                Section I--Overview of New England Zenith Fund
 
 
Organization
   
The Fund is a mutual fund consisting of multiple investment portfolios, the
Series. New England Investment Management, Inc. ("NEIM") (formerly TNE
Advisers, Inc.) is the investment adviser to all the Series except Capital
Growth, which is managed by Capital Growth Management ("CGM"). NEIM has
contracted with subadvisers to make the day-to-day investment decisions for
all Series except Capital Growth. CGM makes the day-to-day investment
decisions for Capital Growth.     
 
Investors
   
Fund shares are offered only to SEPARATE ACCOUNTS established by New England
Life Insurance Company ("New England Financial") and Metropolitan Life
Insurance Company ("Metropolitan Life") or their affiliates (the "Separate
Accounts"). The Fund serves as the investment vehicle for variable life
insurance, variable annuity and group annuity products of New England
Financial and Metropolitan Life or their affiliates. The general public may
not directly purchase Fund shares. The performance information in the
Prospectus does not reflect charges associated with the Separate Accounts or
variable contracts that an investor in the Fund may pay under insurance or
annuity contracts.     
   
Types of Investments     
   
Each Series invests in a variety of securities. Securities generally fall into
two main categories: equity and fixed-income.     
   
 Equity Securities     
   
Equity securities include common stocks, preferred stocks and other
instruments related to common and preferred stocks. Generally, common and
preferred stocks represent ownership interests in a corporation. Stocks often
pay a DIVIDEND.     
   
Investment advisers often characterize stocks as growth stocks or value
stocks. Generally, an investment adviser considers a stock to be a growth
stock if it expects the company's earnings to grow relatively rapidly.
Generally, value stocks are the stocks of companies that an investment adviser
believes are inexpensive relative to other stocks under current market
conditions. A stock may display characteristics of both classifications.
Therefore, it is possible that a stock may be characterized as a growth stock
by some investment professionals and as a value stock by other investment
professionals.     
   
Stocks are also often categorized according to the market capitalization of
the issuer. Market capitalization is calculated by multiplying the total
number of outstanding shares of an issuer by the market price of those shares.
Some mutual funds invest primarily in stocks of issuers with larger
capitalizations, while other mutual funds invest primarily in stocks of
issuers with medium or small capitalizations.     
 
A SEPARATE ACCOUNT is a pool of assets set aside by an insurance company to
fund payments under a specified group of insurance policies or contracts.
   
A DIVIDEND is a payment made by a company to a shareholder that typically is
based on the issuer's performance. A dividend may be paid as cash or
additional securities.     

                                      B-3
<PAGE>
 
   
The MATURITY DATE is the date on which a fixed-income security "matures." This
is the date on which the borrower must pay back the borrowed amount, the
principal.     
   
 Fixed-income Securities     
   
Fixed-income securities represent an obligation of an issuer to repay money
that it has borrowed. Generally, the issuer agrees to pay the investor interest
in return for the use of the money until the MATURITY DATE, as set forth in the
terms of the security. The rate of interest may be fixed or variable.

               Section II--Summary Information about each Series
 
                     Back Bay Advisors Money Market Series
 
Investment Objective
 
The investment objective of the Back Bay Advisors Money Market Series ("Money
Market") is the highest possible level of current income consistent with
preservation of capital.
 
Principal Investment Strategies
   
Back Bay Advisors, Inc. ("Back Bay Advisors") invests Money Market's assets in
a managed portfolio of MONEY MARKET INSTRUMENTS.     
 
Principal Investment Risks
 
AN INVESTMENT IN MONEY MARKET IS NOT INSURED OR GUARANTEED BY THE FEDERAL
DEPOSIT INSURANCE CORPORATION OR ANY OTHER GOVERNMENT AGENCY. ALTHOUGH MONEY
MARKET SEEKS TO PRESERVE THE VALUE OF YOUR INVESTMENT AT $100.00 PER SHARE, IT
IS POSSIBLE TO LOSE MONEY BY INVESTING IN MONEY MARKET.
 
Factors that could harm the investment performance of Money Market include:
 
  . A general decline in fixed-income security markets.
 
  . Poor performance of individual fixed-income securities held by Money
    Market, which may be due to interest rate risk and credit risk.
Investment Performance Record
   
The bar chart below shows the annual total return of Money Market for the last
ten full calendar years. The table following the bar chart compares the average
annual total returns of Money Market to the returns of a relevant broad-based
securities market index. This information helps illustrate the volatility of
Money Market's returns, and does not reflect charges associated with the
Separate Accounts or variable contracts that an investor in the Fund may pay
under insurance or annuity contracts.

                      Back Bay Advisors Bond Income Series
 
Investment Objective
 
The investment objective of the Back Bay Advisors Bond Income Series ("Bond
Income") is a high level of current income consistent with protection of
capital.
 
Principal Investment Strategies
   
Back Bay Advisors, Bond Income's subadviser, invests Bond Income's assets
primarily in fixed-income securities. Back Bay Advisors will invest at least
80% of Bond Income's assets in INVESTMENT GRADE securities, and may invest up
to 10% of Bond Income's assets in obligations of foreign issuers.     
 
Principal Investment Risks
 
Investing in Bond Income involves risks. Bond Income may not perform as well as
other investments, and it is possible for investors to lose money. Factors that
could harm the investment performance of Bond Income include:
 
  . A general decline in U.S. or foreign fixed-income security markets.
 
  . Poor performance of individual fixed-income securities held by Bond
    Income, which may be due to interest rate risk and credit risk.
     
  . The risks associated with investments in foreign securities. Foreign
    securities may be subject to less regulation and additional regional,
    national and currency risks. These risks are discussed more fully in
    Section III.     
 
 
INVESTMENT GRADE: Moody's and Standard & Poor's are rating agencies that assign
a "credit rating" to fixed-income securities and issuers based on the agency's
evaluation of the risk that the issuer will default on its obligations.
Securities or issuers that earn one of the top four ratings from Moody's or
Standard & Poor's are considered "investment grade." In this Prospectus,
unrated securities that, in the subadviser's judgment, are of similar quality
to other securities rated investment grade are also referred to as investment
grade.
 
Fixed-income securities that are below investment grade quality are referred to
as HIGH YIELD DEBT. High yield debt is typically riskier than investment grade
securities.

annual total returns of Bond Income to the returns of a relevant broad-based
securities market index and to returns of a group of other similar mutual funds

with the Separate Accounts or variable contracts that an investor in the Fund

              Salomon Brothers Strategic Bond Opportunities Series
 
Investment Objective
 
The investment objective of the Salomon Brothers Strategic Bond Opportunities
Series ("Strategic Bond") is a high level of total return consistent with
preservation of capital.
 
Principal Investment Strategies
   
Salomon Brothers Asset Management Inc ("SBAM"), Strategic Bond's subadviser,
invests substantially all of Strategic Bond's assets in three classes of fixed-
income securities: (1) U.S. investment grade securities (including U.S.
Government obligations), (2) U.S. and foreign HIGH YIELD DEBT, and (3) foreign
government securities.     
 
Principal Investment Risks
 
Investing in Strategic Bond involves risks. Strategic Bond may not perform as
well as other investments, and it is possible for investors to lose money.
Factors that could harm the investment performance of Strategic Bond include:
 
  . A general decline in U.S. or foreign fixed-income security markets.
 
  . Poor performance of the classes of fixed-income securities held by
    Strategic Bond.
 
  . Poor performance of individual fixed-income securities held by Strategic
    Bond, which may be due to interest rate risk and credit risk.
     
  . The risks associated with investments in foreign securities, which may be
    subject to less regulation and additional regional, national and currency
    risk. These risks are discussed more fully in Section III.     
 
 
INVESTMENT GRADE: MOODY'S and Standard & Poor's are rating agencies that assign
a "credit rating" to fixed-income securities and issuers based on the agency's
evaluation of the risk that the issuer will default on its obligations.
Securities or issuers that earn one of the top four ratings from Moody's or
Standard & Poor's are considered "investment grade." In this Prospectus,
unrated securities that, in the subadviser's judgment, are of similar quality
to other securities rated investment grade are also referred to as investment
grade.
 
Fixed-income securities that are below investment grade quality are referred to
as HIGH YIELD DEBT. High yield debt is typically riskier than investment grade
securities.

full calendar year since the Series began operations. The table following the
bar chart compares the average annual total returns of Strategic Bond to the
returns of a relevant broad-based securities market index and to returns of a

                    Salomon Brothers U.S. Government Series
 
Investment Objective
 
The investment objective of the Salomon Brothers U.S. Government Series (the
"U.S. Government Series") is a high level of current income consistent with
preservation of capital and maintenance of liquidity.
 
Principal Investment Strategies
   
Salomon Brothers Asset Management Inc ("SBAM"), subadviser to the U.S.
Government Series, generally invests at least 80% of the assets of the U.S.
Government Series in fixed-income securities issued or guaranteed by the U.S.
Government or its agencies, authorities or instrumentalities ("U.S. Government
Securities") or in collateralized mortgage obligations ("CMOs") that relate to
such securities. The U.S. Government Series may also invest up to 20% of its
assets in INVESTMENT GRADE fixed-income securities that are not U.S. Government
Securities.     
 
Principal Investment Risks
 
Investing in the U.S. Government Series involves risks. The U.S. Government
Series may not perform as well as other investments, and it is possible for
investors to lose money. Factors that could harm the investment performance of
the U.S. Government Series include:
 
  . A general decline in fixed-income security markets.
     
  . Poor performance of the types of fixed-income securities in which U.S.
    Government Series invests relative to other fixed-income securities.     
 
  . Poor performance of individual fixed-income securities held by the U.S.
    Government Series, which may be due to interest rate risk and credit
    risk.
 
 
INVESTMENT GRADE: Moody's and Standard & Poor's are rating agencies that assign
a "credit rating" to fixed-income securities and issuers based on the agency's
evaluation of the risk that the issuer will default on its obligations.
Securities or issuers that earn one of the top four ratings from Moody's or
Standard & Poor's are considered "investment grade." In this Prospectus,
unrated securities that, in the subadviser's judgment, are of similar quality
to other securities rated investment grade are also referred to as investment
grade.

Investment Performance Record
   
The bar chart below shows the annual total return of the U.S Government Series
for each full calendar year since the Series began operations. The table
following the bar chart compares the average annual total returns of the U.S
Government Series to the returns of a relevant broad-based securities market
index and to returns of a group of other similar mutual funds underlying
variable insurance products. This information helps illustrate the volatility
of the returns of the U.S. Government Series, and does not reflect charges
associated with the Separate Accounts or variable contracts that an investor in
the Fund may pay under insurance or annuity contracts.

                        Back Bay Advisors Managed Series
 
Investment Objective
 
The investment objective of the Back Bay Advisors Managed Series (the "Managed
Series") is a favorable total return through investment in a diversified
portfolio.
 
Principal Investment Strategies
   
Back Bay Advisors, subadviser to the Managed Series, invests the assets of the
Managed Series in a portfolio of U.S. common stocks and U.S. and foreign fixed-
income securities. Back Bay Advisors will generally invest more of the assets
of Managed Series in common stocks than in fixed-income securities. The Managed
Series will generally invest in the stocks included in the S&P 500 Index and
may invest in INVESTMENT GRADE fixed-income securities, HIGH YIELD DEBT and
fixed-income securities of foreign issuers, including non-U.S. dollar
denominated securities.     
 
Principal Investment Risks
 
Investing in the Managed Series involves risks. The Managed Series may not
perform as well as other investments, and it is possible for investors to lose
money. Factors that could harm the investment performance of the Managed Series
include:
 
  . A general decline in the stocks included in the S&P 500 Index or U.S. or
    foreign fixed-income security markets.
 
  . Poor performance of individual equity securities or poor performance of
    fixed-income securities held by the Managed Series, which may be due to
    interest rate risk and credit risk.
 
  . Poor performance of equity securities relative to fixed-income securities
    when Back Bay Advisors emphasizes investment in equity securities, or
    poor performance of fixed-income securities relative to equity securities
    when Back Bay Advisors emphasizes investment in fixed-income securities.
 
  . Potentially rapid price changes (volatility) of equity securities.
     
  . The risks associated with investments in foreign securities. Foreign
    securities may be subject to less regulation and additional regional,
    national and currency risk. These risks are discussed more fully in
    Section III.     
 
 
INVESTMENT GRADE: Moody's and Standard & Poor's are rating agencies that assign
a "credit rating" to fixed-income securities and issuers based on the agency's
evaluation of the risk that the issuer will default on its obligations.
Securities or issuers that earn one of the top four ratings from Moody's or
Standard & Poor's are considered "investment grade." In this Prospectus,
unrated securities that, in the subadviser's judgment, are of similar quality
to other securities rated investment grade are also referred to as investment
grade.
 
Fixed-income securities that are below investment grade quality are referred to
as HIGH YIELD DEBT. High yield debt is typically riskier than investment grade
securities.

                         Loomis Sayles Balanced Series
 
Investment Objective
 
The investment objective of the Loomis Sayles Balanced Series (the "Balanced
Series") is reasonable long-term investment return from a combination of long-
term capital appreciation and moderate current income.
 
Principal Investment Strategies
   
Loomis, Sayles & Company, L.P. ("Loomis Sayles"), subadviser to the Balanced
Series, invests the assets of the Balanced Series in a mix of U.S. equity and
fixed-income securities. The Balanced Series invests at least 25% of its assets
in fixed-income securities. Loomis Sayles has the flexibility to invest the
remaining 75% of the assets of the Balanced Series in either equity or fixed-
income securities, depending on its economic and investment outlook, although
under normal market conditions more than 50% of the total assets of the
Balanced Series will be invested in stocks that Loomis Sayles regards as value
stocks.     
 
Principal Investment Risks
 
Investing in the Balanced Series involves risks. The Balanced Series may not
perform as well as other investments, and it is possible for investors to lose
money. Factors that could harm the investment performance of the Balanced
Series include:
 
  . A general decline in stock markets or fixed-income markets.
 
  . Poor performance of individual equity securities or poor performance of
    fixed-income securities held by the Balanced Series, which may be due to
    interest rate risk and credit risk.
     
  . Poor performance of equity securities relative to fixed-income securities
    when Loomis Sayles emphasizes investment in equity securities, or poor
    performance of fixed-income securities relative to equity securities when
    Loomis Sayles is relatively heavily invested in fixed-income securities.
        
  . Potentially rapid price changes (volatility) of equity securities.

The investment objective of the Alger Equity Growth Series ("Equity Growth") is
long-term capital appreciation.
 
Principal Investment Strategies
 
Fred Alger Management, Inc. ("Alger"), Equity Growth's investment subadviser,
invests Equity Growth's assets primarily in growth stocks. Alger will
ordinarily invest at least 65% of Equity Growth's total assets in equity
securities of issuers with market capitalization of $1 billion or greater.
 
Principal Investment Risks
 
Investing in Equity Growth involves risks. Equity Growth may not perform as
well as other investments, and it is possible for investors to lose money.
Factors that could harm the investment performance of Equity Growth include:
 
  . A general decline in U.S. stock markets.
 
  . Poor performance of individual stocks held by Equity Growth.
 
  . Potentially rapid price changes (volatility) of equity securities.

                             Capital Growth Series
 
Investment Objective
 
The investment objective of the Capital Growth Series ("Capital Growth") is the
long-term growth of capital through investment primarily in equity securities
of companies whose earnings are expected to grow at a faster rate than the
United States economy.
 
Principal Investment Strategies
   
CGM, Capital Growth's investment adviser, invests Capital Growth's assets
primarily in common stock of large capitalization U.S. companies whose earnings
CGM expects will grow at a faster rate than the United States economy. When
market conditions warrant, however, CGM may select stocks on the basis of
overall economic factors such as the general economic outlook, the level and
direction of interest rates and the potential impact of inflation. Capital
Growth invests primarily in equity securities of U.S. companies but may also
invest in equity securities of foreign issuers. Over time, Capital Growth has
held larger positions in a smaller number of issuers than many other mutual
funds. CGM does not consider income as a significant factor when selecting
investments for Capital Growth.     
 
Principal Investment Risks
 
Investing in Capital Growth involves risks. Capital Growth may not perform as
well as other investments, and it is possible for investors to lose money.
Factors that could harm the investment performance of Capital Growth include:
     
  . A general decline in U.S. or foreign stock markets.     
 
  . Poor performance of individual stocks held by Capital Growth.
 
  . Potentially rapid price changes (volatility) of equity securities.
     
  . The risks associated with investment in foreign securities. Foreign
    securities may be subject to less regulation and additional regional,
    national and currency risk. These risks are discussed more fully in
    Section III.

                           Davis Venture Value Series
 
Investment Objective
 
The investment objective of the Davis Venture Value Series ("Venture Value") is
growth of capital.
 
Principal Investment Strategies
   
Davis Selected Advisers, L.P. ("Davis Selected"), Venture Value's subadviser,
invests Venture Value's assets primarily in U.S. common stocks of companies
that have a market capitalization of at least $5 billion and that it believes
are of high quality and are selling at attractive prices. Davis Selected
generally selects stocks with the intention of holding them for the long term.
Davis Selected believes that managing risk is the key to delivering superior
long-term investment results; therefore, it considers how much could
potentially be lost on an investment before considering how much might be
gained.     
 
Principal Investment Risks
 
Investing in Venture Value involves risks. Venture Value may not perform as
well as other investments, and it is possible for investors to lose money.
Factors that could harm the investment performance of Venture Value include:
 
  . A general decline in the U.S. stock market.
 
  . Poor performance of individual stocks held by Venture Value.

                       Goldman Sachs Midcap Value Series
 
Investment Objective
 
The investment objective of the Goldman Sachs Midcap Value Series ("Midcap
Value") is long-term capital appreciation.
 
Principal Investment Strategies
   
Goldman Sachs Asset Management ("GSAM"), a separate operating division of
Goldman, Sachs & Co., invests, under normal circumstances, most of Midcap
Value's assets in equity securities that GSAM believes are relatively
underpriced and at least 65% of its total assets in equity securities of
companies with public stock market capitalizations within the range of the
market capitalization of companies constituting the Russell Midcap Index. GSAM
may invest up to 25% of Midcap Value's total assets in foreign securities
(including up to 15% of its total assets in securities issued in emerging
markets and securities the prices of which are quoted in foreign currencies).
In addition GSAM may invest 35% of Midcap Value's total assets in fixed-income
securities, including up to 10% of its total assets in HIGH YIELD DEBT. Midcap
Value does not focus on dividend income.     
 
Principal Investment Risks
 
Investing in Midcap Value involves risks. Midcap Value may not perform as well
as other investments, and it is possible for investors to lose money. Factors
that could harm the investment performance of Midcap Value include:
     
  . A general decline in U.S. or foreign stock markets or fixed-income
    securities markets.     
 
  . Poor performance of individual stocks or fixed-income securities held by
    Midcap Value.
 
  . Potentially rapid price changes (volatility) of equity securities.
     
  . The risks associated with investments in foreign securities. Foreign
    securities may be subject to less regulation and additional regional,
    national and currency risk. These risks are discussed more fully in
    Section III.     
 
INVESTMENT GRADE: Moody's and Standard & Poor's are rating agencies that assign
a "credit rating" to fixed-income securities and issuers based on the agency's
evaluation of the risk that the issuer will default on its obligations.
Securities or issuers that earn one of the top four ratings from Moody's or
Standard & Poor's are considered "investment grade." In this Prospectus,
unrated securities that, in the subadviser's judgment, are of similar quality
to other securities rated investment grade are also referred to as investment
grade.
 
Fixed-income securities that are below investment grade quality are referred to
as HIGH YIELD DEBT. High yield debt is typically riskier than investment grade
securities.

Investment Performance Record
   
The bar chart below shows the annual total return of Midcap Value for each full
calendar year since the Series began operations. The table following the bar

May 1, 1998, GSAM succeeded Loomis Sayles as subadviser to Midcap Value. The
performance information set forth below relates to the life of the Series and
therefore, reflects the management of both GSAM and Loomis Sayles.

                         Loomis Sayles Small Cap Series
 
Investment Objective
 
The investment objective of the Loomis Sayles Small Cap Series ("Small Cap") is
long-term capital growth from investments in common stocks or their
equivalents.
 
Principal Investment Strategies
   
Loomis, Sayles & Company, L.P. ("Loomis Sayles"), Small Cap's subadviser will
invest, under normal market conditions, at least 65% of Small Cap's total
assets in equity securities of U.S. companies with market capitalizations that
fall within the capitalization range of those companies constituting the
Russell 2000 Index. Small Cap invests in both value and growth stocks.     
 
Principal Investment Risks
 
Investing in Small Cap involves risks. Small Cap may not perform as well as
other investments, and it is possible for investors to lose money. Factors that
could harm the investment performance of Small Cap include:
 
  . A general decline in the U.S stock market.
 
  . Poor performance of individual stocks held by Small Cap.
 
  . Potentially rapid price changes (volatility) of equity securities.
 
  . Poor performance of small capitalization issuers relative to the
    performance of issuers with larger capitalizations.

Principal Investment Strategies
 
Massachusetts Financial Services Company ("MFS"), subadviser to the Investors
Series, ordinarily invests at least 65% of the total assets of the Investors
Series in equity securities. Although the Series may invest in companies of any
size, the Series focuses on companies with large market capitalizations

Investment Objective
 
The investment objective of the MFS Research Managers Series (the "Research
Managers Series") is long-term growth of capital.

Managers Series in equity securities. The Series invests primarily in companies
that MFS believes possess better than average prospects for long-term growth
and attractive valuations. MFS may also invest up to 20% of the net assets of
the Series in foreign securities.
 
Principal Investment Risks
 
Investing in the Research Managers Series involves risks. The Research Managers
Series may not perform as well as other investments, and it is possible for
investors to lose money. Factors that could harm the investment performance of
the Research Managers Series include:
     
  . A general decline in U.S. or foreign stock markets.

                       Westpeak Growth and Income Series
 
Investment Objective
 
The investment objective of the Westpeak Growth and Income Series ("Growth and
Income") is long-term total return through investment in equity securities.
 
Principal Investment Strategies
 
Westpeak Investment Advisors, L.P., Growth and Income's subadviser, is not
limited to either the growth or value style of investing. Westpeak sometimes
invests more of Growth and Income's assets in value stocks, and sometimes
invests more heavily in growth stocks. Growth and Income invests primarily in
stocks of large capitalization U.S. companies, such as those included in the
S&P 500 Index, but it may also invest in securities of other large
capitalization companies. Westpeak emphasizes individual stock selection rather
than targeting particular industries or sectors that it believes may outperform
other sectors.
 
Principal Investment Risks
 
Investing in Growth and Income involves risks. Growth and Income may not
perform as well as other investments, and it is possible for investors to lose
money. Factors that could harm the investment performance of Growth and Income
include:
     
  . A general decline in the U.S. stock market.     
 
  . Poor performance of individual stocks held by Growth and Income.
 
  . Potentially rapid price changes (volatility) of equity securities.
 
  . Poor performance of growth stocks relative to value stocks when Westpeak
    emphasizes investment in growth stocks, or poor performance of value
    stocks relative to growth stocks when Westpeak emphasizes investment in
    value stocks.

                          Westpeak Stock Index Series
 
Investment Objective
 
The investment objective of the Westpeak Stock Index Series ("Stock Index") is
investment results that correspond to the composite price and yield performance
of United States publicly traded common stocks.
 
Principal Investment Strategies
 
Westpeak, subadviser to Stock Index, attempts to duplicate the composite price
and yield performance of the S&P 500 Index.
 
Westpeak will ordinarily invest Stock Index's assets in all of the 500 stocks
included in the S&P 500 Index. Each month, Westpeak purchases and sells stocks
as necessary to duplicate the proportions of stocks included in the S&P 500
Index.
 
Principal Investment Risks
 
Investing in Stock Index involves risks. Stock Index may not perform as well as
other investments, and it is possible for investors to lose money. Factors that
could harm the investment performance of Stock Index include:
 
  . A general decline in the value of stocks included in the S&P 500 Index.
 
  . Potentially rapid price changes (volatility) of equity securities.
 
Investment Performance Record
   
The bar chart below shows the annual total return of Stock Index for the last
ten full calendar years. The table following the bar chart compares the average
annual total returns of Stock Index to the returns of a relevant broad-based
securities market index and to returns of a group of other similar mutual funds

Westpeak succeeded Back Bay Advisors as subadviser to Stock Index. The

               Morgan Stanley International Magnum Equity Series
 
Investment Objective
 
The investment objective of the Morgan Stanley International Magnum Equity
Series ("International Equity") is long-term capital appreciation through
investment primarily in international equity securities.
 
Principal Investment Strategies
   
Morgan Stanley Asset Management ("MSAM") is International Equity's subadviser.
On December 1, 1998, Morgan Stanley Asset Management Inc. changed its name to
Morgan Stanley Dean Witter Investment Management Inc. but continues to do
business in certain instances (including as subadviser to International Equity)
using the name Morgan Stanley Asset Management. MSAM invests International
Equity's assets in a diversified portfolio of stocks of foreign issuers
domiciled in EAFE COUNTRIES. MSAM seeks to achieve superior long-term returns
by creating a diversified portfolio of stocks that MSAM believes are
undervalued. To achieve this goal, MSAM implements a combination of strategic
geographic asset allocation and fundamental, value-oriented stock selection
implemented by regional experts around the globe.     
 
Principal Investment Risks
 
Investing in International Equity involves risks. International Equity may not
perform as well as other investments, and it is possible for investors to lose
money. Factors that could harm the investment performance of International
Equity include:
     
  . A general decline in foreign stock markets.     
 
  . Poor performance of the stock markets in which International Equity
    invests relative to the performance of other stock markets.
 
  . Poor performance of individual stocks held by International Equity.
 
  . Potentially rapid price changes (volatility) of equity securities.
     
  . The risks associated with investments in foreign securities. Foreign
    securities may be subject to less regulation and additional regional,
    national and currency risk. These risks are discussed more fully in
    Section III.     
 
 
EAFE COUNTRIES are countries included in the Morgan Stanley Capital

approximately 20 countries, including Australia, New Zealand, many nations in

Investment Performance Record
   
The bar chart below shows the annual total return of International Equity for
each full calendar year since the Series began operations. The table following
the bar chart compares the average annual total returns of International Equity
to the returns of a relevant broad-based securities market index and to returns
of a group of other similar mutual funds underlying variable insurance
products. This information helps illustrate the volatility of International
Equity's returns, and does not reflect charges associated with the Separate
Accounts or variable contracts that an investor in the Fund may pay under
insurance or annuity contracts. On May 1, 1997, MSAM succeeded Draycott
Partners, Ltd. as subadviser to International Equity. The performance
information set forth below relates to the life of the Series and, therefore,
reflects the management of both MSAM and Draycott Partners, Ltd.

             Section III--Additional Information about each Series
 
This Section contains additional information that may help you decide whether
and how much to invest in each Series. This Section discusses the principal
strategies and risks of investing in each Series. However, each Series may
invest in securities and engage in certain investment practices not discussed
below or in the Summary. For more information about these securities,
strategies and related risks, please see "Investment Risks" in the Fund's
Statement of Additional Information (the "SAI"). Please call the toll free
number listed on the back cover of the Prospectus to receive a free copy of the
SAI.
       
Temporary Defensive Positions
 
Each Series other than Money Market and Stock Index may, for temporary
defensive purposes, hold all or a substantial portion of its assets in cash or
fixed-income investments. The types of securities in which a Series may invest
include U.S. Government securities, investment grade fixed-income securities,
money market instruments and REPURCHASE AGREEMENTS. No estimate can be made as
to when or for how long a Series may employ a defensive strategy. Although a
defensive strategy may help insulate a Series from a downturn in securities
markets, it could prevent the Series from capturing the gains it would
otherwise achieve if the Series did not employ a defensive strategy.
 
Portfolio Turnover
 
Each Series may engage in active and frequent trading of portfolio securities
to achieve its principal investment strategies. As a result, the Series may
experience high portfolio turnover. High portfolio turnover results in higher
brokerage and other transaction costs.
 
Investment Restrictions
 
Each Series is restricted as to the types of investments it may make. These
restrictions are described in detail in the SAI. Some investment restrictions
are "fundamental," which means that the Fund's Trustees may only change them
after obtaining shareholder approval. The investment objective of each Series
may be changed without shareholder approval, except for the investment
objectives of the following Series: Small Cap, Bond Income, Capital Growth,
Growth and Income, Managed, Money Market and Stock Index.
 
Investment Percentage Requirements and Capitalization
 
Several of the Series have adopted policies that set minimum or maximum
percentages of their assets to be allocated to certain types of investments or
to certain ranges of market capitalization. These percentage requirements and
capitalization ranges apply at the time an investment is made; a change in the
value of an investment after it is acquired is not treated as a violation of
these policies or ranges.
 
 
 
REPURCHASE AGREEMENTS are agreements under which a Series purchases one or more
securities from another party, usually a bank or a brokerage firm, with the
understanding that the counterparty will buy the securities back from the
Series at a later date. Repurchase agreements allow a Series to earn a return
on available cash at relatively low credit risk.

                     Back Bay Advisors Money Market Series
 

REPURCHASE AGREEMENTS are agreements under which a Series purchases one or more
securities from another party, usually a bank or a brokerage firm, with the
understanding that the counterparty will buy the securities back from the
Series at a later date. Repurchase agreements allow a Series to earn a return
on available cash at relatively low credit risk.
 
CREDIT RISK is the risk that the security's issuer will not pay the interest,
dividends or principal that it has promised to pay.
 
MARKET RISK is the risk that the value of the security will fall because of
changes in market rates of interest or other factors.
 
Some securities pay a higher interest rate than the current market rate. An
investor may have to pay more than the security's principal to compensate the
seller for the value of the higher interest rate. This additional payment is a
PREMIUM.

Principal Investment Strategies
 
Back Bay Advisors invests Money Market's assets in a managed portfolio of money
market instruments.
 
 Investment selection
 
Money market instruments are short term fixed-income investments that include
the following:
 
  . Obligations backed by the full faith and credit of the United States
    Government, and other obligations issued or guaranteed by the United
    States Government or its agencies, authorities or instrumentalities.
 
  . Commercial paper and other corporate debt obligations rated in the
    highest rating category by S&P or Moody's (or, if unrated, of comparable
    quality).
 
  . REPURCHASE AGREEMENTS.
 
  . Obligations of banks or savings and loan associations with net assets of
    more than $100 million.
 
Principal Investment Risks
 
 Fixed-income Securities
 
Because of the short maturity and high credit quality of money market
instruments, the risks associated with these instruments is generally lower
than the risks associated with other fixed-income securities.
 
The value of most fixed-income securities generally will rise when interest
rates decline and fall when interest rates rise. Fixed-income securities
involve both CREDIT RISK and MARKET RISK. Some fixed-income securities also
involve the risk that an issuer will repay the principal or repurchase the
security before it matures. If this happens, the holder will no longer receive
any interest on that security. The holder could buy another security, but that
other security might pay a lower interest rate. Also, if the holder paid a
premium when it bought the security, the holder may receive less from the
issuer than it paid for the security.
 
Portfolio Management
   
As of December 31, 1998, Back Bay Advisors managed approximately $9.5 billion
in assets. In addition to Series of the Fund, Back Bay Advisors advises 10
mutual funds and several institutional accounts. Back Bay Advisors is located
at 399 Boylston Street, Boston, Massachusetts 02116.     
   
During the year ended December 31, 1998, Money Market paid 0.35% of its average
net assets in investment advisory fees and its total operating expenses were
0.45% of such assets.

                      Back Bay Advisors Bond Income Series
 
Principal Investment Strategies
 
Back Bay Advisors invests Bond Income's assets primarily in fixed-income
securities. Back Bay Advisors will invest at least 80% of Bond Income's assets
in investment grade securities, and may invest up to 10% of Bond Income's
assets in obligations of foreign issuers.
 
 Investment Selection
 
Back Bay Advisors evaluates potential investments for Bond Income in several
steps.
 
Back Bay Advisors first allocates the assets of Bond Income that are available
for investment among three principal areas: corporate securities, mortgage-
backed securities and U.S. Treasury securities. Back Bay Advisors makes this
allocation based on its analysis of current and future interest rate trends and
market indicators. Once Back Bay Advisors makes this allocation, it searches
for investment opportunities in each area.
 
When evaluating domestic and foreign corporate fixed-income securities, Back
Bay Advisors first considers the relative attractiveness of corporate
securities in four different sectors: industrial, financial, utilities, and
YANKEE. Back Bay Advisors allocates assets among the four sectors based on its
evaluation of the relative merits of each sector and its market outlook. Back
Bay Advisors next analyzes the credit quality of specific issuers and the
market prices of securities of those issuers.
 
When evaluating mortgage-backed securities, Back Bay Advisors reviews the
creditworthiness and likelihood of prepayment on the mortgages underlying those
securities.
 
When evaluating U.S. Treasury securities, Back Bay Advisors considers the
difference between the interest rates on U.S. Treasury securities of various
maturities and the interest rates on other fixed-income securities.
 
Back Bay Advisors generally attempts to maintain a duration for the Bond Income
portfolio that is within 1 1/2 years of the duration of the Lehman Aggregate
Bond Index.

CREDIT RISK is the risk that the security's issuer will not pay the interest,
dividends or principal that it has promised to pay.
 
MARKET RISK is the risk that the value of the security will fall because of
changes in market rates of interest or other factors.

LEVERAGE in this context is a measure of how much a company has borrowed in
relation to its shareholders' equity.
 
A FORWARD CONTRACT is an agreement to buy or sell securities or currencies on a
specified future date at a specific price.
 
A FUTURES CONTRACT is an obligation to buy or sell an asset on a specified
future date or an obligation to pay or receive money based on the value of some
securities index or currency or interest rate on a specified future date.
Typically, futures contracts are traded on an exchange (rather than entered
into between two parties). Futures contracts are one kind of DERIVATIVE.
 
A DERIVATIVE is a financial instrument whose value is based on (derived from)
changes in the value of something else, such as a currency, an interest rate or
a security.


PREMIUM when it bought the security, the holder might receive less from the
issuer than it paid for the security.
 
 High yield debt
 
High yield debt has a higher credit risk and market risk than investment grade
fixed-income securities. Issuers could have high credit risk for many reasons,
including problems with product development or distribution, reductions in
market share or overall sales, competition in their markets or a high degree of
LEVERAGE. High yield debt has higher market risk for a variety of reasons,
including greater sensitivity to interest rate changes and economic downturns,
and the difficulty some issuers may have when trying to obtain additional
financing. Also, high yield debt may be difficult to value, and if other
investors believe that a certain issuer's securities are overvalued, the holder
may be unable to sell those securities for what it believes is an adequate
price.
 
 Foreign Securities
 
In addition to the risks associated with equity securities generally, foreign
securities present additional risks.
 
Regulation and Access to Information. Changes in foreign countries' laws may
harm the performance and liquidity of the Series' investments in those
countries. Additionally, many countries have less stringent financial reporting
requirements than the United States, so it may be difficult to obtain
information to evaluate the business potential of foreign issuers.
 
Regional and National Risk. News and events unique to particular regions and
foreign countries will affect non-U.S. markets and issuers. These same events
may not affect the U.S. economy or similar issuers located in the United States
in the same manner. As a result, movements in the prices of foreign securities
may not correlate with the prices of U.S. securities.
 
Currency Risk. As many investments in foreign countries are denominated in
foreign currencies, changes in the value of those countries' currencies
relative to the U.S. dollar may affect the value of those investments. These
changes may occur in response to events unrelated to the value of the security
in the issuer's home country. Back Bay Advisors may use certain techniques,
such as FORWARD CONTRACTS or FUTURES CONTRACTS, to manage these risks. However,
Back Bay Advisors cannot assure that these techniques will be effective.
 
 Forward Contracts and Futures
 
The Series may seek to avoid the risk of an unfavorable shift in currency rates
by entering into forward contracts or buying or selling futures contracts or
options on futures contracts.
 
Forward contracts. By entering into a forward contract, Bond Income is giving
up the potential gains (and avoiding the potential
 
                                      B-36
<PAGE>
 
losses) that may occur if the actual exchange rate on the specified date is
different from the exchange rate established in the contract.
 
Futures contracts. If the price of a futures contract changes more than the
price of the security or index on which the contract is based, Bond Income
could make or lose more money than if it had invested directly in the
underlying security or index. This added volatility increases the risk of these
investments. In addition, investors may be unwilling to buy or sell futures
contracts under some market conditions. If this happens, Bond Income might not
be able to close out futures transactions without incurring substantial losses.
 
Portfolio Management
   
As of December 31, 1998, Back Bay Advisors managed approximately $9.5 billion
in assets. In addition to Series of the Fund, Back Bay Advisors manages 10
mutual funds and several institutional accounts. Back Bay Advisors is located
at 399 Boylston Street, Boston, Massachusetts 02116.     
 
Catherine L. Bunting is primarily responsible for the day-to-day management of
Bond Income. Ms. Bunting is a Senior Vice President of Back Bay Advisors and
has served as Bond Income's portfolio manager since January 1989.
   
During the fiscal year ended December 31, 1998, Bond Income paid 0.40% of its
average net assets in investment advisory fees and its total operating expenses
were 0.48% of such assets.

              Salomon Brothers Strategic Bond Opportunities Series
 
   
DURATION is an estimate of how much a bond fund's share price will fluctuate in
response to a change in interest rates. To see how the price could shift,
multiply the Series' duration by the change in rates. If interest rates rise by
one percentage point, the share price of a fund with an average duration of
five years would decline by about 5%. If rates decrease by a percentage point,
the fund's share price would rise by 5%.     
 
CREDIT RISK is the risk that the security's issuer will not pay the interest,
dividends or principal that it has promised to pay.
 
MARKET RISK is the risk that the value of the security will fall because of
changes in market rates of interest or other factors.
 
Some securities pay a higher interest rate than the current market rate. An
investor may have to pay more than the security's principal to compensate the
seller for the value of higher interest rate. This additional payment is a
PREMIUM.

Principal Investment Strategies
   
SBAM invests substantially all of Strategic Bond's assets in three classes of
fixed-income securities: (1) U.S. investment grade securities (including U.S.
Government obligations), (2) U.S. and foreign high yield debt, and (3) foreign
government securities.     
 
 Investment Selection
 
SBAM determines how to invest Strategic Bond assets in several steps:
 
SBAM has an investment committee consisting of senior portfolio managers which
analyzes current interest rate trends and their impact on potential economic
scenarios. This committee meets every month to revise its estimate of interest
rate and general market trends. Based on this analysis, Strategic Bond's
portfolio managers allocate assets among the various classes of securities in
which the Series invests. Once this allocation is set, SBAM focuses on specific
investment opportunities within those areas.
   
SBAM considers many factors when selecting individual fixed-income securities,
including the interest rate of the security, the interval at which the interest
rate adjusts, the date of maturity of the security and the creditworthiness of
the issuer. SBAM also considers Strategic Bond's likely need for liquidity,
which can be influenced by redemptions (and opportunities for purchases of
other securities), and the DURATION of the portfolio, which will generally be
approximately 4.5 years.

The value of most fixed-income securities generally will rise when interest

Series' investments in those countries. Additionally, many countries have less
stringent financial reporting requirements than the United States, so it may be
difficult to obtain information to evaluate the business potential of foreign
issuers.
 
Regional and National Risk. News and events unique to particular regions and
foreign countries will affect non-U.S. markets and issuers. These same events
may not affect the U.S. economy or similar issuers located in the United States
in the same manner. As a result, movements in the prices of foreign securities
may not correlate with the prices of U.S. securities.
 
Currency Risk. As many investments in foreign countries are denominated in
foreign currencies, changes in the value of those countries' currencies
relative to the U.S. dollar may affect the value of those investments. These
changes may occur in response to events unrelated to the value of the security
in the issuer's home country. SBAM may use certain techniques, such as FORWARD
CONTRACTS or FUTURES CONTRACTS, to manage these risks. However, SBAM cannot
assure that these techniques will be effective.
 
 Forward Contracts and Futures
 
The Series may seek to avoid the risk of an unfavorable shift in currency rates
by entering into forward contracts or buying or selling futures contracts or
options on futures contracts.
 
Forward contracts. By entering into a forward contract, Strategic Bond is
giving up the potential gains (and avoiding the potential losses) that may
occur if the actual exchange rate on the specified date is different from the
exchange rate established in the contract.
 
Futures contracts. If the price of a futures contract changes more than the
price of the security or index on which the contract is based, Strategic Bond
could make or lose more money than if it had invested directly in the
underlying security or index. This added volatility increases the risk of these
investments. In addition, investors may be unwilling to buy or sell futures
contracts under some market conditions. If this happens, Strategic Bond might
not be able to close out futures transactions without incurring substantial
losses.
 
 Emerging Markets
 
Strategic Bond may invest in emerging markets, which are generally located in
the Asia-Pacific Region, Eastern Europe, Latin and South America and Africa. In
addition to the risks of foreign securities described above (which are
potentially greater for emerging markets securities than for other foreign
securities), emerging markets securities may be subject to other risks,
including increased risks of reduced liquidity, high inflation rates, political
uncertainty, high administrative and regulatory costs, repatriation of income
and less advantageous investment terms relative to foreign nationals.

A FORWARD CONTRACT is an agreement to buy or sell securities or currencies on a
specified future date at a specific price.
 
A FUTURES CONTRACT is an obligation to buy or sell an asset on a specified
future date or an obligation to pay or receive money based on the value of some
securities index or currency or interest rate on a specified future date.
Typically, futures contracts are traded on an exchange (rather than entered
into between two parties). Futures contracts are one kind of DERIVATIVE.
 
A DERIVATIVE is a financial instrument whose value is based on (derived from)

 High Yield Debt
 
High yield debt has a higher credit risk and market risk than investment grade
fixed-income securities. Issuers could have high credit risk for many reasons,
including problems with product development, distribution or competition in
their markets or a high degree of LEVERAGE. High yield debt has higher market

trying to obtain additional financing. Also, high yield debt may be difficult
to value, and if other investors believe that a certain issuer's securities are
overvalued, the holder may be unable to sell those securities for what it
believes is an adequate price.
 
 High Yield, High Risk Foreign Securities
 
SBAM may invest up to 100% of Strategic Bond's total assets in high yield, high
risk foreign securities. High yield, high risk foreign securities are typically
issued by emerging countries, and will therefore be subject to emerging market
risks in addition to risks of foreign securities described above. Other risks
may include high interest rates and under collateralization.
 
Portfolio Management
   
As of December 31, 1998, SBAM managed approximately $29 billion in assets. SBAM
is located at 7 World Trade Center, New York, New York 10048.     
   
SBAM may delegate to its affiliate, Salomon Brothers Asset Management Limited
("SBAM Ltd."), any of its responsibilities with respect to transactions of
Strategic Bond in foreign currencies and debt securities denominated in foreign
currencies. SBAM Ltd. is located at Victoria Plaza, 111 Buckingham Palace Road,
London SW1W OSB, England.     
 
