In the event Employee’s employment is terminated for any other reason, including retirement with the approval of (A) the Committee if Employee is a “senior executive of the Company” (as defined below) or (B) the Company’s Chief Executive Officer (the “CEO”) if Employee is not a senior executive of the Company, the Committee (or its delegate, as appropriate) or, in the event of retirement of an Employee who is not a senior executive of the Company, the CEO, as applicable, may, in the Committee’s (or such delegate’s) or the CEO’s, as applicable, sole discretion, approve the acceleration of the vesting of any or all Restricted Stock Units that have not yet been forfeited and which are still outstanding and subject to restrictions, such vesting acceleration to be effective on the date of such approval or Employee’s termination date, if later.

Payment for vested Restricted Stock Units shall be made as soon as administratively practicable after vesting, but in no event later than thirty days after the vesting date. Settlement will be made in the form of shares of Stock equal in number to the number of Restricted Stock Units with respect to which payment is being made on the applicable date; provided, however, that payment for a vested Restricted Stock Unit shall be made at the time provided above

solely in cash (in lieu of in the form of a share of Stock) in an amount equal to the Fair Market Value as of the vesting date of such Restricted Stock Unit if there are an insufficient number of shares available for delivery under the Plan at the time of such settlement as determined by the Committee or its delegate in the Committee’s or such delegate’s sole discretion. Notwithstanding the foregoing, the Company shall not be obligated to deliver any shares of Stock if counsel to the Company determines that such sale or delivery would violate any applicable law or any rule or regulation of any governmental authority or any rule or regulation of, or agreement of the Company with, any securities exchange or association upon which the Stock is listed or quoted.

10.Non-Competition; Non-Solicitation; Non-Disclosure.

(a)Following the date Employee enters into this Agreement, the Company and/or its Subsidiary(ies) shall provide Employee access to Confidential Information (as defined below). Such Confidential Information shall be for use only during Employee’s employment with the Company, and as an express incentive for the Company to enter into this Agreement and to grant to Employee the Restricted Stock Units (which grant, Employee acknowledges, shall further align Employee’s interests with the long-term business interests of the Company and its Subsidiaries) and provide

Employee with Confidential Information, Employee has voluntarily agreed to the covenants set forth in this Paragraph 10. Employee agrees and acknowledges that the limitations and restrictions set forth herein, including geographical and temporal restrictions on certain competitive activities, are reasonable in all respects, do not interfere with public interests, will not cause Employee undue hardship, and are material and substantial parts of this Agreement intended and necessary to prevent unfair competition and to protect the Company’s and its Subsidiaries’ trade secrets and other Confidential Information, goodwill and legitimate business interests.

(b)During the Prohibited Period (as defined below), Employee shall not, without the prior written approval of the Company, directly or indirectly, for Employee or on behalf of or in conjunction with any other person or entity of any nature:

(i)    engage in or participate within the Market Area (as defined below) in competition with the Company or any of its Subsidiaries in any aspect of the Business (as defined below), which prohibition shall prevent Employee from directly or indirectly: (A) owning, managing, operating, or being an officer or director of, any business that competes with the Company or any of its Subsidiaries in the Market Area, or (B) joining, becoming an employee or consultant of, or otherwise being affiliated with, any person or entity engaged in, or planning to engage in, the Business in the Market Area in competition, or anticipated competition, with the Company or any of its Subsidiaries in any capacity (with respect to this clause (B)) in which Employee’s duties or responsibilities are the same as or similar to the duties or responsibilities that Employee had on behalf of the Company or any of its Subsidiaries, or involve direct or indirect oversight over such duties or responsibilities;

(ii)    appropriate any Business Opportunity of, or relating to, the Company or any of its Subsidiaries located in the Market Area;

(iii)    solicit, canvass, approach, encourage, entice or induce any customer or supplier of the Company or any of its Subsidiaries for whom or which Employee had responsibility in the final 12 months prior to the termination of Employee’s employment with the Company to cease or lessen such customer’s or supplier’s business with the Company or any of its Subsidiaries; or

(iv)    solicit, canvass, approach, encourage, entice or induce any employee or contractor of the Company or any of its Subsidiaries to terminate his, her or its employment or engagement with the Company or any of its Subsidiaries.

