Details of the PrimaryBid Offer

The Company highly values its retail investor base which has supported the Company alongside institutional investors over several years. Given the longstanding support of retail shareholders, the Company believes that it is appropriate to provide eligible retail and other investors the opportunity to participate in the PrimaryBid Offer. The Company is therefore making the Offer available exclusively through PrimaryBid.

Eligible retail and other investors may participate in the PrimaryBid Offer of New Ordinary Shares on a first come, first served basis, exclusively through PrimaryBid. There is a minimum subscription of £100 per investor under the terms of the PrimaryBid Offer which is open to existing shareholders and other investors subscribing via PrimaryBid.com. Any investment request in excess of £100,000 will require the Company's consent and may be subject to scale back.

The PrimaryBid Offer is offered under the exemptions against the need for a prospectus allowed under the prospectus rules made in accordance with the EU Prospectus Directive 2003/71/EC in relation to offers of securities to the public and the admission of securities to trading on a regulated market ("Prospectus Rules"). As such, there is no need for publication of a prospectus pursuant to the Prospectus Rules, or for approval of the same by the Financial Conduct Authority in its capacity as the UK Listing Authority. The PrimaryBid Offer is not being made into any jurisdiction where it would be unlawful to do so.

For further details of eligibility and how to subscribe to the Offer please refer to the PrimaryBid.com website at www.PrimaryBid.com. The terms and conditions on which the PrimaryBid Offer is made, including the procedure for application and payment for New Ordinary Shares, is available to all persons who register with PrimaryBid.com.

Investors should make their own investigations into the merits of an investment in the Company. Nothing in this announcement amounts to a recommendation to invest in the Company or amounts to investment, taxation or legal advice.

It should be noted that a subscription for New Ordinary Shares and investment in the Company carries a number of risks. Investors should consider the risk factors set out on PrimaryBid.com before making a decision to subscribe for New Ordinary Shares. Investors should take independent advice from a person experienced in advising on investment in securities such as the New Ordinary Shares if they are in any doubt.
