(ii)If Seller Parent disputes the accuracy of any calculations set forth on the Closing Statement, Seller Parent shall provide written notice to Purchaser no later than thirty (30) days following the delivery by Purchaser to Seller Parent of the Closing Statement (the “Dispute Notice”), setting forth in reasonable detail those items that Seller Parent disputes, which shall be limited to mathematical errors and whether calculations of amounts are in accordance with the Accounting Principles and the terms of this Agreement. If given, the Dispute Notice will set forth any proposed adjustment to the Closing Statement. During the thirty (30)-day period following delivery of a Dispute Notice, Purchaser and Seller Parent shall negotiate in good faith with a view to resolving their disagreements over the disputed items. During such thirty (30)-day period and until the final determination of Final Working Capital, Final Cash, Final Indebtedness and/or Final Company Transaction Expenses in accordance with this Section 2.5(c)(ii), Seller Parent and its agents shall be provided with such access to the financial books and records of the Acquired Companies and Purchaser as Seller Parent and its agents may reasonably request to enable Seller Parent and its agents to address all matters set forth in any Dispute Notice. If the Parties resolve their differences over the disputed items in accordance with the foregoing procedure, “Final Working Capital,” “Final Cash,” “Final Indebtedness” and/or “Final Company Transaction Expenses” shall be the amounts agreed upon by them. If the Parties fail to resolve their differences over the disputed items within such thirty (30)-day period, then Purchaser and Seller Parent shall forthwith jointly request that Deloitte Touche Tohmatsu Limited (the “Accounting Arbitrator”) make a binding determination as to the unresolved disputed items in accordance with Section 2.5(c)(iii).

(iii)The Accounting Arbitrator will, under the terms of its engagement, have no more than thirty (30) days from the date of referral and no more than ten (10) Business Days from the final submission of information and testimony by Purchaser and Seller Parent within which to render its written decision with respect to the disputed items (and only with respect to any unresolved disputed items set forth in the Dispute Notice) and the final calculation of Closing Working Capital, Closing Cash, Closing Indebtedness and/or Closing Company Transaction Expenses shall be based solely on the resolution of such disputed items. The Accounting Arbitrator shall review such submissions and base its determination solely on such submissions. The Accounting Arbitrator shall be bound by and apply only the Accounting Principles and may not assign a value to any item greater than the maximum value for such item claimed by either Party or less than the minimum value for such item claimed by either Party. The decision of the Accounting Arbitrator shall be deemed final and binding upon the Parties and enforceable by any court of competent jurisdiction and the Accounting Arbitrator’s final calculation of Closing Working Capital shall be deemed the “Final Working Capital,” the Accounting Arbitrator’s final calculation of Closing Cash shall be deemed the “Final Cash,” the Accounting Arbitrator’s final calculation of Closing Indebtedness shall be deemed the “Final Indebtedness” and/or the Accounting Arbitrator’s final calculation of Closing Company Transaction Expenses shall be deemed the “Final

Exhibit 2.1

Company Transaction Expenses”. The fees and expenses of the Accounting Arbitrator shall be allocated to be paid by Purchaser, on the one hand, and Seller Parent, on behalf of Sellers, on the other hand, based upon the percentage that the portion of the contested amount not awarded to each Party bears to the amount actually contested by such Party, as determined by the Accounting Arbitrator.

(d)Payment following Calculation of Final Working Capital, Final Cash, Final Indebtedness and Final Company Transaction Expenses.

(i)Following the determination of the Final Working Capital, the Final Cash, the Final Indebtedness and the Final Company Transaction Expenses, the Purchase Price shall be recalculated substituting the Final Working Capital for the Estimated Working Capital in Section 2.2(a)(v) or Section 2.2(a)(vi), as applicable, the Final Cash for the Estimated Cash in Section 2.2(a)(ii), the Final Indebtedness for the Estimated Indebtedness in Section 2.2(a)(iii) and the Final Company Transaction Expenses for the Estimated Company Transaction Expenses in Section 2.2(a)(iv) (the “Final Purchase Price”) and if (after taking into account any Downward Working Capital Adjustment at the Closing) (a) the Final Purchase Price is greater than the Purchase Price on the Closing Date, then such difference shall be paid (or caused to be paid) by Purchaser to Sellers in the amounts and to the accounts specified in writing by Seller Parent and (b) the Purchase Price on the Closing Date is greater than the Final Purchase Price, then such difference shall be paid by Seller Parent to Purchaser.

(ii)All payments pursuant to this Section 2.5(d) shall be made in cash in immediately available funds by wire transfer to an account or accounts designated in advance by Seller Parent or Purchaser, as applicable, and shall be made on or prior to the fifth (5th) Business Day after the first to occur of the following: (A) the 30-day period following Purchaser’s delivery of the Closing Statement if Seller Parent does not timely dispute any of the amounts set forth thereon pursuant to Section 2.5(c)(ii) or if Seller Parent accepts the Closing Statement within thirty (30) days pursuant to Section 2.5(c)(i); (B) the date of Seller Parent’s and Purchaser’s mutual determination of the Final Working Capital, the Final Cash, the Final Indebtedness and the Final Company Transaction Expenses in the event Seller Parent timely disputes any of such amounts pursuant to Section 2.5(c)(i) and Seller Parent’s and Purchaser’s differences are resolved without the engagement of the Accounting Arbitrator pursuant to Section 2.5(c)(ii); or (C) the date of the Accounting Arbitrator’s determination of the Final Working Capital, the Final Cash, the Final Indebtedness and/or the Final Company Transaction Expenses pursuant to Section 2.5(c)(iii) in the event Seller Parent timely disputes any of such amounts pursuant to Section 2.5(c)(i) and Seller Parent and Purchaser are unable to resolve their differences pursuant to Section 2.5(c)(ii).

(e)Nothing in this Section 2.5 will require any Party or its Affiliates to provide the other Party or its Affiliates with access to or copies of information the disclosure of which would jeopardize any attorney-client or attorney work product privilege (provided that each Party will use commercially reasonable efforts to provide such information in a manner that does not jeopardize such privilege).

2.6 Purchase Price Allocation.

(a)No later than ten (10) Business Days prior to the Closing Date, Seller Parent will allocate the Purchase Price (along with the Assumed Liabilities and any other amounts treated as consideration for U.S. Federal income Tax purposes) among the Interests, the Transferred Proprietary Rights (including the Mexican Transferred Proprietary Rights) and the Shares (the “Preliminary Allocation”); provided, however, the Parties agree that in no event shall more than $25,000,000 be allocated among the Shares and the Mexican Transferred Proprietary Rights and the Seller Note will not

Exhibit 2.1

include any amounts allocated to the Shares and the Mexican Transferred Proprietary Rights . If Purchaser disagrees with the Preliminary Allocation provided by Seller Parent, Purchaser and Seller Parent shall jointly revise the Preliminary Allocation in a manner reasonably acceptable to both parties. If Purchaser and Seller Parent are unable to agree on the portion of the Purchase Price to be allocated to the Mexican Transferred Proprietary Rights, then the disputed items shall be resolved by the Accounting Arbitrator in accordance with the procedures set forth in Section 2.5(c)(iii), whose determination shall be final and binding on the parties; provided, however, that in no event will more than $25,000,000 be allocated among the Shares and the Mexican Transferred Proprietary Rights or will the Seller Note include any amounts allocated to the Shares and the Mexican Transferred Proprietary Rights pursuant to this Section 2.6(a). The Accounting Arbitrator shall use reasonable efforts to resolve the dispute within thirty (30) days after the item has been referred to it. The costs, fees and expenses of the Accounting Arbitrator shall be borne in the manner described in Section 2.5(c)(iii). The Preliminary Allocation (including any revisions thereto) will be final and binding upon the parties solely for purposes of any payments contemplated by Section 2.5(c)(iii).

(b)Within ninety (90) days after the final determination of the Final Purchase Price under Section 2.5 hereunder, Purchaser shall allocate for U.S. federal income tax purposes (x) the Final Purchase Price (together with any Assumed Liabilities or other items properly treated as purchase price for U.S. federal income Tax purposes) among the Interests, the Transferred Proprietary Rights and the Shares and (y) thereafter, (i) if the Section 338(h)(10) Elections are made pursuant to Section 5.12(g), the aggregate amount allocated to the Interests shall be further allocated among assets of the Company and (ii) if a Section 338(g) Election is made with respect to the Shares, the aggregate amount allocated to the Shares of Harsco Mexico, shall be further allocated among assets of Harsco Mexico (the allocation calculated in (x) and (y), the “Proposed Allocation”). Purchaser shall promptly provide a copy of the Allocation to Seller Parent. Seller Parent shall have a period of fifteen (15) Business Days after the delivery of the Proposed Allocation (the “Response Period”) to notify Purchaser of any objections Seller Parent may have to the allocations set forth therein (an “Objection Notice”). Unless Seller Parent objects to the Proposed Allocation within the Response Period, the Proposed Allocation shall be binding on the parties without further adjustment.

