or a consolidated basis with any Person that directly or indirectly controls Pledgor, insolvent as such term is used or defined in any applicable Bankruptcy Law, and Pledgor has and will have assets which, fairly valued, exceed its indebtedness, liabilities or obligations.

          (b) Pledgor is not executing this Agreement with any intention to hinder, delay or defraud any present or future creditor or creditors of Pledgor.

          (c) Pledgor is not engaged in any business or transaction which, after giving effect to the transactions contemplated by this Agreement, will leave Pledgor with capital or assets which are unreasonably small in relation to the business or transactions engaged by Pledgor, and Pledgor does not intend to engage in any such business or transaction.

          (d) Pledgor does not intend to incur, nor does Pledgor believe that it will incur, debts beyond Pledgor’s ability to repay such debts as they mature.

     4.14 Perfection of Security Interest. The security interest granted to Collateral Agent pursuant to this Agreement constitutes as to personal property included in the Collateral a valid lien. The security interest granted to Collateral Agent pursuant to this Agreement in the Collateral consisting of personal property will be perfected (a) with respect to any property that can be perfected by filing, upon the filing of financing statements in the proper filing offices and (b) with respect to any property, if any, that can be perfected by possession, upon Collateral Agent receiving possession thereof and, in each case, such security interest will be, as to Collateral perfected under the UCC or otherwise as aforesaid, superior and prior to the rights of all third Persons now existing or hereafter arising whether by way of mortgage, lien, security interests, encumbrance, assignment or otherwise.

     4.15 After-Acquired Collateral. It is understood and agreed that the foregoing representations and warranties shall apply only to the Collateral pledged on the date hereof and that, with respect to Collateral pledged thereafter, Pledgor shall, upon the written request of Collateral Agent, be required to make representations and warranties in form and substance

substantially similar to the foregoing in supplements hereto and that such representations and warranties contained in such supplements hereto shall be applicable to such Collateral hereafter delivered.

ARTICLE V.
COVENANTS OF PLEDGOR

     Pledgor covenants to and in favor of Collateral Agent as follows:

     5.1 Compliance with Obligations. Pledgor shall perform and comply in all material respects with all obligations and conditions on its part to be performed with respect to the Collateral.

     5.2 Defense of Collateral. Pledgor shall, until the payment in full in cash and performance in full of all Obligations and the termination of all the Lender’s Commitments and all other obligations to the Secured Parties under the Credit Documents (other than the Obligations that are intended to survive the termination of the Credit Documents and return or expiration of the Letter of Credit), defend its title to the Collateral and the interest of Collateral Agent in the Collateral pledged hereunder against the claims and demands of all Persons.

     5.3 Preservation of Value; Limitation of Liens. Pledgor shall not take or permit to be taken any action in connection with the Collateral which would impair in any material respect the value of the interests or rights of Pledgor therein or which would impair the interests or rights of Collateral Agent therein or with respect thereto, except as expressly permitted by the Credit Documents or the Forbearance Agreement; provided, however, that nothing in this Agreement shall prevent Pledgor, prior to the exercise by Collateral Agent of any rights pursuant to the terms hereof, from undertaking Pledgor’s operations in the ordinary course of business in accordance with the Credit Documents. Pledgor shall not directly or indirectly create, incur, assume or suffer to exist any Liens on or with respect to all or any part of the Collateral (other than the Liens in favor of the Collateral Agent (on behalf of the Secured Parties)). Pledgor shall at its own cost and expense promptly take such action as may be necessary to discharge any such Liens.

     5.4 No Other Filings. Pledgor shall not file or authorize or permit to be filed in any jurisdiction any financing statements under the UCC or any like statement relating to the Collateral in which Collateral Agent is not named as the sole secured party.

     5.5 No Sale of Collateral. Pledgor shall not cause, suffer or permit the sale, assignment, conveyance, pledge or other transfer of all or any portion of Pledgor’s ownership or interest or any portion of the Collateral, except as provided in Sections 2.05, 12.03 or 13.09 of the Purchase Agreement, or Article X of the LLC Agreement, provided that any such transferee assumes Pledgor’s rights and obligations hereunder, under the Forbearance Agreement, the LLC Agreement and the Purchase Agreement and executes such other documents as reasonably requested by Collateral Agent to continue its first priority lien on the Collateral. Upon such assignment and assumption, Pledgor shall have no liability or obligations under this Agreement with respect to matters arising after the date of such assignment and assumption. As used herein, the transfer of an ownership interest in the Collateral shall not include the direct or indirect sale,

assignment, pledge, hypothecation, transfer or other disposition (voluntarily or involuntarily, by gift or otherwise, and whether as security or otherwise) of any equity interest in Pledgor or in any Person that controls Pledgor.

