(1)  The 2002 US GAAP results have been restated to reflect the disposal of our
     `Over-The-Counter' (OTC) business, which has been accounted for as a
     discontinued operation. All 2002 figures down to net income from continuing
     operations exclude the OTC business, while 2002 net income and EPS figures
     include the OTC results.

(2)  Average exchange rates for Q2 2003 and 2002 were $1.62: (pound)1.00 and
     $1.47: (pound)1.00 respectively.

Matthew Emmens, Chief Executive, said:

"Strong financial performance continued in the second quarter.

"Since joining Shire in March, I have led a detailed strategic review. Shire has
robust franchises in its core areas and has a successful track record in
marketing to specialist physicians. With that in mind, we have now made some
important decisions that will shape our future.

"Our goal is to become the leading company in meeting the needs of the
specialist physician. With the right products, small sales forces can deliver
impressive sales. This is our core competency. By replicating this success in
other `specialty arms' we believe we can achieve our growth aspirations.

"This commercial platform has implications for both our R&D and business
development efforts. Our R&D focus will shift to fewer, later stage (lower risk)
projects and center on areas where we have commercial presence. Business
development efforts will intensify and we will use our considerable cash
reserves to enhance our product line and specialty reach.

"Several immediate actions will be taken as a result of the strategic review. We
intend to spin out the vaccines business as an independent company. Our early
stage research (lead optimisation) unit will be closed. As a result of exiting
oncology and anti-infectives research, we will seek to out-license TROXATYL and
partner SPD754. Furthermore, we will significantly enhance our M&A effort -
targeting acquisitions in the US, including larger scale transactions. In
addition to these actions, I have initiated projects that will better integrate,
coordinate and rationalize our global business activities.

                                                                               1



"Concentrating our business in a more focused way will create a stronger Shire
and position us for continued growth. Our strategy is aimed at achieving growth,
on average, in the mid-teens range beyond 2003."

New R&D focus - later stage, lower risk

The exit from the Vaccines business will remove several promising but early
stage projects from the portfolio. Shire will increasingly focus investment in
R&D onto lower risk, later stage opportunities which can be fully funded and
which will have the highest probability of reaching the market in the shortest
time. Shire's short-term growth will come from the launch of products from its
own pipeline, from M&A and from in-licensing.

The early stage research lead optimisation research group, based in Laval Canada
will be closed down with the loss of approximately 120 jobs. A re-structuring
provision of approximately $12 million will be booked mainly in Q3 2003.
Re-structuring costs, net of savings, for the full year 2003 are estimated to be
around $7 million, with the major element being non-cash asset write-downs.
Ongoing savings from 2004 are estimated to be approximately $15 million per
annum.

Oncology and anti-infectives will no longer be therapeutic areas of focus in R&D
for the Company. Shire will seek to out-license TROXATYL (for the treatment of
acute myeloid leukaemia and pancreatic cancer). Shire will continue to develop
the anti-infectives project SPD754 (for HIV treatment) while seeking partnership
opportunities to more effectively leverage this asset.

Vaccines

Shire intends to spin off the vaccines business, given its earlier stage of
development and the different dynamics in the vaccine market. Shire anticipates
concluding this process by the end of H1 2004. In the first six months of 2003,
this business had an operating loss of $14.5 million including R&D expenditure
of $7.8 million. This is currently a Canadian commercial business, which
comprises the NEISVAC-C vaccine for meningitis C and the FLUVIRAL flu vaccine,
which is also in development for markets outside Canada (SPD707). The R&D
portfolio comprises SPD701 for influenza, SPD703 for pneumonia, SPD704 for
meningitis and SPD705 for opportunistic infections all in phase I.


Second Quarter 2003 and Recent Events Highlights

     o    Q2 2003 revenues up 21% to $299.0 million, diluted earnings per ADS up
          10% to 38.4c.

     o    ADDERALL XR(R) sales up 35% on the same period last year, totalling
          $102.4 million; the ADDERALL(R) brand has remained the leading ADHD
          brand in the US with 26%(6) prescription share in Q2 2003.

     o    Strong growth in 3TC sales and positive foreign exchange movements (up
          22% to $37.5 million) were major contributors to an overall increase
          in royalties in Q2 2003, up 28% to $51.8 million.

     o    Shire received positive Committee for Proprietary Medicinal Products
          (CPMP) opinion for XAGRID(R) in Europe.

     o    Continued dialogue with the US Food and Drug Administration (FDA) with
          regard to FOSRENOL(R); pre-approval data remains on course for
          submission in the US and EU.

     o    Rights acquired to five products from DRAXIS Health for the Canadian
          market in July 2003.


