Capitalized terms used herein and not otherwise defined herein are used herein as defined in the Credit Agreement.

This note is a Note issued pursuant to the terms of Section 2.03 of the Credit Agreement, and this note and the holder hereof are entitled to all the benefits and security provided for thereby or referred to therein, to which Credit Agreement reference is hereby made for a statement thereof.

The Borrower hereby waives, to the extent permitted by applicable law, demand, presentment, protest or notice of any kind hereunder, other than notices provided for in the Loan Documents. The non-exercise by the holder hereof of any of its rights hereunder in any particular instance shall not constitute a waiver thereof in such particular or any subsequent instance.

THIS NOTE MAY NOT BE TRANSFERRED EXCEPT IN COMPLIANCE WITH THE TERMS OF THE CREDIT AGREEMENT.
