Acquisition(s)

NOT FOR RELEASE, PUBLICATION OR DISTRIBUTION, IN WHOLE OR IN PART, IN OR INTO OR FROM ANY JURISDICTION WHERE TO DO SO WOULD CONSTITUTE A VIOLATION OF THE RELEVANT LAWS OF SUCH JURISDICTION London, 9 January 2009 RECOMMENDED ALL SHARE OFFER by Avacta Group plc("Avacta") for Curidium Medica plc("Curidium") (TO BE EFFECTED BY MEANS OF A SCHEME OF ARRANGEMENT) Summary The boards of Avacta and Curidium are pleased to announce that they have today reached agreement on the terms of a recommended all share offer (the "Recommended Offer") by Avacta for the entire issued and to be issued ordinary share capital of Curidium. The combination of Avacta with Curidium is intended to create a stronger diagnostics business within the Enlarged Group delivering new technology and tests in the important areas of point-of-care human diagnostics and personalised medicine. The boards of Avacta and Curidium believe that the business of the Enlarged Group will benefit from the combination of Avacta's expertise in developing new technology products and services, and its ability to commercialise diagnostics intellectual property, with Curidium's expertise in the biology of disease and personalised medicine, underpinned by Curidium's existing cash resources. The Enlarged Group will have opportunities to generate long term value in specialised fields as well as near term opportunities for revenue growth through: * Avacta's current contract services business and imminent first product launches; * Curidium's development of diagnostic tests in schizophrenia and its commercial partnership with Takeda Research International Inc to develop similar diagnostic tests in major depressive disorder; * opportunities to commercialise diagnostic tests through Avacta's contract services business, and through the development of novel diagnostic technologies to deliver tests in the clinic or at home; * accelerating the development of some of Avacta's prognostic and diagnostic products by applying Curidium's expertise in biostatistics and bioinformatics with the aim of getting these products to market sooner, and * the expertise of the Enlarged Group in delivering solutions to the high value problem of rescuing failed drug compounds for pharmaceutical companies. It is proposed that the Recommended Offer be implemented by way of a scheme of arrangement under part 26 of the Companies Act 2006. Under the terms of the Recommended Offer, Scheme Shareholders will receive: 14.5 New Avacta Shares for every 1 Scheme Share held at the Scheme Record Time and so in proportion for any other number of Scheme Shares held at the Scheme Record Time. Based upon the Closing Price of 2.25 pence per Avacta Share on 8 January 2009 (being the Business Day prior to this document), the Recommended Offer values each Curidium Share at 32.6 pence and Curidium's Existing Share Capital at approximately £6.18 million. On this agreed basis, the Recommended Offer represents a premium of 20.7 per cent. to the Closing Price of a Curidium Share of 27 pence on 8 January 2009 (being the Business Day prior to this announcement). Assuming no further Avacta Shares are issued in the period between the date of this announcement and the Effective Date, immediately following the Effective Date approximately 25 per cent. of the enlarged issued ordinary share capital of Avacta will be held by former Curidium Shareholders and approximately 75 per cent. will be held by existing Avacta Shareholders. The Recommended Offer will be conditional on, amongst other things, the approval of the Avacta Shareholders and the approval of Curidium Shareholders. The Curidium Directors, who have been so advised by J M Finn Capital Markets Limited ("FinnCap"), consider the terms of the Recommended Offer to be fair and reasonable. In providing its advice, FinnCap has taken into account the commercial assessments of the Curidium Directors. The Avacta Directors intend unanimously to recommend that Avacta Shareholders vote in favour of the Avacta Resolutions at the Avacta General Meeting and the Curidium Directors intend unanimously to recommend that Curidium Shareholders vote in favour of the Scheme at the Court Meeting and the Curidium Resolutions at the Curidium General Meeting. Avacta has received irrevocable undertakings to vote in favour of the Scheme and the Curidium Resolutions from each of the Curidium Directors who collectively hold 4,128,156 Curidium Shares, representing approximately 21.8 per cent. of Curidium's Existing Share Capital. In addition certain investors have irrevocably undertaken to vote in favour of the Scheme and the Curidium Resolutions in respect of, in aggregate, 8,804,214 Curidium Shares, representing 46.5 per cent. of Curidium's Existing Share Capital. Accordingly Avacta has received undertakings to vote in favour of the Scheme and the Curidium Resolutions from the holders of, in aggregate, 12,932,370 Curidium Shares, representing approximately 68.3per cent. of Curidium's Existing Share Capital. In addition, Avacta has received irrevocable undertakings to vote in favour of the Avacta Resolutions at the Avacta General Meeting from the Avacta Directors who hold Avacta Shares in respect of their entire holding of Avacta Shares amounting to, in aggregate, 194,582,525 Avacta Shares, representing approximately 23.6 per cent. of the existing issued share capital of Avacta. The Scheme Document setting out further details of the Recommended Offer and the procedures to be followed in connection with the implementation of the Scheme will be posted to Curidium Shareholders as soon as reasonably practicable. The Acquisition is expected to be completed in March 2009. Dr. Alastair Smith, Chief Executive Officer of Avacta, commented: "The merger of Curidium and Avacta will strengthen the Enlarged Group's ability to deliver a range of commercially valuable and clinically effective diagnostic products. The point-of-care testing and personalised medicine markets offer high value and high growth opportunities and the combined strengths of Avacta and Curidium will put us in a strong position to capitalise on these opportunities." Dr. Barry Porter, Chairman of Curidium, added: "The combination of Avacta and Curidium creates an entity that will have significant potential in the diagnostics field.

