MassMutual Participation Investors Investment Objective and Policy MassMutual Participation Investors (the "Trust") is a closed-end investment company, first offered to the public in 1988, whose shares are traded on the New York Stock Exchange under the trading symbol "MPV". The Trust's share price can be found in the financial section of most newspapers as "MassPrt" or "MassMuPrt" under the New York Stock Exchange listings. [PIE CHART APPEARS HERE] Portfolio Composition as of 12/31/04* Public High Yield Debt 24% Private Investment Grade Debt 1% Cash & Short Term Investments 7% Private/Restricted Equity 14% Public Equity 2% Private High Yield Debt 52% *Based on value of total investments The Trust's investment objective is to maximize total return by providing a high level of current income, the potential for growth of income, and capital appreciation. The Trust's principal investments are privately placed, below-investment grade, long-term corporate debt obligations purchased directly from their issuers, which tend to be smaller companies. At least half of these investments normally include equity features such as warrants, conversion rights, or other equity features that provide the Trust with the opportunity to realize capital gains. The Trust will also invest in publicly traded debt securities (including high yield securities), again with an emphasis on those with equity features, and in convertible preferred stocks and, subject to certain limitations, readily marketable equity securities. In addition, the Trust may temporarily invest in high quality, readily marketable securities. Babson Capital Management LLC 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. All registered shareholders are automatically enrolled in the Dividend Reinvestment and Cash Purchase Plan unless cash distributions are requested. 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 Participation Investors Annual Meeting of Shareholders, which will be held on April 22, 2005 at 1:00 P.M. in Springfield, Massachusetts. 1 MassMutual Participation Investors To Our Shareholders On July 1, 2004, David L. Babson & Company Inc., the investment adviser to MassMutual Participation Investors (the "Trust"), announced that it was renaming itself as Babson Capital Management LLC. The Trust continues to be managed by the same individuals and there should be no change in the level of service provided. I am pleased to share with you the Trust's Annual Report for the year ended December 31, 2004. [PHOTO APPEARS HERE] Left to right: Roger W. Crandall President Stuart H.

[PHOTO APPEARS HERE] Left to right: Stephen L. Kuhn Vice President and Secretary Clifford M. Noreen Vice President Charles C. McCobb, Jr. Vice President and Chief Financial Officer The Trust continues to repeatedly employ the investment philosophy that has served it well since its inception: investing in companies which we believe to have a strong business proposition, solid cash flow and experienced, ethical management. 3 MassMutual Participation Investors The Trust's 2004 Portfolio Performance The Trust's total portfolio rate of return for 2004 was 25.14%, as measured by the change in net asset value, assuming the reinvestment of all dividends and distributions. The Trust's total net assets were $107,610,007, or $11.13 per share, as of December 31, 2004, compared to $94,396,591, or $9.84 per share, as of December 31, 2003. The Trust's quarterly per-share dividend increased in the first and second quarters of 2004 and remained stable for each of the next two quarters of 2004: from 20 cents per share paid for each quarter in 2003 to 21 cents per share paid in May, to 24 cents per share paid in August and in November. While the regular fourth quarter dividend paid in January remained at 24 cents per share, the Trust declared a special year-end dividend of 12 cents per share paid in January to shareholders of record on December 31, 2004. Aspecial 5 cent per share dividend was also paid in August, bringing total dividends for the year to $1.10 per share. All in all, we are very pleased with the Trust's 2004 portfolio performance.

