This statement is filed on behalf of Karpus Management, Inc. d/b/a Karpus Investment Management ("KIM"), George W. Karpus, President, Director and Controlling Stockholder and Jo Ann Van Degriff, Partner Emeritus, 183 Sully's Trail, Pittsford, New York 14534.

On January 31, 2007 the Acting Director of the Securities Division of the Massachusetts Secretary of State (the Securities Division) filed a complaint against Bulldog Investors, Messrs. Goldstein, Samuels, Dakos and Das and certain related parties (the Bulldog Parties) alleging that they violated Massachusetts law by making information about certain unregistered investments available on the Bulldog Investors website and by sending material about such investments to an individual who requested it. On October 17, 2007 the Secretary issued a cease and desist order based on the same allegations and ordered that a fine be imposed on the Bulldog Parties of $25,000. On November 15, 2007 the Bulldog Parties filed an appeal of the Secretary's October 17, 2007 order in the Massachusetts Superior Court.

Letter to the Fund

Kevin S. McCarthy December 21, 2009 Chairman of the Board of Directors Kayne Anderson MLP Investment Company 717 Texas Avenue, Suite 3100 Houston, Texas 77002 Dear Mr. McCarthy:

After reading the press release issued on December 17, 2009 by Kayne Anderson MLP Investment Company ("KYN") stating that "the Company's Board of Directors is actively considering refinancing alternatives for its ARPS," Bulldog Investors purchased 81 shares of the ARPS.

As you know, at the 2010 annual meeting Karpus Management intends to nominate me for election as a director for a seat designated to be filled by solely by a vote of the preferred shareholders of KYN.

I am pleased that the board is actively considering financing alternatives for its ARPS. As you know, the ARPS were marketed to investors as an alternative to a money market fund. Unfortunately, that has turned out not to be the case and the preferred shareholders have gotten the short end of the stick. If I am elected to the board, my intention is to be a zealous advocate for all shareholders of KYN, and especially the preferred stockholders. In particular, I look forward to working with you and the other directors to explore options that would provide the preferred stockholders with an opportunity to realize the intrinsic value of their investment without any material adverse impact to the common shareholders.

Please contact me directly at 914-747-5262 if you would like to discuss this matter.

Very truly yours,


Phillip Goldstein
Principal