NOT FOR RELEASE, PUBLICATION OR DISTRIBUTION, IN WHOLE OR IN PART, IN OR INTO OR FROM ANY JURISDICTION WHERE TO DO SO WOULD CONSTITUTE A VIOLATION OF THE RELEVANT LAWS OF SUCH JURISDICTION London, 9 January 2009 RECOMMENDED ALL SHARE OFFER by AVACTA GROUP PLC ("AVACTA") for CURIDIUM MEDICA GROUP PLC ("CURIDIUM") (TO BE EFFECTED BY MEANS OF A SCHEME OF ARRANGEMENT) 1. Introduction The boards of Avacta and Curidium are pleased to announce that they have today reached agreement on the terms of a recommended all share offer (the "Recommended Offer") by Avacta for the entire issued and to be issued ordinary share capital of Curidium. It is proposed that the Recommended Offer be implemented by way of a scheme of arrangement under part 26 of the Companies Act 2006. The combination of Avacta with Curidium is intended to create a stronger diagnostics business within the Enlarged Group delivering new technology and tests in the important areas of point-of-care diagnostics and personalised medicine. The Avacta Directors and the Curidium Directors believe that the business of the Enlarged Group will benefit from the combination of Avacta's expertise in developing new technology products and services, and its ability to commercialise diagnostics intellectual property with Curidium's expertise in the biology of disease and personalised medicine. The Enlarged Group will have opportunities to generate longer term value in specialised fields as well as near term opportunities for revenue growth from Avacta's current contract services business and imminent first product launches. It will continue to focus on Curidium's development of diagnostic tests and its commercial partnership with Takeda Research International Inc to develop similar tests in major depressive disorder whilst seeking opportunities to commercialise diagnostic tests through Avacta's contract services business, and through the development of novel diagnostic technologies to deliver tests in the clinic or at home. The Avacta Directors believe that the combination of Curidium's expertise in biostatistics and bioinformatics should accelerate the development of some of Avacta's prognostic and diagnostic products to reach market sooner. Further, the Avacta Directors believe that the Enlarged Group will also be in a strong position to address the high value problem of rescuing failed drug compounds for pharmaceutical companies. The Curidium Directors, who have been so advised by FinnCap, consider the terms of the Recommended Offer to be fair and reasonable. In providing its advice, FinnCap has taken into account the commercial assessments of the Curidium Directors. Accordingly, the Curidium Directors unanimously intend to recommend Curidium Shareholders to vote in favour of the Scheme at the Court Meeting of the Curidium Shareholders and in favour of the Curidium Resolutions to be proposed at the Curidium General Meeting, as they have irrevocably undertaken to do in respect of their own beneficial holdings of 4,128,156 Curidium Shares, representing, in aggregate, approximately 21.8 per cent. of the Curidium Shares in issue on 8 January 2009 being the last Business Day prior to the date of this announcement. 2. The Recommended Offer The Recommended Offer involves the acquisition by Avacta of the entire issued and to be issued ordinary share capital of Curidium and is to be effected by way of a scheme of arrangement between Curidium and Scheme Shareholders under part 26 of the Companies Act 2006. Under the terms of the Scheme, which will be subject to satisfaction or (where appropriate) waiver of the Conditions set out in Appendix I and to the further terms to be set out in the Scheme Document, Scheme Shareholders who are on the register of members at the Scheme Record Time will receive: 14.5 New Avacta Shares for every 1 Scheme Share and so in proportion for any other number of Scheme Shares held at the Scheme Record Time. Fractions of New Avacta Shares will not be allotted or issued pursuant to the Recommended Offer and fractional entitlements will be rounded down to the nearest whole number of New Avacta Shares. Based upon the Closing Price of 2.25 pence per Avacta Share on 8 January 2009 (being the Business Day prior to this announcement), the Recommended Offer values each Curidium Share at 32.6 pence and Curidium's Existing Share Capital at approximately £6.18 million. On this agreed basis, the Recommended Offer represents a premium of 20.7 per cent. to the Closing Price of a Curidium Share of 27 pence on 8 January 2009 (being the Business Day prior to this announcement). Assuming no further Avacta Shares are issued in the period between the date of this announcement and the Effective Date, immediately following the Effective Date approximately 25 per cent. of the enlarged issued ordinary share capital of Avacta will be held by former Curidium Shareholders and approximately 75 per cent. will be held by Avacta Shareholders. If the Scheme becomes effective, it will be binding on all Curidium Shareholders irrespective of whether or not they attended or voted in favour of the resolutions at the Court Meeting or the Curidium General Meeting. The New Avacta Shares will be issued credited as fully paid, and on identical terms to and will rank pari passu with the existing Avacta Shares, including the right to receive and retain all dividends and other distributions declared, paid or made on Avacta Shares after the Scheme becomes effective. 