W I T N E S S E T H: WHEREAS, the Company and its subsidiaries are engaged in the business of providing professional and technical services; and WHEREAS, the Executive is currently employed by the Company as the Chief Executive Officer and President of the Company, and the Company desires to continue the employment of the Executive and secure for the Company the experience, ability and services of the Executive; and WHEREAS, the Executive desires to continue his employment with the Company, pursuant to the terms and conditions herein set forth, superseding all prior oral and written employment agreements, and term sheets and letters between the Company, its subsidiaries and/or predecessors and Executive; NOW, THEREFORE, it is mutually agreed by and between the parties hereto as follows: ARTICLE I DEFINITIONS 1.1 Accrued Compensation. “Accrued Compensation” shall mean an amount which shall include all amounts earned or accrued through the Termination Date (as defined below) but not paid as of the Termination Date, including (a) Base Salary, (b) reimbursement for business expenses incurred by the Executive on behalf of the Company, pursuant to the Company’s expense reimbursement policy in effect at such time, (c) vacation pay, and (d) unpaid bonuses and incentive compensation earned and awarded prior to the Termination Date. 1.2 Cause. “Cause” shall mean: (a) willful disobedience by the Executive of a material and lawful instruction of the Board of Directors of the Company; (b) the Executive’s indictment for, conviction of, or plea of guilty or nolo contendere to any crime involving fraud, embezzlement, bribery, kickback, theft or dishonesty, or any felony; (c) conduct amounting to fraud, dishonesty, gross negligence, willful misconduct, embezzlement or misappropriation of Company assets; (d) failure to substantially perform his duties hereunder, other than during any period of illness or Disability; (e) personally or on behalf of another Person, willfully receiving a benefit relating to the Company or its Subsidiaries or its funds, properties, opportunities, or other assets in violation of applicable law, or constituting fraud, embezzlement, or misappropriation; (f) the knowing misstatement by Executive of the financial records of the Company or its Subsidiaries or complicit actions in respect thereof; or (g) the material breach by Executive of any of the terms of Articles III, VI, or VII, or Sections 4.1 or 4.7 of this Agreement. Notwithstanding the foregoing, however, the Company shall not have the right to terminate the employment of Executive pursuant to the

27669683.v1 2 foregoing clauses (a) and (c) through (g) above unless written notice specifying such breach shall have been given to the Executive and, in the case of breach which is capable of being cured, the Executive shall have failed to cure such breach within thirty (30) days after his receipt of such notice. 1.3 Change in Control. A “Change in Control” shall mean any of the following events: (a) (i) An acquisition (other than directly from the Company) of any voting securities of the Company (the “Voting Securities”) by any “Person” (as the term person is used for purposes of Section 13(d) or 14(d) of the Securities Exchange Act of 1934, as amended (the “1934 Act”)) immediately after which such Person has “Beneficial Ownership” (within the meaning of Rule 13d-3 promulgated under the 1934 Act) of forty-nine percent (49%) or more of the combined voting power of the Company’s then outstanding Voting Securities; provided, however, that in determining whether a Change in Control has occurred, Voting Securities which are acquired in a “Non-Control Acquisition” (as defined below) shall not constitute an acquisition which would cause a Change in Control. A “Non-Control Acquisition” shall mean an acquisition by (1) an employee benefit plan (or a trust forming a part thereof) maintained by (x) the Company or (y) any corporation or other Person of which a majority of its voting power or its equity securities or equity interest is owned directly or indirectly by the Company (a “Subsidiary”), or (2) the Company or any Subsidiary. (ii) Notwithstanding the foregoing, a Change in Control shall not be deemed to occur solely because a Person (the “Subject Person”) gained Beneficial Ownership of more than the permitted amount of the outstanding Voting Securities as a result of the acquisition of Voting Securities by the Company which, by reducing the number of Voting Securities outstanding, increases the proportional number of shares Beneficially Owned by the Subject Person, provided that if a Change in Control would occur (but for the operation of this sentence) as a result of the acquisition of Voting Securities by the Company, and after such share acquisition by the Company, the Subject Person becomes the Beneficial Owner of any additional Voting Securities which increases the percentage of the then outstanding Voting Securities Beneficially Owned by the Subject Person, then a Change in Control shall occur. (b) The individuals who, as of the date this Agreement is approved by the Board, are members of the Board (the “Incumbent Board”), cease for any reason to constitute at least two-thirds of the Board; provided, however, that if the election, or nomination for election by the Company’s stockholders, of any new director was approved by a vote of at least two-thirds of the Incumbent Board, such new director shall, for purposes of this Agreement, be considered and defined as a member of the Incumbent Board; and provided, further, that no individual shall be considered a member of the Incumbent Board if such individual initially assumed office as a result of either an actual “Election Contest” (as described in Rule 14a-11 promulgated under the 1934 Act) or other solicitation of proxies or consents by or on behalf of a Person other than the Board (a “Proxy Contest”); or (c) Consummation by the Company of:

(d) Notwithstanding anything contained in this Agreement to the contrary, if the Employee’s employment is terminated prior to a Change in Control and the Executive reasonably demonstrates that such termination (i) was at the request of a third party who has indicated an intention or taken steps reasonably calculated to effect a Change in Control (a “Third Party”) or (ii) otherwise occurred in connection with, or in anticipation of, a Change in Control, then for all purposes of this Agreement, the date of a Change in Control with respect to the Executive shall mean the date immediately prior to the date of such termination of the Executive’s employment. 1.4 Continuation Benefits. “Continuation Benefits” shall be the continuation of the Benefits, as defined in Section 5.1, for the period commencing on the Termination Date and terminating 18 months thereafter (the “Continuation Period”) at the Company’s expense on behalf of the Executive and his dependents, by payment of Executive’s COBRA premiums or otherwise; provided, however, that (a) any COBRA continuation benefit shall expire at an earlier date as provided by COBRA and (b) the level and availability of benefits provided during the Continuation Period shall at all times be subject to the post-employment conversion or portability provisions of the benefit plans. The Company’s obligation hereunder with respect to the foregoing benefits shall also be limited to the extent that if the Executive obtains any such benefits pursuant to a subsequent employer’s benefit plans, the Company may reduce the coverage of any benefits it is required to provide the Executive hereunder as long as the aggregate coverage and benefits of the combined benefit plans is no less favorable to the Executive than the coverage and benefits required to be

27669683.v1 4 provided hereunder.

Notwithstanding the foregoing, however, the Executive agrees not to terminate his employment for Good Reason pursuant to this Section 1.6 unless (i) the Executive has given the Company at least 30 days’ prior written notice of his intent to terminate his employment for Good Reason, which notice shall specify the facts and circumstances constituting Good Reason; and (ii) the Company has not remedied such facts and circumstances constituting Good Reason to the reasonable and good faith satisfaction of the Executive within a 30-day period after receipt of such notice. 1.7 Notice of Termination.

27669683.v1 7 of which shall be 365 (or 366 in a leap year)), commencing as of the Effective Date, subject to such increases, if any, as determined by the Board, or if the Board so designates, the Management Resources and Compensation Committee (the “Committee”), at the commencement of each of the Company’s fiscal years during the term of this Agreement (the “Base Salary”). The Committee shall review the Executive’s compensation at least once per year and effect such increases in the Base Salary as the Committee, in its sole discretion, determines are merited, based upon the Executive’s performance and consistent with the Company’s compensation policies. 4.2 The Base Salary shall be paid to the Executive in accordance with the Company’s regular executive payroll periods. 4.3 For each fiscal year during the Employment Period, Executive shall be eligible to participate in the Company’s annual incentive bonus program.

At the commencement of each fiscal year, the Committee or the Board shall establish and communicate to the Executive the performance targets and other key objectives for the Company and/or the Executive (the “Performance Criteria”) and the formula(s) for determining the Annual Bonus, if any, that may be earned by the Executive.

Any awards granted under such Long-Term Incentive Plan shall be subject to the terms of the

27669683.v1 8 applicable Long-Term Incentive Plan and the applicable award agreements in the form acceptable to the Board or Committee and such other terms as may be established by the Board or Committee. 4.6 Executive may receive such other additional compensation as may be determined from time to time by the Board of Directors or Committee including bonuses and other long-term compensation plans. Nothing herein shall be deemed or construed to require the Board of Directors or Committee to award any bonus or additional compensation. 4.7 Notwithstanding any other provisions in this Agreement to the contrary, the Executive agrees and acknowledges that any incentive-based compensation, or any other compensation, paid or payable to Executive pursuant to this Agreement or any other agreement or arrangement with the Company shall be subject to recoupment or clawback under applicable law, government regulation, or stock exchange listing requirement, including without limitation, the Dodd-Frank Wall Street Reform and Consumer Protection Act and such regulations as may be promulgated thereunder by the Securities and Exchange Commission and the principal exchange on which the Company’s securities are listed for trading, including Rule 5608 of the Nasdaq Listing Rules.

