New York, NY 10043 MCI Listed NYSE MASSMUTUAL CORPORATE INVESTORS 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. In this report you will find a complete listing of the Trust's holdings. We encourage you to read this section carefully for a better understanding of the Trust. We cordially invite all shareholders to attend the MassMutual Corporate Investors Annual Meeting of Shareholders, which will be held on April 11, 2003 at 2:00 P.M. in Springfield, Massachusetts.

Past performance is no indicator of future results. 2 The S&P Industrial Index is a capitalization-weighted index of stocks designed to measure the performance of the industrial sector of the Standard and Poor's 500 Index(R) (the S&P 500 Index(R) minus financials, utilities and transportation stocks). The index does not incur expenses and cannot be purchased directly by investors. 3 The Lehman Brothers Government/Credit Bond Index (formerly Lehman Brothers Government/Corporate Bond Index) is an unmanaged measure of major U.S. Government and investment grade corporate bonds with more than one year remaining until the scheduled payment of principal. The index does not incur expenses and cannot be purchased directly by investors. -2- MASSMUTUAL CORPORATE INVESTORS TO OUR SHAREHOLDERS ------------------------------------------ I am pleased to share with you MassMutual Corporate Investors' (the "Trust") Annual Report covering the year ended December 31, 2002. This past year was, once again, a challenging one at all levels. The economy was soft, as corporate and accounting scandals ran rampant, unemployment rose and concerns about additional terrorism or possible war in the Middle East affected the market's performance. Investor confidence was down, as the S&P 500 declined for the third year in a row and the fixed income market suffered a large number of defaults and a record number of credit downgrades. Interest rates were the lowest we had seen in nearly 40 years. These challenging factors added up to create seemingly endless volatility and a most difficult environment for the small to mid-sized companies in which the Trust traditionally invests. The year closed with the S&P 500 Index down 22.10%, the NASDAQ down 31.13% and the Dow Jones Industrial Average down 14.98% for the year. On a positive note, inflation continued to be low, as did interest rates. The low rates helped the Lehman Brothers Government/Credit Bond Index achieve an increase of 11.04% for the year. The economy continued to affect Initial Public Offering (IPO) activity throughout 2002, as it did in 2001. IPO volume numbered just 83 deals,* a two-decade low, due to skepticism that new offerings would generate strong earnings in such a difficult market. The third quarter in particular experienced little action, with only seven companies brought to the public market, the lowest number of new offerings in a quarter in twenty-two years. The first half of the year was also quiet for leveraged buyouts. However, because valuations were low, the buyout market sat ready for an increase in activity. We started to see this increase during the fourth quarter and we expect that increased deal flow will continue into 2003. *Source: The Wall Street Journal, January 2, 2003. The Trust ended the year with an annual total rate of return of 4.80%, as measured by the change in the net asset value with reinvested dividends. These results compare favorably to the average of the S&P 500 Index at negative 22.10% and the Lehman Brothers Government/Credit Bond Index at a positive 11.04%. -3- [PHOTO] LEFT TO RIGHT: Clifford M. Noreen, Vice President, Roger W. Crandall, CFA, Vice President, Stephen L. Kuhn, Vice President and Secretary, Charles C. McCobb, CFA, Vice President and Chief Financial Officer -------------------------------------------------------------------------------- Although 2002 was a particularly difficult year, it was not unlike the early 1990's, when we saw a major downturn followed by a decade of growth in the economy and the Trust. Our experience through other challenging times shows us the way - and brings home to us the fundamental beliefs with which we manage the Trust on a daily basis. We believe in dealing with ethical, professional people who are committed to success. We believe in investing in companies with a strong business proposition, good cash flow and talented, experienced management and we believe in diversifying our investments over a wide range of industries and issuers. These beliefs and our goals for the Trust do not change with the economic environment, but enable us to select the best investments available in order to take advantage of future market potential. We believe the current market presents an excellent opportunity for us to build the strength of the Trust, and position it for continued success in the future. The Trust ended the year with an annual total rate of return of 4.80%, as measured by the change in the net asset value with reinvested dividends. These results compare favorably to the average of the S&P 500 Index at negative 22.10% and the Lehman Brothers Government/Credit Bond Index at a positive 11.04%. The Trust's total net assets as of the end of 2002 were $171,028,431. Although the Trust continued to report good relative performance, the Board of Trustees did find it necessary to reduce the quarterly dividend to 36 cents per share to bring it more in line with the current earnings level of the portfolio. The net asset value per share of the Trust decreased slightly in 2002 to $19.40 from $20.07 at December 31, 2001.

