Helsinki, Tallinn and Riga stock exchanges to adopt common Nordic cash trading platform On September 27, 2004, the Helsinki, Tallinn and Riga stock exchanges will harmonize their cash markets by adopting the SAXESS cash trading system already used by the Stockholm Stock Exchange, thus taking the next step in OMX’s vision of a fully integrated Nordic Baltic securities market. The cash market integration will generate benefits for members, enhance liquidity and promote trading in Finnish and Baltic equities. As a result of the integration, exchange members and investors will gain easy access to Finnish, Swedish and Baltic securities through one access point to the common trading system, and will also benefit from harmonized rules. The harmonization of cash markets is in line with the creation of one Nordic Baltic market and includes benefits such as: • Harmonized trading hours for the Helsinki and Stockholm stock exchanges (09:00-17:30 CET). • Harmonized trading day structure through the introduction of a closing call at the Helsinki, Tallinn and Riga stock exchanges. • Implementation of the NOREX Member Rules at the Helsinki Stock Exchange and the harmonization of the Tallinn and Riga rulebooks with NOREX Member Rules. • Introduction of a Joint Baltic Market with jointly marketed securities, harmonized listing rules between the Riga and Tallinn stock exchanges and a cross-border delivery-versus-payment link between the Estonian and Latvian CSDs. • BALTIX, the new pan-Baltic index. • RIGSE and VILSE, new capitalization-based total return indexes in Latvia and Lithuania. Through a wider Nordic cooperation, the NOREX alliance, securities from seven exchanges can be traded on the same platform with harmonized rules. The NOREX alliance is made up of the exchanges in Stockholm, Helsinki, Tallinn, Riga, Copenhagen, Oslo and Iceland.

The NOREX Member Rules are available at www.norex.com. As of September 27, the Helsinki Stock Exchange’s rulebook will consist of two parts: NOREX Member Rules and issuer rules. Compared to the current rules of the Helsinki Stock Exchange, there will be some changes including the lowering of the size limit for block trades in shares, in line with the other NOREX exchanges. Block trade rules will also be introduced for other equity instruments. The Tallinn and Riga stock exchanges will harmonize their current trading rules with NOREX trading and membership rules. The Joint Baltic Market The Tallinn, Riga and Vilnius stock exchanges will form a joint Baltic market to simplify access and minimize investment barriers when operating on Estonian, Latvian and Lithuanian markets.

Old Latvian and Lithuanian (except for LITIN-10) indexes will be discontinued.
