(e) Notwithstanding anything set forth in this Section 6.17, (i) Seller shall not be liable to Buyer for indemnification under Section 6.17(a) (i) for any individual Claim where the Indemnifiable Losses resulting therefrom are less than $16,000 and (ii) unless the aggregate amount of all Indemnifiable Losses exceeds $82,000 (the “Threshold Amount”), in which event Seller shall only be liable for Indemnifiable Losses in excess of the Threshold Amount. (ii) In no event shall Seller’s liability to indemnify Buyer under Section 6.17(a)(i) through (iii) exceed the General Claims Escrow Amount (as may be reduced pursuant to Section 2.04(c)), and any Claim to be paid by Seller in accordance with Section 6.17(a)(i) through (iii) shall be paid solely from the General Claims Escrow Account. In no event shall Seller’s liability to indemnify Buyer under Section 6.17(a)(iv) with respect to any Development Project exceed the sum of (A) the Applicable Development Project Holdback Amount plus (B) the sum of all amounts required to be paid by Buyer or any of its Affiliates to G-I Energy Investments LLC in accordance with the terms of the Solar Energy (Fund III) Partnership II LLC Agreement in connection with any claim by G-I Energy Investments LLC thereunder for the failure of Development Project Substantial Completion to occur with respect to such Development Project. For the avoidance of doubt, recovery of Indemnifiable Losses pursuant to Section 6.17(a)(iv), subject to the limitations set forth in this Section 6.17, constitutes Buyer’s sole remedy for the failure of Seller to cause Development Project Substantial Completion to occur, whether prior to, at or following the Closing. (iii) The amount of any Indemnifiable Losses payable under this Section 6.17 shall be calculated net of any amounts actually recovered by Buyer or its applicable Affiliate under applicable insurance policies (including any representation and warranty insurance policy) or from any other Person responsible therefor, but shall be increased by any direct, reasonable and documented out-of-pocket expenses and any insurance premium increases solely to the extent directly attributable to any claim made in connection with the Indemnifiable Loss, in each case, to the extent incurred by such indemnified Person in collecting such amounts. In no event shall any Buyer Indemnified Person be required to pursue such recoveries. If the Buyer or its applicable Affiliate receives any amounts under applicable insurance policies, or from any other Person responsible for any Indemnifiable Losses, subsequent to an indemnification payment from Seller or from the General Claim Escrow Account or the Applicable Development Project Holdback Amount, then Buyer shall promptly reimburse Seller for any payment made or expense incurred by the indemnified Person in connection with providing such indemnification payment up to the amount received by such indemnified Person, net of any direct, out-of-pocket expenses, deductible and premium adjustments incurred by such indemnified Person in collecting such amount; (iv) Buyer shall not have any right to claim an Indemnifiable Loss pursuant to this Section 6.17 to the extent that such Indemnifiable Loss has been taken into account in the calculation of the Closing Adjustment Amount; and

58 (v) In no event shall Indemnifiable Losses include special, exemplary, punitive, consequential, incidental and indirect damages, lost profits (including damages on account of lost opportunities), lost production or losses based on diminution of value or calculated by reference to any multiple of earnings or earnings before tax, depreciation or amortization (or any other valuation methodology) except, in each case, to the extent that such losses or damages are the reasonably foreseeable result of the underlying event giving rise to such Indemnifiable Losses. (f) In connection with any Indemnifiable Loss for which Seller is required to indemnify Buyer hereunder, no less than five Business Days after such amount is agreed between Seller and Buyer or finally resolved by a court of competent jurisdiction, Buyer and Seller shall jointly instruct (i) the Escrow Agent, in accordance with the terms of the Escrow Agreement, to disburse to Buyer out of the General Claims Escrow Account an aggregate amount in cash equal to such Indemnifiable Losses subject to Section 6.17(e), by wire transfer of immediately available funds in U.S. Dollars to such account(s) specified by Buyer to the Escrow Agent in writing or (ii) Buyer to release out of the Applicable Development Project Holdback Amount (as applicable) an aggregate amount in cash equal to such Indemnifiable Losses subject to Section 6.17(e); provided that Seller shall not be obligated to execute and deliver to the Escrow Agent or Buyer any joint written instruction, and Buyer shall not be entitled to unilaterally execute and deliver any written instruction to the Escrow Agent or otherwise release any portion of the General Claims Escrow Amount