SUCCESSFUL COMPLETION OF RETAIL ENTITLEMENT OFFER AND RETAIL
BOOKBUILD

Orica Limited (“Orica”) has successfully completed the retail component of its accelerated
pro-rata Entitlement Offer. The Retail Entitlement Offer received a strong level of support
from Orica’s eligible retail shareholders with more than 50% of shares available under the
Retail Entitlement Offer taken up by eligible retail shareholders.
Approximately 6.3 million shares were available for the Retail Bookbuild, which was
conducted on 21 August 2008. The Retail Bookbuild was well supported, attracting bids
from both new and existing Australian and international institutional investors. The
bookbuild clearing price was $22.60 per share, compared to the $22.50 Offer Price.
Accordingly, eligible retail shareholders who elected not to take up their entitlements and
ineligible retail shareholders will receive $0.10 for each share not taken up. This payment is
expected to be sent to these shareholders around 5 September 2008.
The Retail Entitlement Offer and associated bookbuild, will raise approximately $295 million,
in addition to the $604 million raised through the Institutional Entitlement Offer and
Institutional Bookbuild in late July. The allotment of new shares under the Retail Entitlement
Offer and Retail Bookbuild is expected to take place on Friday, 29 August 2008 with those
shares to commence trading on the same day. Following allotment of these shares, Orica
will have approximately 359.2 million shares on issue.
