[1] PSUs granted shall be adjusted as if the shares of common stock represented by such PSUs had received any applicable stock or cash dividends declared. As for stock dividends, a number of PSUs shall be added to the target amount corresponding to the number of shares of common stock that would have been payable per such stock dividend on the then outstanding number of PSUs under the agreement as if common stock had been issued for such PSUs. As to cash dividends, a number of PSUs shall be added to the target amount corresponding to the number of shares of common stock that could have been acquired by the cash dividend payable on the then outstanding number of PSUs under the agreement as if common stock had been issued for such PSUs, and the calculation of the number of shares of common stock that could have been acquired shall be based on the closing price of the common stock on the record date for the cash dividend at issue.

[2] Includes 1,247,098 shares classified as a liability due to the potential cash component.

[3] Includes 566,862 shares classified as a liability due to the potential cash component.

[4] As of the Effective Date and pursuant to the Plan, all outstanding PSUs of the Predecessor Company were deemed cancelled.

[5] In connection with the restructuring and support agreement, dated as of August 18, 2020, by and between the Predecessor Company and certain beneficial owners and/or investment advisors or managers of discretionary funds, accounts or other entities for the holders of beneficial owners (the "Consenting Noteholders"), the 2020 PSUs were cancelled.

[6] The value of the PSU awards is estimated on the date of grant using a Monte Carlo simulation model. The valuation consists of computing the fair value using CBL's simulated stock price as well as TMR for each performance period. The award is modeled as a contingent claim in that the expected return on the underlying shares is risk-free and the rate of discounting the payoff of the award is also risk-free.

[7] The value of the PSU awards is estimated on the date of grant using a Monte Carlo simulation model. The valuation consists of computing the fair value using CBL's simulated stock price as well as TSR over a three-year performance period. The award is modeled as a contingent claim in that the expected return on the underlying shares is risk-free and the rate of discounting the payoff of the award is also risk-free. The weighted-average fair value per share related to the 2020 PSUs classified as equity consists of 2,131,245 shares at a fair value of $0.88 (which relate to relative TSR) and 1,065,463 shares at fair value of $0.75 per share (which relate to absolute TSR).

[8] The risk-free interest rate was based on the yield curve on zero-coupon U.S. Treasury securities in effect as of the valuation date, which is the grant date listed above.

[9] The risk-free interest rate was based on the yield curve on zero-coupon U.S. Treasury securities in effect as of the valuation date, which is the respective grant date listed above.

[10] The computation of expected volatility was based on the historical volatility of the share prices of comparable, publicly traded companies and given the Company's risk profile and leverage relative to the comparable, publicly traded companies. The Company's historical volatility was not relied upon given the Company's limited trading history since the Effective Date.

[11] The computation of expected volatility was based on a blend of the historical volatility of CBL's shares of common stock based on annualized daily total continuous returns over a five-year period for the 2020 PSUs and implied volatility data based on the trailing month average of daily implied volatilities implied by stock call option contracts that were both closest to the terms shown and closest to the money.
