or prepayment of principal thereunder, and the Borrower agrees that all such notations shall constitute prima facie evidence of the matters noted in the absence of manifest error.

(w) Interest Rate Protection Agreements. The Borrower shall perform each of its obligations under Interest Rate Protection Agreements to which it is a party, except, in the case solely of obligations other than for payment of money, if such failure perform such non-payment obligations under such Interest Rate Protection Agreements would not reasonably be expected to cause a Material Adverse Effect.

(x) Qualified Project Determination. The Borrower shall deliver to the Administrative Agent a periodic desktop fatal flaw review (each, a “Project Review”) for all Eligible Qualified Projects, and from time to time as and when the Borrower desires to designate an Eligible Qualified Project as a Qualified Project (as defined below). Until receipt of such Project Reviews with respect to any Eligible Qualified Project and determination by the Administrative Agent that a Project is a Qualified Project, on each Top-Up Date, the Reduced Advance Rate shall be applied for Turbines allocated to such Eligible Qualified Project. Each Project Review shall be in form and substance reasonably satisfactory to the Majority Lenders and the Administrative Agent and shall be comprised solely of the following items and such additional information and relevant materials as the Borrower may provide the Administrative Agent:

(i) a written review by the Independent Engineer including, but not limited to, a confirmation of the potential viability, from a wind and technology point of view, of the wind electrical generating project proposed by the Borrower to be a Qualified Project (it being agreed that if a third-party desktop wind analysis has not been completed, or if such analysis has been prepared in respect of a different turbine layout, then the Independent Engineer may utilize the Borrower’s internal wind analysis in connection with the preparation of the written review hereunder. To the extent, however, that a third-party desktop wind analysis has been prepared for a Project site, such analysis must be presented to the Independent Engineer in conjunction with the Borrower’s internal wind study;

(ii) a pro-forma cash flow forecast demonstrating to the Administrative Agent’s reasonable satisfaction that such proposed wind electrical generating project is economically viable;

(iii) a detailed report setting forth the proposed real estate plan for the wind electrical generating project proposed by the Borrower to be a Qualified Project; and

(iv) a detailed report as to the permitting and interconnection plan for the wind electrical generating project proposed by the Borrower to be reviewed hereunder.

If the Project Review demonstrates to the Majority Lenders’ and the Administrative Agent’s reasonable satisfaction (in consultation with the Independent Engineer) that such Eligible Qualified Project could (x) reasonably achieve construction completion (taking into account the likelihood of such Project obtaining adequate construction financing but not taking into account any adverse effect thereon associated with Clipper being the manufacturer of Turbines included in such Project), qualify for PTCs and begin selling power at least sixty (60) days prior to the then-current expiration date (the “PTC Expiration Date”) for PTCs under the Code, (y) benefit from tax benefits similar to or better than the PTCs then applicable, taking into account the PTC Expiration Date, or (z) is otherwise economically viable without PTC benefits, such Project shall be deemed a Qualified Project (a “Qualified Project”).

The Administrative Agent shall provide notice to the Borrower within fifteen (15) Business Days after the receipt of any Project Review of its determination or a detailed description of the changes that the Administrative Agent and the Majority Lenders determine are reasonably necessary for such Eligible Qualified Project to qualify as a Qualified Project. The Borrower

may resubmit an updated Project Review for reconsideration under this Section 5(x). The resulting Advance Rates or Reduced Advance Rates, as the case may be, shall apply for purposes of determining the Top-Up Amount for Top-Up Dates.