     5.6 Notice. Pledgor shall promptly, upon acquiring notice or giving notice, as the case may be, or obtaining knowledge thereof, give written notice (with copies of any such underlying notices) to Collateral Agent of any and all writings, documents or instruments evidencing any additional Collateral or any Collateral which has been converted from one type of Collateral into another type, including, without limitation, any Collateral with respect to which possession is required or permitted for the Lien and security interest granted therein under this Agreement to be perfected.

     5.7 Filing of Bankruptcy Proceedings. To the extent it may so agree to do so under applicable law, Pledgor, for itself, its successors and assigns, shall not cast any vote as an owner in SWMP (a) in favor of the commencement of a voluntary case or other proceeding seeking liquidation, reorganization, rehabilitation or other relief with respect to SWMP or its debts under any bankruptcy, insolvency or other similar law now or hereafter in effect in any jurisdiction or seeking the appointment of a trustee, receiver, liquidator, custodian or other similar official of the owners of SWMP or any substantial part of SWMP’s property, (b) to authorize SWMP to consent to any such aforesaid relief or to the appointment of or taking possession by any such aforesaid official in an involuntary case or other proceeding commenced against SWMP or (c) to authorize SWMP to make a general assignment for the benefit of creditors.

     5.8 Distributions. If Pledgor in its capacity as owner of SWMP receives any income, dividend or other distribution of money or property of any kind from SWMP (other than as expressly permitted by the Credit Documents), Pledgor shall hold such income or distribution as trustee for, and shall promptly deliver the same to, Collateral Agent.

     5.9 Maintenance of Records. Pledgor shall, at all times, keep accurate and complete records of the Collateral. Pledgor shall permit representatives of Collateral Agent, upon reasonable prior written notice, at any time during normal business hours of Pledgor to inspect and make abstracts from Pledgor’s books and records pertaining to the Collateral. Upon the occurrence and during the continuation of any Event of Default, at Collateral Agent’s written request, Pledgor shall promptly deliver copies of any and all such records to Collateral Agent.

     5.10 Name; Jurisdiction of Organization. Pledgor shall not change its name, its jurisdiction of organization, the location of its principal place of business, its organization identification number or its fiscal year without notice to Collateral Agent at least 30 days prior to such change. In the event of such change, Pledgor shall at its expense or at the expense of SWMP, as applicable execute and deliver such instruments and documents as may be reasonably required by Collateral Agent or applicable law to maintain a prior perfected security interest in the Collateral.

     5.11 Amendments to Organizational Documents. Except as expressly permitted by this Agreement or the other Credit Documents, Pledgor shall not terminate, amend, supplement or otherwise modify, or cancel, the Governing Documents of SWMP without the prior written consent of Collateral Agent.

     5.12 Proceeds of Collateral. Pledgor shall, at all times, keep pledged to Collateral Agent pursuant hereto all Collateral and shall not consent to the issuance by SWMP of any membership interests or other equity interests unless such membership interests or other equity interests are immediately duly pledged to Collateral Agent hereunder on a first priority perfected basis.

     5.13 Collateral Secured by Possession. Pledgor shall, if requested by Collateral Agent, properly deliver or cause to be delivered to Collateral Agent all Collateral in which the Lien and security interest granted therein under this Agreement may be or is required to be perfected by possession.

ARTICLE VI.
EVENTS OF DEFAULT

          (h) take any other action which Collateral Agent deems necessary or desirable to protect or realize upon its security interest in the Collateral or any part thereof, and Pledgor hereby irrevocably appoints Collateral Agent as Pledgor’s attorney-in-fact (as set forth in Section 8.3) to take any such action, including the execution and delivery of any and all documents or instruments related to the Collateral or any part thereof in Pledgor’s name, and said appointment shall create in Collateral Agent a power coupled with an interest which shall be irrevocable; or

          (i) appoint another Person (who may be an employee, officer or other representative of Collateral Agent) to do any of the foregoing, or take any other action permitted hereunder, as agent for or representative of, and on behalf of, Collateral Agent.

     7.2 Minimum Notice Period. If, pursuant to applicable law, prior notice of any action described in Section 7.1 is required to be given to Pledgor or SWMP, Pledgor and SWMP hereby acknowledge and agree that the minimum time required by such applicable law, or if no minimum is specified, 10 Business Days, shall be deemed a reasonable notice period.

     7.3 Right to Cure. In addition to the foregoing remedies, Collateral Agent may, but shall not be obligated to, cure any Event of Default and incur reasonable fees, costs and expenses in doing so, in which event SWMP shall reimburse Collateral Agent within five Business Days after written demand for all such fees, costs and expenses, together with interest thereon at the Default Rate from the date payable until the date repaid in full.

