Dear all employees,

Although the on-going COVID-19 controlled measures are easing up, it is still paramount for all of us to
continue to be vigilant of risks and to keep yourself and others safe.

For those working for our client’s, PTTEP, Thai Offshore Assets, there is a clear instruction on how to
conduct yourselves during the 7 days quarantine period which is attached herein for your review. I would
like to ask for your kind support and cooperation to strictly follow the protective measures/instructions
given.

The company requires a very high level of responsibility, cooperation, and support from all staff members.
During this critical period, our commitment to all our clients is that we remain fully operational and ready to
support. All our Head Office staff members remain fully contactable via emails and mobile lines to the
servicing of our clients and all of you.

The safety of yourself and that of our clients have always been our number one priority. If you have any
concerns or questions, please do not hesitate to contact our company’s representative, K. Phuwanai S.

Thank you and be safe.