You will find details of all the Trust's holdings in the Consolidated Schedule of Investments. Although we see signs that the economy is improving, we do not believe that a dramatic change will take place over the next twelve months. In the meantime, the Trust will continue to look at the current economic environment as an opportune time to invest. -5- MASSMUTUAL CORPORATE INVESTORS THE OUTLOOK FOR 2003 ------------------------------------------ Although we see signs that the economy is improving, we do not believe that a dramatic change will take place over the next twelve months. In the meantime, the Trust will continue to look at the current economic environment as an opportune time to invest. Prices are attractive and leverage is lower leading to issuers having more conservative capital structures. By following our fundamental beliefs and continuing our disciplined approach to investing, we believe that the Trust is well-positioned to take advantage of a future upturn in the economy.

HISTORY MassMutual Corporate Investors (the "Trust") is a closed-end, non-diversified 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 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. 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 results of MMCI Subsidiary Trust 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. 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 $162,254,000 (94.87% of net assets) as of December 31, 2002 ($165,049,591 at December 31, 2001) 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 December 31, 2002, 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 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. -33- MASSMUTUAL CORPORATE INVESTORS NOTES TO CONSOLIDATED FINANCIAL STATEMENTS DECEMBER 31, 2002 AND 2001 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. 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 longterm 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. In 2002, the Trust reclassed ($68,784) from undistributed net investment income to additional paid-in-capital to more accurately portray the Trust's financial position. This reclass has no impact on the Trust's net asset value per share. E. RECLASSIFICATIONS Certain amounts from prior years' financial statements have been reclassed to conform with current year presentation. 3. INVESTMENT ADVISORY FEE Under an investment services contract, Babson has agreed to invest for MassMutual general account concurrently with the Trust in each restricted security purchased by the Trust. Babson, in addition to originating and sharing in the purchase of such securities, represents 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. Babson provides a continuing review of the investment operations of the Trust. Babson also provides 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 quarters ended March 31, June 30, September 30 and December 31, 2002 was: Performance Adjustment Amount ---------- ------ March 31, 2002 0.0625% $114,090 June 30, 2002 0.0625% $112,914 September 30, 2002 0.0625% $108,793 December 31, 2002 0.0625% $107,295 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 years ended December 31, 2002 and 2001, the Trust incurred total interest expense on the Note of $1,478,000. B. REVOLVING CREDIT AGREEMENT The Trust entered into a Revolving Credit Agreement (the "Revolver") 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 December 31, 2002 and 2001, there were no outstanding loans drawn against the Revolver. For each of the years ended December 31, 2002 and 2001, the Trust incurred $37,500 and $37,397, respectively, in expense related to the undrawn portion. -34- MASSMUTUAL CORPORATE INVESTORS DECEMBER 31, 2002 AND 2001 Notes to Consolidated Financial Statements 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 have been 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 Trust is unable to estimate any potential recovery from these lawsuits as of February 7, 2003. -35- MASSMUTUAL PARTICIPATION INVESTORS INTERESTED TRUSTEES NAME (AGE), ADDRESS, PRINCIPAL OCCUPATION SERVICE BEGAN/ POSITION WITH THE TRUST DURING THE PAST FIVE YEARS/OTHER DIRECTORSHIPS HELD TERM ENDS -------------------------------------------------------------------------------------------------- STUART H.

Springfield, MA 01115 Comptroller -39- INDEPENDENT AUDITORS' REPORT ------------------------------------------ To the Shareholders and the Board of Trustees of MassMutual Corporate Investors We have audited the accompanying consolidated statements of assets and liabilities of MassMutual Corporate Investors (the "Trust") as of December 31, 2002 and 2001 (including the consolidated schedule of investments as of December 31, 2002), and the related consolidated statements of operations, cash flows, changes in net assets for the two years then ended and the consolidated selected financial highlights for the four-year period ended December 31, 2002. These consolidated financial statements and consolidated selected financial highlights are the responsibility of the Trust's management. Our responsibility is to express an opinion on these consolidated financial statements and consolidated selected financial highlights based on our audits. The consolidated selected financial highlights for the year ended December 31, 1998 and for each of the years in the six-year period then ended were audited by other auditors, whose report, dated February 25, 1999 expressed an unqualified opinion on those consolidated selected financial highlights. We conducted our audits in accordance with auditing standards generally accepted in the United States of America. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements and consolidated selected financial highlights are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the consolidated financial statements. Our procedures included verification of securities owned as of December 31, 2002, by counting of securities at the custodian and confirmation of securities owned as of December 31, 2002 by correspondence with the custodian and brokers. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall consolidated financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the consolidated financial statements and consolidated selected financial highlights referred to above present fairly, in all material respects, the financial position of the Trust as of December 31, 2002 and 2001, and the results of its operations, its cash flows, changes in net assets for the two years then ended, and consolidated selected financial highlights for the four-year period ended December 31, 2002, in conformity with accounting principles generally accepted in the United States of America.

Dooley, Retired Executive Vice President and Chief Investment Officer, Massachusetts Mutual Life Insurance Company -------------------------------------------------------------------------------- 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.) Any questions regarding the Plan should be addressed to Shareholder Financial Services, Inc., Agent for MassMutual Corporate Investors' Dividend Reinvestment and Share Purchase Plan, P.O.
