FOR IMMEDIATE RELEASE 13 August 2004 RECOMMENDED OFFER by UBS INVESTMENT BANK on behalf of MICROGEN PLC for the ordinary share capital AFA SYSTEMS PLC AND PLACING OF 4,300,000 NEW ORDINARY SHARES 1 Introduction The Boards of Microgen and AFA Systems announce the terms of a recommended offer for the whole of the issued and to be issued ordinary share capital of AFA Systems and a placing of 4,300,000 Microgen Shares at 57.0 pence per share. The Offer will be made by UBS Investment Bank on behalf of Microgen. 2 The Offer and the Loan Note Acquisition Agreement The Offer will be made on the following basis: for each AFA Systems Share 4.51 pence in cash and 0.18168 Consideration Shares The Offer values each AFA Systems Share at 15.32 pence, based on the average Closing Price of 59.5 pence per Microgen Share over the five business days prior to the date of this Announcement, and values the whole of AFA Systems' existing issued share capital at approximately Â£7.2 million. The Offer represents a premium of approximately 2.1 per cent. to the average Closing Price per AFA Systems Share over the five business days prior to this Announcement. Based on the Closing Price of 59.5 pence per Microgen Share on 12 August 2004 (the last dealing day prior to the date of this Announcement), the Offer values each AFA Systems Share at approximately 15.32 pence. In view of AFA Systems' size in relation to Microgen, the Acquisition is conditional, inter alia, on the approval of Microgen's shareholders which is to be sought at an EGM. AFA Systems has in place the Â£1.5 million Loan Notes and the Â£250,000 Loan Notes. The Â£1.5 million Loan Notes convert into AFA Systems Shares once an offer for AFA Systems is declared wholly unconditional. Microgen and AFA Systems have reached agreement with the Loan Notes Holder that, subject to the Offer becoming or being declared wholly unconditional, Microgen will acquire the Â£1.5 million Loan Notes from the Loan Notes Holder for Â£1.5 million, to be satisfied by Â£441,580 in cash and Â£1,058,420 by the issue of 1,778,857 Consideration Shares. The Â£250,000 Loan Notes are redeemable for cash on the Offer becoming or being declared wholly unconditional. A circular to Shareholders including notice of EGM, the Offer Document to AFA Systems Shareholders and Listing Particulars of Microgen containing further information about the Acquisition and AFA Systems will be posted shortly. AFA Systems Shareholders who validly accept the Offer may elect in respect of some or all of their AFA Systems Shares, under the Mix and Match Election, to receive as consideration either: (i) all Consideration Shares and no cash, on the basis of 0.25748 Consideration Shares for each AFA Systems Share in respect of which an election is made; or (ii) all cash and no Consideration Shares, on the basis of 15.32 pence in cash for each AFA Systems Share in respect of which an election is made; instead of the combination of Consideration Shares and cash provided under the basic terms of the Offer. However, whilst it is possible for the Offer to be satisfied entirely in Microgen Shares, the total amount of consideration satisfied in cash will not exceed at any time Â£2.16 million. The Offer will be conditional on, amongst other things, the approval of Microgen's shareholders and will be subject to the conditions and the further terms set out in Appendix I and those to be set out in the Offer Document and the Form of Acceptance. 3 The Placing The Placing Shares represent approximately five per cent. of Microgen's issued share capital prior to the Placing, the Acquisition and the completion of the Loan Note Acquisition Agreement, and are to be placed with institutional investors at a price of 57 pence per share. The net proceeds of the Placing (approximately Â£2.43 million) received by Microgen will be retained by the Microgen Group for ongoing corporate purposes. The total number of New Microgen Shares that will be issued as a result of the Placing, upon completion of the Loan Note Acquisition Agreement (assuming the Offer becomes or is declared wholly unconditional) and completion of the Acquisition, under the basic terms of the Offer, will be 14,650,982. The maximum amount of New Microgen Shares that could be issued under the Placing, Acquisition and Loan Note Acquisition Agreement is 18,227,419. Applications will be made to the UK Listing Authority for the Placing Shares and the Consideration Shares to be admitted to the Official List and to the London Stock Exchange for admission to trading on its market for listed securities. The Placing is conditional, inter alia, on Admission of the Placing Shares but it is not conditional on the Offer becoming or being declared wholly unconditional or on the acquisition of the Â£1.5 million Loan Notes. 