(y) Qualified Project Status. The Borrower shall provide monthly updates to Project Reviews and project progress updates for all Eligible Qualified Projects, respectively, and shall (i) promptly notify Administrative Agent of any adverse changes with respect to the most recently provided Project Review (including any delays and project cost increases) for a Qualified Project to the extent such Qualified Project would no longer reasonably be expected to be a Qualified Project and (ii) promptly respond to inquiries by the Administrative Agent as to the status of any Qualified Project (including any potential delays and project cost increases) of each Qualified Project. If the Administrative Agent is notified or reasonably determines that any Qualified Project could no longer reasonably be expected to be a Qualified Project, such project will immediately cease to be a “Qualified Project” under the Loan and the Advance Rate, to the extent it is then in effect, shall be automatically reduced to the applicable Reduced Advance Rate. Without limiting the generality of the foregoing, promptly upon obtaining knowledge or notice thereof, but in no event later than five (5) Business Days thereafter, the Borrower shall provide the Administrative Agent with written notice of any delay in (or the occurrence of any other event with respect to) a Qualified Project to the extent such Qualified Project would no longer reasonably be expected to complete construction and qualify for PTCs that are necessary to the economic viability of the Qualified Project at least sixty (60) days prior to the PTC Expiration Date applicable to such Qualified Project. Additionally, the Borrower shall, promptly, but in no event later than ten (10) Business Days, respond to inquiries by the Administrative Agent as to the status of the development and construction schedule (including any potential delays and project cost increases) of each Qualified Project. If (I) the Administrative Agent is notified pursuant to this Section 5(y), or otherwise reasonably determines based on consultation with the Independent Engineer, that any Qualified Project for which PTC benefits are necessary to the economic viability of the Project would no longer reasonably be expected to achieve construction completion and qualify for PTCs at least sixty (60) days prior to the PTC Expiration Date applicable to such Qualified Project, such project will immediately cease to be a “Qualified Project” hereunder, and the Administrative Agent shall promptly notify the Borrower of any such determination made under this clause (I), and (II) if the Borrower disagrees with any determination by the Administrative Agent and/or the Independent Engineer that a Qualified Project would no longer reasonably be expected to remain a Qualified Project, the Borrower shall promptly, but in any event within ten (10) days, notify the Administrative Agent of such disagreement, and the parties hereby agree to submit the issue to ▇.▇. ▇▇▇▇ (or such other third party engineering firm as the Borrower and Administrative Agent may agree). If ▇.▇. ▇▇▇▇ (or such other third party engineering firm as the Borrower and the Administrative Agent may agree) agrees with the determination of the Administrative Agent and/or the Independent Engineer, such determination shall stand and the applicable Project shall no longer be a Qualified Project as of the date of the Administrative Agent’s determination. If ▇.▇. ▇▇▇▇ (or such other third party engineering firm as the Borrower and the Administrative Agent may agree) disagrees with the determination of the Administrative Agent and/or the Independent Engineer, such determination shall be overturned and the applicable project shall remain a Qualified Project. Whatever determination is made by ▇.▇. ▇▇▇▇ (or such other third party engineering firm as the Borrower and the Administrative Agent may agree) shall be final

and binding as to the parties’ respective rights and obligations under this Section 5(y). ▇.▇. ▇▇▇▇ (or such other third party engineering firm as the Borrower and the Administrative Agent may agree) shall have thirty (30) days to make its determination as to whether the applicable project is or is not a Qualified Project from the date ▇.▇. ▇▇▇▇ (or such other third party engineering firm as the Borrower and the Administrative Agent may agree) is retained to make such determination; provided, however, that to the extent that ▇.▇. ▇▇▇▇ (or such other third party engineering firm as the Borrower and the Administrative Agent may agree) is unable to make a determination as set forth in this Section 5(y) within such thirty (30) day period, the determination of the Administrative Agent and/or the Independent Engineer shall stand and the applicable project shall no longer be a Qualified Project (unless reinstated as a Qualified Project pursuant to resubmission thereof (which may not occur more than once per calendar quarter) pursuant to Section 5(x).

(z) Turbine Reallocation. Subject to the Turbine Supply Documents, the Borrower may request a reallocation of any Turbine to any specified Eligible Qualified Project, Qualified Project or other single-purpose project company owned directly or indirectly by the Borrower (which such project shall be deemed an Eligible Qualified Project and which project company shall be deemed a Corresponding Project Company hereunder), subject to the approval of the Majority Lenders and the Administrative Agent, and upon such approval the Top-Up Amount Schedule shall be updated accordingly to reflect such change. A Project shall no longer be considered an Eligible Qualified Project or Qualified Project hereunder (and its project company shall no longer be a Project Company or Corresponding Project Company hereunder) if it no longer has Corresponding Term Loans hereunder. Any reallocation pursuant to this Section 5(z) shall not be considered a Transfer under Section 5(v).

