              From and after the Amendment Effective Date, all references to the Agreement shall, unless otherwise specifically provided,

              3.5

            	
              If any one or more of the covenants, agreements, provisions or terms of this Amendment shall for any reason whatsoever be
                held invalid, then such covenants, agreements, provisions or terms shall be deemed severable from the remaining covenants, agreements, provisions or terms of this Amendment and shall in no way affect the validity or enforceability of the
                other provisions of this Amendment or rights of any party hereto; provided, that in case any provision in or obligation under this Amendment should
                be invalid, illegal or unenforceable in any jurisdiction, the validity, legality and enforceability of the remaining provisions or obligations, or of such provision or obligation in any other jurisdiction, shall not in any way be affected
                or impaired thereby.  The parties hereto shall endeavor in good-faith negotiations to replace the invalid, illegal or unenforceable provisions with valid provisions the economic effect of which comes as close as possible to that of the
                invalid, illegal or unenforceable provisions.