(c)Notwithstanding any other provision of this Agreement:

(i)    the covenants set forth in this Paragraph 10 shall not apply to restrict any of Employee’s activities within the State of California, including if Employee is a California resident; and

(ii)    the covenants set forth in Paragraphs 10(b)(i), 10(b)(ii) shall not apply with respect to any activities conducted within Washington, D.C., as such covenants shall not apply with respect to individuals’ performance of work in Washington, D.C.;

provided, however, for the avoidance of doubt, the foregoing exceptions under this Paragraph 10(c) shall not limit any other obligations that Employee owes to the Company or any of its Subsidiaries under any other agreements or applicable laws, including (without limitation) with respect to the protection of Confidential Information.

(d)If Employee is an attorney at law or licensed lawyer in any jurisdiction, none of the restrictions set forth in this Paragraph 10 shall be interpreted or applied in a manner to prevent or restrict Employee from practicing law, as it is the intent of this Paragraph 10 to create certain limitations on Employee’s business activities only, and not to create limitations that would restrict Employee from practicing law. If Employee is an attorney at law or licensed to practice law, Employee acknowledges and agrees that, both during Employee’s employment with the Company and thereafter, Employee shall be bound by all ethical and professional obligations (including those with respect to conflicts of interest and confidentiality) that may arise from Employee’s provision of legal services to, and acting as legal counsel for, the Company and (as applicable) its Subsidiaries.

(e)Employee agrees, both during and after Employee’s employment with the Company, not to use or disclose any Confidential Information other than for the benefit of the Company or its Subsidiaries in the course of Employee’s duties for the Company or its applicable Subsidiary. All trade secrets, non-public information, designs, ideas, concepts, improvements, product developments, discoveries and inventions, whether patentable or not, that are conceived, made, developed or acquired by or disclosed to Employee, individually or in conjunction with others, in connection with Employee’s employment with the Company or otherwise during the time that Employee is or has been employed or engaged by the Company or any of its Subsidiaries (whether during business hours or otherwise and whether on the Company’s or its Subsidiaries’ premises or otherwise), that relate to the Companies’ or its Subsidiaries’ businesses or properties, products or services (including all such information relating to corporate opportunities, operations, future plans, methods of doing business, business plans, formulas, strategies for developing business and market share, research, financial and sales data, pricing terms, evaluations, opinions, interpretations, acquisition prospects, the identity of customers or their requirements, research and development information, the identity of key contacts within customers’ organizations or within the organization of acquisition prospects, or marketing and merchandising techniques, prospective names and marks) is defined as “Confidential Information”. For purposes of this Agreement, Confidential Information shall not include any information that (i) is or becomes generally available to the public other than as a result of a disclosure or wrongful act of Employee or Employee’s agents; (ii) was available to Employee on a non-confidential basis before its disclosure by the Company or any of its Subsidiaries; or (iii) becomes

available to Employee on a non-confidential basis from a source other than the Company or any of its Subsidiaries; provided, that such source is not bound by a confidentiality agreement with, or other obligation with respect to confidentiality to, the Company or any of its Subsidiaries.

