        obligations of the Company (assuming the due authorization, execution and delivery thereof by the Purchaser, as applicable), enforceable in accordance with its terms, except as such enforceability may be limited by bankruptcy, insolvency,
        reorganization and other laws of general applicability relating to or affecting creditors’ rights and by general principles of equity.

        or without notice or lapse of time or both, would constitute such a breach of violation of, or default under), any indenture, mortgage, deed of trust, loan agreement, lease or other agreement or instrument to which any Charah Entity is a party or
        by which any of them or any of their respective Properties may be bound, (y) violates or will violate any statute, Law, Permit or regulation or any order, judgment, decree or injunction of any court or Governmental Authority or body having

        Entity, which conflicts, breaches, violations, defaults or Liens, in the case of clauses (x), (y) or (z), would, individually or in the aggregate, reasonably be expected to have a Material Adverse Effect or materially impair
        the ability of the Company to consummate the transactions contemplated by the Transaction Documents.

      Section 3.06      Company SEC Documents. Except as disclosed in the Company SEC
        Documents, since January 1, 2021, the Company’s forms, registration statements, reports, schedules and statements required to be filed by it under the Exchange Act or the Securities Act (all such documents filed prior
        to the Closing Date, collectively the “Company SEC Documents”) have been filed with the Commission on a timely basis. The Company SEC Documents, at the time filed (or in the case of registration statements,
        solely on the dates of effectiveness) (except to the extent corrected by a subsequent Company SEC Document) (a) did not contain any untrue statement of a material fact or omit to state a material fact required to be stated therein or necessary in
        order to make the statements therein, in light of the circumstances under which they were made, not misleading, (b) complied as to form in all material respects with the applicable requirements of the Exchange Act and the Securities Act, as the
        case may be, and (c) complied as to form in all material respects with applicable accounting requirements and with the published rules and regulations of the Commission with respect thereto. The financial statements of the Company and other
        financial information included in the Company SEC Documents were prepared in accordance with GAAP applied on a consistent basis during the periods involved (except as may be indicated in the notes thereto or, in the case of unaudited statements, as
        permitted by Form 10-Q of the Commission), and fairly present (subject in the case of unaudited statements to normal and recurring and year-end audit adjustments) in all material respects the consolidated financial
        position of the Company and its consolidated Subsidiaries as of the dates thereof and the consolidated results of operations and cash flows of the Company and its consolidated Subsidiaries for the periods then ended. The independent auditor of the
        Company as of the date of the most recent audited balance sheet of the Company is an independent registered public accounting firm with respect to the Company and has not resigned or been dismissed as independent registered public accountants of
        the Company as a result of or in connection with any disagreement with the Company on any matter of accounting principles or practices, financial statement disclosure or auditing scope or procedures. Since the date of the most recent balance sheet
        of the Company audited by such auditor, (x) the interactive data in eXtensible Business Reporting Language included or incorporated by reference in the Company SEC Documents fairly presents the information called for in all material respects and
        has been prepared in accordance with the Commission’s rules and guidelines applicable thereto and (y) based on an annual evaluation of disclosure controls and procedures, except as set forth in the Company SEC Documents, the Company is not aware of
        (i) any material weakness in the design or operation of internal controls over financial reporting that are likely to adversely affect its ability to record, process, summarize and report financial data or (ii) any fraud, whether or not material,
        that involves management or other employees who have a significant role in the internal controls over financial reporting of the Company.

       

      Section 3.07        No Material Adverse Effect. Except as expressly set forth
        in or contemplated by the Company SEC Documents, since January 1, 2021, no Material Adverse Effect has occurred.

       

      Section 3.08        No Registration Required. Assuming the accuracy of the representations and warranties of the Purchaser contained in Article IV, the issuance and sale of the Purchased Shares pursuant to this Agreement is exempt from registration requirements of
        the Securities Act.

       

      Section 3.09       Registration Rights Priority. Except as disclosed
        in the Company SEC Documents, the Company has not granted registration rights that (a) are equal or superior in priority to, or otherwise equal to or greater than, in any respect, those contained in the Amended Registration Rights Agreement, (b)
        reduce the aggregate amount of securities that may be registered pursuant to the Amended Registration Rights Agreement or (c) conflict in any material respect with the rights granted to the Purchaser pursuant to the Amended Registration Rights
        Agreement.

       

      Section 3.10        Litigation. Except as set forth in
        the Company SEC Documents, there are no legal or governmental proceedings pending to which any of the Charah Entities is a party or to which any Property or asset of any of the Charah Entities is subject that would reasonably be expected to have,
        individually or in the aggregate, a Material Adverse Effect or which challenges the validity of any of the Transaction Documents or the right of the Company to enter into any of the Transaction Documents or to consummate the transactions
        contemplated hereby and thereby.

       

      Section 3.11       No Default. None of the Charah Entities is in
        breach of, default under or violation in the performance of (and no condition or event exists that, with or without notice or lapse of time or both, would constitute such a breach of, default under or violation in the performance of) any
        obligation, covenant or condition contained in any bond, debenture, note or any other evidence of indebtedness or in any agreement, indenture, lease or other instrument to which it is a party or by which it or any of its Properties may be bound,
        which breach, default or violation would, if continued, reasonably be expected to have a Material Adverse Effect or materially impair the ability of any of the Charah Entities to perform its obligations under the Transaction Documents.

        the Transaction Documents or the Company’s issuance and sale of the Purchased Shares, except (a) as required by the Commission in connection with this Agreement and the transactions contemplated by this Agreement, (b) as may be required under the
        state securities or “Blue Sky” Laws, (c) as may be required by the rules and regulation of the NYSE, (d) the filing of the Certificate of Designations with the Secretary of State of the State of Delaware or (e) where the failure to receive such

        Effect.

       

      Section 3.13       Distribution Restrictions. Except as
        set forth in the Company SEC Documents, no Charah Entity (other than the Company) is currently prohibited or, as a result of the transactions contemplated by this Agreement, will be prohibited, directly or indirectly, from paying any distributions
        to the Company, from making any other distribution on such entity’s equity interests, from repaying to the Company any loans or advances to such entity from the Company or from transferring any of such entity’s Property or assets to the Company or
        any Subsidiary of the Company, except (a) for prohibitions arising under the Company Credit Agreement, (b) such prohibitions mandated by the Laws of each such Subsidiary’s state of formation and the terms of any such Subsidiary’s Organizational
        Documents and (c) where such prohibition would not reasonably be expected to have a Material Adverse Effect.

