Dealing by Directors
Companies Act 1985 Sections 324/329

We hereby inform you that the interest of David R Brennan, a Director of the Company, in the American Depositary Shares (ADSs) of AstraZeneca PLC has changed as detailed below. One ADS equals one Ordinary Share.

As previously notified on 28 March 2006, Mr Brennan became unconditionally entitled to 31,780 ADSs on the partial vesting of an award under the terms of the AstraZeneca US Executive Performance Share Plan. At that time, Mr Brennan elected to defer the value of those ADSs, less certain mandatory tax deductions, into the AstraZeneca US Executive Deferred Compensation Plan, a unitised stock fund in which Mr Brennan, in common with other participating US executives, is deemed to have a notional interest in ADSs calculated by reference to the fund value and the closing price of AstraZeneca ADSs. This deferral occurred automatically on 28 April 2006, following which Mr Brennan has a notional interest in 28,831 ADSs in the AstraZeneca US Executive Deferral Plan as at 28 April 2006 based on that day’s closing price of US$55.13.

In total, Mr Brennan now has an interest in 167,453 AstraZeneca ADSs and 79,461 Ordinary Shares, including the notional interest in ADSs in the AstraZeneca US Executive Deferred Compensation Plan referred to above.

Item 2

AstraZeneca Discontinues Development of GALIDA™ (tesaglitazar)

AstraZeneca today announced the discontinuation of the GALIDA development programme. GALIDA is a dual PPAR alpha and gamma agonist and was in phase III development for the treatment of the glucose and lipid abnormalities associated with type 2 diabetes.

Following analysis and interpretation of recently obtained results from the first four of eight Phase III clinical trials (GALLANT 6,7,8 and 9) and one Phase II trial (ARMOR), which were reviewed in consultation with external experts, the company considers that the overall benefit / risk profile is unlikely to offer patients significant advantage over currently available therapy.

Central to the decision is data showing elevations in serum creatinine and an associated decrease in Glomerular Filtration Rate (GFR). The magnitude of the serum creatinine elevation was greater than anticipated based on earlier clinical studies. Such elevations reversed towards baseline upon stopping treatment with the drug and have not been associated with kidney toxicity.

There is no immediate safety concern for patients and all primary efficacy endpoints were met in the Phase III trials. Patients are advised to speak with their physician before stopping their treatment. All ongoing GALIDA clinical studies will now be brought to a close and physicians will be advised to switch patients to the alternative available therapies at their next scheduled visit. There are currently 2,245 patients taking GALIDA within clinical trials.

David Brennan, Chief Executive Officer, AstraZeneca PLC, commented: “We have acknowledged that GALIDA was in a class with a high degree of uncertainty






and the decision to discontinue is disappointing. We remain committed to further strengthening AstraZeneca’s pipeline of new medicines both from our own research efforts and through the continued pursuit of external opportunities to enhance our business.”

Further analysis of data from the GALIDA development programme is ongoing and the company will make the data available as appropriate through scientific presentation, publication and via the company’s Clinical Trials Website once completed.

AstraZeneca has other PPAR agonist programmes in development and learning from the GALIDA programme will be applied to these once final analysis of the data is concluded.

15 May 2006

     AstraZeneca announces major long-term strategic investment in biological therapeutics with a recommended £702 million cash offer for Cambridge Antibody Technology Group plc at 1,320p per share and 1,320p per ADS

Summary

The boards of AstraZeneca and CAT announce that they have agreed terms of a recommended cash offer to be made by AstraZeneca to acquire the entire issued and to be issued share capital of CAT not otherwise held by AstraZeneca. The Offer for each CAT Share will be at 1,320 pence in cash and the Offer for each CAT ADS will be at 1,320 pence in cash, equivalent to US$24.96 per ADS (based on the exchange rate as at 12 May 2006). The Offer values CAT’s existing issued share capital, excluding AstraZeneca’s existing shareholding in CAT, at approximately £567 million and the entire issued share capital of CAT at approximately £702 million.

Building on the success of an existing collaboration, and recognising the increasing importance of biotechnology in medical research, CAT will become central to AstraZeneca’s plans to establish a major international presence in the research and development of biological therapeutics. AstraZeneca’s science base already possesses discovery and development capabilities for new biological medicines which will be combined with those of CAT and expanded through further investment. This enhanced research capability, combined with AstraZeneca’s global development, marketing and sales resources, will establish an international platform capable of accelerating the delivery of new medicines in AstraZeneca’s prioritised disease areas, embracing both monoclonal antibodies and novel biological entities.

Highlights

      In late 2004, AstraZeneca and CAT entered into a Collaboration and Licence Agreement jointly to discover and develop human monoclonal antibodies and AstraZeneca acquired a shareholding in CAT that currently represents approximately 19.2% of the issued share capital.
   
      AstraZeneca now intends to create a major R&D capability to deliver biological therapeutics, and the integration of CAT is central to these plans. The new organisation will be led from CAT’s Cambridge headquarters and will be distinct from but complementary to AstraZeneca’s small molecule capability.
   
      CAT’s capabilities, when combined with AstraZeneca’s global development and marketing expertise, will deliver an expanded pipeline of novel biological therapeutics to address unmet medical needs of patients in AstraZeneca’s targeted disease areas.
   
