                             INTRODUCTORY STATEMENT


     This Amendment No. 1 amends and supplements the Tender Offer Statement on
Schedule TO-I ("Schedule TO-I"), originally filed by Elan Corporation, plc, a
public limited company organized under the laws of Ireland (the "Guarantor"),
and Elan Finance Corporation Ltd., a company organized under the laws of Bermuda
and a wholly-owned subsidiary of the Guarantor (the "Company"), on November 14,
2003, which relates to the offer by the Company to purchase, at the option of
the holder (the "Put Option"), the Liquid Yield Option(TM) Notes due 2018 (Zero
Coupon-Subordinated) issued by the Company on December 14, 1998 and fully and
unconditionally guaranteed by the Guarantor (the "Securities"), upon the terms
and subject to the conditions set forth in the Indenture (as defined below), the
Company Notice dated November 14, 2003 (the "Company Notice"), the Securities
and the related offer materials filed as Exhibits (a)(1) to (d)(1) to this
Schedule TO-I (which Company Notice and related offer materials, as amended or
supplemented from time to time, collectively constitute the "Option Materials").
The Securities were issued pursuant to an Indenture, dated as of December 14,
1998 (the "Indenture"), among the Company, the Guarantor and The Bank of New
York, as trustee ("Trustee").

     The Put Option will expire at 5:00 p.m., New York City time, on Monday,
December 15, 2003. This Schedule TO-I, as amended, is intended to satisfy the
disclosure requirements of Rule 13e-4(c)(2) under the Securities Exchange Act of
1934, as amended (the "Exchange Act").

     The terms "Liquid Yield Option" and "LYONs" are trademarks of Merrill Lynch
& Co., Inc.

Item 1.  Summary Term Sheet.

     Item 1 of the Schedule TO-I is hereby amended and supplemented as follows:

     The paragraph appearing under question 7 "When does the Put Option expire?"
in the "Summary Term Sheet" section on page 2 of the Company Notice is hereby
amended and restated in its entirety as follows:

          "The Put Option expires at 5:00 p.m., New York City time, on Monday,
     December 15, 2003 (the "Purchase Date"). Unless otherwise required by
     applicable law, we will not extend the period Holders have to accept the
     Put Option. In addition, we will not change the terms of the Put Option. We
     will pay for purchased Securities promptly following the expiration of the
     Put Option. The Paying Agent must receive your validly surrendered
     Securities before we will pay for your Securities. (Page 4)"

     The paragraph appearing under question 8 "What are the conditions to the
purchase by the Company of the Securities?" in the "Summary Term Sheet" section
on page 2 of the Company Notice is hereby amended and restated in its entirety
as follows:

         "The purchase by the Company of the Securities as to which a Purchase
         Notice has been delivered and not validly withdrawn is conditioned upon
         the Holder delivering the Securities, together with necessary
         endorsements, to the Paying Agent at the same time, or at any time
         after, delivery of the Purchase Notice. Additionally, pursuant to the
         terms of the Indenture, the purchase by the Company of the Securities
         pursuant to the Put Option is conditioned upon there being no Event of
         Default under the Indenture that has occurred (prior to, on or after
         the delivery of a Purchase Notice) and is continuing (other than a
         default in the payment of the Purchase Price with respect to the
         Securities) and upon the purchase being lawful. These conditions are
         required pursuant to the terms of the Indenture and, accordingly, may
         not be waived by the Company or the Guarantor. (page 7)"

     The paragraph appearing under question 10 "If I surrender, when will I
receive payment for my Securities?" in the "Summary Term Sheet" section on page
2 of the Company Notice is hereby amended and restated in its entirety as
follows:

          "We will accept for payment all validly surrendered Securities
     promptly upon expiration of the Put Option, and we will pay for all validly
     surrendered Securities promptly following the expiration of the


                                      -3-


     Put Option. Pursuant to the terms of the Indenture, we will promptly
     forward to the Paying Agent on December 16, 2003 the appropriate amount of
     funds required to pay the Purchase Price for the surrendered Securities.
     The Paying Agent will then promptly distribute the funds to the Holders.
     Holders must deliver their Securities to the Paying Agent before the Paying
     Agent will distribute their funds. (Page 8)"

     The paragraph appearing under question 11 "Until what time can I withdraw
previously surrendered Securities?" in the "Summary Term Sheet" section on page
3 of the Company Notice is hereby amended and restated in its entirety as
follows:

          "You can withdraw Securities previously surrendered for purchase at
     any time until 5:00 p.m., New York City time, on December 15, 2003. You may
     also withdraw previously surrendered Securities at any time after 12:01
     a.m., New York City time, on January 15, 2004, the expiration of 40
     business days from the date of this Company Notice, if your Securities have
     not yet been accepted for payment by the Company. (Page 8)"

Item 4.  Terms of the Transaction.

