Automatic Dividend Reinvestment
and Cash Purchase Plan

The amended dividend reinvestment and cash purchase plan of Tortoise Energy Infrastructure Corp. became effective on April 1, 2007.

The automatic Dividend Reinvestment and Cash Purchase Plan (the "Plan") of Tortoise Energy Infrastructure Corporation (the "Company") allows participating common stockholders to receive distributions, including dividends, capital gains and return of capital in additional shares of the Company's common stock and allows participants to purchase additional shares of the Company's common stock through additional optional cash investments in amounts from a minimum of $100 to a maximum of $5,000 per month.

Automatic Dividend Reinvestment

If a stockholder’s shares are registered directly with the Company or with a brokerage firm that participates in the Plan, all distributions are automatically reinvested for stockholders by the Plan Agent, Computershare Trust Company, N.A. ("Computershare"), in additional shares of common stock of the Company (unless a stockholder is ineligible or elects otherwise). Stockholders who elect not to participate in the Plan will receive all distributions payable in cash paid by check mailed directly to the stockholder of record (or, if the shares are held in street or other nominee name, then to such nominee) by Computershare, as distribution paying agent. Distributions subject to tax (if any) are taxable whether or not shares are reinvested. Stockholders may elect not to participate in the Plan by sending written, telephone or Internet instructions to Computershare, as distribution paying agent, at the address set forth below. Participation in the Plan is completely voluntary and may be terminated or resumed at any time without penalty by giving notice in writing to the Plan Agent; such termination will be effective with respect to a particular distribution if notice is received prior to the record date for such distribution.

On the distribution payment date, if the net asset value per share of the common stock is equal to or less than the market price per share of common stock plus estimated brokerage commissions, the Company will issue additional shares of common stock to the Plan Agent for each participant's account. The number of shares to be credited to the participant's account will be determined by dividing the dollar amount of the distribution by the greater of (i) the asset value per share of common stock on the payment date, or (ii) 95 percent of the market price per share of common stock on the payment date. If, on the payment date, the net asset value per share of common stock exceeds the market price plus estimated brokerage commissions, the Plan Agent will invest the distribution amount in shares acquired in open-market purchases as soon as practicable, but not later than 30 days following the payment date. The weighted average price (including brokerage commissions) of all common stock purchased by the Plan Agent as Plan Agent will be the price per share of common stock allocable to each participant.

There are no brokerage charges with respect to shares issued directly by the Company as a result of distributions payable either in shares or in cash. However, each participant will pay a pro rata share of brokerage commissions incurred with respect to the Plan Agent’s open-market purchases in connection with the reinvestment of distributions. If a participant elects to have the Plan Agent sell part or all of his or her common stock and remit the proceeds, such participant will be charged a transaction fee plus his or her pro rata share of brokerage commissions on the shares sold.

Cash Purchase Option

The Plan allows registered stockholders to make optional cash investments, in accordance with the Plan, on a monthly basis. Any single investment pursuant to the cash purchase option under the Plan must be in an amount of at least $100 and may not exceed $5,000 per month unless a request for waiver has been granted. A request for waiver should be directed to the Company at 1-866-362-9331, and the Company has the sole discretion to grant any requested waiver. Optional cash investments may be delivered to Computershare by personal check, by automatic or electronic bank account transfer or by online access at www.computershare.com. Participants should send checks drawn on a U.S. bank, made payable in U.S. dollars to Computershare -Tortoise Energy Infrastructure Corporation and mailed to Computershare Trust Company, N.A., P.O. Box 6006, Carol Stream, IL 60197-6006. Computershare will not accept cash, traveler's checks, money orders, third party checks or checks drawn on non-U.S. banks. The Company reserves the right to reject any purchase order. Stockholders who hold shares in street or other nominee name who want to participate in optional cash investments should contact their broker, bank or other nominee and follow their instructions.

There is no obligation to make an optional cash investment at any time, and the amount of such investments may vary from time to time. In order to participate in the cash investment option in any given month, Computershare must receive from the participant any optional cash investment no later than two business days prior to the monthly investment date (the "payment date") for purchase of common shares on the next succeeding purchase date. All optional cash investments received on or prior to the payment date will be applied by Computershare to purchase shares on the next succeeding purchase date. Participants may obtain a schedule of relevant dates on our Web site or by calling 1-866-362-9331.

Common stock purchased pursuant to this option will be issued by the Company when the Company's shares are trading at a premium to net asset value. If the Company's common stock is trading at a discount to net asset value, shares of common stock will be purchased in the open market by Computershare as described above with respect to reinvestment of distributions.
