Lenders rights and remedies under this Agreement, the Loan Documents, and all other agreements are cumulative. Lenders have all rights and remedies provided under the Code, by law, or in equity. Lenders exercise of one right or remedy is not an election, and Lenders waiver of any Event of Default is not a continuing waiver. Lenders delay is not a waiver, election, or acquiescence. No waiver hereunder shall be effective unless signed by each Lender and then is only effective for the specific instance and purpose for which it was given.