(aa) Turbine Appraisal. Prior to each Top-Up Date, with respect to each Turbine for which Corresponding Term Loans have been made, the Administrative Agent may instruct the Independent Appraiser to prepare an appraisal of such Turbine (at the Borrower’s cost) in accordance with the Appraisal Procedure; provided, that no Turbine may be the subject of an appraisal more than once per calendar quarter under this Section 5(aa). The appraisal shall be the basis for determining the Appraised Value of such Turbine for all purposes of this Note. The Administrative Agent shall deliver a copy of the appraisal and notice of the Top-Up Amount to the Borrower no fewer than five (5) Business Days before such Top-Up Date.

(i) Except as permitted under this Note, any failure by the Borrower to have good title to all of its real property and good title to all of its personal property and assets, which failure would have a Material Adverse Effect on the Borrower’s ability to comply with its obligations under the Basic Documents to which it is party;

(j) The incurrence of any liability under any applicable environmental law which could reasonably be expected to have a Material Adverse Effect if such liability shall continue unremedied for a period of five (5) days after receipt of notice, or actual knowledge, thereof by the Borrower, or, if such liability cannot reasonably be remedied within such five (5) day period but is capable of being remedied as long as the Borrower is using diligent efforts to remedy such liability for a period of sixty (60) days after receipt of notice, or actual knowledge thereof, by the Borrower;

(k) A Change of Control shall occur and be continuing;

(1) Any permit required to be obtained or maintained by the Borrower under any Turbine Supply Documents shall be revoked or cancelled by the issuing governmental authority having jurisdiction, or any such permit shall otherwise fail to be in full force and effect, or the Borrower shall fail to comply with any such permit, in each case, which revocation, cancellation or failure would reasonably be expected to have a Material Adverse Effect, and in each case, if any adverse effect of such revocation, cancellation or failure is not remedied to the reasonable satisfaction of the Lenders within sixty (60) days after receipt of notice thereof by such Person;

(m) A final judgment or judgments shall be entered against the Borrower or any Corresponding Project Company, by a court of competent jurisdiction in an aggregate amount of not less than $150,000 other than (i) a judgment which is fully covered by a posted bond or discharged within thirty (30) days after its entry, or (ii) 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

(n) Any Turbine Supply Documents shall cease for any reason to be in full force and effect; or any default by the Borrower, any Corresponding Project Company or any Turbine supplier shall occur under any Turbine Supply Document (after giving effect to all applicable cure periods in such Turbine Supply Document) and such default would be reasonably likely to result in a Material Adverse Effect.

The Administrative Agent, each Lender and the Collateral Agent shall provide reasonable support for any costs, expenses and/or charges at the Borrower’s reasonable request and shall obtain approval from the Borrower (which shall not be unreasonably withheld or delayed) prior to incurring any unusual and extraordinary expenses. The foregoing amounts incurred in connection with the negotiation of this Note and the other Basic Documents may be funded with the Loans.

(b) The Borrower agrees to indemnify and hold the Administrative Agent, each Lender and the Collateral Agent together with its respective directors, officers, employees, agents and consultants harmless from and against all claims, damages, losses, liabilities, costs, deficiencies and documented expenses and damages, including, without limitation, investigative costs, settlement costs and reasonable legal, accounting or other expenses for investigating or defending against any actions or threatened actions (collectively, the “Losses”), arising out of or

The Administrative Agent, any Lender and/or the Collateral Agent, as applicable, shall promptly notify the Borrower of any claim under this Section 7(b). The Borrower 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 7(b); provided, however, that if the Borrower assumes control of the defense of any such action, proceeding or dispute, the Borrower shall not agree or conclude any settlement that affects the Administrative Agent, any Lender or the Collateral Agent without the prior written approval of the Administrative Agent, each Lender or the Collateral Agent, as applicable (such approval not to be unreasonably withheld). In the event the Borrower assumes control of the defense of any such action, proceeding or dispute, the Borrower shall not be liable to the Administrative Agent, any Lender or the Collateral Agent for any legal fees and expenses of additional counsel incurred by the Administrative Agent, any Lender or the Collateral Agent in connection with such defense; provided, however, that each of the Administrative Agent, the Lenders and the Collateral Agent shall have the right to employ its own counsel whose reasonable legal fees and expenses shall be indemnified by the Borrower if (A) there is or could reasonably be expected to be a conflict of interest between the Administrative Agent, any Lender or the Collateral Agent, as applicable, and the Borrower in connection with the defense of such action, proceeding or dispute, or (B) there is a specific defense available to the Administrative Agent, each Lender or the Collateral Agent, as applicable, which is different from or additional to those available to the Borrower, or (C) it is reasonably necessary to protect the interests of the Administrative Agent, each Lender or the Collateral Agent, as applicable, to the extent such interests differ from the interests of the Borrower.

