Tortoise Capital Advisors, LLC Completes Sale of Controlling Interest to Mariner Holdings and Tortoise Managers

Strategic partnership to build value for asset management clients with innovative products and thought leadership

LEAWOOD, Kan. – Sept. 15, 2009 – Tortoise Capital Advisors, LLC (Tortoise) announced today that the sale of all of its ownership interests to a holding company formed by its five founding Managing Directors and Mariner Holdings, LLC (Mariner) has closed. Tortoise serves as the adviser of Tortoise Energy Infrastructure Corp., Tortoise Energy Capital Corp., Tortoise North American Energy Corp., Tortoise Capital Resources Corp. and Tortoise Power and Energy Infrastructure Fund, Inc. (NYSE: TYG, TYY, TYN, TTO and TPZ, respectively), as well as a private fund and certain private accounts. Mariner will own a majority stake in Tortoise. Tortoise Managing Directors Kevin Birzer, Zachary Hamel, Ken Malvey, Terry Matlack and David Schulte will own in the aggregate approximately 35 percent of Tortoise and each has signed an employment commitment. Management of Tortoise, its Investment Committee and its funds will remain unchanged by the close of the transaction. Tortoise has also initiated an equity ownership plan in which initially four additional senior Tortoise employees will purchase equity.

"The Tortoise management team is enthused about teaming up with Mariner to purchase Tortoise Capital Advisors," said Kevin Birzer, Senior Managing Director of Tortoise Capital Advisors. "We believe the footprint Tortoise has already established in the energy infrastructure sector combined with the new Mariner affiliation will allow us to accelerate the growth of our fund and private account business."

The transaction helps propel Mariner further into the asset management business, a key pillar of its strategic vision. Mariner plans to accomplish this through additional product offerings, distribution capabilities and an expanded client base. "The Tortoise team brings significant depth, including closed-end fund and separate account development and management, portfolio management, client services and operational support, which will provide a well established platform for continued growth," said Marty Bicknell, Chairman and CEO of Mariner. "The recent closing of another fund, TPZ, underscores Tortoise's success at deepening its relationships with the investment banking community and growing its presence as a leading investor in the power and energy infrastructure sector."

Colchester Partners acted as financial advisor to Tortoise Capital Advisors in this transaction.