The above table lists the average annual returns of the Trust's portfolio, based on change in net assets, assuming the reinvestment of all dividends and distributions, compared to the average annual returns of selected equity and fixed income market indices for the 1, 3, 5 and 10 years ended December 31, 2004. The U.S. economy and investment markets showed surprising resilience in 2004, holding steady despite several factors: short-term interest rates were raised five times during the year by the Federal Reserve Board for a total increase of 1.25 percent; oil reaching a record high price of $50 a barrel; a weakening dollar; the worst hurricane season in 40 years; the ongoing war in Iraq; and a highly charged Presidential election campaign. 4 MassMutual Participation Investors While historically events such as these have had a negative economic impact, indications are that the U.S. economy continues to improve. U.S. Gross Domestic Product grew at a 4.4 percent rate for the year and the unemployment rate dropped to 5.4 percent from 5.7 percent. Nevertheless, at the close of 2004, both the Dow Jones Industrial Average and the Standard & Poor's 500 Index were at their highest levels since pre-September 11, 2001. Corporate credit defaults around the globe continued their downward trend (although possibly plateauing at year-end), which provided a more stable environment for investors. In the U.S., the speculative-grade issuer-weighted default rate fell to 2.2% at year-end from a starting point of 5.2% in 2003, as reported by Moody's Investors Service. Meanwhile, 2004 saw dollardenominated high-yield bond issuance approach $134.8 billion, keeping pace with the $135.7 billion issued in 2003, according to Credit Suisse First Boston. The value of mergers and acquisitions among domestic companies reached $834 billion, a tally surpassed only in the record year of 2000, according to Thompson Financial. This is an indication of the amount of capital available in the market to finance deals; however, this environment has caused the markets in which the Trust participates to become very competitive. Overall, the Trust closed 23 new private placement transactions during 2004 and added to seven existing private placement investments, a relatively large number compared with previous years. To keep pace with this activity, Babson Capital has added additional investment professionals to its mezzanine and private equity group. New private placement transactions during the year were: ATI Acquisition Company; AWC Holding Company; American Hospice Management Holding LLC; Augusta Sportswear Holding Co.; Chemed Corporation (Roto-Rooter, Inc.); Eagle Pack Pet Foods, Inc.; EXC Acquisition Corporation; Home Decor Holding Company; Justrite Manufacturing Acquisition Co.; Kele and Associates, Inc.; Maverick Acquisition Company; Maxon Corporation; Nonni's Food Company; Qualis Automotive LLC; Qualserv Corporation; River Ranch Fresh Foods LLC; Savage Sports Holding, Inc.; Sport Court International, Inc.; Tubular Textile Machinery; U-Line Corporation; Vitality Foodservice, Inc.; Vitex Packaging Group, Inc.; and Walls Industries, Inc. In addition, the Trust added to existing private placement investments in Brampton Fasteners Co. Ltd., Colibri Holdings Corp., Delstar Holding Corporation, Dwyer Group, Inc., Home Decor Holding Company, MedAssist, Inc. and Shelter Acquisition, Inc. [PHOTO APPEARS HERE] Left to right: Michael L. Klofas Vice President Richard E. Spencer, II Vice President Michael P. Hermsen Vice President 5 MassMutual Participation Investors The Outlook for 2005 For 2005, expectations are mixed. The Fed will likely continue to raise short-term rates, and many analysts believe long-term interest rates may rise as well. The global economy is focused on the budget and current account deficits in the U.S., with the risk of further dollar weakness. Oil prices will continue to have a risk premium because of instability and conflict in the Middle East. While economic indicators such as unemployment levels, manufacturing activity and consumer confidence looked promising at year-end, no one can predict the future with any degree of certainty. Stronger equity and credit markets have helped fuel increased M & Aactivity - pushing valuations toward the high end of historical ranges. The margin of safety in many investments has been reduced, requiring investors to increase the scrutiny of each opportunity. Regardless of the economic environment, however, the Trust continues to repeatedly employ the investment philosophy that has served it well since its inception: investing in companies which we believe to have a strong business proposition, solid cash flow and experienced, ethical management. This philosophy, combined with Babson Capital's seasoned investment-management team and the Trust's financial position, contribute to the Trust's being well positioned for future investment opportunities that meet its investment objectives and policies. As always, I would like to thank you for your continued interest in and support of MassMutual Participation Investors. Sincerely, /S/ Roger W. Crandall Roger W.

