Consulting Services Agreement

This Consulting Services Agreement (“Agreement”) is made between Maximus, Inc., a Virginia corporation (“Maximus”), and Richard J. Nadeau (“Consultant”), with reference to the following:

WHEREAS, Maximus seeks consulting services related to the transition of the Chief Financial Officer position, transition of the principal accounting officer role and continued support for investor relations and communications; and

WHEREAS, Consultant is willing and able to perform the services described herein in accordance with the terms of this Agreement;

NOW, THEREFORE, in consideration of the mutual terms, conditions and covenants set forth herein, the parties agree as follows:

1.    Consultant’s Services. Consultant agrees to render services to Maximus in accordance with the Statement of Work (SOW) attached hereto as Exhibit 1 and incorporated by reference. Consultant shall work under the direction of Bruce Caswell or his designee. Additional services not specifically described in the SOW will be performed by Consultant pursuant to a Task Order executed by authorized representatives of the parties in advance of the commencement of those additional services and subject to the terms and conditions of this Agreement.

a. Compensation. In consideration of those services, Maximus shall pay Consultant a retainer of $11,000 per month.

b. Reimbursable Expenses. In addition to the fee specified in subparagraph (a), Maximus shall reimburse Consultant for reasonable, necessary and substantiated expenses incurred by Consultant for out-of-town travel, lodging, meals, automobile rental and administrative expenses in connection with the services rendered hereunder; provided, however, that any such expenses must comply with the Maximus travel and expense reimbursement policies. Consultant will continue to have use of his Maximus-issued company cellular phone for the term of the Agreement.

c. Manner of Payment. Once each month, Consultant shall prepare and submit to Maximus an invoice, by the tenth (10th) day of each month, referencing services rendered in accordance with this Agreement and expenses incurred during the preceding month, together with such supporting documentation as may be required by Maximus. Maximus shall pay Consultant within thirty (30) days after receipt and approval of the invoice and any required supporting documentation.

3.    Status as Independent Contractors. This Agreement shall not constitute or otherwise imply an employment, joint venture, partnership, agency or similar arrangement, and nothing contained herein shall be construed as providing for the sharing of profits or losses arising from the efforts of either or both of the parties hereto. Each party to this Agreement shall act as an independent contractor, and neither party shall have the power to act for or bind the other party except as expressly provided for herein. Consultant assumes sole responsibility for determining the manner and means of performance hereunder. Consultant shall not be eligible for any

benefit available to employees of Maximus, including, but not limited to, workers compensation insurance, state disability insurance, unemployment insurance, group health and life insurance, vacation pay, sick pay, severance pay, bonus plans, pension plans, savings plans and the like. No income, social security, state disability or other federal or state payroll tax will be deducted from payments made to Consultant under this Agreement. Consultant agrees to pay all state and federal taxes and other levies and charges as they become due on account of monies paid to Consultant hereunder, and to defend, indemnify and hold MAXIMUS harmless from and against any and all liability resulting from any failure to do so.

4.    Term. This Agreement shall be effective as of December 1, 2021 (“Effective Date”) and shall continue in effect until May 31, 2022 unless terminated sooner as provided in Section 5 below. Upon mutual agreement of the parties, the Agreement may be extended an additional six (6) months to November 30, 2022 at the monthly retainer specified in Section 2 above. If the parties agree to not extend the Agreement for such additional term, Maximus will pay Consultant a one-time fee of $33,000 representing 50% of the monthly retainer for the unexercised six-month extension period.

5.    Termination. Either party shall have the right to terminate this Agreement if the other party is in default of any obligation hereunder and such default is not cured within ten (10) days of receipt of a notice from the non-defaulting party specifying such default. This Agreement may also be terminated by Maximus immediately and without prior notice if (a) Consultant has violated any state or federal law, (b) Consultant has made a material misrepresentation or (c) Consultant breaches a confidentiality obligation. Maximus shall compensate Consultant for work satisfactorily performed up to the effective date of the termination less any amounts that are the subject of a good faith dispute.

6.    Termination of Services and Return of Maximus Property. Upon the expiration or earlier termination of this Agreement, Consultant shall immediately terminate the services hereunder, and shall deliver promptly to Maximus all property relating to the business, work and investigations of Maximus, and to any Work Product (as defined below), patents or copyrights covered by this Agreement. Such property shall include but not be limited to all hardware and software, written, graphical, and recorded material, and any copies, abstracts or summaries thereof.

7.    Changes. Maximus may, at any time by written order, make changes in the Consultant’s work within the general scope of the Statement of Work. If any change under this section causes an increase or decrease in the Consultant’s cost of, or time required for, the performance of any part of the work, the parties shall negotiate an equitable adjustment to the compensation payable hereunder, and this Agreement shall be modified in writing accordingly. Should Consultant be required to devote more than ten (10) hours per week to the services described herein, the parties will negotiate an equitable adjustment to the compensation provided in Section 2.

8.    Standard of Performance. Consultant warrants and represents that he possesses the special skill and professional competence, expertise and experience to undertake the obligations imposed by this Agreement. Consultant agrees to perform in a diligent, efficient, competent and skillful manner commensurate with the highest standards of the profession, and to devote such time as is necessary to perform the services required under this Agreement.

9.    Conflicts of Interest. Consultant warrants and represents that (i) the work hereunder will not create an actual or apparent conflict of interest with any other work he might perform, (ii) Consultant is not presently subject to any agreement with a competitor or potential competitor of

Maximus or with any other party that will prevent Consultant from performing in full accord with this Agreement and (iii) Consultant is not subject to any statute, regulation, ordinance or rule that will limit his ability to perform the obligations under this Agreement. The parties agree that Consultant shall be free to accept other work during the term hereof; provided, however, that such other work shall not interfere with the provision of services hereunder, and further provided that, without the prior consent of Maximus, Consultant shall not accept other work with any competitor of Maximus that creates a conflict of interest with Maximus. The parties acknowledge that Consultant has entered into a Separation Agreement with Maximus that governs Consultant’s post-employment activities. In the event of any inconsistency between this Agreement and the Separation Agreement, the terms of the Separation Agreement shall control.

