 and Warrants

For United States federal income tax purposes, a holder’s acquisition of a share of common stock (or a Pre-funded Warrant) and two Series B Warrants pursuant to this offering will be treated as the acquisition of an “investment unit” consisting of one share of common stock (or one Pre-funded Warrant, which, as described above, should generally be treated as a share of common stock for United States federal income tax purposes) and two Series B Warrants, with each Series B Warrant allowing the
holder to purchase one share of our common stock. The purchase price for each investment unit will be allocated between these components in proportion to their relative fair market values at the time the unit is purchased by the holder. This
allocation of the purchase price for each unit will establish the holder’s initial tax basis for United States federal income tax purposes in the common stock (or Pre-funded Warrant) and the Series B
Warrants included in each unit. We do not intend to advise holders of the securities with respect to this determination, and holders of the securities are advised to consult their tax and financial advisors regarding the allocation of the purchase
price for United States federal income tax purposes.

Consequences to U.S. Holders of the Exercise, Expiration and Disposition of Series B Warrants

Exercise of Series B Warrants

A U.S.
holder generally will not recognize gain or loss on the exercise of a Series B Warrant and related receipt of a Warrant Share. A U.S. holder’s initial tax basis in the Warrant Share received on the exercise of a Series B Warrant generally will
be equal to the sum of (a) such U.S. holder’s tax basis in such Series B Warrant plus (b) the exercise price paid by such U.S. holder on the exercise of such Series B Warrant. It is unclear whether a U.S. holder’s holding
period for the Warrant Share received on the exercise of a Series B Warrant should begin on the date that such Series B Warrant is exercised by such U.S. holder or the day following the date of exercise of the Series B Warrant.

In certain limited circumstances, a U.S. holder may be required or permitted to undertake a cashless exercise of Series B Warrants into
Warrant Shares. The United States federal income tax treatment of a cashless exercise of Series B Warrants into Warrant Shares is unclear, and the tax consequences
