MassMutual Institutional Funds (the "Trust") is a professionally managed
investment company consisting of seven separate series of shares (the "Funds").
The Trust is designed to offer investors both the opportunity to pursue long-
term investment goals and the flexibility to respond to changes in their
investment objectives and economic and market conditions.  Each Fund has a
distinct investment objective.

     (1)  MASSMUTUAL PRIME FUND - Seeks to maximize current income to the extent
          consistent with liquidity and the preservation of capital by investing
          in a diversified portfolio of money market instruments. The Prime Fund
          is not a money market fund.

     (2)  MASSMUTUAL SHORT-TERM BOND FUND - Seeks to achieve a high total rate
          of return primarily from current income while minimizing fluctuations
          in capital values by investing primarily in a diversified portfolio of
          short-term investment grade fixed income securities.

     (3)  MASSMUTUAL CORE BOND FUND - Seeks to achieve a high total rate of
          return consistent with prudent investment risk and the preservation of
          capital by investing primarily in a diversified portfolio of
          investment grade fixed income securities.

     (4)  MASSMUTUAL BALANCED FUND - Seeks to achieve a high total rate of
          return over an extended period of time consistent with the
          preservation of capital values by investing in a diversified portfolio
          of equity securities, fixed income securities and money market
          instruments.

     (5)  MASSMUTUAL VALUE EQUITY FUND - Seeks to achieve long-term growth of
          capital and income by investing primarily in a diversified portfolio
          of equity securities of larger well-established companies.

     (6)  MASSMUTUAL SMALL CAP VALUE EQUITY FUND - Seeks to achieve long-term
          growth of capital and income by investing primarily in a diversified
          portfolio of equity securities of smaller companies.

     (7)  MASSMUTUAL INTERNATIONAL EQUITY FUND - Seeks to achieve a high total
          rate of return over the long term by investing in a diversified
          portfolio of foreign and domestic securities, primarily common stocks
          and securities having the characteristics of common stocks, such as
          convertible securities.

    
This Prospectus sets forth concisely the information about the Funds and the
Trust that a prospective investor should know before investing.  Please read it
carefully and retain it for future reference.  Certain additional information
about the Funds and the Trust is contained in a Statement of Additional
Information dated May 1, 1997, which has been filed with the Securities and
Exchange Commission and is incorporated herein by reference. This additional
information is available without charge by writing to the Secretary, MassMutual
Institutional Funds, 1295 State Street, Springfield, MA 01111.     

    
Massachusetts Mutual Life Insurance Company ("MassMutual" or the "Adviser") is
the investment manager to each of the Funds.  David L. Babson and Company, Inc.
("Babson") is the investment sub-adviser to the Value Equity Fund, the Small
Cap Value Equity Fund and the Value Equity Sector of the Balanced Fund.
HarbourView Asset Management Corporation ("HarbourView") is the investment sub-
adviser to the International Equity Fund.  Babson and HarbourView are
hereinafter collectively referred to as the "Sub-Adviser".     

    
Each of the Funds offers four classes of shares.  Class 1, Class 2 and Class?3
shares of each Fund are intended to be purchased primarily by defined
contribution plans that satisfy the qualification requirements of Section 401(a)
of the Internal Revenue Code of 1986, including 401(k) plans, profit sharing
plans, money purchase plans and target benefit plans. Class 1, Class 2 and Class
3 shares may be offered to defined benefit plans, to other retirement and
employee benefit plans, such as tax sheltered annuities and non-qualified plans,
IRAs, and to other institutional or sophisticated investors. Class 4 shares of
each Fund are available only to separate investment accounts of MassMutual in
which corporate qualified plans, including defined contribution plans and
defined benefit plans, and certain governmental plans are permitted to invest
pursuant to the issuance of group annuity contracts.

THE TRUST

The Trust is an open-end, diversified management investment company (a "mutual
fund") designed to offer investors both the opportunity to pursue long-term
investment goals and the flexibility to respond to changes in their investment
objectives and economic and market conditions.  The Trust consists of seven
separate series of shares (the "Funds"), each having four classes of shares.

    
     .  Class 1, Class 2 and Class 3 shares of each Fund are offered primarily
        to employer-sponsored defined contribution plans that satisfy the
        qualification requirements of Section 401(a) of the Internal Revenue
        Code of 1986, as amended (the "Code"). Defined contribution plans -
        which establish an individual account for each plan participant -
        include 401(k) plans, profit sharing plans, money purchase plans and
        target benefit plans. Class 1, Class 2 and Class 3 shares may be offered
        to defined benefit plans, to other retirement and employee benefit
        plans, such as tax sheltered annuities and non-qualified plans, IRAs,
        and to other institutional or sophisticated investors.     

    
     .  Class 4 shares of each Fund are available only to separate investment
        accounts ("SIAs") of MassMutual in which corporate qualified plans,
        including defined contribution plans and defined benefit plans, and
        certain governmental plans are permitted to invest pursuant to the
        issuance of group annuity contracts.     

    
The Trust is organized under the laws of the Commonwealth of Massachusetts as a
Massachusetts business trust pursuant to an Agreement and Declaration of Trust
dated May 28, 1993, as amended from time to time (the ``Declaration of Trust").
Each share of a Fund represents an investment in that Fund's portfolio of
securities.  The value of an investment in a Fund will vary as the value of the
underlying portfolio increases or decreases.  Dividends paid for a class of the
Fund will vary in relation to the pro rata return received from the Fund's
investments and the expenses each class incurs.     

    
The Board of Trustees of the Trust is generally responsible for management of
the business and affairs of the Trust.  Trustees formulate the general policies
of the Trust and the Funds, approve contracts and authorize Trust officers to
carry out the decisions of the Board.  As Adviser and Sub-Advisers to the Funds,
MassMutual, Babson and HarbourView may be considered part of the management of
the Trust.  For more information concerning the management of the Trust,
reference should be made to the Statement of Additional Information.     

INVESTMENT OBJECTIVES AND POLICIES OF THE FUNDS

Each Fund has a separate investment objective, which may not be changed without
the vote of a majority of that Fund's outstanding voting shares./1/  There can
be no assurance that a Fund will achieve its investment objective; the success
of a Fund depends to a great extent upon changes in market conditions.

(1)  MASSMUTUAL PRIME FUND

THE INVESTMENT OBJECTIVE OF THE PRIME FUND IS TO MAXIMIZE CURRENT INCOME TO THE
EXTENT CONSISTENT WITH LIQUIDITY AND THE PRESERVATION OF CAPITAL BY INVESTING IN
A DIVERSIFIED PORTFOLIO OF MONEY MARKET INSTRUMENTS.

The Fund invests in high quality debt instruments having a remaining maturity
not exceeding 397 days.  It is the Fund's policy to invest in the following
types of short-term instruments:

     (a)  Commercial paper and obligations of corporate issuers that at the date
          of acquisition are rated in one of the two highest ratings of at least
          one nationally recognized statistical rating organization ("NRSRO")
          or, if unrated, are judged by MassMutual to be of equivalent
          quality./2/

     (b)  U.S. Government Securities./3/

     (c)  Bank participation certificates that represent interests in all or
          part of specific bank loans, provided that at the date of acquisition
          (1) they have a remaining maturity of 397 days or less; and (2) each
          of the underlying loans is made to an issuer of securities rated in
          one of the two highest ratings of at least one NRSRO or, if unrated,
          are judged by MassMutual to be of equivalent quality.

     (d)  Certificates of deposit and bankers' acceptances of banks and savings
          and loan associations having deposits of at least $1 billion as of
          their most recently published financial statements.


_____________
/1/ As used in this Prospectus, a majority of the outstanding voting shares of
any Fund means the lesser of (a) 67% of that Fund's outstanding shares present
at a meeting of shareholders if more than 50% of the outstanding shares are
present in person or by proxy, or (b) more than 50% of that Fund's outstanding
shares.

    
/2/ For a description of the ratings of two NRSROs, Standard & Poor's Ratings
Group ("S&P") and Moody's Investors Service, Inc. ("Moody's"), see the Appendix
to the Statement of Additional Information. For example, the two highest ratings
of Moody's for commercial paper are P-1 and P-2.     

/3/ See the Glossary for a definition of U.S. Government Securities.

                                       21
<PAGE>
 
     (e)  Obligations of foreign issuers, payable in U.S. dollars, provided that
          no such investment will be made if as a result more than 25% of the
          Fund's total assets would be invested in such securities.

    
The Fund will make portfolio investments primarily in response to changing
economic and money market conditions and trends.  Trading activity is expected
to be low.  It is anticipated, however, that from time to time the Fund 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 management deems
that such transactions will improve the yield or the quality of the portfolio.
The Fund is not a money market fund as defined in Rule 2a-7 under the Investment
Company Act of 1940 (the ``1940 Act'').  The portfolio of the Fund is managed by
Mary E. Wilson, Senior Managing Director of MassMutual, with which she has been
associated since 1982.     

(2)  MASSMUTUAL SHORT-TERM BOND FUND

THE INVESTMENT OBJECTIVE OF THE SHORT-TERM BOND FUND IS TO ACHIEVE A HIGH TOTAL
RATE OF RETURN PRIMARILY FROM CURRENT INCOME WHILE MINIMIZING FLUCTUATIONS IN
CAPITAL VALUES BY INVESTING PRIMARILY IN A DIVERSIFIED PORTFOLIO OF SHORT-TERM
INVESTMENT GRADE FIXED INCOME SECURITIES.

The Fund invests in investment grade fixed income securities.  Investment grade
fixed income securities are securities that at the date of acquisition are rated
in one of the four highest ratings of at least one NRSRO or, if unrated, are
judged by MassMutual to be of equivalent quality./4/  For example, the Fund may
invest in the following types of debt instruments:

     (a)  Corporate securities.

     (b)  U.S. Government Securities.

     (c)  Obligations 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 as a result more than 25% of the Fund's total assets would
          be invested in such securities.

     (d)  Obligations (including certificates of deposit, time deposits or
          bankers' acceptances) of U.S. or Canadian chartered banks having total
          deposits in excess of $1 billion, U.S. branches of foreign banks
          having total deposits in excess of $1 billion, U.S. savings and loan
          associations having total deposits in excess of $1 billion, and
          Eurodollar certificates of deposit issued by foreign branches of U.S.
          banks having total deposits in excess of $1 billion.

     (e)  Publicly traded debt securities issued or guaranteed by a national or
          state bank or bank holding company (as defined in the Federal Bank
          Holding Company Act, as amended) that at the date of acquisition are
          rated in one of the three highest ratings of at least one NRSRO or, if
          unrated, are judged by MassMutual to be of equivalent quality, and
          certificates of deposit of such banks.

     (f)  Commercial paper that at the date of investment is rated in the two
          highest ratings of at least one NRSRO or, if unrated, is judged by
          MassMutual to be of equivalent quality.

     (g)  Bank participation certificates that represent interests in all or
          part of specific bank loans, provided that at the date of investment
          each of the underlying loans is made to an issuer of securities rated
          in one of the two highest short-term debt ratings of at least one
          NRSRO or, if unrated, are judged by MassMutual to be of equivalent
          quality.

     (h)  Certificates of deposit and bankers' acceptances of banks and savings
          and loan associations having deposits of at least $1 billion as of
          their most recently published and audited financial statements.

     (i)  Securities of foreign issuers (other than those listed in (c) or (d)
          above) that meet credit quality requirements similar to those above,
          provided that no such investment will be made if as a result more than
          25% of the Fund's total assets would be invested in such securities.

    
Under normal market conditions, the Fund generally will have an average
effective portfolio Duration of no more than three years.  Portfolio Duration
changes may be accomplished primarily through the reinvestment of cash flows and
selective trading.  See the Glossary for a definition of Duration .  Neither
market timing nor interest rate anticipation methods are employed in managing
the Fund.  The portfolio of the Fund is managed by Ronald E. Desautels, Managing
Director of MassMutual, with which he has been associated since 1989.     

(3)  MASSMUTUAL CORE BOND FUND

THE INVESTMENT OBJECTIVE OF THE CORE BOND FUND IS TO ACHIEVE A HIGH TOTAL RATE
OF RETURN CONSISTENT WITH PRUDENT INVESTMENT RISK AND THE PRESERVATION OF
CAPITAL BY INVESTING PRIMARILY IN A DIVERSIFIED PORTFOLIO OF INVESTMENT GRADE
FIXED INCOME SECURITIES.

The Fund invests in investment grade, publicly traded, readily marketable, fixed
income securities of such maturities as MassMutual deems appropriate from time
to time in light


____________
/4/ For example, the four highest ratings of Moody's for debt obligations are
Aaa, Aa, A, and Baa (including Baa3).

of market conditions and prospects. Investment grade fixed income securities are
securities that at the date of acquisition are rated in one of the four highest
ratings of at least one NRSRO or, if unrated, are judged by MassMutual to be of
equivalent quality. For example, the Fund may invest in the following types of
debt instruments:

     (a)  Corporate securities.

     (b)  U.S. Government Securities.

     (c)  Obligations 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 as a result more than 25% of the Fund's total assets would
          be invested in such securities.

     (d)  Obligations (including certificates of deposit, time deposits or
          bankers' acceptances) of U.S. or Canadian chartered banks having total
          deposits in excess of $1 billion, U.S. branches of foreign banks
          having total deposits in excess of $1 billion, U.S. savings and loan
          associations having total deposits in excess of $1 billion, and
          Eurodollar certificates of deposit issued by foreign branches of U.S.
          banks having total deposits in excess of $1 billion.

     (e)  Publicly traded debt securities issued or guaranteed by a national or
          state bank or bank holding company (as defined in the Federal Bank
          Holding Company Act, as amended) having a rating within the three
          highest ratings as determined by at least one NRSRO or, if unrated,
          are judged by MassMutual to be of equivalent quality, and certificates
          of deposit of such banks.

    
     (f)  Securities of foreign issuers (other than those listed in (c) or (d)
          above) that at the date of acquisition are rated in one of the four
          highest ratings of at least one NRSRO or, if unrated, are judged by
          MassMutual to be of equivalent quality, provided that no such
          investment will be made if as a result more than 25% of the Fund's
          total assets would be invested in such securities.     

    
Normally, the Fund's portfolio Duration will range from four to seven years.
Portfolio Duration changes will be accomplished primarily through the
reinvestment of cash flows and selective trading.  See the Glossary for a
definition of Duration.  The portfolio of the Fund is managed by Mary E. Wilson,
Senior Managing Director of MassMutual, with which she has been associated since
1982.     

(4)  MASSMUTUAL BALANCED FUND

THE INVESTMENT OBJECTIVE OF THE BALANCED FUND IS TO ACHIEVE A HIGH TOTAL RATE OF
RETURN OVER AN EXTENDED PERIOD OF TIME CONSISTENT WITH THE PRESERVATION OF
CAPITAL VALUES BY INVESTING IN A DIVERSIFIED PORTFOLIO OF EQUITY SECURITIES,
FIXED INCOME SECURITIES AND MONEY MARKET INSTRUMENTS.

The Fund invests in three market sectors:

    
     THE PRIME SECTOR - The Prime Sector invests in accordance with the
     investment objective and policies of the Prime Fund.     

    
     THE CORE BOND SECTOR - The Core Bond Sector invests in accordance with the
     investment objective and policies of the Core Bond Fund.     

    
     THE VALUE EQUITY SECTOR - The Value Equity Sector invests in accordance
     with the investment objective and policies of the Value Equity Fund.     

    
The Fund adjusts 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 Fund
expects that such adjustments normally will be made in a gradual manner over a
period of time.  Under normal circumstances at least 25% of the Fund's total
assets will be invested in senior fixed income securities (including short-term
money market instruments).  In addition, under normal circumstances, no
investment will be made that would result in more than 35% of the Fund's net
assets being invested in the Prime Sector, more than 35% in the Core Bond Sector
or more than 65% in the Value Equity Sector.  In unusual circumstances, the Fund
may invest up to 70% of its total assets in the Equity Sector or up to 50% of
its total assets in the Bond Sector.  The portfolio of the Fund is managed by
committee.     

