2012, the Grantee ceases to be employed by the Employer prior to the Vesting Date on account of death or the Grantee incurs a Long-Term Disability (as defined below), the Grantee’s Time-Based Units shall become fully vested. The Time-Based

Grant Conditions and the Grant Letter: 
 (a) “Cause” shall mean any of the following, as determined in the sole
discretion of the Employer: (1) commission of a felony or a crime involving moral turpitude; (2) fraud, dishonesty, misrepresentation, theft or misappropriation of funds with respect to the Employer; (3) violation of the
Employer’s Code of Conduct or employment policies, as in effect from time to time; (4) breach of any written noncompetition, confidentiality or nonsolicitation covenant of the Grantee with respect to the Employer; or (5) gross
negligence or misconduct in the performance of the Grantee’s duties with the Employer. 
 (b) “Involuntary
Termination” shall mean the Employer’s termination of the Grantee’s employment other than for Cause.

 (d) “Retirement” shall mean the Grantee’s termination of employment other than for Cause after the Grantee has attained age 55 and has completed five years of service with the
Employer. 
 6. Payment. When Time-Based Units vest, shares of Company Stock equal to the vested Time-Based Units shall be issued to the
Grantee within 60 days after the applicable vesting date, subject to applicable tax withholding and subject to any six-month delay required under section 409A of the Internal Revenue Code, if applicable and as described in Section 20(h) of the

Time-Based Units shall be subject to applicable laws, rules and regulations and also to such approvals by governmental agencies as may be deemed appropriate to comply with relevant securities laws and regulations. 

9. No Shareholder Rights. No shares of Company Stock shall be issued to the Grantee on the Date of Grant, and the Grantee shall not be, nor have
any of the rights or privileges of, a shareholder of the Company with respect to any Time-Based Units.

no representations or undertakings regarding the treatment of any Taxes in connection with any aspect of the Time-Based Units, including the grant, vesting or settlement of the Time-Based Units; and (ii) does not commit to structure the terms
of the grant or any aspect of the Time-Based Units to reduce or eliminate the Grantee’s liability for Taxes. Further, if the Grantee has become subject to tax in more than one jurisdiction between the date of grant and the date of any relevant

determined in accordance with, the applicable laws of the Commonwealth of Pennsylvania, excluding any conflicts or choice of law rule or principle. 
 15. No Entitlement or Claims for Compensation. In connection with the acceptance of the grant of the Time-Based Units under the Grant Letter and these Grant Conditions, the Grantee acknowledges the
following: 
 (a) the Plan is established voluntarily by the Company, the grant of the Time-Based Units under the Plan is made at
the discretion of the Committee and the Plan may be modified, amended, suspended or terminated by the Company at any time; 

(b) the grant of the Time-Based Units under the Plan is voluntary and occasional and does not create any contractual or other right to
receive future grants of Time-Based Units, or benefits in lieu of them, even if Time-Based Units have been granted repeatedly in the past; 
 (c) all decisions with respect to future grants of Time-Based Units, if any, will be at the sole discretion of the Committee; 
 (d) the Grantee is voluntarily participating in the Plan; 
 (e) the Time-Based
Units are extraordinary items that do not constitute compensation of any kind for services of any kind rendered to the Employer (including, as applicable, the Grantee’s employer) and which are outside the scope of the Grantee’s employment
contract, if any; 
 (f) the Time-Based Units are not to be considered part of the Grantee’s normal or expected
compensation or salary for any purpose, including, but not limited to, calculating any severance, resignation, termination, payment in lieu of notice, redundancy, end of service payments, bonuses, long-service awards, pension or retirement or
welfare benefits or similar payments; 
 (g) the Time-Based Units are not intended to replace any pension rights or
compensation; 

  
 4 

 (h) the grant of Time-Based Units and the Grantee’s participation in the Plan will not
be interpreted to form an employment contract or relationship with the Employer; 
 (i) the future value of the underlying
shares of Company Stock is unknown and cannot be predicted with certainty. The Grantee understands that the Company is not responsible for any foreign exchange fluctuation between the United States Dollar and the Grantee’s local currency that
may affect the value of the Time-Based Units; and 
 the Grantee shall have no rights, claim or entitlement to compensation or damages as a
result of the Grantee’s cessation of employment for any reason whatsoever, whether or not in breach of contract or local labor law, insofar as these rights, claim or entitlement arise or may arise from the Grantee’s ceasing to have rights
under or be entitled to receive payment under or ceasing to have the opportunity to participate in the Plan as a result of such cessation or loss or diminution in value of the Time-Based Units as a result of such cessation, and the Grantee
irrevocably releases the Employer from any such rights, entitlement or claim that may arise. If, notwithstanding the foregoing, any such right or claim is found by a court of competent jurisdiction to have arisen, then the Grantee shall be deemed to
have irrevocably waived the Grantee’s entitlement to pursue such rights or claim.
