MML Series Investment Fund (the "MML Trust") is a no-load, open-end, diversified
management investment company having four separate series of shares (the
"Funds"), each of which has different investment objectives and is designed to
meet different investment needs.     

THE FUNDS

MML Equity Fund - The investment objectives are primarily to achieve a superior
total rate of return over an extended period of time from both capital
appreciation and current income and secondarily, depending upon business and
economic conditions, to preserve capital. The Fund invests primarily in 
equity-type securities.

MML Money Market Fund - The investment objectives are to achieve high current
income, the preservation of capital, and liquidity. The Fund invests in 
short-term debt instruments, including commercial paper, certificates of
deposit, bankers' acceptances, and obligations of the United States, its
agencies and instrumentalities. An investment in the Fund is neither insured nor
guaranteed by the U.S. Government, and there can be no assurance that the Fund
will be able to maintain a stable net asset value of $1.00 per share.

MML Managed Bond Fund - The investment objective is to achieve as high a total
rate of return on an annual basis as is considered consistent with the
preservation of capital. The Fund invests primarily in investment grade,
publicly-traded, fixed income securities.

MML Blend Fund - The investment objective is to achieve as high a level of total
rate of return over an extended period of time as is considered consistent with
prudent investment risk and the preservation of capital. The Fund invests in a
portfolio of common stocks and other equity-type securities, bonds and other
debt securities with maturities generally exceeding one year, and money market
instruments and other debt securities with maturities not exceeding one year.
    
For further information about each Fund's investment objectives and policies,
see "THE FUNDS" on page 9. There is no assurance that the investment objectives
of the Funds will be realized.

Funds that a prospective investor ought to know before investing. Certain

II. Management Discussion

A. Economic and Investment Environment
    
The past year saw the continuation of a very good economic environment for
investors in both stocks and bonds.  The U.S. economic growth rate as measured
by Gross Domestic Product continued to slow throughout the year from its heated
level of 4.1% in 1994 to roughly 2.5% in 1995.  The Federal Reserve, which had
been raising rates during 1994 in an attempt to slow growth somewhat, was able
to change course and even move rates lower.  Because the economy is cyclical,
the Fed wanted growth to slow to a more moderate, sustainable level - a "soft
landing" from 1994's rapid pace - to prolong the positive part of the current
cycle.     
    
As demand for goods slowed from 1994 levels, businesses began reducing their
inventories, which had started the year at high levels.  This in turn slowed
order and production-driven demand from the manufacturing sector, which exerted
further downward pressure on the growth rate, supported the cause for interest
rate cuts, and helped keep inflation at bay.     
    
While the Federal Reserve actually increased rates as late as February 1995, the
bond market had begun to rally as early as November 1994 on the belief that
growth would slow enough to indicate a change in monetary policy.  The market
was correct.  The Fed's February rate increase of 1/2 point was followed during
the year by two cuts of 1/4 point each in July and December.  Rates on
Treasuries fell significantly during this period, which drove dramatic price
appreciation for Treasuries.  The prices in most other bond sectors followed
suit, with 1995 playing out to be one of the strongest bull markets for bonds in
history.     
    
Backed by low interest rates and a strong bond market, stocks reached all-time
highs in 1995.  The Dow Jones Industrial Average made new highs almost daily,
hitting a peak of 5216 and closing the year at 5117, and the S&P 500 rose
37.58%.  In addition to support from the bond market, stocks reacted to
continued positive earnings surprises, merger and consolidation activity, an
improving export picture and growing productivity and efficiency throughout
corporate America.     
    
The forecast for the economy and markets appears favorable, though both should
be somewhat more moderate than they were during the past year.  Economic growth
will probably slow further because employment and personal income - which are
important components of demand - are not strong enough to fuel increases in
demand-driven growth.     
    
Even in the face of a slower economy, sales and earnings remained strong through
the end of 1995.  The U.S. had its biggest productivity gain on record in 1995
and exports grew, aided in the early part of the year by a weak dollar, which in
turn created improvements in trade.  Going into 1996, we expect to see exports
remain strong, as U.S. businesses recognize that future growth will come in part
from operating in a global market.  This opinion is supported by the heavy
outlays we've seen for business equipment, which should further enhance
competitiveness, productivity and export activity for the coming year.     
    
Because of uncertainty about the slowing in the economy throughout 1995, growth
investing, or buying stocks of companies whose earnings growth rates can surpass
that of the economy, took the lead last year.  By the same token it was growth,
rather than income, that led to the dramatic appreciation of 1995's bond market.
With both markets currently at high levels in terms of price, we believe we will
see a return of superior performance from value investing strategies.  Value
investing relies on capturing appreciation by "buying well" and seeking out
fundamental values, rather than buying above-average growth.  Value investors
like the MML Series Investment Fund work to buy stocks and bonds that are either
temporarily out-of-favor with the markets, or that offer opportunities that have
not yet been recognized by the investment community at large.     
    
With stocks and bonds at highs and an economy that is likely to continue to
slow, we expect both the stocks and bond markets to return to more "normal"
activity in terms of returns and volatility.  In this type of environment, value
investing should continue to offer solid long-term results.  Since security
selection should be very important in the coming year, your portfolio managers
will continue to rely upon hands-on research and careful analysis in an effort
to find the best opportunities for investors.

B. MML EQUITY

How has the Fund performed over the period?

The Fund has performed very well, with 1995 returns at nearly three times the
long-term average for stocks.  Typically, our value-oriented style has not
outperformed the broad market indices in years where absolute gains have been as
robust as in 1995.  Over the long term, however, our value strategy - focusing
on dividend-paying companies with strong balance sheets while their stocks are
selling at what we consider low prices - has been very successful.

How did large company stocks perform in 1995?

Large company stocks were the place to be this year.  Benefiting from improved
productivity, falling interest rates and, through August, a weak dollar, large
companies were able to turn in earnings at levels more typical of small company
growth stocks, which drove their prices up.  The market's focus on large cap
stocks benefited the Fund.

What strategic moves have you made within the portfolio?

Though we make investments based on researching individual companies rather than
their industry sectors, the biggest move we made over the period was increasing
our exposure to consumer non-durables companies, one of the best performing
sectors for the year.  Our purchases in Albertson's, a major grocery concern and
several consumer goods companies such as American Brands and Kimberly-Clark,
benefited the portfolio considerably. These businesses typically are insulated
from slowing economic growth.  We also increased our holdings in the very strong
financial services area, buying the stock of MBIA, a municipal bond insurer and
Safeco, a large property and casualty insurance firm.  Our higher exposure to
financial services was another plus for the Fund - in fact, looking back, we
would have liked to have owned more.  Over the year, the size of the Fund has
grown, and so has the weighted average market capitalization.  This was a third
benefit during a period of large cap leadership.

What segments of the market are you currently targeting?

Our buying has shifted from consumer non-durables to more cyclical companies.
Because this area suffered price declines over the year as the market favored
sectors with more stable earnings, we've been able to buy stocks at what we
consider compelling values.  We are buying and looking to buy companies that can
benefit from lower basic materials costs and thus improve their profit margins
regardless of the slower economy.

What is your outlook for the Fund?

After the past year, it's become more difficult to find reasonably-priced
stocks, but with inflation and long-term interest rates low, our outlook remains
favorable.  We believe the coming year's market will be positive, but that it
will perform more like its historical average than it did in 1995.  We expect to
see more typical levels of volatility than last year's market.  During the past
year, the broad market advanced significantly.  Going forward, we believe stock
selection will again become more important.  That could benefit the Fund in that
strong stock selection is one of the major advantages of a research-driven value
strategy like ours.

C. MML MONEY MARKET

How has the Fund performed over the period?

The Fund has performed well, remaining on target with its goal of providing
principal preservation and a competitive level of current income by investing in
highly liquid short-term debt instruments.  While longer-term interest rates
continued to decline over the majority of the year, rates for the extremely
short-term securities we focus on remained favorable, and even exceeded rates on
longer-term issues at certain times during the year.     

                                       6
<PAGE>
 
    
What strategic moves have you made within the portfolio?

Over the course of the year, we made one major change.  Both in the early part
of 1995 when it was anticipated and then later when it actually happened, we
lengthened the average maturity of the Fund's portfolio on the likelihood of the
Federal Reserve's interest rate cuts.  By lengthening our maturity, we hoped to
make use of available higher current income levels for as long as possible,
expecting that debt issued after a rate cut would offer lower income levels.
This strategy benefited the Fund by allowing us to maintain our income stream
while the market adjusted to the Fed's actions.

What is your outlook for the Fund?

The Fed eased, or lowered rates, twice in 1995 and may do so again in the first
few months of 1996 depending on the forecast for the economy.  If it appears
that the economy has slowed too far, or if budget discussions are finalized,
another decline is a distinct possibility.  However, we believe that any further
declines will not be significant.  In this environment, we are continuing to
extend maturities in an effort to make the most of the current rates while
maintaining an emphasis on principal stability.  Our outlook for the Fund
remains optimistic, though our performance as always will be tied to any changes
in the Federal Reserve's monetary policy.

D. MML MANAGED BOND

How has the Fund performed over the period?

The Fund's performance has been excellent.  It compares favorably to its market
indices and has been outstanding on an absolute and historical basis.  The past
year has been an extremely strong period for the bond market in general, with
bonds from almost every sector the Fund invests in benefiting from decreasing
interest rates and the price appreciation that accompanies rate declines.

What strategic decisions have you made within the portfolio as a result of lower
rates?

In response to declines in interest rates, our duration increased somewhat over
the period.  A longer duration will help us take advantage of any potential
benefits from further changes in the rate structure. New supply in the market
tended to be longer, particularly in corporate bonds. This was due in part to
lower rates. So increasing our duration has allowed us to continue to track the
duration of the Lehman Government/Corporate Index, which is our benchmark.  The
portfolio's average duration increased over the period from 4.85 years to 5.23
years.

What other strategic moves have you made within the portfolio?

During the year, the Fund grew from $121 million to $159 million in size.  While
this was due in part to asset appreciation and in part to new investments, it
required a great deal of trading activity to become fully invested.  Over the
period we initially increased our holdings of Treasuries, and then we sold some
of our Treasuries as the market improved.  Corporates also performed well over
the period due to strong fundamentals and demand factors.  Additionally, we
increased our holdings of mortgage-backed securities.  Though mortgages are
typically sensitive to prepayment risk, our well-seasoned, well-structured
holdings remained strong throughout the period's declines in rates.

What areas of the market are you currently targeting?

As we believe the corporate market still offers strong potential, though within
a slowing economy, we're employing extensive credit research before investing in
corporate issues.  We also continue to increase our exposure to the mortgage-
backed sector of the market, especially in adjustable rate mortgages, where
we're finding particularly attractive pricing.  Pricing remains an important
part of our investment strategy.  We continue to buy bonds across sectors
wherever we believe we've found appreciation potential through mispriced issues.

What is your outlook for the Fund?

This has been a dramatic year for the bond market and the Fund.  While current
low inflation and slow to moderate economic growth lead us to believe there is
still room for appreciation in the market, it would be very difficult to imagine
repeating 1995's performance.  Our outlook is for the extension of a positive
market environment, where income will again be an important component of total
return.  Within this outlook, we expect the Fund to continue to provide high
total return potential consistent with reasonable risk by maintaining a
diversified portfolio of high quality bonds.

E. MML BLEND

How has the Fund performed over the period?

The Fund has performed quite well, backed by the dramatic appreciation declining
interest rates sparked in both the stock and bond markets. Because of the Fund's
focus on preservation of capital, however, it did not perform as well as some of
its more aggressive peers over this unusual time period. Though it will tend to
lag in strong bull markets, we believe our strategy is prudent for long-term
investors and that it will outperform over time.

Did your allocation between stocks, bonds and cash change over the period?      

                                       7
<PAGE>
 
    
Our stock holdings will normally fall within a range of 50% to 70% of the
portfolio. In the beginning of the year, we were 53% invested in stocks and by
the end of year, they represented approximately 54%. Our core bond holdings at
the end of 1995 represented 15% of the portfolio, down from 19%. In bonds, a
flattening yield curve also indicated a shortening in the average life of our
portfolio. When the yield curve is flatter, investors are typically not well-
compensated for extending into longer-maturity bonds. While this excluded us
from some of the appreciation in the bond market, our bond portfolio performed
well. Our allocation decisions stem from a policy consistent with preservation
of capital. The remainder of the portfolio, approximately 31% up from 28% a year
ago, is invested in short-term securities.      
    
What is your outlook for the Fund?     
    
An environment of low inflation, favorable interest rates and slow to moderate
economic growth suggests the continuation of decent markets for both stocks and
bonds. While results should remain positive, we expect to see a return to more
normal periods for both markets. In stocks, we are positioning the Fund for
greater volatility and selectivity in the coming year and in bonds, we expect
income to again become the most consistent component of total return. We believe
the MML Blend Fund's conservative strategy should position it to perform well
during this more typical market environment.

III. General Information
    
MML Trust is a no-load, open-end, diversified management investment company,
having four separate series of shares. Each Fund has its own investment
objectives and policies. MML Trust was organized as a business trust under the
laws of The Commonwealth of Massachusetts pursuant to an Agreement and
Declaration of Trust dated December 19, 1984, as most recently amended on or
about April 16, 1993. MML Trust was established by Massachusetts Mutual Life
Insurance Company ("MassMutual") for the purpose of providing a vehicle for the
investment of assets of various separate investment accounts established by
MassMutual and its life insurance company subsidiaries, including MML Bay State
Life Insurance Company ("MML Bay State").       

Shares of the Funds are offered solely to separate investment accounts
established by MassMutual and any life insurance company subsidiary.
    
MassMutual is responsible for providing all investment advisory, management, and
administrative services needed by the Funds pursuant to investment management
agreements. MassMutual has entered into investment sub-advisory agreements with
Concert Capital Management, Inc. ("Concert"), a wholly-owned subsidiary of DLB
Acquisition Corp., a controlled subsidiary of MassMutual. These agreements
provide that Concert will manage the equity investments of MML Equity Fund ("MML
Equity") and the Equity Sector (the "Equity Sector") of MML Blend Fund ("MML
Blend"). Both MassMutual and Concert are registered with the Securities and
Exchange Commission (the "SEC") as investment advisers (MassMutual and Concert
referred to hereafter as "Advisers"). For further information, see "Investment
Managers" p.13.      

IV. The Funds

The investment objectives of each Fund discussed below are fundamental policies
and may not be changed without the vote of a majority of that Fund's outstanding
voting shares (as used in this Prospectus, a majority of the outstanding voting
shares of any Fund means the lesser of (1) 67% of that Fund's outstanding shares
present at a meeting of the shareholders if more than 50% of the outstanding
shares are present in person or by proxy, or (2) more than 50% of that Fund's
outstanding shares). There is no assurance that the investment objectives of the
Funds will be realized. The success of these objectives depends to a great
extent upon managements' ability to assess changes in business and economic
conditions. For further information about investment policies and techniques,
see "Investment Practices of the Fund and Related Risks," at page 10.

A. MML EQUITY FUND

The primary investment objective of MML Equity Fund ("MML Equity") is to
achieve a superior total rate of return over an extended period of time from
both capital appreciation and current income.

A secondary investment objective is the preservation of capital when business
and economic conditions indicate that investing for defensive purposes is
appropriate. Occasional investments may be made with the objective of short-term
appreciation when in the judgment of Concert general economic conditions dictate
that they may benefit MML Equity and are consistent with sound investment
procedure.
    
Normally, the assets of MML Equity will be invested primarily in common stocks
and other equity-type securities such as preferred stocks, securities
convertible into common stocks and warrants. Investments are made in securities
of companies which, in the opinion of Concert, are of high quality, offer above-
average dividend growth potential and are attractively valued in the
marketplace. Investment quality and dividend growth potential are evaluated
using fundamental analysis emphasizing each issuer's historical financial
performance, balance sheet strength, management capability and competitive
position. Various valuation parameters are examined to determine the
attractiveness of individual securities. On average, the Fund's portfolio
securities will have price/earnings ratios and price/book value ratios below
those of the Standard & Poor's 500 Composite Stock Price Index (the "S&P 500
Stock Index"). Consideration is also given to securities of companies whose
current prices do not adequately reflect, in the opinion of Concert, the ongoing
business value of the enterprise. These investments may be maintained in both
rising and declining markets. Concert intends to engage in the active management
of MML Equity's portfolio. The portfolio of the Fund is managed by James
MacAllen, Senior Vice President of Concert and David L. Babson and Company
("Babson"). He has been associated with Concert and Babson since January 1,
1996.  Prior to January 1, 1996, Mr. MacAllen was with Hagler, Mastrovita &
Hewitt and prior to that was the President and Chief Investment Officer of
Wilmington Capital Management.      

