The 2019 Authorisation will in addition authorise the Board of Directors to cancel shares repurchased on or before 17 April 2021. Under the 2019 Authorisation, the Company or any direct or indirect wholly-owned subsidiary of the Company will be authorised to purchase shares subject to a) the maximum price to be paid for such shares not exceeding 125% of the average closing price for such shares on the Oslo Børs for the five most recent trading days prior to such purchase and b) the minimum price to be paid for such shares shall not be less than the par value (i.e. \$2.00 per share) thereof and for a volume not exceeding 10% of the issued share capital in aggregate further provided such purchases are in conformity with Article 430- 15 of the Luxembourg Company Law.
