24

4.Statute of Limitations. Any payment by the Borrowers or other circumstance that operates to toll any statute of limitations as to the Borrowers shall operate to toll the statute of limitations as to the Guarantor, except to the extent that any statute of limitations as to the Borrowers is tolled in respect of any action taken by a Borrower when such Borrower is controlled by the Lender following the exercise by the Lender of its remedies under the First Wind Holdings Pledge Agreement.

Any material portion of the Collateral is lost or seized without the Collateral Agent being compensated for such loss;

(vii)Any Obligor that is a party to a Basic Document shall fail to duly perform or observe in any material respect any of its obligations contained in this Agreement or any other Basic Document (except for any obligations specifically identified in this Section 6) and, in each case, such failure shall continue unremedied for a period of thirty (30) days; provided, that such breach of an obligation is susceptible to a cure within applicable cure period; provided, further, that such Obligor is diligently pursuing such a cure;

(viii)The Guarantor or any other Obligor, as applicable (A) shall admit in writing its inability to pay its debts as its debts become due; (B) shall make an assignment for the benefit of creditors, or petition or apply to any tribunal for the appointment of a custodian, receiver or trustee for its or a substantial part of its assets; (C) shall commence any proceeding under any applicable bankruptcy or reorganization law with respect to itself or shall apply for arrangement, readjustment of debt, dissolution or liquidation; (D) shall have had any such petition filed, or any such proceeding shall have been commenced against it, by any Person that is not an Affiliate of the Guarantor or any Borrower in which an adjudication is made or order for relief is entered or which remains undismissed for a period of sixty (60) days; (E) shall have had a receiver, custodian or trustee appointed for all or a substantial part of its property; (F) solely with respect to the Guarantor, shall commence any proceeding under any applicable bankruptcy or reorganization law against any other Obligor or shall apply for arrangement, readjustment of debt, dissolution or liquidation of any other Obligor; or (G) shall take any action effectuating, approving or consenting to any of the events described in clauses (A) through (G);

26

(x)Any Material Project Document shall cease to be in full force and effect before its scheduled expiration and such termination could reasonably be expected to constitute a Material Adverse Effect unless the Guarantor, within thirty (30) days after such default, replaces such Material Project Document with a replacement agreement, reasonably satisfactory in form and substance to the Administrative Agent;

(xi)Any applicable permit or governmental approval necessary for the development, construction, operation or maintenance of a Eligible Qualified Project shall be materially modified (in a manner that would reasonably be expected to constitute a Material Adverse Effect), revoked or cancelled by the issuing agency or other governmental authority having jurisdiction over the Eligible Qualified Project or the Guarantor shall fail to obtain, renew or maintain any required permit or governmental approval (in a manner that would reasonably be expected to constitute a Material Adverse Effect), unless such permit or governmental approval is reinstated within thirty (30) days of such modification, revocation or cancellation;

(xii)A final judgment or judgments shall be entered against the Guarantor or any other Obligor by a court of competent jurisdiction in an aggregate amount of not less than $150,000, other than (A) a judgment which is fully covered by a posted bond or discharged within thirty (30) days after its entry, or (B) a judgment, the execution of which is effectively stayed within thirty (30) days after its entry but only for thirty (30) days after the date on which such stay is terminated or expires; or

(xii)Any event, occurrence, circumstance occurs which results in a Material Adverse Effect.

(b)During the continuance of an Event of Default hereunder or the continuance of an event of default under any of the Turbine Supply Documents, the Lender may treat all Guaranteed Obligations as due and payable and may make a demand on the Guarantor for payment of all of the Guaranteed Obligations at any time (a “Demand”). The Guarantor shall pay the amount requested under any Demand promptly and in any event within thirty-five (35) days after the date on which such Demand has been made.

