LEAWOOD, Kan. – Oct. 09, 2008 – Tortoise Energy Infrastructure Corp. (NYSE: TYG) is providing an update for stockholders regarding its leverage coverage ratios due to broad based concerns over the recent decline in MLP values. Over the past several weeks we have witnessed one of the most volatile periods on Wall Street since the Great Depression, and the most volatile period ever experienced in the MLP sector. The market values of MLP equity securities, along with many other equity securities, have been experiencing substantial declines as a result of the ongoing financial crisis. From June 1 through October 8, 2008, the Wachovia MLP Total Return Index has declined by 39.3 percent. For the first three days of this week, the Index declined by 18.4 percent. We believe these declines have not been driven by fundamental weakness in the energy infrastructure sector; rather, we believe the unwinding of leverage and liquidity concerns in the broader financial market have driven a sell-off of MLPs.

TYG has used leverage to acquire MLPs consistent with our investment philosophy. The terms of TYG leverage are governed by regulatory and contractual asset coverage requirements that arise from the use of leverage. Under the Investment Company Act of 1940 (the 1940 Act), the company may not pay distributions to its common stockholders if it does not meet a 300 percent asset coverage ratio for notes and 200 percent asset coverage ratio for preferred shares after payment of the distribution, and it may not pay distributions on its preferred shares if the company fails to meet the 200 percent asset coverage ratio on its senior notes and preferred. Under the agreement with its bank lenders, if portfolio values decline such that it no longer meets the asset coverage ratios under the 1940 Act, TYG must repay a portion of its bank line until it meets the coverage requirement. Further, under the terms of its institutional senior notes and preferred shares, if the company fails to meet basic maintenance ratios as of any valuation date (generally Fridays) or fails to satisfy the 1940 Act asset coverage as of the last business day of any month, the company could be subject to mandatory redemption of the senior notes or preferred shares if such failure is not waived or cured. In some cases the company may be delayed in paying common stock or preferred share distributions until such coverage ratios can be met. The cure period is 10 business days for our auction rate senior notes and preferred shares and 30 days for our institutionally placed senior notes.

As of Friday, October 3, the company passed all of the tests on that valuation date. TYG's asset coverage ratio under the 1940 Act with respect to senior securities representing indebtedness was 319 percent, and its coverage ratio for preferred shares was 251 percent. Its senior notes and preferred shares basic maintenance coverage ratios (1.00 times required) were 1.39 times and 1.35 times, respectively. (For more information on calculation of coverage ratios, please refer to our most recent applicable prospectus.) However, as a result of the decline in portfolio company market values during this week, the company may not have sufficient coverage ratios to meet one or all of these tests at its next valuation date.

In response to these conditions, management will continue to work toward meeting asset coverage requirements on an ongoing basis; however, we will not be reporting on every valuation date. Several things could favorably impact asset coverage ratios, including: an increase in market values of portfolio holdings, issuance of additional equity (if the market and 1940 Act requirements permit), the sale of portfolio investments and repayment of leverage, or a delay in the payment of common or preferred distributions. The non-payment of common distributions would allow the company to de-lever and sell less of its investments at a time when we find the relative value for MLPs to be attractive. TYG paid its third quarter distribution on September 2, and normally declares its fourth quarter distribution during the second week in November.

While the current market conditions have been challenging, we maintain our long-term positive outlook for MLPs. These companies have generally continued to report growth in distributions to their investors, and, we believe are fundamentally strong, providing critical services to our country. We believe investors will be rewarded in the long run by continued investment in the MLP sector and TYG.
