Except as set forth in this Section 2.03(e), nothing herein is intended, nor shall it be deemed to, amend any Benefit Plan. Section 2.04 Closing Purchase Price Adjustment. (a) For purposes of this Agreement, the following terms shall have the respective meanings assigned to such terms below: (i) “Accounts Receivable” means the accounts receivable of the Companies, without duplication, as of the Effective Time, in each case, (A) calculated in accordance with GAAP and in a manner consistent with those methodologies, policies, procedures, practices, estimation techniques, assumptions and principles set forth on Schedule II and (B) excluding any Closing Cash. (ii) “Accounts Payable” means the accounts payable, accrued expenses, and other current liabilities of the Companies (including refunds and credits owed to customers and vendors, Taxes and employees’ accrued but unpaid salary, wages, vacation and paid time off), without duplication, as of the Effective Time, in each case, (A) calculated in accordance with GAAP and in a manner consistent with those methodologies, policies, procedures, practices, estimation techniques, assumptions and principles set forth on Schedule II and (B) excluding any amounts included in Closing Indebtedness or Transaction Expenses. (iii) “Net Trade Working Capital” means an amount equal to the sum of: (A) Accounts Receivable minus (B) Accounts Payable. (iv) “Target Net Trade Working Capital” means $1,000,000.00. (b) Estimate by Sellers. At least three (3) Business Days, but not more than five (5) Business Days, prior to the anticipated Closing Date, Sellers shall deliver to Buyer a written notice setting forth the Sellers’ good faith estimate, as of the anticipated Closing Date, of each of (i) the Closing Indebtedness (the “Estimated Closing Indebtedness”) and (ii) the Transaction Expenses (the “Estimated Transaction Expenses”). (c) Closing Statement. As promptly as practicable, but no later than one hundred twenty (120) days after the Closing Date, Buyer shall prepare and deliver, or cause to be prepared and delivered, to Sellers (i) a written statement of Buyer’s calculation of each of the Trade Working Capital, Closing Cash, Closing Indebtedness and Transaction Expenses (the “Closing Statement”) and (ii) statements supporting the calculations thereof, including supporting documentation and work papers with respect thereto. 6 302010047 v18

(d) Examination and Review. The Closing Statement delivered by Buyer to Sellers shall be final, conclusive and binding upon the parties unless Sellers, within forty-five (45) days after delivery to Sellers of the Closing Statement, notifies Buyer in writing that Sellers dispute any of the amounts set forth therein (a “Dispute Notice”). To be valid and effective, the Dispute Notice shall contain a specific list of the disputed line items and, for each individual disputed line item, reasonable detail regarding the nature and the basis for such disputed line item and Sellers’ proposed calculation thereof (each such item, a “Disputed Item”). Prior to the final resolution of the Closing Statement, Buyer may supplement or revise its position with respect to any item or amount contained in the Closing Statement. Any supplement delivered by Buyer shall be deemed an amendment to the Closing Statement and shall entitle Sellers to amend its Dispute Notice (and the Disputed Items) in its entirety by delivery of an amended Dispute Notice within thirty (30) days after delivery to Sellers of such supplemental or revised items. If a timely Dispute Notice is delivered by Sellers, then the Closing Statement shall become final, conclusive and binding on the parties on the earlier of (i) the date Buyer and Sellers resolve in writing any differences they have with respect to all Disputed Items and (ii) the date all Disputed Items are finally resolved in writing by the Independent Accountant. (e) Resolution of Disputes. Buyer and Sellers shall in good faith attempt to resolve all Disputed Items and, if Buyer and Sellers so resolve all such Disputed Items, the Closing Statement, as amended to the extent necessary to reflect the agreed resolution of the Disputed Items, shall be final, conclusive and binding on the parties, absent manifest error. Notwithstanding their good faith efforts, if Buyer and Sellers do not reach agreement resolving the Disputed Items within thirty (30) days after such Dispute Notice (or amended Dispute Notice if Buyer supplements its position pursuant to Section 2.04(d) and such amended Dispute Notice is timely and properly delivered to Buyer), either Buyer or Sellers may submit the dispute to PricewaterhouseCoopers or, if PricewaterhouseCoopers is unwilling or unable to serve, an independent accounting firm of national reputation mutually agreeable to Buyer and Sellers (PricewaterhouseCoopers or such other mutually agreeable independent accounting firm, the “Independent Accountant”). If either Buyer or Sellers submit the dispute to the Independent Accountant then each party shall take all actions reasonably requested by the Independent Accountant in connection with resolving such dispute, including submitting written claims to the Independent Accountant, if so requested, and each party shall request that the Independent Accountant deliver to Buyer and Sellers its resolution in writing not more than thirty (30) days after its engagement. All determinations made by the Independent Accountant shall be in writing and shall be final, conclusive and binding on the parties absent fraud or manifest error. In resolving any Disputed Item, the Independent Accountant (i) shall be bound by the provisions of this Section 2.04, including the matters set forth on Schedule II and (ii) may not assign a value to any individual Disputed Item greater than the greatest value for such Disputed Item claimed by Buyer or Sellers or less than the smallest value for such Disputed Item claimed by Buyer or Sellers. None of Sellers, Buyer and the Companies (and none of their respective Representatives) shall have any ex parte conversations or meetings with the Independent Accountant without the prior consent (not to be withheld, conditioned or delayed unreasonably) of (i) with respect to Sellers, Buyer, and (ii) with respect to Buyer and the Companies, Sellers. The fees, costs and expenses of the Independent Accountant shall be allocated to and borne by Buyer, on the one hand, and Sellers, on the other, based on the inverse of the percentage that the Independent Accountant’s determination (before such allocation) bears to the total amount of the Disputed Items as originally submitted to the Independent Accountant. For example, if Sellers claim that the Net Trade Working Capital is $1,000 greater than the amount claimed by Buyer, if Buyer contests only $500 of such amount claimed by Sellers and if the Independent Accountant ultimately resolves the dispute by awarding Sellers $300 of the $500 so contested, then the fees, costs and expenses of the Independent Accountant will be allocated sixty percent (60%) (i.e., 300 ÷ 500) to Buyer and forty percent (40%) (i.e., 200 ÷ 500) to Sellers. Any fees, costs and expenses allocated to and to be borne by a party pursuant to the foregoing sentence shall be paid by such party, or its designee, within five (5) Business Days of receipt of any invoice or xxxx for such fees, costs and expenses. “Final Closing Statement” means (i) Buyer’s Closing Statement delivered pursuant to Section 2.04(c) if no Dispute Notice is timely delivered by Sellers pursuant to 7 302010047 v18

Section 2.04(d); or (ii) if a Dispute Notice is timely delivered, (A) as agreed by Buyer and Sellers pursuant to Section 2.04(e) or (B) in the absence of such agreement, as shown in the Independent Accountant’s calculation delivered pursuant to Section 2.04(e). (f) Cooperation.

