================================================================================ MassMutual CORPORATE INVESTORS REPORT for the THREE MONTHS ENDED 3/31/03 ================================================================================ MASSMUTUAL CORPORATE INVESTORS ADVISER c/o David L. Babson & Company Inc. David L. Babson & Company Inc., 1500 Main Street, Suite 1100 a member of the MassMutual Financial Group Springfield, Massachusetts 01115 (413) 226-1516 AUDITOR www.massmutual.com/mci Deloitte & Touche, LLP New York, New York 10281 CUSTODIAN Citibank, N.A. New York, New York 10043 TRANSFER AGENT & REGISTRAR Shareholder Financial Services, Inc. P.O. Box 173673 Denver, Colorado 80217-3673 1-800-647-7374 Internet website: www.massmutual.com/mci INVESTMENT OBJECTIVE AND POLICY MassMutual Corporate Investors (the "Trust"), a non-diversified closed-end investment company, was offered to the public in September 1971 and its shares are listed on the New York Stock Exchange. The share price of Corporate Investors can be found in the financial section of most newspapers as "MassCp" or "MassMuInv" under the New York Stock Exchange listings. The Trust's New York Stock Exchange trading symbol is "MCI". The Trust's investment objective is to maintain a portfolio of securities providing a fixed yield and at the same time offering an opportunity for capital gains. The Trust's principal investments are privately placed, below-investment grade, long-term corporate debt obligations with equity features such as warrants, conversion rights, or other equity features and, occasionally, preferred stocks. The Trust typically purchases these investments, which are not publicly tradable, directly from their issuers, which tend to be smaller companies. In addition, the Trust may temporarily invest, subject to certain limitations, in marketable investment grade debt securities, other marketable debt securities (including high yield securities) and marketable common stocks. David L. Babson & Company Inc. manages the Trust on a total return basis. The Trust distributes substantially all of its net income to shareholders each year. Accordingly, the Trust pays dividends to shareholders quarterly in January, May, August, and November. The Trust pays dividends to its shareholders in cash, unless the shareholder elects to participate in the Dividend Reinvestment and Share Purchase Plan. TO OUR SHAREHOLDERS April 30, 2003 We are pleased to present the March 31, 2003 Quarterly Report of MassMutual Corporate Investors (the "Trust"). At the Trust's Annual Shareholders Meeting, which was held on April 11, 2003, Mr. Robert E. Joyal, the Trust's President for the past four years, announced his retirement as President of the Trust. The shareholders present at the meeting elected Mr. Joyal as a new Trustee for a one-year term and re-elected Stuart H. Reese and Martin T. Hart as Trustees, each for three-year terms. The shareholders also ratified the selection of Deloitte & Touche LLP as the Trust's auditors for the year ending December 31, 2003 and approved the Investment Services Contract between the Trust and David L. Babson & Company Inc. ("Babson"). The detailed results of the shareholder voting can be found at footnote number six of the Trust's financial statements. The Board of Trustees elected me, Roger W. Crandall, to succeed Mr. Joyal as President of the Trust at their April 11, 2003 meeting. I am currently the head of the Corporate Securities Group at Babson where I oversee all corporate credit related investments, including public and private bonds, bank loans, mezzanine and private equity investments, as well as structured credit products. Prior to moving over to Babson in 2000, I spent a dozen years in the investment management area at Massachusetts Mutual Life Insurance Company, Babson's parent company. I look forward to serving as President of the Trust. The Board of Trustees declared a quarterly dividend of 36 cents per share, payable on May 15, 2003 to shareholders of record on May 2, 2003. A dividend of 36 cents per share was paid in the previous quarter. Among the many economic issues facing the Trust's investment markets, the U.S. led war with Iraq continues to loom over the U.S. economy, injecting continued uncertainty into the economic environment. During the quarter, the Dow Jones Industrial Average Index decreased 3.63%, the S&P 500 Index decreased 3.16%, and the Russell 2000 Stock Index decreased 4.49%. Conversely, the fixed income markets, especially the high yield markets, posted positive increases for the quarter ended March 31, 2003. The Merrill Lynch High Yield Master II Index increased 7.14% and the Lehman Government/Credit Index increased 1.65% for the quarter. The Trust earned 34 cents per share of net investment income for the quarter ended March 31, 2003, compared to 31 cents per share in the previous quarter. During the quarter, net assets of the Trust increased to $180,197,951 or $20.39 per share compared to $171,028,431 or $19.40 per share on December 31, 2002. This translated into a 5.10% portfolio return for the quarter, based on the change in net assets (assuming reinvestment of all dividends and distributions). Long term, the Trust's portfolio returned 7.64%, 13.94%, and 14.37% for the 5-, 10- and 25-year time periods ended March 31, 2003, respectively, again based on change in net assets with reinvestment of all dividends and distributions. During the quarter, the Trust made two new private placement investments and three follow-on investments, totaling approximately $3.7 million. The two new issuers the Trust invested in were Neff Motivation, Inc. and Weasler Holdings, LLC. The follow-on investments purchased by the Trust were in securities of Evans Consoles, Inc., Olympic Sales, Inc. and Shelter Acquisition, Inc. The weighted average coupon of these investments was 12.7%. (A brief description of these investments can be found in the Schedule of Investments.) Thank you for your continued interest in and support of MassMutual Corporate Investors. Sincerely, /s/ Roger W. Crandall Roger W.

