 be gain from U. S. sources for purposes of the foreign tax credit limitation; losses will
generally be allocated against U. S. source income. The deduction of capital losses is subject to certain limitations under the Code.

In the case of a cash-basis
U. S. Holder who receives Australian dollars in connection with the sale or other disposition of ADSs, the amount realized will be calculated
based on the U. S. dollar value of the Australian dollars received as determined by reference to the spot rate in effect on the settlement
date of such exchange. A U. S. Holder who receives payment in Australian dollars and converts Australian dollars into U. S. dollars
at a conversion rate other than the rate in effect on the settlement date may have foreign currency exchange gain or loss that would be
treated as ordinary income or loss from sources within the United States for U. S. foreign tax credit purposes.

An accrual-basis U. S. Holder
may elect the same treatment required of cash-basis taxpayers with respect to a sale or disposition of ADSs, provided that the election
is applied consistently from year to year. Such election may not be changed without the consent of the Internal Revenue Service (“ IRS”).
In the event that an accrual-basis U. S. Holder does not elect to be treated as a cash-basis taxpayer (pursuant to the Treasury regulations
applicable to foreign currency transactions), such U. S. Holder may have foreign currency gain or loss for U. S. federal income tax purposes
because of differences between the U. S. dollar value of the currency received prevailing on the trade date and the settlement date. Any
such currency gain or loss would be treated as ordinary income or loss from sources within the United States for U. S. foreign tax credit
purposes. However, if foreign currency is converted into U. S. dollars on the date received by the U. S. Holder, a cash-basis or electing
accrual-basis U. S. Holder should not recognize any gain or loss on such conversion.

Passive Foreign Investment Company rules

There is a risk that we may
be a passive foreign investment company(“ PFIC”), for U. S. federal income tax purposes. Our treatment as a PFIC could result
in a reduction in the after-tax return to the U. S. Holders of our ADSs and may cause a reduction in the value of such securities.
