(d) At the Closing with respect to the Hawaii Oahu Group or the Hawaii Kawailoa Group, each Buyer shall reimburse Seller Parent (or its designee) for its pro rata share of all third-party, documented bona fide development and construction expenses (excluding legal and advisory fees and expenses, which shall be the responsibility of Sellers) incurred by Seller Parent and its Affiliates with respect to the Oahu Company Group or the Kawailoa Company Group, as applicable, on arm’s length terms between the date of this Agreement and such Closing (i) in the ordinary course of business, consistent with past practice and, with respect to any expense or series of related expenses, not in excess of $100,000 (ii) set forth on Schedule 6.16(d) or (iii) otherwise expressly approved in writing to be reimbursed by Buyers, provided that Seller Parent shall have provided to Buyers at least three (3) Business Days prior to such Closing an accounting of such expenses and reasonable evidence thereof, and provided, further, for clarity, the payment to HECO referenced in Section 6.16(c) shall not be reimbursed.

(e) Seller Parent shall, and shall cause each applicable Seller, each applicable Company, and each Subsidiary of each applicable Company to, use reasonable efforts to assist and cooperate with Buyers with respect to the timely issuance of the full notice to proceed with respect to each Project of the Hawaii Group.

(a) To the extent that a Project owned by Four Brothers Company, Granite Mountain Company, Iron Springs Company or any of their respective Subsidiaries (each, a “Cost Adjustment Project”) achieves commercial operation (as defined in the relevant debt financing documents with respect to such Project) and realizes an actual cash cost savings on the construction of such Cost Adjustment Project relative to the applicable Base Case Model (as defined in the limited liability company agreement of the applicable Company) (the “Original Model”), which shall be updated at each applicable Cost Adjustment Project commercial operation date solely for actual cash construction costs in accordance with Section 1 of Schedule 3.4 to each such limited liability company agreement (the “Updated Model”) (with respect to such Cost Adjustment Project, the amount equal to (x) the positive difference between the sum of the capital contribution of Dominion Solar Projects III, Inc. (as calculated in the Updated Model) and the Term Loan Commitment (as defined in the applicable financing agreement related to the applicable Project as in effect as of the date hereof) less the total project costs set forth on the Updated Model, less (y) any costs required to calculate the amounts including third party reports, lender waiver, counsel fees and up-front fee to existing lender, if still in the project, less (z) any additional capital contributions made to the applicable Company and its Subsidiaries after the Closing that are applied towards project costs with respect to such Company, and calculated consistent with the principles described in the last sentence of this Section 6.18(a), the “Cost Savings”). Buyers shall exercise their rights under the organizational documents of the applicable Companies to cause (to the extent of such rights) the applicable Companies and their Subsidiaries to make a distribution to the Buyers and the other members of the applicable Project

Company in an amount equal to such Cost Savings on the applicable commercial operation date or thereafter, subject to receiving project lender approval, and shall pay the amount of the Buyers’ share of such distributions actually received by Buyers (net of any Taxes) to Seller Parent (or its designee) subject to the terms and conditions set forth below. For the avoidance of doubt, the calculation of Cost Savings pursuant to this Section 6.18 shall be completed only with respect to Section 1 of the applicable Schedule 3.4 referred to in this Section 6.18(a) , and excluding, any such section that accounts for test energy revenue or any additional applicable revenue received by the project including interconnect reimbursement.

(b) This Section 6.18 shall only apply to a project with respect to which the Closing has occurred.

(c) With respect to any Cost Savings for a Cost Adjustment Project, Buyers shall not be required to pay to Seller Parent any amount in excess of the lesser of (i) the amount of remaining proceeds from equity or debt financing sources under the applicable financing agreement as in effect as of the date hereof related to the applicable Project (for the avoidance of doubt excluding any revenue) as of the commercial operation date that are available for and permitted to be distributed from the applicable Project Company to Buyer in accordance with all applicable financing documents, the organizational documents of the applicable Company and its Subsidiaries (including the applicable Project Subsidiary) and Applicable Law, and (ii) the Buyers’ share, in accordance with the applicable organizational documents of the Project Company, of the actual Cost Savings with respect to such Cost Adjustment Project (as calculated in accordance with Section 6.18(a)).

(d) Any amount distributed to Buyers in accordance with this Section 6.18 shall be payable to Seller Parent as follows, in each case, subject to Section 6.18(e)):

(i) 75% of such distributed amount within 10 Business Days after the receipt of the applicable distribution by Buyers, subject to lender approval; and

(ii) the remaining 25% of such distributed amount within 180 days after the applicable commercial operation date, provided that if actual total project costs for the applicable Project set forth in the Updated Model for such Project exceeds the total project cost as set forth in the Original Model for such Project (a “Cost Overrun”), Buyers may retain an amount up to such Cost Overrun (less any amount previously reimbursed to Buyers pursuant to last sentence of this Section 6.18(d)) as reimbursement. If the amount of Cost Overrun with respect to any Project subject to this Section 6.18 exceeds the total project cost as set forth in the Original Model for such Project , Seller Parent shall reimburse an amount equal to such Cost Overrun to Buyers within 10 Business Days from receipt of notice from Buyers with respect to such Cost Overrun after final completion of the applicable Project.