HISTORY MassMutual Corporate Investors (the "Trust") commenced operations in 1971 as a Delaware corporation. Pursuant to an Agreement and Plan of Reorganization dated November 14, 1985, approved by shareholders, the Trust was organized as a Massachusetts business trust under the laws of the Commonwealth of Massachusetts, effective November 28, 1985. The Trust is a non-diversified closed-end management investment company. David L. Babson & Company Inc. ("Babson"), a majority owned subsidiary of Massachusetts Mutual Life Insurance Company, ("MassMutual"), acts as its investment adviser. The Trust's investment objective is to maintain a portfolio of securities providing a fixed yield and at the same time offering an opportunity for capital gains. On January 27,1998, the Board of Trustees authorized the formation of a wholly-owned subsidiary ("MMCI Subsidiary Trust") for the purpose of holding certain investments. The MMCI Subsidiary Trust's results of operations have been included in the accompanying consolidated financial statements. 2. SIGNIFICANT ACCOUNTING POLICIES The following is a summary of significant accounting policies followed consistently by the Trust in the preparation of the consolidated financial statements in conformity with accounting principles generally accepted in the United States of America. A. VALUATION OF INVESTMENTS: Valuation of a security in the Trust's portfolio is made on the basis of market price whenever market quotations are readily available and all securities of the same class held by the Trust can be readily sold in such market. Nearly all securities which are acquired by the Trust directly from the issuers and shares into which such securities may be converted or which may be purchased on the exercise of warrants attached to such securities will be subject to legal or contractual delays in or restrictions on resale and will therefore be "restricted securities". Generally speaking, as contrasted with open-market sales of unrestricted securities which may be effected immediately if the market is adequate, restricted securities can be sold only in a directly negotiated transaction to a limited number of purchasers or in a public offering for which a registration statement is in effect under the Securities Act of 1933. The value of restricted securities, and of any other assets for which there are no reliable market quotations, is the fair value as determined in good faith by the Board of Trustees of the Trust (the "Trustees"). Each restricted security is valued by the Trustees at the time of the acquisition thereof and at least quarterly thereafter. The Trustees have established guidelines to aid in the valuation of each security. Generally, restricted securities are initially valued at cost or less at the time of acquisition by the Trust. Values greater or less than cost are used thereafter for restricted securities in appropriate circumstances. Among the factors ordinarily considered are the existence of restrictions upon the sale of the security by the Trust; an estimate of the existence and extent of a market for the security; the extent of any discount at which the security was acquired; the estimated period of time during which the security will not be freely marketable; the estimated expenses of registering or otherwise qualifying the security for public sale; estimated underwriting commissions if underwriting would be required to effect a sale; in the case of a convertible security, whether or not it would trade on the basis of its stock equivalent; in the case of a debt obligation which would trade independently of any equity equivalent, the current yields on comparable securities; the estimated amount of the floating supply of such securities available; the proportion of the issue held by the Trust; changes in the financial condition and prospects of the issuer; the existence of merger proposals or tender offers affecting the issuer; and any other factors affecting fair value, all in accordance with the Investment Company Act of 1940. In making valuations, opinions of counsel may be relied upon as to whether or not securities are restricted securities and as to the legal requirements for public sale. -------------------------------------------------------------------------------- 27 NOTES TO CONSOLIDATED FINANCIAL STATEMENTS MASSMUTUAL CORPORATE INVESTORS (Continued) When market quotations are readily available for unrestricted securities of an issuer, restricted securities of the same class are generally valued at a discount from the market price of such unrestricted securities. The Trustees, however, consider all factors in fixing any discount, including the filing of a registration statement for such securities under the Securities Act of 1933 and any other developments which are likely to increase the probability that the securities may be publicly sold by the Trust without restriction. The Board of Trustees of the Trust meets at least once in each quarter to value the Trust's portfolio securities as of the close of business on the last business day of the preceding quarter. This valuation requires the approval of a majority of the Trustees of the Trust, including a majority of the Trustees who are not interested persons of the Trust (otherwise than as Trustees) or of Babson. In making valuations, the Trustees will consider reports by Babson analyzing each portfolio security in accordance with the relevant factors referred to above. Babson has agreed to provide such reports to the Trust at least quarterly. The financial statements include restricted securities valued at $164,434,542 (91.25% of