In consideration for the agreements by Bank herein, Borrower and Guarantor fully, finally, and forever release and discharge Bank, and Bank’s predecessors, successors, assigns, subsidiaries, affiliates, parent, directors, officers, employees, agents, and representatives from any and all actions, causes of action, claims, debts, demands, liabilities, obligations, and suits, of whatever kind or nature, in law or equity, that Borrower or Guarantor have or in the future may have, whether known or unknown in respect of the Loan, the Loan Documents, or the actions or omissions of Bank in respect of the Loan or the Loan Documents that arise from events occurring prior to the date of this Letter Agreement. It is the intention of Borrower and Guarantor that the above release shall be effective as a full and final release of each and every matter specifically and generally referred to above. Borrower and Guarantor acknowledge and represent that they have been advised by independent legal counsel with respect to the agreements contained herein.

All other requirements, terms and conditions outlined in the Loan Documents shall remain unchanged.
