Business of the Annual General Meeting

The purpose of the Annual General Meeting resolutions set out above is as
follows:

Resolution 1 - Annual report and accounts
The first item of business is the requirement for shareholders to receive the
annual report and accounts for the financial year which ended on 31 December
2002.

Resolutions 2, 3 and 4 - Retirement and re-appointment of directors
In accordance with the Company's Articles of Association The Hon James Grant, Dr
Wilson Totten and Angus Russell are required to retire and, pursuant to
Resolutions 2, 3 and 4 respectively, offer themselves for re-appointment. Dr
Totten and Angus Russell are both members of the Executive Committee and James
Grant is a member of the Nomination Committee.

Resolution 5 - Retirement and appointment of directors
In accordance with the Company's Articles of Association, Matthew Emmens, having
been appointed a director of the Company during the year, is required to retire,
which he does, and offers himself for appointment. Mr Emmens was appointed to
the Board on 12 March 2003 and is the Company's Chief Executive and Chairman of
the Company's Executive Committee.

Resolution 6 - Re-appointment of auditors
This resolution is to approve the re-appointment of Deloitte & Touche as
auditors to the Company and to authorise the directors to fix their
remuneration. Deloitte & Touche were appointed on 1 August 2002 to fill a casual
vacancy following the resignation of Arthur Andersen.

Resolution 7 - Directors' Remuneration Report
This resolution is to approve the policy set out in the directors' remuneration
report, which is included in the Company's annual report and financial
statements for the financial year, which ended on 31 December 2002. This report
is prepared in accordance with the new requirements introduced by the Directors'
Remuneration Report Regulations 2002.

Resolution 8 - Authority to make market purchases
This resolution is intended to confer authority on the directors to make market
purchases of shares within a 10% limit, and in accordance with Article 39 of the
Company's Articles of Association. The authority will give the Company
flexibility in managing its balance sheet. The intention of the Board is that
purchases will only be made if they would result in an expected increase in
earnings per share, will take into account other available investment
opportunities and will be in the best interests of shareholders generally. Any
shares purchased in accordance with this authority will subsequently be
cancelled.

Options were outstanding as at 31 March 2003 to subscribe for a total number of
28,104,009 ordinary shares, or 5.8% of the Company's issued share capital. If
the authority to purchase shares is ever used in full, the proportion of issued
share capital represented by this figure would be 6.4%.

Resolution 9 - Deferred Bonus Plan
This resolution is to approve the Shire Pharmaceuticals Group plc 2003 Deferred
Bonus Plan, a summary of which is included at Appendix 1, and which allows
selected employees to invest up to 50% of their bonus or to apply such bonus in
the acquisition of ordinary shares, such shares to be matched, on a basis not
exceeding one for one, by the Company if the relevant employee remains employed
within the Group for a further three years.

Resolution 10 - Employee Benefit Trust
This resolution is to approve the Shire Pharmaceuticals Group plc Employee
Benefit Trust, ("EBT"), a summary of which is included at Appendix 2. The EBT
will be a non-UK resident trust with independent trustees, which will hold
shares on behalf of employees and ex-employees of the Group and their
dependants. The EBT will operate in conjunction with employee share plans of the
Company, including in particular the Deferred Bonus Plan.

Resolution 11 - Increase in borrowing limits
The current provision in the Company's Articles of Association allows the Board
to authorise borrowings by the Group, net, inter alia of cash, up to a ceiling
of US$400,000,000. This limit was agreed by shareholders at the AGM in July
2000. Since that time the Group has grown considerably and has become a member
of the FTSE 100. The proposed ceiling of US$1,200,000,000 is about three times
2002 EBITDA, which contrasts with the current limit which was 4.6 times 1999
EBITDA (before exceptional merger related charges). The directors consider that
the proposed limit is reasonable and is consistent with the Company's stated
strategy of growing both by acquisition and organically.

APPENDIX 1


Shire Pharmaceuticals Group plc 2003 Deferred Bonus Plan (the "Deferred Bonus
Plan")

Introduction
The Company proposes to establish the Deferred Bonus Plan in order to encourage
investment in ordinary shares by executive directors and selected senior
managers of the Group. The principal terms of the Deferred Bonus Plan may be
summarised as follows:

     Employees

1    All employees within the Group will be eligible to participate in the
     Deferred Bonus Plan. In practice, however, the intention of the
     Remuneration Committee (the "Committee") is to restrict participation to
     executive directors and senior managers.