(c)In making any Demand under this Guaranty, the Lender shall specify whether the amount so demanded is to be applied to the payment of amounts owing by each Borrower under its respective FW Credit Facility. Unless agreed otherwise by the applicable Borrower and the Lender, all amounts paid in satisfaction of such Demand in accordance with this Guaranty shall be applied to the payment of amounts owing by such Borrower under the Turbine Supply Documents, unless (i) (A) the amount of Loans available to be borrowed by such Borrower under its respective FW Credit Facility (taking into account any applicable event of default or other circumstance that may limit the availability of Loans) is less than (B) the total amount then owing by such Borrower under the Turbine Supply Documents, and (ii) the amount of principal, interest and other amounts owing to the Lender under the applicable FW Credit Facility is greater than the amount that the Lender reasonably determines it could realize upon a foreclosure pursuant to the Security Agreements under any FW Credit Facility on the Turbines and the Turbine Supply Documents (taking into account the

27

insufficiency of available Loans and equity capital to meet the Borrowers’ obligations under the Turbine Supply Documents).

7.Modifications, Amendments and Extensions. The Lender may at any time and from time to time without the consent of, or notice to, the Guarantor, without incurring responsibility to the Guarantor, without impairing or releasing the obligations of the Guarantor hereunder, upon or without any terms or conditions and in whole or in part:

(a)change the manner, place or terms of payment of, and/or change, increase or extend the time of payment of, renew or alter, any of the Guaranteed Obligations (including any increase or decrease in the rate of interest thereon or the principal amount thereof) or any liability incurred directly or indirectly in respect thereof, and this Guaranty shall apply to the Guaranteed Obligations as so changed, extended, renewed or altered;

(b)take and hold security for the payment of the Guaranteed Obligations and sell, exchange, release, surrender, impair, realize upon or otherwise deal with in any manner and in any order any property by whomsoever at any time pledged or mortgaged to secure, or howsoever securing, the Guaranteed Obligations or any liabilities (including any of those hereunder) incurred directly or indirectly in respect thereof or hereof, and/or any offset there against;

(c)exercise or refrain from exercising any rights against the Borrowers or any subsidiary thereof or otherwise act or refrain from acting;

(d)release or substitute any one or more endorsers, other guarantors, the Borrowers or other obligors;

(e)settle or compromise any of the Guaranteed Obligations or any liability (including any of those hereunder) incurred directly or indirectly in respect thereof or hereof, or subordinate the payment of all or any part thereof to the payment of any liability (whether due or not) of the Borrowers to creditors of the Borrowers other than the Lender;

(f)apply any sums by whomsoever paid or howsoever realized to any liability or liabilities of the Borrowers to the Lender regardless of what liabilities of the Borrowers remain unpaid;

(g)consent to or waive any breach of, or any act, omission or default under, the Basic Documents or any of the instruments or agreements referred to therein, or otherwise amend, modify or supplement the Basic Documents or any of such other instruments or agreements;

(h)act or fail to act in any manner referred to in this Guaranty that may deprive the Guarantor of its right to subrogation against the Borrowers to recover full indemnity for any payments made pursuant to this Guaranty; or

28

(i)       take any other action which would, under otherwise applicable principles of common law, give rise to a legal or equitable discharge of the Guarantor from its liabilities under this Guaranty.

8.        No Waiver of Rights. This Guaranty is a continuing one and all liabilities to which it applies or may apply under the terms hereof shall be conclusively presumed to have been created in reliance hereon. No failure or delay on the part of the Lender in exercising any right, power or privilege hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any right, power or privilege hereunder preclude any other or further exercise thereof or the exercise of any other right, power or privilege. The rights and remedies herein expressly specified are cumulative and not exclusive of any rights or remedies which the Lender would otherwise have. No notice to or demand on the Guarantor in any case shall entitle the Guarantor to any other further notice or demand in similar or other circumstances, or constitute a waiver of the rights of the Lender to any other or further action in any circumstances without notice or demand. It is not necessary for the Lender to inquire into the capacity or powers of the Borrowers or the officers, directors, partners or agents acting or purporting to act on their behalves, and any indebtedness made or created in reliance upon the professed exercise of such powers shall constitute Guaranteed Obligations.

9.        Subordination; Subrogation. Any indebtedness of the Borrowers now or hereafter held by the Guarantor is hereby subordinated to the indebtedness of the Borrowers to the Lender. Without limiting the generality of the foregoing, the Guarantor hereby agrees with the Lender that it will not exercise any right of subrogation which it may at any time otherwise have as a result of this Guaranty (whether contractual, under Section 509 of the Bankruptcy Code or otherwise) until all Guaranteed Obligations have been irrevocably paid in full in cash.