(c)If Seller Parent shall raise any objections within the Response Period, Purchaser and Seller Parent shall negotiate in good faith and use their reasonable best efforts to resolve such dispute. If the parties fail to agree within fifteen (15) Business Days after the delivery of the Objections Notice, then the disputed items shall be resolved by the Accounting Arbitrator in accordance with the procedures set forth in Section 2.5(c)(iii), whose determination shall be final and binding on the parties. The Accounting Arbitrator shall use reasonable efforts to resolve the dispute within thirty (30) days after the item has been referred to it. The costs, fees and expenses of the Accounting Arbitrator shall be borne in the manner described in Section 2.5(c)(iii).

(d)The final allocation shall be amended to reflect any purchase price adjustments hereunder. Seller Parent and Purchaser shall and each shall cause its Affiliates to (A) report the transactions contemplated by this Agreement for Tax purposes (including Section 1060 of the Code) in accordance with the allocation (as so amended) as finally determined under this Section 2.6 and (B) not take any position inconsistent with such final allocation (as so amended) on any of their respective Tax Returns unless otherwise required by a “determination” within the meaning of Section 1313 of the Code (or any similar provision of state, local or non-U.S. Law) or in connection with the settlement of any audit or other claim with a Taxing Authority.

2.7 Withholding. Each Seller shall pay all Taxes that as Seller it is required to pay in connection with this Agreement and/or the Transaction Documents under Applicable Law. Purchaser shall

Exhibit 2.1

be entitled to deduct and withhold from any amounts otherwise payable pursuant to this Agreement such amounts as are required to be deducted and withheld under Applicable Tax Law. Except for any amounts that are treated as compensation or are withheld by reason of the failure to provide the certificate described in Section 2.4(c)(iii), if Purchaser believes that any withholding of Tax is required with respect to any payment under this Agreement, then Purchaser shall use commercially reasonable efforts to give notice to Seller Parent describing the basis for such withholding in reasonable detail at least five (5) Business Days before the Closing Date, Purchaser shall provide Seller Parent with a reasonable opportunity to provide any applicable certificate, form or documentation that would reduce or eliminate the requirement to deduct and withhold Tax with respect to such payment, and Purchaser shall otherwise cooperate with the applicable Seller and take such steps as Seller Parent may reasonably request to reduce or eliminate such withholding obligation to the extent permitted by Applicable Law. To the extent that amounts are so deducted and withheld pursuant to this Section 2.7, such deducted and withheld amounts (i) shall be timely remitted by Purchaser to the applicable Taxing Authority and (ii) upon remittance, shall be treated for all purposes of this Agreement as having been paid to the Person in respect of which such deduction and withholding was made.

For purposes of this Section 4.9, “Solvent” means that, with respect to any Person and as of any date of determination, (a) the amount of the “present fair saleable value” of the assets of such Person, will, as of such date, exceed the amount of all “liabilities of such Person, contingent or otherwise,” as of such date, as such quoted terms are generally determined in accordance with applicable federal laws governing determinations of the insolvency of debtors, (b) the present fair saleable value of the assets of such Person will, as of such date, be greater than the amount that will be required to pay the liability of such Person on its indebtedness as its indebtedness becomes absolute and matured, (c) such Person will not have, as of such date, an unreasonably small amount of capital with which to conduct its business, (d) such Person will be able to pay its indebtedness as it matures, and (e) such Person will be solvent as determined by the applicable

Exhibit 2.1

laws of the jurisdiction of incorporation of such Person. For purposes of the foregoing definition only, “indebtedness” means a liability in connection with another Person’s (x) right to payment, whether or not such a right is reduced to judgment, liquidated, unliquidated, fixed, contingent, matured, unmatured, disputed, undisputed, legal, equitable, secured or unsecured or (y) right to any equitable remedy for breach of performance if such breach gives rise to a right of payment, whether or not such right to an equitable remedy is reduced to judgment, fixed, contingent, matured, unmatured, disputed, undisputed, secured or unsecured.

4.10 Plant Closings and Mass Layoffs. Purchaser does not currently plan or contemplate any plant closings, reductions in force, or terminations of Employees that, in the aggregate, would trigger the WARN Act or any other similar law, rule or regulation of any Governmental Authority.

4.11 Affiliate Guarantee. Concurrently with the execution of this Agreement, Purchaser has delivered to Sellers a guarantee, dated the date hereof and in the form attached hereto as Exhibit J, of KPS Special Situations Mid-Cap Fund LP and KPS Special Situations Mid-Cap Fund (A) LP (the “Affiliate Guarantors”) guaranteeing certain of Purchaser’s obligations hereunder (the “Affiliate Guarantee”) upon and subject to the terms and conditions of the Affiliate Guarantee. The Affiliate Guarantee is in full force and effect and is a valid, legal, binding and Enforceable obligation of the applicable Affiliate Guarantor. No event has occurred which, with or without notice, lapse of time or both, would constitute a default on the part of the Affiliate Guarantors under the Affiliate Guarantee. Nothing in this Section 4.11 shall be construed to limit in any way either Seller’s right to seek an injunction or injunctions to prevent breaches of this Agreement and to enforce specifically the terms and provisions of this Agreement as contemplated by Section 9.13.

4.12 No Other Representations; No Reliance. Purchaser is an informed and sophisticated purchaser, and has engaged advisors, experienced in the evaluation and purchase of companies such as the Acquired Companies as contemplated hereunder.

Exhibit 2.1

stock exchange rules, in which case the Party required to publish such press release or make such public announcement or disclosure shall allow each other Party a reasonable opportunity to comment on such press release, public announcement or disclosure in advance of such publication or disclosure, to the extent practicable.

(i)Each Party and its Affiliates (after the Closing, such Affiliates of Purchaser shall include the Acquired Companies) shall have the right and remedy, without regard to any other available remedy, to (A) have the Restrictive Covenants specifically enforced by any court of competent jurisdiction and (B) have issued an injunction restraining any such breach without posting of a bond; it being understood that any breach of any of the Restrictive Covenants would cause irreparable and material losses to Purchaser and its Affiliates (after the Closing, such Affiliates to include the Acquired Companies), the amount of which cannot be readily determined and as to which neither non-breaching Party nor any of its Affiliates (after the Closing, such Affiliates of Purchaser shall include the Acquired Companies) will have any adequate remedy at law or in damages;

(ii)it is the desire and intent of the Parties that the Restrictive Covenants be enforced to the fullest extent permissible under the laws and public policies applied in each jurisdiction in which enforcement is sought and if any Restrictive Covenant shall be adjudicated finally to be invalid or unenforceable, such Restrictive Covenant shall be deemed amended to the extent necessary in order that such provision be valid and enforceable, the remainder of such Restrictive Covenant shall not thereby be affected and shall be given full effect without regard to invalid portions and such amendment shall apply only with respect to the operation of the Restrictive Covenant in the particular jurisdiction in which such adjudication is made; and

(iii)the Parties acknowledge and agree that the Restrictive Covenants are necessary for the protection and preservation of the value and the goodwill of the Sellers’ and Purchaser’s and the Acquired Companies’ businesses, respectively, and are reasonable and valid in geographical and temporal scope and in all other respects.

For the avoidance of doubt, each Seller shall retain all rights to control its and its Affiliates’ insurance policies and

Exhibit 2.1

programs, including the right to exhaust, settle, release, commute, buy back or otherwise resolve disputes with respect to any of its insurance policies and programs, notwithstanding whether any such policies or programs apply to any liabilities of Purchaser or any of its Affiliates.

(b)Notwithstanding Section 5.11(a):

(i)Seller Parent shall, and shall cause its Subsidiaries to, (i) use commercially reasonable efforts to maintain the coverage provided to any Acquired Company through Seller Parent’s or its Subsidiaries’ third-party insurance policies (the “Seller Parent Insurance Policies”), in full force and effect until the Closing, and (ii) prior to the Closing, report to the applicable third-party insurance provider under each such applicable Seller Parent Insurance Policy events, acts, errors, accidents, omissions, incidents, injuries or other forms of occurrences to the extent relating to the Business, any Acquired Company or the properties, assets, operations, employees, officers or directors of the Business or any Acquired Company that, in each case, occur prior to the Closing and are potentially covered by an occurrence-based Seller Parent Insurance Policy (collectively, the “Pre-Closing Occurrences”).