      AstraZeneca’s ability to bring additional resources and capabilities to CAT will allow it to develop CAT’s technology platform beyond its current capability and across a number of therapeutic areas including Respiratory & Inflammation, Oncology & Infection, Neuroscience, Cardiovascular and Gastro-intestinal.

1






      CAT also provides AstraZeneca with several other substantial assets beyond its current scientific capabilities. These include a royalty stream on the sales of HUMIRA®, potential milestones and royalties on CAT’s other licensed products and access to CAT’s proprietary pipeline (including CAT-3888 in Phase II and CAT-354 in Phase I), which will be integrated into AstraZeneca’s development portfolio. In addition, CAT had a balance of net cash and liquid resources of approximately £152 million as at 31 December 2005.
   
      The acquisition will not alter AstraZeneca PLC’s EPS guidance or its share repurchase programme for 2006.

The Offer

      The Offer represents a premium of approximately 66.9% to the closing mid market price of CAT’s Shares on the London Stock Exchange of 791 pence per share and 68.2% to the closing mid market quotation of CAT’s ADSs on NASDAQ of US$14.84 per ADS, each on 12 May 2006 (being the last dealing day prior to the date of this announcement) and a premium of 88.0% to CAT’s average price of 702 pence per share and a premium of 98.7% to CAT’s average price of US$12.56 per ADS over the last twelve months prior to the date of this announcement.
   
      The directors of CAT, who have been so advised by Morgan Stanley, consider the terms of the Offer to be fair and reasonable. In providing its advice, Morgan Stanley has taken into account the commercial assessments of the directors of CAT.
   
      The directors of CAT intend unanimously to recommend that CAT Shareholders accept the Offer, as the directors of CAT have irrevocably undertaken to do in respect of their own beneficial shareholdings.
   
      A Loan Note Alternative will also be made available to all CAT Shareholders (other than any CAT Shareholders in any Restricted Jurisdiction, which includes the United States).
   
      The Offer is conditional, amongst other things, upon receiving the required regulatory clearances. Further information on the terms and conditions to which the Offer will be subject are set out in Appendix 1 and will be set out in the Offer Document, which AstraZeneca intends to despatch to CAT Shareholders as soon as practicable.

Irrevocable undertakings

AstraZeneca has received irrevocable undertakings to accept the Offer from each of the directors of CAT, in respect of 190,569 CAT Shares in aggregate, representing approximately 0.36 per cent. of the existing issued share capital of CAT. All of these undertakings will remain binding notwithstanding a higher competing offer.

Further details of these irrevocable undertakings are set out in Appendix 3 to this announcement.

Commenting on the Offer, David Brennan, Chief Executive Officer of AstraZeneca PLC, said:

“This acquisition represents a major long-term strategic investment by AstraZeneca in novel biological therapeutics. It is our intention to both expand and broaden the scope of our discovery and development pipeline and we expect that, by 2010, up to a quarter of our candidates for full scale development will be biological therapeutic agents.

“The success of the collaboration over the last two years has demonstrated AstraZeneca’s and CAT’s complementary skills and expertise. We will now build on this success by combining CAT’s research and development capability in novel biological therapeutics with our own expertise in discovery, global product development and sales and marketing. Together we will create, for the

2






long term, an opportunity to introduce more medicines that will deliver real benefit to patients worldwide.”

Dr. Paul Nicholson, Chairman of CAT, said:

“After careful consideration, the board has unanimously decided to recommend the Offer to shareholders. The Offer recognises CAT’s leading position in the discovery and development of new antibody medicines and provides shareholders with an attractive premium through a cash offer.

“The Offer represents the successful culmination of CAT’s development since its founding in collaboration with the Laboratory of Molecular Biology of the UK Medical Research Council to the point where the excellence of its technologies and capabilities is now recognised globally. HUMIRA® is the first marketed product to come from CAT’s technologies and the first blockbuster product to come from the UK biotechnology industry. We are extremely pleased that AstraZeneca has recognised those qualities through this acquisition, demonstrating the successful growth and development of CAT as a UK biopharmaceutical company.”

Peter Chambré, CEO of CAT, said:

“CAT has developed outstanding capabilities in the rapidly growing field of antibody therapeutics. The excellent progress of the strategic alliance with AstraZeneca since December 2004 has demonstrated the power of combining the capabilities of both organisations and reflects the skills and dedication of CAT and AstraZeneca’s people. The Offer represents the next logical step in the successful development of CAT. By enabling the resources of AstraZeneca to be committed to realising the full potential of the CAT technologies and capabilities, there is the opportunity to develop a global leadership position in biological therapeutics and a major pipeline of new biological medicines for the benefit of patients. We are very excited about this next opportunity for the people who have made such an important contribution to the success of CAT.”

This announcement also does not constitute a Solicitation / Recommendation Statement under the rules and regulations of the US Securities and Exchange Commission (the "SEC"). The Offer will be made solely by means of an Offer Document and the Acceptance Forms accompanying the Offer Document, which will contain the full terms and conditions of the Offer, including details of how the Offer may be accepted.

CAT Shareholders are advised to read the Offer Document and the accompanying Acceptance Forms when they are sent to them because they will contain important information. CAT Shareholders in the United States are also advised to read the Tender Offer Statement and the Solicitation/Recommendation Statement because they will contain important information.

