          (d) all certificates, instruments or other documents from time to time evidencing any of the foregoing, and all interest, earnings and other proceeds of any of the foregoing.

          The Pledgor agrees that this Agreement, the security interest granted pursuant to this Agreement and all rights, remedies, powers and privileges provided to the Collateral Agent under this Agreement are in addition to and not in any way affected or limited by any other security now or at any time held by the Collateral Agent to secure payment and performance of the Secured Obligations.

          SECTION 3. Security for Secured Obligations. The Collateral secures the prompt and complete payment and performance of all the Secured Obligations.

          SECTION 4. Representations and Warranties. The Pledgor represents and warrants to the Collateral Agent (on behalf of the Secured Parties), as to itself only, that:

          (a) Existence. The Pledgor is a limited liability company, duly organized, validly existing and in good standing under the laws of Delaware. The Pledgor is duly qualified to do business and is in good standing in each jurisdiction in which such qualification is required by Applicable Law, except where the failure to so qualify would not reasonably be expected to have a Material Adverse Effect. The Pledgor has all requisite power and authority and legal right (i) to own its properties and conduct its business substantially as contemplated by the Material Project Documents and Financing Documents to which it is a party and (ii) to execute,

deliver, and perform its obligations under each Transaction Document to which it is a party and to consummate each of the transactions contemplated herein and therein.

          (b) Litigation. Except as set forth on Schedule 3.07 to the Credit Agreement, there are no actions, suits, proceedings, investigations or similar actions pending or, to the knowledge of the Pledgor, threatened (in writing) against the Pledgor that has had or could reasonably be expected to have a Material Adverse Effect.

          (c) No Breach. The execution, delivery and performance by the Pledgor of this Agreement and the performance of its obligations thereunder do not and will not (i) violate the articles of organization or other organizational documents of the Pledgor, (ii) violate any provision of any Applicable Law, (iii) result in a breach of or constitute a default under any indenture or loan or credit agreement or any other material agreement, lease, or instrument to which the Pledgor is a party or by which it or its properties may be bound or affected, or (iv) result in or require the creation or imposition of any Lien of any nature (other than any Permitted Encumbrance) upon or with respect to any of the properties now owned or hereafter acquired by such Loan Party except, in the case of (ii) and (iii), as would not reasonably be expected to have a Material Adverse Effect.

          (d) Organizational Action. The execution, delivery, and performance of this Agreement has been duly authorized by all necessary action on the part of the Pledgor. This Agreement has been duly executed and delivered by the Pledgor. This Agreement constitutes a legal, valid and binding obligation of the Pledgor, enforceable in accordance with its respective terms, subject to bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium, and similar laws of general applicability relating to or affecting creditors’ rights and to general principles of equity (regardless of whether such enforceability is considered in a proceeding in equity or at law).

          (e) Title.

          (i) The Pledgor is the legal and beneficial owner of and has good title to the Collateral free and clear of all Liens, except for the security interest created by this Agreement and any Permitted Encumbrances.

          (ii) No effective financing statement or other instrument similar in effect covering all or any part of the Collateral is on file in any recording office, except such as may have been filed in favor of the Collateral Agent relating to this Agreement.

          (iii) The Membership Interests are “certificated securities” as such term in defined in Article 8 of the UCC.

          (f) Valid Security. This Agreement creates a valid security interest in the Collateral securing the payment of all the Secured Obligations.

          (g) Financing Statements. The appropriate financing statements (the “Financing Statements”) have been presented (or are in a form to be presented immediately

following the Closing Date) for filing under the Uniform Commercial Code (the “UCC”) as in effect in the jurisdiction of the Pledgor’s formation.