or the Applicable Development Project Holdback Amount pursuant to this Section 6.17 if Seller in good faith disputes the Claim or the calculation of the Indemnifiable Losses. (g) Notwithstanding anything to the contrary herein, from and after the Closing, the Applicable Development Project Holdback Amount with respect to each Development Project shall be paid to Seller as follows: (i) On the Development Project First Release Date with respect to any Development Project, Buyer shall pay to Seller an amount equal to one-third of the Applicable Development Project Holdback Amount, minus the amount of any Claim made by Buyer in accordance with Section 6.17(a)(iv) and Section 6.17(b) and not previously paid from the General Claims Escrow Account or the Applicable Development Project Holdback Amount; and (ii) On the Development Project Final Release Date with respect to any Development Project, Buyer shall pay to Seller an amount equal to the remaining two-thirds of the Applicable Development Project Holdback Amount, minus the amount of any Claim made by Buyer in accordance with Section 6.17(a)(iv) and Section 6.17(b) (without duplication of any Claims for which amounts have already been taken into account in clause (i) above) and not previously paid from the General Claims Escrow Account or the Applicable Development Project Holdback Amount, minus any Development Project Capital Expenditures not taken into account in the Closing Adjustment Amount or otherwise paid by Seller or any of its Affiliates (without duplication of amounts subject to any Claim for which reductions have been taken into account in Section 6.17(g)(i) or this Section 6.17(g)(ii)). (iii) If, upon the full and final resolution of all Claims made by Xxxxx in accordance with Section 6.17(a) and Section 6.17(b), Buyer shall promptly (and no later than five Business Days after such determination) pay the remaining portion (if any) of the Development

70 other hand, of any of provision of this Agreement, Seller, on the one hand, and Buyer or Buyer Parent, on the other hand, shall be entitled to seek an injunction, specific performance and other equitable relief, and to enforce specifically the provisions of this Agreement, to prevent such non- performance or other breach or threatened breach of such provisions. Any Party seeking any injunction, specific performance or other equitable relief, or to enforce specifically the provisions of this Agreement, shall not be required to provide any bond or other security in connection with any such injunction, specific or other equitable relief or enforcement. In the event that any Proceeding is brought to enforce specifically the provisions of this Agreement, no Party shall allege, and each Party, on behalf of itself and its Affiliates and its and their respective Representatives, hereby waives the defense, that there is an adequate remedy at law and agrees that it will not oppose the granting of any equitable relief on the basis that (i) any Party has an adequate remedy at law or (ii) an award of specific performance is not an appropriate remedy for any reason at law or equity. Section 10.14 No Recourse. All causes of action or Proceedings (whether in contract or in tort, in equity or at Law, or granted by statute) that may be based upon, in respect of, arise under, out or by reason of, be connected with, or relate in any manner to this Agreement, or the negotiation, preparation, execution, delivery, performance or breach of this Agreement (including any representation or warranty made in, in connection with, or as an inducement to, this Agreement), may be brought only against (and are those solely of) the Persons that are expressly identified as parties to this Agreement (including Buyer Parent for the limited purposes set forth herein) in the preamble of this Agreement (each, a “Contracting Party”). No Person who is not a Contracting Party, including any past, present or future direct or indirect equity holder, Affiliate or Representative of such Contracting Party or any Affiliate or Representative of any of the foregoing (the “Non-Recourse Party”), shall have any Liability or other obligation (whether in contract or in tort, in equity or at Law, or granted by statute) for any cause of action or Proceeding arising under, out of, in connection with, or related in any manner to this Agreement or based on, in respect of, or by reason of this Agreement or its negotiation, preparation, execution, delivery, performance, or breach; and, to the maximum extent permitted by applicable Law, each Contracting Party hereby waives and releases all such causes of action and Proceedings against any such Non-Recourse Party. Without limiting the generality of the foregoing, to the maximum extent permitted by applicable Law, (a) each Contracting Party hereby waives and releases any and all causes of action or Proceedings that may otherwise be brought in equity or at Law, or granted by statute, to avoid or disregard the entity form of a Contracting Party