6.1       FOR GOOD AND VALUABLE CONSIDERATION, Borrower hereby forever relieves,
releases, and discharges Collateral Agent and Lenders and their present or former employees, officers, directors, agents, representatives, attorneys, and each of them, from any and all claims, debts, liabilities, demands, obligations, promises,
acts, agreements, costs and expenses, actions and causes of action, of every type, kind, nature, description or character whatsoever, whether known or unknown, suspected or unsuspected, absolute or contingent, arising out of or in any manner
whatsoever connected with or related to facts, circumstances, issues, controversies or claims existing or arising from the beginning of time through and including the date of execution of this Agreement (collectively “Released Claims”).
Without limiting the foregoing, the Released Claims shall include any and all liabilities or claims arising out of or in any manner whatsoever connected with or related to the Loan Documents, the Recitals hereto, any instruments, agreements or
documents executed in connection with any of the foregoing or the origination, negotiation, administration, servicing and/or enforcement of any of the foregoing. 

6.2       By entering into this release, Borrower recognizes that no facts or

settle and release all matters, disputes and differences, known or unknown, suspected or unsuspected; accordingly, if Borrower should subsequently discover that any fact that it relied upon in entering into this release was untrue, or that any
understanding of the facts was incorrect, Borrower shall not be entitled to set aside this release by reason thereof, regardless of any claim of mistake of fact or law or any other circumstances whatsoever. Borrower acknowledges that it is not

cross-complaint or counterclaim against any action, suit, or other proceeding that may be instituted, prosecuted or attempted in breach of this release. Borrower acknowledges that the release contained herein constitutes a material inducement to
Collateral Agent and Lenders to enter into this Agreement, and that Collateral Agent and Lenders would not have done so but for Collateral Agent and Lenders’ expectation that such release is valid and enforceable in all events. 

6.4     Borrower hereby represents and warrants to Collateral Agent and Lenders, and Collateral
Agent and Lenders are relying thereon, as follows: 
 (a)       Except as expressly stated in
this Agreement, neither Collateral Agent, Lenders nor any agent, employee or representative of Collateral Agent or any Lender has made any statement or representation to Borrower regarding any fact relied upon by Borrower in entering into this
Agreement. 
 (b)       Borrower has made such investigation of the facts pertaining to this
Agreement and all of the matters appertaining thereto, as it deems necessary.

Agreement has been carefully read by Borrower, the contents hereof are known and understood by Borrower, and this Agreement is signed freely, and without duress, by Borrower. 

(e)       Borrower represents and warrants that it is the sole and lawful owner of all right,
title and interest in and to every claim and every other matter which it releases herein, and that it has not heretofore assigned or transferred, or purported to assign or transfer, to any person, firm or entity any claims or other matters herein
released. Borrower shall indemnify Collateral Agent and Lenders, defend and hold them harmless from and against all claims based upon or arising in connection with prior assignments or purported assignments or transfers of any claims or matters
