The Netherlands: Boskalis Raises Offer for Dockwise

With reference to the press release of 26 November 2012 (the Initial Announcement) and subsequent release on 17 December 2012, in which Boskalis announced its intention to make an offer for Dockwise, Boskalis today confirms it is making an all cash voluntary public offer (through its wholly owned subsidiary Boskalis Holding B.V.) for all the issued and outstanding ordinary shares of Dockwise.

The Offer is being made in Euros at an offer price of EUR 18.50 per Share (cum dividend), which is an increase of 50 euro cents relative to the 17 December announcement.

The offer price represents:

• a premium of approximately 74% relative to the closing price of EUR 10.66 per share of Dockwise as per 23 November 2012

• a premium of approximately 45% relative to the average closing price of an ordinary share of Dockwise during the last 3 months; and

• a premium of approximately 40% relative to the average closing price of an ordinary share of Dockwise during the last 12 months

The offer values Dockwise at EUR 733 million (approx USD 967 million) with an enterprise value of approximately EUR 1.25 billion (approx USD 1.649 billion) .

Boskalis strongly believes that the Offer price represents full and fair value for the shareholders of Dockwise.

MORE THAN 83.5% COMMITTED TO THE OFFER

In addition to HAL Investments B.V. and Project Holland Deelnemingen B.V., other shareholders, holding approximately 11.1% of the Shares, have now also agreed to an irrevocable undertaking to support and accept the Offer in accordance with its terms, subject to customary conditions. None of these shareholder have received information that will not be included in the offer document.

Together with the Shares acquired by Boskalis, in total approximately 33% of the Shares, this means that approximately 83.5% is already committed to the Offer.
