Your Investment Choices
- --------------------------------------------------------------------------------

The Declaration funds offer you 6 investment choices to suit a variety of
objectives. Each fund has its own strategy and its own risk/reward profile.

[Clip Art] Growth Funds

o  V.A. Financial Industries Fund

This fund seeks long-term growth by investing primarily in common stocks. It may
be appropriate if you are investing for long-term goals such as retirement and
are willing to accept higher short-term risk along with higher potential
long-term returns. Because growth funds will go up and down in value, they may
not be appropriate if you are uncomfortable with stock market risk or have a
shorter investment time horizon.

[Clip Art]  Growth & Income Funds

o  V.A. Core Equity Fund

o  V.A. Sovereign Investors Fund

These funds invest for varying combinations of income and capital appreciation.
Because of their income potential, they may be appropriate if you are looking
for a more conservative alternative to exclusively growth-oriented funds.
However, they may not be appropriate if you are investing for maximum return
over a long time horizon or need stability of principal.

[Clip Art] Income Funds

o  V.A. Bond Fund

o  V.A. Money Market Fund

o  V.A. Strategic Income Fund

These funds seek to provide current income without sacrificing total return, and
some also invest for stability of principal. They may be appropriate if you are
seeking a regular stream of income. They may not be appropriate if you are
investing for maximum return or need absolute stability of your principal.


                                                                               5
<PAGE>

V.A. Financial Industries Fund

GOAL AND STRATEGY

[Clip Art] The fund seeks capital appreciation. To pursue this goal, the fund
normally invests at least 65% of assets in U.S. and foreign financial services
companies, including banks, thrifts, finance companies, brokerage and advisory
firms, real estate-related firms and insurance companies.

In managing the portfolio, the managers concentrate primarily on stock selection
rather than industry allocation. The portfolio may include financial services
companies of all sizes and types.

In choosing individual stocks, the managers use fundamental financial analysis
to identify securities that appear comparatively undervalued. Given the
industrywide trend toward consolidation, the managers also seek out companies
that appear to be positioned for a merger. The managers generally gather
firsthand information about companies from interviews and company visits.

The fund may invest in U.S. and foreign bonds, including up to 5% of net assets
in junk bonds (those rated below BBB/Baa and their unrated equivalents). It may
also invest up to 15% of assets in investment-grade short-term securities.

The fund may make limited use of certain derivatives (investments whose value is
based on indices, securities or currencies).

In abnormal market conditions, the fund may temporarily invest up to 80% of
assets in investment-grade short-term securities. In these and other cases, the
fund might not achieve its goal.

The fund may trade securities actively, which could increase its transaction
costs, thus lowering performance.

MAIN RISKS

[Clip Art] As with most growth funds, the value of your investment will go up
and down in response to stock market movements. Another major factor in this
fund's performance is the economic condition of the financial services sector.
The value of your investment may fluctuate more widely than it would in a fund
that is diversified across sectors.

When interest rates fall or economic conditions deteriorate, the stocks of
financial services companies often suffer greater losses than other stocks.
Rising interest rates can cut into profits by reducing the difference between
these companies' borrowing and lending rates.

The fund's management strategy will influence performance significantly. Stocks
of financial services companies as a group could fall out of favor with the
market, causing the fund to underperform funds that focus on other types of
stocks. Similarly, if the managers' stock selection strategy doesn't perform as
expected, the fund could underperform its peers or lose money.

To the extent that the fund makes investments with additional risks, those risks
could increase volatility or reduce performance:

o  Foreign investments carry additional risks, including potentially unfavorable
   currency exchange rates, inadequate or inaccurate financial information and
   social or political upheavals.

o  In a down market, higher-risk securities and derivatives could become harder
   to value or to sell at a fair price.

o  Any bonds held by the fund could be downgraded in credit rating or go into
   default. Bond prices generally fall when interest rates rise. Junk bond
   prices can fall on bad news about the economy, an industry or a company.

o  Certain derivatives could produce disproportionate gains or losses.

V.A. Core Equity Fund

GOAL AND STRATEGY

[Clip Art] The fund seeks above-average total return (capital appreciation plus
income). To pursue this goal, the fund invests in a diversified portfolio of
primarily large-capitalization stocks. The portfolio's risk profile is similar
to that of the S&P 500 Index.

The managers select from a menu of stocks of approximately 550 companies that
evolves over time. Approximately 70% to 80% of these companies also are included
in the S&P 500 Index. The subadviser's investment research team is organized by
industry and tracks these companies to develop earnings estimates and five-year
projections for growth. A series of proprietary computer models uses this
in-house research to rank the stocks according to their combination of:

o  value, meaning they appear to be underpriced

o  momentum, meaning they show potential for strong growth

This process, together with a risk/return analysis against the S&P 500 Index,
results in a portfolio of approximately 100 to 130 of the stocks from the top
60% of the menu. The fund must sell any stocks that fall into the bottom 20% of
the menu.

