Tortoise Energy Infrastructure Corp. Provides Update on Ratio Compliance

LEAWOOD, Kan. – Oct. 20, 2008 – Tortoise Energy Infrastructure Corp. (NYSE: TYG) today announced that as of the close of business on Oct. 17, 2008, the company was in compliance with all of its coverage covenants for its senior notes, preferred stock and bank debt. The company required no waivers from any lender and is not involved in any discussions to modify the terms of any of its agreements. On that date, the company's total assets were approximately $766 million. The company had approximately $6 million outstanding on its bank line of credit. While volatile market conditions continue, the company will report its NAV and asset coverage ratios on a weekly basis. The information will be published on its website at www.tortoiseadvisors.com each Monday, after market close, based on Friday's closing prices.

The company also announced that it is no longer requesting a rating on its auction rate preferred shares from Fitch Ratings, following confirmation that the company is in compliance with its basic maintenance covenant requirements. Lacking a viable auction rate market, there is no benefit in maintaining two rating agency relationships. Moody's Investors Service Inc. will be the sole rating agency for the company's preferred shares. Moody's maintains an Aa2 rating on the company's preferred shares.

"I am pleased with the improvement we have made with respect to our leverage coverage ratios," said Chief Financial Officer, Terry Matlack. "In addition, we continue to focus on our goal of providing an attractive current distribution for our stockholders and the steady growth of that distribution. We will continue to manage our leverage with that goal in mind."