3. Background to, and reasons for, Avacta's Recommended Offer Rationale for the combination of Avacta and Curidium Avacta and Curidium are both developing diagnostic products aimed at the emerging diagnostics markets in point-of-care testing and personalised medicine. Diagnostic products for these markets generally combine a biological test for the presence of one or more biomarkers of disease with a means of delivering that test to the patient. Curidium has expertise in developing biological tests, which the Avacta and Curidium Directors believe stongly fits with Avacta's services and technology products that can be used to commercialise such expertise. Avacta has identified significant potential markets in point-of-care diagnostic technology and is currently seeking to develop new and powerful diagnostic technologies to address these market needs. The development of Avacta's first diagnostic products - a rapid immunoassay system and a breath diagnostics technology - will benefit from the type of biostatistical expertise in biomarker pattern recognition which is fundamental to Curidium's technology - "Homomatrix". The skills to develop these advanced data analysis methods are currently being developed by Avacta and Curidium's established expertise should accelerate Avacta's data analysis programmes. Avacta intends to grow its diagnostics product revenues by partnering with diagnostics companies that have established biological tests, for example a blood test to identify food allergies, which they want to provide at the point-of-care for reasons of improved patient outcomes or improved business performance. Avacta has hitherto adopted this plan because it does not have in-house expertise in developing the biological tests themselves. However, Avacta believes that acquiring biological tests and Curidium's expertise to develop them in-house and combining these with the technology or services to deliver those tests represents an attractive opportunity. Near term opportunities and long term value The Curidium Directors believe that Curidium has the potential to deliver significant long term value in human diagnostics in the central nervous system ("CNS") area. Avacta has focused on near term markets by developing prognostic tests that could be used by biopharmaceutical developers, to help them get their products to market quicker and more cheaply, and in the veterinary diagnostics market where regulatory hurdles are much lower than in the human healthcare applications. Avacta believes that the skills in bioinformatics and biostatistics within Curidium can be applied in both of these areas and that there is an immediate, opportunity for these skills to accelerate the prognostic biopharmaceutical testing product in the near term. The Curidium Directors believe that the human diagnostics market offers significant opportunities for long term value generation. Further they believe that whilst Avacta has strengths in developing technology products that can commercialise diagnostic tests by delivering them to patients, Curidium's experience and knowledge of the healthcare markets and the biology of disease will be of value in contributing to the strategic development of the combined diagnostics business and identification of additional opportunities. Consolidation and sustainable growth Consolidation of the two diagnostics businesses, underpinned by Curidium's existing cash resources, current revenues from Avacta's contract services business and future revenues from its first two technology products, will create an Enlarged Group with both immediate revenue and the potential for substantial growth in the longer term. 4. Recommendation The Curidium Directors, who have been so advised by FinnCap, consider the terms of the Offer to be fair and reasonable. In providing its advice, FinnCap has taken into account the Curidium Directors' commercial assessments. Accordingly, the Curidium Directors intend unanimously to recommend that Curidium Shareholders vote in favour of the Scheme and the Curidium Resolutions. 5. Directors, Management and Employees Upon the Scheme becoming effective, Barry Porter will join the Enlarged Group's board as a non-executive director. The Curidium Directors have all agreed to resign from the board of Curidium on the date on which the Scheme becomes effective. It is intended that Alastair Smith and Tim Sykes will be appointed to the board of Curidium on the date on which the Scheme becomes effective. As a result of the Scheme, Avacta intends to establish an operating board for the Enlarged Group which Anne Bruinvels and Smita Price will join. In addition it is expected that Ann Hayes will make her services available to the Enlarged Group in a consultancy capacity. Simon Webster, Kurt Baldwin and Russell Hodgetts who are currently directors of Avacta will resign from the board of Avacta upon the Scheme becoming effective and join the Enlarged Group's newly created operating board. Further details of the termination arrangements, modification of terms and consultancy arrangements will be set out in the Scheme Document. Avacta has given assurances that, following the Scheme becoming effective, the existing employment rights, including accrued pension rights, of Curidium's employees will be fully safeguarded and, save as in the case of the Curidium Directors as referred to above, its plans for Curidium do not include any material changes in the terms and conditions of employment of Curidium employees. 