PetroChina Company Limited (PetroChina) and China Petrochemical Corporation (Sinopec), following
friendly consultations, have reached consensus on mutual supply of crude oil in the year of 2014 and hereby enter into this Agreement (this Agreement).



|I. | Mutual Supply and Cross Supply of Crude Oil

2.25 million tons of blended oil produced at the Daqing Oil Region (including replacement crude oil of 0.15 million tons), 0.70 million tons of oil produced at the Jizhong Oil Region, 1.10 million tons of oil produced at the
Changqing Oil Region, and 30,000 tons of oil produced at PetroChina Zhejiang Exploration Company.

In 2014, Sinopec shall supply PetroChina with 1.881 million tons of domestic onshore crude oil, including 0.40 million tons of blended oil produced at the Tahe Oil Region, 0.50 million tons
of oil produced at the Chunguang Oil Region, 0.40 million tons of oil produced at the Chunfeng Oil Region, 45,000 tons of oil produced at the Yanqi Oil Region, 0.53 million tons of oil produced at the Shengli Oil Region, and 6,000 tons of

The above
1.10 million tons of oil produced at the Changqing Oil Region supplied by PetroChina to Sinopec shall include 0.50 million tons of oil supplied in exchange for Sinopecs supply of the equal amount of oil produced at the Chunguang Oil
Region. The parties shall implement such crude-oil exchange strictly on an equal-amount basis and shall ensure the free flow of their respective downstream operations of the oil regions and ensure the resource supply to their respective refineries.
In case either party fails to supply the agreed amount in full, the other party may reduce its supply by an equal amount.