Roger Lavan is primarily responsible for the day-to-day management of the
investment grade portion of Strategic Bond's portfolio. Mr. Lavan joined SBAM
as the Director and Portfolio Manager in 1990.
 
Peter Wilby is primarily responsible for the day-to-day management of the high
yield and foreign sovereign securities portion of Strategic Bond's portfolio.
Mr. Wilby joined SBAM in 1989 and is a Managing Director of SBAM.
 
David Scott is primarily responsible for the day-to-day management of currency
transactions and certain non-dollar denominated debt securities investments of
Strategic Bond's portfolio. Mr. Scott joined SBAM in 1994 and is a Managing
Director of SBAM.
   
During the year ended December 31, 1998, Strategic Bond paid 0.65% of its
average net assets in investment advisory fees and its total operating expenses
were 0.85% of such assets.

                    Salomon Brothers U.S. Government Series
 
Principal Investment Strategies
 
SBAM generally invests at least 80% of the assets of the U.S. Government Series
in U.S. Government Securities or in CMOs that relate to such securities. The
U.S. Government Series may also invest up to 20% of its assets in investment
grade fixed-income securities that are not U.S. Government Securities.
 
 Investment Selection

SBAM determines how to invest assets of the U.S. Government Series in several
steps.
   
SBAM has an investment committee consisting of senior portfolio managers which
analyzes current interest rate trends and their impact on potential economic
scenarios. This committee meets every month to revise its estimate of interest
rate and general economic trends. Based on this analysis, portfolio managers of
the Series allocate assets among various classes of securities, including U.S.
Treasury securities and securities of agencies or instrumentalities of the U.S.
Government, mortgage-backed assets and investment grade fixed-income securities.
The mortgage-backed assets in which the Series invests include GNMA and FNMA
mortgage-backed securities and other privately issued mortgage-backed
securities, including CMOs.     

SBAM considers many factors when selecting individual fixed-income securities,
including the interest rate of the security, the interval at which that
interest rate adjusts, the date of maturity of the security and the
creditworthiness of the issuer. SBAM also considers the U.S. Government Series'
likely need for liquidity, which can be influenced by redemptions and
opportunities for purchases of other securities, and the DURATION of the
portfolio, which typically fluctuates between 2.5 and 5 years.
 
Principal Investment Risks
 
 Fixed-income Securities
     
The value of most fixed-income securities generally will rise when interest
rates decline and fall when interest rates rise. Fixed-income securities
involve both CREDIT RISK and MARKET RISK. Some fixed-income securities also
involve the risk that an issuer will repay the principal or repurchase the
security before it matures. If this happens, the holder will no longer receive
any interest on that security. The holder could buy another security, but that
other security might pay a lower interest rate. Also, if the holder paid a

issuer than it paid for the security.      
   
DURATION is an estimate of how much a bond fund's share price will fluctuate in
response to a change in interest rates. To see how the price could shift,
multiply the Series' duration by the change in rates. If interest rates rise by
one percentage point, the share price of a fund with an average duration of
five years would decline by about 5%. If rates decrease by a percentage point,
the fund's share price would rise by 5%.     
 
CREDIT RISK is the risk that the security's issuer will not pay the interest,
dividends or principal that it has promised to pay.
 
MARKET RISK is the risk that the value of the security will fall because of
changes in market rates of interest or other factors.

Collateralized Mortgage Obligations (CMOs). One type of security in which the
U.S. Government Series can invest is a CMO. CMOs are fixed-income securities
that are collateralized by a portfolio of mortgages or mortgage securities. The
underlying mortgages or mortgage securities of the CMOs purchased by the U.S.
Government Series are issued or guaranteed by the U.S. Government or one of its
agencies or instrumentalities, but the CMOs themselves may not be so issued or
guaranteed. Therefore, CMOs are often riskier than other U.S. Government
Securities.     
 
Portfolio Management
   
As of December 31, 1998, SBAM managed approximately $29 billion in assets. SBAM
is located at 7 World Trade Center, New York, New York 10048.     
   
Roger Lavan has been primarily responsible for the day-to-day management of
U.S. Government Bond since 1997. Mr. Lavan joined SBAM as Director and
Portfolio Manager in 1990 and served as a co-portfolio manager of U.S.
Government Bond from its inception until 1997.     
   
During the year ended December 31, 1998, U.S. Government Bond paid 0.55% of its
average net assets in investment advisory fees and its total operating expenses
were 0.70% of such assets.     
 
Some securities pay a higher interest rate than the current market rate. An
investor may have to pay more than the security's principal to compensate the
seller for the value of the higher interest rate. This additional payment is
called a PREMIUM.

                        Back Bay Advisors Managed Series
 
Principal Investment Strategies
   
Back Bay Advisors invests the assets of the Managed Series in a portfolio of
U.S. common stocks and U.S. and foreign fixed-income securities. Back Bay
Advisors will generally invest more of the assets of Managed Series in common
stocks than in fixed-income securities. The Managed Series will generally
invest in the stocks included in the S&P 500 Index and may invest in investment
grade fixed-income securities, high yield debt and fixed-income securities of
foreign issuers, including non-dollar denominated securities.     
 
 Investment Selection
 
Back Bay Advisors evaluates potential investments for the Managed Series in
several steps.
 
Each week, Back Bay Advisors uses a quantitative model to evaluate and adjust
the Managed Series' allocation of assets between equity and fixed-income
securities. This model analyzes U.S. Government monetary policy, the relative
valuation of stock markets relative to fixed-income markets and the flow of
funds between stock markets and fixed-income markets.
 
Equity Securities. Back Bay Advisors generally invests all of the Managed
Series' equity portfolio in stocks included in the S&P 500. Back Bay Advisors
uses quantitative analysis to invest approximately 20% of this portfolio in
value stocks. Back Bay Advisors invests the remaining 80% of this portfolio to
reflect individual stock and industry sector weightings of the S&P 500.
 
Fixed-Income Securities. Back Bay Advisors first allocates the assets of the
Managed Series that will be invested in fixed-income securities among three
areas: corporate securities, mortgage-backed securities and U.S. Treasury
securities. Back Bay Advisors makes this allocation based on its analysis of
current and future interest rate trends and market indicators. Once Back Bay
Advisors makes this allocation, it searches for investment opportunities in
each area.
 
When evaluating corporate fixed-income securities, Back Bay Advisors first
considers the relative attractiveness of domestic and foreign corporate
securities in four different sectors: industrial, financial, utilities, and
YANKEE. Back Bay Advisors allocates assets among the four sectors based on its
evaluation of the relative merits of each sector and its market outlook. Back
Bay Advisors next analyzes the credit quality of specific issuers and the
market prices of securities of those issuers.
 
When evaluating mortgage-backed securities, Back Bay Advisors reviews the
creditworthiness and likelihood of prepayment on the mortgages underlying those
securities.
 
When evaluating U.S. Treasury securities, Back Bay Advisors considers the
difference between the interest rates on U.S. Treasuries of various maturities
and the interest rates on other fixed-income securities.
   
The YANKEE sector consists of senior debt issued by foreign companies in U.S.
dollars.

DURATION is an estimate of how much a bond fund's share price will fluctuate in
response to a change in interest rates. To see how the price could shift,
multiply the Series' duration by the change in rates. If interest rates rise by
one percentage point, the share price of a fund with an average duration of
five years would decline by about 5%. If rates decrease by a percentage point,
the fund's share price would rise by 5%.     
 
CREDIT RISK is the risk that the security's issuer will not pay the interest,
dividends or principal that it has promised to pay.
 
MARKET RISK is the risk that the value of the security will fall because of
changes in market rates of interest or other factors.
     
Some securities pay a higher interest rate than the current market rate. An
investor may have to pay more than the security's principal to compensate the
seller for the value of the higher interest rate. This additional payment is
called a PREMIUM.      
 
LEVERAGE in this context is a measure of how much a company has borrowed in
relation to its shareholders' equity.
   
The DURATION of the fixed-income securities portfolio of the Managed Series may
vary widely; generally, the duration will range from 5 to 10 years.     
 
Principal Investment Risks
 
 Equity Securities
 
In general, equity securities are considered more volatile than fixed-income
securities. The prices of equity securities will rise and fall in response to
events that affect entire financial markets or industries (changes in inflation
or consumer demand, for example) and to events that affect particular companies
(news about the success or failure of a new product, for example).
 
Growth Stocks and Value Stocks. The prices of growth stocks may be more
sensitive to changes in current or expected earnings than the prices of other
stocks.
 
 Fixed-income Securities
 
The value of most fixed-income securities generally will rise when interest
rates decline and fall when interest rates rise. Fixed-income securities
involve both CREDIT RISK and MARKET RISK. Some fixed-income securities also
involve the risk that an issuer will repay the principal or repurchase the
security before it matures. If this happens, the holder will no longer receive
any interest on that security. The holder could buy another security, but that
other security might pay a lower interest rate. Also, if the holder paid a
PREMIUM when it bought the security, the holder might receive less from the
issuer than it paid for the security.
 
 High yield debt
 
High yield debt has a higher credit risk and market risk than investment grade
fixed-income securities. Issuers could have high credit risk for many reasons,
including problems with product development or distribution, reductions in
market share or overall sales, competition in their markets or a high degree of
LEVERAGE. High yield debt has higher market risk for a variety of reasons,
including greater sensitivity to interest rate changes and economic downturns,
and the difficulty some issuers may have when trying to obtain additional
financing. Also, high yield debt may be difficult to value, and if other
investors believe that a certain issuer's securities are overvalued, the holder
may be unable to sell those securities for what it believes is an adequate
price.
 
 Foreign Securities
 
In addition to the risks associated with equity securities generally, foreign
securities present additional risks.
 
Regulation and Access to Information. Changes in foreign countries' laws may
harm the performance and liquidity of the Series' investments in those
countries. Additionally, many countries have less stringent financial reporting
requirements than the United States, so it may be difficult to obtain
information to evaluate the business potential of foreign issuers.
 
                                      B-44
<PAGE>
 
Regional and National Risk. News and events unique to particular regions and
foreign countries will affect non-U.S. markets and issuers. These same events
may not affect the U.S. economy or similar issuers located in the United States
in the same manner.
 
As a result, movements in the prices of foreign securities may not correlate
with the prices of U.S. securities.
     
Currency Risk. As many investments in foreign countries are denominated in
foreign currencies, changes in the value of those countries' currencies
relative to the U.S. dollar may affect the value of those investments. These
changes may occur in response to events unrelated to the value of the security
in the issuer's home country. Back Bay Advisors may use certain techniques,
such as FORWARD CONTRACTS or FUTURES CONTRACTS, to manage these risks. However,
Back Bay Advisors cannot assure that these techniques will be effective.      
 
 Forward Contracts and Futures
 
The Series may seek to avoid the risk of an unfavorable shift in currency rates
by entering into forward contracts or buying or selling futures contracts or
options on futures contracts.
 
Forward contracts. By entering into a forward contract, the Managed Series is
giving up the potential gains (and avoiding the potential losses) that may
occur if the actual exchange rate on the specified date is different from the
exchange rate established in the contract.
 
Futures contracts. If the price of a futures contract changes more than the
price of the security or index on which the contract is based, the Managed
Series could make or lose more money than if it had invested directly in the
underlying security or index. This added volatility increases the risk of these
investments. In addition, investors may be unwilling to buy or sell futures
contracts under some market conditions. If this happens, the Managed Series
might not be able to close out futures transactions without incurring
substantial losses.
 
Portfolio Management
   
As of December 31, 1998, Back Bay Advisors managed approximately $9.5 billion
in assets. In addition to Series of the Fund, Back Bay Advisors advises 10
mutual funds and several institutional accounts. Back Bay Advisors is located
at 399 Boylston Street, Boston, Massachusetts 02116.     
 
Peter Palfrey is primarily responsible for the day-to-day management of the
Managed Series. Mr. Palfrey is a Vice President of Back Bay Advisors and has
served as portfolio manager of the Managed Series since January 1994.
   
During the year ended December 31, 1998, the Managed Series paid 0.50% of its
average net assets in investment advisory fees and its total operating expenses
were 0.58% of such assets.     
     
A FORWARD CONTRACT is an agreement to buy or sell securities or currencies on a
specified future date at a specific price.      
     
A FUTURES CONTRACT is an obligation to buy or sell an asset on a specified
future date, or to pay or receive money based on the value of some securities
index or currency or interest rate on a specified future date. Typically,
futures contracts are traded on an exchange (rather than entered into between
two parties). Futures contracts are one kind of DERIVATIVE.      
     
A DERIVATIVE is a security, the value of which is based on (derived from) the
movement of an underlying instrument. This instrument could be the price of
another security or other asset or an interest rate, among other things.

                         Loomis Sayles Balanced Series
 
Principal Investment Strategies
 
Loomis Sayles invests the assets of the Balanced Series in a mix of equity and
fixed-income securities. The Balanced Series invests at least 25% of its assets
in fixed-income securities. Loomis Sayles has the flexibility to invest the
remaining 75% of the assets of the Balanced Series in either equity or fixed-
income securities, depending on its economic and investment outlook, although
under normal market conditions more than 50% of the total assets of the
Balanced Series will be invested in stocks that Loomis Sayles regards as value
stocks.
 
 Investment Selection
 
Loomis Sayles usually invests approximately 60 to 65% of the total assets of
the Balanced Series in equity securities, although this equity allocation can
shift, depending on Loomis Sayles' longer-term outlook for returns on both
equity and fixed-income securities. When allocating assets, Loomis Sayles
considers, among other things, the valuation level of the general markets, the
valuation level of stocks in the Balanced Series' portfolio, the forecast
earnings growth for those companies, trends in inflation, the level of interest
rates and the expected direction of change in economic growth.
 
 Equity Holdings
 
The Balanced Series' equity holdings generally consist of value stocks with a
minimum market capitalization of $2 billion. When selecting stocks for the
Balanced Series, Loomis Sayles screens all market sectors for stocks that have
below-average price/earnings ratios on next year's earnings. Loomis Sayles then
uses a proprietary quantitative model to review each stock that it believes
will improve its earnings outlook and ranks each stock within its industry
group based on valuation, earnings momentum and balance sheet strength. Stocks
for which Loomis Sayles analysts have positive opinions and which have high
quantitative rankings become leading purchase candidates for the Balanced
Series, at the discretion of the portfolio managers.
 
 Fixed-income Holdings
 
The Balanced Series' fixed-income holdings may consist of a variety of
securities including U.S. Treasury and agency issues, mortgage-backed
securities, asset-backed securities, and corporate bonds. The emphasis,
however, is on corporate bonds. The selection process for corporate bonds is a
bottom-up process in which individual securities are selected from Loomis
Sayles' corporate credit universe of approximately 600 issuers. Specific issues
are selected based upon credit fundamentals, yield spread versus U.S. Treasury
issues and maturity considerations. Holdings are limited to a maximum 5%
position in any one credit issuer, no more than 50% in any one sector (i.e.,
utilities, finance, or industrial bonds) and no
 
                                      B-46
<PAGE>
 
more than 20% in any one industry. Once a security is identified as a possible
purchase candidate, the portfolio managers consider market conditions, supply
and demand, and other economic factors when making a purchase decision.
 
Principal Investment Risks
 
 Equity Securities
 
In general, equity securities are considered more volatile than fixed-income
securities. The prices of equity securities will rise and fall in response to
events that affect entire financial markets or industries (changes in inflation
or consumer demand, for example) and to events that affect particular companies
(news about the success or failure of a new product, for example).
 
Growth Stocks and Value Stocks. The prices of growth stocks may be more
sensitive to changes in current or expected earnings than the prices of other
stocks. The price of value stocks may fall, or simply may not increase very
much, if the market does not agree with the subadviser's view of the value of
the stock.
 
Market Capitalization. The stocks of large capitalization companies do not
always have as much growth potential as smaller and medium capitalization
stocks.
 
 Fixed-income Securities
 
The value of most fixed-income securities generally will rise when interest
rates decline and fall when interest rates rise. Fixed-income securities
involve both CREDIT RISK and MARKET RISK. Some fixed-income securities also
involve the risk that an issuer will repay the principal or repurchase the
security before it matures. If this happens, the holder will no longer receive
any interest on that security. The holder could buy another security, but that
other security might pay a lower interest rate. Also, if the holder paid a
PREMIUM when it bought the security, the holder may receive less from the
issuer than it paid for the security.
   
 When-Issued Securities     
 
Loomis Sayles may purchase WHEN-ISSUED SECURITIES. If a Series has made a
commitment to purchase a when-issued security, the Series is obligated to
purchase that security on the settlement date, which is usually one week to one
month after the purchase commitment. If the value of the security falls (or
rises) before the settlement date, the Series will be exposed to that change in
value, because the price it must pay for the security is fixed at the time of
its purchase commitment. Favorable or unfavorable news about particular issuers
or markets could cause the value of the security to fall (or increase) more
than Loomis Sayles expected, and the Balanced Series may have to pay more (or
less) than it would otherwise have been willing to pay if it had not made the
purchase commitment. The Balanced Series will have cash or cash equivalents in
a segregated account sufficient to pay for any when-issued security at time of
settlement.
 
 
 
CREDIT RISK is the risk that the security's issuer will not pay the interest,
dividends or principal that it has promised to pay.
 
MARKET RISK is the risk that the value of the security will fall because of
changes in market rates of interest or other factors.
 
Some securities pay a higher interest rate than the current market rate. An
investor may have to pay more than the security's principal to compensate the
seller for the value of higher interest rate. This additional payment is a
PREMIUM.
 
A WHEN-ISSUED SECURITY is a security that a buyer commits to purchase on some
future date, when that security is issued (the settlement date). The price of
the when-issued security that the buyer will pay is fixed at the time of the
purchase commitment.

                           Alger Equity Growth Series
 
Principal Investment Strategies
 
Alger invests Equity Growth's assets primarily in growth stocks. Alger will
ordinarily invest at least 65% of Equity Growth's total assets in equity
securities of issues with market capitalization of $1 billion or greater.
 
 Stock Selection
 
Alger seeks out and invests primarily in companies that are traded on domestic
stock exchanges or in the domestic over-the-counter market. The companies Alger
chooses for the portfolio of the Series may still be in the development stage,
may be older companies that appear to be entering a new stage of growth
progress due to factors like management changes or development of new
technologies, products or markets, or may be companies providing products or
services with a high unit volume growth rate. Alger focuses on fundamental
characteristics of individual companies and does not allocate assets based on
specific industry sectors.

                             Capital Growth Series
 
Principal Investment Strategies
   
CGM invests Capital Growth's assets primarily in common stock of large
capitalization U.S. companies whose earnings CGM expects will grow at a faster
rate than the United States economy. When market conditions warrant, however,
CGM may select stocks on the basis of overall economic factors such as the
general economic outlook, the level and direction of interest rates and the
potential impact of inflation. Capital Growth invests primarily in equity
securities of U.S. companies but may also invest in equity securities of
foreign issuers. Over time, Capital Growth has held larger positions in a
smaller number of issuers than many other mutual funds. CGM does not consider
income as a significant factor when selecting investments for Capital Growth.
    
 Stock Selection
 
In general, CGM seeks companies with the following characteristics:
 
  . A well-established record of above-average growth.
 
  . The prospect of maintaining market leadership.
 
  . The potential to benefit from internal revitalization or innovations,
    changes in consumer demand or basic economic forces.
 
Although CGM searches for these types of companies, not every company in which
Capital Growth invests will have all of these characteristics. Rather than
strictly following a growth style, CGM may also invest in attractive value
stocks. In making an investment decision, CGM will generally:
 
  . Use a top-down approach to analyze the overall economic factors that may
    affect a potential investment.
 
  . Thoroughly analyze certain industries and companies, evaluate the
    fundamentals of each and focus on attractively valued companies.
 
  . Purchase a security only after a thorough assessment of all information
    that CGM deems to be relevant at the time of investment.
 
  . Sell a stock if CGM's investment expectations are not being met, if CGM
    identifies better opportunities or if CGM has attained its price
    objective.

harm the performance and liquidity of the Series' investments in those
countries. Additionally, many countries have less stringent financial reporting
requirements than the United States, so it may be difficult to obtain
information to evaluate the business potential of foreign issuers.     
   
Regional and National Risk. News and events unique to particular regions and
foreign countries will affect non-U.S. markets and issuers. These same events
may not affect the U.S. economy or similar issuers located in the United States
in the same manner. As a result, movements in the prices of foreign securities
may not correlate with the prices of U.S. securities.     
   
Currency Risk. As many investments in foreign countries are denominated in
foreign currencies, changes in the value of those countries' currencies
relative to the U.S. dollar may affect the value of those investments. These
changes may occur in response to events unrelated to the value of the security
in the issuer's home country.

                           Davis Venture Value Series
 
Principal Investment Strategies
   
Davis Selected invests Venture Value's assets primarily in U.S. common stocks
of companies that have a market capitalization of at least $5 billion and that
Davis Selected believes are of high quality and are selling at attractive
prices. Davis Selected generally selects stocks with the intention of holding
them for the long term. Davis Selected believes that managing risk is the key
to delivering superior long-term investment results; therefore, it considers
how much could potentially be lost on an investment before considering how much
might be gained.     
 
 Stock selection
 
Davis Selected has developed a list of ten characteristics that it believes
allow companies to sustain long-term growth and minimize risks to enhance their
potential for superior long-term returns. Although few companies exhibit all
ten characteristics, Davis Selected searches for companies that possess:
 
  . Excellent management.
 
  . Managers who own stock in their own company.
 
  . Strong returns on investments of an issuer's capital.
 
  . A lean expense structure.
 
  . A dominant or growing market share in a growing market.
 
  . A proven record as an acquirer.
 
  . A strong balance sheet.
 
  . Products or services that are not likely to become obsolete.
 
  . Successful international operations.
 
  . Innovation in all aspects of operations.
 
Davis Selected does not have particular allocation strategies, and emphasizes
individual stock selection rather than industry sectors. Davis Selected relies
heavily on its evaluation of the management of potential investments, and will
ordinarily visit the managers at their place of business to gain insight into
the relative value of different companies.

of which are quoted in foreign currencies). In addition, GSAM may invest up to
35% of Midcap Value's total assets in fixed-income securities, including up to
10% of its total assets in high yield debt. Midcap Value does not focus on
dividend income.     
 
 Stock Selection
 
GSAM evaluates securities using a value approach, employing fundamental
analysis to identify securities that are, in its view, underpriced relative to
a combination of such companies' long-term earning prospects, growth potential,
future cash flows and dividend-paying ability. GSAM may also invest Midcap
Value's assets in securities of companies that have experienced difficulties
and that GSAM believes are available at attractive prices. Factors that GSAM
considers when evaluating a company as a potential investment include:
 
  . High quality of the company's core business.
 
  . The company's competitiveness and market position.
 
  . The degree of regulation in markets in which the company operates.
 
  . A record of success by the company's management team.
 
  . The level of the company's financial leverage.
 
  . A sustainable return on capital invested in the company's business.
 
Principal Investment Risks
 
 Equity Securities
 
In general, equity securities are considered more volatile than fixed-income
securities. The prices of equity securities will rise and fall in response to
events that affect entire financial markets or industries (changes in inflation
or consumer demand, for example) and to events that affect particular companies
(news about the success or failure of a new product, for example).
 
Growth Stocks and Value Stocks. The prices of growth stocks may be more
sensitive to changes in current or expected earnings than the prices of other
stocks. The price of value stocks may fall, or simply may not increase very
much, if the market does not agree with the subadviser's view of the value of
the stock.
 
                                      B-54
<PAGE>
 
Market Capitalization. The stocks of smaller capitalization companies involve
potentially greater risks and higher volatility than those of larger, more
established companies.
 
 Fixed-income Securities
 
The value of most fixed-income securities generally will rise when interest
rates decline and fall when interest rates rise. Fixed-income securities
involve both CREDIT RISK and MARKET RISK. Some fixed-income securities also
involve the risk that an issuer will repay the principal or repurchase the
security before it matures. If this happens, the holder will no longer receive
any interest on that security. The holder could buy another security, but that
other security might pay a lower interest rate. Also, if the holder paid a
PREMIUM when it bought the security, the holder might receive less from the
issuer than it paid for the security.
 
 High yield debt
 
High yield debt has a higher credit risk and market risk than investment grade
fixed-income securities. Issuers could have high credit risk for many reasons,
including problems with product development or distribution, reductions in
market share or overall sales, competition in their markets or a high degree of
LEVERAGE. High yield debt has higher market risk for a variety of reasons,
including greater sensitivity to interest rate changes and economic downturns,
and the difficulty some issuers may have when trying to obtain additional
financing. Also, high yield debt may be difficult to value, and if other
investors believe that a certain issuer's securities are overvalued, the holder
may be unable to sell those securities for what it believes is an adequate
amount.
 
 Foreign Securities
 
In addition to the risks associated with securities generally, foreign
securities present additional risks.
 
Regulation and Access to Information. Changes in foreign countries' laws may
harm the performance and liquidity of the Series' investments in those
countries. Additionally, many countries have less stringent financial reporting
requirements than the United States, so it may be difficult to obtain
information to evaluate the business potential of foreign issuers.
 
Regional and National Risk. News and events unique to particular regions and
foreign countries will affect non-U.S. markets and issuers. These same events
may not affect the U.S. economy or similar issuers located in the United States
in the same manner. As a result, movements in the prices of foreign securities
may not correlate with the prices of U.S. securities.
 
Currency Risk. As many investments in foreign countries are denominated in
foreign currencies, changes in the value of those countries' currencies
relative to the U.S. dollar may affect the value of those investments. These
changes may occur in response to
 
CREDIT RISK is the risk that the security's issuer will not pay the interest,
dividends or principal that it has promised to pay.
 
MARKET RISK is the risk that the value of the security will fall because of
changes in market rates of interest or other factors.
 
Some securities pay a higher interest rate than the current market rate. An
investor may have to pay more than the security's principal to compensate the
seller for the value of the higher interest rate. This additional payment is
called a PREMIUM.
 
LEVERAGE in this context is a measure of how much a company has borrowed in
relation to its shareholders' equity.

A FORWARD CONTRACT is an agreement to buy or sell securities or currencies on a
specified future date at a specific price.
 
A FUTURES CONTRACT is an obligation to buy or sell an asset on a specified
future date, or to pay or receive money based on the value of some securities
index or currency or interest rate on a specified future date. Typically,
futures contracts are traded on an exchange (rather than entered into between
two parties). Futures contracts are one kind of DERIVATIVE.

events unrelated to the value of the security in the issuer's home country.
GSAM may use certain techniques, such as FORWARD CONTRACTS or FUTURES
CONTRACTS, to manage these risks. However, GSAM cannot assure that these
techniques will be effective.
 
 Forward Contracts and Futures
 
The Series may attempt to avoid the risk of an unfavorable shift in currency
rates by entering into forward contracts or buying or selling futures contracts
or options on futures contracts. The Series may also purchase futures contracts
(or options on futures contracts) to maintain exposure to the broad equity
markets or, in some cases, to increase overall returns for non-hedging
purposes.
 
Forward contracts. By entering into a forward contract, Midcap Value is giving
up the potential gains (and avoiding the potential losses) that may occur if
the actual exchange rate on the specified date is different from the exchange
rate established in the contract.
 
Futures contracts. If the price of a futures contract changes more than the
price of the security or index on which the contract is based, Midcap Value
could make or lose more money than if it had invested directly in the
underlying security or index. This added volatility increases the risk of these
investments. In addition, investors may be unwilling to buying or selling
futures contracts under some market conditions. If this happens, GSAM might not
be able to close out futures transactions without incurring substantial losses.
 
 Emerging Markets
 
Midcap Value may invest in emerging markets, which are generally located in the
Asia-Pacific Region, Eastern Europe, Latin and South America and Africa. In
addition to the risks of foreign securities described above (which are
potentially greater for emerging markets securities than for other foreign
securities), emerging markets securities may be subject to other risks,
including increased risks of reduced liquidity, high inflation rates, political
uncertainty, high administrative and regulatory costs, repatriation of income
and less advantageous investment terms relative to foreign nationals.
 
Portfolio Management
   
As of December 31, 1998, GSAM managed approximately $195 billion in assets.
GSAM is located at One New York Plaza, New York, New York 10004.     
 
Paul D. Farrell is the manager of a team of portfolio managers (the "Midcap
Value Team") that makes the day-to-day investment decisions for Midcap Value.
Mr. Farrell joined GSAM in 1991 and in 1998 became responsible for managing the
Midcap Value Team.
   
Eileen A. Aptman, Matthew B. McLennan, and Karma Wilson, all of whom are Vice
Presidents of GSAM, constitute the Midcap Value Team, and have served as
portfolio managers of Midcap Value

in 1995. From 1994 to 1995 he worked in the Investment Banking Division of
Goldman Sachs in Australia. Ms. Wilson joined GSAM in 1994. Prior to 1994 she
was an investment analyst with Bankers Trust Australia Ltd.
   
During the year ended December 31, 1998, Midcap Value paid 0.73% of its average
net assets in investment advisory fees and its total operating expenses were
0.88% of such assets.

                         Loomis Sayles Small Cap Series
 
Principal Investment Strategies
   
Loomis Sayles, under normal market conditions, will invest at least 65% of
Small Cap's total assets in equity securities of U.S. companies with market
capitalizations that fall within the capitalization range of those companies
constituting the Russell 2000 Index. Small Cap invests in both value and growth
stocks.     
 
 Stock Selection
 
Loomis Sayles begins with a universe of approximately 3000 companies that
generally fall within the market capitalization range of the Russell 2000
Index. Small Cap's portfolio managers, with the assistance of Loomis Sayles'
research analysts, conduct fundamental analysis on these companies to identify
companies that Loomis Sayles believes have strong earnings prospects and growth
potential and that appear to the portfolio managers to be the most undervalued
in the current market. Finally, Loomis Sayles builds a diversified portfolio
across many economic sectors so that Small Cap is partially protected against
the inherent volatility of small capitalization companies. Portfolio managers
and research analysts regularly monitor the performance of the stocks held by
Small Cap and the fundamentals of the companies that have issued those stocks.

In general, equity securities are considered more volatile than fixed-income

the stock.
 
Market Capitalization. The stocks of small capitalization companies may
underperform the broad equity markets and may be more volatile than other
stocks.
 
Real Estate Investment Trusts (REITs). One category of equity securities in
which Small Cap invests are REIT's. REITs are generally categorized as equity
REITs or mortgage REITs, although some REITs have characteristics of both
classifications. Equity REITs invest directly in real property and receive
income from rent collection and sale of those properties. These REITs may
decline in value when the property they own declines in value. Mortgage REITs
invest in real estate mortgages and receive income
 
                                      B-58

from interest payments on those mortgages. These REITs are particularly subject
to CREDIT RISK and MARKET RISK, although equity REITs are also sensitive to
market risk.
 
Portfolio Management
   
Loomis Sayles has been in the investment management business since 1926. As of
December 31, 1998, Loomis Sayles managed approximately $64 billion in assets.
Loomis Sayles' address is One Financial Center, Boston, Massachusetts 02110.
    
Christopher R. Ely and Jeffrey C. Petherick are the lead Portfolio Managers of
Small Cap. The other Portfolio Managers are Mary C. Champagne, Philip C. Fine
and David L. Smith.
   
Mr. Petherick, a Vice President of Loomis Sayles, has managed (or co-managed)
the Series since its inception and joined Loomis Sayles more than five years
ago. Mr. Ely, a Vice President of Loomis Sayles, has co-managed the Series
since April 1999 and joined Loomis Sayles in 1996. Before joining Loomis
Sayles, Mr. Ely was a Senior Vice President and portfolio manager at Keystone
Investment Management Company, Inc. Ms. Champagne, a Vice President of Loomis
Sayles, has co-managed the Series since 1995 and joined Loomis Sayles more than
five years ago. Mr. Fine, a Vice President of Loomis Sayles, has co-managed the

During the year ended December 31, 1998, Small Cap paid 1.00% of its average
net assets in investment advisory fees and its total operating expenses were
1.00% of such assets.     

CREDIT RISK is the risk that the security's issuer will not pay the interest,

                              MFS Investors Series
 
Principal Investment Strategies
   
MFS ordinarily invests at least 65% of the total assets of the Investors Series
in equity securities. Although the Series may invest in companies of any size,
the Series focuses on companies with large market capitalizations (greater than
$5 billion) that MFS believes have sustainable growth prospects and attractive
valuations based on current and expected earnings or cash flow. MFS may also
invest a substantial portion of the assets of the Investors Series in foreign
securities.     
 
 Stock Selection
 
MFS uses a bottom-up, as opposed to a top-down, investment style in managing
the Investors Series. This means that MFS selects securities based upon
fundamental analysis performed by the portfolio manager and MFS' large group of
equity research analysts.

Principal Investment Strategies
 
MFS invests at least 80% of the total assets of the Research Managers Series in
equity securities. The Series invests primarily in companies that MFS believes
possess better than average prospects for long-term growth and attractive
valuations. MFS may also invest up to 20% of the net assets of the Series in
foreign securities.
 
 Stock Selection
 
A committee of investment research analysts selects portfolio securities for
the Research Managers Series. This committee includes investment analysts
employed by MFS and MFS International (U.K.) Limited, a wholly owned subsidiary
of MFS. The committee first allocates assets among various industries.
Individual analysts are then responsible for selecting what they view as the
securities best suited to meet the investment objective of the Series from
within their assigned industry responsibility. Analysts focus on companies that
they believe have favorable prospects for long-term growth, attractive
valuations based on current and expected earnings or cash flow, dominant or
growing market share and superior management. The Series may invest in
companies of any size and its investments may include securities traded on
securities exchanges or in the over-the-counter markets.

                       Westpeak Growth and Income Series
 
Principal Investment Strategies
 
Westpeak is not limited to either the growth or value style of investing.
Westpeak sometimes invests more of Growth and Income's assets in value stocks,
and sometimes invests more heavily in growth stocks. Growth and Income invests
primarily in stocks of large capitalization U.S. companies, such as those
included in the S&P 500 Index, but it may also invest such assets in securities
of smaller companies, such as those included in the Russell 1000 Index.
Westpeak emphasizes individual stock selection rather than targeting particular
industries or sectors which it believes may outperform other sectors.
 
 Stock Selection
 
Westpeak uses the following procedure to select stocks for Growth and Income:
 
  . Westpeak collects extensive amounts of information on a large universe of
    companies.
 
  . Westpeak then develops a profile of characteristics that Westpeak
    believes Growth and Income's portfolio should possess to best achieve the
    investment objective of the Series. Westpeak considers many factors when
    developing this profile, including historic earnings and other
    fundamentals, market expectations for corporate earnings and overall
    growth prospects. Westpeak regularly revises the profile in response to
    changing market conditions.
 
  . Westpeak then ranks each of the companies in a variety of categories
    based on the information it has collected about those companies.
 
  . Westpeak then uses fundamental research, quantitative analysis and
    judgment to select stocks that, when assembled in a single portfolio,
    will most closely replicate the profile Westpeak builds for Growth and
    Income.

During the year ended December 31, 1998, Stock Index paid 0.25% of its average
net assets in investment advisory fees and its total operating expenses were
0.37% of such assets.

               Morgan Stanley International Magnum Equity Series
 
Principal Investment Strategies
   
MSAM invests International Equity's assets in a diversified portfolio of stocks
of foreign issuers domiciled in EAFE countries. MSAM may also invest up to 5%
of the Series' total assets in non-EAFE countries. MSAM seeks to achieve
superior long-term returns by creating a diversified portfolio of stocks that
MSAM believes are undervalued. To achieve this goal, MSAM implements a
combination of strategic geographic asset allocation and fundamental, value-
oriented stock selection implemented by regional experts around the globe.     
 
 Stock Selection
 
MSAM evaluates potential investments for International Equity in several steps.
 
The New York-based portfolio management team decides upon the appropriate
allocation of International Equity's assets among Europe, Japan and developed
Asia (including Australia/New Zealand). This regional allocation is based on a
variety of factors, including relative valuations, earnings expectations,
macroeconomic factors and input from the regional stock selection teams and
from MSAM's Asset Allocation Committee, which is made up of several of MSAM's
most senior investment officers.
   
Once the allocations to Europe, Asia and Japan have been determined, overseas
investment teams in London (for European stocks), Tokyo (for Japanese stocks)
and Singapore (for Asian stocks) decide which stocks International Equity
should purchase in their respective geographic regions. These three regional
portfolio management teams look for stocks that they believe to be undervalued
by the market. The regional specialists analyze each company's finances,
products and management, typically meeting with a company's management before
its stock is purchased.     
 
Principal Investment Risks
 
 Equity Securities
 
In general, equity securities are considered more volatile than fixed-income
securities. The prices of equity securities will rise and fall in response to
events that affect entire financial markets or industries (changes in inflation
or consumer demand, for example) and to events that affect particular companies
(news about the success or failure of a new product, for example).
 
Growth Stocks and Value Stocks. The prices of growth stocks may be more
sensitive to changes in current or expected earnings than the prices of other
stocks. The price of value stocks may fall, or simply may not increase very
much, if the market does not agree with the subadviser's view of the value of
the stock.
 
 Foreign Securities
 
In addition to the risks associated with equity securities generally, foreign
securities present additional risks.
 
Regulation and Access to Information. Changes in foreign countries' laws may
harm the performance and liquidity of the Series' investments in those
countries.
 
Additionally, many countries have less stringent financial reporting
requirements than the United States, so it may be difficult to obtain
information to evaluate the business potential of foreign issuers.
 
Regional and National Risk. News and events unique to particular regions and
foreign countries will affect non-U.S. markets and issuers. These same events
may not affect the U.S. economy or similar issuers located in the United States
in the same manner. As a result, movements in the prices of foreign securities
may not correlate with the prices of U.S. securities.
 
                                      B-66
<PAGE>
 
Currency Risk. As many investments in foreign countries are denominated in
foreign currencies, changes in the value of those countries' currencies
relative to the U.S. dollar may affect the value of those investments. These
changes may occur in response to events unrelated to the value of the security
in the issuer's home country. MSAM may use certain techniques, such as FORWARD
CONTRACTS or FUTURES CONTRACTS, to manage these risks. However, MSAM cannot
assure that these techniques will be effective.
 
 Forward Contracts and Futures
 
The Series may attempt to avoid the risk of an unfavorable shift in currency
rates by entering into forward contracts or buying or selling futures contracts
or options on futures contracts. The Series may also purchase futures contracts
(or options on futures contracts) to maintain exposure to the broad equity
markets.
 
Forward contracts. By entering into a forward contract, International Equity is
giving up the potential gains (and avoiding the potential losses) that may
occur if the actual exchange rate on the specified date is different from the
exchange rate established in the contract.
 
Futures contracts. If the price of a futures contract changes more than the
price of the security or index on which the contract is based, International
Equity could make or lose more money than if it had invested directly in the
underlying security or index. This added volatility increases the risk of these
investments. In addition, investors may be unwilling to buy or sell futures
contracts under some market conditions. If this happens, International Equity
might not be able to close out futures transactions without incurring
substantial losses.
 
Portfolio Management
   
As of December 31, 1998, MSAM, together with its affiliated institutional asset
management companies, managed approximately $163.4 billion in assets. MSAM's
address is 1221 Avenue of the Americas, New York, New York 10020.     
   
Francine J. Bovich, a Managing Director of Morgan Stanley & Co. Incorporated
and MSAM, joined MSAM in 1993. She is primarily responsible for managing
International Equity's portfolio. Previously, Ms. Bovich was a Principal and
Executive Vice President of Westwood Management Corp., a registered investment
adviser. Barton Biggs, Managing Director of MSAM, heads MSAM's Asset Allocation
Committee.     
   
During the year ended December 31, 1998, International Equity paid 0.90% of its
average net assets in investment advisory fees and its total operating expenses
were 1.30% of such assets.     
 
A FORWARD CONTRACT is an agreement to buy or sell securities or currencies on a
specified future date at a specific price.
 
A FUTURES CONTRACT is an obligation to buy or sell an asset on a specified
future date, or to pay or receive money based on the value of some securities
index or currency or interest rate on a specified future date. Typically,
futures contracts are traded on an exchange (rather than entered into between
two parties). Futures contracts are one kind of DERIVATIVE.
 
A DERIVATIVE is a financial instrument whose value is based on (derived from)
changes in the value of something else, such as a currency, an interest rate or
a security.

               Section IV--Other Information About The Fund     
 
Investment Advisory Services
 
 All Series except Capital Growth
   
NEIM was organized in 1994 by New England Financial to serve as the investment
adviser of the Fund. NEIM is located at 501 Boylston Street, Boston,
Massachusetts 02116. Each Series pays NEIM an investment advisory fee. NEIM has
contracted with subadvisers to make the day-to-day investment decisions for
these Series and NEIM pays each subadviser's fees. NEIM also provides a full
range of administrative and accounting services to these Series.     
 
 Capital Growth
   
CGM makes the day-to-day investment decisions for Capital Growth and has
arranged for NEIM to provide administrative and accounting services to the
Series. CGM receives an investment advisory fee from the Fund for its services
to Capital Growth. CGM has subcontracted with and pays NEIM for providing
administrative and accounting services to Capital Growth.     
   
Adviser/Subadviser Relationship     
   
The Fund has received an exemptive order from the Securities and Exchange
Commission that permits NEIM to enter into new subadvisory agreements with
either a current or a new subadviser that is not an affiliate of the Fund or
NEIM, without obtaining shareholder approval. The Fund's Board of Trustees must
approve any new subadvisory agreements under this order, and the Fund must
comply with certain other conditions.     
   
The exemptive order also permits the Fund to continue to employ an existing
subadviser without shareholder approval after events that would otherwise cause
an automatic termination of a subadvisory agreement (and the need for a
shareholder vote). This continuation must be approved by the Board of Trustees.
The Fund will notify shareholders of any subadviser changes and any other event
of which notification is required under the order.     
       
Purchase and Redemption of Shares
       
The Separate Accounts may purchase or redeem shares of a Series on each day
that the New York Stock Exchange (the "NYSE") is open for business. The Fund
sells and redeems shares of each Series at the net asset value for that Series
calculated at the close of regular trading on the NYSE, ordinarily 4:00 p.m.
Eastern time each day. These transactions are made on the same day that the
purchase order or redemption request is received by the Fund from the Separate
Accounts. No transactions occur on those days that the NYSE is closed for
trading.
 
The Fund may suspend the right of redemption for any Series and may postpone
payment for any period when the NYSE is closed for other than weekends or
holidays. The Fund may also postpone payment when trading on the NYSE is
restricted or during an emergency in which disposing of securities or fairly
determining the value of net assets is impracticable. The Fund may also suspend
redemption rights when the SEC permits such suspension for the protection of
investors.
 
