ITEM 9A. CONTROLS AND PROCEDURES Evaluation of disclosure controls and procedures. We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in our periodic reports filed with the Securities and Exchange Commission (the “Commission”) is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the Commission and that such information is accumulated and communicated to our management, including the Chief Executive Officer (“CEO”) (Principal Executive Officer), and Chief Financial Officer (“CFO”) (Principal Financial Officer), as appropriate to allow timely decisions regarding the required disclosure. In designing and assessing our disclosure controls and procedures, our management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their stated control objectives and are subject to certain limitations, including the exercise of judgment by individuals, the difficulty in identifying unlikely future events, and the difficulty in eliminating misconduct completely. Our management, with the participation of our CEO and CFO, evaluated the effectiveness of our disclosure controls and procedures pursuant to Rule 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934, as amended. Based upon this assessment, our CEO and CFO have concluded that our disclosure controls and procedures were not effective as of December 31, 2021, due to a material weakness in our internal control over financial reporting as set forth below. Management’s Report on Internal Control over Financial Reporting Our management is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in Rules 13a-15(f) and 15d-15(f) of the Securities Exchange Act of 1934. Internal control over financial reporting is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with accounting principles generally accepted in the United States of America. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements or fraudulent acts. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. A control system, no matter how well designed, can provide only reasonable assurance with respect to financial statement preparation and presentation. Internal control over financial reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the Company; (ii) provide reasonable assurance that transactions are recorded as necessary to permit the preparation of the consolidated financial statements in accordance with generally accepted accounting principles in the United States of America, and that receipts and expenditures of the Company are being made only in accordance with appropriate authorizations of management and directors of the Company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the Company’s assets that could have a material effect on the consolidated financial statements. Management, with the participation of our CEO and CFO, conducted an assessment of the effectiveness of internal control over financial reporting as of December 31, 2021 based on the framework in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”). Based on this assessment, management and our CEO and CFO, concluded that the Company’s internal control over financial reporting was not effective as of December 31, 2021 due to the following: Certain revenue contracts that contained nonstandard terms and conditions were not appropriately evaluated in accordance with ASC 606, “Revenue from Contracts with Customers.” Specifically, management did not have the appropriate controls in place over the determination of revenue recognition for nonroutine and complex revenue transactions. The material weakness identified resulted in errors in the Company's books and records which led to audit adjustments. The errors arising from the underlying revenue adjustments were not material to the financial statements reported in any interim or annual period and therefore, did not result in a revision to any previously filed financial statements. However, the control deficiencies could result in misstatements of the revenue accounts and related disclosures that would result in a material misstatement to the annual or interim consolidated financial statements that would not be prevented or detected in a timely manner. Accordingly, we have determined that the control deficiencies when evaluated in the aggregate constitute a material weakness. Remediation of Material Weakness in Internal Control Over Financial Reporting The material weakness as discussed above was primarily attributed to the uniqueness of certain of the Company’s contracts that contain nonstandard terms and conditions. Although the Company’s policies and procedures were in place to ensure guidance under ASC 606 were applied to the majority of its contracts accurately, the Control failed to operate in a manner to specifically identify the nonstandard terms that would impact revenue recognition. The Company is evaluating the material weakness identified and is developing a plan of remediation to strengthen our internal controls pertaining to evaluating revenue contracts that contain nonstandard terms and conditions. This remediation plan includes evaluating the manner in which we use third-party consulting firms with expertise in applying the revenue recognition guidance that will assist management with the assessment and evaluation of revenue contracts executed that contain nonstandard terms and conditions. In conjunction with further evaluation of this relationship, management will also perform a more rigorous evaluation of these nonstandard revenue contracts in accordance with ASC 606. The Company is committed to maintaining a strong internal control environment and believes that these remediation efforts will represent significant improvements in our controls. The Company has started to implement these steps, however, some of these steps will take time to be fully integrated and confirmed to be effective and sustainable. Additional controls may also be required over time. Until the remediation steps set forth above are fully implemented and tested, the material weakness described above will continue to exist. Grant Thornton LLP, an independent registered public accounting firm, audited the effectiveness of the Company’s internal control over financial reporting as of December 31, 2021 and based on that audit, issued their report which is included herein. Changes in Internal Control over Financial Reporting Other than the aforementioned material weakness and remediation plan noted, there was no other change in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the fiscal quarter ended December 31, 2021 that have materially affected, or are reasonably likely to materially affect, our internal controls over financial reporting. 76 REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM Board of Directors and Stockholders Perma-Fix Environmental Services, Inc. Opinion on internal control over financial reporting We have audited the internal control over financial reporting of Perma-Fix Environmental Services, Inc. (a Delaware corporation) and subsidiaries (the “Company”) as of December 31, 2021, based on criteria established in the 2013 Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”). In our opinion, because of the effect of the material weakness described in the following paragraphs on the achievement of the objectives of the control criteria, the Company has not maintained effective internal control over financial reporting as of December 31, 2021, based on criteria established in the 2013 Internal Control—Integrated Framework issued by COSO. A material weakness is a deficiency, or combination of control deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the company’s annual or interim financial statements will not be prevented or detected on a timely basis. The following material weakness has been identified and included in management’s assessment. Management does not have effective controls in place over the determination of revenue recognition for non-standard revenue contracts. We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (“PCAOB”), the consolidated financial statements of the Company as of and for the year ended December 31, 2021. The material weakness identified above was considered in determining the nature, timing, and extent of audit tests applied in our audit of the 2021 consolidated financial statements, and this report does not affect our report dated April 6, 2022 which expressed an unqualified opinion on those financial statements. Basis for opinion The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion. Definition and limitations of internal control over financial reporting A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. Other information We do not express an opinion or any other form of assurance on management’s statement referring to plans for remediation. /s/ GRANT THORNTON LLP Atlanta, Georgia April 6, 2022 77 ITEM 9B.