B. MML MONEY MARKET FUND

The investment objectives of MML Money Market Fund ("MML Money Market") are to
achieve high current income, the preservation of capital, and liquidity. These
objectives are of equal importance.

MML Money Market will invest only in short-term (i.e., 397 days or less
remaining to maturity) debt instruments, including but not limited to commercial
paper; certificates of deposit; bankers' acceptances; short-term corporate
obligations; obligations issued, sponsored, assumed or guaranteed as to
principal and interest by the government of the United States, its agencies or
instrumentalities ("U.S. Government securities"); and certain repurchase
agreements with respect to any of the securities listed above (which underlying
securities must be of the highest quality at the time the repurchase agreement
is entered into but which securities may have maturities of more than one year).
MML Money Market's dollar-weighted average portfolio maturity will be maintained
at 90 days or less.

MML Money Market's non-fundamental investment policy is that, at the time it
acquires a security, it will invest 100% of its net assets in Tier 1 Securities,
but it retains the right to invest no more than 5% of its net assets in Tier 2
Securities. A Tier 1 Security is one that is rated in the highest rating
category by at least one nationally recognized statistical rating organization
("NRSRO") such as Standard & Poor's Corporation ("S&P") or Moody's Investors
Service, Inc. ("Moody's"). MML Money Market will invest no more than 5% of its
total

                                       9
<PAGE>
 
assets in Tier 2 Securities. A Tier 2 Security is one that is rated in the
second highest rating category by at least one NRSRO. Securities which are
unrated may also qualify as Tier 1 and Tier 2 Securities if so determined by the
Board of Trustees of MML Trust (the "Board of Trustees"). For a description of
S&P and Moody's ratings, see the Statement of Additional Information.

Certificates of deposit and bankers' acceptances will be limited to obligations
of banks having deposits of at least $1,000,000,000 as of their most recently
published financial statements. The obligations of U.S. banks in which MML Money
Market may invest include Eurodollar obligations of their foreign branches. In
the case of foreign banks, the $1,000,000,000 deposit requirement will be
computed using exchange rates in effect at the time of their most recently
published financial statements.

Obligations of foreign issuers, including foreign branches of U.S. banks, will
not be acquired if MML Money Market's investment in such obligations would
exceed in the aggregate 25% of its net assets. Foreign obligations may be
affected by foreign governmental action, including imposition of currency
controls, interest limitations, withholding taxes, seizure of assets or the
declaration of a moratorium or restriction on payments of principal or interest.
Foreign branches of U.S. banks and foreign banks may provide less public
information than, and may not be subject to the same accounting, auditing and
financial record-keeping standards, as domestic banks.

MML Money Market will make portfolio investments primarily in anticipation of or
in response to changing economic and money market conditions and trends. Trading
activity is expected to be relatively low. However, it is anticipated that from
time to time, MML Money Market will take advantage of temporary disparities in
the yield relationships among the different segments of the money market or
among particular instruments within the same segment of the market to make
purchases and sales when MassMutual deems that such transactions will improve
the yield or the quality of the portfolio.

The high quality debt instruments in which MML Money Market invests may not
offer as high a yield as may be achieved from lower quality instruments having
less safety. While MML Money Market invests exclusively in First and Second Tier
Securities, investment in MML Money Market is not without risk. If MML Money
Market disposes of an obligation prior to maturity, it may realize a loss or
gain. An increase in interest rates will generally reduce the value of portfolio
investments. In addition, investments are subject to the ability of the issuer
to make payment at maturity. MML Money Market will reassess whether a particular
security presents minimal credit risks in certain circumstances. For example, if
a security ceases to be a Second Tier Security, MML Money Market would dispose
of any such security as soon as practical.

C. MML MANAGED BOND FUND

The investment objective of MML Managed Bond Fund ("MML Managed Bond") is to
achieve as high a total rate of return on an annual basis as is considered
consistent with the preservation of capital.

Normally, the assets of MML Managed Bond will be invested primarily in
investment grade, publicly-traded, fixed income securities of such maturities as
MassMutual deems appropriate from time to time in light of market conditions and
prospects. Except when invested for defensive purposes, at least 80% of total
invested assets at market value at the time of a purchase will consist of U.S.
Government securities and investment grade quality debt securities which have
been rated in the top four rating categories by S&P (AAA, AA, A or BBB) or
Moody's (Aaa, Aa, A or Baa) or, if unrated, which are judged by MassMutual to be
of equivalent quality to securities so rated. While debt securities rated BBB or
Baa are investment grade securities, they have speculative characteristics and
are subject to greater credit risk, and may be subject to greater market risk,
than higher-rated investment grade securities.
    
In implementing the policies set forth in the preceding paragraph, MML Managed
Bond may invest in (1) obligations (payable in U.S. dollars) issued or
guaranteed as to principal and interest by the Government of Canada, a Province
of Canada, or any instrumentality or political subdivision thereof, provided
that no such investment will be made if it would result in more than 25% of MML
Managed Bond's net assets being invested in such securities, and (2) securities
of foreign issuers, provided however, MML Managed Bond may invest not more than
10% of its net assets in such securities, except as provided in (1) above.      

If MML Managed Bond disposes of an obligation prior to maturity, it may realize
a loss or a gain. An increase in interest rates will generally reduce the value
of portfolio investments, and a decline in interest rates will generally
increase the value of portfolio investments. In addition, investments are
subject to the ability of the issuer to make payment at maturity.

Normally, the Fund's duration will range from four to seven years. Portfolio
changes will be accomplished primarily through the reinvestment of cash flows
and selective trading.
    
The portfolio of the Fund is managed by Mary E. Wilson, Senior Managing Director
of MassMutual, with which she has been associated since 1982. As such, she
oversees all public fixed income trading for MassMutual and its related
subsidiaries and affiliates.      

D. MML BLEND FUND

The investment objective of MML Blend Fund ("MML Blend") is to achieve as high
a level of total rate of return over an extended period of time as is considered
consistent with prudent investment risk and the preservation of capital.

The Advisers will adjust the mix of investments among its three market sectors
to capitalize on perceived variations in return potential produced by the
interaction of changing financial market and economic conditions. The Advisers
expects that such adjustments will normally be made in a gradual manner over a
period of time. No investment will be made that would result in more than 90% of
MML Blend's net assets being invested in the Equity Sector or in more than 50%
of MML Blend's net assets being invested in the Bond Sector. Up to 100% of MML
Blend's net assets may be invested in the Money Market Sector. No minimum
percentage has been established for any of the sectors.

In addition to MML Blend's investment objective, each of its market sectors has
a specific investment objective. Within the

                                      10
<PAGE>
 
Equity Sector, MML Blend will attempt to achieve a superior total rate of return
over an extended period of time from both capital appreciation and current
income. Within the Bond Sector, MML Blend will attempt to achieve as high a
total rate of return on an annual basis as is considered consistent with the
preservation of capital. Within the Money Market Sector, MML Blend will attempt
to achieve high current income, the preservation of capital, and liquidity. The
portfolio of the Fund is managed by committee.

In seeking a high rate of return from dividends, interest income and capital
appreciation as well as in seeking to preserve capital, Advisers intend to
engage in the active management of MML Blend's portfolio. (See "Portfolio
Management" on page 12).

The portfolio of MML Blend will be invested in the following three market
sectors:

1. Equity Sector
    
The Equity Sector generally invests in equity-type securities in a substantially
similar manner as described in the discussion of MML Equity Fund on page 9. 
     

2. Bond Sector
    
The Bond Sector generally invests in the types of bonds and other debt
securities described in the discussion of MML Managed Bond on page 10 with
maturities usually exceeding one year. The Bond Sector may also invest in debt
securities not described above, including lower quality securities and non-rated
securities acquired directly from issuers in direct placement transactions,
provided no such transaction shall cause such debt securities to exceed 10% of
MML Blend's total assets. Lower quality debt instruments generally provide
higher yields but are generally subject to greater market fluctuations and risk
of loss of income and principal than higher quality debt securities. During
1995, no debt securities were acquired by MML Blend which were not rated at
least BBB by S&P or Baa by Moody's.      

3. Money Market Sector
    
The Money Market Sector invests in money market instruments and other debt
securities with maturities generally not exceeding one year. For example, it may
invest in:

   (a)  U.S. Treasury Bills and other U.S. Government securities,

   (b)  obligations (payable in U.S. dollars) issued or guaranteed as to
        principal and interest by the Government of Canada, (such obligations
        may not exceed 25% of MML Blend Fund's total assets),

   (c)  commercial paper, including variable amount master notes, having a
        rating at the time of purchase within the two highest grades as
        determined by Moody's (P-1 or P-2) or S&P (A-1 or A-2),

   (d)  publicly-traded bonds, debentures and notes having a rating within the
        four highest grades as determined by Moody's (Aaa, Aa, A or Baa) or S&P
        (AAA, AA, A or BBB), or

   (e)  securities of foreign issuers.      

While debt securities rated BBB or Baa are investment grade securities, they
have speculative characteristics and are subject to greater credit risk, and may
be subject to greater market risk, than higher-rated investment grade
securities.

V. Investment Practices Of The Funds and Related Risks

In managing their portfolios of investments, the Funds, pursuant to policies
adopted by the Board of Trustees or where considered appropriate by Advisers,
may engage in various investment-related practices. The Funds' significant
investment practices, which are pursuant to non-fundamental policies and
therefore may be changed by the Board of Trustees without consent of
shareholders, regarding these investment transactions and practices are
discussed below. For further information see the Statement of Additional
Information.

A. DERIVATIVES TRANSACTIONS
    
Each Fund is authorized to engage in transactions involving derivatives, as more
fully described in the Statement of Additional Information. The Funds' use of
derivatives, other than forward contracts, is minimal. The Funds may use
Derivatives to attempt to: (a) protect against possible declines in the market
value of a Fund's portfolio resulting from downward trends in the debt
securities markets generally due to increasing interest rates, (b) protect a
Fund's unrealized gains or limit unrealized losses in the value of its
securities, (c) to establish a position in the debt securities markets as a
temporary substitute for purchasing or selling particular debt securities, (d)
to manage the effective maturity or duration of fixed-income securities in a
Fund's portfolio, or (e) to manage its exposure to changing security prices
(collectively, "Derivatives Transactions"). Most, if not all, of these
transactions will involve the portfolios of MML Managed Bond and the Bond Sector
of MML Blend as MML Trust has no present intent to enter into derivatives
transactions with regard to MML Money Market, MML Equity, or the Equity or Money
Market Sectors of MML Blend. The Funds will not use Derivatives for speculative
purposes.

Each Fund may purchase or sell securities on a "when issued" or delayed delivery
or on a forward commitment basis ("forward contracts"). When such transactions
are negotiated, the price is fixed at the time of commitment, but delivery and
payment for the securities can take place a month or more after the commitment
date. The securities so purchased or sold are subject to market fluctuations,
and no interest accrues to the purchaser during this period. At the time of
delivery, the securities may be worth more or less than the purchase or sale
price.

There can be no assurance that the use of forward contracts or other derivatives
by any of the Funds will assist it in achieving its investment objectives. Risks
inherent in the use of derivatives include: (1) the risk that interest rates and
securities prices will not move in the direction anticipated; (2) imperfect
correlation between the prices forward contracts and the prices of the
securities being hedged; (3) the fact that skills needed to use these strategies
are different from those needed to select portfolio      

                                      11
<PAGE>
 
    
securities; and (4) forward contracts involve a risk of a loss if the value of
the security to be purchased declines prior to the settlement date, which is in
addition to the risk of decline of the Funds' other assets. 

A Fund will not enter into a forward contract if as a result more than 25% of
the Fund's total assets would be in one or more segregated accounts covering
forward contracts.     

B. PORTFOLIO MANAGEMENT

Advisers intend to use trading as a means of managing the portfolios of the
Funds in seeking to achieve their investment objectives. Advisers, on behalf of
the Funds, will engage in trading when they believe that the trade, net of
transaction costs, will improve interest income or capital appreciation
potential, or will lessen capital loss potential.

Whether the goals discussed above will be achieved through trading depends on
Advisers' ability to evaluate particular securities and anticipate relevant
market factors, including interest rate trends and variations from such trends.
Such trading places a premium on Advisers' ability to obtain relevant
information, evaluate it properly and take advantage of their evaluations by
completing transactions on a favorable basis. If Advisers' evaluations and
expectations prove to be incorrect, a Fund's income or capital appreciation may
be reduced and its capital losses may be increased. Portfolio trading involves
transaction costs, but, as explained above, will be engaged in when Advisers
believe that the result of the trading, net of transaction costs, will benefit
the Funds.

C. RESTRICTED AND ILLIQUID SECURITIES

The Funds may invest in illiquid securities up to 15% (10% in the case of MML
Money Market) of each Fund's net assets. Each Fund currently expects to invest,
if anything, no more than 10% of its net assets in such securities. This policy
does not limit purchases of securities eligible for resale to qualified
institutional buyers pursuant to Rule 144A under the Securities Act of 1933 that
are determined to be liquid by the Board of Trustees or by Advisers pursuant to
Board approved guidelines. Such guidelines take into account trading activity
for such securities and the availability of reliable pricing information, among
other factors. If there is a lack of trading interest in particular Rule 144A
securities, a Fund's holdings of those securities may be illiquid. There may be
undesirable delays in selling these securities at prices representing fair
value.
    
D. SECURITIES LENDING      

MML Managed Bond and MML Blend may make loans of portfolio securities of not
more than 10% of their respective total assets taken at current value, thereby
realizing additional income. Although lending portfolio securities may involve
the risk of delay in recovery of the securities loaned or possible loss of
rights in the collateral should the borrower fail financially, loans will be
made only to borrowers deemed by MassMutual to be of good standing.
    
E. FEDERAL TAXES      

The extent to which the Funds may enter into Derivatives transactions and engage
in portfolio trading may be limited by the Internal Revenue Code's requirements
for qualification for regulated investment companies. It is each Fund's
intention to qualify as such. See "Certain Tax and Accounting Information" in
the Statement of Additional Information.
    
F. CASH POSITIONS      

Each Fund, other than MML Money Market, may hold cash or cash equivalents to
provide for liquidity (e.g. expenses and anticipated redemption payments) and so
that an orderly investment program may be carried out in accordance with the
Fund's investment policies. To provide liquidity or for temporary defensive
purposes, each Fund may invest any portion of its assets in investment grade
debt securities and MML Equity may also invest in non-convertible preferred
stocks.

VI. Investment Restrictions

The following is a description of certain investment restrictions, and
exceptions to such restrictions, that apply to each Fund which may not be
changed without a vote of a majority of the outstanding shares of such Fund.
(For a description of additional investment restrictions, reference should be
made to the Statement of Additional Information.)

Each Fund will not:
    
(1) Pledge or mortgage assets taken at market to an extent greater than 15% of
the total assets of the Fund taken at cost;      
    
(2) Borrow money, except from banks as a temporary measure for extraordinary or
emergency purposes (but not for the purpose of making investments), and except
to the extent that each Fund engages in financial futures transactions (as
described on page 11) and in reverse repurchase agreements (as described on page
12), provided (a) that the aggregate amount of all such borrowings at the time
of borrowing does not exceed 10% of the total assets of the Fund taken at cost,
and (b) that immediately after the borrowing, and at all times thereafter, there
will be an asset coverage of at least 300% for all of the Fund's borrowings
(including all obligations under financial futures contracts on debt
obligations); and      
    
(3) Concentrate its investments in any one industry, as determined by the Board
of Trustees, and in this connection it will not acquire securities of companies
in any one industry if, immediately after giving effect to any such acquisition,
more than 25% of the value of the total assets of the Fund would be invested in
such industry, with the following exceptions:      
    
    (a) In the case of MML Money Market there is no limitation in respect of
    certificates of deposit and bankers' acceptances (see "The Funds - MML Money
    Market Fund" on pages 9-10).     

