CAUTIONARY FACTORS THAT MAY AFFECT FUTURE RESULTS

(Cautionary Statements Under the United States Private Securities Litigation
Reform Act of 1995)

Our disclosure and analysis in this Annual Report and Form 20-F contain some
forward-looking statements that set forth anticipated results based on
management's plans and assumptions. From time to time, we also provide
forward-looking statements in other materials we release to the public as well
as oral forward-looking statements. Such statements give our current
expectations or forecasts of future events; they do not relate strictly to
historical or current facts. We have tried, wherever possible, to identify such
statements by using words such as "anticipate", "estimate", "expect",
"project", "intend", "plan", "believe", "will", "strategy" and similar
expressions in connection with any discussion of future operating or financial
performance. In particular, these include statements relating to future
actions, our ability to meet our future financial obligations, the success of
our recovery plan, prospective products or product approvals, future
performance or results of current and anticipated products, sales efforts,
expenses, interest rates, the outcome of contingencies, such as legal
proceedings and governmental investigations, and financial results.

We cannot guarantee that any forward-looking statements will be realised.
Achievement of future results is subject to risks, uncertainties and
potentially inaccurate assumptions. Should known or unknown risks or
uncertainties materialise, or should underlying assumptions prove inaccurate,
actual results could vary materially from past results and those anticipated,
estimated or projected. Investors should bear this in mind as they consider
forward-looking statements.

We undertake no obligation to publicly update forward-looking statements,
whether as a result of new information, future events or otherwise. You are
advised, however, to consult any further disclosures we make on related
subjects in our 6-K reports submitted to the United States Securities and
Exchange Commission ("SEC"). Also note that we provide the following cautionary
discussion of risks, uncertainties and possibly inaccurate assumptions related
to our business. This discussion, together with the discussion under "Risk
Factors" located elsewhere in this Annual Report and Form 20-F, describe the
factors that, individually or in the aggregate, we think could cause our actual
results to differ materially from expected and historical results. We note
these factors for investors as permitted by the United States Private
Securities Litigation Reform Act of 1995. You should understand that it is not
possible to predict or identify all such factors. Consequently, you should not
consider these factors to be a complete discussion of all potential risks or
uncertainties. These factors include those set forth under the heading "Risk
Factors" located elsewhere in this Annual Report and Form 20-F and the
following:

o  the outcome of our recovery plan and our ability to maintain financial
   flexibility and maintain sufficient cash, liquid resources, and investments
   and other assets capable of being monetised to meet our liquidity
   requirements;
o  the outcome of the ongoing SEC investigation and shareholder litigation,
   including the impact, if any, that the 2001 restatement may have on the
   outcome of the shareholder litigation;
o  the success of research and development activities and the speed with which
   regulatory authorisations and product launches may be achieved;
o  competitive developments affecting our current products;
o  our ability to protect our intellectual property;
o  our ability to successfully market both new and existing products;
o  difficulties or delays in manufacturing;
o  our ability to meet generic and branded competition after the expiration of
   our patents or our regulatory exclusivity;
o  the trend towards managed care and health care cost containment;
o  possible legislation affecting pharmaceutical pricing;
o  exposure to product liability and other types of lawsuits;
o  interest rate and foreign currency exchange rate fluctuations;
o  governmental laws and regulations affecting domestic and foreign operations,
   including tax obligations;
o  general changes in Irish and U.S. GAAP;
o  our ability to reduce costs and expenses;
o  changes in product mix; and
o  the impact of acquisitions, divestitures, restructurings, product withdrawals
   and other unusual items.

Garo H. Armen and G. Kelly Martin


DEAR SHAREHOLDERS:

2002 was an extremely difficult year for all of our constituents, particularly
for our shareholders and employees. In the early months of 2002, we suffered a
number of setbacks in rapid succession, including the cessation of dosing in a
Phase IIA clinical trial of AN-1792, the announcement of a profit warning and
an investigation by the United States Securities and Exchange Commission. These
disappointments ultimately led to a loss of confidence in the Company,
resulting in a change of corporate leadership.

To address these issues, the board of directors of Elan announced my
appointment as Chairman on 9 July 2002, tasking me with the responsibility of
overseeing the rebuilding process. Shortly thereafter, we put into place a new
management team from the ranks of Elan and announced the implementation of the
rebuilding of our Company, which is comprised of the following components:

o  Our recovery plan, to improve liquidity, simplify our structure and reduce
   the cost of conducting our business;
o  Our growth plan, which is designed to bring to fruition our innovative
   products and technologies; and
o  Our operational excellence plan, which is designed to put into place the
   structures and processes needed to build a world-class biopharmaceutical
   company.

Since Elan's recovery plan was announced in July 2002, we have achieved a
substantial number of our key objectives. In the last year, we have made
significant progress towards restoring our financial health, cutting our costs,
and streamlining our balance sheet. By the end of the first quarter of 2003 we
had reduced our commitments by approximately $1.4 billion and had cash reserves
of approximately $1 billion. With the recent completion of the sale of our
primary care business to King Pharmaceuticals, we have exceeded our target of
$1.5 billion in gross asset sales -- six months before our target of the end of
2003. We have also reduced our headcount by approximately 1,900 and formally
restructured 36 joint ventures. We will continue to divest non-core businesses
and assets to further add to our liquidity.

The success of our recovery effort will ultimately be judged by our ability to
develop biopharmaceutical products to treat important diseases, and our ability
to return to profitability. As part of the recovery process, we will continue
to simplify our balance sheet and provide investors with a transparent view of
our finances. In this regard, as previously announced, we have restated our
U.S. GAAP financial results for 2001. In addition, our unaudited U.S. GAAP
financial information for 2002 has been adjusted. This restatement does not
affect our Irish GAAP financial data. We are also continuing discussions with
the enforcement division of the SEC.

It is paramount that all of our constituents -- the public, the capital markets
and the relevant regulatory agencies -- have complete confidence in our ability
to manage our business with the highest ethical standards and our ability to
exercise prudent business judgements.

Our progress in restoring financial stability over the last year has given us a
greater ability to focus on our pipeline, which is critical to restoring value
to the Company and its shareholders. As the recovery plan proceeds, we continue
to invest significant effort in unlocking the value of our pipeline. Elan's

CHAIRMAN'S STATEMENT
- --------------------------------------------------------------------------------

biopharmaceutical product pipeline includes several innovative products in the
fields of neurodegeneration and pain.

Antegren, our humanised monoclonal antibody, has already delivered promising
data in Phase II studies for Crohn's disease and multiple sclerosis; results
from both trials were published in the 2 January 2003 issue of the New England
Journal of Medicine. Phase III studies for these two indications are now fully
enrolled and we just announced the results of the Phase III induction study in
Crohn's disease. While we missed the primary endpoint we are very encouraged by
the overall results. The Antegren Phase III maintenance trial for Crohn's
disease and two Phase III trials for multiple sclerosis are on-going.

Also in development are two new compounds from our Alzheimer's disease
immunotherapy collaboration with Wyeth. These compounds have the potential to
alter the future treatment of this disease. For more than a decade, Elan has
sustained one of the largest and most productive research efforts in
Alzheimer's disease. As a result, our discoveries have evolved into valuable
new compounds of exceptional therapeutic potential. Our product pipeline also
includes advanced therapies such as Prialt for severe chronic pain.

We expect to file several New Drug Applications and European Marketing
Authorisation Applications by the end of 2004. In addition, we expect to file
two Investigational New Drug Applications to start clinical trials in our
Alzheimer's immunotherapy programme within the next 15 months. Taken as a
whole, this pipeline represents the key to Elan's success.

Amid the difficulties of 2002, many of us at Elan were reminded of the true
purpose of our efforts -- to develop treatments for patients suffering from
debilitating diseases. It is the collective spirit of Elan's people that has
enabled us to make the significant progress we have achieved in turning the
Company around in a remarkably short period of time. We have begun transforming
Elan into a focused company with a specialised sales and marketing
organisation, a unique pipeline and a talented group of employees with a strong
commercial execution capability in the market. As we follow through on the
recovery plan, our goal is to position ourselves to maximise the opportunities
of Elan's current businesses while investing in our pipeline and its potential
contribution to future value.

When I accepted the position of Chairman and acting CEO in July 2002, it was
clear that we would quickly start a search for a new CEO. We sought a candidate
who possessed a sense of discipline and a high level of business expertise.
Kelly Martin brings all of that -- plus a passionate belief in what our Company
stands for and what it can accomplish. His judgement, his integrity and his
leadership are ideally suited to guide the new Elan. I am delighted he is
leading our Company and our people, and I will continue to work closely with
him as Chairman. In covering such a great distance in so short a time, we have
begun to re-establish the hope that Elan can become a leader in our industry
and restore value for our stakeholders. We have a considerable number of
strengths in our favour, from the dedication of our employees to the quality of
our pipeline -- all of which we will maximise in order to ensure Elan's success
for the future.

In closing, I would like to thank our shareholders for their support, our board
of directors for their dedication and leadership, and our senior management and
employees for their tireless efforts during the past year.

COMPANY OVERVIEW

Elan, an Irish public limited company, is a worldwide biopharmaceutical company
headquartered in Dublin, Ireland. Elan was incorporated as a private limited
company in Ireland on 18 December 1969 and became a public limited company on 3
January 1984. Elan's principal executive offices are located at Lincoln House,
Lincoln Place, Dublin 2, Ireland and its telephone number is 353-1-709-4000.
Elan's principal research and development, manufacturing and marketing
facilities are located in Ireland, the United States and the United Kingdom.

During 2001 and through mid-2002, Elan conducted its operations through two
primary business units: Biopharmaceuticals and Drug Delivery. On 31 July 2002,
Elan announced a recovery plan to restructure its businesses, assets and
balance sheet in order to enable it to meet its financial commitments. With the
implementation of the recovery plan, Elan will focus on three core therapeutic
areas: neurology, pain management and autoimmune diseases. In accordance with
this new focus, the Group was reorganised and two new units were created: Core
Elan and Elan Enterprises.

Core Elan is engaged in pharmaceutical commercial activities and
biopharmaceutical research and development activities. Core Elan is also
engaged in pharmaceutical manufacturing activities at its facility in Athlone,
Ireland. Elan's pharmaceutical commercial activities include the marketing of
products in the therapeutic areas of neurology, pain management and infectious
diseases. Biopharmaceutical research and development activities include the
discovery and development of products in the therapeutic areas of neurology,
pain management and autoimmune diseases.

Elan's biopharmaceutical product pipeline currently includes several innovative
products in development in the fields of autoimmune diseases and pain
management, including Antegren, which is in Phase III clinical trials for
multiple sclerosis ("MS") and Crohn's disease, in collaboration with Biogen,
Inc. ("Biogen"), and Prialt, which is in Phase III clinical trials for severe
chronic pain. Additionally, Elan remains committed to the advancement of its
broad Alzheimer's disease ("AD") programmes with Wyeth and Pfizer Inc.
("Pfizer") (formerly Pharmacia Corporation ("Pharmacia")) and its internal
discovery programmes.

Elan expects to file three U.S. New Drug Applications ("NDAs") and four
European Marketing Authorisation Applications ("MAAs") by the end of 2004. Elan
also expects two Investigational New Drug Applications ("IND") from its
Alzheimer's collaboration with Wyeth to be filed within the next 15 months.

Elan Enterprises is mainly comprised of Elan's drug delivery businesses and
other assets such as business ventures and non-core pharmaceutical products.
Drug delivery activities have historically included the development, licensing
and marketing of drug delivery products, technologies and services to
pharmaceutical industry clients on a worldwide basis. Elan Enterprises is
seeking to dispose of many of these businesses and assets.

COMPANY MISSION AND GOALS

Elan's mission is to become a fully integrated, world-class company capable of
developing effective and novel treatments in the core areas of neurology, pain
management and autoimmune diseases. Elan is committed to discovering,
developing and marketing new, innovative products that address the world's most
debilitating medical conditions, that improve the health and quality of life
for patients and their families, and that meet the requirements of the
healthcare professionals who treat them. Elan will conduct its business with
the highest standards of ethics

and integrity and believes in serving patients, customers, investors and
employees.

RECOVERY PLAN--DIVESTITURE PROGRAMME

A key element of the recovery plan is the divestiture of businesses, products,
investments and other assets. The objective was to complete $1.5 billion in
asset divestitures by the end of 2003. Since its commencement in August 2002,
the divestiture programme has generated gross consideration in excess of $1.7
billion.

XCEL

On 1 April 2003, Elan announced that it received $89.5 million in cash from
Xcel Pharmaceuticals, Inc. ("Xcel") in exchange for all of Elan's shareholding
in, and loans to, Xcel.

SKELAXIN & SONATA

On 30 January 2003, Elan announced that it had agreed to sell its primary care
franchise, principally consisting of its U.S. and Puerto Rican rights to Sonata
and Skelaxin, related inventory and related rights to enhanced formulations of
these products, to King Pharmaceuticals, Inc ("King").

On 17 March 2003, Elan commenced a lawsuit against King to compel King to
complete its purchase of the primary care franchise. On 19 May 2003, Elan and
King agreed to proceed with the transaction on amended terms and on 12 June
2003 the transaction was completed. Effective upon the closing of the
transaction, all claims under the pending litigation were released and Elan and
King dismissed the litigation with prejudice.

Under the terms of the amended transaction, King paid gross consideration on
closing of $749.8 million, which included the transfer to King of Sonata and
Skelaxin inventory with a value of approximately $40 million and obligations
related to Sonata of $218.8 million that were assumed by King at closing. In
addition, Elan will receive an additional $25.0 million payment on 2 January
2004, contingent on the ongoing patent exclusivity of Skelaxin. Elan will also
receive payments of 5% of net sales of the current formulation of Skelaxin
through 31 December 2005 and, thereafter, beginning in 2006 and continuing
through December 2021, Elan will receive payments of 10% of net sales of the
current formulation of Skelaxin in excess of $50.0 million of net sales
annually. Finally, Elan will receive up to an additional $61.0 million in
milestone payments (comprised of up to $86.0 million in clinical, regulatory
and sales milestones less up to $25.0 million in milestones that Elan is
obligated to pay to a third party) relating to the development of enhanced
formulations of Sonata, contingent on the achievement of certain clinical and
regulatory events. Elan has agreed to indemnify King for certain events.

ATHENA DIAGNOSTICS

On 31 December 2002, Elan, together with the other stockholders in Elan's
subsidiary, Athena Diagnostics, Inc. ("Athena Diagnostics"), sold all of the
outstanding stock of Athena Diagnostics to Behrman Capital and certain of its
affiliated investment funds ("Behrman"). The gross consideration was
approximately $122 million in cash. Prior to the sale, Elan held approximately
80% of Athena Diagnostics' common stock. As a result of the sale, Elan received
$81.8 million in cash, after giving effect to certain contractual payments,
including payments to Athena Diagnostics' other stockholders.

AVINZA / LIGAND COMMON STOCK

On 9 December 2002, Elan announced the amendment of the terms of its
development, licence and supply agreement with Ligand Pharmaceuticals, Inc.
("Ligand") regarding Avinza. Elan received a cash payment of $100.0 million from
Ligand, in return for a reduction in the ongoing royalty rate from the previous
level of 30% of net sales of Avinza in the United States and Canada to
approximately 10%. In addition, Elan agreed to forego its option to negotiate a
co-promotion agreement with Ligand for Avinza in the United States and Canada.
Elan continues to manufacture the product in its Gainesville facility.

Ligand also agreed to repurchase from Elan approximately 2.2 million shares of
Ligand common stock for a cash purchase price of $20.0 million. The share sale
closed in February 2003.

On 28 May 2003, Elan sold 6.4 million shares of Ligand common stock in the open
market for net cash proceeds of $73.0 million. On 11 July 2003, Elan sold its
remaining 5.8 million shares of Ligand common stock to a number of qualifying
institutional investors for net cash proceeds of $65.1 million.

ABELCET

On 22 November 2002, Elan announced the completion of the sale of its U.S.,
Canadian and any Japanese rights to Abelcet and certain related assets to Enzon
Pharmaceuticals, Inc. ("Enzon"). Elan retains its existing rights to market
Abelcet in territories outside of the United States, Canada and Japan. Elan
received a net cash payment of $360.0 million from Enzon. Elan has agreed to
indemnify Enzon for certain events.



Included in the transaction was related intellectual property, Elan's
manufacturing facility in Indianapolis, Indiana and inventory. The Indianapolis
facility manufactures Abelcet and Myocet. Elan and Enzon entered into a
long-term


- --------------------------------------------------------------------------------

- --------------------------------------------------------------------------------

manufacturing and supply agreement whereby Enzon will continue to manufacture
Elan's requirements for these two products.

ACTIQ

On 3 October 2002, Elan announced that it had sold its rights to Actiq in
twelve territories, principally in Europe, to Anesta Corp. ("Anesta"), a
subsidiary of Cephalon, Inc. At the date of disposal, Actiq was marketed by
Elan in the United Kingdom, Ireland and Germany. Elan received $50.0 million in
cash from Anesta.

NIFEDIPINE ER

On 23 August 2002, Elan announced a licensing agreement with Watson
Pharmaceuticals, Inc. ("Watson") for exclusive marketing rights to the 30mg and
60mg dosage strengths of Elan's extended-release nifedipine tablets in the
United States. Elan received $45.0 million in cash from Watson. Elan continues
to manufacture the product in its Athlone, Ireland facility.

For further information on these disposals, including the impact of these
disposals on Elan's financial results, please refer to the Financial Review.

FUTURE TRANSACTIONS

Elan intends to sell further businesses, products, investments and other assets
as part of its recovery plan. Assets from both Core Elan and Elan Enterprises
may be disposed of as part of the recovery plan.

RECOVERY PLAN--FINANCIAL COMMITMENTS AND CONTINGENCIES

A key objective of the recovery plan is to enable Elan to meet its financial
obligations and to simplify its balance sheet.




                                                                             
Contractual and potential future payments have been reduced by
approximately $1.4 billion, from $4.5 billion at 31 December 2001 to $3.1
billion at 31 December 2002, after giving effect to the restructuring of the
risk-sharing arrangement with Pharma Marketing Ltd. (together with its
subsidiary, "Pharma Marketing") in January 2003 as described below. The
main elements of the reduction were:

Repaid 3.5% Convertible Subordinated Notes ("3.5% Convertible Notes")            $ 62.4
- ---------------------------------------------------------------------------------------
Risk-sharing arrangements                                                        $215.0
- ---------------------------------------------------------------------------------------
Repurchased 3.25% Zero Coupon Subordinated Exchangeable Notes ("LYONs")          $196.5
- ---------------------------------------------------------------------------------------
Reduced fixed, contingent and potential product payment obligations              $418.2
- ---------------------------------------------------------------------------------------
Reduced Elan Pharmaceutical Investments III, Ltd. ("EPIL III") debt              $160.0
- ---------------------------------------------------------------------------------------


REVOLVING CREDIT FACILITY AND 3.5% CONVERTIBLE NOTE REPAYMENT

On 11 July 2002, Elan repaid in full and terminated its revolving credit
facility of $325.0 million. On 15 July 2002, Elan repaid at maturity the
remaining $62.4 million in aggregate principal amount of the 3.5% Convertible
Notes. These convertible notes were assumed as part of the acquisition of Dura
Pharmaceuticals, Inc. ("Dura"), in November 2000.

RISK-SHARING ARRANGEMENTS

Potential future payments relating to the risk-sharing arrangements have
decreased by $215.0 million to $335.0 million at 31 December 2002 from $550.0
million at 31 December 2001. This reduction arises from the termination during
2002 of the risk-sharing arrangement with Autoimmune Diseases Research &
Development Corp. Ltd. (together with its subsidiary, "Autoimmune"), and the
restructuring in January 2003 of the risk-sharing arrangement with Pharma
Marketing.

Elan's risk-sharing arrangement with Autoimmune was terminated in the third
quarter of 2002. Elan paid $121.0 million as part of this termination which,
after taking account of the redemption of Elan's investment of $38.5 million in
Autoimmune, resulted in a net cash cost of $82.5 million.



Elan's risk-sharing arrangement with Pharma Marketing was restructured in
January 2003, such that effective upon the sale of Sonata to King on 12 June
2003, (i) Elan paid Pharma Operating Ltd. ("Pharma Operating") $196.4 million
in cash (representing $225.0 million less royalty payments on all related
products paid or due to Pharma Operating from 1 January 2003 through 12 June
2003) to acquire Pharma Operating's royalty rights with respect to Sonata and
Prialt and (ii) Elan's maximum purchase price for the remaining products in the
arrangement, Zonegran, Frova and Zanaflex, was reduced to $110.0 million, which
will increase at a rate of 15% per annum from 12 June 2003 (less royalty
payments made for periods after 12 June 2003). The parties also agreed to
extend Elan's purchase option termination date to 3 January 2005 from the
original termination date of 30 June 2003.

LYONS

In December 1998, Elan Finance Corporation Limited ("Elan Finance"), a wholly
owned subsidiary of Elan, issued in a private placement, at a substantial
discount, LYONs due 2018 in the principal amount of $1,643.5 million at
maturity. The issue price of the LYONs was $524.78 per $1,000 principal amount
at maturity and the gross proceeds to the Company amounted to $862.5 million.

During the fourth quarter of 2002, Elan repurchased $318.6 million in principal
amount at maturity of the LYONs (representing approximately 19% of the
originally issued LYONs) in separate privately negotiated purchases. The
aggregate cost was $149.8 million. This was a discount of approximately 24% to
the accreted value of such LYONs at 14 December 2003 of $196.5 million. After
taking account of this repurchase, the accreted value of the remaining LYONs
was $792.3 million at 31 December 2002.

Through 3 June 2003, Elan repurchased an additional $523.7 million in principal
amount at maturity of the LYONs (representing approximately 32% of the
originally issued LYONs) in separate privately negotiated purchases. The
aggregate cost was $310.3 million. This was a discount of approximately 4% to
the accreted value of such LYONs at 14 December 2003 of $322.9 million. After
taking account of all repurchases up to 3 June 2003, the remaining LYONs have
an accreted value at 14 December 2003 of $494.0 million. Elan may purchase
additional LYONs in the future and any such purchases may be material.

For additional information on the LYONs, please refer to Note 16 to the
Consolidated Financial Statements.

FIXED, CONTINGENT AND POTENTIAL PRODUCT PAYMENT OBLIGATIONS

The net reduction of $418.2 million in fixed, contingent and potential product
payment obligations from 31 December 2001 to 31 December 2002 primarily
reflects product payments made during 2002 of $234.6 million and contingent
product payments avoided of $224.3 million. The contingent product payments
avoided relate primarily to Elan's decision during 2002 not to exercise its
option to acquire certain dermatology products from GlaxoSmithKline, plc
("GSK").

ELAN PHARMACEUTICAL INVESTMENTS II, LTD. ("EPIL II") / EPIL III

In June 2002, EPIL III repaid $160.0 million in aggregate principal amount of
Series A guaranteed senior notes (the "Series A Guaranteed Notes").

For additional information on the 9.56% guaranteed senior notes issued by EPIL
II (the "EPIL II Notes"), and the Series A Guaranteed Notes, the Series B
guaranteed senior notes (the "Series B Guaranteed Notes") and the Series C
guaranteed senior notes (the "Series C Guaranteed Notes") issued by EPIL III
(collectively, the "EPIL III Notes") please refer to Note 3, Note 16 and Note
33 to the Consolidated Financial Statements.

REVIEW OF BUSINESS VENTURES

In 2002, Elan completed a review of its business venture portfolio to conserve
cash and reflect the reduced scope of Elan's activities. As a result, it is
Elan's intention to restructure or terminate substantially all of its business
ventures with the aim of substantially reducing or eliminating future cash
outlays by Elan with respect to those business ventures.

Elan recognised exceptional charges in its profit and loss account for 2002 to
reflect impairments to the Group's investment portfolio, including investments
held by EPIL II and EPIL III. This includes impairment charges relating to
investments in business ventures and business venture parent companies.

WORLD PHARMACEUTICAL MARKET

Audited global pharmaceutical sales increased by 8% from 2001 to $400.6 billion
in 2002.(1) In 2001, audited global pharmaceutical sales increased by 11% over
2000.(1) Sales increased due to strengthening generic drug sales in North
America and Western Europe and the ageing of the global population, among other
factors.

North America, Japan and Western Europe accounted for approximately 85%(1) of
global pharmaceutical sales in 2002. North America's pharmaceutical sales grew
12% to $203.6 billion(1), representing more than half of all global
pharmaceutical sales in 2002.

The U.S. market is Elan's most important market. Please refer to Note 2 to the
Consolidated Financial Statements for an analysis of revenue by geographic
region. For this reason, the factors discussed below, such as "Government
Regulation" and "Product Approval Process", place emphasis on requirements in
the United States.


GOVERNMENT REGULATION

The pharmaceutical industry is subject to significant regulation by
international, national, state and local governmental regulatory agencies.
Pharmaceutical product registration is primarily concerned with the safety,
efficacy and quality of new drugs and devices, and, in some countries, their
pricing. A product must generally


- --------------------------------------------------------------------------------
6


- --------------------------------------------------------------------------------

undergo extensive clinical trials before it can be approved for marketing. The
process of developing a new pharmaceutical product, from idea to
commercialisation, can take in excess of ten years. This period varies
considerably from case to case and from country to country.

An application for registration includes specific details concerning not only
the chemical composition, but also the manufacturing plant and procedures
involved in the production of the product. The time from submission of an
application to commercialisation of the product is typically two years or
longer. After a product has been approved by the regulatory authorities and has
been launched, it is a condition of the product approval that all aspects
relating to its safety, efficacy and quality remain under review.

Governmental authorities, including the U.S. Food and Drug Administration
("FDA") and comparable regulatory authorities in other countries, regulate the
design, development, testing, manufacturing and marketing of pharmaceutical
products. For example, the Federal Food, Drug and Cosmetic Act ("FDCA"), the
Public Health Service Act, the Controlled Substances Act and other federal
statutes and regulations impose requirements on the clinical and non-clinical
testing, safety, effectiveness, manufacturing, labelling, storage,
record-keeping, reporting, advertising, marketing, import, export, distribution
and approval of Elan's products in the United States. Non-compliance with
applicable requirements can result in fines and other judicially imposed
sanctions, including product seizures, import restrictions, injunctive actions
and criminal prosecutions. In addition, administrative remedies can involve
requests to recall violative products, the refusal of the government to enter
into supply contracts and/or the refusal to approve pending product approval
applications (such as NDAs and Abbreviated New Drug Applications ("ANDAs") for
drugs, Biologic License Applications ("BLAs") for biological products, or
Premarket Approval Applications and "510(k)s" for medical devices), until
manufacturing or other alleged deficiencies are brought into compliance. The
FDA also has the authority to cause the withdrawal of approval of a marketed
product or to impose labelling restrictions.

In addition, the U.S. Centers for Disease Control and Prevention regulate
select biologics and toxins. This includes registration and inspection of
facilities involved in the transfer or receipt of select agents. Select agents
are subject to specific regulations for packaging, labelling and transport.
Non-compliance with applicable requirements could result in criminal penalties
and the disallowance of research and manufacturing of clinical products.
Exemptions are provided for select agents used for a legitimate medical purpose
or for biomedical research, such as toxins for medical use and vaccines.

Certain in vitro diagnostic products and certain delivery systems, such as
MEDIPAD, are regulated or potentially regulated in the United States under the
FDCA as medical devices. These products are subject to pre-marketing and
post-marketing requirements. Among other things, medical devices are subject to
quality system requirements, including design control and good manufacturing
practices, and to requirements for adverse event reporting by manufacturers,
distributors and user facilities. The failure to adhere to these requirements
can result in a refusal of permission to market and the imposition of sanctions,
including seizure, recall notification, replacement or refund, injunction, and
civil and criminal penalties. Additionally, as a condition to marketing or
continued marketing, the FDA could impose certain post-market surveillance
and/or tracking requirements, which could significantly increase the regulatory
costs associated with a product. Under the FDCA, it is also possible for a given
product to be regulated both as a drug and a medical device or as a biologic and
medical device. In vitro diagnostic products are also subject to certain
requirements under the Clinical Laboratory Improvement Act of 1988, as amended
("CLIA"), relating to test complexity and risk.

The pricing of pharmaceutical products is regulated in many countries. The
mechanism of price regulation varies. For example, certain countries regulate
the price of individual products while in other countries prices are controlled
by limiting overall company profitability. In the United States, while there
are limited indirect federal government price controls over private sector
purchases of drugs, there have been ongoing discussions on potential reforms of
the healthcare system, including the pricing of pharmaceuticals, which could
result, directly or indirectly, in the implementation of price controls on a
larger number of pharmaceutical products. Certain states are attempting to
impose requirements, processes, or systems that would result in indirect price
controls. It is not possible to predict future regulatory action on the pricing
of pharmaceutical products.

In June 2002, Elan entered into a settlement with the U.S. Federal Trade
Commission ("FTC") resolving the FTC's investigation of a licensing arrangement
between Elan and Biovail Corporation ("Biovail") relating to nifedipine, a
generic version of the hypertension drug Adalat CC. The

- --------------------------------------------------------------------------------
ELAN CORPORATION, PLC 2002 ANNUAL REPORT AND FORM 20-F                         7


OPERATING REVIEW
- --------------------------------------------------------------------------------

settlement is reflected in a consent order which, by its terms, does not
constitute an admission by Elan that any law had been violated, and does not
provide for monetary fines or penalties. Elan continues to satisfy all of the
terms of the consent order, including launching its 30mg and 60mg nifedipine
products through Watson in September 2002.

On 2 June 2001, Elan received a letter from the FTC stating that the FTC was
conducting a non-public investigation to determine "whether Brightstone Pharma,
Inc., Elan Corporation or others may have engaged in an effort to restrain trade
by entering into an agreement which may restrict the ability of Brightstone or
others to market a bioequivalent or generic version of Naprelan." In October
2001, counsel for Elan met informally with the FTC staff to discuss the matter.
No further communication from the FTC was received until December 2002, when
Elan received a subpoena duces tecum from the FTC for the production of
documents related to Naprelan. Elan has produced documents in response to the
subpoena and has been communicating with the FTC relating to the investigation.
Elan does not believe that it is feasible to predict or determine the outcome of
the investigation and any possible effect on Elan's business, or reasonable to
estimate the amounts or potential range of loss, if any, with respect to the
resolution of the investigation.

On 13 March 2003, Elan received notification from the FTC that the FTC's Bureau
of Competition was conducting an investigation to determine whether Elan, King
or any other person was engaging in unfair methods of competition in violation
of Section 5 of the Federal Trade Commission Act, including, among other things,
by preventing or slowing generic competition to Skelaxin. The FTC's stated focus
of the investigation was Elan's listing in the FDA's Approved Drug Products with
Therapeutic Equivalence Evaluations ("Orange Book") of at least one patent for
Skelaxin, and other actions with regard to the FDA regulatory process. On 8 May
2003, Elan received notification from the FTC that it had discontinued that
portion of its investigation concerning whether Elan wrongfully listed its
patent for Skelaxin in the Orange Book. Elan continues to co-operate with the
FTC regarding matters unrelated to the Orange Book listing of the Skelaxin
patent. Elan does not believe that it is feasible to predict or determine the
outcome of the remaining portion of the investigation and any possible effect on
the Group's business or reasonably estimate the amounts or potential range of
loss, if any, with respect to the resolution of the investigation.

PRODUCT APPROVAL PROCESS

Preclinical tests assess the potential safety and efficacy of a product
candidate in animal models. The results of these studies must be submitted to
the FDA as part of an IND before human testing may proceed.


PRODUCT APPROVAL PROCESS

The stages of testing required before a pharmaceutical product can be marketed
in the United States are generally as follows:

- --------------------------------------------------------------------------------
PHASE OF DEVELOPMENT   DESCRIPTION
- --------------------------------------------------------------------------------
Preclinical            Animal studies and laboratory tests to evaluate safety
                       and efficacy, demonstrate activity of a product
                       candidate and identify its chemical and physical
                       properties
- --------------------------------------------------------------------------------
Phase I                Clinical studies to test safety profile of drug in humans
- --------------------------------------------------------------------------------
Phase II               Clinical studies conducted with groups of patients to
                       determine preliminary efficacy, dosage and expanded
                       evidence of safety
- --------------------------------------------------------------------------------
Phase III              Larger scale clinical studies conducted in patients to
                       provide sufficient data for statistical proof of efficacy
                       and safety
- --------------------------------------------------------------------------------

For ethical, scientific and legal reasons, animal studies are required in the
discovery and safety evaluation of new medicines. Elan's policy is to seek
alternatives to animal studies through the replacement of animal models with
non-animal models. Alternatives used include various in vitro cell culture
assays. If animal studies are unavoidable, Elan seeks to refine the animal
models used to either reduce the number of animals utilised or to eliminate or
lessen animal discomfort.

Under U.S. law, an IND must be submitted to the FDA and become effective before
human clinical trials may commence. U.S. law further requires that studies
conducted to support approval for product marketing be "adequate and well
controlled." In general, this means that either a placebo or a product already
approved for the treatment of the disease or condition under study must be used
as a reference control. Studies must also be conducted in compliance with good
clinical practice ("GCP") requirements, and adverse event and other reporting
requirements must be followed.

The clinical trial process can take three to ten years or more to complete, and
there can be no


- --------------------------------------------------------------------------------
8


- --------------------------------------------------------------------------------

assurance that the data collected will be in compliance with GCP regulations,
will demonstrate that the product is safe or effective, or, in the case of a
biologic product, pure and potent, or will provide sufficient data to support
FDA approval of the product. The FDA may place clinical trials on hold at any
point in this process if, among other reasons, it concludes that clinical
subjects are being exposed to an unacceptable health risk. Trials may also be
terminated by institutional review boards, who must review and approve all
research involving human subjects. Side effects or adverse events that are
reported during clinical trials can delay, impede, or prevent marketing
authorisation.

The results of the preclinical and clinical testing (described in the table on
page 8), along with information regarding the manufacturing of the product and
proposed product labelling, are evaluated and, if determined appropriate,
submitted to the FDA through a licence application such as an NDA. In certain
cases an ANDA can be filed in lieu of filing an NDA. An ANDA relies on
bioequivalency tests that compare the applicant's drug with an already approved
reference drug rather than on clinical safety and efficacy studies. An ANDA
might be available to Elan for a new formulation of a drug for which
bioequivalent forms have already been approved by the FDA. In responding to
applications for approval, the FDA could grant marketing approval, approve the
product for a narrower indication, impose labelling or distribution
restrictions, request additional information, require post-approval (Phase IV)
studies or deny the application. Applications are often referred to an outside
FDA advisory committee of independent experts prior to the FDA acting on the
application. Similar systems are in place for the testing and approval of
biologics and medical devices.

There can be no marketing in the United States of any drug, biologic or device
for which a marketing application is required until the application is approved
by the FDA. Until an application is actually approved, there can be no
assurance that the information requested and submitted will be considered
adequate by the FDA. Additionally, any significant change in the approved
product or in how it is manufactured, including changes in formulation or the
site of manufacture, generally require prior FDA approval. The packaging and
labelling of all products developed by Elan are also subject to FDA approval
and ongoing regulation.

In the United States, under the Prescription Drug User Fee Act and the Medical
Device User Fee and Modernization Act, the FDA receives fees for reviewing
product applications and supplements thereto, as well as annual fees for
commercial manufacturing establishments and for approved products. These fees
can be significant. For example, the NDA or BLA review fee alone can exceed
$500,000, although certain deferrals, waivers and reductions may be available.
Even when user fees are significant, they do not generally constitute a major
expense relative to the overall cost associated with product development and
regulatory approval.

Whether or not FDA approval has been obtained, approval of a pharmaceutical
product by comparable regulatory authorities in other countries outside the
United States must be obtained prior to the marketing of the product in those
countries. The approval procedure varies from country to country. It can involve
additional testing and the time required can differ from that required for FDA
approval. Although there are procedures for unified filings for European Union
("EU") countries, in general, most other countries have their own procedures and
requirements.

Once a product has been approved, significant legal and regulatory requirements
apply in order to market a product. In the United States these include, among
other things, requirements related to adverse event and other reporting,
product advertising and promotion, and ongoing adherence to current Good
Manufacturing Practice ("cGMP") requirements, as well as the need to submit
appropriate new or supplemental applications and obtain FDA approval for
certain changes to the approved product, product labelling or manufacturing
process. Adverse events that are reported after marketing authorisation can
result in additional limitations being placed on a product's use and,
potentially, withdrawal of the product from the market. Any adverse event,
either before or after marketing authorisation, can result in product liability
claims against the Company.

The FDA also enforces the requirements of the Prescription Drug Marketing Act,
which, among other things, imposes various requirements in connection with the
distribution of product samples to physicians.

Sales, marketing and scientific/educational grant programmes must comply with
the Medicare-Medicaid Anti-Fraud and Abuse Act, as amended, the False Claims
Act, as amended, and similar state laws. Pricing and rebate programmes must
comply with the Medicaid rebate requirements of the Omnibus Budget
Reconciliation Act of 1990, as amended. If products are made available to
authorised users of the Federal Supply Schedule of the

General Services Administration, additional laws and requirements apply.

MANUFACTURING

Each manufacturing establishment, including any contract manufacturers, used to
manufacture a product must be listed in the product application. In the United
States, this means that each manufacturing establishment must be listed in the
drug, biologic, or device application, and must be registered with the FDA. The
application will not be approved until the FDA conducts a manufacturing
inspection, approves the applicable manufacturing process for the product, and
determines that the facility is in compliance with cGMP requirements. If the
manufacturing facilities and processes fail to pass the FDA inspection, the FDA
will not grant approval to market the product. All facilities are also subject
to periodic regulatory inspections to ensure ongoing compliance with cGMP.

Elan currently has manufacturing facilities in Ireland, the United States,
Switzerland and Italy.

At 31 December 2002, Elan employed 887 people in its manufacturing and supply
activities, almost half of these in Athlone, Ireland. This facility is the
primary location for the manufacture of oral solid dosage products, including
instant, controlled-release and oral microparticulate products. Additional
dosage capabilities may be added as required to support future product
introductions. Elan's facility in Gainesville, Georgia, United States, provides
additional oral controlled-release dosage product manufacturing capability and
is registered with the U.S. Drug Enforcement Administration for the
manufacture, packaging and distribution of Schedule II controlled drugs. Elan
also manufactures Myobloc in the United States. Elan's facility in Switzerland
is the primary location for the manufacture of effervescent and fast melt oral
dosage products. Elan's facility in Italy manufactures tablets, liquids,
creams, ointments and powders. Elan disposed of a manufacturing facility in
Indianapolis, Indiana, United States during 2002 as part of the disposal of
Abelcet. Elan disposed of a transdermal dosage products manufacturing facility
in Miramar, Florida, United States in July 2003 to Nitto Americas, Inc. ("Nitto
Americas"), the U.S. subsidiary of Nitto Denko Corporation, as part of the
disposal of a transdermal technology business.

Capital expenditures at Elan's manufacturing sites amounted to approximately
$119 million in 2002, mainly at the Athlone facility, where a new building to
produce existing and future Elan marketed products was completed.

All facilities and manufacturing techniques used for the manufacture of products
and devices for clinical use or for sale in the United States must be operated
in conformity with cGMP regulations. These are FDA regulations governing the
production of pharmaceutical products. Elan's facilities are also subject to
periodic regulatory inspections to ensure ongoing compliance with cGMP
regulations. In May 2001, Elan Holdings, Inc. ("Elan Holdings"), a wholly owned
subsidiary of Elan, Donal J. Geaney, then chairman and chief executive officer
of Elan, William C. Clark, then president, operations, and two then employees of
Elan Holdings, Hal Herring and Cheryl Schuster, entered into a consent decree of
permanent injunction with the U.S. Attorney for the Northern District of
Georgia, on behalf of the FDA, relating to alleged violations of cGMP at Elan's
Georgia, United States facility. The facility manufactured, and continues to
manufacture, verapamil hydrochloride controlled-release capsules used in the
treatment of high blood pressure. The consent decree does not represent an
admission by Elan Holdings of any of the allegations set forth in the decree.
Under the terms of the consent decree, which will continue in effect until at
least May 2006, Elan Holdings is permanently enjoined from violating cGMP
regulations. In addition, Elan Holdings is required to engage an independent
expert, subject to FDA approval, to conduct inspections of the facility at least
annually through May 2004, in order to ensure the facility's compliance with
cGMP. The first of these inspections was completed and reported upon by the
independent expert to the FDA on 3 September 2002. A corrective action plan was
prepared and sent to the FDA in response to this inspection. A second
independent consultant audit occurred in May 2003 and was reported upon by the
independent expert to the FDA on 14 August 2003. In response to this inspection
a corrective action plan is being prepared and will be sent to the FDA. During
the term of the consent decree, Elan expects that the facility will be subject
to increased FDA inspections and, under the terms of the consent decree, Elan
will be required to reimburse the FDA for its costs related to these
inspections. Elan believes that, during the term of the consent decree, the FDA
will continue to process approvals for products to be manufactured at the
facility. For example, during 2002 the FDA approved Avinza and Ritalin LA, which
are being manufactured at the Gainesville, Georgia facility.

SALES AND MARKETING

At 31 December 2002, Elan's sales forces were re-configured as a result of the
implementation of the recovery plan.

- --------------------------------------------------------------------------------

- --------------------------------------------------------------------------------

SALES AND MARKETING

Prior to commencing the recovery plan in mid-2002, Elan marketed its products
through five focused sales forces in the United States. The U.S. sales forces
promoted the following brands:




- ------------------------------------------------------------------------------------------------------------
                      PRIMARY                                           SPECIALTY/        CLINICAL SALES

- ------------------------------------------------------------------------------------------------------------


Going forward, Elan's sales forces will continue to be re-configured. The exact
configuration and number of employees will depend upon the products disposed of
under the recovery plan. However, following the implementation of the recovery
plan, Elan's sales force will be significantly smaller than in 2002.

PATENTS AND INTELLECTUAL PROPERTY RIGHTS

Intellectual property is a vital asset for Elan. Elan's competitive position
depends on its ability to obtain patents on its current and future technologies
and products, to defend its patents, to protect its trade secrets and to
operate without infringing the proprietary rights of others. In addition, under
a number of licence agreements for its drug delivery products, Elan's failure
to obtain patents on the drug delivery product would reduce the royalty rate
that Elan receives on sales of such product.

Elan's products are sold around the world under brand-name, logo and certain
product design trademarks that Elan considers in the aggregate to be of
material importance. Trademark protection continues in some countries for as
long as the mark is used and, in other countries, for as long as it is
registered. Registrations generally are for fixed, but renewable, terms.

Elan owns or licenses a number of U.S. and foreign patents. These patents
cover:

o  Pharmaceuticals and other products and their uses;
o  Pharmaceutical formulations; and
o  Product manufacturing processes.

Patents for individual products extend for varying periods according to the
date of patent filing or grant and the legal term of patents in various
countries. The actual protection afforded by a patent, which can vary from
country to country, depends upon the type of patent, the scope of its coverage
and the availability of legal remedies in the country.

In some instances, there are later-expiring patents relating to these products
directed to particular forms or compositions of the drug or to methods of
manufacturing or using the drug in the treatment of further diseases or
conditions. Such patents may not protect Elan's drug from generic drug
competition after the expiration of the basic patent.

The basic U.S. patent for Maxipime expires in 2007. However, two formulation
U.S. patents covering Maxipime expire in 2008.

In June 2002, Elan announced that Eon Labs, Inc. ("Eon") received FDA approval
to market a generic alternative for Zanaflex. A number of other generic
applications for Zanaflex have since received approval from the FDA. Zanaflex
represented approximately 4% and 5% of Elan's total revenue and product
revenue, respectively, in 2002. Arising from the approval of generic
alternatives for Zanaflex, Elan has experienced a significant decline in the
sales and profitability of this product. This significant decline is expected
to continue in 2003. For example, product revenue from Zanaflex was $0.8
million for the first quarter of 2003 compared to $53.7 million for the first
quarter of 2002. In the event that products competitive to any of the Group's
other products are introduced, Elan would expect a significant decline in the
sales and profitability of such products.

As part of its normal business activity, Elan monitors competitor activity

carefully and will enforce its intellectual property rights whenever
appropriate.

COMPETITION

The pharmaceutical industry is characterised by intense competition and rapid
technological change. Elan's principal pharmaceutical competitors consist of
major international companies, as well as smaller research companies and
generic drug manufacturers. A drug may be subject to competition from
alternative therapies during the period of patent protection or regulatory
exclusivity and, thereafter, it may be subject to further competition from
generic products. Generic competitors do not have to bear the same level of
research and development and other expenses associated with bringing a new
branded product to market. As a result, they can charge much less for a
competing version of our product. Managed care organisations typically favour
generics over brand name drugs, and governments encourage, or under some
circumstances mandate, the use of generic products, thereby reducing the sales
of branded products that are no longer patent protected or protected by other
regulatory exclusivity. Additionally, generic competitors can challenge
existing patent protection or other regulatory exclusivity. Governmental and
other pressures toward the dispensing of generic products may rapidly and
significantly reduce, or slow the growth in, the sales of certain of our
products not protected by patents or other regulatory exclusivity and may
adversely affect Elan's future results.

Elan's drug delivery activities have also faced increasing competition in
recent years as pharmaceutical companies have become increasingly interested in
the development and commercialisation of products incorporating advanced or
novel drug delivery systems.

Elan's competitive position depends, in part, upon its continuing ability to
discover, acquire and develop innovative, cost-effective new products, as well
as new indications and product improvements protected by patents and other
intellectual property rights. Elan also competes on the basis of price and
product differentiation, and through our sales and marketing organisation that
provides information to medical professionals and launches new products.

DISTRIBUTION

Elan sells its pharmaceutical products primarily to drug wholesalers and
retailers, hospitals, clinics, government agencies and managed care providers.
Wholesalers are Elan's main customers. Elan's revenue reflects the demand from
these wholesalers and similar purchasers to meet the in-market consumption of
Elan's products and to reflect the level of inventory that wholesalers and
similar purchasers of Elan's products carry. Changes in the levels of inventory
can directly impact Elan's revenue and could result in Elan's revenue not
reflecting in-market consumption of its products.

Elan generally manufactures its drug delivery products for licencees and
distributors but does not usually engage in any direct sales of drug delivery
products.

RAW MATERIALS AND PRODUCT SUPPLY

Raw materials and supplies are generally available in quantities adequate to
meet the needs of Elan's business. However, Elan does not have dual sourcing or
manufacturing for many of its raw materials or products. Elan is also dependent
on third party manufacturers for most of the pharmaceutical products that Elan
markets and for raw materials. An inability to obtain raw materials or product
supply could have a material adverse impact on Elan's business, financial
condition and results of operations.

During the year, supply constraints at third party manufacturing facilities
adversely affected product revenue from Maxipime, Azactam, and also the
portfolio of pain products ("Pain Portfolio") acquired from Roxane Laboratories
Inc. ("Roxane"). Supplies of Maxipime and Azactam recovered during the fourth
quarter of 2002.


- --------------------------------------------------------------------------------

- --------------------------------------------------------------------------------

Supply conditions related to the Pain Portfolio improved during the fourth
quarter of 2002 and Elan continues to work closely with the supplier to resolve
the supply issues that arose during 2002.

EMPLOYEES

On 31 December 2002, Elan had 3,623 employees worldwide, of whom 867 were
engaged in research and development activities, 887 were engaged in
manufacturing and supply activities, 1,259 were engaged in sales and marketing
activities and the remainder worked in general and administrative areas. The
number of employees has been reduced from approximately 4,700 employees in July
2002 as a result of the implementation of the recovery plan.

BUSINESS VENTURES

Since 1996, Elan has pursued collaborations with biotechnology, drug delivery
and pharmaceutical companies in order to leverage Elan's drug delivery
technologies and its proprietary neurological and oncology research, and to
access complementary or synergistic research and development programmes in
Elan's areas of expertise. Elan has historically referred to this programme in
a number of ways, including as a joint venture programme, a business venture
programme and a strategic licensing programme. For the purposes of these
Consolidated Financial Statements, this programme will be referred to as the
"business venture programme". Elan has not entered into any new business
ventures under the business venture programme since mid-2001.

In 2002, as part of the recovery plan, Elan completed a review of its business
venture portfolio to conserve cash and reflect the reduced scope of Elan's
activities. As a result, it is Elan's intention to restructure or terminate
substantially all of its business ventures with the aim of substantially
reducing or eliminating future cash outlays by Elan. The restructuring process
and any terms agreed have been the result of negotiations between Elan and the
respective business venture parents. As such, the agreed terms arising from the
restructuring process vary between different business venture relationships.
Typically, as part of the termination of a business venture, the technologies
contributed by the business venture parent and Elan are returned, the
technology developed in the business venture is transferred to the business
venture parent and/or Elan, and Elan transfers its interest in the business
venture to the business venture parent in exchange for a continuing interest in
the product or technology previously in the business venture, such as a
royalty. There can be no assurance that all business venture relationships can
be restructured or terminated on commercially reasonable terms, or at all.
There were 55 business ventures in place prior to the announcement of the
recovery plan on 31 July 2002. To date, Elan has formally restructured 36
business venture relationships.

As it is Elan's intention to restructure or terminate substantially all of its
business venture relationships, the description of the business venture
programme below is generally no longer applicable and is described in the past
tense.

The business venture programme generally involved licensing drug delivery
technologies and know-how, or pharmaceutical research and development assets, to
a newly formed subsidiary (the "business venture") of an emerging biotechnology,
drug delivery or pharmaceutical company (the "business venture parent") and the
establishment of a joint development collaboration.

Contemporaneously with the licensing and collaborative transaction, Elan
typically made an investment in the business venture. Investments in business
ventures were in various forms. Prior to mid 1999, these investments were
generally in the form of voting common stock. Subsequently, these investments
were in the form of non-voting preferred stock convertible into common stock
after a period of two years. Elan typically held an initial fully diluted
equity interest of 19.9% in the business venture. Elan also typically made a
contemporaneous investment in the business venture parent in the form of common
equity and convertible/exchangeable preferred stock and/or convertible/
exchangeable debt. The convertible/exchangeable securities in the business
venture parent were generally convertible, at Elan's option, into common equity
of the business venture parent or exchangeable for up to 30.1% of the common
equity in the business venture, potentially bringing Elan's fully diluted
equity interest in the business venture up to 50%. In many transactions, if
Elan chose to exchange the convertible/exchangeable securities in the business
venture parent into common equity of the business venture, then it would be
required to pay the business venture parent an amount equal to 30.1% of the
cumulative operating funding of the business venture to the date of exchange
such that Elan and the business venture parent would have shared equally (on a
cumulative basis) in such funding. Elan sold certain of its investments in the
business ventures and the business venture parents to EPIL II in June 2000 and
to EPIL III in March 2001. EPIL II and EPIL III are securitisation entities and
the investments are held by EPIL II and EPIL III as security for outstanding

indebtedness issued by the entities. For additional information regarding these
special purpose entities, please refer to Notes 16 and 33 to the Consolidated
Financial Statements.

The business venture generally conducted research and development activities
using its technologies and proprietary know-how in an agreed research field.
Elan's partner, the business venture parent, principally managed the business
venture. The technologies and proprietary know-how of the business venture were
in-licensed by the business venture from Elan and the business venture parent.
On formation, a number of contracts were entered into to govern the
in-licensing of intellectual property assets to the business venture from Elan
and the business venture parent.

Development of products and technologies for pharmaceutical applications
involves risk. The nature of pharmaceutical development, with stringent
regulatory constraints and guidelines designed to protect the health and safety
of patients and those working with the products, means that development
activities are costly and time consuming. Elan's portfolio of business ventures
allowed it to diversify the risks associated with product development.
Individual development programmes within the business ventures had varying
degrees of success and failure. Elan and the business venture parent would
typically work together using commercially reasonable efforts and their
combined technical, regulatory and clinical expertise to increase the
likelihood of success of the business ventures. This could lead to changes in
the direction of a development programme, adding or substituting technologies
or products and redirection of clinical programmes as deemed necessary.

The business venture, the business venture parent and Elan continually reviewed
the progress of the research and development activities in the business
venture. As part of this review, the parties could decide that it was not
commercially or technically practical to continue to support the business
venture.

Elan received and recorded initial revenue from the business ventures set out
in the tables on pages 16 to 18 of $Nil, $172.5 million and $321.2 million for
2002, 2001 and 2000, respectively. Elan's initial investments in the business
ventures and the business venture parents were $Nil, $229.2 million and $435.7
million for 2002, 2001 and 2000, respectively.

The business ventures typically had the following operational structure. The
board of directors of a business venture was generally comprised of a majority
of directors from the business venture parent and one director nominated by
Elan. For a quorum, the presence of the Elan nominated director was required.
The business plan required the approval of the board of directors of the
business venture, including the Elan nominated director. This approval was
subject to the directors' fiduciary duty to the business venture. The contracts
of establishment provided for subsequent reviews, either annually or more
frequently, of the business plan and required the continuing approval by the
Elan nominated director. The business ventures also typically had a management
committee and/or research and development committee. These committees generally
provided for equal representation by Elan and the business venture parent. The
committees had responsibility for day to day activities of the business venture
and for the implementation of the business plan. At their inception, the
business ventures typically had no funds after payment of the initial fee to
Elan. The operating funding of the business venture was provided by the business
venture parent and Elan, subject to the approval of both parties. Funding was
generally utilised to pay for research and development activities. Typically,
such subsequent financial support was provided in proportion to the respective
fully diluted ownership of the business venture by the business venture parent
and Elan (typically 80.1% and 19.9%, respectively). Elan expensed the subsequent
funding it provided directly to the business venture. This was expensed within
the interest and other expense line. Elan expensed $23.9 million, $24.6 million
and $10.0 million of subsequent business venture funding in 2002, 2001 and 2000,
respectively. If both Elan and the business venture parent agreed to provide
subsequent financial support to the business venture through their ongoing
approval of a business plan, then, if requested by the business venture parent,
Elan was required to make additional investments in the business venture parent,
typically in the form of convertible debt, in an amount equal to the business
venture parent's proportion of such subsequent financial support, the proceeds
of which the business venture parent was required to use to fund its proportion
of the subsequent support of the business venture. This amount was recorded by
Elan as a financial asset. Elan provided additional financing of $83.4 million,
$92.2 million and $41.3 million to business venture parents in 2002, 2001 and
2000, respectively. As a consequence of the implementation of the recovery plan,
Elan expects that the amount of additional financing it will provide to the
business ventures and business venture parents in 2003 will be less than $10.0
million.

The business ventures incurred research and development expenditures of
approximately $125 million, $125 million and $70 million in 2002, 2001 and
2000, respectively. While the business ventures and the business venture
parents were generally responsible for ongoing


- --------------------------------------------------------------------------------

- --------------------------------------------------------------------------------

research and development activities, they could request that Elan conduct
research and development on their behalf. If Elan undertook such work, the work
was typically charged to the business venture at pre-determined rates, which
were set to recover Elan's costs plus a mark-up. Elan received research revenue
from the business ventures of $13.4 million, $15.0 million and $15.4 million in
2002, 2001 and 2000, respectively.

Investments in the business ventures and the business venture parents were made
at fair value. The fair value of investments was typically initially determined
by Elan using established financial methodologies, including quoted market
prices for quoted equity securities. Unquoted equity investments and non-traded
securities of public entities were assessed using methodologies including the
Black-Scholes option-pricing model, the valuation achieved in the most recent
private placement by an investee, an assessment of the impact of general
private equity market conditions, and discounted projected future cash flow
models.