(ii)From and after the Closing Date, (i) Seller Parent shall, and shall cause its Subsidiaries to, use commercially reasonable efforts to report in good faith to the applicable third-party insurance provider all Pre-Closing Occurrences reasonably requested by Purchaser and otherwise reasonably cooperate with the Acquired Companies to reasonably ensure that applicable claim reporting and other applicable material Seller Parent Insurance Policy requirements are met, in each case with respect to Pre-Closing Occurrences, (ii) Purchaser shall cause the Acquired Companies to comply with the terms of the applicable Seller Parent Insurance Policy, (iii) subject to Article 8, the Acquired Companies shall be fully liable for all deductibles and uninsured or self-insured amounts in respect of any Pre-Closing Occurrence, and (iv) Seller Parent shall, and shall cause its applicable Subsidiaries to, use commercially reasonable efforts to obtain the benefit of the applicable insurance coverage under any applicable Seller Parent Insurance Policy and pay such benefit to the Acquired Companies, net of any co-payments or other reasonable out-of-pocket costs and expenses (including reasonable legal fees and expenses, if any) reasonably incurred by Seller Parent and its Subsidiaries in seeking such insurance proceeds (collectively, “Recovery Costs”); provided, that if the Recovery Costs are greater than the applicable benefit payable to the Acquired Companies, the Acquired Companies shall promptly reimburse Seller Parent and its Subsidiaries for such difference. After the Closing, except for the erosion of policy limits through payments under the policy, Seller Parent shall not, and shall cause its Subsidiaries to not, release, commute, buy-back or otherwise eliminate (whether in whole or in part) insurance coverage under any of the applicable Seller Parent Insurance Policies with respect to any such Pre-Closing Occurrences.

(iii)Notwithstanding any provision of Section 5.11(b)(ii) to the contrary, with respect to each known Pre-Closing Occurrence as of the Closing and each reported Pre-Closing Occurrence as of the Closing, in each case potentially covered by a third-party claims-made insurance policy of Seller Parent or its Subsidiaries (excluding the Acquired Companies) (each such policy, a “Seller Parent Claims-Made Policy” and each such claim, a “Covered Known Claim”), Seller Parent shall use commercially reasonable efforts in good faith to obtain insurance coverage for such Covered Known Claim under the Seller Parent Claims-Made Policies as though such Seller Parent Claims-Made Policy were a Seller Parent Insurance Policy, mutatis mutandis (including, for the avoidance of doubt, Seller will be entitled to the netting and reimbursement of Recovery Costs).

5.12 Tax Matters. The following provisions shall govern the allocation of responsibility as between Purchaser and Sellers for certain Tax matters following the Closing Date:

Exhibit 2.1

(a)Responsibility for Filing Tax Returns.

(i)Sellers shall prepare in a manner consistent with past practice and timely file any Pre-Closing Separate Return that is required by Applicable Law to be filed on or before the Closing Date and shall timely pay, or cause to be paid, to the relevant Taxing Authority the amount shown as due on such Pre-Closing Separate Return.

(ii)In the case of any Pre-Closing Separate Return for Income Taxes that is required by Applicable Law to be filed after the Closing Date, Sellers shall prepare, or cause to be prepared, in a manner consistent with past practice such Pre-Closing Separate Return (except as otherwise required by Applicable Law) and deliver any such Pre-Closing Separate Return related to Income Taxes (or substantially completed drafts of such Pre-Closing Separate Returns) to Purchaser for review and comment at least 30 Business Days before it is due. Sellers shall consider in good faith Purchaser’s reasonable comments received by Sellers within 10 Business Days of Purchaser’s receipt of such Pre-Closing Separate Return in the case of a Pre-Closing Separate Return for Income Taxes and, to the extent necessary, deliver an amended Pre-Closing Separate Return to Purchaser. Purchaser shall file, or cause to be filed, such amended Pre-Closing Separate Return with the relevant Taxing Authority. In the case of any material Pre-Closing Separate Return that is not for Income Taxes and that is required by Applicable Law to be filed after the Closing Date, Purchaser shall prepare, or cause to be prepared, in a manner consistent with past practice such Pre-Closing Separate Return (except as otherwise required by Applicable Law) and deliver any such Pre-Closing Separate Return (or substantially completed drafts of such Pre-Closing Separate Returns) to Sellers for review and comment within a reasonable period of time (and in any event no later than three (3) Business Days) before it is due. With Sellers’ consent (which consent shall not be unreasonably withheld, conditioned or delayed), Purchaser shall file, or cause to be filed, such Pre-Closing Separate Return with the relevant Taxing Authority; provided, that in all cases Purchaser shall be entitled to file such Pre-Closing Separate Returns on or prior to the date that they are due but shall amend any such Pre-Closing Separate Returns after they are filed if such amendment is reasonably requested by Sellers. All reasonable out-of-pocket expenses of Purchaser related to such amendment shall be paid by Sellers.

(iii)Purchaser shall prepare, or cause to be prepared, in a manner consistent with past practice (except as otherwise required by applicable Law) all Tax Returns required to be filed by or with respect to each Acquired Company for any Straddle Period, other than a Tax Return with respect to a Seller Consolidated Group (the “Straddle Period Tax Returns”). Purchaser shall deliver any such Straddle Period Tax Return related to Income Taxes and any other such material Straddle Period Tax Return (or substantially completed drafts of such Straddle Period Tax Returns) to Sellers for review and comment (i) at least 30 Business Days before it is due in the case of a Straddle Period Tax Return for Income Taxes or (ii) within a reasonable period of time (and in any event no later than 3 Business Days) before it is due in the case of a material Straddle Period Tax Return (for Taxes other than Income Taxes). Purchaser shall consider in good xxxxx Xxxxxxx’ reasonable comments relating to the Pre-Closing Tax Period received by Purchaser within either (y) 10 Business Days after Sellers received such Straddle Period Tax Return from Purchaser in the case of a Straddle Period Tax Return for Income Taxes or (z) a reasonable period of time before it is due in the case of a material Straddle Period Tax Return for Taxes other than Income Taxes, and, to the extent necessary, deliver an amended Straddle Period Tax Return to Sellers. Purchaser shall file, or cause to be filed, such amended Straddle Period Tax Return with the relevant Taxing Authority; provided, that if Sellers and Purchaser are unable to resolve any dispute relating to the content of a Straddle Period Tax Return after Purchaser has considered Sellers’ comments in good faith, the item or items in dispute shall be resolved by the Accounting Arbitrator and the dispute resolution procedure of Section 2.5 shall govern. The costs, fees and expenses of the Accounting Arbitrator shall be

Exhibit 2.1

borne in the manner described in Section 2.5(c)(iii). If any dispute pursuant to this Section 5.12(a)(iii) is not resolved by the time the relevant Straddle Period Tax Return is due, Purchaser shall timely file such Straddle Period Tax Return in its discretion, but any payments required pursuant to this Agreement with respect to such Straddle Period Tax Return shall be based on the final resolution of the dispute; provided, that Purchaser shall provide Sellers with a copy of any Straddle Period Tax Return not submitted to Seller for review pursuant to this Section 5.12(a)(iii) no later than ten (10) Business Days after filing such Straddle Period Tax Return.

(iv)At least two Business Days before the due date of any Pre-Closing Separate Return filed after the Closing Date or any Straddle Period Tax Return, Sellers shall pay to Purchaser the amount for which Sellers have an indemnification obligation pursuant to Section 8.3.

(b)Allocation of Taxes in Straddle Periods. Taxes (other than Transfer Taxes) payable with respect to a Straddle Period shall be allocated between the Pre-Closing Tax Period and the post-Closing Tax Period (i) in the case of Taxes imposed on a periodic basis (such as real, personal and intangible property Taxes), the amount allocated to the Pre-Closing Tax Period shall be the amount of such Taxes for the entire Straddle Period multiplied by a fraction, the numerator of which is the number of calendar days of such Straddle Period in the Pre-Closing Tax Period and the denominator of which is the number of calendar days in the entire Straddle Period, and (ii) in the case of other Taxes, as if the Tax period ended as of the close of business on the Closing Date and, in the case of any such other Taxes that are attributable to the ownership of any equity interest in a “controlled foreign corporation” (within the meaning of Section 957(a) of the Code or any comparable Applicable Law), as if the Tax period of that entity ended as of the close of business on the Closing Date.

(c)Refunds and Amended Returns.

(i)Any refunds of Taxes (including estimated Taxes) with respect to any Pre-Closing Tax Period (other than any refunds that were included in the calculation of the Final Purchase Price) that are received by Purchaser or the Acquired Companies after the Closing Date (any such refund, a “Pre-Closing Tax Refund”), shall be for the account of the Sellers, and Purchaser or the Acquired Companies shall pay over to the Sellers any such Pre-Closing Tax Refund within ten (10) days after receipt thereof net of any reasonable out-of-pocket costs (including Taxes) incurred by the Purchaser or the Acquired Companies in connection with the receipt of such Pre-Closing Tax Refund. At Seller Parent’s reasonable request, Purchaser and the Acquired Companies shall cooperate with Seller Parent (on behalf of the Sellers) in obtaining any Pre-Closing Tax Refund, including through the filing of amended Tax Returns or refund claims, it being understood that (i) all Pre-Closing Tax Refunds shall be claimed in cash rather than as a credit against future Tax liabilities if permitted by Applicable Law and (ii) Seller Parent will bear any out-of-pocket costs incurred by Purchaser or the Acquired Companies in connection with any such request.

