Escrow deposit description |  |  |  |  |  |  |  |  |  | on or before October 17, 2022, the Company (i) must deposit $1,000,000 into escrow as the Third Deposit, (ii) will not be required to make the second deposit of $1,950,000 pursuant to the Addendum and the Addendum Agreement, or redeem the first tranche of October Secured Notes. Additionally, the First Reconcile Date was extended to October 12, 2022. The Company gave notice to the Noteholders on October 10, 2022 that the Company would be conducting an equity financing. This in turn paused the commencement of (a) the Second Conversion and the Second Reconcile Date, and (b) the Third Conversion and the Third Reconcile Date, in each case, for forty-five (45) Trading Days, each as defined in the Addendum. This also had the effect of pausing the Company’s requirement to make the Third Deposit of $1,000,000 under the October Purchase Agreement as amended by the Addendum, for 45 Trading Days. The 45-day trading window opened on December 20, 2022 to allow the Noteholders to apply the 20% discount to the 5-day VWAP of the Company’s stock. |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
