The Accounting Arbitrator shall resolve all remaining Disputed Items in accordance herewith within twenty (20) Business Days following the date of its designation. In connection with the foregoing, the Accounting Arbitrator shall be instructed to and must (i) limit its determination(s) only to the remaining Disputed Items, (ii) make its determination(s) as to each remaining Disputed Item in accordance with Section 1.2(c), Section 1.2(e), Section 1.2(f) and Section 1.2(g) and (iii) not assign a value to any remaining Disputed Item greater than the highest value for such Disputed Item claimed by either the Purchaser or the Sellers or less than the lowest value for such Disputed Item claimed by either the Purchaser or the Sellers. All determinations by the Accounting Arbitrator shall be final and binding upon the parties for purposes of this Section 1.3, absent fraud or manifest error. The fees and expenses of the Accounting Arbitrator shall be borne by the party(ies) based on the degree (as determined by the Accounting Arbitrator) to which the Accounting Arbitrator has accepted the positions of the Purchaser and the Sellers.

(c) At such time as the Adjusted Closing Net Working Capital shall become final in accordance with Section 1.3(b) (the “Final Adjusted Closing Net Working Capital”), the Final Adjusted Closing Net Working Capital shall be compared to the Estimated Adjusted Closing Net Working Capital. At such time as the Closing Net Debt shall become final in accordance with Section 1.3(b) (the “Final Closing Net Debt”), the Final Closing Net Debt shall be compared to the Estimated Closing Net Debt. At such time as the Project Capital Expenditure Amount shall become final in accordance with Section 1.3(b) (the “Final Project Capital Expenditure Amount”), the Final Project Capital Expenditure Amount shall be compared to the Estimated Project Capital Expenditure Amount. At such time as the Ferrybridge Capital Expenditure Amount shall become final in accordance with Section 1.3(b) (the “Final Ferrybridge Capital Expenditure Amount”), the Final Ferrybridge Capital Expenditure Amount shall be compared to the Estimated Ferrybridge Capital Expenditure Amount.

(d) In the event that the Final Adjusted Closing Net Working Capital exceeds the Estimated Adjusted Closing Net Working Capital, the Purchaser shall be obligated to pay to the Sellers an amount equal to such excess, in cash in immediately available funds. In the event that the Estimated Closing Net Debt exceeds the Final Closing Net Debt, the Purchaser shall be obligated to pay to the Sellers an amount equal to such excess, in cash in immediately available funds. In the event that the Final Project Capital Expenditure Amount exceeds the Estimated Project Capital Expenditure Amount, the Purchaser shall be obligated to pay to the Sellers an amount equal to such excess, in cash in immediately available funds.

(e) In the event that the Estimated Adjusted Closing Net Working Capital exceeds the Final Adjusted Closing Net Working Capital, the Sellers shall be obligated to pay to the Purchaser an amount equal to such excess, in cash in immediately available funds. In the event that the Final Closing Net Debt exceeds the Estimated Closing Net Debt, the Sellers shall be obligated to pay to the Purchaser an amount equal to such excess, in cash in immediately available funds. In the event that the Estimated Project Capital Expenditure Amount exceeds the Final Project Capital Expenditure Amount, the Sellers shall be obligated to pay to the Purchaser an amount equal to such excess, in case in immediately available funds.

(f) In the event that the Estimated Ferrybridge Capital Expenditure Amount exceeded the Target Ferrybridge Capital Expenditure Amount, then:

(i) in the event the Target Ferrybridge Capital Expenditure Amount exceeds the Final Ferrybridge Capital Expenditure Amount, the Purchaser shall (x) be obligated to pay the Sellers pursuant to Section 1.3(h) an amount equal to the Ferrybridge Closing Decrease and (y) be obligated to pay the amount by which the Target Ferrybridge Capital Expenditure Amount exceeds the Final Ferrybridge Capital Expenditure Amount in equal monthly installments beginning on the fifth (5^th) day after final determination and ending with the monthly installment payment in June 2015; or

(ii) in the event the Final Ferrybridge Capital Expenditure Amount exceeds the Target Ferrybridge Capital Expenditure Amount and:

(x) the Estimated Ferrybridge Capital Expenditure Amount exceeds the Final Ferrybridge Capital Expenditure Amount, then the Purchaser shall be obligated to pay the Sellers pursuant to Section 1.3(h) an amount equal to the difference between the Estimated Ferrybridge Capital Expenditure Amount and the Final Ferrybridge Capital Expenditure Amount; or

(y) the Final Ferrybridge Capital Expenditure Amount exceeds the Estimated Ferrybridge Capital Expenditure Amount, then the Sellers shall be obligated to pay the Purchaser pursuant to Section 1.3(h) an amount equal to the difference between the Final Ferrybridge Capital Expenditure Amount and the Estimated Ferrybridge Capital Expenditure Amount.

(g) In the event that the Target Ferrybridge Capital Expenditure Amount exceeded the Estimated Ferrybridge Capital Expenditure Amount, then:

(i) in the event the Target Ferrybridge Capital Expenditure Amount exceeds the Final Ferrybridge Capital Expenditure Amount, the Purchaser shall be obligated to pay the amount by which Target Ferrybridge Capital Expenditure Amount exceeds the Final Ferrybridge Capital Expenditure Amount in equal monthly installments beginning on the fifth (5^th) day after final determination and ending with the monthly installment payment in June 2015; or

(ii) in the event the Final Ferrybridge Capital Expenditure Amount exceeds the Target Ferrybridge Capital Expenditure Amount, then the Sellers shall be obligated to pay the Purchaser pursuant to Section 1.3(h) an amount equal to the difference between the Final Ferrybridge Capital Expenditure Amount and the Target Ferrybridge Capital Expenditure Amount.

(h) The payment obligations under Section 1.3(d), Section 1.3(e), Section 1.3(f) and Section 1.3(g) shall be combined or offset as applicable to determine the payor, payee and amount of adjustment payment to be paid. The Sellers and the Purchaser acknowledge and agree that any payment made pursuant to this Section 1.3(h) shall be paid within five (5) days after final determination (except with respect to any adjustment pursuant to Section 1.3(f)(i)(y) or Section 1.3(g)(i)) and will be treated as an adjustment to the Purchase Price for income tax purposes to the extent permitted by Law.

(i) During the period that the Sellers and their advisors and representatives are conducting their review of the Purchaser’s preparation of the Adjusted Closing Net Working Capital Statement, the Closing Net Debt Statement, the Project Capital Expenditure Statement and the Ferrybridge Capital Expenditure Statement, the Sellers and their advisors and representatives will have reasonable access during normal business hours to the Books and Records of the Transferred Companies and the work papers (subject, in the case of such work papers prepared by the Purchaser’s or Transferred Companies’ auditors, to the Sellers entering into such waivers, indemnities and other agreements as reasonably required by such auditors) prepared by or on behalf of the Purchaser and its representatives in connection with the Purchaser’s preparation of the Adjusted Closing Net Working Capital Statement, the Closing Net Debt Statement, the Project Capital Expenditure Statement and the Ferrybridge Capital Expenditure Statement, in each case to the extent reasonably relevant to the calculation of Final Adjusted Closing Net Working Capital, Final Closing Net Debt, Final Project Capital Expenditure Amount and Final Ferrybridge Capital Expenditure Amount.

The WM Parent has full corporate power and authority to execute and deliver the WM Guarantee. The execution, delivery and performance by the WM Parent of the WM Guarantee and the consummation by the WM Parent of the transactions contemplated thereby have been duly and validly authorized by all necessary corporate action. The WM Guarantee constitutes the legal, valid and binding

obligations of the WM Parent enforceable against the WM Parent in accordance with its terms, except as enforceability may be limited by applicable bankruptcy, insolvency, reorganization, fraudulent conveyance, fraudulent transfer, moratorium or similar laws affecting the enforcement of creditors’ rights generally and by general principles of equity relating to enforceability (regardless of whether considered in a proceeding at law or in equity), and no event has occurred which, with or without notice, lapse of time or both, would constitute a default on the part of the WM Parent under the WM Guarantee.

ARTICLE IV

CERTAIN TAX MATTERS

Section 4.1 Allocation of Liability for Taxes. The Sellers shall be liable for, and pursuant to Article IX shall indemnify and hold harmless the Purchaser Indemnified Parties from and against, any and all Indemnified Amounts with respect to (i) Income Taxes of any Person for which the Transferred Companies are liable with respect to any Pre-Closing Tax Period, including Income Taxes with respect to a Post-Closing Tax Period attributable to Tax Partnerships, and Subpart F income, recognized in a Pre-Closing Period as set forth in Section 4.2(b) and (c) and including (for the avoidance of doubt) Income Taxes resulting from the Spin-Off, (ii) Income Taxes for which the Transferred Companies are liable with respect to a Post-Closing Tax Period that are (A) the result of an audit adjustment made by a Tax authority, and (B) attributable to the adjustments to depreciation and amortization expense (and related adjustments to adjusted tax basis of assets) made by the Sellers and their Affiliates during the 2009-2013 Tax years, and (iii) Income Taxes of the Sellers or any of their Affiliates (other than the Transferred Companies) with respect to any taxable period. For purposes of determining the Sellers’ liability under this Section 4.1, the parties’ liability for a payment of any other amounts with respect to Taxes under Article IX and the parties’ liability for the payment of any other Indemnified Amounts with respect to Taxes under any other provision of this Agreement, if any accrued Taxes are included as a current asset or liability of the Transferred Companies for purposes of computing the Final Adjusted Closing Net Working Capital, the parties will have satisfied their obligation pay such Taxes to the extent of such accrual. Provided that the Purchaser has complied with the requirement of Section 4.3(c)(ii), the Sellers shall pay or cause to be paid to the applicable Transferred Company or Transferred Companies an amount equal to the Taxes for which the Sellers are liable under this Section 4.1 and/or Article IX in connection with any Tax Return (other than a Tax Return of a Seller Affiliated Group) with respect to a Pre-Closing Tax Period or a Straddle Period that is filed after the Closing Date. Such payment shall be made no later than three (3) Business Days prior to the date that such Tax Return that is filed in accordance with Section 4.3. The Seller shall pay all Taxes due in connection with any Tax Return of a Seller Affiliated Group that is filed after the Closing Date to the appropriate Tax Authority in a timely manner.

Section 4.2 Straddle Period; Partnerships; Subpart F Income.

(a) In the case of any Straddle Period, the amount of all Taxes of the Transferred Companies attributable to the Pre-Closing Tax Period shall (a) in the case of any Taxes based on or measured by net income or gross receipts of the Transferred Companies, and any Income Taxes imposed in connection with a sale or other disposition of property or other specifically identifiable transaction or event, be determined based on an interim closing of the books as of the close of business on the Closing Date (provided

that any exemptions, allowances, and deductions that are calculated on an annual basis shall be apportioned between the period ending on the Closing Date and the period after the Closing Date based on the number of days in each such period), and (b) in the case of any other Income Taxes (including but not limited to Income Taxes in the nature of franchise Taxes determined on the basis of taxable capital or assets), be deemed to be the product of the amount of such Income Taxes for the entire Straddle Period multiplied by a fraction, the numerator of which shall be the number of days in the portion of the Straddle Period ending on and including the Closing Date and the denominator of which shall be the total number of days in the entire Straddle Period. The Sellers and the Purchaser each hereby acknowledge and agree that, to the extent permitted by Law, employee bonus payments associated with the transactions contemplated by this Agreement paid or accrued by the Transferred Companies on or before the Closing Date, shall be allocated to (and treated as incurred during) the Pre-Closing Tax Period.

(b) In the case of any entity (each such entity, a “Tax Partnership”) treated as a partnership for U.S. federal or state Income Tax purposes that is owned (directly or indirectly) by a Transferred Company, Income Taxes attributable to the Pre-Closing Tax Period shall include any U.S. federal and state Income Taxes of a Transferred Company for a tax period (or portion thereof) beginning after the Closing Date that are attributable to allocations of taxable income recognized by a Tax Partnership in a Pre-Closing Tax Period. Where practical, such taxable income shall be determined by using the “closing of the books” method for the Tax Partnership, and where that is not practical, the taxable income of the Tax Partnership for the tax year that includes the Closing Date shall be apportioned between the Pre-Closing Tax Period and the Post-Closing Tax Period based on the relative number of days in such period.

(c) If and to the extent that any Transferred Company recognizes in a Post-Closing Tax Period income that constitutes “subpart F income” within the meaning of Section 952 of the Code that arose in a Pre-Closing Tax Period, the U.S. federal and state Income Taxes resulting from such taxable income inclusion shall be treated as Income Taxes with respect to a Pre-Closing Tax Period.

Section 4.3 Preparation and Filing of Tax Returns.

(a) The Sellers’ Rights and Responsibilities. The Sellers shall timely prepare and file, or cause to be timely prepared and filed, on behalf of the Transferred Companies (i) all Tax Returns of any Seller Affiliated Group, (ii) all other Income Tax Returns with respect to Income Taxes for which the Sellers are liable under Section 4.1 hereof (other than Tax Returns for Straddle Periods and Tax Returns for Post-Closing Tax Periods reporting Income Taxes described in clause (ii) of Section 4.1 hereof) and (iii) any other Tax Returns that are due (taking into account extensions) prior to the Closing Date.