It should be noted that by virtue of the conflicting provisions of the City Code and the Exchange Act, the Panel has agreed that the Acceptance Condition can be structured so that the Offer cannot become or be declared unconditional as to acceptances until such time as all other conditions of the Offer have been satisfied, fulfilled or, to the extent permitted, waived. The Acceptance Condition in paragraph 1 of Appendix 1 has been amended accordingly.

Goldman Sachs International, which is authorised and regulated by the Financial Services Authority, is acting exclusively for AstraZeneca and no one else in connection with the Offer and will not be responsible to anyone other than AstraZeneca for providing the protections afforded to

5






clients of Goldman Sachs International or for providing advice in relation to the Offer or any other matters referred to in this announcement.

Morgan Stanley is acting exclusively for CAT in connection with the Offer and no one else and will not be responsible to anyone other than CAT for providing the protections afforded to clients of Morgan Stanley, or for providing advice in relation to the Offer or any other matters referred to in this announcement.

JPMorgan Cazenove Limited, which is authorised and regulated in the United Kingdom by the Financial Services Authority, is acting exclusively for CAT in connection with the Offer and no one else and will not be responsible to anyone other than CAT for providing the protections afforded to clients of JPMorgan Cazenove Limited, or for providing advice in relation to the Offer, or any other matters referred to in this announcement.

The availability of the Offer to CAT Shareholders who are not resident in and citizens of the United Kingdom or the United States may be affected by the laws of the relevant jurisdictions in which they are located or of which they are citizens. Such persons should inform themselves of, and observe, any applicable legal or regulatory requirements of their jurisdictions. Further details in relation to overseas shareholders will be contained in the Offer Document.

Unless otherwise determined by AstraZeneca or required by the City Code, and permitted by applicable law and regulation, the Offer, including the Loan Note Alternative, will not be made, directly or indirectly, in, into or from, and will not be capable of acceptance in or from Canada or Japan or any jurisdiction where to do so would constitute a breach of securities laws in that jurisdiction. Accordingly, copies of this announcement are not being, and must not be, mailed or otherwise forwarded, distributed or sent in, into or from Canada or Japan or any jurisdiction where to do so would constitute a breach of securities laws in that jurisdiction. Persons receiving this announcement (including custodians, nominees and trustees) should observe these restrictions and should not send or distribute this announcement in, into or from any such jurisdictions.

The Loan Notes to be issued in connection with the Offer have not been, nor will they be, registered under the Securities Act or under the securities laws of any state or other jurisdiction of the United States (or under the securities laws of any other jurisdiction, the residents of which AstraZeneca is advised to treat as Restricted Overseas Persons); the relevant clearances have not been, and will not be, obtained from the securities commission of any province, territory or jurisdiction of Canada; and no prospectus has been lodged with, or registered by, the Australian Securities and Investments Commission or the Japanese Ministry of Finance. Accordingly, unless an exemption under such act or securities laws is available or unless otherwise determined by AstraZeneca, and permitted by applicable law and regulation, the Loan Notes may not be offered, sold, resold, delivered or transferred, directly or indirectly, in or into the United States, Canada, Australia or Japan or any other jurisdiction if to do so would constitute a violation of the relevant laws of, or require registration thereof in, such jurisdiction or to, or for the account or benefit of, a person located in the United States, Canada, Australia or Japan.

This document includes convenience translations of the consideration to be paid by AstraZeneca from pounds sterling or pence into US dollars. All such amounts have been translated at the exchange rate of £1.00 : $1.8911, the daily noon buying rate for pounds sterling in New York certified by the New York Federal Reserve Bank for customs purposes on 12 May 2006, the last business day prior to the Announcement. Any US dollar amounts actually paid to holders of CAT ADSs will be determined by the tender agent after it converts the pounds sterling proceeds it receives from AstraZeneca into US dollars at the exchange rate obtainable on the spot market in London (net of fees, expenses and withholding taxes, if any) on the date such proceeds are

6






received by the tender agent from AstraZeneca. CAT Shareholders in the United States shall receive all payments in pounds sterling.

To the extent permitted by the City Code, the rules of the UK Listing Authority and the rules of the London Stock Exchange and the Exchange Act, AstraZeneca and its nominees or brokers (acting as agents) may make certain purchases of, or arrangements to purchase, CAT Shares outside the United States during the period in which the Offer remains open for acceptance. Any such purchases will be publicly disclosed in accordance with applicable law in the United Kingdom and the United States.

Forward Looking Statements

This announcement includes certain "forward-looking statements". These statements are based on the current expectations of the management of CAT and AstraZeneca and are naturally subject to uncertainty and changes in circumstances. The forward-looking statements contained herein include statements about the expected effects on AstraZeneca of the Offer, the expected timing and scope of the Offer, and all other statements in this announcement other than historical facts. Forward-looking statements include, without limitation, statements typically containing words such as "intends", "expects", "anticipates", "targets", "estimates" and words of similar import. By their nature, forward-looking statements involve risk and uncertainty because they relate to events and depend on circumstances that will occur in the future. There are a number of factors that could cause actual results and developments to differ materially from those expressed or implied by such forward-looking statements. These factors include, but are not limited to, the satisfaction of the conditions to the Offer, and AstraZeneca's ability successfully to integrate the operations and employees of CAT, as well as additional factors, such as changes in economic conditions, changes in the level of capital investment, success of business and operating initiatives and restructuring objectives, costs associated with research and development, changes in the prospects for products in the research and development pipeline of AstraZeneca or CAT, customers' strategies and stability, changes in the regulatory environment, fluctuations in interest and exchange rates, the outcome of litigation, government actions and natural phenomena such as floods, earthquakes and hurricanes. Other unknown or unpredictable factors could cause actual results to differ materially from those in the forward-looking statements. Neither CAT nor AstraZeneca undertake any obligation to update publicly or revise forward-looking statements, whether as a result of new information, future events or otherwise, except to the extent legally required.