6. Information on Avacta Avacta seeks to provide solutions to high value problems in Life Sciences markets through innovative products and expert contract services. Avacta is focused on opportunities in two large Life Sciences sub-sectors: biopharmaceuticals and diagnostics. The Avacta Group is working to equip biopharmaceutical developers with tools to get their drugs to market earlier and at a lower cost, and to optimise the performance of those products. Avacta's technology devices and services are designed to assist drug developers to analyse their compounds in much greater detail and at an earlier stage in the drug development cycle than currently possible, thereby providing timely identification of problems that can cause costly late stage failures or poor performance. Avacta's first product for market, "Optim" - a benchtop protein analyser, is expected to be launched early this year. Avacta has developed its own route to market for this product, through its contract services business, an ISO 9001 registered operation which provides high end analytical contract services to the biopharmaceutical, pharmaceutical and healthcare industries specialising in its core strengths of biophysical analysis, spectroscopy and microscopy. Avacta's laser analysis and automated fluid handling technology also provide solutions to unmet needs in diagnostics markets for rapid point-of-care testing and Avacta believes that this is a market that will play a key role in driving commercial progress and shareholder value. Avacta's technologies currently in development include a rapid immunoassay system, "MIDAS", and a laser based breath analysis technology. Both of these technologies can be applied equally in animal and human diagnostics markets and Avacta has chosen to focus its early commercial efforts in the veterinary diagnostics sector because of the lower regulatory hurdles in this market compared with human diagnostics. This strategy is intended to generate nearer term revenues whilst providing opportunities to rigorously validate new technologies before moving to human healthcare applications. Avacta has a commercial partner for its first veterinary diagnostics test product which is expected to be launched in the middle of this year. Additionally Avacta is seeking to commercialise its technologies through licensing opportunities with partners in the homeland security/defence and industrial gas sensing markets to generate further near term revenues to support the longer term development of its products. Avacta has secured two commercial partners in the area of industrial gas sensing to co-develop two new products. Based in York, UK, Avacta occupies purpose built laboratories at the Biocentre in the University Science Park and employs approximately thirty people. 7. Information on Curidium Curidium is focused on identifying targeted medicines and companion diagnostics to treat patients more effectively. Curidium aims to more accurately define patient subpopulations and to identify targeted drug therapies for these subgroups. Curidium has used its proprietary technology, Homomatrix®, to identify what the Curidium Directors believe to be a potential companion diagnostic for schizophrenia and bipolar affective disorder. The test, called PsychINDx™, may be used to sub-classify patients into four subgroups, which are characterized by distinct gene expression profiles. The Curidium Directors believe that Curidium's proprietary technology, has the potential to uncover underlying disease mechanisms and to separate heterogeneous patient populations into more homogeneous subgroups based on gene expression profiles. Homomatrix® can be applied to investigate a number of human diseases. Curidium is working with Takeda Research Investment Inc. to apply Curidium's platform, Homomatrix®, to develop and license diagnostic tests and other intellectual property to aid with drug development and discovery in the disease area of major depressive disorder. 8. Current trading and prospects of the Enlarged Group Avacta Avacta is generating revenues through its contract services business, which provides high end analytical contract services to the pharmaceutical and healthcare materials sectors. In the financial year ended 31 July 2008, revenue growth within the contract services business was 120% at £0.47 million (2007: £ 0.21 million). The operating loss of the Avacta Group was £1.65 million (2007: loss £1.27 million) and the Avacta Group had cash at bank of £1.10 million (2007: £2.53 million). Losses before tax of the Avacta Group were £1.57 million (2007 : loss £1.22 million) and the loss per share remained flat at 0.18p (2007: loss 0.18p). The pipeline and work in progress within the contract services business is encouraging whilst product launches remain on track, as set out above. Avacta has made considerable progress during the past year having continued to meet the commercial and developmental targets set at the time of the admission to AIM in August 2006. The Avacta Group's overall objective is to bring technology products to market and deliver high value contract services, based on unique in-house technologies and expertise, which enable the very early stage identification and analysis of drug compounds, chemicals or organisms. Such technologies have commercial relevance in a range of high value sectors, notably drug development, point-of-care medical diagnosis and defence and security. The Avacta Group's lead product, Optim, is expected to launch in the early part of this year andAvacta's first diagnostics product, MIDAS, into the veterinary market shortly afterwards, ahead of schedule. With these product launches