As an alternative to the redemption of the Convertible Bonds, each bondholder could exercise its conversion rights, following which UCB SA/NV could, in its own discretion, decide to transfer existing UCB shares and/or issue new UCB shares.

Pursuant to the notices received by UCB NV/SA, a number of bondholders have exercised their conversion rights with respect to an aggregate number of 9,985 Convertible Bonds, resulting in:

a) two capital increases for an aggregate amount of € 33,235,518 in capital and € 396,012,275 in issuance premium, and the resulting issuance of an aggregate number of 11,078,506 new UCB shares:

b) the delivery of 1,806,638 existing UCB shares to UCB SA/NV’s wholly owned subsidiary UCB Lux S.A. following the conversion of 1,400 Convertible Bonds (see below).

The remaining 15 Convertible Bonds, with an aggregate nominal value of € 750,000, were not converted but redeemed on March 12, 2014 at par together with interest accrued to that date.
