Dear Shareholder

ANNUAL GENERAL MEETING

Set out in this letter, on pages 4 to 6, is a formal notice of the Annual General Meeting of Microgen plc to be held on Monday 18 May 2015 at 9.00 am at Old Change House, 128 Queen Victoria Street, London, EC4V 4BJ. The purpose of this letter is for the Board to explain to you the resolutions numbered 4 and 5 which are proposed in the notice of Annual General Meeting as ordinary business, as well as explaining resolutions 8 to 11 which are proposed in such notice as special business.

Re-election of Directors (Resolutions 4 and 5)

The Articles of Association of the Company require that certain Directors shall retire by rotation at annual general meetings of the Company and stand for re-election. As indicated in the Company's 2014 Annual Report, Philip Wood and Peter Bertram are retiring by rotation this year. If re-elected, Peter Bertram intends to retire from the Board at the Annual General Meeting to be held in 2016 as he shall have completed nine years' service as a non-executive director.

The Board recommends the re-appointment of Mr Philip Wood, who was appointed Group Finance Director on 2 January 2007. The Board considers that Mr Wood, a Chartered Accountant, continues to make an effective contribution to the Board and recommends his re-appointment at the Annual General Meeting. The Board has asked Mr Wood to continue in office and accordingly the Board recommends his re-appointment at the forthcoming Annual General Meeting under Resolution 4.

The Board also recommends the re-appointment of Mr Peter Bertram who was first appointed as a non-executive director on 3 October 2006 and then Chairman of the Audit Committee on 1 May 2007. On 19 April 2011, Mr Bertram was appointed as the senior independent non-executive director of the Company. Mr Bertram is a Fellow of the Institute of Chartered Accountants in England and Wales and is also Chairman of Phoenix IT Group plc and Ten Alps plc. The Board believes that Mr Bertram continues to be an effective and independent member of the Board and demonstrates commitment to his role as a non-executive director and in his capacity as senior independent non-executive director and as Chairman of the Audit Committee. The Board recommends his re-appointment at the forthcoming Annual General Meeting under Resolution 5.

Allotment of Securities (Resolution 8)

The Association of British Insurers ('ABI') guidelines state that ABI members will permit, and treat as routine, a request for authorisation to allot up to one-third of the existing issued share capital of the Company, together with the number of shares required to be allotted in respect of share incentive schemes.

Accordingly, under Resolution 8, the Directors are seeking authority to allot ordinary shares and other equity securities up to an aggregate nominal amount of £1,243,511 without the prior consent of Shareholders in order to replace the authority given at the general meeting of the Company held on 18 March 2015 ("General Meeting"). This is equivalent to one-third of the issued ordinary share capital of the Company as at 2 April 2015.

---

The Company has no present intention of allotting new shares (other than in connection with the Company's share incentive schemes). The Directors consider it desirable to have sufficient authority in place, as permitted by corporate governance guidelines, to respond to market developments and to enable allotments to take place in a timely manner, should such a situation arise.

The authority sought in Resolution 8 will be proposed as an ordinary resolution and will expire at the conclusion of the next Annual General Meeting in 2016 or on 31 May 2016, whichever is the earlier.

Disapplication of Pre-Emption Rights (Resolution 9)

A special resolution is proposed to grant the Directors a new authority to allot equity securities for cash without first being required to offer such securities to existing Shareholders in proportion to their existing shareholdings, other than by way of a rights issue or in connection with a pre-emptive offer, up to an aggregate nominal amount of £186,527, being equal to 5 per cent. of the issued ordinary share capital of the Company as at 2 April 2015 and amounting to 2,901,526 ordinary shares. This Resolution complies with the ABI and Pre-emption Group guidelines.

In line with the Pre-emption Group's Statement of Principles, the Directors do not intend to allot shares for cash on a non pre-emptive basis (other than pursuant to a rights issue or pre-emptive offer) in excess of an amount equal to 7.5 per cent. of the total issued ordinary share capital of the Company within a rolling three-year period without prior consultation with Shareholders. The authority sought in Resolution 9 is to replace the authority given at the General Meeting and will expire at the conclusion of the next Annual General Meeting in 2016 or on 31 May 2016, whichever is the earlier.

