Tortoise North American Energy Corp. Announces Second Quarter Dividend Increase and Tax Credit

OVERLAND PARK, Kan. – May 12, 2006 - Tortoise North American Energy Corp. (NYSE: TYN), today declared the company's second quarterly dividend of $0.33 per share. The dividend will be distributed on June 1, 2006 to stockholders of record on May 23, 2006. The company also announced that it has accumulated a foreign source income tax credit for the income tax withheld during this quarter in Canada, of approximately $.04 per share.

"When our cash dividend is added to the availability of a tax credit, the pre-tax equivalent yield is 5.9 percent on our October 2005 IPO price of $25.00, and 6.8 percent on the May 11th market closing price of $21.85," said Tortoise Capital Advisors Managing Director, David Schulte. "The political stability of the North American energy complex has been increasingly important with recent geopolitical events. Our investments include the critical infrastructure in Canada and the U.S. connecting valuable on-continent reserve basins to end markets."

Based on current company financial information, this dividend is estimated to consist of 60 to 65 percent net income for book purposes, with the remainder consisting of return of capital. This is subject to change based upon completion of the company's fiscal year-end. For tax purposes, the character of the dividend and the amount of the tax credit will be determined at year-end and will be reported to stockholders at the beginning of 2007 on their Form 1099.
