THIS AMENDED AND RESTATED INVESTMENT MANAGEMENT AGREEMENT (this “Agreement”) is made as of the 12^th day of December, 2006, by and between Kayne Anderson MLP Investment Company, a Maryland corporation (hereinafter called the “Company”), and Kayne Anderson Capital Advisors, L.P., a California limited partnership (hereinafter called the “Manager”).

WITNESSETH:

WHEREAS, the Company is a non-diversified, closed-end management investment company, registered as such under the Investment Company Act of 1940, as amended (the “1940 Act”);

WHEREAS, the Manager is registered as an investment adviser under the Investment Advisers Act of 1940, as amended, and is engaged in the business of supplying investment advice, investment management and administrative services, as an independent contractor;

WHEREAS, the Company desires to retain the Manager to render advice and services to the Company pursuant to the terms and provisions of this Agreement, and the Manager is interested in furnishing said advice and services; and

WHEREAS, the Company and the Manager previously entered into that certain Investment Management Agreement dated as of September 27, 2004 (the “Original Agreement”) and each now desires that the Original Agreement be replaced and superseded in its entirety by this Agreement;

NOW, THEREFORE, in consideration of the covenants and the mutual promises hereinafter set forth, the parties hereto, intending to be legally bound hereby, mutually agree as follows:

1. Appointment of Manager. The Company hereby employs the Manager and the Manager hereby accepts such employment, to render investment advice and management services with respect to the assets of the Company for the period and on the terms set forth in this Agreement, subject to the supervision and direction of the Company’s Board of Directors (“the Board”).

2. Duties of Manager.

(a) General Duties. The Manager shall act as investment manager to the Company and shall supervise investments of the Company in accordance with the investment objectives, programs and restrictions of the Company as provided in the Company’s governing documents, including, without limitation, the Company’s Charter and Bylaws, or otherwise and such other limitations as the Board may impose from time to time in writing to the Manager. Without limiting the generality of the foregoing, the Manager shall: (i) furnish the Company with advice and recommendations with respect to the investment of the Company’s assets and

the purchase and sale of portfolio securities for the Company, including the taking of such other steps as may be necessary to implement such advice and recommendations; (ii) furnish the Company with reports, statements and other data on securities, economic conditions and other pertinent subjects which the Board may reasonably request; (iii) manage the investments of the Company, subject to the ultimate supervision and direction of the Board; (iv) provide persons satisfactory to the Board to act as officers and employees of the Company (such officers and employees, as well as certain directors, may be directors, officers, partners, or employees of the Manager or its affiliates); and (v) render to the Board such periodic and special reports with respect to the Company’s investment activities as the Board may reasonably request.

(b) Brokerage. The Manager shall place orders for the purchase and sale of securities either directly with the issuer or with a broker or dealer selected by the Manager. In placing the Company’s securities trades, it is recognized that the Manager will give primary consideration to securing the most favorable price and efficient execution, so that the Company’s total cost or proceeds in each transaction will be the most favorable under all the circumstances. Within the framework of this policy, the Manager may consider the financial responsibility, research and investment information, and other services provided by brokers or dealers who may effect or be a party to any such transaction or other transactions to which other clients of the Manager may be a party.

It is also understood that it is desirable for the Company that the Manager have access to investment and market research and securities and economic analyses provided by brokers and others. It is also understood that brokers providing such services may execute brokerage transactions at a higher cost to the Company than might result from the allocation of brokerage to other brokers on the basis of seeking the most favorable price and efficient execution. Therefore, the purchase and sale of securities for the Company may be made with brokers who provide such research and analysis, subject to review by the Board from time to time with respect to the extent and continuation of this practice to determine whether the Company benefits, directly or indirectly, from such practice. It is understood by both parties that the Manager may select broker-dealers for the execution of the Company’s portfolio transactions who provide research and analysis as the Manager may lawfully and appropriately use in its investment management and advisory capacities, whether or not such research and analysis may also be useful to the Manager in connection with its services to other clients.

On occasions when the Manager deems the purchase or sale of a security to be in the best interest of the Company as well as of other clients, the Manager, to the extent permitted by applicable laws and regulations, may aggregate the securities to be so purchased or sold in order to obtain the most favorable price or lower brokerage commissions and the most efficient execution. In such event, allocation of the securities so purchased or sold, as well as the expenses incurred in the transaction, will be made by the Manager in the manner it considers to be the most equitable and consistent with its fiduciary obligations to the Company and to such other clients.

(c) Administrative Services. The Manager shall oversee the administration of the Company’s business and affairs although the provision of administrative services, to the extent not covered by subparagraphs (a) or (b) above, is not the obligation of the Manager under this Agreement. Notwithstanding any other provisions of this Agreement, the Manager shall be entitled to reimbursement from the Company for all or a portion of the reasonable costs and expenses, including salary, associated with the provision by Manager of personnel to render administrative services to the Company.

3. Best Efforts and Judgment. The Manager shall use its best judgment and efforts in rendering the advice and services to the Company as contemplated by this Agreement.

4. Independent Contractor. The Manager shall, for all purposes herein, be deemed to be an independent contractor, and shall, unless otherwise expressly provided and authorized to do so, have no authority to act for or represent the Company in any way, or in any way be deemed an agent for the Company. It is expressly understood and agreed that the services to be rendered by the Manager to the Company under the provisions of this Agreement are not to be deemed exclusive, and the Manager shall be free to render similar or different services to others so long as its ability to render the services provided for in this Agreement shall not be impaired thereby.

5. Manager’s Personnel. The Manager shall, at its own expense, maintain such staff and employ or retain such personnel and consult with such other persons as it shall from time to time determine to be necessary to the performance of its obligations under this Agreement. Without limiting the generality of the foregoing, the staff and personnel of the Manager shall be deemed to include persons employed or retained by the Manager to furnish statistical information, research, and other factual information, advice regarding economic factors and trends, information with respect to technical and scientific developments, and such other information, advice and assistance as the Manager or the Board may desire and reasonably request.

6. Reports by Company to Manager. The Company will from time to time furnish to the Manager detailed statements of its investments and assets, and information as to its investment objective and needs, and will make available to the Manager such financial reports, proxy statements, legal and other information relating to the Company’s investments as may be in its possession or available to it, together with such other information as the Manager may reasonably request.

8. Investment Advisory and Management Fee.

The Manager may not request or receive reimbursement for prior reductions or reimbursements before payment of the Company’s operating expenses for the current year and cannot cause the Company to exceed any more restrictive limitation to which the Manager has agreed in making such reimbursement.

(e) The Manager may agree not to require payment of any portion of the compensation or reimbursement of expenses otherwise due to it pursuant to this Agreement prior to the time such compensation or reimbursement has accrued as a liability of the Company. Any such agreement shall be applicable only with respect to the specific items covered thereby and shall not constitute an agreement not to require payment of any future compensation or reimbursement due to the Manager hereunder.

9. Conflicts with Company’s Governing Documents and Applicable Laws. Nothing herein contained shall be deemed to require the Company to take any action contrary to the Company’s Charter, Bylaws, or any applicable statute or regulation, or to relieve or deprive the Board of its responsibility for and control of the conduct of the affairs of the Company.