Subsequent to Elan's investment in a business venture and business venture
parent, the values of the investments have been typically determined
periodically, but not less frequently than yearly, by an independent financial
institution using methodologies similar to those described above.

The tables on pages 16 to 18 set forth certain information regarding the 36
business ventures that were formed in 2001 and 2000. No new business ventures
were formed in 2002. Of all of the business ventures formed since the
commencement of the business venture programme in 1996, 55 were still in place
prior to the announcement of the recovery plan on 31 July 2002. It is Elan's
intention to restructure or terminate substantially all of its business
ventures. To date Elan has formally restructured 36 business venture
relationships.

Elan recognised exceptional charges in its profit and loss account for 2002 to
reflect impairments to the Group's investment portfolio, including investments
held by EPIL II and EPIL III. This includes impairment charges relating to
investments in business ventures and business venture parent companies of
$114.4 million and $880.0 million, respectively.

COMMERCIAL--AMERICAS

Pharmaceutical commercial activities include the marketing of products in the
therapeutic areas of neurology, pain management and infectious diseases.

Product revenue from Elan's main product lines, including divested products,
increased by 6% to $650.6 million for 2002 from $612.1 million for 2001.
Divested products are products which have been sold or which are subject to an
agreement to divest.

Please refer to the Financial Review for further information on product revenue.

Neurology/Pain Management

CNS diseases are classified into two types: neurological, which includes AD,
MS, Parkinson's disease and epilepsy; and psychiatric disorders, which includes
depression, anxiety disorders and schizophrenia. Elan's focus on CNS diseases
is concentrated on neurological conditions and currently encompasses AD,
epilepsy, MS and muscle spasticity.

PAIN PORTFOLIO

In September 2001, Elan acquired the Pain Portfolio from Roxane. These products
are marketed in the United States. The portfolio of products includes
Roxicodone and Oramorph. Elan's revenue from the Pain Portfolio for 2002
amounted to $59.8 million.

ZONEGRAN

Elan licensed Zonegran for the United States and Europe from Dainippon.
Zonegran was launched in the United States in May 2000 as an adjunctive therapy
in the treatment of partial epileptic seizures in adults. In 2002, Zonegran
generated 0.4 million prescriptions, an increase of 107%, making it the third
fastest growing anti-epileptic drug in the United States2. U.S. revenue for
Zonegran for 2002 amounted to $43.1 million. Zonegran has been marketed by
Dainippon in Japan since 1989. A European MAA filing for Zonegran for use as an
adjunctive therapy in partial seizures is anticipated prior to the end of 2003.
In August 2003, Elan received approval from the FDA to market two new lower
dosage strengths, 25 mg and 50 mg. of Zonegran in addition to the original
100 mg capsule.

The following table sets forth Elan's aggregate U.S. revenue from its main

acute treatment of migraine. In March 2002, Elan and UCB Pharma, Inc. ("UCB")
entered into an agreement to co-promote Frova. The companies launched Frova
during the second quarter of 2002. Elan markets Frova, pursuant to its
co-promotion agreement with UCB. Elan's revenue from Frova for 2002 amounted to
$11.2 million.

ZANAFLEX

In June 2002, Elan announced that Eon received FDA approval to market a generic
alternative for Zanaflex. A number of other generic applications for Zanaflex
have since received approval from the FDA. Zanaflex represented approximately
4% and 5% of Elan's total revenue and product revenue, respectively, in 2002.
Arising from the approval of generic alternatives for Zanaflex, Elan has
experienced a significant decline in the sales and profitability of this
product. Zanaflex revenue decreased to $56.8 million for 2002 compared to
$161.7 million for 2001. This significant decline is expected to continue in
2003. For example, product revenue from Zanaflex was $0.8 million for the first
quarter of 2003 compared to $53.7 million for the first quarter of 2002.

Skelaxin

Elan acquired Skelaxin through its acquisition of GWC Health, Inc. ("Carnrick")
in 1998. Skelaxin is approved by the FDA as an adjunctive treatment for the
relief of discomfort associated with acute, painful musculoskeletal conditions.
U.S. revenue for Skelaxin increased by 23% to $145.3 million for 2002 from
$117.9 million for 2001. On 12 June 2003, Elan sold Skelaxin to King as part of
the disposition of Elan's primary care franchise.

Sonata

In December 2001, Elan entered into a strategic alliance with Wyeth pursuant to
which Elan assumed responsibility for the U.S. marketing of Sonata, a
non-benzodiazepine hypnotic for the treatment of sleep disorders, which was
launched by Wyeth in 1999. Elan's revenue from Sonata was $92.5 million for
2002. On 12 June 2003, Elan sold Sonata to King as part of the disposition of
Elan's primary care franchise.

Infectious Diseases

Major segments in the infectious diseases market include respiratory infections,
hospital-acquired bacterial infections and fungal infections.

U.S. revenue from Elan's key products within the infectious diseases
therapeutic area decreased by 14% to $176.8 million for 2002 compared
to $204.7 million for 2001.

MAXIPIME

Elan licensed the U.S. marketing rights to Maxipime from Bristol-Myers Squibb
Company ("Bristol-Myers"). Maxipime is a fourth-generation injectable
cephalosporin antibiotic used to treat patients with life-threatening
infections. Pulmonologists, infectious disease specialists, internal medicine
physicians, hematologists and oncologists prescribe Maxipime for patients with
severe hospital-based respiratory and non-respiratory conditions such as
pneumonia, urinary tract infection and febrile neutropenia. An important
attribute of Maxipime is its broad spectrum of activity, including activity
against many pathogens resistant to other antibiotics. U.S. revenue for
Maxipime decreased by 8% to $79.2 million for 2002 from $86.3 million for 2001.
This decrease was due to short term supply issues, which have since been
resolved, together with a change in Elan's discounting strategy, which resulted
in reduced wholesaler inventories.

AZACTAM

Elan licensed the U.S. marketing rights to this injectable product from
Bristol-Myers. Azactam is a monobactam and is principally used by surgeons,
infectious disease specialists and internal medicine physicians to treat
pneumonia, post-surgical infections and septicemia. U.S. revenue for Azactam
decreased by 29% to $33.0 million for 2002 from $46.4 million for 2001. Sales
of Azactam were impacted by short-term supply issues, which have since been
resolved, and generic competitors in its product class.

ABELCET

Elan acquired Abelcet when it acquired The Liposome Company, Inc. ("Liposome")
in May 2000. Abelcet, which is an amphotericin B lipid complex, is used for the
treatment of systemic fungal infections. These infections mainly occur in
immuno-compromised patients such as those undergoing cancer chemotherapy. Elan
recorded U.S. revenue for Abelcet of $64.6 million for 2002, a decrease of 10%
from $72.0 million for 2001.

On 22 November 2002, Elan announced the completion of the sale of its U.S.,
Canadian and any Japanese rights to Abelcet, and certain related assets, to
Enzon. Elan retains its existing rights to market Abelcet in territories outside
of the United States, Canada and Japan.

Dermatology

In June 2002, Elan elected not to exercise its option to acquire certain
dermatology products from GSK, thereby eliminating future product payments of
approximately $180 million. This resulted in rights to these products reverting
to GSK at the end of 2002. Elan will receive no revenues from these products in
2003 and beyond.

Most of Elan's dermatology sales force was transferred to either GSK or Taro
Pharmaceuticals USA, Inc.

COMMERCIAL--NON-U.S.

Elan has a hospital specialty presence in all the major European markets. A
network of distributors in the smaller European markets is being expanded.
Product revenue from Elan's non-U.S. business increased 14% for 2002 to $104.7
million from $91.6 million for 2001.



During 2002 Elan restructured its non-U.S. business to focus on the
requirements of its product pipeline. All primary care businesses were divested
or rationalised. This effort included restructuring in the United Kingdom,
Ireland and Spain.

RESEARCH AND DEVELOPMENT

Biopharmaceutical research and development activities include the discovery and
development of products in the therapeutic areas of neurology, pain management
and autoimmune diseases.

Elan is a proven leader in the advancement and understanding of AD. Other
neurology research and development efforts include work in the areas of
Parkinson's disease, MS and epilepsy. In autoimmune and pain management, Elan
has late-stage development efforts with Antegren and Prialt and an ongoing
commitment to continued research in these areas.

ANTEGREN

Antegren is a humanised monoclonal antibody for use in inflammatory conditions
such as MS and Crohn's disease. Antegren is the first alpha 4 integrin
antagonist in a new class of potential therapeutics known as Selective Adhesion
Molecule ("SAM") inhibitors. Antegren blocks the adhesion of leukocytes
(primarily lymphocytes) to blood vessel walls and thus interrupts the
subsequent migration of lymphocytes into tissues where, in autoimmune diseases
such as MS and Crohn's disease, these cells mediate an inappropriate immune
response against normal tissue.

In August 2000, Elan signed a development and marketing collaboration agreement
with Biogen under which Elan and Biogen are collaborating in the development,
manufacture and commercialisation of Antegren. Under the terms of the
agreement, Elan and Biogen share costs for ongoing development activities. In
2000, Biogen paid a one-time, non-refundable license fee of $15.0 million to
Elan. In 2001 and 2002, Biogen paid $16.0 million and $7.0 million,
respectively, to Elan for the achievement of certain milestones in those years.
Biogen is obligated to pay Elan additional amounts upon the completion of
certain future milestones. If all future milestones were achieved, Biogen would
be required to pay up to an additional $14.0 million over the remaining life of
the agreement.

Crohn's disease is a chronic inflammatory relapsing-remitting disease of the
gastrointestinal tract, commonly affecting both men and women, usually as young
adults. The disease can cause diarrhoea, abdominal pain, fever, and, at times,
rectal bleeding, as well as loss of appetite and subsequent weight loss. Crohn's
disease can result in frequent hospitalisations for patients and may necessitate
surgery.

MS is a disorder involving repeated episodes of inflammation of nervous tissue
in the CNS. This inflammation destroys the myelin sheath or covering of the
nerve cells, leaving multiple areas of scar tissue. The exact cause of the
inflammation associated with MS is unknown.



In January 2003, Antegren was the focus of two separate publications in the New
England Journal of Medicine ("NEJM"). The publications describe Antegren Phase
II clinical study data in Crohn's disease and in MS. The first NEJM publication
of an investigational study in Crohn's disease showed promising results on
disease remission and improved quality of life for patients. The clinical
remission data indicate a maximal response rate of up to 71% where 44% of
Antegren treated patients achieved clinical remission. The MS study results
published in the second

OPERATING REVIEW
- --------------------------------------------------------------------------------

NEJM article indicate that Antegren treatment reduced new inflammatory brain
lesions by up to 93% and produced a reduction of approximately 50% in the number
of patients experiencing relapses for patients with relapsing forms of MS.

Based on the findings in Phase II, Elan and Biogen are conducting four Phase
III trials to evaluate the safety and efficacy of Antegren in both Crohn's
disease and MS. ENACT-1 (Evaluation of Natalizumab in Active Crohn's Disease
Trial -- 1), the largest ever study in Crohn's disease conducted to date, is
fully enrolled with more than 900 patients. This trial evaluated clinical
response and ability to induce remission. On 24 July 2003, Elan and Biogen
announced that the trial did not meet the primary endpoint of "response", as
defined by a 70-point decrease in the Crohn's Disease Activity Index ("CDAI")
at week 10. For additional information on this trial, please refer to Note 29
to the Consolidated Financial Statements. ENACT-2 (Evaluation of Natalizumab As
Continuous Therapy -- 2) will evaluate the duration of effect. ENACT-2 is also
fully enrolled. The two MS trials are both fully enrolled. These trials will
evaluate natalizumab in patients with relapsing-remitting forms of the disease.
AFFIRM (natalizumab safety and efficacy in relapsing-remitting MS) will
evaluate the ability of natalizumab to slow the rate of disability in MS and
reduce the rate of clinical relapses. SENTINEL (safety and efficacy of
natalizumab in combination with Avonex in patients with relapsing-remitting MS)
will determine if the combination of natalizumab and Avonex is more effective
than treatment with Avonex alone in slowing the rate of disability and reducing
the rate of clinical relapses.

Elan believes that Antegren will provide a meaningful advance for patients with
these debilitating diseases.

PRIALT

Prialt is a new type of analgesic in development for the treatment of severe
chronic pain in cancer and AIDS patients, and neuropathic pain resulting from
head injuries or stroke. In June 2000, Elan announced that it had received an
approvable letter from the FDA for Prialt. In January 2002, Elan announced that
it had agreed with the FDA to conduct an additional Phase III clinical trial.
The final Phase III trial for Prialt is currently recruiting patients. Elan
expects to file an NDA in the first quarter of 2004. An MAA has recently been
filed for Europe. The FDA has granted approval for a treatment IND programme.

ZONEGRAN

Zonegran is indicated as an adjunctive therapy for partial epileptic seizures.
However, the class of drugs of which Zonegran is a part has been proven to be
effective in other diseases of the CNS such as mania, migraine and neuropathic
pain. Elan is currently exploring these indications to expand the product's
use. In addition, Elan plans to file an MAA for Zonegran later this year.

ELAN'S AD PROGRAMMES

AD is a degenerative brain disorder that primarily affects older persons. AD can
begin with forgetfulness, can progress into more advanced symptoms, including
confusion, language disturbances, personality and behaviour changes, and
impaired judgement, and can ultimately lead to profound dementia. Patients
eventually are unable to care for themselves and often require
institutionalisation or professional care in the home setting. One of the key
pathological features of AD is the presence of beta-amyloid containing plaque
lesions in the brain tissue of affected patients. Many scientists working in AD
research believe that the beta-amyloid peptide (the building block of plaque) is
causative of the disease.

Approximately four million people in the United States presently have AD,
according to the Alzheimer's Association. Most of these people are over age 65
and almost half of all Americans over age 85 are thought to have AD.

Elan currently has one of the largest research efforts dedicated to developing
pathology-based approaches to the treatment of AD. Elan scientists have
researched approaches to the prevention and treatment of AD since 1987. These
research advances have been discussed in distinguished scientific publications,
such as Nature, and by scientific organisations such as the American Academy of
Neurology.

Elan's extensive knowledge on the processes of beta-amyloid peptide formation
has led to new disease targets and the development of one of the first animal
models of the disease. As a result of this work, Elan has developed several new
therapeutic approaches for the treatment of AD, including an immunotherapeutic
approach targeting the beta-amyloid peptide. In March 2000, a research and
development alliance between Elan and Wyeth, a leader in biopharmaceutical
research and development, was formed to leverage the early preclinical research
demonstrating that AN-1792 reduced and prevented the development of amyloid
plaque in mice, and to discover and develop additional products within the
immunotherapeutic approach.

Elan and Wyeth have formed one of the broadest research alliances in the
pharmaceutical industry to develop


- --------------------------------------------------------------------------------
24


- --------------------------------------------------------------------------------

immunotherapeutic approaches to treat and prevent AD. We are making significant
progress in the Alzheimer's immunotherapy programme and expect to file two INDs
from this programme within the next 15 months. These INDs include the previously
announced monoclonal antibody programme, as well as a novel immunotherapeutic
Abeta peptide conjugate. Elan and Wyeth are leveraging the innovative conjugate
technology that Wyeth uses in some of its other products.

The novel immunotherapeutic approach to treating AD was highlighted in 2002 in
two publications in Nature Medicine. In one of these papers, an independent
group of investigators at the University of Zurich studied a subset of patients
in the Phase IIA study of AN-1792 carried out by Elan and Wyeth (in which dosing
was suspended early in 2002 following reports of inflammation within the CNS).
The authors concluded that most of the patients developed antibodies against
beta-amyloid, which is a critical step in plaque clearance. The investigators
found that the antibodies in the cerebrospinal fluid had unique specificity for
the targeted pathogenic structures containing beta amyloid. In another
independent study from the University of Toronto, the study authors demonstrated
in transgenic mice that the relevant and beneficial immune response to
beta-amyloid can safely be directed to the amino terminus of that peptide.
According to the editorial in Nature Medicine, these two new studies raise the
possibility that a modified immunotherapeutic approach may effectively
counteract AD.

A report published in March 2003 in Nature Medicine summarises the
neuropathology of one patient with AD who participated in the Phase I study
using AN-1792. The paper provides the first evidence that the immune response
generated against the Abeta peptide can elicit clearance of Abeta plaques in
humans. The report also identifies the accumulation of inflammatory cells as
the likely cause of the CNS inflammation seen in approximately 6% of patients.
The accompanying editorial from Dr Brad Hyman's group, which weighs the
potential risks and benefits of AN-1792, commenting on the potential of the
immunotherapeutic approach, states that "These data suggest an astonishingly
powerful effect of the vaccination."

In a separate and independent approach to AD, Elan has also been collaborating
with Pfizer (formerly Pharmacia) since August 2000, focusing on the discovery
of inhibitors of beta secretase, an enzyme associated with the development of
the beta-amyloid peptide. Beta secretase inhibition is considered by many in
the field of AD research to be the premier target for a potential
disease modifying treatment for AD.

Elan's operating results can be affected by a number of factors, including
those described under "Cautionary Factors That May Affect Future Results" and
"Risk Factors".

COMPANY ACQUISITIONS

In 2001 Elan acquired Delsys. In 2000 Elan acquired Dura, Liposome, Neuralab
Limited ("Neuralab"), Quadrant Healthcare, plc, ("Quadrant") and other
companies. For additional information regarding these acquisitions, please
refer to Note 23 to the Consolidated Financial Statements.

CRITICAL ACCOUNTING POLICIES

The Consolidated Financial Statements include certain amounts that are based on
management's best estimates and judgements. Estimates and judgements are used
in determining items such as the carrying values of intangible assets, the
carrying values of financial assets and the accounting for contingencies, among
other items. Because of the judgements and uncertainties inherent in such
estimates, actual results may differ from these estimates.

IRISH GAAP

The estimates and judgements used by Elan in accounting for intangible assets
and financial assets are significant given the carrying values of these assets
in Elan's financial statements. For example, a 10% decrease in the carrying
values of intangible assets or financial assets at 31 December 2002 would have
resulted in an impairment charge of $208.0 million or $80.9 million,
respectively. Intangible assets amounted to $2,079.5 million and $4,526.2
million at 31 December 2002 and 31 December 2001, respectively. Fixed and
current financial assets amounted to $809.4 million and $2,102.0 million at 31
December 2002 and 31 December 2001, respectively.

Intangible Assets and Impairment

The principal judgements and uncertainties affecting Elan's accounting for
intangible assets relate to carrying values. The carrying values of intangible
assets are assessed annually, using discounted cash flows and net realisable
values (estimated sales proceeds less costs to sell). The estimates and
judgements used to assess carrying values include those relating to research
and development risk, commercial risk, revenue and cost projections, the
intention of the Group with respect to the intangible asset, such as the sales
and marketing support for a product or the continued focus or level of
resources for a particular development project or technology, the impact of

competition, including generic competition, the impact of any reorganisation or
change of business focus of the Group, the level of third party interest in
Elan's intangible assets and market conditions.

In July 2002, Elan announced a recovery plan. This resulted in material
impairment charges in Elan's profit and loss account. Where the carrying value
of intangible assets exceeds their recoverable amounts, the carrying values of
those intangible assets have been written down to their recoverable amounts. If
Elan were to use different estimates or judgements, particularly with respect
to expected proceeds from disposals, the likelihood of research and development
success, the likelihood and date of commencement of generic competition or the
impact of any reorganisation or change of business focus, an additional
material impairment charge to the profit and loss account could arise. Elan
believes that it has used reasonable estimates and judgements in assessing the
carrying values of its intangible assets.

Financial Assets and Impairment

The principal judgements and uncertainties affecting Elan's accounting for
financial assets relate to carrying values. In general, Elan's accounting
policy for financial assets is to carry such assets at cost less provision for
impairment in value. The carrying values of financial assets are assessed using
established financial methodologies, including quoted market prices for quoted
equity securities. Unquoted equity investments and non-traded securities of
public entities are typically assessed using methodologies such as the
Black-Scholes option-pricing model, the valuation achieved in the most recent
private placement by an investee, and an assessment of the impact of general
private equity market conditions. The factors affecting carrying values include
both general financial market conditions for pharmaceutical and biotechnology
companies and factors specific to a particular company. Different market
conditions, negative developments or news affecting a specific investee could
result in a material impairment charge for the applicable investment.
Additionally, many of Elan's investments are in emerging drug delivery,
pharmaceutical and biotechnology companies. In assessing the carrying values of
these investments, Elan has assumed that it holds the investments for the
medium to long-term and that no liquidity discount is required. If Elan were to
dispose of investments in a forced sale or in an accelerated manner, it is
likely that material impairment charges would arise. The financial markets for
emerging biotechnology, drug delivery and pharmaceutical companies declined
significantly in 2002. Elan incurred a charge, arising from its investment
portfolio, including those investments held by EPIL II and EPIL III and the
impact of a disposal of investments during 2002 by EPIL III, in its profit and
loss account for 2002 of $1,262.9 million. For additional information on this
investment charge, please refer to Note 3 to the Consolidated Financial
Statements. Elan believes that it has used reasonable estimates and judgements
in assessing the carrying values of its financial assets.

Exceptional Items

Exceptional items are those items that in management's judgement are material
items which derive from events or transactions that fall within the ordinary
activities of the Group and which individually or, if of a similar type, in
aggregate, need to be disclosed by virtue of their size or incidence. Elan
believes that it has used reasonable judgements in determining exceptional
items.

Contingencies

The principal judgements used by Elan in accounting for contingencies include
the likelihood of the contingency occurring and the ability to estimate the
financial impact of such occurrence. Elan's contingencies include shareholder
litigation and an investigation by the SEC. For additional information on these
and other contingencies and litigation, please refer to Notes 24 and 25 to the
Consolidated Financial Statements. As discussed in Note 25 to the Consolidated
Financial Statements, the Group is unable to ascertain the ultimate aggregate
amount of monetary liability or financial impact, if any, of the shareholder
litigation, which seeks damages of material or indeterminate amounts, or the
SEC investigation. The principal judgements and estimates in accounting for the
litigation contingency relate to the Group's assessment of the outcome of the
litigation and the SEC investigation which can evolve over time.

Equity Accounting

Investments in associated undertakings are accounted for under the equity
method where the Company holds voting equity in the investee and exercises
significant influence over the operating and financial policies of the
investee. Significant influence may exist even if the Company owns less than
20% of the investee's equity depending on the existence of factors such as
representation on the board of directors, participation in policy making
processes, material intercompany transactions, interchange of managerial
personnel or technological dependency. Certain circumstances, such as majority
ownership by another company, can offset the impact of such factors. The
determination to use cost or equity accounting requires a significant degree of
judgement on the facts and circumstances of a particular investment. Financial
asset investments which are accounted for under the equity method are stated at
cost, adjusted for the Company's share of the earnings or losses of the
investee after the date of investment, less any provision for impairment in
value.

For additional information regarding Elan's significant accounting policies,
please refer to Note 1 to the Consolidated Financial Statements.

U.S. GAAP

Revenue Recognition

Under U.S. GAAP, the accounting treatment for non-refundable up-front fees was
similar to Irish GAAP prior to 2000. In December 1999, the SEC issued SAB 101
which provides guidance on revenue recognition under U.S. GAAP. Elan adopted
SAB 101 in 2000. SAB 101 generally requires the deferral and amortisation of
up-front fees when there is a continuing involvement by the seller with the
asset disposed of. SAB 101 does not apply under Irish GAAP. Elan defers and
amortises up-front licence fees to the income statement over the "performance
period". The performance period is the period over which Elan expects to
provide services to the licencee. It is determined by the provisions, facts and
circumstances, such as the research and development period, of the relevant
contract. Additionally, under Irish GAAP, revenue from the sale of product
rights and related inventory is recognised when earned and non-refundable. The
same accounting is generally applicable under U.S. GAAP. In certain
circumstances, however, when Elan has continuing involvement with the product,
deferral and amortisation of such revenue may be appropriate.

For additional information on the significant differences between Irish and
U.S. GAAP, please refer to Note 33 to the Consolidated Financial Statements.

SEGMENTAL ANALYSIS

During 2001 and through mid-2002, Elan conducted its operations through two
primary business units; Biopharmaceuticals and Drug Delivery. On 31 July 2002,
Elan announced a recovery plan to restructure its businesses, assets and
balance sheet in order to enable it to meet its financial commitments. With the
implementation of the recovery plan, Elan will focus on three core therapeutic
areas: neurology, pain management and autoimmune diseases. In accordance with
this new focus, the Group was reorganised and two new units were created: Core
Elan and Elan Enterprises.

Core Elan is engaged in pharmaceutical commercial activities and
biopharmaceutical research and development activities. Core Elan is also
engaged in pharmaceutical manufacturing activities at its facility in Athlone,
Ireland. Elan's pharmaceutical commercial activities include the marketing of
products in the therapeutic areas of neurology, pain management and infectious
diseases. Biopharmaceutical research and development activities include the
discovery and development of products in the therapeutic areas of neurology,
pain management and autoimmune diseases. Elan Enterprises is mainly comprised
of Elan's drug delivery businesses and other assets such as business ventures
and non-core pharmaceutical products. Drug delivery activities have
historically included the development, licensing and marketing of drug delivery
products, technologies and services to pharmaceutical industry clients on a
worldwide basis. Elan Enterprises is seeking to dispose of many of these
businesses and assets.

The Group's total revenue of $1,333.0 million (2001: $1,740.7 million) is
comprised of revenue within Core Elan and Elan Enterprises of $951.2 million
(2001: $1,402.5 million) and $381.8 million (2001: $338.2 million),
respectively. Elan's operating loss of $2,290.8 million (2001: $829.7 million)
primarily comprises operating losses incurred by Core Elan and Elan Enterprises
of $2,156.4 million (2001: $667.6 million) and $126.4 million (2001: $154.8
million), respectively.

Core Elan's revenue decreased by 32% to $951.2 million for 2002 from $1,402.5
million for 2001. The decrease in revenue from Zanaflex, Azactam, risk-sharing
arrangements (Pharma Marketing/Autoimmune) and product rationalisations was
$104.9 million, $13.4 million, $116.4 million and $213.6 million, respectively,
for 2002 compared to 2001. Core Elan incurred an operating loss of $2,156.4
million for 2002, compared with an operating loss of $667.6 million for 2001,
primarily due to exceptional charges in 2002 of $1,659.2 million compared to
$638.0 million for 2001. Exceptional charges in 2002 relate primarily to the
impairment of intangible assets arising from Elan's recovery plan initiated
during 2002 and, in 2001, relate primarily to the impairment of goodwill
related to the acquisition of Dura, the impairment of acquired intellectual
property ("acquired IP") related to the acquisition of Neurex Corporation
("Neurex"), the impairment of product intangibles relating to Naprelan and
Ceclor CD and the rationalisation of Core Elan's activities. Core Elan's
operating loss before exceptional items increased to $497.2 million for 2002
from $29.6 million for 2001, reflecting the impact of decreased revenue.

Elan Enterprises' revenue increased by 13% to $381.8 million for 2002 from
$338.2 million for 2001 mainly due to revenue from product disposals arising
from Elan's recovery plan related to Avinza, Actiq and Adalat of $154.7 million
and increased revenue from the diagnostics business offset by a decrease in
licence fee income from $173.6 million for 2001 to $7.1 million for 2002. Elan
Enterprises incurred an operating loss of $126.4 million in 2002, compared with
an operating loss of $154.8 million in 2001, primarily due to exceptional
charges in 2002 of $137.1 million compared to $318.5 million for 2001 offset by
lower licence fee revenue in 2002. Exceptional charges in 2002 relate primarily
to the impairment of intangible assets arising from Elan's recovery plan
initiated during 2002 and, in 2001, relate primarily to exceptional charges for
the impairment of acquired IP related to the acquisition of Sano Corporation
("Sano"). Elan Enterprises' operating profit before exceptional items decreased
by 93% to $10.7 million for 2002 from $163.7 million for 2001, primarily
reflecting reduced licence fee revenue.

Product Revenue

Product revenue decreased by 14% to $1,204.5 million for 2002 from $1,407.0
million for 2001.

(A) Revenue from Retained Products

Revenue from retained products was $516.6 million for 2002 compared with $610.5
million for 2001. Combined revenue from Maxipime and Azactam was $112.2 million
for 2002 compared to $132.7 million for 2001, a decrease of 15%. This decrease
was due to supply issues during 2002, which have since been resolved, together
with a change in Elan's discounting strategy, which resulted in reduced
wholesaler inventories. Zonegran revenue was $43.1 million for 2002 compared to
$37.8 million for 2001, an increase of 14%. The percentage increase in
prescription demand for this product in 2002 over 2001 was higher than the
percentage increase in product revenue, due to a change in Elan's discounting
strategy, which resulted in reduced wholesaler inventories. Revenue from the
Pain Portfolio, which was acquired from Roxane in September 2001, was $59.8
million for 2002 compared to $15.4 million for 2001. Myobloc product revenue
increased 67% for 2002 to $17.5 million from $10.5 million for 2001 as a result
of increased promotion. Frova, which was launched in the United States in May
2002 under a co-promotion agreement between Elan and UCB, generated revenue of
$11.2 million for 2002. Generic competitor products to Zanaflex were launched
in the United States during 2002. This resulted in a decrease in Zanaflex
revenue to $56.8 million for 2002 compared to $161.7 million for 2001. This
significant decline is expected to continue in 2003. For example, product
revenue from Zanaflex was $0.8 million for the first quarter of 2003 compared
to $53.7 million for the first quarter of 2002. Non-U.S. product revenue
increased 14% for 2002 to $104.7 million from $91.6 million for 2001.

(B) Revenue from Divested Products

On 30 January 2003, Elan announced that it had agreed to sell its primary care
franchise, principally consisting of its U.S. and Puerto Rican rights to
Skelaxin and Sonata, related inventory and related rights to enhanced
formulations of these products, to King. On 17 March 2003, Elan commenced a
lawsuit against King to compel King to complete its purchase of the primary
care franchise. On 19 May 2003, Elan and King agreed to proceed with the
transaction on amended terms and on 12 June 2003 the transaction was completed.
Effective upon the closing of the transaction, all claims under the pending
litigation were released and Elan and King dismissed the litigation with
prejudice. During 2002, product revenue from Skelaxin and Sonata was $237.8
million (2001: $120.2 million).

During 2002, Elan divested its dermatology and Athena Diagnostics businesses
and its U.S., Canadian and any Japanese rights to Abelcet, and announced that
it had agreed to dispose of its Elan Diagnostics business. These businesses
contributed $182.8 million to product revenue for 2002 (2001: $185.5 million),
representing revenues before they were divested. Aside from product revenue of
approximately $9 million from Elan Diagnostics prior to its disposal on 29
April 2003, Elan will not record any revenue from these businesses in 2003.
Elan retained its product rights to Abelcet in Europe and will continue to
record European revenue from this product.


- --------------------------------------------------------------------------------
32


- --------------------------------------------------------------------------------

On 9 December 2002, Elan announced the amendment of the terms of its
development, licence and supply agreement with Ligand regarding Avinza. Elan
received a cash payment of $100.0 million from Ligand in return for a reduction
in the ongoing royalty rate from the previous level of 30% of net sales of
Avinza in the United States and Canada to approximately 10%. In addition, Elan
agreed to forego its option to negotiate a co-promotion agreement with Ligand
for Avinza in the United States and Canada. Elan will continue to manufacture
the product in its Gainesville facility. Net of the write-off of the related
intangible assets, Elan recorded net revenue of $75.6 million on the closing of
this transaction.

On 3 October 2002, Elan announced that it sold its rights to Actiq in twelve
territories, principally in Europe, to Anesta. At the date of disposal, Actiq
was marketed by Elan in the United Kingdom, Ireland and Germany. Net of the
write-off of the related intangible assets, Elan recorded revenue of $40.3
million on the closing of this transaction.

On 23 August 2002, Elan announced a licensing agreement with Watson for
exclusive marketing rights to the 30 mg and 60 mg dosage strengths of Elan's
extended-release nifedipine tablets in the United States. Elan received $45.0
million in cash from Watson. Elan will continue to manufacture the products in
its Athlone facility. Net of the write-off of the related intangible assets,
Elan recorded revenue of $38.8 million on the closing of this transaction.

Product rationalisation revenue was $17.8 million for 2002 compared to $231.4
million for 2001. For additional information on product rationalisations,
please refer to pages 43 to 46.

Product sales of rationalised products, which represents revenue prior to
rationalisation, decreased by 69% to $32.0 million for 2002 from $101.7 million
for 2001. As the product rationalisation programme initiated in 2001 has now
been completed, Elan will not record any product sales of rationalised products
in 2003.

(C) Co-promotion Fees

Product revenue from product co-promotion and marketing activities, which
resulted from Elan's risk-sharing arrangements with Pharma Marketing and
Autoimmune, decreased by 60% to $62.8 million for 2002 from $157.7 million for
2001. Elan will not receive any future revenue from either Pharma Marketing or
Autoimmune.

Contract Revenue

Contract revenue decreased by 61% to $128.5 million for 2002 from $333.7
million for 2001, primarily as no licence fees were received from business
ventures in 2002. Elan received up front licence fees of $7.1 million in 2002
compared to $173.6 million for 2001. Contract revenue from Pharma Marketing and
Autoimmune decreased by 37% to $37.2 million for 2002 from $58.7 million for
2001. Elan will not receive any future revenue from either Pharma Marketing or
Autoimmune. Research revenue and milestones amounted to $84.2 million in 2002
compared to $101.4 million in 2001.

Major Customers

Cardinal Health, Inc. ("Cardinal Health"), Amerisource Bergen Corporation
("Amerisource Bergen") and McKesson Corporation ("McKesson") accounted for
approximately 13%, 13% and 12%, respectively, of Elan's total revenue for 2002.
Cardinal Health and Pharma Marketing accounted for approximately 14% and 11%,
respectively, of Elan's total revenue for 2001. No other customer accounted for
more than 10% of total revenue for 2002 or 2001.

COST OF SALES

Cost of sales, after exceptional items, increased by 25% to $483.1 million for
2002 from $386.8 million for 2001. The increase was 15% before exceptional
items of $66.1 million for 2002 and $22.8 million for 2001. Gross margin on
total revenue, before exceptional items, was approximately 64% for 2002 and 76%
for 2001. Gross margin on total revenue, after exceptional items, was 64% for
2002 and 78% for 2001. Gross margin on product revenue, before exceptional
items, decreased to 60% for 2002 from 69% for 2001. Gross margin on product
revenue, after exceptional items, decreased to 60% in 2002 from 73% in 2001.
The reduction in gross margin on product revenue reflects changes in the mix of
product revenue, in particular the decrease in product revenue from
risk-sharing arrangements and from Zanaflex. The reduction in gross margin on
total revenue reflects changes in the mix of revenue, in particular the
decrease in licence fees and in revenue from risk-sharing arrangements.

SELLING, GENERAL AND ADMINISTRATIVE EXPENSES

Selling, general and administrative expenses, after exceptional items,
increased by 47% to $2,623.4 million for 2002 from $1,781.7 million for 2001.
The increase was 20% before exceptional items of $1,788.0 million for 2002 and
$1,084.2 million for 2001, principally

FINANCIAL REVIEW
- --------------------------------------------------------------------------------

reflecting increased sales and marketing costs in Elan's U.S.
Biopharmaceuticals business arising from the inclusion of a full year's sales
and marketing costs for 2002 for Sonata (Elan assumed marketing responsibility
for this product in December 2001) and the Pain Portfolio (Elan acquired these
products in September 2001), together with the launch of Frova during 2002.

RESEARCH AND DEVELOPMENT EXPENSES

Research and development expenses, after exceptional items, increased by 29% to
$517.3 million for 2002 from $401.9 million for 2001. The increase was 25%
before exceptional items of $114.7 million for 2002 and $78.6 million for 2001,
principally reflecting increased expenditure on Elan's research and development
projects, including Antegren.

EXCEPTIONAL ITEMS

Exceptional items are those items that in management's judgement are material
items which derive from events or transactions that fall within the ordinary
activities of the Group and which individually or, if of a similar type, in
aggregate, need to be disclosed by virtue of their size or incidence.

2002

In 2002, Elan incurred net exceptional charges of $2,939.4 million.

The exceptional items for 2002 mainly relate to the:

o   Implementation of Elan's recovery plan. Elan announced this recovery plan in
    July 2002;

o   Significant decline during 2002 in the financial markets for investments in
    emerging biotechnology, drug delivery and pharmaceutical companies; and

o   Introduction of generic competitors to some of Elan's products.

On 31 July 2002, Elan announced a recovery plan to restructure its businesses,
assets and balance sheet. Elan decided to focus on three core therapeutic
areas. These are neurology, pain management and autoimmune diseases. A key
element of the recovery plan is the divestiture of businesses and products. The
exceptional charges and revenue arising from the recovery plan mainly relate to
the:

o   Sale of businesses and products. The carrying value of these assets have
    been written down, where applicable, to their estimated recoverable amounts.
    Exceptional revenue arises from the proceeds received on the disposal of
    products;

o   Discontinuance of businesses or the decision not to exercise an option to
    acquire a product. For example, Elan decided not to exercise its option to
    acquire certain dermatology products from GSK;

o   Rationalisation and restructuring expenses incurred from a reduction in the
    scope of Elan's activities, a reduction in employee numbers and related
    write-downs in the carrying value of assets;

o   Simplification of Elan's business such as the termination of the Autoimmune
    risk-sharing arrangement; and

o   Termination or restructuring of substantially all of Elan's business
    ventures.

(A) Revenue

Exceptional product revenue of $172.5 million for 2002 includes $154.7 million
from product disposals arising from Elan's recovery plan, as well as $17.8
million relating to product rationalisations. For additional information on
product rationalisations, please refer to pages 43 to 46.

On 9 December 2002, Elan announced the amendment of the terms of its
development, licence and supply agreement with Ligand regarding Avinza. Elan
received a cash payment of $100.0 million from Ligand, in return for a
reduction in the ongoing royalty rate from the previous level of 30% of net
sales of Avinza in the United States and Canada to approximately 10%. In
addition, Elan agreed to forego its option to negotiate a co-promotion
agreement with Ligand for Avinza in the United States and Canada. Elan will
continue to manufacture the product in its Gainesville facility. Net of the
write-off of the related intangible assets, Elan recorded exceptional product
revenue of $75.6 million on the closing of this transaction.

On 3 October 2002, Elan announced that it sold its rights to Actiq in twelve
territories, principally in Europe, to Anesta. At the date of disposal, Actiq
was marketed by Elan in the United Kingdom, Ireland and Germany. Net of the
write-off of the related intangible assets, Elan recorded exceptional product
revenue of $40.3 million on the closing of this transaction.

On 23 August 2002, Elan announced a licensing agreement with Watson for
exclusive marketing rights to the 30 mg and 60 mg dosage strengths of Elan's
extended-release nifedipine tablets in the United States. Elan received $45.0
million in cash from Watson. Elan will continue to manufacture the products in
its Athlone facility. Net of the write-off of the related intangible assets,
Elan recorded exceptional product revenue of $38.8 million on the closing of
this transaction.

FINANCIAL REVIEW
- --------------------------------------------------------------------------------

(B) Cost of Sales

Exceptional cost of sales includes a charge of $43.3 million related to the
write-off of Zanaflex inventories due to the impact of generic competition
during 2002. Other exceptional cost of sales includes $8.0 million on the write
down of the intangible asset for Mysoline, following generic competition for
this product, $5.7 million on the impairment of certain fixed assets,
severance/relocation costs of $8.4 million and other exceptional cost of sales
of $0.7 million.

(C) Selling, General and Administrative

Exceptional selling, general and administrative expenses were $1,788.0 million.
$1,536.7 million of the exceptional expenses relate to impairment charges
arising on write-downs of intangible assets. Other exceptional selling, general
and administrative expenses were $251.3 million. These include the purchase of
royalty rights from Autoimmune, fixed asset write-downs and similar costs
arising from the restructuring of the Group as part of the recovery plan. They
also include legal costs related to the SEC investigation, shareholder
litigation, and litigation provisions.

Impairment charges to goodwill relating to the acquisitions of Dura, Liposome,
Quadrant and Sano were $854.9 million, $111.8 million, $78.2 million and $2.4
million, respectively. Impairment charges to acquired IP arising from the
acquisitions of Sano and Axogen, were $87.4 million and $28.4 million,
respectively. Other impairments to goodwill totalled $19.1 million. Impairment
charges to patents and licences arising on write-downs of the product
intangibles for the Pain Portfolio, Myobloc, Naprelan, Myambutol, dermatology
products and Frova were $86.3 million, $77.7 million, $35.7 million, $32.7
million, $29.8 million and $29.4 million, respectively. Other impairments to
patents and licences totalled $62.9 million.

Dura

Elan acquired Dura in November 2000 for $1,590.7 million. Dura was a specialty
pharmaceutical company engaged in the marketing and sale of prescription
products for the treatment of infectious diseases and respiratory conditions.
The Dura acquisition added over 500 hospital and primary care sales
representatives to Elan's sales and marketing infrastructure and broadened
Elan's portfolio of marketed products. The purchase price was primarily
allocated to goodwill and patents and licences. In 2002, Elan wrote down
goodwill relating to the acquisition of Dura by $854.9 million. Elan acquired
Dura in order to significantly expand its sales and marketing infrastructure.
Elan's recovery plan aims to create a research and development based
biopharmaceutical company focused on neurology, pain management and autoimmune
diseases. Therefore, Elan has decided to significantly reduce its sales and
marketing infrastructure. For example, during 2002, Elan decided to dispose of
its primary care franchise and related infrastructure. As a result of such
reductions in Elan's sales and marketing capability, the carrying value of the
Dura goodwill has been impaired.

Liposome

Elan acquired Liposome in May 2000 for $731.8 million, which included a
milestone payment of $54.0 million paid on the receipt of marketing and pricing
approval for Myocet in certain countries of the EU. Liposome was a
biotechnology company engaged in the development, manufacturing and marketing
of therapeutic products to treat cancer and related diseases. The purchase
price was primarily allocated to goodwill and patents and licences. In 2002,
under its recovery plan, Elan disposed of its U.S., Canadian and any Japanese
rights to Abelcet, and certain related assets, and allocated $119.0 million of
goodwill to the sale of the Abelcet business based on the estimated relative
fair value of the Abelcet rights disposed. In 2002, Elan wrote down the
remaining goodwill arising from the acquisition of Liposome by $111.8 million,
as under its recovery plan Elan has decided to close its oncology research and
development business. The residual value for goodwill of $86.8 million is
supported by European rights to Abelcet and Myocet.

Quadrant

Elan acquired Quadrant in December 2000 for $86.0 million. Quadrant was a drug
delivery company with proprietary formulation technology applicable to
pulmonary, oral and parenteral routes of administration. The purchase price was
primarily allocated to goodwill. In 2002, Elan wrote down goodwill arising from
the acquisition of Quadrant by $78.2 million to $Nil, as under its recovery
plan Elan decided to dispose of or close the Quadrant business. This business
was sold to a company managed by former employees of the business in July 2003.

Sano

Elan acquired Sano in February 1998 for $434.6 million. Sano was developing
transdermal drug delivery products. The purchase price was primarily allocated
to acquired IP. In 2002, Elan wrote down acquired IP and goodwill arising from
the acquisition of Sano by $87.4 million and $2.4 million, respectively, as
under its recovery plan Elan decided to dispose of its transdermal business.
This business was sold to Nitto Americas in July 2003.

- --------------------------------------------------------------------------------

Axogen

Elan acquired Axogen in December 1999 for $268.4 million. The purchase price
was primarily allocated to patents and licences and acquired IP. In 2002, Elan
wrote down acquired IP relating to Myobloc, arising from the acquisition of
Axogen, by $28.4 million. Elan also wrote down $77.7 million in respect of
other Myobloc intangible assets. The carrying value of Myobloc was written down
due to lower than expected revenue from this product for 2002 and as under its
recovery plan Elan may dispose of this product.

Other Products

The intangible asset for the Pain Portfolio was written down due to supply
difficulties since its acquisition in 2001, leading to diminished selling
support from Elan as well as changed commercial expectations related to generic
competition. Naprelan and Myambutol have been written down due to the impact of
generic competition on these products in 2002 and reduced projected revenue and
profitability from these products. Frova was written down to reflect reduced
projected revenue and profitability from this product. In June 2002, Elan
elected not to exercise its purchase option to acquire certain dermatology
products from GSK. This resulted in rights to all products reverting to GSK at
the end of 2002. As a result of this decision, Elan wrote down the related
product intangible by $29.8 million to $Nil.

Autoimmune

In July 2002, Elan announced the termination of all agreements relating to the
risk-sharing arrangement with Autoimmune. The royalty obligations to Autoimmune
were terminated. The total consideration for the royalty rights was $121.0
million which, after taking account of the redemption of Elan's investment of
$38.5 million in Autoimmune, resulted in a net cash cost of $82.5 million. Elan
expensed $121.0 million as an exceptional selling, general and administrative
expense arising from the acquisition of Autoimmune.

Litigation

Elan recorded a provision during 2002 of $19.0 million relating to litigation
with Schwarz Pharma, Inc. ("Schwarz"), Allergan, Inc. and Allergan Sales, LLC
(collectively, "Allergan") and shareholder derivative actions. For additional
information on these litigations, please refer to Note 25 to the Consolidated
Financial Statements.

(D) Research and Development

Exceptional research and development expenses were $114.7 million. These mainly
relate to product and goodwill impairments of $59.3 million and $10.6 million,
respectively, together with fixed asset write-downs of $11.6 million and
severance/relocation costs.

In September 2001, Elan acquired Delsys for $50.0 million. Delsys was formed in
1995 and was engaged in developing novel manufacturing technology. During 2002,
Elan recorded an impairment charge for the intangible assets relating to Delsys
of $45.7 million, as under its recovery plan, Elan has decided to close Delsys.

(E) Other Ordinary Activities

Elan recognised a gain of $77.9 million on the disposal of Athena Diagnostics
and the Abelcet business. In November 2002, Elan completed the sale of its
U.S., Canadian and any Japanese rights to Abelcet, and certain related assets,
to Enzon. Elan received a net cash payment of $360.0 million from Enzon,
representing the total consideration, after agreed price adjustments. The gain
amounted to $12.7 million. In December 2002, Elan together with the other
stockholders of Elan's subsidiary, Athena Diagnostics, completed the sale of
all of the outstanding stock of Athena Diagnostics to Behrman. Elan realised
net cash proceeds of $81.8 million and a net gain of $65.2 million.

Elan has restated its U.S. GAAP financial results as of and for the fiscal year
ended 31 December 2001 to consolidate EPIL III from its date of establishment
on 15 March 2001. Under U.S. GAAP, EPIL III has historically been accounted for
by Elan as a qualifying special purpose entity and has not, therefore, been
consolidated. In addition, Elan has adjusted its previously announced unaudited
U.S. GAAP financial information as of and for the fiscal year ended 31 December
2002 to give effect to the consolidation of EPIL III and to consolidate Shelly
Bay Holdings Ltd. ("Shelly Bay"), an entity established by Elan, from 29 June
2002 through 30 September 2002. Shelly Bay acquired certain financial assets
from EPIL III on 29 June 2002. Under Irish GAAP, EPIL III has been accounted
for as a consolidated subsidiary since its date of establishment in accordance
with the requirements of FRS 5, "Reporting the Substance of Transactions" ("FRS
5"). Therefore, the 2001 restatement does not affect the Irish GAAP financial
information contained in this Annual Report and Form 20-F. For additional
information regarding the restatement and the adjustments, please refer to Note
33 to the Consolidated Financial Statements.

ELAN CORPORATION, PLC 2002 ANNUAL REPORT AND FORM 20-F                        37


FINANCIAL REVIEW
- --------------------------------------------------------------------------------

In March 2001, Elan transferred a portfolio of equity and debt securities to
EPIL III, a wholly owned subsidiary of Elan. EPIL III issued $160.0 million in
aggregate principal amount of Series A Guaranteed Notes, $190.0 million in
aggregate principal amount of Series B Guaranteed Notes and $200.0 million in
aggregate principal amount of Series C Guaranteed Notes. The Series A
Guaranteed Notes matured on 29 June 2002. To fund the repayment of the notes,
on 29 June 2002 EPIL III transferred certain financial assets, consisting of
certain of the securities included in the portfolio transferred to EPIL III, to
Shelly Bay and Shelly Bay made a $148.0 million cash payment to EPIL III. EPIL
III used the proceeds from the payment by Shelly Bay, together with existing
cash of $12.0 million, to repay the Series A Guaranteed Notes. The assets
transferred by EPIL III to Shelly Bay had a carrying value under Irish GAAP of
$223.4 million.

The documents that established EPIL III required that EPIL III dispose of
financial assets in order to repay the Series A Guaranteed Notes at maturity.
The documents also mandated the order in which the assets were to be sold prior
to the maturity date for the Series A Guaranteed Notes. However, due to a
number of factors, including the inability of Elan and EPIL III to locate the
list mandating the order of disposal of the financial assets, the disposal
process was commenced and completed over the one-week period ending on 29 June
2002. Although Elan, as servicing agent for EPIL III, contacted a number of
third parties regarding their potential interest in purchasing financial assets
from EPIL III, each of those parties indicated that they would not be able to
complete a due diligence analysis of the issuers of the financial assets to be
sold, or to receive all necessary internal approvals to complete the purchase,
on a timely basis.

Therefore, in an effort to enable EPIL III to dispose of the financial assets,
Elan determined that it would be necessary to provide non-recourse credit
support to third parties who would agree to purchase financial assets from EPIL
III. Credit support was offered to a number of potential purchasers of the
financial assets. However, ultimately, only Shelly Bay possessed the ability to
complete the transaction on a timely basis.

Elan established Shelly Bay specifically for the purpose of acquiring financial
assets from EPIL III. All of the capital stock of Shelly Bay was issued to its
sole shareholder. Elan did not own any capital stock of Shelly Bay and did not
have a representative on Shelly Bay's board of directors. In addition, the sole
shareholder of Shelly Bay had no previous contact with Elan. However, as
further described below, Elan possessed all of the financial risk of the Shelly
Bay transaction. Similar to all other potential purchasers contacted by Elan,
the sole shareholder of Shelly Bay was unwilling to invest capital to acquire
the financial assets until a due diligence analysis of the issuers of the
financial assets had been completed. Therefore, the sole shareholder of Shelly
Bay made no substantive capital investment in Shelly Bay and, although Shelly
Bay possessed all of the potential financial benefits of the transaction,
neither Shelly Bay nor its sole shareholder had any financial risk in the
transaction.

Elan believed that any failure by EPIL III to dispose of financial assets prior
to 29 June 2002 could potentially adversely impact the non-consolidated
accounting status of EPIL III under U.S. GAAP and could result in defaults
under Elan's debt instruments.

Under the terms of the transaction, Shelly Bay acquired certain financial
assets from EPIL III on 29 June 2002 and made a cash payment to EPIL III of
$148.0 million. Shelly Bay financed the entire purchase price of the financial
assets, together with the funds necessary to pay interest and other costs on
the loan to its maturity date, through borrowings under a $153.0 million
non-recourse bank loan facility maturing on 30 September 2002. Elan provided a
full and unconditional guarantee to the bank to support Shelly Bay's obligation
to repay the loan and provided $153.0 million in cash collateral to the bank to
secure Elan's obligations under its guarantee. Upon the closing of the
transaction, Elan paid to Shelly Bay approximately $1 million to reimburse
Shelly Bay for the expenses expected to be incurred by it in connection with
the transaction. In addition, Elan irrevocably waived all rights of recourse
against Shelly Bay in the event that it failed to repay the bank loan at
maturity.

The cash payment made by Shelly Bay in connection with its acquisition of the
financial assets was based upon a valuation conducted by Elan. The valuation
utilised customary, widely-accepted valuation methodologies and required that
Elan make certain judgements and assumptions regarding the financial assets.
Elan did not receive any independent verification of the valuation at the time
of the transaction. In addition, EPIL III did not receive any bids for the
financial assets to be disposed of.

Upon the closing of the transaction, Shelly Bay's assets consisted solely of
the financial assets purchased from EPIL III. Under the terms of the
transaction, Shelly Bay was required to complete a due diligence analysis of
the issuers of the securities prior to 15 September 2002. Shelly Bay had the
right to either elect, on or prior to 15 September 2002, to retain the
financial assets on a long-term basis or to dispose of the financial assets
prior to 30 September 2002.



In the event that Shelly Bay elected to retain the financial assets, it was
required, within 15 days of the election, to obtain alternative financing in an
amount equal to the value, as of 29 June 2002, of the assets being retained, as
determined by an independent appraiser engaged by Shelly Bay. The net cash
proceeds received by Shelly Bay from any alternative financing were required to
be applied to repay amounts outstanding under Shelly Bay's bank loan.


- --------------------------------------------------------------------------------
38


- --------------------------------------------------------------------------------

In the event that Shelly Bay elected to dispose of the financial assets prior
to 30 September 2002, Shelly Bay was required to apply the net proceeds from
the dispositions to repay amounts outstanding under its bank loan. The
transaction agreements contained no limitation on the price at which any
financial asset could be sold by Shelly Bay or the party to whom any financial
asset could be sold. In addition, Elan agreed that it had no right to object to
the disposition of any financial asset, the party to whom it was disposed of or
the price obtained for the disposition.

Given the non-recourse nature of the Shelly Bay bank loan, Elan possessed all
of the financial risk of the transaction under its guarantee of the bank loan,
and the cash collateral provided by Elan to secure the guarantee, in the event
of any shortfall in the aggregate proceeds received by Shelly Bay from the
refinancing or disposition of the financial assets. Although Shelly Bay
possessed all of the potential financial benefits of the transaction, neither
Shelly Bay nor its sole shareholder had any financial risk in the transaction.

As required by the terms of the transaction, Shelly Bay engaged an independent
appraiser to value the financial assets as of 29 June 2002. The appraisal,
which was prepared in early September 2002, valued the financial assets at $8.2
million.

Shelly Bay did not elect, under the terms of the transaction, to retain any of
the financial assets and obtain alternative financing in an amount equal to the
independent appraiser's valuation. Rather, by 30 September 2002, Shelly Bay had
disposed of all of the financial assets for aggregate net proceeds of $9.3
million. A number of the financial assets were disposed of, for net proceeds of
$1.8 million, to an affiliate of Shelly Bay. The remainder of the financial
assets were sold to third parties and in open market transactions. As described
above, the transaction agreements contained no limitation on the price at which
any financial asset could be sold by Shelly Bay or the party to whom any
financial asset could be sold, including to an affiliate of Shelly Bay. In
addition, Elan agreed that it had no right to object to the disposition of any
financial asset, the party to whom it was disposed of or the price obtained for
the disposition.

As a result of the disposition of the financial assets by Shelly Bay for
aggregate net proceeds of $9.3 million, on 30 September 2002, Elan made a cash
payment of $141.6 million to satisfy its obligation under its guarantee. Under
the terms of the transaction agreements, Elan has no further obligation under
the guarantee and has no recourse to Shelly Bay or to its sole shareholder
arising from Elan's payment under the guarantee. The loss on the sale of the
securities was $217.0 million under Irish GAAP including the $141.6 million
under the guarantee.

(F) Net Interest

Exceptional net interest and other expenses were $1,004.0 million.

