The Executive’s employment pursuant to the terms of this Agreement will commence on May 12, 2025 (the “Effective Date”). The Executive’s employment will be for an initial term of three years ending on the third anniversary of the Effective Date (the “Initial Term”); provided, however, that the Initial Term will automatically renew for successive one-year periods (each a “Renewal Period,” and together with the Initial Term, the “Term”) unless either party provides notice to the other of its intent not to renew the Term at least one-hundred and twenty (120) days prior to the expiration of the Initial Term or any subsequent Renewal Period.

Notwithstanding the foregoing, the Term will expire immediately upon the termination of the Executive’s employment in accordance with the terms and conditions of Section 9 of this Agreement. The Executive understands and agrees that he may be required to travel from time to time for business reasons.

3.    Base Salary. The Executive will be compensated $30,208 per semi-monthly pay period, which is equivalent to $725,000 on an annualized basis. The Executive’s base salary will be reviewed annually for increase and it and all other compensation from the Group is subject to legally-required and employee-authorized withholdings and payable in accordance with the Company’s standard payroll practices.

4.    Variable Compensation. As an employee of JHIUS, the Executive will be eligible to participate in annual discretionary variable compensation opportunities, beginning in 2025, per the terms of the variable compensation program. The annual variable compensation may be based on a combination of individual and Group-related performance objectives, each of which shall be determined in good faith by the HCCC. The actual variable compensation earned will be dependent on the level of achievement of applicable goals. As of the Effective Date, annual variable compensation is apportioned as 40% cash and 60% deferred equity awards (“Deferrals”). Deferrals will be awarded in the form of JHG restricted stock units (40%) and performance share units (60%). This structure is subject to change at any time with or without notice at the discretion of the HCCC. Deferred awards and cash bonuses are generally paid/distributed during the first quarter of each calendar year (for performance in the previous calendar year), and are subject to the Group’s policies related to malus and claw-back. Time-based deferred awards vest ratably over three years and performance share units generally cliff vest at the end of three years based on achievement of relevant performance measures, in either case, subject to continued employment with the Group through the applicable vesting date or in accordance with provisions on termination of employment in the appliable award agreement. For 2025, the Executive’s target variable compensation will be $12,775,000. For each subsequent year, it is expected, but for the avoidance of doubt is not guaranteed, that the Executive’s target variable compensation will be no less than $12,775,000. The targeted value of the cash portion of the Executive’s variable compensation with respect to any performance period during the Term shall be referred to herein as the “Target Cash Bonus”.

5.    Special Award.

For the avoidance of doubt, the Special Award will not be governed by the terms described in Section 4 of this Agreement. The Special Award will be made to the Executive as soon as practicable following the Effective Date and in accordance with the Janus Henderson Group plc Deferred Incentive Plan, or any successor thereto (the “DIP”) granting procedures.

6.    Benefits. As an employee of JHIUS, the Executive will be eligible to continue to participate in JHIUS’s flexible benefits program and the Company’s 401(k) program. The Executive shall also be subject to the travel (including travel to and from Denver, New York, and London) and reimbursement policies commensurate with the Executive’s role and no less favorable than those provided to other senior executives of the Group and shall be eligible for all perquisites provided to other senior executives of the Group. The Executive will receive audit support and tax equalization benefits for compensation includable in income in accordance with the Company’s Global Mobility Tax Equalisation Policy (TEQ).

7.    Employment and Group Policies. The Executive’s employment with JHIUS is at-will and either the Executive or the Company may terminate the relationship at any time with or without Cause. During the Term the Executive will be expected to comply with the Group’s current Employee Policies and Guidelines, as they may be amended from time to time; provided that, except as required by applicable law (including United States securities laws), governmental regulation, remuneration code requirements, or stock exchange listing requirements, for purposes of any plan or arrangement of the Group in which the Executive participates, the definition of "cause" in any such plan or arrangement as applicable to the Executive shall be the definition of Cause set forth herein. The companies in the Group will not maintain existing or sponsor new industry registrations or licenses where not supported by the Executive’s job functions (as determined by the Company at its sole discretion). As the CEO, the Executive’s employment is subject to the Executive’s continued maintenance of his registration by the Financial Conduct Authority (FCA).