4 Recommendation The AFA Systems Board, which has been so advised by Bridgewell, considers the terms of the Offer to be fair and reasonable. In providing advice to the AFA Systems Board, Bridgewell has taken into account the commercial assessments of the AFA Systems Directors. Accordingly, the AFA Systems Directors unanimously recommend AFA Systems Shareholders to accept the Offer. 5 Support of AFA Systems Shareholders and Microgen Shareholders Microgen has received irrevocable undertakings to accept the Offer in respect of a total of 15,678,940 AFA Systems Shares representing approximately 33.23 per cent. of the existing issued AFA Systems Shares, as detailed below. Irrevocable undertakings to accept (or use all reasonable endeavours to procure the acceptance of) the Offer have been received from the AFA Systems Directors in respect of beneficial holdings of 3,414,002 AFA Systems Shares representing approximately 7.24 per cent. of the existing issued AFA Systems Shares. These irrevocable undertakings are binding even in the event of a higher competing offer but will cease to be binding if the Offer lapses or is withdrawn. Microgen has also received irrevocable undertakings to accept (or use all reasonable endeavours to procure the acceptance of) the Offer from certain institutional and other shareholders in respect of 12,264,938 AFA Systems Shares representing approximately 25.99 per cent. of the issued share capital of AFA Systems. These irrevocable undertakings are binding even in the event of a higher competing offer but will cease to be binding if the Offer lapses or is withdrawn. In addition to the irrevocable undertakings, Microgen has received non-binding letters of intent to accept the Offer from certain institutional shareholders in respect of a total of 7,052,752 AFA Systems Shares representing approximately 14.95 per cent. of the existing issued AFA Systems Shares. In aggregate, therefore, Microgen has received irrevocable undertakings and non-binding letters of intent to accept the Offer in respect of 22,731,692 AFA Systems Shares, representing approximately 48.18 per cent. of the existing issued AFA Systems Shares. The Microgen Board will vote in favour of the resolutions relating to the Offer, details of which are in paragraph 16 below and which are to be proposed at Microgen's EGM, in respect of their own beneficial holdings of 9,674,066 Microgen Shares, representing approximately 11.12 per cent. of the existing issued share capital of Microgen. 6 Finance Full acceptance of the Offer and completion of the Loan Note Acquisition Agreement would require a maximum cash payment of approximately Â£2.60 million by Microgen, which will be funded out of Microgen's existing cash resources. UBS is satisfied that sufficient financial resources are available for Microgen to satisfy the consideration payable as a result of full acceptance of the Offer and completion of the Loan Note Acquisition Agreement even if the Placing does not go ahead. 7 Loan Notes As part of the consideration payable on the acquisition of Strategic Asset Management Solutions Limited ('SAMS'), AFA Systems issued to the Loan Notes Holder the Â£250,000 Loan Notes and the Â£1.5 million Loan Notes. The Â£250,000 Loan Notes will be repayable in cash upon the Offer becoming or being declared wholly unconditional. It has, however, come to the AFA Systems Board's attention that the announcement by AFA Systems and the circular sent to AFA Systems Shareholders ('the AFA Systems Documents') both dated 7 November 2003 did not contain a complete summary of the change of control provisions of the Â£1.5 million Loan Notes because the second part of the applicable formula for conversion was omitted. The AFA Systems Documents stated that in the event of a change of control of AFA Systems, all outstanding unredeemed and unconverted Â£1.5 million Loan Notes will be converted into AFA Systems Shares at a conversion rate of one AFA Systems Share for every Â£0.36 nominal amount of the notes being converted ('the Conversion Rate'). The conditions of the Â£1.5 million Loan Notes in fact provide that upon a change of control of AFA Systems, all unredeemed Â£1.5 million Loan Notes then in issue shall be automatically converted into AFA Systems Shares at whichever of the following rates would yield the higher number of AFA Systems Shares: (i) the Conversion Rate; and (ii) at a price per AFA Systems Share equal to the average of the mid market valuations of AFA Systems Shares as quoted by the London Stock Exchange plc over the 10 business days immediately preceding the date on which either a controlling interest (being the ability to exercise or control the exercise of in the aggregate more than 50 per cent of the total voting rights (within the meaning of section 736A(2) of the Act) capable of being exercised at general meetings of AFA Systems) in AFA Systems, or the date on which the Offer is declared wholly