ARTICLE VI NON-DISCLOSURE

27669683.v1 9 6.1 The Executive shall not, at any time during or after the termination of his employment hereunder, except when acting on behalf of and with the authorization of the Company, make use of or disclose to any person, corporation, or other entity, for any purpose whatsoever, any trade secret or other confidential information concerning the Company’s business, finances, marketing, accounting, personnel and/or staffing business of the Company and its subsidiaries, including information relating to any customer of the Company or pool of temporary or permanent employees, governmental customer or any other nonpublic business information of the Company and/or its subsidiaries learned as a consequence of Executive’s employment with the Company (collectively referred to as the “Proprietary Information”). For the purposes of this Agreement, trade secrets and confidential information shall mean information disclosed to the Executive or known by him as a consequence of her employment by the Company, whether or not pursuant to this Agreement, and not generally known in the industry. The Executive acknowledges that Proprietary Information, trade secrets and other items of confidential information, as they may exist from time to time, are valuable and unique assets of the Company, and that disclosure of any such information would cause substantial injury to the Company. Trade secrets and confidential information shall cease to be trade secrets or confidential information, as applicable, at such time as such information becomes public other than through disclosure, directly or indirectly, by Executive in violation of this Agreement. 6.2 If Executive is requested or required (by oral questions, interrogatories, requests for information or document subpoenas, civil investigative demands, or similar process) to disclose any Proprietary Information, Executive shall, unless prohibited by law, promptly notify the Company of such request(s) so that the Company may seek an appropriate protective order. Notwithstanding the foregoing, Executive understands that nothing contained in this Agreement limits Executive’s ability from reporting possible violations of federal law or regulation to any federal, state or local governmental agency or entity, including but not limited to the Department of Justice, the Securities and Exchange Commission, or any agency Inspector General (“Government Agencies”), or making other disclosures that are protected under the whistleblower provisions of federal law or regulation. Executive further understands that this Agreement does not limit Executive’s ability to communicate with any Government Agencies or otherwise participate in any investigation or proceeding that may be conducted by any Government Agency, including providing documents or other information, without notice to the Company. This Agreement does not limit Executive’s right to receive an award for information provided to any Government Agencies. 6.3 Except as otherwise may be agreed by the Company in writing, in consideration of the employment of Executive by the Company, and free of any additional obligations of the Company to make additional payment to Executive, Executive hereby agrees to irrevocably assign to the Company any and all of Executive’s rights (including patent rights, copyrights, trade secret rights and other rights, throughout the world), title and interest in and to all inventions, software, manuscripts, documentation, improvements or other intellectual property whether or not protectable by any state or federal laws relating to the protection of intellectual property, relating to the present or future business of the Company that are developed by Executive during the term of his/her employment with the Company, either alone or jointly with others, and whether or not developed during normal business hours or arising within the scope of his/her duties of

