Tortoise Energy Infrastructure Corp. Announces Dividend Increase

OVERLAND PARK, Kan. - February 10, 2006 -- The Board of Directors of Tortoise Energy Infrastructure Corp. (NYSE: TYG) today declared the company's first quarter 2006 dividend of $0.48 per share, compared to $0.455 in the previous quarter and $0.44 in the same quarter of the prior year. The dividend will be distributed on March 1, 2006 to stockholders of record on February 21, 2006. This represents a 9.1 percent increase over the same quarter of the prior year, and a 5.5 percent increase over the distribution for the prior quarter.

"The investment objective set out in the IPO was growth with low risk," said Tortoise Capital Advisor's Managing Director David Schulte. "The solid fundamentals in the energy infrastructure sector of the U.S. economy led to impressive increases in distributions received from our investments. Further, risk was reduced since 100 percent of our variable rate leverage costs were swapped into long-term fixed interest rates. "

The company confirmed that this dividend is expected to be 100% return of capital for book purposes. This is subject to change based upon completion of the company's fiscal year. For tax purposes, the character of the dividend will be determined at year-end and will be reported to stockholders at the beginning of 2007 on their Form 1099.
