For Immediate Release

                     Shire Chief Executive Stahel to Leave;
                  Will Remain In Post Until Successor Is Found
                Global Search for Candidate to Begin Immediately

BASINGSTOKE, UK - 29th October 2002 - Shire Pharmaceuticals Group PLC (LSE: SHP,
NASDAQ ADR: SHPGY, TSX: SHQ) today announced that Rolf Stahel will leave the
board, and the company, as soon as a successor is found. The Board will commence
a global search for a new chief executive immediately.

"Shire's future prospects are strong," Mr. Stahel said. "After leading six
mergers and acquisitions and with the successful launch of Adderall XR this
year, I now believe this is the right time to prepare to hand the company over
to a successor."

Acknowledging Mr. Stahel's contributions, Dr. James Cavanaugh, chairman, said,
"The Board is grateful for Rolf's nearly nine years of service during the period
when the company grew from $3 million of annual sales to $878 million at the end
of 2001, and today's market capitalisation of nearly $4 billion. Shire now is
poised for a new chapter of growth.

"Shire has a strong product pipeline, a deep and capable management team, a
highly skilled R&D staff and a first-rate sales force, so we are quite
optimistic that we will have a new CEO in place early next year. In the
meantime, we will continue to execute our strategic plan," Dr. Cavanaugh said.

Revenue and earnings guidance reiterated

Shire reiterates its prior revenue and earnings guidance last provided on 1
August 2002, which is repeated below:

Full year 2002: Shire is currently likely to deliver total revenue growth in the
mid to high teens and mid to high single digit earnings growth compared to 2001.
Operating margin is still forecast to be at the upper end of Shire's stated
target range of 25-30%.

Assuming the anticipated continued success of ADDERALL XR and the potential
launch and roll out of FOSRENOL in European and US markets, subject to
regulatory approvals, as well as growth from other significant sources of
revenue, Shire continues to remain confident that it can deliver good growth in
2003.

Shire will announce its Q3 results on 6 November 2002.





Mr. Stahel, 58 years old, joined Shire in March 1994, as chief executive. Under
Mr. Stahel, the company made several strategic acquisitions, launched major new
products and dramatically enlarged Shire and positioned it in new markets.
