NOT FOR RELEASE, PUBLICATION OR DISTRIBUTION, IN WHOLE OR IN PART, DIRECTLY OR INDIRECTLY, IN OR INTO THE UNITED STATES, CANADA, AUSTRALIA, HONG KONG OR JAPAN, OR ANY OTHER JURISDICTION IN WHICH THE RELEASE, PUBLICATION OR DISTRIBUTION WOULD BE UNLAWFUL OR WOULD REQUIRE REGISTRATION OR OTHER MEASURES. THIS ANNOUNCEMENT DOES NOT CONSTITUTE AN OFFER OF ANY OF THE SECURITIES DESCRIBED HEREIN.

Reference is made to the stock exchange release from Petroleum Geo-Services ASA ('PGS' or the 'Company') published 11 November 2015, regarding the contemplated private placement.

PGS announces today that it has successfully raised approximately NOK 919.6 million in gross proceeds through a placement of 21,779,999 new shares (the 'New Shares') and 1,800,000 treasury shares, towards Norwegian and international institutional investors, at a price of NOK 39 per share (the 'Private Placement'). The New Shares to be issued represent approximately 9.99% of the current issued share capital in the Company.

The proceeds from the Private Placement will be used to strengthen the Company's balance sheet and liquidity position as well as for general corporate purposes and will further strengthen the Company's ability to take active part in, and benefit from, restructuring or distress driven opportunities emerging in the marine seismic industry.

In order to ensure timely delivery of shares to investors, the Managers have entered into a share lending agreement with Ferd AS. On the basis of this arrangement, the investors who are allocated shares in the Private Placement will receive existing and unencumbered shares in the Company that are already listed on Oslo Børs. Subject to completion, payment and delivery of allocated shares to the investors is expected to be on or about 16 November 2015.

The new shares to be issued by the Company will be issued to the Managers and used to settle the share loan from Ferd AS, provided, however, that the 2,178,000 shares allocated to Ferd AS in the Private Placement will be issued directly to Ferd AS.

The New Shares in the Private Placement will be issued by the board of directors of PGS, pursuant to an authorization granted at the Company's annual general meeting on 13 May 2015. The total number of issued shares in The Company, after issuance of the New Shares, will be 239,579,996 shares, each with a nominal value of NOK 3.0, corresponding to a share capital of NOK 718,739,988. The total number of treasury shares held by the Company after the Private Placement is 1,404,174. The Board of Directors has resolved to set aside the pre-emptive rights of the existing shareholders. The Board of Directors considers this to be in the best interests of the Company and the shareholders since it will allow the Company to raise capital more quickly, at a lower discount and with significantly lower transaction costs than a rights offering would allow.

The Company has agreed not to offer, issue, sell or otherwise dispose of (or announce an intention of doing so) any other shares of the Company or any securities convertible into or exchangeable for or carrying rights to acquire other shares of the Company for a period of 90 days following settlement of the Offering without the consent of the Managers.

ABG Sundal Collier and Nordea Markets acted as Joint Global Coordinators and Joint Bookrunners for the Private Placement.
