hr hraetcl ru plc Group Pharmaceuticals Shire Shire Pharmaceuticals Group plc Annual review and summary financial statement 2001 Shire is proud of the part it plays in developing products which help people live their lives to the full. Shire, an international specialty pharmaceutical company, has a strategic focus on three therapeutic areas: central nervous system disorders, oncology and anti-infectives. It also has two platform technologies: advanced drug delivery and biologics.

Our global sales and marketing infrastructure has an established product portfolio. Shire has its own marketing subsidiaries in the US, Canada, the UK and the Republic of Ireland, France, Germany, Italy and Spain, with plans to add Japan by 2004. We cover other pharmaceutical markets indirectly through distributors. Our interests in the Pacific Rim are managed through our regional office in Singapore.

Shire has a risk-balanced R&D portfolio with clear focus on future product needs. Our global research and development expertise supported by in-licensing has, to date, successfully provided 20 marketed products, while the current pipeline of 24 projects includes 12 that are either in or post Phase II.

To enhance the potential for future growth, Shire follows two approaches, firstly, to start projects in-house through research and advanced drug delivery and secondly to in-license projects and products on reasonable commercial terms, and then to develop and launch them. This broad approach strengthens Shire’s strategy and takes account of ongoing changes that are taking place in the industry.

During the past seven years, we have completed six mergers and acquisitions and whereas we continue to evaluate M&A opportunities that offer a good strategic fit and add shareholder value, our priority is in-licensing more projects and products.

4 Shire Pharmaceuticals Group plc Chief Executive’s review

Shire is an international specialty pharmaceutical company, which products including ADDERALL XR in the US, ADEPT™ in seeks selectively to research, develop and market therapies in Europe and REMINYL in the UK*, demonstrated outstanding key areas of strategic focus. Our business model has five levels professionalism and performance. of focus: business, functional, geography, therapeutic areas and platform technologies. Geography Shire’s aim is to market its products using its own sales forces Business in eight major pharmaceutical markets of the world. In 2000 Shire has a particular interest in innovative therapies. The term we entered Spain and also set up a representative office in “specialty” refers to products prescribed by specialist doctors Singapore to manage our presence in the Pacific Rim. The only as opposed to those prescribed by primary care or general remaining market in which we do not yet operate is Japan; we practitioners. Shire targets specialist doctors who prescribe intend to build a presence there by 2004, either by launching within the following therapeutic areas: central nervous system our own products, or by acquisition. disorders, oncology and anti-infectives. Our increased geographic coverage has already increased our Shire’s strategy, as a specialty pharmaceutical group, is to target ability to attract potential licensors. The Company aims to a limited, but specific, audience and to maximise sales through capitalise on this in the future, as well as on the wider geographic a comparatively small sales force.

To reduce financial and business risk, Shire aims to maintain Platform technologies a careful and objective discipline in its approach to R&D risk Shire supports its research and development strategy with its two management by balancing its portfolio of projects towards those platform technologies: Advanced Drug Delivery and Biologics. projects viewed as low to medium risk. As part of the process we consider a number of elements, which might include the class of compound, drug target, or mode of action. We also manage the risk for in-licensed projects by looking at the current stage of development of a particular project. Rolf Stahel Chief Executive Shire’s strategy also includes the identification of products that could be enhanced using the know-how of its oral drug delivery company, Shire Laboratories Inc., based in , USA. Examples of such projects are ADDERALL XR, for the treatment of ADHD, and CARBATROL, for the treatment of epilepsy. Shire seeks to obtain patent protection through drug delivery expertise wherever possible. Another very important source of growth is our search function. This has been a key growth driver, enabling the identification of new projects, products and acquisition opportunities. Our sales and marketing function is another essential factor in our success. The Group takes pride in its well-trained and highly- motivated sales forces that have, through the rapid advancement of our main marketed products and the recent launch of four *Co-marketed by Jansen-Cilag

Bipolar disorder Patients with bipolar disorder experience alternating episodes of mania and depression. Typical symptoms of mania include rapid speech, increased energy and activity, reduced need for sleep, aggressiveness and, sometimes, hostility. Approximately 3.5 million people are affected by bipolar disorder in the US.

Based on certain evidence of the use of carbamazepine in bipolar disorder we are conducting a clinical programme with CARBATROL.

During 2001 we extended our research into Parkinson’s disease.

Compliance is a big issue for people with epilepsy. A breakthrough seizure caused by forgetting a dose can result in the loss of a driving licence. Shire’s CARBATROL makes it easier to remember by reducing the dose from three or four times a day down to twice a day, using specially formulated beads in a capsule which release the drug gradually over 12 hours. “A better quality of life”

Conversely a fall in Group Finance Director interest rates by 1% will effectively cost the Group $4.0 million. Foreign exchange market risk A number of subsidiary operations are located outside the UK. As such, the consolidated financial results are subject to fluctuations in exchange rates, particularly between the US dollar and Canadian dollar against the pound sterling. The financial statements of foreign entities are translated using the accounting policies described in note 1 to the consolidated financial statements. The exposure to foreign exchange market risk is managed by the Group’s treasury function, using forecasts provided by the operating units. There have been no significant changes to our exposure to foreign exchange risks during the year ended 31 December 2001.

Inflation Although at reduced levels in recent years, inflation continues to apply upward pressure on the cost of goods and services used by the Group. However, management believes that the net effect of inflation on the Group’s operations has been minimal during the past two years.

Euro conversion On 1 January 1999, the European Economic and Monetary Union (EMU) introduced the euro as the official currency of the 11 participating member countries. On that date, the currency exchange rates of the participating countries were fixed against

30 Shire Pharmaceuticals Group plc The remuneration report

The Company has applied the Principles of Good Governance relating to the directors’ remuneration and has complied with the provisions of the Code of Best Practice as set out below and as disclosed in the Corporate governance statements.

The Committee The Remuneration Committee (“the Committee”) comprises four non-executive directors: Dr James Cavanaugh, Dr Bernard Canavan, Mr Gérard Veilleux, and is chaired by Dr Barry Price. The Chief Executive attends meetings of the Committee at its invitation.

Remuneration policy The Committee’s policy on the remuneration of executive directors is directed at the retention and motivation of executive directors by ensuring that their remuneration is competitive with companies within the sector of specialty pharmaceutical companies, taking into account the interests of shareholders. The Committee meets regularly and acts within agreed terms of reference. In developing remuneration policy and fixing remuneration, consideration is given to salary data of directors of comparable companies of a similar size in the industry generally and, more specifically, in the specialty pharmaceuticals sector. The Chief Executive also advises the Committee on other executive remuneration and on individual performance. External agencies are also used to advise on levels of remuneration as appropriate. No director is involved in determining his own remuneration. The Committee regularly reviews the procedures and criteria for determining remuneration policy.

Annual bonuses The annual bonuses payable to executive directors are established on the basis of objectives for the Group and personal objectives. They include measurable and quantitative criteria related to financial performance. For the year ended 31 December 2001 these included revenue and earnings targets. The maximum annual bonus for each executive director for the year ended 31 December 2001 was 55% of salary in respect of Mr Rolf Stahel and 50% in respect of Mr Angus Russell and Dr Wilson Totten.

Share options Details of the share option schemes are set out below and in note 26 to the consolidated financial statements. Except as mentioned below, none of the executive directors who served during the year were granted additional options under any of the Company’s share option schemes in the year ended 31 December 2001. Share options under the Sharesave Scheme (see note 26 on pages 65 to 67) are offered at a discount as permitted by paragraph 13.31 of the Listing Rules. Share options are not otherwise offered at a discount. The following share options were granted to executive directors during the year:

Number of Exercise price Executive director Share option scheme Date of grant ordinary shares £ Mr Rolf Stahel 2000 Executive Scheme B 05.06.01 126,492 12.57 Sharesave Scheme 01.12.01 1,151 8.41 Dr Wilson Totten 2000 Executive Scheme B 05.06.01 73,986 12.57 Mr Angus Russell 2000 Executive Scheme B 05.06.01 69,213 12.57

Share options are granted to executive directors and senior executives as an incentive. The grant of options is wholly discretionary. In granting share options, the Committee takes into account the advice and recommendations of the Chief Executive and individual salary levels and positions within the Group. On 4 March 2002 the executive directors were granted share options under the 2000 Executive Scheme at a price of £5.065 per share. Mr Rolf Stahel, Mr Angus Russell and Dr Wilson Totten were granted 209,211, 114,474 and 122,368 options respectively.

Retirement benefits The Company contributes 10% of salary to the personal pension plans of the executive directors.

Fees for non-executive directors The Board determines the remuneration of each of the non-executive directors. Except as detailed on page 35, non-executive directors do not participate in any of the Company share schemes or other employee benefit schemes. Certain non-executive directors hold share options relating to their service with companies that have been acquired or merged with Shire whose policy was to grant share options. No options have been granted to non-executive directors in their capacity as non-executive directors of Shire.

