Delisting

As a result of the Offeror holding more than 95% of the Securities, the Offeror and Brill intend to procure the delisting of the Depository Receipts from Euronext Amsterdam as soon as possible under applicable rules.

Reference is made to Section 5.11 (Consequences of the Offer for Minority Securityholders) of the Offer Memorandum.

Further implications of the Offer being declared unconditional

Remaining Securityholders who do not wish to tender their Securities under the Offer in the Post-Closing Acceptance Period should carefully review, inter alia, Section 5.11 (Consequences of the Offer for Minority Securityholders), which describes implications to which such Securityholders may become subject in the event such Securityholders remain a Securityholder in Brill.
