Resolution 9 Employee Stock Purchase Plan The Shire Pharmaceuticals Group plc Employee Stock Purchase Plan (the iESPPi) provides employees with an opportunity to purchase ordinary shares of the Company through accumulated payroll deductions. Currently employees whose customary employment is at least 20 hours per week are eligible to participate in the ESPP. European Directive 97/81/EC (the iDirectivei) was issued on 15 December 1997. The Directive is a framework agreement which includes the requirement to remove discrimination against part-time workers. The Directive generally provides that a part-time employee cannot be treated in a less favourable manner than a comparable full-time employee in relation to conditions of employment. As the Company has extended the ESPP to employees in certain European countries to which the Directive will apply, the Company proposes to amend the rules of the ESPP to allow all full and part-time employees to be eligible to participate in the ESPP. A copy of the rules with the proposed amendment shown will be available for inspection during normal business hours at the Companyis registered office and at the Meeting from 10.45am until the close of the Meeting. Resolution 10 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 Companyis Articles of Association. The authority will give the Company flexibility in managing its balance sheet. The Board has no immediate intention of exercising this authority. Moreover, 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 28 March 2002 to subscribe for a total number of 19,173,236 ordinary shares, or 4.0% of the Companyis 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 4.4%.