Shire Pharmaceuticals Group plc 31 The remuneration report

Notes i) These options have been granted over shares in Shire Holdings Limited, a previous holding company of the Group. Exercise of these options results in the optionholder receiving ordinary shares in the Company. ii) Options granted under the Executive Scheme are subject to performance criteria and cannot be exercised in full, unless the Company’s share price increases at a compound rate of at least 20.5% per annum over a minimum three-year measurement period. If the Company’s share price increases at a compound rate of 14.5% per annum over a minimum three-year measurement period, 60% of the options may be exercised. If these conditions are not met after the initial three years, they are thereafter tested quarterly by reference to share price growth over the extended period. If the share price does not meet these conditions at any time, none of the options will become exercisable. iii) Options granted under the Sharesave Scheme are granted with an exercise price equal to 80% of the mid-market price on the day before invitations are issued to employees. Following changes in the Inland Revenue rules governing such schemes, employees may now enter into three or five-year savings contracts. iv) These options have been granted over shares in SLI, formerly Pharmavene Inc., a company acquired by the Group on 23 March 1997. Exercise of these options results in the optionholder receiving ordinary shares in the Company. As a result of the acquisition of SLI, and in accordance with the terms of the original share option plan, all options granted under that plan became immediately capable of exercise. v) These options have been granted over shares in SRI, formerly Richwood Pharmaceutical Company, Inc., a company acquired by the Group on 22 August 1997. Exercise of these options results in the optionholder receiving ordinary shares in the Company. As a result of the acquisition of SRI, and in accordance with the terms of the original share option plan, all options granted under that plan became immediately capable of exercise. vi) These options have been granted over shares in Roberts Pharmaceutical Corporation, a company acquired by the Group on 23 December 1999. Exercise of these options results in the optionholder receiving ordinary shares in the Company. As a result of the acquisition of Roberts, and in accordance with the terms of the original Roberts share option plan, all options granted under that plan became immediately capable of performance. vii) Options granted under the 2000 Executive Scheme are subject to criteria and cannot be exercised in full, unless the Company’s share price increases at a compound rate of at least 20.5% per annum over a minimum three-year period. If the Company’s share price increases at a compound rate of at least 14.5% per annum over a minimum three-year measurement period, 60% of the options will be exercisable. If these conditions are not met after the initial three-year measurement period, they will thereafter be tested quarterly by reference to compound annual share price growth over an extended period. If the share price does not meet these conditions at any time, none of these options will become exercisable. At the Annual General Meeting of the Company held on 5 June 2001, a resolution was passed to permit the grant of options under the 2000 Executive Scheme to be made subject to performance criteria determined prior to the date of grant. Subsequent to the passing of this resolution options have been granted based on a performance criteria being satisfied before grant namely that the Company’s share price had increased by an annualised compound rate of 20.5% over a minimum three-year period. viii) Following the merger with BioChem Pharma Inc. on 11 May 2001, the BioChem Stock Option Plan was amended such that options over BioChem’s common stock became options over ordinary shares of the Company. All BioChem options, which were not already exercisable, vested and became exercisable as a result of the merger. It is intended that no further options will be granted under the BioChem Stock Option Plan. ix) Under the Stock Purchase Plan options are granted with an exercise price equal to 85% of the fair market value of a share on the enrolment date (the first day of the offering period) or the exercise date (the last day of the offering period), whichever is lower. The offering period is for 27 months.

Shire Pharmaceuticals Group plc 37 Corporate governance statements

The Company is committed to high standards of corporate governance The Combined Code on Corporate Governance appended to the Listing Rules of the Financial Services Authority requires companies listed on the London Stock Exchange to make a disclosure statement on its application of the principles of and compliance with the provisions of good governance set out in the Combined Code. Throughout the period under review the Company has been committed to high standards of corporate governance, has always sought to comply fully with the provisions of the Combined Code and has, in the directors’ opinion, done so.

The Board The Board meets at least four times a year and comprises three executive and seven non-executive directors and the meetings are well attended. The Board seeks to provide effective leadership and control required for a listed company and in so doing has formally reserved specific matters to itself for determination. Specific powers and authorities are also delegated to an Executive Committee and to various other Board committees set out below. Four of the non-executive directors (Dr Barry Price, Dr Bernard Canavan, Mr Ronald Nordmann and Mr Gérard Veilleux) are viewed as independent of management and free from any business or other relationship which could materially interfere with the exercise of their independent judgement. Whilst the Company views Dr James Cavanaugh, Dr Francesco Bellini and the Hon James Andrews Grant as independent non- executive directors, the Company does accept that on a strict interpretation of the Combined Code the interests that Dr Cavanaugh has as President of HealthCare Ventures LLC and the position The Hon James Andrews Grant has as a partner of Stikeman Elliot, a law firm retained by BioChem Pharma Inc. prior to the merger, prevents the strict application of independence. The same is also relevant to Dr Francesco Bellini by virtue of the executive directorship that Dr Bellini held with BioChem Pharma Inc. All directors have access to the advice and guidance of the Company Secretary and are encouraged to seek independent advice at the Company’s expense, where they feel it is appropriate. No such independent advice has as yet been sought. The Board is confident that all its members have the knowledge, aptitude and experience to perform the functions required of a director of a listed company. Biographical details of the Board are shown on pages 28 to 29.

Chairman and Chief Executive The offices of Chairman and Chief Executive are held separately. The non-executive Chairman, Dr James Cavanaugh, is responsible for the conduct of the Board and ensures that Board discussions are conducted in such a way that all views are taken into account, so that no individual director or small group of directors dominates proceedings. The Chief Executive, Mr Rolf Stahel, is responsible for running the business and chairs the Executive Committee.

Senior and non-executive director Dr Barry Price is the nominated senior independent non-executive director.

Supply of information The executive directors and the Company Secretary are responsible for ensuring that detailed information is provided to the Board at least one week before any scheduled meeting of the Board. Before decisions are made, consideration is given to the adequacy of information available to the Board and, if necessary, decisions are deferred if further information is required.

Re-appointment Non-executive directors are appointed for a maximum period of two years. Re-appointment of non-executive directors following the expiry of such two-year period is subject to Board approval.

Committees of the Board The standing Board committees are the Audit Committee, the Remuneration Committee, the Nomination Committee and the Executive Committee. Each committee has its own written terms of reference that have been approved by the Board. Details of each committee are as follows: i) The Audit Committee is chaired by Dr Bernard Canavan and usually meets on four occasions in the year. Other members of the Committee are Dr James Cavanaugh, Dr Barry Price and Mr Ronald Nordmann. Under its terms of reference the Committee is required, among other things, to review the scope and extent of the internal operational audit programme, to monitor the relationship with external auditors, to review the Company’s statutory accounts and other financial statements and information, to monitor compliance with statutory and listing requirements for any exchange on which the Company’s shares are quoted, to review the business risks faced by the Company and to initiate special projects or investigation as it sees fit. ii) The Remuneration Committee, under the chairmanship of Dr Barry Price, usually meets three times a year. Dr James Cavanaugh, Dr Bernard Canavan and Mr Gérard Veilleux are the other members of this Committee. The remuneration of non-executive directors is determined by the Chief Executive together with the executive directors. The remuneration report appears on pages 31 to 37 and provides further information on this committee. iii) The Nomination Committee has been delegated with responsibility for nominations to the Board. This Committee meets as required and is chaired by Dr James Cavanaugh. Mr Rolf Stahel and Mr Ronald Nordman also serve on this Committee. The Committee provides a formal and transparent procedure for the appointment of new directors to the Board. iv) The Executive Committee has had the day-to-day management of the Company delegated to it by the Board and operates within clear and formal parameters. Mr Rolf Stahel is the Chairman of the Committee, which consists of nine senior executives including the three executive directors. The Executive Committee reports to, and seeks guidance from, the Board on a regular basis.

38 Shire Pharmaceuticals Group plc Directors’ remuneration The Company’s remuneration policy appears on page 31. The policy details the level of remuneration for directors and the basis upon which executive remuneration is fixed.

Relations with shareholders The Company is committed to maintaining good relations with shareholders through the provision of regular interim and annual reports and other trading statements. The Company also arranges individual and group meetings with its institutional shareholders in order to discuss relevant communications to ensure that the investing community receives a balanced and complete view of the Company’s performance and issues faced by the business. The Company holds its Annual General Meeting in London and all shareholders are given the opportunity to ask questions of the Board. The Company’s website at www.shire.com provides Company information and is regularly updated.

Balanced and understandable assessment of positions and prospects The Company strives to give full, timely and realistic assessments of matters that impact on its business and financial position and to present scientific and other price-sensitive data in a balanced way. The Company voluntarily adopted quarterly financial reporting, which is not obligatory in the UK, and before it was required under SEC rules.

Financial reporting The Board has ultimate responsibility for the preparation of accounts and for the monitoring of systems of internal financial control. The Board strives to present a balanced and understandable assessment of the Company’s position and its prospects and endeavours to present scientific and other price-sensitive information in a balanced way. The Company publishes quarterly financial reports so that its shareholders can monitor the Company’s financial position regularly. On behalf of the Board, the Audit Committee examines the effectiveness of systems of internal financial control on a regular basis. This includes considering independent access to the Auditors throughout the year in addition to presentations from the Auditors on a quarterly basis. Any significant findings or identified risks are closely examined and are reported to the Board with recommendations for action.

Internal control In applying the principle that the Board should maintain a sound system of internal control to safeguard shareholders’ investment and the Company’s assets, the directors recognise that they have overall responsibility for the Company’s system of internal control and for reviewing its effectiveness. The directors believe that the Company has applied this principle during the year under review. However, there are limitations in any system of internal control and accordingly even the most effective system can provide only reasonable and not absolute assurance. Such a system is designed to manage rather than eliminate the risk of failure to achieve business objectives and can provide only reasonable and not absolute assurance against material misstatement or loss. The Company has an ongoing process for identifying, evaluating and managing the significant risks that it faces. This process has been in operation throughout the period under review. In particular, the Executive Committee, the Audit Committee and the Board have reviewed the schedule of risks faced by the Company. This includes analysis of the impact of the operation of key risks and the action being taken to avoid or reduce each risk. In particular, the schedule of risks allocates responsibility for management of each key risk to senior executives. These reviews, together with regular reports on financial performance, represent the main elements in establishing the effectiveness of the system of internal control. In addition, the Company has a system of control procedures and compliance with these procedures is monitored through a system of internal review. Any significant issues arising are reported to the Board for review. During the year, the Audit Committee has considered how it can obtain assurance that risks continue to be managed effectively following the increase in the extent of operations worldwide. In November, proposals were agreed by the Audit Committee for the establishment of an outsourced risk assurance and internal audit function. This service will not be provided by the Auditors, Arthur Andersen, and will commence in 2002.

