NOT FOR RELEASE, PUBLICATION OR DISTRIBUTION, DIRECTLY OR INDIRECTLY, IN OR INTO THE UNITED STATES, CANADA, AUSTRALIA OR JAPAN EMGS - Subsequent Offering Oslo, 8 July 2010: Electromagnetic Geoservices ASA ("EMGS" or the "Company" - OSE: EMGS) Reference is made to the stock exchange release dated 22 June 2010 regarding a private placement of new shares in the Company ("Private Placement") and a possible subsequent offering ("Subsequent Offering"). Due to the prevailing market conditions, with the shares of the Company trading below the subscription price in the Private Placement and in a Subsequent Offering, the Board of Directors of the Company has decided not to have a Subsequent Offering. Shareholders of the  Company  as  at  21 June  2010 (as recorded in VPS on 24 June 2010 and visible  in the VPS on  25 June 2010) who were not contacted by the Managers to participate in the Private Placement or who did not participate or leave an order in the Private Placement, will have had the opportunity to acquire shares in the Company at a price less than the subscription price in a Subsequent Offering, and a Subsequent Offering is therefore not required to address the interests of such shareholders.
