The Egyptian General Petroleum Corporation (EGPC) was hit by a bribery and information leak case in 2007, according to Egypt Oil & Gas, where six EGPC officials were convicted on charges of disclosing secret information to clients and giving them special advantages in EGPC bids in return for money and gifts. Several other oil and gas companies have been involved in corruption cases. For example Petrogas was investigated for importing defect gas valves, and Al-Nasr Petroleum Company and Petroleum Marine Service Company both saw top officials charged with being paid LE 2 million in bribes by companies as kickbacks for information on pricing lists in bids or the acquisition of contracts.