    (b) MML Money Market, MML Managed Bond and the Bond Sector of MML Blend each
    may invest up to 40% of the value of their respective total assets in each
    of the electric utility and telephone industries. However, it 

                                      12
<PAGE>
 
    currently is MassMutual's intent not to invest more than 25% of any one of
    these funds total assets in either the electric utility or telephone
    industries. 


VII. Investment Managers
    
MassMutual serves as investment manager of each Fund pursuant to a separate
investment management agreement executed by MassMutual and each Fund. Under the
agreements, which are substantially identical, MassMutual is authorized to
engage in portfolio transactions on behalf of the Funds, subject to such general
or specific instructions as may be given by the Board of Trustees. MassMutual
also acts as the transfer agent and the dividend paying agent.

The investment management agreements between MassMutual and the Funds provide
that MassMutual will perform all administrative functions relating to the Funds
and will bear all expenses of the Funds except (1) taxes and corporate fees
payable to government agencies, (2) brokerage commissions (which may be higher
than other brokers charge if paid to a broker which provides brokerage and
research services to Advisers or for use in providing investment advice and
management to the Funds and other accounts over which Advisers exercise
investment discretion) and other capital items payable in connection with the
purchase or sale of Fund investments, (3) interest on account of any borrowings
by the Funds, (4) fees and expenses of Trustees of MML Trust who are not
interested persons, as defined in the Investment Company Act of 1940, as amended
(the "1940 Act"), of the Advisers or MML Trust, and (5) fees of the Funds'
independent certified public accountants.

For providing the services described above, MassMutual is paid a quarterly fee
at the annual rate of .50% of the first $100,000,000 of the average daily net
asset value of each Fund, .45% of the next $200,000,000, .40% of the next
$200,000,000 and .35% of any excess over $500,000,000. MassMutual has agreed to
bear expenses of each Fund (other than the management fee, interest, taxes,
brokerage commissions and extraordinary expenses) in excess of .11% of average
daily net asset value through April 30, 1997. In 1995 MML Equity, MML Money
Market, MML Managed Bond, and MML Blend paid fees to MassMutual amounting to
 .40%, .50%, .49% and .37%, respectively, of their average daily net assets
during the year.      

The investment management agreement between MassMutual and each Fund
automatically terminates: (1) unless its continuance is specifically approved at
least annually by the affirmative vote of a majority of the Board of Trustees,
which affirmative vote shall include a majority of the members of the Board who
are not interested persons (as defined in the 1940 Act) of MassMutual or of MML
Trust, or (2) upon its assignment. Under the terms of each investment management
agreement, each Fund recognizes MassMutual's control of the initials "MML" and
each Fund agrees that its right to use these initials is non-exclusive and can
be terminated by MassMutual at any time. Under each agreement, MassMutual's
liability regarding its investment management obligations and duties is limited
to situations involving its willful misfeasance, bad faith, gross negligence or
reckless disregard of such obligations and duties.

    
MassMutual is a mutual life insurance company organized in 1851 under the laws
of The Commonwealth of Massachusetts. MassMutual is licensed to transact a life,
accident and health insurance business in all states of the United States, the
District of Columbia and certain Provinces of Canada. At December 31, 1995
MassMutual had total assets of approximately $50 billion and in excess of $100
billion in assets under management.

As of January 1, 1993, MassMutual transferred its equity investment advisory
operations to Concert.  All of the senior investment professionals of
MassMutual's Equity Management Department transferred to and became employees of
Concert. MassMutual indirectly owns 100% of DLB Acquisition Company which owns a
controlling interest in both Concert and Babson.  As of January 1, 1996, the
employees of Concert became co-employees of Babson. Concert manages
institutional investment advisory accounts and had, as of December 31, 1995,
$5.7 billion of assets under management.      

    
Pursuant to two investment sub-advisory agreements with MassMutual, Concert
manages the investment of the assets of MML Equity and the Equity Sector of MML
Blend and MassMutual pays Concert a quarterly fee equal to an annual rate of
 .13% of the average daily net asset value. The agreements provide that they
automatically terminate upon the termination of the respective investment
management agreements between MassMutual and MML Equity and MML Blend. Concert
also serves as the investment sub-adviser to Oppenheimer Value Stock Fund which
had net assets of $163 million as of December 31, 1995.      

Securities held by the Funds are also frequently held by Advisers in their
investment accounts and by other investment companies for which Advisers act as
investment advisers. If the same security is purchased or sold for any Fund and
such investment account or companies at the same time, such purchases or sales
normally will be combined, to the extent practicable, and will be allocated as
nearly as practicable on a pro rata basis in proportion to the amounts to be
purchased or sold for each. In determining the amounts to be purchased or sold,
the main factors to be considered will be the investment objectives of the
respective portfolios, the relative size of portfolio holdings of the same or
comparable security, availability of cash for investment by the various
portfolios and the size of their respective investment commitments. It is
believed that the ability of the Funds to participate in larger volume
transactions will, in most cases, produce better execution for the Funds. In
some cases, however, this procedure could have a detrimental effect on the price
and amount of a security available to a Fund or the price at which a security
may be sold. It is the opinion of MML Trust's management that, such execution
advantage and the desirability of retaining Advisers as investment managers of
the Funds outweigh the disadvantages, if any, which might result from this
procedure.

VIII. Capital Shares

MML Trust is a "series" company which is authorized to issue shares in separate
series of the same class. Shares of four series have been authorized,
constituting the interests in the four Funds described in this Prospectus. Under
MML Trust's Declaration of Trust, however, the Board of Trustees is authorized
to create new shares in addition to the Funds without the necessity of a vote of
shareholders of MML Trust. MML 

                                      13
<PAGE>
 
Trust may issue an unlimited number of shares of the same class, in one or more
series as MML Trustees may authorize, with or without par value as MML Trustees
may prescribe. Each share of a particular series represents an equal
proportionate interest in that series with each other share of the same series,
none having priority or preference over another. Each series shall be preferred
over all other series in respect of the assets allocated to that series. Each
share of a particular series is entitled to a pro rata share of any
distributions declared by that series and, in the event of liquidation, a pro
rata share of the net assets of that series remaining after satisfaction of
outstanding liabilities. When issued, shares are fully paid and nonassessable
and have no preemptive, conversion or subscription rights.

MML Trust is not required to hold annual meetings of shareholders. Special
meetings may be called for purposes such as electing MML Trustees, voting on
management agreements, and with respect to such additional matters relating to
MML Trust as may be required by MML Trust's Declaration of Trust and the 1940
Act. Shareholders holding 10% of the shares of MML Trust may call a meeting to
be held to consider removal of MML Trustees. On any matter submitted to
shareholders, shares of each Fund entitle their holder to one vote per share
(with proportionate voting for fractional shares), irrespective of the relative
net asset values of the Funds' shares. On any matters submitted to a vote of
shareholders, all shares of MML Trust then entitled to vote shall be voted by
individual Fund, except that (i) when required by the 1940 Act, shares shall be
voted in the aggregate and not by individual Fund, and (ii) when MML Trustees
have determined that any matter affects only the interests of one or more Funds,
then only shareholders of such Fund or Funds shall be entitled to vote thereon.
Shareholder inquiries should be made by contacting the Secretary, MML Series
Investment Fund, 1295 State Street, Springfield, Massachusetts 01111.

The assets of certain variable annuity and variable life insurance separate
accounts for which MassMutual or an affiliate is the depositor are invested in
shares of the Funds. Because these separate accounts are invested in the same
underlying Funds it is possible that material conflicts could arise between
owners of the variable life insurance contracts and owners of the variable
annuity contracts. Possible conflicts could arise if (i) state insurance
regulators should disapprove or require changes in investment policies,
investment advisers or principal underwriters or if the depositor should be
permitted to act contrary to actions approved by holders of the variable life or
variable annuity contracts under rules of the Securities and Exchange
Commission, (ii) adverse tax treatment of the variable life or variable annuity
contracts would result from utilizing the same underlying Funds, (iii) different
investment strategies would be more suitable for the variable annuity contracts
than the variable life contracts, or (iv) state insurance laws or regulations or
other applicable laws would prohibit the funding of both variable life and
variable annuity separate accounts by the same Funds.

The Board of Trustees will follow monitoring procedures which have been
developed to determine whether material conflicts have arisen and what action,
if any, should be taken in the event of such conflicts. If a material
irreconcilable conflict should arise between owners of the variable life
insurance contracts and owners of the variable annuity contracts, one or the
other group of owners may have to terminate its participation in the Funds. More
information regarding possible conflicts between variable annuity and variable
life insurance contracts is contained in the prospectuses for those contracts.

Under Massachusetts law, shareholders could, under certain circumstances, be
held personally liable for the obligations of MML Trust. However, MML Trust's
Declaration of Trust disclaims liability of the shareholders, MML Trustees, or
officers of MML Trust for acts or obligations of MML Trust, which are binding
only on the assets and property of MML Trust, and requires that notice of such
disclaimer be given in each agreement, obligation, or instrument entered into or
executed by MML Trust or MML Trustees. MML Trust's Declaration of Trust provides
for indemnification out of MML Trust property for all loss and expense of any
shareholder held personally liable for the obligations of MML Trust. Thus, the
risk of a shareholder incurring financial loss on account of shareholder
liability is considered remote since it is limited to circumstances in which the
disclaimer is inoperative and MML Trust itself would be unable to meet its
obligations.

IX. Net Asset Value

The net asset value of each Fund's shares is determined once daily as of the
normal close of trading on the New York Stock Exchange (presently 4:00 p.m.) on
each day on which the Exchange is open for trading.

A. MML MONEY MARKET FUND

It is the intention of MML Money Market to maintain a per share net asset value
of $1.00, although this cannot be assured. Since the net income of MML Money
Market is declared as a dividend each time it is determined, the net asset value
per share of MML Money Market remains at $1.00 per share immediately after each
determination and dividend declaration. Any increase in the value of a
shareholder's investment in MML Money Market representing the reinvestment of
dividend income is reflected by an increase in the number of shares of MML Money
Market in the shareholder's account, which increase is recorded promptly after
the end of each calendar month. MML Money Market's portfolio instruments are
valued on the basis of amortized cost.

B. OTHER FUNDS

Generally, the other Funds value portfolio securities on the basis of market
value. For example, equity securities, including those traded on national
securities exchanges, the NASDAQ national market system, or over-the-counter
securities not so listed, are valued by one or more pricing services, as
authorized by the Board of Trustees. Normally, the values are based upon the
last reported sale price of the security. Long-term bonds are valued on the
basis of valuations furnished by a pricing service, authorized by the Board of
Trustees, which determines valuations taking into account appropriate factors
such as institutional-size trading in similar groups of securities, yield,
quality, coupon rate, maturity, type of issue, trading characteristics and other
market data. Debt obligations with less than one year but more than sixty days
to maturity are valued on the basis of their market value, and debt obligations
having a maturity of sixty days or less are generally valued at amortized cost
when the Board of Trustees believes that amortized cost approximates market
value. If acquired, preferred stocks will be valued on the basis of their market
value if market quota-

                                      14
<PAGE>
 
tions are readily available. Futures contracts are valued based on market prices
unless such prices do not reflect the fair value of the contract, in which case
they will be valued by or under the direction of the Board of Trustees. In all
other cases, assets (including restricted securities) will be valued at fair
value as determined in good faith by the Board of Trustees, although the actual
calculations may be made by persons acting pursuant to the direction of the
Board of Trustees.

X. Sale And Redemption
Of Shares

The shares of each Fund are sold at their net asset value (which in the case of
MML Money Market is expected to remain at $1.00) as next computed after receipt
of the purchase order, without the deduction of any selling commission or "sales
load."

Each Fund redeems its shares at their net asset value (which in the case of MML
Money Market is expected to remain at $1.00) as next computed after receipt of
the request for redemption. The redemption price for shares of MML Equity, MML
Managed Bond and MML Blend may be more or less than the shareholder's cost. No
fee is charged on redemption.

Redemption payments will be made within seven days after receipt of the written
request therefore by MML Trust, except that the right of redemption may be
suspended or payments postponed when permitted by applicable law and
regulations.

XI. Tax Status
    
It is the policy of each Fund to comply, and in 1995 each Fund did comply, with
the provisions of the Internal Revenue Code applicable to regulated investment
companies. As a result, none of the Funds will be subject to federal income tax
on any net income or any capital gains to the extent they are distributed or are
deemed to have been distributed to shareholders.      

Regulations issued under Internal Revenue Code Section 817(h) require each of
the Funds to be adequately diversified in order for a variable annuity and
variable life contract funded by MML Trust to receive favorable tax treatment as
an annuity or life insurance contract. Among other requirements, the regulations
limit each Fund's investment in a single issuer to 55% of its assets; while this
requirement applies to U.S. Government securities, each government agency or
instrumentality is treated for this purpose as a separate issuer. The Funds
intend to comply with these diversification requirements. For further
information, see the Statement of Additional Information.

Tax consequences to investors in the separate investment accounts which are
invested in the Funds are described in the prospectuses for such accounts.

XII. Dividends And Capital Gains Distributions

The Funds intend to declare capital gain and ordinary income dividends and to
distribute such dividends in a manner designed to avoid a 4% excise tax on
undistributed regulated investment company income, imposed by the Tax Reform Act
of 1986. The declaration and distribution policies specific to each Fund are
outlined below.

A. MML EQUITY FUND

Distributions, if any, are declared and paid annually. Distributions may be
taken either in cash or in additional shares of MML Equity at net asset value on
the day after the record date for the distribution, at the option of the
shareholder.

B. MML MONEY MARKET FUND

The net income of MML Money Market, as defined below, is determined as of the
normal close of trading on the New York Stock Exchange on each day on which the
Exchange is open, and all the net income so determined is declared as a dividend
to shareholders of record as of that time. Dividends are distributed promptly
after the end of each calendar month in additional shares of MML Money Market at
the then current net asset value, or in cash, at the option of the shareholder.

For this purpose the net income of MML Money Market (from the time of the
immediately preceding determination thereof) consists of all interest income
accrued on its portfolio, plus realized gains or minus realized losses, and less
all expenses and liabilities chargeable against income. Interest income includes
discount earned (including both original issue and market discount) on paper
purchased at a discount, less amortization of premium, accrued ratably to the
date of maturity. Expenses, including the compensation payable to MassMutual,
are accrued each day.

Should MML Money Market incur or anticipate any unusual expense, or loss or
depreciation which would adversely affect its net asset value per share or
income for a particular period, the Board of Trustees would at that time
consider whether to adhere to the present dividend policy described above or to
revise it in the light of the then prevailing circumstances. For example, if MML
Money Market's net asset value per share were reduced, or were anticipated to be
reduced, below $1.00, the Board of Trustees might suspend further dividend
payments until the net asset value returned to $1.00. Thus, such expenses or
losses or depreciation might result in an investor receiving no dividends for
the period during which he held his shares and in his receiving upon redemption
a price per share lower than that which he paid.

C. MML MANAGED BOND AND MML BLEND FUNDS

Dividends out of net investment income are declared and paid quarterly. Capital
gains declarations and distributions of net capital gains, if any, for the year
are made annually. Distributions may be taken either in cash or in additional
shares of the applicable Fund at net asset value on the day after the record
date for the distribution, at the option of the shareholder.

XIII. Investment Performance

Each of the Funds may from time to time advertise certain investment performance
figures. These figures are based on historical earnings and are not intended to
indicate future performance.

                                      15
<PAGE>
 
MML Money Market may quote its yield and its effective yield. The yield of MML
Money Market refers to the income generated by the Fund over a seven-day period
(which period will be stated in the advertisement). This income is then assumed
to be earned each week over a 52-week period. The effective yield is calculated
similarly, but the income earned by an investment in the Fund is assumed to be
reinvested.

MML Managed Bond, MML Blend and MML Equity may also quote yield. The yield for
each of these Funds refers to the net investment income earned by the Fund over
a 30-day period (which period will be stated in the advertisement). This income
is then assumed to be earned for a full year and to be reinvested each month for
six months. The resulting semi-annual yield is doubled.

Each of the Funds may advertise its total return and its holding period return
for various periods of time. Total return is calculated by determining, over a
period of time, which will be stated in the advertisement, the average annual
compounded rate of return that an investment in the Fund earned over that
period, assuming reinvestment of all distributions. Holding period return refers
to the percentage change in the value of an investment in a Fund over a period
of time (which period will be stated in the advertisement), assuming
reinvestment of all distributions. Total return and holding period return differ
from yield in that the return figures include capital changes in an investment
while yield measures the rate of net income generated by a Fund. Total return
differs from holding period return principally in that total return is an
average annual figure while holding period return is an aggregate figure for the
entire period.