(b) Purchaser’s Rights and Responsibilities. The Purchaser shall timely prepare and file, or cause to be timely prepared and filed, on behalf of the Transferred Companies all Tax Returns other than those described in Section 4.3(a) and related documentation required under the Tax Law for any Post-Closing Tax Period, including (but only to the extent not described in Section 4.3(a)) all Income Tax Returns for all Straddle Periods and other Tax Returns that are due (taking into account extensions) on or after the Closing Date.

(i) The Sellers shall, on the one hand, and the Purchaser and the Transferred Companies shall, on the other hand, prepare and provide to the other party such Tax information as is reasonably requested by the other party to enable the other party to prepare any Tax Return that such other party has the right and obligation hereunder to prepare and file.

(ii) The Sellers shall, on the one hand, and the Purchaser shall, on the other hand, with respect to any Tax Return (other than a Tax Return of a Seller Affiliated Group) which such party is responsible hereunder for preparing and filing, or causing to be prepared and filed, make such Tax Return and related workpapers available for review by the other party if the Tax Return (i) is with respect to Taxes for which the other party or one of its Affiliates may be liable hereunder or under applicable Tax Law, or (ii) claims Tax benefits which the other party or one of its Affiliates is entitled to receive hereunder. The filing party shall use reasonable best efforts to make Tax Returns available for review as required under this Section 4.3(c)(ii) sufficiently in advance of the due date for filing such Tax Returns to provide the non-filing party with a meaningful opportunity to analyze and comment on such Tax Returns and have such Tax Returns modified before filing and shall consider in good faith any comments provided in writing by the non-filing party before filing.

(d) Consistency of Filing and Accounting Methods. Any Tax Return that includes or is based on the operations, ownership, assets or activities of the Transferred Companies for any Pre-Closing Tax Period (other than a Tax Return of a Seller Affiliated Group) shall be prepared in accordance with past Tax accounting and filing practices used with respect to the Tax Return in question (unless otherwise required by applicable Tax Law).

Section 4.4 Refunds of Taxes; Amended Returns.

(a) Refunds. If the Purchaser receives an Income Tax refund with respect to Taxes that were (i) paid by the Transferred Companies prior to the Closing Date, (ii) paid or indemnified by the Sellers or (iii) specifically included as a current liability in Adjusted Closing Net Working Capital, and in each case, such refund was neither (x) specifically included as a current asset in Adjusted Closing Net Working Capital nor (y) attributable to losses, credits or other Tax attributes that were generated after the Closing, then, the Purchaser shall pay, within thirty (30) days following the receipt of such Tax refund, the amount of such Tax refund (net of any Taxes or other reasonable costs and expenses incurred in connection with the receipt of, or the claiming of, such refund) to the Sellers. If the Sellers receive a Tax refund that (A) relates to Taxes for which the Purchaser is liable hereunder, (B) was specifically included as a current asset in Adjusted Closing Net Working Capital or (C) is attributable to losses, credits or other Tax

attributes that were generated after the Closing, then the Sellers shall pay, within thirty (30) days following the receipt of such Tax refund, the amount of such Tax refund (net of any Taxes or other reasonable costs and expenses incurred in connection with the receipt of, or the claiming of, such refund) to the Purchaser. In either case, to the extent that any such Tax refund is subsequently disallowed or required to be repaid by a Governmental Authority, then the Sellers or the Purchaser, as applicable, shall promptly repay to the other the amount of such refund (plus any interest, penalties or additions to Tax imposed by a Governmental Authority in connection therewith).

(b) Amended Tax Returns. Any amended Income Tax Return or claim for Income Tax refund shall be filed, or caused to be filed, only by the party that was originally responsible for preparing and filing the Tax Return being amended or on which the Taxes claimed as a refund were originally reported; provided, however, that such party shall not, without the prior written consent of the other party (which consent shall not be unreasonably withheld or delayed), make or cause to be made any such filing to the extent that such filing, if accepted, reasonably might change the Tax liability of the other party for any Tax period; provided, further, that the party that was not originally responsible for preparing and filing the relevant Tax Return may file, or cause to be filed, such an amended Tax Return or claim for Tax refund with the prior written consent of the party that was so originally responsible (which consent shall not be unreasonably withheld or delayed). Notwithstanding anything to the contrary herein, the Sellers shall control any audits and proceedings related to all Tax Returns filed by a Seller Affiliated Group, provided that the Sellers shall keep the Purchaser reasonably informed regarding the status of any such audit or proceeding to the extent that it could affect the Taxes or Tax Returns of a Transferred Company for a Post-Closing Tax Period.

Section 4.5 Tax Controversies; Audit Adjustments; Assistance and Cooperation.

(a) Notice. In the event any Tax authority informs the Sellers, on the one hand, or the Purchaser or the Transferred Companies, on the other hand, of any notice of proposed audit, claim, assessment or other dispute concerning an amount of Taxes with respect to which the other party may incur liability hereunder, the party so informed shall promptly notify the other party in writing of such matter. Such notice shall contain factual information (to the extent known) describing any asserted Tax liability in reasonable detail and shall be accompanied by copies of any notice or other documents received from any Tax authority with respect to such matter. The failure by a party to provide such notice shall not limit any rights or obligations hereunder with respect to indemnification, except to the extent that the indemnifying party is actually prejudiced by such failure.

(b) Control Rights. The Sellers shall control any audits, disputes, or administrative, judicial or other proceedings related solely to Income Taxes for Pre-Closing Tax Periods or other Taxes for Pre-Closing Tax Periods which the Sellers would be required to indemnify the Purchaser (including, for the avoidance of doubt, any audit, dispute or proceeding related to Income Taxes of a Seller Affiliated Group), and the Purchaser shall control any other Tax audits, disputes or administrative, judicial or other proceedings. Subject to the preceding sentence, in the event an adverse determination

may result in each party having responsibility for an amount of Taxes under this Article IV, each party shall be entitled to fully participate in that portion of the proceedings relating to the Taxes with respect to which it may incur liability hereunder. For purposes of this Section 4.5(b), the term “participate” shall include (i) participation in conferences, meetings or proceedings with any Tax authority, the subject matter of which includes an item for which such party may have liability hereunder, (ii) participation in appearances before any court or tribunal, the subject matter of which includes an item for which such party may have liability hereunder, and (iii) with respect to matters described in the preceding clauses (i) and (ii), participation in the determination of the content of the documentation, protests, memoranda of fact and law, and briefs, and in the content and conduct of oral arguments and presentations.

(i) The Sellers’ Audit Adjustments. In the event that (i) a final determination is made by a Governmental Authority which results in an adjustment to the Tax items reported on a Tax Return filed with respect to a Pre-Closing Period (including that portion of a Straddle Period for which a Seller is liable for Taxes hereunder), and (ii) that adjustment creates a corresponding adjustment (or adjustments) that either reduces the taxable income or increases the amount of any Tax credit reported on a Tax Return filed with respect to a Post-Closing Tax Period (including that portion of a Straddle Period for which the Purchaser is liable for Taxes hereunder), then assuming the Sellers have complied with their obligations pursuant to this Article IV, the Purchaser shall pay to the Sellers an amount equal to any Tax Benefit derived by the Purchaser (or any Affiliate thereof) related to such corresponding adjustment (or adjustments). Such payment shall be made no later than thirty (30) days after the date of such final determination.

(ii) The Purchaser’s Audit Adjustments. In the event that (i) a final determination is made by a Governmental Authority which results in an adjustment to the Tax items reported on a Tax Return filed with respect to a Post-Closing Tax Period (including that portion of a Straddle Period for which the Purchaser is liable for Taxes hereunder), and (ii) that adjustment creates a corresponding adjustment (or adjustments) that either reduces the taxable income or increases the amount of any Tax credit reported on a Tax Return filed with respect to a Pre-Closing Period (including that portion of a Straddle Period for which a Seller is liable for Taxes hereunder), then the Sellers shall pay to the Purchaser an amount equal to any Tax Benefit derived by the Sellers (or any Affiliate thereof) related to such corresponding adjustment (or adjustments). Such payment shall be made no later than thirty (30) days after the date of such final determination.

(d) Assistance and Cooperation. The Sellers, on the one hand, and the Purchaser and the Transferred Companies, on the other hand, shall cooperate (and cause their employees, agents and Affiliates to cooperate) with each other and each other’s agents, including accounting firms and legal counsel, as reasonably requested in

connection with Tax matters relating to the Transferred Companies. The parties shall retain all Tax Returns, schedules and workpapers, and all material records and other documents relating thereto, until the expiration of the applicable statute of limitations (including, to the extent notified by any party, any extension thereof) of the Tax period to which such Tax Returns and other documents and information relate. Any information or documents provided under this Section 4.5(d) shall be kept confidential by the party receiving such information or documents, except as may otherwise be reasonably necessary in connection with the filing of Tax Returns or in connection with administrative or judicial proceedings relating to Taxes.

Section 4.6 Certain Taxes. One half of all transfer, documentary, sales, stamp, registration and other similar Taxes and fees (including any penalties and interest) incurred in connection with this Agreement shall be borne by the Purchaser and one half of all such Taxes, fees, penalties and interest shall be borne by the Sellers; except for any transfer, documentary, sales, stamp, registration and other similar Taxes and fees (including any penalties and interest) incurred in connection with the Spin-Off or in connection with the transactions contemplated by Section 6.19, which shall be borne by the Sellers.

Section 4.7 Relationship to Section 3.8 and Article IX. Any indemnification obligations described in this Article IV shall be subject to, and made in the manner described in, Article IX of this Agreement; provided, however, that the procedures set forth in this Article IV shall apply notwithstanding anything to the contrary set forth in Section 9.3 hereof. In the case of any indemnity claim for Taxes that arises out of both the obligations set forth in this Article IV and a breach of the representations and warranties described in Section 3.8, the rights and obligations of the parties hereto shall be governed by this Article IV; provided, however, that this Section 4.7 shall not limit an Indemnified Party’s right to also recover amounts representing Indemnified Amounts (including reasonable attorneys’ fees and court costs), subject to the limitations described in Article IX.

ARTICLE V

CERTAIN UNDERSTANDINGS AND AGREEMENTS OF THE PARTIES

Section 5.1 Consents. The Sellers shall use their reasonable best efforts to procure, and the Purchaser shall use its reasonable best efforts to assist the Sellers in procuring, all consents, novations, approvals or waivers, in a form reasonably satisfactory to the Purchaser, which are required under applicable Law or the terms of any Material Agreement to consummate the transactions contemplated by this Agreement (including the Spin-Off); provided that neither party shall be obligated to make any payments to third parties or undertake any obligations in connection with the procurement of such consents (other than as expressly provided pursuant to Section 6.19 and Section 6.20) and the Sellers and the Purchaser acknowledge and agree that, other than those consents and approvals set forth on Schedule 7.1(g) and Schedule 7.2(g), its receipt of any such consents, novations, approvals or waivers is not a condition to its obligation to consummate the transactions contemplated hereby.

Section 5.2 Notice of Environmental Claims. The Sellers shall give prompt written notice to the Purchaser of the commencement after the date hereof of any material Environmental Claim, or inspection of any Transferred Company or any assets or property of

any Transferred Company, by any Governmental Authority with responsibility for enforcing or implementing any applicable Environmental Laws, and provide to the Purchaser such information as the Purchaser may reasonably request regarding such Environmental Claim, any developments in connection therewith, and, as applicable, any responses thereto.

Section 5.3 Public Statements. The parties hereto shall consult with each other prior to issuing any press release or any written public statement with respect to this Agreement or the transactions contemplated hereby and shall not issue any such press release or written public statement without the other parties’ prior written consent (which shall not be unreasonably withheld, conditioned or delayed), except for any public disclosure which the Purchaser or the Sellers in good faith believe is required by Law (in which case the disclosing party will consult with the other party prior to making such disclosure); provided, however, that Purchaser and its Affiliates may, without the prior consent of the Sellers, issue any non-public release or statement or otherwise disclose information with respect to this Agreement, other transaction documents or the transactions (including the Purchase Price and other terms of the Agreement or other transaction documents) to any of its or their respective Affiliates, Purchaser Representatives, Lenders and current and potential investors, in each case, which are subject to contractual confidentiality obligations with respect to the information disclosed to them (whether pursuant to such release or statement or otherwise). Similarly, notwithstanding the foregoing, the Sellers and their Affiliates may, without the prior consent of the Purchaser, disclose information with respect to this Agreement, other transaction documents or the transactions contemplated hereby (including the Purchase Price and other terms of the Agreement or other transaction documents) to any of its or their respective Affiliates, accountants, counsel, financial advisors and other representatives, in each case, which are subject to confidentiality obligations with respect to the information disclosed to them.

Section 5.4 Compliance with WARN Act. The Purchaser agrees that it will not, and will cause its Affiliates not to, cause any of the employees of the Transferred Companies to suffer an “employment loss” for purposes of the WARN Act if such employment loss would create, or would reasonably be expected to create, any liability for the Sellers under the WARN Act or any similar state or local applicable law. The Purchaser and its Affiliates shall be responsible for all liabilities under the WARN Act and any similar state or local Legal Requirement solely resulting from (a) the Closing and/or (b) from the actions of the Purchaser and its Affiliates following the Closing. Upon the Purchaser’s written request, the Sellers shall advise the Purchaser of the number of employee terminations at each facility of the Transferred Companies that have occurred during the ninety (90)-day period prior to the Closing Date.

