LETTER TO STOCKHOLDERS

January 23, 2006

Dear Fellow Stockholders:

      It has been an exciting and active year for the Company and we are pleased with the Company’s performance during the twelve months ended November 30, 2005. We continue to believe that the MLP sector will provide attractive risk adjusted returns and that we have assembled a very experienced team to take advantage of the opportunities we see in this sector.

      One of the measures employed by us to evaluate our performance is the change in our Adjusted Net Asset Value per share, which is equal to the Net Assets per common share plus cumulative dividends paid per common share. During the year ended November 30, 2005 (“fiscal 2005”), our Adjusted Net Asset Value per share increased by $2.655, or 11.1%, from $23.91 as of November 30, 2004 to $26.565 as of November 30, 2005. During this same period, we calculated that the market-weighted composite of 41 MLPs (the “MLP Composite”) had a total return (total return is defined as unit price appreciation plus distributions) of 10.5%.

      We were very active on both the investing and capital raising fronts, having made net investments of $780 million and having raised new capital of $416 million. The majority of these investments were made through the completion of 11 private transactions for a total of $728 million. As a result of our capital raising activity, as well as the performance of our investments, our long-term investments have increased to $1.26 billion at November 30, 2005 compared to $380 million at November 30, 2004. Approximately 96% of these long-term investments were securities of MLPs or MLP Affiliates.

Market Overview

      The MLP sector during calendar 2005 once again exhibited strong performance, especially from an operational perspective. Based on public filings, we believe the sector broke previous records for equity capital raised, acquisitions completed and capital spent on internal growth projects. Largely as a result of these factors, the MLP Composite increased dividends by 9.5% during calendar 2005. The strongest performing sectors in terms of dividend growth were the Coal MLP sector and the Pipeline MLP sector, which increased dividends by an average of 21.0% and 9.3%, respectively.

      The stock market performance of the MLP group was mixed during the year. The MLP Composite performed extremely well during the first seven months of the calendar year, then gave back some of the gains in the last five months of the year. From January 1, 2005 through July 31, 2005, the MLP Composite generated a total return of approximately 16.3%. From August 1, 2005 through December 31, 2005, the MLP Composite generated a total return of negative 9.0%. We believe that much of the declining performance during the last five months of calendar 2005 was due to investor concerns about rising short term interest rates, as well as a very heavy new issuance calendar. During calendar year 2005, short term interest rates (1-month LIBOR) increased from 2.40% to 4.39%. Based on public filings, total public equity capital raised from August 1, 2005 through December 31, 2005 was $3.1 billion, which is slightly less than the total equity capital raised in the public markets during all of calendar 2004.

      Total return for the MLP composite was 5.9% during calendar 2005, as negative stock price performance offset increasing cash distributions. For comparative purposes, our Adjusted Net Asset Value per share increased by 8.7% during calendar 2005.

      Shipping and Other MLPs (five MLPs which represent only 4% of total MLP equity capitalization) was the strongest performing sub-sector, generating total returns of approximately 9.1% during calendar 2005. The Pipeline MLP sub-sector also had a strong performance, with total returns of 6.6%. In the pipeline sector, distributions increased by an average of 9.3%, which was offset by an increase in the average yield from 6.1% at January 1, 2005 to 6.8% at December 31, 2005.

KAYNE ANDERSON MLP INVESTMENT COMPANY

LETTER TO STOCKHOLDERS — (CONTINUED)

      The Propane MLP sub-sector generated total returns of negative 0.4% during calendar 2005. This performance was largely due to a substantial increase in the average yield for this sub-sector, as investors worried whether high commodity prices would lead to widespread conservation and lower propane consumption.

      The Coal MLP sub-sector generated total returns of 3.1% during the period, as substantial increases in distributions (average increase of 21.0%) were offset by substantially higher yields as most of the distribution increases that investors expected were realized in calendar 2005.

      There were nine MLP IPOs completed during calendar 2005, raising almost $1.4 billion, including the IPO of two general partners. These IPOs ended the year at prices that averaged 28% above their IPO price.

2006 Outlook

      We expect a number of factors to impact the performance of MLPs during 2006. We believe that significant investment challenges exist, while opportunities remain excellent. As was the case in 2005, we believe that stock selection will be an important key to long-term investment success.

      We believe that the acquisition prospects for MLPs remain quite good, with many packages of midstream assets on the market or available for sale that fit well in the portfolios of many MLPs. While we are concerned with the steady increase in acquisition multiples, we expect that acquisitions will continue to be accretive. Furthermore, there has been a significant increase in the investment opportunities to expand existing assets, which typically have much higher projected returns (or lower multiples) than acquisitions. As a result, the blended cost of growth (acquisitions and internal growth) remains attractive relative to prior years.

      Based largely on internal growth prospects, and to a lesser extent acquisitions, we believe that the MLP universe will continue to grow distributions. Wall Street research is projecting distribution growth rates of 6% to 8% for calendar year 2006.

      Another investment challenge for us is to monitor the commodity price exposure of the various MLPs. Over the last several years, the commodity price exposure of the sector, both direct and indirect, has increased. We believe there is an investment opportunity for us as the market valuation of individual MLPs does not always reflect the different levels of commodity price exposure.

      At the beginning of the year, MLP valuations, as measured by the spread between MLP yields and 10-year U.S. Treasury rates, were higher (spreads lower) than the five-year average. At December 31, 2005, valuations were in-line (spreads approximately equal) with the five-year average, reflecting the increase in average yields compared to a 10-year U.S. Treasury that was relatively flat compared to the beginning of the year.

      We believe that MLPs, as a group, continue to offer above-average investment appeal with lower-than-average market risk. Current yield plus expected growth appears to well exceed the 8% to 10% long-term total return expected by many market strategists for the stock market. As important, most MLPs provide stable and predictable cash flow from “hard assets” and, by most measures, provide lower risk than other equity investments. We remain confident that the long-term investment case for MLPs is very strong, and that our selection process will provide our stockholders with the opportunity for superior returns.

