MXenergy Enters Texas Market
Following Agreement with Vantage Power Services

Stamford, Conn., May 17, 2007 -MXenergy and Vantage Power Services, L.P. have completed a transaction that transfers Vantage's power customers in Texas to MXenergy. MXenergy will begin supplying power to Vantage's nearly 2,500 former residential and commercial service locations on May 17, 2007.

No action is required from customers in order to transition their electricity service from Vantage to MXenergy, and all contracts will be honored in full. Vantage customers will continue to receive reliable and uninterrupted service with superior customer service standards during the transition.

"MXenergy is very excited to enter the Texas deregulated power market, where we believe we can offer a truly differentiated product to customers," said Jeffrey Mayer, president and CEO of MXenergy.

Nearly all of the Vantage employees will join the MXenergy team and relocate to its Houston office following a brief transition period. Together, the newly formed team will put considerable marketing resources into growing MXenergy's residential and commercial customer base in the state.

"As one of North America's largest natural gas and electricity suppliers, MXenergy is well-equipped to serve our customers with the same high standards they have come to expect," said T. Pat Harrison, president of Vantage Power Services. "We look forward to working together to provide Texas residents and businesses with solutions to serve their energy needs for years to come."
