Dear Overseas Registered Shareholder.

Issue of Shares and Options under non-renounceable Rights issue (Rights Issue).

The Company announced on 17 August a non-renounceable Rights Issue of one (1) new share for each five (5) shares of shares, together with attaching options of one (1) option for every three (3) shares issued under the Rights Issue to eligible shareholders on 31 August 2011. A copy of the Offer document, together with other information relating to the Rights Issue, has been released to the Australian Stock Exchange and is also posted on the Company’s website at www.immuron.com.

It is not practicable for the Company to comply with the securities laws of overseas jurisdictions having regard to the number of overseas shareholders, the number and value of the shares these shareholders would be offered and the cost of complying with the particular regulatory requirements in each relevant jurisdiction. Accordingly, the Rights Issue is not being extended to, and shares will not be issued to, shareholders with a registered address which is outside Australia, New Zealand and Israel.

The Offer does not, and is not intended to, constitute an offer in any place or jurisdiction in which, or to any person to whom, it would not be lawful to make such an offer or to issue the Offer document.

We thank you for your continued interest in Immuron Limited.

Yours faithfully
