Second Amended and Restated Letter Agreement between the Company and Todd Nelson dated November 16, 2023

Positions and Duties. You will resign as the Executive Chairman of the Company and will serve as the Company’s Chief Executive Officer and President, and shall report directly to the Board of Directors of the Company (the “Board”). You will render such business and professional services in the performance of your duties, consistent with your position in the Company, as are reasonably assigned to you by the Board. The period you are employed by the Company under this Second Amended and Restated Letter Agreement is referred to herein as the “Employment Term.” During the Employment Term, you will devote your full business time and efforts to the Company and will use good faith efforts to discharge your obligations under this Second Amended and Restated Letter Agreement to the best of your ability and in accordance with applicable law and each of the Company’s ethics guidelines, conflict of interest policies and any code of business conduct policies as may be in effect from time to time. During the Employment Term, you agree not to actively engage in any other employment, occupation, or consulting activity for any direct or indirect remuneration without the prior approval of the Board; provided, you may engage in charitable and civic activities and, upon prior approval of the Board, may serve on one for-profit board of directors, provided such activities and service are not competitive with the Company and do not interfere with your duties.

At-will Employment. You and the Company agree that your employment with the Company constitutes “at-will” employment and either you or the Company may terminate your employment at any time for any reason, subject to the terms of this Second Amended and Restated Letter Agreement below. Without limiting the foregoing, you may be entitled to severance and other benefits in connection with termination of your employment depending upon the circumstances of the termination of your employment, as set forth in this Second Amended and Restated Letter Agreement.

Board Membership. You will continue to serve as a member of the Board. Your continued service as a member of the Board will be subject to the Board’s ongoing nomination process and any required stockholder approval. Upon the termination of your employment with the Company for any reason and unless otherwise requested by the Board, you will be deemed to have resigned from the Board (and all other positions held at the Company and its affiliates) voluntarily and without further action from the Board, effective as of the end of your employment, and you, at the Board’s request, will execute the documents necessary to reflect your resignation from the Board.

Base Salary. For the period commencing on and following the Effective Date, you will be paid an annual base salary at the rate of $800,000, payable in installments in accordance with the Company’s standard payroll schedule. Your base salary may be re-determined annually by the Board or the Compensation Committee of the Board (the “Compensation Committee”) from time to time while serving in this role of Chief Executive Officer and President. The annual base salary in effect at any given time is referred to herein as “Base Salary”.

Annual Bonus. You will be eligible to participate in the Company’s Annual Incentive Award Program (or successor program) (“AIP”) and thereby earn an annual target performance bonus equal to 125% of your Base Salary, with a maximum payment level of 200% of your target bonus amount for fiscal year 2023 payable in cash in an amount determined by the Board, or the Compensation Committee, in its sole and absolute discretion, based upon performance criteria determined by the Board or the Compensation Committee (the “Annual Bonus”). For years after 2023, subject to any change that may be implemented by the Compensation Committee and similarly effects all executive officers of the Company, your target bonus opportunity for each year’s Annual Bonus (expressed as a percentage of your Base Salary) will not be less than the target bonus opportunity for fiscal year 2023. The Annual Bonus for each year shall be paid within a reasonable amount of time after the amount of such Annual Bonus is determined by the Compensation Committee for the applicable fiscal year to which the Annual Bonus relates, based on the achievement of the applicable performance conditions. In any event, the Annual Bonus shall be paid no later than March 15th of the calendar year following the end of the Company’s fiscal year to which such bonus relates.

Benefits. During the Employment Term, you will be eligible to participate in the benefit programs generally available to senior executive employees of the Company.

