Overview

- --------------------------------------------------------------------------------
FUND INFORMATION KEY
Concise fund-by-fund descriptions begin on page 6. Each description provides
the following information:

Goal and Strategy The fund's particular investment goals and the principal
strategies it intends to use in pursuing those goals.

Subadviser/Manager The firm and individual(s) providing investment management
services to the fund.

Past Performance The fund's total return, measured year-by-year and over time.

Main Risks The significant risk factors associated with the fund. The risks are
categorized as "Primary" or "Secondary". The Primary Risks are considered major
factors in the fund's performance and are described first. The Secondary Risks
are not considered major factors in the fund's performance because the fund
would not normally commit a large portion of its assets to the investments
involved. However, the Secondary Risks are of such a nature that they could
significantly affect the fund's performance, even if the investments are held
in relatively small amounts.

Financial Highlights The fund's operating performance per share, measured year-
by-year.

THE FUNDS
The Trust offers investment choices, or funds, for the variable annuity and
variable life insurance contracts ("variable contracts") of:

 . John Hancock Life Insurance Company ("John Hancock"),

 . John Hancock Variable Life Insurance Company ("JHVLICO"), and

 . Investors Partner Life Insurance Company and its subsidiaries ("IPL").

In some variable contract forms, the Trust is referred to as the "Fund" or "Se-
ries Fund" and the investment choices are referred to as "Portfolios."

RISKS OF FUNDS
These funds, like all mutual funds, are not bank deposits. They are not insured
or guaranteed by the FDIC or any other government agency. You could lose money
by investing in these funds. So, be sure to read all risk disclosure carefully
before investing.

MANAGEMENT

chusetts stock life insurance company. On February 1, 2000, John Hancock
changed its form of organization and its name. Prior to that date, it was John
Hancock Mutual Life Insurance Company, a mutual life insurance company that was
chartered in 1862. At the end of 1999, John Hancock managed approximately $127
billion, of which it owned over $71 billion. Most of the funds have
subadvisers.

Your Investment Choices

- -------------------------------------------------------------------------------
The Trust offers a number of investment choices, or funds, to suit a variety
of objectives under variable contracts. There are 18 funds available under
your variable contract. Each fund has its own strategy and its own risk/reward
profile.The funds can be broadly categorized as equity funds, balanced funds,
bond funds, and international/global funds. Within these broad categories, the
funds can be further categorized as follows:

Equity Funds
Equity funds can be categorized in two ways--by capitalization and by invest-
ment style.

Capitalization             Equity funds can be categorized by market capital-
                           ization, which is defined as the market value of
                           all shares of a company's stock. The following def-
                           initions for large, mid and small cap are based
                           upon statistics at year-end 1999, but are adjusted
                           periodically with broad equity market movements as
                           represented by the Russell 3000(R) Index or other
                           widely-recognized source of market capitalization
                           data. Adjustments are typically made on a quarterly
                           basis, but in extraordinary circumstances may be
                           made as frequently as monthly.

                           Large Cap Funds:
 . Equity Index Fund
                           These funds invest in large, well-established com-
 . Large Cap Value Fund     panies that typically are very actively traded and
                           provide more stable investment returns over time.
 . Large Cap Growth Fund    Large cap companies represent the 300 largest
                           stocks in the Russell 3000(R) Index. Each of those
                           companies has a market capitalization greater than
                           $7.9 billion as of the end of 1999. Large cap funds
                           are appropriate for investors who want the least
                           volatile investment returns within the overall
                           equity markets.

                           Mid Cap Funds:
 . Mid Cap Value Fund
                           These funds invest in medium-sized, less estab-
 . Mid Cap Growth Fund      lished companies that are less actively traded and
                           provide more share price volatility over time than
 . Small/Mid Cap CORE Fund  large cap stocks. Mid cap companies represent the
                           250th to 1000th largest stocks in the Russell
 .Real Estate Equity Fund   3000(R) Index. Each of those companies has a market
                           capitalization between $1.4 billion and $9.7 bil-
                           lion as of the end of 1999. Mid cap funds are
                           appropriate for investors who are willing to accept
                           more volatile investment returns within the overall
                           equity markets with the potential reward of higher
                           long-term returns.

                           Small Cap Funds:
 . Small Cap Value Fund     These funds invest in small newly established com-
                           panies that are less actively traded and have a
                           high level of share price volatility over time.
                           Small cap companies represent the 2000 smallest
                           stocks in the Russell 3000(R) Index. Each of those
                           companies has a market capitalization of less than
                           $1.4 billion as of the end of 1999. Small cap funds
                           are appropriate for investors who are willing to
                           accept the most volatile investment returns within
                           the overall equity markets for the potential reward
                           of higher long-term returns.

Investment Style

                           Value Funds:
 . Large Cap Value Fund
                           Value funds invest in companies that are attrac-
 . Mid Cap Value Fund       tively priced, considering their asset and earnings
                           history. These stocks typically pay above average
 . Small Cap Value Fund     dividends and have low stock prices relative to
                           measures of earnings and book value. Value funds
 . Real Estate Equity Fund  are appropriate for investors who want some divi-
                           dend income and the potential for capital gains,
                           but are less tolerant of share-price fluctuations.


                                                                              3
<PAGE>

                          Growth Funds:
 . Large Cap Growth Fund

                          Growth funds invest in companies believed to have
 . Mid Cap Growth Fund     above-average prospects for capital growth due to
                          their strong earnings and revenue potential. Growth
                          stocks typically have high stock prices relative to
                          measures of earnings and book value. Growth funds
                          are appropriate for investors who are willing to
                          accept more share-price volatility for the potential
                          reward of higher long-term returns.


                          Blend Funds:
 . Equity Index Fund

                          Blend funds invest in both value and growth compa-
 . Small/Mid Cap CORE      nies. Blend funds are appropriate for investors who
  Fund                    seek both dividend and capital appreciation charac-
                          teristics.

Balanced Funds

 . Managed Fund

                          Balanced funds invest in a combination of stocks and
 . Global Balanced         bonds and actively manage the mix of stock and bonds
  Fund                    within a target range. Domestic balanced funds
                          invest in U.S. stocks and bonds. Global balanced
                          funds invest in foreign and U.S. stocks and bonds.

Bond Funds
Bond funds can be categorized in two ways--by average maturity and by credit
quality:

Average Maturity          Bond maturity is a key measure of interest rate
                          risk. A bond's maturity measures the time remaining
                          until the bond matures, or until the repayment of
                          the bond's principal comes due. The longer a bond's
                          maturity, the more sensitive the bond's price is to
                          changes in interest rates.

                          Short:
 . Short Term Bond         These funds invest primarily in bonds with short
  Fund                    maturities, typically less than four years. These
                          funds have less interest rate risk than intermedi-
                          ate-term bond funds.

                          Intermediate:
 . Bond Index Fund

                          These funds invest in bonds of all maturities and
 . Global Bond Fund        maintain an average maturity which is typically
                          between four and ten years. These funds have more
                          interest rate risk than short-term bond funds.

 . High Yield Bond
  Fund

Credit Quality            Credit quality is a measure of the ability of a bond
                          issuer to meet its financial obligations and repay
                          principal and interest. High quality bonds have less
                          credit risk than lower quality bonds. Investment
                          grade bonds typically have "high" or "medium" credit
                          quality ratings (as defined below), while high-yield
                          bonds have "low" credit quality ratings.

                          High:
 . Bond Index Fund

                          These funds focus on the highest-rated, most credit-
 . Global Bond Fund        worthy bonds and typically maintain an average
                          credit quality rating of AAA/Aaa or AA/Aa.

<PAGE>

                           Medium:
 . Short Term Bond          These funds invest in bonds of all credit quality
  Fund                     levels with a focus on high-rated investment grade
                           bonds. These funds typically maintain an average
                           credit quality rating of A or BBB/Baa.

                           Low:
 . High Yield Bond          These funds invest primarily in lower rated bonds--
 Fund                      known as high yield or "junk" bonds. These funds
                           typically maintain a below investment-grade average
                           credit quality rating of BB/Ba or B.

International/Global Equity Funds
International funds invest primarily in securities markets outside the United
States. Global funds invest both in the United States and abroad. These funds
can be categorized by the types of markets they invest in.

                           Developed Markets:
 . Global Equity Fund       These funds invest primarily in the larger, well-
                           established developed or industralized markets
 . International            around the world. These funds have less foreign
  Equity Index Fund        securities risk than emerging market funds.

 . International
  Opportunities Fund
                           Emerging Markets:
 . Emerging Markets         These funds invest primarily in developing or
  Equity Fund              emerging markets and have more foreign securities
                           risk than funds that invest primarily in well-
                           established, developed markets.

In the following pages, any fund investment strategy that is stated as a per-
centage of a fund's assets applies at all times, not just at the time the fund
buys or sells an investment security. The trustees of the Trust can change the
investment goals and strategy of any fund without shareholder (i.e.,
contractowner) approval.

The financial highlights tables on the following pages detail the historical
performance of each fund, including total return information showing the
increase or decrease of an investment in the fund each year (assuming rein-
vestment of all dividends and distributions). The "total investment return"
shown for each fund does not reflect the expenses and charges of the applica-
ble separate accounts and variable contracts. Those expenses and charges vary
considerably from contract to contract and are described in the variable con-
tract prospectus to which this prospectus is attached. If the earliest period
shown in the financial highlights table is less than a full calendar year, the
two "Ratios" shown for that period have been annualized (i.e., projected as if
the fund had been in effect for a full year). However, the "total investment
return" and "turnover rate" for that period have not been annualized.

In this prospectus, the term "stock"' is used as a shorthand reference for
equity investments generally and the term "bond" is used as a shorthand refer-
ence for debt obligations generally.

                                                                              5

Managed Fund

GOAL AND STRATEGY

This is a balanced stock and bond fund that seeks long-term growth in income
and capital.

The Fund invests primarily in a diversified mix of:

 . common stocks of large established U.S. companies;

 . bonds with maturities generally greater than 12 months; and

 . money market and other short-term debt securities with maturities generally
  not greater than 12 months.

The manager makes ongoing decisions about the mix between stocks and bonds. The
manager has a target mix of 60% in equities and 40% in bonds, but actively man-
ages the mix within (+/-) 10 percentage points of the target mix.

The manager selects stocks and bonds using a combination of proprietary
research and quantitative tools. Stocks are purchased that are undervalued rel-
ative to the stock's history and have improving earnings growth prospects.
Bonds are purchased that are attractively priced and have cheap, predictable
cash flows. The Fund is managed using risk control techniques that maintain
risk and industry characteristics similar to the overall market.

The Fund normally invests its equity portion in 80 to 150 stocks, with at least
65% (usually higher) of its equity assets in large cap companies. The Fund may
invest up to 20% of its bond assets in foreign debt securities of developed
countries (denominated in foreign currencies) and up to 15% of its bond assets
in high yield bonds. The Fund normally has 5% or less of its assets in cash and
cash equivalents.

The Fund may purchase other types of securities, for example: American
Depository Receipts (ADRs), and certain derivatives (investments whose value is
based on indices or other securities). The manager actively uses derivatives,
such as futures and forwards, to adjust the Fund's average maturity relative to
the Lehman Brothers Aggregate Bond Index and to implement currency strategies.

In abnormal market conditions, the Fund may take temporary defensive measures--
such as holding unusually large amounts of cash and cash equivalents--that are
inconsistent with the Fund's primary investment strategy. In taking those mea-
sures, the Fund may not achieve its investment goal.

PAST PERFORMANCE

The graph shows how the fund's total return has varied from year to year, while
the table shows performance over time (along with a broad-based market index
for reference). This information may also help provide an indication of the
fund's risks and potential rewards. All figures assume dividend reinvestment.
Past performance does not indicate future results. The performance figures
below do not reflect the deduction of fees and charges payable under the
variable contracts. Such fees and charges would cause the investment returns
under the contracts to be less than that shown below.

MAIN RISKS
Primary


Market Risk: The value of the securities in the Fund may go down in response
to overall stock or bond market movements. Markets tend to move in cycles,
with periods of rising prices and periods of falling prices. Stocks tend to go
up and down in value more than bonds. If the Fund's investments are concen-
trated in certain sectors, the Fund's performance could be worse than the
overall market.


Manager Risk: The manager and its strategy may fail to produce the intended
results. The Fund could underperform its peers or lose money if the manager's
investment strategy does not perform as expected.


Investment Category Risk: The returns of the Fund's specific equity investment
category may lag the returns of the overall stock market. For example, the
Fund's "large cap" approach carries the risk that in certain markets large cap
stocks will underperform mid cap and small cap stocks.


Interest Rate Risk: When interest rates rise, the Fund's bond yields will gen-
erally rise and the Fund's bond prices will generally fall. When interest
rates fall, the reverse will generally occur. The longer the average remaining
maturity of bonds held by the Fund, the more sensitive the Fund is to interest
rate risk. This Fund has more interest rate risk than a short-term bond fund,
but less interest rate risk than a long-term bond fund.


Credit Risk: An issuer of a bond held by the Fund may default on its obliga-
tion to pay interest and repay principal. Also, the credit rating of a bond
held by the fund may be downgraded. In either case, the value of the bond held
by the Trust would fall. All bonds have some credit risk, but in general low-
er-rated bonds have higher credit risk.


Market Allocation Risk: The allocation of the Fund's assets among major asset
classes (i.e., stocks, bonds, and short-term debt securities) may (1) reduce
the Fund's holdings in a class whose value then increases unexpectedly, or (2)
increase the Fund's holdings in a class just prior to its experiencing a loss
of value.


Turnover Risk: In general, the greater the volume of buying and selling by a
fund (i.e., the higher its "turnover rate"), the greater the impact that bro-
kerage commissions and other transaction costs will have on the fund's perfor-
mance. Any turnover rate in excess of 100% is considered relatively high. Nor-
mally, the Fund's turnover rate will be greater than 100%.
Secondary


Foreign Risk: The Fund's foreign securities will pose special risks, due to
limited government regulation, lack of public information, economic, political
and social instability and foreign currency rate fluctuations. Factors such as
lack of liquidity, foreign ownership limits and restrictions on removing cur-
rency also pose special risks.


Derivatives Risk: Certain derivative instruments (such as options, futures and
swaps) can produce disproportionate gains or losses. They are generally con-
sidered more risky than direct equity investments. Also, in a down market,
derivatives could become harder to value or sell at a fair price.


High Yield Bond Risk: Junk bonds, defined as bond securities rated below BBB-
/Baa3, may be subject to more volatile or erratic price movements due to
investor sentiment. In a down market, these high yield securities become
harder to value or to sell at a fair price.


Prepayment/Call Risk: The Fund's share price or yield could be hurt if inter-
est rate movements cause the Fund's mortgage-related and callable securities
to be paid off substantially earlier than expected.

Equity Index Fund

GOAL AND STRATEGY

This is a stock fund that seeks to track the performance of the S&P 500 Index,
which emphasizes the stocks of large U.S. companies.

The manager employs a passive management strategy by normally investing in all
500 stocks included in the Index. The manager invests in each stock in roughly
the same proportion as represented in the Index.

The manager seeks to replicate as closely as possible the aggregate risk char-
acteristics and industry diversification of the Index.

The Fund normally invests in all 500 stocks in the Index, but has no predeter-
mined number of stocks that it must hold. S&P may change the composition of the
Index from time to time. The manager will reflect those changes as soon as
practical.

The Fund is normally fully invested. The manager may invest in stock index
futures to maintain market exposure and manage cash flow.

The Fund may purchase other types of securities, for example: Standard & Poor's
Depository Receipts (SPDRs), American Depository Receipts (ADRs), cash equiva-
lents, and certain derivatives (investments whose value is based on indices or
other securities).

MAIN RISKS

Primary

Index Management Risk:  Certain factors such as the following may cause the
Fund to track the Index less closely:

 . The securities selected by the manager may not be fully representative of
  the Index.

 . Transaction expenses of the Fund may result in the Fund's performance being
  different than that of the Index.

 . The size and timing of the Fund's cash flows may result in the Fund's per-
  formance being different than that of the Index.
Also, index funds like this one will have more difficulty in taking defensive
positions in abnormal market conditions.

Market Risk: The value of the securities in the Fund may go down in response
to overall stock or bond market movements. Markets tend to move in cycles,
with periods of rising prices and periods of falling prices. Stocks tend to go
up and down in value more than bonds. If the Fund's investments are concen-
trated in certain sectors, the Fund's performance could be worse than the
overall market.

Manager Risk: The manager and its strategy may fail to produce the intended
results. The Fund could underperform its peers or lose money if the manager's
investment strategy does not perform as expected.

Investment Category Risk: The returns of the Fund's specific equity investment
category may lag the returns of the overall stock market. For example, the
Fund's "large cap" approach carries the risk that in certain markets large cap
stocks will underperform mid cap and small cap stocks.

Secondary

Derivatives Risk: Certain derivative instruments (such as options, futures and
swaps) can produce disproportionate gains or losses. They are generally con-
sidered more risky than direct equity investments. Also, in a down market,
derivatives could become harder to value or sell at a fair price.

Large Cap Value Fund

GOAL AND STRATEGY

This is a large cap stock fund with a value emphasis that seeks long-term
growth in capital and substantial dividend income.

The Fund invests primarily in a diversified mix of common stocks of large
established U.S. companies that are believed to offer favorable prospects for
increasing dividends and growth in capital.

The manager employs a value approach in selecting stocks using proprietary
equity research. Stocks are purchased that are undervalued by various measures
such as the stock's current price relative to its earnings potential.

The manager looks for companies with:

 . established operating history;

 . above-average dividend yield relative to the S&P 500 Index;

 . low price/earnings ratio relative to the S&P 500 Index;

 . sound balance sheet and other positive financial characteristics; and

 . low stock price relative to the company's underlying value.

The Fund normally invests in 100 to 175 stocks, with at least 65% (usually
higher) of its assets in large cap companies. The Fund normally has 5% or less
of its assets in cash and cash equivalents.

The Fund may purchase other types of securities, for example: American Deposi-
tory Receipts (ADRs), foreign equity securities of developed countries, high
quality intermediate and short-term debt securities, and certain derivatives
(investments whose value is based on indices or other securities).

In abnormal market conditions, the Fund may take temporary defensive measures--
such as holding unusually large amounts of cash and cash equivalents--that are
inconsistent with the Fund's primary investment strategy. In taking those mea-
sures, the Fund may not achieve its investment goal.

MAIN RISKS

Primary

Market Risk: The value of the securities in the Fund may go down in response to
overall stock or bond market movements. Markets tend to move in cycles, with
periods of rising prices and periods of falling prices. Stocks tend to go up
and down in value more than bonds. If the Fund's investments are concentrated
in certain sectors, the Fund's performance could be worse than the overall mar-
ket.

Manager Risk: The manager and its strategy may fail to produce the intended
results. The Fund could underperform its peers or lose money if the manager's
investment strategy does not perform as expected.

Investment Category Risk:  The returns of the Fund's specific equity investment
category may lag the returns of the overall stock market. For example, the
Fund's "value" approach carries the risk that in certain markets "value" stocks
will underperform "growth" stocks. Also, the Fund's "large cap" approach car-
ries the risk that in certain markets large cap stocks will underperform small
cap and mid cap stocks.

Secondary

Foreign Risk: The Fund's foreign securities will pose special risks, due to
limited government regulation, lack of public information, economic, political
and social instability and foreign currency rate fluctuations. Factors such as
lack of liquidity, foreign ownership limits and restrictions on removing cur-
rency also pose special risks.

Derivatives Risk: Certain derivative instruments (such as options, futures and
swaps) can produce disproportionate gains or losses. They are generally consid-
ered more risky than direct equity investments. Also, in a down market, deriva-
tives could become harder to value or sell at a fair price.

Large Cap Growth Fund

GOAL AND STRATEGY

This is a large cap stock fund with a growth emphasis that seeks growth in
capital.

The Fund invests primarily in a diversified mix of common stocks of large
established U.S. companies that are believed to offer above-average potential
for growth in revenues and earnings.

The manager selects stocks using a combination of proprietary equity research
and quantitative tools. Stocks are purchased that are undervalued relative to
the stock's history and have improving earnings growth prospects. The Fund is
managed using risk control techniques that maintain risk and industry charac-
teristics similar to the Russell 1000(R) Growth Index.

The Fund normally invests in 80 to 150 stocks, with at least 65% (usually high-
er) of its assets in large cap companies. The Fund normally has 5% or less of
its assets in cash and cash equivalents.

The Fund may purchase other types of securities, for example: American Deposi-
tory Receipts (ADRs), and certain derivatives (investments whose value is based
on indices or other securities).

In abnormal market conditions, the Fund may take temporary defensive measures--
such as holding unusually large amounts of cash and cash equivalents--that are
inconsistent with the Fund's primary investment strategy. In taking those mea-
sures, the Fund may not achieve its investment goal.

PAST PERFORMANCE

The graph shows how the fund's total return has varied from year to year, while
the table shows performance over time (along with a broad-based market index
for reference). This information may help provide an indication of the fund's
risks and potential rewards. All figures assume dividend reinvestment. Past
performance does not indicate future results. The performance figures below do
not reflect the deduction of fees and charges payable under the variable
contracts. Such fees and charges would cause the investment returns under the
contracts to be less than that shown below.

Mid Cap Value Fund

GOAL AND STRATEGY

This is a mid cap stock fund with a value emphasis that seeks long-term growth
in capital.

The Fund invests primarily in the common stocks of mid-sized U.S. companies
that are believed to sell at a discount to their intrinsic value.

The manager selects stocks using proprietary equity research. Stocks are pur-
chased that are undervalued by various measures such as the stock's current
price relative to its earnings potential.

The manager looks for undervalued companies with:

 . sound balance sheet and other financial characteristics;

 . consistent cash flow;

 . strong position relative to the competition; and

 . high level of stock ownership among management.

The Fund normally invests in 50 to 75 stocks, with at least 65% (usually high-
er) of its assets in mid cap companies. The Fund normally has 5% or less of its
assets in cash and cash equivalents.

The Fund may purchase other types of securities, for example: American Deposi-
tory Receipts (ADRs), and certain derivatives (investments whose value is based
on indices or other securities).

In abnormal market conditions, the Fund may take temporary defensive measures--
such as holding unusually large amounts of cash and cash equivalents--that are
inconsistent with the Fund's primary investment strategy. In taking those mea-
sures, the Fund may not achieve its investment goal.

MAIN RISKS

Primary

Small /Mid Cap Stock Risk: The Fund's investment in smaller or mid-sized compa-
nies may be subject to more erratic price movements than investment in large
established companies.

Market Risk: The value of the securities in the Fund may go down in response to
overall stock or bond market movements. Markets tend to move in cycles, with
periods of rising prices and periods of falling prices. Stocks tend to go up
and down in value more than bonds. If the Fund's investments are concentrated
in certain sectors, the Fund's performance could be worse than the overall mar-
ket.

Manager Risk: The manager and its strategy may fail to produce the intended
results. The Fund could underperform its peers or lose money if the manager's
investment strategy does not perform as expected.

Investment Category Risk: The returns of the Fund's specific equity investment
category may lag the returns of the overall stock market. For example, the
Fund's "value" approach carries the risk that in certain markets "value" stocks
will underperform "growth" stocks. Also, the Fund's "mid cap" approach carries
the risk that in certain markets mid cap stocks will underperform small cap and
large cap stocks.

Concentration Risk: The Fund's investment in securities of a smaller number of
issuers could produce more volatile performance relative to funds that invest
in a larger number of issuers. The more concentrated a fund's holdings are, the
more likely it is a specific security's poor performance will hurt the fund
significantly.

Turnover Risk: In general, the greater the volume of buying and selling by a
fund (i.e., the higher its "turnover rate"), the greater the impact that bro-
kerage commissions and other transaction costs will have on the fund's perfor-
mance. Any turnover rate in excess of 100% is considered relatively high. The
Fund had an unusually high turnover rate in 1999 due to the high volatility of
the market in 1999 and the subadviser's implementation of a more vigilant sell
discipline. Normally, the Fund's turnover rate will be less than 100%.

Secondary

Derivatives Risk: Certain derivative instruments (such as options, futures and
swaps) can produce disproportionate gains or losses. They are generally consid-
ered more risky than direct equity investments. Also, in a down market, deriva-
tives could become harder to value or sell at a fair price.

chased that are expected to have earnings growth potential that may not be rec-
ognized by the investment community. The manager selects stocks without regard
to any pre- defined industry or sector selection criteria.

The manager looks for companies experiencing:

 . above-average growth relative to their peers or the general economy; and

 . positive change due to new product developments, improved regulatory environ-
  ment or a new management team.

The Fund is non-diversified, which means it can take larger positions in a
smaller number of issuers. Based upon its current size and strategy, the Fund
invests in 35 to 75 stocks, with at least 65% of its assets in mid cap compa-
nies. The Fund normally has 15% or less of its assets in cash and cash equiva-
lents.
The Fund may purchase other types of securities, for example: American Deposi-
tory Receipts (ADRs), foreign equity securities of developed countries, and
certain derivatives (investments whose value is based on indices or other
securities).

In abnormal market conditions, the Fund may take temporary defensive measures--
such as holding unusually large amounts of cash and cash equivalents--that are
inconsistent with the Fund's primary investment strategy. In taking those mea-
sures, the Fund may not achieve its investment goal.

PAST PERFORMANCE

The graph shows how the fund's total return has varied from year to year, while
the table shows performance over time (along with a broad-based market index

risks and potential rewards. All figures assume dividend reinvestment. Past
performance does not indicate future results. The performance figures below do
not reflect the deduction of fees and charges payable under the variable
contracts. Such fees and charges would cause the investment returns under the

MAIN RISKS

Primary

Small /Mid Cap Stock Risk: The Fund's investment in smaller or mid-sized compa-
nies may be subject to more erratic price movements than investment in large
established companies.

Non-Diversified Fund Risk: The Fund's larger position in individual issuers and
in a smaller number of issuers could produce more volatile performance relative
to more diversified funds. The less diversified a fund's holdings are, the more
likely it is that a specific security's poor performance will hurt the fund
significantly.

Market Risk: The value of the securities in the Fund may go down in response to
overall stock or bond market movements. Markets tend to move in cycles, with
periods of rising prices and periods of falling prices. Stocks tend to go up
and down in value more than bonds. If the Fund's investments are concentrated
in certain sectors, the Fund's performance could be worse than the overall mar-
ket.

Manager Risk: The manager and its strategy may fail to produce the intended
results. The Fund could underperform its peers or lose money if the manager's
investment strategy does not perform as expected.

Investment Category Risk: The returns of the Fund's specific equity investment
category may lag the returns of the overall stock market. For example, the
Fund's "growth" approach carries the risk that in certain markets "growth"
stocks will underperform "value" stocks. Also, the Fund's "mid cap" approach
carries the risk that in certain markets mid cap stocks will underperform small
cap and large cap stocks.

Concentration Risk: The Fund's investment in securities of a smaller number of
issuers could produce more volatile performance relative to funds that invest
in a larger number of issuers. The more concentrated a fund's holdings are, the
more likely it is a specific security's poor performance will hurt the fund
significantly.

Turnover Risk: In general, the greater the volume of buying and selling by a
fund (i.e., the higher its "turnover rate"), the greater the impact that bro-
kerage commissions and other transaction costs will have on the fund's perfor-
mance. Any turnover rate in excess of 100% is considered relatively high. Nor-
mally, the Fund's turnover rate will be greater than 100%.

Secondary

Foreign Risk: The Fund's foreign securities will pose special risks, due to
limited government regulation, lack of public information, economic, political
and social instability and foreign currency rate fluctuations. Factors such as
lack of liquidity, foreign ownership limits and restrictions on removing cur-
rency also pose special risks.

Derivatives Risk: Certain derivative instruments (such as options, futures and
swaps) can produce disproportionate gains or losses. They are generally consid-
ered more risky than direct equity investments. Also, in a down market, deriva-
tives could be- come harder to value or sell at a fair price.

Real Estate Equity Fund

GOAL AND STRATEGY

This is a real estate stock fund that seeks above-average income and long-term
growth in capital.

The Fund invests primarily in:

 . equity securities of real estate investment trusts (REITs) that own commer-
  cial and multi-family residential real estate; and

 . equity securities of real estate operating companies (i.e., companies with at
  least 75% of revenue, income or fair asset value derived from real estate).

The manager selects real estate stocks using a combination of proprietary,
equity research and quantitative tools. Real estate stocks are purchased that
are undervalued relative to the stock's history and the market and have improv-
ing earnings growth prospects.

The manager looks for real estate stocks with:

 . proven track records,

 . strong management whose interests are aligned with shareholders,

 . attractive real estate holdings, and

 . a flexible financial structure.

The manager employs risk control techniques to maintain risk, style and indus-
try characteristics similar to the public equity real estate market. The Fund
normally invests in 30 to 60 securities. The Fund normally has 5% or less of
its assets in cash and cash equivalents.

The Fund also may purchase other types of securities, for example: American
Depository Receipts (ADRs), convertible securities, and equity securities of
non-real estate businesses whose real estate holdings are significant in rela-
tion to their market capitalization.

In abnormal market conditions, the Fund may take temporary defensive measures--
such as holding unusually large amounts of cash and cash equivalents--that are
inconsistent with the Fund's primary investment strategy. In taking those mea-
sures, the Fund may not achieve its investment goal.

MAIN RISKS

Primary

Real Estate Securities Risk: Real estate investment trusts (REITs) or other
real estate-related equity securities may be affected by changes in the value
of the underlying property owned by the trust. Mortgage REITs may be affected
by the quality of any credit extended. Other potential risks include the possi-
bility of failing to qualify for tax-free pass-through of income under the
Internal Revenue Code or failing to maintain exemption under the Investment
Company Act of 1940.

Market Risk: The value of the securities in the Fund may go down in response to
overall stock or bond market movements. Markets tend to move in cycles, with
periods of rising prices and periods of falling prices. Stocks tend to go up
and down in value more than bonds. If the Fund's investments are concentrated
in certain sectors, the Fund's performance could be worse than the overall mar-
ket.

Manager Risk: The manager and its strategy may fail to produce the intended
results. The Fund could underperform its peers or lose money if the manager's
investment strategy does not perform as expected.

Concentration Risk: The Fund's investment in securities of a smaller number of
issuers could produce more volatile performance relative to funds that invest
in a larger number of issuers. The more concentrated a fund's holdings are, the
more likely it is a specific security's poor performance will hurt the fund
significantly.

Small /Mid Cap Stock Risk: The Fund's investment in smaller or mid-sized compa-
nies may be subject to more erratic price movements than investment in large
established companies.

Small/Mid Cap CORE Fund
GOAL AND STRATEGY

This is a small/mid cap stock fund that seeks long-term growth in capital.

The Fund invests primarily in a diversified mix of the common stocks of small
and mid-sized U.S. companies that are believed to offer:

 . favorable prospects for increasing dividends and capital appreciation (i.e.,
  "value" companies); and

 . above-average potential for growth in revenues and earnings (i.e. "growth"
  companies).

The manager selects stocks using a combination of quantitative techniques and
equity research. The manager employs an investment process known as CORE, "Com-
puter Optimized, Research-Enhanced," that employs a proprietary quantitative
model. Stocks are purchased that have strong expected earnings growth and
momentum and better valuation and risk characteristics than the Russell
2500(TM) Index. The Fund is managed using risk control techniques to maintain
risk, style, capitalization and industry characteristics similar to the Russell
2500(TM) Index.

The Fund normally invests in 200 to 600 stocks, with at least 65% (usually
higher) of the Fund's assets in small cap and mid cap companies. The Fund nor-
mally has 10% or less of its assets in cash and cash equivalents.

The Fund may purchase other types of securities, for example: American Deposi-
tory Receipts (ADRs), Standard & Poor's Depository Receipts (SPDRs), and cer-
tain derivatives (investments whose value is based on indices or other securi-
ties).

In abnormal market conditions, the Fund may take temporary defensive measures--
such as holding unusually large amounts of cash and cash equivalents--that are
inconsistent with the Fund's primary investment strategy. In taking those mea-
sures, the Fund may not achieve its investment goal.

MAIN RISKS

Primary

Small /Mid Cap Stock Risk: The Fund's investment in smaller or mid-sized compa-
nies may be subject to more erratic price movements than investment in large
established companies.

Market Risk: The value of the securities in the Fund may go down in response to
overall stock or bond market movements. Markets tend to move in cycles, with
periods of rising prices and periods of falling prices. Stocks tend to go up

Investment Category Risk: The returns of the Fund's specific equity investment
category may lag the returns of the overall stock market. For example, the
Fund's "small/mid cap" approach carries the risk that in certain markets
small/mid cap stocks will underperform large cap stocks.

Turnover Risk: In general, the greater the volume of buying and selling by a
fund (i.e., the higher its "turnover rate"), the greater the impact that bro-
kerage commissions and other transaction costs will have on the fund's perfor-
mance. Any turnover rate in excess of 100% is considered relatively high. The
Fund had unusually high turnover in 1999 and is expected to experience similar
turnover in 2000. This higher than expected turnover is due to (i) the rela-
tively small size of the Fund, which magnifies the effect of contributions and
redemptions, and (ii) the high volatility of the market, which in 1999 resulted
in the subadviser implementing procedures to reduce the Fund's tracking risk.
Normally, the Fund's turnover rate will be less than 100%.

Secondary

Derivatives Risk: Certain derivative instruments (such as options, futures and
swaps) can produce disproportionate gains or losses. They are generally consid-
ered more risky than direct equity investments. Also, in a down market, deriva-
tives could become harder to value or sell at a fair price.

Small Cap Value Fund

GOAL AND STRATEGY

This is a small cap stock fund with a value emphasis that seeks long-term
growth in capital.

The Fund invests primarily in a diversified mix of the common stocks of small
U.S. companies that are believed to offer favorable prospects for increasing
dividends and capital appreciation.

The manager applies a combination of quantitative techniques and equity
research to identify the best values among small company stocks.

Stocks are evaluated based on multiple factors, including:

 . earnings-to-price ratios;

 . earnings estimate revisions;

 . relative price strength; and

 . share issuance/buyback.

The Fund is managed using risk control techniques to maintain risk, style, cap-
italization and industry characteristics similar to the Russell 2000(R) Value
Index. The Fund normally invests in 150 to 250 stocks, with at least 65% (usu-
ally higher) of its assets in small cap companies. The Fund normally has 5% or
less of its assets in cash and cash equivalents.

The Fund may purchase other types of securities, for example: American Deposi-
tory Receipts (ADRs), and certain derivatives (investments whose value is based
on indices or other securities).

In abnormal market conditions, the Fund may take temporary defensive measures--
such as holding unusually large amounts of cash and cash equivalents--that are
inconsistent with the Fund's primary investment strategy. In taking those mea-
sures, the Fund may not achieve its investment goal.

MAIN RISKS

Primary

Small /Mid Cap Stock Risk: The Fund's investment in smaller or mid-sized compa-
nies may be subject to more erratic price movements than investment in large
established companies.

Market Risk: The value of the securities in the Fund may go down in response to
overall stock or bond market movements. Markets tend to move in cycles, with
periods of rising prices and periods of falling prices. Stocks tend to go up
and down in value more than bonds. If the Fund's investments are concentrated
in certain sectors, the Fund's performance could be worse than the overall mar-
ket.

Manager Risk: The manager and its strategy may fail to produce the intended
results. The Fund could underperform its peers or lose money if the manager's
investment strategy does not perform as expected.

Investment Category Risk: The returns of the Fund's specific equity investment
category may lag the returns of the overall stock market. For example, the
Fund's "value" approach carries the risk that in certain markets "value" stocks
will underperform "growth" stocks. Also, the Fund's "small cap" approach car-
ries the risk that in certain markets small cap stocks will underperform mid
cap and large cap stocks.

Turnover Risk: In general, the greater the volume of buying and selling by a
fund (i.e., the higher its "turnover rate"), the greater the impact that bro-
kerage commissions and other transaction costs will have on the fund's perfor-
mance. Any turnover rate in excess of 100% is considered relatively high. Nor-
mally, the Fund's turnover rate will be greater than 100%.

Secondary

Derivatives Risk: Certain derivative instruments (such as options, futures and
swaps) can produce disproportionate gains or losses. They are generally consid-
ered more risky than direct equity investments. Also, in a down market, deriva-
tives could become harder to value or sell at a fair price.

Global Equity Fund
GOAL AND STRATEGY

This is a global stock fund that seeks long-term growth in capital.

The Fund primarily invests in a diversified mix of common stocks of:

 . large established U.S. companies; and

 . large established foreign companies located in countries throughout the
  world, including developed, newly industrialized, and emerging countries.

The manager makes ongoing decisions about the mix between U.S. and foreign
stocks. The manager has a target mix of 40% in U.S. stocks and 60% in foreign
stocks, but actively manages the mix within (+/-) 20 percentage points of the
target mix.

The manager uses global economic and industry analysis to identify global eco-
nomic and industry themes. The manager looks for companies that will benefit
from:

 . global economic trends;

 . promising technologies or products; and

 . specific country opportunities resulting from changing geopolitical, currency
  or economic relationships.

The manager purchases stocks of companies that are:

 . in growth industries;

 . efficient producers; and

 . undervalued relative to long-term growth potential.

The Fund invests:

 . in at least 3 different countries (including the U.S.), but normally in more
  than 15 countries; and

 . no more than 10% of its assets in emerging markets stocks.

Although the Fund may employ foreign currency hedging techniques, the Fund nor-
mally maintains the currency exposure of the underlying equity investments.

The Fund normally invests in 90 to 120 stocks, with at least 65% (usually high-
er) of its assets in large cap companies. The Fund normally has 5% or less of
its assets in cash and cash equivalents.

The Fund may purchase other types of securities, for example: American Deposi-
tory Receipts (ADRs), Global Depository Receipts (GDRs), European Depository
Receipts (EDRs), and certain derivatives (investments whose value is based on
indices or other securities).

In abnormal market conditions, the Fund may take temporary defensive measures--
such as holding unusually large amounts of cash and cash equivalents or invest-
ing 100% of its assets in U.S. companies--that are inconsistent with the Fund's
primary investment strategy. In taking those measures, the Fund may not achieve
its investment goal.

MAIN RISKS

Primary

Foreign Risk: The Fund's foreign securities will pose special risks, due to
limited government regulation, lack of public information, economic, political
and social instability and foreign currency rate fluctuations. Factors such as
lack of liquidity, foreign ownership limits and restrictions on removing cur-
rency also pose special risks. All foreign securities have some degree of for-
eign risk. However, to the extent the Fund invests in emerging market coun-
tries, it will have a significantly higher degree of foreign risk than if it
invested exclusively in developed or newly-industrialized countries.
Market Risk: The value of the securities in the Fund may go down in response
to overall stock or bond market movements. Markets tend to move in cycles,
with periods of rising prices and periods of falling prices. Stocks tend to go
up and down in value more than bonds. If the Fund's investments are concen-
trated in certain sectors, the Fund's performance could be worse than the
overall market.

Market Allocation Risk: The allocation of the Fund's assets among domestic and
international equity regions may (1) reduce the Fund's holdings in a region
whose value then increases unexpectedly, or (2) increase the Fund's holdings
in a region just prior to its experiencing a loss of value.
Manager Risk: The manager and its strategy may fail to produce the intended
results. The Fund could underperform its peers or lose money if the manager's
investment strategy does not perform as expected.


Secondary

Derivatives Risk: Certain derivative instruments (such as options, futures and
swaps) can produce disproportionate gains or losses. They are generally con-
sidered more risky than direct equity investments. Also, in a down market,
derivatives could become harder to value or sell at a fair price.

Global Balanced Fund
(Formerly International Balanced Fund)

GOAL AND STRATEGY

This is a non-diversified global balanced stock and bond fund that seeks long-
term growth in income and capital.

The Fund invests primarily in a mix of:

 . U.S. and foreign common stocks of large companies within developed markets;
  and

 . U.S. and foreign investment grade bonds of issuers within developed markets
  with maturities generally greater than 12 months.

The manager makes ongoing decisions about the mix between stocks and bonds. The
manager has a target mix of 65% stocks and 35% bonds, but actively manages the
mix within (+/-) 10 percentage points of the target mix.

The Fund invests:

 . in at least 3 different countries, but normally invests in 10 to 20 coun-
  tries; and

 . no more than 10% of its assets in emerging market stocks and bonds.

The manager selects stocks and bonds using fundamental value analysis to iden-
tify fairly priced investments with long-term sustainable cash flows. The man-
ager determines fundamental value by focusing on:

 . current market prices relative to fundamental values;

 . broad-based indices for stocks, bonds, and markets; and

 . economic variables such as productivity, inflation and global competitive-
  ness.

The Fund is non-diversified, which means that it can take larger positions in a
smaller number of issuers. However, the Fund normally invests in 125 to 250
stocks within the stock portion. The Fund normally has 10% or less of its
assets in cash and cash equivalents.

The Fund may purchase other types of securities, for example: American Deposi-
tory Receipts (ADRs), Global Depository Receipts (GDRs), European Depository
Receipts (EDRs), high yield bonds, and certain derivatives (investments whose
value is based on indices or other securities).

The manager actively uses derivatives, such as futures and forwards, to manage
the Fund's average maturity relative to the Salomon Brothers World Government
Bond Index Unhedged and to implement foreign currency strategies. Currency man-
agement strategies are primarily used for hedging purposes and to protect
against anticipated changes in foreign currency exchange rates.

In abnormal market conditions, the Fund may take temporary defensive measures--
such as holding unusually large amounts of cash and cash equivalents--that are
inconsistent with the Fund's primary investment strategy. In taking those mea-
sures, the Fund may not achieve its investment goal.

tries, it will have a significantly higher degree of foreign risk than if it
invested exclusively in developed or newly-industrialized countries.

Non-Diversified Fund Risk: The Fund's larger position in foreign government
securities could produce more volatile performance relative to funds with
smaller positions. The less diversified a fund's holdings are, the more likely
it is that a specific security's poor performance will hurt the fund signifi-
cantly.

Market Risk: The value of the securities in the Fund may go down in response to
overall stock or bond market movements. Markets tend to move in cycles, with
periods of rising prices and periods of falling prices. Stocks tend to go up
and down in value more than bonds. If the Fund's investments are concentrated
in certain sectors, the Fund's performance could be worse than the overall mar-
ket.
Manager Risk: The manager and its strategy may fail to produce the intended
results. The Fund could underperform its peers or lose money if the manager's
investment strategy does not perform as expected.

Investment Category Risk: The returns of the Fund's specific equity investment
category may lag the returns of the overall stock market. For example, the
Fund's "value" approach carries the risk that in certain markets "value" stocks
will underperform "growth" stocks. Also, the Fund's "large/mid cap" approach
carries the risk that large/mid cap stocks will underperform small cap stocks.

Market Allocation Risk: The allocation of the Fund's assets between the major
asset classes (i.e., stocks and bonds) may (1) reduce the Fund's holdings in a
class whose value then increases unexpectedly, or (2) increase the Fund's hold-
ings in a class just prior to its experiencing a loss of value.

Interest Rate Risk: When interest rates rise, the Fund's bond yields will gen-
erally rise and the Fund's bond prices will generally fall. When interest rates
fall, the reverse will generally occur. The longer the average remaining matu-
rity of bonds held by the Fund, the more sensitive the Fund is to interest rate
risk. This Fund has more interest rate risk than a short-term bond fund, but
less interest rate risk than a long-term bond fund.
Credit Risk: An issuer of a bond held by the Fund may default on its obligation
to pay interest and repay principal. Also, the credit rating of a bond held by
the fund may be downgraded. In either case, the value of the bond held by the
Trust would fall. All bonds have some credit risk, but in general lower-rated
bonds have higher credit risk.

Turnover Risk. In general, the greater the volume of buying and selling by a
fund (i.e., the higher its "turnover rate"), the greater the impact that bro-
kerage commissions and other transaction costs will have on the fund's perfor-
mance. Any turnover rate in excess of 100% is considered relatively high. Nor-
mally, the Fund's turnover rate will be greater than 100%.

Secondary

Derivatives Risk: Certain derivative instruments (such as options, futures and
swaps) can produce disproportionate gains or losses. They are generally consid-
ered more risky than direct equity investments. Also, in a down market, deriva-
tives could become harder to value or sell at a fair price.

High Yield Bond Risk. Junk bonds, defined as bond securities rated below BBB-
/Baa3, may be subject to more volatile or erratic price movements due to
investor sentiment. In a down market, these high yield securities become harder
to value or to sell at a fair price.

International Equity Index Fund

GOAL AND STRATEGY

This is an international stock fund that seeks to track the performance of
broad-based equity indices of foreign companies in developed and emerging mar-
kets.

The Fund is managed relative to a target mix of 90% in the MSCI EAFE GDP Index
and 10% in the MSCI EMF Index. The EAFE GDP Index, known as the Europe Austral-
asia and Far East Index, includes foreign companies in developed markets, with
country index weights based upon a country's Gross Domestic Product (GDP). The
EMF Index, known as the Emerging Markets Free Index, includes foreign companies
in emerging markets, with country index weights based upon a country's market
capitalization.

The manager employs a passive management strategy using quantitative techniques
to invest in a representative sample of stocks in the Index. The manager
selects stocks in an attempt to track, as closely as possible, the characteris-
tics of the Index, including country and sector weights. The Fund normally
invests in 400 to 1,200 stocks.

The Index composition changes from time to time. The manager will reflect those
changes as soon as practical.

The Fund is normally fully invested. The manager may invest in stock index
futures to maintain market exposure and manage cash flow. Although the Fund may
employ foreign currency hedging techniques, the Fund normally maintains the
currency exposure of the underlying equity investments.


The Fund may purchase other types of securities, for example: American Deposi-
tory Receipts (ADRs), Global Depository Receipts (GDRs), European Depository
Receipts (EDRs), cash equivalents, and certain derivatives (investments whose
value is based on indices or other securities).

Note: "MSCI EAFE GDP Index" and "MSCI EMF Index" are the exclusive property of
Morgan Stanley & Co., Incorporated and are registered service marks of Morgan
Stanley Capital International.

MAIN RISKS
Primary
Foreign Risk: The Fund's foreign securities will pose special risks, due to
limited government regulation, lack of public information, economic, political
and social instability and foreign currency rate fluctuations. Factors such as
lack of liquidity, foreign ownership limits and restrictions on removing cur-
rency also pose special risks. All foreign securities have some degree of for-
eign risk. However, to the extent the Fund invests in emerging market coun-
tries, it will have a significantly higher degree of foreign risk than if it
invested exclusively in developed or newly-industrialized countries.


Index Management Risk: Certain factors such as the following may cause the
Fund to track the Index less closely:


 . The securities selected by the manager may not be fully representative of
  the Index.

 . Transaction expenses of the Fund may result in the Fund's performance being
  different than that of the Index.
 . The size and timing of the Fund's cash flows may result in the Fund's per-
  formance being different than that of the Index.


Also, index funds like this one will have more difficulty in taking defensive
positions in abnormal market conditions.


Market Risk: The value of the securities in the Fund may go down in response
to overall stock or bond market movements. Markets tend to move in cycles,
with periods of rising prices and periods of falling prices.

Stocks tend to go up and down in value more than bonds. If the Fund's invest-
ments are concentrated in certain sectors, the Fund's performance could be
worse than the overall market.


Manager Risk: The manager and its strategy may fail to produce the intended
results. The Fund could underperform its peers or lose money if the manager's
investment strategy does not perform as expected.


Secondary
Derivatives Risk:  Certain derivative instruments (such as options, futures
and swaps) can produce disproportionate gains or losses. They are generally
considered more risky than direct equity investments. Also, in a down market,
derivatives could become harder to value or sell at a fair price.

International Opportunities Fund

GOAL AND STRATEGY

This is an international stock fund that seeks long-term growth in capital.

The Fund primarily invests in a diversified mix of common stocks of large
established and medium-sized foreign companies located throughout the world,
including developed, newly industrialized, and emerging countries.

The manager determines the distribution among countries and regions by using a
combination of fundamental research and economic analysis, emphasizing:

 . prospects for relative economic growth between foreign countries;

 . expected levels of inflation;

 . government policies influencing business conditions; and

 . outlook for currency relationships.
The manager selects stocks that have growth characteristics such as:

 . leading market position or technological leadership;

 . high return on invested capital;

 . healthy balance sheets with relatively low debt;

 . strong competitive advantage;

 . strength of management; and

 . earnings growth and cash flow sufficient to support growing dividends.

The Fund invests:

 . in at least 3 different countries; and

 . no more than 20% of its assets in emerging market stocks.

Although the Fund may employ foreign currency hedging techniques, the Fund nor-
mally maintains the currency exposure of the underlying equity investments.
The Fund normally invests in 200 to 300 stocks in 15 to 20 countries. The Fund
normally has 10% or less of its assets in cash and cash equivalents.

The Fund also may purchase other types of securities, for example: American
Depository Receipts (ADRs), Global Depository Receipts (GDRs), European Deposi-
tory Receipts (EDRs), and certain derivatives (investments whose value is based
on indices or other securities).

In abnormal market conditions, the Fund may take temporary defensive measures--
such as holding unusually large amounts of cash and cash equivalents--that are
inconsistent with the Fund's primary investment strategy. In taking those mea-
sures, the Fund may not achieve its investment goal.

Emerging Markets Equity Fund

GOAL AND STRATEGY

This is an emerging markets stock fund that seeks long-term growth in capital.

The Fund invests primarily in the stocks of companies in countries having econ-
omies or markets generally considered by the World Bank or United Nations to be
emerging or developing.

In making country allocation decisions, the manager analyzes the global envi-
ronment and selects countries with:

 . Improving macroeconomic, political and social trends, and

 . attractive valuation levels.

The manager selects stocks using fundamental proprietary research to identify
companies:

 . having strong earnings growth potential,

 . selling below their intrinsic value, and

 . having shareholder-focused management, dominant products, and well estab-
  lished distribution channels.

The Fund normally invests:

 . in at least 15 emerging market countries, and

 . no more than 30% of its assets in any single country.

The Fund normally invests in 100 to 250 stocks in 20 to 25 countries. The Fund
normally has 10% or less of its assets in cash and cash equivalents.

Although the Fund may employ foreign currency hedging techniques, the Fund
normally maintains the currency exposure of the underlying equity investments.

The Fund may purchase other types of securities, for example: American Deposi-
tory Receipts (ADRs), Global Depository Receipts (GDRs), European Depository
Receipts (EDRs), and certain derivatives (investments whose value is based on
indices or other securities).

In abnormal market conditions, the Fund may take temporary defensive measures--
such as holding unusually large amounts of cash and cash equivalents--that are
inconsistent with the Fund's primary investment strategy. In taking those mea-
sures, the Fund may not achieve its investment goal.

MAIN RISKS

Primary

Foreign Risk: The Fund's foreign securities will pose special risks, due to
limited government regulation, lack of public information, economic, political
and social instability and foreign currency rate fluctuations. Factors such as
lack of liquidity, foreign ownership limits and restrictions on removing cur-
rency also pose special risks. All foreign securities have some degree of for-
eign risk. However, since the Fund invests primarily in emerging market coun-
tries, it will have a significantly higher degree of foreign risk than funds
that invest primarily in developed or newly- industrialized countries.

Market Risk: The value of the securities in the Fund may go down in response to
overall stock or bond market movements. Markets tend to move in cycles, with
periods of rising prices and periods of falling prices. Stocks tend to go up
and down in value more than bonds. If the Fund's investments are concentrated
in certain sectors, the Fund's performance could be worse than the overall mar-
ket.

Manager Risk: The manager and its strategy may fail to produce the intended
results. The Fund could underperform its peers or lose money if the manager's
investment strategy does not perform as expected.

Turnover Risk: In general, the greater the volume of buying and selling by a
fund (i.e., the higher its "turnover rate"), the greater the impact that bro-
kerage commissions and other transaction costs will have on the funds perfor-
mance. Any turnover rate in excess of 100% is considered relatively high. The
Fund's turnover rate could be greater than 100% due to the relatively high vol-
atility associated with investing in emerging markets.

Secondary

Derivatives Risk: Certain derivative instruments (such as options, futures and
swaps) can produce disproportionate gains or losses. They are generally consid-
ered more risky than direct equity investments. Also, in a down market, deriva-
tives could become harder to value or sell at a fair price.

Short-Term Bond Fund

GOAL AND STRATEGY

This is a short-term bond fund that seeks high income consistent with low share
price fluctuation.

The Fund primarily invests in a diversified mix of short-term and intermediate-
term investment grade debt securities including:

 . U.S. Treasury and Agency securities;

 . U.S. corporate bonds;

 . foreign corporate bonds of companies in developed countries (if dollar-
  denominated);

 . foreign government and agency securities of developed countries (if dollar
  denominated); and

 . mortgage-and asset-backed securities.

The manager selects bonds using a combination of proprietary research and quan-
titative tools. Bonds are purchased that are attractively priced and that pro-
vide cheap, predictable cash flows.

The Fund normally invests:

 . mostly in corporate bonds;

 . no more than 15% of its assets in high yield bonds; and

 . no more than 25% of its assets in foreign debt securities.

The Fund normally has:

 . an average maturity between one and three and a half years;

 . an average credit quality rating of "A" or higher; and

 . 10% or less of its assets in cash and cash equivalents.

The Fund only invests in securities that are rated at least BB- or Ba3 at time
of purchase.

The Fund may purchase other types of securities, for example: certain deriva-
tives (investments whose value is based on indexes or other securities).

In abnormal market conditions, the Fund may take temporary defensive measures--
such as holding unusually large amounts of cash and cash equivalents--that are
inconsistent with the Fund's primary investment strategy. In taking those mea-
sures, the Fund may not achieve its investment goal.

MAIN RISKS

Primary

Market Risk: The value of the securities in the Fund may go down in response
to overall stock or bond market movements. Markets tend to move in cycles,
with periods of rising prices and periods of falling prices. Stocks tend to go
up and down in value more than bonds. If the Fund's investments are concen-
trated in certain sectors, the Fund's performance could be worse than the
overall market.

Manager Risk: The manager and its strategy may fail to produce the intended
results. The Fund could underperform its peers or lose money if the manager's
investment strategy does not perform as expected.

Interest Rate Risk: When interest rates rise, the Fund's bond yields will gen-
erally rise and the Fund's bond prices will generally fall. When interest
rates fall, the reverse will generally occur. The longer the average remaining
maturity of bonds held by the Fund, the more sensitive the Fund is to interest
rate risk. This Fund has less interest rate risk than an intermediate-term or
long-term bond fund.
Credit Risk: An issuer of a bond held by the Fund may default on its obliga-
tion to pay interest and repay principal. Also, the credit rating of a bond
held by the fund may be downgraded. In either case, the value of the bond held
by the Trust would fall. All bonds have some credit risk, but in general low-
er-rated bonds have higher credit risk.

Concentration Risk: The Fund's investment in securities of a smaller number of
issuers could produce more volatile performance relative to funds that invest
in a larger number of issuers. The more concentrated a fund's holdings are,
the more likely it is a specific security's poor performance will hurt the
fund significantly.

Turnover Risk: In general, the greater the volume of buying and selling by a
fund (i.e., the higher its "turnover rate"), the greater the impact that bro-
kerage commissions and other transaction costs will have on the fund's perfor-
mance. Any turnover rate in excess of 100% is considered relatively high. Nor-
mally, the Fund's turnover rate will be greater than 100%.
Secondary

Foreign Risk: The Fund's foreign securities will pose special risks, due to
limited government regulation, lack of public information, and economic,
political and social instability. Factors such as lack of liquidity, foreign
ownership limits and restrictions on removing currency also pose special
risks.

Derivatives Risk: Certain derivative instruments (such as options, futures and
swaps) can produce disproportionate gains or losses. They are generally con-
sidered more risky than direct equity investments. Also, in a down market,
derivatives could become harder to value or sell at a fair price.

High Yield Bond Risk: Junk bonds, defined as bond securities rated below BBB-
/Baa3, may be subject to more volatile or erratic price movements due to
investor sentiment. In a down market, these high yield securities become
harder to value or to sell at a fair price.

Prepayment / Call Risk: The Fund's share price or yield could be hurt if
interest rate movements cause the Fund's mortgage-related and callable securi-
ties to be paid off substantially earlier than expected.

Bond Index Fund

GOAL AND STRATEGY

This is a bond fund that seeks to track the performance of the Lehman Brothers
Government / Corporate Bond Index.

The manager employs a passive management strategy using quantitative techniques
to select individual securities that provide a representative sample of the
securities in the Index.

If the Fund reaches approximately $50 million in total assets, the manager will
seek to match the performance of the Lehman Brothers Aggregate Bond Index, a
broader market index that also includes mortgage-backed and asset-backed secu-
rities.

Both of these Indexes consist of dollar-denominated investment grade securities
with maturities greater than one year and outstanding par values of at least
$150 million issued primarily by:

 . the U.S. Treasury and U.S. government agencies and instrumentalities;

 . foreign governments and agencies; and

 . U.S. and foreign corporations.

The manager selects securities to match, as closely as practical, the Index's
duration, cash flow, sector, credit quality, callability, and other key perfor-
mance characteristics. The Fund may hold some cash and cash equivalents, but is
normally fully invested.
The Index composition may change from time to time. The manager may keep secu-
rities that no longer meet the Index criteria as long as:

 . such "ineligible" securities plus cash and money market instruments are less
  than 20% of the Fund's assets; and

 . high yield securities are less than 5% of the Fund's assets.

MAIN RISKS

Primary

Index Management Risk:  Certain factors such as the following may cause the
Fund to track the Index less closely:

 . The securities selected by the manager may not be fully representative of the
  Index.

 . Transaction expenses of the Fund may result in the Fund's performance being
  different than that of the Index.

 . The size and timing of the Fund's cash flows may result in the Fund's perfor-
  mance being different than that of the Index.

Also, index funds like this one will have more difficulty in taking defensive
positions in abnormal market conditions.

Market Risk: The value of the securities in the Fund may go down in response to
overall stock or bond market movements. Markets tend to move in cycles, with
periods of rising prices and periods of falling prices. Stocks tend to go up
and down in value more than bonds. If the Fund's investments are concentrated
in certain sectors, the Fund's performance could be worse than the overall mar-
ket.

Manager Risk: The manager and its strategy may fail to produce the intended
results. The Fund could underperform its peers or lose money if the manager's
investment strategy does not perform as expected.

Interest Rate Risk: When interest rates rise, the Fund's bond yields will gen-
erally rise and the Fund's bond prices will generally fall. When interest rates
fall, the reverse will generally occur. The longer the average remaining matu-
rity of bonds held by the Fund, the more sensitive the Fund is to interest rate
risk. This Fund has more interest rate risk than a short-term bond fund, but
less interest rate risk than a long-term bond fund.

Credit Risk: An issuer of a bond held by the Fund may default on its obligation
to pay interest and repay principal. Also, the credit rating of a bond held by
the fund may be downgraded. In either case, the value of the bond held by the
Trust would fall. All bonds have some credit risk, but in general lower-rated
bonds have higher credit risk.

Secondary

Foreign Risk: The Fund's foreign securities will pose special risks, due to
limited government regulation, lack of public information, and economic, polit-
ical and social instability. Factors such as lack of liquidity, foreign owner-
ship limits and restrictions on removing currency also pose special risks. All
foreign securities have some degree of foreign risk. However, to the extent the
Fund invests in emerging market countries, it will have a significantly higher
degree of foreign risk than if it invested exclusively in developed or newly-
industrialized countries.

Global Bond Fund

GOAL AND STRATEGY

This is a global bond fund that seeks income and growth in capital.

The Fund primarily invests in a mix of debt securities of developed countries
throughout the world including:

 . U.S. Treasury and agency securities;

 . foreign government and agency securities;

 . supranational securities (such as the World Bank);

 . corporate bonds, both U.S. and foreign; and

 . mortgage-backed and asset-backed securities.

The manager makes ongoing decisions regarding the Fund's mix of U.S. bonds and
non-U.S. bonds (denominated in foreign currencies). The manager has a target
mix of 35% U.S. bonds and 65% non-U.S. bonds, but actively manages the mix
within (+/-) 50 percentage points of the target mix.

The Fund invests in at least 3 countries, but normally in 5 to 15 countries.
The Fund normally has an average credit quality rating of "AA" or higher.

The manager makes ongoing decisions regarding the Fund's average maturity,
country and sector allocations and foreign currency exposures. The manager uses
proprietary research and economic analysis to try to anticipate market condi-
tions and interest rate movements and to purchase securities that appear com-
paratively undervalued.

The manager actively uses derivatives (investments whose value is based on
indices or other securities) such as futures, forwards, options and swaps to
adjust the Fund's average maturity and to implement currency strategies. The
Fund is typically 75% to 100% hedged to the U.S. dollar.

The manager actively uses cash and cash equivalents to manage the Fund's aver-
age maturity. However, the Fund normally invests 20% or less of its assets in
cash and cash equivalents.

The Fund may purchase other types of securities, for example: high yield debt
securities and emerging market debt securities.

In abnormal market conditions, the Fund may take temporary defensive measures--
such as holding unusually large amounts of cash and cash equivalents--that are
inconsistent with the Fund's primary investment strategy. In taking those mea-
sures, the Fund may not achieve its investment goal.

PAST PERFORMANCE

The graph shows how the fund's total return has varied from year to year, while
the table shows performance over time (along with a broad-based market index
for reference). This information may help provide an indication of the fund's
risks and potential rewards. All figures assume dividend reinvestment. Past
performance does not indicate future results. The performance figures below do
not reflect the deduction of fees and charges payable under the variable
contracts. Such fees and charges would cause the investment returns under the
contracts to be less than that shown below.

MAIN RISKS

Primary

Foreign Risk: The Fund's foreign securities will pose special risks, due to
limited government regulation, lack of public information, economic, political
and social instability and foreign currency rate fluctuations. Factors such as
lack of liquidity, foreign ownership limits and restrictions on removing cur-
rency also pose special risks. All foreign securities have some degree of for-
eign risk. However, the Fund's investments in emerging market countries have a
significantly higher degree of foreign risk than investments in developed or
newly-industrialized countries.

Market Risk: The value of the securities in the Fund may go down in response to
overall stock or bond market movements. Markets tend to move in cycles, with
periods of rising prices and periods of falling prices. Stocks tend to go up
and down in value more than bonds. If the Fund's investments are concentrated
in certain sectors, the Fund's performance could be worse than the overall mar-
ket.

Manager Risk: The manager and its strategy may fail to produce the intended
results. The Fund could underperform its peers or lose money if the manager's
investment strategy does not perform as expected.

Interest Rate Risk: When interest rates rise, the Fund's bond yields will gen-
erally rise and the Fund's bond prices will generally fall. When interest rates
fall, the reverse will generally occur. The longer the average remaining matu-
rity of bonds held by the Fund, the more sensitive the Fund is to interest rate
risk. This Fund has more interest rate risk than a short-term bond fund, but
less interest rate risk than a long-term bond fund.

Credit Risk: An issuer of a bond held by the Fund may default on its obligation
to pay interest and repay principal. Also, the credit rating of a bond held by
the fund may be downgraded. In either case, the value of the bond held by the
Trust would fall. All bonds have some credit risk, but in general lower-rated
bonds have higher credit risk.

Concentration Risk: The Fund's investment in securities of a smaller number of
issuers could produce more volatile performance relative to funds that invest
in a larger number of issuers. The more concentrated a fund's holdings are, the
more likely it is a specific securities poor performance will hurt the fund
significantly.

Turnover Risk: In general, the greater the volume of buying and selling by a
fund (i.e., the higher its "turnover rate"), the greater the impact that bro-
kerage commissions and other transaction costs will have on the fund's perfor-
mance. Any turnover rate in excess of 100% is considered relatively high. Nor-
mally, the Fund's turnover rate will be greater than 100%.

Secondary

Derivatives Risk: Certain derivative instruments (such as options, futures and
swaps) can produce disproportionate gains or losses. They are generally consid-
ered more risky than direct equity investments. Also, in a down market, deriva-
tives could become harder to value or sell at a fair price.

High Yield Bond Fund

GOAL AND STRATEGY

This is a high yield bond fund that seeks high income and growth in capital.

The Fund invests primarily in a diversified mix of high yield debt securities,
commonly referred to as "junk bonds" (rated BB+/Ba1 or lower and their unrated
equivalents), including:

 . corporate bonds, both U.S. and foreign (if dollar-denominated);

 . foreign government and agency securities (if dollar-denominated);

 . preferred stocks; and

 . convertible securities (convertible into common stocks or other equity inter-
  ests).

The manager will invest no more than 15% of the Fund's assets in emerging mar-
ket countries (with below investment-grade sovereign debt). The Fund normally
has 10% or less of its assets in cash and cash equivalents.

The manager seeks to purchase bonds with stable or improving credit quality
before the market widely perceives the improvement. Purchase and sale decisions
are primarily based upon the investment merits of the particular security.

The manager selects bonds using proprietary research, including:

 . quantitative analysis of historical financial data;

 . qualitative analysis of a company's future prospects; and

 . economic and industry analysis.

The Fund's average maturity depends on security selection decisions rather than
interest rate decisions.

The Fund may purchase other types of securities, for example: equity securi-
ties, high quality debt securities (short-term and otherwise), certain deriva-
tives (investments whose value is based on indices or other securities), and
debt securities denominated in foreign currencies.

In abnormal market conditions, the Fund may take temporary defensive measures--
such as holding unusually large amounts of cash and cash equivalents--that are
inconsistent with the Fund's primary investment strategy. In taking those mea-
sures, the Fund may not achieve its investment goal.

MAIN RISKS

Primary

High Yield Bond Risk: High yield or junk bonds, defined as bond securities
rated below BBB-/Baa3, may be subject to more volatile or erratic price move-
ments due to investor sentiment. In a down market, these high yield securities
may become harder to value or to sell at a fair price.

Market Risk: The value of the securities in the Fund may go down in response to
overall stock or bond market movements. Markets tend to move in cycles, with
periods of rising prices and periods of falling prices. Stocks tend to go up
and down in value more than bonds. If the Fund's investments are concentrated
in certain sectors, the Fund's performance could be worse than the overall mar-
ket.

Manager Risk: The manager and its strategy may fail to produce the intended
results. The Fund could underperform its peers or lose money if the manager's
investment strategy does not perform as expected.
Interest Rate Risk: When interest rates rise, the Fund's bond yields will gen-
erally rise and the Fund's bond prices will generally fall. When interest rates
fall, the reverse will generally occur. The longer the average remaining matu-
rity of bonds held by the Fund, the more sensitive the Fund is to interest rate
risk. This Fund has more interest rate risk than a short-term bond fund, but
less interest rate risk than a long-term bond fund.

Credit Risk: An issuer of a bond held by the Fund may default on its obligation
to pay interest and repay principal. Also, the credit rating of a bond held by
the fund may be downgraded. In either case, the value of the bond held by the
Fund would fall. All bonds have some credit risk, but in general lower-rated
bonds have higher credit risk.

Secondary

Foreign Risk: The Fund's foreign securities will pose special risks, due to
limited government regulation, lack of public information, and economic, polit-
ical and social instability. Factors such as lack of liquidity, foreign owner-
ship limits and restrictions on removing currency also pose special risks. All
foreign securities have some degree of foreign risk. However, to the extent the
Fund invests in emerging market countries, it will have a significantly higher
degree of foreign risk than if it invested exclusively in developed or newly-
industrialized countries.

swaps) can produce disproportionate gains or losses. They are generally consid-
ered more risky than direct equity investments. Also, in a down market, deriva-
tives could become harder to value or sell at a fair price.

Prepayment/Call Risk: The Fund's share price or yield could be hurt if interest
rate movements cause the Fund's mortgage-related and callable securities to be
paid off substantially earlier than expected.

Your Account

Investments in shares of the funds

Each fund sells its shares directly to separate accounts of John Hancock,
JHVLICO and IPL to fund variable contracts. Each fund also buys back its shares
on redemption by the separate accounts.

Under the variable contracts, a separate account buys or redeems a fund's
shares based on:

 . instructions by you and other contractowners to invest or receive back monies
  under a contract (such as making a premium payment or surrendering a con-
  tract), and

 . the operation of a contract (such as deduction of fees and charges).

The Trust, as law permits, may:

 . refuse a buy order if the adviser believes it would disrupt management

 . suspend a fund's offer of shares, or

 . suspend a fund's redemption obligation or postpone a fund's payment of
  redemption proceeds for more than seven days.

Share price

Each fund sells and buys back its shares at the net asset value per share
("NAV") next computed after receipt by a separate account of a contractowner's
instructions.

Each fund calculates its NAV:

 . by dividing its net assets by the number of its outstanding shares,

 . once daily as of the close of regular trading on the New York Stock Exchange
  (generally at 4 p.m. New York time) on each day the Exchange is open.

Certain funds may hold securities primarily listed on foreign exchanges that
trade on weekends or other days when the Trust does not calculate NAV. Conse-
quently, NAV may change on days when contractowners will not be able to
instruct a separate account to buy or redeem fund shares.

Valuation

Each of the funds values securities based on:

 . market quotations,

 . amortized cost,

 . valuations of independent pricing services, or

 . fair value determined in accordance with procedures approved by the Trust's
  trustees.

