INVESTMENT MANAGEMENT INC. (C) 2004 MORGAN STANLEY INVESTMENT ADVISER <Page> MORGAN STANLEY HIGH YIELD FUND, INC. LETTER TO STOCKHOLDERS Overview PERFORMANCE For the six months ended June 30, 2004, the Morgan Stanley High Yield Fund, Inc. (the "Fund") had a total return, based on net asset value per share of 1.83% compared to 2.47% for the CSFB High Yield Index (the "Index"). On June 30, 2004, the closing price of the Fund's shares on the New York Stock Exchange was $5.91, representing a 13.3% discount to the Fund's net asset value per share. FACTORS AFFECTING PERFORMANCE - In the first half of 2004, the high-yield market benefited from a strong economic environment, good corporate earnings and very low defaults. Unfortunately, a poor technical situation caused by very large new issuance and outflows from the asset class kept high-yield from continuing the strong rally that began in late 2002. - High-yield spreads tightened by 30 basis points during the period to close at 456 basis points over treasuries while the yield to maturity of the Index rose to 8.57% due to the significantly higher treasury yields. - Lower-rated securities were the best performers during the period partly due to the decline in treasury prices, which had a greater impact on higher rated securities. - Consumer products, metals, manufacturing and chemicals were the best performers industries with returns over 6% while aerospace and telecommunications produced negative returns. The airline industry, which is a sub-sector of aerospace, took a particularly hard hit, declining almost 20%. As the Fund did not own airlines in 2004, this benefited performance. - Good security selection in housing, wireless communications and telecommunications added to relative performance during the first half of 2004. Security selection in cable, forest products and chemicals detracted from returns. MANAGEMENT STRATEGIES - The Fund's main overweighted sectors are energy, housing and diversified media while our main sector underweights include airlines, financials, information technology, gaming/leisure and utilities. As a reminder, our sector allocations are the result of our bottom-up security selection. - In regards to credit quality, the Fund has a slightly higher average credit quality than the overall market.

NOTES TO FINANCIAL STATEMENTS June 30, 2004 (Unaudited) Morgan Stanley High Yield Fund, Inc. (the "Fund") was incorporated on September 23, 1993 and is registered as a non-diversified, closed-end management investment company under the Investment Company Act of 1940 (the "1940 Act"), as amended. The Fund's primary objective is to produce high current income and as a secondary objective, to seek capital appreciation, through investments primarily in high yield securities. A. ACCOUNTING POLICIES: The following significant accounting policies are in conformity with accounting principles generally accepted in the United States. Such policies are consistently followed by the Fund in the preparation of its financial statements. Accounting principles generally accepted in the United States may require management to make estimates and assumptions that affect the reported amounts and disclosures in the financial statements. Actual results may differ from those estimates. 1. SECURITY VALUATION: Equity securities listed on a U.S. exchange are valued at the latest quoted sales price on the valuation date. Equity securities listed or traded on NASDAQ, for which market quotations are available, are valued at the NASDAQ Official Closing Price. Securities listed on a foreign exchange are valued at their closing price. Unlisted securities and listed securities not traded on the valuation date for which market quotations are readily available are valued at the mean between the current bid and asked prices obtained from reputable brokers. Bonds and other fixed income securities may be valued according to the broadest and most representative market. In addition, bonds and other fixed income securities may be valued on the basis of prices provided by a pricing service. The prices provided by a pricing service take into account broker dealer market price quotations for institutional size trading in similar groups of securities, security quality, maturity, coupon and other security characteristics as well as any developments related to the specific securities. Debt securities purchased with remaining maturities of 60 days or less are valued at amortized cost, if it approximates value. All other securities and investments for which market values are not readily available, including restricted securities, and those securities for which it is inappropriate to determine prices in accordance with the aforementioned procedures, are valued at fair value as determined in good faith under procedures adopted by the Board of Directors, although the actual calculations may be done by others. Factors considered in making this determination may include, but are not limited to, information obtained by contacting the issuer, analysts, or the appropriate stock exchange (for exchange-traded securities), analysis of the issuer's financial statements or other available documents and, if necessary, available information concerning other securities in similar circumstances. Most foreign markets close before the New York Stock Exchange (NYSE). Occasionally, developments that could affect the closing prices of securities and other assets may occur between the times at which valuations of such securities are determined (that is, close of the foreign market on which the securities trade) and the close of business on the NYSE. If these developments are expected to materially affect the value of the securities, the valuations may be adjusted to reflect the estimated fair value as of the close of the NYSE, as determined in good faith under procedures established by the Board of Directors. 