Purchase Agreement, description	The Purchase Agreement, AVCT is required to complete an equity offering (the “Equity Offering”) prior to, or simultaneously with, the closing of the Transaction (the “Closing”), and in the event AVCT is successful in raising at least $100.0 million in the Equity Offering, AVCT will sell additional securities in the Equity Offering resulting in proceeds in an amount up to the value of 20% of the Issued Shares being issued to Ribbon, with the value of each Issued Share being equal to (i) the value of the AVCT common stock or other securities convertible into a share of AVCT common stock that is being sold in the Equity Offering, or (ii) in the event another form of securities is being offered in the Equity Offering, or if the Equity Offering is consummated more than five days prior to the Closing, the volume weighted average price of AVCT common stock for the ten trading days immediately prior to the Closing (the equivalent shares sold, “Sold Shares”). AVCT will deliver to Ribbon, as part of the Purchase Price, the gross proceeds from the sale of additional securities in the Equity Offering in excess of $100.0 million, in lieu of the Sold Shares at the Closing. In the event that AVCT’s Pro Forma Total Enterprise Value (as defined in the Purchase Agreement), after taking into account the Equity Offering proceeds, would be below $275.0 million, AVCT and Ribbon have agreed to negotiate a potential change in the number of Issued Shares.
