(c) a certificate of the secretary of each of the Purchasers, dated as of the Closing Date, certifying as to (i) the certificate of formation and operating agreement of each Purchaser, (ii) the resolutions of the manager of each Purchaser, authorizing the execution, delivery and performance of this Agreement and the consummation of the transactions

(e) all other previously undelivered items required to be delivered by the Purchasers to the Sellers at or prior to the Closing pursuant to this Agreement or otherwise required in connection herewith unless waived in writing by the Sellers.

(a) As soon as reasonably practicable following the Closing Date, and in any event within sixty (60) days thereof, the Purchasers shall prepare and deliver to the Principal Sellers a statement (the “Proposed Closing Statement”) setting forth a calculation of the Net Working Capital as of the Closing Date (“Closing Net Working Capital”) and the Company Indebtedness as of the Closing Date (“Closing Company Indebtedness”). For the avoidance of doubt, should the current employment contract between the Company and Andrew Hinckley not be terminated within seven (7) days after the Closing Date, then an amount equal to Andrew Hinckley’s base salary under such employment contract for a period of 30 days shall be included in Closing Company Indebtedness for purposes of the Proposed Closing Statement. The Proposed Closing Statement shall be prepared in a manner consistent with the Latest Balance Sheet and GAAP, which shall control as to any conflict as to the principles, practices, policies, judgments or methodologies to be applied in the preparation of the Proposed Closing Statement and the determination of the Closing Net Working Capital and the Closing Company Indebtedness.

(b) If the Principal Sellers shall disagree with the calculation of the Closing Net Working Capital and/or the Closing Company Indebtedness, the Principal Sellers shall notify the Purchasers of such disagreement in writing, setting forth in reasonable detail the particulars of such disagreement, within twenty (20) Business Days after receipt of the Proposed Closing Statement (an “Objection Notice”). If the Principal Sellers do not provide an Objection Notice within such period, the Principal Sellers shall be conclusively deemed to have accepted the Proposed Closing Statement and the calculation of the Closing Net Working Capital and the Closing Company Indebtedness delivered by the Purchasers, which shall be final, binding and conclusive for all purposes hereunder. If such notice of disagreement is timely provided, the Purchasers and the Principal Sellers shall seek in good faith for a period of fifteen (15) Business Days (or such longer period as they may mutually agree) to resolve any such disagreements. If, at the end of such period, they are unable to resolve such disagreements, then BDO USA, LLP (or such other independent accounting or financial consulting firm of recognized national standing as may be mutually selected by the Purchasers and the Principal Sellers) (the “Auditor”) shall resolve any remaining disagreements that were included in the Objection Notice. Each of the Purchasers and the Principal Sellers shall promptly submit to each other and the Auditor in writing their respective proposal for resolution of the dispute regarding the Closing Net Working Capital and/or the Closing Company Indebtedness. The Auditor shall establish the timing and

process of reviewing any disagreement and shall be instructed to provide its final determination with respect to any disagreement as soon as practicable and in any event within thirty (30) Business Days following the date on which the disagreement is referred to the Auditor; provided, however, that (i) the Auditor shall base its determination solely on the written submissions of the parties and shall not conduct an independent investigation and (ii) the Auditor shall have no authority to vary or ignore the terms of this Agreement. Each of the Purchasers and the Principal Sellers agrees to promptly make available to each other and to the Auditor all documents, books, records and personnel under that party’s control as the Auditor shall determine in its judgment to be necessary or relevant to its review of the disagreement and otherwise to cooperate with the other party and the Auditor to facilitate a prompt resolution of the disagreement. The determination of the Auditor shall be final, conclusive and binding on the Parties hereto. The date on which the Closing Net Working Capital and Closing Indebtedness are finally determined in accordance with this Section 2.6(b) (whether by the Principal Sellers’ failure to timely deliver an Objection Notice, by agreement of the Purchasers and the Principal Sellers or by the Auditor) is referred to as the “Determination Date.” The fees and expenses of the Auditor shall be borne by the Purchasers, on the one hand, and the Sellers, on the other hand, based upon the percentage which the aggregate portion of the contested amount not awarded to each party bears to the aggregate amount actually contested by such party. Following the Closing, the Purchasers shall provide the Principal Sellers and their Representatives reasonable access to the records, properties, personnel and (subject to the execution of customary work paper access letters, if requested) auditors of the Company during regular business hours relating to the Principal Sellers’ review of the Proposed Closing Statement and shall cause the personnel of the Purchasers and the Company to reasonably cooperate with the Principal Sellers in connection with their review of the Proposed Closing Statement.