Dealing Disclosure Requirements

Under the provisions of Rule 8.3 of the City Code, if any person is, or becomes, "interested" (directly or indirectly) in 1 per cent. or more of any class of "relevant securities" of CAT, all "dealings" in any "relevant securities" of CAT (including by means of an option in respect of, or a derivative referenced to, any such "relevant securities") must be publicly disclosed by no later than 3.30 p.m. (London time) on the London business day following the date of the relevant transaction. This requirement will continue until the date on which the Offer becomes, or is declared, unconditional as to acceptances, lapses or is otherwise withdrawn or on which the "offer period" otherwise ends. If two or more persons act together pursuant to an agreement or understanding, whether formal or informal, to acquire an “interest" in "relevant securities" of CAT, they will be deemed to be a single person for the purpose of Rule 8.3.

Under the provisions of Rule 8.1 of the City Code, all "dealings" in "relevant securities" of CAT by AstraZeneca or CAT, or by any of their respective "associates", must be disclosed by no later than 12.00 noon (London time) (7.00am New York City time) on the London business day following the date of the relevant transaction.

7






A disclosure table, giving details of the companies in whose "relevant securities" "dealings" should be disclosed, and the number of such securities in issue, can be found on the Panel's website at www.thetakeoverpanel.org.uk.

"Interests in securities" arise, in summary, when a person has long economic exposure, whether conditional or absolute, to changes in the price of securities.

Recommended cash offer

by AstraZeneca UK Limited

for

Cambridge Antibody Technology Group plc

Introduction

The boards of AstraZeneca and CAT announce that they have agreed terms of a recommended cash offer to be made by AstraZeneca to acquire the entire issued and to be issued share capital of CAT not otherwise held by AstraZeneca, either in the form of CAT Shares or CAT ADSs. The terms of the Offer value the existing issued share capital of CAT, excluding AstraZeneca’s existing shareholding in CAT, at approximately £567 million and the entire issued share capital of CAT at approximately £702 million.

Goldman Sachs International is acting as financial adviser to AstraZeneca. Goldman, Sachs & Co. is acting as the dealer manager in the United States for AstraZeneca. Morgan Stanley is acting as financial adviser to CAT.

Summary of the Offer

Under the Offer, which will be subject to the conditions and further terms set out below and in Appendix 1 and the full terms and conditions which will be set out in the Offer Document, CAT Shareholders will be entitled to receive:

for each CAT Share, 1,320 pence in cash

for each CAT ADS, 1,320 pence in cash

The Offer values the entire existing issued share capital of CAT, excluding AstraZeneca’s existing shareholding in CAT, at approximately £567 million and the entire issued share capital of CAT at approximately £702 million.

The Offer represents a premium of approximately 66.9% to the closing mid market price of CAT’s Shares on the London Stock Exchange of 791 pence per share and 68.2% to the closing mid market quotation of CAT’s ADSs on NASDAQ of US$14.84 per ADS, each on 12 May 2006 (being the last dealing day prior to the date of this announcement) and a premium of 88.0% to CAT’s average price of 702 pence per share and a premium of 98.7% to CAT’s average price of US$12.56 per ADS over the last twelve months prior to the date of this announcement. The Offer for each CAT ADS will be 1,320 pence in cash, equivalent to US$24.96 per ADS (based on the exchange rate as at 12 May 2006).

CAT Shares that are subject to the Offer (including those represented by CAT ADSs) will be acquired fully paid with full title guarantee and free from all liens, charges, equitable interests, encumbrances, rights of pre-emption and any other third party rights and interests of any nature whatsoever and together with all rights now and hereafter attaching thereto, including, without limitation, voting rights and the right to receive and retain in full all dividends and other distributions (if any) declared, made or paid on or after the date of this announcement.

A Loan Note Alternative will be made available to all CAT Shareholders (other than any CAT Shareholders in any Restricted Jurisdiction, which includes the United States), further details of which are set out below.

Recommendation

The directors of CAT, who have been so advised by Morgan Stanley, consider the terms of the Offer to be fair and reasonable. In providing its advice, Morgan Stanley has taken into account the commercial assessments of the directors of CAT.

The directors of CAT intend unanimously to recommend that CAT Shareholders accept the Offer, as the directors of CAT have irrevocably undertaken to do in respect of their own beneficial shareholdings.

Irrevocable undertakings

AstraZeneca has received irrevocable undertakings to accept the Offer from each of the directors of CAT, in respect of 190,569 CAT Shares in aggregate, representing approximately 0.36 per cent. of the existing issued share capital of CAT. All of these undertakings will remain binding notwithstanding a higher competing offer.

