 INVESTMENT
OBJECTIVE AND
   POLICY

BACKGROUND

MassMutual Participation Investors, a closed-end investment company, had its
initial public offering in October 1988 and its shares are listed on the New
York Stock Exchange. The share price of Participation Investors can be found in
the financial section of most newspapers as "MasPrt" or "MassMuPrt" under the
New York Stock Exchange listings. The trading symbol is "MPV".

INVESTMENT OBJECTIVE

The investment objective of the Trust is to maximize total return by providing a
high level of current income, the potential for the growth of income, and
capital appreciation, by investing primarily in a portfolio of privately placed
fixed income securities, at least half of which normally include equity
features. The Trust will also invest in publicly-traded securities, again with
emphasis on convertible issues. Equity related issues provide the opportunity to
realize capital gains, which, if realized will be reinvested in income-producing
securities, permitting the Trust to increase its future dividend payments.

DIVIDEND POLICY

The Trust pays quarterly dividends and intends to distribute substantially all
of its net income to shareholders each year. All registered shareholders are
automatically enrolled in the Dividend Reinvestment and Cash Purchase Plan
unless cash distributions are requested.

Dividends are distributed in January, May, August and November.

ANNUAL MEETING

MassMutual Participation Investors' Annual Meeting of Shareholders is scheduled
to be held on April 23, 1999 at 1:00 p.m. in Springfield, Massachusetts.
We cordially invite all shareholders to attend.

PORTFOLIO REVIEW

As of December 31, 1998, the Trust had approximately 76% of its portfolio in
private placement securities. In 1998, the Trust closed a total of 17 new or
add-on private placements for a total of $21.4 million. In the fourth quarter,
the Trust closed 3 private placement securities totalling $6.1 million. The
private placements that were added in the fourth quarter are ATI Acquisition
Corporation, America's Body Co., and Lund International Holdings, Inc. (A brief
description of each of these investments is provided in the Schedule of
Investments.) The fixed income components of these investments have a weighted
average coupon of 11.64% per anum.

Private placement investments are the core of Participation Investors'
portfolio. These investments normally have a fixed income component with an
equity feature (mezzanine investments). Generally, private placement investments
are made by institutions. By investing alongside MassMutual, Participation
Investors is able to offer individual shareholders access to an otherwise
unavailable asset class. This is where we believe we add the most value.

Net investment income for the three months ended December 31, 1998 rose to
$2,369,911 or $.26 per share, from $2,086,536 or $.23 per share for the prior
quarter. The primary reason for the increase is that the third quarter's numbers
reflected certain
<PAGE>
 
one-time charges and the fourth quarter's numbers reflect some one-time fees
received.

The table on the right shows some of the highlights of the gains realized from
the portfolio during the year.

An advantageous event that happened in January 1999 was the sale of Lloyd's
Barbecue Company. A little more than a year ago, we made an investment of
approximately $1.75 million in Lloyd's. In January, the company was sold and we
received a gain on our investment of $2.1 million.

An issue that has received a lot of attention this past year is "Year 2000" or
"Y2K". Y2K is one of MassMutual's highest priorities. As of December 31, 1998,
MassMutual's critical computer technology hardware and software, including
applications supporting the Trust, was substantially "Year 2000 Compliant"
according to MassMutual Y2K certification standards. To address the issue of
interdependency between the company and external entities, MassMutual is seeking
assurances from vendors, customers, service providers, governments and others,
to determine their Year 2000 readiness. MassMutual will consider the responses
to these inquiries in the development of any contingency plans needed for Year
2000.

ANOTHER YEAR OF EXPANSION IN THE U.S.

1998 marked the eighth consecutive year of economic expansion in the United
States, once again confounding those who were looking for the economy to falter.
While economic growth continued, inflation remained virtually dormant. Producer
prices, which often lead changes in consumer prices, actually declined in 1998.
Interest rates fell for most of the year, ending December at near-record low
levels. Contributing to the easing of interest rates was the fact that the U.S.
government had a $70 billion surplus in fiscal year 1998 after several decades
of deficits. Another surplus is forecast for the current fiscal year.

OVERSEAS: SOME PROGRESS, SOME NEW CHALLENGES

In Asia, where severe financial problems first came to a head in 1997, there was
some progress. The stock markets of Thailand and South Korea rebounded
noticeably in 1998, indicating that investors are beginning to overcome their
generalized fear of Southeast Asian markets and instead are making investment
decisions on a nation-specific basis. This is a key prerequisite for meaningful
recovery in the region.

