. holder will recognize gain or loss on the sale or other taxable disposition of a Series B Warrant in an amount equal
to the difference, if any, between (a) the amount of cash plus the fair market value of any property received and (b) such U.S. holder’s tax basis in the Series B Warrant sold or otherwise disposed of. Any such gain or loss generally
will be a capital gain or loss, which will be long-term capital gain or loss if the Series B

S-28

Warrant is held for more than one year. Long-term capital gains recognized by certain non-corporate U.S. holders (including individuals) generally will be
subject to a current maximum tax rate of 20%. Deductions for capital losses are subject to complex limitations under the Code.

Expiration of Series B Warrants without Exercise

Upon the expiration of a Series B Warrant, a U.S. holder will recognize a loss in an amount equal to such
U.S. holder’s tax basis in the Series B Warrant. Any such loss generally will be a capital loss and will be long-term capital loss if the Series B Warrant is held for more than one year. Deductions for capital losses are subject to complex
limitations under the Code.

Certain Adjustments to the Series B Warrants

Under Section 305 of the Code, an adjustment to the number of Warrant Shares that will be issued on the exercise of the Series B Warrants,
or an adjustment to the exercise price of the Series B Warrants, may be treated as a constructive distribution to a U.S. holder of the Series B Warrants if, and to the extent that, such adjustment has the effect of increasing such U.S.
holder’s proportionate interest in our “earnings and profits” or assets, depending on the circumstances of such adjustment (for example, if such adjustment is to compensate for a distribution of cash or other property to our
shareholders). Such constructive distribution would be subject to tax in the same manner as if such U.S. holder received a cash distribution from us equal to the fair market value of such increased interest. In addition, a U.S. holder’s tax
basis in a Series B Warrant will generally be increased to the extent of any such constructive distribution that is treated as a dividend for United States federal income tax purposes. See the more detailed discussion of the rules applicable to
distributions made by us at “Consequences to U.S. Holders of the Acquisition, Ownership and Disposition