For the avoidance of doubt, notwithstanding anything to the contrary in this Section 6.18, any Cost Savings and/or Cost Overrun calculations contemplated by this Section 6.18 shall be calculated based on the debt financing sources under the financing agreements for the applicable Cost Adjustment Project as in effect as of the date hereof (and shall not take into account any debt financing that has been amended, replaced or otherwise refinanced at the time of the calculation of such Cost Savings and/or Cost Overrun calculations).

(e) Each of the Buyers, the Seller Parent and Sellers shall cooperate and use good faith efforts to replace the Granite Mountain LC and the Iron Spring LC on or prior to applicable Closing with letters of credit substantially similar to the Granite Mountain LC and the Iron Spring LC (as applicable) that would not require cash collateralization upon the applicable Closing and on substantially the same terms for the provision thereof (including, without limitation, at substantially the same cost and expense for the issuance and maintenance of the Granite Mountain LC and the Iron Spring LC) (collectively, the “Replacement LCs”). If the Buyers, the Seller Parent and Sellers secure such Replacement LCs, such Replacement LCs shall remain in place and effective until the commercial operation date of the Project owned by the Granite Mountain Company and the Project owned by the Iron Springs Company or any of their respective Subsidiaries. For the avoidance of doubt, under no circumstances shall Buyers, any of their Affiliates, or any of their direct or indirect equityholders be required to post a guarantee in order to replace the Granite Mountain and/or the Iron Spring LC.

(f) (i) Each payment that would be otherwise payable to Seller Parent pursuant to clause (d) above shall be reduced (but not below zero) by the amount of the outstanding Credit Support Cost Recapture Amount. “Credit Support Recapture Amount” means (A) $3,000,000 plus (B) any upfront costs of securing any Replacement LC in accordance with Section 6.18(e).

(ii) Solely in the event that the Replacement LCs are not secured and if the obligations secured by the Granite Mountain LC and/or the Iron Springs LC are required to be cash collateralized in connection with the Closing with respect to the Three Cedars Group in accordance with financing agreement as in effect as of the date hereof for the Three Cedars Group and/or any of its Subsidiaries, then: (x) to the extent that any amounts are then due and payable to Seller Parent pursuant to Section 6.18(d), such amount shall be directed by Buyers to satisfy such cash collateral obligations to the extent of such amount that is due and payable and the Buyers shall be permitted to set off the cash collateral amounts posted by the Buyers under this Section 6.18(f) against the payments that would otherwise be payable to Seller under Section 6.18(d) and (y) to the extent that no or insufficient amounts are then due and payable to Seller Parent pursuant to Section 6.18(d), such cash collateral obligations shall be the responsibility of Sellers or Seller Parent (and Sellers and Seller Parent shall promptly deposit such cash collateral as and when required).

(iii) On or prior to October 31, 2019, upon the release to Buyers of all or any portion of the cash collateral provided by Buyers in accordance with clause (ii) above, Buyers shall pay an amount equal to (A) such portion of the released cash collateral that is actually received by Buyers and in respect of which the Buyers have exercised their set off rights under clause (ii) above, less the Credit Support Recapture Amount outstanding as of such date.

(g) If any distribution contemplated by this Section 6.18 that would be permitted under Applicable Law and the organizational documents of the applicable Project

Company but required consent of any project lenders, the Buyers shall seek in good faith to obtain such consent, and any such distribution shall only be required to be made upon approval by the lenders.

(h) As soon as reasonably practicable after the commencement of commercial operation of each Cost Adjustment Project, Buyer shall deliver to Seller Parent a written determination (each, a “Cost Savings Determination”) of the Cost Savings with respect to such Cost Adjustment Project, in each case including the basis for such Determination set forth in reasonable detail and all supporting calculations.

(i) Upon receipt of each Cost Savings Determination, Seller Parent shall have thirty (30) days (the “Review Period”) to review such Cost Savings Determination. In connection with the review of such Cost Savings Determination, Buyer shall cause (to the extent of Buyers rights with respect to such entities) the applicable Companies and the Companies’ Subsidiaries to give, to Seller Parent and its Representatives full access to the books, records and other materials of such Companies and their Subsidiaries. If Seller Parent has accepted such Cost Savings Determination in writing or has not given written notice to Buyer setting forth any objection of Seller Parent to such Cost Savings Determination (a “Statement of Objections”) prior to the expiration of the Review Period, then such Cost Savings Determination shall be final and binding upon the Parties. In the event Seller Parent delivers a Statement of Objections during the Review Period, Buyer and Seller Parent shall seek in good faith to agree on the amount of the applicable Cost Savings within ten (10) days following the receipt by Buyer of the Statement of Objections. If Buyer and Seller Parent are unable to reach an agreement as to such amounts and adjustments within such ten (10) day period, then the matter shall be submitted as promptly as practicable to a nationally recognized independent accounting or independent expert firm agreed to by Buyer and Seller Parent (the “Independent Expert”), who shall resolve the matters still in dispute and adjust the Cost Savings Determination and the Cost Savings reflected therein to reflect such resolution; provided, however, that the Independent Expert may not determine an amount of Cost Savings in excess of that claimed by Seller Parent or less than that claimed by Buyer. If, for any reason Buyer and Seller Parent cannot otherwise mutually agree on an Independent Expert, then either party may petition a court of competent jurisdiction to appoint the Independent Expert. The Parties shall cause the Independent Expert to make such determination as soon as reasonably practicable (and in any event within thirty (30) days) following the submission of the matter to the Independent Expert for resolution, and such determination shall be final and binding upon Buyer and Seller Parent and may be entered and enforced in any court having jurisdiction. Each of Buyer and Seller Parent agrees that it shall not have any right to, and shall not, institute any Action of any kind challenging such determination or with respect to the matters that are the subject of this Section 6.18, except that the foregoing shall not preclude an Action to enforce such determination. For the avoidance of doubt, the Independent Expert shall act as an expert, not an arbitrator, and neither this Section 6.18(c) nor the determination of the Independent Expert shall be subject to any relevant state or federal arbitration law.