Section 5.5 No Solicitation; Alternative Transactions. From the date hereof until the earlier of (a) the valid termination of this Agreement pursuant to Article VIII and (b) the Closing Date, neither the Sellers nor the Company shall, and the Sellers and the Company shall cause their Affiliates, including the WM Parent, and representatives not to, directly or indirectly, encourage, solicit, participate in or initiate discussions or negotiations with, or provide any information to, or enter into any agreement or understanding with, any Person or group (other than any party hereto or any Affiliate, associate or designee of any party hereto) concerning any proposal for the sale, merger, combination, joint venture or other transaction involving all or any part of the Business and properties of the Transferred Companies.

Section 6.4 Financing.

(b) Prior to the Closing, the Purchaser shall give the Sellers prompt (and in any event, within three (3) Business Days) written notice: (i) of any default or breach (or any event that, with or without notice, lapse of time or both, would reasonably be expected to give rise to any default or breach) by any party to the Commitment Letters or definitive documents related to the Financing of which the Purchaser or its Affiliates becomes aware, (ii) of the receipt of any written notice or other communication from any party (other than the Purchaser) to a Commitment Letter with respect to any (A) actual or potential default, breach, termination or repudiation by any party to a Commitment Letter or any definitive document related to the Financing or any provisions of a Commitment Letter or any definitive document related to the Financing or (B) significant dispute or disagreement between or among any parties to a Commitment Letter or any definitive document related to the Financing, (iii) if for any reason the Purchaser has reasonably determined in good faith that it will not be able to obtain all or any portion of the Financing on the terms, in the manner or from the sources contemplated by the Commitment Letters (including the flex provisions), and (iv) subject to Section 6.4(c) and 6.4(d) below, of any amendment, modification or replacement of any Commitment Letter with copies thereof. As soon as reasonably practicable, but in any event, within three (3) Business Days following delivery by the Sellers to the Purchaser of written request therefor, the Purchaser shall provide any information reasonably requested by the Sellers relating to any circumstance referred to in the immediately preceding sentence.

(c) Except as permitted by Section 6.4(d), prior to the Closing, the Purchaser shall not, without the prior written consent of the Sellers, permit any amendment or modification to be made to, or consent to any waiver of any provision or remedy under, the Commitment Letters, if such amendment, modification or waiver (i) reduces the aggregate amount of the Financing contemplated in the Commitment Letters below the amount that, together with any other equity contributions or alternative financings effected and Purchaser’s cash on hand, is sufficient to consummate the transactions contemplated by this Agreement (including by changing the amount of fees to be paid or the original issue discount of the Debt Financing), (ii) imposes new or additional conditions or otherwise expands, amends or modifies any of the conditions to the receipt of the Financing in a manner materially adverse to the Purchaser or the Transferred Companies, or (iii) amends or modifies any other term of a Commitment Letter in a manner that would reasonably be expected to (x) delay in any material respect or prevent the Closing (provided that no delay, regardless of materiality, shall be permitted if it would extend the Closing beyond the Termination Date) or (y) materially adversely impact the ability of the Purchaser to enforce its rights against the other parties to the Commitment Letters. Notwithstanding anything to the contrary herein, the Purchaser may, at any time prior to Closing terminate the Debt Commitment Letter and enter into arrangements for any Alternate Debt Financing (as defined below), so long as such Alternate Debt Financing and any New Debt Commitment Letter in respect thereof meets

Any reference in this Agreement to (x) “Debt Financing” shall include the financing contemplated by the Debt Commitment Letter as amended or modified in compliance with this Section 6.4(c), and (y) “Debt Commitment Letter” shall include such document as amended or modified in compliance with this Section 6.4(c).

(d) Prior to the Closing, other than as permitted in Section 6.4(c), if any portion of the Debt Financing becomes unavailable on the terms and conditions contemplated in the Debt Commitment Letter, the Purchaser shall use its reasonable best efforts to arrange promptly to obtain alternative financing from alternative sources in an amount sufficient to consummate the transactions contemplated by this Agreement, on any terms and conditions, provided that such terms and conditions taken as a whole would not be reasonably expected to materially delay or prevent the Closing (provided that no delay, regardless of materiality, shall be permitted if it would extend the Closing beyond the Termination Date) (the “Alternate Debt Financing”), and to obtain a new financing commitment letter with respect to such Alternate Debt Financing (together with any related fee letter, the “New Debt Commitment Letter”) which shall replace the existing Debt Commitment Letter, a true, complete and correct copy of which shall be provided by the Purchaser to the Sellers promptly and in any event, within two (2) Business Days after the execution thereof by the parties to the New Debt Commitment Letter. If any New Debt Commitment Letter is obtained by the Purchaser, any reference in this Agreement to (i) Debt Financing shall mean the debt financing contemplated by the Debt Commitment Letter as modified, amended, supplemented, restated or replaced by the New Debt Commitment Letter, and shall include any Alternate Debt Financing, (ii) “Debt Commitment Letter” shall include the Debt Commitment Letter as modified, amended, supplemented, restated or replaced by the New Debt Commitment Letter, and (iii) “Lenders” shall mean the lenders and other financing sources providing the Debt Financing (as modified by clause (i) above), including the parties to the Debt Commitment Letter or the New Debt Commitment Letter, as applicable, and any definitive agreements related thereto.

(e) The Purchaser shall refrain from taking, directly or indirectly, any action that would reasonably be expected to result in the failure of any of the conditions contained in the Commitment Letters or any definitive agreement relating to the Financing. The Purchaser acknowledges and agrees that the obtaining of the Financing or any Alternate Debt Financing is not a condition to the Closing and reaffirms its obligation to consummate the transactions contemplated by this Agreement irrespective and independently of the receipt of the Financing or the availability of the Financing or any Alternate Debt Financing, or the completion of any such borrowing, subject to the applicable conditions set forth in Section 7.1 and Section 7.2.

(f) The Company and the Sellers shall and shall cause the other Transferred Companies (and its and their respective applicable senior management, personnel and advisors) to cooperate and provide such information reasonably requested by the Purchaser or the Lenders in connection with the arrangement, placement or completion of the Debt Financing, including (i) providing the Purchaser, any Lender, or any Affiliates of any such Person or any of their respective stockholders, members, partners, managers,

officers, directors, employees, agents, advisors, representatives, successors or permitted assigns who have a need to know such information in connection with the transactions contemplated hereby, with financial and other information in the Company’s or the Sellers’ possession, including all financial statements, financial data, audit reports and other information of the type reasonably requested by the Purchaser, (ii) reasonable participation in meetings, presentations, and sessions with rating agencies, (iii) providing reasonable assistance with respect to the preparation of materials for ratings agency presentations, bank information memoranda and similar documents, in each case, including public and private versions of such documents (to the extent applicable) and in connection with the marketing, syndication and arrangement of, and/or satisfying the conditions to, the Debt Financing, and (iv) providing all documentation and other information about the Transferred Companies as is reasonably requested in writing at least 3 Business Days prior to the Closing Date in connection with the Debt Financing and relating to applicable “know your customer” and anti-money laundering rules and regulations, including the USA PATRIOT Act.

(g) The Company shall deliver to the Purchaser the interim financial statements consisting of an unaudited combined balance sheet of the Transferred Companies as at the end of, and related statement of income of the Transferred Companies for, each fiscal quarter (other than the fourth fiscal quarter of any fiscal year) of the Transferred Companies subsequent to March 31, 2014 no later than forty-five (45) days following the conclusion of such quarterly reporting period, in each case prepared in accordance with GAAP and accompanied by a certification from an officer of the Transferred Companies reasonably acceptable to the Purchaser that such financial statements fairly present, in all material respects, the financial condition of the Transferred Companies as of the dates thereof and the results of such Transferred Companies’ operations for the periods covered thereby except for the absence of footnotes disclosures and year-end adjustments (such information, the “Requested Information”). Upon request from the Purchaser, the Sellers shall provide the Purchaser with monthly internal financial information of the Company (which, for clarity of purpose, will not necessarily represent the Transferred Companies on a combined basis) as soon as available following the conclusion of each calendar month, which financial information shall be in the form regularly prepared by the Company.

Section 6.5 Notification of Certain Matters. The Sellers and the Purchaser agree to give prompt notice to each other of, and to use their respective reasonable best efforts to prevent or promptly remedy, (a) the occurrence or failure to occur or the impending or threatened occurrence or failure to occur, of any event which occurrence or failure to occur would be likely to cause any of its representations or warranties in this Agreement to be untrue or inaccurate in any material respect such that (i) in the case of notification by the Purchaser to the Sellers, the Sellers’ condition to Closing set forth in Section 7.1(b), and (ii) in the case of notification by the Sellers to the Purchaser, the Purchaser’s condition to Closing set forth in Section 7.2(b), could reasonably be expected not to be satisfied as of the Closing Date, and (b) any material failure (or any failure in the case of any covenant, condition or agreement containing any materiality qualification) on its part to comply with or satisfy any covenant, condition or agreement to be complied with or satisfied by it hereunder such that (A) in the case of notification by the Purchaser to the Sellers, the Sellers’ condition to Closing set forth in Section 7.1(a), and (B) in

Further, the Sellers and the Purchaser agree to give prompt notice to each other once all their conditions to close set forth in Section 7.1 and Section 7.2 (other than those conditions that by their nature are to be satisfied at the Closing), respectively, have been satisfied or waived.

Section 6.7 Transferred Company Indemnification.

(a) From and after the Closing Date, the Purchaser and the Company shall, jointly and severally, and shall cause the other Transferred Companies to, jointly and severally, indemnify and hold harmless, and advance expenses as incurred to, in each case to the fullest extent permitted under applicable Law, each Person who from and after the Closing is a director, officer, employee, member, manager or representative of any Transferred Company (collectively, the “Transferred Company Indemnified Parties”) in a manner consistent with the terms and conditions on which indemnification is provided for as of the date hereof against any costs, expenses (including reasonable attorneys’ fees), judgments, fines, losses, claims, damages, liabilities and amounts paid in settlement (collectively, “Costs”) incurred in connection with any claim, action, suit, proceeding or investigation, whether civil, criminal, administrative or investigative, arising out of or related to such Transferred Company Indemnified Parties’ service as a director, officer, member or manager of the Transferred Companies or services performed by such Persons at the request of the Transferred Companies at or prior to the Closing Date, whether asserted or claimed prior to, at or after the Closing Date, including, for the avoidance of doubt, in connection with actions to enforce this provision; provided that the Person to whom Costs are advanced provides a reasonable and customary undertaking to repay such Costs if it is ultimately determined that such Person is not entitled to indemnification.

(b) From and after the Closing Date, the Company shall maintain, and the Purchaser and Company shall cause the other Transferred Companies to maintain in effect the provisions in their Organizational Documents to the extent they provide for indemnification, advancement and reimbursement of expenses and exculpation of Transferred Company Indemnified Parties, as applicable, with respect to facts or circumstances occurring at or prior to the Closing Date, on the same basis as set forth in the Organizational Documents of the Company and the other Transferred Companies in effect on the date of this Agreement (true and complete copies of which have been provided or made available to the Purchaser), to the fullest extent permitted from time to time by applicable Law, which provisions shall not be amended except as required by applicable Law or to make changes permitted by applicable Law that would enlarge the scope of the Transferred Company Indemnified Parties’ indemnification rights thereunder.

(c) The covenants contained in this Section 6.7 are intended to be for the irrevocable benefit of and to grant third-party rights to, and shall be enforceable by, each of the Transferred Company Indemnified Parties and their respective heirs and legal representatives and shall not be deemed exclusive of any other rights to which a Transferred Company Indemnified Party is entitled, whether pursuant to Law, contract or otherwise and shall be binding on all successors and assigns of the Purchaser and, subsequent to the Closing, the Company. The obligations of Purchaser under this Section 6.7 shall not be terminated or modified in such a manner as to adversely affect any Transferred Company Indemnified Party unless the affected Transferred Company Indemnified Party shall have consented in writing to such termination or modification. It is expressly agreed that each Transferred Company Indemnified Party shall be a third-party beneficiary of this Section 6.7, and entitled to enforce the covenants contained in this Section 6.7. If any Transferred Company Indemnified Party makes any claim for indemnification or advancement of expenses under this Section 6.7 that is denied by the Purchaser and/or any Transferred Company, and a court of competent jurisdiction determines that the Transferred Company Indemnified Party is entitled to such indemnification, then the Purchaser shall or shall cause the applicable Transferred Company to pay such Transferred Company Indemnified Party’s reasonable costs and expenses, including reasonable legal fees and expenses, incurred in connection with pursuing such claim against the Purchaser and/or applicable Transferred Company. The rights of the Transferred Company Indemnified Parties under this Section 6.7 shall be in addition to, and not in substitution for, any rights such Transferred Company Indemnified Parties may have under the Organizational Documents of any of Transferred Companies or under any applicable contracts, insurance policies or Laws.

On or prior to the Closing Date, the Sellers shall cause to be delivered to the Purchaser duly executed resignations and releases, in the forms attached hereto as Exhibit E, effective as of the Closing, of those officers and directors of the Transferred Companies set forth on Schedule 6.8.

Section 6.9 Replacement of Seller Credit Enhancements; Bridged Seller Guarantees.

