shareholders of TGS at the Annual General Meeting on 11 May 2021, the Board of

Directors of TGS Geophysical Company ASA authorized TGS to grant Performance

Stock Units (PSUs) and Restricted Stock Units (RSUs) under the 2021 Long Term

Incentive Plan to key employees of TGS on 10 August 2021.  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 2021 to 31 December 2023.  The granted PSUs

and RSUs were secured by free-standing warrants.

In accordance with the terms of the 2021 Long Term Incentive Plan, the PSUs and

vested PSUs.  In addition, 101,400 shares are issuable to fifty-four employees

for the vesting of the RSUs.
