The consideration was satisfied by way of an immediate cash payment of US$54.0 million (GBP31.4 million*), with an additional US$1.5 million (GBP0.9 million*) to be paid upon closing of the sale of the SCS China business in early 2006. The consideration will be subject to completion balance sheet adjustments in respect of working capital and capital expenditure, which are not expected to be material. The sale of SCS is part of Cookson's strategy of achieving progressive debt reduction through, in part, non-core business disposals, and brings the proceeds from disposals agreed in 2005 up to the GBP100 million targeted by the end of 2006. SCS comprises a group of companies and business assets with its main operations in the USA, Europe and Asia-Pacific. Its primary business is the service application of a specialty conformal coating product principally for use in automotive, electronic and medical applications. On an International Financial Reporting Standards ("IFRS") basis, for the year ended 31 December 2004, SCS generated a trading profit** of GBP4.3 million on revenue of GBP19 million. As at 31 December 2004, SCS had gross assets of GBP18 million and gross liabilities of GBP2 million. For the six months ended 30 June 2005, SCS generated a trading profit** of GBP2.1 million on revenue of GBP9 million. As at 30 June 2005, SCS had gross assets of GBP19 million and gross liabilities of GBP2 million and employed 285 people. The net cash proceeds from the sale will strengthen Cookson's balance sheet and provide greater financial flexibility. Additionally, Cookson will consider making advanced payments into its UK pension scheme to reduce the existing deficit. In January 2005, Cookson announced a target of raising over GBP100 million from disposal proceeds by the end of 2006. In the six month period to 30 June 2005, proceeds from disposals totalled GBP13 million. Furthermore, on 15 December it was announced that a conditional agreement had been entered into to sell Cookson's Laminates business for US$91 million (GBP53 million*). On completion of that disposal (expected in February 2006) together with some further property disposals completed recently and including the proceeds from this transaction, Cookson will have generated disposal proceeds of over GBP100 million. Commenting on the sale of SCS, Nick Salmon, Chief Executive of Cookson Group plc, said: "SCS is a good quality business, as reflected in the price achieved. However, it does not fit strategically with our core electronics business, and the sale represents further significant progress in terms of our strategy of progressive debt reduction. Following the recent announcement regarding the sale of our Laminates business, this deal means we have achieved our strategic goal of raising GBP100 million through disposals, a year ahead of schedule. "Our strategic plan also involves achieving significant improvements in profitability, and our third quarter trading update in early November demonstrated that we are making solid progress in this regard as well."

Cookson's objectives include improving profitability, with targeted return on sales by 2007 of 10% in both the Ceramics and Electronics divisions and a return on net sales value (i.e. excluding the precious metals content) of 15% for the Precious Metals division. Cookson also plans to reduce total debt significantly over the next 2-3 years. This will be achieved through a combination of strong operational cash flow - from improved profitability and working capital management - and a disposal programme which will raise over GBP100 million from the sale of a number of non-core activities and assets by the end of 2006. In addition, Cookson intends to resume a sustainable dividend payment as soon as possible with dividends funded from free cash flow.