and a pipeline of future product developments over the coming few years, Avacta is making strong progress towards its target to become a leading provider of high value technology products and services to the broad Life Sciences sector. Curidium Curidium's unaudited revenue for the six months ended 30 June 2008 was nil (audited year ended 31 December 2007: nil). In the same period unaudited expenditure on Research and Development activities was £0.25 million (audited year ended 31 December 2007: £0.39 million). The unaudited operating loss for the Curidium Group was £0.57 million (audited year ended 31 December 2007: £1.3 million). In the first half of 2008 Curidium introduced PsychINDxTM, its diagnostic blood test to sub-classify patients with schizophrenia or bipolar disorder, to multinational pharmaceutical companies. Further product development initiatives to strengthen PsychINDxTM have commenced with the aim of enhancing the test's attractiveness to potential customers. The Curidium Directors believe that Curidium's work in major depressive disorder, in partnership with Takeda Research Investment Inc., is progressing well and the Curidium Group is applying its Homomatrix® technology to brain tissue samples sourced by the Company. As a pre revenue company with ongoing research and development costs and expenditure, the Curidium Group continues to manage cash resources and as at 30 June 2008 had unaudited cash balances and other financial assets of £3.6 million (as at 31 December 2007 £4.2 million audited). Prospects for the Enlarged Group The Avacta Directors believe that the combination of the complementary skills and expertise within the two businesses, a stronger balance sheet underpinned by near term revenue generation through services and products, will provide the Enlarged Group with excellent prospects to build a high value and long term sustainable diagnostic and detection business. The Avacta Directors believe that there is potential to accelerate the scale of the Enlarged Group via strategic acquisitions. The Avacta Directors have identified a private company which operates within the veterinary diagnostics services market with which Avacta intends to launch MIDAS. The Directors believe this company will benefit from the ability of the Enlarged Group to grow its business by developing and delivering new diagnostic service and will also provide the Enlarged Group with a direct sales channel for its first diagnostics products. Avacta has signed heads of terms to acquire this company and is in the process of carrying out due diligence. The consideration for this acquisition is expected to be approximately £0.8 million, which will be payable in cash. 9. Structure of the Acquisition and shareholder meetings It is intended that the Acquisition will be implemented by way of a scheme of arrangement between Curidium and the Scheme Shareholders under part 26 of the Companies Act 2006 (including a reduction of capital under section 135 of the Companies Act 1985). The purpose of the Scheme is to allow Avacta to become the owner of the entire issued ordinary share capital of Curidium. The procedure involves an application by Curidium to the Court to sanction the Scheme, the cancellation of the Scheme Shares held by the Scheme Shareholders, the application of the reserve arising from such cancellation in paying up in full a number of new ordinary shares in Curidium (which is equal to the number of the Scheme Shares cancelled) and issuing those new shares to Avacta in consideration for which the Scheme Shareholders will receive New Avacta Shares on the basis set out in paragraph 2 of this announcement. The implementation of the Scheme is subject to satisfaction or (where appropriate) waiver of all the Conditions set out in Appendix I and the further terms to be set out in the Scheme Document. Implementation of the Scheme is subject, amongst other things, to the approval of a majority in number of the Scheme Shareholders present and voting in person or by proxy at the Court Meeting and which represent not less than 75 per cent. in value of the Scheme Shares voted by the Scheme Shareholders at the Court Meeting. Implementation of the Scheme will also require the passing of the Curidium Resolutions, requiring the approval of Curidium Shareholders representing at least 75 per cent. of the votes cast at the Curidium General Meeting. Application will shortly be made to the Court for leave to convene the Court Meeting which (subject to the approval of the Court) is expected to be held at 12 noon on 11 February 2009. It is expected that the Curidium General Meeting will be convened at 12.30pm (or as soon thereafter as the Court Meeting is concluded or adjourned) on 11 February 2009. In order for Avacta to obtain the necessary shareholder approvals required in connection with the issue of the New Avacta Shares, the Acquisition is also conditional upon the Avacta Shareholders passing the Avacta Resolutions at the Avacta General Meeting, which is expected to be held at 10.00am on 9 February 2009. Following the Meetings, the Scheme and the Reduction of Capital will only become effective once the Court sanctions the Scheme and confirms the Reduction of Capital and copies of the Court Orders have been delivered to the Registrar of Companies in England and Wales and, in the case of the Reduction of Capital upon the Reduction Court Order being registered by the Registrar of Companies together with a minute of the Reduction of Capital. The Scheme is also conditional on Admission