Further details of these irrevocable undertakings are set out in Appendix 3 to this announcement.

The Loan Note Alternative

As an alternative to all or some of the cash consideration of 1,320 pence per CAT Share, CAT Shareholders (other than any CAT Shareholders in any Restricted Jurisdiction, which includes the United States) who validly accept the Offer will be able to elect to receive Loan Notes issued by AstraZeneca on the following basis:

for each £1 of cash consideration

£1 nominal value of Loan Notes

The Loan Note Alternative will be conditional upon the Offer becoming or being declared unconditional in all respects. The Loan Note Alternative will remain open for acceptance until the Offer closes.

The Loan Notes will be issued by AstraZeneca, credited as fully paid, in amounts and integral multiples of £1 and the balance of any entitlement that is not a whole multiple of £1 will be disregarded and not issued. The Loan Notes will bear interest at 0.75 per cent. below six-month sterling LIBOR to be determined on the first business day of each interest period. Interest will be payable by half-yearly instalments in arrears (less any tax) on 30 June and 31 December in each year. The first payment of interest will be made on the first 30 June or 31 December date which falls more than six months after the date of issue of the Loan Notes (the “First Payment Date”).

On the First Payment Date, interest will be paid in respect of the period from (and including) the date of issue of the relevant Loan Notes to (but excluding) the First Payment Date. The Loan Notes will be redeemable in whole or in part for cash at par at the option of noteholders on the first 30 June or 31 December date which falls more than six months after the date of issue of the Loan Notes and subsequently on each interest payment date.

Unless AstraZeneca decides otherwise, no Loan Notes will be issued by AstraZeneca unless, on or before the date on which the Offer becomes or is declared unconditional in all respects, the aggregate nominal value of all Loan Notes to be issued as a result of valid elections for the Loan Note Alternative exceeds £2,000,000. If such aggregate is less than £2,000,000, any such election shall, unless AstraZeneca decides otherwise, be void and, provided the acceptance of the Offer is

10






otherwise valid, the relevant CAT Shareholders will be deemed to have accepted the Offer for cash. AstraZeneca will have the right to redeem all of the Loan Notes if the aggregate nominal value of outstanding Loan Notes falls below £2,000,000 or if fewer than 25 per cent. of the Loan Notes issued in connection with the Offer remain outstanding at any time during their term. If not previously redeemed, the final redemption date will be 30 June 2011. Any Loan Notes outstanding on the final redemption date will be redeemed at par (together with any accrued interest) on that date. The Loan Notes will not generally be transferable, and no application will be made for them to be listed on, or dealt on, any stock exchange or other trading facility.

The Loan Notes and the Loan Note Instrument constituting them will be governed by and construed in accordance with English law and will be unsecured obligations of AstraZeneca.

Further details of the Loan Notes and the Loan Note Alternative will be contained in the formal Offer Document.

Information relating to CAT

CAT is a biopharmaceutical company, aiming to bring improvements to seriously ill patients' lives through its leading position in the discovery and development of human therapeutic antibodies. CAT has excellent proprietary technology for rapidly isolating human monoclonal antibodies using Phage Display and Ribosome Display systems. CAT has extensive phage antibody libraries, currently incorporating more than 100 billion distinct antibodies. These libraries form the basis for CAT's strategy to develop a portfolio of antibody-based drugs.

CAT seeks to develop products independently and in collaboration with partners. CAT also seeks to licence its technologies to enable others to develop new medicines.

HUMIRA®, licensed to Abbott, is the first CAT-derived human monoclonal antibody to be approved for marketing. It was isolated and optimised in collaboration with Abbott and has been approved for marketing as a treatment for rheumatoid arthritis in 57 countries, and for psoriatic arthritis and early RA in some European countries. HUMIRA® generated $1.4 billion in Abbott reported 2005 revenue.

CAT has three human therapeutic product candidates in clinical development: CAT-354 for severe asthma, GC-1008 for idiopathic pulmonary fibrosis in collaboration with Genzyme and CAT-3888 for a number of B-cell malignancies.

11






There are six CAT-derived human monoclonal antibodies licensed to partners at various stages of clinical development: ABT-874 (Abbott), LymphoStat-B™, HGS-ETR1, HGS-ETR2, ABthrax™ (all Human Genome Sciences) and MYO-029 (Wyeth).

CAT is based near Cambridge, UK, with a new site in Palo Alto, USA and currently employs around 300 people. CAT Shares are listed on the Official List and traded on the London Stock Exchange (GB0001662252) and on NASDAQ (US1321481079).

For the year ended 30 September 2005, in accordance with UK GAAP, CAT reported an operating loss of £9.3 million (2004: operating loss of £42.2 million).

Background to and reasons for the Offer

In late 2004, AstraZeneca and CAT entered into a Collaboration and Licence Agreement jointly to discover and develop human monoclonal antibodies and AstraZeneca acquired a shareholding in CAT that currently represents approximately 19.2 per cent. of the issued share capital.