Audit Committee and auditors The Board has, through the Audit Committee, established formal and transparent arrangements for financial reporting, internal control and external auditing. All employees can raise any concerns in these areas with the Chairman of the Audit Committee in the strictest confidence. The Audit Committee’s terms of reference have been extended to cover the Group’s risk management activities as a whole and not just the financial aspects of internal control. The Audit Committee reviews the scope and results of the audit and non-audit services, the cost effectiveness and the independence and objectivity of the auditors.

Shire in the community The Company recognises that business activities have an influence on the community and accepts that it has a duty to carry these out in a responsible manner. The continual ongoing development and implementation of the Company’s environmental policy reflects the key activities of the Company at each of its office sites, production sites and suppliers’ sites. This has enabled the Company to measure its performance now and in the future. The Company’s commitment to the community has already led to the Company’s inclusion in the FTSE4Good index.

Shire Pharmaceuticals Group plc 39 Statement of directors’ responsibilities

Accounts and adoption of going concern basis Company law requires the directors to prepare accounts for each financial year which give a true and fair view of the state of affairs of the Company and Group and of the profit or loss of the Group for that period. After making enquiries, the directors have a reasonable expectation that the Company and the Group have adequate resources to continue in operational existence in the foreseeable future. For this reason, they continue to adopt the going concern basis in preparing the accounts. In preparing the accounts, the directors are required to select suitable accounting policies and then apply them consistently; make judgements and estimates that are reasonable and prudent; and state whether applicable accounting standards have been followed, subject to any material departures disclosed and explained in the accounts.

Other matters The directors have responsibility for ensuring that the Company keeps accounting records which disclose with reasonable accuracy the financial position of the Company and Group and which enable them to ensure that the financial statements comply with the Companies Act 1985. They are also responsible for safeguarding the assets of the Company and Group and for preventing and detecting fraud and other irregularities. The directors, having prepared the accounts, are required to provide to the auditors such information and explanation as the auditors think necessary for the performance of their duty.

Report of Independent Public Auditors To the shareholders of Shire Pharmaceuticals Group plc

We have audited the accompanying consolidated balance sheets of Shire Pharmaceuticals Group plc and its subsidiaries as of 31 December 2001 and 2000, and the related consolidated statements of operations, comprehensive income, changes in shareholders’ equity, and cash flows for the years ended 31 December 2001, 2000 and 1999. These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements based on our audits. We did not audit the financial statements for the years ended 31 December 2000 and 1999 of BioChem Pharma Inc., a company acquired in 2001 in a transaction accounted for as a pooling of interests. Such statements are included in the consolidated financial statements of Shire Pharmaceuticals Group plc and reflect total assets of 35% and 34%, and total revenues of 23% and 25% respectively, of the related consolidated totals for the years ended 31 December 2000 and 1999, after restatement to reflect certain adjustments as set forth in note 3. The financial statements prior to those adjustments were audited by other auditors whose report has been furnished to us, and our opinion, insofar as it relates to amounts included for BioChem Pharma Inc., for the years ended 31 December 2000 and 1999, is based solely upon the report of the other auditors. We conducted our audits in accordance with auditing standards generally accepted in the United States. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits and the report of the other auditors provide a reasonable basis for our opinion. In our opinion, based on our audit and the report of the other auditors, the financial statements referred to above present fairly, in all material respects, the financial position of Shire Pharmaceuticals Group plc and subsidiaries as of 31 December 2001 and 2000, and the results of their operations and their cash flows for the years ended 31 December 2001, 2000 and 1999 in conformity with accounting principles generally accepted in the United States.

Shire Pharmaceuticals Group plc 45 Notes to the financial statements

1 Summary of significant accounting policies a) Description of operations and principles of consolidation Shire Pharmaceuticals Group plc (the Company) is an international specialty pharmaceutical company with a strategic focus on three therapeutic areas: central nervous system disorders, oncology and anti-infectives. The Company’s strategy is further supported by two technology platforms, drug delivery and biologics. The Company has sales and marketing subsidiaries with a portfolio of products targeting the US, Canada, UK, Republic of Ireland, France, Germany, Italy and Spain. Shire also covers other significant pharmaceutical markets indirectly through distributors. The business is operated and managed within three individual operating segments: US, International and global research and development. Within these segments, revenues are derived primarily from three sources: sales of products by the Company’s own sales and marketing operations, royalties and licensing and development fees. The Company is referred to as “specialty” because its principal products tend to be prescribed by specialists as opposed to primary care physicians. The Company’s main approach is to start projects in-house through research and advanced drug delivery, or to in-license projects and then to develop and launch them using its sales and marketing capability in eight of the key world markets. The Company seeks to protect the intellectual property upon which it relies through a range of patents and patent applications (both its own and those of its licensors). The Company’s principal products include: in the US, ADDERALL XR and ADDERALL for the treatment of ADHD; AGRYLIN for the treatment of elevated blood platelets; PENTASA for the treatment of ulcerative colitis; CARBATROL for the treatment of epilepsy; and PROAMATINE for the treatment of postural hypotension. In addition, the Company receives royalties on sales of REMINYL for the treatment of Alzheimer’s disease, marketed by Johnson & Johnson, and on EPIVIR, COMBIVIR and TRIZIVIR for the treatment of HIV/AIDS and EPIVIR-HBV™ for the treatment of hepatitis B, each marketed by GSK; in the UK, the CALCICHEW range, used primarily as adjuncts in the treatment of osteoporosis, and REMINYL, which was launched in September 2000 and is co-promoted by Janssen-Cilag; in Canada, 3TC for the treatment of HIV/AIDS, COMBIVIR and HEPTOVIR™ (marketed in partnership with GSK); AMATINE; SECOND LOOK™, a breast cancer diagnostics product for which the Company also received a US FDA approval in January 2002; and FLUVIRAL S/F, a vaccine for the prevention of influenza; and in the rest of the world, the Company receives royalties on the sales of ZEFFIX for the treatment of hepatitis B, marketed by GSK, and will receive royalties on sales of REMINYL from Janssen Pharmaceutica. In addition, the Company has a number of products in late stage development including DIRAME for the treatment of analgesia, FOZNOL for the treatment of high blood phosphate levels associated with kidney failure and TROXATYL for the treatment of leukaemia and pancreatic cancer. The Company submitted the first regulatory submission for FOZNOL under the European Mutual Recognition procedure on 13 March 2001. The accompanying consolidated financial statements include the accounts of Shire Pharmaceuticals Group plc and all its subsidiary undertakings after elimination of intercompany accounts and transactions. b) Use of estimates in financial statements The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Estimates and assumptions are primarily made in relation to provisions for product returns, litigation and sales deductions. c) Revenue recognition The Company recognises revenue when: there is persuasive evidence of an arrangement; delivery of products has occurred or services have been rendered; the seller’s price to the buyer is fixed or determinable; and collectibility is reasonably assured. The Company’s principal revenue streams and their respective accounting treatments are discussed below: i) Product sales Revenue for the sales of products is recognised as net revenue upon shipment to customers. Provisions for certain rebates, product returns and discounts to customers are provided for as reductions to net revenue in the same period as the related sales are recorded. Approximately $17.0 million of ADDERALL XR product launch shipments made in Q4 2001 will not be recognised as product revenue until 2002, in accordance with Staff Accounting Bulletin 101, as these sales had not been realised and earned at 31 December 2001. ii) Licensing and development fees Licensing and development fees represent revenues derived from licence agreements and from collaborative research and development arrangements.

46 Shire Pharmaceuticals Group plc 1 Summary of significant accounting policies continued Initial licence fees are not considered to be separable from the associated research and development activities, even where such fees are non-refundable and not creditable against research and development services to be rendered. Initial licence fees are thus deferred and recognised over the period of the licence term or the period of the associated research and development agreement. In circumstances where initial licence fees are not for a defined period, revenues are deferred and recognised over the period to the expiration of the relevant patent to which the licence relates. During the term of certain research and development agreements, the Company receives non-refundable milestones as certain technical targets are achieved. Revenues are recognised on achievement of milestones. The Company also receives non-refundable clinical milestones when certain targets are achieved during the clinical phases of development, such as the submission of clinical data to a regulatory authority. These clinical milestones are recognised when received. If milestone payments are creditable against future royalty payments, the milestones are deferred and released over the period in which the royalties are anticipated to be paid. iii) Royalty income Royalty income relating to licenced technology is recognised when receivable. Where applicable, all revenues are stated net of value added tax and similar taxes, trade discounts and intercompany transactions. No revenue is recognised for consideration, the value or receipt of which is dependent on future events, future performance or refund obligations. d) Research and development Research and development expenditures include funded and unfunded expenditures and are charged to operations in the period in which the expense is incurred. Milestones payable in respect of research and development work are charged to the income statement on achievement of those milestones. e) Leased assets The costs of operating leases are charged to operations on a straight-line basis over the lease term, even if rental payments are not made on such a basis. Assets acquired under capital leases are included in the balance sheet as tangible fixed assets and are depreciated over the shorter of the period of the lease or their useful lives. The capital elements of future lease payments are recorded as liabilities, while the interest elements are charged to the income statement over the period of the leases to produce a level yield on the balance of the capital lease obligation. f) Pensions The Group contributes to personal defined contribution pension plans of employees. Contributions are charged to the income statement as they become payable. These contributions are detailed in note 24. Details of the supplemental Executive Retirement Plan operated by the Group are given in note 24. g) Finance costs of debt Finance costs of debt are recorded as a deferred asset and then amortised to the income statement over the term of the debt using the level yield method. Deferred financing costs relating to debt extinguishments are written off to the income statement in that period. h) Income taxes The Company provides for income taxes in accordance with SFAS No.109, “Accounting for Income Taxes”. Deferred tax assets and liabilities are provided for differences between the financial statement and tax bases of assets and liabilities that will result in future taxable or deductible amounts. The deferred tax assets and liabilities are measured using the enacted tax laws and rates applicable to the periods in which the differences are expected to affect taxable income. Income tax expense is computed as the tax payable or refundable for the period plus or minus the change during the period in deferred tax assets and liabilities. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion or all of the deferred tax assets will not be realised. i) Advertising expense The Company expenses the cost of advertising as incurred. Advertising costs amounted to $21.8 million, $6.6 million and $6.7 million for the years ended 31 December 2001, 2000 and 1999 respectively. j) Foreign currency Monetary assets and liabilities in foreign currencies are translated into US dollars at the rate of exchange ruling at the balance sheet date. Transactions in foreign currencies are translated into US dollars at the rate of exchange ruling at the date of the transaction. Transaction gains and losses are recognised in arriving at operating income. The functional currency of each of the Company’s subsidiaries is the local currency. The results of overseas operations, whose functional currencies are not US dollars, are translated at the average rates of exchange during the period and their balance sheets at the rates ruling at the balance sheet date. The cumulative effect of exchange rate movements is included in a separate component of other comprehensive income.

