shareholders of TGS at the Annual General Meeting on 11 May 2022, the Board of

Directors of TGS ASA authorized TGS to grant Performance Stock Units (PSUs) and

Restricted Stock Units (RSUs) under the 2022 Long Term Incentive Plan to key

employees of TGS on 9 August 2022.  Each RSU represented the right to receive

one share, while each PSU represented the right to receive a maximum of one

share depending on performance against target metrics during the measurement

period of 1 January 2022 to 31 December 2024.  The granted PSUs and RSUs were

PSUs.  In addition, 107,367 shares are issuable to sixty-seven employees for the

vesting of the RSUs.