(5)  MASSMUTUAL VALUE EQUITY FUND

THE INVESTMENT OBJECTIVE OF THE VALUE EQUITY FUND IS TO ACHIEVE LONG-TERM GROWTH
OF CAPITAL AND INCOME BY INVESTING PRIMARILY IN A DIVERSIFIED PORTFOLIO OF
EQUITY SECURITIES OF LARGER WELL-ESTABLISHED COMPANIES.

The Fund invests primarily in common stocks, securities convertible into common
stocks, and other equity securities (such as warrants and stock rights) which
are normally cash dividend-paying and listed on a national securities exchange
or traded in the over-the-counter market.  The issuers of securities in which
the Fund will invest generally are companies with market capitalizations in
excess of $2 billion and a history of operations of five years or more.

    
The Fund utilizes a value-oriented, risk-averse strategy in making investment
decisions.  As such, investments are made in securities of companies which, in
the opinion of Babson, 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      

                                       23
<PAGE>
 
    
Stock Price Index (the "S&P 500 Stock Index"). Consideration also is given to
securities of companies whose current prices do not adequately reflect, in the
opinion of Babson, the ongoing business value of the enterprise. MassMutual is
the Fund's adviser, its Sub-Adviser is Babson. The Fund's portfolio is managed
by James W. MacAllen, Executive Vice President and Chief Investment Officer of
Babson. Mr. MacAllen has been associated with Babson since January 1, 1996.
During 1996, Mr. MacAllen was also Senior Vice President of Concert Capital
Management, Inc. (``Concert Capital"), and, as such, managed the portfolio of
the Fund. (Concert Capital merged with and into Babson effective as of December
31, 1996.) Prior to that, Mr. MacAllen was associated with Hagler, Mastrovita
and Hewitt and prior to that was President and Chief Investment Officer of
Wilmington Capital Management.    

(6)  MASSMUTUAL SMALL CAP VALUE EQUITY FUND

THE INVESTMENT OBJECTIVE OF THE SMALL CAP VALUE EQUITY FUND IS TO ACHIEVE LONG-
TERM GROWTH OF CAPITAL AND INCOME BY INVESTING PRIMARILY IN A DIVERSIFIED
PORTFOLIO OF EQUITY SECURITIES OF SMALLER COMPANIES.

The Fund invests primarily in common stocks, securities convertible into common
stocks and other equity securities (such as warrants and stock rights) which are
issued by companies with a market capitalization of less than $750 million and
which are listed on a national securities exchange or traded in the over-the-
counter market.

    
The Fund utilizes a value-oriented, risk-averse strategy in making investment
decisions.  As such, investments are made in securities of companies that, in
the opinion of Babson, are of high quality or possess a unique product, market
position or operating characteristics which result in above-average levels of
profitability or superior growth potential and are attractively valued in the
marketplace.  Traditional fundamental research techniques are employed to
determine investment quality and growth potential, emphasizing each issuer's
historic financial performance, balance sheet strength, management capability
and competitive position.  Valuation parameters are examined to determine the
attractiveness of individual securities.  On average, the Fund's holdings will
have price/earnings ratios and price/book value ratios below those of the S&P
500 Stock Index.  Consideration also is given to securities of companies whose
current prices do not adequately reflect the ongoing business value of the
enterprise.     

    
The Fund may purchase securities with above-average volatility relative to
indices like the S&P 500 Stock Index.  While such volatility frequently may
involve the opportunity for greater gain, it also generally involves greater
risk of loss and, as a result, the Fund's shares are suitable only for those
investors who are in a financial position to assume such risk.  MassMutual is
the Fund's adviser, its Sub-Adviser is Babson.  The Fund's portfolio is managed
by George P. Ulrich, Senior Vice President of Babson.  Mr. Ulrich has been
associated with Babson since 1996, Concert Capital from 1993 through 1996 and
with MassMutual from 1984 to 1993.     

(7)  MASSMUTUAL INTERNATIONAL EQUITY FUND

THE INVESTMENT OBJECTIVE OF THE INTERNATIONAL EQUITY FUND IS TO ACHIEVE A HIGH
TOTAL RATE OF RETURN OVER THE LONG TERM BY INVESTING IN A DIVERSIFIED PORTFOLIO
OF FOREIGN AND DOMESTIC EQUITY SECURITIES.

The Fund invests primarily in common stocks and securities having the
characteristics of common stocks, such as convertible securities, warrants and
stock rights. The Fund generally will have at least 75% of its total assets
invested in foreign securities, including securities of foreign issuers
represented by American Depository Receipts or traded in the U.S. over-the-
counter market or listed on a U.S. securities exchange.  Under normal market
conditions, the Fund's assets will be invested in securities traded in markets
in at least three different countries, excluding the United States.  In an
uncertain market or economic environment when it would be appropriate to
maintain a defensive position, the Fund may invest up to 100% of its assets in
debt securities, such as rated or unrated bonds and debentures, cash equivalents
and preferred stocks.  It is expected that short-term debt securities (i.e.,
those maturing in one year or less from the date of purchase) will be emphasized
for defensive or liquidity purposes, since such securities usually may be
disposed of quickly at prices not involving significant losses.  When
circumstances warrant, securities may be sold without regard to the length of
time held, although short-term trading may increase brokerage costs borne by the
Fund.

The share price of the International Equity Fund will reflect the movements of
both the prices of the portfolio securities and the currencies in which the
securities are denominated.  Depending upon the extent of the Fund's investments
abroad, changes in the relative value of the U.S. dollar to the securities'
denominated currencies may have a positive or negative impact on the Fund's
share price.

    
The Fund's investment policies involve special risks.  Risks of investing in
foreign securities include foreign taxation, changes in currency rates or
currency blockage, currency exchange costs, and differences between domestic and
foreign legal, accounting, auditing, brokerage and economic standards.  See
"Foreign Securities" in the Statement of Additional Information for further
discussion of the possible risks and rewards of investing in foreign securities.
MassMutual is the Fund's adviser, its Sub-Adviser is HarbourView. The portfolio
of the Fund is managed by a committee composed of HarbourView investment
professionals.     

                                       24

INVESTMENT PRACTICES OF THE FUNDS AND RELATED RISKS

The Funds may invest in a wide range of investments and engage in various
investment-related transactions and practices.  These practices are pursuant to
non-fundamental policies and therefore may be changed by the Board of Trustees
without the consent of shareholders.  Some of the more significant practices are
discussed below.

REPURCHASE AGREEMENTS AND REVERSE REPURCHASE AGREEMENTS

Each Fund may engage in repurchase agreements and reverse repurchase agreements.
A repurchase agreement is a contract pursuant to which a Fund agrees to purchase
a security and simultaneously agrees to resell it at an agreed-upon price at a
stated time, thereby determining the yield during the Fund's holding period.  A
reverse repurchase agreement is a contract pursuant to which a Fund agrees to
sell a security and simultaneously agrees to repurchase it at an agreed-upon
price at a stated time.  For a more detailed description of repurchase
agreements and reverse repurchase agreements and related risks, see the
Statement of Additional Information.

SECURITIES LENDING

Each Fund may make loans of portfolio securities of not more than 33% of its
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 the
Adviser or Sub-Adviser to be in good standing.

HEDGING INSTRUMENTS AND DERIVATIVES

Each Fund may buy or sell forward contracts and other similar instruments and
may engage in foreign currency transactions (collectively referred to as
"hedging instruments" or "derivatives"), as more fully discussed in the
Statement of Additional Information.  Derivatives normally are used by a
portfolio manager 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 its unrealized losses; and (c) manage a Fund's
exposure to changing security prices.  Derivatives also may be used to establish
a position in the debt or equity securities markets as a temporary substitute
for purchasing or selling particular debt or equity securities and to manage the
effective maturity or duration of fixed income securities in a Fund's portfolio.
The Funds will not use derivatives for speculative purposes.

(1)  Forward Contracts - Each Fund may purchase or sell securities on a "when
     issued" or delayed delivery basis or may purchase or sell securities 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.
     While a Fund also may enter into forward contracts with the initial
     intention of acquiring securities for its portfolio, it may dispose of a
     commitment prior to settlement if the Adviser or Sub-Adviser deem it
     appropriate to do so.

(2)  Currency Transactions - The International Equity Fund may engage in foreign
     currency transactions with counterparties in order to hedge the value of
     portfolio holdings denominated in particular currencies against
     fluctuations in relative value. The Short-Term Bond Fund, the Core Bond
     Fund and the Core Bond Sector of the Balanced Fund may invest in foreign
     securities that are not denominated in U.S. dollars only if the Fund
     contemporaneously enters into a foreign currency transaction to hedge the
     currency risk associated with the particular foreign security.

Certain limitations apply to the use of forward contracts by the Funds.  For
example, a Fund will not enter into a forward contract if as a result more than
25% of its total assets would be held in a segregated account covering such
contracts.  For more information about forward contracts and currency
transactions and the extent to which tax considerations may limit a Fund's use
of such instruments, see the Statement of Additional Information.

There can be no assurance that the use of hedging instruments and derivatives by
a Fund will assist it in achieving its investment objective.  Risks inherent in
the use of these instruments include: (a) the risk that interest rates and
securities prices will not move in the direction anticipated; (b) the imperfect
correlation between the prices of a forward contract and the price of the
securities being hedged; and (c) the fact that skills needed to use these
strategies are different from those needed to select portfolio securities.  As
to forward contracts, the risk exists that the counterparty to the transaction
will be incapable of meeting its commitment, in which case the desired hedging
protection may not be obtained and the Fund may be exposed to risk of loss.  As
to currency transactions, risks exist that purchases and sales of currency and
related instruments can be negatively affected by government exchange controls,
blockages, and manipulations or exchange restrictions imposed by governments
which could result in losses to the Fund if it is unable to deliver or receive
currency or funds in settlement of obligations.  It also could cause hedges it
has entered into 

                                       25
<PAGE>
 
to be rendered useless, resulting in full currency exposure as well as incurring
transaction costs.

RESTRICTED AND ILLIQUID SECURITIES

None of the Funds currently expect to invest in restricted or illiquid
securities.  However, each Fund may invest not more than 15% of its net assets
in illiquid securities. These policies do not limit the purchase of securities
eligible for resale to qualified institutional buyers pursuant to Rule 144A
under the Securities Act of 1933, as amended, provided that such securities are
determined to be liquid by the Board of Trustees, or by the Adviser or Sub-
Adviser pursuant to Board-approved guidelines.  If there is a lack of trading
interest in particular Rule 144A securities, a Fund's holdings of those
securities may be illiquid, resulting in the possibility of undesirable delays
in selling these securities at prices representing fair value.

FOREIGN SECURITIES

Investments in foreign securities offer potential benefits not available from
investing solely in securities of domestic issuers, such as the opportunity to
invest in foreign issuers that appear to offer growth potential, or to invest in
foreign countries with economic policies or business cycles different from those
of the United States or foreign stock markets that do not move in a manner
parallel to U.S. markets, thereby reducing fluctuations in portfolio value.

Investments in foreign securities entail certain risks, such as the possibility
of one or more of the following:  imposition of dividend or interest withholding
or confiscatory taxes; currency blockages or transfer restrictions;
expropriation, nationalization, military coups or other adverse political or
economic developments; less government supervision and regulation of securities
exchanges, brokers and listed companies, and the difficulty of enforcing
obligations in other countries.  Certain markets may require payment for
securities before delivery.  A Fund's ability and decisions to purchase and sell
portfolio securities may be affected by laws or regulations relating to the
convertibility of currencies and repatriation of assets.  Further, it may be
more difficult for a Fund's agents to keep currently informed about corporate
actions which may affect the prices of portfolio securities.  Communications
between the United States and foreign countries may be less reliable than within
the United States, thus increasing the risk of delayed settlements of portfolio
transactions or loss of certificates for portfolio securities.

PORTFOLIO MANAGEMENT

    
MassMutual, Babson and HarbourView may use trading as a means of managing the
portfolios of the Funds in seeking to achieve their investment objectives.
Transactions will occur when the Adviser or Sub-Adviser 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 the Adviser's or Sub-Adviser's
ability to evaluate particular securities and anticipate relevant market
factors, including interest rate trends and variations from such trends.  If
such evaluations and expectations prove to be incorrect, a Fund's income or
capital appreciation may be reduced and its capital losses may be increased.
The portfolio turnover rates for the Funds for the fiscal years ended December
31, 1996 and 1995, respectively, are as follows:  Short-Term Bond Fund 61% and
114%; Core Bond Fund 54% and 104%; Balanced Fund 26% and 23%; Value Equity Fund
13% and 16%; Small Cap Value Equity Fund 28% and 28%; and International Equity
Fund 58% and 121%.  High turnover in any Fund could result in additional
brokerage commissions to be paid by the Fund.     

CASH POSITIONS

Each Fund may hold cash or cash equivalents to provide for 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 in
investment grade debt securities, government obligations, or money market
instruments.

INDUSTRY DIVERSIFICATION

As a general rule, a Fund will not acquire securities of issuers in any one
industry (as determined by the Board of Trustees) if as a result more than 25%
of the value of the total assets of the Fund would be invested in such industry,
with the following exceptions:

(1)  There is no limitation for U.S. Government Securities.

(2)  In the case of the Prime Fund and the Short-Term Bond Fund, there is no
     industry concentration limitation for certificates of deposit and bankers'
     acceptances.

CERTAIN DEBT SECURITIES

While the Funds, except for the Prime Fund, may invest in investment grade debt
securities that are rated in the fourth highest rating category by at least one
NRSRO (e.g., Baa3 by Moody's) or, if unrated, are judged by MassMutual to be of
equivalent quality, such securities have speculative characteristics, are
subject to greater credit risk, and may be subject to greater market risk than
higher rated investment grade securities.

FUNDAMENTAL INVESTMENT RESTRICTIONS

For a description of fundamental investment restrictions of the Funds which may
not be changed without the affirmative vote of a majority of the outstanding
voting shares of the Fund, reference should be made to the Statement of
Additional Information.

HOW TO PURCHASE, EXCHANGE, CONVERT AND REDEEM SHARES

FEATURES AND ELIGIBILITY REQUIREMENTS OF EACH CLASS

No front-end or deferred sales charge is imposed on the Trust's shares.
Therefore, 100% of an Investor's money is invested in the Fund or Funds of its
choice.

CLASS 1, CLASS 2 AND CLASS 3 SHARES

These shares may be purchased only through registered broker-dealers.

Pursuant to a 12b-1 Plan adopted by the Trust, Class 1 and Class 2 shares of
each Fund are subject to distribution/service fees (12b-1 fees), as follows:

(1)  Class 1 shares pay a distribution fee at the annual rate of .40% and a
     service fee at the annual rate of .25% of the Fund's aggregate average net
     assets attributable to the Class 1 shares.

(2)  Class 2 shares pay a distribution fee at the annual rate of .15% of the
     Fund's aggregate average net assets attributable to the Class 2 shares.

The Trust's Distributor receives distribution fees and may reallow all or a
portion of them as dealer discounts and brokerage commissions to dealers,
including MML Investors Services, Inc. ("MMLISI"), a wholly owned subsidiary of
MassMutual.  From time to time, dealers who receive dealer discounts and
brokerage commissions from the Trust's Distributor may reallow all or a portion
of them to other dealers or brokers.  The service fees will be paid to
MassMutual.

Class 3 shares of each Fund are "no load" because they are not subject to front-
end or deferred sales charges or to any distribution/service fees.