(a) Subject to the Purchaser’s requirement to obtain the return or release of the Material WM Guarantees at Closing pursuant to Section 1.5(b)(iv), and except for those guarantees set forth on Schedule 6.9(a)(i) (the “Bridged Seller Guarantees”) which shall be permitted to remain outstanding after the Closing (subject to and in accordance with Section 6.9(d)), the Purchaser shall provide no later than thirty (30) days after Closing substitute Credit Support to the beneficiaries of the Credit Support provided by any WM Company of the obligations of the Transferred Companies described in Schedule 6.9(a)(ii) (the “Scheduled Seller Credit Enhancements”), in order to facilitate the release and return of such Scheduled Seller Credit Enhancements on or within thirty (30) days after the Closing Date. In addition, in the event that following the date hereof the parties discover, or any WM Company provides, any Credit Support of the obligations of the Transferred Companies in addition to (i) the Bridged Seller Guarantees or (ii) the Scheduled Seller Credit Enhancements (such additional Credit Support collectively, the “Unscheduled Seller Credit Enhancements” and, together with the Scheduled Seller Credit Enhancements, the “Seller Credit Enhancements”), the Sellers shall provide the Purchaser with notice thereof. The Purchaser will use its reasonable best efforts to have all such Seller Credit Enhancements released and returned to the Sellers by the date that is thirty (30) days following the Closing Date or, with respect to an Unscheduled Seller Credit Enhancement, a date that is thirty (30) days following the delivery by the Sellers of notice of an Unscheduled Seller Credit Enhancement, if such date is later than thirty (30) days following the Closing Date (the “Return Date”); provided, however, that (x) after the date hereof and prior to Closing, the WM Companies shall not provide Credit Support for the obligations of the Transferred Companies in addition to the Bridged Seller Guarantees or the Scheduled Seller Credit Enhancements in excess of $5,000,000 in the aggregate and (y) the Purchaser shall have no obligation to replace any Unscheduled Seller Credit Enhancements in an aggregate amount in excess of $5,000,000, in the case of (x) and (y), unless the Purchaser otherwise agrees in writing.

(b) The Purchaser shall provide information to the Sellers regarding the status of such replacement and return efforts either (x) upon the Sellers’ reasonable request or (y) upon the date that is fifteen (15) days prior to the Return Date to the extent that certain Seller Credit Enhancements have not yet been released and returned to the Sellers.

(c) If any Seller Credit Enhancement that is not a guarantee has not been returned to the Sellers by the Return Date (an “Unreturned Seller Credit Enhancement”), the Purchaser and the Company shall promptly (but in no event more than five (5) Business Days after the Return Date) cause a “back-to-back” letter of credit and/or bond, as applicable, to be issued in favor of, and naming as beneficiary, the WM Companies providing the Unreturned Seller Credit Enhancement in an amount equal to the aggregate amount of each applicable Unreturned Seller Credit Enhancement. Such amount of such back-to-back letter of credit or bond may be reduced upon and to the extent the obligations covered by such Seller Credit Enhancement have been terminated or reduced as acknowledged by the counterparty.

(d) The Purchaser shall (i) from and after the Closing Date, provide audited financial statements of the Company and the other Transferred Companies, (ii) from and after the date hereof, coordinate with the Sellers and the Company to offer a guaranty or guarantees from the Company and the other Transferred Companies to the beneficiaries of the Bridged Seller Guarantees in replacement, or for the return, of such Bridged Seller Guaranties, and (iii) from and after the date hereof, otherwise use its reasonable best efforts to obtain the return of the Seller Credit Enhancements and Bridged Seller Guarantees from the beneficiaries thereof until such time that the underlying obligations secured by such Seller Credit Enhancements and Bridged Seller Guarantees are terminated or otherwise expire. From and after the date hereof (including after the Closing) the Sellers shall reasonably cooperate with the Purchaser with respect to the replacement or return of the Seller Credit Enhancements and Bridged Seller Guaranties (provided that, for the avoidance of doubt, Sellers shall not be required to make any payment, incur any out-of-pocket cost or otherwise increase its exposure in connection with this cooperation). If any Bridged Seller Guarantee set forth on Schedule 6.9(d) (the “Material Bridged Guarantees”) remains outstanding six (6) months after the Closing Date (the “Grace Period”), the Purchaser and the Company shall pay the Sellers a credit support fee for each day that any such Material Bridged Guarantee is outstanding after such six (6) month period in an amount equal to (1) the Bridged Guarantee Amount for such Material Bridged Guarantee multiplied by (2) the Credit Factor relating to such Material Bridged Guaranty multiplied by (3) the greater of (x) 2.5 % per annum or (y) with respect to any portion of the Bridged Guarantee Amounts, a per annum rate equal to WM Parent’s per annum Letter of Credit Cost under its credit facility with the lowest Letter of Credit Cost then in effect for such portion of the Material Bridged Guarantees for which there is no remaining capacity under a credit facility with a lower Letter of Credit Cost (in the case of this clause (y), only from and after the date on which the Sellers have provided to Purchaser reasonable documentation evidencing such Letter of Credit Cost and only for the period during which such Letter of Credit Cost are in excess of 2.5% per annum), which credit support fee will be payable quarterly in arrears, beginning with the first full quarterly period after the Grace Period until the Material Bridged Guarantee is returned or released back to the Sellers and with each quarterly payment due on or before the fifth (5^th) business day after the end of the applicable quarterly period (the “Bridged Guarantee Support Payment”). To the extent WM Parent’s per annum Letter of Credit Cost is then in excess of 2.5% per annum, the Sellers shall provide Purchasers with prompt notice of any decrease in WM Parent’s per annum Letter of Credit Cost below 2.5% per annum.

(e) Without limiting the foregoing, (i) the Scheduled Seller Credit Enhancements, Bridged Seller Guarantees and any Unscheduled Seller Credit Enhancements (other than Unscheduled Seller Credit Enhancements in excess of $5,000,000 in the aggregate without the approval of the Purchaser) related to any Transferred Company shall be returned to the Sellers upon the earlier to occur of (A) six (6) years after the Closing Date or (B) a Change of Control of such Transferred Company (whether directly or as a result of the Change of Control of the Purchaser or the

Company), and (ii) from and after the Closing, the Purchaser and the Company shall not amend, extend or otherwise modify, or allow any of the Transferred Companies to amend, extend or otherwise modify, the terms of the underlying obligations of the Company or such Transferred Companies under agreements secured by any Seller Credit Enhancements or Bridged Seller Guarantees (other than the exercise by a counterparty of its extension rights under any Specified Extension Agreement pursuant to the terms of such Specified Extension Agreement), until such Seller Credit Enhancement or Bridged Seller Guarantee, as applicable, is returned and replaced to the Sellers. The Purchaser and the Company shall (x) bear all costs and expenses incurred in connection with the replacement and return, or providing back-up Credit Support to a WM Company, of the Seller Credit Enhancements or Bridged Seller Guarantees; (y) reimburse the Sellers for all costs, premiums, fees and other expenses paid or incurred by any WM Company with respect to issuing, providing or maintaining any Unreturned Seller Credit Enhancement; and (z) reimburse, indemnify and hold harmless the Seller Indemnified Parties for all Indemnified Amounts resulting from any draw or claim with respect to the Seller Credit Enhancements or the Bridged Seller Guarantees.

(f) In the event that six (6) years after the Closing Date any Material Bridged Guaranty remains outstanding, then the Bridged Guarantee Support Payment applicable to such Material Bridged Guarantee payable by the Purchaser and the Company (including any successor or assigns) following such time shall be increased by a multiple of three times.

Section 6.10 Payoff Letters. At least six (6) Business Days prior to the Closing Date, the Sellers shall deliver to the Purchaser (A) copies of instructions provided by, or on behalf of, the Sellers in accordance with the terms of the instruments, documents and agreements governing the applicable Terminated Debt for purposes of either terminating, redeeming or defeasing and redeeming, as the case may be, such applicable Terminated Debt and (B) copies of executed payoff or instruction letters, in form and substance reasonably satisfactory to the Purchaser (such instructions and payoff letters are collectively referred to in this Section 6.10 as the “Payoff Letters”), from the applicable debt providers (or agents or trustees therefor) in respect of the Terminated Debt that (W) confirm the aggregate outstanding amount required to be paid or irrevocably deposited to fully satisfy, redeem, defease or discharge such applicable Terminated Debt in accordance with the terms of the applicable indenture, agreement and related documents governing such Terminated Debt as of the anticipated Closing Date (and the daily per diem accrual of interest and premium, if applicable, thereafter) (the “Payoff Amount”), (X) provide that upon receipt or (pursuant to the terms of any applicable Terminated Debt) deposit in irrevocable escrow of the applicable Payoff Amount, such Terminated Debt shall be terminated, defeased or redeemed, as the case may be, except for (aa) contingent indemnification obligations (to the extent no claims thereon have been made as of the Closing Date) which by their terms survive the termination of such Terminated Debt or (bb) any applicable defeasance or escrow provisions (to the extent provided for in the applicable indentures as of the date hereof) with respect to the Terminated Debt, provided that the Terminated Debt shall have been defeased and the liens of the Terminated Debt discharged as of the Closing, and (Y) provide that (i) all liens and any applicable guarantees or letters of credit granted in connection with such Terminated Debt shall be, upon the payment or deposit in escrow of the Payoff Amount at the Closing, automatically released, terminated and discharged and (ii) the Transferred Companies,

The Sellers shall be responsible for all costs, expenses, fees and other amounts payable in connection with the Payoff Amount and shall provide confirmations that all Terminated Debt has been either fully paid and settled or defeased and discharged prior to or upon Closing.

Subject to any WARN Act liabilities allocated pursuant to Section 5.4, neither the foregoing nor any other provision of this Agreement shall constitute a commitment, undertaking or other obligation on behalf of Purchaser or the Company to continue the employment of such Continued Employee for any period of time, and all Continued Employees shall be “at will” employees of the Company (unless applicable law determines otherwise) whose employment may be terminated at any time subject to applicable agreements, if any, of particular Continued Employees with respect to severance or other rights in connection with termination of employment.

(g) The provisions of this Section 6.11 are for the sole benefit of the parties to this Agreement and nothing herein, express or implied, is intended or shall be construed to confer upon or give to any person (including any Participant), other than the parties hereto and their respective permitted successors and assigns, any legal or equitable or other rights or remedies under or by reason of any provision of this Agreement. Nothing contained herein, express or implied, (i) shall be construed to establish, amend, or modify any benefit plan, program, agreement or arrangement; or (ii) shall alter or limit the Sellers’ or the Purchaser’s ability to amend, modify or terminate any benefit plan, program, agreement or arrangement; or (iii) is intended to confer upon any person (including any Participant) any right to any particular term or condition of employment.

The Sellers and the Purchaser each agree that from time to time after the Closing Date and at the prior written request of the other party and without further consideration, they will execute and deliver such further instruments, provide such materials and information and take such other action, as may be reasonably necessary to carry out the purpose and intent of this Agreement with respect to the Closing.

Section 6.13 Termination of Certain Agreements. All contracts or agreements between any Transferred Company, on the one hand, and any WM Company, on the other hand (the “Affiliate Contracts”) (other than the Transition Services Agreement, the Waste Supply Agreements and the Continuing Agreements), shall be terminated immediately prior to the Closing such that there will be no remaining liabilities, obligations, restrictions or payments from, to or between any Transferred Company and any WM Company with respect to such terminated Affiliate Contracts as of the Closing.

Section 6.14 Intercompany Accounts. At or prior to the Closing, the Sellers shall cause to be settled, repaid or cancelled all intercompany accounts between any Transferred Company, on the one hand, and any WM Company, on the other hand, without any post-Closing liability (except for those accounts related to Affiliate Contracts to the extent included in the calculation of Adjusted Closing Net Working Capital or Closing Net Debt).

Section 6.15 Insurance.

(a) The Purchaser shall be solely responsible for providing insurance to each Transferred Company and the Business after the Closing. The Sellers shall maintain or cause to be maintained in full force and effect the material insurance policies (or renewals thereof) covering each Transferred Company and the Business until the Closing. Without limiting the rights of the Purchaser set forth elsewhere in this Agreement, if any claims

may reasonably be made relating to acts, omissions, events or circumstances that have occurred or are existing prior to the Closing Date that relate to any of the Transferred Companies or the Business, and such claims may be made against occurrence based insurance policies of any WM Company, then the Sellers (on behalf of themselves and each other WM Company) shall, at the Purchaser’s request and at the Purchaser’s sole cost and expense, including any deductibles and self-retention amounts (which costs and expenses shall be reimbursed to the Sellers, as incurred), use their reasonable best efforts to permit the Purchaser (after the Closing Date and in cooperation with the Sellers) to file, notice and otherwise continue to pursue such claims under the terms of such policies, and, subject to all of the foregoing, the Sellers (on behalf of themselves and each other WM Company) agree (at the Purchaser’s sole cost and expense, including any deductibles and self-retention amounts) to otherwise reasonably cooperate with the Purchaser or any applicable Transferred Company to make the benefits of any such insurance policies available to the Purchaser or any applicable Transferred Company. Nothing herein shall alter the right of a party to control a Third Party Claim pursuant to Section 9.3.