Shire Pharmaceuticals Group plc 47 Notes to the financial statements

1 Summary of significant accounting policies continued The consolidated financial statements are prepared from records maintained in the country in which the subsidiary is located and are translated into US dollars according to the above policy. Foreign currency exchange transaction gains and losses on an after-tax basis included in consolidated net income in the years ended 31 December 2001, 2000, and 1999, pursuant to SFAS No. 52, “Foreign Currency Translation”, amounted to a $0.5 million loss, $2.1 million gain and $1.3 million gain, respectively. k) Employee stock plans The Company accounts for stock options in accordance with the provisions of APB Opinion No. 25, “Accounting for Stock Issued to Employees”, and related interpretations. l) Cash and cash equivalents Cash and cash equivalents include cash in banks and bank short-term investments with original maturities of less than 90 days. m) Marketable securities and other current asset investments Marketable securities classified as available for sale consist primarily of debt instruments with maturities of more than three months. They are marked to market at each balance sheet date, with gains and losses recorded in a separate component of other comprehensive income. Other than temporary impairments in value are recorded through the income statement. n) Inventories Inventories, consisting primarily of finished goods, are stated at the lower of cost or net realisable value. Cost incurred in bringing each product to its present location and condition is based on purchase costs calculated on a first-in, first-out basis, including transport. Net realisable value is based on estimated normal selling price less further costs expected to be incurred to completion and disposal. Provision is made for obsolete, slow moving or defective items where appropriate. o) Investments The Company accounts for its investments in 20% to 50% owned companies using the equity method of accounting. Accordingly, the Company’s share of the earnings of these companies is included in “Other income, net”. The related equity investment is included in “Investments”. At 31 December 2001, the GlaxoSmithKline joint venture in Canada was the Company’s only such equity investment. Investments which are accounted for under the cost method are stated at cost, less provisions for other than temporary impairment in value. Impairment is assessed by reference to the fair value of the securities as determined using established financial methodologies. Investments in equities with readily determinable market values are marked to market. The fair value of debt investments in private entities and non-traded securities of public entities are measured by valuation methodologies including discounted cash flows. p) Intangible assets Intangible assets comprise goodwill and intellectual property rights. Goodwill arising on the acquisition of subsidiary undertakings and businesses, representing any excess of the fair value of the consideration given over the fair value of the identifiable assets and liabilities acquired, is capitalised and written off on a straight-line basis over its useful economic life. Goodwill recognised in each significant business combination is being amortised over a period of five to 30 years on a straight-line basis depending on the nature of the goodwill, and is evaluated periodically for realisability based on expectations of undiscounted cash flows and earnings from operations for each subsidiary having a material goodwill balance. The following factors are considered in estimating the useful lives. Where an intangible asset is a composite of a number of factors, the period of amortisation is determined from considering these factors together: regulatory and legal provisions, including the regulatory approval and review process, patent issues and actions by government agencies; the effects of obsolescence, changes in demand, competing products and other economic factors, including the development of competing drugs that are more effective clinically or economically; and actions of competitors, suppliers, regulatory agencies or others that may eliminate current competitive advantages. Impairments of goodwill are recognised if expected undiscounted cash flows are not sufficient to recover the goodwill. If a material impairment is identified, goodwill is written down to its estimated fair value. Fair value is determined based on the present value of expected net cash flows to be generated by the business, discounted using a rate commensurate with the risks involved. Intellectual property, including trademarks for products with an immediate defined revenue stream and acquired for valued consideration, is recorded at cost and amortised in equal annual instalments over the estimated useful life of the related product which range from five to 40 years. Intellectual property with no defined revenue stream where the related product has not yet completed the necessary approval process is written off on acquisition. Amounts recorded as intangible assets are reviewed for impairment on a periodic basis using expected undiscounted cash flows. Continuing milestone payments on intellectual property with no defined revenue stream are charged to operations. Royalty payments due on sales of products are charged to operations when a liability has been incurred.

48 Shire Pharmaceuticals Group plc 1 Summary of significant accounting policies continued q) Property, plant and equipment Property, plant and equipment is shown at cost less accumulated depreciation and any provision for impairment. Depreciation is provided on a straight-line basis at rates calculated to write off the cost less estimated residual value of each asset over its estimated useful life as follows: Buildings 20 to 50 years Office furniture, fittings and equipment 4 to 10 years Warehouse, laboratory and manufacturing equipment 4 to 10 years

The cost of land is not depreciated. Expenditures for maintenance and repairs are charged to expense as incurred; costs of major renewals and improvements are capitalised. At the time property, plant and equipment is retired or otherwise disposed of, the cost and accumulated depreciation are eliminated from the asset and accumulated depreciation accounts and the profit or loss on such disposition is reflected in income. r) Concentration of credit risk Revenues are mainly derived from agreements with major pharmaceutical companies and relationships with pharmaceutical wholesale distributors and retail pharmacy chains. Significant customers are disclosed in note 22. Such clients have significant cash resources and therefore any credit risk associated with these transactions is considered minimal. Excess cash is invested in bank and building society term deposits and commercial paper from a variety of companies with strong credit ratings. These investments typically bear minimal credit risk. s) Related parties Management believes that transactions with related parties are conducted on the same basis as they would have been with unrelated parties. t) New accounting pronouncements In June 2001, the FASB issued SFAS No. 141, “Business Combinations”, and SFAS No. 142, “Goodwill and Other Intangible Assets”. SFAS No. 141 requires the use of the purchase method of accounting for all business combinations initiated after 30 June 2001. Had the BioChem transaction been initiated after this date, it would have been required to be accounted for under the purchase method rather than the pooling of interests method. SFAS No. 141 requires intangible assets to be recognised if they arise from contractual or legal rights or are “separable”, ie, it is feasible that they may be sold, transferred, licenced, rented, exchanged or pledged. As a result, it is likely that more intangibles will be recognised under SFAS No. 141 than its predecessor, APB Opinion No. 16, although in some instances previously recognised intangibles will be subsumed into goodwill. SFAS No. 142 is effective for fiscal years beginning after 15 December 2001 although goodwill on business combinations consummated after 1 July 2001 will not be amortised. On adoption the Company may need to record a cumulative effect adjustment to reflect the impairment of previously recognised intangible assets. In addition, goodwill recognised on prior business combinations will cease to be amortised. Had the Company adopted SFAS No. 142 at 1 January 2001 the Company would not have recorded a goodwill amortisation charge of $10.8 million for the year ended 31 December 2001. The Company has not determined the impact that these Statements will have on intangible assets or whether a cumulative effect adjustment will be required upon adoption. In June 2001, the FASB issued SFAS No. 143, “Accounting for Asset Retirement Obligations”. SFAS No. 143 requires the fair value of a liability for asset retirement obligations to be recognised in the period in which it is incurred if a reasonable estimate of the fair value can be made. The associated asset retirement costs are capitalised as part of the carrying amount of the related long-lived asset. SFAS No. 143 is effective for financial statements issued for fiscal years beginning after 15 June 2002. The Company does not believe the adoption of this Statement would have a material impact on its results of operations or financial position. In August 2001, the FASB issued SFAS No. 144, “Accounting for the Impairment or Disposal of Long-Lived Assets”. SFAS No. 144 establishes a single accounting model for long-lived assets to be disposed of by sale consistent with the fundamental provisions of SFAS No. 121, “Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to be Disposed of”. While it supersedes APB Opinion No. 30, “Reporting the Results of Operations – Reporting the Effects of Disposal of a Segment of a Business, and Extraordinary, Unusual and Infrequently Occurring Events and Transactions”, it retains the presentation of discontinued operations but broadens that presentation to include a component of an entity (rather than a segment of a business). However, discontinued operations are no longer recorded at net realisable value and future operating losses are no longer recognised before they occur. Under SFAS No. 144 there is no longer a requirement to allocate goodwill to long-lived assets to be tested for impairment. It also establishes a probability-weighted cash flow estimation approach to deal with situations in which there are a range of cash flows that may be generated by the asset being tested for impairment. SFAS No. 144 also establishes criteria for determining when an asset should be treated as held for sale. SFAS No. 144 is effective for fiscal years beginning after 15 December 2001 and interim periods within those fiscal years, with early application encouraged. The provisions of the Statement are generally to be applied prospectively. The Company is currently assessing whether the adoption of SFAS No. 144 will have any impact on its results of operations or financial position. u) Statutory accounts The consolidated financial statements for the years ended 31 December 2001, 2000 and 1999 do not comprise statutory accounts within the meaning of Section 240 of the UK Companies Act 1985. Statutory accounts for the years ended 31 December 2000 and 1999 have been delivered to the Registrar of Companies for England and Wales. The auditors’ report on those accounts was unqualified. Shire Pharmaceuticals Group plc 49 Notes to the financial statements