No initial investment minimum applies to Class 1 shares.  Investors in Class 2
and Class 3 shares must meet certain eligibility requirements.  An initial
Investor may purchase Class 2 shares of a Fund only if the net asset value of
such shares equals at least $2 million.  An initial Investor may purchase Class
3 shares of a Fund only if the net asset value of such shares equals at least
$10 million.  For purposes of determining whether a Plan Investor has satisfied
the initial investment minimum with respect to Class 2 or Class 3 shares, all
assets invested with MassMutual and/or in the Trust for that Plan will be
recognized  - except for life insurance assets.  For purposes of this
determination, a Plan also shall include those plans established by entities of
the Plan Sponsor that satisfy Section 414(b), (c), (m), or (o) of the Internal
Revenue Code of 1986, as amended, provided that all such Plans have common
trustees.  Additionally, the Plan Investor will be deemed to have satisfied the
$2 million and $10 million requirements if the Plan Investor certifies that at
least such amounts are available for transfer and will be transferred from the
Plan to MassMutual and/or the Trust no later than six months from the date of
initial purchase.  Alternatively, an initial Investor may purchase Class 2 or
Class 3 shares if the Investor's employee retirement benefit plan with
MassMutual has 400 or more Participants (with respect to Class 2) or 750 or more
Participants (with respect to Class 3).  All subsequent investments by an
Investor will be of the same Class of shares already held until shares are
converted from one Class to another (see ``Converting From Class 1 to Class 2
Shares or Class 2 to Class 3 Shares'').

CLASS 4 SHARES

Class 4 shares may be purchased only by separate investment accounts of
MassMutual ("SIA Investors").  SIA Investors purchase Class 4 shares directly
from the Fund without a front-end or deferred sales charge and pay no
distribution or service fees.

PURCHASE OF SHARES

    
Shares of the Trust are offered on each day the New York Stock Exchange ("NYSE")
is open for trading (a "Business Day").  Purchase orders received by the
Transfer Agent from MassMutual (as an agent of the Distributor) on a Business
Day prior to the close of the NYSE (normally, 4:00 p.m. Eastern Time) will be
processed based on that day's closing net asset value.     

    
Purchase orders must be placed in writing with MassMutual (as an agent of the
Distributor) at its home office and must be accompanied by sufficient funds.
Acceptable methods of payment include checks, federal funds wires, and automated
clearing house transactions ("ACH").  MassMutual, on behalf of the Distributor,
will not transmit a purchase order to the Trust's Transfer Agent until
MassMutual has determined that the purchase order is in good form.  Generally, a
purchase order will be determined by MassMutual to be in good form if such
order:  (a) includes all information and documentation necessary to make
appropriate Investor, Plan, trust and/or Plan Participant (if applicable)
allocations to the various Funds and/or Separate Accounts; and (b) is received
by MassMutual at its home office prior to the close of the NYSE.  Purchase
orders by wire will be in good form only upon receipt by MassMutual of (i) the
funds, deposited to the appropriate MassMutual account, and (ii) a confirmation
of the wire receipt.  Any order to purchase Fund shares which is received by
MassMutual after the close of the NYSE on a Business Day will be transmitted to
the Trust's Transfer Agent on the next Business Day.  For more specific
information regarding what information and documentation are necessary for
MassMutual to determine that a purchase order is in good form with respect to a
particular plan, Plan Investors should refer to Plan Documents./5/

/5/ See the Glossary for a definition of Plan Documents.

                                       27
<PAGE>
 
The sale of Trust shares will be suspended during any period when the
determination of net asset value is suspended.  The sale of Trust shares also
may be suspended by the Board of Trustees whenever the Board determines that it
is in the Trust's best interest to do so.  The Trust, in its complete
discretion, may reject any order for purchase of its shares.

EXCHANGE PRIVILEGES AND PROCEDURES

Investors have the privilege of exchanging shares of one Fund for the same class
of shares of another Fund, subject to the provisions of Plan Documents and
applicable state insurance laws.  However, exchanges may be restricted or
refused by a Fund if, in the opinion of the Adviser, (i) an Investor has engaged
in excessive trading, (ii) the Fund receives or anticipates simultaneous orders
affecting significant portions of the Fund's assets, or (iii) a pattern of
exchanges coincides with a "market timing" strategy that might be disruptive to
the Fund.  Each Fund also reserves the right to refuse exchange purchases by any
person or group of persons, if, in the Adviser's judgment, the Fund would be
unable to invest the funds effectively in accordance with its investment
objectives and policies, or otherwise potentially would be adversely affected.
The Trust reserves the right on 60 days' written notice to modify or terminate
the exchange privilege.  Furthermore, any exchange limits imposed by a Fund may
be modified, in the sole discretion of the Fund, for Plan Investors so that the
Fund's exchange privileges are consistent with Plan or group annuity contract
exchange limits as set forth in Plan Documents and Department of Labor
regulations.  Plan Investors and Plan Participants should refer to Plan
Documents and related materials to determine what, if any, exchange limitations
apply to them.

Exchange requests must be delivered in writing to MassMutual at its home office.
Any exchange will involve the redemption of shares and the purchase of shares in
another Fund on the basis of the next calculated net asset value per share of
each Fund after the exchange request is received by the Trust's Transfer Agent
from MassMutual.  MassMutual will not transmit exchange requests to the Trust's
Transfer Agent until MassMutual has determined that the request is in good
form./6/


CONVERTING FROM CLASS 1 TO CLASS 2 SHARES OR CLASS 2 TO CLASS 3 SHARES

Investors that hold Class 1 shares may qualify for an automatic conversion to
Class 2 shares and Investors that hold Class 2 shares may qualify for an
automatic conversion to Class 3 shares.  Specifically, twice each year, as of
March 1 and September 1 or, (if not a Business Day, then the next Business Day),
MassMutual will determine whether a Class 1 or Class 2 Investor meets the
eligibility requirements for the purchase of Class 2 or Class 3 shares,
respectively.  If the Investor meets the eligibility requirements of Class 2 or
Class 3, its Class 1 or Class 2 shares automatically will convert on March 31 or
September 30, as applicable, (or, if not a Business Day, then the next Business
Day) into Class 2 or Class 3 shares, using that day's net asset value.

Class 1 or Class 2 Investors whose shares convert to Class 2 or Class 3 shares
will be subject to lower distribution/service fees (in the case of Class 2) or
no distribution/service fees (in the case of Class 3).

REDEEMING SHARES

Redemption requests must be in writing and sent to MassMutual at its home
office.  Each Fund redeems its shares at their net asset value as next computed
after receipt by the Transfer Agent of a request for redemption from MassMutual.
MassMutual will not transmit redemption requests to the Trust's Transfer Agent
until MassMutual has determined that the request is in good form.  No contingent
deferred sales charge or any other fee is charged on redemptions from any Class
of shares.  Redemption payments will be made within seven days after receipt of
the written request therefor by the Trust, except that the right of redemption
may be suspended or payments postponed when permitted by applicable law and
regulations.  When redemption is requested of shares recently purchased by
check, payment may be delayed until the check has been collected, which may take
up to 15 days from receipt of the check.

INVESTMENT MANAGER AND SUB-ADVISERS

INVESTMENT MANAGER

    
MassMutual is the investment manager to the Funds and is responsible for
providing all necessary investment management and administrative services.
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
insurance business in all states of the United States, the District of Columbia,
Puerto Rico and certain Provinces of Canada.  As of December 31, 1996,
MassMutual, together with its subsidiaries, had assets in excess of $55.7
billion and assets under management in excess of $130.8 billion.

cific instructions as may be given by the Board of Trustees of the Trust.
MassMutual may, at its expense, employ sub-advisers to manage the investments of
the Funds.

The Trust, on behalf of each Fund, pays MassMutual an investment advisory fee
monthly for the investment advisory services performed and the facilities
furnished at an annual rate of the average daily net assets of that Fund as
follows:

(1) .45% for the Prime Fund, the Short-Term Bond Fund, the Core Bond Fund, the
    Balanced Fund and the Value Equity Fund.

(2) .55% for the Small Cap Value Equity Fund.

(3) .85% for the International Equity Fund.

    
For the fiscal year ended December 31, 1996, MassMutual received fees (after
giving effect to a fee waiver) based upon each Fund's average daily net assets,
as follows:  Prime Fund .41%; Short-Term Bond Fund .41%; Core Bond Fund .41%;
Balanced Fund .41%; Value Equity Fund .40%; Small Cap Value Equity Fund .51%;
International Equity Fund .78%. The fee waiver terminated on May 1, 1997.     

In addition, MassMutual has entered into a separate administrative services
agreement for each Fund pursuant to which MassMutual is obligated to provide all
necessary administrative and shareholder services and to bear some Class
expenses, such as federal and state registration fees, printing and postage.
The Funds are responsible for certain other expenses including brokerage, taxes,
interest, fees and expenses of non-interested trustees, legal fees, custody and
audit fees.  MassMutual may, at its expense, employ others to supply all or any
part of the services to be provided to the Funds pursuant to the administrative
services agreements.  The Trust, on behalf of each Fund, pays MassMutual an
administrative services fee monthly for the administrative services performed at
annual rates of the average daily net assets of the applicable class of shares
of the Fund which range from .55% to .59% for Class 1 shares, .50% to .54% for
Class 2 shares, .31% to .44% for Class 3 shares and .0782% to .0972% for Class 4
shares.  Refer to ``Expense Information'' for more detailed information.

INVESTMENT SUB-ADVISERS

    
MassMutual has entered into investment sub-advisory agreements with Babson and
HarbourView.  These agreements provide that (1) Babson will manage the
investment and reinvestment of the assets of the Value Equity Fund, the Small
Cap Value Equity Fund and the Value Equity Sector of the Balanced Fund, and (2)
HarbourView will manage the investment and reinvestment of the assets of the
International Equity Fund.     

    
MassMutual pays Babson a fee equal to an annual rate of .13% of the average
daily net asset value of the Value Equity Fund, .13% of the average daily net
asset value of the Value Equity Sector of the Balanced Fund and .25% of the
average daily net asset value of the Small Cap Value Equity Fund.  MassMutual
pays HarbourView a fee equal to an annual rate of .50% of the average daily net
asset value of the International Equity Fund.     

    
Babson is a wholly-owned subsidiary of DLB Acquisition Corporation (``DLB
Acquisition"), a controlled subsidiary of MassMutual. Babson is a registered
investment adviser that has been providing investment counseling to institutions
and individuals for over 50 years. As of December 31, 1996, Babson had over $7.6
billion of assets under management. Babson serves as investment sub-adviser to
the MML Equity Fund and the Equity Sector of MML Blend Fund of MML Series
Investment Fund, a registered investment company managed by MassMutual.     

    
HarbourView is a wholly owned subsidiary of OppenheimerFunds, Inc. which is a
wholly owned subsidiary of Oppenheimer Acquisition Corporation ("OAC"), a
holding company owned in part by senior management of OAC and ultimately
controlled by MassMutual by virtue of its ownership of approximately 86% of
OAC's voting stock.     

    
HarbourView has operated as an investment adviser since 1986.  As of April 10,
1997, HarbourView managed assets of approximately $700 million.  HarbourView
manages the assets of the International Equity Fund and certain separate
investment accounts of MassMutual.     

DISTRIBUTOR, TRANSFER AGENT, SHAREHOLDER SERVICING AGENT, CUSTODIAN

OppenheimerFunds Distributor, Inc. ("Oppenheimer") acts as Distributor to each
Fund.  MML Investors Services, Inc. ("MMLISI") serves as Sub-Distributor for
each Fund.  Investors Bank & Trust Company ("Investors Bank") serves as each
Fund's Sub-Administrator, Transfer Agent, and Custodian.  MassMutual ultimately
has a controlling interest in Oppenheimer.  MMLISI is a wholly owned subsidiary
of MassMutual.  Both Oppenheimer and MMLISI may serve as distributors of
securities issued by other investment companies.  As Custodian, Investors Bank
has custody of the Funds' securities, maintains certain financial and accounting
books and records, and generally assists in all aspects of the administration of
the Funds.  Neither Oppenheimer, MMLISI nor Investors Bank assists in or is
responsible for the investment decisions and policies of the Funds.  MassMutual
provides the Funds with certain shareholder services pursuant to its
administrative services agreements.

DESCRIPTION OF SHARES

The Trust is a series company which is authorized to issue shares in separate
series of multiple classes.  The Trust may issue an unlimited number of shares
of multiple classes, in one or more series as the Trustees may authorize, with
or with-

                                       29
<PAGE>
 
out par value as the Trustees may prescribe. Each share of a particular class of
a Fund represents an equal proportionate interest in that Fund with each other
share of the same class, none having priority or preference over another. Each
Fund is preferred over all other Funds in respect of the assets allocated to
that Fund. Each share of a particular class of a Fund is entitled to a pro rata
share of any distributions declared in respect of that class and, in the event
of liquidation, a pro rata share of the net assets of that class remaining after
satisfaction of outstanding liabilities. When issued, shares are fully paid and
nonassessable and have no preemptive or subscription rights. Under the Trust's
Declaration of Trust, the Board of Trustees is authorized to create new series
and classes without shareholder approval. Shares of each Fund entitle their
holder to one vote for each dollar (or proportionate fractional vote for each
fraction of a dollar) of net asset value per share of each Fund or class for
each share held as to any matter on which such shares are entitled to vote.

The Trust is not required to hold annual meetings of shareholders.  Special
meetings may be called for such purposes as electing Trustees, voting on
management agreements and distribution plans, and with respect to such
additional matters relating to the Trust as may be required by the Trust's
Declaration of Trust and the 1940 Act.

HOW FUND SHARES ARE PRICED

    
The net asset value (closing price) of each class of each Fund's shares is
determined once daily as of the close of trading on the NYSE (currently 4:00
p.m. Eastern Time) on each day on which the Exchange is open for trading.  Net
asset value for a class of shares is determined by dividing the total market
value of a Fund's portfolio investments and other assets attributable to that
class, less any liabilities, by the total outstanding shares of the class.     

Securities which are traded on a national securities exchange or on the NASDAQ
national market system generally are valued at the last sale price.  Debt
securities normally are valued at the last reported bid price on the primary
market for those securities.  To the extent authorized by the Board of Trustees,
portfolio securities may be valued by a pricing service that determines values
based on market transactions for normal institutional-size trading units.  Money
market obligations having a maturity of 60 days or less are generally valued at
amortized cost when the Board of Trustees of the Trust believes that amortized
cost approximates market value.  In all other cases, assets and other securities
for which no quotations are readily available (including restricted securities)
are 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.

A dealer or other organization selling shares of Classes 1, 2, or 3 may receive
different levels of compensation for selling one particular class of shares over
another.  Certain shares of the Funds, which may be purchased through the
Distributor at the net asset value per share next determined after receipt of a
purchase request in good order, are subject to sales charges which are part of
the 12b-1 fees set forth and expressed on an annual basis (see "Expense
Information").  The fees are charged on a daily basis and paid over to the
Distributor monthly.  Based on a 365-day year, the daily sales charge portion of
the 12b-1 fee, expressed as a gross percentage of total Fund assets at the end
of the day rounded to the nearest 1/10,000 of percent, is 0.0011% for Class 1
shares and 0.0004% for Class 2 shares.  The same percentages would apply when
expressing the sales charge portion as a percentage of the amount available for
investment the next day net of the fee.

No sales charges are associated with the sale of shares of Class 3 or Class 4.
However, registered representatives who are not employees of MassMutual may
receive certain cash compensation from MassMutual in consideration of their
sales of Class 3 shares of the Funds.  If investment in the Funds is equal to or
less than $10 million, the fee will be 0.10% of such investment.  If the
investment in the Funds exceeds $10 million, the fee will be the sum of 0.10% of
the first $10 million invested and 0.05% on amounts in excess of $10 million.

DISTRIBUTIONS AND TAXATION

Each Fund intends to continue to qualify as a regulated investment company under
Subchapter M of the Internal Revenue Code of 1986 (the "Code").  As a regulated
investment company, a Fund will not be subject to federal income taxes on its
ordinary income and net realized capital gain distributed to its shareholders.
In general, a Fund that fails to distribute at least 98% of such income and gain
in the calendar year in which earned will be subject to a 4% excise tax on the
undistributed amount.