10.      Certain Waivers.

(a)      The Guarantor waives any right (except as shall be required by applicable law and cannot be waived) to require the Lender to: (i) proceed against the Borrowers, any other guarantor or any other party; (ii) proceed against or exhaust any security held from the Borrowers, any other guarantor or any other party; or (iii) pursue any other remedy in the Lender’s power whatsoever. The Guarantor waives any defense based on or arising out of any defense of the Borrowers, any other guarantor or any other party other than payment in full of the Guaranteed Obligations, including, without limitation, any defense based on or arising out of the disability of the Borrowers, any other guarantor or any other party, or the unenforceability of the Guaranteed Obligations or any part thereof from any cause, or the cessation from any cause of the liability of the Borrowers other than payment in full of the Guaranteed Obligations.

(b)      Except as otherwise expressly provided in this Guaranty, the Guarantor hereby waives (to the fullest extent permitted by applicable laws) notice of acceptance of this Guaranty and notice of any liability to which it may apply, and waives promptness, diligence, presentment, demand of payment, protest, notice of dishonor or nonpayment of any such liabilities, suit or taking of other action by the Lender against, and any other notice to, any party liable thereon (including the Guarantor, any other guarantor or the Borrowers). The Guarantor assumes all responsibility for being and keeping itself informed of the Borrowers’ financial condition and assets, and of all other circumstances bearing upon the risk of

29

nonpayment of the Guaranteed Obligations and the nature, scope and extent of the risks which the Guarantor assumes and incurs hereunder, and agrees that the Lender shall have no duty to advise the Guarantor of information known to them regarding such circumstances or risks.

11.      Representations and Warranties. The Guarantor hereby makes the following representations and warranties as of the date hereof:

(a)     The Guarantor is a limited liability company validly existing and in good standing under the laws of the State of Delaware; and the Guarantor is duly qualified and in good standing (or the equivalent) as a foreign company authorized to do business in each jurisdiction where the failure to so qualify would materially and adversely affect the Guarantor’s ability to perform its obligations hereunder.

(b)     The Guarantor’s execution, delivery and performance of this Guaranty are within the Guarantor’s powers, have been duly authorized by all necessary limited liability company action and do not require any governmental, regulatory or other approval.

(c)     The Guarantor’s execution, delivery and performance of this Guaranty do not contravene or conflict with any provision of (i) any applicable law, (ii) any judgment, decree or order, (iii) the Guarantor’s organizational documents or by-laws, or (iv) any instrument binding upon the Guarantor or upon any property of the Guarantor, such that, in case of any of clauses (i), (ii) and (iv), there would be a material adverse effect on the ability of the Guarantor to comply with its obligations under this Guaranty.

(d)      This Guaranty is a legal, valid and binding obligation of the Guarantor enforceable against the Guarantor in accordance with its terms, except as such enforceability may be affected by applicable bankruptcy, insolvency, moratorium or other similar laws affecting creditors rights generally and the applicable of general principles of equity.

(e)     No litigation, arbitration proceedings, governmental proceedings or investigations or regulatory proceedings are pending or, to the knowledge of the Guarantor, threatened against the Guarantor that, if adversely determined, could reasonably be expected to have a material adverse effect on the ability of the Guarantor to comply with its obligations under this Guaranty.

(f)      The Guarantor has obtained all licenses, permits, franchises and other governmental authorizations necessary to the ownership of its properties or to the conduct of its businesses, a failure to obtain or violation of which could reasonably be expected to adversely affect the Guarantor’s business, credit, operations or financial condition or its ability to perform its obligations hereunder.

(f)      After giving effect to the transactions contemplated hereby, the Guarantor is not nor would be deemed to be insolvent, nor does the Guarantor’s incurrence of contingent obligations under this Guaranty render the Guarantor insolvent.

(g)     The Guarantor is in compliance with the requirements of all applicable laws, rules, regulations, and orders of all governmental authorities (including, without

30

limitation, environmental laws, rules, regulations and orders), a breach of which would materially and adversely affect the Guarantor’s ability to perform its obligations hereunder.

