a PFIC may make a “qualified electing fund (QEF)” election under Section 1295(b) of the US Internal Revenue Code with respect
to such PFIC to elect out of the tax treatment discussed above. A U.S. Holder who makes a valid qualified electing fund election with
respect to a PFIC will generally include in gross income for a taxable year such holder’s pro rata share of the corporation’s
earnings and profits for the taxable year. The qualified electing fund election, however, is available only if such PFIC provides such
U.S. Holder with certain information regarding its earnings and profits as required under applicable U.S. Treasury regulations. We do
not currently intend to prepare or provide the information that would enable you to make a qualified electing fund election.

If a QEF election is available
with respect to any year that we are a PFIC by filing IRS Form 8621 with its U.S. federal income tax return. This election must be made
by the deadline (including extensions) for filing the U.S. Holder’s federal tax return for the year in question. U.S. Holders should
discuss their election alternatives with their own tax advisors. Once an election is made, the Electing Holder is subject to the QEF rules
for as long as we are a PFIC.

As an alternative to making
a QEF election, a U.S. Holder may make a “mark-to-market” election with respect to our Class A Ordinary Shares provided our
Class A Ordinary Shares are treated as “marketable stock.” The Class A Ordinary Shares generally will be treated as marketable
stock if they are regularly traded on a “qualified exchange or other market” (within the meaning of applicable Treasury Regulations)
on at least 15 days during each calendar quarter (other than in de minimis amounts).

If a U.S. Holder makes an
effective mark-to-market election, for each taxable year that we are a PFIC, the U.S. Holder will include as ordinary income the excess
of the fair market value of its Class A Ordinary Shares at the end of the year over its adjusted tax basis in the Class A Ordinary Shares.
You will be entitled to deduct as an ordinary loss in each such year the excess of your adjusted tax basis in the Class A Ordinary Shares
over their fair market value at the end of the year, but only to the extent of the net amount previously included in income as