Many Investors, including most tax qualified Plan Investors, may be eligible for
preferential federal income tax treatment on distributions received from a Fund
and dispositions of Fund shares.  This Prospectus does not attempt to describe
in any respect such preferential tax treatment.  Any prospective Investor that
is a trust or other entity eligible for special tax treatment under the Code
that is considering purchasing shares of a Fund, either directly or indirectly
through a life insurance company separate account, should consult its tax
advisers about the federal, state and local tax consequences particular to it,
as should persons considering whether to have amounts held for their benefit by
such trusts or other entities invested in shares of a Fund.  Investors that do
not receive preferential tax treatment are subject to federal income taxes on
distributions received in respect of their shares.  Distributions of the Fund's
ordinary income and short-term capital gain are taxable to the shareholder as
ordinary income whether received in cash or additional shares.  Designated long-
term capital gain distributions are taxable as long-term capital gain whether
distributed in cash or additional shares and regardless of how long the Investor
has owned shares of the Fund; however, a loss recognized from the sale of Fund
shares held for six months or less will be treated as a long-term capital loss
to the extent of long-term capital gains distributions.  Certain designated
dividends may 

                                       30
<PAGE>
 
be eligible for the dividends-received deduction for corporate shareholders.
Investors should consult with their tax advisers for additional information
concerning the federal, state and local tax consequences of purchasing shares of
a Fund.

Dividends from net investment income and distributions of any net realized
capital gains of each Fund are declared and paid annually or at other times as
necessary to meet regulatory requirements.  Distributions shall be paid in full
and fractional shares of the applicable Class of the applicable Fund at net
asset value on the first Business Day after the record date for the
distribution, unless, subject to such terms and conditions of the underlying
Plan Documents, the Investor has elected to receive dividend payments in cash.

INVESTMENT PERFORMANCE

The Trust commenced operations on October 3, 1994 subsequent to the transfer of
assets by each of seven SIAs to the Fund having corresponding investment
objectives, policies and limitations in exchange for shares of such Fund.  While
the SIAs continue to exist, their assets consist solely of shares of the
corresponding Fund.  Except for the seed capital provided by MassMutual, each
Fund's portfolio of investments on October 3, 1994 was the same as the portfolio
of the corresponding SIA immediately prior to the transfer.

    
The SIAs are not registered investment companies as they each are exempt from
registration under the 1940 Act.  Since, in a practical sense, the SIAs
constitute ``predecessors'' of the Funds, the Trust calculates the performance
for each Class of each Fund for periods commencing prior to the transfer of the
SIA assets to the Funds by including the corresponding SIA's total return
adjusted to reflect the deduction of fees and expenses applicable to each Class
as stated in the Fee Table of the Trust's initial prospectus which was effective
October 3, 1994 (i.e., adjusted to reflect anticipated expenses, net of
management fee waivers).  These fees and expenses include sales charges (if any
should be imposed), Rule 12b-1 fees and, in the case of Class 4, any charges at
the SIA level. See ``Expense Information" regarding the elimination of the
management fee waiver.     

The quoted performance data includes the performance of the SIAs for periods
before the Trust's Registration Statement became effective.  As noted above, the
SIAs were not registered under the 1940 Act and thus were not subject to certain
investment restrictions that are imposed by the 1940 Act.  If the SIAs had been
registered under the 1904 Act, the SIAs performance might have been adversely
affected.  Employee benefit plans that invest plan assets in the SIAs may be
subject to certain charges as set forth in their respective Plan Documents.
Total return figures would be lower for the period if they reflected these
charges.

Each of the Funds from time to time may advertise certain investment performance
figures.  These figures are based on historical earnings but past performance
data is not necessarily indicative of future performance of the Funds.  All
performance information with respect to Class 4 shares will be provided net of
the Fund and SIA expenses.  Each of the Funds may quote yield in conformance
with current Securities and Exchange Commission guidelines.  Currently, the
yield for each Fund refers to the net investment income earned by the Fund over
a 30-day period, as defined 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 as 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
(as 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.

GLOSSARY

BUSINESS DAY: each day the New York Stock Exchange is open for trading.

CURRENCY TRANSACTIONS: include forward currency contracts, exchange listed
currency futures, exchange listed and OTC options on currencies, and currency
swaps.  A forward currency contract involves a privately negotiated obligation
to purchase or sell (with delivery generally required) a specific currency at a
future date, which may be any fixed number of days from the date of the contract
agreed upon by the parties, at a price set at the time of the contract.  A
currency swap is an agreement to exchange cash flows based on the notional
difference among two or more currencies and operates similarly to an interest
rate swap.

DURATION: indicates how interest rate changes will affect a debt instrument's
price.

FOREIGN SECURITIES: include debt, equity, and hybrid instruments, obligations
and securities of foreign issuers, including governments of countries other than
the United States and companies organized under the laws of countries other than
the United States that are traded on foreign securities exchanges or foreign
over-the-counter markets.  Foreign securities also include securities of foreign
issuers (i) represented by American Depository Receipts, (ii) traded in the
United States over-the-counter markets, or (iii) listed on a U.S. securities
exchange.

INVESTOR: includes a plan sponsor, plan fiduciary, trust, institutional
investor, and/or insurance company separate investment account that purchases
shares of the Trust and is hereinafter referred to as Investor or collectively
referred to as Investors.  An Investor that is a separate investment account of
MassMutual is referred to as an SIA Investor to the extent it invests in the
Trust.  Investors that are purchasing shares of a Fund on behalf of a Plan are
sometimes referred to as Plan Investors.  The term Investor does not include a
Plan Participant.

    
NRSRO: means a nationally recognized statistical rating organization.  For a
description of the ratings of two NRSROs, Standard & Poor's Ratings Group
("S&P") and Moody's Investors Service, Inc. ("Moody's"), see Appendix A to the

                              GENERAL INFORMATION
                              -------------------

MassMutual Institutional Funds (the "Trust") is a professionally managed, open-
end, diversified management investment company (a "mutual fund").  The Trust is
a series fund consisting of seven separate series: (1) MassMutual Prime Fund,
(2) MassMutual Short-Term Bond Fund, (3) MassMutual Core Bond Fund, (4)
MassMutual Balanced Fund, (5) MassMutual Value Equity Fund, (6) MassMutual Small
Cap Value Equity Fund, and (7) MassMutual International Equity Fund (each
individually referred to as a "Fund" or collectively as the "Funds").

    
The Trust is organized under the laws of the Commonwealth of Massachusetts as a
Massachusetts business trust pursuant to an Agreement and Declaration of Trust
dated May 28, 1993, as amended from time to time (the ``Declaration of Trust").
Additional series may be created by the Trustees from time to time.  The
investment manager for each Fund is Massachusetts Mutual Life Insurance Company
("MassMutual").  The investment sub-adviser for the Value Equity Fund, the Small
Cap Value Equity Fund and the Equity Sector of the Balanced Fund is David L.
Babson and Company, Inc. (``Babson").  The investment sub-adviser for the
International Equity Fund is HarbourView Asset  Management Corporation
("HarbourView").  Babson and HarbourView are each indirect subsidiaries of
MassMutual.  MassMutual, Babson and HarbourView are sometimes referred to herein
as the "advisers."     

                         ADDITIONAL INVESTMENT POLICIES
                         ------------------------------

    
Each Fund has a distinct investment objective which it pursues through separate
investment policies, as described in the Prospectus and below.  The investment
objective, fundamental investment policies and fundamental investment
restrictions of a Fund may not be changed without the vote of a majority of that
Fund's outstanding shares (which, under the Investment Company Act of 1940 (the
"1940 Act") and the rules thereunder and as used in this Statement of Additional
Information and in the Prospectus, means the lesser of (1) 67% of the shares of
that Fund present at a meeting if the holders of more than 50% of the
outstanding shares of that Fund are present in person or by proxy, or (2) more
policies and restrictions without shareholder approval.     

The following discussion, when applicable, elaborates on the presentation of
each Fund's investment policies contained in the Prospectus.  For a description
of the ratings of corporate debt securities and money market instruments in
which the various Funds may invest, reference should be made to the Appendix.

PRIME FUND

An instrument in which the Prime Fund may invest will be considered to be short-
term if its remaining maturity on the date of its purchase is 397 days or less.
In the case of a variable or floating rate obligation, the remaining maturity
will be deemed to be the period remaining until the next readjustment of the
interest rate or until maturity, whichever is less.  In the case of an
obligation with a demand feature, the remaining maturity will be deemed to be
the period remaining until the principal amount may be recovered through the
demand provision or until the next readjustment of the interest rate or until
maturity, whichever is the shortest.

Certain money market instruments are available only in relatively large
denominations, and others may carry higher yields if purchased in relatively
large denominations.  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
Prime Fund's investment restrictions limit the percentage of the Fund's assets
which may be invested in certain industries or in securities of any issuer.
Accordingly, if the Fund has relatively small net assets and net cash flow from
sales and redemptions of shares, the Fund may be unable to invest in money
market instruments paying the highest yield available at a particular time.

SHORT-TERM BOND FUND

The Fund's duration management strategy currently utilizes a quantitative, risk-
averse discipline that balances generating a high total rate of return primarily
from current income with minimizing fluctuations in capital values.  The
duration of the portfolio will be lengthened by extending average maturities
when sufficient additional yield can 

                                      B-3
<PAGE>
 
be obtained. Conversely, the duration will be shortened when adequate
compensation for the additional risk associated with longer maturities cannot be
realized.

CORE BOND FUND

The Core Bond Fund's duration management strategy is to match (within 10%) the
duration of the Lehman Brothers Government/Corporate Bond Index.  MassMutual
seeks to add value compared to this index through the use of sector rotation,
yield curve management and asset selection.  Neither market timing nor interest
rate anticipation methods are employed in managing the Fund.

INTERNATIONAL EQUITY FUND

The Trustees are authorized to determine what constitutes a "foreign security"
and to modify any such definition as they deem appropriate.  Opportunities for
long-term capital appreciation will be stressed.

Currency Transactions - The Fund may engage in currency transactions with
counterparties in order to hedge the value of portfolio holdings denominated in
particular currencies against fluctuations in relative value.

FIXED INCOME SECURITIES

While the Prime Fund invests in high quality securities and the Short-Term Bond
Fund, the Core Bond Fund and the Core Bond Sector of the Balanced Fund invest in
investment grade securities, investment in these Funds is not without risk.  The
debt securities in which the Funds invest may not offer as high a yield as may
be achieved from lower quality instruments having less safety.  If the Prime
Fund, the Short-Term Bond Fund or the Core Bond Fund 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.  If an investment of the Short-Term Bond Fund or the Core Bond Fund
is downgraded below investment-grade level, the adviser will normally dispose of
such security in a reasonable period of time.  In special circumstances the
adviser may determine that it is in the Fund's best interest to continue to hold
the security.

WARRANTS AND RIGHTS

A warrant typically gives the holder the right to purchase underlying stock at a
specified price for a designated period of time.  Warrants may be a relatively
volatile investment.  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.  Rights are similar to warrants, but normally have a
short duration and are distributed directly by the issuer to its shareholders.
Warrants and rights have no voting rights, receive no dividends, and have no
rights to the assets of the issuer.

The Equity Sector of the Balanced Fund, the Value Equity Fund, the Small Cap
Value Equity Fund and the International Equity Fund may each invest up to 5% of
the value of their respective assets in warrants in an effort to build a
position in the underlying common stocks and, of such 5%, no more than 2% may be
invested in warrants that are not listed on the New York Stock Exchange or the
American Stock Exchange.

REPURCHASE AND REVERSE REPURCHASE AGREEMENTS

In a repurchase agreement transaction, a Fund acquires a security from, and
simultaneously resells it to, an approved vendor (a U.S. commercial bank or the
U.S. branch of a foreign bank, or a broker-dealer which has been designated a
primary dealer in government securities and which must meet the credit
requirements set by the Trust's Board of Trustees from time to time) for
delivery on an agreed-upon future date.  The resale price exceeds the purchase
price by an amount that reflects an agreed-upon interest rate effective for the
period during which the repurchase agreement is in effect.  The majority of
these agreements run from day to day, and delivery pursuant to the resale
agreement typically will occur within one to five days of the purchase.
Repurchase agreements are considered "loans" under the 1940 Act, collateralized
by the underlying security.  A Fund's repurchase agreements require that at all
times while the repurchase agreement is in effect, the value of the collateral
must equal or exceed the repurchase price to fully collateralize the loan.
Additionally, a Fund's adviser will impose creditworthiness requirements to
confirm that the vendor is financially sound 

                                      B-4
<PAGE>
 
and will continuously monitor the collateral's value. However, 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.

    
A reverse repurchase agreement is a contract pursuant to which a Fund agrees to
sell a security and simultaneously agrees to repurchase it at an agreed-upon
price at a stated time.  A Fund engaging in reverse repurchase agreements will
maintain a segregated account with its custodian containing cash or liquid
securities, 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 Restriction (2) under
"Fundamental Investment Restrictions."     

CERTAIN DEBT SECURITIES

Some U.S. Government Securities are backed by the full faith and credit of the
U.S. Government; others are secured by the right of the issuer to borrow from
the U.S. Treasury; while others are supported only by the credit of the issuing
agency or instrumentality.  There can be no assurance that the U.S. Government
will pay interest and principal on securities on which it is not legally
obligated to do so.

The Funds will limit their investments in certificates of deposit and bankers'
acceptances to U.S. dollar denominated obligations of U.S. banks and savings and
loan associations, London branches of U.S. banks ("Eurodollar obligations") and
U.S. branches of foreign banks ("Yankeedollar obligations").  In the case of
foreign banks, the $1 billion deposit requirement will be computed using
exchange rates in effect at the time of the banks' most recently published
financial statements.  Eurodollar obligations and Yankeedollar obligations will
not be acquired if as a result more than 25% of a Fund's net assets would be
invested in such obligations.  Obligations of foreign banks and of foreign
branches of U.S. banks 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 banks and foreign branches of U.S. banks may
provide less public information than, and may not be subject to the same
accounting, auditing and financial recordkeeping standards as, domestic banks.

SECURITIES LENDING

A Fund may make loans of portfolio securities of not more than 33% of its net
assets taken at current market value to attempt to increase its income.  Under
applicable regulatory requirements and securities lending agreements (which are
subject to change), the loan collateral must, on each business day, be at least
equal to the value of the loaned securities and must consist of cash, bank
letters of credit or securities of the U.S. Government (or its agencies or
instrumentalities), or other cash equivalents in which the Fund is permitted to
invest.  The terms of a Fund's loans must also meet certain tests under the
Internal Revenue Code and permit the Fund to reacquire loaned securities on five
business days' notice or in time to vote on any important matter.

HEDGING INSTRUMENTS AND DERIVATIVES

The Funds currently may use the hedging instruments and derivatives discussed
below.  In the future, a Fund may employ hedging instruments and strategies that
are not currently contemplated but which may be developed, to the extent such
investment methods are consistent with the Fund's investment objective, legally
permissible and adequately disclosed.

    
(1) FORWARD CONTRACTS - Each Fund may purchase or sell securities 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.  While
a Fund also may enter into forward contracts with the initial intention of
acquiring securities for its portfolio, it may dispose of a commitment prior to
settlement if MassMutual deems it appropriate to do so.  The Funds may realize
short-term gains or losses upon the sale of forward contracts.  If a Fund enters
into a forward contract, it will establish a segregated account with its
custodian consisting of cash or liquid securities, having a current market value
equal to or greater than the aggregate amount of that Fund's commitment under
forward contracts (that is, the purchase price of the underlying      

                                      B-5
<PAGE>
 
security on the delivery date). 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. A Fund will not enter into a forward contract if as a result
more than 25% of its total assets would be held in a segregated account covering
such contracts.

(2) CURRENCY TRANSACTIONS -Each Fund may engage in currency transactions with
counterparties in order to convert foreign denominated securities or obligations
to U.S. dollar denominated investments.  Further, the International Equity Fund
may engage currency transactions to hedge the value of portfolio holdings
denominated in particular currencies against fluctuations in relative value.