A fund may value securities at fair value where, for example:

 . market quotations are not readily available, or

 . the value of securities has been materially affected after the closing of a
  foreign market.

Conflicts

The Trust's trustees monitor for possible material irreconcilable conflicts
among separate accounts buying shares of the funds. The Trust's net asset value
could decrease, if the Trust had to sell investment securities to pay redemp-
tion proceeds to a separate account withdrawing because of a conflict.

The adviser pays subadvisory fees out of its own assets. No fund pays a fee to
its subadviser.

The adviser has agreed to limit each fund's annual expenses (excluding advisory
fees and certain other expenses such as brokerage and taxes) to not more than
 .10 percent of the fund's average daily net assets.

Dividends and Taxes

Dividends

Each fund automatically reinvests its dividends and distributions in additional
shares of the fund at NAV.

Each fund declares and pays dividends monthly.

Funds generally declare capital gains distributions annually.

Taxes

Each fund must meet investment diversification and other requirements under the
Internal Revenue Code, in order to:

 . avoid federal income tax and excise tax, and

 . assure the tax-deferred treatment of variable contracts under the Code.

You should read the prospectus for your variable contract for the federal
income tax consequences for contractowners, including the consequences of a
fund's failure to meet Code requirements.

APPENDIX

Additional Performance Information

The "Past Performance" information shown earlier in this prospectus for certain
of the Funds may not be sufficient for you to make a complete assessment of the
risks and potential rewards of investing in those Funds. The Small/Mid Cap CORE
Fund, the Emerging Markets Equity Fund, the Bond Index Fund, and the High Yield
Bond Fund only began operations on May 1, 1998. The Global Balanced Fund and
the Global Bond Fund implemented significant changes in strategy as of May 1,
2000, and May 1, 1999, respectively.

Since each of these Funds has at best a very limited period of relevant perfor-
mance history, we have set forth below information for certain similar accounts
that are managed by the Funds' respective subadvisers. Each grouping of such
accounts is referred to as a "composite." In the case of each account included
in a composite, the total management fees and other operating expenses of the
Fund (based upon management fee schedules and allocation rules currently in
effect) have been substituted for the actual fees and expenses (other than bro-
kerage and other transaction expenses) of the account. Also, except as specifi-
cally noted below, each composite includes all of the investment company and
other accounts of the subadviser that satisfy the following requirements:

 . they have been managed with investment objectives, policies, and strategies
  substantially similar to those used in managing the Fund, and

 . they are of sufficient size that their performance would be considered rele-
  vant to the owner of a variable contract investing in that Fund.

Some of the accounts in the composites were not registered investment companies
and, therefore, were not subject to federal income tax and other legal require-
ments applicable to such companies. Had such accounts been subject to such
requirements, their performance could have been adversely affected. The perfor-
mance figures in this Appendix do not reflect the deduction of fees and charges
payable under the variable contracts. Such fees and charges would cause the
investment returns under the contacts to be less than that shown below.

The graphs below show how the composite's total return has varied from year to
year, while the tables show performance over time (along with a broad-based
index for reference). All figures assume dividend reinvestment. Past perfor-
mance does not indicate future results.

Small/Mid Cap CORE Composite (Corresponding to Small/Mid Cap CORE Fund)

The Small/Mid Cap CORE Composite is an asset-weighted composite of all fully
discretionary accounts managed using a substantially similar investment strate-
gy. As of December 31, 1999, the composite included 4 accounts with total

Overview

FUND INFORMATION KEY
Concise fund-by-fund descriptions begin on page 6. Each description provides
the following information:

Goal and Strategy The fund's particular investment goals and the principal
strategies it intends to use in pursuing those goals.

Subadviser/Manager The firm and individual(s) providing investment management
services to the fund.

Past Performance The fund's total return, measured year-by-year and over time.

Main Risks The significant risk factors associated with the fund. The risks are
categorized as "Primary" or "Secondary". The Primary Risks are considered major
factors in the fund's performance and are described first. The Secondary Risks
are not considered major factors in the fund's performance because the fund
would not normally commit a large portion of its assets to the investments
involved. However, the Secondary Risks are of such a nature that they could
significantly affect the fund's performance, even if the investments are held
in relatively small amounts.

Financial Highlights The fund's operating performance per share, measured year-
by-year.
THE FUNDS
The Trust offers investment choices, or funds, for the variable annuity and
variable life insurance contracts ("variable contracts") of:

 . John Hancock Life Insurance Company ("John Hancock"),

 . John Hancock Variable Life Insurance Company ("JHVLICO"), and

 . Investors Partner Life Insurance Company and its subsidiaries ("IPL").

In some variable contract forms, the Trust is referred to as the "Fund" or "Se-
ries Fund" and the investment choices are referred to as "Portfolios."

RISKS OF FUNDS
These funds, like all mutual funds, are not bank deposits. They are not insured
or guaranteed by the FDIC or any other government agency. You could lose money
by investing in these funds. So, be sure to read all risk disclosure carefully
before investing.

MANAGEMENT
John Hancock is the investment adviser of each fund. John Hancock is a Massa-
chusetts stock life insurance company. On February 1, 2000, John Hancock
changed its form of organization and its name. Prior to that date, it was John
Hancock Mutual Life Insurance Company, a mutual life insurance company that was
chartered in 1862. At the end of 1999, John Hancock managed approximately $127
billion, of which it owned over $71 billion. All of the funds shown in this
prospectus have subadvisers.

Your Investment Choices

- -------------------------------------------------------------------------------
The Trust offers a number of investment choices, or funds, to suit a variety
of objectives under variable contracts. There are 17 of these funds available
under your variable contract. Each fund has its own strategy and its own
risk/reward profile. The funds can be broadly categorized as equity funds,
balanced funds, bond funds, and international funds. Within these broad cate-
gories, the funds can be further categorized as follows:

Equity Funds
Equity funds can be categorized in two ways--by capitalization and by invest-
ment style.

Capitalization             Equity funds can be categorized by market capital-
                           ization, which is defined as the market value of
                           all shares of a company's stock. The following def-
                           initions for large, mid and small cap are based
                           upon statistics at year-end 1999, but are adjusted
                           periodically with broad equity market movements as
                           represented by the Russell 3000(R) Index or other
                           widely-
                           recognized source of market capitalization data.
                           Adjustments are typically made on a quarterly
                           basis, but in extraordinary circumstances may be
                           made as frequently as monthly.

                           Large Cap Funds:
 . Equity Index Fund        These funds invest in large, well-established com-
                           panies that typically are very actively traded and
 . Large Cap Value CORE     provide more stable investment returns over time.
  Fund                     Large cap companies represent the 300 largest
                           stocks in the Russell 3000(R) Index. Each of those
 . Large Cap Aggressive     companies has a market capitalization greater than
  Growth Fund              $7.9 billion as of the end of 1999. Large cap funds
                           are appropriate for investors who want the least
                           volatile investment returns within the overall
                           equity markets.

                           Large/Mid Cap Funds:
 . Large/Mid Cap Value      These funds invest in large cap and mid cap compa-
  Fund                     nies. The capitalization of these funds can shift
                           over time from primarily large cap to primarily mid
                           cap or vice versa depending on where the manager
                           identifies investment opportunities. These funds
                           are generally more volatile than pure large cap
                           funds, but generally less volatile than pure mid
                           cap funds.

                           Mid Cap Funds:
 . Mid Cap Blend Fund       These funds invest in medium-sized, less estab-
                           lished companies that are less actively traded and
 . Mid Cap Growth Fund      provide more share price volatility over time than
                           large cap stocks. Mid cap companies represent the
 . Fundamental Mid Cap      250th to 1000th largest stocks in the Russell
  Growth Fund              3000(R) Index. Each of those companies has a market
                           capitalization between $1.4 billion and $9.7 bil-
                           lion as of the end of 1999. Mid cap funds are
                           appropriate for investors who are willing to accept
                           more volatile investment returns within the overall
                           equity markets with the potential reward of higher
                           long-term returns.

                           Small/Mid Cap Funds:
 . Small/Mid Cap CORE Fund  These funds invest in mid cap and small cap compa-
                           nies. The capitalization of these funds can shift
 . Small/Mid Cap Value      over time from primarily mid cap to primarily small
  Fund                     cap or vice versa depending on where the manager
                           identifies investment opportunities. These funds
 . Small/Mid Cap Growth     are generally more volatile than pure mid cap
  Fund                     funds, but generally less volatile than pure small
                           cap funds.

                           Small Cap Funds:
 . Small Cap Growth Fund    These funds invest in small newly established com-
                           panies that are less actively traded and have a
                           high level of share price volatility over time.
                           Small cap companies represent the 2000 smallest
                           stocks in the Russell 3000(R) Index. Each of those
                           companies has a market capitalization of less than
                           $1.4 billion as of the end of 1999. Small cap funds
                           are appropriate for investors who are willing to
                           accept the most volatile investment returns within
                           the overall equity markets for the potential reward
                           of higher long-term returns.

                                                                              3

Investment Style

                           Value Funds:
 . Large Cap Value CORE     Value funds invest in companies that are attrac-
  Fund                     tively priced, considering their asset and earnings
                           history. These stocks typically pay above average
 . Large/Mid Cap Value      dividends and have low stock prices relative to
  Fund                     measures of earnings and book value. Value funds
                           are appropriate for investors who want some divi-
 . Small/Mid Cap Value      dend income and the potential for capital gains,
  Fund                     but are less tolerant of share-price fluctuations.

                           Growth Funds:
 . Large Cap Aggressive     Growth funds invest in companies believed to have
Growth Fund                above-average prospects for capital growth due to
                           their strong earnings and revenue potential. Growth
 . Mid Cap Growth Fund      stocks typically have high stock prices relative to
                           measures of earnings and book value. Growth funds
 . Fundamental Mid Cap      are appropriate for investors who are willing to
  Growth Fund              accept more share-price volatility for the poten-
                           tial reward of higher long-term returns.
 . Small Mid/Cap Growth
  Fund

 . Small Cap Growth Fund

                           Blend Funds:
 . Equity Index Fund        Blend funds invest in both value and growth compa-
                           nies. Blend funds are appropriate for investors who
 . Mid Cap Blend Fund       seek both dividend and capital appreciation charac-
                           teristics.
 . Small/Mid Cap CORE Fund

Balanced Funds

 . Aggressive Balanced      Balanced funds invest in a combination of stocks
  Fund                     and bonds and actively manage the mix of stock and
                           bonds within a target range. Domestic balanced
 . Global Balanced Fund     funds invest in U.S. stocks and bonds. Global bal-
                           anced funds invest in foreign and U.S. stocks and
                           bonds.

Bond Funds
Bond funds can be categorized in two ways--by average maturity and by credit
quality:

Average Maturity           Bond maturity is a key measure of interest rate
                           risk. A bond's maturity measures the time remaining
                           until the bond matures, or until the repayment of
                           the bond's principal comes due. The longer a bond's
                           maturity, the more sensitive the bond's price is to
                           changes in interest rates.

                           Short:
 . Short Term Bond Fund     These funds invest primarily in bonds with short
                           maturities, typically less than four years. These
                           funds have less interest rate risk than intermedi-
                           ate-term bond funds.

                           Intermediate:
 . Bond Index Fund          These funds invest in bonds of all maturities and
                           maintain an average maturity which is typically
 . High Yield Bond Fund     between four and ten years. These funds have more
                           interest rate risk than short-term bond funds.

Credit Quality             Credit quality is a measure of the ability of a
                           bond issuer to meet its financial obligations and
                           repay principal and interest. High quality bonds
                           have less credit risk than lower quality bonds.
                           Investment grade bonds typically have "high" or
                           "medium" credit quality ratings (as defined below),
                           while high-yield bonds have "low" credit quality
                           ratings.

                           High:
 . Bond Index Fund          These funds focus on the highest-rated, most
                           creditworthy bonds and typically maintain an aver-
                           age credit quality rating of AAA/Aaa or AA/Aa.

                           Medium:
 . Short Term Bond Fund     These funds invest in bonds of all credit quality
                           levels with a focus on high-rated investment grade
                           bonds. These funds typically maintain an average
                           credit quality rating of A or BBB/Baa.

                           Low:
 . High Yield Bond Fund     These funds invest primarily in lower rated bonds--
                           known as high yield or "junk" bonds. These funds
                           typically maintain a below investment-grade average
                           credit quality rating of BB/Ba or B.

International Funds
International funds invest primarily in securities markets outside the United
States. Funds that invest primarily in the larger, well-established developed
or industrialized markets around the world (like the International Equity Fund)
have less foreign securities risk than funds that invest primarily in emerging
markets.

In the following pages, any fund investment strategy that is stated as a per-
centage of a fund's assets applies at all times, not just at the time the fund
buys or sells an investment security. The trustees of the Trust can change the
investment goals and strategy of any fund without shareholder (i.e.,
contractowner) approval.

The financial highlights tables on the following pages detail the historical
performance of each fund that had at least one full year of operations as of
December 31, 1999, including total return information showing the increase or
decrease of an investment in the fund each year (assuming reinvestment of all
dividends and distributions). The "total investment return" shown for each fund
does not reflect the expenses and charges of the applicable separate accounts
and variable contracts. Those expenses and charges vary considerably from con-
tract to contract and are described in the variable contract prospectus to
which this prospectus is attached. If the earliest period shown in the finan-
cial highlights table is less than a full calendar year, the two "Ratios" shown
for that period have been annualized (i.e., projected as if the fund had been
in effect for a full year). However, the "total investment return" and "turn-
over rate" for that period have not been annualized.

In this prospectus, the term "stock" is used as a shorthand reference for
equity investments generally and the term "bond" is used as a shorthand refer-
ence for debt obligations generally.

                                                                               5

Aggressive Balanced Fund

GOAL AND STRATEGY

This is a balanced stock and bond fund that seeks long-term growth in income
and capital.

The Fund invests primarily in a diversified mix of:

 . common stocks of large established U.S. companies, and

 . bonds with maturities generally greater than 12 months.

The manager makes ongoing decisions about the mix among stocks and bonds. The
manager has a target mix of 75% in equities and 25% in bonds, but actively man-
ages the mix within +/-10 percentage points of the target mix.

The manager selects stocks and bonds using a combination of proprietary
research and quantitative tools. Stocks are purchased that are undervalued rel-
ative to the stock's history and have improving earnings growth prospects.
Bonds are purchased that are attractively priced and have cheap, predictable
cash flows. The Fund is managed using risk control techniques that maintain
risk and industry characteristics similar to the overall market.

The Fund normally invests its equity portion in 80 to 150 stocks, with at least
65% (usually higher) of its equity assets in large cap companies. The Fund may
invest up to 20% of its bond assets in developed foreign countries (denominated
in foreign currencies) and up to 15% of its bond assets in high yield bonds.
The Fund normally has 5% or less of its assets in cash and cash equivalents.

The Fund may purchase other types of securities, for example: American Deposi-
tory Receipts (ADRs), and certain derivatives (investments whose value is based
on indices or other securities). The manager actively uses derivatives, such as
futures and forwards, to adjust the Fund's average maturity relative to the
Lehman Brothers Aggregate Bond Index and to implement currency strategies.

In abnormal market conditions, the Fund may take temporary defensive measures--
such as holding unusually large amounts of cash and cash equivalents--that are
inconsistent with the Fund's primary investment strategy. In taking those mea-
sures, the Fund may not achieve its investment goal.

PAST PERFORMANCE

Because this Fund did not have a full year of operations as of December 31,
1999, no year-by-year total returns or average annual total returns can be
shown for this Fund. However, the Appendix to this prospectus contains certain
performance information that is relevant to this Fund. The Appendix starts on
page 43.

<PAGE>

MAIN RISKS
Primary


Market Risk: The value of the securities in the Fund may go down in response
to overall stock or bond market movements. Markets tend to move in cycles,
with periods of rising prices and periods of falling prices. Stocks tend to go
up and down in value more than bonds. If the Fund's investments are concen-
trated in certain sectors, the Fund's performance could be worse than the
overall market.


Manager Risk: The manager and its strategy may fail to produce the intended
results. The Fund could underperform its peers or lose money if the manager's
investment strategy does not perform as expected.


Investment Category Risk: The returns of the Fund's specific equity investment
category may lag the returns of the overall stock market. For example, the
Fund's "large cap" approach carries the risk that in certain markets large cap
stocks will underperform mid cap and small cap stocks.


Interest Rate Risk: When interest rates rise, the Fund's bond yields will gen-
erally rise and the Fund's bond prices will generally fall. When interest
rates fall, the reverse will generally occur. The longer the average remaining
maturity of bonds held by the Fund, the more sensitive the Fund is to interest
rate risk. This Fund has more interest rate risk than a short-term bond fund,
but less interest rate risk than a long-term bond fund.


Credit Risk: An issuer of a bond held by the Fund may default on its obliga-
tion to pay interest and repay principal. Also, the credit rating of a bond
held by the fund may be downgraded. In either case, the value of the bond held
by the Trust would fall. All bonds have some credit risk, but in general low-
er-rated bonds have higher credit risk.


Market Allocation Risk: The allocation of the Fund's assets among major asset
classes (i.e., stocks, bonds, and short-term debt securities) may (1) reduce
the Fund's holdings in a class whose value then increases unexpectedly, or (2)
increase the Fund's holdings in a class just prior to its experiencing a loss
of value.


Turnover Risk: In general, the greater the volume of buying and selling by a
fund (i.e., the higher its "turnover rate"), the greater the impact that bro-
kerage commissions and other transaction costs will have on the fund's perfor-
mance. Any turnover rate in excess of 100% is considered relatively high. Nor-
mally, the Fund's turnover rate will be greater than 100%.


Secondary


Foreign Risk: The Fund's foreign securities will pose special risks, due to
limited government regulation, lack of public information, economic, political
and social instability and foreign currency rate fluctuations. Factors such as
lack of liquidity, foreign ownership limits and restrictions on removing cur-
rency also pose special risks. All foreign securities have some degree of for-
eign risk.


Derivatives Risk: Certain derivative instruments (such as options, futures and
swaps) can produce disproportionate gains or losses. They are generally con-
sidered more risky than direct equity investments. Also, in a down market,
derivatives could become harder to value or sell at a fair price.


High Yield Bond Risk: Junk bonds, defined as bond securities rated below BBB-
/Baa3, may be subject to more volatile or erratic price movements due to
investor sentiment. In a down market, these high yield securities become
harder to value or to sell at a fair price.


Prepayment/Call Risk: The Fund's share price or yield could be hurt if inter-
est rate movements cause the Fund's mortgage-related and callable securities
to be paid off substantially earlier than expected.

Equity Index Fund

GOAL AND STRATEGY

This is a stock fund that seeks to track the performance of the S&P 500 Index,
which emphasizes the stocks of large U.S. companies.

The manager employs a passive management strategy by normally investing in all
500 stocks included in the Index. The manager invests in each stock in roughly
the same proportion as represented in the Index.

The manager seeks to replicate as closely as possible the aggregate risk char-
acteristics and industry diversification of the Index.

The Fund normally invests in all 500 stocks in the Index, but has no predeter-
mined number of stocks that it must hold. S&P may change the composition of the
Index from time to time. The manager will reflect those changes as soon as
practical.

The Fund is normally fully invested. The manager may invest in stock index
futures to maintain market exposure and manage cash flow.

The Fund may purchase other types of securities, for example: Standard & Poor's
Depository Receipts (SPDRs), American Depository Receipts (ADRs), cash equiva-
lents, and certain derivatives (investments whose value is based on indices or
other securities).

Note: "S&P 500 Index" means the Standard & Poor's 500 Composite Stock Price
Index. "Standard & Poor's", "S&P" and "S&P 500" are trademarks of McGraw Hill,

PAST PERFORMANCE

The graph shows how the fund's total return has varied from year to year, while
the table shows performance over time (along with a broad-based market index
for reference). This information may also help provide an indication of the
fund's risks and potential rewards. All figures assume dividend reinvestment.
Past performance does not indicate future results. The performance figures
below do not reflect the deduction of fees and charges payable under the
variable contracts. Such fees and charges would cause the investment returns
under the contracts to be less than that shown below.

MAIN RISKS

Primary

Index Management Risk:  Certain factors such as the following may cause the
Fund to track the Index less closely:

 . The securities selected by the manager may not be fully representative of
  the Index.

 . Transaction expenses of the Fund may result in the Fund's performance being
  different than that of the Index.

 . The size and timing of the Fund's cash flows may result in the Fund's per-
  formance being different than that of the Index.
Also, index funds like this one will have more difficulty in taking defensive
positions in abnormal market conditions.

Market Risk: The value of the securities in the Fund may go down in response
to overall stock or bond market movements. Markets tend to move in cycles,
with periods of rising prices and periods of falling prices. Stocks tend to go
up and down in value more than bonds. If the Fund's investments are concen-
trated in certain sectors, the Fund's performance could be worse than the
overall market.

Manager Risk: The manager and its strategy may fail to produce the intended
results. The Fund could underperform its peers or lose money if the manager's
investment strategy does not perform as expected.

Investment Category Risk: The returns of the Fund's specific equity investment
category may lag the returns of the overall stock market. For example, the
Fund's "large cap" approach carries the risk that in certain markets large cap
stocks will underperform mid cap and small cap stocks.

Large Cap Value CORE Fund

GOAL AND STRATEGY

This is a large cap stock fund with a value emphasis that seeks long-term
growth in capital and dividend income.

The Fund invests primarily in a diversified mix of common stocks of large
established U.S. companies that are believed to offer favorable prospects for
increasing dividends and growth in capital.

The manager selects stocks using a combination of quantitative techniques and
fundamental equity research. The manager employs an investment process known as
CORE, "Computer Optimized, Research-Enhanced," that employs a proprietary quan-
titative model. The manager identifies stocks that have strong expected earn-
ings growth and momentum and better valuation and risk characteristics than the
Russell 1000 Value Index.

Stocks are purchased that have:

 . Low to modest valuation characteristics relative to general market measures,
  such as price/earnings ratio, book value and other fundamental accounting
  measures, and

 . favorable prospects for capital appreciation and/or dividend paying ability.

The Fund is managed using risk control techniques to maintain risk, style, cap-
italization and industry characteristics similar to the Russell 1000(R) Value
Index. The Fund is broadly diversified by industry.

The Fund normally invests in 100 to 250 stocks, with at least 65% (usually
higher) of the Fund's assets in large cap companies. The Fund normally has 10%
or less of its assets in cash and cash equivalents.

The Fund may purchase other types of securities, for example: American Deposi-
tory Receipts (ADRs), Standard & Poor's Depository Receipts (SPDRs), and cer-
tain derivatives (investments whose value is based on indices or other securi-
ties).

In abnormal market conditions, the Fund may take temporary defensive measures--
such as holding unusually large amounts of cash and cash equivalents--that are
inconsistent with the Fund's primary investment strategy. In taking those mea-
sures, the Fund may not achieve its investment goal.

Market Risk: The value of the securities in the Fund may go down in response to
overall stock or bond market movements. Markets tend to move in cycles, with
periods of rising prices and periods of falling prices. Stocks tend to go up

Large Cap Aggressive Growth Fund

GOAL AND STRATEGY

This is a non-diversified large cap stock fund with a growth emphasis that
seeks long-term growth in capital.

The Fund invests primarily in the common stocks of large established U.S. com-
panies that are believed to offer above-average potential for long-term growth
in revenues and earnings.

The manager selects stocks using proprietary company-specific research that
focuses on firms:

 . offering superior earnings growth that is not fully reflected in current mar-
  ket valuations,

 . having prospective earnings growth rates substantially above that of the S&P
  500, and

 . exhibiting strong management, superior industry positions and excellent bal-
  ance sheets.

The Fund employs aggressive investment strategies and invests most of its asset
in a relatively small number of companies, with the 25 most highly regarded
stocks representing at least 65% of the Fund's assets. The manager selects
stocks without regard to any predefined industry or sector selection criteria.

The manager actively trades and adjusts the Fund's holdings to capitalize on
market fluctuations. The manager typically:

 . increases investment in favored securities and reduces the number of holdings
  in declining markets, and

 . decreases investment in favored securities and increases the number of hold-
  ings in rising markets.

The Fund is a non-diversified fund, which means it can take larger positions in
a smaller number of issuers. The Fund normally invests in 35 to 55 stocks, with
at least 65% (usually higher) of its assets in large cap companies. The Fund
normally has 5% or less of its assets in cash and cash equivalents.

The Fund may purchase other types of securities, for example: American Deposi-
tory Receipts (ADRs), and certain derivatives (investments whose value is based
on indices or other securities).

In abnormal market conditions, the Fund may take temporary defensive measures--
such as holding unusually large amounts of cash and cash equivalents--that are
inconsistent with the Fund's primary investment strategy. In taking those mea-
sures, the Fund may not achieve its investment goal.

PAST PERFORMANCE

Because this Fund did not have a full year of operations as of December 31,
1999, no year-by-year total returns or average annual total returns can be
shown for this Fund. However, the Appendix to this prospectus contains certain
performance information that is relevant to this Fund. The Appendix starts on
page 43.

<PAGE>


MAIN RISKS

Primary

Market Risk: The value of the securities in the Fund may go down in response to
overall stock or bond market movements. Markets tend to move in cycles, with
periods of rising prices and periods of falling prices. Stocks tend to go up
and down in value more than bonds. If the Fund's investments are concentrated
in certain sectors, the Fund's performance could be worse than the overall mar-
ket.

Non-Diversified Fund Risk: The Fund's larger position in individual issuers and
in a smaller number of issuers could produce more volatile performance relative
to more diversified funds. The less diversified a fund's holdings are, the more
likely it is that a specific security's poor performance will hurt the fund
significantly.

Manager Risk: The manager and its strategy may fail to produce the intended
results. The Fund could underperform its peers or lose money if the manager's
investment strategy does not perform as expected.

Investment Category Risk: The returns of the Fund's specific equity investment
category may lag the returns of the overall stock market. For example, the
Fund's "growth" approach carries the risk that in certain markets "growth"
stocks will underperform "value" stocks. Also, the Fund's "large cap" approach
carries the risk that large cap stocks will underperform small cap and mid cap
stocks.

Concentration Risk: The Fund's investment in securities of a smaller number of
issuers could produce more volatile performance relative to funds that invest
in a larger number of issuers. The more concentrated a fund's holdings are, the
more likely it is a specific security's poor performance will hurt the fund
significantly.

Turnover Risk: In general, the greater the volume of buying and selling by a
fund (i.e., the higher its "turnover rate"), the greater the impact that bro-
kerage commissions and other transaction costs will have on the fund's perfor-
mance. Any turnover rate in excess of 100% is considered relatively high. Nor-
mally, the Fund's turnover rate will be greater than 100%.

Secondary

Derivatives Risk: Certain derivative instruments (such as options, futures and
swaps) can produce disproportionate gains or losses. They are generally consid-
ered more risky than direct equity investments. Also, in a down market, deriva-
tives could become harder to value or sell at a fair price.

Large/Mid Cap Value Fund
GOAL AND STRATEGY

This is a large/mid cap stock fund with a value emphasis that seeks long-term
growth in capital.

The Fund invests primarily in a diversified mix of common stocks of large- and
mid-sized U.S. companies that are believed to offer favorable prospects for
increasing dividends and growth in capital.

The manager employs a value approach in selecting stocks, using proprietary
equity research to identify stocks having distinct value characteristics based
on industry- specific valuation criteria.

The manager screens the investable universe for stocks with:

 . dividend yields greater than the Russell 1000(R) Value Index, and

 . price/book ratios lower than the Russell 1000(R) Value Index.

The Fund's assets are allocated to industry-specific sub-portfolios that are
managed by each industry analyst. The manager oversees the Fund to maintain
capitalization and industry weights similar to the Russell 1000(R) Value Index.

The Fund normally invests in 100 to 130 stocks, with at least 65% (usually
higher) of its assets in large and mid cap companies. The Fund normally has 5%
or less of its assets in cash and cash equivalents.

The Fund may purchase other types of securities, for example: American Deposi-
tory Receipts (ADRs), and certain derivatives (investments whose value is based
on indices or other securities).

In abnormal market conditions, the Fund may take temporary defensive measures--
such as holding unusually large amounts of cash and cash equivalents--that are
inconsistent with the Fund's primary investment strategy. In taking those mea-
sures, the Fund may not achieve its investment goal.

Mid Cap Blend Fund


GOAL AND STRATEGY

This is a mid cap stock fund that seeks long-term growth in capital.

The Fund invests primarily in a diversified mix of common stocks of mid-sized
U.S. companies that are believed to offer:

 . favorable prospects for increasing dividends and capital appreciation
  (i.e., "value" companies), and

 . above-average potential for growth in revenues and earnings (i.e. "growth"
  companies).

The manager selects stocks using a combination of proprietary equity research
and quantitative tools. Stocks are purchased that are undervalued relative to
the stock's history and have improving earnings growth prospects. The Fund is
managed using risk control techniques that maintain risk and industry charac-
teristics similar to the Russell Mid Cap(TM) Index.

The Fund normally invests in 100 to 150 stocks, with at least 65% (usually
higher) of its assets in mid cap companies. The Fund normally has 5% or less of
its assets in cash and cash equivalents.

The Fund may purchase other types of securities, for example: American Deposi-
tory Receipts (ADRs), and certain derivatives (investments whose value is based
on indices or other securities).

In abnormal market conditions, the Fund may take temporary defensive measures--
such as holding unusually large amounts of cash and cash equivalents--that are

Mid Cap Growth Fund

GOAL AND STRATEGY

This is a non-diversified mid cap stock fund with a growth emphasis that seeks
long-term growth in capital.

The Fund invests primarily in the common stocks of mid-sized U.S. companies
that are believed to offer above-average potential for growth in revenues and
earnings.

The manager selects stocks using proprietary equity research. Stocks are pur-
chased that are expected to have earnings growth potential that may not be rec-
ognized by the investment community. The manager selects stocks without regard
to any pre- defined industry or sector selection criteria.

The manager looks for companies experiencing:

 . above-average growth relative to their peers or the general economy; and

 . positive change due to new product developments, improved regulatory environ-
  ment or a new management team.

The Fund is non-diversified, which means it can take larger positions in a
smaller number of issuers. Based upon its current size and strategy, the Fund
invests in 35 to 75 stocks, with at least 65% of its assets in mid cap compa-
nies. The Fund normally has 15% or less of its assets in cash or cash equiva-
lents.

The Fund may purchase other types of securities, for example: American Deposi-
tory Receipts (ADRs), foreign equity securities of developed countries, and
certain derivatives (investments whose value is based on indices or other secu-
rities).

In abnormal market conditions, the Fund may take temporary defensive measures--
such as holding unusually large amounts of cash and cash equivalents--that are
inconsistent with the Fund's primary investment strategy. In taking those mea-
sures, the Fund may not achieve its investment goal.

PAST PERFORMANCE

The graph shows how the fund's total return has varied from year to year, while
the table shows performance over time (along with a broad-based market index
for reference). This information may help provide an indication of the fund's
risks and potential rewards. All figures assume dividend reinvestment. Past
performance does not indicate future results. The performance figures below do
not reflect the deduction of fees and charges payable under the variable
contracts. Such fees and charges would cause the investment returns under the
contracts to be less than that shown below.

MAIN RISKS

Primary

Small /Mid Cap Stock Risk: The Fund's investment in smaller or mid-sized compa-
nies may be subject to more erratic price movements than investment in large
established companies.

Non-Diversified Fund Risk: The Fund's larger position in individual issuers and
in a smaller number of issuers could produce more volatile performance relative
to more diversified funds. The less diversified a fund's holdings are, the more
likely it is that a specific security's poor performance will hurt the fund
significantly.

Market Risk: The value of the securities in the Fund may go down in response to
overall stock or bond market movements. Markets tend to move in cycles, with
periods of rising prices and periods of falling prices. Stocks tend to go up
and down in value more than bonds. If the Fund's investments are concentrated
in certain sectors, the Fund's performance could be worse than the overall mar-
ket.

Manager Risk: The manager and its strategy may fail to produce the intended
results. The Fund could underperform its peers or lose money if the manager's
investment strategy does not perform as expected.

Investment Category Risk: The returns of the Fund's specific equity investment
category may lag the returns of the overall stock market. For example, the
Fund's "growth" approach carries the risk that in certain markets "growth"
stocks will underperform "value" stocks. Also, the Fund's "mid cap" approach
carries the risk that in certain markets mid cap stocks will underperform small
cap and large cap stocks.

Concentration Risk: The Fund's investment in securities of a smaller number of
issuers could produce more volatile performance relative to funds that invest
in a larger number of issuers. The more concentrated a fund's holdings are, the
more likely it is a specific security's poor performance will hurt the fund
significantly.

Turnover Risk: In general, the greater the volume of buying and selling by a
fund (i.e., the higher its "turnover rate"), the greater the impact that bro-
kerage commissions and other transaction costs will have on the fund's perfor-
mance. Any turnover rate in excess of 100% is considered relatively high. Nor-
mally, the Fund's turnover rate will be greater than 100%.

Secondary

Foreign Risk: The Fund's foreign securities will pose special risks, due to
limited government regulation, lack of public information, economic, political
and social instability and foreign currency rate fluctuations. Factors such as
lack of liquidity, foreign ownership limits and restrictions on removing cur-
rency also pose special risks.

Derivatives Risk: Certain derivative instruments (such as options, futures and
swaps) can produce disproportionate gains or losses. They are generally consid-
ered more risky than direct equity investments. Also, in a down market, deriva-
tives could be- come harder to value or sell at a fair price.

Fundamental Mid Cap Growth Fund


GOAL AND STRATEGY

This is a mid cap stock fund with a growth emphasis that seeks long-term growth
in capital.

The Fund invests primarily in the common stocks of mid-sized U.S. companies
that are believed to offer above-average potential for growth in revenues and
earnings.

The manager selects stocks using both proprietary equity research and external
consensus earnings forecasts. Stocks are purchased that are believed to offer:

 . High rate of sustainable earnings growth of 15% plus,

 . revenue growth generated by operating results (unit volume); and

 .sustainable revenue growth of 10% plus.

The manager looks for companies with:

 . innovative management and strong leadership positions in unique market
  niches;

 . undiscovered and undervalued emerging growth opportunities; and,

 . new products and services.

The Fund's industry exposures are a result of stock selection as opposed to
predetermined allocations.

The Fund normally invests in 60 to 80 stocks, with at least 65% (usually high-
er) of its assets in mid cap companies. The Fund normally has 5% or less of its
assets in cash and cash equivalents.

The Fund may purchase other types of securities, for example: American Deposi-
tory Receipts (ADRs), and certain derivatives (investments whose value is based
on indices or other securities).

In abnormal market conditions, the Fund may take temporary defensive measures--
such as holding unusually large amounts of cash and cash equivalents--that are
inconsistent with the Fund's primary investment strategy. In taking those mea-
sures, the Fund may not achieve its investment goal.

MAIN RISKS

Primary

Small /Mid Cap Stock Risk: The Fund's investment in smaller or mid-sized compa-
nies may be subject to more erratic price movements than investment in large
established companies.

Market Risk: The value of the securities in the Fund may go down in response to
overall stock or bond market movements. Markets tend to move in cycles, with
periods of rising prices and periods of falling prices. Stocks tend to go up
and down in value more than bonds. If the Fund's investments are concentrated
in certain sectors, the Fund's performance could be worse than the overall mar-
ket.

Manager Risk: The manager and its strategy may fail to produce the intended
results. The Fund could underperform its peers or lose money if the manager's
investment strategy does not perform as expected.

Investment Category Risk: The returns of the Fund's specific equity investment
category may lag the returns of the overall stock market. For example, the
Fund's "growth" approach carries the risk that in certain markets "growth"
stocks will underperform "value" stocks. Also, the Fund's "mid cap" approach
carries the risk that mid cap stocks will underperform large cap and small cap
stocks.

Concentration Risk: The Fund's investment in securities of a smaller number of
issuers could produce more volatile performance relative to funds that invest
in a larger number of issuers. The more concentrated a fund's holdings are, the
more likely it is a specific security's poor performance will hurt the fund
significantly.

Turnover Risk: In general, the greater the volume of buying and selling by a
fund (i.e., the higher its "turnover rate"), the greater the impact that bro-
kerage commissions and other transaction costs will have on the fund's perfor-
mance. Any turnover rate in excess of 100% is considered relatively high. Nor-
mally, the Fund's turnover rate will be greater than 100%.

Secondary

Derivatives Risk: Certain derivative instruments (such as options, futures and
swaps) can produce disproportionate gains or losses. They are generally consid-
ered more risky than direct equity investments. Also, in a down market, deriva-
tives could become harder to value or sell at a fair price.

Small/Mid Cap CORE Fund
GOAL AND STRATEGY

This is a small/mid cap stock fund that seeks long-term growth in capital.

The Fund invests primarily in a diversified mix of the common stocks of small
and mid-sized U.S. companies that are believed to offer:

 . favorable prospects for increasing dividends and capital appreciation (i.e.,
  "value" companies); and

 . above-average potential for growth in revenues and earnings (i.e. "growth"
  companies).

The manager selects stocks using a combination of quantitative techniques and
equity research. The manager employs an investment process known as CORE, "Com-
puter Optimized, Research-Enhanced," that employs a proprietary quantitative
model. Stocks are purchased that have strong expected earnings growth and
momentum and better valuation and risk characteristics than the Russell
2500(TM) Index. The Fund is managed using risk control techniques to maintain
risk, style, capitalization and industry characteristics similar to the Russell
2500(TM) Index.

The Fund normally invests in 200 to 600 stocks, with at least 65% (usually
higher) of the Fund's assets in small cap and mid cap companies. The Fund nor-
mally has 10% or less of its assets in cash and cash equivalents.

The Fund may purchase other types of securities, for example: American Deposi-
tory Receipts (ADRs), Standard & Poor's Depository Receipts (SPDRs), and cer-
tain derivatives (investments whose value is based on indices or other securi-
ties).

In abnormal market conditions, the Fund may take temporary defensive measures--
such as holding unusually large amounts of cash and cash equivalents--that are
inconsistent with the Fund's primary investment strategy. In taking those mea-
sures, the Fund may not achieve its investment goal.

category may lag the returns of the overall stock market. For example, the
Fund's "small/mid cap" approach carries the risk that in certain markets
small/mid cap stocks will underperform large cap stocks.

Turnover Risk: In general, the greater the volume of buying and selling by a
fund (i.e., the higher its "turnover rate"), the greater the impact that bro-
kerage commissions and other transaction costs will have on the fund's perfor-
mance. Any turnover rate in excess of 100% is considered relatively high. The
Fund had unusually high turnover in 1999 and is expected to experience similar
turnover in 2000. This higher than expected turnover is due to (i) the rela-
tively small size of the Fund, which magnifies the effect of contributions and
redemptions, and (ii) the high volatility of the market, which in 1999 resulted
in the subadviser implementing procedures to reduce the Fund's tracking risk.
Normally, the Fund's turnover rate will be less than 100%.

Secondary

Derivatives Risk: Certain derivative instruments (such as options, futures and
swaps) can produce disproportionate gains or losses. They are generally consid-
ered more risky than direct equity investments. Also, in a down market, deriva-
tives could become harder to value or sell at a fair price.

Small/Mid Cap Value Fund
GOAL AND STRATEGY

This is a small/mid cap stock fund with a value emphasis that seeks long-term
growth in capital.

The Fund invests primarily in a diversified mix of the common stocks of small
and mid-sized U.S. companies that are believed to offer favorable prospects for
capital appreciation.

The manager selects stocks using a combination of proprietary quantitative
screening tools and fundamental equity research. The manager selects stocks
that have:

 .  attractive valuation characteristics, using measures such as low price-
   /earnings and price/book ratios;

 .  strong business health, as measured by overall efficiency and profitability
   (return on assets and/or equity); and

 .  business momentum, defined as a catalyst that the manager believes will
   trigger a near-term price increase.

The Fund is broadly diversified by sector. The Fund normally invests in 70 to
150 stocks, with at least 65% (usually higher) of its assets in small and mid
cap companies. The Fund normally has 5% or less of its assets in cash and cash
equivalents.

The Fund may purchase other types of securities, for example: American Deposi-
tory Receipts (ADRs), and certain derivatives (investments whose value is based
on indices or other securities).

In abnormal market conditions, the Fund may take temporary defensive measures--
such as holding unusually large amounts of cash and cash equivalents--that are
inconsistent with the Fund's primary investment strategy. In taking those mea-
sures, the Fund may not achieve its investment goal.

Small/Mid Cap Growth Fund

GOAL AND STRATEGY

This is a small/mid cap stock fund with a growth emphasis that seeks long-term
growth in capital.

The Fund invests primarily in the common stocks of small and mid-sized U.S.
companies that are believed to offer above-average potential for growth in rev-
enues and earnings.

The manager selects stocks using a combination of proprietary quantitative and
qualitative equity research. Quantitative screening seeks to identify a group
of high-quality companies with above-average growth characteristics relative to
industry peers. Equity research seeks to identify
individual companies from that group with a higher potential for long term
earnings growth and capital appreciation.

The manager buys companies that seem attractive based on a combination of cri-
teria, among others:

 . Superior historical earnings growth

 . Prospects for above-average growth

 . Attractive valuations

 . Strong market positions

 . Favorable new products

 . Superior management

The Fund is broadly diversified by industry sector. The Fund normally invests
in 60 to 100 stocks, with at least 65% (usually higher) of its assets in small
and mid cap companies. The Fund normally has 5% or less of its assets in cash
and cash equivalents.

The Fund may purchase other types of securities, for example: American Deposi-
tory Receipts (ADRs), and certain derivatives (investments whose value is based
on indices or other securities).

In abnormal market conditions, the Fund may take temporary defensive measures--
such as holding unusually large amounts of cash and cash equivalents--that are
inconsistent with the Fund's primary investment strategy. In taking those mea-
sures, the Fund may not achieve its investment goal.

PAST PERFORMANCE

The graph shows how the Fund's total return has varied from year to year, while
the table shows performance over time (along with a broad-based market index
for reference). This information may help provide an indication of the Fund's
risks and potential rewards. All figures assume dividend reinvestment. Past
performance does not indicate future results. The performance figures below do
not reflect the deduction of fees and charges payable under the variable con-
tracts. Such fees and charges would cause the investment returns under the con-
tracts to be less than that shown below.

MAIN RISKS

Primary

Small/Mid Cap Stock Risk: The Fund's investment in smaller or mid-sized compa-
nies may be subject to more erratic price movements than investment in large
established companies.

Market Risk: The value of the securities in the Fund may go down in response to
overall stock or bond market movements. Markets tend to move in cycles, with
periods of rising prices and periods of falling prices. Stocks tend to go up
and down in value more than bonds. If the Fund's investments are concentrated
in certain sectors, the Fund's performance could be worse than the overall mar-
ket.

Manager Risk: The manager and its strategy may fail to produce the intended
results. The Fund could underperform its peers or lose money if the manager's
investment strategy does not perform as expected.

Investment Category Risk: The returns of the Fund's specific equity investment
category may lag the returns of the overall stock market. For example, the
Fund's "growth" approach carries the risk that in certain markets "growth"
stocks will underperform "value" stocks. Also, the Fund's "small/mid cap"
approach carries the risk that in certain markets small/mid cap stocks will
underperform large cap stocks.

Concentration Risk: The Fund's investment in securities of a smaller number of
issuers could produce more volatile performance relative to funds that invest
in a larger number of issuers. The more concentrated a fund's holdings are, the
more likely it is a specific security's poor performance will hurt the fund
significantly.

Turnover Risk: In general, the greater the volume of buying and selling by a
fund (i.e., the higher its "turnover rate"), the greater the impact that bro-
kerage commissions and other transaction costs will have on the fund's perfor-
mance. Any turnover rate in excess of 100% is considered relatively high. The
Fund had a high turnover rate in 1999 because of a change in management and a
change in the Fund's investment strategy. These changes required a restructur-
ing of the Fund's investments. In future years, the Fund's turnover rate will
normally be less than 100%.

Small Cap Growth Fund
GOAL AND STRATEGY

This is a small cap stock fund with a growth emphasis that seeks long-term
growth in capital.

The Fund invests primarily in a diversified mix of the common stocks of small
U.S. companies that are believed to offer above-average potential for growth in
revenues and earnings.

The manager selects stocks using proprietary equity research. Stocks are pur-
chased that are expected to have rapid earnings growth that is not yet widely
recognized by the investment community.

The manager looks for companies with:

 . demonstrated annual 20% earnings growth over 3 years and/or similar future
  growth expectations,

 . dominant market niche or poised to become market leaders, and

 . high quality senior management with coherent business strategies.

The Fund is highly diversified by sector and number of individual stocks. The
Fund's sector weightings are broadly diversified and managed relative to those
of the Russell 2000(R) Growth Index. The Fund normally invests in 150 to 220
stocks, with at least 65% (usually higher) of its assets in small cap compa-
nies. The Fund normally has 5% or less of its assets in cash and cash equiva-
lents.

The Fund may purchase other types of securities, for example: American Deposi-
tory Receipts (ADRs), and certain derivatives (investments whose value is based
on indices or other securities).

In abnormal market conditions, the Fund may take temporary defensive measures--
such as holding unusually large amounts of cash and cash equivalents--that are
inconsistent with the Fund's primary investment strategy. In taking those mea-
sures, the Fund may not achieve its investment goal.

ered more risky than direct equity investments. Also, in a down market, deriva-
tives could become harder to value or sell at a fair price.

Global Balanced Fund
(Formerly International Balanced Fund)

GOAL AND STRATEGY

This is a non-diversified global balanced stock and bond fund that seeks long-
term growth in income and capital.

The Fund invests primarily in a mix of:

 . U.S. and foreign common stocks of large companies within developed markets;
  and

 . U.S. and foreign investment grade bonds of issuers within developed markets
  with maturities generally greater than 12 months.

The manager makes ongoing decisions about the mix between stocks and bonds. The
manager has a target mix of 65% stocks and 35% bonds, but actively manages the
mix within (+/-) 10 percentage points of the target mix.

The Fund invests:

 . in at least 3 different countries, but normally invests in 10 to 20 coun-
  tries; and

 . no more than 10% of its assets in emerging market stocks and bonds.

The manager selects stocks and bonds using fundamental value analysis to iden-
tify fairly priced investments with long-term sustainable cash flows. The man-
ager determines fundamental value by focusing on:

 . current market prices relative to fundamental values;

 . broad-based indices for stocks, bonds, and markets; and

 . economic variables such as productivity, inflation and global competitive-
  ness.

The Fund is non-diversified, which means that it can take larger positions in a
smaller number of issuers. However, the Fund normally invests in 125 to 250
stocks within the stock portion. The Fund normally has 10% or less of its
assets in cash and cash equivalents.

The Fund may purchase other types of securities, for example: American Deposi-
tory Receipts (ADRs), Global Depository Receipts (GDRs), European Depository
Receipts (EDRs), high yield bonds, and certain derivatives (investments whose
value is based on indices or other securities).

The manager actively uses derivatives, such as futures and forwards, to manage
the Fund's average maturity relative to the Salomon Brothers World Government
Bond Index Unhedged and to implement foreign currency strategies. Currency man-
agement strategies are primarily used for hedging purposes and to protect
against anticipated changes in foreign currency exchange rates.

In abnormal market conditions, the Fund may take temporary defensive measures--
such as holding unusually large amounts of cash and cash equivalents--that are
inconsistent with the Fund's primary investment strategy. In taking those mea-
sures, the Fund may not achieve its investment goal.

MAIN RISKS

Primary

Foreign Risk: The Fund's foreign securities will pose special risks, due to
limited government regulation, lack of public information, economic, political
and social instability and foreign currency rate fluctuations. Factors such as
lack of liquidity, foreign ownership limits and restrictions on removing cur-
rency also pose special risks. All foreign securities have some degree of for-
eign risk. However, to the extent the Fund invests in emerging market coun-
tries, it will have a significantly higher degree of foreign risk than if it
invested exclusively in developed or newly-industrialized countries.

Non-Diversified Fund Risk: The Fund's larger position in foreign government
securities could produce more volatile performance relative to funds with
smaller positions. The less diversified a fund's holdings are, the more likely
it is that a specific security's poor performance will hurt the fund signifi-
cantly.

Market Risk: The value of the securities in the Fund may go down in response to
overall stock or bond market movements. Markets tend to move in cycles, with
periods of rising prices and periods of falling prices. Stocks tend to go up
and down in value more than bonds. If the Fund's investments are concentrated
in certain sectors, the Fund's performance could be worse than the overall mar-
ket.
Manager Risk: The manager and its strategy may fail to produce the intended
results. The Fund could underperform its peers or lose money if the manager's
investment strategy does not perform as expected.

Investment Category Risk: The returns of the Fund's specific equity investment
category may lag the returns of the overall stock market. For example, the
Fund's "value" approach carries the risk that in certain markets "value" stocks
will underperform "growth" stocks. Also, the Fund's "large/mid cap" approach
carries the risk that large/mid cap stocks will underperform small cap stocks.

Market Allocation Risk: The allocation of the Fund's assets between the major
asset classes (i.e., stocks and bonds) may (1) reduce the Fund's holdings in a
class whose value then increases unexpectedly, or (2) increase the Fund's hold-
ings in a class just prior to its experiencing a loss of value.

Interest Rate Risk: When interest rates rise, the Fund's bond yields will gen-
erally rise and the Fund's bond prices will generally fall. When interest rates
fall, the reverse will generally occur. The longer the average remaining matu-
rity of bonds held by the Fund, the more sensitive the Fund is to interest rate
risk. This Fund has more interest rate risk than a short-term bond fund, but
less interest rate risk than a long-term bond fund.
Credit Risk: An issuer of a bond held by the Fund may default on its obligation
to pay interest and repay principal. Also, the credit rating of a bond held by
the fund may be downgraded. In either case, the value of the bond held by the
Trust would fall. All bonds have some credit risk, but in general lower-rated
bonds have higher credit risk.

Turnover Risk. In general, the greater the volume of buying and selling by a
fund (i.e., the higher its "turnover rate"), the greater the impact that bro-
kerage commissions and other transaction costs will have on the fund's perfor-
mance. Any turnover rate in excess of 100% is considered relatively high. Nor-
mally, the Fund's turnover rate will be greater than 100%.

Secondary

Derivatives Risk: Certain derivative instruments (such as options, futures and
swaps) can produce disproportionate gains or losses. They are generally consid-
ered more risky than direct equity investments. Also, in a down market, deriva-
tives could become harder to value or sell at a fair price.

High Yield Bond Risk. Junk bonds, defined as bond securities rated below BBB-
/Baa3, may be subject to more volatile or erratic price movements due to
investor sentiment. In a down market, these high yield securities become harder
to value or to sell at a fair price.

International Equity Fund
GOAL AND STRATEGY

This is an international stock fund that seeks long-term growth in capital.

The Fund primarily invests in a diversified mix of common stocks of large
established and medium-sized foreign companies located primarily in developed
countries outside of the U.S.

The manager selects stocks using proprietary equity research that identifies
companies having:

 . strong market positions within their industry,

 . management with a history of excellence focusing on core businesses,

 . above average return on capital within their industry, and

 . demonstrated ability to create long-term shareholder value.

The manager determines the allocation among regions and countries using a com-
bination of qualitative and quantitative inputs, including:

 . quantitative models to rank the relative attractiveness of each
  country/region based on valuation, credit risk and momentum, and

 . qualitative assessment of regional portfolio managers to adjust model
  results.

The Fund's industry exposures are largely the result of stock selection,
although the Fund maintains broad industry representation. The Fund is managed
using risk control techniques that maintain overall regional diversification.
The Fund may either (i) employ foreign currency hedging techniques in order to
maintain a neutral currency position to the benchmark or (ii) maintain the cur-
rency exposure of the underlying equity investments.

The Fund invests in at least 3 different countries, but normally invests in 10
to 20 countries.

The Fund will invest no more than 10% of its assets in emerging market stocks.

The Fund normally invests in 120 to 180 stocks and normally has 10% or less of
its assets in cash and cash equivalents.

The Fund also may purchase other types of securities, for example: American
Depository Receipts (ADRs), Global Depository Receipts (GDRs), European Deposi-
tory Receipts (EDRs), and certain derivatives (investments whose value is based
on indices or other securities).

In abnormal market conditions, the Fund may take temporary defensive measures--
such as holding unusually large amounts of cash and cash equivalents--that are
inconsistent with the Fund's primary investment strategy. In taking those mea-
sures, the Fund may not achieve its investment goal.

MAIN RISKS

Primary

Foreign Risk: The Fund's foreign securities will pose special risks, due to
limited government regulation, lack of public information, economic, political
and social instability and foreign currency rate fluctuations. Factors such as
lack of liquidity, foreign ownership limits and restrictions on removing cur-
rency also pose special risks. All foreign securities have some degree of for-
eign risk. However, to the extent the Fund invests in emerging market coun-
tries, it will have a significantly higher degree of foreign risk than if it
invested exclusively in developed or newly-industrialized countries.

Market Risk: The value of the securities in the Fund may go down in response to
overall stock or bond market movements. Markets tend to move in cycles, with
periods of rising prices and periods of falling prices. Stocks tend to go up
and down in value more than bonds. If the Fund's investments are concentrated
in certain sectors, the Fund's performance could be worse than the overall mar-
ket.

Manager Risk: The manager and its strategy may fail to produce the intended
results. The Fund could underperform its peers or lose money if the manager's
investment strategy does not perform as expected.

Secondary

Derivatives Risk: Certain derivative instruments (such as options, futures and
swaps) can produce disproportionate gains or losses. They are generally consid-
ered more risky than direct equity investments. Also, in a down market, deriva-
tives could become harder to value or sell at a fair price.

Short-Term Bond Fund

GOAL AND STRATEGY

This is a short-term bond fund that seeks high income consistent with low share
price fluctuation.

The Fund primarily invests in a diversified mix of short-term and intermediate-
term investment grade debt securities including:

 . U.S. Treasury and Agency securities;

 . U.S. corporate bonds;

 . foreign corporate bonds of companies in developed countries (if dollar-
  denominated);

 . foreign government and agency securities of developed countries (if dollar
  denominated); and

 . mortgage-and asset-backed securities.

The manager selects bonds using a combination of proprietary research and quan-
titative tools. Bonds are purchased that are attractively priced and that pro-
vide cheap, predictable cash flows.

The Fund normally invests:

 . mostly in corporate bonds;

 . no more than 15% of its assets in high yield bonds; and

 . no more than 25% of its assets in foreign debt securities.

The Fund normally has:

 . an average maturity between one and three and a half years;

 . an average credit quality rating of "A" or higher; and

 . 10% or less of its assets in cash and cash equivalents.

The Fund only invests in securities that are rated at least BB- or Ba3 at time
of purchase.

The Fund may purchase other types of securities, for example: certain deriva-
tives (investments whose value is based on indexes or other securities).

In abnormal market conditions, the Fund may take temporary defensive measures--
such as holding unusually large amounts of cash and cash equivalents--that are
inconsistent with the Fund's primary investment strategy. In taking those mea-
sures, the Fund may not achieve its investment goal.

MAIN RISKS

Primary

Market Risk: The value of the securities in the Fund may go down in response
to overall stock or bond market movements. Markets tend to move in cycles,
with periods of rising prices and periods of falling prices. Stocks tend to go
up and down in value more than bonds. If the Fund's investments are concen-
trated in certain sectors, the Fund's performance could be worse than the
overall market.

Manager Risk: The manager and its strategy may fail to produce the intended
results. The Fund could underperform its peers or lose money if the manager's
investment strategy does not perform as expected.

Interest Rate Risk: When interest rates rise, the Fund's bond yields will gen-
erally rise and the Fund's bond prices will generally fall. When interest
rates fall, the reverse will generally occur. The longer the average remaining
maturity of bonds held by the Fund, the more sensitive the Fund is to interest
rate risk. This Fund has less interest rate risk than an intermediate-term or
long-term bond fund.
Credit Risk: An issuer of a bond held by the Fund may default on its obliga-
tion to pay interest and repay principal. Also, the credit rating of a bond
held by the fund may be downgraded. In either case, the value of the bond held
by the Trust would fall. All bonds have some credit risk, but in general low-
er-rated bonds have higher credit risk.

Concentration Risk: The Fund's investment in securities of a smaller number of
issuers could produce more volatile performance relative to funds that invest
in a larger number of issuers. The more concentrated a fund's holdings are,
the more likely it is a specific security's poor performance will hurt the
fund significantly.

Turnover Risk: In general, the greater the volume of buying and selling by a
fund (i.e., the higher its "turnover rate"), the greater the impact that bro-
kerage commissions and other transaction costs will have on the fund's perfor-
mance. Any turnover rate in excess of 100% is considered relatively high. Nor-
mally, the Fund's turnover rate will be greater than 100%.
Secondary

Foreign Risk: The Fund's foreign securities will pose special risks, due to
limited government regulation, lack of public information, and economic,
political and social instability. Factors such as lack of liquidity, foreign
ownership limits and restrictions on removing currency also pose special
risks.

Derivatives Risk: Certain derivative instruments (such as options, futures and
swaps) can produce disproportionate gains or losses. They are generally con-
sidered more risky than direct equity investments. Also, in a down market,
derivatives could become harder to value or sell at a fair price.

High Yield Bond Risk: Junk bonds, defined as bond securities rated below BBB-
/Baa3, may be subject to more volatile or erratic price movements due to
investor sentiment. In a down market, these high yield securities become
harder to value or to sell at a fair price.

Prepayment / Call Risk: The Fund's share price or yield could be hurt if
interest rate movements cause the Fund's mortgage-related and callable securi-
ties to be paid off substantially earlier than expected.

Bond Index Fund

GOAL AND STRATEGY

This is a bond fund that seeks to track the performance of the Lehman Brothers
Government / Corporate Bond Index.

The manager employs a passive management strategy using quantitative techniques
to select individual securities that provide a representative sample of the
securities in the Index.

If the Fund reaches approximately $50 million in total assets, the manager will
seek to match the performance of the Lehman Brothers Aggregate Bond Index, a
broader market index that also includes mortgage-backed and asset-backed secu-
rities.

Both of these Indexes consist of dollar-denominated investment grade securities
with maturities greater than one year and outstanding par values of at least
$150 million issued primarily by:

 . the U.S. Treasury and U.S. government agencies and instrumentalities;

 . foreign governments and agencies; and

 . U.S. and foreign corporations.

The manager selects securities to match, as closely as practical, the Index's
duration, cash flow, sector, credit quality, callability, and other key perfor-
mance characteristics. The Fund may hold some cash and cash equivalents, but is
normally fully invested.
The Index composition may change from time to time. The manager may keep secu-
rities that no longer meet the Index criteria as long as:

 . such "ineligible" securities plus cash and money market instruments are less
  than 20% of the Fund's assets; and

 . high yield securities are less than 5% of the Fund's assets.

MAIN RISKS

Primary

Index Management Risk:  Certain factors such as the following may cause the
Fund to track the Index less closely:

 . The securities selected by the manager may not be fully representative of the
  Index.

 . Transaction expenses of the Fund may result in the Fund's performance being
  different than that of the Index.

 . The size and timing of the Fund's cash flows may result in the Fund's perfor-
  mance being different than that of the Index.

Also, index funds like this one will have more difficulty in taking defensive
positions in abnormal market conditions.

Market Risk: The value of the securities in the Fund may go down in response to
overall stock or bond market movements. Markets tend to move in cycles, with
periods of rising prices and periods of falling prices. Stocks tend to go up
and down in value more than bonds. If the Fund's investments are concentrated
in certain sectors, the Fund's performance could be worse than the overall mar-
ket.

Manager Risk: The manager and its strategy may fail to produce the intended
results. The Fund could underperform its peers or lose money if the manager's
investment strategy does not perform as expected.

Interest Rate Risk: When interest rates rise, the Fund's bond yields will gen-
erally rise and the Fund's bond prices will generally fall. When interest rates
fall, the reverse will generally occur. The longer the average remaining matu-
rity of bonds held by the Fund, the more sensitive the Fund is to interest rate
risk. This Fund has more interest rate risk than a short-term bond fund, but
less interest rate risk than a long-term bond fund.

Credit Risk: An issuer of a bond held by the Fund may default on its obligation
to pay interest and repay principal. Also, the credit rating of a bond held by
the fund may be downgraded. In either case, the value of the bond held by the
Trust would fall. All bonds have some credit risk, but in general lower-rated
bonds have higher credit risk.

Secondary

Foreign Risk: The Fund's foreign securities will pose special risks, due to
limited government regulation, lack of public information, and economic, polit-
ical and social instability. Factors such as lack of liquidity, foreign owner-
ship limits and restrictions on removing currency also pose special risks. All
foreign securities have some degree of foreign risk. However, to the extent the
Fund invests in emerging market countries, it will have a significantly higher
degree of foreign risk than if it invested exclusively in developed or newly-
industrialized countries.

High Yield Bond Fund

GOAL AND STRATEGY

This is a high yield bond fund that seeks high income and growth in capital.

The Fund invests primarily in a diversified mix of high yield debt securities,
commonly referred to as "junk bonds" (rated BB+/Ba1 or lower and their unrated
equivalents), including:

 . corporate bonds, both U.S. and foreign (if dollar-denominated);

 . foreign government and agency securities (if dollar-denominated);

 . preferred stocks; and

 . convertible securities (convertible into common stocks or other equity inter-
  ests).

The manager will invest no more than 15% of the Fund's assets in emerging mar-
ket countries (with below investment-grade sovereign debt). The Fund normally
has 10% or less of its assets in cash and cash equivalents.

The manager seeks to purchase bonds with stable or improving credit quality
before the market widely perceives the improvement. Purchase and sale decisions
are primarily based upon the investment merits of the particular security.

The manager selects bonds using proprietary research, including:

 . quantitative analysis of historical financial data;

 . qualitative analysis of a company's future prospects; and

 . economic and industry analysis.

The Fund's average maturity depends on security selection decisions rather than
interest rate decisions.

The Fund may purchase other types of securities, for example: equity securi-
ties, high quality debt securities (short-term and otherwise), certain deriva-
tives (investments whose value is based on indices or other securities), and
debt securities denominated in foreign currencies.

In abnormal market conditions, the Fund may take temporary defensive measures--
such as holding unusually large amounts of cash and cash equivalents--that are
inconsistent with the Fund's primary investment strategy. In taking those mea-
sures, the Fund may not achieve its investment goal.

PAST PERFORMANCE

The graph will show how the fund's total return varies from year to year, while
the table will show performance over time (along with a broad-based market
index for reference). This information may help provide an indication of the
fund's risks and potential rewards. All figures assume dividend reinvestment.
Past performance does not indicate future results. The performance figures
below do not reflect the deduction of fees and charges payable under the
variable contracts. Such fees and charges would cause the investment returns
under the contracts to be less than that shown below.

MAIN RISKS

Primary

High Yield Bond Risk: High yield or junk bonds, defined as bond securities
rated below BBB-/Baa3, may be subject to more volatile or erratic price move-
ments due to investor sentiment. In a down market, these high yield securities
may become harder to value or to sell at a fair price.

Market Risk: The value of the securities in the Fund may go down in response to
overall stock or bond market movements. Markets tend to move in cycles, with
periods of rising prices and periods of falling prices. Stocks tend to go up
and down in value more than bonds. If the Fund's investments are concentrated
in certain sectors, the Fund's performance could be worse than the overall mar-
ket.

Manager Risk: The manager and its strategy may fail to produce the intended
results. The Fund could underperform its peers or lose money if the manager's
investment strategy does not perform as expected.
Interest Rate Risk: When interest rates rise, the Fund's bond yields will gen-
erally rise and the Fund's bond prices will generally fall. When interest rates
fall, the reverse will generally occur. The longer the average remaining matu-
rity of bonds held by the Fund, the more sensitive the Fund is to interest rate
risk. This Fund has more interest rate risk than a short-term bond fund, but
less interest rate risk than a long-term bond fund.

Credit Risk: An issuer of a bond held by the Fund may default on its obligation
to pay interest and repay principal. Also, the credit rating of a bond held by
the fund may be downgraded. In either case, the value of the bond held by the
Fund would fall. All bonds have some credit risk, but in general lower-rated
bonds have higher credit risk.

Secondary

Foreign Risk: The Fund's foreign securities will pose special risks, due to
limited government regulation, lack of public information, and economic, polit-
ical and social instability. Factors such as lack of liquidity, foreign owner-
ship limits and restrictions on removing currency also pose special risks. All
foreign securities have some degree of foreign risk. However, to the extent the
Fund invests in emerging market countries, it will have a significantly higher
degree of foreign risk than if it invested exclusively in developed or newly-
industrialized countries.

Derivatives Risk: Certain derivative instruments (such as options, futures and
swaps) can produce disproportionate gains or losses. They are generally consid-
ered more risky than direct equity investments. Also, in a down market, deriva-
tives could become harder to value or sell at a fair price.

Prepayment/Call Risk: The Fund's share price or yield could be hurt if interest
rate movements cause the Fund's mortgage-related and callable securities to be
paid off substantially earlier than expected.

Your Account

Investments in shares of the funds

Each fund sells its shares directly to separate accounts of John Hancock,
JHVLICO and IPL to fund variable contracts. Each fund also buys back its shares
on redemption by the separate accounts.

Under the variable contracts, a separate account buys or redeems a fund's
shares based on:

 . instructions by you and other contractowners to invest or receive back monies
  under a contract (such as making a premium payment or surrendering a con-
  tract), and

 . the operation of a contract (such as deduction of fees and charges).

The Trust, as law permits, may:

 . refuse a buy order if the adviser believes it would disrupt management,

 . suspend a fund's offer of shares, or

 . suspend a fund's redemption obligation or postpone a fund's payment of
  redemption proceeds for more than seven days.

Share price

Each fund sells and buys back its shares at the net asset value per share
("NAV") next computed after receipt by a separate account of a contractowner's
instructions.

Each fund calculates its NAV:

 . by dividing its net assets by the number of its outstanding shares,

 . once daily as of the close of regular trading on the New York Stock Exchange
  (generally at 4 p.m. New York time) on each day the Exchange is open.

Certain funds may hold securities primarily listed on foreign exchanges that
trade on weekends or other days when the Trust does not calculate NAV. Conse-
quently, NAV may change on days when contractowners will not be able to
instruct a separate account to buy or redeem fund shares.

Valuation

Each of the funds values securities based on:

 . market quotations,

 . amortized cost,

 . valuations of independent pricing services, or

 . fair value determined in accordance with procedures approved by the Trust's
  trustees.

A fund may value securities at fair value where, for example:

 . market quotations are not readily available, or

 . the value of securities has been materially affected after the closing of a
  foreign market.

Conflicts

The Trust's trustees monitor for possible material irreconcilable conflicts
among separate accounts buying shares of the funds. The Trust's net asset value
could decrease, if the Trust had to sell investment securities to pay redemp-
tion proceeds to a separate account withdrawing because of a conflict.

The adviser pays subadvisory fees out of its own assets. No fund pays a fee to
its subadviser. The adviser has agreed to limit each fund's annual expenses
(excluding advisory fees and certain other expenses such as brokerage and tax-
es) to not more than .10 percent of the fund's average daily net assets.


Dividends

Each fund automatically reinvests its dividends and distributions in additional
shares of the fund at NAV.

Each fund declares and pays dividends monthly.

Funds generally declare capital gains distributions annually.

Taxes

Each fund must meet investment diversification and other requirements under the
Internal Revenue Code, in order to:

 . avoid federal income tax and excise tax, and

 . assure the tax-deferred treatment of variable contracts under the Code.

You should read the prospectus for your variable contract for the federal
income tax consequences for contractowners, including the consequences of a
fund's failure to meet Code requirements.

APPENDIX

Additional Performance Information

The "Past Performance" information shown earlier in this prospectus for certain
of the Funds may not be sufficient for you to make a complete assessment of the
risks and potential rewards of investing in those Funds. The Aggressive Bal-
anced Fund, the Large Cap Value CORE Fund, the Large Cap Aggressive Growth
Fund, the Large/Mid Cap Value Fund, the Mid Cap Blend Fund, and the Small/Mid
Cap Value Fund only began operations on August 31, 1999. The Small/Mid Cap CORE
Fund, the Bond Index Fund, and the High Yield Bond Fund only began operations
on May 1, 1998. Finally, the Global Balanced Fund and the Small/Mid Cap Growth
Fund each implemented a significant change in strategy as of May 1, 2000, and
May 1, 1999, respectively.

Since each of these Funds has at best a very limited period of relevant perfor-
mance history, we have set forth below information for certain similar accounts
that are managed by the Funds' respective subadvisers. Each grouping of such
accounts is referred to as a "composite." In the case of each account included
in a composite, the total management fees and other operating expenses of the
Fund (based upon management fee schedules and allocation rules currently in
effect) have been substituted for the actual fees and expenses (other than bro-
kerage and other transaction expenses) of the account. Also, except as specifi-
cally noted below, each composite includes all of the investment company and
other accounts of the subadviser that satisfy the following requirements:

 . they have been managed with investment objectives, policies, and strategies
  substantially similar to those used in managing the Fund, and

 . they are of sufficient size that their performance would be considered rele-
  vant to the owner of a variable contract investing in that Fund.

