ROYALTY PHARMA STATEMENT REGARDING ELAN LAW SUITS

Royalty Pharma Deplores What it Believes are Efforts by Elan to Deprive Shareholders of an

Opportunity to Consider Royalty Pharma Offer

Elan Withdraws Law Suit in Ireland After Court Confirms Jurisdiction of Irish Takeover Panel

Elan Law Suit in the United States is Entirely Without Merit, Royalty Pharma Says

New York - June5,2013 - Royalty Pharma announced today that on Tuesday, June 4, 2013, Elan withdrew a lawsuit it had filed on an emergency basis only the previous day. Elan’s suit, filed on Monday, June 3, 2013, a public holiday in Ireland, without giving Royalty Pharma notice or an opportunity to respond, sought an emergency order from the Irish High Court on the basis that Elan had been unable to contact the Panel, this despite the fact that Royalty Pharma itself had been in regular communication with the Panel over the holiday weekend who had helpfully made itself available as it has on a number of occasions on this matter. On the basis of these statements by Elan, the court granted Elan relief for one day in order to give Royalty Pharma an opportunity to respond. When it became apparent in the High Court at the hearing on Tuesday, June 4, 2013, that claims brought by Elan were either already being considered by the Panel or were matters that should first be brought to the Panel, Elan withdrew its entire suit as the Panel was clearly the appropriate body to consider the matter.

Elan filed another suit on Monday, June 3, 2013, against Royalty Pharma in the U.S. District Court for the Southern District of New York challenging Royalty Pharma’s offer for Elan shares. The complaint alleges, among other things, that the offer is unfair and financially inadequate, that Royalty Pharma’s tender offer documents contain material misstatements and omissions, and seeks declaratory and injunctive relief to prevent or delay Royalty Pharma from proceeding with the tender offer. Following oral argument, the court set a hearing date of June 11, 2013 to consider Elan’s request for a preliminary injunction and is expected to rule on the matter prior to the June 17 EGM. The court also entered an order ordering expedited discovery and prohibiting Royalty Pharma from “consummating or closing” the Increased Offer prior to the resolution of the matter. Royalty Pharma believes that the action is entirely without merit and it intends to oppose it vigorously.

The actions above demonstrate the lengths the Elan Board of Directors and management are willing to go, in what Royalty Pharma believes is an effort to deny Elan shareholders an opportunity to even consider Royalty Pharma’s offer. Royalty Pharma believes that the Elan Board’s behavior in filing these lawsuits is deplorable.

Forward-looking Statements

This announcement may include certain “forward looking statements” with respect to the business, strategy and plans of Royalty Pharma and its expectations relating to the Increased Offer and Elan’s future financial condition and performance. Statements that are not historical facts, including statements about Elan or Royalty Pharma or Royalty Pharma’s belief and expectation, are forward looking statements. Words such as “believes”, “anticipates”, “estimates”, “expects”, “intends”, “aims”, “potential”, “will”, “would”, “could”, “considered”, “likely”, and variations of these words and similar future or conditional expressions are intended to identify forward looking statements but are not the exclusive means of identifying such statements. By their nature, forward looking statements involve risk and uncertainty because they relate to events and depend upon future circumstances that may or may not occur.

Examples of such forward looking statements include (but are not limited to) statements about expected benefits and risks associated with the Increased Offer; projections  or   expectations  of   profit  attributable  to   shareholders;  anticipated provisions or write-downs, economic profit, dividends, capital structure or any other

financial items or ratios; statements of plans, objectives or goals of Elan, the Elan Group, RP Management or Royalty Pharma following the Increased Offer; statements about the future trends in interest rates, liquidity, foreign exchange rates, stock market levels and demographic trends and any impact that those matters may have on Elan, the Elan Group, RP Management or Royalty Pharma following the Increased Offer; statements concerning any future Irish, US or other economic environment or performance; statements about strategic goals, competition, regulation, regulatory approvals, dispositions and consolidation or technological or regulatory developments; and statements of assumptions underlying such statements.

Forward looking statements only speak as of the date on which they are made, and the events discussed in this announcement may not occur. Subject to compliance with applicable law and regulation, Royalty Pharma is not under any obligation to update publicly or revise forward looking statements, whether as a result of new information, future events or otherwise.

Rule 8 - Dealing Disclosure Requirements

Under the provisions of Rule 8.3 of the Irish Takeover Rules, if any person is, or becomes, “interested” (directly or indirectly) in 1% or more of any class of “relevant securities” of Elan, all “dealings” in any “relevant securities” of Elan (including by means of an option in respect of, or a derivative referenced to, any such “relevant securities”) must be publicly disclosed by not later than 3.30 pm (Irish time) on the “business day” following the date of the relevant transaction. This requirement will continue until the date on which the Increased Offer becomes or is declared unconditional as to acceptances or lapses or is otherwise withdrawn or on which the Offer Period otherwise ends. If two or more persons co-operate on the basis of any agreement, either express or tacit, either oral or written, to acquire an “interest” in “relevant securities” of Elan, they will be deemed to be a single person for the purpose of Rule 8.3 of the Irish Takeover Rules.

Under  the  provisions  of  Rule  8.1  of  the  Irish  Takeover  Rules,  all  “dealings”  in “relevant securities” of Elan by Elan or Royalty Pharma, or by any of their respective “associates” must also be disclosed by no later than 12 noon (Irish time) on the “business day” following the date of the relevant transaction.

A disclosure table, giving details of the companies in whose “relevant securities” “dealings” should be disclosed can be found on the Irish Takeover Panel’s website at www.irishtakeoverpanel.ie.

“Interests in securities” arise, in summary, when a person has long economic exposure, whether conditional or absolute, to changes in the price of securities. In

6

particular, a person will be treated as having an “interest” by virtue of the ownership or control of securities, or by virtue of any option in respect of, or derivative referenced to, securities.

Terms in quotation marks are defined in the Irish Takeover Rules, which can be found on the Irish Takeover Panel’s website.

If you are in any doubt as to whether or not you are required to disclose a “dealing” under Rule 8, please consult the Irish Takeover Panel’s website at www.irishtakeoverpanel.ie or contact the Irish Takeover Panel on telephone number
