been derived from the Funds' financial statements, which have been audited by
Coopers & Lybrand L.L.P., independent accountants.  The information for the
six-month period ended June 30, 1997 is unaudited.  The financial highlights
should be read in conjunction with the financial statements, the notes thereto,
and the unqualified report of independent accountants, which are contained in
the Statement of Additional Information.

Further information about the performance of the Class S shares of the Funds is

LINE OF CREDIT
    
On January 11, 1996, the Trust, on behalf of each Fund, entered 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 0.45%.  Only the
International Equity Fund utilized the line of credit during the year ended
December 31, 1996 and the six months ended June 30, 1997. The table below sets

THE TRUST
    
The Trust is an openend, management investment company 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.  This Prospectus describes  seven separate, diversified
series of shares of the Trust (the "Funds"), each of which has three classes of
shares.  For information regarding the classes of shares of the Funds, see "How
to Purchase, Exchange, and Redeem Shares" below.     
    
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 a
Fund will vary in relation to 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.

  (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.

- ----------------------
/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.

                                       14

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 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./5/  Portfolio Duration
changes may be accomplished primarily through the reinvestment of cash flows and
selective trading.  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 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.

- ------------------
/4/ For example, the four highest ratings of Moody's for debt obligations are 
    Aaa, Aa, A, and Baa (including Baa3).
/5/ See the Glossary for a definition of Duration.

                                       15
<PAGE>
 
  (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.  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.  MassMutual is the Fund's adviser and
Babson is the Sub-Adviser to the Value Equity Sector.  The portfolio of the Fund
is managed by a committee of MassMutual and Babson investment professionals.    

(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. MassMutual is
the Fund's adviser and its Sub-Adviser is Babson.     
    
The Fund utilizes a value-oriented 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 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.  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., which was then an indirect subsidiary of MassMutual ("Concert
Capital"), and, as such, managed the portfolio of the Fund. Formerly, 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.  MassMutual is the Fund's adviser and its Sub-Adviser
is Babson.     
    
The Fund utilizes a value-oriented 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, in the opinion of Babson, 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.  The Fund's
portfolio is managed by George M. Ulrich, Senior Vice President of Babson.  Mr.
Ulrich has been associated with Babson since 1996, Concert Capital (as Senior 
Vice President) from 1993 through 1996 and with MassMutual from 1983 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, securities convertible into common
stocks, and other equity securities, (such as 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
"Investment Practices Of The Funds And Related Risks" below and "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 and its Sub-Adviser is HarbourView. The portfolio of the
Fund is managed by a committee composed of HarbourView investment 
professionals.     

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 simulta-

                                       17
<PAGE>
 
neously 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 seek additional income by making loans of portfolio securities of
not more than 33% of its total assets taken at current value.  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-Advisor 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 relevant markets
(for example, 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.     
    
(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 deems it
    appropriate to do so.     
    
(2) Currency Transactions/6/ - The International Equity Fund may, but will not
    necessarily, engage in foreign currency transactions with counter-parties 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 to be rendered useless, resulting in full currency exposure as
well as incurring transaction costs.



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

                                       18
<PAGE>
 
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 diversifying risks of 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-Advisor'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.  In
addition, high turnover in any Fund could result in additional brokerage
commissions to be paid by the Fund.  See also "Distribution And Taxation"
below.     
    
The Funds may pay brokerage commissions to Advest, Inc. and Jefferies & Co.,
Inc.  A trustee of the Trust is a director of the respective parent companies of
Advest, Inc. and Jefferies & Co., Inc.     

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, AND REDEEM SHARES     
    
FEATURES AND ELIGIBILITY REQUIREMENTS OF EACH CLASS     
    
Each of the Funds offers three different classes of shares to investors: Class
A, Class Y and Class S.  The different classes of a Fund's shares represent
investments in the same portfolio of securities but are subject to different
expenses and will likely have different share prices.  The Class A, Class Y and
Class S shares are offered as follows.     
    
 CLASS A SHARES - Class A shares of each Fund may be purchased by:  defined
 contribution plans and defined benefit plans that qualify under section 401(a)
 of the Internal Revenue Code of 1986, as amended (the "Code"), with Plan 
 Assets/7/ in excess of $2.5 million; tax sheltered annuity plans under Code
 section 403(b) with Plan Assets in excess of $2.5 million; and individual
 retirement accounts described in Code section 408, the assets of which are
 rolled over from qualified plans in connection with a program sponsored by the
 Adviser ("Rollover IRAs"). Class A shares may also be purchased by other
 institutional investors, such as deferred compensation plans described in Code
 section 457, voluntary employees' beneficiary associations described in Code
 section 509(c)(9), other nonqualified deferred compensation plans and other
 institutional or sophisticated investors, in each case with assets in excess of
 $2.5 million or which enter into an agreement with the Adviser or an affiliate
 of the Adviser for those purchases. In addition, Class A shares may be offered
 to present or former officers, directors, trustees and employees (and their
 spouses, parents, children and siblings) of the Trust, the Adviser and its
 affiliates, and retirement plans established by them for their employees.    
    
 CLASS Y SHARES - Class Y shares of each Fund may be purchased by nonqualified
 deferred compensation plans where the employer sponsor enters into an
 administrative services agreement with the Adviser, or an affiliate of the
 Adviser, with respect to the administration of the Plan. Class Y shares may
 also be purchased by defined contribution plans and defined benefit plans under
 Code section 401(a), and tax sheltered annuity plans under Code section 403(b),
 in each case with Plan Assets in excess of $10 million and which enter into an
 administrative services or other agreement with the Adviser or an affiliate of
 the Adviser. Class Y shares may also be purchased by: certain other
 institutional investors with assets in excess of $10 million which enter into
 an agreement with the Adviser or an affiliate of the Adviser; and other
 registered investment companies managed by the Adviser or an affiliate of the
 Adviser, including other series of the Trust.    
    
 CLASS S SHARES - Class S shares of each Fund are available only to separate
 investment accounts of MassMutual ("SIAs") in which corporate qualified plans,
 including defined contribution plans and defined benefit plans, certain
 governmental plans and church or other plans, are or may be permitted to invest
 pursuant to the issuance of group annuity contracts.     
    
CLASS A SHARES - SALES CHARGES AND 12B-1 FEES     
    
Class A shares are sold at net asset value per share without an initial sales
charge.  However, if an Investor redeems any Class A shares within 12 months of
the date on which the Investor first purchased Class A shares, a contingent
deferred sales charge (called the "Class A Contingent Deferred Sales Charge")
may be deducted from the redemption proceeds. If imposed, the Class A Contingent
Deferred Sales Charge will be equal to 1.0% of the lesser of: (1) the aggregate
net asset value of the redeemed shares (not including shares purchased by
reinvestment of dividends or capital gain distributions); and (2) the original
offering price (which is the original net asset value of the redeemed shares).
The Class A Contingent Deferred Sales Charge will not exceed the aggregate
commissions paid on account of all Class A shares of all Funds such Investor
purchased subject to the Class A Contingent Deferred Sales Charge.    
    
In determining whether a Class A Contingent Deferred Sales Charge is payable,
the Fund will first redeem shares that are not subject to the sales charge,
including shares purchased by reinvestment of dividends and capital gains, and
then will redeem other shares in the order purchased.     
    
No Class A Contingent Deferred Sales Charge is charged on exchanges of shares
under "Exchange Privileges and Procedures" (described below). However, if the
shares acquired by exchange are redeemed within 12 months of the initial
purchase of the exchanged shares, the Class A Contingent Deferred Sales Charge
will apply.    
    
The Class A Contingent Deferred Sales Charge is waived in certain cases
described below.     
    
WAIVERS OF THE CLASS A CONTINGENT DEFERRED SALES CHARGES FOR CERTAIN PURCHASERS.
Class A shares purchased by the following Investors are not subject to any Class
A Contingent Deferred Sales Charge:     
    
  (1) the Adviser or its affiliates;     
    
  (2) present or former officers, directors, trustees and employees (and their
      spouses, parents, children and siblings) of the Trust, the Adviser and its
      affiliates, and retirement plans established by them for their 
      employees;

  (3) registered management investment companies, unit investment trusts, or
      separate investment accounts of insurance companies having an agreement
      with the Adviser or the Distributor for those purchases;     
    
  (4) dealers or brokers that have a sales agreement with the Distributor, if
      they purchase shares for their own accounts or for retirement plans for
      their employees;     
    
  (5) dealers, brokers, banks or registered investment advisers that have
      entered into an agreement with the Distributor providing specifically for
      the use of shares of the Fund in particular investment products made
      available to their clients (those clients may be charged a transaction fee

      arrangement with the Adviser or the Distributor; or (k) Plan termination
      or "in service distributions", if the redemption proceeds are rolled over
      directly to a Rollover IRA, the assets of which are invested in the

CLASS A SERVICE PLAN.  Pursuant to a Rule 12b-1 Plan adopted by the Trust. Class
A shares of each Fund pay a service fee at the annual rate of .25% of the Fund's
aggregate average net assets attributable to the Class A shares.  The Trust's
Adviser receives the service fees and may pay all or a portion of them to
brokers and other financial intermediaries, including the Distributor or

choice.  In addition, Class Y shares of each Fund are not subject to deferred
sales charges or to any distribution or service fees.     
    
CLASS S SHARES - NO SALES CHARGES     
    
SIAs purchase Class S shares directly from the Fund without a front-end sales
charge.  Therefore, 100% of an SIA Investor's money is invested in the Fund or
Funds of its choice.  In addition, Class S shares of each Fund are not subject
to any deferred sales charges or any 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 servicing 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.     
    
Plan Investors purchasing group annuity contracts from MassMutual which have one
or more of the Funds as investment options under their Plans ("Group Annuity
Investors") and Rollover IRAs must place their purchase orders with MassMutual
(as servicing 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: (1) includes all information and
documentation necessary to make appropriate Investor, Plan, trustee and/or Plan
Participant (if applicable) allocations to the various Funds and/or other 
investment options under the Plan and (2) 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: (1) immediately available funds,
deposited to the appropriate MassMutual account; and (2) 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./9/    

   
For non-qualified deferred compensation plans eligible to purchase Class Y 
shares that have entered into an administrative services agreement with the 
Adviser, Class Y shares will be purchased directly by the Plan's trustee 
pursuant to the terms of the administrative services agreement. Investors Bank &
Trust Company may serve as a Plan's trustee under the terms of the 
administrative services agreement. Other Investors eligible to Purchase Class A 
and Class Y shares that have entered into an administrative services or other 
agreement with the Adviser must place purchase orders in accordance with the 
terms of such administrative services or other agreement. All other Investors 
must place purchase orders with the Distributor unless the Investor has entered 
into an agreement permitting direct purchases from the Trust.      

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: (1) an Investor has engaged
in excessive trading; (2) the Fund receives or anticipates simultaneous orders
affecting significant portions of the Fund's assets; or (3) 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.     
    
For Group Annuity Investors and Rollover IRAs, exchange requests must be
delivered to MassMutual at its home office. An Investor that has entered into an
administrative services or other agreement with the Adviser must deliver
exchange requests in good form pursuant to the terms of its administrative
services or other agreement. All other Investors must deliver exchange requests
in good form to the Distributor,or the Trust if the Investor has entered into an
agreement permitting direct purchases form the Trust.    
    
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 Transfer Agent. Exchange
requests will not be transmitted to the Transfer Agent until determined to be in
good form./10/    

         

REDEEMING SHARES
    
For Group Annuity Investors and Rollover IRAs, Redemption requests must be 
sent to MassMutual at its home office. An Investor that has entered into an 
administrative services or other agreement with the Adviser must deliver 
redemption requests in good form pursuant to the terms of its administrative 
services or other agreement. All other Investors must deliver redemption 
requests in good form to the Distributor, or the Trust if the Investor has 
entered into an agreement permitting direct purchases from the Trust.     

    
Each Fund redeems its shares at their net asset value as next computed after
receipt by the Transfer Agent of a request for redemption.

<PAGE>

    
Redemption requests will not be transmitted to the Trust's Transfer Agent until
determined to be in good form. 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.     

         

    
The Class A Contingent Deferred Sales Charge may be imposed on certain
redemptions of Class A shares.  For information regarding the Class A Contingent
Deferred Sales Charge, see "Class A Shares - Sales Charges and 12b-1 Fees"
above.     

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 and annuity business in all states of the United States, the District
of Columbia, Puerto Rico and certain Provinces of Canada.  As of June 30, 1997,
MassMutual had consolidated assets in excess of $58.3 billion and consolidated
assets under management in excess of $139 billion, in each case based on
financial statements prepared in accordance with statutory accounting.     

The persons responsible for management of the bond and money market portfolios
of MassMutual are also responsible for managing such investments of the Funds.
Gary E. Wendlandt, Chairman, CEO and Trustee of the Trust, and John V. Murphy,
Trustee of the Trust, are officers of MassMutual, as are Stuart H. Reese,
President of the Trust, Hamline C. Wilson, Vice President and Chief Accounting
and Financial Officer of the Trust, Stephen L. Kuhn, Vice President and
Secretary of the Trust, and Raymond B. Woolson, Treasurer of the Trust.
MassMutual serves as investment manager of each Fund pursuant to a separate
investment management agreement pursuant to which MassMutual is responsible for
providing investment management of the Fund and is authorized to engage in
portfolio transactions on behalf of the Fund, subject to such general or
specific 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

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 with 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 .4752% to .4875% for Class A shares, .2752% to
 .2875% for Class Y shares and .0774% to .0777% for Class S shares. Refer to
"Expense Information" for more detailed information.

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.

average daily net asset value of the Small Cap Value Equity Fund.  MassMutual
pays HarbourView a fee equal to an annual rate of 

                                       23
<PAGE>
 
 .50% of the average daily net asset value of the International Equity Fund.
    
Babson is a wholly-owned subsidiary of DLB Acquisition Corporation,
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. ("OFI"),
which is a wholly-owned subsidiary of Oppenheimer Acquisition Corporation, a
holding company owned in part by senior management of OFI and ultimately
controlled by MassMutual.  HarbourView has operated as an investment adviser
since 1986.  As of April 10, 1997, HarbourView managed assets of approximately
$700 million, including 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 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 & Trust Company 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 & Trust Company assists in
or is responsible for the investment decisions and policies of the Funds.     
    
CONTROL PERSON AND PRINCIPAL HOLDER OF SECURITIES     
    
MassMutual may be deemed a control person of the Trust in that certain separate
investment accounts of MassMutual and the Trust's seed money provided by
MassMutual together constitute 100% of the shares of each class of each Fund of
the Trust as of September 30, 1997.    

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 without 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 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.  Shareholder inquiries should be directed to MassMutual Institutional
Funds, 1295 State Street, Springfield, Massachusetts 01111-0001.     

HOW FUND SHARES ARE PRICED
    
The net asset value (closing price) of each Fund 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 shares of a
class 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 some 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 the Funds may receive different
levels of compensation for selling one class      

                                       24
<PAGE>
     
of shares over another. Class A shares of the Funds, which may be purchased at
the net asset value per share next determined after receipt of a purchase
request in good order, are subject to the service fees under Rule 12b-1, as set
forth and expressed on an annual basis under "Expense Information".    

         

    
MassMutual may directly, or through the Distributor, pay cash compensation to 
registered representatives who are not employees of MassMutual who sell Class A
and Y shares of the Funds. A registered representative selling Class A shares 
may receive: (1) compensation in the first year in an amount equal to 1% of all 
first year contributions; and (2) in each subsequent year, annual compensation 
in an amount equal to 0.25% of the amount invested. A registered representative 
selling Class Y shares to Investors, other than in connection with certain 
non-qualified deferred compensation plans, may receive annual compensation in an
amount equal to: (1) 0.10% of the amount invested if the investment is equal to 
or less than $10 million; or (2) if the investment exceeds $10 million, the sum 
of 0.10% of the first $10 million invested and 0.05% on amounts in excess of $10
million. In connection with the sale of Class y shares to non-qualified deferred
compensation plans that enter into an administrative services agreement with the
Adviser, additional compensation may be paid. In such cases, the aggregate 
annual compensation will be in an amount equal to 0.25% of the amount invested. 
Annual compensation paid on account of sales of Class A and Class Y shares will 
be paid quarterly, in arrears.     

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 investment 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 shortterm capital gains are taxable to the shareholder as
ordinary income whether received in cash or additional shares. Designated long-
term capital gains 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. Under the Taxpayer
Relief Act of 1997, long-term capital gains generally will be subject to a 28%
or 20% tax rate, depending on the holding period in the portfolio investments.
Certain designated dividends may 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 any underlying
Plan Documents or any administrative services or other agreement with the
Adviser, 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 set forth (1) in the case of Class A and Class Y shares, under "Expense
Information," and (2) in the case of Class S shares, in the Fee Table of the
Trust's initial prospectus which was effective October 3, 1994. The anticipated 
expenses of the Class S shares of each Fund as set forth in the Trust's initial 
prospectus were as follows: 0.516% for the Prime Fund; 0.519% for the Short-Term
Bond Fund; 0.513% for the Core Bond Fund; 0.512% for the Balanced Fund; 0.5067%
for the Value Equity Fund; 0.611% for the Small Cap Value Equity Fund; and
1.002% for the International Equity Fund. These fees and expenses include, in
the case of Class A shares, Rule 12b-1 fees and contingent deferred sales
charges, and in the case of Class S shares, any charges at the SIA level.     
    
Performance data for Class A and Class Y shares for the period from October 3,
1994 until the date on which such class is initially offered for sale will be
based on the performance of Class S shares adjusted downward to take into
account the deduction of the higher operating expenses to which Class A and
Class Y shares are subject. All performance data reflects the management fee
waiver in effect for Class S shares through May 1, 1997.    
    
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 1940 Act, the SIAs performance      

                                       25
<PAGE>
     
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. Investors that enter into an administrative services
or other agreement with the Adviser may also be subject to certain charges as
set forth in their respective agreements. Total return figures would be lower 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 S shares will be provided net of
the Fund and any 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.

The quoted performance data includes the performance of the Separate Investment
Accounts (SIAs) for the period before the Trust's Registration Statement became
effective.  The SIAs were not registered under the 1940 Act and therefore were
not subject to certain investment restrictions imposed by the Act.  If the SIAs
had been registered under the 1940 Act, their performance may have been
adversely affected.

GLOSSARY

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.  As a measure of a fixed-income security's cash flow, duration is an
alternative to the concept of "term to maturity" in assessing the price
volatility associated with changes in interest rates.  Generally, the longer the
duration, the more volatility an investor should expect.  For example, the
market price of a bond with a duration of two years would be expected to decline
2% if interest rates rose 1%.  Conversely, the market price of the same bond
would be expected to increase 2% if interest rates fell 1%.  The market price of
a bond with a duration of four years would be expected to increase or decline
twice as much as the market price of a bond with a two-year duration.  Duration
measures a security's maturity in terms of the average time required to receive
the present value of all interest and principal payments as opposed to its term
to maturity.  The maturity of a security measures only the time until final
payment is due; it does not take account of the pattern of a security's cash
flow over time, which would include how cash flow is affected by prepayments and
by changes in interest rates.  Incorporating a security's yield, coupon interest
payments, final maturity and option features into one measure, duration is
computed by determining the weighted average maturity of a bond's cash flows,
where the present values of the cash flows serve as weights.  Determining
duration may involve the Adviser's estimates of future economic parameters,
which may vary from actual future values.     

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, trustee, institutional
investor, insurance company separate investment account and/or any other person
or entity described in the Prospectus as an eligible purchaser of shares, 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
Statement of Additional Information.  For example, the four investment grade
ratings in descending order for debt securities as rated by Moody's are Aaa, Aa,
A and Baa -- including Baa3.  The four investment grade ratings for debt
securities as rated by S&P are AAA, AA, A and BBB -- including BBB-.  For
commercial paper, Moody's two highest ratings are P-1 and P-2 and S&P's two
highest ratings are A-1 and A-2.
    
PLAN: refers to all defined contribution and defined benefit retirement plans
and any other employee retirement arrangement that invests in the Funds,
including non-qualified deferred compensation plans and tax sheltered annuity
plans.     
    
PLAN ASSETS: assets held by the Plan trustee of a particular Plan.     
    
PLAN PARTICIPANT: includes active, deferred and suspended Plan Participants on
whose behalf Plan Assets are invested, as well as any other individual included
in the computation of active participants under the appropriate Form 5500 filed
with the Internal Revenue Service, if applicable.     
    
PLAN DOCUMENTS: refer to the documents that created and are related to a
particular employee retirement benefit plan.  These documents might include
trust documents, insurance contracts (including group annuity contracts),
administrative service agreements and other agreements providing for the
provision of services or benefits for the plan and its participants.     
    
U.S. GOVERNMENT SECURITIES: include obligations issued, sponsored, assumed or
guaranteed as to principal and interest by the Government of the United States,
its agencies and instrumentalities, and securities backed by such obligations,
including FHA/VA guaranteed mortgages.

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

    
MassMutual Institutional Funds (the "Trust") is a professionally managed, open-
end investment company. This Statement of Additional Information describes the
following seven separate diversified series of the Trust: (1) MassMutual Prime
Fund, (2) MassMutual ShortTerm 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
than 50% of the outstanding shares of that Fund). The Board of Trustees of the
Trust may adopt new or amend or delete existing non-fundamental investment
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
longterm capital appreciation will be stressed.
    
Currency Transactions - The Fund may, but will not necessarily, 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, an 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 ShortTerm Bond Fund or the Core Bond Fund dispose 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 ShortTerm 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 seek additional income by making loans of portfolio securities of not
more than 33% of its net assets taken at current market value. 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 in 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. 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 & 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


                                      B-6
<PAGE>
 
volatile; and (c) the possible need to defer closing out certain positions to
avoid adverse tax consequences.  More specific risks are set forth below.

     (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-fundental 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 or its delegate under applicable rules adopted by the
Securities and Exchange Commission (the "SEC"). 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

                                      B-7
<PAGE>
 
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 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 generally produce current recognition of gain for federal income
tax purposes on the constructive sale of securities "in the box" prior to the
time 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.

                                      B-8
<PAGE>
 
     (4) Make short sales, except for sales "against the box."

     (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.


                                      B-9
<PAGE>
 
         
     (3) To the extent that shares of a Fund are purchased or otherwise acquired
     by an acquiring company that is part of the same group of investment
     companies as the Trust in reliance on Section 12(d)(1)(G) of the 1940 Act,
     acquire any securities of registered open-end investment companies or
     registered unit investment trusts in reliance or Section 12(d)(1)(F) or
     Section 12 (d)(1)(G) of the 1940 Act.

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

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 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.

together constitute 100% of the shares of each class of each Fund of the Trust
as of September 30, 1997.     

                       INVESTMENT MANAGER AND SUBADVISERS
                       ----------------------------------

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.Y., a corporation that
issued Collateralized Bond Obligations on or about May 1, 1991;      

                                      B-15

MassMutual Corporate Value Partners, a partnership formed in 1994 to provide
investment opportunities on a leverage basis in the public or 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:

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 at an annual rate based upon the average
daily net assets of the applicable class of shares of the Fund which range from
 .4752% to .4875% for Class A shares; .2752% to .2875% for Class Y shares; and
 .0774% to .0777% for Class S shares.

INVESTMENT SUBADVISERS
    
Securities held by the Funds are also frequently held by MassMutual investment
accounts and by other investment companies and accounts for which MassMutual,
Babson or HarbourView 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      

                                      B-17
<PAGE>
 
    
the Funds. In some cases, however, this procedure could have a detrimental
effect on the price and amount of a security available to a Fund or the price at
which a security may be sold. It is the opinion of the Trust's management that
such execution advantage and the desirability of retaining MassMutual, Babson,
and HarborView 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. ("OFI"), which is a wholly owned subsidiary of
Oppenheimer Acquisition Corporation, a holding company owned in part by senior
management of OFI 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 OppenheimerFunds Distributor,
Inc. (the "Distributor") pursuant to a Distribution Agreement with the Trust
dated [October 24, 1997].  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. MML Investor Services, Inc. serves as the 
sub-distributor to the Trust pursuant to an agreement with the Distributor dated
September 8, 1997.     

    
     The Distribution Agreement will continue in effect for successive one-year 
periods, provided that each such continuance is specifically approved (i) by the
vote of a majority of the Trustees or by a vote of a majority of the shares of 
the Trust; and (ii) by a majority of the Trustees who are not parties to the 
Distribution Agreement or interested persons of the Trust (as defined in the 
1940 Act), cast in person at a meeting called for the purpose of voting on such 
approval.     
    
Administrative Services Plans for Class A Shares

     The Trust has adopted, with respect to the Class A shares of each Fund, an
Administrative Services Plan (each such plan, a "Plan") pursuant to Rule 12b-1
under the 1940 Act. 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 Plans, approved the
Plan on [Date]. Under the terms of each Plan, the Trust is permitted to 
reimburse, out of the assets attributable to the Class A shares of each 
applicable Fund, in an amount up to 0.25% on an annual basis of the average 
aggregate net assets of that class. MassMutual for the provision of services to 
Class A shareholders by it, the Distributor and investment dealers [and to 
reimburse certain other distribution related expenses]. These services may 
include, but are not limited to, the following: providing facilities to answer 
questions from prospective investors about a Fund; receiving and answering 
correspondence, including requests for prospectuses and statements of additional
information; preparing, printing and delivering prospectuses and shareholder 
reports to prospective shareholders; complying with federal and state 
securities laws pertaining to the sale of Class A shares; assisting investors in
completing application forms and selecting dividend and other account options; 
receiving, aggregating and processing shareholder orders; furnishing shareholder
sub-accounting; providing and maintaining elective shareholder services such as 
check writing and wire transfer services; providing and maintaining 
pre-authorized investment plans; communicating periodically with shareholders; 
acting as the sole shareholder of record and nominee for shareholders; 
maintaining accounting records for shareholders; and answering questions and 
handling correspondence from shareholders about their accounts.

     Each Plan provides that it may not be amended to materially increase the 
costs which Class A shareholders may bear under the Plan without the approval of
a majority of the outstanding Class A shares of the Fund.

     Each Plan provides that it may not take effect until approved by vote of a 
majority of both (i) the Trustees of the Trust and (ii) the Trustees of the 
Trust who are not interested persons of the Trust and have no direct or indirect
financial interest in the operation of the Plan or any agreements related to it.
Each Plan provides that it shall continue in effect so long as such continuance 
is specifically approved at least annually by (i) Trustees of the Trust and (ii)
Trustees of the Trust who are not interested persons of the Trust and have no 
direct or indirect financial interest in the operation of the Plan or any 
agreements related to it. Each Plan provides that the Distributor and MassMutual
shall provide to the Trustees, and the Board shall review at least quarterly, a 
written report of the amounts so expended and the purposes for which such 
expenditures were made.

     Rules of the NASD limit the amount of distribution fees that may be paid by
mutual funds. "Service fees," defined to mean fees paid for providing 
shareholder services or the maintenance of accounts (but not transfer agency 
services) are not subject to the limits. The Trust believes that most, if not 
all, of the fees paid pursuant to the Plan will qualify as "service fees" and 
therefore will not be limited by NASD rules.

     The Plans were not in effect prior to the date of this Statement of 
Additional Information and no payments were made thereunder in prior fiscal 
periods.     

         

    
Under 12b-1 plans for classes of shares that no longer exist, the Trust paid
distribution and service fees in 1996 of approximately $856 for the Prime Fund,
$896 for the Short-Term Bond Fund, $1,098 for the Core Bond Fund, $1,154 for the
Balanced Fund, $1,074 for the Value Equity Fund, $1,195 for the Small Cap Value
Equity Fund, and $915 for the International Equity Fund, of which approximately
$4,897 was paid to the Distributor for distribution services and approximately
$2,292 was paid to MassMutual for sales related expenses plans.

                      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 overthecounter
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
brokerdealers 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 brokerdealers, 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.

                                      B-19
<PAGE>
 
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 $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.  Approximately $24,000 of the brokerage commissions paid
by the Funds for the fiscal year ended December 31, 1996 were paid to Jefferies
& Co., Inc.  A Trustee of the Trust is a director of the parent company of
Jefferies & Co., Inc.      

The Prime Fund, ShortTerm 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, the Trust 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 90day 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.  The NYSE is
not open for trading on New Year's Day, Martin Luther King, Jr. Day, President's
Day, Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving Day
and Christmas Day and on occasion is closed early or entirely due to weather or
other conditions.

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 overthecounter securities not
so listed, the last reported bid price.  Debt securities (other than shortterm
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 institutionalsize 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      

- -------------------------------
    
/1/ "Investor" includes a plan sponsor, plan fiduciary, trustee, institutional
investor, insurance company separate investment account and/or any other person
or entity described in the Prospectus as an eligible purchaser of shares, 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.     

                                      B-20

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 some
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
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 S shares will be provided net of any 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.

                                      B-21
<PAGE>
 
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
voluntary partial waiver of management fee by MassMutual, which terminated May
1, 1997  ("Standardized Total Return Without Reduction in Management Fee").  See
"Financial Highlights" in the Prospectus.  Each investment performance figure
will be carried to the nearest hundredth of one percent.      

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.

Bond Fund and Core Bond Fund for the 30day period ended June 30, 1997.

                                    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; and (b)
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, 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 total 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.      

                                      B-22
<PAGE>
 
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.  Under the
Taxpayer Relief Act of 1997, long-term capital gains generally will be subject
to a 28% or 20% tax rate, depending on the holding period in the portfolio
investment.      

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.  In addition, the
ability of shareholders to claim a foreign tax credit is subject to a holding
period requirement.  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.  Investment
by a Fund in "passive foreign investment companies" could subject the Fund to
a U.S. federal income tax or other charge on the proceeds from the sale of its
investment in such a company; however, this tax can be avoided by making an
election to mark such investments to market annually or to treat the passive
foreign investment company as a "qualified electing fund."

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 capital asset.  Under the Taxpayer Relief Act
of 1997, long-term capital gains generally will be subject to a 28% or 20% tax
rate depending on the Investor's holding period in Fund shares.  However, 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      

                                      B-23
<PAGE>
 
    
paid to the shareholder with respect to such shares. 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 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.    
 
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

1.  The Trust

MassMutual Institutional Funds (the "Trust") is registered under the 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 separate series of shares (each individually referred to as a
"Fund" or collectively as the "Funds"), each having four classes of shares:
Class 1, Class 2, Class 3 and Class 4. 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"). 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
including defined contribution plans and defined benefit plans are permitted to
invest pursuant to the issuance of group annuity contracts. The Funds are
MassMutual Prime Fund ("Prime Fund"), MassMutual Short-Term Bond Fund
("Short-Term Bond Fund"), MassMutual Core Bond Fund ("Core Bond Fund"),
MassMutual Balanced Fund ("Balanced Fund"), MassMutual Value Equity Fund ("Value
Equity Fund"), MassMutual Small Cap Value Equity Fund ("Small Cap Value Equity
Fund"), and MassMutual International Equity Fund ("International Equity Fund"),
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.

                                                                              67

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.

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 International Equity Fund under these financial instruments
at December 31, 1996 is as follows:

</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.


3.   Management Fees and Other Transactions With Affiliates


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:

</TABLE> 

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 Capital became co-employees of Babson. At the
time, both Concert Capital and Babson were wholly-owned subsidiaries of DLB
Acquisition Corporation, a controlled subsidiary of MassMutual. Concert Capital
merged with and into Babson effective December 31, 1996.

MassMutual pays Babson a fee equal to an annual rate of .13% of the average
daily net asset value of the Value Equity Fund and 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.


Administration Fees


Under separate administrative and shareholder services agreements 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 receives an administrative services fee monthly based
upon the average daily net assets of the applicable class of shares of the Fund
at the following annual rates:

OppenheimerFunds Distributor, Inc. ("Oppenheimer") acts as distributor to each
Fund. MML Investor Services, Inc. ("MMLISI") serves as sub-distributor to each
Fund. MassMutual has a controlling interest in OppenheimerFunds and MMLISI is a
wholly owned subsidiary of MassMutual. Oppenheimer is paid a distribution fee
with respect to Class 1 and Class 2 at the annual rate of .40% and .15%,
respectively, of the value of average daily net assets attributable to those
classes of shares of which a portion is subsequently allocated to MMLISI. The
Funds do not pay any fees directly to MMLISI. MassMutual is also paid a fee for
shareholder services with respect to Class 1 shares of the Funds at the annual
rate of .25% of the value of the average daily net assets of the respective
class of each Fund. These fees are authorized pursuant to separate service and
distribution plans for each of the classes of shares adopted by the Funds
pursuant to Rule 12b-1 under the Investment Company Act and are used by
Oppenheimer to cover expenses primarily intended to result in the sale of those
shares of the Funds.

6.  Foreign Securities

The International Equity Fund invests substantially all of its 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.

7.  Federal Income Tax Information

At December 31, 1996, the cost of securities and the unrealized appreciation
(depreciation) in the value of investments owned by the Funds, as computed on a

  December 31, 1994.

***Per share amount calculated on the average shares method, which more
   appropriately presents the per share data for the period since the use of the
   undistributed income method does not accord with the results of operations.

@Employee retirement benefit plans that invest plan assets in the Separate
 Investment Accounts (SIAs) may be subject to certain charges as set forth in
 their respective Plan Documents. Total return figures would be lower for the
 periods presented if they reflected these charges.

*Annualized

**For the period from October 3, 1994 (commencement of operations) through
December 31, 1994.

(a)Average commission rate paid is computed by dividing the total amount of
   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.

@  Employee retirement benefit plans that invest plan assets in the Separate
   Investment Accounts (SIAs) may be subject to certain charges as set forth  in
   their respective Plan Documents. Total return figures would be lower for the
   periods presented if they reflected these charges.

**For the period from October 3, 1994 (commencement of operations) through
December 31, 1994.
(a)Average commission rate paid is computed by dividing the total amount of
   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.  
@  Employee retirement benefit plans that invest plan assets in the Separate
   Investment Accounts (SIAs) may be subject to certain charges as set forth in
   their respective Plan Documents. Total return figures would be lower for the
   periods presented if they reflected these charges.

*Annualized
**For the period from October 3, 1994 (commencement of operations) through
December 31, 1994.

(a)Average commission rate paid is computed by dividing the total amount of
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. The average broker commission rate will vary depending on the
markets in which trades are executed.

(a)Average commission rate paid is computed by dividing the total amount of
   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. The average broker commission rate will vary
   depending on the markets in which trades are executed.
@  Employee retirement benefit plans that invest plan assets in the Separate
   Investment Accounts (SIAs) may be subject to certain charges as set forth in
   their respective Plan Documents. Total return figures would be lower for the
   periods presented if they reflected these charges.

1.      The Trust

MassMutual Institutional Funds (the "Trust") is registered under the 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 separate series of shares (each individually referred to as a
"Fund" or collectively as the "Funds"), each having four classes of shares:
Class 1, Class 2, Class 3 and Class 4. 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"). 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,
including defined contribution plans and defined benefit plans, are permitted to
invest pursuant to the issuance of group annuity contracts. The Funds are
MassMutual Prime Fund ("Prime Fund"), MassMutual Short-Term Bond Fund
("Short-Term Bond Fund"), MassMutual Core Bond Fund ("Core Bond Fund"),
MassMutual Balanced Fund ("Balanced Fund"), MassMutual Value Equity Fund ("Value
Equity Fund"), MassMutual Small Cap Value Equity Fund ("Small Cap Value Equity
Fund"), and MassMutual International Equity Fund ("International Equity Fund"),
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.

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.


                                                                              69

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 International Equity Fund under these financial instruments
at June 30, 1997 is as follows:

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
June 30, 1997, 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.


3.   Management Fees and Other Transactions With Affiliates

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:

</TABLE> 
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 Capital became co-employees of Babson. At the
time, both Concert Capital and Babson were wholly-owned subsidiaries of DLB
Acquisition Corporation, a controlled subsidiary of MassMutual. Concert Capital
merged with and into Babson effective December 31, 1996.
 
MassMutual pays Babson a fee equal to an annual rate of .13% of the average
daily net asset value of the Value Equity Fund and 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.

Administration Fees

Under separate administrative and shareholder services agreements 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 receives an administrative services fee monthly based
upon the average daily net assets of the applicable class of shares of the Fund
at the following annual rates:

Distribution and Service Fees
    
OppenheimerFunds Distributor, Inc. ("Oppenheimer") acts as distributor to each
Fund. MML Investor Services, Inc. ("MMLISI") serves as sub-distributor to each
Fund. MassMutual has a controlling interest in OppenheimerFunds, and MMLISI is a
wholly owned subsidiary of MassMutual. Oppenheimer is paid a distribution fee
with respect to Class 1 and Class 2 at the annual rate of .40% and .15%,
respectively, of the value of average daily net assets attributable to those
classes of shares of which a portion is subsequently allocated to MMLISI. The
Funds do not pay any fees directly to MMLISI. MassMutual is also paid a fee for
shareholder services with respect to Class 1 shares of the Funds at the annual
rate of .25% of the value of the average daily net assets of the respective
class of each Fund. These fees are authorized pursuant to separate service and
distribution plans for each of the classes of shares adopted by the Funds
pursuant to Rule 12b-1 under the Investment Company Act and are used by
Oppenheimer to cover expenses primarily intended to result in the sale of those
shares of the Funds.     

Expense Limitations

For the period January 1, 1997 to April 30, 1997, MassMutual voluntarily agreed
to waive a portion of its management fee to the extent that the aggregate annual
operating expenses incurred during the year exceed the following percentages of

6.   Foreign Securities

The International Equity Fund invests substantially all of its 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.

7.   Federal Income Tax Information

At June 30, 1997, the cost of securities and the unrealized appreciation
(depreciation) in the value of investments owned by the Funds, as computed on a
Federal income tax basis, are as follows:

the Registration Statement filed via EDGAR April 28, 1997.
    
/3/To be filed by amendment.      

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 

                                      C-3

</TABLE>      

Item 27: Indemnification
- ------------------------

Article VIII of Registrant's Agreement and Declaration of Trust provides for the
indemnification of Registrant's Trustees and officers. Registrant undertakes to
apply the indemnification provisions of its Agreement and Declaration of Trust
in a manner consistent with Securities and Exchange Commission Release No.
IC-11330 so long as the interpretation of Section 17(h) and 17(i) of the
Investment Company Act of 1940 (the "1940 Act") set forth in such Release shall
remain in effect and be consistently applied.

Trustees and officers of Registrant are also indemnified by MassMutual pursuant
to its by-laws which apply to subsidiaries, including Registrant. No
indemnification is provided with respect to any liability to any entity which is
registered as an investment company under the 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 the Registrant. MassMutual is a mutual
life insurance company organized as a Massachusetts corporation which was
originally 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

                                     SHARES

Division of Beneficial Interest
- -------------------------------

     Section 1.  The Shares of the Trust shall be issued in one or more series
     ---------                                                                
as the Trustees may, without Shareholder approval, authorize.  The Trustees may,
without Shareholder approval, divide the Shares of any series into two or more
classes, Shares of each such class having such preferences or special or
relative rights or privileges (including conversion rights, if any) as the
Trustees may determine and as are not inconsistent with any provision of this
Declaration of Trust.  Each series shall be preferred over all other series in
respect of the assets allocated to that series.  The beneficial interest in each
series shall at all times be divided into Shares, without par value unless the
Trustees specify otherwise, each of which shall, except as the Trustees may
otherwise authorize in the case of any series that is divided into two or more
classes, represent an equal proportionate interest in the series with each other
Share of the same series, none having priority or preference over another.  The
number of Shares authorized shall be unlimited, and the Shares so authorized may
be represented in part by fractional shares.  The Trustees may from time to time
divide or combine the Shares of any series or class into a greater or lesser
number without thereby changing the proportionate beneficial interests in the
series or class.

Ownership of Shares
- -------------------

     Section 2.  The ownership of Shares shall be recorded on the books of the
     ---------                                                                
Trust or its transfer or similar agent.  No certificates certifying the
ownership of Shares shall be issued except as the Trustees may otherwise
determine from time to time.  The Trustees may make such rules as they consider
appropriate for the issuance of Share certificates, the transfer of Shares and
similar matters.  The record books of the Trust as kept by the Trust or any
transfer or similar agent of the Trust, as the case may be, shall be conclusive
as to who are the Shareholders of each series and class and as to the number of
Shares of each series and class held from time to time by each Shareholder.

Investments in the Trust; Assets of the Series
- ----------------------------------------------

     Section 3.  The Trustees may accept investments in the Trust from such
     ---------                                                             
persons and on such terms and, subject to any requirements of law, for such
consideration, which may consist of cash or tangible or intangible property or a
combination thereof, as they from time to time authorize.  When Shares have been
issued for such consideration, such Shares shall be fully paid and
nonassessable.

                                      -3-
<PAGE>
 
     All consideration received by the Trust for the issue or sale of Shares of
each series, together with all income, earnings, profits and proceeds thereof,
including any proceeds derived from the sale, exchange or liquidation thereof,
and any funds or payments derived from any reinvestment of such proceeds in
whatever form the same may be, shall irrevocably belong to the series of Shares
with respect to which the same were received by the Trust for all purposes,
subject only to the rights of creditors, and shall be so handled upon the books
of account of the Trust and are herein referred to as "assets of" such series.

No Preemptive or Appraisal Rights; Derivative Actions
- -----------------------------------------------------

     Section 4.  Shareholders shall have no preemptive or other right to
     ---------                                                          
receive, purchase or subscribe for any additional Shares or other securities
issued by the Trust and shall have no appraisal rights with respect to Shares
owned by them.  No action may be brought by a Shareholder on behalf of the Trust
or a particular series of the Trust unless a prior demand regarding such matter
has been made on the Trustees and the Shareholders of the Trust or such series.

Status of Shares and Limitation of Personal Liability
- -----------------------------------------------------

     Section 5.  Shares shall be deemed to be personal property giving only the
     ---------                                                                 
rights provided in this instrument.  Every Shareholder by virtue of having
become a Shareholder shall be held to have expressly assented and agreed to the
terms hereof and to have become a party hereto.  The death of a Shareholder
during the continuance of the Trust shall not operate to terminate the same nor
entitle the representative of any deceased Shareholder to an accounting or to
take any action in court or elsewhere against the Trust or the Trustees, but
only to the rights of said decedent under this Trust.  Ownership of Shares shall
not entitle the Shareholder to any title in or to the whole or any part of the
Trust property or right to call for a partition or division of the same or for
an accounting, nor shall the ownership of Shares constitute the Shareholders
partners.  Neither the Trust nor the Trustees, nor any officer, employee or
agent of the Trust, shall have any power to bind personally any Shareholder, nor
except as specifically provided herein to call upon any Shareholder for the
payment of any sum of money or assessment whatsoever other than such as the
Shareholder may at any time personally agree to pay.

Election; Removal
- -----------------

     Section 1.  The number of Trustees shall be fixed by the Trustees, except
     ---------                                                                
that, subsequent to any sale of Shares pursuant to a public offering, there
shall be not less than three Trustees.  Any vacancies occurring in the Board of
Trustees may be filled by the Trustees if, immediately after filling any such
vacancy, at least two-thirds of the Trustees then holding office shall have been
elected to such office by the Shareholders.  In the event that at any time less
than a majority of the Trustees then holding office were elected to such office
by the Shareholders, the Trustees shall call a meeting of Shareholders for the
purpose of electing Trustees.  Each Trustee elected by the Trustees shall serve
until the next meeting of Shareholders called for the purpose of electing
Trustees and until the election and qualification of his or her successor, or
until he or she sooner dies, resigns or is removed.  Each Trustee elected by the
Shareholders shall serve until he or she dies, resigns or is removed.  The
initial Trustees, each of whom shall serve until he or she dies, resigns or is
removed, shall be Stephen L. Kuhn and such other persons as the Trustee or
Trustees then in office shall, prior to any sale of Shares pursuant to a public
offering, appoint.  By vote of a majority of the Trustees then in office, the
Trustees may remove a Trustee with or without cause.  At any Shareholders'
meeting called for the purpose, a Trustee may be removed, with or without cause,
by vote of the holders of two-thirds of the votes represented by outstanding
Shares.

Effect of Death, Resignation, etc. of a Trustee
- -----------------------------------------------

     Section 2.  The death, declination, resignation, retirement, removal or
     ---------                                                              
incapacity of the Trustees, or any one of them, shall not operate to annul the
Trust or to revoke any existing agency created pursuant to the terms of this
Declaration of Trust.

Powers

     Section  3.  Subject to the provisions of this Declaration of Trust, the
     ----------                                                              
business of the Trust shall be managed by the Trustees, and they shall have all
powers necessary or convenient to carry out that responsibility.  Without
limiting the foregoing, the Trustees may adopt Bylaws not inconsistent with this
Declaration of Trust providing for the conduct of the business of the Trust and
may amend and repeal them to the extent that such Bylaws do not reserve that
right to the Shareholders; they may fill vacancies in their number, including
vacancies resulting from increases in their number, and may elect and remove
such officers and appoint and terminate such agents as 

                                      -5-

they consider appropriate; they may appoint from their own number, and
terminate, any one or more committees consisting of two or more Trustees,
including an executive committee which may, when the Trustees are not in
session, exercise some or all of the power and authority of the Trustees as the
Trustees may determine; they may appoint an advisory board, the members of which
shall not be Trustees and need not be Shareholders; they may employ one or more
custodians of the assets of the Trust and may authorize such custodians to
employ subcustodians and to deposit all or any part of such assets in a system
or systems for the central handling of securities; retain a transfer agent or a
Shareholder services agent, or both; provide for the distribution of Shares by
the Trust, through one or more principal underwriters or otherwise; set record
dates for the determination of Shareholders with respect to various matters; and
in general delegate such authority as they consider desirable to any officer of
the Trust, to any committee of the Trustees and to any agent or employee of the

     provided that any liabilities or expenses incurred by a particular series
     of Shares shall be payable solely out of the assets of that series; and to
     the extent necessary or appropriate to give effect to the preferences and
     special or relative rights and privileges of any classes of Shares, to
     allocate assets, liabilities, income and expenses of a series to a
     particular class of Shares of that series or to apportion the same among
     two or more classes of Shares of that series;

     the Trust property or any part thereof to secure any of or all of such
     obligations or obligations incurred pursuant to subparagraph (k) hereof;

          (m) To purchase and pay for entirely out of Trust property such
     insurance as they may deem necessary or appropriate for the conduct of the
     business, including, without limitation, insurance policies insuring the

     advisers or managers, principal underwriters or independent contractors of
     the Trust individually against all claims and liabilities of every nature
     arising by reason of holding, being or having held any such office or

     by any such person as Shareholder, Trustee, officer, employee, agent,
     investment adviser or manager, principal underwriter or independent
     contractor, including any action taken or omitted that may be determined to

     purchasing of life insurance and annuity contracts as a means of providing
     such retirement and other benefits, for any or all of the Trustees,
     officers, employees and agents of the Trust.

     The Trustees shall not in any way be bound or limited by any present or
future law or custom in regard to investments by Trustees.

     Except as otherwise provided herein or from time to time in the Bylaws, any
action to be taken by the Trustees may be taken by a majority of the Trustees
present at a meeting of the Trustees (a quorum being present), within or without
Massachusetts, including any meeting held by means of a conference telephone or
other communications equipment by means of which all persons participating in
the meeting can hear each other at the same time, and participation by such
means shall constitute presence in person at a meeting, or by written consents
of a majority of the Trustees then in office.

contract may contain such other terms interpretive of or in addition to said
requirements and restrictions as the Trustees may determine, including, without

in the investments of the Trust or any series of Shares.  The Trustees may also,
at any time and from time to time, contract with Oppenheimer Management

                    SHAREHOLDERS' VOTING POWERS AND MEETINGS

Voting Powers

     Section 1.  The Shareholders shall have power to vote only (i) for the
     ---------                                                             
election or removal of Trustees as provided in Article IV, Section 1, (ii) with
respect to any Adviser as provided in Article IV, Section 6, (iii) with respect
to any termination of this Trust to the extent and as provided in Article IX,
Section 4, (iv) with respect to any amendment of this Declaration of Trust to
the extent and as provided in Article IX, Section 7 and (v) with respect to such
additional matters relating to the Trust as may be required by law, this
Declaration of Trust, the Bylaws or any registration of the Trust with the
Securities and Exchange Commission (or any successor agency) or any state, or as
the Trustees may consider necessary or desirable.

     Holders of Shares of each series or class shall be entitled to one vote for
each dollar (or a proportionate fractional vote for each fraction of a dollar)
of net asset value per Share of each series or class for each Share held as to
any matter on which such Shares are entitled to vote.  Notwithstanding any other
provision of this Declaration of Trust, on any matter 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 series or class except: (1)
when required by the 1940 Act or when the Trustees shall have determined that
the matter affects one or more series or classes materially differently, Shares
shall be voted by individual series or class; and (2) when the Trustees have
determined that the matter affects 

                                     -10-
<PAGE>
 
only the interests of one or more series or classes, then only Shareholders of
such series or classes shall be entitled to vote thereon. There shall be no
cumulative voting in the election of Trustees.

     Shares may be voted in person or by proxy.  A proxy with respect to Shares
held in the name of two or more persons shall be valid if executed by any one of
them unless at or prior to exercise of the proxy the Trust receives a specific
written notice to the contrary from any one of them.  A proxy purporting to be
executed by or on behalf of a Shareholder shall be deemed valid unless
challenged at or prior to its exercise and the burden of proving invalidity
shall rest on the challenger.  At all meetings of Shareholders, unless
inspectors of election have been appointed, all questions relating to the
qualification of voters and the validity of proxies and the acceptance or
rejection of votes shall be decided by the chairman of the meeting.  Unless
otherwise specified in the proxy, the proxy shall apply to all Shares of each
series of the Trust owned by the Shareholder.

     Until Shares are issued, the Trustees may exercise all rights of
Shareholders and may take any action required by law, this Declaration of Trust
or the Bylaws to be taken by Shareholders.

Meetings
- --------

     Section 2.  No annual or regular meeting of Shareholders is required.
     ---------                                                             
Meetings of Shareholders of the Trust or of any series or class may be called by
the Trustees or such other person or persons as may be specified in the Bylaws
and held from time to time for the purpose of taking action upon any matter
requiring the vote or the authority of the Shareholders of the Trust or any
series or class as herein provided or upon any other matter deemed by the
Trustees to be necessary or desirable.  Meetings of Shareholders of the Trust or
of any series or class shall be called by the Trustees or such other person or
persons upon written application as may be specified in the Bylaws.  The
Shareholders shall be entitled to at least seven days' written notice of any
meeting of the Shareholders.

Quorum and Required Vote
- ------------------------

     Section 3.  Shares representing thirty percent (30%) of the votes entitled
     ---------                                                                 
to vote shall be a quorum for the transaction of business at a Shareholders'
meeting, except that where any provision of law or of this Declaration of Trust
permits or requires that holders of any series or class shall vote as a series
or class, then Shares representing thirty percent (30%) of the votes of that
series or class entitled to vote shall be necessary to constitute a quorum for
the transaction of business 

                                     -11-
<PAGE>
 
by that series or class. Any lesser number, however, shall be sufficient for
adjournments. Any adjourned session or sessions may be held within a reasonable
time after the date set for the original meeting without the necessity of
further notice. Except when a larger vote is required by any provision of this
Declaration of Trust or the Bylaws, Shares representing a majority of the votes
voted shall decide any questions and a plurality shall elect a Trustee, provided
that where any provision of law or of this Declaration of Trust permits or
requires that the holders of any series or class shall vote as a series or
class, then Shares representing a majority of the votes of that series or class
voted on the matter (or a plurality with respect to the election of a Trustee)
shall decide that matter insofar as that series or class is concerned.

Action by Written Consent
- -------------------------

     Section 4.  Any action taken by Shareholders may be taken without a meeting
     ---------                                                                  
if Shares representing a majority of the votes entitled to vote on the matter
(or such larger proportion thereof as shall be required by any express provision
of this Declaration of Trust or the Bylaws or by law) consent to the action in
writing and such written consents are filed with the records of the meetings of
Shareholders.  Such consent shall be treated for all purposes as a vote taken at
a meeting of Shareholders.

Additional Provisions
- ---------------------

     Section 5.  The Bylaws may include further provisions for Shareholders'
     ---------

                  DISTRIBUTIONS, REDEMPTIONS AND REPURCHASES,
                     AND DETERMINATION OF NET ASSET VALUE

Distributions
- -------------

     Section 1.  The Trustees may, but need not, each year distribute to the
     ---------                                                              
Shareholders of each series or class such income and gains, accrued or realized,
as the Trustees may determine, after providing for actual and accrued expenses
and liabilities (including such reserves as the Trustees may establish)
determined in accordance with good accounting practices.  The Trustees shall
have full discretion to determine which items shall be treated as income and
which items as capital and their determination shall be binding upon the
Shareholders.  Distributions of each year's income of each series, if any be
made, may be made in one or more payments, which shall be in Shares, in cash or
otherwise and on a date or dates and as of a record date or dates determined by
the Trustees.  At any time and from time to time in their discretion, the
Trustees may 

                                     -12-
<PAGE>
 
distribute to the Shareholders of any one or more series or classes as of a
record date or dates determined by the Trustees, in Shares, in cash or
otherwise, all or part of any gains realized on the sale or disposition of
property of the series or otherwise, or all or part of any other principal of
the Trust attributable to the series. In the case of any series not divided into
two or more classes of Shares, each distribution pursuant to this Section 1
shall be made ratably according to the number of Shares of the series held by
the several Shareholders on the applicable record date thereof, provided that no
distribution need be made on Shares purchased pursuant to orders received, or
for which payment is made, after such time or times as the Trustees may
determine. In the case of any series divided into two or more classes, each
distribution pursuant to this Section 1 may be made in whole or in such parts as
the Trustees may determine to the Shareholders of any one or more classes, and
the distribution to the Shareholders of any class shall be made ratably
according to the number of Shares of the class (but need not be made ratably
according to the number of Shares of the series, considered without regard to
class) held by the several Shareholders on the record date thereof, provided
that no distribution need be made on Shares purchased pursuant to orders
received, or for which payment is made, after such time or times as the Trustees
may determine. Any such distribution paid in Shares will be paid at the net
asset value thereof as determined in accordance with Section 7 of this Article
VI.

Redemptions and Repurchases
- ---------------------------

     Section 2.  Any holder of Shares of the Trust may by presentation of a
     ---------                                                             
written request, together with his or her certificates, if any, for such Shares,
in proper form for transfer, at the office of the Trust or at a principal office
of a transfer agent appointed by the Trust, redeem his or her Shares for the net
asset value thereof determined and computed in accordance with the provisions of
this Section 2 and the provisions of Section 7 of this Article VI.

     Upon receipt by the Trust or its transfer agent of such written request for
redemption of Shares, such Shares shall be redeemed at the net asset value per
share of the appropriate series or class next determined after such Shares are
tendered in proper order for transfer to the Trust or determined as of such
other time fixed by the Trustees as may be permitted or required by the 1940
Act, provided that no such tender shall be required in the case of Shares for
which a certificate or certificates have not been issued, and in such case such
Shares shall be redeemed at the net asset value per share of the appropriate
series or class next determined after such request has been received in proper
form or determined at such other time fixed by the Trustees as may be permitted
or required by the 1940 Act.

                                     -13-
<PAGE>
 
     The obligation of the Trust to redeem its Shares of each series or class as
set forth above in this Section 2 shall be subject to the conditions that during
any time of emergency, as hereinafter defined, such obligation may be suspended
by the Trust by or under authority of the Trustees for such period or periods
during such time of emergency as shall be determined by or under authority of
the Trustees.  If there is such a suspension, any Shareholder may withdraw any
demand for redemption and any tender of Shares which has been received by the
Trust during any such period and any tender of Shares, the applicable net asset
value of which would but for such suspension be calculated as of a time during
such period.  Upon such withdrawal, the Trust shall return to the Shareholder
the certificates therefor, if any.  For the purposes of any such suspension,
"time of emergency" shall mean, either with respect to all Shares or any series
or class of Shares, any period during which:

          a.  the New York Stock Exchange is closed other than for customary
     weekend and holiday closings; or

          b.  the Trustees or authorized officers of the Trust shall have
     determined, in compliance with any applicable rules and regulations of the
     Securities and Exchange Commission, either that trading on the New York
     Stock Exchange is restricted, or that an emergency exists as a result of
     which (i) disposal by the Trust of securities owned by it is not reasonably
     practicable or (ii) it is not reasonably practicable for the Trust fairly
     to determine the current value of its net assets; or

          c.  the suspension or postponement of such obligations is permitted by
     order of the Securities and Exchange Commission.

     The Trust may also purchase, repurchase or redeem Shares in accordance with
such other methods, upon such other terms and subject to such other conditions
as the Trustees may from time to time authorize at a price not exceeding the net
asset value of such Shares in effect when the purchase or repurchase or any
contract to purchase or repurchase is made.

Payment in Kind
- ---------------

     Section 3.  Subject to any generally applicable limitation imposed by the
     ---------                                                                
Trustees, any payment on redemption of Shares may, if authorized by the
Trustees, be made wholly or partly in kind, instead of in cash.  Such payment in
kind shall be made by distributing securities or other property constituting, in
the opinion of the Trustees, a fair representation of the various types of
securities and other property then held by the series of Shares being redeemed
(but not necessarily involving a portion of 

                                     -14-
<PAGE>
 
each of the series' holdings) and taken at their value used in determining the
net asset value of the Shares in respect of which payment is made.

Redemptions at the Option of the Trust
- --------------------------------------

     Section 4.  The Trust shall have the right at its option and at any time to
     ---------                                                                  
redeem Shares of any Shareholder at the net asset value thereof as determined in
accordance with Section 7 of this Article VI:  (i) if at such time such
Shareholder owns fewer Shares than, or Shares having an aggregate net asset
value of less than, an amount determined from time to time by the Trustees; or
(ii) to the extent that such Shareholder owns Shares of a particular series of
Shares equal to or in excess of a percentage of the outstanding Shares of that
series (determined without regard to class) determined from time to time by the
Trustees; or (iii) to the extent that such Shareholder owns Shares of the Trust
representing a percentage equal to or in excess of such percentage of the
aggregate number of outstanding Shares of the Trust or the aggregate net asset
value of the Trust determined from time to time by the Trustees.

Dividends, Distributions, Redemptions and Repurchases
- -----------------------------------------------------

     Section 5.  No dividend or distribution (including, without limitation, any
     ---------                                                                  
distribution paid upon termination of the Trust or of any series) with respect
to, nor any redemption or repurchase of, the Shares of any series (or of any
class) shall be effected by the Trust other than from the assets of such series
(or of the series of which such class is a part).

Additional Provisions Relating to Redemptions and Repurchases
- -------------------------------------------------------------

     Section 6.  The completion of redemption of Shares shall constitute a full
     ---------                                                                 
discharge of the Trust and the Trustees with respect to such Shares, and the
Trustees may require that any certificate or certificates issued by the Trust to
evidence the ownership of such Shares shall be surrendered to the Trustees for
cancellation or notation.

Determination of Net Asset Value
- --------------------------------

     Section 7.  The term "net asset value" of the Shares of each series or
     ---------                                                             
class shall mean: (i) the value of all the assets of such series or class; (ii)
less the total liabilities of such series or class; (iii) divided by the number
of Shares of such series or class outstanding, in each case at the time of each
determination.  The "number of Shares of such series or class outstanding" for
the purposes of such computation shall be exclusive of any Shares of such series
or class to be redeemed and not then redeemed as to which the redemption price
has been 

                                     -15-
<PAGE>
 
determined, but shall include Shares of such series or class presented for
repurchase and not then repurchased and Shares of such series or class to be
redeemed and not then redeemed as to which the redemption price has not been
determined and Shares of such series or class the sale of which has been
confirmed. Any fractions involved in the computation of net asset value per
share shall be adjusted to the nearer cent unless the Trustees shall determine
to adjust such fractions to a fraction of a cent.

     The Trustees, or any officer or officers or agent of this Trust designated
for the purpose by the Trustees, shall determine the net asset value of the
Shares of each series or class, and the Trustees shall fix the times as of which
the net asset value of the Shares of each series or class shall be determined
and shall fix the periods during which any such net asset value shall be
effective as to sales, redemptions and repurchases of, and other transactions
in, the Shares of such series or class, except as such times and periods for any
such transaction may be fixed by other provisions of this Declaration of Trust
or by the Bylaws.

     In valuing the portfolio investments of any series or class for
determination of net asset value per share of such series or class:

     (a)  Each investment for which market quotations are readily available
          shall be valued at current market value determined by methods
          specified by the Board of Trustees;

     (b)  Each other investment, including any investment within (a) for which
          the specified price does not appear to represent a dependable
          quotation for such investment as of the time of valuation, shall be
          valued at a fair value as determined in good faith by the Trustees;

     (c)  Any cash on hand shall be valued at the face amount thereof;

     (d)  Any cash on deposit, accounts receivable, and cash dividends and
          interest declared or accrued and not yet received, any prepaid
          expenses, and any other current asset shall be valued at the face
          amount thereof, unless the Trustees shall determine that any such item
          is not worth its face amount, in which case such asset shall be valued
          at a fair value determined in good faith by the Trustees; and

     (e)  Any other asset shall be valued at a fair value determined in good
          faith by the Trustees.

                                     -16-
<PAGE>
 
Notwithstanding the foregoing, short-term debt obligations, commercial paper and
repurchase agreements may be, but need not be, valued on the basis of quoted
yields for securities of comparable maturity, quality and type, or on the basis
of amortized cost.

     Liabilities of any series or class for accounts payable for investments
purchased and for Shares tendered for redemption and not then redeemed as to
which the redemption price has been determined shall be stated at the amounts
payable therefor.  In determining the net asset value of any series or class,
the person or persons making such determination on behalf of the Trust may
include in liabilities such reserves, estimated accrued expenses and
contingencies as such person or persons may in its, his or their best judgment
deem fair and reasonable under the circumstances.  Any income dividends and
gains distributions payable by the Trust shall be deducted as of such time or
times on the record date therefor as the Trustees shall determine.

     The manner of determining the net assets of any series or class or of
determining the net asset value of the Shares of any series or class may from
time to time be altered as necessary or desirable in the judgment of the
Trustees to conform to any other method prescribed or permitted by any
applicable law or regulation.

     Determinations under this Section 7 made in good faith and in accordance
with the provisions of the 1940 Act shall be binding on all parties concerned.

                                  ARTICLE VII

                          COMPENSATION AND LIMITATION
                            OF LIABILITY OF TRUSTEES

Compensation
- ------------

     Section 1.  The Trustees as such shall be entitled to reasonable
     ---------                                                       
compensation from the Trust; they may fix the amount of their compensation.
Nothing herein shall in any way prevent the employment of any Trustee for
advisory, management, legal, accounting, investment banking or other services
and payment for the same by the Trust.

Limitation of Liability
- -----------------------

     Section 2.  The Trustees shall not be responsible or liable in any event
     ---------                                                               
for any neglect or wrongdoing of any officer, agent, employee, adviser or
principal underwriter of the Trust, nor shall any Trustee be responsible for the
act or omission of any other Trustee, but nothing herein contained shall protect
any Trustee against any liability to which he or she would otherwise 

                                     -17-
<PAGE>
 
be subject by reason of wilful misfeasance, bad faith, gross negligence or
reckless disregard of the duties involved in the conduct of his or her office.

     Every note, bond, contract, instrument, certificate, writing, Share or
undertaking and every other act or thing whatsoever executed or done by or on
behalf of the Trust or the Trustees or any of them in connection with the Trust
shall be conclusively deemed to have been executed or done only in or with
respect to their or his or her capacity as Trustees or Trustee, and such
Trustees or Trustee shall not be personally liable thereon.

                                 ARTICLE VIII

                                INDEMNIFICATION

Trustees, Officers, etc.
- ------------------------

     Section 1.  The Trust shall indemnify each person who is or has been a
     ---------                                                             
Trustee or officer (including persons who serve at the Trust's request as
directors, officers or trustees of another organization in which the Trust has
any interest as a shareholder, creditor or otherwise) (hereinafter referred to
as a "Covered Person") against all liabilities and expenses, including but not
limited to amounts paid in satisfaction of judgments, in compromise or as fines
and penalties, and counsel fees and expenses reasonably incurred by any Covered
Person in connection with the defense or disposition of any action, suit or
other proceeding, whether civil, criminal, administrative or investigative, and
any appeal therefrom, before any court or administrative or legislative body, in
which such Covered Person may be or may have been involved as a party or
otherwise or with which such person may be or may have been threatened, while in
office or thereafter, by reason of being or having been such a Covered Person,
except that no Covered Person shall be indemnified against any liability to the
Trust or its Shareholders to which such Covered Person would otherwise be
subject by reason of wilful misfeasance, bad faith, gross negligence or reckless
disregard of the duties involved in the conduct of such Covered Person's office.

     Expenses, including counsel fees and expenses so incurred by any such
Covered Person (but excluding amounts paid in satisfaction of judgments, in
compromise or as fines or penalties), may be paid from time to time by the Trust
in advance of the final disposition of any such action, suit or proceeding upon
receipt of an undertaking by or on behalf of such Covered Person to repay
amounts so paid to the Trust if it is ultimately determined that indemnification
of such expenses is not authorized under this Article, provided that (a) such
                                                       -------- ----         
Covered Person shall provide security for his undertaking, (b) the Trust 

                                     -18-
<PAGE>
 
shall be insured against losses arising by reason of such Covered Person's
failure to fulfill his undertaking or (c) a majority of the Trustees who are
disinterested persons and who are not Interested Persons (provided that a
majority of such Trustees then in office act on the matter), or independent
legal counsel in a written opinion, shall determine, based on a review of
readily available facts (but not a full trial-type inquiry), that there is
reason to believe such Covered Person ultimately will be entitled to
indemnification.

Compromise Payment
- ------------------

     Section 2.  As to any matter disposed of (whether by a compromise payment,
     ---------                                                                 
pursuant to a consent decree or otherwise) without an adjudication in a decision
on the merits by a court, or by any other body before which the proceeding was
brought, that such Covered Person is liable to the Trust or its Shareholders by
reason of wilful misfeasance, bad faith, gross negligence or reckless disregard
of the duties involved in the conduct of such Covered Person's office,
indemnification shall be provided if (a) approved as in the best interest of the
Trust, after notice that it involves such indemnification, by at least a
majority of the Trustees who are disinterested persons and are not Interested
Persons (provided that a majority of such Trustees then in office act on the
matter), upon a determination, based upon a review of readily available facts
(but not a full trial-type inquiry) that such Covered Person is not liable to
the Trust or its Shareholders by reason of wilful misfeasance, bad faith, gross
negligence or reckless disregard of the duties involved in the conduct of such
Covered Person's office, or (b) there has been obtained an opinion in writing of
independent legal counsel, based upon a review of readily available facts (but
not a full-trial type inquiry) to the effect that such indemnification would not
protect such Covered Person against any liability to the Trust to which such
Covered Person would otherwise be subject by reason of wilful misfeasance, bad
faith, gross negligence or reckless disregard of the duties involved in the
conduct of his office.

     Any approval pursuant to this Section shall not prevent the recovery from
any Covered Person of any amount paid to such Covered Person in accordance with
this Section as indemnification if such Covered Person is subsequently
adjudicated by a court of competent jurisdiction to have been liable to the
Trust or its Shareholders by reason of wilful misfeasance, bad faith, gross
negligence or reckless disregard of the duties involved in the conduct of such
Covered Person's office.

Indemnification Not Exclusive; Definitions
- ------------------------------------------

     Section 3.  The right of indemnification hereby provided shall not be
     ---------                                                            
exclusive of or affect any other rights to which any such Covered Person may be
entitled.  As used in this Article VIII, the term "Covered Person" shall include
such person's heirs, executors and administrators, and a "disinterested person"
is a person against whom none of the actions, suits or other proceedings in
question or another action, suit or other proceeding on the same or similar
grounds is then or has been pending.  Nothing contained in this article shall
affect any rights to indemnification to which personnel of the Trust, other than
Trustees and officers, and other persons may be entitled by contract or
otherwise under law, nor the power of the Trust to purchase and maintain
liability insurance on behalf of such persons.

Shareholders
- ------------

     Section 4.  In case any Shareholder or former Shareholder shall be held to
     ---------                                                                 
be personally liable solely by reason of his or her being or having been a
Shareholder and not because of his or her acts or omissions or for some other
reason, the Shareholder or former Shareholder (or his or her heirs, executors,
administrators or other legal representatives or, in the case of a corporation
or other entity, its corporate or other general successor) shall be entitled to
be held harmless from and indemnified against all loss and expense arising from
such liability, but only out of the assets of the particular series of Shares of
which he or she is or was a Shareholder.

                                   ARTICLE IX

                                 MISCELLANEOUS

Trustees, Shareholders, etc. Not Personally Liable; Notice
- ----------------------------------------------------------

     Section 1.  All persons extending credit to, contracting with or having any
     ---------                                                                  
claim against the Trust or a particular series of Shares shall look only to the
assets of the Trust or the assets of that particular series of Shares for
payment under such credit, contract or claim; and neither the Shareholders nor
the Trustees, nor any of the Trust's officers, employees or agents, whether
past, present or future, shall be personally liable therefor.  Nothing in this
Declaration of Trust shall protect any Trustee against any liability to which
such Trustee would otherwise be subject by reason of wilful misfeasance, bad
faith, gross negligence or reckless disregard of the duties involved in the
conduct of the office of Trustee.

     Every note, bond, contract, instrument, writing, certificate or undertaking
made or issued by the Trustees or by any officers 

                                     -20-
<PAGE>
 
or officer shall give notice that this Declaration of Trust is on file with the
Secretary of State of The Commonwealth of Massachusetts and shall recite that
the same was executed or made by or on behalf of the Trust or by them as
Trustees or Trustee or as officers or officer and not individually and that the
obligations of such instrument are not binding upon any of them or the
Shareholders individually but are binding only upon the assets and property of
the Trust, and may contain such further recital as he or she or they may deem
appropriate, but the omission thereof shall not operate to bind any Trustees or
Trustee or officers or officer or Shareholders or Shareholder individually.

Trustee's Good Faith Action, Expert Advice, No Bond or Surety
- -------------------------------------------------------------

     Section 2.  The exercise by the Trustees of their powers and discretions
     ---------                                                               
hereunder shall be binding upon everyone interested.  A Trustee shall be liable
for his or her own wilful misfeasance, bad faith, gross negligence or reckless
disregard of the duties involved in the conduct of the office of Trustee, and
for nothing else, and shall not be liable for errors of judgment or mistakes of
fact or law.  The Trustees may take advice of counsel or other experts with
respect to the meaning and operation of this Declaration of Trust, and shall be
under no liability for any act or omission in accordance with such advice or for
failing to follow such advice.  The Trustees shall not be required to give any
bond as such, nor any surety if a bond is required.

Liability of Third Persons Dealing with Trustees
- ------------------------------------------------

     Section 3.  No person dealing with the Trustees shall be bound to make any
     ---------                                                                 
inquiry concerning the validity of any transaction made or to be made by the
Trustees or to see to the application of any payments made or property
transferred to the Trust or upon its order.

Duration and Termination of Trust
- ---------------------------------

     Section 4.  Unless terminated as provided herein, the Trust shall continue
     ---------                                                                 
without limitation of time.  The Trust may be terminated at any time by vote of
the holders of a majority of the votes represented by outstanding Shares of each
series entitled to vote or by the Trustees by written notice to the
Shareholders.  Any series of Shares may be terminated at any time by vote of the
holders of a majority of the votes represented by outstanding Shares of such
series entitled to vote or by the Trustees by written notice to the Shareholders
of such series.

     Upon termination of the Trust or of any one or more series of Shares, after
paying or otherwise providing for all charges, taxes, expenses and liabilities,
whether due or accrued or anticipated as may be determined by the Trustees, the
Trust shall 

                                     -21-
<PAGE>
 
in accordance with such procedures as the Trustees consider appropriate reduce
the remaining assets to distributable form in cash or shares or other
securities, or any combination thereof, and distribute the proceeds to the
Shareholders of the series involved, ratably according to the number of Shares
of such series held by the several Shareholders of such series on the date of
termination, except to the extent otherwise required or permitted by the
preferences and special or relative rights and privileges of any classes of
Shares of that series, provided that any distribution to the Shareholders of a
particular class of Shares shall be made to such Shareholders pro rata in
proportion to the number of Shares of such class held by each of them.

Filing of Copies, References, Headings
- --------------------------------------

     Section 5.  The original or a copy of this instrument and of each amendment
     ---------                                                                  
hereto shall be kept at the office of the Trust where it may be inspected by any
Shareholder.  A copy of this instrument and of each amendment hereto shall be
filed by the Trust with the Secretary of State of The Commonwealth of
Massachusetts and with the Clerk of the City of Springfield, as well as any
other governmental office where such filing may from time to time be required.
Anyone dealing with the Trust may rely on a certificate by an officer of the

2.1  Shareholder Meetings.  A meeting of the shareholders of the Trust or of any
     ---------------------                                                      
one or more series or classes of shares may be called at any time by the
Trustees, by the chairman, the president or, if the Trustees, the chairman and
the president shall fail to call any meeting of shareholders for a period of 30
days after written application of one or more shareholders who hold shares

outstanding shares of the Trust, if shareholders of all series are required
under the Declaration of Trust to vote in the aggregate and not by individual
series at such meeting, or shares representing at least ten percent of all the
votes represented by any series or class, if shareholders of such series or
class are entitled under the Declaration of Trust to vote by individual series
or class at such meeting, then such shareholders may call such meeting.  Each
call of a meeting shall state the place, date, hour and purposes of the meeting.

2.2  Place of Meetings.  All meetings of the shareholders shall be held at the

assistant secretary or by an officer designated by the Trustees.  If the meeting
is a meeting of the shareholders of one or more series or classes of shares, but
not a meeting of all shareholders of the Trust, then only the shareholders of
such one or more series or classes shall be entitled to notice of and to vote at
the meeting.  No notice of any meeting of shareholders need be given to a
shareholder if a written waiver of notice, executed before or after the meeting
by such shareholder or his or her attorney thereunto duly authorized, is filed

responsible to record the proceedings of the meeting, before being voted.
Unless otherwise specifically limited by their terms, such proxies shall entitle
the holders thereof to vote at any adjournment of such meeting but shall not be
valid after the final adjournment of such meeting.  The placing of a
shareholder's name on a proxy pursuant to telephonic or electronically
transmitted instructions obtained pursuant to procedures reasonably designed to
verify that such instructions have been authorized by such shareholder shall
constitute execution of such proxy by or on behalf of such shareholder.

                    Section 5.   Resignations and Removals

Any Trustee, officer or advisory board member may resign at any time by
delivering his or her resignation in writing to the president, the treasurer or
the secretary or to a meeting of the Trustees.  The Trustees may remove any
officer elected by them with or without cause by the vote of a majority of the

agreement with the Trust, no Trustee, officer, or advisory board member
resigning, and no officer or advisory board member removed, shall have any right

or any right to damages on account of such removal.


                            Section 6.   Vacancies
                            ----------------------

<PAGE>
 
                                      -6-

Section 7.3, each shareholder shall be entitled to a certificate stating
the number of shares owned by him or her, in such form as shall be prescribed
from time to time by the Trustees. Such certificate shall be signed by the
chairman, the president or a vice president and by the treasurer or an assistant
treasurer. Such signatures may be facsimiles if the certificate is signed by a
transfer agent or by a registrar, other than a Trustee, officer or employee of
the Trust. In case any officer who has signed or whose facsimile signature has
been placed on such certificate shall have ceased to be such officer before such
certificate is issued, it may be issued by the Trust with the same effect as if
he or she were such officer at the time of its issue.

          In lieu of issuing certificates for shares, the Trustees or the
transfer agent may either issue receipts therefor or keep accounts upon the
books of the Trust for the record holders of such shares, who shall in either
case be deemed, for all purposes hereunder, to be the holders of certificates
for such shares as if they had accepted such certificates and shall be held to
have expressly assented and agreed to the terms hereof.

7.2  Loss of Certificates.  In the case of the alleged loss or destruction or
     ---------------------

place thereof, upon such terms as the Trustees may prescribe.

7.3  Discontinuance of Issuance of Certificates.  The Trustees may at any time
     -------------------------------------------                              
discontinue the issuance of share certificates and may, by written notice to
each shareholder, require the surrender of share certificates to the Trust for
cancellation.  Such surrender and cancellation shall not affect the ownership of
shares in the Trust.


                         Section 8.   Record Date and
                            Closing Transfer Books
                         ----------------------------

The Trustees may fix in advance a time, which shall not be more than 90 days
before the date of any meeting of shareholders or the date for the payment of
any dividend or making of any other distribution to shareholders, as the record
date for determining the shareholders having the right to notice and to vote and
the number of votes entitled to be cast at such meeting and any adjournment
thereof or the right to receive such dividend or distribution, and in such case
only shareholders of record on such record date shall have such right,
notwithstanding any transfer of shares on the books of the Trust after the
record date; or without fixing such record date the Trustees may for any of such
purposes close the transfer books for all or any part of 
<PAGE>
 
                                      -7-

                               Section 9.   Seal
                               -----------------

The seal of the Trust shall, subject to alteration by the Trustees, consist of a
flat-faced circular die with the word "Massachusetts," together with the name of
the Trust and the year of its organization, cut or engraved thereon; but, unless
otherwise required by the Trustees, the seal shall not be necessary to be placed
on, and its absence shall not impair the validity of, any document, instrument
or other paper executed and delivered by or on behalf of the Trust.


                       Section 10.   Execution of Papers
                       ---------------------------------

Except as the Trustees may generally or in particular cases authorize the
execution thereof in some other manner, all deeds, leases, transfers, contracts,

     (c)  as they are modified, from time to time, current versions of the
          documents and policies referred to in Subsections (c), (d), (e) and

     rate .45% of the average daily net asset value of the Fund, determined at
     the close of the New York Stock Exchange on each day that the Exchange is
     open for trading and paid on the last day of each month.

5.   Portfolio Transactions and Brokerage.
     -------------------------------------

     (a)  The Manager 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 Manager 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

          which the broker acts either as principal or as agent.
 
     (c)  The Manager 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 Manager 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.

     under this Management Agreement are not binding upon any Trustee or
     shareholder of the Trust personally, but bind only the Trust and the
     Trust's property.  The Manager represents that it has notice of the
     provisions of the Trust Documents disclaiming shareholder and Trustee
     liability for acts or obligations of the Trust.

     open for trading and paid on the last day of each month.

5.   Portfolio Transactions and Brokerage.
     -------------------------------------

     (a)  The Manager 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 Manager 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 Manager 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 Manager 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.

5.      Portfolio Transactions and Brokerage.
        -------------------------------------

        (a)  The Manager is authorized, in arranging the purchase and sale of

             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

             transactions.

        (b)  The Manager may effect the purchase and sale of securities (which

        delegates any duties hereunder.

9.      Disclaimer of Shareholder Liability.
        ------------------------------------

        The Trust and the Manager understand that the obligations of the Trust
        under this Management Agreement are not binding upon any Trustee or
        shareholder of the Trust personally, but bind only the Trust and the
        Trust's property. The Manager represents that it has notice of the
        provisions of the Trust Documents disclaiming shareholder and Trustee
        liability for acts or obligations of the Trust.

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

        (a)   The Manager shall, subject to the direction and control by the

              and recommendations to the Fund, with respect to the Fund's

              securities; (ii) supervise and monitor continuously the investment
              program of the Fund and the composition of its portfolio and
              determine what securities shall be purchased or sold by the Fund;
              (iii) arrange, subject to the provisions of Section 5 hereof, for
              the purchase of securities and other investments for the Fund and

              obligations under this Management Agreement.

        (e)   The Manager shall cooperate with the Trust by providing the Trust
              with any information in the Manager's possession necessary for

<PAGE>
 
        (a)   cash flow estimates on request;

        (b)   notice of the Fund's "investable funds" by 9:00 a.m. each business
              day;

        (c)   as they are modified, from time to time, current versions of the
              documents and policies referred to in Subsections (c), (d), (e)
              and (f) of Section 1 hereof, above.

4.      Compensation of the Manager.
        ----------------------------

        The Trust agrees to pay the Manager and the Sub-Adviser agrees to accept
        as full compensation for the performance of all functions and duties on
        its part to be performed pursuant to the provisions hereof, a fee at the
        annual rate .45% of the average daily net asset value of the Fund,
        determined at the close of the New York Stock Exchange on each day that
        the Exchange is open for trading and paid on the last day of each month.

5.      Portfolio Transactions and Brokerage.
        -------------------------------------

        (a)   The Manager 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 Manager 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 Manager 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 Manager 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 Management
        Agreement shall remain in effect until June 30, 1995. Thereafter it
        shall continue in effect from year to 

                                       3
<PAGE>
 
        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 Management Agreement
        or "interested persons" (as defined in the Act) of any such party cast
        in person at a meeting called for the purpose of voting on such
        approval, or by the holders of a "majority" (as defined in the Act) of
        the outstanding voting securities of the Fund.

7.      Termination.
        ------------

        This Management Agreement shall terminate automatically upon its
        assignment or in the event upon the termination of the Advisory
        Management Agreement; it may also be terminated: (i) for cause or with
        the consent of the parties and the Trust by the Trust or the Manager at
        any time without penalty upon sixty days' written notice to the other
        party and the Trust; or (ii) by the Trust at any time without penalty
        upon sixty days' written notice to the Trust and the Manager 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.      Investment Sub-Advisory Contracts.
        ----------------------------------

        (a)   Subject to the provisions of the Agreement and Declaration of
              Trust and the 1940 Act, the Manager, at its expense, may, in its
              discretion (subject only to approval by the Trust's Board of
              Trustees and, if necessary, the Trust's shareholders) select and
              contract with an investment sub-adviser (the "Sub-Adviser") for
              the Fund. So long as any Sub-Adviser serves as Sub-Adviser to the
              Fund, it must be a party to a Sub-Investment Advisory Agreement in
              substantially the form attached hereto as Schedule A (the
                                                        ----------     
              "Sub-Adviser Agreement") and will be obligated to:

                    (1) Furnish continuously an investment program as to those
                    assets of the Trust and the Fund as allocated by the
                    Manager;

                    (2) In connection therewith, adhere to such guidelines as
                    may be established by the Manager from time to time to
                    insure compliance with applicable investment objectives,
                    policies and restrictions of the Trust and the Fund; and

                    (3) Place all orders for the purchase and sale of
                    investments of the Fund.

        (b) The Manager will be responsible for payment of all compensation to
        any Sub-Adviser and other persons and entities to which Manager
        delegates any duties hereunder.

9.      Disclaimer of Shareholder Liability.
        ------------------------------------

        The Trust and the Manager understand that the obligations of the Trust
        under this Management Agreement are not binding upon any Trustee or
        shareholder of the Trust personally, but bind only the Trust and the
        Trust's property. The Manager represents that it has notice of the
        provisions of the Trust Documents disclaiming shareholder and Trustee
        liability for acts or obligations of the Trust.

          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

     liability for acts or obligations of the Trust.

          trading any securities for its own account or for the account of
          others for whom it or they may be acting, provided that such

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

3.   Duties of the Trust.
     --------------------

     The Trust shall provide the Manager with the following information about
     the Fund:

                                       2
<PAGE>
 
     (a)  cash flow estimates on request;

     (b)  notice of the Fund's "investable funds" by 9:00 a.m. each business
          day;

     (c)  as they are modified, from time to time, current versions of the
          documents and policies referred to in Subsections (c), (d), (e) and
          (f) of Section 1 hereof, above.

4.   Compensation of the Manager.
     ----------------------------

     The Trust agrees to pay the Manager and the Sub-Adviser agrees to accept as
     full compensation for the performance of all functions and duties on its
     part to be performed pursuant to the provisions hereof, a fee at the annual
     rate .85% of the average daily net asset value of the Fund, determined at
     the close of the New York Stock Exchange on each day that the Exchange is
     open for trading and paid on the last day of each month.

5.   Portfolio Transactions and Brokerage.
     -------------------------------------

     (a)  The Manager 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 Manager 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 Manager 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 Manager 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.

     ---------

     Unless terminated earlier pursuant to Section 7 hereof, this   Management
     Agreement shall remain in effect until June 30, 1995.  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

     securities of the Fund.

     or in the event upon the termination of the Advisory Management Agreement;

     and the Trust by the Trust or the Manager at any time without penalty upon
     sixty days' written notice to the other party and the Trust; or (ii) by the
     Trust at any time without penalty upon sixty days' written notice to the
     Trust and the Manager provided that such termination by the Trust shall be

     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).

          established by the Manager from time to time to insure compliance with
          applicable investment objectives, policies and restrictions of the
          Trust and the Fund; and

          (3)  Place all orders for the purchase and sale of investments of the
          Fund.

     Trust's property.  The Manager represents that it has notice of the
     provisions of the Trust Documents disclaiming shareholder and Trustee
     liability for acts or obligations of the Trust.

         (b)      Provided that none of MassMutual, the Fund or the Trust shall
                  be required to pay any compensation other than as provided by
                  the terms of this Sub-Advisory Agreement and subject to the
                  provisions of Section 5 hereof, the Sub-Adviser may obtain

                  person, firm or corporation to supplement, update or otherwise
                  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

                  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
                  MassMutual with any information in the Sub-Adviser's
                  possession reasonably necessary for supervising the activities

                  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 request.

3. Duties of MassMutual
   --------------------

         MassMutual shall provide the Sub-Adviser with the following information
         about the Fund:

         (a)      cash flow estimates on request;

         (b)      notice of the Fund's "investable funds" by 9:00 a.m. each
                  business day;

         (c)      as they are modified, from time to time, current versions of
                  the documents and policies referred to in Subsections (c),
                  (d), (e) and (f) of Section 1 hereof, above.

4. Compensation of the Sub-Adviser.
   --------------------------------

         MassMutual agrees to pay the Sub-Adviser and the Sub-Adviser agrees to
         accept as full compensation for the performance of all functions and
         duties on its part to be performed pursuant to the provisions hereof, a
         fee at the annual rate .50% of the average daily net asset value of the
         Fund, determined at the close of the New York Stock Exchange on each
         day that the Exchange is open for trading and paid on the last day of
         each week.

5. Portfolio Transactions and Brokerage.
   -------------------------------------

         (a)      The Sub-Adviser is authorized, in arranging the Fund's
                  portfolio transactions, to employ or deal with such members of
                  securities or commodities exchanges, brokers or dealers
                  including "affiliated" broker-dealers (as that term is defined
                  in the Act)(hereinafter "broker'dealers"), 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 as well as to obtain,
                  consistent with the provisions of subparagraph (c) of this
                  paragraph 5, the benefit of such investment information or
                  research as may be of significant assistance to the
                  performance by Sub-Adviser of its investment management
                  functions.

         (b)      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
                  transactions will be judged by Sub-Adviser on the basis of all
                  relevant factors and considerations, including, insofar as

                                       3
<PAGE>
 
                  feasible, the execution capabilities required by the
                  transaction(s); 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 and 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.

         (c)      The Sub-Adviser shall have discretion, in the interests of the
                  Fund, to allocate brokerage on the Fund's portfolio
                  transactions to broker-dealers other than affiliated broker-
                  dealers, qualified to obtain best execution of such
                  transactions who provide brokerage and/or research services
                  (as such services are defined in (S)28(e)(3) of the Securities
                  and Exchange Act of 1934) for the Fund and/or any other
                  accounts for which Sub-Adviser and its affiliates exercise
                  "investment discretion" (as that term is defined in 
                  (S)3(a)(35) of the Securities and Exchange Act of 1934) and to
                  cause the Fund to pay such broker-dealers a commission for the
                  effecting a portfolio transaction for the Fund that is in
                  excess of the amount of commission another broker-dealer
                  adequately qualified to effect such transaction would have
                  charged for effecting that transaction, if the Sub-Adviser
                  determines in good faith that such commission is reasonable in
                  relation to the value of the brokerage and/or research
                  services provided by such broker-dealer, viewed in terms of
                  either the particular transaction or the overall
                  responsibilities of Sub-Adviser and its investment advisory
                  affiliates with respect to the accounts as to which they
                  exercise investment discretion. In reaching such
                  determination, Sub-Adviser will not be required to place or
                  attempt to place a specific dollar value on the brokerage
                  and/or research services provided or being provided by such
                  broker-dealer. In demonstrating that such determinations were
                  made in good faith, Sub-Adviser shall be prepared to show all
                  commissions were allocated for the purposes contemplated by
                  this Agreement and that the total commissions paid by the Fund
                  over a representative period selected by the Fund's Trustees
                  were reasonable in relation to the benefits to the Fund.

         (d)      Sub-Adviser shall have no duty or obligation to seek advance
                  competitive bidding for the most favorable commission rate
                  applicable to any particular portfolio transaction or to
                  select any broker-dealer on the basis of its purported or
                  "posted" commission rate but will to the best of its ability,
                  endeavor to be aware of the current level of the charges of
                  eligible broker-dealers and to minimize the expenses incurred
                  by the Fund for effecting its portfolio transactions to the
                  extent consistent with the interests and policies of the Fund
                  as established by the determinations of its Board of Trustees
                  and the provisions of this Paragraph 5.

         (e)      The Fund recognizes that an affiliated broker-dealer (i) may
                  act as its regular broker as long as it is lawful for it to so
                  act; (ii) may be a major recipient of brokerage commissions
                  paid by the Fund; and (iii) may effect portfolio transactions
                  for the Fund only if the commissions, fees or other
                  renumerations received or to be received by it are determined
                  in accordance with the procedures contemplated by a ny rule,
                  regulation or order adopted under the Act for determining the
                  permissible level of such commissions.

         (f)      Subject to the foregoing provisions of this Paragraph 5,
                  Sub-Adviser may also 

                                       4
<PAGE>
 
                  consider sales of Fund shares and shares of other investment
                  companies managed by Sub-Adviser or its affiliates as a factor
                  in the selection of broker-dealers for the Fund's portfolio
                  transactions.

of the Treasury Department issued thereunder, and will execute and deliver all
such certificates in connection therewith as may be required by such laws or

(ii) the making of an entry on the records of the Bank (or its agent) to reflect

Account; and

                    (ii) The making of an entry on the records of the Bank (or
its agent) to reflect such transfer and payment for the account of the Trust.
Copies of all advice from the Book-Entry System of transfers of securities for
the account of the Trust shall identify the Trust, be maintained for the Trust
by the Bank and shall be provided to the Trust at its request. The Bank shall
send the Trust a confirmation, as defined by Rule 17f-4 of the 1940 Act, of any
transfers to or from the account of the Trust;

              (d) The Bank will promptly provide the Trust with any report

to the Trust resulting from use of the Book-Entry System by reason of any
negligence, willful misfeasance or bad faith of the Bank or any of its agents or
of any of its or their employees or from any reckless disregard by the Bank or
any such agent of its duty to use its best efforts to enforce such rights as it
may have against the Book-Entry System; at the election of the Trust, it shall
be entitled to be subrogated for the Bank in any claim against the Book-Entry
System or any other person which the Bank or its agent may have as a consequence
of any such loss or damage if and to the extent that the Trust has not been made
whole for any loss or damage;

release, lend, deliver and otherwise deal with Portfolio Securities including
stock dividends, rights and other items of like nature, and to receive and remit

take all steps necessary and proper in connection with the collection thereof;

futures, puts and calls traded on commodities exchanges, any Futures Commission
Merchant account and the Segregated Account shall be limited as set forth in

without any such payment. In the event that any such pledged Portfolio
Securities are held by the Bank, they will be so held for the account of the
lender, and after notice to the Trust from the lender in accordance with the
normal procedures of the lender, that an event of deficiency or default on the
loan has occurred, the Bank may deliver such pledged Portfolio Securities to or
for the account of the lender;

collect any funds which may to its knowledge become collectible arising from
Portfolio Securities, including dividends, interest and other income, and to

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

hereunder and shall be responsible for the acts and omissions of such agents as
if performed by the Bank hereunder.

       (b)  Subcustodians.


                (i)  Upon receipt of Proper Instructions, the Bank may employ
subcustodians, provided that any such subcustodian meets at least the minimum
qualifications required by Section 17(f)(1) of the 1940 Act to act as a
custodian of the Trust's assets with respect to property of the Trust held in
the United States.


                (ii)  Assets held by subcustodians in countries other than the

             ----------                                       
coverages adequate for the nature of its operations, including directors and
officers, errors and omissions, and fidelity bond insurance coverages. The Bank
shall have the Trust named as 
<PAGE>
 
                                      17

a Certificate Holder on each of these coverages, and provide MassMutual with
Certificates of Insurance at each policy renewal. The Certificates shall provide
that MassMutual receive a minimum of twenty (20) days' notice of cancellation,
non-renewal, or material change of policy coverages. The Bank shall provide
MassMutual with copies of its insurance policies, upon request. If at any time,
due to a material adverse change in policy coverages, MassMutual reasonably
believes that such coverages are insufficient in any material respect, or if any
policy is placed with an insurer with an A.M. Best rating of less than A 12, the
Bank shall take reasonable steps to satisfy MassMutual's concerns.

       12.4. Fees and Expenses of Bank. The Trust will pay or reimburse the Bank
             -------------------------                                          
from time to time for any transfer taxes payable upon transfer of Portfolio
Securities made hereunder, and for all necessary proper disbursements, expenses
and charges made or incurred by the Bank in the performance of this Agreement
(including any duties listed on any Schedule hereto, if any) including any
indemnities for any loss, liabilities or expense to the Bank as provided above.
For the services rendered by the Bank hereunder, the Trust will pay to the Bank
such compensation or fees at such rate and at such times as shall be agreed upon
in writing by the parties from time to time. The Bank will also be entitled to
reimbursement by the Trust for all reasonable expenses incurred in conjunction
with termination of this Agreement by the Trust.

       12.5 Advances by Bank. The Bank may, in its sole discretion, advance 
            -----------------   
funds on behalf of the Trust to make any payment permitted by this Agreement
upon receipt of any proper authorization required by this Agreement for such
payments by the Trust. Should such a payment or payments, with advanced funds,
result in an overdraft (due to insufficiencies of the Trust's account with the
Bank, or for any other reason other than as a result of a mistake by the Bank),
such overdraft or related indebtedness, shall be deemed to be a loan made by the
Bank to the Trust payable on demand and bearing interest at the current rate
charged by the Bank for such loans unless the Trust shall provide the Bank with
agreed upon compensating balances. The Trust agrees that the Bank shall have a
continuing lien and security interest to the extent of any overdraft or
indebtedness, in and to any property at any time held by it for the Trust's
benefit or in which the Trust has an interest and which is then in the Bank's
possession or control (or in the possession or control of any third party acting
on the Bank's behalf). The Trust authorizes the Bank, in its sole discretion, at
any time to charge any overdraft or indebtedness, together with interest due
thereon against any balance of account standing to the credit of the Trust on
the Bank's books.

     13. Termination.
         ----------- 

       13.1 This Agreement may be terminated at any time without penalty upon
ninety (90) days' written notice delivered by either party to the other by means
of registered mail, and upon the expiration of such ninety (90) days this
Agreement will terminate; provided, however, that the effective date of such
termination may be postponed to a date not more than thirty (30) additional days
from the date of delivery of such notice:

       (a) by the Bank in order to prepare for the transfer by the Bank of all
of the assets of the Trust held hereunder, provided that the Bank has not acted
in a manner that would constitute negligence, gross negligence, willful
misconduct, bad faith or fraud, and
<PAGE>
 
                                      18

       (b) by the Trust in order to give the Trust an opportunity to make
suitable arrangements for a successor custodian, provided however, that the
Trust is not in breach of a material term or condition of this Agreement.

At any time after the termination of this Agreement, the Trust will, at its
request, have access to the records of the Bank relating to the performance of
its duties as custodian.  This Agreement shall also terminate upon the delivery
of the Trust's Portfolio Securities, the disbursement of cash, and the payment
of fees and expenses of the Bank in the case of certain transactions described
in Section 8 hereof.

       13.2 In the event of the termination of this Agreement, the Bank will
immediately upon receipt or transmittal, as the case may be, of notice of
termination, commence and prosecute diligently to completion the transfer of all
cash and the delivery of all Portfolio Securities duly endorsed and all records
maintained under Section 11 hereof to the successor custodian when appointed by
the Trust. The obligation of the Bank to deliver and transfer over the assets of
the Trust held by it directly to such successor custodian will commence as soon
as such successor is appointed and will continue until completed as aforesaid.

       13.3 If the Trust does not select a successor custodian within ninety
(90) days from the date of delivery of notice of termination the Bank may,
subject to the provisions of subsection 14.3, deliver the Portfolio Securities
and cash of the Trust held by the Bank to a bank or trust company of its own
selection which meets the requirements of Section 17(f)(1) of the 1940 Act and
has a reported capital, surplus and undivided profits aggregating not less than
$2,000,000, to be held as the property of the Trust under terms similar to those
on which they were held by the Bank, whereupon such bank or trust company so
selected by the Bank will become the successor custodian of such assets of the
Trust with the same effect as though selected by the Board.

       13.4 Prior to the expiration of ninety (90) days after notice of
termination has been given, the Trust may furnish the Bank with an order of the
Trust advising that a successor custodian cannot be found willing and able to
act upon reasonable and customary terms and that there has been submitted to the
shareholders of the Trust the question of whether the Trust will be liquidated
or will function without a custodian for the assets of the Trust held by the
Bank. In that event the Bank will deliver the Portfolio Securities and cash of
the Trust held by it, subject as aforesaid, in accordance with one of such
alternatives which may be approved by the requisite vote of shareholders, upon
receipt by the Bank of a copy of the minutes of the meeting of shareholders at
which action was taken, certified by the Trust's Secretary and an opinion of
counsel to the Trust in form and content satisfactory to the Bank.

       13.5  Notwithstanding the above, the Trust may terminate this Agreement
without penalty at anytime after the Bank receives a rating of four and one-half
(4.5), on a scale of 1-5 with one (1)  being the best rating and five (5) the
worst, by Cates Consulting Analysts, a Division of the Ferguson Company.

     14. Confidentiality.  Both parties hereto agree than any non-public
         ---------------                                                
information, including trade secrets,  obtained hereunder concerning the other
party is confidential and 
<PAGE>
 
                                      19

may not be disclosed to any other person, firm, corporation, association, or
other entity, without the prior written consent of the other party, except as
may be required by applicable law or at the request of a governmental agency.
The parties further agree, that without waiving any other legal or equitable
rights or remedies, that a breach of this provision would irreparably damage the
other party and accordingly agree that each of them is entitled, without bond or
other security, to an injunction or injunctions to prevent breaches of this
provision.

event shall the Manager or the Trust be liable to the other, or to any third
party, for special, punitive or consequential damages arising, directly or

party of the possibility of such damages.

E.  Acts of God.  In the event either party is unable to perform its obligations
under the terms of this Agreement because of acts of God, interruption of
electrical power or other utilities, equipment or transmission failure or damage
reasonably beyond its control, or other causes reasonably beyond its control,
such party shall not be liable to the other for any damages resulting from such
failure to perform or otherwise from such causes.  The Manager, the Trust and

taken by it in reliance upon any document, certificate or instrument which it

person or persons.

D.  Damages.   Notwithstanding anything in this Agreement to the contrary, in no
event shall the Manager or the Trust be liable to the other, or to any third
party, for special, punitive or consequential damages arising, directly or
indirectly from this Agreement, even if said party has been advised by the other
party of the possibility of such damages.

E.  Acts of God. In the event either party is unable to perform its obligations
under the terms of this Agreement because of acts of God, interruption of
electrical power or other utilities, equipment or transmission failure or damage
reasonably beyond its control, or other causes reasonably beyond its control,
such party shall not be liable to the other for any damages resulting from such
failure to perform or otherwise from such causes.  The Manager, the Trust and
MassMutual shall notify each other as soon as reasonably possible following the

          by Fund and by Class which are authorized, based upon data provided to
          it by the Trust, and issued and outstanding. The Bank shall also
          provide the Trust on a regular basis with the total number of Shares
          which are authorized and issued and outstanding and shall have no
          obligation, when recording the issuance of Shares, to monitor the
          issuance of such Shares or to 
<PAGE>
 
           take cognizance of any laws relating to the issue or sale of such
           Shares, which functions shall be the sole responsibility of the
           Trust.

      (b)  In addition to and not in lieu of the services set forth in the above

                        ARTICLE 2: Sale of Trust Shares
                        -------------------------------

    2.01  Whenever the Trust shall sell or cause to be sold any Shares of a
Fund, MassMutual shall deliver or cause to be delivered to the Bank a document
or electronic file specifying: (i) the name of the Fund and Class thereof whose
Shares were sold; (ii) the number of Shares sold, trade date, and price; 
(iii) the amount of money to be delivered to the Custodian for the sale of such
Shares and specifically allocated to such Fund; and (iv) in the case of a new
account, a new account application or sufficient information to establish an
account, and (v) the name of the holder.

identified by it as an investment in Shares of one of the Funds and drawn or
endorsed to the Bank as agent for, or identified as being for the account of,
one of the Funds, promptly deposit such check or other payment to the
appropriate account postings necessary to reflect the investment. The Bank will
notify the Trust, or its designate, and the Custodian of all purchases and
related account adjustments.

    2.03  Under procedures established by mutual agreement between MassMutual
and the Bank, the Bank shall credit to the purchaser or his authorized agent's
account, as identified by MassMutual, such Shares, computed to the nearest three
decimal points, as he is entitled to receive, based on the appropriate net asset
value of the Funds' Shares, determined in accordance 
<PAGE>
 
with the prospectus and applicable Federal law or regulation. In issuing Shares
to a purchaser or his authorized agent, the Bank shall be entitled to rely upon
the latest directions, if any, previously received by the Bank from MassMutual
on behalf of the purchaser or his authorized agent concerning the delivery of
such Shares. Unless otherwise agreed upon, the Bank shall have no obligation to
provide confirmations of share transactions.

    2.04  The Bank shall not be required to issue any Shares of the Trust when
it has received a written instruction from MassMutual or the Trust or written
notification from any appropriate Federal or State authority that the sale of
the Shares of the Fund(s) in question has been suspended or discontinued, and
the Bank shall be entitled to rely upon such written instructions or written
notification.

    2.05  Upon the issuance of any Shares of any Fund(s) in accordance with
foregoing provisions of this Section, the Bank shall not be responsible for the
payment of any original issue or other taxes, if any, required to be paid by the
Trust in connection with such issuance.

    2.06  The Bank may establish such additional rules and regulations governing
the transfer or registration of Shares as it may deem advisable and consistent
with such rules and regulations generally adopted by transfer agents (not
inconsistent with this Agreement). Moreover, with the written consent of the
Trust, the Bank may adopt any other rules and regulations.

                          ARTICLE 3: Returned Checks
                          --------------------------

    3.01  In the event that any check or other order for the transfer of money
is returned unpaid for any reason, the Bank will take such steps as the Bank
may, in its discretion, deem appropriate to protect the Trust from financial
loss or as the Trust or its designate may instruct. Provided that the standard
procedures, as agreed upon from time to time, between the Trust and the Bank,
regarding purchases and redemptions of Shares, are adhered to by the Bank, the
Bank shall not be liable for any loss suffered by a Fund as a result of returned
or unpaid purchase or redemption transactions. Legal or other expenses incurred
to collect amounts owed to a Fund as a consequence of returned or unpaid
purchase or redemption transactions shall be an expense of that Fund.

                            ARTICLE 4: Redemptions
                            ----------------------

    4.01  Shares of any Fund may be redeemed in accordance with the procedures

requests transmitted to it by MassMutual in accordance with Trust policies set

each Fund, exchanges between Funds on the records of the Funds maintained by the
Bank, and exchanges between the Trust and any other entity as may be permitted
by the Prospectus of the Trust and in accordance with instructions from
MassMutual. The Bank will, upon an order to transfer Shares by or on behalf of
the registered holder thereof in proper form, credit the same to the transferee
on its books. If Shares are to be exchanged for Shares of another Fund, the Bank
will process such exchange in the same manner as a redemption and sale of
Shares, except that it may in its reasonable discretion waive requirements for
information and documentation.

                      ARTICLE 6: Right to Seek Assurances
                      -----------------------------------

    6.01  The Bank reserves the right to refuse to transfer or redeem Shares
until it is satisfied that the requested transfer or redemption is legally
authorized, and it shall incur no liability for the refusal, in good faith, to
make transfers or redemptions which the Bank, in its reasonable judgment, deems
improper or unauthorized, or until it is satisfied that there is no basis for
any claims adverse to such transfer or redemption. The Bank may, in effecting
transfers, rely upon the provisions of the Uniform Act for the Simplification of
Fiduciary Security Transfers or the Uniform Commercial Code, as the same may be
amended from time to time, which in the opinion of legal counsel for the Trust
protect it in not requiring certain documents in connection with the transfer or
redemption of Shares of any Fund, and the Trust shall indemnify the Bank for any
act done or omitted by it in reliance upon such laws or opinions of counsel of
the Trust.

and authorizing the Bank to rely on oral instructions or a Certificate
specifying the date of the declaration of such dividend or distribution, the
date of payment thereof, the record date as of which Shareholders entitled to

distribution by a Fund, the date of payment thereof, the record date as of which
Shareholders entitled to payment shall be determined, and the amount payable per
share to the Shareholders of record as of the record date and the total amount
payable to the Bank as the Trust's disbursing agent on the payment date.

    7.02  To the extent that dividends are not automatically reinvested, the
Bank, on behalf of the Trust, shall instruct the Custodian to place in a
dividend disbursing account funds equal to the cash amount of any dividend or
distribution to be paid out. The Bank will calculate, prepare and mail checks to
(at the address as it appears on the records of the Bank), or (where
appropriate) credit any dividend or distribution to the account of Fund
Shareholders and maintain and safeguard all underlying records.

    7.03  The Bank will promptly replace lost checks at its discretion and in
conformity with regular business practices.

    7.04  The Bank will maintain all records necessary to reflect the crediting
of dividends or distributions which are reinvested in Shares of the Trust,
including without limitation daily dividends or distributions.

    7.05  The Bank shall not be liable for any improper payments made in
accordance with a resolution of the Trust of the Board of Trustees of the Trust.
<PAGE>

as of the record date until such sufficient cash is provided to the Bank.

distributions such as the payment of dividends and capital gain distributions
and tax withholding with the proper Federal, State and local authorities as are

Act will be preserved for the periods prescribed in Rule 31a-2 under the 1940
Act. Such records may be inspected by MassMutual or the Trust at reasonable
times. The Bank may, at its option at any time, and shall forthwith upon
MassMutual's or the Trust's demand, turn over to MassMutual or 
<PAGE>
 
the Trust and cease to retain in the Bank's files, records and documents created
and maintained by the Bank in performance of its service or for its protection.
At the end of the six-year retention period, such periods and documents will
either be turned over to MassMutual or the Trust, or destroyed in accordance
