As to each and every claim released hereunder, each Loan Party also waives the benefit of each other similar provision of applicable federal or state law (including without limitation the laws of the state of New York), if any, pertaining to general releases after having been advised by its legal counsel with respect thereto.

Each Loan Party acknowledges that it may hereafter discover facts different from or in addition to those now known or believed to be true with respect to such claims, demands, or causes of action and agrees that this instrument shall be and remain effective in all respects notwithstanding any such differences or additional facts.

Accordingly, for and in consideration of the agreements contained in this Amendment and other good and valuable consideration, each Lender (for itself and its Affiliates and the successors, assigns, heirs and representatives of each of the foregoing) (collectively, the “ Lender Releasors ”) does hereby fully, finally, unconditionally and irrevocably release and forever discharge Cortland Capital Market Services LLC, Colbeck Capital Management, LLC, CB Agent Services LLC and each of their respective Affiliates, officers, directors, employees, attorneys, consultants and agents (collectively, the “ Colbeck/Cortland Released Parties ”) from any and all debts, claims, obligations, damages, costs, attorneys’ fees, suits, demands, liabilities, actions, proceedings and causes of action, in each case, arising on or prior to the Consent Effective Date, whether known or unknown, contingent or fixed, direct or indirect, and of whatever nature or description, and whether in law or in equity, under contract, tort, statute or otherwise, which any Lender Releasor has heretofore had or now or hereafter can, shall or may have against any Colbeck/Cortland Released Party by reason of any act, omission or thing whatsoever done or omitted to be done on or prior to the Consent Effective Date and arising out of, connected with or related in any way to this Amendment, the Financing Agreement or any other Loan Document, or any act, event or transaction on or prior to the Consent Effective Date related or attendant thereto, or the agreements of Cortland Capital Market Services LLC, Colbeck Capital Management, LLC, CB Agent Services LLC or any of their respective Affiliates contained therein, or the possession, use, operation or control of any of the assets of each Loan Party, or the making of any Loans or other advances, or the management of such Loans or advances or the Collateral on or prior to the Consent Effective Date.

“A GENERAL RELEASE DOES NOT EXTEND TO CLAIMS WHICH A CREDITOR DOES NOT KNOW OR SUSPECT TO EXIST IN HIS FAVOR AT THE TIME OF EXECUTING THE RELEASE, WHICH IF KNOWN BY HIM, MUST HAVE MATERIALLY AFFECTED HIS SETTLEMENT WITH THE DEBTOR.”

As to each and every claim released hereunder, each Lender also waives the benefit of each other similar provision of applicable federal or state law (including without limitation the laws of the state of New York), if any, pertaining to general releases after having been advised by its legal counsel with respect thereto.