Long-Term Incentive Awards. Following the Effective Date, you may be eligible to receive annual equity awards (each, a “Long-Term Incentive Award”) under the Company’s 2016 Incentive Compensation Plan (as amended and/or restated from time to time, the “2016 Plan”) or such other equity plan as then in effect, in the sole discretion of the Board or the Compensation Committee; provided that, for fiscal year 2024, you will be eligible to receive a Long-Term Incentive Award with a target value of 300% of your Base Salary. For the avoidance of doubt, each of your equity awards outstanding as of the Effective Date will continue to vest following the Effective Date, for so long as you continue to provide services to the Company as an employee of the Company and/or as a member of the Board, subject to the terms of the applicable equity award agreement and equity plan. Upon termination of your employment, (i) the equity awards granted prior to the Effective Date shall cease to vest or be exercisable (as applicable) and, to the extent unvested, shall be cancelled and forfeited, in each case, in accordance with the terms and conditions set forth in the applicable equity award agreement and (ii) unless (x) your employment is terminated by the Company for Cause or (y) you terminate your employment without Good Reason and fail to provide a minimum of six (6) months’ advance written notice of such termination without Good Reason, the Long-Term Incentive Awards granted following the Effective Date shall accelerate (to the extent unvested) and become immediately vested, effective as of the effective date of termination of your employment; provided that, for any Long-Term Incentive Award granted following the Effective Date that is subject to performance-based vesting with a multi-year performance period, if your qualifying termination of employment occurs within the first year of an open performance period, the performance criteria for such award shall be deemed achieved at the “target” level of performance (as set forth in the applicable equity award agreement) and if your qualifying termination of employment occurs following the first year of an open performance period, the performance criteria for such award shall be deemed achieved at the actual level of performance, measured as of the effective date of termination of your employment in substantially the same manner as contemplated by the applicable equity award agreement following the completion of the applicable performance period, as determined by the Board or the Compensation Committee in its sole discretion. For the avoidance of doubt, consistent with Section 21.9 of the 2016 Plan (Employment Agreement Supersedes Award Agreement), in the event of any conflict or inconsistency between the terms of this Second Amended and Restated Letter Agreement and the terms of an applicable equity award agreement for a Long-Term Incentive Award granted following the Effective Date, the terms of this Second Amended and Restated Letter Agreement shall govern.

Reserved.

Severance. To the extent that your employment is terminated (i) by the Company without Cause, (ii) by you for Good Reason (but not for death or Disability) or (iii) by you without Good Reason and with a minimum of six (6) months’ advance written notice of such termination without Good Reason (a “Qualifying Resignation”), you will be eligible to receive benefits under the Company’s Executive Severance Plan (as most recently amended and restated as of November 2, 2015, as amended on July 9, 2020), as such plan may be further amended, restated or replaced from time to time (the “Severance Plan”), subject to satisfaction of the Severance Plan’s relevant requirements (e.g., incurring a qualifying termination, which shall include a Qualifying Resignation, and execution and non-revocation of a release of claims (“Release”)). Notwithstanding the foregoing, for purposes of determining the benefits due to you pursuant to the Severance Plan,

the following shall be deemed to be added to the end of Section I.C of the Severance Plan: “For purposes of this Plan, the Eligible Employee shall be deemed to have been involuntarily terminated by action of the Company if the Eligible Employee terminated his employment with the Company for Good Reason (as defined in Exhibit A to that certain Second Amended and Restated Letter Agreement between the Company and the Eligible Individual dated as of November 16, 2023 (the “Second Amended and Restated Letter Agreement”)) or the Eligible Employee terminated his employment with the Company without Good Reason but has provided a minimum of six (6) months’ advance written notice of such termination without Good Reason to the Company;”

the definition of “Pay” in Section II.A.1 of the Severance Plan, shall be deemed to be “the sum of (a) two (2) times his or her annual base salary as shown on the Company’s records at the time of termination, and (b) two (2) times the target value of his or her annual incentive under the Company’s applicable annual incentive program (or program of similar effect) for the year in which termination occurs;” and

a new Section II.A.4 shall be deemed to have been added to the Severance Plan, which Section II.A.4 shall be deemed to read as follows: “Prorated Bonus. Subject to compliance with Plan requirements, an Eligible Employee shall receive payment of a pro rata portion of his Annual Bonus (as defined in the Second Amended and Restated Letter Agreement) for the fiscal year of the Company in which his termination occurs, based on the number of days of such fiscal year that elapsed through the date his employment terminated and calculated based on the actual performance results applicable to such fiscal year (with any exercise of negative discretion to be based only on achievement (or lack thereof) of previously-established performance goals and not subjective personal performance), payable at such time as bonuses are paid by the Company to senior executives pursuant to the terms of the AIP (as defined in the Second Amended and Restated Letter Agreement), but in no event will such amount be paid after March 15th of the calendar year following the end of the fiscal year to which the Annual Bonus relates.”