     Item 4 of the Schedule TO-I is hereby amended and supplemented as follows:

     The seventh paragraph on the cover page of the Company Notice is hereby
amended and restated in its entirety as follows:

          "The Purchase Price for any Security as to which a Purchase Notice has
     been given and not withdrawn will be paid promptly following the expiration
     of the Put Option. The Paying Agent must receive your validly surrendered
     Securities before the Purchase Price for your Securities will be paid."

     The second paragraph of subsection 2.1 "The Company's Obligation to
Purchase the Securities; Purpose of the Transaction" on page 4 of the Company
Notice is hereby amended and restated in its entirety as follows:

          "This Put Option will expire at 5:00 p.m., New York City time, on
     Monday, December 15, 2003 (the "Purchase Date"), and the purchase will be
     made promptly following the expiration of the Put Option. Unless otherwise
     required by applicable law, we will not extend the period Holders have to
     accept the Put Option. In addition, we will not change the terms of the Put
     Option. Pursuant to the terms of the Indenture, the Company will deliver
     funds to the Paying Agent on December 16, 2003 (the "Payment Date"). The
     payment by the Company for validly surrendered Securities is subject to the
     Paying Agent's receipt of the certificate(s) representing the surrendered
     Securities."

     The second sentence of the third paragraph of subsection 2.2 "Purchase
Price" on page 5 of the Company Notice is hereby amended and restated in its
entirety as follows:

         "Each Holder must make his or her own decision whether to surrender his
         or her Securities for purchase and, if so, the principal amount of
         Securities so surrendered based on such Holder's assessment of the
         other information presented in this Company Notice and the current
         market value of the Securities and the ADSs."

     Subsection 2.4 "Market for the Securities and ADSs" on page 5 of the
Company Notice is hereby amended by adding the following paragraph immediately
after the first paragraph of such subsection:

          "To the knowledge of the Guarantor and the Company, the trading
     volumes for the Securities are generally low. To the extent that Securities
     are tendered and accepted pursuant to the Put Option, the trading market
     for the Securities may become even more limited. A bid for a debt security
     with a smaller outstanding principal amount available for trading (a
     smaller "float") may be lower than a bid for a comparable debt security
     with a greater float. Therefore, the market price for Securities not
     tendered may be adversely affected to the extent that the number of
     Securities purchased pursuant to the Put Option reduces the float. The
     reduced float may also tend to make the trading price more volatile.
     Holders of unpurchased


                                      -4-


     Securities may attempt to obtain quotations for the Securities from their
     brokers; however, there can be no assurance that an active trading market
     will exist for the Securities following the consummation of the Put Option.
     The extent of the public market for the Securities following consummation
     of the Put Option would depend on the number of Holders remaining at such
     time and the interest in maintaining a market in the Securities on the part
     of securities firms and other factors."

     Subsection 2.7 "Ranking" on page 6 of the Company Notice is hereby amended
by adding the following paragraph immediately after the first paragraph of such
subsection:

          "As of November 30, 2003, the Company had no senior debt outstanding
     and the Guarantor had approximately $1.272 billion in senior debt
     outstanding. In addition, as of October 31, 2003, the Guarantor's
     subsidiaries (other than the Company) had approximately $1.844 billion of
     liabilities, including trade payables, to which the Guarantor's guarantee
     would have been effectively subordinated. The Indenture does not limit the
     amount of additional senior debt that may be incurred in the future by the
     Guarantor or any of its Subsidiaries (including the Company). However, due
     to restrictions contained in the agreements governing the 9.56 % Guaranteed
     Notes due June 28, 2004 issued by Elan Pharmaceutical Investments II, Ltd.,
     a wholly owned subsidiary of the Guarantor, and guaranteed by the
     Guarantor, and the Series B and Series C Guaranteed Notes due March 15,
     2005 issued by Elan Pharmaceutical Investments III, Ltd., a wholly-owned
     subsidiary of the Guarantor, and guaranteed by the Guarantor, the Guarantor
     and its subsidiaries currently have no ability to incur additional
     indebtedness."