These investment performance figures may be of limited use for comparative
purposes because they do not reflect charges imposed by the separate investment
accounts invested in the Funds which, if included, would decrease the
performance figures. For more information about the investment performance of
the Funds, see the Statement of Additional Information.

XIV. Management Of
MML Trust

The affairs of MML Trust are generally supervised by its Board of Trustees and
officers. As stated previously, MassMutual acts as investment manager of each of
the Funds and Concert is the sub-adviser to MML Equity and the Equity Sector of
MML Blend. In those capacities, MassMutual and Concert are part of the
management of MML Trust. For more information concerning the management of MML
Trust, reference should be made to the Statement of Additional Information.

The name MML Series Investment Fund is the designation of Trustees under a
Declaration of Trust dated December 19, 1984, as amended from time to time. The
obligations of MML Trust are not personally binding upon, nor shall resort be
had to the property of, any of the Trustees, shareholders, officers, employees
or agents of MML Trust, but MML Trust's property only shall be bound.

                            I. GENERAL INFORMATION

MML Series Investment Fund (the "MML Trust") is a no-load, open-end, diversified
management investment company having four separate series of shares (the
"Funds") and established by Massachusetts Mutual Life Insurance Company
("MassMutual") for the purpose of providing a vehicle for the investment of
assets of various separate investment accounts established by MassMutual and
life insurance company subsidiaries of MassMutual.  Shares of MML Trust are not
offered to the general public but solely to separate investment accounts
established by MassMutual and its life insurance company subsidiaries, including
MML Bay State Life Insurance Company ("MML Bay State").  MML Trust was formed as
a voluntary association of the type known as a "business trust" organized under
the laws of the Commonwealth of Massachusetts pursuant to an Agreement and
Declaration of Trust dated December 19, 1984, as amended on or about April 16,
1993 (the "Declaration of Trust").

MassMutual is responsible for providing all investment advisory, management, and
administrative services needed by the Funds pursuant to investment management
agreements.  MassMutual has entered into investment sub-advisory agreements with
Concert Capital Management, Inc. ("Concert").  Concert and David L. Babson, Inc.
("Babson") are both owned by DLB Acquisition Corporation, a controlled
subsidiary of MassMutual.  Concert employees and officers are also employees of
Babson.  These agreements provide that Concert will manage the investment of the
assets of MML Equity Fund ("MML Equity") and the assets of the Equity Sector
("Equity Sector") of the MML Blend Fund ("MML Blend").  MassMutual, Concert and
Babson are registered with the Securities and Exchange Commission as investment
advisers (MassMutual and Concert are referred to hereinafter collectively as
"Advisers").

            II. INVESTMENT PRACTICE OF THE FUNDS AND RELATED RISKS

The following information supplements the discussion of the Funds' investment
objectives, techniques and policies described in  the Prospectus.  The
fundamental investment objectives and investment restrictions of each Fund (as
described in the Prospectus and below) may not be changed without a vote of a
majority of such Fund's outstanding shares.  A "majority of the outstanding
shares" of any Fund means the lesser of (1) 67% of such Fund's outstanding
shares present at a meeting of the shareholders if more than 50% of the
outstanding shares are present in person or by proxy or (2) more than 50% of
such Fund's outstanding shares.  All other investment policies and techniques of
each Fund may be changed by the Board of Trustees of MML Trust without a vote of
shareholders.  For example, such other policies and techniques include
investment in new types of debt instruments which may be devised in the future,
or which are presently in disuse but may become more prominent in the future,
and minor changes in investment policies which may be made in response to
changes in regulatory requirements which are reflected in the present policies
of such Fund.  There is no assurance that the investment objectives of the Funds
will be realized.  The success of these objectives depends to a great extent
upon the Advisers' ability to assess changes in business and economic
conditions.

                                       1
<PAGE>
 
In managing their portfolios of investments, the Funds may purchase various
securities, investment related instruments and make use of various investment
techniques, including those described below.

A. MML Managed Bond ("MML Bond")

It is a non-fundamental policy of MML Bond to invest all of its assets in
investment grade securities as discussed in the Prospectus.  While MML Bond has
no current expectation to invest in non-investment grade securities, it is
authorized to invest up to twenty percent (20%) of its assets in non-investment
grade debt instruments and preferred stocks.  Lower quality debt instruments
involve greater volatility of price and yield, and greater risk of loss of
principal and interest, and generally reflect a greater possibility of an
adverse change in financial condition which would affect the ability of the
issuer to make payments of principal and interest.  The market price for lower
quality securities generally responds to short-term corporate and market
developments to a greater extent than higher-rated securities because such
developments are perceived to have a more direct relationship to the ability of
an issuer of lower quality securities to meet its ongoing debt obligations.

B. MML Blend -- Money Market Sector

The Money Market Sector of MML Blend may invest in commercial paper or notes
issued by companies with an unsecured debt issue outstanding having a rating at
the time of purchase within the three highest grades as determined by Moody's
(Aaa, Aa or A) or S&P (AAA, AA or A) and U.S. dollar denominated foreign
commercial paper.  This sector may also invest in repurchase agreements and
securities of foreign issuers, provided that such securities of foreign issuers
not be more than 10% of the Sector's total assets.

C. Derivatives

Although each Fund is authorized to engage in derivatives transactions as
indicated in the Prospectus, the Funds have no current expectation of entering
into such transactions in a material way other than the use of forward
contracts.  Nonetheless, the following is a discussion of the Funds' authority
to enter into derivative transactions and a description of such transactions and
instruments. Examples of Derivative Transactions include entering into financial
futures transactions, writing covered call options on securities and futures or
covered puts on securities and futures and entering into forward contracts, swap
agreements, and other similar instruments (collectively referred to as
"Derivatives").

The Funds may use Derivatives to try to: (a) protect against possible declines
in the market value of a Fund's portfolio resulting from downward trends in the
debt securities markets generally due to increasing interest rates, (b) protect
a Fund's unrealized gains or limit unrealized losses in the value of its
securities, (c) facilitate selling debt securities for investment reasons, (d)
establish a position in the debt securities markets as a temporary substitute
for purchasing particular debt securities, (e) manage its exposure to changing
security prices, or (f) to manage the effective maturity or duration of fixed
income securities in a Fund's portfolio (collectively "Derivatives
Transactions").

     1. Forward Contracts--Each Fund may purchase or sell securities on a "when
     issued," delayed delivery or on a forward commitment basis ("forward
     contracts").  When such transactions are negotiated, the price is fixed at
     the time of commitment, but delivery and payment for the securities can
     take place a month or more after the commitment date.  The securities so
     purchased or sold are subject to market fluctuations, and no interest
     accrues to the purchaser during this period.  At the time of delivery, the
     securities may be worth more or less

                                       2
<PAGE>
 
     than the purchase or sale price.  The Funds use forward contracts to manage
     interest rate exposure, as a temporary substitute for purchasing or selling
     particular debt securities, or to take delivery of the underlying security
     rather than closing out the forward contract.

     2. Currency Swaps--The Funds may invest in debt securities of foreign
     issuers that are not denominated in U.S. dollars.  In such cases, the Funds
     will enter into currency transaction either to hedge the foreign currency
     risks or to effectively convert the debt security to U.S. dollars.

     3. Interest Rate Swap Agreements--Swap Agreements--An interest rate swap
     agreement involves the exchange by the Fund with another party of their
     respective commitments to pay or receive interest, such as an exchange of
     floating rate payments for fixed rate payments with respect to a notional
     amount of principal.  Interest rate and yield curve swaps may be used by
     MassMutual on behalf of a Fund as a hedging technique to preserve a return
     or spread on a particular investment or portion of its portfolio or to
     protect against any increase in the price of securities a Fund anticipates
     purchasing in the future.  The Funds intend to use these transactions as
     hedges and not as speculative investments.  A Fund usually will enter into
     such agreements on a net basis whereby the two payments of interest are
     netted with only one party paying the net amount, if any, to the other.

     4. Futures--The Funds may enter into exchange-traded futures contracts for
     the purchase or sale of debt obligations in order to hedge against
     anticipated changes in interest rates.  The purpose of hedging in debt
     obligations is to establish the effective rate of return on portfolio
     securities with more certainty than would otherwise be possible.  A futures
     contract on debt obligations is a binding contractual commitment which, if
     held to maturity, will result in an obligation to make or accept delivery,
     during a particular month, of obligations having a standardized face value
     and rate of return.  By entering into a futures contract for the purchase
     of a debt obligation, a Fund will legally obligate itself to accept
     delivery of the underlying security and pay the agreed price; by entering
     into a futures contract for the sale of a debt obligation it will legally
     obligate itself to make delivery of the security against payment of the
     agreed price.  Positions taken in the futures markets are not normally held
     to maturity, but are instead liquidated through offsetting transactions
     which may result in a profit or a loss.

     Unlike the purchase or sale of a security, no price is paid or received by
     a Fund upon the purchase or sale of a futures contract.  The Fund will
     incur brokerage fees in connection with its futures transactions, however,
     and will be required to deposit and maintain funds with its custodian in
     the brokers name as margin to guarantee performance of its future
     obligations.  A Fund initially will be required to deposit with its
     custodian an amount of "initial margin" consisting of cash or U.S. Treasury
     bills currently equal to approximately 1 1/2% of the contract amount.  The
     nature of initial margin in futures transactions is different from that of
     margin in security transactions in that futures contract initial margin
     does not involve the borrowing of funds by a Fund to finance the
     transactions.  Rather, the initial margin is in the nature of a performance
     bond or good faith deposit on the contract which is returned to the Fund
     upon termination of the futures contract, assuming all contractual
     obligations have been satisfied.  Subsequent payments to and from the
     broker will be made on a daily basis as the price of the underlying debt
     security fluctuates, making the long and short positions in the futures
     contract more or less valuable, a process known as "mark to the market".

                                       3
<PAGE>
 
     While futures contracts based on debt securities provide for the delivery
     and acceptance of securities, such deliveries and acceptances usually are
     not made.  Generally, the futures contract is terminated by entering into
     an offsetting transaction. The closing out of a futures contract sale is
     effected by a Fund's entering into a futures contract purchase for the same
     aggregate amount of the specific type of financial instrument and the same
     delivery date.  If the price in the sale exceeds the price in the
     offsetting purchase, the Fund immediately is paid the difference and thus
     realizes gain.  If the offsetting purchase price exceeds the sale price, a
     Fund pays the difference and realizes the loss.  Similarly, the closing out
     of a futures contract purchase is effected by a Fund's entering into a
     futures contract sale for the same aggregate amount of the specific type of
     financial instrument and the same delivery date.  If the offsetting sale
     price exceeds the purchase price, the Fund realizes a gain, and if the
     purchase price exceeds the offsetting sale price, the Fund realizes a loss.
     Instead of entering into an offsetting position, a Fund might make or take
     delivery of the underlying securities whenever it appears economically
     advantageous for it to do so.

     To compensate for the imperfect correlation of movements in the price of
     debt securities being hedged and movements in the price of futures
     contracts, a Fund may buy or sell futures contracts in a greater dollar
     amount than the dollar amount of the securities being hedged if the
     historical volatility of the prices of such securities has been greater
     than the historical volatility of the futures contracts.  Conversely, a
     Fund may buy or sell fewer futures contracts if the historical volatility
     of the price of the securities being hedged is less than the historical
     volatility of the futures contracts.

     5. Call and Put Options

     Call Options--give the right to a person to buy a security at a stated
     price, or strike price, within a stated period.  A call option can be
     exercised during the exercise period if the spot price rises above the
     strike price; if not, the option expires.  A call option backed by the
     securities underlying the option is a covered call option.  The owner of
     the security will normally sell covered call options to collect premium
     income or to reduce price fluctuations of the security.  A covered call
     option limits the capital appreciation of the underlying security.  As a
     writer of a call option, a Fund receives a premium, that may be an
     additional source of income for the Fund, for undertaking the obligation to
     sell the underlying security at a fixed price during the option period if
     the option is exercised. So long as the Fund remains obligated as a writer
     of a call, it forgoes the opportunity to profit from increases in the
     market price of the underlying security above the exercise price of the
     option, except insofar as the premium represents such profit.

     Each Fund may write covered call options which are traded on a national
     securities exchange with respect to securities in its portfolio, provided
     that at all times it will have in its portfolio the securities which it may
     be obligated to deliver if the option is exercised.  Each Fund may write
     call options on securities in its portfolio in an attempt to realize a
     greater current return than would be realized on the securities alone or to
     provide greater flexibility in disposing of such securities. The Fund may
     also enter into "closing purchase transactions" in order to terminate its
     obligation as a writer of a call option prior to the expiration of the
     option. The writing of call options could result in increases in the Funds'
     portfolio turnover rate, especially during periods when market prices of
     the underlying securities appreciate.

                                       4
<PAGE>
 
     Put Options--give the holder the right to sell the underlying securities to
     the Fund during the term of the option at a fixed exercise price up to a
     stated expiration date or, in the case of certain options, on such date.
     Put options are "covered" by a Fund, for example, when it has established a
     segregated account with its Custodian consisting of cash, U.S. Government
     issued securities and other liquid high quality debt securities.  Each Fund
     may also write straddles (combinations of calls and puts on the same
     underlying security).  The writing of straddles generates additional
     premium income but may present greater risk.

     6. Other Derivatives--The Funds may use other derivatives that are or
     become appropriate in the context of each Fund's investment objectives and
     in a manner and to an extent permitted by law and authorized by the Board
     of Trustees pursuant to guidelines proposed by MassMutual.

     7. Derivatives Limitations--The policies limiting the use of Derivatives
     are non-fundamental policies established by the Board of Trustees.  The
     policies may be changed by the Board without obtaining shareholder
     approval.  MML Trust's current non-fundamental policies are:  (1)  A Fund
     would not enter into a futures contract if, immediately after entering into
     the futures contract, more than 5% of the Fund's total assets would be
     committed to initial margin deposits on such contracts; (2)  A Fund will
     not purchase a put or call option on securities or investment related
     instruments if, as a result, more than 5% of its total assets would be
     attributable to premiums paid for such options; (3)  A Fund would not write
     a covered call or put option if as a result more than 20% of the Fund's
     total assets would be in one or more segregated accounts covering call and
     put options; and (4)  A Fund would not enter into a forward contract if as
     a result more than 25% of the Fund's total assets would be in one or more
     segregated accounts covering forward contracts. Additionally, a Fund is
     required at all times to maintain its assets at a level at least three
     times the amount of all of its borrowings (the "300% asset coverage test").
     Borrowings for this purpose include obligations under any futures contract
     on a debt obligation.

     8. Segregated Accounts--If a Fund enters into forward contracts, it must
     cover such contracts by, for example, establishing a segregated account
     with its Custodian, Citibank, N.A., consisting of cash, U.S. Government
     issued securities and other liquid high quality debt securities.  The
     assets of the account must have a value equal to or greater than the
     aggregate amount of that Fund's commitment under forward contracts (that
     is, greater than the aggregate of the purchase price of the underlying
     security on the delivery date). If the value of the securities in the
     segregated account declines, additional cash or high grade liquid assets
     will be placed in the account so that the value of the account will equal
     the amount of the Fund's commitments.  At the time of entering into a
     forward contract, the segregated account covering such forwards shall not
     exceed 25% of the Fund's assets.  As an alternative  to maintaining all or
     part of the segregated account, a Fund could buy call or put options to
     "cover" the forward contracts.  Forward contracts involve a risk of a loss
     if the value of the security to be purchased declines prior to the
     settlement date, which risk is in addition to the risk of decline of the
     Funds' other assets.  A Fund may realize short-term gains or losses upon
     the sale of forward contracts.


     In instances determined by the Board of Trustees, a Fund selling caps and
     floors would maintain in a segregated account cash or high-grade debt
     obligations having an aggregate net asset value at least equal to the full
     amount, accrued on a daily basis, of the Fund's obligations

                                       5
<PAGE>
 
     with respect to any caps or floors.  The purchase of an interest rate cap
     entitles the purchaser, to the extent a specific index exceeds a
     predetermined interest rate, to receive payments on a contractually-based
     notional amount from the party selling the interest rate cap.  The purchase
     of an interest rate floor entitles the purchaser, to the extent that a
     specific index falls below a predetermined interest rate, to receive
     payments of interest on a contractually-based notional principal amount
     from the party selling the interest rate floor.  In instances determined by
     the Board of Trustees, a Fund selling caps and floors would maintain in a
     segregated account cash or high-grade liquid assets having an aggregate net
     asset value at least equal to the full amount, accrued on a daily basis, of
     the Fund's obligations with respect to any caps or floors.

