Debt covenant description										The covenants contained in the credit agreements restrict JOANN’s ability to pay dividends or make other distributions; accordingly, any dividends may only be made in accordance with such covenants. Among other restrictions, the credit agreements permit the public parent company to pay dividends on its common stock in amounts not to exceed the greater of 6% per annum of the net proceeds received by, or contributed to Jo-Ann Stores, LLC from any such public offering of common stock of Jo-Ann Stores, LLC or its direct or indirect parent company, or 7% of Market Capitalization (as defined in the credit agreements). So long as there is no event of default, the credit agreements also allow dividends in amounts not less than $100 million, which amount can increase if certain other conditions are satisfied, including if JOANN’s leverage does not exceed certain thresholds. Additionally, the Revolving Credit Facility allows for unlimited dividends, so long as there is no event of default and the Company’s excess availability after giving pro forma effect for the thirty-day period immediately preceding such payment shall be greater than (a) the greater of 12.5% of the maximum credit and $40 million and the consolidated fixed charge coverage ratio shall be greater than or equal to 1.0 to 1.0 or (b) 17.5% of the maximum credit calculated.