net assets) as of March 31, 2003 ($166,387,779 at March 31, 2002) whose values have been estimated by the Board of Trustees in the absence of readily ascertainable market values. Due to the inherent uncertainty of valuation, those estimated values may differ significantly from the values that would have been used had a ready market for the securities existed, and the differences could be material. The values for corporate public securities are stated at the last reported sales price or at prices based upon quotations obtained from brokers and dealers as of March 31, 2003, subject to discount where appropriate, and are approved by the Trustees. Short-term securities with more than sixty days to maturity are valued at fair value and short-term securities having a maturity of sixty days or less are valued at amortized cost which approximates market value. B. ACCOUNTING FOR INVESTMENTS: Investment transactions are accounted for on the trade date. Dividend income is recorded on the ex-dividend date. Interest income is recorded on the accrual basis. The Trust has elected to accrue, for financial reporting purposes, certain premiums and discounts which are required to be accrued for federal income tax purposes. Realized gains and losses on investment transactions and unrealized appreciation and depreciation of investments are reported for financial statement and federal income tax purposes on the identified cost method. The Trust does not accrue income when payment is delinquent and when management believes payment is questionable. C. USE OF ESTIMATES: The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. -------------------------------------------------------------------------------- 28 NOTES TO CONSOLIDATED FINANCIAL STATEMENTS MASSMUTUAL CORPORATE INVESTORS (CONTINUED) D. FEDERAL INCOME TAXES: No provision for federal taxes on net investment income and short-term capital gains is considered necessary because the Trust has elected to be taxed as a "regulated investment company" under the Internal Revenue Code, and intends to maintain this qualification and to distribute substantially all of its net taxable income to its shareholders. In any year when net long-term capital gains are realized by the Trust, management, after evaluating the prevailing economic conditions, will recommend to the Trustees either to designate the net realized long-term gains as undistributed and to pay the federal capital gains taxes thereon or to distribute all or a portion of such net gains. 3. INVESTMENT SERVICES FEE Under an Investment Services Contract with the Trust, Babson has agreed to use its best efforts to present to the Trust a continuing and suitable investment program consistent with the investment objective and policies of the Trust. Babson has further agreed that it will request each issuer of securities which MassMutual is prepared to purchase in a private placement, and which would be consistent with the investment policies of the Trust, to offer such securities also to the Trust and that it will use its best efforts to insure that such request is acceded to. MassMutual has agreed that, subject to such orders of the Securities and Exchange Commission as may apply, it will invest concurrently with the Trust in any such investment. Babson will also represent the Trust in any negotiations with issuers, investment banking firms, securities brokers or dealers and other institutions or investors relating to the Trust's investments. Under the contract, Babson is obligated to provide administration of the day-to-day operations of the Trust and to provide the Trust with office space and office equipment, accounting and bookkeeping services, and necessary executive, clerical and secretarial personnel for the performance of the foregoing services. Under the investment services contract, as amended July 1, 1988, the Trust pays Babson a quarterly base rate (the "Base Fee Rate") of 5/16 of 1% of the value of the Trust's net assets as of the end of each fiscal quarter, approximately equivalent to 1.25% of the net asset value of the Trust on an annual basis, plus or minus a quarterly performance adjustment (the "Performance Adjustment") of up to 1/16 of 1% approximately equivalent to .25% on an annual basis. The Performance Adjustment is based on the Trust's performance as compared to a benchmark rate of return (the "Target Rate") equal to 5.0 percentage points plus an unweighted, arithmetic average of the rates of return on the Standard & Poor's Industrial Stock Price Index and the Lehman Brothers Intermediate Credit Bond Index (formerly called the Lehman Brothers Intermediate Corporate Bond Index) over a rolling three-year period (the "Measurement Period") comprising the twelve quarters ending on the last day of each quarter (the "Valuation Date"). The Performance Adjustment is equal to 5% of the difference between the Trust's actual rate of return over the Measurement Period and the Target Rate. If the Trust's actual rate of return exceeds the Target Rate, the Base Fee Rate is increased by an amount equal to the Performance Adjustment; if the Trust's actual rate of return is less than the Target Rate, the Base Fee Rate is reduced by the Performance Adjustment. The advisory fee payable by the Trust is equal to the Base Fee Rate (as adjusted by the Performance Adjustment) times the net asset value of the Trust as of the Valuation Date. The Performance Adjustment for the quarter ended March 31, 2003 was: PERFORMANCE ADJUSTMENT AMOUNT ---------- ------ March 31, 2003 0.0625% $113,048 -------------------------------------------------------------------------------- 