ARTICLE VI COVENANTS Section 6.01 Confidentiality. The Confidentiality Agreement and the obligations of the parties thereunder shall terminate on the Closing. For the avoidance of doubt, the fact that this Agreement has been entered into between the parties, and the terms and conditions hereof, (a) shall be subject to the terms of the Confidentiality Agreement, and (b) Sellers shall, and shall cause each of their Affiliates (including, prior to the Closing, the Companies) to, hold, and shall use their reasonable best efforts to cause their Representatives to hold, in confidence and not disclose, directly or indirectly, such matters, in each case except as disclosure hereof and thereof is expressly contemplated and permitted pursuant to the terms and conditions of this Agreement. From and after the Closing, Sellers shall, and shall cause each of their Affiliates to, hold, and shall use their reasonable best efforts to cause their Representatives to hold, in confidence and not disclose, directly or indirectly, any and all information, whether written or oral, concerning the Companies, including any and all Trade Secrets, proprietary information, and confidential information of the Companies, except to the extent that Sellers can show that such information is or becomes publicly available through no fault of Sellers or any of their respective Affiliates or Representatives, or to the extent necessary in connection with providing continuing services to the Companies, in each case, at and in accordance with the request of the applicable Company. If a Seller or any of his or her Affiliates or Representatives are compelled to disclose any such information by judicial or administrative process or by other requirements of Law, such Seller shall promptly notify Buyer in writing and shall disclose only that portion of such information that such Seller or his or her respective Affiliates or Representatives are advised by their counsel in writing is legally required to be disclosed; provided, however, that such Seller shall use, and cause his or her respective Affiliates and Representatives to use, reasonable best efforts to obtain an appropriate protective order or other reasonable assurance that confidential treatment will be accorded such information, at the cost and expense of Buyer. Section 6.02 Non-competition; Non-solicitation. (a) Each Seller acknowledges the highly competitive nature of the business of the Companies. In connection with the sale of all of its Securities, including the Companies’ goodwill, in exchange for good and valuable consideration offered to such Seller for its Securities, for a period of five (5) years commencing on the Closing Date (the “Restricted Period”), each of the Sellers (collectively, the “Non-Compete Parties”) agrees that he or she shall not, and shall not permit any of his or her Affiliates to, directly or indirectly, whether acting alone or as a partner, shareholder, member joint venture, equity or security holder, officer, director, employee, principal, agent, trustee, consultant, independent contractor or lender (other than in connection with providing services to any Company or other Affiliate of Buyer, including any entity acquired by any Company or Buyer or its Affiliates after Closing, in each case, at and in accordance with the request of such Company), (i) engage in or assist others in engaging in the Restricted Business in the Territory; (ii) have an interest in any Person that engages, directly or indirectly, in the Restricted Business in the Territory in any capacity, including as a partner, shareholder, member, joint venture, equity or security holder, officer, director, employee, principal, agent, trustee, consultant, independent contractor or lender; or (iii) intentionally interfere in any material respect with the business relationships (whether formed prior to or after the date of this Agreement) between any Company and any customers or suppliers of such Company.

(b) During the Restricted Period, the Non-Compete Parties shall not, and shall not permit any of its Affiliates to, directly or indirectly, for themselves or another, solicit for employment any 31 302010047 v18

current or former employee, contractor, or consultant of any Company, encourage any such employee, contractor, or consultant to leave such employment or contract period with Buyer or its Affiliates, or hire, retain, or otherwise utilize the services of (whether as an employee, consultant, volunteer or otherwise) any such employee, contractor, or consultant so solicited or encouraged, except pursuant to a general solicitation that is not directed specifically to any such employees, contractors, or consultants; provided, however, that nothing in this Section 6.02(b) shall prevent the Non-Compete Parties or any of their Affiliates from soliciting (i) after six months any employee whose employment or contract has been terminated by the applicable Company or Buyer, (ii) after six months from the date of termination of employment or contract period, any employee, contractor, or consultant whose employment or contract has been terminated by the employee, contractor, or consultant or (iii) the individual set forth in Section 6.02(b) of the Disclosure Schedules.

(d) The Non-Compete Parties acknowledge and agree (i) that the provisions of, and Sellers’ obligations under, Section 6.01 and Section 6.02 are reasonable in scope and necessary for the protection of Buyer and its legitimate business interests, and constitute a material inducement to Buyer to enter into this Agreement and consummate the transactions contemplated by this Agreement, (ii) that any of the Non-Compete Parties’ breach or threatened breach of any provision or obligation in this Section 6.01 or Section 6.02 would give rise to irreparable harm to Buyer for which monetary damages would not be an adequate remedy, and (iii) that Buyer shall be entitled to seek and obtain, in addition to any and all other rights and remedies that may be available to it in respect of such breach, equitable relief, including a temporary restraining order, an injunction, specific performance and any other relief that may be available from a court of competent jurisdiction, to prevent and/or remedy such a breach or threatened breach (without first having to demonstrate any actual damage, post any bond or furnish any other security interest thereof). In any proceeding for an injunction and upon any motion for a temporary or permanent injunction, Buyer’s right to receive monetary damages shall not be a bar, or be interposed as a defense, to the granting of such relief. Buyer’s right to injunctive relief is in addition to, and not in lieu of, any other rights and remedies available to it or them under law or in equity. Each Non-Compete Party agrees that the provisions of this Section 6.01 and Section 6.02 shall be assignable to and enforceable by any successor to or assignee of Buyer, the Companies or the business of the Companies. (e) In the event that any covenant contained in Section 6.01 or Section 6.02 should ever be adjudicated to exceed the time, geographic, product or service, or other limitations permitted by Law in any jurisdiction, then any court is expressly empowered to reform such covenant, and such covenant shall be deemed reformed, in such jurisdiction to the maximum time, geographic, product or service or other limitations permitted by Law. The covenants contained in Section 6.01 and Section 6.02 and each provision hereof are severable and distinct covenants and provisions. The invalidity or unenforceability of any such covenant or provision as written shall not invalidate or render unenforceable the remaining covenants or provisions hereof, and any such invalidity or unenforceability in any jurisdiction shall not invalidate or render unenforceable such covenant or provision in any other jurisdiction. 32 302010047 v18

(f) If any Non-Compete Party or any Affiliate of any Non-Compete Party violates this Section 6.02, then the period of time during which the provisions thereof are applicable will automatically be extended for a period of time equal to the time that such violation began until such violation permanently ceases as (i) agreed to between any such breaching Non-Compete Party or any Affiliate of any Non- Compete Party and Buyer, or (ii) as finally determined by a court of competent jurisdiction. Section 6.03 Governmental Approvals and Consents. (a) If any consent, approval or authorization necessary to preserve any right or benefit under any Contract to which any Company is a party is not obtained prior to the Closing, Sellers shall, subsequent to the Closing, cooperate with Buyer and the Companies in attempting to obtain such consent, approval or authorization as promptly thereafter as practicable. If such consent, approval or authorization cannot be obtained, Sellers shall use their reasonable best efforts to provide the Companies with the rights and benefits of the affected Contract for the term thereof, and, if Sellers provide such rights and benefits, the applicable Company shall assume all obligations and burdens thereunder. (b) Sellers shall use their commercially reasonable efforts to obtain or provide, at the earliest practicable date as determined by Sellers and Buyer, each consent, waiver, approval, Order, Permit (including any Environmental Permit) or authorization of, or declaration or filing with, or notification to, any Governmental Authority required or necessary pursuant to any Material Contract, Permit, or applicable Law, including any Environmental Law, Environmental Notice, or Environmental Permit (whether with or without notice or lapse of time or both) applicable to any Company, any Real Property, or any assets, business or operations with respect thereto in connection with, as a result of or arising from the consummation of the transactions contemplated by this Agreement or the Transaction Documents (any such consent, waiver, approval, Order, Permit (including any Environmental Permit) or authorization of, or declaration or filing with, or notification to, any Governmental Authority not obtained prior to the Closing, the “Outstanding Consents”); provided, however, that any Losses arising in connection with the failure to obtain or provide an Outstanding Consent shall be and is agreed to constitute an Excluded Item and Loss indemnifiable pursuant to Section 8.02(h); provided further, that for the avoidance of doubt, any approvals or clearances under the HSR Act shall not constitute Outstanding Consents. The parties hereto agree that they will keep the other parties apprised in a timely manner of the status of matters referred to in this Section 6.03 and, to the extent permitted by Law, promptly furnish the others with copies of notices or other communications (or, in the case of material oral communications, advise the other of such communications (orally or otherwise)) between the parties hereto and their representatives, as the case may be, and any Governmental Authority with respect to such transactions.

