LEAWOOD, Kan. — June 3, 2009 — Tortoise Capital Advisors, L.L.C. (Tortoise) the adviser of Tortoise Energy Infrastructure Corp., Tortoise Energy Capital Corp., Tortoise North American Energy Corp., and Tortoise Capital Resources Corp. (NYSE: TYG, TYY, TYN and TTO, respectively), today announced that senior management of Tortoise have entered into a definitive agreement to acquire, along with Mariner Holdings, LLC (Mariner), all of the ownership interests in Tortoise from Kansas City Equity Partners (KCEP) and affiliates of KCEP and Fountain Capital Management. Mariner will purchase a majority stake in Tortoise, with the intention to provide growth capital and resources, and serve as a complementary strategic partner in the asset management business.

Tortoise Managing Directors, Kevin Birzer, Zachary Hamel, Ken Malvey, Terry Matlack and David Schulte, will own approximately 35 percent of Tortoise and have agreed to employment contracts. Management of Tortoise, its Investment Committee and its funds will remain unchanged. Tortoise has also initiated an equity ownership plan in which four additional senior Tortoise employees will purchase equity.

"We are pleased to announce our partnership with Mariner, a well-capitalized firm in our home town," said Mr. Birzer. "This strategic combination of two entrepreneurial companies will provide a dynamic asset management team dedicated to providing clients with innovative products and industry-leading service."

The agreement 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. "Tortoise will strengthen our asset management capabilities, and fits our long-term strategy to create a world-class asset management business," said Marty Bicknell, Chairman and CEO of Mariner. "Over the past two years we have been methodically building our capabilities in the industry, and this agreement will take our combined assets under management to $3 billion, including both asset management and private wealth. 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."

The transaction is expected to close in the third quarter of 2009 and is subject to customary regulatory approvals and the approval by the stockholders of Tortoise's funds. Having approved the transaction, the independent Board of Directors of each of the Tortoise funds has recommended that the stockholders approve a new agreement with Tortoise.

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