Box 173673 Denver, Colorado 80217-3673 1-800-647-7374 Internet website: www.babsoncapital.com/mpv INVESTMENT OBJECTIVE AND POLICY MassMutual Participation Investors (the "Trust") is a closed-end management 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. 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.

TO OUR SHAREHOLDERS August 9, 2005 We are pleased to present the June 30, 2005 Semi-Annual Report of MassMutual Participation Investors (the "Trust"). At the Trust's Quarterly Board of Trustees Meeting, which was held on July 15, 2005, the Trustees announced that Stuart H. Reese had stepped down as Trustee and Chairman of the Board of Trustees as a result of his new position as President and CEO of Massachusetts Mutual Life Insurance Company ("MassMutual"). Subsequently, Roger W. Crandall, former President of the Trust, was appointed as a Trustee and elected to succeed Mr. Reese as Chairman of the Board of Trustees. Mr. Crandall currently serves as Chairman of Babson Capital Management LLC ("Babson"), the Trust's investment advisor, and Executive Vice President and Chief Investment Officer of MassMutual, Babson's parent company. In addition, the Trustees appointed Michael H. Brown as a Trustee, thereby increasing the size of the Board from seven to eight. Mr. Brown recently retired from Morgan Stanley, where he held the role of Managing Director in the Fixed Income Division. Mr. Brown has 24 years of investment experience. The Board of Trustees elected me, Clifford M. Noreen, to succeed Mr. Crandall as President of the Trust at their July 15, 2005 meeting. I was previously a Vice President of the Trust, and am currently the head of the Corporate Securities Group at Babson, where I oversee all corporate credit related investments, including public and private bonds, mezzanine, and private equity investments, as well as structured credit products. Prior to this role, I was responsible for all public corporate bond investments for Babson. I look forward to serving as President of the Trust. The Trust's Board of Trustees declared a quarterly dividend of 24 cents per share, payable on August 12, 2005 to shareholders of record on July 29, 2005. A dividend of 24 cents per share was paid in the previous quarter. U.S. equity markets, as measured by several broad market indices, posted mixed returns. During the quarter ended June 30, 2005, large stocks, as approximated by the Dow Jones Industrial Average, decreased 1.63%, while smaller stocks, as approximated by the Russell 2000 Index, increased 4.32%. For the six months ended June 30, 2005, returns were -3.65% and -1.25%, respectively. U.S. fixed income markets, as measured by selected indices, increased during the quarter. The Lehman Brothers Government/Credit Index and the Lehman Brothers U.S. Corporate High Yield Index increased 3.44% and 2.76%, respectively, for the quarter. For the six months ended June 30, 2005, returns were 2.75% and 1.11%, respectively. For the quarter ended June 30, 2005, the Trust earned 23 cents per share. The Trust earned 23 cents per share in the previous quarter. The Trust's net assets as of June 30, 2005 totaled $115,868,406 or $11.93 per share compared to $111,110,593 or $11.46 per share on March 31, 2005. This translated into a portfolio return of 6.32% for the quarter, and 9.47% for the six months ended June 30, 2005, based on the change in the Trust's net assets assuming the reinvestment of all dividends. Long term, the Trust's portfolio had average annualized returns of 24.53%, 11.81%, 13.77%, and 12.86% for the 1-, 5-, 10- and 15- year time periods ended June 30, 2005, respectively, based on change in net assets with the reinvestment of all dividends. During the quarter, the Trust made private placement investments in three new issuers and closed one "follow on" investment, totaling approximately $3.6 million. The follow on investment purchased by the Trust was in Tomah Holdings, Inc. The three new issuers the Trust invested in were AmerCable, Inc., Arrow Tru-Line Holdings, Inc., and Consolidated Foundries Holdings. The weighted average coupon of these investments was 12.00%. (A brief description of these investments can be found in the Schedule of Investments.) Thank you for your continued interest in and support of MassMutual Participation Investors.