       

      Section 3.14        Investment Company Status. None of the Charah Entities is, nor after giving effect to the offering and sale of the Purchased Shares and the application of the net proceeds from such sale, will any of the Charah Entities be, an

      Section 3.15        No Labor Disputes. No labor dispute with the employees of any of the Charah Entities exists or, to the knowledge of the Company, is imminent, that would reasonably be expected to have a Material Adverse Effect.

       

      Section 3.16        Certain Fees.
        Other than the fees payable to the Valuation Firm, which fees will be paid by the Company, no fees or commissions are or will be payable by the Company to brokers, finders or investment bankers with respect to the purchase of any of the Purchased
        Shares or the consummation of the transaction contemplated by this Agreement or the other Transaction Documents.

       

      Section 3.17        Insurance. The Company maintains or
        is entitled to the benefits of insurance from reputable insurers covering its Properties, operations, personnel and businesses against such losses and risks as are reasonably adequate to protect it and its businesses in a commercially reasonable
        manner. All such insurance is outstanding and duly in force on the Closing Date, except for such insurance for which the failure to be outstanding and duly in force would not reasonably be expected to have a Material Adverse Effect.

       

      Section 3.18         Books and Records; Sarbanes-Oxley Compliance.

       

      (a)        Except as disclosed in the Company SEC Documents, the Company maintains a system of internal accounting controls
          sufficient to provide reasonable assurance that: (i) transactions are executed in accordance with management’s general or specific authorizations; (ii) transactions are recorded as necessary to permit preparation of financial statements in
          conformity with GAAP and to maintain asset accountability; (iii) access to assets is permitted only in accordance with management’s general or specific authorization; and (iv) the recorded accountability for assets is compared with the existing

        12

        
          


      

      (b)       The Company has established and maintains disclosure controls and procedures (to the extent required by and as
          defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act), which are designed to provide reasonable assurance that material information required to be disclosed by the Company in reports that it files or submits under the Exchange Act is
          recorded, processed, summarized and communicated to the Company’s management, including its principal executive officer and principal financial officer, as appropriate, to allow for timely decisions regarding required disclosure. The Company has
          carried out evaluations of the effectiveness of its disclosure controls and procedures as of the end of the most recently completed fiscal quarter covered by the Company’s periodic reports filed with the Commission, and, except as disclosed in
          the Company SEC Documents, such disclosure controls and procedures are effective in all material respects to perform the functions for which they were established.

          their capacities as such, are in compliance in all material respects with all applicable provisions of the Sarbanes-Oxley Act of 2002 and the rules and regulations promulgated in connection therewith.

       

      Section 3.19         Listing and Maintenance Requirements. The Common Stock is listed on the NYSE, and the Company has not received any notice of delisting. Subject to the requirements of NYSE Rule 312.03(c), the issuance and sale of the Purchased Shares and issuance

        good faith and for which adequate reserves have been established on the financial statements of the Company in accordance with GAAP). None of the Charah Entities has entered into any transaction that, as of the Closing Date, has been identified by
        the Internal Revenue Service in published guidance as a “listed transaction” as defined under Section 1.6011-4(b)(2) of the Treasury Regulations promulgated under the Code.

          necessary to own its Properties and to conduct its business, except where the failure to possess such Permits would not, individually or in the aggregate, have a Material Adverse Effect, and none of the Charah Entities has received any written
          notice of proceedings relating to the revocation or modification of any such Permit, except where such potential revocation or modification would not, individually or in the aggregate, have a Material Adverse Effect.

       

      
        13

        
          


      

      (b)         The Charah Entities have timely applied for or obtained and are in compliance with all such obtained material
          Environmental Permits required for their operations as currently conducted, except as (i) would not reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect or (ii) have been disclosed in Company SEC Documents.
          The Company has not received written notice of any pending action or proceeding and, to the knowledge of the Company, no action or proceeding is threatened, to suspend, revoke, modify or terminate any Environmental Permit held by the Charah
          Entities that would have a Material Adverse Effect. The operations of the Charah Entities are in compliance with all applicable Environmental Laws and, to the knowledge of the Company, no occurrences or conditions currently exist that would
          reasonably be expected to adversely affect the Charah Entities’ continued compliance with such Environmental Laws and any Environmental Permits issued thereunder, except as (A) would not reasonably be expected to have, individually or in the
          aggregate, a Material Adverse Effect or (B) have been disclosed in Company SEC Documents. There are no present claims asserted against any of the Charah Entities under applicable Environmental Laws, including claims relating to the release, spill
          or disposal of any Hazardous Materials resulting from the operations of the Charah Entities, except as such claims (1) would not reasonably be expected to have, individually or in the aggregate, a Material Adverse Effect or (2) have been
          disclosed in Company SEC Documents.

       

      Section 3.22       Required Disclosures and Descriptions. There
        are no legal or governmental proceedings pending or, to the knowledge of the Company, threatened, against any of the Charah Entities, or to which any of the Charah Entities is a party, or to which any of their respective Properties is subject, that

        Entities has good and indefeasible title to all real property and good title to all personal property described in the Company SEC Documents as owned by such Charah Entity, free and clear of all Liens except (a) as are described in the Company SEC
        Documents, (b) as are created, arise under or secure the Company Credit Agreement, or (c) as would not, in the aggregate, reasonably be expected to have a Material Adverse Effect.

      REPRESENTATIONS AND WARRANTIES OF THE PURCHASER

       

      As an inducement to the Company to enter into this Agreement and consummate the transactions contemplated hereby, the Purchaser hereby represents and warrants that each of the following
        representations are true and correct as of the Closing Date (except as to any representations and warranties that specifically relate to an earlier date, in which case such representations and warranties were true and correct as of such earlier
        date):

       

      Section 4.01        Existence. The Purchaser is duly organized and validly existing and in good standing under the Laws of its state of formation, with all necessary power and authority to own Properties and to conduct its business as
        currently conducted.

