Perma-Fix Environmental Services, Inc.

Atlanta, GA 30350

Attention: Mark Duff, President and Chief Executive Officer

Dear Mr. Duff:

This letter (the “Agreement”) constitutes the agreement between Craig-Hallum Capital Group LLC (“Craig-Hallum”) and Wellington Shields & Co. LLC (“Wellington” and together with Craig-Hallum, the “Placement Agents”) and Perma-Fix Environmental Services, Inc., a Delaware corporation (the “Company”), that the Placement Agents shall serve as the exclusive placement agents for the Company, on a “best efforts” basis, in connection with the proposed registered direct offering (the “Offering”) of shares (the “Shares”) of the Company’s common stock, par value $0.001 per share (the “Common Stock”). The Shares actually placed by the Placement Agents in connection with the Offering are referred to herein as the “Placement Agent Shares.” The terms of the Offering shall be mutually agreed upon by the Company and the purchasers (each, a “Purchaser” and collectively, the “Purchasers”), and nothing herein grants the Placement Agents the power or authority to bind the Company or any Purchaser, or constitutes an obligation that the Company will issue any Shares or complete the Offering. The Company expressly acknowledges and agrees that the Placement Agents’ obligations hereunder are on a best efforts basis only and that the execution of this Agreement does not constitute a commitment by the Placement Agents to purchase the Shares and does not ensure the successful placement of the Shares or any portion thereof or the success of the Placement Agents with respect to securing any other financing on behalf of the Company. Certain affiliates of the Placement Agents may participate in the Offering by purchasing some of the Placement Agent Shares. The sale of Placement Agent Shares to any Purchaser will be evidenced by a securities purchase agreement (the “Purchase Agreement”) between the Company and such Purchaser, in a form reasonably acceptable to the Company and such Purchaser. Capitalized terms that are not otherwise defined herein have the meanings given to such terms in the Purchase Agreement. Prior to the signing of any Purchase Agreement, officers of the Company will be available to answer inquiries from prospective Purchasers. The Company retains the right, in its sole discretion, to approve or reject any potential investor in the Offering and to approve or disapprove, in its sole discretion, the final terms and conditions of the Offering.

SECTION 1. REPRESENTATIONS AND WARRANTIES OF THE COMPANY.

A. Representations of the Company in the Purchase Agreement. With respect to the Placement Agent Shares, each of the representations and warranties (together with any related disclosure schedules thereto) and covenants made by the Company to the Purchasers in the Purchase Agreement in connection with the Offering is hereby incorporated herein by reference into this Agreement (as though fully restated herein) and is, as of the date of this Agreement and as of the Closing Date, hereby made to, and in favor of, the Placement Agents.

B. FINRA Affiliation. In addition to the foregoing, the Company represents and warrants that there are no affiliations with any FINRA member firm among the Company’s officers or directors, except as set forth in the Purchase Agreement.

C. Placement Agent Warrants. The Placement Agent Warrants (as defined below), when issued hereunder, will be valid and binding obligations of the Company, enforceable against the Company in accordance with their terms, except: (i) as limited by general equitable principles and applicable bankruptcy, insolvency, reorganization, moratorium and other laws of general application affecting enforcement of creditors’ rights generally, (ii) as limited by laws relating to the availability of specific performance, injunctive relief or other equitable remedies and (iii) insofar as indemnification and contribution provisions may be limited by applicable law. The shares of Common Stock underlying the Placement Agent Warrants are duly authorized and, when issued and paid for in accordance with the terms of the Placement Agent Warrants, will be validly issued, fully paid and non-assessable. The Company has reserved from its duly authorized capital stock the maximum number of shares of Common Stock issuable upon exercise of the Placement Agent Warrants. As of the Closing, the Company shall have reserved from its duly authorized capital stock not less than 100% of the maximum number of shares of Common Stock issuable upon exercise of the Placement Agent Warrants (without taking into account any limitations on the exercise of the Placement Agent Warrants set forth therein).