(b) Subject to any applicable legal restrictions, for a period of five (5) years from and after the Closing Date, the Sellers shall cooperate (and shall cause its employees, agents and the WM Companies to cooperate) with the Purchaser and the Transferred Companies with all loss history or other reasonably necessary insurance underwriting information that the Purchaser may need associated with each Transferred Company or the Business. Such cooperation shall include making information and documents in its possession available to the Purchaser and assisting, at the Purchaser’s sole cost and expense, the Purchaser in compiling the information necessary to fulfill such insurance underwriting request.

Section 6.16 Risk of Loss. Except as otherwise provided in this Section 6.16, during the period between the date hereof and the Closing (the “Interim Period”) all risk of loss or damage to the property or assets of the Transferred Companies shall, as between the Purchaser and the Sellers, be borne by the Sellers. If during the Interim Period the property or assets of the Transferred Companies are damaged by fire or other casualty (each such event, an “Event of Loss”), or are taken by a Governmental Authority by exercise of the power of eminent domain (each, a “Taking”), then the following provisions of this Section 6.16 shall apply:

(a) Following the occurrence of (i) any one or more Events of Loss, if the aggregate costs to restore, repair or replace the property or assets of the Transferred Companies subject to such Event of Loss to a condition reasonably comparable to their prior condition, plus the net present value calculated at the Discount Rate of any lost profits reasonably expected to accrue after Closing as a direct result of such Event of Loss, such amount pursuant to this clause (i) to be determined by an independent third party appraiser mutually selected by the Parties (collectively, “Restoration Costs”) and/or (ii) any one or more Takings, if the value of the property subject to such Taking plus the net present value calculated at the Discount Rate of any lost profits reasonably expected to accrue after Closing as a direct result of such Event of Loss, less any condemnation award received by the Purchaser (provided that any such condemnation award is made available to the Purchaser), such amount pursuant to this clause (ii) to be determined by

an independent third party appraiser mutually selected by the Parties (collectively, the “Condemnation Value”), is, in the aggregate, less than or equal to 1.5% of the Initial Purchase Price, there shall be no effect on the transactions contemplated hereby, including any reduction in the Purchase Price, or the parties’ respective obligations to consummate the purchase and sale contemplated by this Agreement.

(b) Subject to the termination right of the Purchaser and the Sellers set forth in clause (c) below, upon the occurrence of any one or more Events of Loss and/or Takings involving aggregate Restoration Costs and Condemnation Value in excess of 1.5% of the Initial Purchase Price (a “Major Loss”), the Sellers shall have, in the case of a Major Loss relating solely to one or more Events of Loss, the option, exercised by notice to the Purchaser, to restore, repair or replace the damaged assets or properties prior to Closing to a condition reasonably comparable to their prior condition. If the Sellers elect to so restore, repair or replace the assets or properties relating to a Major Loss, which election shall be made by notice to the Purchaser prior to the Closing Date and as soon as practicable following the occurrence of such Major Loss, the Sellers will complete or cause to be completed the repair, replacement or restoration of the damaged assets or property prior to the Closing and the Closing Date shall be postponed for the amount of time reasonably necessary to complete the restoration, repair or replacement of such property or assets as reasonably agreed among the Purchaser and the Sellers (including, if necessary, the extension of the Termination Date contemplated by Section 8.1 to allow for the restoration, repair or replacement of such assets or properties). If the Sellers elect not to cause the restoration, repair or replacement of the property or assets affected by a Major Loss, or such Major Loss is the result in whole or in part of one or more Takings or is otherwise not capable of being restored, repaired or replaced, then the provisions of Section 6.16(c) will apply.

(c) Subject to the termination right of the Purchaser and the Sellers set forth in clause (d) below, in the event that the Sellers elect not to cause the restoration, repair or replacement of a Major Loss, or in the event that the Sellers, having elected to cause repair, replacement or restoration of the Major Loss, fail to cause its completion within the period of time agreed upon by the Parties pursuant to Section 6.16(b) (subject to extension for up to 90 days for causes beyond the Sellers’ control), or in the event that a Major Loss is the result in whole or in part of one or more Takings or is otherwise not capable of being restored, repaired or replaced, then the Parties shall, within 30 days following the Sellers’ election not to cause the restoration, repair or replacement, failure to complete, or the occurrence of such Major Loss, as the case may be, adjust the Initial Purchase Price by the aggregate Restoration Cost and/or Condemnation Value related thereto, as mitigated by any repair, replacement or restoration work actually completed by the Sellers on the assets or properties being sold to the Purchaser, and proceed to Closing in which case the Sellers shall be entitled to the proceeds of any insurance or condemnation payments received in connection with such Major Loss (and, if paid to the Purchaser or the Companies, such proceeds shall be promptly remitted to the Sellers). To assist the Purchaser in its evaluation of any and all Events of Loss, the Sellers shall provide the Purchaser such access to the properties and assets and such information as the Purchaser may reasonably request in connection therewith.

(d) In the event that the aggregate Restoration Costs and/or Condemnation Value with respect to one or more Events of Loss and/or Takings equals an amount in excess of 10% of the Initial Purchase Price, then either the Purchaser or the Sellers shall have the right to terminate this Agreement.

(e) The occurrence of an Event of Loss (including a Major Loss) during the Interim Period shall not, in and of itself, be deemed a breach of the Sellers’ representations and warranties, covenants or other obligations under this Agreement absent some other breach of the Sellers’ representations and warranties, covenants or other obligations under this Agreement. The Sellers’ election pursuant to Section 6.16(b) or the decision to terminate this Agreement pursuant to Section 6.16(c) shall not, in and of itself, result in any breach of any representation, warranty or covenant of this Agreement.

Section 6.17 Consultation. From the date hereof until the Closing, the Sellers shall provide the Purchaser with regular updates as to any developments regarding any Development Project of the Transferred Companies on a reasonably prompt basis and shall cause the Transferred Companies not to enter into any material contract regarding such Development Projects without the prior written approval of the Purchaser, such approval not to be unreasonably withheld.

Section 6.18 Post-Closing Cooperation. For a period of three (3) years from and after the Closing Date, the Sellers shall reasonably cooperate (and shall cause their employees, agents and Affiliates to reasonably cooperate) with the Purchaser and its Affiliates in connection with any prospective Securities Act of 1933, as amended, filing relating to the Company and the other Transferred Companies on a consolidated basis. Such cooperation shall include making all relevant information and documents in its possession available to the Purchaser and providing assistance to the Purchaser in its compiling of the information necessary to fulfill the requirements of such filing and providing assistance to the Purchaser in its preparation of financial statements for the Company and the other Transferred Companies on a consolidated basis for the fiscal years ending December 31, 2014, December 31, 2013 and December 31, 2012, presented in accordance with SEC accounting presentation principles for public companies and as set forth by the Public Company Accounting Oversight Board. The Purchaser shall pay to the Sellers the Internal Costs and external costs and expenses reasonably incurred by the Sellers or their Affiliates in providing such cooperation and assistance. For the purpose hereof, “Internal Costs” shall mean the base salary and 100% of any projected bonus of employees providing services under the applicable covenant, on an hourly basis, plus a benefit load and overhead allocation equal to 30% of base salary.

C. except as otherwise permitted under this Section 6.19, cause WTE Holdings not to take any material action under the SPE limited liability company agreements without Purchaser’s consent and to use reasonable best efforts to cause the Minority Owners to approve all requests made by the SPE Lessees under the SPE Leases that require the consent of the Minority Owners under the SPE limited liability company agreements.

(ii) The Sellers agree not to terminate, and to use reasonable best efforts to prevent the SPEs and the lessors under the SPE Leases from terminating, the SPE Leases prior to the Facility Purchase Closing, other than as a result of material breaches of the Purchaser SPE Obligations.

(iii) The Purchaser shall:

A. cause SPE Lessees not to terminate the SPE Leases and to comply in all material respects with respect to the Purchaser SPE Obligations;

B. maintain or cause to be maintained, at its cost and expense, at a minimum, such insurance in such coverage amounts and on substantially similar terms and conditions as are required under and with respect to each SPE Lease as of the Closing, but in no event on terms less favorable than the insurance maintained by the SPE Lessees immediately prior to the Closing (the “SPE Policies”);

C. promptly forward any payments, or portion thereof, made to the Purchaser under Section 6.19(d), to the appropriate recipient pursuant to the terms of the SPE Lease Documents, to the extent any such payments would, but for this Agreement, have been made to a Person other than the Sellers, SPE Lessees or WTE Holdings.

(e) All payments made to the Purchaser by the Sellers under Section 6.19(d) shall be treated as adjustments to the Closing Purchase Price paid by the Purchaser to the Sellers under this Agreement, and the parties shall, and shall cause their Affiliates to, file all Tax Returns consistently with such position, unless otherwise required by a Governmental Authority pursuant to a determination or other proceeding. The Purchaser and the Sellers shall use reasonable best efforts to defend such position in any Tax audit or other proceeding, and shall allow the other party to fully participate (as such term is defined in Section 4.5(b) hereof) in any such defense.

(f) Unless and until the parties thereto mutually agree to a replacement guaranty or other credit support, WM Parent covenants and agrees that it shall cause the SPE Guaranty to remain in full force and effect until the earlier to occur of the Buyouts or the Facility Purchase Closings.

(g) Notwithstanding anything in this Agreement to the contrary, WTE Holdings and its Affiliates are not prohibited from continuing to pursue the buyout of the Minority Owners’ equity interests in the SPEs at or prior to the Facility Purchase Closing (the “Buyouts”). If the Buyouts are consummated prior to the Closing Date and if WTE Holdings then owns (directly or, in the case of WTE-II, through WTE-I’s ownership of WTE-II) 100% of the issued and outstanding capital stock, membership interests or other outstanding equity interests of the SPEs, the remainder of this Section 6.19 (other than Section 6.19(a)) shall be void and of no force or effect and the Sellers shall cause to be transferred, subject to regulatory approvals, if any, the capital stock of WTE Holdings (which shall then own (directly or, in the case of WTE-II, through WTE-I’s ownership of WTE-II) 100% of the issued and outstanding capital stock, membership interests or other outstanding equity interests of the SPEs) to the Company prior to

or contemporaneous with the Closing. The parties acknowledge and agree that the Purchase Price paid by the Purchaser at Closing includes the value of the SPE Facilities. Therefore, if the Buyouts are consummated after the Closing Date but prior to the Facility Purchase Closing, as soon as reasonably practicable thereafter, but in any event within 10 days after consummation of the Buyouts, the Sellers shall (i) cause to be transferred, for no additional consideration, subject to regulatory approvals, if any, the capital stock of WTE Holdings (which shall then own (directly or, in the case of WTE-II, through WTE-I’s ownership of WTE-II) 100% of the issued and outstanding capital stock, membership interests or other outstanding equity interests of the SPEs) to the Company or one of its Subsidiaries, pursuant to an assignment and transfer of the stock certificate of WTE Holdings and (ii) provide to the Purchaser a certificate executed on behalf of the Sellers by an officer of each Seller stating that the representations and warranties set forth in Section 6.19(a) are true and correct in all material respects as of such date.

Section 6.20 Spin-Off of Excluded Entities. The Sellers shall, effective prior to the Closing, cause the distribution or assignment of the equity interests of the Excluded Entities such that after such transaction, no Transferred Company owns, directly or indirectly, any equity interests of any Excluded Entity (the “Spin-Off”).

Section 6.21 Certain Joint Ventures.

(a) The Sellers shall have the right to pursue and receive the Norfolk Termination Payment or any monetary recovery, judgment, award or settlement related thereto. The Purchaser shall, and shall cause the Transferred Companies to, promptly pay to the Sellers the Norfolk Termination Payment (to the extent received by the Purchaser or the Transferred Companies) or any monetary recovery, judgment, award or settlement related thereto received by the Purchaser or any of the Transferred Companies. Purchaser shall not, and shall cause the Transferred Companies not to, take any action that would reasonably be expected to interfere with or be materially disruptive or detrimental to the Sellers’ pursuit of the Norfolk Termination Payment or any monetary recovery, judgment, award or settlement related thereto.

(b) From and after Closing, the Sellers and the Purchaser shall reasonably cooperate (and the Purchaser shall cause the Transferred Companies and their employees, agents and Affiliates to reasonably cooperate) to enter into a consulting, operation and maintenance agreement with respect to the existing transfer stations of Swire HK Joint Venture located in Hong Kong and to restructure the Swire HK Joint Venture in a manner reasonably acceptable to the Sellers and the Purchaser that, among other things, would transfer to the Transferred Companies the right to pursue waste-to-energy projects in China with Swire Pacific Ltd.

Section 6.22 Employee Non-Solicitation/Non-Hire. For a period of two (2) years following the Closing Date, none of the Sellers, the Purchaser or their respective Affiliates shall, directly or indirectly, solicit for hire or employment, or employ or engage the services of, any employee of the other party or its Affiliates involved in the procurement or sourcing of waste for the other party or its Affiliates pursuant to the Waste Supply Agreements (the “Covered Persons”); provided, however, that the foregoing shall not preclude (i) the solicitation (or

employment as a result of the solicitation) of Covered Persons whose employment with a party or its Affiliates, as applicable, has been terminated or (ii) the solicitation (or employment as a result of the solicitation) of Covered Persons through public advertisements or general solicitations that are not specifically targeted at such Covered Persons.

Section 6.23 Tax-Exempt Financed Assets.