The Board believes that this leadership structure promotes balance between the Board’s independent authority to oversee our business, and the CEO and his management team, who manage the business on a day-to-day basis. The Company does not have a written policy with respect to the separation of the positions of Chairman of the Board and CEO. The Company believes it is important to retain its flexibility to allocate the responsibilities of the offices of the Chairman and CEO in any way that is in the best interests of the Company at a given point in time; therefore, the Company’s leadership structure may change in the future as circumstances may dictate. 83 Mr. Mark Zwecker, a current member of our Board, continues to serve as the Independent Lead Director, a position he has held since February 2010. The Lead Director’s role includes: ● convening and chairing meetings of the non-employee directors as necessary from time to time and Board meetings in the absence of the Chairman of the Board; ● acting as liaison between directors, committee chairs and management; ● serving as information sources for directors and management; and ● carrying out such responsibilities as the Board may delegate from time to time. AUDIT COMMITTEE We have a separately designated standing Audit Committee of our Board established in accordance with Section 3(a)(58)(A) of the Exchange Act. Members of the Audit Committee are Mark A. Zwecker (Chairperson), Larry M. Shelton, and Joseph T. Grumski. Our Board has determined that each of our Audit Committee members is and was independent within the meaning of the rules of the NASDAQ and is an “audit committee financial expert” as defined by Item 407(d)(5)(ii) of Regulation S-K of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). The Audit Committee has also discussed with Grant Thornton, LLP, the Company’s independent registered accounting firm, the matters required to be discussed by Public Company Accounting Oversight Board (“PCAOB”) Auditing Standard No. 16 (Communications with Audit Committee). BOARD OF DIRECTOR INDEPENDENCE The Board has determined that each director, other than Dr. Centofanti, is “independent” within the meaning of the applicable NASDAQ rules. Dr. Centofanti is not deemed to be an “independent director” because of his employment as an executive officer of the Company. COMPENSATION AND STOCK OPTION COMMITTEE The Compensation and Stock Option Committee (the “Compensation Committee”) reviews and recommends to the Board the compensation and benefits of all of the Company’s officers and reviews general policy matters relating to compensation and benefits of the Company’s employees. The Compensation Committee also administers the Company’s stock option plans. The Compensation Committee has the sole authority to retain and terminate a compensation consultant, as well as to approve the consultant’s fees and other terms of engagement. It also has the authority to obtain advice and assistance from internal or external legal, accounting or other advisors. No compensation consultant was employed during 2021. Members of the Compensation Committee during 2021 were Joseph T. Grumski (Chairperson), who replaced Larry M. Shelton as the Chairperson and a member effective January 21, 2021, Zach P. Wamp, who replaced Joe R. Reeder as a member effective January 21, 2021, and Mark A. Zwecker. None of the members of the Compensation Committee has been or is an officer or employee of the Company or has had or has any relationship with the Company requiring disclosure under applicable Commission regulations. CORPORATE GOVERNANCE AND NOMINATING COMMITTEE We have a separately-designated standing Corporate Governance and Nominating Committee (the “Nominating Committee”). Members of the Nominating Committee during 2021 were Joe R. Reeder (Chairperson), Zach P. Wamp, Kerry C. Duggan (who became a member effective July 20, 2021) and Thomas Bostick, who replaced Larry M. Shelton as a member effective January 21, 2021. All members of the Nominating Committee are and were “independent” as that term is defined by current NASDAQ listing standards. 84 The Nominating Committee recommends to the Board candidates to fill vacancies on the Board and the nominees for election as directors at each annual meeting of stockholders. In making such recommendation, the Nominating Committee takes into account information provided to them from the candidate, as well as the Nominating Committee’s own knowledge and information obtained through inquiries to third parties to the extent the Nominating Committee deems appropriate. The Company’s Bylaws sets forth certain minimum director qualifications to qualify for nomination for election as a director. To qualify for nomination or for election as a director, an individual must: ● be an individual at least 21 years of age who is not under legal disability; ● have the ability to be present, in person, at all regular and special meetings of the Board of Directors; ● not serve on the boards of more than three other publicly-held companies; ● satisfy the director qualification requirements of all environmental and nuclear commissions, boards or similar regulatory or law enforcement authorities to which the Company is subject so as not to cause the Company to fail to satisfy any of the licensing requirements imposed by any such authority; ● not be affiliated with, employed by or a representative of, or have or acquire a material personal involvement with, or material financial interest in, any “Business Competitor” (as defined in the Bylaws); ● not have been convicted of a felony or of any misdemeanor involving moral turpitude; and ● have been nominated for election to the Board of Directors in accordance with the terms of the Bylaws. In addition to the minimum director qualifications as mentioned above, in order for any proposed nominee to be eligible to be a candidate for election to the Board, such candidate must deliver to the Nominating Committee a completed questionnaire with respect to the background, qualifications, stock ownership and independence of such proposed nominee. The Nominating Committee reviews each candidate’s qualifications to include considerations of: ● standards of integrity, personal ethics and values, commitment, and independence of thought and judgment; ● ability to represent the interests of the Company’s stockholders; ● ability to dedicate sufficient time, energy, and attention to fulfill the requirements of the position; and ● diversity of skills and experience with respect to accounting and finance, management and leadership, business acumen, vision and strategy, charitable causes, business operations, and industry knowledge. The Nominating Committee does not assign specific weight to any particular criteria and no particular criterion is necessarily applicable to all prospective nominees. The Nominating Committee does not have a formal policy for the consideration of diversity in identifying nominees for directors. However, diversity is one of the many factors taken into account when considering potential candidates to serve on the Board of Directors. The Company generally views and values diversity from the perspective of professional and life experiences, as well as geographic location, representative of the markets in which we do business. The Company recognizes that diversity in professional and life experiences may include consideration of gender, race, cultural background or national origin, in identifying individuals who possess the qualifications that the Nominating Committee believes are important to be represented on the Board. The Company believes that the inclusion of diversity as one of many factors considered in selecting director nominees is consistent with the Company’s goal of creating a board of directors that best serves our needs and those of our shareholders. Stockholder Nominees The Nominating Committee will consider properly submitted stockholder nominations for candidates for membership on the Board from stockholders who meet each of the requirements set forth in the Bylaws, including, but not limited to, the requirements that any such stockholder own at least 1% of the Company’s shares of the Common Stock entitled to vote at the meeting on such election, has held such shares continuously for at least one full year, and continuously holds such shares through and including the time of the annual or special meeting. Nominations of persons for election to the Board of Directors may be made at any Annual Meeting of Stockholders, or at any Special Meeting of Stockholders called for the purpose of electing directors. Any stockholder nomination (“Proposed Nominee”) must comply with the requirements of the Company’s Bylaws and the Proposed Nominee must meet the minimum qualification requirements as discussed above. For a nomination to be made by a stockholder, such stockholder must provide advance written notice to the Nominating Committee, delivered to the Company’s principal executive office address (i) in the case of an Annual Meeting of Stockholders, no later than the 90 th day nor earlier than the 120 th day prior to the anniversary date of the immediately preceding Annual Meeting of Stockholders; and (ii) in the case of a Special Meeting of Stockholders called for the purpose of electing directors, not later than the 10 th day following the day on which public disclosure of the date of the Special Meeting of Stockholders is made. 85 The Nominating Committee will evaluate the qualification of the Proposed Nominee and the Proposed Nominee’s disclosure and compliance requirements in accordance with the Company’s Bylaws. If the Board of Directors, upon the recommendation of the Nominating Committee, determines that a nomination was not made in accordance with the Company’s Bylaws, the Chairman of the Meeting shall declare the nomination defective and it will be disregarded. STRATEGIC ADVISORY COMMITTEE We have a separately designated Strategic Advisory Committee (the “Strategic Committee”). The primary functions of the Strategic Committee are to investigate and evaluate strategic alternatives available to the Company and to work with management on long-range strategic planning and identification of potential new business opportunities. The members of the Strategic Advisory Committee are Dr. Louis Centofanti (Chairperson), Joe R. Reeder, Mark A. Zwecker, and Kerry Duggan, who replaced Larry M. Shelton as a member effective July 20, 2021. The Board has adopted a written charter for each of the Audit Committee, the Compensation Committee, the Nominating Committee, and the Strategic Advisory Committee, and is available on our website at www.perma-fix.com .