(c) The “Adjustment Amount,” which may be positive or negative, shall mean (i) the Closing Net Working Capital (as finally determined in accordance with Section 2.6(b)) minus the Estimated Closing Net Working Capital used in calculating the Estimated Purchase Price in accordance with Section 2.2 (recognizing, for the avoidance of doubt, that the Estimated Closing Net Working Capital shall not exceed the Estimated NWC Cap), plus (ii) the Estimated Closing Company Indebtedness minus the Closing Company Indebtedness (as finally determined in accordance with Section 2.6(b)). The Adjustment Amount shall be paid in accordance with Section 2.6(d).

(d) If the Adjustment Amount is a positive number, the Purchasers shall pay the Adjustment Amount to the Sellers to the accounts set forth on Exhibit A, such payments to be distributed to each Seller based on such Seller’s Percentage Share as set forth on Exhibit A. If the Adjustment Amount is a negative number, the Sellers shall pay the Adjustment Amount to the Purchasers to an account designated by the Purchasers. All payments pursuant to this Section 2.6(d) shall be paid by wire transfer of immediately funds promptly following the Determination Date, and in any event within five (5) Business Days following the Determination Date. In the event Sellers owe a payment pursuant to this Section 2.6 and any Sellers fail to make such payment within ten (10) Business Days following the Determination Date, the Purchasers may deduct the amount of such payment from the Indemnification Escrow Amount. In the event the Purchasers owe a payment pursuant to this Section 2.6 and the Purchasers fail to make such payment within ten (10) Business Days following the Determination Date, Sellers may deduct the amount of such payment from the Indemnification Escrow Amount, and Purchasers shall thereafter promptly reimburse such amount by making a corresponding deposit to the Escrow Account.

(a) The Parties hereto acknowledge and agree the for U.S. federal income Tax purposes (and to the extent permitted for state and local income Tax purposes) (i) the Company shall terminate as a partnership within the meaning of Code Section 708(b)(1)(B) as of the end of the day on the Closing Date, (ii) the Sellers (other than the Blocker Seller) shall be treated as having sold their interests in the Company and shall report any gain or loss resulting therefrom in accordance with Section 741 of the Code, and the Blocker Seller shall be treated as having sold the Shares of the Blocker Corp and shall report any gain or loss resulting therefrom in accordance with Section 1001 of the Code, (iii) the Purchasers shall be treated as having purchased the Purchased Units and the Shares from the Sellers, and (iv) the Company shall continue in existence as a partnership and shall make (or has made) an election under Section 754 of the Code effective no later than the taxable year of the Company that includes the Closing Date.

(b) The purchase price (as determined for federal income Tax purposes) shall be allocated among the Shares and the Purchased Units and, to the extent allocated to the Purchased Units, the assets of the Company and the Subsidiaries consistent with Sections 751, 755 and 1060 of the Code and the Treasury Regulations promulgated thereunder, as set forth on Exhibit C hereto (the “Allocation”). The Allocation shall be binding on the Purchasers, the Company, the Blocker Corp., and the Sellers and their Affiliates for all income Tax and title insurance purposes, but not for purposes of GAAP financial statements or any disclosures related thereto. The Purchasers, the Company, the Blocker Corp and the Sellers and their Affiliates shall report, act, and file Tax Returns in all respects and for all income Tax purposes consistent with the Allocation and shall not take any position contrary thereto; provided, however that nothing contained herein shall be construed so as to require any party to commence or participate in any litigation or administrative process challenging any determination made by any Governmental Authority contrary to the Allocation.