Fiscal 2005 Financial Highlights

      Because the MLPs that we own in our portfolio are treated as partnerships for federal income tax purposes, we only reflect 10% of the cash dividends received from our MLP securities as investment income. The remaining 90% of the cash distributions are treated as a return of capital, which increases our realized and unrealized gains by lowering our cost basis. As a result, we expect on an ongoing basis to report a net investment loss. During fiscal year 2005, our net investment loss was $5.9 million. This consisted of net

2

LETTER TO STOCKHOLDERS — (CONCLUDED)

dividends and distributions from MLPs and other Midstream Energy Companies of $6.2 million after the deduction of $48.8 million of cash dividends and distributions received by us that were treated as a return of capital. Income on repurchase agreements and fixed income investments was $4.4 million. Expenses were $20.2 million, including $10.2 million of investment management fees and $6.9 million of interest expense. Investment management fees were equal to an annual rate of 0.87% of total assets (1.17% of net assets applicable to common stockholders), and were based on our performance relative to our benchmark, which is based on the Standard and Poor’s Midcap Utility Index. Results include a current income tax benefit of $3.7 million.

      Net realized gains during fiscal year 2005 were $13.6 million, consisting of realized gains on investments of $23.2 million and securities sold short of $0.6 million, offset by a loss of $0.2 million on options, $1.5 million of payments pursuant to interest rate swap contracts and $8.5 million of current income tax expense.

      Net change in unrealized gains during fiscal year 2005 was $81.9 million, consisting of unrealized gains on investments and options of $129.0 million and $0.6 million, respectively, an increase in the mark-to-market value of the interest rate swap contracts of $3.4 million and a current income tax benefit of $1.1 million. These gains were offset by $52.2 million of deferred income tax expense.

      Net increase in net assets resulting from operations was $89.6 million before dividends to the preferred stockholders of $1.7 million. Net assets applicable to common stockholders increased from $23.91 per common share to $25.07 per common share.

      During fiscal 2005, we paid four quarterly dividends to our common stockholders, which totaled $1.495 per share (approximately 91% of this amount was classified as a return of capital and the remaining 9% was classified as dividend income). Included in this total is our dividend of $0.25 per share paid in January 2005. This dividend was a partial dividend reflecting our two months of operations during the fourth quarter of fiscal 2004 and reflects a full quarter dividend rate of $0.375 per share. During January 2006, we paid a quarterly dividend of $0.425 per share (indicative annual rate of $1.70 per share). This quarterly dividend rate was 13% higher than our initial quarterly rate of $0.375 and represented the fourth increase in our dividend rate since inception. Management intends to continue paying quarterly dividends and expects to increase its dividends to the extent permitted by increases in the dividends and distributions from its portfolio.

      We look forward to continuing to execute on our business plan of achieving high after-tax total returns by investing in MLPs and Other Midstream Companies. We invite you to visit our website at www.kaynemlp.com for the latest updates.

Sincerely,

Kevin McCarthy

Chairman of the Board of Directors,

President, and Chief Executive Officer

MANAGEMENT DISCUSSION

FOR THE FISCAL YEAR ENDED NOVEMBER 30, 2005

      This discussion contains forward looking statements and good faith estimates. The reader is referred to the disclosure on such matters at the beginning of this annual report.

Overview

      Kayne Anderson MLP Investment Company (the “Company”) is a non-diversified, closed-end investment company. The Company’s investment objective is to obtain a high after-tax total return by investing at least 85% of its total assets in energy-related master limited partnerships (“MLPs”) and their affiliates, and in other companies that, as their principal business, operate assets used in the gathering, transporting, processing, storing, refining, distributing, mining or marketing of natural gas, natural gas liquids, crude oil, refined petroleum products or coal (collectively with MLPs, “Midstream Energy Companies”).

      The Company’s portfolio investments are principally comprised of equity securities issued by MLPs. Generally, the Company invests in equity securities of (i) energy-related MLPs, (ii) owners of such interests in MLPs (“MLP Affiliates”), and (iii) other Midstream Energy Companies. The Company may, from time to time, invest in debt securities of MLPs and other Midstream Energy Companies. At November 30, 2005, the Company’s long-term investments were as follows:

Long-term Investments (at 11/30/2005)

		Amount		Percentage
Category		($ in 000s)		of Total
Equity
	MLP	$	1,191,262		94.4	%
	MLP Affiliate		14,825		1.2
	Other Midstream Energy		55,549		4.4
Fixed Income			488		0.0
Total		$	1,262,124		100.0	%

      As a limited partner in the MLPs, the Company reports its allocable share of MLP’s taxable income in computing its own taxable income. During the year ended November 30, 2005 (“fiscal year 2005”), the Company estimated that taxable income associated with its ownership in MLPs was equal to 10% of the distributions received from such MLPs. As a result, the Company estimated that 90% of the MLP distributions will be treated as a return of capital for tax purposes. For financial reporting purposes, the Company reflects its MLP distributions net of the return of capital portion. As a result, only 10% of the cash distributions from MLPs received during fiscal year 2005 are included in investment income. The remaining 90% of distributions from MLPs are reflected as a reduction in the cost basis of the Company’s portfolio securities, which has the effect of increasing realized and unrealized gains by that same amount.

Performance Review

      One of the measures employed by the Company to evaluate total return is Adjusted Net Asset Value per share, which is equal to the Net Assets per common share plus cumulative dividends paid on the Company’s common stock. During fiscal year 2005, the Company’s Adjusted Net Asset Value per share increased by $2.655, or 11.1%, from $23.91 as of November 30, 2004 to $26.565 as of November 30, 2005. For comparative purposes, the total return of the MLP Composite (total return is defined as unit price appreciation plus distributions) was 10.5% over the same time period.

      The Company paid four quarterly dividends to its common stockholders during fiscal year 2005, totalling $1.495 per share. Included in this total is the Company’s dividend of $0.25 per share paid during January 2005.

KAYNE ANDERSON MLP INVESTMENT COMPANY

MANAGEMENT DISCUSSION — (CONTINUED)

This dividend was a partial dividend reflecting the Company’s two months of operations during the fourth quarter of fiscal 2004 and reflects a full quarter dividend rate of $0.375 per share. During January 2006, the Company paid a quarterly dividend of $0.425 per share (indicative annual rate of $1.70 per share). This quarterly dividend rate was 13% higher than the Company’s initial quarterly rate of $0.375 and represented the fourth increase in the Company’s dividend rate since inception. Management intends to continue paying quarterly dividends and expects to increase its dividends to the extent permitted by increases in the dividends and distributions from its portfolio. Future dividend increases are subject to, among other things, the operating performance of the Company, realized gains and unrealized gains.