     9. Risks in Using Derivatives--There can be no assurance that the use of
     Derivatives by any of the Funds will assist it in achieving its investment
     objectives.  Risks inherent in the use of futures, options, forward
     contracts, and swaps include:

     a. the risk that interest rates and securities prices will not move in the
     direction anticipated;

     b. imperfect correlation between the price of futures, options, forward
     contracts and the prices of the securities being hedged;

     c. the fact that skills needed to use these strategies are different from
     those needed to select portfolio securities;

     d. the possible absence of a liquid secondary market for any particular
     instrument at any time;

     e. futures contracts and options can be highly volatile;

     f. the writing of call options could result in increases in the Funds'
     portfolio turnover rate, especially during periods when market prices of
     the underlying securities appreciate;

     g. the possible need to defer closing out certain hedged positions to avoid
     adverse tax consequences;

     h. the risk that a Fund will not be able to effect closing purchase
     transactions as to call options it has written at any particular time or at
     any acceptable price; and

     i. forward contracts involve a risk of a loss if the value of the security
     to be purchased declines prior to the settlement date, which is in addition
     to the risk of decline of the Funds' other assets.

D. Other Investments Practices

     1. Repurchase Agreements--MML Money Market, MML Managed Bond, and MML Blend
     may enter into repurchase agreements.  While it is the current expectation
     that not more than 5% of each such Fund's total assets would be invested in
     repurchase agreements at any one time, each such Fund may invest not more
     than 10% of their respective total assets in such agreements.  Under a
     repurchase agreement, a Fund acquires an obligation for a relatively short
     period (usually not more than one week) subject to the agreement of the
     seller (a member bank of the Federal Reserve System or a securities dealer)
     to repurchase the obligation at an agreed upon price and date.  The
     repurchase price reflects an agreed-upon

                                       6
<PAGE>
 
     interest rate unrelated to the coupon rate on the purchased obligation.  A
     repurchase agreement is considered to be loans by a Fund for purposes of
     its investment restrictions.  Investments in repurchase agreements will be
     limited to transactions with financial institutions which are believed by
     MassMutual to present minimal credit risks.  While the repurchase
     agreements will provide that the underlying security at all times shall
     have a value at least equal to the resale price stated in the agreement, if
     the seller defaults, the Fund could realize a loss on the sale of the
     underlying security.  In addition, if the seller should be involved in
     bankruptcy or insolvency proceedings, the Fund may incur delay and costs in
     selling the underlying security or may suffer a loss of principal and
     interest if the Fund is treated as an unsecured creditor and required to
     return the underlying securities to the seller's estate.

     2. Reverse Repurchase Agreement--MML Blend may engage in reverse repurchase
     agreements, which are agreements in which MML Blend, as the seller of the
     securities, agrees to repurchase them at an agreed upon time and price.
     MML Blend will maintain a segregated account which will contain cash or
     high-grade debt obligations having a current market value at all times in
     an amount sufficient to repurchase securities pursuant to outstanding
     reverse repurchase agreements.  Reverse repurchase agreements are
     borrowings subject to the 300% asset coverage test described on page 14 of
     the Prospectus.

     3. Restricted and Illiquid Securities--Rule 144A provides a non-exclusive
     safe harbor exemption from the registration requirements of the Securities
     Act of 1933 for the resale of restricted securities to qualified
     institutional buyers ("QIBs").  If one or more of the Funds invests in Rule
     144A securities or other types of illiquid securities, investors should
     recognize that the investment could have the effect of increasing the level
     of fund illiquidity to the extent that QIBs become uninterested in
     purchasing the securities.  Although  MML Equity, MML Managed Bond, and MML
     Blend may invest up to 15% of their net assets in such securities, they
     each have non-fundamental policies to invest not more than 10% of their
     respective net assets in such securities.  Although MML Money Market may
     invest no more than 10% of its assets in such securities, its current
     policy is that it will invest no more than 5% of its net assets in such
     securities.  These limitations do not apply if MassMutual, Concert, or the
     Board of Trustees determines that they are liquid as discussed in the next
     paragraph.  The policy regarding the extent to which a Fund may invest in
     such securities or instruments is a non-fundamental policy of MML Trust
     which can be changed without obtaining shareholder approval. Although the
     Board of Trustees is responsible for determining the liquidity of
     restricted securities, it is not required to specifically approve and
     review each restricted security recommended by Advisers for the Funds'
     portfolios.  With respect to Rule 144A securities, for example, the Board
     of Trustees is responsible for establishing guidelines for determining the
     liquidity and value of securities and monitoring Adviser's implementation
     of the guidelines.  Such guidelines have been adopted and take into account
     trading activity and the availability of reliable pricing information and
     any other factor of importance.  If there is a lack of trading interest in
     particular Rule 144A securities, the Fund's holdings of those securities
     may become less liquid and there may be undesirable delays in selling these
     securities at prices representing their fair value.  Securities not
     registered for sale to the general public but that can be resold to
     institutional investors may not be considered illiquid, provided that a
     dealer or institutional trading market exists. The institutional trading
     market is relatively new and liquidity of the Funds' investments could be
     impaired if trading does not develop or declines.

     Restricted securities frequently can be purchased at a discount from the
     price of unrestricted

                                       7
<PAGE>
 
     securities of the same class, and the valuation of such securities in the
     Funds' portfolios (which will be their fair value as determined in good
     faith by the Board of Trustees of MML Trust or pursuant to the direction of
     the Board of Trustees subject to its review) will generally reflect such
     discount in whole or in part until the restriction is eliminated.  With the
     exceptions of Rule 144A securities and commercial paper, the Funds
     generally do not expect to purchase restricted securities unless the issuer
     has agreed to pay the expenses of registering such securities under the
     Securities Act of 1933.  However, under some circumstances the Funds may
     dispose of such securities privately at a discount or pay the cost of
     registration.  A considerable period may elapse between the time a Fund
     decides to sell restricted securities and the time a suitable purchaser is
     found or registration is effected.  Any such lapse of time would reduce the
     Fund's flexibility and also delay its ability to dispose of such
     securities, thereby subjecting the Fund to the risk of a market decline in
     the interim or, in a thin market, a decline caused by the proposed sale
     itself.  In disposing of restricted securities, the Funds may be
     underwriters as that term is defined in the Securities Act of 1933.

     4. Warrants--MML Equity may invest in warrants.  A warrant typically gives
     the holder the right to purchase an underlying stock at a specified price
     for a designated period of time.  Warrants may be a relatively volatile
     investment for the holder.  The holder of a warrant takes the risk that the
     market price of the underlying stock may never equal or exceed the exercise
     price of the warrant.  A warrant will expire without value if it is not
     exercised or sold during its exercise period.

     5. Foreign Securities--Generally, the Funds may invest not more than 10% of
     their net assets in the securities of foreign issuers, whether or not the
     securities are listed on a domestic or foreign exchange.  It is the current
     expectation, however, that MML Equity will make no such investments.  If
     such investments are made by MML Managed Bond or MML Blend, it is presently
     expected that no more than 5% of the Fund's net assets will be invested in
     such securities.  Investments in Canadian securities have their own
     limitations as set forth in the Prospectus.

     In making foreign investments, each Fund will be subject to a number of
     factors and risks not generally associated with investments in domestic
     securities.  For example, foreign securities usually are denominated in
     foreign currencies which means that their value will be affected favorably
     or unfavorably by changes in the strength of the U.S. dollar relative to
     other currencies as well as to other factors that affect security prices.
     Moreover, foreign issuers are not subject to uniform legal, accounting,
     auditing, and financial standards and requirements comparable to those
     applicable to U.S. issuers.  Other risks include:  unfavorable political or
     economic developments, applicability of less stringent regulation of
     foreign securities markets, the availability of less information about the
     issuer of the security in question, possible seizure, expropriation or
     nationalization of foreign assets, the imposition of foreign withholding
     tax on dividend or interest payments, greater expenses because of the
     increased transaction costs on non-U.S. securities markets and the
     increased costs of maintaining the custody of foreign securities.  Foreign
     securities markets also have different clearance and settlement procedures.

     6. U.S. Government Obligations--Obligations issued by the U.S. Government
     which MML Money Market, MML Managed Bond and MML Blend may purchase include
     U.S. Treasury bills, notes and bonds having no more than one year remaining
     to maturity.  At present, obligations of United States agencies or
     instrumentalities which MassMutual intends to

                                       8
<PAGE>
 
     purchase for the portfolio of MML Money Market include principally
     obligations of Government National Mortgage Association (which are backed
     by the full faith and credit of the United States) and obligations of the
     Federal National Mortgage Association and the Federal Home Loan Banks
     (which may be backed only by the credit of the issuer itself).

     7. Money Market Instruments: Large Denominations--Certain money market
     instruments are available only in relatively large denominations, and
     others may carry higher yields if purchased in relatively large
     denominations.  For example, yields on certificates of deposit for
     $1,000,000 or over could be higher than yields on certificates of deposit
     for less than $1,000,000.  Also, it is believed by MassMutual that an
     institutional purchaser of money market instruments who has the ability to
     invest relatively large sums on a regular basis may have investment
     opportunities that are not available to those who invest smaller sums less
     frequently.  Certain of the investment restrictions of the Funds, and in
     particular MML Money Market, limit the percentage of its assets which may
     be invested in certain industries or in securities of any issuer.
     Accordingly, while MML Money Market has relatively small net assets and net
     cash flow from sales and redemptions of shares, it may be unable to invest
     in money market instruments paying the highest yield available at a
     particular time.

     8. MML Money Market Investments--All of MML Money Market's assets will
     qualify as Eligible Securities, which include both "First Tier" and "Second
     Tier" Securities, at the time of their purchase.  Eligible Securities may
     also include certain long term securities with, at the time of purchase, a
     remaining maturity of 397 days or less, provided the issuer has received
     from a nationally recognized statistical rating organization, such as
     Standard and Poor's Corporation ("S&P") or Moody's Investors Service, Inc.
     ("Moody's"), a rating with respect to short term obligations in one of the
     top two rating categories, or provided the issuer is similarly rated with
     respect to a class of short-term securities that is comparable in priority
     and security.  A security qualifies as a First Tier Security if two
     nationally recognized statistical rating organizations ("NRSROs") have both
     given it their highest ratings, even if other NRSROs have rated it lower,
     or if one NRSRO has given it the highest rating, but only if the security
     has been rated by only the one NRSRO.  In addition to S & P and Moody's,
     other NRSROs include:  Duff & Phelps, Inc, Fitch Investors, Inc., IBCA
     Limited and IBCA, Inc.  A Second Tier Security is one that is rated in the
     second highest rating category by one or more NRSROs.  In certain
     circumstances, unrated securities may qualify as First or Second Tier
     Securities if MML Trust's Board of Trustees determines that such securities
     are of comparable quality to First or Second Tier Securities and the
     purchase of such unrated securities is approved or ratified by the Board of
     Trustees.  Purchases of securities that have only been rated by one NRSRO
     also must be approved or ratified by MML Trust's Board of Trustees.

     MML Money Market generally is prohibited from investing more than 5% of its
     assets in the securities of one issuer.  The 5% limit also applies to
     investments in bank instruments that are securities, such as certificates
     of deposits, bankers acceptances and letters of credit.  After giving
     effect to the securities collateralizing a repurchase agreement, a fund may
     not invest more than 5% of its assets in any one issuer, including the
     issuer of securities collateralizing the repurchase agreement.  Where the
     underlying securities are not U.S. Government securities, they must be
     First Tier securities at the time the agreement is entered into.  If the
     repurchase agreement is fully collateralized, the fund need look solely to
     the underlying securities to determine whether it meets the diversification
     test.  A safe harbor to the 5% diversification limitation permits a fund to
     invest more than 5% of its assets in First Tier Securities of a single
     issuer for up to 3 business days after the purchase to allow a fund more
     flexibility, such

                                       9
<PAGE>
 
     as, to invest large cash inflows.  This "safe harbor" can only be used by a
     fund for one investment at a time and is only available with respect to 25%
     of the fund's net assets.

     If MassMutual becomes aware that any unrated security or Second Tier
     Security has received a rating by any NRSRO below its second highest rating
     category, MassMutual will either (1) dispose of the security within 5
     business days and so notify the Board of Trustees, or (2) immediately call
     a meeting of the Board to reassess whether such security presents a minimal
     credit risk.  If a First Tier Security ceases to be a First Tier Security,
     MassMutual will reassess promptly whether such security continues to
     present minimal credit risk.  No reassessment is necessary if MassMutual
     promptly determines that it would be in the best interest of the Fund to
     sell such security and promptly does so.  MML Money Market must dispose of
     defaulted securities and securities that are no longer Eligible Securities
     unless the Board determines it would not be in the best interest of the
     fund.  The Board may take into account market conditions that "could affect
     the orderly disposition of the security" (i.e. a fund would not necessarily
     have to dispose of the security in a "fire sale").  If MML Money Market
     holds one or more defaulted securities that, immediately before the
     default, accounted for one half of one percent or more of fund assets, it
     must promptly notify the SEC of this fact and indicate what action it
     intends to take.

     9. Lower Quality Debt Instruments and Preferred Stock--MML Managed Bond and
     MML Blend may invest in debt instruments and preferred stock not rated in
     the top four rating categories by S&P or Moody's.  MML Managed Bond may
     invest not more than 20% of its total invested assets in such investments
     and MML Blend may invest not more than 10% of its total assets in such
     investments.  Lower quality debt instruments involve greater volatility of
     price and yield, and greater risk of loss of principal and interest, and
     generally reflect a greater possibility of an adverse change in financial
     condition which would affect the ability of the issuer to make payments of
     principal and interest.  The market price for lower quality securities
     generally responds to short-term corporate and market developments to a
     greater extent than higher-rated securities because such developments are
     perceived to have a more direct relationship to the ability of an issuer of
     lower quality securities to meet its ongoing debt obligations.  Because of
     the relatively high risks associated with investments in lower quality
     securities, an investor should carefully consider the manner in which MML
     Managed Bond and MML Blend seeks to achieve their investment objectives and
     such investor's ability to assume these risks before investing in MML
     Managed Bond or MML Blend.

     10. Investment Basket--The Board of Trustees, notwithstanding any of the
     investment restrictions set forth in this Statement of Additional
     Information or those set forth in the Prospectus, except those imposed as a
     matter of law, may authorize one or more Funds to invest in any security or
     investment related instrument, or to engage in investment related
     transactions or practices, such as newly developed debt instruments or
     hedging programs, provided that the Board has determined that to do so is
     consistent with the Fund's investment objectives and policies, has adopted
     reasonable guidelines for use by the Fund's Advisers, and provided further
     that at the time of making such an investment or entering into such
     transaction, such investments or instruments account for no more than 10%
     of the Fund's total assets.  MML Trust has no current plans to use this
     authority.

     11. Variable Rate Master Demand Notes--While the Money Market Sector of MML
     Blend may purchase variable rate master demand notes, it has never done so
     and has no current intention of doing so in the foreseeable future.

                                       10
<PAGE>
 
     12. Trading Activity--It is the policy of MML Equity not to invest for the
     purpose of exercising management or control.  It is also the policy of MML
     Equity not to engage in arbitrage activities. In seeking a high rate of
     return from interest income and capital appreciation as well as in seeking
     to preserve capital values, MassMutual intends to engage in the active
     management of MML Managed Bond's portfolio.  MML Money Market will make
     portfolio investments primarily in anticipation of or in response to
     changing economic and money market conditions and trends.  Trading activity
     is expected to be relatively low.  However, it is anticipated that from
     time to time MML Money Market will take advantage of temporary disparities
     in the yield relationships among the different segments of the money
     markets or among particular instruments within the same segment of the
     market to make purchases and sales when management deems that such
     transactions will improve the yield or the quality of the portfolio.

     Advisers intend to use trading as a means of managing the portfolio of MML
     Blend in seeking to achieve its investment objective.  Portfolio trading
     involves transaction costs, but will be engaged in when Advisers believe
     that the result of the trading, net of transaction costs, will benefit the
     Fund.