Share Valuation and Pricing
 
 Net Asset Value
 
Each Series determines the net asset value of its shares as of the close of
regular trading on each day that the NYSE is open. The net asset value per
share for each Series is calculated by dividing the Series' total net assets by
its number of outstanding shares.
 
                                      B-68
<PAGE>
 
   
Because foreign exchanges are not always closed at the same time that the NYSE
is closed, the price of securities primarily traded on foreign exchanges may
increase or decrease when the NYSE is closed. Therefore, the net asset value of
Series that hold these securities may change on days that Separate Accounts
will not be able to purchase or redeem Fund shares.     
       
 Securities Valuation
 
The entire Money Market investment portfolio and any fixed-income securities
with remaining maturities of 60 days or less held by any other Series are
valued at amortized cost. Other portfolio securities of each Series normally
are valued at market value. On the rare occasions when no current market value
is available for a portfolio security, the Fund's Board of Trustees is
responsible for making a good faith determination of fair value, although the
Board has delegated responsibility for day-to-day fair value calculations to
CGM and the subadvisers of the Series.
   
Year 2000     
   
The Fund depends on the smooth functioning of computer systems for both its
internal operations and overall investment performance. Many computer systems
in use today cannot distinguish between the year 1900 and the year 2000. If
computer systems fail to process information properly relating to the year
2000, the Fund's operations and services could be harmed, and the securities in
which the Fund invests may not perform as well as they otherwise might.     
   
NEIM, CGM, the subadvisers and certain other service providers to the Series
have reported that each expects to modify its systems, as necessary, prior to
January 1, 2000 to address the so-called "year 2000 problem." However, there
can be no assurance that the problems will be corrected, and Fund operations
and services provided to shareholders may be affected. Although the subadvisers
to certain of the Series may consider the year 2000 problem when evaluating
investment opportunities, there can be no assurance that improperly functioning
computers will not affect specific issuers or broad markets.     
 
Dividends and Capital Gain Distributions
 
 Money Market
 
Money Market declares its net investment income daily and pays these amounts
monthly as a dividend. Money Market does not expect to realize any long-term
capital gains, but if it does, these gains will be distributed once a year.
 
 Other Series
 
Currently, each Series other than Money Market annually pays as dividends
substantially all net investment income (including any short-term capital
gains). These Series also annually distribute all net realized capital gains,
if any, after offsetting any capital loss carryovers. Each Series, other than
Money Market, may pay dividends from net investment income more or less often
if the Fund's Board of Trustees deems it appropriate and if such change would
not cause such Series to fail to qualify as regulated investment company under
the Internal Revenue Code.
 
Federal income tax law requires each Series to distribute prior to calendar
year-end virtually all of its ordinary income for such year. Also, each Series
must distribute virtually all of its capital gain net income realized but not
previously distributed in the one-year period ending October 31 (or December
31, if the Series so elects) of such year.
 
Dividends and distributions of each Series are automatically reinvested in
additional shares of that Series.
 
Taxes
 
Each Series is a separate entity for federal income tax purposes and intends to
qualify as a regulated investment company under the Internal Revenue Code. So
long as a Series distributes all of its net investment income and net capital
gains to its shareholders, the Series itself does
 
                                      B-69
<PAGE>
 
not pay any federal income tax. Although each Series intends to operate so that
it will have no federal income tax liability, if any such liability is
incurred, the investment performance of such Series will be adversely affected.
In addition, Series investing in foreign securities and currencies may be
subject to foreign taxes. These taxes could reduce the investment performance
of such Series.
 
In order for contract holders to receive the favorable tax treatment that is
generally available to holders of variable annuity and variable life contracts,
the separate accounts underlying such contracts, as well as the Series in which
such accounts invest, must meet certain diversification requirements. Each
Series intends to comply with these requirements. If a Series does not meet
such requirements, income allocable to the variable annuity and variable life
contracts, including accumulated investment earnings, would be taxable
immediately to the holders of such contracts. For a description of the tax
consequences for variable annuity and variable life contract owners, see the
prospectus for those contracts.

                              Financial Highlights
   
The financial highlights table is intended to help you understand each Series'
financial performance for the past 5 years (or the life of the Series, for
these Series that have not been in existence for 5 years). Certain information
reflects financial results for a single share of the relevant Series. The total
returns in the table represent the rate that an investor would have earned (or
lost) on an investment in the Series (assuming reinvestment of all dividends
and distributions). The information for the years ended December 31, 1997 and
1998 has been audited by Deloitte & Touche, LLP, whose report for 1998, along
with the Fund's financial statements, are included in the annual report which
is available upon request. Prior to 1997, PriceWaterhouseCoopers L.L.P. acted
as the Fund's independent accountants and provided reports which accompanied
the financial statements for those periods.

    taxes, or extraordinary expenses) of the Series in excess of an annual
    expense limit of 0.85% (through December 31, 1995) of the Series' average
    daily net assets, subject to the obligation of the Series to repay NEIM
    such expenses in future years, if any, when the Series' operating expenses
    fall below this stated expense limit; such deferred expenses may be charged
    to the Series in a subsequent year to the extent the charge does not cause
    the total operating expenses in such subsequent year to exceed the 0.85%
    expense limit; provided, however, that the Series is not obligated to repay
    any expense paid by NEIM more than two years after the end of the fiscal
    year in which such expense was incurred. Beginning January 1, 1996, the
    annual operating expense limit was increased to 0.90% of the Series'
    average daily net assets.

                       INVESTMENT OBJECTIVES AND POLICIES

    
  The investment objectives and principal investment strategies of each Series
(collectively and individually the "Series") of New England Zenith Fund (the
"Fund") are set forth in Sections II and III of the Prospectus.  There can be no
assurance that a Series will achieve its objective.  The investment policies of
each Series set forth in the Prospectus and in this Statement of Additional
Information may be changed without shareholder approval, except for any policy
as to which the Prospectus or this Statement of Additional Information
explicitly indicates that such approval is required, and except for the
investment objectives of Money Market, Bond Income, Capital Growth, Growth and
Income, Stock Index, Managed and Small Cap, which are fundamental investment
objectives.      

  The terms "shareholder approval" and "approval of a majority of the
outstanding voting securities," as used in the Prospectus and this Statement of
Additional Information, mean, with respect to a Series, approval by the lesser
of (i) 67% of the shares of the Series represented at a meeting at which more
than 50% of the outstanding shares of such Series are represented or (ii) more
than 50% of the outstanding shares of such Series.

Morgan Stanley International Magnum Equity Series

  International Equity seeks long-term capital appreciation through investment
primarily in international equity securities. The production of any current
income is incidental to this objective. Morgan Stanley Asset Management ("MSAM")
is subadviser to International Equity.  On December 1, 1998, Morgan Stanley
Asset Management Inc. changed its name  to Morgan Stanley Dean Witter Investment
Management Inc. but continues to do business under certain circumstances
(including as subadviser to International Equity) using the name Morgan Stanley
Asset Management.

  MSAM seeks to achieve International Equity's investment objective by
investing the Series' assets primarily in common and preferred stocks,
convertible securities, rights or warrants to purchase common stocks and other
equity securities of non-U.S. issuers, in accordance with the EAFE country (as
defined below) weightings determined by MSAM. The equity securities in which the
Series may invest may be denominated in any currency.

  The countries in which the Series will primarily invest are those comprising
the Morgan Stanley Capital International EAFE Index (the "EAFE Index"), which
include Australia, Japan, New Zealand, most nations located in Western Europe
and certain developed countries in Asia, such as Hong Kong and Singapore (each
an "EAFE country," and collectively the "EAFE countries").  The Series may
invest up to 5% of its assets in non-EAFE countries.  Under normal
circumstances, at least 65% of the total assets of the Series will be invested
in equity securities of issuers in at least three different EAFE countries.

  Although the Series intends to invest primarily in equity securities listed
on a stock exchange in an EAFE country, the Series may invest without limit in
equity securities that are traded over the counter or that are not admitted to
listing on a stock exchange or dealt in on a regulated market.  As a result of
the absence of a public trading market, such securities may pose liquidity
risks.
    
  MSAM uses a combination of strategic geographic asset allocation and 
fundamental, value-oriented stock selection. Regional allocation decisions are 
based on a variety of factors, including relative valuations, earnings 
expectations, macroeconomic factors and input from the regional stock selection
teams and from MSAM's Asset Allocation Committee, which is made up of several of
MSAM's most senior investment officers. MSAM develops projections that are used
to establish regional allocation strategies. Within these regional allocations,
MSAM then selects equity securities among issuers of a region.      

  MSAM's approach in selecting among equity securities within a region comprised
of EAFE countries is oriented towards individual stock selection and is value
driven. MSAM identifies those equity securities which it believes to be
undervalued. MSAM's regional specialists analyze each company's finances,
products and management, typically meeting with a company's management before
purchasing that company's stock.

  Although the Series anticipates being fully invested in equity securities of
EAFE countries, the Series may invest, under normal circumstances for cash
management purposes, up to 35% of its total assets in certain short-term (less
than twelve months to maturity) and medium -term (not greater than five years to
maturity) debt securities or hold cash.

  Although the Series' objective is long-term capital appreciation, it
frequently sells securities to reflect changes in market, industry or individual
company conditions or outlook even though it may only have held those securities
for a short period. 

                                      -3-

As a result of these policies, the Series, under certain market conditions, may
experience high portfolio turnover, although specific portfolio turnover rates
are impossible to predict. In recent years, the portfolio turnover rate of the
Series has fluctuated considerably as a result of strategic shifts in portfolio
holdings designed to maintain an optimum portfolio structure in view of general
market conditions and movements in individual stock prices. After taking over
the portfolio on May 1, 1997, MSAM restructured the portfolio through a program
trade. Brokerage costs associated with such trade did not exceed more than 2% of
the Series' average net asset value.

Alger Equity Growth Series

   Equity Growth's investment objective is to seek long-term capital
appreciation.  The Series' assets will be invested primarily in a diversified,
actively managed portfolio of equity securities, primarily of companies having a
total market capitalization of $1 billion or greater.  These companies may still
be in the developmental stage, may be older companies that appear to be entering
a new stage of growth progress, or may be companies providing products or
services with a high unit volume growth rate.

   The Series' subadviser, Fred Alger Management, Inc. ("Alger Management"),
seeks to achieve its objective by investing in equity securities, such as common
or preferred stocks or securities convertible into or exchangeable for equity
securities, including warrants and rights.  Except during temporary defensive
periods, the Series invests at least 65% of its total assets in equity
securities of companies that, at the time of purchase of the securities, have
total market capitalization of $1 billion or greater; the Series may invest up
to 35% of its total assets in equity securities of companies that, at the time
of purchase, have total market capitalization of less than $1 billion.  The
Series anticipates that it will invest primarily in companies whose securities
are traded on domestic stock exchanges or in the over-the-counter market.

   The Series may invest in bank and thrift obligations, obligations issued or
guaranteed by the U.S. Government or by its agencies or instrumentalities,
foreign bank obligations and obligations of foreign branches of domestic banks,
and variable rate master demand notes.

   The Series (with respect to 35% of its total assets) may also purchase money
market instruments and repurchase agreements.  With respect to 15% of its net
assets, the Series may purchase restricted securities, including Rule 144A
securities, and  enter into short sales "against the box."

  The Series may lend securities it owns so long as such loans do not exceed
33 1/3% of the Series' total assets.

  Although Equity Growth's objective is long-term capital appreciation, it
frequently sells securities to reflect changes in market, industry or individual
company conditions or outlook even though it may only have held those securities
for a short period.  As a result of these policies, the  Series, under certain
market conditions, may experience high portfolio turnover, although specific
portfolio turnover rates are impossible to predict.  In recent years, the
portfolio turnover rate of the Series has fluctuated considerably as a result of
strategic shifts in portfolio holdings designed to maintain an optimum portfolio
structure in view of general market conditions and movements in individual stock
prices.

Capital Growth Series

   Capital Growth seeks long-term growth of capital through investment primarily
in equity securities of companies whose earnings are expected to grow at a
faster rate than the United States economy.  Most of the Series' investments are
normally in common stocks, although the Series may invest in any type of equity
securities.  Equity securities include common stocks and securities convertible
into common stocks.  Equity securities are volatile investments, subject to
price declines as well as advances, and involve greater risks than some other
investment media.

  As disclosed in the Prospectus, Capital Growth seeks to attain its investment
objective of long-term growth of capital through investment primarily in equity
securities of companies whose earnings are expected to grow at a faster rate
than the United States economy.  The selection of common stocks for  Capital
Growth's investment portfolio is based on the assessment of the Series' adviser,
Capital Growth Management Limited Partnership ("CGM"), that the common stock is
attractively priced relative to its earnings and growth potential.

  The Series does not consider current income as a significant factor in
selecting its investments.  However, during periods when management considers
that economic or market conditions make it desirable, the Series may take a
defensive position by investing a substantial portion of its assets in cash or
fixed-income securities (bonds, notes and money market instruments).  No
estimate can be made as to when or for how long the Series will employ such
defensive strategies; however, in the past, such periods have been as long as
one year.

  The Series does not currently intend to invest in restricted securities,
options or warrants although, subject to its investment restrictions, it may do
so in the future.  See "Investment Restrictions."

  Although the Series' objective is long-term capital growth, it frequently
sells securities to reflect changes in market, industry or individual company
conditions or outlook even though it may only have held those securities for a
short period. As a result of these policies, the Series, under certain market
conditions, may experience high portfolio turnover, although specific portfolio
turnover rates are impossible to predict.  In recent years, the portfolio
turnover rate of the Series has fluctuated considerably as a result of strategic
shifts in portfolio holdings designed to maintain an optimum portfolio structure
in view of general market conditions and movements in individual stock prices.

Davis Venture Value Series

  Venture Value's investment objective is growth of capital.  The Series seeks
to achieve its objective by investing primarily in domestic common stocks that
its subadviser, Davis Selected Advisers, L.P. ("Davis Selected"), believes have
capital growth potential due to factors such as undervalued assets or earnings
potential, product development and demand, favorable operating ratios, resources
expansion, management abilities, reasonableness of market price, and favorable
overall business prospects.  The Series will generally invest predominantly in
equity securities of companies with market capitalizations of at least $5
billion.  It may also invest in issuers with smaller capitalizations.

   The Series may invest in foreign securities, and may hedge currency
fluctuation risks related thereto.  The Series may invest in U.S. registered
investment companies that primarily invest in foreign securities, provided that
no such investment may cause more than 10% of the Series' total assets to be
invested in such companies.  The Series may invest in restricted securities,
which may include Rule 144A securities.

   The Series may write covered call options on its portfolio securities, but
currently intends to write such options only to the extent that less than 5% of
its net assets would be subject to the options.

   The Series may lend securities it owns so long as such loans do not exceed 5%
of the Series' net assets.


Goldman Sachs Midcap Value Series

   Midcap Value seeks to provide investors with long-term capital appreciation.
Goldman Sachs Asset Management ("GSAM") invests, under normal circumstances,
substantially all of the Series' assets in equity securities and at least 65% of
its total assets in equity securities of companies with public stock market
capitalizations (based upon shares available for trading on an unrestricted
basis)  within the range of the market capitalization of companies constituting
the Russell Midcap Index.  If the capitalization of an issuer increases above or
decreases below this range after purchase of such issuer's securities, the
Series may, but is not required to, sell the securities.  Dividend income, if
any, is an incidental consideration.

   GSAM evaluates securities using a value approach, employing fundamental
analysis to identify securities that are, in its view, underpriced relative to a
combination of such companies' long-term earnings prospects, growth potential,
future cash flows and/or dividend-paying ability.  Consideration will be given
to the business quality of the issuer.  Factors positively affecting GSAM's view
of the quality include the competitiveness and degree of regulation in markets
in which the issuer operates, the existence of a management team with a record
of success, the position of the issuer in markets in which it operates, the
level of the issuer's financial leverage and the sustainable return on capital
invested in the business.  The Series may also purchase securities of companies
that have experienced difficulties and that, in the opinion of GSAM, are
available at attractive prices.

     The Series may invest up to 35% of its total assets in fixed-income
securities, including up to 10% of its total assets in high yield debt (as
defined in "Miscellaneous Investment Practices - Lower Rated Fixed-income
Securities").  In addition, although the Series will invest primarily in
publicly traded U.S. securities, it may invest up to 25% of its total assets in
foreign securities, including up to 15% of its assets in securities of issuers
in emerging markets (as from time to time determined by GSAM) and securities
quoted in foreign currencies.

     The Series may lend securities it owns so long as such loans do not exceed
33 1/3% of the Series' total assets.
 
     The Series may, together with other registered investment companies managed
by GSAM or its affiliates, transfer uninvested cash balances into a single joint
account, the daily aggregate balance of which will be invested in one or more
repurchase agreements.

                                      -5-
<PAGE>
 
     The Series may make short sales "against the box" but will not invest more
than 25% of the Series net assets (determined at the time of the short sale) in
such short sales against the box.

     The Series may engage in active short-term trading to benefit from yield
disparities among different issues of securities or among the markets for equity
securities, or for other reasons.  It is anticipated that the portfolio turnover
rate of the Series will vary from year to year.

Loomis Sayles Small Cap Series


     Small Cap's investment objective is long-term capital growth from
investments in common stocks or their equivalents.

     Loomis, Sayles & Company, L.P. ("Loomis Sayles") manages the Series by
investing primarily in stocks of small capitalization companies with good
earnings growth potential that Loomis Sayles believes are undervalued by the
market. Normally the Series will invest 65% of its assets in companies with
market capitalization, at the time of investment, in the range of the market
capitalization of those companies which make up the Russell 2000 Index, which
have better than average growth rates, below-average price/earnings ratios and
strong balance sheets and cash flow.  Loomis Sayles seeks to build a core small-
cap portfolio of solid growth stocks, but with an additional emphasis on special
situations and turnarounds (companies that have experienced significant business
problems but which Loomis Sayles believes have favorable prospects for
recovery), as well as unrecognized stocks.

     Under unusual market conditions as determined by Loomis Sayles, all or any
portion of the Series may be invested, for temporary, defensive purposes, in
short-term debt instruments or in cash.  In addition, under normal conditions, a
portion of the Series' assets may be invested in short-term assets for liquidity
purposes or pending investment in other securities. Short-term investments may
include U.S. Government securities, certificates of deposit, commercial paper
and other obligations of corporate issuers rated in the top two rating
categories by a major rating agency or, if unrated, determined to be of
comparable quality by the subadviser, and repurchase agreements that are fully
collateralized by cash, U.S. Government securities or high-quality money market
instruments.

MFS Investor Series

     The Investors Series' investment objective is to provide reasonable current
income and long-term growth and income.

     Under normal conditions,  Massachusetts Financial Services Company ("MFS")
will invest at least 65% of the Series' assets in equity securities of companies
that are believed to have long-term prospects for growth and income.

     Consistent with its investment objective and policies described above, the
Series may also invest up to 20% of its net assets in foreign securities
(including emerging market securities) which are not traded on a U.S. exchange.

MFS Research Managers Series

     The Research Managers Series' investment objective is to provide long-term
growth of capital and future income.

     The portfolio securities of the Series are selected by a committee of
investment research analysts.  This committee includes investment analysts
employed by MFS and its affiliates.  The Series' assets are allocated among
industries by the analysts acting together as a group.  Individual analysts are
then responsible for selecting what they view as the securities best suited to
meet the Series' investment objective with their assigned industry
responsibility.

     The Series policy is to invest a substantial proportion of its assets in
equity securities of companies believed to possess better than average prospects
for long term growth.  A small proportion of the assets may be invested in
bonds, short-term obligations, preferred stocks or common stocks whose principal
characteristic is income production rather than growth. Such securities may also
offer opportunities for growth of capital as well as income.  In the case of
both growth stocks and income issues, emphasis is placed on selection on
progressive, well-managed companies.   The Series' non-convertible debt
investments, if any, may consist of "investment grade" securities (rated Baa or
better by Moody's or better by S&P or by Fitch), and, with respect to no more
than 10% of the Series' net assets, securities in the lower rated categories
(rated Ba or 

                                      -6-
<PAGE>
 
lower by Moody's or BB or lower by S&P, by Fitch or by Duff & Phelps) or
securities which the adviser believes to be of similar quality to these lower
rated securities (commonly known as "junk bonds"). For a description of bond
ratings, see Appendix A to this SAI.

  Consistent with this investment objective and policies described above, the
Series may also invest up to 20% of its net assets in foreign securities
(including emerging market securities) which are not traded on a U.S. exchange.



Westpeak Growth and Income Series

   As disclosed in the Prospectus, Growth and Income seeks long-term total
return (capital appreciation and dividend income) through investment in equity
securities, both in securities that the Series' subadviser, Westpeak Investment
Advisors, L.P. ("Westpeak"), believes are undervalued ("value" style) and
securities of companies that Westpeak believes have growth potential ("growth"
style). Growth and Income will ordinarily invest substantially all of its assets
in equity securities.

   The Series may engage in transactions in futures contracts solely for the
purpose of maintaining full exposure of the portfolio to the movements of broad
equity markets at times when the Series holds a cash position pending investment
in stocks or in anticipation of redemptions.

  Although Growth and Income's objective is long-term total return, it may sell
securities to reflect changes in Westpeak's assessment of the relative
attractiveness of particular investments.  As a result, Growth and Income, under
certain market conditions, may experience high portfolio turnover.  High
portfolio turnover involves correspondingly higher brokerage commissions than
would be experienced by a similar fund with lower turnover.

  The assets of Growth and Income that are not invested in equity securities
will be held in cash or invested as described below under "Miscellaneous
Investment Practices--Money Market Instruments."

Westpeak Stock Index Series

  As disclosed in the Prospectus, Stock Index uses the Standard & Poor's 500
Composite Stock Index ("S&P 500 Index") as the standard of performance
comparison. Westpeak believes that this index currently represents a significant
percentage of the total market value of all United States publicly traded common
stocks, is well known to investors, and is commonly regarded as representative
of the performance of United States publicly traded common stocks taken as a
whole.

  The S&P 500 Index is composed of 500 common stocks, most of which are listed
on the New York Stock Exchange. Standard & Poor's, which is not a sponsor of or
in any other way affiliated with the Series, chooses the 500 stocks included in
the S&P 500 Index on the basis of market value and industry diversification.
The S&P 500 Index assigns relative values to the stocks included in the index,
weighted according to each stock's total market value relative to the total
market value of the other stocks included in the index.  The stocks included in
the S&P 500 Index may change from time to time.

  Stock Index is not managed through traditional methods of investment
management, which typically attempt to use economic, financial and market
analysis to select undervalued stocks or stocks of companies that may experience
above-average growth, nor will the adverse financial situation of a company
necessarily result in the elimination of its stock from Stock Index's portfolio.
As described in the Prospectus, stocks will be selected in an attempt to mirror
the performance of the S&P 500 Index.  From time to time, adjustments may be
made in Stock Index's investment portfolio, but such changes should be
infrequent compared to those of most management investment companies.  Westpeak
currently expects that such adjustments will ordinarily be made on a monthly
basis, but such adjustments could be made more or less frequently, depending on
changes in the size of Stock Index, among other factors.  As a consequence of
the relative infrequency of portfolio adjustments, brokerage and other
transaction costs are expected to be relatively low.  However, these costs and
other expenses may cause the return of Stock Index to be lower than the return
of the S&P 500 Index.  In addition, the relative infrequency of portfolio
adjustments may result in increased tracking error, to the extent that new cash
that has come into the Series is held, or invested in money market instruments
and repurchase agreements, pending the next portfolio adjustment, rather than
invested immediately in common stocks included in the S&P 500.

   It is Stock Index's  policy to be fully invested in common stocks.  However,
Stock Index may hold a portion of its assets, which will not exceed 5% (not
including additional cash that has come into the Series and is pending
investment in common stocks), in cash to meet redemptions and other day-to-day
operating expenses.  The Series may also engage in 

                                      -7-
<PAGE>
 
futures transactions to reduce tracking error. ("Tracking error" is a
statistical measure of the difference between the investment results of the
Series, before taking into account the Series' expenses, and the investment
results of the S&P 500 Index.) In addition, the Stock Index may invest cash
temporarily in money market instruments and repurchase agreements, as described
below under "Miscellaneous Investment Practices -- Money Market Instruments".
Such temporary investments will only be made with cash held to maintain
liquidity or pending investment, and will not be made for defensive purposes in
the event or in anticipation of a general decline in the market prices of stocks
in which the Series invests. A defensive investment posture is precluded by the
Stock Index's investment objective to provide investment results that correspond
to the price and yield performance of a universe of common stocks. Investors in
Stock Index therefore bear the risk of general declines in stock prices in the
stock markets.

  The index that Stock Index uses as a standard of comparison in seeking to
achieve its objective may be changed without shareholder approval.  At some time
in the future, another index may be selected if such a standard of comparison is
deemed more appropriate than the S&P 500 Index as an indicator of the
performance of United States publicly traded common stocks.

Loomis Sayles Balanced Series

   The Series' investment objective is reasonable long-term investment return
from a combination of long-term capital appreciation and moderate current
income.

  The Series is "flexibly managed" in that sometimes it invests more heavily in
equity securities and at other times it invests more heavily in fixed-income
securities, depending on Loomis Sayles' view of the economic and investment
outlook. Most of the Series' equity investments are normally in dividend-paying
common stocks of recognized investment quality that are expected to achieve
growth in earnings and dividends over the long term.  Fixed-income securities
include notes, bonds, non-convertible preferred stock and money market
instruments.  The Series may invest in adjustable rate mortgage securities,
asset-backed securities and inverse floaters, subject to a limit of 5% of the
Series' assets for each of these instruments.  The Series may invest in
securities rated BB or Ba or lower by  S&P or Moody's (or in unrated securities
that Loomis Sayles determines to be of comparable quality).  During the fiscal
year ended December 31, 1998, 1.5% of the average month-end net assets of the
Series were invested in fixed-income securities rated in the rating category BB
or Ba (just below investment grade) and none of such assets were invested in
fixed-income securities rated below this level.  The Series invests at least 25%
of its assets in fixed-income securities and, under normal market conditions,
more than 50% of its assets in equity securities.  The Series also may invest in
foreign securities.

Back Bay Advisors Managed Series

  The investment objective of the Managed Series is to provide a favorable total
investment return through investment in a diversified portfolio. The Series
portfolio is expected to include a mix of (1) common stocks, (2) notes and bonds
and (3) money market instruments.  These investments will be made in proportions
that Back Bay Advisors deems appropriate for an investor who wishes to invest in
a portfolio containing a diversified mix of assets.

  The text of the SAI following the caption "Investment Objective and Policies -
- - Back Bay Advisors Money Market Series," contains a description of the money
market instruments in which the Managed Series may invest; for a fuller
description, see "Miscellaneous Investment Practices--Money Market Instruments,"
below.

  It is expected that more often than not the investment portfolio of the Series
will contain a higher proportion of common stocks than of notes and bonds, and a
higher proportion of notes and bonds than of money market instruments.  However,
Back Bay Advisors will make variations in the proportions of each investment
category in accordance with its assessment of the outlook for the economy and
the financial markets and its judgment about the relative attractiveness of each
asset type in light of economic conditions.  The Series may also engage in
futures transactions to manage its portfolio exposure to the risks of investment
in common stocks or notes and bonds.  The Series will engage in futures
transactions only to the extent allowed by state law and regulations.

  The investment practices with respect to the common stock portion of the
Series center upon selecting a portfolio of securities, drawn from the S&P 500
Index, which taken as a group can be characterized as high capitalization growth
issues.  A proprietary quantitative model is used to achieve an industry sector-
neutral investment approach.  In addition, as conditions warrant, a portion of
the stock portfolio may be invested in "value" situations, as identified by Back
Bay Advisors' quantitative model.  In the future, however, the Series may,
without shareholder approval, select a stock index other than the S&P 500 Index
as the standard of comparison for the Series' common stock investments, or
discontinue the practice of using a stock index as 

                                      -8-
<PAGE>
 
the standard of comparison for the common stock portion of the Series'
portfolio. The Series may invest a limited portion of its assets in securities
of foreign issuers and may invest in convertible securities.

  The portion of Managed Series' investment portfolio consisting of notes and
bonds will be invested in bonds of the types in which the Bond Income Series is
permitted to invest.  These investments may include bonds rated B or higher by
S&P or Moody's (or unrated bonds of similar quality). The risks associated with
lesser rated and unrated bonds, commonly known as "high yield debt" or "junk
bonds," are described under the heading "Miscellaneous Investment Practices."
The Series will purchase and sell securities for the bond portion of its
portfolio in anticipation of or in response to changes in yield relationships,
markets or economic conditions.  The bond portion of the Series' investment
portfolio will also be invested to take advantage of temporary disparities in
the relative values of certain sectors of the market for fixed-income
securities.  As a result of these policies, the bond portion of the Series'
portfolio, under certain market conditions, may experience high portfolio
turnover. During the fiscal year ended December 31, 1998, 2.6% of the average
month-end net assets of the Series were invested in fixed-income securities
rated in the rating category (BB or Ba) just below investment grade and no
assets were invested in fixed-income securities rated below this level.

  Because the securities in its portfolio are subject to price declines as well
as price advances, at times the net asset value per Managed Series share may be
less than a shareholder's original cost.  There can be no assurance that the
Managed Series' investment objective will be attained.


Salomon Brothers Strategic Bond Opportunities Series

   The investment objective of Strategic Bond is to seek a high level of total
return consistent with preservation of capital.

   Based upon the assessment by Salomon Brothers Asset Management Inc ("SBAM")
of the relative risks and opportunities available in various market segments,
assets will be allocated among U.S. Government obligations, mortgage backed
securities, domestic and foreign corporate debt and sovereign debt securities
rated investment grade (BBB or higher by S&P or Baa or higher by Moody's), or if
unrated, but deemed to be of comparable quality in the subadviser's judgment,
and domestic and foreign corporate debt and sovereign debt securities rated
below investment grade.  The Series may invest in fixed and floating rate loans
("Loans") arranged through private negotiations between a foreign sovereign
entity and one or more financial institutions, in the form of participation in
such Loans and assignments of all or a portion of such loans from third parties.
See "Miscellaneous Investment Practices--Loan Participations and Assignments"
below.
    
   Depending on market conditions, the Series may invest without limit in high
yield debt, which involve significantly greater risks, including price
volatility and risk of default in the payment of interest and principal, than
investments in higher-quality securities.  Although SBAM does not anticipate
investing in excess of 75% of the Series' assets in domestic and developing
country debt securities that are rated below investment grade, the Series may
invest a greater percentage in such securities when, in the opinion of the
subadviser, the yield available from such securities outweighs their additional
risks. Certain of the debt securities in which the Series may invest may be
rated as low as "C" by Moody's or "D" by S&P or, if unrated, determined to be of
comparable quality to securities so rated.  Securities rated below investment
grade quality are considered high yield, high risk securities and are commonly
known as "high yield debt" or  "junk bonds." See "Miscellaneous Investment
Practices--Lower Rated Fixed-Income Securities" below.  During the fiscal year
ended December 31, 1998, 14.3% of the average month-end net assets of the Series
were invested in fixed-income securities rated in the rating category (BB or Ba)
just below investment grade and 23.5% of the Series assets were invested in
fixed-income securities below this level.  See Appendix A for more complete
information on bond ratings.      

   In addition, the Series may invest in securities issued or guaranteed as to
principal or interest by the U.S. Government or its agencies or
instrumentalities, including mortgage backed securities, and may also invest in
preferred stocks, convertible securities (including those issued in the
Euromarket), securities carrying warrants to purchase equity securities,
privately placed debt securities, stripped mortgage securities, zero coupon
securities and inverse floaters.

   The Series may, and SBAM anticipates that under certain market conditions it
will, invest up to 100% of its assets in foreign securities, including Brady
Bonds.  Brady Bonds are debt obligations created through the exchange of
commercial bank loans for new obligations under a plan introduced by former U.S.
Treasury Secretary Nicholas Brady.  See "Miscellaneous Investment Practices--
High Yield/High Risk Foreign Sovereign Debt Securities" below.  There is no
limit on the value of the Series' assets that may be invested in the securities
of any one country or in assets denominated in any one country's currency.

                                      -9-
<PAGE>
 
   The Series may also invest in debt obligations issued or guaranteed by a
foreign sovereign government or one of its agencies or political subdivisions
and debt obligations issued or guaranteed by supranational entities.
Supranational entities include international organizations designated or
supported by governmental entities to promote economic reconstruction or
development and international banking institutions and related government
agencies.  Examples include the International Bank for Reconstruction and
Development (the "World Bank"), the European Coal and Steel Community, the Asian
Development Bank and the Inter-American Development Bank.  Such supranational
issued instruments may be denominated in multi-national currency units.

   The Series currently intends to invest substantially all of its assets in
fixed-income securities.  In order to maintain liquidity, the Series may invest
up to 20% of its assets in high-quality short-term money market instruments.

   The Series' subadviser has the discretion to select the range of maturities
of the various fixed-income securities in which the Series will invest.  The
weighted average life of the Series may vary substantially from time to time
depending on economic and market conditions.

   The Series may purchase and sell (or write) exchange-listed and over-the-
counter put and call options on securities, financial futures contracts, fixed-
income indices and other financial instruments, enter into financial futures
contracts, enter into interest rate transactions and enter into currency
transactions.  Interest rate transactions may take the form of swaps, structured
notes, caps, floors and collars, and currency transactions may take the form of
currency forward contracts, currency futures contracts, currency swaps and
options on currencies or currency futures contracts.  See "Futures and Other
Hedging Transactions" under "Investment Risks" below and "Futures" in the
Statement.

   The Series may lend securities it owns so long as such loans do not represent
more than 20% of the Series' total assets.
    
  Although the Series' investment objective is a high level of total return
consistent with the preservation of capital, it frequently sells securities to
reflect changes in market, industry or individual company conditions or outlook
even though it may only have held those securities for a short period. As a
result of these policies, the Series, under certain market conditions, may
experience high portfolio turnover, although specific portfolio turnover rates
are impossible to predict. In recent years, the portfolio turnover rate of the
Series has fluctuated considerably as a result of strategic shifts in portfolio
holdings designed to maintain an optimum portfolio structure in view of general
market conditions and movements in individual stock prices.       

Back Bay Advisors Bond Income Series

   The investment objective of the Series is to provide a high level of current
income consistent with protection of capital. In general, fixed-income
securities, such as the bonds in which the Series may invest, are subject to
credit risk (the risk that the obligor will default in the payment of principal
and/or interest) and to market risk (the risk that the market value of the
securities will change as a result of changes in market rates of interest).  The
Series may also invest in convertible securities and Rule 144A securities.

   At least 80% of the Series' assets will consist of securities rated AAA, AA,
A, BBB or BB by S&P or Aaa, Aa, A or Baa by Moody's, or unrated but determined
by Back Bay Advisors, the Series' subadviser, to be of comparable quality to
securities in those rating categories.  The Series may not invest more than 10%
of its total net assets in obligations of foreign issuers.  The Series will
invest in these securities only when Back Bay Advisors believes the associated
risks are minimal.
    
   Up to 20% of the Series' assets may be invested in securities rated BB or B
by S&P or Ba or B by Moody's at the time of investment.  The Series will not
invest in any securities rated below B at the time of investment (or if unrated
securities that Back Bay Advisors determines to be of comparable quality).
During the fiscal year ended December 31, 1998, 17% of the average month-end net
assets of the Series were invested in fixed-income securities rated in the
rating category (BB or Ba) just below investment grade and no assets were
invested in fixed-income securities rated below this level.  Securities rated B
or lower by S&P or Moody's (or unrated but determined to be of comparable
quality by Back Bay Advisors) are considered high yield, high risk securities
and are commonly known as "high yield debt" or "junk bonds." If a security held
by the Series is downgraded below B, Back Bay Advisors will determine at that
time whether the Series will continue to hold the security, taking into account
the current conditions.  See Appendix A for more complete information on bond
ratings.      
 
   The Series may lend securities it owns so long as such loans do not exceed
15% of the Series' total assets.

   The average maturity of Bond Income Series' portfolio will usually be between
five and fifteen years.

Salomon Brothers U.S. Government Series

   The U.S. Government Series' investment objective is to provide a high level
of current income consistent with preservation of capital and maintenance of
liquidity.
    
   SBAM seeks to achieve the Series' investment objective by investing primarily
in debt obligations (including mortgage backed securities) issued or guaranteed
by the U.S. Government or its agencies, authorities or instrumentalities or
derivative securities (such as collateralized mortgage obligations) backed by
such securities.      

   At least 80% of the total assets of the Series will be invested in:

      (1) mortgage backed securities guaranteed by the Government National
   Mortgage Association ("GNMA") which are supported by the full faith and
   credit of the U.S. Government.  Such securities entitle the holder to receive
   all interest and principal payments when due, whether or not payments are
   actually made on the underlying mortgages;

      (2) U.S. Treasury obligations;

      (3) debt obligations issued or guaranteed by agencies or instrumentalities
   of the U.S. Government which are backed by their own credit but are not
   necessarily backed by the full faith and credit of the U.S. Government;

      (4) mortgage-related securities guaranteed by agencies or
   instrumentalities of the U.S. Government which are supported by their own
   credit but not the full faith and credit of the U.S. Government, such as the
   Federal Home Loan Mortgage Corporation and Federal National Mortgage
   Association ("FNMA"), and

      (5) collateralized mortgage obligations issued by private issuers for
   which the underlying mortgage backed securities serving as collateral are
   backed (i) by the credit of the U.S. Government agency or instrumentality
   which issues or guarantees the mortgage backed securities, or (ii) by the
   full faith and credit of the U.S. Government.

   Under normal market conditions, at least 65% of the Series' total assets will
be invested in securities issued or guaranteed by the U.S. Government or an
agency, authority or instrumentality thereof.  For purposes of this policy,
securities that are not issued or guaranteed by the U.S. Government or an
agency, authority or instrumentality will not count toward the 65% minimum, even
if they are backed by mortgages (or other collateral) that are so guaranteed.

   Any guarantee of the securities in which the Series invests runs only to
principal and interest payments on the securities and not to the market value of
such securities or the principal and interest payments on the underlying
mortgages.  In addition, the guarantee runs to the portfolio securities held by
the Series and not to the purchase of shares of the Series.

   The Series may purchase or write options on securities, options on securities
indices and options on futures contracts and may buy or sell futures on
financial instruments and securities indices.

   Up to 20% of the total assets of the Series may be invested in marketable
debt securities of domestic issuers and of foreign issuers (payable in U.S.
dollars) rated at the time of purchase Baa or higher by Moody's or BBB or higher
by S&P, or, if unrated, deemed by SBAM to be of comparable quality, convertible
securities (including those issued in the Euromarket), securities carrying
warrants to purchase equity securities and privately placed debt securities.

   The Series may lend securities it owns so long as such loans do not represent
more than 20% of the Series' total assets.

  Although the Series' objective is a high level of total return consistent with
the preservation of capital, it frequently sells securities to reflect changes
in market, industry or individual company conditions or outlook even though it
may only have held those securities for a short period.  As a result of these
policies, the Series, under certain market conditions, may experience high
portfolio turnover, although specific portfolio turnover rates are impossible to
predict.  In recent years, the 

                                      -11-
<PAGE>
 
portfolio turnover rate of the Series has fluctuated considerably as a result of
strategic shifts in portfolio holdings designed to maintain an optimum portfolio
structure in view of general market conditions and movements in individual stock
prices

Back Bay Advisors Money Market Series

     Money Market seeks the highest possible level of current income consistent
with preservation of capital through investment in a managed portfolio of high
quality money market instruments including: (1) obligations backed by the full
faith and credit of the United States Government, such as bills, notes and bonds
issued by the U.S. Treasury or by such government agencies as the Farmers' Home
Administration or the Small Business Administration; (2) other obligations
issued or guaranteed by the United States Government or its agencies,
authorities or instrumentalities, such as obligations of the Tennessee Valley
Authority, Federal Land Banks and FNMA (together with full faith and credit
obligations, "U.S. Government Securities"); (3) commercial paper and other
corporate debt obligations rated in the highest rating category by S&P or
Moody's or, if unrated, of comparable quality as determined by Back Bay
Advisors, the Series' subadviser, under guidelines approved by the Fund's
Trustees; (4) repurchase agreements relating to any of the above and (5)
obligations of banks or savings and loan associations (such as bankers'
acceptances and certificates of deposit, including Eurodollar obligations of
foreign branches of U.S. banks and dollar denominated obligations of U.S. and
United Kingdom branches of foreign banks) whose net assets exceed $100,000,000;
 
   The Series may invest up to 100% of its assets in certificates of deposit,
bankers' acceptances and other bank obligations.

   By investing only in high quality, short-term securities, the Series seeks to
minimize credit risk and market risk.  Credit risk is the risk that the obligor
will default in the payment of principal and/or interest.  In a repurchase
agreement transaction, credit risk relates to the performance by the other party
of its obligation to repurchase the underlying security from the Series.  If the
other party defaults on that obligation, the Series may face various delays and
risks of loss.  Market risk is the risk that the market value of the securities
will change as a result of changes in market rates of interest.  The Series
expects that those changes will be relatively small and that the Series will be
able to maintain the net asset value of its shares at a constant level of $100,
although this cannot be assured.
    
   The U.S. dollar-denominated obligations of foreign branches of U.S. banks
and U.S. and United Kingdom branches of foreign banks in which the Series may
invest may be subject to certain risks which do not apply to investments in
obligations of domestic branches of U.S. banks. These risks may relate to
foreign economic, political and legal developments and to the fact that foreign
banks and foreign branches of U.S. banks may be subject to different regulatory
requirements.      

     For a fuller description of those money market instruments and some of the
risks relating thereto, see "Miscellaneous Investment Practices - Money Market
Instruments" below. Money Market will invest only in securities which the
Series' subadviser acting pursuant to guidelines established by the Fund's Board
of Trustees, has determined are of high quality and present minimal credit risk.

  All the Series' investments mature in less than 397 days and the average
maturity of the Series' portfolio securities based on their dollar value will
not exceed 90 days at the time of each investment.  Money market instruments
maturing in less than 397 days, tend to yield less than obligations of
comparable quality having longer maturities.  See "Determination of Net Asset
Values"  and "Fund Performance."  Where obligations of greater than one year are
used to secure the Series' repurchase agreements, the repurchase agreements
themselves will have very short maturities.  If the disposition of a portfolio
security results in a dollar-weighted average portfolio maturity in excess of 90
days, the Series will invest its available cash in such a manner as to reduce
its dollar-weighted average portfolio maturity to 90 days or less as soon as
reasonably practicable.

  In seeking to provide the highest possible level of current income consistent
with preservation of capital, the Series may not necessarily invest in money
market instruments paying the highest available yield at a particular time.  The
Series, consistent with its investment objective, attempts to maximize income by
engaging in portfolio trading and by buying and selling portfolio investments in
anticipation of or in response to changing economic and money market conditions
and trends. The Series may also invest to take advantage of what are believed to
be temporary disparities in the yields of different segments of the high grade
money market or among particular instruments within the same segment of the
market.  These policies, as well as the relatively short maturity of obligations
to be purchased by the Series, may result in frequent changes in the Series'
investment portfolio of money market  instruments.

