GDF SUEZ Energy Resources Supports MetroNational’s Commitment to Environmental Responsibility

HOUSTON – JANUARY 13, 2015 – GDF SUEZ Energy Resources NA announced today it will provide
power to two of MetroNational’s office towers in Memorial City. This agreement strengthens
MetroNational’s commitment to environmental responsibility by incorporating Renewable Energy
Certificates (RECs) to One Memorial City Plaza and Three Memorial City Plaza.

MetroNational is one of Houston’s largest privately-held real estate investment, development, and
management companies and has implemented key environmental initiatives such as LEED certifications,
resource conservation, and pollution prevention.

With the assistance of energy partners Amerex Energy Services and GDF SUEZ, MetroNational will offset
100 percent of its electricity consumption with RECs for two years for two of its commercial office buildings.
Each REC represents the environmental attributes or benefits associated with a specific quantity of energy
generated from a renewable source, such as solar or wind. MetroNational will offset more than 20 million
kilowatts of its electricity use for the two buildings, which are currently pending LEED Existing Building
certification.

“MetroNational is proud to work with GDF SUEZ, which combines competitive pricing and reliability with a
commitment to sustainability. Through the GDF SUEZ team, we are able to integrate our energy
requirements and environmental needs—along with our best-in-class services—to our tenants,” said Loc
McNew, President and Chief Operating Officer of MetroNational.

Sam Henry, President and CEO of GDF SUEZ Energy Resources, said, “The agreement is a direct
reflection of MetroNational’s strong sustainability efforts and its unique approach to developing
communities and infrastructure in the Houston area. Moving forward we will continue to be a steward of the
environment and provide businesses in Houston with the tools and industry knowledge they need to make
the most of their supply and demand energy strategies.”

The RECs provided by GDF SUEZ will have a measurable impact on greenhouse gas emissions.
According to a calculator from the Environmental Protection Agency, this amount of green energy is
equivalent to the greenhouse gas emissions of achieved by avoiding 5,308 tons of waste diverted from
landfills; the drop in carbon dioxide emissions from displacing 1,666,654 gallons of gasoline; or the carbon
sequestered annually by 12,140 acres of U.S. forest.

This renewable energy supply is part of a larger, comprehensive energy procurement engagement in which
GDF SUEZ will provide electricity to all of MetroNational’s facilities over a multi-year period. “We
conducted a highly competitive bidding process, beginning with 14 retail suppliers and over 90 price points,
and GDF SUEZ emerged as the best suited supplier for MetroNational based on their competitive pricing,
products, and transactional capabilities,” said Jeff Shoaf, Senior Vice President of Amerex Energy
Services.