Building on the success of the collaboration, and recognising the increasing importance of biotechnology in medical research, AstraZeneca is now making this Offer with the aim that CAT will become central to AstraZeneca’s plans to establish a major international presence in the research and development of biological therapeutics. AstraZeneca’s science base already possesses discovery and development capabilities for new biological medicines which will be combined with those of CAT and expanded through further investment. This enhanced research capability, combined with AstraZeneca’s global development, marketing and sales resources, establishes an international platform capable of delivering new medicines in AstraZeneca’s prioritised disease areas, embracing both monoclonal antibodies and novel biological entities, at a more rapid pace than could be achieved through the existing alliance. CAT has a number of licensing agreements in place and AstraZeneca intends to honour all existing licensing agreements following the Offer.

CAT’s capabilities, when combined with AstraZeneca’s global development and marketing expertise, will deliver an expanded pipeline of novel biological therapeutics to address unmet medical needs of patients in AstraZeneca’s targeted disease areas. AstraZeneca’s ability to bring additional resources and capabilities to CAT will allow it to develop CAT’s technology platform beyond its current capability and across a number of therapeutic areas including Respiratory & Inflammation, Oncology & Infection, Neuroscience, Cardiovascular and Gastro-intestinal. CAT also provides AstraZeneca with several other substantial assets beyond its current scientific capabilities. These include a royalty stream on the sales of HUMIRA®, potential milestones and royalties on CAT’s other licensed products and access to CAT’s proprietary pipeline (including CAT-3888 in Phase II and CAT-354 in Phase I), which will be integrated into AstraZeneca’s development portfolio. In addition, CAT had a balance of net cash and liquid resources of approximately £152 million as at 31 December 2005.

AstraZeneca now intends to create a major R&D capability to deliver biological therapeutics, and the integration of CAT is central to these plans. The new organisation will be led from CAT’s Cambridge headquarters and will be distinct from but complementary to AstraZeneca’s small molecule capability.

Management and employees of CAT

Part of the rationale for the Offer is the value that AstraZeneca places on the skills, expertise and experience of existing management and employees of CAT. In recognition of this, AstraZeneca will procure that the employees of CAT at the time the Offer closes will, provided they remain in CAT's employment on the first anniversary of closing and have not resigned or been dismissed by reason of serious misconduct before that date, receive a special retention payment. AstraZeneca has

12






given the board of CAT assurances that, following the closing of the Offer, the existing employment rights, including pension rights, of all management and employees of CAT will be fully safeguarded. AstraZeneca’s plans for CAT do not involve any material change in the conditions of employment of CAT employees. AstraZeneca has no plans to change the location of CAT's places of business. It has been agreed in principle that Peter Chambré, the Chief Executive Officer of CAT, will leave CAT following the Offer becoming unconditional in all respects and having participated in planning for the successful combination of CAT and AstraZeneca.

CAT Share Schemes

The Offer will extend to any CAT Shares unconditionally allotted or issued pursuant to the CAT Share Schemes while the Offer remains open for acceptance (or such earlier date as AstraZeneca may, subject to the rules of the Code, decide). Appropriate proposals will be made to participants in CAT Share Schemes in due course.

Financing

AstraZeneca will fund the Offer entirely out of current cash balances. Goldman Sachs International, financial adviser to AstraZeneca, is satisfied that sufficient resources are available to satisfy in full the cash consideration payable to CAT Shareholders under the terms of the Offer.

Exclusivity and co-operation

CAT has entered into an exclusivity agreement in customary terms with AstraZeneca for the duration of the Offer. In addition, the parties have entered into a co-operation agreement in connection with the implementation of the Offer.

Break fees

CAT has agreed to pay a sum to AstraZeneca of £5,000,000 if either (i) the directors of CAT change the terms of or withdraw their recommendation of the Offer or (ii) before the Offer lapses or is withdrawn without becoming or being declared wholly unconditional any person (other than AstraZeneca or a person acting in concert (as defined in the City Code) with AstraZeneca) announces an intention to make a competing offer however effected, to acquire the entire issued share capital of CAT (other than CAT Shares owned by such third party or persons acting in concert with it) and, at any time, the competing offer becomes or is declared wholly unconditional. AstraZeneca has agreed to pay a sum to CAT of £2,500,000 if AstraZeneca invokes the OFT Condition or if the Offer lapses by reason of the referral of the Offer by the OFT to the Competition Commission, unless the failure to satisfy the OFT Condition, or the referral to the Competition Commission, as appropriate, arises from the failure of CAT to use its reasonable endeavours to assist in the satisfaction of the OFT Condition (including the provision of necessary information or assistance to the OFT).

Disclosure of interests in CAT Shares

On 21 November 2004, AstraZeneca entered into an agreement (the "Subscription Agreement") with CAT pursuant to which AstraZeneca agreed to subscribe for a total of 10,217,983 ordinary shares of 10p each (the "Subscription Shares") in CAT. The Subscription Agreement and the corresponding subscription for the Subscription Shares were completed on 17 December 2004. The Subscription Shares currently represent approximately 19.2 per cent. of CAT’s issued share capital.

Under the terms of the Subscription Agreement AstraZeneca agreed, for a period of 36 months from 21 November 2004, not to acquire or own any interests in shares (as defined in section 208 of the Companies Act) in CAT in addition to the Subscription Shares if, as a result of such acquisition, the percentage of CAT's issued ordinary share capital held by AstraZeneca and its

13






Affiliates (as such term is defined in the Subscription Agreement) would exceed 19.907 per cent. of CAT's issued ordinary share capital. AstraZeneca also agreed, for a period of 36 months from 21 November 2004, not to make an offer to acquire any shares in the capital of CAT under the Code unless such offer was recommended by a majority of the CAT Directors. CAT released AstraZeneca from these obligations on 14 May 2006 to facilitate the making of the proposed Offer.