Some of the accounts in the composites were not registered investment companies
and, therefore, were not subject to federal income tax and other legal require-
ments applicable to such companies. Had such accounts been subject to such
requirements, their performance could have been adversely affected. The perfor-
mance figures in this Appendix do not reflect the deduction of fees and charges
payable under the variable contracts. Such fees and charges would cause the
investment returns under the contacts to be less than that shown below.
The graphs below show how the composite's total return has varied from year to
year, while the tables show performance over time (along with a broad-based
index for reference). All figures assume dividend reinvestment. Past perfor-
mance does not indicate future results.

Aggresive Balanced Composite (Corresponding to Aggressive Balanced Fund)

The Aggressive Balanced Composite represents the following blend of two other
composites: 75% Diversified Core Equity Composite and 25% Active Core Bond Com-
posite. Each composite is asset-weighted and contains all fully discretionary
accounts managed using a substantially similar investment strategy. As of
December 31, 1999, the Diversified Core Equity Composite included 97 accounts
with total assets of $8.9 billion, and the Active Core Bond Composite included
9 accounts with total assets of $1.1 billion.

Overview

- --------------------------------------------------------------------------------
FUND INFORMATION KEY
Concise fund-by-fund descriptions begin on page 6. Each description provides
the following information:

Goal and Strategy The fund's particular investment goals and the principal
strategies it intends to use in pursuing those goals.

Subadviser/Manager The firm and individual(s) providing investment management
services to the fund.

Past Performance The fund's total return, measured year-by-year and over time.

Main Risks The significant risk factors associated with the fund. The risks are
categorized as "Primary" or "Secondary". The Primary Risks are considered major
factors in the fund's performance and are described first. The Secondary Risks
are not considered major factors in the fund's performance because the fund
would not normally commit a large portion of its assets to the investments
involved. However, the Secondary Risks are of such a nature that they could
significantly affect the fund's performance, even if the investments are held
in relatively small amounts.

Financial Highlights The fund's operating performance per share, measured year-
by-year.
THE FUNDS
The Trust offers investment choices, or funds, for the variable annuity and
variable life insurance contracts ("variable contracts") of:

 . John Hancock Life Insurance Company ("John Hancock"),

 . John Hancock Variable Life Insurance Company ("JHVLICO"), and

 . Investors Partner Life Insurance Company and its subsidiaries ("IPL").

In some variable contract forms, the Trust is referred to as the "Fund" or "Se-
ries Fund" and the investment choices are referred to as "Portfolios."

RISKS OF FUNDS
These funds, like all mutual funds, are not bank deposits. They are not insured
or guaranteed by the FDIC or any other government agency. You could lose money
by investing in these funds. So, be sure to read all risk disclosure carefully
before investing.

MANAGEMENT
John Hancock is the investment adviser of each fund. John Hancock is a Massa-
chusetts stock life insurance company. On February 1, 2000, John Hancock
changed its form of organization and its name. Prior to that date, it was John
Hancock Mutual Life Insurance Company, a mutual life insurance company that was
chartered in 1862. At the end of 1999, John Hancock managed approximately $127
billion, of which it owned over
$71 billion. Most of the funds have subadvisers.

Your Investment Choices

- -------------------------------------------------------------------------------
The Trust offers a number of investment choices, or funds, to suit a variety
of objectives under variable contracts. There are 23 funds available under
your variable contract. Each fund has its own strategy and its own risk/reward
profile.The funds can be broadly categorized as equity funds, balanced funds,
bond funds, and international/global funds. Within these broad categories, the
funds can be further categorized as follows:

Equity Funds
Equity funds can be categorized in two ways--by capitalization and by invest-
ment style.

Capitalization             Equity funds can be categorized by market capital-
                           ization, which is defined as the market value of
                           all shares of a company's stock. The following def-
                           initions for large, mid and small cap are based
                           upon statistics at year-end 1999, but are adjusted
                           periodically with broad equity market movements as
                           represented by the Russell 3000(R) Index or other
                           widely-recognized source of market capitalization
                           data. Adjustments are typically made on a quarterly
                           basis, but in extraordinary circumstances may be
                           made as frequently as monthly.

                           Large Cap Funds:

 . Growth & Income Fund     These funds invest in large, well-established com-
                           panies that typically are very actively traded and
 . Equity Index Fund        provide more stable investment returns over time.
                           Large cap companies represent the 300 largest
 . Large Cap Value Fund     stocks in the Russell 3000(R) Index. Each of those
                           companies has a market capitalization greater than
 . Large Cap Growth Fund    $7.9 billion as of the end of 1999. Large cap funds
                           are appropriate for investors who want the least
                           volatile investment returns within the overall
                           equity markets.

                           Mid Cap Funds:

 . Mid Cap Value Fund       These funds invest in medium-sized, less estab-
                           lished companies that are less actively traded and
 . Mid Cap Growth Fund      provide more share price volatility over time than
                           large cap stocks. Mid cap companies represent the
 . Small/Mid Cap CORE Fund  250th to 1000th largest stocks in the Russell
                           3000(R) Index. Each of those companies has a market
 . Small Mid/Cap Growth     capitalization between $1.4 billion and $9.7 bil-
  Fund                     lion as of the end of 1999. Mid cap funds are
                           appropriate for investors who are willing to accept
 . Real Estate Equity Fund  more volatile investment returns within the overall
                           equity markets with the potential reward of higher
                           long-term returns.

                           Small Cap Funds:

 . Small Cap Value Fund     These funds invest in small newly established com-
                           panies that are less actively traded and have a
 . Small Cap Growth Fund    high level of share price volatility over time.
                           Small cap companies represent the 2000 smallest
                           stocks in the Russell 3000(R) Index. Each of those
                           companies has a market capitalization of less than
                           $1.4 billion as of the end of 1999. Small cap funds
                           are appropriate for investors who are willing to
                           accept the most volatile investment returns within
                           the overall equity markets for the potential reward
                           of higher long-term returns.

Investment Style
                           Value Funds:

 . Large Cap Value Fund     Value funds invest in companies that are attrac-
                           tively priced, considering their asset and earnings
 . Mid Cap Value Fund       history. These stocks typically pay above average
                           dividends and have low stock prices relative to
 . Small Cap Value Fund     measures of earnings and book value. Value funds
                           are appropriate for investors who want some divi-
 . Real Estate Equity Fund  dend income and the potential for capital gains,
                           but are less tolerant of share-price fluctuations.


                                                                              3

                           Growth Funds:

 . Large Cap Growth Fund    Growth funds invest in companies believed to have
                           above-average prospects for capital growth due to
 . Mid Cap Growth Fund      their strong earnings and revenue potential. Growth
                           stocks typically have high stock prices relative to
 . Small Mid/Cap Growth     measures of earnings and book value. Growth funds
  Fund                     are appropriate for investors who are willing to
                           accept more share-price volatility for the poten-
 . Small Cap Growth Fund    tial reward of higher long-term returns.

 . Growth & Income Fund     Blend Funds:

 . Equity Index Fund        Blend funds invest in both value and growth compa-
                           nies. Blend funds are appropriate for investors who
 . Small/Mid Cap CORE       seek both dividend and capital appreciation charac-
  Fund                     teristics.

Balanced Funds             Balanced funds invest in a combination of stocks
                           and bonds and actively manage the mix of stock and
 . Managed Fund             bonds within a target range. Domestic balanced
                           funds invest in U.S. stocks and bonds. Global bal-
 . Global Balanced Fund     anced funds invest in foreign and U.S. stocks and
                           bonds.

Bond Funds
Bond funds can be categorized in two ways--by average maturity and by credit
quality:

Average Maturity           Bond maturity is a key measure of interest rate
                           risk. A bond's maturity measures the time remaining
                           until the bond matures, or until the repayment of
                           the bond's principal comes due. The longer a bond's
                           maturity, the more sensitive the bond's price is to
                           changes in interest rates.

                           Short:

 . Money Market Fund        These funds invest primarily in bonds with short
                           maturities, typically less than four years. These
 . Short Term Bond          funds have less interest rate risk than intermedi-
  Fund                     ate-term bond funds.

                           Intermediate:

 . Bond Index Fund          These funds invest in bonds of all maturities and
                           maintain an average maturity which is typically
 . Active Bond Fund         between four and ten years. These funds have more
                           interest rate risk than short-term bond funds.
 . Global Bond Fund

 . High Yield Bond Fund

Credit Quality             Credit quality is a measure of the ability of a
                           bond issuer to meet its financial obligations and
                           repay principal and interest. High quality bonds
                           have less credit risk than lower quality bonds.
                           Investment grade bonds typically have "high" or
                           "medium" credit quality ratings (as defined below),
                           while high-yield bonds have "low" credit quality
                           ratings.

                           High:

 . Money Market Fund        These funds focus on the highest-rated, most
                           creditworthy bonds and typically maintain an aver-
 . Bond Index Fund          age credit quality rating of AAA/Aaa or AA/Aa.

 . Global Bond Fund

<PAGE>

                           Medium:
 . Short Term Bond Fund     These funds invest in bonds of all credit quality
                           levels with a focus on high-rated investment grade
 . Active Bond Fund         bonds. These funds typically maintain an average
                           credit quality rating of A or BBB/Baa.

                           Low:
 .  High Yield Bond         These funds invest primarily in lower rated bonds--
   Fund                    known as high yield or "junk" bonds. These funds
                           typically maintain a below investment-grade average
                           credit quality rating of BB/Ba or B.

International/Global Equity Funds
International funds invest primarily in securities markets outside the United
States. Global funds invest both in the United States and abroad. These funds
can be categorized by the types of markets they invest in.

                           Developed Markets:
 . Global Equity Fund       These funds invest primarily in the larger, well-
                           established developed or industralized markets
 . International            around the world. These funds have less foreign
  Equity Index Fund        securities risk than emerging market funds.

 . International
  Opportunities Fund

                           Emerging Markets:
 . Emerging Markets         These funds invest primarily in developing or
  Equity Fund              emerging markets and have more foreign securities
                           risk than funds that invest primarily in well-
                           established, developed markets.

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

In the following pages, any fund investment strategy that is stated as a per-
centage of a fund's assets applies at all times, not just at the time the fund
buys or sells an investment security. The trustees of the Trust can change the
investment goals and stragtegy of any fund without shareholder (i.e.,
contractowner) approval.

The financial highlights tables on the following pages detail the historical
performance of each fund, including total return information showing the
increase or decrease of an investment in the fund each year (assuming rein-
vestment of all dividends and distributions). The "total investment return"
shown for each fund does not reflect the expenses and charges of the applica-
ble separate accounts and variable contracts. Those expenses and charges vary
considerably from contract to contract and are described in the variable con-
tract prospectus to which this prospectus is attached. If the earliest period
shown in the financial highlights table is less than a full calendar year, the
two "Ratios" shown for that period have been annualized (i.e., projected as if
the fund had been in effect for a full year). However, the "total investment
return" and "turnover rate" for that period have not been annualized.

In this prospectus, the term "stock"' is used as a shorthand reference for
equity investments generally and the term "bond" is used as a shorthand refer-
ence for debt obligations generally.

Managed Fund

GOAL AND STRATEGY

This is a balanced stock and bond fund that seeks long-term growth in income
and capital.

The Fund invests primarily in a diversified mix of:

 . common stocks of large established U.S. companies;

 . bonds with maturities generally greater than 12 months; and

 . money market and other short-term debt securities with maturities generally
  not greater than 12 months.

The manager makes ongoing decisions about the mix between stocks and bonds. The
Manager has a target mix of 60% in equities and 40% in bonds, but actively man-
ages the mix within (+/-) 10 percentage points of the target mix.

The manager selects stocks and bonds using a combination of proprietary
research and quantitative tools. Stocks are purchased that are undervalued rel-
ative to the stock's history and have improving earnings growth prospects.
Bonds are purchased that are attractively priced and have cheap, predictable
cash flows. The Fund is managed using risk control techniques that maintain
risk and industry characteristics similar to the overall market.

The Fund normally invests its equity portion in 80 to 150 stocks, with at least
65% (usually higher) of its equity assets in large cap companies. The Fund may
invest up to 20% of its bond assets in foreign debt securities of developed
countries (denominated in foreign currencies) and up to 15% of its bond assets
in high yield bonds. The Fund normally has 5% or less of its assets in cash and
cash equivalents.

The Fund may purchase other types of securities, for example: American
Depository Receipts (ADRs), and certain derivatives (investments whose value is
based on indices or other securities). The manager actively uses derivatives,
such as futures and forwards, to adjust the Fund's average maturity relative to
the Lehman Brothers Aggregate Bond Index and to implement currency strategies.

In abnormal market conditions, the Fund may take temporary defensive measures--
such as holding unusually large amounts of cash and cash equivalents--that are
inconsistent with the Fund's primary investment strategy. In taking those mea-
sures, the Fund may not achieve its investment goal.

PAST PERFORMANCE

The graph shows how the fund's total return has varied from year to year, while
the table shows performance over time (along with a broad-based market index
for reference). This information may also help provide an indication of the
fund's risks and potential rewards. All figures assume dividend reinvestment.
Past performance does not indicate future results. The performance figures
below do not reflect the deduction of fees and charges payable under the
variable contracts. Such fees and charges would cause the investment returns
under the contracts to be less than that shown below.

MAIN RISKS
Primary


Market Risk: The value of the securities in the Fund may go down in response
to overall stock or bond market movements. Markets tend to move in cycles,
with periods of rising prices and periods of falling prices. Stocks tend to go
up and down in value more than bonds. If the Fund's investments are concen-
trated in certain sectors, the Fund's performance could be worse than the
overall market.


Manager Risk: The manager and its strategy may fail to produce the intended
results. The Fund could underperform its peers or lose money if the manager's
investment strategy does not perform as expected.


Investment Category Risk: The returns of the Fund's specific equity investment
category may lag the returns of the overall stock market. For example, the
Fund's "large cap" approach carries the risk that in certain markets large cap
stocks will underperform mid cap and small cap stocks.


Interest Rate Risk: When interest rates rise, the Fund's bond yields will gen-
erally rise and the Fund's bond prices will generally fall. When interest
rates fall, the reverse will generally occur. The longer the average remaining
maturity of bonds held by the Fund, the more sensitive the Fund is to interest
rate risk. This Fund has more interest rate risk than a short-term bond fund,
but less interest rate risk than a long-term bond fund.


Credit Risk: An issuer of a bond held by the Fund may default on its obliga-
tion to pay interest and repay principal. Also, the credit rating of a bond
held by the fund may be downgraded. In either case, the value of the bond held
by the Trust would fall. All bonds have some credit risk, but in general low-
er-rated bonds have higher credit risk.


Market Allocation Risk: The allocation of the Fund's assets among major asset
classes (i.e., stocks, bonds, and short-term debt securities) may (1) reduce
the Fund's holdings in a class whose value then increases unexpectedly, or (2)
increase the Fund's holdings in a class just prior to its experiencing a loss
of value.


Turnover Risk: In general, the greater the volume of buying and selling by a
fund (i.e., the higher its "turnover rate"), the greater the impact that bro-
kerage commissions and other transaction costs will have on the fund's perfor-
mance. Any turnover rate in excess of 100% is considered relatively high. Nor-
mally, the Fund's turnover rate will be greater than 100%.
Secondary


Foreign Risk: The Fund's foreign securities will pose special risks, due to
limited government regulation, lack of public information, economic, political
and social instability and foreign currency rate fluctuations. Factors such as
lack of liquidity, foreign ownership limits and restrictions on removing cur-
rency also pose special risks.


Derivatives Risk: Certain derivative instruments (such as options, futures and
swaps) can produce disproportionate gains or losses. They are generally con-
sidered more risky than direct equity investments. Also, in a down market,
derivatives could become harder to value or sell at a fair price.


High Yield Bond Risk: Junk bonds, defined as bond securities rated below BBB-
/Baa3, may be subject to more volatile or erratic price movements due to
investor sentiment. In a down market, these high yield securities become
harder to value or to sell at a fair price.


Prepayment/Call Risk: The Fund's share price or yield could be hurt if inter-
est rate movements cause the Fund's mortgage-related and callable securities
to be paid off substantially earlier than expected.

Growth & Income Fund

GOAL AND STRATEGY

This is a large cap stock fund that seeks long-term growth in income and capi-
tal.

The Fund invests primarily in a diversified mix of common stocks of large
established U.S. companies that are believed to offer:

 . favorable prospects for increasing dividends and growth in capital (i.e.,
  "value" companies); or

 . above-average potential for growth in revenues and earnings (i.e., "growth"
  companies).

The manager selects stocks using a combination of proprietary equity research
and quantitative tools. Stocks are purchased that are undervalued relative to
the stock's history and have improving earnings growth prospects. The Fund is
managed using risk control techniques that maintain risk and industry charac-
teristics similar to the S&P 500 Index.

The Fund normally invests in 80 to 150 stocks, with at least 65% (usually high-
er) of its assets in large cap companies. The Fund normally has 5% or less of
its assets in cash and cash equivalents.

The Fund may purchase other types of securities, for example: American Deposi-
tory Receipts (ADRs).

In abnormal market conditions, the Fund may take temporary defensive measures--
such as holding unusually large amounts of cash and cash equivalents--that are
inconsistent with the Fund's primary investment strategy. In taking those mea-
sures, the Fund may not achieve its investment goal.

Equity Index Fund

GOAL AND STRATEGY

This is a stock fund that seeks to track the performance of the S&P 500 Index,
which emphasizes the stocks of large U.S. companies.

The manager employs a passive management strategy by normally investing in all
500 stocks included in the Index. The manager invests in each stock in roughly
the same proportion as represented in the Index.

The manager seeks to replicate as closely as possible the aggregate risk char-
acteristics and industry diversification of the Index.

The Fund normally invests in all 500 stocks in the Index, but has no predeter-
mined number of stocks that it must hold. S&P may change the composition of the
Index from time to time. The manager will reflect those changes as soon as
practical.

The Fund is normally fully invested. The manager may invest in stock index
futures to maintain market exposure and manage cash flow.

The Fund may purchase other types of securities, for example: Standard & Poor's
Depository Receipts (SPDRs), American Depository Receipts (ADRs), cash equiva-
lents, and certain derivatives (investments whose value is based on indices or
other securities).

MAIN RISKS

Primary

Index Management Risk:  Certain factors such as the following may cause the
Fund to track the Index less closely:

 . The securities selected by the manager may not be fully representative of
  the Index.

 . Transaction expenses of the Fund may result in the Fund's performance being
  different than that of the Index.

 . The size and timing of the Fund's cash flows may result in the Fund's per-
  formance being different than that of the Index.
Also, index funds like this one will have more difficulty in taking defensive
positions in abnormal market conditions.

Market Risk: The value of the securities in the Fund may go down in response
to overall stock or bond market movements. Markets tend to move in cycles,
with periods of rising prices and periods of falling prices. Stocks tend to go
up and down in value more than bonds. If the Fund's investments are concen-
trated in certain sectors, the Fund's performance could be worse than the
overall market.

Manager Risk: The manager and its strategy may fail to produce the intended
results. The Fund could underperform its peers or lose money if the manager's
invest-ment strategy does not perform as expected.

Investment Category Risk: The returns of the Fund's specific equity investment
category may lag the returns of the overall stock market. For example, the
Fund's "large cap" approach carries the risk that in certain markets large cap
stocks will underperform mid cap and small cap stocks.

Secondary

Derivatives Risk: Certain derivative instruments (such as options, futures and
swaps) can produce disproportionate gains or losses. They are generally con-
sidered more risky than direct equity investments. Also, in a down market,
derivatives could become harder to value or sell at a fair price.

Large Cap Value Fund

GOAL AND STRATEGY

This is a large cap stock fund with a value emphasis that seeks long-term
growth in capital and substantial dividend income.

The Fund invests primarily in a diversified mix of common stocks of large
established U.S. companies that are believed to offer favorable prospects for
increasing dividends and growth in capital.

The manager employs a value approach in selecting stocks using proprietary
equity research. Stocks are purchased that are undervalued by various measures
such as the stock's current price relative to its earnings potential.

The manager looks for companies with:

 . established operating history;

 . above-average dividend yield relative to the S&P 500 Index;

 . low price/earnings ratio relative to the S&P 500 Index;

 . sound balance sheet and other positive financial characteristics; and

 . low stock price relative to the company's underlying value.

The Fund normally invests in 100 to 175 stocks, with at least 65% (usually
higher) of its assets in large cap companies. The Fund normally has 5% or less
of its assets in cash and cash equivalents.

The Fund may purchase other types of securities, for example: American Deposi-
tory Receipts (ADRs), foreign equity securities of developed countries, high
quality intermediate and short-term debt securities, and certain derivatives
(investments whose value is based on indices or other securities).

In abnormal market conditions, the Fund may take temporary defensive measures--
such as holding unusually large amounts of cash and cash equivalents--that are
inconsistent with the Fund's primary investment strategy. In taking those mea-
sures, the Fund may not achieve its investment goal.

PAST PERFORMANCE

The graph shows how the fund's total return has varied from year to year, while
the table shows performance over time (along with a broad-based market index
for reference). This information may also help provide an indication of the
fund's risks and potential rewards. All figures assume dividend reinvestment.
Past performance does not indicate future results. The performance figures
below do not reflect the deduction of fees and charges payable under the
variable contracts. Such fees and charges would cause the investment returns
under the contracts to be less than that shown below.

will underperform "growth" stocks. Also, the Fund's "large cap" approach car-
ries the risk that in certain markets large cap stocks will underperform small
cap and mid cap stocks.

Secondary

Foreign Risk: The Fund's foreign securities will pose special risks, due to
limited government regulation, lack of public information, economic, political
and social instability and foreign currency rate fluctuations. Factors such as
lack of liquidity, foreign ownership limits and restrictions on removing cur-
rency also pose special risks.

Derivatives Risk: Certain derivative instruments (such as options, futures and
swaps) can produce disproportionate gains or losses. They are generally consid-
ered more risky than direct equity investments. Also, in a down market, deriva-
tives could become harder to value or sell at a fair price.

Large Cap Growth Fund

GOAL AND STRATEGY

This is a large cap stock fund with a growth emphasis that seeks growth in
capital.

The Fund invests primarily in a diversified mix of common stocks of large
established U.S. companies that are believed to offer above-average potential
for growth in revenues and earnings.

The manager selects stocks using a combination of proprietary equity research
and quantitative tools. Stocks are purchased that are undervalued relative to
the stock's history and have improving earnings growth prospects. The Fund is
managed using risk control techniques that maintain risk and industry charac-
teristics similar to the Russell 1000(R) Growth Index.

The Fund normally invests in 80 to 150 stocks, with at least 65% (usually high-
er) of its assets in large cap companies. The Fund normally has 5% or less of
its assets in cash and cash equivalents.

The Fund may purchase other types of securities, for example: American Deposi-
tory Receipts (ADRs), and certain derivatives (investments whose value is based
on indices or other securities).

In abnormal market conditions, the Fund may take temporary defensive measures--
such as holding unusually large amounts of cash and cash equivalents--that are
inconsistent with the Fund's primary investment strategy. In taking those mea-
sures, the Fund may not achieve its investment goal.

This is a mid cap stock fund with a value emphasis that seeks long-term growth
in capital.

The Fund invests primarily in the common stocks of mid-sized U.S. companies
that are believed to sell at a discount to their intrinsic value.

The manager selects stocks using proprietary equity research. Stocks are pur-
chased that are undervalued by various measures such as the stock's current
price relative to its earnings potential.

The manager looks for undervalued companies with:

 . sound balance sheet and other financial characteristics;

 . consistent cash flow;

 . strong position relative to the competition; and

 . high level of stock ownership among management.

The Fund normally invests in 50 to 75 stocks, with at least 65% (usually high-
er) of its assets in mid cap companies. The Fund normally has 5% or less of its
assets in cash and cash equivalents.

The Fund may purchase other types of securities, for example: American Deposi-
tory Receipts (ADRs), and certain derivatives (investments whose value is based
on indices or other securities).

In abnormal market conditions, the Fund may take temporary defensive measures--
such as holding unusually large amounts of cash and cash equivalents--that are
inconsistent with the Fund's primary investment strategy. In taking those mea-
sures, the Fund may not achieve its investment goal.

PAST PERFORMANCE

The graph shows how the fund's total return has varied from year to year, while
the table shows performance over time (along with a broad-based market index
for reference). This information may help provide an indication of the fund's
risks and potential rewards. All figures assume dividend reinvestment. Past
performance does not indicate future results. The performance figures below do
not reflect the deduction of fees and charges payable under the variable
contracts. Such fees and charges would cause the investment returns under the
contracts to be less than that shown below.

MAIN RISKS

Primary

Small /Mid Cap Stock Risk: The Fund's investment in smaller or mid-sized compa-
nies may be subject to more erratic price movements than investment in large
established companies.

Market Risk: The value of the securities in the Fund may go down in response to
overall stock or bond market movements. Markets tend to move in cycles, with
periods of rising prices and periods of falling prices. Stocks tend to go up
and down in value more than bonds. If the Fund's investments are concentrated
in certain sectors, the Fund's performance could be worse than the overall mar-
ket.

Manager Risk: The manager and its strategy may fail to produce the intended
results. The Fund could underperform its peers or lose money if the manager's
investment strategy does not perform as expected.

Investment Category Risk: The returns of the Fund's specific equity investment
category may lag the returns of the overall stock market. For example, the
Fund's "value" approach carries the risk that in certain markets "value" stocks
will underperform "growth" stocks. Also, the Fund's "mid cap" approach carries
the risk that in certain markets mid cap stocks will underperform small cap and
large cap stocks.

Concentration Risk: The Fund's investment in securities of a smaller number of
issuers could produce more volatile performance relative to funds that invest
in a larger number of issuers. The more concentrated a fund's holdings are, the
more likely it is a specific security's poor performance will hurt the fund
significantly.

Turnover Risk: In general, the greater the volume of buying and selling by a
fund (i.e., the higher its "turnover rate"), the greater the impact that bro-
kerage commissions and other transaction costs will have on the fund's perfor-
mance. Any turnover rate in excess of 100% is considered relatively high. Nor-
mally, the Fund's turnover rate will be greater than 100%.

Secondary

Derivatives Risk: Certain derivative instruments (such as options, futures and
swaps) can produce disproportionate gains or losses. They are generally consid-
ered more risky than direct equity investments. Also, in a down market, deriva-
tives could become harder to value or sell at a fair price.

Mid Cap Growth Fund

GOAL AND STRATEGY

This is a non-diversified mid cap stock fund with a growth emphasis that seeks
long-term growth in capital.

The Fund invests primarily in the common stocks of mid-sized U.S. companies
that are believed to offer above-average potential for growth in revenues and
earnings.

The manager selects stocks using proprietary equity research. Stocks are pur-
chased that are expected to have earnings growth potential that may not be rec-
ognized by the investment community. The manager selects stocks without regard
to any pre- defined industry or sector selection criteria.

The manager looks for companies experiencing:

 . above-average growth relative to their peers or the general economy; and

 . positive change due to new product developments, improved regulatory environ-
  ment or a new management team.

The Fund is non-diversified, which means it can take larger positions in a
smaller number of issuers. Based upon its current size and strategy, the Fund
invests in 35 to 75 stocks, with at least 65% of its assets in mid cap compa-
nies. The Fund normally has 15% or less of its assets in cash and cash equiva-
lents.

The Fund may purchase other types of securities, for example: American Deposi-
tory Receipts (ADRs), foreign equity securities of developed countries, and
certain derivatives (investments whose value is based on indices or other
securities).

In abnormal market conditions, the Fund may take temporary defensive measures--
such as holding unusually large amounts of cash and cash equivalents--that are
inconsistent with the Fund's primary investment strategy. In taking those mea-
sures, the Fund may not achieve its investment goal.

MAIN RISKS

Primary

Small /Mid Cap Stock Risk: The Fund's investment in smaller or mid-sized compa-
nies may be subject to more erratic price movements than investment in large
established companies.

Non-Diversified Fund Risk: The Fund's larger position in individual issuers and
in a smaller number of issuers could produce more volatile performance relative
to more diversified funds. The less diversified a fund's holdings are, the more
likely it is that a specific security's poor performance will hurt the fund
significantly.

Market Risk: The value of the securities in the Fund may go down in response to
overall stock or bond market movements. Markets tend to move in cycles, with
periods of rising prices and periods of falling prices. Stocks tend to go up
and down in value more than bonds. If the Fund's investments are concentrated
in certain sectors, the Fund's performance could be worse than the overall mar-
ket.

Manager Risk: The manager and its strategy may fail to produce the intended
results. The Fund could underperform its peers or lose money if the manager's
investment strategy does not perform as expected.

Investment Category Risk: The returns of the Fund's specific equity investment
category may lag the returns of the overall stock market. For example, the
Fund's "growth" approach carries the risk that in certain markets "growth"
stocks will underperform "value" stocks. Also, the Fund's "mid cap" approach
carries the risk that in certain markets mid cap stocks will underperform small
cap and large cap stocks.

Concentration Risk: The Fund's investment in securities of a smaller number of
issuers could produce more volatile performance relative to funds that invest
in a larger number of issuers. The more concentrated a fund's holdings are, the
more likely it is a specific security's poor performance will hurt the fund
significantly.

Turnover Risk: In general, the greater the volume of buying and selling by a
fund (i.e., the higher its "turnover rate"), the greater the impact that bro-
kerage commissions and other transaction costs will have on the fund's perfor-
mance. Any turnover rate in excess of 100% is considered relatively high. Nor-
mally, the Fund's turnover rate will be greater than 100%.

Secondary

Foreign Risk: The Fund's foreign securities will pose special risks, due to
limited government regulation, lack of public information, economic, political
and social instability and foreign currency rate fluctuations. Factors such as
lack of liquidity, foreign ownership limits and restrictions on removing cur-
rency also pose special risks.

Derivatives Risk: Certain derivative instruments (such as options, futures and
swaps) can produce disproportionate gains or losses. They are generally consid-
ered more risky than direct equity investments. Also, in a down market, deriva-
tives could be- come harder to value or sell at a fair price.

Real Estate Equity Fund

GOAL AND STRATEGY

This is a real estate stock fund that seeks above-average income and long-term
growth in capital.

The Fund invests primarily in:

 . equity securities of real estate investment trusts (REITs) that own commer-
  cial and multi-family residential real estate; and

 . equity securities of real estate operating companies (i.e., companies with at
  least 75% of revenue, income or fair asset value derived from real estate).

The manager selects real estate stocks using a combination of proprietary,
equity research and quantitative tools. Real estate stocks are purchased that
are undervalued relative to the stock's history and the market and have improv-
ing earnings growth prospects.

The manager looks for real estate stocks with:

 . proven track records,

 . strong management whose interests are aligned with shareholders,

 . attractive real estate holdings, and

 . a flexible financial structure.

The manager employs risk control techniques to maintain risk, style and indus-
try characteristics similar to the public equity real estate market. The Fund
normally invests in 30 to 60 securities. The Fund normally has 5% or less of
its assets in cash and cash equivalents.

The Fund also may purchase other types of securities, for example: American
Depository Receipts (ADRs), convertible securities, and equity securities of
non-real estate businesses whose real estate holdings are significant in rela-
tion to their market capitalization.

In abnormal market conditions, the Fund may take temporary defensive measures--
such as holding unusually large amounts of cash and cash equivalents--that are
inconsistent with the Fund's primary investment strategy. In taking those mea-
sures, the Fund may not achieve its investment goal.

MAIN RISKS

Primary

Real Estate Securities Risk: Real estate investment trusts (REITs) or other
real estate-related equity securities may be affected by changes in the value
of the underlying property owned by the trust. Mortgage REITs may be affected
by the quality of any credit extended. Other potential risks include the possi-
bility of failing to qualify for tax-free pass-through of income under the
Internal Revenue Code or failing to maintain exemption under the Investment
Company Act of 1940.

Market Risk: The value of the securities in the Fund may go down in response to
overall stock or bond market movements. Markets tend to move in cycles, with
periods of rising prices and periods of falling prices. Stocks tend to go up
and down in value more than bonds. If the Fund's investments are concentrated
in certain sectors, the Fund's performance could be worse than the overall mar-
ket.

Manager Risk: The manager and its strategy may fail to produce the intended
results. The Fund could underperform its peers or lose money if the manager's
investment strategy does not perform as expected.

Concentration Risk: The Fund's investment in securities of a smaller number of
issuers could produce more volatile performance relative to funds that invest
in a larger number of issuers. The more concentrated a fund's holdings are, the
more likely it is a specific security's poor performance will hurt the fund
significantly.

Small /Mid Cap Stock Risk: The Fund's investment in smaller or mid-sized compa-
nies may be subject to more erratic price movements than investment in large
established companies.

Small/Mid Cap CORE Fund
GOAL AND STRATEGY

This is a small/mid cap stock fund that seeks long-term growth in capital.

The Fund invests primarily in a diversified mix of the common stocks of small
and mid-sized U.S. companies that are believed to offer:

 . favorable prospects for increasing dividends and capital appreciation (i.e.,
  "value" companies); and

 . above-average potential for growth in revenues and earnings (i.e. "growth"
  companies).

The manager selects stocks using a combination of quantitative techniques and
equity research. The manager employs an investment process known as CORE, "Com-
puter Optimized, Research-Enhanced," that employs a proprietary quantitative
model. Stocks are purchased that have strong expected earnings growth and
momentum and better valuation and risk characteristics than the Russell
2500(TM) Index. The Fund is managed using risk control techniques to maintain
risk, style, capitalization and industry characteristics similar to the Russell
2500(TM) Index.

The Fund normally invests in 200 to 600 stocks, with at least 65% (usually
higher) of the Fund's assets in small cap and mid cap companies. The Fund nor-
mally has 10% or less of its assets in cash and cash equivalents.

The Fund may purchase other types of securities, for example: American Deposi-
tory Receipts (ADRs), Standard & Poor's Depository Receipts (SPDRs), and cer-
tain derivatives (investments whose value is based on indices or other securi-
ties).

In abnormal market conditions, the Fund may take temporary defensive measures--
such as holding unusually large amounts of cash and cash equivalents--that are
inconsistent with the Fund's primary investment strategy. In taking those mea-
sures, the Fund may not achieve its investment goal.

MAIN RISKS

Primary

Small /Mid Cap Stock Risk: The Fund's investment in smaller or mid-sized compa-
nies may be subject to more erratic price movements than investment in large
established companies.

Market Risk: The value of the securities in the Fund may go down in response to
overall stock or bond market movements. Markets tend to move in cycles, with
periods of rising prices and periods of falling prices. Stocks tend to go up
and down in value more than bonds. If the Fund's investments are concentrated
in certain sectors, the Fund's performance could be worse than the overall mar-
ket.

Manager Risk: The manager and its strategy may fail to produce the intended
results. The Fund could underperform its peers or lose money if the manager's
investment strategy does not perform as expected.

Investment Category Risk: The returns of the Fund's specific equity investment
category may lag the returns of the overall stock market. For example, the
Fund's "small/mid cap" approach carries the risk that in certain markets
small/mid cap stocks will underperform large cap stocks.

Turnover Risk: In general, the greater the volume of buying and selling by a
fund (i.e., the higher its "turnover rate"), the greater the impact that bro-
kerage commissions and other transaction costs will have on the fund's perfor-
mance. Any turnover rate in excess of 100% is considered relatively high. The
Fund had unusually high turnover in 1999 and is expected to experience similar
turnover in 2000. This higher than expected turnover is due to (i) the rela-
tively small size of the Fund, which magnifies the effect of contributions and
redemptions, and (ii) the high volatility of the market, which in 1999 resulted
in the subadviser implementing procedures to reduce the Fund's tracking risk.
Normally, the Fund's turnover rate will be less than 100%.

Secondary

Derivatives Risk: Certain derivative instruments (such as options, futures and
swaps) can produce disproportionate gains or losses. They are generally consid-
ered more risky than direct equity investments. Also, in a down market, deriva-
tives could become harder to value or sell at a fair price.

Small/Mid Cap Growth Fund

GOAL AND STRATEGY

This is a small/mid cap stock fund with a growth emphasis that seeks long-term
growth in capital.

The Fund invests primarily in the common stocks of small and mid-sized U.S.
companies that are believed to offer above-average potential for growth in rev-
enues and earnings.

The manager selects stocks using a combination of proprietary quantitative and
qualitative equity research. Quantitative screening seeks to identify a group
of high-quality companies with above-average growth characteristics relative to
industry peers. Equity research seeks to identify individual companies from
that group with a higher potential for long term earnings growth and capital
appreciation.

The manager buys companies that seem attractive based on a combination of cri-
teria, among others:

 . Superior historical earnings growth,

 . Prospects for above-average growth,

 . Attractive valuations,

 . Strong market positions,

 . Favorable new products, and

 . Superior management.

The Fund is broadly diversified by industry sector. The Fund normally invests
in 60 to 100 stocks, with at least 65% (usually higher) of its assets in small
and mid cap companies. The Fund normally has 5% or less of its assets in cash
and cash equivalents.

The Fund may purchase other types of securities, for example: American Deposi-
tory Receipts (ADRs), and certain derivatives (investments whose value is based
on indices or other securities).

In abnormal market conditions, the Fund may take temporary defensive measures--
such as holding unusually large amounts of cash and cash equivalents--that are
inconsistent with the Fund's primary investment strategy. In taking those mea-
sures, the Fund may not achieve its investment goal.

MAIN RISKS

Primary

Small /Mid Cap Stock Risk: The Fund's investment in smaller or mid-sized compa-
nies may be subject to more erratic price movements than investment in large
established companies.

Market Risk: The value of the securities in the Fund may go down in response to
overall stock or bond market movements. Markets tend to move in cycles, with
periods of rising prices and periods of falling prices. Stocks tend to go up
and down in value more than bonds. If the Fund's investments are concentrated
in certain sectors, the Fund's performance could be worse than the overall mar-
ket.

Manager Risk: The manager and its strategy may fail to produce the intended
results. The Fund could underperform its 25 peers or lose money if the manager's
investment strategy does not perform as expected.

Investment Category Risk: The returns of the Fund's specific equity investment
category may lag the returns of the overall stock market. For example, the
Fund's "growth" approach carries the risk that in certain markets "growth"
stocks will underperform "value" stocks. Also, the Fund's "small/mid cap"
approach carries the risk that in certain markets small/mid cap stocks will
underperform large cap stocks.

Concentration Risk: The Fund's investment in securities of a smaller number of
issuers could produce more volatile performance relative to funds that invest
in a larger number of issuers. The more concentrated a fund's holdings are, the
more likely it is a specific security's poor performance will hurt the fund
significantly.

Turnover Risk: In general, the greater the volume of buying and selling by a
fund (i.e., the higher its "turnover rate"), the greater the impact that bro-
kerage commissions and other transaction costs will have on the fund's perfor-
mance. Any turnover rate in excess of 100% is considered relatively high. The
Fund had a high turnover rate in 1999 because of a change in management and a
change in the Fund's investment strategy. These changes required a restructur-
ing of the Fund's investments. In future years, the Fund's turnover rate will
normally be less than 100%.

Small Cap Value Fund

GOAL AND STRATEGY

This is a small cap stock fund with a value emphasis that seeks long-term
growth in capital.

The Fund invests primarily in a diversified mix of the common stocks of small
U.S. companies that are believed to offer favorable prospects for increasing
dividends and capital appreciation.

The manager applies a combination of quantitative techniques and equity
research to identify the best values among small company stocks.

Stocks are evaluated based on multiple factors, including:

 . earnings-to-price ratios;

 . earnings estimate revisions;

 . relative price strength; and

 . share issuance/buyback.

The Fund is managed using risk control techniques to maintain risk, style, cap-
italization and industry characteristics similar to the Russell 2000(R) Value
Index. The Fund normally invests in 150 to 250 stocks, with at least 65% (usu-
ally higher) of its assets in small cap companies. The Fund normally has 5% or
less of its assets in cash and cash equivalents.

The Fund may purchase other types of securities, for example: American Deposi-
tory Receipts (ADRs), and certain derivatives (investments whose value is based
on indices or other securities).

In abnormal market conditions, the Fund may take temporary defensive measures--
such as holding unusually large amounts of cash and cash equivalents--that are
inconsistent with the Fund's primary investment strategy. In taking those mea-
sures, the Fund may not achieve its investment goal.

in certain sectors, the Fund's performance could be worse than the overall mar-
ket.

Manager Risk: The manager and its strategy may fail to produce the intended
results. The Fund could underperform its peers or lose money if the manager's
investment strategy does not perform as expected.

Investment Category Risk: The returns of the Fund's specific equity investment
category may lag the returns of the overall stock market. For example, the
Fund's "value" approach carries the risk that in certain markets "value" stocks
will underperform "growth" stocks. Also, the Fund's "small cap" approach car-
ries the risk that in certain markets small cap stocks will underperform mid
cap and large cap stocks.

Turnover Risk: In general, the greater the volume of buying and selling by a
fund (i.e., the higher its "turnover rate"), the greater the impact that bro-
kerage commissions and other transaction costs will have on the fund's perfor-
mance. Any turnover rate in excess of 100% is considered relatively high. Nor-
mally, the Fund's turnover rate will be greater than 100%.

Secondary

Derivatives Risk: Certain derivative instruments (such as options, futures and
swaps) can produce disproportionate gains or losses. They are generally consid-
ered more risky than direct equity investments. Also, in a down market, deriva-
tives could become harder to value or sell at a fair price.

Small Cap Growth Fund

GOAL AND STRATEGY

This is a small cap stock fund with a growth emphasis that seeks long-term
growth in capital.

The Fund invests primarily in a diversified mix of the common stocks of small
U.S. companies that are believed to offerabove-average potential for growth in
revenues and earnings.

The manager selects stocks using proprietary equity research. Stocks are pur-
chased that are expected to have rapid earnings growth that is not yet widely
recognized by the investment community.

The manager looks for companies with:

 . demonstrated annual 20% earnings growth over 3 years and/or similar future
  growth expectations;

 . dominant market niche or poised to become market leaders; and

 . high quality senior management with coherent business strategies.

The Fund is highly diversified by sector and number of individual stocks. The
Fund's sector weightings are broadly diversified and managed relative to those
of the Russell 2000(R) Growth Index. The Fund normally invests in 150 to 220
stocks, with at least 65% (usually higher) of its assets in small cap compa-
nies. The Fund normally has 5% or less of its assets in cash and cash equiva-
lents.

The Fund may purchase other types of securities, for example: American Deposi-
tory Receipts (ADRs), and certain derivatives (investments whose value is based
on indices or other securities).

In abnormal market conditions, the Fund may take temporary defensive measures--
such as holding unusually large amounts of cash and cash equivalents--that are
inconsistent with the Fund's primary investment strategy. In taking those mea-
sures, the Fund may not achieve its investment goal.

PAST PERFORMANCE

The graph shows how the fund's total return has varied from year to year, while
the table shows performance over time (along with a broad-based market index
for reference). This information may help provide an indication of the fund's
risks and potential rewards. All figures assume dividend reinvestment. Past
performance does not indicate future results. The performance figures below do
not reflect the deduction of fees and charges payable under the variable
contracts. Such fees and charges would cause the investment returns under the
contracts to be less than that shown below.

MAIN RISKS

Primary

Small /Mid Cap Stock Risk: The Fund's investment in smaller or mid-sized compa-
nies may be subject to more erratic price movements than investment in large
established companies.

Market Risk: The value of the securities in the Fund may go down in response to
overall stock or bond market movements. Markets tend to move in cycles, with
periods of rising prices and periods of falling prices. Stocks tend to go up
and down in value more than bonds. If the Fund's investments are concentrated
in certain sectors, the Fund's performance could be worse than the overall mar-
ket.

Manager Risk: The manager and its strategy may fail to produce the intended
results.
The Fund could underperform its peers or lose money if the manager's investment
strategy does not perform as expected.

Investment Category Risk: The returns of the Fund's specific equity investment
category may lag the returns of the overall stock market. For example, the
Fund's "growth" approach carries the risk that in certain markets "growth"
stocks will underperform "value" stocks. Also, the Fund's "small cap" approach
carries the risk that in certain markets small cap stocks will underperform mid
cap and large cap stocks.

Turnover Risk: In general, the greater the volume of buying and selling by a

Global Equity Fund
GOAL AND STRATEGY

This is a global stock fund that seeks long-term growth in capital.

The Fund primarily invests in a diversified mix of common stocks of:

 . large established U.S. companies; and

 . large established foreign companies located in countries throughout the
  world, including developed, newly industrialized, and emerging countries.

The manager makes ongoing decisions about the mix between U.S. and foreign
stocks. The manager has a target mix of 40% in U.S. stocks and 60% in foreign
stocks, but actively manages the mix within (+/-) 20 percentage points of the
target mix.

The manager uses global economic and industry analysis to identify global eco-
nomic and industry themes. The manager looks for companies that will benefit
from:

 . global economic trends;

 . promising technologies or products; and

 . specific country opportunities resulting from changing geopolitical, currency
  or economic relationships.

The manager purchases stocks of companies that are:

 . in growth industries;

 . efficient producers; and

 . undervalued relative to long-term growth potential.

The Fund invests:

 . in at least 3 different countries (including the U.S.), but normally in more
  than 15 countries; and

 . no more than 10% of its assets in emerging markets stocks.

Although the Fund may employ foreign currency hedging techniques, the Fund nor-
mally maintains the currency exposure of the underlying equity investments.

The Fund normally invests in 90 to 120 stocks, with at least 65% (usually high-
er) of its assets in large cap companies. The Fund normally has 5% or less of
its assets in cash and cash equivalents.

The Fund may purchase other types of securities, for example: American Deposi-
tory Receipts (ADRs), Global Depository Receipts (GDRs), European Depository
Receipts (EDRs), and certain derivatives (investments whose value is based on
indices or other securities).

In abnormal market conditions, the Fund may take temporary defensive measures--
such as holding unusually large amounts of cash and cash equivalents or invest-
ing 100% of its assets in U.S. companies--that are inconsistent with the Fund's
primary investment strategy. In taking those measures, the Fund may not achieve
its investment goal.

MAIN RISKS

Primary

Foreign Risk: The Fund's foreign securities will pose special risks, due to
limited government regulation, lack of public information, economic, political
and social instability and foreign currency rate fluctuations. Factors such as
lack of liquidity, foreign ownership limits and restrictions on removing cur-
rency also pose special risks. All foreign securities have some degree of for-
eign risk. However, to the extent the Fund invests in emerging market coun-
tries, it will have a significantly higher degree of foreign risk than if it
invested exclusively in developed or newly-industrialized countries.
Market Risk: The value of the securities in the Fund may go down in response
to overall stock or bond market movements. Markets tend to move in cycles,
with periods of rising prices and periods of falling prices. Stocks tend to go
up and down in value more than bonds. If the Fund's investments are concen-
trated in certain sectors, the Fund's performance could be worse than the
overall market.

Market Allocation Risk: The allocation of the Fund's assets among domestic and
international equity regions may (1) reduce the Fund's holdings in a region
whose value then increases unexpectedly, or (2) increase the Fund's holdings
in a region just prior to its experiencing a loss of value.
Manager Risk: The manager and its strategy may fail to produce the intended
results. The Fund could underperform its peers or lose money if the manager's
investment strategy does not perform as expected.


Secondary

Derivatives Risk: Certain derivative instruments (such as options, futures and
swaps) can produce disproportionate gains or losses. They are generally con-
sidered more risky than direct equity investments. Also, in a down market,
derivatives could become harder to value or sell at a fair price.

Global Balanced Fund
(Formerly International Balanced Fund)

GOAL AND STRATEGY

This is a non-diversified global balanced stock and bond fund that seeks long-
term growth in income and capital.

The Fund invests primarily in a mix of:

 . U.S. and foreign common stocks of large companies within developed markets;
  and

 . U.S. and foreign investment grade bonds of issuers within developed markets
  with maturities generally greater than 12 months.

The manager makes ongoing decisions about the mix between stocks and bonds. The
manager has a target mix of 65% stocks and 35% bonds, but actively manages the
mix within (+/-) 10 percentage points of the target mix.

The Fund invests:

 . in at least 3 different countries, but normally invests in 10 to 20 coun-
  tries; and

 . no more than 10% of its assets in emerging market stocks and bonds.

The manager selects stocks and bonds using fundamental value analysis to iden-
tify fairly priced investments with long-term sustainable cash flows. The man-
ager determines fundamental value by focusing on:

 . current market prices relative to fundamental values;

 . broad-based indices for stocks, bonds, and markets; and

 . economic variables such as productivity, inflation and global competitive-
  ness.

The Fund is non-diversified, which means that it can take larger positions in a
smaller number of issuers. However, the Fund normally invests in 125 to 250
stocks within the stock portion. The Fund normally has 10% or less of its
assets in cash and cash equivalents.

The Fund may purchase other types of securities, for example: American Deposi-
tory Receipts (ADRs), Global Depository Receipts (GDRs), European Depository
Receipts (EDRs), high yield bonds, and certain derivatives (investments whose
value is based on indices or other securities).

The manager actively uses derivatives, such as futures and forwards, to manage
the Fund's average maturity relative to the Salomon Brothers World Government
Bond Index Unhedged and to implement foreign currency strategies. Currency man-
agement strategies are primarily used for hedging purposes and to protect
against anticipated changes in foreign currency exchange rates.

In abnormal market conditions, the Fund may take temporary defensive measures--
such as holding unusually large amounts of cash and cash equivalents--that are
inconsistent with the Fund's primary investment strategy. In taking those mea-
sures, the Fund may not achieve its investment goal.

PAST PERFORMANCE

The graph shows how the fund's total return has varied from year to year, while
the table shows performance over time (along with a broad-based market index
for reference). This information may help provide an indication of the fund's
risks and potential rewards. All figures assume dividend reinvestment. Past
performance does not indicate future results. The performance figures below do
not reflect the deduction of fees and charges payable under the variable
contracts. Such fees and charges would cause the investment returns under the
contracts to be less than that shown below.

MAIN RISKS

Primary

Foreign Risk: The Fund's foreign securities will pose special risks, due to
limited government regulation, lack of public information, economic, political
and social instability and foreign currency rate fluctuations. Factors such as
lack of liquidity, foreign ownership limits and restrictions on removing cur-
rency also pose special risks. All foreign securities have some degree of for-
eign risk. However, to the extent the Fund invests in emerging market coun-
tries, it will have a significantly higher degree of foreign risk than if it
invested exclusively in developed or newly-industrialized countries.

Non-Diversified Fund Risk: The Fund's larger position in foreign government
securities could produce more volatile performance relative to funds with
smaller positions. The less diversified a fund's holdings are, the more likely
it is that a specific security's poor performance will hurt the fund signifi-
cantly.

Market Risk: The value of the securities in the Fund may go down in response to
overall stock or bond market movements. Markets tend to move in cycles, with
periods of rising prices and periods of falling prices. Stocks tend to go up
and down in value more than bonds. If the Fund's investments are concentrated
in certain sectors, the Fund's performance could be worse than the overall mar-
ket.
Manager Risk: The manager and its strategy may fail to produce the intended
results. The Fund could underperform its peers or lose money if the manager's
investment strategy does not perform as expected.

Investment Category Risk: The returns of the Fund's specific equity investment
category may lag the returns of the overall stock market. For example, the
Fund's "value" approach carries the risk that in certain markets "value" stocks
will underperform "growth" stocks. Also, the Fund's "large/mid cap" approach
carries the risk that large/mid cap stocks will underperform small cap stocks.

Market Allocation Risk: The allocation of the Fund's assets between the major
asset classes (i.e., stocks and bonds) may (1) reduce the Fund's holdings in a
class whose value then increases unexpectedly, or (2) increase the Fund's hold-
ings in a class just prior to its experiencing a loss of value.

Interest Rate Risk: When interest rates rise, the Fund's bond yields will gen-
erally rise and the Fund's bond prices will generally fall. When interest rates
fall, the reverse will generally occur. The longer the average remaining matu-
rity of bonds held by the Fund, the more sensitive the Fund is to interest rate
risk. This Fund has more interest rate risk than a short-term bond fund, but
less interest rate risk than a long-term bond fund.
Credit Risk: An issuer of a bond held by the Fund may default on its obligation
to pay interest and repay principal. Also, the credit rating of a bond held by
the fund may be downgraded. In either case, the value of the bond held by the
Trust would fall. All bonds have some credit risk, but in general lower-rated
bonds have higher credit risk.

Turnover Risk. In general, the greater the volume of buying and selling by a
fund (i.e., the higher its "turnover rate"), the greater the impact that bro-
kerage commissions and other transaction costs will have on the fund's perfor-
mance. Any turnover rate in excess of 100% is considered relatively high. Nor-
mally, the Fund's turnover rate will be greater than 100%.

Secondary

Derivatives Risk: Certain derivative instruments (such as options, futures and
swaps) can produce disproportionate gains or losses. They are generally consid-
ered more risky than direct equity investments. Also, in a down market, deriva-
tives could become harder to value or sell at a fair price.

High Yield Bond Risk. Junk bonds, defined as bond securities rated below BBB-
/Baa3, may be subject to more volatile or erratic price movements due to
investor sentiment. In a down market, these high yield securities become harder
to value or to sell at a fair price.

International Equity Index Fund

GOAL AND STRATEGY

This is an international stock fund that seeks to track the performance of
broad-based equity indices of foreign companies in developed and emerging mar-
kets.

The Fund is managed relative to a target mix of 90% in the MSCI EAFE GDP Index
and 10% in the MSCI EMF Index. The EAFE GDP Index, known as the Europe Austral-
asia and Far East Index, includes foreign companies in developed markets, with
country index weights based upon a country's Gross Domestic Product (GDP). The
EMF Index, known as the Emerging Markets Free Index, includes foreign companies
in emerging markets, with country index weights based upon a country's market
capitalization.

The manager employs a passive management strategy using quantitative techniques
to invest in a representative sample of stocks in the Index. The manager
selects stocks in an attempt to track, as closely as possible, the characteris-
tics of the Index, including country and sector weights. The Fund normally
invests in 400 to 1,200 stocks.

The Index composition changes from time to time. The manager will reflect those
changes as soon as practical.

The Fund is normally fully invested. The manager may invest in stock index
futures to maintain market exposure and manage cash flow. Although the Fund may
employ foreign currency hedging techniques, the Fund normally maintains the
currency exposure of the underlying equity investments.


The Fund may purchase other types of securities, for example: American Deposi-
tory Receipts (ADRs), Global Depository Receipts (GDRs), European Depository
Receipts (EDRs), cash equivalents, and certain derivatives (investments whose
value is based on indices or other securities).

Note: "MSCI EAFE GDP Index" and "MSCI EMF Index" are the exclusive property of
Morgan Stanley & Co., Incorporated and are registered service marks of Morgan
Stanley Capital International.

tries, it will have a significantly higher degree of foreign risk than if it
invested exclusively in developed or newly-industrialized countries.


Index Management Risk: Certain factors such as the following may cause the
Fund to track the Index less closely:


 . The securities selected by the manager may not be fully representative of
  the Index.

 . Transaction expenses of the Fund may result in the Fund's performance being
  different than that of the Index.
 . The size and timing of the Fund's cash flows may result in the Fund's per-
  formance being different than that of the Index.


Also, index funds like this one will have more difficulty in taking defensive
positions in abnormal market conditions.


Market Risk: The value of the securities in the Fund may go down in response
to overall stock or bond market movements. Markets tend to move in cycles,
with periods of rising prices and periods of falling prices.

Stocks tend to go up and down in value more than bonds. If the Fund's invest-
ments are concentrated in certain sectors, the Fund's performance could be
worse than the overall market.

derivatives could become harder to value or sell at a fair price.

International Opportunities Fund

GOAL AND STRATEGY

This is an international stock fund that seeks long-term growth in capital.

The Fund primarily invests in a diversified mix of common stocks of large
established and medium-sized foreign companies located throughout the world,
including developed, newly industrialized, and emerging countries.

The manager determines the distribution among countries and regions by using a
combination of fundamental research and economic analysis, emphasizing:

 . prospects for relative economic growth between foreign countries;

 . expected levels of inflation;

 . government policies influencing business conditions; and

 . outlook for currency relationships.
The manager selects stocks that have growth characteristics such as:

 . leading market position or technological leadership;

 . high return on invested capital;

 . healthy balance sheets with relatively low debt;

 . strong competitive advantage;

 . strength of management; and

 . earnings growth and cash flow sufficient to support growing dividends.

The Fund invests:

 . in at least 3 different countries; and

 . no more than 20% of its assets in emerging market stocks.

Although the Fund may employ foreign currency hedging techniques, the Fund nor-
mally maintains the currency exposure of the underlying equity investments.
The Fund normally invests in 200 to 300 stocks in 15 to 20 countries. The Fund
normally has 10% or less of its assets in cash and cash equivalents.

The Fund also may purchase other types of securities, for example: American
Depository Receipts (ADRs), Global Depository Receipts (GDRs), European Deposi-
tory Receipts (EDRs), and certain derivatives (investments whose value is based
on indices or other securities).

In abnormal market conditions, the Fund may take temporary defensive measures--
such as holding unusually large amounts of cash and cash equivalents--that are
inconsistent with the Fund's primary investment strategy. In taking those mea-
sures, the Fund may not achieve its investment goal.

MAIN RISKS

Primary

Foreign Risk: The Fund's foreign securities will pose special risks, due to
limited government regulation, lack of public information, economic, political
and social instability and foreign currency rate fluctuations. Factors such as
lack of liquidity, foreign ownership limits and restrictions on removing cur-
rency also pose special risks. All foreign securities have some degree of for-
eign risk. However, to the extent the Fund invests in emerging market coun-
tries,
it will have a significantly higher degree of foreign risk than if it invested
exclusively in developed or newly-industrialized countries.

Market Risk: The value of the securities in the Fund may go down in response
to overall stock or bond market movements. Markets tend to move in cycles,
with periods of rising prices and periods of falling prices. Stocks tend to go
up and down in value more than bonds. If the Fund's investments are concen-
trated in certain sectors, the Fund's performance could be worse than the

Emerging Markets Equity Fund

GOAL AND STRATEGY

This is an emerging markets stock fund that seeks long-term growth in capital.

The Fund invests primarily in the stocks of companies in countries having econ-
omies or markets generally considered by the World Bank or United Nations to be
emerging or developing.

In making country allocation decisions, the manager analyzes the global envi-
ronment and selects countries with:

 . Improving macroeconomic, political and social trends, and

 . attractive valuation levels.

The manager selects stocks using fundamental proprietary research to identify
companies:

 . having strong earnings growth potential,

 . selling below their intrinsic value, and

 . having shareholder-focused management, dominant products, and well estab-
  lished distribution channels.

The Fund normally invests:

 . in at least 15 emerging market countries, and

 . no more than 30% of its assets in any single country.

The Fund normally invests in 100 to 250 stocks in 20 to 25 countries. The Fund
normally has 10% or less of its assets in cash and cash equivalents.

Although the Fund may employ foreign currency hedging techniques, the Fund
normally maintains the currency exposure of the underlying equity investments.

The Fund may purchase other types of securities, for example: American Deposi-
tory Receipts (ADRs), Global Depository Receipts (GDRs), European Depository
Receipts (EDRs), and certain derivatives (investments whose value is based on
indices or other securities).

In abnormal market conditions, the Fund may take temporary defensive measures--
such as holding unusually large amounts of cash and cash equivalents--that are
inconsistent with the Fund's primary investment strategy. In taking those mea-
sures, the Fund may not achieve its investment goal.

MAIN RISKS

Primary

Foreign Risk: The Fund's foreign securities will pose special risks, due to
limited government regulation, lack of public information, economic, political
and social instability and foreign currency rate fluctuations. Factors such as
lack of liquidity, foreign ownership limits and restrictions on removing cur-
rency also pose special risks. All foreign securities have some degree of for-
eign risk. However, since the Fund invests primarily in emerging market coun-
tries, it will have a significantly higher degree of foreign risk than funds
that invest primarily in developed or newly- industrialized countries.

Market Risk: The value of the securities in the Fund may go down in response to
overall stock or bond market movements. Markets tend to move in cycles, with
periods of rising prices and periods of falling prices. Stocks tend to go up
and down in value more than bonds. If the Fund's investments are concentrated
in certain sectors, the Fund's performance could be worse than the overall mar-
ket.

Manager Risk: The manager and its strategy may fail to produce the intended
results. The Fund could underperform its peers or lose money if the manager's
investment strategy does not perform as expected.

Turnover Risk: In general, the greater the volume of buying and selling by a
fund (i.e., the higher its "turnover rate"), the greater the impact that bro-
kerage commissions and other transaction costs will have on the funds perfor-
mance. Any turnover rate in excess of 100% is considered relatively high. The
Fund's turnover rate could be greater than 100% due to the relatively high vol-
atility associated with investing in emerging markets.

Secondary

Derivatives Risk: Certain derivative instruments (such as options, futures and
swaps) can produce disproportionate gains or losses. They are generally consid-
ered more risky than direct equity investments. Also, in a down market, deriva-
tives could become harder to value or sell at a fair price.

Short-Term Bond Fund

GOAL AND STRATEGY

This is a short-term bond fund that seeks high income consistent with low share
price fluctuation.

The Fund primarily invests in a diversified mix of short-term and intermediate-
term investment grade debt securities including:

 . U.S. Treasury and Agency securities;

 . U.S. corporate bonds;

 . foreign corporate bonds of companies in developed countries (if dollar-
  denominated);

 . foreign government and agency securities of developed countries (if dollar
  denominated); and

 . mortgage-and asset-backed securities.

The manager selects bonds using a combination of proprietary research and quan-
titative tools. Bonds are purchased that are attractively priced and that pro-
vide cheap, predictable cash flows.

The Fund normally invests:

 . mostly in corporate bonds;

 . no more than 15% of its assets in high yield bonds; and

 . no more than 25% of its assets in foreign debt securities.

The Fund normally has:

 . an average maturity between one and three and a half years;

 . an average credit quality rating of "A" or higher; and

 . 10% or less of its assets in cash and cash equivalents.

The Fund only invests in securities that are rated at least BB- or Ba3 at time
of purchase.

The Fund may purchase other types of securities, for example: certain deriva-
tives (investments whose value is based on indexes or other securities).

In abnormal market conditions, the Fund may take temporary defensive measures--
such as holding unusually large amounts of cash and cash equivalents--that are
inconsistent with the Fund's primary investment strategy. In taking those mea-
sures, the Fund may not achieve its investment goal.

MAIN RISKS

Primary

Market Risk: The value of the securities in the Fund may go down in response
to overall stock or bond market movements. Markets tend to move in cycles,
with periods of rising prices and periods of falling prices. Stocks tend to go
up and down in value more than bonds. If the Fund's investments are concen-
trated in certain sectors, the Fund's performance could be worse than the
overall market.

Manager Risk: The manager and its strategy may fail to produce the intended
results. The Fund could underperform its peers or lose money if the manager's
investment strategy does not perform as expected.

Interest Rate Risk: When interest rates rise, the Fund's bond yields will gen-
erally rise and the Fund's bond prices will generally fall. When interest
rates fall, the reverse will generally occur. The longer the average remaining
maturity of bonds held by the Fund, the more sensitive the Fund is to interest
rate risk. This Fund has less interest rate risk than an intermediate-term or
long-term bond fund.
Credit Risk: An issuer of a bond held by the Fund may default on its obliga-
tion to pay interest and repay principal. Also, the credit rating of a bond
held by the fund may be downgraded. In either case, the value of the bond held
by the Trust would fall. All bonds have some credit risk, but in general low-
er-rated bonds have higher credit risk.

Concentration Risk: The Fund's investment in securities of a smaller number of
issuers could produce more volatile performance relative to funds that invest
in a larger number of issuers. The more concentrated a fund's holdings are,
the more likely it is a specific security's poor performance will hurt the
fund significantly.

Turnover Risk: In general, the greater the volume of buying and selling by a
fund (i.e., the higher its "turnover rate"), the greater the impact that bro-
kerage commissions and other transaction costs will have on the fund's perfor-
mance. Any turnover rate in excess of 100% is considered relatively high. Nor-
mally, the Fund's turnover rate will be greater than 100%.
Secondary

Foreign Risk: The Fund's foreign securities will pose special risks, due to
limited government regulation, lack of public information, and economic,
political and social instability. Factors such as lack of liquidity, foreign
ownership limits and restrictions on removing currency also pose special
risks.

Derivatives Risk: Certain derivative instruments (such as options, futures and
swaps) can produce disproportionate gains or losses. They are generally con-
sidered more risky than direct equity investments. Also, in a down market,
derivatives could become harder to value or sell at a fair price.

High Yield Bond Risk: Junk bonds, defined as bond securities rated below BBB-
/Baa3, may be subject to more volatile or erratic price movements due to
investor sentiment. In a down market, these high yield securities become
harder to value or to sell at a fair price.

Prepayment / Call Risk: The Fund's share price or yield could be hurt if
interest rate movements cause the Fund's mortgage-related and callable securi-
ties to be paid off substantially earlier than expected.

Bond Index Fund

GOAL AND STRATEGY

This is a bond fund that seeks to track the performance of the Lehman Brothers
Government / Corporate Bond Index.

The manager employs a passive management strategy using quantitative techniques
to select individual securities that provide a representative sample of the
securities in the Index.

If the Fund reaches approximately $50 million in total assets, the manager will
seek to match the performance of the Lehman Brothers Aggregate Bond Index, a
broader market index that also includes mortgage-backed and asset-backed secu-
rities.

Both of these Indexes consist of dollar-denominated investment grade securities
with maturities greater than one year and outstanding par values of at least
$150 million issued primarily by:

 . the U.S. Treasury and U.S. government agencies and instrumentalities;

 . foreign governments and agencies; and

 . U.S. and foreign corporations.

The manager selects securities to match, as closely as practical, the Index's
duration, cash flow, sector, credit quality, callability, and other key perfor-
mance characteristics. The Fund may hold some cash and cash equivalents, but is
normally fully invested.
The Index composition may change from time to time. The manager may keep secu-
rities that no longer meet the Index criteria as long as:

 . such "ineligible" securities plus cash and money market instruments are less
  than 20% of the Fund's assets; and

 . high yield securities are less than 5% of the Fund's assets.

MAIN RISKS

Primary

Index Management Risk:  Certain factors such as the following may cause the
Fund to track the Index less closely:

 . The securities selected by the manager may not be fully representative of the
  Index.

 . Transaction expenses of the Fund may result in the Fund's performance being
  different than that of the Index.

 . The size and timing of the Fund's cash flows may result in the Fund's perfor-
  mance being different than that of the Index.

Also, index funds like this one will have more difficulty in taking defensive
positions in abnormal market conditions.

Market Risk: The value of the securities in the Fund may go down in response to
overall stock or bond market movements. Markets tend to move in cycles, with
periods of rising prices and periods of falling prices. Stocks tend to go up
and down in value more than bonds. If the Fund's investments are concentrated
in certain sectors, the Fund's performance could be worse than the overall mar-
ket.

Manager Risk: The manager and its strategy may fail to produce the intended
results. The Fund could underperform its peers or lose money if the manager's
investment strategy does not perform as expected.

Interest Rate Risk: When interest rates rise, the Fund's bond yields will gen-
erally rise and the Fund's bond prices will generally fall. When interest rates
fall, the reverse will generally occur. The longer the average remaining matu-
rity of bonds held by the Fund, the more sensitive the Fund is to interest rate
risk. This Fund has more interest rate risk than a short-term bond fund, but
less interest rate risk than a long-term bond fund.

Credit Risk: An issuer of a bond held by the Fund may default on its obligation
to pay interest and repay principal. Also, the credit rating of a bond held by
the fund may be downgraded. In either case, the value of the bond held by the
Trust would fall. All bonds have some credit risk, but in general lower-rated
bonds have higher credit risk.

Secondary

Foreign Risk: The Fund's foreign securities will pose special risks, due to
limited government regulation, lack of public information, and economic, polit-
ical and social instability. Factors such as lack of liquidity, foreign owner-
ship limits and restrictions on removing currency also pose special risks. All
foreign securities have some degree of foreign risk. However, to the extent the
Fund invests in emerging market countries, it will have a significantly higher
degree of foreign risk than if it invested exclusively in developed or newly-
industrialized countries.

Active Bond Fund
(Formerly Sovereign Bond Fund)

GOAL AND STRATEGY

This is a bond fund that seeks income and growth in capital.

The Fund primarily invests in a diversified mix of debt securities including:

 . U.S. Treasury and agency securities;

 . foreign government and agency securities (if dollar-denominated);

 . corporate bonds, both U.S. and foreign (if dollar-denominated); and

 . mortgage-backed and asset-backed securities.

The manager normally invests:

 . mostly in investment grade debt securities;

 . no more than 25% of the Fund's assets in high yield bonds; and

 . no more than 25% of the Fund's assets in foreign securities, excluding Cana-
  dian securities.