unconditional (whichever is the earlier). The conditions of the Â£1.5 million Loan Notes were varied pursuant to the Loan Note Variation such that for the purposes of the Offer only the Â£1.5 million Loan Notes (i) become transferable (whereas prior to the variation they were not transferable); and (ii) do not convert to AFA Systems Shares automatically upon a change of control of AFA Systems. Microgen has entered into the Loan Note Acquisition Agreement by which Microgen agrees to purchase the Â£1.5 million Loan Note from the Loan Notes Holder. The Loan Note Acquisition Agreement is conditional upon the Offer becoming or being declared unconditional in all respects and provides that upon the Offer becoming or being declared unconditional Microgen shall pay to the Loan Note Holder Â£1.5 million consisting of Â£441,580 in cash and Â£1,058,420 satisfied by the issue of 1,778,857 Microgen Shares. The Â£1.5 million Loan Note will then be held by Microgen who shall have the right (but not the obligation) to convert the Â£1.5 million Loan Note into AFA Systems Shares. Further information on the Â£250,000 Loan Notes and the Â£1.5 million Loan Notes will be included in the Offer Document which it is intended will be issued shortly. 8 Background to and reasons for the Offer Background The Microgen Board believes that the small-cap software and IT services sector in the UK is fragmented and that selective consolidation is likely to serve the interests of small companies and their shareholders by creating larger, better capitalised companies with complementary products and service offerings and by eliminating duplicated management and infrastructure costs. The Microgen Board wishes Microgen to be an active participant in such consolidation and believes that the acquisition of AFA Systems will strengthen Microgen's position as an IT services and solutions provider in the UK Market. AFA Systems reported operating losses of Â£1.2 million in the six months to 30 June 2004 after charging group costs of Â£0.6 million. Specific opportunities to reduce the cost base have been identified by Microgen including: o The elimination of duplicated PLC and group costs o The elimination of excess property facilities o The consolidation of business operations o The migration of the SAMS development activities to South Africa, an action already initiated by the AFA Systems Board. In addition, Microgen has identified further cost savings which may be derived from the consolidation of the two businesses which have not yet been fully quantified. As at 31 December 2003, the AFA Systems Group had accumulated tax losses of in excess of Â£12 million, subject to final agreement of the 2003 tax computations with the Inland Revenue. Microgen will seek to utilise these losses over future years, however, there is no guarantee that these losses will be capable of being utilised. Benefits of the Acquisition for Microgen The Microgen Board believes that the acquisition of AFA Systems strengthens Microgen's presence and offering in the financial services market, increasing the scale of the Group's vertical sector business and significantly expanding the Group's customer base. Prospects for the Enlarged Group The Directors believe that the Acquisition will strengthen Microgen's position as an IT services and solutions provider in the financial services market. The Enlarged Group is expected to benefit from having an increased presence and expanded client base, with a broader range of software and service offerings with which to develop cross-selling opportunities. Historically, Microgen has adopted a rigorous approach to cost control. This same management discipline will be brought to the Enlarged Group, enabling rationalisation of duplicated infrastructure costs. The benefits of the Acquisition are likely to be reflected in the Enlarged Group's financial year ending 31 December 2005 and subsequent periods, with the costs of rationalisation of approximately Â£2 million being reported in the second half of 2004. If the Offer is accepted by AFA Systems Shareholders, the Acquisition will provide greater scale and new opportunities for the Microgen Group. Furthermore, the increased size of the Enlarged Group will enable the Microgen Board to explore further strategic opportunities in the IT sector. Any statement or inference that the Acquisition is expected to be earnings enhancing for the Enlarged Group should not be interpreted to mean that the earnings per share in the financial year following the Acquisition, or in any subsequent period, will necessarily be greater than those for the relevant preceding financial period. 