Dear ▇▇▇▇▇:

This Separation Agreement (the “Agreement”) will confirm our mutual understanding and agreements regarding your separation, individually and collectively, from Covanta Projects, LLC (“Employer”), Covanta Energy LLC and its subsidiaries (“Covanta Energy”) and Covanta Holding Corporation (“Parent”). For purposes of this Agreement, Employer, together with Parent and its direct and indirect subsidiaries, including without limitation, Covanta Energy, are referred to herein collectively as the “Covanta Companies.” Unless otherwise defined herein, capitalized terms shall have the meaning ascribed to them in the Severance Plan for Covanta Energy LLC Senior Officers effective as of February 25, 2010 (the “Severance Plan”).

In order to effectuate a smooth transition and separation of your employment by the Employer, for good and valuable consideration, the sufficiency of which is hereby agreed to and acknowledged, you, Employer, Covanta Energy and Parent hereby agree as follows:

1.Termination of Employment and Board Membership. Pursuant to the mutual agreement of you and the Covanta Companies, effective as of October 29, 2020, you resigned from your office as President and Chief Executive Officer (“Effective Date”) and your employment by the Covanta Companies shall be deemed to be terminated effective as of November 28, 2020 (the “Termination Date”). As of the Effective Date, (i) your resignation as a member of the Board of Directors of Parent was accepted; and (ii) you ceased to hold any positions as an officer with any of the Covanta Companies, including without limitation, Parent, or as a director, member or manager of any of Covanta Companies.

2.Final Compensation. As soon as administratively practicable after the Termination Date, as required by applicable law, Employer shall pay you all accrued but unpaid wages, any earned but unused vacation days, subject to standard payroll deductions and withholdings, and any previously unreimbursed business expenses incurred on behalf of the Covanta Companies, subject to the presentation of documentation therefor in accordance with Covanta Energy’s regular reimbursement procedures and practices. Any personal advances due

to outstanding business-related expenses will be deducted from the cash amounts otherwise due to you hereunder. For the avoidance of doubt, such final compensation payments shall be equal to the following:

(a)Unpaid wages for the pay period beginning on November 21, 2020 and ending on November 28, 2020 in the amount of $17,307.70; and

(b)Accrued and unused paid time off of 206.7 hours (40 hours carryover from 2019 and 166.7 hours unused for 2020), and equivalent to $89,437.49.

3.Full Payment. You hereby acknowledge that the payments and arrangements set forth in this Agreement constitute full and complete satisfaction of any and all amounts properly due and owing to you as a result of your employment with Employer and the termination thereof.

4.Severance Payments.

(a)Following the termination of your employment by the Covanta Companies, you shall be entitled to receive salary continuation payments, based upon your annual salary of $900,000 as of the Termination Date, for a period of twenty-four (24) months, payable in cash in bi-weekly installments (each such installment, a “Severance Payment”) pursuant to and subject to the conditions set forth in the Severance Plan (as modified by this Agreement to comply with Section 409A of the Internal Revenue Code (“Section 409A”) and subject to your performance of your obligations pursuant to this Agreement, including, without limitation, under Section 12; provided, however, that such Severance Payments will not commence until after the expiration of the Revocation Period (as defined below) (with the first payment to include a catch-up for amounts that would have been payable during the Revocation Period had Severance Payments started on the first payroll date following the Termination Date). Notwithstanding the foregoing, if any of the Severance Payments are treated as “non-qualified deferred compensation” under Section 409A, then if such Severance Payments could commence in more than one taxable year depending on when the Release (as defined below) is executed (regardless of when the Release is actually executed), then such payments and benefits that otherwise would have been payable in the calendar year in which the Termination Date occurs shall be withheld and shall instead be payable on the first payroll date in the calendar year immediately following the calendar year in which the Termination Date occurs (with all remaining payments to be made as if no such delay had occurred).