27669683.v1 10 employment. Executive agrees that all such inventions, software, manuscripts, documentation, improvement or other intellectual property shall be and remain the sole and exclusive property of the Company and shall be deemed the product of work for hire. Executive hereby agrees to execute such assignments and other documents as the Company may consider appropriate to vest all right, title and interest therein to the Company and hereby appoints the Company as Executive’s attorney-in-fact with full powers to execute such document itself in the event Executive fails or is unable to provide the Company with such signed documents. Executive shall also assign to, or as directed by, the Company, all of his right, title and interest in and to any and all inventions and other intellectual property, the full title to which is required to be in the United States government of any of its agencies. The Company shall have all right, title and interest in all research and work product produced by Executive as an employee of the Company, including, but not limited to, all research materials. Notwithstanding the foregoing, this provision does not apply to an invention for which no equipment, supplies, facility, or trade secret information of the Company was used and which was developed entirely on Executive’s own time, unless (a) the invention relates (i) to the business of the Company, or (ii) to the Company’s actual or demonstrably anticipated research or development, or (b) the invention results from any work performed by Executive for the Company. ARTICLE VII RESTRICTIVE COVENANTS 7.1 During the term of Employment with the Company, and for a period of one (1) year following termination of employment for any reason, Executive agrees that he will not, directly or indirectly, enter into or become associated with or engage in any “Competitive Business” (whether as a partner, officer, director, shareholder, employee, consultant, or otherwise), which for the purpose of this Agreement, means a company, business or organization engaged in the same or similar business as the Company in direct competition with the Company during the term of this Agreement or as of the Termination Date, or which the Company was in the process of developing as of the Termination Date, which, for purposes of clarification, includes without limitation, the provision of any program, product, or service that is competitive with programs, products, or services offered by the Company during the term of this Agreement and/or that was the subject of any capture effort, bid, offer or proposal activity by the Company in which the Grantee was personally and substantially involved. Notwithstanding the foregoing, the ownership by Employee of less than five percent of the shares of any publicly held corporation shall not violate the provisions of this Article VII. 7.2 In furtherance of, and in addition to, Section 7.1, during the period of non- competition specified in Section 7.1 (the “Restricted Period”), Executive shall not during the Restricted Period, directly or indirectly, whether as a principal, agent, employee, independent contractor, employer, partner or shareholder, in connection with or related to any Competitive Business, solicit (a) any actual customers, partners or contracts addressed by the Company during the tenure of Executive’s employment or (b) any customers, partners or contracts that were within the Company’s business development pipeline within the twelve month period ending on the effective date of the termination of employment, unless otherwise agreed to by the Company in writing.

27669683.v1 11 solicit, hire, attempt to solicit or hire, or participate in any attempt to solicit or hire, any person who is employed by the Company or retained as a consultant by the Company (or who was employed or retained by the Company within 12 months of the Termination Date or who was being actively recruited by the Company) to: (A) terminate his employment or engagement with the Company; (B) accept employment or engagement with anyone other than the Company, or (C) in any manner interfere with the business of the Company, unless otherwise agreed to by the Company in writing. 7.3 Executive hereby acknowledges that the covenants and agreements contained in Article VI and Article VII of this Agreement (the “Restrictive Covenants”) are reasonable and valid in all respects and that the Company is entering into this Agreement, inter alia, on such acknowledgement. If Executive breaches, or threatens to commit a breach, of any of the Restrictive Covenants, the Company shall have the following rights and remedies, each of which rights and remedies shall be independent of the other and severally enforceable, and all of which rights and remedies shall be in addition to, and not in lieu of, any other rights and remedies available to the Company under law or in equity: (a) the right and remedy to have the Restrictive Covenants specifically enforced by any court having competent jurisdiction, it being acknowledged and agreed that any such breach or threatened breach may cause irreparable injury to the Company and that money damages may not provide an adequate remedy to the Company; (b) the right and remedy to require Executive to account for and pay over to the Company such damages as are recoverable at law as the result of any transactions constituting a breach of any of the Restrictive Covenants; (c) if any court determines that any of the Restrictive Covenants, or any part thereof, is invalid or unenforceable, the remainder of the Restrictive Covenants shall not thereby be affected and shall be given full effect, without regard to the invalid portions; and (d) if the court construes any of the Restrictive Covenants, or any part thereof, to be unenforceable because of the duration of such provision or the area covered thereby, such court shall have the power to reduce the duration or area of such provision and, in its reduced form, such provision shall then be enforceable and shall be enforced. ARTICLE VIII TERM 8.1 This Agreement shall be for a term (the “Initial Term”) commencing on the Effective Date as set forth above and terminating on September 30, 2028, unless sooner terminated as otherwise provided herein. 8.2 Unless this Agreement is earlier terminated pursuant to the terms hereof, upon expiration of the Initial Term, this Agreement and the term of the Executive’s employment shall automatically be extended for consecutive periods of one (1) year each (each such renewal period, a “Renewal Term”), unless a Notice of Termination of employment is given by either party hereto at least ninety (90) days prior to the expiration of the Initial Term or any Renewal Term, in which case, this Agreement shall terminate at the end of such Initial Term or Renewal Term, as the case may be.