       

      
        14

        
          


      

      

      Section 4.02     Authorization; Enforceability. The Purchaser has all necessary legal
        power and authority to enter into, deliver and perform its obligations under the Transaction Documents. The execution, delivery and performance of the Transaction Documents by the Purchaser and the consummation by it of the transactions
        contemplated thereby have been duly and validly authorized by all necessary legal action, and no further consent or authorization of the Purchaser is required. Each of the Transaction Documents has been or, with respect to the Transaction Documents
        to be delivered at the Closing, will be, duly executed and delivered by the Purchaser, where applicable, and constitutes, or will constitute, the legal, valid and binding obligations of the Purchaser (assuming the due authorization, execution and
        delivery thereof by the Company, as applicable); provided that, with respect to each such agreement, the enforceability thereof may be limited by applicable bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium or similar
        laws from time to time in effect affecting creditors’ rights and remedies generally and by general principles of equity (regardless of whether such principles are considered in a proceeding in equity or at law).

       

      Section 4.03       No Breach. The execution, delivery and performance of the Transaction Documents by the Purchaser and the consummation by the Purchaser of the transactions contemplated thereby will not (a) conflict with or result in a
        breach or violation of any of the terms or provisions of, or constitute a default under, any agreement to which the Purchaser is a party or by which the Purchaser is bound or to which any of the Property of the Purchaser is subject, (b) conflict
        with or result in any violation of the provisions of the Organizational Documents of the Purchaser, or (c) violate any statute, order, rule or regulation of any court or governmental agency or body having jurisdiction over the Purchaser or the
        Property of the Purchaser, except in the case of clauses (a) and (c), for such conflicts, breaches, violations or defaults would not prevent the consummation of the transactions contemplated by the Transaction Documents.

       

      Section 4.04        Certain Fees.
        No fees or commissions are or will be payable by or on behalf of the Purchaser to brokers, finders or investment bankers with respect to the purchase of any of the Purchased Shares or the consummation of the transaction contemplated by this
        Agreement or the other Transaction Documents.

       

      Section 4.05         Unregistered Securities.

       

      (a)        Investor Status; Sophisticated Purchaser.
          The Purchaser (i) is, as set forth below the Purchaser’s name on the signature page to this Agreement, either: an institutional “accredited investor” as defined in SEC Rule 501(a)(1), (a)(2), (a)(3), or (a)(7), as presently in effect, or a
          “qualified institutional buyer” as defined in Rule 144A, and, except as otherwise disclosed to the Company to the contrary, in either case, is an “institutional account” as defined in FINRA Rule 4512(c), and (ii) is able to bear the risk of its
          investment in the Purchased Shares and the Underlying Shares. The Purchaser acknowledges that it is able to fend for itself, can bear the economic risk of its investment and has such knowledge and experience in financial and business matters that
          it is capable of evaluating the merits and risks of the purchase of the Purchased Shares and the Underlying Shares. The Purchaser is undertaking its own assessment of the merits of an investment in the Purchased Shares. The Purchaser also
          represents that it has not been organized for the purpose of acquiring the Purchased Shares unless all of the security holders in the Purchaser are Persons who otherwise meet the criteria set forth in this Section 4.05(a).

       

      (b)        Information. The Purchaser and its Representatives have received all the
          information they have requested and consider necessary or appropriate for deciding whether to purchase the Purchased Shares and Underlying Shares. The Purchaser and its Representatives have been afforded the opportunity to ask questions and
          received answers from the Company regarding the terms and conditions of the offering of the Purchased Shares and the Underlying Shares, as well as the business, Properties, prospects and financial condition of the Company. Neither such inquiries
          nor any other due diligence investigations conducted at any time by the Purchaser and its Representatives shall modify, amend or affect the Purchaser’s right (i) to rely on the Company’s representations and warranties contained in Article III
          above or (ii) to indemnification or any other remedy based on, or with respect to the accuracy, inaccuracy or breach of, or compliance with, the representations, warranties, covenants and agreements in any Transaction Document. The Purchaser
          understands that its purchase of the Purchased Shares involves a high degree of risk. The Purchaser acknowledges that the Company is not providing any accounting, legal or tax advice to the Purchaser, but the Purchaser has sought such accounting,
          legal and tax advice as it has considered necessary to make an informed investment decision with respect to its acquisition of the Purchased Shares.

       

      
        15

          for any applicable securities filings.

       

      (d)          Legends. The Purchaser understands that, until such time as the
          Purchased Shares have been registered pursuant to the provisions of the Securities Act, or the Purchased Shares are eligible for resale pursuant to Rule 144 promulgated under the Securities Act without any restriction
          as to the number of securities as of a particular date that can then be immediately sold, the Purchased Shares shall bear a restrictive legend as provided in the Certificate of Designations. The Purchaser understands that, until such time as the
          Underlying Shares have been registered pursuant to the provisions of the Securities Act, or the Underlying Shares are eligible for resale pursuant to Rule 144 promulgated under the Securities Act without any
          restriction as to the number of securities as of a particular date that can then be immediately sold, the Underlying Shares shall bear the following restrictive legend:

       

      “THESE SECURITIES HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED. THEY MAY NOT BE SOLD, OFFERED FOR SALE, PLEDGED OR HYPOTHECATED IN THE
        ABSENCE OF A REGISTRATION STATEMENT IN EFFECT WITH RESPECT TO THE SECURITIES UNDER SUCH ACT OR AN OPINION OF COUNSEL SATISFACTORY TO THE COMPANY THAT SUCH REGISTRATION IS NOT REQUIRED OR UNLESS SOLD PURSUANT TO RULE 144 OF SUCH ACT.”

       

      And any legend required by applicable state “blue sky” securities laws, rules and regulations.

       

      (e)       Purchase Representation. The Purchaser is purchasing the Purchased Shares
          entirely for its own account and not with a view to distribution of any part thereof. The Purchaser has been advised and understands that neither the Purchased Shares nor the Underlying Shares have been registered under the Securities Act or
          under the “blue sky” laws of any jurisdiction and may be resold only if registered pursuant to the provisions of the Securities Act (or if eligible, pursuant to the provisions of Rule 144 promulgated under the
          Securities Act or pursuant to another available exemption from the registration requirements of the Securities Act). By executing this Agreement, the Purchaser further represents that the Purchaser does not have any contract, undertaking,
          agreement or arrangement with any Person to sell, transfer or grant participations to such Person or to any third Person, with respect to any of the Purchased Shares or Underlying Shares. The Purchaser has been advised and understands that the
          Company, in issuing the Purchased Shares, is relying upon, among other things, the representations and warranties of the Purchaser contained in this Article IV in concluding that such issuance is a “private offering” and is exempt from
          the registration provisions of the Securities Act.

