 recognize a taxable loss (which loss would generally be a capital loss) for U.S. federal
income tax purposes at the time of the expiration of such rights in amount equal to the unrecovered tax basis of such holder in such Contingent Payment Rights as of such time. The deductibility of capital losses for U.S. federal income tax purposes
is subject to limitations. U.S. holders should consult with their own tax advisors regarding any such losses, including losses resulting from expiration of Contingent Payment Rights without any payments.

Open Transaction Treatment

The receipt
of the Contingent Payment Rights would generally be treated as part of an “open transaction” if the value of such rights cannot be “reasonably ascertained.” If the receipt of the Contingent Payment Rights were treated as an

Amounts are received or deemed received in accordance with the U.S. holder’s regular method of accounting, but only to the extent the sum of such payments (and all previous payments with respect to such Contingent Payment Rights) and the fair
market value other property received upon consummation of the Mergers (including any other cash and/or any TuHURA Common Stock), exceeds such U.S. holder’s adjusted tax basis in the Kineta Common Stock surrendered pursuant to the Mergers.

Imputed Interest with respect to payments pursuant to the Contingent Payment Rights

If a payment with respect to the Contingent Payment Rights is made more than one year after the consummation of the Mergers, a portion of the
payment may be treated as imputed interest for U.S. federal income tax purposes. Such imputed interest would be taxed as ordinary income to the recipient of such payment. If a portion of such payments with respect to the Contingent Payment Rights is
treated as imputed interest for U.S. federal income tax purposes, the amount of such imputed interest will be determined
