EMPLOYMENT AGREEMENT
This Employment Agreement (this “Agreement”) is effective as of January 2, 2026, between Aon Corporation (the “Company”), and Andy Marcell (the “Executive”); each referred to as a “Party”, and both referred to collectively as the “Parties.”
WHEREAS, the Executive currently is CEO of Global Solutions, and an at-will employee.
WHEREAS, the Company desires to continue to employ the Executive, and the Executive is willing to continue to be so employed;
WHEREAS, the Company and the Executive previously entered into a Letter Agreement confirming certain terms and conditions of employment dated as of August 3, 2015 (the “Prior Agreement”);
WHEREAS, upon execution of this Agreement by the Company and the Executive, the Prior Agreements and any other employment agreement between Executive and the Company (including its affiliates), shall be superseded in their entirety and shall have no further force or effect (except as otherwise explicitly set forth herein);
WHEREAS, the Executive remains an eligible executive under the Aon plc Amended and Restated Senior Executive Combined Severance and Change in Control Plan (the “SE Plan”) and benefits thereunder; and

NOW, THEREFORE, in consideration of the premises and the mutual agreements contained herein, the parties hereby agree as follows:
1.Employment Term and Renewal. The Company will continue to employ the Executive, and the Executive will continue to be employed, upon the terms and subject to the conditions contained in this Agreement. The term of employment of the Executive pursuant to this Agreement (the “Employment Period”) shall commence effective as of January 1, 2026 (the “Effective Date”) and shall end on December 31, 2030, unless earlier terminated pursuant to Section 4 hereof or extended pursuant to this Agreement. This Agreement may be renewed by mutual written agreement of the parties hereto. If it is not so renewed, and the Executive and the Executive’s employment with the Company continues following the expiration of the Employment Period, such employment shall be on an at-will basis. For the avoidance of doubt, the expiration of the Agreement is not a Qualifying Termination under the Company’s SE Plan.
a.Notice of Termination.
i.Either Party may notify the other that Executive’s employment will be terminated upon the expiration of the Employment Period at any point prior to the expiration of the Employment Period. Each Party agrees to provide a minimum of (1) three hundred and sixty-five (365) days’ advanced written notice, if notice is given between January 1, 2026 and December, 31, 2027 (“First Notice”) and/or (2) seven hundred and thirty (730) days’ advance written notice if notice is given between January 1, 2028 and December 31, 2030 (“Second Notice”) of such intent to terminate his employment (collectively, the “Notice Periods”). At any point after January 1, 2028 where Executive provides Second Notice, the Employment Period shall automatically be extended for the full duration of the applicable Notice Period. During the Notice Period, the Executive shall remain employed by the Company and shall continue to be entitled to all compensation, benefits, and other rights provided under this Agreement as if the Employment Period had not expired, subject to the terms and conditions herein. Second Notice may be given up to and including on December 31, 2030.

