Major Shareholding Notification • May 18, 2015

IMPORTANT Please read the following instructions before you fill in the declaration

For notifications of large participating interests, the FSMA recommends the use of form TR-1 BE, which it has developed, taking as a basis the European standard form and adapting it to the Belgian regulation.

The form is interactive. Therefore it is essential that you download it again for each new notification. When you select the name of an issuer in the list referred to in point 2, an identification number will automatically appear.

The form consists of two parts: Part I, that must be transmitted to both the FSMA and the issuer, and Part II, to be sent exclusively to the FSMA.

Once you have opened the form on the FSMA's website, start by saving it on your computer (using "save as") before filling it in.

Once vou have saved the form, remember also to verify that macros are active.

The completed form should be sent to trp.fin@fsma.be exclusively as an .xlsm file; otherwise its subsequent processing is impossible.

The names of the persons subject to a notification requirement as indicated in Part I automatically appear in Part II when you click on the "Click here" button in Section 6. Thus it is not possible to add any additional rows in Part II.

In order to add rows in the various sections of Part I (e.g. if there are several notifiers), please use only the "+" and "-" buttons.

Please do not unprotect the form; please fill in only where authorized and do not modify the formulas.

In Section 10, start with groups. In the case of groups of notifiers with sub-totals to be filled in, please identify the members of the group and subsequently click on "8" to fill in a sub-total. Repeat this for each group. Finish with people notifying alone.

Once Section 10 is completed, click on "calculate" to show the totals and sub-totals.

For further details, please refer to the extract from the Guide to the Transparency Legislation.

The (unsigned) form should be transmitted in xls format, and its file name should start with TR-1BE. In addition, a signed copy should also be transmitted, either in PDF format or by fax to +32(2)220.59.12.