Section 16(a) Beneficial Ownership Reporting Compliance Section 16(a) of the Exchange Act, and the regulations promulgated thereunder require our executive officers and directors and beneficial owners of more than 10% of our Common Stock to file reports of ownership and changes of ownership of our Common Stock with the Commission, and to furnish us with copies of all such reports. Based solely on a review of the copies of such reports furnished to us and written information provided to us, we believe that during 2021 none of our executive officers, directors, or beneficial owners of more than 10% of our Common Stock failed to timely file reports under Section 16(a). Schelhammer Capital Bank AG (formerly known as Capital Bank-Grawe Gruppe AG) has advised us that it is a banking institution regulated by the banking regulations of Austria, which holds shares of our Common Stock as agent on behalf of numerous investors. Schelhammer Capital Bank AG has represented that all of such investors are accredited investors under Rule 501 of Regulation D promulgated under the Act. In addition, Schelhammer Capital Bank AG has advised us that none of such investors, individually or as a group, beneficially own more than 4.9% of our Common Stock as calculated in accordance with Rule 13d-3 of the Exchange Act. Schelhammer Capital Bank AG has further informed us that its clients (and not Schelhammer Capital Bank AG) maintain full voting and dispositive power over such shares. Consequently, Schelhammer Capital Bank AG has advised us that it believes it is not the beneficial owner, as such term is defined in Rule 13d-3 of the Exchange Act, of the shares of our Common Stock registered in the name of Schelhammer Capital Bank AG because it has neither voting nor investment power, as such terms are defined in Rule 13d-3, over such shares. Schelhammer Capital Bank AG has informed us that it does not believe that it is required to file, and has not filed, (a) reports under Section 16(a) of the Exchange Act or (b) either Schedule 13D or Schedule 13G in connection with the shares of our Common Stock registered in the name of Schelhammer Capital Bank AG. If the representations of, or information provided by Schelhammer Capital Bank AG, are incorrect or Schelhammer Capital Bank AG was historically acting on behalf of its investors as a group, rather than on behalf of each investor independent of other investors, then Schelhammer Capital Bank AG and/or the investor group would have become a beneficial owner of more than 10% of our Common Stock on February 9, 1996, as a result of the acquisition of 1,100 shares of our Preferred Stock that were convertible into a maximum of 256,560 shares of our Common Stock. If either Schelhammer Capital Bank AG or a group of Schelhammer Capital Bank AG’s investors became a beneficial owner of more than 10% of our Common Stock on February 9, 1996, or at any time thereafter, and thereby required to file reports under Section 16(a) of the Exchange Act, then Schelhammer Capital Bank AG has failed to file a Form 3 or any Forms 4 or 5 since February 9, 1996. (See “Item 12 - Security Ownership of Certain Beneficial Owners and Management and Related Stockholder Matter – Security Ownership of Certain Beneficial Owners” for a discussion of Schelhammer Capital Bank AG’s current record ownership of our securities). Code of Ethics Our Code of Ethics applies to all our executive officers and is available on our website at www.perma-fix.com . If any amendments are made to the Code of Ethics or any grants of waivers are made to any provision of the Code of Ethics to any of our executive officers, we will promptly disclose the amendment or waiver and nature of such amendment or waiver on our website at the same web address. 88 ITEM 11.

Option Exercises None of the Company’s NEOs exercised options in 2021. 90 Employment Agreements Each of the NEOs entered into an employment agreement with the Company dated July 22, 2020 (each, an “Employment Agreement” and, collectively, the “Employment Agreements”). Each of the Employment Agreements, which are substantially identical, provides for a specified annual base salary, which annual salary may be increased from time to time, but not reduced, as determined by the Compensation Committee. In addition, each of the NEOs is entitled to participate in the Company’s broad-based benefits plans and to certain performance compensation payable under separate MIPs as approved by the Company’s Compensation Committee and Board. The Company’s Compensation Committee and the Board approved individual 2021 MIPs on January 21, 2021 (which were effective January 1, 2021 and applicable for the 2021 fiscal year) for each of the executive officers (see discussion of each of the 2021 MIPs below under “2021 MIPs”). Each of the Employment Agreements is effective for three years from July 22, 2020 (the “Initial Term”) unless earlier terminated by the Company or by the respective NEO. At the end of the Initial Term of each Employment Agreement, each Employment Agreement will automatically be extended for one additional year, unless at least six months prior to the expiration of the Initial Term, the Company or the respective NEO provides written notice not to extend the terms of the Employment Agreement. Each of the Employment Agreements provides that, if an NEO’s employment is terminated due to death/disability or for cause (as defined in the agreements), the Company will pay to the NEO or to his estate an amount equal to the sum of any unpaid base salary, accrued unused vacation time through the date of termination, any benefits due to the NEO under any employee benefit plan (the “Accrued Amounts”) and any performance compensation payable pursuant to the MIP applicable to such NEO. If the NEO terminates his employment for “good reason” (as defined in the agreements) or is terminated by the Company without cause (including any such termination for “good reason” or without cause within 24 months after a Change in Control (as defined in the agreements), the Company will pay the NEO the Accrued Amounts, two years of full base salary, and two times the performance compensation (under the NEO’s MIP) earned with respect to the fiscal year immediately preceding the date of termination provided the performance compensation earned with respect to the fiscal year immediately preceding the date of termination has not yet been paid. If performance compensation earned with respect to the fiscal year immediately preceding the date of termination has been paid to the NEO, the NEO will be paid an additional year of the performance compensation earned with respect to the fiscal year immediately preceding the date of termination. If the NEO terminates his employment for a reason other than for good reason, the Company will pay to the executive an amount equal to the Accrued Amounts plus any performance compensation payable pursuant to the MIP applicable to such NEO. If there is a Change in Control (as defined in the agreements), all outstanding stock options to purchase the common stock held by the NEO will immediately become exercisable in full commencing on the date of termination through the original term of the options. In the event of the death of an NEO, all outstanding stock options to purchase common stock held by the NEO will immediately become exercisable in full commencing on the date of death, with such options exercisable for the lesser of the original option term or twelve months from the date of the NEO’s death. In the event an NEO terminates his employment for “good reason” or is terminated by the Company without cause, all outstanding stock options to purchase common stock held by the NEO will immediately become exercisable in full commencing on the date of termination, with such options exercisable for the lesser of the original option term or within 60 days from the date of the NEO’s date of termination. Severance benefits payable with respect to a termination (other than Accrued Amounts) shall not be payable until the termination constitutes a “separation from service” (as defined under Treasury Regulation Section 1.409A-1(h)). 91 Potential Payments Upon Termination or Change in Control The following table sets forth the potential (estimated) payments and benefits to which each NEO would be entitled upon termination of employment by the NEO for “good reason” or by the Company “without cause,” or following a Change in Control of the Company, as specified under each of their respective Employment Agreements with the Company, assuming each circumstance described below occurred on December 31, 2021, the last day of our most recent fiscal year. Such potential payments include any Accrued Amounts (accrued base salary earned for 2021 but paid in 2022, as well as accrued unused vacation/sick time and other vested benefits under the Company plans in which he/she participates). The NEO is not entitled to payment of any benefits upon termination for cause or resignation without good reason other than for Accrued Amounts.

