              Section 13.1 of the Loan Agreement is hereby amended by amending and restating the following defined term in its entirety:

            


      

      

      “Cash Equivalents” are (a) marketable direct obligations issued or unconditionally guaranteed by the United States or any agency or any State thereof having
        maturities of not more than two (2) years from the date of acquisition, (b) marketable obligations fully collateralized by Cash Equivalents of the kinds described in clause (a), (c) commercial paper maturing no more than two (2) years after its
        creation and having the highest rating from either Standard & Poor’s Ratings Group or Moody’s Investors Service, Inc., (e) certificates of deposit maturing no more than two (2) years after issue provided that the account in which any such

        transaction, or otherwise holding or engaging in any ownership interest in any type of Auction Rate Security by Borrower or any of its Subsidiaries shall be conclusively determined by the Lenders as an ineligible Cash Equivalent, and any such

        purchasing participations in, entering into any type of swap or other equivalent derivative transaction, or otherwise holding or engaging in any ownership interest in any type of debt instrument, including, without limitation, any corporate or
        municipal bonds with a long-term nominal maturity for which the interest rate is reset through a dutch auction and more commonly referred to as an auction rate security (each, an “Auction Rate Security”).

            	a.	
              FOR GOOD AND VALUABLE CONSIDERATION, Borrower hereby forever relieves, releases, and discharges Collateral Agent and each Lender and their respective 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 Amendment solely to the extent such claims arise out of or are 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 (collectively “Released Claims”).

            


       

      	

            	b.	
              In furtherance of this release, Borrower expressly acknowledges and waives any and all rights under Section 1542 of the California Civil Code, which provides as follows:

            


       

      “A general release does not extend to claims that the creditor or releasing party does not know or suspect to exist in his or her
        favor at the time of executing the release and that, if known by him or her, would have materially affected his or her settlement with the debtor or releasing party.” (Emphasis added.)

      

      

      	

            	c.	
              By entering into this release, Borrower recognizes that no facts or representations are ever absolutely certain and it may hereafter discover facts in addition to or different from those which it presently knows or believes to be true,
                but that it is the intention of Borrower hereby to fully, finally and forever settle and release all matters, disputes and differences, known or unknown, suspected or unsuspected in respect of the Released Claims; 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 relying upon and has not relied upon any representation or statement made by Bank with respect to the facts
                underlying this release or with regard to any of such party’s rights or asserted rights.

            


       

      	

            	d.	
              This release may be pleaded as a full and complete defense and/or as a 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 the Lenders to enter into this Amendment, and that Collateral Agent and the Lenders would not have done so but for Collateral Agent’s
                and the Lenders’ expectation that such release is valid and enforceable in all events.

            


      

      

      	

            	e.	
              Borrower hereby represents and warrants to Collateral Agent and the Lenders, and Collateral Agent and the Lenders are relying thereon, as follows:

            


       

      	

            	i.	
              Except as expressly stated in this Amendment, neither Collateral Agent, the Lenders nor any agent, employee or representative of any of them has made any statement or representation to Borrower regarding any
                fact relied upon by Borrower in entering into this Amendment.

                arising in connection with prior assignments or purported assignments or transfers of any claims or matters released herein.

            


       

      	

            	8.	
              To induce Collateral Agent and the Lenders to enter into this Amendment, Borrower hereby represents and warrants to Collateral Agent and the Lenders as follows:

            


       

      	

            	a.	
              Immediately after giving effect to this Amendment (i) the representations and warranties contained in the Loan Documents are true, accurate and complete in all material respects as of the date hereof (except to the extent such

            	b.	
              Borrower has the power and due authority to execute and deliver this Amendment and to perform its obligations under the Loan Agreement, as amended by this Amendment;

            	d.	
              The execution and delivery by Borrower of this Amendment and the performance by Borrower of its obligations under the Loan Agreement, as amended by this Amendment, do not and will not contravene (i) any law or regulation binding on or
                affecting Borrower, (ii) any contractual restriction with a Person binding on Borrower, (iii) any order, judgment or decree of any court or other governmental or public body or authority, or subdivision thereof, binding on Borrower, or (iv)
                the organizational documents of Borrower;

            


       

      	

            	e.	
              The execution and delivery by Borrower of this Amendment and the performance by Borrower of its obligations under the Loan Agreement, as amended by this Amendment, do not require any order, consent, approval, license, authorization or
                validation of, or filing, recording or registration with, or exemption by any governmental or public body or authority, or subdivision thereof, binding on Borrower, except as already has been obtained or made; and

            


       

      	

            	f.	
              This Amendment has been duly executed and delivered by Borrower and is the binding obligation of Borrower, enforceable against Borrower in accordance with its terms, except as such enforceability may be limited by bankruptcy, insolvency,
                reorganization, liquidation, moratorium or other similar laws of general application and equitable principles relating to or affecting creditors’ rights.