New Non Executive Director

Shire has announced the appointment of Robin Buchanan as Non Executive Board
Director. Mr Buchanan is the Senior Partner of the London office of business
consultants, Bain & Company


                                                                               2


and a member of Bain's worldwide management committee; he is a British citizen
and lives in the UK.

Future prospects

Shire remains comfortable with previous FY 2003 guidance, provided at Q1 2003
results, of mid to high teens revenue growth, operating margins of circa 30% and
high single digit to low double digit EPS growth. This excludes a potential 3
cents negative impact in relation to the closure of the Lead Optimisation
business.

OVERVIEW OF US GAAP FINANCIAL RESULTS

Introduction

The results for the second quarter ended 30 June 2002 have been restated to
reflect the disposal of our OTC business, accounted for as a discontinued
operation in accordance with generally accepted accounting principles in the
United States of America (US GAAP). In accordance with US GAAP guidelines, 2002
figures from revenues down to income from continuing operations exclude the
results of the OTC business, while 2002 net income and earnings per share
include the results of the OTC business.

Revenues from continuing operations for the second quarter ended 30 June 2003
increased by 21% to $299.0 million (Q2 2002: $248.1 million).

The Company recorded net income of $65.5 million, an increase of 10% compared to
the three months ended 30 June 2002. Diluted earnings per common share were 12.8
cents, or 38.4 cents per ADS, an increase of 10% over Q2 2002.

Operations generated cash inflows from operating activities of $1.8 million
during the second quarter of 2003. This was primarily due to an increase of
$55.7 million in accounts receivable resulting from the phasing of wholesaler
buying and a decrease of other liabilities of $16.9 million as a result of
periodic tax payments.

The Company initiated a share re-purchase programme during the quarter, buying
back 7.6 million common shares at a total cost of $52.4 million.

Cash, cash equivalents and marketable securities at 30 June 2003 amounted to
$1,185.2 million (31 December 2002: $1,213.8 million). After deduction of
borrowings, this translates to a net cash position of $806.5 million (31
December 2002: $805.7 million). Where appropriate, this may be used to further
enhance our portfolio through product and project acquisitions.

Product sales

For the quarter ended 30 June 2003, product sales increased $39.6 million to
$246.5 million (Q2 2002: $206.9 million) and represented 82% of total revenues.
During the early part of Q2 2003, Shire experienced aggressive wholesaler
de-stocking, significantly beyond the stock-build of $15 million announced in Q1
2003. This significant de-stocking below normal levels was corrected later in
the quarter following the initiation of a wholesaler promotional campaign
intended to normalise inventory levels. The Company estimates that Q2 2003
product revenues approximated prescription-based demand for the quarter except
for sales of ADDERALL ($5 million) and PROAMATINE ($5 million). ADDERALL
benefited from a promotional campaign intended to decrease inventories of
short-dated product, while PROAMATINE benefited from increased sales due to the
timing of order flow. The combined amount of Q2 revenues in excess of demand was
approximately $10 million which, in combination with the wholesaler stocking
reported in Q1 2003, is expected to reverse prior to year end.

                                                                               5


CNS Franchise

ADDERALL XR and ADDERALL

Total ADDERALL franchise sales in Q2 2003 were $121.6 million, an increase of
17% over Q2 2002 ($104.1 million). Over the same period, total ADDERALL
franchise prescriptions grew by approximately 16%(6), despite the entry of
generic versions of ADDERALL last year, as well as increased competition within
the ADHD market overall.

Sales of ADDERALL XR in Q2 2003 were $102.4 million, an increase of 35% over Q2
2002 ($75.8 million). ADDERALL XR prescriptions increased 62%(6) between
periods driven by successful conversion of ADDERALL business to the improved
ADDERALL XR formulation and overall market growth. The difference between
reported growth and prescription growth is largely due to a strong Q2 2002 that
included launch stock related to new strengths of ADDERALL XR. Revenues of
ADDERALL XR in Q2 2003 were broadly in line with underlying prescription demand.

