AEI Expands into Pakistan, Strengthens Asian Presence

HOUSTON--(Business Wire)--
AEI announced today that it has acquired a controlling interest in
DHA Cogen Limited (DCL), located in Karachi, Pakistan. Closing of the
acquisition, which includes AEI's right to hold up to a 52.99 percent
interest in DCL, occurred July 18. The terms of the transaction have
not been disclosed.

While the transaction marks AEI's first venture into the Middle
East, the DCL acquisition strengthens AEI's overall Asian presence.
AEI recently acquired Luoyang Yuneng Sunshine Cogeneration Co., Ltd.
in China, and previously acquired gas distribution franchises through
the acquisitions of Beijing MacroLink Gas Co., Ltd. and Tongda Energy
Private Limited.

"We are pleased to enter the Pakistani market and establish a
presence in this fast-growing economy," Emilio Vicens, Vice President
of Business Development, said of the transaction. "This acquisition
strengthens our presence in Asia and demonstrates our commitment to
growing AEI's platform in this region."

DCL consists of a 94-megawatt combined-cycle gas-fired power plant
and a water desalination facility. It is the first desalination
facility in Pakistan. Achieving commercial operation on April 17,
2008, DCL currently sells all its power through a 30-year Power
Purchase Agreement with Karachi Electric Supply Company, and its steam
is used to produce three million gallons of desalinized water per day.
This water serves approximately 100,000 households daily. Located in
the heart of Karachi, DCL helps alleviate the area's chronic water
shortage while boosting the city's power supply.
