Notice to US investors in RBPlat The Offer will be made to RBPlat Shareholders in the United States in compliance with the applicable US laws and regulations, including Section 14(e) and Regulation 14E under the US Securities Exchange Act of 1934 as amended (the “Exchange Act”), and the exemptions from Regulation 14E and the U.S. tender offer rules provided by Rule 14d-1(c) under the Exchange Act. The Northam Holdings Shares being offered pursuant to the Offer have not been and will not be registered in the United States under the U.S. Securities Act of 1933, as amended (the “U.S. Securities Act”), or the securities laws of any state of the United States or other jurisdiction, and, subject to certain limited exceptions, may not be offered or sold, taken up, exercised, resold, renounced, transferred, delivered or distributed, directly or indirectly, in or into the United States absent of registration under the U.S. Securities Act and in compliance with any applicable state securities laws, or pursuant to an exemption from, or in a transaction not subject to, the registration requirements of the U.S. Securities Act. The financial information included in this announcement has been prepared in accordance with foreign accounting standards that may not be comparable to the financial statements of United States companies. It may be difficult for US holders of RBPlat Shares to effect service of process within the United States and to enforce their rights and any claim arising out of the US federal securities laws against RBPlat and/or Northam Holdings, since RBPlat and Northam Holdings are located in a non-US jurisdiction, and some or all of their officers and directors may be residents of a non-US jurisdiction. US holders of RBPlat Shares may not be able to sue a non-US company or its officers or directors in a non-US court for violations of the US securities laws. Further, it may be difficult to compel a non-US company and its affiliates to subject themselves to a US court’s judgement. Neither the Securities and Exchange Commission nor any securities commission of any state of the United States has approved the Offer, passed upon the fairness of the Offer or passed upon the adequacy or accuracy of this announcement. Any representation to the contrary is a criminal offence in the United States. RBPlat Shareholders in the United States should note that the Northam Holdings Shares are securities in a South African company, and the Offer is subject to South African procedural and disclosure requirements, rules and practices which are different from those of the United States and are proposed to be implemented by way of the Offer. You should be aware that Northam Holdings and its affiliates or brokers may purchase shares in RBPlat otherwise than under the Offer, such as in open market or privately negotiated purchases, to the extent permitted by, and in compliance with, Rule 14e- 5 under the Exchange Act and in accordance with South African law. Information about any such purchases or arrangements to purchase that is made public in accordance with South African law and practice will be available to all investors (including in the United States) via announcements on SENS.