This includes a charge of $1,045.9 million relating to investments in Elan's
investment portfolio, including the investments held by EPIL II and EPIL III.
The financial markets for emerging biotechnology, drug delivery and
pharmaceutical companies declined significantly during 2002. The investment
impairment charge mainly reflects this significant decline in the financial
markets and also the impact of weak financial markets on the ability of
emerging biotechnology, drug delivery and pharmaceutical companies to raise
finance. The charge also includes impairments relating to investments in
business ventures and business venture parents.The investment impairments
comprise $215.4 million, $575.4 million and $255.1 million in relation to
quoted investments, unquoted investments and loans, and securitised investments
respectively.

Offsetting this charge was a net gain of $37.7 million on the repurchase of
$318.6 million in principal amount at maturity of LYONs. These LYONs, having an
accreted value of $190.1 million at the date of purchase, were purchased at an
aggregate cost of $149.8 million, resulting in the net gain of $37.7 million
after related costs. For further information regarding the LYONs, please refer
to Note 16 to the Consolidated Financial Statements.

- ------------------------------------------------------------------------------------------------------------------------------


(A) Revenue

Exceptional revenue in 2001 primarily relates to product rationalisation
revenue of $231.4 million.

(B) Cost of Sales

The exceptional cost of sales is primarily comprised of $15.6 million relating
to product rationalisation revenue.

(C) Selling, General and Administrative

Exceptional selling, general and administrative expenses were $1,084.2 million.
$1,009.8 million of the exceptional charges relate to impairment charges
arising on write-downs of intangible assets. Impairment charges to acquired IP
arising from the acquisitions of Neurex and Sano were $500.0 million and $285.2
million, respectively. Impairment charges to patents and licences arising on
write-downs of the product intangibles for Naprelan, Ceclor CD and Myambutol
were $81.0 million, $94.2 million and $44.4 million, respectively. Other
impairments to patents and licences amounted to $5.0 million. Other exceptional
selling, general and administrative expenses were $74.4 million. These mainly
relate to severance, integration, relocation and similar costs and asset
write-downs arising from the integration of Elan's U.S. Biopharmaceuticals
business.

Elan acquired Neurex in August 1998 for $810.0 million. Neurex was developing
Prialt. The purchase price was primarily allocated to acquired IP. In 2001,
Elan wrote down acquired IP arising from the acquisition of Neurex by $500.0
million. This write-down was due to delays in the product launch schedule and
reduced revenue projections for Prialt.

Elan acquired Sano in February 1998 for $434.6 million. Sano was developing
transdermal drug delivery products. The purchase price was primarily allocated
to acquired IP. In 2001, Elan wrote down acquired IP arising from the
acquisition of Sano by $285.2 million. The write-down was due to reduced
revenue projections from products under development and to Elan's decision to
focus its research and development efforts in other areas.

Ceclor CD and Myambutol were written down due to the impact of generic
competition on these products during 2001. Generic versions of each of these
products were approved and launched in 2001, which reduced projected revenues
and profitability from these products. Revenue from Ceclor CD declined by $26.0
million in 2001, from $39.4 million in 2000 to $13.4 million in 2001. Naprelan
was written down due to lower than forecasted revenues in 2001 and reduced
projected revenue and profitability from this product. The level of promotional
support for a product can have a significant impact on the level of revenue
generated from that product. Elan does not expect to provide any significant
promotional support for Naprelan in the future and this has been reflected in
the projections for this product. Revenue from Naprelan declined by $33.6
million in 2001, from $41.8 million in 2000 to $8.2 million in 2001.


- --------------------------------------------------------------------------------
40


- --------------------------------------------------------------------------------

(D) Research and Development

Exceptional research and development expenses were $78.6 million in 2001. These
mainly relate to severance, integration and similar costs and asset write-downs
arising from the re-organisation, closure or scaling back of various drug
delivery programmes and sites. Also included were costs of certain research
programmes that Elan does not intend to complete. These were the estimated
costs incurred pending closure or sale.

(E) Net Interest

Exceptional net interest and other expenses were $6.8 million in 2001. These
mainly relate to costs associated with the redemption in March 2001 of the
4.75% exchangeable notes (the "4.75% Exchangeable Notes") of Athena
Neurosciences, Inc., a wholly owned subsidiary of Elan ("Athena
Neurosciences").

NET INTEREST AND OTHER EXPENSE

Net interest and other expense was $1,170.7 million for 2002 compared to $50.4
million for 2001.

Interest payable and similar charges increased by 349% to $1,309.2 million for
2002 from $291.9 million for 2001, primarily reflecting investment related
charges of $1,045.9 million in 2002 compared with $24.1 million in 2001.
Interest payable for 2002 includes $47.1 million (2001: $40.3 million) on the
7.25% senior notes due 2008 (the "7.25% Senior Notes"), issued by Athena
Neurosciences Finance, LLC, ("Athena Finance") an indirect wholly owned
subsidiary of Elan, in February 2001; $37.2 million (2001: $35.4 million) on
the EPIL III Notes issued in March 2001; and $43.0 million (2001: $43.0
million) on the EPIL II Notes issued in June 2000. Elan expenses the subsequent
funding it provides directly to business ventures. This is expensed within the
interest and other expense line. Elan expensed $23.9 million and $24.6 million
for this subsequent funding, in 2002 and 2001, respectively.

Income from financial assets decreased by 43% to $138.5 million for 2002 from
$241.5 million for 2001. Interest and other income decreased to $86.3 million
for 2002 from $159.2 million in 2001, reflecting lower cash balances and
reduced investment income during 2002. Gains on financial assets decreased to
$12.1 million in 2002 from $80.5 million in 2001. Gains on financial assets in
2001 includes $31.5 million for the sale of approximately 20% of Athena
Diagnostics in December 2001. Income from financial assets for 2002 also
included a gain of $37.7 million on the repurchase of LYONs. Foreign exchange
gains amounted to $2.4 million in 2002 and $1.8 million in 2001.

For additional information regarding net interest and other expense, please
refer to Note 5 to the Consolidated Financial Statements.

For additional information regarding indebtedness, please refer to Note 16 to
the Consolidated Financial Statements and to "Debt Facilities" in this
Financial Review.

TAXATION

Tax on profit on ordinary activities increased by 14% to $19.8 million for 2002
from $17.4 million for 2001. The tax charges reflected tax at standard rates in
the jurisdictions in which Elan operates, income derived from Irish patents,
which is exempt from tax, foreign withholding tax and the availability of tax
losses. Elan's Irish patent derived income was exempt from taxation pursuant to
Irish legislation, which exempts from Irish taxation income derived from
qualifying patents. Currently, there is no termination date in effect for such
exemption.

For additional information regarding taxation, please refer to Note 8 to the
Consolidated Financial Statements.

DISCONTINUED OPERATIONS

Following the sale of Athena Diagnostics and the Abelcet business (U.S.,
Canadian and any Japanese rights to Abelcet and certain related assets), and
the return of the dermatology products to GSK, the results of these operations
for the year and comparatives have been reported separately as discontinued
operations. For additional information on discontinued operations, please refer
to Note 7 to the Consolidated Financial Statements.

RETAINED LOSS

Retained loss for the year, after exceptional items, was $3,615.1 million for
2002 compared to a loss of $887.2 million for 2001. Before exceptional items,
retained loss was $675.7 million for 2002 compared to a retained profit of
$77.4 million for 2001. Basic loss per

REVENUE

Product Revenue

Product revenue, after exceptional items in 2001, increased by 70% to $1,407.0
million for 2001 from $825.6 million for 2000, primarily resulting from product
revenue from product rationalisations, the inclusion for a full year in 2001 of
product revenue from corporate acquisitions made during 2000, primarily Dura
and Liposome, increased revenue from product co-promotion and marketing
activities and organic growth. The increase was 43% before exceptional product
revenue of $225.8 million in 2001. Product rationalisations, which consisted of
the sale of certain product rights and related inventory as described below
through outright sale or pursuant to distribution and royalty arrangements,
contributed $231.4 million to product revenue in 2001. This amount has been
included in exceptional items. Product revenue arising from the acquisitions of
Dura and Liposome increased by 775% and 37% to $279.1 million and $87.2
million, respectively, for 2001 as compared to 2000. Product revenue from
Zanaflex and Skelaxin increased by 78% and 45% to $161.7 million and $117.9
million, respectively, for 2001 as compared to 2000. Product revenue from
product co-promotion and marketing activities, which resulted from Elan's
risk-sharing arrangements with Pharma Marketing and Autoimmune, increased by
158% to $157.7 million in 2001 from $61.1 million in 2000. The increase in
product revenue for 2001 was offset, in part, by reduced revenue on the
products rationalised during 2001 and by reduced revenue from Naprelan and
Ceclor CD. Product sales of rationalised products, which represents revenue
prior to rationalisation, was $101.7 million for 2001, compared to $146.5
million for 2000. Revenue from Naprelan declined by $33.6 million in 2001, from
$41.8 million in 2000 to $8.2 million in 2001, reflecting factors including
competition and less promotional focus by Elan. Revenue from Ceclor CD declined
by $26.0 million in 2001, from $39.4 million in 2000 to $13.4 million in 2001,
reflecting generic competition.

In both 2001 and 2000, Zanaflex accounted for 11% of product revenue. No other
product accounted for more than 10% of product revenue in either 2001 or 2000.

Product Rationalisations

During 2001, Elan reorganised its sales force into five groups, consisting of
primary care, hospital, neurology, specialty/dermatology and clinical sales
consultants. Sales force activity was redirected to promote Zanaflex, Skelaxin,
Abelcet, Azactam, Maxipime, Myobloc, Zonegran and Cutivate. Elan also commenced
a product acquisition and marketing alliance strategy to access brands meeting
certain commercial criteria established by Elan. Conversely, pursuant to its
rationalisation programme, Elan rationalised certain of its products that did
not meet its commercial criteria. This rationalisation programme generated
product revenue and profits for Elan. The commercial criteria on which the
promoted products were chosen, and against which product acquisitions or
marketing alliances were evaluated, included potential future revenue from the
product; whether the product was in a therapeutic area in which Elan marketed
products or had pipeline products; whether the product was a niche product; and
whether Elan's drug delivery technologies could be utilised to enhance the
value of the product. For example, Elan assumed responsibility for the U.S.
marketing rights of Sonata in December 2001 pursuant to its marketing alliance
with Wyeth and acquired the Roxane pain management products from Roxane in
September 2001.

In 2001, Elan rationalised Diastat, Entex, Furadantin, Midrin, Mysoline,
Nasalide, Nasarel and Permax. These rationalisations were accomplished through
outright sales or pursuant to distribution and royalty arrangements. The
rationalised products did not fit with Elan's commercial criteria. Some of
these products would also have suffered over time from the withdrawal of
promotional support by Elan. In certain cases, the products were also facing
other challenges such as the potential for generic competition.

Revenue generated from product rationalisations is recorded as product revenue.
Elan recorded net product revenue of $231.4 million from product
rationalisations in 2001. This is recorded as exceptional product revenue. The
rationalised products generated revenue prior to rationalisation of $101.7
million for 2001, compared to $146.5 million for 2000.

The following table lists each product rationalised in 2001, the Company to
which the product was rationalised and the net revenue recorded by Elan in 2001
from the rationalisation. Net income from product rationalisations in 2001
amounted to $215.8 million.

- ----------------------------------------------------------------------------------------------------


(A) Diastat/Mysoline

Xcel was formed in January 2001. Xcel is a specialty pharmaceutical company
with an initial focus on neurology. Mr Cam Garner, Mr Michael Borer and Mr John
Cook, founders of Xcel, were previously employed by Dura, a company Elan
acquired in November 2000. Mr James Fares, a founder of Xcel, was previously
employed by Elan.

Elan rationalised the product rights and related inventory of Diastat to Xcel
on 31 March 2001. Elan subsequently rationalised the product rights and related
inventory of Mysoline to Xcel. Both these products fall within Xcel's focus on
neurology. Diastat and Mysoline are products used for the treatment of
epilepsy. Under the product agreements, Xcel acquired worldwide rights to
Diastat and exclusive rights to Mysoline in the United States. Elan received
aggregate cash consideration of $160.0 million for Diastat and Mysoline. Elan
also had a royalty right of between 5% and 20% on net sales of Mysoline by
Xcel. After reducing the carrying value of the related intangible assets, Elan
recorded net revenue of $97.0 million and $23.5 million on the rationalisation
of Diastat and Mysoline, respectively, in 2001.

On 30 March 2001, Xcel raised net proceeds of $69.6 million from issuing
convertible preferred stock. Elan purchased $15.0 million of this convertible
preferred stock, representing approximately 16% of Xcel's equity on a fully
diluted basis. On this date, two venture capital funds and their affiliates
purchased 54% of Xcel's equity on a fully diluted basis.

On 31 March 2001, Elan provided a loan of $99.0 million to Xcel. Elan also
provided a $10.0 million line of credit to Xcel, which was drawn down in June
2002.

Mr Erle Mast, who, at the time, was an Elan employee, became a member of Xcel's
board of directors in February 2002.

On 1 April 2003, Elan announced that it received $89.5 million in cash from
Xcel in exchange for all of Elan's shareholding in, and loans to, Xcel. In
addition, the royalty right on net sales of Mysoline was terminated. The net
carrying value of the shares and loan notes was written down during 2002 by
$34.5 million.

(B) Nasarel/Nasalide

IVAX is engaged in the research, development, manufacturing and marketing of
branded and brand equivalent (generic) pharmaceuticals and veterinary products
in the United States and international markets. In September 2001, Elan
rationalised the product rights and related inventory of Nasarel and Nasalide
to IVAX. Elan received cash consideration of approximately $120.0 million for
Nasarel and Nasalide and retained a royalty right of between 5% and 10% on net
sales of Nasarel and Nasalide by IVAX. After reducing the carrying value of the
related intangible assets, Elan recorded net revenue of $62.6 million on the
rationalisation of Nasarel and Nasalide in 2001.

(C) Permax

Amarin is a specialty pharmaceutical company focused on neurology and pain
management. Mr Thomas Lynch, an employee of Elan and formerly its executive
vice chairman, and Mr John Groom, a director of Elan, serve on Amarin's board
of directors. Mr Lynch is non-executive chairman of Amarin. Mr Michael Coffee
and Mr Donald Joseph, both employees of Amarin, were previously employed by
Elan.


- --------------------------------------------------------------------------------

- --------------------------------------------------------------------------------

In May 2001, Elan and Amarin entered into a distribution and option agreement,
whereby Amarin agreed to market and distribute Permax in the United States, and
was granted an option to acquire rights to the product from Elan. Permax is
used for the treatment of Parkinson's disease and falls within Amarin's focus
on neurology. In September 2001, this agreement was amended, whereby Amarin was
appointed the sole distributor of Permax in the United States until August
2002. Elan recorded consideration of $45.0 million under the terms of the
amended distribution and option agreement and retained a royalty right of 3.5%
on net sales of Permax by Amarin from 1 January 2002 through the date on which
Amarin exercised or terminated its option to acquire Permax. In 2001, Elan also
recorded a net amount of $6.2 million from Amarin for distribution fees and
royalties on sales of Permax. After reducing the carrying value of the Permax
intangible and equity accounting, Elan recorded net revenue from Amarin of
$16.9 million in 2001 which includes the distribution revenue. Amarin's option
to purchase Permax was exercisable between September 2001 and May 2002 for an
exercise price of $37.5 million, payable $7.5 million on exercise of the option
and $2.5 million in quarterly instalments thereafter, and a royalty of between
7% and 10% on future net sales of Permax by Amarin. The royalty would have been
reduced or increased by up to $8.0 million if Permax revenues in 2003 and 2004
are less than (for a royalty reduction) or greater than (for a royalty
increase) $26.0 million and $16.0 million, respectively. On 11 March 2002,
Amarin exercised its option to acquire Permax and paid Elan the first
instalment of the exercise price of $7.5 million.

Elan has not recognised the unpaid option exercise price, but rather intends to
record such consideration as it is received due to uncertainties surrounding
its ultimate collectibility. In January 2003, in addition to the amendments
described below, Elan and Amarin agreed to amend certain terms of their
agreements including a reduction of $7.5 million in the total quarterly
deferred option payments due to Elan in 2004 and 2005, incurred in connection
with the acquisition of the Permax rights by Amarin, and the inclusion of
Elan's shares in the registration statement filed for the investors in
connection with the private placement described below. Elan has agreed not to
sell any of those shares until 1 October 2003, with certain exceptions. Further
as described below, Elan and Amarin further amended their agreements in August
2003, such that Amarin may discharge in full its obligations to Elan under the
loans referred to above and its remaining obligations to Elan arising from its
exercise of the Permax option for a payment of $30.0 million.

In connection with the amended distribution and option agreement, Elan provided
a loan of $45.0 million to Amarin. The loan bears interest at a rate equal to
London Interbank Offered Rate ("LIBOR") plus a margin of 2%. The loan
originally matured on 28 September 2002. In July 2002, the maturity date of the
loan was amended to $2.5 million payable in July 2002 (repaid in July 2002),
$17.5 million payable in September 2002, $10.0 million payable in September
2003 and $15.0 million payable in September 2004. In January 2003, $19.9
million of this loan, including interest of $2.4 million, was repaid by Amarin
and the maturity of the remaining amount of the loan was amended to $10.0
million payable in September 2004 and $15.0 million payable in September 2005.
Futher amendments to the agreements with Amarin were entered into during August
2003 and are described below.

During 2001, Elan granted Amarin a purchase option to acquire Zelapar. Zelapar
is a fast melt formulation of selegiline for the treatment of Parkinson's
disease. The purchase option was amended in January 2003, and was exercisable
until 30 days after FDA approval of Zelapar. If Amarin exercised the option
Elan would have received approximately $10 million, and may have additionally
received revenue-contingent milestone payments of up to $32.5 million. Elan
would have also received a royalty of 12.5% on future net sales of Zelapar by
Amarin. Futher amendments to the agreements with Amarin were entered into
during August 2003 and are described below.

In August 2003, Elan and Amarin agreed to further amend certain terms of their
agreements whereby Amarin has until 31 December 2003 to pay $30.0 million to
Elan. If Amarin does so, all loans referred to above and outstanding deferred
payments due in connection with the purchase of Permax will be discharged in
full, and Amarin will be deemed to have exercised its option to acquire
Zelapar. Elan will additionally receive a royalty of 12.5% of net sales of
Zelapar by Amarin, and may receive a future revenue-contingent milestone
payment of $10.0 million in ordinary shares of Amarin if annual sales of
Zelapar exceed $20.0 million. Further, in the event that Amarin raises in
excess of $40.0 million from financings or specified asset sales by 30 June
2004, Amarin will be obliged to apply half the excess, up to a maximum of $10.0
million, to reduce the rate of the royalty on net sales. The royalty rate will
be reduced by 0.5% of net sales for each $1.0 million paid to Elan. If Amarin
does not pay Elan $30.0 million by 31 December 2003, then all such debts and
deferred payments will become due and payable on demand by Elan and the Zelapar
option will be deemed cancelled and non-exercisable. In that event, Elan will
additionally be entitled at its option to convert all amounts owed to the Group
by Amarin into ordinary shares of Amarin at any time. The amounts owed will be
converted into Amarin ordinary shares at a price equivalent to the average
closing price per Amarin share for the five days prior to the date that the
option to convert is exercised. Amarin granted to Elan fixed and floating
security over its assets and business to secure payments due to Elan. This
security will be reduced to $5.0 million in the event that Amarin pays the
$30.0 million amount referred to above by 31 December 2003. The royalty
increase or decrease for Permax based on sales in 2003 and 2004 was eliminated.
Amarin is entitled to redeem the Permax royalty at any time by paying $700,000
to Elan. All quarterly payments due in connection with the purchase of Permax
and all loan interest payments due are subject to a moratorium that expires on
31 December 2003.

ELAN CORPORATION, PLC 2002 ANNUAL REPORT AND FORM 20-F                      45


FINANCIAL REVIEW
- --------------------------------------------------------------------------------

At 31 December 2002, Elan held approximately 27% of the outstanding ordinary
shares of Amarin and also held preferred shares convertible into,
approximately, an additional 12% of Amarin's equity on a fully diluted basis.
On 28 January 2003, Amarin announced the completion of a private placement for
gross proceeds of $21.2 million. In connection with this transaction Elan also
converted 2,000,000 Amarin convertible preference shares into ordinary shares.
As a result of these transactions, Elan's share ownership in Amarin is
approximately 26% on a fully diluted basis.

Under Irish GAAP Elan accounted for Amarin using the equity method, based on
Elan's fully diluted equity investment in Amarin in 2001 and 2002. Amarin is a
related party to Elan. Elan recorded net revenue from Amarin of $4.8 million in
2002 (2001: $16.9 million). Elan's total investment in Amarin at 31 December
2002 amounted to $63.2 million, consisting of loans, including interest, of
$44.8 million and $6.5 million and a net equity investment of $11.9 million. As
described above, Amarin repaid $17.5 million of this loan and interest of $2.4
million in January 2003. In addition, Elan has trading balances due from Amarin
of $13.7 million at 31 December, 2002 (2001:$Nil).

Amarin's financial position at 31 December 2002 was as follows: current assets
Sterling29.6 million (2001: Sterling28.6 million), non-current assets
Sterling31.0 million (2001: Sterling33.9 million), current liabilities
Sterling41.6 million (2001: Sterling36.9 million) and non-current liabilities
Sterling22.8 million (2001: Sterling5.2 million).

Amarin's results of operations for the year ended 31 December 2002 were as
follows: turnover Sterling40.6 million (2001: Sterling39.2 million), gross
profit Sterling22.0 million (2001: Sterling23.4 million), operating loss from
continuing operations Sterling20.3 million (2001: Sterling3.5 million) and loss
for the financial year Sterling23.0 million (2001: Sterling3.3 million).

(D) Other Product Rationalisations

In June 2001, Elan rationalised the product rights and related inventory of
Entex to Andrx. Andrx is a corporation that commercialises controlled-release
oral pharmaceuticals using its proprietary drug delivery technologies. Elan
received cash consideration of $14.7 million and retained a royalty of 10% on
sales of Entex for 10 years from 2002. If annual sales of Entex exceed $10.0
million, Andrx will make additional royalty payments to Elan of 5% on sales in
excess of $8.0 million. Elan recorded net revenue of $12.8 million on the
rationalisation of Entex in 2001. The royalties are subject to a cap of $0.8
million per annum if Andrx reformulates the product.

In June 2001, Elan rationalised the product rights and related inventory of
Midrin to WFHC. WFHC is a specialty pharmaceutical company dedicated to
improving the health and well-being of midlife women. Elan received cash
consideration of $15.0 million and retained a royalty right of 10% on net sales
of Midrin by WFHC for 10 years from 2002. Elan recorded net revenue of $13.6
million on the rationalisation of Midrin in 2001. The maximum annual royalty
receivable is $0.5 million from 2003. Elan provided a loan to WFHC in the form
of an $11.0 million convertible promissory note. Elan will earn interest on the
note at a rate of 7% per annum. The note matures in June 2008. In addition,
Elan purchased 400,000 shares of WFHC common stock for $4.0 million.

In December 2001, Elan rationalised the product rights and related inventory of
Furadantin to First Horizon for cash consideration of $16.0 million. First
Horizon is a specialty pharmaceutical company that markets and sells brand name
prescription products. After reducing the carrying value of the Furadantin
intangible, Elan recorded net revenue of $11.2 million on the rationalisation
of Furadantin in 2001.

Contract Revenue

Contract revenue decreased by 30% to $333.7 million for 2001 from $476.4
million for 2000, primarily reflecting a reduction in licence fees of $219.4
million mainly due to fewer new business venture agreements entered into during
2001, offset, in part, by an increase in research revenue of $45.6 million.
Aggregate contract revenue from Pharma Marketing and Autoimmune increased by
113% to $58.7 million in 2001 from $27.6 million in 2000.

Fee revenue from the business venture programme decreased by 46% to $172.5
million for 2001, compared to $321.2 million for 2000. Research revenue from
the business venture programme was $15.0 million and $15.4 million in 2001 and
2000, respectively.

Major Customers

Cardinal Health and Pharma Marketing accounted for approximately 14% and 11%,
respectively, of Elan's total revenue for 2001. No other customer accounted for
more than 10% of revenue in 2001. No customer accounted for more than 10% of
revenue in 2000.

COST OF SALES

Cost of sales, after exceptional items, increased by 23% to $386.8 million for
2001 from $315.5 million for 2000. The increase was 33% before exceptional
items of $22.8 million in 2001 and $42.0 million in 2000. The increase, before
exceptional items, primarily reflects the


- --------------------------------------------------------------------------------
46


- --------------------------------------------------------------------------------

inclusion in 2001 of a full year's product cost of sales from the acquisitions
of Dura and Liposome and the increased sales volume on other products such as
Zanaflex and Skelaxin. The gross margin on total revenue, before exceptional
items, was approximately 76% for 2001 and 79% for 2000. Gross margin on total
revenue, after exceptional items, was 78% in 2001 and 76% in 2000. Gross margin
on product revenue, before exceptional items, increased to 69% in 2001 from 67%
in 2000, primarily reflecting higher revenue from directly marketed products
with above average gross margins such as Zanaflex, Skelaxin, Maxipime and
Abelcet.

SELLING, GENERAL AND ADMINISTRATIVE EXPENSES

Selling, general and administrative expenses, after exceptional items,
increased by 363% to $1,781.7 million for 2001 from $384.9 million for 2000.
The increase was 84% before exceptional items of $1,084.2  million in 2001 and
$5.3 million in 2000. The increase, before exceptional items, primarily
reflects the inclusion of Dura and Liposome for a full year in 2001 (including
a full year's amortisation charges for the related goodwill and intangibles),
the expansion of Elan's existing U.S. activities and the building of Elan's
European infrastructure. The increases in selling, general and administrative
expenses in 2001 that arose from the inclusion of Dura for a full year, the
inclusion of Liposome for a full year, the expansion of Elan's existing U.S.
activities and the building of Elan's European infrastructure were $167.3
million, $26.9 million, $55.2 million and $19.2 million, respectively.

RESEARCH AND DEVELOPMENT EXPENSES

Research and development expenses, after exceptional items, increased by 32% to
$401.9 million for 2001 from $305.3 million for 2000. The increase was 18%
before exceptional items of $78.6 million in 2001 and $32.0 million in 2000.
The increase, before exceptional items, primarily reflects a higher level of
research and development activities in Core Elan, principally for Antegren,
AN-1792 and Myobloc, and in Elan Enterprises.

EXCEPTIONAL ITEMS

In 2001, Elan incurred net exceptional charges of $964.6 million.

Exceptional revenue in 2001 primarily relates to product rationalisation
revenue of $231.4 million. The exceptional cost of sales related to product
rationalisation revenue was $15.6 million.

Exceptional selling, general and administrative expenses were $1,084.2 million
in 2001. $1,009.8 million of the exceptional charges relate to impairment
charges arising on write-downs of intangible assets. Impairment charges to
acquired IP arising from the acquisitions of Neurex and Sano were $500.0
million and $285.2 million, respectively. Impairment charges to patents and
licences arising on write-downs of the product intangibles for Naprelan, Ceclor
CD and Myambutol were $81.0 million, $94.2 million and $44.4 million,
respectively. Other impairments to patents and licences amounted to $5.0
million.

Elan acquired Neurex in August 1998 for $810.0 million. Neurex was developing
Prialt. The purchase price was primarily allocated to acquired IP. In 2001,
Elan wrote down acquired IP arising from the acquisition of Neurex by $500.0
million. This write-down was due to delays in the product launch schedule and
reduced revenue projections for Prialt.

Elan acquired Sano in February 1998 for $434.6 million. Sano was developing
transdermal drug delivery products. The purchase price was primarily allocated
to acquired IP. In 2001, Elan wrote down acquired IP arising from the
acquisition of Sano by $285.2 million. The write-down was due to reduced
revenue projections from products under development and to Elan's decision to
focus its research and development efforts in other areas.

Ceclor CD and Myambutol were written down due to the impact of generic
competition on these products during 2001. Generic versions of each of these
products were approved and launched in 2001, which has reduced projected
revenues and profitability from these products. Revenue from Ceclor CD declined
by $26.0 million in 2001, from $39.4 million in 2000 to $13.4 million in 2001.
Naprelan was written down due to lower than forecast revenues in 2001 and
reduced projected revenue and profitability from this product. The level of
promotional support for a product can have a significant impact on the level of
revenue generated from that product. Elan does not expect to provide any
significant promotional support for Naprelan in the future and this has been
reflected in the projections for this product. Revenue from Naprelan declined
by $33.6 million in 2001, from $41.8 million in 2000 to $8.2 million in 2001.

Other exceptional selling, general and administrative expenses were $74.4
million. These primarily relate to severance, integration, relocation and
similar costs and asset write-downs arising from the integration of Elan's U.S.
Biopharmaceuticals business.

ELAN CORPORATION, PLC 2002 ANNUAL REPORT AND FORM 20-F                      47


FINANCIAL REVIEW
- --------------------------------------------------------------------------------

Exceptional research and development expenses were $78.6 million in 2001. These
mainly relate to severance, integration and similar costs and asset write-downs
arising from the re-organisation, closure or scaling back of various drug
delivery programmes and sites. Also included were costs of certain research
programmes that Elan does not intend to complete. These were the estimated
costs incurred pending closure or sale.

Exceptional net interest and other expenses were $6.8 million in 2001. These
mainly relate to costs associated with the redemption in March 2001 of the
4.75% Exchangeable Notes issued by Athena Neurosciences.

In 2000, Elan incurred exceptional charges of $113.6 million. In November 2000,
the FDA requested that the pharmaceutical industry voluntarily cease the
distribution and marketing of products containing phenylpropanolamine ("PPA").
The Company ceased shipment of the products containing PPA and withdrew them
from customers' warehouses and retail shelves. In connection with the
termination of this activity, Elan incurred an exceptional charge of $35.6
million, primarily for product returns and the write-off of inventory and
product intangible assets. Elan incurred charges of $0.6 million arising from
the acquisition of Dura. Elan incurred charges of $10.4 million arising from
the termination of certain research and development projects and charges of
$21.4 million relating to the write-down of certain intangible assets arising
from a change in focus of Elan's business. Elan incurred charges of $22.2
million arising from a rationalisation of its Biopharmaceuticals business unit,
primarily relating to severance costs and the transfer of most pharmaceutical
distribution activities and certain inventory to one location in the United
States, resulting in exceptional inventory write-offs. The remaining
exceptional charges primarily related to asset write-downs.

For additional information regarding exceptional charges, please refer to Note
3 to the Consolidated Financial Statements.

NET INTEREST AND OTHER (EXPENSE)/INCOME

Net interest and other expense was $50.4 million for 2001 as compared with net
interest and other income of $88.6 million for 2000. Interest payable and
similar charges increased by 110% to $291.9 million for 2001 from $138.8
million for 2000, primarily reflecting interest payable of $40.3 million on the
7.25% Senior Notes, interest payable of $35.4 million on the EPIL III Notes
issued in March 2001, an increase of $21.1 million due to the inclusion for
2001 of a full year of interest payable on the EPIL II Notes issued in June
2000 and increased financing and other fees. Elan expenses the subsequent
funding it provides directly to business ventures. This is expensed within the
interest and other expense line. Elan expensed $24.6 million and $10.0 million
for this subsequent funding, in 2001 and 2000, respectively. Income from
financial assets increased by 6% to $241.5 million for 2001 from $227.4 million
for 2000. Interest and other income increased to $159.2 million for 2001 from
$112.5 million in 2000. Gains on financial assets decreased to $80.5 million in
2001 from $109.3 million in 2000. Gains on financial assets in 2001 includes
$31.5 million for the sale of approximately 20% of Athena Diagnostics in
December 2001. Foreign exchange gains amounted to $1.8 million in 2001 and $5.6
million in 2000.

For additional information regarding net interest and other expense, please
refer to Note 5 to the Consolidated Financial Statements.

For additional information regarding indebtedness, please refer to Note 16 to
the Consolidated Financial Statements and to "Debt Facilities" in this
Financial Review.

TAXATION

Tax on profit on ordinary activities increased by 93% to $17.4 million for 2001
from $9.0 million for 2000. The tax charges reflected tax at standard rates in
the jurisdictions in which Elan operates, income derived from Irish patents
which is exempt from tax, foreign withholding tax and the availability of tax
losses. Elan's Irish patent derived income was exempt from taxation pursuant to
Irish legislation, which exempts from Irish taxation income derived from
qualifying patents. Currently, there is no termination date in effect for such
exemption.

For additional information regarding taxation, please refer to Note 8 to the
Consolidated Financial Statements.

RETAINED (LOSS)/PROFIT

After exceptional items, retained (loss)/profit for the year decreased to a
retained loss of $887.2 million for 2001 from a retained profit of $342.1
million for 2000. Retained profit for the year, before exceptional items,
decreased by 83% to $77.4 million for 2001 from $455.7 million for 2000. Basic
loss per share, after exceptional items, was $2.64 for 2001, compared to basic
earnings per share of $1.19 for 2000. Basic earnings per share, before
exceptional items, decreased by 86% to $0.23 for 2001 from $1.59 for 2000. The
percentage


- --------------------------------------------------------------------------------

- --------------------------------------------------------------------------------

decrease in basic earnings per share, before exceptional items, was greater
than the percentage decrease in retained profit, before exceptional items,
primarily due to the higher number of Elan's ordinary shares (the "Ordinary
Shares") in issue. Elan issued an aggregate of approximately 18 million
Ordinary Shares for the exercise of warrants and options during 2001, including
approximately 10 million Ordinary Shares on the exercise of the Series A
warrants issued by Axogen. Elan also issued approximately 9 million Ordinary
Shares in exchange for the 4.75% Exchangeable Notes issued by Athena
Neurosciences in November 1997, which were redeemed in March 2001. Diluted loss
per share, after exceptional items, was $2.64 for 2001, compared to diluted
earnings per share of $1.10 for 2000. Diluted earnings per share, before
exceptional items, decreased by 85% to $0.22 for 2001 from $1.46 for 2000.

RISK-SHARING ARRANGEMENTS

PHARMA MARKETING

In June 2000, Elan disposed of royalty rights on certain products and
development projects to Pharma Marketing. Pharma Marketing completed a private
placement of its common shares to a group of institutional investors, resulting
in gross proceeds of $275.0 million. Elan holds no investment in Pharma
Marketing and has no representative on its board of directors. Concurrent with
the private placement, Pharma Marketing entered into a Program Agreement with
Elan. The Program Agreement, which substantially regulates the relationship
between Elan and Pharma Marketing, represents a risk-sharing arrangement
between Elan and Pharma Marketing. Under the terms of the Program Agreement,
Pharma Marketing acquired certain royalty rights to each of the following
products for the designated indications (including any other product which
contains the active ingredient included in such product for any other
designation): (i) Frova, for the treatment of migraine; (ii) Myobloc, for the
treatment of cervical dystonia; (iii) Prialt, for the treatment of acute pain
and severe chronic pain; (iv) Zanaflex, for the treatment of spasticity and
painful spasm; and (v) Zonegran, for the treatment of epilepsy. Pharma
Marketing agreed to make payments to Elan in amounts equal to expenditures made
by Elan in connection with the commercialisation and development of these
products, subject to certain limitations. These payments were made on a
quarterly basis based on the actual costs incurred by Elan. Elan did not
receive a margin on these payments.

Elan's revenue from Pharma Marketing was $31.3 million for 2002, consisting of
$24.0 million for commercialisation expenditures, which has been recorded as
product revenue, and $7.3 million for development expenditures, which has been
recorded as contract revenue. Pursuant to the Program Agreement, Pharma
Marketing utilised all of its available funding by mid-2002. Elan will not
receive any future revenue from Pharma Marketing. Elan's revenue from Pharma
Marketing was $189.8 million for 2001, consisting of $141.8 million for
commercialisation expenditures and $48.0 million for development expenditures.
In 2002, the royalty rate on net sales of all designated products was 15.79% on
the first $122.9 million of net sales and 3.51% for net sales above $122.9
million. Elan paid aggregate royalties of $24.1 million for 2002. This was
recorded as a cost of sales. In 2001, the royalty rate on net sales of Zanaflex
was 8.44% on the first $38.0 million of net sales and 1.88% for net sales of
Zanaflex above $38.0 million. No royalties were payable on the other products
in 2001. Elan paid aggregate royalties of $5.6 million for 2001.

In December 2001, the Program Agreement was amended such that Elan re-acquired
the royalty rights to Myobloc and disposed of royalty rights on Sonata to
Pharma Marketing. The amendment was transacted at estimated fair value. The
board of directors and shareholders of Pharma Marketing approved this
amendment. The estimated difference in relative fair value between the royalty
rights on Sonata and the royalty rights on Myobloc was $60.0 million. This
amount was paid to Pharma Marketing by Elan in cash and was capitalised by Elan
as an intangible asset.

Under the original agreements, Elan could have, at its option at any time prior
to 30 June 2003, acquired the royalty rights by initiating an auction process.
This date was extended to 3 January 2005 under the settlement with Pharma
Marketing and Pharma Operating described below. In addition, the holders of
Pharma Marketing common shares may initiate the auction process earlier upon
the occurrence of certain events. Pursuant to the auction process, the parties
will negotiate in good faith to agree on a purchase price, subject to Elan's
right to re-acquire the royalty rights at a maximum purchase price. The maximum
purchase price was approximately $413 million at 31 December 2002 and increased
by approximately 25% annually (less royalty payments). The purchase price was
reduced under the settlement with Pharma Marketing and Pharma Operating
described below. If the parties are unable to agree on a purchase price and
Elan elects not to exercise its right to re-acquire the royalty rights at the
maximum purchase price, or if Elan elects not to initiate the auction process
prior to the option termination date, Pharma Marketing can dispose of the
royalty rights in an auction to the highest bidder or retain the royalty
rights. If Elan does not acquire the royalty rights, the royalty rates increase
annually up to a maximum blended effective royalty rate of 52.5% on aggregate
net sales of the products by 2005.

On 17 January 2003, Elan announced that Pharma Operating had filed a lawsuit in
the Supreme Court of the State of New York against Elan and certain of its
subsidiaries in connection with the risk-sharing arrangement between the
parties. The lawsuit sought, among

FINANCIAL REVIEW
- --------------------------------------------------------------------------------

other things, a court determination that Pharma Operating's approval would be
required in the event of a sale by Elan of its interest in Sonata to a third
party. On 30 January 2003, Elan, Pharma Operating and its parent Pharma
Marketing, agreed to settle the lawsuit and, under the terms of the settlement
agreement, Pharma Operating dismissed the litigation between the parties
without prejudice. Pursuant to the settlement agreement, effective upon the
sale of Sonata to King on 12 June 2003, (i) Elan paid Pharma Operating $196.4
million in cash (representing $225.0 million less royalty payments on all
related products paid or due to Pharma Operating from 1 January 2003 through 12
June 2003) to acquire Pharma Operating's royalty rights with respect to Sonata
and Prialt and (ii) Elan's maximum purchase price for the remaining products in
the arrangement, Zonegran, Frova and Zanaflex, was reduced to $110.0 million,
which will increase at a rate of 15% per annum from 12 June 2003 (less royalty
payments made for periods after 12 June 2003). The parties also agreed to
extend Elan's purchase option termination date to 3 January 2005 from the
original termination date of 30 June 2003.

In connection with the settlement agreement, Elan agreed that it would cause
certain subsidiaries in the United States, Ireland, the United Kingdom,
Germany, France, Spain and Italy to pledge their accounts receivable from
commercial sales of pharmaceutical products and services to Pharma Operating as
collateral to secure Elan's obligations in relation to royalty payments under
the Pharma Marketing arrangement and the settlement agreement. Elan also agreed
that, following the closing of a sale of Sonata, it would grant Pharma
Operating additional collateral to the extent that the aggregate value of the
collateral package, which is to be tested on a quarterly basis, is less than
the maximum purchase price for the royalty rights on Zonegran, Frova and
Zanaflex. On 6 March 2003, Elan Pharmaceuticals, Inc. ("EPI") and Pharma
Operating entered into a security agreement pursuant to which EPI granted
Pharma Operating a first priority security interest in its accounts receivable
from commercial sales of pharmaceutical products in the United States. On that
same date, Elan and Pharma Operating agreed to the terms of the additional
collateral mechanism. On 20 May 2003, Elan Pharma Limited ("EPL") and Pharma
Operating entered into a security agreement pursuant to which EPL granted
Pharma Operating a security interest in its accounts receivable from commercial
sales of pharmaceutical products and services in the United Kingdom. A similar
agreement was entered into in relation to Ireland by Elan Pharma Limited
(Ireland) on 10 June 2003. Negotiations have not begun for Germany, France,
Spain or Italy. The parties have agreed that each of the security agreements
will provide for the release of Pharma Operating's lien on any accounts
receivable of a product or service in which Elan disposes of all or a
substantial portion of its rights. Accordingly, Elan does not expect that any
of the security arrangements with Pharma Operating will limit Elan's ability to
dispose of assets in connection with the recovery plan.

AUTOIMMUNE

In December 2001, Autoimmune, in an initial tranche, completed a private
placement of its common shares to a group of institutional investors, resulting
in gross proceeds to Autoimmune of $95.0 million. In the same initial tranche,
Elan purchased non-voting preferred shares of Autoimmune's subsidiary for an
aggregate purchase price of $37.5 million. Elan had no representative on the
board of directors of Autoimmune. The existing group of institutional investors
and Elan also committed to a second investment tranche in the same amounts to
be completed in April 2003, subject to certain conditions. Autoimmune entered
into a Program Agreement with Elan. The Program Agreement, which substantially
regulated the relationship between Elan and Autoimmune, represented a
risk-sharing arrangement among the companies. Under the terms of the Program
Agreement, Autoimmune acquired royalty rights to each of the following products
and development projects for the designated indications: (i) Antegren, for the
treatment of relapsing forms of MS, moderate-to-severe inflammatory bowel
disease, including Crohn's disease and ulcerative colitis, and
moderate-to-severe rheumatoid arthritis; (ii) Maxipime, for the treatment of
infection; (iii) Azactam, for the treatment of infection; and (iv) Abelcet, for
the treatment of severe fungal infection. Autoimmune also acquired royalty
rights on certain development projects, as well as any other product
subsequently developed or acquired by Elan that had an indication substantially
the same as Maxipime, Azactam or Abelcet and that would be in direct
competition with Maxipime, Azactam or Abelcet. Autoimmune agreed to make
payments to Elan in amounts equal to expenditures made by Elan in connection
with the commercialisation and development of these products, subject to
certain limitations. These payments were to be made on a quarterly basis based
on actual costs incurred by Elan. Elan did not receive a margin on these
payments. Elan's revenue from Autoimmune was $68.7 million for 2002, consisting
of $38.8 million for commercialisation expenditures, which has been recorded as
product revenue, and $29.9 million for development expenditures, which has been
recorded as contract revenue. Elan's revenue from Autoimmune was $26.6 million
for 2001, consisting of $15.9 million for commercialisation expenditures, and
$10.7 million for development expenditures. Elan received no revenue from
Autoimmune since June 2002. Elan will not receive any future revenue from
Autoimmune. No royalties were payable to Autoimmune by Elan in either 2002 or
2001.



Under the original agreement, Elan could, at its option at any time prior to
April 2005, acquire the royalty rights by initiating an auction process. In
addition, the holders of the Autoimmune common shares could initiate the
auction process earlier upon the occurrence of certain events. If the auction
process had not been initiated prior to October 2004, it would have
automatically commenced. Pursuant to the auction process, Elan and Autoimmune
would have negotiated in good faith to agree on a purchase price, subject to
Elan's right to re-acquire the royalty rights at a maximum purchase price. This
maximum purchase price increased at various rates, approximately 25% annually,
subject to certain conditions.


- --------------------------------------------------------------------------------
50


- --------------------------------------------------------------------------------

In July 2002, Elan announced the termination of all agreements relating to the
risk-sharing arrangement with Autoimmune. The royalty obligations to Autoimmune
were terminated. The total consideration for the royalty rights was $121.0
million which, after taking account of the redemption of Elan's investment of
$38.5 million in Autoimmune, resulted in a net cash cost of $82.5 million. Elan
expensed $121.0 million as an exceptional selling, general and administrative
expense arising from the acquisition of Autoimmune.

CAPITALISATION AND LIQUIDITY

Elan had net debt of $1,295.8 million at 31 December 2002, consisting of
outstanding debt of $2,382.3 million, less cash and liquid resources, excluding
managed funds, of $1,086.5 million. For additional information regarding Elan's

cash expended to acquire tangible and intangible fixed assets of $467.7 million
(2001: $394.3 million), a payment of $121.0 million made to acquire product
royalty rights held by Autoimmune and $38.5 million received on disposal of an
investment in Autoimmune and net cash expended to acquire financial assets of
$71.7 million (2001: $553.0 million). Also included was a net cash inflow of
$6.4 million from the sale of EPIL III investments in connection with the

Cash paid for acquisitions was $Nil in 2002, compared to $9.5 million in 2001.
Cash of $361.3 million was received in 2002 primarily from the disposal of the
Abelcet business. Cash received for the disposal of the remaining holding in
Athena Diagnostics (approximately 80%) was $81.8 million; approximately 20% of
Athena Diagnostics was disposed in 2001 for $41.9 million.

Elan's initial investment in business ventures and business venture parents,
arising from the formation of business ventures, was $Nil and $229.2 million in
2002 and 2001, respectively. Elan invested $83.4 million and $92.2 million in
2002 and 2001, respectively, in business venture parents, apart from such
initial investment.

During 2002, Elan had cash outflows from financing activities of $681.1
million, primarily reflecting an outflow of $325.0 million for the repayment of
borrowings under the revolving credit facility, a cash outflow of $160.0
million in connection with the maturity of the EPIL III Series A Guaranteed
Notes, and repayment of the 3.5% Convertible Notes in the amount of $62.6
million. In December 2002, Elan repurchased approximately 19% of the LYONs for
$149.8 million. This is included in the Consolidated Statement of Cash Flows as
$126.9 million within financing activities and $22.9 million within returns on
investments and servicing of finance.

During 2001, Elan had cash inflows from financing activities of $1,277.6
million, primarily reflecting proceeds of $650.0 million from the issuance of
the 7.25% Senior Notes and $550.0 million from the issuance of the EPIL III
Notes, net proceeds of $125.0 million from additional borrowings under Elan's
revolving credit facility and proceeds of $304.8 million from the issuance of
share capital, offset, in part, by the repayment of the 8.43% guaranteed senior
notes due June 2002 (the "8.43% Guaranteed Notes") in the amount of $350.0
million.

CASH, LIQUID RESOURCES AND FINANCIAL ASSETS

Cash and liquid resources amounted to $1,086.5 million at 31 December 2002.

FINANCIAL REVIEW
- --------------------------------------------------------------------------------

o   LYONs due 2018--$792.3 million (accreted value at 31 December 2002);

Holders of the LYONs may require Elan to purchase all or any portion of their
LYONs on 14 December 2003, 14 December 2008 and 14 December 2013 at a purchase
price equal to the issue price plus all accrued original issue discount up to
the purchase date. Elan may, at its option, elect to pay the purchase price for
the LYONs in cash, by the delivery of American Depositary Shares ("ADSs")
representing Ordinary Shares, at the then existing market price, or any
combination of cash and ADSs. Elan's right to pay the purchase price for the
LYONs by delivering ADSs is subject to certain conditions, including the
registration of the ADSs to be delivered under the Securities Act of 1933 and
the listing of those ADSs on the New York Stock Exchange ("NYSE"). In addition,
under the Companies (Amendment) Act, 1983, and a related shareholder resolution
passed on 18 March 2003, the number of ADSs that Elan may issue in payment for
the LYONs will be limited to a maximum of 120 million ADSs unless Elan seeks
and receives an additional resolution from its shareholders authorising it to
issue additional ADSs.

In December 2002, Elan repurchased $318.6 million in principal amount at
maturity of LYONs (representing approximately 19% of the originally issued
LYONs) in separate privately negotiated purchases. These LYONs, having an
accreted value of $190.1 million at the dates of acquisition, were purchased at
an aggregate cost of $149.8 million, resulting in a net gain of $37.7 million
after related costs at the dates of acquisition. This was a discount of
approximately 24% to the accreted value of such LYONs at 14 December 2003 of
$196.5 million.

Through 3 June 2003, Elan repurchased an additional $523.7 million in principal
amount at maturity of the LYONs (representing approximately 32% of the
originally issued LYONs) in separate privately negotiated purchases. The
aggregate cost was $310.3 million. This was a discount of approximately 4% to
the accreted value of such LYONs at 14 December 2003 of $322.9 million. After
taking account of all repurchases up to 3 June 2003, the remaining LYONs have
an accreted value at 14 December 2003 of $494.0 million. Elan may purchase
additional LYONs in the future and any such purchases may be material. For
additional information on the LYONs, please refer to Note 16 to the
Consolidated Financial Statements.

At 31 December 2002, Elan had the following principal amounts outstanding under
other borrowing facilities:

o  EPIL II Notes Due 2004                         --  $450.0 million;
o  EPIL III Notes Due 2005                        --  $390.0 million; and
o  Athena Finance 7.25% Senior Notes Due 2008     --  $650.0 million.

For additional information regarding Elan's outstanding debt, please refer to
Note 16 to the Consolidated Financial Statements.

PRODUCT ACQUISITIONS AND ALLIANCES

At 31 December 2002, Elan included in creditors $482.2 million relating to
future payments and/or future potential payments on products. Of the $482.2
million, $227.2 million is owing at 31 December 2002 and $255.0 million is
potentially payable, contingent on future events. Elan is a party to certain
product acquisition or alliance agreements that have staged or option payments
which may be uncertain in amount, which may be paid at Elan's discretion, such
as upon the exercise of an option to acquire the product, or which must be paid
upon the occurrence of future events, such as the attainment of pre-determined
product revenue targets or other milestones. Elan has accrued $277.6 million
within creditors (within one year), including $130.7 million for
Maxipime/Azactam, $114.7 million for Sonata and $28.3 million for the Pain
Portfolio, and $204.6 million within creditors (after one year), including
$146.0 million for Sonata and $49.1 million for the Pain Portfolio.

At 31 December 2001, Elan included in creditors $900.4 million relating to
future payments and future potential payments on products. The reduction of
$418.2 million from December 2001 to December 2002 primarily reflects product
payments made during the year of $234.6 million and contingent product payments
avoided of $224.3 million. The contingent product payments avoided relate
primarily to Elan's decision not to exercise its option to acquire the
dermatology products from GSK during 2002.

For additional information regarding future payments and potential future
payments on the acquisition of products, please refer to Note 17 to the
Consolidated Financial Statements.

COMMITMENTS AND CONTINGENCIES

On 30 January 2003, Elan, Pharma Operating and its parent, Pharma Marketing,
agreed to settle the pending lawsuit and, under the terms of the settlement
agreement, effective upon the sale of Sonata to King on 12 June 2003, (i) Elan
paid Pharma Operating $196.4


- --------------------------------------------------------------------------------

- --------------------------------------------------------------------------------

million in cash (representing $225.0 million less royalty payments on all
related products paid or due to Pharma Operating from 1 January 2003 through 12
June 2003) to acquire Pharma Operating's royalty rights with respect to Sonata
and Prialt and (ii) Elan's maximum purchase price for the remaining products in
the arrangement, Zonegran, Frova and Zanaflex, was reduced to $110.0 million,
which will increase at a rate of 15% per annum from 12 June 2003 (less royalty
payments made for periods after 12 June 2003).

At 31 December 2002, Elan had commitments to invest $3.2 million in healthcare
managed funds, compared to $25.6 million in 2001.

The Company has deferred purchase arrangements for certain products, which
amount to $4.5 million (2001: $24.5 million). These payments are dependent on
various approvals and milestones being met.

For additional information regarding commitments and contingencies, including
those related to Autoimmune, Pharma Marketing, lease commitments, capital
expenditures, litigation and asset divestitures, please refer to Note 24 and
Note 25 to the Consolidated Financial Statements.

LIQUIDITY

The following table sets out, at 31 December 2002, the main contractual and
potential future payments due by period for debt repayments, contractual and
potential product acquisition and alliance payments and the potential payments
relating to the purchase of royalty rights from Pharma Marketing, after giving
effect to the restructuring of the risk-sharing arrangement with Pharma
Marketing in January 2003 as described below. These represent the major
contractual and potential future payments that may be made by Elan. The table
does not include items such as expected capital expenditures on plant and
equipment, lease payments or future investments in financial assets such as
investments in business ventures.

The LYONs have been included in contractual fixed future payments for 2003.
Holders of the LYONs may require Elan to purchase all or a portion of their
LYONs on 14 December 2003, 14 December 2008 and 14 December 2013 at a purchase
price equal to the issue price plus all accrued original issue discount up to
the purchase date. The maturity date for the LYONs is 2018. As the LYONs are
exchangeable by the holders into ADSs representing Ordinary Shares, the
probability of holders requiring Elan to purchase all or a portion of their
LYONs on 14 December 2003 is dependent upon the trading price of Elan's ADSs on
that date. If such price does not increase sufficiently prior to 14 December
2003 or if Elan does not amend, subject to the acceptance of such amendment by
the holders of the LYONs, the terms of the LYONs, the holders of the LYONs are
likely to require Elan to repurchase their LYONs. In that event, Elan may, at
its option, elect to pay the purchase price for the LYONs in cash, by the
delivery of ADSs representing Ordinary Shares, at the then existing market
price, or any combination of cash and ADSs. Elan's right to pay the purchase
price for the LYONs by delivering ADSs is subject to certain conditions,
including the registration of the ADSs to be delivered under the Securities Act
of 1933 and the listing of those ADSs on the NYSE. In addition, under the
Companies (Amendment) Act, 1983, and a related shareholder resolution passed on
18 March 2003, the number of ADSs that Elan may issue in payment for the LYONs
will be limited to a maximum of 120.0 million ADSs unless Elan seeks and
receives an additional resolution from its shareholders authorising it to issue
additional ADSs.

Through 3 June 2003, Elan repurchased an additional $523.7 million in principal
amount at maturity of the LYONs (representing approximately 32% of the
originally issued LYONs) in separate privately negotiated purchases. The
aggregate cost was $310.3 million.

FINANCIAL REVIEW
- --------------------------------------------------------------------------------

This was a discount of approximately 4% to the accreted value of such LYONs at
14 December 2003 of $322.9 million. After taking account of all repurchases up
to 3 June 2003 the remaining LYONs have an accreted value at 14 December 2003
of $494.0 million.

The table above includes potential future payments of $225.0 million falling
due within one year and $110.0 million falling due after one year relating to
risk-sharing arrangements with Pharma Marketing. On 30 January 2003, Elan
announced that it had agreed with Pharma Marketing and Pharma Operating to
settle their then pending lawsuit and, under the terms of the settlement
agreement, effective upon the sale of Sonata to King on 12 June 2003, (i) Elan
paid Pharma Operating $196.4 million in cash (representing $225.0 million less
royalty payments on all related products paid or due to Pharma Operating from 1
January 2003 through 12 June 2003) to acquire Pharma Operating's royalty rights
with respect to Sonata and Prialt and (ii) Elan's maximum purchase price for
the remaining products in the arrangement, Zonegran, Frova and Zanaflex, was
reduced to $110.0 million, which will increase at a rate of 15% per annum from
12 June 2003 (less royalty payments made for the periods after 12 June 2003).

During 2002, the two major rating agencies covering Elan's debt downgraded
Elan's debt rating. Both rating agencies rate Elan's debt as sub-investment
grade debt. None of Elan's debt has a rating trigger that would accelerate the
repayment date upon a change in rating.

