(i)A “change in the ownership of the Company” which will occur on the date that any one person, or more than one person acting as a group, acquires ownership of stock in the Company that, together with stock held by such person or group, constitutes more than 50% of the total fair market value or total voting power of the stock of the Company; however, if any one person or more than one person acting as a group, is considered to own more than 50% of the total fair market value or total voting power

of the stock of the Company, the acquisition of additional stock by the same person or persons will not be considered a “change in the ownership of the Company” (or to cause a “change in the effective control of the Company” within the meaning of Section 1.1(d)(ii) below) and an increase of the effective percentage of stock owned by any one person, or persons acting as a group, as a result of a transaction in which the Company acquires its stock in exchange for property will be treated as an acquisition of stock for purposes of this paragraph; provided, further, however, that for purposes of this Section 1.1(d)(i), the following acquisitions will not constitute a Change in Control: (A) any acquisition by any employee benefit plan (or related trust) sponsored or maintained by the Company or any entity controlled by the Company or (B) any acquisition by investors (immediately prior to such acquisition) in the Company for financing purposes, as determined by the Committee in its sole discretion. This Section 1.1(d)(i) applies only when there is a transfer of the stock of the Company (or issuance of stock) and stock in the Company remains outstanding after the transaction.

(ii)A “change in the effective control of the Company” which will occur on the date that either (A) any one person, or more than one person acting as a group, acquires (or has acquired during the 12 month period ending on the date of the most recent acquisition by such person or persons) ownership of stock of the Company possessing 35% or more of the total voting power of the stock of the Company, except for (y) any acquisition by any employee benefit plan (or related trust) sponsored or maintained by the Company or any entity controlled by the Company or (z) any acquisition by investors (immediately prior to such acquisition) in the Company for financing purposes, as determined by the Committee in its sole discretion or (B) a majority of the members of the Board are replaced during any 12‑month period by directors whose appointment or election is not endorsed by a majority of the members of the Board prior to the date of the appointment or election. For purposes of a “change in the effective control of the Company,” if any one person, or more than one person acting as a group, is considered to effectively control the Company within the meaning of this Section 1.1(d)(ii), the acquisition of additional control of the Company by the same person or persons is not considered a “change in the effective control of the Company,” or to cause a “change in the ownership of the Company” within the meaning of Section 1.1(d)(i) above.

(iii)A “change in the ownership of a substantial portion of the Company’s assets” which will occur on the date that any one person, or more than one person acting as a group, acquires (or has acquired during the 12 month period ending on the date of the most recent acquisition by such person or persons) assets of the Company that have a total gross fair market value equal to or more than 40% of the total gross fair market value of all the assets of the Company immediately prior to such acquisition or acquisitions. For this purpose, gross fair market value means the value of the assets of the Company, or the value of the assets being disposed of, determined without regard to any liabilities associated with such assets. Any transfer of assets to an entity that is controlled by the shareholders of the Company immediately after the transfer, as provided in guidance issued pursuant to the Nonqualified Deferred Compensation Rules, will not constitute a Change in Control.

For purposes of this Section 1.1(d), the provisions of section 318(a) of the Code regarding the constructive ownership of stock will apply to determine stock ownership; provided that stock underlying unvested options (including options exercisable for stock that is not substantially vested) will not be treated as owned by the individual who holds the option. In addition, for purposes of this Section 1.1(d) and except as otherwise provided in an Award agreement, “Company” includes (x) the Company; (y) the entity for whom the Key Employee performs services; and (z) an entity that is a stockholder owning more than 50% of the total fair market value and total voting power (a “Majority Shareholder”) of the Company or the entity identified in (y) above, or any entity in a chain of entities in which each entity is a Majority Shareholder of another entity in the chain, ending in the Company or the entity identified in (y) above.

(e)“Code” means the Internal Revenue Code of 1986, as amended.

(f)“Disability” means a Key Employee’s disability within the meaning of the Company’s long-term disability plan. In the event of a dispute between the parties as to whether the Key Employee is disabled, whether Key Employee is disabled will be determined by the mutual agreement of a physician selected by the Company or its insurers (the “Company Physician”) and a physician selected by Key Employee (“Key Employee’s Physician”). In the event that the Company Physician and Key Employee’s Physician cannot agree on whether Key Employee is Disabled, such determination will be made by a third physician who is jointly selected by the Company Physician and Key Employee’s Physician.