9 Details of the Placing and application of proceeds Pursuant to the Placing, which has been arranged by UBS on behalf of Microgen, the Placing Shares are being conditionally placed with institutional and other investors at the Placing Price. The Placing will raise approximately Â£2.45 million before expenses (approximately Â£2.43 million net of expenses) for Microgen. The Placing Shares represent approximately five per cent. of the existing issued share capital of Microgen prior to the Placing, the Acquisition and completion of the Loan Note Acquisition Agreement. The Placing Shares will be issued credited as fully paid and will rank pari passu with the existing Microgen Shares, including the right to receive all dividends and other distributions declared, made or paid after these are issued. Microgen has applied for Admission of the Placing Shares and it is expected that Admission of the Placing Shares will take place and that trading will commence in the Placing Shares on 18 August 2004. The Placing is conditional, inter alia, on: (a) the Placing Agreement becoming unconditional and not having been terminated in accordance with its terms prior to Admission of the Placing Shares; and (b) Admission of the Placing Shares becoming effective no later than 18 August 2004. After payment of the expenses of the Placing, the net proceeds of the Placing (approximately Â£2.43 million) received by Microgen will be retained by the Microgen Group for ongoing corporate purposes. In the event that the Placing is not successful, Microgen has sufficient existing resources to complete the Acquisition and the acquisition of the Â£1.5 million Loan Note. The Placing is not conditional upon the Acquisition and if the Acquisition is not completed, the net proceeds from the Placing will be first applied in satisfying costs incurred by the Microgen Group in relation to the Acquisition. The remaining funds will be placed on deposit and retained to finance the further development of the Microgen Group. If a suitable opportunity arose, the proceeds would also be available to fund other acquisitions in line with the Microgen Group's publicly stated strategy. 10 Information on Microgen In terms of both operating results and the strategic development of the Microgen Group, the 2003 financial year was one of considerable success. Despite the difficult market environment, the Board of Microgen reported a strong performance for the year ended 31 December 2003 for its continuing businesses, due largely to the disciplined management approach maintained during the period. The two acquisitions of M.M.T. Computing plc and Imago QA Limited, completed towards the end of the 2003 financial year substantially increased the size of the Microgen Group, providing an expanded customer base and broader product and service offerings. In both acquisitions, the integration has been rapid and effective to reduce the cost base and realize the benefits from the increased scale. The benefits derived from the acquisition and integration of these businesses is affirmed in the Microgen unaudited results for the first six months which were released on 15 July 2004. Microgen businesses The business activities of Microgen include: Consultancy. The Microgen Group's consultancy services currently contribute the greatest proportion of revenue to Microgen. These activities include IT consultancy services such as information management, integration and software testing & acceptance, but also include more business-specific consultancy services associated with IT, particularly in the financial services sector where the deployment of Microgen's software applications typically require both technical and domain expertise. Managed services. Microgen provides added-value transactional services in billing, payment and hosted database and document management, where Microgen adds value by processing, distributing, storing and analysing data for a wide variety of applications, including the Microgen Group's billing and document management services. Microgen also provides application support services for the ongoing support of developments made by the consultancy operations and/or third party software/consultancy projects. Software. Microgen has a number of software offerings, including: â€¢ Microgen-OST Business Rules is a rules-driven integration tool, which also provides a core technology for additional products such as Reconciliation software and Microgen's Financial Data Repository. This technology is also being used in the development of new products, such as the replacement for the Cortex Derivatives system. â€¢ Microgen is a leading provider of BACS payment software and solutions in the UK. With the launch of BACS-IP, all UK customers using BACS payment transfers will need to upgrade their software over the next two years and Microgen has developed a completely new range of products to maximise the potential from this opportunity. â€¢ Microgen also provides systems for the management of customer acquisition and processing for suppliers of utility services in deregulated energy markets.

