The combined businesses will be called Nyrstar and will be the world's pre-eminent zinc metal producer with operations on four continents, producing some 1.2 million tonnes of zinc and zinc alloys per year and employing some 4,500 people. It is anticipated that Nyrstar would come into existence during September 2007 subject to Zinifex shareholder approval, which will be sought in July, and the satisfaction of certain other conditions, including relevant regulatory approvals - most of which have been obtained - and no material adverse change occurring with respect to Umicore's or Zinifex's zinc smelting and alloying business. It is the intention to undertake an initial public offering of shares in the new enterprise at an appropriate time thereafter. Umicore and Zinifex shares in Nyrstar will be approximately 40% and 60% respectively, reflecting the relative value of the contributed assets. Final shares will still be subject to adjustment at the formation of Nyrstar but it is not expected that there would be any significant difference from the percentages advised above. Until such time as the IPO occurs, however, the initial joint venture will be structured on an equal ownership basis with an appropriate equalisation payment being made to Zinifex from debt raised by the joint venture company. Due to Thai regulations with regard to foreign ownership, Umicore has elected to limit the contribution to Nyrstar of its stake in Padaeng Industry to 24.9%. The parties will seek to transfer Umicore's remaining interest of 22% in Padaeng Industry to Nyrstar prior to its formation, in line with the regulatory processes in Thailand. It is the intention of Umicore and Zinifex that Nyrstar would operate as an independent entity from its inception with its own Board of Directors and Executive Committee. The jointly owned company would be incorporated in Belgium and have its head office in London. The chairman elect for Nyrstar is Julien De Wilde, former CEO of Bekaert. Also joining the Nyrstar board as directors elect are Karel Vinck (Chairman of Umicore) and Peter Mansell (Chairman of Zinifex). Further board members will be designated in due course. As previously advised, Paul Fowler will assume responsibility for the formation of Nyrstar as Chief Executive Officer elect, and will stand down immediately as Chief Operating Officer at Zinifex. Similarly, Heinz Eigner, will relinquish his duties as Controller of the Zinc Specialties business group at Umicore to become Chief Financial Officer elect. Other executive management will be drawn jointly from the two companies. The Zinifex assets to be contributed are the Hobart (Australia), Port Pirie (Australia), Clarksville (USA) and Budel (Netherlands) smelting and alloying operations as well as its shareholdings in Australian Refined Alloys (Australia) and Genesis Alloys (China). The Umicore assets to be contributed are the Balen (Belgium), Overpelt (Belgium), Auby (France) and GM Metal (France) smelting and alloying operations as well as its shareholdings in, Galva 45 (France), Umicore Yunnan Zinc Alloys (China), F?hl China (China) and 24.9% of Padaeng Industry (Thailand). Under the terms of the BCSA, both companies have agreed not to pursue competing transactions or to permit due diligence investigations to be undertaken by third parties in relation to the assets planned to be contributed to Nyrstar. However, these restrictions will not apply if either company receives an unsolicited, superior proposal which would prevent the new venture from taking place. If either company solicits a competing proposal or terminates the BCSA as a result of receiving a superior proposal, a break fee of Euro 10 million is payable.

About Nyrstar Pronounced 'Neer Star', the name is derived from the Old Norse word 'nyr', meaning new, and the English word 'star', which of course is used to describe a mark of excellence, distinction or taking a leading role. The name conjures up an image of a new company characterised by energy and brilliance. Nyrstar will indeed aim to be a new star in its industry.