Elan's current debt ratings are as follows:

The agreements governing certain of Elan's outstanding indebtedness contain
various restrictive covenants that restrict the Group's ability to, among other
things, incur additional indebtedness (including intercompany indebtedness),
create liens and other encumbrances, enter into transactions with related
parties, sell or otherwise dispose of assets and merge or consolidate with
another entity. In addition, some of these agreements require Elan to maintain
certain financial ratios. Elan does not currently, and does not expect in the
foreseeable future to have the ability to incur any additional indebtedness
under certain of these covenants. This inability to incur additional
indebtedness (including intercompany indebtedness), together with certain other
events, such as the class action and derivative litigations and the SEC
investigation pending against Elan, the decline in price of Elan's shares and
the downgrade of Elan's debt rating, have materially adversely affected its
financial flexibility, including its ability to access sources of external
financing for its business. As a result, Elan's ability to meet its liquidity
requirements and capital needs may be materially adversely impacted. These
events may have a material adverse impact on Elan's business, results of
operations, liquidity and financial condition. For additional information on
the shareholder litigation and SEC investigation, please refer to Note 25 to
the Consolidated Financial Statements.

As a result of Elan's failure to timely complete and file with the SEC Elan's
Annual Report on Form 20-F for its fiscal year ended 31 December 2002, on 30
June 2003, Elan defaulted under certain covenants contained in the agreements
governing the EPIL II Notes and the Series B and Series C Guaranteed Notes
issued by EPIL III. The covenants required that Elan provide to each of the
holders of such notes Elan's audited consolidated financial statements,
together with an officer's certificate relating thereto, on or prior to 29 June
2003. On 15 July 2003, Elan also defaulted under a covenant contained in the
indenture governing the 7.25% Senior Notes that required Elan to file its 2002
Annual Report on Form 20-F with the SEC on or prior to 15 July 2003.

Commencing on 29 July 2003, Elan received a series of separate agreements from
a majority of the holders of the EPIL II Notes and the holders of the Series B
and Series C Guaranteed Notes waiving compliance by Elan with the applicable
covenants described above. The series of waivers was effective through 5
September 2003. With the completion of this Annual Report and Form 20-F and the
expected filing with the SEC of Elan's 2002 Annual Report on Form 20-F, the
defaults described above will be cured in all respects. In the absence of the
waivers, the defaults under the EPIL II Notes and the Series B and Series C
Guaranteed Notes would have become events of default on 30 July 2003. In the
absence of the completion and filing with the SEC of Elan's 2002 Annual Report
on Form 20-F, the default under the indenture governing the 7.25% Senior Notes
would become an event of default on 16 September 2003.

Elan believes that it has sufficient current cash, liquid resources and
realisable assets and investments to meet its near-term liquidity requirements.
Longer-term liquidity requirements will need to be met out of future operating
cash flows, financial and other asset


- --------------------------------------------------------------------------------

- --------------------------------------------------------------------------------

realisations and future financing. However, certain events, including material
adverse legal judgements, fines, penalties or settlements arising from Elan's
pending litigation or governmental investigations, a material deterioration in
Elan's operating performance as a result of Elan's inability to timely receive
marketing approval for products under development or otherwise or the
occurrence of other circumstances or events described under "Risk Factors",
could materially adversely affect its ability to meet its liquidity
requirements.

Elan continually evaluates its liquidity requirements, capital needs and
availability of resources in view of, among other things, its alternative uses
of capital, its debt service requirements, the cost of debt and equity capital
and estimated future operating cash flow. As a result of this process, Elan has
in the past and may in the future seek to raise additional capital, restructure
or refinance its outstanding debt, repurchase Ordinary Shares or ADSs,
repurchase its outstanding debt, including the LYONs, in the open market or
pursuant to privately negotiated transactions, consider the sale of interests
in subsidiaries, marketable investment securities or other assets or the
rationalisation of products, or take a combination of such steps or other steps
to increase or manage its liquidity and capital resources. Any such actions or
steps could be material. In the normal course of business, Elan may
investigate, evaluate, discuss and engage in future company or product
acquisitions, capital expenditures, investments and other business
opportunities. In the event of any future acquisitions, capital expenditures,
investments or other business opportunities, Elan may consider using available
cash or raising additional capital, including the issuance of additional debt.

SHAREHOLDERS' FUNDS

Shareholders' funds at 31 December 2002 decreased to $1,460.0 million from
$5,054.5 million at 31 December 2001, a decrease of $3,594.5 million. This
decrease was comprised principally of $3,615.1 million in retained loss for the
year.

CAPITAL EXPENDITURE AND INVESTMENT

The decrease in intangible fixed assets to $2,079.5 million at 31 December 2002
from $4,526.2 million at 31 December 2001 primarily reflects the impairment
charges for goodwill arising from the acquisition of Dura, Liposome, Quadrant
and Sano of $854.9 million, $111.8 million, $78.2 million and $2.4 million,
respectively, and impairment charges to acquired IP arising from the
acquisitions of Sano and Axogen of $87.4 million and $28.4 million,
respectively. It also reflects impairment charges for licences and patents of
$421.8 million, which primarily relate to the pain product line acquired from
Roxane ($86.3 million), Myobloc ($77.7 million), Delsys ($45.7 million),
Naprelan ($35.7 million), Myambutol ($32.7 million), dermatology products
($29.8 million) and Frova ($29.4 million). Intangible fixed assets with a net
book value of $412.3 million were disposed of during the year, comprising
principally $320.2 million in relation to Abelcet intangibles. The intangible
assets amortisation charge for 2002 amounted to $264.5 million and contingent
product payments of $224.3 million were terminated in 2002. The increase in
tangible fixed assets to $459.3 million at 31 December 2002 from $401.1 million
at 31 December 2001 primarily reflects the growth in assets employed in Elan's
development, manufacturing, selling and marketing infrastructure. The decrease
in non-current financial fixed assets to $734.6 million at 31 December 2002
from $1,957.1 million at 31 December 2001 primarily reflects impairment charges
of $1,045.9 million and disposals of $392.4 million, offset by additions of
$174.4 million.

Elan's capital expenditures during 2002 amounted to $182.3 million. During
2003, Elan expects to spend approximately $30 million on capital expenditures.

During 2002, Elan incurred research and development expenditures of $517.3
million. Elan anticipates that its research and development expenditures for
2003 will be lower than the amount incurred in 2002.

Elan believes that its current and planned manufacturing, research, product
development and corporate facilities are adequate for its current and projected
needs. Elan will use its resources to make such capital expenditures as are
necessary from time to time and also to make investments in the purchase or
licensing of products and technologies and in marketing and other alliances
with third parties to support Elan's long term strategic objectives.

POST BALANCE SHEET EVENTS

For information regarding post balance sheet events, please refer to Note 29 to
the Consolidated Financial Statements.

U.S. GAAP

Elan's financial statements have been prepared under Irish GAAP, which differs
in certain significant respects from U.S. GAAP. The primary differences between
Elan's financial results under Irish and U.S. GAAP arise due to:

o   The accounting for the acquisition of Dura using acquisition (purchase)
    accounting under Irish GAAP and using pooling of interests (merger)
    accounting under U.S. GAAP;


- --------------------------------------------------------------------------------
ELAN CORPORATION, PLC 2002 ANNUAL REPORT AND FORM 20-F                      55


FINANCIAL REVIEW
- --------------------------------------------------------------------------------

o   The implementation of SAB 101 under U.S. GAAP which results in differences
    in the accounting for revenue between Irish and U.S. GAAP. SAB 101 does not
    apply under Irish GAAP;

o   The expensing of acquired in-process research and development ("IPR&D")
    costs under U.S. GAAP, which amounts were capitalised under Irish GAAP; and

o   The consolidation of EPIL and EPIL II under Irish GAAP. Under U.S. GAAP,
    EPIL (prior to March 2001) and EPIL II have not been consolidated, as they
    are qualifying special purpose entities within the meaning of SFAS No. 125
    "Accounting for Transfers and Servicing of Financial Assets and
    Extinguishment of Liabilities" ("SFAS No. 125"), as grandfathered under SFAS
    No. 140 "Accounting for Transfers and Servicing of Financial Assets and
    Extinguishments of Liabilities" ("SFAS No. 140"). EPIL was a qualifying
    special purpose entity and was not consolidated under U.S. GAAP prior to
    March 2001. In March 2001, its qualifying status was terminated.

Net loss under Irish GAAP was $3,615.1 million for 2002 compared to a net loss
of $2,362.3 million for 2002 under U.S. GAAP. This difference of $1,252.8
million primarily reflects:


o   An impairment charge of $854.9 million arising from a write down of goodwill
    recorded on the acquisition of Dura under Irish GAAP. This impairment charge
    did not arise under U.S. GAAP; and

o   Other impairment charges of $249.6 million arising under Irish GAAP. These
    impairment charges did not arise under U.S. GAAP as such amounts were
    previously expensed as acquired IPR&D costs under U.S. GAAP in 1998 and
    2000.

Shareholders' equity at 31 December 2002 amounted to $1,460.0 million under
Irish GAAP compared to $826.9 million under U.S. GAAP, primarily reflecting the
carrying value under Irish GAAP of intangible assets that were previously
expensed as acquired IPR&D costs under U.S. GAAP, and the deferral of revenue
under U.S. GAAP due to the implementation of SAB 101.

For additional information regarding the material differences between Irish
GAAP and U.S. GAAP, please refer to Note 33 to the Consolidated Financial
Statements.

RESTATEMENT

Elan has restated its U.S. GAAP financial results as of and for the fiscal year
ended 31 December 2001 to consolidate EPIL III from its date of establishment
on 15 March 2001. Under U.S. GAAP, EPIL III has historically been accounted for
by Elan as a qualifying special purpose entity and has not, therefore, been
consolidated. In addition, Elan has adjusted its previously announced unaudited
U.S. GAAP financial information as of and for the fiscal year ended 31 December
2002 to give effect to the consolidation of EPIL III and to consolidate Shelly
Bay, an entity established by Elan, from 29 June 2002 through 30 September
2002. Shelly Bay acquired certain financial assets from EPIL III on 29 June
2002. Under Irish GAAP, EPIL III has been accounted for as a consolidated
subsidiary since its date of establishment in accordance with the requirements
of FRS 5, "Reporting the Substance of Transactions" ("FRS 5"). Therefore, the
2001 restatement does not affect the Irish GAAP financial information contained
in this Annual Report and Form 20-F. For additional information regarding the
restatement and the adjustments please refer to Note 33 to the Consolidated
Financial Statements.

2002 COMPARED TO 2001 (U.S. GAAP)

Total revenue for 2002 decreased by 22% to $1,455.1 million from $1,862.5
million for 2001.

Total revenue under U.S. GAAP was higher than under Irish GAAP by $122.1
million for 2002 and by $121.8 million for 2001. Product revenue under U.S.
GAAP was $1,101.2 million for 2002 (2001: $1,432.3 million), compared to
$1,204.5 million (2001: $1,407.0 million) under Irish GAAP. Contract revenue
under U.S. GAAP was $353.9 million (2001: $430.2 million), compared to $128.5
million (2001: $333.7 million) under Irish GAAP.

For 2002, the $103.3 million difference between product revenue under Irish
GAAP and U.S. GAAP arose principally due to the deferral under U.S. GAAP of
$117.1 million of product revenue related to the disposals of certain rights
related to Avinza, Actiq and nifedipine. Under U.S. GAAP Elan deferred and
amortised this revenue as it committed to provide services to the purchasers.
For example, Elan manufactures Avinza and nifedipine. Elan recognised $37.6
million of product revenue under U.S. GAAP from disposal of these product
rights in 2002, net of related intangible assets of $6.1 million. Elan
recognised $154.7 million of product revenue under Irish GAAP from the disposal
of these product rights in 2002, net of related intangible assets of $38.9
million. The amounts of deferred revenue under U.S. GAAP for Avinza, Actiq and
nifedipine are $96.7 million, $12.7 million and $40.5 million respectively at
31 December 2002.



Contract revenue was higher under U.S. GAAP than under Irish GAAP for both 2002
and 2001 due to the impact of SAB 101. The total difference in contract revenue
between U.S. GAAP and Irish GAAP was $225.4 million for 2002 (2001: $96.5
million). This primarily relates to the deferral and amortisation of up-front
licence fees under U.S. GAAP, where such amounts were recognised upon receipt
by Elan in prior periods under Irish GAAP. For 2002, Elan recorded contract
revenue related to the amortisation of up-front licence fees under U.S. GAAP of
$234.7 million (2001: $287.2 million), compared to licence fees recorded under
Irish GAAP of $7.1 million (2001: $173.6 million).


- --------------------------------------------------------------------------------

- --------------------------------------------------------------------------------

For additional information on the differences related to revenue recognition
between Irish GAAP and U.S. GAAP, please refer to Note 33f to the Consolidated
Financial Statements.

Other charges of $2,153.4 million for 2002 were principally comprised of
investment and guarantee related charges of $1,443.0 million and recovery plan
related and other charges of $710.4 million. Other charges of $710.4 million
include $706.4 million for the impairment of tangible and intangible assets and
$77.5 million for the impairment of goodwill, offset by a $177.9 million gain
on the disposal of Abelcet and Athena Diagnostics.

Other charges of $374.8 million for 2001 were principally comprised of asset
write-downs of $210.4 million and rationalisation, integration and similar
costs of $120.5 million. Asset write-downs primarily related to Ceclor CD and
Naprelan.

Net loss after other charges in 2002 was $2,362.3 million compared to net
income of $268.9 million in 2001. This decrease primarily reflects a decline in
revenue and the impact of other charges.

2001 COMPARED TO 2000 (U.S. GAAP)

Total revenue for 2001 increased by 22% to $1,862.5 million from $1,521.4
million for 2000.

Product revenue for 2001 increased by 37% to $1,432.3 million from $1,046.6
million for 2000. This increase in product revenue primarily resulted from
organic growth, revenue from product rationalisations and increased revenue
from product co-promotion and marketing activities. Product rationalisations,
which consisted of the disposition of non-core products through outright sale
or pursuant to distribution and royalty arrangements, contributed $251.1
million to product revenue in 2001. Product revenue from rationalisations in
2001 under Irish GAAP was $231.4 million. The difference between U.S. and Irish
GAAP relates to equity accounting for Amarin. Under Irish GAAP, Amarin was
required to be equity accounted for on a fully diluted basis in 2001, whereas
under U.S. GAAP Amarin was required to be equity accounted for on a common
stock basis in 2001. Zanaflex, the dermatology products, Skelaxin and Maxipime
contributed increased revenue for 2001 of $70.7 million, $46.3 million, $36.4
million and $35.5 million, respectively, compared to 2000. Product revenue from
co-promotion and marketing activities increased by $96.6 million for 2001 as
compared to 2000. The increase in product revenue was offset, in part, by
reduced revenue on the products rationalised during 2001 and by reduced revenue
from Naprelan. Product sales of rationalised products, which represents revenue
prior to rationalisation, was $101.7 million for 2001, compared to $229.2
million for 2000. Revenue from Naprelan declined by $33.6 million in 2001,
reflecting competition and less promotional focus by Elan.

Contract revenue decreased by 9% to $430.2 million for 2001 from $474.8 million
for 2000. Elan recorded contract revenue of $287.2 million in 2001 under SAB
101, compared with $286.2 million in 2000. SAB 101 requires the deferral and
amortisation of up-front licence fees where there is a continuing involvement
with the licensed asset through the provision of research and development
services, manufacturing services or other such activities. Elan implemented SAB
101 in the fourth quarter of 2000. For the year ended 31 December 2000, Elan
recorded a non-cash charge of $344.0 million, under U.S. GAAP, for the
cumulative effect of this accounting change, relating to revenue recognised in
periods up to 31 December 1999.

Other charges of $374.8 million for 2001 were principally comprised of asset
write-downs of $210.4 million and rationalisation, integration and similar
costs of $120.5 million. Asset write-downs primarily related to Ceclor CD and
Naprelan.

Other charges of $445.7 million for 2000 were principally comprised of acquired
IPR&D of $246.0 million, Dura merger costs of $35.5 million, product withdrawal
costs of $35.6 million and rationalisation, integration and similar costs of
$128.6 million.

Net income, before the cumulative effect of the accounting change for SFAS No.
133, "Accounting for Derivative Instruments and Hedging Activities" ("SFAS No.
133") of $7.8 million in 2001, and before the cumulative effect of the impact
of SAB 101 of $(344.0) million in 2000, increased to $261.1 million for 2001
compared to $49.5 million for 2000. This increase reflects increased revenue,
offset, in part, by a decrease in interest and other income, an increase in
interest expense and by higher operating expenses. Net income after the
cumulative effect of the accounting changes in 2001 and 2000 was $268.9 million
in 2001 compared to a net loss of $294.5 million in 2000.

CASH FLOW (U.S. GAAP)

2002

Cash and cash equivalents decreased by $585.5 million in 2002. Net cash of
$148.3 million was generated from operating activities. Included in cash flow
from operating activities for 2002 was $195.0 million from proceeds of the
product disposal programme entered into as part of the recovery plan,
consisting of $100.0 million received from Ligand in relation to Avinza, $45.0
million received from Watson in relation to nifedipine, and $50.0 million
received from Anesta in relation to Actiq.

ELAN CORPORATION, PLC 2002 ANNUAL REPORT AND FORM 20-F                      57


FINANCIAL REVIEW
- --------------------------------------------------------------------------------

Cash outflows from investing activities were $63.1 million. This amount
included $315.5 million for purchases of intangible assets; purchases of
investments and marketable investment securities of $200.8 million and
purchases of tangible assets of $170.2 million. Also included was a payment of
$121.0 million to acquire the royalty rights held by Autoimmune. Cash inflows
from the disposal of tangible and intangible assets were $8.6 million and $9.4
million, respectively. Disposals of investments and marketable investment
securities resulted in a cash inflow of $283.3 million including $38.5 million
on the redemption of the Autoimmune investment and $9.3 million from the sale
of EPIL III assets in connection with the repayment of EPIL III debt. Cash of
$361.3 million was received in 2002 primarily from the disposal of the Abelcet
business. Cash received for the disposal of the remaining holding in Athena
Diagnostics (approximately 80%) was $81.8 million; approximately 20% of Athena
Diagnostics was disposed in 2001 for $41.9 million.

Financing cash outflows amounted to $681.9 million, primarily reflecting an
outflow of $325.0 million on the repayment of the Revolving Credit Facility, a
cash outflow of $160.0 million in connection with the maturity of the EPIL III
Series A Guaranteed Notes, and repayment of the 3.5% Convertible Notes in the
amount of $62.6 million. Financing cash outflows also included a cash outflow
of $126.9 million on the repurchase of approximately 19% of the LYONs (a
further $22.9 million related to this LYONs repurchase is included as interest
paid within operating activities). Financing cash inflows of $148.0 million
reflect the proceeds received in June 2002 by Shelly Bay from borrowings under
a three month bank facility. The $148.0 million was repaid in September 2002.

2001

Cash and cash equivalents increased by $796.9 million in 2001. Net cash of
$523.7 million was generated by operating activities. Included in cash flow
from operating activities for 2001 was $360.9 million for product
rationalisations.

Cash outflows in respect of investing activities were $1,368.2 million,
principally comprised of $1,208.8 million to purchase investments and
marketable investment securities and $301.0 million in additions to intangible
assets, offset, in part, by $216.8 million in disposals of investments and
marketable securities.

Financing cash inflows amounted to $1,642.1 million, principally due to the
issuance of $650.0 million of Athena Finance 7.25% Senior Notes, $550.0 million
from the issuance of EPIL III Notes and proceeds of $304.8 million from the
issuance of share capital.

EPIL II

Under U.S. GAAP, EPIL II has not been consolidated as a subsidiary of Elan.
Elan has provided a direct guarantee to the holders of the loan notes of EPIL
II for the repayment of the loan notes and the payment of any unpaid interest.
In the event that EPIL II does not meet its obligations to pay amounts due to
the noteholders, the noteholders may call upon the Elan guarantee.


For additional information on the guarantee provided by Elan to the noteholders
of EPIL II, please refer to Notes 16 and 33g to the Consolidated Financial
Statements.

INFLATION

Inflation had no material impact on Elan's operations during the year.

TREASURY POLICY

Elan uses derivative financial instruments primarily to reduce exposures to
market fluctuations in foreign exchange rates. Elan does not enter into
derivative financial instruments for trading or speculative purposes. The
treasury function operates within strict terms of reference which have been
approved by Elan's board of directors.

EXCHANGE RISK

Elan is a multinational business operating in many countries. The U.S. dollar
is the primary currency in which Elan conducts its business. The U.S. dollar is
used for planning and budgetary purposes and as the currency for financial
reporting. Elan has revenues, costs, assets and liabilities denominated in
currencies other than U.S. dollars. The Group manages its non-U.S. dollar
foreign exchange risk through derivative financial instruments.

The U.S. dollar is the base currency against which all identified transactional
foreign exchange exposures are managed and hedged. The principal risks to which
Elan is exposed are movements in the exchange rates of the U.S. dollar against
the Euro, Sterling, Swiss Franc and Japanese Yen. The main exposures are net
costs in Euro arising from a manufacturing and research presence in Ireland and
the sourcing of raw materials in European markets.

During 2002, average exchange rates were EUR1.0577 = U.S.$1. Elan sells U.S.
dollars to buy Euro for costs incurred in Euro. The recent strengthening of the
Euro against the U.S. dollar will result in a higher reported cost related to
Elan's Euro cost base in 2003 compared to 2002. However, Elan does not expect
this to be material.


- --------------------------------------------------------------------------------
58


- --------------------------------------------------------------------------------

All derivative contracts entered into are in liquid markets with credit
approved counterparties.

For additional information regarding foreign exchange risk, please refer to
Note 22 to the Consolidated Financial Statements.

INTEREST RATE RISK

Elan's liquid funds are invested primarily in U.S. dollars except for the
working capital balances of subsidiaries operating outside of the United
States. Interest rate risk is mainly confined to the variability of returns on
investment funds as the majority of Elan's debt is fixed rate. The Group's
exposure to interest rate risk is actively monitored and managed with an
average duration of less than three months. By calculating an overall exposure
to interest rate risk rather than a series of individual instrument cash flow
exposures, the Company can more readily monitor and hedge these risks. Duration
analysis recognises the time value of money and in particular, prevailing
interest rates by discounting future cash flows.

For additional information regarding interest rate risk, please refer to Note
22 to the Consolidated Financial Statements.

CREDIT RISK

Elan's treasury function transacts business with counterparties that are
considered to be low investment risk. Credit limits are established
commensurate with the credit rating of the financial institution that business
is being transacted with. Elan does not believe that it has a significant
exposure to any one financial counterparty.

Elan does not currently transact significant business in countries that are
subject to political and economic uncertainty. As a result, Elan is not
materially exposed to any sovereign risk or payment difficulties.

LIQUIDITY RISK

For additional information regarding liquidity risk and for sensitivity
analysis information, please refer to Note 22 to the Consolidated Financial
Statements.

EQUITY PRICE RISK (U.S. GAAP)

Elan is exposed to equity price risks primarily on its available for sale
securities which consist of equity investments in quoted companies. At 31
December 2002, available for sale securities had a fair value of $165.5 million
and had a cost of $160.1 million. These investments are primarily in emerging
pharmaceutical and biotechnology companies. A 10% adverse change in equity
prices would result in an approximate $17 million decrease in the fair value of
Elan's available for sale equity securities.

Elan, to its knowledge, is not directly or indirectly owned or controlled by
another entity or by any government. Elan does not know of any arrangements,
the operation of which might result in a change of control of Elan.

STATEMENT OF DIRECTORS' RESPONSIBILITIES

The following statement, which should be read in conjunction with the Auditors'
Report set out on pages 73 and 74 of this Annual Report, is made with a view to
distinguishing for shareholders the respective responsibilities of the
directors and of the auditors in relation to the financial statements.

Irish company law requires the directors to ensure that financial statements
are prepared for each financial year which give a true and fair view of the
state of affairs of Elan Corporation, plc and of the Group and of the profit or
loss for that year.

With regard to the financial statements on pages 75 to 169 of this Annual
Report, the directors have determined that it is appropriate that they continue
to be prepared on a going concern basis and consider that in their preparation:

o   Suitable accounting policies have been selected and applied consistently;

o   Judgements and estimates that are reasonable and prudent have been made; and

o   Applicable accounting standards have been followed.

The directors have a responsibility for ensuring that proper books of account
are kept which disclose with reasonable accuracy at any time the financial
position of the Group and of Elan Corporation, plc and which enable them to
ensure that the financial statements comply with the Companies Acts (the
"Companies Acts"), 1963 to 2001, and all regulations to be construed as one
with those Acts. They also have general responsibility for taking such steps as
are reasonably open to them to safeguard the assets of the Group and to prevent
and detect fraud and other irregularities.

SERVICE CONTRACTS

Save as set out below, there are no service contracts in existence between any
of the directors and Elan.

o   On 12 February 2002, Elan entered into a consultancy agreement with Mr
    Groom, a director of Elan, whereby Mr Groom agreed to provide certain
    consultancy services to be agreed from time to time at a rate of $200,000
    per annum, together with reimbursement of properly incurred out-of-pocket
    expenses. The consultancy agreement is expected to continue until Mr Groom
    has reached the age of 70 years (being a period of approximately 5 years
    from the date of publication of this Annual Report and Form 20-F).

o   On 7 January 2003, Elan and EPI entered into an agreement with Mr Martin
    such that Mr Martin was appointed president and chief executive officer of
    Elan effective 3 February 2003. Mr Martin's annual salary under this
    agreement is $798,000. He is eligible for an annual bonus in a target amount
    equal to his salary depending on the achievement of established performance
    goals. Mr Martin was granted an initial option to purchase 1,000,000
    Ordinary Shares with an exercise price of $3.85 and vesting in three equal
    instalments on 31 December 2003, 31 December 2004 and 31 December 2005. It
    is anticipated that Elan will grant an additional option to Mr Martin to
    purchase 1,000,000 Ordinary Shares with an exercise price equal to the fair
    market value of the shares on the date of grant, vesting on the same basis
    and dates as the initial option grant, following Elan's 2003 Annual General
    Meeting.

    Commencing in 2004, Mr Martin will be considered for additional option
    grants during the term of the agreement consistent with Elan's annual option
    grant practices.

    The agreement continues until 31 December 2005 and can be extended for a
    further year on each anniversary of that date thereafter unless 90 days
    notice is given by Elan or Mr Martin prior to the applicable anniversary
    date. In general, if Mr Martin's employment is involuntarily terminated
    (other than for cause or disability) or Mr Martin leaves for good reason,
    Elan will continue to pay his salary and target bonus for the following two
    years and his outstanding options will immediately accelerate and remain
    outstanding for the following two years. If, during the first two years of
    the agreement, Elan undergoes a change in control and Mr Martin is
    involuntarily terminated, then Mr Martin will receive the benefits outlined
    in the preceding sentence together with a cash payment equal to the
    hypothetical value of the options to purchase 1,000,000 Ordinary Shares
    anticipated to be granted following Elan's 2003 Annual General Meeting, to
    the extent not then granted, and a lump sum payment in an amount equal to
    $5.0 million if the change of control occurs in the first year of the term,
    or $3.0 million if it occurs in the second year of the term.

    Mr Martin will be eligible to participate in the pension, medical,
    disability and life insurance plans applicable to senior executives in
    accordance with the terms of those plans. He may also receive financial
    planning and tax support and advice from the provider of his choice at a
    reasonable and customary annual cost.

o   On 1 July 1986, Athena Neurosciences entered into a consultancy agreement
    with Dr Selkoe whereby Dr Selkoe agreed to provide certain consultancy
    services in the field of AD for a fee to be fixed annually, together with
    the reimbursement for all reasonable travel and other expenses incurred. The
    consultancy agreement renews automatically, unless notice of termination is
    provided 60 days prior to the anniversary date. No such notice has been
    provided.

    On 1 April 2002, EPI entered into a consultancy agreement with Dr Selkoe
    whereby Dr Selkoe agreed to provide certain consultancy services, including
    services in the field of immunological approaches to the treatment of AD for
    a period of one year for a fee not to exceed $12,000.

CORPORATE GOVERNANCE
- --------------------------------------------------------------------------------



- --------------------------------------------------------------------------------

POLICIES

Elan is committed to the highest standards of corporate governance and
compliance. The Company complies with the provisions of The Combined Code as
defined below.

In 1998, the Hempel Committee on Corporate Governance reviewed and brought
together the guidelines and codes which had been developed by the Cadbury and
Greenbury Committees and produced The Combined Code--Principles of Good
Governance and Code of Best Practice ("The Combined Code"). The Combined Code
was adopted by the London Stock Exchange in June 1998 and by the Irish Stock
Exchange in December 1998. One of the requirements of The Combined Code is that
listed companies make a statement in relation to how they have complied with
this code.

In early 2002, a review of the Company's corporate governance structures and
procedures was undertaken by the Company's and the directors' external legal
advisors, Shearman & Sterling and Wachtell Lipton Rosen & Katz, respectively.
Resulting from this review, on 31 May 2002 the board of directors adopted a set
of corporate governance guidelines and established four board committees, as
set out below, to replace the previous three board committees. The corporate
governance guidelines include a definition of director independence based on
the standards proposed by the NYSE. This review will be updated during 2003
following publication of the final standards proposed by the NYSE.

THE BOARD

The roles of chairman and chief executive officer are separated. The board
includes 11 independent, non-executive directors who constitute a majority of
the board. In addition, the board has appointed the Honorable Richard L.
Thornburgh as lead independent director, in accordance with the provisions of
The Combined Code and best corporate governance practice in the United States
and Ireland. As a matter of policy and good corporate governance, the majority
of the board shall comprise non-executive directors who are independent of
management and free of any relationship that, in the view of the board, could
interfere with the exercise of independent judgement as a director. The board
regularly reviews its responsibilities and those of its committees and
management. The board meets regularly throughout the year, and all of the
directors have full and timely access to the information necessary to enable
them to discharge their duties. The board has reserved certain matters to its
exclusive jurisdiction, thereby maintaining control of the Company and its
future direction. All directors are appointed by the board, as nominated by its
nominating committee, and subsequently elected by the shareholders. Procedures
are in place where directors and committees, in furtherance of their duties,
may take independent professional advice, if necessary, at the Company's
expense. The board has delegated authority over certain areas of the Company's
activities to four standing committees, as more fully described below. Each of
these committees has a written charter approved by the board. The board held 15
meetings during 2002.

EXECUTIVE COMMITTEE

The executive committee exercises the authority of the board during the
interval between board meetings, except to the extent that the board has
delegated authority to another committee or to other persons, or has reserved
authority to itself or as limited by Irish law. The members of the committee
are Dr Armen, chairman, Mr Crowley, Ms Gray, Mr McLaughlin and Mr Tully. The
executive committee held 9 formal meetings during 2002.

AUDIT COMMITTEE

The audit committee, composed entirely of non-executive directors, helps the
board in its general oversight of the Company's accounting and financial
reporting practices, internal controls and audit functions, and is directly
responsible for the appointment, compensation and oversight of the work of
Elan's independent auditors. The audit committee periodically reviews the
effectiveness of the system of internal financial control. It monitors the
adequacy of internal accounting practices, procedures and controls, and reviews
all significant changes in accounting policies. The committee meets regularly
with the internal and external auditors and addresses all issues raised and

recommendations made by them. The members of the committee are Mr McLaughlin,
chairman, Dr Gillespie and Mr McGowan. During 2002, the audit committee held 8
formal meetings.

COMPENSATION COMMITTEE

The compensation committee, composed entirely of non-executive directors,
reviews the compensation philosophy and policies of the Company with respect to
executive compensation, fringe benefits and other compensation matters. The
committee determines the compensation of the chief executive officer and other
executive directors and reviews the compensation of the other members of the
executive management. The committee also administers the Company's share option
plans. The members of the committee are Dr McIntyre, chairman, Mr Crowley, Ms
Gray and Mr Tully. During 2002, the compensation committee held 11 formal
meetings. For more information, see "Report of the Compensation Committee".

NOMINATING COMMITTEE

The nominating committee, composed entirely of non-executive directors, reviews
on an ongoing basis the membership of the board of directors and of the board
committees and the performance of the directors. It recommends new appointments
to fill any vacancy that is anticipated or arises on the board of directors. It
reviews and recommends changes in respect of the functions of the various
committees of the board. The members of the committee are Mr Thornburgh,
chairman, Ms Gray, Mr McGowan, Mr McLaughlin and Mr Tully. During 2002, the
nominating committee held 2 formal meetings.

RELATIONS WITH SHAREHOLDERS

Elan communicates regularly with its shareholders throughout the year,
including following the release of quarterly and annual results, and after
major developments. All shareholders are given adequate notice of the Annual
General Meeting.

INTERNAL CONTROL

The board of directors has overall responsibility for the Group's system of
internal control and for monitoring its effectiveness. Management is
responsible for the planning and implementation of the system of internal
control and ensuring that these controls apply throughout the Group. The system
of internal control is designed to provide reasonable, but not absolute,
assurance against material misstatement or loss.

The key procedures that have been established to provide effective internal
control include:

o   A clear focus on business objectives is set by the board having considered
    the risk profile of the Group;

o   A formalised risk reporting system. Significant business risks are addressed
    at each board meeting;

o   A clearly defined organisational structure under the day to day direction of
    its chief executive officer. Defined lines of responsibility and delegation
    of authority have been established within which the Group's activities can
    be planned, executed, controlled and monitored to achieve the strategic
    objectives which the board has adopted for Elan;

o   A comprehensive system for reporting financial results to the board. This
    includes a budgeting system with an annual budget approved by the board. The
    board compares actual results with budgeted results regularly. Management
    accounts are prepared on a timely basis. They include a profit and loss
    account, balance sheet, cash flow and capital expenditure report, together
    with an analysis of performance of key operating divisions and subsidiaries;

o   A system of management and financial reporting, treasury management and
    project appraisal. Management is responsible for reporting to the board on
    its progress in achieving objectives. The system of reporting covers trading
    activities, operational issues, financial performance, working capital, cash
    flow and asset management. This reporting happens in a timely and regular
    manner. In this context, progress is monitored against annual budgets and
    longer term objectives; and

o   Establishment of Corporate Compliance and Internal Audit departments which
    review key systems and controls.

The directors reviewed the Group's system of internal control and also examined
the full range of risks affecting the Group and the appropriateness of the
internal control structures to manage and monitor these risks. This process
involved a confirmation that appropriate systems of internal control were in
place throughout the financial year and up to the date of signing of these
financial statements. It also involved an assessment of the ongoing process for
the identification, management and control of the individual risks and of the
role of the various Group Risk Management Functions and the extent to which
areas of significant challenges facing the Group are understood and are being
addressed. No material unaddressed issues emerged from this assessment. The
directors confirm that they have reviewed, in accordance with the Turnbull
Guidance, the effectiveness of the Group's systems of internal control for the
year ended 31 December 2002.

- --------------------------------------------------------------------------------

GOING CONCERN

The directors, having made inquiries, believe that Elan has adequate resources
to continue in operational existence for the foreseeable future and that it is
appropriate to continue to adopt the going concern basis in preparing the
financial statements.

REPORT OF THE COMPENSATION COMMITTEE

The terms of reference for the committee are to determine the compensation,
terms and conditions of employment of the chief executive officer and other
executive directors and to review the recommendations of the chief executive
officer with respect to the remuneration and terms and conditions of employment
of the Company's senior management. The committee also exercises all the powers
of the board of directors to issue Ordinary Shares on the exercise of share
options and to generally administer the Company's share option plans.

The chief executive officer attends meetings of the committee except when his
own remuneration is being considered.

Each member of the committee is nominated to serve for a three year term
subject to a maximum of two terms of continuous service.

For additional information regarding directors' remuneration, shareholdings and
share options, please refer to Note 6 to the Consolidated Financial Statements
and "Directors' Interests", "Directors' Options" and "Directors' Remuneration"
in the Directors' Report.

Remuneration Policy

The Company's policy on executive directors' remuneration is to set
remuneration levels which are appropriate for its senior executives having
regard to their substantial responsibilities, their individual performance and
the performance of the Company as a whole. It is the policy of the committee to
set remuneration levels after a review of remuneration packages of executives
in the pharmaceutical industry. During 2002, the committee took external advice
from independent benefit consultants on executive remuneration. In framing
remuneration policy, consideration has been given to Section B of the Code of
Best Practice of The Combined Code as issued by the London and Irish Stock
Exchanges.

The typical elements of the remuneration package for executive directors
include basic salary and benefits, annual cash incentive bonus, pensions and
participation in share option plans.

It is the policy of the committee to grant options to management to encourage
identification with shareholders' interests and to link performance to the long
term share price performance of the Company.

Executive Directors' Basic Salary

The basic salaries of executive directors are reviewed annually having regard
to personal performance, company performance and market practice.

Annual Cash Incentive Bonus

An annual cash incentive bonus, which is not pensionable, is paid on the
recommendation of the committee to executive directors. Bonus determination is
not based on specific financial or operational targets, but on individual and
company performance.

Share Option Plans

It is the policy of the committee, in common with other companies operating in
the pharmaceutical industry, to award share options to management and
employees. The options generally vest between one and five years. These plans
do not contain any performance conditions.

INDEPENDENT AUDITORS' REPORT
- --------------------------------------------------------------------------------



- --------------------------------------------------------------------------------

TO THE MEMBERS OF ELAN CORPORATION, PLC

We have audited the financial statements on pages 75 to 169.

RESPECTIVE RESPONSIBILITIES OF DIRECTORS AND AUDITORS IN RELATION TO THE ANNUAL
REPORT AND FORM 20-F

The directors are responsible for having the Annual Report and Form 20-F
prepared. As described on page 67, this includes responsibility for preparing
the financial statements in accordance with applicable Irish Law and accounting
standards; the directors have also presented additional information under U.S.
requirements. Our responsibilities, as independent auditors, are established in
Ireland by statute, the Auditing Practices Board, the Listing Rules of the
Irish Stock Exchange and by our profession's ethical guidance.

We report to you our opinion as to whether the financial statements give a true
and fair view and are properly prepared in accordance with the Companies Acts.
As also required by the Companies Acts, we state whether we have obtained all
the information and explanations we require for our audit, whether the
Company's balance sheet agrees with the books of account and report to you our
opinion as to whether:

o   the Company has kept proper books of account;

o   the directors' report is consistent with the financial statements; and

o   at the balance sheet date, a financial situation existed that may require
    the Company to hold an extraordinary general meeting on the grounds that the
    net assets of the Company, as shown in the financial statements, are less
    than half of its share capital.

We also report to you if, in our opinion, information specified by law or by
the Listing Rules regarding directors' remuneration and transactions with the
Group is not disclosed.

We review whether the statement on page 69 reflects the Company's compliance
with the seven provisions of The Combined Code specified for our review by the
Irish Stock Exchange, and we report if it does not. We are not required to
consider whether the board's statements on internal control cover all risks and
controls, or form an opinion on the effectiveness of the Group's corporate
governance procedures or its risk and control procedures.

We read the other information contained in the Annual Report and Form 20-F,
including the corporate governance statement, and consider whether it is
consistent with the audited financial statements. We consider the implications
for our report if we become aware of any apparent misstatements or material
inconsistencies with the financial statements.

BASIS OF AUDIT OPINION

We conducted our audit in accordance with Auditing Standards issued by the
Auditing Practices Board. An audit includes examination, on a test basis, of
evidence relevant to the amounts and disclosures in the financial statements.
It also includes an assessment of the significant estimates and judgements made
by the directors in the preparation of the financial statements, and of whether
the accounting policies are appropriate to the Group's circumstances,
consistently applied and adequately disclosed.

We planned and performed our audit so as to obtain all the information and
explanations which we considered necessary in order to provide us with
sufficient evidence to give reasonable assurance that the financial statements
are free from material misstatement, whether caused by fraud or other
irregularity or error. In forming our opinion, we also evaluated the overall
adequacy of the presentation of information in the financial statements.

Fundamental Uncertainty

In forming our opinion, we considered the disclosures in note 25 to the
financial statements relating to the Company and certain of its former and
current officers and directors being named as defendants in a putative class
action in the U.S. District Court for the Southern

INDEPENDENT AUDITORS' REPORT
- --------------------------------------------------------------------------------

District of New York, and the Company being the subject of an investigation by
the SEC's Division of Enforcement which commenced on or about 12 February 2002.
Elan is unable to predict or determine the outcome of the class action or the
SEC investigation or reasonably to estimate the amounts or range of loss, if
any, with respect to the resolution of the class action or the SEC
investigation. The possible outcome or resolution of the SEC investigation or
the class action could require Elan to make substantial payments. Our opinion
is not qualified in this respect.

OPINION

In our opinion, the financial statements give a true and fair view of the state
of affairs of the Group and the Company as at 31 December 2002 and of the loss
of the Group for the year then ended, and have been properly prepared in
accordance with the Companies Acts, 1963 to 2001, and all Regulations to be
construed as one with those Acts.

Generally accepted accounting principles in Ireland vary in certain significant
respects from accounting principles generally accepted in the United States.
Application of generally accepted accounting principles in the United States
would have affected results of operations for each of the years in the three
year period ended 31 December 2002, and shareholders' equity as at 31 December
2002 and 2001, to the extent summarised on pages 142 to 169 of the financial
statements.

We have obtained all the information and explanations we considered necessary
for the purposes of our audit. In our opinion, proper books of account have
been kept by the Company. The balance sheet of the Company is in agreement with
the books of account.

In our opinion, the information given in the Directors' Report on pages 60 to
68 is consistent with the financial statements.

The net assets of the Company, as stated in the balance sheet on page 80 are
more than half of the amount of its called-up share capital and, in our
opinion, on that basis there did not exist at 31 December 2002 a financial
situation which, under Section 40(1) of the Companies (Amendment) Act, 1983,
would require the convening of an extraordinary general meeting of the Company.

1 SIGNIFICANT ACCOUNTING POLICIES

The financial statements are prepared in U.S. dollars under the historical cost
convention and in accordance with Irish GAAP and comply with the Financial
Reporting Standards ("FRS") of the Accounting Standards Board, as promulgated
by the Institute of Chartered Accountants in Ireland. Where there are
significant differences to U.S. GAAP, these have been described in Note 33 to
the Consolidated Financial Statements.

The following accounting policies have been applied consistently in dealing
with items which are considered material in relation to the Company's financial
statements with the exception of the Company's accounting policy for deferred
taxation. The Company has adopted FRS 19 "Deferred Taxation" ("FRS 19") which
applies to all accounting periods ending on or after 23 January 2002. Prior to
the adoption of FRS 19, deferred tax was provided in respect of timing
differences only to the extent that there was a reasonable probability that a
liability or asset would crystallise. Under FRS 19, deferred tax is provided on
all timing differences, with deferred tax assets being recognised when it is
likely that they will be recovered. The adoption of FRS 19 has had no impact on
the historical results of the Company and as such prior year results have not
been restated to reflect this change.

A BASIS OF CONSOLIDATION AND PRESENTATION OF FINANCIAL INFORMATION

The Consolidated Financial Statements include the accounts of Elan and all of
its subsidiary undertakings and its share of profits or losses of associated
undertakings. Associated undertakings are accounted for under the equity method
of accounting. All significant intercompany profits, transactions and account
balances have been eliminated.

The Company has made significant losses during the last two financial years.
However, the directors, having made inquiries, believe that Elan has adequate
resources to continue in operational existence for the foreseeable future and
that it is appropriate to continue to adopt the going concern basis in
preparing the financial statements.

B REVENUE

Elan's revenues are derived from a number of different sources and are
classified within the categories of product revenue and contract revenue.
Revenue is shown net of value added tax and other sales taxes, trade discounts
and rebates.

Product revenue includes (i) the sale of products, (ii) royalties, (iii) the
sales of product rights and related inventory (referred to as product disposals
and product rationalisations), and (iv) product co-promotion, marketing and
similar activities.

The sale of products consists of the sale of pharmaceutical drugs and
diagnostic products primarily to wholesalers and physicians. Royalties arise
when Elan receives a percentage of revenue on a product marketed by a third
party. Revenue from the sale of product rights and related inventory consists
of the proceeds from the disposal of products, inventory and intellectual
property less the write-off of the related intangible assets. Revenue from
product co-promotion, marketing and similar activities consists of the
reimbursement of commercialisation expenses from Elan's risk-sharing
arrangements. Elan had two risk-sharing arrangements which were with Pharma
Marketing and Autoimmune.

Product revenue from the sale of products is recognised when title passes, net
of applicable discounts and allowances. Other product revenues are recognised
based on the terms of the applicable contract.

Contract revenue includes (i) licence fees, (ii) research revenue and (iii)
contract revenue from risk-sharing arrangements. Contract revenue arises from
contracts to perform research and development services on behalf of clients
and/or technology licensing and business ventures. Contract revenue is
recognised when earned and non-refundable, and when Elan has no future
obligation with respect to the revenue, in accordance with the terms prescribed
in the applicable contract.

Licence fees are up-front or milestone payments for intellectual property and
technology owned by Elan. Research revenue consists of payments or milestones
arising from research and development activities performed by Elan on behalf of
third parties. Contract revenue from risk-sharing arrangements consists of the
reimbursement of research and development costs by Pharma Marketing and
Autoimmune.

C EXCEPTIONAL ITEMS

Exceptional items are those items that in management's judgement are material
items which derive from events or transactions that fall within the ordinary
activities of the Group and which individually or, if of a similar type, in
aggregate, need to be disclosed by virtue of their size or incidence.

D DISCONTINUED OPERATIONS

A discontinued operation is classified as an operation of the business which is
(i) sold or terminated and the sale or termination has been completed during
the year or within three months following the year end, (ii) the former
activities have ceased permanently, (iii) the operation had a material effect
on the nature and focus of the business and (iv) its financial results are
clearly distinguishable.

E TANGIBLE FIXED ASSETS AND IMPAIRMENT

Tangible fixed assets are stated at cost less accumulated depreciation.
Depreciation of tangible fixed assets is computed using the straight-line
method based on estimated useful lives at the following annual rates:

- --------------------------------------------------------------
                                                             %
- --------------------------------------------------------------
Buildings                                              2.5-6.6
- --------------------------------------------------------------
Leasehold improvements            Lease term or 2.5% if higher
- --------------------------------------------------------------
Plant and equipment                                       5-40
- --------------------------------------------------------------

The average depreciation rate for buildings is 3% and for plant and equipment
is 12%.

Where events or circumstances are present which indicate that the carrying
amount of a tangible asset may not be recoverable, the Company estimates the
net realisable value (estimated sales proceeds less costs to sell) or the value
in use (present value of future cash flows) expected to result from use of the
asset and its eventual disposition. The recoverable amount is the higher of net
realisable value and value in use. Where the recoverable amount is less than
the carrying amount of the asset, the Company recognises an impairment loss
which is charged to the profit and loss account. Otherwise, no loss is
recognised.

F INTANGIBLE FIXED ASSETS AND IMPAIRMENT

Patents, licences, acquired IP and goodwill are stated at the lower of cost or
valuation. Patents and licences are amortised over their expected useful lives,
which range between 2 years and 20 years. The average amortisation period for
patents and licences is approximately 16 years. Goodwill arising on
acquisitions since 1998 is capitalised and amortised to the profit and loss
account over the period during which the benefits are expected to accrue, but
in no case greater than 20 years. The average amortisation period for goodwill
is 18 years. Prior to 1 January 1998, goodwill was written-off directly to
consolidated reserves in the year of acquisition. Acquired IP arising on
acquisitions is capitalised and amortised to the profit and loss account over
its useful economic life. The useful economic life commences upon generation of
product revenue relating to the acquired IP.

Where events or circumstances are present which indicate that the carrying
amount of an intangible asset may not be recoverable, the Company estimates the
net realisable value (estimated sales proceeds less costs to sell) or the value
in use (present value of future cash flows) expected to result from use of the
asset and its eventual disposition. The recoverable amount is the higher of net
realisable value and value in use. Where the recoverable amount is less than
the carrying amount of the asset, the Company recognises an impairment loss
which is charged to the profit and loss account. Otherwise, no loss is
recognised.

G STOCKS

Stocks are valued at the lower of cost or market value. Cost in the case of raw
materials and supplies is calculated on a first-in, first-out basis and
comprises the purchase price, including import duties, transport and handling
costs and any other directly attributable costs, less trade discounts. Cost in
the case of work-in-progress and finished goods comprises direct labour,
material costs and attributable overheads.

H RESEARCH AND DEVELOPMENT

Research and development expenditure is charged to the profit and loss account
in the period in which it is incurred.

I TAXATION

Current tax, including Irish corporation tax and foreign taxes, is provided on
the Group's taxable profits, at amounts expected to be paid (or recovered)
using the tax rates and laws that have been enacted or substantially enacted by
the balance sheet date. Deferred taxation is recognised in full in respect of
timing differences that have originated but not reversed at the balance sheet
date.

J FOREIGN CURRENCIES AND TRANSLATION OF SUBSIDIARY AND ASSOCIATED UNDERTAKINGS

Transactions in foreign currencies are recorded at the rate ruling at the date
of the transaction. The resulting monetary assets and liabilities are
translated into U.S. dollars at exchange rates prevailing at the balance sheet
date. Profits and losses are dealt with in the profit and loss account and,
where material, they are separately disclosed.

The assets and liabilities of subsidiary undertakings are translated using
year-end rates and income is translated at average rates. The cumulative effect
of exchange differences arising on consolidation of the net investment in
overseas subsidiaries and associates are taken directly to reserves via the
Consolidated Statement of Total Recognised Gains and Losses.

K DERIVATIVE FINANCIAL INSTRUMENTS

The Company enters into transactions in the normal course of business using a
variety of financial instruments in order to hedge against exposures to
fluctuating exchange and interest rates.

Derivative financial instruments are utilised to mitigate interest rate and
currency exposures. Forward currency contracts and options and interest rate
derivatives are marked to market at each balance sheet date and the resulting
gains and losses are recognised in the profit and loss account. The carrying
value of derivative financial instruments is generally reported within current
assets or other current liabilities.

L FINANCIAL ASSET INVESTMENTS AND IMPAIRMENT

Financial asset investments, other than associated undertakings, are stated at
cost less provision for impairment in value. The carrying values of financial
assets are assessed for impairment using established financial methodologies,
including quoted market prices for quoted equity securities. Unquoted equity
investments and non-traded securities of public entities are assessed using
methodologies including the Black-Scholes option-pricing model, the valuation
achieved in the most recent private placement by an investee, an assessment of
the impact of general private equity market conditions, and discounted
projected future cash flow models. The factors affecting carrying values
include both general financial market conditions for pharmaceutical and
biotechnology companies and factors specific to a particular company.

Financial current asset investments held for trading purposes are stated at
market value with interest and similar income taken to the profit and loss
account on a receivable basis. Other financial current asset investments are
accounted for on an amortised cost basis.

Investments in associated undertakings are accounted for under the equity
method where the Company holds voting equity in the investee and exercises
significant influence over the operating and financial policies of the
investee. Significant influence may exist even if the Company owns less than
20% of the investee's equity depending on the existence of factors such as
representation on the board of directors, participation in policy making
processes, material intercompany transactions, interchange of managerial
personnel or technological dependency. Certain circumstances, such as majority
ownership by another company, can offset the impact of such factors. The
determination to use cost or equity accounting requires a significant degree of
judgement on the facts and circumstances of a particular investment. Financial
asset investments which are accounted for under the equity method are stated at
cost, adjusted for the Company's share of the earnings or losses of the
investee after the date of investment, less any provision for impairment in
value.

M FINANCING COSTS

Debt finance costs are allocated to financial reporting periods over the term
of the related debt at a constant rate on the carrying amount. The carrying
amount of debt includes related financing costs.


- --------------------------------------------------------------------------------
84


- --------------------------------------------------------------------------------

N PENSIONS

The regular cost of providing benefits under defined benefit plans is charged
to the profit and loss account over the service lives of the members of the
schemes. The regular costs are determined in consultation with independent,
external, qualified actuaries. Variations from regular costs, where they arise,
are allocated to operating profit/(loss) over the expected remaining service
lives of the members.

The costs of providing defined contribution benefit plans are expensed as
incurred.

O LEASING

Tangible fixed assets, acquired under a lease which transfers substantially all
of the risks and rewards of ownership to the Company, are capitalised as a
fixed asset. Amounts payable under such leases (finance leases), net of finance
charges, are shown as short or medium term borrowings as appropriate. Finance
charges on finance leases are charged to the profit and loss account over the
term of the lease to give a constant rate of charge in proportion to the
capital balances outstanding. Rentals on operating leases are charged to the
profit and loss account as incurred.

P STOCK COMPENSATION

Stock option compensation expense is the difference between the market value of
shares at the date of the option grant and the amount of the consideration, if
any, that participants may be required to pay for the shares.

Q FINANCE CHARGES AND PRODUCT ACQUISITION ACCRUALS

Deferred and contingent payments on product acquisitions are recognised in
creditors on a time-discounted basis. The Company accrues such amounts where
payment is probable. Such amounts include contingent payments based on future
product revenues and future option payments that the Company may make to
acquire such products. A related finance charge is included annually in the
profit and loss account.

R DESCRIPTION OF BUSINESS

Elan is a worldwide biopharmaceutical company headquartered in Dublin, Ireland.
The Company is focused on the discovery, development, manufacturing, selling
and marketing of novel therapeutic products in neurology, pain management and
autoimmune diseases.

During 2001 and through mid-2002, the Company conducted its operations through
two primary business units: Biopharmaceuticals and Drug Delivery. On 31 July
2002, the Company announced a recovery plan to restructure its businesses,
assets and balance sheet and to meet its financial obligations. The Company
will focus on three core therapeutic areas; neurology, pain management and
autoimmune diseases. The Group was reorganised and two new units were created:
Core Elan and Elan Enterprises. Please refer to Note 3 to the Consolidated
Financial Statements for further information on the recovery plan.

Core Elan is engaged in pharmaceutical commercial activities and
biopharmaceutical research and development activities. Core Elan is also
engaged in manufacturing activities at its facility in Athlone, Ireland. Elan's
pharmaceutical commercial activities include the marketing of products in the
therapeutic areas of neurology, pain management and infectious diseases.
Biopharmaceutical research and development activities include the discovery and
development of products in the therapeutic areas of neurology, pain management
and autoimmune diseases.

Elan Enterprises is mainly comprised of Elan's drug delivery businesses and
other assets such as business ventures and non-core pharmaceutical products.
Drug delivery activities have historically included the development, licensing
and marketing of drug delivery products, technologies and services to
pharmaceutical industry clients on a worldwide basis. Elan Enterprises is
seeking to dispose of many of these businesses and assets.

Since 1996, Elan has pursued collaborations with biotechnology, drug delivery
and pharmaceutical companies through a programme referred to as "the business
venture programme". As part of Elan's recovery plan, Elan has announced its
intention to restructure or terminate substantially all of its business
ventures. See Note 1b to the Consolidated Financial Statements for a summary of
the investments made and licence fees received from the business venture
arrangements. Please refer to Note 26 to the Consolidated Financial Statements
for further information on the business ventures.

NOTES RELATING TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

Elan has in the past entered into risk-sharing arrangements. Please refer to
Note 24 to the Consolidated Financial Statements for information on Elan's
risk-sharing arrangements. Elan does not expect to earn any revenues from these
risk-sharing arrangements or upfront licence fees from business ventures in the
future.