2 Business combinations and reorganisations Year ended 31 December 2001 a) BioChem merger On 11 May 2001, the Company acquired 100% of the outstanding stock of BioChem Pharma Inc. (BioChem), an international specialty pharmaceutical company based in Laval, Canada. The merger was achieved through an exchange of shares. The Company issued 179,447,629 ordinary shares and 17,292,148 exchangeable shares in order to effect the business combination. This transaction was accounted for by the pooling of interests method in accordance with APB Opinion No. 16, “Accounting for Business Combinations”. Consequently, the consolidated financial statements give retroactive effect to the merger. Details of the results of operations of BioChem for the period before the merger was consummated, which is the period from 1 January 2001 to 11 May 2001, that are included in the combined net income of the Company are as follows: $000 Revenue 51,592 Net income 23,003 Other changes in stock holders’ equity: Issue of common shares on exercise of stock options 2,170

The revenues and earnings previously reported by the Company for the years ended 31 December 2000 and 1999 can be reconciled to the combined amounts presented herein as follows: 2000 2000 1999 1999 Revenue Net income Revenue Net income $000 $000 $000 $000 As previously reported 517,608 76,171 401,532 (94,998) BioChem pooled results 198,478 174,346 185,694 93,098 Accounting policy alignment (see note 3) (44,976) (38,790) (49,973) (45,532) As restated 671,110 211,727 537,253 (47,432) b) Dispositions During 2001, the Company recorded a $8.1 million loss on the sale of its manufacturing facility in Toronto, Canada. As a result of the merger with BioChem, the decision was made to close the Toronto facility and to eliminate duplicate positions across the combined organisation. The Company’s existing Canada-based sales and marketing operations in Toronto have been combined with those of BioChem in Laval. During the third quarter of 2001, the Company disposed of certain non-strategic products for net proceeds of approximately $4.5 million. A loss on disposition of $2.0 million was recorded. Year ended 31 December 2000 a) Divestiture of a subsidiary In March 2000, BioChem concluded the divestiture of its diagnostics operations to a management-led group of this subsidiary. The diagnostic operations were previously accounted for as discontinued operations following the adoption of a formal plan of disposal on 29 January 1999. As consideration, BioChem received a debenture in the amount of $35.8 million to be paid out of future cash flows. For accounting purposes, the transaction was not recorded as a sale since certain significant risks of ownership were not transferred to the buyer. Accordingly, as at 31 December 2000, the net assets transferred to the buyer are presented in the non-current asset section of the balance sheet as “Net assets of business transferred under contractual arrangements”. As at 31 December 2000, the Company had guaranteed the reimbursement of a long-term debt of this company amounting to 37.3 billion Italian lira ($18.1 million). Summarised data relating to the discontinued operations of the diagnostics operations of BioChem for the year ended 31 December 1999 and net asset data for 1999 are as follows: 1999 $000 Loss from operations of diagnostics segment (less applicable income taxes of $948 in 1999) (738) Loss on disposal of diagnostics segment, including provision of $11,441 for operating losses during phase-out period (less applicable income taxes of nil) (11,441) Net loss (12,179) Net assets of discontinued operations Current assets 62,094 Property, plant and equipment 10,174 Other assets 13,382 Current liabilities (29,487) Long-term liabilities (24,088) 32,075

50 Shire Pharmaceuticals Group plc 2 Business combinations and reorganisations continued b) CliniChem Development Inc. CliniChem Development Inc. (CliniChem) was formed by BioChem to conduct research and development of certain of BioChem’s human therapeutic and vaccine product candidates. On 8 June 1998, BioChem made a $101.3 million cash contribution to CliniChem’s capital. Simultaneously, BioChem concluded a series of agreements with CliniChem. BioChem granted to CliniChem an exclusive perpetual licence to use BioChem technology to conduct the CliniChem programmes and related activities and to manufacture and commercialise the CliniChem products worldwide. CliniChem paid a fee to BioChem in exchange for the technology licences. The technology fee was payable monthly at a rate of $0.2 million per month over a period of 48 months. During 1998 BioChem spun off to its shareholders its investment in CliniChem. In connection with this spin off, BioChem retained rights in CliniChem including that BioChem had an option to reacquire all shares in CliniChem at any time. As a result, CliniChem was fully consolidated into the Company’s accounts even though the investment had been spun off to its shareholders, with the inter- company transactions eliminated, as BioChem still retained control of this company. On 15 December 2000, BioChem reacquired the shares in CliniChem for $32.5 million. This additional consideration was allocated to the net assets at that date as follows: $000 Other assets 5,560 Acquired in-process research and development charged to earnings 26,947 32,507

As a result of the transaction, the Company incurred a charge for the year ended 31 December 2000 representing the acquisition of in-process research and development in accordance with SFAS No. 2. The acquired in-process research and development charge of $26.9 million represents the value of CliniChem’s products in development at the date of the additional investment in CliniChem. Technological feasibility of these products was not established at this date. These products were considered to have no alternative future use other than the therapeutic indications for which they were in development. The work remaining to complete the development involved continuing formulation activity, clinical studies and the submission of regulatory filings to seek marketing approval. As pharmaceutical products cannot be marketed without regulatory approvals, the Company will not receive any benefit unless it receives such regulatory approvals. See note 3 for a discussion of the realignment of BioChem’s accounting policies in respect of CliniChem to conform with those of the Company.

3 Accounting policy alignment – consolidation of CliniChem In 1998, BioChem spun off to its shareholders its investments in CliniChem. In connection with this spin-off, BioChem retained rights in CliniChem, including the option to reacquire all shares in CliniChem at any time. Under EITF 99-16, this transaction would result in CliniChem continuing to be consolidated by BioChem, as BioChem would have significant continuing involvement in the operation of CliniChem. However, at the time that CliniChem was spun off, EITF 99-16 had not been issued and BioChem elected to de-consolidate CliniChem, an acceptable accounting principle at that time. The management of Shire believes that their accounting policies would have required Shire to continue to consolidate CliniChem, also an acceptable accounting alternative at the date of the spin-off and a policy that conforms with the later guidance issued under EITF 99-16. The effect of this accounting policy alignment is to reduce the net income from continuing operations previously reported by BioChem now included in the pooled financial statements for 2000 and 1999 by $38.8 million and $45.5 million respectively. On 15 December 2000 BioChem reacquired CliniChem. This acquisition has been reflected in the accompanying financial statements using purchase accounting. The allocation of the purchase price to the acquired net assets and liabilities is discussed in note 2 above.

The deferred financing costs at 31 December 2001 were in respect of the $400 million convertible loan note (see note 16). These costs are being amortised over ten years. The deferred financing costs at 31 December 2000 were in respect of a $125.0 million long-term loan (see Note 16), which was being amortised over the five-year term of the loan. This loan was repaid in full during the year 2001. Tooling costs are being amortised over the manufacturing contract period. The Company does not own the tools but has a non- cancellable right to use the tools during the contract period. Production commenced during 2001 and, based on expected production volumes, $1.3 million of the costs are classified as current at 31 December 2001 (31 December 2000: $1.0 million) Included within other current assets at 31 December 2001 is valued added tax recoverable of $5.4 million (31 December 2000: $1.9 million).

The Company made investments in private companies and partnerships totalling $13.2 million during 2001. Total significant additions included investments made to Genechem Technologies Venture Fund and Genechem Therapeutic of approximately $4.7 million (C$ 7.5 million), EGS Private Healthcare of approximately $2.2 million (C$3.3 million) and Qualia Computing of approximately $6.0 million (C$9.2 million). During the year ended 31 December 2001, the Company wrote down the cost of investments by $24.9 million as part of the one time charge resulting from the merger with BioChem, due to a non-temporary impairment. b) Investments in public companies In December 2000, the Company signed a research, development and licensing agreement with CeNeS Pharmaceuticals plc for the development of CeNeS dopamine D1 agonist programme for the treatment of Parkinson’s disease. The Company undertook to make milestone payments and pay CeNeS royalties on products developed under the agreement. The Company made an equity investment in CeNeS of approximately $0.7 million and undertook to fund all development work. During the year ended 31 December 2001 the Company recorded an impairment charge of $0.7 million due to a non-temporary impairment. The Company recorded a loss of $0.1 million in respect of non-current investments marked to market at 31 December 2000. As explained above, the investment to which this relates has suffered a permanent diminution in value, and hence the cumulative marked to market adjustment has been recorded through the Consolidated Statement of Operations for the year ended 31 December 2001. c) Equity method investment The Company has accounted for its commercialisation partnership with GSK (through which the products 3TC and ZEFFIX are marketed in Canada) using the equity method of accounting as the Company owns a 50% share of the partnership. Accordingly, the Company’s share of the earnings of the partnership is included in “Other income, net” and the related equity investment is included above. The amount included in “Other income, net” for the year ended 31 December 2001 was $2.0 million.

The building, purchased in October 2000, was not depreciated during the year ended 31 December 2000, as it did not become operational until March 2001. Also included within land and buildings at 31 December 2000 was $17.3 million in respect of items considered construction in progress that therefore were not depreciated.

