MyCelx Shares to be Traded on CREST

MyCelx announces that it has introduced a Depository Interest programme with Capita IRG Trustees Limited ("Capita") to enable its Common Shares to be traded in CREST.

At the time of Admission of MyCelx's Common Shares to trading on AIM on 4 August 2011, restrictions on transfer under the United States securities laws required that the Common Shares had to be held in certificated form for a period of at least 12 months following Admission. In its Admission Document, MyCelx stated that Depository Interests representing Common Shares were expected to be eligible for admission to CREST after the end of the 12 month period.

The Depository Interest programme will be effective from 4 September 2012. Under this programme, Capita will issue Depository Interests to qualifying shareholders on a one-for-one basis for each Qualifying Security in the Company held by that qualifying shareholder. Capita will appear on the register of members of the Company as the shareholder but the beneficial interest and all rights in the relevant common shares will remain with the original shareholder. The benefit of dematerialisation is that the Depository Interests can be held and transferred through CREST, thereby enhancing the liquidity of the Company's securities.

As a result of the Depository Interest programme, there will be two lines of stock in MyCelx as of 4 September 2012, relating to both the restricted and the unrestricted lines of stock.

In order to facilitate the process, the existing Common Shares (ISIN USU624551078) will trade with the new ticker MYXR, effective as of today.

As of 4 September, when the new line of stock is admitted to trading on the London Stock Exchange, the unrestricted Common Shares (ISIN US62847T2024) will trade under the ticker MYX and will be able to be traded as Depository Interests in CREST. The restricted Common Shares will continue to trade outside CREST, due to restrictions imposed by United States securities laws, with the ticker MYXR.

The Company has sent to its shareholders a letter explaining the process of moving shares between the lines of stock and dematerialising them into Depositary Interests. The form of this letter is available on the Company's website at www.mycelx.com.