     7.4 Expenses; Interest. All reasonable costs and expenses (including reasonable attorneys’ fees and expenses) incurred by Collateral Agent in connection with exercising any actions taken under Section 7.1, together with interest thereon (to the extent permitted by law) computed at a rate per annum equal to the Default Rate or the maximum rate permitted by law, whichever is less, from the date due to the date of payment thereof, shall be added to the indebtedness secured by this Agreement and shall be paid by SWMP to Collateral Agent within 10 Business Days after written demand.

     7.5 Sale of Collateral. In addition to exercising the foregoing rights, upon the occurrence and during the continuation of an Event of Default, Collateral Agent may, subject to the terms and conditions of the Forbearance Agreement and to the extent permitted by applicable law, arrange for and conduct a sale of the Collateral at a public or private sale (as Collateral Agent may elect) which sale may be conducted by an employee or representative of Collateral Agent, without any demand of performance or notice of intention to sell or dispose of, or of time or place of sale or disposition (except such notice as required by any applicable law), and any such sale shall be considered or deemed to be a sale made in a commercially reasonable manner. Collateral Agent may release, temporarily or otherwise, to Pledgor any item of Collateral of which Collateral Agent has taken possession pursuant to any right granted to Collateral Agent by this Agreement without waiving any rights granted to Collateral Agent under this Agreement, the

Credit Agreement or the other Credit Documents. Pledgor, in dealing with or disposing of the Collateral or any part thereof, hereby waives all rights, legal and equitable, it may now or hereafter have to require marshaling of assets or to require, upon foreclosure, sales of assets in a particular order. Pledgor also waives its right to challenge the reasonableness of any disclaimer of warranties, title and the like made by Collateral Agent in connection with a sale of the Collateral. Each successor and assign of Pledgor, including a holder of a Lien subordinate to the Lien created hereby (without implying that Pledgor has, except as expressly provided in the Credit Documents, a right to grant an interest in, or a subordinate Lien on, any of the Collateral), by acceptance of its interest or Lien agrees that it shall be bound by the above waiver, to the same extent as if such holder gave the waiver itself. Pledgor also hereby waives, to the full extent it may lawfully do so, the benefit of all laws providing for rights of appraisal, valuation, stay or extension or of redemption after foreclosure now or hereafter in force. If Collateral Agent sells any of the Collateral upon credit, Pledgor will be credited only with payments actually made by the purchaser, received by Collateral Agent and applied to the indebtedness of the purchaser. In the event the purchaser fails to pay for the Collateral, Collateral Agent may resell the Collateral and Pledgor shall be credited with the proceeds of the sale. In the event Collateral Agent shall bid at any foreclosure or trustee’s sale or at any private sale permitted by law or this Agreement or any other Credit Document, Collateral Agent may bid all or less than the amount of the Obligations. To the extent permitted by applicable law, the amount of the successful bid at any such sale, whether Collateral Agent or any other party is the successful bidder, shall be conclusively deemed to be the fair market value of the Collateral and the difference between such bid amount and the remaining balance of the Obligations shall be conclusively deemed to be the amount of the Obligations.

     7.6 Compliance With Limitations and Restrictions. Pledgor hereby agrees that in respect of any sale of any of the Collateral pursuant to the terms hereof, Collateral Agent is hereby authorized to comply with any limitation or restriction in connection with such sale as Collateral Agent may be advised by counsel is necessary in order to avoid any violation of applicable law, or in order to obtain any required approval of the sale or of the purchaser by any governmental authority or official, and Pledgor further agrees that such compliance shall not, in and of itself, result in such sale being considered or deemed not to have been made in a commercially reasonable manner, nor shall Collateral Agent be liable or accountable to Pledgor for any discount allowed by reason of the fact that such Collateral is sold in compliance with any such limitation or restriction.

     7.7 No Impairment of Remedies. If, in the exercise of any of its rights and remedies under this Agreement, Collateral Agent shall forfeit any of its rights or remedies, whether because of any applicable law pertaining to “election of remedies” or otherwise, Pledgor hereby consents to such action by Collateral Agent and, to the extent permitted by applicable law, waives any claim based upon such action, even if such action by Collateral Agent shall result in a full or partial loss of any rights of subrogation, indemnification or reimbursement which Pledgor might otherwise have had but for such action by Collateral Agent or the terms herein. Any election of remedies which results in the denial or impairment of the right of Collateral Agent to seek a deficiency judgment against SWMP shall not, to the extent permitted by applicable law, impair Pledgor’s obligations hereunder.

     7.8 Foreclosure upon Class B Interests. Notwithstanding anything in the LLC Agreement to the contrary, Pledgor hereby consents to any exercise by Collateral Agent of its rights and remedies granted under the Renegy Pledge Agreement, including foreclosure upon the Class B Interest (as defined in the LLC Agreement), and shall provide Collateral Agent with any instruments, certificates or other documents reasonably requested by Collateral Agent in order to evidence such foreclosure. Pledgor hereby acknowledges that, upon such foreclosure, neither the Collateral Agent nor the transferee of the Class B Interest shall be bound by the obligations of the Class B Member or Sponsor (each as defined in the LLC Agreement) under Sections 3.4 or 4.4 of the LLC Agreement (provided that Sponsor shall continue to be bound by such provisions according to their terms) and, with respect to any transfer by the Collateral Agent up to and including transfer to the ultimate purchaser not affiliated with any Lender, Article X thereunder.

ARTICLE VIII.
MISCELLANEOUS

     8.1 Remedies Cumulative; Delay Not Waiver.

          8.1.1 Remedies Cumulative. No right, power or remedy herein conferred upon or reserved to Collateral Agent is intended to be exclusive of any other right, power or remedy, and every such right, power and remedy shall, to the extent permitted by applicable law, be cumulative and in addition to every other right, power and remedy given hereunder or now or hereafter existing at law or in equity or otherwise. The assertion or employment of any right or remedy hereunder shall not prevent the concurrent assertion or employment of any other appropriate right or remedy. Resort to any or all security now or hereafter held by Collateral Agent may be taken concurrently or successively and in one or several consolidated or independent judicial actions or lawfully taken nonjudicial proceedings, or both. If Collateral Agent may, under applicable law and in accordance with the terms and conditions of the Forbearance Agreement, proceed to realize its benefits under this Agreement or any other Credit Document giving Collateral Agent a Lien upon any Collateral, whether owned by Pledgor or by any other Person, either by judicial foreclosure or by non-judicial sale or enforcement, Collateral Agent may, at its sole option, determine which of its remedies or rights it may pursue without affecting any of the rights and remedies of Collateral Agent under this Agreement.

          8.1.2 No Waiver; Separate Causes of Action. No delay or omission to exercise any right, power or remedy accruing to Collateral Agent upon the occurrence and during the continuance of any Event of Default as aforesaid shall impair any such right, power or remedy of Collateral Agent, nor shall it be construed to be a waiver of any such Event of Default or of any similar breach or default thereafter occurring or an acquiescence therein, nor shall any waiver of any other breach or default under this Agreement or any other Credit Document be deemed a waiver of any other breach or default theretofore or thereafter occurring. Each and every default by Pledgor in payment hereunder shall give rise to a separate cause of action hereunder, and separate suits may be brought hereunder as each cause of action arises and every power and remedy given by this Agreement may be exercised from time to time, and as often as shall be deemed expedient, by Collateral Agent.

          8.1.3 Application of Proceeds. The proceeds of any sale of or other realization upon, all or any part of the Collateral taken in accordance with this Agreement, shall be applied

to the repayment of the Loans and otherwise in accordance with the Credit Agreement. The Borrowers shall remain liable for any deficiency.

          8.1.4 Certain Waivers. Pledgor hereby waives and relinquishes, to the maximum extent permitted by applicable law, all rights and remedies accorded to pledgors, sureties or guarantors and agrees not to assert or take advantage of any such rights or remedies, including:

               (a) any law limiting remedies, including recovery of a deficiency against the Borrowers, under an obligation secured by a mortgage or deed of trust on real property if the real property is sold under a power of sale contained in the mortgage or deed of trust, and all defenses based on any loss whether as a result of any such sale or otherwise;

               (b) any right to require Collateral Agent to proceed against the Borrowers or any other Person or to proceed against or exhaust any security held by Collateral Agent at any time or to pursue any other remedy in Collateral Agent’s power before proceeding against the Collateral;

               (c) any defense that may arise by reason of the incapacity, lack of power or authority, death, dissolution, merger, termination or disability of Pledgor, any Borrower or any other Person or the failure of Collateral Agent or any Secured Party to file or enforce a claim against the estate (in administration, bankruptcy or any other proceeding) of Pledgor, any Borrower or any other Person;

               (d) any right to enforce any remedy that Collateral Agent may have against any Borrower or any other Person and any right to participate in any security held by Collateral Agent until the Obligations have been paid and the covenants of the Credit Documents have been performed in full;

               (e) any right to require Collateral Agent to give any notices of any kind, including, without limitation, notices of nonpayment, nonperformance, protest, dishonor, default, delinquency or acceleration, or to make any presentments, demands or protests, except as set forth herein or expressly provided in the Credit Agreement or any of the Credit Documents;

               (f) any right to assert the bankruptcy or insolvency of the Borrowers or any other Person as a defense hereunder or as the basis for rescission hereof and any defense arising because of Collateral Agent’s election, in any proceeding instituted under the Federal Bankruptcy Code, of the application of Section 1111(b)(2) of the Federal Bankruptcy Code;

               (g) subject to Section 8.9, any right under any law purporting to reduce Pledgor’s obligations hereunder if the Obligations are reduced other than as a result of payment of such Obligations;

               (h) any defense based on the repudiation of the Credit Documents by any Borrower or any other Person, the failure by Collateral Agent or any Secured Party to enforce any claim against Pledgor, any Borrower or any other Person or the unenforceability in whole or in part of any Credit Documents;

               (i) all suretyship and guarantor’s defenses generally;

               (j) any right to insist upon, plead or in any manner whatever claim or take the benefit or advantage of, any appraisal, valuation, stay, extension, marshaling of assets, redemption or similar law, or exemption, whether now or at any time hereafter in force, which may delay, prevent or otherwise affect the performance by Pledgor of its obligations under, or the enforcement by Collateral Agent of, this Agreement;

               (k) any requirement on the part of Collateral Agent to mitigate the damages resulting from any default;

               (l) any defense based upon an election of remedies by Collateral Agent, including an election to proceed by non-judicial rather than judicial foreclosure, which destroys or otherwise impairs the subrogation rights of Pledgor, the right of Pledgor to proceed against any Borrower or another Person for reimbursement, or both;

               (m) any defense based on any offset against any amounts which may be owed by any Person to Pledgor for any reason whatsoever;

               (n) any defense based on any act, failure to act, delay or omission whatsoever on the part of any Borrower or any of their Affiliates or the failure by any Borrower or any of their Affiliates to do any act or thing or to observe or perform any covenant, condition or agreement to be observed or performed by it under the Credit Documents;

               (o) any defense, setoff or counterclaim which may at any time be available to or asserted by any Borrower or any of their Affiliates against Collateral Agent or any Secured Party or any other Person under the Credit Documents;

               (p) any duty on the part of Collateral Agent to disclose to Pledgor any facts Collateral Agent may now or hereafter know about any Borrower or any of their Affiliates, regardless of whether Collateral Agent has reason to believe that any such facts materially increase the risk beyond that which Pledgor intends to assume, or have reason to believe that such facts are unknown to Pledgor, or have a reasonable opportunity to communicate such facts to Pledgor;

               (q) any defense based on any change in the time, manner or place of any payment under, or in any other term of, the Credit Documents or any other amendment, renewal, extension, acceleration, compromise or waiver of or any consent or departure from the terms of the Credit Documents; and

               (r) any defense based upon any borrowing or grant of a security interest under Section 364 of Title 11 of the United States Code.

          8.1.5 Foreclosure Waiver. To the extent permitted by applicable law, Pledgor waives the posting of any bond otherwise required of Collateral Agent in connection with any judicial process or proceeding to obtain possession of, replevy, attach, or levy upon the Collateral, to enforce any judgment or other security for the Obligations, to enforce any judgment or other court order entered in favor of Collateral Agent, or to enforce by specific

performance, temporary restraining order, preliminary or permanent injunction, this Agreement or any other agreement or document between Pledgor and Collateral Agent. Except as provided in the Forbearance Agreement, Pledgor further agrees that upon the occurrence and during the continuation of an Event of Default, Collateral Agent may elect to nonjudicially or judicially foreclose against any real or personal property security it holds for the Obligations or any part thereof, or to exercise any other remedy against any Borrower or any other Person, any security or any guarantor, even if the effect of that action is to deprive Pledgor of the right to collect reimbursement from any Borrower or any other Person for any sums paid by Pledgor to Collateral Agent.

          8.1.6 Waiver of Rights of Subrogation. Until the indefeasible payment in full in cash of the Obligations and the termination of all the Lender’s Commitments and all other obligations to the Secured Parties under the Credit Documents (other than the Obligations that are intended to survive the termination of the Credit Documents), (a) Pledgor shall not have any right of subrogation and waives all rights to enforce any remedy which Collateral Agent now have or may hereafter have against SWMP or any of their Affiliates, and waives the benefit of, and all rights to participate in, any security now or hereafter held by Collateral Agent from any Borrower or any of their Affiliates and (b) Pledgor waives any claim, right or remedy which Pledgor may now have or hereafter acquire against any Borrower or any of their Affiliates that arises hereunder and/or from the performance by Pledgor hereunder, including any claim, remedy or right of subrogation, reimbursement, exoneration, contribution, indemnification, or participation in any claim, right or remedy of Collateral Agent against any Borrower or any of their Affiliates, or any security which Collateral Agent now have or hereafter acquire, whether or not such claim, right or remedy arises in equity, under contract, by statute, under common law or otherwise. Any amount paid to Pledgor on account of any such subrogation rights prior to the payment in full in cash of the Obligations and the termination of the Lender’s Commitments and all other obligations to the Secured Parties under the Credit Documents (other than the Obligations that are intended to survive the termination of the Credit Documents) shall be held in trust for the benefit of the Secured Parties and shall immediately thereafter be paid to Collateral Agent, for the benefit of the Secured Parties.