Section 6.09 Insurance. (a) Buyer and Sellers acknowledge that prior to the Closing, Sellers have deposited $210,000 (the “Insurance Escrow Amount”) with Ruskin Moscou Faltischeck, P.C. (“RMF” ), which RMF has agreed to hold in RMF’s trust account pursuant to a separate letter agreement between RMF and Buyer. Within ten (10) calendar days following the Closing Date, Sellers shall make a written request for (i) one or more endorsements to the PLL Policy permitting and enacting the pre-purchase, for an amount equal to the Insurance Escrow Amount, of a supplemental extended reporting period, such that an extended reporting period shall be in effect beginning on September 19, 2021 and ending on November 19, 2025, and otherwise leaving the terms and conditions of the PLL Policy unchanged (including the policy period), and (ii) an “insured contract endorsement” under the PLL Policy describing this Agreement, and shall take all actions necessary or appropriate to ensure that each such endorsement is validly and effectively issued and obtained. Upon the reasonable request of Sellers, Buyer shall, and shall cause Coram to, cooperate with Sellers in all reasonable respects in connection with such request. Sellers shall provide written notice to Buyer and RMF of such written request, accompanied by written instruction to RMF to disburse to the insurer under the PLL Policy the Insurance Escrow Amount in satisfaction of the additional premium for the endorsement described in clause (i) of this Section 6.09(a). If, for any reason, the Insurance Escrow Amount is insufficient to fully satisfy the additional premium for such endorsement, Sellers shall satisfy such insufficiency by paying the requisite additional amount to the insurer under the PLL Policy in accordance with the insurer’s payment instructions. (b) During the period ending on the fifth anniversary of the Closing Date, Buyer shall cause Coram to maintain (i) the PLL Policy (provided that, following the expiration of the PLL Policy, the continuance of the extended reporting period thereunder shall satisfy Buyer’s obligation hereunder) and (ii) the policy of insurance described in Section 6.09(b) of the Disclosure Schedules (the “Environmental Policy”) (provided that Coram is the first named insured thereunder, the policy term of the Environmental Policy is for no less than five years following the Closing Date, and that Sellers shall have taken all actions necessary to bind coverage under such policy, including the satisfaction of all application and underwriting requirements, and shall have paid the full policy premium for the full policy term of the Environmental Policy), and shall not waive, amend, modify, revise, or apply to the insurer to modify or revise, the PLL Policy or the Environmental Policy (as applicable), or change the broker of record under the PLL Policy or the Environmental Policy (as applicable), in each case in any manner adverse to Sellers, without the written approval of Sellers, which shall not be unreasonably withheld, conditioned or delayed; provided that in no event will Buyer eliminate a Seller or Sellers as named insured, reduce any coverage limit, or otherwise impair the coverage afforded Sellers under the PLL Policy or the Environmental Policy (as applicable). Buyer may increase the coverage limits of the PLL Policy or the Environmental Policy (as applicable) following the Closing in its sole discretion and at its sole cost and expense. For the avoidance of doubt, all costs and expenses associated with the Environmental Policy as of the date of its inception or in connection with its inception (including the full policy premium, any attorneys’ fees or any broker fees or commissions) shall be the responsibility of Sellers. Section 6.10 Termination of Related Party Agreements. Each Contract set forth on, or required to be set forth on, Section 3.08(a)(xv) of the Disclosure Schedules is hereby terminated and of no force and effect as of the Closing. 36 302010047 v18

Section 6.11 401(k) Plan Termination. As promptly as possible following the Closing, Sellers shall (a) submit to the Internal Revenue Service the appropriate application for determination as to the Terminated 401(k) Plan’s qualified status; and (b) deliver copies of and evidence thereof to Buyer. Section 6.12 Bank Account Transition. As promptly as possible following the Closing, Sellers shall take all necessary actions to remove the Companies’ names, taxpayer identification numbers and other identifying information on each of the accounts set forth on Section 3.23 of the Disclosure Schedules, other than the account noted as “Bond Security,” which is the subject of Section 6.08. Following the Closing, Sellers shall promptly pay over to Buyer any Accounts Receivable or other amounts for the account of Buyer or any Company that may be received by Sellers following the Closing, including any such amounts deposited into such bank accounts, in order to more fully carry out the provisions of, and give effect to the purposes and intent of, this Agreement. The parties acknowledge that such bank accounts shall be Excluded Assets for purposes of this Agreement. ARTICLE VII TAX MATTERS Section 7.01 Tax Covenants. (a) Without the prior written consent of Buyer, each Seller (and, prior to the Closing, each Company, their respective Affiliates and their respective Representatives) shall not, to the extent it may affect, or relate to, any Company, make, change or rescind any Tax election, amend any Tax Return or take any position on any Tax Return, take any action, omit to take any action or enter into any other transaction that would have the effect of increasing the Tax liability of Buyer or any Company in respect of any Post-Closing Tax Period. Sellers agree that Buyer is to have no liability for any Tax resulting from any action of any Seller, any Company (to the extent such action occurs prior to the Closing Date or is otherwise based on any action by any Seller on behalf of any Company, except with respect to any action taken by any Seller on behalf of any Company at the direction of Buyer, its Affiliates or any of their respective Representatives), any of Sellers’ Affiliates or any of their respective Representatives, and agree, jointly and severally, to indemnify and hold harmless Buyer (and, after the Closing Date, each Company) against any such Tax. (b) All transfer, documentary, sales, use, stamp, registration, value added and other such Taxes and fees (including any penalties and interest) incurred in connection with this Agreement and the other Transaction Documents (including any real property transfer Tax and any other similar Tax) shall be borne and paid by Sellers when due. Sellers shall, at their own expense, timely file any Tax Return or other document with respect to such Taxes or fees (and Buyer shall cooperate with respect thereto as necessary). (c) Sellers shall prepare, or cause to be prepared, all Tax Returns required to be filed by each Company after the Closing Date with respect to a Pre-Closing Tax Period. Any such Tax Return shall be prepared in a manner consistent with past practice (unless otherwise required by Law) and without a change of any election or any accounting method and shall be submitted by Sellers to Buyer (together with schedules, statements and, to the extent requested by Buyer, supporting documentation) at least thirty (30) days prior to the due date (including extensions) of such Tax Return. If Buyer objects to any item on any such Tax Return, it shall, within fifteen (15) days after delivery of such Tax Return, notify Sellers in writing that it so objects, specifying with particularity any such item and stating the specific factual or legal basis for any such objection. If a notice of objection shall be duly delivered, Buyer and Sellers shall negotiate in good faith and use their reasonable best efforts to resolve such items. If Buyer and Sellers are unable to reach such agreement within ten (10) days after receipt by Sellers of such notice, the disputed items shall be resolved by the Independent Accountant and any determination by the Independent 37 302010047 v18