(b)The Compensation Committee of the Board of Directors of Parent (the “Compensation Committee”) shall award you a non-equity incentive bonus for your performance in 2020 on a non pro-rated basis, payable in a lump sum cash payment on or before March 15, 2021. The non-equity incentive bonus for your performance in 2020 awarded pursuant to this Section 4(b) shall be equal to the general corporate multiplier approved by the Compensation Committee for 2020, multiplied by 120% of your annual base salary in 2020 of $900,000.

(c)If you recommence work with any of the Covanta Companies as an employee before all Severance Payments have been made to you or materially breach any of

your obligations under this Agreement, such payments will stop as of the effective date of commencement of such work.

(d)While you may not be precluded from applying for and receiving unemployment compensation benefits, if you do receive any such benefits for the same weeks for which you are receiving Severance Payments, any amounts you receive in unemployment compensation will be deducted from the Severance Payments made to you for those weeks. In addition, the following will be deducted from your Severance Payments if received for the same weeks you are receiving Severance Payments: short-term disability (STD) and worker’s compensation benefits.

5.Benefits.

(a)Covanta Energy shall provide you with the opportunity to continue group medical and dental insurance coverage equivalent to that provided to senior officers of Covanta Energy for a period of twenty-four (24) months following the Termination Date (the “Severance Period”), pursuant to the terms of this Section 5(a). You and your dependents may make a timely election, effective as of the day after the Termination Date, to continue your group medical and dental coverage under Code Section 4980B (“COBRA”). If such a timely COBRA election is made, you shall be entitled to all medical (including prescription and vision) and dental benefits under Covanta Energy’s benefit plans as if you were still employed during such period, at the same level of benefits and at the same dollar cost to you as if you had remained an active employee if and only to the extent permitted under such plans. Covanta Energy will deduct from each Severance Payments an amount equal to the bi-weekly premium payable by similarly situated senior officers for such medical and dental coverage, to the extent you and your dependents remain eligible for COBRA continuation coverage. Any taxes required to be withheld for the portion of the bi-weekly premium for such COBRA continuation coverage that is payable by Covanta Energy will be withheld from the Severance Payments. Covanta Energy’s payment of its share of the COBRA premiums described in this Section 5(a) is subject to the performance of your obligations pursuant to this Agreement, including, without limitation, pursuant to Section 12.

(b)To the extent permitted under any of the Covanta Companies’ benefit plans, Employer shall continue to provide and you shall continue to participate in any group accident insurance, short-term disability insurance, life insurance or long-term disability insurance coverage for a period of 24 months following the Termination Date. Immediately thereafter, any group accident insurance, short-term disability insurance, life insurance or long-term disability insurance coverage you have with the Covanta Companies will terminate. To the extent such continuation of coverage is not permissible under any such benefit plan, your coverage under such plan will terminate as of the Termination Date and Employer shall pay to you an amount each month for a period of 24 months thereafter equal to the premium under such plan that Employer paid on your behalf for coverage under such plan immediately prior to the Termination Date (or $27.00 per month under the group accident insurance plan, $64.00 per month under the group life insurance plan and $103.00 per month under the group long-term

disability plan), which Employer shall pay coincident with any payments you are scheduled to receive pursuant to Section 4(a).

(c)Notwithstanding anything to the contrary in Section 5(a), in the event that you receive or obtain benefits of the type described in Section 5(a) from another employer, then the Covanta Companies obligation to provide such benefits under this Agreement or the Severance Plan shall terminate. You hereby covenant and agree to promptly inform and notify the Covanta Companies in writing of your right to receive or obtain benefits of the type described in Section 5(a).

All amounts allocated to such account are subject to the vesting and other terms of the 401(k) Plan, which shall not be deemed to have been modified by this Agreement. You may receive a distribution of your account balance in the 401(k) Plan following the Termination Date. Information about your account balance will be sent to you by ▇. ▇▇▇▇ Price, or you may contact them at (▇▇▇) ▇▇▇-▇▇▇▇.