FOURTH QUARTER TRADING UPDATE Cookson Group plc ("Cookson"), the leading materials science company, is issuing this trading update ahead of its full year results for 2005, scheduled for announcement on 14 March 2006. Fourth Quarter Highlights: o Better than expected trading performance from the Ceramics and Electronics divisions; Precious Metals division's weak trading continued o Disposal proceeds target of GBP100 million reached ahead of schedule o Recently announced disposals: - Disposal of Laminates business for US$91 million (GBP53 million*) - Disposal of SCS for US$55 million (GBP32 million*) Commenting on the fourth quarter, Nick Salmon, Cookson's Chief Executive, said: "We continue to make good progress in implementing the strategic plan announced last January. Fourth quarter trading has been ahead of the expectations indicated in our 4 November Trading Update, due to strong performances from our two largest divisions, Ceramics and Electronics. The full year results will show that these divisions, post the disposals, have made substantial progress towards achieving the targeted margin levels. With the two disposals signed in December we have now reached our disposal target of GBP100 million." Trading The Ceramics division performed significantly ahead of expectations in the fourth quarter with steel volumes in Europe and the USA better than previously anticipated and a robust performance from the Glass sector. Trading profit for the fourth quarter is now expected to be higher than that recorded for the third quarter. Trading in our Electronics division was also ahead of expectations due to a strong performance from the Assembly Materials sector, benefiting from the continued pick up in the lead free solder market. The Precious Metals division continued to experience weak market conditions, most particularly in the UK, with a weaker seasonal up-tick than in prior years. The Group now expects its overall performance for 2005 to be ahead of its previous expectations. Cash generation for the fourth quarter has been satisfactory, although the year end net debt level has been negatively impacted by the strengthening of the US dollar. Overall net debt at 31 December 2005 is expected to be slightly below GBP300 million. This includes the SCS disposal proceeds of GBP31.4 million received at the year end but has been negatively impacted by an approximately GBP32 million exchange rate movement effect in the year. Restructuring During the fourth quarter several new restructuring initiatives were launched, targeted at reducing operating expenses and exiting certain commodity activities. The related charges will be booked in 2005, taking the total restructuring charge in the year towards GBP20 million. The cash spend in 2005 relating to these initiatives, plus those launched in previous years, is also expected to be approximately GBP20 million. Disposals In January 2005, Cookson announced a target of raising over GBP100 million from disposal proceeds by the end of 2006. The disposal programme is part of Cookson's strategy of focussing on higher technology products and exiting commodity activities, as well as achieving progressive debt reduction. On 15 December 2005, the disposal of Cookson's Laminates business for US$91 million (GBP53 million*) was announced which is conditional upon clearance from the competition authorities in Europe. Due to some delays by the acquirer in submitting the merger filings, this clearance is now not expected before the end of March 2006. In addition, on 3 January 2006 Cookson announced that it had disposed of its SCS business on 31 December 2005 for US$55.5 million (GBP32 million*). On completion of the Laminates transaction and including the cash proceeds from property and other disposals in the twelve month period to 31 December 2005, Cookson will have generated disposal proceeds of over GBP100 million. Laminates and SCS will be reported as 'discontinued operations' in the 2005 financial statements. Pension Deficit The reduction in December in the long term corporate bond rate used in the calculation of UK pension fund liabilities means the pension deficit will increase over the amount stated in the Interim Results. A full revaluation of the UK pension scheme is not yet available but we expect the increase in the deficit between 1 July and 31 December 2005 to be in the order of GBP20 million. Other The Company's Extraordinary General Meeting on 12 January will be seeking shareholder approval for changes to its Articles of Association as part of the planned termination of the registration of its ordinary shares with the USA Securities and Exchange Commission and to effect a reduction of its share capital. Cookson expects to announce the preliminary results for the year ended 31 December 2005 on 14 March 2006. Note * Translated at an exchange rate of GBP1 to US$1.718.

Exhibit No.8 12 January 2006 Cookson Group plc Results of Extraordinary General Meeting Cookson Group plc ("Cookson" or the "Company") announces that the special resolutions proposed to holders of the Company's ordinary shares of 10 pence each ("shareholders"), and as detailed in the circular sent to shareholders on 19 December 2005, were duly passed at today's Extraordinary General Meeting. The resolutions were: - to amend the Company's Articles of Association to facilitate termination of its registration with the US Securities and Exchange Commission ("SEC"); - to reduce the issued share capital of the Company by cancelling and extinguishing the deferred shares of 49 pence each; - to reduce the authorised share capital of the Company by cancelling and extinguishing six ordinary shares of 1 pence each; and - to cancel the share premium account of the Company. The amendment to the Articles of Association includes a provision conferring upon the Board the power to require ordinary shares which are held directly or indirectly by US resident shareholders to be sold in order to reduce the number of such shareholders to below 300, as presently required by the SEC for termination of registration. In order to avoid the costs of complying with SEC registration requirements in respect of the financial year ended 31 December 2005, the Board intends to commence exercising these compulsory transfer provisions as soon as reasonably practicable. Subject to legal, fiduciary and regulatory requirements and costs, the Board will take account of the relative size of the holdings of US resident shareholders and apply the power first to those US resident shareholders with the smallest holdings of ordinary shares. Subject to approval by the High Court, cancellation of the deferred shares and the other reductions of capital outlined above are expected to become effective on or around 15 February 2006 upon registration of the order of the High Court with the Registrar of Companies. Copies of the resolutions passed at the Extraordinary General Meeting will shortly be available for inspection at the UK Listing Authority's Document Viewing Facility, which is situated at: The Financial Services Authority 25 The North Colonnade Canary Wharf London E14 5HS Tel: +44 (0)20 7066 1000 Enquiries: Cookson Group plc Tel: +44 (0)20 7061 6500 Richard Malthouse, Group Secretary www.cooksongroup.co.uk SIGNATURE Cookson Group plc By:________________ Rachel Fell Assistant Company Secretary Date: 12TH JANUARY 2006