6.8 Tax Dispute. The parties hereby agree to the terms set forth in Schedule 6.8.

6.9 Payment to Sellers Escrow Account. Sellers acknowledge and agree that all payments required to be made hereunder to the Sellers Escrow Account by Purchasers shall, if properly and timely made in accordance with the terms hereof, satisfy any requirement of payment to the Sellers, and that Purchasers shall not be responsible for the allocation or division of any such payment among Sellers once the payment to the Sellers Escrow Account has been properly and timely made.

7.1 Survival Representations, Warranties and Covenants. The representations and warranties of the Sellers, the Company and the Purchasers contained in Article III, Article IV and Article V, respectively, shall survive the Closing for a period of one (1) year after the Closing Date, except that the representations and warranties contained in Sections 3.1, 3.2, 3.3, 3.4, 3.5, 3.7, 4.1, 4.5, 4.10, 4.15(d), 4.22, 4.27, 5.1, 5.2, 5.3 and 5.7 shall expire upon the expiration of the applicable statute of limitations. The covenants which by their terms do not contemplate performance after the Closing shall terminate as of the Closing. The covenants which by their terms contemplate performance after the Closing shall survive the Closing in accordance with their respective terms.

(a) Indemnification of the Sellers. After the Closing, the Purchasers shall indemnify and hold harmless the Sellers (and their directors, managers, officers, employees, agents, Affiliates, successors, and assigns) from and against any and all Losses based upon, arising out of or incurred with respect to (i) any breach of any of the Purchasers’ representations and warranties contained in Article V or any certificate delivered at the Closing, (ii) any breach

or nonperformance of any covenant or obligation to be performed by the Purchasers hereunder (or the Company hereunder after the Closing) or under any agreement executed in connection herewith, or (iii) any matter arising out of the operation of the business of any of the Company or the Subsidiaries after the Closing to the extent not caused by or attributable to any act or omission of Sellers.

(b) Indemnification of the Purchasers. After the Closing, each Seller, severally (as described in Section 7.2(c)(vi)) and not jointly, shall indemnify and hold harmless the Purchasers (and its directors, managers, officers, employees, agents, Affiliates, successors, and assigns) (the “Purchasers Indemnitees”) from and against any and all Losses based upon, arising out of or incurred with respect to (i) any breach of such Seller’s representations and warranties in Article III or any certificate delivered at Closing, (ii) any breach or nonperformance of any covenant or obligation to be performed by such Seller hereunder or under any agreement executed in connection herewith, (iii) any breach of the Seller’s representations and warranties regarding the Company and the Subsidiaries in Article IV of this Agreement or (iv) the Operating Wind Project Liabilities. For the avoidance of doubt, (A) the Blocker Seller shall be solely liable for any indemnification obligation arising from a breach of a representation or covenant pertaining to the Blocker Corp or the Shares, including the representations set forth in Section 3.5 and (B) in no event shall the Purchasers, collectively, be entitled to double recovery for the same Loss. Any indemnification obligation arising from a breach of Section 4.10(h) shall be borne solely by the Seller(s) to whom the applicable Foreign Partner Withholding Tax is attributable.

(c) Limitations on Indemnification Obligations. The rights of the Purchasers Indemnitees to indemnification pursuant to the provisions of Section 7.2(b) are subject to the following limitations:

(i) the amount of any Loss subject to indemnification hereunder or of any Claim therefor shall be calculated net of any insurance proceeds (net of direct collection expenses) or other collateral sources (such as contractual indemnities of any Person which are contained outside of this Agreement), received by the Purchasers Indemnitees on account of such Loss. The Purchasers Indemnitees shall seek full recovery under all insurance policies covering any Loss or collateral sources to the same extent as they would if such Loss were not subject to indemnification hereunder and the Purchasers, the Company and the Subsidiaries shall not cancel any insurance policies in effect for periods prior to the Closing. In the event that an insurance recovery or indemnification payment is received by the Purchasers Indemnitees with respect to any Loss for which any such Person has been indemnified hereunder, then a refund equal to the aggregate amount of the recovery or payment (net of direct collection expenses and Taxes) shall be made promptly to the Sellers, which refund shall be distributed based on the proportion of the Loss borne by each such Seller, or, if a Loss has not yet been determined or paid by the Sellers, the Sellers’ indemnification obligations in respect of such Loss shall be reduced by the aggregate amount of the insurance recovery or indemnification payment (net of direct collection expenses);