                          IV. INVESTMENT RESTRICTIONS

A. The following is a description of certain restrictions on investments of the
Funds (in addition to those described in the Prospectus) which may not be
changed without a vote of a majority of the outstanding shares of the applicable
Fund.

Each Fund will not:

     1. Make an investment in the securities of any issuer if such investment
     when made would cause more than 5% of the value of the total assets of the
     Fund to be invested in such securities (other than U.S. Government
     securities), or, in the case of MML Equity Fund, would cause more than 10%
     of the outstanding securities of any class of such issuer to be held by MML
     Equity;

     2. Purchase securities on margin, except for such short-term credits as are
     necessary for the clearance of transactions, and except that each Fund may
     deposit and maintain funds with its custodian or brokers as margin in
     connection with its use of financial futures contracts (see the
     Prospectus);

     3. Purchase commodities or commodity contracts, except to the extent that
     each Fund may enter into financial futures contracts (see the Prospectus);



     4. Purchase the securities of companies which (including predecessors) are
     less than three years old, if such purchase would cause more than 5% of the
     value of the total assets of the Fund to be invested in such companies;

     5. Hold more than 10% of the voting securities of any one company;

     6. Purchase or hold the securities of any company, if to the knowledge of
     the Board of

                                       11
<PAGE>
 
     Trustees of MML Trust, persons who are officers or directors of MassMutual
     or officers or Trustees of MML Trust, and who individually own more than
     1/2 of 1% of the securities of that company, together own more than 5% of
     such securities;

     7. Make short sales of securities;

     8. Write, purchase or sell puts, calls or combinations thereof, except:
     each Fund may write call options on the securities in its portfolio and
     enter into closing purchase transactions with respect thereto (see the
     Prospectus);

     9. Make loans to any officer, Trustee or employee of the Trust or to any
     officer, director or employee of MassMutual, or to MassMutual;

     10. Purchase or sell real estate or interests in real estate, although it
     may purchase and sell marketable securities secured by, or of companies
     investing or dealing in, real estate;

     11. Invest in securities of other investment companies, except (A) as part
     of a merger, consolidation or other corporate acquisition, or (B) by
     purchases in the open market at no more than customary brokers'
     commissions, as a result of which not more than 5% of the value of the
     total assets of the Fund would be so invested and no more than 3% of the
     total outstanding voting stock of any one investment company would be held;

     12. Participate in the underwriting of securities, except to the extent
     that each Fund may be deemed an underwriter under federal securities laws
     by reason of acquisitions or distributions of portfolio securities (e.g.
     investments in restricted securities and instruments subject to such limits
     as imposed by the Board and/or law);

     13. Make loans, except (i) through the acquisition of bonds, debentures,
     notes or other evidences of indebtedness in which the Fund is authorized to
     invest, (ii) in the case of MML Money Market, MML Managed Bond and MML
     Blend, through repurchase agreements (repurchase agreements of each such
     Fund maturing in more than seven days not to exceed 10% of the value of the
     total assets of such Fund), and (iii) in the case of MML Managed Bond and
     MML Blend, through the lending of portfolio securities with respect to not
     more than 10% of the total assets of each such Fund taken at current value.
     (The present intention is that securities loans would be made to broker-
     dealers only pursuant to agreements requiring that the loans be
     continuously secured by collateral in cash or U.S. Government securities at
     least equal at all times to the market value of the securities lent.  The
     borrower pays the Fund an amount equal to any interest or dividends on the
     securities lent.  The Fund also receives the interest on the securities
     purchased with the cash collateral (high-grade interest-bearing short-term
     obligations), or a fee from the borrower.  Although voting rights, or
     rights to consent, with respect to the securities lent pass to the
     borrower, the Fund retains the right to call the loans at any time on
     reasonable notice, and it will do so in order to vote the securities on a
     material event affecting the investment.  Such loans may also be called in
     order to sell the securities involved;

     14. Issue senior securities, except to evidence borrowings permitted by
     investment restriction (2) described in the Prospectus, or

     15. Pledge or mortgage assets at market to an extent greater than 15% of
     the total assets of the

                                       12
<PAGE>
 
     Fund taken at cost.

MML Trust's Agreement and Declaration of Trust provides that MML Trust will
indemnify its Trustees and officers against liabilities and expenses incurred in
connection with litigation in which they may be involved because of their
offices with MML Trust, except if it is determined in the manner specified in
the Agreement and Declaration of Trust that they have not acted in good faith in
the reasonable belief that their actions were in the best interests of MML Trust
or that such indemnification would relieve any Trustee or officer of any
liability to MML Trust or its shareholders by reason of willful misfeasance, bad
faith, gross negligence or reckless disregard of his or her duties.

                 VI. INVESTMENT MANAGEMENT AND OTHER SERVICES

MassMutual serves as investment manager of each Fund pursuant to a separate
investment management agreement between MassMutual and MML Trust on behalf of
each Fund.  Under the agreements, which are substantially identical, MassMutual
is authorized to engage in portfolio transactions on behalf of the Funds,
subject to such general or specific instructions as may be given by the Board of
trustees of MML Trust.

The net asset values of the Funds at December 31, 1995 and the investment
management fees each paid during the past three years were:

Investment Management Fees:

    1995                 $6,344,373           

The Investment Management Agreement with each Fund may be terminated by the
Board of Trustees of MML Trust, or by vote of a majority of the outstanding
shares of such Fund, or by MassMutual.  Such termination requires 60 days'
written notice to be given and may be effected without the payment of any
penalty.  In addition, each such agreement automatically terminates:  (1)
unless its continuance is specifically approved at least annually by the
affirmative vote of a majority of the Board of Trustees of MML Trust, which
affirmative vote shall include a majority of the members of the Board who are
not interested persons (as defined in the Investment Company Act of 1940 as
amended) of MassMutual or of MML Trust, or (2) upon its assignment.  Each
agreement also provides that its continuance will be submitted to the
shareholders of the Fund in the event the use of the initial "MML" is withdrawn
from the Fund by MassMutual.

Advisers entered into two investment sub-advisory agreements effective January
1, 1993 (the "Concert Sub-Advisory Agreements") whereby Concert agreed to assume
MassMutual's duties to manage the investment of the assets of MML Equity and the
Equity Sector of the MML Blend.  MassMutual is ultimately responsible for
providing investment advice to these Funds and will continue to provide
administrative and non-investment advisory services to the Funds. MML Trust will
continue to pay MassMutual its investment management fee at the same rate as in
1993.

MassMutual pays Concert a quarterly fee equal to an annual rate of .13% of the
average daily net asset value of MML Equity as of the close of each business
day for the investment advisory services Concert provides with respect to MML
Equity. MassMutual pays Concert a quarterly fee equal to an annual rate of .13%
of the average daily net asset value of the Equity Sector of MML Blend as of
the close of each business day for the investment advisory services Concert
provides with respect to the Equity Sector of MML Blend. Additionally, Concert
agreed to assume the expenses associated with fund accounting for MML Equity and
the Equity Sector of MML Blend, however, Concert has no responsibility for
providing such fund accounting services.

                                       20
<PAGE>
 
The Sub-Advisory Agreements will terminate automatically upon their assignment
or upon the termination of the respective Management Agreement or by MassMutual
upon sixty days written notice or by liquidation of either MML Equity or the
Equity Sector of MML Blend.  Citibank, N.A., 111 Wall Street, New York, New York
10005, acts as custodian of the cash and securities of each Fund.  As such, it
holds in custody each Fund's portfolio securities and receives and delivers them
upon purchases and sales.

                           VII. BROKERAGE ALLOCATION

Each Fund's Investment Management Agreement with MassMutual provides that the
Fund may pay brokerage commissions which are higher than other brokers would
charge if paid to a broker which provides brokerage and research services to
MassMutual and that MassMutual will follow such practices in placing portfolio
transactions for the Fund as may from time to time be set forth in its
prospectus or specified by the Board of Trustees of MML Trust.  Consistent with
this agreement, the present policy of the Funds and Advisers is that Advisers,
in placing brokerage transactions for the Funds, is to seek best execution by
responsible brokerage firms at reasonably competitive commission rates.  By
virtue of the Sub-Advisory Agreements, Concert is subject to the same rights,
obligations and procedures that apply to MassMutual pursuant to its Investment
Management Agreements with MML Equity and MML Blend.  Advisers evaluate the
overall reasonableness of brokerage commissions they negotiate with their
brokers through their familiarity with commissions charged on comparable
transactions, as well as by comparing commissions paid by the Funds to reported
commissions paid by others.  Advisers review commission rates, research,
execution and settlement services performed, making internal and external
comparisons.

It is MassMutual's current policy not to enter into soft dollar arrangements
with brokers as to fixed-income purchases or sales.  However, MassMutual
reserves it ability to enter into such arrangements if it were to determine that
to do so would be appropriate.  In such a case, MassMutual would seek best
execution by responsible brokerage firms at competitive commission rates.  To
the extent consistent with this policy, brokerage transactions could be placed
with firms which provide brokerage and research services to MassMutual and such
transactions could be paid for at higher rates than other firms would charge.
In placing principal transactions, MassMutual seeks best price and execution and
generally utilizes principal market makers, but when this primary consideration
has been met, such transactions could be placed with brokers who have provided
brokerage and research services.  MassMutual believes that placing brokerage
business with brokers who provide brokerage and research services can be
appropriate in certain circumstances in light of the value of brokerage and
research services in providing investment management to its advisory clients.

With respect to investments by MML Equity and by MML Blend in its Equity Sector,
it is the policy of such Funds and Advisers generally to utilize principal
market makers in placing principal transactions.  With respect to investments by
MML Managed Bond and by MML Blend in its Bond Sector, it is anticipated that
most purchases and sales by such Funds will be with underwriters or with major
dealers in debt instruments acting as principals.  With respect to investment by
MML Money Market and by MML Blend in its Money Market

                                       21
<PAGE>
 
Sector, it is anticipated that most purchases and sales by such Funds will be
with the issuers or with major dealers in money market instruments acting as
principals.  MML Managed Bond, MML Money Market and MML Blend in its Bond and
Money Market Sectors usually do not pay brokerage commissions, although they
will incur other transaction costs.  In connection with all transactions, it is
the Funds' and Advisers' policy to seek best price and execution, but when this
primary consideration has been met, such transactions may be placed with dealers
on the basis of their providing brokerage and research services.  The cost of
securities purchased from underwriters includes an underwriting commission or
concession and the prices at which securities are purchased from and sold to
dealers include a dealer's mark-up or mark-down.  During 1995, no recapture for
the benefit of MML Trust of any brokerage commissions or similar fees paid by
MML Trust on portfolio transactions has been effected.

With respect to MML Equity and the Equity Sector of MML Blend, Concert seeks
best execution by responsible brokerage firms at competitive commission rates.
To the extent consistent with this policy, brokerage transactions may be placed
with firms which provide brokerage and research services to Concert and may be
paid for at higher rates than other firms would charge.  In placing principal
transactions, Concert seeks best price and execution and generally utilizes
principal market makers, but when this primary consideration has been met, such
transactions may be placed with brokers who have provided brokerage and research
services.  Concert believes that placing brokerage business with brokers who
provide brokerage and research services is appropriate in light of the value of
brokerage and research services in providing investment management to its
advisory clients.  Brokerage and research services received include:  advice as
to the value of portfolio securities; the advisability of investing in,
purchasing or selling securities; furnishing analyses and reports concerning
issues, industries, securities, economic factors and trends, portfolio strategy
and performance of accounts; and effecting securities transactions and
performing functions incidental thereto (such as clearance and settlement).
These brokerage and research services will be utilized generally in providing
investment advice and management to accounts over which Advisers exercise
investment discretion, and not all of such services necessarily will be utilized
in providing investment advice and management to the Funds.  Advisers believe
that brokerage and research services are very important in providing investment
advice and management to the Funds, but that they cannot be given a dollar
value.  The receipt of brokerage and research services may reduce the expenses
of Advisers.

At the beginning of each year, Concert estimates the total amount of commissions
expected to be generated by all of its advisory clients, based on commission
rates, past portfolio turnover rates, assets under management, and cash flow
allocated for common stocks.  Concert has agreed on a specific level of
commissions with certain brokers.  Concert allocates approximately 12% of the
total estimated commissions for execution purposes only.  This amount is used
when the best execution is available only through a firm not providing research
services to Concert.  Approximately 70% of the total estimated commissions is
then allocated among those firms providing services of a research or brokerage
nature, with those firms providing relatively more valuable services being
allocated larger shares than those providing less valuable services.  These
allocations then serve as Concert's full-year targets as

                                       22
<PAGE>
 
long as each particular trade falls within Concert's standards for the best
execution including price and commission rate.  At midyear, Concert determines
whether the yearly allocations are still appropriate, and adjustments are made
based on any shifts in relative importance of the services provided, or any
change in the total amount of commissions expected to be generated.  Also,
brokers providing research on specific securities may be compensated during the
year for their research input.  Payments to these so-called "idea firms" may
total 10% to 12% of total commissions for the year.

Employees of MassMutual are primarily responsible for the portfolio decisions of
MML Money Market, MML Managed Bond, and the Money Market Sector and the Bond
Sector of MML Blend.  Employees of Concert are primarily responsible for the
portfolio decisions of MML Equity and the Equity Sector of MML Blend. Such
employees are also responsible for placing their portfolio transactions and,
where applicable, negotiating the rate of brokerage commission paid.

In 1995, $438,167,969 of MML Trust's securities transactions involving $581,849
in brokerage commissions were placed with brokers who furnished research
services.

Richard G. Dooley, Chairman of MML Trust's Board of Trustees, is a director of
Jefferies Group Inc., the parent of Jefferies & Co., a registered broker-dealer.
MML Trust paid aggregate brokerage commissions of $5,104 in 1993, $2,845 in 1994
and $0.00 in 1995.  During 1995, MML Trust did not pay any of its aggregate
brokerage commissions to Jefferies & Co.

                              VIII. CAPITAL SHARES

Under Massachusetts law, shareholders could, under certain circumstances, be
held personally liable for obligations of MML Trust.  However, MML Trust's
Agreement and Declaration of Trust disclaims liability of the shareholders,
Trustees, or officers of MML Trust for acts or obligations of MML Trust, which
are binding only on the assets and property of MML Trust, and requires that
notice of such disclaimer be given in each agreement, obligation, or instrument
entered into or executed by MML Trust or MML Trustees.  The Agreement and
Declaration of Trust provides for indemnification out of MML Trust property for
all loss and expense of any shareholder held personally liable for the
obligations of MML Trust.  Thus, the risk of a shareholder incurring financial
loss on account of shareholder liability is limited to circumstances in which
MML Trust itself would be unable to meet its obligations.  Management believes
that in view of the above the risk of personal liability to shareholders is
remote.




        IX. PURCHASE, REDEMPTION AND PRICING OF SECURITIES BEING OFFERED

                                       23
<PAGE>
 
MML Trust is a no-load mutual fund.  Fund shares are sold at their net asset
value as next computed after receipt of the purchase order, without the addition
of any selling commission or "sales load."  Each Fund redeems its shares at
their net asset value as next computed after receipt of the request for
redemption.  The redemption price may be paid in cash or wholly or partly in
kind if MML Trustees determine that such payment is advisable in the interest of
the remaining shareholders.  In making such payment wholly or partly in kind,
the Fund will, as far as may be practicable, deliver securities or property
which approximate the diversification of its entire assets at the time.  No fee
is charged on redemption.  The redemption price may be more or less than the
shareholder's cost.  Redemption payments will be paid within seven days after
receipt of the written request therefor by the Fund, except that the right of
redemption may be suspended or payments postponed when permitted by applicable
law and regulations.

The net asset value of each Fund's shares is determined once daily at 4:00 as of
the close of the New York Stock Exchange on each day on which the Exchange is
open for trading.  The New York Stock Exchange is not open for trading on New
Year's Day, Presidents' Day, Good Friday, Memorial Day, Independence Day, Labor
Day, Columbus Day, Veteran's Day, Thanksgiving Day (including Friday) and
Christmas Day and on occasion is closed early or entirely due to weather or
other conditions.  The net asset value of each Fund share is the total net asset
value of the applicable Fund divided by the number of its shares outstanding.
The total net asset value of each Fund is determined by computing the value of
the total assets of the Fund and deducting total liabilities, including accrued
liabilities. It is the intention of MML Money Market Fund to maintain a per
share net asset value of $1.00, although this cannot be assured.