Purchase of Own Shares (Resolution 10)

It is proposed that the existing authority to enable the Company to make purchases of its own shares should be renewed until the next Annual General Meeting in 2016. The special resolution proposed would enable the Company to make purchases on the London Stock Exchange limited to 5,803,052 shares (equivalent to 10 per cent. of its issued share capital as at 2 April 2015), at, or between, the minimum and maximum prices specified in Resolution 10. Any shares purchased by the Company pursuant to this Resolution may be immediately cancelled or held in treasury. Under the Companies Act 2006, the Company is allowed to hold its own shares in treasury following a buy-back, instead of cancelling them. Such shares may be resold for cash or used to satisfy share options but all rights attaching to them, including voting rights and any right to receive dividends are suspended whilst they are held in treasury. However, it should not be assumed that the Board will exercise any or all of this proposed authorisation. This power would be used only after careful consideration by the Directors, having taken into account market conditions prevailing at that time, the investment needs of the Company and its overall financial position. The Directors would exercise the proposed authority to purchase ordinary shares only if they considered it to be in the best interests of Shareholders and if the purchases could be reasonably expected to result in an increase in earnings per share.

As at 2 April 2015, options were outstanding to subscribe for 6,610,540 ordinary shares, representing 11.4 per cent of the issued share capital of the Company. The proportion of issued share capital represented by such share options would increase to 12.7 per cent if the full authority to purchase shares (existing and sought) is utilised by the Directors. There are no warrants outstanding and no treasury shares in issue. The authority sought in Resolution 10 is to replace the authority given at the General Meeting and will expire at the conclusion of the Annual General Meeting in 2016 or on 31 May 2016, whichever is the earlier.

Notice of Meetings (Resolution 11)

Under the Shareholders' Rights Regulations, the prescribed notice period for general meetings of a company is 21 days unless certain requirements are satisfied including that a special resolution of Shareholders is passed to allow notice of meetings to be given by way of 14 days clear notice. At the Annual General Meeting of the Company held in 2014 authority was granted by Shareholders to allow a shorter notice of 14 clear days. The Directors believe it is in the best interests of the Shareholders to retain the flexibility of a shorter notice period and intend to renew this authority at the Annual General Meeting by proposing a special resolution to allow notice of meetings to be given by way of 14 days clear notice. It is intended by the Directors that a shorter notice period

---

will be used where the flexibility is merited by the business of the meeting, where the matter is time sensitive and where it is thought to be to the advantage of Shareholders. The approval will be effective until the Company's Annual General Meeting in 2016, when a resolution will be proposed to renew the authority. In order to be able to call a general meeting on less than 21 clear days' notice, the Company must make a means of electronic voting available to all Shareholders at the time of calling the meeting.

Recommendation

The Directors believe that the adoption of all the resolutions to be put to the Meeting are in the best interests of the Company and its Shareholders and are most likely to promote the success of the Company for the benefit of Shareholders as a whole. The Directors unanimously recommend that you vote in favour of all the Resolutions to be proposed at the Annual General Meeting, as they themselves intend to do in respect of their own beneficial shareholdings which in aggregate amount to a total of 4,284,613 ordinary shares, representing approximately 7.4 per cent. of the existing issued ordinary share capital of the Company as at 2 April 2015, being the latest practicable date prior to publication of this letter containing the Notice of Meeting.

Yours sincerely

EXPLANATORY NOTES TO ACCOMPANY AGM NOTICE

A General Notes

The following notes explain your general rights as a Shareholder and your rights to attend and vote at the AGM or to appoint someone else to vote on your behalf:

1. Only holders of ordinary shares, or their duly appointed representatives, are entitled to attend, vote and speak at the Meeting. A member is entitled pursuant to Section 324 of the Companies Act 2006 to appoint (a) proxy(ies), who need not be (a) member(s) to attend, vote and speak on his/her behalf.

2. A Form of Proxy is enclosed and instructions for its use are shown on the form. The appointment of a proxy will not prevent a member from subsequently attending, voting and speaking at the Meeting in person.

3. If you wish, you may register the appointment of a proxy for the Meeting electronically, by contacting the Company's Registrar's website www.capitashareportal.com where full details of the procedures are given. The proxy appointment and instructions must be received by Capita Asset Services not less than 48 hours before the time for holding the Meeting or adjourned meeting or (in the case of a poll taken otherwise than at or on the same day as the Meeting or adjourned meeting) for the taking of the poll at which it is to be used.

4. (a) CREST members who wish to appoint a proxy or proxies through the CREST electronic proxy appointment service should follow the procedures described in the CREST Manual. CREST personal members or other CREST sponsored members, and those CREST members who have appointed (a) voting service provider(s), should refer to their CREST sponsor or voting service provider(s), who will be able to take the appropriate action on their behalf.