       

      (f)         Rule 144. The Purchaser understands
          that there is no public trading market for the Purchased Shares, that none is expected to develop and that the Purchased Shares must be held indefinitely unless and until the Underlying Shares are registered under the Securities Act or an
          exemption from registration is available. The Purchaser has been advised of and is aware of the provisions of Rule 144 promulgated under the Securities Act. In this connection, the Purchaser represents that it is
          familiar with Rule 144, as presently in effect, and understands the resale limitations imposed thereby and by the Securities Act.

      ARTICLE V

      COVENANTS

       

      Section 5.01         Cooperation; Further Assurances. Each of the Company and the Purchaser shall use its respective commercially reasonable efforts to obtain all approvals and consents required by or necessary to consummate the transactions
        contemplated by this Agreement or the other Transaction Documents. From time to time after the Closing Date, without further consideration, the Company and the Purchaser shall use their commercially reasonable efforts to take,

        or cause to be taken, all actions necessary or appropriate to consummate the transactions contemplated by this Agreement, including, without limitation, executing and delivering all such documents or instruments, taking all appropriate action and
        doing all other things such Person determines to be necessary, proper or advisable under applicable Laws and regulations or as otherwise reasonably requested by the parties hereto to consummate the transactions contemplated by this Agreement.

       

      Section 5.02      Use of Proceeds. The Company shall use the proceeds of the Funding Obligation directly or indirectly solely for general corporate purposes.

       

      Section 5.03         Tax Matters.

       

      (a)         Tax Treatment. Absent a contrary determination (as defined in Section 1313(a) of the Code), the Purchaser
          and the Company agree not to treat the Preferred Stock (based on their terms as set forth in the Certificate of Designations) as “preferred stock” within the meaning of Section 305 of the Code and Treasury Regulation Section 1.305-5 for United
          States federal (and applicable state) Tax purposes and shall not take any position inconsistent with such treatment.

       

      (b)       Transfer Taxes. The Company shall pay any and all documentary, stamp or similar issue or transfer Tax due
          on (x) the issue of the Preferred Stock and (y) the issue of the Underlying Shares.

       

      Section 5.04        Listing of Shares. Within 30 days
        following the Closing and subject to the rules of the NYSE, the Company will use its commercially reasonable efforts to obtain approval for listing, subject to notice of issuance, of the Underlying Shares on the NYSE.

       

      Section 5.05        BCP and Purchaser Expenses. Promptly following receipt of an invoice therefor containing reasonable supporting detail, the Company shall make payment to BCP and/or the Purchaser for their respective documented out-of-pocket fees and expenses
          incurred in connection with the negotiation and consummation of the transactions contemplated by this Agreement and the other Transaction Documents (the “Transaction Expenses”).

       

      Section 5.06       Board Designation Rights. From and after the Closing, BCP shall have the right, but not the obligation, to nominate that additional number of designees to the Company’s Board of Directors which would entitle BCP to nominate, in the aggregate together with that
          number of directors which BCP is entitled to nominate from time to time pursuant to the Stockholders’ Agreement, that number of designees as BCP would be entitled to designate pursuant to the Stockholders’ Agreement if (x) the shares of Common
          Stock issuable upon conversion or exchange of the Preferred Stock and the Company’s Series A Preferred Stock (the “Conversion Shares”) were
          deemed to be outstanding for all purposes under the Stockholders’ Agreement and (y) BCP was be deemed to Beneficially Own (as defined in the Stockholders’ Agreement) all such Conversion Shares. The Company’s and BCP’s obligations pursuant to
          Section 2.1 of the Stockholders’ Agreement shall apply to the designation rights set forth in this Section 5.06 as if any and all designees that BCP is entitled to designate hereunder were “BCP Directors” within the meaning of the
          Stockholders’ Agreement. The rights set forth in this Section 5.06 shall terminate upon the earlier to occur of (a) such time as BCP does not Beneficially Own (as defined in the Stockholders’ Agreement) any shares of Common Stock or
          Preferred Stock, (b) mutual agreement by BCP and the Company, and (c) the termination of the Stockholders’ Agreement.

          reasonable efforts to (i) obtain all necessary Permits and qualifications, if any, or secure an exemption therefrom, required by any state or country prior to the offer and sale of the Preferred Stock and (ii) cause such authorization, approval,
          Permit or qualification to be effective as of the Closing and as of any conversion of Preferred Stock.

       

      Section 5.08       Exchange Agreement. After the Closing Date
          and until the consummation of the transactions contemplated by the Exchange Agreement, to be entered into by the parties after the date of this Agreement, the Company and the Purchaser shall use their reasonable best efforts to cooperate with
          each other party and take, or cause to be taken, all reasonable actions necessary or appropriate to deliver the Exchange Agreement, in form and substance reasonably satisfactory to the Purchaser and duly executed by each party thereto, and to
          consummate the transactions contemplated by the Exchange Agreement, including, without limitation, executing and delivering all such documents or instruments, taking all appropriate action and doing all other things such Person determines to be
          necessary, proper or advisable under applicable Laws and regulations or as otherwise reasonably requested by the parties thereto to consummate the transactions contemplated by the Exchange Agreement.

      INDEMNIFICATION, COSTS AND EXPENSES

       

      Section 6.01        Survival
            of Provisions. The Company Fundamental Representations and the Purchaser Fundamental Representations shall survive the execution and delivery of this Agreement indefinitely and the other
        representations and warranties contained in this Agreement shall survive for a period of 15 months following the Closing Date, regardless of any investigation made by or on behalf of the Company or the Purchaser. The covenants made in this
        Agreement or any other Transaction Document shall survive the Closing and remain operative and in full force and effect regardless of acceptance of any of the Purchased Shares and payment therefor and repayment, conversion or repurchase thereof.