Accountant shall be final. The Independent Accountant shall resolve any disputed items within twenty (20) days of having the item referred to it pursuant to such procedures as it may require. If the Independent Accountant is unable to resolve any disputed items before the due date for such Tax Return, the Tax Return shall be filed consistently with Buyer’s objections and then, if necessary, amended to reflect the Independent Accountant’s resolution. The costs, fees and expenses of the Independent Accountant shall be borne equally by Buyer and Sellers. The preparation and filing of any Tax Return of any Company that does not relate to a Pre-Closing Tax Period shall be exclusively within the control of Buyer. Section 7.02 No Existing Tax Sharing Agreements. No tax sharing agreements exist (whether written or oral). Section 7.03 Tax Indemnification. (a) Sellers shall jointly and severally indemnify each Company, Buyer and each Buyer Indemnitee and hold them harmless from and against (a) any Loss attributable to any breach of or inaccuracy in any representation or warranty made in Section 3.20; (b) any Loss attributable to any breach or violation of, or failure to fully perform, any covenant, agreement, undertaking or obligation in Article VII; (c) all Pre-Closing Taxes, including, without limitation, all Taxes attributable to the Section 338(h)(10) Elections; (d) all Taxes of any member of an affiliated, consolidated, combined or unitary group of which any Company (or any predecessor of any Company) is or was a member on or prior to the Closing Date by reason of a liability under Treasury Regulation Section 1.1502-6 or any comparable provisions of foreign, state or local Law; and (e) any and all Taxes of any Person imposed on any Company arising under the principles of transferee or successor liability or by contract, relating to an event or transaction occurring before the Closing Date; provided, however, that in the case of clauses (c), (d) and (e) above, Sellers shall not be liable for any Taxes treated as a Liability in the calculation of Trade Working Capital. In each of the above cases, together with any out-of-pocket fees and expenses (including reasonable attorneys’ and accountants’ fees) incurred in connection therewith. Sellers shall reimburse Buyer for any Taxes of any Company that are the responsibility of any Seller pursuant to this Section 7.03 within ten (10) Business Days after payment of such Taxes by Buyer or the applicable Company. (b) The indemnifications provided in this Section 7.03 shall not be subject to any baskets, caps, thresholds, or other limitations. Section 7.04 Straddle Period. In the case of Taxes that are payable by any Company with respect to a taxable period that begins before and ends after the Closing Date (each such period, a “Straddle Period”), the portion of any such Taxes that are treated as Pre-Closing Taxes for purposes of this Agreement shall be: (a) in the case of Taxes based upon, or related to, income or receipts, deemed equal to the amount that would be payable if the taxable year ended with the Closing Date; and (b) in the case of other Taxes, deemed to be the amount of such Taxes for the entire period multiplied by a fraction the numerator of which is the number of days in the period ending on the Closing Date and the denominator of which is the number of days in the entire period. Section 7.05 Contests. Buyer agrees to give written notice to Sellers of the receipt of any written notice by any Company, Buyer or any of Buyer’s Affiliates that involves the assertion of any claim, or the commencement of any Action, in respect of which an indemnity may be sought by Buyer pursuant to this Article VII (a “Tax Claim”); provided, that failure to comply with this provision shall not affect Buyer’s right to indemnification hereunder, unless the indemnifying party is materially prejudiced by Buyer’s failure to provide the aforementioned notice. Buyer shall control the contest or resolution of any Tax Claim; 38 302010047 v18

provided, however, that Buyer shall obtain the prior written consent of Sellers (which consent shall not be unreasonably withheld, conditioned or delayed) before entering into any settlement of a claim or ceasing to defend such claim; and, provided, further, that Sellers shall be entitled to participate in the defense of such claim and to employ counsel of its choice for such purpose, the fees and expenses of which separate counsel shall be borne solely by Sellers. Section 7.06 Cooperation and Exchange of Information. Sellers and Buyer shall provide each other with such cooperation and information as either of them reasonably may request of the other in filing any Tax Return pursuant to this Article VII or in connection with any audit or other proceeding in respect of Taxes of any Company. Such cooperation and information shall include providing copies of relevant Tax Returns or portions thereof, together with accompanying schedules, back-up materials, related work papers and documents relating to rulings or other determinations by a Governmental Authority. Each of Sellers and Buyer shall retain all Tax Returns, schedules and work papers, records and other documents in its possession relating to Tax matters of each Company for any taxable period beginning before the Closing Date until the expiration of the statute of limitations of the taxable periods to which such Tax Returns and other documents relate, without regard to extensions except to the extent notified by the other party in writing of such extensions for the respective Tax periods. Prior to transferring, destroying or discarding any Tax Returns, schedules and work papers, records and other documents in its possession relating to Tax matters of any Company for any taxable period beginning before the Closing Date, Sellers or Buyer (as the case may be) shall provide the other party with reasonable written notice and offer the other party the opportunity to take custody of such materials. Section 7.07 Tax Treatment of Indemnification Payments. Any indemnification payments pursuant to this Article VII and Article VIII shall be treated as an adjustment to the aggregate purchase price for the Securities by the parties for Tax purposes, unless otherwise required by Law. Any such adjustment shall be allocated for Tax purposes to the portion of the aggregate purchase price allocated to the Company whose assets or activities gave rise to such indemnification payment. If it is impracticable to identify such Company, the purchase price adjustment shall be made ratably among the Companies in the same proportions as the original purchase price was allocated among the Securities pursuant to Exhibit G. Section 7.08 Survival. Notwithstanding anything in this Agreement to the contrary, the provisions of Section 3.20 and this Article VII shall survive for the full period of all applicable statutes of limitations (giving effect to any waiver or extension thereof) plus sixty (60) days. Section 7.09 Overlap. To the extent that any obligation or responsibility pursuant to Article VIII may overlap with an obligation or responsibility pursuant to this Article VII, the provisions of this Article VII shall govern and control. Section 7.10 Section 338(h)(10) Elections. At Buyer’s option, in its sole discretion, Sellers shall join in an appropriate and timely manner with Buyer and shall make elections under Section 338(h)(10) of the Code and any corresponding election permitted under any local, state or non-U.S. jurisdiction (collectively, “Section 338(h)(10) Elections” ) with respect to Buyer’s acquisition of the Securities issued by the S Corporations. Sellers shall cooperate with Buyer to take all actions necessary or appropriate to effect and preserve timely Section 338(h)(10) Elections with respect to Buyer’s acquisition of the Securities issued by the S Corporations, including but not limited to participating in the timely filing and execution of Internal Revenue Service Form 8023 and related or comparable forms for state, local or non-U.S. law purposes (collectively, the “Section 338(h)(10) Forms” ). Buyer shall prepare all Section 338(h)(10) Forms (other than sections or such forms that relate to information regarding Sellers) and shall provide the Section 338(h)(10) Forms to Sellers prior to the Closing Date. Sellers shall promptly and properly review, comment on (if needed), complete, execute and deliver to Buyer at the Closing all of the Section 338(h)(10) Forms provided by Buyer. Buyer shall be authorized to complete the Section 338(h)(00) 00 000000000 v18

