OKMETIC OYJ STOCK EXCHANGE RELEASE 15 MARCH 2007 1(1) TECHNOLOGY SALE AGREEMENT BETWEEN OKMETIC AND NORSUN FINALISED In summer 2006, Okmetic sold its crystal growth technology to NorSun AS, a Norwegian solar energy enterprise. The deal is worth 15 million euro over a period of three years and Okmetic is expecting to see the peak of the resulting profits in 2008 and 2009. Okmetic will enter the 1.0 million euro advance payment that was received last year as revenue during the current quarter. According to the agreement that Okmetic and NorSun AS signed in June 2006, Okmetic will increase its crystal growth capacity at its plant in Vantaa. NorSun will fund the additional production machinery, and Okmetic will pay for the building work required for extending the plant and then begin to grow crystals on behalf of NorSun.

The total investment in the Vantaa plant extension will amount to around 10 million euro, and Okmetic's share of the investments will be worth around 2.7 million.

The construction work on the extension of the Vantaa plant, which got underway in autumn 2006, will be completed in the summer, and production is expected to start by the end of the year once all the machinery has been installed.
