Approval of the resolution of the Board of Directors on a preferential rights issue (item 7 on the agenda)

On 14 February 2006, the Board of Directors resolved to increase the company's share capital with a maximum of SEK 94,188,948 by a new issue of not more than 1,050,000 shares of class A and not more than 22,497,237 shares of class B with a preferential right of the present shareholders. Shareholders of class A and B shares will have primary preferential right to subscribe for shares of the same class in proportion to their previous shareholdings.

Shares not subscribed for with primary preferential right will be offered all shareholders for subscription (secondary preferential right). If the number of shares issued are not sufficient to cover the number of shares subscribed for with secondary preferential right, the shares will be allotted between the subscribers in proportion to their previous shareholdings and to the extent that is not possible, by drawing of lots. Subscription for shares without primary or secondary preferential rights cannot be made.

Subscription by the exercise of option rights issued in 2003 shall be made by 7 March 2006 in order to invest the holder of such shares with the right to participate in the issue.

The record day at the Swedish Securities Register Centre (Sw: "VPC AB") for participation in the preferential rights issue shall be 22 March 2006. The Board of Directors or anyone appointed among the members of the Board of Directors shall, no later than three days prior to the record date, be authorised to determine the maximum amount that the company's share capital can be increased with and the price to be paid for each new share. Subscription for the new issued shares shall take place during the subscription period as of 27 March until 12 April 2006, or such later date as decided by the Board of Directors. Subscription by the exercise of subscription rights shall be made by contemporaneous cash payment. Payment for shares without subscription rights shall be made in cash not later than 26 April 2006, or such later date as decided by the Board of Directors.

The new shares will entitle to dividends as of the financial year 2006, i.e. also for the financial year 2005.

The Board of Directors proposes that the Shareholders' Meeting approves the resolution of the Board of Directors.