(ii) no adjustment shall be made as a result of any multiple, increase factor, or any other premium over the value paid by the Purchasers at Closing whether or not such multiple, increase factor or other premium had been used by Purchasers at the time of, or in connection with, calculating or preparing its bid, its proposed purchase price for the Purchased Units and the Shares or its final purchase price for the Purchased Units and the Shares;

(iii) except for Claims arising under Section 3.5 or in respect of Operating Wind Project Liabilities, the Purchasers Indemnitees will not be entitled to recover the first $200,000 in aggregate Losses (as limited by the applicable provisions of this Section 7.2(c) pursuant to Section 7.2(b), which amount shall serve as a one-time deductible against Losses; provided, however, that thereafter solely with respect to Losses that are individually less than $50,000 the Purchasers Indemnitees will not be entitled to recover for such Losses pursuant to Section 7.2(b) until such Losses that are individually less than $50,000 are equal to or exceed $300,000 in the aggregate (and then only to the extent of such excess);

(iv) except for Claims arising under Sections 3.1, 3.2, 3.3, 3.4, 3.5, 3.7, 4.1, 4.5, 4.10, 4.15(d), 4.22, 4.27 and in respect of Operating Wind Project Liabilities (in which case the Sellers’ aggregate liability hereunder for all such Losses will not be permitted to exceed the Purchase Price), the Purchasers Indemnitees will not be entitled to recover Losses pursuant to Section 7.2(b) to the extent the Sellers aggregate liability hereunder for all such Losses would otherwise exceed twenty percent (20%) of the Purchase Price (as adjusted pursuant to Section 2.6) if the Claim pertains to Section 4.11, 4.12, 4.15, 4.16, 4.17, 4.23, 4.25, or 4.26 and ten percent (10%) of the Purchase Price for all other items not listed in the immediately preceding clause or in the lead-in qualifier to this subsection (the “Liability Cap”) in the aggregate, and each Seller’s liability for Losses hereunder shall not exceed its Percentage Share of the Liability Cap;

(v) except for Claims arising under Section 3.5, the Purchasers Indemnitees shall not be entitled to recover Losses pursuant to Section 7.2(b) if (A) the Purchasers (or any director or officer of Purchasers who is not a Seller or a director, officer or consultant of the Company prior to Closing) had actual knowledge at any time on or prior to the Closing Date of the facts, events or conditions constituting or resulting in such breach of representation, warranty or covenant or (B) the Purchasers could have mitigated or prevented such Loss using commercially reasonable efforts; and

(vi) except for Claims arising under Section 3.5, with respect to a particular Loss, each Seller shall only be required to indemnify the Purchasers Indemnitees up to the amount of such Loss multiplied by such Seller’s Percentage Share. The Purchasers, for themselves and for the Purchasers Indemnitees, unconditionally waives any right it or they may have to hold any Seller jointly liable for the obligations of any other Seller. The aggregate liability of any Seller under this Section 7.2 shall not exceed such Seller’s Percentage Share of the Purchase Price (as adjusted pursuant to Section 2.6) for the Purchased Units and the Shares sold by such Seller to the Purchasers hereunder.