The manager seeks to identify specific bond sectors, industries and specific
bonds that are attractively priced. The manager tries to anticipate shifts in
the business cycle, using economic and industry analysis to determine which
sectors and industries might benefit over the next 12 months. The manager uses
proprietary research to identify securities that are undervalued.

The manager evaluates bonds of all quality levels and maturities from many dif-
ferent issuers. The Fund normally has an average credit rating A or higher.

The Fund normally has 10% or less of its assets in cash and cash equivalents.
The Fund may purchase other types of securities, for example: emerging market
debt securities, and certain derivatives (investments whose value is based on
indices or other securities). The manager actively uses derivatives, such as
futures, to adjust the Fund's average maturity relative to the
Lehman Brothers Aggregate Bond Index and seeks to keep the Fund's interest rate
sensitivity in line with the overall market.

In abnormal market conditions, the Fund may take temporary defensive measures--
such as holding unusually large amounts of cash and cash equivalents--that are
inconsistent with the Fund's primary investment strategy. In taking those mea-
sures, the Fund may not achieve its investment goal.

MAIN RISKS

Primary

Market Risk: The value of the securities in the Fund may go down in response
to overall stock or bond market movements. Markets tend to move in cycles,
with periods of rising prices and periods of falling prices. Stocks tend to go
up and down in value more than bonds. If the Fund's investments are concen-
trated in certain sectors, the Fund's performance could be worse than the
overall market.

Manager Risk: The manager and its strategy may fail to produce the intended
results. The Fund could underperform its peers or lose money if the manager's
investment strategy does not perform as expected.

Interest Rate Risk: When interest rates rise, the Fund's bond yields will gen-
erally rise and the Fund's bond prices will generally fall. When interest
rates fall, the reverse will generally occur. The longer the average remaining
maturity of bonds held by the Fund, the more sensitive the Fund is to interest
rate risk. This Fund has more interest rate risk than a short-term bond fund,
but less interest rate risk than a long-term bond fund.

Credit Risk: An issuer of a bond held by the Fund may default on its obliga-
tion to pay interest and repay principal. Also, the credit rating of a bond
held by the fund may be downgraded. In either case, the value of the bond held
by the Fund would fall. All bonds have some credit risk, but in general lower-
rated bonds have higher credit risk.
Turnover Risk: In general, the greater the volume of buying and selling by a
fund (i.e., the higher its "turnover rate"), the greater the impact that bro-
kerage commissions and other transaction costs will have on the fund's perfor-
mance. Any turnover rate in excess of 100% is considered relatively high. Nor-
mally, the Fund's turnover rate will be greater than 100%.

Secondary

Foreign Risk: The Fund's foreign securities will pose special risks, due to
limited government regulation, lack of public information, and economic,
political and social instability. Factors such as lack of liquidity, foreign
ownership limits and restrictions on removing currency also pose special
risks. All foreign securities have some degree of foreign risk. However, to
the extent the Fund invests in emerging market countries, it will have a sig-
nificantly higher degree of foreign risk than if it invested exclusively in
developed or newly-industrialized countries.

Derivatives Risk: Certain derivative instruments (such as options, futures and
swaps) can produce disproportionate gains or losses. They are generally con-
sidered more risky than direct equity investments. Also, in a down market,
derivatives could become harder to value or sell at a fair price.

High Yield Bond Risk: Junk bonds, defined as bond securities rated below BBB-
/Baa3, may be subject to more volatile or erratic price movements due to
investor sentiment. In a down market, these high yield securities become
harder to value or to sell at a fair price.

Prepayment/Call Risk: The Fund's share price or yield could be hurt if inter-
est rate movements cause the Fund's mortgage-related and callable securities
to be paid off substantially earlier than expected.

Global Bond Fund

GOAL AND STRATEGY

This is a global bond fund that seeks income and growth in capital.

The Fund primarily invests in a mix of debt securities of developed countries
throughout the world including:

 . U.S. Treasury and agency securities;

 . foreign government and agency securities;

 . supranational securities (such as the World Bank);

 . corporate bonds, both U.S. and foreign; and

 . mortgage-backed and asset-backed securities.

The manager makes ongoing decisions regarding the Fund's mix of U.S. bonds and
non-U.S. bonds (denominated in foreign currencies). The manager has a target
mix of 35% U.S. bonds and 65% non-U.S. bonds, but actively manages the mix
within (+/-) 50 percentage points of the target mix.

The Fund invests in at least 3 countries, but normally in 5 to 15 countries.
The Fund normally has an average credit quality rating of "AA" or higher.

The manager makes ongoing decisions regarding the Fund's average maturity,
country and sector allocations and foreign currency exposures. The manager uses
proprietary research and economic analysis to try to anticipate market condi-
tions and interest rate movements and to purchase securities that appear com-
paratively undervalued.

The manager actively uses derivatives (investments whose value is based on
indices or other securities) such as futures, forwards, options and swaps to
adjust the Fund's average maturity and to implement currency strategies. The
Fund is typically 75% to 100% hedged to the U.S. dollar.

The manager actively uses cash and cash equivalents to manage the Fund's aver-
age maturity. However, the Fund normally invests 20% or less of its assets in
cash and cash equivalents.

The Fund may purchase other types of securities, for example: high yield debt
securities and emerging market debt securities.

In abnormal market conditions, the Fund may take temporary defensive measures--
such as holding unusually large amounts of cash and cash equivalents--that are
inconsistent with the Fund's primary investment strategy. In taking those mea-
sures, the Fund may not achieve its investment goal.

MAIN RISKS

Primary

Foreign Risk: The Fund's foreign securities will pose special risks, due to
limited government regulation, lack of public information, economic, political
and social instability and foreign currency rate fluctuations. Factors such as
lack of liquidity, foreign ownership limits and restrictions on removing cur-
rency also pose special risks. All foreign securities have some degree of for-
eign risk. However, the Fund's investments in emerging market countries have a
significantly higher degree of foreign risk than investments in developed or
newly-industrialized countries.

Market Risk: The value of the securities in the Fund may go down in response to
overall stock or bond market movements. Markets tend to move in cycles, with
periods of rising prices and periods of falling prices. Stocks tend to go up
and down in value more than bonds. If the Fund's investments are concentrated
in certain sectors, the Fund's performance could be worse than the overall mar-
ket.

Manager Risk: The manager and its strategy may fail to produce the intended
results. The Fund could underperform its peers or lose money if the manager's
investment strategy does not perform as expected.

Interest Rate Risk: When interest rates rise, the Fund's bond yields will gen-
erally rise and the Fund's bond prices will generally fall. When interest rates
fall, the reverse will generally occur. The longer the average remaining matu-
rity of bonds held by the Fund, the more sensitive the Fund is to interest rate
risk. This Fund has more interest rate risk than a short-term bond fund, but
less interest rate risk than a long-term bond fund.

Credit Risk: An issuer of a bond held by the Fund may default on its obligation
to pay interest and repay principal. Also, the credit rating of a bond held by
the fund may be downgraded. In either case, the value of the bond held by the
Trust would fall. All bonds have some credit risk, but in general lower-rated
bonds have higher credit risk.

Concentration Risk: The Fund's investment in securities of a smaller number of
issuers could produce more volatile performance relative to funds that invest
in a larger number of issuers. The more concentrated a fund's holdings are, the
more likely it is a specific securities poor performance will hurt the fund
significantly.

Turnover Risk: In general, the greater the volume of buying and selling by a
fund (i.e., the higher its "turnover rate"), the greater the impact that bro-
kerage commissions and other transaction costs will have on the fund's perfor-
mance. Any turnover rate in excess of 100% is considered relatively high. Nor-

ered more risky than direct equity investments. Also, in a down market, deriva-
tives could become harder to value or sell at a fair price.

High Yield Bond Fund

GOAL AND STRATEGY

This is a high yield bond fund that seeks high income and growth in capital.

The Fund invests primarily in a diversified mix of high yield debt securities,
commonly referred to as "junk bonds" (rated BB+/Ba1 or lower and their unrated
equivalents), including:

 . corporate bonds, both U.S. and foreign (if dollar-denominated);

 . foreign government and agency securities (if dollar-denominated);

 . preferred stocks; and

 . convertible securities (convertible into common stocks or other equity inter-
  ests).

The manager will invest no more than 15% of the Fund's assets in emerging mar-
ket countries (with below investment-grade sovereign debt). The Fund normally
has 10% or less of its assets in cash and cash equivalents.

The manager seeks to purchase bonds with stable or improving credit quality
before the market widely perceives the improvement. Purchase and sale decisions
are primarily based upon the investment merits of the particular security.

The manager selects bonds using proprietary research, including:

 . quantitative analysis of historical financial data;

 . qualitative analysis of a company's future prospects; and

 . economic and industry analysis.

The Fund's average maturity depends on security selection decisions rather than
interest rate decisions.

The Fund may purchase other types of securities, for example: equity securi-
ties, high quality debt securities (short-term and otherwise), certain deriva-
tives (investments whose value is based on indices or other securities), and
debt securities denominated in foreign currencies.

In abnormal market conditions, the Fund may take temporary defensive measures--
such as holding unusually large amounts of cash and cash equivalents--that are
inconsistent with the Fund's primary investment strategy. In taking those mea-
sures, the Fund may not achieve its investment goal.

PAST PERFORMANCE

The graph will show how the fund's total return varies from year to year, while
the table will show performance over time (along with a broad-based market
index for reference). This information may help provide an indication of the
fund's risks and potential rewards. All figures assume dividend reinvestment.
Past performance does not indicate future results. The performance figures
below do not reflect the deduction of fees and charges payable under the
variable contracts. Such fees and charges would cause the investment returns
under the contracts to be less than that shown below.

MAIN RISKS

Primary

High Yield Bond Risk: High yield or junk bonds, defined as bond securities
rated below BBB-/Baa3, may be subject to more volatile or erratic price move-
ments due to investor sentiment. In a down market, these high yield securities
may become harder to value or to sell at a fair price.

Market Risk: The value of the securities in the Fund may go down in response to
overall stock or bond market movements. Markets tend to move in cycles, with
periods of rising prices and periods of falling prices. Stocks tend to go up
and down in value more than bonds. If the Fund's investments are concentrated
in certain sectors, the Fund's performance could be worse than the overall mar-
ket.

Manager Risk: The manager and its strategy may fail to produce the intended
results. The Fund could underperform its peers or lose money if the manager's
investment strategy does not perform as expected.
Interest Rate Risk: When interest rates rise, the Fund's bond yields will gen-
erally rise and the Fund's bond prices will generally fall. When interest rates
fall, the reverse will generally occur. The longer the average remaining matu-
rity of bonds held by the Fund, the more sensitive the Fund is to interest rate
risk. This Fund has more interest rate risk than a short-term bond fund, but
less interest rate risk than a long-term bond fund.

Credit Risk: An issuer of a bond held by the Fund may default on its obligation
to pay interest and repay principal. Also, the credit rating of a bond held by
the fund may be downgraded. In either case, the value of the bond held by the
Fund would fall. All bonds have some credit risk, but in general lower-rated
bonds have higher credit risk.

Secondary

Foreign Risk: The Fund's foreign securities will pose special risks, due to
limited government regulation, lack of public information, and economic, polit-
ical and social instability. Factors such as lack of liquidity, foreign owner-
ship limits and restrictions on removing currency also pose special risks. All
foreign securities have some degree of foreign risk. However, to the extent the
Fund invests in emerging market countries, it will have a significantly higher
degree of foreign risk than if it invested exclusively in developed or newly-
industrialized countries.

Derivatives Risk: Certain derivative instruments (such as options, futures and
swaps) can produce disproportionate gains or losses. They are generally consid-
ered more risky than direct equity investments. Also, in a down market, deriva-
tives could become harder to value or sell at a fair price.

Prepayment/Call Risk: The Fund's share price or yield could be hurt if interest
rate movements cause the Fund's mortgage-related and callable securities to be
paid off substantially earlier than expected.

Money Market Fund

GOAL AND STRATEGY

This is a money market fund that seeks current income consistent with maintain-
ing liquidity and preserving capital. The Fund intends to maintain a stable net
asset value of $10 per share.

The Fund only invests in U.S. dollar denominated money market instruments rated
within the two highest short-term credit rating categories, primarily includ-
ing:

 . commercial paper;

 . asset-backed commercial paper;

 . bank notes and certificates of deposit;

 . short-term bonds;

 . U.S. Treasury and agency notes and bills; and

 . repurchase and reverse repurchase agreements.

These securities have a maximum remaining maturity of 397 days (13 months) and
may be issued by:

 . U.S. and foreign banks and other lending institutions;

 . U.S. and foreign corporations;

 . the U.S. Treasury and U.S. government agencies and instrumentalities;

 . entities whose obligations are guaranteed as to principal or interest by the
  U.S. Government;

 . municipalities;

 . foreign governments; and

 . supranational organizations (such as the World Bank).

The weighted average time to maturity of the Fund's investments is 90 days or
less.

The manager may invest:

 . up to 5% of assets in securities rated in the second-highest short-term cate-
  gory (or unrated equivalents); and

 . up to 1% of assets or $1 million (whichever is greater) in securities of a
  single issuer rated in the second-highest short-term category (or unrated
  equivalents).

The manager selects securities with the highest yield available among securi-
ties of comparable credit quality and maturity using proprietary research.

Your Account

Investments in shares of the funds

Each fund sells its shares directly to separate accounts of John Hancock,
JHVLICO and IPL to fund variable contracts. Each fund also buys back its shares
on redemption by the separate accounts.

Under the variable contracts, a separate account buys or redeems a fund's
shares based on:

 . instructions by you and other contractowners to invest or receive back monies
  under a contract (such as making a premium payment or surrendering a con-
  tract), and

 . the operation of a contract (such as deduction of fees and charges).

The Trust, as law permits, may:

 . refuse a buy order if the adviser believes it would disrupt management

 . suspend a fund's offer of shares, or

 . suspend a fund's redemption obligation or postpone a fund's payment of
  redemption proceeds for more than seven days.

Share price

Each fund sells and buys back its shares at the net asset value per share
("NAV") next computed after receipt by a separate account of a contractowner's
instructions.

Each fund calculates its NAV:

 . by dividing its net assets by the number of its outstanding shares,

 . once daily as of the close of regular trading on the New York Stock Exchange
  (generally at 4 p.m. New York time) on each day the Exchange is open.

Certain funds may hold securities primarily listed on foreign exchanges that
trade on weekends or other days when the Trust does not calculate NAV. Conse-
quently, NAV may change on days when contractowners will not be able to
instruct a separate account to buy or redeem fund shares.

Valuation

The Money Market Fund values its securities at amortized cost. Each of the
other funds values securities based on:

 . market quotations,

 . amortized cost,

 . valuations of independent pricing services, or

 . fair value determined in accordance with procedures approved by the Trust's
  trustees.

A fund may value securities at fair value where, for example:

 .market quotations are not readily available, or

 . the value of securities has been materially affected after the closing of a
  foreign market.

Conflicts

The Trust's trustees monitor for possible material irreconcilable conflicts
among separate accounts buying shares of the funds. The Trust's net asset value
could decrease, if the Trust had to sell investment securities to pay redemp-
tion proceeds to a separate account withdrawing because of a conflict.

The adviser pays subadvisory fees out of its own assets. No fund pays a fee to
its subadviser.

The adviser has agreed to limit each fund's annual expenses (excluding advisory
fees and certain other expenses such as brokerage and taxes) to not more than
 .10 percent of the fund's average daily net assets.
Dividends and Taxes

Dividends

Each fund automatically reinvests its dividends and distributions in additional
shares of the fund at NAV.

Each fund declares and pays dividends monthly, except that the Money Market
Fund does so daily.

Funds generally declare capital gains distributions annually.

Taxes

Each fund must meet investment diversification and other requirements under the
Internal Revenue Code, in order to:

 . avoid federal income tax and excise tax, and

 . assure the tax-deferred treatment of variable contracts under the Code.

You should read the prospectus for your variable contract for the federal
income tax consequences for contractowners, including the consequences of a
fund's failure to meet Code requirements.

APPENDIX

Additional Performance Information

The "Past Performance" information shown earlier in this prospectus for certain
of the Funds may not be sufficient for you to make a complete assessment of the
risks and potential rewards of investing in those Funds. The Small/Mid Cap CORE
Fund, the Emerging Markets Equity Fund, the Bond Index Fund, and the High Yield
Bond Fund only began operations on May 1, 1998. The Small/Mid Cap Growth Fund
and the Global Bond Fund each implemented a significant change in strategy as
of May 1, 1999. Finally, the Global Balanced Fund implemented a significant
change in strategy as of May 1, 2000.

Since each of these Funds has at best a very limited period of relevant perfor-
mance history, we have set forth below information for certain similar accounts
that are managed by the Funds' respective subadvisers. Each grouping of such
accounts is referred to as a "composite." In the case of each account included
in a composite, the total management fees and other operating expenses of the
Fund (based upon management fee schedules and allocation rules currently in
effect) have been substituted for the actual fees and expenses (other than bro-
kerage and other transaction expenses) of the account. Also, except as specifi-
cally noted below, each composite includes all of the investment company and
other accounts of the subadviser that satisfy the following requirements:

 . they have been managed with investment objectives, policies, and strategies
  substantially similar to those used in managing the Fund, and

 . they are of sufficient size that their performance would be considered rele-
  vant to the owner of a variable contract investing in that Fund.

Some of the accounts in the composites were not registered investment companies
and, therefore, were not subject to federal income tax and other legal require-
ments applicable to such companies. Had such accounts been subject to such
requirements, their performance could have been adversely affected. The perfor-
mance figures in this Appendix do not reflect the deduction of fees and charges
payable under the variable contracts. Such fees and charges would cause the
investment returns under the contacts to be less than that shown below.

The graphs below show how the composite's total return has varied from year to
year, while the tables show performance over time (along with a broad-based
index for reference). All figures assume dividend reinvestment. Past perfor-
mance does not indicate future results.

Overview

- --------------------------------------------------------------------------------
FUND INFORMATION KEY
Concise fund-by-fund descriptions begin on page 6. Each description provides
the following information:

Goal and Strategy The fund's particular investment goals and the principal
strategies it intends to use in pursuing those goals.

Subadviser/Manager The firm and individual(s) providing investment management
services to the fund.

Past Performance The fund's total return, measured year-by-year and over time.

Main Risks The significant risk factors associated with the fund. The risks are
categorized as "Primary" or "Secondary". The Primary Risks are considered major
factors in the fund's performance and are described first. The Secondary Risks
are not considered major factors in the fund's performance because the fund
would not normally commit a large portion of its assets to the investments
involved. However, the Secondary Risks are of such a nature that they could
significantly affect the fund's performance, even if the investments are held
in relatively small amounts.

Financial Highlights The fund's operating performance per share, measured year-
by-year.
THE FUNDS
The Trust offers investment choices, or funds, for the variable annuity and
variable life insurance contracts ("variable contracts") of:

 . John Hancock Life Insurance Company ("John Hancock"),

 . John Hancock Variable Life Insurance Company ("JHVLICO"), and

 . Investors Partner Life Insurance Company and its subsidiaries ("IPL").

In some variable contract forms, the Trust is referred to as the "Fund" or "Se-
ries Fund" and the investment choices are referred to as "Portfolios."

RISKS OF FUNDS
These funds, like all mutual funds, are not bank deposits. They are not insured
or guaranteed by the FDIC or any other government agency. You could lose money
by investing in these funds. So, be sure to read all risk disclosure carefully
before investing.

MANAGEMENT
John Hancock is the investment adviser of each fund. John Hancock is a Massa-
chusetts stock life insurance company. On February 1, 2000, John Hancock
changed its form of organization and its name. Prior to that date, it was John
Hancock Mutual Life Insurance Company, a mutual life insurance company that was
chartered in 1862. At the end of 1999, John Hancock managed approximately $127
billion, of which it owned over
$71 billion. Most of the funds have subadvisers.

Your Investment Choices

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

The Trust offers a number of investment choices, or funds, to suit a variety
of objectives under variable contracts. There are 23 funds available under
your variable contract. Each fund has its own strategy and its own risk/reward
profile.The funds can be broadly categorized as equity funds, balanced funds,
bond funds, and international/global funds. Within these broad categories, the
funds can be further categorized as follows:

Equity Funds
Equity funds can be categorized in two ways--by capitalization and by invest-
ment style.

Capitalization              Equity funds can be categorized by market capital-
                            ization, which is defined as the market value of
                            all shares of a company's stock. The following def-
                            initions for large, mid and small cap are based
                            upon statistics at year-end 1999, but are adjusted
                            periodically with broad equity market movements as
                            represented by the Russell 3000 Index(R) or other
                            widely-recognized source of market capitalization
                            data. Adjustments are typically made on a quarterly
                            basis, but in extraordinary circumstances may be
                            made as frequently as monthly.

                            Large Cap Funds:
 . Growth & Income Fund      These funds invest in large, well-established com-
                            panies that typically are very actively traded and
 . Equity Index Fund         provide more stable investment returns over time.
                            Large cap companies represent the 300 largest
 . Large Cap Value Fund      stocks in the Russell 3000 Index. Each of those
                            companies has a market capitalization greater than
 . Large Cap Growth Fund     $7.9 billion as of the end of 1999. Large cap funds
                            are appropriate for investors who want the least
 . Large Cap Aggressive      volatile investment returns within the overall
  Growth                    equity markets.


                            Mid Cap Funds:
 . Mid Cap Value Fund        These funds invest in medium-sized, less estab-
                            lished companies that are less actively traded and
 . Mid Cap Growth Fund       provide more share price volatility over time than
                            large cap stocks. Mid cap companies represent the
 . Fundamental Mid Cap       250th to 1000th largest stocks in the Russell 3000
  Growth                    Index. Each of those companies has a market capi-
                            talization between $1.4 billion and $9.7 billion as
 . Small/Mid Cap CORE Fund   of the end of 1999. Mid cap funds are appropriate
                            for investors who are willing to accept more vola-
 . Small Mid/Cap Growth      tile investment returns within the overall equity
  Fund                      markets with the potential reward of higher long-
                            term returns.
 . Real Estate Equity Fund


                            Small Cap Funds:
 . Small Cap Value Fund      These funds invest in small newly established com-
                            panies that are less actively traded and have a
 . Small Cap Growth Fund     high level of share price volatility over time.
                            Small cap companies represent the 2000 smallest
                            stocks in the Russell 3000 Index. Each of those
                            companies has a market capitalization of less than
                            $1.4 billion as of the end of 1999. Small cap funds
                            are appropriate for investors who are willing to
                            accept the most volatile investment returns within
                            the overall equity markets for the potential reward
                            of higher long-term returns.

Investment Style

                            Value Funds:
 . Large Cap Value Fund      Value funds invest in companies that are attrac-
                            tively priced, considering their asset and earnings
 . Mid Cap Value Fund        history. These stocks typically pay above average
                            dividends and have low stock prices relative to
 . Small Cap Value Fund      measures of earnings and book value. Value funds
                            are appropriate for investors who want some divi-
 . Real Estate Equity Fund   dend income and the potential for capital gains,
                            but are less tolerant of share-price fluctuations.



                                                                              3
<PAGE>

                           Growth Funds:
 . Large Cap Growth Fund    Growth funds invest in companies believed to have
                           above-average prospects for capital growth due to
 . Large Cap Agressive      their strong earnings and revenue potential. Growth
  Growth                   stocks typically have high stock prices relative to
                           measures of earnings and book value. Growth funds
 . Mid Cap Growth Fund      are appropriate for investors who are willing to
                           accept more share-price volatility for the poten-
 . Fundamental Mid/Cap      tial reward of higher long-term returns.
  Growth Fund

 . Small Mid/Cap Growth     Blend Funds:
  Fund                     Blend funds invest in both value and growth compa-
                           nies. Blend funds are appropriate for investors who
 . Small Cap Growth Fund    seek both dividend and capital appreciation charac-
                           teristics.
 . Growth & Income Fund

 . Equity Index Fund

 . Small/Mid Cap CORE
  Fund

Balanced Funds

 . Managed Fund             Balanced funds invest in a combination of stocks
                           and bonds and actively manage the mix of stock and
 . Global Balanced          bonds within a target range. Domestic balanced
  Fund                     funds invest in U.S. stocks and bonds. Interna-
                           tional balanced funds invest in foreign stocks and
                           bonds.

Bond Funds
Bond funds can be categorized in two ways--by average maturity and by credit
quality:

Average Maturity           Bond maturity is a key measure of interest rate
                           risk. A bond's maturity measures the time remaining
                           until the bond matures, or until the repayment of
                           the bond's principal comes due. The longer a bond's
                           maturity, the more sensitive the bond's price is to
                           changes in interest rates.

                           Short:
 . Money Market Fund        These funds invest primarily in bonds with short
                           maturities, typically less than four years. These
 . Short Term Bond          funds have less interest risk than intermediate-
  Fund                     term bond funds.


                           Intermediate:
 . Bond Index Fund          These funds invest in bonds of all maturities and
                           maintain an average maturity which is typically
 . Active Bond Fund         between four and ten years. These funds have more
                           interest rate risk than short-term bond funds.
 . Global Bond Fund

 . High Yield Bond Fund


Credit Quality             Credit quality is a measure of the ability of a
                           bond issuer to meet its financial obligations and
                           repay principal and interest. High quality bonds
                           have less credit risk than lower quality bonds.
                           Investment grade bonds typically have "high" or
                           "medium" credit quality ratings (as defined below),
                           while high-yield bonds have "low" credit quality
                           ratings.

                           High:
 . Money Market Fund        These funds focus on the highest-rated, most
                           creditworthy bonds and typically maintain an aver-
 . Bond Index Fund          age credit quality rating of AAA/Aaa or AA/Aa.

 . Global Bond Fund

<PAGE>

                           Medium:
 . Short Term Bond Fund     These funds invest in bonds of all credit quality
                           levels with a focus on high-rated investment grade
 . Active Bond Fund         bonds. These funds typically maintain an average
                           credit quality rating of A or BBB/Baa.

                           Low:
 . High Yield Bond Fund     These funds invest primarily in lower rated bonds--
                           known as high yield or "junk" bonds. These funds
                           typically maintain a below investment-grade average
                           credit quality rating of BB/Ba or B.


International/Global Funds
International funds invest primarily in securities markets outside the United
States. Global funds invest both in the United States and abroad. These funds
can be categorized by the types of markets they invest in.

                           Developed Markets:
 . Global Equity Fund       These funds invest primarily in the larger, well-
                           established developed or industralized markets
 . International            around the world. These funds have less foreign
  Equity Index Fund        securities risk than emerging market funds.

 . International
  Opportunities Fund

                           Emerging Markets:
 . Emerging Markets         These funds invest primarily in developing or
  Equity Fund              emerging markets and have more foreign securities
                           risk than funds that invest primarily in well-
                           established, developed markets.

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

In the following pages, any fund investment strategy that is stated as a per-
centage of a fund's assets applies at all times, not just at the time the fund
buys or sells an investment security. The trustees of the Trust can change the
investment goals and stragtegy of any fund without shareholder (i.e.,
contractowner) approval.

The financial highlights tables on the following pages detail the historical
performance of each fund, including total return information showing the
increase or decrease of an investment in the fund each year (assuming rein-
vestment of all dividends and distributions). The "total investment return"
shown for each fund does not reflect the expenses and charges of the applica-
ble separate accounts and variable contracts. Those expenses and charges vary
considerably from contract to contract and are described in the variable con-
tract prospectus to which this prospectus is attached. If the earliest period
shown in the financial highlights table is less than a full calendar year, the
two "Ratios" shown for that period have been annualized (i.e., projected as if
the fund had been in effect for a full year). However, the "total investment
return" and "turnover rate" for that period have not been annualized.

In this prospectus, the term "stock"' is used as a shorthand reference for

Managed Fund

GOAL AND STRATEGY

This is a balanced stock and bond fund that seeks long-term growth in income
and capital.

The Fund invests primarily in a diversified mix of:

 . common stocks of large established U.S. companies;

 . bonds with maturities generally greater than 12 months; and

 . money market and other short-term debt securities with maturities generally
  not greater than 12 months.

The manager makes ongoing decisions about the mix between stocks and bonds. The
Manager has a target mix of 60% in equities and 40% in bonds, but actively man-
ages the mix within (+/-) 10 percentage points of the target mix.

The manager selects stocks and bonds using a combination of proprietary
research and quantitative tools. Stocks are purchased that are undervalued rel-
ative to the stock's history and have improving earnings growth prospects.
Bonds are purchased that are attractively priced and have cheap, predictable
cash flows. The Fund is managed using risk control techniques that maintain
risk and industry characteristics similar to the overall market.

The Fund normally invests its equity portion in 80 to 150 stocks, with at least
65% (usually higher) of its equity assets in large cap companies. The Fund may
invest up to 20% of its bond assets in foreign debt securities of developed
countries (denominated in foreign currencies) and up to 15% of its bond assets
in high yield bonds. The Fund normally has 5% or less of its assets in cash and
cash equivalents.

The Fund may purchase other types of securities, for example: American
Depository Receipts (ADRs), and certain derivatives (investments whose value is
based on indices or other securities). The manager actively uses derivatives,
such as futures and forwards, to adjust the Fund's average maturity relative to
the Lehman Brothers Aggregate Bond Index and to implement currency strategies.

In abnormal market conditions, the Fund may take temporary defensive measures--
such as holding unusually large amounts of cash and cash equivalents--that are
inconsistent with the Fund's primary investment strategy. In taking those mea-
sures, the Fund may not achieve its investment goal.

PAST PERFORMANCE

The graph shows how the fund's total return has varied from year to year, while
the table shows performance over time (along with a broad-based market index
for reference). This information may also help provide an indication of the
fund's risks and potential rewards. All figures assume dividend reinvestment.
Past performance does not indicate future results. The performance figures
below do not reflect the deduction of fees and charges payable under the
variable contracts. Such fees and charges would cause the investment returns
under the contracts to be less than that shown below.

MAIN RISKS
Primary


Market Risk: The value of the securities in the Fund may go down in response
to overall stock or bond market movements. Markets tend to move in cycles,
with periods of rising prices and periods of falling prices. Stocks tend to go
up and down in value more than bonds. If the Fund's investments are concen-
trated in certain sectors, the Fund's performance could be worse than the
overall market.


Manager Risk: The manager and its strategy may fail to produce the intended
results. The Fund could underperform its peers or lose money if the manager's
investment strategy does not perform as expected.


Investment Category Risk: The returns of the Fund's specific equity investment
category may lag the returns of the overall stock market. For example, the
Fund's "large cap" approach carries the risk that in certain markets large cap
stocks will underperform mid cap and small cap stocks.


Interest Rate Risk: When interest rates rise, the Fund's bond yields will gen-
erally rise and the Fund's bond prices will generally fall. When interest
rates fall, the reverse will generally occur. The longer the average remaining
maturity of bonds held by the Fund, the more sensitive the Fund is to interest
rate risk. This Fund has more interest rate risk than a short-term bond fund,
but less interest rate risk than a long-term bond fund.


Credit Risk: An issuer of a bond held by the Fund may default on its obliga-
tion to pay interest and repay principal. Also, the credit rating of a bond
held by the fund may be downgraded. In either case, the value of the bond held
by the Trust would fall. All bonds have some credit risk, but in general low-
er-rated bonds have higher credit risk.


Market Allocation Risk: The allocation of the Fund's assets among major asset
classes (i.e., stocks, bonds, and short-term debt securities) may (1) reduce
the Fund's holdings in a class whose value then increases unexpectedly, or (2)
increase the Fund's holdings in a class just prior to its experiencing a loss
of value.


Turnover Risk: In general, the greater the volume of buying and selling by a
fund (i.e., the higher its "turnover rate"), the greater the impact that bro-
kerage commissions and other transaction costs will have on the fund's perfor-
mance. Any turnover rate in excess of 100% is considered relatively high. Nor-
mally, the Fund's turnover rate will be greater than 100%.
Secondary


Foreign Risk: The Fund's foreign securities will pose special risks, due to
limited government regulation, lack of public information, economic, political
and social instability and foreign currency rate fluctuations. Factors such as
lack of liquidity, foreign ownership limits and restrictions on removing cur-
rency also pose special risks.


Derivatives Risk: Certain derivative instruments (such as options, futures and
swaps) can produce disproportionate gains or losses. They are generally con-
sidered more risky than direct equity investments. Also, in a down market,
derivatives could become harder to value or sell at a fair price.


High Yield Bond Risk: Junk bonds, defined as bond securities rated below BBB-
/Baa3, may be subject to more volatile or erratic price movements due to
investor sentiment. In a down market, these high yield securities become
harder to value or to sell at a fair price.


Prepayment/Call Risk: The Fund's share price or yield could be hurt if inter-
est rate movements cause the Fund's mortgage-related and callable securities
to be paid off substantially earlier than expected.

Growth & Income Fund

GOAL AND STRATEGY

This is a large cap stock fund that seeks long-term growth in income and capi-
tal.

The Fund invests primarily in a diversified mix of common stocks of large
established U.S. companies that are believed to offer:

 . favorable prospects for increasing dividends and growth in capital (i.e.,
  "value" companies); or

 . above-average potential for growth in revenues and earnings (i.e., "growth"
  companies).

The manager selects stocks using a combination of proprietary equity research
and quantitative tools. Stocks are purchased that are undervalued relative to
the stock's history and have improving earnings growth prospects. The Fund is
managed using risk control techniques that maintain risk and industry charac-
teristics similar to the S&P 500 Index.

The Fund normally invests in 80 to 150 stocks, with at least 65% (usually high-
er) of its assets in large cap companies. The Fund normally has 5% or less of
its assets in cash and cash equivalents.

The Fund may purchase other types of securities, for example: American Deposi-
tory Receipts (ADRs).

In abnormal market conditions, the Fund may take temporary defensive measures--
such as holding unusually large amounts of cash and cash equivalents--that are
inconsistent with the Fund's primary investment strategy. In taking those mea-
sures, the Fund may not achieve its investment goal.

Equity Index Fund

GOAL AND STRATEGY

This is a stock fund that seeks to track the performance of the S&P 500 Index,
which emphasizes the stocks of large U.S. companies.

The manager employs a passive management strategy by normally investing in all
500 stocks included in the Index. The manager invests in each stock in roughly
the same proportion as represented in the Index.

The manager seeks to replicate as closely as possible the aggregate risk char-
acteristics and industry diversification of the Index.

The Fund normally invests in all 500 stocks in the Index, but has no predeter-
mined number of stocks that it must hold. S&P may change the composition of the
Index from time to time. The manager will reflect those changes as soon as
practical.

The Fund is normally fully invested. The manager may invest in stock index
futures to maintain market exposure and manage cash flow.

The Fund may purchase other types of securities, for example: Standard & Poor's
Depository Receipts (SPDRs), American Depository Receipts (ADRs), cash equiva-
lents, and certain derivatives (investments whose value is based on indices or
other securities).

MAIN RISKS

Primary

Index Management Risk:  Certain factors such as the following may cause the
Fund to track the Index less closely:

 . The securities selected by the manager may not be fully representative of
  the Index.

 . Transaction expenses of the Fund may result in the Fund's performance being
  different than that of the Index.

 . The size and timing of the Fund's cash flows may result in the Fund's per-
  formance being different than that of the Index.
Also, index funds like this one will have more difficulty in taking defensive
positions in abnormal market conditions.

Market Risk: The value of the securities in the Fund may go down in response
to overall stock or bond market movements. Markets tend to move in cycles,
with periods of rising prices and periods of falling prices. Stocks tend to go
up and down in value more than bonds. If the Fund's investments are concen-
trated in certain sectors, the Fund's performance could be worse than the
overall market.

Manager Risk: The manager and its strategy may fail to produce the intended
results. The Fund could underperform its peers or lose money if the manager's
invest-ment strategy does not perform as expected.

Investment Category Risk: The returns of the Fund's specific equity investment
category may lag the returns of the overall stock market. For example, the
Fund's "large cap" approach carries the risk that in certain markets large cap
stocks will underperform mid cap and small cap stocks.

Secondary

Derivatives Risk: Certain derivative instruments (such as options, futures and
swaps) can produce disproportionate gains or losses. They are generally con-
sidered more risky than direct equity investments. Also, in a down market,
derivatives could become harder to value or sell at a fair price.

Large Cap Value Fund

GOAL AND STRATEGY

This is a large cap stock fund with a value emphasis that seeks long-term
growth in capital and substantial dividend income.

The Fund invests primarily in a diversified mix of common stocks of large
established U.S. companies that are believed to offer favorable prospects for
increasing dividends and growth in capital.

The manager employs a value approach in selecting stocks using proprietary
equity research. Stocks are purchased that are undervalued by various measures
such as the stock's current price relative to its earnings potential.

The manager looks for companies with:

 . established operating history;

 . above-average dividend yield relative to the S&P 500 Index;

 . low price/earnings ratio relative to the S&P 500 Index;

 . sound balance sheet and other positive financial characteristics; and

 . low stock price relative to the company's underlying value.

The Fund normally invests in 100 to 175 stocks, with at least 65% (usually
higher) of its assets in large cap companies. The Fund normally has 5% or less
of its assets in cash and cash equivalents.

The Fund may purchase other types of securities, for example: American Deposi-
tory Receipts (ADRs), foreign equity securities of developed countries, high
quality intermediate and short-term debt securities, and certain derivatives
(investments whose value is based on indices or other securities).

In abnormal market conditions, the Fund may take temporary defensive measures--
such as holding unusually large amounts of cash and cash equivalents--that are
inconsistent with the Fund's primary investment strategy. In taking those mea-
sures, the Fund may not achieve its investment goal.

PAST PERFORMANCE

The graph shows how the fund's total return has varied from year to year, while
the table shows performance over time (along with a broad-based market index
for reference). This information may also help provide an indication of the
fund's risks and potential rewards. All figures assume dividend reinvestment.
Past performance does not indicate future results. The performance figures
below do not reflect the deduction of fees and charges payable under the
variable contracts. Such fees and charges would cause the investment returns
under the contracts to be less than that shown below.

will underperform "growth" stocks. Also, the Fund's "large cap" approach car-
ries the risk that in certain markets large cap stocks will underperform small
cap and mid cap stocks.

Secondary

Foreign Risk: The Fund's foreign securities will pose special risks, due to
limited government regulation, lack of public information, economic, political
and social instability and foreign currency rate fluctuations. Factors such as
lack of liquidity, foreign ownership limits and restrictions on removing cur-
rency also pose special risks.

Derivatives Risk: Certain derivative instruments (such as options, futures and
swaps) can produce disproportionate gains or losses. They are generally consid-
ered more risky than direct equity investments. Also, in a down market, deriva-
tives could become harder to value or sell at a fair price.

Large Cap Growth Fund

GOAL AND STRATEGY

This is a large cap stock fund with a growth emphasis that seeks growth in
capital.

The Fund invests primarily in a diversified mix of common stocks of large
established U.S. companies that are believed to offer above-average potential
for growth in revenues and earnings.

The manager selects stocks using a combination of proprietary equity research
and quantitative tools. Stocks are purchased that are undervalued relative to
the stock's history and have improving earnings growth prospects. The Fund is
managed using risk control techniques that maintain risk and industry charac-
teristics similar to the Russell 1000(R) Growth Index.

The Fund normally invests in 80 to 150 stocks, with at least 65% (usually high-
er) of its assets in large cap companies. The Fund normally has 5% or less of
its assets in cash and cash equivalents.

The Fund may purchase other types of securities, for example: American Deposi-
tory Receipts (ADRs), and certain derivatives (investments whose value is based
on indices or other securities).

In abnormal market conditions, the Fund may take temporary defensive measures--
such as holding unusually large amounts of cash and cash equivalents--that are
inconsistent with the Fund's primary investment strategy. In taking those mea-
sures, the Fund may not achieve its investment goal.

Large Cap Aggressive Growth Fund

GOAL AND STRATEGY

This is a non-diversified large cap stock fund with a growth emphasis that
seeks long-term growth in capital.

The Fund invests primarily in the common stocks of large established U.S. com-
panies that are believed to offer above-average potential for long-term growth
in revenues and earnings.

The manager selects stocks using proprietary company-specific research that
focuses on firms:

 . offering superior earnings growth that is not fully reflected in current mar-
  ket valuations,

 . having prospective earnings growth rates substantially above that of the S&P
  500, and

 . exhibiting strong management, superior industry positions and excellent bal-
  ance sheets.

The Fund employs aggressive investment strategies and invests most of its asset
in a relatively small number of companies, with the 25 most highly regarded
stocks representing at least 65% of the Fund's assets. The manager selects
stocks without regard to any predefined industry or sector selection criteria.

The manager actively trades and adjusts the Fund's holdings to capitalize on
market fluctuations. The manager typically:

 . increases investment in favored securities and reduces the number of holdings
  in declining markets, and

 . decreases investment in favored securities and increases the number of hold-
  ings in rising markets.

The Fund is a non-diversified fund, which means it can take larger positions in
a smaller number of issuers. The Fund normally invests in 35 to 55 stocks, with
at least 65% (usually higher) of its assets in large cap companies. The Fund
normally has 5% or less of its assets in cash and cash equivalents.

The Fund may purchase other types of securities, for example: American Deposi-
tory Receipts (ADRs), and certain derivatives (investments whose value is based
on indices or other securities).

In abnormal market conditions, the Fund may take temporary defensive measures--
such as holding unusually large amounts of cash and cash equivalents--that are
inconsistent with the Fund's primary investment strategy. In taking those mea-
sures, the Fund may not achieve its investment goal.

PAST PERFORMANCE

Because this Fund did not have a full year of operations as of December 31,
1999, no year-by-year total returns or average annual total returns can be
shown for this Fund. However, the Appendix to this prospectus contains certain
performance information that is relevant to this Fund. The Appendix starts on
page 59.

MAIN RISKS

Primary

Market Risk: The value of the securities in the Fund may go down in response to
overall stock or bond market movements. Markets tend to move in cycles, with
periods of rising prices and periods of falling prices. Stocks tend to go up
and down in value more than bonds. If the Fund's investments are concentrated
in certain sectors, the Fund's performance could be worse than the overall mar-
ket.

Non-Diversified Fund Risk: The Fund's larger position in individual issuers and
in a smaller number of issuers could produce more volatile performance relative
to more diversified funds. The less diversified a fund's holdings are, the more
likely it is that a specific security's poor performance will hurt the fund
significantly.

Manager Risk: The manager and its strategy may fail to produce the intended
results. The Fund could underperform its peers or lose money if the manager's
investment strategy does not perform as expected.

Investment Category Risk: The returns of the Fund's specific equity investment
category may lag the returns of the overall stock market. For example, the
Fund's "growth" approach carries the risk that in certain markets "growth"
stocks will underperform "value" stocks. Also, the Fund's "large cap" approach
carries the risk that large cap stocks will underperform small cap and mid cap
stocks.

Concentration Risk: The Fund's investment in securities of a smaller number of
issuers could produce more volatile performance relative to funds that invest
in a larger number of issuers. The more concentrated a fund's holdings are, the
more likely it is a specific security's poor performance will hurt the fund
significantly.

Turnover Risk: In general, the greater the volume of buying and selling by a
fund (i.e., the higher its "turnover rate"), the greater the impact that bro-
kerage commissions and other transaction costs will have on the fund's perfor-
mance. Any turnover rate in excess of 100% is considered relatively high. Nor-
mally, the Fund's turnover rate will be greater than 100%.

Secondary

Derivatives Risk: Certain derivative instruments (such as options, futures and
swaps) can produce disproportionate gains or losses. They are generally consid-
ered more risky than direct equity investments. Also, in a down market, deriva-
tives could become harder to value or sell at a fair price.

Mid Cap Value Fund

GOAL AND STRATEGY

This is a mid cap stock fund with a value emphasis that seeks long-term growth
in capital.

The Fund invests primarily in the common stocks of mid-sized U.S. companies
that are believed to sell at a discount to their intrinsic value.

The manager selects stocks using proprietary equity research. Stocks are pur-
chased that are undervalued by various measures such as the stock's current
price relative to its earnings potential.

The manager looks for undervalued companies with:

 . sound balance sheet and other financial characteristics;

 . consistent cash flow;

 . strong position relative to the competition; and

 . high level of stock ownership among management.

The Fund normally invests in 50 to 75 stocks, with at least 65% (usually high-
er) of its assets in mid cap companies. The Fund normally has 5% or less of its
assets in cash and cash equivalents.

The Fund may purchase other types of securities, for example: American Deposi-
tory Receipts (ADRs), and certain derivatives (investments whose value is based
on indices or other securities).

In abnormal market conditions, the Fund may take temporary defensive measures--
such as holding unusually large amounts of cash and cash equivalents--that are
inconsistent with the Fund's primary investment strategy. In taking those mea-
sures, the Fund may not achieve its investment goal.

risks and potential rewards. All figures assume dividend reinvestment. Past
performance does not indicate future results. The performance figures below do
not reflect the deduction of fees and charges payable under the variable
contracts. Such fees and charges would cause the investment returns under the

The Fund is non-diversified, which means it can take larger positions in a

lack of liquidity, foreign ownership limits and restrictions on removing cur-
rency also pose special risks.

Derivatives Risk: Certain derivative instruments (such as options, futures and
swaps) can produce disproportionate gains or losses. They are generally consid-
ered more risky than direct equity investments. Also, in a down market, deriva-
tives could be- come harder to value or sell at a fair price.

Fundamental Mid Cap Growth Fund


GOAL AND STRATEGY

This is a mid cap stock fund with a growth emphasis that seeks long-term growth
in capital.

The Fund invests primarily in the common stocks of mid-sized U.S. companies
that are believed to offer above-average potential for growth in revenues and
earnings.

The manager selects stocks using both proprietary equity research and external
consensus earnings forecasts. Stocks are purchased that are believed to offer:

 . High rate of sustainable earnings growth of 15% plus,

 . revenue growth generated by operating results (unit volume); and

 .sustainable revenue growth of 10% plus.

The manager looks for companies with:

 . innovative management and strong leadership positions in unique market
  niches;

 . undiscovered and undervalued emerging growth opportunities; and,

 . new products and services.

The Fund's industry exposures are a result of stock selection as opposed to
predetermined allocations.

The Fund normally invests in 60 to 80 stocks, with at least 65% (usually high-
er) of its assets in mid cap companies. The Fund normally has 5% or less of its
assets in cash and cash equivalents.

The Fund may purchase other types of securities, for example: American Deposi-
tory Receipts (ADRs), and certain derivatives (investments whose value is based
on indices or other securities).

In abnormal market conditions, the Fund may take temporary defensive measures--
such as holding unusually large amounts of cash and cash equivalents--that are
inconsistent with the Fund's primary investment strategy. In taking those mea-
sures, the Fund may not achieve its investment goal.

MAIN RISKS

Primary

Small /Mid Cap Stock Risk: The Fund's investment in smaller or mid-sized compa-
nies may be subject to more erratic price movements than investment in large
established companies.

Market Risk: The value of the securities in the Fund may go down in response to
overall stock or bond market movements. Markets tend to move in cycles, with
periods of rising prices and periods of falling prices. Stocks tend to go up
and down in value more than bonds. If the Fund's investments are concentrated
in certain sectors, the Fund's performance could be worse than the overall mar-
ket.

Manager Risk: The manager and its strategy may fail to produce the intended
results. The Fund could underperform its peers or lose money if the manager's
investment strategy does not perform as expected.

Investment Category Risk: The returns of the Fund's specific equity investment
category may lag the returns of the overall stock market. For example, the
Fund's "growth" approach carries the risk that in certain markets "growth"
stocks will underperform "value" stocks. Also, the Fund's "mid cap" approach
carries the risk that mid cap stocks will underperform large cap and small cap
stocks.

Concentration Risk: The Fund's investment in securities of a smaller number of
issuers could produce more volatile performance relative to funds that invest
in a larger number of issuers. The more concentrated a fund's holdings are, the
more likely it is a specific security's poor performance will hurt the fund
significantly.

Turnover Risk: In general, the greater the volume of buying and selling by a
fund (i.e., the higher its "turnover rate"), the greater the impact that bro-
kerage commissions and other transaction costs will have on the fund's perfor-
mance. Any turnover rate in excess of 100% is considered relatively high. Nor-
mally, the Fund's turnover rate will be greater than 100%.

Secondary

Derivatives Risk: Certain derivative instruments (such as options, futures and
swaps) can produce disproportionate gains or losses. They are generally consid-
ered more risky than direct equity investments. Also, in a down market, deriva-
tives could become harder to value or sell at a fair price.

Real Estate Equity Fund

GOAL AND STRATEGY

This is a real estate stock fund that seeks above-average income and long-term
growth in capital.

The Fund invests primarily in:

 . equity securities of real estate investment trusts (REITs) that own commer-
  cial and multi-family residential real estate; and

 . equity securities of real estate operating companies (i.e., companies with at
  least 75% of revenue, income or fair asset value derived from real estate).

The manager selects real estate stocks using a combination of proprietary,
equity research and quantitative tools. Real estate stocks are purchased that
are undervalued relative to the stock's history and the market and have improv-
ing earnings growth prospects.

The manager looks for real estate stocks with:

 . proven track records,

 . strong management whose interests are aligned with shareholders,

 . attractive real estate holdings, and

 . a flexible financial structure.

The manager employs risk control techniques to maintain risk, style and indus-
try characteristics similar to the public equity real estate market. The Fund
normally invests in 30 to 60 securities. The Fund normally has 5% or less of
its assets in cash and cash equivalents.

The Fund also may purchase other types of securities, for example: American
Depository Receipts (ADRs), convertible securities, and equity securities of
non-real estate businesses whose real estate holdings are significant in rela-
tion to their market capitalization.

In abnormal market conditions, the Fund may take temporary defensive measures--
such as holding unusually large amounts of cash and cash equivalents--that are
inconsistent with the Fund's primary investment strategy. In taking those mea-
sures, the Fund may not achieve its investment goal.

PAST PERFORMANCE

The graph shows how the fund's total return has varied from year to year, while
the table shows performance over time (along with a broad-based market index
for reference). This information may help provide an indication of the fund's
risks and potential rewards. All figures assume dividend reinvestment. Past
performance does not indicate future results. The performance figures below do
not reflect the deduction of fees and charges payable under the variable
contracts. Such fees and charges would cause the investment returns under the
contracts to be less than that shown below.

MAIN RISKS

Primary

Real Estate Securities Risk: Real estate investment trusts (REITs) or other
real estate-related equity securities may be affected by changes in the value
of the underlying property owned by the trust. Mortgage REITs may be affected
by the quality of any credit extended. Other potential risks include the possi-
bility of failing to qualify for tax-free pass-through of income under the
Internal Revenue Code or failing to maintain exemption under the Investment
Company Act of 1940.

Market Risk: The value of the securities in the Fund may go down in response to
overall stock or bond market movements. Markets tend to move in cycles, with
periods of rising prices and periods of falling prices. Stocks tend to go up
and down in value more than bonds. If the Fund's investments are concentrated
in certain sectors, the Fund's performance could be worse than the overall mar-
ket.

Manager Risk: The manager and its strategy may fail to produce the intended
results. The Fund could underperform its peers or lose money if the manager's
investment strategy does not perform as expected.

issuers could produce more volatile performance relative to funds that invest
in a larger number of issuers. The more concentrated a fund's holdings are, the
more likely it is a specific security's poor performance will hurt the fund
significantly.

Small /Mid Cap Stock Risk: The Fund's investment in smaller or mid-sized compa-
nies may be subject to more erratic price movements than investment in large
established companies.

Small/Mid Cap CORE Fund
GOAL AND STRATEGY

This is a small/mid cap stock fund that seeks long-term growth in capital.

The Fund invests primarily in a diversified mix of the common stocks of small
and mid-sized U.S. companies that are believed to offer:

 . favorable prospects for increasing dividends and capital appreciation (i.e.,
  "value" companies); and

 . above-average potential for growth in revenues and earnings (i.e. "growth"
  companies).

The manager selects stocks using a combination of quantitative techniques and
equity research. The manager employs an investment process known as CORE, "Com-
puter Optimized, Research-Enhanced," that employs a proprietary quantitative
model. Stocks are purchased that have strong expected earnings growth and
momentum and better valuation and risk characteristics than the Russell
2500(TM) Index. The Fund is managed using risk control techniques to maintain
risk, style, capitalization and industry characteristics similar to the Russell
2500(TM) Index.

The Fund normally invests in 200 to 600 stocks, with at least 65% (usually
higher) of the Fund's assets in small cap and mid cap companies. The Fund nor-
mally has 10% or less of its assets in cash and cash equivalents.

The Fund may purchase other types of securities, for example: American Deposi-
tory Receipts (ADRs), Standard & Poor's Depository Receipts (SPDRs), and cer-
tain derivatives (investments whose value is based on indices or other securi-
ties).

In abnormal market conditions, the Fund may take temporary defensive measures--
such as holding unusually large amounts of cash and cash equivalents--that are
inconsistent with the Fund's primary investment strategy. In taking those mea-
sures, the Fund may not achieve its investment goal.

MAIN RISKS

Primary

Small /Mid Cap Stock Risk: The Fund's investment in smaller or mid-sized compa-
nies may be subject to more erratic price movements than investment in large
established companies.

Market Risk: The value of the securities in the Fund may go down in response to
overall stock or bond market movements. Markets tend to move in cycles, with
periods of rising prices and periods of falling prices. Stocks tend to go up
and down in value more than bonds. If the Fund's investments are concentrated

ket.

Manager Risk: The manager and its strategy may fail to produce the intended
results. The Fund could underperform its peers or lose money if the manager's
investment strategy does not perform as expected.

Investment Category Risk: The returns of the Fund's specific equity investment
category may lag the returns of the overall stock market. For example, the
Fund's "small/mid cap" approach carries the risk that in certain markets
small/mid cap stocks will underperform large cap stocks.

Turnover Risk: In general, the greater the volume of buying and selling by a
fund (i.e., the higher its "turnover rate"), the greater the impact that bro-
kerage commissions and other transaction costs will have on the fund's perfor-
mance. Any turnover rate in excess of 100% is considered relatively high. The
Fund had unusually high turnover in 1999 and is expected to experience similar
turnover in 2000. This higher than expected turnover is due to (i) the rela-
tively small size of the Fund, which magnifies the effect of contributions and
redemptions, and (ii) the high volatility of the market, which in 1999 resulted
in the subadviser implementing procedures to reduce the Fund's tracking risk.
Normally, the Fund's turnover rate will be less than 100%.

Secondary

Derivatives Risk: Certain derivative instruments (such as options, futures and
swaps) can produce disproportionate gains or losses. They are generally consid-
ered more risky than direct equity investments. Also, in a down market, deriva-
tives could become harder to value or sell at a fair price.

Small/Mid Cap Growth Fund

GOAL AND STRATEGY

This is a small/mid cap stock fund with a growth emphasis that seeks long-term
growth in capital.

The Fund invests primarily in the common stocks of small and mid-sized U.S.
companies that are believed to offer above-average potential for growth in rev-
enues and earnings.

The manager selects stocks using a combination of proprietary quantitative and
qualitative equity research. Quantitative screening seeks to identify a group
of high-quality companies with above-average growth characteristics relative to
industry peers. Equity research seeks to identify individual companies from
that group with a higher potential for long term earnings growth and capital
appreciation.

The manager buys companies that seem attractive based on a combination of cri-
teria, among others:

 . Superior historical earnings growth,

 . Prospects for above-average growth,

 . Attractive valuations,

 . Strong market positions,

 . Favorable new products, and

 . Superior management.

The Fund is broadly diversified by industry sector. The Fund normally invests
in 60 to 100 stocks, with at least 65% (usually higher) of its assets in small
and mid cap companies. The Fund normally has 5% or less of its assets in cash
and cash equivalents.

The Fund may purchase other types of securities, for example: American Deposi-
tory Receipts (ADRs), and certain derivatives (investments whose value is based
on indices or other securities).

In abnormal market conditions, the Fund may take temporary defensive measures--
such as holding unusually large amounts of cash and cash equivalents--that are
inconsistent with the Fund's primary investment strategy. In taking those mea-
sures, the Fund may not achieve its investment goal.

PAST PERFORMANCE

The graph shows how the fund's total return has varied from year to year, while
the table shows performance over time (along with a broad-based market index
for reference). This information may help provide an indication of the fund's
risks and potential rewards. All figures assume dividend reinvestment. Past
performance does not indicate future results. The performance figures below do
not reflect the deduction of fees and charges payable under the variable
contracts. Such fees and charges would cause the investment returns under the
contracts to be less than that shown below.

MAIN RISKS

Primary

Small /Mid Cap Stock Risk: The Fund's investment in smaller or mid-sized compa-
nies may be subject to more erratic price movements than investment in large
established companies.

Market Risk: The value of the securities in the Fund may go down in response to
overall stock or bond market movements. Markets tend to move in cycles, with
periods of rising prices and periods of falling prices. Stocks tend to go up
and down in value more than bonds. If the Fund's investments are concentrated
in certain sectors, the Fund's performance could be worse than the overall mar-
ket.

Manager Risk: The manager and its strategy may fail to produce the intended
results. The Fund could underperform its 29 peers or lose money if the manager's
investment strategy does not perform as expected.

Investment Category Risk: The returns of the Fund's specific equity investment
category may lag the returns of the overall stock market. For example, the
Fund's "growth" approach carries the risk that in certain markets "growth"
stocks will underperform "value" stocks. Also, the Fund's "small/mid cap"
approach carries the risk that in certain markets small/mid cap stocks will
underperform large cap stocks.

Concentration Risk: The Fund's investment in securities of a smaller number of
issuers could produce more volatile performance relative to funds that invest
in a larger number of issuers. The more concentrated a fund's holdings are, the
more likely it is a specific security's poor performance will hurt the fund
significantly.

Turnover Risk: In general, the greater the volume of buying and selling by a
fund (i.e., the higher its "turnover rate"), the greater the impact that bro-
kerage commissions and other transaction costs will have on the fund's perfor-
mance. Any turnover rate in excess of 100% is considered relatively high. The
Fund had a high turnover rate in 1999 because of a change in management and a
change in the Fund's investment strategy. These changes required a restructur-
ing of the Fund's investments. In future years, the Fund's turnover rate will
normally be less than 100%.

Small Cap Value Fund

GOAL AND STRATEGY

This is a small cap stock fund with a value emphasis that seeks long-term
growth in capital.

The Fund invests primarily in a diversified mix of the common stocks of small
U.S. companies that are believed to offer favorable prospects for increasing
dividends and capital appreciation.

The manager applies a combination of quantitative techniques and equity
research to identify the best values among small company stocks.

Stocks are evaluated based on multiple factors, including:

 . earnings-to-price ratios;

 . earnings estimate revisions;

 . relative price strength; and

 . share issuance/buyback.

The Fund is managed using risk control techniques to maintain risk, style, cap-
italization and industry characteristics similar to the Russell 2000(R) Value
Index. The Fund normally invests in 150 to 250 stocks, with at least 65% (usu-
ally higher) of its assets in small cap companies. The Fund normally has 5% or
less of its assets in cash and cash equivalents.

The Fund may purchase other types of securities, for example: American Deposi-
tory Receipts (ADRs), and certain derivatives (investments whose value is based
on indices or other securities).

In abnormal market conditions, the Fund may take temporary defensive measures--
such as holding unusually large amounts of cash and cash equivalents--that are
inconsistent with the Fund's primary investment strategy. In taking those mea-
sures, the Fund may not achieve its investment goal.

Small Cap Growth Fund

GOAL AND STRATEGY

This is a small cap stock fund with a growth emphasis that seeks long-term
growth in capital.

The Fund invests primarily in a diversified mix of the common stocks of small
U.S. companies that are believed to offerabove-average potential for growth in
revenues and earnings.

The manager selects stocks using proprietary equity research. Stocks are pur-
chased that are expected to have rapid earnings growth that is not yet widely
recognized by the investment community.

The manager looks for companies with:

 . demonstrated annual 20% earnings growth over 3 years and/or similar future
  growth expectations;

 . dominant market niche or poised to become market leaders; and

 . high quality senior management with coherent business strategies.

The Fund is highly diversified by sector and number of individual stocks. The
Fund's sector weightings are broadly diversified and managed relative to those
of the Russell 2000(R) Growth Index. The Fund normally invests in 150 to 220
stocks, with at least 65% (usually higher) of its assets in small cap compa-
nies. The Fund normally has 5% or less of its assets in cash and cash equiva-
lents.

The Fund may purchase other types of securities, for example: American Deposi-
tory Receipts (ADRs), and certain derivatives (investments whose value is based
on indices or other securities).

In abnormal market conditions, the Fund may take temporary defensive measures--
such as holding unusually large amounts of cash and cash equivalents--that are
inconsistent with the Fund's primary investment strategy. In taking those mea-
sures, the Fund may not achieve its investment goal.

Global Equity Fund
GOAL AND STRATEGY

This is a global stock fund that seeks long-term growth in capital.

The Fund primarily invests in a diversified mix of common stocks of:

 . large established U.S. companies; and

 . large established foreign companies located in countries throughout the
  world, including developed, newly industrialized, and emerging countries.

The manager makes ongoing decisions about the mix between U.S. and foreign
stocks. The manager has a target mix of 40% in U.S. stocks and 60% in foreign
stocks, but actively manages the mix within (+/-) 20 percentage points of the
target mix.

The manager uses global economic and industry analysis to identify global eco-
nomic and industry themes. The manager looks for companies that will benefit
from:

 . global economic trends;

 . promising technologies or products; and

 . specific country opportunities resulting from changing geopolitical, currency
  or economic relationships.

The manager purchases stocks of companies that are:

 . in growth industries;

 . efficient producers; and

 . undervalued relative to long-term growth potential.

The Fund invests:

 . in at least 3 different countries (including the U.S.), but normally in more
  than 15 countries; and

 . no more than 10% of its assets in emerging markets stocks.

Although the Fund may employ foreign currency hedging techniques, the Fund nor-
mally maintains the currency exposure of the underlying equity investments.

The Fund normally invests in 90 to 120 stocks, with at least 65% (usually high-
er) of its assets in large cap companies. The Fund normally has 5% or less of
its assets in cash and cash equivalents.

The Fund may purchase other types of securities, for example: American Deposi-
tory Receipts (ADRs), Global Depository Receipts (GDRs), European Depository
Receipts (EDRs), and certain derivatives (investments whose value is based on
indices or other securities).

In abnormal market conditions, the Fund may take temporary defensive measures--
such as holding unusually large amounts of cash and cash equivalents or invest-
ing 100% of its assets in U.S. companies--that are inconsistent with the Fund's
primary investment strategy. In taking those measures, the Fund may not achieve
its investment goal.

MAIN RISKS

Primary

Foreign Risk: The Fund's foreign securities will pose special risks, due to
limited government regulation, lack of public information, economic, political
and social instability and foreign currency rate fluctuations. Factors such as
lack of liquidity, foreign ownership limits and restrictions on removing cur-
rency also pose special risks. All foreign securities have some degree of for-
eign risk. However, to the extent the Fund invests in emerging market coun-
tries, it will have a significantly higher degree of foreign risk than if it
invested exclusively in developed or newly-industrialized countries.
Market Risk: The value of the securities in the Fund may go down in response
to overall stock or bond market movements. Markets tend to move in cycles,
with periods of rising prices and periods of falling prices. Stocks tend to go
up and down in value more than bonds. If the Fund's investments are concen-
trated in certain sectors, the Fund's performance could be worse than the
overall market.

Market Allocation Risk: The allocation of the Fund's assets among domestic and
international equity regions may (1) reduce the Fund's holdings in a region
whose value then increases unexpectedly, or (2) increase the Fund's holdings
in a region just prior to its experiencing a loss of value.
Manager Risk: The manager and its strategy may fail to produce the intended
results. The Fund could underperform its peers or lose money if the manager's
investment strategy does not perform as expected.


Secondary

Derivatives Risk: Certain derivative instruments (such as options, futures and
swaps) can produce disproportionate gains or losses. They are generally con-
sidered more risky than direct equity investments. Also, in a down market,
derivatives could become harder to value or sell at a fair price.

Global Balanced Fund
(Formerly International Balanced Fund)

GOAL AND STRATEGY

This is a non-diversified global balanced stock and bond fund that seeks long-
term growth in income and capital.

The Fund invests primarily in a mix of:

 . U.S. and foreign common stocks of large companies within developed markets;
  and

 . U.S. and foreign investment grade bonds of issuers within developed markets
  with maturities generally greater than 12 months.

The manager makes ongoing decisions about the mix between stocks and bonds. The
manager has a target mix of 65% stocks and 35% bonds, but actively manages the
mix within (+/-) 10 percentage points of the target mix.

The Fund invests:

 . in at least 3 different countries, but normally invests in 10 to 20 coun-
  tries; and

 . no more than 10% of its assets in emerging market stocks and bonds.

The manager selects stocks and bonds using fundamental value analysis to iden-
tify fairly priced investments with long-term sustainable cash flows. The man-
ager determines fundamental value by focusing on:

 . current market prices relative to fundamental values;

 . broad-based indices for stocks, bonds, and markets; and

 . economic variables such as productivity, inflation and global competitive-
  ness.

The Fund is non-diversified, which means that it can take larger positions in a
smaller number of issuers. However, the Fund normally invests in 125 to 250
stocks within the stock portion. The Fund normally has 10% or less of its
assets in cash and cash equivalents.

The Fund may purchase other types of securities, for example: American Deposi-
tory Receipts (ADRs), Global Depository Receipts (GDRs), European Depository
Receipts (EDRs), high yield bonds, and certain derivatives (investments whose
value is based on indices or other securities).

The manager actively uses derivatives, such as futures and forwards, to manage
the Fund's average maturity relative to the Salomon Brothers World Government
Bond Index Unhedged and to implement foreign currency strategies. Currency man-
agement strategies are primarily used for hedging purposes and to protect
against anticipated changes in foreign currency exchange rates.

In abnormal market conditions, the Fund may take temporary defensive measures--
such as holding unusually large amounts of cash and cash equivalents--that are
inconsistent with the Fund's primary investment strategy. In taking those mea-
sures, the Fund may not achieve its investment goal.

MAIN RISKS

Primary

Foreign Risk: The Fund's foreign securities will pose special risks, due to
limited government regulation, lack of public information, economic, political
and social instability and foreign currency rate fluctuations. Factors such as
lack of liquidity, foreign ownership limits and restrictions on removing cur-
rency also pose special risks. All foreign securities have some degree of for-
eign risk. However, to the extent the Fund invests in emerging market coun-
tries, it will have a significantly higher degree of foreign risk than if it
invested exclusively in developed or newly-industrialized countries.

Non-Diversified Fund Risk: The Fund's larger position in foreign government
securities could produce more volatile performance relative to funds with
smaller positions. The less diversified a fund's holdings are, the more likely
it is that a specific security's poor performance will hurt the fund signifi-
cantly.

Market Risk: The value of the securities in the Fund may go down in response to
overall stock or bond market movements. Markets tend to move in cycles, with
periods of rising prices and periods of falling prices. Stocks tend to go up
and down in value more than bonds. If the Fund's investments are concentrated
in certain sectors, the Fund's performance could be worse than the overall mar-
ket.
Manager Risk: The manager and its strategy may fail to produce the intended
results. The Fund could underperform its peers or lose money if the manager's
investment strategy does not perform as expected.

Investment Category Risk: The returns of the Fund's specific equity investment
category may lag the returns of the overall stock market. For example, the
Fund's "value" approach carries the risk that in certain markets "value" stocks
will underperform "growth" stocks. Also, the Fund's "large/mid cap" approach
carries the risk that large/mid cap stocks will underperform small cap stocks.

Market Allocation Risk: The allocation of the Fund's assets between the major
asset classes (i.e., stocks and bonds) may (1) reduce the Fund's holdings in a
class whose value then increases unexpectedly, or (2) increase the Fund's hold-
ings in a class just prior to its experiencing a loss of value.

Interest Rate Risk: When interest rates rise, the Fund's bond yields will gen-
erally rise and the Fund's bond prices will generally fall. When interest rates
fall, the reverse will generally occur. The longer the average remaining matu-
rity of bonds held by the Fund, the more sensitive the Fund is to interest rate
risk. This Fund has more interest rate risk than a short-term bond fund, but
less interest rate risk than a long-term bond fund.
Credit Risk: An issuer of a bond held by the Fund may default on its obligation
to pay interest and repay principal. Also, the credit rating of a bond held by
the fund may be downgraded. In either case, the value of the bond held by the
Trust would fall. All bonds have some credit risk, but in general lower-rated
bonds have higher credit risk.

Turnover Risk. In general, the greater the volume of buying and selling by a
fund (i.e., the higher its "turnover rate"), the greater the impact that bro-
kerage commissions and other transaction costs will have on the fund's perfor-
mance. Any turnover rate in excess of 100% is considered relatively high. Nor-
mally, the Fund's turnover rate will be greater than 100%.

Secondary

Derivatives Risk: Certain derivative instruments (such as options, futures and
swaps) can produce disproportionate gains or losses. They are generally consid-
ered more risky than direct equity investments. Also, in a down market, deriva-
tives could become harder to value or sell at a fair price.

