2.Payments, Benefits and Perquisites.

Executive agrees to notify Company when he has elected replacement coverage.

3.Other Compensation or Benefits. Executive acknowledges that, except as expressly provided in this Agreement, Executive is not entitled to and will not receive any additional compensation, severance, or benefits from the Company after the Separation Date other than vested compensation or benefits under the Company’s employee benefit plans in accordance with the respective terms thereof.

toward any such claw back. Nothing in this Agreement shall prevent Executive from commencing an action to challenge a termination of his Severance Payments if he believes (i) the Company was not required to claw back his Severance Payments or (ii) the Company terminated the Severance Payments in breach of this Agreement. In addition, nothing in this Agreement shall prevent or waive Executive’s ability or right to contest or defend against any claim made against him for disgorgement, penalties, fines, forfeiture, or the return of any compensation or benefits of any kind in any government inquiry or proceeding or in any litigation brought against the Company or the Executive.

Notwithstanding the foregoing, (a) Executive and his counsel may retain copies of documents relating to this Agreement, his employment relationship with the Company, and his benefits, compensation and equity interests; and (b) Executive’s counsel (and any experts engaged by such counsel) may retain any Company documents provided to such counsel by the Company, by the Executive or by counsel for any party for the purpose of assisting in their defense of Executive in any government inquiries or proceedings or in any litigation brought against the Company or Executive (the “permitted purposes”) and any copies thereof, provided that Executive’s counsel and experts use such Company documents only for the permitted purposes, maintain the confidentiality of such Company documents (including, if they must be filed in court, filing then-I under seal if possible), and return them to the Company when they are no longer needed for the permitted purposes (or, in the case of Company documents reflecting Executive’s attorneys’ work product or attorney-client communications between Executive and his attorneys, certifying their destruction when they are no longer legally required to be maintained), and provided further that Executive and his counsel return to the Company promptly upon request, and share with no other party without the Company’s express written consent, any Company documents containing the Company’s attorney-client privileged information or attorney work product of the Company’s counsel.

6.Proprietary Information and Noncompetition Obligations. Executive acknowledges his continuing obligations under the At-Will Employment, Confidential Information, Invention Assignment and Arbitration Agreement executed by Executive (the

“Confidentiality Agreement”), a copy of which is attached hereto as Exhibit A, including but not limited to, Executive’s obligations related to confidentiality and noninterference with personnel relations. Notwithstanding anything herein or in Exhibit A to the contrary, Executive shall not be held liable under this Agreement, Exhibit A or any other agreement or any federal or state trade secret law for making any confidential disclosure of a Company trade secret or other confidential information to a government official or an attorney for purposes of reporting a suspected violation of law or regulation, or in a court filing under seal.

On the Separation Date or within 21 days thereafter, Executive shall execute the Release Agreement that is attached as Exhibit C (the “Confirming Release”), and return his executed Confirming Release to the Company pursuant to the Notice provision set forth in Section 21 below, so that it is received by Company no later than 21 days after the Separation Date. Executive acknowledges and agrees that this provides sufficient time to consider the Confirming Release, and he has knowingly and voluntarily waived any longer period of time to consider the Confirming Release that was set forth in the Severance Agreement.

8.Cooperation. Executive is permitted to cooperate fully and truthfully with any government authority conducting an investigation into any potential violation of any law or regulation. Nothing in this Agreement is intended to or shall prohibit Executive from providing such cooperation. Executive also agrees to provide reasonable cooperation and assistance to the Company and/or its Board of Directors or any committees thereof in any formal or informal investigation into or litigation involving matters which Executive has relevant knowledge to the extent reasonably requested. Executive agrees and acknowledges that such assistance and cooperation may include, but not be limited to, providing all relevant information and documents reasonably available to Executive about matters on which he worked. Executive agrees to make himself reasonably available to the Company or its representatives at a mutually agreeable time for interviews and meetings regarding any matter relating to his employment or matters on which he worked while employed at the Company as may be reasonably requested. The Company shall reimburse Executive for the reasonable expenses he incurs in the course of cooperating with such Company requests.

9.Release of All Claims. Except as otherwise set forth in this Agreement, Executive hereby releases, acquits and discharges the Company and its affiliates, and their officers, directors, agents, servants, employees, attorneys, shareholders, successors and assigns (collectively, the “Released Parties”), of and from any and all claims, liabilities, demands, causes of action, costs, expenses, attorneys’ fees, damages, indemnities (except those indemnification rights excluded below) and obligations of every kind and nature, in law, equity or otherwise, known or unknown, suspected or unsuspected, disclosed and undisclosed, arising

out of or in any way related to any and all agreements, events, acts or conduct executed or occurring at any time prior to and including the date on which Executive executes this Agreement, including but not limited to: all such claims and demands directly or indirectly arising out of or in any way connected with Executive’s employment with the Company or the termination of that employment; claims or demands related to salary, incentive payments, commissions, stock, stock options, or any other ownership interests in the Company, vacation pay, fringe benefits, expense reimbursements, severance pay, or any other form of compensation (including under the Severance Agreement); claims pursuant to federal, state or local law, statute or cause of action including, but not limited to, the federal Civil Rights Act of 1964, as amended; the Age Discrimination in Employment Act, as amended (the “ADEA”); the federal Americans with Disabilities Act of 1990, as amended; tort law; contract law; wrongful discharge; discrimination; harassment; fraud; defamation; emotional distress; and breach of the implied covenant of implied good faith and fair dealing.

Nothing in this Agreement shall be construed to prohibit Executive from commencing, instituting, participating, providing truthful information, or otherwise assisting in any investigation or proceeding conducted by the Equal Employment Opportunity Commission, the National Labor Relations Board, the Securities and Exchange Commission or any other government agency; provided, however, that by signing this Agreement, Executive agrees to waive and release any right Executive may have to recover monetary relief or compensation from the Released Parties in connection with any such proceeding or investigation. For the avoidance of doubt, nothing herein prevents Executive from receiving any whistleblower or similar award. Further, this release shall not be deemed to affect a release of any claim that may not be released by law, including rights to unemployment or workers compensation, and rights to vested benefits governed by ERISA, nor shall it be deemed to affect a release of any right to enforce the terms of this Agreement or any rights Executive may have to indemnification under the Indemnification Agreement (attached hereto as Exhibit B), the Company’s By-Laws or applicable law.

Executive understands that this Agreement: (i) does not preclude him from challenging the validity of this Agreement, including the waiver and release provisions, under the ADEA; and (ii) does not waive any rights or claims which first arise after the Signature Date.

Executive represents and warrants that Executive has not previously filed or joined in any claim released herein.

10.Waiver and Release Acknowledgement. Executive acknowledges that Executive is knowingly and voluntarily making the above waiver and release. Executive also acknowledges that the consideration given for the waiver and the release in the preceding paragraphs hereof is in addition to anything of value to which Executive was already entitled. Executive further acknowledges that:

11.Acknowledgment Regarding the Age Discrimination in Employment Act and, specifically, 29 U.S.C. 626(f). Executive understands that as part of this Agreement, he voluntarily and knowingly waives rights or claims under the ADEA, and acknowledges that the knowing and voluntary waiver of his claims is in accordance with the ADEA, and, specifically, 29 U.S.C. 6260.

12.Acceptance and Revocation. This Agreement was presented to Executive for review and consideration on November 5, 2019 (“Review Date”). Executive understands that he has had at least twenty-one (21) days from the Review Date within which to decide whether to sign this Agreement and return it to Company. Executive agrees and understands that any changes to this Agreement that may be negotiated between Executive and Company, whether material or immaterial, will not restart the time Executive has to consider and sign the Agreement.

Executive understands that he may sign and return the Agreement at any time before the expiration of the twenty-one (21) day period, Executive further understands that he has seven (7) days after signing this Agreement to revoke it in writing submitted to Carol DiBattiste, General Counsel & Chief Compliance, Privacy and People Officer, at

***@*** (“Revocation Period”). This Agreement shall not become effective until (I) Executive has signed the Agreement, and (2) the Revocation Period has expired without Company having received written notice of a revocation (“Effective Date”).

13.Enforcement. Except as otherwise provided herein, if any action at law or in equity is necessary to enforce or interpret the terms of this Agreement, the prevailing party shall be entitled to reasonable attorneys’ fees, costs and necessary disbursements in addition to any other relief to which such party may be entitled.

14.Costs. The parties intend that each shall bear its own costs, if any, that may have been incurred relating to this Agreement.

15.No Admission of Liability. This Agreement is not an admission of liability by any party.

17.Continuing Obligations. The parties agree that the terms of the Confidentiality Agreement, attached hereto as Exhibit A, and the Indemnification Agreement, attached hereto as Exhibit B, continue in full force and effect. For the avoidance of doubt, nothing herein alters: (i) Executive’s rights or obligations with respect to indemnification as set forth in the Company’s By-Laws or applicable law; or (ii) Executive’s obligations and the Company’s rights under the Confidentiality Agreement as stated above in Paragraph 6.

18.Section 409A. It is intended that all amounts or benefits provided under this Agreement comply with or be exempt from Section 409A of the Internal Revenue Code of 1986, as amended (the “Code”), and treasury regulations relating thereto, so as not to subject Executive to the payment of any interest and tax penalty which may be imposed under Section 409A of the Code, and this Agreement shall be interpreted, construed, and administered accordingly; provided, however, that the Company and the other Released Parties shall not be responsible

for any taxes, penalties, interest or other losses or expenses incurred by Executive due to any failure to comply with Section 409A of the Code. In furtherance thereof, the terms of this Agreement, to the extent necessary, may be modified to be exempt from and so comply with Section 409A of the Code. Each payment under this Agreement as a result of the separation of Executive’s service shall be considered a separate payment for purposes of Section 409A of the Code.

19.Miscellaneous. This Agreement, along with Exhibit A and Exhibit B, constitutes the full and entire understanding and agreement between the parties regarding the subjects hereof. For the avoidance of doubt, Executive acknowledges and agrees that the Company’s entry into this Agreement (and its willingness to make available the consideration set forth in Section 2(a), (c), and (f) above) has resulted in the full and final satisfaction of any and all rights that Executive ever could have pursuant to the Severance Agreement, and Executive shall not be entitled to any payments pursuant to the Severance Agreement, as: (i) neither the Company nor its affiliates shall be deemed to have any further obligations under the Severance Agreement; and (ii) Executive’s sole right to, and eligibility for, severance pay is set forth herein. This Agreement is entered into without reliance on any promise or representation, written or oral, other than those expressly contained herein, and it supersedes any other such promises, warranties or representations. This Agreement may not be modified or amended except in writing signed by both Executive and a duly authorized officer of the Company. This Agreement shall bind the heirs, personal representatives, successors and assigns of both Executive and the Company, and inure to the benefit of both Executive and the Company, their heirs, successors and assigns. Executive represents and warrants that Executive has not previously assigned or transferred, or purported to assign or transfer, to any person or entity, any of the claims released herein and Executive agrees to indemnify and hold harmless the Released Parties from any claim, demand, debt, obligation, liability, cost, expense, right of action or cause of action based on, arising out of or in assignment. If any provision of this Agreement is determined to be invalid or unenforceable, in whole or in part, this determination will not affect any other provision of this Agreement and the provision in question shall be modified by the court so as to be rendered enforceable. This Agreement shall be governed in all respects by the laws of the Commonwealth of Virginia, without reference to its choice of law rules. This Agreement may be signed electronically and in counterparts.

The undersigned state that they have carefully read this Agreement, that they know and understand its terms, and they sign it freely.
