Application of the Safe Harbor of the US Private Securities Litigation Reform Act of 1995: This document contains certain statements about CAT or OGS that are or may be forward-looking. All statements other than statements of historical facts included in this document may be forward-looking statements. Any statements preceded or followed by or that include the words "targets", "plans", "believes", "expects", "aims", "intends", "will", "may", "anticipates" or similar expressions or the negative thereof are forward-looking statements. Forward-looking statements include statements relating to the following:(i) future capital expenditures, expenses, revenues, economic performance, financial condition, dividend policy, losses and future prospects; (ii) future performance in clinical trials of the product candidates that were developed using CAT's or OGS' technology; (iii) the ability of CAT or OGS and their respective collaborators to commercialise products; (iv) business and management strategies and the expansion and growth of CAT's or OGS' operations; (v) the effects of government regulation on CAT's or OGS' businesses; (vi) expansion and other development trends of CAT's or OGS' current and future customers and their industries; (vii) acquisitions, including the timing, nature, availability, location and significance of those acquisitions; (viii) costs relating to the integration of the businesses of CAT and OGS; and (ix) cost savings from the Merger. These forward-looking statements involve known and unknown risks, uncertainties and other factors that may cause the actual results, performance or achievements of CAT or OGS or industry results, to be materially different from any future results, performance or achievements expressed or implied by such forward-looking statements. These forward-looking statements are based on numerous assumptions regarding CAT's and/or OGS' present and future business strategies and the environment in which CAT and OGS will operate in the future. Certain factors that could cause CAT's or OGS' actual results, performance or achievements to differ materially from those in the forward-looking statements are described in the `Risk factors' in Part VIII of the Listing Particulars. The expected operating cost savings have been calculated on the basis of the existing cost and operating structures of the companies and by reference to current prices and the current regulatory environment. These statements of estimated cost savings and one-off costs for achieving them relate to future actions and circumstances which, by their nature, involve risks, uncertainties and other factors. As a result, the cost savings referred to may not be achieved, or those achieved could be materially different from those estimated.

PART I JOINT LETTER FROM THE CHAIRMEN OF OXFORD GLYCOSCIENCES PLC AND CAMBRIDGE ANTIBODY TECHNOLOGY GROUP PLC Oxford Glycosciences Plc CAT The Forum Milstein Building 86 Milton Park Granta Park Abingdon Cambridge CB1 6GH Registered number: 03234033 Oxfordshire OX14 4RY Registered number: 2723527 6 February 2003 To OGS Shareholders, OGS ADS holders and, for information only, participants in the OGS Share Option Schemes Dear Shareholder, Recommended Merger of Oxford GlycoSciences Plc and Cambridge Antibody Technology Group plc On 23 January 2003, the Boards of OGS and CAT announced that they had agreed the terms of a recommended merger+. We are delighted that we are now able to write to you with full details of the Merger. Rationale for the Merger The Merger will create an enlarged entity with greater scientific, organisational and financial resources. In particular: o the Enlarged Group will have a stronger and broader portfolio, with two approved products, seven additional product candidates in clinical trials and seven pre-clinical products; o the Merger will significantly strengthen the Enlarged Group's core capabilities in research and development by combining CAT's leading human monoclonal antibody product development expertise with OGS' oncology drug discovery capabilities and potential target pool and by increasing the breadth of the discovery and pre-clinical portfolios; o the Enlarged Group will have substantially greater financial strength. This will increase its ability to fund product development to later stages, thereby retaining greater value, and reducing the need for additional capital. Pro-forma net cash was (pound)260.1 million as at 31 December 2002; and o cost savings based on the removal of duplicated activities have been identified in the areas of corporate overhead, R&D and real estate. These savings are expected to have a cash effect of approximately (pound)10 million in the first full financial year following completion of the Merger*. In addition, further savings are expected from a portfolio review to focus R&D expenditure in the highest quality projects. The results of this review will be announced in November 2003. The Merger, which is being effected by way of a scheme of arrangement of OGS under section 425 of the Companies Act and which is expected to become effective by 31 March 2003, is subject to the satisfaction of a number of conditions, all of which are set out in Part IV of this document. These conditions include the approval of the Merger by both OGS Shareholders and CAT Shareholders, the obtaining of relevant regulatory consents and the sanction of the Scheme by the Court. The Merger has the support and recommendation of both the OGS Board+ and CAT Board.

Kirk Raab Professor Peter Garland Chairman Chairman Oxford GlycoSciences Plc Cambridge Antibody Technology Group plc + Dr Donald Drakeman, an OGS Director, is also the Chief Executive Officer of Medarex, Inc., a competitor of CAT and has, therefore, not participated in decisions of the OGS Board relating to the Merger. Accordingly, he has abstained from the recommendation by the OGS Board to OGS Shareholders and from entering into any undertakings regarding voting in favour of the resolutions to be presented at the OGS Court Meeting and the OGS EGM which are required to implement the Merger. All references in this document to the recommendation of the OGS Board should be read accordingly. * The expected operating cost savings have been calculated on the basis of the existing cost and operating structures of the companies and by reference to current prices and the current regulatory environment. These statements of estimated cost savings and one-off costs for achieving them relate to future actions and circumstances which, by their nature, involve risks, uncertainties and other factors. As a result, the cost savings referred to may not be achieved, or those achieved could be materially different from those estimated. PART II LETTER FROM THE CHAIRMAN OF OXFORD GLYCOSCIENCES PLC The Forum 86 Milton Park Abingdon Oxfordshire OX14 4RY Registered number: 2723527 6 February 2003 To OGS Shareholders, OGS ADS holders and, for information only, participants in the OGS Share Option Schemes Dear Shareholder, Recommended Merger of Oxford GlycoSciences Plc and Cambridge Antibody Technology Group plc 1. Introduction On 23 January 2003, the Boards of OGS and CAT announced that they had agreed the terms of a recommended merger+. I am writing to you today to set out the terms of the Merger of OGS and CAT, to explain the background to and reasons for our recommendation of the Merger and to seek your support and approval for the Merger. In order to approve the terms of the Merger, OGS Shareholders will need to vote in favour of the resolutions to be proposed at two shareholders' meetings (the OGS Court Meeting and the OGS EGM) to be held on 11 March 2003. The actions you should take, and the recommendation of the OGS Directors, are set out in paragraphs 10 and 11, respectively, of this letter. This document should be read in conjunction with the accompanying Listing Particulars which contain further information on OGS, CAT and the Enlarged Group. The Merger is being supported and recommended by your Directors+ and it has also received the support and recommendation of the CAT Directors. A document addressed to CAT Shareholders seeking their approval for the Merger is also being posted today. Pro-forma financial information on the Enlarged Group, including the basis on which it has been prepared, is set out in Part IV of the Listing Particulars. Financial information relating to OGS for the financial years ended 31 December 1999, 2000 and 2001 and the unaudited interim results to 30 June 2002 are set out in Part III of the Listing Particulars. Financial information relating to CAT for the financial years ended 30 September 2000, 2001 and 2002 is set out in Part II of the Listing Particulars. 2. Summary terms of the Merger The Merger of CAT and OGS will be effected by way of a scheme of arrangement of OGS under section 425 of the Companies Act. Under the terms of the Merger, CAT Shareholders will retain their shares in CAT and, upon completion of the Merger, OGS Shareholders will receive: for each OGS Share 0.3620 New CAT Shares OGS ADS holders will receive New CAT ADSs on the following basis: for each OGS ADS 0.3620 New CAT ADSs Based upon CAT's share price of 540.0 pence, being the Closing Price of a CAT Share on 22 January 2003, (which was the last Business Day prior to the date of the announcement of the Merger), the Merger values each OGS Share at 195.5 pence, and the entire issued and to be issued share capital of OGS at approximately (pound)109.6 million. This represents a premium of 28.2 per cent. over the Closing Price on 22 January 2003 (which was the last Business Day prior to the date of the announcement of the Merger) of 152.5 pence per OGS Share. Based on the volume weighted average trading price of CAT Shares in the last ten Business Days prior to the date of the announcement of the Merger, the Merger values each OGS Share at 210.6 pence and the entire issued and to be issued share capital of OGS at approximately (pound)118.2 million. This represents a premium of 43.3 per cent. over the volume weighted average trading price of OGS Shares in the last ten Business Days prior to the date of the announcement of the Merger of 147.0 pence per OGS Share. Based upon CAT's share price of 464.0 pence, being the Closing Price of a CAT Share on 4 February 2003 (being the last practicable date prior to the publication of this document), the Merger values each OGS Share at 168.0 pence, and the entire issued and to be issued share capital of OGS at approximately (pound)93.9 million. This represents a premium of 10.1 per cent. over the Closing Price of 152.5 pence per OGS Share on 22 January 2003 (which was the last Business Day prior