                                      -12-
<PAGE>
 
  The value of the securities in the Series' investment portfolio can be
expected to vary inversely to changes in prevailing interest rates.  Thus, if
interest rates increase after a security is purchased, that security, if sold,
might be sold at less than cost.  Conversely, if interest rates decline after
purchase, the security, if sold, might be sold at a profit.  In either instance,
if the security were held to maturity, no gain or loss would normally be
realized as a result of these fluctuations.  Substantial redemptions of shares
of the Series could require the sale of portfolio investments at a time when a
sale might not be desirable.



                            INVESTMENT RESTRICTIONS

   The following is a description of restrictions on the investments to be made
by the sixteen Series.  Except as specifically listed below, and except for
restrictions marked with an asterisk, these restrictions may not be changed
without the approval of a majority of the outstanding voting securities of the
relevant Series. Percentage tests regarding any investment restriction apply
only at the time of a Series is making that investment.  State insurance laws
and regulations may impose additional limitations on a Series' investments,
including its ability to borrow, lend, and use options, futures, and other
derivative instruments.  In addition, these laws may require that a Series'
investments meet additional diversification or other requirements.

Investment Restrictions Applicable to Capital Growth, Stock Index, Managed, Bond
Income and Money Market

   Each of the Series listed above will not:

      (1) Purchase any securities (other than the U.S. Government securities)
   if, as a result, more than 5% of the Series' total assets (taken at current
   value) would be invested in securities of a single issuer; provided, however,
   that Stock Index and the Managed Series may each invest more than 5% (but not
   more than 25%) of its total assets (taken at current value) in the securities
   of a single issuer if securities of any such issuer represent more than 5%,
   capitalization weighted, of the stock index that the Series attempts to
   track;

      (2) Purchase any security (other than the U.S. Government/Securities) if,
   as a result, more than 25% of the Series' total assets (taken at current
   value) would be invested in any one industry.  For purposes of this
   restriction, telephone, gas and electric public utilities are each regarded
   as separate industries and finance companies whose financing activities are
   related primarily to the activities of their parent companies are classified
   in the industry of their parents.  In the case of Money Market and the
   Managed Series, this restriction does not apply to bank obligations;

      (3) Purchase securities on margin (but it may obtain such short-term
   credits as may be necessary for the clearance of purchases and sales of
   securities); or make short sales, except where, by virtue of ownership of
   other securities, it has the right to obtain, without payment of further
   consideration, securities equivalent in kind and amount to those sold; or
   deposit or pledge more than 10% of its total assets (taken at current value)
   as collateral for such sales.  (Any deposit or payment by Stock Index or the
   Managed Series of initial or maintenance margin in connection with futures
   contracts shall not be considered the purchase of a security on margin for
   the purposes of this restriction);

      (4) Acquire more than 10% of the total value of any class of the
   outstanding securities of any issuer (taking all preferred stock issues of an
   issuer as a single class and all debt issues of an issuer as a single class)
   or acquire more than 10% of the outstanding voting securities of any issuer;

      (5) Borrow money, except as a temporary measure for extraordinary or
   emergency purposes (but not for the purpose of investment) up to an amount
   not in excess of 10% of its total assets (taken at cost), or 5% of its total
   assets (taken at current value), whichever is lower; provided, however, that
   the Bond Income Series, Capital Growth and the Managed Series may make loans
   of their portfolio securities.  (See "Loans of Portfolio Securities" above);

      (6) Invest more than 5% of its total assets (taken at current value) in
   securities of businesses (including predecessors) less than three years old;

      (7) Purchase or retain securities of any issuer if, to the knowledge of
  the Fund, officers and trustees of the Fund or officers and directors of any
  investment adviser of the Fund who individually own beneficially more than
  1/2 of 1% of the securities of that issuer, together own beneficially more
  than 5% of the securities of that issuer;

                                      -13-
<PAGE>
 
      (8) Act as underwriter except to the extent that, in connection with the
   disposition of portfolio securities, it may be deemed to be an underwriter
   under the federal securities laws; or purchase any security restricted as to
   disposition under the federal securities laws; provided, however, that,
   subject to the Fund's limitation on illiquid investments stated below, each
   of the Bond Income Series, Capital Growth and the Managed Series may invest
   up to 10% of its total assets (taken at current value) in such restricted
   securities;

      (9) Make investments for the purpose of exercising control or management;

      (10) Participate on a joint or joint and several basis in any trading
   account in securities.  (The "bunching" of orders for the purchase or sale of
   portfolio securities with MetLife or its affiliates, Back Bay Advisors, CGM,
   Westpeak or accounts under their management to reduce acquisition costs, to
   average prices among such accounts to facilitate such transactions, is not
   considered participating in a trading account in securities);

      (11) Invest in the securities of other investment companies, except in
   connection with a merger, consolidation or similar transaction, and except
   that the Bond Income Series, Capital Growth, Stock Index and the Managed
   Series may invest in securities of other investment companies by purchases in
   the open market involving only customary broker's commissions.  (Under the
   Investment Company Act of 1940 (the "1940 Act") each Series generally may not
   (a) invest more than 10% of its total assets (taken at current value) in the
   securities of other investment companies, (b) own securities of any one
   investment company having a value in excess of 5% of that Series' total
   assets (taken at current value), or (c) own more than 3% of the outstanding
   voting stock of any one investment company);

      (12) Buy or sell oil, gas or other mineral leases, rights or royalty
   contracts, commodities or commodity contracts (except that Stock Index and
   the Managed Series may buy or sell futures contracts on stock indexes and the
   Managed Series may buy or sell interest rate futures contracts) or real
   estate.  This restriction does not prevent any Series from purchasing
   securities of companies investing in real estate or of companies which are
   not principally engaged in the business of buying or selling such leases,
   rights or contracts;

      (13) Pledge, mortgage or hypothecate more than 15% of its total assets
   (taken at cost).

   Restrictions (1) and (2) apply to securities subject to repurchase agreements
but not to the repurchase agreements themselves.

   Each of the Series listed above will not purchase any illiquid security if,
as a result, more than 15% (10% in the case of Money Market) of its net assets
(taken at current value) would be invested in such securities.

Investment Restrictions Applicable to Individual Series

Capital Growth; Stock Index Series
    
   Neither Capital Growth nor Stock Index will:      

          Make loans, except by purchase of bonds, debentures, commercial paper,

its assets.

Back Bay Advisors Managed Series

   The Managed Series will not:

      (1) Make loans, except by purchase of bonds, debentures, commercial paper,
   corporate notes and similar evidences of indebtedness which are a part of an

   "Miscellaneous Investment Practices--Lending of Portfolio Securities" below;

      (2) Purchase options or warrants if, as a result, more than 1% of its
   total assets (taken at current value) would be invested in such securities;
   provided, however, that the Managed Series may, without regard to the
   foregoing percentage limit, purchase warrants or other rights to subscribe to
   securities of companies issuing such warrants or rights, or of parents or
   subsidiaries of such companies, provided that such warrants or other rights
   to subscribe are attached to, or a part of a unit offering involving, other
   securities.

   In order to comply with certain state requirements applicable to restriction
(13) above, as a matter of operating policy subject to change without
shareholder approval, the Managed Series will not pledge more than 2% of its
assets.

Investment Restrictions Applicable to Small Cap, International Equity, Equity
Growth, Venture Value, Midcap Value, Growth and Income, Balanced, Strategic Bond
and U.S. Government Series

   Each of the Series listed above will not:

  *(1)    With respect to 75% of the Series' total assets, purchase any security
  (other than U.S. Government securities) if, as a result, more than 5% of the
  Series' total assets (taken at current value) would then be invested in
  securities of a single issuer;

  (2)     Purchase any security (other than U.S. Government securities) if, as a
  result, more than 25% of the Series' total assets (taken at current value)
  would be invested in any one industry (in the utilities category, gas,
  electric, water and telephone companies will be considered as being in
  separate industries, and each foreign country's government (together with
  subdivisions thereof) will be considered to be a separate industry);

                                      -15-

  *(3)       Purchase securities on margin (but it may obtain such short-term

  consideration, securities equivalent in kind and amount to those sold; or
  deposit or pledge more than 10% of its total assets (taken at current value)
  as collateral for such sales.  (For this purpose, the deposit or payment by
  the Series of initial or variation margin in connection with futures contracts
  or related options transactions is not considered the purchase of a security
  on margin);

  *(4)      With respect to 75% of the Series' total assets acquire more than
  10% of the outstanding voting securities of an issuer;

  (5)       Borrow money in excess of 10% of its total assets (taken at cost) or
  5% of its total assets (taken at current value), whichever is lower, and then
  only as a temporary measure for extraordinary or emergency purposes;

  *(6)      Pledge more than 15% of its total assets (taken at cost).  (For the
  purpose of this restriction, collateral arrangements with respect to options,

  reverse repurchase agreements) or by purchase of bonds, debentures, commercial

  Risks--Lending of Portfolio Securities" above;

  (8)       Buy or sell real estate or commodities or commodity contracts,
  except that the Series may buy and sell futures contracts and option. Each

  agreements and other financial transactions not requiring the delivery of
  physical commodities. (This restriction does not prevent the Series from
  purchasing securities of companies investing in the foregoing);

  (9)       Act as underwriter, except to the extent that, in connection with
  the disposition of portfolio securities, it may be deemed to be an underwriter
  under certain federal securities laws;

  *(10)     Except to the extent permitted by rule or order of the SEC,
  participate on a joint or joint and several basis in any trading account in
  securities. (The "bunching" of orders for the purchase or sale of portfolio
  securities for a Series with that Series' adviser or subadviser or accounts
  under their management to reduce brokerage commissions, to average prices
  among them or to facilitate such transactions is not considered a trading
  account in securities for purposes of this restriction);

  *(11)     Write, purchase or sell options except that the Series may (a)

  net assets (taken at current value) would be invested in such securities;

  (13)      Issue senior securities. (For the purpose of this restriction none
  of the following is deemed to be a senior security: any pledge or other
  encumbrance of assets permitted by restriction (6) above; any borrowing
  'permitted by restriction (5) above; any collateral arrangements with respect
  to options, futures contracts and options on futures contracts and with
  respect to initial and variation margin; the purchase or sale of options,
  forward contracts, futures contracts or options on futures contracts; and the
  issuance of shares of beneficial interest permitted from time to time by the
  provisions of the Fund's Agreement and Declaration of Trust and by the 1940
  Act, the rules thereunder, or any exemption therefrom.)

  For purposes of restriction (5), reverse repurchase agreements are not
  considered borrowings.


MFS Investors  and Research Managers Series

  Neither of the above Series shall:
 
  (1)       borrow amounts from banks in excess of 33 1/3% of its assets
including amounts borrowed;

                                      -16-
<PAGE>
 
   (2)      underwrite securities issued by other persons except insofar as the
Series may technically be deemed an underwriter under the Securities Act of
1933, as amended (the "1933 Act') in selling a portfolio security;
 
   (3)      purchase or sell real estate (including limited partnership interest
but excluding securities secured by real estate or interests therein and
securities of companies, such as real estate investment trust, which deal in
real estate or interests therein), interest in oil, gas, or mineral leases,
commodities or commodity contracts (excluding currencies and any type of option,
futures contracts and forward contracts) in the ordinary course of its business.
The Series reserve the freedom of action to hold and sell real estate, mineral
leases, commodities or commodities contracts (including currencies and any type
of option, futures contract and forward contracts) acquired as a result of the
ownership of securities;
 
   (4)      issue any senior securities except as permitted by the 1940 Act. For
purposes of this restriction, collateral arrangements with respect to any type
of swap, option, forward contracts and futures contracts and collateral
arrangements with respect to initial and variation margin are not deemed to be
the issuance of a senior security;
 
   (5)      make loans to other persons. For these purposes, the purchase of
commercial paper, the purchase of a portion or all of an issue of debt
securities, the lending of portfolio securities, or the investment of the
Series' assets in repurchase agreements shall not be considered the making of a
loan;  

   (6)      purchase any securities of an issuer of a particular industry, if as
a result, 25% or more of its gross assets would be invested in securities of
issuers whose principal business activities are in the same industry (except
there is no limitation with respect to obligations issued or guaranteed by the
U.S. Government or its agencies or instrumentalities and repurchase agreements
collateralized by such obligations); or

   *(7)     invest in illiquid investments, including securities subject to
legal or contractual restrictions on resale or for which there is no readily
available market (e.g. trading in the security is suspended, or, in the case of
unlisted securities, where no market exists) if more than 15% of the Series'
assets  (taken at market value) would be invested in such securities. Repurchase
agreements maturing in more than seven days will be deemed to be illiquid for
purposes of the Series' limitation on investment in illiquid securities.
Securities that are not registered under the 1933 Act, but are deemed to be
liquid by the Board of Trustees (or its delegee), will not be subject to this
15% limitation.

Variable Contract Related Investment Restrictions

   Separate accounts supporting variable life insurance and variable annuity
contracts are subject to certain diversification requirements imposed by
regulations adopted under the Code.  Because the Fund is intended as an
investment vehicle for variable life insurance and variable annuity separate
accounts, Section 817(h) of the Internal Revenue Code requires that the Fund's
investments, and accordingly the investments of each Series, be "adequately
diversified" in accordance with Regulations promulgated by the Department of the
Treasury.  Failure to do so means the variable life insurance and variable
annuity contracts would cease to qualify as life insurance and annuities for
federal tax purposes.  Regulations specifying the diversification requirements
have been issued by the Department of the Treasury.  The Fund intends to comply
with these requirements.

                       MISCELLANEOUS INVESTMENT PRACTICES

Money Market Instruments  - Obligations of foreign branches of U.S. banks and
- -------------------------                                                    
other foreign securities are subject to risks of foreign political, economic and
legal developments, which include foreign governmental restrictions adversely
affecting payment of principal and interest on the obligations, foreign
withholding and other taxes on interest income, and difficulties in obtaining
and enforcing a judgment against a foreign branch of a domestic bank.  With
respect to bank obligations, different risks may result from the fact that
foreign banks are not necessarily subject to the same or similar regulatory
requirements that apply to domestic banks.  For instance, such branches may not
be subject to the types of requirements imposed on domestic banks with respect
to mandatory reserves, loan limitations, examinations, accounting, auditing,
recordkeeping and the public availability of information.  Obligations of such
branches will be purchased by the Series only when the Series' adviser or
subadviser believes the risks are minimal.

  The following constitutes a description of the money market instruments which
may be purchased by the Back Bay Advisors Money Market Series, and by any of the
Series, some of which may only invest for temporary defensive purposes.

  U.S. Government Securities -- are bills, certificates of indebtedness, notes
and bonds issued by agencies, authorities and instrumentalities of the U.S.
Government.  Some obligations, such as those issued by the U.S. Treasury, the
Government National Mortgage Association, the Farmers' Home Administration and
the Small Business Administration, are backed by the full faith and credit of
the U.S. Treasury.  Other obligations are backed by the right of the issuer to
borrow from the U.S. Treasury or by the credit of the agency, authority or
instrumentality itself.  Such obligations include, but are not limited to,
obligations issued by the Tennessee Valley Authority, the Bank for Cooperatives,
Federal Home Loan Banks, Federal Intermediate Credit Banks, Federal Land Banks
and the Federal National Mortgage Association.


  In addition, Midcap Value, together with other registered investment companies
managed by Goldman Sachs Asset Management or its affiliates, may transfer
uninvested cash balances into a single joint account, the daily aggregate
balance of which will be invested in one or more repurchase agreements.

  Certificates of Deposit -- are certificates issued against funds deposited in
a bank, are for a definite period of time, earn a specified rate of return and
are normally negotiable.

  Bankers' Acceptances -- are short-term credit instruments used to finance the
import, export, transfer or storage of goods. They are termed "accepted" when a
bank guarantees their payment at maturity.

  Eurodollar Obligations -- are obligations of foreign branches of U.S. banks.

  Commercial Paper -- refers to promissory notes issued by corporations in order
to finance their short-term credit needs. For a description of commercial paper
ratings see Appendix A-2.

Repurchase Agreements - Agreements by which a Series purchases a security
- ---------------------                                                    
(usually a U.S. Government Security) and obtains a simultaneous commitment from
the seller (a member bank of the Federal Reserve System or, to the extent
permitted by the 1940 Act, a recognized securities dealer) to repurchase the
security at an agreed upon price and date.  Each Series, through the custodian
or subcustodian, receives delivery of the underlying securities collateralizing
repurchase agreements.  It is the Fund's policy that the market value of the
collateral be at least equal to 100% of the repurchase price in the case of a
repurchase agreement of one day duration and 102% on all other repurchase
agreements.  Each Series' adviser or subadviser is responsible for determining
that the value of the collateral is at all times at least equal to the
repurchase price.

     The resale price is in excess of the purchase price and reflects an agreed
upon market rate unrelated to the coupon rate on the purchased security.  Such
transactions afford the Series the opportunity to earn a return on temporarily
available cash at minimal market risk.  While the underlying security may be a
bill, certificate of indebtedness, note or bond issued by an agency, authority
or instrumentality of the United States Government, the obligation of the seller
is not guaranteed by the U.S. Government and there is a risk that the seller may
fail to repurchase the underlying security, or the seller may enter insolvency,
thereby delaying or limiting realization of collateral.  In such event, the
Series may be able to exercise rights with respect to the underlying security,
including possible disposition of the security in the market.  However, the
Series may be subject to various delays and risks of loss, including (a)
possible declines in the value of the underlying security during the period
while the Series seeks to enforce its rights thereto, (b) possible reduced
levels of income and lack of access to income during this period and (c)
inability to enforce rights and the expenses involved in attempted enforcement.

  U.S. Government Securities - The Series may invest in some or all of the
  --------------------------                                              
following U.S. Government Securities, as well as in other types of securities
issued or guaranteed by the U.S. Government or its agencies, authorities or
instrumentalities:

  U.S. Treasury Bills - Direct obligations of the United States Treasury which
are issued in maturities of one year or less. No interest is paid on Treasury
bills; instead, they are issued at a discount and repaid at full face value when
they mature. They are backed by the full faith and credit of the United States
Government.

  U.S. Treasury Notes and Bonds - Direct obligations of the United States
Treasury issued in maturities that vary between one and 40 years, with interest
normally payable every six months.  These obligations are backed by the full
faith and credit of the United States Government.

  "Ginnie Maes" - Debt securities issued by a mortgage banker or other mortgagee
which represent an interest in a pool of mortgages insured by the Federal
Housing Administration or the Farmer's Home Administration or guaranteed by the
Veterans Administration.  The Government National Mortgage Association ("GNMA")
guarantees the timely payment of principal and interest when such payments are
due, whether or not these amounts are collected by the issuer of these
certificates on the underlying mortgages.  Mortgages included in single family
or multi-family residential mortgage pools backing an issue of Ginnie Maes have
a maximum maturity of up to 30 years.  Scheduled payments of principal and
interest are made to the registered holders of Ginnie Maes (such as the Fund)
each month.  Unscheduled prepayments may be made by homeowners, or as a result
of a default.  Prepayments are passed through to the registered holder (such as
the Fund, which reinvests any prepayments) of Ginnie Maes along with regular
monthly payments of principal and interest.

  "Fannie Maes" - The Federal National Mortgage Association ("FNMA") is a
government-sponsored corporation owned entirely by private stockholders that
purchases residential mortgages from a list of approved seller/servicers.
Fannie Maes are pass-through securities issued by FNMA that are guaranteed as to
timely payment of principal and interest by FNMA but are not backed by the full
faith and credit of the United States Government.

  "Freddie Macs" - The Federal Home Loan Mortgage Corporation ("FHLMC") is a
corporate instrumentality of the United States Government.  Freddie Macs are
participation certificates issued by FHLMC that represent an interest in
residential mortgages from FHLMC's National Portfolio.  FHLMC guarantees the
timely payment of interest and ultimate collection of principal, but Freddie
Macs are not backed by the full faith and credit of the United States
Government.

  U.S. Government Securities often do not involve the same credit risks
associated with investments in other types of fixed-income securities, although,
as a result, the yields available from U.S. Government Securities are generally
lower than the yields available from corporate fixed-income securities.  Like
other fixed-income securities, however, the values of U.S. Government Securities
change as interest rates fluctuate.  Fluctuations in the value of portfolio
securities will not affect interest income on existing portfolio securities but
will be reflected in the Series' net asset value.  Since the magnitude of these
fluctuations will generally be greater at times when the Series' average
maturity is longer, under certain market conditions, a Series may, for temporary
defensive purposes, accept lower current income from short-term investments
rather than investing in higher yielding long-term securities.

     Equity Securities - The Series listed above may invest in equity
     -----------------                                               
securities.  Equity securities are more volatile and more risky than some other
forms of investment.  Therefore, the value of your investment in a Series may
sometimes decrease instead of increase.  Investments in companies with
relatively small capitalization may involve greater risk than is usually
associated with more established companies.  These companies often have sales
and earnings growth rates which exceed those of companies with larger
capitalization.  Such growth rates may in turn be reflected in more rapid share
price appreciation.  However, companies with smaller capitalization often have
limited product lines, markets or financial resources and they may be dependent
upon a relatively small management group.  The securities may have limited
marketability and may be subject to more abrupt or erratic movements in price
than securities of companies with larger capitalization or the market averages
in general.  The net asset value of a Series that invests in companies with
smaller capitalization, therefore, may fluctuate more widely than market
averages.

     Fixed-income Securities - The Series listed above may invest in fixed-
     -----------------------                                              
income securities. Fixed-income securities include a broad array of short,
medium and long term obligations issued by the U.S. or foreign governments,
government or international agencies and instrumentalities, and corporate
issuers of various types.  Some fixed-income securities represent
uncollateralized obligations of their issuers; in other cases, the securities
may be backed by specific assets (such as mortgages or other receivables) that
have been set aside as collateral for the issuer's obligation.  Fixed-income
securities generally involve an obligation of the issuer to pay interest or
dividends on either a current basis or at the maturity of the security, as well
as the obligation to repay the principal amount of the security at maturity.

                                      -21-
<PAGE>
 
Fixed-income securities involve both credit risk and market risk.  Credit risk
is the risk that the security's issuer will fail to fulfill its obligation to
pay interest, dividends or principal on the security.  Market risk is the risk
that the value of the security will fall because of changes in market rates of
interest.  Except to the extent values are affected by other factors such as
developments relating to a specific issuer, generally the value of a fixed-
income security can be expected to rise when interest rates decline and
conversely, the value of such a security can be expected to fall when interest
rates rise.  Some fixed-income securities also involve prepayment or call risk.
This is the risk that the issuer will repay a Series the principal on the
security before it is due, thus depriving the Series of a favorable stream of
future interest or dividend payments.  In addition, many fixed-income securities
contain call or buy-back features that permit their issuers to call or
repurchase the securities from their holders.  Such securities may present risks
based on payment expectations.  Although a Series would typically receive a
premium if an issuer were to redeem a security, if an issuer were to exercise a
"call option" and redeem the security during times of declining interest rates,
a Series may realize a capital loss on its investment if the security was
purchased at a premium and a Series may be forced to replace the called security
with a lower yielding security.

The short-term and medium-term fixed-income securities in which International
Equity may invest consists of (a) obligations of governments, agencies or
instrumentalities of any member state of the Organization for Economic
Cooperation and Development ("OECD"), including the United States; (b) bank
deposits and bank obligations (including certificates of deposit, time deposits
and bankers' acceptances) of banks organized under the laws of any member states
of the OECD, including the United States, denominated in any currency; (c)
finance company and corporate commercial paper and other short-term corporate
debt obligations of corporations organized under the laws of any member states
of the OECD, including the United States, meeting the Series' credit quality
standards, provided that no more than 20% of the Series' assets is invested in
any one of such issuers.  The short-term and medium-term securities in which the
Series may invest will be rated investment grade, or if unrated, determined to
be of comparable quality by MSAM.

Because interest rates vary, it is impossible to predict the income for any
particular period of a Series that invests in fixed-income securities.
Fluctuations in the value of a Series' investments in fixed-income securities
will cause a Series' net asset value to increase or decrease.
    
Duration is a measure of the price volatility of a bond equal to the weighted
average term to maturity of the bond's cash flows.  The weights are the present
values of each cash flow as a percentage of the present value of all cash flows.
The greater the duration of a bond, the greater its percentage price volatility.
Only a pure discount bond -- that is, one with no coupon or sinking-fund
payments -- has a duration equal to the remaining maturity of the bond, because
only in this case does the present value of the final redemption payment
represent the entirety of the present value of the bond.  For all other bonds,
duration is less then maturity.      

     The difference between duration and maturity depends on: (a) the size of
the coupon, (b) whether or not there are to be sinking-fund payments, and (c)
the yield to maturity represented by the bond's current market value.  The
higher the coupon the shorter the duration.  This is because the final
redemption payment accounts for a smaller percentage of the bond's current
value.  The higher the yield the shorter the duration.  This is because the
present values of the distant payments become less important relative to the
present values of the nearer payments.  A typical sinking fund reduces duration
by about 1.5 years.  For bonds of less than five years to maturity, duration
expands rapidly as maturity  expands. From 5 to 15 years remaining maturity,
duration continues to expand as maturity lengthens, but as a considerably slower
rate. Beyond 15 years' maturity, increments to duration are quite small, and
only  a bond with very low (or no) coupon would have a duration of more than 15
years.

There is a close relationship between duration and the price sensitivity of a
bond to changes in interest rates.  The relationship is approximately as
follows:

     Percent change in bond price = -(Duration x Absolute change in yield).

For example, a bond with 10 years' duration will decline (or rise) in price by
approximately 5 percent when yield increases (or decreases) by one half percent.
Similarly, a yield increase of 2 percent will produce a price decline of about
24 percent for a bond with 12 years' duration; but the same 2 percent yield
increase will produce a price decline if only some 10 percent for a bond with
five-years' duration.  This same relationship holds true for the duration and
price of the entire portfolio of a Series.
    
     Lower Rated Fixed-income Securities (High Yield Debt) Each Series listed
     -----------------------------------------------------                   
above may invest in high yield debt.  The Balanced Series, the Managed Series
and Strategic Bond may invest 100% of their total assets in high yield debt. 
     
                                      -22-
<PAGE>
 
Bond Income may invest 20% of its total assets, and each of Midcap Value and the
Research Managers Series may invest 10% of their total assets, in high yield
debt. Fixed-income securities rated BB or lower by S&P or Ba or lower by Moody's
(and comparable unrated securities) are of below "investment grade" quality, are
considered high yield, high risk securities and are commonly known as "high
yield debt" or "junk bonds". Lower quality fixed-income securities generally
provide higher yields, but are subject to greater credit and market risk than
higher quality fixed-income securities. Lower quality fixed-income securities
are considered predominantly speculative with respect to the ability of the
issuer to meet principal and interest payments. The ability of a Series
investing in lower quality fixed-income securities to achieve its investment
objective may be more dependent on the relevant adviser's or subadviser's own
credit analysis than it would be for a Series investing in higher quality bonds.
The market for lower quality fixed-income securities may be more severely
affected than some other financial markets by economic recession or substantial
interest rate increases, by changing public perceptions of this market or by
legislation that limits the ability of certain categories of financial
institutions to invest in these securities. In addition, the secondary market
may be less liquid for lower rated fixed-income securities. This lack of
liquidity at certain times may affect the valuation of these securities and may
make the valuation and sale of these securities more difficult. For more
information, including a detailed description of the ratings assigned by S&P and
Moody's, please refer to "Appendix A-1--Description of Bond Ratings."
    
Domestic Equity Depositary Receipts - Each of the Series listed above may invest
- -----------------------------------                                             
in Domestic Equity Depositary Receipts, subject to the restrictions on the
percentage of such Series' assets that may be represented by Investment Company
Securities. Domestic Equity Depositary Receipts are interests in a unit
investment trust ("UIT") that holds a portfolio of common stocks that is
intended to track the price and dividend performance of a particular index.
Common examples of Domestic Equity Depositary Receipts include S&P Depositary
Receipts ("SPDRs") and Nasdaq 100 Shares, which  may be obtained from the UIT
issuing the securities or purchased in the secondary market (SPDRs and Nasdaq
100 Shares are listed on the American Stock Exchange).      
    
Domestic Equity Depositary Receipts are issued in aggregations known as
"Creation Units" in exchange for a "Portfolio Deposit" consisting of (a) a
portfolio of securities substantially similar to the component securities
("Index Securities") of the relevant index (the "Target Index"), (b) a cash
payment equal to a pro rata portion of the dividends accrued on the UIT's
portfolio securities since the last dividend payment by the UIT, net of expenses
and liabilities, and (c) a cash payment or credit ("Balancing Amount") designed
to equalize the net asset value of the Target Index and the net asset value of a
Portfolio Deposit.      
    
Domestic Equity Depositary Receipts are not individually redeemable, except upon
termination of the UIT that issued them. To redeem, a Series must accumulate
enough Domestic Equity Depositary Receipts to reconstitute a Creation Unit.  The
liquidity of small holdings of Domestic Equity Depositary Receipts, therefore,
will depend upon the existence of a secondary market.  Upon redemption of a
Creation Unit, a Series will receive Index Securities and cash identical to the
Portfolio Deposit required of an investor wishing to purchase a Creation Unit
that day.      
    
The redemption price (and therefore the sale price) of Domestic Equity
Depositary Receipts is derived from and based upon the securities held by the
UIT that issued them.  Accordingly, the level of risk involved in the purchase
or redemption or sale of a Domestic Equity Depositary Receipt is similar to the
risk involved in the purchase or sale of traditional common stock, with the
exception that the price of Domestic Equity Depositary Receipts is based on the
value of a basket of stocks. Disruptions in the markets for the securities
underlying Domestic Equity Depositary Receipts purchased or sold by a Series
could result in losses on Domestic Equity Depositary Receipts.      
    
     Foreign Securities - Each of the Series listed above may invest in
     ------------------                                                
securities of issuers organized or headquartered outside the United States or
primarily traded outside the United States ("foreign securities").      

     Although investing in foreign securities may increase a Series'
diversification and reduce portfolio volatility, foreign securities may present
risks not associated with investments in comparable securities of U.S. issuers.
There may be less information publicly available about a foreign corporate or
governmental issuer than about a U.S. issuer, and foreign corporate issuers are
not generally subject to accounting, auditing and financial reporting standards
and practices comparable to those in the United States.  The securities of some
foreign issuers are less liquid and at times more volatile than securities of
comparable U.S. issuers.  Foreign brokerage commissions and securities custody
costs are often higher than in the United States.  With respect to certain
foreign countries, there is a possibility of governmental expropriation of
assets, confiscatory 

                                      -23-
<PAGE>
 
taxation, political or financial instability and diplomatic developments that
could affect the value of investments in those countries. A Series' receipt of
interest on foreign government securities may depend on the availability of tax
or other revenues to satisfy the issuer's obligations.

     A Series' investments in foreign securities may include investments in
countries whose economies or securities markets are not yet highly developed.
Special considerations associated with these investments (in addition to the
considerations regarding foreign investments generally) may include, among
others, greater political uncertainties, an economy's dependence on revenues
from particular commodities or on international aid or development assistance,
currency transfer restrictions, highly limited numbers of potential buyers for
such securities and delays and disruptions in securities settlement procedures.

     Since most foreign securities are denominated in foreign currencies or
trade primarily in securities markets in which settlements are made in foreign
currencies, the value of these investments and the net investment income
available for distribution to shareholders of a Series investing in these
securities may be affected favorably or unfavorably by changes in currency
exchange rates or exchange control regulations.  Changes in the value relative
to the U.S. dollar of a foreign currency in which a Series' holdings are
denominated will result in a change in the U.S. dollar value of the Series'
assets and the Series' income available for distribution.

     In addition, although part of a Series' income may be received or realized
in foreign currencies, the Series will be required to compute and distribute its
income in U.S. dollars.  Therefore, if the value of a currency relative to the
U.S. dollar declines after a Series' income has been earned in that currency,
translated into U.S. dollars and declared as a dividend, but before payment of
the dividend, the Series could be required to liquidate portfolio securities to
pay the dividend.  Similarly, if the value of a currency relative to the U.S.
dollar declines between the time a Series accrues expenses in U.S. dollars and
the time such expenses are paid, the amount of such currency required to be
converted into U.S. dollars will be greater than the equivalent amount in such
currency of such expenses at the time they were incurred.

     Each Series listed above may also purchase shares of investment companies
investing primarily in foreign securities, including shares of funds that invest
primarily in securities of issuers located in one foreign country or region.
Each Series may, subject to the limitations stated above, invest in World Equity
Benchmark Shares ("WEBS") and similar securities that invest in securities
included in foreign securities indices.
    
Foreign Equity Depositary Receipts -In addition to purchasing foreign securities
- ----------------------------------                                              
directly, each Series listed above may invest in foreign equity securities by
purchasing Foreign Equity Depositary Receipts. Foreign Equity Depositary
Receipts are instruments issued by a bank that represent an interest in equity
securities held by arrangement with the bank, and include American Depositary
Receipts ("ADRs"), European Depositary Receipts ("EDRs") and Global Depositary
Receipts ("GDRs"). ADRs represent the right to receive securities of foreign
issuers deposited in a domestic bank or a correspondent bank. ADRs are traded on
domestic exchanges or in the U.S. over-the-counter market and, generally, are in
registered form. EDRs and GDRs are receipts evidencing an arrangement with a
non-U.S. bank similar to that for ADRs and are designed for use in the non-U.S.
securities markets. EDRs and GDRs are not necessarily quoted in the same
currency as the underlying security.     
    
Foreign Equity Depositary Receipts can be either "sponsored" or "unsponsored."
Sponsored Foreign Equity Depositary Receipts are issued by banks in cooperation
with the issuer of the underlying equity securities.  Unsponsored Foreign Equity
Depositary Receipts are arranged without involvement by the issuer of the
underlying equity securities.  Less information about the issuer of the
underlying equity securities may be available in the case of unsponsored Foreign
Equity Depositary Receipts.      
    
To the extent a Series acquires Foreign Equity Depositary Receipts through banks
that do not have a contractual relationship with the foreign issuer of the
security underlying the Foreign Equity Depositary Receipts to issue and service
such Foreign Equity Depositary Receipts (unsponsored), there may be an increased
possibility that such Series would not become aware of and be able to respond to
corporate actions such as stock splits or rights offerings involving the foreign
issuer in a timely manner.  In addition, the lack of information may result in
inefficiencies in the valuation of such instruments.   Investment in Foreign
Equity Depositary Receipts does not eliminate the risks inherent in investing in
securities of non-U.S. issuers.  The market value of Foreign Equity Depositary
Receipts is dependent upon the market value of the underlying securities and
fluctuations in the relative value of the currencies in which the Foreign Equity
Depositary receipts and the underlying securities are quoted. However, by
investing in Foreign Equity Depositary Receipts, such as      

                                      -24-
<PAGE>
 
ADRs, that are quoted in U.S. dollars, a Series may avoid currency risks during
the settlement period for purchases and sales.
    
     Illiquid Securities  Each Series may invest up to 15% of its assets (10% in
     -------------------                                                        
the case of Money Market) in "illiquid securities," that is, securities which in
the opinion of the subadviser are not resalable at the price at which the Series
is valuing the security, within seven days, except as qualified below, including
securities whose disposition is restricted by federal securities laws. The
Series may purchase Rule 144A securities. These are privately offered securities
that can be resold only to certain qualified institutional buyers. Rule 144A
securities are treated as illiquid, unless the Series' adviser or subadviser has
determined, under guidelines established by the Fund's trustees, that the
particular issue of Rule 144A securities is liquid.      

     Convertible Securities - The Series listed above may invest in convertible
     ----------------------                                                    
securities, including corporate bonds, notes or preferred stocks of U.S. or
foreign issuers that can be converted into (that is, exchanged for) common
stocks or other equity securities.  Convertible securities also include other
securities, such as warrants, that provide an opportunity for equity
participation.  Because convertible securities can be converted into equity
securities, their values will normally vary in some proportion with those of the
underlying equity securities.  Convertible securities usually provide a higher
yield than the underlying equity, however, so that the price decline of a
convertible security may sometimes be less substantial than that of the
underlying equity security. The value of convertible securities that pay
dividends or interest, like the value of other fixed-income securities,
generally fluctuates inversely with changes in interest rates.  Warrants have no
voting rights, pay no dividends and have no rights with respect to the assets of
the corporation issuing them.  They do not represent ownership of the securities
for which they are exercisable, but only the right to buy such securities at a
particular price.

  Reverse Repurchase Agreements and Dollar Rolls - The Series may enter into
  -----------------------------------------------                           
reverse repurchase agreements and dollar rolls with qualified institutions to
seek to enhance returns.

  Reverse repurchase agreements involve sales by a  Series of portfolio assets
concurrently with an agreement by that Series to repurchase the same assets at a
later date at a fixed price.  During the reverse repurchase agreement period,
the Series continues to receive principal and interest payments on these
securities.

  The Series may enter into dollar rolls in which a Series sells securities for
delivery in the current month and simultaneously contracts to repurchase
substantially similar (same type and coupon) securities on a specified future
date. During the roll period, the Series forgoes principal and interest paid on
the securities.  The Series is compensated by the difference between the current
sales price and the forward price for the future purchase (often referred to as
the "drop") as well as by the interest earned on the cash proceeds of the
initial sale.
    
  The Series will establish a segregated account with its custodian in which it
will maintain liquid assets equal in value to its obligations in respect of
reverse repurchase agreements and dollar rolls. Reverse repurchase agreements
and dollar rolls involve the risk that the market value of the securities
retained by the Series may decline below the price of the securities the Series
has sold but is obligated to repurchase under the agreement. In the event the
buyer of securities under a reverse repurchase agreement files for bankruptcy or
becomes insolvent, the Series' use of the proceeds of the agreement may be
restricted pending a determination by the other party, or its trustee or
receiver, whether to enforce the Series' obligation to repurchase the
securities. Although reverse repurchase agreements and dollar rolls have certain
characteristics similar to borrowings, these investment techniques are not
considered borrowings by the Series for purposes of determining the limitations
on each Series' borrowings described under the heading "Investment
Restrictions".     

  Lending of Portfolio Securities - The Series listed above may lend its
  -------------------------------                                       
portfolio securities to broker-dealers under contracts calling for cash
collateral equal to at least the market value of the securities loaned, marked
to market on a daily basis.  The Series will continue to benefit from interest
or dividends on the securities loaned and will also receive interest through
investment of the cash collateral in short-term liquid investments, which may
include shares of money market funds subject to any investment restriction
described herein.   Any voting rights, or rights to consent, relating to
securities loaned pass to the borrower.  However, if a material event affecting
the investment occurs, such loans will be called so that the securities may be
voted by the Series.  A Series pays various fees in connection with such loans,
including shipping fees and reasonable custodian and placement fees.

  Privately-issued Mortgage Securities - The Series listed above may invest in
  ------------------------------------                                        
privately-issued pass through securities that provide for the monthly principal
and interest payments made by individual borrowers to pass through to investors
on a corporate basis, and in privately issued collateralized mortgage
obligations ("CMOs"; see the general description below). Privately-issued
mortgage securities are issued by private originators of, or investors in,
mortgage loans, including mortgage bankers, commercial banks, investment banks,
savings and loan associations and special purpose subsidiaries of the foregoing.
Since privately-issued mortgage certificates are not guaranteed by an entity
having the credit status of GNMA or FHLMC, 

                                      -25-
<PAGE>
 
such securities generally are structured with one or more types of credit
enhancement. For a description of the types of credit enhancements that may
accompany privately-issued mortgage securities, see "Types of Credit Support"
below. A Series will not limit its investments to asset-backed securities with
credit enhancements.

  Asset-backed Securities  As with mortgage securities, asset-backed securities
  -----------------------                                                      
are often backed by a pool of assets representing the obligation of a number of
different parties and use similar credit enhancement techniques.  For a
description of the types of credit enhancement that may accompany privately-
issued mortgage securities, see "Types of Credit Support" below.  A Series will
not limit its investments to asset-backed securities with credit enhancements.
Although asset-backed securities are not generally traded on a national
securities exchange, many such securities are widely traded by brokers and
dealers, and in such cases will not be deemed by that Series' subadviser (or by
CGM, in the case of Capital Growth) to be illiquid securities for the purposes
of the investment policy that limits a Series' investments in illiquid
securities to 15% of net assets (10% in the case of Money Market).

  Types of Credit Support - Mortgage securities and asset-backed securities are
  -----------------------                                                      
often backed by a pool of assets representing the obligations of a number of
different parties.  To lessen the effect of failure by obligors on underlying
assets to make payments, such securities may contain elements of credit support.
Such credit support falls into two categories:  (i) liquidity protection and
(ii) protection against losses resulting from ultimate default by an obligor on
the underlying assets. Liquidity protection refers to the provision of advances,
generally by the entity administering the pool of assets, to ensure that the
pass-through of payments  due on the underlying pool occurs in a timely fashion.
Protection against losses resulting from ultimate default enhances the
likelihood of ultimate payment of the obligations on at least a portion of the
assets in the pool. Such protection may be provided through guarantees,
insurance policies or letters of credit obtained by the issuer or sponsor from
third parties, through various means of structuring the transaction or through a
combination of such approaches.  A Series will not pay any additional fees for
such credit support, although the existence of credit support may increase the
price of a security.

  The ratings of mortgage securities and asset-backed securities for which
third-party credit enhancement provides liquidity protection or protection
against losses from default are generally dependent upon the continued
creditworthiness of the provider of the credit enhancement.  The ratings of such
securities could be subject to reduction in the event of deterioration in the
creditworthiness of the credit enhancement provider even in cases where the
delinquency and loss experience on the underlying pool of assets is better than
expected.

  Examples of credit support arising out of the structure of the transaction
include "senior subordinated securities" (multiple class securities with one or
more classes subordinate to other classes as to the payment of principal and
interest, with the result that defaults on the underlying assets are borne first
by the holders of the subordinated class), creation of "reserve funds" (where
cash or investments, sometimes funded from a portion of the payments on the
underlying assets, are held in reserve against future losses) and "over-
collateralization" (where the scheduled payments on, or the principal amount of,
the underlying assets exceed those required to make payment of the securities
and pay any servicing or other fees).  The degree of credit support provided for
each issue is generally based on historical information with respect to the
level of credit risk associated with the underlying assets.  Delinquency or loss
in excess of that which is anticipated could adversely affect the return on an
investment in such security.
 
  Stripped Mortgage Securities - Stripped mortgage securities are derivative
  ----------------------------                                              
multiclass mortgage securities.  Stripped mortgage securities may be issued by
agencies or instrumentalities of the U.S. Government, or by private issuers,
including savings and loan associations, mortgage banks, commercial banks,
investment banks and special purpose subsidiaries of the foregoing.  Stripped
mortgage securities have greater volatility than other types of mortgage
securities in which the Series invest.  Stripped mortgage securities may not be
as liquid as other securities in which the Series may invest.

