are excluded from the statistics.

PGS will release its Q4 and preliminary full year 2018 financial results on
Thursday January 31, 2019, at approximately 7:00am Central European Time (CET).
A corresponding presentation is scheduled for 09:00am CET the same day.

*The term "cold-stacked" is used when a vessel is taken out of operation for an
extended period of time. Costs are reduced to a minimum, with the vessel
preserved for a long idle time, all or most in-sea seismic equipment removed
from the vessel, and typically the crew required to operate the vessel is
terminated.
