leaving Employee with an amount, net after all federal, state and local taxes, equal to the amount Employee would have had if no portion of his benefit under the Plan constituted an “excess parachute payment.” Notwithstanding the

six months after the date of Employee’s separation from service with the Company, so as to comply with the special rule for certain “specified employees” set forth in Code Section 409A(a)(2)(B)(i) unless it is determined that
immediate distribution is permissible (and does not trigger any additional tax liability pursuant to Code Section 409A(a)(l)) pursuant to Code Section 409A(a)(2)(A)(v) by reason of being payable in connection with a change in the ownership
or effective control of the Company or in the ownership of a substantial portion of the assets of the Company or is otherwise determined not to be subject to such additional tax liability.

 17. Waiver. The waiver of the breach of any term or provision of this Agreement shall not operate
as or be construed to be a waiver of any other or subsequent breach of this Agreement. 
 18. Governing Law. This Agreement shall be
construed and enforced in accordance with the laws of the Commonwealth of Pennsylvania without reference to conflict of laws principles. 
 19. Invalidity. In case any one or more of the provisions contained in this Agreement shall, for any reason, be held to be invalid, illegal or unenforceable in any respect, such invalidity, illegality or unenforceability shall not
affect the validity of any other provision of this Agreement, and such provision(s) shall be deemed modified to the extent necessary to make it enforceable. 
 20. Section Headings. The section headings in this Agreement are for convenience only; they form no part of this Agreement and shall not affect its interpretation. 
 21. Number of Days. In computing the number of days for purposes of this Agreement, all days shall be counted, including Saturdays, Sundays and
legal holidays; provided, however, that if the final day of any time period falls on a Saturday, Sunday or day which is a holiday in the Commonwealth of Pennsylvania, then such final day shall be deemed to be the next day which is not a Saturday,
Sunday or legal holiday. 
 22. Specific Enforcement Extension of Period. 
 (a) Employee acknowledges that the restrictions contained in Sections 6, 7 and 8 hereof survive the termination of his employment, regardless of the
reason, and are reasonable and necessary to protect the legitimate interests of the Company and/or its Related Entities and that the Company and/or its Related Entities would not have entered into this Agreement in the absence of such restrictions.
Employee also acknowledges that any breach by him of Sections 6, 7 or 8 hereof will cause continuing and irreparable injury to the Company and/or its Related Entities for which monetary damages would not be an adequate remedy. The Employee shall
not, in any action or proceeding to enforce any of the provisions of this Agreement, assert the claim or defense that an adequate remedy at law exists. In the event of such breach by Employee, the Company and/or its Related Entities shall have the
right to enforce the provisions of Sections 6, 7 and 8 of this Agreement by seeking injunctive or other relief in any court, and this Agreement shall not in any way limit remedies of law or in equity otherwise available to the Company. If an action
at law or in equity is necessary to enforce or interpret the terms of this Agreement, the prevailing party shall be entitled to recover, in addition to any other relief, reasonable attorneys’ fees, costs and disbursements. In the event that the
provisions of Sections 6, 7 or 8 hereof should ever be adjudicated to exceed the time, geographic, or other limitations permitted by applicable law in any applicable jurisdiction, then such provisions shall be deemed reformed in such jurisdiction to
the maximum time, geographic, or other limitations permitted by applicable law. 
 (b) In the event that Employee shall be in breach of any
of the restrictions contained in Section 8 hereof, then the Restricted Period shall be extended for a period of time equal to the period of time that Employee is in breach of such restriction.

 (c) In the event that Employee shall be in breach of any of the restrictions contained in Sections 6, 7
or 8 hereof, Employee shall forfeit his right to any further payments pursuant to Section 9 (without limiting any other relief to which the Company and/or its Related Entities may be entitled), but the release in the termination letter as
described in Section 10 will remain in full force and effect. 
 23. Consent to Suit. Any legal proceeding arising out of or
relating to this Agreement shall be instituted in the U.S. District Court of the Eastern District of Pennsylvania, or if such court does not have jurisdiction or will not accept jurisdiction, in any court of general jurisdiction in the Commonwealth
of Pennsylvania, and the Employee hereby consents to the personal and exclusive jurisdiction of such court and hereby waives any objection that the Employee may have to the laying of venue of any such proceeding and any claim or defense of
inconvenient forum. 
 24. Counterparts. This Agreement may be executed in one or more counterparts, each of which shall be deemed an
original, and all of which together shall be deemed to be one and the same instrument.
