 at the time such payment is made and generally should equal to the excess of (i) the amount of the payment in respect of
the Contingent Payment Right over (ii) the present value of such amounts of the Closing Date of the Mergers, calculated using the applicable federal rate for the calendar month which includes such Closing Date as the discount rate.

Sale or Other Disposition of the rights to the Contingent Payment Amounts

Upon a sale or other disposition of the rights to the Contingent Payment Amounts, the U.S. federal income tax consequences of such sale or
other disposition is uncertain, and depends on the characterization of the Mergers, including the receipt of such rights as part of an “open transaction” or “closed transaction” for U.S. federal income tax purposes, and also
depends on the nature of such sale or other disposition. Therefore, U.S. holders are urged to consult their own tax advisors in connection with any such sale or other disposition of such rights.

If the Mergers do not qualify as a
“reorganization” within the meaning of Section 368 of the Code, a U.S. Holder generally would recognize gain or loss for U.S. federal income tax purposes on each share of Kineta Common Stock surrendered in the Mergers. The amount of
gain a U.S. Holder recognizes, and the timing and character of such gain, is subject to the same uncertainty described above as to whether the transaction should be treated as a “closed transaction” or an “open transaction” for
U.S. federal income tax purposes.

Under open transaction treatment, the fair market value, at the effective time of the Mergers, of the
TuHURA Common Stock received in the Mergers (including any cash received in lieu of a fractional shares of TuHURA Common Stock), plus any other cash received at the time
