                                  Managed Fund


PROPOSALS 1A - 1C:  New Investment Management Agreements
--------------------------------------------------------------------------------

Q.   What changes to the investment management agreements are being proposed for
the Managed Fund?

A.   The Board unanimously approved, and is recommending that shareholders
approve, the following:

     (1)  two new Sub-Investment Management Agreements that reflect a
          "multi-manager" investment approach and provide for the addition of a
          second sub-advisor for the Fund; and

     (2)  a related amendment to the Investment Management Agreement that would
          increase fees the Fund pays to John Hancock for management of the
          Fund.

Q.   What is a multi-manager approach?  Why is it recommended for the Managed
Fund?

A.   The multi-manager approach combines different investment managers and
strategies with the goal of producing more consistent investment performance
over market cycles. Performance consistency is considered a primary goal of the
Managed Fund since its balanced strategy makes it a core investment option for
investors. The Board is recommending the combination of two sub-advisors --
Independence Investment Associates (IIA), the current sub-advisor, with Capital
Guardian, a new sub-advisor -- to reduce the Fund's exposure to the risk of any
one manager or strategy being out of favor in certain market environments.

Q.   Why Capital Guardian?

A.   Capital Guardian provides:

     .    a strong organization with the experience, significant resources and a
          well-defined investment process for the management of domestic
          balanced portfolios;

     .    an excellent long-term performance record and competitive
          sub-investment advisory fees in managing domestic balanced portfolios;
          and,

     .    a premier reputation in the variable products marketplace and the
          potential for increased growth in Fund assets with it as the new
          sub-advisor.

Q.   Why the combination of IIA and Capital Guardian?

A.   IIA and Capital Guardian have distinct and complementary approaches in
managing domestic balanced portfolios. The goal in combining the two approaches
is to produce more consistent investment returns over market cycles.
<PAGE>

Q.  Why is a change in the investment management fee recommended?

A.  The proposed fee increase reflects the difference between Capital Guardian's
fee schedule and that of the current sub-advisor; the additional resources for
fund administration, investment oversight and technology that the multi-manager
approach requires; and an adjustment to the investment management fee paid to
John Hancock -- which has remained the same since the mid 1980s -- to compensate
for the significant increase since then in the complexity and cost of managing
and servicing the Fund.

Q.  How will the investment management fee be modified?

A.  The Board is recommending an increase in the annual percentage rates that
are applied to different levels of Fund assets to determine the amount the Fund
pays to John Hancock for investment management. Total fund expenses include
these investment management fees plus other non-advisory expenses (0.03% of
assets in 1999).

This means that if a shareholder had on average $10,000 in the Managed Fund
during 1999 and the proposed fee structure had been in place for all of 1999,
then the shareholder would have incurred about $35 in additional fund
expenses.

Q.  How will the Fund compare with similar funds in terms of total fund
expenses?

A.  The current expense ratio (total fund expenses divided by fund assets) for
the Fund is far below the average expense ratio for comparable funds within the
variable insurance products marketplace having a similar investment focus. Even
after the proposed change, the Fund's expense ratio will still be below the
average expense ratio for comparable funds.

Q.  How did the Board reach its conclusion to recommend this proposal?

A.  The Board, including the Independent Trustees in consultation with
independent counsel to the Trust, requested and evaluated a variety of
information provided by John Hancock. The Board carefully considered a number of
factors that are highlighted in this Q & A and detailed in the proxy statement.
These factors include the Fund's competitive performance and the increased
complexity and commitment of resources required by John Hancock in managing and
servicing the fund. After thorough study, the Board concluded that the new
management fee arrangements were fair and reasonable and would provide John
Hancock with the necessary financial incentives to promote the Fund within its
variable insurance products.

Q.  How will you benefit from all of this?

A.  As a shareholder, you will benefit from the multi-manager approach and gain
access to the investment talent and expertise of Capital Guardian, an investment
manager with significant investment resources and a strong performance record.
In addition, the increased fees will enable John Hancock to continue to dedicate
additional personnel and
<PAGE>

resources to the Fund, oversee the more complex multi-manager investment
approach and promote the Fund within its variable insurance products.