(a) WM Parent is and, upon Closing, will remain financially obligated on the Tax-Exempt WM Parent Debt that financed certain facilities of the Company (the “Applicable Facilities”). The Purchaser acknowledges that (i) prior to Closing, neither the Sellers nor WM Parent intend to defease or redeem the Tax-Exempt WM Parent Debt and (ii) upon Closing, use and ownership of the Applicable Facilities will reside with the Purchaser. The Sellers hereby represent, and the Purchaser acknowledges that, upon Closing: (xi) interest paid or accrued on the Tax-Exempt WM Parent Debt is excludable from the gross income of the holders thereof for purposes of federal income taxation; (xii) pursuant to the Code, the basis of such federal income tax exclusion for interest payable to such holders is the use of the Applicable Facilities for certain qualified purposes, including “solid waste disposal facilities” (as such term is used in Section 142(a)(6) of the Code) as and to the extent the Applicable Facilities are so-currently used by the Company (or its applicable Subsidiary); (xiii) the use of all or part of the Applicable Facilities for a purpose other than a qualifying purpose or purposes may cause (A) the interest payable on all or part of the Tax-Exempt WM Parent Debt to not be excludable from the federal gross income of the holders thereof possibly with retroactive effect, and/or (B) the deductibility of the interest payable by WM Parent on all or part of the Tax-Exempt WM Parent Debt to be disallowed by Section 150(b) of the Code; and (xiv) the Purchaser, the Company and the Transferred Companies shall not have any obligation with respect to the Tax-Exempt WM Parent Debt, except for the obligations set forth in Section 6.23(b).

(b) On and after Closing and until December 1, 2017, Purchaser agrees to provide at least ninety (90) days’ prior written notice to each of WM Parent and the Sellers of a change in the use of the Applicable Facilities for a purpose other than so-currently used (as currently operating in the Ordinary Course of Business).

(c) For avoidance of doubt, in no event shall the Purchaser, the Company or the Transferred Companies be liable for any of the tax liabilities or obligations of WM Parent or its affiliates under the Tax-Exempt WM Parent Debt.

Section 6.24 Certain Broward Matters. The parties shall take the actions described on Schedule 6.24.

If this Agreement is terminated by either the Purchaser or the Sellers pursuant to the provisions of Section 8.1, in no event shall the liability of any party for damages incurred by the other party or its Affiliates for any breach of this Agreement (whether under this Agreement or arising under Law) or any certificate or document delivered pursuant hereto exceed the General Cap. For purposes of this Agreement, the term “Willful Breach” means a material breach of any material representation, warranty or covenant or other agreement set forth in this Agreement that is a consequence of an intentional act or failure to act by the other party with the actual knowledge that the taking of such act or failure to take such act would cause a breach of this Agreement.

Section 8.3 Termination Fees.

(a) In the event that

(i) this Agreement is terminated by the Sellers in accordance with the terms hereof as contemplated pursuant to (x) Section 8.1(a)(iv) or (y) Sections 8.1(a)(i) and (iii), then within two (2) Business Days of such termination, the Purchaser shall pay to the Sellers the Purchaser Termination Fee as liquidated damages and not as a penalty by wire transfer to an account specified in writing by the Sellers; or

(ii) (A) all of the conditions set forth in Section 7.1 and Section 7.2 have been satisfied or waived by the party or parties entitled to waive such conditions (other than (x) those conditions in Sections 7.1(e) and 7.2(f) and (y) those conditions that by their nature are to be satisfied at the Closing, each of which conditions in this clause (y) shall be capable of being satisfied if the Closing Date were the date that notice of termination is delivered), (B) the Purchaser shall have failed to consummate the Closing on or before the Termination Date, and (C) this Agreement is terminated in accordance with the terms hereof by either the Sellers pursuant to Section 8.1(a)(ii) or the Purchaser pursuant to Section 8.1(b)(ii), in each case due to the failure to satisfy the conditions in Sections 7.1(e) and 7.2(f), then within two (2) Business Days of such termination, the Purchaser shall pay to the Sellers an amount equal to the Special Purchaser Termination Fee as liquidated damages and not as a penalty by wire transfer to an account specified in writing by the Sellers;

it being understood that in no event shall the Purchaser be required to pay a Termination Fee on more than one occasion.

(b) Each of the parties hereto acknowledges that the agreements contained in this Section 8.3 are an integral part of the transactions contemplated by this Agreement, and that without these agreements, the other parties would not enter into this Agreement; accordingly, if the Purchaser fails to timely pay any amount due pursuant to this Section 8.3, and, in order to obtain the payment, the Sellers commence an action which results in a judgment against the Purchaser for the payment of a Termination Fee, the Purchaser shall also be liable to the Sellers for their reasonable out-of-pocket costs and expenses (including reasonable attorneys’ fees) in connection with such suit, together with interest on such Termination Fee at the rate of eight percent (8.0%) through the date such payment was actually received.

(c) Notwithstanding anything to the contrary in this Agreement, if the Purchaser pays a Termination Fee pursuant to this Section 8.3, except for claims by the Sellers that the Purchaser Termination Fee should be paid instead of the Special Purchaser Termination Fee, the Sellers agree that their receipt of such Termination Fee as set forth in Section 8.3(a) shall be the sole and exclusive remedy of the Sellers and their Affiliates (whether at law, in equity, in contract, in tort or otherwise) against the Purchaser, the ECP Guarantor, the Lenders and any of their respective former, current or future directors, officers, employees, agents, general or limited partners, managers, members, stockholders, Affiliates or assignees or any former, current or future director, officer, employee, agent, general or limited partner, manager, member, stockholder, Affiliate or assignee of any of the foregoing (collectively, the “Purchaser Related Parties”) for any loss or damage suffered as a result of any breach of any representation, warranty, covenant or agreement in this Agreement or the failure of the transactions contemplated by this Agreement to be consummated; and upon payment of such fee, the Purchaser Related Parties shall have no further liability or obligation relating to or arising

out of this Agreement, any certificate, instrument or agreement delivered in connection with this Agreement (including the Commitment Letters and the Limited Guarantee) or the transactions contemplated by this Agreement (except, for the avoidance of doubt, for the ECP Guarantor’s obligations under the Limited Guarantee, subject to the limitations contained therein) or thereby or any other document or written or oral representation made or alleged to be made in connection herewith or therewith, through the Purchaser or otherwise, whether by or through attempted piercing of the corporate (or limited liability company or limited partnership) veil, by or through a claim (whether at law, in equity, in contract, in tort or otherwise) by or on behalf of the Purchaser against the ECP Guarantor or any other Purchaser Related Party, by the enforcement of any assessment or by any legal or equitable proceeding, by virtue of any statute, regulation or other applicable Law, or otherwise.

Section 8.4 Amendment. This Agreement may not be amended except by an instrument in writing signed on behalf of all of the parties hereto. Notwithstanding anything to the contrary herein, Section 8.3(c), Section 8.4, Section 9.7, Section 10.5 and Section 10.6 (and any provision of this Agreement to the extent an amendment, modification or supplementation of such provision would modify the substance of such Sections) may not be amended, modified or supplemented in a manner that adversely affects the rights of the Lenders without the prior written consent of the Lenders.

Section 8.5 Extensions; Waiver. At any time prior to the Closing Date, the parties hereto may (a) extend the time for the performance of any of the obligations or other acts of the other parties hereto, (b) waive any inaccuracies in the representations and warranties contained herein or in any document delivered pursuant thereto and (c) waive compliance with any of the agreements or conditions herein. Any agreement on the part of a party hereto to any such extension or waiver shall be valid only if set forth in an instrument in writing signed by all of the parties to this Agreement.

(a) any breach or misrepresentation in any of the representations and warranties made by or on behalf of the Sellers in this Agreement or any closing certificate delivered to the Purchaser in connection with the Closing, including any breach or misrepresentation of any representation or warranty set forth in Section 3.8 (to the extent not otherwise described in Section 9.1(c));

(e) (x) any amounts payable by the Sellers to the Purchaser pursuant to Section 6.19(d)(i)A and B, (y) the failure of the payments made by the Sellers under Section 6.19(d)(i)A and B to be treated as described in Section 6.19(e) and (z) any breach or misrepresentation in any of the representations and warranties made by or on behalf of the Sellers either (1) on the date hereof pursuant to Section 6.19(a) or (2) in the certificate delivered pursuant to Section 6.19(g); and

(f) the Excluded Entities or the Spin-Off pursuant to Section 6.20 hereof, including any costs, expenses or Taxes incurred in connection with the Spin-Off.

For purposes of this Section 9.1 (including for purposes of determining whether a breach of any representations and warranties of the Sellers has occurred), all representations and warranties of the Sellers in this Agreement shall be construed as if the terms “material” and “in all material respects” (and variations thereof) and any reference to “Material Adverse Effect” (and all variations thereof) used therein were omitted from such representations and warranties (including the use of such terms in definitions of the defined terms used therein), other than in (i) references to “Material Agreements,” and (ii) references to “material” in Section 3.13 (Contracts, Agreements, Plans and Commitments).

Section 9.2 Purchaser Indemnity Obligations. The Purchaser, and if the Closing occurs, the Company, on a joint and several basis with the Purchaser, shall indemnify and hold harmless the Sellers and the Sellers’ Affiliates and each of their respective officers, directors, stockholders, members, managers, employees, agents and representatives (each a “Seller Indemnified Party”) from and against, and shall reimburse the Seller Indemnified Parties for, any and all Indemnified Amounts paid, imposed on or incurred by a Seller Indemnified Party or for which a Seller Indemnified Party bears responsibility directly or indirectly, resulting from, caused by, arising out of, or in any way relating to and with respect to any of, or any allegation by any third party of, the following:

(a) any breach or misrepresentation in any of the representations and warranties made by or on behalf of the Purchaser in this Agreement or any closing certificate delivered by the Purchaser to the Sellers in connection with the Closing;

(b) any violation or breach by (i) the Purchaser of or default by the Purchaser under any covenant, agreement or undertaking contained in this Agreement or any closing certificate delivered to the Sellers in connection with the Closing (ii) the Company of or default by the Company under any post-closing covenant, agreement or undertaking contained in this Agreement;

(e) any violations of Section 409A of the Code that result from the Purchaser’s failure to comply with the notice requirement of Section 6.11(f).

For purposes of this Section 9.2 (including for purposes of determining whether a breach of any representations and warranties of the Purchaser has occurred), all representations and warranties of the Purchaser in this Agreement shall be construed as if the terms “material” and “in all material respects” (and variations thereof) and any reference to “Material Adverse Effect” (and all variations thereof) used therein were omitted from such representations and warranties (including the use of such terms in definitions of the defined terms used therein).

Section 9.3 Indemnification Procedures. All claims for indemnification under this Agreement shall be asserted and resolved as follows:

(a) Subject to the additional obligations set forth in Section 9.3(b) below and the limitations set forth in Section 10.1, a party claiming indemnification under this Agreement (an “Indemnified Party”) shall promptly (i) notify the party from whom indemnification is sought (the “Indemnifying Party”) of any third-party claim or claims asserted against the Indemnified Party (“Third Party Claim”) for which indemnification is sought and (ii) transmit to the Indemnifying Party a copy of all papers served with respect to such claim (if any) and a written notice (“Claim Notice”) containing a description in reasonable detail of the nature of the Third Party Claim, an estimate of the amount of damages attributable to the Third Party Claim to the extent feasible (which estimate shall not be conclusive of the final amount of such claim) and the basis of the Indemnified Party’s request for indemnification under this Agreement. The failure by an Indemnified Party to promptly notify an Indemnifying Party of an indemnity claim shall not relieve an Indemnifying Party of its indemnity obligations under this Agreement except to the extent the Indemnifying Party is prejudiced by such delay.

Within fifteen (15) days after receipt of any Claim Notice (the “Election Period”), the Indemnifying Party shall notify the Indemnified Party (i) whether the Indemnifying Party disputes its potential liability to the Indemnified Party with respect to such Third Party Claim and (ii) whether the Indemnifying Party desires, at the sole cost and expense of the Indemnifying Party, to defend the Indemnified Party against such Third Party Claim.

If the Indemnifying Party notifies the Indemnified Party within the Election Period that the Indemnifying Party elects to assume the defense of the Third Party Claim, then the Indemnifying Party shall have the right to defend, at its sole cost and expense and with counsel reasonably acceptable to the Indemnified Party, such Third Party Claim by all appropriate proceedings, which proceedings shall be prosecuted diligently by the Indemnifying Party to a final conclusion or settled at the reasonable discretion of the Indemnifying Party in accordance with this Section 9.3. The Indemnifying Party shall have full control of such defense and proceedings. The Indemnified Party is hereby authorized, at the sole cost and expense of the Indemnifying Party, to file, during the Election Period, any motion, answer or other pleadings that the Indemnified Party shall reasonably deem necessary or appropriate to protect its interests. If requested by the Indemnifying Party, the Indemnified Party agrees to reasonably cooperate with the Indemnifying Party and its counsel in contesting any Third Party Claim that the Indemnifying Party elects to contest, including without limitation the making of any related counterclaim against the person asserting the Third Party Claim or any cross-complaint against any Person. Except as otherwise provided herein, the Indemnified Party may participate in, but not control, any defense or settlement of any Third Party claim controlled by the Indemnifying Party pursuant to this Section 9.3 and shall bear its own costs and expenses with respect to such participation.

