Perrigo and New Perrigo Cautionary Statement Regarding Forward-Looking Statements

This announcement includes certain ‘forward looking statements’ within the meaning of, and subject to the safe harbor created by, Section 21E of the Securities Exchange Act of 1934, as amended, with respect to the business, strategy and plans of each of Perrigo and New Perrigo, their respective expectations relating to the transactions contemplated by the Transaction Agreement and their respective future financial condition and performance, including estimated synergies. Statements that are not historical facts, including statements about Perrigo’s, New Perrigo’s or their respective managements’ beliefs and expectations, are forward looking statements. Words such as ‘believes’, ‘anticipates’, ‘estimates’, ‘expects’, ‘intends’, ‘aims’, ‘potential’, ‘will’, ‘would’, ‘could’, ‘considered’, ‘likely’, ‘estimate’ 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.

Examples of such forward looking statements include, but are not limited to, statements about expected benefits and risks associated with the transactions contemplated by the Transaction Agreement, projections or expectations of profit attributable to shareholders, including estimated synergies, anticipated provisions or write-downs, economic profit, dividends, capital structure or any other financial items or ratios; statements of plans, objectives or goals of Perrigo, New Perrigo, Elan or the combined business following the transactions contemplated by the Transaction Agreement; statements about the future trends in tax or interest rates, liquidity, foreign exchange rates, stock market levels and demographic trends and any impact that those matters may have on Perrigo, New Perrigo, Elan or the combined company following the transactions contemplated by the Transaction Agreement; statements concerning any future Irish, UK, US or other economic or regulatory environment or performance; statements about strategic goals, competition, regulation, regulatory approvals, dispositions and consolidation or technological developments in the healthcare and life sciences industry; and statements of assumptions underlying such statements.

While Perrigo and New Perrigo believe these expectations, assumptions, estimates and projections are reasonable, such forward-looking statements are only predictions and involve known and unknown risks and uncertainties, many of which are beyond Perrigo’s and New Perrigo’s control. 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. Actual results may differ materially from Perrigo’s and New Perrigo’s current expectations depending upon a number of factors affecting Perrigo’s business, New Perrigo’s business, Elan’s business and risks associated with acquisition transactions. These factors include, among others, the inherent uncertainty associated with financial projections; restructuring in connection with, and successful close of, the transactions contemplated by the Transaction Agreement; subsequent integration of the transactions contemplated by the Transaction Agreement and the ability to recognize the anticipated synergies and benefits of the transactions contemplated by the Transaction Agreement; the receipt of required regulatory approvals for the transactions contemplated by the Transaction Agreement (including the approval of antitrust authorities necessary to complete the transactions contemplated by the Transaction Agreement); access to available financing (including financing for the transactions contemplated by the Transaction Agreement) on a timely basis and on reasonable terms; the risks and uncertainties normally incident to the pharmaceutical industry, including product liability claims and the availability of product liability insurance; market acceptance of and continued demand for Perrigo’s, New Perrigo’s and Elan’s products; changes in tax laws or interpretations that could increase Perrigo’s or the combined company’s consolidated tax liabilities; and such other risks and uncertainties detailed in Perrigo’s periodic public filings with the SEC, including but not limited to those discussed under “Risk Factors” in Perrigo’s Form 10-K for the fiscal year ended 30 June 2012, in Perrigo’s subsequent filings with the SEC and in other investor communications of Perrigo or New Perrigo from time to time.

The forward-looking statements in this announcement are made only as of the date hereof, and unless otherwise required by applicable securities laws, each of Perrigo and New Perrigo disclaims any intention or obligation to update or revise any forward-looking statements, whether as a result of new information, future events or otherwise.

A further list and description of these risks, uncertainties and other matters can be found in Elan’s Annual Report on Form 20-F for the fiscal year ended 31 December 2012, and in its Reports of Foreign Issuer on Form 6-K filed with the SEC. Elan assumes no obligation to update any forward-looking statements, whether as a result of new information, future events or otherwise.

Dealing Disclosure Requirements

Under the provisions of Rule 8.3 of the Irish Takeover Panel Act, 1997, Takeover Rules 2007, as amended (the “Takeover Rules”), if any person is, or becomes, “interested” (directly or indirectly) in 1% or more of any class of “relevant securities” of Elan or Perrigo, all “dealings” in any “relevant securities” of Elan or Perrigo (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 Scheme becomes effective 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 or Perrigo, they will be deemed to be a single person for the purpose of Rule 8.3 of the Takeover Rules.

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 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 Takeover Rules, which can be found on the Irish Takeover Panel’s website.