Increased competitor activity has had a positive impact on the US ADHD market
growth, which reached 18%(6) for Q2 2003 over the prior year period.
Notwithstanding this increase in competition, ADHD physicians have continued to
recognise the strengths of the ADDERALL brand, which maintained its leading
position in the ADHD market with a 26%(6) prescription share during Q2 2003.

Sales of ADDERALL were $19.2 million in Q2 2003, down 32% from Q2 2002 ($28.3
million). Overall prescriptions were down approximately 59%(6) between periods.
In Q2 2003, Shire offered wholesalers short-dated product on a non-returnable
basis. The Company estimates that this offer increased ADDERALL revenues by $5
million over normal Q2 wholesaler buying patterns.

CARBATROL

CARBATROL sales increased by $1.3 million or 11%, year on year, versus a 1%(6)
increase in prescriptions. Q2 2003 sales benefited from a price increase
implemented in April 2003. The Company believes that wholesaler inventory levels
are fully adjusted to reflect current demand levels.

Following recommencement of promotional efforts in Q1 2003, Shire has grown
CARBATROL's share of the extended release carbamazepine market from 36%(6) in Q2
2002 to 38%(6) in Q2 2003. Total prescription volume for carbamazepine products
has remained stable between Q1 2003 and Q2 2003, and Shire will continue to
monitor progress in this area.

The FDA website indicates that a generic company has filed an abbreviated new
drug application for CARBATROL 300mg. Shire has no further information at this
time.

Other Franchises

AGRYLIN

AGRYLIN sales growth of 24% in Q2 2003 was supported by 8%(6) US prescription
growth, and strong growth in sales from outside the US. While Q2 2003 revenues
were in line with underlying prescription demand, wholesaler inventories remain
somewhat above normal levels and the Company expects wholesaler de-stocking to
adversely impact sales trends in Q3 or Q4 2003.

AGRYLIN remains the only product specifically approved for essential
thrombocythemia in the US. The anticipated pediatric extension for AGRYLIN could
extend its orphan drug exclusivity from March 2004 to September 2004, after
which time it is expected to face generic competition. The expected launch of
XAGRID (the trade name of AGRYLIN used in the EU) will continue to drive growth
from markets outside the US.

                                                                               6


PENTASA

The 15% growth in PENTASA sales revenue compared to Q2 2002, versus a 3%(6) fall
in prescription demand for the same period, is largely related to wholesaler
stocking movements in Q2 2002 and the favourable impact of an April 2003 price
increase. While Q2 2003 revenues were in line with underlying prescription
demand, wholesaler inventories remain somewhat above normal levels and the
Company expects wholesaler de-stocking to adversely impact sales trends in Q3 or
Q4 2003.

Although its formal indication is for mild to moderately active ulcerative
colitis, PENTASA continues to see the majority of its use in Crohn's disease.

PROAMATINE

Supported by 12%(6) prescription growth, the remainder of PROAMATINE's total 68%
growth during the quarter is attributable to wholesaler buying patterns. The
Company estimates that wholesalers stocked approximately $5 million of product
in excess of underlying prescription demand. The impact of wholesaler
de-stocking prior to year-end and/or the onset of generic competition could
adversely impact comparative sales trends in Q3 or Q4 2003.

While PROAMATINE grew its share of the PROAMATINE and fludrocortisone acetate
market from 24%(6) in Q2 2002 to 27%(6) in Q2 2003, its Orphan Drug Status will
expire in September 2003, allowing the entry of potential generic competition.

Royalties

Royalty revenue increased 28% to $51.8 million for Q2 2003 (Q2 2002: $40.5
million) as a result of strong sales and positive foreign exchange movements.

For the products 3TC and ZEFFIX, treatments for HIV infection and chronic
hepatitis B respectively, Shire receives royalties from GSK on worldwide sales,
with the exception of Canada, where a commercialisation partnership with GSK
exists.

The nucleoside analogue market for HIV has continued to exhibit solid
double-digit growth in recent months. This growth is supported by increases in
the number of individuals living with HIV, as well as reduced mortality due to
more effective treatment regimens.