In normal market conditions, the fund is almost entirely invested in stocks. The
fund may, however, invest in certain other types of equity and debt securities,
including dollar-denominated foreign securities. It may also make limited use of
certain derivatives (investments whose value is based on indices or securities).

In abnormal market conditions, the fund may temporarily invest more than 35% of
assets in investment-grade short-term securities. In these and other cases, the
fund might not achieve its goal.

The fund may trade securities actively, which could increase its transaction
costs, thus lowering performance.

MAIN RISKS

[Clip Art] The value of your investment will go up and down in response to stock
market movements. Large-capitalization stocks as a group could fall out of favor
with the market, causing the fund to underperform funds that focus on small- or
medium-capitalization stocks.

The fund's management strategy will influence performance significantly. If the
investment research team's earnings estimates or projections turn out to be
inaccurate, or if the proprietary computer models don't perform as expected, the
fund could underperform its peers or lose money.

To the extent that the fund makes investments with additional risks, those risks
could increase volatility or reduce performance:

o  Foreign investments carry additional risks, including potentially inadequate
   or inaccurate financial information and social or political upheavals.

o  Certain derivatives could produce disproportionate gains or losses.

o  In a down market, higher-risk securities and derivatives could become harder
   to value or to sell at a fair price.

V.A. Sovereign Investors Fund

GOAL AND STRATEGY

[Clip Art] The fund seeks long-term growth of capital and income without
assuming undue market risks. To pursue these goals, the fund normally invests
most of its assets in a diversified portfolio of stocks, although it may respond
to market conditions by investing in other types of securities, such as bonds or
short-term securities.

All of the fund's stock investments are "dividend performers" -- companies whose
dividend payments have increased steadily for ten years. The managers use
fundamental financial analysis to identify individual companies with
high-quality income statements, substantial cash reserves and identifiable
catalysts for growth, which may be new products or benefits from industrywide
growth. The managers generally visit companies to evaluate the strength and
consistency of their management strategy. Finally, the managers look for stocks
that are reasonably priced relative to their earnings and industry.
Historically, companies that meet these criteria have tended to have large or
medium capitalizations.

The fund may invest in bonds of any maturity, with up to 5% of assets in junk
bonds rated as low as C and their unrated equivalents.

The fund typically invests in U.S. companies but may invest in
dollar-denominated foreign securities. It may also make limited use of certain
derivatives (investments whose value is based on indices or securities).

In abnormal market conditions, the fund may temporarily invest extensively in
investment-grade short-term securities. In these and other cases, the fund might
not achieve its goal.

The fund may trade securities actively, which could increase its transaction
costs, thus lowering performance.

MAIN RISKS

[Clip Art] The value of your investment will go up and down in response to stock
and bond market movements.

The fund's management strategy will influence performance significantly. Large-
or medium-capitalization stocks as a group could fall out of favor with the
market, causing the fund to underperform funds that focus on small-
capitalization stocks. Similarly, if the managers' securities selection
strategies don't perform as expected, the fund could underperform its peers or
lose money.

To the extent that the fund makes investments with additional risks, those risks
could increase volatility or reduce performance:

o  Any bonds held by the fund could be downgraded in credit rating or go into
   default. Bond prices generally fall when interest rates rise and longer
   maturity will increase volatility. Junk bond prices can fall on bad news
   about the economy, an industry or a company.

o  Certain derivatives could produce disproportionate gains or losses.

o  In a down market, higher-risk securities and derivatives could become harder
   to value or to sell at a fair price.

o  Foreign investments carry additional risks, including inadequate or
   inaccurate financial information and social or political upheavals.

V.A. Bond Fund

GOAL AND STRATEGY

[Clip Art] The fund seeks to generate a high level of current income consistent
with prudent investment risk. In pursuing this goal, the fund normally invests
in a diversified portfolio of debt securities. These include corporate bonds and
debentures, as well as U.S. government and agency securities. Most of these
securities are investment-grade, although the fund may invest up to 25% of
assets in junk bonds rated as low as CC/Ca and their unrated equivalents. There
is no limit on the fund's average maturity.

In managing the fund's portfolio, the managers concentrate on sector allocation,
industry allocation and securities selection: deciding which types of bonds and
industries to emphasize at a given time, and then which individual bonds to buy.
When making sector and industry allocations, the managers try to anticipate
shifts in the business cycle, using top-down analysis to determine which sectors
and industries may benefit over the next 12 months.