In the event that the Executive has not provided advance notice as described above prior to the expiration of the Employment Period, the Executive shall be converted to an at-will employee upon the end of the Employment Period. During the Noncompetition Period (defined below), the Executive will provide any prospective employer the Executive is considering an offer from with notice of the obligations set forth in Sections 7 and 8 of this Agreement at least ten (10) days before accepting such offer.
ii.Company will have the right to place the Executive on administrative leave subject to specific guidelines (a “Garden Leave”) during the Notice Periods. This right will also apply if the Executive provides advance notice of intent not to renew the term of this Agreement. The Executive will remain an employee of the Company during the Garden Leave with continued Base Salary, Annual Bonus, and benefits during the Garden Leave period. Annual Bonus will be calculated based on 100% funding of target annual incentive for the entirety of the applicable Notice period (i.e., for the term of the First Notice or the Second Notice). The Company’s guidelines for the Garden Leave may include, among other things, modifications, restrictions, or limitations on permitted contact with the workplace, facilities, equipment, computer systems, colleagues, clients, suppliers, distributors, and other business relationships that relate to the operation of the Company’s business. The Executive will not undertake employment with any other employer (as an employee, consultant, or otherwise) during the Garden Leave period without written authorization of the Company, and will remain available to perform work for the Company during the Garden Leave period and will perform such Transition Duties as are reasonable and necessary for the retention of business for the Company such as but not limited to transitioning (i) job duties and responsibilities to individual designated by the Company; (ii) client relationships to the Company designated colleague; and (iii) such additional tasks and responsibilities as may be requested from time to time by the Company’s Chief Executive Officer (“CEO”) for purposes of transition responsibilities and/or business relationships related to Executive’s position.
iii.In the event that the Executive fails to comply with the requirements of Sections 1(a)(i) or (ii), the Company shall be entitled to seek an injunction or injunctions to prevent any breach or threatened breach of any of such provisions and to enforce such provisions specifically (without posting a bond or other security). The equitable relief shall be in addition to, not in lieu of, legal remedies, monetary damages or other available forms of relief, including, without limitation, any and all damages (direct and consequential) caused by, or with respect to which the Executive’s breach was a contributing cause, including costs related to expenses incurred in filling the Executive’s position (such as, but not limited to, any recruiting or executive search firm fees) and losses resulting from the loss of customers or other business relationships that the Executive fails to use reasonable efforts to help the Company retain in accordance with this Section 1(a).
iv.Any and all time Executive remains employed or on Garden Leave following delivery of Second Notice shall be credited on a day-for-day basis against Noncompete Period set forth in Section 7 of this Agreement.
2. Duties and Responsibilities. During the Employment Period, the Executive shall perform such executive duties consistent with the position of CEO of Global Solutions on behalf of the Company and its affiliates as may from time to time be authorized or directed by the Company’s CEO, all of which shall be consistent with his current duties and responsibilities. The Executive shall report directly to the CEO and will be a member of the most senior leadership team of the Company. The Executive shall perform faithfully and loyally and to the best of Executive’s abilities the duties assigned to Executive hereunder and shall devote Executive’s full business time, attention and effort to the affairs

4



vesting of all Long-Term Incentive Awards that have been granted to Executive prior to Executive’s date of death, to the extent that such payment or vesting is provided for in the terms of the award agreements.
b.Disability. The Company may, at its option, terminate the Executive’s employment upon written notice to the Executive if the Executive, because of physical or mental incapacity or disability, fails to perform the essential functions of the Executive’s position, with reasonable accommodation. “Disability” for purposes of this agreement means disability pursuant to the standards set forth in, or in circumstances where the Executive qualifies for receipt of benefits under, the long-term disability plan of the Employer applicable to the Executive. Upon such termination, the Executive’s entitlement to compensation and benefits shall cease immediately, except that the Executive shall be entitled to: (i) accrued Base Salary through and including the effective date of the Executive’s termination of employment; (ii) if applicable, the amount of any annual incentive bonus awarded and payable but not yet paid for the Bonus Year prior to the year in which the Executive’s termination of employment occurs; (iii) prorated annual incentive bonus (based on the target bonus under the Senior Executive Incentive Plan or any successor plan for the Bonus Year in which the Executive’s termination of employment occurs) through and including the effective date of the Executive’s termination of employment; (iv) other Employee Benefits to which the Executive is entitled upon termination of employment in accordance with the terms of the plans and programs of the Company; and (v) payment or vesting of any Long-Term Incentive Awards that have been granted to Executive prior to Executive’s date of termination, to the extent that such payment or vesting is provided for in the terms of the award agreements. In the event of any dispute regarding the existence of the Executive’s incapacity or disability hereunder the matter shall be resolved by the determination of a physician selected by the CEO and reasonably acceptable to the Executive. The Executive shall submit to appropriate medical examinations for purposes of such determination.
c.Termination for Cause. The Company may at any time during the Executive’s employment terminate this Agreement for Cause by written notice of termination given to the Executive setting forth the basis for such termination and giving Executive an opportunity to cure within thirty (30) days. If the Executive does not effect a cure within this period, as determined by the Company in its reasonable discretion, the termination shall become effective. For the purposes of this Agreement, “Cause” will mean the Executive’s: (i) performing a deliberate act of dishonesty, fraud, theft, embezzlement, or misappropriation involving the Executive’s employment with the Company, or breach of the duty of loyalty to the Company; (ii) performing an alleged act of race, sex, national origin, religion, disability, or age-based discrimination or sexual harassment, if after a reasonable investigation, outside or in-house counsel to the Company reasonably concludes that allegations are substantiated; (iii) material violation of Company policies and procedures including but not limited to, the Aon Code of Business Conduct, (iv) material non-compliance with the terms of this Agreement, including but not limited to Sections 7 and 8 hereunder, or any other agreement with the Company or any of its subsidiaries or affiliates, or (v) performing any criminal act resulting in a criminal felony charge brought against the Executive or a criminal conviction of the Executive (other than a conviction of a minor traffic violations). In the event of a termination for Cause, the Company will only be required to pay the Executive all accrued but unpaid Base Salary and vested benefits to which the Executive is entitled upon such termination. In accordance with the terms of the plans and programs of the Company, each as of the effective date of such termination, payable no later than the next regularly scheduled payday after such effective termination date or, if applicable, at such time as set forth in the applicable benefit policy, plan, or programs.
5. Time and Form of Payment. For purposes of this Agreement, the terms “terminated,” “termination,” “termination of employment,” and variations thereof, as used in this Agreement, are intended to mean a termination of employment that constitutes a “separation from service” under Code Section 409A. The time and form of payment of benefits upon termination of employment described in the preceding provisions of Sections 4 and 5 (including expense reimbursements or payment and in-kind benefits) shall be made in accordance with such Sections; provided that any lump sum cash payments shall be paid 60 days following the Executive’s termination of employment; and provided further, with respect to termination of employment for reasons other than death, the payment at such time can be
5