As at 30 June 2004, AFA Systems had cash (and cash equivalents) of approximately Â£0.7 million as stated in AFA Systems' unaudited interim financial statements. 12 Current trading and prospects of AFA Systems AFA Systems' first half performance was disappointing given that further losses were incurred and underlying sales excluding SAMS were down. The anticipated recovery in the market has to date not been reflected in new sales. The AFA Systems Board remains confident in the level of business from existing customers. 13 Directors, management and employees Microgen intends to safeguard the existing employment rights, including pension rights, of the management and employees of AFA Systems. AFA Systems' employees will be given the opportunity to transfer onto Microgen's standard terms and conditions in the event that the Offer becomes or is declared wholly unconditional. Mike Hart (the Chairman and Chief Executive of AFA Systems) will remain on the board of AFA Systems as a non-executive director to assist in the integration of the two companies upon the Offer becoming or being declared wholly unconditional. The other directors of AFA Systems have agreed to resign upon the Offer becoming or being declared wholly unconditional. 14 AFA Systems Share Option Schemes The Offer will extend to any further AFA Systems Shares unconditionally allotted or issued on or prior to the time and date on which the Offer closes (or by such earlier time and date as Microgen may, subject to the City Code or with the consent of the Panel, determine) as a result of the exercise of options granted under any of the AFA Systems Share Option Schemes or otherwise. As the Offer Price is below the exercise price of all existing AFA Systems Options, Microgen will not make any proposals to holders of AFA Systems Options in the event that the Offer becomes or is declared wholly unconditional. A separate resolution is being proposed at Microgen's EGM in respect of options to be granted to key AFA Systems Employees who transfer onto the standard Microgen employment terms and conditions. 15 Inducement Fee Microgen has entered into an inducement fee letter agreement with AFA Systems dated 13 August 2004. In that letter agreement, AFA Systems has agreed to pay Microgen a fee of Â£72,293 in the event that the AFA Systems Board withdraws or adversely qualifies its recommendation of the Offer prior to the Offer becoming wholly unconditional as to acceptances, lapsing or being withdrawn in accordance with its terms, or if a competing third party offer is announced which subsequently becomes wholly unconditional. Also in a separate compensation fee letter agreement, Microgen has agreed to pay AFA Systems a fee of Â£72,293 in the event that Shareholders do not give the necessary approvals for the Offer to proceed at the EGM or Microgen Directors change their recommendation of the Acquisition to Microgen Shareholders. In both cases, the fee to be paid is in respect of the time, costs and expense of the parties in performing due diligence and negotiating the terms of the Offer. 16 Shareholders' approval In view of the relative sizes of the two companies, the Offer is conditional, inter alia, upon the approval of Microgen Shareholders at an EGM to be convened at 11 Park Street, Windsor, Berkshire SL4 1LU. Resolutions will be proposed in order to approve and effect the Offer. Accordingly, a circular convening an EGM will be posted to Shareholders as soon as possible. The Microgen Board will vote in favour of the resolutions relating to the Offer to be proposed at the EGM in respect of their own beneficial holdings of 9,674,066 Microgen Shares representing approximately 11.12 per cent. of the existing issued share capital of Microgen. 17 Compulsory acquisition and cancellation of listing of AFA Systems Shares Following the Offer becoming or being declared unconditional in all respects Microgen intends to use the procedures set out in sections 428 to 430F of the Act to acquire compulsorily any outstanding AFA Systems Shares to which the Offer relates. Microgen will also procure the making of an application by AFA Systems to the Alternative Investment Market of the London Stock Exchange for the cancellation of the listing of AFA Systems Shares on the Alternative Investment Market and to the London Stock Exchange for the cancellation of the admission to trading of AFA Systems Shares. An announcement will be made following either (i) the Offer becoming or being declared unconditional in all respects or (ii) the commencement of the compulsory acquisition procedures under sections 428 to 430F of the Act in respect of the AFA Systems Shares, stating the anticipated time and date when the listing and admission to trading will be cancelled being not less than 20 business days following such event. The cancellation of the listing of AFA Systems Shares will significantly reduce the liquidity and marketability of any AFA Systems Shares not assented to the Offer and their value may be affected as a consequence. 18 Overseas Shareholders The availability of the Offer to persons not resident in the United Kingdom may be affected by the laws of their relevant jurisdictions. Any persons who are subject to the laws of any jurisdiction other than those of the United Kingdom should inform themselves about and observe any applicable legal and regulatory requirements in their jurisdiction. It is the responsibility of any Overseas Shareholder wishing to accept the Offer to satisfy themselves as to the full observance of the laws and regulatory requirements of the relevant territory in connection therewith, including the obtaining of any governmental, exchange control or other consents which may be required or the compliance with other necessary formalities needing to be observed and the payment of any issue, transfer or other taxes or duties due in such jurisdiction.