(3) Benefit is calculated based on the difference between the exercise price of each option and the market value of the Company’s Common Stock per share (as reported on the NASDAQ) at December 31, 2021 times the number of options outstanding at December 31, 2021. Benefit excludes options which were out-of-the-money at December 31, 2021. 2021 Executive Compensation Components For the fiscal year ended December 31, 2021, the principal components of compensation for executive officers were: ● base salary; ● performance-based incentive compensation; ● long term incentive compensation; ● retirement and other benefits; and ● perquisites. Based on the amounts set forth in the Summary Compensation table, during 2021, salary accounted for approximately 67.4% of the total compensation of our NEOs, while equity option awards, MIP compensation, and other compensation accounted for approximately 32.6% of the total compensation of the NEOs. 92 Base Salary The NEOs, other officers, and other employees of the Company receive a base annual salary. Base salary ranges for executive officers are determined for each executive based on his or her position and responsibility by using market data and comparisons to similar companies within the business segments in which the Company operates. During its review of base salaries for executives, the Compensation Committee primarily considers: ● market data and comparisons to similar companies within the business segments in which the Company operates; ● internal review of the executive’s compensation, both individually and relative to other officers; and ● individual performance of the executive. Salary levels are typically considered annually as part of the performance review process as well as upon a promotion or other change in job responsibility. Merit-based salary increases for executives are based on the Compensation Committee’s assessment of the individual’s performance. The base salary and potential annual base salary adjustments for the NEOs are set forth in their respective employment agreements. On January 20, 2022, the Compensation Committee and the Board approved a cost of living increase of 6.4% to each NEO’s annual base salary, effective January 1, 2022. Such increase was reflected in each of the 2022 MIPs as described below. Performance-Based Incentive Compensation The Compensation Committee has the latitude to design cash and equity-based incentive compensation programs to promote high performance and achievement of our corporate objectives by directors and the NEOs, encourage the growth of stockholder value and enable employees to participate in our long-term growth and profitability. The Compensation Committee may grant stock options and/or performance bonuses. In granting these awards, the Compensation Committee may establish any conditions or restrictions it deems appropriate. In addition, the CEO has discretionary authority to grant stock options to certain high-performing executives or officers, subject to the approval of the Compensation Committee. The exercise price for each stock option granted is at or above the market price of our Common Stock on the date of grant. Stock options may be awarded to newly hired or promoted executives at the discretion of the Compensation Committee. Grants of stock options to eligible newly hired executive officers are generally made at the next regularly scheduled Compensation Committee meeting following the hire date. 2021 MIPs On January 21, 2021, the Compensation Committee and the Board approved individual MIP for the calendar year 2021 for each of the Company’s NEOs. Each of the MIPs was effective January 1, 2021 and applicable for the 2021 fiscal year. Each MIP provides guidelines for the calculation of annual cash incentive-based compensation, subject to Compensation Committee oversight and modification. The performance compensation payable under each MIP was based upon meeting certain of the Company’s separate target objectives during 2021 as described in each of the MIPs below. The Compensation Committee believe performance compensation payable under each of the MIPs should be based on achievement of an EBITDA (earnings before interest, taxes, depreciation and amortization) target, a non- GAAP (“Generally Accepted Accounting Principles”) financial measurement, as the Company believes that this target provides a better indicator of operating performance as it excludes certain non-cash items. EBITDA has certain limitations as it does not reflect all items of income or cash flows that affect the Company’s financial performance under GAAP. Certain targets set forth in each of 2021 MIPs took into account the Board-approved budget for 2021 as well as the Compensation Committee’s expectation for performance that in its estimation would warrant payment of incentive cash compensation. In formulating certain targets, the Compensation Committee and the Board considered 2020 results, economic conditions, potential continued impact of COVID-19 and forecasts for 2021 government spending. Performance compensation, if any, was to be paid on or about 90 days after year-end, or sooner, based on final Form 10-K filing. The Compensation Committee retained the right to modify, change or terminate each MIP and may adjust the various target amounts described below, at any time and for any reason. 93 The total performance compensation that was to be paid to the NEOs under the MIPs was not to exceed 50% of the Company’s pre-tax net income prior to the calculation of performance compensation. The following schedules reflect performance compensation payable under each of the MIPs, along with descriptions of the target objectives. No performance compensation was earned under any of the MIPs for 2021. In February 2021, the Compensation Committee approved a cost of living increase of 2.3% to each NEO’s annual base salary, effective April 1, 2021. This increase was not reflected in the annualize base pay below for each of the 2021 MIPs as approved on January 21, 2021: CEO MIP : Annualized Base Pay: $ 344,400 Performance Incentive Compensation Target (at 100% of Plan): $ 172,200 Total Annual Target Compensation (at 100% of Plan): $ 516,600 Perma-Fix Environmental Serivces, Inc. 2021 Management Incentive Plan CEO MIP MATRIX Target Objectives Performance Target Achieved 60%-74% 75%-89% 90%-110% 111%-129% 130%-150% >150% Revenue (1) (6) $ 1,722 $ 8,610 $ 17,220 $ 29,520 $ 41,820 $ 66,420 EBITDA (2) 10,332 51,660 103,320 177,120 250,920 398,520 Health & Safety (3) (6) 2,583 12,915 25,830 25,830 25,830 25,830 Permit & License Violations (4) (6) 2,583 12,915 25,830 25,830 25,830 25,830 $ 17,220 $ 86,100 $ 172,200 $ 258,300 $ 344,400 $ 516,600 CFO MIP: Annualized Base Pay: $ 280,000 Performance Incentive Compensation Target (at 100% of Plan): $ 140,000 Total Annual Target Compensation (at 100% of Plan): $ 420,000 Perma-Fix Environmental Serivces, Inc. 2021 Management Incentive Plan CFO MIP MATRIX Target Objectives Performance Target Achieved 60%-74% 75%-89% 90%-110% 111%-129% 130%-150% >150% Revenue (1) (6) $ 1,400 $ 7,000 $ 14,000 $ 23,000 $ 31,000 $ 37,000 EBITDA (2) 10,500 52,500 105,000 138,000 186,000 222,000 Health & Safety (3) (6) 1,050 5,250 10,500 10,500 10,500 10,500 Permit & License Violations (4) (6) 1,050 5,250 10,500 10,500 10,500 10,500 $ 14,000 $ 70,000 $ 140,000 $ 182,000 $ 238,000 $ 280,000 94 EVP of Strategic Initiatives MIP: Annualized Base Pay: $ 233,336 Performance Incentive Compensation Target (at 100% of Plan): $ 116,668 Total Annual Target Compensation (at 100% of Plan): $ 350,004 Perma-Fix Environmental Serivces, Inc. 2021 Management Incentive Plan EVP OF STRATEGIC INITIATIVES MIP MATRIX Target Objectives Performance Target Achieved 60%-74% 75%-89% 90%-110% 