2. <u>Representation and Warranties of the Company</u>. The Company hereby represents and warrants to Holder that:

(a) <u>Organization</u>. The Company is a corporation duly organized, validly existing and in good standing under the laws of the State of Delaware and has all requisite corporate power and authority to carry on its business as currently conducted.

(b) <u>Corporate Power</u>. The Company has all requisite legal and corporate power to enter into, execute and deliver this Amendment, and the Notes as amended hereby represent a valid and binding obligation of the Company, enforceable in accordance with its terms, except as the same may be limited by bankruptcy, insolvency, reorganization, fraudulent conveyance, moratorium, usury or other laws of general application relating to or affecting enforcement of creditors' rights and the rules or laws governing specific performance, injunctive relief or other equitable remedies.

------

(c) <u>Authorization</u>. All corporate and legal action on the part of the Company, its shareholders, directors and officers necessary for entry into this Amendment and the Company's performance of its obligations under the Notes as amended hereby have been taken.

3. <u>Representations and Warranties of the Holder</u>. Holder hereby represents and warrants to the Company that:

(a) <u>Authorization</u>. The Holder has full power and authority to enter into this Amendment.

In this connection, the Holder is familiar with Rule 144, as presently in effect, and understands the resale limitations imposed thereby and by the Securities Act.