(g)“Good Reason” means:

(i)a material breach of Section 2.3, including but not limited to reduction of any component of Key Employee’s compensation set forth in Section 2.3(a) or (b) without Key Employee’s consent; provided, however, that a reduction of Key Employee’s compensation set forth in Section 2.3(b) with respect to bonus shall mean the elimination of Key Employee’s ability to earn a bonus or a reduction in the percentage of Base Salary Key Employee is eligible to earn as a bonus,

The waiver and release document must be executed and delivered to the appropriate Company representative on or before the fiftieth day period immediately following Key Employee’s termination of employment.

8.Non‑Competition, Confidentiality.

(a)Agreement not to Compete. In consideration of the Company’s promise to provide Key Employee with Confidential Information, as defined in Section 3.8(b), the other mutual promises contained in this Agreement, and Key Employee’s employment with the Company, and so as to enforce Key Employee’s promises regarding Confidential Information contained in Section 3.8(b) of this Agreement, Key Employee agrees that in the event his employment with the Company is terminated for any reason whatsoever, Key Employee will not, during the applicable Restricted Period (extended by any period of time during which Key Employee is in violation of this Section 3.8), directly or indirectly, carry on or conduct, in competition with the Company or its subsidiaries or affiliates, any business of the nature in which the Company or its subsidiaries or affiliates are then engaged in any geographical area in which the Company or its subsidiaries or affiliates engage in business at the time of such termination or in which any of them, prior to termination of Key Employee’s employment, evidenced in writing, at any time during the six month period prior to such termination, an intention to engage in such business. Key Employee agrees that he will not so conduct or engage in any such business either as an individual on his own account or as a partner or joint venturer or as an Key Employee, agent, consultant or salesman for any other person or entity, or as an officer or director of a corporation or as a shareholder in a corporation of which he will then own 10% or more of any class of stock.

(b)Confidential Information. The Company makes a binding promise not conditioned upon continued employment to provide Key Employee with certain Confidential Information above and beyond any Confidential Information Key Employee may have previously received. Key Employee will not, directly or indirectly, at any time following termination of his employment with the Company, reveal, divulge or make known to any person or entity, or use for Key Employee’s personal benefit (including, without limitation, for the purpose of soliciting business, whether or not competitive with any business of the Company or any of its subsidiaries or affiliates), any information acquired during the Employment Period with regard to the financial, business or other affairs of the Company or any of its subsidiaries or affiliates (including, without limitation, any list or record of persons or entities with which the Company or any of its subsidiaries or affiliates has any dealings), other than (i) information already in the public domain; (ii) information of a type not considered confidential by persons engaged in the same business or a business similar to that conducted by the Company or its subsidiaries and affiliates; or (iii) information that Key Employee is required to disclose under the following circumstances: (A) at the express direction of any authorized governmental entity; (B) pursuant to a subpoena or other court process; (C) as otherwise required by law or the rules, regulations, or orders of any applicable regulatory body; or (D) as otherwise necessary, in the opinion of counsel for Key Employee, to be disclosed by Key Employee in connection with any legal action or proceeding involving Key Employee and the Company or any subsidiary or affiliate of the Company in his capacity as an employee, officer, director, or stockholder of the Company or any subsidiary or affiliate of the Company. Key Employee will, at any time requested by the Company (either during or within two years after his employment with the Company), promptly deliver to the Company all memoranda, notes, reports, lists and

other documents (and all copies thereof) relating to the business of the Company or any of its subsidiaries and affiliates which he may then possess or have under his control.

(c)Reasonableness of Restrictions. Key Employee acknowledges that the geographic boundaries, scope of prohibited activities, and time duration set forth in this Section 3.8 are reasonable in nature and are no broader than are necessary to maintain the confidentiality and the goodwill of the Company and the confidentiality of its Confidential Information and to protect the legitimate business interests of the Company, and that the enforcement of such provisions would not cause Key Employee any undue hardship nor unreasonably interfere with Key Employee’s ability to earn a livelihood. If any court determines that any portion of this Section 3.8 is invalid or unenforceable, the remainder of this Section 3.8 will not thereby be affected and will be given full effect without regard to the invalid provisions. If any court construes any of the provisions of this Section 3.8, or any part thereof, to be unreasonable because of the duration or scope of such provision, such court will have the power to reduce the duration or scope of such provision and to enforce such provision as so reduced.

