Talisman Energy Completes $1.5 Billion North Sea Transaction

Talisman Energy Completes $1.5 Billion North Sea Transaction With
Sinopec 
CALGARY, ALBERTA -- (Marketwire) -- 12/17/12 -- Talisman Energy Inc.
(Talisman) (TSX:TLM) (NYSE:TLM) today announced the completion of its
joint venture transaction with Addax Petroleum UK Limited (APUK), an
indirect wholly-owned subsidiary of China Petrochemical Corporation
(Sinopec Group) following receipt of government and regulatory
approval.  
"We are very pleased to be partnering with Sinopec in the UK North
Sea," said Hal Kvisle, President and CEO of Talisman Energy Inc.
"This transaction supports a number of Talisman's key priorities. The
proceeds will be used to strengthen our balance sheet, fund our
global capital program and give us the financial flexibility to
invest in future opportunities. Sinopec will now fund 49% of the UK
capital program, allowing us to increase overall investment in the
assets, which will lead to improved operational performance and a
stronger UK North Sea business. We look forward to working with
Sinopec in the years ahead." 
The completion follows the original announcement of the transaction
in July this year. Sinopec Group has acquired a 49% equity interest
in Talisman's UK North Sea business, Talisman Energy (UK) Limited
(TEUK), for $1.5 billion. Talisman will continue to hold 51% of the
joint venture company. The UK North Sea will be a smaller part of
Talisman's overall portfolio, but remains an important part of its
North Sea business. 
The focus of the joint venture will be to continue investment in
asset integrity and improve ongoing operating performance as well as
accelerating infill drilling, unlocking additional infrastructure-led
exploration opportunities and executing major projects, thereby
extending field life and deferring decommissioning.  
Talisman Energy (UK) Limited will be renamed Talisman Sinopec Energy
UK Limited.  
Notes to Editors 
Sinopec Group has acquired 49% of the shares of TEUK for $1.5
billion, before adjustments for working capital and interest,
creating an incorporated joint venture in which Talisman will
continue to hold 51% of the shares. This will proportionately reduce
Talisman's share of capital spending, production and abandonment
liabilities for its UK business.  
Talisman Sinopec Energy UK Limited will operate the assets, and
Sinopec Group will appoint select personnel into key positions within
the organization, strengthening an already strong team. The joint
venture company is based in Aberdeen, Scotland and employs 564
full-time employees, with approximately 1,950 core contractors.
