extension on 25 April 2001.

"Discussions with Industry Canada are ongoing and we remain firmly committed to

Notes to editors
Shire Pharmaceuticals Group plc
Shire is a rapidly growing international specialty pharmaceutical company with a
strategic focus on four therapeutic areas: central nervous system disorders,
metabolic diseases, oncology and gastroenterology. The Group has a sales and
marketing infrastructure with a broad portfolio of products, with its own direct
marketing capability in the US, Canada, UK, Republic of Ireland, France,
Germany, Italy and Spain and with plans to add Japan by 2004. Shire also covers
other significant pharmaceutical markets indirectly through distributors and
sales coverage continues to grow.

Shire's global search and development expertise has to date successfully
provided eight marketed products, of which Reminyl* for the treatment of
Alzheimer's disease has recently been launched in the UK, its first market in
Europe. The National Institute of Clinical Excellence (NICE) recommended on 19
January 2001 that treatment for Alzheimer's disease be made available through
the National Health Service (NHS) in the UK. Additionally, on 28 February 2001
Reminyl* received Food and Drug Administration (FDA) approval to be marketed in
the US. The current pipeline of 17 projects includes three projects in
registration in various countries, plus the delivery of the first regulatory
submission for Foznol* to a Reference Member State in the EU Mutual Recognition
Procedure on 13 March 2001, and 6 others that are post Phase II. Shire is
actively seeking to acquire further marketed products and development projects
to enhance the potential for future growth. Shire's M&A activity has resulted in
five completed mergers and acquisitions during the last six years.

On 11 December 2000, Shire entered into an agreement to merge with BioChem
Pharma Inc. to form a leading global specialty pharmaceutical company. More
details on this proposed merger and other aspects of the company are available
on the Shire website at Error! Bookmark not defined.

OVERVIEW OF FINANCIAL RESULTS

Group revenues for the first quarter increased by 31% to $155.6 million (Q1
2000: $119.0 million). The Group recorded income before tax and APB25 charge of
$40.1 million, up 50% (Q1 2000: $26.7 million) and diluted earnings per ordinary
share pre APB25 charge of 10.7 cents or 32.1 cents per ADS, up 46% (Q1 2000: 7.3
cents per ordinary share or 22.0 cents per ADS). Net income (after APB25 charge
of $2.1 million) was $26.0 million (Q1 2000: $4.3 million net loss after APB25
charge of $23.2 million).

Sales and marketing

Product sales, at $151.4 million, increased by 34% over Q1 2000. Sales of
Adderall* were $70.1 million, representing growth of 29% on the comparative
period in 2000, which included some stock-building by wholesalers ahead of
anticipated price increases. Adderall* had a 33.3% share of the prescription
market for Attention Deficit Hyperactivity Disorder (ADHD) in the US in March
2001 (March 2000: 29.7%) and continues to be the brand leader in the US market
for ADHD.

Sales of Agrylin*, the only US product licensed for the treatment of
thrombocythaemia, were $17.1 million, a 56% increase on Q1 2000 sales of $11.0
million, when sales were slightly below trend due to wholesaler de-stocking.
Shire achieved a prescription share of 20.4% of the total US Agrylin, Hydrea and
generic hydroxyurea market in March 2001, compared to 14.3% for the month of
March 2000.

Sales of Pentasa*, for the treatment of ulcerative colitis, were $14.4 million,
39% higher than the comparable period last year, when sales were below trend due
to wholesaler de-stocking following a price increase in Q4 1999. Pentasa* had a
prescription share of 17.8% of the US oral mesalamine/olsalazine market in March
2001, compared to 18.0% in March 2000.

Sales of ProAmatine*, for the treatment of postural hypotension, were $7.6
million, 112% higher than Q1 2000 sales of $3.6 million, when sales were also
below trend due to wholesaler de-stocking following a price increase in Q4 1999.
The US prescription market for ProAmatine* and Florinef prescriptions indicates
that ProAmatine* had a 22.1% share for the month of March 2001, an increase from
19.5% in March 2000.

Carbatrol*, containing carbamazepine, recorded sales growth of 72% from sales of
$5.6 million in Q1 2000 to $9.6 million in Q1 2001. This translates to 32.5% of
the US extended release carbamazepine prescription market in March 2001,
compared to 26.0% in March 2000.

Licensing

Licensing and development fees in the first quarter fell by 38% to $3.0 million
(Q1 2000: $4.9 million) and included one-time receipts of third party milestone
payments in respect of Reminyl* Food and Drug Administration (FDA) approval and
SLI drug



delivery contracts. The quarter on quarter decrease is mainly due to the
reduction in development stage activities for Reminyl* and hence the ending of
reimbursement revenues for actual costs incurred on bulb-related raw material.
Royalties increased by $0.3 million to $0.9 million (Q1 2000: $0.6 million).


Cost of sales and operating expenses

Gross margin on product sales, at 82%, was consistent with Q1 2000. The higher
margin products, particularly Adderall* and Agrylin* represented approximately
57% of total product sales in Q1 2001, also consistent with Q1 2000.