                    (h) Authorizations and Perfection. Except for the filing of the Financing Statements, no consent of any other Person and no Governmental Approvals or other action by, or notice to or filing with, any other Person is required for (i) the execution, delivery or performance by the Pledgor of this Agreement, except to the extent that the failure to obtain, maintain, make or provide any such consent, Governmental Approvals, other action, filing or notice could not reasonably be expected to have a Material Adverse Effect on the ability of the Pledgor to perform its obligations hereunder, (ii) the pledge and assignment by the Pledgor of the Collateral pursuant to this Agreement, (iii) the validity, perfection or maintenance of the security interest created hereby or (iv) the exercise by the Collateral Agent of the voting or other rights provided for in this Agreement or the remedies in respect of such Collateral pursuant to this Agreement or as provided by law, except for those which have been duly obtained or made and, in the case of the maintenance of perfection, for the filing of continuation statements under the UCC, and as may be required in connection with any disposition of any portion of the Collateral (x) by laws affecting the offering and sale of securities generally, (y) by laws regulating the ownership or transfer of public utilities or electric utilities or their assets or (z) pursuant to the ▇▇▇▇-▇▇▇▇▇-▇▇▇▇▇▇ Antitrust Improvements Act of 1976, as amended, and any applicable foreign competition laws.

                    (i) Names; Changes in Circumstances. The full and correct legal name, type of organization, jurisdiction of organization and organizational ID number (if applicable) of the Pledgor as of the date hereof are correctly set forth in Annex 2. The Pledgor has not (a) within the period of four months prior to the date hereof, changed its location (as defined in Section 9-307 of the UCC), (b) except as specified in Annex 2, heretofore changed its name, or (c) except as specified in Annex 3, heretofore become a “new debtor” (as defined in Section 9-102(a)(56) of the UCC) with respect to a currently effective security agreement previously entered into by any other Person.

                    (j) Pledged Interests. As at the date hereof (a) the Membership Interests identified in Annex 1 constitute all of the issued and outstanding membership interest in the Borrower and (b) there are no other issued and outstanding membership interests in the Borrower.

                    (k) Options, Restrictions, Etc. There are no outstanding agreements, options and contracts to sell all or any portion of the Collateral. No part of the Collateral is subject to the terms of any agreement restricting the sale or transfer of such Collateral, except for the Secured Obligation Documents and the Borrower Operating Agreement. No Person has any right to purchase or terminate any or all of the membership interests in the Borrower except pursuant to the terms of this Agreement, any other Secured Obligation Document and the Borrower Operating Agreement.

                    (l) Compliance with Laws and Obligations. The Pledgor is in compliance with all Applicable Laws, except to the extent that non-compliance with such Applicable Laws could not, individually or in the aggregate, reasonably expected to have a Material Adverse Effect.

          SECTION 5. Covenants. The Pledgor covenants and agrees that:

          (a) Books and Records. The Pledgor shall:

          (i) keep full and accurate books and records relating to the Collateral, and, to the extent requested by the Collateral Agent, stamp or otherwise ▇▇▇▇ such books and records in such manner as the Collateral Agent may reasonably require in order to reflect the security interests granted by this Agreement; and

          (ii) permit officers and designated representatives of the Collateral Agent to examine and make copies of the books, records and documents of the Pledgor and to discuss the affairs, finances and accounts of the Pledgor with the Pledgor’s principal officers and independent accountants (subject to reasonable requirements of safety and confidentiality, including requirements imposed by Applicable Law or by contract) with the participation of the Pledgor with reasonable advance notice to the Pledgor and during normal business hours of the Pledgor.

          (b) Performance of the Borrower Operating Agreement. The Pledgor shall not, without the written consent of the Collateral Agent, cancel or terminate the Borrower Operating Agreement or consent to or accept any cancellation or termination thereof; amend or otherwise modify the Borrower Operating Agreement in any material respect if such amendment or modification would materially impair the value of the interest or rights of the Pledgor thereunder; or waive any material default under or material breach of the Borrower Operating Agreement, except in each case as permitted by the Financing Documents. In addition, it will not consent to any transaction for the termination, dissolution or winding up of, or the merger or consolidation with any other Person by, the admission of additional members to, or otherwise effect or change the structure or organization of the Borrower, except in each case as permitted by the Financing Documents.