(d) Additional Indemnity Provisions. The indemnification obligations of the Purchasers and the Sellers hereunder shall be subject to the following terms and conditions:

(i) Except for Claims (A) against the Sellers arising under this Agreement, the Purchasers shall not assert and shall cause the Company, the Subsidiaries, the Blocker Corp and their Affiliates not to assert any Claims against any present or former

manager, officer, employee, or agent of the Sellers or against the Sellers, for or with respect to any matter relating to the Sellers prior to Closing, and (B) against the Purchasers arising under this Agreement, the Sellers shall not assert and shall cause their Affiliates not to assert any Claims against any present or former director, manager, officer, employee or agent of the Purchasers, the Company or the Subsidiaries or their Affiliates or against the Purchasers, the Company or the Subsidiaries, or their Affiliates, for or with respect to any matter relating to the Company or the Subsidiaries prior to the Closing.

(ii) The sole recourse and exclusive remedy of the Purchasers and the Sellers against each other arising out of this Agreement or any certificate delivered in connection with this Agreement, or otherwise arising from the Purchasers’ acquisition of the Purchased Units and the Shares, shall be to assert a Claim for indemnification under the indemnification provisions of Sections 7.2(a), and 7.2(b).

(iii) Without limiting the generality or effect of Section 7.2(d)(ii), as a material inducement to the other Parties hereto entering into this Agreement, each Party to this Agreement hereby (A) waives, and forever releases and discharges the other Parties and their respective Representatives from, by reason of or relating to the execution and delivery of this Agreement and the transactions contemplated hereby, any Claim which it otherwise might assert (except for fraud), including without limitation under the common law or federal or state securities, trade regulation, environmental or other Laws, except for Claims or causes of action for which contractual indemnification may be sought under, and subject to the express terms and conditions of, Sections 6.3(b) and this Section 7.2, (B) agrees not to, and to cause its and Representatives not to, directly or indirectly, institute, prosecute or aid in the prosecution of any Claim or other proceeding against any other Party or Representative thereof, which is the subject of clause (A) of this Section 7.2(d)(iii), and (C) agrees that, regardless of the foregoing provisions, no Party will have any liability or obligation in respect of any Claim or cause of action that is or may be brought except in respect of Losses, and then only to the extent expressly provided in this Section 7.2.

(iv) For the purposes of determining whether there has been a breach or an inaccuracy in respect of any representation or warranty for the purpose of indemnification under this Section 7.2, all Claims for Losses arising out of the same facts, events or circumstances resulting in such inaccuracy or breach shall be treated as a single Claim.

(v) To the extent that an Indemnifying Party has discharged any Claim for indemnification hereunder, the Indemnifying Party shall be subrogated to all rights of the Indemnified Party against any Person to the extent of the Losses that relate to such Claim. Any Indemnified Party shall, upon written request by the Indemnifying Party following the discharge of such Claim, execute an instrument reasonably necessary to evidence such subrogation rights.

(vi) In the event that any Party to this Agreement proposes to make any Claim for indemnification pursuant to this Section 7.2, or would have the right to make a Claim for indemnification but for the minimum or maximum limitations on indemnification contained in Section 7.2(b), the Party making the Claim (or with such right) (the “Indemnified Party”) shall promptly deliver on or prior to the date upon which the applicable representations and warranties or covenants expire pursuant to the terms of this Agreement and within a reasonable

time of discovery of the breach of or nonperformance of any covenant or obligation to be performed under this Agreement, a certificate signed by the party making the Claim or an officer of the party making the Claim (the “Claim Certificate”) to the Sellers or the Purchasers, whichever is applicable (such party from whom indemnification is sought the “Indemnifying Party”), which Claim Certificate shall (A) state the occurrence giving rise to the Claim and that the Loss or liability has been properly accrued or is anticipated; (B) specify the section of this Agreement under which such Claim is made; and (C) specify in reasonable detail each individual item of Loss or other Claim, including the section of this Agreement under which such Claim is made, the amount thereof if reasonably ascertainable, the date such Loss or liability was incurred, properly accrued or is anticipated, the basis for any anticipated Loss or liability and the nature of the misrepresentation, breach of warranty or the Claim to which such Loss or liability is related. The Indemnified Party making the Claim shall state only what is required in subsections (A)-(C) above and shall not admit or deny the validity of the facts or circumstances out of which such Claim arose.

(vii) Any payments made as indemnification under Sections 7.2(a) or 7.2(b) shall be treated as an adjustment to the Purchase Price for all income Tax purposes, unless otherwise required by Law.

(viii) the obligations to indemnify and hold harmless pursuant to Section 7.2(a) and Section 7.2(b) shall survive the Closing for the periods set forth in Section 7.1, except for Claims for indemnification pursuant to such sections asserted prior to the end of such periods, which Claims shall survive until the final resolution thereof.

(ix) WITHOUT LIMITING THE FOREGOING, THE PURCHASERS SHALL NOT BE ENTITLED TO INDEMNIFICATION UNDER THIS SECTION 7.2 WITH RESPECT TO INCIDENTAL DAMAGES, SPECIAL DAMAGES, EXEMPLARY DAMAGES, CONSEQUENTIAL DAMAGES, INCLUDING CONSEQUENTIAL DAMAGES CONSISTING OF BUSINESS INTERRUPTION, LOST PROFITS OR PUNITIVE DAMAGES.

(i) Subject to the Purchasers’ obligations under Section 7.2(c)(i), the Indemnifying Party shall have the right, in its discretion and at its expense, to participate in and control (A) the defense or settlement of any Claim (including appeals) (a “Third Party Claim”) in respect of such item (or items) by any Person other than the Indemnified Party, subject to the prior written consent of the Indemnified Party with respect to any non-monetary provisions of any settlement (which consent shall not be unreasonably withheld, conditioned or delayed), (B) any and all negotiations with respect thereof, and (C) the assertion of any claim against any insurer with respect thereto. Notwithstanding the foregoing, Indemnifying Party’s right to control any settlement or litigation (excluding any settlement or litigation associated with the Tax Dispute, which shall be governed by Schedule 6.8) is further subject to the following: (x) in the event that the Claim is being made by a third party who is a counterparty to any Material Contract, then Purchasers shall have the right to participate in the defense of such Claim, including by retaining legal counsel (at their sole cost and expense) and consulting with the Indemnifying Party, although the Indemnifying Party shall ultimately control the defense of such

Claim (which control and defense of the Claim shall be exercised in a reasonable manner); and (y) the Indemnifying Party shall only settle claims with the prior written consent of Purchasers (which consent shall not be unreasonably withheld, conditioned or delayed). Upon the Indemnifying Party’s payment of any amounts due in respect of such Third Party Claim, the Indemnified Party will, to the extent of such payment, assign or cause to be assigned to the Indemnifying Party the claims of the Indemnified Party, if any, against such third parties in respect of which such payment is made.

(f) Disclosure Generally. If and to the extent any information required to be furnished in any Schedule is contained in this Agreement or in any other Schedule attached hereto (or in any Schedules Supplement), such information shall be deemed to be included in all Schedules in which the information is required to be included to the extent such disclosure is reasonably apparent on its face. The inclusion of any information in any Schedule attached hereto (or in any Schedules Supplement) shall not be deemed to be an admission or acknowledgement by the Sellers or the Company, in and of itself, that such information is material to or outside the ordinary course of the business of the Company or any of the Subsidiaries.

7.3 Escrow Amount. In order to secure Sellers’ indemnity as provided in this Article VII, on the Closing Date, the Principal Sellers and the Purchasers shall enter into the Escrow Agreement with the Escrow Agent. Six (6) months after the Closing Date, the Principal Sellers shall instruct the Escrow Agent to return to Sellers an amount equal to fifty percent (50%) of the portion of Indemnification Escrow Amount pertaining to the deposit of ten percent (10%) of the Estimated Purchase Price, less the amount of any Claims made by Purchasers under this Article VII. On the first anniversary of the Closing Date, the Principal Sellers shall instruct the Escrow Agent to return to Sellers the balance of the portion of the Indemnification Escrow Amount pertaining to the deposit of ten percent (10%) of the Estimated Purchase Price shall be returned to the Sellers, less the amount of any unpaid Claims made by Purchasers under this Article VII. In the event that one (1) year after the Closing Date there are any unresolved Claims for indemnification made by Purchasers under this Article VII, subject to the continued withholding of a portion of the Indemnification Escrow Amount pursuant to the terms of Schedule 6.8, the balance of the Indemnification Escrow Amount not needed to pay such Claims shall be distributed to the Sellers Escrow Account for the account of the Sellers and such amounts needed to pay such Claims shall remain in the Escrow Account and shall be distributed to the Sellers Escrow Account for the account of the Sellers if and to the extent that such Claims against the Sellers are resolved and such amount is not needed to pay such Claims. The Escrow Agent shall comply with all requests from the Principal Sellers so long as the Escrow Agent receives no objection from Purchasers, in writing, within five (5) days after such request. Notwithstanding the foregoing, the release of the Additional Escrow Amounts shall be governed by Section 6.1 and Section 6.8 and the terms of the Escrow Agreement. Upon the receipt of funds in the Sellers Escrow Account, the Principal Sellers shall promptly instruct the Escrow Agent to distribute such funds to the Sellers based on the terms of the Company Operating Agreement (as if it were in effect at the time of such distribution).

(a) Unless this Agreement specifically requires otherwise, any notice, demand or request provided for in this Agreement, or served, given or made in connection with it, shall be in writing and shall be deemed properly served, given or made if delivered in person or sent by facsimile or email or sent by registered or certified mail, postage prepaid, or by an internationally recognized overnight courier service that provides a receipt of delivery, in each case, to the Parties at the addresses specified below:

(b) Effective Time. Notice given by personal delivery, mail or overnight courier pursuant to this Section 8.1 shall be effective upon physical receipt. Notice given by facsimile pursuant to this Section 8.1 shall be effective as of (i) the date of confirmed delivery if delivered before 5:00 p.m. Eastern Time on any Business Day or (ii) the next succeeding Business Day if confirmed delivery is after 5:00 p.m. Eastern Time on any Business Day or during any non-Business Day.

8.2 Entire Agreement. This Agreement and the Confidentiality Agreement supersedes all prior discussions and agreements between the Parties with respect to the subject matter hereof and contains the sole and entire agreement between the Parties with respect to the subject matter hereof.

8.3 Expenses. Except as otherwise expressly provided in this Agreement, whether or not the transactions contemplated hereby are consummated, each Party will pay its own costs and expenses incurred in connection with the negotiation, execution and closing of this Agreement and the transactions contemplated hereby.

8.4 Public Announcements. No public announcement (whether in the form of a press release or otherwise) shall be made by or on behalf of any Party or its Representatives with respect to the subject matter of this Agreement unless: (a) the other Party has agreed in writing to permit such public announcement to be made, which permission shall not be unreasonably withheld, or (b) such public announcement is required by Law and the Party required to make such announcement has given prior written notice in accordance with Section 8.1 to the other Party as promptly as practicable prior to such announcement. Any public announcement made as permitted under this Section 8.4 shall be made only in accordance with a text mutually agreed upon by the Parties, which agreement shall not be unreasonably withheld or delayed.

8.5 Waiver. Any term or condition of this Agreement may be waived at any time by the Party that is entitled to the benefit thereof, but no such waiver shall be effective unless set forth in a written instrument duly executed by or on behalf of the Party waiving such term or condition. No waiver by any Party of any term or condition of this Agreement, in any one or more instances, shall be deemed to be or construed as a waiver of the same or any other term or condition of this Agreement on any future occasion. All remedies, either under this Agreement or by Law or otherwise afforded, will be cumulative and not alternative.

8.6 Amendment. This Agreement may be amended, supplemented or modified only by a written instrument duly executed by or on behalf of each Party.

8.7 No Third Party Beneficiary. The terms and provisions of this Agreement are intended solely for the benefit of each Party and their respective successors or permitted assigns, and it is not the intention of the Parties to confer third-party beneficiary rights upon any other Person, except as set forth in Sections 6.3(b), 7.2(a), and 7.2(b).