HISTORY MassMutual Participation Investors (the "Trust") was organized as a Massachusetts business trust under the laws of the Commonwealth of Massachusetts pursuant to a Declaration of Trust dated April 7, 1988. The Trust is a diversified closed-end management investment company. Babson Capital Management LLC, formerly David L. Babson & Company Inc. ("Babson Capital"), a wholly-owned indirect subsidiary of Massachusetts Mutual Life Insurance Company ("MassMutual"), acts as its investment adviser. The Trust's investment objective is to maximize total return by providing a high level of current income, the potential for growth of such income, and capital appreciation, by investing primarily in a portfolio of privately placed below investment grade, long-term corporate debt obligations purchased directly from their issuers, at least half of which normally will include equity features. On January 27, 1998, the Board of Trustees authorized the formation of a wholly owned subsidiary ("MMPI Subsidiary Trust") for the purpose of holding certain investments. The results of the MMPI Subsidiary Trust have been consolidated in the accompanying financial statements. Footnote 2.D below discusses the Federal tax consequences of the MMPI Subsidiary Trust. 2. SIGNIFICANT ACCOUNTING POLICIES The following is a summary of significant accounting policies followed consistently by the Trust in the preparation of its 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 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, absent an exemption from registration, restricted securities can be sold only 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 Trust's Board of Trustees (the "Trustees"). Each restricted security is valued by the Trustees as of the time of its acquisition 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 thereafter used for restricted securities in appropriate circumstances. Among the factors ordinarily considered are the existence of restrictions upon the sale of a security held by the Trust; an estimate of the existence and the 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 for purchase; 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, as amended. 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 Trust's Board of Trustees 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 or of Babson Capital, the Trust's investment adviser. In making valuations, the Trustees will consider Babson Capital's reports analyzing each portfolio security in accordance with the relevant factors referred to above. Babson Capital has agreed to provide such reports to the Trust at least quarterly. The consolidated financial statements include restricted securities valued at $86,704,953 (80.57% of net assets) as of December 31, 2004 whose values have been determined by the Board of Trustees in the absence of readily ascertainable market values. Due to the inherent uncertainty of valuation, those 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, 2004, 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. 36 MassMutual Participation Investors NOTES TO CONSOLIDATED FINANCIAL STATEMENTS DECEMBER 31, 2004 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 does not accrue income when payment is delinquent and when management believes payment is questionable. Discounts and premiums on securities purchased are amortized, over the lives of the respective securities. 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. 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 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 that Trustees either designate the net realized long-term gains as undistributed and pay the federal capital gains taxes thereon, or distribute all or a portion of such net gains. For the year ended December 31, 2004, the Trust has a net tax basis capital loss carry-forward of $1,352,300 available to offset future net realized capital gains. $841,404 and $510,896 of the loss carry-forward expires on December 31, 2010 and December 31, 2011, respectively, if not offset by net realized capital gains before the expiration dates. To the extent that such carry-forward is used by the Trust, no capital gain distributions or designation as undistributed will be made. In 2004, the Trust re-classified a total of $668,738 to undistributed net investment income. $594,934 was re-classified from accumulated net realized loss on investments and $73,804 was re-classified from additional paid in capital to more accurately display the Trust's financial position. These re-classifications had no impact on net asset value. The Trust is taxed as a regulated investment company and is therefore limited as to the amount of non-qualified income that it may receive as the result of operating a trade or business, e.g. the Trust's pro rata share of income allocable to the Trust by a partnership operating company. The Trust's violation of this limitation could result in the loss of its status as a regulated investment company, thereby subjecting all of its net income and capital gains to corporate taxes prior to distribution to its shareholders. The Trust, from time-to-time, identifies investment opportunities in the securities of entities that could cause such trade or business income to be allocable