"Castellum is a strong company with high reputation, both as a player on the
Swedish property market as well as an investment alternative on the Swedish and
international capital markets. The company's strategy is based on financial
strength and a decentralized organization in combination with operational risk
diversification. The strategy was established in connection with the IPO 1997
and has since been consistently implemented and developed by three generations
of CEO's" says the Chairman of the Board Charlotte Strömberg.

"It has been fantastic to be involved all 18 years since Castellum was founded,
and as CEO the last 7 years. But I also feel that it is time to leave an
executive position and spend more time on other things than work-related issues"
comments CEO Håkan Hellström.

"I and the other members of the board would have liked to continue the
cooperation with Håkan as CEO and we are sorry to see him leave the company. We
thank Håkan for his valuable contribution to Castellum's development and at the
same time we also respect his will to leave the operational role. Until Håkan
leaves at the next AGM he and his management team has full support from the
board to continue implementing the strategy of the company. Castellum's
decentralized structure facilitates a smooth handover to a new CEO and
objectives and strategies will be implemented at the same pace as before, in
both long as well as short term" adds Charlotte Strömberg.

"The board now looks forward to complete the recruitment of Castellum's next CEO
and the process is expected to be completed well in time before the AGM"
concludes Charlotte Strömberg.

Meeting's decision. The election committee is formed by Maj-Charlotte Wallin
