Exhibit 10.1

SEPARATION AND CONSULTING AGREEMENT

This Separation and Consulting Agreement (this “Separation Agreement”) between CECO Environmental Corp. (the “Company”) and Dennis Sadlowski (“you” and similar words) sets forth certain terms of your separation from the Company, including certain terms required under the Executive Employment Agreement, dated June 10, 2017, between the Company and you (the “Employment Agreement”) or otherwise, in order for you to receive certain separation payments and benefits, as set forth in detail below.

By signing this Separation Agreement, you and the Company agree as follows:

1.Status of Employment

You agree that you will terminate from your position as Chief Executive Officer of the Company effective July 5, 2020 (the “Separation Date”).  You also agree that, as of the Separation Date, you will resign from all other positions (including any directorships) you hold with, and as an employee of, the Company and the Company’s subsidiaries and affiliates, as applicable, and that you will promptly execute any documents and take any actions as may be necessary or reasonably requested by the Company to effectuate or memorialize your termination from all positions with the Company and its subsidiaries and affiliates.  You agree that the terminations described in this Paragraph 1 shall be treated as set forth in Paragraph 2 of this Separation Agreement.

2.Severance Benefits

Within 30 days after the Separation Date, the Company will pay to you a lump sum in cash representing your Accrued Obligations (as defined in the Employment Agreement), which will consist of the following, all subject to applicable tax withholding:

In consideration for you (a) signing this Separation Agreement, and (b) signing, no earlier than the Separation Date and no later than 52 days following the Separation Date, a general waiver and release of claims, substantially in the form attached hereto as Exhibit A (the “Release”), and letting the Release become effective as set forth in the Release, (I) for purposes of your Employment Agreement and this Separation Agreement, your separation from the Company will be deemed a termination of your employment without Cause (as defined in the Employment Agreement), and (II) you will receive the payments and benefits as specified on

Exhibit B attached hereto, all subject to applicable tax withholding (the “Severance Benefits”).  

The Accrued Obligations and the Severance Benefits will be in full satisfaction of any amounts due under the Employment Agreement, the CECO Environmental Corp. 2017 Equity and Incentive Compensation Plan (the “Equity Plan”), and other compensation arrangements of the Company.  You acknowledge and agree that the Severance Benefits do not constitute a benefit to which you would otherwise be entitled as a result of your employment with the Company, that the Severance Benefits would not be due unless you sign the Release, and that the Severance Benefits constitute fair and adequate consideration for your promises and covenants set forth in this Separation Agreement and the Release.

3.Consulting

To assist the Company with the transition of your responsibilities and duties as an independent advisor to the Company’s Chief Executive Officer and the Company’s management team, during the period from July 6, 2020 through December 31, 2020 (the “Consulting Period”), you will provide consultation to the Company on a non-exclusive basis as a consultant on such matters related to the Company, its business, operations, customer relations and industry associations, and industries it serves, as the Company’s Chief Executive Officer or his designee may reasonably request (“Consulting Services”), subject to the following terms and conditions:

Notwithstanding the foregoing, the Consulting Period and the Consulting Services will terminate automatically upon your death or disability.

The Company shall reimburse you for all reasonable and documented expenses incurred by you at the request of the Company in the performance of the Consulting Services under this Separation Agreement.  You shall not be obligated to make any advance to or for the account of the Company, nor shall you be obligated to incur any expense for the account of the Company without assurance that the necessary funds for the discharge of such expense will be provided.  Notwithstanding the foregoing, all significant expenses to be incurred by you in connection with the Consulting Services shall require the prior written (including e-mail) approval of the Chief Executive Officer of the Company.  If any reimbursements or in-kind benefits provided by the Company pursuant to this Separation Agreement would constitute deferred compensation for purposes of Section 409A of the Internal Revenue Code of 1986, as amended, such reimbursements or in-kind benefits shall be subject to the following rules: (a) the amounts to be reimbursed, or the in-kind benefits to be provided, shall be determined pursuant to the terms of the applicable benefit plan, policy or agreement and shall be limited to your lifetime and the lifetime of your eligible dependents; (b) the amount eligible for reimbursement, or the in-kind benefits provided, during any calendar year may not affect the expenses eligible for reimbursement, or the in-kind benefits provided, in any other calendar year; (c) any reimbursement of an eligible expense shall be made on or before the last day of the calendar year following the calendar year in which the expense was incurred; and (d) your right to an in-kind benefit or reimbursement is not subject to liquidation or exchange for cash or another benefit.

