Tortoise Energy Infrastructure Corp. Completes $150 Million Senior Notes Private Offering and Provides Notice of its Intention to Redeem Series D Auction Rate Senior Notes and a Portion of its Preferred Shares

OVERLAND PARK, Kan. - April 10, 2008 - Tortoise Energy Infrastructure Corp. (NYSE: TYG) today announced that it has completed a private offering of $150 million of Series E Senior Notes. The Notes are due in seven years and bear a fixed interest rate of 6.11 percent. The proceeds will be used to pay down its credit facility of approximately $45 million, redeem its Series D Senior Notes of $70 million, and redeem $15 million of its Series III Preferred Shares and $15 million of its Series IV Preferred Shares.

"We are pleased with our progress to date in refinancing auction rate securities, returning capital to those who invested in our senior notes and preferred shares. We believe this financing has attractive terms that will allow beneficial returns to common stockholders from the MLP investments that would not be available without leverage," said Chief Financial Officer, Terry Matlack.  "We intend to continue our efforts to secure alternative financing sources to allow redemption of all remaining Series III and Series IV Preferred Shares."