(ii)Amended Returns. Unless required by Applicable Law, Purchaser shall not cause the Acquired Companies to file any Tax Return that relates to any Pre-Closing Tax Period without the consent of the Sellers (such consent not to be unreasonably withheld, delayed or conditioned).

(d)Cooperation on Tax Matters. Purchaser and the Sellers shall cooperate fully, as and to the extent reasonably requested by any party, in connection with the filing of Tax Returns pursuant to this Section 5.12 and any audit, litigation or other proceeding, including any proceeding before the Mexican Taxpayers Advocacy Agency (Procuraduría de la Defensa del Contribuyente) with respect to Taxes. Such cooperation shall include the retention and (upon the other party’s request) the provision of records and information which are reasonably relevant to any such Tax Return, audit,

Exhibit 2.1

litigation or other proceeding and making employees and outside consultants and advisors available on a mutually convenient basis to provide additional information and explanation of any material provided hereunder. Purchaser and the Sellers agree (x) to retain all books and records in their possession with respect to Tax matters pertinent to the Acquired Companies relating to any taxable period beginning before the Closing Date until the expiration of the statute of limitations (and, to the extent notified by Purchaser or the Sellers, any extensions thereof) of the respective taxable periods, and to abide by all record retention agreements entered into with any Taxing Authority, and (y) to give the other Party reasonable written notice prior to transferring, destroying or discarding any such books and records and, if the other so requests, Purchaser or the Sellers, as the case may be, shall allow the other to take possession of such books and records. Any information obtained under this Section 5.12(d) shall be kept confidential, except as may be otherwise necessary in connection with the filing of Tax Returns or in the conduct of a Tax Proceeding.

(e)Purchaser Covenants.

(i)Unless required by Applicable Law, Purchaser shall not make or change any Tax election, amend any Tax Return, or take any Tax position on any Tax Return that results in any increased Tax liability or reduction of any Tax Asset (defined below) in respect of any Pre-Closing Tax Period. On the Closing Date, Purchaser shall not cause or permit the Companies or any Affiliate of Purchaser to effect any extraordinary transactions (including, but not limited to, the distribution of any dividend or the effectuation of any redemption, but excluding any Contemplated Transactions) that could give rise to any Tax liability or reduce any Tax Asset of the Sellers or the Acquired Companies. For purposes of this Agreement, the term “Tax Asset” means any net operating loss, net capital loss, investment tax credit, foreign tax credit, charitable deduction or any other credit or tax attribute that could be carried forward or back to reduce Taxes (including deductions and credits related to alternative minimum Taxes) and losses or deductions deferred by the Code or other Applicable Law.

(ii)Any payments under this Agreement shall be treated by all Parties as adjustments to the Final Purchase Price.

(f)Transfer Taxes. Notwithstanding anything to the contrary herein, all transfer, documentary, sales, use, stamp, registration and other similar non-recoverable Taxes, and all conveyance fees, recording charges and other similar fees and charges (including any penalties and interest) (“Transfer Taxes”) incurred in connection with consummation of the Contemplated Transactions shall be paid half by Sellers and half by Purchaser when due, and Purchaser and Seller Parent will, at its own expense, file all necessary Tax Returns and other documentation required to be filed by it with respect to all such Taxes, fees and charges, and, if required by Applicable Law, Sellers and Purchaser, as applicable, will join in the execution of any such Tax Returns and other documentation.

(g)Section 338(h)(10) Election.

(i)At Purchaser’s request, Seller Parent and Purchaser shall jointly make an election under Section 338(h)(10) of the Code with respect to the acquisition of the Company and any corresponding elections under state or local Tax law (collectively, the “Section 338(h)(10) Elections”) in accordance with applicable Tax laws and as set forth herein and shall timely execute Forms 8023 and such other forms as may be necessary to effect such Section 338(h)(10) Elections (the “Section 338 Forms”).

(ii)Purchaser shall be responsible for the preparation and filing of all Section 338 Forms in accordance with applicable Tax laws and the terms of this Agreement. Seller Parent

Exhibit 2.1

and Purchaser shall execute and deliver to one another such documents or forms as are reasonably requested and are required by any Tax laws properly to complete the Section 338 Forms.

(iii)If Purchaser requests that Sellers join a Section 338(h)(10) Election, after completion of the final purchase price allocation pursuant to Section 2.6, Purchaser shall deliver to Seller Parent completed copies of IRS Form 8883 and required schedules thereto. Purchaser shall act in good faith to determine the amount of the aggregate deemed sales price (“ADSP”) (within the meaning of Treas. Reg. §1.338(h)(10)-1(d)(3) and §1.338-4) and the proper allocations (the “Allocations”) of the ADSP among the assets of the Acquired Companies in accordance with Treas. Reg. §1.338(h)(10)-1(d)(3), §1.338-6, and §1.338-7. The allocation of the Final Purchase Price among the assets of the Company shall be made in accordance with Section 2.6 (the “Section 338 Allocation Schedule”). Purchaser and Seller Parent will, subject to the requirements of any applicable Tax law or election, file all Tax Returns and reports consistent with the Section 338 Forms and the Section 338 Allocation Schedule. Any adjustments to Final Purchase Price will be allocated in a consistent manner.

(iv)Seller Parent and Purchaser agree that, except as required by a final determination with any Taxing Authority, they will report the transfers under this Agreement consistent with the Section 338(h)(10) Elections, if made, and will not take, or cause to be taken, any action in connection with the filing of any Tax return on behalf of Seller Parent and Purchaser or their Affiliates or otherwise that would be inconsistent with or prejudice the Section 338(h)(10) Elections or this Section 5.12(g), and they will take all steps necessary to obtain comparable treatment, where applicable, for state income Tax purposes.

(h)Tax Sharing Agreements Sellers shall cause all Tax sharing or indemnification agreements (other than agreements entered into in the ordinary course of business the primary purpose of which is not the allocation or sharing of Taxes) between or among Sellers or any of their Subsidiaries (other than any Acquired Company), on the one hand, and any Acquired Company, on the other hand, to terminate on or before the Closing Date.

(i)Treasury Regulation Section 1.1502-36 Election. In the event that Sellers or any Affiliate recognizes a loss on a sale of any Acquired Company in the Contemplated Transactions that, absent an election to the contrary, would result in a reduction in the “Category D attributes” (as defined in Treasury Regulations Section 1.1502-36) of any Acquired Company pursuant to Treasury Regulations Section 1.1502-36(d)(4)(ii), Sellers shall, or shall cause the relevant Affiliate or the applicable common parent of their consolidated group to, make an effective election pursuant to Treasury Regulations Section 1.1502-36(d)(6) so that no such reduction in “Category D attributes” shall occur. Purchaser and Sellers shall, and shall cause their respective Affiliates to, cooperate in good faith in connection with determining whether an election is required pursuant to this Section 5.12(i). Seller shall timely provide Purchaser with a copy of the “Section 1.1502-36 Statement”, if any, filed in connection with any election made under this Section 5.12(i).

(j)Tax Proceedings.

(i)Seller Parent or its designee shall have the right to elect to control any Tax Proceeding on behalf of the Acquired Companies that relates primarily to any Seller Indemnified Taxes (each, a “Seller Tax Proceeding”); provided, however, that Seller Parent or its designee shall not settle any such Seller Tax Proceedings without the prior written consent of Purchaser, which consent shall not be unreasonably withheld, conditioned, or delayed. Purchaser shall promptly notify Seller Parent in writing upon receiving notice from any Taxing Authority of the commencement of any Seller Tax Proceedings, and Purchaser shall take all actions reasonably necessary (including providing a power of

Exhibit 2.1

attorney) to enable Seller Parent or its designee to exercise its control rights as set forth in this Section 5.12(j)(i); provided, however, that a failure to give such notice will not affect Purchaser’s rights to indemnification under Article 8, except to the extent that Seller is actually prejudiced thereby.

(ii)In the case of any Tax Proceeding of or relating to a Straddle Period that would reasonably be expected to give rise to any Tax for any Post-Closing Tax Period (or portion thereof), Purchaser or its designee shall have the right to control such Tax Proceeding by notifying Seller Parent within ten (10) Business Days of receiving notice of such Tax Proceeding. Purchaser shall keep Seller Parent reasonably informed with respect to any material developments or communications (including telephonic communications) related to such Tax Proceeding, (ii) provide Seller Parent with the right, at Seller Parent’s sole expense, to participate in such Tax Proceeding (to the extent permitted by the applicable Taxing Authority) and (iii) not settle such Tax Proceeding without the prior written consent of Seller Parent, which consent shall not be unreasonably withheld, conditioned or delayed.