The composition of Elan's revenue for 2002, 2001 and 2000 has been described
above in Note 1b to the Consolidated Financial Statements.

S RISKS AND UNCERTAINTIES

The Company is subject to certain risks and uncertainties arising from a number
of factors including competition, government regulation, litigation, liquidity
and financing, continued successful licensing and marketing, third party
reimbursement, pricing pressure, unpredictability of patent protection, the
value of its investments and other assets, unpredictability of product
approvals, tax reform and environmental liabilities. The Company makes a
provision for these risks and uncertainties when it has a present obligation as
a result of a past event in respect of which it is probable that a transfer of
economic benefits will be required to settle the obligation, and a reliable
estimate can be made of the amount, or the minimum amount, that will be
required to settle the obligation.

T USE OF ESTIMATES

The preparation of the Consolidated Financial Statements in conformity with
Irish GAAP requires management to make estimates and assumptions that affect
reported amounts and disclosures in these financial statements. Actual results
could differ from those estimates.

2 SEGMENT INFORMATION

Elan's business is currently conducted through two business units, Core Elan and
Elan Enterprises.

Core Elan is engaged in pharmaceutical commercial activities and
biopharmaceutical research and development activities. Elan Enterprises is
mainly comprised of Elan's drug delivery businesses and other assets such as
business ventures and non-core pharmaceutical products.

3 EXCEPTIONAL ITEMS

Exceptional items are those items that in management's judgement are material
items which derive from events or transactions that fall within the ordinary
activities of the Group and which individually or, if of a similar type, in
aggregate, need to be disclosed by virtue of their size or incidence.

The exceptional revenues and costs incurred in 2002, 2001 and 2000 are included
in the profit and loss account under the following statutory headings:



- --------------------------------------------------------------------------------------

- --------------------------------------------------------------------------------------


2002

In 2002, Elan incurred net exceptional charges of $2,939.4 million.

The exceptional items for 2002 mainly relate to the:

o   Implementation of Elan's recovery plan. Elan announced this recovery plan in
    July 2002;

o   Significant decline during 2002 in the financial markets for investments in
    emerging biotechnology, drug delivery and pharmaceutical companies; and

o   Introduction of generic competitors to some of Elan's products.

On 31 July 2002, Elan announced a recovery plan to restructure its businesses,
assets and balance sheet. Elan decided to focus on three core therapeutic
areas. These are neurology, pain management and autoimmune diseases. A key
element of the recovery plan is the divestiture of businesses and products. The
exceptional charges and revenue arising from the recovery plan mainly relate to
the:

o   Sale of businesses and products. The carrying value of these assets have
    been written down, where applicable, to their estimated recoverable amounts.
    Exceptional revenue arises from the proceeds received on the disposal of
    products;

o   Discontinuance of businesses or the decision not to exercise an option to
    acquire a product. For example, Elan decided not to exercise its option to
    acquire certain dermatology products from GSK;

o  Rationalisation and restructuring expenses incurred from a reduction in the
   scope of Elan's activities, a reduction in employee numbers and related
   write-downs in the carrying value of assets;

o  Simplification of Elan's business such as the termination of the Autoimmune
   risk-sharing arrangement; and

o  Termination of substantially all of Elan's business ventures.

(A) REVENUE

Exceptional product revenue of $172.5 million for 2002 includes $154.7 million
from product disposals arising from Elan's recovery plan, as well as $17.8
million relating to product rationalisations.

On 9 December 2002, Elan announced the amendment of the terms of its
development, licence and supply agreement with Ligand regarding Avinza. Elan
received a cash payment of $100.0 million from Ligand, in return for a
reduction in the ongoing royalty rate from the previous level of 30% of net
sales of Avinza in the United States and Canada to approximately 10%. In
addition, Elan agreed to forego its option to negotiate a co-promotion
agreement with Ligand for Avinza in the United States and Canada. Elan will
continue to

manufacture the product in its Gainesville facility. Net of the write-off of
the related intangible assets, Elan recorded exceptional product revenue of
$75.6 million on the closing of this transaction.

On 3 October 2002, Elan announced that it sold its rights to Actiq in twelve
territories, principally in Europe, to Anesta. At the date of disposal, Actiq
was marketed by Elan in the United Kingdom, Ireland and Germany. Net of the
write-off of the related intangible assets, Elan recorded exceptional product
revenue of $40.3 million on the closing of this transaction.

On 23 August 2002, Elan announced a licensing agreement with Watson for
exclusive marketing rights to the 30mg and 60mg dosage strengths of Elan's
extended-release nifedipine tablets in the United States. Elan received $45.0
million in cash from Watson. Elan will continue to manufacture the products in
its Athlone facility. Net of the write-off of the related intangible assets,
Elan recorded exceptional product revenue of $38.8 million on the closing of
this transaction.


(B) COST OF SALES

Exceptional cost of sales includes a charge of $43.3 million related to the
write-off of Zanaflex inventories due to the impact of generic competition
during 2002. Other exceptional cost of sales includes $8.0 million on the write
down of the intangible asset for Mysoline, following generic competition for
this product, $5.7 million on the impairment of certain fixed assets,
severance/relocation costs of $8.4 million and other exceptional cost of sales
of $0.7 million.


(C) SELLING, GENERAL AND ADMINISTRATIVE

Exceptional selling, general and administrative expenses were $1,788.0 million.
$1,536.7 million of the exceptional expenses relate to impairment charges
arising on write-downs of intangible assets. Other exceptional selling, general
and administrative expenses were $251.3 million. These include the purchase of
royalty rights from Autoimmune, fixed asset write-downs and similar costs
arising from the restructuring of the Group as part of the recovery plan. They
also include legal costs related to the SEC investigation, shareholder
litigation and litigation provisions.

Impairment charges to goodwill relating to the acquisitions of Dura, Liposome,
Quadrant and Sano were $854.9 million, $111.8 million, $78.2 million and $2.4
million, respectively. Impairment charges to acquired IP arising from the
acquisitions of Sano and Axogen were $87.4 million and $28.4 million,
respectively. Other impairments to goodwill totalled $19.1 million. Impairment
charges to patents and licences arising on write-downs of the product
intangibles for the Pain Portfolio, Myobloc, Naprelan, Myambutol, dermatology
products and Frova were $86.3 million, $77.7 million, $35.7 million, $32.7
million, $29.8 million and $29.4 million, respectively. Other impairments to
patents and licences totalled $62.9 million.


Dura

Elan acquired Dura in November 2000 for $1,590.7 million. Dura was a specialty
pharmaceutical company engaged in the marketing and sale of prescription
products for the treatment of infectious diseases and respiratory conditions.
The Dura acquisition added over 500 hospital and primary care sales
representatives to Elan's sales and marketing infrastructure and broadened
Elan's portfolio of marketed products. The purchase price was primarily
allocated to goodwill and patents and licences. In 2002, Elan wrote down
goodwill relating to the acquisition of Dura by $854.9 million. Elan acquired
Dura in order to significantly expand its sales and marketing infrastructure.
Elan's recovery plan aims to create a research and development based
biopharmaceutical company focused in neurology, pain management and autoimmune
diseases. Therefore, Elan has decided to significantly reduce its sales and
marketing infrastructure. For example, during 2002, Elan decided to dispose of
its primary care franchise and related infrastructure. As a result of such
reductions in Elan's sales and marketing capability, the carrying value of the
Dura goodwill has been impaired.


Liposome

Elan acquired Liposome in May 2000 for $731.8 million, which included a
milestone payment of $54.0 million paid on the receipt of marketing and pricing
approval for Myocet in certain countries of the EU. Liposome was a
biotechnology company engaged in the development, manufacturing and marketing
of therapeutic products to treat cancer and related diseases. The purchase
price was primarily allocated to goodwill and patents and licences. In 2002,
under its recovery plan, Elan disposed of its U.S., Canadian and any Japanese
rights to Abelcet, and certain related assets, and allocated $119.0 million of
goodwill to the sale of the Abelcet business based on the estimated relative
fair value of the Abelcet rights disposed. In 2002, Elan wrote down the
remaining goodwill arising from the acquisition of Liposome by $111.8 million,
as under its recovery plan Elan has decided to close its oncology research and
development business. The residual value for goodwill of $86.8 million is
supported by European rights to Abelcet and Myocet.

NOTES RELATING TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------


Quadrant

Elan acquired Quadrant in December 2000 for $86.0 million. Quadrant was a drug
delivery company with proprietary formulation technology applicable to
pulmonary, oral and parenteral routes of administration. The purchase price was
primarily allocated to goodwill. In 2002, Elan wrote down goodwill arising from
the acquisition of Quadrant by $78.2 million to $Nil, as under its recovery
plan Elan decided to dispose of or close the Quadrant business. This business
was sold to a company managed by former employees of the business in July 2003.


Sano

Elan acquired Sano in February 1998 for $434.6 million. Sano was developing
transdermal drug delivery products. The purchase price was primarily allocated
to acquired IP. In 2002, Elan wrote down acquired IP and goodwill arising from
the acquisition of Sano by $87.4 million and $2.4 million, respectively, as
under its recovery plan Elan decided to dispose of its transdermal business.
This business was sold to Nitto Americas in July 2003.


Axogen

Elan acquired Axogen in December 1999 for $268.4 million. The purchase price
was primarily allocated to patents and licences and acquired IP. In 2002, Elan
wrote down acquired IP relating to Myobloc, arising from the acquisition of
Axogen, by $28.4 million. Elan also wrote down $77.7 million in respect of
other Myobloc intangible assets. The carrying value of Myobloc was written down
due to lower than expected revenue from this product for 2002 and as under its
recovery plan Elan may dispose of this product.


Other products

The intangible asset for the Pain Portfolio was written down due to supply
difficulties since its acquisition in 2001, leading to diminished selling
support from Elan as well as changed commercial expectations related to generic
competition. Naprelan and Myambutol have been written down due to the impact of
generic competition on these products in 2002 and reduced projected revenue and
profitability from these products. Frova was written down to reflect reduced
projected revenue and profitability from this product. In June 2002, Elan
elected not to exercise its purchase option to acquire certain dermatology
products from GSK. This resulted in rights to all products reverting to GSK at
the end of 2002. As a result of this decision, Elan wrote down the related
product intangible by $29.8 million to $Nil.


Autoimmune

In July 2002, Elan announced the termination of all agreements relating to the
risk-sharing arrangement with Autoimmune. The royalty obligations to Autoimmune
were terminated. The total consideration for the royalty rights was $121.0
million which, after taking account of the redemption of Elan's investment of
$38.5 million in Autoimmune, resulted in a net cash cost of $82.5 million. Elan
expensed $121.0 million as an exceptional selling, general and administration
expense arising from the acquisition of Autoimmune.


Litigation

Elan recorded a provision during 2002 of $19.0 million relating to litigation
with Schwarz, Allergan and shareholder derivative actions. For additional
information on these litigations, please refer to Note 25 to the Consolidated
Financial Statements.


(D) RESEARCH AND DEVELOPMENT

Exceptional research and development expenses were $114.7 million. These mainly
relate to product and goodwill impairments of $59.3 million and $10.6 million,
respectively, together with fixed asset write-downs of $11.6 million and
severance/relocation costs.


In September 2001, Elan acquired Delsys, for $50.0 million. Delsys was formed
in 1995 and was engaged in developing novel manufacturing technology. During
2002, Elan recorded an impairment charge for the intangible assets relating to
Delsys of $45.7 million, as under its recovery plan, Elan has decided to close
Delsys.


(E) OTHER ORDINARY ACTIVITIES

Elan recognised a gain of $77.9 million on the disposal of Athena Diagnostics
and the Abelcet business. In November 2002, Elan completed the sale of its
U.S., Canadian and any Japanese rights to Abelcet, and certain related assets,
to Enzon. Elan received a net cash payment of $360.0 million from Enzon,
representing the total consideration, after agreed price adjustments. The gain
amounted to


- --------------------------------------------------------------------------------
92


- --------------------------------------------------------------------------------

$12.7 million. In December 2002, Elan together with the other stockholders of
Elan's subsidiary, Athena Diagnostics, completed the sale of all of the
outstanding stock of Athena Diagnostics to Behrman. Elan realised net cash
proceeds of $81.8 million and a net gain of $65.2 million.

Elan has restated its U.S. GAAP financial results as of and for the fiscal year
ended 31 December 2001 to consolidate EPIL III from its date of establishment
on 15 March 2001. Under U.S. GAAP, EPIL III has historically been accounted for
by Elan as a qualifying special purpose entity and has not, therefore, been
consolidated. In addition, Elan has adjusted its previously announced unaudited
U.S. GAAP financial information as of and for the fiscal year ended 31 December
2002 to give effect to the consolidation of EPIL III and to consolidate Shelly
Bay, an entity established by Elan, from 29 June 2002 through 30 September
2002. Shelly Bay acquired certain financial assets from EPIL III on 29 June
2002. Under Irish GAAP, EPIL III has been accounted for as a consolidated
subsidiary since its date of establishment in accordance with the requirements
of FRS 5. Therefore, the 2001 restatement does not affect the Irish GAAP
financial information contained in this Annual Report and Form 20-F. For
additional information regarding the restatement and the adjustments, please
refer to Note 33 to the Consolidated Financial Statements.

In March 2001, Elan transferred a portfolio of equity and debt securities to
EPIL III, a wholly owned subsidiary of Elan. EPIL III issued $160.0 million in
aggregate principal amount of Series A Guaranteed Notes, $190.0 million in
aggregate principal amount of Series B Guaranteed Notes and $200.0 million in
aggregate principal amount of Series C Guaranteed Notes. The Series A
Guaranteed Notes matured on 29 June 2002. To fund the repayment of the notes,
on 29 June 2002 EPIL III transferred certain financial assets, consisting of
certain of the securities included in the portfolio transferred to EPIL III, to
Shelly Bay and Shelly Bay made a $148.0 million cash payment to EPIL III. EPIL
III used the proceeds from the payment by Shelly Bay, together with existing
cash of $12.0 million, to repay the Series A Guaranteed Notes. The assets
transferred by EPIL III to Shelly Bay had a carrying value under Irish GAAP of
$223.4 million.

The documents that established EPIL III required that EPIL III dispose of
financial assets in order to repay the Series A Guaranteed Notes at maturity.
The documents also mandated the order in which the assets were to be sold prior
to the maturity date for the Series A Guaranteed Notes. However, due to a
number of factors, including the inability of Elan and EPIL III to locate the
list mandating the order of disposal of the financial assets, the disposal
process was commenced and completed over the one-week period ending on 29 June
2002. Although Elan, as servicing agent for EPIL III, contracted a number of
third parties regarding their potential interest in purchasing financial assets
from EPIL III, each of those parties indicated that they would not be able to
complete a due diligence analysis of the issuers of the financial assets to be
sold, or to receive all necessary internal approvals to complete the purchase,
on a timely basis.

Therefore, in an effort to enable EPIL III to dispose of the financial assets,
Elan determined that it would be necessary to provide non-recourse credit
support to third parties who would agree to purchase financial assets from EPIL
III. Credit support was offered to a number of potential purchasers of the
financial assets. However, ultimately, only Shelly Bay possessed the ability to
complete the transaction on a timely basis.

Elan established Shelly Bay specifically for the purpose of acquiring financial
assets from EPIL III. All of the capital stock of Shelly Bay was issued to its
sole shareholder. Elan did not own any capital stock of Shelly Bay and did not
have a representative on Shelly Bay's board of directors. In addition, the sole
shareholder of Shelly Bay had no previous contact with Elan. However, as
further described below, Elan possessed all of the financial risk of the Shelly
Bay transaction. Similar to all other potential purchasers contacted by Elan,
the sole shareholder of Shelly Bay was unwilling to invest capital to acquire
the financial assets until a due diligence analysis of the issuers of the
financial assets had been completed. Therefore, the sole shareholder of Shelly
Bay made no substantive capital investment in Shelly Bay and, although Shelly
Bay possessed all of the potential financial benefits of the transaction,
neither Shelly Bay nor its sole shareholder had any financial risk in the
transaction.

Elan believed that any failure by EPIL III to dispose of financial assets prior
to 29 June 2002 could potentially adversely impact the non-consolidated
accounting status of EPIL III under U.S. GAAP and could result in defaults
under Elan's debt instruments.

Under the terms of the transaction, Shelly Bay acquired certain financial
assets from EPIL III on 29 June 2002 and made a cash payment to EPIL III of
$148.0 million. Shelly Bay financed the entire purchase price of the financial
assets, together with the funds necessary to pay interest and other costs on
the loan to its maturity date, through borrowings under a $153.0 million
non-recourse bank loan facility maturing on 30 September 2002. Elan provided a
full and unconditional guarantee to the bank to support Shelly Bay's obligation
to repay the loan and provided $153.0 million in cash collateral to the bank to
secure Elan's obligations under its guarantee. Upon the closing of the
transaction, Elan paid to Shelly Bay approximately $1 million to reimburse
Shelly Bay for the expenses expected to be incurred by it in connection with
the transaction. In addition, Elan irrevocably waived all rights of recourse
against Shelly Bay in the event that it failed to repay the bank loan at
maturity.

ELAN CORPORATION, PLC 2002 ANNUAL REPORT AND FORM 20-F                      93


NOTES RELATING TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

The cash payment made by Shelly Bay in connection with its acquisition of the
financial assets was based upon a valuation conducted by Elan. The valuation
utilised customary, widely-accepted valuation methodologies and required that
Elan make certain judgements and assumptions regarding the financial assets.
Elan did not receive any independent verification of the valuation at the time
of the transaction. In addition, EPIL III did not receive any bids for the
financial assets to be disposed of.

Upon the closing of the transaction, Shelly Bay's assets consisted solely of
the financial assets purchased from EPIL III. Under the terms of the
transaction, Shelly Bay was required to complete a due diligence analysis of
the issuers of the securities prior to 15 September 2002. Shelly Bay had the
right to either elect, on or prior to 15 September 2002, to retain the
financial assets on a long-term basis or to dispose of the financial assets
prior to 30 September 2002.

In the event that Shelly Bay elected to retain the financial assets, it was
required, within 15 days of the election, to obtain alternative financing in an
amount equal to the value, as of 29 June 2002, of the assets being retained, as
determined by an independent appraiser engaged by Shelly Bay. The net cash
proceeds received by Shelly Bay from any alternative financing were required to
be applied to repay amounts outstanding under Shelly Bay's bank loan.

In the event that Shelly Bay elected to dispose of the financial assets prior
to 30 September 2002, Shelly Bay was required to apply the net proceeds from
the dispositions to repay amounts outstanding under its bank loan. The
transaction agreements contained no limitation on the price at which any
financial asset could be sold by Shelly Bay or the party to whom any financial
asset could be sold. In addition, Elan agreed that it had no right to object to
the disposition of any financial asset, the party to whom it was disposed of or
the price obtained for the disposition.

Given the non-recourse nature of the Shelly Bay bank loan, Elan possessed all
of the financial risk of the transaction under its guarantee of the bank loan,
and the cash collateral provided by Elan to secure the guarantee, in the event
of any shortfall in the aggregate proceeds received by Shelly Bay from the
refinancing or disposition of the financial assets. Although Shelly Bay
possessed all of the potential financial benefits of the transaction, neither
Shelly Bay nor its sole shareholder had any financial risk in the transaction.

As required by the terms of the transaction, Shelly Bay engaged an independent
appraiser to value the financial assets as of 29 June 2002. The appraisal,
which was prepared in early September 2002, valued the financial assets at $8.2
million.

Shelly Bay did not elect, under the terms of the transaction, to retain any of
the financial assets and obtain alternative financing in an amount equal to the
independent appraiser's valuation. Rather, by 30 September 2002, Shelly Bay had
disposed of all of the financial assets for aggregate net proceeds of $9.3
million. A number of the financial assets were disposed of, for net proceeds of
$1.8 million, to an affiliate of Shelly Bay. The remainder of the financial
assets were sold to third parties and in open market transactions. As described
above, the transaction agreements contained no limitation on the price at which
any financial asset could be sold by Shelly Bay or the party to whom any
financial asset could be sold, including to an affiliate of Shelly Bay. In
addition, Elan agreed that it had no right to object to the disposition of any
financial asset, the party to whom it was disposed of or the price obtained for
the disposition.

As a result of the disposition of the financial assets by Shelly Bay for
aggregate net proceeds of $9.3 million, on 30 September 2002, Elan made a cash
payment of $141.6 million to satisfy its obligation under its guarantee. Under
the terms of the transaction agreements, Elan has no further obligation under
the guarantee and has no recourse to Shelly Bay or to its sole shareholder
arising from Elan's payment under the guarantee. The loss on the sale of the
securities was $217.0 million under Irish GAAP including the $141.6 million
under the guarantee.


(F) NET INTEREST

Exceptional net interest and other expenses were $1,004.0 million.

This includes a charge of $1,045.9 million relating to investments in Elan's
investment portfolio, including the investments held by EPIL II and EPIL III.
The financial markets for emerging biotechnology, drug delivery and
pharmaceutical companies declined significantly during 2002. The investment
impairment charge mainly reflects this significant decline in the financial
markets and also the impact of weak financial markets on the ability of
emerging biotechnology, drug delivery and pharmaceutical companies to raise
finance. The charge also includes impairments relating to investments in
business ventures and business venture parents. The investment impairments
comprise $215.4 million, $575.4 million and $255.1 million in relation to
quoted investments, unquoted investments and loans, and securitised investments
respectively.

Offsetting this charge was a net gain of $37.7 million on the repurchase of
$318.6 million in principal amount at maturity of LYONs. These LYONs, having an
accreted value of $190.1 million at the date of purchase, were purchased at an
aggregate cost of $149.8 million, resulting in the net gain of $37.7 million
after related costs. For further information regarding the LYONs, please refer
to Note 16 to the Consolidated Financial Statements.

2001

In 2001, Elan incurred net exceptional charges of $964.6 million. These
revenues and costs have been included under the statutory format headings to
which they relate analysed as follows:



                                                                              SELLING,      RESEARCH

- --------------------------------------------------------------------------------------------------------------------------


(A) REVENUE

Exceptional revenue in 2001 primarily relates to product rationalisation
revenue of $231.4 million.


(B) COST OF SALES

The exceptional cost of sales is primarily comprised of $15.6 million relating
to product rationalisation revenue.


(C) SELLING, GENERAL AND ADMINISTRATIVE

Exceptional selling, general and administrative expenses were $1,084.2 million.
$1,009.8 million of the exceptional charges relate to impairment charges
arising on write-downs of intangible assets. Impairment charges to acquired IP
arising from the acquisitions of Neurex and Sano were $500.0 million and $285.2
million, respectively. Impairment charges to patents and licences arising on
write-downs of the product intangibles for Naprelan, Ceclor CD and Myambutol
were $81.0 million, $94.2 million and $44.4 million, respectively. Other
impairments to patents and licences amounted to $5.0 million. Other exceptional
selling, general and administrative expenses were $74.4 million. These mainly
relate to severance, integration, relocation and similar costs and asset
write-downs arising from the integration of Elan's U.S. Biopharmaceuticals
business.

Elan acquired Neurex in August 1998 for $810.0 million. Neurex was developing
Prialt. The purchase price was primarily allocated to acquired IP. In 2001,
Elan wrote down acquired IP arising from the acquisition of Neurex by $500.0
million. This write-down was due to delays in the product launch schedule and
reduced revenue projections for Prialt.

Elan acquired Sano in February 1998 for $434.6 million. Sano was developing
transdermal drug delivery products. The purchase price was primarily allocated
to acquired IP. In 2001, Elan wrote down acquired IP arising from the
acquisition of Sano by $285.2 million. The write-down was due to reduced
revenue projections from products under development and to Elan's decision to
focus its research and development efforts in other areas.

Ceclor CD and Myambutol were written down due to the impact of generic
competition on these products during 2001. Generic versions of each of these
products were approved and launched in 2001, which reduced projected revenues
and profitability from these products. Revenue from Ceclor CD declined by $26.0
million in 2001, from $39.4 million in 2000 to $13.4 million in 2001. Naprelan
was written down due to lower than forecasted revenues in 2001 and reduced
projected revenue and profitability from this product. The level of promotional
support for a product can have a significant impact on the level of revenue
generated from that product. Elan does not expect to provide any significant
promotional support for Naprelan in the future and this has been reflected in
the projections for this product. Revenue from Naprelan declined by $33.6
million in 2001, from $41.8 million in 2000 to $8.2 million in 2001.

(D) RESEARCH AND DEVELOPMENT

Exceptional research and development expenses were $78.6 million in 2001. These
mainly relate to severance, integration and similar costs and asset write-downs
arising from the re-organisation, closure or scaling back of various drug
delivery programmes and sites. Also included were costs of certain research
programmes that Elan does not intend to complete. These were the estimated
costs incurred pending closure or sale.


(E) NET INTEREST

Exceptional net interest and other expenses were $6.8 million in 2001. These
mainly relate to costs associated with the redemption in March 2001 of the
4.75% Exchangeable Notes of Athena Neurosciences.


2000

In 2000, Elan incurred exceptional charges of $113.6 million. These costs have
been included under the statutory format headings to which they relate analysed
as follows:



                                                                  SELLING,      RESEARCH        OTHER

In November 2000, the FDA requested that the pharmaceutical industry
voluntarily cease the distribution and marketing of products containing PPA.
The Company ceased shipment of the products containing PPA and withdrew them
from customers' warehouses and retail shelves. In connection with the
termination of this activity, Elan incurred an exceptional charge of $35.6
million, primarily for product returns and the write-off of inventory and
product intangible assets. Elan incurred charges of $0.6 million arising from
the acquisition of Dura. Elan incurred charges of $10.4 million arising from
the termination of certain research and development projects and charges of
$21.4 million relating to the write-down of certain intangible assets arising
from a change in focus of Elan's business. Elan incurred charges of $22.2
million arising from a rationalisation of its Biopharmaceuticals business unit,
primarily relating to severance costs and the transfer of most pharmaceutical
distribution activities and certain inventory to one location in the United
States, resulting in exceptional inventory write-offs. The remaining
exceptional charges primarily relate to asset write-downs.


4 NEURALAB

From January 1998, Elan was a party to a development and licence agreement (the
"Neuralab Development Contract") and a services agreement with Neuralab, to
identify therapeutic compounds for use in the treatment of AD. In January 1998,
a private placement of 1,250,000 units was completed. The net proceeds received
by Neuralab from the sale of the units was $47.0 million, substantially all of
which was used to reimburse Elan under the Neuralab Development Contract. The
Neuralab Development Contract provided for Elan to conduct clinical development
and final product development in respect of designated products. The Neuralab
Services Agreement provided for Elan to provide management and administrative
services to Neuralab. Revenue received by Elan in 2000 pursuant to these
agreements was $1.8 million. On 31 January 2000, Elan purchased all of the
outstanding common shares of Neuralab for approximately $76.4 million in cash.

Current tax, including Irish corporation tax and foreign taxes, is provided on
the Group's taxable profits, at amounts expected to be paid (or recovered)
using the tax rates and laws that have been enacted or substantially enacted by
the balance sheet date. In each of the three years ended 31 December 2002, 31
December 2001 and 31 December 2000, substantially all of Elan's income in
Ireland was exempt from taxation by virtue of relief granted on income derived
from patents or due to tax losses incurred. The tax charge of $19.8 million for
2002 reflected tax at standard rates in the jurisdictions in which Elan
operates, income derived from Irish patents, which is exempt from tax, foreign
withholding tax and the availability of tax losses.

Reflecting the exempt nature of Irish income and the availability of tax losses
in Ireland and foreign operations, there was no deferred tax expense for the
above years.

Except as outlined below, deferred taxation is recognised in respect of all
timing differences that have originated but not reversed at the balance sheet
date. No taxes have been provided for the unremitted and untaxed earnings of
the Group companies overseas as these are, in the main, considered permanently
employed in the business of these companies. Cumulative unremitted earnings of
overseas subsidiaries and related undertakings totalled approximately $646
million at 31 December 2002. Deferred tax assets are recognised to the extent
that, on the basis of available evidence, it is regarded as more likely than
not that there will be suitable taxable profits from which the future reversal
of the underlying timing differences can be deducted. The calculation of the
deferred taxation asset or liability is based on the taxation rates that are
expected to apply in the periods in which the timing differences are expected
to reverse based on tax rates and laws that have been enacted or substantially
enacted at the balance sheet date.

The U.S. Internal Revenue Service has completed an audit of Dura and its
subsidiaries for the 1997 to 2000 tax years, which pre-date the acquisition of
Dura by the Company. As adequate amounts for tax and related interest had been
provided, no additional tax was charged as a result of this examination.

9 EARNINGS PER SHARE

Basic earnings per share is computed by dividing the net profit or loss for the
period available to ordinary shareholders by the sum of the weighted average
number of Ordinary Shares in issue and ranking for dividends during the period.
Diluted earnings per share is computed by dividing the net profit or loss for
the period by the weighted average number of Ordinary Shares in issue, adjusted
for the effect of all dilutive potential Ordinary Shares that were outstanding
during the period.

The following table sets forth the computation for basic and diluted earnings
per share ("EPS"):

At 31 December 2002, the main components of the carrying value of patents and
licences were $331.3 million for Sonata, $330.1 million for Maxipime/Azactam,
$117.7 million for the AD intellectual property and $94.3 million for Prialt.

At 31 December 2002, the carrying values of acquired IP relating to the
acquisitions of Neurex, NanoSystems LLC ("NanoSystems"), Axogen, Carnrick and
Sano were $286.9 million, $49.7 million, $48.0 million, $15.8 million and $9.3
million, respectively.

At 31 December 2002, the main components of the carrying value of goodwill were
$123.1 million for Dura, $86.8 million for Liposome, $48.3 million for
Nanosystems and $30.7 million for Carnrick.

Elan acquires companies engaged in research and development activities as it
expects that the intellectual property created through the acquired companies'
research and development processes may result in a future earnings stream.
Acquired IP represents that portion of the purchase price that Elan attributes
to the value of the research and development activity undertaken by the
acquired research and development company prior to acquisition. It is not a
payment for research and development but rather for the value created through
previous research and development.

Acquired IP is capitalised as an intangible asset and is amortised over its
useful economic life. The useful economic life is the period over which Elan
expects to derive economic benefits. Acquired IP rights of $296.2 million
(relating to Neurex and Sano) were not amortised in 2002, as the useful
economic life of those rights had not commenced. Upon commencement of its
useful economic life, acquired IP will be amortised on a straight-line basis
over the period that economic benefits are expected to accrue, which is not
expected to exceed 20 years. In the case of each acquisition, the useful
economic life of acquired IP commences upon the generation of product revenue
from that acquired IP. Pharmaceutical products cannot be marketed until the
successful completion of research and development and the receipt of regulatory
approval to market. Under U.S. GAAP, the corresponding amounts were expensed
immediately upon acquisition as IPR&D costs.

In accordance with the requirements of FRS 11, "Impairment of Fixed Assets and
Goodwill" ("FRS 11"), Elan conducts an impairment review of acquired IP rights
at least annually, prior to the commencement of amortisation, to assess whether
its carrying value is supported.

million and a net equity investment of $11.9 million. Amarin repaid $19.9
million of loans and interest in January 2003.

Elan and Amarin agreed to amend their contractual arrangements in January 2003

the 2003 amendments, please refer to Note 27 to the Consolidated Financial
Statements.

3.5% CONVERTIBLE NOTES

As part of the acquisition of Dura, Elan assumed $287.5 million in aggregate
principal amount of 3.5% Convertible Notes due 15 July 2002. The 3.5%
Convertible Notes contained a change in control provision that became effective
upon Elan's acquisition of Dura. Under this provision, holders of the 3.5%
Convertible Notes had the right, for a period of 40 days after the consummation
of the acquisition, to require Elan to repurchase their notes for their face
value plus accrued interest through the date of purchase. In December 2000,
Elan redeemed $224.9 million principal amount of the 3.5% Convertible Notes
under this provision. The remaining 3.5% Convertible Notes were repaid in July
2002.

Interest charged in the year ending 31 December 2002 amounted to $1.1 million
(2001: $2.2 million, 2000: $1.2 million). The liability outstanding at 31
December 2002, net of financing costs, was $Nil, (2001: $62.4 million) with
interest accrued of $Nil (2001: $1.0 million).


EPIL III NOTES

In March 2001, the Company transferred a portfolio of equity and debt
securities to a special purpose entity, EPIL III, a wholly owned subsidiary of
the Company. EPIL III issued $200.0 million in aggregate principal amount of
the Series C Guaranteed Notes in a private placement to a group of financial
institutions. In addition, EPIL III issued $160.0 million in aggregate
principal amount of the Series A Guaranteed Notes and $190.0 million of the
Series B Guaranteed Notes, in exchange for all outstanding 8.43% Guaranteed
Notes issued in June 1999 by EPIL. The Series A Guaranteed Notes were, and the
Series B Guaranteed Notes and Series C Guaranteed Notes are, fully and
unconditionally guaranteed on a subordinated basis by Elan. The Series A
Guaranteed Notes bore interest at the rate of 8.43% per annum. The Series B
Guaranteed Notes bear interest at the rate of 8.43% per annum through June 2002
and 7.72% per annum thereafter. The Series C Guaranteed Notes bear interest at
the rate of 7.62% per annum.

In 2001, EPIL III paid cash of $106.0 million to the Company and also exchanged
the EPIL III Series A and Series B Guaranteed Notes for all outstanding 8.43%
Guaranteed Notes as consideration for the portfolio of investments transferred
to it. Other than these payments and a payment of $0.8 million (2001: $0.6
million, 2000: $Nil) for administration services, there were no other cash
flows between EPIL III and the Company in 2002, 2001 or 2000. The remaining
investments and cash in EPIL III are held as security against the EPIL III
Series B Guaranteed Notes and the Series C Guaranteed Notes. These assets are
not available for distribution outside EPIL III. The investments and cash had a
fair value of $142.4 million, and a carrying value of $131.5 million, at 31
December 2002. The Series B Guaranteed Notes and the Series C Guaranteed Notes
are guaranteed on a subordinated basis by Elan and, consequently, in accordance
with the provisions of FRS 5, the Series B Guaranteed Notes and the Series C
Guaranteed Notes, investments and cash are included separately in the Company's
consolidated balance sheet. Issue costs associated with the financing of the
EPIL III Notes amounted to $6.1 million.

NOTES RELATING TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

In June 2002, EPIL III disposed of securitised investments in order to repay
the $160.0 million in the aggregate principal amount of its Series A Guaranteed
Notes which matured on 29 June 2002.

For additional information relating to the disposal of financial assets by EPIL
III, please refer to Note 3 and Note 33 to the Consolidated Financial
Statements.

Interest charged on the EPIL III notes in 2002 amounted to $37.2 million (2001:
$35.4 million, 2000: $Nil). The liability outstanding at 31 December 2002, net
of financing costs, was $387.5 million (2001: $545.5 million) with interest
accrued of $0.2 million (2001: $9.4 million).


3.25% LYONs

In December 1998 Elan Finance issued, in a private placement and at a
substantial discount, LYONs due 2018 in the principal amount of $1,643.5
million at maturity. The issue price of the LYONs was $524.78 per $1,000
principal amount at maturity and the gross proceeds to the Company amounted to
$862.5 million. The expenses associated with the transaction amounted to $23.1
million. The LYONs are exchangeable at any time at the option of the holder
into 13.75 Elan ADSs per each $1,000 principal amount at maturity. The
securities are redeemable for cash at any time, at the option of the Company,
on or after 14 December 2003. Holders of the LYONs may require Elan to purchase
all or any portion of their LYONs on 14 December 2003, 14 December 2008 and 14
December 2013 at a purchase price equal to the issue price plus all accrued
original issue discount up to the purchase date. Elan may, at its option, elect
to pay the purchase price for the LYONs in cash, by the delivery of ADSs, at
then existing market prices, or any combination of cash and ADSs. Elan's right
to pay the purchase price for the LYONs by delivering ADSs is subject to
certain conditions, including the registration of the ADSs to be delivered
under the Securities Act of 1933 and the listing of those ADSs on the NYSE. In
addition, under the Companies (Amendment) Act, 1983, and a related shareholder
resolution passed on 18 March 2003, the number of ADSs that Elan may issue in
payment for the LYONs will be limited to a maximum of 120 million ADSs unless
Elan seeks and receives an additional resolution from its shareholders
authorising it to issue additional ADSs.

In December 2002, Elan repurchased $318.6 million in principal amount at
maturity of LYONs (representing approximately 19% of the originally issued
LYONs) in separate privately negotiated purchases. These LYONs, having an
accreted value of $190.1 million at the dates of acquisition, were purchased at
an aggregate cost of $149.8 million, resulting in a net gain of $37.7 million
after related costs at the dates of acquisition. This was a discount of
approximately 24% to the accreted value of such LYONs at 14 December 2003 of
$196.5 million.

The original issue discount charged to income in the year to 31 December 2002
amounted to $31.0 million (2001: $30.2 million, 2000: $29.2 million). At 31
December 2002, the liability represented a price of $597.97 per $1,000
principal amount at maturity.

The liability outstanding at 31 December 2002, net of financing costs of $13.3
million (2001: $19.6 million), was $682.0 million (2001: $842.9 million) with
interest accrued of $97.0 million (2001: $89.0 million). Inclusive of financing
costs, the accreted value of the LYONs at 31 December 2002 was $792.3 million
(2001: $951.5 million).

Through 3 June 2003, Elan repurchased an additional $523.7 million in principal
amount at maturity of the LYONs (representing approximately 32% of the
originally issued LYONs) in separate privately negotiated purchases. The
aggregate cost was $310.3 million. This was a discount of approximately 4% to
the accreted value of such LYONs at 14 December 2003 of $322.9 million. After
taking account of all repurchases up to 3 June 2003, the remaining LYONs have
an accreted value at 14 December 2003 of $494.0 million. Elan may purchase
additional LYONs in the future and any such purchases may be material.


EPIL II NOTES

In June 2000, the Company transferred a portfolio of equity and debt securities
to a special purpose entity, EPIL II, a wholly owned subsidiary of the Company.
On 28 June 2000, EPIL II issued $450.0 million in aggregate principal amount of
the EPIL II Notes, in a private placement to a group of financial institutions.
EPIL II paid cash of $340.0 million to the Company for the portfolio of
investments transferred to it. Other than this payment and a payment of $0.8
million (2001: $0.8 million; 2000: $0.4 million) for administration services,
there were no other cash flows between EPIL II and the Company in 2002, 2001 or
2000. The investments and cash in EPIL II are held as security against the EPIL
II Notes. These assets are not available for distribution outside EPIL II. The
investments and cash had a fair value of $151.7 million, and a carrying value
of $146.8 million, at 31 December 2002. The EPIL II Notes are guaranteed on a
subordinated basis by Elan and, consequently, in accordance with the provisions
of FRS 5, the EPIL II Notes and the investments are both

- --------------------------------------------------------------------------------

included separately in the Company's consolidated balance sheet. The EPIL II
Notes bear interest at the rate of 9.56% per annum, payable in cash. Issue
costs associated with the financing amounted to $5.9 million.

Interest charged in 2002 amounted to $43.0 million (2001: $43.0 million; 2000:
$21.9 million). The liability outstanding at 31 December 2002, net of financing
costs, was $449.0 million (2001: $447.1 million) with interest accrued of $0.4
million (2001: $0.4 million).


7.25% SENIOR NOTES

In February 2001, Athena Finance, an indirect wholly owned subsidiary of Elan,
issued $650.0 million in aggregate principal amount of the 7.25% Senior Notes
due 2008 at a discount of $2.5 million. The 7.25% Senior Notes are senior,
unsecured obligations of Athena Finance and are fully and unconditionally
guaranteed on a senior unsecured basis by Elan. Issue costs associated with the
financing amounted to $8.3 million.

Interest is paid in cash semi-annually. Interest charged in the year ending 31
December 2002 amounted to $47.1 million (2001: $40.3 million, 2000: $Nil). The
liability outstanding at 31 December 2002, net of financing costs, was $643.9
million (2001: $642.7 million) with interest accrued of $16.7 million (2001:
$16.7 million).

On 14 January 2002, Elan entered into an interest rate swap to convert its
fixed rate interest obligations for $100.0 million of the 7.25% Senior Notes to
variable rate interest obligations. The swap had an unrecorded fair value gain
of $8.1 million at 31 December 2002.


8.43% GUARANTEED NOTES

In June 1999, the Company transferred a portfolio of equity and debt securities
to a special purpose entity, EPIL, a wholly owned subsidiary of the Company. On
29 June 1999, EPIL issued $350.0 million in aggregate principal amount of the
8.43% Guaranteed Notes, in a private placement to a group of financial
institutions. EPIL paid cash of $285.0 million to the Company for the portfolio
of investments transferred to it. The investments and cash in EPIL were held as
security against the 8.43% Guaranteed Notes. The 8.43% Guaranteed Notes were
guaranteed on a subordinated basis by Elan. These assets were not available for
distribution outside EPIL. The 8.43% Guaranteed Notes bore interest at the rate
of 8.43% per annum.

Interest charged in 2002 amounted to $Nil (2001: $6.1 million, 2000: $29.7
million).

In March 2001, the 8.43% Guaranteed Notes were cancelled in connection with the
establishment of EPIL III and as a result of the exchange by EPIL III of its
Series A and B Guaranteed Notes for all outstanding 8.43% Guaranteed Notes. The
restrictions on EPIL's ability to distribute its assets have been terminated.


COVENANTS

The agreements governing certain of Elan's outstanding indebtedness contain
various restrictive covenants that restrict the Group's ability to, among other
things, incur additional indebtedness (including intercompany indebtedness),
create liens and other encumbrances, enter into transactions with related
parties, sell or otherwise dispose of assets and merge or consolidate with
another entity. In addition, some of these agreements require Elan to maintain
certain financial ratios. Elan does not currently, and does not expect in the
foreseeable future to have the ability to incur any additional indebtedness
under certain of these covenants.

As a result of Elan's failure to timely complete and file with the SEC Elan's
Annual Report on Form 20-F for its fiscal year ended 31 December 2002, on 30
June 2003, Elan defaulted under certain covenants contained in the agreements
governing the EPIL II Notes and the Series B and Series C Guaranteed Notes
issued by EPIL III. The covenants required that Elan provide to each of the
holders of such notes Elan's audited consolidated financial statements,
together with an officer's certificate relating thereto, on or prior to 29 June
2003. On 15 July 2003, Elan also defaulted under a covenant contained in the
indenture governing the 7.25% Senior Notes that required Elan to file its 2002
Annual Report on Form 20-F with the SEC on or prior to 15 July 2003.

Commencing on 29 July 2003, Elan received a series of separate agreements from
a majority of the holders of the EPIL II Notes and the holders of the Series B
and Series C Guaranteed Notes waiving compliance by Elan with the applicable

BANK LOANS AND SHORT TERM DEBT

On 8 February 1999, Elan entered into an agreement with a syndicate of banks,
mainly European lending institutions, for a $325.0 million senior unsecured
revolving credit facility. At 31 December 2001, $325.0 million of this facility
was drawn down. On 11 July 2002, Elan repaid in full and terminated the
revolving credit facility.


PRODUCT ACQUISITIONS AND ALLIANCES

At 31 December 2002, Elan included in creditors $482.2 million relating to
future payments and/or future potential payments on products. Of the $482.2
million, $227.2 million was owing at 31 December 2002 and $255.0 million was
potentially payable, contingent on future events. Elan is a party to certain
product acquisition or alliance agreements that contain staged or option
payments which may be uncertain in amount, which may be paid at Elan's
discretion, such as upon the exercise of an option to acquire the product, or
which must be paid upon the occurrence of future events, such as the attainment
of pre-determined product revenue targets or other milestones. Elan has accrued
$277.6 million within creditors (within one year), including $130.7 million for
Maxipime/Azactam, $114.7 million for Sonata and $28.3 million for the Pain
Portfolio, and $204.6 million within creditors (after one year), including
$146.0 million for Sonata and $49.1 million for the Pain Portfolio.

At 31 December 2001, Elan included in creditors $900.4 million relating to
future payments and/or future potential payments on products. The reduction of
$418.2 million from December 2001 primarily reflects product payments made
during the year of $234.6 million and contingent product payments avoided of
$224.3 million. The contingent product payments avoided relate primarily to
Elan's decision not to acquire the dermatology products from GSK during 2002.

In 2002, Elan divested its dermatology business and, as a result, did not
exercise the option to complete the purchase of the dermatology product line
from GSK. As such, the related contingency payments are no longer payable at 31
December 2002.

On 12 June 2003, Elan sold its primary care franchise, including its rights to
Sonata, to King. For additional information, please refer to Note 29 to the
Consolidated Financial Statements.

22 FINANCIAL INSTRUMENTS

The Company uses derivative financial instruments to reduce exposure to market
risk resulting from fluctuations in foreign exchange rates and interest rates.
The Company does not enter into derivative financial instruments for trading or
speculative purposes.

Derivative instruments are contractual agreements whose value reflects price
movements in an underlying asset or liability. The Company uses derivatives,
where appropriate, to generate the desired effective profile of currency and
interest rate risk.

The main risks arising from the use of financial instruments are market rate
risk and liquidity risk. Market rate risk is defined as the exposure of Elan's
financial condition to adverse movements in interest and foreign exchange
risks. The Company only enters into contracts with parties that have at least
an "A" or equivalent credit rating. The counterparties to these contracts are
major financial institutions. Management believes that the risk of any net loss
is remote and would not be material to the Company.

NOTES RELATING TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

Short term debtors and creditors have been excluded from all numerical
disclosures below excluding the currency rate risk analysis. As explained in
Note 1 to the Consolidated Financial Statements, the financial statements are
prepared in U.S. dollars and, therefore, the Company is exposed to foreign
exchange risks related to costs incurred and revenues earned in currencies
other than U.S. dollars.


A INTEREST RATE RISK

The interest rate risk profile of Elan's financial liabilities was as follows:

Variable interest rates on cash and liquid resources are generally based on the
appropriate Euro Interbank Offered Rate, London Interbank Bid Rate and bank
rates dependent on principal amounts on deposit.


B CURRENCY RATE RISK

The Group has exposure to various reporting currencies due to the international
nature of its operations. Gains and losses arising from this currency exposure
are recognised in the Consolidated Statement of Total Recognised Gains and
Losses.

The table below shows Elan's currency exposure. Such exposure comprises the
monetary assets and monetary liabilities of Elan that are not denominated in
the operating currency of the operating unit involved. At 31 December 2002 and
2001, respectively, these exposures were as follows:

contracts and other derivatives entered into to manage these currency
exposures.


C FAIR VALUES

Fair value is the amount at which a financial instrument could be exchanged in
an arm's-length transaction between informed and willing parties, other than a
forced or liquidation sale.

The following methods and assumptions were used to estimate the fair value of
each material class of financial instrument:

Financial assets--the fair values of financial assets have been estimated for
quoted equity securities utilising quoted market prices, for debt securities by
methods including utilising current market interest rates for loans with
similar risk and duration profile and for material unquoted equity investments
generally by the most recent private financing prices, discounted projected
future cash flows and option valuation models. The fair values of marketable
securities, including interest rate futures, have been estimated based on
quotes obtained from brokers for these and similar instruments.

Cash, liquid resources, current bank loans and overdrafts--carrying amount
approximates fair value due to the short term nature of these instruments.

3.25% Zero Coupon Subordinated Exchangeable Notes (LYONs), 3.5% Convertible
Subordinated Notes and 7.25% Senior Notes--the fair values have been assessed
based on the quoted market price.

EPIL II Notes and EPIL III Notes--the fair values have been assumed to be the
carrying values. It is possible, however, that the fair values are less than
the carrying values given the deterioration in the credit rating of these
instruments during 2002.

The carrying value of financial instruments below have been stated before
financing costs and include accrued interest.

E DERIVATIVE INSTRUMENTS

Under Elan's accounting policy, foreign currency options and forward exchange
contracts are valued at year-end exchange rates. Consequently, changes in fair
value attributable to movements in exchange rates are recognised in the profit
and loss account.

At 31 December 2002, Elan had entered into a number of forward foreign exchange
contracts and foreign currency options at various rates of exchange in the
normal course of business. The nominal value of forward foreign exchange
contracts to sell Japanese Yen for U.S. dollars at that date was $7.9 million
(2001: $30.2 million) and these contracts had a fair value loss of $0.4 million
(2001: $5.8 million gain). These contracts expire on various dates up to and
including September 2003.

The nominal value of forward foreign exchange contracts to sell U.S. dollars
for Euro at 31 December 2002 was $39.8 million (2001: $138.0 million) and these
contracts had a fair value gain of $5.0 million (2001: $0.7 million loss).
These contracts expire on various dates up to and including October 2003.

The nominal value of forward foreign exchange contracts to sell U.S. dollars
for Sterling at 31 December 2002 was $4.6 million (2001: $Nil) and these
contracts had a fair value gain of $0.2 million (2001: $Nil). These contracts
had all expired by June 2003.

- --------------------------------------------------------------------------------
116


- --------------------------------------------------------------------------------

The nominal value of currency options to sell U.S. dollars for Euro at 31
December 2002 amounted to $24.0 million (2001: $42.0 million) and these options
had a fair value gain of $3.0 million (2001: $0.1 million loss). These options
expire on various dates up to and including December 2003.

In February 2001, Elan raised $650.0 million of 7.25% Senior Notes due 2008. On
14 January 2002, Elan entered into an interest rate swap to convert its fixed
rate interest obligations for $100.0 million of the 7.25% Senior Notes to
variable rate interest obligations. The swap had an unrecorded fair value gain
of $8.1 million at 31 December 2002.

F SENSITIVITY ANALYSIS

A sensitivity analysis of the market value of Elan's financial instruments to
hypothetical changes in applicable market rates at 31 December 2002 indicated
that their effect would not be material. The range scenario included was based
on Elan's expectation of what would be reasonable on a 12 month time frame and
involved a 10% movement in foreign exchange rates and a 1% movement in interest
rates. The effect of such an adverse movement in rates would be a decrease in
income of approximately $12 million.

Elan is exposed to equity price risks primarily on equity investments in quoted
companies. At 31 December 2002, quoted securities had a fair value of $165.5
million and had a cost of $160.1 million. These investments are primarily in
emerging pharmaceutical and biotechnology companies. A 10% adverse change in
equity prices would result in an approximate $17 million decrease in the fair
value of these quoted securities.

On 19 December 2001, Elan sold approximately 20% of Athena Diagnostics for cash
in a private placement, resulting in $41.9 million of gross proceeds to Elan,
before accrued costs. On 31 December 2002, Elan together with the other
stockholders of Elan's subsidiary, Athena Diagnostics, completed the sale of
all of the outstanding stock of Athena Diagnostics to Behrman. Elan realised
net cash proceeds of $81.8 million and a net gain of $65.2 million after
adjusting for net assets sold.

Details of the acquisition of subsidiary undertakings are given below:


2001


DELSYS

In September 2001, Elan acquired Delsys. The total consideration amounted to
$50.0 million. This included cash paid together with the cost of Elan's
existing investment in the Company. Net liabilities assumed amounted to $1.2
million. Delsys was formed in 1995 and was engaged in developing novel
manufacturing technology. The purchase of Delsys was accounted for as an
acquisition. At the date of acquisition, the fair value adjustment related to
technologies of Delsys, which are separable from the business, was $51.2
million. During 2002, Elan recorded an impairment charge of $45.7 million as
under its recovery plan, Elan has decided to close Delsys.


2000


DURA

On 9 November 2000, Elan acquired Dura through an exchange of 0.6715 of an Elan
Ordinary Share for each outstanding share of Dura common stock, resulting in
the issuance of 30.6 million Ordinary Shares. Options and warrants granted by
Dura prior to the acquisition date were converted into options and warrants to
acquire approximately 5.5 million Ordinary Shares. The total consideration,
including expenses, amounted to $1,590.7 million. The purchase of Dura was

adjustment related to patents and current products of Dura valued at the date
of acquisition, which are separable from the business, was $29.9 million,
offset, in part, by a deferred tax adjustment of $18.4 million and the
write-off of financing costs of $2.7 million. Patents and licences arising on
acquisition are being amortised over ten years. Goodwill arising on acquisition
amounted to $1,111.7 million. In accordance with FRS 11, Elan performed its
annual impairment review of goodwill during 2002. As a result of this review,
Elan recorded an impairment charge of $854.9 million during 2002. For
additional information, please refer to Note 3 to the Consolidated Financial
Statements.


LIPOSOME

On 12 May 2000, Elan acquired Liposome. In connection with the acquisition,
each outstanding share of Liposome common stock was exchanged for 0.385 of an
Elan Ordinary Share, resulting in the issuance of approximately 15.6 million
Ordinary Shares, and one contingent value right ("CVR") for each Liposome
share, option and warrant representing contingent consideration. Options and
warrants granted by Liposome prior to the acquisition date were converted into
options and warrants to acquire approximately 1.9 million Ordinary Shares. The
agreement governing the CVRs provided for a cash payment by Elan to the holders
of the CVRs of up to $98.0 million less certain costs incurred by Elan, with
$54.0 million contingent on Myocet receiving marketing and pricing approval in
certain countries of the EU, and $44.0 million contingent on Myocet reaching
certain sales milestones outside the United States. In March 2001, Elan
completed all milestones necessary for the European launch of Myocet. As a
result, on 9 April 2001, Elan made an initial cash payment of $54.0 million
less costs to the holders of the CVRs. On 31 March 2003, the agreement
governing the CVRs terminated in accordance with its terms. As Myocet did not
achieve the required sales milestones, the contingent payment of $44.0 million
was not made. Elan will not be required to make any additional payments to the
holders of the CVRs. Myocet is a proprietary liposomal formulation of
doxorubicin which has been developed for the treatment of metastatic breast
cancer.

The purchase of Liposome was accounted for as an acquisition. The total
consideration of $731.8 million included the milestone payment of $54.0
million. At the date of acquisition, the fair value adjustment related to
patents, current products and development projects of Liposome, which are
separable from the business, were valued at $263.1 million. Patents and
licences arising on acquisition are being amortised over twenty years. Goodwill
arising on acquisition was $371.3 million. Under its recovery plan, Elan
disposed of its U.S., Canadian and any Japanese rights to Abelcet, and certain
related assets, in 2002, and allocated $119.0 million of goodwill to the sale
of the Abelcet business based on the estimated relative fair value of the
Abelcet rights disposed to the retained rights. Additionally, in 2002, Elan
wrote down the remaining goodwill arising from the acquisition of Liposome by
$111.8 million. Goodwill is being amortised over a period of twenty years. For
additional information, please refer to Note 3 to the Consolidated Financial
Statements.


NEURALAB

On 31 January 2000, Elan completed the acquisition of Neuralab pursuant to a
purchase option to purchase all, but not less than all, of the outstanding
common shares of Neuralab. The purchase price, paid in cash, amounted to $76.4
million. Net liabilities assumed amounted to $9.7 million. Neuralab was formed
in August 1997 and is engaged in research and development programs in the field
of AD. The purchase of Neuralab has been accounted for as an acquisition. The
intangibles arising on acquisition of $86.1 million are being amortised over
twenty years.


QUADRANT

Elan acquired Quadrant in December 2000 for $86.0 million. Quadrant was a drug
delivery company with proprietary formulation technology applicable to
pulmonary, oral and parenteral routes of administration. The purchase price was
primarily allocated to goodwill. In 2002, Elan wrote down goodwill arising from
the acquisition of Quadrant by $78.2 million to $Nil, as under its recovery
plan, Elan decided to dispose of or close the Quadrant business. This business
was sold to a company managed by former employees of the business in July 2003.