31 December 2001 $000 2002 4,325 2003 827 2004 400,827 2005 827 2006 – Thereafter – 406,806

The principal payments presented above have been calculated on the basis that the $400.0 million convertible notes due 2011 convert to ordinary shares at the earliest opportunity, which is 21 August 2004. Further details are presented below. Convertible notes due 2011 On 15 August 2001, Shire Finance Limited, a wholly-owned subsidiary of the Company, placed an offering of $350.0 million principal amount of Guaranteed Convertibles Notes due 2011 with international institutional investors at an issue price of 100%. In connection with the issue, the initial purchasers exercised in full the option to subscribe or procure subscribers for an additional $50.0 million principal amount of notes. The total principal amount of the issue was therefore $400.0 million. The notes are guaranteed by the Company and are convertible into redeemable preference shares of the issuer which upon issuance will be immediately exchanged for either (i) ordinary shares or (ii) American Depository Shares (ADSs) of Shire, or, at the issuer’s option, cash. The notes bear interest of 2% per annum, paid semi-annually. The effective initial exchange price is $20.154 per ordinary share and $60.4625 per ADS. This exchange price represented a premium of 25% over the closing price of Shire ADSs on August 14, 2001. Investors have the right to require the issuer to redeem the notes at par on 21 August 2004, 2006 or 2008. Subject to certain conditions, the notes will be callable after 21 August 2004. The interest expense recorded in the year ended 31 December 2001 was $2.9 million (2000: nil).

Shire Pharmaceuticals Group plc 55 Notes to the financial statements

16 Long-term debt continued Five year term loan The Company entered into a $125.0 million five year term loan and a $125.0 million revolving credit facility with Credit Suisse First Boston (CSFB), previously known as DLJ Capital Funding, Inc., on 19 November 1999. This loan replaced an existing $125.0 million loan facility in the name of Roberts Pharmaceutical Corporation that had been taken out to finance the acquisition of PENTASA in 1998. The new loan was in the name of the parent company, Shire Pharmaceuticals Group plc. The applicable interest rate ranged between 0.5% and 1.5% over the higher of the prime rate of CSFB or the Federal Funds Rate plus 0.5% or between 1.5% and 2.5% over the London Interbank Overnight Rate (as adjusted in accordance with the loan agreement), in each case depending on the Company’s credit rating. All obligations under the facility were jointly and severally guaranteed by the Company and by its subsidiaries and were initially secured by all material property owned by the Company and its subsidiaries and the capital stock of the subsidiaries. If the Company’s credit rating reached specified levels, the facility would no longer be secured. The facility contained covenants and maintenance tests that required the Company to maintain a minimum net worth, a specified leverage ratio and a specified coverage ratio. At 31 December 2000 the Company satisfied the aforementioned covenants and maintenance tests. In May 2001, the Company repaid the term loan in full and terminated the credit facility. Deferred financing costs of $2.6 million were written off and expressed as an extraordinary item. Unsecured Convertible Zero Coupon Loan Note The Company financed the purchase of intellectual property relating to the manufacture of ADDERALL from Arenol Corporation by a total of $11.8 million in loan notes. On 5 March 1999 the Company issued a $5.8 million principal amount Unsecured Convertible Zero Coupon Loan note due 30 July 2001 (the First Loan Note) and a $6.0 million principal amount Unsecured Convertible Zero Coupon Loan Note due 30 July 2004 (the Second Loan Note). Both loan notes are in the name of the parent company, Shire Pharmaceuticals Group plc. The agreement provides for the cancellation of certain specified amounts of the aggregate principal amount of the First Loan Note and of such amounts of the Second Loan Note on certain dates to the extent of certain indemnified losses or, to the extent that such amounts of the First Loan Note or the Second Loan Note (together the Loan Notes) are not so cancelled, for their conversion into ordinary shares. The number of ordinary shares is calculated by dividing the amount not cancelled by the lower of £3.565 (approximately $5.75) and the midweek closing price of the ordinary shares on the London Stock Exchange on the relevant date. Translation from pounds sterling to US dollars is made using the exchange rate on the relevant date. The Company issued 533,279, 560,076, 541,478 and 295,061 ordinary shares on 13 March 2000, 3 August and 6 November 2000 and 30 July 2001, respectively to Arenol Corporation (or its nominee broker) in consideration of the conversion of part of each of the Loan Notes in the Company. Promissory note Included in the current portion of long-term debt at 31 December 2000 is an $80.0 million promissory note to a shareholder, bearing interest at 5% per annum. This note was repaid in full during 2001. Canadian federal and provincial government loan The Company has a Canadian federal and provincial government loan outstanding of $3.1 million (C$5.0 million). This facility is non- interest bearing and is repayable in annual instalments of $0.8 million (C$1.2 million) commencing in May 2002. Bank term loan The Company has a bank loan at 31 December 2001 bearing interest at the lender’s prime rate. The loan is secured by a charge on land and buildings, and is repayable in annual instalments of $0.4 million (C$0.6 million) with a final payment of $2.4 million (C$3.6 million) in May 2002. The loan is renegotiable for an additional five year period.

56 Shire Pharmaceuticals Group plc 18 Financial instruments The following methods and assumptions were used to estimate the fair value of each material class of financial instrument: Cash and cash equivalents – carrying amount approximates fair value due to the short-term nature of these instruments. Marketable securities and other current asset investments – the fair value of marketable securities is estimated based on quotes obtained from brokers. Investments – non-current investments with readily determinable market values are marked to market. The fair value of investments in private entities and non-traded securities is measured by valuation methodologies including discounted cash flows. Accounts receivable – carrying amount approximates fair value due to the short-term nature of these instruments. Accounts payable and accrued expenses – carrying amount approximates fair value due to the short-term nature of these instruments. Long-term debt – the fair value of long-term debt is estimated based on the discounted future cash flows using currently available interest rates or, where the debt instrument is traded, by reference to the market price. The carrying amounts and corresponding fair values of financial instruments at 31 December 2001 and 2000 were as follows: Carrying amount Fair value $000 $000 31 December 2001 Financial assets: Cash and cash equivalents 118,400 118,400 Marketable securities and other current asset investments 723,911 723,911 Investments 68,743 68,743 Financial liabilities: Accounts payable and accrued expenses 167,152 167,152 Long-term debt 406,806 394,206

The carrying amounts in the table are included in the Consolidated Balance Sheet under the indicated captions.

19 Leases and other commitments a) Leases The Company leases facilities, motor vehicles and certain office equipment under operating leases. The Company’s commitments under the non-cancellable portion of all operating leases for the next five years and thereafter as of 31 December 2001 are as follows: 31 December 2001 $000 2002 6,166 2003 3,545 2004 1,693 2005 599 2006 311 Thereafter 1,996 14,310

Shire Pharmaceuticals Group plc 57 Notes to the financial statements

19 Leases and other commitments continued b) Contingent liabilities i) Phentermine Shire US Inc. (Shire US) has been named as a defendant in approximately 3,784 lawsuits, in both US federal and state courts, which seek damages for, among other things, personal injury arising from phentermine products supplied for the treatment of obesity by Shire US and several other pharmaceutical companies. Shire US has been sued as a manufacturer and distributor of phentermine, an anorectic used in the short-term treatment of obesity and one of the products addressed by the lawsuits. The suits relate to phentermine either alone or together with fenfluramine or dexenfluramine. As at 31 December 2001 Shire US had been named as a defendant in approximately 3,784 cases. Shire US has been dismissed from 3,619 cases. As at 31 December 2001 approximately 111 cases were pending dismissal. The lawsuits generally allege the following claims: the defendants marketed phentermine and other products for the treatment of obesity and misled users about the products and territory dangers associated with them; the defendants failed adequately to test phentermine individually and when taken in combination with the other drugs; and the defendants knew or should have known about the negative effects of the drugs and should have informed the public about such risks and/or failed to provide appropriate warning labels. Shire US became involved with phentermine through its acquisition of certain assets of Rexar in January 1994. In addition to Shire US potentially incurring liability as a result of its own production of Oby-Cap, the plaintiffs may additionally seek to impose liability on Shire US as successor to Rexar. Class certification has been sought for certain of the claims made against Shire US. In addition, pending US federal lawsuits have been consolidated as a multi-district litigation in the Eastern District of Pennsylvania. Shire US intends vigorously to defend all the lawsuits and pursue all available reasonable defences. Shire US currently has only one lawsuit pending against it in federal court. Shire US denies liability on a number of grounds including lack of scientific evidence that phentermine, properly described, causes the alleged side effects and that Shire US did not promote phentermine for long-term combined use as part of the “fen/phen” diet. Accordingly, Shire US intends to defend vigorously any and all claims made against the Group in respect of phentermine and believes that liability is neither probable nor quantifiable at this stage of litigation. Legal expenses have been paid by Eon, the supplier to Shire US, or Eon’s insurance carriers but such insurance is now exhausted. Eon has agreed to defend and indemnify Shire US in this litigation pursuant to an agreement dated 30 November 2000 made between Eon and Shire US. ii) ADDERALL On 22 September 2000, a lawsuit was filed against Shire in the United States District Court for the District of North Dakota. The suit involves an incident in 1999 in which a young North Dakota man, Ryan Ehlis, shot and killed his infant daughter and wounded himself, allegedly as a result of a psychotic reaction to ADDERALL. Mr Ehlis’ physician had prescribed ADDERALL for the treatment of ADHD. Shire filed its answer to the complaint on 24 November 2000 and discovery related to the litigation is ongoing. On 3 October 2001, a lawsuit was filed against Shire in a Kentucky state court. The lawsuit involves a 34 year old woman who alleges that she experienced a psychotic episode from her ingestion of ADDERALL which led to the death of her child in an auto accident. Shire intends to robustly defend such action. On 27 July 2001, Shire received service of a complaint filed in state court in Texas that alleged that ADDERALL caused or contributed to a stroke. The plaintiff, an adult female aged 39, was prescribed ADDERALL as treatment for her ADHD. The complaint alleges that the plaintiff used ADDERALL during the period from January 1999 to September 1999. Also named as defendants are two doctors who were involved in diagnosing the plaintiff’s ADHD and for prescribing ADDERALL for its treatment. Discovery in this litigation is ongoing. Shire intends to robustly defend such action. iii) AGRYLIN Shire US has been named as a defendant in a recently filed lawsuit in a Texas state court involving AGRYLIN. The complaint was filed in late December and served on Shire on 26 December 2001. Shire’s contract manufacturer for AGRYLIN, , Inc., is also a named defendant. The complaint alleges that the plaintiff suffered a debilitating stroke due to the fact that the plaintiff was allegedly unable to procure this product in some fashion. Shire has filed an answer to the complaint in which it denies the allegations in the plaintiff’s original petition. Shire intends to robustly defend such action. iv) Emory Shire BioChem is involved in worldwide patent disputes with Emory University (Emory) relating to lamivudine wherein Shire BioChem is opposing certain patents and patent applications of Emory and wherein Emory is opposing certain patents and patent applications of Shire BioChem. Further detail regarding these disputes is provided below. In November 2001, Shire and GlaxoSmithKline (GSK) signed an agreement as to the key terms of a global settlement agreement with Emory. The parties are in the process of finalising the settlement agreement. Pursuant to the settlement agreement, Emory will grant Shire and GSK an exclusive licence under Emory’s patent rights for lamivudine. The agreement provides for the resolution of the below noted worldwide patent disputes between the parties relating to lamivudine. The settlement involves an upfront payment to Emory by Shire of $2.5 million and a royalty payment from Shire of 0.5% on worldwide sales of lamivudine over an 11 year period commencing on 1 January 2001 and a licence under Shire’s FTC patent rights, in consideration for the settlement of all claims against Shire and GSK relating to lamivudine. The total cost to Shire in 2001 of the settlement (including upfront payment) was $7.7 million.