The New Microgen Shares to be issued pursuant to the Offer have not been and will not be registered under the United States Securities Act of 1933 (as amended) or under the securities laws of any jurisdiction of the United States, nor has a prospectus in relation to the New Microgen Shares been lodged with, or registered by, the Securities Commission of any province or territory of Canada or the Australian Securities and Investments Commission or the Ministry of Japan.

These statements typically contain words such as 'intends', 'expects', 'anticipates', 'estimates' and words of similar import. By their nature, forward-looking statements involve risk and uncertainty because they relate to events and depend on circumstances that will occur in the future. There are a number of factors that could cause actual results and developments to differ materially from those expressed or implied by such forward-looking statements. These factors include, but are not limited to, factors identified elsewhere in this Announcement as well as the following possibilities: future revenues are lower than expected; costs of difficulties relating to the integration of the businesses of Microgen and AFA Systems, or of other future acquisitions, are greater than expected; expected cost savings from the transaction or from other future acquisitions are not fully realised or realised within the expected time frame; competitive pressures in the industry increase; general economic conditions or conditions affecting the relevant industries, whether internationally or in the places where Microgen and AFA Systems do business, are less favourable than expected; and/or conditions in the securities market are less favourable than expected. UBS is acting exclusively for Microgen in connection with the Acquisition and the Placing and no one else and will not be responsible to anyone other than Microgen for providing the protections afforded to clients of UBS, or for providing advice in relation to the Acquisition or the Placing. Bridgewell, which is regulated in the United Kingdom by the Financial Services Authority, is acting for AFA Systems and no one else and will not be responsible to anyone other than Microgen for providing the protection afforded to clients of Bridgewell, or for providing advice in relation to the Acquisition.

Application for listing and admission to trading Application will be made to the UK Listing Authority (the 'UK Listing Authority ') for admission of the Placing Shares to the Official List of the UK Listing Authority (the 'Official List') and to the London Stock Exchange for admission to trading of the Placing Shares on the London Stock Exchange's market for listed securities (together 'Admission'). It is expected that Admission of the Placing Shares will take place at 8.00 a.m. on 18 August 2004 (the 'Commencement of Trading'). Principal terms of the Placing 1. UBS is arranging the Placing as an agent of Microgen. 2. Participation will only be available to persons invited to participate by UBS. UBS is entitled to enter bids as principal in the Placing. UBS will determine in its absolute discretion the extent of each Placee's participation in the Placing which will not necessarily be the same for each Placee. 3. The price payable per Placing Share shall be the Placing Price. 4. Participation in the Placing will be made on the terms and conditions in this Appendix and upon acceptance by UBS, will be legally binding on the Placee by whom, or on behalf of whom it is made and will not be capable of variation or revocation. 5. A Placee's allocation will be agreed with and confirmed with it orally by UBS, and a conditional contract note will be dispatched as soon as possible thereafter. UBS's oral confirmation to such Placee will constitute a legally binding commitment upon such Placee to acquire the number of Placing Shares allocated to it at the Placing Price on the terms and conditions set out in this Appendix and in accordance with Microgen's Memorandum and Articles of Association. 6. Each Placee's obligations will be owed to Microgen and to UBS. 7. The Placing Shares will be offered and sold outside of the United States in accordance with the terms of Regulation S under the Securities Act. 8. All obligations under the Placing will be subject to fulfilment of the conditions referred to below under 'Conditions of the Placing'. Conditions of the Placing The Placing is conditional upon the Placing Agreement becoming unconditional and not having been terminated in accordance with its terms. UBS's obligations to Microgen in respect of the Placing are conditional on, inter-alia: 1. Commencement of Trading by no later than 8.00 a.m. on 18 August 2004; 2. none of the representations, warranties or undertakings given by Microgen in the Placing Agreement having been breached; and 3. Microgen not being in breach of any of its obligations under the Placing Agreement. If the conditions above are not satisfied or waived by UBS within the stated time period (or such later time