8.    Service on Boards. During the Term, in addition to performing the role of CEO, the Executive will serve as a member of the Board or other Company-related boards if nominated to that role. The Executive shall devote his full professional time and attention to the business and affairs of the Company to discharge the responsibilities of a CEO, provided that, notwithstanding the foregoing, the Executive shall be permitted, without any approval to serve on civil or charitable boards or committees and to manage personal and family investments, in each case, so long as such activities do not (x) interfere with the performance of the Executive’s responsibilities to the Company or (y) violate Section 10 of this Agreement. The approval of the Board shall be required to serve on any corporate board on which the Executive does not currently serve. In serving on such other corporate board, the Executive will resign from such board if requested to do so by the Board. It is acknowledged and agreed that, as of the date hereof, the Executive serves as a member of the board of directors of Sysco Corporation and that such service does not violate the terms of this paragraph.

(a)    Severance Payments. Subject to the conditions set forth in this Section 9 and Section 20 hereof, including the Executive’s execution and non-revocation of the Release provided under Section 9(c) hereof and the Executive’s continued compliance with the covenants and obligations in this Agreement (including Section 10) and the Release, the Executive shall receive the following (the “Severance Payments”) in the event that the Executive’s employment is terminated by the Company without Cause or the Executive resigns for Good Reason: (i) an amount equal to 3.0 times the Executive’s Annual Total Cash Compensation, which shall be paid to the Executive on the first regularly scheduled payroll date of the Company that occurs on or following the 60th day after the date of termination (the “Payment Date”); (ii) continued vesting of any then-unvested time- and performance-based restricted stock units in respect of JHG common stock in accordance with the vesting schedule in the applicable award agreement; and (iii) any unpaid portion of the Executive’s variable compensation (with no negative discretion applied and any individual or subjective goals deemed met at target performance) with respect to any fiscal year that has ended prior to the date of termination, payable on the Payment Date and (iv) a lump sum cash payment equal to the product of (A) the Target Cash Bonus and (B) a fraction, the numerator of which is the number of days in the bonus year through the date of termination and the denominator of which is 365, payable on the Payment Date. The Severance Payments hereunder shall be in lieu of any other severance payments to which the Executive would be entitled pursuant to any other severance plans, programs, arrangements, or policies of the Company, and shall be considered a part of, and not in addition to, any amounts that may be payable to the Executive under the Worker Adjustment Retraining Notification Act of 1988 or any similar state statute or regulation. Notwithstanding any provision of the DIP or otherwise to the contrary, all provisions of the DIP that apply upon a termination by the Company without Cause shall also apply upon a resignation for Good Reason. No Severance Payments or other termination or severance payments, benefits or indemnities shall be paid to the Executive in the event that the Company terminates the Executive’s employment for Cause or if the Executive resigns from his employment with the Company without Good Reason (including as a result of the Executive’s nonrenewal of the Term in accordance with Section 2 of this Agreement).

The benefits otherwise receivable under this Section 9(b) shall be eliminated or reduced to the extent benefits of the same or similar type are received by or made available to the Executive during the applicable statutory period following the Executive’s date of termination of employment, and the Executive undertakes to promptly report to the Company the receipt of such benefits. The amount of the benefits provided pursuant to this Section 9(b) during any calendar year may not affect benefits provided in any other calendar year. The Executive shall be responsible for any payment of taxes, interest and/or penalty imposed on the Executive resulting from such benefits.

(c)    General Release. The receipt of the payments described in Sections 9(a) and 9(b) hereof shall be conditioned upon the execution and non-revocation by the Executive and the Company of a general release of all claims substantially in such form as attached as Exhibit C (the “Release”).

In the event that the Executive’s employment with the Company is terminated for any reason (or no reason), the Company shall pay the Executive (or the Executive’s legal representative) (i) any unpaid Base Salary earned by the Executive, and any unused paid time off accrued by the Executive, through the date of termination, (ii) any expenses incurred but not yet reimbursed in accordance with the terms of the applicable Group reimbursement policies and procedures, and (iii) any vested employee benefits to which the Executive is entitled as of the date of termination under the employee benefit plans of the Company.