Forms in accordance with the provisions of this Agreement and file the Section 338(h)(10) Forms with the applicable Governmental Authority. Section 7.11 Purchase Price Allocation. The Purchase Price shall be allocated among the Securities and further allocated among the assets of each Company in accordance with Exhibit G (it being acknowledged that “fair market value” shall be determined by an independent appraisal to be completed by Buyer as promptly as possible following the Closing), and the parties and each of their respective Affiliates shall report the acquisition of Securities and allocation of the Purchase Price among the assets of each Company in a manner consistent with such allocation on all Tax Returns (including IRS Form 8883) and shall not take any position on any Tax Return or during the course of any audit or other proceeding that is inconsistent with Exhibit G unless required by a determination of a Governmental Authority that is final. Within 60 days following the Closing Date, Buyer shall provide to Sellers a schedule that sets forth the fair market value of the assets constituting Class IV and Class V assets of each Company (the “Class IV and V Allocation Schedule”). Sellers shall have 60 days after the Class IV and V Allocation Schedule is delivered to Sellers to review and comment on the Class IV and V Allocation Schedule and identify potential adjustments thereto. If Sellers fail to identify potential adjustments within such 60 day period, the Class IV and V Allocation Schedule shall be deemed accepted. Sellers and Buyer shall work together in good faith to resolve differences with respect to the allocation. To the extent there remains any disagreement between Sellers and Buyer within 15 days after the delivery by the Sellers of proposed adjustments to Buyer’s proposed allocation, (i) each party shall be permitted to file all Tax Returns based on an allocation of value to Class IV, V, VI and VII assets that such party determines in its own discretion, or (ii) Buyer and Sellers may jointly decide to refer the dispute to the Independent Accountant to resolve the dispute and the Independent Accountant shall make within 60 days a final determination binding upon the parties of the appropriate allocation of value to Class IV and Class V assets. Buyer and Sellers shall cooperate with each other to enable the Independent Accountant to render a proper decision. The fees and expenses of the Independent Accountant shall be borne under the same methodology as the fees of the Independent Accountant as set forth Section 2.04(e). Neither Sellers, Buyer, nor any of their respective Affiliates shall take any position (whether in audits, Tax Returns or otherwise) that is inconsistent with such allocation and Exhibit G unless required to do so by applicable Law. The parties shall, as applicable, timely and properly prepare, execute, file and deliver all such documents, forms and other information as the other parties may reasonably request in connection with Exhibit G including the agreed allocation, if any, of value to Class IV and Class V assets. The parties shall promptly advise one another of the existence of any Tax audit, controversy or litigation related to the allocation set forth on Exhibit G. In the event that such allocation is disputed by any Governmental Authority, the party receiving notice of such dispute will promptly notify the other parties and the parties will consult in good faith how to resolve such dispute in a manner as consistent as possible with such allocation. The parties acknowledge that, by reason of the sale and purchase of the outstanding equity interests of MPD LLC, MPD LLC will terminate as a partnership for federal Tax purposes pursuant to situation 2 in Revenue Ruling 99-6. The parties recognize that Buyer’s purchase of the MPD LLC equity interests will be treated for federal income Tax purposes as (a) a sale by Sellers of limited liability company interests, and (b) a purchase by Buyer of MPD LLC’s assets.

(g) Cap and Claims Period — Specified Liability. Notwithstanding anything in this Section 8.04 to the contrary, the aggregate liability of Sellers under Section 8.02(j) shall not exceed $2,000,000. Buyer’s sole recourse with respect to the indemnity provided under Section 8.02(j) shall be to set off, offset and recoup from the Post-Closing Payments any liability for which a Seller is determined to be liable to Buyer or any Affiliate of Buyer pursuant to Section 8.02 related to such matter. Sellers shall not have any liability with respect to any Losses or any claim for indemnification arising out of or relating to such matter unless such Loss or claim is asserted in good faith by written notice of claim specifying the factual basis thereof in reasonable detail (to the extent known at such time) from the Indemnified Party given to the Indemnifying Party on or prior to the second anniversary of the Closing Date. (h) Subject to clauses (k) and (l) of this Section 8.04, each of the limitations on the aggregate liability of Sellers set forth in clauses (d), (e), (f) and (g) of this Section 8.04 shall be separate and independent limitations on the aggregate liability of Sellers under this Article VIII. The limitations on 44 302010047 v18

the aggregate liability of Sellers set forth in clauses (d), (e), (f) and (g) of this Section 8.04 shall not apply to any claims based upon or arising out of any of the Buyer Deductible Exclusions or the Seller Deductible Exclusions. For the avoidance of doubt, the limitations set forth in this Section 8.04 apply to Losses incurred or sustained by, or imposed upon, the Buyer Indemnitees collectively and not individually. (i) The limitations on the liability of Sellers under, and the period in which the Indemnified Party must give written notice asserting a claim or Loss with respect to, Section 8.02(l) shall be governed by the clause(s) of this Section 8.04 applicable to the underlying matter related to such Action. (j) In the event any Company or any of their respective Subsidiaries suffers, incurs or otherwise becomes subject to any Losses as a result of or in connection with any inaccuracy in or breach or alleged breach of any representation, warranty, covenant or obligation, then Buyer shall also be deemed, by virtue of its ownership of the Securities, without duplication to have incurred Losses as a result of and in connection with such inaccuracy or breach. (k) No Buyer Indemnitee shall be entitled to recover for any Loss or claim pursuant to any provision of this Agreement (i) to the extent any Buyer Indemnitee has already recovered such Loss or claim under any other provision of this Agreement or (ii) to the extent that the limitation on the aggregate liability of Sellers applicable to such Loss or claim (as set forth in clauses (d), (e), (f) or (g) of this Section 8.04(k)), if any, has been reached. (l) A Buyer Indemnitee shall only be entitled to recover against Sellers with respect to any individual Loss or claim pursuant to one clause of Section 8.02 (provided that the Environmental Indemnification Provisions shall be deemed to be one clause for this purpose), and the limitation set forth in this Section 8.04 applicable to such clause shall apply to such Loss or claim. By way of example, it is the parties’ intention that a Buyer Indemnitee shall not be entitled to recover with respect to any individual Loss under both Section 8.04(e) (General Environmental Indemnification Matters) and Section 8.04(f) (Landfill Indemnification Matters), but rather under only one such section. (m) No Buyer Indemnitee or Seller Indemnitee shall be entitled to recover any Loss pursuant to any provision of this Agreement to the extent such Loss is agreed by such Buyer Indemnitee or Seller Indemnitee, as applicable, to be, or is determined by final, non-appealable adjudication to be, the direct result of the gross negligence, willful misconduct, criminal activity or willful violation of Law of such Buyer Indemnitee or Seller Indemnitee, as applicable. Except as provided in the immediately preceding sentence, each of Sellers on the one hand and Buyer and the Companies on the other hand waives, and acknowledges and agrees that each such party shall not have and shall not exercise or assert (or attempt to exercise or assert), any right of contribution, right of indemnity or other right or remedy against the other party in connection with any indemnification obligation or any other Liability to which any party may become subject under or in connection with this Agreement or any Transaction Document. (n) For the purposes of this Article VIII, any Losses shall be determined on a net basis after giving effect to any actual cash payments, setoffs, recoupment or any other payments in each case received or retained by the Indemnified Party (including any Insurance Proceeds actually received by the Indemnified Party) as a result of any event giving rise to a claim for such indemnification. Any Insurance Proceeds actually received or paid related to the PLL Policy or the Environmental Policy with respect to a claim based on a General Environmental Indemnification Matter or a Landfill Indemnification Matter (and not later recouped or otherwise required to be returned to the applicable insurer) shall reduce dollar for dollar the applicable limitation set forth in clause (e) or clause (f) of this Section 8.04; provided, however, that for the avoidance of doubt, to the extent any Loss is paid directly by Sellers to a Buyer Indemnified Party, and Insurance Proceeds are received or paid with respect to such Loss, such amount shall only be counted once for purposes of reducing such applicable limitation (by way of example and not limitation, if 45 302010047 v18

