                Elan ANNOUNCES AGREEMENT WITH VERNALIS REGARDING
                      NORTH AMERICAN RIGHTS FOR FROVA(TM)

Dublin, Ireland, March 30, 2004--Elan Corporation, plc today announced an
agreement with Vernalis plc for the termination of the development and license
agreements between Elan and Vernalis regarding Frova (frovatriptan). Vernalis
agreed to purchase Elan's commercialisation rights in North America for Frova.

Kelly Martin, Elan's president and chief executive officer, said, "This
transaction allows Elan to further align against our strategic architecture in
research, development and marketing. We will focus our resources on preparing
for the expected launch of our late-stage pipeline candidates, Antegren for
multiple sclerosis and Crohn's disease, and Prialt for pain."

Under the terms of the agreement, Vernalis will pay Elan a total of
approximately $55 million for rights to frovatriptan in North America,
comprising the following payments. Upon closing, Elan will receive $5 million;
on December 31, 2004 and December 31, 2005, Elan will receive payments of $20
million and $25 million respectively; and no later than December 31, 2004, Elan
will receive a payment for its Frova inventory, estimated at approximately $5
million. Additionally, Elan's co-promotion agreement with UCB Pharma, Inc. will
be terminated at closing, and Elan will pay UCB about $10 million as a result of
the termination.

For the full-year 2003, Elan recorded net revenue and gross profit for Frova of
$37.5 million and $8.1 million, respectively. The carrying value of the Frova
intangible asset is approximately $23 million.




The sale proceeds will be used for development and launch of late-stage pipeline
candidates. The completion of the transaction is subject to the approval of
Vernalis' shareholders, U.S. anti-trust clearance if required, third party
consents and other customary conditions. The transaction is expected to close
before the end of the second quarter of 2004.

                      ELAN ANNOUNCES STRATEGIC TRANSACTION
 Eisai to Purchase Elan's Interests in Zonegran(TM) in North America and Europe

Dublin, Ireland, March 30, 2004--Elan Corporation, plc today announced an
agreement with Eisai Co., Ltd. for the purchase of Elan's interests in Zonegran
(zonisamide) in North America and Europe.

Elan President and CEO Kelly Martin said, "This transaction further aligns
Elan's strategy in research, development, sales and marketing with our
therapeutic areas. In research, it sharpens our focus in neurology, in which we
continue research and advances in neurodegenerative diseases, including multiple
sclerosis, Alzheimer's disease, and Parkinson's disease. In development, sales,
and marketing, it enables us to focus our resources on the expected launch of
our late-stage pipeline candidates, Antegren for multiple sclerosis and Crohn's
disease, and Prialt for severe pain. In addition, the agreement creates an
opportunity for Eisai to leverage the potential for Zonegran."

Terms of Transaction
Under the terms of the agreement, if the transaction closes by April 30, 2004,
Eisai will pay Elan total consideration of approximately $130 million for Elan's
interests in Zonegran in North America and Europe. Elan's interests comprise
U.S., Canadian, Mexican, and European rights to Zonegran, along with related
assets and liabilities, Zonegran inventory with an estimated value of $26
million, and the associated sales team of approximately 115 employees.

If the transaction closes after April 30, 2004, the amount paid to Elan will be
adjusted downward. In addition, Elan may earn future deferred purchase payments
of up to $110 million,





primarily contingent on when generic zonisamide is introduced in the U.S., and
including up to $25 million contingent on receiving marketing approval for
Zonegran in Europe. Elan will also receive additional deferred purchase payments
on net sales of Zonegran in North America and Europe if certain additional
conditions are met.

Elan will continue to manufacture Zonegran in all three dosage strengths of 25
mg, 50 mg, and 100 mg capsules in Athlone, Ireland.

Based on a closing by April 30, Elan expects to record a pre-tax gain of
approximately $25 million from this transaction, after writing off the
intangible assets related to Zonegran, a payment of $17 million to Dainippon
Pharmaceutical Co., Ltd. for the assignment of the Zonegran North American and
European license agreements to Eisai and other transaction costs. Additionally,
Elan expects to record further pre-tax gains of up to $110 million on receipt of
future milestone payments. For the full-year 2003, Elan recorded net revenue and
gross profit for Zonegran of $80.7 million and $59.4 million, respectively.

The transaction is subject to regulatory approvals, third party consents and
other customary conditions, and is expected to close before the end of second
quarter 2004. The proceeds of this transaction will be used for development and
potential launch of late-stage pipeline candidates.

EBITDA Guidance
As a result of this transaction and the Vernalis transaction announced earlier
today, negative EBITDA guidance for 2004 will change from the range of negative
$150-170 million to negative $180-200 million, and product revenue guidance for
2004 will decrease from $575-625 million to $475-525 million. This guidance does
not include any additional costs, which may be substantial, that may be incurred
from anticipated early filings and potential launch preparation for Antegren for
multiple sclerosis in the U.S. and Europe.

Administration in March 2000 as adjunctive therapy for the treatment of partial

candidates may never be launched. Elan may not achieve the results forecast in