          (c) Defense of Collateral. The Pledgor will defend the Collateral against all claims and demands of all Persons (other than the Collateral Agent and the other Secured Parties and the holders of Permitted Encumbrances) claiming an interest in any of the Collateral. It will discharge or cause to be discharged all Liens on any or all of the Collateral, except for the security interests under this Agreement and Permitted Encumbrances.

          (d) Location of Office; Name. The Pledgor shall keep its principal place of business, where it keeps its records concerning the Collateral, at its address specified on the signature page hereof; or, upon 30 days’ prior written notice to the Collateral Agent, at such other location in a jurisdiction where all action required by Section 6 shall have been taken with respect to the Collateral. Without at least 30 days’ prior written notice to the Collateral Agent, the Pledgor shall not change its name from or its jurisdiction of organization from the name or jurisdiction, respectively, set forth in Annex 2.

          (e) Disposition of Collateral. Unless permitted by the Financing Documents, the Pledgor shall not transfer, sell, assign (by operation of law or otherwise) or otherwise dispose of any of the Collateral (other than the pledge, hypothecation and security interest created pursuant to this Agreement) unless (i) such transfer, sale, assignment or disposition would not

violate any Applicable Law or Governmental Approvals, and the Agents shall have received an opinion of counsel to the effect that such transfer, sale, assignment or disposition will not cause the Project to be in violation with any material Governmental Approvals or any Project Document, (ii) no Default or Event of Default shall have occurred and be continuing at the time of such transfer, sale, assignment or disposition or would result therefrom, (iii) no Change of Control will result from such transfer, sale, assignment or disposition, (iv) such transfer, sale, assignment or disposition could not reasonably be expected to have a Material Adverse Effect, and (v) the Person to acquire such Collateral shall become a party to this Agreement by executing an assumption agreement pursuant to Section 20, and such Person shall deliver such evidence of corporate action, opinions of counsel and such other documentation with respect to such assumption agreement and this Agreement.

          (f) Liens. The Pledgor will not create, incur, assume or suffer to exist any Lien upon any Collateral (other than Permitted Encumbrances) or file or suffer to be on file or authorize to be filed, in any jurisdiction, any financing statement or like instrument with respect to all or any part of the Collateral in which the Collateral Agent is not named as the sole secured party for the benefit of the Secured Parties.

          (g) Voting Rights. The Pledgor shall exercise any and all management, voting and other consensual rights pertaining to the Borrower Operating Agreement and the Borrower, in a manner which is not inconsistent with the terms of this Agreement and the other Secured Obligation Documents.

          (h) Maintenance of Existence. The Pledgor shall preserve and maintain its legal existence as a Delaware limited liability company; provided, that, the Pledgor may convert its form to another Delaware entity if (A) to the extent required to maintain the Lien of the Collateral Agent in the Membership Interests, the Pledgor enters into another pledge agreement having substantially similar terms as provided herein, granting a Lien to the Collateral Agent in the Membership Interests and (B) such change of legal form would not result in a Secured Obligation Default or Secured Obligation Event of Default or a default under any Material Project Document that would reasonably be expected to have a Material Adverse Effect.

          SECTION 6. Continued Perfection of Security Interest.

          (a) The Pledgor agrees that it will not take any actions or fail to perform any of its duties or obligations under this Agreement so that after giving effect to such action or inaction the Collateral Agent will not then, or with the passage of time cease to, have a perfected security interest in any of the Collateral.

          (b) Concurrently with the execution herewith, the Pledgor shall deliver all certificates or instruments representing or evidencing the Collateral to Collateral Agent, if any, and all such certificates or instruments shall be accompanied by duly executed instruments of transfer or assignment in blank, all in form and substance acceptable to Collateral Agent. Collateral Agent shall have sole possession and control of such certificates and instruments until payment in full of the Secured Obligations. Collateral Agent shall have the right, at any time in its discretion, upon the occurrence and during the continuation of an Event of Default and upon notice to the Pledgor (but only where such notice may be given without violating Applicable

Law), to transfer to or to register in the name of Collateral Agent or any of its nominees any or all of the Collateral and to exchange certificates or instruments representing or evidencing the Collateral for certificates or instruments of smaller or larger denominations.