       

      Section 6.02        Indemnification by the Company. The Company agrees to indemnify the Purchaser and its Representatives (collectively, “Purchaser Related Parties”) from costs, losses, liabilities, damages, or expenses
        of any kind or nature whatsoever, and hold each of them harmless against, any and all actions, suits, proceedings (including any investigations, litigation or inquiries), demands, and causes of action, and, in connection therewith, and promptly
        upon demand, pay or reimburse each of them for all costs, losses, liabilities, damages, or expenses of any kind or nature whatsoever (including the reasonable fees and disbursements of counsel and all other reasonable expenses incurred in
        connection with investigating, defending or preparing to defend any such matter that may be incurred by them or asserted against or involve any of them), whether or not involving a Third-Party Claim (collectively, “Damages”),
        as a result of, arising out of, or in any way related to (a) the failure of any of the representations or warranties made by the Company contained herein to be true and correct in all material respects as of the Closing (except to the extent any
        representation or warranty includes the word “material,” Material Adverse Effect or words of similar import, with respect to which such representation or warranty, or applicable portions thereof, must have been true and correct in all respects) or
        (b) the breach of any covenants of the Company contained herein; provided that, in the case of the immediately preceding clause (a), such claim for indemnification is made prior to the expiration of the survival period of such
        representation or warranty, in which case the indemnification obligations of the Company with respect to such claim shall survive indefinitely; provided, further, that for purposes of determining when an indemnification claim has
        been made, the date upon which a Purchaser Related Party shall have given notice (stating in reasonable detail the basis of the claim for indemnification) to the Company shall constitute the date upon which such claim has been made.

       

      
        18

        
          


      

      Section 6.03        Indemnification by the Purchaser. The Purchaser agrees to indemnify the Company and its Representatives (collectively, “Company Related Parties”) from costs, losses, liabilities, damages, or expenses of
        any kind or nature whatsoever, and hold each of them harmless against, any and all actions, suits, proceedings (including any investigations, litigation or inquiries), demands, and causes of action, and, in connection therewith, and promptly upon
        demand, pay or reimburse each of them for all costs, losses, liabilities, damages, or expenses of any kind or nature whatsoever (including the reasonable fees and disbursements of counsel and all other reasonable expenses incurred in connection
        with investigating, defending or preparing to defend any such matter that may be incurred by them or asserted against or involve any of them), whether or not involving a Third-Party Claim, as a result of, arising out of, or in any way related to
        (a) the failure of any of the representations or warranties made by the Purchaser contained herein to be true and correct in all material respects as of the Closing or (b) the breach of any of the covenants of the Purchaser contained herein; provided
        that, in the case of the immediately preceding clause (a), such claim for indemnification is made prior to the expiration of the survival period of such representation or warranty, in which case the indemnification obligations of the
        Purchaser with respect to such claim shall survive indefinitely; provided, further, that for purposes of determining when an indemnification claim has been made, the date upon which a Company Related Party shall have given notice
        (stating in reasonable detail the basis of the claim for indemnification) to the Purchaser shall constitute the date upon which such claim has been made; provided, further, that the liability of the Purchaser shall not be greater in
        amount than the sum of the Purchaser’s Funding Obligation plus any distributions paid to the Purchaser with respect to the Purchased Shares.

       

      Section 6.04        Indemnification for Certain Fees. The
          Company agrees that it will indemnify and hold harmless the Purchaser from and against any and all claims, demands, or liabilities for broker’s, finder’s, placement, or other similar fees or commissions incurred by the Company or alleged to have
          been incurred by the Company in connection with the sale of the Purchased Shares or the consummation of the transactions contemplated by this Agreement and the other Transaction Documents.

       

      Section 6.05        Indemnification Procedure.

       

      (a)         Promptly after any Company Related Party or Purchaser Related Party (hereinafter, the “Indemnified Party”) has received notice of any indemnifiable claim hereunder, or the commencement of any action, suit or proceeding by a third Person, which the Indemnified Party believes in good faith is an indemnifiable claim
          under this Agreement (each a “Third-Party Claim”), the Indemnified Party shall give the indemnitor hereunder (the “Indemnifying Party”) written notice of such
          Third-Party Claim or the commencement of such action, suit or proceeding, but failure to so notify the Indemnifying Party will not relieve the Indemnifying Party from any liability it may have to such Indemnified Party hereunder except to the
          extent that the Indemnifying Party is materially prejudiced by such failure. Such notice shall state the nature and the basis of such Third-Party Claim to the extent then known. The Indemnifying Party shall have the right to defend and settle, at
          its own expense and by its own counsel who shall be reasonably acceptable to the Indemnified Party, any such matter as long as the Indemnifying Party pursues the same diligently and in good faith. If the Indemnifying Party undertakes to defend or
          settle, it shall promptly notify the Indemnified Party of its intention to do so, and the Indemnified Party shall reasonably cooperate with the Indemnifying Party and its counsel in all commercially reasonable respects in the defense thereof and
          the settlement thereof. Such cooperation shall include, but shall not be limited to, furnishing the Indemnifying Party with any books, records and other information reasonably requested by the Indemnifying Party and in the Indemnified Party’s
          possession or control. Such cooperation of the Indemnified Party shall be at the cost of the Indemnifying Party. After the Indemnifying Party has notified the Indemnified Party of its intention to undertake to defend or settle any such asserted
          liability, and for so long as the Indemnifying Party diligently pursues such defense, the Indemnifying Party shall not be liable for any additional legal expenses incurred by the Indemnified Party in connection with any defense or settlement of
          such asserted liability; provided that the Indemnified Party shall be entitled (i) at its expense, to participate in the defense of such asserted liability and the negotiations of the settlement thereof and (ii) if (A) the Indemnifying
          Party has, within 10 business days of when the Indemnified Party provides written notice of a Third-Party Claim, failed to (1) assume the defense or employ counsel reasonably acceptable to the Indemnified Party and (2) notify the Indemnified
          Party of such assumption within such 10 business day period or (B) the defendants in any such action include both the Indemnified Party and the Indemnifying Party and counsel to the Indemnified Party shall have concluded that there may be
          reasonable defenses available to the Indemnified Party that are different from or in addition to those available to the Indemnifying Party or if the interests of the Indemnified Party reasonably may be deemed to conflict with the interests of the
          Indemnifying Party, then the Indemnified Party shall have the right to select one separate counsel (plus appropriate local counsel) and to assume such legal defense and otherwise to participate in the defense of such action, with the documented
          and out-of-pocket expenses and fees of such separate counsel and other expenses related to such participation to be reimbursed by the Indemnifying Party as incurred. Notwithstanding any other provision of this Agreement, the Indemnifying Party
          shall not settle any indemnified Third-Party Claim without the consent of the Indemnified Party (which consent shall not be unreasonably delayed), unless the settlement thereof is for money damages only and imposes no liability or obligation on,
          includes a complete release from liability of, and does not include any admission of wrongdoing or malfeasance by, the Indemnified Party.