Financial Review

      During fiscal year 2005, the Company had a net increase in net assets resulting from operations of $89.6 million. The components of this increase are (i) a net investment loss of $5.9 million ($9.6 million before taxes), (ii) net realized gains of $13.6 million ($22.1 million before taxes) and (iii) net change in unrealized gains of $81.9 million ($132.9 million before taxes).

      The Company incurred a net investment loss (before taxes) of $9.6 million during fiscal year 2005. This consisted of net dividends and distributions from MLPs and other Midstream Energy Companies of $6.2 million, which was after the deduction of $48.8 million of cash dividends and distributions received by the Company that were treated as a return of capital. Income on repurchase agreements and fixed income investments was $4.4 million. Expenses were $20.2 million, including $10.2 million of investment management fees and $6.9 million of interest expense. Investment management fees were equal to an annual rate of 0.87% of total assets (1.17% of net assets applicable to common stockholders) and were based on the performance of the Company relative to its benchmark, which is based on the Standard and Poor’s Midcap Utility Index.

      Net realized gains (before taxes) during fiscal year 2005 were $22.1 million, consisting of realized gains on investments of $23.2 million and securities sold short of $0.6 million, offset by a loss of $0.2 million on options and $1.5 million of payments pursuant to interest rate swap contracts. In order to partially hedge itself against rising interest rates, the Company has entered into interest rate swap contracts with a notional value of $250 million. Payments made pursuant to those swap contracts are not reflected in interest expense, but are reflected as realized losses.

      Net change in unrealized gains (before taxes) during fiscal year 2005 was $132.9 million, consisting of unrealized gains on investments and options of $129.0 million and $0.6 million, respectively. Net change in unrealized gains also included an increase in the mark-to-market value of the interest rate swap contracts of $3.4 million.

      The Company is taxed as a corporation for federal and state income tax purposes. As a result, the Company records a current income tax expense/(benefit) based on the investment income/(loss) and realized gains. Similarly, the Company records a deferred income tax expense based on the unrealized gains, which are equal to the difference between the current market value of its assets and liabilities compared to the tax basis of those assets and liabilities. During fiscal year 2005, the Company recorded a current income tax benefit attributable to its investment income of $3.7 million, a current income tax expense of $8.5 million attributable to its realized gains and a net tax expense of $51.0 million attributable to it unrealized gains (comprised of a current income tax benefit of $1.2 million and a deferred income tax expense of $52.2 million). The Company’s taxes were computed based on an effective tax rate of approximately 38.5% for fiscal year 2005 as compared to an effective tax rate of 40.0% for the period ended November 30, 2004.

Capital Raising Transactions

      The Company completed several capital raising transactions during fiscal year 2005, raising $416 million of gross proceeds. The Company was able to invest these proceeds in a manner consistent with its investment

KAYNE ANDERSON MLP INVESTMENT COMPANY

MANAGEMENT DISCUSSION — (CONCLUDED)

strategies and management believes that these investments have enhanced the total return of the Company’s common stockholders.

      On March 28, 2005, the Company issued three series of auction rate senior notes, each with a maturity of 40 years, having an aggregate principal amount of $260 million. On April 12, 2005, the Company issued 3,000 shares of Series D auction rate preferred stock for gross proceeds of $75 million. The interest rate and dividend rate on these securities are reset every 7 or 28 days, depending upon the series. At November 30, 2005, the interest rates for the Series A, Series B, and Series C senior notes were 4.21%, 4.18% and 4.24%, respectively, and the dividend rate for the Series D preferred stock was 4.35%.

      In order to partially hedge itself from a floating interest expense on its leverage, the Company has entered into nine interest rate swap contracts on a notional amount of $250 million with a weighted average fixed rate of 4.42% and weighted average duration of 4.7 years (as of November 30, 2005). In each of these contracts, the Company pays a fixed rate of interest and receives a floating rate of interest based on the London Interbank Offered Rate (LIBOR).

      On October 12, 2005 the Company issued 3,000,000 shares of common stock in a secondary public offering at $27.00 per share, raising an additional $81 million of gross proceeds.

      During fiscal year 2005, the Company completed eleven private transactions investing, in aggregate, $728 million. As of November 30, 2005, the Company held investments in freely tradable (or “public”) equity and debt securities valued at $914 million and held investments in restricted (or “private”) equity securities valued at $348 million. The total value at year-end of the Company’s long-term investments was $1.26 billion.

Recent Events

      On December 14, 2005, the Company announced the successful completion of its $60 million offering of Series E auction rate senior notes. The initial interest rate on the Series E senior notes was 4.05%, with subsequent interest rates determined at weekly auctions. The Company intends to invest the net proceeds from this offering in accordance with the Company’s investment policies as soon as practicable. Management believes that substantially all of the net proceeds will be invested within three months of the offering.

      On January 12, 2006, the Company paid a dividend to its common stockholders in the amount of $0.425 per share, for a total of $15.8 million. Pursuant to the Company’s dividend reinvestment plan, $6.6 million of this amount was reinvested into the Company for 0.3 million shares of common stock.

KAYNE ANDERSON MLP INVESTMENT COMPANY

NOTES TO FINANCIAL STATEMENTS

NOVEMBER 30, 2005

(amounts in 000’s, except share and per share amounts)

1. Organization

      Kayne Anderson MLP Investment Company (the “Company”) was organized as a Maryland corporation on June 4, 2004, and is a non-diversified closed-end management investment company registered under the Investment Company Act of 1940, as amended (the “1940 Act”). The Company’s investment objective is to obtain a high after-tax total return by investing at least 85% of its net assets plus any borrowings (“total assets”) in energy-related master limited partnerships and their affiliates (collectively, “MLPs”), and in other companies that, as their principal business, operate assets used in the gathering, transporting, processing, storing, refining, distributing, mining or marketing of natural gas, natural gas liquids (including propane), crude oil, refined petroleum products or coal (collectively with MLPs, “Midstream Energy Companies”). The Company commenced operations on September 28, 2004. The Company’s shares of common stock are listed on the New York Stock Exchange, Inc. (“NYSE”) under the symbol “KYN”.

2. Significant Accounting Policies

      A.     Use of Estimates — The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”) requires management to make estimates and assumptions that affect the reported amount of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the period. Actual results could differ materially from those estimates.