     8.2 SWMP’s Consent and Covenant. SWMP hereby consents to the assignment of and grant of a security interest in the Collateral to Collateral Agent for the benefit of the Secured Parties and to the exercise by Collateral Agent of all rights and powers assigned or delegated to Collateral Agent by Pledgor hereunder, including the rights upon and during an Event of Default to exercise Pledgor’s voting rights and other rights to manage or control SWMP, all in accordance with the Credit Documents and the Forbearance Agreement.

     8.3 Attorney-in-Fact. Pledgor hereby constitutes and appoints Collateral Agent, acting for and on behalf of itself and each successor or assign of Collateral Agent the true and lawful attorney-in-fact of Pledgor, with full power and authority in the place and stead of Pledgor and in the name of Pledgor, Collateral Agent or otherwise, subject to the terms of the Credit Agreement, this Agreement, the Forbearance Agreement and applicable law, to enforce all rights, interests and remedies of Pledgor with respect to the Collateral, including the right:

          (a) to ask, require, demand, receive and give acquittance for any and all moneys and claims for money due and to become due under or arising out of the Collateral, including any insurance policies;

          (b) to elect remedies under the Collateral and to endorse any checks or other instruments or orders in connection therewith;

          (c) to vote, demand, receive and enforce Pledgor’s rights with respect to the Collateral;

          (d) to give appropriate receipts, releases and satisfactions for and on behalf of and in the name of Pledgor or, at the option of Collateral Agent, in the name of Collateral Agent, with the same force and effect as Pledgor could do if this Agreement had not been made;

          (e) to file any claims or take any action or institute any proceedings in connection therewith which Collateral Agent may reasonably deem to be necessary or advisable; and

          (f) to pay, settle or compromise all bills and claims which may be or become Liens or security interests against any or all of the Collateral, or any part thereof, unless a bond or other security satisfactory to Collateral Agent has been provided;

provided, however, that Collateral Agent shall not exercise any of the aforementioned rights unless an Event of Default has occurred and is continuing, Collateral Agent has not waived its remedies with respect thereto in accordance with the Credit Documents and the exercise of such rights is not restricted by the Forbearance Agreement. This power of attorney is a power coupled with an interest and shall be irrevocable until the termination of this Agreement in accordance with the terms hereof and the other Credit Documents; provided further, however, that nothing in this Agreement shall prevent Pledgor from, prior to the exercise by Collateral Agent of any of the aforementioned rights, undertaking Pledgor’s operations in the ordinary course of business in accordance with the Collateral and the Credit Documents.

     8.4 Perfection; Further Assurances.

          8.4.1 Perfection. Pledgor agrees that from time to time, at the expense of Pledgor, Pledgor shall promptly execute and deliver all further instruments and documents, and take all further action, that may be reasonably necessary, or that Collateral Agent may reasonably request, in order to perfect, to ensure the continued perfection of, and to protect the assignment and security interest granted or intended to be granted hereby or to enable Collateral Agent to exercise and enforce its rights and remedies hereunder with respect to any Collateral. Without limiting the generality of the foregoing, Pledgor shall (a) deliver the Collateral or any part thereof to Collateral Agent, as Collateral Agent may reasonably request in accordance with this Agreement, accompanied by such duly executed instruments of transfer or assignment as Collateral Agent may reasonably request, and (b) authorize, execute and file such financing or continuation statements, or amendments thereto, and such other instruments, endorsements or notices, as may be reasonably necessary or desirable or as Collateral Agent may reasonably request, in order to perfect and preserve the assignments and security interests granted or purported to be granted hereby.

          8.4.2 Filing of Financing and Continuation Statements. Pledgor hereby authorizes the filing of any financing statements or continuation statements, and amendments to financing statements, or any similar document in any jurisdictions and with any filing offices as Collateral Agent may reasonably determine are necessary or advisable to perfect the security interest granted to Collateral Agent, for the benefit of the Secured Parties, herein. Such financing statements may describe the Collateral in the same manner as described herein or may contain an indication or description of the Collateral that describes such property in any other manner as Collateral Agent may reasonably determine is necessary, advisable or prudent to ensure the perfection of the security interest in the Collateral granted to Collateral Agent herein. Copies of any such financing statements shall promptly be delivered to Pledgor.

          8.4.3 Information Concerning Collateral. Pledgor shall, promptly upon receipt of prior written request, provide to Collateral Agent all information and evidence it may reasonably request concerning the Collateral to enable Collateral Agent to enforce the provisions of this Agreement.