If the Indemnifying Party fails to notify the Indemnified Party within the Election Period that the Indemnifying Party elects to defend the Indemnified Party pursuant to the preceding paragraph, or if the Indemnifying Party elects to defend the Indemnified Party but fails to prosecute or settle the Third Party Claim as herein provided, or if the Indemnified Party reasonably objects to such election on the grounds that counsel for such Indemnifying Party cannot represent both the Indemnified Party and the Indemnifying Parties because such representation would be reasonably likely to result in a conflict of interest, then the Indemnified Party shall have the right to defend, at the sole cost and expense of the Indemnifying Party, the Third Party Claim by all appropriate proceedings, which proceedings shall be prosecuted by the Indemnified Party to a final conclusion or settled. If requested by the Indemnified Party, the Indemnifying Party agrees to reasonably cooperate with the Indemnified Party and its counsel in contesting any Third Party Claim. The Indemnified Party shall have full control of such defense and proceedings. The Indemnifying Party may participate in, but not control, any defense or settlement controlled by the Indemnified Party pursuant to this Section 9.3, and the Indemnifying Party shall bear its own costs and expenses with respect to such participation.

The Indemnifying Party shall not settle or compromise any Third Party Claim unless (i) the terms of such compromise or settlement require no more than the payment of money (i.e., such compromise or settlement does not require the Indemnified Party to

admit any wrongdoing or take or refrain from taking any action), (ii) the full amount of such monetary compromise or settlement will be paid by the Indemnifying Party and (iii) the Indemnified Party receives as part of such settlement a legal, binding and enforceable unconditional satisfaction and/or release, in form and substance reasonably satisfactory to it, providing that such Third Party Claim and any claimed liability of the Indemnified Party with respect thereto is being fully satisfied by reason of such compromise or settlement and that the Indemnified Party is being released from any and all obligations or liabilities it may have with respect thereto. The Indemnified Party shall not settle or admit liability to any Third Party Claim without the prior written consent of the Indemnifying Party unless (x) the Indemnifying Party has disputed its potential liability to the Indemnified Party, and such dispute either has not been resolved or has been resolved in favor of the Indemnifying Party or (y) the Indemnifying Party has failed to respond to the Indemnified Party’s Claim Notice. Notwithstanding anything in the foregoing and for the purpose of clarity, the Sellers shall the full right to control and direct any litigation regarding the Excluded Entities.

(b) In the event any Indemnified Party should have a claim against any Indemnifying Party hereunder that does not involve a Third Party Claim, the Indemnified Party shall transmit to the Indemnifying Party a written notice describing in reasonable detail the nature of the claim, an estimate of the amount of damages attributable to such claim to the extent feasible (which estimate shall not be conclusive of the final amount of such claim) and the basis of the Indemnified Party’s request for indemnification under this Agreement.

Section 9.4 Determination of Indemnified Amounts. The Indemnified Amounts payable by an Indemnifying Party hereunder shall be determined (i) by the written agreement of the parties, (ii) by a judgment or decree of any court of competent jurisdiction, or (iii) by any other means agreed to in writing by the parties. The amount of any Indemnified Amounts for which indemnification is provided under this Article IX shall be net (x) of any amounts actually recovered by the Indemnified Party from third parties under insurance policies with respect to such Indemnified Amounts and (y) net of any Tax Benefit derived by an Indemnified Party (or any Affiliate thereof) with respect to such Damages or any of the circumstances giving rise thereto. All parties shall use commercially reasonably efforts to mitigate the amount of Indemnified Amounts for which they may be entitled to indemnification hereunder, including, without limitation, in the case of the Purchaser, by using reasonable best efforts to recover against the Transferred Companies’ insurance policies. If an indemnification payment is received by a Purchaser Indemnified Party, and any Purchaser Indemnified Party or Transferred Company later receives insurance proceeds from third parties in respect of the related Indemnified Amounts, the Purchaser shall immediately pay to the Sellers a sum equal to the lesser of (a) the amount of such insurance proceeds received (net of any costs and expenses and/or increased premiums paid or incurred by the Purchaser or the Transferred Companies to recover such proceeds) or (b) the actual amount of the indemnification payment previously paid by the Sellers with respect to such Indemnified Amounts.

Section 9.5 Limitation of the Sellers’ Liability.

(a) Notwithstanding anything to the contrary contained in this Article IX, the aggregate liability of the Sellers for any event or occurrence giving rise to the Sellers being required to indemnify the Purchaser Indemnified Parties pursuant to Section 9.1(a) and Section 9.1(b) of this Agreement shall be limited to $125,000,000 (the “General Cap”); provided, however, that the General Cap shall not apply to any claims relating to a breach of any Fundamental Representation.

(b) The Purchaser Indemnified Parties shall not be entitled to be indemnified pursuant to Section 9.1(a) and Section 9.1(b) unless and until: (i) the amount of any Indemnified Amount (or a series of related or similar Indemnified Amounts) exceeds $250,000 (a “Non-De Minimis Claim”) and (ii) the aggregate amount of all Non-De Minimis Claims exceeds one percent (1.0%) of the Initial Purchase Price (the “Deductible Amount”); provided, however, that the foregoing limitations shall not apply to (x) any claims relating to a breach of any Fundamental Representation or (y) in the case of Section 9.1(b), any Willful Breach of a covenant, agreement or undertaking (other than Section 6.1), and any amounts recovered with respect to such matters shall not count in determining whether any of the limitations in this Section 9.5(b) have been met or exceeded. After the Deductible Amount is exceeded, the Purchaser Indemnified Parties shall be entitled to seek indemnification pursuant to Section 9.1(a) and Section 9.1(b) for the entire amount (including the first $250,000) of all Non-De Minimis claims in excess of (but not including) the Deductible Amount, subject to the General Cap as set forth in Section 9.5(a).

(c) Without limiting the limitations on indemnity set forth in Sections 9.5(a) and (b) above, in no event shall the Sellers’ aggregate indemnification obligations under this Agreement exceed 100% of the Initial Purchase Price.

Section 9.6 Limitation of the Purchaser’s Liability. Notwithstanding anything to the contrary contained in this Article IX, the aggregate liability of the Purchaser for any event or occurrence giving rise to the Purchaser being required to indemnify the Seller Indemnified Parties shall be limited to the Initial Purchase Price, except for indemnification obligations under Section 9.2(b), Section 9.2(c), Section 9.2(d) and Section 9.2(e).

Section 9.7 Exclusive Remedy.

(a) Except for claims for Fraud, specific performance and injunctive relief, the payment of a Termination Fee pursuant to Section 8.3 and the indemnification provided in this Article IX shall be the sole and exclusive remedies for any breach of this Agreement (whether under this Agreement or arising under Law) or any certificate or document delivered pursuant hereto. Any liability for indemnification hereunder shall be determined without duplication of recovery for liabilities by reason of the same state of facts giving rise to such liability constituting a breach of more than one representation, warranty, covenant or agreement or by reason of a party to this Agreement receiving an adjustment to the Purchase Price pursuant to Article I in connection with the facts giving rise to the right of indemnification. In no event shall the Sellers’ have any liability to the

Purchaser with respect to any losses based upon, arising out of or otherwise in respect of, any fact, matter, event or circumstance which was specifically disclosed in any Phase I investigation (or update thereof) of the Real Property conducted by or on the behalf of the Purchaser prior to the date hereof. Except for the foregoing, an Indemnifying Party’s liability for any breach of the representations and warranties set forth herein shall not be impacted or limited by any knowledge that the Indemnified Party had of any event, action or circumstance giving rise to such breach prior to the Closing.

(b) The parties to this Agreement have voluntarily agreed to define their rights, liabilities and obligations respecting the subject matter of this Agreement exclusively in contract pursuant to the express terms and provisions of this Agreement; and the parties to this Agreement expressly disclaim that they are owed any duties or are entitled to any remedies not expressly set forth in this Agreement except in the case of Fraud. The parties to this Agreement acknowledge and agree that all representations and warranties set forth in this Agreement and closing certificates related thereto are contractual in nature only and subject to the sole and exclusive remedies set forth herein, except in the case of Fraud. The parties to this Agreement have agreed that should any representations and warranties of any party to this Agreement prove untrue, the other party to this Agreement shall have the specific rights and remedies herein specified as the exclusive remedy therefor, but that, except in the case of Fraud, no other rights, remedies or causes of action (whether in law or in equity or whether in contract or in tort) are permitted to any party to this Agreement hereto as a result of the untruth of any such representation and warranty. Furthermore, the parties to this Agreement each hereby acknowledge that this Agreement embodies the justifiable expectations of sophisticated parties derived from arm’s length negotiations; all parties to this Agreement specifically acknowledge that neither party to this Agreement has any special relationship with the other party to this Agreement that would justify any expectation beyond that of an ordinary buyer and an ordinary seller in an arm’s length transaction. Except for Fraud or as otherwise explicitly set forth herein, including provisions providing for specific performance in Section 10.9, the sole and exclusive remedies for any breach or failure to perform this Agreement shall be those remedies set forth herein (including Article VIII and this Article IX); and the parties to this Agreement hereby waive and release any and all tort claims and causes of action that may be based upon, arise out of or relate to this Agreement, or the negotiation, execution or performance of this Agreement (including any tort claim or cause of action based upon, arising out of or related to any representation or warranty made in or in connection with this Agreement or as an inducement to enter this Agreement).

Section 10.3 Interpretation. The headings contained in this Agreement are for reference purposes only and shall not affect in any way the interpretation of this Agreement. In this Agreement, unless a contrary intention appears, (i) the words “herein,” “hereof” and “hereunder” and other words of similar import refer to this Agreement as a whole and not to any particular Article, Section or other subdivision, (ii) the words “including,” “including without limitation,” and “including but not limited to” and other words of similar import do not imply any limitation on (but may expand) the antecedent reference, (iii) reference to any Article or Section means such Article or Section hereof, (iv) the singular shall include the plural, the plural shall include the singular, and the masculine gender shall include the feminine and neutral genders and vice versa. (v) the word “or” will have the inclusive meaning represented by the phrase “and/or;” and “shall” and “will” mean “must,” and shall have equal force and effect and express an obligation, (vi) the term “day” shall mean a calendar day, commencing at 12:00 a.m. (local time) and the term “month” shall mean a calendar month; provided that when a period measured in months commences on a date other than the first day of a month, the period shall run from the date on which it starts to the corresponding date in the next month and, as appropriate, to succeeding months thereafter, (vii) all references to a particular entity shall include such entity’s permitted successors and permitted assigns unless otherwise specifically provided herein, (viii) all references herein to any Law or to any contract shall be to such Law as of the date hereof or contract as amended, supplemented or modified (in accordance with the terms hereof) from time to time unless otherwise specifically provided herein and (ix) all monetary amounts contained in this Agreement refer to currency of the United States. Whenever an event is to be performed or a payment is to be made by a particular date and the date in question falls on a day which is not a Business Day, the event shall be performed, or the payment

shall be made, on the next succeeding Business Day; provided, however, that all calculations shall be made regardless of whether any given day is a Business Day and whether or not any given period ends on a Business Day. Time is of the essence in this Agreement. No provision of this Agreement shall be interpreted or construed against any party hereto solely because such party or its legal representative drafted such provision. The parties intend that each representation, warranty, and covenant contained herein shall 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) which the party has not breached shall not detract from or mitigate the fact that the party is in breach of the first representation, warranty or covenant.

Section 10.4 Miscellaneous. This Agreement (including the documents, instruments and agreements delivered in connection herewith) (i) constitute the entire agreement and supersedes all other prior agreements and understandings, both written and oral, among the parties and their Affiliates, or any of them, with respect to the subject matter hereof, including, without limitation, that certain No-Shop Agreement dated November 20, 2013, as amended, between Waste Management, Inc. and Energy Capital Partners II, LLC; that certain Indicative Proposal Letter dated November 6, 2013 from Energy Capital Partners to Waste Management, Inc.; and that certain Proposal Confirmation Letter dated January 15, 2014 from Energy Capital Partners to Waste Management, Inc. (all of which are hereby terminated by this reference), and (ii) shall not be assigned by operation of law or otherwise. Notwithstanding the foregoing, the Purchaser may assign (x) this Agreement (in whole but not in part) to one or more Affiliates or (y) their rights under this Agreement on or after the Closing, to any Lender or any other party providing debt financing to the Purchaser (or any agent or collateral trustee for any such Person) as collateral in connection with any such debt financing; provided that in each case the Purchaser remains liable hereunder.

Section 10.5 Governing Law; Venue.

