Further, characterization of any Account Receivable due from an account debtor as an Eligible Receivable shall not be deemed a determination by the Lender as to its actual value and shall not in any way obligate the Lender to accept any Account Receivable subsequently arising from such account debtor to be, or to continue to deem such Account Receivable to be, an Eligible Receivable. The Borrower acknowledges that it is the Borrower’s responsibility to determine the creditworthiness of account debtors and all risks concerning the same and that collection of Accounts Receivable are with the Borrower.

The Borrower’s promise and obligation to repay each Revolving Advance shall be evidenced by this Agreement and the Note, and the principal amount of each Revolving Advance shall be added to the principal balance due under the Note.
