Pre-Funded Warrants Exercisability. The pre-funded warrant held by the Reporting Persons is exercisable at any time after its original issuance. Exercise Blocker. Exercise of each pre-funded warrant is prohibited if, as a result of such exercise, the holder, together with its affiliates and other persons whose beneficial ownership would be aggregated with the holder's for purposes of Section 13(d) of the Act, would beneficially own more than 9.99% of the total number of shares of Common Stock then issued and outstanding immediately after giving effect to the exercise (the "Beneficial Ownership Blocker"). Exercise Price. The Reporting Persons hold pre-funded warrants exercisable for up to 7,047,216 shares of Common Stock with an exercise price of $0.001 per share. The exercise price is subject to appropriate adjustment in the event of certain stock dividends and distributions, stock splits, stock combinations or reclassifications affecting the Common Stock. Fundamental Transaction. If a Fundamental Transaction (as defined in the pre-funded warrant) occurs while a pre-funded warrant is outstanding, then upon any subsequent exercise of the pre-funded warrant, the holder thereof has the right to receive the same amount and kind of securities, cash or property as such holder would have been entitled to receive upon the occurrence of such Fundamental Transaction if it had been, immediately prior to such Fundamental Transaction, the holder of the number of shares of Common Stock then issuable upon exercise in full of the pre-funded warrant (without regard to any limitations on exercise). Rights as a Stockholder. Except as otherwise provided in the pre-funded warrant or by virtue of the holder's ownership of Common Stock, the holder of a pre-funded warrant does not have the rights or privileges of a holder of Common Stock, including any voting rights, until the holder exercises the pre-funded warrant.