SECTION 2. REPRESENTATIONS OF THE PLACEMENT AGENTS. Each Placement Agent represents and warrants that it (i) is a member in good standing of FINRA, (ii) is registered as a broker/dealer under the Exchange Act, (iii) is licensed as a broker/dealer under the laws of the United States of America, applicable to the offers and sales of the Placement Agent Shares by such Placement Agent, (iv) is and will be a corporate body validly existing under the laws of its place of organization, (v) has full power and authority to enter into and perform its obligations under this Agreement and (vi) has not provided, and will not provide during the pendency of the Offering, to any potential investors, any material nonpublic information relating to the Company other than the information contained in the Transaction Documents. Each Placement Agent will immediately notify the Company in writing of any change in its status with respect to subsections (i) through (vi) above. Each Placement Agent covenants that it will use its reasonable best efforts to conduct the Offering hereunder in compliance with the provisions of this Agreement and the requirements of applicable law.

SECTION 3. COMPENSATION.

A. In consideration of the services to be provided for hereunder, the Company shall pay to the Placement Agents and/or their respective designees a cash fee (the “Cash Fee”) of 6.0% of the aggregate gross proceeds raised from the sale of the Placement Agent Shares at the Closing. The fee payable to each of Craig-Hallum and Wellington for acting as co-placement agents in connection with the Offering shall be 50% of the Cash Fee. The Cash Fee shall be paid on the Closing Date.

B. In further consideration of the services to be provided for hereunder, the Company shall reimburse the Placement Agents for all reasonable legal, due diligence, travel and other transaction fees incurred, including (a) the fees and expenses of counsel to the Placement Agents in an amount not to exceed $80,000, (b) all fees, expenses and disbursements relating to background checks of the Company’s officers, directors and related entities in an amount not to exceed $5,000 in the aggregate, (c) the filing fees and expenses associated with the review of the Offering by FINRA, and (d) up to $5,000 for other accountable expenses. The Company will make all filings required under the “Blue Sky” laws of those jurisdictions as may be requested by the Placement Agents, and pay all related expenses. If the offering of the Placement Agent Shares and/or the engagement of the Placement Agents as placement agents for the offering of the Placement Agent Shares is terminated before the Closing, then upon such termination, the Company agrees to reimburse the Placement Agents for, and otherwise pay and bear, the full amount of the Placement Agents’ actual accountable “out-of-pocket” expenses validly and actually incurred in connection with the Offering up to the date of termination, in an amount not to exceed $60,000.

C. As additional compensation for the Placement Agents’ services hereunder, the Company shall issue to the Placement Agents or their respective designees unregistered warrants (“Placement Agent Warrants”) to purchase that number of shares of Common Stock equal to 3% of the aggregate number of Shares sold in the Offering. Each of Craig-Hallum and Wellington (or their respective designees) shall be issued 50% of the Placement Agent Warrants for acting as co-placement agents in connection with the Offering. The Placement Agent Warrants will be exercisable at any time and from time to time, in whole or in part, during the four and one-half (4 1/2) year period commencing 180 days from the last date of Closing of the Offering at a price per share equal to 125% of the offering price per Share sold to Purchasers in the Offering.

D. The Company shall pay the compensation set forth in Section 3(A) above, calculated in the manner set forth herein, with respect to any public or private offering of securities or securities convertible into, or exchangeable for, equity securities, or other financing (excluding borrowings by the Company under any credit or lending facility with a bank or other lender) or equity capital-rising transaction of any kind (such transaction, a “Tail Financing”) to the extent that such financing or capital is provided to the Company by investors whom the Placement Agents had contacted, other than officers, directors, and employees of the Company, during the Engagement Period and identified in writing provided to the Company at or prior to the Closing, if such Tail Financing is consummated at any time during the 6-month period following the expiration or termination of this Agreement.