      B.     Calculation of Net Asset Value — The Fund determines its net asset value as of the close of regular session trading on the NYSE (normally 4:00 p.m. Eastern time) no less frequently than the last business day of each month, and makes its net asset value available for publication monthly. Net asset value is computed by dividing the value of the Company’s assets (including accrued interest and dividends), less all of its liabilities (including accrued expenses, dividends payable, current and deferred and other accrued income taxes, and any borrowings) and the liquidation value of any outstanding preferred stock, by the total number of common shares outstanding.

      C.     Investment Valuation — Readily marketable portfolio securities listed on any exchange other than the NASDAQ Stock Market, Inc. (“NASDAQ”) are valued, except as indicated below, at the last sale price on the business day as of which such value is being determined. If there has been no sale on such day, the securities are valued at the mean of the most recent bid and asked prices on such day, except for short sales and call options written, for which the last quoted asked price is used. Securities admitted to trade on the NASDAQ are valued at the NASDAQ official closing price. Portfolio securities traded on more than one securities exchange are valued at the last sale price on the business day as of which such value is being determined at the close of the exchange representing the principal market for such securities.

      Equity securities traded in the over-the-counter market, but excluding securities admitted to trading on the NASDAQ, are valued at the closing bid prices. Fixed income securities with a remaining maturity of 60 days or more are valued by the Company using a pricing service. Fixed income securities maturing within 60 days will be valued on an amortized cost basis.

      The Company holds securities that are privately issued or otherwise restricted as to resale. For these securities, as well as any other portfolio security held by the Company for which reliable market quotations are not readily available, valuations are determined in a manner that most fairly reflects fair value of the security

16

KAYNE ANDERSON MLP INVESTMENT COMPANY

NOTES TO FINANCIAL STATEMENTS — (CONTINUED)

on the valuation date. Unless otherwise determined by the Board of Directors, the following valuation process is used for such securities:

•  Investment Team Valuation. The applicable investments are initially valued by Kayne Anderson Capital Advisors, L.P.’s (“Kayne Anderson” or the “Advisor”) investment professionals responsible for the portfolio investments;

•  Investment Team Valuation Documentation. Preliminary valuation conclusions are documented and discussed with senior management of Kayne Anderson. Such valuations generally are submitted to the Valuation Committee (a committee of the Company’s Board of Directors) or the Board of Directors on a monthly basis, and stand for intervening periods of time.

•  Valuation Committee. The Valuation Committee meets on or about the end of each month to consider new valuations presented by Kayne Anderson, if any, which were made in accordance with the Valuation Procedures in such month. Between meetings of the Valuation Committee, a senior officer of Kayne Anderson is authorized to make valuation determinations. The Valuation Committee’s valuations stand for intervening periods of time unless the Valuation Committee meets again at the request of Kayne Anderson, the Board of Directors, or the Committee itself. All valuation determinations of the Valuation Committee are subject to ratification by the Board at its next regular meeting.

•  Valuation Firm. No less than quarterly, a third-party valuation firm engaged by the Board of Directors reviews the valuation methodologies and calculations employed for these securities.

•  Board of Directors Determination. The Board of Directors meets quarterly to consider the valuations provided by Kayne Anderson and the Valuation Committee, if applicable, and ratify valuations for the applicable securities. The Board of Directors considers the report provided by the third-party valuation firm in reviewing and determining in good faith the fair value of the applicable portfolio securities.

      Unless otherwise determined by the Board of Directors, securities that are convertible into or otherwise will become publicly traded (e.g., through subsequent registration or expiration of a restriction on trading) are valued through the process described above, using a valuation based on the market value of the publicly traded security less a discount. The discount is initially equal in amount to the discount negotiated at the time the purchase price is agreed to. To the extent that such securities are convertible or otherwise become publicly traded within a time frame that may be reasonably determined, Kayne Anderson may determine an amortization schedule for the discount in accordance with a methodology approved by the Valuation Committee.

      At November 30, 2005, the Company held 37.3% of its net assets (26.1% of total assets) applicable to common stockholders in securities valued at fair value as determined pursuant to procedures adopted by the Board of Directors, with an aggregate cost of $325,781 and fair value of $347,669. Although these securities may be resold in privately negotiated transactions (subject to certain lock-up restrictions), these values may differ from the values that would have been used had a ready market for these securities existed, and the differences could be material.

      Any option transaction that the Company enters into may, depending on the applicable market environment have no value or a positive/negative value. Exchange traded options and futures contracts are valued at the closing price in the market where such contracts are principally traded.

      D. Repurchase Agreements — The Company has agreed to purchase securities from financial institutions subject to the seller’s agreement to repurchase them at an agreed-upon time and price (“repurchase agreements”). The financial institutions with whom the Company enters into repurchase agreements are banks and broker/ dealers which Kayne Anderson considers creditworthy. The seller under a repurchase agreement is required to maintain the value of the securities as collateral, subject to the agreement, at not less than the repurchase price plus accrued interest. Kayne Anderson monitors daily the mark-to-market of the

17

KAYNE ANDERSON MLP INVESTMENT COMPANY

NOTES TO FINANCIAL STATEMENTS — (CONTINUED)

value of the collateral, and, if necessary, requires the seller to maintain additional securities, so that the value of the collateral is not less than the repurchase price. Default by or bankruptcy of the seller would, however, expose the Company to possible loss because of adverse market action or delays in connection with the disposition of the underlying securities.

      E.     Short Sales — A short sale is a transaction in which the Company sells securities it does not own (but has borrowed) in anticipation of or to hedge against a decline in the market price of the securities. To complete a short sale, the Company may arrange through a broker to borrow the securities to be delivered to the buyer. The proceeds received by the Company for the short sale are retained by the broker until the Company replaces the borrowed securities. In borrowing the securities to be delivered to the buyer, the Company becomes obligated to replace the securities borrowed at their market price at the time of replacement, whatever the price may be.

      All short sales are fully collateralized. The Company maintains assets consisting of cash or liquid securities equal in amount to the liability created by the short sale. These assets are adjusted daily to reflect changes in the value of the securities sold short. The Company is liable for any dividends or distributions paid on securities sold short.

      The Company may also sell short “against the box” (i.e., the Company enters into a short sale as described above while holding an offsetting long position in the security which it sold short). If the Company enters into a short sale “against the box,” the Company segregates an equivalent amount of securities owned as collateral while the short sale is outstanding.

