Elan Corporation, plc (NYSE: ELN) (Elan or the Company) today advises Elan Shareholders to withdraw any acceptances of Royalty Pharma’s Offer without delay and not to tender any further acceptances. Following the outcome of the Elan EGM yesterday morning, and in accordance with the terms of the Royalty Pharma Offer, the Royalty Pharma Offer has now lapsed*. Withdrawal of acceptances of the Royalty Pharma Offer will ensure that Elan Shareholders are in a position to participate in the benefits of the formal sale process which has now commenced. Elan's financial advisers contacted Royalty Pharma's financial advisers over the weekend of 15/16 June for the purpose of inviting Royalty Pharma to participate in that process. The procedures for withdrawal of acceptances are set out in paragraph 4(g) on the Royalty Pharma offer document dated June 10, 2013. *Royalty Pharma had sought the approval from the Irish Takeover Panel to allow it to amend its offer so it would not lapse should the Share Repurchase Program or the ELND005 Transaction be approved by shareholders at the EGM. On June 6, 2013, the Irish Takeover Panel refused to grant such approval. Royalty Pharma has launched judicial review proceedings in the Irish High Court against the decision of the Irish Takeover Panel. Pending the resolution of the proceedings (which are due to be heard on Wednesday 19 June 2013) Royalty Pharma has secured injunctive relief preventing the Irish Takeover Panel - in the event that one or both of the ELND005 Transaction or Share Repurchase Program resolutions are passed but both the Theravance Transaction and the AOP Transaction are rejected - from issuing a direction that Royalty Pharma lapse its offer or from treating the offer as having lapsed for any purposes under the Irish Takeover Panel Act, or otherwise from treating or deeming the offer to have lapsed.