EXHIBIT A

EMPLOYEE CONFIDENTIAL DISCLOSURE AGREEMENT

In connection with the scope of my employment with Covanta Holding Corporation (“Covanta”) or an affiliate thereof, I acknowledge that certain information deemed by Covanta to be confidential or proprietary in nature, including trade secrets (collectively, the "Confidential Information"), of Covanta and its subsidiaries and affiliates (collectively, the "Covanta Affiliates") will be disclosed directly or indirectly to me. Such Confidential Information allows Covanta Affiliates to compete advantageously for business and to perform their duties and obligations on favorable terms and includes, but is not limited to, (a) financial information and performance information, however measured, of Covanta Affiliates of their respective assets, (b) information concerning facilities designed, constructed or operated by Covanta Affiliates, as well as processes, product equipment or apparatus embodied in such facilities or used in the design or construction thereof, (c) estimating, pricing and bidding practices and customer contracts of Covanta Affiliates, (d) the particular qualifications and methods of organization of the personnel of Covanta Affiliates, (e) projects, and particularly problems and resolutions encountered in such projects, in which Covanta Affiliates have worked or bid, (f) marketing plans and/or strategic plans of Covanta Affiliates, (g) information, of any type, of others as to which Covanta Affiliates have an obligation of confidential treatment, (h) customers, suppliers, partners and potential partners of Covanta Affiliates and (i) any other information maintained in trust and confidence by Covanta Affiliates, the knowledge of which by any person, firm, corporation or other business entity not affiliated with Covanta Affiliates may detrimentally affect any Covanta Affiliate. In consideration of, and as a condition to, my continued employment with Covanta, I agree to strictly adhere to the obligations set forth below:

1. I will not, at any time during, or during the five (5) years following termination of, my employment, without the written consent of Covanta publish, make available or disclose to any person, firm, corporation or other entity (other than Covanta Affiliates) any Confidential Information, nor will I duplicate or use, directly or indirectly, the Confidential Information for purposes other than the business purposes of Covanta Affiliates.

2. I agree that all Confidential Information, including drawings, specifications, sketches, blueprints, reports, memoranda, computer printouts and other documents, whether in printed, graphic, film, tape, disc or other recorded form, delivered to me, acquired by me or developed by me, and arising out of my employment shall be the sole and exclusive property of Covanta, regardless of whether such items contain or constitute Confidential Information. Upon termination of my employment for any reason whatsoever, whether by Covanta or by me, I will deliver to Covanta immediately all copies of such documents

and I shall not retain copies or excerpts of any such documents whether prepared by me or delivered to me or made available to me during the course of my employment. I shall not use any such documents for purposes other than the business purposes of Covanta Affiliates.

3. I agree that no right or license is granted to me by Covanta to use the Confidential Information.

4. I agree to notify Covanta promptly of any developments or inventions relating to the business interests of Covanta Affiliates and, without limitation, any developments or inventions arising out of, or in connection with, the Confidential Information. I agree that any developments or inventions created by me during the course of my employment by Covanta shall be the sole and exclusive property of Covanta and I further agree to execute, or cause to be executed, any and all patent applications, assignments or other instruments reasonably required by Covanta to transfer, vest and retain in Covanta title and exclusive right to any and all such inventions and developments without any further consideration to be imparted to me by Covanta. It is understood that Covanta shall have full right to exercise its discretion in deciding whether such developments or inventions shall be patented. It is further understood that Covanta shall bear all costs and fees in connection with the protection of such developments or inventions.

5. For purposes of this Agreement, Confidential Information does not include information that:

(a) at the time of disclosure to me is in the public domain or public knowledge;

(b) after disclosure to me becomes part of the public domain or public knowledge by publication or otherwise, except by breach of this Agreement by me;

(c) I can establish by competent written proof was in my possession at the time of disclosure to me and was not acquired, directly or indirectly, from Covanta Affiliates; or

(d) I lawfully receive from any person, firm, corporation or other entity (other than Covanta Affiliates), provided, however, that such information was not obtained by such person, firm, corporation or entity directly or indirectly from any Covanta Affiliate or any predecessor licensee of the ▇▇▇▇▇▇ technology pursuant to a Confidential Disclosure Agreement or unlawfully.

6. My obligations under this Agreement will continue for a period of five (5) years from termination of my services for Covanta.