Except as to MML Money Market, the manner of determining the value of the total
assets of each Fund is briefly discussed below.  Equity securities are valued on
the basis of valuations furnished by a pricing service, authorized by the Board
of Trustees, which provides the last reported sale price for securities listed
on a national securities exchange, on the NASDAQ national market system, or are
unlisted.  If there is no reported sale price, the bid price of the prior trade
date will be used.  Long-term bonds are valued on the basis of valuations
furnished by a pricing service, authorized by the Board of Trustees, which
determines valuations taking into account appropriate factors such as
institutional-size trading in similar groups of securities, yield, quality,
coupon rate, maturity, type of issue, trading characteristics and other market
data.  Debt obligations with less than one year but more than sixty days to
maturity are valued on the basis of their market value, and debt obligations
having a maturity of sixty days or less are generally valued at amortized cost
when the Board of Trustees of MML Trust believes that amortized cost
approximates market value.  If acquired, preferred stocks will be valued on the
basis of their market value if market quotations are readily available.  In all
other cases, assets (including restricted securities) are valued at their fair
value as determined in good faith by the Board of Trustees of MML Trust,
although the actual calculations may be made by persons acting pursuant to the
direction of the Board.

MML Money Market's portfolio instruments are valued on the basis of amortized
cost which involves initially valuing an instrument at its cost and thereafter
making a constant amortiza-

                                       24
<PAGE>
 
tion to maturity of any discount or premium, regardless of the impact of changes
in market interest rates on the market value of the instrument.  While this
method provides certainty of valuation, it may result in periods in which the
value, as determined by amortized cost, is higher or lower than the price MML
Money Market would receive if it sold the instrument.  During periods of
declining interest rates, the daily yield on shares of MML Money Market computed
as described below may tend to be higher than a like computation made by a fund
with identical investments utilizing a method of valuation based upon market
prices and estimates of market prices for its portfolio instruments.  Thus, if
the use of amortized cost by MML Money Market resulted in a lower aggregate
portfolio value on a particular day, a prospective investor in MML Money Market
would be able to obtain a somewhat higher yield than would result from
investment in a fund utilizing market values, and existing investors in MML
Money Market would receive less investment income.  The converse would apply in
a period of rising interest rates.

The valuation of MML Money Market's portfolio instruments based upon their
amortized cost and the concomitant maintenance of MML Money Market Fund's per
share net asset value of $1.00 is permitted in accordance with Rule 2a-7 of the
Securities and Exchange Commission.  MML Money Market must maintain a dollar-
weighted average portfolio maturity of 90 days or less, generally may purchase
only instruments having remaining maturities of thirteen months (397 days) or
less, and invest only in United States dollar-denominated securities determined
by the Board of Trustees to be of high quality with minimal credit risks.

The Board of Trustees has established procedures designed to stabilize, to the
extent reasonably possible, MML Money Market's price per share as computed for
the purpose of sales and redemptions at $1.00.  Such procedures include review
of MML Money Market's portfolio holdings by the Board of Trustees, at such
intervals as they may deem appropriate, to determine the extent of any deviation
in MML Money Market's net asset value from $1.00 per share calculated by using
available market quotations, and whether such deviation may result in material
dilution or is otherwise unfair to investors or existing shareholders.  In the
event the Board of Trustees determines that such a deviation exists, it must
take such corrective action as it regards as necessary and appropriate,
including: the sale of portfolio instruments prior to maturity in order to
realize capital gains or losses or to shorten average portfolio maturity;
withholding dividends; redemptions of shares in kind; or establishing a net
asset value per share by using available market quotations, in which case the
net asset value could possibly be greater or less than $1.00 per share.

Since the net income of MML Money Market is declared as a dividend each time it
is determined, the net asset value per share of MML Money Market remains at
$1.00 per share immediately after each determination and dividend declaration.
Any increase in the value of a shareholder's investment in MML Money Market
representing the reinvestment of dividend income is reflected by an increase in
the number of shares of MML Money Market Fund in the shareholder's account,
which increase is recorded promptly after the end of each calendar month.

                                       25
<PAGE>
 
Futures contracts are valued based on the market price for the futures contract,
unless such price does not reflect the fair value of the contract, in which case
it will be valued by or under the direction of the Board of Trustees of MML
Trust.  When MML Managed Bond or MML Blend enters into a forward commitment to
purchase a security it will record the security as an asset which will be
marked-to-market daily to reflect the value of the security determined in the
manner set forth above.  The obligation to pay the purchase price of the
security will be a liability which remains fixed in amount.

                                 X. TAX STATUS

The Treasury Department has issued Regulations under Internal Revenue Code
Section 817(h), that pertain to diversification requirements for variable
annuity and life insurance contracts.  A variable contract based upon a separate
account will not receive favorable tax treatment as an annuity or life insurance
contract unless the separate account and underlying regulated investment company
investments are adequately diversified.  In determining whether a separate
account is adequately diversified, in certain circumstances the separate account
can look through to the assets of the regulated investment company in which it
has invested.

The Regulations require each of the four Fund's assets to be diversified so that
no single investment represents more than 55% of the value of the Fund's total
assets, no two investments represent more than 70% of the Fund's total assets,
no three investments represent more than 80% of the Fund's total assets and no
four investments represent more than 90% of the Fund's total assets.  A "safe
harbor" is available to a separate account if it meets the diversification tests
applicable to registered investment companies and not more than 55% of its
assets constitute cash, cash items, government securities and securities of
other registered investment companies.

The applicable Regulations treat all securities of the same issuer as a single
investment.  In the case of "government securities", each government agency or
instrumentality shall be treated as a separate issuer for the purpose of the
diversification test (although not for the purpose of the "safe harbor" test
described above).  MML Trust intends to comply with these diversification
requirements.  It is the policy of each Fund to comply, and in 1995 each Fund
did comply, with the provisions of the Internal Revenue Code applicable to
regulated investment companies.  As a result, none of the Funds will be subject
to federal income tax on any distributed net income or capital gains.

The Funds intend to declare capital gain and ordinary income dividends by the
end of each calendar year and to distribute such dividends no later than January
31 of the following year to the extent necessary to avoid the 4% excise tax on
undistributed regulated investment company income enacted by the Tax Reform Act
of 1986.  The 4% excise applies to the excess of the required distribution for
the calendar year over the amount treated as distributed for that year.  The
required distribution equals 98% of the Fund's ordinary income for the calendar
year plus 98% of its capital gain net income for the one year period ending
October 31 (or December 31, if the Fund so elects) and any shortfall of income
or gains from the prior year not previously so distributed.

                                       26
<PAGE>
 
                  XI. CERTAIN TAX AND ACCOUNTING INFORMATION

As previously indicated, it is the policy of each of the Funds to meet the
requirements of the Internal Revenue Code to qualify as a regulated investment
company under the federal tax law.  One of these requirements is that less than
30% of its gross income can be derived from gains from the sale or other
disposition of certain assets (including securities) held for or considered
under Internal Revenue Code rules to have been held for less than three months.
Accordingly, the Funds will be restricted in selling newly acquired positions,
engaging in certain option writing activities and certain hedging activities.

When a Fund writes a call option, an amount equal to the premium received by it
is included in its balance sheet as an asset and as an equivalent liability.
The amount of the liability is subsequently marked-to-market to reflect the
current market value of the option written.  The current market value of a
written option is the last sale price on the principal exchange on which such
option is traded or, in the absence of a sale, the mean between the last bid and
offering prices.  If an option which a Fund has written on an equity security
expires on its stipulated expiration date, or if the Fund enters into a closing
purchase transaction, it realizes a gain (or loss if the cost of a closing
purchase transaction exceeds the premium received when the option was sold)
without regard to any unrealized gain or loss on the underlying security, and
the liability related to such option is extinguished.

Special rules (including mark-to-market, straddle and wash sale rules) exist for
determining the timing of recognition of income or loss, the character of such
income or loss, and the holding periods of certain of the Fund's assets in the
case of certain transactions involving futures contracts, forward contracts and
options.  MML Trust will endeavor to make any available elections pertaining to
such transactions in a manner believed to be in the best interest of MML Trust.

                          XII. INVESTMENT PERFORMANCE

MML Money Market may advertise investment performance figures, including its
yield and its effective yield.  MML Money Market's yield will be calculated by
computing the net change, exclusive of capital changes, in the value of a
hypothetical pre-existing account having a balance of one share at the beginning
of a stated seven-day period and dividing the difference by the value of the
account at the beginning of the base period to obtain the base period return,
and then multiplying the base period return by (365/7).  The Fund's effective
yield will be calculated by computing the net change, exclusive of capital
changes, in the value of a hypothetical pre-existing account having a balance of
one share at the beginning of a stated seven-day period and dividing the
difference by the value of the account at the beginning of the base period to
obtain the base period return, and then compounding the base period return by
adding 1, raising the sum to a power equal to 365 divided by 7 and subtracting 1
from the result.

MML Equity, MML Managed Bond and MML Blend may advertise investment performance
figures, including yield.  Each Fund's yield will be based upon a stated 30-day
period and

                                       27
<PAGE>
 
will be computed by dividing the net investment income per share earned during
the period by the maximum offering price per share on the last day of the
period, according to the following formula:

                        YIELD = 2[((a-b)/cd + 1)/6/ - 1]

Where: a =   dividends and interest earned during the period.
       b =    expenses accrued for the period (net of reimbursements, if any).
       c =    the average daily number of shares outstanding during the period
              that were entitled to receive dividends.
       d =    the maximum offering price (which is the net asset value) per
              share on the last day of the period.

Each of the Funds may advertise its total return and its holding period return.
Total return quotations will be based upon a stated period and will be computed
by finding the average annual compounded rate of return over the stated period
that would equate an initial amount invested to the ending redeemable value of
the investment (assuming reinvestment of all distributions), according to the
following formula:

P(1 + T)/n/ = ERV   Where:  P = a hypothetical initial payment of $1,000.
                            T = average annual total return.
                            n = number of years.
                            ERV = ending redeemable value at the end of the
                            stated period of a hypothetical $1,000 payment made
                            at the beginning of the stated period.

Holding period return will be based upon a stated period and will be computed by
dividing the ending redeemable value of a hypothetical investment by the value
of the initial investment (assuming reinvestment of all distributions).  Each
investment performance figure will be carried to the nearest hundredth of one
percent.  These investment performance figures do not reflect charges imposed by
the separate investment accounts invested in the Funds which, if included, would
decrease the performance figures.

MML Equity Fund's yield, based on the 30-day period ended December 31, 1995 was
2.86%.  The Fund's total returns for the 1, 5, 10 and 15 year periods each ended

Fund's holding period returns for the 1, 5, 10 and 15 year periods each ended
December 31, 1995 were 31.13%, 107.39%, 263.37% and 722.99%, respectively.

MML Money Market Fund's yield for the seven-day period ended December 31, 1995
was 5.25% and its effective yield for such period was 5.39%.  The Fund's total
returns for the 1, 5, and 10 year periods each ended December 31, 1995 were
5.58%, 4.32%, and 5.92% respectively.  The Fund's total return for the period
beginning December 16, 1981 and ending December 31, 1995 was 6.97%.  The Fund's
holding period returns for the 1, 5 and 10 year

                                       28
<PAGE>
 
periods each ended December 31, 1995 were 5.58%, 23.57%, and 77.79%
respectively.  The Fund's holding period return for the period beginning
December 16, 1981 and ending December 31, 1995 was 157.53%.

MML Managed Bond Fund's yield, based on the 30-day period ended December 31,
1995, was 6.39%.  The Fund's total returns for the 1, 5, and 10 year periods
each ended December 31, 1995 were 19.14%, 9.92%, and 9.46% respectively.  The
Fund's total return for the period beginning December 16, 1981 and ending
December 31, 1995 was 10.93%.  The Fund's holding period returns for the 1, 5,
and 10 year periods each ended December 31, 1995 were 19.14%, 60.48%, and
146.88% respectively.  The Fund's holding period return for the period beginning
December 16, 1981 and ending December 31, 1995 was 329.02%.

MML Blend Fund's yield, based on the 30-day period ended December 31, 1995 was
3.98%. The Fund's total return for the 1, 5 and 10 year periods ended December
31, 1995 were 23.28%, 13.45%, and 12.31%, respectively.  The Fund's total return
for the period beginning February 3, 1984 and ending December 31, 1995 was
13.07%.  The Fund's holding period return for the 1, 5 and 10 year periods ended
December 31, 1995 were 23.28%, 87.93% and 219.29%, respectively.  The Fund's
holding period return for the period beginning February 3, 1984 and ending
December 31, 1995 was 331.58%.

Report Of Independent Accountants

To the Board of Trustees and Shareholders of
MML Series Investment Fund

We have audited the accompanying statement of assets and liabilities of each of
the Funds which comprise the MML Series Investment Fund (a Massachusetts
business trust), including the schedules of investments, as of December 31,
1995, and the related statement of operations for the year then ended, the
statement of changes in net assets for each of the two years in the period then
ended, and the financial highlights for each of the ten years in the period then
ended. These financial statements and financial highlights are the
responsibility of the Fund's management. Our responsibility is to express an
opinion on these financial statements and financial highlights based on our
audits.

We conducted our audits in accordance with generally accepted auditing
standards. 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, 1995 by correspondence with the custodian and brokers. An audit
also includes assessing the accounting principles used and significant estimates
made by management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide 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 each
of the Funds as of December 31, 1995, the results of their respective operations
for the year then ended, the changes in their respective net assets for each of
the two years in the period then ended, and the financial highlights for each of
the ten years in the period then ended, in conformity with generally accepted
accounting principles.

MML Series Investment Fund

Notes To Financial Statements


1.  History

MML Series Investment Fund (the "MML Trust") is registered under the
Investment Company Act of 1940 as a no-load, registered open end, diversified
management investment company. MML Equity Fund, MML Money Market Fund, MML
Managed Bond Fund and MML Blend Fund (the "Funds"") are the four series of
shares of the MML Trust. The MML Trust is organized under the laws of the
Commonwealth of Massachusetts pursuant to an Agreement and Declaration of Trust.

The MML Trust was established by Massachusetts Mutual Life Insurance Company
("MassMutual") for the purpose of providing vehicles for the investment of
assets of various separate investment accounts established by MassMutual and by
life insurance companies which are subsidiaries of MassMutual. Shares of the MML
Trust are not offered to the general public. MassMutual at December 31, 1995,
was the beneficial owner of 1.1% of MML Blend Fund's shares.

2.  Significant Accounting Policies

The following is a summary of significant accounting policies followed
consistently by each Fund in the preparation of the financial statements in
conformity with generally accepted accounting principles.

    A.  Investment Valuation

    Equity securities are valued on the basis of valuations furnished by a
    pricing service, authorized by the Board of Trustees, which provides the
    last reported sale price for securities listed on a national securities
    exchange, or on the NASDAQ national market system. If securities are
    unlisted, or there is no reported sale price, the bid price of the prior
    trade date will be used. Long-term bonds are valued on the basis of
    valuations furnished by a pricing service, authorized by the Board of
    Trustees, which determines valuations taking into account appropriate
    factors such as institutional-size, trading in similar groups of securities,
    yield, quality, coupon rate, maturity, type of issue, trading
    characteristics and other market data.

    For MML Equity Fund, MML Managed Bond Fund, and MML Blend Fund, short-term
    securities with more than sixty days to maturity from the date of purchase
    are valued at market and short-term securities having a maturity from the
    date of purchase of sixty days or less are valued at amortized cost. MML
    Money Market Fund's portfolio securities are valued at amortized cost in
    accordance with a rule of the Securities and Exchange Commission pursuant to
    which MML Money Market Fund must adhere to certain conditions. It is the
    intention of MML Money Market Fund to maintain a per share net asset value
    of $1.00.

    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. Premiums and discounts on short-term securities are amortized in
    determining interest income.

    The cost basis of long-term bonds is not adjusted for amortization of
    premium or accrual of discount since MML Managed Bond Fund and MML Blend
    Fund do not generally intend to hold such investments until maturity;
    however, the MML 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.

