Description of sixth amendment           ●On November 20, 2023, the Company entered into a Sixth Amendment that waived defaults caused by our failure to achieve the required Fixed Charge Coverage Ratio of the Fifth Amendment and because we purchased capital expenditures (as defined) in excess of permitted amounts.