(a) THIS AGREEMENT SHALL BE GOVERNED IN ALL RESPECTS, INCLUDING VALIDITY, INTERPRETATION AND EFFECT, BY THE LAWS OF THE STATE OF NEW YORK APPLICABLE TO CONTRACTS EXECUTED AND TO BE PERFORMED WHOLLY WITHIN SUCH STATE. Each of the parties hereto agrees that any action or proceeding brought to enforce the rights or obligations of any party hereto under this Agreement shall be commenced and maintained in the Supreme Court of the State of New York, County of New York (or, if under applicable law exclusive jurisdiction is vested in the Federal courts, the United States District Court for the Southern District of New York sitting in New York County), as well as all courts from which an appeal may be taken from such courts (each, a “Court”). Each party hereto (i) expressly and irrevocably consents and submits to the exclusive jurisdiction of each Court in connection with any action or proceeding arising out of or in connection with this Agreement or the transactions contemplated hereby or the enforcement of any rights under this Agreement; (ii) agrees that each Court shall be deemed to be a convenient forum; and (iii) agrees not to assert, by way of motion, as a defense or otherwise, in any such proceeding commenced in any Court, any claim that such party is not subject personally to the jurisdiction of such Court, that such proceeding has been

brought in an inconvenient forum, that the venue of such proceeding is improper or that this Agreement or the subject matter of this Agreement may not be enforced in or by such Court. Each of the Purchaser and ECP Guarantor hereby appoints the person identified under such party’s name in Section 10.2 as such party’s agent for service of process, and agrees that service of process in any such proceeding may be made by certified mail, return receipt requested, addressed to such agent. Each Seller irrevocably appoints the person identified under such parties’ name in Section 10.2 as its agent for the sole purpose of receiving service of process or other legal summons in connection with any Action. Without limiting the foregoing, each party agrees that service of process on such party as provided in this Section 10.5 shall be deemed effective service of process on such party.

(b) Each of the parties agrees that it will not bring or support any suit, action or legal proceeding of any kind or description, whether in law or in equity, whether in contract or in tort or otherwise, against the Lenders and their respective Affiliates and representatives in any way relating to this Agreement or any of the transactions contemplated by this Agreement, including but not limited to any dispute arising out of or relating in any way to the Debt Commitment Letter or the performance thereof, in any forum other than the Supreme Court of the State of New York, County of New York, or, if under applicable law exclusive jurisdiction is vested in the Federal courts, the United States District Court for the Southern District of New York sitting in New York County (and appellate courts thereof), and makes the agreements, waivers and consents set forth in Section 10.5(a) with respect thereto.

Section 10.6 Waiver of Jury Trial. THE PARTIES HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVE ANY RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM ARISING OUT OF OR RELATING TO THIS AGREEMENT, THE COMMITMENT LETTERS OR ANY TRANSACTION CONTEMPLATED HEREBY OR THEREBY (INCLUDING THE FINANCING) OR THE ACTIONS OF THE PARTIES IN THE NEGOTIATION, EXECUTION, PERFORMANCE AND ENFORCEMENT OF THIS AGREEMENT, WHETHER NOW EXISTING OR HEREAFTER ARISING, AND WHETHER SOUNDING IN CONTRACT, TORT OR OTHERWISE. THE PARTIES AGREE THAT ANY OF THEM MAY FILE A COPY OF THIS PARAGRAPH WITH ANY COURT AS WRITTEN EVIDENCE OF THE KNOWING, VOLUNTARY AND BARGAINED FOR AGREEMENT AMONG THE PARTIES IRREVOCABLY TO WAIVE TRIAL BY JURY AND THAT ANY ACTION OR PROCEEDING WHATSOEVER BETWEEN THEM RELATING TO THIS AGREEMENT, THE COMMITMENT LETTERS OR ANY TRANSACTION CONTEMPLATED HEREBY OR THEREBY SHALL INSTEAD BE TRIED IN A COURT OF COMPETENT JURISDICTION BY A JUDGE SITTING WITHOUT A JURY.

Section 10.7 Counterparts. This Agreement may be executed in two or more counterparts, each of which shall be deemed to be an original, but all of which shall constitute one and the same agreement.

Section 10.8 Parties in Interest. This Agreement shall be binding upon and inure solely to the benefit of each party hereto, and, other than Section 6.7, nothing in this Agreement, express or implied, is intended to confer upon any other Person any rights or remedies of any nature whatsoever under or by reason of this Agreement; provided, however, that (x) Section 8.3(c) shall be for the benefit of, and enforceable by, the Purchaser Related Parties, (y) Section 10.14 shall be for the benefit of, and enforceable by, the Nonparty Affiliates of the parties and (z) Section 8.3(c), 8.4, 9.7, 10.3, 10.5(b), 10.6, 10.8 and 10.14 shall be for the benefit of, and enforceable by, the Lenders and their respective Affiliates and representatives.

Section 10.9 Remedies; Specific Performance.

(a) The parties agree that irreparable damage for which monetary damages, even if available, would not be an adequate remedy, would occur in the event that the parties hereto do not perform the provisions of this Agreement in accordance with its specified terms or otherwise breach such provisions. The parties acknowledge and agree that, prior to the valid termination of this Agreement pursuant to Article VIII, the non-breaching party shall be entitled, in addition to any other remedy to which it is entitled as contemplated in Section 9.7, to an injunction, specific performance and other equitable relief to prevent breaches of this Agreement by any other party and to enforce specifically the terms and provisions hereof except that any such claims against the Purchaser shall be limited as provided in Section 10.9(b). Each of the parties hereto (i) agrees that it shall not oppose the granting of any such relief; (ii) hereby irrevocably waives any requirement for the securing or posting of any bond in connection with any such relief (it is understood that clause (i) of this sentence is not intended to, and shall not, preclude any party hereto from litigating on the merits the substantive claim to which such remedy relates); and (iii) agrees that the prevailing party shall be entitled to reimbursement of all reasonable costs and expenses including without limitation, all reasonable attorneys’ fees.

(b) Notwithstanding Section 10.9(a), it is acknowledged and agreed that the Sellers shall be entitled to seek specific performance (x) to enforce Purchaser’s obligation to send a drawdown notice under the Debt Commitment Letter, and (y) solely in its capacity as third party beneficiary of the Equity Commitment Letter to seek specific performance of the Purchaser’s obligation to cause the Equity Financing to be funded to fund the transactions contemplated by this Agreement and to cause the Purchaser to consummate the transactions contemplated in this Agreement, in each case, only in the event that each of the following conditions has been satisfied: (i) all of the conditions in Section 7.2 shall have been satisfied or waived by the Purchaser (other than those conditions that by their nature are to be satisfied at the Closing, each of which conditions shall be capable of being satisfied if the Closing Date were the date such specific performance is sought or the failure of which to be satisfied, is caused by breach by Purchaser of its representations, warranties, covenants or agreements contained in this Agreement) and shall remain satisfied as of the time when Closing is required to have occurred pursuant to Section 1.4, (ii) in the case of clause (y), the Debt Financing has been funded or will be funded at the Closing if the Equity Financing is funded, (iii) the Purchaser fails to complete the Closing in accordance with Section 1.4, and (iv) the Sellers have confirmed by irrevocable written notice to the Purchaser that if specific performance is granted and the Debt Financing and Equity Financing is funded, then the Closing will occur, and that the Sellers are willing to waive any unsatisfied conditions in Section 7.1 (but solely for purposes of consummating the transactions contemplated by

this Agreement). For the avoidance of doubt, while the Sellers may pursue both a grant of specific performance of the Purchaser’s obligations as, and only to the extent, expressly permitted by this Section 10.9(b), and the payment of a Termination Fee as provided by Section 8.3, under no circumstances shall the Sellers be permitted or entitled to receive both such grant of specific performance (and the subsequent successful effecting of the Closing) and payment of a Termination Fee.

Section 10.10 Validity. The invalidity or unenforceability of any provision of this Agreement shall not affect the validity or enforceability of any other provisions of this Agreement, which shall remain in full force and effect.

Section 10.11 Time is of the Essence. Time is of the essence with respect to the time periods set forth or referred to in this Agreement.

Section 10.12 Confidentiality. Subject to Section 5.3, each of the parties hereto agrees that neither it, its Affiliates nor its nor its Affiliates’ officers, directors, employees, agents, advisors, counsel or representatives shall reveal to any other Person other than its auditors and lenders (a) the terms of this Agreement or any of the terms of the documents executed or to be executed pursuant hereto and (b) any financial, commercial, technical or other confidential information relating to the Purchaser, the Sellers, the Transferred Companies or the Business; provided, however, the Purchaser’s obligations under this clause (b) shall terminate at the Closing except with respect to confidential information related to the Sellers or the WM Companies for a period of three (3) years after the Closing Date. The obligations set forth in the immediately preceding sentence shall not apply to the disclosure of any information (i) as may be hereafter mutually agreed to in writing, (ii) as ordered by a judicial tribunal, (iii) with respect to clause (a) above, to any of such parties’ directors, officers, employees or attorneys and directors, officers and employees of affiliated companies and representatives thereof or their advisors who need to know such information for the purpose of consummating the transactions contemplated by this Agreement and the documents executed or to be executed pursuant hereto, (iv) with respect to clause (b) above, to any of such parties’ directors, officers, employees or attorneys who need to know such information for the purpose of consummating the transactions contemplated by this Agreement and the documents executed or to be executed pursuant hereto, (v) to the extent required to be disclosed by applicable Legal Requirements or legal process; provided that the disclosing party notifies the non-disclosing party promptly (unless prohibited by Law) and provides the non-disclosing party with a reasonable opportunity to seek an appropriate protective order or other appropriate remedy (unless prohibited by Law) for non-disclosure of such confidential information, (vi) that is available in the public domain through no breach by a party hereto of its obligations hereunder or (vii) in connection with (A) any action or proceeding by a party to enforce its rights under this Agreement or any of the documents to be executed pursuant hereto or (B) the defense of any action or proceeding against a party, any of its Affiliates or any representatives of any of the foregoing. Notwithstanding the foregoing, the Purchaser and its Affiliates may, without the prior consent of the Sellers, issue any non-public release or statement or otherwise disclose information with respect to this Agreement, other transaction documents or the transactions (including the Purchase Price and other terms of the Agreement or other transaction documents) to any of its or their respective Affiliates, Purchaser Representatives, Lenders and current and potential investors, in each case, which are subject to contractual confidentiality obligations with respect to the information disclosed to them (whether pursuant to such release or statement or otherwise). Each of the parties hereto will use at least the same standard of care in protecting such confidential information as it uses in protecting its own confidential information.

Section 10.13 Severability. If any condition, term or other provision of this Agreement is invalid, illegal, or incapable of being enforced by any Law or public policy, all other conditions, terms or provisions of this Agreement shall nevertheless remain in full force and effect so long as the economic or legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to any party. Upon such determination that any term or other provision is invalid, illegal, or incapable of being enforced, 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 an acceptable manner in order that the transactions contemplated hereby are consummated as originally contemplated to the greatest extent possible. Notwithstanding the foregoing, the parties intend that the provisions of Article VIII and Article IX, including the remedies (and limitations thereon) and the limitations on representations, warranties and covenants, be construed as integral provisions of this Agreement and that such provisions, remedies and limitations shall not be severable in any manner that diminishes a party’s rights hereunder or increases a party’s liability or obligations hereunder.

Section 10.14 Non-Recourse. Except to the extent otherwise set forth in the Limited Guarantee, the WM Guarantee and the Equity Commitment Letter, all claims, obligations, liabilities, or causes of action (whether in contract or in tort, in law or in equity, or granted by statute) that may be based upon, in respect of, arise under, out or by reason of, be connected with, or relate in any manner to this Agreement, or the negotiation, execution, or performance of this Agreement (including any representation or warranty made in, in connection with, or as an inducement to, this Agreement), may be made only against (and such representations and warranties are those solely of) the Persons that are expressly identified as parties in the preamble to this Agreement (the “Contracting Parties”). No Person who is not a Contracting Party, including any current, former or future director, officer, employee, incorporator, member, partner, manager, stockholder, Affiliate, agent, attorney, representative or assignee of, and any financial advisor or lender (including the Lenders) to, any Contracting Party, or any current, former or future director, officer, employee, incorporator, member, partner, manager, stockholder, Affiliate, agent, attorney, representative or assignee of, and any financial advisor or lender to, any of the foregoing (collectively, the “Nonparty Affiliates”), shall have any liability (whether in contract or in tort, in law or in equity, or granted by statute) for any claims, causes of action, obligations, or liabilities arising under, out of, in connection with, or related in any manner to this Agreement or based on, in respect of, or by reason of this Agreement or its negotiation, execution, performance, or breach (other than as set forth in the Limited Guarantee, the WM Guarantee and the Equity Commitment Letter), and, to the maximum extent permitted by Law, each Contracting Party hereby waives and releases all such liabilities, claims, causes of action, and obligations against any such Nonparty Affiliates. Without limiting the foregoing, to the maximum extent permitted by Law, except to the extent otherwise set forth in the Limited Guarantee, the WM Guarantee and the Equity Commitment Letter, (a) each Contracting Party hereby waives and releases any and all rights, claims, demands, or causes of action that may otherwise be available at law or in equity, or granted by statute, to avoid or disregard the entity form of a Contracting Party or otherwise impose liability of a Contracting Party on any Nonparty Affiliate, whether granted by statute or based on theories of equity, agency, control,

instrumentality, alter ego, domination, sham, single business enterprise, piercing the veil, unfairness, undercapitalization, or otherwise; and (b) each Contracting Party disclaims any reliance upon any Nonparty Affiliates with respect to the performance of this Agreement or any representation or warranty made in, in connection with, or as an inducement to this Agreement.

Section 10.15 Expenses. Except as otherwise provided in this Agreement, each of the parties shall bear its own expenses incurred in connection with the negotiation and execution of this Agreement and each other agreement, document and instrument contemplated by this Agreement and the consummation of the transactions contemplated hereby and thereby. Notwithstanding the foregoing, all Company Transaction Expenses shall be paid by the Sellers.