OTHER

Elan acquired Segix Italia, S.p.A. on 20 April 2000 and Vita Elan Pharma, S.A.
on 29 June 2000. The total consideration paid was $21.8 million. The purchases
have been accounted for as acquisitions and resulted in goodwill of $34.3
million, which is being amortised over periods of twenty years.

million and subsequently leased the plant and equipment back under six year
leases.

In prior years, Elan disposed of plant and equipment and subsequently leased
the plant and equipment back and also entered into an arrangement with a third
party bank, the substance of which allows the Company to require a net
settlement of its obligations under the leases. The related assets and
liabilities of these previous sale and leaseback transactions have been offset
in the financial statements in the amount of $56.2 million at 31 December 2002
(2001: $50.3 million).

RISK-SHARING ARRANGEMENTS


Pharma Marketing

In June 2000, Elan disposed of royalty rights on certain products and
development projects to Pharma Marketing. Pharma Marketing completed a private
placement of its common shares to a group of institutional investors, resulting
in gross proceeds of $275.0 million. Elan holds no investment in Pharma
Marketing and has no representative on its board of directors. Concurrent with
the private placement, Pharma Marketing entered into a Program Agreement with
Elan. The Program Agreement, which substantially regulates the relationship
between Elan and Pharma Marketing, represents a risk-sharing arrangement
between Elan and Pharma Marketing. Under the terms of the Program Agreement,
Pharma Marketing acquired certain royalty rights to each of the following
products for the designated indications (including any other product which
contains the active ingredient included in such product for any other
designation): (i) Frova, for the treatment of migraine; (ii) Myobloc, for the
treatment of cervical dystonia; (iii) Prialt, for the treatment of acute pain
and severe chronic pain; (iv) Zanaflex, for the treatment of spasticity and
painful spasm; and (v) Zonegran, for the treatment of epilepsy. Pharma
Marketing agreed to make payments to Elan in amounts equal to expenditures made
by Elan in connection with the commercialisation and development of these
products, subject to certain limitations. These payments were made on a
quarterly basis based on the actual costs incurred by Elan. Elan did not
receive a margin on these payments.

Elan's revenue from Pharma Marketing was $31.3 million for 2002, consisting of
$24.0 million for commercialisation expenditures, which has been recorded as
product revenue, and $7.3 million for development expenditures, which has been
recorded as contract revenue. Pursuant to the Program Agreement, Pharma
Marketing utilised all of its available funding by mid-2002. Elan will not
receive any future revenue from Pharma Marketing. Elan's revenue from Pharma
Marketing was $189.8 million for 2001, consisting of $141.8 million for
commercialisation expenditures, and $48.0 million for development expenditures.
In 2002, the royalty rate on net sales of all designated products was 15.79% on
the first $122.9 million of net sales and 3.51% for net sales above $122.9
million. Elan paid aggregate royalties of $24.1 million for 2002. This was
recorded as a cost of sales. In 2001, the royalty rate on net sales of Zanaflex
was 8.44% on the first $38.0 million of net sales and 1.88% for net sales of
Zanaflex above $38.0 million. No royalties were payable on the other products
in 2001. Elan paid aggregate royalties of $5.6 million for 2001.

In December 2001, the Program Agreement was amended such that Elan re-acquired
the royalty rights to Myobloc and disposed of royalty rights on Sonata to
Pharma Marketing. The amendment was transacted at estimated fair value. The
board of directors and shareholders of Pharma Marketing approved this
amendment. The estimated difference in relative fair value between the royalty
rights on Sonata and the royalty rights on Myobloc was $60.0 million. This
amount was paid to Pharma Marketing by Elan in cash and was capitalised by Elan
as an intangible asset.

Under the original agreements, Elan could have, at its option at any time prior
to 30 June 2003, acquired the royalty rights by initiating an auction process.
This date was extended to 3 January 2005 under the settlement with Pharma
Marketing and Pharma Operating described below. In addition, the holders of
Pharma Marketing common shares may initiate the auction process earlier upon
the occurrence of certain events. Pursuant to the auction process, the parties
will negotiate in good faith to agree on a purchase price, subject to Elan's
right to re-acquire the royalty rights at a maximum purchase price. The maximum
purchase price was approximately $413 million at 31 December 2002 and increased
by approximately 25% annually (less royalty payments). The purchase price was
reduced under the settlement with Pharma Marketing and Pharma Operating
described below. If the parties are unable to agree on a purchase price and
Elan elects not to exercise its right to re-acquire the royalty rights at the
maximum purchase price, or if Elan elects not to initiate the auction process
prior to the option termination date, Pharma Marketing can dispose of the
royalty rights in an auction to the highest bidder or retain the royalty
rights. If Elan does not acquire the royalty rights, the royalty rates increase
annually up to a maximum blended effective royalty rate of 52.5% on aggregate
net sales of the products by 2005.

On 17 January 2003, Elan announced that Pharma Operating had filed a lawsuit in
the Supreme Court of the State of New York against Elan and certain of its
subsidiaries in connection with the risk-sharing arrangement between the
parties. The lawsuit sought, among other things, a court determination that
Pharma Operating's approval would be required in the event of a sale by Elan of
its interest in Sonata to a third party. On 30 January 2003, Elan, Pharma
Operating and its parent, Pharma Marketing agreed to settle the lawsuit and,
under the terms of the settlement agreement, Pharma Operating dismissed the
litigation between the parties without prejudice. Pursuant to the settlement
agreement, effective upon the sale of Sonata to King on 12 June 2003, (i) Elan
paid Pharma Operating $196.4 million in cash (representing $225.0 million less
royalty payments on all related products paid or due to Pharma Operating from 1
January 2003 through 12 June 2003) to acquire Pharma Operating's royalty rights
with respect to Sonata and Prialt and (ii) Elan's maximum purchase price for
the remaining products in the arrangement, Zonegran, Frova and Zanaflex, was
reduced to $110.0 million, which will increase at a rate of 15% per annum from
12 June 2003 (less royalty payments made for periods after 12 June 2003). The
parties also agreed to extend Elan's purchase option termination date to 3
January 2005 from the original termination date of 30 June 2003.


- --------------------------------------------------------------------------------

- --------------------------------------------------------------------------------

In connection with the settlement agreement, Elan agreed that it would cause
certain subsidiaries in the United States, Ireland, the United Kingdom,
Germany, France, Spain and Italy to pledge their accounts receivable from
commercial sales of pharmaceutical products and services to Pharma Operating as
collateral to secure Elan's obligations in relation to royalty payments under
the Pharma Marketing arrangement and the settlement agreement. Elan also agreed
that, following the closing of a sale of Sonata, it would grant Pharma
Operating additional collateral to the extent that the aggregate value of the
collateral package, which is to be tested on a quarterly basis, is less than
the maximum purchase price for the royalty rights on Zonegran, Frova and
Zanaflex. On 6 March 2003, EPI and Pharma Operating entered into a security
agreement pursuant to which EPI granted Pharma Operating a first priority
security interest in its accounts receivable from commercial sales of
pharmaceutical products in the United States. On that same date, Elan and
Pharma Operating agreed to the terms of the additional collateral mechanism. On
20 May 2003, EPL and Pharma Operating entered into a security agreement
pursuant to which EPL granted Pharma Operating a security interest in its
accounts receivable from commercial sales of pharmaceutical products and
services in the United Kingdom. A similar agreement was entered into in
relation to Ireland by Elan Pharma Limited (Ireland) on 10 June 2003.
Negotiations have not begun for Germany, France, Spain or Italy. The parties
have agreed that each of the security agreements will provide for the release
of Pharma Operating's lien on any accounts receivable of a product or service
in which Elan disposes of all or a substantial portion of its rights.
Accordingly, Elan does not expect that any of the security arrangements with
Pharma Operating will limit Elan's ability to dispose of assets in connection
with the recovery plan.


Autoimmune

In December 2001, Autoimmune, in an initial tranche, completed a private
placement of its common shares to a group of institutional investors, resulting
in gross proceeds to Autoimmune of $95.0 million. In the same initial tranche,
Elan purchased non-voting preferred shares of Autoimmune's subsidiary for an
aggregate purchase price of $37.5 million. Elan had no representative on the
board of directors of Autoimmune. The existing group of institutional investors
and Elan also committed to a second investment tranche in the same amounts to
be completed in April 2003, subject to certain conditions. Autoimmune entered
into a Program Agreement with Elan. The Program Agreement, which substantially
regulated the relationship between Elan and Autoimmune, represented a
risk-sharing arrangement among the companies. Under the terms of the Program
Agreement, Autoimmune acquired royalty rights to each of the following products
and development projects for the designated indications: (i) Antegren, for the
treatment of relapsing forms of MS, moderate-to-severe inflammatory bowel
disease, including Crohn's disease and ulcerative colitis, and
moderate-to-severe rheumatoid arthritis; (ii) Maxipime, for the treatment of
infection; (iii) Azactam, for the treatment of infection; and (iv) Abelcet, for
the treatment of severe fungal infection. Autoimmune also acquired royalty
rights on certain development projects, as well as any other product
subsequently developed or acquired by Elan that had an indication substantially
the same as Maxipime, Azactam, or Abelcet and that would be in direct
competition with Maxipime, Azactam or Abelcet. Autoimmune agreed to make
payments to Elan in amounts equal to expenditures made by Elan in connection
with the commercialisation and development of these products, subject to
certain limitations. These payments were to be made on a quarterly basis based
on actual costs incurred by Elan. Elan did not receive a margin on these
payments. Elan's revenue from Autoimmune was $68.7 million for 2002, consisting
of $38.8 million for commercialisation expenditures, which has been recorded as
product revenue, and $29.9 million for development expenditures, which has been
recorded as contract revenue. Elan's revenue from Autoimmune was $26.6 million
for 2001, consisting of $15.9 million for commercialisation expenditures, and
$10.7 million for development expenditures. Elan received no revenue from
Autoimmune since June 2002. Elan will not receive any future revenue from
Autoimmune. No royalties were payable to Autoimmune by Elan in either 2002 or
2001.

Under the original agreement, Elan could, at its option at any time prior to
April 2005, acquire the royalty rights by initiating an auction process. In
addition, the holders of the Autoimmune common shares could initiate the
auction process earlier upon the occurrence of certain events. If the auction
process had not been initiated prior to October 2004, it would have
automatically commenced. Pursuant to the auction process, Elan and Autoimmune
would have negotiated in good faith to agree on a purchase price, subject to
Elan's right to re-acquire the royalty rights at a maximum purchase price. This
maximum purchase price increased at various rates, approximately 25% annually,
subject to certain conditions.

In July 2002, Elan announced the termination of all agreements relating to the
risk-sharing arrangement with Autoimmune. The royalty obligations to Autoimmune
were terminated. The total consideration for the royalty rights was $121.0
million which, after taking account of the redemption of Elan's investment of
$38.5 million in Autoimmune, resulted in a net cash cost of $82.5 million. Elan
expensed $121.0 million as an exceptional selling, general and administrative
expense arising from the acquisition of Autoimmune.

At 31 December 2002, Elan had commitments to invest $3.2 million (2001: $25.6
million) in healthcare managed funds.

The Company has deferred purchase arrangements for certain products, which
amount to $4.5 million (2001: $24.5 million). These payments are dependent on
various approvals and milestones being met.

NOTES RELATING TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

Elan, in disposing of assets or businesses, often provides representations,
warranties and indemnities to cover various risks. Elan does not have the
ability to estimate the potential liability from such indemnities because they
relate to unknown conditions. However, Elan has no reason to believe that these
uncertainties would have a material adverse effect on the Group's financial
condition or results of operations.


25 LITIGATION

Elan is involved in various legal and administrative proceedings, relating to
securities matters/SEC investigation, patent matters, antitrust matters and
other matters. The most significant of these matters are described below.

Elan recorded a provision during 2002 of $19.0 million relating to the
litigation with Schwarz, Allergan and the shareholder derivative actions
described below. With the exception of the litigations with Schwarz and
Allergan, and the shareholder derivative actions, Elan does not believe that it
is feasible to predict or determine the outcomes of the pending actions,
investigations and proceedings and any possible effect on the Group's business
or to reasonably estimate the amounts or potential range of losses, if any,
with respect to the pending actions, investigations and proceedings. The costs
and other effects of pending or future litigation, governmental investigations,
legal and administrative cases and proceedings, settlements, judgements and
claims, and changes in those matters (including the matters described below)
and developments or assertions by or against the Group relating to intellectual
property, could have a material adverse effect on the Group's business,
financial condition, results of operations and liquidity.


SECURITIES MATTERS/SEC INVESTIGATION

Commencing in January 1999, several class actions were filed in the U.S.
District Court for the Southern District of California against Dura, one of
Elan's subsidiaries, and various then current or former officers of Dura. The
actions, which allege violations of the U.S. federal securities laws, were
consolidated and purport to seek damages on behalf of a class of shareholders
who purchased Dura common stock during a defined period. In July 2000, the
court issued an order granting the defendants' motion to dismiss the complaint
without prejudice on the basis that it failed to state an actionable claim. In
November 2001, the court granted Dura's motion to dismiss with prejudice and
judgement was entered in Dura's favour. In December 2001, plaintiffs filed an
appeal of the judgement with the Ninth Circuit Court of Appeals. Oral argument
was held on 4 February 2003. On 5 August 2003, the Ninth Circuit issued its
opinion, reversing the lower court's prior dismissal. In remanding the case,
the Ninth Circuit directed that the plaintiffs be afforded leave to amend their
complaint. Elan has petitioned for en banc review of the decision by the entire
panel of the Ninth Circuit. If en banc review is not granted, the Ninth Circuit
will issue a remand to the District Court. The District Court will set a date
for the amended complaint to be filed.

The Company and certain of its former and current officers and directors are
named as defendants in a putative class action in the U.S. District Court for
the Southern District of New York, which consolidated several class actions
filed in early 2002 (the "Class Action"). The amended and consolidated
complaint filed 24 January 2003 in the action (the "Complaint") alleges claims
under the U.S. federal securities laws, specifically, Sections 11, 12(a)(2) and
15 of the Securities Act of 1933, as amended (the "1933 Act"), and Sections
10(b), 14(a) and 20(a) of the Securities Exchange Act of 1934, as amended (the
"1934 Act"), and Rule 10b-5 promulgated thereunder. The Complaint alleges
claims on behalf of classes of persons and entities who purchased securities of
the Company during periods of time commencing on 7 February 2000 and ending on
1 July 2002. The Complaint also alleges claims on behalf of two sub-classes
that consist of persons and entities who held stock in Dura and Liposome and
exchanged such stock for ADSs in Elan pursuant to those companies' mergers with
the Company in 2000. In addition to the Company, defendants named in the
Complaint include Donal J. Geaney, Thomas G. Lynch, Shane M. Cooke, William F.
Daniel, KPMG LLP and KPMG, Chartered Accountants. The Complaint alleges that
the Company's financial statements were not in accordance with generally
accepted accounting principles, and that the defendants disseminated materially
false and misleading information concerning the Company's business and
financial results, with respect to the Company's investments in certain
business ventures and business venture parents and the licence fees and
research revenues received from the business ventures; the accounting for
proceeds from the Company's sale of certain product lines and disclosure
concerning those sales; the accounting for certain risk-sharing arrangements
that the Company entered into and disclosure concerning those arrangements; the
accounting for certain qualified special purpose entities and disclosure
concerning those entities; the disclosure of compensation of certain officers
of the Company; and certain alleged related party transactions. The Complaint
seeks compensatory damages and other relief that the court may deem just and
proper. Elan and the individual defendants moved to dismiss the Complaint on 25
March 2003. The motions to dismiss have been fully briefed; however, the court
has not issued its decision.

The Company is a nominal defendant in two derivative actions filed against
certain of its former and current directors and certain of its former and
current officers on or about 14 March 2002 and 20 March 2002 in the Superior
Court of the State of California, County of San Diego. The two actions have
been consolidated, and the plaintiffs have filed a consolidated complaint. The
complaint contains

- --------------------------------------------------------------------------------
122


- --------------------------------------------------------------------------------

allegations similar to those set forth in the foregoing actions, but alleges,
among other things, that the defendant officers and directors breached their
duties to the Company by causing the Company to undertake the actions alleged
in the complaint. Among other relief, the action seeks damages against the
defendant officers and directors on behalf of the Company. The individual
defendants have filed motions to dismiss on the grounds of lack of personal
jurisdiction, and all of the defendants have filed a motion to dismiss on the
grounds of forum non conveniens, or inconvenient forum. The Company has reached
an agreement with the plaintiffs to settle the derivative actions. The
settlement would involve the Company agreeing to adopt certain corporate
governance provisions and to pay plaintiffs' attorneys' fees and expenses in
the amount of $527,495, as determined by binding mediation. A formal settlement
stipulation has not been finalised. The settlement is subject to court
approval.

The Company is the subject of an investigation by the SEC's Division of
Enforcement commenced on or about 12 February 2002, which the Company believes
relates primarily to the issues described in the immediately preceding two
paragraphs. Elan is unable to predict or determine the outcome of the Class
Action or the SEC investigation or to reasonably estimate the amounts or range
of loss, if any, with respect to the resolution of the Class Action or the SEC
investigation. Elan is also unable to predict or determine the impact, if any,
that the 2001 restatement may have on the outcome of the Class Action. In
addition, the timing and final resolution of the Class Action and SEC
investigation is uncertain. The Company continues to believe that it has
prepared its financial statements in accordance with applicable GAAP (subject
to the restatement relating to EPIL III under U.S. GAAP, described on pages 142
to 147). The findings and outcome of the SEC investigation may adversely affect
the course of the Class Action. The possible outcome or resolution of the SEC
investigation or the Class Action could require Elan to make substantial
payments.


PATENT MATTERS

In September 1999, Bayer A.G. and its U.S. subsidiary Bayer Corporation
(collectively, "Bayer") filed suit in the U.S. District Court for the Northern
District of Georgia claiming that Elan infringes U.S. Patent No. 5,264,446,
allegedly covering Bayer's hypertension drug Adalat CC, by Elan's filing of an
ANDA for its 60mg nifedipine extended release tablets. In March 2001, the court
entered an order granting summary judgement in favour of Elan and dismissed the
action. In May 2000, Bayer filed another lawsuit against Elan, along with
Biovail Corporation ("Biovail") and Teva Pharmaceuticals, USA, Inc. ("Teva"),
alleging that the commercial sale of Elan's 30mg nifedipine extended release
tablets infringes the same Bayer patent (originally filed in the U.S. District
Court for the District of Delaware and transferred to the U.S. District for the
Northern District of Georgia). In March 2001, the court entered an order
granting summary judgement in favour of Elan and dismissed the action. Bayer
appealed both decisions to the U.S. Court of Appeals for the Federal Circuit
("CAFC"). In February 2002, the CAFC issued a decision vacating the district
court's decision in both cases and remanding for further proceedings. In August
2002, the Company entered into a settlement with Bayer resolving all
outstanding disputes over Elan's 30mg and 60mg nifedipine products, and
providing Elan with freedom to commercially manufacture and sell those products
without liability to Bayer. The cases were dismissed with prejudice in August
2002.

In March 2001, Novartis Consumer Health, Inc. ("Novartis") filed a complaint
against Elan Transdermal Technologies, Inc. ("ETT"), a wholly owned subsidiary
of Elan, in the U.S. District Court for the Southern District of Florida
alleging that ETT's nicotine patch products infringe Novartis' U.S. Patent No.
5,834,011 (the "011 patent"). Novartis' complaint sought unspecified damages
and an injunction barring the sale of ETT's nicotine patch products. In May
2001, ETT answered the complaint, denying infringement and alleging the
invalidity and unenforceability of the 011 patent. ETT, along with Elan
Transdermal Limited ("ETL"), also asserted a counterclaim against Novartis,
alleging that Novartis' nicotine patches infringe the Group's U.S. patent No.
4,946,853 (the "853 patent"), and seeking damages and injunctive relief. In
June 2001, Novartis answered the counterclaims, denying infringement, asserting
the invalidity of the 853 patent, and stating that the patent was unenforceable
against Novartis on account of equitable estoppel and that any recovery of
damages would be limited by laches. In November 2002, ETT, ETL and Novartis
entered into a stipulation and Order of Dismissal, whereby both the claim and
the counterclaim were dismissed. This ended the litigation and resolved the
claims on terms which allow ETT to continue to market its nicotine patch
products for prescription use. On 8 July 2003, Nitto Americas acquired all of
the outstanding capital stock of ETT.

In October 1998, Elan filed a patent infringement action in the U.S. District
Court for the Southern District of Florida against Andrx alleging that, by its
submission of an ANDA for a generic version of Naprelan, which submission
included a paragraph IV certification, Andrx infringed Elan's U.S. Patent No.
5,637,320 (the "320 patent"). In March 2002, the court issued a decision
finding the 320 patent invalid and dismissed the action. The court did not
consider the issue of infringement. In March 2003, the court denied Elan's
motion for reconsideration and confirmed its previous finding of invalidity.
Elan has filed a notice of appeal with the CAFC and Elan submitted its opening
brief on July 30, 2003. A response brief by Andrx is scheduled to be submitted
in September 2003.



In November 2002, Allergan filed a complaint against Elan in the U.S. District
Court for the District of Delaware. The complaint alleges that Elan wilfully
infringed U.S. Patent No. 6,290,961 by virtue of its manufacture, sale and
offer for sale of its Myobloc product. Allergan

is seeking injunctive relief and unspecified damages. In February 2003 Elan
filed an answer and counterclaim, denying allegations of infringement,
asserting that the patent is invalid and unenforceable and alleging antitrust
violations against Allergan. In February 2003, Allergan filed its reply to
Elan's counterclaim. A trial date has been set for October 2004. Settlement
discussions are on-going.

Eon submitted to the FDA an ANDA for a generic equivalent of Elan's 400mg
Skelaxin product. The application included a paragraph IV certification
pertaining to U.S. patent No. 6,407,128 (the "128 patent"). Eon provided notice
to Elan of its paragraph IV certification in November 2002, and Elan filed a
patent infringement suit against Eon in the U.S. District Court for the Eastern
District of New York on 2 January 2003. Eon filed its answer and counterclaim
on 23 January 2003 and then filed an amended answer and counterclaim on 19
February 2003. Elan filed its reply to the counterclaim on 7 March 2003.
Discovery is in its early stages and no trial date has been set. Corepharma LLC
("Corepharma") also has submitted to the FDA an ANDA for a generic equivalent
of Elan's 400mg Skelaxin product, including a paragraph IV certification
pertaining to the 128 patent. Corepharma provided notice to Elan of its
paragraph IV certification in January 2003, and Elan filed a patent
infringement suit against Corepharma in the U.S. District Court for the
District of New Jersey on 7 March 2003. In May 2003, Elan and Corepharma agreed
to transfer the Corepharma litigation to the U.S. District Court for the
Eastern District of New York for consolidation with the Eon litigation. Elan
and King are cooperating in the prosecution of these actions, and are working
together to substitute, or in the alternative add, King as a plaintiff to the
two actions.


ANTITRUST MATTERS

In March 2001, Andrx filed a complaint against Elan in the U.S. District Court
for the Southern District of Florida alleging that Elan engaged in
anti-competitive activities in an effort to prevent or delay the entry of a
generic alternative to Naprelan. Elan filed a motion to dismiss the complaint
and for judgement on the pleadings. In April 2003, the court granted Elan's
motion and dismissed Andrx's complaint with prejudice and without leave to
amend. In June 2003, the court reaffirmed its April decision, denying Andrx's
motions for reconsideration and for leave to amend its complaint. On 14 July
2003, Andrx filed a notice of appeal. The opening brief in this matter is
likely to be filed in October 2003. In addition, the 11th Circuit has
tentatively scheduled a September 23, 2003 mediation regarding this matter.

Three putative class actions have been filed in the U.S. District Court for the
Eastern District of Pennsylvania against Elan and Skye Pharma, Inc. by indirect
purchasers of Naprelan. In September 2002, the cases were consolidated and in
October 2002, a consolidated amended class action complaint was filed. The
consolidated complaint alleges that Elan violated the antitrust laws by
engaging in sham patent litigation and entering into an unlawful settlement
agreement in an effort to prevent or delay the entry of a generic alternative
to Naprelan. The damages claimed are unspecified. Elan has not yet answered or
otherwise responded to the amended complaint. Other than preliminary document
production, the litigation has been stayed and the case placed on the court's
suspense docket pending the outcome of further proceedings in the pending
patent infringement litigation brought by Elan against Andrx described above.
On August 4, 2003 plaintiffs filed a motion to remove the litigation from the
court's suspension docket. Elan and Skye Pharma, Inc. have filed an opposition
to this motion and currently await the court's decision on this matter.

In June 2001, Elan received a letter from the FTC stating that the FTC was
conducting a non-public investigation to determine "whether Brightstone Pharma,
Inc., Elan Corporation or others may have engaged in an effort to restrain
trade by entering into an agreement which may restrict the ability of
Brightstone or others to market a bioequivalent or generic version of
Naprelan". In October 2001, counsel for Elan met informally with FTC Staff to
discuss the matter. No further communication from the FTC was received until
December 2002, when Elan was served with a subpoena duces tecum from the FTC
for the production of documents related to Naprelan. Elan has voluntarily
provided documents and witness testimony in response to the subpoena and
continues to cooperate with the FTC relating to this investigation.

In June 2002, Elan entered into a settlement with the FTC resolving the FTC's
investigation of a licensing arrangement between Elan and Biovail relating to
nifedipine, the generic version of the hypertension drug Adalat CC. The
settlement is reflected in a consent order which, by its terms, does not
constitute an admission by Elan that any law has been violated, and does not
provide for monetary fines or penalties. Elan continues to satisfy all of the
terms of the consent order, including launching its 30mg and 60mg nifedipine
products through Watson in September 2002.

Elan is aware that ten actions have been filed in the U.S. District Courts on
various dates between July 2002 and July 2003 (seven in the District of
Columbia and three in the Southern District of New York) claiming that Elan
(and others) have violated federal and state antitrust laws based on the
licensing arrangement with Biovail relating to nifedipine described in the
immediately preceding paragraph. The complaints seek various forms of remedy,
including declaratory judgement, damages (including treble and/or punitive
damages where allowed), disgorgement and injunctive relief. The actions have
been brought by putative classes of direct purchasers, individual


- --------------------------------------------------------------------------------
124


- --------------------------------------------------------------------------------

direct purchasers, and putative classes of indirect purchasers. On 29 May 2003,
the Multidistrict Panel granted Elan's and Biovail's motion to coordinate and
consolidated for pre-trial proceedings all pending cases in the District of
Columbia. The court has not set a case management schedule.

On 13 March 2003, Elan received notification from the FTC that the FTC's Bureau
of Competition was conducting an investigation to determine whether Elan, King
or any other person was engaging in unfair methods of competition in violation
of Section 5 of the Federal Trade Commission Act, including, among other
things, by preventing or slowing generic competition to Skelaxin. The FTC's
stated focus of the investigation was Elan's listing in the Orange Book of at
least one patent for Skelaxin, and other actions with regard to the FDA
regulatory process. On 8 May 2003, Elan received notification from the FTC that
it had discontinued that portion of its investigation concerning whether Elan
wrongfully listed its patent for Skelaxin in the Orange Book. Elan continues to
cooperate with the FTC regarding matters unrelated to the Orange Book listing
of the Skelaxin patent.


OTHER MATTERS

On 27 June 2002, BioPort Corporation ("BioPort") filed suit against Elan in the
Superior Court of the State of California alleging breach of certain
collaboration and supply agreements relating to the development, manufacture
and supply of botulinum toxin. In addition to claims for breach of contract,
BioPort asserted claims for intentional interference with contractual relations
(as to Elan), unfair business practices, and unjust enrichment. The complaint
sought a five percent royalty on net sales of Myobloc, payments allegedly owned
under the collaboration agreement, a declaration that BioPort has an ownership
interest in Myobloc, and other relief including punitive damages. On 17 March
2003, the court sustained Elan's demurrer to BioPort's claim for unfair
business practices. On 1 April 2003, Elan filed an answer to BioPort's
complaint, including a general denial of the complaint and affirmative
defences. Elan also filed a cross-complaint against BioPort, seeking
declaratory relief and damages for breach of contract. On 19 May 2003, BioPort
filed a demurrer to Elan's cross-complaint. On 20 May 2003, Elan filed a motion
to strike BioPort's demurrer. On 30 May 2003, BioPort and Elan both filed
motions for summary adjudication. On 5 June 2003, the parties participated in
mediation. After the mediation, the court stayed the litigation until 24 August
2003 to allow the parties to continue business negotiations that may resolve
the dispute. The parties are scheduled to appear before the court on 18
September 2003 for a status review.

In September 2002, Schwarz filed a demand for arbitration with the American
Arbitration Association (the "AAA") claiming that Elan had breached certain
duties associated with a License and Supply Agreement between Elan and Schwarz
for the distribution of Verelan SR and Verelan PM and seeking unspecified
damages. In October 2002, the Company filed an Answer and Counterclaim to the
Demand. On 28 April 2003, the parties entered into an amendment to their
License and Supply Agreement and settled all the claims raised in the demand
for arbitration.

On 17 January 2003, Elan announced that Pharma Operating had filed a lawsuit in
the Supreme Court of the State of New York against Elan and certain of its
subsidiaries in connection with the risk-sharing arrangement between the
parties. The lawsuit sought, among other things, a court determination that
Pharma Operating's approval would be required in the event of a sale by Elan of
its interest in Sonata to a third party. On 30 January 2003, Elan, Pharma
Operating and its parent, Pharma Marketing, agreed to settle the lawsuit and,
under the terms of the settlement agreement, Pharma Operating dismissed the
litigation between the parties without prejudice. Pursuant to the settlement
agreement, effective upon the sale of Sonata to King on 12 June 2003, (i) Elan
paid Pharma Operating $196.4 million in cash (representing $225.0 million less
royalty payments on all related products paid or due to Pharma Operating from 1
January 2003 through 12 June 2003) to acquire Pharma Operating's royalty rights
with respect to Sonata and Prialt and (ii) Elan's maximum purchase price for
the remaining products in the arrangement, Zonegran, Frova and Zanaflex, was
reduced to $110.0 million, which will increase at a rate of 15% per annum from
12 June 2003 (less royalty payments made for periods after 12 June 2003). The
parties also agreed to extend Elan's purchase option termination date to 3
January 2005 from the original termination date of 30 June 2003.

In connection with the settlement agreement, Elan agreed that it would cause
certain subsidiaries in the United States, Ireland, the United Kingdom,
Germany, France, Spain and Italy to pledge their accounts receivable from
commercial sales of pharmaceutical products and services to Pharma Operating as
collateral to secure Elan's obligations in relation to royalty payments under
the Pharma Marketing arrangement and the settlement agreement. Elan also agreed
that, following the closing of a sale of Sonata, it would grant Pharma
Operating additional collateral to the extent that the aggregate value of the
collateral package, which is to be tested on a quarterly basis, is less than
the maximum purchase price for the royalty rights on Zonegran, Frova and
Zanaflex. On 6 March 2003, EPI and Pharma Operating entered into a security
agreement pursuant to which EPI granted Pharma Operating a first priority
security interest in its accounts receivable from commercial sales of
pharmaceutical products in the United States. On that same date, Elan and
Pharma Operating agreed to the terms of the additional collateral mechanism. On
20 May 2003, EPI and Pharma Operating entered into a security agreement
pursuant to which EPL granted Pharma Operating a security interest in its
accounts receivable from commercial sales

of pharmaceutical products and services in the United Kingdom. A similar
agreement was entered into in relation to Ireland by Elan Pharma Limited
(Ireland) on 10 June 2003. Negotiations have not begun for Germany, France,
Spain or Italy. The parties have agreed that each of the security agreements
will provide for the release of Pharma Operating's lien on any accounts
receivable of a product or service in which Elan disposes of all or a
substantial portion of its rights. Accordingly, Elan does not expect that any
of the security arrangements with Pharma Operating will limit Elan's ability to
dispose of assets in connection with the recovery plan.

On 17 March 2003, the Group commenced an action against King and certain of its
subsidiaries in the Supreme Court of the State of New York to compel King to
complete its purchase of the Group's primary care franchise (principally
consisting of the Group's U.S. and Puerto Rican rights to Sonata and Skelaxin).
On 19 May 2003, Elan and King agreed to proceed with the transaction on amended
terms and on 12 June 2003 the transaction was completed. Effective upon the
closing of the transaction, all claims under the pending litigation were
released and Elan and King dismissed the litigation with prejudice.


26 BUSINESS VENTURES

Since 1996, Elan has pursued collaborations with biotechnology, drug delivery
and pharmaceutical companies in order to leverage Elan's drug delivery
technologies and its proprietary neurological and oncology research, and to
access complementary or synergistic research and development programmes in
Elan's areas of expertise. Elan has historically referred to this programme in
a number of ways, including as a joint venture programme, a business venture
programme, and a strategic licensing programme. For the purposes of these
Consolidated Financial Statements, this programme will be referred to as the
"business venture programme". Elan has not entered into any new business
ventures under the business venture programme since mid-2001.

In 2002, as part of the recovery plan, Elan completed a review of its business
venture portfolio to conserve cash and reflect the reduced scope of Elan's
activities. As a result, it is Elan's intention to restructure or terminate
substantially all of its business ventures with the aim of substantially
reducing or eliminating future cash outlays by Elan. The restructuring process
and any terms agreed have been the result of negotiations between Elan and the
respective business venture parents. As such, the agreed terms arising from the
restructuring process vary between different business venture relationships.
Typically, as part of the termination of a business venture, the technologies
contributed by the business venture parent and Elan are returned, the
technology developed in the business venture is transferred to the business
venture parent and/or Elan, and Elan transfers its interest in the business
venture to the business venture parent in exchange for a continuing interest in
the product or technology previously in the business venture, such as a
royalty. There can be no assurance that all business venture relationships can
be restructured or terminated on commercially reasonable terms, or at all.
There were 55 business ventures in place prior to the announcement of the
recovery plan on 31 July 2002. To date, Elan has formally restructured 36
business venture relationships.

As it is Elan's intention to restructure or terminate substantially all of its
business venture relationships, the description of the business venture
programme below is generally no longer applicable and is described in the past
tense.

The business venture programme generally involved licensing drug delivery
technologies and know-how, or pharmaceutical research and development assets,
to a newly formed subsidiary ("the business venture") of an emerging
biotechnology; drug delivery or pharmaceutical company ("the business venture
parent") and the establishment of a joint development collaboration.

Contemporaneously with the licensing and collaborative transaction, Elan
typically made an investment in the business venture. Investments in business
ventures were in various forms. Prior to mid 1999, those investments were
generally in the form of voting common stock. Subsequently, these investments
were in the form of non-voting preferred stock convertible into common stock
after a period of two years. Elan typically held an initial fully diluted
equity interest of 19.9% in the business venture. Elan also typically made a
contemporaneous investment in the business venture parent in the form of common
equity and convertible/exchangeable preferred stock and/or
convertible/exchangeable debt. The convertible/exchangeable securities in the
business venture parent were generally convertible, at Elan's option, into
common equity of the business venture parent or exchangeable for up to 30.1% of
the common equity in the business venture, potentially bringing Elan's fully
diluted equity interest in the business venture up to 50%. In many
transactions, if Elan chose to exchange the convertible/exchangeable securities
in the business venture parent into common equity of the business venture, then
it would be required to pay the business venture parent an amount equal to
30.1% of the cumulative operating funding of the business venture to the date
of exchange such that Elan and the business venture parent would have shared
equally (on a cumulative basis) in such funding. Elan sold certain of its
investments in the business ventures and the business venture parents to EPIL
II in June 2000 and to EPIL III in March 2001. EPIL II and EPIL III are
securitisation entities and the investments are held by EPIL II and EPIL III as
security for outstanding indebtedness issued by the entities. For additional
information regarding these special purpose entities, please refer to Notes 16
and 33 to the Consolidated Financial Statements.


- --------------------------------------------------------------------------------

- --------------------------------------------------------------------------------

The business venture generally conducted research and development activities
using its technologies and proprietary know-how in an agreed research field.
Elan's partner, the business venture parent, principally managed the business
venture. The technologies and proprietary know-how of the business venture were
in-licensed by the business venture from Elan and the business venture parent.
On formation, a number of contracts were entered into to govern the
in-licensing of intellectual property assets to the business venture from Elan
and the business venture parent.

Development of products and technologies for pharmaceutical applications
involves risk. The nature of pharmaceutical development, with stringent
regulatory constraints and guidelines designed to protect the health and safety
of patients and those working with the products, means that development
activities are costly and time consuming. Elan's portfolio of business ventures
allowed it to diversify the risks associated with product development.
Individual development programmes within the business ventures had varying
degrees of success and failure. Elan and the business venture parent would
typically work together using commercially reasonable efforts and their
combined technical, regulatory and clinical expertise to increase the
likelihood of success of the business ventures. This could lead to changes in
the direction of a development programme, adding or substituting technologies
or products and redirection of clinical programmes as deemed necessary.

The business venture, the business venture parent and Elan continually reviewed
the progress of the research and development activities in the business
venture. As part of this review, the parties could decide that it was not
commercially or technically practical to continue to support the business
venture.

Elan received and recorded initial revenue from the business ventures set out
in the tables on pages 128 to 130 of $Nil, $172.5 million and $321.2 million
for 2002, 2001 and 2000, respectively. Elan's initial investments in the
business ventures and the business venture parents were $Nil, $229.2 million
and $435.7 million for 2002, 2001 and 2000, respectively.

The business ventures typically had the following operational structure. The
board of directors of a business venture was generally comprised of a majority
of directors from the business venture parent and one director nominated by
Elan. For a quorum, the presence of the Elan nominated director was required.
The business plan required the approval of the board of directors of the
business venture, including the Elan nominated director. This approval was
subject to the directors' fiduciary duty to the business venture. The contracts
of establishment provided for subsequent reviews, either annually or more
frequently, of the business plan and required the continuing approval by the
Elan nominated director. The business ventures also typically had a management
committee and/or research and development committee. These committees generally
provided for equal representation by Elan and the business venture parent. The
committees had responsibility for day to day activities of the business venture
and for the implementation of the business plan. At their inception, the
business ventures typically had no funds after payment of the initial fee to
Elan. The operating funding of the business venture was provided by the
business venture parent and Elan, subject to the approval of both parties.
Funding was generally utilised to pay for research and development activities.
Typically, such subsequent financial support was provided in proportion to the
respective fully diluted ownership of the business venture by the business
venture parent and Elan (typically 80.1% and 19.9%, respectively). Elan
expensed the subsequent funding it provided directly to the business venture.
This was expensed within the interest and other expense line. Elan expensed
$23.9 million, $24.6 million and $10.0 million of subsequent business venture
funding in 2002, 2001 and 2000, respectively. If both Elan and the business
venture parent agreed to provide subsequent financial support to the business
venture through their ongoing approval of a business plan, then, if requested
by the business venture parent, Elan was required to make additional
investments in the business venture parent, typically in the form of
convertible debt, in an amount equal to the business venture parent's
proportion of such subsequent financial support, the proceeds of which the
business venture parent was required to use to fund its proportion of the
subsequent support of the business venture. This amount was recorded by Elan as
a financial asset. Elan provided additional financing of $83.4 million, $92.2
million and $41.3 million to business venture parents in 2002, 2001 and 2000,
respectively. As a consequence of the implementation of the recovery plan, Elan
expects that the amount of additional financing it will provide to the business
ventures and business venture parents in 2003 will be less than $10.0 million.

The business ventures incurred research and development expenditures of
approximately $125 million, $125 million and $70 million in 2002, 2001 and 2000
respectively. While the business ventures and the business venture parents were
generally responsible for ongoing research and development activities, they
could request that Elan conduct research and development on their behalf. If
Elan undertook such work, the work was typically charged to the business
venture at pre-determined rates, which were set to recover Elan's costs plus a
mark-up. Elan received research revenue from the business ventures of $13.4
million, $15.0 million and $15.4 million in 2002, 2001 and 2000, respectively.

Investments in the business ventures and the business venture parents were made
at fair value. The fair value of investments was typically initially determined
by Elan using established financial methodologies, including quoted market
prices for quoted equity securities. Unquoted equity investments and non-traded
securities of public entities were assessed using methodologies including the
Black-Scholes

- --------------------------------------------------------------------------------

- --------------------------------------------------------------------------------

option-pricing model, the valuation achieved in the most recent private
placement by an investee, an assessment of the impact of general private equity
market conditions, and discounted projected future cash flow models.

Subsequent to Elan's investment in a business venture and business venture
parent, the values of the investments have been typically determined
periodically, but not less frequently than yearly, by an independent financial
institution using methodologies similar to those described above.

The tables on pages 128 to 130 set forth certain information regarding the 36
business ventures that were formed in 2001 and 2000. No new business ventures
were formed in 2002. Of all of the business ventures formed since the
commencement of the business venture programme in 1996, 55 were still in place
prior to the announcement of the recovery plan on 31 July 2002. It is Elan's
intention to restructure or terminate substantially all of its business
ventures. To date Elan has formally restructured 36 business venture
relationships.

Elan recognised exceptional charges in its profit and loss account for 2002 to
reflect impairments to the Group's investment portfolio, including investments
held by EPIL II and EPIL III. This includes impairment charges relating to
investments in business ventures and business venture parent companies of
$114.4 million and $880.0 million respectively.

27 RELATED PARTIES


ANTIGENICS

At 31 December 2002, the Company had invested a total of $14.9 million (2001:
$12.9 million) in Antigenics Inc., a biotechnology company whose chairman, Dr
Garo Armen, is also the chairman of Elan. Elan's investments in Antigenics,
consisting of common stock holdings, were made in 1998 ($2.5 million), 1999
($10.4 million) and January 2002 ($2.0 million). At 31 December 2002, Elan's
shareholding represented approximately 3.3% of Antigenics' outstanding share
capital. At 31 December 2002, this investment had a carrying value of $11.0
million.

Following the appointment of Dr Armen as chairman on 9 July 2002, the Company
signed a memorandum of understanding between itself and Antigenics in respect
of costs incurred by either company in respect of work done for the other. The
agreement provided that no profit margin should be charged on such costs. In
2002, the amount of such charges from Antigenics to the Company was $44,888.

DR SELKOE

Dr Selkoe, a director of Elan, received $50,000 and $62,500 from Elan in 2002
and 2001, respectively, under consultancy agreements with the Group.


MR GROOM

Mr Groom, a director of Elan, received $200,000 in 2002 under a consultancy
agreement with the Group.


AMARIN

Amarin is a specialty pharmaceutical company focused on neurology and pain
management. Mr Thomas Lynch, an employee of Elan and formerly its executive
vice chairman, and Mr John Groom, a director of Elan, serve on Amarin's board
of directors. Mr Lynch is non-executive chairman of Amarin. Mr Michael Coffee
and Mr Donald Joseph, both employees of Amarin, were previously employed by
Elan.

In May 2001, Elan and Amarin entered into a distribution and option agreement,
whereby Amarin agreed to market and distribute Permax in the United States, and
was granted an option to acquire rights to the product from Elan. Permax is
used for the treatment of Parkinson's disease and falls within Amarin's focus
on neurology. In September 2001, this agreement was amended, whereby Amarin was
appointed the sole distributor of Permax in the United States until August
2002. Elan recorded consideration of $45.0 million under the terms of the
amended distribution and option agreement and retained a royalty right of 3.5%
on net sales of Permax by Amarin from 1 January 2002 through the date on which
Amarin exercised or terminated its option to acquire Permax. In 2001, Elan also
recorded a net amount of $6.2 million from Amarin for distribution fees and
royalties on sales of Permax. After reducing the carrying value of the Permax
intangible and equity accounting, Elan recorded net revenue from Amarin of
$16.9 million in 2001 which includes the distribution revenue. Amarin's option
to purchase Permax was exercisable between September 2001 and May 2002 for an
exercise price of $37.5 million, payable $7.5 million on exercise of the option
and $2.5 million in quarterly instalments thereafter, and a royalty of between
7% and 10% on future net sales of Permax by Amarin. The royalty would have been
reduced or increased by up to $8.0 million if Permax revenues in 2003 and 2004
are less than (for a royalty reduction) or greater than (for a royalty
increase) $26.0 million and $16.0 million, respectively. On 11 March 2002,
Amarin exercised its option to acquire Permax and paid Elan the first
instalment of the exercise price of $7.5 million. Elan has not recognised the
unpaid option exercise price, but rather intends to record such consideration
as it is received due to uncertainties surrounding its ultimate collectibility.
In January 2003, in addition to the amendments described below, Elan and Amarin
agreed to amend certain terms of their agreements including a reduction of $7.5
million in the total quarterly deferred option payments due to Elan in 2004 and
2005, incurred in connection with the acquisition of the Permax rights by
Amarin, and the inclusion of Elan's shares in the registration statement filed
for the investors in connection with the private placement described below.
Elan has agreed not to sell any of those shares until 1 October 2003, with
certain exceptions. Further as described below, Elan and Amarin further amended
their agreements in August 2003, such that Amarin may discharge in full its
obligations to Elan under the loans referred to above and its remaining
obligations to Elan arising from its exercise of the Permax option for a
payment of $30.0 million.

In connection with the amended distribution and option agreement, Elan provided
a loan of $45.0 million to Amarin. The loan bears interest at a rate equal to
LIBOR plus a margin of 2%. The loan originally matured on 28 September 2002. In
July 2002, the maturity date of the loan was amended to $2.5 million payable in
July 2002 (repaid in July 2002), $17.5 million payable in September 2002, $10.0
million payable in September 2003 and $15.0 million payable in September 2004.
In January 2003, $19.9 million of this loan, including interest of $2.4
million, was repaid by Amarin and the maturity of the remaining amount of the
loan was amended to $10.0 million payable in September 2004 and $15.0 million
payable in September 2005. Further amendments to the agreements with Amarin
were entered into during August 2003 and are described below.

During 2001, Elan granted Amarin a purchase option to acquire Zelapar. Zelapar
is a fast melt formulation of selegiline for the treatment of Parkinson's
disease. The purchase option was amended in January 2003, and was exercisable
until 30 days after FDA approval of Zelapar. If Amarin exercised the option
Elan would have received approximately $10 million, and may have additionally
received revenue-contingent milestone payments of up to $32.5 million. Elan
would have also received a royalty of 12.5% on future net sales of Zelapar by
Amarin. Further amendments to the agreements with Amarin were entered into
during August 2003 and are described below.


In August 2003, Elan and Amarin agreed to further amend certain terms of their
agreements whereby Amarin has until 31 December 2003 to pay $30.0m to Elan. If
Amarin does so, all loans referred to above and outstanding deferred payments
due in connection with

NOTES RELATING TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

the purchase of Permax will be discharged in full, and Amarin will be deemed to
have exercised its option to acquire Zelapar. Elan will additionally receive a
royalty of 12.5% of net sales of Zelapar by Amarin, and may receive a future
revenue-contingent milestone payment of $10.0 million in ordinary shares of
Amarin if annual sales of Zelapar exceed $20.0 million. Further, in the event
that Amarin raises in excess of $40.0 million from financings or specified
asset sales by 30 June 2004, Amarin will be obliged to apply half the excess,
up to a maximum of $10.0 million, to reduce the rate of the royalty on net
sales. The royalty rate will be reduced by 0.5% of net sales for each $1.0
million paid to Elan. If Amarin does not pay Elan $30.0 million by 31 December
2003, then all such debts and deferred payments will become due and payable on
demand by Elan and the Zelapar option will be deemed cancelled and
nonexercisable. In that event, Elan will additionally be entitled at its option
to convert all amounts owed to the Group by Amarin into ordinary shares of
Amarin at any time. The amounts owed will be converted into Amarin ordinary
shares at a price equivalent to the average closing price per Amarin share for
the five days prior to the date that the option to convert is exercised. Amarin
granted to Elan fixed and floating security over its assets and business to
secure payments due to Elan. This security will be reduced to $5.0 million in
the event that Amarin pays the $30.0 million amount referred to above by 31
December 2003. The royalty increase or decrease for Permax based on sales in
2003 and 2004 was eliminated. Amarin is entitled to redeem the Permax royalty
at any time by paying $700,000 to Elan. All quarterly payments due in
connection with the purchase of Permax and all loan interest payments due are
subject to a moratorium that expires on 31 December 2003.

At 31 December 2002, Elan held approximately 27% of the outstanding ordinary
shares of Amarin and also held preferred shares convertible into,
approximately, an additional 12% of Amarin's equity on a fully diluted basis.
On 28 January 2003, Amarin announced the completion of a private placement for
gross proceeds of $21.2 million. In connection with this transaction Elan also
converted 2,000,000 Amarin convertible preference shares into ordinary shares.
As a result of these transactions, Elan's share ownership in Amarin is
approximately 26% on a fully diluted basis.

Under Irish GAAP Elan accounted for Amarin using the equity method, based on
Elan's fully diluted equity investment in Amarin in 2001 and 2002. Amarin is a
related party to Elan. Elan recorded net revenue from Amarin of $4.8 million in
2002 (2001: $16.9 million). Elan's total investment in Amarin at 31 December
2002 amounted to $63.2 million, consisting of loans, including interest, of
$44.8 million and $6.5 million and a net equity investment of $11.9 million. As
described above, Amarin repaid $17.5 million of this loan and interest of $2.4
million in January 2003. In addition, Elan has trading balances due from Amarin
of $13.7 million at 31 December, 2002 (2001:$Nil).

Amarin's financial position at 31 December 2002 was as follows: current assets
Sterling29.6 million (2001: Sterling28.6 million), non-current assets
Sterling31.0 million (2001: Sterling33.9 million), current liabilities
Sterling41.6 million (2001: Sterling36.9 million) and non-current liabilities
Sterling22.8 million (2001: Sterling5.2 million).


Amarin's results of operations for the year ended 31 December 2002 were as
follows: turnover Sterling40.6 million (2001: Sterling39.2 million), gross
profit Sterling22.0 million (2001: Sterling23.4 million), operating loss from
continuing operations Sterling20.3 million (2001: Sterling3.5 million) and loss
for the financial year Sterling23.0 million (2001: Sterling3.3 million).


28 PENSION PLANS

The Company has continued to account for pensions in accordance with SSAP No.
24, "Accounting for Pensions" ("SSAP 24"), and the disclosures given in (a) are
those required by that standard. FRS 17 "Retirement Benefits" ("FRS 17") will
not be mandatory for the Company until the year ended 31 December 2005. Prior
to this, phased transitional disclosures are required by FRS 17 and, to the
extent they are not given in (a), are set out below in (b).

- -------------------------------------------------------------------------------


(I) DEFINED BENEFIT SCHEMES

The Company funds the pension entitlements of certain employees through defined
benefit plans. Two plans are operated for Irish employees. In general, on
retirement, a member is entitled to a pension calculated at 1/60th of final
pensionable salary for each year of

- --------------------------------------------------------------------------------
132


- --------------------------------------------------------------------------------

pensionable service, subject to a maximum of 40 years. These plans are funded
externally and the related pension costs and liabilities are assessed in
accordance with the advice of a professionally qualified actuary. The
investments of the plans at 31 December 2002 consisted of units held in
independently administered funds. The most recent actuarial valuations of the
plans were carried out in April 2002 using the projected unit credit method and
the valuation reports are not available for public inspection.

The principal actuarial assumption used was that the rate of real investment
returns will exceed the rate of salary inflation by 2%.

The actuarial report showed that at 1 April 2002, the market value of the
assets of the schemes was $19.4 million and the actuarial value of the assets
represented 106% of the benefits accrued to members for the two plans.

These schemes are fully funded on a discontinuance basis.


(ii) Defined contribution schemes

In addition, Elan operates a number of defined contribution pension plans,
primarily for employees outside of Ireland. The costs of these plans are
charged to the profit and loss account in the period in which incurred.


(iii) Balance sheet amounts

At the year ended 31 December 2002, there was a pension contribution due
included in accruals of $0.5 million (2001: $5.1 million) and a pension
prepayment of $0.2 million (2001: $0.2 million).


(B) FRS 17 RETIREMENT BENEFITS

The valuations of the defined benefit schemes used for the purpose of FRS 17
disclosures have been based on the most recent actuarial valuations as
identified above. These have been updated by the actuary to take account of the
requirements of FRS 17 in order to assess the liabilities at each balance sheet
date. Scheme assets are stated at their market value at each balance sheet
date. The contribution rate, inclusive of the members contributions, for the
Employee Benefit Plan is 17.4% of pensionable salaries. The contribution rate,
inclusive of the members contributions, for the Pension and Life Assurance Plan
is 30.1% of pensionable salaries.

The financial assumptions used to calculate the retirement benefit liability
under FRS 17 were as follows:

29 POST BALANCE SHEET EVENTS


Mr Martin

On 7 January 2003, Elan and EPI entered into an agreement with Mr Martin such
that Mr Martin was appointed president and chief executive officer of Elan
effective 3 February 2003. Mr Martin's annual salary under this agreement is
$798,000. He is eligible for an annual bonus in a target amount equal to his
salary depending on the achievement of established performance goals. Mr Martin
was granted an initial option to purchase 1,000,000 Ordinary Shares with an
exercise price of $3.85 and vesting in three equal instalments on 31 December
2003, 31 December 2004, and 31 December 2005. It is anticipated that Elan will
grant an additional option to Mr Martin to purchase 1,000,000 Ordinary Shares
with an exercise price equal to the fair market value of the shares on the date
of grant, vesting on the same basis and dates as the initial option grant,
following Elan's 2003 Annual General Meeting.

Commencing in 2004, Mr Martin will be considered for additional option grants
during the term of the agreement consistent with Elan's annual option grant
practices.

The agreement continues until 31 December 2005 and can be extended for a
further year on each anniversary of that date thereafter unless 90 days notice
is given by Elan or Mr Martin prior to the applicable anniversary date. In
general, if Mr Martin's employment is involuntarily terminated (other than for
cause or disability) or Mr Martin leaves for good reason, Elan will continue to
pay his salary and target bonus for the following two years and his outstanding
options will immediately accelerate and remain outstanding for the following
two years. If, during the first two years of the agreement, Elan undergoes a
change in control and Mr Martin is involuntarily terminated, then Mr Martin
will receive the benefits outlined in the preceding sentence together with a
cash payment equal to the hypothetical value of the options to purchase
1,000,000 Ordinary Shares anticipated to be granted following Elan's 2003
Annual General Meeting, to the extent not then granted, and a lump sum payment
in an amount equal to $5.0 million if the change of control occurs in the first
year of the term or $3.0 million if it occurs in the second year of the term.

Mr Martin will be eligible to participate in the pension, medical, disability
and life insurance plans applicable to senior executives in accordance with the
terms of those plans. He may also receive financial planning and tax support
and advice from the provider of his choice at a reasonable and customary annual
cost.


King

On 30 January 2003, Elan announced that it had agreed to sell its primary care
franchise, principally consisting of its U.S. and Puerto Rican rights to Sonata
and Skelaxin, related inventory and related rights to enhanced formulations of
these products, to King. On 17 March 2003, Elan commenced a lawsuit against
King to compel King to complete its purchase of the primary care franchise. On
19 May 2003, Elan and King agreed to proceed with the transaction on amended
terms and on 12 June 2003 the transaction was completed. Effective upon the
closing of the transaction, all claims under the pending litigation were
released and Elan and King dismissed the litigation with prejudice.

