Tortoise Energy Infrastructure Corp. Provides Net Asset Value Update; Announces Company has Not Violated Coverage Covenants for its Senior Notes or Preferred Stock -- Will Host an Industry Update Call on Tuesday, October 14

LEAWOOD, Kan. - Oct. 13, 2008 - Tortoise Energy Infrastructure Corp. (NYSE: TYG) today announced that as of the close of business on Friday, Oct. 10, 2008, the company's total assets were approximately $686 million and its net asset value per share was $15.40. Friday's last sale price was $10.01 per share.

The company also announced that it has not violated any asset coverage covenants or basic maintenance covenants for its senior notes or preferred stock. According to the terms of its senior notes and preferred stock, the asset coverage covenants are calculated at the end of each month and the basic maintenance coverage covenants are calculated as of the end of each week. The company is not seeking any waiver or amendment at this time to the terms of its senior notes or preferred shares, which aggregate $280 million of the company's $323 million total leverage.

However, as of Friday, the company was not in compliance with its short-term borrowings covenant which requires that it consistently maintain a 300% asset coverage ratio, affecting its $43 million of unsecured short-term borrowings from its banks. The company is in discussions with its banks for a waiver under its bank loan agreement and expects to come to an acceptable agreement this week. The company currently has approximately $13 million of cash and expected cash from completed sales of securities.

Throughout this period of market unrest, management has maintained a dialogue with its lenders, all of whom are unsecured, to prudently manage its leverage and cash positions. Under the terms of its agreements with senior note holders and preferred stockholders, the company has nearly two months to remedy or receive a waiver on any coverage covenant breach, allowing for an orderly return to compliance. Terry Matlack, Chief Financial Officer of the company indicated, "We continue to monitor asset coverage ratios for the purposes of both the 1940 Act and the terms of our senior notes, preferred shares and bank debt. We are working diligently to preserve our ability to pay dividends to our common stockholders."

On Tuesday, Oct. 14, 2008 at 3:30 p.m. CDT, the company plans to host a teleconference to update its investors on the U.S. mid-stream energy infrastructure industry in which it invests. "In a period of tightening liquidity, we like investing in the providers of essential services" said Dave Schulte, President of the company. "Major customers of long haul natural gas pipelines include utilities and other companies that provide basic services. The ability of the MLPs in our portfolio to continue to pay increasing quarterly cash distributions is a direct result of the resiliency of their business operations and the investor friendly disciplines imbedded in their partnership agreements. Six of our MLP holdings have announced distributions as of Friday, and all have indicated distribution increases of between 1.5% to 3% over the prior quarter."

Set forth below is a summary of the company's unaudited and preliminary balance sheet as of Oct. 10, 2008, and a summary of its top 10 holdings.