High Yield Bond Risk. Junk bonds, defined as bond securities rated below BBB-
/Baa3, may be subject to more volatile or erratic price movements due to
investor sentiment. In a down market, these high yield securities become harder
to value or to sell at a fair price.

International Equity Index Fund

GOAL AND STRATEGY

This is an international stock fund that seeks to track the performance of
broad-based equity indices of foreign companies in developed and emerging mar-
kets.

The Fund is managed relative to a target mix of 90% in the MSCI EAFE GDP Index
and 10% in the MSCI EMF Index. The EAFE GDP Index, known as the Europe Austral-
asia and Far East Index, includes foreign companies in developed markets, with
country index weights based upon a country's Gross Domestic Product (GDP). The
EMF Index, known as the Emerging Markets Free Index, includes foreign companies
in emerging markets, with country index weights based upon a country's market
capitalization.

The manager employs a passive management strategy using quantitative techniques
to invest in a representative sample of stocks in the Index. The manager
selects stocks in an attempt to track, as closely as possible, the characteris-
tics of the Index, including country and sector weights. The Fund normally
invests in 400 to 1,200 stocks.

The Index composition changes from time to time. The manager will reflect those
changes as soon as practical.

The Fund is normally fully invested. The manager may invest in stock index
futures to maintain market exposure and manage cash flow. Although the Fund may
employ foreign currency hedging techniques, the Fund normally maintains the
currency exposure of the underlying equity investments.


The Fund may purchase other types of securities, for example: American Deposi-
tory Receipts (ADRs), Global Depository Receipts (GDRs), European Depository
Receipts (EDRs), cash equivalents, and certain derivatives (investments whose
value is based on indices or other securities).

PAST PERFORMANCE

The graph shows how the fund's total return has varied from year to year, while
the table shows performance over time (along with a broad-based market index
for reference). This information may help provide an indication of the fund's
risks and potential rewards. All figures assume dividend reinvestment. Past
performance does not indicate future results. The performance figures below do
not reflect the deduction of fees and charges payable under the variable
contracts. Such fees and charges would cause the investment returns under the
contracts to be less than that shown below.

MAIN RISKS
Primary
Foreign Risk: The Fund's foreign securities will pose special risks, due to
limited government regulation, lack of public information, economic, political
and social instability and foreign currency rate fluctuations. Factors such as
lack of liquidity, foreign ownership limits and restrictions on removing cur-
rency also pose special risks. All foreign securities have some degree of for-
eign risk. However, to the extent the Fund invests in emerging market coun-
tries, it will have a significantly higher degree of foreign risk than if it
invested exclusively in developed or newly-industrialized countries.


Index Management Risk: Certain factors such as the following may cause the
Fund to track the Index less closely:


 . The securities selected by the manager may not be fully representative of
  the Index.

 . Transaction expenses of the Fund may result in the Fund's performance being
  different than that of the Index.
 . The size and timing of the Fund's cash flows may result in the Fund's per-
  formance being different than that of the Index.


Also, index funds like this one will have more difficulty in taking defensive
positions in abnormal market conditions.


Market Risk: The value of the securities in the Fund may go down in response
to overall stock or bond market movements. Markets tend to move in cycles,
with periods of rising prices and periods of falling prices.

Stocks tend to go up and down in value more than bonds. If the Fund's invest-
ments are concentrated in certain sectors, the Fund's performance could be
worse than the overall market.


Manager Risk: The manager and its strategy may fail to produce the intended
results. The Fund could underperform its peers or lose money if the manager's
investment strategy does not perform as expected.


Secondary
Derivatives Risk:  Certain derivative instruments (such as options, futures
and swaps) can produce disproportionate gains or losses. They are generally
considered more risky than direct equity investments. Also, in a down market,
derivatives could become harder to value or sell at a fair price.

International Opportunities Fund

GOAL AND STRATEGY

This is an international stock fund that seeks long-term growth in capital.

The Fund primarily invests in a diversified mix of common stocks of large
established and medium-sized foreign companies located throughout the world,
including developed, newly industrialized, and emerging countries.

The manager determines the distribution among countries and regions by using a
combination of fundamental research and economic analysis, emphasizing:

 . prospects for relative economic growth between foreign countries;

 . expected levels of inflation;

 . government policies influencing business conditions; and

 . outlook for currency relationships.
The manager selects stocks that have growth characteristics such as:

 . leading market position or technological leadership;

 . high return on invested capital;

 . healthy balance sheets with relatively low debt;

 . strong competitive advantage;

 . strength of management; and

 . earnings growth and cash flow sufficient to support growing dividends.

The Fund invests:

 . in at least 3 different countries; and

 . no more than 20% of its assets in emerging market stocks.

Although the Fund may employ foreign currency hedging techniques, the Fund nor-
mally maintains the currency exposure of the underlying equity investments.
The Fund normally invests in 200 to 300 stocks in 15 to 20 countries. The Fund
normally has 10% or less of its assets in cash and cash equivalents.

The Fund also may purchase other types of securities, for example: American
Depository Receipts (ADRs), Global Depository Receipts (GDRs), European Deposi-
tory Receipts (EDRs), and certain derivatives (investments whose value is based
on indices or other securities).

In abnormal market conditions, the Fund may take temporary defensive measures--
such as holding unusually large amounts of cash and cash equivalents--that are
inconsistent with the Fund's primary investment strategy. In taking those mea-
sures, the Fund may not achieve its investment goal.

Emerging Markets Equity Fund

GOAL AND STRATEGY

This is an emerging markets stock fund that seeks long-term growth in capital.

The Fund invests primarily in the stocks of companies in countries having econ-
omies or markets generally considered by the World Bank or United Nations to be
emerging or developing.

In making country allocation decisions, the manager analyzes the global envi-
ronment and selects countries with:

 . Improving macroeconomic, political and social trends, and

 . attractive valuation levels.

The manager selects stocks using fundamental proprietary research to identify
companies:

 . having strong earnings growth potential,

 . selling below their intrinsic value, and

 . having shareholder-focused management, dominant products, and well estab-
  lished distribution channels.

The Fund normally invests:

 . in at least 15 emerging market countries, and

 . no more than 30% of its assets in any single country.

The Fund normally invests in 100 to 250 stocks in 20 to 25 countries. The Fund
normally has 10% or less of its assets in cash and cash equivalents.

Although the Fund may employ foreign currency hedging techniques, the Fund
normally maintains the currency exposure of the underlying equity investments.

The Fund may purchase other types of securities, for example: American Deposi-
tory Receipts (ADRs), Global Depository Receipts (GDRs), European Depository
Receipts (EDRs), and certain derivatives (investments whose value is based on
indices or other securities).

In abnormal market conditions, the Fund may take temporary defensive measures--
such as holding unusually large amounts of cash and cash equivalents--that are
inconsistent with the Fund's primary investment strategy. In taking those mea-
sures, the Fund may not achieve its investment goal.

lack of liquidity, foreign ownership limits and restrictions on removing cur-
rency also pose special risks. All foreign securities have some degree of for-

periods of rising prices and periods of falling prices. Stocks tend to go up
and down in value more than bonds. If the Fund's investments are concentrated
in certain sectors, the Fund's performance could be worse than the overall mar-
ket.

Manager Risk: The manager and its strategy may fail to produce the intended
results. The Fund could underperform its peers or lose money if the manager's
investment strategy does not perform as expected.

Turnover Risk: In general, the greater the volume of buying and selling by a
fund (i.e., the higher its "turnover rate"), the greater the impact that bro-
kerage commissions and other transaction costs will have on the funds perfor-
mance. Any turnover rate in excess of 100% is considered relatively high. The
Fund's turnover rate could be greater than 100% due to the relatively high vol-
atility associated with investing in emerging markets.

Secondary

Derivatives Risk: Certain derivative instruments (such as options, futures and
swaps) can produce disproportionate gains or losses. They are generally consid-
ered more risky than direct equity investments. Also, in a down market, deriva-
tives could become harder to value or sell at a fair price.

Short-Term Bond Fund

GOAL AND STRATEGY

This is a short-term bond fund that seeks high income consistent with low share
price fluctuation.

The Fund primarily invests in a diversified mix of short-term and intermediate-
term investment grade debt securities including:

 . U.S. Treasury and Agency securities;

 . U.S. corporate bonds;

 . foreign corporate bonds of companies in developed countries (if dollar-
  denominated);

 . foreign government and agency securities of developed countries (if dollar
  denominated); and

 . mortgage-and asset-backed securities.

The manager selects bonds using a combination of proprietary research and quan-
titative tools. Bonds are purchased that are attractively priced and that pro-
vide cheap, predictable cash flows.

The Fund normally invests:

 . mostly in corporate bonds;

 . no more than 15% of its assets in high yield bonds; and

 . no more than 25% of its assets in foreign debt securities.

The Fund normally has:

 . an average maturity between one and three and a half years;

 . an average credit quality rating of "A" or higher; and

 . 10% or less of its assets in cash and cash equivalents.

The Fund only invests in securities that are rated at least BB- or Ba3 at time
of purchase.

The Fund may purchase other types of securities, for example: certain deriva-
tives (investments whose value is based on indexes or other securities).

In abnormal market conditions, the Fund may take temporary defensive measures--
such as holding unusually large amounts of cash and cash equivalents--that are
inconsistent with the Fund's primary investment strategy. In taking those mea-
sures, the Fund may not achieve its investment goal.

MAIN RISKS

Primary

Market Risk: The value of the securities in the Fund may go down in response
to overall stock or bond market movements. Markets tend to move in cycles,
with periods of rising prices and periods of falling prices. Stocks tend to go
up and down in value more than bonds. If the Fund's investments are concen-
trated in certain sectors, the Fund's performance could be worse than the
overall market.

Manager Risk: The manager and its strategy may fail to produce the intended
results. The Fund could underperform its peers or lose money if the manager's
investment strategy does not perform as expected.

Interest Rate Risk: When interest rates rise, the Fund's bond yields will gen-
erally rise and the Fund's bond prices will generally fall. When interest
rates fall, the reverse will generally occur. The longer the average remaining
maturity of bonds held by the Fund, the more sensitive the Fund is to interest
rate risk. This Fund has less interest rate risk than an intermediate-term or
long-term bond fund.
Credit Risk: An issuer of a bond held by the Fund may default on its obliga-
tion to pay interest and repay principal. Also, the credit rating of a bond
held by the fund may be downgraded. In either case, the value of the bond held
by the Trust would fall. All bonds have some credit risk, but in general low-
er-rated bonds have higher credit risk.

Concentration Risk: The Fund's investment in securities of a smaller number of
issuers could produce more volatile performance relative to funds that invest
in a larger number of issuers. The more concentrated a fund's holdings are,
the more likely it is a specific security's poor performance will hurt the
fund significantly.

Turnover Risk: In general, the greater the volume of buying and selling by a
fund (i.e., the higher its "turnover rate"), the greater the impact that bro-
kerage commissions and other transaction costs will have on the fund's perfor-
mance. Any turnover rate in excess of 100% is considered relatively high. Nor-
mally, the Fund's turnover rate will be greater than 100%.
Secondary

Foreign Risk: The Fund's foreign securities will pose special risks, due to
limited government regulation, lack of public information, and economic,
political and social instability. Factors such as lack of liquidity, foreign
ownership limits and restrictions on removing currency also pose special
risks.

Derivatives Risk: Certain derivative instruments (such as options, futures and
swaps) can produce disproportionate gains or losses. They are generally con-
sidered more risky than direct equity investments. Also, in a down market,
derivatives could become harder to value or sell at a fair price.

High Yield Bond Risk: Junk bonds, defined as bond securities rated below BBB-
/Baa3, may be subject to more volatile or erratic price movements due to
investor sentiment. In a down market, these high yield securities become
harder to value or to sell at a fair price.

Prepayment / Call Risk: The Fund's share price or yield could be hurt if
interest rate movements cause the Fund's mortgage-related and callable securi-
ties to be paid off substantially earlier than expected.

Bond Index Fund

GOAL AND STRATEGY

This is a bond fund that seeks to track the performance of the Lehman Brothers
Government / Corporate Bond Index.

The manager employs a passive management strategy using quantitative techniques
to select individual securities that provide a representative sample of the
securities in the Index.

If the Fund reaches approximately $50 million in total assets, the manager will
seek to match the performance of the Lehman Brothers Aggregate Bond Index, a
broader market index that also includes mortgage-backed and asset-backed secu-
rities.

Both of these Indexes consist of dollar-denominated investment grade securities
with maturities greater than one year and outstanding par values of at least
$150 million issued primarily by:

 . the U.S. Treasury and U.S. government agencies and instrumentalities;

 . foreign governments and agencies; and

 . U.S. and foreign corporations.

The manager selects securities to match, as closely as practical, the Index's
duration, cash flow, sector, credit quality, callability, and other key perfor-
mance characteristics. The Fund may hold some cash and cash equivalents, but is
normally fully invested.
The Index composition may change from time to time. The manager may keep secu-
rities that no longer meet the Index criteria as long as:

 . such "ineligible" securities plus cash and money market instruments are less
  than 20% of the Fund's assets; and

 . high yield securities are less than 5% of the Fund's assets.

MAIN RISKS

Primary

Index Management Risk:  Certain factors such as the following may cause the
Fund to track the Index less closely:

 . The securities selected by the manager may not be fully representative of the
  Index.

 . Transaction expenses of the Fund may result in the Fund's performance being
  different than that of the Index.

 . The size and timing of the Fund's cash flows may result in the Fund's perfor-
  mance being different than that of the Index.

Also, index funds like this one will have more difficulty in taking defensive
positions in abnormal market conditions.

Market Risk: The value of the securities in the Fund may go down in response to
overall stock or bond market movements. Markets tend to move in cycles, with
periods of rising prices and periods of falling prices. Stocks tend to go up
and down in value more than bonds. If the Fund's investments are concentrated
in certain sectors, the Fund's performance could be worse than the overall mar-
ket.

Manager Risk: The manager and its strategy may fail to produce the intended
results. The Fund could underperform its peers or lose money if the manager's
investment strategy does not perform as expected.

Interest Rate Risk: When interest rates rise, the Fund's bond yields will gen-
erally rise and the Fund's bond prices will generally fall. When interest rates
fall, the reverse will generally occur. The longer the average remaining matu-
rity of bonds held by the Fund, the more sensitive the Fund is to interest rate
risk. This Fund has more interest rate risk than a short-term bond fund, but
less interest rate risk than a long-term bond fund.

Credit Risk: An issuer of a bond held by the Fund may default on its obligation
to pay interest and repay principal. Also, the credit rating of a bond held by
the fund may be downgraded. In either case, the value of the bond held by the
Trust would fall. All bonds have some credit risk, but in general lower-rated
bonds have higher credit risk.

Secondary

Foreign Risk: The Fund's foreign securities will pose special risks, due to
limited government regulation, lack of public information, and economic, polit-
ical and social instability. Factors such as lack of liquidity, foreign owner-
ship limits and restrictions on removing currency also pose special risks. All
foreign securities have some degree of foreign risk. However, to the extent the
Fund invests in emerging market countries, it will have a significantly higher
degree of foreign risk than if it invested exclusively in developed or newly-
industrialized countries.

Active Bond Fund
(Formerly Sovereign Bond Fund)

GOAL AND STRATEGY

This is a bond fund that seeks income and growth in capital.

The Fund primarily invests in a diversified mix of debt securities including:

 . U.S. Treasury and agency securities;

 . foreign government and agency securities (if dollar-denominated);

 . corporate bonds, both U.S. and foreign (if dollar-denominated); and

 . mortgage-backed and asset-backed securities.

The manager normally invests:

 . mostly in investment grade debt securities;

 . no more than 25% of the Fund's assets in high yield bonds; and

 . no more than 25% of the Fund's assets in foreign securities, excluding Cana-
  dian securities.

The manager seeks to identify specific bond sectors, industries and specific
bonds that are attractively priced. The manager tries to anticipate shifts in
the business cycle, using economic and industry analysis to determine which
sectors and industries might benefit over the next 12 months. The manager uses
proprietary research to identify securities that are undervalued.

The manager evaluates bonds of all quality levels and maturities from many dif-
ferent issuers. The Fund normally has an average credit rating A or higher.

The Fund normally has 10% or less of its assets in cash and cash equivalents.
The Fund may purchase other types of securities, for example: emerging market
debt securities, and certain derivatives (investments whose value is based on
indices or other securities). The manager actively uses derivatives, such as
futures, to adjust the Fund's average maturity relative to the
Lehman Brothers Aggregate Bond Index and seeks to keep the Fund's interest rate
sensitivity in line with the overall market.

In abnormal market conditions, the Fund may take temporary defensive measures--
such as holding unusually large amounts of cash and cash equivalents--that are
inconsistent with the Fund's primary investment strategy. In taking those mea-
sures, the Fund may not achieve its investment goal.

MAIN RISKS

Primary

Market Risk: The value of the securities in the Fund may go down in response
to overall stock or bond market movements. Markets tend to move in cycles,
with periods of rising prices and periods of falling prices. Stocks tend to go
up and down in value more than bonds. If the Fund's investments are concen-
trated in certain sectors, the Fund's performance could be worse than the
overall market.

Manager Risk: The manager and its strategy may fail to produce the intended
results. The Fund could underperform its peers or lose money if the manager's
investment strategy does not perform as expected.

Interest Rate Risk: When interest rates rise, the Fund's bond yields will gen-
erally rise and the Fund's bond prices will generally fall. When interest
rates fall, the reverse will generally occur. The longer the average remaining
maturity of bonds held by the Fund, the more sensitive the Fund is to interest
rate risk. This Fund has more interest rate risk than a short-term bond fund,
but less interest rate risk than a long-term bond fund.

Credit Risk: An issuer of a bond held by the Fund may default on its obliga-
tion to pay interest and repay principal. Also, the credit rating of a bond
held by the fund may be downgraded. In either case, the value of the bond held
by the Fund would fall. All bonds have some credit risk, but in general lower-
rated bonds have higher credit risk.
Turnover Risk: In general, the greater the volume of buying and selling by a
fund (i.e., the higher its "turnover rate"), the greater the impact that bro-
kerage commissions and other transaction costs will have on the fund's perfor-
mance. Any turnover rate in excess of 100% is considered relatively high. Nor-
mally, the Fund's turnover rate will be greater than 100%.

Secondary

Foreign Risk: The Fund's foreign securities will pose special risks, due to
limited government regulation, lack of public information, and economic,
political and social instability. Factors such as lack of liquidity, foreign
ownership limits and restrictions on removing currency also pose special
risks. All foreign securities have some degree of foreign risk. However, to
the extent the Fund invests in emerging market countries, it will have a sig-
nificantly higher degree of foreign risk than if it invested exclusively in
developed or newly-industrialized countries.

Derivatives Risk: Certain derivative instruments (such as options, futures and
swaps) can produce disproportionate gains or losses. They are generally con-
sidered more risky than direct equity investments. Also, in a down market,
derivatives could become harder to value or sell at a fair price.

High Yield Bond Risk: Junk bonds, defined as bond securities rated below BBB-
/Baa3, may be subject to more volatile or erratic price movements due to
investor sentiment. In a down market, these high yield securities become
harder to value or to sell at a fair price.

Prepayment/Call Risk: The Fund's share price or yield could be hurt if inter-
est rate movements cause the Fund's mortgage-related and callable securities
to be paid off substantially earlier than expected.

Global Bond Fund

GOAL AND STRATEGY

This is a global bond fund that seeks income and growth in capital.

The Fund primarily invests in a mix of debt securities of developed countries
throughout the world including:

 . U.S. Treasury and agency securities;

 . foreign government and agency securities;

 . supranational securities (such as the World Bank);

 . corporate bonds, both U.S. and foreign; and

 . mortgage-backed and asset-backed securities.

The manager makes ongoing decisions regarding the Fund's mix of U.S. bonds and
non-U.S. bonds (denominated in foreign currencies). The manager has a target
mix of 35% U.S. bonds and 65% non-U.S. bonds, but actively manages the mix
within (+/-) 50 percentage points of the target mix.

The Fund invests in at least 3 countries, but normally in 5 to 15 countries.
The Fund normally has an average credit quality rating of "AA" or higher.

The manager makes ongoing decisions regarding the Fund's average maturity,
country and sector allocations and foreign currency exposures. The manager uses
proprietary research and economic analysis to try to anticipate market condi-
tions and interest rate movements and to purchase securities that appear com-
paratively undervalued.

The manager actively uses derivatives (investments whose value is based on
indices or other securities) such as futures, forwards, options and swaps to
adjust the Fund's average maturity and to implement currency strategies. The
Fund is typically 75% to 100% hedged to the U.S. dollar.

The manager actively uses cash and cash equivalents to manage the Fund's aver-
age maturity. However, the Fund normally invests 20% or less of its assets in
cash and cash equivalents.

The Fund may purchase other types of securities, for example: high yield debt
securities and emerging market debt securities.

In abnormal market conditions, the Fund may take temporary defensive measures--
such as holding unusually large amounts of cash and cash equivalents--that are
inconsistent with the Fund's primary investment strategy. In taking those mea-
sures, the Fund may not achieve its investment goal.

MAIN RISKS

Primary

Foreign Risk: The Fund's foreign securities will pose special risks, due to
limited government regulation, lack of public information, economic, political
and social instability and foreign currency rate fluctuations. Factors such as
lack of liquidity, foreign ownership limits and restrictions on removing cur-
rency also pose special risks. All foreign securities have some degree of for-
eign risk. However, the Fund's investments in emerging market countries have a
significantly higher degree of foreign risk than investments in developed or
newly-industrialized countries.

Market Risk: The value of the securities in the Fund may go down in response to
overall stock or bond market movements. Markets tend to move in cycles, with
periods of rising prices and periods of falling prices. Stocks tend to go up
and down in value more than bonds. If the Fund's investments are concentrated
in certain sectors, the Fund's performance could be worse than the overall mar-
ket.

Manager Risk: The manager and its strategy may fail to produce the intended
results. The Fund could underperform its peers or lose money if the manager's
investment strategy does not perform as expected.

Interest Rate Risk: When interest rates rise, the Fund's bond yields will gen-
erally rise and the Fund's bond prices will generally fall. When interest rates
fall, the reverse will generally occur. The longer the average remaining matu-
rity of bonds held by the Fund, the more sensitive the Fund is to interest rate
risk. This Fund has more interest rate risk than a short-term bond fund, but
less interest rate risk than a long-term bond fund.

Credit Risk: An issuer of a bond held by the Fund may default on its obligation
to pay interest and repay principal. Also, the credit rating of a bond held by
the fund may be downgraded. In either case, the value of the bond held by the
Trust would fall. All bonds have some credit risk, but in general lower-rated
bonds have higher credit risk.

Concentration Risk: The Fund's investment in securities of a smaller number of
issuers could produce more volatile performance relative to funds that invest
in a larger number of issuers. The more concentrated a fund's holdings are, the
more likely it is a specific securities poor performance will hurt the fund
significantly.

Turnover Risk: In general, the greater the volume of buying and selling by a
fund (i.e., the higher its "turnover rate"), the greater the impact that bro-
kerage commissions and other transaction costs will have on the fund's perfor-
mance. Any turnover rate in excess of 100% is considered relatively high. Nor-

tives could become harder to value or sell at a fair price.

High Yield Bond Fund

GOAL AND STRATEGY

This is a high yield bond fund that seeks high income and growth in capital.

The Fund invests primarily in a diversified mix of high yield debt securities,
commonly referred to as "junk bonds" (rated BB+/Ba1 or lower and their unrated
equivalents), including:

 . corporate bonds, both U.S. and foreign (if dollar-denominated);

 . foreign government and agency securities (if dollar-denominated);

 . preferred stocks; and

 . convertible securities (convertible into common stocks or other equity inter-
  ests).

The manager will invest no more than 15% of the Fund's assets in emerging mar-
ket countries (with below investment-grade sovereign debt). The Fund normally
has 10% or less of its assets in cash and cash equivalents.

The manager seeks to purchase bonds with stable or improving credit quality
before the market widely perceives the improvement. Purchase and sale decisions
are primarily based upon the investment merits of the particular security.

The manager selects bonds using proprietary research, including:

 . quantitative analysis of historical financial data;

 . qualitative analysis of a company's future prospects; and

 . economic and industry analysis.

The Fund's average maturity depends on security selection decisions rather than
interest rate decisions.

The Fund may purchase other types of securities, for example: equity securi-
ties, high quality debt securities (short-term and otherwise), certain deriva-
tives (investments whose value is based on indices or other securities), and
debt securities denominated in foreign currencies.

In abnormal market conditions, the Fund may take temporary defensive measures--
such as holding unusually large amounts of cash and cash equivalents--that are
inconsistent with the Fund's primary investment strategy. In taking those mea-
sures, the Fund may not achieve its investment goal.

periods of rising prices and periods of falling prices. Stocks tend to go up
and down in value more than bonds. If the Fund's investments are concentrated

investment strategy does not perform as expected.
Interest Rate Risk: When interest rates rise, the Fund's bond yields will gen-
erally rise and the Fund's bond prices will generally fall. When interest rates
fall, the reverse will generally occur. The longer the average remaining matu-
rity of bonds held by the Fund, the more sensitive the Fund is to interest rate
risk. This Fund has more interest rate risk than a short-term bond fund, but
less interest rate risk than a long-term bond fund.

Credit Risk: An issuer of a bond held by the Fund may default on its obligation
to pay interest and repay principal. Also, the credit rating of a bond held by
the fund may be downgraded. In either case, the value of the bond held by the
Fund would fall. All bonds have some credit risk, but in general lower-rated
bonds have higher credit risk.

Secondary

Foreign Risk: The Fund's foreign securities will pose special risks, due to
limited government regulation, lack of public information, and economic, polit-
ical and social instability. Factors such as lack of liquidity, foreign owner-
ship limits and restrictions on removing currency also pose special risks. All
foreign securities have some degree of foreign risk. However, to the extent the

ered more risky than direct equity investments. Also, in a down market, deriva-
tives could become harder to value or sell at a fair price.

Prepayment/Call Risk: The Fund's share price or yield could be hurt if interest
rate movements cause the Fund's mortgage-related and callable securities to be
paid off substantially earlier than expected.

Money Market Fund

GOAL AND STRATEGY

This is a money market fund that seeks current income consistent with maintain-
ing liquidity and preserving capital. The Fund intends to maintain a stable net
asset value of $10 per share.

The Fund only invests in U.S. dollar denominated money market instruments rated
within the two highest short-term credit rating categories, primarily includ-
ing:

 . commercial paper;

 . asset-backed commercial paper;

 . bank notes and certificates of deposit;

 . short-term bonds;

 . U.S. Treasury and agency notes and bills; and

 . repurchase and reverse repurchase agreements.

These securities have a maximum remaining maturity of 397 days (13 months) and
may be issued by:

 . U.S. and foreign banks and other lending institutions;

 . U.S. and foreign corporations;

 . the U.S. Treasury and U.S. government agencies and instrumentalities;

 . entities whose obligations are guaranteed as to principal or interest by the
  U.S. Government;

 . municipalities;

 . foreign governments; and

 . supranational organizations (such as the World Bank).

The weighted average time to maturity of the Fund's investments is 90 days or
less.

The manager may invest:

 . up to 5% of assets in securities rated in the second-highest short-term cate-
  gory (or unrated equivalents); and

 . up to 1% of assets or $1 million (whichever is greater) in securities of a
  single issuer rated in the second-highest short-term category (or unrated
  equivalents).

The manager selects securities with the highest yield available among securi-
ties of comparable credit quality and maturity using proprietary research.

PAST PERFORMANCE

The graph shows how the fund's total return has varied from year to year, while
the table shows performance over time. This information may also help provide
an indication of the fund's risks and potential rewards. All figures assume
dividend reinvestment. Past performance does not indicate future results. The
performance figures below do not reflect the deduction of fees and charges
payable under the variable contracts. Such fees and charges would cause the
investment returns under the contracts to be less than that shown below.

MAIN RISKS

Primary

Manager Risk: The manager and its strategy may fail to produce the intended
results. The Fund could underperform its peers or lose money if the manager's
investment strategy does not perform as expected.

Interest Rate Risk: When interest rates rise, yields on the Fund's investments
will generally rise and prices on the Fund's investments will generally fall.
When interest rates fall, the reverse will generally occur. The longer the
average remaining maturity of instruments held by the Fund, the more sensitive
the Fund is to interest rate risk. This Fund has less interest rate risk than
an intermediate-term or long-term bond fund.

Credit Risk: An issuer of an instrument held by the Fund may default on its
obligation to pay interest and repay principal. Also, the credit rating of an
instrument held by the Fund may be downgraded. In either case, the value of the
instrument held by the Fund would fall. All money market instruments have some
credit risk, but in general lower-rated instruments have higher credit risk.
Foreign Risk: The Fund's foreign securities will pose special risks, due to
limited government regulation, lack of public information, and economic, polit-
ical and social instability. Factors such as lack of liquidity, foreign owner-
ship limits and restrictions on removing currency also pose special risks. All
foreign securities have some degree of foreign risk. However, to the extent the
Fund invests in emerging market countries, it will have a significantly higher
degree of foreign risk than if it invested exclusively in developed or newly-
industrialized countries.

Your Account

Investments in shares of the funds

Each fund sells its shares directly to separate accounts of John Hancock,
JHVLICO and IPL to fund variable contracts. Each fund also buys back its shares
on redemption by the separate accounts.

Under the variable contracts, a separate account buys or redeems a fund's
shares based on:

 . instructions by you and other contractowners to invest or receive back monies
  under a contract (such as making a premium payment or surrendering a con-
  tract), and

 . the operation of a contract (such as deduction of fees and charges).

The Trust, as law permits, may:

 . refuse a buy order if the adviser believes it would disrupt management

 . suspend a fund's offer of shares, or

 . suspend a fund's redemption obligation or postpone a fund's payment of
  redemption proceeds for more than seven days.

Share price

Each fund sells and buys back its shares at the net asset value per share
("NAV") next computed after receipt by a separate account of a contractowner's
instructions.

Each fund calculates its NAV:

 . by dividing its net assets by the number of its outstanding shares,

 . once daily as of the close of regular trading on the New York Stock Exchange
  (generally at 4 p.m. New York time) on each day the Exchange is open.

Certain funds may hold securities primarily listed on foreign exchanges that
trade on weekends or other days when the Trust does not calculate NAV. Conse-
quently, NAV may change on days when contractowners will not be able to
instruct a separate account to buy or redeem fund shares.

Valuation

The Money Market Fund values its securities at amortized cost. Each of the
other funds values securities based on:

 . market quotations,

 . amortized cost,

 . valuations of independent pricing services, or

 . fair value determined in accordance with procedures approved by the Trust's
  trustees.

A fund may value securities at fair value where, for example:

 .market quotations are not readily available, or

 . the value of securities has been materially affected after the closing of a
  foreign market.

Conflicts

The Trust's trustees monitor for possible material irreconcilable conflicts
among separate accounts buying shares of the funds. The Trust's net asset value
could decrease, if the Trust had to sell investment securities to pay redemp-
tion proceeds to a separate account withdrawing because of a conflict.

The adviser pays subadvisory fees out of its own assets. No fund pays a fee to
its subadviser.

The adviser has agreed to limit each fund's annual expenses (excluding advisory
fees and certain other expenses such as brokerage and taxes) to not more than
 .10 percent of the fund's average daily net assets.
Dividends and Taxes

Dividends

Each fund automatically reinvests its dividends and distributions in additional
shares of the fund at NAV.

Each fund declares and pays dividends monthly, except that the Money Market
Fund does so daily.

Funds generally declare capital gains distributions annually.

Taxes

Each fund must meet investment diversification and other requirements under the
Internal Revenue Code, in order to:

 . avoid federal income tax and excise tax, and

 . assure the tax-deferred treatment of variable contracts under the Code.

You should read the prospectus for your variable contract for the federal
income tax consequences for contractowners, including the consequences of a
fund's failure to meet Code requirements.

APPENDIX

Additional Performance Information

The "Past Performance" information shown earlier in this prospectus for certain
of the Funds may not be sufficient for you to make a complete assessment of the
risks and potential rewards of investing in those Funds. The Large Cap Aggres-
sive Growth Fund only began operations on August 31, 1999. The Small/Mid Cap
CORE Fund, the Emerging Markets Equity Fund, the Bond Index Fund, and the High
Yield Bond Fund only began operations on May 1, 1998. The Small/Mid Cap Growth
Fund and the Global Bond Fund each implemented a significant change in strategy
as of May 1, 1999. Finally, the Global Balanced Fund implemented a significant
change in strategy as of May 1, 2000.

Since each of these Funds has at best a very limited period of relevant perfor-
mance history, we have set forth below information for certain similar accounts
that are managed by the Funds' respective subadvisers. Each grouping of such
accounts is referred to as a "composite." In the case of each account included
in a composite, the total management fees and other operating expenses of the
Fund (based upon management fee schedules and allocation rules currently in
effect) have been substituted for the actual fees and expenses (other than bro-
kerage and other transaction expenses) of the account. Also, except as specifi-
cally noted below, each composite includes all of the investment company and
other accounts of the subadviser that satisfy the following requirements:

 . they have been managed with investment objectives, policies, and strategies
  substantially similar to those used in managing the Fund, and

 . they are of sufficient size that their performance would be considered rele-
  vant to the owner of a variable contract investing in that Fund.

Some of the accounts in the composites were not registered investment companies
and, therefore, were not subject to federal income tax and other legal require-
ments applicable to such companies. Had such accounts been subject to such
requirements, their performance could have been adversely affected. The perfor-
mance figures in this Appendix do not reflect the deduction of fees and charges
payable under the variable contracts. Such fees and charges would cause the
investment returns under the contacts to be less than that shown below.

The graphs below show how the composite's total return has varied from year to
year, while the tables show performance over time (along with a broad-based
index for reference). All figures assume dividend reinvestment. Past perfor-
mance does not indicate future results.

Large Cap Aggressive Growth Composite (Corresponding to Large Cap Aggressive
Growth Fund)

The Large Cap Aggressive Growth Composite is an asset-weighted composite of all
fully discretionary accounts (excluding mutual funds) managed using a substan-
tially similar investment strategy. As of December 31, 1999, the composite
included 245 accounts with total assets of $47.8 billion.

Overview

FUND INFORMATION KEY
Concise fund-by-fund descriptions begin on page 6. Each description provides
the following information:

Goal and Strategy The fund's particular investment goals and the principal
strategies it intends to use in pursuing those goals.

Subadviser/Manager The firm and individual(s) providing investment management
services to the fund.

Past Performance The fund's total return, measured year-by-year and over time.

Main Risks The significant risk factors associated with the fund. The risks are
categorized as "Primary" or "Secondary". The Primary Risks are considered major
factors in the fund's performance and are described first. The Secondary Risks
are not considered major factors in the fund's performance because the fund
would not normally commit a large portion of its assets to the investments
involved. However, the Secondary Risks are of such a nature that they could
significantly affect the fund's performance, even if the investments are held
in relatively small amounts.

Financial Highlights The fund's operating performance per share, measured year-
by-year.
THE FUNDS
The Trust offers investment choices, or funds, for the variable annuity and
variable life insurance contracts ("variable contracts") of:

 . John Hancock Life Insurance Company ("John Hancock"),

 . John Hancock Variable Life Insurance Company ("JHVLICO"), and

 . Investors Partner Life Insurance Company and its subsidiaries ("IPL").

In some variable contract forms, the Trust is referred to as the "Fund" or "Se-
ries Fund" and the investment choices are referred to as "Portfolios."

RISKS OF FUNDS
These funds, like all mutual funds, are not bank deposits. They are not insured
or guaranteed by the FDIC or any other government agency. You could lose money
by investing in these funds. So, be sure to read all risk disclosure carefully
before investing.

MANAGEMENT
John Hancock is the investment adviser of each fund. John Hancock is a Massa-
chusetts stock life insurance company. On February 1, 2000, John Hancock
changed its form of organization and its name. Prior to that date, it was John
Hancock Mutual Life Insurance Company, a mutual life insurance company that was
chartered in 1862. At the end of 1999, John Hancock managed approximately $127
billion, of which it owned over
$71 billion. Most of the funds have subadvisers.

                                                                               1

Your Investment Choices

- --------------------------------------------------------------------------------
The Trust offers a number of investment choices, or funds, to suit a variety of
objectives under variable contracts. There are 31 funds available under your
variable contract. Each fund has its own strategy and its own risk/reward
profile.The funds can be broadly categorized as equity funds, balanced funds,
bond funds, and international/global funds. Within these broad categories, the
funds can be further categorized as follows:

Equity Funds
Equity funds can be categorized in two ways--by capitalization and by invest-
ment style.

Capitalization             Equity funds can be categorized by market capital-
                           ization, which is defined as the market value of
                           all shares of a company's stock. The following def-
                           initions for large, mid and small cap are based
                           upon statistics at year-end 1999, but are adjusted
                           periodically with broad equity market movements as
                           represented by the Russell 3000(R) Index or other
                           widely- recognized source of market capitalization
                           data. Adjustments are typically made on a quarterly
                           basis, but in extraordinary circumstances may be
                           made as frequently as monthly.

                           Large Cap Funds:
 . Growth & Income Fund     These funds invest in large, well-established com-
                           panies that typically are very actively traded and
 . Equity Index Fund        provide more stable investment returns over time.
                           Large cap companies represent the 300 largest
 . Large Cap Value Fund     stocks in the Russell 3000(R) Index. Each of those
                           companies has a market capitalization greater than
 . Large Cap Value CORE     $7.9 billion as of the end of 1999. Large cap funds
                           are appropriate for investors who want the least

                           equity markets.
 . Large Cap Aggressive

                           Large/Mid Cap Funds:
 . Large/Mid Cap Value Fund These funds invest in large cap and mid cap compa-
                           nies. The capitalization of these funds can shift
                           over time from primarily large cap to primarily mid
                           cap or vice versa depending on where the manager
                           identifies investment opportunities. These funds
                           are generally more volatile than pure large cap
                           funds, but generally less volatile than pure mid
                           cap funds.

                           Mid Cap Funds:
 . Mid Cap Blend            These funds invest in medium-sized, less estab-
                           lished companies that are less actively traded and
 . Mid Cap Value Fund       provide more share price volatility over time than
                           large cap stocks. Mid cap companies represent the
 . Mid Cap Growth Fund      250th to 1000th largest stocks in the Russell
                           3000(R) Index. Each of those companies has a market
 . Fundamental Mid Cap      capitalization between $1.4 billion and $9.7 bil-
  Growth                   lion as of the end of 1999. Mid cap funds are
                           appropriate for investors who are willing to accept
 . Real Estate Equity Fund  more volatile investment returns within the overall
                           equity markets with the potential reward of higher
                           long-term returns.


                           Small/Mid Cap Funds:
 . Small/Mid Cap CORE Fund  These funds invest in mid cap and small cap compa-
                           nies. The capitalization of these funds can shift
 . Small/Mid Cap Value Fund over time from primarily mid cap to primarily small
                           cap or vice versa depending on where the manager

  Fund                     are generally more volatile than pure mid cap
                           funds, but generally less volatile than pure small
                           cap funds.

                           Small Cap Funds:

                           panies that are less actively traded and have a

                           Small cap companies represent the 2000 smallest
                           stocks in the Russell 3000(R) Index. Each of these
                           companies has a market capitalization of less than
                           $1.4 billion as of the end of 1999. Small cap funds
                           are appropriately for investors who are willing to
                           accept the most volatile investment returns within
                           the overall equity markets for the potential reward
                           of higher long-term returns.

Bond Funds
Bond funds can be categorized in two ways--by average maturity and by credit
quality:

Average Maturity           Bond maturity is a key measure of interest rate
                           risk. A bond's maturity measures the time remaining
                           until the bond matures, or until the repayment of
                           the bond's principal comes due. The longer a bond's
                           maturity, the more sensitive the bond's price is to
                           changes in interest rates.

                                                                              3

                           Short:
 . Money Market Fund        These funds invest primarily in bonds with short
                           maturities, typically less than four years. These
 . Short Term Bond          funds have less interest rate risk than intermedi-
  Fund                     ate-term bond funds.

                           Intermediate:

 . Bond Index Fund          These funds invest in bonds of all maturities and
                           maintain an average maturity which is typically
 . Active Bond Fund         between four and ten years. These funds have more
                           interest rate risk than short-term bond funds.
 . Global Bond Fund

 . High Yield Bond
  Fund

Credit Quality             Credit quality is a measure of the ability of a
                           bond issuer to meet its financial obligations and
                           repay principal and interest. High quality bonds
                           have less credit risk than lower quality bonds.
                           Investment grade bonds typically have "high" or

                           High:
 . Money Market Fund        These funds focus on the highest-rated, most

                           Medium:
 . Short Term Bond          These funds invest in bonds of all credit quality
  Fund                     levels with a focus on high-rated investment grade
                           bonds. These funds typically maintain an average
 . Active Bond Fund         credit quality rating of A or BBB/Baa.

                           Low:
 .  High Yield Bond         These funds invest primarily in lower rated bonds--
   Fund                    known as high yield or "junk" bonds. These funds

International/Global Equity Funds
International funds invest primarily in securities markets outside the United
States. Global funds invest both in the United States and abroad. These funds
can be categorized by the types of markets they invest in.

                           Developed Markets:
 . Global Equity Fund       These funds invest primarily in the larger, well-
                           established developed or industralized markets
 . International            around the world. These funds have less foreign
  Equity Index Fund        securities risk than emerging market funds.

  Equity Fund              emerging markets and have more foreign securities
                           risk than funds that invest primarily in well-

In the following pages, any fund investment strategy that is stated as a per-
centage of a fund's assets applies at all times, not just at the time the fund
buys or sells an investment security. The trustees of the Trust can change the
investment goals and stragtegy of any fund without shareholder (i.e.,
contractowner) approval.

The financial highlights tables on the following pages detail the historical
performance of each fund, including total return information showing the
increase or decrease of an investment in the fund each year (assuming reinvest-
ment of all dividends and distributions). The "total investment return" shown
for each fund does not reflect the expenses and charges of the applicable sepa-
rate accounts and variable contracts. Those expenses and charges vary consider-
ably from contract to contract and are described in the variable contract pro-
spectus to which this prospectus is attached. If the earliest period shown in
the financial highlights table is less than a full calendar year, the two "Ra-
tios" shown for that period have been annualized (i.e., projected as if the
fund had been in effect for a full year). However, the "total investment
return" and "turnover rate" for that period have not been annualized.

In this prospectus, the term "stock"' is used as a shorthand reference for
equity investments generally and the term "bond" is used as a shorthand refer-
ence for debt obligations generally.

                                                                               5

Managed Fund

GOAL AND STRATEGY

This is a balanced stock and bond fund that seeks long-term growth in income
and capital.

The Fund invests primarily in a diversified mix of:

 . common stocks of large established U.S. companies;

 . bonds with maturities generally greater than 12 months; and

 . money market and other short-term debt securities with maturities generally
  not greater than 12 months.

The manager makes ongoing decisions about the mix between stocks and bonds. The
Manager has a target mix of 60% in equities and 40% in bonds, but actively man-
ages the mix within (+/-) 10 percentage points of the target mix.

The manager selects stocks and bonds using a combination of proprietary
research and quantitative tools. Stocks are purchased that are undervalued rel-
ative to the stock's history and have improving earnings growth prospects.
Bonds are purchased that are attractively priced and have cheap, predictable
cash flows. The Fund is managed using risk control techniques that maintain
risk and industry characteristics similar to the overall market.

The Fund normally invests its equity portion in 80 to 150 stocks, with at least
65% (usually higher) of its equity assets in large cap companies. The Fund may
invest up to 20% of its bond assets in foreign debt securities of developed
countries (denominated in foreign currencies) and up to 15% of its bond assets
in high yield bonds. The Fund normally has 5% or less of its assets in cash and
cash equivalents.

The Fund may purchase other types of securities, for example: American
Depository Receipts (ADRs), and certain derivatives (investments whose value is
based on indices or other securities). The manager actively uses derivatives,
such as futures and forwards, to adjust the Fund's average maturity relative to
the Lehman Brothers Aggregate Bond Index and to implement currency strategies.

In abnormal market conditions, the Fund may take temporary defensive measures--
such as holding unusually large amounts of cash and cash equivalents--that are
inconsistent with the Fund's primary investment strategy. In taking those mea-
sures, the Fund may not achieve its investment goal.

PAST PERFORMANCE

The graph shows how the fund's total return has varied from year to year, while
the table shows performance over time (along with a broad-based market index
for reference). This information may also help provide an indication of the
fund's risks and potential rewards. All figures assume dividend reinvestment.
Past performance does not indicate future results. The performance figures
below do not reflect the deduction of fees and charges payable under the
variable contracts. Such fees and charges would cause the investment returns
under the contracts to be less than that shown below.

MAIN RISKS
Primary


Market Risk: The value of the securities in the Fund may go down in response
to overall stock or bond market movements. Markets tend to move in cycles,
with periods of rising prices and periods of falling prices. Stocks tend to go
up and down in value more than bonds. If the Fund's investments are concen-
trated in certain sectors, the Fund's performance could be worse than the
overall market.


Manager Risk: The manager and its strategy may fail to produce the intended
results. The Fund could underperform its peers or lose money if the manager's
investment strategy does not perform as expected.


Investment Category Risk: The returns of the Fund's specific equity investment
category may lag the returns of the overall stock market. For example, the
Fund's "large cap" approach carries the risk that in certain markets large cap
stocks will underperform mid cap and small cap stocks.


Interest Rate Risk: When interest rates rise, the Fund's bond yields will gen-
erally rise and the Fund's bond prices will generally fall. When interest
rates fall, the reverse will generally occur. The longer the average remaining
maturity of bonds held by the Fund, the more sensitive the Fund is to interest
rate risk. This Fund has more interest rate risk than a short-term bond fund,
but less interest rate risk than a long-term bond fund.


Credit Risk: An issuer of a bond held by the Fund may default on its obliga-
tion to pay interest and repay principal. Also, the credit rating of a bond
held by the fund may be downgraded. In either case, the value of the bond held
by the Trust would fall. All bonds have some credit risk, but in general low-
er-rated bonds have higher credit risk.


Market Allocation Risk: The allocation of the Fund's assets among major asset
classes (i.e., stocks, bonds, and short-term debt securities) may (1) reduce
the Fund's holdings in a class whose value then increases unexpectedly, or (2)
increase the Fund's holdings in a class just prior to its experiencing a loss
of value.


Turnover Risk: In general, the greater the volume of buying and selling by a
fund (i.e., the higher its "turnover rate"), the greater the impact that bro-
kerage commissions and other transaction costs will have on the fund's perfor-
mance. Any turnover rate in excess of 100% is considered relatively high. Nor-
mally, the Fund's turnover rate will be greater than 100%.
Secondary


Foreign Risk: The Fund's foreign securities will pose special risks, due to
limited government regulation, lack of public information, economic, political
and social instability and foreign currency rate fluctuations. Factors such as
lack of liquidity, foreign ownership limits and restrictions on removing cur-
rency also pose special risks.


Derivatives Risk: Certain derivative instruments (such as options, futures and
swaps) can produce disproportionate gains or losses. They are generally con-
sidered more risky than direct equity investments. Also, in a down market,
derivatives could become harder to value or sell at a fair price.


High Yield Bond Risk: Junk bonds, defined as bond securities rated below BBB-
/Baa3, may be subject to more volatile or erratic price movements due to
investor sentiment. In a down market, these high yield securities become
harder to value or to sell at a fair price.


Prepayment/Call Risk: The Fund's share price or yield could be hurt if inter-
est rate movements cause the Fund's mortgage-related and callable securities
to be paid off substantially earlier than expected.

Growth & Income Fund

GOAL AND STRATEGY

This is a large cap stock fund that seeks long-term growth in income and capi-
tal.

The Fund invests primarily in a diversified mix of common stocks of large
established U.S. companies that are believed to offer:

 . favorable prospects for increasing dividends and growth in capital (i.e.,
  "value" companies); or

 . above-average potential for growth in revenues and earnings (i.e., "growth"
  companies).

The manager selects stocks using a combination of proprietary equity research
and quantitative tools. Stocks are purchased that are undervalued relative to
the stock's history and have improving earnings growth prospects. The Fund is
managed using risk control techniques that maintain risk and industry charac-
teristics similar to the S&P 500 Index.

The Fund normally invests in 80 to 150 stocks, with at least 65% (usually high-
er) of its assets in large cap companies. The Fund normally has 5% or less of
its assets in cash and cash equivalents.

The Fund may purchase other types of securities, for example: American Deposi-
tory Receipts (ADRs).

In abnormal market conditions, the Fund may take temporary defensive measures--
such as holding unusually large amounts of cash and cash equivalents--that are
inconsistent with the Fund's primary investment strategy. In taking those mea-
sures, the Fund may not achieve its investment goal.

PAST PERFORMANCE

The graph shows how the fund's total return has varied from year to year, while
the table shows performance over time (along with a broad-based market index
for reference). This information may also help provide an indication of the
fund's risks and potential rewards. All figures assume dividend reinvestment.
Past performance does not indicate future results. The performance figures
below do not reflect the deduction of fees and charges payable under the
variable contracts. Such fees and charges would cause the investment returns
under the contracts to be less than that shown below.

MAIN RISKS

Primary

Market Risk: The value of the securities in the Fund may go down in response to
overall stock or bond market movements. Markets tend to move in cycles, with
periods of rising prices and periods of falling prices. Stocks tend to go up
and down in value

more than bonds. If the Fund's investments are concentrated in certain sectors,
the Fund's performance could be worse than the overall market.

Manager Risk: The manager and its strategy may fail to produce the intended
results. The Fund could underperform its peers or lose money if the manager's
investment strategy does not perform as expected.

Investment Category Risk: The returns of the Fund's specific equity investment
category may lag the returns of the overall stock market. For example, the
Fund's "large cap" approach carries the risk that in certain markets large cap
stocks will underperform mid cap and small cap stocks.

Equity Index Fund

GOAL AND STRATEGY

This is a stock fund that seeks to track the performance of the S&P 500 Index,
which emphasizes the stocks of large U.S. companies.

The manager employs a passive management strategy by normally investing in all
500 stocks included in the Index. The manager invests in each stock in roughly
the same proportion as represented in the Index.

The manager seeks to replicate as closely as possible the aggregate risk char-
acteristics and industry diversification of the Index.

The Fund normally invests in all 500 stocks in the Index, but has no predeter-
mined number of stocks that it must hold. S&P may change the composition of the
Index from time to time. The manager will reflect those changes as soon as
practical.

The Fund is normally fully invested. The manager may invest in stock index
futures to maintain market exposure and manage cash flow.

The Fund may purchase other types of securities, for example: Standard & Poor's
Depository Receipts (SPDRs), American Depository Receipts (ADRs), cash equiva-
lents, and certain derivatives (investments whose value is based on indices or
other securities).

Index. "Standard & Poor's", "S&P" and "S&P 500" are trademarks of McGraw Hill,

MAIN RISKS

Primary

Index Management Risk:  Certain factors such as the following may cause the
Fund to track the Index less closely:

 . The securities selected by the manager may not be fully representative of
  the Index.

 . Transaction expenses of the Fund may result in the Fund's performance being
  different than that of the Index.

 . The size and timing of the Fund's cash flows may result in the Fund's per-
  formance being different than that of the Index.
Also, index funds like this one will have more difficulty in taking defensive
positions in abnormal market conditions.

Market Risk: The value of the securities in the Fund may go down in response
to overall stock or bond market movements. Markets tend to move in cycles,
with periods of rising prices and periods of falling prices. Stocks tend to go
up and down in value more than bonds. If the Fund's investments are concen-
trated in certain sectors, the Fund's performance could be worse than the
overall market.

Manager Risk: The manager and its strategy may fail to produce the intended
results. The Fund could underperform its peers or lose money if the manager's
invest-ment strategy does not perform as expected.

Investment Category Risk: The returns of the Fund's specific equity investment
category may lag the returns of the overall stock market. For example, the
Fund's "large cap" approach carries the risk that in certain markets large cap
stocks will underperform mid cap and small cap stocks.

Secondary

Derivatives Risk: Certain derivative instruments (such as options, futures and
swaps) can produce disproportionate gains or losses. They are generally con-
sidered more risky than direct equity investments. Also, in a down market,
derivatives could become harder to value or sell at a fair price.

Large Cap Value Fund

GOAL AND STRATEGY

This is a large cap stock fund with a value emphasis that seeks long-term
growth in capital and substantial dividend income.

The Fund invests primarily in a diversified mix of common stocks of large
established U.S. companies that are believed to offer favorable prospects for
increasing dividends and growth in capital.

The manager employs a value approach in selecting stocks using proprietary
equity research. Stocks are purchased that are undervalued by various measures
such as the stock's current price relative to its earnings potential.

The manager looks for companies with:

 . established operating history;

 . above-average dividend yield relative to the S&P 500 Index;

 . low price/earnings ratio relative to the S&P 500 Index;

 . sound balance sheet and other positive financial characteristics; and

 . low stock price relative to the company's underlying value.

The Fund normally invests in 100 to 175 stocks, with at least 65% (usually
higher) of its assets in large cap companies. The Fund normally has 5% or less
of its assets in cash and cash equivalents.

The Fund may purchase other types of securities, for example: American Deposi-
tory Receipts (ADRs), foreign equity securities of developed countries, high
quality intermediate and short-term debt securities, and certain derivatives
(investments whose value is based on indices or other securities).

In abnormal market conditions, the Fund may take temporary defensive measures--
such as holding unusually large amounts of cash and cash equivalents--that are
inconsistent with the Fund's primary investment strategy. In taking those mea-
sures, the Fund may not achieve its investment goal.

periods of rising prices and periods of falling prices. Stocks tend to go up
and down in value more than bonds. If the Fund's investments are concentrated

ket.

Manager Risk: The manager and its strategy may fail to produce the intended
results. The Fund could underperform its peers or lose money if the manager's
investment strategy does not perform as expected.

Investment Category Risk:  The returns of the Fund's specific equity investment
category may lag the returns of the overall stock market. For example, the
Fund's "value" approach carries the risk that in certain markets "value" stocks
will underperform "growth" stocks. Also, the Fund's "large cap" approach car-
ries the risk that in certain markets large cap stocks will underperform small
cap and mid cap stocks.

Secondary

Foreign Risk: The Fund's foreign securities will pose special risks, due to
limited government regulation, lack of public information, economic, political
and social instability and foreign currency rate fluctuations. Factors such as
lack of liquidity, foreign ownership limits and restrictions on removing cur-
rency also pose special risks.

Derivatives Risk: Certain derivative instruments (such as options, futures and
swaps) can produce disproportionate gains or losses. They are generally consid-
ered more risky than direct equity investments. Also, in a down market, deriva-
tives could become harder to value or sell at a fair price.

Large Cap Value CORE Fund

GOAL AND STRATEGY

This is a large cap stock fund with a value emphasis that seeks long-term
growth in capital and dividend income.

The Fund invests primarily in a diversified mix of common stocks of large
established U.S. companies that are believed to offer favorable prospects for
increasing dividends and growth in capital.

The manager selects stocks using a combination of quantitative techniques and
fundamental equity research. The manager employs an investment process known as
CORE, "Computer Optimized, Research-Enhanced," that employs a proprietary quan-
titative model. The manager identifies stocks that have strong expected earn-
ings growth and momentum and better valuation and risk characteristics than the
Russell 1000 Value Index.

Stocks are purchased that have:

 . Low to modest valuation characteristics relative to general market measures,
  such as price/earnings ratio, book value and other fundamental accounting
  measures, and

 . favorable prospects for capital appreciation and/or dividend paying ability.

The Fund is managed using risk control techniques to maintain risk, style, cap-
italization and industry characteristics similar to the Russell 1000(R) Value
Index. The Fund is broadly diversified by industry.

The Fund normally invests in 100 to 250 stocks, with at least 65% (usually
higher) of the Fund's assets in large cap companies. The Fund normally has 10%
or less of its assets in cash and cash equivalents.

The Fund may purchase other types of securities, for example: American Deposi-
tory Receipts (ADRs), Standard & Poor's Depository Receipts (SPDRs), and cer-
tain derivatives (investments whose value is based on indices or other securi-
ties).

In abnormal market conditions, the Fund may take temporary defensive measures--
such as holding unusually large amounts of cash and cash equivalents--that are
inconsistent with the Fund's primary investment strategy. In taking those mea-
sures, the Fund may not achieve its investment goal.

PAST PERFORMANCE

Because this Fund did not have a full year of operations as of December 31,
1999, no year-by-year total returns or average annual total returns can be
shown for this Fund. However, the Appendix to this prospectus contains certain
performance information that is relevant to this Fund. The Appendix starts on
page 71.

MAIN RISKS

Primary

Market Risk: The value of the securities in the Fund may go down in response to
overall stock or bond market movements. Markets tend to move in cycles, with
periods of rising prices and periods of falling prices. Stocks tend to go up
and down in value more than bonds. If the Fund's investments are concentrated
in certain sectors, the Fund's performance could be worse than the overall mar-
ket.

Manager Risk: The manager and its strategy may fail to produce the intended
results. The Fund could underperform its peers or lose money if the manager's
investment strategy does not perform as expected.

Investment Category Risk: The returns of the Fund's specific equity investment
category may lag the returns of the overall stock market. For example, the
Fund's "value" approach carries the risk that in certain markets "value" stocks
will underperform "growth" stocks. Also, the Fund's "large cap" approach car-
ries the risk that in certain markets large cap stocks will underperform small
and mid cap stocks.

Secondary

Derivatives Risk: Certain derivative instruments (such as options, futures and
swaps) can produce disproportionate gains or losses. They are generally consid-
ered more risky than direct equity investments. Also, in a down market, deriva-
tives could become harder to value or sell at a fair price.

Large Cap Growth Fund

GOAL AND STRATEGY

This is a large cap stock fund with a growth emphasis that seeks growth in
capital.

The Fund invests primarily in a diversified mix of common stocks of large
established U.S. companies that are believed to offer above-average potential
for growth in revenues and earnings.

The manager selects stocks using a combination of proprietary equity research
and quantitative tools. Stocks are purchased that are undervalued relative to
the stock's history and have improving earnings growth prospects. The Fund is
managed using risk control techniques that maintain risk and industry charac-
teristics similar to the Russell 1000(R) Growth Index.

The Fund normally invests in 80 to 150 stocks, with at least 65% (usually high-
er) of its assets in large cap companies. The Fund normally has 5% or less of
its assets in cash and cash equivalents.

The Fund may purchase other types of securities, for example: American Deposi-
tory Receipts (ADRs), and certain derivatives (investments whose value is based
on indices or other securities).

In abnormal market conditions, the Fund may take temporary defensive measures--
such as holding unusually large amounts of cash and cash equivalents--that are
inconsistent with the Fund's primary investment strategy. In taking those mea-
sures, the Fund may not achieve its investment goal.

PAST PERFORMANCE

The graph shows how the fund's total return has varied from year to year, while
the table shows performance over time (along with a broad-based market index
for reference). This information may help provide an indication of the fund's
risks and potential rewards. All figures assume dividend reinvestment. Past
performance does not indicate future results. The performance figures below do
not reflect the deduction of fees and charges payable under the variable
contracts. Such fees and charges would cause the investment returns under the
contracts to be less than that shown below.

Large Cap Aggressive Growth Fund

GOAL AND STRATEGY

This is a non-diversified large cap stock fund with a growth emphasis that
seeks long-term growth in capital.

The Fund invests primarily in the common stocks of large established U.S. com-
panies that are believed to offer above-average potential for long-term growth
in revenues and earnings.

The manager selects stocks using proprietary company-specific research that
focuses on firms:

 . offering superior earnings growth that is not fully reflected in current mar-
  ket valuations,

 . having prospective earnings growth rates substantially above that of the S&P
  500, and

 . exhibiting strong management, superior industry positions and excellent bal-
  ance sheets.

The Fund employs aggressive investment strategies and invests most of its asset
in a relatively small number of companies, with the 25 most highly regarded
stocks representing at least 65% of the Fund's assets. The manager selects
stocks without regard to any predefined industry or sector selection criteria.

The manager actively trades and adjusts the Fund's holdings to capitalize on
market fluctuations. The manager typically:

 . increases investment in favored securities and reduces the number of holdings
  in declining markets, and

 . decreases investment in favored securities and increases the number of hold-
  ings in rising markets.

The Fund is a non-diversified fund, which means it can take larger positions in
a smaller number of issuers. The Fund normally invests in 35 to 55 stocks, with
at least 65% (usually higher) of its assets in large cap companies. The Fund
normally has 5% or less of its assets in cash and cash equivalents.

The Fund may purchase other types of securities, for example: American Deposi-
tory Receipts (ADRs), and certain derivatives (investments whose value is based
on indices or other securities).

In abnormal market conditions, the Fund may take temporary defensive measures--
such as holding unusually large amounts of cash and cash equivalents--that are
inconsistent with the Fund's primary investment strategy. In taking those mea-
sures, the Fund may not achieve its investment goal.

MAIN RISKS

Primary

Market Risk: The value of the securities in the Fund may go down in response to
overall stock or bond market movements. Markets tend to move in cycles, with
periods of rising prices and periods of falling prices. Stocks tend to go up
and down in value more than bonds. If the Fund's investments are concentrated
in certain sectors, the Fund's performance could be worse than the overall mar-
ket.

Non-Diversified Fund Risk: The Fund's larger position in individual issuers and
in a smaller number of issuers could produce more volatile performance relative
to more diversified funds. The less diversified a fund's holdings are, the more
likely it is that a specific security's poor performance will hurt the fund
significantly.

Manager Risk: The manager and its strategy may fail to produce the intended
results. The Fund could underperform its peers or lose money if the manager's
investment strategy does not perform as expected.

Investment Category Risk: The returns of the Fund's specific equity investment
category may lag the returns of the overall stock market. For example, the
Fund's "growth" approach carries the risk that in certain markets "growth"
stocks will underperform "value" stocks. Also, the Fund's "large cap" approach
carries the risk that large cap stocks will underperform small cap and mid cap
stocks.

Concentration Risk: The Fund's investment in securities of a smaller number of
issuers could produce more volatile performance relative to funds that invest
in a larger number of issuers. The more concentrated a fund's holdings are, the
more likely it is a specific security's poor performance will hurt the fund
significantly.

Turnover Risk: In general, the greater the volume of buying and selling by a
fund (i.e., the higher its "turnover rate"), the greater the impact that bro-
kerage commissions and other transaction costs will have on the fund's perfor-
mance. Any turnover rate in excess of 100% is considered relatively high. Nor-
mally, the Fund's turnover rate will be greater than 100%.

Secondary

Derivatives Risk: Certain derivative instruments (such as options, futures and
swaps) can produce disproportionate gains or losses. They are generally consid-
ered more risky than direct equity investments. Also, in a down market, deriva-
tives could become harder to value or sell at a fair price.

Large/Mid Cap Value Fund
GOAL AND STRATEGY

This is a large/mid cap stock fund with a value emphasis that seeks long-term
growth in capital.

The Fund invests primarily in a diversified mix of common stocks of large- and
mid-sized U.S. companies that are believed to offer favorable prospects for
increasing dividends and growth in capital.

The manager employs a value approach in selecting stocks, using proprietary
equity research to identify stocks having distinct value characteristics based
on industry- specific valuation criteria.

The manager screens the investable universe for stocks with:

 . dividend yields greater than the Russell 1000(R) Value Index, and

 . price/book ratios lower than the Russell 1000(R) Value Index.

The Fund's assets are allocated to industry-specific sub-portfolios that are
managed by each industry analyst. The manager oversees the Fund to maintain
capitalization and industry weights similar to the Russell 1000(R) Value Index.

The Fund normally invests in 100 to 130 stocks, with at least 65% (usually
higher) of its assets in large and mid cap companies. The Fund normally has 5%
or less of its assets in cash and cash equivalents.

The Fund may purchase other types of securities, for example: American Deposi-
tory Receipts (ADRs), and certain derivatives (investments whose value is based
on indices or other securities).

In abnormal market conditions, the Fund may take temporary defensive measures--
such as holding unusually large amounts of cash and cash equivalents--that are
inconsistent with the Fund's primary investment strategy. In taking those mea-
sures, the Fund may not achieve its investment goal.

Small /Mid Cap Stock Risk: The Fund's investment in smaller or mid-sized compa-
nies may be subject to more erratic price movements than investment in large
established companies.

Manager Risk: The manager and its strategy may fail to produce the intended
results. The Fund could underperform its peers or lose money if the manager's
investment strategy does not perform as expected.

Investment Category Risk: The returns of the Fund's specific equity investment
category may lag the returns of the overall stock market. For example, the
Fund's "value" approach carries the risk that in certain markets "value" stocks
will underperform "growth" stocks. Also, the Fund's "large /mid cap" approach
carries the risk that large /mid cap stocks will underperform small cap stocks.

Mid Cap Blend Fund


GOAL AND STRATEGY

This is a mid cap stock fund that seeks long-term growth in capital.

The Fund invests primarily in a diversified mix of common stocks of mid-sized
U.S. companies that are believed to offer:

 . favorable prospects for increasing dividends and capital appreciation
  (i.e., "value" companies), and

 . above-average potential for growth in revenues and earnings (i.e. "growth"
  companies).

The manager selects stocks using a combination of proprietary equity research
and quantitative tools. Stocks are purchased that are undervalued relative to
the stock's history and have improving earnings growth prospects. The Fund is
managed using risk control techniques that maintain risk and industry charac-
teristics similar to the Russell Mid Cap(TM) Index.

The Fund normally invests in 100 to 150 stocks, with at least 65% (usually
higher) of its assets in mid cap companies. The Fund normally has 5% or less of
its assets in cash and cash equivalents.

The Fund may purchase other types of securities, for example: American Deposi-
tory Receipts (ADRs), and certain derivatives (investments whose value is based
on indices or other securities).

In abnormal market conditions, the Fund may take temporary defensive measures--
such as holding unusually large amounts of cash and cash equivalents--that are
inconsistent with the Fund's primary investment strategy. In taking those mea-
sures, the Fund may not achieve its investment goal.

PAST PERFORMANCE

Because this Fund did not have a full year of operations as of December 31,
1999, no year-by-year total returns or average annual total returns can be
shown for this Fund. However, the Appendix to this prospectus contains certain
performance information that is relevant to this Fund. The Appendix starts on
page 71.

MAIN RISKS

Primary

Small /Mid Cap Stock Risk: The Fund's investment in smaller or mid-sized compa-
nies may be subject to more erratic price movements than investment in large
established companies.

Market Risk: The value of the securities in the Fund may go down in response to
overall stock or bond market movements. Markets tend to move in cycles, with
periods of rising prices and periods of falling prices. Stocks tend to go up
and down in value more than bonds. If the Fund's investments are concentrated
in certain sectors, the Fund's performance could be worse than the overall mar-
ket.

Manager Risk: The manager and its strategy may fail to produce the intended
results. The Fund could underperform its peers or lose money if the manager's
investment strategy does not perform as expected.

Investment Category Risk: The returns of the Fund's specific equity investment
category may lag the returns of the overall stock market. For example, the
Fund's "mid cap" approach carries the risk that in certain markets "mid cap"
stocks will underperform "large cap" and "small cap" stocks. Also, the Fund's
"blend" style carries the risk that in certain markets, "blend" styles will
underperform "growth" and "value" styles.

Secondary

Derivatives Risk: Certain derivative instruments (such as options, futures and
swaps) can produce disproportionate gains or losses. They are generally consid-
ered more risky than direct equity investments. Also, in a down market, deriva-
tives could become harder to value or sell at a fair price.

Mid Cap Value Fund

GOAL AND STRATEGY

This is a mid cap stock fund with a value emphasis that seeks long-term growth
in capital.

The Fund invests primarily in the common stocks of mid-sized U.S. companies
that are believed to sell at a discount to their intrinsic value.

The manager selects stocks using proprietary equity research. Stocks are pur-
chased that are undervalued by various measures such as the stock's current
price relative to its earnings potential.

The manager looks for undervalued companies with:

 . sound balance sheet and other financial characteristics;

 . consistent cash flow;

 . strong position relative to the competition; and

 . high level of stock ownership among management.

The Fund normally invests in 50 to 75 stocks, with at least 65% (usually high-
er) of its assets in mid cap companies. The Fund normally has 5% or less of its
assets in cash and cash equivalents.

The Fund may purchase other types of securities, for example: American Deposi-
tory Receipts (ADRs), and certain derivatives (investments whose value is based
on indices or other securities).

In abnormal market conditions, the Fund may take temporary defensive measures--
such as holding unusually large amounts of cash and cash equivalents--that are
inconsistent with the Fund's primary investment strategy. In taking those mea-
sures, the Fund may not achieve its investment goal.

PAST PERFORMANCE

The graph shows how the fund's total return has varied from year to year, while
the table shows performance over time (along with a broad-based market index
for reference). This information may help provide an indication of the fund's
risks and potential rewards. All figures assume dividend reinvestment. Past
performance does not indicate future results. The performance figures below do
not reflect the deduction of fees and charges payable under the variable
contracts. Such fees and charges would cause the investment returns under the
contracts to be less than that shown below.

category may lag the returns of the overall stock market. For example, the
Fund's "value" approach carries the risk that in certain markets "value" stocks
will underperform "growth" stocks. Also, the Fund's "mid cap" approach carries
the risk that in certain markets mid cap stocks will underperform small cap and
large cap stocks.