2. REPURCHASE AGREEMENTS: The Fund may enter into repurchase agreements under which the Fund lends excess cash and takes possession of securities with an agreement that the counterparty will repurchase such securities. In connection with transactions in repurchase agreements, a bank as custodian for the Fund takes possession of the underlying securities (collateral), with a market value at least equal to the amount of the repurchase transaction, including principal and accrued interest. To the extent that any repurchase transaction exceeds one business day, the value of the collateral is marked-to-market on a daily basis to determine the adequacy of the collateral. In the event of default on the obligation to repurchase, the Fund has the right to liquidate the collateral and apply the proceeds in satisfaction of the obligation. In the event of default or bankruptcy by the counter-party to the agreement, realization and/or retention of the collateral or proceeds may be subject to legal proceedings. The Fund, along with other affiliated investment companies, may utilize a joint trading account for the purpose of entering into one or more repurchase agreements. 3. REVERSE REPURCHASE AGREEMENTS: The Fund may enter into reverse repurchase agreements with institutions that the Fund's investment adviser has determined are creditworthy. Under a reverse repurchase agreement, the Fund sells securities and agrees to repurchase them at a mutually agreed upon date and price. Reverse repurchase agreements involve the risk that the market value of the securities purchased with the proceeds from the sale of securities received by the Fund may decline below the price of the securities the Fund is obligated to repurchase. Reverse repurchase agreements also involve credit risk with the counterparty to the extent that the value of securities subject to repurchase exceed the Fund's 13 <Page> MORGAN STANLEY HIGH YIELD FUND, INC. NOTES TO FINANCIAL STATEMENTS (CONT'D) June 30, 2004 (Unaudited) liability under the reverse repurchase agreement. Securities subject to repurchase under reverse repurchase agreements, if any, are designated as such in the Statement of Net Assets. At June 30, 2004, the Fund had a reverse repurchase agreement outstanding with UBS Warburg as follows: <Table> <Caption> MATURITY IN LESS THAN 365 DAYS - ---------------------------------------------------------------- Value of Securities Subject to Repurchase $26,553,000 Liability Under Reverse Repurchase Agreement $25,905,000 Weighted Average Days to Maturity 11 </Table> The weighted average weekly balance of reverse repurchase agreements outstanding during the six months ended June 30, 2004 was approximately $13,287,000 at a weighted average weekly interest rate of 1.50%. 4. FOREIGN CURRENCY TRANSLATION: The books and records of the Fund are maintained in U.S. dollars. Foreign currency amounts are translated into U.S. dollars at the mean of the bid and asked prices of such currencies against U.S. dollars last quoted by a major bank as follows: - investments, other assets and liabilities at the prevailing rates of exchange on the valuation date; - investment transactions and investment income at the prevailing rates of exchange on the dates of such transactions. Although the net assets of the Fund are presented at the foreign exchange rates and market values at the close of the period, the Fund does not isolate that portion of the results of operations arising as a result of changes in the foreign exchange rates from the fluctuations arising from changes in the market prices of the securities held at period end. Similarly, the Fund does not isolate the effect of changes in foreign exchange rates from the fluctuations arising from changes in the market prices of securities sold during the period. Accordingly, realized and unrealized foreign currency gains (losses) due to securities transactions are included in the reported net realized and unrealized gains (losses) on investment transactions and balances. Net realized gains (losses) on foreign currency transactions represent net foreign exchange gains (losses) from sales and maturities of foreign currency exchange contracts, disposition of foreign currencies, currency gains or losses realized between the trade and settlement dates on securities transactions, and the difference between the amount of investment income and foreign withholding taxes recorded on the Fund's books and the U.S. dollar equivalent amounts actually received or paid. Net unrealized currency gains (losses) from valuing foreign currency denominated assets and liabilities at period end exchange rates are reflected as a component of unrealized appreciation (depreciation) on investments and foreign currency translations in the Statement of Net Assets. The change in net unrealized currency gains (losses) on foreign currency translations for the period is reflected in the Statement of Operations. Foreign security and currency transactions may involve certain considerations and risks not typically associated with those of U.S. dollar denominated transactions as a result of, among other factors, the possibility of lower levels of governmental supervision and regulation of foreign securities markets and the possibility of political or economic instability. The Fund may use derivatives to achieve its investment objectives. The Fund may engage in transactions in futures contracts on foreign currencies, stock indices, as well as in options, swaps and structured notes. Consistent with the Fund's investment objectives and policies, the Fund may use derivatives for non-hedging as well as hedging purposes. Following is a description of derivative instruments that the Fund have utilized and their associated risks: 5. FOREIGN CURRENCY EXCHANGE CONTRACTS: The Fund may enter into foreign currency exchange contracts generally to attempt to protect securities and related receivables and payables against changes in future foreign exchange rates and, in certain situations, to gain exposure to a foreign currency. A foreign currency exchange contract is an agreement between two parties to buy or sell currency at a set price on a future date. The market value of the contract will fluctuate with changes in currency exchange rates. The contract is marked-to-market daily and the change in market value is recorded by the Fund as unrealized gain or loss. The Fund records realized gains or losses when the contract is closed equal to the difference between the value of the contract at the time it was opened and the value at the time it was closed. Risk may arise upon entering into these contracts from the potential inability of counter parties to meet the terms of their contracts and is generally limited to the amount of unrealized gain on the contracts, if any, at the date of default. Risks may also arise from unanticipated movements in the value of a foreign currency relative to the U.S. dollar. 6. STRUCTURED SECURITIES: The Fund may invest in interests in entities organized and operated solely for the purpose of 14 <Page> MORGAN STANLEY HIGH YIELD FUND, INC. NOTES TO FINANCIAL STATEMENTS (CONT'D) June 30, 2004 (Unaudited) restructuring the investment characteristics of sovereign debt obligations. This type of restructuring involves the deposit with or purchase by an entity of specified instruments and the issuance by that entity of one or more classes of securities ("Structured Securities") backed by, or representing interests in, the underlying instruments. Structured Securities generally will expose the Fund to credit risks of the underlying instruments as well as of the issuer of the Structured Security. Structured Securities are typically sold in private placement transactions with no active trading market. Investments in Structured Securities may be more volatile than their underlying instruments, however, any loss is limited to the amount of the original investment. 7. FUTURES: The Fund may purchase and sell futures contracts. Futures contracts provide for the sale by one party and purchase by another party of a specified amount of a specified security, index, instrument or basket of instruments. Futures contracts (secured by cash or government securities deposited with brokers or custodians as "initial margin") are valued based upon their quoted daily settlement prices; changes in initial settlement value (represented by cash paid to or received from brokers as "variation margin") are accounted for as unrealized appreciation (depreciation). When futures contracts are closed, the difference between the opening value at the date of purchase and the value at closing is recorded as realized gains or losses in the Statement of Operations. The Fund may use futures contracts in order to manage exposure to the stock and bond markets, to hedge against unfavorable changes in the value of securities or to remain fully invested and to reduce transaction costs. Futures contracts involve market risk in excess of the amounts recognized in the Statement of Net Assets. Risks arise from the possible movements in security values underlying these instruments. The change in value of futures contracts primarily corresponds with the value of their underlying instruments, which may not correlate with the change in value of the hedged investments. In addition, there is the risk that the Fund may not be able to enter into a closing transaction because of an illiquid secondary market. 8. OVER-THE-COUNTER TRADING: Securities and other derivative instruments that may be purchased or sold by the Fund may consist of instruments not traded on an exchange. The risk of nonperformance by the obligor on such an instrument may be greater, and the ease with which the Fund can dispose of or enter into closing transactions with respect to such an instrument may be less, than in the case of an exchange-traded instrument. In addition, significant disparities may exist between bid and asked prices for derivative instruments that are not traded on an exchange. Derivative instruments not traded on exchanges are also not subject to the same type of government regulation as exchange traded instruments, and many of the protections afforded to participants in a regulated environment may not be available in connection with such transactions. 9. OTHER: Security transactions are accounted for on the date the securities are purchased or sold. Realized gains and losses on the sale of investment securities are determined on the specific identified cost basis. Interest income is recognized on the accrual basis and discounts and premiums on investments purchased are accreted or amortized in accordance with the effective yield method over their respective lives, except where collection is in doubt. Distributions to stockholders are recorded on the ex-dividend date. B. ADVISER: Morgan Stanley Investment Management Inc. (the "Adviser") provides investment advisory services to the Fund under the terms of an Investment Advisory and Management Agreement (the "Agreement"). Under the Agreement, the Adviser is paid a fee computed weekly and payable monthly at an annual rate of 0.70% of the Fund's average weekly net assets. C. ADMINISTRATOR: JPMorgan Chase Bank, through its corporate affiliate J.P. Morgan Investor Services Co. (the "Administrator"), provides administrative services to the Fund under an Administration Agreement. The Administrator is paid a fee computed weekly and payable monthly at an annual rate of 0.02435% of the Fund's average weekly net assets, plus $24,000 per annum. In addition, the Fund is charged for certain out-of-pocket expenses incurred by the Administrator on its behalf. An employee of the Administrator is an Officer of the fund. D. CUSTODIAN: JPMorgan Chase Bank and its affiliates serve as custodian for the Fund. The Custodian holds cash, securities, and other assets of the Fund as required by the 1940 Act. Custody fees are payable monthly based on assets held in custody, investment purchases and sales activity and account maintenance fees, plus reimbursement for certain out-of-pocket expenses. E. FEDERAL INCOME TAXES: It is the Fund's intention to continue to qualify as a regulated investment company and distribute all of its taxable income. Accordingly, no provision for Federal income taxes is required in the financial statements. Dividend income and distributions to stockholders are recorded on the ex-dividend date. The Fund may be subject to taxes imposed by countries in which it invests. Such taxes are generally based on income and/or 15 <Page> MORGAN STANLEY HIGH YIELD FUND, INC. NOTES TO FINANCIAL STATEMENTS (CONT'D) June 30, 2004 (Unaudited) capital gains earned or repatriated. Taxes are accrued and applied to net investment income, net realized gains and net unrealized appreciation as such income and/or gains are earned. The tax character of distributions paid may differ from the character of distributions shown on the Statements of Changes in Net Assets due to short-term capital gains being treated as ordinary income for tax purposes. The tax character of distributions paid during 2003 and 2002 were as follows: <Table> <Caption> 2003 DISTRIBUTIONS 2002 DISTRIBUTIONS PAID FROM: PAID FROM: (000) (000) - --------------------------------- ------------------------ LONG-TERM LONG-TERM ORDINARY CAPITAL ORDINARY CAPITAL INCOME GAIN INCOME GAIN - ------------------------------------------------------------ $6,671 $-- $9,048 $-- </Table> The amount and character of income and capital gain distributions to be paid by the Fund are determined in accordance with Federal income tax regulations, which may differ from accounting principles generally accepted in the United States. The book/tax differences are considered either temporary or permanent in nature. Temporary differences are attributable to differing book and tax treatments for the timing of the recognition of gains and losses on certain investment transactions and the timing of the deductibility of certain expenses. Permanent book and tax basis differences may result in reclassifications among undistributed (distributions in excess of) net investment income (or accumulated net investment loss), accumulated net realized gain (loss) and paid-in capital. At December 31, 2003, the components of distributable earnings on a tax basis were as follows: <Table> <Caption> UNDISTRIBUTED UNDISTRIBUTED ORDINARY INCOME LONG-TERM CAPITAL GAIN (000) (000) - ---------------------------------------------------- $115 $-- ==================================================== </Table> At June 30, 2004, the Federal income tax cost basis of securities was $108,290,000 and, accordingly, net unrealized depreciation for Federal income tax purposes was $1,392,000 of which $7,153,000 related to appreciated securities and $8,545,000 related to depreciated securities. At December 31, 2003, the Fund had a capital loss carryforward for U.S. Federal income tax purposes of approximately $72,207,000 available to offset future capital gains of which $1,337,000 will expire on December 31, 2007, $4,197,000 will expire on December 31, 2008, $4,214,000 to expire on December 31, 2009, $24,375,000 will expire on December 