PRELIMINARY INFORMATION ON F-SECURE CORPORATIONS SALES AND PROFITABILITY IN 2000

Espoo, Finland - January 19, 2001

According to preliminary information the consolidated net sales during the fourth quarter rose to approximately 12.5 million euros. This results in annual consolidated net sales of approximately 41.2 million euros. Net sales increased 15% from the previous quarter and 77% from 1999.

Growth of net sales was slowed down by a number of deals moving to future quarters, due to recent uncertainties in the North American market during the latter half of December. The deals moving forward affected predominantly encryption product sales. The duration and effects of market uncertainties are difficult to predict. However the company states that the competitiveness and demand for its products continue to be strong in North America as in the Rest of the World.

The sales of the company's products outside the North American market during the fourth quarter were in line with expectations. The potential for a recession has not affected the market for data security products in Europe and the company's sales are expected to grow as projected earlier.

The company's growth expectations for the whole year 2001 remain unchanged.

The group's operating loss for the last quarter will be higher than the operating loss for the third quarter. The operating loss for the fourth quarter will be in the range of 3.2 to 3.7 million euros. Option program related social security costs are not expected to impact the operating result during the fourth quarter.
