3. Deletion of Exhibit 2. Exhibit 2 (Form of Note) is hereby deleted in its entirety.

4. Effective Date. The Borrower shall, on the date hereof, execute and deliver to Lender the Security Agreement and Security Documents in a form acceptable to Lender. The foregoing delivery shall be a condition to the effectiveness of the amendments set forth in Sections 1—3 above.

The Borrower hereby remakes all representations and warranties contained in the Credit Agreement and reaffirms all covenants set forth therein. The Borrower further certifies that as of the date of this Amendment there exists no Event of Default as defined in the Credit Agreement, nor any condition, act or event which with the giving of notice or the passage of time or both would constitute any such Event of Default. The Borrower agrees that all references to the “Credit Agreement” in the Note (as defined in the Credit Agreement and as amended by this Amendment) shall be a reference to the Credit Agreement as amended hereby and as may be further amended from time to time, and the Note is hereby deemed to be amended accordingly.

7. Counterparts. This Amendment may be executed simultaneously in multiple counterparts, each of which shall be deemed an original, and it shall not be necessary in making proof of this Amendment to produce or account for more than one such counterpart.

8. Continuation of Prior Agreements. It is the intention of the parties hereto that all Loan Documents previously executed by and between the parties shall remain in full force and effect except to the extent they are inconsistent with this Amendment. This Amendment and the Credit Agreement shall be read together, as one document.