(f)Notwithstanding the foregoing Paragraph 10(e), nothing in this Agreement shall prohibit or restrict Employee from lawfully (i) initiating communications directly with, cooperating with, providing information to, causing information to be provided to, or otherwise assisting in an investigation by, any governmental authority (in each instance regarding a possible violation of any law); (ii) responding to any inquiry or legal process directed to Employee from any such governmental authority; (iii) testifying, participating or otherwise assisting in an action or proceeding by any such governmental authority relating to a possible violation of law or (iv) making any other disclosures that are protected under the whistleblower provisions of any applicable law. Additionally, pursuant to the federal Defend Trade Secrets Act of 2016, Employee shall not be held criminally or civilly liable under any federal or state trade secret law for the disclosure of a trade secret that: (x) is made (A) in confidence to a federal, state or local government official, either directly or indirectly, or to an attorney and (B) solely for the purpose of reporting or investigating a suspected violation of law; (y) is made to Employee’s attorney in relation to a lawsuit for retaliation against Employee for reporting a suspected violation of law or (z) is made in a complaint or other document filed in a lawsuit or other proceeding, if such filing is made under seal. Nothing in this Agreement requires Employee to obtain prior authorization before engaging in any conduct described in this paragraph, or to notify the Company or any of its Subsidiaries that Employee has engaged in any such conduct.

(g)Because of the difficulty of measuring economic losses to the Company and its Subsidiaries as a result of a breach or threatened breach of the covenants set forth in this Paragraph 10, and because of the immediate and irreparable damage that would be caused to the Company and its Subsidiaries for which they would have no other adequate remedy, the Company and each of its Subsidiaries shall be entitled to enforce the foregoing covenants, in the event of a breach or threatened breach, by injunctions and restraining orders from any court of competent jurisdiction, without the necessity of showing any actual damages or that money damages would not afford an adequate remedy, and without the necessity of posting any bond or other security. The aforementioned equitable relief shall not be the Company’s or its Subsidiaries’ exclusive remedy for a breach but instead shall be in addition to all other rights and remedies available to the Company and each of its Subsidiaries at law and equity.

(h)The covenants in this Paragraph 10, and each provision and portion hereof, are severable and separate, and the unenforceability of any specific covenant (or portion thereof) shall not affect the provisions of any other covenant (or portion thereof). Moreover, in the event any arbitrator or court of competent jurisdiction shall determine that the scope, time or territorial restrictions set forth are unreasonable, then it is the

intention of the parties that such restrictions be enforced to the fullest extent which such arbitrator or court deems reasonable, and this Agreement shall thereby be reformed.

(i)The following terms shall have the following meanings:

(i)    “Business” shall mean the business and operations that are the same or similar to those performed by the Company and any of its Subsidiaries for which Employee provides services or about which Employee obtains Confidential Information during Employee’s employment with the Company.

(ii)    “Business Opportunity” shall mean any commercial, investment or other business opportunity relating to the Business.

(iii)    “Market Area” shall mean: (i) during that portion of the Prohibited Period that exists during which Employee is employed by the Company, any geographic area or market where Employee provides, or has provided, services to the Company or any of its Subsidiaries; and (ii) during that portion of the Prohibited Period that exists following the date that Employee is no longer employed by the Company, any geographic area or market where Employee provided services to the Company or any of its Subsidiaries as of the date Employee is no longer employed by the Company or during the 12 months prior to such date.

(iv)    “Prohibited Period” shall mean the period during which Employee is employed by the Company and continuing for a period of 12 months following the date that Employee is no longer employed by the Company; provided, however, with respect to a termination of employment with the Company on or after the date upon which a Corporate Change occurs, the Prohibited Period shall end on the date of such termination of employment with respect to the obligations under Paragraphs 10(b)(i) and 10(b)(ii).

11.Section 409A. Notwithstanding anything in this Agreement to the contrary, if any provision in this Agreement would result in the imposition of an applicable tax under Section 409A of the Code and related regulations and United States Department of the Treasury pronouncements (“Section 409A”), that provision will be reformed to avoid imposition of the applicable tax and no action taken to comply with Section 409A shall be deemed to adversely affect Employee’s rights under this Agreement.

IN WITNESS WHEREOF, the Company has caused this Agreement to be duly executed by an officer thereunto duly authorized, and Employee has executed this Agreement, all as of the date first above written.