Currency transactions include forward currency contracts, exchange listed
currency futures, exchange listed and OTC options on currencies, and currency
swaps. A forward currency contract involves a privately negotiated obligation to
purchase or sell (with delivery generally required) a specific currency at a
future date, which may be any fixed number of days from the date of the contract
agreed upon by the parties, at a price set at the time of the contract. A
currency swap is an agreement to exchange cash flows based on the notional
difference among two or more currencies and operates similarly to an interest
rate swap, which is described below. A Fund may enter into currency transactions
with counterparties which have received (or the guarantors of the obligations of
which have received) a credit rating of A-1 or P-1 by Standard and Poor's
Ratings Group ("S & P") or Moody's, Investors Service ("Moody's"), respectively,
or that have an equivalent rating from a nationally recognized statistical
rating organization ("NRSRO") or (except for OTC currency options) are
determined to be of equivalent credit quality by the adviser.

The International Equity Fund's dealings in forward currency contracts and other
currency transactions such as futures, options, options on futures, and swaps
will be limited to hedging involving either specific transactions or portfolio
positions.  Transaction hedging is entering into a currency transaction with
respect to specific assets or liabilities of a Fund, which will generally arise
in connection with the purchase or sale of its portfolio securities or the
receipt of income therefrom.  Position hedging is entering into a currency
transaction with respect to portfolio security positions denominated or
generally quoted in that currency.  For example, if the Fund believes that a
foreign currency may suffer a substantial decline against the U.S. dollar, it
may enter into a forward sale contract to sell an amount of that foreign
currency approximating the value of some or all of the Fund's portfolio
securities denominated in such foreign currency.  The Funds may also cross-hedge
currencies by entering into transactions to purchase or sell one or more
currencies that are expected to decline in value relative to other currencies to
which the Fund has or in which the Fund expects to have portfolio exposure.

A Fund will not enter into a transaction to hedge currency exposure to an extent
greater, after netting all transactions intended wholly or partially to offset
other transactions, than the aggregate market value (at the time of entering
into the transaction) of the securities held in its portfolio that are
denominated or generally quoted in or currently convertible into such currency,
other than with respect to proxy hedging as described below.

To reduce the effect of currency fluctuations on the value of existing or
anticipated holdings of portfolio securities, the Funds may also engage in proxy
hedging.  Proxy hedging is often used when the currency to which the Fund's
portfolio is exposed is difficult to hedge or to hedge against the dollar.
Proxy hedging entails entering into a forward contract to sell a currency whose
changes in value are generally considered to be linked to a currency or
currencies in which some or all of the Fund's portfolio securities are or are
expected to be denominated, and to buy U.S. dollars.  The amount of the contract
would not exceed the value of the Fund's securities denominated in linked
currencies.  For example, if the adviser considers that the Austrian schilling
is linked to the German deutsche mark (the "D-mark"), the Fund holds securities
denominated in schillings and the adviser believes that the value of schillings
will decline against the U.S. dollar, the adviser may enter into a contract to
sell D-marks and buy dollars.  Currency hedging involves some of the same risks
and considerations as other transactions with similar instruments.  Currency
transactions can result in losses to the Fund if the currency being hedged
fluctuates in value to a degree or in a direction that is not anticipated.
Further, there is the risk that the perceived linkage between various currencies
may not be present during the particular time that the Fund is engaging in proxy
hedging.

(3) RISKS REGARDING HEDGING INSTRUMENTS AND DERIVATIVES

Some of the general risks associated with hedging and the use of derivatives
include: (a) the possible absence of a liquid secondary market for any
particular hedging instrument at any time; (b) these instruments can be highly
volatile; and (c) the possible need to defer closing out certain positions to
avoid adverse tax consequences.  More specific risks are set forth below.

                                      B-6
<PAGE>
 
     (A) FORWARD CONTRACTS: Forward contracts involve a risk of 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 in value of the
     Funds' other assets.

     (B) CURRENCY TRANSACTIONS: Currency transactions are subject to risks
     different from those of other portfolio transactions.  Because currency
     control is of great importance to the issuing governments and influences
     economic planning and policy, purchases and sales of currency and related
     instruments can be negatively affected by government exchange controls,
     blockages, and manipulations or exchange restrictions imposed by
     governments.  These can result in losses to a Fund if it is unable to
     deliver or receive currency or funds in settlement of obligations and could
     also cause hedges it has entered into to be rendered useless, resulting in
     full currency exposure as well as incurring transaction costs.  Buyers and
     sellers of currency futures are subject to the same risks that apply to the
     use of futures generally.  Further, settlement of a currency futures
     contract for the purchase of most currencies must occur at a bank based in
     the issuing nation.  Trading options on currency futures is relatively new,
     and the ability to establish and close out positions on such options is
     subject to the maintenance of a liquid market which may not always be
     available.  Currency exchange rates may fluctuate based on factors
     extrinsic to that country's economy.

RESTRICTED AND ILLIQUID SECURITIES

None of the Funds currently expect to invest in restricted or illiquid
securities, although, as a non-fundamental policy, each Fund may invest no more
than 15% of its net assets in illiquid securities.  However, this policy does
not limit the purchases of securities eligible for resale to qualified
institutional buyers pursuant to Rule 144A under the Securities Act of 1933,
provided that such securities are determined to be liquid by the Board of
Trustees, or the adviser if such determination is pursuant to Board-approved
guidelines.  Such guidelines shall 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, resulting in
undesirable delays in selling these securities at prices representing fair
value.

FOREIGN SECURITIES

The International Equity Fund and to a lesser extent each of the other Funds are
permitted to invest in foreign securities.  With the exception of the
International Equity Fund, each Fund intends to invest in foreign securities
only if:  (i) such securities are U.S. denominated; or (ii) if such securities
are not U.S. denominated, the Fund contemporaneously enters into a foreign
currency transaction to hedge the currency risk associated with the particular
foreign security.  If a Fund's securities are held abroad, the countries in
which such securities may be held and the sub-custodian holding them must be
approved by the Board of Trustees under applicable SEC rules.  In buying foreign
securities, a Fund may convert U.S. dollars into foreign currency, but only to
effect securities transactions on foreign securities exchanges and not to hold
such currency as an investment.

Investments in foreign securities involve special risks and considerations.  As
foreign companies are not generally subject to uniform accounting, auditing and
financial reporting standards, practices and requirements comparable to those
applicable to domestic companies, there may be less publicly available
information about a foreign company than about a domestic company.  For example,
foreign markets have different clearance and settlement procedures.  Delays in
settlement could result in temporary periods when assets of a Fund are
uninvested.  The inability of a Fund to make intended security purchases due to
settlement problems could cause it to miss certain investment opportunities.
They may also entail certain other risks, such as the possibility of one or more
of the following:  imposition of dividend or interest withholding or
confiscatory taxes, higher brokerage costs, thinner trading markets, currency
blockages or transfer restrictions, expropriation, nationalization, military
coups or other adverse political or economic developments; less government
supervision and regulation of securities exchanges, brokers and listed
companies; and the difficulty of enforcing obligations in other countries.
Purchases of foreign securities are usually made in foreign currencies and, as a
result, a Fund may incur currency conversion costs and may be affected favorably
or unfavorably by changes in the value of foreign currencies against the U.S.
dollar.  Further, it may be more difficult for a Fund's agents to keep currently
informed about corporate actions which may affect the prices of portfolio
securities.  Communications between the United States and foreign countries may
be less reliable than within the United States, thus increasing the risk of
delayed settlements of portfolio transactions or loss of certificates for
portfolio securities.  Certain markets may require payment for securities before
delivery.  A Fund's 

                                      B-7
<PAGE>
 
ability and decisions to purchase and sell portfolio securities may be affected
by laws or regulations relating to the convertibility of currencies and
repatriation of assets.

A number of current significant political, demographic and economic developments
may affect investments in foreign securities and in securities of companies with
operations overseas.  Such developments include dramatic political changes in
government and economic policies in several Eastern European countries and the
republics composing the former Soviet Union, as well as the unification of the
European Economic Community.  The course of any one or more of these events and
the effect on trade barriers, competition and markets for consumer goods and
services are uncertain.  Similar considerations are of concern with respect to
developing countries.  For example, the possibility of revolution and the
dependence on foreign economic assistance may be greater in these countries than
in developed countries.  Management seeks to mitigate the risks associated with
these considerations through diversification and active professional management.

SHORT SALES AGAINST-THE-BOX

Selling short "against-the-box" refers to the sale of securities actually owned
by the seller but held in safekeeping.  In such short sales, while the short
position is open, a Fund must own an equal amount of such securities, or by
virtue of ownership of securities have the right, without payment of further
consideration, to obtain an equal amount of securities sold short.  Short sales
against-the-box may be made to defer, for federal income tax purposes,
recognition of gain or loss on the sale of securities "in the box" until the
short position is closed out.  None of the Funds currently intend to engage in
short sales against-the-box.

INVESTMENT BASKET

Notwithstanding any Fund's fundamental investment restrictions (except those
imposed as a matter of law), the Board of Trustees may authorize one or more of
the Funds to invest in any security or investment-related instrument, or to
engage in investment-related transactions or practices, such as newly developed
debt securities or hedging programs, provided that the Board of Trustees has
determined that to do so is consistent with the Fund's investment objectives and
policies and has adopted reasonable guidelines for use by the Fund's advisers,
and provided further that at the time of making such investment or entering into
such transaction, such investments or instruments account for not more than 10%
of the Fund's total assets.  The Trust has no current intention of using this
investment basket authority.

                      FUNDAMENTAL INVESTMENT RESTRICTIONS
                      -----------------------------------

Each Fund is subject to certain fundamental restrictions on its investments,
which may not be changed without the affirmative vote of a majority of the
outstanding shares of that Fund. Investment restrictions that appear below or
elsewhere in this Statement of Additional Information and in the Prospectus
which involve a maximum percentage of securities or assets shall not be
considered to be violated unless an excess over the percentage occurs
immediately after, and is caused by, an acquisition or encumbrance of securities
or assets of, or borrowings by or on behalf of, a Fund.  The Trust may not, on
behalf of any Fund:

     (1) Purchase any security (other than U.S. Treasury securities or U.S.
     Government Securities) if as a result, with respect to 75% of the Fund's
     assets, more than 5% of the value of the total assets (determined at the
     time of investment) of a Fund would be invested in the securities of a
     single issuer.

     (2) Borrow money, except from banks for temporary or emergency purposes not
     in excess of one-third of the value of a Fund's assets, except that a Fund
     may enter into reverse repurchase agreements or roll transactions.  For
     purposes of calculating this limitation, entering into portfolio lending
     agreements shall not be deemed to constitute borrowing money.  A Fund would
     not make any additional investments while its borrowings exceeded 5% of its
     assets.

    
     (3) Issue senior securities (as defined in the 1940 Act) except for
     securities representing indebtedness not prevented by paragraph (2) 
     above.     

     (4) Make short sales, except for sales "against the box."

                                      B-8
<PAGE>
 
     (5) Act as an underwriter, except to the extent that, in connection with
     the disposition of portfolio securities, a Fund may be deemed an
     underwriter under applicable laws.

     (6) Invest in oil, gas or other mineral leases, rights, royalty contracts
     or exploration or development programs, real estate or real estate mortgage
     loans.  This restriction does not prevent a Fund from purchasing readily
     marketable securities secured or issued by companies investing or dealing
     in real estate and by companies that are not principally engaged in the
     business of buying and selling such leases, rights, contracts or programs.

     (7) Purchase physical commodities or commodity contracts (except futures
     contracts, including but not limited to contracts for the future delivery
     of securities and futures contracts based on securities indices).

     (8) Make loans other than by investing in obligations in which a Fund may
     invest consistent with its investment objective and policies and other than
     repurchase agreements and loans of portfolio securities.

     (9) Pledge, mortgage or hypothecate assets taken at market to an extent
     greater than 15% of the total assets of the Fund except in connection with
     permitted transactions in options, futures contracts and options on futures
     contracts, reverse repurchase agreements and securities lending.

     (10) Purchase any security (other than securities issued, guaranteed or
     sponsored by the U.S. Government or its agencies or instrumentalities) if,
     as a result, a Fund would hold more than 10% of the outstanding voting
     securities of an issuer.

     (11) Purchase or retain securities of any issuer if, to the knowledge of
     the Trust, more than 5% of such issuer's securities are beneficially owned
     by officers and trustees of the Trust or officers and directors of its
     adviser who individually beneficially own more than 1/2 of 1% of the
     securities of such issuer.

Notwithstanding any fundamental investment restriction set forth above or in the
Prospectus, each Fund may: (1) engage in hedging transactions, techniques, and
practices using forward contracts and similar instruments, to the extent and in
a manner permitted by law; and (2) invest in any security or investment-related
instrument, or engage in any investment-related transaction or practice,
provided that the Board of Trustees has determined that to do so is consistent
with the investment objective and policies of the Fund and has adopted
reasonable guidelines for use by the Fund's adviser, and provided further that
at the time of entering into such investment or transaction, such investments or
instruments account for no more than 10% of the Fund's total assets.  For the
foreseeable future, the Funds do not expect to engage in futures and options
transactions or interest rate swap agreements.

                    NON-FUNDAMENTAL INVESTMENT RESTRICTIONS
                    ---------------------------------------

In addition to the investment restrictions described above and those contained
in the Prospectus, the Trustees of the Trust have voluntarily adopted certain
policies and restrictions which are observed in the conduct of the affairs of
the Funds.  These represent intentions of the Trustees based upon current
circumstances.  They differ from fundamental investment policies in that the
following additional investment restrictions may be changed or amended by action
of the Trustees without requiring prior notice to or approval of shareholders.

In accordance with such policies and guidelines, each Fund may not:

     (1) Invest for the purpose of exercising control over, or management of,
     any company.

     (2) Invest in securities of other investment companies, except by purchase
     in the open market where no commission or profit to a sponsor or dealer
     results from such purchase other than the customary broker's commission,
     except when such purchase is part of a plan of merger, consolidation,
     reorganization or acquisition or except shares of money market funds
     advised by MassMutual or an affiliate thereof.  It is expected that a Fund
     would purchase shares of such money market funds only if arrangements are
     made to eliminate duplicate advisory and distribution fees.

The Audit Committee makes recommendations to the Trustees as to the engagement
or discharge of the Trust's independent auditors, supervises investigations into
matters relating to audit functions, reviews with the Trust's independent
auditors the results of the audit engagement, and considers the audit fees. The
Nominating Committee consists of Trustees who are not "interested persons" (as
defined in the 1940 Act) of the Trust or any adviser and considers making all
nominations for non-interested members of the Board of Trustees.  The selection
and nomination of management nominees for such vacancies is committed to the
discretion of the Nominating Committee. The Investment Pricing Committee
determines the fair value of securities for which market quotations are not
readily available.

The officers and Trustees of the Trust as a group own less than 1% of any series
of outstanding shares of the Trust.

The Trust's shareholders have the right, upon the declaration in writing or vote
of at least two-thirds of the votes represented by its outstanding shares, to
remove a Trustee.  The Trustees shall call a meeting of shareholders to vote on
the removal of a Trustee upon the written request of the record holders of
shares representing at least 10% of all of the votes represented by all
outstanding shares of the Trust.  In addition, whenever ten or more shareholders
of record who have been such for at least six months preceding the date of
application, and who hold in the aggregate either shares having a net asset
value of at least $25,000 or at least 1% of the Trust's outstanding shares,
whichever is less, shall apply to the Trustees in writing, stating that they
wish to communicate with other shareholders with a view to obtaining signatures
for a request for a meeting for the purpose of voting upon the question of
removal of any Trustee or Trustees and accompanied by the form of communication
and request which they wish to transmit, the Trustees shall within five business
days after receipt of such application either:  (1) afford to such applicants
access to a list of the names and addresses of all shareholders as recorded on
the books of the Trust; or (2) inform such applicants as to the approximate
number of shareholders of record, and the 

                                      B-14
<PAGE>
 
    
approximate cost of mailing to them the proposed communication and form of
request. If the Trustees elect to follow the latter course, the Trustees, upon
the written request of such applicants, accompanied by a tender of the material
to be mailed and of the reasonable expenses of mailing, shall, with reasonable
promptness, mail such material to all shareholders of record at their addresses
as recorded on the books of the Trust, unless within five business days after
such tender the Trustees shall mail to such applicants and file with the
Securities and Exchange Commission (the ``SEC"), together with a copy of the
material to be mailed, a written statement signed by at least a majority of the
Trustees to the effect that in their opinion either such material contains
untrue statements of fact or omits to state facts necessary to make the
statements contained therein not misleading, or would be in violation of
applicable law, and specifying the basis of such opinion.     