Concentration Risk: The Fund's investment in securities of a smaller number of
issuers could produce more volatile performance relative to funds that invest
in a larger number of issuers. The more concentrated a fund's holdings are, the
more likely it is a specific security's poor performance will hurt the fund
significantly.

Turnover Risk: In general, the greater the volume of buying and selling by a
fund (i.e., the higher its "turnover rate"), the greater the impact that bro-
kerage commissions and other transaction costs will have on the fund's perfor-
mance. Any turnover rate in excess of 100% is considered relatively high. Nor-
mally, the Fund's turnover rate will be greater than 100%.

Secondary

Derivatives Risk: Certain derivative instruments (such as options, futures and
swaps) can produce disproportionate gains or losses. They are generally consid-
ered more risky than direct equity investments. Also, in a down market, deriva-
tives could become harder to value or sell at a fair price.

Mid Cap Growth Fund

GOAL AND STRATEGY

This is a non-diversified mid cap stock fund with a growth emphasis that seeks
long-term growth in capital.

The Fund invests primarily in the common stocks of mid-sized U.S. companies
that are believed to offer above-average potential for growth in revenues and
earnings.

The manager selects stocks using proprietary equity research. Stocks are pur-
chased that are expected to have earnings growth potential that may not be rec-
ognized by the investment community. The manager selects stocks without regard
to any pre- defined industry or sector selection criteria.

The manager looks for companies experiencing:

 . above-average growth relative to their peers or the general economy; and

 . positive change due to new product developments, improved regulatory environ-
  ment or a new management team.

The Fund is non-diversified, which means it can take larger positions in a
smaller number of issuers. Based upon its current size and strategy, the Fund
invests in 35 to 75 stocks, with at least 65% of its assets in mid cap compa-
nies. The Fund normally has 15% or less of its assets in cash and cash equiva-
lents.

The Fund may purchase other types of securities, for example: American Deposi-
tory Receipts (ADRs), foreign equity securities of developed countries, and
certain derivatives (investments whose value is based on indices or other
securities).

In abnormal market conditions, the Fund may take temporary defensive measures--
such as holding unusually large amounts of cash and cash equivalents--that are
inconsistent with the Fund's primary investment strategy. In taking those mea-
sures, the Fund may not achieve its investment goal.

MAIN RISKS

Primary

Small /Mid Cap Stock Risk: The Fund's investment in smaller or mid-sized compa-
nies may be subject to more erratic price movements than investment in large
established companies.

Non-Diversified Fund Risk: The Fund's larger position in individual issuers and
in a smaller number of issuers could produce more volatile performance relative
to more diversified funds. The less diversified a fund's holdings are, the more
likely it is that a specific security's poor performance will hurt the fund
significantly.

Market Risk: The value of the securities in the Fund may go down in response to
overall stock or bond market movements. Markets tend to move in cycles, with
periods of rising prices and periods of falling prices. Stocks tend to go up
and down in value more than bonds. If the Fund's investments are concentrated
in certain sectors, the Fund's performance could be worse than the overall mar-
ket.

Manager Risk: The manager and its strategy may fail to produce the intended
results. The Fund could underperform its peers or lose money if the manager's
investment strategy does not perform as expected.

Investment Category Risk: The returns of the Fund's specific equity investment
category may lag the returns of the overall stock market. For example, the
Fund's "growth" approach carries the risk that in certain markets "growth"
stocks will underperform "value" stocks. Also, the Fund's "mid cap" approach
carries the risk that in certain markets mid cap stocks will underperform small
cap and large cap stocks.

Concentration Risk: The Fund's investment in securities of a smaller number of
issuers could produce more volatile performance relative to funds that invest
in a larger number of issuers. The more concentrated a fund's holdings are, the
more likely it is a specific security's poor performance will hurt the fund
significantly.

Turnover Risk: In general, the greater the volume of buying and selling by a
fund (i.e., the higher its "turnover rate"), the greater the impact that bro-
kerage commissions and other transaction costs will have on the fund's perfor-
mance. Any turnover rate in excess of 100% is considered relatively high. Nor-
mally, the Fund's turnover rate will be greater than 100%.

Secondary

Foreign Risk: The Fund's foreign securities will pose special risks, due to
limited government regulation, lack of public information, economic, political
and social instability and foreign currency rate fluctuations. Factors such as
lack of liquidity, foreign ownership limits and restrictions on removing cur-
rency also pose special risks.

Derivatives Risk: Certain derivative instruments (such as options, futures and
swaps) can produce disproportionate gains or losses. They are generally consid-
ered more risky than direct equity investments. Also, in a down market, deriva-
tives could be- come harder to value or sell at a fair price.

Fundamental Mid Cap Growth Fund


GOAL AND STRATEGY

This is a mid cap stock fund with a growth emphasis that seeks long-term growth
in capital.

The Fund invests primarily in the common stocks of mid-sized U.S. companies
that are believed to offer above-average potential for growth in revenues and
earnings.

The manager selects stocks using both proprietary equity research and external
consensus earnings forecasts. Stocks are purchased that are believed to offer:

 . High rate of sustainable earnings growth of 15% plus,

 . revenue growth generated by operating results (unit volume); and

 .sustainable revenue growth of 10% plus.

The manager looks for companies with:

 . innovative management and strong leadership positions in unique market
  niches;

 . undiscovered and undervalued emerging growth opportunities; and,

 . new products and services.

The Fund's industry exposures are a result of stock selection as opposed to
predetermined allocations.

The Fund normally invests in 60 to 80 stocks, with at least 65% (usually high-
er) of its assets in mid cap companies. The Fund normally has 5% or less of its
assets in cash and cash equivalents.

The Fund may purchase other types of securities, for example: American Deposi-
tory Receipts (ADRs), and certain derivatives (investments whose value is based
on indices or other securities).

In abnormal market conditions, the Fund may take temporary defensive measures--
such as holding unusually large amounts of cash and cash equivalents--that are
inconsistent with the Fund's primary investment strategy. In taking those mea-
sures, the Fund may not achieve its investment goal.

MAIN RISKS

Primary

Small /Mid Cap Stock Risk: The Fund's investment in smaller or mid-sized compa-
nies may be subject to more erratic price movements than investment in large
established companies.

Market Risk: The value of the securities in the Fund may go down in response to
overall stock or bond market movements. Markets tend to move in cycles, with
periods of rising prices and periods of falling prices. Stocks tend to go up
and down in value more than bonds. If the Fund's investments are concentrated
in certain sectors, the Fund's performance could be worse than the overall mar-
ket.

Manager Risk: The manager and its strategy may fail to produce the intended
results. The Fund could underperform its peers or lose money if the manager's
investment strategy does not perform as expected.

Investment Category Risk: The returns of the Fund's specific equity investment
category may lag the returns of the overall stock market. For example, the
Fund's "growth" approach carries the risk that in certain markets "growth"
stocks will underperform "value" stocks. Also, the Fund's "mid cap" approach
carries the risk that mid cap stocks will underperform large cap and small cap
stocks.

Concentration Risk: The Fund's investment in securities of a smaller number of
issuers could produce more volatile performance relative to funds that invest
in a larger number of issuers. The more concentrated a fund's holdings are, the
more likely it is a specific security's poor performance will hurt the fund
significantly.

Turnover Risk: In general, the greater the volume of buying and selling by a
fund (i.e., the higher its "turnover rate"), the greater the impact that bro-
kerage commissions and other transaction costs will have on the fund's perfor-
mance. Any turnover rate in excess of 100% is considered relatively high. Nor-
mally, the Fund's turnover rate will be greater than 100%.

Secondary

Derivatives Risk: Certain derivative instruments (such as options, futures and
swaps) can produce disproportionate gains or losses. They are generally consid-
ered more risky than direct equity investments. Also, in a down market, deriva-
tives could become harder to value or sell at a fair price.

Real Estate Equity Fund

GOAL AND STRATEGY

This is a real estate stock fund that seeks above-average income and long-term
growth in capital.

The Fund invests primarily in:

 . equity securities of real estate investment trusts (REITs) that own commer-
  cial and multi-family residential real estate; and

 . equity securities of real estate operating companies (i.e., companies with at
  least 75% of revenue, income or fair asset value derived from real estate).

The manager selects real estate stocks using a combination of proprietary,
equity research and quantitative tools. Real estate stocks are purchased that
are undervalued relative to the stock's history and the market and have improv-
ing earnings growth prospects.

The manager looks for real estate stocks with:

 . proven track records,

 . strong management whose interests are aligned with shareholders,

 . attractive real estate holdings, and

 . a flexible financial structure.

The manager employs risk control techniques to maintain risk, style and indus-
try characteristics similar to the public equity real estate market. The Fund
normally invests in 30 to 60 securities. The Fund normally has 5% or less of
its assets in cash and cash equivalents.

The Fund also may purchase other types of securities, for example: American
Depository Receipts (ADRs), convertible securities, and equity securities of
non-real estate businesses whose real estate holdings are significant in rela-
tion to their market capitalization.

In abnormal market conditions, the Fund may take temporary defensive measures--
such as holding unusually large amounts of cash and cash equivalents--that are
inconsistent with the Fund's primary investment strategy. In taking those mea-
sures, the Fund may not achieve its investment goal.

PAST PERFORMANCE

The graph shows how the fund's total return has varied from year to year, while
the table shows performance over time (along with a broad-based market index
for reference). This information may help provide an indication of the fund's
risks and potential rewards. All figures assume dividend reinvestment. Past
performance does not indicate future results. The performance figures below do
not reflect the deduction of fees and charges payable under the variable
contracts. Such fees and charges would cause the investment returns under the
contracts to be less than that shown below.

MAIN RISKS

Primary

Real Estate Securities Risk: Real estate investment trusts (REITs) or other
real estate-related equity securities may be affected by changes in the value
of the underlying property owned by the trust. Mortgage REITs may be affected
by the quality of any credit extended. Other potential risks include the possi-
bility of failing to qualify for tax-free pass-through of income under the
Internal Revenue Code or failing to maintain exemption under the Investment
Company Act of 1940.

Market Risk: The value of the securities in the Fund may go down in response to
overall stock or bond market movements. Markets tend to move in cycles, with
periods of rising prices and periods of falling prices. Stocks tend to go up
and down in value more than bonds. If the Fund's investments are concentrated
in certain sectors, the Fund's performance could be worse than the overall mar-
ket.

Manager Risk: The manager and its strategy may fail to produce the intended
results. The Fund could underperform its peers or lose money if the manager's
investment strategy does not perform as expected.

Concentration Risk: The Fund's investment in securities of a smaller number of
issuers could produce more volatile performance relative to funds that invest
in a larger number of issuers. The more concentrated a fund's holdings are, the
more likely it is a specific security's poor performance will hurt the fund
significantly.

Small /Mid Cap Stock Risk: The Fund's investment in smaller or mid-sized compa-
nies may be subject to more erratic price movements than investment in large
established companies.

Small/Mid Cap CORE Fund
GOAL AND STRATEGY

This is a small/mid cap stock fund that seeks long-term growth in capital.

The Fund invests primarily in a diversified mix of the common stocks of small
and mid-sized U.S. companies that are believed to offer:

 . favorable prospects for increasing dividends and capital appreciation (i.e.,
  "value" companies); and

 . above-average potential for growth in revenues and earnings (i.e. "growth"
  companies).

The manager selects stocks using a combination of quantitative techniques and
equity research. The manager employs an investment process known as CORE, "Com-
puter Optimized, Research-Enhanced," that employs a proprietary quantitative
model. Stocks are purchased that have strong expected earnings growth and
momentum and better valuation and risk characteristics than the Russell
2500(TM) Index. The Fund is managed using risk control techniques to maintain
risk, style, capitalization and industry characteristics similar to the Russell
2500(TM) Index.

The Fund normally invests in 200 to 600 stocks, with at least 65% (usually
higher) of the Fund's assets in small cap and mid cap companies. The Fund nor-
mally has 10% or less of its assets in cash and cash equivalents.

The Fund may purchase other types of securities, for example: American Deposi-
tory Receipts (ADRs), Standard & Poor's Depository Receipts (SPDRs), and cer-
tain derivatives (investments whose value is based on indices or other securi-
ties).

In abnormal market conditions, the Fund may take temporary defensive measures--
such as holding unusually large amounts of cash and cash equivalents--that are
inconsistent with the Fund's primary investment strategy. In taking those mea-
sures, the Fund may not achieve its investment goal.

MAIN RISKS

Primary

Small /Mid Cap Stock Risk: The Fund's investment in smaller or mid-sized compa-
nies may be subject to more erratic price movements than investment in large
established companies.

Market Risk: The value of the securities in the Fund may go down in response to
overall stock or bond market movements. Markets tend to move in cycles, with
periods of rising prices and periods of falling prices. Stocks tend to go up
and down in value more than bonds. If the Fund's investments are concentrated

ket.

Manager Risk: The manager and its strategy may fail to produce the intended
results. The Fund could underperform its peers or lose money if the manager's
investment strategy does not perform as expected.

Investment Category Risk: The returns of the Fund's specific equity investment
category may lag the returns of the overall stock market. For example, the
Fund's "small/mid cap" approach carries the risk that in certain markets
small/mid cap stocks will underperform large cap stocks.

Turnover Risk: In general, the greater the volume of buying and selling by a
fund (i.e., the higher its "turnover rate"), the greater the impact that bro-
kerage commissions and other transaction costs will have on the fund's perfor-
mance. Any turnover rate in excess of 100% is considered relatively high. The
Fund had unusually high turnover in 1999 and is expected to experience similar
turnover in 2000. This higher than expected turnover is due to (i) the rela-
tively small size of the Fund, which magnifies the effect of contributions and
redemptions, and (ii) the high volatility of the market, which in 1999 resulted
in the subadviser implementing procedures to reduce the Fund's tracking risk.
Normally, the Fund's turnover rate will be less than 100%.

Secondary

Derivatives Risk: Certain derivative instruments (such as options, futures and
swaps) can produce disproportionate gains or losses. They are generally consid-
ered more risky than direct equity investments. Also, in a down market, deriva-
tives could become harder to value or sell at a fair price.

Small/Mid Cap Value Fund
GOAL AND STRATEGY

This is a small/mid cap stock fund with a value emphasis that seeks long-term
growth in capital.

The Fund invests primarily in a diversified mix of the common stocks of small
and mid-sized U.S. companies that are believed to offer favorable prospects for
capital appreciation.

The manager selects stocks using a combination of proprietary quantitative
screening tools and fundamental equity research. The manager selects stocks
that have:

 .  attractive valuation characteristics, using measures such as low price-
   /earnings and price/book ratios;

 .  strong business health, as measured by overall efficiency and profitability
   (return on assets and/or equity); and

 .  business momentum, defined as a catalyst that the manager believes will
   trigger a near-term price increase.

The Fund is broadly diversified by sector. The Fund normally invests in 70 to
150 stocks, with at least 65% (usually higher) of its assets in small and mid
cap companies. The Fund normally has 5% or less of its assets in cash and cash
equivalents.

The Fund may purchase other types of securities, for example: American Deposi-
tory Receipts (ADRs), and certain derivatives (investments whose value is based
on indices or other securities).

In abnormal market conditions, the Fund may take temporary defensive measures--
such as holding unusually large amounts of cash and cash equivalents--that are
inconsistent with the Fund's primary investment strategy. In taking those mea-
sures, the Fund may not achieve its investment goal.

PAST PERFORMANCE

Because this Fund did not have a full year of operations as of December 31,
1999, no year-by-year total returns or average annual total returns can be
shown for this Fund. However, the Appendix to this prospectus contains perfor-
mance information that is relevant to this Fund. The Appendix starts on page
71.

<PAGE>


MAIN RISKS
Primary

Small/Mid Cap Stock Risk: The Fund's investment in smaller or mid-sized compa-
nies may be subject to more erratic price movements than investment in large
established companies.

Market Risk: The value of the securities in the Fund may go down in response to
overall stock or bond market movements. Markets tend to move in cycles, with
periods of rising prices and periods of falling prices. Stocks tend to go up
and down in value more than bonds. If the Fund's investments are concentrated
in certain sectors, the Fund's performance could be worse than the overall mar-
ket.

Manager Risk: The manager and its strategy may fail to produce the intended
results. The Fund could underperform its peers or lose money if the manager's
investment strategy does not perform as expected.

Investment Category Risk: The returns of the Fund's specific equity investment
category may lag the returns of the overall stock market. For example, the
Fund's "value" approach carries the risk that in certain markets "value" stocks
will underperform "growth" stocks. Also, the Fund's "small/mid cap" approach
carries the risk that in certain markets small/mid cap stocks will underperform
large cap stocks.

Turnover Risk: In general, the greater the volume of buying and selling by a
fund (i.e., the higher its "turnover rate"), the greater the impact that bro-
kerage commissions and other transaction costs will have on the fund's perfor-
mance. Any turnover rate in excess of 100% is considered relatively high. Nor-
mally, the Fund's turnover rate will be greater than 100%.

Secondary

Derivatives Risk: Certain derivative instruments (such as options, futures and
swaps) can produce disproportionate gains or losses. They are generally consid-
ered more risky than direct equity investments. Also, in a down market, deriva-
tives could become harder to value or sell at a fair price.

Small/Mid Cap Growth Fund

GOAL AND STRATEGY

This is a small/mid cap stock fund with a growth emphasis that seeks long-term
growth in capital.

The Fund invests primarily in the common stocks of small and mid-sized U.S.
companies that are believed to offer above-average potential for growth in rev-
enues and earnings.

The manager selects stocks using a combination of proprietary quantitative and
qualitative equity research. Quantitative screening seeks to identify a group
of high-quality companies with above-average growth characteristics relative to
industry peers. Equity research seeks to identify individual companies from
that group with a higher potential for long term earnings growth and capital
appreciation.

The manager buys companies that seem attractive based on a combination of cri-
teria, among others:

 . Superior historical earnings growth,

 . Prospects for above-average growth,

 . Attractive valuations,

 . Strong market positions,

 . Favorable new products, and

 . Superior management.

The Fund is broadly diversified by industry sector. The Fund normally invests
in 60 to 100 stocks, with at least 65% (usually higher) of its assets in small
and mid cap companies. The Fund normally has 5% or less of its assets in cash
and cash equivalents.

The Fund may purchase other types of securities, for example: American Deposi-
tory Receipts (ADRs), and certain derivatives (investments whose value is based
on indices or other securities).

In abnormal market conditions, the Fund may take temporary defensive measures--
such as holding unusually large amounts of cash and cash equivalents--that are
inconsistent with the Fund's primary investment strategy. In taking those mea-
sures, the Fund may not achieve its investment goal.

The graph shows how the fund's total return has varied from year to year, while
the table shows performance over time (along with a broad-based market index
for reference). This information may help provide an indication of the fund's
risks and potential rewards. All figures assume dividend reinvestment. Past
performance does not indicate future results. The performance figures below do
not reflect the deduction of fees and charges payable under the variable
contracts. Such fees and charges would cause the investment returns under the
contracts to be less than that shown below.

MAIN RISKS

Primary

Small /Mid Cap Stock Risk: The Fund's investment in smaller or mid-sized compa-
nies may be subject to more erratic price movements than investment in large
established companies.

Market Risk: The value of the securities in the Fund may go down in response to
overall stock or bond market movements. Markets tend to move in cycles, with
periods of rising prices and periods of falling prices. Stocks tend to go up
and down in value more than bonds. If the Fund's investments are concentrated
in certain sectors, the Fund's performance could be worse than the overall mar-
ket.

Manager Risk: The manager and its strategy may fail to produce the intended
results. The Fund could underperform its 39 peers or lose money if the manager's
investment strategy does not perform as expected.

Investment Category Risk: The returns of the Fund's specific equity investment
category may lag the returns of the overall stock market. For example, the
Fund's "growth" approach carries the risk that in certain markets "growth"
stocks will underperform "value" stocks. Also, the Fund's "small/mid cap"
approach carries the risk that in certain markets small/mid cap stocks will
underperform large cap stocks.

Concentration Risk: The Fund's investment in securities of a smaller number of
issuers could produce more volatile performance relative to funds that invest
in a larger number of issuers. The more concentrated a fund's holdings are, the
more likely it is a specific security's poor performance will hurt the fund
significantly.

Turnover Risk: In general, the greater the volume of buying and selling by a
fund (i.e., the higher its "turnover rate"), the greater the impact that bro-
kerage commissions and other transaction costs will have on the fund's perfor-
mance. Any turnover rate in excess of 100% is considered relatively high. The
Fund had a high turnover rate in 1999 because of a change in management and a
change in the Fund's investment strategy. These changes required a restructur-
ing of the Fund's investments. In future years, the Fund's turnover rate will
normally be less than 100%.

Small Cap Value Fund

GOAL AND STRATEGY

This is a small cap stock fund with a value emphasis that seeks long-term
growth in capital.

The Fund invests primarily in a diversified mix of the common stocks of small
U.S. companies that are believed to offer favorable prospects for increasing
dividends and capital appreciation.

The manager applies a combination of quantitative techniques and equity
research to identify the best values among small company stocks.

Stocks are evaluated based on multiple factors, including:

 . earnings-to-price ratios;

 . earnings estimate revisions;

 . relative price strength; and

 . share issuance/buyback.

The Fund is managed using risk control techniques to maintain risk, style, cap-
italization and industry characteristics similar to the Russell 2000(R) Value
Index. The Fund normally invests in 150 to 250 stocks, with at least 65% (usu-
ally higher) of its assets in small cap companies. The Fund normally has 5% or
less of its assets in cash and cash equivalents.

The Fund may purchase other types of securities, for example: American Deposi-
tory Receipts (ADRs), and certain derivatives (investments whose value is based
on indices or other securities).

In abnormal market conditions, the Fund may take temporary defensive measures--
such as holding unusually large amounts of cash and cash equivalents--that are
inconsistent with the Fund's primary investment strategy. In taking those mea-
sures, the Fund may not achieve its investment goal.

Small Cap Growth Fund

GOAL AND STRATEGY

This is a small cap stock fund with a growth emphasis that seeks long-term
growth in capital.

The Fund invests primarily in a diversified mix of the common stocks of small
U.S. companies that are believed to offerabove-average potential for growth in
revenues and earnings.

The manager selects stocks using proprietary equity research. Stocks are pur-
chased that are expected to have rapid earnings growth that is not yet widely
recognized by the investment community.

The manager looks for companies with:

 . demonstrated annual 20% earnings growth over 3 years and/or similar future
  growth expectations;

 . dominant market niche or poised to become market leaders; and

 . high quality senior management with coherent business strategies.

The Fund is highly diversified by sector and number of individual stocks. The
Fund's sector weightings are broadly diversified and managed relative to those
of the Russell 2000(R) Growth Index. The Fund normally invests in 150 to 220
stocks, with at least 65% (usually higher) of its assets in small cap compa-
nies. The Fund normally has 5% or less of its assets in cash and cash equiva-
lents.

The Fund may purchase other types of securities, for example: American Deposi-
tory Receipts (ADRs), and certain derivatives (investments whose value is based
on indices or other securities).

In abnormal market conditions, the Fund may take temporary defensive measures--
such as holding unusually large amounts of cash and cash equivalents--that are
inconsistent with the Fund's primary investment strategy. In taking those mea-
sures, the Fund may not achieve its investment goal.

MAIN RISKS

Primary

Small /Mid Cap Stock Risk: The Fund's investment in smaller or mid-sized compa-
nies may be subject to more erratic price movements than investment in large
established companies.

Market Risk: The value of the securities in the Fund may go down in response to
overall stock or bond market movements. Markets tend to move in cycles, with
periods of rising prices and periods of falling prices. Stocks tend to go up
and down in value more than bonds. If the Fund's investments are concentrated
in certain sectors, the Fund's performance could be worse than the overall mar-
ket.

Manager Risk: The manager and its strategy may fail to produce the intended
results.
The Fund could underperform its peers or lose money if the manager's investment
strategy does not perform as expected.

Investment Category Risk: The returns of the Fund's specific equity investment
category may lag the returns of the overall stock market. For example, the
Fund's "growth" approach carries the risk that in certain markets "growth"
stocks will underperform "value" stocks. Also, the Fund's "small cap" approach
carries the risk that in certain markets small cap stocks will underperform mid
cap and large cap stocks.

Turnover Risk: In general, the greater the volume of buying and selling by a
fund (i.e., the higher its "turnover rate"), the greater the impact that bro-
kerage commissions and other transaction costs will have on the fund's perfor-
mance. Any turnover rate in excess of 100% is considered relatively high. Nor-
mally, the Fund's turnover rate will be greater than 100%.

Secondary

Derivatives Risk: Certain derivative instruments (such as options, futures and
swaps) can produce disproportionate gains or losses. They are generally consid-
ered more risky than direct equity investments. Also, in a down market, deriva-
tives could become harder to value or sell at a fair price.

Global Equity Fund
GOAL AND STRATEGY

This is a global stock fund that seeks long-term growth in capital.

The Fund primarily invests in a diversified mix of common stocks of:

 . large established U.S. companies; and

 . large established foreign companies located in countries throughout the
  world, including developed, newly industrialized, and emerging countries.

The manager makes ongoing decisions about the mix between U.S. and foreign
stocks. The manager has a target mix of 40% in U.S. stocks and 60% in foreign
stocks, but actively manages the mix within (+/-) 20 percentage points of the
target mix.

The manager uses global economic and industry analysis to identify global eco-
nomic and industry themes. The manager looks for companies that will benefit
from:

 . global economic trends;

 . promising technologies or products; and

 . specific country opportunities resulting from changing geopolitical, currency
  or economic relationships.

The manager purchases stocks of companies that are:

 . in growth industries;

 . efficient producers; and

 . undervalued relative to long-term growth potential.

The Fund invests:

 . in at least 3 different countries (including the U.S.), but normally in more
  than 15 countries; and

 . no more than 10% of its assets in emerging markets stocks.

Although the Fund may employ foreign currency hedging techniques, the Fund nor-
mally maintains the currency exposure of the underlying equity investments.

The Fund normally invests in 90 to 120 stocks, with at least 65% (usually high-
er) of its assets in large cap companies. The Fund normally has 5% or less of
its assets in cash and cash equivalents.

The Fund may purchase other types of securities, for example: American Deposi-
tory Receipts (ADRs), Global Depository Receipts (GDRs), European Depository
Receipts (EDRs), and certain derivatives (investments whose value is based on
indices or other securities).

In abnormal market conditions, the Fund may take temporary defensive measures--
such as holding unusually large amounts of cash and cash equivalents or invest-
ing 100% of its assets in U.S. companies--that are inconsistent with the Fund's
primary investment strategy. In taking those measures, the Fund may not achieve
its investment goal.

MAIN RISKS

Primary

Foreign Risk: The Fund's foreign securities will pose special risks, due to
limited government regulation, lack of public information, economic, political
and social instability and foreign currency rate fluctuations. Factors such as
lack of liquidity, foreign ownership limits and restrictions on removing cur-
rency also pose special risks. All foreign securities have some degree of for-
eign risk. However, to the extent the Fund invests in emerging market coun-
tries, it will have a significantly higher degree of foreign risk than if it
invested exclusively in developed or newly-industrialized countries.
Market Risk: The value of the securities in the Fund may go down in response
to overall stock or bond market movements. Markets tend to move in cycles,
with periods of rising prices and periods of falling prices. Stocks tend to go
up and down in value more than bonds. If the Fund's investments are concen-
trated in certain sectors, the Fund's performance could be worse than the
overall market.

Market Allocation Risk: The allocation of the Fund's assets among domestic and
international equity regions may (1) reduce the Fund's holdings in a region
whose value then increases unexpectedly, or (2) increase the Fund's holdings
in a region just prior to its experiencing a loss of value.
Manager Risk: The manager and its strategy may fail to produce the intended
results. The Fund could underperform its peers or lose money if the manager's
investment strategy does not perform as expected.


Secondary

Derivatives Risk: Certain derivative instruments (such as options, futures and
swaps) can produce disproportionate gains or losses. They are generally con-
sidered more risky than direct equity investments. Also, in a down market,
derivatives could become harder to value or sell at a fair price.

Global Balanced Fund
(Formerly International Balanced Fund)

GOAL AND STRATEGY

This is a non-diversified global balanced stock and bond fund that seeks long-
term growth in income and capital.

The Fund invests primarily in a mix of:

 . U.S. and foreign common stocks of large companies within developed markets;
  and

 . U.S. and foreign investment grade bonds of issuers within developed markets
  with maturities generally greater than 12 months.

The manager makes ongoing decisions about the mix between stocks and bonds. The
manager has a target mix of 65% stocks and 35% bonds, but actively manages the
mix within (+/-) 10 percentage points of the target mix.

The Fund invests:

 . in at least 3 different countries, but normally invests in 10 to 20 coun-
  tries; and

 . no more than 10% of its assets in emerging market stocks and bonds.

The manager selects stocks and bonds using fundamental value analysis to iden-
tify fairly priced investments with long-term sustainable cash flows. The man-
ager determines fundamental value by focusing on:

 . current market prices relative to fundamental values;

 . broad-based indices for stocks, bonds, and markets; and

 . economic variables such as productivity, inflation and global competitive-
  ness.

The Fund is non-diversified, which means that it can take larger positions in a
smaller number of issuers. However, the Fund normally invests in 125 to 250
stocks within the stock portion. The Fund normally has 10% or less of its
assets in cash and cash equivalents.

The Fund may purchase other types of securities, for example: American Deposi-
tory Receipts (ADRs), Global Depository Receipts (GDRs), European Depository
Receipts (EDRs), high yield bonds, and certain derivatives (investments whose
value is based on indices or other securities).

The manager actively uses derivatives, such as futures and forwards, to manage
the Fund's average maturity relative to the Salomon Brothers World Government
Bond Index Unhedged and to implement foreign currency strategies. Currency man-
agement strategies are primarily used for hedging purposes and to protect
against anticipated changes in foreign currency exchange rates.

In abnormal market conditions, the Fund may take temporary defensive measures--
such as holding unusually large amounts of cash and cash equivalents--that are
inconsistent with the Fund's primary investment strategy. In taking those mea-
sures, the Fund may not achieve its investment goal.

MAIN RISKS

Primary

Foreign Risk: The Fund's foreign securities will pose special risks, due to
limited government regulation, lack of public information, economic, political
and social instability and foreign currency rate fluctuations. Factors such as
lack of liquidity, foreign ownership limits and restrictions on removing cur-
rency also pose special risks. All foreign securities have some degree of for-
eign risk. However, to the extent the Fund invests in emerging market coun-
tries, it will have a significantly higher degree of foreign risk than if it
invested exclusively in developed or newly-industrialized countries.

Non-Diversified Fund Risk: The Fund's larger position in foreign government
securities could produce more volatile performance relative to funds with
smaller positions. The less diversified a fund's holdings are, the more likely
it is that a specific security's poor performance will hurt the fund signifi-
cantly.

Market Risk: The value of the securities in the Fund may go down in response to
overall stock or bond market movements. Markets tend to move in cycles, with
periods of rising prices and periods of falling prices. Stocks tend to go up
and down in value more than bonds. If the Fund's investments are concentrated
in certain sectors, the Fund's performance could be worse than the overall mar-
ket.
Manager Risk: The manager and its strategy may fail to produce the intended
results. The Fund could underperform its peers or lose money if the manager's
investment strategy does not perform as expected.

Investment Category Risk: The returns of the Fund's specific equity investment
category may lag the returns of the overall stock market. For example, the
Fund's "value" approach carries the risk that in certain markets "value" stocks
will underperform "growth" stocks. Also, the Fund's "large/mid cap" approach
carries the risk that large/mid cap stocks will underperform small cap stocks.

Market Allocation Risk: The allocation of the Fund's assets between the major
asset classes (i.e., stocks and bonds) may (1) reduce the Fund's holdings in a
class whose value then increases unexpectedly, or (2) increase the Fund's hold-
ings in a class just prior to its experiencing a loss of value.

Interest Rate Risk: When interest rates rise, the Fund's bond yields will gen-
erally rise and the Fund's bond prices will generally fall. When interest rates
fall, the reverse will generally occur. The longer the average remaining matu-
rity of bonds held by the Fund, the more sensitive the Fund is to interest rate
risk. This Fund has more interest rate risk than a short-term bond fund, but
less interest rate risk than a long-term bond fund.
Credit Risk: An issuer of a bond held by the Fund may default on its obligation
to pay interest and repay principal. Also, the credit rating of a bond held by
the fund may be downgraded. In either case, the value of the bond held by the
Trust would fall. All bonds have some credit risk, but in general lower-rated
bonds have higher credit risk.

Turnover Risk. In general, the greater the volume of buying and selling by a
fund (i.e., the higher its "turnover rate"), the greater the impact that bro-
kerage commissions and other transaction costs will have on the fund's perfor-
mance. Any turnover rate in excess of 100% is considered relatively high. Nor-
mally, the Fund's turnover rate will be greater than 100%.

Secondary

Derivatives Risk: Certain derivative instruments (such as options, futures and
swaps) can produce disproportionate gains or losses. They are generally consid-
ered more risky than direct equity investments. Also, in a down market, deriva-
tives could become harder to value or sell at a fair price.

High Yield Bond Risk. Junk bonds, defined as bond securities rated below BBB-
/Baa3, may be subject to more volatile or erratic price movements due to
investor sentiment. In a down market, these high yield securities become harder
to value or to sell at a fair price.

International Equity Index Fund

GOAL AND STRATEGY

This is an international stock fund that seeks to track the performance of
broad-based equity indices of foreign companies in developed and emerging mar-
kets.

The Fund is managed relative to a target mix of 90% in the MSCI EAFE GDP Index
and 10% in the MSCI EMF Index. The EAFE GDP Index, known as the Europe Austral-
asia and Far East Index, includes foreign companies in developed markets, with
country index weights based upon a country's Gross Domestic Product (GDP). The
EMF Index, known as the Emerging Markets Free Index, includes foreign companies
in emerging markets, with country index weights based upon a country's market
capitalization.

The manager employs a passive management strategy using quantitative techniques
to invest in a representative sample of stocks in the Index. The manager
selects stocks in an attempt to track, as closely as possible, the characteris-
tics of the Index, including country and sector weights. The Fund normally
invests in 400 to 1,200 stocks.

The Index composition changes from time to time. The manager will reflect those
changes as soon as practical.

The Fund is normally fully invested. The manager may invest in stock index
futures to maintain market exposure and manage cash flow. Although the Fund may
employ foreign currency hedging techniques, the Fund normally maintains the
currency exposure of the underlying equity investments.


The Fund may purchase other types of securities, for example: American Deposi-
tory Receipts (ADRs), Global Depository Receipts (GDRs), European Depository
Receipts (EDRs), cash equivalents, and certain derivatives (investments whose
value is based on indices or other securities).

Note: "MSCI EAFE GDP Index" and "MSCI EMF Index" are the exclusive property of
Morgan Stanley & Co., Incorporated and are registered service marks of Morgan
Stanley Capital International.

PAST PERFORMANCE

The graph shows how the fund's total return has varied from year to year, while
the table shows performance over time (along with a broad-based market index
for reference). This information may help provide an indication of the fund's
risks and potential rewards. All figures assume dividend reinvestment. Past
performance does not indicate future results. The performance figures below do
not reflect the deduction of fees and charges payable under the variable
contracts. Such fees and charges would cause the investment returns under the
contracts to be less than that shown below.

MAIN RISKS
Primary
Foreign Risk: The Fund's foreign securities will pose special risks, due to
limited government regulation, lack of public information, economic, political
and social instability and foreign currency rate fluctuations. Factors such as
lack of liquidity, foreign ownership limits and restrictions on removing cur-
rency also pose special risks. All foreign securities have some degree of for-
eign risk. However, to the extent the Fund invests in emerging market coun-
tries, it will have a significantly higher degree of foreign risk than if it
invested exclusively in developed or newly-industrialized countries.


Index Management Risk: Certain factors such as the following may cause the
Fund to track the Index less closely:


 . The securities selected by the manager may not be fully representative of
  the Index.

 . Transaction expenses of the Fund may result in the Fund's performance being
  different than that of the Index.
 . The size and timing of the Fund's cash flows may result in the Fund's per-
  formance being different than that of the Index.


Also, index funds like this one will have more difficulty in taking defensive
positions in abnormal market conditions.


Market Risk: The value of the securities in the Fund may go down in response
to overall stock or bond market movements. Markets tend to move in cycles,
with periods of rising prices and periods of falling prices.

Stocks tend to go up and down in value more than bonds. If the Fund's invest-
ments are concentrated in certain sectors, the Fund's performance could be
worse than the overall market.


Manager Risk: The manager and its strategy may fail to produce the intended
results. The Fund could underperform its peers or lose money if the manager's
investment strategy does not perform as expected.


Secondary
Derivatives Risk:  Certain derivative instruments (such as options, futures
and swaps) can produce disproportionate gains or losses. They are generally
considered more risky than direct equity investments. Also, in a down market,
derivatives could become harder to value or sell at a fair price.

International Equity Fund
GOAL AND STRATEGY

This is an international stock fund that seeks long-term growth in capital.

The Fund primarily invests in a diversified mix of common stocks of large
established and medium-sized foreign companies located primarily in developed
countries outside of the U.S.

The manager selects stocks using proprietary equity research that identifies
companies having:

 . strong market positions within their industry,

 . management with a history of excellence focusing on core businesses,

 . above average return on capital within their industry, and

 . demonstrated ability to create long-term shareholder value.

The manager determines the allocation among regions and countries using a com-
bination of qualitative and quantitative inputs, including:

 . quantitative models to rank the relative attractiveness of each
  country/region based on valuation, credit risk and momentum, and

 . qualitative assessment of regional portfolio managers to adjust model
  results.

The Fund's industry exposures are largely the result of stock selection,
although the Fund maintains broad industry representation. The Fund is managed
using risk control techniques that maintain overall regional diversification.
The Fund may either (i) employ foreign currency hedging techniques in order to
maintain a neutral currency position to the benchmark or (ii) maintain the cur-
rency exposure of the underlying equity investments.

The Fund invests in at least 3 different countries, but normally invests in 10
to 20 countries.

The Fund will invest no more than 10% of its assets in emerging market stocks.

The Fund normally invests in 120 to 180 stocks and normally has 10% or less of
its assets in cash and cash equivalents.

The Fund also may purchase other types of securities, for example: American
Depository Receipts (ADRs), Global Depository Receipts (GDRs), European Deposi-
tory Receipts (EDRs), and certain derivatives (investments whose value is based
on indices or other securities).

In abnormal market conditions, the Fund may take temporary defensive measures--
such as holding unusually large amounts of cash and cash equivalents--that are
inconsistent with the Fund's primary investment strategy. In taking those mea-
sures, the Fund may not achieve its investment goal.

International Opportunities Fund

GOAL AND STRATEGY

This is an international stock fund that seeks long-term growth in capital.

The Fund primarily invests in a diversified mix of common stocks of large
established and medium-sized foreign companies located throughout the world,
including developed, newly industrialized, and emerging countries.

The manager determines the distribution among countries and regions by using a
combination of fundamental research and economic analysis, emphasizing:

 . prospects for relative economic growth between foreign countries;

 . expected levels of inflation;

 . government policies influencing business conditions; and

 . outlook for currency relationships.
The manager selects stocks that have growth characteristics such as:

 . leading market position or technological leadership;

 . high return on invested capital;

 . healthy balance sheets with relatively low debt;

 . strong competitive advantage;

 . strength of management; and

 . earnings growth and cash flow sufficient to support growing dividends.

The Fund invests:

 . in at least 3 different countries; and

 . no more than 20% of its assets in emerging market stocks.

Although the Fund may employ foreign currency hedging techniques, the Fund nor-
mally maintains the currency exposure of the underlying equity investments.
The Fund normally invests in 200 to 300 stocks in 15 to 20 countries. The Fund
normally has 10% or less of its assets in cash and cash equivalents.

The Fund also may purchase other types of securities, for example: American
Depository Receipts (ADRs), Global Depository Receipts (GDRs), European Deposi-
tory Receipts (EDRs), and certain derivatives (investments whose value is based
on indices or other securities).

In abnormal market conditions, the Fund may take temporary defensive measures--
such as holding unusually large amounts of cash and cash equivalents--that are
inconsistent with the Fund's primary investment strategy. In taking those mea-
sures, the Fund may not achieve its investment goal.

The graph shows how the fund's total return has varied from year to year, while
the table shows performance over time (along with a broad-based market index
for reference). This information may help provide an indication of the fund's
risks and potential rewards. All figures assume dividend reinvestment. Past
performance does not indicate future results. The performance figures below do
not reflect the deduction of fees and charges payable under the variable
contracts. Such fees and charges would cause the investment returns under the
contracts to be less than that shown below.

MAIN RISKS

Primary

Foreign Risk: The Fund's foreign securities will pose special risks, due to
limited government regulation, lack of public information, economic, political
and social instability and foreign currency rate fluctuations. Factors such as
lack of liquidity, foreign ownership limits and restrictions on removing cur-
rency also pose special risks. All foreign securities have some degree of for-
eign risk. However, to the extent the Fund invests in emerging market coun-
tries,
it will have a significantly higher degree of foreign risk than if it invested
exclusively in developed or newly-industrialized countries.

Market Risk: The value of the securities in the Fund may go down in response
to overall stock or bond market movements. Markets tend to move in cycles,
with periods of rising prices and periods of falling prices. Stocks tend to go
up and down in value more than bonds. If the Fund's investments are concen-
trated in certain sectors, the Fund's performance could be worse than the
overall market.
Manager Risk: The manager and its strategy may fail to produce the intended
results. The Fund could underperform its peers or lose money if the manager's
investment strategy does not perform as expected.

Secondary

Derivatives Risk: Certain derivative instruments (such as options, futures and
swaps) can produce disproportionate gains or losses. They are generally con-
sidered more risky than direct equity investments. Also, in a down market,
derivatives could become harder to value or sell at a fair price.

Emerging Markets Equity Fund

GOAL AND STRATEGY

This is an emerging markets stock fund that seeks long-term growth in capital.

The Fund invests primarily in the stocks of companies in countries having econ-
omies or markets generally considered by the World Bank or United Nations to be
emerging or developing.

In making country allocation decisions, the manager analyzes the global envi-
ronment and selects countries with:

 . Improving macroeconomic, political and social trends, and

 . attractive valuation levels.

The manager selects stocks using fundamental proprietary research to identify
companies:

 . having strong earnings growth potential,

 . selling below their intrinsic value, and

 . having shareholder-focused management, dominant products, and well estab-
  lished distribution channels.

The Fund normally invests:

 . in at least 15 emerging market countries, and

 . no more than 30% of its assets in any single country.

The Fund normally invests in 100 to 250 stocks in 20 to 25 countries. The Fund
normally has 10% or less of its assets in cash and cash equivalents.

Although the Fund may employ foreign currency hedging techniques, the Fund
normally maintains the currency exposure of the underlying equity investments.

The Fund may purchase other types of securities, for example: American Deposi-
tory Receipts (ADRs), Global Depository Receipts (GDRs), European Depository
Receipts (EDRs), and certain derivatives (investments whose value is based on
indices or other securities).

In abnormal market conditions, the Fund may take temporary defensive measures--
such as holding unusually large amounts of cash and cash equivalents--that are
inconsistent with the Fund's primary investment strategy. In taking those mea-
sures, the Fund may not achieve its investment goal.

lack of liquidity, foreign ownership limits and restrictions on removing cur-

and down in value more than bonds. If the Fund's investments are concentrated
in certain sectors, the Fund's performance could be worse than the overall mar-
ket.

Manager Risk: The manager and its strategy may fail to produce the intended
results. The Fund could underperform its peers or lose money if the manager's
investment strategy does not perform as expected.

Turnover Risk: In general, the greater the volume of buying and selling by a
fund (i.e., the higher its "turnover rate"), the greater the impact that bro-
kerage commissions and other transaction costs will have on the funds perfor-
mance. Any turnover rate in excess of 100% is considered relatively high. The
Fund's turnover rate could be greater than 100% due to the relatively high vol-
atility associated with investing in emerging markets.

Secondary

Derivatives Risk: Certain derivative instruments (such as options, futures and
swaps) can produce disproportionate gains or losses. They are generally consid-
ered more risky than direct equity investments. Also, in a down market, deriva-
tives could become harder to value or sell at a fair price.

Short-Term Bond Fund

GOAL AND STRATEGY

This is a short-term bond fund that seeks high income consistent with low share
price fluctuation.

The Fund primarily invests in a diversified mix of short-term and intermediate-
term investment grade debt securities including:

 . U.S. Treasury and Agency securities;

 . U.S. corporate bonds;

 . foreign corporate bonds of companies in developed countries (if dollar-
  denominated);

 . foreign government and agency securities of developed countries (if dollar
  denominated); and

 . mortgage-and asset-backed securities.

The manager selects bonds using a combination of proprietary research and quan-
titative tools. Bonds are purchased that are attractively priced and that pro-
vide cheap, predictable cash flows.

The Fund normally invests:

 . mostly in corporate bonds;

 . no more than 15% of its assets in high yield bonds; and

 . no more than 25% of its assets in foreign debt securities.

The Fund normally has:

 . an average maturity between one and three and a half years;

 . an average credit quality rating of "A" or higher; and

 . 10% or less of its assets in cash and cash equivalents.

The Fund only invests in securities that are rated at least BB- or Ba3 at time
of purchase.

The Fund may purchase other types of securities, for example: certain deriva-
tives (investments whose value is based on indexes or other securities).

In abnormal market conditions, the Fund may take temporary defensive measures--
such as holding unusually large amounts of cash and cash equivalents--that are
inconsistent with the Fund's primary investment strategy. In taking those mea-
sures, the Fund may not achieve its investment goal.

MAIN RISKS

Primary

Market Risk: The value of the securities in the Fund may go down in response
to overall stock or bond market movements. Markets tend to move in cycles,
with periods of rising prices and periods of falling prices. Stocks tend to go
up and down in value more than bonds. If the Fund's investments are concen-
trated in certain sectors, the Fund's performance could be worse than the
overall market.

Manager Risk: The manager and its strategy may fail to produce the intended
results. The Fund could underperform its peers or lose money if the manager's
investment strategy does not perform as expected.

Interest Rate Risk: When interest rates rise, the Fund's bond yields will gen-
erally rise and the Fund's bond prices will generally fall. When interest
rates fall, the reverse will generally occur. The longer the average remaining
maturity of bonds held by the Fund, the more sensitive the Fund is to interest
rate risk. This Fund has less interest rate risk than an intermediate-term or
long-term bond fund.
Credit Risk: An issuer of a bond held by the Fund may default on its obliga-
tion to pay interest and repay principal. Also, the credit rating of a bond
held by the fund may be downgraded. In either case, the value of the bond held
by the Trust would fall. All bonds have some credit risk, but in general low-
er-rated bonds have higher credit risk.

Concentration Risk: The Fund's investment in securities of a smaller number of
issuers could produce more volatile performance relative to funds that invest
in a larger number of issuers. The more concentrated a fund's holdings are,
the more likely it is a specific security's poor performance will hurt the
fund significantly.

Turnover Risk: In general, the greater the volume of buying and selling by a
fund (i.e., the higher its "turnover rate"), the greater the impact that bro-
kerage commissions and other transaction costs will have on the fund's perfor-
mance. Any turnover rate in excess of 100% is considered relatively high. Nor-
mally, the Fund's turnover rate will be greater than 100%.
Secondary

Foreign Risk: The Fund's foreign securities will pose special risks, due to
limited government regulation, lack of public information, and economic,
political and social instability. Factors such as lack of liquidity, foreign
ownership limits and restrictions on removing currency also pose special
risks.

Derivatives Risk: Certain derivative instruments (such as options, futures and
swaps) can produce disproportionate gains or losses. They are generally con-
sidered more risky than direct equity investments. Also, in a down market,
derivatives could become harder to value or sell at a fair price.

High Yield Bond Risk: Junk bonds, defined as bond securities rated below BBB-
/Baa3, may be subject to more volatile or erratic price movements due to
investor sentiment. In a down market, these high yield securities become
harder to value or to sell at a fair price.

Prepayment / Call Risk: The Fund's share price or yield could be hurt if
interest rate movements cause the Fund's mortgage-related and callable securi-
ties to be paid off substantially earlier than expected.

Bond Index Fund

GOAL AND STRATEGY

This is a bond fund that seeks to track the performance of the Lehman Brothers
Government / Corporate Bond Index.

The manager employs a passive management strategy using quantitative techniques
to select individual securities that provide a representative sample of the
securities in the Index.

If the Fund reaches approximately $50 million in total assets, the manager will
seek to match the performance of the Lehman Brothers Aggregate Bond Index, a
broader market index that also includes mortgage-backed and asset-backed secu-
rities.

Both of these Indexes consist of dollar-denominated investment grade securities
with maturities greater than one year and outstanding par values of at least
$150 million issued primarily by:

 . the U.S. Treasury and U.S. government agencies and instrumentalities;

 . foreign governments and agencies; and

 . U.S. and foreign corporations.

The manager selects securities to match, as closely as practical, the Index's
duration, cash flow, sector, credit quality, callability, and other key perfor-
mance characteristics. The Fund may hold some cash and cash equivalents, but is
normally fully invested.
The Index composition may change from time to time. The manager may keep secu-
rities that no longer meet the Index criteria as long as:

 . such "ineligible" securities plus cash and money market instruments are less
  than 20% of the Fund's assets; and

 . high yield securities are less than 5% of the Fund's assets.

MAIN RISKS

Primary

Index Management Risk:  Certain factors such as the following may cause the
Fund to track the Index less closely:

 . The securities selected by the manager may not be fully representative of the
  Index.

 . Transaction expenses of the Fund may result in the Fund's performance being
  different than that of the Index.

 . The size and timing of the Fund's cash flows may result in the Fund's perfor-
  mance being different than that of the Index.

Also, index funds like this one will have more difficulty in taking defensive
positions in abnormal market conditions.

Market Risk: The value of the securities in the Fund may go down in response to
overall stock or bond market movements. Markets tend to move in cycles, with
periods of rising prices and periods of falling prices. Stocks tend to go up
and down in value more than bonds. If the Fund's investments are concentrated
in certain sectors, the Fund's performance could be worse than the overall mar-
ket.

Manager Risk: The manager and its strategy may fail to produce the intended
results. The Fund could underperform its peers or lose money if the manager's
investment strategy does not perform as expected.

Interest Rate Risk: When interest rates rise, the Fund's bond yields will gen-
erally rise and the Fund's bond prices will generally fall. When interest rates
fall, the reverse will generally occur. The longer the average remaining matu-
rity of bonds held by the Fund, the more sensitive the Fund is to interest rate
risk. This Fund has more interest rate risk than a short-term bond fund, but
less interest rate risk than a long-term bond fund.

Credit Risk: An issuer of a bond held by the Fund may default on its obligation
to pay interest and repay principal. Also, the credit rating of a bond held by
the fund may be downgraded. In either case, the value of the bond held by the
Trust would fall. All bonds have some credit risk, but in general lower-rated
bonds have higher credit risk.

Secondary

Foreign Risk: The Fund's foreign securities will pose special risks, due to
limited government regulation, lack of public information, and economic, polit-
ical and social instability. Factors such as lack of liquidity, foreign owner-
ship limits and restrictions on removing currency also pose special risks. All
foreign securities have some degree of foreign risk. However, to the extent the
Fund invests in emerging market countries, it will have a significantly higher
degree of foreign risk than if it invested exclusively in developed or newly-
industrialized countries.

Active Bond Fund
(Formerly Sovereign Bond Fund)

GOAL AND STRATEGY

This is a bond fund that seeks income and growth in capital.

The Fund primarily invests in a diversified mix of debt securities including:

 . U.S. Treasury and agency securities;

 . foreign government and agency securities (if dollar-denominated);

 . corporate bonds, both U.S. and foreign (if dollar-denominated); and

 . mortgage-backed and asset-backed securities.

The manager normally invests:

 . mostly in investment grade debt securities;

 . no more than 25% of the Fund's assets in high yield bonds; and

 . no more than 25% of the Fund's assets in foreign securities, excluding Cana-
  dian securities.

The manager seeks to identify specific bond sectors, industries and specific
bonds that are attractively priced. The manager tries to anticipate shifts in
the business cycle, using economic and industry analysis to determine which
sectors and industries might benefit over the next 12 months. The manager uses
proprietary research to identify securities that are undervalued.

The manager evaluates bonds of all quality levels and maturities from many dif-
ferent issuers. The Fund normally has an average credit rating A or higher.

The Fund normally has 10% or less of its assets in cash and cash equivalents.
The Fund may purchase other types of securities, for example: emerging market
debt securities, and certain derivatives (investments whose value is based on
indices or other securities). The manager actively uses derivatives, such as
futures, to adjust the Fund's average maturity relative to the
Lehman Brothers Aggregate Bond Index and seeks to keep the Fund's interest rate
sensitivity in line with the overall market.

In abnormal market conditions, the Fund may take temporary defensive measures--
such as holding unusually large amounts of cash and cash equivalents--that are
inconsistent with the Fund's primary investment strategy. In taking those mea-
sures, the Fund may not achieve its investment goal.

MAIN RISKS

Primary

Market Risk: The value of the securities in the Fund may go down in response
to overall stock or bond market movements. Markets tend to move in cycles,
with periods of rising prices and periods of falling prices. Stocks tend to go
up and down in value more than bonds. If the Fund's investments are concen-
trated in certain sectors, the Fund's performance could be worse than the
overall market.

Manager Risk: The manager and its strategy may fail to produce the intended
results. The Fund could underperform its peers or lose money if the manager's
investment strategy does not perform as expected.

Interest Rate Risk: When interest rates rise, the Fund's bond yields will gen-
erally rise and the Fund's bond prices will generally fall. When interest
rates fall, the reverse will generally occur. The longer the average remaining
maturity of bonds held by the Fund, the more sensitive the Fund is to interest
rate risk. This Fund has more interest rate risk than a short-term bond fund,
but less interest rate risk than a long-term bond fund.

Credit Risk: An issuer of a bond held by the Fund may default on its obliga-
tion to pay interest and repay principal. Also, the credit rating of a bond
held by the fund may be downgraded. In either case, the value of the bond held
by the Fund would fall. All bonds have some credit risk, but in general lower-
rated bonds have higher credit risk.
Turnover Risk: In general, the greater the volume of buying and selling by a
fund (i.e., the higher its "turnover rate"), the greater the impact that bro-
kerage commissions and other transaction costs will have on the fund's perfor-
mance. Any turnover rate in excess of 100% is considered relatively high. Nor-
mally, the Fund's turnover rate will be greater than 100%.

Secondary

Foreign Risk: The Fund's foreign securities will pose special risks, due to
limited government regulation, lack of public information, and economic,
political and social instability. Factors such as lack of liquidity, foreign
ownership limits and restrictions on removing currency also pose special
risks. All foreign securities have some degree of foreign risk. However, to
the extent the Fund invests in emerging market countries, it will have a sig-
nificantly higher degree of foreign risk than if it invested exclusively in
developed or newly-industrialized countries.

Derivatives Risk: Certain derivative instruments (such as options, futures and
swaps) can produce disproportionate gains or losses. They are generally con-
sidered more risky than direct equity investments. Also, in a down market,
derivatives could become harder to value or sell at a fair price.

High Yield Bond Risk: Junk bonds, defined as bond securities rated below BBB-
/Baa3, may be subject to more volatile or erratic price movements due to
investor sentiment. In a down market, these high yield securities become
harder to value or to sell at a fair price.

Prepayment/Call Risk: The Fund's share price or yield could be hurt if inter-
est rate movements cause the Fund's mortgage-related and callable securities
to be paid off substantially earlier than expected.

Global Bond Fund

GOAL AND STRATEGY

This is a global bond fund that seeks income and growth in capital.

The Fund primarily invests in a mix of debt securities of developed countries
throughout the world including:

 . U.S. Treasury and agency securities;

 . foreign government and agency securities;

 . supranational securities (such as the World Bank);

 . corporate bonds, both U.S. and foreign; and

 . mortgage-backed and asset-backed securities.

The manager makes ongoing decisions regarding the Fund's mix of U.S. bonds and
non-U.S. bonds (denominated in foreign currencies). The manager has a target
mix of 35% U.S. bonds and 65% non-U.S. bonds, but actively manages the mix
within (+/-) 50 percentage points of the target mix.

The Fund invests in at least 3 countries, but normally in 5 to 15 countries.
The Fund normally has an average credit quality rating of "AA" or higher.

The manager makes ongoing decisions regarding the Fund's average maturity,
country and sector allocations and foreign currency exposures. The manager uses
proprietary research and economic analysis to try to anticipate market condi-
tions and interest rate movements and to purchase securities that appear com-
paratively undervalued.

The manager actively uses derivatives (investments whose value is based on
indices or other securities) such as futures, forwards, options and swaps to
adjust the Fund's average maturity and to implement currency strategies. The
Fund is typically 75% to 100% hedged to the U.S. dollar.

The manager actively uses cash and cash equivalents to manage the Fund's aver-
age maturity. However, the Fund normally invests 20% or less of its assets in
cash and cash equivalents.

The Fund may purchase other types of securities, for example: high yield debt
securities and emerging market debt securities.

In abnormal market conditions, the Fund may take temporary defensive measures--
such as holding unusually large amounts of cash and cash equivalents--that are
inconsistent with the Fund's primary investment strategy. In taking those mea-
sures, the Fund may not achieve its investment goal.

MAIN RISKS

Primary

Foreign Risk: The Fund's foreign securities will pose special risks, due to
limited government regulation, lack of public information, economic, political
and social instability and foreign currency rate fluctuations. Factors such as
lack of liquidity, foreign ownership limits and restrictions on removing cur-
rency also pose special risks. All foreign securities have some degree of for-
eign risk. However, the Fund's investments in emerging market countries have a
significantly higher degree of foreign risk than investments in developed or
newly-industrialized countries.

Market Risk: The value of the securities in the Fund may go down in response to
overall stock or bond market movements. Markets tend to move in cycles, with
periods of rising prices and periods of falling prices. Stocks tend to go up
and down in value more than bonds. If the Fund's investments are concentrated
in certain sectors, the Fund's performance could be worse than the overall mar-
ket.

Manager Risk: The manager and its strategy may fail to produce the intended
results. The Fund could underperform its peers or lose money if the manager's
investment strategy does not perform as expected.

Interest Rate Risk: When interest rates rise, the Fund's bond yields will gen-
erally rise and the Fund's bond prices will generally fall. When interest rates
fall, the reverse will generally occur. The longer the average remaining matu-
rity of bonds held by the Fund, the more sensitive the Fund is to interest rate
risk. This Fund has more interest rate risk than a short-term bond fund, but
less interest rate risk than a long-term bond fund.

Credit Risk: An issuer of a bond held by the Fund may default on its obligation
to pay interest and repay principal. Also, the credit rating of a bond held by
the fund may be downgraded. In either case, the value of the bond held by the
Trust would fall. All bonds have some credit risk, but in general lower-rated
bonds have higher credit risk.

Concentration Risk: The Fund's investment in securities of a smaller number of
issuers could produce more volatile performance relative to funds that invest
in a larger number of issuers. The more concentrated a fund's holdings are, the
more likely it is a specific securities poor performance will hurt the fund
significantly.

Turnover Risk: In general, the greater the volume of buying and selling by a
fund (i.e., the higher its "turnover rate"), the greater the impact that bro-
kerage commissions and other transaction costs will have on the fund's perfor-
mance. Any turnover rate in excess of 100% is considered relatively high. Nor-
mally, the Fund's turnover rate will be greater than 100%.

Derivatives Risk: Certain derivative instruments (such as options, futures and
swaps) can produce disproportionate gains or losses. They are generally consid-
ered more risky than direct equity investments. Also, in a down market, deriva-
tives could become harder to value or sell at a fair price.

High Yield Bond Fund

GOAL AND STRATEGY

This is a high yield bond fund that seeks high income and growth in capital.

The Fund invests primarily in a diversified mix of high yield debt securities,
commonly referred to as "junk bonds" (rated BB+/Ba1 or lower and their unrated
equivalents), including:

 . corporate bonds, both U.S. and foreign (if dollar-denominated);

 . foreign government and agency securities (if dollar-denominated);

 . preferred stocks; and

 . convertible securities (convertible into common stocks or other equity inter-
  ests).

The manager will invest no more than 15% of the Fund's assets in emerging mar-
ket countries (with below investment-grade sovereign debt). The Fund normally
has 10% or less of its assets in cash and cash equivalents.

The manager seeks to purchase bonds with stable or improving credit quality
before the market widely perceives the improvement. Purchase and sale decisions
are primarily based upon the investment merits of the particular security.

The manager selects bonds using proprietary research, including:

 . quantitative analysis of historical financial data;

 . qualitative analysis of a company's future prospects; and

 . economic and industry analysis.

The Fund's average maturity depends on security selection decisions rather than
interest rate decisions.

The Fund may purchase other types of securities, for example: equity securi-
ties, high quality debt securities (short-term and otherwise), certain deriva-
tives (investments whose value is based on indices or other securities), and
debt securities denominated in foreign currencies.

In abnormal market conditions, the Fund may take temporary defensive measures--
such as holding unusually large amounts of cash and cash equivalents--that are
inconsistent with the Fund's primary investment strategy. In taking those mea-
sures, the Fund may not achieve its investment goal.

PAST PERFORMANCE

The graph will show how the fund's total return varies from year to year, while
the table will show performance over time (along with a broad-based market
index for reference). This information may help provide an indication of the
fund's risks and potential rewards. All figures assume dividend reinvestment.
Past performance does not indicate future results. The performance figures
below do not reflect the deduction of fees and charges payable under the
variable contracts. Such fees and charges would cause the investment returns
under the contracts to be less than that shown below.

MAIN RISKS

Primary

High Yield Bond Risk: High yield or junk bonds, defined as bond securities
rated below BBB-/Baa3, may be subject to more volatile or erratic price move-
ments due to investor sentiment. In a down market, these high yield securities
may become harder to value or to sell at a fair price.

Market Risk: The value of the securities in the Fund may go down in response to
overall stock or bond market movements. Markets tend to move in cycles, with
periods of rising prices and periods of falling prices. Stocks tend to go up
and down in value more than bonds. If the Fund's investments are concentrated
in certain sectors, the Fund's performance could be worse than the overall mar-
ket.

Manager Risk: The manager and its strategy may fail to produce the intended
results. The Fund could underperform its peers or lose money if the manager's
investment strategy does not perform as expected.
Interest Rate Risk: When interest rates rise, the Fund's bond yields will gen-
erally rise and the Fund's bond prices will generally fall. When interest rates
fall, the reverse will generally occur. The longer the average remaining matu-
rity of bonds held by the Fund, the more sensitive the Fund is to interest rate
risk. This Fund has more interest rate risk than a short-term bond fund, but
less interest rate risk than a long-term bond fund.

Credit Risk: An issuer of a bond held by the Fund may default on its obligation
to pay interest and repay principal. Also, the credit rating of a bond held by
the fund may be downgraded. In either case, the value of the bond held by the
Fund would fall. All bonds have some credit risk, but in general lower-rated
bonds have higher credit risk.

Secondary

Foreign Risk: The Fund's foreign securities will pose special risks, due to
limited government regulation, lack of public information, and economic, polit-
ical and social instability. Factors such as lack of liquidity, foreign owner-
ship limits and restrictions on removing currency also pose special risks. All
foreign securities have some degree of foreign risk. However, to the extent the
Fund invests in emerging market countries, it will have a significantly higher
degree of foreign risk than if it invested exclusively in developed or newly-
industrialized countries.

Derivatives Risk: Certain derivative instruments (such as options, futures and
swaps) can produce disproportionate gains or losses. They are generally consid-
ered more risky than direct equity investments. Also, in a down market, deriva-
tives could become harder to value or sell at a fair price.

Prepayment/Call Risk: The Fund's share price or yield could be hurt if interest
rate movements cause the Fund's mortgage-related and callable securities to be
paid off substantially earlier than expected.

Money Market Fund

GOAL AND STRATEGY

This is a money market fund that seeks current income consistent with maintain-
ing liquidity and preserving capital. The Fund intends to maintain a stable net
asset value of $10 per share.

The Fund only invests in U.S. dollar denominated money market instruments rated
within the two highest short-term credit rating categories, primarily includ-
ing:

 . commercial paper;

 . asset-backed commercial paper;

 . bank notes and certificates of deposit;

 . short-term bonds;

 . U.S. Treasury and agency notes and bills; and

 . repurchase and reverse repurchase agreements.

These securities have a maximum remaining maturity of 397 days (13 months) and
may be issued by:

 . U.S. and foreign banks and other lending institutions;

 . U.S. and foreign corporations;

 . the U.S. Treasury and U.S. government agencies and instrumentalities;

 . entities whose obligations are guaranteed as to principal or interest by the
  U.S. Government;

 . municipalities;

 . foreign governments; and

 . supranational organizations (such as the World Bank).

The weighted average time to maturity of the Fund's investments is 90 days or
less.

The manager may invest:

 . up to 5% of assets in securities rated in the second-highest short-term cate-
  gory (or unrated equivalents); and

 . up to 1% of assets or $1 million (whichever is greater) in securities of a
  single issuer rated in the second-highest short-term category (or unrated
  equivalents).

The manager selects securities with the highest yield available among securi-
ties of comparable credit quality and maturity using proprietary research.

MAIN RISKS

Primary

Manager Risk: The manager and its strategy may fail to produce the intended
results. The Fund could underperform its peers or lose money if the manager's
investment strategy does not perform as expected.

Interest Rate Risk: When interest rates rise, yields on the Fund's investments
will generally rise and prices on the Fund's investments will generally fall.
When interest rates fall, the reverse will generally occur. The longer the
average remaining maturity of instruments held by the Fund, the more sensitive
the Fund is to interest rate risk. This Fund has less interest rate risk than
an intermediate-term or long-term bond fund.

Credit Risk: An issuer of an instrument held by the Fund may default on its
obligation to pay interest and repay principal. Also, the credit rating of an
instrument held by the Fund may be downgraded. In either case, the value of the
instrument held by the Fund would fall. All money market instruments have some

Your Account

Investments in shares of the funds

Each fund sells its shares directly to separate accounts of John Hancock,
JHVLICO and IPL to fund variable contracts. Each fund also buys back its shares
on redemption by the separate accounts.

Under the variable contracts, a separate account buys or redeems a fund's
shares based on:

 . instructions by you and other contractowners to invest or receive back monies
  under a contract (such as making a premium payment or surrendering a con-
  tract), and

 . the operation of a contract (such as deduction of fees and charges).

The Trust, as law permits, may:

 . refuse a buy order if the adviser believes it would disrupt management

 . suspend a fund's offer of shares, or

 . suspend a fund's redemption obligation or postpone a fund's payment of
  redemption proceeds for more than seven days.

Share price

Each fund sells and buys back its shares at the net asset value per share
("NAV") next computed after receipt by a separate account of a contractowner's
instructions.

Each fund calculates its NAV:

 . by dividing its net assets by the number of its outstanding shares,

 . once daily as of the close of regular trading on the New York Stock Exchange
  (generally at 4 p.m. New York time) on each day the Exchange is open.

Certain funds may hold securities primarily listed on foreign exchanges that
trade on weekends or other days when the Trust does not calculate NAV. Conse-
quently, NAV may change on days when contractowners will not be able to
instruct a separate account to buy or redeem fund shares.

Valuation

The Money Market Fund values its securities at amortized cost. Each of the
other funds values securities based on:

 . market quotations,

 . amortized cost,

 . valuations of independent pricing services, or

 . fair value determined in accordance with procedures approved by the Trust's
  trustees.

A fund may value securities at fair value where, for example:

 .market quotations are not readily available, or

 . the value of securities has been materially affected after the closing of a
  foreign market.

Conflicts

The Trust's trustees monitor for possible material irreconcilable conflicts
among separate accounts buying shares of the funds. The Trust's net asset value
could decrease, if the Trust had to sell investment securities to pay redemp-
tion proceeds to a separate account withdrawing because of a conflict.

The adviser pays subadvisory fees out of its own assets. No fund pays a fee to
its subadviser.

The adviser has agreed to limit each fund's annual expenses (excluding advisory
fees and certain other expenses such as brokerage and taxes) to not more than
 .10 percent of the fund's average daily net assets.
Dividends and Taxes

Dividends

Each fund automatically reinvests its dividends and distributions in additional
shares of the fund at NAV.

Each fund declares and pays dividends monthly, except that the Money Market
Fund does so daily.

Funds generally declare capital gains distributions annually.

Taxes

Each fund must meet investment diversification and other requirements under the
Internal Revenue Code, in order to:

 . avoid federal income tax and excise tax, and

 . assure the tax-deferred treatment of variable contracts under the Code.

You should read the prospectus for your variable contract for the federal
income tax consequences for contractowners, including the consequences of a
fund's failure to meet Code requirements.