       

      
        19

        
          


      

      (b)          Notwithstanding anything to the contrary herein, each Indemnified Party shall use its commercially reasonable
          efforts to mitigate to the extent required by Law the amount of any costs, losses, liabilities, Damages, or expenses of any kind or nature whatsoever for which it is indemnified pursuant to this Article VI.

       

      Section 6.06         Exclusive Remedy.

       

      (a)          Each party hereto hereby acknowledges and agrees that the rights of each party
          to consummate the transactions contemplated hereby are special, unique and of extraordinary character and that, if any party violates or fails or refuses to perform any covenant or agreement made by it herein, the non-breaching party may be
          without an adequate remedy at law. If any party violates or fails or refuses to perform any covenant or agreement made by such party herein, the non-breaching party, subject to the terms hereof and in addition to any remedy at law for damages or
          other relief, may (at any time prior to the Closing) institute and prosecute an action in any court of competent jurisdiction to enforce specific performance of such covenant or agreement or seek any other equitable relief.

       

      (b)          The sole and exclusive remedy for any and all claims arising under, out of, or related to this Agreement or the
          transactions contemplated hereby, shall be the rights of indemnification set forth in this Article VI only, and no Person will have any other entitlement, remedy or recourse, whether in contract, tort or otherwise, it being agreed that
          all of such other remedies, entitlements and recourse are expressly waived and released by the parties hereto to the fullest extent permitted by Law. Notwithstanding anything in the foregoing to the contrary, nothing in this Agreement shall limit
          or otherwise restrict a fraud claim brought by any party hereto or the right to seek specific performance pursuant to Section 6.06(a).

        Agreement are references to the corresponding Article and Section of, and Schedule to, this Agreement, unless otherwise specified. All Schedules to this Agreement are hereby incorporated and made a part hereof as if
        set forth in full herein and are an integral part of this Agreement. All references to instruments, documents, Contracts and agreements are references to such instruments, documents, Contracts and agreements as the same may be amended, supplemented
        and otherwise modified from time to time, unless otherwise specified. The word “including” shall mean “including but not limited to” and shall not be construed to limit any general statement that it follows to the specific or similar items or
        matters immediately following it. Whenever the Company has an obligation under the Transaction Documents, the expense of complying with that obligation shall be an expense of the Company unless otherwise specified. Any reference in this Agreement
        to “$” shall mean U.S. dollars. Whenever any determination, consent or approval is to be made or given by the Purchaser or the Company, such action shall be in the Purchaser’s or the Company’s sole discretion, as applicable, unless otherwise
        specified in this Agreement. If any provision in the Transaction Documents is held to be illegal, invalid, not binding or unenforceable, (a) such provision shall be fully severable and the Transaction Documents shall be construed and enforced as if
        such illegal, invalid, not binding or unenforceable provision had never comprised a part of the Transaction Documents, and the remaining provisions shall remain in full force and effect, and (b) the parties hereto shall negotiate in good faith to
        modify the Transaction Documents 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. Any words imparting the singular number only shall include the plural and vice versa. The words such as “herein,” “hereinafter,” “hereof” and “hereunder” refer to this Agreement as a whole and not merely to a subdivision in which such

      (a)          Delay. No failure or delay on the part of any party in exercising any
          right, power or remedy hereunder shall operate as a waiver thereof, nor shall any single or partial exercise of any such right, power or remedy preclude any other or further exercise thereof or the exercise of any other right, power or remedy.
          The remedies provided for herein are cumulative and are not exclusive of any remedies that may be available to a party at law or in equity or otherwise.

       

      (b)         Specific Waiver. Except as otherwise provided herein, no amendment,
          waiver, consent, modification or termination of any provision of any Transaction Document shall be effective unless signed by each of the parties thereto affected by such amendment, waiver, consent, modification or termination. Any amendment,
          supplement or modification of or to any provision of any Transaction Document, any waiver of any provision of any Transaction Document and any consent to any departure by the Company from the terms of any provision of any Transaction Document
          shall be effective only in the specific instance and for the specific purpose for which made or given. Except where notice is specifically required by this Agreement, no notice to or demand on the Company in any case shall entitle the Company to
          any other or further notice or demand in similar or other circumstances. Any investigation by or on behalf of any party shall not be deemed to constitute a waiver by the party taking such action of compliance with any representation, warranty,
          covenant or agreement contained herein.

       

      Section 7.03       Binding Effect.
        This Agreement shall be binding upon the Company, the Purchaser and their respective successors and permitted assigns. Except as expressly provided in this Agreement, this Agreement shall not be construed so as to confer any right or benefit upon
        any Person other than the parties to this Agreement and their respective successors and permitted assigns.

      (a)       Notwithstanding the foregoing, this Agreement shall not impact the terms and provisions of the Confidentiality
          Provisions. The Confidentiality Provisions shall continue to be in full force and effect, pursuant to the terms and conditions thereof.

       

      (b)        Other than filings made by the Company with the Commission, neither the Company nor any of its Representatives
          shall disclose the identity of, or any other information concerning, the Purchaser or any of their respective Affiliates until having first provided the Purchaser a reasonable opportunity to review and comment on such disclosure (with such
          comments being incorporated or reflected, to the extent reasonable, in any such disclosure); provided that nothing in this Section 7.04 shall delay any required filing or other disclosure with the Commission, NYSE or any
          Governmental Authority or otherwise hinder the Charah Entities’ or their respective Representatives’ ability to timely comply with all Laws or rules and regulations of the Commission, NYSE or other Governmental Authority.

      Section 7.07        Assignment. This Agreement may not be assigned to any other Person
        without the written consent of the other party hereto; provided that, prior to the Closing, the Purchaser may, without the prior written consent of the Company, assign its rights to purchase the Purchased Shares under this Agreement, in
        whole or in part to an Affiliate of the Purchaser; provided further, however, that no such assignment shall relieve the Purchaser of any of its obligations hereunder.