One key concern continues to be the extent to which the problems in Asia will
spread to other emerging markets, and eventually to the U.S. This concern gained
renewed force in August, when Russia announced a substantial devaluation of its
currency, the ruble, and defaulted on much of its foreign debt.

EQUITIES AND BONDS RIDE THE ROLLER COASTER

U.S. equities were uniformly strong during the first three months of the year,
as concerns about Asia receded into the background and investors focused on
strong economic growth. In April, a two-tiered market emerged, with
large-capitalization technology and other growth issues leading the S&P 500
Index and the Dow Jones Industrial Average higher through mid-July. The Russell
2000 Index, however, trended lower throughout the second quarter, indicating
that many small-capitalization stocks were not participating in the rally.
Indeed, even the S&P 500's gains are largely due to its twenty largest
components. The rally, therefore, was quite narrow.

</TABLE> 

Bonds were by no means immune to the third quarter's volatility. Up to that
point, interest rates, which began the year at low levels, had trended
irregularly lower, as the yield curve gradually flattened.

As happened with equities, the credit markets regained some confidence when the
Federal Reserve Board lowered interest rates. Spreads narrowed considerably by
year-end, although not nearly to their levels before the crisis.

LOOKING AHEAD TO 1999

The central economic event of 1999 is likely to be a mild slowdown in the U.S.
economy. Softness in corporate earnings, a symptom of reduced consumer spending,
may be evident. Federal Reserve Board policy, which was extremely accommodating
in response to the 1998 crisis in the financial markets, has returned to a
neutral stance and will likely remain so until circumstances clearly mandate a
change. Inflation may rise a little but should remain unthreatening. In this
environment, we should continue to serve shareholders well with our focus on
thorough research and identifying value in the financial markets.

                     Sincerely,

                     Stuart H. Reese

Michael P. Hermsen, Vice President


Michael P. Hermsen and Michael L. Klofas are officers of the Trust responsible
for the origination, analysis and execution of new investments made by
MassMutual Participation Investors and the ongoing monitoring of existing
portfolio companies.

Prior to every investment we make, we perform an extensive analysis and
evaluation of the underlying company. The companies in which we invest are
usually leaders in their industries and provide products or services which are
highly valued by their customers. Companies that become part of the MassMutual
Participation Investor's portfolio also have demonstrated stable historical cash
flows, with future cash flows being reasonably predictable. Perhaps most
importantly, companies in which we invest have strong management teams and are
usually owned by experienced investor groups, also known as sponsor groups.

A critical factor in the success of the Trust's investment activities is our
development of strong relationships with our portfolio companies and the sponsor
groups which own them. Each year, a significant number of new investment
opportunities are brought to us by sponsor groups with whom we have previously
done business, or from other sponsor groups which have been referred to us.
These groups recognize the value of relationship investing and appreciate our
responsiveness, long-term investment perspective and ability to provide
additional capital to portfolio companies if needed.

Despite the difficulties experienced by many financial markets during 1998,
investment opportunities in the private placement mezzanine market remained
plentiful. Additionally, favorable market conditions enabled us to liquidate a
number of holdings and realize significant gains upon their disposition.

================================================================================
1. 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 closed-end diversified management investment company, whose
   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 
   fixed-income securities, at least half of which normally will include equity
   features.

   On January 27, 1998, the Board of Trustees authorized the formation
   of a totally held subsidiary ("MMPI Subsidiary Trust") for the purpose of
   holding certain investments. The results of MMPI 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 generally accepted accounting principles. 
   
   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 as of 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 thereafter
   used 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 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; 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 Massachusetts Mutual Life Insurance Company ("MassMutual"),
   the Trust's investment adviser. In making valuations, the Trustees will
   consider reports by MassMutual analyzing each portfolio security in
   accordance with the relevant factors referred to above. MassMutual has agreed
   to provide such reports to the Trust at least quarterly.

   The financial statements include restricted securities valued at $90,091,617
   (85.64% of net assets) as of December 31, 1998 ($104,464,368 at December 31,
   1997) 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, 1998, 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 cost basis of debt securities is not adjusted for amortization of
   premium since the Trust does not generally intend to hold such investments
   until maturity; however, the Trust has elected to accrue, for financial
   reporting purposes, certain discounts which are required to be accrued for
   federal income tax purposes. 

   Realized gains and losses on investment transactions and unrealized
   appreciation and depreciation of investments are reported for financial
   statement and federal income tax purposes on the identified cost method. 

   The Trust does not accrue income when payment is delinquent and when
   management believes payment is questionable.

   C. Use of Estimates: 

   The preparation of financial statements in conformity with generally accepted
   accounting principles 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.