E. Provided that the Shares are sold in accordance with the terms of this Agreement, the Placement Agents shall have an irrevocable right of first refusal (the “Right of First Refusal”), from the closing date of the Offering through the date that is six (6) months after such date (the “ROFR Period”), to act as sole and exclusive investment bankers, sole and exclusive book-runners, sole and exclusive financial advisors, sole and exclusive underwriters and/or sole and exclusive placement agents, at the Placement Agents’ sole and exclusive discretion, for each and every future public and private equity and debt offering, including all equity-linked financings (each, a “Subject Transaction”), during the ROFR Period, of the Company, or any successor to or subsidiary of the Company, on terms and conditions customary to the Placement Agents for such Subject Transactions, provided, that for clarity, this Right of First Refusal shall not apply to Company transactions with strategic partners or other sources of non-dilutive funding, including government agencies and private foundations or for which no broker-dealer is proposed to be engaged by the Company, including offerings of securities by persons other than the Company or equity offerings pursuant to the Company’s equity incentive plans. For the avoidance of any doubt, the Company shall not retain, engage or solicit any additional investment banker, book-runner, financial advisor, underwriter and/or placement agents in a Subject Transaction during the ROFR Period without the express written consent of the Placement Agents. The Company shall notify the Placement Agents of its intention to pursue a Subject Transaction, including the material terms thereof, by providing written notice thereof by e-mail (with confirmation of receipt), registered mail or overnight courier service addressed to the Placement Agents. If the Placement Agents fail to exercise the Right of First Refusal with respect to any Subject Transaction within ten (10) business days after the sending of such written notice, then the Placement Agents shall have no further claim or right with respect to the Subject Transaction. The Placement Agents may elect, in their sole and absolute discretion, not to exercise the Right of First Refusal with respect to any Subject Transaction; provided, that any such election by the Placement Agents shall not adversely affect the Right of First Refusal with respect to any other Subject Transaction during the ROFR Period agreed to above.

F. The Placement Agents reserve the right to reduce any item of compensation or adjust the terms thereof as specified herein in the event that a determination shall be made by FINRA to the effect that the Placement Agents’ aggregate compensation is in excess of FINRA Rules or that the terms thereof require adjustment.

G. The Company represents that except for the commissions payable to the Placement Agents hereunder, there are no commissions or finder’s fees payable by the Company to any other person in connection with the Offering and that the Company shall pay, and hold the Placement Agents harmless against, any liability, loss, or expense (including, without limitation, attorneys’ fees and out-of-pocket expenses) arising in connection with any claim for finder’s fees in connection therewith.

SECTION 4. INDEMNIFICATION.

A. The Company agrees to indemnify and hold harmless the Placement Agents and their respective affiliates (as defined in Rule 405 under the Securities Act of 1933, as amended) and their respective directors, officers, members, managers, employees, agents and controlling persons (the Placement Agents and each such person being an “Indemnified Party”) from and against all losses, claims, damages and liabilities (or actions, including shareholder actions, in respect thereof), joint or several, to which such Indemnified Party may become subject under any applicable federal or state law, or otherwise, which result from the performance by the Placement Agents of the services contemplated by or the engagement of the Placement Agents pursuant to, this Agreement and will promptly reimburse any Indemnified Party for all reasonable expenses (including reasonable counsel fees and expenses, subject to the limitations contain in Section 4(B) hereof) as they are incurred in connection with the investigation of, preparation for or defense arising from any threatened or pending claim, whether or not such Indemnified Party is a party in the pending action or proceeding. The Company will not be liable to any Indemnified Party under the foregoing indemnification and reimbursement provisions, (i) for any settlement by an Indemnified Party effected without its prior written consent (not to be unreasonably withheld); or (ii) to the extent that any loss, claim, damage or liability is found in a final, non-appealable judgment by a court of competent jurisdiction to have resulted from the Placement Agents’ willful misconduct, fraud, bad faith or gross negligence. The Company also agrees that no Indemnified Party shall have any liability (whether direct or indirect, in contract or tort or otherwise) to the Company or its security holders or creditors related to or arising out of the engagement of the Placement Agents pursuant to, or the performance by the Placement Agents of the services contemplated by, this Agreement except to the extent that any loss, claim, damage or liability is found in a final, non-appealable judgment by a court of competent jurisdiction to have resulted primarily from the Placement Agents’ willful misconduct, fraud, bad faith or gross negligence.