     Subsection 2.8 "Conditions" on page 7 of the Company Notice is hereby
amended and restated in its entirety as follows:

         "The purchase by the Company of the Securities as to which a Purchase
         Notice has been delivered and not validly withdrawn is conditioned upon
         the Holder delivering the Securities, together with necessary
         endorsements, to the Paying Agent at the same time, or at any time
         after, delivery of the Purchase Notice. Additionally, pursuant to the
         terms of the Indenture, the purchase by the Company of the Securities
         pursuant to the Put Option is conditioned upon there being no Event of
         Default under the Indenture that has occurred (prior to, on or after
         the delivery of a Purchase Notice) and is continuing (other than a
         default in the payment of the Purchase Price with respect to the
         Securities) and upon the purchase being lawful. These conditions are
         required pursuant to the terms of the Indenture and, accordingly, may
         not be waived by the Company or the Guarantor.

     Under the Indenture, an Event of Default occurs if:

     -    the Company or the Guarantor default in the making of any payment
          under the Indenture when the payment becomes due and payable, whether
          or not the payment is prohibited by the terms of the Indenture;

     -    the Guarantor fails to deliver ADSs (or cash in lieu of fractional
          ADSs) or cash in lieu thereof when ADSs (or cash in lieu of fractional
          ADSs) or cash in lieu thereof are required to be delivered upon
          exchange of a Security and the failure continues for 10 days;

     -    the Company or the Guarantor fails to comply with any of its other
          agreements in the Securities or the Indenture and the failure
          continues for 60 days after receipt by the Company or the Guarantor,
          as the case may be, of a notice of default;

     -    any default occurs under any bond, debenture, note or other evidence
          or indebtedness for money borrowed of the Company, the Guarantor or
          any of the Guarantor's other subsidiaries, which default shall have
          resulted in indebtedness being accelerated, where the aggregate amount
          so accelerated exceeds the greater of (i) $20 million and (ii) 2.0% of
          the Guarantor's consolidated net assets (calculated in accordance with
          the Indenture) without the indebtedness being discharged or the
          acceleration having been rescinded or annulled within 10 days after
          receipt by the Company or the Guarantor, as the case may be, of a
          notice or default;

     -    certain events of bankruptcy occur with respect to the Company or the
          Guarantor; or


                                      -5-


     -    the Guarantor's guarantee ceases to be in full force and effect or is
          declared null and void or the Guarantor denies that it has any further
          liability under its guarantee or gives notice to such effect.

     There is currently no Default or Event of Default under the Indenture."

     The second sentence of the first paragraph of Section 3 "Procedures to Be
Followed by Holders Electing to Surrender Securities for Purchase" on page 7 of
the Company Notice is hereby amended and restated in its entirety as follows:

     "Additionally, Holders will not be eligible to receive the Purchase Price
     until such time as any certificates representing the surrendered Securities
     are delivered to the Paying Agent."

     The second sentence of the first paragraph of Section 4 "Right of
Withdrawal" on page 8 of the Company Notice is hereby amended and restated in
its entirety as follows:

     "Holders may also withdraw surrendered Securities at any time after 12:01
     a.m., New York City time, on January 15, 2004, the expiration of 40
     business days from the date of this Company Notice, if their Securities
     have not yet been accepted for payment."

     The first paragraph of Section 5 "Payment for Surrendered Securities" on
page 8 of the Company Notice is hereby amended and restated in its entirety as
follows:

          "We will pay for validly surrendered Securities promptly following the
     expiration of the Put Option. We will forward to the Paying Agent, no later
     than 1:00 p.m., New York City time, on December 16, 2003 (the "Payment
     Date") the appropriate amount of funds required to pay the Purchase Price
     for the surrendered Securities. The Paying Agent will then promptly
     distribute the cash to each Holder who validly surrendered Securities. A
     Holder must deliver the Holder's Securities to the Paying Agent before the
     Paying Agent will distribute the Purchase Price to the Holder."

     The second sentence of the first paragraph of Section 10 "Material United
States Tax Considerations" on page 10 of the Company Notice is hereby amended
and restated in its entirety as follows:

     January 15, 2004 (the expiration of 40 business days from the date of the
     Company Notice)."

     Subsection (d) of the third paragraph on page 3 of the Purchase Notice is
hereby amended and restated in its entirety as follows:

     "(d) the undersigned agrees to all of the terms of the Company Notice and
this Purchase Notice."

     The Company will disregard any attestation from holders of the Securities
pursuant to the previous subsection (d) that the holders have "read" the terms
of the Company Notice and the Purchase Notice, to the extent that the Company
receives any executed Purchase Notices from the holders in connection with the
Put Option.

     The third sentence in Section 10 "Withdrawal Right" on page 13 of the
Purchase Notice is hereby amended and restated in its entirety as follows:


                                      -6-
