EXECUTION VERSION

CHARAH SOLUTIONS, INC.

INVESTOR RIGHTS AGREEMENT

THIS INVESTOR RIGHTS AGREEMENT (this “Agreement”) dated as of August 6, 2021 is entered into among Charah Solutions, Inc., a Delaware corporation (the “Company”), ▇. ▇▇▇▇▇ Financial, Inc., a Delaware corporation (“▇. ▇▇▇▇▇”) and ▇. ▇▇▇▇▇ Securities, Inc. (“▇. ▇▇▇▇▇ Securities”). The Company, ▇. ▇▇▇▇▇ and ▇. ▇▇▇▇▇ Securities are referred to collectively herein as the “Parties” and, individually, as a “Party.”

RECITALS

WHEREAS, subject to the terms of this Agreement, the Company has agreed, among other things, to expand the size of its Board of Directors (the “Board”) by one member in connection with the consummation of the Transactions (as defined herein) and to nominate and appoint one individual selected by ▇. ▇▇▇▇▇ as a director to fill the vacancy created thereby, subject to certain conditions contained therein (the “Director Appointment Right”), and to provide ▇. ▇▇▇▇▇ with the right to designate and appoint one observer to the Board as provided herein subject to certain conditions contained therein (the “Board Observer Right”).

WHEREAS, ▇. ▇▇▇▇▇ Securities will purchase from the Company, 2,888,889 shares of common stock, $0.01 par value per share (the “Common Stock”) on or around the date hereof, pursuant to that certain Stock Purchase Agreement dated as of August 6, 2021 (the “Stock Purchase Agreement”). The shares of Common Stock issued to ▇. ▇▇▇▇▇ Securities pursuant to the Stock Purchase Agreement shall be referred to in this Agreement as the “Shares.”

NOW, THEREFORE, for good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the Parties agree as follows:

1. Director Appointment Right. For so long as ▇. ▇▇▇▇▇ and its Affiliates beneficially own at least four percent (4%) of the outstanding shares of the Company’s Common Stock, ▇. ▇▇▇▇▇ shall have the right, but not the obligation, to nominate one (1) member to the Board (the “▇. ▇▇▇▇▇ Nominee”), who shall initially be ▇▇▇▇▇▇▇ ▇. ▇▇▇▇▇ (the “Initial ▇. ▇▇▇▇▇ Nominee”), and the Company shall include, and shall use its commercially reasonable efforts to cause the Board, whether acting through a committee of the Board or otherwise, to include, in the slate of nominees recommended to stockholders of the Company (the “Stockholders”) for election as a Class I Director at any annual or special meeting of the Stockholders (or, if permitted, by any action by written consent of the Stockholders) at or by which directors of the Company are to be elected, the ▇. ▇▇▇▇▇ Nominee. The Board has taken action such that the Initial ▇. ▇▇▇▇▇ Nominee shall be appointed to the Board as a Class I Director concurrently with or prior to the consummation of the Transaction (as defined in the Stock Purchase Agreement) (the “Closing”). The ▇. ▇▇▇▇▇ Nominee shall, in the reasonable judgment of the Board, have the requisite skill and experience to serve as a director of a publicly traded company, not be prohibited or disqualified from serving as a director of the Company pursuant to any rule or regulation of the SEC, the New York Stock Exchange (or, if different, the listing exchange on which the Common Stock is traded) or by applicable law and otherwise be reasonably acceptable to the Company. For the avoidance

1

of doubt, the Company acknowledges and agrees that the Initial ▇. ▇▇▇▇▇ Nominee meets all of the aforementioned Board qualifications. The ▇. ▇▇▇▇▇ Nominee shall be subject to the approval of the Board and, as applicable, the Nominating and Corporate Governance Committee (with such approval not to be unreasonably withheld). As used herein, the term “Affiliates” shall mean with respect to any specified person, any other person who, directly or indirectly, controls, is controlled by, or is under common control with such person, including, without limitation, any general partner, managing member, officer, director or trustee of such person, or any registered investment company now or hereafter existing that is controlled by one or more general partners, managing members or investment advisers of, or shares the same management company or investment adviser with, such person.

