Oslo, Norway (26 August 2020) - In February 2019, TGS implemented an Employee

Share Purchase Plan (ESPP) pursuant to which eligible employees are allowed to

operates in six-month periods, and at the end of each period, employees have the

option to purchase stock at a 15% discount to the market price at the time of

purchase.  The plan sets a maximum purchase of 100 shares per employee per six-

month period.  ESPP dividends are reinvested in shares.