After opportunity for hearing regarding the objections specified in the written
statement so filed, the SEC may, and if demanded by the Trustees or by such
applicants shall, enter an order either sustaining one or more of such
objections, or refusing to sustain any of them.  If the SEC shall enter an order
refusing to sustain any such objections or if, after the entry of an order
sustaining one or more of such objections, the SEC shall find, after notice and
opportunity for hearing, that all objections so sustained have been met, and
shall enter an order so declaring, the Trustees shall mail copies of such
material to all shareholders with reasonable promptness after the entry of such
order and the renewal of such tender.

On any matters submitted to a vote of shareholders, all shares of the Trust then
entitled to vote shall be voted  in the aggregate as a single class without
regard to Fund or class, except that:  (i) when required by the 1940 Act or when
the Trustees shall have determined that the matter affects one or more of the
Funds or classes materially differently, shares will be voted by individual Fund
or class; and (ii) when the Trustees have determined that any matter affects
only the interests of one or more Funds or classes, then only shareholders of
such Fund or class shall be entitled to vote thereon.  Shareholder inquiries
should be directed to MassMutual Institutional Funds, 1295 State Street,
Springfield, MA  01111.

              CONTROL PERSON AND PRINCIPAL HOLDERS OF SECURITIES
              --------------------------------------------------

    
MassMutual is a control person in that it owns, through certain of its separate

                      INVESTMENT MANAGER AND SUB-ADVISERS
                      -----------------------------------

INVESTMENT MANAGER

MassMutual serves as investment manager to each Fund pursuant to an Investment
Management Agreement with the Trust on behalf of each Fund dated September 30,
1994 (each an "Advisory Agreement").  Under each Advisory Agreement, MassMutual
is obligated to provide for the management of each Fund's portfolio of
securities and makes investment decisions with respect to the purchase and sale
of investments for the Prime Fund, the Short-Term Bond Fund, the Core Bond Fund
and the Prime and Core Bond Sectors of the Balanced Fund, subject to policies
established by the Trustees of the Trust and in accordance with each Fund's
investment objective, policies and restrictions as set forth herein and in the
Prospectus.

Each Advisory Agreement may be terminated at any time without the payment of any
penalty by the Trustees, or by vote of a majority of the outstanding shares of
the Fund, or by MassMutual, on sixty days' written notice.  In addition, each
Advisory Agreement automatically terminates if it is assigned or if its
continuance is not specifically approved at least annually (1) by the
affirmative vote of a majority of the Trustees or by the affirmative vote of a
majority of the Fund's shares, and (2) by an affirmative vote of a majority of
the Trustees who are not "interested persons" (as defined in the1940 Act) of the
Trust.  Under the terms of each Advisory Agreement, a Fund recognizes
MassMutual's control of the name "MassMutual" and the Trust agrees that its
right to use such name is non-exclusive and can be terminated by MassMutual at
any time.  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 also serves as investment adviser to: MassMutual Corporate Investors
and MassMutual Participation Investors, closed-end management investment
companies; MML Money Market Fund, MML Equity Fund, MML Managed Bond Fund, MML
Blend Fund and MML Equity Index Fund, which are series of MML Series Investment
Fund, an open-end management investment company; certain wholly owned
subsidiaries of MassMutual; MassMutual/Carlson CBO N.V., a corporation that
issued Collateralized Bond Obligations on or about May 1, 1991; MassMutual
Corporate Value Partners, a partnership formed in 1994 to provide investment
opportunities on a leverage basis in the public or

                                      B-15
<PAGE>
 
    
private high yield markets; MassMutual High Yield Partners LLC, a limited
liability company formed in 1996 to invest in publicly traded high yield bonds,
high yield syndicated bank debt and public convertible securities and various
employee benefit plans.    

The Trust, on behalf of each Fund, pays MassMutual an investment advisory fee
monthly, at an annual rate based upon the average daily net assets of that Fund
as follows:  .45% for the Prime Fund, the Short-Term Bond Fund, the Core Bond
Fund, the Balanced Fund and the Value Equity Fund;  .55% for the Small Cap Value
Equity Fund;  and .85% for the International Equity Fund.

    
For the last three fiscal periods, the Funds have paid the following amounts as
investment advisory fees to MassMutual pursuant to each Advisory Agreement:

INVESTMENT SUB-ADVISERS

    
Securities held by the Funds are also frequently held by MassMutual investment
accounts and by other investment companies and accounts for which MassMutual or
Babson act as investment adviser or sub-adviser.  If the same security is
purchased or sold for any Fund and such accounts or companies at or about 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 and 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,     

                                      B-17
<PAGE>
 
    
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 the Trust's management that such execution advantage and
the desirability of retaining MassMutual and Babson as advisers of the Funds
outweigh the disadvantages, if any, which might result from this procedure.     

    
Babson is a wholly-owned subsidiary of DLB Acquisition Corporation, an indirect,
controlled subsidiary of MassMutual.  HarbourView is a wholly owned subsidiary
of OppenheimerFunds, Inc. which is a wholly owned subsidiary of Oppenheimer
Acquisition Corporation ("OAC"), a holding company owned in part by senior
management of OAC and ultimately controlled by MassMutual.  MassMutual, Babson
and HarbourView are each registered with the SEC as investment advisers.     

                                THE DISTRIBUTOR
                                ---------------

The Trust's shares are continuously distributed by Oppenheimer Funds
Distributor, Inc. (the "Distributor") pursuant to a Distribution Agreement with
the Trust dated August 5, 1994.  The Distributor pays commissions to its selling
dealers as well as the cost of printing and mailing Prospectuses to potential
investors and of any advertising incurred by it in connection with distribution
of shares of the Funds.

    
Pursuant to Rule 12b-1 under the 1940 Act, the plans of distribution ("Plans")
described in the Prospectus were approved on August 5, 1994 by the shareholders
of each of the Funds.  The Trustees of the Trust, including a majority of the
Trustees who are not interested persons of the Trust and who have no direct or
indirect financial interest in the operation of the Plans, by vote cast in
person at a meeting called for the purpose of voting on such Plan, approved the
Plans of the Funds on August 5, 1994.  Pursuant to the Plans, the Distributor
shall provide the Trustees, at least quarterly, a written report of the amounts
expended under each Plan and the purpose for which such expenditures were made.
Permissible purposes for payments of fees pursuant to the Plans may include:
brokerage commissions; sales bonuses; and expenses related to marketing,
printing and distribution of the Funds' prospectus, answering shareholder
inquiries and preparing shareholder reports.     

Each Plan will remain in effect for more than one year, provided such
continuance is approved annually by a vote of the Trustees in the manner
described above.  No Plan may be amended to increase materially the amount to be
spent for the services described therein without approval of the shareholders of
the class to which it applies, and all material amendments of each Plan must be
approved by the Trustees in the manner described above.  Each Plan may be
terminated at any time, without payment of any penalty, by vote of a majority of
the Trustees who are not interested persons of the Trust and who have no direct
or indirect financial interest in the operations of the Plan, or by a vote of a
majority of the outstanding voting securities of the class to which it applies
(as defined in the 1940 Act).  So long as any Plan is in effect, the selection
and nomination of Trustees who are not such interested persons have been
committed to those Trustees who are not interested persons.  The Trustees have
determined that, in their judgment, there is a reasonable likelihood that each
Plan will benefit the respective class and its shareholders.

In addition, MassMutual may reimburse the Distributor for distribution and/or
service expenses from any source available to it, including management and
administration fees paid to it by the Funds. MassMutual directly, or through the
Distributor, may, subject to the approval of the Board of Trustees, make
payments to securities dealers and other third parties who engage in the sale of
shares or who render shareholder support services, including but not limited to
providing office space, equipment and telephone facilities, answering routine
inquiries regarding the Funds, processing shareholder transactions and providing
such other shareholder services as the Funds may reasonably request. To the
extent that any payments made by the Funds to MassMutual, including payment of
management and administration fees, should be deemed to be indirect financing of
any activity primarily intended to result in the sale of the shares issued by
the Funds within the context of Rule 12b-1 under the 1940 Act, then such
payments shall be deemed to be authorized by the Funds' Plan.

    
            CUSTODIAN, DIVIDEND DISBURSING AGENT AND TRANSFER AGENT     
            -------------------------------------------------------

Investors Bank & Trust Company is the custodian of the Funds' investments (the
"Custodian") and is the Funds' transfer agent and dividend disbursing agent (the
"Transfer Agent").  The Custodian and the Transfer Agent do not assist in, and
are not responsible for, the investment decisions and policies of the Funds.

                      PORTFOLIO TRANSACTIONS AND BROKERAGE
                      ------------------------------------

Purchases and sales of securities on a securities exchange are effected by
brokers, and each Fund which purchases or sells securities on a securities
exchange pays a brokerage commission for this service.  In transactions on stock
exchanges in the United States, these commissions are negotiated, whereas on
many foreign stock exchanges these commissions are fixed.  In the over-the-
counter markets, securities are generally traded on a "net" basis with dealers
acting as principal for their own accounts without a stated commission, although
the price of the security usually includes a profit to the dealer.  In
underwritten offerings, securities are purchased at a fixed price which includes
an amount of compensation to the underwriter, generally referred to as the
underwriter's concession or discount.  On occasion, certain money market
instruments may be purchased directly from an issuer, in which case no
commissions or discounts are paid.

The primary consideration in placing portfolio security transactions with
broker-dealers for execution is to obtain and maintain the availability of
execution at the most favorable prices and in the most effective manner
possible.  Each adviser attempts to achieve this result by selecting broker-
dealers to execute portfolio transactions on the basis of their professional
capability, the value and quality of their brokerage services and the level of
their brokerage commissions.

Under each Advisory Agreement and as permitted by Section 28(e) of the
Securities Exchange Act of 1934, an adviser may cause a Fund to pay a broker-
dealer which provides brokerage and research services to the adviser an amount
of commission for effecting a securities transaction for a Fund in excess of the
amount other broker-dealers would have charged for the transaction if the
adviser determines in good faith that the greater commission is reasonable in
relation to the value of the brokerage and research services provided by the
executing broker-dealer viewed in terms of either a particular transaction or
the adviser's overall responsibilities to the Trust and to its other clients.
The term "brokerage and research services" includes:  advice as to the value of
securities, the advisability of investing in, purchasing, or selling securities,
and the availability of securities or of purchasers or sellers of securities;
furnishing analyses and reports concerning issuers, industries, securities,
economic factors and trends, portfolio strategy and the performance of accounts;
and effecting securities transactions and performing functions incidental
thereto such as clearance and settlement.

Although commissions paid on every transaction will, in the judgment of the
adviser, be reasonable in relation to the value of the brokerage services
provided, commissions exceeding those which another broker might charge may be
paid to broker-dealers (except the Distributor) who were selected to execute
transactions on behalf of the Trust and the adviser's other clients in part for
providing advice as to the availability of securities or of purchasers or
sellers of securities and services in effecting securities transactions and
performing functions incidental thereto such as clearance and settlement.

Broker-dealers may be willing to furnish statistical, research and other factual
information or services ("Research") to an adviser for no consideration other
than brokerage or underwriting commissions.  Securities may be bought or sold
through such broker-dealers, but at present, unless otherwise directed by the
Trust, a commission higher than one charged elsewhere will not be paid to such a
firm solely because it provided Research to the adviser.  Research provided by
brokers is used for the benefit of all of the adviser's clients and not solely
or necessarily for the benefit of the Trust.  The adviser attempts to evaluate
the quality of Research provided by brokers.  Results of this effort are
sometimes used by the adviser as a consideration in the selection of brokers to
execute portfolio transactions.

The investment advisory fee that the Trust pays on behalf of each Fund to
MassMutual will not be reduced as a consequence of an adviser's receipt of
brokerage and research services.  To the extent the Trust's portfolio
transactions are used to obtain such services, the brokerage commissions paid by
the Trust will exceed those that might otherwise be paid, by an amount which
cannot now be determined.  Such services would be useful and of value to an
adviser in serving both the Trust and other clients and, conversely, such
services obtained by the placement of brokerage business of other clients would
be useful to an adviser in carrying out its obligations to the Trust.

    
Brokerage commissions paid by the Funds for the fiscal years ended December 31,
1996 and December 31, 1995 and for the period ended December 31, 1994,
respectively, were as follows:   Balanced Fund $115,756, $87,156 and     

                                      B-19

$20,315; Value Equity Fund $933,716, $643,882 and $128,536; Small Cap Value
Equity Fund $430,964, $291,912 and $50,261; and International Equity Fund
$1,103,103, $1,218,802 and $55,656.     

    
The Prime Fund, Short-Term Bond Fund and the Core Bond Fund did not incur
brokerage commissions during these periods.     

                         SHAREHOLDER INVESTMENT ACCOUNT
                         ------------------------------

A Shareholder Investment Account is established for each Investor in the
Funds./1/  Each account contains a record of the shares of each Fund maintained
by the Transfer Agent.  No share certificate will be issued.  Whenever a
transaction takes place in the Shareholder Investment Account, the Investor will
be mailed a statement showing the transaction and the status of the account.

                              REDEMPTION OF SHARES
                              --------------------

With respect to each Fund, the Trustees may suspend the right of redemption,
postpone the date of payment or suspend the determination of net asset value (a)
for any period during which the New York Stock Exchange ("NYSE") is closed
(other than for customary weekend and holiday closing), (b) for any period
during which trading in the markets the Fund normally uses is restricted, (c)
when an emergency exists as determined by the SEC so that disposal of the Fund's
investments or a determination of its net asset value is not reasonably
practicable, or (d) for such other periods as the SEC by order may permit for
the protection of the Trust's shareholders.  While the Trust's Declaration of
Trust would permit it to redeem shares in cash or other assets of the Fund or
both, it has filed an irrevocable election with the SEC to pay in cash all
requests for redemption received from any shareholder if the aggregate amount of
such requests in any 90-day period does not exceed the lesser of $250,000 or 1%
of a Fund's net assets.

                       VALUATION OF PORTFOLIO SECURITIES
                       ---------------------------------

The net asset value per share of each Fund is determined by the Transfer Agent
as of the close of the NYSE, currently 4:00 p.m., Eastern Time, on each day the
NYSE is open for trading and the Custodian is open for business.

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, or in the case of over-the-counter securities not
so listed, the last reported bid price.  Debt securities (other than short-term
obligations with a remaining maturity of sixty days or less) 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.  Money market obligations with a remaining maturity of sixty days
or less are valued at amortized cost unless such value does not represent fair
value.  All other securities and other assets, including debt securities the
prices for which supplied by a pricing agent are deemed by MassMutual not to be
representative of market values, but excluding money market instruments with a
remaining maturity of sixty days or less and including restricted securities and
securities for which no market quotation is available, are valued at fair value
in accordance with procedures approved by and determined in good faith by the
Trustees, although the actual calculation may be done by others.

Portfolio securities traded on more than one U.S. national securities exchange
or foreign securities exchange are valued at the last price on the business day
as of which such value is being determined at the close of the exchange
representing the principal market for such securities.  All assets and
liabilities expressed in foreign currencies will be converted into U.S. dollars
at the mean between the buying and selling rates of such currencies against U.S.
dollars last quoted by any major bank.  If such quotations are not available,
the rate of exchange will be determined in accordance with policies established
by the Trustees.