(ii) Each Lender hereby appoints and authorizes the Collateral Agent to act as its agent hereunder and under the other Basic Documents with such powers as are expressly delegated to the Collateral Agent by the terms of this Note and the other Basic Documents, together with such other powers as are reasonably incidental thereto.

(b) Duties, Responsibilities, Powers and Immunities of Agents. The Agents shall not have any duties or obligations except those expressly set forth herein and in the other Basic Documents to which they are party. Without limiting the generality of the foregoing, (a) each Agent shall be subject to any fiduciary or other implied duties, regardless of whether an Event of Default has occurred and is continuing, (b) no Agent shall have any duty to take any discretionary action or exercise any discretionary powers, except discretionary rights and powers expressly contemplated hereby or by the other Basic Documents that each Agent is required to exercise in writing by the Majority Lenders or any other Agent, and (c) except as expressly set forth herein and in the other Basic Documents, no Agent shall have any duty to disclose, and shall not be liable for the failure to disclose, any information relating to First Wind Holdings or any of its subsidiaries that is communicated to or obtained by the Person serving as an Agent or any of its Affiliates in any capacity. No Agent shall be liable for any action taken or not taken by it in the absence of its own gross negligence or willful misconduct. No Agent shall be deemed to have knowledge of any Event of Default unless and until written notice thereof is given to such Agent by the Borrower, the Lenders or any other Agent. No Agent shall be responsible for or have any duty to ascertain or inquire into (i) any statement, warranty or representation made in or in connection with this Note or any other Basic Document, (ii) the contents of any certificate, report or other document delivered hereunder or thereunder or in connection herewith or therewith, (iii) the performance or observance of any of the covenants, agreements or other terms or conditions set forth herein or therein, (iv) the validity, enforceability, effectiveness or genuineness of this Note, any other Basic Document or any other

agreement, instrument or document, or (v) the satisfaction of any condition set forth herein or therein, other than to confirm receipt of items expressly required to be delivered to any Agent.

Each Agent shall be entitled to rely upon, and shall not incur any liability for relying upon, any notice, request, certificate, consent, statement, instrument, document or other writing believed by it in good faith to be genuine and to have been signed or sent by the proper Person. Each Agent may also rely upon any statement made to it orally or by telephone and believed by it in good faith to be made by the proper Person, and shall not incur any liability for relying thereon. Each Agent may consult with legal counsel, independent accountants and other experts selected by it, and shall not be liable for any action taken or not taken by it in accordance with the advice of any such counsel, accountants or experts.

Each Agent may resign at any time by notifying the Lenders, any other Agent, the Borrower and First Wind Holdings at least seven (7) days in advance. Any Agent may be removed involuntarily only for a material breach of its duties hereunder or under the other Basic Documents or for gross negligence or willful misconduct as determined by a final non-appealable judgment of a court of competent jurisdiction only upon the affirmative vote of the Majority Lenders (excluding such Agent from such vote and such Agent’s Loans and Commitments from the amounts used to determine the Majority Lenders). Upon any such resignation or removal, the Lenders shall have the right to appoint a successor, which successor shall (unless an Event of Default shall have occurred and be continuing) be subject to approval by the Borrower (such approval not to be unreasonably withheld, conditioned or delayed). The Agent’s resignation shall not be effective until a successor shall have been appointed by the Majority Lenders and shall have accepted such appointment. If no successor has accepted appointment as Agent by the date that is thirty (30) days following a retiring Agent’s notice of resignation, the retiring Agent’s resignation shall nevertheless thereupon become effective, and the Lenders shall assume and perform all of the duties of the Agent hereunder until such time, if any, as the Lenders appoint a successor Agent as provided for above. Upon the acceptance of its appointment as the Agent hereunder by a successor, such successor shall succeed to and become vested with all the rights, powers, privileges and duties of the retiring (or retired) Agent, and the retiring Agent, shall be discharged from its duties and obligations hereunder (if not already discharged therefrom as provided above in this paragraph). The fees payable by the Borrower to a successor Agent shall be the same as those payable to its predecessor unless otherwise agreed between the Borrower and such successor. After an Agent’s resignation hereunder, the provisions of this Section 11 shall continue in effect for its benefit in respect of any actions taken or omitted to be taken by it while it was acting as Agent.