     Operation of Deferred Bonus Plan

2    The Committee may invite eligible employees to participate by agreeing to
     apply up to 50% of their annual bonus in the acquisition of ordinary shares
     in the Company. Alternatively, participants may be invited to waive up to
     50% of their bonus and an equivalent amount will be invested into ordinary
     shares in the Company and held on the participant's behalf. In either case,
     the participant will receive a further award ("Matching Award") over a
     number of shares equivalent to the value of the gross bonus waived or
     applied in the purchase of shares ("Deferred Shares"). Selected employees
     who received a bonus in March 2003 will be invited to participate in the
     Deferred Bonus Plan in June 2003 by applying up to 50% of that bonus in the
     purchase of shares.

     Matching Awards

3    Matching Awards shall vest and the shares subject to them shall be
     transferred to the relevant participant, provided that:

     (a)  he or she remains in employment with the Group on the third
          anniversary of the grant of the Matching Award; the participant will
          be required to agree to accept liability for employers' national
          insurance contributions arising on the vesting of the Matching Awards.
          The Deferred Shares will be transferred to the participant at the same
          time as the shares subject to Matching Awards; and

     (b)  the performance criteria relating to that Award are fulfilled. The
          current intention of the Committee is to set criteria relating to the
          Company's EPS growth over the three year period exceeding the RPI.
          Matching Awards to executive directors will vest if the Company's EPS
          growth exceeds the RPI by 5%. For other participants the target will
          be 3%.

     Early vesting of matching awards

4    Matching Awards shall vest if the participant ceases to be employed within
     the Group by reason of death, disability, retirement (at normal retirement
     age), or the business or company by which he is employed being sold out of
     the Group, or in any other circumstances at the discretion of the
     Committee. However, the total number of shares that will be transferred
     following vesting will be reduced pro-rata to reflect the proportion of the
     vesting period that has expired and the extent to which performance
     criteria have been fulfilled over that period. In the event of a change of
     the control in the Control, whether by takeover, reconstruction or
     voluntary winding-up, Matching Awards will vest but be similarly pro-rated.

     Lapse of awards

5    Awards shall lapse if a participant ceases employment in circumstances
     other than those set out above, or if the participant purports to deal in
     or transfer the Deferred Shares without the permission of the Committee
     prior to the date of vesting of a Matching Award. Participants will be
     entitled to their Deferred Shares notwithstanding the lapse of Matching
     Awards.

     Individual and overall limits on Deferred Bonus Plan

6    No share shall be issued pursuant to the Deferred Bonus Plan on any date
     if, as a result, the total number of ordinary shares issued or remaining
     issuable pursuant to options granted in the previous ten years under all
     employee share option schemes, when added to the number of ordinary shares
     issued in the previous ten years pursuant to rights granted under the
     Deferred Bonus Plan and under other employee share schemes not involving
     the grant of options, would exceed 10% of the issued ordinary share capital
     of the Company on that date.

     Employee Benefit Trust

7    The Deferred Bonus Plan may be operated in conjunction with the EBT, which
     may hold Deferred Shares and shares subject to Matching Awards. The EBT may
     subscribe for shares, subject to the limits set out above, or purchase
     shares in the market in order to satisfy awards.

     Voting dividend and other rights

8    Awards shall not be transferable or assignable. Shares issued pursuant to
     the Deferred Bonus Plan shall rank pari passu with the other ordinary
     shares then in issue save in respect of dividends or other rights declared
     by reference to a record date prior to the date of issue. Participants
     shall have no voting or dividend rights in respect of shares subject to
     Matching Awards, but the Committee may request the EBT to make a cash
     payment following the vesting of a Matching Award equivalent to dividends
     paid on the shares while subject to Matching Awards. Benefits received
     under the Deferred Bonus Plan shall not be pensionable.

     Administration of Deferred Bonus Plan

9    The administration of the Deferred Bonus Plan shall be the responsibility
     of the Committee. The Board of directors may amend the Deferred Bonus Plan
     as it sees fit, provided that:

     (a)  no amendment to the detriment of holders of existing awards may be
          made without the consent of the majority of affected participants; and

     (b)  no amendment shall be made to the material advantage of participants
          without the prior approval of the Company in general meeting, except
          for amendments that are minor and to benefit the administration of the
          Deferred Bonus Plan, to take account of any changes in legislation, or
          to obtain or maintain favourable taxation, exchange control or
          regulatory treatment for the Company or any member of the Group.

     share plans, including in particular the Deferred Bonus Plan.

5    Limit on holding

     date.
