8.General Provisions.

(a)Entire Agreement.    This Agreement supersedes all prior agreements, written or oral, between the Employee and
the Company relating to the subject matter of this Agreement. This Agreement may not be modified, changed or discharged in whole or in part, except by an agreement in writing signed by the Employee
and the Company. The Employee agrees that any change or changes in his duties, salary or compensation after the signing of this Agreement shall not affect the validity or scope of this Agreement.

(b)Interpretation.    If the Employee violates the provisions of Section 5 of this Agreement, the Employee
shall continue to be bound by the restrictions set forth in Section 5 until a period of one (1) year has expired without any violation of such provisions. If any restriction set forth in
Section 5 is found by any court of competent jurisdiction to be unenforceable because it extends for too long a period of time or over too great a range of activities or in too broad a
geographic area, it shall be

3

interpreted
to extend only over the maximum period of time, range of activities or geographic area as to which it may be enforceable.

(c)Severability.    The invalidity or unenforceability of any provision of this Agreement shall not affect or
impair the validity or enforceability of any other provision of this Agreement.

(d)Waiver.    No delay or omission by the Company in exercising any right under this Agreement will operate as a
waiver of that or any other right. A waiver or consent given by the Company on any one occasion is effective only in that instance and will not be construed as a bar to or waiver of any right on any
other occasion.

(e)Employee Acknowledgment and Equitable Remedies.    The Employee acknowledges that the restrictions contained in
this Agreement are necessary for the protection of the business and goodwill of the Company and considers the restrictions to be reasonable for such purpose. The Employee agrees that any breach of
this Agreement is likely to cause the Company substantial and irrevocable damage and that therefore, in the event of any breach of this Agreement, the Employee agrees that the Company, in addition to
any and all such other remedies that may be available, shall be entitled to specific performance and other injunctive relief without posting a bond.

(f)Successors and Assigns.    This Agreement shall be binding upon and inure to the benefit of both parties and
their respective successors and assigns, including any corporation or entity with which or into which the Company may be merged or which may succeed to its assets or business, provided however that
the obligations of the Employee are personal and shall not be assigned by the Employee.

(g)Subsidiaries and Affiliates.    The Employee expressly consents to be bound by the provisions of this Agreement
for the benefit of the Company or any subsidiary or affiliate thereof to whose employ the Employee may be transferred without the necessity that this Agreement be re-signed at the time of
such transfer.

(h)Governing Law, Forum and Jurisdiction.    This Agreement shall be governed by and construed as a sealed
instrument under and in accordance with the laws of the Commonwealth of Pennsylvania (without reference to the conflicts of law provisions thereof). Any action, suit, or other legal proceeding that is
commenced to resolve any matter arising under or relating to any provision of this Agreement shall be commenced only in a court of the Commonwealth of Pennsylvania (or, if appropriate, a federal court
located within Pennsylvania), and the Company and the Employee each consents to the jurisdiction of such a court.

(i)Captions.    The captions of the sections of this Agreement are for convenience of reference only and in no way
define, limit or affect the scope or substance of any section of this Agreement.
