Attendance at the General Meeting

Only those holders of registered shares entered in the share register as at 5.00 p.m. on July 21, 2015 are entitled to vote at the General Meeting. Individual admission cards will be sent to them two weeks prior to the General Meeting. Admission cards that can no longer be delivered for time reasons will be available for collection at the General Meeting.

No further registrations of voting rights will be carried out in the period from July 22 to July 24, 2015. Registered shareholders who were registered with voting rights as at July 22, 2015, but who sold their shares prior to the General Meeting, must surrender their shareholder rights in respect of the shares sold. At the entrance, they will receive a new admission card corresponding to their current holding of shares.

Holders of bearer shares wishing to attend, or have themselves represented at, the General Meeting may obtain their admission card from their custodian bank between July 1 and July 21, 2015 at the latest. Holders of bearer shares who have not deposited their shares with a custodian bank will receive their admission card directly at the General Meeting upon presentation of their shares or share certificates.

The custodian banks will obtain the admission cards through SIX SAG AG, Sika AG, P.O. Box, 4601 Olten, phone +41 58 399 62 00, fax +41 58 499 61 95, e-mail: generalversammlung@sag.ch by submitting a blocking confirmation and will then send the admission cards to the shareholders. The custodian banks will block the shares in question until after the close of the General Meeting. The custodian banks are requested to provide SIX SAG AG with a full address for service and the name of a contact person for the delivery of the admission cards.