(b) In order for a proxy appointment or instruction made using the CREST service to be valid, the appropriate CREST message (a 'CREST Proxy Instruction') must be properly authenticated in accordance with Euroclear's specifications and must contain the information required for such instructions, as described in the CREST Manual. The message, regardless of whether it constitutes the appointment of a proxy or an amendment to the instruction given to a previously appointed proxy must, in order to be valid, be transmitted so as to be received by the issuer's agent (ID: RA10) not less than 48 hours before the time for holding the Meeting. For this purpose, the time of receipt will be taken to be the time (as determined by the timestamp applied to the message by the CREST Applications Host) from which the issuer's agent is able to retrieve the message by enquiry to CREST in the manner prescribed by CREST). After this time, any change of instructions to proxies appointed through CREST should be communicated to the appointee through other means.

(c) CREST members and, where applicable, their CREST sponsors or voting service providers should note that Euroclear does not make available special procedures in CREST for any particular messages. Normal system timings and limitations will therefore apply in relation to the input of CREST Proxy Instruction. It is the responsibility of the CREST member concerned to take (or, if the CREST member is a CREST personal member or sponsored member or has appointed (a) voting service provider(s) take(s)) such action as shall be necessary to ensure that a message is transmitted by means of the CREST system by any particular time. In this connection, CREST members and, where applicable, their CREST sponsors or voting service providers am referred, in particular, to those sections of the CREST Manual concerning practical limitations of the CREST system and timings. The CREST Manual can be reviewed at www.euroclear.com/CREST.

(d) The Company may treat as invalid a CREST Proxy Instruction in the circumstances set out in Regulation 35(5)(a) of the Uncertificated Securities Regulations 2001.

1. At the Annual General Meeting of the Company to be held on 18 May 2015 the votes will be taken on a show of hands unless a poll is demanded and the results will be released to the London Stock Exchange and published on the Company's website www.microgen.com.

6 A person to whom this Notice is sent who is a person nominated under Section 146 of the Companies Act 2006 to enjoy information rights (a 'Nominated Person') may, under an agreement between him/her and the Shareholder by whom he/she was nominated, have a right to be appointed (or to have someone else appointed) as a proxy for the Meeting. If a Nominated Person has no such proxy appointment right or does not wish to exercise it, he/she may, under such agreement, have a right to give instructions to the Shareholder as to the exercise of voting rights.

7 The statement of the rights of members in relation to the appointment of proxies in paragraphs 1 to 4 above does not apply to a Nominated Person. The rights described in these paragraphs can only be exercised by registered members of the Company.

8 Any corporation which is a member can appoint one or more corporate representatives who may exercise on its behalf all of the same powers as the corporation could exercise if it were an individual member provided that they do not do so in relation to the same shares.

9 Copies of any contract of service, letters of appointment and deeds of indemnity between the Directors and the Company or any of its subsidiaries (or a memorandum of the terms thereof) will be available at the Registered Office of the Company during normal business hours until the conclusion of the Meeting, and at the place of the Meeting from at least 15 minutes prior to the Meeting until its conclusion.

10 The Company, pursuant to the Uncertificated Securities Regulations 2001, specifies that only those Shareholders on the Register of Members as at 6.00 pm on Thursday 14 May 2015 (or, if the Meeting is adjourned, as at 6.00 pm on the day two working days prior to the date of the adjourned meeting) shall be entitled to attend in person or by proxy and vote at the Meeting in respect of the number of shares registered in their names at the time. Changes to entries on the ordinary register after 6.00 pm on Thursday 14 May 2015 (or if this Meeting is adjourned, changes to entries on the Register of Members after 6.00 pm two days prior to the date of any adjourned Meeting) shall be disregarded in determining the right of any person to attend or vote at the Meeting.

11 Under Section 319A of the Companies Act 2006, any member attending the Meeting has the right to ask questions in relation to the business of the Meeting. The Company must cause to be answered any such question relating to the business being dealt with at the Meeting but no such answer need be given if (a) to do so would interfere unduly with the preparation for the Meeting or involve the disclosure of confidential information; (b) the answer has already been given on a website in the form of an answer to a question; or (c) it is undesirable in the interests of the Company or the good order of the Meeting that the question be answered.

12 As at 2 April 2015 (being the latest practicable date prior to the publication of this Notice) the Company's issued share capital, and the total number of voting rights, consists of 58,030,520 ordinary shares of 6 3/7 pence each.

13 Shareholders are advised that, unless otherwise stated, any telephone number, website and email address set out in this Notice of Meeting, Form of Proxy or Chairman's letter should not be used for the purpose of serving information on the Company (including the service of documents or information relating to the proceedings at the Company's Annual General Meeting).

14 A copy of this Notice, and other information required by Section 311A of the Companies Act 2006 can be found at www.microgen.com.
