In May 2008, OMX Nordic Exchange will commence post trade anonymity in trading.

The Helsinki and Iceland markets will implement post trade anonymity to all
equity-related markets including First North. In Stockholm, this concerns the
five most traded shares. Following the introduction of post trade anonymity, the
member identity is removed from the market data feed and SAXESS trade ticker.

Where as OMX Nordic Exchange Helsinki and Iceland will implement post trade
anonymity in all equity-related markets including First North, the Nordic
Exchange in Stockholm will introduce post trade anonymity in the five most
traded shares, which currently are Ericsson B, Volvo B, TeliaSonera, Nordea, and
H&M B. These five shares represent 33 percent of the total turnover in Stockholm

attract automated trading volumes," says Jukka Ruuska, President of Nordic
Marketplaces at OMX.

Post trade anonymity is a standard in all major European and U.S. exchanges, and
its adoption is expected to further increase the efficiency of securities