to the Trust. The MMPI Subsidiary Trust (described in Footnote 1, above) was formed in order to allow investment in such securities without adversely affecting the Trust's status as a regulated investment company. The MMPI Subsidiary Trust is not taxed as a regulated investment company. Accordingly, prior to the Trust's receiving any distributions from the MMPI Subsidiary Trust, all of the MMPI Subsidiary Trust's taxable income and realized gains, including non-qualified income and realized gains, is subject to taxation at prevailing corporate tax rates. For the year ended December 31, 2004 the MMPI Subsidiary Trust has accrued income tax expense on income and realized gains of $158,788 and $504,437, respectively. E. DISTRIBUTIONS TO SHAREHOLDERS The Trust records distributions to shareholders from net investment income and net realized gains, if any, on the exdividend date. The Trust's net investment income dividend is declared four times per year, in April, July, October and December. The Trust's net realized capital gain distribution, if any, is declared in December. The tax character of distributions paid during the years ended December 31, 2004 and 2003 were as follows: Distributions paid from: 2004 2003 ----------------------------------- Ordinary Income $10,613,225 $9,186,933 As of December 31, 2004, the components of distributable earnings on a tax basis included $471,327 of undistributed ordinary income. Such distributions and distributable earnings on a tax basis are determined in conformity with income tax regulations, which may differ from accounting principles generally accepted in the United States. Net investment income of the Trust as presented under accounting principles generally accepted in the United States differs from distributed earnings due to a distribution made from after tax earnings of the MMPI Subsidiary Trust to the Trust. The Trust treats the distribution from the MMPI Subsidiary Trust as taxable earnings. 3. INVESTMENT ADVISORY AND ADMINISTRATIVE SERVICES FEE Under an Investment Advisory and Administrative Services Contract with the Trust, Babson Capital has agreed to use its best efforts to present to the Trust a continuing and suitable investment program consistent with the investment objectives and policies of the Trust. Babson Capital 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 objectives and policies of the Trust, to also offer such securities to the Trust. Babson Capital will use its best efforts to insure that issuers accede to such requests. 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 Capital 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. Under the contract, Babson Capital provides administration of 37 MassMutual Participation Investors NOTES TO CONSOLIDATED FINANCIAL STATEMENTS DECEMBER 31, 2004 the day-to-day operations of the Trust and 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. For its services under the Investment Advisory and Administrative Services Contract, Babson Capital is paid a quarterly fee equal to .225% of the value of the Trust's net assets as of the last business day of each fiscal quarter, an amount approximately equivalent to .90% on an annual basis. Amajority of the Trustees, including a majority of the Trustees who are not interested persons of the Trust or of Babson Capital, approve the valuation of the Trust's net assets as of such day. 4. SENIOR SECURED INDEBTEDNESS: A. NOTE PAYABLE MassMutual holds the Trust's $12,000,000 Senior Fixed Rate Convertible Note (the "Note") issued by the Trust in 1995. The Note, as amended, is due December 13, 2011 and accrues interest at 5.80% 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 the year ended December 31, 2004, the Trust incurred total interest expense on the Note of $696,000. 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 a 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 $15,000,000 Revolving Credit Agreement with Fleet National Bank (the "Agent Bank") dated May 29, 1997, which had a stated matured on May 31, 2004. The maturity date of this loan was extended to May 31, 2007, and its terms amended and restated pursuant to the First Amended and Restated Revolving Credit Agreement (the "Revolver") dated May 27, 2004, between the Trust and the Agent Bank. The Revolver bears interest payable quarterly in arrears at a per annum rate that varies depending upon whether the Trust requests a Base Rate Loan or LIBOR Rate Loan. Interest on Base Rate loans equals the higher of: (i) the annual "Base Rate" as set periodically by the Agent Bank and (ii) the most recent Federal Funds Effective Rate plus .50% per annum. Per annum interest on LIBOR Rate Loans equals .60% plus the London Inter Bank Offered Rate ("LIBOR") rate, divided by 1 minus LIBOR Reserve Rate. The Trust also incurs expense on the undrawn portion of the total Revolver at a rate of .25% per annum. The Trust incurred closing costs on the Revolver of $7,500. As of December 31, 2004, there was $10,500,000 in outstanding loans against the Revolver and the average blended rate of interest attributable to the Revolver was 1.87%. For the year ended December 31, 2004, the Trust incurred total interest expense on the Revolver of $196,594, plus $10,073 related to the undrawn portion. 5.