In choosing individual securities, the managers use bottom-up research to find
securities that appear comparatively undervalued. The managers look at bonds of
all different quality levels and maturities from many different issuers,
potentially including foreign governments and corporations.

The fund intends to keep its exposure to interest rate movements generally in
line with those of its peers. The fund may use certain derivatives (investments
whose value is based on indices, securities or currencies), especially in
managing its exposure to interest rate risk, although it does not intend to use
them extensively.

In abnormal market conditions, the fund may temporarily invest more than 35% of
assets in investment-grade short-term securities. In these and other cases, the
fund might not achieve its goal.

The fund may trade securities actively, which could increase its transaction
costs, thus lowering performance.

MAIN RISKS

[Clip Art] The major factors in this fund's performance are interest rates and
credit risk. When interest rates rise, bond prices generally fall. Generally, an
increase in the fund's average maturity will make it more sensitive to interest
rate risk.

The fund could lose money if any bonds it owns are downgraded in credit rating
or go into default. In general, lower-rated bonds have higher credit risks. If
certain sectors or investments don't perform as the fund expects, it could
underperform its peers or lose money.

To the extent that the fund makes investments with additional risks, those risks
could increase volatility or reduce performance:

o  Junk bonds and foreign securities may make the fund more sensitive to market
   or economic shifts in the U.S. and abroad.

o  If interest rate movements cause the fund's mortgage-related and callable
   securities to be paid off substantially earlier or later than expected, the
   fund's share price or yield could be hurt.

o  In a down market, higher-risk securities and derivatives could become harder
   to value or to sell at a fair price.

o  Certain derivatives could produce disproportionate gains or losses.

Any U.S. government guarantees on portfolio securities do not apply to these
securities' market value or current yield, or to fund shares.

V.A. Money Market Fund

GOAL AND STRATEGY

[Clip Art] The fund seeks maximum current income consistent with capital
preservation and liquidity. It invests only in high-quality money market
instruments and seeks to maintain a stable share price of $1.

The fund invests only in dollar-denominated securities rated within the two

Main Risks

[Clip Art] The value of your investment will be most affected by short-term
interest rates. If interest rates rise sharply, the fund could underperform its
peers or lose money.

An issuer of securities held by the fund could default or have its credit rating
downgraded.

Foreign investments carry additional risks, including inadequate or inaccurate
financial information and social or political upheavals.

An investment in the fund is not insured or guaranteed by the Federal Deposit
Insurance Corporation or any other government agency. Although the fund seeks to
preserve the value of your investment at $1 per share, it is possible to lose
money by investing in the fund.

V.A. Strategic Income Fund

GOAL AND STRATEGY

[Clip Art] The fund seeks a high level of current income. In pursuing this goal,
the fund invests primarily in the following types of securities:

o  foreign government and corporate debt securities from developed and emerging
   markets

o  U.S. government and agency securities

o  U.S. junk bonds

Although the fund invests in securities rated as low as CC/Ca and their unrated
equivalents, it generally intends to keep its average credit quality in the
investment-grade range. There is no limit on the fund's average maturity.

In managing the portfolio, the managers allocate assets among the three major
sectors based on analysis of economic factors such as projected international
interest rate movements, industry cycles and political trends.

Within each sector, the managers look for securities that are appropriate for
the overall portfolio in terms of yield, credit quality, structure and industry
distribution. In selecting securities, relative yields and risk/reward ratios
are the primary considerations.

The fund may use certain higher-risk investments, including derivatives
(investments whose value is based on indices, securities or currencies) and
restricted or illiquid securities. In addition, the fund may invest up to 10% of
net assets in U.S. or foreign stocks.

In abnormal market conditions, the fund may temporarily invest extensively in
investment-grade short- term securities. In these and other cases, the fund
might not achieve its goal.

The fund may trade securities actively, which could increase its transaction
costs, thus lowering performance.

MAIN RISKS

[Clip Art] The fund's risk profile depends on its sector allocation. In general,
investors should expect fluctuations in share price, yield and total return that
are above average for bond funds.

When interest rates rise, bond prices generally fall. Generally, an increase in
the fund's average maturity will make it more sensitive to interest rate risk.

A fall in worldwide demand for U.S. government securities could also lower the
prices of these securities.

The fund could lose money if any bonds it owns are downgraded in credit rating
or go into default. In general, lower-rated bonds have higher credit risks, and
their prices can fall on bad news about the economy, an industry or a company.
If certain allocation strategies or certain industries or investments don't
perform as the fund expects, it could underperform its peers or lose money.

To the extent that the fund makes investments with additional risks, those risks
could increase volatility or reduce performance:

o  Foreign investments carry additional risks, including potentially unfavorable
   currency exchange rates, inadequate or inaccurate financial information and
   social or political upheavals. These risks are greater in emerging markets.

o  If interest rate movements cause the fund's callable securities to be paid
   off substantially earlier or later than expected, the fund's share price or
   yield could be hurt.

o  Stock investments may go down in value due to stock market movements or
   negative company or industry events.

o  In a down market, higher-risk securities and derivatives could become harder
   to value or to sell at a fair price.

o  Certain derivatives could produce disproportionate gains or losses.

Account information

- --------------------------------------------------------------------------------
BUYING AND SELLING FUND SHARES

When you invest in a Declaration fund through a variable contract, your premium
payments are used to buy units of an insurance company separate account that
then buys shares of the fund. The shares are purchased at net asset value (NAV)
and are generally credited to the separate account immediately after the fund
accepts payment from the insurance company. In unusual circumstances or to
protect shareholders, a fund may refuse a purchase order, especially when the
adviser believes the order might be large enough to disrupt the fund's
management. A fund may also temporarily suspend the offering of its shares.

Shares are sold at the next NAV to be determined after the fund accepts the sell
request. The sales proceeds are normally forwarded by bank wire to the insurance
company on the next business day. In unusual circumstances, the fund may
temporarily suspend the processing of sell requests. It may also postpone the
payment of sales proceeds for up to seven days or longer, as allowed by federal
securities laws.

- --------------------------------------------------------------------------------
VALUING FUND SHARES

The NAV for each fund is determined each business day at the close of business
on the New York Stock Exchange (typically 4:00 P.M. Eastern Time). The Exchange
is typically open Monday through Friday.

Except for V.A. Money Market Fund, which values its securities at amortized
cost, securities in a fund's portfolio are generally valued on the basis of
market quotations and valuations provided by independent pricing services. The
fund may also value securities at fair value, especially if market quotations
are not readily available or if the securities' value has been materially
affected by events following the close of a foreign market. Fair value is
determined according to procedures approved by the fund's board of trustees. If
the fund uses this method, the securities' prices may be higher or lower than
the same securities held by another fund using market quotations.

- --------------------------------------------------------------------------------
FUND EXPENSES


Management fees The management fees paid to the investment adviser by the John
Hancock Declaration funds last year are as follows:

- --------------------------------------------------------------------------------
 Growth Funds                            % of net assets
- --------------------------------------------------------------------------------
 V.A. Financial Industries Fund          0.80%

- --------------------------------------------------------------------------------
 Growth & Income Funds
- --------------------------------------------------------------------------------
 V.A. Core Equity Fund                   0.70%
 V.A. Sovereign Investors Fund           0.60%

- --------------------------------------------------------------------------------
 Income Funds
- --------------------------------------------------------------------------------
 V.A. Bond Fund                          0.50%
 V.A. Money Market Fund                  0.50%
 V.A. Strategic Income Fund              0.60%


The adviser pays subadvisory fees out of its own assets and no fund is
responsible for paying a fee to its sub-adviser.

Expense limitation The adviser may reduce its fee or make other arrangements to
limit each fund's expenses to a specified percentage of average daily net
assets. The adviser has agreed to limit temporarily each fund's expenses to
0.25% of average net assets, excluding advisory fees, at least until May 1,
2000. If annual expenses fall below this limitation at the end of any fund's
fiscal year, the adviser can impose the full fee and recover any other payments
up to the amount of the limitation.

- --------------------------------------------------------------------------------
DIVIDENDS AND TAXES

All income and capital gain distributions are automatically reinvested in
additional shares of the fund at net asset value and are includable in the
separate accounts holding these shares. For a discussion of the tax status of
your variable contract, including the tax consequences of withdrawals or other
payments, refer to the prospectus of your insurance company's separate account.

BUSINESS STRUCTURE

When you invest in a Declaration fund through a variable contract, your premium
payments are used to buy units of an insurance company separate account that
then buys shares of the fund. The diagram below shows the basic business
structure used by the Declaration funds. The funds' board of trustees oversees
the funds' business activities and retains the services of the various firms
that carry out the funds' operations.

The trustees of the Declaration funds have the power to change the funds'
investment goals without shareholder or contract holder approval.

Year 2000 compliance The adviser and the funds' service providers are taking
steps to address any year 2000-related computer problems. However, there is some
risk that these problems could disrupt the issuers in which the funds invest,
the funds' operations or financial markets generally.