With the recent introduction of only the second antiviral agent in the US for
hepatitis B infection, market dynamics in the US are expected to change. This
introduction is not expected to have a dramatic near term impact on royalties,
as the majority of ZEFFIX sales continue to be made in Asia-Pacific markets.

Royalty revenue is also received in respect of REMINYL from Johnson & Johnson,
and in respect of a number of hormone replacement therapy products from various
licensees.

REMINYL is the newest treatment available for the treatment of mild to
moderately severe dementia of the Alzheimer's type. It is currently growing well
in the Alzheimer's market, while progress continues for other indications and
formulations.

Cost of product sales


                                                                               7



For the second quarter ended 30 June 2003, cost of product sales amounted to 16%
of product sales (Q2 2002: 14%). The increase over the prior year period is
primarily driven by the sales mix in the quarter. The cost of product sales is
15% of product sales for the six months ended 30 June 2003 (2002: 14%).

Research and development (R&D)

R&D expenditure increased to $50.1 million in Q2 2003 from $46.8 million in Q2
2002, representing an increase of 7%. Expressed as a percentage of total
revenues, R&D expenditure for the quarter was 17% (Q2 2002: 19%).

Selling, general and administrative (SG&A)

SG&A expenses increased from $84.3 million in Q2 2002 to $102.6 million in Q2
2003, an increase of 22%. As a percentage of product sales, these expenses were
42% (2002: 41%).

Q2 2003 SG&A expenses included continued additional promotional spend for
ADDERALL XR in relation to sustained competitor activity, as well as for the
ongoing relaunch of CARBATROL. As the benefit of this promotional spend is
realised, this high level of spend is expected to moderate over the remainder of
the year.

Depreciation and amortisation

The depreciation charge for Q2 2003 was $4.0 million, an increase of $0.7
million compared to 2002. Amortisation charges were $9.1 million, an increase of
$0.3 million compared to Q2 2002.

Interest income and expense

For the three months ended 30 June 2003, the Company received interest income of
$4.3 million (Q2 2002: $4.8 million). Interest expense increased from $1.8
million in Q2 2002 to $2.7 million in 2003, primarily relating to costs
associated with partial buy back of the convertible notes.

Other (expense)/income, net

For the three months ended 30 June 2003, other expense totalled $3.7 million (Q2
2002: $0.9 million). The expense is primarily attributable to investment
write-downs for other than temporary impairment of $4.5 million.

Taxation

For Q2 2003 income taxes increased $4.2 million to $25.5 million from $21.3
million for Q2 2002. Our effective tax rate was 28% for Q2 2003 (2002: 27%). We
have net deferred tax assets of $58.9 million at 30 June 2003. Realisation is
dependent upon generating sufficient taxable income to utilise such assets.
Although realisation of these assets is not assured, management believes it is
more likely than not that the deferred tax assets will be realised.

Equity in (losses)/earnings of equity method investees

We received $0.9 million representing our 50% share of earnings from our
antiviral commercialisation partnership with GSK in Canada (Q2 2002: $1.9
million) and we incurred a loss of $2.1 million representing our 50% share of
the losses of our commercialisation partnership with Qualia Computing Inc (Q2
2002: $nil).

Discontinued operations

The Company completed the divestment of its OTC portfolio on 27 December 2002.
These products were originally acquired in 1999 as a result of the Company's
merger with Roberts Pharmaceutical Corporation. In accordance with US GAAP the
2002 results have been restated to present the results of these products as a
discontinued operation.

                                                                               8



The OTC business contributed net income of $1.6 million for the three months
ended 30 June 2002, which is included in the reported net income number for
2002.

R&D OVERVIEW

As part of its strategic review Shire will refocus its portfolio onto lower
risk, later stage opportunities and to build its franchise in CNS, GI and in
renal, but the refocus and prioritisation will enable Shire to alter the risk
balance profile of the portfolio to improve the likely return on this
investment.

R&D Activities from May to July 2003

RENAL

FOSRENOL
Additional data collection and analysis is underway and Shire will update as
soon as further new information is available.

HAEMATOLOGY

XAGRID
XAGRID (anagrelide hydrochloride) received a positive opinion from the European
Committee for Proprietary Medicinal Products (CPMP) for XAGRID to be used in the
treatment of Essential Thrombocythemia (ET).