Save as set out above and save for 261,064 CAT Shares held as at 10 May 2006 by affiliates of Goldman Sachs International (who are acting in concert (within the meaning of the City Code) with AstraZeneca), as at 14 May 2006, the last practicable date prior to this announcement, neither AstraZeneca nor, so far as AstraZeneca is aware, any person acting in concert with AstraZeneca had an interest in or right to subscribe for relevant securities of CAT or had any short position in relation to the relevant securities of CAT (whether conditional or absolute and whether in the money or otherwise), including any short position under a derivative, any agreement to sell or any delivery obligation or right to require another person to purchase or take delivery of any relevant securities of CAT.

Delisting, cancellation of trading, compulsory acquisition and re-registration

If the Offer becomes or is declared unconditional in all respects, and sufficient acceptances under the Offer are received, AstraZeneca intends to procure that CAT make applications to cancel the listing of CAT Shares from the UKLA’s Official List and to cancel admission to trading in CAT Shares on the London Stock Exchange's market for listed securities. AstraZeneca also intends to procure that CAT applies for delisting of the CAT ADSs from NASDAQ. Such de-listings would significantly reduce the liquidity and marketability of any CAT Shares or CAT ADSs not assented to the Offer at that time. AstraZeneca may also request that CAT terminate the existing deposit agreement through which the ADS programme is operated.

In addition, if the number of holders of CAT Securities in the United States falls below 300 (calculated in accordance with Rule 12g3-2(a) under the Exchange Act), AstraZeneca intends to procure that CAT file a Form 15 with the SEC to request that its reporting obligations under the Exchange Act are terminated or suspended.

If AstraZeneca receives acceptances under the Offer in respect of, or otherwise acquires, 90 per cent. or more of CAT Shares to which the Offer relates, AstraZeneca intends to exercise its rights pursuant to the provisions of sections 428 to 430F (inclusive) of the Act, or Schedule 2 of the Interim Regulations, as applicable, to acquire compulsorily the remaining CAT Shares in respect of which the Offer has not been accepted on the same terms as the Offer.

It is anticipated that cancellation of listing on the Official List and of admission to trading on the London Stock Exchange will take effect no earlier than 20 business days after either (i) the date on which AstraZeneca has, by virtue of its shareholdings and acceptances of the Offer, acquired or agreed to acquire issued share capital carrying 75 per cent. of the voting rights of CAT or (ii) the first date of issue of compulsory acquisition notices under section 429 of the Act, or Schedule 2 of the Interim Regulations, as applicable. AstraZeneca will notify CAT Shareholders when the required 75 per cent. has been attained and confirm that the notice period has commenced and the anticipated date of cancellation.

It is also intended that, following the Offer becoming or being declared unconditional, CAT will be re-registered as a private company under the relevant provisions of the Act.

Unless otherwise determined by AstraZeneca or required by the City Code, and permitted by applicable law and regulation, the Offer, including the Loan Note Alternative, will not be made, directly or indirectly, in, into or from, and will not be capable of acceptance in or from Canada or Japan or any jurisdiction where to do so would constitute a breach of securities laws in that jurisdiction.

Any US dollar amounts actually paid to holders of CAT ADSs will be determined by the tender agent after it converts the pounds sterling proceeds it receives from AstraZeneca into US dollars at the exchange rate obtainable on the spot market in London (net of fees, expenses and withholding taxes, if any) on the date such proceeds are received by the tender agent from AstraZeneca. CAT Shareholders in the United States shall receive all payments in pounds sterling.

To the extent permitted by the City Code, the rules of the UK Listing Authority and the rules of the London Stock Exchange and the Exchange Act, AstraZeneca and its nominees or brokers (acting as agents) may make certain purchases of, or arrangements to purchase, CAT Shares outside the United States during the period in which the Offer remains open for acceptance. Any such purchases will be publicly disclosed in accordance with applicable law in the United Kingdom and the United States.

Forward Looking Statements

This announcement includes certain "forward-looking statements". These statements are based on the current expectations of the management of CAT and AstraZeneca and are naturally subject to uncertainty and changes in circumstances. The forward-looking statements contained herein include statements about the expected effects on AstraZeneca of the Offer, the expected timing and scope of the Offer, and all other statements in this announcement other than historical facts. Forward-looking statements include, without limitation, statements typically containing words such

18






as "intends", "expects", "anticipates", "targets", "estimates" and words of similar import. By their nature, forward-looking statements involve risk and uncertainty because they relate to events and depend on circumstances that will occur in the future. There are a number of factors that could cause actual results and developments to differ materially from those expressed or implied by such forward-looking statements. These factors include, but are not limited to, the satisfaction of the conditions to the Offer, and AstraZeneca's ability successfully to integrate the operations and employees of CAT, as well as additional factors, such as changes in economic conditions, changes in the level of capital investment, success of business and operating initiatives and restructuring objectives, costs associated with research and development, changes in the prospects for products in the research and development pipeline of AstraZeneca or CAT, customers' strategies and stability, changes in the regulatory environment, fluctuations in interest and exchange rates, the outcome of litigation, government actions and natural phenomena such as floods, earthquakes and hurricanes. Other unknown or unpredictable factors could cause actual results to differ materially from those in the forward-looking statements. Neither CAT nor AstraZeneca undertake any obligation to update publicly or revise forward-looking statements, whether as a result of new information, future events or otherwise, except to the extent legally required.