to the date of the announcement of the Merger). Upon completion of the Merger, which is expected to occur by 31 March 2003, and based on the issued share capital of each company on 23 January 2003, being the date of announcement of the Merger, CAT Shareholders will hold approximately 64.3 per cent. and OGS Shareholders will hold approximately 35.7 per cent. of the issued share capital of CAT. The name of CAT will be changed in due course as part of the management's commitment to building a leading biopharmaceutical company. The New CAT Shares issued pursuant to the Merger will be issued credited as fully paid and will rank pari passu in all respects with the Existing CAT Shares. The consideration for each OGS ADS will be received by the ADS Depositary according to the terms and conditions of the Deposit Agreement. The Deposit Agreement will be amended as of the Effective Date to be identical to the CAT Deposit Agreement. Part VII of the Listing Particulars contains a summary of certain of the terms of the CAT Deposit Agreement which will be applicable to holders of OGS ADSs after the Effective Date. It is expected that, once the ADS Depositary has been issued with the underlying New CAT Shares, holders of OGS ADSs will receive their New CAT ADSs from the ADS Depositary upon surrender of their OGS ADSs in accordance with the terms of the Deposit Agreement as amended. CAT Shares will continue to be listed on the London Stock Exchange. Its ADSs will also continue to trade on NASDAQ. The Merger will be effected by way of a scheme of arrangement of OGS under section 425 of the Companies Act. The Scheme is subject to the conditions and further terms set in Part IV of this document. It is anticipated that, subject to the satisfaction of these conditions, the Merger will be completed by 31 March 2003. Unless the Scheme becomes effective by no later than 30 April 2003, or such later date, if any, as OGSand CAT may agree and the Court may allow, the Merger will not proceed. 3. Background to and reasons for the Merger CAT has stated that its goal is to complete the transition to a profitable, product-based biopharmaceutical company over the next five years and to build a broad portfolio of products that will deliver rapid revenue and profit growth beyond that point through a combination of internal development and acquisition. OGS has stated that its goals are to focus on key objectives including cost reductions and to build critical mass and strengthen its clinical pipeline through appropriate transactions. The Merger helps both companies to achieve their stated goals by creating an enlarged entity which will significantly strengthen discovery and development capabilities and the financial resources with which to build its pipeline. In particular: o the Merger will significantly strengthen the Enlarged Group's core capabilities in R&D by combining CAT's leading human monoclonal antibody product development expertise with OGS' oncology drug discovery capabilities and potential target pool and by increasing the breadth of the discovery and pre-clinical portfolios. The Enlarged Group will also have both antibody and small molecule discovery capabilities, as well as significantly improved scale in product development resulting from the combination of each Group's strengths in pre-clinical, clinical and regulatory activities. The Enlarged Group will benefit from OGS' demonstrated ability to drive products through to approval; and o the Enlarged Group will have a stronger and broader portfolio, with two approved products, seven additional product candidates in clinical trials and seven pre-clinical products. These are set out below:
Product/Candidate Partner Disease Phase ------------------------------------------------------------------------------------------------------------------ Humira(TM) Abbott Rheumatoid arthritis(1) Approved in US; filed for approval in Europe Juvenile rheumatoid arthritis Phase III Crohn's disease Phase II/III Zavesca(TM) Actelion/Teva Type I Gaucher disease(2) Approved in Europe; filed in Israel and an amended application to be filed in the US CAT-152 -- Scarring post glaucoma surgery Phase III CAT-192 Genzyme Scleroderma Phase I/II CAT-213 -- Allergic disorders Phase I/II J695 Abbott/Wyeth Rheumatoid arthritis Phase II Crohn's disease Phase II LymphoStat-B(TM) HGSI Systemic lupus erythematosus Phase I TRAIL-R1 mAb HGSI Cancer Phase I OGT 923 -- Glycolipid disorders Phase I GC1008 Genzyme Fibrotic diseases Pre-clinical OGT 2378 -- Cancer Pre-clinical TRAIL-R2 mAb HGSI Cancer Pre-clinical MDX-OGS 001 Medarex Cancer Pre-clinical Undisclosed Wyeth Undisclosed Pre-clinical Undisclosed HGSI Undisclosed Pre-clinical Undisclosed Undisclosed Undisclosed Pre-clinical
(1) Also in development for psoriasis, psoriatic arthropathy and ankylosing spondylitis (2) Also in development for Niemann-Pick Type C, Late-Onset Tay Sachs and Type III Gaucher disease o The Enlarged Group will have substantially greater financial strength. This will increase its ability to fund product development to later stages, thereby retaining greater value and reducing the need for additional capital. Pro-forma net cash was (pound)260.1 million as at 31 December 2002; and o Cost savings based on the removal of duplicated activities have been identified in the areas of corporate overhead, R&D and real estate. These savings are expected to have a cash effect of approximately (pound)10 million in the first full financial year following completion of the Merger*. In addition, further savings are expected from a portfolio review to focus R&D expenditure on the highest quality projects. The results of this review will be announced in November 2003. 4.

Additional revenues may arise from technical and clinical milestone payments and any further licensing or contract research arrangements, including extensions to existing arrangements. Cash receipts from collaborators and licensees in the 2003 financial year are expected to be at least comparable to the 2002 financial year. On 31 December 2002, Abbott Laboratories announced that it had received FDA approval to market Humira for the treatment of rheumatoid arthritis in the US. This approval was received earlier than had been expected and Abbott has stated that it began supplying Humira to pharmacies throughout the US in January 2003. The European Agency for the Evaluation of Medicinal Products ("EMEA") accepted Abbott's submission for Humira for the treatment of rheumatoid arthritis in April 2002, and approval is expected by Abbott in mid-2003. Humira was developed in a collaboration between Abbott and CAT, under which CAT will receive milestone payments based upon approval in the US and Europe and royalties based on Humira sales. Significant increases in operating costs are expected during the current financial year as compared with the 2002 financial year. This reflects, in particular, an increase in spending on clinical trials on CAT's pipeline of product candidates. In December 2002, CAT settled patent disputes with MorphoSys and Crucell and announced a cross-licensing arrangement with Xoma. In January 2003, CAT announced an expanded licence agreement with Dyax as referred to in paragraph 6 of Part I of the accompanying Listing Particulars. As at 31 December 2002, CAT had net cash and liquid resources of approximately (pound)123.7 million, representing 340.2 pence per CAT ordinary share in issue. OGS' current trading In September 2002, OGS announced a reorganisation of its operations and a cost reduction programme. In light of the delays in the approval of Zavesca in the US, the Bridgewater, New Jersey facility was closed. OGS also carried out a review of its UK operations which resulted in redundancies, restructuring and the streamlining of some existing alliances. As from 1 January 2003, OGS has been reorganised into three separate business units: ISD, proteomics and oncology, with the intention of increasing transparency, responsibility and accountability. In November 2002, OGS announced that the European Commission had granted marketing authorisation for Zavesca, an oral treatment for patients with mild to moderate Type I Gaucher disease for whom enzyme replacement therapy is unsuitable. The existing European marketing agreement with Actelion for Zavesca was also extended to cover the rest of the world, excluding Israel. Zavesca is expected to be launched in Europe in March 2003. In January 2003, Zavesca was filed for approval in Israel by Teva, which has rights to the drug in Israel. Following recent discussions with the FDA, OGS and Actelion intend to submit an amendment to the New Drug Application for Zavesca in the first quarter of 2003. In addition to the US, Actelion intends to file for registration of Zavesca in Japan and will evaluate opportunities in other territories, as appropriate. OGS has also commenced a Phase I study with OGT 923, bringing a second iminosugar into clinical development for glycosphingolipid storage disorders. As at 31 December 2002, the OGS Group had net cash of approximately (pound)136.4 million, representing 244.8 pence per OGS ordinary share in issue. Prospects for the Enlarged Group As detailed in the above section, Abbott Laboratories received FDA approval on 31 December 2002 to market Humira for the treatment of rheumatoid arthritis in the US, and in November 2002 OGS announced that the European Commission had granted marketing authorisation for Zavesca. Cost savings based on the removal of duplicated activities have been identified in the areas of corporate overhead, R&D and real estate. These savings are expected to have a cash effect of approximately (pound)10 million in the first full financial year following completion of the Merger*. In addition, further savings are expected from a portfolio review to focus R&D expenditure on the highest quality projects. The results of this review will be announced in November 2003. One-off costs relating to the integration of CAT and OGS are expected to be up to (pound)6 million. Management intends to continue OGS' business unit strategy in respect of proteomics and ISD. The Enlarged Group will have substantially greater financial strength. This will increase its ability to fund product development to later stages, thereby retaining greater value and reducing the need for additional capital. Pro-forma net cash was (pound)260.1 million as at 31 December 2002. The Merger helps both companies to achieve their stated goals by creating an enlarged entity with significantly strengthened discovery and development capabilities and financial resources with which to build its pipeline. The CAT Directors are confident of the prospects for the Enlarged Group. 