APPENDIX

Additional Performance Information

The "Past Performance" information shown earlier in this prospectus for certain
of the Funds may not be sufficient for you to make a complete assessment of the
risks and potential rewards of investing in those Funds. The Aggressive Bal-
anced Fund, the Large Cap Value Fund, the Large Cap Aggressive Growth Fund, the
Large/Mid Cap Value Fund, the Mid Cap Blend Fund, and the Small/Mid Cap Value
Fund only began operations on August 31, 1999. The Small/Mid Cap CORE Fund, the
Emerging Markets Equity Fund, the Bond Index Fund, and the High Yield Bond Fund
only began operations on May 1, 1998. The Small/Mid Cap Growth Fund and the
Global Bond Fund each implemented a significant change in strategy as of May 1,
1999. Finally, the Global Balanced Fund implemented a significant change in
strategy as of May 1, 2000.

Since each of these Funds has at best a very limited period of relevant perfor-
mance history, we have set forth below information for certain similar accounts
that are managed by the Funds' respective subadvisers. Each grouping of such
accounts is referred to as a "composite." In the case of each account included
in a composite, the total management fees and other operating expenses of the
Fund (based upon management fee schedules and allocation rules currently in
effect) have been substituted for the actual fees and expenses (other than bro-
kerage and other transaction expenses) of the account. Also, except as specifi-
cally noted below, each composite includes all of the investment company and
other accounts of the subadviser that satisfy the following requirements:

 . they have been managed with investment objectives, policies, and strategies
  substantially similar to those used in managing the Fund, and

 . they are of sufficient size that their performance would be considered rele-
  vant to the owner of a variable contract investing in that Fund.

Some of the accounts in the composites were not registered investment companies
and, therefore, were not subject to federal income tax and other legal require-
ments applicable to such companies. Had such accounts been subject to such
requirements, their performance could have been adversely affected. The perfor-
mance figures in this Appendix do not reflect the deduction of fees and charges
payable under the variable contracts. Such fees and charges would cause the
investment returns under the contacts to be less than that shown below.

The graphs below show how the composite's total return has varied from year to
year, while the tables show performance over time (along with a broad-based
index for reference). All figures assume dividend reinvestment. Past perfor-
mance does not indicate future results.

Aggresive Balanced Composite (Corresponding to Aggressive Balanced Fund)

The Aggressive Balanced Composite represents the following blend of two other
composites: 75% Diversified Core Equity Composite and 25% Active Core Bond Com-
posite. Each composite is asset-weighted and contains all fully discretionary
accounts managed using a substantially similar investment strategy. As of
December 31, 1999, the Diversified Core Equity Composite included 97 accounts
with total assets of $8.9 billion, and the Active Core Bond Composite included
9 accounts with total assets of $1.1 billion.

                               WHAT IS THE TRUST?

     John Hancock Variable Series Trust I, (the "Trust") is an open-end
management investment company. With the exception of the Large Cap Aggressive
Growth, Mid Cap Growth, Global Balanced and Global Bond Funds, each of the Funds
is a "diversified" Fund within the meaning of the Investment Company Act of 1940
(the "Investment Company Act").

     Shares of the Trust are currently sold to John Hancock Variable Life
Accounts U, V, and S to support variable life insurance policies issued by John
Hancock Variable Life Insurance Company ("JHVLICO"); John Hancock Variable
Annuity Accounts U and V to support variable annuity contracts issued by John
Hancock Life Insurance Company ("John Hancock"); John Hancock Variable Annuity
Account I to support variable annuity contracts issued by JHVLICO; John Hancock
Variable Life Insurance Account UV to support variable life insurance policies
issued by John Hancock; and Investors Partner Life Account IPL-1 to support
variable life insurance policies issued by Investors Partner Life Insurance
Company ("IPL"). It is anticipated that, in the future, Trust shares may be sold
to other separate investment accounts of JHVLICO, John Hancock and IPL. Each of
these separate accounts is hereinafter referred to as a "Separate Account."

     Because the Separate Accounts currently own all of the Trust's shares,
those Separate Accounts (or John Hancock, JHVLICO, and IPL) may be deemed to
control the Trust. John Hancock, JHVLICO and IPL, in turn, are all directly or
indirectly controlled by John Hancock Financial Services, Inc., a publicly-
traded holding company.

     The Trust issues a separate series of shares of beneficial interest for
each Fund.  Each share issued with respect to a Fund has a pro rata interest in
the net assets of that Fund.  The assets of each Fund are charged with the
liabilities of that Fund and a proportionate share of the general liabilities of
the Trust.

                          THE TRUST'S BUSINESS HISTORY

     The Trust is, in part, a successor to three Separate Accounts of JHVLICO,
as well as the six Separate Accounts of John Hancock described below. On March
28, 1986, all of the investment assets and related liabilities of the Variable
Life Stock, Bond, and Money Market Accounts were transferred to what are now the
Growth & Income, Active Bond and Money Market Funds of the Trust, respectively,
in exchange for shares of those Funds.

     On February 20, 1987, all of the investment assets and related liabilities
of six Variable Annuity Stock, Bond and Money Market Accounts were transferred
to what are now the Growth & Income, Active Bond and Money Market Funds of the
Trust, respectively, in exchange for shares of these Funds.

     The Trust itself was incorporated on September 23, 1985, under the laws of
the State of Maryland and was reorganized as a Massachusetts business trust
effective April 29, 1988.

     Over the years, several Funds have been re-named as follows:

                        THE FUNDS' INVESTMENT ACTIVITIES
                                 AND THEIR RISKS

     The different investment activities of the several Funds will affect both
their investment returns and the nature and degree of risks to which they are
exposed. Sections 1. - 29. below describe many (but not all) of these investment
activities and risks.

1.   Investing in Money Market Instruments

     The Money Market Fund invests exclusively in "money market" instruments;
all the other Funds may invest in these instruments to some extent. These are
high quality, short-term fixed income obligations. Because of their nature,
money market instruments generally do not carry significant risks of loss. The
principal risk is that a Fund's return on money market instruments will be less
than it would have earned on a riskier investment.

2.   Investing in Other Fixed Income Obligations

     The following Funds invested primarily in non-money market fixed income
(i.e., "debt") securities: the Short-Term Bond, Bond Index, Active Bond, Global
Bond, and High Yield Bond Funds. The Managed, Aggressive Balanced and Global
Balanced Funds can vary their holdings of these securities within a broad range.
All the other Funds (except the Money Market Fund)may from time to time invest
in non-money market debt to some extent.

     Various types of risk associated with these securities are discussed in the
balance of this Section 2.

     Interest rate risk: In general, debt securities with longer maturities than
money market instruments have exposure to interest rate risk. Changes in
generally prevailing market interest rates alter a debt security's market value
and introduce volatility into the rate of return of a Fund that invests in such
securities. When prevailing interest rates go up, the market value of debt
securities tends to go down and vice versa. This sensitivity of the market value
of a debt security to changes in interest rates is generally related to the
"duration" of the instrument. The market value of a shorter-term fixed income
security is generally less sensitive to interest rate moves than that of a
longer-term security. For example, the interest rate risk of the Short-Term Bond
Fund, although moderate, is below that of traditional intermediate or long- term
bond portfolios.

     Credit risk: The value of a fixed income security may also change as a
result of market perceptions regarding its credit risk: i.e., the ability of the
borrower to repay its debts. The market value of a fixed income security can
fall when the market perceives the borrower to be less credit worthy.
Conversely, the market value of a fixed income security can increase due to its
borrower being perceived as financially stronger. All Funds that invest in non-
money market debt securities may have some exposure to credit risk.

     Even some U.S. Government obligations have a degree of credit risk. "U.S.
Government obligations" are bills, certificates of indebtedness, notes and bonds
issued or guaranteed as to principal or interest by the United States or by
agencies or authorities controlled or supervised by and acting as
instrumentalities of the U.S. Government and established under the authority
granted by Congress. Some obligations of U.S. Government

                                       5
<PAGE>

agencies, authorities, and other instrumentalities are supported by the full
faith and credit of the U.S. Treasury; others by the right of the issuer to
borrow from the Treasury; and others only by the credit of the issuing agency,
authority, or other instrumentality. These latter types of obligations,
therefore, do have a degree of credit risk. U.S. Government obligations are used
most in the Bond Index, Active Bond and Global Bond Funds. All of the other
Funds may also invest in U.S. Government obligations to some extent.

     Securities having one of the four highest rating categories for debt
securities as defined by Moody's investors Services, Inc. (Aaa, Aa, A, or Baa)
or Standard and Poor's Corporation (AAA, AA, A, or BBB) or, if unrated,
determined to be of comparable quality by the subadviser, are referred to as
"investment grade." The meanings of such ratings are set forth in Appendix A to
this Statement of Additional Information. Lower-rated bonds have more credit
risk than higher rated bonds.

     Risk of lower-quality instruments: High-yield bonds (or "junk" bonds) are
debt securities rated below "investment grade" as defined above. The value of
these lower rated securities generally is more subject to credit risk than is
the case for higher rated securities, and their values tend to respond more to
changes in market perceptions regarding their credit risk.

     Investments in companies issuing high yield securities are considered to be
more speculative than higher quality instruments. As such, these securities
typically pay a higher interest rate than investment grade securities.

     Issuers of high yield securities are typically in weak financial health,
and their ability to pay back principal and interest on the bonds they issue is
uncertain. Some of these issuers may be in default or bankruptcy. Compared with
issuers of investment-grade bonds, they are more likely to encounter financial
difficulties and to be materially affected by these difficulties when they do
encounter them.

     High yield bond markets may react strongly to adverse news about an issuer
or the economy, or to the perception or expectations of adverse news. These debt
securities may also have less liquid markets than higher rated securities.

     Judgment plays a greater role in valuing higher yield securities than in
the case of other securities for which more extensive quotations and last-sale
information are available. Adverse publicity and changing investor perceptions
may affect the ability of outside pricing services used by a Fund to value its
portfolio securities, and the ability of the Fund to dispose of its lower-rated
bonds.

     The market prices of high yield securities may decline significantly in
periods of general economic difficulty, which may follow periods of rising
interest rates. During an economic downturn or a prolonged period of risking
interest rates, the ability of issuers of lower-rated debt to service their
payment obligations, meet projected goals, or obtain additional financing may be
impaired. In that case, a Fund may find it necessary, at its own expense or in
conjunction with others, to pursue litigation or otherwise exercise its rights
as a security holder to seek to protect the interests of security holders, if it
determines this to be in the interest of Fund investors. The 1980s saw a
dramatic increase in the use of high yield securities to finance highly
leveraged corporate acquisitions and restructurings. Past experience may not
provide an accurate indication of future performance of high yield securities,
especially during periods of economic recession. In fact, from 1989 to 1991, the
percentage of high yield securities that defaulted rose significantly above
prior levels.

     All Funds (other than the Money Market Fund) that invest in debt securities
may at times have some exposure to high yield securities. The High Yield Bond
Fund intends to invest primarily in these securities. The other Funds most
likely to invest a significant portion of their assets in high yield securities
are the Short-Term Bond, and Active Bond Funds. The Managed, Aggressive
Balanced, Global Bond and Global Balanced Funds may also invest in high yield
securities to some extent. In contrast, the Bond Index Fund will not invest in
debt securities that are not at least investment grade at the time of purchase.

     Although not customarily referred to as "high yield" securities or "junk
bonds," debt securities that fall in the lowest rating within the investment
grade category are considered medium grade securities that have some speculative
characteristics. Accordingly, to a lesser degree, they may present the same
risks discussed above with respect to high yield securities.

                                       6
<PAGE>

     The considerations discussed above for lower-rated debt securities also are
applicable to lower quality unrated debt instruments of all types, including
loans and other direct indebtedness of businesses with poor credit standing.
Unrated debt instruments are not necessarily of lower quality than rated
securities, but they may not be attractive to as many buyers.

     Prepayment/Call risk: Prepayment risk is the risk that the obligor on a
debt security may repay or "call" the debt before it is due. Most mortgage
backed, asset backed, other public bond debt securities and 144A securities that
a Fund might own are exposed to this risk. U.S. Government securities have
minimal exposure to this risk. Prepayment/call is most likely to occur when
interest rates have declined and a borrower can refinance the debt at a lower
interest rate level. Generally, a Fund reinvests the proceeds resulting from
prepayments in a lower yielding instrument. This results in a decrease in the
Fund's current yield. The values of securities that are subject to
prepayment/call risk also tend to increase less in response to declining
interest rates and decrease more in response to increasing interest rates than
would the value of otherwise similar securities that do not have prepayment or
"call" features.

     All Funds that invest in debt securities (other than the Money Market Fund)
may at times have some exposure to prepayment/call risk. The Funds most likely
to invest a significant portion of their assets in debt securities with
prepayment/call features are the Short-Term Bond, Bond Index, Active Bond,
Global Bond and High Yield Bond Funds. The Managed, Aggressive Balanced, and
Global Balanced, Short-Term Bond, Bond Index, Active Bond, Global Bond, and High
Yield Bond Funds may also invest in these securities.

     Risks of "zero coupon" instruments: All of the Funds may, in varying
degrees, invest in debt instruments that provide for payment of interest at the
maturity date of the instrument (or payment of interest in the form of
additional securities), rather than payment of interest in cash periodically
over the life of the instrument. The values of such instruments tend to respond
more to changes in interest rates than do otherwise comparable debt obligations
that provide for periodic interest payments. The Funds most likely to invest a
significant amount of their assets in instruments that are subject to this
volatility risk are the Managed, Aggressive Balanced, Real Estate Equity, Global
Balanced, Short-Term Bond, Bond Index, Active Bond, Global Bond, and High Yield
Bond Funds. However, all Funds that invest in debt securities may at times have
some exposure to this risk.

3.   Investing in Equity Securities

     All of the Funds intend to invest to some degree in common stock or other
equity securities, except for the Short-Term Bond, Bond Index, Active Bond,
Global Bond, and Money Market Funds. All of the Funds that invest in equity
securities expect to make such securities their primary investment (except for
the Managed, High Yield Bond and Global Balanced Funds, which may nevertheless
do so in the discretion of their subadvisers). Though investing in equity
securities, the Managed, Aggressive Balanced, and Global Balanced Funds also
expect, under normal conditions, to invest a substantial amount of their assets
in debt obligations.

     General risks of investing in equity securities are discussed in the
balance of this Section 3.

     Equity risk: Investments in common stock or other equity securities
historically have offered a higher rate of return than money market instruments
or longer term debt securities. However, the risks associated with equity
securities also tends to be higher, because the investment performance of equity
securities depends upon factors which are difficult to predict. The fundamental
risk associated with any equity portfolio is the risk that the value of the
investments it holds might decrease in value. Equity security values may
fluctuate in response to the activities of an individual company or in response
to general market, interest rate, and/or economic conditions.

     Market capitalization risk: Another indication of the relative risk of a
common stock investment is the size of the company, which is typically defined
by reference to its "market capitalization." Market capitalization is computed
by multiplying current market price of a share of the company's stock by the
total number of its shares outstanding.

                                       7
<PAGE>

     Investing in larger capitalization companies generally involves a lesser
degree of risk than investing in smaller capitalization companies. Conversely,
investing in the equity securities of smaller companies involves greater risks
and potential rewards than investing in larger, more established companies.
Small capitalization companies, in particular, often have limited product lines,
markets or financial resources, and they may depend upon a small group of
inexperienced managers. Investments in such companies can be both more volatile
and more speculative. These securities may have limited marketability and are
subject to more abrupt or erratic market movements than securities of larger
companies or the market in general.

     Three capitalization levels are currently used by the Trust: large, medium
("mid"), and small. Each of these capitalization levels will be defined by
reference to the Russell 3000(R) Index. The Russell 3000(R) Index Index is a
broad market index and is representative of the U.S. stock markets with a total
capitalization of $13.4 trillion at the end of 1999.1

     .    Large cap: Companies having a capitalization within the range of the
          300 largest companies in the Russell 3000(R) Index will be considered
          to be large capitalization ("large cap") companies. At the end of
          1999, each of the largest 300 companies in the Russell 3000(R) Index
          had a capitalization greater than $ 7.9 billion.

     .    Mid cap: Companies having a capitalization within the range of the 250
          to 1000 largest companies in the Russell 3000(R) Index will be
          considered to be "mid cap." At the end of 1999, such mid cap companies
          had capitalizations ranging from $1.4 billion to $9.7 billion.

     .    Small cap: Companies having a capitalization within the range of the
          remaining companies in the Russell 3000(R) Index will be considered to
          be small capitalization ("small cap") companies. At the end of 1999,
          none of these smallest companies in the Russell 3000(R) Index had a
          market capitalization of more than $1.4 billion.

The above parameters for large cap, mid cap and small cap are adjusted at the
end of each calendar quarter to reflect changes in the market capitalization of
the Russell 3000(R) Index.

     The equity securities of the Managed, Aggressive Balanced, Growth & Income,
Equity Index, Large Cap Value, Large Cap Value CORE, Large Cap Growth, Large Cap
Aggressive Growth, Global Equity, Global Balanced and International Equity Index
Funds are generally expected to represent primarily companies that qualify as
large cap issuers. These Funds also may invest in the equity securities of
companies that qualify as small and mid cap issuers.

     The equity securities of the Large/Mid Cap Value, International Equity and
International Opportunities Funds are generally expected to represent primarily
large and mid cap issuers. These Funds also may invest in the equity securities
of companies that qualify as small cap issuers.

     The equity securities of the Mid Cap Value, Mid Cap Growth, Fundamental Mid
Cap Growth, and Mid Cap Blend Funds are generally expected to represent
primarily companies that qualify as mid cap issuers. These Funds also may invest
in the equity securities of companies that qualify as small or large cap
issuers.

     The equity securities of the Small/Mid Cap Value, Small/Mid Cap Growth, and
Small/Mid Cap CORE Funds are generally expected to represent companies that are
small cap and mid cap issuers. These Funds also may invest in the equity
securities of companies that qualify as large cap issuers.

- -------------------
1 The Russell 3000(R) Index is a service mark of Frank Russell Company, which
does not sponsor and is not in any way affiliated with the Trust. Inclusion in
the index in no way implies an opinion as to its attractiveness or
appropriateness as an investment.

                                       8
<PAGE>

     The Small Cap Value and Small Cap Growth Funds are generally expected to
invest primarily in equity securities of companies that qualify as small cap
issuers. Although these Funds also may invest significant amounts in the equity
securities of companies that qualify as mid cap issuers, it is expected that
they would rarely invest in the equity securities of companies that qualify only
as large cap issuers.

     The Emerging Markets Equity Fund has broad latitude to invest in companies
of any size.

     The Real Estate Equity Fund invests in real estate equity securities that
have historically been primarily mid cap, but it may also invest in small cap or
large cap equity securities.

4.   Investing in Real Estate Securities

     The Real Estate Equity Fund invests primarily in companies with activities
related to the real estate industry, such as real estate investment trusts
("REITs") that own commercial and multifamily residential real estate, real
estate operating companies ("REOCs") that derive the majority of their revenue,
income or asset value from real estate and other companies engaged in non-real
estate businesses but whose real estate holdings are significant in relation to
the market value of their common stock.

     The securities purchased will be principally common stock (and securities
convertible into or with rights to purchase common stock) but a portion of the
Fund may be invested in preferred stock. The Fund may also invest in commercial
mortgage securities (debt obligations secured by commercial property),
collateralized mortgage obligations (mortgage pass through securities secured by
commercial mortgage pools) and master limited partnerships from time to time,
but does not do so on the date of this Statement of Additional Information.

     In addition to the Real Estate Equity Fund, all of the other Funds (except
for the Money Market Fund) may have some exposure to real estate risks through
investments in companies engaged in real estate related businesses or
investments in debt instruments secured by real estate.

     Risks of real estate securities: Generally speaking, real estate securities
may be affected by risks similar to those resulting from the direct ownership of
real estate, as well as by market risks due to changes in interest rates and by
the overall volatility of the equity markets. The market value of shares in
equity real estate investment trusts and commercial property companies, in
particular, is heavily dependent upon the value of their underlying properties.
Overbuilding, declines in local or regional economic conditions, financial
difficulties on the part of major tenants and increases in real estate taxes and
operating expenses all could decrease the value of the real estate investments.

5.   Investing in Foreign Securities

     Investments in foreign securities may be made in a foreign-denominated
security, or in the form of American Depositary Receipts ("ADRs"), European
Depositary Receipts ("EDRs") or other securities representing underlying shares
of foreign securities. ADRs, EDRs and other securities representing underlying
shares of foreign securities may not necessarily be denominated in the same
currency as the securities into which they may be converted, but rather in the
currency of the market in which they are traded. ADRs are receipts, typically
issued by an American bank or trust company, which evidence ownership of
underlying securities issued by a foreign corporation. EDRs are receipts issued
in Europe by banks or depositories which evidence a similar ownership
arrangement. Generally, ADRs are designed for use in U.S. securities markets;
while EDRs are designed for use in European securities markets.

Investments in debt securities issued by foreign issuers may be made directly in
foreign-denominated debt instruments or in the form of U.S. dollar denominated
debt securities issued by foreign issuers and publicly traded in the United
States ("Yankees") or in Europe ("Eurobonds").

The International Equity Index, International Equity, International
Opportunities, Global Equity, Emerging Markets Equity, Global Bond and Global
Balanced Funds invest primarily in foreign securities, including foreign-
denominated securities. To a lesser extent, the Managed, Aggressive Balanced
High Yield Bond, Large Cap Value

                                       9
<PAGE>

and Mid Cap Growth Funds may also invest in foreign securities, including
foreign-denominated securities. The Large Cap Growth, Small Cap Growth, Mid Cap
Blend, Large Cap Value CORE, Large/Mid Cap Value, Mid Cap Value, Small/Mid Cap
Growth, Large Cap Aggressive Growth, Small/Mid Cap CORE, Small/Mid Cap Value,
Real Estate Equity, Growth & Income, Small Cap Value, and Equity Index Funds may
invest in ADRs to a limited extent. The Short-Term Bond, Bond Index and Active
Bond Funds may invest in foreign debt securities only if denominated in U.S.
dollars (i.e., Yankees and Eurobonds).

The Emerging Markets Equity Fund invests primarily in developing countries
commonly known as "emerging markets." To a lesser extent, the Global Equity,
Global Balanced, International Equity Index, International Equity, International
Opportunities, Bond Index, Global Bond, Active Bond, and High Yield Bond Funds
may also invest in emerging markets.

     Risks of investing in foreign securities are discussed in the paragraphs
that follow:

     Currency risks: When a Fund buys foreign-issued securities, it usually must
pay for those securities in the local currency. Therefore, the Fund must convert
funds into the local currency to the extent necessary for this purpose.
Similarly, when a Fund sells a foreign security, it may receive payment in the
local currency. Therefore, if the Fund does not wish to continue to hold that
currency, it must enter into a transaction disposing of it.

     In these ways, therefore, a Fund may temporarily hold foreign currency in
order to facilitate the purchase and sale of foreign securities. This exposes
the fund to the risk that the foreign currency's value could, while the Fund was
temporarily holding that currency, decline relative to the U.S. dollar. This
could result in a loss to the Fund, because the Fund's assets and shares are
valued in U.S. dollars. On the other hand, the Fund could experience gains if
the foreign currency's value, relative to the U.S. dollar, increases during the
period when the Fund holds that currency.

     More fundamentally, however, because the Fund values its assets and shares
in U.S. dollars, the Fund's gains and/or losses on investments that are
denominated or traded in foreign currencies will depend in part on changes in
the value of that currency relative to the U.S. dollar. This exposes the Fund to
the risk of loss if that foreign currency loses value, as well as the
possibility of gains if that currency gains value, relative to the U.S. dollar.

     The Funds may (but are not required to) employ certain strategies to limit
their risks or otherwise manage their exposure to foreign currencies. Such
currency management techniques, as well as the risks that those techniques
themselves present, are discussed in Sections 6. - 10. below.

     Also, a risk exists that a foreign country may have or implement
restrictions on transactions in its currency that prevent a Fund from
effectively managing or reducing its exposure to that currency, even after the
Fund has disposed of any securities denominated or traded in that currency.

     The risks associated with foreign currency conversions are not present in
investments in Yankees and Eurobonds because these debt securities are U. S.
dollar denominated.

     Political and economic risk: Foreign securities often are subject to
heightened political and economic risks, particularly in emerging markets or
other underdeveloped or developing countries, which may have relatively unstable
governments and economies based on only a few industries. Foreign governments
may take over the assets or operations of a company, may impose additional
taxes, or may place limits on the removal of the Fund's assets from that
country. However, investments in foreign securities also offer the opportunity
to diversify holdings and to invest in economies whose growth may outpace that
of the United States.

     Regulatory risk: Generally, there is less government supervision of foreign
markets. Foreign issuers generally are not subject to uniform accounting,
auditing, and financial reporting standards and practices applicable to domestic
issuers. There may be less publicly available information about foreign issuers
than domestic issuers. These risks may be greater in emerging markets or other
underdeveloped or developing countries.

                                      10

     Market risk: Foreign securities markets, particularly those of emerging
markets or other underdeveloped or developing countries, may be less liquid and
more volatile than domestic markets. Certain markets may require payment for
securities a Fund purchases before delivery of these securities to the Fund, and
delays may be encountered in settling securities transactions. In some foreign
markets, there may be limited protection against failures by other parties to
complete their transactions with a Fund. There may be limited legal recourse
against an issuer in the event of a default on a debt instrument held by a Fund.

     Transaction costs: Transaction costs of buying and selling foreign
securities, including brokerage, tax, and custody costs, are generally higher
than those involved in domestic transactions. This is particularly true for
investments in emerging markets, or other underdeveloped or developing
countries.

6.   Using Forward Exchange Contracts to Manage Currency Exposure

     Transaction hedging and portfolio hedging: When a Fund anticipates having
to purchase or sell a foreign currency to facilitate a foreign securities
transaction, it may wish to "lock in" the current exchange rate for that
currency (vis-a-vis the U.S. dollar) and thus avoid (in whole or in part)
exposure to further changes in that rate that could occur prior to when the
purchase or sale proceeds are actually paid. This is called "transaction
hedging."

     A Fund can do transaction hedging by purchasing or selling foreign
currencies in the "spot" (i.e., cash) market. Alternatively, the following Funds
may use "forward" currency foreign exchange purchase or sale contracts for
transaction hedging: the Managed, Aggressive Balanced, Large Cap Value, Mid Cap
Growth, Global Equity, Global Balanced, International Equity Index,
International Equity, International Opportunities, Emerging Markets Equity,
Global Bond, and High Yield Bond Funds. In a forward exchange contract, the Fund
purchases or sells a specific amount of foreign currency, at a price set and
time set in the contract, which may be any fixed number of days in the future.

     These same Funds may also use forward foreign exchange contracts to reduce
their exposure to changes (relative to the U.S. dollar) in the value of a
foreign currency during a period of time when the Fund owns securities that are
denominated, exposed to or traded in that currency. This is called "portfolio
hedging." Except as described in the paragraph immediately below for certain
funds, the Funds may not engage in portfolio hedging with respect to the
currency of a particular country to an extent greater than the aggregate market
value (at the time of establishing the hedge) of securities held by that Fund
which are denominated, exposed to or traded in that particular foreign currency.
The Funds may or may not attempt to hedge some or all of their foreign portfolio
positions. Rather, they will enter into such transactions only to the extent, if
any, deemed appropriate by their subadvisers. Furthermore, no Fund will use
forward foreign currency exchange contracts for the purpose of leveraging the
Fund's currency exposure.

     For purposes of transaction hedging or portfolio hedging, the Managed,
Aggressive Balanced, Mid Cap Growth, Global Equity, Global Balanced, Global
Bond, International Equity Index, International Equity, Emerging Markets Equity,
and International Opportunities Funds may use forward exchange contracts on a
"proxy" currency, instead of the currency being hedged. A proxy currency is one
that the subadviser believes will bear a close relationship to the currency
being hedged and believes will approximately equal the performance of such
currency relative to the U.S. dollar. Nevertheless, changes in the value of the
currency being hedged may not correspond to changes in the value of the proxy
currency as expected, which could result in the currency hedge being more
favorable or less favorable to the Fund than the subadviser had expected.

     Other techniques for managing currency exposure: The Managed, Aggressive
Balanced, Mid Cap Growth, Global Equity, Global Balanced, International Equity
Index, International Equity, International Opportunities, Emerging Markets
Equity, and Global Bond Funds may use additional techniques when their
subadvisers believe that the currency of a particular country may suffer a
significant decline against the U.S. dollar or against another currency. In that
case, these Funds may enter into a forward currency contract to sell, for a
fixed amount of U.S. dollars or other appropriate currency, the amount of
foreign currency approximating the value of some or all of the Fund's securities
denominated in, traded in, or exposed to such foreign currency. The currency
contract may call for the Fund to receive a currency other than U.S. dollars,
for example, if such other currency is believed to be undervalued or necessary
to bring the Fund's overall exposure to various currencies into a more

                                      11
<PAGE>

desirable balance. For similar purposes, the Managed, Aggressive Balanced,
Global Balanced, Emerging Markets Equity, International Opportunities,
International Equity, Mid Cap Growth and Global Bond Funds may also enter into
contracts to purchase, for a fixed amount of U.S. dollars, or other appropriate
currency, an amount of foreign currency corresponding to the value of some of
the Fund's securities.

     Asset segregation requirements for forward exchange contracts: A Fund may
"cover" its obligations under outstanding forward currency sale contracts by
maintaining portfolio securities denominated, exposed to or traded in the
currency of such contracts or of an appropriate proxy currency. To the extent a
Fund does not thus cover all of its forward currency sales positions with its
portfolio securities, or if it has outstanding any forward currency purchase
contracts, the Funds' custodian will segregate cash or liquid assets in a
separate account of the Fund in an amount at all times at least equal to the
value of the Fund's net obligation with respect to forward contracts in a
particular currency or, in the case of the Global Balanced Fund only, the value
of that Fund's net "out of the money" obligation (If any) with respect to all of
the Fund's outstanding forward currency contracts. If the value of the portfolio
securities used to cover a position or the value of the assets in the segregated
account declines, the Fund will find additional "cover" or additional cash or
liquid assets will be placed in the account so that the value of the account
will at least equal the required amount described in the preceding sentence.

7.   Using Options on Currencies to Manage Currency Exposure

     The Managed, Aggressive Balanced, Mid Cap Growth, Global Equity, Global
Balanced, International Equity Index, International Equity, International
Opportunities, Emerging Markets Equity, Global Bond, and High Yield Bond Funds
may also purchase and write put and call options on foreign currencies for the
same purposes as those Funds could use forward foreign exchange contracts (as
discussed in Section 6. above). This could include options traded on U.S. and
foreign exchanges, as well as those traded in "over-the-counter" markets.

     The characteristics and risks of these currency option transactions are
similar to those discussed in Sections 15. - 16. below with respect to put and
call options on securities.

     Call options on foreign currencies written by a Fund will be "covered,"
which means that the Fund will own at all times at least an equal amount of, or
an offsetting position in, the underlying foreign currency.

     Asset segregation requirement for currency put options written by a Fund:
With respect to put options on foreign currencies written by a Fund, the Fund
will establish a segregated account with its custodian bank consisting of cash,
U.S. Government securities or other high grade liquid debt securities in an
amount equal at all times to the amount the Fund would be required to deliver
upon exercise of the put.

8.   Using Currency Futures Contracts and Options Thereon to Manage Currency
     Exposure.

     Any Fund may use currency futures contracts and options thereon for the
same purposes and to the same extent as that Fund could use forward foreign
exchange contracts (as discussed in Section 6. above). The characteristics and
risks of such futures and options transactions are similar to those discussed in
Sections 16. - 19. below for other transactions in futures contracts and options
thereon. All transactions in currency futures and options thereon also would be
subject to the applicable limitations in Section 20. below.

9.   Using Certain Other Derivative Instruments to Manage Currency Exposure

     As discussed in Section 21. below, several of the Funds may use currency
"swaps," "caps," "floors," and "collars" for the same purposes as those Funds
could use forward foreign exchange contracts (as discussed in Section 6. above).
The characteristics and risks of such "derivative" transactions, as discussed in
Section 21., are generally also applicable when such instruments are used for
currency management purposes.

                                      12
<PAGE>

10.  Using Foreign Currency Exposure Management Strategies (General
     Considerations and Risks)

     The foreign currency management techniques discussed in Sections 6. - 9.
above do not eliminate fluctuations in the prices of portfolio securities or
prevent losses if the prices of such securities decline. The Funds are not
obligated to try to hedge against any change in the value of any currency. Even
if a Fund wished to do so, there is no assurance that market conditions would be
such as to make such hedging possible.

     Moreover, even where a Fund establishes positions designed to manage its
foreign currency exposure, there is no assurance that this will be beneficial to
the Fund. Such positions may cause a Fund to forego gains that it otherwise
could have achieved or incur costs and losses that it would not otherwise have
incurred. (In general the cost to the Funds of engaging in foreign currency
management transactions varies with such factors as the currency involved, the
type and duration of the instrument being used for this purpose, and the market
conditions then prevailing.) It is entirely possible, therefore, that any effort
to manage a Fund's currency exposure could have a negative effect on the Fund's
investment performance.

     In general, the more foreign securities a given Fund invests in, the
greater its currency management activities are likely to be. Also, the Managed,
Aggressive Balanced, Mid Cap Growth, Global Equity, Global Balanced,
International Equity Index, International Equity, International Opportunities,
Emerging Markets Equity and Global Bond Funds may use certain of these same
types of instruments in currency management strategies that expose those Funds
to currencies other than the U.S. dollar. Although this would not be done for
the purpose of "leveraging" the Fund's overall exposure to fluctuations in
currency values, such strategies could expose those Funds to greater risks of
loss and greater volatility than they otherwise would experience.

11.  Reallocating a Fund's Assets Among Asset Classes

     The continual reallocation of assets among the major asset classes (e.g.,
stocks, bonds, and cash) involves the risk that the subadviser may reduce the
Fund's holdings in an asset class whose value increases unexpectedly, or may
increase the Fund's holdings in an asset class just prior to that asset class
experiencing a loss of value. The Managed, Aggressive Balanced, and Global
Balanced Funds tend to exercise broad discretion in reallocating assets across
asset classes. The Global Bond and Global Equity Funds intend to exercise
discretion to reallocate assets across domestic and international asset classes.

     All of the other Funds, with the exception of the Money Market Fund,
generally allow the subadviser some latitude to allocate across asset classes.
Nevertheless, this latitude is expected to be exercised to a lesser degree than
in the case of the Managed, Aggressive Balanced, and Global Balanced Funds.

12.  Adopting a Temporary Defensive Strategy

     All of the Funds, except the Money Market Fund, may (but are not required
to) adopt a defensive investment posture if the subadviser believes the
investment environment for the Fund is negative. Such a defensive posture would
involve reallocating some or all of a Fund's assets in a manner different from
that contemplated by its primary investment objective and strategies.

     Most of the Funds are not limited as to the types of investments they could
use temporarily for defensive purposes. Thus, for example, a small cap equity
Fund might temporarily invest in stocks of larger cap companies or in high
quality, short term debt securities. A bond Fund might shorten maturities or
tighten its investment quality parameters. An international Fund might, for
example, limit the countries it would invest in or temporarily invest only in
high quality, short-term debt securities in the United States.

     There can be no assurance that the transaction costs and lost investment
opportunities will not outweigh any benefits to a Fund that attempts to adopt a
defensive strategy.

                                      13

13.  Investing With an Index-Based Objective

     The Equity Index, International Equity Index, and Bond Index Funds expect
to invest substantially all of their assets in equity or debt securities within
their investment objectives and policies at all times. Accordingly, these Funds
may carry more risk in times of declining markets than Funds that are more
likely to adopt a defensive investment posture in such circumstances by
reallocating their assets in a manner different from that contemplated by their
primary investment objective and strategies.

     Investments in the Equity Index, International Equity Index, and Bond Index
Funds each involve the risk that the Fund will be unable to match the
performance of its corresponding target index. Each Fund's ability to do so is
affected by (a) the size and timing of cash flows into and out of that Fund, (b)
the level of the Fund's expenses, including commissions and "spreads," on its
portfolio transactions, other portfolio management expenses, and other operating
expenses, and (c) the degree of success of the techniques employed by the Fund's
subadviser. Further, if the size of a Fund limits the number of issues that the
Fund can purchase, or that size is relatively small in relation to cash flows,
there is a greater possibility that the Fund may be unable to match the
performance of the corresponding target index.

     The S&P 500 Index: The S&P 500 is an index that is constructed by the
Standard & Poor's Corporation ("Standard & Poor's" or "S&P"), which chooses
stocks on the basis of market values and industry diversification. Most of the
largest 500 companies listed on U.S. stock exchanges are included in the index.
Additional stocks that are not among the 500 largest stocks, by market value,
may be included in the S&P 500 for diversification purposes. The index is
capitalization weighted -- that is, stocks with a larger capitalization (shares
outstanding times current price) have a greater weight in the index. Selection
of a stock for inclusion in the S&P 500 Index in no way implies an opinion by
S&P as to its attractiveness as an investment.

     The Lehman Brothers Government/Corporate and Aggregate Bond Indexes: The
Lehman Brothers Government/Corporate Index (the "Government/Corporate Index") is
intended to measure the performance of the domestic, fixed-rate investment grade
debt market. The Government/Corporate Index is composed of (1) all public
obligations of the U.S. Government, its agencies and instrumentalities
(excluding "flower" bonds and pass-through

                                      14
<PAGE>

issues, such as GNMA certificates) and (2) all publicly issued, fixed-rate,
non-convertible, investment grade, U.S. dollar-denominated, SEC-registered
obligations of domestic corporations, foreign governments and supranational
organizations. Securities in the index generally have at least $150 million par
amount outstanding and at least 1 year remaining to maturity.

     The Lehman Brothers Aggregate Bond Index (the "Aggregate Bond Index")
covers the U.S. investment grade fixed-rate bond market, including government
and corporate securities, agency mortgage pass-through securities, and asset-
backed securities. The Aggregate Bond Index covers those securities in the
Government/Corporate Index, plus those covered by the Lehman Mortgage-Backed
Securities Index ("MBS Index") and the Lehman Asset-Backed Securities Index
("ABS Index"). The MBS Index covers fixed-rate securities backed by mortgage
pools of the Government National Mortgage Association, the Federal Home Loan
Mortgage Association, and the Federal National Mortgage Association. The ABS
Index covers several subsectors -- including credit and charge cards, auto,
utilities and home equity loans -- and includes pass-through, "bullet," and
controlled amortization structures.

     All non-government issues in the Government/Corporate Index and the
Aggregate Bond Index are rated at least Baa by Moody's Investors Service, Inc.
("Moody's") or, if unrated by Moody's, BBB by Standard & Poor's Ratings Group
("Standard & Poor's").

     All securities in the Government/Corporate Index and the Aggregate Bond
Index issued by non-U.S. entities are denominated in U.S. dollars.

appropriateness as an investment.

     The MSCI EAFE GDP Index: The MSCI EAFE GDP Index weights countries such
that a country with a larger GDP will have a greater weight in the index. Stocks
within those countries are capitalization weighted; that is, stocks with a
larger capitalization have a greater weight in the index.

     The Trust and the insurance products supported by the Trust are not

14.  Investing on a Non-Diversified Basis

     The Large Cap Aggressive Growth, Mid Cap Growth and Global Balanced Funds
are "non-diversified Funds." Non-diversified Funds are less restricted in the
extent to which they may invest more than 5% of their assets in any issuer or
purchase more than 10% of the voting securities of any issuer. Because a
relatively high percentage of a non-diversified Fund's assets may be invested in
the obligations of a limited number of issuers, the value of that Fund's shares
may be more volatile and more susceptible to any single economic, political, or
regulatory event, or to credit and market risks associated with a single issuer,
than would the shares of a diversified Fund.

15.  Using Options (Generally)

     Most of the Funds may, in varying degrees, use options on the following
(which, for simplicity, may be referred to as the "subject" of an option):
currencies, securities, equity indexes, interest rate indexes, and financial
futures contracts. This Section 15. discusses certain characteristics and risks
that are generally common to all of these types of options. The Funds' use of
specific types is discussed in Sections [7. - 8. above and 16. - 20. below],
including characteristics and risks peculiar to those types of options or the
Funds' use of them.

     Purchasing "call" options: If a Fund (or anyone else) "purchases" a "call"
option, it pays a purchase price (often called a "premium") plus, in most cases,
a commission to the broker through whom the purchase was made. In return the
Fund (or other purchaser) has the right (but not the obligation), at or before a
specified future time (called the "expiration date"), to acquire a specified
amount of the option's subject (or the economic equivalent thereof) at a
specified price (called the "strike price" or "exercise price"). If the
purchaser of an option decides to exercise this right, we say the option has
been "exercised." If an option is never exercised before its expiration date, it
expires unexercised.

     A Fund (or other purchasers of a call option) may profit in one of two
ways.  First, the Fund may be able to exercise the call option at a date when
the value of the option's subject exceeds the purchase price of the option
(including any brokerage commission) plus the exercise price.  Whether the Fund
will be able to do this depends on how favorable those prices were and how the
value of the option's subject has changed since the option was purchased.

     Secondly, a Fund may profit from purchasing an option if the Fund is able
to sell the option (unexercised) at a profit sometime before its expiration
date. (As a practical matter, such a sale would generally be accomplished by
having the Fund sell (e.g., "write") an option identical to the option it owns,
thereby "netting out" the Fund's exposure to the position.) Whether such a
profit will be possible, of course depends on whether the then market price for
the option (less any commission payable on the sale) exceeds the option's
purchase price (including any related commission). In this regard, one of the
general risks of purchasing options is that, for a variety of reasons, the
market price of an option usually does not vary in the same way or to the same
extent as the value of the option's subject varies. Therefore, a Fund can lose
money purchasing a call option, even if the value of the option's subject
increases.

     The basic risk in purchasing an option is that, if the Fund never exercises
or sells the option at a profit, the Fund will lose the entire purchase price of
the option (plus any related commissions). That is the maximum amount the Fund
could lose, however.

                                      16
<PAGE>

     Selling or "writing" call options: Selling an option is commonly referred
to as "writing" an option. If the Fund (or anyone else) sells ("writes") a call
option, it receives the premium (less any commission) paid by the option's
purchaser and has the obligation to sell the option's subject to the purchaser
at the exercise price if the purchaser exercises the option before it expires.

     The Fund can make a profit writing a call option if the purchaser fails to
exercise the option (which usually would happen only if the value of the
option's subject were below the exercise price). In this case, the option's
purchase price (net of any commissions) would be a profit to the Fund.

     Alternatively, a Fund could profit from writing a call option if it is able
to subsequently purchase an identical option that would close out the Fund's
position at a profit. This could be done only if the market price of the option
then exceeded the Fund's initial purchase price by an amount greater than any
commissions payable by the Fund on the purchase or sale transactions. There is a
risk, however, that a Fund may be unable to do this, even if the value of the
call option's subject has declined. This is because, as noted above, the value
of an option does not vary in identical fashion to the value of the option's
subject.

     The risk of writing a call option is that, if the value of the option's
subject exceeds the option's exercise price, the option is almost sure to be
exercised. In that case, the Fund will suffer a loss to the extent that the
premium it received for writing the option (net of any commissions), plus the
exercise price it receives are less than the value of the option's subject at
the time of exercise. Therefore, the higher the value of the option's subject
rises, the greater the Fund's potential loss on an option it has written. A Fund
could cut off its further exposure in such a case by purchasing an identical
call option that would close out its position. The Fund would, however, probably
realize a loss on the transaction, because the purchase price it would have to
pay for that call option would probably have increased to reflect the increasing
value of the option's subject.

     Writing options on a "covered" basis. One way for a Fund to limit its risk
exposure on call options it has written is to "cover." A call option may be
considered "covered" if, as long as the option is outstanding, the writer
(seller) of the option owns assets that are identical to, or have the same or
similar investment characteristics to, the option's subject. In such a case, if
the value of the option's subject increases, the losses that the Fund will incur
on the call option it has written will tend to be offset by gains that Fund
earns on the assets it is holding to "cover" the option.

     Naturally, the more similar the assets held by the fund are to the option's
subject, the more assurance the Fund will have that its losses on call options
it has written will be "covered." How similar those assets must be varies
depending on the Fund and the type of covered option involved. More details in
this regard can be found in Sections 16. - 19. below.

     Purchasing and selling (writing) "put" options: A "put" option is the same
as a call option, except that a Fund (or any other person) that purchases a put
option, by paying the purchase price ("premium") has the right to sell (rather
than buy) the option's subject for a stated exercise ("strike") price.
Conversely, the seller (writer) of a put option receives the premium (net of any
commissions) but has the obligation to purchase the option's subject at its
exercise price if the option is exercised.

     Thus, if a Fund purchases a put option, its maximum potential loss would
equal the purchase price (plus any commissions thereon). On the other hand, if a
Fund sells (writes) a put option, the Fund could continue to experience
continuing losses while the option is outstanding, to the extent that the value
of the subject of the option continues to decline. If the subject lost its value
entirely, the Fund's maximum loss would equal the exercise price less the
premium (net of any commissions) that the Fund received initially for writing
the option. Because of this risk exposure, a Fund that writes a put option may
seek to "cover" that option with other assets that it owns. More details about
this can be found in Section 16. - 19. below.

     Accounting for options: The value of any option that the Fund has
purchased, and the amount of the Fund's obligation under any outstanding option
it has written, will vary as market prices change. These variations are
reflected daily in the Fund's calculation of its net asset value, so that such
value always reflects the estimated impact of current market conditions on all
of the Fund's option positions.

16.  Using Options on Securities in Certain Conservative Investment Strategies

     Except as otherwise noted below, the general discussion of options in
Section 15. above applies to this Section 16.

     Each of the Funds may write covered call options that are traded on
national securities exchanges, except for the Growth & Income, Real Estate
Equity,  and Money Market Funds.  By "covered" we mean that the Fund will
actually own the securities that are the subject of the option.

     The same Funds may purchase "protective" put options that are traded on
national securities exchanges.  By "protective", we mean that the Fund will
actually own the securities that are the subject of the option.  If the market
value of such underlying securities remains above the option's exercise price,
the Fund will, in effect, lose the premium it has paid for the option.  The
Fund, however, avoids the risk of loss on the underlying securities, to the
extent that the market value of the underlying securities falls below the
exercise price of the put option.

     Liquidity risk:  The Funds intend to write and purchase options only if the
subadviser believes that adequate liquidity exists.  If for any reason a Fund
cannot, however, close out its open option position when deemed advisable, the
Fund's investment performance could be adversely affected.

17.  Using Financial Futures Contracts, Options on Such Contracts and Options on
     Stock Indexes (General Considerations)

     Most of the Funds may, in varying degrees use financial futures contracts,
options on such futures and options on stock indexes.  This Section 17 discusses
certain characteristics and risks that generally pertain to these instruments,
regardless of the specific use to which they are put.  The Funds' specific uses
are discussed in Sections 7. - 8. above and 18. - 20. below, including specific
risks related to those risks.

     Financial futures contracts:  Financial futures contracts consist of
interest rate futures contracts, stock index futures contracts, and currency
futures contracts.

     An interest rate futures contract is a contract to buy or sell specified
debt securities at a future time for a fixed price.  A public market currently
exists for interest rate futures contracts on United States Treasury Bills,
United States Treasury Notes, bank certificates of deposit, and various other
domestic or foreign instruments and indexes.

     Stock index futures contracts bind purchaser and seller to delivery at a
future date specified in the contract of a cash amount equal to a multiple of
the difference between the value of a specified stock index on that date and
settlement price specified by the contract.  That is, the seller of the futures
contract must pay and the purchaser would receive a multiple of any excess of
the value of the index over the settlement price, and the purchaser must pay and
the seller would receive a multiple of any excess of the settlement price over
the value of the index.  A public market currently exists for stock index
futures contracts based on the Standard & Poor's 500 Stock Index, the Standard &
Poor's Midcap Index, the New York Stock Exchange Composite Index, the Value Line
Stock Index, and various other domestic or foreign indexes.

     A currency futures contract is a contract to buy or sell a specified amount
of another currency at a future time for a fixed price.

     Options on financial futures contracts:  The writer of an option on a
financial futures contract agrees to assume a position in such financial futures
contract having a specified price, if the purchaser exercises the option and
thereby assumes the opposite position in the financial futures contract.  If the
option purchaser would assume the sale side of the futures contract upon
exercise of the option, the option is commonly called a "put" option.  If the
option writer would assume the sale side, it is commonly called a "call" option.
As with other types of options, the party that writes the option receives a
premium for doing so, and the party that purchases an option pays a premium
therefor.  However, there is no exercise (or strike) price, as such.  Rather, if
the value of the futures contract moves

                                      18
<PAGE>

against the writer of the option, so that the option is (or is likely to be)
exercised, the option writer, in effect, has the obligation to pay those losses.

     More specifically, an option written by a Fund on a financial futures
contract requires the Fund to pay any amount by which the fluctuating price of
the underlying debt instrument or index exceeds (in the case of a call option)
or is less than (in the case of a put option) the price specified in the futures
contract to which the option relates.  Therefore, if the price of the debt
instrument or stock index on which the futures contract is based increases (in
the case of a call option written by a Fund) or decreases (in the case of a put
option written by a Fund), the Fund may incur losses that exceed the amount of
the premium received by the Fund for writing the option.

     Stock index options:  After payment of a specified premium at the time a
stock index option is entered into, the purchaser of a stock index call option
obtains the right to receive a sum of money upon exercise of the option equal to
a multiple of the excess of a specified stock index on the exercise date over
the exercise or "strike" price specified by the option.  The purchaser of a put
option obtains the right to receive a sum of money upon exercise of the option
equal to a multiple of any excess of the strike price over the stock index.  The
writer of a call or put stock index option receives a premium, but has the
obligation, upon exercise of the option, to pay a multiple of the difference
between the index and the strike price.  Thus, if the price of the stock index
on which an index option is based increases (in the case of a call option
written by a Fund) or decreases (in the case of a put option written by a Fund),
the Fund may incur losses that exceed the premium it received for writing the
option.

     Stock indexes for which options are currently traded include the Standard &
Poor's 100 and Standard & Poor's 500 Indexes.

     Margin requirements for futures and options:  When futures contracts are
traded, both buyer and seller are required to post an initial margin of cash or
U.S. Treasury Bills equaling as much as 5 to 10 percent or more of the contract
settlement price.  The nature of the margin requirements in futures transactions
differs from traditional margin payments made in securities transactions in that
margins for futures contracts do not involve the borrowing of funds by the
customer to finance the transaction.  Instead, a customer's margin on a futures
contract represents a good faith deposit securing the customer's contractual
obligations under the futures contract.  If the market moves against the Trust,
so that a Fund has a net loss on its outstanding futures contracts for a given
day, the Fund generally will be required to post additional margin to that
extent.  The margin deposit is returned, assuming the Trust's obligations have
been met, when the futures contract is terminated.

     Similar margin requirements will apply in connection with any transactions
in which a Fund writes any options.  This includes options on indexes and
futures contracts, as well as other types of options.

     Certain risks:  Financial futures, options thereon, and stock index
options, if used by a Fund, will in most cases be based on securities or stock
indexes the components of which are not identical to the portfolio securities
owned or intended to be acquired by the Fund and in connection with which such
instruments are used.  Furthermore, due to supply and demand imbalances and
other market factors, the price movements of financial futures, options thereon,
and stock index options do not necessarily correspond exactly to the price
movements of the securities, currencies, or stock index on which such
instruments are based.  These factors increase the difficulty of implementing a
successful strategy using futures and options contracts.

     The Funds generally will not take delivery of debt instruments pursuant to
purchasing an interest rate futures contract, nor make a delivery of debt
instruments pursuant to selling an interest rate futures contract.  Nor will the
Funds necessarily take delivery of or deliver currencies in connection with
currency futures contracts.  Instead, a Fund will more typically close out such
futures positions by entering into closing futures contract transactions.
Similarly, a Fund may wish to close out an option on a futures contract or an
option on an index by entering into an offsetting position in those instruments.

     Generally speaking, entering into closing transactions such as described
immediately above would not affect gains and losses of the Fund resulting from
market action prior to such closing transactions.  Moreover, there is a risk
that, at the time a Fund wishes to enter into such a closing transaction,
trading in futures or options could be interrupted, for example, because of
supply and demand imbalances arising from a lack of either buyers or sellers.

                                      19
<PAGE>

The futures and options exchanges also may suspend trading after the price has
risen or fallen more than the maximum amount specified by the exchange.
Exercise of options could also be restricted or delayed because of regulatory
restrictions or other factors.  Although the subadvisers will seek to avoid
situations where these factors would be likely to cause a problem for the Trust,
in some cases they could adversely affect particular Fund transactions in these
instruments.

     Asset segregation requirement for certain futures and options positions:  A
Fund will maintain at all times in a segregated account with its custodian cash
or high-grade liquid debt securities at least equal to the sum of the purchase
prices of all of the Fund's open futures purchase positions, plus the current
value of the securities underlying all of the Fund's open futures sales
positions that are maintained for purposes other than bona fide hedging, plus
the exercise price of all outstanding put options on futures contracts written
by the Fund, minus the amount of margin deposits with respect thereto as marked
to market each day.

18.  Using Financial Futures, Options Thereon, and Stock Index Options for
     Certain Hedging-Type Strategies

     This Section 18. should be read against the background of the generally
applicable information about options, futures and related risks that appears in
Sections 15. and 17. above.

     This Section 18. covers all Funds, except the Growth & Income, Real Estate
Equity, and Money Market Funds.  Specifically, with those exceptions, all Funds
may use exchange-traded financial futures contracts thereon, and, except for the
Active Bond Fun, they also may purchase exchange-traded put or call options on
stock indexes, for the purposes discussed below.

     It should be emphasized that none of the Funds is required to use any of
these strategies, and doing so is not a principal investment strategy of any of
the Portfolios.  Therefore, it should not be assumed that any particular Fund
will ever necessarily use any of these strategies to a significant extent.

     Hedging with financial futures contracts against market changes:  All Funds
covered by this Section 18. (except the Equity Index Fund) may use financial
futures contracts as a hedge to protect against possible changes in interest
rates and security prices.

     Thus, for example, to hedge against the possibility that interest rates or
other factors may result in a general decline in prices of equity securities of
a type owned by them, these Funds (other than the Equity Index Fund) may sell
stock index futures contracts.  Similarly, to hedge against the possibility that
increases in interest rates may adversely affect the market values of debt
securities held by them, these Funds (other than the Equity Index and Large Cap
Value CORE Funds) may enter into interest rate futures sale contracts.

     Establishing market exposure and managing cash flow with financial futures
contracts:  On the other hand, purchasing futures contracts could enable a Fund
to take the approximate economic equivalent of a substantial position in bonds
or equity securities.  Thus, the following Funds may purchase and sell stock
index and interest rate futures to maintain market exposure and manage cash
flows:  the Managed, Aggressive Balanced, Equity Index, Large Cap Value CORE,
Large Cap Growth, Large Cap Aggressive Growth, Large/Mid Cap Value, Mid Cap
Growth, Fundamental Mid Cap Growth, Mid Cap Blend, Mid Cap Value, Small/Mid Cap
CORE, Small/Mid Cap Value, Small/Mid Cap Growth, Small Cap Growth, Global
Equity, Global Balanced, International Equity Index, International Equity,
International Opportunities, Emerging Market Equity, Short-Term Bond, Bond
Index, Active Bond, Global Bond, and High Yield Bond Funds.

     Managing foreign currency exposure with foreign currency futures contracts:
Any Fund may use foreign currency futures contracts to the same extent and in
the same manner as it is authorized to use forward foreign exchange contracts in
Section 6. above.

                                      20

<PAGE>

      Using options on futures contracts and options on stock indexes for the
foregoing purposes:  Each Fund that this Section 18. authorizes to use financial
futures contracts also may purchase options on appropriate financial futures
contracts and (except for the Active Bond Fund) stock indexes for any purpose
and to the extent that it could use financial futures contracts as discussed
above.

     Limitations on "long" positions for certain Funds: The Large Cap Value CORE
Portfolio may not purchase financial futures contracts, except for currency
futures. The following limitation applies to the Managed, Aggressive Balanced,
Equity Index, Large Cap Aggressive Growth, Large/Mid Cap Value Fundamental Mid
Cap Growth and Mid Cap Blend Funds.  These Funds may purchase financial futures
contracts, purchase call options on financial futures options or purchase call
options on equity indexes only if (a) they intend to purchase securities (or, in
the case of the Aggressive Balanced, Equity Index, Large Cap Aggressive Growth,
Large/Mid Cap Value, Fundamental Mid Cap Growth, and Mid Cap Blend Funds, wish
to establish or maintain market exposure to securities that the Fund would be
authorized to purchase) and (b) the values of such securities are expected to
change by approximately the same amount as the value of the futures or options
contracts being used to hedge them.

     Risks of hedging-type strategies:  If, after a Fund establishes a hedge
position, the value of the securities or currencies being hedged moves in the
opposite direction from that anticipated, the Fund as a whole will perform less
well than it would have had it not entered into the futures or option
transaction.

     The success of the Funds in using hedging-type techniques depends, among
other things, on the subadviser's ability to predict the direction and
volatility of price movements in the futures or options markets, as well as the
securities markets and, in some cases, currency markets, and on the subadviser's
ability to select the proper type, time and duration of option or futures
contracts.  Certain of the subadvisers have limited experience in utilizing
these hedging-type techniques, and there can be no assurance that these
techniques will produce their intended result.

     The prices of the futures and options contracts used for hedging-type
strategies may not vary as contemplated in relation to changes in the price of
the securities or currencies being hedged.  Accordingly, there is a risk that
transactions in these instruments, if used by a Fund, may not in fact offset the
impact of adverse market developments in the manner or to the extent
contemplated or that such transactions may result in losses to the Fund which
would not be offset by gains with respect to corresponding portfolio securities
owned or to be purchased by that Fund.  Hedging-type transactions also may be
more, rather than less, favorable to a Fund than originally anticipated.

19.  Using Options and Futures In Potentially More Aggressive Strategies

     This Section 19. should be read against the background of the generally
applicable information about options, futures, and related risks that appears in
Section 15., 17. and 18. above.

     This Section 19. applies only to the Managed, Aggressive Balanced, Large
Cap Value CORE, Mid Cap Growth, Small/Mid Cap CORE,  Small/Mid Cap Growth, Small
Cap Growth, Global Equity, Global Balanced, International Equity Index,
International Equity, Emerging Markets Equity, Short-Term Bond, Bond Index, l
Global Bond, and High Yield Bond Funds.  The option and futures strategies
discussed in this Section are in addition to those discussed for those (and
other) Funds in Sections 7., 8., 16., and 18. above.

     Writing certain types of options:  The Managed, Aggressive Balanced, Large
Cap Value CORE, Mid Cap Growth, Small/Mid Cap CORE, , Small/Mid Cap Growth,
Small Cap Growth, Global Equity, Global Balanced, International Equity Index,
International Equity, Emerging Markets Equity, Short-Term Bond, Bond Index,
Global Bond, and High Yield Bond Funds may write "covered" put options on
securities.  In addition, the Managed, Aggressive Balanced, Large Cap Value
CORE, Mid Cap Growth, Small/Mid Cap CORE, , Small/Mid Cap Growth, Small Cap
Growth, Global Equity, Global Balanced, International Equity Index,
International Equity, Short-Term Bond, Bond Index, Global Bond, and High Yield
Bond Funds may also write covered put and call options on indexes composed of
securities in which the Fund may invest.  Such index options may be written in
any manner that the Fund in question is authorized to write options on specific
securities it owns.

                                      21
<PAGE>

      A put option written by a Fund will be deemed to be "covered" if the Fund
maintains in a segregated account with its custodian cash, U.S. Government
securities or other high-grade liquid debt securities with a value at all times
at least equal to the exercise price of the put.  Put and call options written
by Funds will also be considered to be "covered" to the extent that the Fund's
liabilities under these options are fully offset by its rights under put or call
options purchased by the Fund.

     Purchasing certain types of options.   The Managed, Aggressive Balanced,
Large Cap Value CORE, Mid Cap Growth, Small/Mid Cap CORE,  Small Cap Growth,
Global Equity, Global Balanced, International Equity Index, International
Equity, Emerging Markets Equity, , Global Bond, and High Yield Bond Funds may
purchase put and call options on securities in which it may invest, without
specific restriction as to the circumstances of such purchases.  Similarly, each
of these Funds, as well as the Small/Mid Cap Growth and Short-Term Bond Funds,
may purchase put and call options on indexes composed of securities in which the
Fund may invest, without specific restriction on the circumstances of such
purchases.

     Option purchases of the type covered in the preceding paragraph would have
to be consistent with the Fund's investment objective.  Also, each of the above-
listed Funds is subject to the limitation on certain futures and options
transactions described in Section 20.

     Using options traded over-the-counter or on foreign exchanges:  The
Managed, Aggressive Balanced, Large Cap Value CORE, Mid Cap Growth, Small/Mid
Cap CORE, Small/Mid Cap Growth, Small Cap Growth, Global Equity, Global
Balanced, International Equity Index, International Equity, Emerging Markets
Equity, Short-Term Bond, Bond Index,  Global Bond, and High Yield Bond Funds may
also use options on securities and options on indexes that are traded "over-the-
counter" or on foreign exchanges, in any manner that they would be permitted to
use such options that were traded on domestic exchanges.  These Funds will
engage in over-the-counter options only with member banks of the Federal Reserve
System and primary dealers in U.S. Government securities.  These Funds will
treat over-the-counter options they have purchased and assets used to cover
over-the-counter options they have written as illiquid securities.  However,
with respect to options written with primary dealers in U.S. Government
securities pursuant to an agreement requiring a closing purchase transaction at
a formula price, the amount of illiquid securities may be calculated with
reference to the formula price.

     Using futures contracts and options on futures contracts for certain
purposes:  The Managed, Aggressive Balanced, Large Cap Value CORE, Mid Cap
Growth, Small/Mid Cap CORE, Small/Mid Cap Value, Small/Mid Cap Growth, Small Cap
Growth, Global Equity, Global Balanced, International Equity Index,
International Equity, Emerging Markets Equity, Short-Term Bond, Bond Index,
Active Bond, Global Bond, and High Yield Bond Funds may use futures contracts on
securities or on market indexes, and options on such futures contracts, without
specific restriction on the purposes of such transactions.  Nevertheless, such
transactions would have to be consistent with the Fund's investment objective.

     There is no specific overall limit on the amount of the assets these Funds
may devote to financial futures contracts and options thereon, even if such
contracts are not limited to hedging-type transactions.  Nevertheless (except
through the purchase of options, as discussed below) the Funds will not use
these techniques for purpose of "leveraging" the Fund's exposure to the
securities underlying any futures contract or option thereon or its exposure to
foreign currencies.  Although this limitation does not apply to options on
futures contracts that are purchased by a Fund, the total amount of premiums
paid by a Fund for such options that are not used for bona fide hedging is
(pursuant to the restrictions set forth in Section 20. below) limited to 5% of
the Fund's net assets.

     Risks of potentially more aggressive options and futures strategies:  As
outlined above, the Funds discussed in this Section 19. may engage in types of
options and futures transactions not permitted to the other Funds, including
over-the-counter options, writing covered put options, and more types of
transactions that are not solely for hedging-type purposes or that other may be
more speculative.  Also, even as to options and futures transactions of a type
that are permitted to other Funds, these Funds are, in certain cases, not as
limited regarding the amount of their assets that may be so employed.
Accordingly, to the extent that these Funds exercise their broader authority to
enter into options and futures transactions, they may incur greater risks than
the other Funds.

                                      22

20.  Limiting the Funds' Exposure to Certain Futures and Option Transactions.

     The  Equity Index, Large Cap Value, Large Cap Growth, Mid Cap Value, Small
Cap Value, and International Opportunities Funds will not enter into any
financial futures contract or purchase any option thereon, if, immediately
thereafter, the total amount of its assets required by commodities exchanges to
be on deposit as margin to secure its obligations under futures contracts, plus
the amount of premiums paid by the Fund for outstanding options to purchase
futures contracts, exceeds 5% of the market value of the Fund's total assets.

     The following limitation applies to all of the Funds that can invest in
financial futures contracts or options thereon, other than the Equity Index,
Large Cap Value, Large Cap Growth, Mid Cap Value, Small Cap Value and
International Opportunities Funds:  No such other Fund may purchase, sell or
write futures contracts or options thereon other than for "bonafide" hedging
purposes (as defined by the U.S. Commodity Futures Trading Commission) if
immediately thereafter the Fund's initial margin deposits on such outstanding
non-hedging futures and options positions, plus the amount of premiums paid by
the Fund for such outstanding non-hedging options on futures contracts, exceeds
5% of the market value of the Fund's net assets.  For the purpose of this
calculation, any amount by which an option is "in the money" at the time of its
purchase is excluded from the premium paid therefor.

     Nor will any of the Large Cap Value, Large Cap Value CORE, Large Cap
Growth, Mid Cap Value, Small Cap Value or International Equity Funds enter into
any transaction in interest rate, stock index or currency futures, or options
thereon, or stock index options, if the value of the securities being hedged by
all of such instruments would immediately thereafter be more than one-third of
the value of the Fund's total assets.  Nor will any Fund consider as "hedging"
any transaction that is intended to leverage the Fund's investment exposure to
the type of security being hedged or to leverage the Fund's currency exposure.

21.  Using Other Types of Derivative Instruments

     The Global Balanced, International Equity Index,  and High Yield Bond Funds
may engage in "swap" transactions (specifically interest rate, currency and
index swaps) and in the purchase or sale of related "caps," "floors," or
"collars."  The Emerging Markets Equity Fund may also engage in those
transactions and, in addition, may engage in equity swap transactions. The
Managed and Aggressive Balanced Funds may each invest up  to 10% of the
respective Fund's total assets (at the time the swap is entered into) in
currency and equity swaps for hedging purposes or for currency management
strategies as discussed in Section 6 above.   The International Equity Fund may
invest up  to 10% of its total assets (at the time the swap is entered into) in
currency and equity swaps, although it will use currency swaps only for hedging
purposes.  The Global Bond Fund may also use these derivative instruments, but
only for currency management strategies as discussed in Section 6. above.

     The nature and risks of these types of transactions are discussed further
in the paragraphs that follow.

     Interest rate swaps:  In a typical interest rate swap agreement, one party
agrees to make payments equal to a floating interest rate on a specified amount
(the "notional amount") in return for payments equal to a fixed interest rate on
the same amount for a specified period.  If a swap agreement provides for
payments in different currencies, the parties might agree to exchange the
notional amount as well.

     Provided the contract so permits, a Fund will usually enter into swaps on a
"net" basis: that is, the two payment streams are netted out in a cash
settlement on the payment date or dates specified in the instrument, with the
Fund receiving or paying, as the case may be, only the net amount of the two
payments.

     Interest rate caps, floors and collars:  The purchaser of an interest rate
cap or floor, upon payment of a fee, has the right to receive payments (and the
seller of the cap is obligated to make payments) to the extent a specified
interest rate exceeds (in the case of a cap) or is less than (in the case of a
floor) a specified level over a specified period of time or at specified dates.
The purchaser of an interest rate collar, upon payment of a fee, has the right
to receive payments (and the seller of the collar is obligated to make payments)
to the extent that a specified interest rate falls outside an agreed upon range
over a specified period of time or at specified dates.

                                      23

<PAGE>

      Currency, index and equity swaps, caps, floors and collars:  Currency,
index, and equity swaps, caps, floors, and collars are similar to those for
interest rates described in the two preceding paragraphs above, except that,
rather than being determined by variations in specified interest rates, the
obligations of the parties are determined by variations in a specified currency,
interest rate index, or equity index, as the case may be.

     Risks and purposes of these other derivatives:  The amount of a Fund's
potential gain or loss on any swap transaction is not subject to any fixed
limit.  Nor is there any fixed limit on the Fund's potential loss if it sells a
cap, floor or collar.  If a Fund buys a cap, floor or collar, however, the
Fund's potential loss is limited to the amount of the fee that it has paid.

     Swaps, caps, floors and collars tend to be more volatile than many other
types of investments.  Nevertheless, a Fund will use these techniques only as a
risk management tool and not for purposes of leveraging the Fund's market
exposure or its exposure to changing interest rates, security values or currency
values.  Rather, a Fund will use these transactions only to preserve a return or
spread on a particular investment or portion of its investments, to protect
against currency fluctuations, as a duration management technique, to protect
against any increase in the price of securities the Fund anticipates purchasing
at a later date, or to gain exposure to certain markets in the most economical
way possible.  Nor will a Fund sell interest rate caps, floors or collars if it
does not own securities providing the interest that the Fund may be required to
pay under such derivative instruments.  Finally, of course, a Fund may use these
derivative instruments only in ways that are consistent with its investment
objective.

     The use of swaps, caps, floors and collars involves investment techniques
and risks different from those associated with other portfolio security
transactions.  If the subadviser is incorrect in its forecasts of market values,
interest rates, currency rates and other applicable factors, the investment
performance of a Fund will be less favorable than if these techniques had not
been used.