  Stripped mortgage securities are usually structured with two classes that
receive different proportions of the interest and principal distributions on a
pool of mortgage assets.  A common type of stripped mortgage security will have
one class receiving some of the interest and most of the principal from the
mortgage assets, while the other class will receive most of the interest and the
remainder of the principal.  In the most extreme case, one class will receive
all of the interest (the interest-only or "IO" class), while the other class
will receive all of the principal (the principal-only or "PO" class).  The yield
to maturity on an IO class is extremely sensitive not only to changes in
prevailing interest rates but also the rate of principal payments (including
prepayments) on the related underlying mortgage assets, and a rapid rate of
principal payments may have a material adverse effect on the Series' yield to
maturity.  If the underlying mortgage assets experience greater than anticipated
prepayments of principal, the Series may fail to fully recoup its initial
investment in these securities even if the securities are rated in a top rating
category.

                                      -26-
<PAGE>
 
  As interest rates rise and fall, the value of IOs tends to move in the same
direction as interest rates.  The value of other mortgage securities, like other
debt instruments, will tend to move in the opposite direction of interest rates.
Accordingly, investing in IOs, in conjunction with the other mortgage securities
described herein, may reduce fluctuations in a Series' net asset value.

  In addition to the stripped mortgage securities described above, the Series
listed above may invest in similar securities such as "Super POs," "Levered IOs"
and "IOettes," all of which are more volatile than conventional POs or IOs.
Risks associated with instruments such as Super POs are similar in nature to
those risks related to investments in POs.  Risks connected with Levered IOs and
IOettes are similar in nature to those associated with IOs.  The Series may also
invest in other similar instruments developed in the future that are deemed
consistent with the investment objectives, policies and restrictions of the
Series.

  Under the Internal Revenue Code of 1986, as amended (the "Code"), POs may
generate taxable income from the current accrual of original issue discount,
without a corresponding distribution of cash to the portfolio.

  Swaps, Caps, Floors, Collars, Etc. - The Series listed above may enter into
  ----------------------------------                                         
interest rate, currency and index swaps, the purchase or sale of related caps,
floors and collars and other derivatives.  A Series will enter into these
transactions primarily to seek to preserve a return or spread on a particular
investment or portion of its portfolio, to protect against currency
fluctuations, as a duration management technique or to protect against any
increase in the price of securities a portfolio anticipates purchasing at a
later date.  A Series will not sell interest rate caps or floors if it does not
own securities or other instruments providing the income the portfolio may be
obligated to pay.  Interest rate swaps involve the exchange by a Series with
another party of their respective commitments to pay or receive interest (for
example, an exchange of floating rate payments for fixed rate payments with
respect to a notional amount of principal).  The purchase of an interest rate
cap entitles the purchaser to receive payments on a notional principal amount
from the party selling the cap to the extent that a specified index exceeds a
predetermined interest rate or amount.  The purchase of an interest rate floor
entitles the purchaser to receive payments of interest on a notional principal
amount from the party selling the interest rate floor to the extent that a
specified index falls below a predetermined interest rate or amount.  A collar
is a combination of a cap and a floor that preserves a certain return within a
predetermined range of interest rates or values.  A currency swap is an
agreement to exchange cash flows on a notional amount based on changes in the
values of the reference currencies.
    
  A Series will usually enter into interest rate swaps on a net basis, that is,
two payment streams are netted out in a cash settlement on the payment date or
dates specified in the instrument, with the portfolio receiving or paying, as
the case may be, only the net amount of the two payments.  To the extent that a
Series maintains in a segregated account with its custodian liquid assets
sufficient to meet its obligations under swaps, caps, floors, collars and other
similar derivatives (see below) these investments will not constitute senior
securities under the 1940 Act , as amended, and, thus, will not be treated as
being subject to the Series' borrowing restrictions.  A Series will not enter
into any swap, cap, floor, collar or other derivative transaction unless the
counterparty is deemed creditworthy by that Series' adviser or subadviser.  If a
counterparty defaults, the Series may have contractual remedies pursuant to the
agreements related to the transaction.  Caps, floors and collars may not be as
liquid as swaps.      
    
  The liquidity of such agreements will be determined by a Series' adviser or
subadviser based on various factors, including (1) the frequency of trades and
quotations, (2) the number of dealers and prospective purchasers in the
marketplace, (3) dealer undertakings to make a market, (4) the nature of the
security (including any demand or tender features), and (5) the nature of the
marketplace for trades (including the ability to assign or offset a portfolio's
rights and obligations relating to the investment). Such determination will
govern whether a swap will be deemed to be within the 15% restriction on
investments in illiquid securities.      

  Each Series will maintain cash and appropriate liquid assets in a segregated
custodial account to cover its current obligations under swap agreements.  If a
Series enters into a swap agreement on a net basis, it will segregate assets
with a daily value at least equal to the excess, if any, of the Series' accrued
obligations under the swap agreement over the accrued amount the Series is
entitled to receive under the agreement.  If a Series enters into a swap
agreement on other than a net basis, it will segregate assets with a value equal
to the full amount of the Series' accrued obligations under the agreement.

  Eurodollar Futures and Options - The Series listed above may make investments
  ------------------------------                                               
in Eurodollar instruments, which are typically dollar-denominated futures
contracts or options on those contracts that are linked to the London Interbank
Offered Rate ("LIBOR"), although foreign currency denominated instruments are
available from time to time.  Eurodollar futures contracts enable purchasers to
obtain a fixed rate for the lending of funds and sellers to obtain a fixed rate
for borrowings.  A 

                                      -27-
<PAGE>
 
Series might use Eurodollar futures contracts and options thereon to hedge
against changes in LIBOR, to which many interest rate swaps and fixed income
instruments are linked.
    
  High Yield/High Risk Foreign Sovereign Debt Securities - The Series listed
  ------------------------------------------------------                    
above (up to 75% of the net assets of Investors Series) may invest in these
bonds, which  are typically issued by developing or emerging countries, whose
ability to pay principal and interest may be adversely affected by many factors,
including high rates of inflation, high interest rates, currency exchange rate
fluctuations or difficulties, political uncertainty or instability, the
country's cash flow position, the availability of sufficient foreign exchange on
the date a payment is due, the relative size of its debt service burden to the
economy as a whole, the policy of the International Monetary Fund (the "IMF"),
the World Bank and other international agencies, the obligor's balance of
payments, including export performance, its access to international credit and
investments, fluctuations in the international prices of commodities which it
imports or exports and the extent of its foreign reserves and access to foreign
exchange. Currency devaluations may also adversely affect the ability of a
sovereign obligor to obtain sufficient foreign exchange to service its external
debt.      

  If a foreign sovereign obligor cannot generate sufficient earnings from
foreign trade to service its external debt, it may need to depend on continuing
loans and aid from foreign governments, commercial banks and multilateral
organizations, and inflows of foreign investment.  The commitment on the part of
these entities to make such disbursements may be conditioned on the government's
implementation of economic reforms or other requirements.  Failure to meet such
conditions may result in the cancellation of such third parties' commitments to
lend funds, which may further impair the obligor's ability or willingness to
timely service its debts.
     
  A Series may invest in the sovereign debt of foreign countries which have
issued or have announced plans to issue Brady Bonds, and expect that a
substantial portion of their investments in sovereign debt securities will
consist of Brady Bonds. Brady Bonds are debt securities issued under the
framework of the Brady Plan, an initiative announced by then U.S. Treasury
Secretary Nicholas F. Brady in 1989 as a mechanism for debtor nations to
restructure their outstanding external commercial bank indebtedness.  In
restructuring its external debt under the Brady Plan framework, a debtor nation
negotiates with its existing bank lenders as well as multilateral institutions
such as the World Bank and the IMF. The Brady Plan framework, as it has
developed, contemplates the exchange of commercial bank debt for newly issued
bonds (Brady Bonds). Brady Bonds may also be issued in respect of new money
being advanced by existing lenders in connection with the debt restructuring.
The World Bank and/or the IMF support the restructuring by providing funds
pursuant to loan agreements or other arrangements which enable the debtor nation
to collateralize the new Brady Bonds or to repurchase outstanding bank debt at a
discount. Under these arrangements with the World Bank or the IMF, debtor
nations have been required to agree to the implementation of certain domestic
monetary and fiscal reforms. Such reforms have included the liberalization of
trade and foreign investment, the privatization of state-owned enterprises and
the setting of targets for public spending and borrowing. These policies and
programs seek to promote the debtor country's economic growth and development.
Investors should recognize that the Brady Plan only sets forth general guiding
principles for economic reform and debt reduction, emphasizing that solutions
must be negotiated on a case-by-case basis between debtor nations and their
creditors.     

  Agreements implemented under the Brady Plan to date are designed to achieve
debt and debt-service reduction through specific options negotiated by a debtor
nation with its creditors.  As a result, the financial packages offered by each
country differ.  The types of options have included the exchange of outstanding
commercial bank debt for bonds issued at 100% of face value of such debt, which
carry a below-market stated rate of interest (generally known as par bonds),
bonds issued at a discount from face value of such debt (generally known as
discount bonds), bonds bearing an interest rate which increases over time and
bonds issued in exchange for the advancement of new money by existing lenders.
Regardless of the stated face amount and stated interest rate of the various
types of Brady Bonds, a Series will purchase Brady Bonds in secondary markets,
as described below, in which the price and yield to the investor reflect market
conditions at the time of purchase.  Brady Bonds issued to date have traded at a
deep discount from their face value.  Certain Brady Bonds have been
collateralized as to principal due at maturity (typically 30 years from the date
of issuance) by U.S. Treasury zero coupon bonds with a maturity equal to the
final maturity of such Brady Bonds, although the collateral is not available to
investors until the final maturity of the Brady Bonds.  Collateral purchases are
financed by the IMF, the World Bank and the debtor nations' reserves.  In
addition, interest payments on certain types of Brady Bonds may be
collateralized by cash or high-grade securities in amounts that typically
represent between 12 and 18 months of interest accruals on these instruments
with the balance of the interest accruals being uncollateralized.  A Series may
purchase Brady Bonds with no or limited collateralization, and will be relying
for payment of interest and (except in the case of principal collateralized
Brady Bonds) principal primarily on the willingness and ability of the foreign
government to make payment in accordance with the terms of the Brady Bonds.
Brady Bonds issued to date are purchased and sold in secondary markets through
U.S. securities dealers and other financial institutions and are generally
maintained through European transnational securities depositories.

     A Series may purchase Brady Bonds with no or limited collateralization, and
will be relying for payment of interest and (except in the case of principal
collateralized Brady Bonds) principal primarily on the willingness and ability
of the foreign government to make payment in accordance with the terms of the
Brady Bonds.  In the event of a default with respect to collateralized Brady
Bonds as a result of which the payment obligations of the issuer are
accelerated, the U.S. Treasury zero coupon obligations held as collateral for
the payment of principal will not be distributed to investors, nor will such
obligations be sold and the proceeds distributed.  The collateral will be held
by the collateral agent to the scheduled maturity of the defaulted Brady Bonds,
which will continue to be outstanding, at which time the face amount of the
collateral will equal the principal payments which would have then been due on
the Brady Bonds in the normal course.  In light of the residual risk of the
Brady Bonds and, among other factors, the history of default with respect to
commercial bank loans by public and private entities of countries issuing Brady
Bonds, investments in Brady Bonds are to be viewed as speculative.
 
     Sovereign obligors in developing and emerging countries have in the past
experienced substantial difficulties in servicing their external debt
obligations, which has led to defaults on certain obligations and the
restructuring of certain indebtedness including among other things, reducing and
rescheduling interest and principal payments by negotiating new or amended
credit agreements or converting outstanding principal and unpaid interest to
Brady Bonds and obtaining new credit to finance interest payments.  There can be
no assurance that the Brady Bonds and other foreign sovereign debt securities in
which a Series may invest will not be subject to similar restructuring
arrangements or to requests for new credit which may adversely affect the
Series' holdings.

Futures and Options on Futures - The Series listed above may purchase and sell
- ------------------------------                                                
futures and options on futures.

      Futures Contracts.  A futures contract is an agreement between two parties
to buy and sell a commodity or financial instrument (e.g., an interest-bearing
security, a currency or, in the case of futures contracts on the S&P 500 Index,
the value of the basket of securities comprising the Index) for a specified
price on a specified future date.  In the case of futures on an index, the
seller and buyer agree to settle in cash, at a future date, based on the
difference in value of the contract between the date it is opened and the
settlement date.  The value of each contract is equal to the value of the index
from time to time multiplied by a specified dollar amount.  For example, long-
term municipal bond index futures trade in contracts equal to $1000 multiplied
by the Bond Buyer Municipal Bond Index.

  When a trader, such as a Series, enters into a futures contract, it is
required to deposit with (or for the benefit of) its broker, as "initial
margin," an amount of cash or short-term high-quality securities (such as U.S.
Treasury Bills) equal to approximately 2% to 20% of the delivery or settlement
price of the contract (depending on applicable exchange rules). Initial margin
is held to secure the performance of the holder of the futures contract.  As the
value of the contract changes, the value of futures contract positions increases
or declines.  At the end of each trading day, the amount of such increase or
decline is received or paid respectively by and to the holders of these
positions.  The amount received or paid is known as "variation margin" or
"maintenance margin."  A Series with a long position in a futures contract will
establish a segregated account with the Series' custodian containing liquid
assets equal to the purchase price of the contract (less any margin on deposit).
For short positions in futures contracts, a Series will establish a segregated
account with the custodian with liquid assets that, when added to the amounts
deposited as margin, equal the market value of the instruments or currency
underlying the futures contracts.

  Although futures contracts by their terms may require actual delivery and
acceptance of securities, in most cases the contracts are closed out before
settlement.  Closing out a futures sale is effected by purchasing a futures
contract for the same aggregate amount of the specific type of financial
instrument or commodity and with the same delivery date. Similarly, the closing
out of a futures purchase is effected by the purchaser selling an offsetting
futures contract.

  Gain or loss on a futures position is equal to the net variation margin
received or paid over the time the position is held, plus or minus the amount
received or paid when the position is closed, minus brokerage commissions.

  Stock Index may purchase and sell futures contracts on the S&P 500 Index
solely for the purpose of reducing the risk of tracking error arising from
holding cash from new investments in the Series or in anticipation of
shareholder redemptions. The Managed Series may purchase and sell futures
contracts on interest-bearing securities or indices thereof, or on indices of
stock prices (such as the S&P 500 Index), to increase or decrease its portfolio
exposure to common stocks or to increase or decrease its portfolio exposure to
notes and bonds.  Growth and Income may engage in transactions in futures
contracts solely for the purpose of maintaining full exposure of the portfolio
to the movements of broad equity markets at times when the Series holds a cash
position pending investment in stocks or in anticipation of redemptions.

                                      -29-

  Options on Futures.  An option on a futures contract obligates the writer, in
return for the premium received, to assume a position in a futures contract (a
short position if the option is a call and a long position if the option is a
put), at a specified exercise price at any time during the period of the option.
Upon exercise of the option, the delivery of the futures position by the writer
of the option to the holder of the option generally will be accompanied by
delivery of the accumulated balance in the writer's futures margin account,
which represents the amount by which the market price of the futures contract,
at exercise, exceeds, in the case of a call, or is less than, in the case of a
put, the exercise price of the option.  The premium paid by the purchaser of an
option will reflect, among other things, the relationship of the exercise price
to the market price and volatility of the underlying contract, the remaining
term of the option, supply and demand and interest rates.  Options on futures
contracts traded in the United States may only be traded on a United States
board of trade licensed by the Commodity Futures Trading Commission.

  The Fund, on behlaf of each of the Series, has notified the Commodities
Futures Trading Commission, pursuant to Rule 4.5 under the Commodity Exchange
Act, that it desires to claim exclusion from the definition of the term
"Commodity Pool Operator".  In connection with such exclusion, the Fund has
represented, on behlaf of each Series, that the Fund will operate the Series in
a manner such that the Series:

  (i)   Will use commodity futures or commodity options contracts solely for 
  bona fide hedging purposes within the meaning and intent of Rule 1.3(z)(1) 
  under the Commodity Exchange Act; provided, however, that, in addition, with
                              --------  -------                                
  respect to positions in commodity futures or commodity option contracts which
  do not come within the meaning and intent of Rule 1.3(z)(1), the Series may
  enter into commodity futures and commodity options contracts for which the
  aggregate initial margin and premiums required to establish such positions
  will not exceed 5 percent of the fair market value of the Series' assets,
  after taking into account unrealized profits and unrealized losses on any such
  contracts it has entered into; provided, further, that in the case of an
                                 --------  ------- 
  option that is in-the-money at the time of purchase, the in-the-money amount
  as defined in Rule 190.01(x) under the Commodity Exchange Act may be excluded
  in computing such 5%;
 
  (ii)  Will not be, and has not been, marketing participation to the public as
  or in a commodity pool or otherwise as or in a vehicle for trading in the
  commodity futures or commodity options markets;

  (iii) Will disclose in writing to each prospective participant the purpose of
  and the limitations on the scope of the commodity futures and commodity
  options trading in which the Series intends to engage; and

  (iv)  Will submit to such special calls as the under the Commodity Futures
  Trading Commission may make to require the Trust on behalf of the Series to
  demonstrate compliance with the provisions of Rule 4.5(c) under the Commodity
  Exchange Act.

  For a discussion of additional risks related to futures and options, see the
discussion below.

  Options on Securities - An option on a security entitles the holder to receive
  ---------------------                                                         
(in the case of a call option) or to sell (in the case of a put option) a
particular security at a specified exercise price.  An "American style" option
allows exercise of the option at any time during the term of the option.  
A "European style" option allows an option to be exercised only at the end of
its term. Options on securities may be traded on or off a national securities
exchange. For a discussion of additional risks related to futures and options,
see the discussion below.
    
  Risks Related to Futures and Options.  The purchase and sale of futures
contracts, options on futures, and options on securities or indexes and options
involves risks.  One risk arises because of the imperfect correlation between
movements in the price of futures contracts or options and movements in the
price of the underlying securities or index.  The Series' use of      

                                      -30-
<PAGE>
 
futures contracts or options will not be fully effective unless the Series can
compensate for such imperfect correlation. There is no assurance that the Series
will be able to effect such compensation.

  The correlation between the price movement of a futures contract or option and
the related security (or index) may be distorted due to differences in the
nature of the markets.  If the price of the futures contract or option moves
more than the price of the security or index, the Series would experience either
a loss or a gain on the future or option that is not completely offset by
movements in the price of the security or index.  In an attempt to compensate
for imperfect price movement correlations, a Series may purchase or sell futures
contracts or options in a greater amount than the related securities or index
position if the volatility of the related securities or index is historically
greater than the volatility of the futures contracts or options.  Conversely,
the Series may purchase or sell fewer contracts or options if the volatility of
the price of the securities or index is historically less than that of the
contracts or options.

  There are many reasons why changes in the values of futures contracts or
options may not correlate perfectly with changes in the value of the underlying
security or index.  For example, all participants in the futures market are
subject to margin deposit and maintenance requirements.  Rather than meeting
additional margin deposit requirements, investors may close futures contracts
through offsetting transactions, which could distort the normal relationship
between the index and futures markets.  Secondly, the deposit requirements in
the futures market are less onerous than margin requirements in the securities
market, and as a result the futures market may attract more speculators than
does the securities market.  In addition, trading hours for index futures or
options may not correspond perfectly to hours of trading on the exchange where
the underlying securities trade.  This may result in a disparity between the
price of futures or options and the value of the underlying security or index
due to the lack of continuous arbitrage between the futures or options price and
the value of the underlying security or index.  Hedging transactions using
securities indices also involve the risk that movements in the price of the
index may not correlate with price movements of the particular portfolio
securities being hedged (since a Series will typically not own all of the
securities included in a particular index.)

  Price movement correlation also may be distorted by the limited liquidity of
certain futures or options markets and the participation of speculators in such
markets.  If an insufficient number of contracts are traded, commercial users
may not deal in futures contracts or options because they do not want to assume
the risk that they may not be able to close out their positions within a
reasonable amount of time.  In such instance, futures  and options market prices
may be driven by different forces than those driving the market in the
underlying securities, and price spreads between these markets may widen.  The
participation of speculators in the market generally enhances its liquidity.
Nonetheless, speculative trading spreads between futures markets may create
temporary price distortions unrelated to the market in the underlying
securities.

  Positions in futures contracts and related options are established or closed
out only on an exchange or board of trade regulated by the Commodity Futures
Trading Commission.  There is no assurance that a liquid market on an exchange
or board of trade will exist for any particular contract or at any particular
time.  The liquidity of markets in futures contracts may be adversely affected
by "daily price fluctuation limits" established by commodity exchanges which
limit the amount of fluctuation in a futures price during a single trading day.
Once the daily limit has been reached in a contract, no trades may be entered
into at a price beyond the limit, which may prevent the liquidation of open
futures positions.  Prices have in the past exceeded the daily limit on a number
of consecutive trading days.  If there is not a liquid market at a particular
time, it may not be possible to close a futures position at such time, and, in
the event of adverse price movements, the Series would continue to be required
to make daily cash payments of variation margin.  However, if futures or options
are used to hedge portfolio securities, an increase in the price of the
securities, if any, may partially or completely offset losses on the futures
contract.

  An exchange-traded option may be closed out only on a national securities or
commodities exchange which generally provides a liquid secondary market for an
option of the same series.  If a liquid secondary market for an exchange-traded
option does not exist, it might not be possible to effect a closing transaction
with respect to a particular option, with the result that the Series would have
to exercise the option in order to realize any profit.  If the Series that has
written an option is unable to effect a closing purchase transaction in a
secondary market, it will not be able to sell the underlying security until the
option expires or it delivers the underlying security upon exercise.  Reasons
for the absence of a liquid secondary market on an exchange include the
following:  (i) there may be insufficient trading interest in certain options;
(ii) restrictions may be imposed by an exchange on opening transactions or
closing transactions or both; (iii) trading halts, suspensions or other
restrictions may be imposed with respect to particular classes or series of
options or underlying securities; (iv) unusual or unforeseen circumstances may
interrupt normal operations on an exchange; (v) the facilities of an exchange or
the Options Clearing Corporation or other clearing organization may not at all
times be adequate to handle current trading volume or (vi) one or more exchanges
could, for economic or other reasons, decide or be compelled at some future date
to discontinue the trading of options (or a particular class or series of
options), in which event the secondary market on that exchange (or in that 

                                      -31-
<PAGE>
 
class or series of options) would cease to exist, although outstanding options
on that exchange that had been issued by the Options Clearing Corporation as a
result of trades on that exchange would continue to be exercisable in accordance
with their terms.

  Because the specific procedures for trading foreign futures and options on
futures exchanges are still evolving, additional or different margin
requirements as well as settlement procedures may be applicable to foreign
futures and options at the time the Series purchases foreign futures or options.

  The successful use of transactions in futures and options depends in part on
the ability of the Series to forecast correctly the direction and extent of
interest rate or securities price movements within a given time frame.  To the
extent interest rates or securities prices move in a direction opposite to that
anticipated, a Series may realize a loss that is not fully or partially offset
by an increase in the value of portfolio securities.  In addition, whether or
not interest rates or securities prices move during the period that the Series
holds futures or options positions, the Series will pay the cost of taking those
positions (i.e., brokerage costs).  As a result, the Series' total return for
such period may be less than if it had not engaged in the futures or option
transaction.

  Future Developments.  The above discussion relates to the Series' proposed use
of futures contracts, options and options on futures contracts and swap
transactions currently available.  The relevant markets and related regulations
are constantly evolving.  In the event of future regulatory or market
developments, the Series may also use additional types of futures contracts or
options and other similar or related investment techniques.

  Writing Options  -  The Series listed above may write covered call or put
  ---------------                                                          
options.  A call option on a futures contract written by a Series is considered
by the Series to be covered if the Series owns the security subject to the
underlying futures contract or other securities whose values are expected to
move in tandem with the values of the securities subject to such futures
contract, based on historical price movement volatility relationships.  A call
option on a security written by a Series is considered to be covered if the
Series owns a security deliverable under the option.  A written call option is
also covered if the Series holds a call on the same futures contract or security
as the call written where the exercise price of the call held (a) is equal to or
less than the exercise price of the call written or (b) is greater than the
exercise price of the call written if the difference is maintained by the Series
in liquid assets in a segregated account with its custodian.

  A put option on a futures contract written by a Series, or a put option on a
security written by a Series, is covered if the Series maintains cash, or other
liquid assets with a value equal to the exercise price in a segregated account
with the Series' custodian, or else holds a put on the same futures contract (or
security, as the case may be) as the put written where the exercise price of the
put held is equal to or greater than the exercise price of the put written.

  If the writer of an option wishes to terminate its position, it may effect a
closing purchase transaction by buying an option identical to the option
previously written.  The effect of the purchase is that the writer's position
will be canceled.  Likewise, the holder of an option may liquidate its position
by selling an option identical to the option previously purchased.

  Closing a written call option will permit the Series to write another call
option on the portfolio securities used to cover the closed call option.
Closing a written put option will permit the Series to write another put option
secured by the segregated cash  or other liquid assets used to secure the closed
put option.  Also, effecting a closing transaction will permit the cash or
proceeds from the concurrent sale of any futures contract or securities subject
to the option to be used for other Series investments.  If a Series desires to
sell particular securities covering a written call option position, it will
close out its position or will designate from its portfolio comparable
securities to cover the option prior to or concurrent with the sale of the
covering securities.

  The Series will realize a profit from closing out an option if the price of
the offsetting position is less than the premium received from writing the
option or is more than the premium paid to purchase the option; the Series will
realize a loss from closing out an option transaction if the price of the
offsetting option position is more than the premium received from writing the
option or is less than the premium paid to purchase the option.  Because
increases in the market price of a call option will generally reflect increases
in the market price of the covering securities, any loss resulting from the
closing of a written call option position is expected to be offset in whole or
in part by appreciation of such covering securities.

  Since premiums on options having an exercise price close to the value of the
underlying securities or futures contracts usually have a time value component
(i.e. a value that diminishes as the time within which the option can be
exercised grows shorter) an option writer may profit from the lapse of time even
though the value of the futures contract (or security in some cases) underlying
the option (and of the security deliverable under the futures contract) has not
changed.  Consequently, profit 

                                      -32-
<PAGE>
 
from option writing may or may not be offset by a decline in the value of
securities covering the option. If the profit is not entirely offset, the Series
will have a net gain from the options transaction, and the Series' total return
will be enhanced. Likewise, the profit or loss from writing put options may or
may not be offset in whole or in part by changes in the market value of
securities acquired by the Series when the put options are closed.

  An over-the-counter option (an option not traded on a national securities
exchange) may be closed out only with the other party to the original option
transaction.  While a Series will seek to enter into over-the-counter options
only with dealers who agree to or are expected to be capable of entering into
closing transactions with the Series, there can be no assurance that the Series
will be able to liquidate an over-the-counter option at a favorable price at any
time prior to its expiration.  Accordingly, the Series might have to exercise an
over-the-counter option it holds in order to realize any profit thereon and
thereby would incur transactions costs on the purchase or sale of the underlying
assets.  If the Series cannot close out a covered call option written by it, it
will not be able to sell the underlying security until the option expires or is
exercised.  Furthermore, over-the-counter options are not subject to the
protections afforded purchasers of listed options by the Options Clearing
Corporation or other clearing organization.

  The staff of the Securities and Exchange Commission (the "SEC") has taken the
position that over-the-counter options on U.S. Government Securities and the
assets used as cover for written over-the-counter options on U.S. Government
Securities should generally be treated as illiquid securities.  However, if a
dealer recognized by the Federal Reserve Bank of New York as a "primary dealer"
in U.S. Government Securities is the other party to an option contract written
by a mutual fund such as a Series, and such Series has the absolute right to
repurchase the option from the dealer at a formula price established in a
contract with the dealer, the SEC staff has agreed that the Series only needs to
treat as illiquid that amount of the "cover" assets equal to the amount by which
(i) the formula price exceeds (ii) any amount by which the market value of the
securities subject to the options exceeds the exercise price of the option (the
amount by which the option is "in-the-money").

  Foreign Currency Transactions, including Forward Contracts - The Series listed
  ----------------------------------------------------------                    
above may engage in foreign currency transactions to protect against a change in
the foreign currency exchange rate between the date on which a Series contracts
to purchase or sell a security that settles in a foreign currency and the
settlement date for the purchase or sale, or to "lock in" the equivalent of a
dividend or interest payment in another currency, the Series might purchase or
sell a foreign currency on a spot (or cash) basis at the prevailing spot rate.
Each Series may also purchase options on foreign currencies.  If conditions
warrant, a Series may also enter into contracts with banks or broker-dealers to
purchase or sell foreign currencies at a future date ("forward contracts").  The
Series will maintain cash or other liquid assets in a segregated account with
the custodian in an amount at least equal to (i) the difference between the
current value of the Series' liquid holdings that settle in the relevant
currency and the Series' outstanding net obligations under currency forward
contracts in that currency, or (ii) the current amount, if any, that would be
required to be paid to enter into an offsetting forward currency contract which
would have the effect of closing out the original forward contract.  The Series'
use of currency hedging transactions may be limited by tax considerations.  The
Series may also purchase or sell foreign currency futures contracts traded on
futures exchanges.  Foreign currency futures contract transactions involve risks
similar to those of other futures transactions.  See "Futures and Options on
Futures" and "Risks  related to Futures and Options" above.  Each Series may use
foreign currency transactions for hedging purposes only.

  Real Estate Investment Trusts ("REITs") - The Series listed above may invest
  ----------------------------------------                                    
in REITs, which are pooled investment vehicles which invest primarily in
investment in income producing real estate or real estate related loans or
interest.  REITs are generally classified as equity REITs, mortgage REITs or a
combination of equity and mortgage REITs.  Equity REITs invest the majority of
their assets directly in real property and derive income primarily from the
collection of rents.  Equity REITs can also realize capital gains by selling
properties that have appreciated in value.  Mortgage REITs invest the majority
of their assets in real estate mortgages and derive income from the collection
of interest payments.  Like regulated investment companies such as the Series,
REITs are not taxed on income distributed to shareholders provided that they
comply with certain requirements under the Code. The Series will indirectly bear
its proportionate share of any expenses paid by REITs in which it invests in
addition to the expenses paid by the Series.

  Investing in REITs involves certain unique risks.  Equity REITs may be
affected by changes in the value of the underlying property owned by such REITs,
while mortgage REITs may be affected by the quality of any credit extended.
REITs are dependent upon management skills, are not diversified (except to the
extent the Code requires), and are subject to the risk of financing projects.
REITs are subject to heavy cash flow dependency, defaults by borrowers, self-
liquidation, and the possibility of failing to qualify for the exemption from
tax for distributed income under the Code and failing to maintain their
exemption from the 1940 Act.  REITs, and mortgage REITs in particular, are also
subject to interest rate risk.

  Emerging Markets - The Series listed above may invest in the securities of
  ----------------                                                          
issuers in emerging countries (up to the limit of each Series' ability to invest
in foreign securities, except that Midcap Value may invest up to 15% of its
total assets in securities of issuers in emerging countries).  Investing in
securities of issuers in emerging countries involves risks in addition to those
discussed in the Prospectus under "Foreign Securities." Emerging countries are
generally located in the Asia-Pacific region, Eastern Europe, Latin and South
America and Africa.  The Series' purchase and sale of portfolio securities in
certain emerging countries may be constrained by limitations as to daily changes
in the prices of listed securities, periodic trading or settlement volume and/or
limitations on aggregate holdings of foreign investors.  Such limitations may be
computed based on the aggregate trading volume by or holdings of the Series, the
subadviser, its affiliates and their respective clients and other service
providers.  The Series may not be able to sell securities in circumstances where
price, trading or settlement volume limitations have been reached.
    
  Foreign investment in the securities markets of certain emerging countries is
restricted or controlled to varying degrees which may limit investment in such
countries or increase the administrative costs of such investments.  For
example, certain Asian countries require governmental approval prior to
investments by foreign countries or limit investment by foreign countries to
only a specified percentage of an issuer's outstanding securities or a specific
class of securities which may have less advantageous terms (including price)
than securities of the issuer available for purchase by nationals.  In addition,
certain countries may restrict or prohibit investment opportunities in issuers
or industries deemed important to national interests. Such restrictions may
affect the market price, liquidity and rights of securities that may be
purchased by the Series.  The repatriation of both investment income and capital
from certain emerging countries is subject to restrictions such as the need for
governmental consents.  Due to restrictions on direct investment in equity
securities in certain Asian countries, such as Taiwan, it is anticipated that
the Series may invest in such countries only through other investment funds in
such countries. See "Investment Company Securities", below.      

     Collateralized Mortgage Obligations - The Series listed above may invest in
     -----------------------------------                                        
collateralized mortgage obligations (a "CMO"). A CMO is a debt security
collateralized by a portfolio of mortgages or mortgage securities held under a
trust indenture.  In some cases, the underlying mortgages or mortgage securities
are issued or guaranteed by the U.S. Government or an agency or instrumentality
thereof, but the obligations purchased by a Series will in many cases not be so
issued or guaranteed.  The issuer's obligation to make interest and principal
payments is secured by the underlying portfolio of mortgages or mortgage
securities.  CMOs are issued with a number of classes or series which have
different maturities and which may represent interests in some or all of the
interest or principal on the underlying collateral or a combination thereof. In
the event of sufficient early prepayments on such mortgages, the class or series
of CMO first to mature generally will be retired prior to its maturity.  The
early retirement of a particular class or series of CMO held by a Series would
have the same effect as the prepayment of mortgages underlying a mortgage pass-
through security.

     Adjustable Rate Mortgage Securities - The Series listed above may invest in
     -----------------------------------                                        
Adjustable Rate Mortgage Securities ("ARM"). An ARM, like a traditional mortgage
security, is an interest in a pool of mortgage loans that provides investors
with payments consisting of both principal and interest as mortgage loans in the
underlying mortgage pool are paid off by the borrowers.  Unlike fixed rate
mortgage securities, ARMs are collateralized by or represent interests in
mortgage loans with variable rates of interest.  These interest rates are reset
at periodic intervals, usually by reference to some interest rate index or
market interest rate.  Although the rate adjustment feature may act as a buffer
to reduce sharp changes in the value of adjustable rate securities, these
securities are still subject to changes in value based on changes in market
interest rates or changes in the issuer's creditworthiness.  Because the
interest rates are reset only periodically, changes in the interest rate on ARMs
may lag changes in prevailing market interest rates.  Also, some ARMs (or the
underlying mortgages) are subject to caps or floors that limit the maximum
change in interest rate during a specified period or over the life of the
security.  As a result, changes in the interest rate on an ARM may not fully
reflect changes in prevailing market interest rates during certain periods.
Because of the resetting of interest rates, ARMs are less likely than non-
adjustable rate securities of comparable quality and maturity to increase
significantly in value when market interest rates fall.

     Inverse Floaters - The Series listed above may invest in inverse floaters,
     ----------------                                                          
which are derivative mortgage securities. Inverse floaters are structured as a
class of security that receives distributions on a pool of mortgage assets and
whose yields move in the opposite direction of short-term interest rates,
sometimes, at an accelerated rate.  Inverse floaters may be issued by agencies
or instrumentalities of the U.S. Government, or by private issuers, including
savings and loan associations, mortgage banks, commercial banks, investment
banks and special purpose subsidiaries of the foregoing.  Inverse floaters have
greater volatility than other types of mortgage securities in which the Series
invest (with the exception of stripped mortgage securities).  Inverse floaters
may not be as liquid as other securities in which the Series may invest.

     Structured Notes - The Series listed above may invest in a broad category
     ----------------                                                         
of instruments known as "structured notes." These instruments are debt
obligations issued by industrial corporations, financial institutions or
governmental or 

                                      -34-
<PAGE>
 
international agencies. Traditional debt obligations typically obligate the
issuer to repay the principal plus a specified rate of interest. Structured
notes, by contrast, obligate the issuer to pay amounts of principal or interest
that are determined by reference to changes in some external factor or factors.
For example, the issuer's obligations could be determined by reference to
changes in the value of a commodity (such as gold or oil), a foreign currency,
an index of securities (such as the S&P 500 Index) or an interest rate (such as
the U.S. Treasury bill rate). In some cases, the issuer's obligations are
determined by reference to changes over time in the difference (or "spread")
between two or more external factors (such as the U.S. prime lending rate and
the London Inter-Bank Offering Rate). In some cases, the issuer's obligations
may fluctuate inversely with changes in an external factor or factors (for
example, if the U.S. prime lending rate goes up, the issuer's interest payment
obligations are reduced). In some cases, the issuer's obligations may be
determined by some multiple of the change in an external factor or factors (for
example, three times the change in the U.S. Treasury bill rate). In some cases,
the issuer's obligations remain fixed (as with a traditional debt instrument) so
long as an external factor or factors do not change by more than the specified
amount (for example, if the U.S. Treasury bill rate does not exceed some
specified maximum); but if the external factor or factors change by more than
the specified amount, the issuer's obligations may be sharply increased or
reduced.
    
     Structured notes can serve many different purposes in the management of the
Series.  For example, they can be used to increase the Series' exposure to
changes in the value of assets that the Series would not ordinarily purchase
directly (such as gold or oil).  They can also be used to hedge the risks
associated with other investments the Series holds.  For example, if a
structured note has an interest rate that fluctuates inversely with general
changes in market interest rates, the value of the structured note would
generally move in the opposite direction to the value of traditional debt
obligations, thus moderating the effect of interest rate changes in the value of
a Series' portfolio as a whole.      
    
     Structured notes involve special risks. As with any debt obligation,
structured notes involve the risk that the issuer will become insolvent or
otherwise default on its payment obligations. The risk is in addition to the
risk that the issuer's obligations (and thus the value of a Series' investment)
will be reduced because of changes in the external factor or factors to which
the obligations are linked. The value of structured notes will in many cases be
more volatile (that is, will change more rapidly or severely) than the value of
traditional debt instruments. Volatility will be especially high if the issuer's
obligations are determined by reference to some multiple of the change in the
external factor or factors. Many structured notes have limited or no liquidity,
so that a Series would be unable to dispose of the investment prior to maturity.
(The Series are not permitted to invest more than 15% of its net assets in
illiquid investments.) As with all investments, successful use of structured
notes depends in significant part on the accuracy of the subadviser's analysis
of the issuer's creditworthiness and financial prospects, and of the
subadviser's forecast as to changes in relevant economic and financial market
conditions and factors. In instances where the issuer of a structured note is a
foreign entity, the usual risks associated with investments in foreign
securities (described below) apply.     

     Loan Participations and Assignments - Strategic Bond may invest in fixed
     ------------------------------------                                    
and floating rate loans ("Loans") arranged through private negotiations between
a foreign sovereign entity and one or more financial institutions ("Lenders").
The Series may invest in such Loans in the form of participations in Loans
("Participations") and assignments of all or a portion of Loans from third
parties ("Assignments").  Participations typically will result in the Series
having a contractual relationship only with the Lender, not with the borrower.
The Series will have the right to receive payments of principal, interest and
any fees to which it is entitled only from the Lender selling the Participation
and only upon receipt by the Lender of the payments from the borrower.  In
connection with purchasing Participations, the Series generally will have no
right to enforce compliance by the borrower with the terms of the loan agreement
relating to the Loan, nor any rights of set-off against the borrower, and the
Series may not benefit directly from any collateral supporting the Loan in which
it has purchased the Participation.  As a result, the Series will assume the
credit risk of both the borrower and the Lender that is selling the
Participation.  In the event of the insolvency of the Lender selling a
Participation, the Series may be treated as a general creditor of the Lender and
may not benefit from any set-off between the Lender and the borrower.  When the
Series purchases Assignments from Lenders, the Series will acquire direct rights
against the borrower on the Loan, except that under certain circumstances such
rights may be more limited than those held by the assigning Lender.

     The Series may have difficulty disposing of Assignments and Participations.
Because the market for such instruments is not highly liquid, the Series
anticipates that such instruments could be sold only to a limited number of
institutional investors. The lack of a highly liquid secondary market may have
an adverse impact on the value of such instruments and will have an adverse
impact on the Series' ability to dispose of particular Assignments or
Participations in response to a specific economic event, such as deterioration
in the creditworthiness of the borrower.  The Series currently intends to treat
all investments in Participations and Assignments as illiquid.

     When-Issued Securities - The Series listed above may invest in when-issued
     ----------------------                                                    
securities. If the value of a "when-issued" security being purchased falls
between the time a Series commits to buy it and the payment date, the Series may
sustain a loss.  The risk of this loss is in addition to the Series' risk of
loss on the securities actually in its portfolio at the time.  In addition, when
the Series buys a security on a when-issued basis, it is subject to the risk
that market rates of interest will increase before the time the security is
delivered, with the result that the yield on the security delivered to the
Series may be lower than the yield available on other, comparable securities at
the time of delivery.  The Series will maintain assets in a segregated account
in an amount sufficient to satisfy its outstanding obligations to buy securities
on a "when-issued" basis.
    
     Forward Commitments - The Series listed above may purchase securities on a
     -------------------                                                    
forward commitment basis; that is, make contracts to purchase securities for a
fixed price at a future date beyond the customary three-day settlement period. A
Series is required to hold and maintain in a segregated account with the
custodian until three-days prior to settlement date, cash, or liquid assets in
amount sufficient to meet the purchase price. Alternatively, a Series may enter
into offsetting contracts for the forward sale of other securities it owns. The
purchase of securities on a forward commitment basis involves risk of loss if
the value of the security to be purchased declines prior to the settlement date.
Although a Series will generally purchase securities on a forward commitment
basis with the intention of acquiring such securities for its portfolio, a
Series may dispose of forward commitments prior to settlement if the subadviser
deems it appropriate to do so.      

     Investment Company Securities - The Series listed above, other than
     -----------------------------                                       
Investors and Research Managers, may invest up to 10% of their assets in
securities of other investment companies. Investors and Research Managers may
invest in other investment companies to the extent permitted by the 1940 Act.
Because of restrictions on direct investment by U.S. entities in certain
countries, a Series may choose to invest indirectly in such countries by
purchasing shares of another investment company that is permitted to invest in
such countries, which may be the most practical or efficient way for the Series
to invest in such countries. In other cases, where the Series' adviser or
subadviser desires to make only a relatively small investment in a particular
country, investing through an investment company that holds a diversified
portfolio in that country may be more effective than investing directly in
issuers in that country. As an investor in another investment company, a Series
will bear its share of the expenses of that investment company. These expenses
are in addition to the Series' own costs of operations. In some cases, investing
in an investment company may involve the payment of a premium over the value of
the assets held in that investment company's portfolio. Venture Value may only
invest in securities of investment companies investing primarily in foreign
securities.
    
     Domestic Equity Depositary Receipts are investment company securities;
therefore, investments therein are subject to a Series' limitations on
investment in other investment companies.      

     Short Sales "Against the Box"- The Series listed above may engage in short
     ----------------------------                                              
sales "against the box." A short sale is a transaction in which a party borrows
a security and then sells the borrowed security to another party.  The Series
may engage in short sales, but only if the Series owns (or has the right to
acquire without further consideration) the security it has sold short, a
practice known as selling short "against the box."  Short sales against the box
may protect the Series against the risk of losses in the value of its portfolio
securities because any unrealized losses with respect to such securities should
be wholly or partially offset by a corresponding gain in the short position.
However, any potential gains in such securities should be wholly or partially
offset by a corresponding loss in the short position.  Short sales against the
box may be used to lock in a profit on a security when, for tax reasons or
otherwise, a subadviser does not want to sell the security.

     Zero Coupon Securities - The Series listed above may invest in zero coupon
     ----------------------                                                    
securities.  Zero coupon securities involve special risk considerations.  Zero
coupon securities include debt securities that pay no cash income but are sold
at substantial discounts from their value at maturity.  When such a zero coupon
security is held to maturity, its entire return, which consists of the
amortization of discount, comes from the difference between its purchase price
and its maturity value. The difference is known at the time of purchase, so that
investors holding zero coupon securities until maturity know at the time of
their investment what the return on their investment will be.  Certain other
zero coupon securities which also are sold at substantial discounts from their
maturity value, provide for the commencement of regular interest payments at a
deferred date.

Zero coupon securities tend to be subject to greater price fluctuations in
response to changes in interest rates than are ordinary interest-paying debt
securities with similar maturities.  The values of zero coupon securities
appreciate more during periods of declining interest rates and depreciates more
during periods of rising interest rates.  Zero coupon securities may be issued
by a wide variety of corporate and governmental issuers.  Although zero coupon
securities are generally not traded on a national securities exchange, many such
securities are widely traded by brokers and dealers and, if so, will not be
considered illiquid.

                                      -36-
<PAGE>
 
Current federal income tax law requires the holder of a zero coupon security (as
well as the holders of other securities, such as Brady Bonds, which may be
acquired at a discount) to accrue income with respect to these securities prior
to the receipt of cash payments.  To maintain its qualification as a regulated
investment company and avoid liability for federal income and excise taxes, the
Series may be required to distribute income accrued with respect to these
securities and may have to dispose of portfolio securities under disadvantageous
circumstances in order to generate cash to satisfy these distribution
requirements.

                          RESOLVING MATERIAL CONFLICTS
    
   Currently, shares in the Fund are available only to separate accounts
established by New England Financial ("NEF"), MetLife or their subsidiaries 
as an investment vehicle for variable life insurance or variable annuity
products.  In the future, however, such shares may be offered to separate
accounts of insurance companies unaffiliated with NEF or MetLife.      

   A potential for certain conflicts of interest exists between the interests of
variable life insurance contract owners and variable annuity contract owners.
Pursuant to conditions imposed in connection with related regulatory relief
granted by the SEC, the Fund's Board of Trustees has an obligation to monitor
events to identify conflicts that may arise from the sale of shares to both
variable life insurance and variable annuity separate accounts or to separate
accounts of insurance companies not affiliated with NEF or MetLife.  Such events
might include changes in state insurance law or federal income tax law, changes
in investment management of any Series of the Fund or differences between voting
instructions given by variable life insurance and variable annuity contract
owners.  Insurance companies investing in the Fund will be responsible for
proposing and executing any necessary remedial action and the Board of Trustees
has an obligation to determine whether such proposed action adequately remedies
any such conflicts.

                       DETERMINATION OF NET ASSET VALUES

  The net asset value per share of each Series is determined as of the close of
regular trading on the New York Stock Exchange on each day the New York Stock
Exchange is open.  The New York Stock Exchange is currently expected to be
closed on weekend days and on the following holidays each year:  New Year's Day,
Martin Luther King Day, Presidents Day, Good Friday, Memorial Day, Independence
Day, Labor Day, Thanksgiving Day and Christmas Day.  Expenses of each Series are
paid or accrued each day.

All Series (other than Money Market)

  Each Series other than Money Market values its securities in the manner set
forth below.
    
  Equity securities traded on a national securities exchange or exchanges or the
NASDAQ National Market System are valued at their last sale price on the
principal trading market. Equity securities traded on a national securities
exchange or exchanges or on the NASDAQ National Market System for which there is
no reported sale during the day, and equity securities not so traded are valued
at the last reported bid price. Equity securities traded over-the-counter are
valued at the last reported bid price or at the average of the last reported bid
and asked price, according to the subadviser's valuation policies. Other equity
securities for which current market quotations are not readily available
(including restricted securities, if any) and all other assets are valued at
fair value as determined in good faith by the Series' adviser or subadviser
acting under the supervision of the Board of Trustees, although the actual
calculations may be made by a pricing service selected by the Series'adviser or
subadviser and approved by the Board. Such valuations are determined by using
methods based on market transactions for comparable securities and on various
relationships between securities that are generally recognized by institutional
traders.     
    
  Exchange traded and other fixed-income securities are valued at the last
reported sale price. Other fixed-income securities (other than short term
obligations maturing in 60 days or less, which are valued using the amortized
cost method which approximates market value) are valued on the basis of market
valuations furnished by a pricing service selected by the Series' adviser or
subadviser, pursuant to the authorization of the Board of Trustees. The pricing
service employed will be one that determines valuations of normal institutional-
sized trading units of long-term debt securities. Other securities for which
current market quotations are not available are valued at fair value as
determined in good faith by the Series' adviser or subadviser acting under the
supervision of the Board of Trustees, although the actual calculations may be
made by an approved pricing service. Such valuations are determined by using
methods based on market transactions for comparable securities and on various
relationships between securities that are generally recognized by institutional
traders.     
                                      -37-
<PAGE>
     
  An option purchased by a Series of the Fund generally will be valued at the
last sale price or, in the absence of the last price, the last offer price. 
     
    
  A futures contract will be valued at the unrealized gain or loss on the
contract to the current settlement price may not be used if the market makes a
limit move with respect to a particular futures contract or if the securities
underlying the futures contract experience significant price fluctuations after
determination of the settlement price. When settlement price is not used,
futures contracts will be valued at fair value as determined by the respective
adviser or subadviser, acting under the supervision of the Fund's Board of
Trustees.     
    
  Securities traded primarily on an exchange outside the United States which
closes before the close of the New York Stock Exchange generally will be valued
for purposes of calculating a Series' net asset value at the last sale price on
that non-U.S. exchange, except that when an occurrence after the closing of that
exchange may materially change such security's value, the respective adviser or
subadviser may value the security in good faith, acting under the supervision of
the Fund's Board of Trustees.      
    
  All other securities and assets of each Series are valued at their fair market
value as determined in good faith by the adviser or the subadviser of that
Series (or pricing service selected by the subadviser or by CGM) under the
supervision of the Fund's Board of Trustees.      
    
  The value of any assets for which the market price is expressed in terms of
foreign currency will be translated into U.S. dollars at the prevailing market
rate on the date of net asset value computation, or, if no such rate is quoted
at such time , at such other appropriate rate as may be determined by the
Series' adviser or subadviser, acting under the supervision of the Fund's Board
of Trustees. The U.S. dollar value of forward foreign currency contracts is
determined using forward currency exchange rates supplied by a quotation
service. All contracts are "marked-to-market" daily at the applicable
transaction rates, and any gains or losses are recorded for financial statement
purposes as unrealized until settlement date.      

          

Money Market

  The portfolio securities of Money Market will be valued at amortized cost.
Under the amortized cost method of valuation, securities are valued at cost on
the date of purchase.  Thereafter the values of securities purchased at a
discount or premium are increased or decreased incrementally each day so that at
maturity the purchase discount or premium is fully amortized and the value of
the security is equal to its principal amount.  Due to fluctuations in interest
rates, the amortized cost value of the securities of the Money Market may at
times be more or less than their market value.

          By using amortized cost valuation, the Money Market seeks to maintain
a constant net asset value of $100 per share despite minor shifts in the market
value of its portfolio securities.  The yield on a shareholder's investment may
be more or less than that which would be recognized if the net asset value per
share of the Money Market were not constant and were permitted to fluctuate with
the market value of the portfolio securities of the Series.  However, as a
result of the following procedures, the Fund believes any difference will
normally be minimal.  Quarterly, the Fund's Trustees monitor the deviation
between the net asset value per share of the Series as determined by using
available market quotations and its amortized cost price per share.  Back Bay
Advisors makes such comparisons at least weekly and will advise the Trustees
promptly in the event of any significant deviation.  If the deviation exceeds
0.50% the Board of Trustees will consider what action, if any, should be
initiated to provide fair valuation of the portfolio securities of Money Market
and prevent material dilution or other unfair results to shareholders.  Such
action may include selling portfolio securities prior to maturity, withholding
dividends or utilizing a net asset value per share as determined by using
available market quotations.

                               FUND PERFORMANCE
                            PERFORMANCE INFORMATION

   Information about the performance of the Series is set forth below and, from
time to time, the Fund may use this information in advertisements.  Performance
                                                                    -----------
information about a Series is based on that Series' past performance and is not
- -------------------------------------------------------------------------------
intended to indicate future performance.  The Fund serves as the underlying
- ----------------------------------------                                   
investment vehicle for variable life insurance or variable annuity products and
its shares cannot be purchased directly.  Therefore, such performance
 information does not reflect any of the charges assessed against the insurance
company separate accounts or the variable life insurance or variable annuity
products for which the Fund serves as an investment vehicle.

   Each Series may include its total return in advertisements or other written
material.  Total return is measured by comparing the value of a hypothetical
$1,000 investment in the Series at the beginning of the relevant period to the
value of the investment at the end of the period (assuming immediate
reinvestment of any dividends or capital gains distributions).  Total return
reflects the bearing or deferral of certain expenses by NEF or NEIM. If these
arrangements had not been in effect, certain Series' total return would have
been lower (see "Effect of Expense Deferrals and Limits" below).

Calculations of Yield and Total  Return
- ---------------------------------------

  Yield of the Balanced Series, Managed Series, Strategic Bond, Bond Income and
  -----------------------------------------------------------------------------
the U.S. Government  Series. The yield of each of these Series will be computed
- ---------------------------                                                    
in accordance with the SEC's standardized formula by annualizing net investment
income per share for a recent 30-day period and dividing that amount by a
share's net asset value (reduced by any earned income expected to be declared
shortly as a dividend) on the last trading day of that period.  Net investment
income will reflect amortization of any market value premium or discount of
fixed-income securities (except for obligations backed by mortgages or other
assets) and may include recognition of a pro rata portion of the stated dividend
rate of dividend paying portfolio securities.
    
  These Series' yields will vary from time to time depending upon market
conditions, the composition of the Series' portfolio and the operating expenses
of the Series.  These factors and possible differences in the methods used in
calculating yield should be considered when comparing the Series' yields to
yields published for other investment companies and other investment vehicles.
Yield should also be considered relative to changes in the value of the Series'
shares and to the relative risks associated with the investment objectives and
policies of the Series.  Yield information may be useful in reviewing such
Series' performance and providing a basis for comparison with other investment
alternatives, although the yields of the Series do not take into account any of
the fees imposed in connection with the purchase of variable life insurance
policies or variable annuity contracts offered by NEF or MetLife or their
affiliates.  Yield may be stated with or without giving effect to any expense
limitations in effect for the Series.      

  At any time in the future, yields may be higher or lower than past yields and
there can be no assurance that any historical results will continue.

  Investors are specifically advised that share prices, expressed as the net
asset value per share, will vary just as yields will vary. An investor's focus
on the yield of a Series to the exclusion of consideration of the share price
may result in the investor's misunderstanding the total return he or she may
derive from the Series.

For the 30-day period ending December 31, 1998, the Balanced, Managed, Strategic
Bond, Bond Income and U.S. Government Series had yields (calculated in
accordance with this section) of 2.28%, 3.44%, 0.21%, 0.47% and 0.47%,
respectively.

  Yield of Money Market. Money Market's yield represents the net change,
  ---------------------                                                 
exclusive of capital changes, in the value of a hypothetical account having a
balance of one share at the beginning of the period for which yield is
determined (the "base period"). Current yield for the base period (for example,
seven calendar days) is calculated by dividing (i) the net change in the value
of the account for the base period by (ii) the number of days in the base
period.  The resulting number is then multiplied by 365 in order to determine
such net change on an annualized basis.  This amount is divided by the value of
the account as of the beginning of the base period, normally $100, in order to
state the current yield as a percentage.  Yield may also be calculated on an
"effective" or a "compound" basis, which assumes continual reinvestment
throughout an entire year of net income earned at the same rate as net income is
earned by the account for the base period.  Yield is calculated without regard
to realized and unrealized gains and losses.  The yield of Money Market will
vary depending on prevailing interest rates, the operating expenses of Money
Market and the quality, maturity and type of instruments held in the portfolio
of Money Market.  Yield information may be useful in reviewing Money Market's
performance and providing a basis for comparison with other investment
alternatives, although the yield of Money Market does not take into account any
of the fees imposed in connection with the purchase of variable insurance
policies or variable annuity contracts offered by NEF or MetLife their
affiliates.  However, unlike certain bank deposits or other investments which
pay a fixed yield for a stated period of time, money market fund yields
fluctuate.  Consequently no yield quotation should be considered as
representative of what the yield of Money Market may be for any specified period
in the future.

For the seven day period ending December 31, 1998, Money Market had a  yield of
5.15% and an effective yield of 5.28%.
    
  Calculation of Total Return.  Total return is a measure of the change in value
  ---------------------------                                                  
of an investment in a Series over the period covered, which assumes that any
dividends or capital gain distributions are     

                                      -40-
<PAGE>
 
automatically reinvested in the Series rather than paid to the investor in cash.
Total return may be higher or lower than past performance, and there can be no
assurance that any historical results will continue.

  The formula for total return used by a Series includes three steps: (1) adding
to the total number of shares purchased by a hypothetical $1,000 investment in a
Series all additional shares that would have been purchased if all dividends and
distributions paid or distributed during the period had been automatically
reinvested; (2) calculating the value of the hypothetical initial investment as
of the end of the period by multiplying the total number of shares owned at the
end of the period by the net asset value per share on the last trading day of
the period; and (3) dividing this account value for the hypothetical investor by
the amount of the initial investment and annualizing the result for periods of
less than one year.  Total return reflects the bearing or deferral of certain
expenses by NEIM.   Total return would be lower for these Series if these
expense arrangements had not been in effect. Total return does not reflect
charges assessed against the insurance company separate accounts or the variable
life insurance or variable annuity products for which the Fund serves as an
investment vehicle.  Total return of a Series should only be considered along
with investment return information for those separate accounts or the variable
life insurance or variable annuity products.

Performance Comparisons

return in advertisements or in other written information furnished to present
and prospective owners of the variable life insurance and variable annuity
contracts supported by the Fund. Balanced, Managed, Bond Income, U.S.
Government, Strategic Bond and Money Market may, from time to time, also include
their yield in such advertisements or other written information.  These results
may include comparisons to the yields of money market funds reporting to
IBC/Donoghue's Money Fund Report ("Donoghue's Report").  In addition, each
Series may, from time to time, provide a ranking of such performance figures
relative to similar figures for mutual funds whose performance has been
monitored by Lipper Analytical Services, Inc. ("Lipper").  Performance
information about a Series is based on the Series' past performance and is not
intended to indicate future performance.

  Donoghue's Report is an independent service that collects data from over 1,000
money market funds weekly and reports on the assets, 7- and 30-day yields, 12-
month yields, average maturities and portfolio breakdowns of such funds.  12-
month yields represent total return assuming reinvestment of dividends for up to
one year.

                         EXPENSE DEFERRALS AND LIMITS

Voluntary Expense Agreement

Pursuant to the voluntary expense agreement relating to Small Cap, NEIM bears
all the operating expenses (does not include amortization of expenses, brokerage
costs, interest, taxes or extraordinary expenses) of the Series in excess of
1.00% of the Series' average daily net assets. NEIM may terminate this expense
agreement at any time. As a result of the current voluntary expense agreement
(and assuming the Series incur the same level of management fees as in 1998 and
no taxes, interest or extraordinary expenses), Small Cap's expense ratio during
this Prospectus' effectiveness, assuming the continuation of the voluntary
expense agreement, is expected to be 1.00% of the Series' average daily net
assets.

Expense Deferral Arrangement

   Pursuant to an expense deferral arrangement relating to the International
Equity, Equity Growth, Venture Value, Midcap Value, Balanced, Strategic Bond,
U.S. Government, Investors and Research Managers Series, NEIM has agreed to pay
the operating expenses (does not include amortization of expenses, brokerage
costs, interest, taxes, or extraordinary expenses) of the Series' operations in
excess of stated annual expense limits (based on a Series' then-current fiscal
year), which limits vary from Series to Series, subject to the obligation of the
Series to repay NEIM such expenses in future years, if any, when a Series'
expenses fall below the stated expense limit that pertains to that Series; such
deferred expenses may be charged to a Series in a subsequent year to the extent
that the charge does not cause the total expenses in such subsequent year to
exceed the Series' stated expense limit; provided, however, that no Series is
obligated to repay any expense paid by NEIM more than two years (three in the
case of Investors Series and Research Managers Series) after the end of the
fiscal year in which such expense was incurred. The expense deferral
arrangements can be prospectively discontinued by NEIM but any expenses that
were deferred while a

                                      -43-

Series' expense limit was in place can never be charged to that Series unless
that Series' expenses fall below the limit.  The expense limits (annual rates as
a percentage of each Series' net average daily net assets) are as follows:

Additional Information About Expenses

   Each Series pays all expenses not borne by its adviser or subadviser or New
England Securities, including, but not limited to, the charges and expenses of
each Series' custodian, independent auditors and legal counsel for the Fund and
its independent trustees, all brokerage commissions and transfer taxes in
connection with portfolio transactions, all taxes and filing fees, the fees and

     These expense figures do not include portfolio brokerage commissions, which
are not deducted from the Series' assets in the same manner as other charges and
expenses; rather, brokerage commissions are part of the purchase price paid for
portfolio securities and reduce the proceeds received on the sale of portfolio
securities.

         (a) Retired from service as a trustee of the Fund effective July 31,
             1998

      The Fund provides no pension or retirement benefits to trustees, but has
adopted a deferred payment arrangement under which each trustee may elect not to
receive fees from the Fund on a current basis but to receive in a subsequent
period an amount equal to the value that such fees would have if they had been
invested in each Series on the normal payment date for such fees.  As a result
of this method of calculating the deferred payments, each Series, upon making
the deferred payments, will be in the same financial position as if the fees had
been paid on the normal payment dates.
    
      At March 31, 1999, the officers and trustees of the Fund as a group owned
less than 1% of the outstanding shares of the Fund or any Series.

*Prior to May 1, 1997 the subadviser of International Equity was Draycott
Partners Ltd. and the subadvisory fee rate payable for the Series was 0.75% of
the first $10 million of the Series' average net assets, 0.60% of the next $40
million of such assets, 0.45% of such assets in excess of $50 million.

**Prior to May 1, 1996, the advisory fee rate for Equity Growth was 0.70% of
average net assets and the sub-advisory fee rate was 0.45% of the first $10
million of average net assets, 0.40% of the next $90 million of such assets,
0.35% of the next $150 million of such assets, 0.30% of the next $250 million of
such assets and 0.25% of such assets in excess of $500 million.  Effective May
1, 1996, Alger Management has agreed with NEIM (then , TNE Advisers) that the
sub-advisory fee payable by NEIM to Alger Management will be reduced by 0.05% of
the first $240 million of the excess of the Series' average daily net assets
over $10 million, and by 0.10% of the excess of the Series' average daily net
assets over $250 million.  This fee reduction benefits NEIM, but does not reduce
the advisory fees payable by the Series.  The fee reduction agreement will
expire at such time as NEIM has recovered certain expenses (generally, those
expenses borne by NEIM under the Expense Deferral Arrangement prior to January
1, 1996 which are not recovered from the Series).

***Prior to May 1, 1998, the subadviser of Midcap Value was Loomis Sayles, and
the subadvisory fee rate payable for the Series was 0.50% of the first $25
million of average daily net assets, 0.40% of the next $75 million of such
assets, 0.35% of the next $100 million of such assets, and 0.30% of such assets
in excess of $200 million.

  In connection with SBAM's service as subadviser to Strategic Bond, SBAM's
London based affiliate, SBAM Ltd. serves as subadviser to SBAM relating to
currency transactions and investments in non-dollar denominated debt securities
for the benefit of the Salomon Brothers Strategic Bond Opportunities Series.
For these services, SBAM has agreed to pay SBAM Ltd. one-third of the
compensation that SBAM receives for serving as subadviser to the Series.

  In connection with Davis Selected's service as subadviser to Venture Value,
Davis Selected may delegate any and all responsibilities to its New York based
subsidiary, DSA-NY.  As compensation to DSA-NY, Davis Selected will compensate
DSA-NY for all reasonable direct and indirect costs associated with DSA-NY's
performance of services provided to Davis Selected.

  For the fiscal years ended December 31, 1996, 1997, and 1998 each Series
(except Capital Growth) paid the following amounts in advisory fees to NEIM.

(1)  Prior to May 1, 1997, the Morgan Stanley International Magnum Equity Series
     was subadvised by Draycott Partners, Ltd. and was called the Draycott
     International Equity Series.

(2)  Prior to May 1, 1998, Midcap Value was subadvised by Loomis, Sayles &
Company, L.P. On January 28, 1998, the Board of Trustees approved a new
subadvisory agreement by and between TNE Advisers, Inc. (now NEIM) and Goldman
Sachs Asset Management, which was approved by shareholders on April 10, 1998.
The Series consequently changed its name from Loomis Sayles Avanti Growth Series
to Goldman Sachs Midcap Value Series.

   For the fiscal years ended December 31, 1996, 1997 and 1998, Capital Growth
paid CGM a total of $6,398,659, $8,434,722 and $10,272,927, respectively, in
advisory fees.

   Each advisory and subadvisory agreement provides that it will continue in
effect after two years from the date of its execution only if it is approved at
least annually thereafter (i) by the trustees of the Fund or by vote of a
majority of the outstanding voting securities of the applicable Series and (ii)
by vote of a majority of the trustees who are not interested persons of (i) the
Fund or (ii) the applicable Series' investment adviser or subadviser.  Except in
the case of the Strategic Bond, U.S. Government and Midcap Value, any amendment
to any advisory or subadvisory agreement must be approved by vote of a majority
of the outstanding voting securities of the applicable Series and by vote of a
majority of the trustees who are not interested persons of (i) the Fund or (ii)
the applicable Series' investment adviser or subadviser.  Each agreement may be
terminated without penalty by the trustees or by the shareholders of the
applicable Series, upon sixty days' written notice, or by the applicable Series'
investment adviser, upon ninety days' written notice, and each terminates
automatically in the event of its "assignment" as defined in the 1940 Act.  In
addition, each subadvisory agreement may be terminated without penalty upon
ninety days' written notice by the relevant subadviser.  Each advisory agreement
will automatically terminate if the Fund shall at any time be required by New
England Securities to eliminate all reference to the words "New England" in its
name, unless the continuance of such agreement after such change of name is
approved by a majority of the outstanding voting securities of the applicable
Series and by a majority of the trustees who are not interested persons of (i)
the Fund or (ii) the applicable Series' investment adviser or subadviser.

   Each advisory agreement provides that if the total ordinary business expenses
of a particular Series for any fiscal year exceed the lowest applicable
limitations (based on a percentage of average net assets or income) prescribed
by any state in which shares of that Series are qualified for sale, the
applicable Series' investment adviser shall pay such excess.  Each advisory
agreement provides, however, that the advisory fee shall not be reduced nor
shall any of such expenses be paid to an extent or under circumstances which
might result in the inability of any Series or of the Fund, taken as a whole, to
qualify as a regulated investment company under the Code.  The term "expenses"
for this purpose excludes brokerage commissions, taxes, interest and
extraordinary expenses.

   As required by state insurance licensing authorities, each Series' investment
adviser has also undertaken, separately from the advisory agreements, to be
liable for negligence in the performance of any administrative services with
respect to the Fund which are supplemental to their management of the investment
and reinvestment of that Series' assets.

   Each advisory and subadvisory agreement provides that the relevant investment
adviser or subadviser shall not be subject to any liability in connection with
the performance of its services thereunder in the absence of willful
misfeasance, bad faith, gross negligence or reckless disregard of its
obligations and duties.

   Certain officers and employees of Back Bay Advisors have responsibility for
portfolio management of the other advisory accounts and clients (including other
Series of the Fund and other registered investment companies, and accounts of
affiliates of Back Bay Advisors) that may invest in securities in which the
Series for which Back Bay Advisors acts as a subadviser may invest.  Where Back
Bay Advisors determines that an investment purchase or sale opportunity is
appropriate and desirable for more than one advisory account, purchase and sale
orders may be executed separately or may be combined and, to the extent
practicable, allocated by Back Bay Advisors to the participating accounts.

   Where advisory accounts have competing interests in a limited investment
opportunity, Back Bay Advisors will allocate an investment purchase opportunity
based on the relative time that competing accounts have had funds available for
investment, and the relative amounts of available funds, and will allocate an
investment sale opportunity based on relative cash requirements and the time
that the competing accounts have had investments available for sale.  It is Back
Bay Advisors' policy to allocate, to the extent practicable, investment
opportunities to each client over a period of time on a fair and equitable basis
relative to its other clients.

   It is believed that the ability of the Series for which Back Bay Advisors
acts as subadviser to participate in larger volume transactions in this manner
will in some cases produce better executions for the Series.  However, in some
cases, this 

                                      -52-
<PAGE>
 
procedure could have a detrimental effect on the price and amount of a security
available to a Series or the price at which a security may be sold. The trustees
are of the view that the benefits of retaining Back Bay Advisors as subadviser
outweigh the disadvantages, if any, that might result from participating in such
transactions.

   Certain officers of Loomis Sayles have responsibility for the management of
other client portfolios.  The Detroit office of Loomis Sayles buys and sell
portfolio securities for Small Cap.  The Pasadena office buys and sells
portfolio securities for the Balanced Series.  These and other offices of Loomis
Sayles buy securities independently of one another.  The other investment
companies and clients served by Loomis Sayles sometimes invest in securities in
which the Series advised by Loomis Sayles also invest.  If one of these Series
and such other clients advised by the same office of Loomis Sayles desire to buy
or sell the same portfolio securities at about the same time, purchases and
sales will be allocated, to the extent practicable, on a pro rata basis in
proportion to the amounts desired to be purchased or sold for each.  It is
recognized that in some cases the practices described in this paragraph could
have a detrimental effect on the price or amount of a security which that Series
purchases or sells.  In other cases, however, it is believed that these
practices may benefit the Series.  It is the opinion of the trustees of the Fund
that the desirability of retaining Loomis Sayles as subadviser for these Series
outweighs the disadvantages, if any, which might result from these practices.

   Certain officers of Westpeak have responsibility for portfolio management for
other clients (including affiliates of Westpeak), some of which may invest in
securities in which Growth and Income or Stock Index also may invest.  When
these Series and other clients desire to purchase or sell the same security at
or about the same time, the purchase and sale orders are ordinarily placed and
confirmed separately but may be combined to the extent practicable and allocated
as nearly as practicable on a pro rata basis in proportion to the amounts
desired to be purchased or sold for each.  It is believed that the ability of
those clients to participate in larger volume transactions will in some cases
produce better executions for Growth and Income and Stock Index.  However, in
some cases this procedure could have a detrimental effect on the price and
amount of a security available to a Series or the price at which a security may
be sold.  It is the opinion of the trustees of the Fund that the desirability of
retaining Westpeak as subadviser for Growth and Income and Stock Index outweighs
the disadvantages, if any, which might result from these practices.

   Various officers and trustees of the Fund also serve as officers or trustees
of other investment companies advised by CGM. The other investment companies and
clients served by CGM (including accounts of affiliates of CGM) sometimes invest
in securities in which Capital Growth also invests.  If Capital Growth and such
other investment companies or clients advised by CGM desire to buy or sell the
same portfolio securities at the same time, purchases and sales will be
allocated to the extent practicable on a pro rata basis in proportion to the
amounts desired to be purchased or sold for each.  It is recognized that in some
cases the practices described in this paragraph could have a detrimental effect
on the price or amount of the securities which Capital Growth purchases or
sells.  In other cases, however, it is believed that these practices may benefit
Capital Growth Series.  It is the opinion of the trustees that the desirability
of retaining CGM as adviser for Capital Growth outweighs the disadvantages, if
any, which might result from these practices.

   Certain officers and employees of SBAM, Davis Selected, MSAM, GSAM, Alger
Management and MFS have responsibility for portfolio management for other
clients (including other registered investment companies and affiliates of SBAM,
Davis Selected, MSAM, GSAM, Alger Management or MFS) some of which may invest in
securities in which the respective Series that these subadvisers manage also
invest.  In such circumstances, SBAM, Davis Selected, MSAM, GSAM, Alger
Management or MFS may determine that orders for the purchase or sale of the same
security for the Series it manages and one or more other registered investment
companies or other accounts it manages should be combined, in which event the
transactions will be priced and allocated in a manner deemed by SBAM, Davis
Selected, MSAM, GSAM, Alger Management or MFS, respectively, to be equitable and
in the best interests of the respective Series that it manages and its other
accounts.  It is recognized that in some cases the practices described in this
paragraph could have a detrimental effect on the price or amount of a security
that a Series purchases or sells.  In other cases, however, it is believed that
these practices may benefit a Series.  It is the opinion of the trustees that
the desirability of retaining SBAM, Davis Selected, MSAM, GSAM, Alger Management
and MFS as subadvisers for the respective Series outweighs the disadvantages, if
any, which might result from these practices.

                             DISTRIBUTION AGREEMENT

  Under an agreement with the Fund, New England Securities, a Massachusetts
corporation, serves as the general distributor of shares of each Series, which
are sold at net asset value without any sales charge.  The offering of each
Series' shares is continuous.  Shares are offered for sale only to certain
insurance company separate accounts.  New England Securities receives no
compensation from the Fund or purchasers of Fund shares for acting as
distributor.  The agreement does not obligate New England Securities to sell a
specific number of shares.  New England Securities is an indirect wholly-owned
subsidiary of NEF.

  New England Securities controls the words "New England" in the Fund's name and
if it should cease to be the Fund's distributor, the Fund may be required to
change its name and delete these words.  New England Securities also acts as
general distributor for New England Retirement Investment Account, NEVA, The New
England Variable Account, New England Variable Annuity Separate Account and New
England Variable Life Separate Account.

CGM and NEIM entered a new service agreement under which NEIM provides certain
administrative services to CGM.

     For the fiscal year ended December 31, 1996, under a Service Agreement

                      PORTFOLIO TRANSACTIONS AND BROKERAGE

  Some of the Fund's portfolio transactions are placed with brokers and dealers
who provide the investment advisers or subadvisers with supplementary investment
and statistical information or furnish market quotations to the Fund or other
investment companies advised by the investment advisers or subadvisers.
Although it is not possible to assign an exact dollar value to these services,
they may, to the extent used, tend to reduce the expenses of the investment
advisers or subadvisers.  The services may also be used by the investment
advisers or subadvisers in connection with their other advisory accounts and in
some cases may not be used with respect to the Fund.

Certain Portfolio Transactions of Balanced, Managed, Bond Income, Strategic
- ---------------------------------------------------------------------------
Bond, U.S. Government and Money Market Series
- ---------------------------------------------
    
  It is expected that the portfolio transactions of  Balanced, Managed, Bond
Income and Money Market in bonds, notes and money market instruments will
generally be with issuers or dealers on a net basis without a stated commission.
Portfolio turnover for the fiscal years ended December 31, 1996, 1997 and 1998
was 98%, 40% and 82%, respectively, for Bond Income; 72%, 65%, and 25%,
respectively, for Managed; 59%, 60% and 72%, respectively, for Balanced; 176%,
258% and 283%, respectively, for Strategic Bond; and 288%, 572% and 496%,
respectively, for U.S. Government.

  In placing orders for the purchase and sale of portfolio securities, CGM, in
the case of Capital Growth Series, GSAM,  in the case of the Midcap Value
Series, Loomis Sayles, in the case of the Small Cap and the Balanced Series,
Back Bay Advisors, in the case of investments in common stocks by the Managed
Series, MSAM, in the case of the International Equity Series, Davis Selected, in
the case of the Venture Value Series, Alger Management, in the case of 
Equity Growth and MFS, in the case of the Investors and Research Managers
Series, each selects only brokers which it believes are financially responsible,
will provide efficient and effective services in executing, clearing and
settling an order and will charge commission rates which, when combined with the
quality of the foregoing services, will produce best price and execution for the
transaction.  This does not necessarily mean that the lowest available brokerage
commission will be paid. However, the commissions are believed to be competitive
with generally prevailing rates.  The Series' advisers or subadvisers will use
their best efforts to obtain information as to the general level of commission
rates being charged by the brokerage community from time to time and will
evaluate the overall reasonableness of brokerage commissions paid on
transactions by reference to such data.  In making such evaluation, all factors
affecting liquidity and execution of the order, as well as the amount of the
capital commitment by the broker in connection with the order, are taken into
account.      
    
  For the fiscal years ending December 31, 1996, 1997 and 1998, Capital Growth
paid brokerage commissions of $4,124,163, $4,245,443 and $6,104,694,
respectively; Stock Index paid brokerage commissions of $9,955, $12,015 and
$18,326, respectively; the Managed Series paid brokerage commissions of $11,697,
$31,499 and $22,789, respectively; International Equity paid brokerage
commissions of $127,196, $146,747 and $163,946, respectively; Venture Value paid
brokerage commissions of $81,002, $148,966 and $280,521.84, respectively; and
Equity Growth paid brokerage commissions of $174,495, $489,199 and $694,292,
respectively.      

  For the fiscal years ending December 31, 1996, 1997 and 1998, Midcap Value
paid brokerage commissions of  $72,377, $74,700 and $371,572, respectively,  of
which $2,080, $1,300 and no dollars, respectively, were paid to brokers
providing research services.  For the same periods, Growth and Income paid
brokerage commissions of $106,927, $163,690 and $323,816, respectively, of which
$44,431, $77,711 and $157,952, respectively, were paid to brokers providing
research services.  For the same periods, Small Cap paid brokerage commissions
of $462,358, $394,066 and $711,187, respectively, of which $24, 045 $42,246 and
$71,282, respectively, were paid to brokers providing research services. For the
same periods, the Balanced Series paid brokerage commissions of $66,712,
$115,075 and $225,014, respectively, of which $7,006, $3,436 and $20,766,
respectively, were paid to brokers providing research services.

Growth and Income, Stock Index, Strategic Bond and U.S. Government Series
- -------------------------------------------------------------------------
    
  In placing orders for the purchase and sale of securities, the subadvisers for
the Series listed above always seeks best execution.  Westpeak and SBAM each
select only brokers or dealers which it believes are financially responsible,
will provide efficient and effective services in executing, clearing and
settling an order and will charge commission rates which, when combined with the
quality of the foregoing services, will produce best price and execution.  This
does not necessarily      

                                      -55-
<PAGE>
 
mean that the lowest available brokerage commission will be paid. Westpeak or
SBAM will each use its best efforts to obtain information as to the general
level of commission rates being charged by the brokerage community from time to
time and will evaluate the overall reasonableness of brokerage commissions paid
on transactions by reference to such data. In making such evaluation, factors
affecting liquidity and execution of the order, as well as the amount of the
capital commitment by the broker in connection with the order, are taken into
account. Westpeak or SBAM may cause the Series they manage to pay a broker-
dealer that provides brokerage and research services to Westpeak or SBAM an
amount of commission for effecting a securities transaction for a Series in
excess of the amount another broker-dealer would have charged effecting that
transaction. Westpeak or SBAM, as the case may be, must determine in good faith
that such 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 that particular transaction or Westpeak's or SBAM's overall
responsibilities to the Fund and its other clients. Westpeak's or SBAM's
authority to cause the Series it manages to pay such greater commissions is also
subject to such policies as the trustees of the Fund may adopt from time to
time.

Affiliated Brokerage
- --------------------
    
  A Series may pay brokerage commissions to an affiliated broker for acting as
the respective Series' agent on purchases and sales of securities for the
portfolio of the Series.  SEC rules require that commissions paid to an
affiliated broker of a mutual fund for portfolio transactions not exceed "usual
and customary" brokerage commissions.  The rules define "usual and customary"
commissions to include amounts which are "reasonable and fair" compared to the
commission, fee or other remuneration received or to be received by other
brokers in connection with comparable transactions involving similar securities
being purchased or sold on a securities exchange during a comparable period of
time."  The Trustees of the Fund, including those who are not "interested
persons" of the Fund, have adopted procedures for evaluating the reasonableness
of commissions paid to affiliated brokers and will review these procedures
periodically. Equity Growth paid $174,495, $489,199 and $694,292 in brokerage
commissions to Fred Alger and Company, Inc., an affiliated broker, for the
fiscal years ended December 31, 1996, 1997 and 1998, respectively.  The amount
paid by the Equity Growth represents approximately all of that Series' aggregate
brokerage commissions for the years ended December 31, 1996, 1997 and 1998.  For
the fiscal years ending December 31, 1996, 1997 and 1998, Venture Value paid a
total of $5,316, $54,840  and $40,044, respectively, in brokerage commissions to
Shelby Cullom Davis & Co., L.P., an affiliated broker.  This amount represents
6.6%, 36% and 14%, respectively, of such Series aggregate brokerage commissions
for such fiscal years.  For the fiscal years ended December 31, 1997 and 1998,
International Equity paid a total of $2,395 and $1,539 in brokerage commissions
to Morgan Stanley & Co. Incorporated, Morgan Stanley & Co. Limited, Morgan
Stanley Securities Limited and Dean Witter Reynolds Inc., each an affiliated
broker, representing 1.6% and 0.9%, respectively, of the total brokerage
commissions paid by such Series during such fiscal years. Midcap Value paid no
brokerage commissions to affiliates for the years ended December 31, 1996 and
1997. For the year ended December 31, 1998, Midcap Value paid 18.3% in brokerage
commissions to Goldman, Sachs & Co. which represents 4.9% of the total brokerage
commissions paid by such series during such fiscal year.      

                            DESCRIPTION OF THE FUND
    
  The Fund is a diversified, open-end management investment company registered
under the 1940 Act and was organized as a Massachusetts business trust under the
laws of Massachusetts pursuant to an Agreement and Declaration of Trust (the
"Declaration of Trust") dated December 16, 1986, as amended.  On February 27,
1987, the Fund succeeded to the operations of The New England Zenith Fund, Inc.,
a Massachusetts corporation incorporated on January 7, 1983 as NEL Series Fund,
Inc.  On November 1, 1985, the name of that corporation was changed to Zenith
Fund, Inc. and on July 17, 1986 it was changed again to The New England Zenith
Fund, Inc. Capital Growth, Bond Income and Money Market all commenced investment
operations in 1983. Stock Index commenced operations on March 30, 1987. The
Managed Series commenced investment operations on May 1, 1987. Midcap Value
(prior to May 1, 1998 the Series was named the Loomis Sayles Avanti Growth
Series) and the Growth and Income (prior to August 30, 1996 the Series was named
Westpeak Value Growth Series) commenced investment operations in April 1993.
Small Cap commenced investment operations on May 1, 1994. Equity Growth,
International Equity (prior to May 1, 1997 the Series was named the Draycott
International Equity Series), Venture Value, Balanced Series, Strategic Bond and
the U.S. Government Series commenced investment operations on October 31, 1994.
     
  The Declaration of Trust permits the Trustees to issue an unlimited number of
full and fractional shares of each of the Series.  Interests in the Fund
portfolios described in the Prospectus and in this Statement of Additional
Information are represented by shares of such Series.  Each share of a Series
represents an equal proportionate interest in such Series with 

                                      -56-
<PAGE>
 
each other share and is entitled to a proportionate interest in the dividends
and distributions from such Series. The shares of the Series do not have any
preemptive rights. Upon liquidation of any Series, whether pursuant to
liquidation of the Fund or otherwise, shareholders of such Series are entitled
to share pro rata in the net assets of such Series available for distribution to
shareholders. The Declaration of Trust also permits the trustees to charge
shareholders directly for custodial, transfer agency and servicing expenses.

  The Declaration of Trust also permits the Trustees, without shareholder
approval, to subdivide any series of shares into various sub-series of shares
with such dividend preferences and other rights as the trustees may designate.
While the trustees have no current intention to exercise this power, it is
intended to allow them to provide for an equitable allocation of the impact of
any future regulatory requirements which might affect various classes of
shareholders differently.  The trustees may also, without shareholder approval,
establish one or more additional separate portfolios for investments in the Fund
or merge two or more existing portfolios.  Shareholders' investments in such a
portfolio would be evidenced by a separate series of shares.

  The Declaration of Trust provides for the perpetual existence of the Fund.
The Fund or any Series, however, may be terminated at any time by vote of at
least two-thirds of the outstanding shares of each Series affected.  The
Declaration of Trust further provides that the Trustees may terminate the Fund
or any Series upon written notice to the shareholders thereof.

  The assets received by the Fund for the issue or sale of shares of each Series
and all income, earnings, profits, losses and proceeds therefrom, subject only
to the rights of creditors, are allocated to that Series, and constitute the
underlying assets of the Series.  The underlying assets of each Series are
segregated and are charged with the expenses in respect of that Series and with
a share of the general expenses of the Fund.  Any general expenses of the Fund
not readily identifiable as belonging to a particular Series are allocated by or
under the direction of the Trustees in such manner as the trustees determine to
be fair and equitable.  While the expenses of the Funds are allocated to the
separate books of account of each Series, certain expenses may be legally
chargeable against the assets of all Series.
    
  As of March 31, 1999, 100% of the outstanding voting securities of the Fund
were owned by separate accounts of MetLife and/or NEF, and may, from time to
time, be owned by those separate accounts and the general account of NEF and its
affiliates.  Therefore, MetLife and NEF are presumed to be in control (as that
term is defined in the 1940 Act) of the Fund. However, the staff of the SEC is
presently of the view that MetLife and NEF are each required to vote their Fund
shares that are held in a registered separate account (and, to the extent voting
privileges are granted by the issuing insurance company, in unregistered
separate accounts) in the same proportion as the voting instructions received
from owners of the variable life insurance or variable annuity contracts issued
by the separate account, and that MetLife and NEF each is required to vote any
shares held in general account (or in any unregistered separate account for
which voting privileges were not extended) in the same proportion as all other
Fund shares are voted.  MetLife and NEF currently intend to vote their shares in
a manner consistent with this view.      
    