2. Board Observer Right.

(a) For so long as ▇. ▇▇▇▇▇ and its Affiliates beneficially own at least three percent (3%) of the outstanding shares of Common Stock (based on the number of shares of Common Stock outstanding immediately following the Closing and without regard to any equity issuances (other than equity issuances under the Company’s equity plans) occurring after the Closing), but have no ▇. ▇▇▇▇▇ Nominee then serving on the Board, ▇. ▇▇▇▇▇ shall have the right, but not the obligation, subject to the terms and conditions of this Agreement, to designate and appoint one representative (the “Observer”) to attend all meetings (including telephonic or videoconference meetings of the Board) of the Board (not inclusive of any committees thereof), in a non-voting, observer capacity; provided, however, that such Observer shall agree to hold in confidence all information so provided. The Observer shall not be entitled to be present during executive sessions comprised solely of independent directors of the Board. The Observer shall be subject to the approval of the Board (with such approval not to be unreasonably withheld). Except as otherwise set forth herein, the Observer may participate fully in discussions of all matters brought to the Board for consideration and provide input and advice with respect thereto, but in no event shall the Observer (i) be deemed to be a member of the Board; (ii) without limitation of the obligations expressly set forth in this Agreement, have or be deemed to have, or otherwise be subject to, any duties (fiduciary or otherwise) to the Company or its stockholders; or (iii) have the right to propose or offer any motions or resolutions to the Board or to vote upon any motions or resolutions duly brought before the Board. The Observer shall not be entitled to any cash retainer or equity awards from the Company during the course of his or her appointment to the Board. The presence of the Observer shall not be required or counted for purposes of establishing a quorum at any meeting of the Board.

(b) The Company shall provide to the Observer copies of all notices, minutes, consents and other materials that it provides to all Board members (collectively, “Board Materials”), including any draft versions, proposed written consents, and exhibits and annexes to any such materials, at the same time and in the same manner as such information is delivered to the Board members, provided, however, that such Observer shall agree to hold in confidence all information or materials so provided.

2

(c) Notwithstanding anything herein to the contrary, the Company may exclude the Observer from access to any Board Materials or any Board meeting (or portion thereof) if the Board determines, acting in good faith, that (i) such exclusion is necessary to preserve the attorney-client or work product privilege between the Company (and/or its Affiliates and/or its subsidiaries) and its counsel (provided, however, that any such exclusion shall only apply to such portion of such material or meeting which would be required to preserve such privilege); (ii) such exclusion is necessary to comply with applicable laws, regulations, or any agreement to which the Company (and/or its Affiliates and/or its subsidiaries) is a party or is otherwise bound; or (iii) such Board Materials or discussion relates to the relationship, contractual or otherwise, between the Company (and/or its Affiliates and/or its subsidiaries), on one hand, and ▇. ▇▇▇▇▇ and/or the Observer, on the other hand, or their respective Affiliates (a “Conflict of Interest”). Any Observer shall be required to enter into a confidentiality agreement with the Company prior to the exercise of the rights contained in this Section 2.

(d) The Parties agree that neither the Company nor its Affiliates nor any member of the Board or Committee shall be entitled to rely on any statements or views expressed by the Observer in any Board meeting. The Parties further agree that all information is provided to the Observer “AS IS” and the Company does not make, and expressly disclaims, any representation or warranty as to the accuracy or completeness thereof. Without limiting the foregoing, the Company shall have no liability to the Observer, ▇. ▇▇▇▇▇ Securities or their respective Affiliates or representatives resulting from any use or reliance on any information.