8.8 No Assignment; Binding Effect. Neither this Agreement nor any right, interest or obligation hereunder may be assigned by any Party without the prior written consent of the other Parties, and any attempt to do so will be void, except for assignments and transfers by operation of Law. Subject to the preceding sentence, this Agreement is binding upon, inures to the benefit of and is enforceable by the Parties and their respective successors and assigns.

8.9 Headings. The headings used in this Agreement have been inserted for convenience of reference only and do not define or limit the provisions hereof.

8.10 Invalid Provisions. If any provisions of this Agreement is held to be illegal, invalid or unenforceable under any present or future Law, and if the rights or obligations of any Party under this Agreement will not be materially and adversely affected thereby, (a) such provision will be fully severable, (b) this Agreement will be construed and enforced as if such illegal, invalid or unenforceable provision had never comprised a part hereof, (c) the remaining provisions of this Agreement will remain in full force and effect and will not be affected by the illegal, invalid or unenforceable provision or by its severance herefrom, and (d) in lieu of such illegal, invalid or unenforceable provision, there will be added automatically as a part of this Agreement a legal, valid and enforceable provision as similar in terms to such illegal, invalid or unenforceable provision as may be possible.

8.11 Governing Law. This Agreement shall be governed by and construed in accordance with the Laws of the State of New York, without regard to any conflict of laws provisions thereof that would result in the application of the Laws of another Jurisdiction.

8.12 Jurisdiction and Venue. Each of the Parties hereby irrevocably and unconditionally submits, for itself and its property, to the non-exclusive jurisdiction of the Supreme Court of the State of New York sitting in the Borough of Manhattan and of the United States District Court for the Southern District of New York, and any appellate court from any such court, in any action or proceeding arising out of or relating to this Agreement. Each of the Parties waives any defense of inconvenient forum to the maintenance of any action or proceeding so brought and waives any bond, surety or other security that might be required of any other Party with respect thereto. Each Party agrees that service of summons and complaint or any other process that might be served in any action or proceeding may be made on such Party by sending or delivering a copy of the process to the Party to be served at the address of the party and in the manner provided for the giving of notices in Section 8.1. Nothing in this Section 8.12, however, shall affect the right of any Party to serve legal process in any other manner permitted by Law. Each Party agrees that a final, non-appealable judgment in any action or proceeding so brought shall be conclusive and may be enforced by suit on the judgment or in any other manner provided by Law.

8.13 Waiver Of Jury Trial. EACH OF THE PARTIES HERETO WAIVES ANY RIGHT IT MAY HAVE TO TRIAL BY JURY IN RESPECT OF ANY CLAIM BASED ON, ARISING OUT OF, UNDER OR IN CONNECTION WITH THIS AGREEMENT OR ANY COURSE OF CONDUCT, COURSE OF DEALING, VERBAL OR WRITTEN STATEMENT OR ACTION OF ANY PARTY HERETO.

8.14 Specific Performance. The Parties acknowledge that the rights of each Party to consummate the transactions contemplated hereby are unique and recognize and affirm that in the event of a breach of this Agreement by any Party, money damages may be inadequate and the non-breaching Party may have no adequate remedy at law. Accordingly, the Parties agree that such non-breaching Party or Parties shall have the right, in addition to any other rights and remedies existing in their favor at law or in equity, to enforce their rights and the other Party’s obligations hereunder not only by an action or actions for damages but also by an action or actions for specific performance, injunctive and/or other equitable relief (without posting of bond or other security).

8.15 Counterparts. This Agreement may be executed in any number of counterparts, each of which will be deemed an original, but all of which together will constitute one and the same instrument.

8.16 Time of Essence. Time is of the essence in this Agreement. If the date specified in this Agreement for giving any notice or taking any action is not a Business Day (or if the period during which any notice is required to be given or any action taken expires on a date which is not a Business Day), then the date for giving such notice or taking such action (and the expiration date of such period during which notice is required to be given or action taken) shall be the next day which is a Business Day.

IN WITNESS WHEREOF, the Parties hereto have caused this Agreement to be duly executed as of the date first above written.
