The offer to subscribe for Offer Shares through the exercise of Rights is referred to as the Offering.

Each Ordinary Share held immediately after the close of trading in Ordinary Shares on NYSE Euronext in Amsterdam (Euronext Amsterdam) at 17:40 hours, Central European Time (CET), on 3 April 2013 (the Record Date) will entitle its holder to one (1) Right.

Eligible Persons may, subject to applicable securities laws, subscribe for Offer Shares by exercising Rights from 09:00 hours CET on 4 April 2013 until 15:00 hours CET on 17 April 2013 (the Exercise Period). If an Eligible Person has not exercised his Rights by the end of the Exercise Period, they can no longer be exercised. Once an Eligible Person has validly exercised his Rights, that exercise cannot be revoked or modified, except in certain circumstances as set out in “The Offering – Exercise Period”.

SBM Offshore has applied for admission to listing and trading of the Rights on Euronext Amsterdam. Listing and Trading is expected to commence under the symbol “SBMOR” at 09:00 hours CET on 4 April 2013 and will continue until 17:40 hours CET on 16 April 2013.