characterized as a “short-term deferral” for purposes of Code Section 409A or as otherwise exempt from the provisions of Code Section 409A, or if any portion of the payment cannot be so characterized, and the Executive is a “specified employee” under Code Section 409A, such portion of the payment shall be delayed until the earlier to occur of the Executive’s death or the date that is six months and one day following the Executive’s termination of employment (the “Delay Period”). Upon the expiration of the Delay Period, all payments and benefits delayed pursuant to this Section 5.c shall be paid or reimbursed to the Executive in a lump sum, without interest, and any remaining payments due under the preceding provisions of Sections 4 or 5, whichever is applicable, shall be payable at the same time and in the same form as such amounts or benefits would have been paid in accordance with their original payment schedule under such Section. If the Executive is a “specified employee” under Code Section 409A, the full cost of the continuation or provision of Employee Benefits (other than any cost of medical or dental benefit plans or programs or the cost of any other plan or program that is exempt from Code Section 409A) under Sections 4 or 5 shall be paid by the Executive until the earlier to occur of the Executive’s death or the date that is six months and one day following the Executive’s termination of employment, and such cost shall be reimbursed by the Company to, or on behalf of, the Executive in a lump sum cash payment on the earlier to occur of the Executive’s death or the date that is six months and one day following Executive’s termination of employment. For purposes of applying the provisions of Section 409A, each separately identified amount to which the Executive is entitled shall be treated as a separate payment.
6.Federal and State Withholding. The Company shall deduct from the amounts payable to the Executive pursuant to this Agreement the amount of all required federal, state, and local withholding taxes in accordance with the Executive’s Form W-4 on file with the Company, and all applicable federal employment taxes.
7.Noncompetition; No solicitation.
a.    General. The Executive acknowledges that in the course of Executive’s employment with the Company he has and will become familiar with trade secrets and other confidential information concerning the Company, including its affiliates (collectively “Aon”) and that Executive’s services will be of special, unique and extraordinary value to Aon. The Executive further acknowledges and agrees that Executive’s services as a senior executive of the Company have been, and are, of special, unique, and extraordinary value to Aon, and that Executive’s material employment duties and responsibilities (including without limitation with respect to Aon strategic and other business operations, clients, prospective clients, and other employees) are global in nature and span geographic areas that extend well beyond the locations in which the Executive has been physically employed and resided. The Executive further acknowledges and agrees that it therefore is reasonable to protect Aon against certain competitive activities by the Executive for a limited period of time after the Executive terminates Executive’s employment to protect Aon’s legitimate business interests in all of the geographic areas in which Aon does business, and that the covenants contained in Section 7 are necessary for the protection of Aon and are reasonably limited with respect to the activities prohibited, duration, geographical scope and their effect on the Executive and the public.