12.      Expenses; Indemnification.

(a)     The Guarantor agrees hereby to reimburse the Lender and the Collateral Agent, together with their respective Affiliates, successors and assigns, directors, officers, employees, agents, advisors, controlling persons and members of each of the foregoing (each, an “Indemnified Party”), on demand for all costs, expenses and charges incurred by the Indemnified Parties in connection with the negotiation, performance or administration of this Guaranty (including, without limitation, reasonable fees, disbursements and other reasonable documented out-of-pocket charges of legal counsel, consultants and advisors to the Indemnified Parties). The Guarantor agrees hereby to reimburse the Indemnified Parties for all costs, expenses and charges incurred by the Indemnified Parties in connection with any enforcement (including in any workout, restructuring or bankruptcy proceeding) of this Guaranty or the defense or prosecution of any rights of the Indemnified Parties hereunder.

(b)     The Guarantor agrees hereby to indemnify and hold the Indemnified Parties harmless against all claims, damages, losses, liabilities, costs, deficiencies and expenses, including, without limitation, investigative costs, settlement costs and reasonable legal, accounting or other reasonable documented out-of-pocket expenses for investigating or defending against any actions or threatened actions (collectively, the “Losses”), arising out of or in connection with the execution or delivery of this Guaranty, and the performance by the Guarantor of its obligations hereunder and any prospective claim, litigation, investigation or proceeding related to the foregoing, regardless of whether such Indemnified Person is a party hereto, but excluding, in each case, any such Losses to the extent determined in the final, non-appealable judgment of a court of competent jurisdiction to have incurred primarily by reason of the bad faith, gross negligence or willful misconduct of any Indemnified Person. The Lender and/or the Collateral Agent, as applicable, shall promptly notify the Guarantor of any claim under this Section 12(b). The Guarantor may elect to assume the defense of any action, proceeding or dispute with a third party in respect of which a claim is to be made under this Section 12(b); provided, however, that if the Guarantor assumes control of the defense of any such action, proceeding or dispute, the Guarantor shall not agree or conclude any settlement that affects the Lender or the Collateral Agent without the prior written approval of the Lender or the Collateral Agent, as applicable (such approval not to be unreasonably withheld). In the event the Guarantor assumes control of the defense of any such action, proceeding or dispute, the Guarantor shall not be liable to Lender or the Collateral Agent for any reasonable legal fees and reasonable documented out-of-pocket expenses of additional counsel incurred by the Lender or the Collateral Agent in connection with such defense; provided, however, that each of the Lender and the Collateral Agent shall have the right to employ its own counsel, it being understood, however, that the Guarantor shall not be liable for the expenses of more than one counsel for each Indemnified Party (unless counsel in any jurisdiction other than New York is required for each or any of the Lender and the Collateral Agent), whose reasonable legal fees and reasonable documented out-of-pocket expenses shall be indemnified by the Guarantor if (A) there is or could reasonably be expected to be a conflict of interest between the Lender or the Collateral Agent, as applicable, and the Guarantor in connection with the defense of such action,

31

proceeding or dispute, or (B) there is a specific defense available to the Lender or the Collateral Agent, as applicable, which is different from or additional to those available to the Guarantor, or (C) it is reasonably necessary to protect the interests of the Lender or the Collateral Agent, as applicable, to the extent such interests differ from the interests of the Guarantor. The Guarantor agrees hereby to indemnify and hold the Indemnified Parties harmless for the full amount of taxes (excluding taxes imposed on or measured by the income or capital of the Indemnified Parties or any branch profits taxes imposed by the United States or any other jurisdiction) arising from the execution, delivery or performance of its obligations or from receiving a payment under this Guaranty, or any liability (including penalties, interest and expenses) arising therefrom or with respect thereto, whether or not such taxes have been correctly assessed by the applicable governmental agency; provided, however, that the Guarantor shall not be required to indemnify the Indemnified Parties for any penalties, interest or expenses relating to taxes arising from the Indemnified Parties’ bad faith gross negligence, willful misconduct or unexcused breach of this Guaranty.

13.      Successors and Assigns. This Guaranty shall be binding upon the Guarantor and its successors and assigns and shall inure to the benefit of the Lender and its successors and assigns.

32