(iii)If Seller Parent or its designee fail, after receiving notice from Purchaser pursuant to Section 5.12(j)(i), to timely control any Tax Proceeding (x) for which Sellers have an indemnification obligation pursuant to Section 8.1 and (y) that are not related to a Seller Consolidated Group, Purchaser or its designee shall control such Proceeding.

(k)Section 338(g) Election. Purchaser intends to make an election under Section 338(g) of the Code with respect to the acquisition of Harsco Mexico and any corresponding elections under state or local Tax law (collectively, the “Section 338(g) Election”). Purchaser shall notify Sellers if it decides not to make such Section 338(g) election after the deadline for timely filing the Section 338(g) Election has passed.

5.13 No Contacts. Prior to the Closing, without the prior written consent of Seller Parent, Purchaser shall not, directly or indirectly through its Representatives or otherwise, contact or communicate with the employees, customers, suppliers or any other Person with a material business relationship with the Acquired Companies in connection with the Contemplated Transactions.

Exhibit 2.1

similarly situated employees of Purchaser and its Affiliates, in the case of each such calendar year, after giving pre-Closing vacation service credit for each Transferred Employee.

(i)Bonuses and Incentive Compensation. Except for any retention benefits provided for under the Retention Agreements that are owed to the Transferred Employees as a result of the consummation of the Contemplated Transactions and ordinary course payroll compensation of the Transferred Employees accrued as of the Closing Date, Purchaser and its Affiliates shall, effective as of the Closing, assume Liability for all bonuses and incentive compensation payments accrued and vested as of the Closing Date (including within the timing and form specified for payment therefor) pursuant to each Seller Benefit Plan for all Transferred Employees and Transferred Union Employees. Notwithstanding anything to the contrary contained in that certain Leased Employee Services Agreement, Seller Parent shall pay to the US Employees who become Transferred Employees all retention benefits provided for under the Retention Agreements that are owed to the Transferred Employees as a result of the consummation of the Contemplated Transactions. Seller or its designated Affiliates will retain all assets and Liabilities related to the Seller Benefit Plans except with respect to the Assumed Employee Liabilities and Assumed Pension Liabilities.

5.15 Employee Benefits.

(a)Without limiting Purchaser’s obligations pursuant to Section 5.14, effective on the Closing Date at the applicable time provided in Section 2.4(a), and for the duration of the Transition Period, Purchaser and its Affiliates shall provide the Transferred Employees and the Transferred Union Employees with employee benefits that satisfy the requirements of this Section 5.15. Purchaser agrees to use commercially reasonable efforts to ensure that the Transferred Employees and the Transferred Union Employees shall be eligible immediately to commence participation in the Purchaser Benefit Plans without regard to any eligibility period, waiting period, elimination period, evidence of insurability requirements or pre-existing condition limitations, except for any specific category, or type of employee benefits for which a Collective Bargaining Agreement requires Purchaser to contribute to an Employee Benefit Plan that is maintained or administered by any labor union, labor organization, or similar Person (collectively, any “Union-Administered Benefit Plan”), in which case Purchaser shall satisfy all obligations and Liabilities under such Collective Bargaining Agreement with respect to that Union-Administered Benefit Plan. Purchaser further agrees that the Transferred Employees and the Transferred Union Employees shall be eligible to participate in any future benefit plans adopted or maintained by Purchaser or its Affiliates in which other similarly situated employees of Purchaser or its Affiliates are eligible to participate, except for any specific category, or type, of employee benefits for which a Collective Bargaining Agreement requires Purchaser to contribute to a Union-Administered Benefit Plan. Purchaser and its Affiliates will recognize all service of the Transferred Employees with Seller Parent or any of its Affiliates and with any predecessor employer (to the extent such predecessor employer service was taken into account under the applicable Seller Benefit Plans) for all purposes (including for purposes of vesting, eligibility to participate and receive benefits but not, unless otherwise required by Applicable Law or, Collective Bargaining Agreements or the Pension Plan, under any defined benefit pension plan, any retiree medical or other post-employment welfare benefits) under those existing, newly established and future Purchaser Benefit Plans in which the Transferred Employees and Transferred Union Employees are eligible to participate or are enrolled by Purchaser or its Affiliates at any time on or after the Closing Date, or under any Union-Administered Benefit Plan to which a Collective Bargaining Agreement requires Purchaser to contribute. With respect to the Transferred Employees and Transferred Union Employees, Purchaser and its Affiliates further agree to waive deductible and out-of-pocket requirements under the Purchaser Benefit Plans that provide group health benefits and otherwise to give credit under the applicable Purchaser Benefit Plans for amounts paid under a corresponding Seller Benefit

Exhibit 2.1

Plan that provides group health benefits, as though such amounts had been paid in accordance with the terms and conditions of the applicable Purchaser Benefit Plans; provided, however, and only to the extent that, each Transferred Employee and Transferred Union Employee (and his or her dependents and beneficiaries, as applicable) provides appropriate written consent for disclosure to Purchaser or Purchaser Benefit Plans upon their request of any information reasonably necessary for Purchaser and the applicable Purchaser Benefit Plans to implement such waiver and credit. Purchaser further agrees to use commercially reasonable efforts to cause any group term life insurance plan maintained by Purchaser or its Affiliates to waive any medical certification for any Transferred Employee and Transferred Union Employee up to the amount of coverage the Transferred Employee and/or Transferred Union Employee had under the applicable life insurance plan of Seller Parent or its Affiliates (but subject to any limits on the maximum amount of coverage under the life insurance plans of Purchaser and its Affiliates).

(i)As soon as practicable after the Closing Date, and to the extent permitted by Applicable Law, Purchaser shall, for the Transferred Employees and Transferred Union Employees, establish or designate one or more Purchaser Benefit Plans that are defined contribution plans for the benefit of the Transferred Employees and Transferred Union Employees (the “Successor Savings Plan”), and take all necessary action to cause the Successor Savings Plan to be tax-qualified under the applicable provisions of the Code (to the extent the Successor Savings Plan is not so tax-qualified), and make any and all filings and submissions to the appropriate Governmental Authorities required to be made by Purchaser with respect to the establishment or designation of such Successor Savings Plan. Purchaser shall take all actions necessary to allow the Transferred Employees and Transferred Union Employees to make eligible rollover contributions to the Successor Savings Plan of their account balances, including loans, under the savings plans of Seller Parent and its Affiliates as soon as practicable following the Closing.

(ii)As of the Closing Date, the Transferred Employees and Transferred Union Employees shall no longer be active participants in the Seller Benefit Plans, except where a Collective Bargaining Agreement requires Purchaser to contribute to a Union-Administered Benefit Plan for a Transferred Union Employee.

(b)Nothing contained in this Agreement shall confer upon any Transferred Employee or Transferred Union Employee any right to continued employment with Purchaser or its Affiliates, nor shall anything herein interfere with the right of Purchaser or its Affiliates to relocate or terminate the employment of any of the Transferred Employees or Transferred Union Employees at any time after the Closing Date subject to Applicable Laws, except that this Section shall not diminish or negate the “just cause” protections and other terms and conditions set forth in any Collective Bargaining Agreement as applicable to any Transferred Union Employee. Purchaser shall bear the cost and expense of the termination of the employment of any Transferred Employee or Transferred Union Employee after the Closing Date; provided, that the foregoing shall not apply to the termination of employment of any India Employee by the Seller Parent or its Affiliates pursuant to Section 5.14(f) or any China Employee by the Seller Parent or its Affiliates pursuant to Section 5.14(g). For the avoidance of doubt, Seller shall bear the cost and expense of the termination of the employment of any Employee on or prior to the Closing Date. Purchaser and its Affiliates shall, for each Transferred Employee or Transferred Union Employee who, within the Transition Period, (i) is involuntarily terminated by Purchaser or any of its Affiliates without Good Cause, (ii) has his or her compensation or benefits materially reduced other than a reduction by reason of a circumstance that constitutes Good Cause, and such Transferred Employee or Transferred Union Employee elects to terminate his or her employment with Purchaser or its Affiliates, (iii) has a material diminution in his or her position or title, or (iv) elects to terminate his or her employment with Purchaser or its Affiliates following a requirement that such Transferred Employee or Transferred Union

Exhibit 2.1

Employee take an alternative position that requires a Geographic Relocation (or otherwise requires such Transferred Employee or Transferred Union Employee to undergo a Geographic Relocation), provide severance and other separation benefits to each such Transferred Employee or Transferred Union Employee that are at least equal to the severance and other separation benefits such Transferred Employee or Transferred Union Employee would have received under the terms of the applicable severance plan of Seller Parent or its Affiliate immediately prior to the Closing, as detailed on Section 5.15(b) of the Disclosure Schedules.