b.    Confidential Information. The Executive acknowledges that Aon’s business depends to a significant degree upon the possession of confidential, proprietary and trade secret information, which is not generally known to others, and that the profitability of the business of Aon requires that this information remain proprietary to Aon. The Executive recognizes that, by virtue of the Executive’s employment by the Company and/or its affiliates, and to assist the Executive in the solicitation, production and servicing of client business, the Executive has otherwise prohibited access to such information. This Confidential Information (defined below) includes, without limitation: non-public lists of clients and prospective clients; contract terms and conditions; client information relating to services, insurance, benefits programs, executives, finances, and compensation; copyrighted materials; corporate, management and business plans and strategies; compensation and revenues; methods and strategies of marketing; market research and data; technical know-how; proprietary computer software which Aon uses in its business, and which gives Aon an opportunity to obtain an
6



advantage over competitors who do not know or use it, and other information owned, licensed or developed by Aon; and the conduct of the affairs of Aon.

c.    Noncompetition. The Executive agrees that during the period of Executive’s employment with the Company and for a period of two years after such employment ends, except as provided for in Section 1.a.iv., (inclusive of any period of employment with a successor) (the “Noncompetition Period”) he shall not in any manner, directly or through the direction or assistance of others, through any person, firm or corporation, alone or as a member of a partnership or as an officer, director, stockholder, investor or employee of or consultant to any other corporation or enterprise or otherwise, engage or be engaged, or assist any other person, firm, corporation or enterprise in engaging or being engaged, in any business, in which the Executive was involved or with respect to which Executive was provided Confidential Information, being conducted by, or actively contemplated by, the Company or any of its affiliates as of the time employment ends , including, but not limited to, the business of insurance brokerage and consulting, reinsurance brokerage and consulting, employee health and retirement benefits brokerage and consulting, or human resources consulting (“Competitive Business”). Competitive Business includes (i) any business that provides any products or services competitive to those in which the Executive had material involvement during the twenty-four (24) months prior to the termination of Executive’s employment with the Company (the “Look Back Period”), and (ii) any private equity firm or investment entity that owns or controls, directly or indirectly, any portfolio company engaged in insurance brokerage, reinsurance brokerage, or related consulting service and has aggregate assets under management or investments exceeding $10 billion.

Nothing in this Section 7(c) shall be construed to prohibit Executive’s employment in a separately operated subsidiary or other business unit of a company that would not be a competitor but for common ownership with a competitor so long as Executive provides written assurances regarding the non-competitive nature of Executive’s position that are satisfactory to the Company and the Executive’s new employer confirms this understanding. For the avoidance of doubt, and without limiting the generality of the foregoing prohibition, the following are Competitive Businesses as of the Effective Date: Marsh & McLennan Companies, Inc., Willis Towers Watson plc, Arthur J. Gallagher & Co., Alliant Insurance Services, Howden, Lockton, USI, and Brown & Brown (including any of the foregoing entities’ affiliates or successors in interest that are Competitive Businesses).

d.Nonsolicitation of Clients. The Executive also agrees that during the Noncompetition Period he shall not in any manner, directly or through the direction or assistance of others, solicit or induce, or cause any person or other entity to solicit or induce, any client or customer of Aon with whom or with respect to which Executive had business-related contact during the Look Back Period or about whom/which Executive had access to Confidential Information during the Look Back Period, to engage in business that is competitive with Aon’s business or to stop or reduce their business with Aon.