a Buyer Indemnitee experiences a $5,000 Loss and receives payment in respect thereof by Sellers, and thereafter the Sellers receive $5,000 of Insurance Proceeds in respect of such Loss, the applicable limitation shall be reduced by $5,000). Any Insurance Proceeds actually received by or paid to Buyer related to the Environmental Policy with respect to a claim that is not an Insured Indemnification Claim (and not later recouped or otherwise required to be returned to the applicable insurer) shall reduce dollar for dollar the applicable limitation set forth in clause (e) or clause (f) of this Section 8.04. If an Indemnified Party receives a payment pursuant to this Article VIII from an Indemnifying Party in respect of any Loss (an “Indemnity Payment” ) and subsequently receives Insurance Proceeds or proceeds from any third party in respect of indemnification for such Loss that actually reduce the amount of such Loss, then the Indemnified Party shall pay to the Indemnifying Party an amount equal to the excess of the Indemnity Payment received by the Indemnified Party over the Indemnified Party’s actual Loss (as so reduced by such Insurance Proceeds or third party proceeds actually received); provided, however, that if any insurance carrier or other third party recoups such Insurance Proceeds or third party proceeds or otherwise requires such Insurance Proceeds or third party proceeds to be returned to such carrier or third party, under a reservation of rights or otherwise, then (i) if the Indemnified Party has paid to the Indemnifying Party such Insurance Proceeds or third party proceeds pursuant to this clause (n) of this Section 8.04, the Indemnifying Party shall promptly pay over such Insurance Proceeds or third party proceeds to the applicable carrier or third party and (ii) if the Indemnified Party has not yet paid to the Indemnifying Party such Insurance Proceeds or third party proceeds, the Indemnified Party shall not be obligated to pay such Insurance Proceeds or third party proceeds to the Indemnifying Party and shall instead return such Insurance Proceeds or third party proceeds to the applicable carrier or third party. (o) The Parties acknowledge that nothing in this Article VIII is intended relieve any obligation of any insurer under the terms of the applicable insurance policy, including any obligation to pay a claim under such policy. In furtherance of the foregoing the applicable Indemnified Party, subject to Section 8.07, shall use commercially reasonable good faith efforts to seek to collect or recover any Insurance Proceeds to which such Indemnified Party is entitled in connection with any Loss for which the Indemnified Party seeks indemnification pursuant to this Article VIII; provided, however, that if the Loss is subject to the Environmental Indemnification Provisions, the applicable Buyer Indemnitee shall only be required to seek to collect or recover Insurance Proceeds under the PLL Policy or the Environmental Policy and not any other insurance policy; and provided, further, that the parties acknowledge that any claims by any Indemnified Party against an Indemnifying Party under this Article VIII are separate and independent from any claims under any applicable insurance policies and that the Indemnifying Party’s obligation to indemnify, defend and hold harmless the Indemnified Party for such Losses is not limited, conditioned or otherwise affected in any way upon any potential or actual recovery under such policies, or any position taken by Sellers, Buyer or any Company with any carrier or other third party in connection with any claims under such policies, or any assistance provided by Sellers, Buyer or any Company in connection with any claims under such policies. (p) The Parties acknowledge that the indemnification rights and obligations of the Parties specifically set forth in this Article VIII are the sole and exclusive indemnification rights of the Parties with respect to the matters set forth in this Article VIII and any matters related thereto and that the Parties expressly disclaim any and all statutory or common law rights of indemnification with respect to the matters set forth in this Article VIII. Section 8.05 Indemnification Procedures. The party making a claim under this Article VIII is referred to as the “Indemnified Party”, and the party against whom such claims are asserted under this Article VIII is referred to as the “Indemnifying Party”. (a) Third Party Claims. If any Indemnified Party receives notice of the assertion or commencement of any Action made or brought by any Person who is not a party to this Agreement or an 46 302010047 v18

Affiliate of a party to this Agreement or a Representative of the foregoing (a “Third Party Claim”) against such Indemnified Party with respect to which the Indemnifying Party is obligated to provide indemnification under this Agreement, the Indemnified Party shall give the Indemnifying Party reasonably prompt written notice thereof, but in any event not later than ten (10) days after receipt of such notice of such Third Party Claim. The failure to give such prompt written notice shall not, however, relieve the Indemnifying Party of its indemnification obligations, except and only to the extent that the Indemnifying Party is prejudiced or forfeits rights or defenses by reason of such failure. Such notice by the Indemnified Party shall (A) describe the Third Party Claim in reasonable detail, (B) in the case of a Third Party Claim against a Buyer Indemnitee, shall specify the applicable clause(s) of Section 8.02 under which such Buyer Indemnitee is claiming indemnification from Sellers and the applicable limitation provision(s) of Section 8.04 related thereto, and (C) shall include copies of all material written evidence thereof and shall indicate the estimated amount, if reasonably practicable, of the Loss that has been or may be sustained by the Indemnified Party. The Indemnifying Party shall have the right to participate in, or by giving written notice to the Indemnified Party within fifteen (15) days of receipt of notice from the Indemnified Party of the commencement of such Third Party Claim, to assume the defense of any Third Party Claim at the Indemnifying Party’s expense and by the Indemnifying Party’s own counsel, and the Indemnified Party shall cooperate in good faith in such defense; provided, however, that the Indemnifying Party shall not be entitled to assume the defense, contest, or prosecute such Third Party Claim, or any portion thereof, if (i) the Third Party Claim, or any portion thereof, relates to any criminal activity or breach of Law or Action with respect thereto, (ii) the Third Party Claim primarily seeks an injunction or non-monetary or equitable relief against the Indemnified Party, (iii) the amount in dispute exceeds the maximum amount for which the Indemnifying Party can then be liable pursuant to this Article VIII in light of the limitations on indemnification contained in this Article VIII, if applicable, and any prior indemnification claims paid or outstanding (unless the Indemnified Party agrees to waive such limitations on indemnification contained in this Article VIII, if applicable, with respect to such dispute), (iv) the Indemnifying Party does not agree in writing that it is obligated to pay all Losses arising from or related to such Third Party Claim subject only to the limitations on indemnification contained in this Article VIII, if applicable, (v) the Indemnifying Party does not, upon assumption thereof in accordance herewith, conduct the defense of such Third Party Claim actively and diligently, (vi) such Third Party Claim includes as the named parties in any such claim both the Indemnifying Party and the Indemnified Party and the Indemnifying Party or the Indemnified Party reasonably determine upon the advice of counsel that representation of both parties by the same counsel would be prohibited by applicable codes of professional conduct, or (vii) the Third Party Claim is asserted directly or indirectly by a customer or supplier, including any Material Customer or Material Supplier, of any Company; provided that the Indemnified Party agrees to consult with the Indemnifying Party in connection with Third Party Claims described in subsections (iii) through (vii) of this Section 8.05(a). In the event that the Indemnifying Party assumes the defense of any Third Party Claim, subject to Section 8.05(b), it shall have the right to take such action as it deems necessary to avoid, dispute, defend, appeal or make counterclaims pertaining to any such Third Party Claim in the name and on behalf of the Indemnified Party. The Indemnified Party shall have the right to participate in the defense of any Third Party Claim with counsel selected by it subject to the Indemnifying Party’s right to control the defense thereof. The fees and disbursements of such counsel shall be at the expense of the Indemnified Party, provided, however, that, if, in the reasonable opinion of counsel to the Indemnified Party, (A) there are legal defenses available to an Indemnified Party that are different from or additional to those available to the Indemnifying Party; or (B) there exists a conflict of interest between the Indemnifying Party and the Indemnified Party that cannot be waived, the Indemnifying Party shall, subject to the provisions of this Article VIII (including Section 8.04 hereof), be liable for the reasonable fees and expenses of one counsel to the Indemnified Party in each jurisdiction where the Indemnified Party determines counsel is reasonably required. If the Indemnifying Party elects not to compromise or defend such Third Party claim, fails to promptly notify the Indemnified Party in writing of its election to defend as provided in this Agreement or fails to actively and diligently prosecute the defense of such Third Party Claim, or is not entitled to assume the defense of (or subsequently fails to be entitled to continue to assume the defense of) such Third Party 47 302010047 v18

