Bw Offshore Ltd. — M&A Activity 2010

Jun 30, 2010

Notice regarding Voluntary Exchange Offer

NOT FOR PUBLIC DISTRIBUTION, DIRECTLY OR INDIRECTLY, IN OR INTO THE UNITED

STATES OF AMERICA, CANADA, AUSTRALIA OR JAPAN

30 June  2010 - Reference is made to the stock exchange notice (the "Notice")

from BW Offshore Limited ("BW Offshore" or "BWO") of 21 June 2010 regarding an

intention to make a voluntary exchange offer (the "Offer") for all of the shares

of Prosafe Production Public Limited ("Prosafe Production") not currently owned

by BW Offshore.

As further detailed in the Notice, the consideration of 1.2 BWO shares and NOK

5.25 in cash per Prosafe Production share is conditional upon the sale by

Prosafe Production of its Turret Business (on conditions as announced by Prosafe

Production in its stock exchange notice of 22 March 2010) being completed no

later than two Norwegian business days prior to expiry of the acceptance period

for the Offer. If this condition is not met, then the consideration in the Offer

will be 1.2 BWO shares and NOK 2.0 in cash per Prosafe Production share.

According to a stock exchange notice from Prosafe Production today, 30 June

2010, the Letter of Intent to sell the Turret Business has been extended until

after the Offer has been concluded and the future ownership structure of Prosafe

Production has been clarified.

The effect of this extension will be that the Offer consideration is reduced to

1.2 BWO shares and NOK 2.0 in cash per Prosafe Production share and it will

thereby not be possible for the shareholders of Prosafe Production to get the

benefit of possible excess value stemming from a sale of the Turret Business as

contemplated by the higher consideration of 1.2 BWO shares and NOK 5.25 in cash

in the Offer.

Due to these circumstances, BW Offshore is considering whether to withdraw the

intended Offer if this helps facilitate a swift closing of the sale of the

Turret Business by Prosafe Production for the benefit of all shareholders.