8. Year-end It is intended that, following completion of the Merger, the accounting reference date for CAT will remain unchanged as 30 September. The first audited financial statements of the Enlarged Group will be for the period to 30 September 2003. 9. Dividend policy Neither CAT nor OGS have paid dividends on their ordinary shares and CAT does not plan to pay dividends on the CAT Shares in the foreseeable future. 10. Action to be taken We are seeking your approval of the Merger and the Scheme (together, the "Proposals") at a meeting convened by order of the Court, described as the OGS Court Meeting, and at the related OGS EGM. These meetings are to be held at the offices of Financial Dynamics, Holborn Gate, 26 Southampton Buildings, London, WC2A 1PB at 10.00 a.m. and at 10.15 a.m. (or, if later, immediately after the conclusion or adjournment of the previous meeting) respectively on 11 March 2003. Whilst you do not have to attend the meetings to vote on the Proposals, your support is important to us. Therefore, I encourage you to vote on the Proposals by completing, signing and returning the enclosed Forms of Proxy whether or not you intend to attend and vote in person. If you are a holder of OGS ADSs, you may only vote in person at the OGS Court Meeting and/or the OGS EGM if you become a registered holder of OGS Shares by arranging for the surrender of your OGS ADSs in accordance with the terms and conditions of the Deposit Agreement. Please contact The Bank of New York, the ADS Depositary, on the US telephone number +1 (212) 815 2783 for further information on surrendering your OGS ADSs. Alternatively, you may instruct The Bank of New York, as ADS Depositary, how to vote the OGS Shares underlying your OGS ADSs at the OGS Court Meeting and/or OGS EGM. A voting instruction card is enclosed for this purpose and must be completed, signed and returned to the ADS Depositary so that the ADS Depositary receives it no later than 5.00 p.m. (New York time) on 4 March 2003. In respect of the OGS EGM only, if the voting instruction card is signed and returned but no instructions are indicated in the appropriate box, or if the voting instruction card is not signed and returned, or if the voting instruction card is not returned, a discretionary proxy will be given to the chairman of the OGS EGM to vote the relevant OGS ADSs. If you hold your OGS ADSs indirectly, you must rely on the procedures of your bank, broker or financial institution through which you hold your OGS ADSs. If you have any other questions about this document or the other documents contained in this mailing or about any other matter related to the Merger, please call OGS' Registrars, Lloyds TSB Registrars, on +44 (0)870 600 3953 or +44 (0)121 415 7047 between 9.00 a.m. and 5.00 p.m. Monday to Friday (from the date of this document until 10 March 2003). For legal reasons, this helpline will not be able to provide advice on the merits of the Merger itself or give financial advice. Your attention is drawn to the letter from Goldman Sachs set out in Part III of this document which gives further details of the Merger and the Scheme which will implement it. 11. Recommendation The OGS Directors (other than Dr Drakeman)+, who have been so advised by Goldman Sachs, consider the terms of the Proposals to be fair and reasonable. In providing their financial advice, Goldman Sachs has taken into account the OGS Directors' commercial assessments. The OGS Directors believe the Proposals to be in the best interests of OGS Shareholders taken as a whole. Accordingly, the OGS Directors recommend that OGS Shareholders vote in favour of the resolutions to be proposed at the OGS Court Meeting and the OGS EGM, as they intend to do in respect of their own respective beneficial holdings which on 4 February 2003 (the last practicable date prior to the publication of this document) amounted to, in aggregate, 273,873 OGS Shares representing approximately 0.5 per cent. of the issued ordinary share capital of OGS. Yours sincerely, Kirk Raab Chairman Oxford GlycoSciences Plc PART III EXPLANATORY STATEMENT FROM OGS' FINANCIAL ADVISERS Goldman Sachs International (registered in England and Wales under number 2263951) Registered office Peterborough Court 133 Fleet Street London EC4A 2BB 6 February 2003 To OGS Shareholders, OGS ADS holders and, for information only, participants in the OGS Share Option Schemes Dear Sir/Madam, Recommended Merger of Oxford GlycoSciences Plc and Cambridge Antibody Technology Group plc 1. Introduction On 23 January 2003, the OGS and CAT Boards announced that they had agreed the terms of a recommended merger+. The OGS Directors have been advised by Goldman Sachs in connection with the Merger. We have been authorised by the OGS Directors to write to you to explain the terms of the Merger and to provide you with other relevant information. Your attention is drawn in particular to: o the joint letter from the Chairmen of OGS and CAT set out in Part I of this document; and o the letter from the Chairman of OGS set out in Part II of this document. Those letters form part of this explanatory statement and contain, amongst other things, information on the reasons for the Merger and the recommendation by the OGS Board to OGS Shareholders to vote in favour of the resolutions to be proposed at the OGS Court Meeting and the OGS EGM. Your attention is also drawn to the other parts of this document, which all form part of this explanatory statement. The CAT Directors have also recommended CAT Shareholders to vote in favour of the resolution to be proposed at an extraordinary general meeting of CAT to approve the Merger. If you are also a CAT Shareholder you will receive or will have received separate instructions as to what action you should take in respect of that holding. 2. Summary of the terms of the Merger The Merger of CAT and OGS will be implemented by way of a Scheme of Arrangement to be effected by OGS under section 425 of the Companies Act. The Scheme is set out in full in Part VII of this document. Under the terms of the Scheme, CAT will issue New CAT Shares to OGS Shareholders and their existing OGS Shares will be cancelled. In consideration for the cancellation of their OGS Shares, OGS Shareholders will receive: for each OGS Share 0.3620 New CAT Shares OGS ADS holders will receive New CAT ADSs on the following basis: for each OGS ADS 0.3620 New CAT ADSs Upon completion of the Merger which is expected to occur by 31 March 2003, OGS Shares will be issued to CAT whereupon OGS will become a wholly-owned subsidiary of CAT. CAT Shares will continue to be listed on the London Stock Exchange. Its ADSs will also continue to trade on NASDAQ. Upon completion of the Merger, and based on the current issued share capital of each company, CAT Shareholders will hold approximately 64.3 per cent, and OGS Shareholders will hold approximately 35.7 per cent, of the issued share capital of CAT. The terms of the Merger value each OGS Share at 195.5 pence and the entire issued share capital of OGS at approximately (pound)109.6 million, based on a Closing Price of 540.0 pence per CAT Share on 22 January 2003. The name of CAT will be changed in due course as part of the management's commitment to building a leading biopharmaceutical company. In cases where fractional entitlements to New CAT Shares arise from the Merger, these will not be issued to OGS Shareholders but will be dealt with as provided in paragraph 11 below. The Scheme will require approval by OGS Shareholders at the OGS Court Meeting and the OGSEGM, the CAT Shareholders at the CAT EGM and the sanction of the Court at the Court Hearing. The OGS Court Meeting and the OGS EGM and the nature of the approvals required to be given at them are described in more detail in paragraph 4 below. All OGS Shareholders are entitled to attend the Court Hearing in person or to be represented by Counsel to support or oppose the sanctioning of the Scheme. The Merger is subject to a number of conditions (set out in Part IV of this document), including approval of the Merger and related matters by the shareholders of both OGS and CAT and the obtaining of relevant regulatory consents. The Merger can only become effective if all conditions to the Merger, including shareholder approvals, the obtaining of relevant regulatory consents and the sanction of the Court in respect of the Scheme, have been satisfied or waived. The Scheme will become effective upon the delivery to the Registrar of Companies by OGS of a copy of the Order and registration of the Order which, subject to the sanction of the Scheme by the Court, is expected to occur by 31 March 2003. Unless the Scheme becomes effective by no later than 30 April 2003, or such later date, if any, as OGS and CAT may agree and the Court may allow, the Merger will not proceed. 3. Financial effects of the Merger The terms of the Merger, under which OGS Shareholders will receive 0.3620 New CAT Shares for every OGS Share held, are based on the current issued share capital of each company. On the bases and assumptions set out in the notes below, and assuming that the Scheme becomes effective and the Merger is completed, the following table shows, for illustrative purposes only, the financial effect of receiving New CAT Shares on the capital value for a holder of 100 OGS Shares. Capital value Note Market value of 36.2 New CAT Shares (1) (pound)167.97 Market value of 100 OGS Shares (2) (pound)152.50 Increase in capital value per 100 OGS Shares (3) (pound)15.47 Notes: (1) The market value of New CAT Shares is based on the Closing Price of 464.0 pence per CAT Share on 4 February 2003 being the last practicable date prior to the publication of this document. (2) The market value of OGS Shares is based on the Closing Price of 152.5 pence per OGS Share on 22 January 2003 being the last Business Day prior to the announcement of the Merger. (3) In assessing the financial effects of receiving New CAT Shares, no account has been taken of any potential taxation liability. 