     These instruments are typically not traded on exchanges.  Accordingly,
there is a heightened risk that the other party to certain of these instruments
will not perform its obligations to the Fund.  None of the Funds will enter into
any swap, cap, floor, or collar, unless the other party to the transaction is
deemed creditworthy by the subadviser.

     There also is a risk that a Fund may be unable to enter into offsetting
positions to terminate its exposure or liquidate its investment under certain of
these instruments when it wishes to do so.  Such occurrences could result in
losses to the Fund.  In recent years, the swap market has become relatively
liquid.  Caps, floors and collars are more recent innovations for which
standardized documentation has not yet been fully developed and, for that
reason, they are less liquid than swaps.

     The liquidity of swaps, caps, floors and collars will be determined by the
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
instrument (including any demand or tender features) and (5) the nature of the
marketplace for trades (including the ability to assign or offset a Fund's
rights and obligations relating to the investment).  Such determinations will
govern whether the instrument will be deemed within the Fund's 15% restriction
on investments in securities that are not readily marketable.

     Segregation requirements for these derivatives:  Each Fund will maintain
cash or liquid high grade debt securities in a segregated account with its
custodian in an amount sufficient at all times to cover its current obligations
under swaps, caps, floors and collars.  If a Fund 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 Fund's accrued obligations under the swap agreement
over the accrued amount the Fund is entitled to receive under the agreement.  If
a Fund enters into a swap agreement on other than a net basis, or sells a cap,
floor or collar, it will segregate assets with a daily value at least equal to
the full amount of the Fund's accrued obligations under the agreement.

                                      24

22.  Investing in Other Investment Companies

     Each Fund may invest up to 10% of its total assets in shares of other
investment companies investing exclusively in securities in which that Fund may
otherwise invest.  As a shareholder in an investment company, a Fund would bear
its ratable share of that investment company's expenses, including advisory and
administration fees, except as specifically stated otherwise in the paragraphs
that follow.

     Using other investment companies to gain exposure to certain foreign
securities:  Because of restrictions on direct investment by U.S. entities in
certain countries, other investment companies may provide the most practical (or
only way) for a Fund to invest in certain markets.  Such investments may involve
the payment of substantial premiums above the net asset value of those
investment companies' portfolio securities and are subject to limitations under
the Investment Company Act of 1940.  A Fund also may incur tax liability to the
extent it invests in the stock of a foreign issuer that is a "passive foreign
investment company," regardless of whether such "passive foreign investment
company" makes distributions to the Fund.

     The Emerging Markets Equity Fund is the most likely to make significant
investments in other investment companies to gain exposure to foreign
securities; and John Hancock and the subadviser have agreed to waive their own
management fees with respect to the portion of that Fund's assets invested in
other open-end (but not closed-end) investment companies.  (An "open end"
company is one whose shares are freely redeemable.  A "closed end" company is
one whose shares can generally be disposed of only in market transactions, as
opposed to redemptions.)

     The International Equity Index Fund is likely to invest in closed-end
investment companies known as "country funds" or passive foreign investment
companies.  The International Equity Fund may also purchase shares of investment
companies investing primarily in foreign securities, including country funds.

     The Large Cap Value CORE and International Equity Funds may invest in World
Equity Benchmark Shares ("WEBS") and other investment company securities that
represent a similar interest in securities included in a foreign securities
index.  (These securities are similar in structure to the SPDR's discussed
below.)

     Investing in Standard & Poor's Depository Receipts (SPDR's):  The Equity
Index, Large Cap Value CORE, and Small/Mid Cap CORE Funds may, consistent with
their investment objectives, purchase Standard & Poor's Depository Receipts
("SPDRs").  SPDRs are American Stock Exchange-traded securities that represent
ownership in the SPDR Trust, a trust which has been established to accumulate
and hold a portfolio of common stocks that is intended to track the price
performance and dividend yield of the S&P 500.  This trust is a regulated
investment company that is sponsored by a subsidiary of the American Stock
Exchange.  SPDRs may be used for several reasons, including but not limited to:
facilitating the handling of cash flows or trading, or reducing transaction
costs.

     Investing in money market fund shares:  A  Fund may also invest in money
market funds managed by its subadviser in reliance upon an exemptive order
received by its subadviser from the SEC.  Such exemptive orders may permit funds
managed by the subadviser to invest in money market funds managed by it, to an
extent in excess of amounts otherwise permitted by the Investment Company Act.
The subadviser to the Mid Cap Growth Fund will remit the fees it receives from
money market funds it manages, to the extent such fees are based on the Mid Cap
Growth Fund's assets, to the Mid Cap Growth Fund.  Nor are the Large Cap Value
and International Opportunities Funds charged any investment management fees for
investments in money market funds managed by their subadvisers.

23.  Purchasing "When Issued" Securities and Forward Commitments

     All Funds (other than the Growth & Income and Money Market Funds) may
purchase securities on a when issued or delayed delivery basis.  When such
transactions are negotiated, the price of such securities is fixed at the time
of commitment, but delivery and payment for the securities may take place a
month or more after the date of the commitment to purchase.  The securities so
purchased are subject to market fluctuations, and no interest accrues to the
purchaser during this period.

                                      25
<PAGE>

     In addition, these Funds may make contracts to purchase securities for a
fixed price at a future date beyond customary settlement time ("forward
commitments"), because new issues of securities are typically offered to
investors on that basis.  Forward commitments involve a risk of loss if the
value of the security to be purchased declines prior to the settlement date.
This risk is in addition to the risk of decline in value of the Fund's other
assets.  Although a Fund will enter into such contracts with the intention of
acquiring the securities, the Fund may dispose of a commitment prior to
settlement if its subadviser deems it appropriate to do so.

     Asset segregation requirement for these transactions.  Each Fund will
maintain in a segregated account with its custodian cash or liquid high grade
debt securities that at all times equal the amount of its when issued and
forward commitments.

24.  Short-Term Trading

     All Funds can use short-term trading of securities as a means of managing
their portfolios to achieve their investment objectives.  As used herein,
"short-term trading" means the purchase and subsequent sale of a security after
it has been held for a relatively brief period of time, in some instances for
less than three months.  A Fund may engage in short-term trading to the extent
that the subadviser believes the transactions, net of costs (including
commissions, if any), will benefit the Fund.  Generally speaking, short-term
trading can be expected to generate expenses for a Fund that would not be
incurred by a Fund that did not engage in that practice.

25.  Entering Into Repurchase Agreements

     All of the Funds may enter into repurchase agreements.

     A repurchase agreement is a contract under which a Fund would acquire a
security for a relatively short period (e.g., 7 days), subject to the seller's
obligation to repurchase the security at a fixed time and price (representing
the Fund's cost plus interest).  Repurchase agreements will be entered into only
with member banks of the Federal Reserve System and with "primary dealers" in
U.S. Government securities.

     The Managed, Aggressive Balanced, Growth & Income, Large Cap Growth, Real
Estate Equity, Active Bond and Money Market Funds may not invest in repurchase
agreements maturing in more than 7 days.  No other Fund will invest in
repurchase agreements maturing in more than 7 days if that investment, together
with any other investments deemed "illiquid," would exceed 15% of the Fund's net
assets.

     Each Fund has a procedure providing that the securities serving as
collateral for each repurchase agreement must be delivered to the Fund's
custodian or sub-custodian, either physically or in book-entry form, and that
the collateral must be marked-to-market daily to ensure that each repurchase
agreement is fully "collateralized" at all times.  In the event of a bankruptcy
or other default by a seller of a repurchase agreement, however, the Fund could
experience delays in liquidating the underlying securities and could experience
losses (including the possible decline in the value of the underlying securities
during the period while the Fund seeks to enforce its rights thereto, possible
subnormal levels of income and lack of access to income during this period, and
expenses of enforcing its rights).

26.  Participating in Joint Trading Accounts

     John Hancock has established a "joint trading account" that all Funds, in
the discretion of their subadvisers, can use to invest relatively small amounts
of cash on a more favorable basis than they could do individually.  John Hancock
is responsible for investing the aggregate cash balances in the joint trading
account into one or more repurchase agreements, as described in Section 25.
above, or in other money market instruments.  The joint trading account was
established pursuant to an order of the SEC and the following Funds regularly
participate in it: the Managed, Aggressive Balanced, Growth & Income, Large Cap
Growth, Large/Mid Cap Value, Small/Mid Cap Growth, Real Estate Equity, Small Cap
Value, International Equity Index, High Yield Bond and Money Market Funds.

     Each Fund is also free to participate in any similar joint trading account
that their subadviser operates for mutual fund assets managed by it.  These
other joint trading accounts would be operated pursuant to their own SEC

                                      26
<PAGE>

exemptive orders, and the following Funds currently participate in such other
joint trading accounts:  the Large Cap Value CORE, Mid Cap Growth, Small/Mid Cap
CORE, Small/Mid Cap Growth, Small Cap Growth, International Equity, and Active
Bond Funds.

     In each case, the subadviser that operates one of these joint trading
accounts is responsible for ensuring that all repurchase agreements acquired
through these accounts are at all times fully collateralized.

27.  Lending of Fund Securities

     In order to generate additional income, all Funds may, and most do, lend
securities from their portfolios to brokers, dealers and financial institutions
such as banks and trust companies.  Such loans will be secured by collateral
consisting of cash or U.S. Government securities, which will be maintained in an
amount equal to at least 100% of the current market value of the loaned
securities.  During the period of the loan, the Fund receives the income (if
any) on the loaned securities, as well as additional compensation for making the
loan.  Cash collateral may be invested in short-term securities, which will
increase the current income of the Fund. Such loans will not be for more than 60
days and will be terminable by the Fund at any time.  The Fund will have the
right to regain record ownership of loaned securities in order to exercise
rights of a holder thereof including receiving interest or other distributions
or exercising voting rights.  The Fund may pay reasonable fees to persons
unaffiliated with the Fund for services in arranging such loans.

     Lending of portfolio securities involves a risk of failure by the borrower
to return the loaned securities, in which event the Fund may incur a loss.
However, most of the Funds' loans of securities are pursuant to an arrangement
with State Street Bank & Trust Company, the Trust's primary custodian.  Under
these arrangements, State Street Bank & Trust Company guarantees the Trust
against any loss or damages that any Fund incurs as a result of the borrower
failing to return the Fund's securities in accordance with the terms of the
loan.  No Fund will lend portfolio securities having a total value in excess of
33 1/3% of its total assets.

28.  Using Reverse Repurchase Agreements and Mortgage "Dollar Rolls"

     The Short-Term Bond and Money Market Funds may enter into reverse
repurchase agreements to facilitate portfolio liquidity, a practice common in
the mutual fund industry, or for arbitrage transactions (discussed below).  In a
reverse repurchase agreement, the Fund sells a security and enters into an
agreement to repurchase the security at a specified future date, but at a lower
price.  The Fund generally retains the right to interest and principal payments
on the security, as well as use of the proceeds while the repurchase agreement
is outstanding.

     The Managed, Aggressive Balanced, Short-Term Bond, Bond Index, Active Bond,
and Global Bond Funds may enter into mortgage dollar rolls, in which the Fund
sells mortgage-backed securities for delivery in the current month and
simultaneously contracts to purchase substantially similar securities at a
specified future date and price.  While the Fund foregoes principal and interest
paid on the mortgage-backed securities during the "roll" period, the Fund is
compensated by the difference between the current sale price and the lower price
for the future purchase as well as by any return earned on the proceeds of the
initial sale.

     The mortgage dollar rolls and reverse repurchase agreements entered into by
a Fund may be used as arbitrage transactions in which the Fund will maintain an
offsetting position in investment-grade debt obligations or repurchase
agreements that mature on or before the settlement date of the related mortgage
dollar roll or reverse repurchase agreement.  Since the Fund will receive
interest on the securities or repurchase agreements in which it invests the
transaction proceeds, such transactions could be considered to involve leverage.
However, since such securities or repurchase agreements will be high quality and
will mature on or before the settlement date of the mortgage dollar roll or
reverse repurchase agreement, the Trust does not believe that such arbitrage
transactions present the risks to the Fund that are associated with other types
of leverage.

     Asset segregation requirements for reverse repurchase agreements and
mortgage dollar rolls:  Each Fund will set aside in a segregated account with
its custodian liquid assets that at all times are at least equal to its
obligations under outstanding reverse repurchase agreements and mortgage dollar
rolls it has entered into.

                                      27

29.  Investing in Rule 144A and Illiquid Securities

     All Funds, other than the Growth & Income, Large Cap Growth and Real Estate
Equity Funds, may purchase unregistered securities that are eligible for resale
to "qualified institutional buyers" pursuant to Rule 144A under the Securities
Act of 1933.  Case-by-case determinations are made whether each issue of Rule
144A securities owned by the Fund is an illiquid security.

     If illiquid, a Rule 144A security may not be purchased by the Money Market
Fund.  Nor may the Money Market Fund purchase any other investments that are
deemed to be illiquid, if the total of all its illiquid assets would be more
than 10% of its net assets.  Each Fund other than the Money Market Fund,
however, may purchase illiquid Rule 144A securities, or other illiquid assets
if, and only if, the total of all the Fund's illiquid assets would not thereby
be made to exceed 15% of the Fund's net assets.


                 THE FUNDS' FUNDAMENTAL INVESTMENT RESTRICTIONS

     The Funds' investment objectives and strategies may, in general, be changed
without the approval of shareholders.

In a few cases, however, the Investment Company Act requires such approval.  In
addition, the Trust has adopted as "fundamental" the below-listed restrictions
relating to the investment of each Fund's assets.  That these restrictions are
"fundamental" policies means that they may not be changed for any Fund without
the approval of a majority of the outstanding voting shares of each affected
Fund.  (The term "majority of the outstanding voting shares" means the lesser of
(1) 67% of the shares represented at a meeting at which more than 50% of the
outstanding shares are represented or (2) more than 50% of the outstanding
shares.)

     To the extent the Trust's prospectus or this Statement of Additional
Information anywhere sets forth investment restrictions more restrictive than
the fundamental restrictions described below, the more restrictive limitation
controls; but any such more restrictive limitation may be changed without any
shareholder approval, subject to the below fundamental restrictions.

     As a matter of fundamental policy, no Fund will:

     (1) Purchase real estate or any interest therein, except through the
purchase of corporate or certain government securities (including securities
secured by a mortgage or a leasehold interest or other interest in real estate).
A security issued by a real estate or mortgage investment trust or an interest
in a pool of real estate mortgage loans is not treated as an interest in real
estate.  Investments of the type permitted in the Real Estate Equity Fund are
not deemed interests in real estate for the purposes of this restriction.

     (2) Make loans, other than through the acquisition of obligations in which
the Fund may invest consistent with its objective and investment policies,
except that each Fund may lend portfolio securities not having a value in excess
of 33 1/3% of the Fund's total assets.

     (3) Invest in commodities or in commodity contracts or in puts, calls or a
combination of both, except that

         (A) the Managed, Aggressive Balanced, Equity Index, Large Cap Value,
     Large Cap Growth, Large Cap Value CORE, Large Cap Aggressive Growth,
     Large/Mid Cap Value, Mid Cap Value, Mid Cap Growth, Fundamental Mid Cap
     Growth, Mid Cap Blend, Small/Mid Cap Value, Small/Mid Cap Growth, Small/Mid
     Cap CORE, Small Cap Value, Small Cap Growth, Global Equity, Global
     Balanced, International Equity Index, International Equity, International
     Opportunities, Emerging Markets Equity, Short-Term Bond, Bond Index, Global
     Bond, and High Yield Bond Funds may

             (i)  write call options on, and purchase put options covered by,
         securities held by them and purchase and sell options to close out
         positions thus established, provided that no such

                                      28
<PAGE>

         covered call or put option position will be established in the Large
         Cap Growth Fund if more than one-third of the Fund's total assets would
         immediately thereafter be subject to such call and put options,

             (ii)   purchase options on stock indexes and write such options to
         close out positions previously established, and

             (iii)  enter into financial futures contracts or purchase options
         on such contracts, and effect offsetting transactions to close out such
         positions previously established; provided that, (a) as to the Large
         Cap Value, Large Cap Growth, Mid Cap Value, and Small Cap Value Funds,
         no position in financial futures, options thereon or options on
         securities indexes will be established if, immediately thereafter, the
         then-current aggregate value of all securities owned or to be acquired
         by the Fund which are hedged by such instruments exceeds one-third of
         the value of its total assets and (b) as to such Funds, and as to the
         Equity Index and International Opportunities Funds, no futures position
         or position in options on futures will be established if, immediately
         thereafter, the total of the initial margin deposits required by
         commodities exchanges with respect to all open futures positions at the
         time such positions were established, plus the sum of the premiums paid
         for all unexpired options on futures contracts would exceed 5% of the
         Fund's total assets;

         (B) with respect to the Managed, Aggressive Balanced, Equity Index,
     Large Cap Value, Large Cap Value CORE, Large Cap Aggressive Growth,
     Large/Mid Cap Value, Mid Cap Value, Mid Cap Growth, Fundamental Mid Cap
     Growth, Mid Cap Blend, Small/Mid Cap Value, Small/Mid Cap Growth, Small/Mid
     Cap CORE, Small Cap Value, Small Cap Growth, Global Equity, Global
     Balanced, International Equity Index, International Equity, International
     Opportunities, Emerging Markets Equity, Short-Term Bond, Bond Index, Active
     Bond, Global Bond, and High Yield Bond Funds, forward foreign exchange
     contracts, forward commitments, and when issued securities are not deemed
     to be commodities or commodity contracts or puts or calls for the purposes
     of this restriction;

         (C) the Managed, Aggressive Balanced, Mid Cap Growth, Large Cap Value
     CORE, Large Cap Aggressive Growth, Large/Mid Cap Value, Small/Mid Cap
     Growth, Small/Mid Cap CORE, Small Cap Growth, Global Equity, Global
     Balanced, International Equity Index, International Equity, Emerging
     Markets Equity, Short-Term Bond, Bond Index, Global Bond, and High Yield
     Bond Funds may, in addition to the activities permitted in (A) and (B)
     above,

             (i)    write put and call options on securities and market indexes,
         if such positions are covered by other securities or outstanding put
         and call positions of the Fund, and purchase put and call options to
         close out any positions thus established, and

             (ii)   enter into futures contracts on securities or market
         indexes, or purchase or write put or call options on such futures
         contracts, for hedging or speculative (non-hedging) purposes, and enter
         into offsetting transactions to close out any positions thus
         established; provided that none of these Funds may purchase, sell or
         write such futures or options other than for bona fide hedging purposes
         if immediately thereafter the Fund's margin deposits on such non-
         hedging positions, plus the amount of premiums paid for outstanding
         options on futures contracts that are not for bona fide hedging
         purposes (less any amount by which any such option is "in the money" at
         the time of purchase) exceeds 5% of the market value of the Fund's net
         assets;

         (D) the Active Bond Fund may enter into futures contracts and purchase
     or write options thereon to the same extent as is permitted in (C), above,
     with respect to the Funds listed therein; and

         (E) the Managed, Aggressive Balanced, Equity Index, Large Cap Value,
     Large Cap Value CORE, Large Cap Aggressive Growth, Large/Mid Cap Value, Mid
     Cap Value, Mid Cap Growth, Fundamental Growth, Mid Cap Blend, Small/Mid Cap
     Value, Small/Mid Cap CORE, Small Cap Value, Small Cap Growth, Global
     Equity, Global Balanced, International Equity Index, International Equity,
     International Opportunities, Emerging Markets Equity, Global Bond, and High
     Yield Bond Funds may

                                      29
<PAGE>

     purchase or write put or call options on foreign currencies, may purchase
     put or call options on securities, and may enter into closing transactions
     with respect to any of such options.

     (4) Engage in the underwriting of securities of other issuers, except to
the extent the Fund may be deemed an underwriter in selling as part of an
offering registered under the Securities Act of 1933 securities which it has
acquired.

     (5) Borrow money, except from banks as a temporary measure where such
borrowings would not exceed 5% of the market value of total assets of the Fund
as of the time each such borrowing is made, or 10% as to the Aggressive
Balanced, Large Cap Value CORE, Large Cap Aggressive Growth, Large/Mid Cap
Value, Fundamental Growth, Mid Cap Blend, Small/Mid Cap Value, Small/Mid Cap
CORE, Global Equity, International Equity Index, International Equity, Emerging
Markets Equity, Bond Index and High Yield Bond Funds, subject to a non-
fundamental policy that none of these Funds will make additional investments at
any time when such borrowings plus any amounts payable by the Fund under reverse
repurchase agreements exceed 5% of that Fund's total assets.

     (6) Except as set forth in the following sentence, neither the Managed and
Active Bond Funds, nor the Growth & Income, Large Cap Growth, Real Estate
Equity, or Money Market Funds may purchase securities which are subject to legal
or contractual delays in or restrictions on resale.  The Managed and Active Bond
Funds may, however, purchase restricted securities, including those eligible for
resale to "qualified institutional buyers" pursuant to Rule 144A under the
Securities Act of 1933, subject to a non fundamental restriction limiting all
illiquid securities held by each Fund to not more than 15% of the Trust's net
assets.

     (7) Purchase securities on margin, except for short-term credits as may be
necessary for the clearance of purchases or sales of securities, or effect a
short sale of any security.  Neither the use of futures contracts as permitted
by restriction (3), above nor the use of option contracts as permitted by
restriction (3) above, shall be deemed to be the purchase of a security on
margin.

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

     (9) Unless received as a dividend or as a result of an offer of exchange
approved by the Securities and Exchange Commission ("SEC") or of a plan of
reorganization, purchase or otherwise acquire any security issued by an
investment company if the Fund would immediately thereafter own (a) more than 3%
of the outstanding voting stock of the investment company, (b) securities of the
investment company having an aggregate value in excess of 5% of the Fund's total
assets, (c) securities of investment companies having an aggregate value in
excess of 10% of the Fund's total assets, or (d) together with investment
companies having the same investment adviser as the Fund (and companies
controlled by such investment companies), more than 10% of the outstanding
voting stock of any registered closed-end investment company.  A real estate or
mortgage investment trust is not considered an investment company.  This
restriction (9) does not apply to the Aggressive Balanced, Equity Index, Large
Cap Value, Large Cap Value CORE, Large Cap Aggressive Growth, Large/Mid Cap
Value, Mid Cap Value, Mid Cap Growth, Fundamental Growth, Mid Cap Blend,
Small/Mid Cap Value, Small/Mid Cap CORE, Small Cap Value, Small Cap Growth,
Global Equity, International Equity, Global Balanced, International
Opportunities, Emerging Markets Equity, Bond Index, Global Bond, or High Yield
Bond Funds.

     (10) Purchase securities of any issuer, if (a) with respect to 75% of the
market value of its total assets, more than 5% of the Fund's total assets taken
at market value would at the time be invested in the securities of such issuer,
unless such issuer is the United States Government or its agency or
instrumentality, or (b) such purchase would result in more than 10% of the
outstanding voting securities of such issuer being held by the Fund.  This
restriction (10) does not apply to the Large Cap Aggressive Growth, Mid Cap
Growth or Global Balanced Funds.

     (11) Issue senior securities.  For the purposes of this restriction, the
following shall not be deemed to be the issuance of a senior security:  the use
of futures contracts as permitted by restriction (3), above; the use of option
contracts as permitted by restriction (3), above; and the use of foreign
currency contracts.

Global Equity, Global Balanced, International Equity Index, International
Equity, International Opportunities, Emerging Markets Equity, Short-Term Bond,
Bond Index, Active Bond, Global Bond, and High Yield Bond Funds will not
purchase the securities of issuers conducting their principal business activity
in the same industry if, immediately after such purchase, the value of the
Trust's investments in such industry would exceed 25% of its total assets taken
at market value.  For the purpose of this restriction, telephone, water, gas and
electric public utilities are each regarded as separate industries, and wholly-
owned finance companies are considered to be in the industry of their parents if
their activities are primarily related to financing the activities of their
parent.  In conformity with its understanding of current interpretations of the
Investment Company Act by the staff of the SEC, the Trust, as a non-fundamental
policy, interprets this limitation not to apply to securities issued by the
Federal government, or state and local governments within the U.S., or political
subdivisions thereof; but this exception does not apply to securities of foreign
government entities.  If these interpretations change, however, the Trust may
modify its practices to conform to such changes.

     For purposes of any restrictions or limitation to which the Trust is
subject, no Fund, by entering into any futures contract or acquiring or writing
any option thereon or on any security or market index, shall be deemed

     (1) to have acquired or invested in any securities of any exchange or
clearing corporation for any such instrument or

     (2) to have acquired or invested in any debt obligations or in any stocks
comprising indexes on which such instrument is based, but which the Fund does
not hold directly in its portfolio.

* Ms. Van Leer and Mr. Lee are the only Trustees who are "interested persons" as
defined in the Investment Company Act. They also constitute the Trust's
Executive Committee. The Executive Committee may from time to time be delegated
power to act on behalf of the Board of Trustees, except with repect to
declarations of dividends or distributions, recommendations to the shareholders
on actions requiring shareholder approval, changes to the Trust's bylaws, or
mergers or share exchanges which do not require shareholder approval.

     Certain members of the Trust's Board of Trustees may own either variable
annuity contracts or variable life insurance policies that are supported by one
of the Separate Accounts and, in that sense, have an interest in shares of the
Trust.

The combined interest of all the Trust's officers and Trustees, however, does
not aggregate as much as 1% of any Fund's net assets.

     Compensation paid by the Trust to its current disinterested Trustees during
1999 was as follows:

                    Ms. Cook              $46,600.00
                    Ms. Kessler           $30,550.00
                    Mr. Verdonk           $30,250.00

The Trust paid no compensation to any other officer or Trustee.

of other service providers to the Trust. John Hancock also provides the Trust
with office space, supplies and other facilities required for the business of

     Under the investment advisory agreements, for any fiscal year in which the
normal operating costs and expenses of any Fund, exclusive of the investment
advisory fee, interest, brokerage commissions, taxes and extraordinary expenses
outside the control of John Hancock exceed 0.10% (.25% prior to April 23, 1999)
of that Fund's average daily net assets, John Hancock will reimburse that Fund
in an amount equal to such excess. These reimbursements have been as follows for
the past three years (rounded to the nearest $1,000):

                    ARRANGEMENTS WITH OTHER SERVICE PROVIDERS
                                  TO THE TRUST

Underwriting and Indemnity Agreement

     Pursuant to an Underwriting and Indemnity Agreement, Signator Investors,
Inc. ("Signator") serves as the Trust's principal underwriter, and John Hancock
provides certain indemnities to the Trust and its Trustees. Neither Signator nor
John Hancock receives any additional compensation from the Trust for the
services and indemnities they provide pursuant to the Underwriting and Indemnity
Agreement. The offering of the Trust's shares through Signator is a continuous
offering on a "best efforts" basis. Signator is a wholly-owned subsidiary of
John Hancock and is located at 197 Clarendon Street, Boston, MA 02117.

Custody of the Trust's Assets

     State Street Bank and Trust Company ("State Street Bank") is the primary
custodian of the assets of all Funds. State Street Bank's principal business
address is 225 Franklin Street, Boston MA 02110. The primary custodian's duties
include safeguarding and controlling the Trust's cash and investments, handling
the receipt and delivery of securities, and collecting interest and dividends on
the Trust's investments. Fund securities purchased in the United States are
maintained in the custody of State Street Bank, although such securities may be
deposited in the book-entry system of the Federal Reserve System, with
Depository Trust Company, or with other qualified domestic book- entry systems
or depositories. Also, pursuant to its agreement with the Trust, State Street
Bank

                                      40
<PAGE>

provides certain accounting and recordkeeping services to the Trust and
generally values the Trust's assets by computing each Fund's net asset value
each day. The Trust compensates State Street Bank for these functions through
the payment ofan annual custody asset fee of .01% of the total net assets of the
Trust, allocated to each Fund based on the percentage of that Fund's total net
asssets to the total net asets of the Trust; miscellaneous trasaction charges
ranging from $7.00 to $25.00; global asset and transaction fees that vary by the
country in which a Fund's assets are held or traded; a monthly accounting fee
charge that is allocated to each Fund based on the percentage of that Fund's
total net assets to the total net assets of the Trust; valuation and monthly
quote charge; special service fees for activities of a non-recurring nature; and
reimbursement of specified out-of-pocket expenses.

     Foreign securities are generally held through subcustodian banks and
depositories around the world with whom State Street Bank has relationships. In
some cases, Funds whose securities are held in this manner may be exposed to
greater risks of loss. This is because the soundness of such foreign entities,
as well as foreign regulatory practices and procedures, may provide less
protection to security holders than is available in the U.S.

     In certain circumstances, brokers may have access to assets that a Fund
posts as "margin" in connection with futures and options transactions. In the
event of a broker's insolvency or bankruptcy, a Fund could experience a delay or
incur costs in recovering such assets or might recover less than the full amount
due. Also the value of such assets could decline by the time the Trust could
effect such recovery.

     If on any day a Fund experiences net realized or unrealized gains with
respect to financial futures contracts held through a given broker, it will be
entitled immediately to receive from the broker the net amount of such gains.
The Trust will request payment of such amounts promptly after notification by
the broker that such amounts are due. Thereupon, these assets will be deposited
in the Trust's general or segregated account with its primary custodian, as
appropriate.

Subadministration  Agreement With State Street Bank

     Pursuant to a subadministration agreement, with the Trust, State Street
Bank also provides assistance to John Hancock and the subadvisers in computing
total return information for the Trust and in monitoring each Fund's compliance
with the Fund's investment objectives and restrictions, as well as compliance
with certain other applicable legal requirements, . The Trust compensates State
Street Bank for these services through payment of an annual fee that accrues
daily and is billed monthly in arrears. The annual fee is based on the average
net assets of the Trust and is 0.012% of the first $1 billion of average net
assets, 0.0075% of the next $1 of average net assets, and 0.0025% of average net
assets after that. Each Fund is allocated the greater of a minimum monthly Fund
fee or the basis point annual fee, based on the pro- rata total net asset value
of that Fund. The minimum monthly Fund fee is phased-in for new Funds at the
rate of 1/12 in month one, 2/12th in month two, increasing incrementally per
month until the full monthly minimum is in effect in month 12 ($1,333).

Independent Auditors

     Ernst & Young LLP, 200 Clarendon Street, Boston, Massachusetts, are the
independent auditors of the Trust. Ernst & Young audits the financial statements
of the Trust, prepares the Trust's tax returns, and renders other advice to the
Trust concerning accounting and tax matters. Ernst & Young also meets
periodically with the Trust's Board and with the Audit Committee of the Board to
discuss matters within the scope of Ernst & Young's activities with respect to
the Trust.

                PORTFOLIO TRANSACTIONS AND BROKERAGE ALLOCATION

     The Funds pay brokers' commissions, transfer taxes, and other fees relating
to their specific portfolio transactions. (Investments in debt securities are,
however, generally traded on a "net" basis through issuers or dealers acting for
their own account as principals and not as brokers. Therefore, no brokerage
commissions are payable on most such transactions, although the price to the
Trust usually reflects a dealer "spread" or "mark- up.")

Amounts of Brokerage Paid

     Brokerage commissions paid by the Funds were as follows for the past three
years:

                                    1999            1998            1997

How Brokers and Dealers are Selected

     Orders for the purchase and sale of Fund portfolio investments are placed
by John Hancock with respect to the Money Market Fund and by the respective
subadvisers to the other Funds. All of these subadvisers place orders in such
manner as, in their opinion, will offer the best overall price and execution of
each transaction. In seeking the best price and execution for equity securities
traded only in the over-the-counter market, they normally deal directly with the
principal market-makers.

     The subadvisers are governed in the selection of brokers and dealers and
the negotiation of brokerage commission rates (or the payment of net prices in
the case of debt securities) by the reliability and quality of the broker's or
dealer's services. Although some weight is given to the availability and value
of research and statistical assistance (discussed immediately below) furnished
by the broker or dealer to the subadviser, it is not always possible to place a
dollar value on such information and services. Because it is only supplementary
to the

                                      42
<PAGE>

subadvisers' own research efforts, the receipt of research information and
statistical assistance is not expected to reduce their expenses measurably.

Research and Statistical Services Furnished by Brokers and Dealers

     Research and statistical assistance typically furnished by brokers or
dealers includes analysts' reports on companies and industries, market
forecasts, and economic analyses. Brokers or dealers may also provide reports on
pertinent federal and state legislative developments and changes in accounting
practices; direct access by telephone or meetings with leading research analysts
throughout the financial community, corporate management personnel, industry
experts, leading economists and government officials; comparative performance
and evaluation and technical performance measurement services; portfolio
optimization software; availability of economic advice; quotation services; and
services from recognized experts on investment matters of particular interest to
the subadviser. In addition, the foregoing services may comprise the use of or
be delivered by computer systems whose software and hardware components may be
provided to the subadviser as part of the services. In any case in which the
foregoing systems can be used for both research and non-research purposes, the
subadviser makes an appropriate allocation of those uses and will permit brokers
and dealers to provide only the portion of the systems to be used for research
services.

     Research and statistical services furnished by brokers and dealers handling
the Funds' transactions may be used by the subadvisers for the benefit of all of
the accounts managed by them and not all of such research and statistical
services may be used by the subadvisers in connection with the Funds.

Relationship Between Brokerage Commissions and Research and Statistical Services
Furnished by Brokers and Dealers

     Except as to the Global Balanced Fund, the subadvisers or the Funds will
not at any time make a commitment pursuant to an agreement with a broker because
of research services provided. Nor, except as set forth below, will John Hancock
or the subadvisers direct brokerage upon any prescribed basis to a broker
because of research services provided.The subadviser for each of the Small Cap
Value, Small/Mid Cap Value, Mid Cap Growth, and Mid Cap Value Funds may have an
internal procedure for allocating transactions, in a manner consistent with its
execution policy, to brokers that it has identified as providing superior
executions, research, or research related products or services which benefit its
advisory clients, including the Fund. In certain cases, the subadviser of the
Global Balanced Fund directs securities transactions for that Fund to particular
brokers, in recognition of research services the broker has provided, pursuant
to an understanding or agreement with the broker or pursuant to the subadviser's
own internal allocation procedures.

     Evaluations of the overall reasonableness of any broker's commissions are
made by the subadvisers' traders for the Funds on the basis of their experience
and judgment. To the extent permitted by Section 28(e) of the Securities
Exchange Act of 1934, such traders are authorized to pay a brokerage commission
on a particular transaction in excess of what another broker might have charged
in recognition of the value of the broker's brokerage or research services. Such
authority is generally expected to be used very infrequently. The Mid Cap
Growth, Small/Mid Cap Value, Mid Cap Value, and Global Balanced Funds, however,
may be more likely to use such authority.

Brokerage Transactions in Foreign Markets

     Brokerage transactions in securities of companies domiciled in countries
other than the United States are anticipated to be normally conducted on the
stock exchanges or other markets of those countries in which the particular
security is traded. Fixed commissions on foreign stock exchange transactions are
generally higher than negotiated commissions available in the United States.
Moreover, there is generally less government supervision and regulation of
foreign stock exchanges and broker-dealers than in the United States. Settlement
periods in non-U.S. markets may differ from the normal settlement period in the
United States.

                                      43
<PAGE>

Simultaneous Transactions with Other Accounts

     The subadvisers also perform investment advisory services for a number of
other accounts and clients, none of which is given preference over the Trust in
allocating investment opportunities. When opportunities occur which are
consistent with the investment objective of more than one account, it is the
policy of each subadviser to avoid favoring any one account over another.
Accordingly, investment opportunities in such cases are allocated in a manner
deemed equitable by the subadvisers to the particular accounts involved. The
allocation may be based, for example, on such factors as the accounts'r
respective investment objectives and then current investment and cash positions.
Subject to these requirements, Trust orders may be combined with orders of other
accounts or clients advised by any of the subadvisers at prices which are
approximately averaged.

Use of Brokers Who are Affiliated With a Subadviser

     A Fund may place portfolio transactions through certain brokers who are
affiliated with the Fund's subadviser. The Trust has implemented special
procedures governing the circumstances of these transactions. In addition to
complying with any applicable provisions of the Trust's procedures, these
transactions must comply with all applicable legal requirements, including,
where applicable, Rule 17e-1 under the Investment Company Act. Among other
things, that rule requires the commissions or other compensation paid to the
affiliated broker to be reasonable and fair compared to those in similar
transactions between unrelated parties.

     Set forth below is information about transactions by each Fund with
affiliated brokers in reliance on Rule 17e-1 for each of the past three years:

                           CODES OF PERSONAL CONDUCT

     The Funds (other than the Money Market Fund), John Hancock, and the Trust's
principal underwriter have adopted, and the Trustees have approved, codes of
conduct for their officers, directors and other personnel. Among other things
these codes regulate (although they do not absolutely prohibit) transactions by
such persons in securities of a type in which the Funds may and do invest. The
subadvisers have adopted codes of conduct that are similar to the Fund's except
that certain subadvisers may prohibit certain of their key personnel from
personal trading in certain types of securities such as initial public offerings
or private offerings.

                         FEATURES OF THE TRUST'S SHARES

     The shares of beneficial interest of the Trust currently are divided into
31 series, each corresponding to one of the Trust's 31 Funds. The Trust has the
right to establish additional series and issue additional shares without the
consent of its shareholders.

     If the holders of variable annuity contracts and variable life insurance
policies show minimal interest in any Fund, the Trust's Board of Trustees, by
majority vote, may eliminate the Fund or substitute shares of another investment
company. Any such action by the Board would be subject to compliance with any
requirements for governmental approvals or exemptions or for shareholder
approval. The holders of variable annuity contracts and variable life insurance
policies participating in any such Fund will be notified in writing of the
Trust's intention to eliminate the Fund and given 30 days to transfer amounts
from such Fund to other Funds without incurring any transaction fee. Amounts not
transferred or withdrawn would automatically be transferred, at the discretion
of the Fund's management.

     The assets received by the Trust for the issuance or sale of shares of each
Fund and all income, earnings, profits, and proceeds thereof are specifically
allocated to that Fund. They constitute the underlying assets of each Fund, are
segregated on the books of the Trust, and are to be charged with the expenses of
such Fund. Any assets which are not clearly allocable to a particular Fund or
Funds are allocated in a manner determined by the Board of Trustees. Accrued
liabilities which are not clearly allocable to one or more Funds would generally
be allocated among the Funds in proportion to their relative net assets before
adjustment for such unallocated liabilities.

     Each issued and outstanding share in a Fund is entitled to participate
equally in dividends and distributions declared with respect to such Fund and in
the net assets of such Fund upon liquidation or dissolution remaining after
satisfaction of outstanding liabilities.

     A dividend from the net investment income of the Money Market Fund will be
declared and distributed daily. Dividends from net investment income of the
other Funds will be declared and distributed monthly. The Trust will distribute
all of its net realized capital gains annually. Dividends and capital gains
distributions will normally be reinvested in additional full or fractional
shares of the Fund to which they relate and will be appropriately credited to
investment performance under the variable life insurance policies and variable
annuity contracts participating in that Fund.

     The shares of each Fund, when issued, will be fully paid and
non-assessable, and will have no preference, preemptive, exchange or similar
rights. Shares do not have cumulative voting rights.

                     SHAREHOLDER MEETINGS AND VOTING RIGHTS

     Under the Trust's Declaration of Trust, the Trust is not required to hold
an annual shareholders' meeting. Normally, for example, there will be no
shareholders meetings for the purpose of electing Trustees.

     In addition, it is expected that the Trustees generally will elect their
own successors and appoint Trustees to fill any vacancy, so long as, after
filling the vacancy, at least two-thirds of the Trustees then in office have
been elected by the shareholders.

                                      45
<PAGE>

     Notwithstanding the above if at any time less than a majority of Trustees
in office have been elected by the shareholders, the Trustees must call a
special shareholders' meeting promptly. Also the Trustees will promptly call a
meeting of shareholders for the purpose of voting upon the question of removal
of any Trustee or all of the Trustees, if requested in writing to do so by
holders of 10% or more of the outstanding shares. In this regard, whenever ten
or more shareholders who have been such for at least six months and who hold in
the aggregate either shares having a net asset value of at least $25,000 or at
least 1% of the outstanding shares, whichever is less, apply to the Trustees in
writing stating that they wish to communicate with other shareholders with a
view to obtaining signatures to a request for a shareholders' meeting, for
consideration of the removal of any or all of the Trustees and accompanied by
the material which they wish to transmit, the Trustees will within five business
days after receipt either afford to such applicants access to the Trust's
shareholder list or inform such applicants as to the approximate number of
shareholders of record, and the approximate cost of mailing the material. If the
Trustees elect the latter, the Trustees, upon written request of such
applicants, accompanied by the material to be mailed and the reasonable expenses
of mailing, shall promptly mail such material to all shareholders of record,
unless within five business days the Trustees shall mail to such applicants and
file with the SEC, together with a copy of the material to be mailed, a written
statement signed by at least a majority of the Trustees to the effect that, in
their opinion, either such material is misleading or in violation of applicable
law and specifying the basis of such opinion.

     At any shareholders' meeting, all shares of the Trust of whatever class are
entitled to one vote, and the votes of all classes are cast on an aggregate
basis, except on matters where the interests of the Funds differ. Where the
interests of the Funds differ, the voting is on a Fund-by-Fund basis. Approval
or disapproval by the shareholders in one Fund on such a matter would not
generally be a prerequisite of approval or disapproval by shareholders in
another Fund; and shareholders in a Fund not affected by a matter generally
would not be entitled to vote on that matter. Examples of matters which would
require a Fund-by-Fund vote are changes in the fundamental investment policy of
a particular Fund and approval of investment management or sub-investment
management agreements.

                      SALES AND REDEMPTIONS OF FUND SHARES

"Seed Money" Shares

     Typically, when a new Fund is added to the Trust, John Hancock (or one of
its affiliates) initially purchases a substantial amount of that Fund's shares
to provide the new fund with a reasonable asset base with which to commence
operations. For example, the most recent such contributions of "seed money" have
been as follows:

                                              "Seed Money"          Date

     John Hancock (or its affiliate) may redeem these shares (and thus withdraw
its seed money investment) at some time. However, before withdrawing any part of
their interests in any Fund, John Hancock (or its affiliate) will consider any
possible adverse impact the withdrawal might have on that Fund.

     Purchases and redemptions of seed money shares are made at the applicable
Fund's net asset value per share (with no additions or deductions for charges)
next computed after the purchase or redemption order is placed.

     Shares Sold and Redeemed In Connection With Transactions Under Variable
Annuity Contracts and Variable Life Insurance Policies

     Fund shares are sold at their net asset value as next determined after
receipt of net premiums by the Separate Account, without the addition of any
selling commission or sales load.

     Shares are redeemed at their net asset value as next determined after
receipt of net surrender requests by the Separate Account. No fee is charged on
redemption. Redemption payments will usually be paid within seven days after
receipt of the redemption request, except that the right of redemption may be
suspended or payments postponed whenever permitted by applicable law and
regulations. Redemptions are normally made in cash, but the Trust reserves the
right, at its discretion, to make full or partial payment by assignment to the
appropriate Separate Account of portfolio securities at their value used in
determining the redemption price. In such cases, the Separate Account would
incur brokerage costs should it wish to liquidate these portfolio securities.

     Trust shares are also sold and redeemed as a result of transfer requests,
loans, loan repayments, and similar Separate Account transactions, in each case
without any sales load or commission or at the net asset value per share
computed for the day as of which such Separate Account transactions are
effected.


                      COMPUTING THE FUNDS' NET ASSET VALUE

     The net asset value per share of each Fund is determined once daily, after
the declaration of dividends, if any, as of 4:00 p.m., New York City time, on
each business day the New York Stock Exchange ("Exchange") is open for regular
trading. For this purpose, however, certain derivative instruments may be valued
using prices as late as 4:15 p.m.

     The net asset value per share of each Fund is determined by adding the
value of all portfolio securities and other assets, deducting all portfolio
liabilities, and dividing by the number of outstanding shares. All Trust
expenses will be accrued daily for this purpose.

     Short-term investment with a remaining maturity of 60 days or less, and all
investments of the Money Market Fund, are valued at "amortized cost," which
approximates market value. This involves valuing a security at its cost and
thereafter assuming a constant amortization to maturity of any discount or
premium, regardless of the impact of fluctuating interest rates. While this
method provides certainty in valuation, it may result in periods during which
the value of an instrument, as determined by amortized cost, is higher or lower
than the price the Fund would receive upon the sale of the instrument.

     The Board of Trustees has established procedures designed to stabilize the
Money Market Fund's price per share, as computed for the purpose of sales and
redemptions, at $10. There can be no assurance, however, that the Fund will at
all times be able to maintain a constant $10 net asset value per share. Such
procedures include review of the Fund's holdings at such intervals as is deemed
appropriate to determine whether the Fund's net asset value, calculated by using
available market quotations, deviates from $10 per share and, if so, whether
such deviation may result in material dilution, or is otherwise unfair to
existing shareholders. In the event that it is determined that such a deviation
exists, the Board of Trustees will take such corrective action as it regards as
necessary and appropriate. Such action may cause losses or gains to be recorded
for the Fund, including decreases or increases in the Fund's net asset value per
share.

                                      47
<PAGE>

     Securities and covered all and put options that are listed on a stock
exchange are normally valued at the closing sales price. If there were no sales
during the day, they are normally valued at the last previous sale or bid price
reported, as are equity securities that are traded in the over-the-counter
market.

     Non-exchange traded debt securities (other than certain short-term
investments) are valued on the basis of valuations furnished by a pricing
service which uses electronic data processing techniques, without exclusive
reliance upon quoted prices.

     Any other security for which market quotations are not readily available,
and any other property for which valuation is not otherwise available, is valued
at fair value as determined in good faith by, or under the direction of, the
Board of Trustees.

     Financial futures contracts, options thereon and options on stock indexes
are valued at the last trade price of the day. In the absence of a trade on a
given day, the value generally is used which is established by the exchange on
which the instrument is traded.

     Trading in securities on European and Far Eastern securities exchanges and
over-the-counter markets is normally completed at various times before the close
of business on each day on which the New York Stock Exchange is open. The values
of such securities used in computing net asset value per share are normally
determined as of such times. Trading of these securities may not take place on
every New York Stock Exchange business day and may take place on days which are
not business days in New York. The Trust calculates net asset value per share as
of the close of regular trading on the New York Stock Exchange on each day on
which that exchange is open. Therefore, such calculation does not take place
contemporaneously with the determination of the prices of many of the Funds'
securities used in such calculation. If events affecting the value of such
securities occur between the time when their price is determined and the time as
of which the Fund's net asset value is calculated, such securities may be valued
at fair value by or under the direction of the Board of Trustees.


                                     TAXES

     The Trust intends that each Fund qualify as a regulated investment company
under Subchapter M of the Internal Revenue Code ("Code"). This requires that
each Fund comply with certain requirements as to the nature of its income and
amounts of dividends and other distributions it pays. Also, in order to qualify
under Subchapter M, at the end of each quarter of a Fund's taxable year, (i) at
least 50% of the market value of the Fund's assets must be represented by cash
and cash items, U.S. Government securities, securities of other regulated
investment companies, 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 of 5% of the value of the Fund's total assets;
and (ii) not more than 25% of the value of its assets may be 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 Fund controls and which are
engaged in the same, similar or related trades or businesses.

     The Trust also intends that each Fund comply with certain other
diversification requirements, promulgated under Section 817(h) of the Code.
Under these requirements, no more than 55% of the total value of the assets of
each Fund may 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 these purposes, 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 States), each U.S. Government agency
or instrumentality is treated as a separate issuer.

     Assuming the Funds qualify as regulated investment companies under
Subchapter M, they will not owe any income taxes. On the other hand, if a Fund
fails to qualify under Subchapter M, it may incur income tax liabilities, which
will negatively affect its investment performance.

     Also, qualification under Subchapter M, as well as compliance with the
Section 817(h) diversification requirements, (among other things) are necessary
to secure the tax treatment intended for holders of variable annuity

                                      48
<PAGE>

contracts and variable life insurance policies that are supported by the Trust.
Therefore, any such failure to qualify under Subchapter M or to meet the
diversification standards under Section 817(h) could have serious adverse
consequences for such investors.

     For a discussion of these and other tax implications of owning a variable
annuity contract or a variable life insurance policy for which the Fund serves
as the investment medium, please refer to the Prospectus for such contract or
policy attached at the front of this Prospectus.

     Those Funds that invest substantial amounts of their assets in foreign
securities may be able to make an election to pass through to John Hancock,
JHVLICO or IPL any taxes withheld by foreign taxing jurisdictions on foreign
source income. Such an election will result in additional taxable income and
income tax to John Hancock. The amount of additional income tax, however, may be
more than offset by credits for the foreign taxes withheld, which are also
passed through.


                       INFORMATION ABOUT FUND PERFORMANCE

How Money Market Fund Yields Are Calculated

     The Money Market Fund may advertise investment performance figures,
including its current yield and its effective yield.

     The Money Market Fund's yield is its current investment income, expressed
in annualized terms. The current yield is based on a specified
seven-calendar-day period. It is computed by (1) determining the net change
(exclusive of capital changes) in the value of a hypothetical pre-existing
account having a balance of one share at the beginning of the period, (2)
dividing the net change in account value by the value of the account at the
beginning of the base period to get the base period return, then (3) multiplying
the base period return by 52.15 (365 divided by 7). The resulting yield figure
is carried to the nearest hundredth of one percent.

     The calculations include the value of additional shares purchased with any
dividends paid on the original share and the value of dividends declared on both
the original share and any such additional shares. The capital changes excluded
from the calculation are realized capital gains and losses from the sale of
securities and unrealized appreciation and depreciation.

     Compound (effective) yield for the Fund will be computed by dividing the
seven-day annualized yield (determined as above) by 365, adding 1 to the
quotient, raising the sum to the 365th power, and subtracting 1 from the result.

     For the seven-day period ending December 31, 1999, the Money Market Fund's
current yield was 5.74%; its effective yield was 5.91%.

     The Fund's yield will fluctuate depending upon market conditions, the type,
quality, and maturity of the instruments in the Fund, and its expenses.

Charges Under Variable Life Insurance and Variable Annuity Policies

     Yield and total return quotations do not reflect any charges imposed on any
Separate Account or otherwise imposed pursuant to the variable life insurance
policies and variable annuity contracts that are supported by the Funds. (Those
charges are discussed in the prospectus for such policies or contracts.)
Therefore, the yield or total return of any Fund is not comparable to that of a
publicly available fund. Nor should yield or total return quotations be
considered representative of the Fund's yield or total return in any future
period.

APPENDIX A
- ----------

                             CORPORATE BOND RATINGS

     Moody's Investors Service, Inc., describes its ratings for corporate bonds
as follows:

 .    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.

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

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

 .    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.

 .    Bonds which are rated Ba have speculative elements and their future cannot
     be considered as well assured. 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. Bonds in this class are characterized
     by uncertainty of position.

 .    Bonds which are rated B generally lack characteristics of a 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.

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

 .    Bonds which are rated Ca are speculative in a high degree. They are often
     in default or have other marked shortcomings.

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

     Standard & Poor's Corporation describes its ratings for corporate bonds as
follows:

 .    AAA - - This is the highest rating assigned by Standard & Poor's to a debt
     obligation and indicates an extremely strong capacity to pay principal and
     interest.

                                      51
<PAGE>

 .    AA -- Bonds rated AA also qualify as high-quality 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 a 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, C -- Bonds rated in these categories 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 C the highest
     degree of speculation. While this debt will likely have some quality and
     protective characteristics, these are outweighed by large uncertainties or
     major risk exposures to adverse conditions.

 .    C1 -- This rating 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.

ITEM 25. INDEMNIFICATION

Reference is made to Article VI of the Registrant's By-Laws (Exhibit 2 to
Post-Effective Amendment No. 3 to this Registration Statement filed in April,
1988), which provides that the Trust shall indemnify or advance any expenses to
the trustees, shareholders, officers, or employees of the Trust to the extent
set forth in the Declaration of Trust.

Sections 6.3 through 6.17 of the Declaration of Trust (Exhibit 1 to Post-
Effective Amendment No. 3 to this Registration Statement filed in April, 1988),
relate to the indemnification of trustees, shareholders, officers and employees
and are hereby incorporated by reference. It is provided that the Registrant
shall indemnify any Trustee made a party to any proceeding by reason of service
in that capacity if the Trustee (a) acted in good faith and (b) reasonably
believed, (1) in the case of conduct in the Trustee's official capacity with the
Trust, that the conduct was in the best interest of the Trust and (2) in all
other cases, that the conduct was at least not opposed to the best interests of
the Trust, and (c) in the case of any criminal proceeding, the Trust shall
indemnify the Trustee if the Trustee acted in good faith and had no reasonable
cause to believe that the conduct was unlawful. Indemnification may not be made
by the Trust unless authorized in each case by a determination by the Board of
Trustees or by special legal counsel or by the shareholders. Neither
indemnification nor advancement of expenses may be made if the Trustee or
officer has incurred liability by reason of willful misfeasance, bad faith,
gross negligence, or reckless disregard of duties involved in the conduct of his
office ("Disabling Conduct"). The means for determining whether indemnification
shall be made shall be (1) a final decision on the merits by a court or other
body before whom the proceeding was brought that the person to be indemnified
was not liable by reason of Disabling Conduct or (2) in the absence of such a
decision, a reasonable determination, based upon a review of the facts, that
such person was not liable by reason of Disabling Conduct. Such latter
determination may be made either (a) by the vote of a majority of a quorum of
Trustees who are neither "interested persons" of the Trust (as defined in the
1940 Act, as amended) nor parties to the proceeding or (b) by an independent
legal counsel in a written opinion. The advancement of legal expenses may not
occur unless the Trustee or officer agrees to repay the advance (unless it is
ultimately determined that he is entitled to indemnification) and at least one
of three conditions is satisfied: (1) he provides security for his agreement to
repay, (2) the Registrant is insured against loss by reason of lawful advances,
or (3) a majority of a quorum the Trustees who are not interested persons and
are not parties to the proceedings, or independent counsel in a written opinion,
determine that there is reason to believe that the Trustee or officer will be
found entitled to indemnification.

Agency Agreement by and between John Hancock Variable Series Fund I, Inc., and
John Hancock Mutual Life Insurance Company (Exhibit 9 to Pre-Effective Amendment
No. 1 to this Registration Statement filed March 13, 1986), and Section 6 of the
Underwriting and Indemnity Agreement By and Among John Hancock Series Trust,
John Hancock Distributors, Inc., and John Hancock Mutual Life Insurance Company
(Exhibit 6.b to Post-Effective Amendment No. 14 to this Registration Statement
filed February 28, 1997).

Insofar as indemnification for liabilities arising under the Securities Act of
1933 may be permitted to trustees, officers, and controlling persons of the
Registrant pursuant to the Registrant's By-Laws or otherwise, the Registrant has
been advised that, in the opinion of the Securities and Exchange Commission (the
"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, or
proceeding) is asserted by such trustee, officer, or controlling person in
connection with the securities being registered, then the Registrant will,
unless in the opinion of its counsel the matter has been settled by a
controlling precedent, submit to a court of appropriate jurisdiction the
question of whether indemnification by it is against public policy as expressed
in the Act and will be governed by the final adjudication of such issue.

                       AMENDMENT TO CUSTODIAN AGREEMENT

     This Amendment to the Custodian Agreement is made as of December 18, 1998
by and between the John Hancock Variable Series Trust I (the "Fund") and State
Street Bank and Trust Company (the "Custodian"). Capitalized terms used in this
Amendment without definition shall have the respective meanings given to such
terms in the Custodian Agreement referred to below.

     WHEREAS, the Fund and the Custodian entered into an Amended and Restated
Custodian Agreement dated as of January 30, 1995 (as amended and in effect from
time to time, "Contract"); and

     WHEREAS, the Fund is authorized to issue shares in separate series, with
each such series representing interests in a separate portfolio of securities
and other assets, and the Fund has made twenty-three (23) series subject to the
Contract (each such series, together with all other series subsequently
established by the Fund and made subject to the Contract in accordance with the
terms thereof, shall be referred to as a "Portfolio", and, collectively, the
"Portfolios"); and

     WHEREAS, the Fund and the Custodian desire to amend certain provisions of
the Contract to reflect revisions to Rule 17f-5 ("Rule 17f-5") promulgated under
the Investment Company Act of 1940, as amended (the "1940 Act"); and

     WHEREAS, the Fund and the Custodian desire to amend and restate certain
other provisions of the Contract relating to the custody of assets of each of
the Portfolios held outside of the United States.

    NOW THEREFORE, in consideration of the foregoing and the mutual covenants
and agreements hereinafter contained, the parties hereby agree to amend the
Contract, pursuant to the terms thereof, as follows:

I.    Articles 4 through 15 of the Contract are hereby renumbered, as of the
      effective date of this Amendment, as Articles 6 through 17, respectively,
      and all cross-references therein are hereby renumbered accordingly.

II.   New Articles 4 and 5 of the Contract are hereby added, as of the effective
      date of this Amendment, as set forth below. Said new Articles 4 and 5
      shall govern matters relating to (a) the responsibilities of the Custodian
      as "Foreign Custody Manager" (as hereinafter defined) for each Portfolio
      of the Fund that is subject to the Contract, and (b) the responsibilities
      of the Custodian with respect to property of any such Portfolio that is
      held outside the United States. In the event of any conflict between the
      provisions of new Articles 4 and 5, on the one hand, and any


<PAGE>

      other provision of the Contract, on the other hand, the provisions of new
      Articles 4 and 5 shall prevail.

III.  Except as specifically superseded or modified herein, the terms and
      provisions of the Contract shall continue to apply with full force and
      effect. If the Custodian is delegated the responsibilities of Foreign
      Custody Manager pursuant to the terms of Article 4 hereof, in the event of
      any conflict between the provisions of Articles 4 and 5 hereof, the
      provisions of Article 4 shall prevail.

the Custodian as Foreign Custody Manager for that country shall be deemed to

responsibilities delegated pursuant to this Contract to the Custodian as the

5.5.  Registration of Foreign Securities.
      ----------------------------------

The foreign securities maintained in the custody of a Foreign Sub-Custodian
(other than bearer securities) shall be registered in the name of the applicable
Portfolio or in the name of the Custodian or in the name of any Foreign
Sub-Custodian or in the name of any nominee of the foregoing, and the Fund on
behalf of such Portfolio agrees to hold any such nominee harmless from any
liability as a holder of record of such foreign securities. The Custodian or a
Foreign Sub-Custodian shall not be obligated to accept securities on behalf of a
Portfolio under the terms of this Contract unless the form of such securities
and the manner in which they are delivered are in accordance with reasonable
market practice.

5.6.  Bank Accounts.
      -------------

The Custodian shall identify on its books as belonging to the Fund cash
(including cash denominated in foreign currencies) deposited with the Custodian.
Where the Custodian is unable to maintain, or market practice does not
facilitate the maintenance of, cash on the books of the Custodian, a bank
account or bank accounts opened and maintained outside the United States on
behalf of a Portfolio with a Foreign Sub-Custodian shall be subject only to
draft or order by the Custodian or such Foreign Sub-Custodian, acting pursuant
to the terms of this Contract to hold cash received by or from or for the
account of the Portfolio.

5.7.  Collection of Income.
      --------------------

The Custodian shall use reasonable commercial efforts to collect all income and
other payments with respect to the Foreign Assets held hereunder to which the
Portfolios shall be entitled and shall credit such income, as collected, to the
applicable Portfolio. In the event that extraordinary measures are required to
collect such income, the Fund and the Custodian shall consult as to such
measures and as to the compensation and expenses of the Custodian relating to
such measures.

5.8.  Shareholder Rights.
      ------------------

With respect to the foreign securities held pursuant to this Article 5, the
Custodian will use reasonable commercial efforts to facilitate the exercise of
voting and other shareholder rights, subject always to the laws, regulations and
practical constraints that may exist in the country where such securities are
issued. The Fund acknowledges that local conditions, including lack of
regulation, onerous procedural obligations, lack of notice and other factors may
have the effect of severely limiting the ability of the Fund to exercise
shareholder rights.

<PAGE>

5.9.  Communications Relating to Foreign Securities.
      ---------------------------------------------

The Custodian shall transmit promptly to the Fund written information
(including, without limitation, pendency of calls and maturities of foreign
securities and expirations of rights in connection therewith) received by the
Custodian via the Foreign Sub-Custodians from issuers of the foreign securities
being held for the account of the portfolios. With respect to tender or exchange
offers, the Custodian shall transmit promptly to the Fund written information so
received by the Custodian from issuers of the foreign securities whose tender or
exchange is sought or from the party (or its agents) making the tender or
exchange offer. The Custodian shall not be liable for any untimely exercise of
any tender, exchange or other right or power in connection with foreign
securities or other property of the Portfolios at any time held by it unless (i)
the Custodian or the respective Foreign Sub-Custodian is in actual possession of
such foreign securities or property and (ii) the Custodian receives Proper
Instructions with regard to the exercise of any such right or power, and both
(i) and (ii) occur at least three business days prior to the date on which the
Custodian is to take action to exercise such right or power.

5.10. Liability of Foreign Sub-Custodians and Foreign Securities Systems.
      ------------------------------------------------------------------

Each agreement pursuant to which the Custodian employs a Foreign Sub-Custodian
shall to the extent possible, require the Foreign Sub-Custodian to exercise
reasonable care in the performance of its duties and, to the extent possible to
indemnify, and hold harmless, the Custodian from and against any loss, damage,
cost, expense, liability or claim arising out of or in connection with the
Foreign Sub-Custodian's performance of such obligations. At the Fund's
election, the Portfolios shall be entitled to be subrogated to the rights of
the Custodian with respect to any claims against a Foreign Sub-Custodian as a
consequence of any loss, damage, cost, expense, liability or claim if and to the
extent that the Portfolios have not been made whole for any such loss, damage,
cost, expense, liability or claim. At the Fund's request, the Custodian shall
use reasonable efforts to process and advance any such claim on behalf of the
Fund against any Foreign Sub-Custodian or Foreign Securities System.

5.11. Tax Law.
      -------

The Custodian shall have no responsibility or liability for any obligations now
or hereafter imposed on the Fund, the Portfolios or the Custodian as custodian
of the Portfolios by the tax law of the United States or of any6 state or
political subdivision thereof. It shall be the responsibility of the Fund to
notify the Custodian of the obligations imposed on the Fund with respect to the
Portfolios or the Custodian as custodian of the Portfolios by the tax law of
countries other than those mentioned in the above sentence, including
responsibility for withholding and other taxes, assessments or other
governmental charges, certifications and governmental reporting. The sole
responsibility of the Custodian with regard to such tax law shall be to promptly
notify the Fund of any claim or other notice received by the Custodian relating
to taxes owed by the

                                      11
<PAGE>

Fund (or any report relating thereto), and to use reasonable efforts to assist
the Fund with respect to any claim for exemption or refund under the tax law of
countries for which the Fund has provided such information. Subject to the
foregoing, it shall be the responsibility of the Custodian to use reasonable
efforts to perform such ministerial steps as are required to collect any tax
refund, to ascertain the appropriate rate of tax withholding and to provide such
documents as may be required to enable the Company to receive appropriate tax
treatment under applicable tax laws and treaty provisions, if any.

5.12. Liability of Custodian.
      ----------------------

Except as may arise from the Custodian's own negligence or willful misconduct or
the negligence or willful misconduct of a Foreign Sub-Custodian, the Custodian
shall be without liability to the Fund for any loss, liability, claim or expense
resulting from or caused by anything which is (A) part of Country Risk or (B)
part of the "prevailing country risk" of the Fund and the Portfolios, as such
term is used in SEC Release Nos. IC-22658; IS-1080 (May 12, 1997) or as such
term or other similar terms are now or in the future interpreted by the SEC or
by the staff of the Division of Investment Management of the SEC.

The Custodian shall be liable for the acts or omissions of a Foreign
Sub-Custodian or a Foreign Securities System to the same extent as set forth
with respect to sub-custodians and Securities Systems generally in the Contract
provided however that regardless of whether Foreign Assets are maintained in the
custody of a Foreign Sub-Custodian or a Foreign Securities System, the Custodian
shall not be liable for any loss, damage, cost, expense, liability or claim
resulting from nationalization, expropriation, currency restrictions, or acts of
war or terrorism, or any other loss where the Foreign Sub-Custodian has
otherwise acted with reasonable care. Nothing herein shall be deemed to relieve
the Custodian from liability for its own negligent or willful acts and
omissions, or other breach of this Contract.

                                  April 5, 2000

John Hancock Variable Series Trust I
John Hancock Place
P.O. Box 111
Boston, MA 02117

Trustees:

     This opinion is given in connection with the filing by John Hancock
Variable Series Trust I, a Massachusetts business trust (the "Trust") of its
Post-Effective Amendment No. 24 to its Registration Statement on Form N-1A (File
No. 33-2081; the "Registration Statement") under the Securities Act of 1933 and
the Investment Company Act of 1940, relating to an indefinite amount of its
shares of beneficial interest, which includes thirty-one separate series (i.e.,
the Managed, Growth & Income, Equity Index, Large Cap Value, Large Cap Growth,
Mid Cap Value, Mid Cap Growth, Small/Mid Cap Growth, Real Estate Equity,
Small/Mid Cap CORE Equity, Small Cap Value, Small Cap Growth, Global Equity,
International Balanced, International Equity Index, International Opportunities,
Emerging Markets Equity, Short-Term Bond, Bond Index, Sovereign Bond, Global
Bond, High Yield Bond, Large Cap Aggressive Growth, Fundamental Mid Cap Growth,
International Equity, Aggressive Balanced, Large Cap Value CORE, Large/Mid Cap
Value, Mid Cap Blend, Small/Mid Cap Value, and Money Market Funds). The Trust's
shares of beneficial interest, including the thirty-one series of shares, are
hereinafter referred to as the "shares".

     I have examined the Trust's Declaration of Trust, its By-Laws, the
Registration Statement of its predecessor as originally filed on December
11, 1985, subsequent post-effective amendments and this Post-Effective Amendment
No. 24, and such other records, certificates, documents and statutes that I have
deemed relevant in order to render the opinion expressed herein.

     Based on such examination, I am of the opinion that:

     1.   The Trust is a business trust duly organized, validly existing and in
          good standing under the laws of the Commonwealth of Massachusetts.

     2.   The shares offered for sale by the Trust, when issued in the manner
          contemplated by this Post-Effective Amendment to its Registration
          Statement, will be legally issued, fully-paid and non-assessable.

Amendment to the Registration Statement and to the use of my name in the

                                 CODE OF ETHICS

                      JOHN HANCOCK VARIABLE SERIES TRUST I

                             Revised February, 2000

                                 CODE OF ETHICS
                           (Revised February16, 2000)

                      JOHN HANCOCK VARIABLE SERIES TRUST I

           The conduct of each "Access Person" to the John Hancock Variable
Series Trust I (the "Trust"), a registered investment company, is governed by
one basic principle: the interests of investors in the Trust are paramount. In
recognition of the applicable fiduciary principles, the personal interests of
each "Access Person" must be subordinated to those of the investors. Thus, no
Access Person may make personal use of information available by reason of his or
her position with the Trust until after investment transactions of the Funds
within the Trust' have been completed.

           Each investment opportunity which comes to the attention of any
Access Person which is appropriate for consideration by the Trust must first be
made available to the Trust before he or she can take any personal advantage of
the opportunity. A conflict between the interest of an individual and that of
the Trust can arise when the individual by reason of his or her position
anticipates a portfolio transaction by the investing entity and places himself
or herself in a position to profit by the Trust's action. A conflict can also
arise when an individual who has an existing securities position in his or her
personal account can benefit from the purchase, sale or retention of the same
security by the Trust.

           The following requirements set forth below are designed to assist
those individuals subject to this Code in their personal securities transactions
by clearly specifying some, but not all, of the areas where personal
transactions might raise questions of conflict with the best interests of
investors in the Trust.

1.   DEFINITIONS

17.  INTERPRETATION AND ENFORCEMENT
     ------------------------------

This Code of Ethics cannot anticipate every situation in which personal
interests may be in conflict with the interests of the investors in the Trust.
Attention should be given to the spirit and intent of the Code as well as its
specific provisions.

When any doubt exists regarding any provision of the Code or whether a conflict
of interest might exist, the transaction should be discussed beforehand with the
Trust's Compliance Officer.

The Code of Ethics is designed to detect and prevent fraud against investors,
and to avoid the appearance of impropriety. To provide assurance that policies
are effective, personal securities transaction reports will be monitored and
checked against the Fund's and Accounts' portfolio transactions. Any deviations
from the policies will be reported to the Compliance Officer. In addition, other
internal auditing procedures may be adopted from time to time.

Violations of the Code will be referred by the Trust's Compliance Officer to
JHLICO's General Counsel for review and appropriate action. Sanctions for
violations could include fines, suspension, letter of reprimand or termination
of the violator's position and/or a report to the appropriate regulatory
authority.
