Dear Maliek,

We are delighted to add your talent and energy to the DLH Executive Leadership Team!

On behalf of DLH Holdings Corp. (“DLH”, or the “Company”), I am pleased to extend to you an offer of employment in the position of Chief Human Resources Officer. Your role reports directly to me as CEO and you will be a Named Executive Officer (NEO) of the company and member of the DLH corporate Executive Leadership Team (ELT).  In this role you will have responsibility, authority, and accountability for managing the Company’s human resources function and developing and implementing the Company’s strategic plans for its workforce, subject to the direction of the CEO.  As discussed, your start date is expected to be November 8, 2021.

Additionally, as an ELT member and NEO, you will participate in periodic Board of Directors (BoD) presentations, Annual Shareholders meetings and other executive engagements. This will include leading the Human Resources team to attract, retain and develop the employees of DLH in pursuit of its corporate objectives, evaluating acquisition candidates, and other high impact decisions. You agree to devote your full business time and best efforts in the performance of your duties for DLH and its subsidiaries. You understand that you will need to undertake regular travel to our executive and operational offices, and such other occasional travel within or outside the United States. All such travel shall be at the sole cost and expense of the Company and shall be in accordance with government Joint Travel Regulations (JTR) and current Company policy, which will include reasonable lodging and food costs incurred by you while traveling.

Cash Compensation.  The Company will pay you an initial salary at the rate of $300,000 per year, less applicable Federal, state, local and elected withholdings, which will be paid in accordance with the Company’s normal payroll procedures. This salary will be subject to adjustment pursuant to the Company’s employee compensation policies and directions from the Management Resources & Compensation Committee of the Board (the “MRC Committee”). During your employment hereunder, the MRC Committee will review your performance and consider adjustments to your compensation as part of its annual merit increase process for the Company’s senior management team.

Guaranteed Bonus. In recognition of your relinquishment of certain incentive opportunities, you will be issued a signing bonus of $75,000 payable at 90 days following your start date.

Incentive Compensation. In addition, you will be eligible to be considered for short term and long term incentive compensation arrangements, subject to the discretion of the MRC Committee. Beginning in fiscal year 2022, you will be eligible for a cash-based incentive bonus for each fiscal year of the Company during your employment. This bonus opportunity will be awarded based on objective and/or subjective criteria established by the MRC Committee, in consultation with me. Subject to the MRC Committee’s approval, you will have an opportunity to earn a cash bonus of up to 50% of your annual base salary based on the Company’s completion of preset goals as will be set forth in an annual management bonus

opportunity plan. In addition, subject to the approval of the MRC Committee, you will be eligible for a grant of performance-based restricted stock units (“Performance RSUs”). It is anticipated that the value of the Performance RSUs will be based on a percentage of your base salary and vest upon the achievement of performance metrics, including revenue and stock price targets, over a multi-year performance period, as determined by the MRC Committee.

Equity Compensation. Subject to MRC Committee approval, you will be granted an option to purchase 250,000 shares of DLH Holdings Corp. Common Stock pursuant to the Company’s 2016 Omnibus Equity

Incentive Plan (the “Plan”) (the “Options”). The exercise price of the Options shall be equal to the fair market value of the Company’s Common Stock on the grant date, as determined in accordance with the Plan. The Options shall be subject to vesting requirements, with 50,000 options vesting on the first anniversary of the grant date and the remainder vesting as follows: (i) 66,667 shares if the closing price of the Company’s Common Stock equals or exceeds a price that is a 50% increase over the exercise price of such Options for ten consecutive trading days; (ii) 66,667 shares if the closing price of the Company’s Common Stock equals or exceeds a price that is a 75% increase over the exercise price for ten consecutive trading days; and (iii) 66,666 shares if the closing price of the Company’s Common Stock equals or exceeds a price that is a 100% increase over the exercise price for ten consecutive trading days. The Options will have a ten (10) year term from their date of grant in which they can be exercised (subject to your continued service and the vesting provisions described above) and will be subject to the terms and conditions of the Plan and option agreement between and the Company in the form approved by the MRC Committee.