(d)Enforcement. Upon Key Employee’s employment with an entity that is not a subsidiary or affiliate of the Company (a “Successor Employer”) during the period that the provisions of this Section 3.8 remain in effect, Key Employee will provide such Successor Employer with a copy of this Agreement and will notify the Company of such employment within 30 days thereof. Key Employee agrees that in the event of a breach of the terms and conditions of this Section 3.8 by Key Employee, the Company will be entitled, if it so elects, to institute and prosecute proceedings, either in law or in equity, against Key Employee, to obtain damages for any such breach, or to enjoin Key Employee from any conduct in violation of this Section 3.8.

9.Parachute Payments. Notwithstanding anything to the contrary in this Agreement, if Key Employee is a “disqualified individual” (as defined in Section 280G(c) of the Code), and the benefits provided for in this ARTICLE III, together with any other payments and benefits which Key Employee has the right to receive from the Company would constitute a “parachute payment” (as defined in Section 280G(b)(2) of the Code), then the benefits provided hereunder (beginning with any benefit to be paid in cash hereunder) will be reduced (but not below zero) so that the present value of such total amounts and benefits received by Key Employee will be $1.00) less than three times Key Employee’s “base amount” (as defined in Section 280G(b)(3) of the Code) and so that no portion of such amounts and benefits received by Key Employee will be subject to the excise tax imposed by Section 4999 of the Code. The determination as to whether such a reduction in the amount of the benefits provided hereunder is necessary will be made by the Board in good faith. If a reduced cash payment is made and through error or otherwise that payment, when aggregated with other payments and benefits from the Company used in determining if a “parachute payment” exists, exceeds $1.00 less than three times the Key Employee’s base amount, then Key Employee will immediately repay such excess to the Company upon notification that an overpayment has been made. Nothing in this Section 3.9 will require the Company to be responsible for, or have any liability or obligation with respect to, Key Employee’s excise tax liabilities under Section 4999 of the Code.

10.Payments Subject to Section 409A of the Code. Notwithstanding any provision of this Agreement to the contrary, all provisions of this Agreement are intended to comply with Section 409A of the Code and the applicable Treasury regulations and administrative guidance issued thereunder (collectively, “Section 409A”) or an exemption therefrom and shall be construed and administered in accordance with such intent. Any payments under this Agreement that may be excluded from Section 409A either as separation pay due to an involuntary separation from service or as a short-term deferral shall be excluded from Section 409A to the maximum extent possible. For purposes of Section 409A, each installment payment provided under this Agreement shall be treated as a separate payment. Any payments to be made under this Agreement upon a termination of Key Employee’s employment shall only be made if such termination of employment constitutes a “separation from service” under Section 409A. To the extent that any right to reimbursement of expenses or payment of any benefit in-kind under this Agreement constitutes nonqualified deferred compensation (within the meaning of Section 409A), (a) any such expense reimbursement shall be made by

the Company no later than the last day of the taxable year following the taxable year in which such expense was incurred by Key Employee, (b) the right to reimbursement or in-kind benefits shall not be subject to liquidation or exchange for another benefit, and (c) the amount of expenses eligible for reimbursement or in-kind benefits provided during any taxable year shall not affect the expenses eligible for reimbursement or in-kind benefits to be provided in any other taxable year; provided, that the foregoing clause shall not be violated with regard to expenses reimbursed under any arrangement covered by Section 105(b) of the Code solely because such expenses are subject to a limit related to the period the arrangement is in effect. Notwithstanding any provision in this Agreement to the contrary, if any payment or benefit provided for herein would be subject to additional taxes and interest under Section 409A if Key Employee’s receipt of such payment or benefit is not delayed until the earlier of (x) the date of Key Employee’s death or (y) the date that is six months after the termination of employment (such date, the “Section 409A Payment Date”), then such payment or benefit shall not be provided to Key Employee (or Key Employee’s estate, if applicable) until the Section 409A Payment Date. Notwithstanding the foregoing, the Company makes no representations that the payments and benefits provided under this Agreement are exempt from, or compliant with, Section 409A and in no event shall the Company or any of its affiliates be liable for all or any portion of any taxes, penalties, interest or other expenses that may be incurred by Key Employee on account of non-compliance with Section 409A.
