Form 604 regarding shareholding in Carbon Energy Limited

Attached is a Form 604 (Notice of change of interests of substantial holder) given in relation to Incitec Pivot Limited's (IPL) shareholding in Carbon Energy Limited (CNX).

This notice details changes in IPL's relevant interest in CNX shares since the date of IPL's last Form 604 was given to ASX and CNX on 3 March 2010. The changes have been primarily as a result of dilution to IPL's holding following various capital raisings and share issues undertaken by CNX.

Yours faithfully
