Notes

1 Please note that national forms may vary due to specific national legislation (Article 3(1a) of Directive 2004/109/EC) as for instance the applicable thresholds or information regarding capital holdings.

ii Full name of the legal entity and further specification of the issuer or underlying issuer, provided it is reliable and accurate (e.g. address, LEI, domestic number identity).

ii Other reason for the notification could be voluntary notifications, changes of attribution of the holding (e.g. expiring of financial instruments) or acting in concert.

ir This should be the full name of (a) the shareholder; (b) the natural person or legal entity acquiring, disposing of or exercising voling rights in the cases provided for in Article 9 (b) to (h) of the Transparency Law; or (c) the holder of financial instruments referred to in Article 12(1) of the Transparency Law.

As the disclosure of cases of acting in concert may vary due to the specific circumstances (e.g. same or different total positions of the parties, entering of acting in concert by a single party) the standard form does not provide for a specific method how to notify cases of acting in concert.

In relation to the transactions referred to in points (b) to (h) of Article 9 of the Transparency Law, the following list is provided as indication of the persons who should be mentioned:

• in the circumstances foreseen in letter (b) of Article 9 of that Law, the natural person or legal entity that acquires the voting rights and is entitled to exercise them under the agreement and the natural person or legal entity who is transferring temporarily for consideration the voting rights;

• in the circumstances foreseen in letter (c) of Article 9 of that Law, the natural person or legal entity holding the collateral, provided the person or entity controls the voting rights and declares its intention of exercising them, and natural person or legal entity lodging the collateral under these conditions;

• in the circumstances foreseen in letter (d) of Article 9 of that Law, the natural person or legal entity who has a life interest in shares if that person or entity is entitled to exercise the voting rights attached to the shares and the natural person or legal entity who is disposing of the voting rights when the life interest is created;

• in the circumstances foreseen in letter (e) of Article 9 of that Law, the controlling natural person or legal entity and, provided it has a notification duty at an individual level under Article 8, under letters (a) to (d) of Article 9 of that Law or under a combination of any of those situations, the controlled undertaking;

This should be the full name of the shareholder who is the counterparty to the natural person or legal entity referred to in Article 9 of that Law unless the percentage of voting rights held by the shareholder is lower than the 5% threshold for the disclosure of voting rights holdings (e.g. identification of funds managed by management companies).

vi The date on which threshold is crossed or reached should be the date on which the acquisition or disposal took place or the other reason triggered the notification. For passive crossings, the date when the corporate event took effect.

w The total number of voting rights shall be composed of all the shares, including depository receipts representing shares, to which voting rights are attached even if the exercise thereof is suspended.

will if the holding has fallen below the 5% threshold, please note that it is not necessary to disclose the extent of the holding, only that the new holding is below that threshold.

** The full chain of controlled undertakings starting with the ultimate controlling natural person or legal entity also has to be presented in the cases in which only on subsidiary level a threshold is crossed or reached and the subsidiary undertaking discloses the notification as only then the market always gets the full picture of the group holdings. In case of multiple chains through which the voting rights and/or financial instruments are effectively held the chains have to be presented chain by chain leaving a row free between different chains (e.g.: A, B, C, free row, A, B, D, free row, A, E, F etc.). Numbers shall be attributed to all persons or entities within the group in column 1 in order to allow a clear indication of the control structure in column 6. The names of all undertakings of the control chain shall be provided in column 2, even if the number of the directly held voting rights and/or financial instruments is not equal or higher than the notifiable threshold. Columns 3 & 4 shall indicate the holdings of those persons or entities directly holding the voting rights and/or financial instruments if the holding is equal or higher than the notifiable threshold.

xr The names of controlled undertakings through which the voting rights and/or financial instruments are effectively held have to be presented irrespectively whether the controlled undertakings cross or reach the lowest applicable threshold themselves