4.Restrictive Covenants

By signing this Separation Agreement, you reaffirm that you will continue to abide by the applicable covenants set forth in Section 8 of the Employment Agreement, and the Company reaffirms that it will continue to abide by the applicable non-disparagement covenants set forth in Section 8(k) of the Employment Agreement, which in each case expressly survive the termination of your employment without Cause.  Notwithstanding anything in this Separation Agreement or the Employment Agreement to the contrary, nothing in this Separation Agreement or the Employment Agreement prevents you from providing, without prior notice to the Company, information to governmental authorities regarding possible legal violations or otherwise testifying or participating in any investigation or proceeding by any governmental authorities regarding possible legal violations, and for purpose of clarity you are not prohibited from providing information voluntarily to the Securities and Exchange Commission pursuant to Section 21F of the Securities Exchange Act of 1934, as amended.

5.Limitations

Nothing in this Separation Agreement, the Employment Agreement or the Release shall be binding upon the parties to the extent it is void or unenforceable for any reason, including, without limitation, as a result of any law regulating competition or proscribing unlawful business practices; provided, however, that to the extent that any provision in this Separation Agreement, the Employment Agreement or the Release could be modified to render it enforceable under applicable law, it shall be deemed so modified and enforced to the fullest extent allowed by law.

6.Other Acknowledgements

No Company policy or individual agreement between the Company and you shall prevent you from providing information to government authorities regarding possible legal violations, participating in investigations, testifying in proceedings regarding the Company’s past or future conduct, engaging in any future activities protected under the whistleblower statutes administered by any government agency (e.g., EEOC, NLRB, SEC, etc.) or receiving a monetary award from a government-administered whistleblower award program for providing information directly to a government agency. The Company nonetheless asserts and does not waive its attorney-client privilege over any information appropriately protected by privilege.  By executing this Separation Agreement you represent that, as of the date you sign this Separation Agreement, no claims, lawsuits, or charges have been filed by you or on your behalf against the Company or any of its legal predecessors, successors, assigns, fiduciaries, parents, subsidiaries, divisions or other affiliates, or each of the foregoing’s respective past, present and future principals, partners, shareholders, directors, officers, employees, agents, consultants, attorneys, trustees, administrators, executors or representatives (the “Released Parties”).  You acknowledge and agree that you have in a timely manner received or waived all applicable notices required under the Employment Agreement in connection with the termination of your employment with the Company.  The Company agrees that this Separation Agreement does not extend to, release or modify any rights to indemnification or advancement of expenses to which you are entitled from the Company or its insurers under the Company’s certificate of incorporation, by-laws, or other corporate governing law or instruments.

7.Certain Claims

The Company’s obligation to make the payments and provide the benefits provided for in this Separation Agreement and otherwise to perform its obligations hereunder shall be subject to set-off, counterclaim, recoupment, defense, or other claim, right or action that the Company may have against you (but the Company represents and warrants that it has no actual knowledge of any matter that would give rise to a set-off, counterclaim, recoupment, or defense, or constitute a claim, right, or action against you as of your Separation Date) to the extent such set-off or other action does not violate Section 409A of the Internal Revenue Code of 1986, as amended.  You will be entitled to recover actual damages if the Company breaches this

Separation Agreement, including any unexcused late or non-payment of any amounts owed under this Separation Agreement, or any unexcused failure to provide any other benefits specified in this Separation Agreement.  Failure by either party to enforce any term or condition of this Separation Agreement at any time shall not preclude that party from enforcing that provision, or any other provision, at a later time.

8.No Re-Employment

You understand that your employment with the Company terminates on the Separation Date.  Except for your performance of the Consulting Services during the Consulting Period, you agree that you will not seek or accept employment with the Company, including assignment to or on behalf of the Company as an independent contractor or through any third party, and the Company has no obligation to consider you for any future employment or assignment.