(j) In the event any dispute is submitted to the Independent Expert for resolution as provided in Section 6.18(i), the fees, charges and expenses of the Independent Expert shall be paid one-half by Buyer and one-half by Seller Parent.

(k) Within five (5) Business Days of each final determination of the Cost Savings pursuant to Section 6.18(f) with respect to a Cost Savings Project that is greater than the Cost Savings set forth in the Cost Savings Determination, Section 6.18 (other than Sections 6.18(h), (i) and (j)) will apply to such excess mutatis mutandis.

6.19 Compliance with Separateness Provisions. Such Company and its Subsidiaries shall at all times comply in all material respects with the Separateness Provisions.

Prior to the conveyance of the Projects owned by the Four Brothers/Three Cedars Seller, such Seller, Seller Parent and Buyers shall use good faith efforts to obtain the consent of the Guarantee Beneficiaries to replace such guarantees (excluding any Excluded Guarantees) at the appropriate Closing with guarantees provided by one or more Buyers or a Buyer Affiliate. If any Guarantee Beneficiary fails to grant such consent, Seller Parent shall use good faith efforts to get approval from lenders to Seller Parent under existing corporate credit facilities, and shall keep Buyers informed regarding such discussions, allowing Seller Parent to keep such guarantees in place following the conveyance of relevant Projects to Buyers, subject to the provision of back-to-back guarantees in form and substance reasonably satisfactory to Seller Parent (the “Back-to-Back Guarantees”) from one or more Buyers or a Buyer Affiliate with creditworthiness that is reasonably acceptable to the Seller Parent. If, by August 15, 2016, each Guarantee Beneficiary has not granted its consent to the replacement of guarantees posted by Seller Parent, and (i) the lenders to Seller Parent have not allowed such guarantees to remain outstanding following such Closing or (ii) any Back-to-Back Guarantee and/or the creditworthiness of any Buyer or Buyer Affiliate providing such Back-to-Back Guarantee is not reasonably satisfactory to Seller Parent, then, the Agreement shall be terminated with respect to Four Brothers Company and Three Cedars Group and, notwithstanding Section 10.03(a), the Note Prepayment Amount for such Company Groups shall be due and payable on the earlier of (x) the sale, transfer (whether through a sale of equity or assets, or merger or similar corporate transaction), assignment, joint venture, or issuance, directly or indirectly of equity in of the Projects held by the Four Brothers Company and Three Cedars Group or any other type of monetization and (y) September 30, 2016.

(as applicable) posted by one or more Buyers (or an Affiliate of Buyers, including any applicable Company Group Entity) no later than June 30, 2016. In connection with the replacement of such letters of credit or bond posted by Seller Parent, the Parties may agree that amounts paid or payable to any of the Buyers under this Agreement (or paid or payable to Buyers pursuant to the Ancillary Agreements) can be used at the applicable Buyer’s discretion to replace Seller Parent letters of credit or bonds (either by cash collateralizing replacement letters of credit or bonds or by cash collateralizing the underlying obligations).

(i) If one or more letters of credit or bonds posted by Seller Parent in connection with obligations of the Four Brothers Company, the Three Cedars Group, the Mount Signal Group, or the Hawaii Group remain outstanding following the Closing of the sale of such Company Group to Buyers:

(1) Buyers shall, upon demand by Seller Parent, pay Seller Parent amounts equal to 8% letter of credit fees and similar fees paid by Seller Parent or its Affiliates in connection with such letters of credit or bonds from such Closing for so long as such letter of credit or bond remains outstanding,

(2) Seller Parent will (i) fund reimbursement obligations arising as a result of a draw on such Seller Parent letters of credit or bond and (ii) cash collateralize such letters of credit or bond if required pursuant to the terms of the Seller Parent’s corporate credit facilities, provided that:

(A) Buyers shall, upon demand by Seller Parent, pay Seller Parent interest on drawn amount or cash collateral at higher of interest charged under Seller Parent’s corporate credit facilities and 10% ;