          (c) The Pledgor agrees that from time to time the Pledgor shall take or cause to be taken all action reasonably required to maintain the security interests (and the priority of such security interest) in the Collateral granted hereunder. The Pledgor shall execute, file and record or cause to be executed, filed and recorded any and all further instruments (including financing statements, continuation statements and similar statements with respect to any Security Document) as reasonably requested by the Collateral Agent for such purpose, including the payment of all associated fees and other charges in connection therewith. The Pledgor shall discharge any Lien (other than Permitted Encumbrances) on the Collateral to which it has an interest.

          (d) The Pledgor hereby further authorizes the Collateral Agent to file one or more financing or continuation statements, and amendments thereto, relative to all or any part of the Collateral without the signature of such Pledgor where permitted by law. Unless as directed by the Pledgor or the Administrative Agent in writing (and subject to clause (d) of Section 9.03(a) of the Credit Agreement) to prepare, file or record any financing statement, continuation statement or other instrument or ensure the preparation, filing or recording of the same, the Collateral Agent has no obligation to prepare, file or record any financing statement, continuation statement or other instrument or ensure the preparation, filing or recording of the same.

          (e) With respect to any Collateral that constitutes an uncertificated security, to the extent that the Borrower has elected to have its Membership Interests governed by Article 8 of the UCC, the Pledgor will cause the Borrower to either (i) register the Collateral Agent as the registered owner of such security or (ii) agree with such Pledgor and Collateral Agent that the Borrower will comply with instructions with respect to such security originated by the Collateral Agent without further consent of the Pledgor, such agreement to be in form and substance satisfactory to the Administrative Agent (such agreement being an “Uncertificated Security Control Agreement”).

          SECTION 7. Pledgor’s Rights.

          (a) Voting Rights. Unless a Secured Obligation Event of Default shall have occurred and be continuing, the Pledgor shall be entitled to exercise all voting and other rights with respect to the Collateral; provided, however, that no vote shall be cast, right exercised or other action taken by the Pledgor which (i) could reasonably be expected have a Material Adverse Effect or (ii) is inconsistent with Section 5(g).

          (b) Distributions. All distributions paid or payable in respect of the Membership Interests of the Pledgor may be paid to and retained by the Pledgor to the extent not prohibited by the Credit Agreement or any other Financing Document. During the continuance of any Secured Obligation Event of Default, any and all distributions paid or payable in respect of the Membership Interests (whether paid in cash, securities or other property) shall be, and shall be forthwith delivered to the Collateral Agent to hold as Collateral and shall, if received by

any Pledgor, be received in trust for the benefit of the Collateral Agent, shall be segregated from other funds of such Pledgor and shall be forthwith paid over to the Collateral Agent in the same form as so received (with any necessary indorsement).

          SECTION 8. Obligations of the Pledgor and Rights of Collateral Agent. Anything herein to the contrary notwithstanding, (a) the Pledgor shall remain liable under the Borrower Operating Agreement to the extent set forth therein to perform all of its duties and obligations thereunder to the same extent as if this Agreement had not been executed, (b) the exercise by the Collateral Agent of any of the rights hereunder shall not release the Pledgor from any of its duties or obligations under the Borrower Operating Agreement and (c) neither the Collateral Agent nor any other Secured Party shall have any obligation or liability under the Borrower Operating Agreement by reason of this Agreement, nor shall the Collateral Agent or any other Secured Party be obligated to perform any of the obligations or duties of the Pledgor thereunder or to take any action to collect or enforce any claim assigned hereunder, unless the Collateral Agent has agreed in writing to be so obligated.