9.Review of Separation Agreement

This Separation Agreement is important.  You are advised to review it carefully and consult an attorney before signing it, as well as any other professional whose advice you value, such as an accountant or financial advisor.  If you agree to the terms of this Separation Agreement, sign in the space below where your agreement is indicated.  The payments and benefits specified in this Separation Agreement are contingent on your signing this Separation Agreement and the Release no earlier than the Separation Date and no later than 52 calendar days following the Separation Date, and not revoking the Release.

10.Return of Property

Except as otherwise provided in Exhibit B, you affirm that you have, or will have within a reasonable time after the date of this Separation Agreement, returned to the Company, including in reasonable working order, all Company Property, as described more fully below.  “Company Property” includes company-owned computers, tablets, mobile phones, motor vehicles, equipment, supplies and documents.  Such documents may include but are not limited to customer information, supplier information, product information, financial statements, cost data, price lists, invoices, forms, passwords, electronic files and media, mailing lists, contracts, reports, manuals, personnel files, correspondence, business cards, drawings, employee lists or directories, lists of vendors, photographs, maps, surveys, and the like, including copies, notes or compilations made there from, whether such documents are embodied on “hard copies” or contained on computer disk or any other medium.  You further agree that you will not retain any copies or duplicates of any such Company Property.

11.Future Cooperation

You agree that you shall respond to reasonable requests for information from the Company regarding matters that may arise in the Company’s business.  You further

agree to fully and completely cooperate with the Company, its advisors and its legal counsel with respect to any litigation that is pending against the Company and any claim or action that may be filed against the Company in the future.  Such cooperation shall include making yourself available at reasonable times and places for interviews, reviewing documents, testifying in a deposition or a legal or administrative proceeding, and providing advice to the Company in preparing defenses to any pending or potential future claims against the Company.  To the extent that, following the Consulting Period, responding to such information requests and/or cooperation (other than with respect to matters, litigation, claims, or actions that arise out of purported acts or omissions by you) requires more than a customarily reasonable amount of time investment by you, the Company will pay you a reasonable per diem or hourly rate that is reasonably agreed to in good faith by you and the Company (which agreement will not be unreasonably withheld).  The Company further agrees to pay/reimburse you for any approved travel expenses reasonably incurred as a result of your cooperation with the Company, with any such payments/reimbursements to be made in accordance with the Company's expense reimbursement policy as in effect from time to time.

12.Tax Matters

By signing this Separation Agreement, you acknowledge that you will be solely responsible for any taxes which may be imposed on you as a result of the Accrued Obligations and the Severance Benefits, all amounts payable to you under this Separation Agreement will be subject to applicable tax withholding by the Company, and the Company has not made any representations or guarantees regarding the tax result for you with respect to any income recognized by you in connection with this Separation Agreement, the Accrued Obligations or the Severance Benefits.

13.Nature of Agreement

By signing this Separation Agreement, you acknowledge that you are doing so freely, knowingly and voluntarily. You acknowledge that in signing this Separation Agreement you have relied only on the promises written in this Separation Agreement and not on any other promise made by the Released Parties, the Company or any past, present or future parents, subsidiaries or affiliates of the Company (collectively, the “CECO Companies”).  This Separation Agreement is not, and will not be considered, an admission of liability or of a violation of any applicable contract, law, rule, regulation, or order of any kind.  This Separation Agreement and the Release contains the entire agreement between the Company, other CECO Companies and you regarding your departure from the Company, except that all post-employment covenants contained in the Employment Agreement remain in full force and effect.  The Accrued Obligations and the Severance Benefits are in full satisfaction of any severance benefits under the Employment Agreement, the Equity Plan, and of any other compensation arrangements between you and the Company or the CECO Companies. This Separation Agreement may not be altered, modified, waived or amended except by

a written document signed by a duly authorized representative of the Company and you.  Except as otherwise explicitly provided, this Separation Agreement will be interpreted and enforced in accordance with the laws of the state of Texas, and the parties hereto, including their successors and assigns, consent to the jurisdiction of the state and federal courts of Texas.  The headings in this document are for reference only, and shall not in any way affect the meaning or interpretation of this Separation Agreement.