occurring. Once the Scheme becomes effective, it will be binding on all Curidium Shareholders whether or not they attended or voted at the Court Meeting or the Curidium General Meeting. The Scheme Document setting out full details of the Acquisition and the Scheme, together with notices of the Court Meeting and the Curidium General Meeting will be posted as soon as practicable to Curidium Shareholders. At the same time, Avacta will post the Avacta Circular, containing a notice convening the Avacta General Meeting to Avacta Shareholders. Curidium is also proposing to cancel its 0.9 pence deferred shares in issue and its 24 pence deferred shares in issue in accordance with their terms as set out in Curidium's Articles of Association. The cancellation will be effected by a reduction of capital under section 135 of the Companies Act 1985 and will require the approval of the Curidium Shareholders at the Curidium General Meeting by a special resolution. 10. Implementation, Non-Solicitation and Inducement Fee Agreement Curidium and Avacta have entered into an agreement ("Implementation Agreement") dated 8 January 2009 in connection with the Acquisition, pursuant to which each of the parties has undertaken, among other things, and, as promptly as practicable, to take or cause to be taken all such reasonable steps as are within their respective powers and necessary to implement the Scheme. Each of the parties has agreed that prior to the Scheme becoming effective or the Implementation Agreements being terminated in accordance with its terms (whichever is earlier), each of Curidium and Avacta will conduct their respective businesses in the ordinary and normal course and not do or omit to take any action which will or would reasonably be expected to result in any of the Conditions not being satisfied. As an inducement to Avacta proceeding with the Recommended Offer, Curidium has agreed to pay Avacta an inducement fee of £61,802 (inclusive of any irrecoverable VAT) if: i. a Competing Proposal in relation to Curidium is announced which is recommended by the Curidium Directors; ii. the Curidium Directors withdraw or modify their recommendation of the Recommended Offer; iii. there is a material breach by Curidium of certain undertakings relating to the implementation of the Scheme; iv. any matter requiring the consent of Curidium Shareholders under Rule 21 of the City Code occurs without the consent of Avacta; v. the Curidium Resolutions required to implement the Acquisition are not passed with the requisite majorities; or vi. the resolutions required to implement the Acquisition are passed and the Scheme does not become effective within 6 weeks of such date by virtue of a failure of Curidium or the failure of the Court to sanction the Scheme. The obligation of Curidium to pay the inducement fee ceases if: i. Curidium does not proceed with the Recommended Offer by virtue of it identifying a material issue affecting the Avacta Group in the course of its due diligence on the Avacta Group; or ii. Avacta seeks to materially and adversely alter the terms of the Recommended Offer; or iii. the Scheme becomes effective. As an inducement to Curidium proceeding with the Recommended Offer, Avacta has agreed to pay Curidium an inducement fee of £61,802 (inclusive of any irrecoverable VAT) if: i. the Avacta Shareholders do not pass the Avacta Resolutions at the Avacta General Meeting; ii. Avacta notifies Curidium that it wishes to materially and adversely change the terms of the Recommended Offer or that it is not willing or able to proceed with the Recommended Offer (other than by virtue of a material issue arising out of the due diligence undertaken on the Curidium Group); or iii. Curidium is not willing to proceed with the Recommended Offer by virtue of Curidium identifying a material issue in the course of its due diligence on the Avacta Group. The obligation of Avacta to pay the inducement fee ceases if Avacta does not proceed with the Recommended Offer by virtue of it identifying a material issue affecting the Curidium Group in the course of its due diligence on the Curidium Group. However, nothing in the Implementation Agreement shall oblige Curidium or Avacta to pay any amount which the Panel would determine would not be permitted by Rule 21.2 of the Code. Curidium has also agreed that until the Scheme has become unconditional or lapsed it shall not solicit or invite enquiries, proposals or offers relating to an offer for the Curidium Shares from a third party. 11. Irrevocable undertakings Avacta has received irrevocable undertakings to vote in favour of the resolutions at the Court Meeting and the Curidium General Meeting from each of the Curidium Directors in respect of their entire legal and beneficial holdings of Curidium Shares and those of their connected and related persons amounting, in aggregate, to 4,128,156 Curidium Shares, representing approximately 21.8 per cent. of Curidium's Existing Share Capital . These undertakings will continue to be binding even in the event of a higher competing offer for Curidium being announced, and cannot be withdrawn other than in the event of the Scheme lapsing or being withdrawn. In addition certain investors have irrevocably undertaken to vote in favour of the resolutions at the Court Meeting and the Curidium General Meeting in respect of, in aggregate, 8,804,214 Curidium Shares, representing 46.5 per cent. of Curidium's Existing Share Capital. Save for the irrevocable undertaking given by Gartmore Investment Limited, these irrevocable