The proceeds received by each Fund for each issue or sale of its shares, and all
net investment income, realized and unrealized gain will be specifically
allocated to such Fund and constitute the underlying assets of that Fund.  The

___________________

/1/ "Investor" includes a plan sponsor, plan fiduciary, trust, institutional
investor, and/or insurance company separate investment account that purchases
shares of the Trust.  An Investor that is a separate investment account of
MassMutual is referred to as a "SIA Investor."  Investors that are purchasing
shares of a fund on behalf of a Plan are sometimes referred to as "Plan
Investors."  The term Investor does not include a Plan Participant.

underlying assets of each Fund will be segregated on the books of account, and
will be charged with the liabilities in respect of such Fund and with a share of
the general liabilities of the Trust.  Expenses with respect to any two or more
Funds are to be allocated in proportion to the net asset values of the
respective Funds except where allocations of direct expenses can otherwise be
fairly made.  Each class of shares of a Fund will be charged with liabilities
directly attributable to such class, and other Fund expenses are to be allocated
in proportion to the net asset values of the respective classes.

                             DESCRIPTION OF SHARES
                             ---------------------

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

                             INVESTMENT PERFORMANCE
                             ----------------------

The yield of the Prime Fund, the Short-Term Bond Fund and the Core Bond Fund, as
well as total return figures for all of the Funds, may be provided in reports,
sales literature and advertisements.  Any performance information with respect
to Class 4 shares will be provided net of SIA and Fund expenses.

Yield for each class of shares of such Funds will be based upon a stated 30-day
period and 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 + 1)/6/ - 1]
                    ----- 
                     cd

     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 also advertise its total return for each class of shares.
Total return quotations will be based upon a stated period and will be computed
by determining 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 $1000.
               T =  average annual total return.
               n =  number of years.
             ERV =  ending redeemable value at the end of the stated period of a
                    hypothetical $1000 payment made at the beginning of the
                    stated period.

    
The Funds may show total return calculated without giving effect to the expense
reduction in management fee by MassMutual under "Expense Information" in the
Prospectus  ("Standardized Total Return Without Reduction in Management Fee").
Each investment performance figure will be carried to the nearest hundredth of
one percent.  The expense reduction in management fees has been eliminated
effective May 1, 1997.  See "Expense Information" in the Prospectus.     

                                      B-21
<PAGE>
 
A Fund's yield or total return is not fixed or guaranteed and the Fund's
principal is not insured.  Investment performance quotations should not be
considered to be representations of the performance for any period in the
future.  The yield is a function of available interest rates on securities in
which the Fund invests, which can be expected to fluctuate, as well as of the
quality, maturity and types of portfolio instruments held by the Fund and of the
Fund's operating expenses.  The yield may be affected if, through net sales of
its shares, there is a net investment of new money in the Fund which the Fund
invests at returns different from those being earned on current portfolio
instruments.  Yield may also vary if the Fund experiences net redemptions, which
may require the disposition of some of the Fund's current portfolio instruments.
Total return is a function of the value of the Fund's portfolio securities over
time, which may be expected to fluctuate, as well as of income earned by the
Fund on such securities and of the Fund's operating expenses.

    
Set forth below is the average annual total return information for Class 3
shares of the Prime Fund, Short-Term Bond Fund, Core Bond Fund, Balanced Fund,
Value Equity Fund, Small Cap Value Equity Fund and International Equity Fund for
the one-year and since inception* periods ended December 31, 1996.  Also set

                                    TAXATION
                                    --------

Each Fund intends to qualify each year and elect to be taxed as a regulated
investment company under Subchapter M of the Internal Revenue Code of 1986, as
amended (the "Code").  In order to qualify as a "regulated investment company,"
a Fund must, among other things:  (a) derive at least 90% of its gross income
from dividends, interest, payments with respect to securities loans, gains from
the sale or other disposition of stock, securities, or foreign currencies, and
other income (including gains from forward contracts) derived with respect to
its business of investing in such stock, securities, or currencies; (b) derive
less than 30% of its gross income from the sale or other disposition of certain
assets (including stock and securities) held less than three months; (c)
diversify its holdings so that, at the close of each quarter of its taxable
year, (i) at least 50% of the value of its total assets consists of cash, 

                                      B-22
<PAGE>
 
cash items, U.S. Government securities, and other securities limited generally
with respect to any one issuer to not more than 5% of the total assets of the
Fund and not more than 10% of the outstanding voting securities of such issuer,
and (ii) not more than 25% of the value of its assets is invested in the
securities of any issuer (other than U.S. Government securities). If a Fund
fails to qualify as a regulated investment company, it will be treated as an
ordinary corporation for federal income tax purposes.

As a regulated investment company electing to have its tax liability determined
under Subchapter M, in general a Fund will not be subject to federal income tax
on its ordinary income or capital gains that are distributed.  As a
Massachusetts business trust, a Fund under present law will not be subject to
any excise or income taxes imposed by Massachusetts.

An excise tax at the rate of 4% will be imposed on the excess, if any, of each
Fund's "required distribution" over its actual distributions in any calendar
year.  Generally, the "required distribution" is 98% of the Fund's ordinary
income for the calendar year plus 98% of its capital gain net income recognized
during the one-year period ending on October 31 (or December 31, if the Fund so
elects) plus undistributed amounts from prior years.  Each Fund intends to make
distributions sufficient to avoid imposition of the excise tax.  Distributions
declared by a Fund during October, November or December to shareholders of
record on a date in any such month and paid by the Fund during the following
January will be treated for federal tax purposes as paid by the Fund and
received by shareholders on December 31 of the year in which declared.

Except in the case of certain shareholders eligible for preferential tax
treatment, e.g., qualified retirement or pension trusts, shareholders of each
Fund will be subject to federal income taxes on distributions made by the Fund
whether received in cash or additional shares of the Fund.  Distributions by
each Fund of net income and short-term capital gains, if any, will be taxable to
shareholders as ordinary income.  Designated distributions of long-term capital
gains, if any, will be taxable to shareholders as long-term capital gains,
without regard to how long a shareholder has held shares of the Fund.  A loss on
the sale of shares held for six months or less will be treated as a long-term
capital loss to the extent of any long-term capital gain dividend paid to the
shareholder with respect to such shares.

Dividends and distributions on Fund shares received shortly after their
purchase, although in effect a return of capital, are subject to federal income
taxes.  Investment income and gains received by a Fund from sources outside the
United States might be subject to foreign taxes which are withheld at the
source.  The effective rate of these foreign taxes cannot be determined in
advance because it depends on the specific countries in which its assets will be
invested, the amount of the assets invested in each such country and the
possible applicability of treaty relief.

The International Equity Fund may be eligible to make an election under Section
853 of the Code so that any of its shareholders subject to federal income taxes
will be able to claim a credit or deduction on their income tax returns for, and
will be required to treat as part of the amounts distributed to them, their pro
rata portion of qualified taxes paid by the Fund to foreign countries.  The
ability of shareholders of the Fund to claim a foreign tax credit is subject to
certain limitations imposed by Section 904 of the Code, which in general limits
the amount of foreign tax that may be used to reduce a shareholder's U.S. tax
liability to that amount of U.S. tax which would be imposed on the amount and
type of income in respect of which the foreign tax was paid.  A shareholder who
for U.S. income tax purposes claims a foreign tax credit in respect of Fund
distributions may not claim a deduction for foreign taxes paid by the Fund,
regardless of whether the shareholder itemizes deductions.  Also, under Section
63 of the Code, no deduction for foreign taxes may be claimed by shareholders
who do not itemize deductions on their federal income tax returns.  It should
also be noted that a tax-exempt shareholder, like other shareholders, will be
required to treat as part of the amounts distributed to it a pro rata portion of
the income taxes paid by the Fund to foreign countries.  However, that income
will generally be exempt from U.S. taxation by virtue of such shareholder's tax-
exempt status and such a shareholder will not be entitled to either a tax credit
or a deduction with respect to such income.  The International Equity Fund will
notify shareholders each year of the amount of dividends and distributions and
the shareholder's pro rata share of qualified taxes paid by the Fund to foreign
countries.  Each Fund may limit its investments in certain "passive foreign
investment companies" in order to avoid certain taxes that arise as a result of
such investments.

Redemptions and exchanges of each Fund's shares are taxable events and,
accordingly, shareholders subject to federal income taxes may realize gains and
losses on these transactions.  If shares have been held for more than one year,
gain or loss realized will be long-term capital gain or loss, provided the
shareholder holds the shares as a 

                                      B-23
<PAGE>
 
capital asset. Furthermore, no loss will be allowed on the sale of Fund shares
to the extent the shareholder acquired other shares of the same Fund within 30
days prior to the sale of the loss shares or 30 days after such sale. The state
and local tax effects of distributions received from a Fund, and any special tax
considerations associated with foreign investments of the Fund, should be
examined by investors with regard to their own tax situation.

A Fund's ability to use forward contracts and other hedging techniques, and to
engage in certain other transactions, may be limited by tax considerations.  In
order to ensure that it derives less than 30% of its gross income from
securities and certain other investment assets held less than three months, a
Fund will be restricted in selling securities held or considered to have been
held less than three months, and in engaging in hedging or other activities
which may cause the Fund's holding period in certain of its assets to be less
than three months.  These rules could also affect the amount, timing and
character of distributions.

A Fund's transactions in foreign currency-denominated debt instruments and its
hedging activities will likely produce a difference between its book income and
its taxable income. This difference may cause a portion of the Fund's
distributions of book income to constitute returns of capital for tax purposes
or require the Fund to make distributions exceeding book income in order to
permit the Fund to continue to qualify, and be taxed under Subchapter M of the
Code, as a regulated investment company.

Under federal income tax law, a portion of the difference between the purchase
price of zero-coupon securities in which a Fund has invested and their face
value ("original issue discount") is considered to be income to the Fund each
year even though the Fund will not receive cash interest payments from these
securities.  This original issue discount (imputed income) will make up a part
of the net investment income of the Fund which must be distributed to
shareholders in order to maintain the qualification of the Fund as a regulated
investment company and to avoid federal income tax at the level of the Fund.
Moreover, under regulations to be issued, a Fund may be limited in its ability
to borrow money, including through the use of reverse repurchase agreements.

The foregoing is a general and abbreviated summary of the applicable provisions
of the Code and regulations currently in effect.  For the complete provisions,
reference should be made to the pertinent Code sections and regulations.  The
Code and regulations are subject to change by legislative or administrative
action.  This discussion of the federal income tax treatment of the Fund and its
shareholders does not describe in any respect the tax treatment of any
particular arrangement, e.g., tax-exempt trusts or insurance products, pursuant
to which or by which investments in the Fund may be made.

                  APPENDIX - DESCRIPTION OF SECURITIES RATINGS

    
Although the ratings of fixed-income securities by Standard & Poor's Ratings
Group ("S&P") and Moody's Investors Service, Inc. ("Moody's") are a
generally accepted measurement of credit risk, they are subject to certain
limitations.  For example, ratings are based primarily upon historical events
and do not necessarily reflect the future.  Furthermore, there is a period of
time between the issuance of a rating and the update of the rating, during which
time a published rating may be inaccurate.     

The descriptions of the S&P and Moody's commercial paper, bond and municipal
securities ratings are set forth below.

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.  The A, A-1 and A-w
categories are described as follows:

 A   Issues assigned this highest rating are regarded as having the greatest
 capacity for timely payment.  Issues in this category are further refined with
 the designations 1, 2, and 3 to indicate the relative degree of safety.
 A-1  This designation indicates that the degree of safety regarding timely
 payment is either overwhelming or very strong.  Those issues determined to
 possess overwhelming safety characteristics will be noted with a plus (+) sign
 designation.
 A-2  Capacity for timely payment on issues with this designation is strong.
 However, the relative degree of safety is not as high as for issues designated
 A-1.

Moody's 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:

 Issuers (or supporting institutions) rated Prime-1 (or P-1) have a superior
 ability for repayment of senior short-term debt obligations.  Prime-1 (or P-1)
 repayment ability will normally 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.

 Issuers (or supporting institutions) rated Prime-2 (or P-2) have a strong
 ability for repayment of senior short-term debt 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.

BOND RATINGS:

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

 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 a 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.
 BBB  Debt rated BBB is regarded as having an adequate capacity to pay interest
 and repay principal.  Whereas such debt 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.

                                      B-25
<PAGE>
 
 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 compose 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 in Aaa securities.
 A  Bonds which are rated A possess many favorable investment attributes and may
 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 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 indicates that the issue ranks in the lower end of its generic rating
 category.

REPORT OF INDEPENDENT ACCOUNTANTS

To the Board of Trustees and Shareholders of the
MassMutual Institutional Funds:

We have audited the accompanying statements of assets and liabilities of the
MassMutual Institutional Funds, comprising, respectively, the Prime, Short-Term
Bond, Core Bond, Balanced, Value Equity, Small Cap Value Equity and
International Equity Funds, (the ``Funds"), including the portfolios of
investments, as of December 31, 1996, 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
two years in the period then ended and for the period from October 3, 1994
(commencement of operations) through December 31, 1994. These financial
statements and financial highlights are the responsibility of the Funds'
management. Our responsibility is to express an opinion on these financial
statements and financial highlights 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, 1996, 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 respective Funds constituting the MassMutual Institutional Funds as of
December 31, 1996 and the results of their operations for the year then ended,
the changes in their net assets for each of the two years in the period then
ended, and their financial highlights for each of the two years in the period
then ended and for the period from October 3, 1994 (commencement of operations)
through December 31, 1994, in conformity with generally accepted accounting
principles.

    commissions paid during the fiscal year by the total number of shares
    purchased and sold during the fiscal year for which commissions were
    charged. For fiscal years beginning on or after September 1, 1995, a Fund is
    required to disclose its average commission rate per share for security
    trades on which commissions are charged.

          Investment Company Act of 1940, as amended (the "1940 Act"), as an
          open-end, diversified management investment company. The Trust is
          organized under the laws of the Commonwealth of Massachusetts as a
          Massachusetts business trust pursuant to an Agreement and Declaration
          of Trust dated May 28, 1993, as amended. The Trust consists of seven

          defined contribution plans that satisfy the qualification requirements
          of Section 401(a) of the Internal Revenue Code of 1986, as amended
          (the "Code"). Class 4 shares of each Fund are available only to
          separate investment accounts ("SIAs") of Massachusetts Mutual Life
          Insurance Company ("MassMutual") in which corporate qualified plans

          all of which commenced operations on October 3, 1994.

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. The preparation of the financial statements in accordance
          with generally accepted accounting principles requires management to
          make estimates and assumptions that affect the reported amounts and
          disclosures in the financial statements. Actual results could differ
          from those estimates.

     Investment Valuation

          Equity securities are valued on the basis of valuations furnished by a
          pricing service, authorized by the Board of Trustees ("Trustees"),
          which provides the last reported sale price for securities listed on a
          national securities exchange or on the NASDAQ national market system,
          or in the case of over-the-counter securities not so listed, the last
          reported bid price. Debt securities (other than short-term obligations
          with a remaining maturity of sixty days or less) are valued on the
          basis of valuations furnished by a pricing service, authorized by the
          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. Money market
          obligations with a remaining maturity of sixty days or less are valued
          at either amortized cost or at original cost plus accrued interest,
          whichever approximates current market value. All other securities and
          other assets, including debt securities for which the prices supplied
          by a pricing agent are deemed by MassMutual not to be representative
          of market values, and including restricted securities and securities
          for which no market quotation is available, are valued at fair value
          in accordance with procedures approved by and determined in good faith
          by the Trustees, although the actual calculation may be done by
          others.

          Portfolio securities traded on more than one national securities
          exchange are valued at the last price on the business day as of which
          such value is being determined at the close of the exchange
          representing the principal market for such securities. All assets and
          liabilities expressed in foreign currencies will be converted into
          U.S. dollars at the mean between the buying and selling rates of such
          currencies against U.S. dollars last quoted by any major bank. If such
          quotations are not available, the rate of exchange will be determined
          in accordance with policies established by the Trustees.