      F.     Option Writing — When the Company writes an option, an amount equal to the premium received by the Company is recorded as a liability and is subsequently adjusted to the current fair value of the option written. Premiums received from writing options that expire unexercised are treated by the Company on the expiration date as realized gains from investments. The difference between the premium and the amount paid on effecting a closing purchase transaction, including brokerage commissions, is also treated as a realized gain, or if the premium is less than the amount paid for the closing purchase transaction, as a realized loss. If a call option is exercised, the premium is added to the proceeds from the sale of the underlying security in determining whether the Company has realized a gain or loss. If a put option is exercised, the premium reduces the cost basis of the securities purchased by the Company. The Company, as the writer of an option, bears the market risk of an unfavorable change in the price of the security underlying the written option. See Note 7 for more detail on options written.

      G.     Security Transactions and Investment Income — Security transactions are accounted for on the date the securities are purchased or sold (trade date). Realized gains and losses are reported on an identified cost basis. Dividend and distribution income is recorded on the ex-dividend date. Distributions received from the Company’s investments in MLPs generally are comprised of income and return of capital. For the fiscal year ended November 30, 2005, the Company estimated that 90% of the MLP distributions received would be treated as a return of capital. The Company recorded as return of capital the amount of $48,831 of dividends and distributions received from MLPs. Included in this amount is an additional return of capital of $404 attributable to MLP distributions received in fiscal 2004 based on the MLP tax reporting information received by the Company in fiscal 2005. This resulted in an equivalent reduction in the cost basis of the associated MLP investments. Net Realized Gains and Net Change in Unrealized Gains in the accompanying Statement of Operations were increased by $1,952 and $46,879, respectively, attributable to the recording of such dividends and distributions as reductions in the cost basis of investments. The Company records investment income and return of capital based on estimates made at the time such distributions are received. Such estimates are based on historical information available from each MLP and other industry sources. These estimates may subsequently be revised based on information received from MLPs after their tax reporting periods are concluded. Interest income is recognized on the accrual basis, including amortization of premiums and accretion of discounts.

NOTES TO FINANCIAL STATEMENTS — (CONTINUED)

      H.     Dividends and Distributions to Stockholders — Dividends to common stockholders are recorded on the ex-dividend date. The character of dividends made during the year may differ from their ultimate characterization for federal income tax purposes. Distributions to stockholders of the Company’s Auction Rate Preferred Stock, Series D are accrued on a daily basis and are determined as described in Note 11. The Company’s dividends will be comprised of return of capital and ordinary income, which is based on the earnings and profits of the Company. The Company is unable to make final determinations as to the character of the dividend until after the end of the calendar year. The Company informed its common stockholders in January 2006 of the character of dividends paid during fiscal year 2005. Prospectively, the Company will inform its common stockholders of the character of dividends during that fiscal year in January following such fiscal year.

      I.     Partnership Accounting Policy — The Company records its pro-rata share of the income/(loss) and capital gains/(losses), to the extent of dividends it has received, allocated from the underlying partnerships and adjusts the cost of the underlying partnerships accordingly. These amounts are included in the Company’s Statement of Operations.

      J.     Federal and State Income Taxation — The Company, as a corporation, is obligated to pay federal and state income tax on its taxable income. The Company invests its assets primarily in MLPs, which generally are treated as partnerships for federal income tax purposes. As a limited partner in the MLPs, the Company includes its allocable share of the MLP’s taxable income in computing its own taxable income. The Company’s tax expense or benefit is included in the Statement of Operations based on the component of income or gains/(losses) to which such expense or benefit relates. Deferred income taxes reflect (i) taxes on unrealized gains/(losses), which are attributable to the difference between fair market value and book basis and (ii) the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. To the extent the Company has a net deferred tax asset, a valuation allowance is recognized if, based on the weight of available evidence, it is more likely than not that some portion or all of the deferred income tax asset is not realized. Future realization of deferred tax assets ultimately depends on the existence of sufficient taxable income of the appropriate character in either the carryback or carryforward period under the tax law.

      The Company may rely to some extent on information provided by the MLPs, which may not necessarily be timely, to estimate taxable income allocable to the MLP units held in the portfolio and to estimate the associated deferred tax liability. Such estimates are made in good faith and reviewed in accordance with the valuation process approved by the Board of Directors. From time to time the Company modifies its estimates or assumptions regarding the deferred tax liability as new information become available.

      K.     Organization Expenses, Offering and Debt Issuance Costs — The Company is responsible for paying all organization expenses, which were expensed when the shares of common stock were issued in the Company’s IPO. Offering costs (including underwriting discount) related to the Company’s two issuances of common stock were charged to additional paid-in capital when the shares were issued. Offering costs (including underwriting discount) related to the issuance of Series D preferred stock were charged to additional paid-in capital when the shares were issued. Debt issuance costs (including underwriting discount) related to the auction rate senior notes payable are being capitalized and amortized over the period the notes are outstanding.

      L.     Derivative Financial Instruments — The Company uses derivative financial instruments (principally interest rate swap contracts) to manage interest rate risk. The Company has established policies and procedures for risk assessment and the approval, reporting and monitoring of derivative financial instrument activities. The Company does not hold or issue derivative financial instruments for speculative purposes. All derivative financial instruments are recorded at fair value with changes in value during the reporting period, and amounts accrued under the agreements, included as unrealized gains or losses in the Statement of Operations. Monthly cash settlements under the terms of the interest rate swap agreements are recorded as realized gains or losses in the Statement of Operations. The Company generally values its interest rate swap

contracts based on dealer quotations, if available, or by discounting the future cash flows from the stated terms of the interest rate swap agreement by using interest rates currently available in the market.

      M.     Indemnifications — Under the Company’s organizational documents, its officers and directors are indemnified against certain liabilities arising out of the performance of their duties to the Company. In addition, in the normal course of business, the Company enters into contracts that provide general indemnification to other parties. The Company’s maximum exposure under these arrangements is unknown, as this would involve future claims that may be made against the Company that have not yet occurred, and may not occur. However, the Company has not had prior claims or losses pursuant to these contracts and expects the risk of loss to be remote.