Notwithstanding any provision of any plan, program, agreement or arrangement maintained by any member of the Group for the benefit of the Executive or in which the Executive participates to the contrary, incentive compensation granted or provided to the Executive shall also be subject to such additional forfeiture, claw-back, deduction or recovery provisions as may be required pursuant to any applicable laws (including United States securities laws), government regulations, remuneration code requirements, stock exchange listing requirements or policies of the Group in effect from time to time (including additional laws, regulations and requirements implemented following the date hereof); provided, that except as may be required pursuant to any applicable laws (including United States securities laws), government regulations, remuneration code requirements, or stock exchange listing requirements, such provisions shall be substantially comparable to those in effect as of the date hereof.

(i)    The Executive agrees that all information and know-how, whether or not in writing or any other form or medium, of a private, secret or confidential nature concerning the business or financial affairs of any member of the Group is and shall be the exclusive property of the Group. Such information and know-how shall include, but not be limited to, trade secrets, ideas, skills, knowledge, improvements, works of authorship, inventions (whether or not patentable), products, processes, methods, techniques, formulas, compositions, projects, developments, plans, research data, financial data, personnel data, technical, business, financial, customer and product development plans and forecasts, salaries and terms of compensation of employees, computer programs, computer codes, algorithms, modules, scripts, features, and modes of operation, designs, technology, internal documentation and employee, customer and supplier lists, contacts at or knowledge of current or prospective customers of any member of the Group or their clients, and such other information concerning any member of the Group not generally known to the public (collectively, “Proprietary Information”).

The Executive understands that during the Executive’s employment, due to the nature of the Executive’s position, the Executive will have access to and knowledge of Proprietary Information (including, without limitation, trade secrets of the Group) thereby creating a relationship of confidence and trust between the Executive and the Group with respect to Proprietary Information.

The Executive understands that the Company possesses or will possess Company Materials that are important to the Group, and the customers and employees of the Group, and the Executive agrees to deliver to the Company upon the Executive’s termination of employment with the Company or at such other times as requested by the Company all Company Materials in the Executive’s possession, custody or control or to certify to the loss or destruction of such Company Materials.

(iii)    The Executive agrees that the Executive’s obligation not to disclose or use information, know-how and records of the types set forth in Sections 10(a)(i) and 10(a)(ii) hereof, also extends to such types of information, know-how, records and tangible property of customers of any member of the Group or suppliers to any member of the Group or other third parties who may have disclosed or entrusted the same to any member of the Group or to the Executive in the course of any member of the Group’s business.

(iv)    Without limiting the Executive’s rights under Section 10(e), in the event that the Executive is requested pursuant to, or becomes compelled by, any applicable law, regulation, or legal process to disclose any Proprietary Information or Company Materials, the Executive shall provide the Company with prompt written notice thereof so that the Company, or an Affiliate, may seek a protective order or other appropriate remedy or, in the Company’s sole and absolute discretion, waive compliance with the terms hereof. In the event that no such protective order or other remedy is obtained, or the Company waives compliance with the terms hereof, the Executive shall furnish only that portion of such Proprietary Information or Company Materials which the Executive is advised by his counsel and agreed to with Company counsel is legally required. The Executive shall cooperate with the Company, at the Company’s sole cost and expense, in its efforts to obtain reliable assurance that confidential treatment shall be accorded such Proprietary Information and Company Materials.

(b)    Non-Disparagement. Subject to Section 10(e), during the Executive’s employment with the Company and for a period of at least three (3) years following termination of his employment for any reason, neither the Executive nor senior executive officers of JHG shall make any statement that is intended to or would be reasonably likely to disparage or encourage or induce others to disparage any member of the Group or any of its or their past and present officers, directors, products or services, on the one hand, or the Executive and his services, on the other. For purposes of this Agreement, the term “disparage” includes, without limitation, any comment or statement that is intended to or would be reasonably likely to disparage: (i) the conduct of any business, services or products of any member of the Group (including, without limitation, any business plans or prospects) or the Executive, as applicable, or (ii) the business or personal reputation of any member of the Group or any of its or their past and present officers, directors, products or services or the Executive or his services, as applicable. Nothing in this Section 10(b) is intended to or shall prevent the Executive from engaging in permitted disclosures as described in Section 10(e) below. The Company may not seek to enforce this Section 10(b) if a court or arbitrator of competent jurisdiction determines that a senior executive officer of JHG has been proven to disparage the Executive to a third party in violation of this Section 10(b); and the Executive may not seek to enforce this Section 10(b) if a court or arbitrator of competent jurisdiction determines that the Executive has been proven to disparage a senior executive officer of JHG to a third party in violation of this Section 10(b).