111%-129% 130%-150% >150% Revenue (1) (6) $ 1,167 $ 5,833 $ 11,667 $ 19,167 $ 25,834 $ 30,834 EBITDA (2) 8,750 43,751 87,501 115,001 155,002 185,002 Health & Safety (3) (6) 875 4,375 8,750 8,750 8,750 8,750 Permit & License Violations (4) (6) 875 4,375 8,750 8,750 8,750 8,750 $ 11,667 $ 58,334 $ 116,668 $ 151,668 $ 198,336 $ 233,336 EVP of Waste Treatment Operations MIP: Annualized Base Pay: $ 240,000 Performance Incentive Compensation Target (at 100% of Plan): $ 120,000 Total Annual Target Compensation (at 100% of Plan): $ 360,000 Perma-Fix Environmental Serivces, Inc. 2021 Management Incentive Plan EVP OF WASTE TREATMENT OPERATIONS MIP MATRIX Target Objectives Performance Target Achieved 60%-74% 75%-89% 90%-110% 111%-129% 130%-150% >150% Revenue (1) (6) $ 1,200 $ 6,000 $ 12,000 $ 17,143 $ 24,000 $ 29,143 EBITDA (2) 7,200 36,000 72,000 102,857 144,000 174,857 Health & Safety (3) (6) 1,800 9,000 18,000 18,000 18,000 18,000 Permit & License Violations (4) (6) 1,800 9,000 18,000 18,000 18,000 18,000 $ 12,000 $ 60,000 $ 120,000 $ 156,000 $ 204,000 $ 240,000 EVP of Nuclear and Technical Services MIP: Annualized Base Pay: $ 280,000 Performance Incentive Compensation Target (at 100% of Plan): $ 140,000 Total Annual Target Compensation (at 100% of Plan): $ 420,000 Perma-Fix Environmental Serivces, Inc. 2021 Management Incentive Plan EVP OF NUCLEAR & TECHNICAL SERVICES MIP MATRIX Target Objective Performance Target Achieved 60%-74% 75%-89% 90%-110% 111%-129% 130%-150% >150% Revenue (1) (6) $ 1,400 $ 7,000 $ 14,000 $ 20,000 $ 28,000 $ 34,000 EBITDA (2) 8,400 42,000 84,000 120,000 168,000 204,000 Health & Safety (3) (6) 2,100 10,500 21,000 21,000 21,000 21,000 CPI (5) (6) 2,100 10,500 21,000 21,000 21,000 21,000 $ 14,000 $ 70,000 $ 140,000 $ 182,000 $ 238,000 $ 280,000 95 (1) Revenue was defined as the total consolidated third-party top line revenue as publicly reported in the Company’s 2021 financial statements.

Each of the MIPs was effective January 1, 2022. The performance compensation payable under each MIP was based upon meeting certain of the Company’s separate target objectives during 2022 as described in each of the MIPs below. Certain targets set forth in each of the 2022 MIPs take into account the Board-approved budget for 2022 as well as the Compensation Committee’s expectation for performance that in its estimation would warrant payment of incentive cash compensation. In formulating certain targets, the Compensation Committee and the Board considered 2021 results, economic conditions, potential continued impact of COVID-19 and forecasts for 2022 government spending. Performance compensation amounts under the 2022 MIPs are to be paid on or about 90 days after year-end, or sooner, based on finalization of our audited financial statements for 2022. The Compensation Committee retains the right to modify, change or terminate each MIP and may adjust the various target amounts described below, at any time and for any reason. The total to be paid to the NEOs under the MIPs shall not exceed 50% of the Company’s pre-tax net income prior to the calculation of performance compensation. The following schedules reflect performance compensation payable under each of the MIPs, along with a description of the target objectives.

Stock options succeed by delivering value to executives only when the value of our stock increases. The 2017 Plan authorizes the grant of Non-Qualified Stock Options (“NQSOs”) and Incentive Stock Options (“ISOs”) for the purchase of our Common Stock. The 2017 Plan assists the Company to: ● enhance the link between the creation of stockholder value and long-term executive incentive compensation; ● provide an opportunity for increased equity ownership by executives; and ● maintain competitive levels of total compensation; Stock option award levels are determined based on market data, vary among participants based on their positions with the Company and are granted generally at the Compensation Committee’s regularly scheduled July or August meeting. Newly hired or promoted executive officers who are eligible to receive options are generally awarded such options at the next regularly scheduled Compensation Committee meeting following their hire or promotion date. Options are awarded with an exercise price equal to or not less than the closing price of the Company’s Common Stock on the date of the grant as reported on the NASDAQ. In certain limited circumstances, the Compensation Committee may grant options to an executive at an exercise price in excess of the closing price of the Company’s Common Stock on the grant date. The Company’s NEOs have outstanding options from the Company’s 2017 Plan (See “Item 11 – Executive Compensation – Outstanding Equity Awards at Fiscal Year-End - Outstanding Equity Awards at December 31, 2021” for outstanding options for each of our NEOs). An option granted to our President and CEO in May 2016 for the purchase of up to 50,000 shares of the Company’s Common Stock at $3.97 per share with an expiration date of May 15, 2022 remains outstanding under the 2010 Stock Option Plan. The 2010 Stock Option Plan expired on September 29, 2020; however, the option remains in effect until the earlier of the exercise date by the optionee or the maturity date of May 15, 2022. In cases of termination of an executive officer’s employment due to death, by the executive for “good reason,” by the Company without cause, and due to a “change of control,” all outstanding stock options to purchase common stock held by the executive officer will immediately become exercisable in full (see further discussion of the exercisability term of these options in each of these circumstances in “Item 11 – EXECUTIVE COMPENSATION – Employment Agreements”). Otherwise, vesting of option awards ceases upon termination of employment and exercise right of the vested option amount ceases upon three months from termination of employment except in the case of retirement (subject to a six-month limitation) and disability (subject to a one-year limitation). Accounting for Stock-Based Compensation We account for stock-based compensation in accordance with ASC 718, “Compensation – Stock Compensation.” ASC 718 establishes accounting standards for entity exchanges of equity instruments for goods or services. It also addresses transactions in which an entity incurs liabilities in exchange for goods or services that are based on the fair value of the entity’s equity instruments or that may be settled by the issuance of those equity instruments. ASC 718 requires all stock-based payments to employees, including grants of employee stock options, to be recognized in the income statement based on their fair values. The Company uses the Black-Scholes option-pricing model to determine the fair-value of stock-based awards which requires subjective assumptions. Assumptions used to estimate the fair value of stock options granted include the exercise price of the award, the expected term, the expected volatility of the Company’s stock over the option’s expected term, the risk-free interest rate over the option’s expected term, and the expected annual dividend yield. We recognize stock-based compensation expense using a straight-line amortization method over the requisite period, which is the vesting period of the stock option grant. 