     8.5 Payment of Taxes. Pledgor shall pay or cause to be paid, before any fine, penalty, interest or cost attaches thereto, all taxes, assessments and other governmental or non-governmental charges or levies (other than those taxes that it is contesting in good faith and by appropriate proceedings, and in respect of which it has established adequate reserves for such taxes) now or hereafter assessed or levied against the Collateral pledged by it hereunder (or against the Collateral in which Pledgor has granted to Collateral Agent a security interest of first priority) and shall retain copies of, and, upon written request, permit Collateral Agent to examine receipts showing payment of any of the foregoing.

     8.6 Place of Business; Location of Records. Unless Collateral Agent is otherwise notified under Section 5.10, the chief executive office of Pledgor is, and all records of Pledgor concerning the Collateral are and will be, located at the address set forth in Section 8.12.

     8.7 Continuing Assignment and Security Interest; Transfer of Notes. This Agreement shall create a continuing pledge and assignment of and security interest in the Collateral and shall (a) remain in full force and effect until the payment in full in cash and performance in full of the Obligations (other than the Obligations that are intended to survive the termination of the Credit Agreement) and as otherwise provided in Section 8.9; (b) be binding upon SWMP, Pledgor, and their respective successors and assigns; and (c) inure, together with the rights and remedies of Collateral Agent, to the benefit of the Secured Parties and their successors, transferees and assigns. Without limiting the generality of the foregoing clause (c), Collateral Agent may assign or otherwise transfer the Notes or other evidence of indebtedness held by it for the benefit of the Secured Parties to any other Person to the extent permitted by and in accordance with the Credit Agreement, and such other Person shall thereupon become vested with all or an appropriate part of the benefits in respect thereof granted to Collateral Agent herein or otherwise. The release of the security interest in any or all of the Collateral, the taking or acceptance of additional security, or the resort by Collateral Agent to any security it may have in any order it may deem appropriate, shall not affect the liability of any Person on the indebtedness secured hereby.

     8.8 Termination.

          (a) Upon the payment in full in cash of all Obligations and the termination of all the Lender’s Commitments (other than the obligations that are intended to survive the termination of the Credit Documents and return or expiration of the Letter of Credit), this Agreement and the security interest and all other rights granted hereby shall terminate and all rights to the Collateral shall revert to Pledgor. Upon any such termination, Collateral Agent will return all certificates previously delivered, if any, to Collateral Agent representing the Pledged Equity Interests and, at Pledgor’s expense and upon its written direction, execute and deliver to Pledgor such documents (including UCC-3 termination statements) as any Borrower or Pledgor shall reasonably request to evidence such termination, to release all security interest on the Collateral and to return such Collateral to Pledgor.

          (b) Upon exercise by the Class A Equity Investor of its rescission right in accordance with Section 12.03 of the Purchase Agreement and the assignment by the Class A Equity Investor of the Collateral to Renegy Holdings, this Agreement shall be deemed terminated and the first priority security interest of the Collateral Agent (on behalf of the Secured Parties) shall continue pursuant to the terms and conditions of the Renegy Pledge Agreement. Upon such termination and provided the Collateral Agent maintains such first priority security interest in the Collateral pursuant to the Renegy Pledge Agreement, at Pledgor’s expense and upon its written direction, Collateral Agent shall execute and deliver to Pledgor such documents (including UCC-3 termination statements) as Pledgor shall reasonably request to evidence such termination.

     If this Agreement shall be terminated or revoked by operation of law, Pledgor shall indemnify and save Collateral Agent harmless from any loss (other than any loss arising out of the gross negligence or willful misconduct of Collateral Agent) which may be suffered or incurred by Collateral Agent in acting hereunder prior to the receipt by Collateral Agent, its successors, transferees, or assigns of notice of such termination or revocation.

     8.9 Security Interest Absolute. All rights of Collateral Agent and the security interest hereunder, and all obligations of Pledgor hereunder, shall be unconditional irrespective of: (a) any lack of validity or enforceability of the Credit Agreement, any other Credit Document or any other agreement or instrument relating thereto; (b) the failure of Collateral Agent (i) to assert any claim or demand or to enforce any right or remedy against any Borrower, any Affiliate of any Borrower or any other Person under the provisions of any Credit Document or otherwise or (ii) to exercise any right or remedy against any other guarantor of, or collateral securing, any of the Obligations; (c) any change in the time, manner or place of payment of, or in any other term of the Obligations (including any increase in the amount thereof), or any other amendment or waiver of or any consent to any departure from the any Credit Document; (d) any reduction, limitation, impairment or termination of any of the Obligations for any reason other than the written agreement of the Secured Parties to terminate the Obligations in full, but including any claim of waiver, release, surrender, alteration or compromise, and shall not be subject to, and Pledgor hereby waives any right to or claim of, any defense or setoff, counterclaim, recoupment, or termination whatsoever by reason of the invalidity, illegality, nongenuineness, irregularity, compromise, unenforceability of, or any other event or occurrence affecting, any Secured Obligation of any Borrower, any Affiliate of any Borrower or otherwise; (e) any amendment to, rescission, waiver, or other modification of, or any consent to departure from, any of the terms of any Credit Document; (f) any exchange, surrender, release or non-perfection of any Collateral, or

