Exhibit a(5)(A) FOR immediate RELEASE Investors: Media: Emer Reynolds Anita Kawatra Ph: 353-1-709-4000 Ph: 212-407-5755 800-252-3526 800-252-3526 ELAN announces commencement of tender period for lyons(TM) due 2018 Dublin, Ireland, november 14, 2003-- Elan Corporation, plc (NYSE: ELN) today announced that holders of Liquid Yield Option(TM) Notes due 2018 (Zero Coupon--Subordinated) (the "LYONs") issued by its wholly-owned subsidiary, Elan Finance Corporation Ltd., have the right to surrender their LYONs for purchase during the period that begins today and ends on Monday, December 15, 2003. Pursuant to the indenture under which the LYONs were issued in December 1998, each holder of LYONs has the right to require Elan to purchase, until 5:00 p.m., New York time, on Monday, December 15, 2003, such holder's LYONs at a price equal to $616.57 per $1,000 principal amount at maturity of the LYONs. Under the terms of the LYONs, Elan had the option to pay for the LYONs in cash, in American Depositary Shares ("ADSs"), representing Ordinary Shares, of Elan, or in any combination of cash and ADSs. Elan has elected to pay for the LYONs in cash. The aggregate principal amount due at maturity for all outstanding LYONs is approximately $801.2 million. If all outstanding LYONs were surrendered for purchase, the aggregate cash purchase price would be approximately $494 million. Elan intends to use a portion of the net proceeds from its recently completed offerings of Ordinary Shares and 6.5% Guaranteed Convertible Notes due 2008 to repurchase the LYONs. In order to surrender LYONs for purchase, holders must deliver a purchase notice to The Bank of New York, the trustee and paying agent for the LYONs, on or before 5:00 p.m., New York time, on Monday, December 15, 2003. Holders may withdraw any LYONs previously surrendered for purchase at any time prior to 5:00 p.m., New York time, on Monday, December 15, 2003. Elan Announces Commencement of Tender Period for LYONs(TM) due 2018 Page 2 Elan filed a Tender Offer Statement on Form TO with the Securities and Exchange Commission today. Elan will make available to LYONs holders, through The Depository Trust Company, documents specifying the terms, conditions and procedures for surrendering for purchase and withdrawing LYONs. LYONs holders are encouraged to read these documents carefully before making any decision with respect to the surrender of LYONs, because these documents contain important information regarding the details of Elan's obligation to purchase LYONs. The LYONs are exchangeable into 13.75 Elan ADSs per $1,000 principal amount at maturity of LYONs, subject to certain conditions set forth in the indenture and in the LYONs, and subject to adjustment under certain circumstances. This press release does not constitute an offer to purchase LYONs. The offer to purchase is made solely by Elan's notice dated November 14, 2003. About Elan Elan is focused on the discovery, development, manufacturing, selling and marketing of novel therapeutic products in neurology, pain management and autoimmune diseases. Elan shares trade on the New York, London and Irish Stock Exchanges.

The Ordinary Shares, the Guaranteed Convertible Notes, the guarantee of the Guaranteed Convertible Notes and the shares to be issued upon conversion of the Guaranteed Convertible Notes have not been and will not be registered under the Securities Act and, unless so registered, may not be offered, sold or distributed within the United States or to U.S. persons (as defined in Regulation S under the Securities Act) except pursuant to an exemption from, or in a transaction not subject to, the registration requirements of the Securities Act.