3. Registration Rights.

(a) The Company, upon written demand (a “Demand Notice”) of ▇. ▇▇▇▇▇ Securities or any Affiliate holding the Shares (each a “Registered Holder”), agrees to register, on one occasion, all or any portion of the Shares. On such occasion, the Company will file a registration statement with the SEC covering the resale of the Shares within thirty (30) days after receipt of a Demand Notice and will use its commercially reasonable efforts to have the registration statement declared effective promptly thereafter, subject to compliance with review by the Securities and Exchange Commission. The demand for registration may be made at any time following the issuance of any Shares by the Company through the third (3^rd) anniversary of such issuance. Notwithstanding the foregoing obligations, if the Company furnishes to the Registered Holder requesting a registration pursuant to this Section 3(a) a certificate signed by the Company’s chief executive officer stating that in the good faith judgment of the Board of Directors it would be materially detrimental to the Company and its stockholders for such registration statement to either become effective or remain effective for as long as such registration statement otherwise would be required to remain effective, because such action would (i) materially interfere with a significant acquisition, corporate reorganization, or other similar transaction involving the Company; (ii) require premature disclosure of material information that the Company has a bona fide business purpose for preserving as confidential; or (iii) render the Company unable to comply with requirements under the Securities Act of 1933 (the “Securities Act”) or the Securities Exchange Act of 1934 (the “Exchange Act”), then the Company shall have the right to defer taking action with respect to such filing, and any time periods with respect to filing or effectiveness thereof shall be tolled correspondingly, for a period of not more than one hundred twenty (120) days.

3

(b) The Company shall bear all fees and expenses attendant to the registration of the Shares pursuant to Section 3(a), but the Registered Holder shall pay any and all underwriting commissions and the expenses of any legal counsel selected by the Registered Holder to represent them in connection with the sale of the Shares. The Company agrees to use its commercially reasonable efforts to cause the filing required by Section 3(a) to become effective in accordance with the requirements of Section 3(a) and to qualify or register the Shares in such States as are reasonably requested by the Registered Holder; provided, however, that in no event shall the Company be required to register the Shares in a State in which such registration would cause: (i) the Company to be obligated to register or license to do business in such State or submit to general service of process in such State, or (ii) the principal shareholders of the Company to be obligated to escrow their shares of capital stock of the Company. The Company shall use its commercially reasonable efforts to cause any registration statement filed pursuant to the demand right granted under Section 3(a) to remain effective for a period of at least twelve (12) consecutive months after the date that the Registered Holder is first given the opportunity to sell all of the Shares registered thereunder. The Registered Holder shall only use the prospectuses provided by the Company to sell the shares covered by such registration statement, and will immediately cease to use any prospectus furnished by the Company if the Company advises the Registered Holder that such prospectus may no longer be used due to a material misstatement or omission. For the avoidance of doubt, the Registered Holder shall be entitled to a demand registration under this Section 3 on only one (1) occasion.

(c) In addition to the demand right of registration described in 3(a) hereof, the Registered Holder shall have the right, for a period of three (3) years following the first date upon which the Company issues any Shares, to include the Shares as part of any other registration of securities filed by the Company (other than in connection with a transaction contemplated by Rule 145 promulgated under the Securities Act of 1933, as amended or pursuant to Form S-8 or any equivalent form); provided, however, that if, (i) the managing underwriter(s) thereof shall, in its reasonable discretion, impose a limitation on the number of shares of Common Stock which may be included in the registration statement because, in such underwriter(s)’ judgment, marketing or other factors dictate such limitation is necessary to facilitate public distribution, or (ii) the Company determines in its reasonable discretion to impose a limitation on the number of shares of Common Stock which may be included in the registration statement, or to exclude completely, because, in the Company’s reasonable judgment, inclusion of such shares would violate its existing obligations under that Registration Rights Agreement, dated June 18, 2018, by and between the Company and the initial holders thereto (the “Registration Rights Agreement”), then the Company shall be obligated to include in such registration statement only such limited portion of the Shares with respect to which the Registered Holder requested inclusion hereunder as the underwriter or the Company, as applicable, shall reasonably permit. The Parties hereto agree that this Agreement shall not be construed to violate or subordinate the rights granted to the initial holders under the Registration Rights Agreement.