e.Nonsolicitation of Employees. The Executive further agrees that during the Noncompetition Period, he shall not in any manner, directly or through the direction or assistance of others, solicit or induce, or cause any person or other entity to solicit or induce any employee of Aon with whom Executive had business related-contact or about whom Executive had access to Confidential Information (such as management’s assessment of the employee’s skills and performance) during the Look Back Period, to work for the Executive or for any third party or entity, or to terminate or abandon his or her employment for any purpose whatsoever.

f.Exceptions. Nothing in this Section 7 shall prohibit the Executive from being (i) a stockholder in a mutual fund or a diversified investment company or (ii) passive owner of not more than two percent of the outstanding stock of any class of a corporation, any securities of which are publicly traded, so long as Executive has no active participation in the business of such corporation.

7



g.Reformation. If, at any time of enforcement of this Section 7, a court holds that the restrictions stated herein are unreasonable under circumstances then existing, the parties hereto agree to the partial enforcement of the restriction to such lesser degree as would make it reasonable or enforceable, or that the maximum period, scope or geographical area reasonable under such circumstances shall be substituted for the stated period, scope or area and that the court shall be allowed to revise the restrictions contained herein to cover the maximum period, scope and area permitted by law. This Agreement shall not authorize a court to increase or broaden any of the restrictions in this Section 7.

h.Consideration; Breach. The Company and the Executive agree that the benefits to be provided by the Company to the Executive pursuant to Section 3(d) (the Special Award) shall be provided in consideration of the Executive’s agreements contained in Section 7 hereof and that such consideration is sufficient to make the covenants in Section 7 immediately enforceable and binding against him. In the event that the Executive shall commit a breach of any provision of Section 7 hereof, the Company shall be entitled immediately to suspend all remaining payments pending expiration of any cure period provided to Executive for a breach under this Agreement, and if the breach is not cured as permitted under this Agreement to then terminate making all remaining payments and providing all remaining benefits pursuant to Section 3 hereof and upon such event the Company shall have no further liability to the Executive under this Agreement.

i.Other Restrictive Covenants. Notwithstanding any other language in the Agreement, this Agreement does not preclude the enforceability of any restrictive covenant provision contained in any prior or subsequent agreement entered into by the Executive (any such covenant, an “Other Covenant”). Further, no Other Covenant precludes the enforceability of any provision contained in this Agreement. No subsequent agreement entered into by the Executive may amend, supersede, or override the covenants contained herein unless such subsequent agreement specifically references Section 7 of this Agreement. The Executive further acknowledges and agrees that, in addition to the provisions of this Section 7 Executive remains subject to certain restrictive covenants by virtue of Executive’s receipt of certain stock benefits under the Stock Plan. To the extent any conflict exists between the restrictions set forth in this Agreement and the Other Covenants, the Company shall be provided the greatest protection set forth in either agreement. In the unlikely event that a post-employment restriction provided for in this Section 7 is deemed void by a controlling court, arbiter, or other binding adjudicator, any restriction addressing the same or similar conduct by Executive in the Prior Agreement will resume effect so that the Company’s legitimate, protectable interests remain protected.

8.image_0.jpgConfidentiality. The Executive shall not make use of or disclose, directly or indirectly, any (i) trade secret or other confidential or secret information of Aon or (ii) other technical, business, proprietary or financial information of Aon not available to the public generally or to the competitors of Aon, that the Executive acquires or gains access to in the course of the Executive’s employment with the Company (“Confidential Information”), except to the extent that such Confidential Information (A) becomes a matter of public record or is published in a newspaper, magazine or other periodical available to the general public, other than as a result of any act or omission of the Executive, (B) is required to be disclosed by any law, regulation or order of any court or regulatory commission, department or agency, provided that the Executive gives prompt notice of such requirement in any non-governmental agency proceeding to the Company to enable the Company to seek an appropriate protective order, or (C) is necessary to perform properly the Executive’s duties under this Agreement. If the Executive does not retain copies of Confidential Information after the termination of their employment with the Company, the restrictions in this Section 8 on use or disclosure of Confidential Information will expire three (3) years after the termination of the Executive’s employment with the Company, where information that does not qualify as a trade secret is concerned; however, the restrictions will continue to apply to trade secret information for as long as the information at issue remains qualified as a trade secret. The Executive agrees that all records, in any form (such as email, database, correspondence, notes, files, contact lists, drawings, specifications, spreadsheets, manuals, and calendars) that contain Confidential Information, with the exception of wage and benefit related materials provided to the Executive as an employee for his own use as an employee, are the property of Aon (collectively “Company Records”).
8



