                        Twiga South-1 Drilling Update

31 October  2012  - Following  media  speculation  in Kenya,  Tullow  Oil  plc 
(Tullow) announces that the  Twiga South-1 exploration  well in onshore  Kenya 
Block 13T  has successfully  encountered  oil. Drilling  is on-going  and,  as 
previously stated by partners Africa Oil Corp (Africa Oil) on October 26 2012,
an announcement of the  drilling result is expected  in early to  mid-November 
after target depth has been achieved  and necessary sampling and analysis  has 
been completed.

The Twiga South-1structure is the second prospect  to be tested as part of  a 
multi-well drilling campaign in Kenya and Ethiopia and is the first  discovery 
in block  13T following  the Ngamia-1  discovery earlier  this year  in  Block 
10BB.

Tullow has a 50% operated interest in  the Twiga South-1 well with Africa  Oil 
holding the remaining 50% interest.