4. Consents and meetings The Scheme is subject to the approval of OGS Shareholders at the OGS Court Meeting and its implementation will also require the approval of OGS Shareholders at the separate OGS EGM, both of which will be held at the offices of Financial Dynamics, Holborn Gate, 26 Southampton Buildings, London, WC2A 1PB on 11 March 2003. The OGS Court Meeting will start at 10.00 a.m. and the OGS EGM at 10.15 a.m. (or as soon thereafter as the OGS Court Meeting is concluded or adjourned) on that date. The OGS Court Meeting is being held at the direction of the Court to seek the approval of OGS Shareholders to the Scheme. The OGS EGM is being convened to enable the OGS Directors to implement the Scheme and to amend the OGS Articles, as described below. Notices of both the OGS Court Meeting and the OGS EGM are set out at the end of this document. Entitlement to attend and vote at each meeting and the number of votes which may be cast at each meeting will be determined by reference to the register of members of OGS at the Voting Record Time. OGS Court Meeting The OGS Court Meeting has been convened for 10.00 a.m. on 11 March 2003 to enable OGS Shareholders to consider and, if thought fit, approve the Scheme. At the OGS Court Meeting, voting will be by poll and not a show of hands and each holder of OGS Shares who is present in person or by proxy will be entitled to one vote for each OGS Share held. The approval required at the OGS Court Meeting is that those voting to approve the Scheme should: (i) represent a simple majority in number of those OGS Shareholders present and voting in person or by proxy; and (ii) also represent three-fourths in value of the OGS Shares held by those OGS Shareholders present and voting in person or by proxy. It is important that as many votes as possible are cast at the OGS Court Meeting so that the appropriate resolution can be passed and that the Court may be satisfied that there is a fair representation of OGS Shareholder opinion. If you are the registered holder of any OGS Shares, you are strongly urged to complete and return your Form of Proxy for the OGS Court Meeting as soon as possible. OGS EGM In addition, the OGS EGM has been convened for the same date at 10.15 a.m. (or as soon thereafter as the OGS Court Meeting is concluded or adjourned) to consider and, if thought fit, pass a special resolution (which requires a vote in favour of not less than 75 per cent. of the votes cast): (i) to approve the Scheme and to authorise the OGS Directors to take such action as they consider necessary or appropriate to carry the Scheme into effect; (ii) to approve the cancellation of OGS Shares and the subsequent issue of new OGS Shares of 5 pence each in OGS to CAT (and/or its nominee(s)) in accordance with the Scheme (on the basis set out in the first paragraph of paragraph 2 "Summary of the terms of the Merger" above); and (iii) to amend the OGS Articles in the manner described below. Amendments to the OGS Articles The special resolution to be proposed at the OGS EGM includes proposals to amend the OGS Articles to ensure that: (a) any OGS Shares issued under the OGS Share Option Schemes or otherwise between the Voting Record Time and 6.00 p.m. on the last Business Day before the Hearing Date will be subject to the Scheme (as explained in more detail in paragraph 5 below); (b) no OGS Shares will be issued between 6.00 p.m. on the last Business Day before the Hearing Date and the time the Scheme becomes effective; and (c) any shares in OGS issued to any person (other than to CAT and/or its nominee(s)) after the Effective Date will be automatically exchanged for New CAT Shares on the same terms as under the Scheme. These amendments are designed to avoid any person (other than members of the CAT Group) being left with OGS Shares once the Scheme has become effective and after dealings in OGS Shares have ceased on the London Stock Exchange (which will occur at the close of business on the Business Day before the Effective Date). Part (3) of the special resolution set out in the notice of the OGS EGM at Part IX of this document seeks the approval of OGS Shareholders for such amendments. Each holder of OGS Shares will be entitled to attend and vote at the OGS EGM. If you are the registered holder of any OGS Shares, you are strongly urged to complete and return your Form of Proxy for the OGS EGM as soon as possible. CAT EGM The Merger is also conditional upon the passing by CAT Shareholders of an ordinary resolution to be proposed at the CAT EGM to approve the Merger (as required by the Listing Rules), an increase in the share capital of CAT and the issue of the New Cat Shares. OGS Court Hearing The OGS Court Hearing is currently scheduled for 27 March 2003. All OGS Shareholders are entitled to attend the Court Hearing in person or to be represented by Counsel to support or oppose the sanctioning of the Scheme. The Merger will become effective on the delivery by OGS to the Registrar of Companies of a copy of the Order sanctioning the Scheme and confirming the reduction of capital involved therein. Subject to the requisite approvals to the Merger being obtained from OGS Shareholders and CAT Shareholders, the conditions to which the Merger and Scheme are subject to being fulfilled or, if applicable, waived and the sanction of the Court, implementation of the Merger is expected to occur by 31 March 2003. Unless the Scheme becomes effective by no later than 30 April 2003, or such later date, if any, as OGS and CAT may agree and the Court may allow, the Merger will not proceed. 5. Structure of the Scheme It is proposed that, under the Scheme, all the OGS Shares in issue prior to the Voting Record Time will be cancelled. Any further OGS Shares issued before 6.00 p.m. on the day before the Hearing Date and in respect of which the holders are or have consented to be bound by the Scheme will also be cancelled. New ordinary shares of 5 pence each in OGS will be issued by OGS to CAT by capitalisation of the reserve arising from the cancellation of the OGS Shares so that OGS becomes a wholly-owned subsidiary of CAT. OGS Shareholders who are on the register of OGS at the Scheme Record Time (that is, 6.00 p.m. on the last Business Day prior to the Effective Date) will receive New CAT Shares, fully paid, on the basis set out in paragraph 2 above. Shares in OGS issued at or after 6.00 p.m. on the day before the Hearing Date will not be subject to the Scheme. Accordingly, it is proposed that the OGS Articles be amended so that ordinary shares of 5 pence each in OGS issued on or after the Effective Date (other than to a member of CAT Group) will be automatically exchanged for New CAT Shares on the same terms as under the Scheme. It is expected that the Scheme will become effective and that the Merger will complete by 31 March 2003. The Scheme can only become effective if all the conditions to which the Scheme is subject, including shareholder approvals, the obtaining of relevant regulatory consents and the sanction of the Court, have been satisfied or waived by no later than 30 April 2003 or such later date, if any, as OGS and CAT may agree and the Court may allow. The Scheme will become effective upon a copy of the Order being registered by the Registrar of Companies. Once the Scheme becomes effective, the terms will be binding on all OGS Shareholders, irrespective of whether or not they attended the OGS Court Meeting and irrespective of the manner in which they voted. 6. Effect of the Merger on the OGS Share Option Schemes As a result of the Merger, options granted under the OGS Share Option Schemes will become exercisable (if not already exercisable) after the Scheme is sanctioned by the Court. If not exercised, the options will eventually lapse. Any shares in OGS issued after the Effective Date upon exercise of options will automatically be exchanged for new shares in CAT on same terms as under the Scheme subject to the proposed changes to the OGS Articles to be proposed at the OGS EGM. As an alternative, CAT will also offer OGS option holders equivalent options over shares in CAT in exchange for the release of their existing options ("Rollover Options"). The aggregate value of shares under option (determined by reference to the exchange ratio applicable to the Merger) and the total exercise price will be the same for the original options and the Rollover Options. Any vesting or performance conditions attaching to the original options would be replicated in the Rollover Options (with appropriate credit given for vesting or performance prior to the date of the Merger), save for Rollover Options granted under the approved part of the Executive Scheme, where the rules of that scheme specify that the performance conditions will be treated as met. The Rollover Options will not become exercisable or lapse as a consequence of the Merger. For option holders resident in the US, the offer of Rollover Options will only be made to "accredited investors" (as such term is defined in Rule 501 under the Securities Act) in a transaction that is exempt from the registration requirements of the Securities Act. Shares in CAT issuable upon exercise of such Rollover Options may not be sold without registration under the Securities Act, except pursuant to the applicable resale provisions of Rule 144 under the Securities Act, or another applicable exemption from the registration requirements of the Securities Act or in a transaction not subject to such requirements (including a transaction that satisfies the applicable requirements for resales outside the United States pursuant to Regulation S under the Securities Act). OGS option holders in the US should consult their own legal advisors with respect to the legal consequences of the Scheme in their particular circumstances. Rollover Options granted in respect of OGS options granted under the 1994 Scheme will provide that redundant leavers are allowed one year from leaving in which to exercise their options (rather than six months as specified in that scheme). Additionally, for other leavers under that scheme, exercise of options will be permitted at the discretion of the directors for a period not exceeding one year after leaving (rather than the options lapsing automatically, as specified in the scheme) and CAT has confirmed that it will exercise its discretion in favour of G. Kirk Raab and Professor Raymond Dwek after they leave the Group, if the options have not previously been exercised. These measures broadly conform the leaver provisions with those applicable to options granted under the Executive Scheme. 