and/or date UBS may agree) the Placing will lapse. UBS may, at its discretion and upon such terms as it thinks fit, waive compliance by Microgen with the whole or any part of any of Microgen's obligations in relation to the conditions in the Placing Agreement. UBS reserves the right to waive or to extend the time and/or date for fulfillment of any of the conditions in the Placing Agreement. Any such extension or waiver will not affect Placees' commitments as set out in this Announcement. Neither UBS or Microgen shall have any liability to any Placee (or to any other person whether acting on behalf of a Placee or otherwise) in respect of any decision it may make as to whether or not to waive or to extend the time and/or date for the satisfaction of any condition to the Placing nor for any decision they may make as to the satisfaction of any condition. By participating in the Placing each Placee agrees with UBS that the exercise by Microgen or UBS of any right or other discretion under the Placing Agreement shall be within the absolute discretion of Microgen or UBS (as the case may be) and that neither Microgen or UBS need make any reference to such Placee and that neither Microgen or UBS shall have any liability to such Placee (or to any other person whether acting on behalf of a Placee or otherwise) whatsoever in connection with any such exercise. By participating in the Placing each Placee agrees that its rights and obligations terminate only in the circumstances described above and will not be capable of rescission or termination by it. Right to terminate under the Placing Agreement UBS may, by notice to Microgen, terminate the Placing Agreement at any time before Admission of the Placing Shares becoming effective in certain circumstances. These include inter alia: 1. any statement contained in this Announcement has become or been discovered to become untrue, incorrect or misleading; 2. any breach of any of the representations or warranties given by Microgen in the Placing Agreement or of any obligation of Microgen under the Placing Agreement; 3. any event occurring or matter arising at any time up to Admission of the Placing Shares which would have rendered any of the representations and warranties given by Microgen in the Placing Agreement untrue, inaccurate or misleading in any respect; and 4. any material adverse change in the financial markets in the United Kingdom, the United States or in the international financial markets, any outbreak of hostilities or escalation thereof or other calamity or crisis or any change or development involving a prospective change in national or international financial, political or economic conditions or currency exchange rates or exchange controls in each case as would, in the opinion of UBS make it impractical or inadvisable to market the Placing Shares or to enforce contracts for the sale of the Placing Shares. If UBS's obligations under the Placing Agreement are terminated in accordance with its terms the rights and obligations of each Placee in respect of the Placing as described in this Announcement (including this Appendix) shall cease and determine at such time and no claim can be made by any Placee in respect thereof. No Prospectus No offering document or prospectus has been or will be submitted to be approved by the UK Listing Authority or filed with the Registrar of Companies in England and Wales in relation to the Placing or the Placing Shares and Placees' commitments will be made solely on the basis of the information contained in this Announcement (including this Appendix). Each Placee, by accepting a participation in the Placing, agrees that the content of this Announcement (including this Appendix) is exclusively the responsibility of Microgen and confirms that it has neither received nor relied on any other information, representation, warranty or statement made by or on behalf of UBS or Microgen and neither UBS or Microgen will be liable for any Placee's decision to accept this invitation to participate in the Placing based on any other information, representation, warranty or statement. Each Placee acknowledges, agrees and warrants that it has relied on its own investigation of the business, financial or other position of Microgen in deciding to participate in the Placing. Nothing in this paragraph shall exclude the liability of any person for fraudulent misrepresentation. Registration and Settlement Settlement of transactions in the Placing Shares following Admission of the Placing Shares will take place within the CREST system, subject to certain exceptions. UBS and Microgen reserve the right to require settlement for and delivery of the Placing Shares to Placees by such other means that it deems necessary if delivery or settlement is not possible or practicable within the CREST system within the timetable set out in this Announcement or would not be consistent with the regulatory requirements in the Placee's jurisdiction. Each Placee allocated Placing Shares in the Placing will be sent a