Under the terms of the amended transaction, King paid gross consideration on
closing of $749.8 million, which included the transfer to King of Sonata and
Skelaxin inventory with a value of approximately $40 million and obligations
related to Sonata of $218.8 million that were assumed by King at closing. In
addition, Elan will receive an additional $25.0 million payment on 2 January
2004, contingent on the ongoing patent exclusivity of Skelaxin. Elan will also
receive payments of 5% of net sales of the current formulation of Skelaxin
through 31 December 2005 and, thereafter, beginning in 2006 and continuing
through December 2021, Elan will receive payments of 10% of net sales of the
current formulation of Skelaxin in excess of $50.0 million of net sales
annually. Finally, Elan will receive up to an additional $61.0 million in
milestone payments (comprised of up to $86.0 million in clinical, regulatory
and sales milestones less up to $25.0 million in milestones that Elan is
obligated to pay to a third party) relating to the development of enhanced
formulations of Sonata, contingent on the achievement of certain clinical and
regulatory events.


Pharma Marketing

On 17 January 2003, Elan announced that Pharma Operating had filed a lawsuit in
the Supreme Court of the State of New York against Elan and certain of its
subsidiaries in connection with the risk-sharing arrangement between the
parties. The lawsuit sought, among other things, a court determination that
Pharma Operating's approval would be required in the event of a sale by Elan of
its interest in Sonata to a third party. On 30 January 2003, Elan, Pharma
Operating and its parent, Pharma Marketing, agreed to settle the lawsuit and,
under the terms of the settlement agreement, Pharma Operating dismissed the
litigation between the parties without prejudice. Pursuant


- --------------------------------------------------------------------------------
136


- --------------------------------------------------------------------------------

to the settlement agreement, effective upon the sale of Sonata to King on 12
June 2003, (i) Elan paid Pharma Operating $196.4 million in cash (representing
$225.0 million less royalty payments on all related products paid or due to
Pharma Operating from 1 January 2003 through 12 June 2003) to acquire Pharma
Operating's royalty rights with respect to Sonata and Prialt and (ii) Elan's
maximum purchase price for the remaining products in the arrangement, Zonegran,
Frova and Zanaflex, was reduced to $110.0 million, which will increase at a
rate of 15% per annum from 12 June 2003 (less royalty payments made for periods
after 12 June 2003). The parties also agreed to extend Elan's purchase option
termination date to 3 January 2005 from the original termination date of 30
June 2003.

In connection with the settlement agreement, Elan agreed that it would cause
certain subsidiaries in the United States, Ireland, the United Kingdom,
Germany, France, Spain and Italy to pledge their accounts receivable from
commercial sales of pharmaceutical products and services to Pharma Operating as
collateral to secure Elan's obligations in relation to royalty payments under
the Pharma Marketing arrangement and the settlement agreement. Elan also agreed
that, following the closing of a sale of Sonata, it would grant Pharma
Operating additional collateral to the extent that the aggregate value of the
collateral package, which is to be tested on a quarterly basis, is less than
the maximum purchase price for the royalty rights on Zonegran, Frova and
Zanaflex. On 6 March 2003, EPI and Pharma Operating entered into a security
agreement pursuant to which EPI granted Pharma Operating a first priority
security interest in its accounts receivable from commercial sales of
pharmaceutical products in the United States. On that same date, Elan and
Pharma Operating agreed to the terms of the additional collateral mechanism. On
20 May 2003, EPL and Pharma Operating entered into a security agreement
pursuant to which EPL granted Pharma Operating a security interest in its
accounts receivable from commercial sales of pharmaceutical products and
services in the United Kingdom. A similar agreement was entered into in
relation to Ireland by Elan Pharma Limited (Ireland) on 10 June 2003.
Negotiations have not yet begun for Germany, France, Spain or Italy. The
parties have agreed that each of the security agreements will provide for the
release of Pharma Operating's lien on any accounts receivable of a product or
service in which Elan disposes of all or a substantial portion of its rights.
Accordingly, Elan does not expect that any of the security arrangements with
Pharma Operating will limit Elan's ability to dispose of assets in connection
with the recovery plan.


Xcel

On 1 April 2003, Elan announced that it received $89.5 million in cash from
Xcel in exchange for all of Elan's shareholding in, and loans to, Xcel. The net
carrying value of the shares and loan notes was written down during 2002 by
$34.5 million.


Ligand

On 28 May 2003, Elan sold 6.4 million shares of Ligand common stock in the open
market for net cash proceeds of $73.0 million. On 11 July 2003, Elan sold its
remaining 5.8 million shares of Ligand common stock to a number of qualifying
institutional investors for net cash proceeds of $65.1 million. Elan will
record a gain in 2003 of $72.3 million in respect of these two transactions.


LYONs

Through 3 June 2003, Elan repurchased an additional $523.7 million in principal
amount at maturity of the LYONs (representing approximately 32% of the
originally issued LYONs) in separate privately negotiated purchases. The
aggregate cost was $310.3 million. This was a discount of approximately 4% to
the accreted value of such LYONs at 14 December 2003 of $322.9 million. After
taking account of all repurchases up to 3 June 2003, the remaining LYONs have
an accreted value at 14 December 2003 of $494.0 million. Elan may purchase
additional LYONs in the future and any such purchases may be material.


Antegren

On 24 July 2003, Elan and Biogen announced that the Phase III induction trial
of Antegren did not meet the primary endpoint of "response" as defined by a
70-point decrease in CDAI at week 10. This result appears to be due to a larger
than expected placebo response rate. However, data from the study indicate that
the biological activity of Antegren was similar to that seen in the Phase II
study published in the New England Journal of Medicine earlier this year.
Additionally, there were no notable differences in the overall rates of side
effects between Antegren and placebo treatment groups through week 12.

The study evaluated 905 patients. The primary endpoint of "response" was
defined as a 70-point decrease in the CDAI score and "remission" was defined as
a CDAI score of less than or equal to 150, both at week 10. Secondary and
tertiary endpoints included "response" and "remission" at other time points
through week 12, "time to remission and response," mean changes in CDAI as well
as quality of life measurements and inflammatory markers (e.g., C-reactive
protein).

ELAN CORPORATION, PLC 2002 ANNUAL REPORT AND FORM 20-F                     137


NOTES RELATING TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

The week 12 response and remission endpoints were significant compared to
placebo as was a secondary endpoint of IBDQ (Inflammatory Bowel Disease
Questionnaire - a validated quality of life measurement) at week 10. Over the
course of the study, the time to remission and, at weeks 6 through 12, mean
changes in CDAI were also significant in Antegren treated patients compared to
those treated with placebo.

There were no notable differences in the overall rates of side effects between
Antegren and placebo treatment groups through week 12. The most common adverse
events seen in the trial were headache, nausea and abdominal pain across both
groups.

The Phase III data will be shared in greater detail with the medical and
scientific community at medical meetings later this year.

Having failed to meet the primary endpoints in the induction trial, we are
unable to predict when and if a filing for regulatory approval in the Crohn's
indication will be made. Additional trials may be required to generate
sufficient data for such a filing that could involve significant delay and
expense.


Debt covenants

As a result of Elan's failure to timely complete and file with the SEC Elan's
Annual Report on Form 20-F for its fiscal year ended 31 December 2002, on 30
June 2003, Elan defaulted under certain covenants contained in the agreements
governing the EPIL II Notes and the Series B and Series C Guaranteed Notes
issued by EPIL III. The covenants required that Elan provide to each of the
holders of such notes Elan's audited consolidated financial statements,
together with an officer's certificate relating thereto, on or prior to 29 June
2003. On 15 July 2003, Elan also defaulted under a covenant contained in the
indenture governing the 7.25% Senior Notes that required Elan to file its 2002
Annual Report on Form 20-F with the SEC on or prior to 15 July 2003.

Commencing on 29 July 2003, Elan received a series of separate agreements from
a majority of the holders of the EPIL II Notes and the holders of the Series B
and Series C Guaranteed Notes waiving compliance by Elan with the applicable
covenants described above. The series of waivers was effective through 5
September 2003. With the completion of this Annual Report and Form 20-F and the
expected filing with the SEC of Elan's 2002 Annual Report on Form 20-F, the
defaults described above will be cured in all respects. In the absence of the
waivers, the defaults under the EPIL II Notes and the Series B and Series C
Guaranteed Notes would have become events of default on 30 July 2003. In the
absence of the completion and filing with the SEC of Elan's 2002 Annual Report
on Form 20-F, the default under the indenture governing the 7.25% Senior Notes
would become an event of default on 16 September 2003.

33 U.S. GAAP INFORMATION


RESTATEMENT

Elan has restated its U.S. GAAP financial results as of and for the fiscal year
ended 31 December 2001 to consolidate EPIL III from its date of establishment
on 15 March 2001. Under U.S. GAAP, EPIL III has historically been accounted for
by Elan as a qualifying special purpose entity and has not, therefore, been
consolidated.

In addition, Elan has adjusted its previously announced unaudited U.S. GAAP
financial information as of and for the fiscal year ended 31 December 2002 to
give effect to the consolidation of EPIL III and to consolidate Shelly Bay, an
entity established by Elan, from 29 June 2002 through 30 September 2002. Shelly
Bay acquired certain financial assets from EPIL III on 29 June 2002. The 2001
restatement and the adjustments to the 2002 U.S. GAAP financial information are
described below.


- --------------------------------------------------------------------------------
142



- --------------------------------------------------------------------------------

Under Irish GAAP, EPIL III has been accounted for as a consolidated subsidiary
since its date of establishment in accordance with the requirements of FRS 5.
Therefore, the 2001 restatement does not affect the Irish GAAP financial
information contained in this Annual Report and Form 20-F.


Background

In March 2001, Elan transferred a portfolio of equity and debt securities to
EPIL III, a wholly owned subsidiary of Elan. EPIL III issued $160.0 million in
aggregate principal amount of Series A Guaranteed Notes, $190.0 million in
aggregate principal amount of Series B Guaranteed Notes and $200.0 million in
aggregate principal amount of Series C Guaranteed Notes. The Series A Guaranteed
Notes matured on 29 June 2002. To fund the repayment of the notes, on 29 June
2002 EPIL III transferred certain financial assets, consisting of certain of the
securities included in the portfolio transferred to EPIL III, to Shelly Bay and
Shelly Bay made a $148.0 million cash payment to EPIL III. EPIL III used the
proceeds from the payment by Shelly Bay, together with existing cash of $12.0
million, to repay the Series A Guaranteed Notes.


The documents that established EPIL III required that EPIL III dispose of
financial assets in order to repay the Series A Guaranteed Notes at maturity.
The documents also mandated the order in which the assets were to be sold prior
to the maturity date for the Series A Guaranteed Notes. However, due to a number
of factors, including the inability of Elan and EPIL III to locate the list
mandating the order of disposal of the financial assets, the disposal process
was commenced and completed over the one-week period ending on 29 June 2002.
Although Elan, as servicing agent for EPIL III, contacted a number of third
parties regarding their potential interest in purchasing financial assets from
EPIL III, each of those parties indicated that they would not be able to
complete a due diligence analysis of the issuers of the financial assets to be
sold, or to receive all necessary internal approvals to complete the purchase,
on a timely basis.


Therefore, in an effort to enable EPIL III to dispose of the financial assets,
Elan determined that it would be necessary to provide non-recourse credit
support to third parties who would agree to purchase financial assets from EPIL
III. Credit support was offered to a number of potential purchasers of the
financial assets. However, ultimately, only Shelly Bay possessed the ability to
complete the transaction on a timely basis.

Elan established Shelly Bay specifically for the purpose of acquiring financial
assets from EPIL III. All of the capital stock of Shelly Bay was issued to its
sole shareholder. Elan did not own any capital stock of Shelly Bay and did not
have a representative on Shelly Bay's board of directors. In addition, the sole
shareholder of Shelly Bay had no previous contact with Elan. However, as further
described below, Elan possessed all of the financial risk of the Shelly Bay
transaction. Similar to all other potential purchasers contacted by Elan, the
sole shareholder of Shelly Bay was unwilling to invest capital to acquire the
financial assets until a due diligence analysis of the issuers of the financial
assets had been completed. Therefore, the sole shareholder of Shelly Bay made no
substantive capital investment in Shelly Bay and, although Shelly Bay possessed
all of the potential financial benefits of the transaction, neither Shelly Bay
nor its sole shareholder had any financial risk in the transaction.

Elan believed that any failure by EPIL III to dispose of financial assets prior
to 29 June 2002 could potentially adversely impact the non-consolidated
accounting status of EPIL III under U.S. GAAP and could result in defaults under
Elan's debt instruments.

Transaction structure

Under the terms of the transaction, Shelly Bay acquired certain financial assets
from EPIL III on 29 June 2002 and made a cash payment to EPIL III of $148.0
million. Shelly Bay financed the entire purchase price of the financial assets,
together with the funds necessary to pay interest and other costs on the loan to
its maturity date, through borrowings under a $153.0 million non-recourse bank
loan facility maturing on 30 September 2002. Elan provided a full and
unconditional guarantee to the bank to support Shelly Bay's obligation to repay
the loan and provided $153.0 million in cash collateral to the bank to secure
Elan's obligations under its guarantee. Upon the closing of the transaction,
Elan paid to Shelly Bay approximately $1 million to reimburse Shelly Bay for the
expenses expected to be incurred by it in connection with the transaction. In
addition, Elan irrevocably waived all rights of recourse against Shelly Bay in
the event that it failed to repay the bank loan at maturity.

The cash payment made by Shelly Bay in connection with its acquisition of the
financial assets was based upon a valuation conducted by Elan. The valuation
utilised customary, widely-accepted valuation methodologies and required that
Elan make certain judgements and assumptions regarding the financial assets.
Elan did not receive any independent verification of the valuation at the time
of the transaction. In addition, EPIL III did not receive any bids for the
financial assets to be disposed of.

Upon the closing of the transaction, Shelly Bay's assets consisted solely of the
financial assets purchased from EPIL III. Under the terms of the transaction,
Shelly Bay was required to complete a due diligence analysis of the issuers of
the securities prior to 15 September 2002.

ELAN CORPORATION, PLC 2002 ANNUAL REPORT AND FORM 20-F                     143



NOTES RELATING TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

Shelly Bay had the right to either elect, on or prior to 15 September 2002, to
retain the financial assets on a long-term basis or to dispose of the financial
assets prior to 30 September 2002.

In the event that Shelly Bay elected to retain the financial assets, it was
required, within 15 days of the election, to obtain alternative financing in an
amount equal to the value, as of 29 June 2002, of the assets being retained, as
determined by an independent appraiser engaged by Shelly Bay. The net cash
proceeds received by Shelly Bay from any alternative financing were required to
be applied to repay amounts outstanding under Shelly Bay's bank loan.

In the event that Shelly Bay elected to dispose of the financial assets prior to
30 September 2002, Shelly Bay was required to apply the net proceeds from the
dispositions to repay amounts outstanding under its bank loan. The transaction
agreements contained no limitation on the price at which any financial asset
could be sold by Shelly Bay or the party to whom any financial asset could be
sold. In addition, Elan agreed that it had no right to object to the disposition
of any financial asset, the party to whom it was disposed of or the price
obtained for the disposition.

Given the non-recourse nature of the Shelly Bay bank loan, Elan possessed all of
the financial risk of the transaction under its guarantee of the bank loan, and
the cash collateral provided by Elan to secure the guarantee, in the event of
any shortfall in the aggregate proceeds received by Shelly Bay from the
refinancing or disposition of the financial assets. Although Shelly Bay
possessed all of the potential financial benefits of the transaction, neither
Shelly Bay nor its sole shareholder had any financial risk in the transaction.

As required by the terms of the transaction, Shelly Bay engaged an independent
appraiser to value the financial assets as of 29 June 2002. The appraisal, which
was prepared in early September 2002, valued the financial assets at $8.2
million.

Shelly Bay did not elect, under the terms of the transaction, to retain any of
the financial assets and obtain alternative financing in an amount equal to the
independent appraiser's valuation. Rather, by 30 September 2002, Shelly Bay had
disposed of all of the financial assets for aggregate net proceeds of $9.3
million. A number of the financial assets were disposed of, for net proceeds of
$1.8 million, to an affiliate of Shelly Bay. The remainder of the financial
assets were sold to third parties and in open market transactions. As described
above, the transaction agreements contained no limitation on the price at which
any financial asset could be sold by Shelly Bay or the party to whom any
financial asset could be sold, including to an affiliate of Shelly Bay. In
addition, Elan agreed that it had no right to object to the disposition of any
financial asset, the party to whom it was disposed of or the price obtained for
the disposition.

As a result of the disposition of the financial assets by Shelly Bay for
aggregate net proceeds of $9.3 million, on 30 September 2002, Elan made a cash
payment of $141.6 million to satisfy its obligation under its guarantee. Under
the terms of the transaction agreements, Elan has no further obligation under
the guarantee and has no recourse to Shelly Bay or to its sole shareholder
arising from Elan's payment under the guarantee.

Restatement of previously reported U.S. GAAP financial results

Elan has restated its U.S. GAAP financial results to consolidate EPIL III from
its date of establishment on 15 March 2001. The manner in which the Shelly Bay
transaction was completed, including Elan's facilitation of the transaction,
which resulted in an intercompany transfer of financial assets by EPIL III to
Shelly Bay at a price above fair value, demonstrated that Elan possessed the
ability to control EPIL III. This ability to control EPIL III was inconsistent
with SFAS No. 125 "Accounting for Transfers and Servicing of Financial Assets
and Extinguishment of Liabilities" and EITF Topic D-66 "Effects of a
Special-Purpose Entity's Powers to Sell, Exchange, Repledge, or Distribute
Financial Assets under SFAS Statement No. 125".

Adjustment of previously announced unaudited U.S. GAAP financial information for
2002

Elan has also adjusted its previously announced unaudited U.S. GAAP financial
information for 2002 to give effect to the consolidation of EPIL III and to
consolidate Shelly Bay from 29 June 2002 through 30 September 2002 under EITF
D-14 "Transactions involving Special Purpose Entities" ("D-14"). Elan
established Shelly Bay. The sole shareholder of Shelly Bay did not make a
substantive capital investment in Shelly Bay and neither Shelly Bay nor its sole
shareholder possessed any financial risk in the transaction. Elan possessed the
financial risk associated with the Shelly Bay transaction until 30 September
2002. Under D-14, these factors require that Elan consolidate Shelly Bay from 29
June 2002 through 30 September 2002.

The following tables present the effects of consolidating EPIL III on Elan's
previously reported U.S. GAAP net (loss)/income, shareholders' equity, total
assets, total liabilities and cash flows for 2001 and the effects of
consolidating EPIL III and Shelly Bay on Elan's previously announced unaudited
U.S. GAAP financial information for 2002:

DIFFERENCES BETWEEN IRISH AND U.S. ACCOUNTING PRINCIPLES


U.S. GAAP income statement data, comprehensive income statement data, balance
sheet data and cash flow data have been provided on pages 161 to 163 for the
benefit of U.S. investors. These incorporate the restatement described above for
EPIL III.

The financial statements of Elan have been prepared in accordance with Irish
GAAP, which differ in certain significant respects from U.S. GAAP. The
presentation of information also differs. For example, exceptional items are
separately disclosed within their statutory classifications under Irish GAAP,
while U.S. GAAP does not provide for the characterisation of items as
exceptional. The material differences as they apply to Elan's financial
statements are as follows:

A    BUSINESS COMBINATIONS

1. Dura: On 9 November 2000, Elan completed a merger with Dura. At the time of
this merger, Irish and U.S. GAAP had different criteria for establishing the
method of accounting required for business combinations.

o    Under U.S. GAAP, the merger with Dura required the application of the
     pooling of interests method of accounting. The assets and liabilities of
     Dura and Elan were combined and carried forward to the merged enterprise at
     their pre-combination recorded amounts. Therefore, under U.S. GAAP, no
     goodwill arose from the merger of Dura and Elan. The income statements of
     Dura and Elan for 2000 and prior years were combined and reported as income
     statements of the merged enterprise. The costs of the transaction were
     expensed.

o    Under Irish GAAP, the acquisition of Dura by Elan was accounted for using
     acquisition accounting. The cost of the investment in Dura was calculated
     based on the fair value of the shares issued, together with the related
     transaction costs. The assets and liabilities of Dura were recorded based
     on their fair values at the date of acquisition. The difference between the
     cost of the investment and the fair value of the assets and liabilities of
     Dura was recorded as goodwill. Until 1 October 2002, this goodwill was
     being amortised over twenty years. This estimated useful life was reduced
     to 10 years effective 1 October 2002. Pre-acquisition results for both
     companies were not combined. The profit and loss accounts have been
     consolidated for the post-acquisition period only.

The differences in accounting for the Dura transaction between Irish and U.S.
GAAP resulted in the following reconciling items:


o    A goodwill amortisation expense arose under Irish GAAP. The goodwill
     amortisation expense for 2002, 2001 and 2000 was $68.9 million, $55.2
     million and $9.6 million, respectively. Accumulated goodwill amortisation
     at 31 December 2002 amounted to $133.7 million. No goodwill amortisation
     expense arose under U.S. GAAP;

o    In accordance with FRS 11, Elan performed an impairment review of the
     goodwill arising from the acquisition of Dura under Irish GAAP. This review
     was undertaken at 31 December 2002. As a result of this review, Elan
     recorded an impairment charge of $854.9 million for 2002, reducing the
     carrying value of the Dura goodwill to $123.1 million (net of accumulated
     goodwill amortisation of $133.7 million) at 31 December 2002. For a more
     detailed description of this impairment, please refer to Note 3 to the
     Consolidated Financial Statements. Under U.S. GAAP, no goodwill arose from
     the merger of Dura and Elan;

o    The exclusion of pre-acquisition profits and losses under Irish GAAP
     compared to the combination of historic income statements under U.S. GAAP
     resulted in a reconciling item of $0.4 million between Irish and U.S. GAAP
     net income/(loss) for 2001, being losses on managed funds recorded by Dura
     in 2001 which related to pre-acquisition balances. The exclusion of
     pre-acquisition profits and losses under Irish GAAP compared to the
     combination of historic income statements under U.S. GAAP resulted in a
     reconciling item of $32.8 million between Irish and U.S. GAAP net
     income/(loss) for 2000;


- --------------------------------------------------------------------------------
ELAN CORPORATION, PLC 2002 ANNUAL REPORT AND FORM 20-F                     147



NOTES RELATING TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

o    The expensing of transaction costs in 2000 under U.S. GAAP resulted in a
     reconciling item of $35.1 million between Irish and U.S. GAAP net
     income/(loss) for 2000;

o    A portion of outstanding Dura debt was repaid in December 2000 under a
     change of control clause. On the date of acquisition, Dura had $2.7 million
     in unamortised financing costs relating to this debt. This represented a
     fair value adjustment under Irish GAAP and it increased goodwill by $2.7
     million. Under U.S. GAAP, the $2.7 million was expensed in the income
     statement for 2000;

o    Goodwill arising under Irish GAAP, on the acquisition of Dura, resulted in
     a reconciling difference to shareholders' equity of $256.8 million at 31
     December 2002 (2001: $1,111.7 million). In addition, the accumulated Irish
     GAAP goodwill amortisation expense at 31 December 2002 of $133.7 million
     does not arise under U.S. GAAP.

o    Under Irish GAAP, FRS 7, "Fair Values in Acquisition Accounting", requires
     that any adjustments to the provisional fair values allocated at the date
     of acquisition should be incorporated in the financial statements for the
     first full financial year following the acquisition. This resulted in a
     balance sheet reallocation of $52.9 million in 2001 relating to the
     finalisation of the fair values of product intangibles. This did not arise
     under U.S. GAAP, as pooling of interests accounting did not result in such
     adjustments to fair value; and

o    Dura deferred tax assets with a pre-acquisition basic value of $18.4
     million were eliminated as a fair value adjustment under Irish GAAP. Under
     U.S. GAAP, this amount was expensed in the combined income statement prior
     to 2000. No reconciling difference to either net income/(loss) or
     shareholders' equity arises from this item.

2. Other business combinations: Under Irish and U.S. GAAP, all of Elan's
acquisitions, except for Dura, were accounted for using acquisition (purchase)
accounting.

Under acquisition accounting, Irish and U.S. GAAP require the fair value of the
purchase consideration to be allocated to the net assets acquired based on their
fair values on the date of acquisition. The difference between the fair value of
the purchase consideration and the fair value of the net assets acquired is
goodwill. Under U.S. GAAP, the fair value of equity securities issued to effect
a purchase business combination is determined based on the market price of the
equity securities over a reasonable period of time before and after the proposed
transaction is announced. Under Irish GAAP, the fair value of shares issued is
determined based on the market price of these shares at the acquisition date.
There were no material differences between the fair value of shares issued by
Elan to effect purchase business combinations under Irish and U.S. GAAP for the
periods presented.

Under U.S. GAAP, the fair values of acquired IPR&D assets were expensed
immediately in the income statement. The amounts were capitalised and treated as
either goodwill or acquired IP under Irish GAAP. IPR&D expenses were $Nil for
2002 and 2001, and $246.0 million for 2000. The difference in shareholders'
equity between Irish and U.S. GAAP, arising from the expensing of IPR&D, under
U.S. GAAP, was $2,121.1 million at 31 December 2002 (2001: $2,121.1 million).
Under Irish GAAP, Elan has subsequently incurred impairment charges to such
goodwill and acquired IP. As these amounts were previously expensed as IPR&D,
under U.S. GAAP, such impairment charges have resulted in reconciling
differences between Irish and U.S. GAAP net income/(loss). These impairment
charges were $249.6 million, $785.2 million and $Nil for 2002, 2001 and 2000,
respectively. This resulted in a difference in shareholders' equity between
Irish and U.S. GAAP of $1,034.8 million at 31 December 2002 (2001: $785.2
million). For additional information regarding intangible assets, please refer
to Notes 3 and 11 to the Consolidated Financial Statements.

Under Irish GAAP, prior to 31 December 1998, goodwill arising on acquisitions
was immediately written-off to shareholders' equity. Since 1998, in accordance
with FRS 10, "Goodwill and Intangible Assets", goodwill is no longer written-off
immediately to shareholders' equity but is capitalised and amortised over its
useful life. The difference in shareholders' equity between Irish and U.S. GAAP,
arising from goodwill previously written-off immediately against reserves, was
$574.3 million at 31 December 2002 (2001: $574.3 million).

Under U.S. GAAP, Elan adopted SFAS No. 142, "Goodwill and Other Intangible
Assets" ("SFAS No. 142"), effective 1 January 2002. Prior to this date,
intangible assets, including goodwill, were amortised over their estimated
useful lives. SFAS No. 142 requires that goodwill and other intangible assets
with indefinite lives are no longer amortised but instead tested for impairment
at least annually. The difference in net loss between Irish and U.S. GAAP,
arising from the amortisation of intangible assets (mainly goodwill and acquired
IP) in 2002 was $113.9 million, of which $68.9 million related to Dura.

There are differences between Irish and U.S. GAAP in the manner by which the
carrying value of goodwill is allocated for purposes of calculating the profit
or loss upon a disposal of a business. Under Irish GAAP, the carrying value of
goodwill is allocated based on the relative fair value of the business being
disposed of to the total fair value of the acquisition. This is based on
relative fair values on the date of acquisition. Under U.S. GAAP, SFAS No. 142
requires that the allocation is determined based on the relative fair value of
the business being disposed of to the fair value of that component of the
reporting unit being retained. This is based on relative fair values on the date
of disposal. During 2002, Elan disposed of Abelcet which had been acquired
through the acquisition of Liposome. Abelcet formed part of the Core Elan
reporting unit.


- --------------------------------------------------------------------------------
148


- --------------------------------------------------------------------------------

Under Irish GAAP, goodwill of $119.0 million was expensed arising from the sale
of the Abelcet business in 2002. Under U.S. GAAP, goodwill of $19.0 million was
expensed arising from the sale of the Abelcet business in 2002. This resulted in
a reconciling difference of $100.0 million between Irish and U.S. GAAP net loss
for 2002.


B    IMPAIRMENT OF GOODWILL/ACQUIRED IP

Under Irish GAAP, FRS 11 requires that intangible assets are reviewed for
impairment if there is an indication that a reduction in value may have
occurred. As described in Notes 3 and 11 to the Consolidated Financial
Statements, Elan recorded impairment charges to goodwill and acquired IP of
$337.9 million in 2002. These amounts are in addition to the charge of $854.9
million also recorded in 2002, for the impairment to the carrying value of the
goodwill arising from the acquisition of Dura. Under U.S. GAAP, $88.3 million of
the $337.9 million was also expensed in 2002. Under U.S. GAAP, the remaining
$249.6 million of the $337.9 million was expensed as IPR&D prior to 2002. Hence
this amount was a reconciling difference between Irish and U.S. GAAP net loss
for 2002.

The total impairment charges to acquired IP were $785.2 million under Irish GAAP
for 2001. Under U.S. GAAP, all of this amount was expensed as IPR&D prior to
2001. Hence this amount was a reconciling difference between Irish and U.S. GAAP
net income/(loss) for 2001.


C    IMPAIRMENT OF OTHER INTANGIBLE ASSETS

Under U.S. GAAP for 2002, in accordance with SFAS No. 144 "Accounting for the
Impairment or Disposal of Long-Lived Assets" ("SFAS No. 144") and prior periods
(under SFAS No. 121 "Accounting for the Impairment of Long-Lived Assets and for
Long-Lived Assets to Be Disposed Of"), intangibles are assessed for impairment
based on undiscounted cash flows. If the estimated future non-discounted cash
flows indicate that an impairment had arisen, the amount of the impairment was
then measured using projected future discounted cash flows. Under Irish GAAP,
the carrying value of an intangible asset is compared to its discounted cash
flows for purposes of assessing whether an impairment has arisen.

In 2001, Elan recorded an impairment charge of $44.4 million on Myambutol under
Irish GAAP, as the estimated future discounted cash flows were less than the
carrying value for this intangible. Under U.S. GAAP, no impairment charge arose
in 2001 as the estimated future undiscounted cash flows were greater than the
carrying value for this intangible.

In 2002, Elan recorded an impairment charge of $44.4 million on Myambutol under
U.S. GAAP, as the projected future cash flows had decreased such that the
estimated future undiscounted cash flows were less than the carrying value for
this intangible asset. As discussed above, Elan had recorded an equivalent
impairment charge in 2001 under Irish GAAP.


D    ACCOUNTING FOR DERIVATIVES

Under Irish GAAP, Elan marks free-standing derivative instruments to market at
each balance sheet date and the resulting gains and losses are recognised in the
profit and loss account. The carrying values of derivative financial instruments
are generally reported within current assets or other current liabilities.

Under U.S. GAAP, SFAS No. 133 became effective in 2001. SFAS No. 133 requires
that derivatives are recognised as either assets or liabilities and measured at
fair value. Changes in the fair value of derivatives are recorded each period in
current earnings or other comprehensive income, depending on whether the
derivative is designated as part of a hedge transaction and, if it is, the type
of hedge transaction.

The definition of a derivative instrument is significantly broader under U.S.
GAAP than under Irish GAAP. This gives rise to a reconciling difference, as
certain financial assets and liabilities are accounted for as derivative
instruments under U.S. GAAP and are not accounted for as derivative instruments
under Irish GAAP. The adoption of SFAS No. 133 in 2001 had a cumulative after
tax income impact under U.S. GAAP of $7.8 million relating to embedded
derivatives and free-standing warrants. The fair value of these derivative
instruments at 31 December 2002 was $34.9 million (2001: $52.9 million).

The difference in net (loss)/income between Irish and U.S. GAAP arising from the
accounting for derivatives amounted to $(4.4) million, $3.8 million and $Nil for
2002, 2001 and 2000, respectively, resulting in a reconciling difference to
shareholders' equity of $7.2 million (2001: $11.6 million).

In 2002 and 2001, Elan exercised its option to convert debt in Ligand into
common shares of Ligand. Under Irish GAAP, gains of $10.1 million and $17.7
million were recognised for 2002 and 2001 in the profit and loss account
representing the excess in the value of the


- --------------------------------------------------------------------------------

NOTES RELATING TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

equity financial instrument received over the carrying value of the convertible
debt. Since 1 January 2001, under U.S. GAAP, Elan has accounted for the
convertible debt in Ligand in accordance with the requirements of SFAS No. 133,
as the conversion option constituted an embedded derivative. As such, changes in
fair value of $3.2 million and $20.7 million were recorded as income during 2002
and 2001, respectively. The cumulative catch up adjustment for the
implementation of SFAS No. 133, recorded at 1 January 2001, included a
cumulative gain of $3.9 million with respect to Ligand convertible debt.


E    ACQUIRED PRODUCT RIGHTS AND FINANCE CHARGES

Under Irish GAAP, contingent and potential acquisition payments which are likely
to be made in the future are recognised as creditors. Such contingent payments
on product acquisitions and alliances are capitalised and recorded as creditors
on a time discounted basis. A corresponding finance charge is recorded annually
in the profit and loss account. Under U.S. GAAP, such payments are not
recognised in the financial statements until the related contingencies are
resolved. This resulted in a difference between Irish GAAP and U.S. GAAP net
(loss)/income of $19.2 million, $34.6 million and $Nil for 2002, 2001 and 2000,
respectively, consisting of finance and amortisation charges. The difference in
shareholders' equity between Irish and U.S. GAAP was $53.8 million at 31
December 2002 (2001: $34.6 million).


F    REVENUE RECOGNITION

Contract revenue, including research revenues and licence fees, arises from
contracts related to research and development activities on behalf of clients
and/or technology licensing and business ventures. Under Irish GAAP,
non-refundable up-front licence fee revenue is recognised when earned and when
the licensor has no future legal obligation pursuant to the licence fee.
Refundable licence fees are treated as deferred revenue until such time as they
are no longer refundable.

Under U.S. GAAP, the accounting treatment adopted by Elan for non-refundable
up-front licence fees was similar to Irish GAAP prior to 2000. In December 1999,
the SEC issued SAB 101. SAB 101 provides guidance on revenue recognition and
related disclosures in financial statements. SAB 101 generally requires deferral
and amortisation of up-front licence fees where there is a continuing
involvement with the licensed asset through the provision of research and
development services, manufacturing services or other similar activities. SAB
101 also applies to up-front fees other than licence fees. Elan adopted SAB 101
in 2000.

Following the adoption of SAB 101, under U.S. GAAP, Elan defers and amortises
up-front licence fees to the income statement over the "performance period". The
performance period is the period over which Elan expects to provide services to
the licencee. It is determined by the provisions of, and by the facts and
circumstances of, the relevant contract. Generally, milestone payments have been
treated similarly under both Irish GAAP and U.S. GAAP. They have been recognised
when earned and non-refundable, and when Elan has no future legal obligation
pursuant to the milestone payment. However, the actual accounting for milestones
depends on the facts and circumstances of each contract. Elan applies the
substantive milestone method in accounting for milestone payments under U.S.
GAAP. This method requires that substantive effort must have been applied to
achieve the milestone prior to revenue recognition. If substantive effort has
been applied, the milestone is recognised as revenue, subject to it being
earned, non-refundable and not subject to future legal obligation. This requires
an examination of the facts and circumstances of each contract. Substantive
effort may be demonstrated by various factors, including the risks associated
with achieving the milestone, the period of time over which effort was expended
to achieve the milestone, the economic basis for the milestone payment and
licensing arrangement and the costs and staffing to achieve the milestone. It is
expected that the substantive milestone method will be appropriate for most
contracts. If Elan determines the substantive milestone method is not
appropriate, Elan will apply the performance method to the relevant contract
under U.S. GAAP. This method recognises as revenue the percentage of cumulative
non-refundable cash payments earned under the contract, based on the percentage
of costs incurred to date compared to the total costs expected under the
contract. This is subject to the milestone being earned, non-refundable and not
subject to future legal obligation.

Elan implemented SAB 101 in the fourth quarter of 2000. For the year ended 31
December 2000, Elan recorded a non-cash charge of $344.0 million under U.S. GAAP
for the cumulative effect of this accounting change relating to revenue
recognised in periods up to 31 December 1999. The difference in shareholders'
equity between Irish and U.S. GAAP, arising from the application of SAB 101
under U.S. GAAP, was $254.3 million at 31 December 2002 (2001: $316.1 million).

The performance period was typically between two and three years for
non-refundable up-front license fees received by Elan from business ventures
pursuant to Elan's business venture programme. The performance period was
determined by the facts and circumstances and could have been shorter or longer
in duration than the typical two to three year period. Under U.S. GAAP, Elan
recognised $203.8 million, $255.0 million and $197.2 million in licence fee
revenue from business ventures in 2002, 2001 and 2000, respectively.


- --------------------------------------------------------------------------------

- --------------------------------------------------------------------------------

Total contract revenue recognised under Irish GAAP was $128.5 million, $333.7
million and $476.4 million in 2002, 2001 and 2000, respectively. Under U.S.
GAAP, Elan recognised $353.9 million, $430.2 million and $474.8 million of
contract revenue in 2002, 2001 and 2000, respectively, comprising amortised
licence fee revenue of $234.7 million, $287.2 million and $306.2 million,
respectively. Of these amounts, $45.2 million, $88.6 million and $155.4 million
of the revenue in 2002, 2001 and 2000, respectively, were included as part of
the SAB 101 cumulative adjustment.

Under Irish GAAP, revenue from the sale of product rights and related inventory
is recognised when earned and non-refundable. The same accounting is generally
applicable under U.S. GAAP. However, in certain circumstances, such as when Elan
manufactures the product, deferral and amortisation of such revenue may be
appropriate. Elan has deferred and is amortising the revenue received on the
disposal of certain products, principally Avinza, Actiq and nifedipine during
2002. Elan manufactures Avinza and nifedipine. The amounts of deferred revenue
under U.S. GAAP for Avinza, Actiq and nifedipine are $96.7 million, $12.7
million and $40.5 million, respectively, at 31 December 2002. Elan recognised
$37.6 million of product revenue under U.S. GAAP from these products in 2002.
The deferred revenue on Actiq was fully amortised in the first quarter of 2003.
Elan continues to manufacture Avinza and nifedipine and is amortising these
deferred revenue balances over 4 and 5 years, respectively. Under Irish GAAP,
Elan recognised $154.7 million of product revenue from these product disposals.

Total revenue under U.S. GAAP was higher than Irish GAAP by $122.1 million and
$121.8 million for 2002 and 2001, respectively.

This difference in revenue mainly arose due to:

o    $61.8 million and $98.6 million for 2002 and 2001, respectively, relates to
     the application of SAB 101 under U.S. GAAP. SAB 101 does not apply under
     Irish GAAP;

o    $1.6 million and $19.7 million for 2002 and 2001, respectively, relates to
     the differences in the application of the equity method of accounting
     between Irish and U.S. GAAP; and

o    $58.7 million for 2002 relates to differences in the carrying value of
     intangibles assets disposed. The revenue on products disposed of is based
     on the consideration received less the carrying value of the intangible
     asset.

The following table shows these reconciling differences in revenue between Irish

G    NON-CONSOLIDATED SUBSIDIARIES (EPIL / EPIL II)

Under Irish GAAP, EPIL and EPIL II have been consolidated as subsidiaries of
Elan. Elan owns 100% of the equity in the companies. The individual investments
held by EPIL and EPIL II have remained on Elan's balance sheet and the related
loan notes of each of the companies have been included as a liability. Elan
expensed the related interest charge in the profit and loss account.

Under U.S. GAAP, EPIL II has not been consolidated as a subsidiary of Elan. EPIL
has been consolidated as a subsidiary of Elan under U.S. GAAP from March 2001
when control of EPIL reverted to Elan. Prior to this date, it was not
consolidated. EPIL (prior to March 2001) and EPIL II qualify as special purpose
entities within the meaning of SFAS No. 125, as grandfathered under SFAS No.
140, as Elan has effected a true legal sale of the investments and has not
retained control over such assets. Accordingly, the transfer of investments to
EPIL (prior

to March 2001) and EPIL II was treated as a sale of the assets at fair value
under U.S. GAAP and the related loan notes have not been included as a
liability. Elan has not expensed the related interest charge in the income
statement.

EPIL's qualifying special purpose entity status was established in June 1999.
EPIL issued $350.0 million of loan notes with a maturity date of June 2002. EPIL
II's qualifying special purpose entity status was established in June 2000. EPIL
II issued $450.0 million of loan notes with a maturity date of June 2004. In
March 2001, pursuant to an exchange offer and consent solicitation, EPIL III
offered to exchange its Series A Guaranteed Notes and Series B Guaranteed Notes
for all the loan notes previously issued by EPIL in June 1999. The consent
solicitation requested consents from the holders of EPIL's loan notes to amend
the agreements under which these notes were issued. These amendments removed
restrictions on EPIL, including those relating to entering into transactions
with affiliates, merging, changing its business, amending its charter documents,
selling assets or making investments. The acceptance of the exchange offer and
consent solicitation by all of EPIL's note holders caused control of EPIL to
revert to Elan. Effectively upon closing of the exchange offer and consent
solicitation, EPIL's qualifying status terminated and EPIL was consolidated by
Elan under U.S. GAAP.

Elan holds a retained interest in EPIL II through its ownership of the retained
beneficial interest (100% of the common stock). The retained beneficial interest
entitles Elan to any residual proceeds in EPIL II after repayment of the EPIL II
Notes. Pursuant to the Stock Pledge Agreement, Elan has pledged the common stock
in EPIL II to the noteholders of EPIL II. The holders of the loan notes have
control of key voting rights, such as the right to approve the appointment of
directors of EPIL II and the right to approve amendments to the Memorandum of
Association and By-Laws of EPIL II. The board of directors of EPIL II is
independent of Elan and is comprised of a majority of independent directors and
one director appointed by Elan. EPIL II may dispose of financial assets upon
maturity of its loan notes. Upon the maturity of the loan notes due 2004, if
there are more than sufficient financial assets to repay the loan notes, the
organisational documents of EPIL II do not contain provisions concerning the
selection of financial assets, or the amount of financial assets, to be disposed
of. In this situation, any decision as to which assets to dispose of would be
made by the board of directors of EPIL II. When the loan notes of EPIL II are
repaid, the Stock Pledge Agreement terminates and Elan is entitled to the
residual proceeds, if any, through ownership of the common stock in EPIL II.
Elan does not have a call option or similar unilateral legal right over the
transferred investments. Elan has provided a direct guarantee to the holders of
the loan notes of EPIL II for the repayment of the loan notes and the payment of
any unpaid interest. In the event that EPIL II does not meet its obligations to
pay amounts due to the noteholders, the noteholders may call upon the Elan
guarantee.

Elan's accounting policy is to allocate the previous carrying amount of the
financial assets transferred, between the financial assets transferred and the
retained interest based on their relative fair values on the date of transfer.
The fair value of a retained interest, both for initial and subsequent
measurement, is calculated as the fair value of the qualifying special purpose
entity's assets less the fair value of its liabilities. For disclosure purposes,
the fair value of the assets of EPIL II is estimated using established financial
methodologies, including quoted market prices, where available, and takes into
account the time value of money. The fair value of investments in private
entities and non-traded securities of public entities is typically measured by
valuation methodologies such as option-pricing models and valuations achieved in
recent private placements by the investee. The key assumptions used in measuring
the fair value of Elan's retained interest in EPIL II are common stock prices
for equity-based assets and the discount rate used for debt-based assets. The
fair value of the liabilities of EPIL II is measured as the total amount
outstanding under its loan notes, including accrued but unpaid interest (if
any), and takes into account the time value of money. The fair value of the
guarantee was measured as de minimis on the transfer date. The guarantee has
subsequently been accounted for, under U.S. GAAP, as a loss contingency in
accordance with the requirements of SFAS No. 5, "Accounting for Contingencies".
This requires that Elan record a charge under the guarantee if it is probable
that a payment will be made under the guarantee to the EPIL II noteholders.

Elan's retained interest in EPIL II had a fair value of $Nil on the transfer
date. Elan is carrying the common stock of EPIL II at cost, as it does not
qualify as a debt security or a debt-like security as defined in SFAS No. 115
"Accounting for Certain Investments in Debt and Equity Securities" ("SFAS No.
115").

On 31 December 2002, the estimated fair value of Elan's retained interest in
EPIL II was $Nil. Elan has guaranteed the debt of EPIL II, to the extent that
the investments held by it are insufficient to repay the debt when it falls due
in 2004. At 31 December 2002, Elan had recorded a provision of $295.4 million
under U.S. GAAP in respect of this guarantee. An adverse change of 10% (20%) in
the common stock prices used to estimate the fair value of equity-based assets
held by EPIL II would result in a decline of $4.3 million ($8.5 million) in the
estimated fair value of the investment portfolio of EPIL II. An adverse change
of 10% (20%) in the annual discount rate used to estimate the fair value of
debt-based assets held by EPIL II would result in a decline of $3.8 million
($7.1 million) in the estimated fair value of the investment portfolio of EPIL
II.

The sensitivities outlined above regarding the fair value of Elan's retained
interest in EPIL II are hypothetical and should be used with caution. As the
figures indicate, changes in fair value based on a 10% variation in an
assumption generally cannot be extrapolated


- --------------------------------------------------------------------------------
152


- --------------------------------------------------------------------------------

because the relationship of the change in assumption to the change in fair value
may not be linear. Also, in the sensitivities outlined above, the effect of a
variation in a particular assumption on the fair value of the retained interest
is calculated without changing any other assumption. In reality, changes in one
factor may result in changes in another, which may magnify or counteract the
sensitivities. For example, increases in market interest rates may result in
declines in market common stock prices.

Elan provides services such as bookkeeping and administration, monitoring,
administering compliance with applicable laws and regulations and custodian
service to EPIL II. Such services are for the benefit of EPIL II. All
compensation paid to Elan represents an arms-length price for those services. In
2002, Elan received a fee of $Nil (2001: $0.2 million, 2000: $0.7 million) and
$0.8 million (2001: $0.8 million, 2000: $0.4 million) for providing these
services to EPIL and EPIL II, respectively.

Net loss under U.S. GAAP was higher by $154.8 million in 2002 and net income was
higher by $90.9 million and $38.9 million for 2001 and 2000, respectively, than
under Irish GAAP. The differences between U.S. and Irish GAAP due to EPIL and
EPIL II are as follows:

- -----------------------------------------------------------------------------------------------------------------------


These net reconciling differences between Irish and U.S. GAAP arose mainly due
to profits on disposals, interest charges and impairment charges.

There was no gain or loss to Elan arising from the disposal of investments to
EPIL in 1999. Under U.S. GAAP, there was a gain of $39.2 million to Elan arising
from the disposal of investments to EPIL II in June 2000. No gain or loss was
recognised upon the termination of EPIL's qualifying special purpose entity
status in March 2001. Under Irish GAAP, as these are consolidated subsidiaries,
such gains are not included in Elan's profit and loss account.

Under Irish GAAP, the interest charges recorded for the EPIL and EPIL II loan
notes were $43.0 million, $49.1 million and $51.6 million for 2002, 2001 and
2000, respectively. Under U.S. GAAP, such charges are not recorded in Elan's
income statement.


H    ASSOCIATE ACCOUNTING

The difference between Irish and U.S. GAAP net (loss)/income arising from
differences in the application of the equity method of accounting, was $(3.8)
million, $13.0 million and $Nil for 2002, 2001 and 2000, respectively.

Most of the difference arises on the accounting for Elan's investment in Amarin.
Under U.S. GAAP, Elan's investment in Amarin was accounted for using the equity
method in 2002 based on the percentage of voting equity shares held by the
Group. Under Irish GAAP, the investment was accounted for using the equity
method in 2002 based on the percentage of stock held on a fully diluted basis
including non-voting convertible preference shares. This resulted in a
reconciling item to the net (loss)/income of $(3.8) million between U.S. and
Irish GAAP in 2002 (2001: $11.0 million).

Under U.S. GAAP, certain investments of Elan were accounted for under the equity
method of accounting and treated as associates. Under Irish GAAP, these
investments were accounted for under the cost method. These investments were
written-off for the purpose of Irish GAAP in 2001 resulting in a reconciling
item to the net (loss)/income of $Nil (2001: $2.0 million) due to the different
cost basis of the investments.


I    STOCK OPTION COMPENSATION

Elan grants options to employees under its stock option plans. These options are
granted at fixed exercise prices equal to the market value on the date of grant.
Under Irish GAAP, no compensation cost has been accrued for options awarded to
employees as the exercise price has been set equal to the market value on the
date of grant.

ELAN CORPORATION, PLC 2002 ANNUAL REPORT AND FORM 20-F                     153



NOTES RELATING TO FINANCIAL STATEMENTS
- --------------------------------------------------------------------------------

Under U.S. GAAP, Elan applies Accounting Principles Board Opinion No. 25,
"Accounting for Stock Issues to Employees" ("APB 25"). In accordance with APB
25, no compensation cost was initially recognised for stock options granted, as
they have been granted to employees at market value and at a fixed exercise
price. In accordance with Financial Accounting Standards Board ("FASB")
Financial Interpretation No. 44 (FIN No. 44), "Accounting for Certain
Transactions Involving Stock Compensation", a compensation expense has been
recognised under U.S. GAAP where the original terms of a stock option award
were modified. Such modifications result in the fair value of the options being
recognised as a compensation expense over any remaining service period. Elan
recognised a compensation expense of $0.1 million, $0.2 million and $31.8
million in 2002, 2001 and 2000, respectively, arising from modifications. The
modifications included option acceleration upon severance of employees and a
change of status from employees to non-employees. Under Irish GAAP, no
compensation expense arose as a result of such modifications.

Under Irish GAAP, no compensation expense arises as a result of grants to
non-employees. Under U.S. GAAP, options granted to non-employees have been
valued at fair value and the related compensation expense is being amortised
over the life of the option. Elan recognised a compensation expense of $Nil,
$0.3 million and $Nil in 2002, 2001 and 2000, respectively, arising from options
granted to non-employees.


J    PENSIONS

The main differences between Irish and U.S. GAAP in accounting for pension costs
are:

o    Under Irish GAAP, plan assets are valued on the basis of a discounted
     present value of expected future income. U.S. GAAP requires that plan
     assets are valued by reference to their market value.

o    Under Irish GAAP, pension costs in connection with defined benefit plans
     are assessed in accordance with the advice of independent actuaries using
     assumptions and methods which produce the actuaries' best estimates of the
     cost of providing the relevant pension benefits. U.S. GAAP requires the use
     of the projected unit credit method and the matching of the projected
     benefit obligation against the fair value of the plan's assets, as adjusted
     to reflect any unrecognised obligations or assets.

o    Under Irish GAAP, the measurement of plan assets and obligations may be
     based on the most recent actuarial valuation. Under U.S. GAAP, calculations
     must be made as of the date of the financial statements or a date not more
     than three months prior to that date.

o    Under Irish GAAP, pension credits are not recognised in the financial
     statements unless a refund of, or reduction in, contributions is likely.
     Under U.S. GAAP, a negative pension cost may arise where a significant
     unrecognised net asset or gain exists at the time of implementation. This
     is required to be amortised on a straight-line basis over the average
     remaining service period of employees.

The reconciling difference for net (loss)/income between Irish and U.S. GAAP was
$2.2 million, $1.1 million and $0.9 million for 2002, 2001 and 2000,
respectively. The reconciling difference to shareholders' equity, includes
prepaid pension assets of $7.9 million, offset by $9.8 million in 2002 in
respect of the shortfall between the unfunded accumulated benefit obligation and
the unrecognised prior service cost and the prepaid benefit cost. Under Irish
GAAP, Elan has accounted for pensions in accordance with SSAP 24. A new
accounting standard, FRS 17, was issued in 2001 dealing with retirement
benefits. This is not mandatory until 2005. Prior to this, phased transitional
disclosures are required, which are detailed in Note 28 to the Consolidated
Financial Statements. The standard introduces changes to the accounting for
defined benefit schemes, the basic requirements of which are: pension scheme
assets are measured using fair values; pension scheme liabilities are measured
using a projected unit method and discounted at the current rate of return on a
high quality corporate bond; and full actuarial valuations should be obtained at
intervals not exceeding three years. There is also a requirement that these
valuations should be updated at each balance sheet date.


K    FINANCIAL FIXED ASSETS

Under Irish GAAP, non-current financial fixed assets are recorded at cost less
provision for permanent impairment in value. Under U.S. GAAP, in accordance with
SFAS No. 115 certain financial fixed assets were classified as available for
sale and reported at fair value and the unrealised gains and losses were
excluded from earnings and reported as a separate component of comprehensive
income (net of tax). The difference in shareholders' equity between Irish and
U.S. GAAP, arising from differences in the accounting treatment for financial
fixed assets, was $21.0 million at 31 December 2002 (2001: $41.6 million).


L    CONSOLIDATED CASH FLOW DATA

In accordance with Irish GAAP, Elan complies with FRS No. 1, "Cash Flow
Statements" ("FRS 1"). Its objective and principles are similar to those set out
in SFAS No. 95, "Statement of Cash Flows" ("SFAS No. 95"). The principal
difference between the standards is in respect of classification. Under FRS 1,
the Group has presented its cash flows for (a) operating activities; (b) returns
on investments and servicing of


- --------------------------------------------------------------------------------
154


- --------------------------------------------------------------------------------

finance; (c) taxation; (d) capital expenditure and financial investment; (e)
acquisitions and disposals; and (f) financing activities. SFAS No. 95 requires
only three categories of cash flow activity, (a) operating; (b) investing; and
(c) financing.

Cash flows arising from taxation and returns on investments and servicing of
finance under FRS 1 are included as operating activities under SFAS No. 95. In
addition, under FRS 1, cash and liquid resources include short term borrowings
repayable on demand. SFAS No. 95 requires movements in such borrowings to be
included in financing activities.

For the purposes of cash flows under U.S. GAAP, the Group considers all highly
liquid deposits with an original maturity of three months or less to be cash
equivalents. Under Irish GAAP, cash represents cash held at bank available on
demand offset by bank overdrafts. Liquid resources comprise bank fixed deposits
with maturities of greater than one day.

The reconciling difference between Irish GAAP cash and liquid resources and U.S.
GAAP cash and cash equivalents is included on page 164. Cash balances held by
EPIL (prior to March 2001) and EPIL II have been included in cash and liquid
resources under Irish GAAP as these entities have been consolidated under Irish
GAAP. As the entities have not been consolidated subsidiaries under U.S. GAAP,
their cash balances have not been included in cash and cash equivalents under
U.S. GAAP. In 2002, under U.S. GAAP, there were marketable investments of $22.7
million (2001: $134.1 million) whose maturity was greater than three months.
These were treated as liquid resources under Irish GAAP as they were readily
convertible into cash and were traded in an active market.


M    NEW ACCOUNTING STANDARDS (U.S. GAAP)

Adopted

In July 2001, the FASB issued SFAS No. 142, which revises the accounting for
purchased goodwill and other intangible assets. SFAS No. 142 is effective for
fiscal years beginning after 15 December 2001, with earlier adoption permitted.
Elan adopted SFAS No. 142 effective 1 January 2002. Under SFAS No. 142,
purchased goodwill and intangible assets with indefinite lives are no longer
amortised, but instead tested for impairment at least annually. Accordingly,
Elan has ceased amortisation of all goodwill as of 1 January 2002. The goodwill
amortisation charge, under U.S. GAAP, was $30.0 million and $20.0 million for
2001 and 2000, respectively. Under U.S. GAAP Elan does not have any intangible
assets, other than goodwill, with indefinite lives. Existing intangible assets
with finite lives, primarily patents and trademarks, continue to be amortised on
a straight-line basis over their useful lives. Elan has not estimated aggregate
amortisation expense for each of the five succeeding fiscal years due to its
inability to make a meaningful estimate as a result of the continuing
implementation of the Group's recovery plan.