3. Concentration of Risk

      The Company’s investment objective is to seek a high level of total return with an emphasis on current income paid to its stockholders. Under normal circumstances, the Company intends to invest at least 85% of its total assets in securities of MLPs and other Midstream Energy Companies, and to invest at least 80% of its total assets in MLPs, which are subject to certain risks, such as supply and demand risk, depletion and exploration risk, commodity pricing risk, acquisition risk, and the risk associated with the hazards inherent in midstream energy industry activities. A substantial portion of the cash flow received by the Company is derived from investment in equity securities of MLPs. The amount of cash that an MLP has available for distributions and the tax character of such distributions are dependent upon the amount of cash generated by the MLP’s operations. The Company may invest up to 15% of its total assets in any single issuer and a decline in value of the securities of such an issuer could significantly impact the net asset value of the Company. The Company may invest up to 20% of its total assets in debt securities, which may include below investment grade securities. The Company may, for defensive purposes, temporarily invest all or a significant portion of its assets in investment grade securities, short-term debt securities and cash or cash equivalents. To the extent the Company uses this strategy, it may not achieve its investment objectives.

4. Agreements and Affiliations

      The Company has entered into an Investment Management Agreement with Kayne Anderson under which the Adviser, subject to the overall supervision of the Company’s Board of Directors, manages the day-to-day operations of, and provides investment advisory services to, the Company. For providing these services, the Adviser receives a management fee from the Company equal to the basic management fee or adjusted by the performance fee adjustment, all as described below.

      Pursuant to the Investment Management Agreement, the Company has agreed to pay the Adviser a basic management fee at an annual rate of 1.75% of the Company’s average total assets, adjusting upward or downward (by up to 1.00% of the Company’s average total assets, as defined), depending on to what extent, if any, the Company’s investment performance for the relevant performance period exceeds or trails the Company’s “Benchmark” over the same period. The Company’s Benchmark is the total return (capital appreciation and reinvested dividends) of the Standard & Poor’s 400 Utilities Index plus 600 basis points (6.00%). Each 0.01% of difference of the Company’s performance compared to the performance of the Benchmark is multiplied by a performance fee adjustment of 0.002%, up to a maximum adjustment of 1.00% (as an annual rate). The Company calculates the total management fee based on the average total assets for the prior 12 months. For the period beginning with the commencement of the Company’s operations through September 30, 2005 (the “Initial Period”), on a quarterly fiscal basis the Company paid the Adviser a minimum management fee calculated at an annual rate of 0.75%. After this Initial Period, the basic management fee and the performance fee adjustment are calculated and paid quarterly beginning with the quarter ending November 30, 2005, using a rolling 12-month performance period. Management fees will be accrued monthly.

20

KAYNE ANDERSON MLP INVESTMENT COMPANY

NOTES TO FINANCIAL STATEMENTS — (CONTINUED)

      The performance record for the Benchmark is based on the change in value of the Benchmark during the relevant performance period. During the Company’s first fiscal year, for purposes of calculating the performance fee adjustment, the Company’s initial net asset value was calculated net of the underwriter discount. At November 30, 2005, the Company accrued management fees at an annual rate of 0.87% of total assets (1.17% of net assets applicable to common stockholders) based on the Company’s investment performance for the period December 1, 2004 through November 30, 2005.

      For purposes of calculating the management fee, the Company’s total assets are equal to the Company’s average monthly gross asset value (which includes assets attributable to or proceeds from the Company’s use of preferred stock, commercial paper or notes issuances and other borrowings), minus the sum of the Company’s accrued and unpaid dividends on any outstanding common stock and accrued and unpaid dividends on any outstanding preferred stock and accrued liabilities (other than liabilities associated with borrowing or leverage by the Company and any accrued taxes). Liabilities associated with borrowing or leverage by the Company include the principal amount of any borrowings, commercial paper or notes issued by the Company, the liquidation preference of any outstanding preferred stock, and other liabilities from other forms of borrowing or leverage such as short positions and put or call options held or written by the Company.

      For the fiscal year ended November 30, 2005, KA Associates, Inc., an affiliate of the Adviser, earned approximately $12 in brokerage commissions from portfolio transactions executed on behalf of the Company.

5. Income Taxes

      Deferred income taxes reflect (i) taxes on unrealized gains/(losses), which are attributable to the difference between fair market value and book basis and (ii) the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. Components of the Company’s deferred tax assets and liabilities as of November 30, 2005 are as follows:

Deferred tax assets:
	Organizational costs	$	(45	)
Deferred tax liabilities:
	Unrealized gains on investment securities		37,371
	Distributions received from MLPs — return of capital		18,608
Total net deferred tax liability		$	55,934

      At November 30, 2005, the Company did not record a valuation allowance against its deferred tax assets.

      The components of income tax expense include $50,903 and $4,945 for deferred federal income taxes and state income taxes (net of the federal tax benefit), respectively. Total income taxes have been computed by applying the Federal statutory income tax rate plus a blended state income tax rate totaling 38.5% to net investment income and realized and unrealized gains on investments before taxes.

      At November 30, 2005, the cost basis of investments for Federal income tax purposes was $1,180,135 and the cash received on securities sold short was $392. At November 30, 2005, gross unrealized appreciation and depreciation of investments and securities sold short for Federal income tax purposes were as follows:

Gross unrealized appreciation of investments (including securities sold short)	$	156,222
Gross unrealized depreciation of investments (including securities sold short)		(14,219	)
Net unrealized appreciation before tax and interest rate swap contracts		142,003
Unrealized appreciation on interest rate swap contracts		3,398
Net unrealized appreciation before tax	$	145,401
Net unrealized appreciation after tax	$	89,422

      The Company has an uncommitted revolving credit line with Custodial Trust Company (an affiliate of the administrator, Bear Stearns Funds Management Inc.), under which the Company may borrow from Custodial Trust Company an aggregate amount of up to the lesser of $200,000 or the maximum amount the Company is permitted to borrow under the 1940 Act, subject to certain limitations imposed by the lender. For the fiscal year ended November 30, 2005, the average amount outstanding was $13,233, with a weighted average interest rate of 3.87%. As of November 30, 2005, the Company had no outstanding borrowings on the revolving credit line. Any loans under this line are repayable on demand by the lender at any time.

10. Auction Rate Senior Notes

      On March 28, 2005, the Company issued three series of auction rate senior notes, each with a maturity of 40 years, having an aggregate principal amount of $260,000 (“Senior Notes”). The Senior Notes were issued in denominations of $25. The principal amount of the Senior Notes will be due and payable on various dates as follows: Series A on April 3, 2045, Series B on April 5, 2045 and Series C on March 31, 2045. Fair value of the notes approximates carrying amount because the interest rate fluctuates with changes in interest rates available in the current market.