Other than claims for fraud, willful misconduct or under express indemnities against any Person, the Administrative Agent and each Lender shall have no claims of any kind or nature with respect to the transactions contemplated by this Note and the other Basic Documents against any Affiliate of the Borrower that is not a Borrower Party or against any officer, member (other than a member that is a Borrower Party), director or employee, in such capacity, of the Borrower or any Affiliate of the Borrower, or any of its or their properties or assets.

(h) This Note and any agreement, document or instrument attached hereto or referred to herein integrate all the terms and conditions mentioned herein or incidental hereto and supersede all oral negotiations and prior writings with respect to the subject matter hereof.

(i) This Note may be executed in one or more facsimile counterparts, each of which shall be deemed to be an original, but all of which together will constitute one and the same agreement.

(j) The Administrative Agent, each Lender and the Collateral Agent agree to keep confidential, in accordance with its customary procedures for handling confidential information of this nature, any non-public information supplied to it by the Borrower in relation to the Turbine Supply Documents, the Governmental Approvals, the Borrower or First Wind Holdings; provided that such information does not include information that (i) was publicly known or otherwise known to it prior to the time of such disclosure and (ii) subsequently becomes publicly known through no act or omission by it or any Person acting on its behalf.

Schedule 2

Appraisal Procedure

A Fair Market Value (“FMV”) appraisal shall be performed by the Appraiser in accordance with the Appraisal Foundation’s Uniform Standards of Professional Appraisal Practice (“USPAP”) and subject to the Appraisal Procedure described below.

Appraisal Procedure

When requested by the Administrative Agent (but not more than once per calendar quarter), the Appraiser shall perform a FMV appraisal of the Turbines. Although the Appraiser must consider all three approaches to value (the Replacement Cost Approach, Sales Comparison Approach, and Income Capitalization Approach), as required and defined under USPAP, it is mutually acknowledged that the Income Capitalization Approach is not appropriate in this circumstance because the Turbines and the Corresponding Project Companies at no time constitute a cash flow-generating entity and since the wind turbine machinery comprising the Turbines consists entirely of uninstalled machinery and equipment that cannot be considered part of a “going concern” at the time of the Appraisal.

The value of the Turbines shall be determined as the lesser of the values produced by the Replacement Cost Approach and the Sales Comparison Approach, assuming, in both Approaches, payment in full and delivery of the Turbines.

In performing the Replacement Cost Approach, the Appraiser shall consider only turbines from manufacturers of comparable industry stature (“Comparable Manufacturers”) in assessing equipment of equivalent functional utility, with due consideration to capacity and future operational costs. In performing the Sales Comparison Approach, the Appraiser shall only consider equipment from Comparable Manufacturers. If, in the Appraiser’s judgment, insufficient data exist regarding recent transactions of equipment from Comparable Manufacturers, the Appraiser shall, in a manner consistent with formal appraisal procedure, adjust the sales comparison indicator of value to reflect differences between the transacted values of equipment from Comparable Manufacturers and transacted values of equipment from other manufacturers. The determination of Comparable Manufacturers shall be based on industry market share and installed base, degree and creditworthiness of warranty coverage, and the performance characteristics of the Equipment.

As part of the Reconciliation of Value Indications, the Appraiser shall report the Value of the Equipment as a single dollar value. Although a range of values may be referenced in the appraisal report, only the single dollar value reported as the Equipment’s Value shall be deemed the conclusion of the Appraisal. The single dollar value should represent the value of the most probable price within the range of values.