          If the Pledgor fails to perform any agreement contained herein, subject to receipt of notice from the Collateral Agent and after applicable cure periods, the Collateral Agent may itself perform, or cause performance of, such agreement and the Collateral Agent shall deliver a written notification to the Pledgor of such decision to perform, or cause the performance of, any such agreement, and the Collateral Agent shall exercise reasonable care and act diligently in all such cases, and the expenses of the Collateral Agent incurred in connection therewith shall be payable by the Pledgor under Section 11.

          The powers conferred on the Collateral Agent hereunder are solely to protect its interest in the Collateral and shall not impose any duty upon it to exercise any such powers. Except for the safe custody of any Collateral in its possession and the accounting for moneys actually received by it hereunder, and the duties set forth in Section 9-207 of the Uniform Commercial Code, the Collateral Agent shall have no duty as to any Collateral or as to the taking of any necessary steps to preserve rights against prior parties or any other rights pertaining to any Collateral, unless the Collateral Agent has agreed in writing to be so obligated.

          Notwithstanding anything else to the contrary herein, whenever reference is made in this Agreement to any discretionary action by, consent, designation, specification, requirement or approval of, notice, request or other communication from, or other direction given or action to be undertaken or to be (or not to be) suffered or omitted by the Collateral Agent or to any election, decision, opinion, acceptance, use of judgment, expression of satisfaction or other exercise of discretion, rights or remedies to be made (or not to be made) by the Collateral Agent, it is understood that in all cases the Collateral Agent shall be fully justified in failing or refusing to take any such action under this Agreement if it shall not have received such written instruction, advice or concurrence of the Administrative Agent (acting in accordance with the Credit Agreement and other Financing Documents), as it deems appropriate. This provision is intended solely for the benefit of the Collateral Agent and its successors and permitted assigns and is not intended to and will not entitle the other parties hereto to any defense, claim or counterclaim, or confer any rights or benefits on any party hereto.

          SECTION 9. Remedies of Collateral Agent. At any time after a Secured Obligation Event of Default occurs and is continuing, the Collateral Agent has the right to do any or all of the following:

          (a) The Collateral Agent may exercise any and all rights and remedies of the Pledgor under or in connection with the Borrower Operating Agreement, the Membership Interests or otherwise in respect of the Collateral, including, without limitation, any and all rights of such Pledgor to demand or otherwise require payment of any amount under, or performance of any provision of, the Borrower Operating Agreement and all rights of such Pledgor to control the operations of the Borrower. In addition, the Collateral Agent may, but shall not be obligated to cure any default by the Pledgor under the Borrower Operating Agreement.

          (b) The Collateral Agent shall have the right in its discretion and without notice to the Pledgor, to transfer to or to register in the name of the Collateral Agent or any of its nominees any or all of the Collateral.

          (c) Upon written notice of the Collateral Agent to the Pledgor, all rights of the Pledgor to exercise or refrain from exercising the voting and other consensual rights which it would otherwise be entitled to exercise shall cease, and all such rights shall thereupon become vested in the Collateral Agent who shall thereupon, so long as the Secured Obligation Event of Default is continuing, have the sole right to exercise or refrain from exercising in a reasonable manner such voting and other consensual rights in aid of foreclosure or other enforcement of its security interest in the Collateral.

          (d) The Collateral Agent may (i) notify the Borrower to make payment and performance due to the Pledgor under the Borrower Operating Agreement to the Collateral Agent, (ii) extend the time of payment and performance of, or compromise or settle for cash, credit or otherwise, and upon any terms and conditions, the obligations of the Pledgor under the Borrower Operating Agreement, (iii) file any claims, commence, maintain, settle or discontinue any actions, suits or other proceedings deemed by the Collateral Agent in its sole discretion necessary or advisable for the purpose of collecting upon the Collateral or enforcing the Borrower Operating Agreement, and (iv) execute any instrument and do all other things deemed necessary and proper by the Collateral Agent in its sole discretion to protect and preserve and permit the Collateral Agent to realize upon the Collateral and the other rights contemplated thereby.