       

      Section 7.08      Governing Law; Submission to Jurisdiction. This Agreement, and all claims or causes of action (whether in contract or tort or otherwise) that may be based upon, arise out of or relate to this Agreement or the negotiation, execution or performance of
        this Agreement (including any 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), will be construed in accordance with and governed by the Laws of the State
        of Delaware without regard to principles of conflicts of laws which would result in the application of the Law of any other jurisdiction. Any action against any party relating to the foregoing shall be brought exclusively in any federal or state
        court of competent jurisdiction located within the State of Delaware, and the parties hereto hereby irrevocably submit to the jurisdiction of such courts. The parties hereby irrevocably waive, to the fullest extent permitted by applicable Law, any

        Section 6.6        Amendments; Invalidity; Enforceability. This Agreement may not be amended, changed, supplemented, waived or otherwise modified except as may be agreed by each of the Parties in writing. If any provision of this Agreement, or its application to any Party, shall be, or be found by an authority of competent jurisdiction to be, unenforceable or invalid in whole or in part, such provision shall be constructed and applied so as to give effect, to the greatest extent
          possible, to the original intent of the parties to this Agreement. The invalidity or unenforceability of any provision of this Agreement shall in no way affect the validity or enforceability of any other provision
          of this Agreement.

         

        Section 6.7       Governing Law; Jurisdiction; Jury Trial. The Laws of the State of Delaware shall exclusively govern: (i) all disputes, claims, controversies or matters based upon, related to or arising from this Agreement (including any tort or non-contractual claims), or any
          of the transactions contemplated by this Agreement; and (ii) any questions concerning the construction, interpretation, validity and enforceability of this Agreement, and the performance of the obligations imposed by this Agreement, in each case
          without giving effect to any choice‐of‐law or conflict‐of‐law rules or provisions (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 PARTY TO THIS AGREEMENT IRREVOCABLY WAIVES ALL RIGHTS TO TRIAL BY JURY IN ANY ACTION, SUIT OR PROCEEDING BROUGHT TO RESOLVE ANY DISPUTE, CLAIM, CONTROVERSY OR MATTER BETWEEN OR AMONG ANY OF THE PARTIES (WHETHER
          ARISING IN CONTRACT, TORT OR OTHERWISE) ARISING OUT OF, CONNECTED WITH, RELATED OR INCIDENTAL TO THIS AGREEMENT, THE TRANSACTIONS CONTEMPLATED BY THIS AGREEMENT OR THE RELATIONSHIPS ESTABLISHED AMONG SUCH PERSONS BY THIS AGREEMENT. THE PARTIES
          FURTHER WARRANT AND REPRESENT THAT EACH HAS REVIEWED THIS WAIVER WITH ITS LEGAL COUNSEL, AND THAT EACH KNOWINGLY AND VOLUNTARILY WAIVES ITS JURY TRIAL RIGHTS FOLLOWING CONSULTATION WITH LEGAL COUNSEL. Each of the Parties
          agrees that jurisdiction and venue in any suit, action, or proceeding brought by any Party pursuant to this Agreement shall properly and exclusively lie in the Chancery Court of the State of Delaware sitting in
          Wilmington or, solely to the extent the Chancery Court declines jurisdiction in respect of a particular dispute, the Federal Court in Delaware sitting in Wilmington (the “Chosen Courts”). Nothing in this Section 6.7 however, shall affect the
          right of any Party to serve legal process in any other manner permitted by law or at equity. Each Party further agrees and covenants that no proceeding relating to this Agreement or
          the transactions contemplated by this Agreement shall be brought by it except in the Chosen Courts. The Parties irrevocably and unconditionally waive (and agree not to plead or claim) any objection to: (i) the
          laying of venue of any proceeding arising out of or relating to this Agreement or the transactions contemplated by this Agreement in the Chosen Courts; or (ii) that any such proceeding brought in the Chosen Courts has been brought in an
          inconvenient forum. Each Party agrees that a final judgment in any proceeding brought in the Chosen Courts shall be conclusive and may be enforced by suit on the judgment or in any other manner provided by law or at
          equity.

         

        Section 6.8        Entire Agreement. This Agreement and the other Definitive Documents constitute the full and entire understanding and agreement among the Parties with respect to the subject matter of this Agreement. Any other written or oral agreement relating
          to the subject matter of this Agreement existing among the Parties is expressly cancelled.

         

        Section 6.9   Specific
              Performance. Each of the Parties acknowledges and agrees that money damages would not be a sufficient remedy for any breach of any of the agreements, covenants or obligations under this Agreement by any Party. Consequently, each
          non-breaching party to this Agreement would be damaged irreparably by any such breach and shall be entitled to seek specific performance and injunctive or other equitable relief, including attorneys’ fees and costs, as a remedy of any such
          breach. Each Party also agrees to waive any requirement for the securing or posting of a bond in connection with such remedy, in addition to any other remedy to which such non-breaching party may be entitled, at law or in equity. The breaching
          Party shall reimburse each non-breaching party that prevails in obtaining such specific performance or other relief for all costs and expenses incurred in connection with obtaining such specific performance.

         

        Section 6.10          Release;
              Indemnification.

         

