The unpaid principal amount of this Note shall be paid at the times and in the manner set forth in Section 9 of the Letter Agreement, but if not sooner paid or demanded, the entire unpaid principal amount of this Note, together with accrued and unpaid interest thereon, shall be due and payable on the Maturity Date, unless such date shall be extended pursuant to Section 3 of the Letter Agreement.

Interest on the unpaid principal amount of this Note shall be payable at the rates set forth in Section 6 of the Letter Agreement and at the times and in the manner specified in Section 9 of the Letter Agreement.

Capitalized terms used herein without definition shall have the meanings set forth in the Letter Agreement.

Overdue payments of principal (whether at stated maturity, by acceleration or otherwise), and, to the extent permitted by law, overdue interest, shall bear interest at the rate and in the manner set forth in the Letter Agreement. Any late payment of principal or interest shall be subject to a late payment charge set forth in the Letter Agreement. The foregoing shall not affect the Bank’s rights to exercise any of its rights and remedies provided in the Letter Agreement if an Event of Default has occurred.

No reference to the Letter Agreement or any provision thereof shall affect or impair the absolute and unconditional obligation of the Maker of this Note to pay the principal of and interest on this Note as herein provided.
