Dividend Payment Date (SA) Thursday, 3 CSDP accounts credited on the South Africa Register November Expected date of issue, admission and first day of dealings in the New Shares on the JSE Notes: 1. The scrip share reference price is calculated by taking the average of the middle market quotations for Shares on the LSE (for shareholders on the UK register) or the JSE (for shareholders on the SA register) for the last five dealing days ending on the Currency Conversion Date less the gross value of the cash Dividend per Share. 2. For Shareholders on the UK Register, entitlements to fractions of New Shares will be paid based on the value of the Enhanced Scrip Dividend Alternative. 3. The cash fraction reference price for shareholders on the South Africa register is determined by taking the volume weighted traded price on the JSE on the date at which the Shares begin trading on the JSE ex the cash dividend or Enhanced Scrip Dividend Alternative, discounted by 10%. 4. The transfer of shares to and from the UK principal register and the SA branch register will not be permitted between Wednesday, 5 October 2022 to Friday, 7 October 2022, both dates inclusive. 5. Shareholders registered on the South Africa Register should note that, in accordance with the requirements of Strate, no dematerialisation or rematerialisation of shares will be possible from Wednesday, 5 October 2022 and the close of business on Friday, 7 October 2022, both dates inclusive. 6. Securities transfer tax will not be payable in respect of the issue of New Shares to South African Shareholders. 7. Shareholders registered on the SA branch register will be paid in SA Rand. 8. A summary of how UK Shareholders and South Africa Shareholders are likely to be treated for tax purposes will be set out in Section 2 of the Guide containing the terms and conditions of the Enhanced Scrip Dividend Alternative, which will be made available to Shareholders on Wednesday, 28 September 2022. The effect on a 3 Shareholder's tax position of electing to receive New Shares instead of cash in respect of the Interim 2022 Dividend will depend upon the personal circumstances of that Shareholder. If you are in any doubt as to your tax position or you are subject to tax in a jurisdiction outside the UK or South Africa (including the Republic of Ireland), you should consult an appropriate professional adviser before taking any action. 9. As the Company is offering the Enhanced Scrip Dividend Alternative for the Interim 2022 Dividend, it intends to suspend the Dividend Reinvestment Plan ("DRIP"). Participation in the DRIP does not confer automatic participation in the Enhanced Scrip Dividend Alternative and so participants in the DRIP who wish to receive the Enhanced Scrip Dividend Alternative will need to elect to participate in the Enhanced Scrip Dividend Alternative by the applicable election process described above. 10. Please note that all previously completed forms of election or other forms of instruction in respect of earlier scrip dividend schemes (including the final 2021 dividend paid in May 2022) have been cancelled. Any Shareholder wishing to participate in the Enhanced Scrip Dividend Alternative must therefore complete a new Form of Election or elect to participate in the Enhanced Scrip Dividend Alternative. 11. The cash element of the Interim 2022 Dividend will be paid out of the Company’s UK distributable reserves. It is intended that the nominal value of the new shares issued to shareholders who validly elect to participate in the Enhanced Scrip Dividend Alternative will be funded by utilising the Company's share premium account. 12. The dates above are subject to change. Any changes made will be communicated as soon as practicably possible.