(i)    During the Executive’s employment with the Company and for a period of twelve (12) months following termination of employment for any reason (the “Restricted Period”), without the prior written consent of the Company, the Executive shall not, within the United States, United Kingdom or any other city, county, state, commonwealth, province, territory, country or political subdivision in which the Group operates or has taken steps to operate prior to the termination of the Executive’s employment, directly or indirectly, either for the Executive or any other person or entity, whether alone or in association with any person, firm, corporation or other business organization, manage, control, be employed or engaged in a management, director- or officer-, or executive-level role with, or provide advice or render services (whether as an employee, consultant, advisor, partner, member, contractor, or otherwise) that are similar in purpose or function to any advice or services provided or rendered by the Executive to or on behalf of the Company or Group for or on behalf of, any Competitive Business or any person or entity that engages in or has taken material steps to prepare to engage in any Competitive Business; provided that it shall not be a violation of this Section 10(c)(i) for the Executive to do any of the foregoing at an entity or an affiliated group of entities that engage in or has taken material steps to prepare to engage in, or owns, invests in, manages, conducts or controls any venture or enterprise engaged in or preparing to engage in, a Competitive Business so long as the Executive is not involved in such Competitive Business. Nothing herein shall prohibit the Executive from being a passive owner of the equity securities of a corporation engaged in any Competitive Business, so long as the Executive has no active participation in the business of such corporation. As used herein, the term “Competitive Business” shall mean any business which provides investment advisory or investment management services. Service on other boards approved by the Board and as permitted pursuant to this Agreement, is not considered a violation of this paragraph 10(c).

(ii)    During the Restricted Period, the Executive shall not, directly or indirectly, (A) knowingly interfere with any relationship which may exist from time to time between any member of the Group and any of its or their employees, consultants, agents or representatives, (B) solicit, hire or attempt to hire, or assist another in soliciting, hiring or attempting to hire, any person who is an employee or contractor of any member of the Group with whom the Executive worked, had dealings, had contact or otherwise developed a relationship, or about whom the Executive accessed or possessed Proprietary Information while employed by the Company, (C) divert, attempt to divert, or solicit, or assist another in diverting, attempting to divert or soliciting, the customer business or account of, or accepting any approach from, any Protected Client or (D) violate any other terms related to unfair interference or non-solicitation, pursuant to the DIP and any long-term incentive awards. Notwithstanding the foregoing, it shall not be a violation of this Section 10(c) for the Executive to (i) solicit or hire independent accounting, legal and similar firms or his personal assistant or (ii) following termination of the Executive’s employment, initiating non-targeted general advertisements or public recruitment solicitations that are not directed or targeted at employees or service providers of the Company or the Group.

(iii)    The Executive acknowledges the highly competitive nature of the business of the Group and the relationship of confidence and trust between the Executive and the Group. Accordingly, the Executive acknowledges and agrees that the restrictions contained in this Agreement are reasonable and necessary for the protection of the legitimate business interests of the Group, that any violation of these restrictions would cause substantial and irreparable injury to the Group, and these restrictions will not cause an undue hardship. In addition, in accordance with Colorado Rev. Stat. § 8-2-113, the Executive acknowledges and agrees that (a) the Executive is being provided with a “Notice of Restrictive Covenants” at the same time the Executive is being provided with this Agreement, and (b) this Agreement shall become effective on the later of the date on which the Executive signs this Agreement and the date that is fourteen (14) days after the date on which the Executive receives the “Notice of Restrictive Covenants,” which the Executive understands is being provided to him in a separate document attached hereto. The Executive specifically acknowledges and agrees that the Executive is receiving independent adequate consideration for the non-competition restrictive covenant and other restrictions herein.

(iv)    If, at the time of enforcement of this Section 10(c), an arbitrator or court shall hold that the duration, scope, area or other restrictions stated herein are unreasonable under circumstances then existing, the Executive and the Company agree that it is the intention of the parties that such provision should be enforceable to the maximum extent permissible under applicable law. The Executive and the Company further agree that any arbitrator or court is expressly authorized to and shall modify any unenforceable provision of this Agreement instead of severing the unenforceable provision from this Agreement in its entirety, whether by rewriting the offending provision, deleting any or all of the offending provision, adding additional language to this Agreement, or by making any other modifications it deems warranted to carry out the intent and agreement of the parties to the maximum extent permitted by law. The parties expressly agree that this Agreement as so modified by the arbitrator or court shall be binding upon and enforceable against each of them.