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 whollyowned 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 of the Trust ("MMPI Subsidiary Trust") for the purpose of holding certain investments. The results of the MMPI Subsidiary Trust are 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 29 MASSMUTUAL PARTICIPATION INVESTORS NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited) 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 private placement restricted securities valued at $78,849,592 (68.05% of net assets) as of June 30, 2005 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 June 30, 2005, subject to discount where appropriate, and are approved by the Trustees. Short-term securities with more than sixty days to maturity are valued at fair value and short-term securities having a maturity of sixty days or less are valued at amortized cost, which approximates market value. B. ACCOUNTING FOR INVESTMENTS: Investment transactions are accounted for on the trade date. Dividend income is recorded on the ex-dividend date. Interest income is recorded on the accrual basis. The Trust 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: No provision for federal income taxes on net investment income and short-term capital gains is considered necessary for the Trust because it is a "regulated investment company" under the Internal Revenue Code, and intends to maintain this qualification by, among other things, distributing 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. 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 six months ended June 30, 2005 the MMPI Subsidiary Trust has accrued tax expense on net realized and unrealized gains of $81,427 and $459,629, 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. 30 MASSMUTUAL PARTICIPATION INVESTORS NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited) 3. INVESTMENT ADVISORY AND ADMINISTRATIVE SERVICES CONTRACT A. SERVICES: Under an Investment Advisory and Administrative Services Contract (the "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 negotiated 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 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. B. FEE: For its services under the 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. A majority 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. C. BASIS FOR BOARD RENEWAL OF THE CONTRACT: At a meeting of the Board of Trustees of the Trust held on April 22, 2005, the Board of Trustees (including a majority of the Trustees who are not "interested persons" of the Trust or Babson Capital) unanimously approved the continuance of the Contract. Prior to the meeting, the Board of Trustees requested and received from Ropes & Gray LLP ("Ropes & Gray"), counsel to the Trust, a memorandum describing the Board of Trustees' legal responsibilities in connection with its review and reapproval of the Contract. The Board of Trustees also requested and received from Babson Capital extensive written and oral information regarding: the principal terms of the Contract; the reasons why Babson Capital was proposing the continuance of the Contract; Babson Capital and its personnel; the Trust's investment performance, including comparative performance information; the nature and quality of the services provided by Babson Capital to the Trust; financial strength of Babson Capital; the fee arrangements; fee and expense information, including comparative fee and expense information; profitability of the advisory arrangement to Babson Capital; and "fallout" benefits to Babson Capital resulting from the Contract. Among other things, the Trustees discussed and considered with management (i) the aforementioned guidance provided by Ropes & Gray and the information provided by Babson Capital prior to the meeting and (ii) the reasons Babson Capital put forth in support of its recommendation that the Trustees approve the continuance of the Contract. These reasons are summarized below. NATURE, EXTENT AND QUALITY OF SERVICES TO BE PROVIDED BY BABSON CAPITAL In evaluating the scope and quality of the services provided by Babson Capital, the Trustees considered, among other factors: (i) the scope of services required to be provided by Babson Capital under the Contract; (ii) Babson Capital's ability to find and negotiate private placement securities having equity features; (iii) the experience and quality of Babson Capital's staff; (iv) the financial strength of Babson Capital's financial condition; (v) the nature of the private placement market compared to public markets (including the fact that finding, analyzing, negotiating and servicing private placement securities is more labor-intensive than buying and selling public securities and the administration of private placement securities is more extensive, expensive, and requires greater time and expertise than a portfolio of only public securities); (vi) the Trust's ability to co-invest in negotiated private placements with MassMutual; and (vii) the expansion of the scope of services provided by Babson Capital as result of regulatory and legislative initiatives that have required increased legal, compliance and business attention and diligence. Based on such considerations, the Board of Trustees concluded that, overall, they are satisfied with the nature, extent and quality of services provided, and expected to be provided in the future, under the renewed Contract. INVESTMENT PERFORMANCE The Board also examined the Trust's short-term, intermediate- term, and long-term performance as compared against 31 MASSMUTUAL PARTICIPATION INVESTORS NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited) appropriate benchmark indices presented at the meeting, which showed that the Trust had outperformed such indices for the 1, 3, 5, and 10-year periods. In addition, the Trustees considered comparisons of the Trust's performance with the performance of (i) selected closed-end investment companies and funds that may invest in private placement securities and/or bank loans; (ii) selected business development companies with comparable types of investments; and (iii) investment companies included in the Lipper closed-end bond universe. It was acknowledged that, while such comparisons are helpful in judging performance, they are not directly comparable in terms of types of investments and due to the fact that the business development companies often reported returns based on market value, which is affected by factors other than the performance of the underlying portfolio investments. Based on these considerations and the detailed performance information provided to the Trustees at the regular Board meetings each quarter, the Trustees concluded that the Trust's absolute and relative performance over time have been sufficient to warrant re-approval of the Contract. ADVISORY FEE/COST OF SERVICES PROVIDED AND PROFITABILITY/ MANAGER'S "FALL-OUT" BENEFITS In connection with the Trustees' consideration of the advisory fee paid by the Trust to Babson Capital under the Contract, Babson Capital noted that it was unaware of any closed-end investment companies that are directly comparable to the Trust in terms of the types of investments and percentages invested in private placement securities (which require more extensive advisory and administrative services than a portfolio of publicly traded securities, as previously discussed) other than MassMutual Corporate Investors ("Corporate Investors"), which also is advised by Babson Capital and pays a quarterly advisory fee equal to 5/16 of 1% of the fund's NAV (an amount equivalent to 1.25% on an annual basis) subject to a quarterly performance adjustment of 1/16 of 1% (approximately equal to .25% on an annual basis). It was also noted that the shareholders of Corporate Investors would be voting on a proposal to eliminate the performance fee component of Babson Capital's advisory fee in August of 2005. In considering the fee rate recommended under the Contract, the Trustees noted the Trust's different investment objectives between the Trust and Corporate Investors and the advisory fee charged by Tower Square Capital Partners, L.P. ("Tower Square"), a more recent private mezzanine fund managed by Babson Capital that commenced operations in 2002. Tower Square has an advisory fee of 1.5% of committed capital during the 5-year investment period and 1.25% of net invested capital thereafter plus an incentive allocation of 20% of net realized gains after investors have received a cumulative 8% internal rate of return. At the request of the Trustees, Babson Capital also provided information concerning the profitability of Babson Capital's advisory relationship with the Trust. The Board also considered the non-economic benefits Babson Capital and its affiliates derived from its relationship with the Trust, including the reputational benefits derived from having the Trust listed on the New York Stock Exchange, and the de minimis amount of commissions resulting from the Trust's portfolio transactions used by Babson Capital for third-party soft dollar arrangements (less than $1,000). The Trustees recognized that Babson Capital should be entitled to earn a reasonable level of profits for services provided to the Trust and, based on their review, concluded that they were satisfied that Babson Capital's level of profitability from its relationship with the Trust was not excessive and that the advisory fee structure under the Contract was reasonable. ECONOMIES OF SCALE The Trustees considered the concept of economies of scale and possible advisory fee reductions if the Trust were to grow in assets. Given that the Trust is not continuously offering shares, such growth seemed unlikely. The Trustees also examined the scale down features of selected competitive funds and noted that the minimum starting point for fee reductions in those funds was at least $200 million whereas the Trust current net assets are near $100 million. The Trustees further noted that the Trust is a relatively small, closed-end registered investment company that has not grown significantly in the past and is not likely to grow significantly in the future. The Trustees concluded that the absence of breakpoints in the fee schedule under the Contract was acceptable given the Trust's size and circumstances. 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 six months ended June 30, 2005, the Trust incurred total interest expense on the Note of $348,000. The Trust may redeem the Note, in whole or in part, at the principal amount proposed to be redeemed together with the 32 MASSMUTUAL PARTICIPATION INVESTORS NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited) 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. As of June 30, 2005, there was $10,500,000 in outstanding loans against the Revolver and the average blended rate of interest attributable to the Revolver was 3.22%. For the six months ended June 30, 2005, the Trust incurred total interest expense on the Revolver of $167,608, plus $8,527 related to the undrawn portion. 5.

AGGREGATE REMUNERATION PAID TO OFFICERS, TRUSTEES AND THEIR AFFILIATED PERSONS For the six months ended June 30, 2005, the Trust has paid its Trustees aggregate remuneration of $54,375. 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 "1940 Act")) of the Trust. Messers. Reese and Joyal were each classified 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. For the six months ended June 30, 2005, Mr. Reese, one of the Trust's Trustees, was an "affiliated person" (as defined by the 1940 Act) of MassMutual and Babson Capital. The Trust did not make any payments to Babson Capital for the six months ended June 30, 2005, other than amounts payable to Babson Capital pursuant to the Investment Advisory and Administrative Services Contract. For the six months ended June 30, 2005, the Trust paid the following amounts to 33 MASSMUTUAL PARTICIPATION INVESTORS NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited) MassMutual, exclusive of interest expense on the Note explained in Footnote 4A: Preparation of the Trust's Quarterly and Annual Reports to Shareholders 11,868 Preparation of Certain of the Trust's Shareholder communications 526 Preparation of the Trust's Annual Proxy Statements 1,084 ------- $13,478 ======= 8. CONTINGENCIES The Trust, together with other investors, including MassMutual, is a plaintiff in litigation connected 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 was settled in the Spring of 2005. Under the terms of the settlement agreement, the Trust recovered all legal fees it incurred to prosecute the lawsuit, as well as additional amounts. A related lawsuit brought by the Trustee of the Sharp bankruptcy estate against Sharp's auditors on behalf of unsecured creditors, including the Trust, was also settled at the same time. Total net proceeds to be distributed to the Trust as a result of the settlement of these two lawsuits against Sharp's auditors are expected to be approximately $750,000, of which $458,619 has already been received by the Trust. 9. RESULTS OF SHAREHOLDER MEETING The Annual Meeting of Shareholders was held on Friday, April 22, 2005. Prior to the Annual Meeting, Steve Kandarian resigned from the Board of Trustees. Mr. Kandarian also withdrew his agreement to stand for re-election. As a result, the size of the Board of Trustees was reduced from 8 to 7 members and only two Trustees stood for re-election at the Annual Meeting. At the Annual Meeting, Shareholders were asked to vote to re-elect, and they did vote to re-elect Jack A. Laughery and Corine T. Norgaard as trustees each for a three-year term.

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 newlyissued 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.)