(c)Purchaser or its Affiliate (as the case may be) shall be responsible for all Liabilities in respect of benefits accrued or that become payable on and after the Closing Date by Transferred Employees and Transferred Union Employees under the Purchaser Benefit Plans, and neither Seller Parent nor any of its Affiliates shall have any Liability with respect thereto. For the avoidance of doubt, Seller Parent shall be responsible for all Liabilities in respect of employee benefits accrued on or prior to the Closing Date by Employees, and neither Purchaser nor any of its Affiliates shall have any Liability with respect thereto.

(d)Effective as of the last day of the month in which the Closing occurs (the “Seller Parent FSA End Date”), the Transferred Employees and the Transferred Union Employees who participate in the Seller Benefit Plan that is a flexible spending account plan (such accounts, the “Seller Parent FSA” and such participants in the Seller Parent FSA, “FSA Participants”) shall no longer be eligible to contribute to the Seller Parent FSA except as otherwise provided by and in accordance with COBRA. Effective as of the Closing Date, to the extent not previously established or already maintained, the Purchaser, or one of its Affiliates, shall establish or maintain a flexible spending account plan which shall (i) permit immediate participation as of the first day of the month immediately following the Closing Date for all FSA Participants and (ii) accept for reimbursement any claims related to the calendar year in which the Closing Date occurs and eligible for reimbursement on the basis of participant elections initially made under the Seller Parent FSA, to the extent such claims have not been previously reimbursed by the Seller Parent. The salary reduction election of FSA Participants under the Seller Parent FSA will be continued by the Purchaser following the Closing Date (and no such FSA Participant shall be able to change such an election as a result of the transactions contemplated by this Agreement). The Seller Parent shall provide to the Purchaser as soon as administratively feasible, but in no event later than ten (10) Business Days following the date of this Agreement, a schedule setting forth the FSA Participants and (x) if applicable, the amount each FSA Participant has elected to contribute to the Seller Parent FSA for the calendar year in which the Closing Date occurs and (y) the account balance of each FSA Participant (the “FSA Balances”). In addition, the Seller Parent shall provide to the Purchaser as soon as administratively feasible, but in no event later than ten (10) Business Days, following the Seller Parent FSA End Date, an updated schedule setting forth the FSA Balance for each FSA Participant as of the Seller Parent FSA End Date. To the extent the FSA Balances in the aggregate are positive, the Seller Parent shall make a payment to the Purchaser equal to the aggregate positive FSA Balances by the fifteenth (15th) Business Day following the Closing Date. To the extent the FSA Balances in the aggregate are negative, the Purchaser shall make a payment to the Seller Parent equal to the aggregate negative FSA Balances by the fifteenth (15th) Business Day following the Closing Date. The Seller Parent shall reasonably cooperate with the Purchaser in order to effectuate the foregoing, including by providing the FSA Participants’ claims history, to the extent permitted by Applicable Law, under the Seller Parent FSA in order to verify the FSA Balances. Notwithstanding the foregoing, no Transferred Employee or Transferred Union Employee who elects COBRA continuation coverage with respect to such Transferred Employee’s or Transferred Union Employee’s flexible spending account under the Seller Parent FSA shall be considered an FSA Participant, and any such Transferred Employee’s or Transferred Union Employee’s flexible spending account balance shall not be an FSA Balance.

Exhibit 2.1

(e)This Agreement is solely for the benefit of the Parties and is not intended to confer upon any other Persons any rights or remedies hereunder. Nothing in this Agreement, express or implied, shall (i) be construed to establish, amend or modify any Benefit Plan or other benefit or compensation plan, program, agreement, policy, contract or arrangement; or (ii) limit the ability of the Seller Parent, Purchaser or any of their respective Affiliates to amend, modify or terminate any Benefit Plan or other benefit or compensation plan, program, agreement, policy, contract or arrangement at any time assumed, established, sponsored or maintained by any of them.

Effective as of a mutually agreed-upon date or dates following the expiration of the Transition Services Agreement (but in no event later than September 30, 2020), Seller Parent shall cause the Pension Plan (and all assets thereof) to be transferred and assumed (including the Assumed Pension Liabilities) by Purchaser or an Affiliate of Purchaser; and Purchaser or an Affiliate of Purchaser shall assume the Pension Plan and all Assumed Pension Liabilities thereunder, taking into account all post-Closing payments to retirees and beneficiaries of retirees.

5.17 Preservation of Books and Records; Access and Assistance.

(a)For a period of five (5) years after the Closing Date, Purchaser shall pre-serve and retain all books and records (including any documents relating to any governmental or non-governmental claims, Proceedings or investigations with respect to Seller Parent or its Affiliates) relating to the conduct of the Business or the Acquired Companies prior to the Closing Date. Notwithstanding the foregoing, during such five (5) year period, Purchaser may dispose of any such books and records that are offered in writing to, but not accepted by, Seller Parent. If at any time after the end of the applicable retention period Purchaser intends to dispose of any such books and records, Purchaser shall not do so without first offering such books and records to Seller Parent. If at any time after the end of the applicable retention period, Purchaser intends to dispose of any such books and records, Purchaser shall not do so without first offering such books and records to Seller Parent.

(b)In the event and for so long as either Party is contesting or defending against any Proceeding, hearing, investigation, claim or demand in connection with (i) any Contemplated Transaction or (ii) any fact, situation, circumstance, status, condition, activity, practice, plan, occurrence, event, incident, action, failure to act or transaction prior to the Closing Date involving any Acquired Company or the Business, the other Party shall (A) fully cooperate with the contesting or defending Party and its counsel in, and assist the contesting or defending Party and its counsel with, the contest or defense, (B) make available such other Party’s personnel (including for purposes of fact finding, consultation, interviews, depositions and, if required, as witnesses) and (C) provide such information, testimony and access to its books and records, in each case as shall be reasonably requested in connection with the contest or defense, all at the sole cost and expense (not including employee compensation and benefits costs) of the contesting or defending Party (unless the contesting or defending Party is entitled to indemnification therefor under Article 9). For the avoidance of doubt, this Section 5.17 shall not apply with respect to disputes between the Parties or their respective Affiliates.

5.18 Misdirected Assets. From and after the Closing Date, to the extent that Purchaser or any of its Subsidiaries is in possession of any assets (including litigation claims) that were primarily used in the business of Seller Parent and its Subsidiaries (other than the Business), Purchaser, upon becoming aware of such fact, shall promptly use its commercially reasonable efforts to cause the Person having possession of such asset to cause the transfer, assignment, conveyance and delivery of such asset to Seller Parent or its designated Affiliate, in each case without the payment of any additional consideration.

(b)each of the representations and warranties set forth in Article 3, excluding the Fundamental Representations, without regard to any materiality, Material Adverse Effect or similar qualifiers contained therein, shall be true and correct as of the date hereof and as of the Closing Date (except that such representations and warranties that are made as of a specific date need only be true and correct as of such date), except where the failure of any such representations and warranties to be true and correct would not reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect;

(d)Seller Parent shall have delivered or caused to be delivered, as applicable, each of the items set forth in Section 2.4(c);

ARTICLE 7

TERMINATION

7.1 Termination. This Agreement may be terminated at any time prior to the Closing only as follows:

(a)by mutual consent of Purchaser, on the one hand, and Seller Parent (on behalf of the Sellers), on the other hand;

(b)by Purchaser providing written notice to Seller Parent if there has been a material misrepresentation or material breach of warranty or material breach of covenant on the part of any Seller in the representations and warranties or covenants set forth in this Agreement such that any such material breach or material misrepresentation would cause the applicable closing condition set forth in Section 6.2(a), Section 6.2(b) or Section 6.2(c) to not be satisfied (so long as Purchaser has provided Seller Parent with written notice of such material breach or material misrepresentation and the breach or misrepresentation has continued without cure for a period of thirty (30) days after the notice of breach or misrepresentation or the earlier occurrence of the Outside Date); provided, however, the right to terminate this Agreement under this Section 7.1(b) shall not be available to Purchaser if Purchaser is then in material breach of this Agreement;

(c)by Seller Parent (on behalf of the Sellers) providing written notice to Purchaser if there has been a material misrepresentation or material breach of warranty or material breach of covenant on the part of Purchaser in the representations and warranties or covenants set forth in this Agreement such that any such material breach or material misrepresentation would cause the applicable closing condition set forth in Section 6.1(a), Section 6.1(b) or Section 6.1(c) to not be satisfied (so long as Seller Parent has provided Purchaser with written notice of such material breach or material misrepresentation and the breach or misrepresentation has continued without cure for a period of thirty (30) days after the notice of breach or misrepresentation or the earlier occurrence of the Outside Date); provided, however, the right to terminate this Agreement under this Section 7.1(c) shall not be available to Seller Parent (on behalf of the Sellers) if Sellers are then in material breach of this Agreement; or

(d)by either Purchaser, on the one hand, or Seller Parent (on behalf of the Sellers), on the other hand, if the Contemplated Transactions have not been consummated by April 9, 2020 (the “Outside Date”); provided, however, that a Party shall not be entitled to terminate this Agreement pursuant to this subsection (d) if that Party’s breach of this Agreement has prevented the consummation of the Contemplated Transactions at or prior to such time.

