MassMutual Corporate Investors 2001 Annual Report G R O W T H S T R E N G T H D I V E R S I T Y [LOGO] MassMutual Corporate Investors Investment Objective and Policy 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 principal investments are long-term corporate debt obligations and occasionally preferred stocks purchased directly from issuers. These provide a fixed yield and potential capital gains through warrants, conversion rights, or other equity features which are a prerequisite to every private placement purchased. The Trust holds investments in a number of companies that are not publicly traded at this time. Capital gains may be realized on holdings of private companies through various methods, including directly negotiated sales, put options and initial public offerings of stock. The Trust is managed on a total return basis. Based on change in net asset value with reinvested dividends, the Trust was ranked #1 for the five- and ten-year periods (out of 297 and 147 funds, respectively) ended December 31, 2001 among the closed-end bond funds tracked by Lipper, Inc. Dividends are paid to shareholders quarterly in January, May, August and November. The Trust intends to distribute nearly all of its net income to shareholders each year. Dividends are paid 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 19, 2002 at 2:00 p.m. in Springfield, Massachusetts. MassMutual Corporate Investors is a closed-end investment company, [PHOTO] first offered to the public nearly 30 years ago and is listed on the New York Stock Exchange. 1 [PHOTO OF ROBERT E.

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.

This past year is one that will be imbedded in our consciousness for a great many years. In addition to the events of September 11th that touched all of our lives, 2001 was a challenging year at every level. The American economy softened through the year as unemployment rose, corporate performance was weak and the stock market continued to lose value. The Federal Reserve Board, led by Chairman Alan Greenspan, attempted to solidify the economy by lowering rates 11 times throughout the year; but their action was to no avail. By early August, the S&P 500 had already lost more than 7% for the year. The events of September 11 solidified a downturn that was already in place. On the positive side, the reduction in rates more than compensated for increasing credit concerns and resulted in the Lehman Brothers Government/Credit Bond Index increasing 8.5% in 2001. The tough market environment had a significant impact on Initial Public Offerings (IPOs). The market for IPOs was white hot in 1999 and early 2000, led by technology issues. In the year 2000, 386 companies went public, raising roughly $60 billion as a whole. But then the Internet bubble burst. A severely weakened NASDAQ soured the market for new issues in 2001. IPO activity dropped by two thirds, as only 111 companies went public in 2001. The leveraged-buyout activity dropped considerably during 2001. The number of transactions decreased by 50% to 171, representing a volume of $10 billion, which was down 75% from the previous year. The deals that closed in this market typically required more equity than in previous years, as lenders reduced the amount of leverage that they were willing to accept. The year closed with the NASDAQ down by 21.1%, the S&P 500 down 11.9% and the Dow Jones Industrial Average down 5.4% for the year. Investors heaved a collective sigh of relief, and hoped the new year would bring better news. This past year brought home to us the core investment thesis that we believe is critical to the success of the Trust: investing in companies that The Trust's total rate of return for the year, as measured by the change in the net asset value with reinvested dividends, amounted to [PHOTO] 5.9%. This compares favorably to the average of the S&P 500 at a negative 11.9% and the Lehman Brothers Government/Credit Bond Index at 8.5%. 3 Total Annual Return (as of 12/31 each year) 1997 1998 1999 2000 2001 ---- ---- ---- ---- ---- MassMutual 27.14 17.12 7.53 7.28 5.91 Corporate Investors (Based on earnings and change in net asset value) S&P Industrial 31.04 33.77 25.89 -16.26 -11.67 Index Lehman Brothers 9.75 9.46 -2.15 11.84 8.50 Government/Credit Bond Index* *Formerly Lehman Brothers Government/Corporate Bond Index [PHOTO OF STEPHEN L.

