of completing missing content or correcting erroneous content, without the need for a written amendment, provided that the Bank shall
send a copy of any such modification to the Borrower (which notice may be given by electronic mail). The Borrower agrees to pay on demand,
to the extent permitted by law, all costs and expenses incurred by the Bank in the enforcement of its rights in this Note and in any security

of non-payment, notice of intent to accelerate and notice of acceleration, and any other notice of any kind. The Borrower also waives
all defenses based on suretyship or impairment of collateral. If this Note is executed by more than one Borrower, the obligations of such

that the Borrower may not assign this Note in whole or in part without the Bank&#8217;s written consent and the Bank at any time may assign
this Note in whole or in part.</P>