7.2 Effect of Termination. In the event of termination of this Agreement as provided in Section 7.1 hereof, this Agreement shall forthwith become void and there shall be no liability or obligation hereunder on the part of Sellers or Purchaser hereto (other than pursuant to this Section 7.2 and Article 9 which shall survive any such termination), except for Fraud or intentional or willful breaches of this Agreement prior to the time of such termination. For purposes of clarification, if the Purchaser does not

Exhibit 2.1

consummate the Contemplated Transactions if and when it is required to do so pursuant to Section 2.4(a), such event shall be deemed a willful breach by the Purchaser of this Agreement. If the Contemplated Transactions are terminated as provided in Section 7.1, Purchaser acknowledges and agrees that all documents, copies thereof, and all other materials received from or on behalf of any Seller Affiliates relating to the Contemplated Transactions, whether so obtained before or after the execution hereof, shall continue to be subject to the Confidentiality Agreement, which shall remain in full force and effect notwithstanding the termination of this Agreement.

7.3 Waiver of Right to Terminate. Each Party shall be deemed to have waived their respective rights to terminate this Agreement upon consummation of the Contemplated Transactions.

ARTICLE 8

(b)Subject to this Article 8, from and after the Closing, Purchaser shall save, defend, indemnify and hold harmless Sellers and their Affiliates (excluding the Acquired Companies), and each of their respective officers, directors, employees, Representatives, agents and permitted successors and assigns (collectively, the “Seller Indemnified Parties”), on a dollar for dollar basis, without duplication, from and against any and all Losses incurred by any Seller Indemnified Party (A) that arise out of any breach by Purchaser of its covenants under this Agreement and (B) the Assumed Liabilities.

(c)The amount of any and all Losses indemnifiable pursuant to Sections 8.1(a) and 8.1(b) shall be increased to take into account any additional Tax cost incurred by the Indemnified Parties arising from the receipt of the indemnification payment and decreased to take into account any Tax

Exhibit 2.1

benefits actually realized (in the case of any Tax benefits, realized in the taxable period in which the Loss occurs) or recovered by the Indemnified Parties with respect to such Losses.

8.2 Indemnification Procedures.

(a)In connection with any indemnification provided for under this Agreement as a result of a loss or a claim or demand made by any Person against any Indemnified Party (a “Third Party Claim”), such Indemnified Party shall deliver written notice thereof to the Indemnifying Party promptly after receipt by such Indemnified Party of written notice of the Third Party Claim, and in any event within thirty (30) days after receipt of such notice. Indemnified Party’s written notice shall include any written demand, complaint, petition, summons or similar document received and will describe in reasonable detail the facts giving rise to any claim for indemnification hereunder to the extent known, the amount or method of computation of the amount of such claim (if known) and such other information with respect thereto as the Indemnifying Party may reasonably request. The failure to provide such notice, however, shall not release the Indemnifying Party from any of its obligation under this Article 8 except and only to the extent, if any, that the Indemnifying Party is actually prejudiced by such failure.

(b)The Indemnifying Party shall have thirty (30) days from the date of receipt of notice of a Third Party Claim to notify the Indemnified Party that the Indemnifying Party desires to assume the defense or prosecution of the Third Party Claim and any litigation resulting therefrom with counsel of its choice (that is reasonably acceptable to the Indemnified Party) and at its own expense; provided, that the Indemnifying Party shall not have the right to assume the defense or prosecution of any such Third Party Claim that (x) seeks an injunction or other equitable relief against any Indemnified Party or (y) relates to or arises in connection with any matter involving (or potentially involving) criminal or quasi-criminal conduct. If the Indemnifying Party assumes the defense of such claim in accordance herewith, the Indemnified Party may retain separate co-counsel at the Indemnified Party’s sole cost and expense and participate, but not control, the defense of such Third Party Claim. The Indemnified Party shall reasonably cooperate in the defense of any Third Party Claim and shall provide reasonable access, during normal business hours and upon reasonable prior notice, to such personnel, technical support and information as may be reasonably requested by the Indemnifying Party in connection with such defense. The Indemnifying Party shall not consent to the entry of any judgment or enter into any settlement with respect to such Third Party Claim without the prior written consent of the Indemnified Party (such consent not to be unreasonably withheld, conditioned or delayed) unless the judgment or settlement provides solely for the payment of money by the Indemnifying Party, the Indemnifying Party makes such payment in full, and the settlement does not include an admission of liability or wrongdoing on the part of the Indemnified Party.

(c)If the Indemnifying Party does not assume the defense of such Third Party Claim within thirty (30) days of receipt of the notice of the Third Party Claim, elect in writing not to defend any Third Party Claim for which it had previously assumed the defense, fails to diligently defend any Third Party Claim for which it had previously assumed the defense or is not entitled to assume the defense of such Third Party Claim pursuant to Section 8.2(b), the Indemnified Party will be entitled to assume such defense, with the reasonable costs and expenses of such defense to be included in the amount of Losses subject to indemnification by the Indemnifying Party, upon delivery of notice to such effect to the Indemnifying Party; provided, however, that (i) the Indemnifying Party shall have the right to participate in the defense of the Third Party Claim at its sole cost and expense and (ii) if the Indemnifying Party has acknowledged in writing its indemnification obligations to the Indemnified Party with respect to such Third Party Claim, the Indemnifying Party shall not be obligated to indemnify the Indemnified Party hereunder for any settlement entered into or any judgment consented to without the Indemnifying Party’s prior written consent (such consent not to be unreasonably withheld, conditioned, or delayed).

Exhibit 2.1

(d)If any Indemnified Party should have a claim against the Indemnifying Party hereunder that does not involve a Third Party Claim being asserted against or sought to be collected from such Indemnified Party, the Indemnified Party shall deliver written notice of such claim promptly to the Indemnifying Party, and in any event within thirty (30) days of Indemnified Party becoming aware of such claim, describing in reasonable detail the facts giving rise to any claim for indemnification hereunder, the amount or method of computation of the amount of such claim (if known) and such other information with respect thereto as the Indemnifying Party may reasonably request. The failure to provide such notice, however, shall not release the Indemnifying Party from any of its obligations under this Article 8, except and only to the extent, if any, that the Indemnifying Party is actually prejudiced by such failure. The Indemnified Party shall reasonably cooperate and assist the Indemnifying Party in determining the validity of any claim for indemnity by the Indemnified Party and in otherwise resolving such matters.

8.3 Tax Proceedings. Tax Proceedings shall be governed by Section 5.12(j) and not by Section 8.2.

8.4 Duty to Mitigate. The Indemnified Party shall use commercially reasonable efforts to mitigate, to the fullest extent reasonably practicable, the amount of any Losses for which it is entitled to seek indemnification hereunder, and the Indemnifying Party shall not be required to make any payment to the Indemnified Party for that portion of any such Losses that is caused by the Indemnified Party’s failure to comply with its mitigation obligations hereunder.

ARTICLE 9

MISCELLANEOUS

9.3 Assignment. This Agreement and all of the provisions hereof shall be binding upon and inure to the benefit of each of the Parties and their respective successors and permitted assigns. Neither this Agreement nor any rights, benefits or obligations set forth herein may be assigned by any of the Parties without the prior written consent of Purchaser and Seller Parent, except that Purchaser may assign any or all of its rights and obligations under this Agreement to any of its Affiliates without the prior written consent of Seller Parent; provided, that no such assignment shall release Purchaser from any liability or obligation under this Agreement. Any attempted assignment in violation of this Section 9.3 shall be void.

9.4 Severability. Whenever possible, each provision of this Agreement will be interpreted in such manner as to be effective and valid under Applicable Law, but if any provision of this Agreement is held to be prohibited by or invalid under Applicable Law, such provision will be ineffective only to the extent of such prohibition or invalidity, without invalidating the remainder of such provision or the remaining provisions of this Agreement so long as the economic or legal substance of the Contemplated Transactions is not affected in any manner materially adverse to any Party; provided, that the economic and legal substance of the transactions contemplated hereby shall be deemed to be affected in a manner materially adverse to the Parties if Section 9.15 is invalid, illegal or unenforceable.

Exhibit 2.1

9.5 No Strict Construction. The language used in this Agreement shall be deemed to be the language chosen by the Parties to express their mutual intent, and no rule of strict construction will be applied against any Person. The use of the word “including” in this Agreement or in any of the Transaction Documents shall be by way of example rather than by limitation.

9.6 Captions. The captions used in this Agreement are for convenience of reference only and do not constitute a part of this Agreement and shall not be deemed to limit, characterize or in any way affect any provision of this Agreement, and all provisions of this Agreement shall be enforced and construed as if no caption had been used in this Agreement.

