                         ROC OIL COMPANY LIMITED ('ROC')
                             STOCK EXCHANGE RELEASE

               COMPLETION OF RENOUNCEABLE RIGHTS ISSUE BOOKBUILD


ROC is pleased to advise that last night it successfully completed the sale of
new shares representing the entitlements of ineligible shareholders or persons
who did not exercise their rights in its 3 for 8 Rights Issue.

The final clearing price in the Bookbuild was $3.10 per share which represented
a 1.9% discount to ROC's closing share price yesterday of $3.16.

Ineligible shareholders and persons who did not exercise their rights will
receive 40 cents for each share they were entitled to subscribe for under the
Rights issue, with the balance of $2.70 per share being received by ROC as the
Rights Issue application price. UK holders of shares through Depositary
Interests will receive such monies in pounds sterling.

ROC expects to issue the Rights Issue shares, including those sold under the
Bookbuild, on Friday, 8 December 2006, and, where applicable, to despatch
holding statements on Monday, 11 December 2006. The new shares are expected to
commence normal trading on ASX and AIM on Tuesday, 12 December 2006 and CREST
accounts in the UK are expected to be credited on that date.
