Tortoise Energy Infrastructure Corp. Provides Notice of its Intention to Redeem All Remaining Series III and Series IV Auction Rate Preferred Shares



LEAWOOD, Kan. – June 24, 2008 – Tortoise Energy Infrastructure Corp. (NYSE: TYG) today announced that it intends to redeem the remaining $35 million of its Series III Auction Rate Preferred Shares on July 24, 2008 and the remaining $30 million of its Series IV Auction Rate Preferred Shares on July 23, 2008.

"These redemptions, along with our recently completed refinancing of Tortoise Notes, accomplishes either the elimination or extension of all of TYG's 28-day auction rate funding," said Chief Financial Officer, Terry Matlack. "We believe this benefits the company by reducing our immediate exposure to the volatility and uncertainty of the 28-day auction rate market while providing liquidity for our auction rate preferred stockholders. Going forward, we expect to continue to use leverage when it is expected to provide value creation to stockholders, and when we believe the all-in return from our investments will exceed our leverage costs."