101 Retirement and Other Benefits 401(k) Plan The Company adopted the Perma-Fix Environmental Services, Inc. 401(k) Plan (the “401(k) Plan”) in 1992, which is intended to comply with Section 401 of the Internal Revenue Code and the provisions of the Employee Retirement Income Security Act of 1974. All full-time employees who have attained the age of 18 are eligible to participate in the 401(k) Plan. Eligibility is immediate upon employment but enrollment is only allowed during four quarterly open periods of January 1, Apri1 1, July 1, and October 1. Participating employees may make annual pretax contributions to their accounts up to 100% of their compensation, up to a maximum amount as limited by law. At our discretion, we may make matching contributions based on the employee’s elective contributions. Company contributions vest over a period of five years. In 2021, the Company contributed approximately $589,000 in 401(k) matching funds, of which approximately $32,000 was for our NEOs (see the “Summary Compensation” table in this section for 401(k) matching fund contributions made for the NEOs for 2021). Perquisites and Other Personal Benefits The Company provides executive officers with limited perquisites and other personal benefits (health/disability/life insurance) that the Company and the Compensation Committee believe are reasonable and consistent with its overall compensation program to better enable the Company to attract and retain superior employees for key positions. The Compensation Committee periodically reviews the levels of perquisites and other personal benefits provided to executive officers. The executive officers are provided an auto allowance. Compensation of Directors Directors who are employees receive no additional compensation for serving on the Board or its Board of Directors Committee(s) (the “Committee(s)”). In 2021, the Company provided the following compensation to each non-employee Board member and the Board Committee(s) for which the Board member serves. ● each director was paid a quarterly fee of $11,500; ● the Chairman of the Board was paid an additional quarterly fee of $8,750; ● the Chairman of the Audit Committee was paid an additional quarterly fee of $6,250; ● the Chairman of each of the Compensation Committee, the Nominating Committee, and the Strategic Committee was paid an additional $3,125 in quarterly fees. The Chairman of the Board was not eligible to receive a quarterly fee for serving as the Chairman of any the aforementioned committees; ● each Audit Committee member (excluding the Chairman of the Audit Committee) was paid an additional quarterly fee of $1,250; ● each member of the Compensation Committee, the Nominating Committee, and the Strategic Committee was paid an additional quarterly fee of $500. Such fee was payable only if the member did not also serve as the Chairman of any other standing committees or as the Chairman of the Board; and ● a fee of $1,000 for each board meeting attendance and a $500 fee for meeting attendance via conference call. Each director may elect to have either 65% or 100% of such fees payable in Common Stock under the 2003 Outside Directors Stock Option Plan (“2003 Outside Directors Plan”), with the balance, if any, payable in cash. Prior to July 20, 2021, each non-employee director was also provided an option to purchase 6,000 and 2,400 shares of the Company’s Common Stock upon initial election and re-election, respectively, with each option having a 10-year term and being fully vested after six months from date grant date. On July 20, 2021, at the Company’s Annual Meeting of Stockholders, the Company’s stockholders approved an amendment to the Company’s 2003 Outside Directors Plan which provided the following, among other thing: increased (a) the number of shares of Common Stock subject to the automatic option grant made to each non-employee director upon initial election, from 6,000 to 20,000 shares, (b) increased the number of shares of Common Stock subject to the automatic option grant made to each non-employee director upon reelection, from 2,400 to 10,000 shares, and (c) amended the vesting period of options granted under the plan, from a six-month vesting period to 25% per year, beginning on the first anniversary date of the grant. 102 Dr. Louis Centofanti, a current member of the Board, is not eligible to receive compensation for his service as a director of the Company as he is an employee of the Company (see “Summary Compensation” table in this section for Dr. Centofanti’s annual salary and other compensation as an employee of the Company). The table below summarizes the director compensation expenses recognized by the Company for director options and stock awards (resulting from fees earned) for the year ended December 31, 2021. The terms of the 2003 Outside Directors Plan are further described below under “2003 Outside Directors Plan.” Director Compensation Name Fees Earned or Paid In Cash Stock Awards Option Awards Non-Equity Incentive Plan Compensation Nonqualified Deferred Compensation Earnings All Other Compensation Total ($) (1) ($) (2) ($) (4) ($) ($) ($) ($) Thomas P.

Zwecker 26,600 65,873 38,000 (3) — — — 130,473 (1) Under the 2003 Outside Directors Plan, each director elects to receive 65% or 100% of the director’s fees in shares of our Common Stock. The amounts set forth above represent the portion of the director’s fees paid in cash and exclude the value of the director’s fee elected to be paid in Common Stock under the 2003 Outside Directors Plan, which values are included under “Stock Awards.” (2) The number of shares of Common Stock comprising stock awards granted under the 2003 Outside Directors Plan is calculated based on 75% of the closing market value of the Common Stock as reported on the NASDAQ on the business day immediately preceding the date that the quarterly fee is due. Such shares are fully vested on the date of grant. The value of the stock award is based on the market value of our Common Stock at each quarter end times the number of shares issuable under the award. The amount shown is the fair value of the Common Stock on the date of the award. (3) Reflects options granted under the Company’s 2003 Outside Directors Plan resulting from re-election to the Board on July 20, 2021. Options are for a 10-year period with an exercise price of $5.93 per share and vest 25% per year, beginning on the first anniversary date of the grant. The value of the option award for each outside director is calculated based on the fair value of the option per share (approximately $3.80) on the date of grant times the number of options granted, which was 10,000 for each director, pursuant to ASC 718, “Compensation – Stock Compensation.” Option awards for Kerry C. Duggan also included the grant of an option for the purchase of up to 6,000 shares of our Common Stock upon initial election to the Board on May 4, 2021. The options have a 10-year term with an exercise price of $7.50 per share and are fully vested six months from date of grant. The fair value of the 6,000 options was determined to be approximately $30,000 based on fair value of $4.97 per share. 