7. The OGS Directors and the effect of the Scheme on their interests The interests of the OGS Directors in the share capital of OGS and in the OGS Share Option Schemes are set out in paragraph 4 of Part VI of this document. OGS Directors who hold share awards or options under the OGS Share Option Schemes will be treated in the manner set out in paragraph 6 of this Part III. The OGS Directors are affiliates, as such term is defined in Rule 144 under the Securities Act, of OGS for the purposes of the Securities Act and are subject to certain transfer restrictions relating to the New CAT Shares which they receive under the Scheme under the US securities laws more particulary described in paragraph 2 of Part V of this document. Details of the service contracts (including termination provisions and payments) of the OGS Directors and the effect of the Merger on these contracts are set out in paragraph 6 of Part VI of this document. Save as disclosed in paragraph 6 of Part VI of this document, the total emoluments receivable by OGS Directors will not be varied automatically as a consequence of the Merger except that the emoluments of OGS Directors who are Proposed Directors will be reviewed by the remuneration committee of CAT and may be varied following completion of the Merger. It is proposed that, upon the Scheme becoming effective, the Board of CAT will be as set out in paragraph 2(c) of Part VI of this document. Save as described above and in paragraph 6 of Part VI of this document, the effect of the Scheme on the interests of the OGS Directors does not differ from its effect on the like interests of other persons. 8. Inducement fee CAT and OGS have entered into an inducement fee agreement under which each party has agreed to pay the other an amount of approximately (pound)1.1 million by way of compensation if the Merger lapses: (i) following a failure by its shareholders to pass any resolution required to implement the Merger; or (ii) if the relevant party's Board fails to recommend or withdraws or modifies its recommendation of the Merger or fails to take any steps which are necessary to implement the Merger. CAT and OGS have also entered into the Merger Agreement which provides that both parties will use their reasonable endeavours to achieve the satisfaction of the conditions set out in paragraph 1 of Part IV of this document and to meet the timetable for implementation of the Scheme which has been agreed to between the parties. Further details on the inducement fee agreement and the Merger Agreement are set out in paragraph 9 of Part VI of this document. 9. UK taxation The comments set out below summarise the UK taxation treatment of holders of OGS Shares under the Scheme and of holders of New CAT Shares. They are based on current UK law and published Inland Revenue practice currently in force. They are intended as a general guide and apply only to shareholders resident or (if individuals) ordinarily resident for tax purposes in the UK who hold OGS Shares and New CAT Shares as investments (otherwise than under any scheme which benefits from special tax exemptions, such as personal equity plans or individual savings accounts) and not as trading stock and who are the beneficial owners of those shares. Shareholders who are in any doubt about their taxation position, or who are resident in a jurisdiction outside the UK, should consult their own professional advisers. UK Taxation of Capital Gains ("CGT") Subject to the following paragraphs, roll-over relief should be available to OGS Shareholders in respect of the cancellation of their existing OGS Shares and the issue to them of New CAT Shares. Accordingly, such OGS Shareholders should not be treated as having made a disposal of their OGS Shares for CGT purposes, and the New CAT Shares issued should be treated as the same asset and as having been acquired at the same time as the OGS Shares. The New CAT Shares should, therefore, have the same base cost as the OGS Shares which they replace. To the extent that OGS Shareholders receive cash in respect of fractional entitlements to New CAT Shares and do not receive New CAT Shares, this will generally be treated as a disposal of OGS Shares for CGT purposes which may, depending on the shareholders' individual circumstances, give rise to a liability to CGT. OGS Shareholders who receive cash and also receive New CAT Shares should not generally be treated as making a disposal or part disposal of OGS Shares in respect of the receipt of cash. Instead, the cash received should be deducted from the base cost otherwise attributable to the CAT Shares for CGT purposes. OGS Shareholders who, alone or together with persons connected with them, hold more than 5 per cent. of any class of the OGS Shares will be eligible for the above treatment only if the Scheme is effected for bona fide commercial reasons and does not form part of a scheme or arrangement of which the main purpose, or one of the main purposes, is an avoidance of liability to CGT or corporation tax. OGS Shareholders are advised that clearance has been applied for in respect of the Scheme under Section 138 of the Taxation of Chargeable Gains Act 1992. On the basis that such clearance is obtained, any such OGS Shareholder should be treated in the manner described above. OGS and CAT have also applied for confirmation from the Inland Revenue under Section 707 of the Income and Corporation Taxes Act 1988 that Section 703 of the Act, which allows for the cancellation of tax advantages arising from certain transactions and securities and which would affect the statements made above if it were to apply to the Scheme, will not be applicable to the Scheme. A disposal of New CAT Shares by a shareholder resident or ordinarily resident for tax purposes in the UK or a shareholder who carries on a trade, profession or vocation in the UK through a branch or agency and who has used, held or acquired the New CAT Shares for the purposes of such trade, profession or vocation or such branch or agency may, depending on the shareholder's circumstances, and subject to any available exemption or relief, give rise to a chargeable gain or an allowable loss for CGT purposes. A shareholder who is an individual and who has, on or after 17 March 1998, ceased to be resident or ordinarily resident for tax purposes in the UK for a period of less than 5 tax years and who disposes of New CAT Shares during that period may also be liable, on his return, to CGT (subject to any available exemption or relief). Dividends Under current UK taxation legislation, no tax will be deducted from dividends paid by CAT. A New CAT Shareholder who is an individual resident (for tax purposes) in the UK and who receives a dividend paid by CAT will be entitled to a tax credit equal to 1/9th of the dividend. The individual will be taxable on the total of the dividend and the related tax credit (the "gross dividend"), which will be regarded as the top slice of the individual's income. The tax credit will, however, be treated as discharging the individual's liability to income tax in respect of the gross dividend, unless and except to the extent that the gross dividend falls above their threshold for the higher rate of income tax, in which case the individual will, to that extent, pay tax on the gross dividend of an amount determined by applying the Schedule F upper rate (currently 32.5 per cent.) to the dividend and the tax credit, and then deducting the tax credit. So, for example, a dividend of (pound)80 will carry a tax credit of (pound)8.89 (l/9th of (pound)80) and to the extent that the dividend and the related tax credit fall above the threshold for the higher rate of income tax, a taxpayer would be subject to income tax on (pound)88.89 ((pound)80 + (pound)8.89) at the 32.5 per cent. rate i.e. (pound)28.89 less a tax credit of (pound)8.89 leaving a tax charge of (pound)20. With limited exceptions, New CAT Shareholders whose liability to income tax for the relevant year of assessment is less than the amount of the tax credits in respect of dividends paid by CAT will not be entitled to claim payment of the tax credit. A New CAT Shareholder that is a company resident (for tax purposes) in the UK will not normally be liable to corporation tax on any dividend it receives from CAT. UK Stamp Duty and SDRT No UK stamp duty or SDRT should be payable by OGS Shareholders in relation to the allotment and issue to them of New CAT Shares pursuant to the Scheme. Special rules may apply to shares held in or issued into depositary receipt or clearance service arrangements, although no stamp duty or SDRT should generally be payable by holders of OGS ADSs on the cancellation of those ADSs and the issue of New CAT ADSs under the Scheme. A transfer for value of New CAT Shares will generally be subject to UK stamp duty or to SDRT. Stamp duty and SDRT are normally a liability of the purchaser. Stamp duty is generally payable on an instrument transferring New CAT Shares at 0.5 per cent. of the amount or value of the consideration for the transfer of the New CAT Shares (rounded up to the nearest multiple of (pound)5). A charge to SDRT will also normally arise on an unconditional agreement to transfer New CAT Shares (equal to 0.5 per cent. of the amount or value of the consideration payable for the transfer). However, if within six years of the date on which the agreement is made (or, if that agreement is conditional, the date on which the condition is satisfied) an instrument of transfer is executed pursuant to the agreement and is duly stamped, any SDRT paid will be refunded (generally, but not necessarily, with interest) provided that a claim for repayment is made within the six year period, and any outstanding liability to SDRT will be cancelled. Paperless transfers of New CAT Shares within CREST are generally liable to SDRT, rather than stamp duty, at the rate of 0.5 per cent. of the amount or value of the consideration payable. CREST is obliged to collect SDRT on relevant transactions settled within CREST. Deposits of New CAT Shares in CREST will not be subject to stamp duty and, unless the transfer into CREST is itself for consideration, will not be subject to SDRT. The above statements are intended as a general guide to the current position. 10. Certain US Federal income tax consequences of the Merger For further details on this please refer to paragraph 13(b) of Part X of the Listing Particulars. 