(B) Seller Parent can offset drawn amounts or cash collateral against (i) the then outstanding principal amount of Exchangeable Notes, (ii) amounts payable to Buyers under this Agreement, (iii) amounts payable to Buyers under Ancillary Agreements or (iv) amounts payable to any Buyers under the 2014 PSA (and if such offset is not effected immediately upon Seller Parent’s reimbursement or cash collateralization, then drawn amounts and cash collateral shall accrue interest at twelve percent (12%) until equivalent obligations are set off); and

(C) In any event, Buyers shall be obligated to repay amounts drawn on a letter of credit or bond and cash collateral posted in respect of a letter of credit or bond no later than the date on which such letter of credit or bond is required to be replaced

(3) No Seller, Seller Parent or any of their Affiliates will, in any event, be obligated to amend, renew or extend the expiration of a letter of credit or bond posted in connection with the obligations of a Company or any of its Subsidiaries which remains outstanding following the Closing with respect to such Company Group.

(vi) (A) by Sellers, solely with respect to the Hawaii Oahu Group, if Buyers do not obtain debt and/or tax equity financing with respect to the Projects of such Company Group as contemplated by Section 6.16(a) and Buyers do not exercise their right to terminate this Agreement with respect to the Hawaii Oahu Group pursuant to paragraph (v) above within the time period set forth therein and (B) by Sellers, solely with respect to the Hawaii Kawailoa Group, if Buyers do not obtain debt and/or tax

(vii) by either party if any court of competent jurisdiction in the United States or other Governmental Authority shall have issued a final Order or taken any other final action restraining, enjoining or otherwise prohibiting the consummation of the transactions with respect to the such Company Group contemplated by this Agreement and such Order or other action is or shall have become final and nonappealable.

(a) If this Agreement is validly terminated pursuant to Section 10.01(a), this Agreement will forthwith become null and void, and there will be no Liability on the part of any Party (or any of their respective Representatives or Affiliates) in respect of this Agreement, except that (a) the provisions with respect to indemnification in Article XI, expenses in Section 12.02 and confidentiality in Section 12.03, and this Section 10.02 and Sections 10.03, 12.12, 12.14, 12.15, 12.16, 6.09, 6.14(b), 6.14(c), 6,16(a), 6.16(b) and 6.16(f) will continue to apply following any termination, and (b) nothing in this Section 10.02 shall release any Party from Liability for any (i) willful failure of such Party to fulfill a condition to the performance of the material obligations of another Party, (ii) failure to perform a material covenant of this Agreement or (iii) breach by such Party of any material representation or warranty or agreement contained herein.

(b) If the provisions of this Agreement with respect to any Company Group are validly terminated pursuant to Section 10.01(b), such provisions will forthwith become null and void with respect to such Company Group, and there will be no Liability on the part of any Party (or any of their respective Representatives or Affiliates) in respect of such provisions in relation to such Company Group, except that (a) the provisions with respect to indemnification in Article XI, expenses in Section 12.02 and confidentiality in Section 12.03, and this Section 10.02 and Sections 10.03, 12.12, 12.14, 12.15, 12.16, 6.09, 6.14(b), 6.14(c), 6,16(a), 6.16(b) and 6.16(f) will continue to apply following any termination, and (b) nothing in this Section 10.02 shall release any Party from Liability for any willful (i) failure of such Party to fulfill a condition to the performance of the material obligations of another Party, (ii) failure to perform a material covenant of this Agreement or (iii) breach by such Party of any material representation or warranty or agreement contained herein.

(a) Except as otherwise provided in this Agreement, in the event of a termination of this Agreement by any Buyer pursuant to Section 10.01(b)(iii) or by any Seller pursuant to Section 10.01(b)(iv) or (v), then, within twenty (20) days of such termination, Seller Parent or Note Issuer shall purchase, and each Buyer shall sell, an aggregate principal amount of Exchangeable Notes equal to its pro rata share of the Note Prepayment Amount for the Company Group (as set forth on Schedule A) with respect to which such termination has occurred, in accordance with the Exchangeable Notes Indenture. The Parties agree that, upon payment in full in cash of any Buyer’s pro rata share of the Note Prepayment Amount together with all accrued and unpaid interest on the Exchangeable Note held by such Buyer, such Buyer shall cause all of the Exchangeable Notes held by it to be delivered to the Note Trustee on behalf of Note Issuer, through the facilities of the Depositary, for cancellation in accordance with Section 2.12 of the Exchangeable Note Indenture.

(b) Each of Seller Parent and Note Issuer acknowledges that it shall have no right under this Agreement to offset any amount owed (or to become due and owing) to it, whether under this Agreement or otherwise, against its obligations to make payment required to be made under this Agreement.

(c) The Parties acknowledge that the agreements contained in this Section 10.03 are an integral part of the transactions contemplated by this Agreement and that, without these agreements, the Parties would not enter into this Agreement.