(d)    Enforcement; Forfeiture. In the event of a breach or threatened breach of any of the provisions contained in this Section 10, the Executive agrees that the Company shall be entitled to injunctive or other equitable relief in a court of appropriate jurisdiction to remedy any such breach or threatened breach, and the Executive acknowledges that damages would be inadequate and insufficient. The existence of this right to injunctive and other equitable relief shall not limit any other rights or remedies that the Company may have at law or in equity including, without limitation, the right to recoupment under Section 9(i) and monetary, compensatory and punitive damages.

(e)    Permitted Disclosures. Pursuant to 18 U.S.C. §1833(b), the Executive shall not be held criminally or civilly liable under any Federal or State trade secret law for the disclosure of a trade secret of the Company that (i) is made (A) in confidence to a federal, state, or local government official, either directly or indirectly, or to the Executive’s attorney, and (B) solely for the purpose of reporting or investigating a suspected violation of law; or (ii) is made in a complaint or other document that is filed under seal in a lawsuit or other proceeding. If the Executive files a lawsuit for retaliation by the any member of the Group for reporting a suspected violation of law, the Executive may disclose the trade secret to the Executive’s attorney and use the trade secret information in the court proceeding, if the Executive (1) files any document containing the trade secret under seal, and (2) does not disclose the trade secret, except pursuant to court order. Nothing in this Agreement is intended to conflict with U.S.C. §1833(b) or create liability for disclosures of trade secrets that are expressly allowed by such section. Further, nothing in this Agreement or any agreement the Executive has with any member of the Group shall prohibit or restrict the Executive from (i) voluntarily communicating with an attorney, tax or financial advisor retained by the Executive (confidentiality restrictions applicable in this Agreement shall similarly be applicable to them); (ii) recovering a Securities and Exchange Commission (“SEC”) whistleblower award as provided under Section 21F of the Securities Exchange Act of 1934; (iii) providing testimony in response to a valid subpoena, court order, regulatory request or other judicial, administrative or legal process; or (iv) communicating with or making any voluntary disclosure of information or documents to any law enforcement or government agency, including the SEC, the Equal Employment Opportunity Commission (“EEOC”), the Colorado Civil Rights Commission, the New York State Division on Human Rights, or any other state or local commission on human rights or similar entity, or any other self-regulatory organization related to any violation of law, in each case, without advance notice to the Company. Notwithstanding the foregoing, nothing in this Agreement shall prevent the Executive from disclosing the underlying facts of any alleged discriminatory or unfair employment practices to (1) Executive’s religious advisor, medical or mental health provider, mental or behavioral health therapeutic support group, (2) any government agency for any reason, without any obligation to first notify the Company, (3) in response to legal process without any obligation to first notify the Company, and (4) for all other purposes required by law.

(f)    Survival. The terms and provisions of Sections 9 and 10 shall survive the Executive’s termination of employment with the Company for any reason and shall be fully enforceable thereafter, and the terms and provisions of Section 10 shall apply regardless of whether the Executive executes the Release. The provisions of this Section 10 shall be the sole restrictive covenants to which the Executive is subject and shall supersede the covenants in the DIP or the applicable award agreement, unless the award agreement expressly provides otherwise.

11.    Indemnification. The Company shall indemnify and hold the Executive harmless (including advancement of expenses) to the fullest extent permitted by law, and shall cover the Executive under any insurance policy the Company maintains for the errors and omissions of its directors and officers, in connection with the Executive’s service as an officer and director of the Company and at coverage levels appropriate for the Company and the Executive’s positions with the Group (as determined from time to time by the Board) and consistent with levels provided to and expenses covered for all other directors and officers of the Company. Such indemnification and coverage shall survive termination of the Executive’s employment and/or this Agreement.