R&D expenditure for the first quarter increased by 4% to $27.2 million.
Expressed as a percentage of revenues, R&D expenditure was 17% in Q1 2001
compared to 22% in Q1 2000 and 21% for full year 2000. R&D expenditure was
particularly high in Q1 2000 due to the upfront payment for the in-licensing of
SPD 421 from D-Pharm. The relatively low R&D to revenue ratio in Q1 2001 is
mainly related to phasing of project costs resulting in lower than usual costs
during the quarter.

Selling, general and administrative (S,G&A) expenses, excluding the effects of
an APB25 charge, increased by 41% to $49.5 million (Q1 2000: $35.2 million). As
a percentage of product sales S,G&A expenses increased by 2% to 33%. This
increase reflects the growth in the US sales force since Q1 2000 and increased
marketing activities in respect of the anticipated Adderall XR* launch.

The APB25 charge for the quarter was $2.1 million. This substantial reduction
compared to the Q1 2000 charge of $23.2 million reflects minor amendments to the
executive share option scheme effective from March 2000.

Depreciation and amortisation increased by 13% to $8.6 million (Q1 2000: $7.6
million). This increase is attributable to the purchase of several new products
since March last year.

Taxation

The effective rate of tax on the profits for the quarter pre APB25 is 30% (Q1
2000: 29%). The company has recorded net deferred tax assets of approximately
$26.8 million.

Cash flow

Net cash inflow from operating activities of $58.0 million provided funding for
two product acquisitions in Europe ($18.3 million) and tangible fixed asset
additions of $1.5 million. Cash inflow from financing activities of $2.1 million
related to employee stock option exercises.

Cash, cash equivalents, marketable securities and other current assets at 31
March 2001 amounted to $225.4 million. After deduction of borrowings this gives
a net cash position of $97.5 million.



PROJECTS UNDER DEVELOPMENT

Central nervous system disorders

Alzheimer's disease
Reminyl* was launched in the UK in September 2000. In January 2001, the UK
National Institute of Clinical Excellence (NICE) announced that treatments for
Alzheimer's disease should be made available as part of the management of
patients with mild to moderate Alzheimer's disease within the UK. This was
followed on 28 February 2001 by approval from the Food and Drug Administration
(FDA) for Reminyl* in the US. Janssen Pharmaceutica and Ortho-McNeil
Pharmaceutical will be marketing Reminyl* in this market and intend to make the
product available on prescription from May 2001.

By 31 March 2001, Reminyl* had been launched in 11 countries, including the UK
and Ireland. A number of further launches are planned over the coming months.

ADHD
New pivotal data on the once daily formulation of Adderall*, SLI 381, under
development for the treatment of ADHD, have been accepted as a platform
presentation at the annual meeting of the American Psychiatric Association
(APA). The oral presentation of safety and efficacy results will take place on
Wednesday, 9 May, at 11:00 am at the APA's 2001 annual meeting in New Orleans,
at which point Shire will publish the relevant posters. The once daily
medication, currently known by its project designation, SLI 381 (proposed Trade
Mark Adderall XR), is a novel formulation of Adderall* (mixed salts of a
single-entity amphetamine product) that incorporates Shire's Microtrol(TM)
advanced drug delivery system.


Oncology/haematology

Thrombocythaemia
On 3 January 2001, Shire announced that the European Commission had granted
orphan drug designation to anagrelide for the treatment of essential
thrombocythaemia. This designation covers the EU, plus Norway and Iceland, and
provides up to 10 years market exclusivity for the product following Marketing
Authorisation Approval. Orphan drug status already applies to anagrelide in the
US, where the product is marketed as Agrylin*, and in Japan where it will run
for 10 years following marketing approval.


Metabolic diseases

Hyperphosphataemia
The first regulatory submission for Foznol* (lanthanum carbonate) was delivered
to a Reference Member State in the EU Mutual Recognition Procedure on 13 March
2001. Foznol is being developed for the treatment of hyperphosphataemia in
patients with chronic renal failure.




Future Prospects

In respect of the proposed merger with BioChem Pharma Inc, although the current
review period with Industry Canada expires on 27 April 2001, Shire requested an
extension on 25 April 2001.

Discussions with Industry Canada are ongoing and Shire remains firmly committed
to obtaining the Canadian Minister of Industry's approval for the proposed
merger with BioChem Pharma Inc.

Progress towards the launch of Adderall XR* continues and this will lead to
ongoing marketing expenditure. R&D expenditure as a percentage of revenue is
expected to move back towards historic ranges in subsequent quarters.

With the forthcoming US launch of Reminyl* expected and the recent regulatory
filing for Foznol* in Europe, management remains confident about the company's
future growth prospects.

2.       Net income/(loss) per share

Basic net income/(loss) per share is based upon the net income/(loss) available
to common stockholders divided by the weighted average number of common shares
outstanding during the period. Diluted net income/(loss) per share is based upon
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.

The following table sets forth the computation for basic and diluted net
income/(loss) per share:
