Avantium Launches Initial Public Offering on Euronext Amsterdam (y 2)

The Securities have not been and will not be registered under the U.S. Securities Act of 1933, as amended (the "Securities Act") and may not be offered or sold in the United States unless registered under the Securities Act or an exemption from such registration is available. No public offering of Securities of the Company is being made in the United States. This communication is directed at and distributed only to (i) persons outside the United Kingdom, or (ii) persons having professional experience in matters relating to investments who fall within the definition of "investment professionals" in Article 19(5) of the Financial Services and Markets Act 2000 (Financial Promotion) Order 2005 or (iii) high net worth companies, unincorporated associations and partnerships and trustees of high value trusts as described in Article 49(2) of the Financial Services and Markets Act 2000 (Financial Promotion) Order 2005. Any investment or investment activity to which this communication relates is available only to and will be engaged in only with such persons.

In connection with the offering, Fortis Bank (Nederland) N.V. (the "Stabilization Manager") (or persons acting on behalf of the Stabilization Manager) may over-allot shares or effect transactions with a view to supporting the market price of the Securities at a level higher than that which might otherwise prevail. However, there is no assurance that the Stabilization Manager (or persons acting on behalf of the Stabilization Manager) will undertake stabilization action. Any stabilization action may begin on or after the date on which adequate public disclosure of the final offer price of the Securities is made and, if begun, may be ended at any time, but it must end no later than 30 days after allotment of the Securities.

All investment is subject to risk. The value of the Securities offered may go down as well as up. Past performance is no guarantee of future returns. Potential investors are advised to seek expert financial advice before making any investment decision.