The Executive will follow all Aon policies regarding use or storage of Company Records and return all such records (including all copies) when the Executive’s employment with the Company terminates or sooner if requested. The Executive agrees that he will not copy, delete, or alter any information contained upon the Executive’s Company computer or Company equipment before the Executive returns it to the Company. In addition, if the Executive has used any personal computer, server, cloud account, or e-mail system (collectively “Personal Devices and Accounts”) to receive, store, review, prepare or transmit any Aon information (which Executive understands Aon does not permit), including but not limited to, Confidential Information, the Executive agrees to provide the Company with a computer-useable copy of all such Confidential Information and then cooperate with the Company regarding any necessary remediation to ensure all Confidential Information has been returned. Executive agrees to provide the Company with necessary passwords and access to any such Personal Devices and Accounts as reasonably requested as part of the remediation process. Aon has no responsibility for the deletion of any non-Aon Confidential Information. Aon will not make any effort to recover any non-Aon Confidential Information, application or software that is deleted. Executive acknowledges that they have been advised not to use any Personal Devices and Accounts in the course of Executive’s job duties for the Company. Promptly following the Executive’s termination of employment or sooner upon the Company’s request, the Executive shall surrender to the Company all records, memoranda, notes, plans, reports, computer tapes and software and other documents and data which constitute Confidential Information which he may then possess or have under Executive’s control (together with all copies thereof).
9.Inventions. The Executive hereby assigns to the Company Executive’s entire right, title and interest in and to all discoveries and improvements, patentable or otherwise, trade secrets and ideas, writings and copyrightable material, which may be conceived by the Executive or developed or acquired by Executive during the Executive’s employment, which may pertain directly or indirectly to the business of the Company or any of its affiliates. The Executive agrees to disclose fully all such developments to the Company upon its request, which disclosure shall be made in writing promptly following any such request. The Executive shall, upon the Company s request, execute, acknowledge and deliver to the Company all instruments and do all other acts which are necessary or desirable to enable the Company or any of its subsidiaries to file and prosecute applications for, and to acquire, maintain and enforce, all patents, trademarks and copyrights in all countries. This Agreement s assignment provisions are limited to only those inventions that can be lawfully assigned by an employee to an employer. The forgoing invention assignment obligation does not apply to an invention for which no equipment, supplies, facility, or trade secret information of the employer (Aon) was used and which was developed entirely on the employee's (Executive’s) own time, unless (a) the invention relates (i) to the business of the employer, or (ii) to the employer's actual or demonstrably anticipated research or development, or (b) the invention results from any work performed by the employee for the employer.
10. Enforcement. The parties hereto agree that Aon would be damaged irreparably in the event that any provision of Section 7, 8, or 9 of this Agreement were not performed in accordance with its terms or were otherwise breached and that money damages would be an inadequate remedy for any such nonperformance or breach. Accordingly, the Company and its successors and permitted assigns shall be entitled, in addition to other rights and remedies existing in their favor, to seek an injunction or injunctions to prevent any breach or threatened breach of any of such provisions and to enforce such provisions specifically. The Executive agrees that he will submit himself to the personal jurisdiction of the courts of the State of New York in any action by the Company to enforce any provision of Section 7, 8, or 9 of this Agreement. The Executive acknowledges that he had fourteen (14) days to review this Agreement prior to signing it and was advised to consult with an attorney.