McCobb, CFA, Vice President and Chief Financial Officer offer a strong fundamental business proposition, that demonstrate good cash flow, and are managed by people of high ethics who are talented, experienced managers. We look to invest in the everyday products and services that will always be important, regardless of the economic climate. Over time, we expect the Trust's return to be positioned in-between the returns that are produced by the bond and stock markets. The Trust's total rate of return for the year, as measured by the change in the net asset value with reinvested dividends, amounted to 5.9%. This compares favorably to the average of the S&P 500 at a negative 11.9% and the Lehman Brothers Government/Credit Bond Index at 8.5%. The Trust's total net assets amounted to $175.1 million at the end of 2001. Dividends totaling $1.88 per share ($.47 per quarter) were distributed during the year. The net asset value per share decreased from $20.74 in 2000 to $20.07 in 2001. While the Trust was able to maintain its $.47 per share quarterly dividend throughout the year, the current dividend level may not be sustainable in 2002. The current normalized quarterly earnings of the Trust are approximately $.40 per share. The decline in earnings is generally attributable to the recent economic environment, which resulted in both a continued decline in interest rates and recessionary conditions adversely impacting the ability of some borrowers to pay their obligations. Portfolio earnings are unlikely to rebound to the $.47 per share level in the near future. This dividend has been maintained in current quarters by the distribution of short-term capital gains, which cannot necessarily be counted on to sustain future distributions. This past year brought home to us the core investment thesis that we believe is critical to the success of the Trust: investing in [PHOTO] companies that offer a strong fundamental business proposition, that demonstrate good cash flow, and are managed by people of high ethics who are talented, experienced managers. 4 MassMutual Corporate Investors Overall, the Trust closed 13 deals in 2001, including 9 new investments and 4 additions to current positions. Among the new holdings in the portfolio: o Coining Corporation of America, a manufacturer of close tolerance parts and metal stampings. o Dexter Magnetics Technologies, Inc., a designer, fabricator, assembler and distributor of industrial magnets and subassemblies in North America and Europe. o DHD Healthcare, Inc., a designer, manufacturer and distributor of plastic, non-invasive medical devices used for respiratory care. o Kenan-Advantage Transport Company, a transporter of light petroleum, petrochemicals, lubricants and residual fuels. o PGT Industries, a manufacturer of residential windows and patio doors and a provider of custom patio rooms and porch enclosures. You will find details of all the Trust's holdings in the Consolidated Schedule of Investments.

Morrison 5 Preview of 2002 Although the current economic environment remains challenging, we believe that this is an opportune time to invest for the future. As an example, one of the types of investments that the Trust makes consists of Senior or Subordinated Notes issued by companies that are being purchased in a leveraged-buyout. Leveraged-buyout opportunities have become significantly more conservative during the past year, as sponsors have been required to contribute a higher percentage of equity to the deal resulting in less leverage to the Senior and Subordinated Notes. The Trust will continue its disciplined approach of focusing on investing in companies that offer good value on a risk-adjusted basis. We believe that our investment approach has provided solid returns in the past and is particularly well suited to do so in this unsettled future.

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 consolidated in the accompanying 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 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 $165,049,591 (94.25% of net assets) as of December 31, 2001 ($176,899,997 at December 31, 2000) 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, 2001, 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, 2001 AND 2000 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 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. In 2001, the Trust reclassed ($32,035) 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. MANAGEMENT FEE Under an investment services contract, Babson has agreed to invest for MassMutual's 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, safekeeping facilities, 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, 2001 was: Performance Adjustment Amount -------------------------------------------------------------------------------- March 31, 2001 0.0625% $ 113,989 June 30, 2001 0.0625% 115,719 September 30, 2001 0.0625% 111,324 December 31, 2001 0.0625% 109,737 -------------------------------------------------------------------------------- Total 0.2500% $ 450,769 A. Note Payable: On November 5, 1993, the Trust sold to MassMutual at par a $20,000,000 Senior Fixed Rate Convertible Note due November 15, 2000 (the "Note") which accrues at 5.33% per annum. The Note holder, 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. In agreement with MassMutual, the Note's maturity has been extended for an additional seven years from November 15, 2000. The Note is due November 15, 2007 and will accrue at 7.39% per annum. For each of the years ended December 31, 2001 and 2000, the Trust incurred total interest expense on the Note of $1,478,000 and $1,117,500, respectively. 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 December 31, 2001 and 2001, there were no outstanding loans drawn against the revolving credit facility. For the period ended December 31, 2001 and 2000, the Trust incurred $37,397 and $19,007 in expense related to the undrawn portion. 34 MassMutual Corporate Investors Notes to Consolidated Financial Statements DECEMBER 31, 2001 AND 2000 5.

Norgaard* Dean, Barney School of Business and Public Administration, University of Hartford *Member of Audit Committee 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"), including the consolidated schedule of investments, as of December 31, 2001 and 2000, and the related consolidated statements of operations, cash flows, changes in net assets, and the consolidated financial highlights for the years then ended. These financial statements and financial highlights are the responsibility of the Trust's management. Our responsibility is to express an opinion on these financial statements based on our audits. The financial highlights for the year ended December 31, 1998 and for each of the years in the seven-year period then ended were audited by other auditors, whose report, dated February 25, 1999 expressed an unqualified opinion on those 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 financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements and financial highlights. Our procedures included confirmation of securities owned as of December 31, 2001 by corre-spondence with the custodians and brokers. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion. In our opinion, the consolidated financial statements and consolidated financial highlights referred to above present fairly, in all material respects, the financial position of the Trust as of December 31, 2001 and 2000, and the results of its operations, its cash flows, changes in net assets, and financial highlights for the years then ended in conformity with accounting principles generally accepted in the United States of America. /s/ Deliotte & Touche LLP ------------------------------- New York, New York February 8, 2002 [PHOTO OF STUART H.

Hart, Richard G. Dooley, Jack A. Laughery, Milton Cooper, Donald Glickman 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 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).