Claim, the Indemnified Party may, subject to Section 8.05(b), pay, compromise or defend such Third Party Claim and shall be entitled, subject to the provisions of this Article VIII, to seek indemnification for any and all Losses based upon, arising from or relating to such Third Party Claim (including the advancement of its attorneys’ fees and expenses in defending such Third Party Claim). Sellers and Buyer shall cooperate with each other in all reasonable respects in connection with the defense of any Third Party Claim, including making available pertinent records and other information in the possession or control of the non-defending party relating to such Third Party Claim and furnishing, without expense (other than reimbursement of actual out-of-pocket expenses) to the defending party, management employees of the non-defending party as may be reasonably necessary for the preparation of the defense of such Third Party Claim. (b) Settlement of Third Party Claims. Notwithstanding any other provision of this Agreement, neither the Indemnifying Party nor the Indemnified Party shall enter into settlement or consent to the entry of any judgment with respect to any Third Party Claim without the prior written consent of the other party, which consent shall not be unreasonably withheld, conditioned or delayed, in each case, except as provided in this Section 8.05(b). If a firm offer is made to settle a Third Party Claim without leading to liability or the creation of a financial or other obligation on the part of the Indemnified Party and provides, in customary form, for the unconditional release of each Indemnified Party from all liabilities and obligations in connection with such Third Party Claim and the Indemnifying Party desires to accept and agree to such offer, the Indemnifying Party shall give written notice to that effect to the Indemnified Party. If the Indemnified Party fails to consent to such firm offer within ten (10) days after its receipt of such notice, the Indemnified Party may continue to contest or defend such Third Party Claim and in such event, the maximum liability of the Indemnifying Party as to such Third Party Claim shall not exceed the amount of such settlement offer. If the Indemnified Party fails to consent to such firm offer and also fails to promptly assume defense of such Third Party Claim, the Indemnifying Party may settle the Third Party Claim upon the terms set forth in such firm offer to settle such Third Party Claim. If the Indemnified Party has assumed the defense pursuant to Section 8.05(a), it shall not agree to any settlement without the written consent of the Indemnifying Party (which consent shall not be unreasonably withheld or delayed). (c) Direct Claims. Any Action by an Indemnified Party on account of a Loss that does not result from a Third Party Claim (a “Direct Claim”) shall be asserted by the Indemnified Party giving the Indemnifying Party reasonably prompt written notice thereof, but in any event not later than thirty (30) days after the Indemnified Party becomes aware of such Direct Claim. The failure to give such prompt written notice shall not, however, relieve the Indemnifying Party of its indemnification obligations, except and only to the extent that the Indemnifying Party is prejudiced or forfeits rights or defenses by reason of such failure. Such notice by the Indemnified Party (i) shall describe the Direct Claim in reasonable detail, (ii) in the case of a Direct Claim by a Buyer Indemnitee, shall specify the applicable clause(s) of Section 8.02 under which such Buyer Indemnitee is claiming indemnification from Sellers and the applicable limitation provision(s) of Section 8.04 related thereto, and (iii) shall include copies of all material written evidence thereof and shall indicate the estimated amount, if reasonably practicable, of the Loss that has been or may be sustained by the Indemnified Party. The Indemnifying Party shall have thirty (30) days after its receipt of such notice to respond in writing to such Direct Claim. The Indemnified Party shall allow the Indemnifying Party and its professional advisors to investigate the matter or circumstance alleged to give rise to the Direct Claim, and whether and to what extent any amount is payable in respect of the Direct Claim and the Indemnified Party shall assist the Indemnifying Party’s investigation by giving such information and assistance (including access to the Companies’ premises and personnel and the right to examine and copy any accounts, documents or records) as the Indemnifying Party or any of its professional advisors may reasonably request. If the Indemnifying Party does not so respond within such thirty (30) day period, the Indemnifying Party shall be deemed to have rejected such claim, in which case the Indemnified Party shall be free to pursue such remedies as may be available to the Indemnified Party on the terms and subject to the provisions of this Agreement. 48 302010047 v18

Section 8.06 Payments. Once a Loss is agreed to by the Indemnifying Party or finally adjudicated to be payable pursuant to this Article VIII, the Indemnifying Party shall satisfy its payment obligations under this Article VIII within fifteen (15) Business Days of such agreement or final, non- appealable adjudication by wire transfer of immediately available funds; provided, however, that in the case of a claim (i) under Section 8.02(a) with respect to any Losses or any claim for indemnification arising out of any inaccuracy in or breach of any representation or warranty in the Environmental Representation or (ii) under Section 8.02(f) (collectively, the “Environmental Indemnification Provisions” ), if a Buyer Indemnitee has submitted a claim regarding such Loss to the applicable carrier under the PLL Policy, the Environmental Policy, or both, and such Buyer Indemnitee has elected to have Sellers control such claim, Sellers shall satisfy their payment obligations within ninety (90) calendar days of such agreement or non- appealable adjudication by wire transfer of immediately available funds; provided, further, that the receipt of any insurance proceeds by any Indemnifying Party shall not be a condition to such Indemnifying Party’s payment obligations under this Section 8.06. The parties agree that should a Indemnifying Party not make full payment of any such obligations within such fifteen (15) Business Day or ninety (90) calendar day period, as applicable, any amount payable shall accrue interest from and including the date of agreement of the Indemnifying Party or final, non-appealable adjudication to and including the date such payment has been made at a rate per annum equal to the Reference Rate. Such interest shall be calculated daily on the basis of a 365 day year and the actual number of days elapsed, without compounding. If an Indemnifying Party breaches its obligation to pay any amount hereunder, the Indemnified Party may, in addition to any other rights or remedies it may have, proceed against any securities, payments or other property, directly or indirectly, owned by or owed to any member or shareholder, as applicable, of the Indemnifying Party, including, with respect to Sellers, any securities, payments, or other property owned or owed under any other Transaction Document, and the Indemnifying Party shall take any and all actions, including granting any powers of attorney, stock transfer powers, or other authorizations amending any Contracts, to permit such recourse. Section 8.07 Insured Claims. An Indemnified Party shall provide prompt written notice to the Indemnifying Party of any claim submitted by it to an insurance carrier, including a claim submitted under the PLL Policy or the Environmental Policy, related to a matter subject to indemnification under this Agreement and of any Insurance Proceeds related thereto. With respect to any claim submitted to the applicable carrier under the PLL Policy, the Environmental Policy, or both, based on any Losses subject to Seller’s obligations under the Environmental Indemnification Provisions (an “Insured Indemnification Claim”), provided that Sellers have agreed in writing that they are obligated to pay for all such Losses, subject only to the limitations on indemnification contained in this Article VIII, a Buyer Indemnitee may elect, by delivering to Sellers a timely notice that a claim has been submitted to the applicable carrier under the PLL Policy, the Environmental Policy, or both, which notice includes such election, to have Sellers control such claim for insurance coverage under the PLL Policy and/or the Environmental Policy (as applicable) on behalf of all named insureds under the PLL Policy and/or the Environmental Policy (as applicable), and in such event, (i) Sellers shall actively and diligently pursue such claim under the PLL Policy and/or the Environmental Policy (as applicable) at Sellers’ expense, (ii) Sellers shall not settle or consent to any judgment with respect to such claim without Buyer’s prior written consent, not to be unreasonably withheld, conditioned or delayed, and (iii) Buyer shall, and shall cause its Affiliates (including Coram) to, cooperate with Sellers in all reasonable respects in connection with such claim, including making available pertinent records and other information in the possession or control of and furnishing, without expense (other than reimbursement of actual out-of-pocket expenses) to Sellers, employees of Buyer, in each case as may be reasonably necessary for the pursuit of such claim. If (A) the applicable Buyer Indemnitee has not elected to have Sellers control a claim under the PLL Policy, the Environmental Policy, or both, and (B) in the case of a Insured Indemnification Claim, Sellers have agreed in writing that they are obligated to pay for all such Losses underlying an Insured Indemnification Claim, subject only to the limitations on indemnification contained in this Article VIII, then Buyer and Coram shall have the exclusive right, on behalf of all named insureds under such policies (including Sellers), to control any claim 49 302010047 v18