undertakings will continue to be binding on such persons even in the event that a third party makes a higher competing offer for Curidium and cannot be withdrawn other than in the event of the Scheme lapsing or being withdrawn. The irrevocable given by Gartmore Investment Limited will cease to be binding in the event that a Compteting Proposal is announced pursuant to Rule 2.5 of the City Code and which in the reasonable opinion of Gartmore Investment Limited represents an increase of more than 10 per cent. to the value of the Recommended Offer. Accordingly Avacta in aggregate has received undertakings to vote in favour of the resolutions at the Court Meeting and the Curidium General Meeting from the holders of 12,932,370 Curidium Shares representing approximately 68.3 per cent. of Curidium's Existing Share Capital. Avacta has received irrevocable undertakings to vote in favour of the Avacta Resolutions at the Avacta General Meeting from the Avacta Directors who hold Avacta Shares in respect of their entire holding of Avacta Shares amounting to, in aggregate, 194,582,525 Avacta Shares, representing approximately 23.6 per cent. of the existing issued share capital of Avacta. Particulars of these irrevocable undertakings are contained in Appendix III to this announcement. 12. Curidium Share Schemes and the Curidium Warrants The Scheme will extend to any Curidium Shares that are unconditionally allotted or issued pursuant to the exercise of options or vesting of awards under the Curidium Share Schemes, or the exercise of the Curidium Warrants, in each case on or prior to the Scheme Record Time. Appropriate proposals will be made to participants in the Curidium Share Schemes and to the holders of the Curidium Warrants at the same time as the Scheme Document is posted to Scheme Shareholders or as soon as possible thereafter. Details of these proposals will be set out in the Scheme Document and in separate letters to be sent to participants in the Curidium Share Schemes and the holders of the Curidium Warrants. 13. Settlement, listing and dealings Prior to the Scheme becoming effective, Curidium will make an application to the London Stock Exchange for the cancellation of the Curidium Shares from trading on AIM. Accordingly, if the Scheme is sanctioned by the Court and the other conditions to the Scheme are waived or satisfied, it is expected that the Curidium Shares will cease to be traded on AIM on or before 8.00 a.m. on the first Business Day following the Effective Date and that the last day of dealings in Curidium is expected to be on 2 March 2009. On the Effective Date, share certificates in respect of Curidium Shares will cease to be valid and should, if so requested by Curidium, be sent to Curidium for cancellation. In addition, on the Effective Date entitlements to Curidium Shares held within the CREST system will be cancelled. It is proposed that following the Effective Date and after its shares have been delisted, Curidium will be re-registered as a private limited company. The New Avacta Shares are to be issued in registered form. Settlement of the New Avacta Shares to which Curidium Shareholders are entitled is expected to occur as soon as possible after the Effective Date and in any event within 14 days of the Effective Date. 14. Overseas Curidiumshareholders CuridiumShareholders who are resident in, ordinarily resident in, or who are citizens of any jurisdiction outside the UK ("Overseas CuridiumShareholders") should consult their independent professional advisers as to whether they require any governmental or other consents or need to observe any other formalities to enable them to participate in the Recommended Offer. If a CuridiumShareholder is in any doubt as to his eligibility to participate in the Recommended Offer, he should contact his independent professional adviser immediately. The implications of the Scheme for Overseas Curidium Shareholders may be affected by the laws of the relevant jurisdictions. Such Overseas Curidium Shareholders should inform themselves about and observe any applicable legal requirements. It is the responsibility of each Overseas Curidium Shareholder to satisfy himself as to the full observance of the laws of the relevant jurisdiction in connection therewith, including the obtaining of any governmental, exchange control or other consents which may be required to be observed and the payment of any issue, transfer or other taxes in such jurisdictions. 15.

Disclosure of interests in CuridiumShares Save as disclosed below, as at the time of this announcement neither Avacta (nor any of its directors) nor, so far as Avacta is aware, any person acting in concert with Avacta, has any interest in, any right to subscribe for, or has borrowed or lent any Curidium Shares or any securities convertible or exchangeable into Curidium Shares ("Relevant Securities"), nor does any such person hold any short positions in relation to Relevant Securities (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, nor does any such person have any arrangement in relation to Relevant Securities. For these purposes, "arrangement" includes any indemnity or option arrangement, any agreement or understanding, formal or informal, of whatever nature, relating to Relevant Securities which may be an inducement to deal or refrain from dealing in such securities.

Any such additional interest(s) or dealing(s) will be discussed with the Panel and, if appropriate, will be disclosed in the Scheme Document or announced if requested by the Panel. 17.

