 Series B Warrant and related receipt of a Warrant Share. A non-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 non-U.S. holder’s tax basis in such Series B Warrant plus (b) the
exercise price paid by such non-U.S. holder on the exercise of such Series B Warrant. It is unclear whether a non-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 non-U.S. holder or the day following the date of exercise of the Series B Warrant.

In certain limited circumstances, a non-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 for the reasons described above under “Consequences to U.S. Holders—Consequences to U.S. Holders of the Exercise, Expiration and Disposition of Series B Warrants—Exercise of Series B Warrants,” and the tax consequences of a cashless exercise could differ from the consequences upon
the exercise of a Series B Warrant described in the preceding paragraph. However, if, as described above under “Consequences to U.S. Holders—Consequences to U.S. Holders of the Exercise, Expiration and Disposition of Series B Warrants—Exercise of Series B Warrants,” the cashless exercise of the Series B Warrants were recharacterized in part as a taxable exchange, the consequences to a non-U.S. holder would generally
be the same as those described below under “Consequences to Non-U.S.Holders of the Acquisition, Ownership and Disposition of Shares of Common Stock, Pre-fundedWarrants and Warrant Shares—Sale, Taxable Exchange or Other Taxable Dispositions of Shares of Common Stock, Warrants and Warrant Shares.” Non-U.S. holders are urged to consult their own
tax advisors regarding the United States federal income tax consequences of a cashless exercise of Warrants.
