In connection with the offering, iBio issued (i) pre-funded warrants (the "Pre-Funded Warrants") to purchase 71,540,000 shares of iBio’s common stock, and (ii) accompanying Series G warrants (the "Series G Warrants") representing the right to purchase (a) 35,770,000 shares of iBio’s common stock, or pre-funded warrants in lieu thereof, and (b) Series H warrants (the "Series H Warrants") representing the right to purchase 35,770,000 shares of iBio’s common stock, or pre-funded warrants in lieu thereof. The combined public offering price of one Pre-Funded Warrant and one Series G Warrant to purchase (i) one-half of a share of iBio’s common stock, or a pre-funded warrant in lieu thereof, and (ii) one Series G Warrant to purchase one-half of a share of iBio’s common stock, or a pre-funded warrant in lieu thereof, was $0.699.

The Pre-Funded Warrants are, and the pre-funded warrants issuable upon exercise of the Series G Warrants and Series H Warrants will be, immediately exercisable and exercisable until exercised in full. The Series G Warrants and Series H Warrants are immediately exercisable from their date of issuance and have an exercise price equal to $0.70 per share of iBio’s common stock (or $0.699 per pre-funded warrant) and in the case of the Series G Warrants, the accompanying Series H Warrant. The Series G Warrants will expire on the date that is the earlier of (i) 30 trading days following iBio’s public announcement, via a press release on a nationally recognized news wire or the filing of a Current Report on Form 8-K with the Securities and Exchange Commission (the "SEC"), that an Investigational New Drug Application ("IND") filed with the U.S. Food and Drug Administration, a Clinical Trial Notification filed with the applicable foreign governmental body in Australia, a Clinical Trial Application filed with the European Medicines Agency, or an equivalent submission filed with a foreign governmental body to initiate a clinical trial in any other foreign jurisdiction has been accepted or has otherwise gone into effect, as applicable (such public filing or announcement, the "Trial Initiation Milestone") and (ii) five years from the date of issuance. In addition, each Series G Warrant will immediately expire in proportion to the extent that the corresponding Pre-Funded Warrant held by a holder is exercised prior to the occurrence of the Trial Initiation Milestone (solely to the extent the proportion of the unexercised portion of the Series G Warrant relative to the originally issued Series G Warrant is greater than the proportion of the unexercised portion of the Pre-Funded Warrant relative to the originally issued Pre-Funded Warrant). When issued upon exercise of the Series G Warrants, the Series H Warrants will expire on the four-year anniversary of the closing date of the offering.