any release, amendment or waiver or addition of or consent to departure from any other security interest held by Collateral Agent; (g) any bankruptcy or insolvency of any Borrower, Pledgor or any other Person; or (h) any other circumstance which might otherwise constitute a defense available to, or a discharge of, Pledgor or any third party pledgor (other than the defense of payment).

     8.10 Limitation on Duty of Collateral Agent with Respect to the Collateral. The powers conferred on Collateral Agent hereunder are solely to protect its interest in the Collateral for the benefit of the Secured Parties and shall not impose any duty on Collateral Agent or any of its designated agents to exercise any such powers. Except for the safe custody of any Collateral in its possession and the accounting for monies actually received by it hereunder, and except to the extent of any duties imposed by applicable law which have not been waived hereunder, Collateral Agent shall have no duty with respect to any Collateral and no provision of this Agreement shall be interpreted as giving rise to any implied duties or obligations on the part of Collateral Agent. Collateral Agent shall be deemed to have exercised reasonable care in the custody and preservation of the Collateral in its possession if the Collateral is accorded treatment that is substantially equivalent to that which Collateral Agent accords its own property, it being expressly agreed, to the maximum extent permitted by applicable law, that Collateral Agent shall have no responsibility for (a) taking any necessary steps to preserve rights against any Persons with respect to any Collateral, or (b) taking any action to protect against any diminution in value of the Collateral, but, in each case, Collateral Agent may do so and all expenses reasonably incurred in connection therewith shall be part of the Obligations.

     8.11 Amendments; Waivers; Consents. This Agreement may not be amended, amended and restated, supplemented or otherwise modified, except in a writing signed by each of the parties hereto and otherwise in accordance with the provisions of Section 11.21 of the Credit Agreement.

All notices required or permitted under the terms and provisions hereof shall be in writing, and any such notice shall become effective upon delivery in accordance with Section 11.1 of the Credit Agreement.

     8.13 Modification of Obligations. If Collateral Agent shall at any time or from time to time, with or without the consent of, or notice to, Pledgor:

          (a) change or extend the manner, place or terms of payment of, or renew or alter all or any portion of, the Obligations;

          (b) take any action under or in respect of the Credit Documents in the exercise of any remedy, power or privilege contained therein or available at law, equity or otherwise, or waive or refrain from exercising any such remedies, power or privileges;

          (c) amend or modify, in any manner whatsoever, the Credit Documents;

          (d) extend or waive the time for Pledgor’s, any Borrower’s or any other Person’s performance of, or compliance with, any term, covenant or agreement on its part to be performed or observed under the Credit Documents, or waive such performance or compliance or consent to a failure of, or departure from, such performance or compliance;

          (e) take and hold security or collateral for the payment of the Obligations, or sell, exchange, release, dispose of, or otherwise deal with, any property pledged, mortgaged or conveyed, or in which Collateral Agent has been granted a Lien, to secure any indebtedness of Pledgor, any Borrower or any other Person party to a Credit Document to the Secured Parties;

          (f) release or limit the liability of anyone who may be liable in any manner for the payment of any amounts owed by Pledgor, any Borrower or any other Person party to a Credit Document to Collateral Agent;

          (g) modify or terminate the terms of any intercreditor or subordination agreement pursuant to which claims of other creditors of Pledgor, any Borrower or any other Person party to a Credit Document are subordinated to the claims of Collateral Agent; or

          (h) apply any sums by whomever paid or however realized to any amounts owing by Pledgor or any Borrower to the Secured Parties in such manner as Collateral Agent shall determine in its discretion;

then, subject to Section 8.8, Collateral Agent shall not incur any liability to Pledgor pursuant hereto as a result thereof and no such action shall impair or release the obligations of Pledgor under this Agreement.

     8.14 Governing Law. This Agreement, including all matters of construction, validity, performance and the creation, validity, enforcement or priority of the Lien of, and security interests created by, this Agreement in or upon the Collateral shall be governed by the laws of the State of New York, without reference to conflicts of law (other than Section 5-1401 and Section 5-1402 of the New York General Obligations Law), except as required by mandatory provisions of law and except to the extent that the validity or perfection or priority of the Lien and security interest hereunder, or remedies hereunder, in respect of any particular Collateral are governed by the laws of a jurisdiction other than the State of New York.