Q.  What is the Board's recommendation regarding the modifications in Proposals
1A-1C?

A.  The Board unanimously recommends that you vote "FOR" Proposals 1A-1C.
<PAGE>

                                  Managed Fund


Proposal 1D: Non-diversified Status
--------------------------------------------------------------------------------

Q.  Why is "non-diversified" status being recommended for the Managed Fund?

A.  As a diversified fund, the Managed Fund is restricted to investing a maximum
of 5% in a single issuer with respect to 75% of the Fund's total assets. In a
multi-manager structure, using two separate and distinct investment strategies
could potentially cause the overall Fund to exceed those limits. In addition,
the markets have evolved such that many individual issuers represent close to or
more than 5% of the overall market or appropriate market benchmark. Therefore,
"non-diversified" status will provide the necessary flexibility for each
sub-advisor to implement its investment strategy within a multi-manager
framework.

Q.  Will this increase the risk of investing in this Fund?

A.  When it is exercised, non-diversified status presents the risk of higher
issuer concentration. However, the Fund will maintain overall risk control and
diversification through, among other things, diversity of managers, number of
securities, sector exposures and exposure to top 10 holdings.

Q.  What is the Board's recommendation regarding the modifications in
Proposal 1D?

A.  The Board unanimously recommends that you vote "FOR" Proposal 1D.

                              Growth & Income Fund


ProposalS 2a-2C:  New Investment Management Agreements
--------------------------------------------------------------------------------

Q.   What modifications to the investment management agreements are being
proposed for the Growth & Income Fund?

A.   The Board unanimously approved, and is recommending that shareholders
approve, the following:

     (1)  two new Sub-Investment Management Agreements that reflect a
          "multi-style and multi-manager" investment approach and provide for
          the addition of a second sub-advisor for the Fund; and

     (2)  a related amendment to the Investment Management Agreement that would
          increase fees the Fund pays to John Hancock for managing the Fund.

Q.  What is a multi-style and multi-manager approach? Why is it recommended for
the Growth & Income Fund?

A.  The multi-style and multi-manager approach combines different investment
styles, strategies and managers with the goal of producing more consistent
investment performance over market cycles. Performance consistency is considered
a primary goal of the Growth & Income Fund since its large cap equity strategy
makes this a core investment option for investors. The Board is recommending the
combination of two sub-advisors - IIA, the current sub-advisor, with Putnam
Investments ("Putnam"), a new sub-advisor -- to reduce the Fund's exposure to
the risk of any one manager or strategy being out of favor in certain market
environments.

Q.  Why Putnam?

A.  Putnam provides:

    .  a strong organization with the experience, significant resources and a
       well-defined investment process for the management of growth equity
       portfolios;
    .  an excellent long-term performance record and competitive sub-investment
       advisory fees in managing growth stock portfolios; and,
    .  a stellar reputation in the variable product marketplace and the
       potential for increased growth in Fund assets with it as the new sub-
       advisor.

Q.  Why the combination of IIA and Putnam?
<PAGE>

A.  IIA and Putnam have distinct and complementary investment approaches in
managing U.S. equity portfolios. The goal of combining these two managers is to
produce more consistent investment returns over market cycles.

Q.  Why is a change in the investment management fee recommended?

A.  The proposed fee increase is designed to account for the difference between
Putnam's fee schedule and that of the current sub-advisor; the additional
resources for fund administration, investment oversight and technology which the
multi-manager approach requires; and an adjustment to the investment management
fee paid to John Hancock -- which has remained the same since 1972 -- to
compensate for the significant increase since then in the complexity and cost of
managing and servicing the Fund.

Q.  How will the investment management fee be modified?

A.  The Board is recommending an increase in the annual percentage rates that
are applied to different levels of Fund assets to determine the amount the Fund
pays to John Hancock for investment management. Total fund expenses include
these investment management fees plus other non-advisory fund expenses (0.03% of
assets in 1999).