3. INVESTMENT ADVISORY AND ADMINISTRATIVE
   SERVICES FEE

   Under an investment advisory and administrative services contract with the
   Trust, MassMutual has agreed to use its best efforts to present to the Trust
   a continuing and suitable investment program consistent with the investment
   objective and policies of the Trust. MassMutual has further agreed that it
   will request each issuer of securities which MassMutual is prepared to
   purchase in a private placement, and which would be consistent with the
   investment policies of the Trust, to offer such securities also to the Trust
   and that it will use its best efforts to insure that such request is acceded
   to. MassMutual has agreed that, subject to such orders of the Securities and
   Exchange Commission as may apply, it will invest concurrently with the Trust
   in any such investment. MassMutual will also represent the Trust in any
   negotiations with issuers, investment banking firms, securities brokers or
   dealers and other institutions or investors relating to the Trust's
   investments. Under the contract, MassMutual is obligated to provide
   administration of the day-to-day operations of the Trust and to provide the
   Trust with office space and office equipment, safekeeping facilities,
   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, MassMutual is paid a quarterly advisory and administrative services
   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, provided that a majority of the Trustees, including
   a majority of the Trustees who are not interested persons of the Trust or of
   MassMutual, approve the valuation of the Trust's net assets as of such day.

4. SENIOR SECURED INDEBTEDNESS

   A. Note Payable

   On July 15, 1995, the Trust sold to MassMutual at par a $12,000,000 Senior
   Fixed Rate Convertible Note due July 15, 2002 (the "Note") which accrues at
   6.93% per annum. The Note holder, at is option, can convert the principal
   amount of the Note into common shares. The dollar amount of principal would
   be converted into an equivalent dollar amount of common shares based upon the
   average price of the common shares for ten business days prior to the notice
   of conversion. For each of the periods ended December 31, 1998 and 1997, the
   Trust incurred total interest expense on the Note of $831,600. 

   B. Revolving Credit Agreement 

   The Trust entered into a $15,000,000 senior secured, floating rate,
   revolving credit agreement (the "Revolver") with Fleet National Bank (the
   "Agent Bank"), pursuant to a credit agreement dated May 29, 1997, with a
   maturity date of May 31, 2004.
   
   The Revolver bears interest at a variable per annum rate equal to the
   three-month Eurodollar rate plus a margin of .40 percent per annum or the
   most recent Federal Funds rate plus a margin of .50 percent per annum.
   Interest is paid to the Agent Bank as it becomes due. The Trust also incurs
   expense on the undrawn portion of the total approved credit agreement at a
   rate of .185 percent per annum. 

   As of December 31, 1998, there were $10,500,000 in outstanding loans
   against the Revolver and the average blended rate of interest charged on
   the Revolver was 5.64%. For the period ended December 31, 1998, the Trust
   incurred total interest expense on the Revolver of $639,832, including
   $8,279 related to the undrawn portion.

INDEPENDENT ....................................................................
ACCOUNTANTS    To the Shareholders and the Board of Trustees of MassMutual   
               Participation Investors

================================================================================

   In our opinion, the accompanying consolidated statement of assets and
   liabilities, including the schedule of investments at December 31, 1998, and
   the related consolidated statements of operations, cash flows and of changes
   in net assets and the selected Per Share Data present fairly, in all material
   respects, the financial position of MassMutual Participation Investors
   (hereafter referred to as the "Trust") at December 31, 1998 and 1997, the
   results of its operations, its cash flows and the changes in its net assets
   for the years then ended and the selected Per Share Data for each of the ten
   years in the period then ended, in conformity with generally accepted
   accounting principles. These financial statements and selected Per Share Data
   (hereafter referred to as "financial statements") are the responsibility of
   the Trust's management; our responsibility is to express an opinion on these
   financial statements based on our audits. We conducted our audits of these
   financial statements in accordance with generally accepted auditing standards
   which 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 test basis, evidence supporting
   the amounts and disclosures in the financial statements, assessing the
   accounting principles used and significant estimates made by management, and
   evaluating the overall financial statement presentation. We believe that our
   audits, which included confirmation of securities at December 31, 1998 by
   correspondence with the custodian, provide a reasonable basis for the opinion
   expressed above.

    DIVIDEND
REINVESTMENT AND
 CASH PURCHASE
     PLAN

MassMutual Participation Investors offers a Dividend Reinvestment and Cash
Purchase Plan. 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).

Any questions regarding the Plan should be addressed to Shareholder Financial
Services, Inc., Agent for MassMutual Participation Investors' Dividend
Reinvestment and Cash Purchase Plan, P.O. Box 173673, Denver CO 80217-3673.
