We have not reviewed any documents other than the Subject Documents. In particular, except for the Subject Documents, we have not reviewed any documents that may be referred to in or incorporated by reference into any of the Subject Documents. With your permission, we have conducted no independent factual investigation but have relied solely upon the Subject Documents. In the course of our examination of the Subject Documents, we have assumed: (i) the genuineness of all signatures; (ii) the authenticity of all documents submitted to us as originals; (iii) the conformity to original documents of all documents submitted to us as conformed or other copies and the authenticity of the originals of such documents and (iv) the legal capacity of all natural persons.

This opinion relates solely to those laws, rules and regulations of the Commonwealth of Pennsylvania (excluding securities and blue sky laws) which, in our experience, are normally applicable to the transactions contemplated by the Indenture (the “Applicable Laws”), and no opinion is expressed with respect to the laws, rules or regulations of the United States of America, any jurisdiction other than the Commonwealth of Pennsylvania or, other than the Applicable Laws, the Commonwealth of Pennsylvania.

Based on the foregoing, and subject to the qualifications stated herein, we are of the opinion that:

1. The Company is a corporation duly incorporated and validly subsisting under the laws of the Commonwealth of Pennsylvania.

2. The Company has all requisite corporate power and authority to execute and deliver the Indenture and to perform its obligations thereunder, including its obligations under Article XI thereof (the “Guaranty”).

3. The execution and delivery by the Company of the Indenture and the performance by the Company of its obligations thereunder, including the Guaranty, have been duly authorized by all necessary corporate actions on the part of the Company.

4. No consent, approval, waiver, license or authorization or other action by or filing with any Pennsylvania governmental authority is required to be obtained or made by the Company under the Applicable Laws solely as a result of the execution and delivery by the Company of the Indenture or the performance by the Company of its obligations thereunder, including the Guaranty.

5. The execution and delivery by the Company of the Indenture and the performance by the Company of its obligations thereunder, including the Guaranty, do not and will not violate any Applicable Laws or any of the terms of the Charter Documents.