  As of March 31, 1999, John Hancock Mutual Life Insurance Company, located at
200 Clarendon Street, Boston, Massachusetts 02117, was the beneficial owner
(through ownership units in a Separate Account) of 13.3% of Money Market.      

Voting Rights
- -------------

  Fund shareholders are entitled to one vote for each full share held (with
fractional votes for fractional shares held).  NEF and MetLife are the legal
owners of shares attributable to variable life insurance and variable annuity
contracts issued by their separate accounts, and have the right to vote those
shares.  Pursuant to the current view of the SEC staff, NEF and MetLife will
vote their shares in accordance with instructions received from owners of
variable life insurance and variable annuity contracts issued by separate
accounts that are registered under the 1940 Act.  All Fund shares held by
separate accounts of NEF and MetLife that are registered with the SEC (and, to
the extent voting privileges are granted by the issuing insurance company, by
unregistered separate accounts) for which no timely instructions are received
will be voted for, voted against, or withheld from voting on any proposition in
the same proportion as the shares held in that separate account for all
contracts for which voting instructions are received.  All Fund shares held by
the general investment account (or any unregistered separate account for which
voting privileges are not extended) of NEF and its affiliates will be voted in
the same proportion as the aggregate of (i) the shares for which voting
instructions are received and (ii) the shares that are voted in proportion to
such voting instructions are received.

  There will normally be no meetings of shareholders for the purpose of electing
trustees except that in accordance with the 1940 Act (i) the Fund will hold a
shareholders' meeting for the election of trustees at such time as less than a
majority of 

                                      -57-
<PAGE>
 
the trustees holding office have been elected by shareholders and (ii) if there
is a vacancy on the Board of Trustees, unless, after filling such vacancy, at
least two-thirds of the trustees holding office will have been elected by the
shareholders, such vacancy may only be filled by a vote of the shareholders. In
addition, trustees may be removed from office by a written consent signed by the
holders of two-thirds of the outstanding shares at a meeting duly called for the
purpose, which meeting shall be held upon the written request of the holders of
not less than 10% of the outstanding shares. Upon written request by the holders
of shares having a net asset value constituting 1% of the outstanding shares
stating that such shareholders wish to communicate with the other shareholders
for the purpose of obtaining the signatures necessary to demand a meeting to
consider removal of a trustee, the Fund has undertaken to provide a list of
shareholders or to disseminate appropriate materials (at the expense of the
requesting shareholders). Except as set forth above, the trustees shall continue
to hold office and may appoint successor trustees.

  No amendment may be made to the Declaration of Trust without the affirmative
vote of a majority of the outstanding shares of the Fund except (i) to change
the Fund's name or to cure technical problems in the Declaration of Trust and
(ii) to establish, designate or modify new and existing series of Fund shares or
other provisions relating to Fund shares in response to applicable laws or
regulations.

                                     TAXES

  The following discussion of federal income tax consequences is based on the
Code and the regulations issued thereunder as in effect on the date of this SAI.
New legislation, as well as administrative changes or court decisions, may
significantly change the conclusions expressed herein and may have a retroactive
effect with respect to the transactions contemplated herein.

  Each of the Series intends to qualify as a "regulated investment company"
("RIC") under Subchapter M of the Code.  A Series that is a RIC and distributes
to its shareholders at least 90% of its taxable net investment income
(including, for this purpose, its net realized short-term capital gains) and 90%
of its tax-exempt interest income (reduced by certain expenses), will not be
liable for federal income taxes to the extent its taxable net investment income
and its net realized long-term and short-term capital gains, if any, are
distributed to its shareholders.

  A number of technical rules are prescribed for computing net investment income
and net capital gains.  For example, a Series is generally treated as certain
foreign currency losses and capital losses arising after October 31 of a given
year may be treated as if they arise on the first day of the next taxable year.

  In order to qualify as a RIC under the Code, in addition to satisfying the
distribution requirement described above, each Series must (a) derive at least
90% of its gross income each taxable year from dividends, interest, payments
with respect to securities loans, gains from the sale or other disposition of
stock, securities, or foreign currencies, and certain other related income,
including generally, certain gains from options, futures, and forward contracts;
and (b) diversify its holdings so that, at the end of each fiscal quarter of the
Series' taxable year, (i) at least 50% of the market value of the Series' assets
is represented by cash and cash items, U.S. Government Securities, securities of
other RICs, and other securities, with such other securities limited, in respect
of any one issuer, to an amount that does not exceed 10% of the voting
securities of such issuer or 5% of the value of the Series' total assets; and
(ii) not more than 25% of the value of its assets is invested in the securities
(other than U.S. Government Securities and securities of other RICs) of any one
issuer or two or more issuers which the Series controls and which are engaged in
the same, similar or related trades or businesses.

  If a Series fails to qualify as a RIC for any year, all of its income will be
subject to tax at corporate rates, and its distributions (including capital gain
distributions) will be taxable as ordinary income dividends to its shareholders
to the extent of the Series' current and accumulated earnings and profits.

  In addition to qualifying under Subchapter M by meeting the requirements
described above, each Series intends to meet the diversification requirements of
Subchapter L of the Code so that non-qualified variable annuity contracts funded
by each Series will not fail to qualify as annuities for tax purposes.  In
general, for a Series to meet the investment diversification requirements of
Subchapter L of the Code, Treasury regulation 1.817-5 requires that, as of the
end of each fiscal quarter, no more than 55% of the total value of the assets of
the Series be represented by any one investment, no more than 70% by  any two
investments, no more than 80% by three investments and no more than 90% by four
investments.  Generally, for purposes of the regulations, all securities of the
same issuer are treated as one investment.  In the context of U.S. Government
securities (including any security that is issued, guaranteed or insured by the
United States or an instrumentality of the United 

                                      -58-
<PAGE>
 
States), each U.S. Government agency or instrumentality is treated as a separate
issuer. In the context of shares of registered investment companies, each
series, fund or portfolio is treated as a separate issuer.

  Notwithstanding the distribution requirement described above, which only
requires a Series to distribute at least 90% of its annual investment company
taxable income and does not require any minimum distribution of net capital
gain, a RIC is generally subject to a nondeductible 4% excise tax to the extent
it fails to distribute by the end of any calendar year at least 98% of its
ordinary income for the one-year period ending on October 31 of that year, plus
certain other amounts.

  The excise tax is inapplicable to any RIC all of the shareholders of which are
either tax-exempt pension trusts or separate accounts of life insurance
companies funding variable contracts.  Although each Series believes that it is
not subject to the excise tax, each Series believes that it is not subject to
the excise tax, each Series intends to make the distributions required to avoid
the imposition of the tax, provided such payments and distributions are
determined to be in the best interest of such Series' shareholders.

  Dividends declared by each Series in October, November, or December of any
year and payable to shareholders of record on a date in such month will be
deemed to have been paid by the Series and received by the shareholders on
December 31 of that year if paid by the Series at any time during the following
January.

                                 TRANSFER AGENT

   The transfer agent and the dividend paying agent for the Fund, NEF, located
501 Boylston Street, Boston, Massachusetts 02116, receives no remuneration from
the Fund in connection with its services as such.

  Under Massachusetts law shareholders could, under certain circumstances, be
held personally liable for the obligations of the Fund.  However, the
Declaration of Trust disclaims shareholder liability for acts or obligations of
the Fund and requires that notice of such disclaimer be given in each agreement,
obligation or instrument entered into or executed by the Fund or the trustees.
The Declaration of Trust provides for indemnification out of the relevant
Series' property for all loss and expense of any shareholder held personally
liable for the obligations of the Series in which the shareholder owns shares.
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 a Series itself would be unable to
meet its obligations. For purposes of such liability, the Fund's shareholders
are the separate accounts investing directly in the Fund and not the owners of
variable life insurance or variable annuity contracts or purchasers of other
insurance products.

  The Declaration of Trust further provides that the trustees will not be liable
for errors of judgment or mistakes of fact or law.  However, nothing in the
Declaration of Trust protects a trustee against any liability to which the
trustee would otherwise be subject by reason of willful misfeasance, bad faith,
gross negligence or reckless disregard of the duties involved in the conduct of
his or her office.  The By-Laws of the Fund provide for indemnification by the
Fund of the trustees and officers of the Fund except with respect to any matter
as to which any such person did not act in good faith in the reasonable belief
that his or her action was in or not opposed to the best interests of the Fund.
Such person may not be indemnified against any liability to the Fund or the
Fund's shareholders to which he or she would otherwise be subject by reason of
willful misfeasance, bad faith, gross negligence or reckless disregard of the
duties involved in the conduct of his or her office.

                          DESCRIPTION OF BOND RATINGS

Moody's Investors Service, Inc.

                                      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 edge".
Interest payments are protected by a large or by an exceptionally stable margin
and principal is secure.  While the various protective elements are likely to
change, such changes as can be visualized are most unlikely to impair the
fundamentally strong position of such issues.

                                       Aa
Bonds which are rated Aa are judged to be of high quality by all standards.
Together with the Aaa group they comprise what are generally known as high grade
bonds.  They are rated lower than the best bonds because margins of protection
may not be as large as in Aaa securities or fluctuations 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.  See Note 1.

                                       A
Bonds which are rated A possess many favorable investment attributes and are to
be considered as upper medium grade obligations.  Factors giving security to
principal and interest are considered adequate but elements may be present which
suggest a susceptibility to impairment sometime in the future.  See Note 1.

                                      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.  See Note 1.

                                       Ba
Bonds which are rated Ba are judged to have speculative elements; their future
cannot be considered as well assured.  Often, the protection of interest and
principal payments may be very moderate, and thereby not well safeguarded during
both good and bad times over the future.  Uncertainty of position characterizes
bonds in this class.

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

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

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

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

Should no rating be assigned by Moody's, the reason may be one of the following:

  (1) An application for rating was not received or accepted.

  (2) The issue or issuer belongs to a group of securities that are not rated as
a matter of policy.

                                      -60-
<PAGE>
 
  (3) There is a lack of essential data pertaining to the issue or issuer.

  (4) The issue was privately placed, in which case the rating is not published
in Moody's publications.
_________________

Note 1: This rating may include the numerical modifier 1, 2 or 3 to provide a
more precise indication of relative debt quality within the category, with 1
indicating the high end of the category, 2 the mid-range and 3 nearer the low
end.

Standard & Poor's Ratings Group

                                      AAA
This is the highest rating assigned by Standard & Poor's Corporation ("S&P") to
a debt obligation and indicates an extremely strong capacity to pay principal
and interest.

                                       AA
Bonds rated AA also qualify as high quality debt obligations. Capacity to pay
principal and interest is very strong, and in the majority of instances they
differ from AAA issues only in small degree.

                                       A
Bonds rated A have strong capacity to pay principal and interest although they
are somewhat more susceptible to the adverse effects of changes in circumstances
and economic conditions.

                                      BBB
Bonds rated BBB are regarded as having an adequate capacity to pay principal and
interest.  Whereas they normally exhibit protection parameters, adverse economic
conditions or changing circumstances are more likely to lead to a weakened
capacity to pay principal and interest for bonds in this category than for bonds
in the A category.

                                 BB, B, CCC, CC

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

                                       C
The rating C is reserved for income bonds on which no interest is being paid.

                                       D
Bonds rated D are in default, and payment of interest and/or repayment of
principal is in arrears.

Plus (+) or Minus (-):  The ratings from "AA" to "B" may be modified by the
addition of a plus or minus sign to show relative standing within the major
rating categories.

                                  APPENDIX A-2
                    DESCRIPTION OF COMMERCIAL PAPER RATINGS

Standard & Poor's Corporation

                                      A-1
Commercial paper rated A-1 by S&P has the following characteristics:  Liquidity
ratios are adequate to meet cash requirements.  Long-term senior debt is rated
"A" or better.  The issuer has access to at least two additional channels of
borrowing.  Basic earnings and cash flow have an upward trend with allowance
made for unusual circumstances.  Typically, the issuer's industry is well
established and the issuer has a strong position within the industry.  The
reliability and quality of management are unquestioned.  Commercial paper within
the A-1 category which has overwhelming safety characteristics is denoted "A-
1+."

                                      A-2
Capacity for timely payment on issues with this designation is strong.  However,
the relative degree of safety is not as overwhelming as for issues designated A-
1.

Moody's Investors Service, Inc.

                                      P-1
The rating P-1 is the highest commercial paper rating assigned by Moody's
Investors Service, Inc. ("Moody's").  Among the factors considered by Moody's in
assigning ratings are the following:

  (1) evaluation of the management of the issuer;

  (2) economic evaluation of the issuer's industry or industries and an
appraisal of speculative-type risks which may be inherent in certain areas;

  (3) evaluation of the issuer's products in relation to competition and
customer acceptance;

  (4) liquidity;

  (5) amount and quality of long-term debt;

  (6) trend of earnings over a period of ten years;

  (7) financial strength of a parent company and the relationships which exist
with the issuer; and

  (8) recognition by the management of obligations which may be present or may
arise as a result of public interest questions and preparations to meet such
obligations.

                                      P-2
Issuers rated P-2 have a strong capacity for repayment of short-term promissory
obligations.  This will normally be evidenced by many of the characteristics
cited above but to a lesser degree.  Earnings trends and coverage ratios, while
sound, will be more subject to variation.  Capitalization characteristics, while
still appropriate, may be more affected by external conditions.  Ample
alternative liquidity is maintained.

Item 25.  Indemnification
          ---------------   

          See Article 4 of the Fund's By-Laws filed as Exhibit 2 to
          Post-Effective Amendment No. 8 on Form N-1A (File No. 2-83538)
          which Exhibit is incorporated herein by reference. In addition,
          the Fund maintains a trustees and officers liability insurance
          policy with a maximum coverage of $15 million under which the Fund
          and its trustees and officers are named insureds.

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

                            DISTRIBUTION AGREEMENT
                            ----------------------


     AGREEMENT made as of the 28th day of April, 1999 by and between NEW ENGLAND
ZENITH FUND, a Massachusetts business trust (the "Fund"), and NEW ENGLAND
SECURITIES CORPORATION, a Massachusetts corporation (the "Distributor").

                              W I T N E S S E T H:

     In consideration of the covenants hereinafter contained the Fund and the
Distributor agree as follows:

     1.   Distributor.  The Fund hereby appoints the Distributor as general
          -----------                                                      
distributor of each series of shares of beneficial interest (each, a "Series")
of the Fund during the term of this Agreement.  The Fund reserves the right,
however, to refuse at any time or times to sell any Series shares hereunder for
any reason deemed adequate by the Board of Trustees of the Fund.

     2.   Sales.  The Distributor shall be under no obligation to effectuate any
          -----                                                                 
particular amount of sales of Series shares or to promote or make sales except
to the extent the Distributor deems advisable.

     3.   Net Asset Value Per Share.  All subscriptions and sales of a Series'
          -------------------------                                           
shares by the Distributor hereunder shall be at net asset value per share in
accordance with the provisions of the Agreement and Declaration of Trust and By-
laws and the then-current prospectus and statement of additional information
("Prospectus") of the Series.  No commission or other compensation for selling
or obtaining subscriptions for Series shares shall be paid by the Fund or
charged as a part of the subscription or selling price on any such sale or
subscription.

     4.   Fund Issuance of Series Shares.  The delivery of Series shares shall
          ------------------------------                                      
be made promptly by a credit to a shareholder's open account for the applicable
Series.  The Fund reserves the right (a) to issue Series shares at any time
directly to the shareholders of the particular Series as a share dividend or
share split, (b) to issue to such shareholders shares of the particular Series,
or rights to subscribe to shares of such Series, as all or part of any dividend
that may be distributed to shareholders of such Series or as all or part of any
optional or alternative dividend that may be distributed to shareholders of such
Series and (c) to sell Series shares in accordance with the current applicable
Prospectus of the Fund.
 
     5.   Repurchase.  The Distributor shall act as agent for the Fund in
          ----------                                                     
connection with the repurchase of Series shares by the Fund to the extent and
upon the terms and conditions set forth in the current applicable Prospectus of
the Series, and the Fund agrees to reimburse the Distributor, from time to time
upon demand, for any reasonable expenses incurred in connection with such
repurchases.

     6.   Undertaking Regarding Sales.  The Distributor shall use reasonable
          ---------------------------                                       
efforts to sell Series shares but does not agree hereby to sell any specific
number of Series shares and shall be 
<PAGE>
 
free to act as distributor of the shares of other investment companies. Series
shares will be sold by the Distributor only against orders therefor. The
Distributor shall not purchase Series shares from anyone except in accordance
with Section 5 hereof and shall not take "long" or "short" positions in Series
shares contrary to the Agreement and Declaration of Trust or By-laws of the
Fund. Series shares shall be issued by the Fund, after payment therefor has been
credited to the account of such Series.

     7.   Compliance.  The Distributor shall conform to the Rules of Fair
          ----------                                                     
Practice and other applicable rules of the National Association of Securities
Dealers, Inc. and NASD Regulation, Inc., and any applicable laws relating to the
sale of securities of any jurisdiction in which it sells, directly or
indirectly, any Series shares.  The Distributor agrees to make timely filings
with the Securities and Exchange Commission ("SEC") in Washington, D.C., the
National Association of Securities Dealers, Inc. and such other regulatory
authorities as may be required, of any sales literature relating to the Fund and
intended for distribution to prospective investors.  The Distributor also agrees
to furnish to the Fund sufficient copies of any agreements or plans it intends
to use in connection with any sales of Series shares in adequate time for the
Fund to file and clear them with the proper authorities before they are put in
use (which the Fund agrees to use its best efforts to do as expeditiously as
reasonably possible), and not to use them until so filed and cleared.

     8.   Registration and Qualification of Series Shares.  The Fund agrees to
          -----------------------------------------------                     
execute such papers and to do such acts and things as shall from time to time be
reasonably requested by the Distributor for the purpose of qualifying and
maintaining qualification of the Series shares for sale under the so-called Blue
Sky Laws of any state or for maintaining the registration of the Fund and of the
Series shares under the federal Securities Act of 1933 and the federal
Investment Company Act of 1940 (the "1940 Act"); to the end that there will be
available for sale from time to time such number of Series shares as the
Distributor may reasonably be expected to sell.  The Fund shall advise the
Distributor promptly of (a) any action of the Securities and Exchange Commission
or any authorities of any state or territory, of which it may be advised,
affecting registration or qualification of the Fund or the Series shares, or
rights to offer the Series shares for sale, and (b) the happening of any event
which makes untrue any statement, or which requires the making of any change, in
the registration statement or Prospectus of the Fund in order to make the
statements therein not misleading.

     9.   Distributor Independent Contractor.  The Distributor shall be an
          ----------------------------------                              
independent contractor.  The Distributor is responsible for its own conduct and
the employment, control and conduct of its agents and employees and for injury
to such agents or employees or to others through its agents or employees.  The
Distributor assumes full responsibility for its agents and employees under
applicable statutes and agrees to pay all employer taxes thereunder.

     10.  Interests in and of Distributor.  It is understood that any of the
          -------------------------------                                   
shareholders, trustees, officers, employees and agents of the Fund may be a
shareholder, director, trustee, officer, employee or agent of, or be otherwise
interested in, the Distributor, any affiliated person 

                                      -2-
<PAGE>
 
of the Distributor, any organization in which the Distributor may have an
interest or any organization which may have an interest in the Distributor; that
the Distributor, any such affiliated person or any such organization may have an
interest in the Fund; and that the existence of any such dual interest shall not
affect the validity hereof or of any transactions hereunder except as otherwise
provided in the Agreement and Declaration of Trust or By-laws of the Fund and
the articles of organization or by-laws of the Distributor, or by specific
provision of applicable law.

     11.  Words "New England" and Logo.  New England Life Insurance Company, an
          ----------------------------                                         
indirect parent company of the Distributor, has a proprietary interest in the
words "New England," "New England Financial" and the ship and NEF logos, any of
which may be used by the Fund only with the consent of the Distributor, which is
authorized by New England Life Insurance Company to give such consent as
provided herein.  The Distributor consents to the use by the Fund of the name
"New England Zenith Fund" or any other name embodying the words "New England"
and of New England Life Insurance Company's ship or NEF logos, in such forms as
the Distributor shall in writing approve, but only on condition and so long as
(i) this Agreement shall remain in full force and (ii) the Fund shall fully
perform, fulfill and comply with all provisions of this Agreement expressed
herein to be performed, fulfilled or complied with by it.  No such name shall be
used by the Fund at any time or in any place or for any purpose or under any
conditions except as in this section provided.  The foregoing authorization by
the Distributor as agent of New England Life Insurance Company to the Fund to
use said words and logos as part of a business or name is not exclusive of the
rights of the Distributor itself to use, or to authorize others to use, the
same; the Fund acknowledges and agrees that as between the Distributor and the
Fund, the Distributor has the exclusive right so to use, or authorize others to
use, said words and logos, and the Fund agrees to take such action as may
reasonably be requested by the Distributor to give full effect to the provisions
of this section (including, without limitation, consenting to such use of said
words and logos).  Without limiting the generality of the foregoing, the Fund
agrees that, upon any termination of this Agreement by either party or upon the
violation of any of its provisions by the Fund, the Fund will, at the request of
the Distributor made within six months after the Distributor has knowledge of
such termination or violation, use its best efforts to change the name of the
Fund so as to eliminate all reference, if any, to the words "New England" and
will not thereafter transact any business in a name containing the words "New
England" in any form or combination whatsoever, or designate itself as the same
entity as or successor to an entity of such name, or otherwise use the words
"New England" or any other reference to the Distributor.  Such covenants on the
part of the Fund shall be binding upon it, its trustees, officers, shareholders
and creditors and all other persons claiming under or through it.

     12.  Effective Date and Termination.  This Agreement shall become effective
          ------------------------------

     (a)  Unless otherwise terminated, this Agreement shall continue in effect
          with respect to the shares of each Series so long as such continuation
          is specifically approved

          of the Fund who are not interested persons of the Distributor or the
          Fund, cast in person at a meeting called for the purpose of voting on
          such approval.

     (b)  This Agreement may at any time be terminated with respect to the
          shares of any Series on sixty days' notice to the Distributor either
          by vote of a majority of the Fund's Board of Trustees then in office
          or by the vote of a majority of the votes which may be cast by
          shareholders of that Series.

     (c)  This Agreement shall automatically terminate in the event of its
          assignment.

     (d)  This Agreement may be terminated by the Distributor on ninety days'
          written notice to the Fund.

     Termination of this Agreement pursuant to this section shall be without
payment of any penalty.

     13.  Definitions.  For purposes of this Agreement, the following
          -----------

          entitled to vote at such meeting are present; or (2) the vote of the
          holders of more than 50% of the outstanding shares of such Series

          shall have their respective meanings as defined in the 1940 Act
          subject, however, to such exemptions as may be granted by the SEC
          under the 1940 Act.

     14.  Amendment.  This Agreement may be amended at any time with respect to
          ---------                                                            
the shares of any Series by mutual consent of the parties, provided that such
consent on the part of the Series shall be approved (i) by the Board of Trustees
of the Fund or by vote of a majority of the votes which may be cast by
shareholders of such Series and (ii) by a vote of a majority of the Board of
Trustees of the Fund who are not interested persons of the Distributor or the
Fund cast in person at a meeting called for the purpose of voting on such
approval.

     15.  Applicable Law and Liabilities.  This Agreement shall be governed by
          ------------------------------

                              April 28, 1999   




New England Zenith Fund
501 Boylston Street
Boston, Massachusetts 02116

Ladies and Gentlemen:
    
     You have informed us that you propose to offer and sell from time to time
shares ("Shares") of beneficial interest registered under the Securities Act of
1933, as amended (the "Act"), without par value, of your Back Bay Advisors Money
Market Series, Back Bay Advisors Bond Income Series, Capital Growth Series,
Westpeak Stock Index Series, Back Bay Advisors Managed Series, Westpeak Growth
and Income Series, Goldman Sachs Midcap Value Series, Loomis Sayles Small Cap
Series, Loomis Sayles Balanced Series, Morgan Stanley International Magnum
Equity Series, Salomon Brothers U.S. Government Series, Salomon Brothers
Strategic Bond Opportunities Series, Davis Venture Value Series, Alger Equity
Growth Series, MFS Investors Series and MFS Research Managers Series
("Series"), at not less than net asset value.      

     We have examined an executed copy of your Agreement and Declaration of
Trust dated December 16, 1986, as amended by Amendments Nos. 1 through 10
thereto (the "Declaration of Trust"), and are familiar with the action taken by
your trustees to authorize the issue and sale to the public from time to time of
authorized and unissued Shares.  We have further examined a copy of your By-Laws
and such other documents and records as we have deemed necessary for the purpose
of this opinion.

     Based on the foregoing, we are of the opinion that:

     1. The beneficial interest in each of your Series is divided into an
unlimited number of Shares.

     2. The issue and sale of the authorized but unissued Shares has been duly
authorized under Massachusetts law.  Upon the original issue and sale of any of
such authorized but unissued Shares and upon receipt of the authorized
consideration therefor in an amount not less than the applicable net asset
value, the Shares so issued will be validly issued, fully paid and nonassessable
by the Trust.

     The Trust is an entity of the type commonly known as a "Massachusetts
business trust." Under Massachusetts law, shareholders could, under certain
circumstances, be held personally liable for the obligations of the Trust.
However, the Declaration of Trust disclaims shareholder liability for acts or
obligations 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 its trustees. The Declaration of Trust provides for indemnification out of
the property of each Series for all loss and expense of any shareholder of such
Series held personally liable solely by reason of his or her being or having
been such a shareholder.  Thus, the risk of a shareholder incurring financial
loss on account of shareholder liability is limited to circumstances in which
such Series itself would be unable to meet its obligations.

     We understand that this opinion is to be used in connection with the
registration of an indefinite number of Shares for offering and sale pursuant to
the Act.  We consent to the filing of this opinion with and as part of your
Registration Statement on Form N-1A (File No. 2-83538) relating to such offering
and sale.

                              Very truly yours,

                              /s/ Ropes & Gray

                            NEW ENGLAND ZENITH FUND

                              ADVISORY AGREEMENT
                            (MFS Investors Series)

     AGREEMENT made as of this 28th day of April, 1999 by and between New
England Zenith Fund, a Massachusetts business trust (the "Fund"), with respect
to its MFS Investors Series (the "Series"), and New England Investment
Management, Inc., a Massachusetts corporation (the "Manager").

                                  WITNESSETH:

     WHEREAS, the Fund and the Manager wish to enter into an agreement setting
forth the terms upon which the Manager (or certain other parties acting pursuant
to delegation from the Manager) will perform certain services for the Series;

     NOW THEREFORE, in consideration of the premises and covenants hereinafter
contained, the parties agree as follows:

     1. (a)   The Fund hereby employs the Manager to furnish the Fund with
Portfolio Management Services (as defined in Section 2 hereof) and
Administrative Services (as defined in Section 3 hereof), subject to the
authority of the Manager to delegate any or all of its responsibilities
hereunder to other parties as provided in Sections 1(b) and (c) hereof. The
Manager hereby accepts such employment and agrees, at its own expense, to
furnish such services (either directly or pursuant to delegation to other
parties as permitted by Sections 1(b) and (c) hereof) and to assume the
obligations herein set forth, for the compensation herein provided.  The Manager
shall, unless otherwise expressly provided or authorized, have no authority to
act for or represent the Fund in any way or otherwise be deemed an agent of the
Fund.

     (b)   The Manager may delegate any or all of its responsibilities hereunder
with respect to the provision of Portfolio Management Services (and assumption
of related expenses) to one or more other parties (each such party, a "Sub-
Adviser"), pursuant in each case to a written agreement with such Sub-Adviser
that meets the requirements of Section 15 of the Investment Company Act of 1940
and the rules thereunder (the "1940 Act") applicable to contracts for service as
an investment adviser of a registered investment company (including, without
limitation, the requirements for approval by the trustees of the Fund and the
shareholders of the Series), subject, however, to such exemptions as may be
granted by the Securities and Exchange Commission.  Any Sub-Adviser may (but
need not) be affiliated with the Manager.  If different Sub-Advisers are engaged
to provide Portfolio Management Services with respect to different segments of
the portfolio of the Series, the Manager shall determine, in the manner
described in the prospectus of the Series from time to time in effect, what
portion of the assets belonging to the Series shall be managed by each Sub-
Adviser.
<PAGE>
 
     (c)   The Manager may delegate any or all of its responsibilities hereunder
with respect to the provision of Administrative Services to one or more other
parties (each such party, an "Administrator") selected by the Manager.  Any
Administrator may (but need not) be affiliated with the Manager.

     2.    As used in this Agreement, "Portfolio Management Services" means
management of the investment and reinvestment of the assets belonging to the
Series, consisting specifically of the following:

           (a)   obtaining and evaluating such economic, statistical and
     financial data and information and undertaking such additional investment
     research as shall be necessary or advisable for the management of the

           (b)   taking such steps as are necessary to implement the investment
     policies of the Series by purchasing and selling of securities, including
     the placing of orders for such purchase and sale; and

           (c)   regularly reporting to the Board of Trustees of the Fund with
     respect to the implementation of the investment policies of the Series.

     3.    As used in this Agreement, "Administrative Services" means the
provision to the Fund, by or at the expense of the Manager, of the following:

     time to time by the Fund and the Manager, and all necessary office
     supplies, facilities and equipment;

           (b)   necessary executive and other personnel for managing the
     affairs of the Series, including personnel to perform clerical,
     bookkeeping, accounting, stenographic and other office functions (exclusive
     of those related to and to be performed under contract for custodial,
     transfer, dividend and plan agency services by the entity or entities
     selected to perform such services);

           (c)   compensation, if any, of trustees of the Fund who are
     directors, officers or employees of the Adviser, any Sub-Adviser or any
     Administrator or of any affiliated person (other than a registered
     investment company) of the Manager, any Sub-Adviser or any Administrator;

           (d)   all services, other than services of counsel, required in
     connection with the preparation of registration statements and
     prospectuses, including amendments and revisions thereto, all annual,
     semiannual and periodic reports, and notices and proxy solicitation

<PAGE>
 
     regulatory authorities, to the extent that any such materials relate to the
     business of the Series, to the shareholders thereof or otherwise to the
     Series, the Series to be treated for these purposes as a separate legal
     entity and fund; and

           (e)   supervision and oversight of the Portfolio Management Services
     provided by each Sub-Adviser, and oversight of all matters relating to
     compliance by the Fund with applicable laws and with the Fund's investment
     policies, restrictions and guidelines, if the Manager has delegated to one
     or more Sub-Advisers any or all of its responsibilities hereunder with
     respect to the provision of Portfolio Management Services.

     4.    Nothing in section 3 hereof shall require the Manager to bear, or to
reimburse the Fund for:

           (a)   any of the costs of printing and mailing the items referred to
     in sub-section (d) of this section 3;

           (b)   any of the costs of preparing, printing and distributing sales

           (c)   compensation of trustees of the Fund who are not directors,
     officers or employees of the Manager, any Sub-Adviser or any Administrator
     or of any affiliated person (other than a registered investment company) of

           (d)   registration, filing and other fees in connection with

           (g)   charges and expenses of any transfer agents and registrars
     appointed by the Fund;

           (h)   brokers' commissions and issue and transfer taxes chargeable to
     the Fund in connection with securities transactions to which the Fund is a
     party;

           (i)   taxes and fees payable by the Fund to federal, state or other
     governmental agencies;

           (j)   any cost of certificates representing shares of the Fund;

                                      -3-
<PAGE>
 
           (k)   legal fees and expenses in connection with the affairs of the
     Fund including registering and qualifying its shares with federal and state
     regulatory authorities;

           (l)   expenses of meetings of shareholders and trustees of the Fund;
     and

           (m)   interest, including interest on borrowings by the Fund.

     5.    All activities undertaken by the Manager or any Sub-Adviser or
Administrator pursuant to this Agreement shall at all times be subject to the
supervision and control of the Board of Trustees of the Fund, any duly
constituted committee thereof or any officer of the Fund acting pursuant to like
authority.

     6.    The services to be provided by the Manager and any Sub-Adviser or
Administrator hereunder are not to be deemed exclusive and the Manager and any
Sub-Adviser or Administrator shall be free to render similar services to others,
so long as its services hereunder are not impaired thereby.

     7.    As full compensation for all services rendered, facilities furnished
and expenses borne by the Manager hereunder, the Fund shall pay the Manager
compensation at the annual rate of 0.75% of the Series' average daily net
assets.  Such compensation shall be payable monthly in arrears or at such other
intervals, not less frequently than quarterly, as the Board of Trustees of the
Fund may from time to time determine and specify in writing to the Manager.  The
Manager hereby acknowledges that the Fund's obligation to pay such compensation
is binding only on the assets and property belonging to the Series.

     8.    If the total of all ordinary business expenses of the Fund as a whole
(including investment advisory fees but excluding taxes and portfolio brokerage
commissions) for any fiscal year exceeds the lowest applicable percentage of
average net assets or income limitations prescribed by any state in which shares
of the Series are qualified for sale, the Manager shall pay such excess. Solely
for purposes of applying such limitations in accordance with the foregoing
sentence, the Series and the Fund shall each be deemed to be a separate fund
subject to such limitations.  Should the applicable state limitation provisions
fail to specify how the average net assets of the Fund or belonging to the
Series are to be calculated, that figure shall be calculated by reference to the
average daily net assets of the Fund or the Series, as the case may be.

     9.    It is understood that any of the shareholders, trustees, officers,
employees and agents of the Fund may be a shareholder, director, officer,
employee or agent of, or be otherwise interested in, the Manager, any affiliated
person of the Manager, any organization in which the Manager may have an
interest or any organization which may have an interest in the Manager; that the
Manager, any such affiliated person or any such organization may have an
interest in the Fund; and that the existence of any such dual interest shall not
affect the validity hereof or of any transactions hereunder except as 

                                      -4-
<PAGE>
 
otherwise provided in the agreement and declaration of trust of the Fund, the
articles of organization of the Manager or specific provisions of applicable
law.

     10.   This Agreement shall become effective as of the date of its
execution, and

           (a)   unless otherwise terminated, this Agreement shall continue in
     effect for two years from the date of execution, and from year to year
     thereafter so long as such continuance is specifically approved at least
     annually (i) by the Board of Trustees of the Fund or by vote of a majority
     of the outstanding voting securities of the Series, and (ii) by vote of a
     majority of the trustees of the Fund who are not interested persons of the
     Fund or the Manager, cast in person at a meeting called for the purpose of
     voting on, such approval;

           (b)   this Agreement may at any time be terminated on sixty days'
     written notice to the Manager either by vote of the Board of Trustees of
     the Fund or by vote of a majority of the outstanding voting securities of
     the Series;

           (c)   this Agreement shall automatically terminate in the event of
     its assignment;

           (d)   this Agreement may be terminated by the Manager on ninety days'
     written notice to the Fund;

           (e)   if New England Securities Corporation, the Fund's principal
     underwriter, requires the Fund or the Series to change its name so as to
     eliminate all references to the words "New England" pursuant to the
     provisions of the Fund's Distribution Agreement relating to the Series with
     said principal underwriter, this Agreement shall automatically terminate at
     the time of such change unless the continuance of this Agreement after such
     change shall have been specifically approved by vote of a majority of the
     outstanding voting securities of the Series and by vote of a majority of
     the trustees of the Fund who are not interested persons of the Fund or the
     Manager, cast in person at a meeting called for the purpose of voting on
     such approval.

     Termination of this Agreement pursuant to this section 10 shall be without
the payment of any penalty.

     11.   This Agreement may be amended at any time by mutual consent of the
parties, provided that such consent on the part of the Fund shall have been
approved by vote of a majority of the outstanding voting securities of the
Series and by vote of a majority of the trustees of the Fund who are not
interested persons of the Fund or the Manager, cast in person at a meeting
called for the purpose of voting on such approval.

     12.   For the purpose of this Agreement, the terms "vote of a majority of
the outstanding voting securities," "interested person," "affiliated person" and
"assignment" 

                                      -5-
<PAGE>
 
shall have their respective meanings defined in the 1940 Act, subject, however,
to such exemptions as may be granted by the Securities and Exchange Commission
under the 1940 Act. References in this Agreement to any assets, property or
liabilities "belonging to" the Series shall have the meaning defined in the
Fund's agreement and declaration of trust as amended from time to time.

     13.   In the absence of willful misfeasance, bad faith or gross negligence
on the part of the Manager, or reckless disregard of its obligations and duties
hereunder, the Manager shall not be subject to any liability to the Fund, to any
shareholder of the Fund or to any other person, firm or organization, for any
act or omission in the course of, or connected with, rendering services
hereunder.

     IN WITNESS WHEREOF, the parties hereto have executed this Agreement on the
day and year first above written.

             (f)  charges and expenses of independent accountants retained by
     the Fund;

             (g)  charges and expenses of any transfer agents and registrars
     appointed by the Fund;

             (h)  brokers' commissions and issue and transfer taxes chargeable
     to the Fund in connection with securities transactions to which the Fund is
     a party;

             (i)  taxes and fees payable by the Fund to federal, state or other
     governmental agencies;

             (j)  any cost of certificates representing shares of the Fund;

                                      -3-
<PAGE>
 
             (k)  legal fees and expenses in connection with the affairs of the
     Fund including registering and qualifying its shares with federal and state
     regulatory authorities;

             (l)  expenses of meetings of shareholders and trustees of the Fund;
and

             (m)  interest, including interest on borrowings by the Fund.

     5.      All activities undertaken by the Manager or any Sub-Adviser or
Administrator pursuant to this Agreement shall at all times be subject to the
supervision and control of the Board of Trustees of the Fund, any duly
constituted committee thereof or any officer of the Fund acting pursuant to like
authority.

     6.      The services to be provided by the Manager and any Sub-Adviser or
Administrator hereunder are not to be deemed exclusive and the Manager and any
Sub-Adviser or Administrator shall be free to render similar services to others,
so long as its services hereunder are not impaired thereby.

     7.      As full compensation for all services rendered, facilities
furnished and expenses borne by the Manager hereunder, the Fund shall pay the
Manager compensation at the annual rate of 0.75% of the Series' average daily
net assets. Such compensation shall be payable monthly in arrears or at such
other intervals, not less frequently than quarterly, as the Board of Trustees of
the Fund may from time to time determine and specify in writing to the Manager.
The Manager hereby acknowledges that the Fund's obligation to pay such
compensation is binding only on the assets and property belonging to the Series.

     8.      If the total of all ordinary business expenses of the Fund as a
whole (including investment advisory fees but excluding taxes and portfolio
brokerage commissions) for any fiscal year exceeds the lowest applicable
percentage of average net assets or income limitations prescribed by any state
in which shares of the Series are qualified for sale, the Manager shall pay such
excess. Solely for purposes of applying such limitations in accordance with the
foregoing sentence, the Series and the Fund shall each be deemed to be a
separate fund subject to such limitations. Should the applicable state
limitation provisions fail to specify how the average net assets of the Fund or
belonging to the Series are to be calculated, that figure shall be calculated by
reference to the average daily net assets of the Fund or the Series, as the case
may be.

     9.      It is understood that any of the shareholders, trustees, officers,
employees and agents of the Fund may be a shareholder, director, officer,
employee or agent of, or be otherwise interested in, the Manager, any affiliated
person of the Manager, any organization in which the Manager may have an
interest or any organization which may have an interest in the Manager; that the
Manager, any such affiliated person or any such organization may have an
interest in the Fund; and that the existence of any such dual interest shall not
affect the validity hereof or of any transactions hereunder except as 

                                      -4-
<PAGE>
 
otherwise provided in the agreement and declaration of trust of the Fund, the
articles of organization of the Manager or specific provisions of applicable
law.

     10.     This Agreement shall become effective as of the date of its
execution, and

             (a)  unless otherwise terminated, this Agreement shall continue in
     effect for two years from the date of execution, and from year to year
     thereafter so long as such continuance is specifically approved at least
     annually (i) by the Board of Trustees of the Fund or by vote of a majority
     of the outstanding voting securities of the Series, and (ii) by vote of a
     majority of the trustees of the Fund who are not interested persons of the
     Fund or the Manager, cast in person at a meeting called for the purpose of
     voting on, such approval;

             (b)  this Agreement may at any time be terminated on sixty days'
     written notice to the Manager either by vote of the Board of Trustees of
     the Fund or by vote of a majority of the outstanding voting securities of
     the Series;

             (c)  this Agreement shall automatically terminate in the event of
     its assignment;

             (d)  this Agreement may be terminated by the Manager on ninety
     days' written notice to the Fund;

             (e)  if New England Securities Corporation, the Fund's principal
     underwriter, requires the Fund or the Series to change its name so as to
     eliminate all references to the words "New England" pursuant to the
     provisions of the Fund's Distribution Agreement relating to the Series with
     said principal underwriter, this Agreement shall automatically terminate at
     the time of such change unless the continuance of this Agreement after such
     change shall have been specifically approved by vote of a majority of the
     outstanding voting securities of the Series and by vote of a majority of
     the trustees of the Fund who are not interested persons of the Fund or the
     Manager, cast in person at a meeting called for the purpose of voting on
     such approval.

     Termination of this Agreement pursuant to this section 10 shall be without
the payment of any penalty.

     11.     This Agreement may be amended at any time by mutual consent of the
parties, provided that such consent on the part of the Fund shall have been
approved by vote of a majority of the outstanding voting securities of the
Series and by vote of a majority of the trustees of the Fund who are not
interested persons of the Fund or the Manager, cast in person at a meeting
called for the purpose of voting on such approval.

     12.     For the purpose of this Agreement, the terms "vote of a majority of
the outstanding voting securities," "interested person," "affiliated person" and
"assignment" 

                                      -5-

to such exemptions as may be granted by the Securities and Exchange Commission
under the 1940 Act. References in this Agreement to any assets, property or
liabilities "belonging to" the Series shall have the meaning defined in the
Fund's agreement and declaration of trust as amended from time to time.

     13.     In the absence of willful misfeasance, bad faith or gross
negligence on the part of the Manager, or reckless disregard of its obligations
and duties hereunder, the Manager shall not be subject to any liability to the
Fund, to any shareholder of the Fund or to any other person, firm or
organization, for any act or omission in the course of, or connected with,
rendering services hereunder.

     IN WITNESS WHEREOF, the parties hereto have executed this Agreement on the

                             SUB-ADVISORY AGREEMENT

                              MFS INVESTORS SERIES


     This Sub-Advisory Agreement (this "Agreement") is entered into as of 
April 28, 1999 by and between New England Investment Management, Inc., a
Massachusetts corporation (the "Manager"), Massachusetts Financial Services
Company, a Delaware corporation (the "Sub-Adviser").