    C.  Federal Income Tax

    The MML Trust has established a policy for each of the Funds to comply with
    the provisions of the Internal Revenue Code applicable to regulated
    investment companies. As a result, the Funds will not be subject to federal
    income tax on any net investment income and any net capital gains to the
    extent they are distributed or are deemed to have been distributed to
    shareholders. Distributions are determined in accordance with income tax
    regulations which may differ from generally accepted accounting principles.
    These differences are primarily due to the deferral of wash sale losses, and
    paydowns on certain mortgage-backed securities. As a result, net investment
    income (loss) and net realized gain (loss) on investment transactions for a
    reporting period may differ significantly from distributions during such
    period. Accordingly, the Funds may periodically make reclassifications among
    certain of their capital accounts without impacting the net asset value of
    the Funds.

    D.  Forward Commitments

    Each Fund may purchase or sell securities on a  "when issued"  or delayed
    delivery or on a forward commitment basis. The Funds use forward commitments
    to manage interest rate exposure or as a temporary substitute for purchasing
    or selling particular debt securities. Forward commitments are not used for
    purposes of trading. Settlement for securities purchased on a forward
    commitment basis can take place a month or more after the date of the
    transaction. The Fund generally does not take delivery on these forward
    commitments, but such commitments are instead settled with offsetting
    transactions. When a forward commitment contract is closed, the Funds record
    a realized gain or loss. Forward commitments involve a risk of loss if the
    value of the security to be purchased declines prior to the settlement date.
    The Funds could also be exposed to loss if they can not close out their
    forward commitments because of an illiquid secondary market, or the
    inability of counterparties to perform. The Fund monitors exposure to ensure
    counterparties are credit worthy and concentration of exposure is minimized.
    The Funds instruct the custodian to segregate liquid high quality assets in
    a separate account with a current market value at least equal to the amount
    of its forward purchase commitments. The price of the underlying security
    and the date when the securities will be delivered and paid for are fixed at
    the time the transaction is negotiated. The value of the forward commitment
    is determined by management using a commonly accepted pricing model and
    fluctuates based upon changes in the value of the underlying security and
    market repo rates. Such rates equate the counterparty's cost to purchase and
    finance the underlying security to the earnings received on the security and
    forward delivery proceeds. The Funds record on a daily basis the unrealized
    appreciation/depreciation based upon changes in the value of the forward
    commitment. At December 31, 1995, the cost (value) of forward commitments to
    purchase securities amounted to $53,105,836 ($54,494,208) for the MML Blend
    Fund.

    E.  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.

3.  Capital Loss Carryforward

The accumulated net realized loss on investments for the MML Money Market Fund
results in a capital loss carryforward of $9,734 which is available for federal
income tax purposes to offset future capital gains. Of the total carryforward,
$485 expires December 31, 1997, $1,639 expires December 31, 1998, $1,204 expires
December 31, 2000, $201 expires December 31, 2001, $5,364 expires December 31,
2002 and $841 expires December 31, 2003.

The accumulated net realized loss on investments for the MML Managed Bond Fund
results in a capital loss carryforward of $840,829 which is available for
federal income tax purposes to offset future capital gains.  This carryforward
expires December 31, 2002.

4.  Investment Management Fee

MassMutual provides all investment advisory, management and administrative
services needed by the Funds. For acting as such, MassMutual receives a
quarterly fee from each Fund at the annual rate of .50% of the first
$100,000,000 of the average daily net asset value of each Fund, .45% of the next
$200,000,000, .40% of the next $200,000,000, and .35% of any excess over
$500,000,000.

MassMutual has entered into an investment sub-advisory agreement with Concert
Capital Management, Inc. ("Concert"), a wholly-owned subsidiary of Babson
Acquisition Corporation which is a controlled subsidiary of MassMutual. The
agreement provides that Concert manage the assets of MML Equity Fund and the
assets of the Equity Sector of MML Blend Fund. MassMutual pays Concert a
quarterly fee equal to an annual rate of .13% of the average daily net asset
value of MML Equity Fund and the Equity Sector of MML Blend Fund.

MassMutual has agreed, at least through April 30, 1997, to bear the expenses of
the Funds to the extent that the aggregate expenses (excluding each Fund's
management fee, interest, taxes, brokerage commissions and extraordinary
expenses) incurred during each Fund's fiscal year exceed .11% of the average
daily net asset value of each Fund for such year. For the year ended December
31, 1995, MassMutual was not required to reimburse the Funds for any expenses.

                          APPENDIX--Securities Ratings

This is a description of Standard & Poor's Corporation ("S&P") and Moody's
Investors Service, Inc. ("Moody's") commercial paper and bond ratings:

I. Commercial Paper Ratings:

S&P Commercial Paper Ratings--are graded into four categories, ranging from 'A'
for the highest quality obligations to 'D' for the lowest.  'A' Issues assigned
the highest rating are regarded as having the greatest capacity for timely
payment.  Issues in this category are delineated with the numbers 1, 2, and 3 to
indicate the relative degree of safety.  The A-1 and A-2 categories are
described as follows:

  "A-1":  This designation indicates that the degree of safety regarding timely
  payment is strong.  Those issues determined to possess extremely strong safety
  characteristics are denoted with a plus (+) sign designation.

  "A-2":  Capacity for timely payment on issues with this designation is
  satisfactory.  However, the relative degree of safety is not as high as for
  issues designated 'A-1'.

Moody's Commercial Paper Ratings--employs three designations, all judged to be
investment grade, to indicate the relative repayment ability of rated issuers.
The two highest designations are as follows:

  Prime-1:  Issuers rated Prime-1 (or related supporting institutions) have a
  superior ability for repayment of senior short-term debt obligations.  Prime-1
  repayment ability will often be evidenced by many of the following
  characteristics:

  .  Leading market positions in well-established industries.
  .  High rates of return on funds employed.
  .  Conservative capitalization structure with moderate reliance on debt and
     ample asset  protection.
  .  Broad margins in earnings coverage of fixed financial charges and high
     internal cash  generation.
  .  Well established access to a range of financial markets and assured sources
     of alternate liquidity.

  Prime-2:  Issuers rated Prime-2 (or related supporting institutions) have a
  strong ability for repayment of senior short-term promissory obligations.
  This will normally be evidenced by many of the characteristics cited above,
  but to a lesser degree.  Earnings trends and coverage ratios, while sound, may
  be more subject to variation.  Capitalization characteristics, while still
  appropriate, may be more affected by external conditions.  Ample alternate
  liquidity is maintained.



II.  Bond Ratings


                                      31


<PAGE>
 
S&P describes its four highest ratings for corporate debt as follows:

  A:  AAA--Debt rated AAA has the highest rating assigned by S&P. Capacity to
      pay interest and repay principal is extremely strong.

      AA--Debt rated AA has a very strong capacity to pay interest and repay
      principal and differs from the higher rated issues only in small degree.

      A--Debt rated A has a strong capacity to pay interest and repay principal
      although it is somewhat more susceptible to the adverse effects of changes
      in circumstances and economic conditions than debt in higher rated
      categories.

  B:  BBB--Debt rated BBB is regarded as having an adequate capacity to pay
      interest and repay principal.  Whereas it normally exhibits adequate
      protection parameters, adverse economic conditions or changing
      circumstances are more likely to lead to a weakened capacity to pay
      interest and repay principal for debt in this category than in higher
      rated categories.

The ratings from AA to CCC may be modified by the addition of a plus or minus
sign to show relative standing within the major rating categories.

Moody's describes its four highest corporate bond ratings as follows:

  Aaa--Bonds which are rated Aaa are judged to be of the best quality.  They
  carry the smallest degree of investment risk and are generally referred to as
  "gilt edged."  Interest payments are protected by a large or by an
  exceptionally stable margin and principal is secure.  While the various
  protective elements are likely to change, such changes as can be visualized
  are most unlikely to impair the fundamentally strong position of such issues.

  Aa--Bonds which are rated Aa are judged to be of high quality by all
  standards.  Together with the Aaa group they comprise what are generally known
  as high grade bonds.  They are rated lower than the best bonds because margins
  of protection may not be as large as in Aaa securities or fluctuation of
  protective elements may be of greater amplitude or there may be other elements
  present which make the long term risks appear somewhat larger than the Aaa
  securities.

  A--Bonds which are rated A possess many favorable investment attributes and
  are to be considered as upper medium grade obligations.  Factors giving
  security to principal and interest are considered adequate but elements may be
  present which suggest a susceptibility to impairment some time in the future.

  Baa--Bonds which are rated Baa are considered as medium grade obligations,
  (i.e., they are neither highly protected nor poorly secured).  Interest
  payments and principal security appear adequate for the present, but certain
  protective elements may be lacking or may be characteristically unreliable
  over any great length of time.  Such bonds lack outstanding investment
  characteristics and in fact have speculative characteristics as well.



Moody's applies numerical modifiers, 1, 2 and 3 in each generic rating
classification from Aa through B in its corporate bond rating system.  The
modifier 1 indicates that the security ranks in the higher end of its generic
rating category; the modifier 2 indicates a mid-range ranking; and the modifier
3


<PAGE>
 
indicates that the issue ranks in the lower end of its generic rating category.

S&P describes its below investment grade ratings for corporate debt as follows:

  BB,B,CCC,CC,C - Debt rated 'BB', 'B', 'CCC', 'CC' and 'C' is regarded, on
  balance, as predominantly speculative with respect to capacity to pay interest
  and repay principal in accordance with the terms of the obligation, 'BB'
  indicates the lowest degree of speculation and 'C' the highest degree of
  speculation.  While such debt will likely have some quality and protective
  characteristics, these are outweighed by large uncertainties or major risk
  exposures to adverse conditions.

  BB - Debt rated 'BB' has less near-term vulnerability to default than other
  speculative issues.  However, it faces major ongoing uncertainties or exposure
  to adverse business, financial, or economic conditions which could lead to
  inadequate capacity to meet timely interest and principal payments.  The 'BB'
  rating category is also used for debt subordinated to senior debt that is
  assigned an actual or implied 'BBB-' rating.

  B - Debt rated 'B' has a greater vulnerability to default but currently has
  the capacity to meet interest payments and principal repayments.  Adverse
  business, financial, or economic conditions will likely impair capacity or
  willingness to pay interest and repay principal.  The 'B' rating category is
  also used for debt subordinated to senior debt that is assigned an actual or
  implied 'BB' or 'BB-' rating.

  CCC - Debt rated 'CCC' has a currently identifiable vulnerability to default,
  and is dependent upon favorable business, financial, and economic conditions
  to meet timely payment of interest and repayment of principal.  In the event
  of adverse business, financial, or economic conditions, it is not likely to
  have the capacity to pay interest and repay principal.  The 'CCC' rating
  category is also used for debt subordinated to senior debt that is assigned an
  actual or implied 'B' or 'B-' rating.

  CC - The rating 'CC' is typically applied to debt subordinated to senior debt
  that is assigned an actual or implied 'CCC' rating.

  C - The rating 'C' is typically applied to debt subordinated to senior debt
  which is assigned an actual or implied 'CCC-' debt rating.  The 'C' rating may
  be used to cover a situation where a bankruptcy petition has been filed, but
  debt service payments are continued.

  C1 - The rating 'C1' is reserved for income bonds on which no interest is
  being paid.

  D - Debt rated 'D' is in payment default.  The 'D' rating category is used
  when interest payments or principal payments are not made on the date due even
  if the applicable grace period has not expired, unless S&P believes that such
  payments will be made during such grace period.  The 'D' rating also will be
  used upon the filing of a bankruptcy petition if debt service payments are
  jeopardized.


Moody's describes its below investment grade corporate bond ratings as follows:

  Ba - Bonds which are rated Ba are judged to have speculative elements; their
  future cannot be considered as well assured.  Often the protection of interest
  and principal payments may be very


<PAGE>
 
  moderate and thereby not well safeguarded during other good and bad times over
  the future.  Uncertainty of position characterizes bonds in this class.

  B - Bonds which are rated B generally lack characteristics of the desirable
  investment.  Assurance of interest and principal payments or of maintenance of
  other terms of the contract over any long period of time may be small.

  Caa - Bonds which are rated Caa are of poor standing.  Such issues may be in
  default or there may be present elements of danger with respect to principal
  or interest.

  Ca - Bonds which are rated Ca represent obligations which are speculative in a
  high degree.  Such issues are often in default or have other marked
  shortcomings.

  C - Bonds which are rated C are the lowest rated class of bonds and issues so
  rated can be regarded as having extremely poor prospects of ever attaining any
  real investment standing.

         ------------------------------------------------------------

At the date of this Post-Effective Amendment, Registrant did not, directly or
indirectly, control any person.  Registrant was organized by MassMutual
primarily for the purpose of providing a vehicle for the investment of assets of
various separate investment accounts established by MassMutual and life
insurance company subsidiaries of MassMutual.  The assets in such separate
accounts are, under state law, assets of the life insurance companies which have
established such accounts.  Thus, at any time MassMutual and its life insurance
company subsidiaries will own such outstanding shares of Registrant's series as
are purchased with separate account assets; however, where required to do so,
MassMutual and its subsidiaries will vote such shares only in accordance with
instructions received

in a manner consistent with Securities and Exchange Commission Release No. IC-
11330 so long as the interpretation of Section 17(h) and

17(i) of the Investment Company Act of 1940 set forth in such Release shall
remain in effect and be consistently applied.

Trustees and officers of Registrant are also indemnified by MassMutual pursuant
to its by-laws which apply to subsidiaries, including Registrant.  No
indemnification is provided with respect to any liability to any entity which is
registered as an investment company under the Investment Company Act of 1940 or
to the security holders thereof, where the basis for such liability is willful
misfeasance, bad faith, gross negligence or reckless disregard of the duties
involved in the conduct of office.

MassMutual's directors' and officers' liability insurance program, which covers
Registrant's Trustees and officers, consists of two distinct coverage.  The
first coverage reimburses MassMutual, subject to specified limitations, for
amounts which MassMutual is legally obligated to pay out under its
indemnification by-law, discussed above.  The second coverage directly protects
a Trustee or officer of Registrant against liability shareholder derivative and
similar lawsuits which are indemnifiable under the law.  There are, however,
specific acts giving rise to liability which are excluded from this coverage.
For example, no Trustee or officer is insured against personal liability for
libel or slander, acts of deliberate dishonesty, fines or penalties, illegal
personal profit or advantage at the expense of Registrant or its shareholders,
violation of employee benefit plans, regulatory statutes, and similar acts which
would traditionally run contrary to public policy and hence reimbursement by
insurance.

MassMutual's present insurance coverage has an overall limit of $45 million
annually ($15 million of which is underwritten by National Union Fire Insurance
Company, $15 million of which is underwritten by Executive Risk Indemnity, Inc.
and $15 million of which is underwritten by Sargasso Mutual Insurance Company).
There is a deductible of $200,000 per claim under the corporate coverage.  There
is no deductible for individual trustees or officers.

Insofar as indemnification for liabilities arising under the Securities Act of
1933 may be permitted to trustees, officers and controlling persons of
Registrant pursuant to the foregoing provisions, or otherwise, Registrant has
been advised that in the opinion of the Securities and Exchange Commission such
indemnification is against public policy as expressed in the Securities Act of
1933, and is,
<PAGE>
 
therefore, unenforceable.  In the event that a claim for indemnification against
such liabilities (other than the payment by Registrant of expenses incurred or
paid by a trustee, officer or controlling person of Registrant in the successful
defense of any action, suit or proceeding) is asserted by such trustee, officer
or controlling person in connection with the securities being registered,
Registrant will, unless in the opinion of its counsel the matter has been
settled by controlling precedent, submit to a court of appropriate jurisdiction
the question whether such indemnification by it is against public policy as
expressed in the Securities Act of 1933 and will be governed by the final
adjudication of such issue.

Item 28: Business and Other Connections of the Investment Adviser
- -----------------------------------------------------------------

MassMutual is the investment adviser for Registrant.  MassMutual conducts a life
insurance business in all states of the United States, the District of Columbia
and certain provinces of Canada.  MassMutual was incorporated in Massachusetts
in 1851.  As a mutual company, MassMutual belongs to its members.  The insurance
premiums which MassMutual receives are invested primarily in debt securities,
and the income which it receives from its investments in excess of the amounts
it must reserve for the payment of insurance benefits is credited to its
members.  It conducts no other business which is substantial in relation to its
business as a mutual life insurance company.  As of December 31, 1995, it had
total assets of approximately $50 billion and assets under management in excess
of $100 billion.  Effective February 29, 1996, Connecticut Mutual Life Insurance
Company merged into MassMutual.  Effective March 31, 1996, MassMutual sold its
group life and health insurance business.
