Dear Kim-Ly,

ImpediMed Limited – Request for trading halt under Listing Rule 17.1

ImpediMed Limited ( ImpediMed ) requests a trading halt in its ordinary shares and options from the commencement of trading today, Tuesday 1 May 2012 until the commencement of trading on Thursday 3 May 2012.

In accordance with Listing Rule 17.1, I advise that:

• (a) ImpediMed is seeking the trading halt pending the making of an announcement to the market in relation to a proposed capital raising. The price and number of shares which will be issued is yet to be determined;

• (b) ImpediMed is seeking the trading halt to assist in managing its disclosure obligations in relation to the proposed capital raising and maintaining an orderly market in the trading of the Company’s shares and to ensure that trading does not take place in an uninformed market;

• (c) ImpediMed requests that the trading halt last until the earlier of the commencement of trading on Thursday 3 May 2012 or when ImpediMed makes an announcement to the market concerning the proposed capital raising;

• (d) ImpediMed is not aware of any reason why the trading halt should not be granted.