SFAS No. 142 requires an annual two step impairment test for goodwill. The first
step is to identify reporting units within the Group and compare the carrying
amount of the reporting unit's assets, including goodwill, to the fair value of
the reporting unit. A second step is required if the carrying amount of the
reporting unit's assets, including goodwill, exceeds its fair value. The second
step requires that the fair value of the reporting unit be allocated to each
asset and liability based on the fair value of the individual assets or
liabilities, with any unallocated fair value being implied goodwill. The
impairment loss is the amount by which the carrying value of goodwill exceeds
the implied goodwill.

Upon adoption of SFAS No. 142 on 1 January 2002, Elan performed its initial
amendment of goodwill and determined that no impairment charge arose. On 31 July
2002, Elan announced a recovery plan to restructure its businesses, assets and
balance sheet. Elan reorganised into two primary business units: Core Elan and
Elan Enterprises. SFAS No. 142 also requires goodwill impairment tests to be
performed between annual tests in certain circumstances. Elan tested goodwill
for impairment at 30 September 2002 and determined that an impairment charge to
goodwill of $54.7 million had arisen. Elan performed a goodwill impairment test
at 31 December 2002 and determined that an impairment charge to goodwill of
$26.8 million had arisen. These charges arose due to the impact of the recovery
plan, and related to Elan Enterprises. The fair values of Elan's reporting
units, as required under the first stage of impairment testing in SFAS No. 142,
were calculated using present value techniques. This involved discounting the
projected future cash flows of the reporting units at appropriate risk-adjusted
discount rates. The U.S. GAAP goodwill balance was $324.8 million at 31 December
2002 (2001: $506.6 million).

In August 2001, the FASB issued SFAS No. 144. SFAS No. 144 addresses financial
accounting and reporting for the impairment or disposal of long-lived assets.
This statement supersedes SFAS No. 121. This statement is effective for
financial statements issued for fiscal years beginning after 15 December 2001.
Elan adopted SFAS No. 144 effective 1 January 2002.

Under SFAS No. 144, long-lived assets to be held and used shall be reviewed for
impairment using a two step approach. The first step is to assess whether the
carrying amount of a long-lived asset is recoverable from its undiscounted cash
flows. If the undiscounted cash flows of the long-lived asset are less than its
carrying value then the second step is required. The second step requires the
recognition of an impairment loss, measured as the difference between the
carrying amount and fair value of the asset. For long-lived assets to be
disposed of by sale, the statement requires that the long-lived asset be
classified as held for sale at the lower of its carrying amount or fair value
less cost to sell and to cease depreciation (amortisation). Therefore,
discontinued operations are no longer measured on a net realisable value basis,
and future operating losses are no longer recognised before they occur.


To be adopted

In June 2001, the FASB issued SFAS No. 143, "Accounting for Asset Retirement
Obligations" ("SFAS No. 143"). SFAS No. 143 addresses financial accounting and
reporting for obligations associated with the retirement of long-lived tangible
assets and the associated asset retirement costs. The Statement requires that
the fair value of liabilities for asset retirement obligations be recorded in
the period in which they are incurred if a reasonable estimate of fair value can
be made. The associated asset retirement costs are capitalised as part of the
carrying amount of the long-lived asset. This statement is effective for
financial statements issued for fiscal years beginning after 15 June 2002. The
Group is continuing to evaluate the impact of SFAS No. 143 on its financial
statements.

In April 2002, the FASB issued SFAS No. 145, "Rescission of FASB Statements No.
4, 44 and 64, Amendment of FASB Statement No. 13, and Technical Corrections"
("SFAS No. 145"). SFAS No. 145 provides for the rescission of several previously
issued accounting standards, new accounting guidance for the accounting for
certain lease modifications and various technical corrections that are not
substantive in nature to existing pronouncements. SFAS No. 145 will be adopted
beginning 1 January 2003, except for the provisions relating to the amendment of
SFAS No. 13, which was adopted for transactions occurring subsequent to 15 May
2002. Elan does not expect that SFAS No. 145 will have a material impact on the
financial statements.

In June 2002, the FASB issued SFAS No. 146 "Accounting for the Costs Associated
with Exit or Disposal Activities" ("SFAS No. 146"), which nullifies EITF Issue
94-3, Liability Recognition for Certain Employee Termination Benefits and Other
Costs to Exit an Activity (Including Certain Costs Incurred in a Restructuring).
SFAS No. 146 requires that a liability for costs associated with exit or
disposal activities first be recognised when the liability is irrevocably
incurred rather than at the date of management's commitment to an exit or
disposal plan. In addition, SFAS No. 146 stipulates that the liability be
measured at fair value and adjusted for changes in estimated cash flows. The
provisions of the new standard are effective prospectively for exit or disposal
activities initiated after 31 December 2002. Since SFAS No. 146 applies to
future activities that may not yet be envisaged, the impact of the application
of SFAS No. 146 cannot be determined in advance.

In November 2002, the FASB issued FASB Interpretation No. 45 "Guarantor's
Accounting and Disclosure Requirements for Guarantees, including Indirect
Guarantees of Indebtedness of Others" ("FIN 45"). This interpretation addresses
the disclosure to be made by a guarantor in its financial statements about its
obligation under guarantees. FIN 45 also requires the guarantor to recognise a
liability for the non-contingent component of the guarantee, that is the
obligation to stand ready to perform in the event that specified triggering
events or conditions occur. The initial measurement of this liability is the
fair value of the guarantee at inception. The disclosure requirements in this
Interpretation are effective for financial statements of interim and annual
periods ending after 15 December 2002. The recognition and measurement
provisions are applicable on a prospective basis to guarantees issued or
modified after 31 December 2002, irrespective of the guarantor's fiscal
year-end. The Group has adopted the disclosure requirements of FIN 45 and will
apply the recognition and measurement provisions for all guarantees entered into
or modified after 31 December 2002. In accordance with FIN 45, the following
table provides the undiscounted amount of maximum potential future payments for
each major group of guarantee:

Under its strategic alliance with Wyeth, Elan assumed responsibility for the
U.S. marketing of Sonata and had the option to acquire the U.S. product rights
to Sonata. Elan Corporation, plc had guaranteed all of its subsidiary's
commitments under the agreements with Wyeth. At 31 December 2002, the estimated
potential payment due in connection with Sonata was $294.9 million, of which
$63.7 million was recorded as a liability under U.S. GAAP. The remaining balance
of $231.2 million represented the undiscounted amount of potential future
payments in respect of Elan's parent company guarantee under the Wyeth
agreements. As part of the disposal of Elan's primary care franchise, the
product payments related to Sonata were assumed by King.

In September 2001, Elan acquired the Pain Portfolio from Roxane. Elan
Corporation, plc has guaranteed all of its subsidiary's commitments under the
agreements with Roxane. At 31 December 2002, the potential payment due in
connection with the Pain Portfolio was $90.0 million, of which $77.4 million was
recorded as a liability under U.S. GAAP. The remaining balance of $12.6 million
represents the undiscounted amount of potential future payments in respect of
Elan's parent company guarantee under the Roxane agreements.

For additional information regarding Elan's future payments and potential future
payments relating to product acquisitions and alliances, please refer to Note 17
to the Consolidated Financial Statements.

Elan Corporation, plc has provided subordinated guarantees to the holders of the
LYONs for the repayment of the loan notes. In the event that Elan Finance does
not meet its obligations to pay amounts due to the noteholders, the noteholders
may call upon the Elan Corporation, plc guarantees. For additional information
regarding the LYONs, please refer to Note 16 to the Consolidated Financial
Statements.

Elan Corporation, plc has provided subordinated guarantees to the holders of the
EPIL II Notes and the EPIL III Notes for the repayment of the loan notes and the
payment of any unpaid interest. In the event that EPIL II or EPIL III do not
meet their obligations to pay amounts due to the noteholders, the noteholders
may call upon the Elan Corporation, plc guarantees.

Elan Corporation, plc has provided guarantees to the holders of the 7.25% Senior
Notes for the repayment of the loan notes and the payment of any unpaid
interest. In the event that Athena Finance does not meet its obligations to pay
amounts due to the noteholders, the noteholders may call upon the Elan
Corporation, plc guarantees.

In December 2002, the FASB issued SFAS No. 148, "Accounting for Stock Based
Compensation--Transition and Disclosure--an amendment of SFAS Statement No. 123"
("SFAS No. 148"). SFAS No. 148 provides alternative methods of transition for a

change to the fair value based method of accounting for stock-based employee
compensation. In addition, this statement amends the disclosure requirements of
SFAS No. 123 to require prominent disclosures in both annual and interim
financial statements about the method of accounting for stock-based employee
compensation and the effect of the method used on reported results. The
transition provisions of SFAS No. 148 are effective for fiscal years ending
after 15 December 2002. The enhanced disclosure requirements are effective for
periods beginning after 15 December 2002. The Company has not yet decided if it
will adopt either of the transition method alternatives of SFAS No. 148.

In January 2003, the FASB issued FASB Interpretation No. 46, "Consolidation of
Variable Interest Entities" ("FIN 46"), which interprets Accounting Research
Bulletin No. 51, "Consolidated Financial Statements" ("ARB No. 51"). FIN 46
clarifies the application of ARB No. 51 with respect to the consolidation of
certain entities (variable interest entities--"VIEs") to which the usual
condition for consolidation described in ARB No. 51 does not apply because the
controlling financial interest in VIEs may be achieved through arrangements that
do not involve voting interests. In addition, FIN 46 requires the primary
beneficiary of VIEs and the holder of a significant variable interest in VIEs to
disclose certain information relating to their involvement with the VIEs. The
provisions of FIN 46 apply immediately to VIEs created after 31 January 2003,
and to VIEs in which an enterprise obtains an interest after that date. FIN 46
applies in the first fiscal year beginning after 15 June 2003, to VIEs in which
an enterprise holds a variable interest that it acquired before 1 February 2003.
The Group is currently evaluating the impact of adopting FIN 46 on its financial
statements. In particular, the Group is considering whether Amarin or any of the
Group's business ventures would be variable interest entities. For information
on the business ventures and on the Group's relationship with Amarin, please
refer to Notes 26 and 27, respectively, to the Consolidated Financial
Statements.

In April 2003, the FASB issued SFAS Statement No. 149, "Amendment of Statement
133 on Derivative Instruments and Hedging Activities" ("SFAS No. 149"), which
amends SFAS Statement No. 133, to address (1) decisions reached by the
Derivatives Implementation Group, (2) developments in other FASB projects that
address financial instruments, and (3) implementation issues related to the
definition of a derivative. SFAS No. 149 has multiple effective date provisions
depending on the nature of the amendment to SFAS No. 133. The Company is
currently evaluating the impact of adopting SFAS No. 149 on its financial
statements.

In May 2003, the FASB issued SFAS No. 150, "Accounting for Certain Financial
Instruments with Characteristics of both Liabilities and Equity". SFAS No. 150
establishes standards for how an issuer classifies and measures certain
financial instruments with characteristics of both liabilities and equity. It
requires that an issuer classify a financial instrument that is within its scope
as a liability (or an asset in some circumstances). Many of those instruments
were previously classified as equity. SFAS No. 150 is effective for financial
instruments entered into or modified after 31 May 2003, and otherwise is
effective at the beginning of the first interim period beginning after 15 June
2003, except for mandatorily redeemable financial instruments of non-public
entities. It is to be implemented by reporting the cumulative effect of a change
in an accounting principle for financial instruments created before the issuance
date of SFAS No. 150 and still existing at the beginning of the interim period
of adoption. Restatement is not permitted. For non-public entities, mandatorily
redeemable financial instruments are subject to the provisions of SFAS No. 150
for the first fiscal period beginning after 15 December 2003. The Company is
currently evaluating the impact of adopting SFAS No. 150 on its financial
statements.

U.S. GAAP CONDENSED FINANCIAL DATA

Due to the differences between Irish and U.S. GAAP, and in particular the
accounting of the merger of Dura and Elan as a pooling of interests under U.S.
GAAP, the following condensed financial data has been prepared for the benefit
of U.S. investors on pages 161 to 163.

Under Irish GAAP, exceptional items are those items that in management's
judgement are material items which derive from events or transactions that fall
within the ordinary activities of the Group and which individually or, if of a
similar type, in aggregate, need to be disclosed by virtue of their size or
incidence. Under U.S. GAAP, exceptional items would be included in operating
income, unless they relate to discontinued operations. Cash flows relating to
product rationalisations are included in operating cash flows.

The weighted average assumptions used in the calculation of the pension cost for
2002 were a discount rate of 5.5% (2001: 6%; 2000: 6.25%), an expected return on
plan assets of 8% (2001: 9%; 2000: 9%) and a 3.5% (2001: 4%; 2000: 4.25%) rate
of compensation increase.

Elan recognised a $9.8 million charge to Other Comprehensive Income in 2002 in
respect of the shortfall between the unfunded accumulated benefit obligation
less the unrecognised prior service cost and the prepaid benefit cost.

In addition, Elan operates a number of defined contribution pension plans,
primarily for employees outside of Ireland. The costs of these plans are charged
to the income statement in the period they are incurred. The pension cost for
these plans was $8.8 million, $9.9 million and $7.3 million for 2002, 2001 and
2000, respectively.

COMPENSATION COST (U.S. GAAP)

Elan grants options to employees under the Group's stock option plans. These
options are granted at fixed exercise prices equal to the market value on the
date of grant.

The Company applies APB 25 in accounting for its stock option plans and,
accordingly under U.S. GAAP, no compensation expense is recognised when stock
options are initially granted to employees as the exercise price is equal to the
market price on the date of grant. If the Company determined compensation cost
based on the fair value at the grant date for its stock options under SFAS No.
123, the effect on net income under U.S. GAAP is as shown below.

Under U.S. GAAP, Elan applies SFAS No. 109 which requires the asset and
liability method of accounting for income taxes. Under this method, deferred tax
assets and liabilities are recognised for the future tax consequences
attributable to differences between the financial statement carrying amounts of
existing assets and liabilities and their respective tax bases and operating
loss and tax credit carryforwards. Deferred tax assets and liabilities are
measured using enacted tax rates expected to apply to taxable income in the
years in which those temporary differences are expected to be recovered or
settled. The effect on deferred tax assets and liabilities of a change in tax
rates is recognised in income in the period that includes the enactment date. A
valuation allowance is established in respect of those deferred tax assets where
it is more likely than not that some portion will not be realised in the future.
The valuation allowance recorded against the deferred tax assets at 31 December
2002 was $431.6 million. The net change in the valuation allowance for 2002 was
an increase of $29.6 million. $136.6 million of the valuation allowance at 31
December 2002, included primarily under net operating losses, is expected to be
applied directly to contributed capital under U.S. GAAP when deferred tax assets
associated with certain stock option exercises are recognised.

At 31 December 2002 and 31 December 2001, certain U.S. subsidiaries had net
operating loss carryovers for federal income tax purposes of $462.6 million and
$659.4 million, respectively, and for state income tax purposes of $153.7
million and $167.5 million, respectively. Both the federal and state net
operating losses will expire from 2004 to 2022 to the extent they are not
utilised. In addition, at 31 December 2002 and 31 December 2001, certain U.S.
subsidiaries had credit carryovers for federal and state income tax purposes of
$78.4 million and $74.4 million, respectively, which will expire from 2003 to
2021 to the extent they are not utilised, except for certain sale credits which
can be carried to subsequent tax years indefinitely. The Company has had
"changes in ownership" as described in the U.S. Internal Revenue Code Section
382. Consequently, utilisation of federal and state net operating losses and
credits are subject to certain annual limitations.

At 31 December 2002 certain non-U.S. subsidiaries of Elan had net operating loss
carryovers for income tax purposes of $706.4 million. These combined loss
carryovers have arisen in a number of different tax jurisdictions and as such
are subject to various local restrictions. The loss carryovers are also subject
to varying expiration dates beginning in 2003, with certain losses carrying
forward indefinitely.

No taxes have been provided for the unremitted and untaxed earnings of the
Group's overseas subsidiaries as these are, in the main, considered permanently
employed in the business of these companies. Cumulative unremitted earnings of
overseas subsidiaries and related undertakings totalled $646.0 million at 31
December 2002. Unremitted earnings may be liable to overseas taxes and/or Irish
taxation if they were to be distributed as dividends.

The U.S. Internal Revenue Service has completed an audit of Dura and its
subsidiaries for the 1997-2000 tax years, which pre-date the acquisition of Dura
by the Company. As adequate amounts for tax and related interest had been
provided, no additional tax was charged as a result of this audit.

Elan has not paid cash dividends on its Ordinary Shares in the past. The
declaration of any cash dividends will be at the recommendation of Elan's board
of directors. The recommendations of Elan's board of directors will depend upon
the earnings, capital requirements and financial condition of Elan and other
relevant factors. Although Elan does not anticipate that it will pay any cash
dividends on its Ordinary Shares in the foreseeable future, Elan expects that
its board of directors will review Elan's dividend policy on a regular basis.
Dividends may be paid on Elan's Executive Shares and `B' Executive Shares at a
time when no dividends are being paid on the Ordinary Shares. For additional
information regarding the Executive Shares and `B' Executive Shares, please
refer to Note 18 to the Consolidated Financial Statements.

A total of 350,758,430 Ordinary Shares of Elan were issued and outstanding at 25
August 2003, of which 4,050 Ordinary Shares were held by holders of record in
the United States, excluding shares held in the form of ADRs. 311,441,128
Ordinary Shares were represented by Elan ADSs, evidenced by ADRs, issued by The
Bank of New York, as depositary, pursuant to a deposit agreement. At 25 August
2003, the number of holders of record of Ordinary Shares was 7,742, which
includes 10 holders of record in the United States, and the number of registered
holders of ADRs in the United States was 4,902. Because certain of these
Ordinary Shares and ADRs were held by brokers or other nominees, the number of
holders of record or registered holders in the United States and Ireland is not
representative of the number of beneficial holders or of the residence of
beneficial holders.

Elan ADSs, were traded on the NYSE under the symbol "ELNWSA" ("A-Series

EXCHANGE CONTROLS AND OTHER LIMITATIONS AFFECTING SECURITY HOLDERS

Irish exchange control regulations ceased to apply from and after 31 December
1992. Except as indicated below, there are no restrictions on non-residents of
Ireland dealing in domestic securities, which includes shares or depositary
receipts of Irish companies such as Elan. Except as indicated below, dividends
and redemption proceeds also continue to be freely transferable to non-resident
holders of such securities. The Financial Transfers Act, 1992 gives power to the
Minister for Finance of Ireland to make provision for the restriction of
financial transfers between Ireland and other countries and persons. Financial
transfers are broadly defined and include all transfers which would be movements
of capital or payments within the meaning of the treaties governing the member
states of the EU. The acquisition or disposal of ADSs or ADRs representing
shares issued by an Irish incorporated company and associated payments falls
within this definition. In addition, dividends or payments on redemption or
purchase of shares and payments on a liquidation of an Irish incorporated
company would fall within this definition. At present the Financial Transfers
Act, 1992 prohibits financial transfers involving Iraq, the Federal Republic of
Yugoslavia, the Republic of Serbia, Zimbabwe, the Taliban of Afghanistan, Osama
bin Laden and Al-Qaeda, and countries that harbour certain terrorist groups,
without the prior permission of the Central Bank of Ireland.

Any transfer of, or payment in respect of, an ADS involving the government of
any country which is currently the subject of United Nations sanctions, any
person or body controlled by any of the foregoing, or by any person acting on
behalf of the foregoing, may be subject to restrictions pursuant to such
sanctions as implemented into Irish law. The following countries and persons are
currently the subject of such sanctions: Federal Republic of Yugoslavia,
Republic of Serbia, Iraq, Liberia, Burma/Myanmar, Zimbabwe, the Taliban of
Afghanistan, Osama bin Laden and Al-Qaeda. Elan does not anticipate that orders
under the Financial Transfers Act, 1992, or United Nations sanctions implemented
into Irish law will have a material effect on its business.


IRISH TAXATION

The following is a general description of Irish taxation inclusive of certain
Irish tax consequences to U.S. Holders (as defined below) of the purchase,
ownership and disposition of Elan ADSs or Ordinary Shares. As used herein,
references to the Ordinary Shares include Elan ADSs representing such Ordinary
Shares, unless the tax treatment of the Elan ADSs and Ordinary Shares has been
specifically differentiated. This description is for general information
purposes only and does not purport to be a comprehensive description of all the
Irish tax considerations that may be relevant in a U.S. Holder's decision to
purchase, hold or dispose of Ordinary Shares. It is based on the various Irish
Taxation Acts, all as in effect on 31 March 2003 and all of which are subject to
change (possibly on a retroactive basis). The Irish tax treatment of a U.S.
Holder of Ordinary Shares may vary depending upon such holder's particular
situation, and holders or prospective purchasers of Ordinary Shares are advised
to consult their own tax advisors as to the Irish or other tax consequences of
the purchase, ownership and disposition of Ordinary Shares.

For the purposes of this tax description, a "U.S. Holder" is a holder of
Ordinary Shares that is: (i) a citizen or resident of the United States; (ii) a
corporation or partnership created or organised in or under the laws of the
United States or of any political subdivision thereof; (iii) an estate, the
income of which is subject to U.S. federal income taxation regardless of its
source; or (iv) a trust, if a U.S. court is able to exercise primary supervision
over the administration of such trust and one or more U.S. persons have the
authority to control all substantial decisions of such trust.

TAXATION OF CORPORATE INCOME

Elan is a public limited company incorporated, and resident for tax purposes, in
Ireland. Under current Irish legislation, a company is regarded as resident for
tax purposes in Ireland if it is centrally managed and controlled in Ireland,
or, in certain circumstances, if it is incorporated in Ireland. The Taxes
Consolidation Act, 1997, provides that a company which is resident in Ireland
and which is not resident elsewhere shall be entitled to have any income from a
qualifying patent disregarded for taxation purposes. The legislation does not
provide a termination date for this relief. A qualifying patent means a patent
in relation to which the research, planning, processing, experimenting, testing,
devising, designing, developing or similar activities leading to the invention
which is the subject of the patent were carried out in Ireland. Income from a
qualifying patent means any royalty or other sum paid in respect of the use of
the invention to which the qualifying patent relates, including any sum paid for
the grant of a licence to exercise rights under such patent, where that royalty
or other sum is paid, for the purpose of activities which would be regarded
under Irish law as the manufacture of goods (to the extent that the payment does
not exceed an arms-length rate), or by a person who is not connected with Elan.
Accordingly, Elan's income from such qualifying patents is disregarded for
taxation purposes in Ireland. Any Irish manufacturing income of Elan and its
subsidiaries is taxable at the rate of 10% in Ireland until 31 December 2010.
Income arising from qualifying activities in Elan's Shannon-certified subsidiary
is taxable at the rate of 10% in Ireland until 31 December 2005. From 1 January
2006, it is anticipated, based on Irish legislation currently enacted, that such
income will be taxable at a rate of 12.5%. Any trading income of Elan which does
not qualify for the patent exemption or the 10% rate of tax is taxable at the
Irish corporation tax rate of 16% in respect of trading income for the year 2002
and at a rate of 12.5% in respect of trading income for the years 2003 et seq.
Non-trading income is taxable at 25%.

TAXATION OF CAPITAL GAINS AND DIVIDENDS

A person who is neither resident nor ordinarily resident in Ireland and who does
not carry on a trade in Ireland through a branch or agency will not be subject
to Irish capital gains tax on the disposal of Ordinary Shares. Unless exempted,
all dividends paid by Elan other than dividends paid out of exempt patent
income, will be subject to Irish withholding tax at the standard rate of income
tax in force at the time the dividend is paid, currently 20%. An individual
shareholder resident in a country with which Ireland has a double tax treaty,
which includes the United States, or in a member state of the EU, other than
Ireland (together, a "Relevant Territory"), will be exempt from withholding tax
provided he or she makes the requisite declaration.

Corporate shareholders who: (i) are ultimately controlled by residents of a
Relevant Territory; (ii) are resident in a Relevant Territory and are not
controlled by Irish residents; (iii) have the principal class of their shares,
or of a 75% parent, traded on a stock exchange in a Relevant Territory; or (iv)
are wholly owned by two or more companies, each of whose principal class of
shares is substantially and regularly traded on one or more recognised stock
exchanges in a Relevant Territory or Territories, will be exempt from
withholding tax on the production of the appropriate certificates and
declarations.

Holders of Elan ADSs will be exempt from withholding tax if they are
beneficially entitled to the dividend and their address on the register of
depositary shares maintained by the depositary is in the United States, provided
that the depositary has been authorised by the Irish Revenue Commissioners as a
qualifying intermediary and provided the appropriate declaration is made by the
holders of the ADSs. Where such withholding is made, it will satisfy the
liability to Irish tax of the shareholder except in certain circumstances where
an individual shareholder may have an additional liability. A charge to Irish
social security taxes and other levies can arise for individuals. However, under
the Social Welfare Agreement between Ireland and the United States, an
individual who is liable for U.S. social security contributions can normally
claim exemption from these taxes and levies.

IRISH CAPITAL ACQUISITIONS TAX

A gift or inheritance of Ordinary Shares will be and, in the case of Elan
warrants or ADWSs representing such Elan warrants, may be, within the charge to
Irish capital acquisitions tax, notwithstanding that the person from whom the
gift or inheritance is received is domiciled or resident outside Ireland.
Capital acquisitions tax is charged at the rate of 20% above a tax free
threshold. This tax free threshold is determined by the relationship between the
donor and the successor or donee. It is also affected by the amount of the
current benefit and previous benefits taken since 5 December 1991 from persons
within the same capital acquisitions tax relationship category. Gifts and
inheritances between spouses are not subject to capital acquisitions tax.

The Estate Tax Convention between Ireland and the United States generally
provides for Irish capital acquisitions tax paid on inheritances in Ireland to
be credited against tax payable in the United States and for tax paid in the
United States to be credited against tax payable in Ireland, based on priority
rules set forth in the Estate Tax Convention, in a case where Elan warrants,
Elan ADWSs, Elan ADSs or Ordinary Shares are subject to both Irish capital
acquisitions tax with respect to inheritance and U.S. Federal estate tax. The
Estate Tax Convention does not apply to Irish capital acquisitions tax paid on
gifts.

IRISH STAMP DUTY

Under current Irish law, no stamp duty, currently at the rate and on the amount
referred to below, will be payable by U.S. Holders on the issue of Elan ADSs,
Ordinary Shares or Elan ADWSs. Under current Irish law, no stamp duty will be
payable on the acquisition of Elan ADWSs or Elan ADSs by persons purchasing
such Elan ADWSs or Elan ADSs or any subsequent transfer of an Elan ADWS or Elan
ADS. A transfer of Ordinary Shares, whether on sale, in contemplation of a sale
or by way of gift will attract duty at the rate of 1% on the consideration
given or, where the purchase price is inadequate or unascertainable, on the
market value of the shares. Similarly, any such transfer of a warrant may
attract duty at the rate of 1%. Transfers of Ordinary Shares which are not
liable to duty at the rate of 1% are exempt unless the transfer is by way of
security, in which event there is a potential maximum charge of Euro 630. The
person accountable for payment of stamp duty is the transferee or, in the case
of a transfer by way of gift or for a consideration less than the market value,
all parties to the transfer. Stamp duty is normally payable within 30 days
after the date of execution of the transfer. Late or inadequate payment of
stamp duty will result in a liability to pay interest penalties and fines.

RISK FACTORS

You should carefully consider all of the information set forth in this Annual
Report and Form 20-F, including the following risk factors, before investing in
our securities. The risks described below are not the only ones we face.
Additional risks not currently known to us or that we presently deem immaterial
may also impair our business operations. Our business, financial condition,
results of operations and liquidity could be materially adversely affected by
any of these risks. This Annual Report and Form 20-F also contains
forward-looking statements that involve risks and uncertainties. Any
forward-looking statements are not guarantees of future performance and actual
results; developments and business decisions may differ materially from those
contemplated by such forward-looking statements as a result of certain risks and
uncertainties, including those described below. For additional information,
please refer to "Cautionary Factors That May Affect Future Results ".

WE AND CERTAIN OF OUR CURRENT AND FORMER OFFICERS AND DIRECTORS HAVE BEEN NAMED
AS DEFENDANTS IN A PUTATIVE CLASS ACTION AND TWO LAWSUITS CLAIMING TO BE BROUGHT
DERIVATIVELY ON OUR BEHALF, AND WE ARE THE SUBJECT OF AN SEC INVESTIGATION; AN
ADVERSE OUTCOME OR RESOLUTION IN THESE PROCEEDINGS OR THE INVESTIGATION COULD
RESULT IN SUBSTANTIAL PAYMENTS BY US AND COULD HAVE A MATERIAL ADVERSE EFFECT ON
OUR BUSINESS, FINANCIAL CONDITION, RESULTS OF OPERATIONS AND LIQUIDITY.

Elan and certain of its current and former officers and directors are named as
defendants in a putative class action in the U.S. District Court for the
Southern District of New York, which consolidated several class actions that
were filed in early 2002. The amended and consolidated complaint filed on 24
January 2003 in the action (the "Complaint") alleges claims under the U.S.
federal securities laws, including that our financial statements were not in
accordance with generally accepted accounting principles and that the defendants
disseminated materially false and misleading information concerning our business
and financial results, our investments in certain business ventures and business
venture parents, and the licence fees and research revenues received by us from
the business ventures; the accounting for proceeds from our sale of certain
product lines and disclosure concerning those sales; the accounting for certain
risk-sharing arrangements that we entered into and disclosure concerning those
arrangements; the accounting for certain qualifying special purpose entities and
disclosure concerning those entities; the disclosure of compensation of certain
of our officers; and certain alleged related party transactions. The Complaint
seeks compensatory damages and other relief that the court may deem proper. We
are also a nominal defendant in two derivative actions filed against certain of
our former and current directors and certain of our former and current officers
on or about 14 March 2002 and 20 March 2002 in the Superior Court of the State
of California, County of San Diego. The two actions have been consolidated. The
complaint contains allegations similar to those set forth in the foregoing
actions, but alleges, among other things, that the defendant officers and
directors breached their duties to us by causing us to undertake the actions
alleged in the Complaint. Among other relief, the action seeks damages against
the defendant officers and directors on our behalf. Finally, we are the subject
of an ongoing investigation by the SEC's Division of Enforcement commenced on or
about 12 February 2002, which we believe relates primarily to the issues raised
in the actions described above. We are unable to predict or determine the
outcome of the actions or the investigation or reasonably estimate the amount or
range of loss, if any, with respect to the resolution of the actions or the
investigation (except that, as discussed in Note 25 to the Consolidated
Financial Statements, an agreement to settle the two derivative actions has been
reached that remains subject to court approval). In addition, the timing and
final resolution of the actions and the investigation is uncertain. The Company
continues to believe that it has prepared its financial statements in accordance
with applicable GAAP, (subject to the restatement of EPIL III under U.S. GAAP,
described on pages 142 to 147). The findings and outcome of the investigation
may adversely affect the course of the actions. The possible outcome or
resolution of these proceedings could require us to make substantial payments.
Any amendment or restatement of our previously filed financial statements, any
substantial payment required to be made by us in connection with the resolution
of the investigation and any adverse determination in the actions could have a
material adverse effect on our business, financial condition, results of
operations and liquidity. Further, we are unable to predict or determine the
impact, if any, that the 2001 restatement may have on the outcome of the
shareholder litigation.

We are generally obliged to indemnify our current and former officers and
directors who are also named as defendants in some or all of these matters to
the extent permitted by Irish law.

Please refer to Note 25 to the Consolidated Financial Statements for further
information on the SEC investigation and these actions.

RISK FACTORS
- --------------------------------------------------------------------------------

WE HAVE SUBSTANTIAL FUTURE CASH NEEDS AND POTENTIAL CASH NEEDS AND WE CANNOT
ASSURE YOU THAT WE WILL BE SUCCESSFUL IN GENERATING OR OTHERWISE OBTAINING THE
FUNDS NECESSARY TO MEET THOSE NEEDS.

At 31 December 2002, we had approximately $2,742 million of contractual future
cash payments and approximately $382 million of potential future cash payments,
excluding expected capital expenditures on plant and equipment, lease payments
and future investments in financial assets such as investments in business
ventures. At such date, we had cash and liquid resources of approximately $1,087
million. We estimate that we have sufficient cash, liquid resources and
realisable assets and investments to meet our near-term liquidity requirements.
In making this estimate, we have not assumed any material payments in connection
with our pending litigations during that period. Any material adverse legal
judgements, fines, penalties or settlements arising from our pending litigations
or investigations could require us to obtain additional funds. Although we
expect to incur an operating loss for fiscal 2003, in making our liquidity
estimates, we have also assumed a certain level of operating performance. Our
future operating performance will be affected by general economic, financial,
competitive, legislative, regulatory and business conditions and other factors,
many of which are beyond our control. If our future operating performance is
less than anticipated, including as a result of our failure to timely obtain
marketing approval for products under development, we could be required to
obtain additional funds. As described below, certain events, including our
inability to incur additional indebtedness under the restrictive covenants
contained in our existing debt instruments, have materially adversely affected
our financial flexibility, including our ability to access external sources of
capital to finance our business. If our estimates are incorrect and we are
required to obtain additional funds, we cannot assure you that we would be able
to obtain those funds on commercially reasonable terms, or at all, which would
have a material adverse effect on our business, financial condition, results of
operations and liquidity.

In July 2002, we announced a recovery plan designed to enable us to meet our
financial obligations. We cannot assure you that the recovery plan will be
successful in generating the funding expected or that we will otherwise be
successful in generating the funds necessary to enable us to meet our
longer-term liquidity requirements.

CERTAIN EVENTS, INCLUDING OUR INABILITY TO INCUR ADDITIONAL INDEBTEDNESS UNDER
THE RESTRICTIVE COVENANTS CONTAINED IN OUR EXISTING DEBT INSTRUMENTS, HAVE
MATERIALLY ADVERSELY AFFECTED OUR FINANCIAL FLEXIBILITY, INCLUDING OUR ABILITY
TO ACCESS EXTERNAL SOURCES OF CAPITAL TO FINANCE OUR BUSINESS, AND MAY
MATERIALLY ADVERSELY AFFECT OUR ABILITY TO OBTAIN SUFFICIENT CAPITAL TO MEET OUR
LIQUIDITY REQUIREMENTS.

The agreements governing certain of our outstanding indebtedness contain
covenants restricting our ability and the ability of our subsidiaries to incur
additional indebtedness (including intercompany indebtedness). We do not
currently have the ability to incur any additional indebtedness under these
covenants. Our inability to incur additional indebtedness (including
intercompany indebtedness), together with certain other events, such as the
class action and derivative litigations, and the SEC investigation, described
above, the decline in price of our shares and the downgrades of our debt
ratings, have materially adversely affected our financial flexibility, including
our ability to access sources of external financing for our business. As a
result, our ability to meet our liquidity requirements and capital needs could
be materially adversely impacted, which could have a material adverse effect on
our business, financial condition, results of operations and liquidity.

RESTRICTIVE COVENANTS IN OUR DEBT INSTRUMENTS RESTRICT OR PROHIBIT OUR ABILITY
TO ENGAGE IN OR ENTER INTO A VARIETY OF TRANSACTIONS, WHICH COULD ADVERSELY
AFFECT US.

The agreements governing certain of our outstanding indebtedness contain various
restrictive covenants that limit our financial and operating flexibility. In
particular, these agreements restrict our ability to, among other things:

o    Incur additional indebtedness (including intercompany indebtedness);

o    Create liens and other encumbrances;

o    Enter into transactions with related parties; and

o    Sell or otherwise dispose of assets and merge or consolidate with another
     entity.

In addition, some of these agreements require us to maintain certain financial
ratios. These covenants and ratios could have an adverse effect on us by
limiting our operating flexibility and our ability to fund our operations. The
breach of any of these covenants and ratios would result in a default under the
applicable agreement which could result in the indebtedness under the agreement
becoming immediately due and payable. Any such acceleration would result in a
default under our other indebtedness subject to cross-acceleration provisions.
If this were to occur, we might not be able to pay our debts or obtain
sufficient funds to refinance them.

WE FACE INTENSE COMPETITION FROM NEW BRAND NAME PRODUCTS AND FROM LOWER-COST
GENERIC PRODUCTS.

The pharmaceutical industry is highly competitive. Our principal pharmaceutical
competitors consist of major international companies, many of which are larger
and have greater financial resources, technical staff, manufacturing, research
and development and marketing capabilities than Elan. Other competitors consist
of smaller research companies and generic drug manufacturers. A drug may be
subject to competition from alternative therapies during the period of patent
protection or regulatory exclusivity and, thereafter, it may be subject to
further competition from generic products. Additionally, generic competitors can
challenge existing patent protection or regulatory exclusivity. Generic
competitors do not have to bear the same level of research and development and
other expenses associated with bringing a new branded product to market. As a
result, they can charge much less for a competing version of our product.
Managed care organisations typically favour generics over brand name drugs, and
governments encourage, or under some circumstances mandate, the use of generic
products, thereby reducing the sales of branded products that are no longer
patent protected. Governmental and other pressures toward the dispensing of
generic products may rapidly and significantly reduce, or slow the growth in,
the sales and profitability of certain of our products not protected by patents
or regulatory exclusivity and may adversely affect our future results and
financial condition. For example, generic forms of Ceclor CD and Myambutol were
approved by the FDA and launched in 2001, significantly reducing the revenues
and profitability of these products. Generic forms of Zanaflex were launched in
2002. As a result, product revenue from Zanaflex declined from $53.7 million in
the first quarter of 2002 to $0.8 million in the first quarter of 2003.
Additionally, competitor products, including generic competitors' products, to
any of Elan's other products may become available. The launch of generic
versions of Elan's products may materially adversely affect our business,
financial condition and results of operations.

Our competitive position depends, in part, upon our continuing ability to
discover, acquire and develop innovative, cost-effective new products, as well
as new indications and product improvements protected by patents and other
intellectual property rights. We also compete on the basis of price and product
differentiation and through our sales and marketing organisation that provides
information to medical professionals and launches new products. If we fail to
maintain our competitive position, our business, financial condition and results
of operations may be materially adversely affected.

WE ARE DEPENDENT ON PATENT AND OTHER INTELLECTUAL PROPERTY RIGHTS.

Because of the significant time and expense involved in developing new products
and obtaining regulatory approvals, it is very important to obtain patent and
intellectual property protection for new technologies, products and processes.
Our success depends in large part on our continued ability to obtain patents for
our products and technologies, maintain patent protection for both acquired and
developed products, preserve our trade secrets, obtain and preserve other
intellectual property such as trademarks and copyrights, and operate without
infringing the proprietary rights of third parties.

Although we believe that we make reasonable efforts to protect our intellectual
property rights and to ensure that our proprietary technology does not infringe
the rights of other parties, we cannot ascertain the existence of all
potentially conflicting claims. Therefore, there is a risk that third parties
may make claims of infringement against our products or technologies. In
addition, third parties may be able to obtain patents that prevent the sale of
our products or require us to obtain a licence and pay significant fees or
royalties in order to continue selling our products.

We may in the future discover the existence of products that infringe upon
patents that we own or that have been licensed to us. Although we seek to
protect our trade secrets and proprietary know-how through confidentiality
agreements with our manufacturers, employees and consultants, we cannot prevent
our competitors from breaching those agreements or independently developing or
learning of our trade secrets.

WE ARE SUBJECT TO EXTENSIVE GOVERNMENT REGULATION, WHICH MAY ADVERSELY AFFECT
OUR ABILITY TO BRING NEW PRODUCTS TO MARKET AND MAY AFFECT OUR ABILITY TO
MANUFACTURE AND MARKET OUR EXISTING PRODUCTS.

The pharmaceutical industry is subject to significant regulation by state,
local, national and international governmental regulatory authorities. In the
United States, the FDA regulates the design, development, preclinical and
clinical testing, manufacturing, labelling, storing, distribution, import,
export, recordkeeping, reporting, marketing and promotion of our pharmaceutical
products, which include drugs, biologics and medical devices. Failure to comply
with regulatory requirements at any stage during the regulatory process could
result in, among other things, delays in the approval of applications or
supplements to approved applications, refusal of a regulatory authority to
review pending market approval applications or supplements to approved
applications, warning letters, fines, import and/or export restrictions, product
recalls or seizures, injunctions, total or partial suspension of production,
civil penalties, withdrawals of

RISK FACTORS
- --------------------------------------------------------------------------------

previously approved marketing applications or licences, recommendations by the
FDA or other regulatory authorities against governmental contracts, and criminal
prosecutions.

We must obtain and maintain approval for our products from regulatory
authorities before such products may be sold in a particular jurisdiction.
Currently, we are researching, developing and pursuing approval for a number of
products from a number of regulatory authorities, including Prialt and Antegren
in the United States and other territories. The submission of an application to
a regulatory authority with respect to a product does not guarantee that
approval to market the product will be granted. Each authority generally imposes
its own requirements and may delay or refuse to grant approval, even though a
product has been approved in another country. In our principal markets,
including the United States, the approval process for a new product is complex,
lengthy, expensive and subject to unanticipated delays. We cannot be sure when
or whether approvals from regulatory authorities will be received or that the
terms of any approval will not impose significant limitations that could
negatively impact upon the potential profitability of the approved product. Even
after a product is approved, it may be subject to regulatory action based on
newly discovered facts about the safety and efficacy of the product, on any
activities which regulatory authorities consider to be improper or on changes in
regulatory policy. Regulatory action may have a material adverse effect on the
marketing of a product, require changes in the product's labelling or even lead
to the withdrawal of the regulatory marketing approval of the product.

All facilities and manufacturing techniques used for the manufacture of products
and devices for clinical use or for sale in the United States must be operated
in conformity with current good manufacturing practices, or cGMPs, the FDA's
regulations governing the production of pharmaceutical products. There are
comparable regulations in other countries. Any finding by the FDA or other
regulatory authority that we are not in substantial compliance with cGMP
regulations or that we or our employees have engaged in activities in violation
of these regulations could interfere with the continued manufacture and
distribution of the affected products, up to the entire output of such products,
and, in some cases, might also require the recall of previously distributed
products. Any such finding by the FDA or other regulatory agency could also
affect our ability to obtain new approvals until such issues are resolved. The
FDA and other regulatory authorities conduct scheduled periodic regulatory
inspections of our facilities to ensure compliance with cGMP regulations. Any
determination by the FDA or other regulatory authority that we, or one of our
suppliers, are not in substantial compliance with these regulations or are
otherwise engaged in improper or illegal activities could have a material
adverse effect on our business, financial condition and results of operations.

In May 2001, Elan's wholly owned subsidiary, Elan Holdings, and Donal J. Geaney,
then chairman and chief executive officer of Elan, William C. Clark, then
president operations, and two then employees of Elan Holdings, Hal Herring and
Cheryl Schuster entered into a consent decree of permanent injunction with the
U.S. Attorney for the Northern District of Georgia, on behalf of the FDA,
relating to alleged violations of cGMP at Elan's Georgia, United States
facility. The facility currently manufactures verapamil hydrochloride, used in
the treatment of high blood pressure and other products. The consent decree does
not represent an admission by Elan Holdings or the officers or employees named
above of any of the allegations set forth in the decree. Under the terms of the
consent decree, which will continue in effect until at least May 2006, Elan
Holdings and the officers and employees named above are permanently enjoined
from violating cGMP regulations. In addition, Elan Holdings is required to
engage an independent expert, subject to FDA approval, to conduct inspections of
the facility at least annually through May 2004 in order to ensure the
facility's compliance with cGMP. The first of these inspections was completed
and reported upon by the independent expert to the FDA on 3 September 2002. A
corrective action plan was prepared and sent to the FDA in response to this
inspection. A second independent consultant audit occurred in May 2003 and Elan
is awaiting the report of this audit. During the term of the consent decree,
Elan expects that the facility will be subject to increased FDA inspections and,
under the terms of the consent decree, Elan will be required to reimburse the
FDA for its costs related to these inspections.

OUR RESEARCH AND DEVELOPMENT EFFORTS MAY NOT SUCCEED OR OUR COMPETITORS MAY
DEVELOP MORE EFFECTIVE PRODUCTS.

Our continued competitiveness is dependent upon our ability to successfully
develop and launch new products. We commit substantial resources on our research
and development activities and, in addition, spend considerable effort and funds
on a number of collaborations with third parties. Our ongoing investments in new
product launches and research and development for future products could produce
higher costs without a proportional increase in revenues.

In the pharmaceutical industry, the research and development process is lengthy
and involves a high degree of risk and uncertainty. This process is conducted in
various stages and, during each stage, there is a substantial risk that products
in our research and development pipeline, including our AD programmes, Antegren
and Prialt, will experience difficulties, delays or failures. In addition, in
2002, Wyeth and Elan suspended all clinical dosing with AN-1792, an experimental
immunotherapeutic under development for the treatment of AD which was in a Phase
IIa clinical study. On 1 March 2002, the companies decided not to resume further
dosing of AN-1792.


- --------------------------------------------------------------------------------
180


- --------------------------------------------------------------------------------

The commencement and rate of completion of clinical trials may be delayed by
many factors, including the inability to manufacture sufficient quantities of
qualified materials under cGMPs for use in clinical trials; slower than expected
rates of patient recruitment; the inability to adequately observe patients after
treatment; changes in regulatory requirements for clinical trials; the lack of
effectiveness during the clinical trials; unforeseen safety issues; delays,
suspension, or termination of the trial due to the institutional review board
responsible for overseeing the study at a particular study site; and government
or regulatory delays or "clinical holds" requiring suspension or termination of
the trial.

Even if we obtain positive results from preclinical or clinical trials, we may
not achieve the same success in future trials. Earlier stage trials are
generally based on a limited number of patients and may, upon review, be revised
or negated by authorities or by later stage clinical results. Historically, the
results from preclinical testing and early clinical trials have often not been
predictive of results obtained in later clinical trials. A number of new drugs
and biologics have shown promising results in initial clinical trials, but
subsequently failed to establish sufficient safety and effectiveness data to
obtain necessary regulatory approvals. Data obtained from preclinical and
clinical activities are subject to varying interpretations, which may delay,
limit or prevent regulatory approval. Clinical trials may not demonstrate
statistically sufficient safety and effectiveness to obtain the requisite
regulatory approvals for product candidates.

If we fail to research and develop commercially successful products, or if our
competitors develop more effective products, our business, financial condition
and results of operations could be materially adversely affected.

OUR SHAREHOLDERS COULD EXPERIENCE SUBSTANTIAL DILUTION IF THE HOLDERS OF OUR
LYONS REQUIRE US TO REPURCHASE A SIGNIFICANT PORTION OF THE LYONS IN DECEMBER
2003.

Holders of the LYONs may require us to purchase all or any portion of their
LYONs on 14 December 2003, 14 December 2008 and 14 December 2013 at a purchase
price equal to the issue price plus all accrued original issue discount up to
the purchase date. Subject to certain conditions, we may, at our option, elect
to pay for the LYONs in cash, by the delivery of ADSs, at then existing market
prices, or any combination of cash and ADSs. In the event that the trading price
of our ADSs does not increase substantially prior to 14 December 2003 and we
elect to pay a significant portion of the purchase price of any LYONs we are
required to purchase on that date in ADSs, our shareholders would experience
immediate and substantial dilution.

OUR BUSINESS EXPOSES US TO RISKS OF ENVIRONMENTAL LIABILITIES.

We use hazardous materials, chemicals and toxic compounds in our product
development programmes and manufacturing processes which could expose us to
risks of accidental contamination, events of non-compliance with environmental
laws, regulatory enforcement and claims related to personal injury and property
damage. If an accident occurred or if we were to discover contamination caused
by prior operations, we could be liable for cleanup obligations, damages or
fines, which could have an adverse effect on our financial condition and results
of operations.

The environmental laws of many jurisdictions impose actual and potential
obligations on us to remediate contaminated sites. These obligations may relate
to sites that we currently own, sites that we formerly owned or operated or
sites where waste from our operations was disposed. These environmental
remediation obligations could significantly reduce our operating results. In
particular, our accruals for these obligations could prove to be insufficient if
the assumptions underlying the accruals prove incorrect or if we are held
responsible for additional contamination.

Stricter environmental, safety and health laws and enforcement policies could
result in substantial costs and liabilities to us, and could subject our
handling, manufacture, use, reuse or disposal of substances or pollutants to
more rigorous scrutiny than is currently the case. Consequently, compliance with
these laws could result in significant capital expenditures, as well as other
costs and liabilities, which could materially adversely affect our business,
financial condition and results of operations.

OUR PRODUCTS MAY NOT BE REIMBURSED BY PUBLIC OR PRIVATE HEALTH INSURERS.

Even if we obtain a product approval, there is no assurance that public or
private health insurers will provide coverage for the product, will do so
promptly upon its approval or within a reasonable time after product approval or
that coverage will be competitive/favourable. If reasonable reimbursement is not
available for our products, our business, financial condition, and results of
operations could be materially adversely affected.

RISK FACTORS
- --------------------------------------------------------------------------------

WE ARE SUBJECT TO CONTINUING POTENTIAL PRODUCT LIABILITY.

Risks relating to product liability claims are inherent in the research,
manufacturing and marketing of our products. Any person who is injured as a
result of using one of our products may have a product liability claim against
us. Since we distribute and sell our products to a wide number of end users, the
risk of such claims could be material. Product liability claims could also be
brought by persons who took part in clinical trials involving our products.

We maintain product liability coverage for product liability claims. However,
this may not adequately protect us if there is a high occurrence of claims in
the future or if any future claims otherwise exceed the limits of our coverage.
A successful claim brought against us in excess of our insurance coverage could
have a material adverse effect on our business.

We may not be able to maintain product liability coverage on acceptable terms if
our claims experience results in higher rates, or if product liability insurance
otherwise becomes costlier because of general economic, market or industry
conditions. If sales of our products increase materially, or if we add
significant products to our portfolio, we will require increased coverage and
may not be able to secure such coverage at reasonable rates.

IF WE FAIL TO COMPLY WITH OUR REPORTING AND PAYMENT OBLIGATIONS UNDER THE
MEDICAID REBATE PROGRAM OR OTHER GOVERNMENTAL PRICING PROGRAMS, WE COULD BE
SUBJECT TO ADDITIONAL REIMBURSEMENTS, PENALTIES, SANCTIONS AND FINES WHICH COULD
HAVE A MATERIAL ADVERSE EFFECT ON OUR BUSINESS.

We participate in the U.S. Federal Medicaid rebate program established by the
U.S. Omnibus Budget Reconciliation Act of 1990, as well as several state
supplemental rebate programs. Under the Medicaid rebate program, we pay a rebate
to each state Medicaid program for our products that are reimbursed by those
programs. The amount of the rebate for each unit of product is set by law as a
minimum 15.1% of the average manufacturer price ("AMP") of that product, or if
it is greater, the difference between AMP and the best price available from us
to any customer. The rebate amount also includes an inflation adjustment, if
necessary.

As a manufacturer currently of single source, innovator multiple source and
non-innovator multiple source products, rebate calculations vary among products
and programs. The calculations are complex and, in certain respects, subject to
interpretation by us, governmental or regulatory agencies and the courts. The
Medicaid rebate amount is computed each quarter based on our submission to the
Centers for Medicare and Medicaid Services at the U.S. Department of Health and
Human Services of our current AMP and best price for each of our products. The
terms of our participation in the program impose an obligation to correct the
prices reported in previous quarters, as may be necessary. Any such corrections
could result in an overage or underage in our rebate liability for past
quarters, depending on the direction of the correction. In addition to
retroactive rebates (and interest, if any), if we were found to have knowingly
submitted false information to the government, the statute provides for civil
monetary penalties in the amount of $100,000 per item of false information.
Governmental agencies may also make changes in program interpretations,
requirements or conditions of participation, some of which may have implications
for amounts previously estimated or paid. Based upon our past practice and
experience, to the extent that we were required to correct prices reported in
previous quarters, we would not expect such corrections to have a material
adverse affect on our business, financial condition, results of operations or
liquidity.

U.S. Federal law requires that any company that participates in the Medicaid
rebate program extent comparable discounts to qualified purchasers under the
Public Health Services, or "PHS," pharmaceutical pricing program. The PHS
pricing program extends discounts comparable to the Medicaid rebates to a
variety of community health clinics and other entities that receive health
services grants from the PHS, as well as hospitals that serve a disproportionate
share of poor.

MEMORANDUM AND ARTICLES OF ASSOCIATION
- --------------------------------------------------------------------------------








- --------------------------------------------------------------------------------

OBJECTS

The Company's objects, which are detailed in its Memorandum of Association
include, but are not limited to, manufacturing, buying, selling and distributing
pharmaceutical products. The Company's registered number is 30356.


DIRECTORS

Subject to certain limited exceptions, directors may not vote on matters in
which they have a material interest. In the absence of an independent quorum,
the directors may not vote compensation to themselves or any member of the board
of directors. Directors are entitled to remuneration as shall, from time to
time, be voted to them by ordinary resolution of the shareholders and to be paid
such expenses as may be incurred by them in the course of the performance of
their duties as directors. Directors who take on additional committee
assignments or otherwise perform additional services for the Company, outside
the scope of their ordinary duties as directors, shall be entitled to receive
such additional remuneration as the board may determine. The directors may
exercise all of the powers of the Company to borrow money. These powers may be
amended by special resolution of the shareholders. One-third of the board shall
retire at each Annual General Meeting. A director is not required to retire at
any set age and may offer themselves for re-election at any meeting where they
are deemed to have retired by rotation. There is no requirement for a director
to hold shares.


MEETINGS

The Annual General Meeting shall be held in such place and at such time as shall
be determined by the board, but no more than 15 months shall pass between the
dates of consecutive Annual General Meetings. Directors may call Extraordinary
General Meetings at any time. Extraordinary General Meetings may also be
requisitioned by the members in accordance with the Company's Articles of
Association and Irish company law. Notice of an Annual General Meeting (or any
special resolution) must be given at least 21 clear days prior to the scheduled
date and, in the case of any other general meeting, with not less than 14 clear
days notice.


RIGHTS, PREFERENCES AND DIVIDENDS ATTACHING TO SHARES

All unclaimed dividends may be invested or otherwise made use of by the
directors for the benefit of the Company until claimed. All of the shareholders
entitled to attend and vote at the Annual General Meeting are likewise entitled
to vote on the re-election of directors. The Company is permitted under its
Memorandum and Articles of Association to issue redeemable shares on such terms
and in such manner as the shareholders may determine by special resolution. The
liability of the shareholders to further capital calls is limited to the amounts
remaining unpaid on shares.


ACTIONS NECESSARY TO CHANGE THE RIGHTS OF SHAREHOLDERS

The rights attaching to the different classes of shares may be varied by special
resolution passed at a class meeting of that class of shareholders. The
additional issuance of further shares ranking pari passu with, or subordinate
to, an existing class shall not, unless specified by the Articles or the
conditions of issue of that class of shares, be deemed to be a variation of the
special rights attaching to that class of shares.


LIMITATIONS ON THE RIGHT TO OWN SHARES

There are no limitations on the right to own shares in the Memorandum and
Articles of Association. However, there are some restrictions on financial
transfers between Ireland and other specified countries, more particularly
described in the section on "Exchange Controls and Other Limitations Affecting
Security Holders" on page 174.
