Each of the Fourth Supplemental Indenture and First Supplemental Indenture provided for, among other things, (i) modifications to the conversion privileges of the holders of the Notes issued thereunder, such that, provided the Company’s reasonably determines that it has received at least $65.0 million in gross proceeds from the sale of its Common Stock from one or more of the holders that consented to the Supplemental Indentures (the “Specified Equity Raise”), the holders of the Notes may elect to convert their respective Notes at a reduced conversion price of $3.116 in the case of the June 2022 Notes and $3.116 in the case of the June 2023 Notes for a limited period of time (after which time, the reduced conversion prices will no long apply), and (ii) the addition of a beneficial ownership limitation such that no conversion of any Notes shall result in a then-ownership by such holder and its affiliates of over 9.9% of the outstanding shares of the Company’s common stock or combined voting power of the Company’s voting securities immediately after giving effect to the conversion.