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

     Accounting for Investments

          Investment transactions are accounted for on the trade date. Realized
          gains and losses on sales of investments and unrealized appreciation
          and depreciation of investments are computed on the specific
          identification cost method. Interest income, adjusted for amortization
          of discounts and premiums on investments, is earned from the
          settlement date and is recorded on the accrual basis. Dividend income
          is recorded on the ex-dividend date.

     Federal Income Tax

          It is each Fund's intent to continue to comply with the provisions of
          subchapter M of the Code applicable to a regulated investment company.
          Under such provisions, the Funds will not be subject to federal income
          taxes on their ordinary income and net realized capital gain to the
          extent they are distributed or deemed to have been distributed to
          their shareholders. Therefore, no Federal income tax provision is
          required.

     Dividends and Distributions to Shareholders

          Dividends from net investment income and distributions of any net
          realized capital gains of each Fund are declared and paid annually and
          at other times as may be required to satisfy tax or regulatory
          requirements. Distributions to shareholders are recorded on the ex-
          dividend date. Income and capital gain distributions are determined in
          accordance with income tax regulations which may differ from generally
          accepted accounting principles. These differences are primarily due to
          investments in forward contracts, passive foreign investment
          companies, 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.

     Foreign Currency Translation

          The books and records of the Funds are maintained in U.S. dollars. The
          market values of foreign currencies, foreign securities and other
          assets and liabilities denominated in foreign currencies are
          translated into U.S. dollars at the mean of the buying and selling
          rates of such currencies against the U.S. dollar at the end of each
          business day. Purchases and sales of foreign securities and income and
          expense items are translated at the rates of exchange prevailing on
          the respective dates of such transactions. The Funds do not isolate
          that portion of the results of operations arising from changes in the
          exchange rates from that portion arising from changes in the market
          prices of securities.

          Net realized foreign currency gains and losses resulting from changes
          in exchange rates include foreign currency gains and losses between
          trade date and settlement date on investment securities transactions,
          foreign currency transactions and the difference between the amounts
          of dividends recorded on the books of the Funds and the amount
          actually received.

     Forward Foreign Currency Contracts

          Each Fund may enter into forward foreign currency contracts in order
          to convert foreign denominated securities or obligations to U.S.
          dollar denominated investments. The International Equity Fund may
          engage in such transactions to manage the value of portfolio holdings
          against future movements in certain foreign currency exchange rates. A
          forward foreign currency contract is an agreement between two parties
          to buy and sell a currency at a set price on a future date. The market
          value of a forward currency contract fluctuates with changes in
          forward foreign currency exchange rates. Forward foreign currency
          contracts are marked to market daily and the change in their value is
          recorded by the Funds as an unrealized gain or loss. When a forward
          foreign currency contract is extinguished, through delivery or offset
          by entering into another forward foreign currency contract, the Funds
          record a realized gain or loss equal to the difference between the
          value of the contract at the time it was opened and the value of the
          contract at the time it was extinguished or offset.

          Forward foreign currency contracts involve a risk of loss from the
          potential inability of counterparties to meet the terms of their
          contracts and from unanticipated movements in foreign currency values
          and interest rates.

NOTES TO FINANCIAL STATEMENTS (CONTINUED)

          The notional or contractual amounts of these instruments represent the
          investments the Funds have in particular classes of financial
          instruments and do not necessarily represent the amounts potentially
          subject to risk. The measurement of the risk associated with these
          instruments is meaningful only when all related and offsetting
          transactions are considered. A summary of obligations for the

</TABLE>

     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. Delivery and
          payment for securities purchased on a forward commitment basis can
          take place a month or more after the date of the transaction. The
          Funds instruct the custodian to segregate 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 repurchase 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. When a forward commitment contract is closed, the
          Funds record a realized gain or loss equal to the difference between
          the value of the contract at the time it was opened and the value of
          the contract at the time it was extinguished. 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 cannot close out their forward commitments because of
          an illiquid secondary market, or the inability of counterparties to
          perform. The Funds monitor exposure to ensure counterparties are
          creditworthy and concentration of exposure is minimized. A summary of
          open obligations under these forward commitments at December 31, 1996,
          is as follows:

     Allocation of Operating Activity

          In maintaining the records for the Funds, the income and expense
          accounts are allocated to each class of shares. Investment income,
          unrealized and realized gains or losses are prorated among the classes
          of shares based on the relative net assets of each. Expenses are
          allocated to each class of shares depending on the nature of the
          expenditures. Administration and distribution and service fees, which
          are directly attributable to a class of shares, are charged to that
          class' operations. Expenses of the Fund not directly attributable to
          the operations of any class of shares or Fund are prorated among the
          Funds and classes to which the expense relates based on the relative
          net assets of each. Total expenses per class are currently limited to
          a percentage of average daily net assets, as discussed in Note 3.

     Investment Management Fees

          Under an agreement between the Trust and MassMutual, MassMutual is
          responsible for providing investment management of each Fund. In
          return for this service, MassMutual receives advisory fees monthly
          based upon each Fund's average daily net assets at the following
          annual rates:

          MassMutual has entered into investment sub-advisory agreements with
          two subsidiaries: David L. Babson & Company, Inc. ("Babson") and
          HarbourView Asset Management Corporation ("HarbourView"). These
          agreements provide that (1) effective January 1, 1997, Babson will
          manage the investment and reinvestment of the assets of the Value
          Equity Fund, the Small Cap Value Equity Fund and the Value Equity
          sector of the Balanced Fund, and (2) HarbourView will manage the
          investment and reinvestment of the assets of the International Equity
          Fund. Prior to January 1, 1997, Concert Capital Management ("Concert
          Capital") served as the investment sub-advisor to the Value Equity
          Fund, the Small Cap Value Equity Fund and the Value Equity sector of
          the Balanced Fund.  On January 1, 1996, the employees of Concert

          between each Fund and MassMutual, MassMutual provides certain
          administrative and shareholder services and bears some class specific
          administrative expenses. In return for these services, MassMutual

6. Foreign     The International Equity Fund invests substantially all of its
   Securities  assets in foreign securities. The other Funds may also invest in
               foreign securities, subject to certain percentage restrictions.
               Investing in securities of foreign companies and foreign
               governments involves special risks and considerations not
               typically associated with investing in securities of U.S.
               companies and the U.S. Government. These risks include
               revaluation of currencies and future adverse political and
               economic developments. Moreover, securities of many foreign
               companies and foreign governments and their markets may be less
               liquid and their prices more volatile than those of securities of
               comparable U.S. companies and the U.S. Government.

8. Line of     On January 11, 1996, the Trust, on behalf of each Fund, entered
   Credit      into a discretionary line of credit agreement with PNC Bank, N.A.
               Each Fund may borrow under the line of credit, provided that the
               Trust's borrowings do not exceed $50,000,000 in the aggregate at
               any one time. Interest is charged based on outstanding borrowings
               at the Federal Funds Rate plus .45%. Only the International

Item 25: Person Controlled by or Under Common Control with Registrant     

At the date of this Post-Effective Amendment to the Registration Statement,
Registrant did not, directly or indirectly, control any person.

Registrant was organized by MassMutual primarily to offer investors both the
opportunity to pursue long-term investment goals and the flexibility to respond
to changes in their investment objectives and economic and market conditions.
Initially, the Registrant will provide 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.  As a result, MassMutual will own
substantially all of the shares of Registrant, probably for a number of years.


The following entities are, or may be deemed to be, controlled by MassMutual
through the direct or indirect ownership of such entities' stock.

                                      C-9
<PAGE>

     
any liability to any entity which is registered as an investment company under
the 1940 Act 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 coverages.  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 from 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 $60 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.,
$10 million of which is underwritten by Continental, Casualty Co., $5 million of
which is underwritten by Federal Insurance Co. 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 (the "1933 Act") 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
1933 Act, and is, 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 1933 Act and will be governed by the
final adjudication of such issue.

ITEM 28: BUSINESS AND OTHER CONNECTIONS OF THE INVESTMENT ADVISER
- -----------------------------------------------------------------

A. THE INVESTMENT ADVISER

MassMutual is the investment adviser for Registrant. MassMutual conducts is a
mutual life insurance company organized as a Massachusetts corporation which was
orginally chartered in 1851.  As a mutual life insurance company, MassMutual has
no shareholders.  MassMutual's primary business  is ordinary life insurance.  It
also provides, directly or through its subsidiaries, a wide range of annuity and
disability products, and pension and pension-related products and services, as
well as investment services to individuals, and corporations and other
institutions, in all 50 states of the United States and the District of
Columbia.  MassMutual is also licensed to transact business in Puerto Rico, and
six provinces of Canada, but has no export sales.  Effective February 29, 1996,
Connecticut Mutual Life Insurance Company merged into MassMutual.

MassMutual's principal lines of business are (i) the Individual Line, which
provides life insurance including variable and universal life insurance,
annuities and disability income insurance to individuals and small businesses;
(ii) Pension Management which provides group pension investment products and
administrative services, primarily to sponsors of tax qualified retirement
plans; (iii) Life and Health Benefits Management, which previously provided
group life and health insurance products and related services to corporations
and other institutions; this line was transferred to a subsidiary in December
1994, and the subsidiary was subsequently sold in March of 1996; and (iv)
MassMutual Investment Management Group, which provides advisory services for
MassMutual's general investment account and separate investment accounts, as
well as for various closed-end and open-end investment companies and external
institutional clients, through its own staff and those of Oppenheimer Funds Inc.
and David L. Babson and Company, Inc., in which MassMutual indirectly owns a
controlling interest.

trust which is an open-end diversified management investment company registered
as such with the Securities and Exchange Commission (the "Commission") pursuant
to the Investment Company Act of 1940, as amended (the "Act"), and the Trust has
appointed MassMutual as the investment adviser for the Fund pursuant to the
terms of an Investment Advisory Agreement (the "Advisory Agreement");

          WHEREAS, the Advisory Agreement provides that MassMutual may, at its
option, subject to approval by the Trustees of the Trust and, to the extent
necessary, shareholders of the Fund, appoint a sub-adviser to assume certain

          WHEREAS, MassMutual and the Sub-Adviser are investment advisers
registered with the Commission as such under the Investment Advisers Act of
1940, as amended (the "Advisers Act"); and

          WHEREAS, MassMutual desires to appoint the Sub-Adviser as its sub-

the terms herein set forth;

          NOW THEREFORE, in consideration of the premises and of the mutual
covenants herein contained, MassMutual and the Sub-Adviser, the parties hereto,
intending to be legally bound, hereby agree as follows:

1.        GENERAL PROVISION.
          ------------------

          MassMutual hereby employs the Sub-Adviser and the Sub-Adviser hereby

          or through MassMutual, the benefit of the Sub-Adviser's best judgment,
          effort, advice and recommendations and shall, at all times conform to,
          and use its best efforts to enable the Fund to conform to:

          (a)  the provisions of the Act and any rules or regulations
               thereunder;

          (b)  any other applicable provisions of state or federal law;
<PAGE>
 
          (c)  the provisions of the Agreement and Declaration of Trust and

               statement under the Investment Company Act or as such policies
               may, from time to time, be amended by the Fund's shareholders;

          (a)  The Sub-Adviser shall, subject to the direction and control by
               the Trust's Board of Trustees or MassMutual, to the extent

               of Trustees, (i) regularly provide investment advice and
               recommendations to the Fund, directly or through MassMutual, with

               purchase and sale of securities; (ii) supervise and monitor
               continuously the investment program of the Fund and the
               composition of its portfolio and determine what securities shall

               provisions of Section 5 hereof, for the purchase of securities

               provide reports on the foregoing to the Board of Trustees at each
               Board meeting.

          (b)  Provided that none of MassMutual, the Fund or the Trust shall be

               terms of this Sub-Advisory Agreement and subject to the
               provisions of Section 5 hereof, the Sub-Adviser may obtain

               improve its investment management services.

          (c)  Provided that nothing herein shall be deemed to protect the Sub-
               Adviser from willful misfeasance, bad faith or gross negligence
               in the performance of its duties, or reckless disregard to its
               obligations and duties under this Sub-Advisory

               corporation and shall not in any way limit or restrict MassMutual
               or the Sub-Adviser or any of their respective directors,
               officers, members, stockholders or employees from buying,
               selling, or trading any securities for its own account or for the
               account of others for whom it or they may be acting, provided
               that such activities will not adversely affect or otherwise
               impair the performance by any party of its duties and obligations
               under this Sub-Advisory Agreement.

          (e)  The Sub-Adviser shall cooperate with MassMutual by providing

               administration for the Fund, including the compilation and
               maintenance of such records with respect to its operations as may
               reasonably be required. The Sub-Adviser shall, at its own
               expense, provide such officers for the Trust as its Board may

5.        PORTFOLIO TRANSACTIONS AND BROKERAGE.
          -------------------------------------

          (a)  The Sub-Adviser is authorized, in arranging the purchase and sale
               of the Fund's publicly-traded portfolio securities, to employ or
               deal with such members of securities exchanges, brokers or
               dealers (hereinafter "broker- dealers"), including "affiliated"
               broker-dealers, as that term is defined in the Act, as may, in
               its best judgment, implement the policy of the Fund to obtain, at
               reasonable expense, the best execution (prompt and reliable
               execution at the most favorable security price obtainable) of the
               Fund's portfolio transactions.

          (b)  The Sub-Adviser may effect the purchase and sale of securities
               (which are otherwise publicly traded) in private transactions on
               such terms and conditions as are customary in such transactions,
               may use a broker in such to effect said transactions, and may
               enter into a contract in which the broker acts either as
               principal or as agent.
 
          (c)  The Sub-Adviser shall select broker-dealers to effect the Fund's
               portfolio transactions on the basis of its estimate of their
               ability to obtain best execution of particular and related
               portfolio transactions. The abilities of a broker-dealer to
               obtain best execution of particular portfolio transaction(s) will
               be judged by the Sub-Adviser on the basis of all relevant factors
               and considerations including, insofar as feasible, the execution
               capabilities required by the transaction or transactions; the
               ability and willingness of the broker-dealer to facilitate the
               Fund's portfolio transactions by participating therein for its
               own account; the importance to the Fund of speed, efficiency or
               confidentiality; the broker-dealer's apparent familiarity with
               sources from or to whom particular securities might be purchased
               or sold; as well as any other matters relevant to the selection
               of a broker-dealer for particular and related transactions of the
               Fund.

6.        DURATION.
          ---------

          Unless terminated earlier pursuant to Section 7 hereof, this Sub-
          Advisory Agreement shall remain in effect until August 2, 1997.
          Thereafter it shall continue in effect from year to year, so long as
          such continuance shall be approved at least annually by the Trust's
          Board of Trustees, including the vote of the majority of the Trustees
          of the Trust who are not parties to this Sub-Advisory Agreement or
          "interested persons" (as defined in the Act) of any such party cast in

          or by the holders of a "majority" (as defined in the Act) of the
          outstanding voting securities of the Fund.

7.        TERMINATION.
          ------------

          This Sub-Advisory Agreement shall terminate automatically upon its
          assignment or in the event upon the termination of the Advisory
          Agreement; it may also be terminated: (i) for cause or with the
          consent of the parties and the Trust by MassMutual or the Sub-Adviser

          other party and the Trust; or (ii) by the Trust at any time without
          penalty upon sixty days' written notice to MassMutual and the Sub-
          Adviser provided that such termination by the Trust shall be directed
          or approved by a vote of a majority of all of the Trustees of the
          Trust then in office or by the vote of the holders of a "majority" of
          the outstanding voting securities of the Fund (as defined in the Act).

8.        DISCLAIMER OF SHAREHOLDER LIABILITY.

          Trust under this Sub-Advisory Agreement are not binding upon any

          broker-dealer to facilitate the Fund's portfolio transactions by
          participating therein for its own account; the importance to the Fund
          of speed, efficiency or confidentiality; the broker-dealer's apparent
          familiarity with sources from or to whom particular securities might
          be purchased or sold; as well as any other matters relevant to the
          selection of a broker-dealer for particular transactions of the Fund.