AGGREGATE REMUNERATION PAID TO OFFICERS, TRUSTEES AND THEIR AFFILIATED PERSONS During 2004, the Trust paid its Trustees aggregate remuneration of $101,107. The Trust does not pay any compensation to any of its Trustees who are "interested persons" (as defined by the Investment Company Act of 1940, as amended [the "40 Act"]) of the Trust. Accordingly, the Trust classifies Messers. Reese and Joyal as "interested persons" of the Trust. All of the Trust's officers are employees of Babson Capital or MassMutual. Pursuant to the Investment Advisory and Administrative Services Contract, the Trust does not compensate its officers who are employees of Babson Capital or MassMutual. MassMutual and Babson Capital are "affiliated persons" (as defined by the 40 Act) of Mr. Reese, one of the Trust's Trustees. The Trust did not make any payments to Babson Capital during 2004, other than amounts payable to Babson Capital pursuant to the Investment Advisory and Administrative Services Contract.

CONTINGENCIES The Trust, together with other investors including MassMutual, is a plaintiff in litigation 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 11 liquidation proceedings, have pleaded guilty to criminal fraud charges. Initially, 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 first lawsuit involving Sharp's working capital lender was dismissed prior to trial. An appeal of this dismissal was unsuccessful. The second lawsuit against Sharp's auditors is continuing. The parties to the lawsuit, including the Trust, have submitted the matters which are the subject of the lawsuit to the non-binding mediation proceedings. The mediation proceedings were unsuccessful. The trial for this lawsuit is scheduled to begin in April 2005. The Trust is unable to estimate any potential recovery from this lawsuit as of December 31, 2004. 9. CERTIFICATIONS As required under New York Stock Exchange ("NYSE") Corporate Governance Rules, the Trust's principal executive officer has certified to the NYSE that he was not aware, as of the certification date, of any violation by the Trust of the NYSE's Corporate Governance listing standards. In addition, as required by Section 302 of the Sarbanes-Oxley Act of 2002 and related SEC rules, the Trust's principal executive and principal financial officers have made quarterly certifications, included in filings with the Securities and Exchange Commission on Forms N-CSR and N-Q, relating to, among other things, the fund's disclosure controls and procedures and internal control over financial reporting, as applicable. 39 MassMutual Participation Investors INTERESTED TRUSTEES OFFICE PORTFOLIOS POSITION TERM/LENGTH OVERSEEN OTHER WITH OF TIME PRINCIPAL OCCUPATION(S) IN FUND DIRECTORSHIPS NAME (AGE), ADDRESS THE TRUST SERVED DURING PAST 5 YEARS COMPLEX HELD BY DIRECTOR ------------------------------------------------------------------------------------------------------------------------------------ STUART H.

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 and financial highlights based on our audit. The statement of changes in net assets for the year ended December 31, 2003 and financial highlights for each of the years in the fouryear period ended December 31, 2003 were audited by the Trust's previous auditors whose report, dated February 6, 2004, expressed an unqualified opinion on that financial statement and those financial highlights. We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. Our procedures included confirmation of securities owned as of December 31, 2004, by correspondence with the custodian and brokers, or by other appropriate auditing procedures. 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 audit provides a reasonable basis for our opinion. In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of MassMutual Participation Investors as of December 31, 2004, and the results of its operations, its cash flows, the changes in its net assets, and the financial highlights for the year then ended in conformity with accounting principles generally accepted in the United States of America. /s/ KPMG LLP February 7, 2005 46 [PHOTO APPEARS HERE] MEMBERS OF THE BOARD OF TRUSTEES Donald Glickman Chairman, Donald Glickman & Company, Inc.

The Plan provides a simple and automatic 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. The dividends of each shareholder will be automatically reinvested in the Trust by Shareholder Financial Services Inc., the Transfer Agent, in accordance with the Plan, unless such shareholder elects not to participate by providing written notice to the Transfer Agent. A shareholder may terminate his or her participation by notifying the Transfer Agent in writing. 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 $100 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.)