(d) Notwithstanding anything to the contrary in this Agreement, if this Agreement is terminated as described in Section 10.03(a) and Seller Parent and Sellers were not otherwise obligated to close the transactions contemplated by this Agreement pursuant to Section 2.02 at the time of such termination, any Buyer’s right to cause payment of the Note Prepayment Amount by Seller Parent pursuant to Section 10.03(a) shall be the sole and exclusive remedy of Buyers and any Person claiming by, through or for the benefit of Buyers against (i) Seller Parent or Sellers, (ii) the former, current and future holders of any equity, partnership or limited liability company interest, controlling persons, directors, officers, employees, agents, attorneys, Affiliates, members, managers, general or limited partners, stockholders or assignees of any Person named in clause (i), and (iii) any future holders of any equity, partnership or limited liability company interest, controlling persons, management companies, directors, officers, employees, agents, attorneys, representatives, Affiliates, members, managers, general or limited partners, or shareholders of any of the foregoing for any losses (whether in law or equity and whether based on contract, tort or otherwise) suffered as a result of any breach of any representation, warranty, covenant or agreement, the failure of the transactions contemplated by this Agreement to be consummated, based upon, arising out of or relating to this Agreement (including any breach or alleged breach hereof or thereof), the negotiation, execution or performance hereof or the transactions contemplated hereby or in respect of any oral or written representations made or alleged to be made in connection herewith, whether at law or equity, in contract, in tort or otherwise. Notwithstanding the foregoing, the foregoing limitations shall not apply to claims arising out of Company Groups with respect to which a Closing has occurred prior to termination of this Agreement.

(a) The representations and warranties contained in Sections 4.03, 4.07, 4.08, 4.09, 4.10, 4.11, 4.13, 4.14, 4.16 and 4.19 of this Agreement or in any certificate with respect thereto delivered pursuant to this Agreement, in each case, as they relate to matters related to a Company Group, Equity Interest with respect to such Company Group, or Sellers with respect to such Company Group and the representations and warranties of Buyers contained in Sections 5.03, 5.04 and 5.05 as they relate to matters related a Company Group, Equity Interest with respect to such Company Group, or Sellers with respect to such Company Group shall survive the Closing with respect to such Company Group for fifteen (15) months following such Closing. Each of the other representations and warranties contained in this Agreement (such other representations that are set forth in Article IV or Article V, the “Fundamental Representations”) shall survive until ninety (90) days after the expiration of the applicable statute of limitations (including any extensions thereto to the extent that such statute of limitations may be tolled).

(b) If a Party delivers an indemnification notice to the other Party before the expiration of a representation or warranty, then the right to assert a claim for indemnification with respect to the applicable representation or warranty shall survive until the resolution of the matter covered by such notice. No claim for indemnification may be made after the expiration of the applicable survival period.

(a) Subject to the limitations set forth in this Article XI, subsequent to the Closing Date, (i) Seller Parent shall, jointly and severally with each other Seller, and Sellers shall, severally and not jointly, indemnify, hold harmless and defend Buyers and their Affiliates against any liability, loss, cost, expense or reasonable attorneys’ fees or Action (collectively, “Losses” and individually, a “Loss”) that any of the foregoing suffers as a result of any breach or inaccuracy of the representations and warranties (each such breach a “Warranty Breach”) of any Seller set forth in Article IV.

(b) Subject to the limitations set forth in this Article XI, subsequent to the Closing Date with respect to a Company Group, each Buyer shall severally, but not jointly, indemnify, hold harmless and defend the Sellers and their Affiliates against any Loss that any of the foregoing suffers as a result of any breach or inaccuracy of the representations and warranties by such Buyer set forth in Article V relative to matters related to the Company Group with respect to which such Closing Date has occurred

11.03 Third Party Claims. The obligations and liabilities of an Indemnifying Party with respect to Losses resulting from the assertion of liability by third parties (each, a “Third Party Claim”) shall be subject to the following terms and conditions:

(a) The Indemnified Party shall promptly give written notice to the Indemnifying Party of any Third Party Claim that might give rise to any Loss by the Indemnified Party, stating the nature and basis of such Third Party Claim, and the amount thereof to the extent known; provided, however, that no delay on the part of the Indemnified Party in so notifying the Indemnifying Party shall relieve the Indemnifying Party from any obligation hereunder except to the extent the Indemnifying Party is materially prejudiced thereby. Such notice shall be accompanied by copies of all relevant documentation with respect to such Third Party Claim, including any summons, complaint or other pleading that may have been served, any written demand or any other document or instrument.

(b) From and after receipt of notice of a Third Party Claim pursuant to Section 11.03(a), the Indemnifying Party shall have the right to assume and conduct, at its own expense, the defense against the Third Party Claim in its own name or in the name of the Indemnified Party with counsel reasonably acceptable to the Indemnified Party if the Indemnifying Party has, based on the facts and circumstances available at the time, unconditionally acknowledged in writing its obligation to indemnify the Indemnified Party in respect of such Third Party Claim in accordance with and subject to the terms of this Agreement and without prejudice to the amount of any Loss. Any Indemnified Party shall have the right to employ separate counsel in any such Third Party Claim and/or to participate in the defense thereof, but the fees and expenses of such counsel shall not be included as part of any Loss incurred by the Indemnified Party and shall not be payable by the Indemnifying Party; provided, however, that if the representation of any such Indemnified Party by the same counsel as the Indemnifying Party would be inappropriate under applicable standards of professional conduct, the Indemnified Party shall be entitled to appoint one separate counsel for such claims and defenses, at the reasonable cost and expense of the Indemnifying Party. The party or parties conducting the defense of any Third Party Claim shall keep the other parties apprised of all significant developments with respect thereto and shall not enter into any settlement, compromise or consent to judgment with respect to such Third Party Claim without the prior consent of the other parties thereto, such consent not to be unreasonably withheld; provided, however, that the Indemnifying Party shall be entitled to settle, compromise or consent to a judgment without the consent of the Indemnified Party with respect to a Third Party Claim that only imposes monetary obligations that are paid by the Indemnifying Party and contains a release of the Indemnified Party from all liability thereunder. The Indemnified Party shall make available all information and assistance for the defense of the Third Party Claim as the Indemnifying Party may reasonably request and shall cooperate with the Indemnifying Party in such defense.

