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

Re:	Auction Rate Preferred Securities - Director Conflict of Interest
Board Members:

I write this letter to the Board to address a conflict of interest that exists and was created when the auctions for closed-end fund preferred shares began to fail in February of 2008. As you know, prior to the failure of these auctions, preferred shareholders could participate in the auction process and receive par value for their investment. Now that the auction process has frozen, preferred shareholders must rely upon their Board, more than ever, to address this matter, return their capital and protect their interests.

This additional responsibility of the Board has, in our view, resulted in a significant conflict of interest for directors/trustees who own common shares of the fund(s) that they oversee. Since common shareholders are benefiting from the low interest rate paid on the preferred shares, their interests are in direct opposition with those of preferred owners demanding the return of their capital. We feel that this is the exact type of protection that the Investment Company Act of 1940 intended to protect by affording preferred shareholders the ability to elect at least two directors/trustees.

    Consequently, Karpus Investment Management urges the Board to do the following:

    1) Any Director/Trustee owning common shares of a fund that they oversee should recuse themselves from any decisions regarding preferred shareholders and;

    2) Boards should be aggressively renegotiating and/or putting out for bid their auction agent contracts.

As I am sure that the Board is aware, the Auction Agency Agreement generally allows for the reduction of fees and the right to terminate the agreement. A few fund families, such as BlackRock, have already taken actions to reduce the auction agent's fee. We expect all Boards to do so and, due to the conflict of interest described above, we feel that preferred shareholder elected directors/trustees who own common shares and who do not advocate for renegotiations lowering auction agent fees are violating their fiduciary duties, as well as the protections that were established to protect preferred shareholders under the Investment Company Act of 1940.

I would appreciate your immediate response to our concerns over the conflict of interests between preferred and common shareholders and your commitment to, or efforts made, to reduce your fund's auction agent fee. Please feel free to contact me directly at (585) 586-4680 (ext. 235). Thank you for your time and consideration.

Sincerely,


Cody B. Bartlett Jr., CFA
Managing Director of Investments