58 Shire Pharmaceuticals Group plc 19 Leases and other commitments continued Emory filed oppositions to two of Shire BioChem’s granted patent applications in Europe which cover oxathiolane nucleosides including lamivudine and dioxolane nucleosides, including troxacitabine, related nucleoside analogues and use of these analogues for treating viral infections. In oral hearings held in 1999, both of these oppositions were dismissed by the Opposition Division of the European Patent Office. Emory is not pursuing its appeal of the decision relating to oxathiolanes. Emory has not to date filed revocation actions with respect to any Shire BioChem lamivudine patents in issue in individual European countries. Emory has filed an appeal against the dioxolane-related decision and this appeal is pending in the European Patent Office. This appeal does not relate to lamivudine and is not included in the settlement agreement with Emory. In Japan, Emory filed an opposition to Shire BioChem’s granted patent which covers lamivudine, related analogues and use of the analogues for treating viral infections. The Trial Board of the Japanese Patent Office dismissed Emory’s opposition to Shire BioChem’s patent covering lamivudine. Emory has filed revocation actions in Australia and South Korea against Shire BioChem’s granted patents covering lamivudine. Shire BioChem is aggressively defending these patents. On 23 July 1996, Emory filed a complaint in the US alleging infringement from the commercialisation of EPIVIR by Shire BioChem and GSK, Shire BioChem’s exclusive licencee in the US, of an Emory US patent granted that same day. Shire BioChem considers this patent infringement suit to be without merit and has successfully challenged the validity of Emory’s patent. On 19 May 1998, the US Patent Office (USPTO) declared an interference between the Emory patent that is the subject of a lawsuit and a pending patent application of Shire BioChem. The Board of Patent Appeals and Interferences issued a decision on 21 December 2000 invalidating Emory’s patent. Emory has appealed the decision. Pusuant to the lamivudine settlement agreement, Emory will accept the Board’s decision as final and the infringement suit will be dismissed with prejudice. Emory has obtained a granted patent application in Europe relating to oxathiolane nucleosides, including lamivudine. Shire BioChem and GSK filed an opposition to this grant and are vigorously opposing the grant. An examined patent application filed by Emory, claiming lamivudine, was successfully opposed by Shire BioChem in Australia and Norway. Emory has filed an appeal from the Australian decision in the Federal Court of Australia. Shire BioChem also filed an appeal from certain portions of the decision. An examined patent application filed by Emory claiming lamivudine was also opposed by Shire BioChem in Japan. The opposition was dismissed in April 1999 because it was improperly filed by a representative who had previously represented Emory. Notwithstanding the dismissal, the Japanese Patent Office issued an ex-officio action rejecting all of Emory’s claims. There can be no assurance that Emory will not be able to overcome this rejection. An examined patent application filed by Emory claiming lamivudine was opposed by Shire BioChem and GSK in South Korea and such Emory claims to lamivudine were cancelled by the South Korean Patent Office. Shire BioChem is aware that Emory has filed patent applications in other countries, which Shire BioChem believes may claim similar subject matter. v) Yale On 23 November 1999, the USPTO declared an interference between BioChem’s hepatitis B patent for lamivudine and a patent application filed by Yale University (Yale) claiming methods of treating hepatitis B using lamivudine. The Company believes that this application is licenced to Vion Pharmaceuticals, Inc. (Vion), formerly known as OncoRx, Inc., a New Haven, Connecticut-based company. The Company believes that its patent is valid and intends to vigorously defend the patent. The Company is not aware of corresponding patent applications by Yale or Vion in countries other than the US. On 14 April 2000, the USPTO declared a further interference between BioChem’s hepatitis B patent for lamivudine and a patent application by GSK claiming methods of treating hepatitis B using lamivudine. There is no guarantee that Shire will be successful in both interferences and that Shire’s patent will be maintained. There can also be no reassurance that Yale will not prevail in both interferences and obtain claims in the US directed to methods of treatment for hepatitis B using lamivudine. vi) Interests in companies and partnerships The Company has undertaken to subscribe to interests in companies and partnerships for amounts totaling $37.7 million. As at 31 December 2001 an amount of $20.1 million (31 December 2000: $17.1 million) has been subscribed. In addition, the Company has undertaken to subscribe to additional amounts and to pay royalties on certain future sales upon realisation of certain conditions. vii) FLUVIRAL The Company has signed a ten-year contract with the Government of Canada to assure a state of readiness in the case of an influenza pandemic (worldwide epidemic) and to provide influenza vaccine for all Canadian citizens in such an event. Under the contract, Shire Biologics will also supply the Government of Canada with a substantial proportion of its annual influenza vaccine requirements over the ten-year period. The value of the agreement may exceed C$300 million (approximately $190 million) over the ten-year term, with an option for the Government of Canada to extend the contract. The concept of a state of readiness against an influenza pandemic requires the development of sufficient infrastructure and capacity in Canada to provide 100% of domestic vaccine needs in the event of an influenza pandemic. Canada would require 32 million doses of single-strain (monovalent) flu vaccine within a production period of 16 weeks. Shire Biologics will therefore begin expanding its current production capacity in order to meet this objective within a five-year period. Shire Biologics is committed to C$4.5 million (approximately $2.8 million) of capital expenditure on immoveables for the purpose of achieving the level of pandemic readiness required. In addition, a performance bond equal to 10% of the minimum estimated contract value in any year, which for 2001/2002 is C$17.5 million (approximately $11 million), would become payable to the Government of Canada if contracted penalty clauses were triggered. viii) Other matters In addition, the Company is involved in other claims and lawsuits in the normal course of business. It is not possible at this time to determine the ultimate outcome of any of these claims. Shire Pharmaceuticals Group plc 59 Notes to the financial statements

20 Related parties a) Mr Spitznagel Mr Spitznagel, a former director of the Company, who resigned during the year ended 31 December 2001, entered into a consultancy agreement with the Company in December 1999, which provided that; if he had good reason, as defined in his service agreement with Roberts, to terminate his employment with Roberts under his service agreement, the Company would cause Roberts to provide him with the payments and benefits he would be entitled to upon a “good reason” termination; Mr Spitznagel would provide consulting services to the Company for at least 42 months following the acquisition of Roberts, unless Mr Spitznagel terminated the consultancy agreement prior to the end of the 42nd month upon 30 days’ notice; and the Company would pay Mr Spitznagel at a rate of $400,000 per annum for his consulting services, $150,000 per annum as an office holder, $250,000 per annum to comply with certain restrictive covenants contained therein and $150,000 per annum for tax, financial and estate planning advice, life insurance and health insurance. b) Dr Bellini Prior to the Company’s merger with BioChem, Dr Bellini entered into an agreement with BioChem whereby BioChem granted to Dr Bellini an option to purchase from BioChem its interest in a company that owned land and buildings located on Province Island, Quebec for the fair market value of C$225,000 (approximately $141,000). Dr Bellini exercised his option and the transaction was completed in accordance with the terms of the option agreement on 29 November 2001. c) Professional fees The Company incurred professional fees with a law firm, in which the Hon James Andrews Grant is a partner, totalling $1.9 million for the year ended 31 December 2001 ($0.4 million for the year ended 31 December 2000 and $0.2 million for the year ended 31 December 1999). d) Immunosystems BioChem Immunosystems Inc (Immunosystems), formally a wholly owned subsidiary of BioChem, was sold in February 2000 to a third party. Dr Bellini, the former Chief Executive Officer of BioChem, continued as a director of Immunosystems. In December 2001, the Company acquired a 19.9% equity interest in Immunosystems in consideration for the release of a debt owing to the Company from Immunosystems. This debt existed prior to the Company’s merger with BioChem. As part of the same transaction, the Company was released from a pre-existing BioChem guarantee over other Immunosystems liabilities.