Once marketing approval is received, pricing and reimbursement negotiations will
commence with individual national authorities prior to launch. The drug is
already marketed by Shire in the US and a range of other territories under the
trademark AGRYLIN. Total sales of AGRYLIN in 2002 were $119.2 million, up 39% on
2001. It is estimated by Shire that 40,000 patients suffering from ET across the
European Union (EU) member states would be eligible for treatment with XAGRID.
There is currently no other platelet-reducing treatment approved for the
treatment of ET across the EU.

Essential Thrombocythemia is a condition arising from a chronic disorder of bone
marrow, which leads to an increased production of blood platelets. Excessive
platelet production can result in abnormal blood clot formation and bleeding,
thereby increasing the risk of stroke, heart attack and gastrointestinal
bleeding.

CENTRAL NERVOUS SYSTEM (cns)

METHYPATCH
At the end of February 2003, Shire announced the acquisition from Noven
Pharmaceuticals, Inc. (Noven) of the worldwide sales and marketing rights to
METHYPATCH, a supplemental product for Shire's ADHD franchise. As previously
announced on 28 April 2003, Noven has received a not approvable letter for
METHYPATCH. Noven have an ongoing dialogue with the FDA and Shire is working
with Noven to resolve the issues.

ADDERALL XR
Shire submitted an sNDA for ADDERALL XR in the treatment of adult ADHD on 19
December 2002. The review with the FDA is underway with an expected Prescription
Drug User Fee Act date at the end of October 2003. Shire estimates adult ADHD
treatment rates to be around 5% in the US, thus there is a significant
opportunity for ADDERALL XR in the approximately 8 million adult ADHD patient
population.

GASTROINTESTINAL

As announced previously, SPD476 for the treatment of Ulcerative Colitis
continues to show promising results. Phase III trials are on schedule to begin
during the second half of 2003.



                                                                               9




ANTI-INFECTIVES

SPD754
SPD754 is a cytidine analogue nucleoside reverse transcriptase inhibitor (NRTI)
in development for the treatment of HIV, including HIV resistant to other
NRTI's. The first phase II study with SPD754 was recently presented at the 2nd
International AIDS Society (IAS) meeting in Paris (July 2003).

This randomised, double blind trial evaluated the anti-viral activity and safety
of 4 doses of SPD754 versus placebo in 63, treatment-naive, HIV infected
subjects. SPD754 was shown to have potent anti-viral activity and to be well
tolerated with an adverse event profile similar to that of placebo.

After 7 and 10 days' monotherapy, SPD754 reduced the mean Viral Load (VL) by up
to 1.44 and 1.65 log respectively. Up to 92% of subjects achieved >1 log drop in
their VL. All active doses were statistically significantly superior to placebo.

SPD754 did not select for known NRTI-resistant mutations in this setting.
Overall, the drug was well tolerated, with no indication of dose-limiting
adverse events.

Shire is excited at the prospect of this compound and is keen to evaluate
potential development and marketing partnerships to ensure the product can be
rapidly made available to patients.

ONCOLOGY

As a result of the strategic review, Shire has decided to out-license TROXATYL.



                                                                              10

Basic earnings per share is based upon the net income available to common
stockholders divided by the weighted-average number of common shares outstanding
during the period.

Diluted earnings per share is based upon net income available to common
stockholders divided by the weighted-average number of common shares outstanding
during the period and adjusted for the effect of all dilutive potential common
shares that were outstanding during the period.

Selected Notes to the Unaudited and Unreviewed UK GAAP Financial Statements

(1) Earnings per share

Earnings per share has been calculated by dividing the profit on ordinary
activities after taxation for each period by the weighted average number of
shares in issue during those periods.

The weighted average number of shares used in calculating fully diluted earnings
per share has been adjusted for the effects of all dilutive potential ordinary
shares.

The $400 million convertible loan note is excluded from the calculation of
weighted average number of shares for fully diluted earnings per share in 2003
and 2002 as it was not dilutive. The zero coupon convertible loan note included
in 2002 has no impact on the numerator for fully diluted earnings per share.

The warrants to purchase approximately 1.4 million common shares for the 3 and 6
months ended 30 June 2003 were anti-dilutive and were therefore excluded from
the computation of diluted earnings per share.