31, 2010 and $38,084,000 will expire on December 31, 2011. To the extent that capital loss carryforwards are used to offset any future capital gains realized during the carryforward period as provided by U.S. Federal income tax regulations, no capital gains tax liability will be incurred by the Fund for gains realized and not distributed. To the extent that capital gains are offset, such gains will not be distributed to the stockholders. Net capital and currency losses incurred after October 31, and within the taxable year are deemed to arise on the first business day of the Fund's next taxable year. For the year ended December 31, 2003, the Fund deferred to January 1, 2004, for U.S. Federal income tax purposes, post-October capital losses of $3,413,000 and post-October currency losses of $82,000. F. CONTRACTUAL OBLIGATIONS: The Fund enters into contracts that contain a variety of indemnifications. The Fund's maximum exposure under these arrangements is unknown. However, the Fund has not had prior claims or losses pursuant to these contracts and expects the risk of loss to be remote. G. OTHER: During the six months ended June 30, 2004, the Fund made purchases and sales totaling approximately $29,888,000 and $30,405,000, respectively, of investment securities other than long-term U.S. Government securities and short-term investments. There were no purchases or sales of long-term U.S. Government securities. A substantial portion of the Fund's total investments consist of high yield securities rated below investment grade. Investments in high-yield securities are accompanied by a greater degree of credit risk and the risk tends to be more sensitive to economic conditions than higher-rated securities. These investments are often traded by one market maker who may also be utilized by the Fund to provide pricing information used to value such securities. The amounts which will be realized upon disposition of the securities may differ from the value reflected on the statement of net assets and the differences could be material. On June 21, 2004, the Board of Directors declared a distribution of $0.04 per share, derived from net investment income, payable on July 15, 2004, to stockholders of record on June 30, 2004. 16 <Page> MORGAN STANLEY HIGH YIELD FUND, INC.

This information is also available on the Securities and Exchange Commission's website at www.sec.gov. 17 <Page> MORGAN STANLEY HIGH YIELD FUND, INC. DIVIDEND REINVESTMENT AND CASH PURCHASE PLAN Pursuant to the Dividend Reinvestment and Cash Purchase Plan (the "Plan"), each stockholder will be deemed to have elected, unless American Stock Transfer & Trust Company (the "Plan Agent") is otherwise instructed by the stockholder in writing, to have all distributions automatically reinvested in Fund shares. Participants in the Plan have the option of making additional voluntary cash payments to the Plan Agent, annually, in any amount from $100 to $3,000, for investment in Fund shares. Dividend and capital gain distributions will be reinvested on the reinvestment date in full and fractional shares. If the market price per share equals or exceeds net asset value per share on the reinvestment date, the Fund will issue shares to participants at net asset value. If net asset value is less than 95% of the market price on the reinvestment date, shares will be issued at 95% of the market price. If net asset value exceeds the market price on the reinvestment date, participants will receive shares valued at market price. The Fund may purchase shares of its Common Stock in the open market in connection with dividend reinvestment requirements at the discretion of the Board of Directors. Should the Fund declare a dividend or capital gain distribution payable only in cash, the Plan Agent will purchase Fund shares for participants in the open market as agent for the participants. The Plan Agent's fees for the reinvestment of dividends and distributions will be paid by the Fund. However, each participant's account will be charged a pro rata share of brokerage commissions incurred on any open market purchases effected on such participant's behalf. A participant will also pay brokerage commissions incurred on purchases made by voluntary cash payments. Although stockholders in the Plan may receive no cash distributions, participation in the Plan will not relieve participants of any income tax which may be payable on such dividends or distributions. In the case of stockholders, such as banks, brokers or nominees, that hold shares for others who are the beneficial owners, the Plan Agent will administer the Plan on the basis of the number of shares certified from time to time by the stockholder as representing the total amount registered in the stockholder's name and held for the account of beneficial owners who are participating in the Plan. Stockholders who do not wish to have distributions automatically reinvested should notify the Plan Agent in writing. There is no penalty for non-participation or withdrawal from the Plan, and stockholders who have previously withdrawn from the Plan may rejoin at any time. Requests for additional information or any correspondence concerning the Plan should be directed to the Plan Agent at: Morgan Stanley High Yield Fund, Inc.