29 NOTES TO CONSOLIDATED FINANCIAL STATEMENTS MASSMUTUAL CORPORATE INVESTORS (CONTINUED) 4. SENIOR SECURED INDEBTEDNESS A. NOTE PAYABLE MassMutual holds the Trust's $20,000,000 Senior Fixed Rate Convertible Note (the "Note") issued by the Trust in 1995. The Note, as amended, is due November 15, 2007 and accrues at 7.39% per annum. MassMutual, at its option, can convert the principal amount of the Note into common shares. The dollar amount of principal would be converted into an equivalent dollar amount of common shares based upon the average price of the common shares for ten business days prior to the notice of conversion. For each of the periods ended March 31, 2003 and 2002, the Trust incurred total interest expense on the Note of $369,500. The Trust may redeem the Note, in whole or in part, at the principal amount proposed to be redeemed together with the accrued and unpaid interest thereon through the redemption date plus the Make Whole Premium. The Make Whole Premium equals the excess of (i) the present value of the scheduled payments of principal and interest which the Trust would have paid but for the proposed redemption, discounted at the rate of interest of U.S. Treasury obligations whose maturity approximates that of the Note plus 0.50% over (ii) the principal of the Notes proposed to be redeemed. B. REVOLVING CREDIT AGREEMENT The Trust entered into a Revolving Credit Agreement with Fleet National Bank as of June 29, 2000, in the principal amount of $25,000,000, maturing on May 31, 2005. The interest rate on the outstanding revolving loan is determined for periods of one, three or six months (as selected by the Trust) and is set at an annual rate equal to LIBOR (London Interbank Offered Rate) plus 0.37%. The Trust also agreed to pay an up-front fee equal to 0.10% on the total commitment. The facility fee is 0.15% per annum of the total commitment. As of March 31, 2003 and 2002, there were no outstanding loans drawn against the revolving credit facility. For each of the periods ended March 31, 2003 and 2002, the Trust incurred $9,246 and $8,836, respectively, in expense related to the undrawn portion. 5.

CONTINGENCIES The Trust, together with other investors including MassMutual, is a plaintiff in two lawsuits in connection with private placement investments made by the Trust in Sharp International Corporation ("Sharp"). Three managing shareholders of Sharp, which is currently being liquidated in Chapter 7 liquidation proceedings, have pleaded guilty to criminal fraud charges. Two separate civil lawsuits were brought in New York state court in an attempt to recover damages for lost investment funds from Sharp's working capital lender and auditors. The lawsuit involving Sharp's working capital lender has been dismissed prior to trial. An appeal of this dismissal is pending. The lawsuit against Sharp's auditor is in its preliminary stages. The Trust is unable to estimate any potential recovery from these lawsuits. -------------------------------------------------------------------------------- 31 TRUSTEES OFFICERS DONALD E.

COMPTROLLER *MEMBER OF THE AUDIT COMMITTEE DIVIDEND REINVESTMENT AND SHARE PURCHASE PLAN MassMutual Corporate Investors offers a Dividend Reinvestment and Share Purchase Plan. The Plan provides a simple way for shareholders to add to their holdings in the Trust through the receipt of dividend shares issued by the Trust or through the reinvestment of cash dividends in Trust shares purchased in the open market. A shareholder may join the Plan by filling out and mailing an authorization card to Shareholder Financial Services, Inc., the Transfer Agent. Participating shareholders will continue to participate until they notify the Transfer Agent, in writing, of their desire to terminate participation. Unless a shareholder elects to participate in the Plan, he or she will, in effect, have elected to receive dividends and distributions in cash. Participating shareholders may also make additional contributions to the Plan from their own funds. Such contributions may be made by personal check or other means in an amount not less than $10 nor more than $5,000 per quarter. Whenever the Trust declares a dividend payable in cash or shares, the Transfer Agent, acting on behalf of each participating shareholder, will take the dividend in shares only if the net asset value is lower than the market price plus an estimated brokerage commission as of the close of business on the valuation day. The valuation day is the last day preceding the day of dividend payment. When the dividend is to be taken in shares, the number of shares to be received is determined by dividing the cash dividend by the net asset value as of the close of business on the valuation date or, if greater than net asset value, 95% of the closing share price. If the net asset value of the shares is higher than the market value plus an estimated commission, the Transfer Agent, consistent with obtaining the best price and execution, will buy shares on the open market at current prices promptly after the dividend payment date. The reinvestment of dividends does not, in any way, relieve participating shareholders of any federal, state or local tax. For federal income tax purposes, the amount reportable in respect of a dividend received in newly-issued shares of the Trust will be the fair market value of the shares received, which will be reportable as ordinary income and/or capital gains. As compensation for its services, the Transfer Agent receives a fee of 5% of any dividend and cash contribution (in no event in excess of $2.50 per distribution per shareholder.)