(c) Notwithstanding the foregoing, if a Buyer determines in good faith that an adverse determination with respect to a Third Party Claim would reasonably be expected to be materially detrimental to the future business prospects or operations of the Companies, taken as a whole, such Buyer may, by notice to the Indemnifying Party, assume the exclusive right to defend, compromise or settle such Third Party Claim; provided that the Indemnifying Party will not be bound by any compromise or settlement effected without its consent.

(a) As to any claim for Warranty Breach (other than with respect to a claim for a breach or inaccuracy of a Fundamental Representation) with respect to any Company

Group, the Indemnified Party shall not be entitled to indemnification (i) with respect to any Loss or a series of related Losses for less than $100,000, (ii) until all Losses (including any de minimis Loss excluded pursuant to the foregoing clause (i)) to such Indemnified Party exceed, in the aggregate, an amount equal to the Applicable Deductible and then only to the extent of such excess, and (iii) in no event shall the Indemnifying Party be responsible for Losses in excess of the Applicable Cap in the aggregate. “Applicable Cap” means, with respect to a Company Group, fifteen (15)% of the applicable Company Group Amount for such Company Group. “Applicable Deductible” means, with respect to a Company Group, 1% of the applicable Company Group Amount for such Company Group.

(b) In no event shall any Buyer be liable for any Losses as to any claim for indemnification based on an inaccuracy or breach of any representation and warranty with respect to any Company Group in excess of such Buyer’s pro rata share of the Applicable Cap with respect to such Company Group.

(c) Solely for the purposes of this Article XI, from and after Closing any reference to “material”, “materially” or “Material Adverse Effect” in any representation or warranty (other than those representations and warranties in Sections 4.01(b), 4.09, 4.11, 4.13 and 4.14) shall be disregarded solely for purposes of determining the amount of Losses attributable to any Warranty Breach, and for purposes of determining whether there has actually been a Warranty Breach.

(d) Buyers and the Sellers and Seller Parent on behalf of each of their respective Indemnified Parties waives any right to recover, indirect, special, exemplary or punitive damages, unless such indirect, special, exemplary, punitive or other kind of special damages are awarded to a Person in an indemnifiable Third Party Claim.

(e) Each Person entitled to indemnification hereunder shall use commercially reasonable efforts to mitigate all Losses upon becoming aware of any event or circumstance that could reasonably be expected to give rise to any Losses that are indemnifiable under this Article XI. If such Indemnified Party mitigates its Losses after the Indemnifying Party has paid the Indemnified Party under any indemnification provision of this Agreement in respect of that loss, the Indemnified Party must notify the Indemnifying Party and pay to the Indemnifying Party the extent of the value of the benefit to the Indemnified Party of that mitigation (less the Indemnified Party’s reasonable costs of mitigation) within two Business Days after the benefit is received, but such payment shall not exceed the indemnity payment paid by the Indemnifying Party.

(f) Any indemnifiable claim with respect to any breach by a Party of a representation and warranty shall be net of any insurance proceeds received by the Indemnified Party or amounts actually recovered from any other Person alleged to be responsible therefor (net of any costs of collection, increased premium or other out-of-pocket costs related to the insurance claim or third party recovery in respect of Losses). If the Indemnified Party receives any amounts under applicable insurance policies, or from any other Person alleged to be responsible for any Losses, subsequent to an indemnification payment by the Indemnifying Party, then such Indemnified Party shall promptly reimburse the Indemnifying Party for any payment made or expense incurred by such Indemnifying Party in connection with providing such indemnification payment up to the amount received by the Indemnified Party (net of any costs of collection, increased premium or other out-of-pocket costs related to the insurance claim or third party recovery in respect of Losses).

(g) Any Losses as to an indemnifiable claim with respect to any breach or nonperformance by a Party of a representation, warranty, covenant or agreement shall be calculated without reduction for any Tax Benefit available to the Indemnified Party. However, to the extent that the Indemnified Party actually realizes a Tax Benefit as a result of any Loss in any taxable year in which or prior to which such Loss was incurred, the Indemnified Party shall pay the amount of such Tax Benefit (but not in excess of the indemnification payment or payments actually received from the Indemnifying Party with respect to such Loss) to the Indemnifying Party as such Tax Benefit is actually realized by the Indemnified Party. For this purpose, the Indemnified Party shall be deemed to realize a tax benefit (“Tax Benefit”) with respect to a taxable year if, and to the extent that, the Indemnified Party’s cumulative liability for Taxes through the end of such taxable year, calculated by excluding any Tax items attributable to the Loss from all taxable years, exceeds the Indemnified Party’s actual cumulative liability for Taxes through the end of such taxable year, calculated by taking into account any Tax items attributable to the Loss for all taxable years (to the extent permitted by relevant Tax law and treating such Tax items as the last items claimed for any taxable year).