      Holders of the Notes are entitled to receive cash interest payments at an annual rate that may vary for each rate period. Interest rates for Series A, Series B and Series C as of November 30, 2005 were 4.21%, 4.18% and 4.24%, respectively. The weighted average interest rates for Series A, Series B and Series C for the period from March 28, 2005 through November 30, 2005, were 3.55%, 3.58% and 3.64%, respectively. These rates include the applicable rate based on the latest results of the auction, plus commissions paid to the auction agent in the amount of 0.25%. For each subsequent rate period, the interest rate will be determined by an auction conducted in accordance with the procedures described in the Notes’ prospectus. The reset rate period for Series A and Series B Notes is seven days, while Series C Notes reset every 28 days. The Notes are not listed on any exchange or automated quotation system.

      The Notes are redeemable in certain circumstances at the option of the Company. The Notes are also subject to a mandatory redemption if the Company fails to meet an asset coverage ratio required by law, or fails to cure deficiency as stated in the Company’s rating agency guidelines in a timely manner.

      The Notes are unsecured obligations of the Company and, upon liquidation, dissolution or winding up of the Company, will rank: (1) senior to all the Company’s outstanding preferred shares; (2) senior to all of the Company’s outstanding common shares; (3) on a parity with any unsecured creditors of the Company and any unsecured senior securities representing indebtedness of the Company; and (4) junior to any secured creditors of the Company.

11. Preferred Stock

      On April 12, 2005, the Company issued 3,000 shares of Series D auction rate preferred stock totaling $75,000. The Company has 10,000 shares of authorized preferred stock. The preferred stock has rights determined by the board of Directors. The preferred stock has a liquidation value of $25,000 per share plus any accumulated, but unpaid dividends, whether or not declared.

      Holders of preferred stock are entitled to receive cash dividend payments at an annual rate that may vary for each rate period. The dividend rate as of November 30, 2005 was 4.35%. The weighted average dividend rate for the period April 12, 2005 through November 30, 2005, was 3.77%. This rate includes the applicable rate based on the latest results of the auction, plus commissions paid to the auction agent in the amount of 0.25%. Under the 1940 Act, the Company may not declare dividends or make other distribution on shares of common stock or purchases of such shares if, at any time of the declaration, distribution or purchase, asset coverage with respect to the outstanding preferred stock would be less than 200%.

      The preferred stock is redeemable in certain circumstances at the option of the Company. The preferred stock is also subject to a mandatory redemption if the Company fails to meet an asset coverage ratio required by law, or fails to cure deficiency as stated in the Company’s rating agency guidelines in a timely manner.

      The holders of the preferred stock have voting rights equal to the holders of common stock (one vote per share) and will vote together with the holders of shares of common stock as a single class except on matters affecting only the holders of preferred stock or the holders of common stock.

NOTES TO FINANCIAL STATEMENTS — (CONCLUDED)

12. Interest Rate Swap Contracts

      The Company has entered into interest rate swap contracts to partially hedge itself from increasing interest expense on its leverage resulting from increasing short-term interest rates. A decline in interest rates may result in a decline in the value of the swap contracts, which, everything else being held constant, would result in a decline in the net assets of the Company. In addition, if the counterparty to the interest rate swap contracts defaults, the Company would not be able to use the anticipated receipts under the swap contracts to offset the interest payments on the Company’s leverage. At the time the interest rate swap contracts reach their scheduled termination, there is a risk that the Company would not be able to obtain a replacement transaction or that the terms of the replacement transaction would not be as favorable as on the expiring transaction. In addition, if the Company is required to terminate any swap contract early, then the Company could be required to make a termination payment. As of November 30, 2005, the Company has entered into nine interest rate swap contracts with UBS AG as summarized below:

      At November 30, 2005, the weighted average duration of the interest rate swap contracts was 4.1 years and the weighted average fixed rate was 4.42%. The Company is exposed to credit risk on the interest rate swap contracts if the counterparty should fail to perform under the terms of the interest rate swap contracts.

13. Common Stock

      The Company has 199,990,000 shares of common stock authorized and 37,175,551 shares outstanding at November 30, 2005. As of that date, Kayne Anderson owned 4,000 shares. Transactions in common shares for the fiscal year ended November 30, 2005, were as follows:

Shares at November 30, 2004	33,165,900
Shares issued through reinvestment of distributions	1,009,651
Shares issued in connection with the secondary public offering of common stock	3,000,000
Shares at November 30, 2005	37,175,551

14. Subsequent Events

      On December 14, 2005, the Company announced the successful completion of its $60,000 offering of Series E Auction Rate Senior Notes (“Series E Senior Notes”). The Series E Senior Notes are rated ‘Aaa’ and ‘AAA’ by Moody’s Investors Service, Inc. and Fitch Ratings, respectively. The initial interest rate on the Series E Senior Notes was 4.05%. The subsequent interest rates for the Series E Notes will be determined at weekly auctions.

      On January 12, 2006, the Company paid a dividend to its common stockholders in the amount of $0.425 per share, for a total of $15,800. Of this total, pursuant to the Company’s dividend reinvestment plan, $6,627 was reinvested into the Company for 263,620 newly issued shares of common stock.

An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, and evaluating the overall financial statement presentation. We believe that our audits, which included confirmation of securities owned at November 30, 2005 by correspondence with the custodian and brokers, provide a reasonable basis for our opinion.

KAYNE ANDERSON MLP INVESTMENT COMPANY

DIVIDEND REINVESTMENT PLAN

(UNAUDITED)

      Kayne Anderson MLP Investment Company, a Maryland corporation (the “Company”), hereby adopts the following plan (the “Plan”) with respect to distributions declared by its Board of Directors (the “Board”) on shares of its Common Stock:

      1. Unless a stockholder specifically elects to receive cash as set forth below, all distributions hereafter declared by the Board shall be payable in shares of the Common Stock of the Company, and no action shall be required on such stockholder’s part to receive a distribution in stock.

      2. Such distributions shall be payable on such date or dates as may be fixed from time to time by the Board to stockholders of record at the close of business on the record date(s) established by the Board for the distribution involved.

