sale will not constitute Disqualified Capital Stock if (x) the terms of such Equity Interest provide that the Borrower may not repurchase or redeem any such Equity Interest pursuant to such provisions unless such repurchase or redemption
complies with Section 9.04 or (y) the terms of such Equity Interest provide that the Borrower may not repurchase or redeem any such Equity Interest pursuant to such provisions prior to the date on which there are no Loans, LC Exposure or
other monetary obligations outstanding under this Agreement and all of the Commitments are terminated. The amount (or principal amount) of Disqualified Capital Stock deemed to be outstanding at any time for purposes of this Agreement will be the
maximum amount that the Borrower and its Restricted Subsidiaries may become obligated to pay upon the maturity of, or pursuant to any mandatory redemption provisions of, such Disqualified Capital Stock, exclusive of accrued dividends. For the
avoidance of doubt, the Preferred Shares shall not be deemed to be Disqualified Capital Stock for purposes of this Agreement.