Notwithstanding the foregoing, however, if Executive’s termination, giving rise to a right to Severance Payment and Continuation Benefits, occurs after March 15th of a given year, the payments of the Severance Payment and any payments for Continuation Benefits shall be accelerated to complete payment before March 15th of the year following termination if necessary to comply with the short term deferral exception under Section 409A of the Code to conform with the intent of Section 12.1 of this Agreement. The parties agree that if any such provision is subject to more than one interpretation or construction, such ambiguity shall be resolved in favor of that interpretation or construction which is consistent with such provisions not being subject to the provisions of Section 409A. 9.5 Notwithstanding the foregoing, the payment of any and all compensation due hereunder, except Accrued Compensation and Executive’s right to exercise any vested employee Stock Options after the Termination Date, is expressly conditioned on (i) in the event Employee is a member of the Board of Directors on the Termination Date, Executive’s resignation from the Board of Directors of the Company and with any Subsidiary of the Company, within five (5) business days of notice by the Company requesting such resignation, (ii) Executive’s execution (and not revoking) a general release and waiver of claims against the Company in a form reasonably acceptable to the Executive and the Company, and (iii) full and continued compliance by Executive with the covenants and obligations described in Article VI and Article VII of this Agreement. 9.6 The Executive shall not be required to mitigate the amount of any payment provided for in this Agreement by seeking other employment or otherwise and no such payment shall be offset or reduced by the amount of any compensation or benefits provided to the Executive in any subsequent employment except as provided in Section 1.4. 9.7 Upon termination of Executive’s employment, except for the payments required by Section 9.3 or as required by applicable law, the Company will have no additional obligations to Executive hereunder or otherwise and, except as otherwise provided in this Agreement (including but not limited to Executive’s obligations under Article VI and Article VII herein), this Agreement will terminate. 9.8 In the event that the Company becomes obligated during the term of this Agreement to make post-termination payments to Executive pursuant to this Article IX, the Company’s obligation to continue to make such payments in accordance with this Article IX shall survive the termination of the Agreement, subject to the other provisions of this Agreement (including but not limited to Executive’s compliance with Articles VI and VII). For the avoidance of doubt, Executive will not be entitled to any payments pursuant to this Article IX if the termination of Executive’s employment occurs after the expiration or earlier termination of this Agreement. ARTICLE X

27669683.v1 14 EQUITY AND LONG-TERM INCENTIVE AWARDS 10.1 During the term of this Agreement, Executive shall be eligible to receive equity or performance awards, subject to the approval of the Committee, payable in shares of stock, restricted stock units, stock options, stock or cash-based performance awards, cash, or other vehicles pursuant to and allowed under any long-term incentive compensation plan adopted by the Committee or the Board. Equity and long-term incentive awards (“together, “LTI Awards”) shall be granted under the Company’s 2025 Equity Incentive Plan or such other long-term incentive compensation plan as may be adopted by the Company. The actual grant date value of any such LTI awards shall be determined in the discretion of the Committee or Board and any such awards shall include such vesting conditions and other terms and conditions as determined by the Committee or the Board. Notwithstanding the foregoing, however, the target value of such LTI Award opportunity will not be less than two hundred and fifty percent (250%) of the Executive’s annual Base Salary as of the grant date for the first incentive award which may be granted to Executive during the first year of this Agreement. As part of the Committee’s annual review of the Executive’s compensation, the Committee may, in its discretion, award additional LTI Awards to the Executive based upon the Executive’s and the Company’s performance and consistent with the Company’s equity compensation policies. 10.2 In the event that either (i) Executive’s employment is terminated due to his Disability or death or (ii) within one hundred and eighty (180) days of a Change in Control, either the Executive’s employment is terminated by the Company without Cause or the Executive terminates this Agreement and resigns employment for Good Reason, then (a) following the Executive’s date of termination and subject to the conditions of Section 9.5, each unexpired option presently outstanding and held by Executive, and unless expressly determined otherwise by the Management Resources and Compensation Committee, each unexpired option to purchase shares of Common Stock of the Company granted to Executive after the date hereof, shall immediately vest and be exercisable in full and the exercise period in which Executive may exercise all such options shall be extended to the duration of their original term, and the terms of all such options shall be deemed amended to take into account the foregoing provisions; and (b) unless expressly determined otherwise by the Management Resources and Compensation Committee, subject to the conditions of Section 9.5, each other unexpired equity compensation award or other LTI Award, including restricted stock or stock unit awards held by the Executive (whether equity- or cash- based), shall be deemed to be fully vested and free from repurchase and forfeiture provisions, and, to the extent applicable, will no longer be subject to a right of repurchase by or forfeiture to the Company; provided that the vesting will not accelerate the distribution of shares underlying equity awards if such acceleration of distribution would trigger taxation under Section 409A of the Code. 10.3 In the event Executive’s employment was terminated by the Company without Cause or the Executive terminates this Agreement and resigns employment for Good Reason, and such termination is not within the one-hundred eighty (180) day period of a Change in Control, then,