or otherwise impose Liability or other obligation of any Contracting Party on any Non-Recourse Party, whether granted by statute or based on theories of equity, agency, control, instrumentality, alter ego, domination, sham, single business enterprise, piercing the veil, unfairness, undercapitalization, or otherwise; and (b) each Contracting Party disclaims any reliance upon any Non-Recourse Party with respect to the performance of this Agreement or any representation or warranty made in, in connection with, or as an inducement to this Agreement. Notwithstanding the foregoing, nothing in this Section 10.14 shall preclude any party to this Agreement, the Escrow Agreement, the Confidentiality Agreement or any other Transaction Document from making any claim thereunder, to the extent permitted therein and pursuant to the terms thereof (and subject to the applicable limitations set forth therein). Section 10.15 Release. Except for any rights under this Agreement or any other Transaction Documents, effective as of the Closing, each Party, on its own behalf and on behalf

71 of its direct and indirect equity holders, Affiliates and Representatives, and its and their respective Affiliates and Representatives, and each of the respective heirs, executors, administrators, successors and permitted assigns of each of the foregoing (each, a “Releasing Person”), hereby absolutely and unconditionally releases and forever discharges each of the other Parties, each of the Acquired Companies, each of their respective Affiliates, each of the respective successors and permitted assigns of each of the foregoing and the Representatives of each of the foregoing (each, a “Released Person”) from, and agrees not to assert any cause of action or Proceeding with respect to, any Losses or Liabilities whatsoever, of any kind or nature, whether at law or in equity (“Released Claims”), which have been or could have been asserted against any Released Person, which any Releasing Person has or ever had, which arises out of or in any way relates to events, circumstances or actions occurring, existing or taken prior to or as of the Closing Date in respect of matters relating to Seller’s ownership of the Company Interests or Seller’s ownership or operation of the Acquired Companies or their respective businesses. Section 10.16 Buyer Parent Guaranty. (a) As a material inducement to Seller’s willingness to enter into this Agreement and consummate the transactions contemplated hereby, Buyer Parent hereby absolutely, unconditionally and irrevocably guaranties to Seller as a primary obligation that Buyer shall fully, completely and timely pay, perform and discharge all of its obligations and Liabilities under this Agreement (the “Obligations”). Upon default by Buyer of any of the Obligations, Seller may proceed directly against Buyer Parent pursuant to the guaranty set forth in this Section 10.16 (the “Buyer Parent Guaranty”) without proceeding against Buyer or any other Person or pursuing any other remedy, and Buyer Parent shall, upon the written request of Seller (“Performance Demand”), immediately pay, perform and discharge such Obligations. A single Performance Demand shall be effective as to any specific default during the continuance of such default until Buyer or Buyer Parent shall have cured such default, and additional written demands concerning such default shall not be required until such default is cured. (b) This Buyer Parent Guaranty is a guaranty of payment and performance and not of collection. There are no conditions precedent to the enforcement of this Buyer Parent Guaranty. The obligations of Buyer Parent hereunder shall be continuing, absolute, unconditional and irrevocable and, without limiting the generality of the foregoing, shall not be released, discharged or otherwise affected by (i) any invalidity, illegality or unenforceability against Buyer of this Agreement or any other agreement or instrument delivered pursuant hereto; (ii) any modification, amendment, restatement, waiver or rescission of, or any consent to the departure from, any of the terms of this Agreement or any other agreement or instrument delivered pursuant hereto; (iii) any exercise or non-exercise by Seller of any right or privilege under this Agreement or any other agreement or instrument delivered pursuant hereto or any notice of such exercise or non-exercise; (iv) any extension, renewal, settlement, compromise, waiver or release in respect of any Obligation, by operation of law or otherwise, or any assignment of any Obligation by Seller; (v) any change in the corporate existence, structure or ownership of Buyer; (vi) any insolvency, bankruptcy, reorganization or other similar Proceeding affecting Buyer or Buyer’s assets or any resulting release or discharge of any Obligation; (vii) any requirement that Seller exhaust any right or remedy or take any action against Buyer or any other Person before seeking to enforce the obligations of Buyer Parent under this Buyer Parent Guaranty; (viii) the existence of any defense, set-off or other rights (other than a defense of payment, performance or discharge) that Buyer