          (e) The Collateral Agent may exercise in respect of the Collateral, in addition to other rights and remedies provided for herein or otherwise available to it, all the rights and remedies of a secured party upon default under the UCC, and may also, without notice except as specified below, sell the Collateral or any part thereof in one or more parcels at public or private sale, at any exchange, broker’s board or at any of the Collateral Agent’s offices or elsewhere, for cash, on credit or for future delivery, and upon such other terms as the Collateral Agent may deem commercially reasonable. The Pledgor agrees that, to the extent notice of sale shall be required by law, at least 10 days’ written notice, in a manner provided in Section 14, to the Pledgor of the time and place of any public sale or the time after which any private sale is to be made shall constitute reasonable notification. The Collateral Agent shall not be obligated to make any sale of Collateral regardless of notice of sale having been given. The Collateral Agent

may adjourn any public or private sale from time to time by announcement at the time and place fixed therefor, and such sale may, without further notice, be made at the time and place to which it was so adjourned.

          (f) In view of the position of the Pledgor in relation to the Collateral, or because of other current or future circumstances, questions may arise under the Securities Act of 1933, as now or hereafter in effect, or any similar statute hereafter enacted analogous in purpose or effect (such act and any such similar statute as from time to time in effect being called the “Federal Securities Laws”) with respect to any disposition of the Collateral permitted hereunder. The Pledgor understands that compliance with the Federal Securities Laws might very strictly limit the course of conduct of the Collateral Agent if the Collateral Agent were to attempt to dispose of all or any part of the Collateral, and might also limit the extent to which or the manner in which any subsequent transferee of any Collateral could dispose of the same. Similarly, there may be other legal restrictions or limitations affecting the Collateral Agent in any attempt to dispose of all or part of the Collateral under applicable Blue Sky or other state securities laws or similar laws analogous in purpose or effect. The Pledgor recognizes that in light of the foregoing restrictions and limitations the Collateral Agent may, with respect to any sale of Collateral, to the extent commercially reasonable, limit the purchasers to those who will agree, among other things, to acquire Collateral for their own account, for investment, and not with a view to the distribution or resale thereof. The Pledgor acknowledges and agrees that, in light of the foregoing restrictions and limitations, the Collateral Agent, in a commercially reasonable manner, (i) may proceed to make such a sale whether or not a registration statement for the purpose of registering the Collateral or part thereof shall have been filed under the Federal Securities Laws and (ii) may approach and negotiate with a single possible purchaser to effect such sale. The Pledgor acknowledges and agrees that any such sale might result in prices and other terms less favorable to the seller than if such sale were a public sale without such restrictions. In the event of any such sale, neither the Collateral Agent nor any other Secured Party shall incur any responsibility or liability for selling all or any part of the Collateral at a price that the Collateral Agent, in a commercially reasonable manner, may in good ▇▇▇▇▇ ▇▇▇▇ reasonable under the circumstances, notwithstanding the possibility that a higher price might have been realized if the sale were deferred until after registration as aforesaid or if more than a single purchaser were approached. The provisions of this paragraph will apply notwithstanding the existence of a public or private market upon which the quotations or sales prices may exceed the price at which the Collateral Agent sells. The Pledgor agrees that sales made pursuant to this paragraph are made in a commercially reasonable manner.

security by the Collateral Agent; or (d) any invalidity, irregularity or unenforceability of all or part of the Secured Obligations or of any security therefor.

          SECTION 13. Amendments; Etc.

          SECTION 16. Severability. If any provision of this Agreement shall be held or deemed to be or shall, in fact, be illegal, inoperative or unenforceable, the same shall not affect any other provision or provisions herein contained or render the same invalid, inoperative or unenforceable to any extent whatever.

          SECTION 20. Additional Pledgors. One or more Qualifying Transferees may become party to this Agreement by executing and delivering to each Agent an assumption agreement substantially in the form of Exhibit A hereto, in which case such Qualifying Transferee shall, from and after the date of such execution and delivery, be for all purposes a “Pledgor” hereunder and the Annexes hereto shall be supplemented in the manner specified in