Dealing disclosure requirements

Under the provisions of Rule 8.3 of the City Code, if any person is, or becomes, "interested" (directly or indirectly) in 1 per cent. or more of any class of "relevant securities" of CAT, all "dealings" in any "relevant securities" of CAT (including by means of an option in respect of, or a derivative referenced to, any such "relevant securities") must be publicly disclosed by no later than 3.30 p.m. (London time) on the London business day following the date of the relevant transaction. This requirement will continue until the date on which the Offer becomes, or is declared, unconditional as to acceptances, lapses or is otherwise withdrawn or on which the "offer period" otherwise ends. If two or more persons act together pursuant to an agreement or understanding, whether formal or informal, to acquire an “interest" in "relevant securities" of CAT, they will be deemed to be a single person for the purpose of Rule 8.3.

Under the provisions of Rule 8.1 of the City Code, all "dealings" in "relevant securities" of CAT by AstraZeneca or CAT, or by any of their respective "associates", must be disclosed by no later than 12.00 noon (London time) (7.00am New York City time) on the London business day following the date of the relevant transaction.

A disclosure table, giving details of the companies in whose "relevant securities" "dealings" should be disclosed, and the number of such securities in issue, can be found on the Panel's website at www.thetakeoverpanel.org.uk.

"Interests in securities" arise, in summary, when a person has long economic exposure, whether conditional or absolute, to changes in the price of securities.

AstraZeneca shall be under no obligation

26






to waive (if capable of waiver), to determine to be or remain satisfied or to treat as fulfilled any of conditions 2 to 10 (inclusive) by a date earlier than the latest date for the fulfilment of that condition notwithstanding that the other conditions of the Offer may at such earlier date have been waived or fulfilled and that there are at such earlier date no circumstances indicating that any of such conditions may not be capable of fulfilment.

The Offer will lapse (unless otherwise agreed with the Panel) if, before the later of the first closing date of the Offer and the date when the Offer becomes or is declared unconditional as to acceptances:

(i)      the OFT has referred the Offer to the Competition Commission; or

(ii)     the European Commission has initiated proceedings under Article 6(1)(c) of the Regulation.

Item 16

Dealing by Directors
Companies Act 1985 Sections 324/329

We hereby inform you that, on 19 May 2006, David R Brennan, a Director of AstraZeneca PLC, was granted an option under the AstraZeneca Share Option Plan over the Company’s USD0.25 Ordinary Shares as follows.

Number of shares over   Exercise price   Period when   Total number of  
which option is granted   per share   exercisable   shares under option  
               
22,910   2848p   19.5.09-18.5.16   See below  

The option will become exercisable on 19 May 2009 subject to certain performance conditions. The conditions, which will not be subject to any retesting, are that the earnings per share of the Company must increase by the increase in the UK Retail Prices Index plus 5% per annum on average over three years, and that no significant unforeseen event has taken place which, in the reasonable opinion of the Remuneration Committee, has resulted in major reputational damage to AstraZeneca, and the circumstances of which are exceptional enough to justify the option not vesting and becoming exercisable. Failure to satisfy either or both of these conditions will result in the lapse of the option in its entirety.

Mr Brennan has previously received grants of options over the Company’s American Depositary Shares (ADSs). One ADS equals one Ordinary Share. Following the grant of options referred to above, David Brennan has options over 110,641 Ordinary Shares and 440,643 ADSs.

We also inform you that on 19 May 2006 David R Brennan, a Director of AstraZeneca PLC, was granted an award under the terms of the AstraZeneca Performance Share Plan over the Company’s USD0.25 Ordinary Shares as follows.

Target number of   Award price   Normal vesting   Total interest in shares   Percentage of  
shares awarded   per share   date   after this award   shares in issue  
                   
19,092   2848p   19 May 2009   See below   See below  

The AstraZeneca Performance Share Plan was approved by shareholders at the Company’s AGM in 2005. Awards made under the Plan may not generally vest before the third anniversary of the relevant date of grant nor unless the specified performance target(s) have been met at the end of the three year period which, for this award, is 1 January 2006 to 31 December 2008.

The performance target that applies to this award is the Company’s Total Shareholder Return (“TSR”) compared to the TSR of a selected peer group of 12 other pharmaceutical companies. The actual number of shares to which a participant may become unconditionally entitled will depend on the extent to which the performance target(s) have been met. A summary of the Plan, including a more detailed explanation of the performance target(s), can be found in the AstraZeneca Annual Report and Form 20-F Information 2005 which is available on the Company’s website www.astrazeneca.com.

Mr Brennan has interests in both the Company’s Ordinary Shares and American Depositary Shares (ADSs). One ADS equals one Ordinary Share. Following the award of Ordinary Shares referred to above, Mr Brennan now has an interest in 98,553 Ordinary Shares and 167,453 ADSs, which together represent approximately 0.017% of the number of shares currently in issue.