        (a)         Effective as of the Closing, for good and valuable considerations, the receipt and sufficiency of which are hereby acknowledged and confirmed,
          each of the Transferor Parties, on behalf of itself and its Affiliates (collectively, the “Releasing Parties”) shall, and hereby do, absolutely, irrevocably and unconditionally release, acquit, waive and
          forever discharge each Transferee Party and each of the Transferee Parties’ Affiliates (collectively, the “Released Parties”) and, in each case, their
          respective assets and property, to the fullest extent permitted by law, from and against (i) any and all claims, judgments, orders, executions, suits, demands, Liens, actions, administrative proceedings, and causes of action  (including any Environmental Liabilities) of every kind and nature whatsoever, direct or indirect, asserted or unasserted, whether absolute or contingent, liquidated or
          unliquidated, matured or unmatured, whether derivative or otherwise, whether existing or arising at law, in equity or otherwise, whether known or unknown,
          whether disputed or undisputed, whether suspected or unsuspected, whether foreseen or unforeseen, whether now or hereafter existing, including, without limitation, any claims, crossclaims, counterclaims and rights of set-off and recoupment (each,
          a “Claim”), that the Releasing Parties would have, at any time prior to, on or after the date of this Agreement, been legally entitled to assert in their own right (whether individually or collectively) or
          by, through, or on behalf of the holder of any claim or ownership interest in such Releasing Party, based upon any event, circumstance, act, transaction, representation, misrepresentation, or omission occurring or existing on or prior to the
          Closing arising out of, relating to or in connection with, in whole or in part: the Gibbons Creek Credit Agreement and the loan documents (the
          Claims described in the foregoing, collectively, “Released Claims”), and (ii) from all damages, liabilities, injuries, contributions, indemnities, compensation, obligations, costs, fees and expenses
          (including attorneys’ fees and expenses) or other obligations  (including any Environmental Liabilities) of every kind and nature whatsoever, direct or indirect, asserted or unasserted, whether absolute or contingent, liquidated or unliquidated,
          matured or unmatured, whether derivative or otherwise, whether existing or arising at law, in equity or otherwise, whether known or unknown, whether disputed or undisputed, whether suspected or unsuspected,
          whether foreseen or unforeseen, whether now or hereafter existing (collectively, “Damages”), arising out of, relating to or in connection with, in whole or in part, such Released Claims.

         

        (b)       EXCEPT AS OTHERWISE PROVIDED HEREIN, THE RELEASING PARTIES, HEREBY EXPRESSLY AGREE THAT THE CLAIMS OR DAMAGES RELEASED HEREBY SHALL INCLUDE, WITHOUT
          LIMITATION, SUCH CLAIMS OR DAMAGES ARISING PRIOR TO THE CLOSING AS A DIRECT OR INDIRECT RESULT OF THE GROSS NEGLIGENCE OR WILFUL MISCONDUCT OF ANY RELEASED PARTY.

        (c)         The release of Released Parties contained herein is a final release, effective as of the Closing, even if there may exist a mistake on the part of
          any Releasing Party as to the extent and nature of the claims, injuries, and damages of the Releasing Parties against the Released Parties. For the avoidance of doubt,
          the Releasing Parties, knowingly grants the release contained in this Section 6.10 notwithstanding that any such Releasing Party may hereafter discover facts in addition to, or different from, those which either such Releasing Party now
          knows or believes to be true, and without regard to the subsequent discovery or existence of such different or additional facts, and such Releasing Party expressly waives any and all rights that such Releasing Party may have under any statute or
          common law principle which would limit the effect of the release to those claims actually known or suspected to exist before the Effective Date. Each of the Parties
          represents and warrants that it has access to adequate information regarding the terms hereof, the scope and effect of the release contained in this Section 6.10, and all other matters encompassed
          by this Agreement to make an informed and knowledgeable decision with regard to entering into the Agreement. Each of the Parties agrees and acknowledges that, except as expressly provided in this Agreement, no other Party, in any capacity, has
          warranted or otherwise made any representations concerning any Released Claim (including any representation or warranty concerning the existence, non-existence, validity, or invalidity of any Released Claim). Notwithstanding the foregoing,
          nothing contained in this Agreement is intended to impair or otherwise derogate from any of the representations, warranties, or covenants expressly set forth in this Agreement.

         

        (d)          The Releasing Parties, agrees that this Agreement, following the Closing, may be pleaded as a full and complete defense to, and may be used as a
          basis for an injunction against, any Proceeding which may be instituted, prosecuted or attempted in breach of this Agreement by it or any other Releasing Party. Notwithstanding anything to the contrary contained herein, each of the Parties agrees
          that if any release contained in this Section 6.10 shall be unenforceable against any Releasing Party, and such Releasing Party institutes or files any cause of action against any Released Party, then the releases contained in this Section

            6.10 shall not be effective in preventing any such Released Party from raising any defenses, objections, set-offs, recoupments, or counterclaims to such cause of action against such Releasing Party, nor prohibit any such Released Party
          from seeking any indemnification or contractual expense reimbursement they are otherwise entitled to from whatever source, in each case solely to the extent to offset any such cause of action.

         

        (e)       Without in any way limiting any of the rights and remedies otherwise available to any Released Party, the Releasing Parties shall indemnify and hold
          harmless each Released Party from and against all Losses, whether or not involving third-party claims, arising out of, relating to or in connection with, in whole or in part: (i) the assertion by or
          on behalf of any Releasing Party of any Claims or Damages purported to be released pursuant to this Agreement or the Definitive Documents, (ii) the assertion by any third party of any claim or demand against
          any Released Party which claim or demand arises directly or indirectly from, or in connection with, any assertion by or on behalf of any Releasing Party against such third party of any Claims or Damages
          purported to be released by any Releasing Party and (iii) any Environmental Liabilities associated with Gibbons Creek Land, Cheswick Land, or any other Person, to the extent assumed or undertaken by Holdco in connection with the Acquired Land or
          for which CERG, Gibbons Creek or Cheswick has provided an indemnity with respect thereto or otherwise become subject, whether existing, occurring, or arising prior to, on, or after the date of this Agreement.

         

        Section 6.11   Tax Treatment. For U.S. federal, and applicable state and local income tax purposes, the Parties intend that the Exchange be treated as the transfer by CERG (or its
            regarded owner for federal income tax purposes, as applicable) of the assets owned by Cheswick and Gibbons Creek to Holdco in full satisfaction of the Gibbons Creek Debt, to the extent permissible under applicable Law.

                CERG will transfer, or will cause Gibbons Creek and/or Cheswick to transfer, as applicable, to the Lender the Acquired Land, which may occur via transfer of title to such Acquired Land to Lender or via
                  transfer of such Acquired Land to an Affiliate of Lender in which CERG (and/or Gibbons Creek or Cheswick, as applicable) owns equity interests to give effect to the Land Proceeds Waterfall (as defined below).

                CERG or its applicable Affiliate shall retain responsibility for (i) the MELT profit share with respect to dispositions of the Acquired Land and (ii) existing remediation obligations with respect to the
                  Acquired Land (collectively, the “Indemnified Obligations”).  CERG shall indemnify the Transferee Parties from any and all Losses arising out of or related to the Indemnified Obligations.

                4.   General
