Agreement and the Loan Documents other than those changes expressly set forth in this Amendment. This Amendment shall not

or both would constitute an Event of Default by Borrower under any of the Loan Documents or any of the Administrative Agent’s
or the Lenders’ rights and remedies with respect thereto. The validity, priority and perfection of all security interests
and other liens granted or created by the Loan Documents is hereby acknowledged and confirmed, and the Loan Documents shall continue

or other liens.

“Released Parties”) of and from any and all claims, liabilities, demands, obligations, damages, losses, actions
and causes of action whatsoever which the Borrower or any of the other Loan Parties may now have or claim to have against the
Released Parties as of the date hereof, whether presently known or unknown and of any nature and extent whatsoever, including,
without limitation, on account of or in any way affecting, concerning or arising out of or founded upon this Amendment, the Credit
Agreement, or any of the Loan Documents, including but not limited to all such loss or damage of any kind heretofore sustained
or that may arise as a consequence of the dealings between the parties up to and including the date hereof, including but not
limited to, the administration or enforcement of the Obligations, the Loan or any of the Loan Documents. The obligations of the
Borrower and the other Loan Parties under the Loan Documents and the Credit Agreement, as amended by this Amendment, shall be
absolute and unconditional and shall remain in full force and effect without regard to, and shall not be released, discharged
or in any way affected by:


 


(i)       any
exercise or non-exercise of any right, remedy, power or privilege under or in respect of the Credit Agreement, as amended by this
Amendment, the Loan Documents or any document relating to or evidencing any of the Lender’s liens or applicable law, including,
without limitation, any waiver, consent, extension, indulgence or other action or inaction in respect thereof; or


 


(ii)       any
other act or thing or omission or delay to do any other act or thing which could operate to or as a discharge of the Borrower
or any other Loan Party as a matter of law, other than payment in full of all Obligations, including but not limited to all obligations
under the Loan Documents and the Credit Agreement, as amended by this Amendment.


 






    	 	 	 



    	 	 	 



    

 


(c)       Counterparts.
This Amendment may be signed in counterparts (by facsimile transmission or otherwise), but all of which together shall constitute
one and the same instrument.


 


(d)       Incorporation
into Credit Agreement. This Amendment shall be incorporated into the Credit Agreement by this reference. All representations,
warranties, Events of Default, and covenants set forth herein shall be a part of the Credit Agreement as if originally contained
therein.


 


(e)       Governing
Law. This Amendment shall be deemed to be a contract under the Laws of the Commonwealth of Pennsylvania and for all purposes

regard to its conflict of laws principles.


 


(f)       No
Novation. Except as amended hereby, all of the terms and conditions of the Credit Agreement and the other Loan Documents shall
remain in full force and effect. Borrower, the other Loan Parties, each Lender, and Administrative Agent acknowledge and agree
that this Amendment is not intended to constitute, nor does it constitute, a novation, interruption, suspension of continuity,
satisfaction, discharge or termination of the obligations, loans, liabilities, or indebtedness under the Credit Agreement or the