(d) The Company shall bear all fees and expenses attendant to registering the Shares pursuant to Section 3(c) hereof, but the Registered Holder shall pay any and all underwriting commissions and the expenses of any legal counsel selected by the Registered Holder to represent them in connection with the sale of the Shares. In the event of such a proposed registration, the Company shall furnish the Registered Holder with not less than eight (8) days’ written notice prior to the proposed date of filing of such registration statement. Such notice to the Registered Holder shall continue to be given for each registration statement filed by the Company until such time as all of the Shares have been sold by the Registered Holder. The Registered Holder shall exercise the “piggy-back” rights provided for herein by giving written notice, within five (5) days of the receipt of the Company’s notice of its intention to file a registration statement. There shall be no limit on the number of times the Registered Holder may request registration under this Section 3(d).

4. Notices. All notices and other communications given or made pursuant to this Agreement shall be in writing and shall be deemed effectively given upon the earlier of actual receipt, or (a) personal delivery to the party to be notified, (b) when sent, if sent by electronic mail during normal business hours of the recipient, and if not sent during normal business hours, then on the recipient’s next business day, (c) five (5) days after having been sent by registered or certified mail, return receipt requested, postage prepaid, or (d) one (1) business day after deposit with a nationally recognized overnight courier, freight prepaid, specifying next business day delivery, with written verification of receipt. All communications shall be sent to the respective parties at their address as set forth below, or to such e-mail address, or address as subsequently modified by written notice given in accordance with this Section 4.

5. Governing Law; Venue. This Agreement shall be governed by the internal law of the State of Delaware, without regard to conflict of law principles that would result in the application of any law other than the law of the State of Delaware. The Parties (i) hereby irrevocably and unconditionally submit to the jurisdiction of the state courts of Delaware and to the jurisdiction of the United States District Court for the District of Delaware for the purpose of any suit, action or other proceeding arising out of or based upon this Agreement, (ii)) agree not to commence any suit, action or other proceeding arising out of or based upon this Agreement except

5

in the state courts of Delaware or the United States District Court for the District of Delaware, and (iii) hereby waive, and agree not to assert, by way of motion, as a defense, or otherwise, in any such suit, action or proceeding, any claim that it is not subject personally to the jurisdiction of the above-named courts, that its property is exempt or immune from attachment or execution, that the suit, action or proceeding is brought in an inconvenient forum, that the venue of the suit, action or proceeding is improper or that this Agreement or the subject matter hereof may not be enforced in or by such court.

WAIVER OF JURY TRIAL: TO THE FULLEST EXTENT PERMITTED BY APPLICABLE LAW, EACH PARTY HEREBY WAIVES ITS RIGHTS TO A JURY TRIAL OF ANY CLAIM OR CAUSE OF ACTION BASED UPON OR ARISING OUT OF THIS AGREEMENT, OR THE SUBJECT MATTER HEREOF.

(b) Notwithstanding paragraph (a) above, as soon as practicable, but in any event no later than three (3) business days after the occurrence of the Termination Event of which ▇. ▇▇▇▇▇ becomes aware, ▇. ▇▇▇▇▇ shall provide notice to the Company that the Termination Event has occurred and that this Agreement has been terminated.

(c) In the event that the Company becomes aware that the Termination Event has occurred prior to receiving notice from ▇. ▇▇▇▇▇ as required by paragraph (b) above, the Company shall provide notice to ▇. ▇▇▇▇▇ that it believes that the Termination Event has occurred (the “Company Notice”), and upon ▇. ▇▇▇▇▇’▇ written confirmation to the Company (such confirmation not to be unreasonably withheld or delayed, but in any event, shall be provided within three (3) business days of receiving the Company Notice) that the Termination Event has occurred, this Agreement shall be deemed terminated in accordance with paragraph (a) above and, if requested by the Company, the ▇. ▇▇▇▇▇ Nominee shall promptly resign as a member of the Board and any committees thereof.
