Business combination, description								The 2021 Bridge Amendment was executed to provide the Company additional time to finalize the Business Combination. The 2021 Bridge Amendment amended the terms of the 2021 Bridge Debentures to, among other things: (i) permit the Company to undertake another offering of convertible debentures, (ii) allow the Company to extend the maturity dates of the 2021 Bridge Debentures an additional five months following the end of the initial three-month extension period, discussed above, and (iii) implement additional amounts owed on the outstanding balance of the 2021 Bridge Debentures under certain circumstances, the first of which related to the signing of the Merger Agreement and resulted in an increase in the outstanding balance of approximately 135%, which was followed by an additional increase of approximately 145% of the outstanding balance when the 2021 Bridge Debentures remained outstanding at the end of the initial three-month extension period.