10.    Confidential Information. Consultant acknowledges that he may have access to and become acquainted with (i) confidential and other information proprietary to Maximus including, but not limited to, information concerning MAXIMUS, its operations, customers, business and financial condition, proprietary software and materials and, (ii) information with respect to which MAXIMUS has an obligation to maintain confidentiality including, but not limited to, Protected Health Information (PHI) protected pursuant to the Health Insurance Portability and Accountability Act of 1996, Pub. L. No. 104-191 (“HIPAA”), as amended by the Health Information Technology for Economic and Clinical Health (“HITECH”) Act (Division A, Title XIII and Division B, Title IV of Public L. 111–5) (collectively referred to herein as "Confidential Information").

The Consultant also agrees not to use or disclose any Confidential Information in violation of securities or insider trading laws.

11.    Work Product. Consultant agrees that all work product, inventions, discoveries, ideas, concepts, designs, specifications, reports, data, software, information systems, processes, methods, formulas and techniques, as well as improvements thereof or know-how related thereto (collectively “Work Product”), which are created by Consultant in the performance of this Agreement shall be the sole property of Maximus. Consultant agrees that all such Work Product shall from inception be considered “works made for hire” and shall be the exclusive property of Maximus or its designee, and Consultant hereby expressly waives any right or interest he may have therein. Consultant agrees to provide, without additional compensation, such assistance as may reasonably be required by Maximus in obtaining patents and copyrights for such Work Product in any and all countries, and in enforcing any Maximus rights and interests relating to such Work Product or to any patents or copyrights resulting therefrom, including without limitation the execution by Consultant of all applications, assignments and other instruments as Maximus may request. Consultant’s pre-existing intellectual property shall remain the property of Consultant; provided, however, that to the extent the Consultant incorporates such intellectual property into any materials delivered to Maximus hereunder, Consultant hereby grants to MAXIMUS a royalty-free, non-exclusive license to use such intellectual property to carry out the purposes of this Agreement and any obligations Maximus has to its clients.

Consultant warrants and represents that all of the Work Product, findings and recommendations disclosed to Maximus during the course of this Agreement may lawfully be disclosed by Consultant and are not subject to any patent, license agreement, confidentiality agreement, trade secret law or any other restriction on use by or disclosure to Maximus.

12.    Indemnification. Consultant agrees to defend, indemnify and hold Maximus harmless from and against any and all claims, losses, liabilities or expenses (including without limitation attorneys' fees) which may arise, in whole or in part, out of (i) the gross negligence or willful misconduct of the Consultant, his employees or agents, (ii) a breach by the Consultant of his obligations under this Agreement, or (iii) a claim that any Work Product or other item furnished by Consultant hereunder infringes any third party’s patent, copyright or other intellectual property rights. The indemnity required herein shall not be limited by reason of the specification of any particular insurance coverage. Consultant represents and warrants that he is the owner of any goods or services provided under this Agreement or otherwise has the right to provide such goods or services for the purposes of this Agreement. Consultant shall be covered by the Maximus directors and officers insurance policies for periods prior to December 1, 2021. During the term of this Agreement, Maximus shall indemnify the Consultant on the same terms as applicable to Maximus’ officers and directors.

13.    Insurance. Consultant shall be solely responsible for obtaining workers compensation insurance for his employees, if any, and such other insurance as may be required by applicable laws.

THE TOTAL LIABILITY OF EITHER PARTY HEREUNDER FOR ANY AND ALL DAMAGES WHATSOEVER ARISING OUT OF OR IN ANY WAY RELATED TO THIS AGREEMENT FROM ANY CAUSE, INCLUDING BUT NOT LIMITED TO NEGLIGENCE, ERRORS, OMISSIONS, STRICT LIABILITY, BREACH OF CONTRACT OR BREACH OF WARRANTY SHALL NOT, IN THE AGGREGATE, EXCEED FEES PAYABLE TO CONSULTANT DURING THE TERM HEREOF. IN NO EVENT SHALL EITHER PARTY BE LIABLE FOR SPECIAL, INDIRECT, INCIDENTAL, ECONOMIC, CONSEQUENTIAL OR PUNITIVE DAMAGES, INCLUDING BUT NOT LIMITED TO LOST REVENUE, LOST PROFITS, REPLACEMENT GOODS, LOSS OF TECHNOLOGY RIGHTS OR SERVICES, LOSS OF DATA, OR INTERRUPTION OR LOSS OF USE OF SOFTWARE OR ANY PORTION THEREOF REGARDLESS OF THE LEGAL THEORY UNDER WHICH SUCH DAMAGES ARE SOUGHT EVEN IF THE PARTY HAS BEEN ADVISED OF THE LIKELIHOOD OF SUCH DAMAGES, AND NOTWITHSTANDING ANY FAILURE OF ESSENTIAL PURPOSE OF ANY LIMITED REMEDY.

In the event this Agreement provides for any contingency fees or other such payments to Consultant, Consultant represents and warrants that he is not subject to any statute, regulation, ordinance or rule that would limit or prohibit such payment. In the event such contingency payment is restricted, the parties agree to renegotiate the terms of this Agreement to cause it to be compliant with all applicable laws or, failing to agree on mutually acceptable terms, to terminate this Agreement.