12.    Cooperation. The Executive hereby agrees that, following termination of employment for any reason, the Executive shall reasonably cooperate with the Group in providing information and assistance that any member of the Group reasonably requests and in taking such other action as such member of the Group may reasonably request including, without limitation, consultation concerning the Executive’s areas of responsibility. The Executive further agrees to reasonably assist the Group with respect to all reasonable requests to testify in connection with any legal proceeding or matter relating to any member of the Group, including, but not limited to, any federal, state or local audit, proceeding or investigation, other than proceedings relating to the enforcement of this Agreement or other proceedings in which the Executive is a named party whose interests are adverse to those of any member of the Group. The Company shall reimburse any reasonable out-of-pocket expenses incurred by the Executive incurred at the request of the Company in connection with any such cooperation or participation with travel commensurate with the travel enjoyed by the Executive prior to termination. All services provided hereunder shall be subject to the indemnification and D&O coverage provided under Section 11 of this Agreement.

13.    Notices. Any notice or other communication required or permitted to be given under this Agreement (a “Notice”) shall be in writing and delivered in person, electronically, by overnight courier service or by postage prepaid mail with a return receipt requested, at the following locations (or to such other address as either party may have furnished to the other in writing by like Notice.

14.    Arbitration. Except as specifically provided herein, any dispute, controversy or claim arising under or in connection with this Agreement (including the Release) or otherwise relating in any way to the Executive’s employment relationship or the termination thereof, whether based in contract, tort, statute, common law or any other legal theory, shall be submitted to and decided by binding arbitration, conducted before a single arbitrator in the State of Colorado and administered by the American Arbitration Association (“AAA”) in accordance with the AAA’s employment arbitration rules then in effect as well as any requirements of applicable state and federal law. A copy of the current version of AAA’s employment arbitration rules is available at https://www.adr.org/employment. Judgment may be entered on the arbitrator’s award in any court having jurisdiction. To the extent permitted by applicable law, each party shall bear their own costs and expenses of any such arbitration proceeding, if any. In the event of any dispute or controversy hereunder, each party hereto shall be responsible for its own legal fees. For the avoidance of doubt, this Section 14 shall not apply to any dispute, controversy or claim that, as a matter of law, the parties cannot be compelled to arbitrate under applicable federal, state, or local law.

15.    Waiver of Breach. Any waiver of any breach of this Agreement shall not be construed to be a continuing waiver or consent to any subsequent breach on the part either of the Executive, the Company.

16.    Non-Assignment; Successors. This Agreement is personal to each of the parties hereto. Except as provided in this Section 16, no party may assign or delegate any rights or obligations hereunder without first obtaining the advanced written consent of the other party hereto. Any purported assignment or delegation by the Executive in violation of the foregoing shall be null and void ab initio and of no force and effect. The Company may assign this Agreement to a person or entity that is an Affiliate or to any successor to all or substantially all of the business and/or assets of the Company which assumes in writing, or by operation of law, the obligations of the Company hereunder. As used in this Agreement, “Company” shall mean the Company and any successor to its business and/or assets, which assumes and agrees to perform this Agreement by operation of law, or otherwise.

17.    Severability. To the extent that any provision of this Agreement or portion thereof shall be invalid or unenforceable, it shall be considered deleted therefrom and the remainder of such provision and of this Agreement shall be unaffected and shall continue in full force and effect.

18.    Counterparts. This Agreement may be executed in one or more counterparts, each of which shall be deemed to be an original but all of which together shall constitute one and the same instrument.

19.    Governing Law. All issues and questions concerning the construction, validity, enforcement and interpretation of this Agreement shall be governed by, and construed in accordance with, the laws of the State of Colorado, without giving effect to any choice of law or conflict of law rules or provisions that would cause the application hereto of the laws of any jurisdiction other than the State of Colorado. In furtherance of the foregoing, the internal law of the State of Colorado shall control the interpretation and construction of this Agreement, even though under any other jurisdiction’s choice of law or conflict of law analysis the substantive law of some other jurisdiction may ordinarily apply.