72 Parent may have at any time against Buyer or any other Person, whether in connection herewith or any unrelated transactions; (ix) any other act or failure to act or delay of any kind by Buyer or any other Person; or (x) any other circumstance whatsoever that might, but for the provisions of this Buyer Parent Guaranty, constitute a legal or equitable discharge of the Obligations or the obligations of Buyer Parent hereunder, including all defenses of a surety. (c) This Buyer Parent Guaranty shall continue to be effective, or be automatically reinstated, as the case may be, if at any time payment or performance, or any part thereof, of any of the Obligations is rescinded or must otherwise be restored, returned or rejected by Seller for any reason, including upon the insolvency, bankruptcy, dissolution, liquidation or reorganization of Buyer, or upon or as a result of the appointment of a receiver, intervenor or conservator of, or trustee or similar officer for, Buyer or any substantial part of Buyer’s property, or otherwise, all as though such payments had not been made. Buyer Parent agrees that it will indemnify Seller on demand for all costs and expenses (including reasonable attorneys’ fees and disbursements) incurred by Seller in connection with such rescission or restoration, which amounts shall be in addition to all other obligations hereunder. If Seller is required to refund part or all of any payment of Buyer with respect to any of the Obligations, such payment shall not constitute a release of Buyer Parent from any Liability hereunder, and Buyer Parent’s Liability hereunder shall be reinstated to the fullest extent allowed under applicable Law and shall not be construed to be diminished in any manner. (d) If this Agreement is terminated pursuant to and in accordance with Section 9.01, then there shall be no Liability on the part of Buyer Parent in respect of this Agreement; provided that (a) the provisions set forth in this Section 10.16 shall remain in full force and effect in accordance with their terms and (b) such termination shall not relieve Buyer Parent from any Liability for any breach of this Agreement prior to such termination. Section 10.17 Conflict Waiver. Each of Seller and Buyer, on behalf of itself and its respective Affiliates (including, with respect to Buyer, the Acquired Companies following the Closing), acknowledges and agrees that, in connection with any dispute, Proceeding, Liability, obligation or other matter, including any dispute between Buyer, the Acquired Companies and/or any of its or their respective Affiliates, on the one hand, and Seller and/or any of its Affiliates, on the other hand, or with or between any other Persons, in each case solely with respect to the transactions contemplated by this Agreement, (a) as to all communications among Xxxxxxxx & Xxxxx LLP (“Seller’s Counsel”), the Acquired Companies, Seller and/or any of its Affiliates, the attorney-client privilege, attorney work product protection and the expectation of client confidence belongs solely to Seller and/or its Affiliates (other than the Acquired Companies), and may be controlled by Seller or its Affiliates (other than the Acquired Companies), and shall not pass to or be claimed by Buyer, the Acquired Companies, or any of its or their respective Affiliates and (b) Seller’s Counsel may disclose to Seller and/or its Affiliates any information learned by Seller’s Counsel in the course of its representation of Seller, the Acquired Companies or its or their respective Affiliates in the transactions contemplated by this Agreement, whether or not such information is subject to attorney-client privilege, attorney work product protection, of Seller’s Counsel’s duty of confidentiality. Accordingly, Buyer and its Affiliates shall not have or seek access to any such communications, or to the files of Seller’s Counsel related to the transactions contemplated by this Agreement, whether or not the Closing occurs. Without limiting the generality of the foregoing, upon and after the Closing, (i) to the extent that files of Seller’s

73 Counsel relate to the transactions contemplated by this Agreement and constitute property of the client, only Seller and its Affiliates shall hold such property rights and (ii) Seller’s Counsel shall have no duty whatsoever to reveal or disclose any such attorney-client communications or files to Buyer or the Acquired Companies by reason of any attorney-client relationship between Seller’s Counsel and any Acquired Company or otherwise. Section 10.18 Further Assurances. From time to time after the Closing, each Party shall execute and deliver, or cause to be executed and delivered, all such documents and instruments, and shall take, or cause to be taken, all such other actions as any other Party may reasonably request to evidence and effectuate the transactions contemplated by this Agreement.
