The Company also agreed that during the Forbearance Period the default provision in the BWV Promissory Notes relating to insolvency of BWV will not apply.

BWV agreed in the Forbearance Agreement to make the following required payments during the Forbearance Period towards the remaining principal balance of the April 2024 Promissory Note: (1) monthly payments equal to 15% of cash receipts of BWV or its subsidiaries from certain sale or licensing revenues or payments; and (2) payment of 10% of the net proceeds from certain financing or other transactions outside the ordinary course of business completed by BWV or any of its subsidiaries during the Forbearance Period. The remaining balance of the April 2024 Promissory Note will be due at the end of the Forbearance Period.

The Forbearance Agreement does not affect the maturity date of the September 2024 Promissory Note, which continues to have a maturity date of September 30, 2024 for the payment of the full principal amount of $5.0 million.
