Forward Looking Statement

All statements in this press release other than statements of historical fact

are forward-looking statements, which are subject to a number of risks,

uncertainties and assumptions that are difficult to predict, and are based upon

assumptions as to future events that may not prove accurate. These factors

include TGS' reliance on a cyclical industry and principal customers, TGS'

ability to continue to expand markets for licensing of data, and TGS' ability to

acquire and process data product at costs commensurate with profitability, as

well as volatile market conditions, which have been exacerbated by the COVID-19

pandemic and the severe drop in oil prices.  Actual results may differ

materially from those expected or projected in the forward-looking statements.

TGS undertakes no responsibility or obligation to update or alter forward-

looking statements for any reason.