Cautionary note on forward looking statements This announcement contains certain forward-looking statements with respect to the financial condition, results of operations and business of Avacta and Curidium and certain plans and objectives of the Avacta Directors and the Curidium Directors with respect thereto. These forward-looking statements can be identified by the fact that they do not relate only to historical or current facts. Forward-looking statements often use words such as "anticipate", "target", "expect", "estimate", "intend", "plan", "goal", "believe", "will", "may", "should", "would", "could" or other words of similar meaning. These statements are based on assumptions and assessments made by the Avacta Directors and/or the Curidium Directors in light of their experience and their perception of historical trends, current conditions, expected future developments and other factors they believe appropriate. 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 and the factors described in the context of such forward-looking statements in this announcement could cause actual results and developments to differ materially from those expressed in or implied by such forward-looking statements. Although the Avacta Directors and the Curidium Directors believe that the expectations reflected in such forward-looking statements are reasonable, they can give no assurance that such expectations will prove to have been correct and assume no obligation to update or correct the information contained in this document and Avacta and Curidium therefore caution you not to place undue reliance on these forward-looking statements which speak only as at the date of this announcement. Nothing in this announcement is intended to be a profit forecast and the statements in this announcement should not be interpreted to mean that the earnings per Avacta Share for the current or future financial periods will necessarily be greater than those for the relevant preceding financial period. 19. Dealing disclosure requirements Under the provisions of Rule 8.3 of the Code, if any person is, or becomes, "interested" (directly or indirectly) in 1 per cent. or more of any class of "relevant securities" of Avacta or of Curidium, all "dealings" in any "relevant securities" of that company (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 pm (London time) on the London business day following the date of the relevant transaction. This requirement will continue until the date on which the Acquisition and/or Scheme becomes effective, 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 Avacta or Curidium, 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 Avacta or of Curidium by Avacta or Curidium, or by any of their respective "associates", must be disclosed by no later than 12.00 noon (London 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. In particular, a person will be treated as having an "interest" by virtue of the ownership or control of securities, or by virtue of any option in respect of, or derivative referenced to, securities. Terms in quotation marks are defined in the City Code, which can also be found on the Panel's website. If you are in any doubt as to whether or not you are required to disclose a dealing under Rule 8, you should consult the Panel. 20. General Avacta reserves the right, with the consent of the Panel, to elect to implement the Recommended Offer by making a takeover offer for the entire issued and to be issued share capital of Curidium. If Avacta elects to implement the Recommended Offer by a takeover offer, that offer will be implemented on the same terms (subject to appropriate amendments), so far as applicable, as those which would apply to the Scheme, except that the Acquisition may exclude Curidium Shareholders resident in certain overseas jurisdictions. Further, if sufficient acceptances of any such offer are received and/or sufficient Curidium Shares are otherwise acquired, it is the intention of Avacta to acquire compulsorily any outstanding Curidium Shares to which such offer relates. This announcement is not intended to and does not constitute or form part of, an offer or invitation to sell or subscribe for or acquire or exchange securities in Avacta or Curidium or a solicitation of any vote or approval in any jurisdiction pursuant to the Recommended Offer or otherwise. The full terms and conditions of the Scheme will be set out in the Scheme Document. Curidium Shareholders are advised to read carefully the formal documentation in relation to the Recommended Offer, once it is dispatched. In deciding whether or not to approve the Scheme, Curidium Shareholders must rely solely on the terms and conditions of the Recommended Offer and the information contained, and the procedures described, in the Scheme Document. The distribution of this announcement in jurisdictions other than the UK and the implications of the Scheme for Curidium Shareholders outside the UK may be affected by the laws of the relevant jurisdictions. Curidium Shareholders outside the UK should inform themselves about and observe any applicable requirements. It is the responsibility of each Curidium Shareholder to satisfy himself as to the full observance of the laws of the relevant jurisdiction in connection therewith, including the obtaining of any governmental, exchange control or other consents which may be required to be observed and the payment of any issue, transfer or other taxes in such jurisdictions. This announcement has been prepared for the purpose of complying with English law and the City Code and the information disclosed may not be the same as that which would have been disclosed if this announcement had been prepared in accordance with the laws of jurisdictions outside the UK. Novum Securities, which is authorised and regulated in the UK by the Financial Services Authority, is acting as financial adviser to Avacta in connection with the Recommended Offer and no-one else and will not be responsible to anyone other than Avacta for providing the protections afforded to clients of Novum Securities nor for providing advice in relation to the Recommended Offer nor any other matter referred to in this announcement. FinnCap, which is authorised and regulated in the UK by the Financial Services Authority, is acting as financial adviser and broker to Curidium in connection with the Recommended Offer and no-one else and will not be responsible to anyone other than Curidium for providing the protections afforded to clients of FinnCap nor for providing advice in relation to the Recommended Offer nor any other matter referred to in this announcement. 21. Appendices Appendix I sets out the Conditions for implementation of the Recommended Offer and the Scheme. Appendix II sets out the bases and sources of information from which the financial calculations used in this announcement have been derived. Appendix III contains particulars of the irrevocable undertakings referred to in paragraph 11 of this announcement.