     WHEREAS, the Manager has entered into an Advisory Agreement dated as of
April 28, 1999 (the "Advisory Agreement") with New England Zenith Fund (the
"Trust"), pursuant to which the Manager provides portfolio management and
administrative services to the MFS Investors Series (the "Series");

     WHEREAS, the Advisory Agreement provides that the Manager may delegate any
or all of its portfolio management responsibilities under the Advisory Agreement
to one or more sub-advisers;

     WHEREAS, the Manager desires to retain the Sub-Adviser to render portfolio
management services in the manner and on the terms set forth in this Agreement;

     NOW, THEREFORE, in consideration of the mutual covenants and agreements set
forth in this Agreement, the Manager and the Sub-Adviser agree as follows:

1.   Sub-Advisory Services.
     --------------------- 

          a.   The Sub-Adviser shall, subject to the supervision of the Manager
and in cooperation with any administrator appointed by the Manager (the
"Administrator"), manage the investment and reinvestment of the assets of the
Series. Subject to paragraph 1.g. below, the Sub-Adviser shall manage the Series
in conformity with (1) the investment objective, policies and restrictions of
the Series set forth in the Trust's prospectus and statement of additional
information, as revised or supplemented from time to time, relating to the
Series (the "Prospectus"), (2) any additional policies or guidelines established
by the Manager or by the Trust's trustees that have been furnished in writing to
the Sub-Adviser and (3) the provisions of the Internal Revenue Code (the "Code")
applicable to "regulated investment companies" (as defined in Section 851 of the
Code) and "segregated asset accounts" (as defined in Section 817 of the Code),
all as from time to time in effect (collectively, the "Policies"), and with all
applicable provisions of law, including without limitation all 
<PAGE>
 
applicable provisions of the Investment Company Act of 1940, as amended (the
"1940 Act") and the rules and regulations thereunder. Subject to the foregoing,
the Sub-Adviser is authorized, in its discretion and without prior consultation
with the Manager, to buy, sell, lend and otherwise trade in any stocks, bonds
and other securities and investment instruments on behalf of the Series, without
regard to the length of time the securities have been held and the resulting
rate of portfolio turnover or any tax considerations; and the majority or the
whole of the Series may be invested in such proportions of stocks, bonds, other
securities or investment instruments, or cash, as the Sub-Adviser shall
determine. Notwithstanding the foregoing provisions of this Section 1.a,
however, the Sub-Adviser shall, upon written instructions from the Manager,
effect such portfolio transactions for the Series as the Manager shall determine
are necessary in order for the Series to comply with the Policies.

          b.   The Sub-Adviser shall furnish the Manager and the Administrator
daily, weekly, monthly, quarterly and/or annual reports concerning transactions
and performance of the Series in such form as may be mutually agreed upon, and
agrees to review the Series and discuss the management of the Series with
representatives or agents of the Manager, the Administrator or the Trust at
their reasonable request.  The Sub-Adviser shall permit all books and records
with respect to the Series to be inspected and audited by the Manager and the
Administrator at all reasonable times during normal business hours, upon
reasonable notice.  The Sub-Adviser shall also provide the Manager, the
Administrator or the Trust with such other information and reports as may
reasonably be requested by the Manager, the Administrator or the Trust from time
to time, including without limitation all material as reasonably may be
requested to the Trustees of the Trust pursuant to Section 15(c) of the 1940
Act.

          c.   The Sub-Adviser shall provide to the Manager a copy of the Sub-
Adviser's Form ADV as filed with the Securities and Exchange Commission and as
amended from time to time and a list of the persons whom the Sub-Adviser wishes
to have authorized to give written and/or oral instructions to custodians of
assets of the Series.

          d.   The Sub-Adviser will consult with and assist the Series' pricing
agent regarding the valuation of securities that are not registered for public
sale, not traded on any securities markets, or otherwise may be deemed illiquid
for purposes of the 1940 Act and for which market quotations are not readily
available.

          e.   Unless the Manager gives the Sub-Adviser written instructions to
the contrary, the Sub-Adviser shall use its good faith judgment in a manner
which it reasonably believes best serves the interest of the Series'
shareholders to vote or abstain from voting all proxies solicited by or with
respect to the issuers of securities in which assets of the Series are invested.

                                      -2-
<PAGE>
 
          f.   The Manager shall provide the Sub-Adviser with a list of entities
with which the Sub-Adviser is restricted from engaging in transactions on behalf
of the Series.  The Sub-Adviser shall be responsible for complying with this
restricted list and any changes thereto 10 business days after its receipt.

          g.   The Manager acknowledges that the Sub-Adviser is not the
compliance agent for the Series and does not have access to all of the Series'
books and records necessary to perform certain compliance testing.  However, the
Sub-Adviser shall perform compliance testing with respect to the Series based
upon information in its possession and upon written instructions, if any,
received from the Manager or the Administrator and shall not be held in breach
of this Agreement so long as it performs in accordance with such information and
instructions.

     2.   Obligations of the Manager.
          -------------------------- 

          a.   The Manager shall provide (or cause the Trust's custodian to
provide) timely information to the Sub-Adviser regarding such matters as the
composition of assets in the Series, cash requirements and cash available for
investment in the Series, and all other information as may be reasonably
necessary for the Sub-Adviser to perform its responsibilities hereunder.

          b.   The Manager has furnished the Sub-Adviser a copy of the
Prospectus and statement of additional information of the Series and agrees
during the continuance of this Agreement to furnish the Sub-Adviser copies of
any revisions or supplements thereto at, or, if practicable, before the time the
revisions or supplements become effective.  The Sub-Adviser shall not be
responsible for managing the Series in accordance with changes reflected in any
such revision or supplement until the Sub-Adviser has received such revision or
supplement.  The Manager agrees to furnish the Sub-Adviser with relevant
sections of minutes of meetings of the Trustees of the Trust applicable to the
Series to the extent they may affect the duties of the Sub-Adviser, and with
copies of any financial statements or reports of the Trust with respect to the
Series which are provided to the Series' shareholders, and any further materials
or information which the Sub-Adviser may reasonably request to enable it to
perform its functions under this Agreement.

     3.   Custodian.  The Manager shall provide the Sub-Adviser with a copy of
          ---------                                                           
the Series's agreement with the custodian designated to hold the assets of the
Series (the "Custodian")  and any modifications thereto (the "Custody
Agreement"), copies of such modifications to be provided to the Sub-Adviser a
reasonable time in advance of the effectiveness of such modifications.  The
assets of the Series shall be maintained in the custody of the Custodian
identified in, and in accordance with the terms and conditions of, the Custody
Agreement (or any sub-custodian properly appointed as provided in the Custody
Agreement).  The Sub-Adviser shall provide timely instructions directly to the
Trust's custodian, in the manner and form as required by the Trust's custodian
agreement (including with respect to exchange offerings and 

                                      -3-
<PAGE>
 
other corporate actions) necessary to effect the investment and reinvestment of
the Series' assets. The Sub-Adviser shall have no liability for the acts or
omissions of the Custodian, unless such act or omission is required by and taken
in reliance upon instruction given to the Custodian by a representative of the
Sub-Adviser properly authorized to give such instruction under the Custody
Agreement. Any assets added to the Series shall be delivered directly to the
Custodian.

     4.   Proprietary Rights.  The Manager agrees and acknowledges that the Sub-
          ------------------                                                   
Adviser is the sole owner of the name and mark "MFS". Without the prior review
and approval of the Sub-Adviser, the Manager shall not, and the Manager shall
use its best efforts to cause the Trust not to, make representations regarding
the Sub-Adviser in any disclosure document, advertisement or sales literature or
other materials relating to the Series.  Upon termination of this Agreement for
any reason, the Manager shall cease, and the Manager shall use its best efforts
to cause the Series to cease, all use of the "MFS" mark as soon as reasonably
practicable.

     5.   Expenses.  Except for expenses specifically assumed or agreed to be
          --------                                                           
paid by the Sub-Adviser pursuant hereto, the Sub-Adviser shall not be liable for
any expenses of the Manager or the Trust including, without limitation, (a)
interest and taxes, (b) brokerage commissions and other costs in connection with
the purchase or sale of securities or other investment instruments with respect
to the Series, and (c) custodian fees and expenses.  The Sub-Adviser will pay
its own expenses incurred in furnishing the services to be provided by it
pursuant to this Agreement.

     6.   Purchase and Sale of Assets.  Absent instructions from the Manager to
          ---------------------------                                          
the contrary, the Sub-Adviser shall place all orders for the purchase and sale
of securities for the Series with brokers or dealers selected by the Sub-
Adviser, which may include brokers or dealers affiliated with the Sub-Adviser,
provided such orders comply with Rule 17e-1 (or any successor regulations) under
the 1940 Act in all respects.  To the extent consistent with applicable law,
purchase or sell orders for the Series may be aggregated with contemporaneous
purchase or sell orders of other clients of the Sub-Adviser.  The Sub-Adviser
shall use its best efforts to obtain execution of transactions for the Series at
prices which are advantageous to the Series and at commission rates that are
reasonable in relation to the benefits received.

     7.   Compensation of the Sub-Adviser.  As full compensation for all
          -------------------------------                               
services rendered, facilities furnished and expenses borne by the Sub-Adviser
hereunder, the Manager shall pay the Sub-Adviser compensation at the annual rate
of 0.400% of the first $150 million of the average daily net assets of the
Series, 0.375% of the next $150 million of such assets and 0.350% of such assets
in excess of $300 million.  Such compensation shall be payable monthly in
arrears or at such other intervals, not less frequently than quarterly, as the
Manager is paid by the Series pursuant to the Advisory Agreement.  If the Sub-
Adviser shall serve for less than the whole of any month, the foregoing
compensation shall be prorated.  The Manager may from time to time waive the
compensation it is entitled to receive from the Trust, 

                                      -4-
<PAGE>
 
however, any such waiver will have no effect on the Manager's obligation to pay
the Sub-Adviser the compensation provided for herein.

     8.   Non-Exclusivity.  The Manager and the Series agree that the services
          ---------------                                                     
of the Sub-Adviser are not to be deemed exclusive and that the Sub-Adviser and
its affiliates are free to act as investment manager and provide other services
to various investment companies and other managed accounts, except as the Sub-
Adviser and the Manager or the Administrator may otherwise agree from time to
time in writing before or after the date hereof.  This Agreement shall not in
any way limit or restrict the Sub-Adviser or any of its directors, officers,
employees or agents from buying, selling or trading any securities or other
investment instruments for its or their own account or for the account of others
for whom it or they may be acting, provided that such activities do not
adversely affect or otherwise impair the performance by the Sub-Adviser of its
duties and obligations under this Agreement.  The Manager and the Series
recognize and agree that the Sub-Adviser may provide advice to or take action
with respect to other clients, which advice or action, including the timing and
nature of such action, may differ from or be identical to advice given or action
taken with respect to the Series.  The Sub-Adviser shall for all purposes hereof
be deemed to be an independent contractor and shall, unless otherwise provided
or authorized, have no authority to act for or represent the Trust or the
Manager in any way or otherwise be deemed an agent of the Trust or the Manager.

     9.   Liability.  Except as may otherwise be provided by the 1940 Act or
          ---------                                                         
other federal securities laws, neither the Sub-Adviser  nor any of its officers,
directors, employees or agents (the "Indemnified Parties") shall be subject to
any liability to the Manager, the Trust, the Series or any shareholder of the
Series for any error of judgment, any mistake of law or any loss arising out of
any investment or other act or omission in the course of, connected with, or
arising out of any service to be rendered under this Agreement, except by reason
of willful misfeasance, bad faith or gross negligence in the performance of the
Sub-Adviser's duties or by reason of reckless disregard by the Sub-Adviser of
its obligations and duties.  The Manager shall hold harmless and indemnify the
Indemnified Parties against any loss, liability, cost, damage or expense
(including reasonable attorneys fees and costs) arising from any claim or demand
by any past or present shareholder of the Series that is not based upon the
obligations of the Sub-Adviser with respect to the Series under this Agreement.
The Manager acknowledges and agrees that the Sub-Adviser makes no representation
or warranty, express or implied, that any level of performance or investment
results will be achieved by the Series or that the Series will perform
comparably with any standard or index, including other clients of the Sub-
Adviser, whether public or private.

     10.  Effective Date and Termination.  This Agreement shall become effective
          ------------------------------                                        
as of the date of its execution, and

thereafter so long as such continuance is specifically approved at least
annually (i) by the Board of Trustees of the Trust or by vote of a majority of
the outstanding voting securities of the Series, and (ii) by vote of a majority
of the trustees of the Trust who are not interested persons of the Trust, the
Manager, the Sub-Adviser, cast in person at a meeting called for the purpose of
voting on such approval;

          b.   this Agreement may at any time be terminated on sixty days'
written notice to the Sub-Adviser either by vote of the Board of Trustees of the
Trust or by vote of a majority of the outstanding voting securities of the
Series;

          c.   this Agreement shall automatically terminate in the event of its
assignment or upon the termination of the Advisory Agreement;

          d.   this Agreement may be terminated by the Sub-Adviser on sixty
days' written notice to the Manager and the Trust, or, if approved by the Board
of Trustees of the Trust, by the Manager on sixty days' written notice to the
Sub-Adviser; and

          e.   if the Sub-Adviser requires the Series to change its name so as
to eliminate all references to the word "MFS" then this Agreement shall
automatically terminate at the time of such change unless the continuance of
this Agreement after such change shall have been specifically approved by vote
of a majority of the outstanding voting securities of the Series and by vote of
a majority of the Trustees of the Trust who are not interested persons of the
Trust or the Sub-Adviser, cast in person at a meeting called for the purpose of
voting on such approval.

the payment of any penalty.

such amendment shall also have been approved by vote of a majority of the
outstanding voting securities of the Series and by vote of a majority of the
trustees of the Trust who are not interested persons of the Trust, the Manager
or the Sub-Adviser, cast in person at a meeting called for the purpose of voting
on such approval.

     12.  Certain Definitions.  For the purpose of this Agreement, the terms
          -------------------

"affiliated person" and "assignment" shall have their respective meanings
defined in the 1940 Act, subject, however, to such exemptions as may be granted
by the Securities and Exchange Commission under the 1940 Act.

                             SUB-ADVISORY AGREEMENT

                          MFS RESEARCH MANAGERS SERIES


     This Sub-Advisory Agreement (this "Agreement") is entered into as of 
April 28, 1999 by and between New England Investment Management, Inc., a
Massachusetts corporation (the "Manager"), Massachusetts Financial Services
Company, a Delaware corporation (the "Sub-Adviser").

     WHEREAS, the Manager has entered into an Advisory Agreement dated as of
April 28, 1999 (the "Advisory Agreement") with New England Zenith Fund (the
"Trust"), pursuant to which the Manager provides portfolio management and
administrative services to the MFS Research Managers Series (the "Series");

     WHEREAS, the Advisory Agreement provides that the Manager may delegate any
or all of its portfolio management responsibilities under the Advisory Agreement
to one or more sub-advisers;

     WHEREAS, the Manager desires to retain the Sub-Adviser to render portfolio
management services in the manner and on the terms set forth in this Agreement;

     NOW, THEREFORE, in consideration of the mutual covenants and agreements set
forth in this Agreement, the Manager and the Sub-Adviser agree as follows:

1.   Sub-Advisory Services.
     --------------------- 

          a.   The Sub-Adviser shall, subject to the supervision of the Manager
and in cooperation with any administrator appointed by the Manager (the
"Administrator"), manage the investment and reinvestment of the assets of the
Series. Subject to paragraph 1.g. below, the Sub-Adviser shall manage the Series
in conformity with (1) the investment objective, policies and restrictions of
the Series set forth in the Trust's prospectus and statement of additional
information, as revised or supplemented from time to time, relating to the
Series (the "Prospectus"), (2) any additional policies or guidelines established
by the Manager or by the Trust's trustees that have been furnished in writing to
the Sub-Adviser and (3) the provisions of the Internal Revenue Code (the "Code")
applicable to "regulated investment companies" (as defined in Section 851 of the
Code) and "segregated asset accounts" (as defined in Section 817 of the Code),
all as from time to time in effect (collectively, the "Policies"), and with all
applicable provisions of law, including without limitation all 
<PAGE>
 
applicable provisions of the Investment Company Act of 1940, as amended (the
"1940 Act") and the rules and regulations thereunder. Subject to the foregoing,
the Sub-Adviser is authorized, in its discretion and without prior consultation
with the Manager, to buy, sell, lend and otherwise trade in any stocks, bonds
and other securities and investment instruments on behalf of the Series, without
regard to the length of time the securities have been held and the resulting
rate of portfolio turnover or any tax considerations; and the majority or the
whole of the Series may be invested in such proportions of stocks, bonds, other
securities or investment instruments, or cash, as the Sub-Adviser shall
determine. Notwithstanding the foregoing provisions of this Section 1.a,
however, the Sub-Adviser shall, upon written instructions from the Manager,
effect such portfolio transactions for the Series as the Manager shall determine
are necessary in order for the Series to comply with the Policies.

          b.   The Sub-Adviser shall furnish the Manager and the Administrator
daily, weekly, monthly, quarterly and/or annual reports concerning transactions
and performance of the Series in such form as may be mutually agreed upon, and
agrees to review the Series and discuss the management of the Series with
representatives or agents of the Manager, the Administrator or the Trust at
their reasonable request.  The Sub-Adviser shall permit all books and records
with respect to the Series to be inspected and audited by the Manager and the
Administrator at all reasonable times during normal business hours, upon
reasonable notice.  The Sub-Adviser shall also provide the Manager, the
Administrator or the Trust with such other information and reports as may
reasonably be requested by the Manager, the Administrator or the Trust from time
to time, including without limitation all material as reasonably may be
requested to the Trustees of the Trust pursuant to Section 15(c) of the 1940
Act.

          c.   The Sub-Adviser shall provide to the Manager a copy of the Sub-
Adviser's Form ADV as filed with the Securities and Exchange Commission and as
amended from time to time and a list of the persons whom the Sub-Adviser wishes
to have authorized to give written and/or oral instructions to custodians of
assets of the Series.

          d.   The Sub-Adviser will consult with and assist the Series' pricing
agent regarding the valuation of securities that are not registered for public
sale, not traded on any securities markets, or otherwise may be deemed illiquid
for purposes of the 1940 Act and for which market quotations are not readily
available.

          e.   Unless the Manager gives the Sub-Adviser written instructions to
the contrary, the Sub-Adviser shall use its good faith judgment in a manner
which it reasonably believes best serves the interest of the Series'
shareholders to vote or abstain from voting all proxies solicited by or with
respect to the issuers of securities in which assets of the Series are invested.

                                      -2-
<PAGE>
 
          f.   The Manager shall provide the Sub-Adviser with a list of entities
with which the Sub-Adviser is restricted from engaging in transactions on behalf
of the Series.  The Sub-Adviser shall be responsible for complying with this
restricted list and any changes thereto 10 business days after its receipt.

          g.   The Manager acknowledges that the Sub-Adviser is not the
compliance agent for the Series and does not have access to all of the Series'
books and records necessary to perform certain compliance testing.  However, the
Sub-Adviser shall perform compliance testing with respect to the Series based
upon information in its possession and upon written instructions, if any,
received from the Manager or the Administrator and shall not be held in breach
of this Agreement so long as it performs in accordance with such information and
instructions.

     2.   Obligations of the Manager.
          -------------------------- 

          a.   The Manager shall provide (or cause the Trust's custodian to
provide) timely information to the Sub-Adviser regarding such matters as the
composition of assets in the Series, cash requirements and cash available for
investment in the Series, and all other information as may be reasonably
necessary for the Sub-Adviser to perform its responsibilities hereunder.

          b.   The Manager has furnished the Sub-Adviser a copy of the
Prospectus and statement of additional information of the Series and agrees
during the continuance of this Agreement to furnish the Sub-Adviser copies of
any revisions or supplements thereto at, or, if practicable, before the time the
revisions or supplements become effective.  The Sub-Adviser shall not be
responsible for managing the Series in accordance with changes reflected in any
such revision or supplement until the Sub-Adviser has received such revision or
supplement.  The Manager agrees to furnish the Sub-Adviser with relevant
sections of minutes of meetings of the Trustees of the Trust applicable to the
Series to the extent they may affect the duties of the Sub-Adviser, and with
copies of any financial statements or reports of the Trust with respect to the
Series which are provided to the Series' shareholders, and any further materials
or information which the Sub-Adviser may reasonably request to enable it to
perform its functions under this Agreement.

     3.   Custodian.  The Manager shall provide the Sub-Adviser with a copy of
          ---------                                                           
the Series's agreement with the custodian designated to hold the assets of the
Series (the "Custodian")  and any modifications thereto (the "Custody
Agreement"), copies of such modifications to be provided to the Sub-Adviser a
reasonable time in advance of the effectiveness of such modifications.  The
assets of the Series shall be maintained in the custody of the Custodian
identified in, and in accordance with the terms and conditions of, the Custody
Agreement (or any sub-custodian properly appointed as provided in the Custody
Agreement).  The Sub-Adviser shall provide timely instructions directly to the
Trust's custodian, in the manner and form as required by the Trust's custodian
agreement (including with respect to exchange offerings and 

                                      -3-
<PAGE>
 
other corporate actions) necessary to effect the investment and reinvestment of
the Series' assets. The Sub-Adviser shall have no liability for the acts or
omissions of the Custodian, unless such act or omission is required by and taken
in reliance upon instruction given to the Custodian by a representative of the
Sub-Adviser properly authorized to give such instruction under the Custody
Agreement. Any assets added to the Series shall be delivered directly to the
Custodian.

     4.   Proprietary Rights.  The Manager agrees and acknowledges that the Sub-
          ------------------                                                   
Adviser is the sole owner of the name and mark "MFS". Without the prior review
and approval of the Sub-Adviser, the Manager shall not, and the Manager shall
use its best efforts to cause the Trust not to, make representations regarding
the Sub-Adviser in any disclosure document, advertisement or sales literature or
other materials relating to the Series.  Upon termination of this Agreement for
any reason, the Manager shall cease, and the Manager shall use its best efforts
to cause the Series to cease, all use of the "MFS" mark as soon as reasonably
practicable.

     5.   Expenses.  Except for expenses specifically assumed or agreed to be
          --------                                                           
paid by the Sub-Adviser pursuant hereto, the Sub-Adviser shall not be liable for
any expenses of the Manager or the Trust including, without limitation, (a)
interest and taxes, (b) brokerage commissions and other costs in connection with
the purchase or sale of securities or other investment instruments with respect
to the Series, and (c) custodian fees and expenses.  The Sub-Adviser will pay
its own expenses incurred in furnishing the services to be provided by it
pursuant to this Agreement.

     6.   Purchase and Sale of Assets.  Absent instructions from the Manager to
          ---------------------------                                          
the contrary, the Sub-Adviser shall place all orders for the purchase and sale
of securities for the Series with brokers or dealers selected by the Sub-
Adviser, which may include brokers or dealers affiliated with the Sub-Adviser,
provided such orders comply with Rule 17e-1 (or any successor regulations) under
the 1940 Act in all respects.  To the extent consistent with applicable law,
purchase or sell orders for the Series may be aggregated with contemporaneous
purchase or sell orders of other clients of the Sub-Adviser.  The Sub-Adviser
shall use its best efforts to obtain execution of transactions for the Series at
prices which are advantageous to the Series and at commission rates that are
reasonable in relation to the benefits received.

     7.   Compensation of the Sub-Adviser.  As full compensation for all
          -------------------------------                               
services rendered, facilities furnished and expenses borne by the Sub-Adviser
hereunder, the Manager shall pay the Sub-Adviser compensation at the annual rate
of 0.400% of the first $150 million of the average daily net assets of the
Series, 0.375% of the next $150 million of such assets and 0.350% of such assets
in excess of $300 million.  Such compensation shall be payable monthly in
arrears or at such other intervals, not less frequently than quarterly, as the
Manager is paid by the Series pursuant to the Advisory Agreement.  If the Sub-
Adviser shall serve for less than the whole of any month, the foregoing
compensation shall be prorated.  The Manager may from time to time waive the
compensation it is entitled to receive from the Trust, 

                                      -4-
<PAGE>
 
however, any such waiver will have no effect on the Manager's obligation to pay
the Sub-Adviser the compensation provided for herein.

     8.   Non-Exclusivity.  The Manager and the Series agree that the services
          ---------------                                                     
of the Sub-Adviser are not to be deemed exclusive and that the Sub-Adviser and
its affiliates are free to act as investment manager and provide other services
to various investment companies and other managed accounts, except as the Sub-
Adviser and the Manager or the Administrator may otherwise agree from time to
time in writing before or after the date hereof.  This Agreement shall not in
any way limit or restrict the Sub-Adviser or any of its directors, officers,
employees or agents from buying, selling or trading any securities or other
investment instruments for its or their own account or for the account of others
for whom it or they may be acting, provided that such activities do not
adversely affect or otherwise impair the performance by the Sub-Adviser of its
duties and obligations under this Agreement.  The Manager and the Series
recognize and agree that the Sub-Adviser may provide advice to or take action
with respect to other clients, which advice or action, including the timing and
nature of such action, may differ from or be identical to advice given or action
taken with respect to the Series.  The Sub-Adviser shall for all purposes hereof
be deemed to be an independent contractor and shall, unless otherwise provided
or authorized, have no authority to act for or represent the Trust or the
Manager in any way or otherwise be deemed an agent of the Trust or the Manager.

     9.   Liability.  Except as may otherwise be provided by the 1940 Act or
          ---------                                                         
other federal securities laws, neither the Sub-Adviser  nor any of its officers,
directors, employees or agents (the "Indemnified Parties") shall be subject to
any liability to the Manager, the Trust, the Series or any shareholder of the
Series for any error of judgment, any mistake of law or any loss arising out of
any investment or other act or omission in the course of, connected with, or
arising out of any service to be rendered under this Agreement, except by reason
of willful misfeasance, bad faith or gross negligence in the performance of the
Sub-Adviser's duties or by reason of reckless disregard by the Sub-Adviser of
its obligations and duties.  The Manager shall hold harmless and indemnify the
Indemnified Parties against any loss, liability, cost, damage or expense
(including reasonable attorneys fees and costs) arising from any claim or demand
by any past or present shareholder of the Series that is not based upon the
obligations of the Sub-Adviser with respect to the Series under this Agreement.
The Manager acknowledges and agrees that the Sub-Adviser makes no representation
or warranty, express or implied, that any level of performance or investment
results will be achieved by the Series or that the Series will perform
comparably with any standard or index, including other clients of the Sub-
Adviser, whether public or private.

     10.  Effective Date and Termination.  This Agreement shall become effective
          ------------------------------

the outstanding voting securities of the Series, and (ii) by vote of a majority
of the trustees of the Trust who are not interested persons of the Trust, the
Manager, the Sub-Adviser, cast in person at a meeting called for the purpose of
voting on such approval;

          b.   this Agreement may at any time be terminated on sixty days'
written notice to the Sub-Adviser either by vote of the Board of Trustees of the
Trust or by vote of a majority of the outstanding voting securities of the
Series;

          c.   this Agreement shall automatically terminate in the event of its
assignment or upon the termination of the Advisory Agreement;

          d.   this Agreement may be terminated by the Sub-Adviser on sixty
days' written notice to the Manager and the Trust, or, if approved by the Board
of Trustees of the Trust, by the Manager on sixty days' written notice to the
Sub-Adviser; and

          e.   if the Sub-Adviser requires the Series to change its name so as
to eliminate all references to the word "MFS" then this Agreement shall
automatically terminate at the time of such change unless the continuance of
this Agreement after such change shall have been specifically approved by vote
of a majority of the outstanding voting securities of the Series and by vote of
a majority of the Trustees of the Trust who are not interested persons of the
Trust or the Sub-Adviser, cast in person at a meeting called for the purpose of
voting on such approval.

consent of the Manager and the Sub-Adviser, provided that, if required by law,
such amendment shall also have been approved by vote of a majority of the
outstanding voting securities of the Series and by vote of a majority of the
trustees of the Trust who are not interested persons of the Trust, the Manager
or the Sub-Adviser, cast in person at a meeting called for the purpose of voting
on such approval.

     12.  Certain Definitions.  For the purpose of this Agreement, the terms
          -------------------

"affiliated person" and "assignment" shall have their respective meanings
defined in the 1940 Act, subject, however, to such exemptions as may be granted
by the Securities and Exchange Commission under the 1940 Act.

                               EXPENSE AGREEMENT

     AGREEMENT dated as of April 30, 1999 by and between New England Zenith
Fund, a Massachusetts business trust (the "Trust"), and New England Investment
Management, Inc., a Massachusetts corporation (the "Adviser").

     WHEREAS, the Adviser is the investment adviser of several series of shares
of beneficial interest (the "Series") of the Trust pursuant to separate advisory
agreements relating to each Series; and

     WHEREAS, the Adviser was recently appointed the investment adviser of two
of these Series, which Series are newly-organized; and
 
     WHEREAS, the Trust and the Adviser desire to enter into the arrangements
described herein relating to the payment of certain expenses of the Trust;

     NOW, THEREFORE, the Trust and the Adviser hereby agree as follows:

     1.   Until further notice from the Adviser to the Trust, the Adviser will
waive such portion of the fees payable to it under the Advisory Agreement
relating to each Series listed in this Section 1, or pay such portion of the
other operating expenses (including amortization of organization expenses and
excluding any brokerage costs, interest, taxes or extraordinary expenses)
("Operating Expenses") incurred in the operation of each Series, as is necessary
to reduce the total Operating Expenses of each Series to the following annual
percentages of the average daily net assets of each Series:


     Series                                                       Percentage
     ------                                                       ----------

 
     Alger Equity Growth Series                                    0.90
     Davis Venture Value Series                                    0.90
     Goldman Sachs Midcap Value Series                             0.90
     Loomis Sayles Balanced Series                                 0.85
     MFS Investors Series                                          0.90
     MFS Research Managers Series                                  0.90
     Morgan Stanley International Magnum Equity Series             1.30
     Salomon Brothers Strategic Bond Opportunities Series          0.85
     Salomon Brothers U.S. Government Series                       0.70
<PAGE>
 
     2.   Each Series agrees to repay to the Adviser the amount of fees waived
and expenses borne by the Adviser with respect to such Series pursuant to
Section 1 of this Agreement, subject to the limitations provided in this Section
2.  Such repayment shall be made monthly, but only if the Operating Expenses of
the Series in question, without regard to such repayment, are at an annual rate
(as a percentage of that Series's average daily net assets) based on that
Series' then-current fiscal year that is less than the percentage rate for such
Series set forth in Section 1.  Furthermore, the amount repaid by a Series in
any month shall be limited so that the sum of (a) the amount of such repayment
and (b) the other Operating Expenses of the Series do not exceed the annual rate
(as a percentage of that Series's average daily net assets) for such Series set
forth in Section 1.

     Amounts of fees waived and expenses borne by the Adviser with respect to a
Series pursuant to Section 1 during any fiscal year of such Series shall not be
repayable if the amounts repayable by such Series pursuant to the immediately
preceding two sentences during the period ending two years (three years in the
case of MFS Investors Series and MFS Research Managers Series) after the end of
such fiscal year are not sufficient to completely repay such amounts of fees
waived and expenses borne.  In no event will any Series be obligated to repay
any fees waived or expenses borne by the Adviser with respect to any other
Series.

     3.   The Adviser may by notice in writing to the Trust terminate its
obligation under Section 1 to waive fees or bear expenses with respect to any
Series in any period following the date specified in such notice (or change the
percentage specified in Section 1 with respect to such Series), but no such
change shall affect the obligation (including the amount of the obligation) of
the Series to repay amounts of fees waived or expenses borne by the Adviser
during periods prior to the date specified in such notice.

     4.   A copy of the Agreement and Declaration of Trust establishing the
Trust is on file with the Secretary of The Commonwealth of Massachusetts, and
notice is hereby given that this Agreement is executed with respect to each
Series listed in Section 1 hereof on behalf of the Trust by officers of the
Trust as officers and not individually and that the obligations arising out of
this Agreement are not binding upon any of the trustees, officers or
shareholders of the Fund individually but are binding only upon the assets and
property of the Fund belonging to the respective Series.

                            NEW ENGLAND ZENITH FUND

                               ADVISORY AGREEMENT
                      (Goldman Sachs Midcap Value Series)

     AGREEMENT made this first day of May, 1998 by and between NEW ENGLAND
ZENITH FUND, a Massachusetts business trust (the "Fund"), with respect to its
Goldman Sachs Midcap Value Series (the "Series"), and TNE ADVISERS, INC., a
Massachusetts corporation (the "Manager").

                                  WITNESSETH:

     WHEREAS, the Fund and the Manager wish to enter into an agreement setting
forth the terms upon which the Manager (or certain other parties acting pursuant
to delegation from the Manager) will perform certain services for the Series;

     NOW THEREFORE, in consideration of the premises and covenants hereinafter
contained, the parties agree as follows:

     1. (a) The Fund hereby employs the Manager to furnish the Fund with
Portfolio Management Services (as defined in Section 2 hereof) and
Administrative Services (as defined in Section 3 hereof), subject to the
authority of the Manager to delegate any or all of its responsibilities
hereunder to other parties as provided in Sections 1(b) and (c) hereof.  The
Manager hereby accepts such employment and agrees, at its own expense, to
furnish such services (either directly or pursuant to delegation to other
parties as permitted by Sections 1(b) and (c) hereof) and to assume the
obligations herein set forth, for the compensation herein provided.  The Manager
shall, unless otherwise expressly provided or authorized, have no authority to
act for or represent the Fund in any way or otherwise be deemed an agent of the
Fund.

        (b) The Manager may delegate any or all of its responsibilities 
hereunder with respect to the provision of Portfolio Management Services (and
assumption of related expenses) to one or more other parties (each such party, a
"Sub-Adviser"), pursuant in each case to a written agreement with such Sub-
Adviser that meets the requirements of Section 15 of the Investment Company Act
of 1940 and the rules thereunder (the "1940 Act") applicable to contracts for
service as investment adviser of a registered investment company (including
without limitation the requirements for approval by the trustees of the Fund and
the shareholders of the Series), subject, however, to such exemptions as may be
granted by the Securities and Exchange Commission. Any Sub-Adviser may (but need
not) be affiliated with the Manager. If different Sub-Advisers are engaged to
provide Portfolio Management Services with respect to different segments of the
portfolio of the Series, the Manager shall determine, in the manner described in
the prospectus of the Series from time to time in effect, what portion of the
assets belonging to the Series shall be managed by each Sub-Adviser.
     

                                      
<PAGE>
 
    
        (c) The Manager may delegate any or all of its responsibilities 
hereunder with respect to the provision of Administrative Services to one or
more other parties (each such party, an "Administrator") selected by the
Manager. Any Administrator may (but need not) be affiliated with the Manager.

     2. As used in this Agreement, "Portfolio Management Services" means
management of the investment and reinvestment of the assets belonging to the
Series, consisting specifically of the following:

        (a) obtaining and evaluating such economic, statistical and financial
data and information and undertaking such additional investment research as
shall be necessary or advisable for the management of the investment and
reinvestment of the assets belonging to the Series in accordance with the
Series' investment objectives and policies;

        (b) taking such steps as are necessary to implement the investment
policies of the Series by purchasing and selling of securities, including the
placing of orders for such purchase and sale; and

        (c) regularly reporting to the Board of Trustees of the Fund with
respect to the implementation of the investment policies of the Series.

     3. As used in this Agreement, "Administrative Services" means the
provision to the Fund, by or at the expense of the Manager, of the following:

        (a) office space in such place or places as may be agreed upon from
time to time by the Fund and the Manager, and all necessary office supplies,
facilities and equipment;

        (b) necessary executive and other personnel for managing the affairs
of the Series, including personnel to perform clerical, bookkeeping, accounting,
stenographic and other office functions (exclusive of those related to and to be
performed under contract for custodial, transfer, dividend and plan agency
services by the entity or entities selected to perform such services;

        (c) compensation, if any, of trustees of the Fund who are directors,
officers or employees of the Adviser, any Sub-Adviser or any Administrator or of
any affiliated person (other than a registered investment company) of the
Manager, any Sub-Adviser or any Administrator;

        (d) all services, other than services of counsel, required in
connection with the preparation of registration statements and prospectuses,
including amendments and revisions thereto, all annual, semiannual and periodic
reports, and notices and proxy
     

                                      -2-
<PAGE>
 
    
solicitation material furnished to shareholders of the Fund or regulatory
authorities, to the extent that any such materials relate to the business of the
Series, to the shareholders thereof or otherwise to the Series, the Series to be
treated for these purposes as a separate legal entity and fund; and

        (e) supervision and oversight of the Portfolio Management Services
provided by each Sub-Adviser, and oversight of all matters relating to
compliance by the Fund with applicable laws and with the Fund's investment
policies, restrictions and guidelines, if the Manager has delegated to one or
more Sub-Advisers any or all of its responsibilities hereunder with respect to
the provision of Portfolio Management Services.

     4. Nothing in section 3 hereof shall require the Manager to bear, or to
reimburse the Fund for:

        (a) any of the costs of printing and mailing the items referred to in
sub-section (d) of such section 3;

        (b) any of the costs of preparing, printing and distributing sales
literature;

        (c) compensation of trustees of the Fund who are not directors,

any affiliated person (other than a registered investment company) of the
Manager, any Sub-Adviser or any Administrator;

        (d) registration, filing and other fees in connection with
requirements or regulatory authorities;

        (e) the charges and expenses of any entity appointed by the Fund for
custodial, paying agent, shareholder servicing and plan agent services;

        (f) charges and expenses of independent accountants retained by the
Fund;

        (g) charges and expenses of any transfer agents and registrars
appointed by the Fund;

        (h) brokers' commissions and issue and transfer taxes chargeable to
the Fund in connection with securities transactions to which the Fund is a
party;

        (i) taxes and fees payable by Fund to federal, state or other
governmental agencies;

        (j) any cost of certificates representing shares of the Fund;
     

                                      -3-
<PAGE>
 
    
        (k) legal fees and expenses in connection with the affairs of the Fund
including registering and qualifying its shares with Federal and State
regulatory authorities;

        (l) expenses of meetings of shareholders and trustees of the Fund; and

        (m) interest, including interest on borrowings by the Fund.

     5. All activities undertaken by the Manager or any Sub-Adviser or
Administrator pursuant to this Agreement shall at all times be subject to the
supervision and control of the Board of Trustees of the Fund, any duly
constituted committee thereof or any officer of the Fund acting pursuant to like
authority.

     6. The services to be provided by the Manager and any Sub-Adviser or
Administrator hereunder are not to be deemed exclusive and the Manager and any
Sub-Adviser or Administrator shall be free to render similar services to others,
so long as its services hereunder are not impaired thereby.

     7. As full compensation for all services rendered, facilities furnished
and expenses borne by the Manager hereunder, the Fund shall pay the Manager
compensation at the annual rate of 0.75% of the Series' average daily net
assets.  Such compensation shall be payable monthly in arrears or at such other
intervals, not less frequently than quarterly, as the Board of Trustees of the
Fund may from time to time determine and  specify in writing to the Manager. The
Manager hereby acknowledges that the Fund's obligation to pay such compensation
is binding only on the assets and property belonging to the Series.

     8. If the total of all ordinary business expenses of the Fund as a whole
(including investment advisory fees but excluding taxes and portfolio brokerage
commissions) for any fiscal year exceeds the lowest applicable percentage of
average net assets or income limitations prescribed by any state in which shares
of the Series are qualified for sale, the Manager shall pay such excess. Solely
for purposes of applying such limitations in accordance with the foregoing
sentence, the Series and the Fund shall each be deemed to be a separate fund
subject to such limitations.  Should the applicable state limitation provisions
fail to specify how the average net assets of the Fund or belonging to the
Series are to be calculated, that figure shall be calculated by reference to the
average daily net assets of the Fund or the Series, as the case may be.

     9. It is understood that any of the shareholders, trustees, officers,
employees and agents of the Fund may be a shareholder, director, officer,
employee or agent of, or be otherwise interested in, the Manager, any affiliated
person of the Manager, any organization in which the Manager may have an
interest or any organization which may have an interest in the Manager; that the
Manager, any such affiliated person or any such organization may have an
interest in the Fund; and that the existence of any such dual interest shall not
affect the validity
     

                                      -4-
<PAGE>
 
    
hereof or of any transactions hereunder except as otherwise provided in the
agreement and declaration of trust of the Fund, the articles of organization of
the Manager or specific provisions of applicable law.

     10. This Agreement shall become effective as of the date of its execution,
and

        (a) unless otherwise terminated, this Agreement shall continue in effect
for two years from the date of execution, and from year to year thereafter so
long as such continuance is specifically approved at least annually (i) by the
Board of Trustees of the Fund or by vote of a majority of the outstanding voting
securities of the Series, and (ii) by vote of a majority of the trustees of the
Fund who are not interested persons of the Fund or the Manager, cast in person
at a meeting called for the purpose of voting on, such approval;

        (b) this Agreement may at any time be terminated on sixty days' written
notice to the Manager either by vote of the Board of Trustees of the Fund or by
vote of a majority of the outstanding voting securities of the Series;

        (c) this Agreement shall automatically terminate in the event of its
assignment;

        (d) this Agreement may be terminated by the Manager on ninety days'
written notice to the Fund;

        (e) if New England Securities Corporation, the Fund's principal
underwriter, requires the Fund or the Series to change its name so as to
eliminate all references to the words "New England" or the letters "TNE"
pursuant to the provisions of the Fund's Distribution Agreement relating to the
Series with said principal underwriter, this Agreement shall automatically
terminate at the time of such change unless the continuance of this Agreement
after such change shall have been specifically approved by vote of a majority of
the outstanding voting securities of the Series and by vote of a majority of the
trustees of the Fund who are not interested persons of the Fund or the Manager,
cast in person at a meeting called for the purpose of voting on such approval.

     Termination of this Agreement pursuant to this section 10 shall be without
the payment of any penalty.

     11. This Agreement may be amended at any time by mutual consent of the
parties, provided that such consent on the part of the Fund shall have been
approved by vote of a majority of the outstanding voting securities of the
Series and by vote of a majority of the trustees of the Fund who are not
interested persons of the Fund or the Manager, cast in person at a meeting
called for the purpose of voting on such approval.
     

                                      -5-
<PAGE>
 
    
     12. For the purpose of this Agreement, the terms "vote of a majority of
the outstanding voting securities," "interested person," "affiliated person" and
"assignment" shall have their respective meanings defined in the 1940 Act,
subject, however, to such exemptions as may be granted by the Securities and
Exchange Commission under the 1940 Act. References in this Agreement to any
assets, property or liabilities "belonging to" the Series shall have the meaning
defined in the Fund's agreement and declaration of trust as amended from time to
time.

     13. In the absence of willful misfeasance, bad faith or gross negligence
on the part of the Manager, or reckless disregard of its obligations and duties
hereunder, the Manager shall not be subject to any liability to the Fund, to any
shareholder of the Fund or to any other person, firm or organization, for any
act or omission in the course of, or connected with, rendering services
hereunder.

     IN WITNESS WHEREOF, the parties hereto have executed this Agreement on the
day and year first above written.