made against the PLL Policy or the Environmental Policy, whether such claim is an Insured Indemnification Claim or otherwise, and shall have the right, in its sole and absolute discretion, to take all such actions as it deems necessary with respect to such claim, and to make any and all determinations regarding the timing of such claim, the amount of such claim, the timing and amount of any settlement, or any other matter related to the claim process; provided that Buyer and Coram (i) shall, in the case of an Insured Indemnification Claim, pursue such claim against the PLL Policy and/or the Environmental Policy (as applicable) actively, diligently and in good faith, and shall use commercially reasonable efforts to maximize Insurance Proceeds with respect to such claim, taking into account the relative costs of pursuing such Insurance Proceeds, the potential magnitude of recovery (if determinable), the likelihood of success of such efforts, and whether any Losses incurred in connection with such efforts would exceed the applicable limitations on Sellers’ liability under Section 8.04, (ii) shall not settle or consent to any judgment with respect to an Insured Indemnification Claim without Sellers’ prior written consent, not to be unreasonably withheld, conditioned or delayed; and (iii) copy Sellers on all correspondence and submissions related to such claims. Notwithstanding the foregoing, during the period beginning on the Closing Date and ending on the date that Sellers are no longer liable under the Environmental Indemnification Provisions, Buyer shall not, and shall cause its Affiliates and Representatives not to, make any claim against the PLL Policy with respect to any matter that is not an Insured Indemnification Claim or a claim with respect to Losses arising from an Emerging Contaminant. The parties acknowledge that the PLL Policy and the Environmental Policy are or may be subject to various limitations, including retrospectively-rated premiums, deductibles, self-insured retentions, retentions, insurer insolvencies, impairment, erosion, exhaustion, and various settlements and/or releases that may impose defense, indemnification or any other obligations on Seller, Buyer or the Companies. The parties further acknowledge that, if any named insured’s assertion of insurance rights under any policy of insurance in accordance with this Agreement gives rise, directly or indirectly, to any obligations imposed on the Sellers, Buyer, any Company or any of their respective Affiliates, including any costs, expenses, attorneys’ fees, deductibles, self-insured retentions, retentions or retrospectively-rated premiums, or to any defense, indemnity or hold harmless obligations related to insurance settlement(s), such obligations shall be considered Losses subject to the applicable obligations of Sellers under Section 8.02 (in cases where any Buyer Indemnitee is the Indemnified Party) or Buyer under Section 8.03 (in cases where any Seller Indemnitee is the Indemnified Party), as the case may be. ARTICLE IX MISCELLANEOUS Section 9.01 Expenses. Except as otherwise expressly provided herein, all costs and expenses, including fees and disbursements of counsel, Representatives, financial advisors, accountants and other professional service providers, incurred in connection with this Agreement and the transactions contemplated hereby shall be paid by the party incurring such costs and expenses, whether or not the Closing shall have occurred. Notwithstanding the foregoing, the parties acknowledge that Buyer is responsible for, and has paid, the entire cost of any filing required to be made on behalf of Buyer, Sellers or the Companies pursuant to the HSR Act in connection with the transactions contemplated hereby. Section 9.02 Notices. All notices, requests, consents, claims, demands, waivers and other communications hereunder shall be in writing and shall be deemed to have been given (a) when delivered by hand (with written confirmation of receipt); (b) when received by the addressee if sent by a nationally recognized overnight courier (receipt requested); (c) on the date sent by facsimile or e-mail of a PDF document (with confirmation of transmission) if sent during normal business hours of the recipient, and on the next Business Day if sent after normal business hours of the recipient; or (d) on the fifth day after the date mailed, by certified or registered mail, return receipt requested, postage prepaid.

For purposes of this Agreement, (a) the words “include,” “includes,” “including” or any variation thereof shall be deemed to be followed by the words “without limitation” and shall not be construed to limit any general statement that it follows to the specific or similar items or matters immediately following it; (b) the word “or” is not exclusive; and (c) the words “herein,” “hereof,” “hereby,” “hereto” and “hereunder” refer to this Agreement as a whole. Unless the context otherwise requires, references herein: (x) to Articles, Sections, Schedules and Exhibits mean the Articles and Sections of, and Schedules and Exhibits attached to, this Agreement; and (y) to an agreement, instrument or other document means such agreement, instrument or other document as amended, supplemented and modified from time to time to the extent permitted by the provisions thereof. References to any Laws shall be deemed to include any and all rules and regulations promulgated thereunder and shall refer to such Laws, rules and regulations as amended from time to time and any successor legislation thereto (for the avoidance of doubt, with respect to any representations or warranties related to compliance with any Law, such representation or warranty shall be made as to the Law in effect as of the date such representation or warranty is made). Any reference in this Agreement to gender shall include all genders, and words imparting the singular number shall include the plural and vice versa. This Agreement shall be construed without regard to any presumption or rule requiring construction or interpretation against the party drafting an instrument or causing any instrument to be drafted. The Schedules and Exhibits referred to herein shall be construed with, and as an integral part of, this Agreement to the same extent as if they were set forth verbatim herein. Items and matters disclosed in the Disclosure Schedules are organized to correspond only to the sections of this Agreement to which the matters relate and shall not qualify any other provisions of this Agreement. The parties intend that each representation, warranty and covenant contained herein will have independent significance. If any party has breached any representation, warranty or covenant contained herein in any respect, the fact that there exists another representation, warranty or covenant relating to the same subject matter (regardless of the relative levels of specificity) that such party has not breached will not detract from or mitigate the fact that the party is in breach of the other representation, warranty or covenant. The specification of any dollar amount or the inclusion of any item in the representations and warranties contained in this Agreement or the Disclosure Schedules or any exhibits attached to this Agreement shall not be deemed to establish a threshold for materiality or to establish the standard for whether a particular act or agreement is within or outside the Ordinary Course of Business for purposes of this Agreement. When calculating the period of time before which, within which or following which any act is to be done or step taken pursuant to this Agreement, the date that is the reference date in calculating such period shall be excluded. If the last day of such period is a non-Business Day, the period in question shall end on the next succeeding Business Day. As used in this Agreement, the word “day” shall mean a calendar day and not a Business Day. With respect to all dates and time periods set forth or referred to in this Agreement, time is of the essence. For purposes of determining the existence of an inaccuracy in any representations or warranties, the failure of any representations or warranties to be true and correct, the breach of any covenants or agreements and calculating Losses hereunder, any materiality, Material Adverse Effect, or similar qualifications in the representations, warranties, covenants and agreements shall be excluded from, given no effect and be otherwise disregarded. Section 9.04 Headings. The headings in this Agreement are for reference only and shall not affect the interpretation of this Agreement. 52 302010047 v18

Section 9.05 Severability. If any term or provision of this Agreement is invalid, illegal or unenforceable in any jurisdiction, such invalidity, illegality or unenforceability shall not affect any other term or provision of this Agreement or invalidate or render unenforceable such term or provision in any other jurisdiction. Except as provided in Section 6.02(e), upon such determination that any term or other provision is invalid, illegal or unenforceable, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in a mutually acceptable manner in order that the transactions contemplated hereby be consummated as originally contemplated to the greatest extent possible. Section 9.06 Entire Agreement. This Agreement and the other Transaction Documents constitute the sole and entire agreement of the parties to this Agreement with respect to the subject matter contained herein and therein, and supersede all prior and contemporaneous understandings and agreements, both written and oral, with respect to such subject matter.