9.7 No Third-Party Beneficiaries. Except as otherwise expressly set forth in this Agreement, nothing herein expressed or implied is intended or shall be construed to confer upon or give to any Person, other than the Parties and their respective permitted successors and assigns, any rights or remedies under or by reason of this Agreement.

9.8 Interpretation. The words “hereof” “herein” and “herewith” and words of similar import will, unless otherwise stated, be construed to refer to this Agreement as a whole and not to any particular provision of this Agreement, and Article, Section, Exhibits and Schedule references are to the Articles, Sections, Exhibits and Schedules of this Agreement unless otherwise specified. Whenever the words “include,” “includes” “including” or similar expressions are used in this Agreement, they will be understood to be followed by the words “without limitation.” The words describing the singular number will include the plural and vice versa, and words denoting any gender will include all genders and words denoting natural persons will include corporations, limited liability companies and partnerships and vice versa. The phrase “made available” in this Agreement will mean that the information referred to has been posted in the electronic data room maintained on behalf of the Sellers by Xxxxxxx Corporation at least one (1) Business Day prior to the Closing Date. The descriptive headings of the several Articles and Sections of this Agreement, the Exhibits, Schedules and Table of Contents to this Agreement and the Disclosure Schedules are inserted for convenience only, do not constitute part of this Agreement and shall not affect in any way the meaning or interpretation of this Agreement. The Parties have participated jointly in the negotiation and drafting of this Agreement. In the event of an ambiguity or question of intent or interpretation arises, this Agreement will be construed as if drafted jointly by the Parties and no presumption or burden of proof will arise favoring or disfavoring any Party by virtue of the authorship of any provisions of this Agreement. All references to “$” or “dollars” are to U.S. dollars, and all amounts to be calculated or paid under this Agreement will be in U.S. dollars. When calculating the period of time before which, within which or following which any act is to be done or step taken pursuant to this Agreement, the date that is the reference date in calculating such period shall be excluded and, if the last day of such period is not a Business Day, the period shall end on the next succeeding Business Day.

9.9 Governing Law and Jurisdiction. This Agreement shall be governed by and construed in accordance with the domestic laws of the State of Delaware, without giving effect to any choice of law or conflict of law provision or rule (whether of the State of Delaware or any other jurisdiction) that would cause the application of the laws of any jurisdiction other than the State of Delaware. Each of the Parties hereby irrevocably submits to the exclusive jurisdiction of any state or federal court sitting in Wilmington, Delaware over any suit, action, claim, cross-claim, third-party claim or other proceeding, whether in contract or in tort or otherwise, brought by any Party arising out of or relating to the Contemplated Transactions. In the event of any litigation regarding or arising from this Agreement, the prevailing Party shall be entitled to recover its reasonable expenses, attorneys’ fees and costs incurred therein or in enforcement or collection of any judgment or award rendered therein.

Exhibit 2.1

9.10 Waiver of Jury Trial. EACH PARTY HERETO ACKNOWLEDGES AND AGREES THAT ANY CONTROVERSY WHICH MAY ARISE UNDER THIS AGREEMENT IS LIKELY TO INVOLVE COMPLICATED AND DIFFICULT ISSUES, AND THEREFORE IT HEREBY IRREVOCABLY AND UNCONDITIONALLY WAIVES ANY RIGHT IT MAY HAVE TO A TRIAL BY JURY IN RESPECT OF ANY LITIGATION DIRECTLY OR INDIRECTLY ARISING OUT OF OR RELATING TO THIS AGREEMENT AND ANY OF THE TRANSACTION DOCUMENTS OR CONTEMPLATED TRANSACTIONS.

9.11 No Survival. Except in the case of Fraud (in which case the applicable representations and warranties shall survive the Closing indefinitely), the Parties acknowledge and agree that the representations and warranties of the Parties contained in this Agreement shall terminate and expire as of, and shall not survive beyond, the Closing for all purposes, including any right to damages under any theory or cause of action, and there shall be no liability in respect thereof, including liability for any inaccuracy, misrepresentation or breach of any such representations or warranties on the part of any Party, its Affiliates or any of its or their respective partners, members, officers, directors, employees, agents or representatives.

9.12 Exclusive Remedy. Except for claims for specific performance or other injunctive relief pursuant to Section 9.13 or in the case of Fraud, the Parties acknowledge and agree that the sole and exclusive remedy of Purchaser with respect to any claim arising under or as a result of any breach of a representation or warranty under this Agreement shall be under the R&W Insurance Policy. For the avoidance of doubt, nothing in this Section 9.12 shall affect or otherwise interfere with Purchaser’s rights under the R&W Insurance Policy, and the insurer under the R&W Insurance Policy shall have no right of subrogation against Sellers except the right to proceed against a Seller for monetary damages caused by the Fraud of such Seller (which shall not be imputed to any other Seller) in its capacity as such for the duration of the R&W Insurance Policy.

9.13 Specific Performance. The Parties agree that irreparable damage would occur in the event that any of the provisions of this Agreement were not performed by Purchaser or Sellers, as applicable, in accordance with their specific terms or were otherwise breached by Purchaser or Sellers, as applicable. It is accordingly agreed that the Parties shall be entitled to seek an injunction or injunctions, without any requirement to post or provide any bond or other security in connection therewith, to prevent breaches of this Agreement by any of Purchaser or Sellers, as applicable, and to compel specific performance of the terms and provisions hereof by Purchaser and Sellers, as applicable, by any court having jurisdiction, this being in addition to any other remedy to which the Parties are entitled at law or in equity.

9.14 Attorney-Client Privilege and Conflict Waiver. Squire Xxxxxx Xxxxx (US) LLP has represented the Sellers and the Acquired Companies. All of the Parties recognize the commonality of interest that exists and will continue to exist until Closing, and the Parties agree that such commonality of interest should continue to be recognized after the Closing. Specifically, the Parties agree that (a) Purchaser shall not, and shall cause the Acquired Companies not to, seek to have Squire Xxxxxx Xxxxx (US) LLP disqualified from representing Sellers and their respective Affiliates in connection with any dispute that may arise between any Sellers or their respective Affiliates and Purchaser or the Acquired Companies in connection with this Agreement or the Contemplated Transactions and (b) in connection with any dispute that may arise between any Sellers or their respective Affiliates, on the one hand, and Purchaser or the Acquired Companies, on the other hand, any Sellers or their respective Affiliates involved in such dispute (and not Purchaser or the Acquired Companies) shall have the exclusive right to decide whether or not to waive the attorney client privilege that may apply to any communications between the Acquired Companies and Squire Xxxxxx Xxxxx (US) LLP that occurred before the Closing.

Exhibit 2.1

9.15 Non-Recourse.

(a)This Agreement may only be enforced against the Parties and the Affiliate Guarantors (subject to the terms, conditions and other limitations set forth herein). Subject to the limitations contained herein, (i) all claims or causes of action that may be based upon, arise out of or relate to this Agreement may be made only against the Parties and the Affiliate Guarantors and (ii) except for any express obligations hereunder or under another Transaction Document, no Seller Related Party or Purchaser Related Party shall have any liability or obligation with respect to this Agreement or with respect any claim or cause of action that may arise out of or relate to this Agreement.

(b)Notwithstanding anything that may be expressed or implied in this Agreement, each of the Parties hereto agree, on behalf of such Party and its Affiliates, that this Agreement may only be enforced against, and any claim or cause of action based upon, arising out of, or related to this Agreement may only be brought against, the Parties hereto and the Affiliate Guarantors and then only with respect to the specific obligations set forth herein or in the Affiliate Guarantee (subject to the limitations contained therein), respectively, with respect to any such Party or the Affiliate Guarantors. Except to the extent any Seller Related Party is a named party to this Agreement or another Transaction Document (and then only to the extent of the specific obligations undertaken by such named party in this Agreement or the applicable Transaction Document, and not otherwise), no Seller Related Party shall have any liability to Purchaser or any of its Affiliates relating to or arising out of this Agreement or in respect of any other document or theory of law or equity or in respect of any oral representations made or alleged to be made in connection herewith, whether at law or equity, in contract, in tort or otherwise. Except to the extent any Purchaser Related Party is a named party to this Agreement or another Transaction Document (and then only to the extent of the specific obligations undertaken by such named party in this Agreement or the applicable Transaction Document, and not otherwise), no Purchaser Related Party shall have any liability to Parent, any Seller or any of their respective Affiliates relating to or arising out of this Agreement or in respect of any other document or theory of law or equity or in respect of any oral representations made or alleged to be made in connection herewith, whether at law or equity, in contract, in tort or otherwise.

9.16 Entire Agreement. This Agreement and the other Transaction Documents contain the complete agreement among the Parties and supersede any prior understandings, agreements or representations by or between the Parties, written or oral, which may have related to the subject matter hereof or the Contemplated Transactions in any way.

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