11. Settlement, listing and dealings Application has been made to the UK Listing Authority for the New CAT Shares to be admitted to the Official List and to the London Stock Exchange, for the New CAT Shares to be admitted to trading on the London Stock Exchange's market for listed securities. It is expected that Admission will become effective and dealings, for normal settlement, will commence on the Effective Date. CAT will seek to have the New CAT ADSs quoted on NASDAQ commencing on the Effective Date. The London Stock Exchange and the UK Listing Authority will also be requested to cancel the trading in OGS Shares on the London Stock Exchange's market for listed securities and the listing of the OGS Shares on the Official List with effect from close of business on the dealing day immediately prior to the Effective Date. The last day of dealings in OGS Shares on the London Stock Exchange will, therefore, be the last dealing day before the Effective Date. No transfers of OGS Shares (other than transfers to any member or members of the CAT Group) will be registered after the Scheme Record Time. On the Effective Date share certificates in respect of OGS Shares will cease to be valid and should, if so requested by OGS or its agents, be sent to OGS for cancellation. An application to cancel the quotation of OGS ADSs on NASDAQ and a filing with the SEC to de-register OGS' ADSs will be made shortly after the Effective Date. Subject to the Merger becoming effective (and except as provided in Part V of this document in relation to overseas OGS Shareholders), settlement of the consideration to which any OGS Shareholder is entitled under the Merger will be effected in the following manner: (a) OGS Shares in uncertificated form ("CREST") Where, at the Scheme Record Time, an OGS Shareholder holds OGS Shares in uncertificated form, the New CAT Shares to which such OGS Shareholder is entitled will be issued to such person in uncertificated form through CREST. CAT will procure that CRESTCo is instructed to credit the appropriate stock account in CREST of such OGS Shareholder with such person's entitlement to New CAT Shares at the commencement of dealings in the New CAT Shares. CAT reserves the right to issue New CAT Shares in certificated form in the manner referred to in paragraph 11(b) below, if for any reason outside its reasonable control, it is not able to effect settlement in uncertificated form in accordance with this paragraph 11(a). (b) OGS Shares in certificated form Where, at the Scheme Record Time, an OGS Shareholder holds OGS Shares in certificated form, the New CAT Shares to which such OGS Shareholder is entitled will be issued in certificated form. Definitive certificates for New CAT Shares will be despatched by first-class post to the address appearing in the register of members of OGS as at the Scheme Record Time immediately prior to despatch or, in the case of joint holders, to the holder whose name stands first in such register in respect of the joint holders or in accordance with any special instructions regarding communications. Definitive certificates will be despatched within 14 days following the Effective Date. Temporary documents of title will not be issued pending the despatch by post of new definitive share certificates. Holders wishing to register transfers of the New CAT Shares prior to the issue of the new share certificates will be required to produce their existing certificates for OGS Shares to the CAT Registrar. On the issue of definitive share certificates for the New CAT Shares, the certificates for the existing OGS Shares will cease to be of value. Every holder of OGS Shares who has not already produced his or her existing certificate(s) to the CAT Registrar will be bound on the request of OGS to deliver up to OGS, or to any person appointed by OGS, the existing certificate(s) for cancellation. (c) OGS ADSs Upon the Effective Date: (i) the OGS Shares underlying each OGS ADS will be cancelled and New CAT Shares will be issued to the OGS ADS Depositary based on the exchange ratio of 0.3620 New CAT Shares for each OGS Share; (ii) the Deposit Agreement will be amended to be identical to the CAT Deposit Agreement and the OGS ADSs facility will become part of the CAT ADS facility; and (iii) each holder of OGSADSs will be required to exchange his or her ADSs for CAT ADSs based on the exchange ratio of 0.3620 New CATADSs for each OGS ADS. Following the Effective Date, The Bank of New York, as depositary for the OGS ADSs and CAT ADSs facilities, will mail a notice to registered holders of OGS ADSs regarding the mechanics of the exchange of their existing OGS ADSs for New CATADSs. Registered holders will need to follow the instructions set out in the notice. If you hold your OGS ADSs through a broker, financial institution or other nominee or otherwise, you must rely on the procedures of your broker, financial institution, or other nominee. (d) General All documents and remittances sent to OGS Shareholders (or in accordance with their directions) will be despatched at their own risk. All mandates, instructions and other instruments in force relating to holdings in OGS Shares will, unless and until amended or revoked, continue in force and be deemed as from the Effective Date to relate to payments and notices to or by CAT in respect of New CAT Shares. (e) Fractional entitlements Fractional entitlements to a New CAT Share will not be issued to OGS Shareholders, but will be aggregated and sold in the market and, in the case of OGS Shares held in certificated form, the relevant share of the proceeds will be paid by cheque to the relevant OGS Shareholder and will be despatched in the manner specified in paragraph 11(b) above, no later than 14 days after the Effective Date. In the case of OGS Shares held in uncertificated form, CAT will ensure that an assured payment obligation in respect of the sums payable in respect of fractional entitlements is created in accordance with the CREST assured payment arrangements no later than 14 days after the Effective Date provided that CAT may (if, for any reason, it wishes to do so) make payment of the said sums by cheque as aforesaid. Fractional entitlements to a New CAT ADS will not be issued to any holder of an OGS ADS. All fractions to which holders of OGS ADSs would otherwise have been entitled will be aggregated and sold in the market after the Effective Date and the ADS Depositary will receive an amount in pounds sterling equal to the total amount payable in respect of fractional entitlements in respect of OGS Shares held by the ADS Depositary. Such amount will be converted into US dollars by the ADS Depositary pursuant to the terms and conditions of the Deposit Agreement. It is expected that once the ADS Depositary has received the funds, holders of OGS ADSs will receive their pro rata portion (if any) of the US dollars from the ADS Depositary upon surrender of their OGS ADSs in accordance with the terms of the Deposit Agreement. 12. Overseas shareholders Overseas holders of OGS Shares should refer to Part V of this document, which contains important information relevant to such holders. 13. Action to be taken OGS Shareholders will find the following documents enclosed with this document: (a) the BLUE Form of Proxy which is to be used for the OGS Court Meeting; and (b) the GREEN Form of Proxy which is to be used for the OGS EGM; or (c) (if you are a holder of OGS ADSs) a voting instruction card. It is important that as many votes as possible are cast at the OGS Court Meeting so that the appropriate resolution can be passed and so that the Court may be satisfied that there is a fair representation of OGS Shareholder opinion. OGS Shareholders are therefore urged to sign and return the completed Forms of Proxy as soon as possible. Therefore, whether or not you propose to attend the meetings in person, you are requested, if you hold OGS Shares, to complete and return both Forms of Proxy. Completed Forms of Proxy should be returned to OGS' Registrars, Lloyds TSB Registrars, at The Causeway, Worthing, West Sussex, BN99 6US as soon as possible and in any case so as to be received by them no later than 10.00 a.m. on 9 March 2003 for the OGS Court Meeting and 10.15 a.m. on 9 March 2003 for the OGS EGM. The return of the Forms of Proxy will not prevent you from attending either of the meetings and voting in person if you wish. The Form of Proxy in respect of the OGS Court Meeting may also be handed to the Chairman of the OGS Court Meeting before the start of the meeting and will still be valid. However, in the case of the OGS EGM, the Form of Proxy will be invalid unless it is lodged so as to be received no later than 10.15 a.m. on 9 March 2003. The Forms of Proxy can be revoked or amended at any time up to 10.15 a.m. on 9 March 2003 (in the case of the Form of Proxy for the OGS EGM) or prior to the start of the meeting (in the case of the Form of Proxy for the OGS Court Meeting). If you wish to amend or revoke your Form(s) of Proxy after you have returned them to OGS' Registrars, you should contact the Registrars at the address given above. Forms of Proxy returned by fax for either the OGS Court Meeting or the OGS EGM will NOT be valid. If you are an OGS ADS holder, you may only vote in person at the OGS Court Meeting and/or the OGS EGM if you become a registered holder of OGS Shares by arranging for the surrender of your OGS ADSs in accordance with the terms and conditions of the Deposit Agreement. Please contact The Bank of New York, the ADS Depositary, on the US telephone number +1 (212) 815 2783 for further information on surrendering your OGS ADSs. Alternatively, you may instruct The Bank of New York, the ADS Depositary, how to vote the OGS Shares underlying your OGS ADSs at the OGS Court Meeting and/or OGS EGM. A voting instruction card is enclosed for this purpose and must be completed, signed and returned to the ADS Depositary so that it receives the voting instruction card no later than 5.00 p.m. (New York time) on 4 March 2003. In respect of the OGS EGM only, if the voting instruction card is signed and returned but no instructions are indicated in the appropriate box, or if the voting instruction card is not signed and returned, or if the voting instruction card is not returned, a discretionary proxy will be given to the chairman of the OGS EGM to vote the relevant OGS ADSs. If you hold your OGS ADSs indirectly, you must rely on the procedures of your bank, broker or financial institution through which you hold your OGS ADSs. If you would like any further help completing the Forms of Proxy please contact OGS' Registrars, Lloyds TSB Registrars, on +44 (0)870 600 3953 or +44 (0)121 415 7047 between 9.00 a.m. and 5.00 p.m. Monday to Friday (from the date of this document until 10 March 2003). For legal reasons, the Registrars will not be able to provide advice on the merits of the Merger itself or give financial advice. 14. Further information The terms of the Scheme are set out in full in Part VII of this document. Further information regarding OGS and CAT is set out in the Listing Particulars. Details of documents available for inspection are given in paragraph 12 of Part VI of this document and paragraph 18 of Part X of the Listing Particulars. Yours faithfully, Michael Hill Managing Director Goldman Sachs International PART IV CONDITIONS TO IMPLEMENTATION OF THE SCHEME AND THE MERGER The Merger is conditional upon the Scheme becoming unconditional and becoming effective by not later than 30 April 2003 or such later date (if any) as OGS and CAT may agree and the Court may allow. 