• Rocket declares the Offer unconditional.

With reference to the Offer Memorandum, Rocket, will pay, no later than 27 April 2007 (the “Settlement Date”), an amount of EUR 4.33 in cash for each share validly tendered (or defectively tendered provided that such defect has been waived by Rocket) and delivered (“Offer Price Per Share”). Admitted Institutions to Euronext Amsterdam N.V. must deliver tendered shares to Fortis Bank as Settlement Agent by 26 April 2007 at the latest.

As more than 95 percent of the issued and outstanding share capital of Seagull has been tendered, it is Rocket’s intention to, after consultation with Euronext Amsterdam N.V., terminate Seagull’s listing on Euronext Amsterdam N.V. and to initiate a statutory squeeze-out procedure (uitkoopprocedure) as provided for in section 92a of book 2 of the Dutch Civil Code as soon as legally practicable.

The Offer is not being made, and the shares will not be accepted for purchase from or on behalf of any shareholders in any jurisdiction in which the making or acceptance thereof would not be in compliance with the securities or other laws or regulations of such jurisdiction or would require any registration, approval or filing with any regulatory authority not expressly contemplated by the terms of the Offer Memorandum. Neither Rocket nor Seagull nor any of their advisors accepts any liability for any violation by any person of any such restriction. However, acceptances of the Offer by shareholders not resident in the Netherlands will be accepted by Rocket if such acceptances comply with the acceptance procedure set out in the Offer Memorandum.

This press release is a public announcement as meant within article 9b paragraph 1 of the Decree on the Supervision of the Securities Trade 1995 (Besluit toezicht effectenverkeer 1995).
