Migration of Common Shares and transfer to new restricted DI line

TyraTech, Inc. (AIM: TYR and TYRU), a life sciences company focusing on nature-derived insect and parasite control products, announces that, the Company intends to carry out a sponsored migration (the "Migration") in relation to certain of its common shares of US$0.001 in the Company ("Common Shares"), which trade on the Company's restricted trading line under TIDM 'TYR' with ISIN number USU890581080, to the Company's unrestricted trading line under TIDM 'TYRU' with ISIN number US90239R2031. Removal of the trading restrictions allows the Common Shares to be: (i) transferred to its unrestricted trading line (TIDM: TYRU); and (ii) settled (at the election of the shareholder), by means of Depositary Interests, through the CREST electronic settlement system.

In addition, in accordance with Regulation (EU) No. 909/2014 of the European Parliament and of the Council of 23 July 2014 on improving securities settlement in the European Union and on central depositaries (the "EU Regulation") which requires all shares listed on AIM to be capable of electronic settlement, as of 1 September 2015 the existing restricted line of stock which trades under the ticker symbol TYR with ISIN number USU890581080 will be replaced by a new restricted line (the "New Restricted DI Line") which is in compliance with the requirements of the EU Regulation and will allow shareholders of restricted Common Shares to deposit their Common Shares into CREST in exchange for Depository Interests and trade such Depository Interests in uncertificated form on AIM (the "Transfer Programme"). Common Shares which participate in the Transfer Programme will retain their legend and thus the restrictions on transfer. The New Restricted DI Line will continue to use the ticker symbol TYR and ISIN number USU890581080.

In the event that shareholders choose not to participate in the Migration, and take no action to participate in the Transfer Programme, their Common Shares will automatically transfer to the New Restricted DI Line on 1 September 2015 when the existing restricted line ceases trading. Common Shares which transfer automatically will continue to be held in certificated form and will retain their legend and thus the restrictions on transfer, but will continue to be admitted to AIM, however shareholders should note that certificated stock is not capable of electronic settlement in accordance with the EU Regulation and will need to be dematerialised prior to electronic settlement. No Common Shares will be deposited into CREST without the positive action of the relevant shareholder.

The Company is making the necessary arrangements to allow shareholders to participate in the Migration and the Transfer Programme, as appropriate, and documents containing further instructions on how to participate have been sent today to shareholders who the Company believes are eligible to migrate or transfer their Common Shares.

In general, under US securities law, Common Shares that have been in issue for more than one year and are not held by an 'affiliate' of the Company qualify for characterisation as unrestricted Common Shares ("Unrestricted Common Shares"). An affiliate for this purpose is a person that directly, or indirectly through one or more intermediaries, controls, or is controlled by, or is under common control with, the Company or a director or officer of the Company. All Unrestricted Common Shares are eligible for migration to, and trading on, the Company's unrestricted TYRU line.

Following the Migration and Transfer Programme, the Company will continue to have a total of 262,333,111 Common Shares admitted to AIM (excluding those Common Shares admitted and not allotted under the blocklisting announced on 25 February 2011). The Company holds 1,084,413 Common Shares in treasury and these treasury shares trade under the symbol TYR.