103 (4) The following table reflects the aggregate number of outstanding NQSO held by the Company’s directors at December 31, 2021. As an employee of the Company or its subsidiaries, Dr. Centofanti is not eligible to participate in the 2003 Outside Directors Plan. Options reflected below for Dr. Centofanti were granted from the 2017 Plan as discussed previously: Options Outstanding at Name December 31, 2021 Dr. Louis Centofanti 85,000 Thomas P. Bostick 16,000 Kerry C. Duggan 16,000 Joseph T. Grumski 18,400 Joe R. Reeder 31,600 Larry M. Shelton 31,600 Zach P. Wamp 23,200 Mark A. Zwecker 31,600 Total 253,400 2003 Outside Directors Plan We believe that it is important for our directors to have a personal interest in our success and growth and for their interests to be aligned with those of our stockholders; therefore, under our 2003 Outside Directors Plan, as amended, each outside director is granted a 10-year option to purchase up to 20,000 shares of Common Stock on the date such director is initially elected to the Board, and receives on each re-election date an option to purchase up to another 10,000 shares of our Common Stock, with the exercise price being the fair market value of the Common Stock preceding the option grant date. Common Stock shares subject to option granted vest at 25% per year, beginning on the first anniversary date of the grant and no option shall be exercisable after the expiration of ten years from the date the option is granted. At December 31, 2021, options to purchase 204,400 shares of Common Stock were outstanding under the 2003 Outside Directors Plan, of which 134,400 were vested at December 31, 2021. As a member of the Board, each director may elect to receive either 65% or 100% of his director’s fee in shares of our Common Stock. The number of shares received by each director is calculated based on 75% of the fair market value of the Common Stock determined on the business day immediately preceding the date that the quarterly fee is due. The balance of each director’s fee, if any, is payable in cash. In 2021, the fees earned by our outside directors totaled approximately $556,000. Reimbursements of expenses for attending meetings of the Board are paid in cash at the time of the applicable Board meeting. As a management director, Dr. Centofanti is not eligible to participate in the 2003 Outside Directors Plan. As of December 31, 2021, we have issued 775,346 shares of our Common Stock in payment of director fees since the inception of the 2003 Outside Directors Plan. In the event of a “change of control” (as defined in the 2003 Outside Directors Plan), each outstanding stock option and stock award shall immediately become exercisable in full notwithstanding the vesting or exercise provisions contained in the stock option agreement. ITEM 12. SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT AND RELATED STOCKHOLDER MATTERS Security Ownership of Certain Beneficial Owners The table below sets forth information as to the shares of Common Stock beneficially owned as of February 14, 2022 by each person known by us to be the beneficial owners of more than 5% of any class of our voting securities. Name of Beneficial Owner Title Of Class Amount and Nature of Ownership Percent Of Class (1) Heartland Advisors, Inc. (2) Common 1,141,000 8.6 % (1) The number of shares and the percentage of outstanding Common Stock shown as beneficially owned by a person are based upon 13,234,430 shares of Common Stock outstanding on February 14, 2022, and the number of shares of Common Stock which such person has the right to acquire beneficial ownership of within 60 days. Beneficial ownership by our stockholders has been determined in accordance with the rules promulgated under Section 13(d) of the Exchange Act. 104 (2) This information is based on the Schedule 13D of Heartland Advisors, Inc., an investment advisor, filed with the Commission on November 16, 2021 disclosing that at November 12, 2021, each Heartland Advisors, Inc. and Mr. William Nasgovitz, as a control person of Heartland Advisors, Inc. had shared dispositive power over all shares shown above and shared voting power over 1,045,500 of such shares. The address of Heartland Advisors, Inc. is 789 North Water Street, Milwaukee, WI 53202. Additionally, Schelhammer Capital Bank AG, a banking institution regulated by the banking regulations of Austria, has represented to the Company that as of February 1, 2022, it holds of record as a nominee for, and as an agent of, certain accredited investors, 2,073,983 shares of our Common Stock. None of the Common Stock held by Schelhammer Capital Bank AG for the account of any single investor represents more than 4.9% of our Common Stock and to the best knowledge of Schelhammer Capital Bank AG, as far as stocks held by such investors in accounts with Schelhammer Capital Bank AG, none of such investors act together as a group or otherwise act in concert for the purpose of voting on matters subject to the vote of our stockholders or for purpose of disposition or investment of such stock. Additionally, the investors for whom Schelhammer Capital Bank AG acts as nominee with respect to such shares maintain full voting and dispositive power over the Common Stock beneficially owned by such investors, and Schelhammer Capital Bank AG has neither voting nor investment power over such shares. Accordingly, Schelhammer Capital Bank AG believes that (i) it is not the beneficial owner, as such term is defined in Rule 13d-3 of the Exchange Act, of the shares of Common Stock registered in Schelhammer Capital Bank AG’s name because (a) Schelhammer Capital Bank AG holds the Common Stock as a nominee only, (b) Schelhammer Capital Bank AG has neither voting nor investment power over such shares, and (c) Schelhammer Capital Bank AG has not nominated or sought to nominate, and does not intend to nominate in the future, any person to serve as a member of our Board; and (ii) it is not required to file reports under Section 16(a) of the Exchange Act or to file either Schedule 13D or Schedule 13G in connection with the shares of our Common Stock registered in the name of Schelhammer Capital Bank AG. Notwithstanding the previous paragraph, if Schelhammer Capital Bank AG’s representations to us described above are incorrect or if the investors for whom Schelhammer Capital Bank AG acts as nominee are acting as a group, then Schelhammer Capital Bank AG or a group of such investors could be a beneficial owner of more than 5% of our voting securities. If Schelhammer Capital Bank AG was deemed the beneficial owner of such shares, the following table sets forth information as to the shares of voting securities that Schelhammer Capital Bank AG may be considered to beneficially own on February 1, 2022: Name of Record Owner Title Of Class Amount and Nature of Ownership Percent Of Class (*) Schelhammer Capital Bank AG Common 2,073,983 (+) 15.7 % (*) This calculation is based upon 13,234,430 shares of Common Stock outstanding on February 14, 2022, plus the number of shares of Common Stock which Schelhammer Capital Bank AG, as agent for certain accredited investors has the right to acquire within 60 days, which is none. (+) This amount is the number of shares that Schelhammer Capital Bank AG has represented to us that it holds of record as nominee for, and as an agent of, certain accredited investors. As of February 1, 2022, the date of Schelhammer Capital Bank AG’s representations to us, Schelhammer Capital Bank AG has no warrants or options to acquire, as agent for certain investors, additional shares of our Common Stock. Although Schelhammer Capital Bank AG is the record holder of the shares of Common Stock described in this note, Schelhammer Capital Bank AG has advised us that it does not believe it is a beneficial owner of the Common Stock or that it is required to file reports under Section 16(a) or Section 13(d) of the Exchange Act. Schelhammer Capital Bank AG has advised us that it (a) holds the Common Stock as a nominee only and that it does not exercise voting or investment power over the Common Stock held in its name and that no one investor for which it holds our Common Stock holds more than 4.9% of our issued and outstanding Common Stock and (b) has not nominated, and has not sought to nominate, and does not intend to nominate in the future, any person to serve as a member of our Board. Accordingly, we do not believe that Schelhammer Capital Bank AG is our affiliate. Schelhammer Capital Bank AG’s address is Goldschmiedgasse 3, A-1010 Wien, Austria. 105 Security Ownership of Management The following table sets forth information as to the shares of voting securities beneficially owned as of February 14, 2022, by each of our directors and NEOs and by all of our directors and NEOs as a group.