Golden Parachute Excise Tax. If the payments and benefits provided for in this Second Amended and Restated Letter Agreement or otherwise payable to you from the Company constitute “parachute payments” within the meaning of Section 280G of the Internal Revenue Code of 1986, as amended (the “Code”), and would be subject to the excise tax imposed by Section 4999 of the Code, then such payments and benefits shall be subject to reduction to the extent necessary to assure that the payments and benefits provided to you under this Second Amended and Restated Letter Agreement will be limited to the greater of (a) the amount of payments and benefits that can be provided without triggering a parachute payment under Section 280G of the Code or (b) the maximum dollar amount of payments and benefits that can be provided so as to provide you with the greatest after-tax amount of such payments and benefits after taking into account any excise tax you may incur under Section 4999 of the Code with respect to those payments and benefits and any other benefits or payments to which you may be entitled in connection with any change in control or ownership of the Company under Section 280G of the Code or the subsequent termination of your employment. To the extent reduction of any payments and benefits is required by this Section 10 such that no portion of your severance benefits will be subject to the excise tax imposed by Section 4999 of the Code, the severance benefits shall be reduced in the following order: (i) cash severance pay, (ii) cash payments based on the awards granted pursuant to the 2016 Plan and Section 7 of this Second Amended and Restated Letter Agreement, and (iii) any equity awards granted to you.

Indemnification. You will continue to be party to the Company’s current form of Indemnification Agreement applicable to executive officers and members of the Board and you will be covered as an insured (including coverage after a termination of your employment and service as a director respecting your acts and omissions occurring during your employment or as a director) under any contract of directors and officers liability insurance that covers directors as insureds.

Subject to the foregoing, in the event any payment or benefit becomes due under Section 9 conditioned upon your entering into a Release, and as a result of the date of such Release the payment or benefit could be made in either of two of your taxable years, such payment or benefit shall be made on the later of January 15 of the later such taxable year or within ten (10) days after the date such Release becomes effective. No reimbursement payable to you pursuant to any provision of this Second Amended and Restated Letter Agreement or otherwise pursuant to any plan or arrangement of the of the Company shall be paid later than the last day of the calendar year following the calendar year in which the related expense was incurred, and no such reimbursement during any calendar year shall affect the amounts eligible for reimbursement in any other calendar year, except, in each case, to the extent that the right to reimbursement does not provide for a “deferral of compensation” within the meaning of Section 409A of the Code. In addition, your right to reimbursement (or in-kind benefits) cannot be liquidated or exchanged for any other benefit or payment. Each separately identifiable payment or installment payment hereunder shall be deemed a “separate payment” for purposes of Section 409A of the Code.

You further acknowledge that the Company and/or the Company Affiliates provide career-oriented education through physical campuses throughout the United States and web-based virtual campuses throughout the world and, therefore, it is impracticable to identify a limited, specific geographical scope for this Section 16(e). Nothing herein shall prevent you from owning less than 2% of the capital stock of a company whose stock is publicly traded and that is engaged in Competing Educational Services.

You acknowledge and agree that the Company will suffer irreparable injury in the event of a breach by you of the terms of this Section 16. In the event of a breach of the terms of this Section 16, the Company shall be entitled, in addition to any other remedies and damages available and without proof of monetary or immediate damage, to a temporary and/or permanent injunction, without bond, to restrain the violation of this Section 16 by you or any persons acting for or in concert with you. Such remedy, however, shall be cumulative and nonexclusive and shall be in addition to any other remedy that the parties may have.

To the extent inconsistent, the provisions of this Section 16 will control over any restrictive covenant provided in any other agreement (including the duration of any covenant following termination of employment), including any award agreement granted under the Plan, entered into from time to time unless such other agreement specifically provides that it controls over this Section 16.

The provisions of this Section 16 shall be deemed severable and the invalidity or unenforceability of any provision shall not affect the validity or enforceability of the other provisions hereof. If any provision in this Section 16 is found by a court of competent jurisdiction to be unenforceable or unreasonable as written, you and the Company hereby specifically and irrevocably authorize and request said court to revise the unenforceable or unreasonable provisions in a manner that shall result in the provision being enforceable while remaining as similar as legally possible to the purpose and intent of the original.

