In case any provision contained herein (or part thereof) shall for any reason be held to be invalid, illegal, or unenforceable in any respect, such invalidity, illegality, or other unenforceability shall not affect any other provision (or the remaining part of the affected provision) hereof; but this Note shall be construed as if such invalid, illegal, or unenforceable provision (or part thereof) had never been contained herein, but only to the extent that such provision is invalid, illegal, or unenforceable.