KPMG LLP ("KPMG") was the Registrant's independent auditors for the 2004 fiscal year audit. The category "Audit Related Fees" reflects fees billed by KPMG or D&T for services related to the audit and other assurance services performed in connection with the audit engagements of the Registrant, Babson Capital Management LLC ("Babson") and Massachusetts Mutual Life Insurance Company ("MassMutual"). Preparation of Federal, state and local income tax and compliance work are representative of the fees billed in the "Tax Fees" category. The category "All Other Fees" represents fees billed by KPMG or D&T for various non-audit and non-tax services rendered to Babson and MassMutual, such as SAS 70 review, agreed upon procedures reports, and tax consulting. The Sarbanes-Oxley Act of 2002 and its implementing regulations allows the Registrant's Audit Committee to establish a pre-approval policy for certain services rendered by the Registrant's independent accountants. During 2004, the Registrant's Audit Committee approved all of the services rendered to the Registrant by KPMG and did not rely on such a pre-approval policy for any such services. The Audit Committee reviewed the aggregate fees billed for professional services rendered by KPMG for the Registrant and for the non-audit services provided to Babson, and Babson's parent, MassMutual. As part of this review, the Audit Committee considered whether the provision of such non-audit services were compatible with maintaining the principal accountant's independence. ITEM 5. AUDIT COMMITTEE OF LISTED REGISTRANTS.

DISCLOSURE OF PROXY VOTING POLICIES AND PROCEDURES FOR CLOSED END MANAGEMENT INVESTMENT COMPANIES. The Registrant's Board of Trustees delegated proxy voting responsibilities relating to voting securities held by the Registrant to its investment adviser, Babson Capital Management LLC ("Babson"). A summary of Babson's proxy voting policies and procedures is set forth below. Summary of Babson's Proxy Voting Policy --------------------------------------- Babson views the voting of proxies as an integral part of its investment management responsibility and believes, as a general principle, that proxies should be voted solely in the best interests of its clients (i.e. prudently and in a manner believed by Babson to best protect and enhance an investor's returns). To implement this general principle, it is Babson's policy to generally vote proxies in accordance with the recommendations of Institutional Shareholder Services ("ISS"), a recognized authority on proxy voting and corporate governance, or, in cases where ISS has not made any recommendations with respect to a proxy, in accordance with ISS's proxy voting guidelines. Babson recognizes, however, that there may be times when Babson believes that it will be in the best interests of clients holding the securities to (1) vote against ISS's recommendations or (2) in cases where ISS has not provided Babson with any recommendations with respect to a proxy, vote against ISS's proxy voting guidelines. Babson may vote, in whole or part, against ISS's recommendations or ISS's proxy voting guidelines, as applicable, if such vote is authorized by the Policy. The procedures set forth in the Policy are designed to ensure that votes against ISS's recommendations or proxy voting guidelines have been made in the best interests of clients and are not the result of any material conflict of interest (a "Material Conflict"). Summary of Babson's Proxy Voting Procedures ------------------------------------------- Babson has (1) established a Proxy Committee that is responsible for the implementation and governance of the Policy and (2) designated Proxy Administrators who will receive and post proxies for voting with ISS. In accordance with the Policy, Babson will generally vote all client proxies in accordance with ISS's recommendation or proxy voting guidelines, unless a person authorized by the Proxy Committee (each a "Proxy Analyst") determines that it is in its clients' best interest to vote against ISS's recommendation or proxy voting guidelines. In these cases, Babson will vote against ISS's recommendation or proxy voting guidelines, so long as no other Proxy Analyst reviewing such proxy disagrees with such recommendation, and no known Material Conflict is identified by the Proxy Analyst(s) or the Proxy Administrator. Otherwise, the proxy is to be submitted to a member of the Proxy Committee, who shall determine how to vote the proxy unless (i) the Proxy Administrator has identified a Babson Material Conflict or (ii) said Proxy Committee member has identified a Material Conflict. In such cases, the proxy shall be submitted to the Proxy Committee, which may authorize a vote against ISS's recommendation or proxy voting guidelines only if the Proxy Committee determines that such vote is in the clients' best interests. No employee, officer or director of Babson or its affiliates (other than those assigned such responsibilities under the Policy) may influence how Babson votes any proxy, unless such person has been requested to provide such assistance by a Portfolio Manager or Proxy Committee member and has disclosed any known Material Conflict. Any pre-vote communications prohibited by the Policy shall be reported to the Proxy Committee member prior to voting and to Babson's General Counsel. Obtaining a Copy of the Policy ------------------------------ The full text of Babson's Policy is available (1) without charge, upon request, by calling 1-866-399-1516 or (2) on the Registrant's website, www.babsoncapital.com/mpv.