B. Promptly after receipt by an Indemnified Party of notice of any intention or threat to commence an action, suit or proceeding or notice of the commencement of any action, suit or proceeding, such Indemnified Party will, if a claim for indemnity in respect thereof is to be made against the Company pursuant hereto, promptly notify the Company in writing of the same. In case any such action is brought against any Indemnified Party and such Indemnified Party notifies the Company of the commencement thereof, the Company shall assume the defense thereof, with counsel reasonably satisfactory to such Indemnified Party, and an Indemnified Party may employ counsel to participate in the defense of any such action provided, that the employment of such counsel shall be at the Indemnified Party’s own expense, unless (i) the employment of such counsel has been authorized in writing by the Company, (ii) the Indemnified Party has reasonably concluded (based upon the written advice of counsel to the Indemnified Party) that there are legal defenses available to it that are different from or in addition to those available to the Company, or that a conflict or potential conflict exists (based upon the written advice of counsel to the Indemnified Party) between the Indemnified Party and the Company that makes it impossible for counsel to the Company to conduct the defense of both the Company and the Indemnified Party (in which case the Company will not have the right to direct the defense of such action on behalf of the Indemnified Party), or (iii) the Company has not in fact employed counsel reasonably satisfactory to the Indemnified Party to assume the defense of such action within a reasonable time after receiving notice of the action, suit or proceeding, in each of which cases the reasonable fees, disbursements and other charges of such counsel will be at the expense of the Company; provided, further, that in no event shall the Company be required to pay fees and expenses for more than one firm of attorneys representing Indemnified Parties unless, in the reasonable written opinion of counsel, the defense of one Indemnified Party is unique or separate from that of another Indemnified Party subject to the same claim or action, and in such event, all of the other Indemnified Parties shall use the same firm of attorneys in connection with such claim or action. Any failure or delay by an Indemnified Party to give the notice referred to in this paragraph shall not affect such Indemnified Party’s right to be indemnified hereunder, except to the extent that such failure or delay causes actual harm to the Company, or prejudices its ability to defend such action, suit or proceeding on behalf of such Indemnified Party.

C. If the indemnification provided for in this Agreement is held unenforceable by or unavailable to an Indemnified Party (except if it is determined by a court of competent jurisdiction in a final non-appealable judgment to have resulted from such Indemnified Party’s misconduct, fraud, bad faith or gross negligence), the Company agrees to contribute to the losses, claims, damages and liabilities for which such indemnification is held unenforceable or unavailable (i) in such proportion as is appropriate to reflect the relative benefits to the Company, on the one hand, and the Placement Agents on the other hand, of the Offering as contemplated whether or not the Offering is consummated or, (ii) if (but only if) the allocation provided for in clause (i) is for any reason unenforceable or unavailable, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause (i) but also the relative fault of the Company, on the one hand and the Placement Agents, on the other hand, as well as any other relevant equitable considerations. The Company agrees that for the purposes of this paragraph the relative benefits to the Company and the Placement Agents of the Offering as contemplated shall be deemed to be in the same proportion that the total value received or contemplated to be received by the Company or its shareholders, as the case may be, as a result of or in connection with the Offering bear to the fees paid or to be paid to the Placement Agents under this Agreement. Notwithstanding the foregoing, the Company expressly agrees that the Placement Agents shall not be required to contribute any amount in excess of the amount by which fees paid the Placement Agents hereunder (excluding reimbursable expenses) exceeds the amount of any damages which the Placement Agents have otherwise been required to pay.