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS, AND DIRECTOR INDEPENDENCE We describe below transactions to which we were a party during our last two fiscal years or to which we currently propose to be a party in the future, and in which: ● the amounts involved exceeded or will exceed the lesser of $120,000 or one percent of the average of our total assets at year-end for the last two completed fiscal years; and 107 ● any of our directors, executive officers or beneficial owners of more than 5% of any class of our voting securities, or any member of the immediate family of the foregoing persons, had or will have a direct or indirect material interest. Audit Committee Review Our Audit Committee Charter provides for the review by the Audit Committee of any related party transactions, other than transactions involving an employment relationship with the Company, which are reviewed by the Compensation Committee. Although we do not have written policies for the review of related party transactions, the Audit Committee reviews transactions between the Company and its directors, executive officers, holders of more than 5% of any class of the Company’s voting securities, and their respective immediate family members. In reviewing a proposed transaction, the Audit Committee takes into account, among other factors it deems appropriate: (1) the extent of the related person’s interest in the transaction; (2) whether the transaction is on terms generally available to an unaffiliated third-party under the same or similar circumstances; (3) the cost and benefit to the Company; (4) the impact or potential impact on a director’s independence in the event the related party is a director, an immediate family member of a director or an entity in which a director is a partner, stockholder or executive officer; (5) the availability of other sources for comparable products or services; (6) the terms of the transaction; and (7) the risks to the Company. In addition, as applicable, the Audit Committee considers Section 144 of the Delaware General Corporation Law (“DGCL”) and the Company’s Code of Ethics. The provisions of Section 144 of the DGCL apply to transactions between the Company and any of its officers or directors, or any organization in which any such individual has a financial interest or serves as a director or officer (individually, a “Section 144 Related Party,” and, collectively, “Section 144 Related Parties”). Section 144 provides that a transaction between a corporation and any Section 144 Related Party will not be void or voidable solely because such transaction involves the corporation and the Section 144 Related Party, or solely because the Section 144 Related Party is present at or participates or votes in the meeting of the board or committee which authorizes the transaction, if the transaction (a) is approved in good faith after full disclosure of the material facts of the transaction by a majority vote of (i) the disinterested directors, or (ii) the stockholders, and (b) is fair as to the corporation as of the time it is authorized, approved, or ratified by the board, a committee or the stockholders. The provisions of the Code of Ethics apply to our NEOs and provides that such individuals must exhibit and promote honest and ethical conduct in connection with the performance of his or her duties for and on behalf of the Company, including the ethical handling of actual or apparent conflicts of interest involving such individual and the Company, by, among other considerations: ● not entering into a transaction that would result in a conflict of interest with what is in the best interest of the Company and that is reasonably likely to result in material personal gain to any such individuals or their affiliates; ● not having a personal financial interest in any of the Company’s suppliers, customers or competitors that could cause divided loyalty as a result of having the ability to influence the Company’s decisions with that particular supplier or customer or actions to be taken by the Company that could materially benefit a competitor. Related party transactions are reviewed by the Audit Committee prior to the consummation of the transaction. With respect to a related party transaction arising between Audit Committee meetings, the CFO may present it to the Audit Committee Chairperson, who will review and may approve the related party transaction subject to ratification by the Audit Committee at the next scheduled meeting. Our Audit Committee shall approve only those transactions that, in light of known circumstances, are not inconsistent with the Company’s best interests. 108 Related Party Transactions David Centofanti David Centofanti serves as our Vice President of Information Systems. For such position, he received annual compensation of $184,000 and $181,000 for 2021 and 2020, respectively. David Centofanti is the son of Dr. Louis F. Centofanti, our EVP of Strategic Initiatives and a Board member. Board Independence Our Common Stock is listed on the Nasdaq Capital Market. Rule 5605 of the Nasdaq Marketplace Rules requires a majority of a listed company’s board of directors to be comprised of independent directors. In addition, the Nasdaq Marketplace Rules require that, subject to specified exceptions, each member of a listed company’s audit, compensation and nominating and corporate governance committees be independent under applicable provisions of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). Audit committee members must also satisfy independence criteria set forth in Rule 10A-3 under the Exchange Act, and compensation committee members must also satisfy the independence criteria set forth in Rule 10C-1 under the Exchange Act. Under Nasdaq Rule 5605(a)(2), a director will only qualify as an “independent director” if, in the opinion of our Board, that person does not have a relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director. In order to be considered independent for purposes of Rule 10A-3 under the Exchange Act, a member of an audit committee of a listed company may not, other than in his or her capacity as a member of the audit committee, the board of directors, or any other board committee, accept, directly or indirectly, any consulting, advisory, or other compensatory fee from the listed company or any of its subsidiaries or otherwise be an affiliated person of the listed company or any of its subsidiaries. In order to be considered independent for purposes of Rule 10C-1, the board must consider, for each member of a compensation committee of a listed company, all factors specifically relevant to determining whether a director has a relationship to such company which is material to that director’s ability to be independent from management in connection with the duties of a compensation committee member, including, but not limited to: the source of compensation of the director, including any consulting advisory or other compensatory fee paid by such company to the director; and whether the director is affiliated with the company or any of its subsidiaries or affiliates. Our Board annually undertakes a review of the composition of our Board of Directors and its committees and the independence of each director. Based upon information requested from and provided by each director concerning his background, employment and affiliations, including family relationships, our Board of Directors has determined that Ms. Kerry C. Duggan and each of Messrs. Thomas P. Bostick, Joseph T. Grumski, Joe R. Reeder, Larry M. Shelton, Zach P. Wamp and Mark A. Zwecker is an “independent director” as defined under the Nasdaq Marketplace Rules. Our Board of Directors has also determined that each member of our Audit Committee, consisting of Mark A. Zwecker (Chairperson), Joseph T. Grumski, and Larry M. Shelton, and each member of our Compensation Committee, consisting of Joseph T. Grumski (who became a member and the Chairperson effective January 21, 2021), Zach P. Wamp (who became a member effective January 21, 2021), Mark A. Zwecker, Larry M. Shelton (who was replaced by Joseph T. Grumski as a member and the Chairperson effective January 21, 2021), and Joe R. Reeder (who was replaced by Zach P. Wamp as a member effective January 21, 2021) satisfy/satisfied the independence standards for such committees established by the Commission and the Nasdaq Marketplace Rules, as applicable. In making such determination, our Board of Directors considered the relationships that each such non-employee director has with our Company and all other facts and circumstances our Board of Directors deemed relevant in determining independence, including the beneficial ownership of our capital stock by each non-employee director. Our Board of Directors has determined that Dr. Centofanti is not deemed to be an “independent director” because of his employment as a senior executive of the Company. 109 ITEM 14. PRINCIPAL ACCOUNTANT FEES AND SERVICES The following table reflects the aggregate fees for the audit and other services provided by Grant Thornton LLP, the Company’s independent registered public accounting firm, for fiscal years 2021 and 2020: Fee Type 2021 2020 Audit Fees (1) $ 968,000 $ 573,000 Tax Fees (2) 146,000 104,000 Total $ 1,114,000 $ 677,000 (1) Audit fees consist of audit work performed in connection with the annual financial statements, the reviews of unaudited quarterly financial statements, and work generally only the independent registered accounting firm can reasonably provide, such as consents and review of regulatory documents filed with the Securities and Exchange Commission. (2) Fees for income tax planning, filing, and consulting. Engagement of the Independent Auditor To ensure that our independent registered public accounting firm is engaged only to provide audit and non-audit services that are compatible with maintaining its independence, the Audit Committee has a policy that requires the Committee to review and approve in advance all services to be provided by the Company’s independent accounting firm before the firm is engaged to provide those services. The Audit Committee considers non-audit services and fees when assessing auditor independence, and determined that tax return preparation and other tax compliance services is compatible with maintaining our accounting firm’s independence. All services under the headings Audit Fees and Tax Fees were approved by the Audit Committee pursuant to paragraph (c)(7)(i)(C) of Rule 2-01 of Regulation S-X of the Exchange Act. The Audit Committee’s pre-approval policy provides as follows: ● The Audit Committee will review and pre-approve on an annual basis all audits, audit-related, tax and other services, along with acceptable cost levels, to be performed by the independent accounting firm and any member of the independent accounting firm’s alliance network of firms, and may revise the pre-approved services during the period based on later determinations. Pre-approved services typically include: audits, quarterly reviews, regulatory filing requirements, consultation on new accounting and disclosure standards, employee benefit plan audits, reviews and reporting on management’s internal controls and specified tax matters. ● Any proposed service that is not pre-approved on the annual basis requires a specific pre-approval by the Audit Committee, including cost level approval. ● The Audit Committee may delegate pre-approval authority to one or more of the Audit Committee members. The delegated member must report to the Audit Committee, at the next Audit Committee meeting, any pre-approval decisions made. PART IV ITEM 15.