      3. The Company may use newly-issued shares of its Common Stock or purchase shares in the open market in connection with the implementation of the plan. The number of shares to be issued to a stockholder shall be determined as follows: (a) If the Company’s Common Stock is trading at or above net asset value at the time of valuation, the Company will issue new shares at a price equal to the greater of (i) the Company’s Common Stock’s net asset value on that date or (ii) 95% of the market price of the Company’s Common Stock on that date; (b) If the Company’s Common Stock is trading below net asset value at the time of valuation, the Plan Administrator will receive the dividend or distribution in cash and will purchase Common Stock in the open market, on the New York Stock Exchange or elsewhere, for the Participants’ accounts, except that the Plan Administrator will endeavor to terminate purchases in the open market and cause the Company to issue the remaining shares if, following the commencement of the purchases, the market value of the shares, including brokerage commissions, exceeds the net asset value at the time of valuation. These remaining shares will be issued by the Company at a price equal to the greater of (i) the net asset value at the time of valuation or (ii) 95% of the then current market price.

      4. In a case where the Plan Administrator has terminated open market purchases and caused the issuance of remaining shares by the Company, the number of shares received by the participant in respect of the cash dividend or distribution will be based on the weighted average of prices paid for shares purchased in the open market, including brokerage commissions, and the price at which the Company issues remaining shares. To the extent that the Plan Administrator is unable to terminate purchases in the open market before the Plan Administrator has completed its purchases, or remaining shares cannot be issued by the Company because the Company declared a dividend or distribution payable only in cash, and the market price exceeds the net asset value of the shares, the average share purchase price paid by the Plan Administrator may exceed the net asset value of the shares, resulting in the acquisition of fewer shares than if the dividend or distribution had been paid in shares issued by the Company.

      5. A stockholder may, however, elect to receive his or its distributions in cash. To exercise this option, such stockholder shall notify American Stock Transfer & Trust Company, the plan administrator and the Company’s transfer agent and registrar (collectively the “Plan Administrator”), in writing so that such notice is received by the Plan Administrator no later than the record date fixed by the Board for the distribution involved.

      6. The Plan Administrator will set up an account for shares acquired pursuant to the Plan for each stockholder who has not so elected to receive dividends and distributions in cash (each, a “Participant”). The Plan Administrator may hold each Participant’s shares, together with the shares of other Participants, in non-certificated form in the Plan Administrator’s name or that of its nominee. Upon request by a Participant, received no later than three (3) days prior to the payable date, the Plan Administrator will, instead of crediting shares to and/or carrying shares in a Participant’s account, issue, without charge to the Participant, a certificate registered in the Participant’s name for the number of whole shares payable to the Participant and a check for any fractional share less a broker commission on the sale of such fractional shares. If a request to terminate a Participant’s participation in the Plan is received less than three (3) days before the payable date, dividends and distributions for that payable date will be reinvested. However, subsequent dividends and distributions will be paid to the Participant in cash.

      7. The Plan Administrator will confirm to each Participant each acquisition made pursuant to the Plan as soon as practicable but not later than 10 business days after the date thereof. Although each Participant may from time to time have an undivided fractional interest (computed to three decimal places) in a share of

27

KAYNE ANDERSON MLP INVESTMENT COMPANY

DIVIDEND REINVESTMENT PLAN — (CONCLUDED)

(UNAUDITED)

Common Stock of the Company, no certificates for a fractional share will be issued. However, dividends and distributions on fractional shares will be credited to each Participant’s account. In the event of termination of a Participant’s account under the Plan, the Plan Administrator will adjust for any such undivided fractional interest in cash at the market value of the Company’s shares at the time of termination.

      8. The Plan Administrator will forward to each Participant any Company related proxy solicitation materials and each Company report or other communication to stockholders, and will vote any shares held by it under the Plan in accordance with the instructions set forth on proxies returned by Participants to the Company.

      9. In the event that the Company makes available to its stockholders rights to purchase additional shares or other securities, the shares held by the Plan Administrator for each Participant under the Plan will be added to any other shares held by the Participant in certificated form in calculating the number of rights to be issued to the Participant.

      10. The Plan Administrator’s service fee, if any, and expenses for administering the Plan will be paid for by the Company.

      11. Each Participant may terminate his or its account under the Plan by so notifying the Plan Administrator via the Plan Administrator’s website at www.amstock.com, by filling out the transaction request form located at the bottom of the Participant’s Statement and sending it to American Stock Transfer and Trust Company, P.O. Box 922, Wall Street Station, New York, NY 10269-0560 or by calling the Plan Administrator at (888) 888-0317. Such termination will be effective immediately. The Plan may be terminated by the Company upon notice in writing mailed to each Participant at least 30 days prior to any record date for the payment of any dividend or distribution by the Company. Upon any termination, the Plan Administrator will cause a certificate or certificates to be issued for the full shares held for the Participant under the Plan and a cash adjustment for any fractional share to be delivered to the Participant without charge to the Participant. If a Participant elects by his or its written notice to the Plan Administrator in advance of termination to have the Plan Administrator sell part or all of his or its shares and remit the proceeds to the Participant, the Plan Administrator is authorized to deduct a $15.00 transaction fee plus a $0.10 per share brokerage commission from the proceeds.

      12. These terms and conditions may be amended or supplemented by the Company at any time but, except when necessary or appropriate to comply with applicable law or the rules or policies of the Securities and Exchange Commission or any other regulatory authority, only by mailing to each Participant appropriate written notice at least 30 days prior to the effective date thereof.

Any such amendment may include an appointment by the Plan Administrator in its place and stead of a successor agent under these terms and conditions, with full power and authority to perform all or any of the acts to be performed by the Plan Administrator under these terms and conditions. Upon any such appointment of any agent for the purpose of receiving dividends and distributions, the Company will be authorized to pay to such successor agent, for each Participant’s account, all dividends and distributions payable on shares of the Company held in the Participant’s name or under the Plan for retention or application by such successor agent as provided in these terms and conditions.

      13. The Plan Administrator will at all times act in good faith and use its best efforts within reasonable limits to ensure its full and timely performance of all services to be performed by it under this Plan and to comply with applicable law, but assumes no responsibility and shall not be liable for loss or damage due to errors unless such error is caused by the Plan Administrator’s negligence, bad faith, or willful misconduct or that of its employees or agents.

      14. These terms and conditions shall be governed by the laws of the State of Maryland.
