Ann: Baragatan-1A Update, page-2

Nido Petroleum Limited (ASX: NDO) (“Nido” or the “Company”) on behalf of SC 63 Joint Venture
partners PNOC-EC and Dragon Oil (Philippines SC 63) Limited wishes to advise that the Baragatan-
1A well as at 23 June 2014 was preparing to drill ahead in 8 ½ “ hole at 2,329 meters Measured
Depth (2,055.9 meters TVD sub-sea).

Drilling progress since the 9 5/8” casing point has taken longer than predicted due to slow drilling of
the Pagasa Formation claystone and elevated formation pressures. Nido expects to be at the
primary reservoir objective in the next few days, based on forward drilling estimates.

Nido wishes to further advise that during the drilling of the Pagasa Formation a gross interval from
1,977 - 2,004 meters Measured Depth (1,785 - 1,805 meters TVD sub-sea) comprising mainly
sandstone and a gross interval from 2,207 – 2,236 meters Measured Depth (1,960 – 1,982 meters
TVD sub-sea) comprising limestone contained elevated mud-log gas readings (C1 to C5) with oil
shows recorded in the upper part of the limestone interval.

It is unclear as to the significance or otherwise of these mud-log gas shows and this data will be
considered for further evaluation once the primary reservoir objective has been drilled and the well
has reached its planned Total Depth of 3,164 meters Measured Depth (2,700 meters TVD sub-sea).