Arbitration.

Arbitrable Claims. You and the Company mutually consent to the resolution by final and binding arbitration of any and all disputes, controversies or claims related in any way to your employment with the Company, including, but not limited to, any dispute, controversy or claim of alleged discrimination, harassment or retaliation (including, but not limited to, claims based on race, sex, sexual orientation, gender identity, gender expression, religion, national origin, age, marital or family status, medical condition, military status, handicap or disability, or any other legally-protected status), any claim arising out of or relating to this Second Amended and Restated Letter Agreement, any awards granted hereunder, or the breach thereof, and any dispute as to the arbitrability of a matter under this provision (collectively, “Claims”); provided, however, that nothing herein shall require arbitration of any claim or charge which, by law, cannot be the subject of a compulsory arbitration agreement. You and the Company expressly acknowledge that you waive the right to litigate Claims in a judicial forum before a judge or jury.

Claim Initiation/Time Limits. A party must notify the other party in writing of a request to arbitrate Claims within the same statute of limitations applicable to the legal claim asserted. The written request for arbitration must specify: (i) the factual basis on which the Claims are made; (ii) the statutory provision or legal theory under which Claims are made; and (iii) the nature and extent of any relief or remedy sought.

Procedures. The arbitration will be administered in Chicago, Illinois, in accordance with the Employment Arbitration Rules and Mediation Procedures then in effect (“Rules”) of the American Arbitration Association (“AAA”), a copy of which is available upon request to the Company. The arbitration shall be conducted by a tribunal of three arbitrators, of whom you shall appoint one and the Company shall appoint one. The two arbitrators so appointed shall select the chairman of the tribunal within thirty (30) days of the appointment of the second arbitrator. If any arbitrator is not appointed within the time limits provided herein or in the Rules, such arbitrator shall be appointed by the American Arbitration Association. You and the Company may be represented by counsel of your choosing. You and the Company shall pay your own legal fees (including counsel fees), and other fees and expenses incurred by you in obtaining or defending any right or benefit under such Claims; provided, however, that, irrespective of the outcome of any arbitration under this Section 17, the Company will pay any fees of the AAA, filing costs, arbitrator fees or expenses and any reasonable travel expenses incurred by you in connection with your travel to Chicago, Illinois for any arbitration proceeding.

Responsibilities of Tribunal; Award; Judgment. The tribunal will act as the impartial decision maker of any Claims that come within the scope of this arbitration provision. The tribunal will have the powers and authorities provided by the Rules and the state or common law under which the claim is made. For example, the tribunal will have the power and authority to include all remedies in the award available under the statute or common law under which the claim is made including, without limitation, the issuance of an injunction. The tribunal will apply the elements and burdens of proof, mitigation duty, interim earnings offsets and other legal rules or requirements under the statutory provision or common law under which such claim is made. The tribunal will permit reasonable pre-hearing discovery. The tribunal will have the power to issue subpoenas. The tribunal will have the authority to issue a summary disposition if there are no material factual issues in dispute requiring a hearing and you or the Company is clearly entitled to an award in its or your favor. The tribunal will not have the power or authority to add to, detract from or modify any provision of this Second Amended and Restated Letter Agreement, or any related agreements or plans, including but not limited to any equity awards. The tribunal, in rendering an award in any arbitration conducted pursuant to this provision, shall issue a reasoned award in a signed written opinion stating the findings of fact and conclusions of law on which it is based. The tribunal shall be required to follow the law of the state designated by the parties herein. Any judgment on or enforcement of any award, including an award providing for interim or permanent injunctive relief, rendered by the tribunal may be entered, enforced or appealed in any court having jurisdiction thereof. Any arbitration proceedings, decision or award rendered hereunder, and the validity, effect and interpretation of this arbitration provision, shall be governed by the Federal Arbitration Act, 9 U.S.C. § 1 et seq.

No other agreement relating to the terms of your employment by the Company, oral or otherwise, shall be binding between the parties unless it is in writing and signed by the party against whom enforcement is sought.
