IMPORTANT INFORMATION

The Offer is not being made to (and acceptance forms will not be accepted from or on behalf of) persons domiciled in Australia, Canada, Hong Kong, Japan, New Zealand, South Africa, or whose participation in the Offer requires that additional offer documents are prepared or registrations effected or that any other measures are taken in addition to those required under Swedish law (including Nasdaq Stockholm’s Takeover Rules), unless an exemption applies.

This application form and any other documentation related to the Offer (including copies of such documentation) must not be mailed or otherwise distributed, forwarded or sent in or into any jurisdiction (including, without limitation, Australia, Canada, Hong Kong, Japan, New Zealand or South Africa) in which the distribution of this application form or the Offer would require any additional measures to be taken or would be in conflict with any laws or regulation in any such jurisdiction. Persons who receive this application form (including, without limitation, banks, brokers, dealers, nominees, trustees and custodians) and are subject to the laws or regulations of any such jurisdiction will need to inform themselves about, and observe, any applicable restrictions and requirements. Any failure to do so may constitute a violation of the securities laws or regulations of any such jurisdiction.

* NID number requirements for natural persons

The National Client Identifier (NID) is a global identifier for individuals that is mandatory in securities transactions. If you only have Swedish citizenship, your NID number consists of the designation “SE” followed by your personal identity number. If you have more than one or something other than Swedish citizenship, your NID number can be some other type of number. For more information on how to obtain NID numbers, please contact your bank branch. Remember to find out your NID number well in advance as the number needs to be stated on the application form.

** LEI code requirements for legal entities

Legal Entity Identifier (LEI) is a global identifier for legal entities that is mandatory in securities transactions. Remember to apply for registration of an LEI code with sufficient time if it is not held as the code needs to be stated on the application form. More information about the LEI requirements can be found on the Swedish Financial Supervisory Authority’s website www.fi.se.

Information on the processing of personal data

Those who accept the Offer will provide personal data to SEB. Personal data provided to SEB will be processed in computer systems to the extent necessary to administer the Offer. Personal data obtained from sources other than the customer may also be processed. Information regarding the processing of personal data can be obtained from SEB’s offices, which also accept requests for correction of personal data. Personal data may also be processed in the computer systems of companies with which SEB cooperates. The address details may be obtained by SEB through an automated procedure performed by Euroclear.

Other information

SEB Issues will perform certain administrative services in relation to the Offer. This does not in itself mean that a person who accepts the Offer (“Participant”) is considered a customer of SEB. Upon acceptance of the Offer, the Participant is considered a customer only if SEB has advised the Participant. If the Participant is not regarded as a customer, the rules on investor protection in the Securities Market Act (2007:528) do not apply to the participant’s acceptance. This means, among other things, that neither so-called customer categorization nor so-called suitability assessment will take place with regards to the Offer.

The participant is therefore solely responsible for ensuring that he/she has sufficient experience and knowledge to understand the risks associated with the Offer.