D. The Company will not settle, compromise or consent to the entry of any judgment in any pending or threatened claim, action or proceeding in respect of which indemnification or contribution could be sought under the provisions of this Agreement, if any Indemnified Party is an actual or potential party to such claim, action or proceeding, without the Placement Agents’ prior written consent, which consent shall not be unreasonably withheld in the case of any claim, action or proceeding involving the payment of money damages, unless such settlement, compromise or consent (i) includes an unconditional release of each Indemnified Party from all liability in any way related to or arising out of such claim, action or proceeding and (ii) does not impose any actual or potential liability upon any Indemnified Party and does not contain any factual or legal admission by or with respect to any Indemnified Party or any adverse statement with respect to the character, professionalism, due care, loyalty, expertise or reputation of any Indemnified Party or any action or inaction by any Indemnified Party. The Company’s recourse with respect to any liability or obligation of the Placement Agents hereunder shall be limited to the assets of the Placement Agents, and the Company shall have no recourse against, and expressly waives its right to bring any claim against, any other Indemnified Party or any of their assets.

E. In the event that an Indemnified Party is requested, authorized by the Company, or required to appear as a witness in any action brought by or on behalf of or against the Company for which the Indemnified Party is entitled to reimbursement in which such Indemnified Party is not named as a defendant, the Company agrees to promptly reimburse the Placement Agents on a monthly basis for all reasonable and documented out-of-pocket expenses incurred by it in connection with such Indemnified Party’s appearing and preparing to appear as such a witness, including, without limitation, the reasonable fees and disbursements of its legal counsel.

F. If multiple claims are brought, at least one for which indemnification is permitted under applicable law and provided for under this Agreement, the Company agrees that any judgment or arbitration award shall be conclusively deemed to be based on claims as to which indemnification is permitted and provided for, except to the extent the judgment or arbitration award expressly states that it, or any portion thereof, is based solely on a claim as to which indemnification is not available.

G. The foregoing provisions of this Section 4 are in addition to rights the Placement Agents may have at common law or otherwise, shall inure to the benefit of the Indemnified Parties and their respective successors and assigns and shall be binding on any successor or assign of the Company and successors or assigns to the Company’s business or assets. These indemnification provisions shall remain in full force and effect whether or not the transaction contemplated by this Agreement is completed and shall survive the termination of this Agreement, and shall be in addition to any liability that the Company might otherwise have to any indemnified party under this Agreement or otherwise.

SECTION 5. ENGAGEMENT TERM. The Placement Agents’ engagement hereunder will commence on the date hereof and terminate on the earlier of (i) July 30, 2024 and (ii) the Closing Date (such period, the “Engagement Term”). Notwithstanding anything to the contrary contained herein, the Company agrees that the provisions relating to the Company’s obligation to pay any fees earned pursuant to Section 3 hereof, to pay expenses pursuant to Section 3 hereof, and the provisions relating to indemnification and contribution, confidentiality, conflicts, independent contractor and waiver of the right to trial by jury will survive any termination of this Agreement. The Company agrees that during the Placement Agents’ engagement hereunder, all inquiries, whether direct or indirect, from prospective investors will be referred to the Placement Agents.

The date of termination of this Agreement is referred to herein as the “Termination Date.” In the event, however, in the course of the Placement Agents’ performance of due diligence it deems it necessary to terminate the engagement, the Placement Agents may do so prior to the Termination Date upon delivering written notice to the Company. The Company may elect to terminate the engagement hereunder for any reason prior to the Termination Date but will remain responsible for fees actually earned and expenses actually incurred pursuant to Section 3 hereof and fees with respect to the Placement Agent Shares if sold in the Offering or in one or more transactions to which Section 3(C) applies. If this Agreement is terminated prior to the completion of the Offering, all fees and expenses due to the Placement Agents shall be paid by the Company to the Placement Agents on or before the Termination Date (in the event such fees are earned or owed as of the Termination Date).