1. Conditions of the Scheme The Scheme is conditional upon: (a) the approval by a majority in number representing three-fourths in value of the holders of OGS Shares present and voting, either in person or by proxy, at the OGS Court Meeting; (b) any resolution or resolutions required to approve and implement the Scheme being passed at the OGS EGM; (c) any resolution or resolutions of CAT Shareholders required in connection with the approval of the Merger and implementation of the Scheme being passed at the CAT EGM; (d) the admission to the Official List of the New CAT Shares becoming effective in accordance with the Listing Rules and the admission of such shares to the London Stock Exchange's market for listed securities becoming effective or (if CAT and OGS so determine and subject to the consent of the Panel) the UK Listing Authority agreeing or confirming its decision to admit such shares to the Official List and the London Stock Exchange agreeing to admit such shares to trading subject only to (i) the allotment of such shares and/or (ii) the Scheme becoming unconditional in all respects (other than in respect of this paragraph 1(d)); and (e) the sanction (with or without modification) of the Scheme and confirmation of the reduction of capital involved by the Court, an office copy of the Order being delivered for registration to the Registrar of Companies in England and Wales and registration of the Order confirming the reduction of capital involved in the Scheme with the Registrar of Companies in England and Wales. 2. Conditions of the Merger CAT and OGS have agreed that, subject as stated in paragraph 3 below, the Merger is also conditional upon, and, accordingly, the necessary action to make the Scheme effective will not be taken unless the following conditions are satisfied or waived as referred to below prior to the Scheme being sanctioned by the Court: (a) the Office of Fair Trading indicating in terms reasonably satisfactory to CAT and OGS that it is not the intention of the Secretary of State for Trade and Industry to refer the Merger or any matters arising therefrom to the Competition Commission;

(e) CAT not having discovered regarding OGS, and OGS not having discovered regarding CAT that: (i) any adverse financial, business or other information in relation to circumstances existing prior to 23 January 2003 and which is material in the context of the relevant group has not been publicly disclosed by the relevant group or otherwise fairly disclosed prior to such date (in the case of such information regarding CAT) by CAT to OGS and (in the case of such information regarding OGS) by OGS to CAT;

or (ii) that save as fairly disclosed to CAT by OGS regarding the OGS Group or to OGS by CAT regarding the CAT Group prior to 23 January 2003, there is, or is reasonably likely to be, any liability (whether actual or contingent) to make good, repair, reinstate or clean up any property now or previously owned, occupied or made use of by any past or present member of the relevant group or any other property or any controlled waters under any environmental legislation, regulation, notice, circular, order or other lawful requirement of any relevant authority or otherwise which would be material in the context of the relevant group; or (iii) that, save as fairly disclosed to CAT by OGS regarding the OGS Group or to OGS by CAT regarding the CAT Group prior to 23 January 2003, circumstances exist whereby a person or class of persons is proposing to bring a claim in respect of any product or process of manufacture or materials used therein now or previously manufactured, sold or carried out by any past or present member of the relevant group which would be material and adverse in the context of the relevant group. For the purpose of these conditions: (a) "authorisations" means authorisations, orders, grants, recognitions, determinations, certificates, confirmations, consents, licences, clearances, permissions, advices and approvals; and (b) "relevant authority" means any central bank, government, government department or governmental, quasi governmental, supranational, statutory, regulatory or investigative body, court, stock exchange, trade agency, association, institution or professional or environmental body or any other similar person or body whatsoever in any relevant jurisdiction. 3. Subject to paragraph 4 below, CAT and OGS, acting together, may waive all or any of the conditions contained in paragraphs 2(a), (b), (c) and (d). CAT reserves the right (but shall be under no obligation) to waive all or any of the conditions contained in paragraph 2(g) above, and in paragraphs 2(e), (h) and (i) above (in so far as they relate to OGS), in whole or in part, and OGS reserves the right (but shall be under no obligation) to waive all or any of the conditions in paragraph 2(f) above, and in paragraphs 2(e), (h) and (i) above (in so far as the relate to CAT), in whole or in part, for the purposes of the Merger and the Scheme. 4. OGS shall only be entitled to invoke a condition in circumstances where it would be able to invoke the condition if it were an offeror for CAT in an offer governed by the City Code. 5. Save with the consent of the Panel, the Merger will lapse and the Scheme will not proceed if, before the date of the OGS Court Meeting, there is a reference to the Competition Commission. PART V OVERSEAS SHAREHOLDERS 1. General As regards persons resident in, or citizens of, jurisdictions outside the United Kingdom ("overseas shareholders"), the implementation of the Merger may be affected by the laws of those relevant jurisdictions. Such overseas shareholders should inform themselves about and observe any applicable legal requirements. It is the responsibility of overseas shareholders to satisfy themselves as to the full observance of the laws of the relevant jurisdiction in connection with such applicable legal requirements, including the obtaining of any governmental, exchange control or other consents which may be required, or the compliance with other necessary formalities that are required to be observed and the payment of any issue, transfer or other taxes due in such jurisdiction. In any case where the issue of New CAT Shares would infringe the laws of any jurisdiction outside the United Kingdom or necessitate compliance with any special requirement, the Scheme provides that such New CAT Shares may, at the discretion of CAT, either be issued to a nominee and then sold or issued to the relevant holder of OGS Shares and sold on his or her behalf, in each case with the net proceeds of sale being remitted to the overseas shareholder. This document has been prepared for the purposes of complying with English law, the City Code and the Listing Rules and the information disclosed may be different from that which would have been disclosed if this document had been prepared in accordance with the laws of the jurisdictions outside the United Kingdom. THIS DOCUMENT DOES NOT CONSTITUTE AN OFFER TO SELL OR THE SOLICITATION OF AN OFFER TO BUY ANY SECURITY, NOR SHALL THERE BE ANY SALE, ISSUANCE OR TRANSFER OF THE SECURITIES REFERRED TO IN THIS DOCUMENT IN ANY JURISDICTION IN CONTRAVENTION OF APPLICABLE LAW. Overseas shareholders should consult their own legal and tax advisers with respect to the legal and tax consequences of the Scheme in their particular circumstances. 2. US securities laws The New CAT Shares to be issued to OGS Shareholders under the Scheme will be issued in reliance upon the exemptions from the registration requirements of the Securities Act and the requirements of any US state securities laws provided by sections 3(a)(10) and 18(b) of the Securities Act, respectively, and, as a consequence, will not be registered under the Securities Act or any US state securities laws. Except for the circumstances described in the next paragraph, the New CAT Shares issuable to OGS Shareholders pursuant to the Scheme should not be treated as "restricted securities" within the meaning of Rule 144(a)(3) under the Securities Act and may be resold by former OGS Shareholders without restriction under the Securities Act. Under US securities laws, an OGS Shareholder who is deemed to be an "affiliate" (as such term is defined in Rule 144 under the Securities Act) of CAT or of OGS before the Effective Date, or of CAT following the Effective Date may not resell New CAT Shares received pursuant to the Scheme without registration under the Securities Act, except pursuant to the applicable resale provisions of Rule 145(d) under the Securities Act or another applicable exemption from the registration requirements of the Securities Act or in a transaction not subject to such requirements (including a transaction that satisfies the applicable requirements for resales outside the United States pursuant to Regulation S under the Securities Act). Whether a person is an affiliate of a company for such purposes depends upon the circumstances, but affiliates of a company can include certain officers and directors and significant shareholders. OGS Shareholders who believe they may be affiliates of CAT or OGS should consult their own legal advisers prior to any sales of New CAT Shares received pursuant to the Scheme. For the purpose of qualifying for the exemption from the registration requirements of the Securities Act provided by section 3(a)(10) thereof with respect to New CAT Shares, OGS will advise the Court at the Court Hearing that its sanctioning of the Scheme will be relied upon by CAT for such purpose as an approval of the Scheme following a hearing on its fairness to OGS Shareholders, at which hearing all such holders are entitled to attend in person or through counsel to support or oppose the sanctioning of the Scheme and with respect to which notification has been given to all such holders. 3. Other overseas securities laws No steps have been taken, nor will any be taken, to enable the New CAT Shares to be offered in compliance with the applicable securities laws of Canada or Japan and no prospectus in relation to the New CAT Shares has been, or will be, lodged with or registered by the Australian Securities and Investments Commission. Accordingly, no New CAT Shares may be offered, sold, transferred, resold, delivered or distributed, directly or indirectly, in or into or from Canada, Japan or Australia (except in transactions exempt from or not subject to the registration requirements of the relevant securities laws of Canada, Japan or Australia). 4. US Filings Each of CAT and OGS is subject to the information requirements of the US Exchange Act of 1934, as amended, applicable to foreign private issuers having securities registered under section 12 thereof, and in accordance therewith file annual reports and other information with the SEC.