20.    Compliance with 409A. The parties intend for the payments and benefits under this Agreement to be exempt from Section 409A of the Code (“Section 409A”) or, if not so exempt, to be paid or provided in a manner which complies with the requirements of such section, and intend that this Agreement shall be construed and administered in accordance with such intention. If any payments or benefits due to the Executive hereunder would cause the application of an accelerated or additional tax under Section 409A, such payments or benefits shall be restructured in a manner which does not cause such an accelerated or additional tax. For purposes of the limitations on nonqualified deferred compensation under Section 409A, each payment of compensation under this Agreement or any other agreement by and between the Executive and the Company and its Affiliates shall be treated as a separate payment of compensation. Without limiting the foregoing and notwithstanding anything contained herein to the contrary, to the extent required in order to avoid accelerated taxation and/or tax penalties under Section 409A amounts that would otherwise be payable and benefits that would otherwise be provided pursuant to this Agreement or any other agreement by and between the Executive and the Company and its Affiliates during the six-month period immediately following the Executive’s separation from service shall instead be paid on the first business day after the date that is six months following the Executive’s termination date (or death, if earlier). Notwithstanding anything to the contrary in this Agreement, all (A) reimbursements and (B) in-kind benefits provided under this Agreement or any other agreement by and between the Executive and the Company and its Affiliates shall be made or provided in accordance with the requirements of Section 409A, including, where applicable, the requirement that (x) the amount of expenses eligible for reimbursement, or in kind benefits provided, during a calendar year may not affect the expenses eligible for reimbursement, or in kind benefits to be provided, in any other calendar year; (y) the reimbursement of an eligible expense will be made no later than the last day of the calendar year following the year in which the expense is incurred; and (z) the right to reimbursement or in kind benefits is not subject to liquidation or exchange for another benefit.

21.    Entire Agreement. This Agreement constitutes the entire agreement by the Company and the Executive with respect to the subject matter hereof, and supersedes any and all prior agreements or understandings between the Executive and the Company with respect to the subject matter hereof, whether written or oral, including the Prior Agreements. This Agreement may be amended or modified only by a written instrument executed by the Executive and the Company.

22.    Better-Off Cut-Back. Anything in this Agreement to the contrary notwithstanding, in the event that the Accounting Firm shall determine that receipt of all Payments would subject the Executive to tax under Section 4999 of the Code, the Accounting Firm shall determine whether some amount of Payments meets the definition of “Reduced Amount.” If the Accounting Firm determines that there is a Reduced Amount, then the aggregate Payments shall be reduced to such Reduced Amount. If the Accounting Firm determines that the aggregate Payments should be reduced to the Reduced Amount, the Accounting Firm shall promptly give the Company notice to that effect and a copy of the detailed calculation thereof, and the Executive may then elect, in his sole discretion, which and how much of the Payments shall be eliminated or reduced (as long as after such election the Present Value of the aggregate Payments equals the Reduced Amount). All determinations made by the Accounting Firm under this Section shall be binding upon the Company and the Executive. In connection with making determinations under this Section, the Accounting Firm shall take into account the value of any reasonable compensation for services to be rendered by the Executive, including any non-competition provisions that may apply to the Executive (and the Company shall cooperate in good faith in the valuation of any such services, including any non-competition provisions), and shall make all determinations in accordance with standard accounting and tax principles. The following terms shall have the following meanings for purposes of this Section: (1) a “Payment” shall mean any payment or distribution in the nature of compensation (within the meaning of Section 280G(b)(2) of the Code) to or for the benefit of the Executive, whether paid or payable pursuant to this Agreement or otherwise; (2) “Net After-Tax Receipt” shall mean the Present Value of a Payment net of all taxes imposed on the Executive with respect thereto under Sections 1 and 4999 of the Code and under applicable state and local laws, determined by applying the highest marginal rate under Section 1 of the Code and under state and local laws which applied to the Executive’s taxable income for the immediately preceding taxable year, or such other rate(s) as the Executive shall certify, in the Executive’s sole discretion, as likely to apply to the Executive in the relevant tax year(s); (3) “Accounting Firm” shall mean Golden Parachute Tax Solutions LLC or such other nationally recognized accounting firm mutually selected by the Company and the Executive, which firm shall not be the auditor for the Company or providing services to an acquirer; (4) “Present Value” of a Payment shall mean the present value as of the date of the change of control for purposes of Section 280G of the Code of the portion of such Payment that constitutes a “parachute payment” under Section 280G(b)(2), as determined by the Accounting Firm for purposes of determining whether and to what extent the excise tax under Section 4999 of the Code will apply to such Payment; and (5) “Reduced Amount” shall mean the amount of Payments that (x) has a Present Value that is less than the Present Value of all Payments and (y) results in aggregate Net After-Tax Receipts for all Payments that are greater than the Net After-Tax Receipts for all Payments that would result if the aggregate Present Value of Payments were any other amount that is less than the Present Value of all Payments.
