  AN26: Talisman Energy Inc.: Talisman Energy Completes $1.5 Billion North Sea
  Transaction with Sinopec

UK Regulatory Announcement

CALGARY, Alberta

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

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


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.