11.05 Remedies Exclusive. The indemnification rights of the Parties under this Article XI are the exclusive remedies after the applicable Closing available to the Parties and any Indemnified Party with respect to any claims or disputes arising with respect to breaches of representations set forth in Article IV and Article V other than claims involving fraud, with respect to which the Parties’ rights and remedies shall not be affected or diminished hereby.

12.01 Entire Agreement. This Agreement and the Ancillary Agreements supersede all prior discussions and agreements among the Parties with respect to the subject matter hereof and thereof, and contain the sole and entire agreement among the Parties with respect to the subject matter hereof and thereof.

12.02 Expenses. Buyers shall deliver to Seller Parent (a) no later than five (5) Business Days after the date hereof, a statement of their reasonable and documented fees and expenses incurred prior to the date hereof in connection with the negotiation, execution and consummation of the transactions contemplated by this Agreement (including the transactions to be consummated on each Closing), the 2014 PSA and the Exchangeable Note Indenture and the exercise of any of their rights and remedies in connection therewith (which fees and expenses shall be due and payable solely for purposes of the definition of “Net Note Principal Amount” as of the date hereof), and (b) no later than five (5) Business Days after each Closing Date, a statement of their reasonable and documented fees and expenses incurred or estimated to be incurred prior to such Closing Date in connection with the negotiation, execution and consummation of the transactions contemplated by this Agreement (including the transactions to be consummated on such Closing and any amendment or waiver of this Agreement) (which fees and expenses shall be due and payable solely for purposes of the definition of “Net Note

Principal Amount” as of such Closing Date) (collectively, with the fees and expenses referred to in clause (a), the “Transaction Expenses”). Seller Parent shall reimburse Buyers for (1) all of the Transaction Expenses subject to the terms of this Agreement and (2) their reasonable fees and expenses incurred after the date hereof in connection with the exercise of their rights and remedies in connection with the 2014 PSA (as amended on the date hereof), the Exchangeable Note Indenture or this Agreement upon submission of invoices therefor.

12.03 Confidentiality. From and after the applicable Closing, Sellers will hold, and will use their reasonable best efforts to cause their Affiliates and Representatives to hold, in strict confidence from any other Person all information and documents relating to the Companies, provided that nothing in this sentence shall limit the disclosure by any Party of any information (a) to the extent required by Applicable Law or judicial process (provided that if permitted by Applicable Law, Sellers agree to give Buyers prior notice of such disclosure), (b) in connection with any litigation among the Parties or their Affiliates, (c) in an Action brought by a Party in pursuit of its rights or in the exercise of its remedies under this Agreement, (d) to the extent that such documents or information can be shown to have come within the public domain through no action or omission of the disclosing Party or its Affiliates in violation hereof, (e) to its Affiliates (but the Party shall be liable for any breach by its Affiliates), (f) to its actual or prospective investors, advisors, lenders, underwriters, legal representatives or other third parties who have a reason to know and (g) to investors, purchasers or other assignees of any Company or any Company Subsidiary.

12.04 Announcements. No Party shall, directly or indirectly, issue any press release or other public statement relating to the terms of this Agreement or the transactions contemplated hereby or use the other’s name or refer to the other directly or indirectly in connection with its relationship with the other in any media interview, advertisement, news release, press release or professional or trade publication, or in any print media, whether or not in response to an inquiry, without the prior written approval of the other Parties, unless required by Applicable Law or the applicable requirements of a regulated securities exchange, provided that each Party will be given a reasonable opportunity to review and comment on any proposed press release or other public statement by any other Party required by Applicable Law or such requirements prior to its issuance.

12.05 No Waiver. No failure on the part of any Party to exercise and no delay in exercising, and no course of dealing with respect to, any right, remedy, power or privilege under this Agreement shall operate as a waiver of such right, remedy, power or privilege, nor shall any single or partial exercise of any right, remedy, power or privilege under this Agreement preclude any other or further exercise of any such right, remedy, power or privilege or the exercise of any other right, remedy, power or privilege. The rights, remedies, powers and privileges provided in this Agreement are cumulative and not exclusive of any rights, remedies, powers and privileges provided by Applicable Law.

12.06 Amendments. Any provision of this Agreement may be amended, modified, supplemented or waived only by an instrument in writing duly executed by Seller Parent, MDCP and DESCH. Any such amendment, modification, supplement or waiver shall be for such period and subject to such conditions as shall be specified in the instrument effecting the same and shall be binding upon the Parties, and any such waiver shall be effective only in the specific instance and for the purposes for which given.