27669683.v1 15 (a) following the Executive’s date of termination and subject to the conditions of Section 9.5, each unexpired option presently outstanding and held by Executive that is subject only to time-based vesting conditions and each unexpired option to purchase shares of Common Stock of the Company granted to Executive after the date hereof that is subject only to time-based vesting conditions, shall immediately vest and be exercisable in full and the exercise period in which Executive may exercise all such options shall be extended to the duration of their original term, and the terms of all such options shall be deemed amended to take into account the foregoing provisions; and (b) subject to the conditions of Section 9.5, each other unexpired equity compensation award or other LTI Award that is subject only to time-based vesting conditions (whether equity- or cash- based), including restricted stock or stock unit awards held by the Executive, shall be deemed to be fully vested and free from repurchase and forfeiture provisions, and, to the extent applicable, will no longer be subject to a right of repurchase by or forfeiture to the Company; provided that the vesting will not accelerate the distribution of shares underlying equity awards if such acceleration of distribution would trigger taxation under Section 409A of the Code. ARTICLE XI EXTRAORDINARY TRANSACTIONS 11.1 The Company’s Board of Directors has determined that it is appropriate to reinforce and encourage the continued attention and dedication of members of the Company's management, including the Executive, to their assigned duties without distraction in potentially disturbing circumstances arising from the possibility of a change in control of the Company. 11.2 In the event that within one hundred and eighty (180) days of a Change in Control, Executive is terminated without Cause, or Executive terminates his employment for Good Reason, then, subject to the conditions of Section 9.5, the Company shall pay and/or provide to the Executive, in addition to the provisions of Section 10.2, above, the following compensation and benefits, in lieu of any other payments due hereunder: (i) the Accrued Compensation; (ii) the Continuation Benefits; and (iii) a lump sum payment within ten (10) days of the Termination Date equal to 250% of the Executive’s Base Salary in effect on the effective date of the Change in Control. 11.3 Notwithstanding the foregoing, if the payment under this Article XI, either alone or together with other payments which the Executive has the right to receive from the Company, would constitute an “excess parachute payment” as defined in Section 280G of the Internal Revenue Code of 1986, as amended (the “Code”), the aggregate of such credits or payments under this Agreement and other agreements shall be reduced to the largest amount as will result in no portion of such aggregate payments being subject to the excise tax imposed by Section 4999 of the Code. The priority of the reduction of excess parachute payments shall be in the discretion of the Executive. The Company shall give notice to the Executive as soon as practicable after its determination that Change in Control payments and benefits are subject to the excise tax, but no later than ten (10) days in advance of the due date of such Change in Control payments and

