SHORT HILLS, N.J. and KILGORE, TX, May 5, 2008 – Energy Capital Partners (“ECP”) and Martin Resource Management Corporation (“MRMC”) announced today the formation of Cardinal Gas Storage Partners LLC (“Cardinal”), a 50:50 joint venture focused on the development, construction, operation and management of natural gas storage facilities throughout North America.

Cardinal, through its wholly-owned subsidiary Arcadia Gas Storage LLC, is currently constructing a 13.8Bcf high deliverability salt dome natural gas storage facility in multiple caverns located near Arcadia, Louisiana. Cardinal has plans to develop additional natural gas storage facilities in the future.

“This business has compelling fundamentals as natural gas demand and volatility will increase in the future creating a need for additional natural gas storage capacity,” said Tom Lane, a partner of Energy Capital Partners. “The combination of ECP’s and MRMC’s shared vision and complementary skills will position Cardinal exceedingly well to achieve our goals,” he added.

Ruben Martin, President of MRMC, added “We are very pleased to have ECP as our joint venture partner in the natural gas storage business. Cardinal has an excellent foundation in the Arcadia facility and we look forward to building on that foundation with the development of additional strategically located natural gas storage assets with our experienced team and resources.”
