Chevron Responds to Reported Lawsuit by Federal District Attorney in Campos Brazil

Chevron Corporation (NYSE: CVX) said a Brazilian federal district
prosecutor has told reporters that he will file a civil lawsuit against
Chevron and other companies seeking a reported 20 billion reais ($10.7
billion) in damages, and an injunction stopping Chevron′s activities in
Brazil. Chevron has not received any formal notice of this action.
Chevron also has not received any instruction from the regulatory
agencies with oversight responsibility for our activities in Brazil
regarding suspension of our operations.

From the outset, Chevron responded responsibly to the incident at its
Frade Field and has dealt transparently with all Brazilian
authorities. ?The flow of oil from the source was stopped within four
days and the company continues to make significant progress in
containing any residual oil. ?Chevron has also continued to address the
surface sheen, which is now less than a single barrel. ?There have been
no coastal or wildlife impacts.