27669683.v1 16 benefits, specifying the proposed date of payment and the Change in Control benefits and payments subject to the excise tax. Executive shall exercise his option under this Section 11.3 by written notice to the Company within five (5) days in advance of the due date of the Change in Control payments and benefits specifying the priority of reduction of the excess parachute payments. ARTICLE XII SECTION 409A COMPLIANCE 12.1 To the extent applicable, it is intended that any amounts payable under this Agreement shall either be exempt from Section 409A of the Code or shall comply with Section 409A (including Treasury regulations and other published guidance related thereto) so as not to subject Executive to payment of any additional tax, penalty or interest imposed under Section 409A of the Code. The provisions of this Agreement shall be construed and interpreted to the maximum extent permitted to avoid the imputation of any such additional tax, penalty or interest under Section 409A of the Code yet preserve (to the nearest extent reasonably possible) the intended benefit payable to Executive. Notwithstanding the foregoing, the Company makes no representations regarding the tax treatment of any payments hereunder, and the Executive shall be responsible for any and all applicable taxes, other than the Company’s share of employment taxes on the severance payments provided by the Agreement. Executive acknowledges that Executive has been advised to obtain independent legal, tax or other counsel in connection with Section 409A of the Code. 12.2 Notwithstanding any provisions of this Agreement to the contrary, if Executive is a “specified employee” (within the meaning of Section 409A of the Code and the regulations adopted thereunder) at the time of Executive’s separation from service and if any portion of the payments or benefits to be received by Executive upon separation from service would be considered deferred compensation under Section 409A of the Code and the regulations adopted thereunder (“Nonqualified Deferred Compensation”), amounts that would otherwise be payable pursuant to this Agreement during the six-month period immediately following Executive’s separation from service that constitute Nonqualified Deferred Compensation and benefits that would otherwise be provided pursuant to this Agreement during the six-month period immediately following Executive’s separation from service that constitute Nonqualified Deferred Compensation will instead be paid or made available on the earlier of (i) the first business day of the seventh month following the date of Executive’s separation from service and (ii) Executive’s death. Notwithstanding anything in this Agreement to the contrary, distributions upon termination of Executive’s employment shall be interpreted to mean Executive’s “separation from service” with the Company (as determined in accordance with Section 409A of the Code and the regulations adopted thereunder). Each payment under this Agreement shall be regarded as a “separate payment” and not of a series of payments for purposes of Section 409A of the Code. 12.3 Except as otherwise specifically provided in this Agreement, if any reimbursement to which the Executive is entitled under this Agreement would constitute deferred compensation subject to Section 409A of the Code, the following additional rules shall apply: (i) the reimbursable expense must have been incurred, except as otherwise expressly provided in this Agreement, during the term of this Agreement; (ii) the amount of expenses eligible for

27669683.v1 17 reimbursement during any taxable year will not affect the amount of expenses eligible for reimbursement in any other taxable year; (iii) the reimbursement shall be made as soon as practicable after Executive’s submission of such expenses in accordance with the Company’s policy, but in no event later than the last day of Executive’s taxable year following the taxable year in which the expense was incurred; and (iv) the Executive’s entitlement to reimbursement shall not be subject to liquidation or exchange for another benefit. ARTICLE XIII ARBITRATION AND INDEMNIFICATION 13.1 Any controversy, dispute or claim arising out of or relating to this Agreement or breach thereof, with the sole exception of any claim, breach, or violation arising under Articles VI or VII hereof, shall be shall first be settled through good faith negotiation. If the dispute cannot be settled through negotiation, the parties agree to attempt in good faith to settle the dispute by mediation administered by JAMS. If the parties are unsuccessful at resolving the dispute through mediation, the parties agree to final and binding arbitration before a single arbitrator in the State of Georgia in accordance with the Rules of the American Arbitration Association (the “Association”). The arbitrator shall be selected by the mutual agreement of the Company and the Executive; provided, if the Company and Executive do not agree on the appointment of an arbitrator within fifteen calendar days from the date either party seeks to commence arbitration, the parties agree to the appointment of an Arbitrator by the Association in accordance with its Commercial Rules. Any judgment upon any arbitration award may be entered in any court, federal or state, having competent jurisdiction of the parties. 13.2 The Company hereby agrees to indemnify, defend, and hold harmless the Executive for any and all claims arising from or related to his employment by the Company at any time asserted, at any place asserted, to the fullest extent permitted by law, except for claims based on Executive’s fraud, deceit or willfulness. The Company shall maintain such insurance as is necessary and reasonable to protect the Executive from any and all claims arising from or in connection with his employment by the Company during the term of Executive’s employment with the Company and for a period of six (6) years after the date of termination of employment for any reason. The provisions of this Section 13.2 are in addition to and not in lieu of any indemnification, defense or other benefit to which Executive may be entitled by statute, regulation, common law or otherwise. ARTICLE XIV SEVERABILITY 14.1 If any provision of this Agreement shall be held invalid and unenforceable, the remainder of this Agreement shall remain in full force and effect. If any provision is held invalid or unenforceable with respect to particular circumstances, it shall remain in full force and effect in all other circumstances. ARTICLE XV NOTICE