21 Net income/(loss) per share Basic net income/(loss) per share is based upon the income 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: 2001 2000 1999 $000 $000 $000 Years ended 31 December Numerator for basic and diluted net income/(loss) per share 38,759 211,727 (47,432)

The calculation of weighted average number of shares for the year ended 31 December 2000 does not include convertible debt because, after eliminating interest charged in the income statement from the numerator, the inclusion would be anti-dilutive. The calculation of weighted average number of shares for the year ended 31 December 1999 does not include potentially dilutive stock options and convertible debt because the inclusion would be anti-dilutive. The warrants included in the diluted net income per share calculation are issuable in respect of a research and development agreement. A charge of $4.5 million has been included in the results for the year ended 31 December 2001. No warrants have been issued as at 31 December 2001 although an obligation does exist. 60 Shire Pharmaceuticals Group plc 22 Analysis of revenue, operating income/(loss), assets and reportable segments The Company has disclosed segment information for the individual operating areas of the business, based on the way in which the business is managed and controlled. Shire’s principal reporting segments are geographic, each managed and monitored separately and serving different markets.

22 Analysis of revenue, operating income/(loss), assets and reportable segments continued Material customers In the periods set out below, certain customers accounted for greater than 10% of total revenues: 2001 2000 1999 Years ended 31 December $000 $000 $000 Customer A 176,941 132,913 100,267 Customer B 123,350 80,293 54,498

23 Other charges Year ended 31 December 2001 a) BioChem merger As a result of the merger with BioChem on 11 May 2001, the Company recorded pre-tax charges totalling $177.0 million, comprising asset impairment and restructuring costs ($85.4 million), merger-related transaction expenses ($83.5 million), and a loss on the sale of a duplicated facility in Toronto, Canada ($8.1 million). The restructuring costs include an impairment charge of $20.9 million to adjust intangible asset values, primarily trademark and patent costs but also an element of product rights, to their estimated fair value. These charges are consistent with the Company’s accounting policy to review periodically the carrying value of the intangibles and evaluate whether there has been any impairment in the value of those intangibles as compared with estimated undiscounted future cash flows relating to those intangibles. Other asset impairments included the write-down of long-term unquoted investments ($24.9 million) and a write-down of $30.8 million to a debenture held by BioChem, which was received on divestiture of its diagnostics subsidiary. These charges are consistent with the Company’s policy to provide for other than temporary impairments in investment by reference to the fair value of the investment using established financial methodologies. There was also a total of $8.8 million recorded in respect of employee-related costs. The employee terminations related to the closure of the Toronto facility and the elimination of duplicate positions across the combined organisation. Shire’s existing Canada-based sales and marketing operations in Toronto have been combined with those of BioChem in Laval. A total of 57 employees were identified to be terminated. As of 31 December 2001 all of the planned terminations were completed. b) Product disposals During the third quarter of 2001, we disposed of certain non-strategic products for net proceeds of approximately $4.5 million. A loss on disposition of $2.0 million was recorded. Year ended 31 December 2000 As a result of the merger with BioChem, the Company incurred a charge of $26.9 million relating to the acquisition of in-process research and development in accordance with SFAS No. 2. Year ended 31 December 1999 As a result of the merger with Roberts on 23 December 1999, which was accounted for as a pooling of interests, the Company recorded charges totalling $135.2 million pre tax which comprised asset impairments ($48.5 million), merger-related transaction expenses ($32.3 million), restructuring costs ($43.6 million), loss on product dispositions ($5.8 million) and other charges ($5.0 million). These charges are disclosed separately within operating expenses in the consolidated statements of operations. The Company recorded an impairment charge of $34.2 million to adjust intangible asset values, primarily product rights, to their estimated fair value. These charges are consistent with the Company’s accounting policy to review periodically the carrying value of the intangibles and evaluate whether there has been any impairment in the value of those intangibles as compared with estimated undiscounted future cash flows of the products. Other asset impairments consisted of the write-off of inventory held for research and development work and duplicate equipment ($3.2 million), adjustments to the carrying value of the RiboGene investment to market value at 31 December 1999 ($7.6 million), and write-down of receivables to their estimated realisable value ($3.5 million). The components of the restructuring charge were as follows: $m Employee termination costs 37.9 Property 5.7 43.6

In December 1999, the decision was made to close the office facility in Eatontown, New Jersey, and consolidate the sales and marketing operations into the existing facility in Florence, Kentucky, and to transfer the research and development activities to Shire’s facility in Rockville, Washington. Similarly, Roberts’ sales and marketing operation in the UK was combined with Shire’s established operation in Andover, Hampshire. The property at Eatontown was written down to its estimated fair value and subsequently sold. As a result of the restructuring and elimination of duplicate facilities, the Company identified a number of sales and marketing, research and development and administrative positions to be terminated. These employees were notified of their termination prior to 31 December 1999. The employee termination costs consisted of payments for severance, medical and other benefits, outplacement counselling, acceleration of pension benefits and excise taxes. The Company completed the restructuring programme during the fourth quarter of 2000, and the restructuring reserve of $43.6 million was fully utilised by 31 December 2000.

62 Shire Pharmaceuticals Group plc 24 Retirement benefits a) Personal defined contribution pension plans The Company makes contributions to defined contribution retirement plans that together cover substantially all employees within the Group. For the defined contribution retirement plans, the level of Company contribution is fixed at a set percentage of employees’ pay. Company contributions to personal defined contribution pension plans totalled $4.9 million, $2.6 million and $1.6 million for the years ended 31 December 2001, 2000 and 1999 respectively, and were charged to operations as they became payable. b) Defined benefit pension plan Roberts Pharmaceutical Corporation, a company with which the Company merged in December 1999, operated a defined Supplemental Executive Retirement Plan (SERP) for certain US employees, which was established in 1998. This plan was available to former employees of Roberts who met certain age and service requirements. As part of the restructuring of the Group following the merger, the SERP was closed to new members and contributions have ceased being paid into the plan for existing members. As part of this arrangement, the Company paid a lump sum contribution into the plan of $18.0 million, the result of which is that the Company has no future contributions under the plan. In accordance with EITF 97-14, the asset and liability of $14.4 million and $11.3 million respectively are shown on the balance sheet within the categories “Investments” and “Other non-current liabilities”. See notes 12 and 17 above.

25 Income taxes continued A comparison of the provision for income taxes as reported to a (provision)/benefit based on federal statutory rates and consolidated income before income taxes is as follows: 2001 2000 1999 Years ended 31 December $000 $000 $000 (Provision)/benefit at federal statutory rates (39,066) (90,787) 4,757 Adjusted for: Permanent differences (32,268) (963) (6,783) Difference in taxation rates 32,307 44,233 25,755 Adjustment to prior year liabilities 2,958 (1,950) 4,004 Goodwill amortisation (3,309) (3,783) (9,758) Other (6,087) (2,652) (531) Movement in valuation allowance (27,395) 8,238 (39,107) Provision for income taxes (72,860) (47,664) (21,663)

Permanent differences arising in the year ended 31 December 2001 are mainly attributed to non-deductible one time merger-related costs incurred as a result of the Company’s merger with BioChem during the year. An analysis of the deferred tax asset is as follows: 31 December 31 December 2001 2000 $000 $000 Losses carried forward 170,512 108,617 Amounts deductible when paid 6,238 34,307 Valuation reserves and provisions 7,874 6,915 Other 6,267 1,447 190,891 151,286 Valuation allowance (125,565) (97,585) Deferred tax assets 65,326 53,701 Excess of tax value over book value of assets (33,022) (20,168) Net deferred tax assets 32,304 33,533

Valuation allowances against deferred tax assets have not been provided to the extent that it is more likely than not that future income and tax planning strategies will enable losses brought forward to be utilised. The income/(loss) before taxes by tax jurisdiction is as follows: 2001 2000 1999 Years ended 31 December $000 $000 $000 US 200,160 77,974 (33,924) UK (101,756) (37,577) (33,996) Canada (164,188) 13,663 (50,806) Other 177,403 205,331 105,136 111,619 259,391 (13,590)

64 Shire Pharmaceuticals Group plc 26 Stock incentive plans The Company has adopted the disclosure-only provisions of SFAS No. 123, “Accounting for Stock-Based Compensation,” but applies Accounting Principles Board Opinion No. 25 (APB 25) and related interpretations in accounting for its plans. In the years ended 31 December 2001, 2000 and 1999 the Company recognised a charge under APB 25 of $2.3 million, $21.9 million and $11.9 million respectively. Had compensation for stock options awarded under the plans been determined in accordance with SFAS 123, the Company’s net income/(loss) and per share data would have been changed to the pro forma amounts indicated below:

2001 2000 1999 Years ended 31 December $000 $000 $000 Net income/(loss) As reported 38,759 211,727 (47,432) Pro forma 8,791 227,018 (37,919) Income/(loss) per share As reported – basic 7.9c 43.8c (9.8)c As reported – diluted 7.7c 42.8c (9.8)c Pro forma – basic 1.8c 47.0c (7.8)c Pro forma – diluted 1.7c 45.9c (7.8)c

The fair value of stock options used to compute pro forma net income/(loss) and per share disclosures is the estimated present value at grant date using the Black-Scholes option-pricing model with the following weighted average assumptions: 2001 2000 1999 Years ended 31 December $000 $000 $000 Risk free interest rate 3.43 – 5.22% 5.68% – 6.58% 4.76% – 6.25% Expected dividend yield 0% 0% 0% Expected life 5 years 5 years 5 years Expected volatility 59.5% 64.2% 53.4%

In a period of five years, not more than 5% of the issued share capital of the Company may be placed under option under any employee share scheme. In addition, the following terms apply to options that may be granted under the various plans: Stock Purchase Plan: the maximum number of ordinary shares which shall be made available for sale is 2,000,000. 2000 Executive Scheme: the maximum number of shares over which incentive stock options may be granted under Part B of the scheme is 25,000,000.