conditional contract note stating the number of Placing Shares allocated to it, the Placing Price and the aggregate amount owed by such Placee. In accepting the allocation of Placing Shares set out in the conditional contract note, such Placee agrees that it will do all things necessary to ensure that delivery and payment is completed in accordance with either the standing CREST or certificated settlement instructions which it has in place with UBS. Settlement will be on a T+3 basis unless otherwise notified by UBS. Interest is chargeable daily on payments not received from Placees on the due date in accordance with the arrangements set out above at the rate of 5 percentage points above prevailing LIBOR. Each Placee is deemed to agree that if it does not comply with these obligations, UBS may sell its Placing Shares on such Placees behalf and retain from the proceeds, for Microgen's account and benefit, an amount equal to the Placing Price plus any interest due. The relevant Placee will, however, remain liable for any shortfall below the Placing Price and may be required to bear any stamp duty or stamp duty reserve tax (together with any interest or penalties) which may arise upon the sale of such Placing Shares on such Placee's behalf. If Placing Shares are to be delivered to a custodian or settlement agent, Placees should ensure that the conditional contract note is copied and delivered immediately to the relevant person within that organisation. Insofar as Placing Shares are registered in a Placee's name or that of its nominee or in the name of any person for whom a Placee is contracting as agent or that of a nominee for such person, such Placing Shares should, subject as provided below, be so registered free from any liability to UK stamp duty or stamp duty reserve tax.

Neither UBS or Microgen will be responsible for any liability to stamp duty or stamp duty reserve tax resulting from a failure to observe this requirement. Each Placee and any person acting on behalf of such Placee agrees to participate in the Placing and it agrees to indemnify Microgen and UBS in respect of the same on the basis that the Placing Shares will be allotted to the CREST stock account of UBS who will hold them as nominee on behalf of such Placee until settlement in accordance with its standing settlement instructions; 22. acknowledges that any agreements entered into by it pursuant to these terms and conditions shall be governed by and construed in accordance with the laws of England and it submits (on behalf of itself and on behalf of any Placee on whose behalf it is acting) to the 'exclusive' jurisdiction of the English courts as regards any claim, dispute or matter arising out of any such contract, except that enforcement proceedings in respect of the obligation to make payment for the Placing Shares (together with any interest chargeable thereon) may be taken by Microgen or UBS in any jurisdiction in which the relevant Placee is incorporated or in which any of its securities have a quotation on a recognised stock exchange; 23. acknowledges that UBS may (at its absolute discretion) satisfy its obligations to procure Placees by itself agreeing to become a Placee in respect of some or all of the Placing Shares or by nominating any connected or associated person to do so; and 24. agrees that Microgen, UBS and others will rely upon the truth and accuracy of the foregoing representations, warranties, acknowledgements and undertakings. The agreement to settle a Placee's acquisition (and/or the acquisition of a person for whom such Placee is contracting as agent) free of stamp duty and stamp duty reserve tax depends on the settlement relating only to an acquisition by it and/or such person direct from Microgen for the Placing Shares in question. Such agreement assumes that the Placing Shares are not being acquired in connection with arrangements to issue depositary receipts or to transfer the Placing Shares into a clearance service. If there are any such arrangements, or the settlement related to any other dealing in the Placing Shares, stamp duty or stamp duty reserve tax may be payable, for which neither Microgen or UBS will be responsible. If this is the case, each Placee should seek its own advice and notify UBS accordingly. When a Placee or person acting on behalf of the Placee is dealing with UBS, any money held in an account with UBS on behalf of the Placee and/or any person acting on behalf of the Placee will not be treated as client money (within the meaning of the rules and regulations of the Financial Services Authority made under FSMA) which, therefore, will not require UBS to segregate such money, as that money will be held by it under a banking relationship and not as a trustee. Past performance is no guide to future performance and persons needing advice should consult an independent financial adviser. All times and dates in this Announcement may be subject to amendment. UBS shall notify the Placees and any person acting on behalf of the Placees of any changes.
