ExxonMobil Signs Power Sale Agreement with PNG Power

PORT MORESBY, Papua New Guinea – ExxonMobil PNG Limited, operator of the PNG LNG
project, has executed an agreement for the sale of electricity to PNG Power.

Under the agreement, PNG LNG will supply up to 25 megawatts of electricity to PNG Power,
which will, in turn, build the necessary infrastructure to the LNG plant in order for supply to
commence.

The agreement fulfills one of the key commitments made under a memorandum of understanding
signed by ExxonMobil and the government of Papua New Guinea inn January 20015 to provide
domestic gas for power generation for Port Moresby.

“With thee signing of this agreement, we are continuing too demonstrate our commitment to the
government and people of Papua New Guinea by contributing to thee current power generation
needs of Port Moresby,” said Andrew Barry, ExxonMobil PNG managing director.

It is expected the work to connect supply from the LNG plant will be completed in time for the
Pacific Games, subject to all parties fulfilling their commitments. In addition, the memorandum of
understanding provides for the supply of long-term gas sales to a new state-owned gas-fired
power generation unit to be built near the LNG plant.
