Hereinafter, all indebtedness owing by Borrowers to Lender under the Equipment Facility shall be referred to as the “Indebtedness.” Capitalized terms used herein and not otherwise defined herein shall have the meaning attributed to such terms in the Loan Agreement.

2. DESCRIPTION OF COLLATERAL. Repayment of the Indebtedness shall be secured by the Collateral described in the Loan Agreement. Hereinafter, the Loan Agreement, together with all other documents securing repayment of the Indebtedness shall be referred to as the “Existing Loan Documents”.

4. CONSISTENT CHANGES. The Existing Loan Documents are hereby amended wherever necessary to reflect the changes described above.

5. NO DEFENSES OF BORROWERS. Borrowers agree that they have no defenses against the obligations to pay any amounts under the Indebtedness.

6. CONTINUING VALIDITY. Each Borrower understands and agrees that in modifying the existing Indebtedness, Lender is relying upon Borrowers’ representations, warranties, and agreements, as set forth in the Existing Loan Documents. Except as expressly modified pursuant to this Agreement, the terms of the Existing Loan Documents remain unchanged and in full force and effect. Lender’s agreement to modifications to the existing Indebtedness pursuant to this Agreement in no way shall obligate Lender to make any future modifications to the Indebtedness. Nothing in this Agreement shall constitute a satisfaction of the Indebtedness. It is the intention of Lender and Borrowers to retain as liable parties all makers and endorsers of Existing Loan Documents, unless the party is expressly released by Lender in writing. No maker, endorser, or guarantor will be released by virtue of this Agreement. The terms of this paragraph apply not only to this Agreement, but also to all subsequent loan modification agreements.