OGS Directors' service contracts and emoluments Set out below are details of the service contracts for the OGS Directors and those OGS Directors who are also Proposed Directors. Certain OGS Directors have agreed variations to their service contracts or letters of appointment (as described below) which will become effective upon completion of the Merger. (a) OGS Directors Executive Directors' service contracts As at 4 February 2003 (being the last practicable date prior to publication of this document), no new directors' service contracts had been entered into and, save as described in paragraphs 6(a)(v) and 6(b) below, there have been no amendments to the terms of existing service contracts within the preceding six months. OGS has service contracts with the Chairman and the executive directors. With respect to the executive directors of OGS, their employment contracts generally provide that: (i) upon termination, they shall not disclose any confidential information relating to OGS or OGS' partners; (ii) upon termination, they may not compete with OGS for a period of at least six months in the product and service areas with respect to which OGS operates; (iii) upon termination, they may not solicit OGS' customers, including prospective customers and employees; (iv) in the event that there is a change of control after which there is a material or detrimental change in the terms and conditions of employment, each executive director is entitled to terminate his employment and receive a payment equal to one-year's salary plus benefits, a pro rata share of his bonus up to the date of termination (plus, in the case of Dr David Ebsworth and Denis Mulhall, an additional bonus payment) and certain pension benefits; and (v) with effect from 1 October 2002, Dr Christopher Moyses' notice period was increased from six months to one year. Non-executive directors' letters of appointment With the exception of G. Kirk Raab, all non-executive directors are appointed for fixed three year periods under letters of appointment, which periods expire on the following dates: Name Expiry of appointment Dr Donald Drakeman 12/07/03 Dr James Hill 12/07/03 Professor Max Burger 09/05/04 Professor Raymond Dwek 09/05/04 John Rennocks 14/08/04 Directors' Compensation The following table provides summary information regarding the compensation paid to OGS directors as at 1 January 2003:

(1) With the exception of G. Kirk Raab, all non-executive directors are paid a fee of (pound)30,000 per annum plus (pound)500 for each committee meeting attended. (2) Professor Max Burger receives (pound)10,000 per annum for serving as the Chairman of OGS' Scientific Advisory Board ("SAB"). In addition, in 2002 Professor Burger received (pound)15,000 in recognition for providing services to the SABin respect of previous years. (3) Professor Raymond Dwek receives (pound)50,000 per annum in his capacity as a consultant to OGS. (4) For the year ended 31 December 2002, Dr James Hill received an additional fee of (pound)12,500 for serving as the Chairman of OGS' Development Committee. Compensation of Executive Directors The main components of compensation for the executive officers are annual salary, performance related bonuses and pension and other benefits. Executive directors receive annual salaries, which are set by the Compensation Committee and are generally effective as of 1 January each year. In determining the appropriate level for each executive director, the Compensation Committee considers both the nature and status of our operations and the responsibilities and performance of each executive director. Executive directors also qualify for a bonus, which is calculated as a percentage of annual salary and is dependent upon individual performance and achievement of individual and corporate goals. Finally, OGS currently operates an Executive Plan and a Sharesave Scheme in which executive directors may participate. Executive directors participate in a non-contributory defined contribution pension plan. All executive directors receive private health insurance for themselves and their immediate families and receive monthly allowances in lieu of company cars. Compensation of Non-executive Directors Apart from the fees payable to Professor Max Burger, Professor Raymond Dwek and Dr James Hill described above, the non-executive directors do not receive any remuneration from OGS other than their fees for services as members of the OGS Board. The level of fees is determined by the Chairman in consultation with the Chief Executive Officer. (b) New CAT Directors and Current OGS Directors who will not be appointed to the CAT Board Subject to the Merger becoming effective, Professor Rajesh Parekh and Dr David Ebsworth have agreed to serve as executive directors of CAT. Dr James Hill has agreed to serve as a non-executive director and Dr Christopher Moyses and Denis Mulhall will become members of the executive committee of CAT with effect from the same date. Dr James Hill's terms of appointment will remain unchanged. The service contracts of Dr David Ebsworth, Dr Christopher Moyses, Denis Mulhall and Professor Rajesh Parekh will remain unchanged, save as follows: (i) In relation to Dr Christopher Moyses, Denis Mulhall and Professor Rajesh Parekh, their existing service contracts provide that if there is a change of control of OGS and one of the events (the "Trigger Events") set out below occurs as a result of and within six months of such change of control, they are entitled to give three months' notice to terminate within 30 days of the Trigger Event occurring. Where such notice is given the directors are each entitled to a termination payment (the details of which are outlined in paragraph 6(a)(iv) above). (ii) The Trigger Events are where there has been a "material and detrimental change" to (i) the director's remuneration and terms and conditions without his agreement; (ii) the director's status without his agreement; or (iii) the director's benefits without compensation/agreement. (iii) In the case of Dr David Ebsworth, the change of control provision in his service contract provides that he may give three months' notice to terminate within 30 days of a change of control (without the need for any material or detrimental change to his status). He too is then entitled to a termination payment (the details of which are outlined in paragraph 6(a)(iv) above). (iv) CAT has agreed that, subject to the Merger becoming effective, the Trigger Events will cease to be a condition to the exercise of the change of control provisions for Dr Christopher Moyses, Denis Mulhall and Professor Rajesh Parekh and that the period for exercise of the change of control provisions in the service contracts of Dr David Ebsworth, Dr Christopher Moyses, Denis Mulhall and Professor Rajesh Parekh shall be extended so that the change of control provisions referred to above can be exercised at any point within the period of one year from the Effective Date. All of the other non-executive directors of OGS have agreed to resign from the Board of OGS following the Effective Date if requested by CAT. G.

Material contracts (a) CAT The following contracts, not being contracts entered into in the ordinary course of business, have been entered into by a member of the CAT Group within the two years immediately preceding the date of the commencement of the offer period (as defined in paragraph 4(e)(i) above) and are, or may be, material: (i) A support agreement dated 16 January 2002 (the "Support Agreement"), under which CAT agreed to make an offer (the "DRC Offer") for DRC through its wholly owned Canadian subsidiary CAT Canada which has since been wound up. The DRC Offer was made in accordance with the terms of the Support Agreement on 1 February 2002 with an initial expiry date of 12 March 2002. However, a competing proposal was received by DRC prior to the expiry of the DRC Offer which the board of directors of DRC considered to be superior to the DRC Offer. Accordingly DRC terminated the Support Agreement with CAT in accordance with its terms and entered into a new support agreement with the competing bidder. CAT extended the expiry time of the DRC Offer to 26 April 2002 notwithstanding that it no longer had the support of DRC. The DRC Offer expired on 26 April 2002 with the minimum tender condition not having been met. (ii) Concurrent with entering into the Support Agreement, CAT entered into a lock-up agreement (the "Lock-Up Agreement") with MDS Capital Corp., Canadian Medical Discoveries Fund Inc. and The Health Care and Biotechnology Venture Fund (together, the "Locked-Up Shareholders") dated 16 January 2002 pursuant to which the Locked-Up Shareholders agreed to accept CAT's offer for their DRC shares and tender to the DRC Offer. Upon the termination of the Support Agreement by DRC, the Locked-Up Shareholders terminated the Lock-Up Agreement in accordance with its terms and entered into a new lock-up agreement with the competing bidder. (iii) In connection with entering into the Support Agreement CAT, CAT Limited and DRC entered into an amending deed dated 16 January 2002 pursuant to which the royalty agreement between CAT Limited and DRC dated 31 March 1994 (the "Royalty Agreement") was amended to permit CAT to terminate the Royalty Agreement in certain circumstances in the event of a change of control of DRC upon written notice. As a result of the successful bid for DRC by the competing bidder, a change of control occurred and CAT terminated the Royalty Agreement with DRC on 30 April 2002. In accordance with the terms of the amending deed, CAT made a C$14 million (14 million Canadian dollars) termination payment to DRC through the allotment of 463,818 CAT Shares. Under the terminated Royalty Agreement with DRC, DRC was entitled to a percentage of the cash receivable by CAT in respect of revenues from contracts and products and, in the case of contracts or commercial transactions concerning products where a corporate partner subscribes for share capital or instruments convertible into share capital ("equity"), the value of that equity. DRC's rights, as described above, would have continued until 13 November 2009, with the percentage of cash receivable to which DRC is entitled reducing over time. Until 30 September 2004, DRC would have been entitled to 3.5 per cent., declining to 2.5 per cent. until 13 November 2009. (iv) A sponsorship agreement between CAT and Merrill Lynch dated 1 February 2002, under which CAT agreed to appoint Merrill Lynch as sponsor to CAT in connection with the DRC Offer, which provided for the payment by CAT of all expenses incurred by Merrill Lynch in connection with the admission to the Official List of the CAT Shares which would have been issued under the DRC Offer had that offer been successful. (v) An agreement dated 1 February 2002, between CAT and Merrill Lynch Canada, Inc. (the "Dealer Manager") under which the Dealer Manager was retained as financial adviser and to act as dealer manager in connection with the DRC Offer. The Dealer Manager undertook to form a soliciting dealer group comprised of members of the Investment Dealers Association of Canada and members of the stock exchanges in Canada to solicit acceptances of the DRC Offer. (vi) The Merger Agreement, which sets out provisions relating to the implementation of the Merger and imposes an obligation on both parties to use their reasonable endeavours to achieve the satisfaction of the conditions set out in paragraph 1 of Part IV of this document and to meet the timetable for implementation of the Scheme which has been agreed between the parties. The Merger Agreement provides that CAT shall only be entitled to invoke a condition to the Merger if the Panel has determined that it is entitled to do so. The parties have agreed that OGS shall only be entitled to invoke a condition to the Merger in circumstances where it would be able to invoke the condition in question if it were an offeror for CAT in an offer governed by the City Code. (vii) An inducement fee agreement dated 22 January 2003 between CAT and OGS. Pursuant to the agreement each party has agreed to pay the sum of (pound)1,096,292 to the other party in the event that: (a) its shareholders fail to pass any shareholder resolution required to implement the Merger; or (b) its board of directors fails to recommend or withdraws or modifies it recommendation of the Merger or fails to take any steps which are necessary to implement the Merger (including failing to put any shareholders resolutions to the vote or adjourning or permitting the adjournment of any meetings at which such resolutions are to be put). The inducement fee referred to above will not be payable in circumstances where the relevant party is entitled to invoke a condition to the Merger in accordance with the Merger Agreement. (viii) A non-solicitation agreement dated 22 January 2003 between CAT and OGS. Pursuant to this agreement OGS has given certain undertakings relating to the non-solicitation of any third party alternative offer, or other merger transaction and restrictions and discussions or negotiation with, and the provision of information to, any third party in connection with any such alternative offer or other merger transaction. (ix) A sponsorship agreement between CAT and Merrill Lynch dated 3 February 2003, pursuant to which CAT agreed to appoint Merrill Lynch as sponsor to CAT in connection with the application for listing of the New CAT Shares and the issue of the accompanying Listing Particulars. The sponsorship agreement provides for the payment by CAT of all expenses incurred by Merrill Lynch in connection with the admission to the Official List of the New CAT Shares and contains: (a) certain warranties by CAT as to the accuracy of the information contained in these Listing Particulars; (b) an indemnity from CAT to Merrill Lynch; and (c) certain undertakings from CAT relating, inter alia, to consultation with and the provision of information to, Merrill Lynch in its capacity as sponsor.
