Dear Sirs,

Petrovietnam is very pleased to receive CLJOC’s letter ref. No. 1131/OPE-2020 dated 15th December 2020 regarding the achievement of 2020 production target. Petrovietnam hereby would like to congratulate and express our great appreciation towards your achieving oil production targets assigned by the MC for the year 2020 on 29th November 2020, which was 32 days ahead the schedule.

The above success is very much attributed to the tireless and innovative efforts of the Operator, on the basis of invaluable supports from the Authorities and especially the relevant Partners.

Petrovietnam look forward to continuing our close collaboration with Partners and committed support to Operator CLJOC in establishing practical targets for next year and succeeding in achieving them in the same way as we have done this year.

Once again, thank you.

Sincerely yours,

Dr. Le Manh Hung