SECTION 6. COMPANY AND PLACEMENT AGENTS INFORMATION. The Placement Agents agree not to use any confidential information concerning the Company provided to the Placement Agents by the Company for any purposes other than those contemplated under this Agreement. The Company agrees that any information or advice rendered by the Placement Agents in connection with this engagement is for the confidential use of the Company only in their evaluation of the Offering and, except as otherwise required by law, the Company will not disclose or otherwise refer to the advice or information in any manner without the Placement Agents’ prior written consent; provided, however, that the Company may disclose a copy of this Agreement to (i) its employees, officers, managers and members and (ii) to any investor or prospective investor in the Offering, any acquiror or prospective acquiror of the Company or any underwriter or prospective underwriter, in each case provided that the Company takes reasonable measures to ensure that the recipient of such information treats such information as confidential.

SECTION 7. NO FIDUCIARY RELATIONSHIP. This Agreement does not create, and shall not be construed as creating rights enforceable by any person or entity not a party hereto, except those entitled hereto by virtue of the indemnification provisions hereof. The Company acknowledges and agrees that the Placement Agents are not and shall not be construed as fiduciaries of the Company and shall have no duties or liabilities to the equity holders or the creditors of the Company or any other person by virtue of this Agreement or the retention of the Placement Agents hereunder, all of which are hereby expressly waived.

SECTION 8. CLOSING. The obligations of the Placement Agents, and the closing of the sale of the Placement Agent Shares hereunder, are subject to the accuracy in all material respects (or, to the extent representations or warranties are qualified by materiality or Material Adverse Effect, in all respects), on the Closing Date, of the representations and warranties on the part of the Company contained herein and in the Purchase Agreement (except to the extent a representation or warranty speaks as of a specific date, in which case they such representation or warranty shall be accurate as of such date), to the performance by the Company of its obligations hereunder and in the Purchase Agreement, and to each of the following additional terms and conditions, except as otherwise disclosed to and acknowledged and waived by the Placement Agents:

E. If applicable, FINRA shall have raised no objection to the fairness and reasonableness of the terms and arrangements of this Agreement. In addition, the Company shall, if requested by the Placement Agents, make or authorize Placement Agents’ counsel to make on the Company’s behalf, any filing with the FINRA Corporate Financing Department pursuant to FINRA Rule 5110 with respect to the Offering and pay all filing fees required in connection therewith.

If any of the conditions specified in this Section 8 shall not have been fulfilled when and as required by this Agreement, all obligations of the Placement Agents hereunder may be cancelled by the Placement Agents on, or at any time prior to, the Closing Date. Notice of such cancellation shall be given to the Company in writing or orally. Any such oral notice shall be confirmed promptly thereafter in writing.

SECTION 9. GOVERNING LAW. This Agreement will be governed by, and construed in accordance with, the laws of the State of New York applicable to agreements made and to be performed entirely in such State. This Agreement may not be assigned by either party without the prior written consent of the other party.

Nothing contained herein shall be deemed to limit in any way any right to serve process in any manner permitted by law. If either party shall commence an action or proceeding to enforce any provisions of this Agreement, then the prevailing party in such action or proceeding shall be reimbursed by the other party for its reasonable and documented out-of-pocket attorney’s fees and other costs and expenses incurred in connection with the investigation, preparation and prosecution of such action or proceeding.

This Agreement may not be amended or otherwise modified or waived except by an instrument in writing signed by the Placement Agents and the Company. This Agreement may be executed in two or more counterparts, all of which when taken together shall be considered one and the same agreement and shall become effective when counterparts have been signed by each party and delivered to the other party, it being understood that both parties need not sign the same counterpart.
