PETRONAS Awards Talisman Energy the Kinabalu Oil PSC

Investment to increase production and oil recovery

CALGARY, ALBERTA--(Marketwire - May 28, 2012) - Petroliam Nasional Berhad (PETRONAS), the national oil company of
Malaysia, has formally awarded Talisman Malaysia Limited (Talisman Energy, TSX:TLM, NYSE:TLM) and PETRONAS Carigali Sdn.
Bhd. (PETRONAS Carigali) a new production sharing contract (PSC) for the continuing production, further development and
improved recovery of crude oil from the Kinabalu oil fields, which comprise the Kinabalu Main, Kinabalu East and
Kinabalu Far East fields, offshore Sabah ("Kinabalu Oil Fields"). The Kinabalu Oil Fields have a number of producing
mature fields, with significant development upside.

"We appreciate PETRONAS' vote of confidence and we are very excited about this opportunity," said Paul Blakeley,
Talisman's Executive Vice-President of International Operations East. "Talisman has a proven track record of growing
production and extending the life of mature fields, and the Kinabalu Oil Fields give us the opportunity to demonstrate
this in Malaysia. The PSC is also adjacent to the Talisman operated Sabah exploration block, which provides additional
upside in the region."

This new PSC is the first of a new "progressive volume-based" (PVB) PSC to be awarded by PETRONAS. The PVB PSC was
specifically designed to incentivize contractors to improve oil recovery and increase production from mature oil fields.

Talisman and PETRONAS Carigali plan to invest over US$1 billion to increase oil recovery and production over the life of
the PSC. This will add to the list of fields in Malaysia where improved oil recovery techniques are being used to
increase both production and reserves. Talisman will hold a 60% working interest and operate; PETRONAS Carigali will
hold the remaining 40%.

Ron Aston, Vice-President and Country Manager for Talisman Malaysia, noted the opportunities this new asset will present
for Talisman's employees and contractors. "This PSC will allow Talisman to offer new opportunities for career growth to
our existing Malaysian staff, many of whom have gained world-class experience on Talisman's existing assets in
Peninsular Malaysia. At the same time, development and production of the Kinabalu Oil Fields offers opportunities for
new jobs and new suppliers in Sabah, Labuan and across Malaysia."

The Kinabalu Oil Fields are currently operated by Shell, with the current PSC expiring in late December 2012. All
participants are working together to ensure a safe, successful transition.