12.07 Notices. All notices and other communications given or made pursuant hereto shall be in writing and shall be deemed to have been duly given or made as of the date delivered or sent if delivered personally or sent by facsimile or electronic transmission in PDF format, on the next Business Day if sent by prepaid overnight carrier (providing proof of delivery) or on the fifth (5th) Business Day following the date of mailing if delivered by registered or certified mail (postage prepaid, return receipt requested) to the Parties at the following addresses, facsimile numbers or email addresses (or at such other addresses, facsimile numbers or email addresses as shall be specified by the Parties by like notice):

12.08 Captions. The captions and section headings appearing in this Agreement are included solely for convenience of reference and are not intended to affect the interpretation of any provision of this Agreement.

12.09 Severability. Any provision of this Agreement that is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions of this Agreement, and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction and, in lieu of such prohibited 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 prohibited or unenforceable provision as may be possible.

(a) Subject to Section 12.10(b), the rights and obligations of the Parties under this Agreement are not assignable without the prior written consent of the other Parties, which such Parties may withhold in their discretion.

(b) Any Buyer may assign this Agreement to one or more of (i) such Buyer’s Affiliates, (ii) another Buyer or any of its Affiliates or (iii) any Person in which one or more Buyers or their respective Affiliates are members. Any Buyer may assign this Agreement or any of its rights hereunder to one or more third parties who acquire interests in any Company; provided that such assignment shall not relieve such Buyer of any of its obligations hereunder or enlarge, alter or change any obligation of another Party, and may assign rights and obligations hereunder in connection with the sale, assignment, financing or other transfer of any Company and/or its Subsidiaries.

12.11 Counterparts; Third Party Beneficiaries. This Agreement may be executed in any number of counterparts, all of which taken together shall constitute one and the same instrument and any of the Parties may execute this Agreement by signing any such counterpart. No provision of this Agreement is intended to confer any rights, benefits, remedies, obligations, or liabilities hereunder upon any Person other than the Parties and their respective successors and assigns; provided that Section 6.11 and this Section 12.11 are intended to be for the benefit of, and enforceable by, the Persons named therein.

12.12 Disclosure. Sellers have set forth information on the Disclosure Schedule in a section thereof with respect to a Company Group that corresponds to the section of this Agreement and Company Group to which it relates. Information disclosed in any Disclosure

Schedule shall constitute a disclosure for purposes of all other Disclosure Schedules notwithstanding the lack of specific cross-reference thereto, but only to the extent the applicability of such disclosure to such other Disclosure Schedule is reasonably apparent on its face. The Parties acknowledge and agree that (a) the Disclosure Schedule may include certain items and information solely for informational purposes for the convenience of Buyers and (b) the disclosure by Sellers of any matter in the Disclosure Schedule shall not be deemed to constitute an acknowledgment by Sellers that the matter is required to be disclosed by the terms of this Agreement or that the matter is material.

12.13 Specific Performance. The Parties agree that if any of the provisions of this Agreement were not performed in accordance with their specific terms or were otherwise breached, irreparable damage would occur, money damages would not be a sufficient remedy and that the Parties shall be entitled to specific performance of the terms of this Agreement and immediate injunctive relief, without the necessity of proving the inadequacy of money damages as a remedy, in addition to any other remedy at law or in equity. For clarity, no Buyer is obligated to close with respect to any applicable Closing if the conditions to such Closing have not been satisfied.

12.14 Governing Applicable Law. THIS AGREEMENT SHALL BE GOVERNED BY, AND CONSTRUED IN ACCORDANCE WITH, THE LAWS OF THE STATE OF NEW YORK APPLICABLE TO CONTRACTS MADE AND TO BE PERFORMED IN THAT STATE.

(a) For all purposes of this Agreement, and for all purposes of any Action arising out of or relating to the transactions contemplated hereby or for recognition or enforcement of any judgment, each Party submits to the personal jurisdiction of the courts of the State of New York and the federal courts of the United States sitting in New York County, and hereby irrevocably and unconditionally agrees that any such Action shall be heard and determined in such New York court or, to the extent permitted by Applicable Law, in such federal court. Each Party agrees that a final judgment in any such Action may be enforced in any other jurisdiction by suit on the judgment or in any other manner provided by Applicable Law.

(b) Each Party irrevocably and unconditionally waives, to the fullest extent it may legally and effectively do so:

(i) any objection which it may now or hereafter have to the laying of venue of any Action arising out of or relating to this Agreement or any related matter in any New York state or federal court located in New York County; and

(ii) the defense of an inconvenient forum to the maintenance of such Action in any such court.

(c) Each Party irrevocably consents to service of process by registered mail, return receipt requested, as provided in Section 12.07. Nothing in this Agreement will affect the right of any Party to serve process in any other manner permitted by Applicable Law.

12.16 Waiver of Jury Trial. TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, EACH PARTY HEREBY WAIVES ALL RIGHTS TO A TRIAL BY JURY IN ANY LEGAL ACTION TO ENFORCE OR INTERPRET THE PROVISIONS OF THIS AGREEMENT OR THAT OTHERWISE RELATES TO THIS AGREEMENT.

IN WITNESS WHEREOF, this Agreement has been duly executed and delivered by the duly authorized officer of each Party as of the date first above written.