This means that if a shareholder had on average $10,000 in the Growth & Income
Fund during 1999 and the proposed fee structure had been in place for all of
1999, then the shareholder would have incurred about $42 in additional fund
expenses.

Q.  How will the Fund compare with similar funds in terms of total fund
expenses?

A.  The current expense ratio (total expenses divided by Fund assets) for the
Fund is far below the average expense ratio for comparable funds within the
variable insurance products marketplace having similar investment focus. Even
after the proposed modification, the Fund's expense will still be below the
average expense ratio for comparable funds.

Q.  How did the Board reach its conclusion to recommend this proposal?

A.  The Board, including the Independent Trustees in consultation with
independent counsel to the Trust, requested and evaluated a variety of
information provided by John Hancock. The Board carefully considered a number of
factors that are highlighted in this Q & A and detailed in the proxy statement.
These factors include the Fund's competitive performance and the increased
complexity and commitment of resources required by John Hancock in managing and
servicing the fund. After thorough study, the Board concluded that the new
management fee arrangements were fair and reasonable and would provide John
Hancock with the necessary financial incentives to promote the Fund within its
variable insurance products.

Q. How will you benefit from all of this?
<PAGE>

A.  As a shareholder, you will benefit from the multi-manager approach and gain
access to the investment expertise of Putnam Investments, an investment manager
with significant investment resources and a strong record of performance. In
addition, the increased fees will enable John Hancock to continue to dedicate
additional personnel and resources to the Fund, oversee a more complex
multi-manager investment approach and promote the Fund within its variable
insurance products.

Q.  What is the Board's recommendation regarding the modifications in
Proposals 2A-2C?

A.  The Board unanimously recommends that you vote "FOR" Proposal 2A-2C.

                              Growth & Income Fund


Proposal 2D:  Non-Diversified Status
--------------------------------------------------------------------------------

Q.  Why is "non-diversified" status being recommended for the Growth & Income
Fund?

A.  As a diversified fund, the Growth & Income Fund is restricted to investing a
maximum of 5% in a single issuer with respect to 75% of the Fund's total assets.
In a multi-manager structure, using two separate and distinct investment
strategies could potentially cause the overall Fund to exceed those limits. In
addition, the markets have evolved such that many individual issuers represent
close to or more than 5% of the overall market or appropriate equity market
benchmark. Therefore, "non-diversified" status will provide the necessary
flexibility for each sub-advisor to implement its investment strategy within a
multi-manager framework.


Q.  Will this increase the risk of investing in this Fund?

When it is exercised, non-diversified status presents the potential risk of
higher issuer concentration. However, the Fund will maintain overall risk
control and diversification through, among other things, diversity of managers,
number of securities, sector exposures and exposure to top 10 holdings.

Q.  What is the Board's recommendation regarding the modifications in
Proposal 2D?

A.  The Board unanimously recommends that you vote "FOR" Proposal 2D.

                              Growth & Income Fund



Proposal 2E:  Use of Restricted Securities
--------------------------------------------------------------------------------

Q.  Why is the Board recommending that the Growth & Income Fund be permitted to
use "restricted" securities?

A. The Board is recommending that the use of "restricted" securities, including
Rule 144A securities, be permitted to bring the Growth & Income Fund in line
with similar practices of other funds in the Trust and in the industry. The
growing market in "restricted" securities has expanded the Fund's investment
opportunities beyond those available to the Fund when its investment
restrictions were first put in place.


Q.  Will this action increase the risk of investing in this Fund?

A.  Because we expect the Fund to use this flexibility to invest primarily in
liquid 144A securities, the proposed change is not expected to significantly
change the risk profile of the Fund.

Q.  What is the Board's recommendation regarding the modifications in Proposal
2E?

A.  The Board unanimously recommends that you vote "FOR" Proposal 2E.

                              Growth & Income Fund


PROPOSAL 2F:   Use of Financial Futures
--------------------------------------------------------------------------------

Q. Why is the Board recommending that the Growth & Income Fund be permitted to
use financial futures?

A. The Board is recommending that the use of financial futures be permitted to
bring the Growth & Income Fund in line with the practices of other funds in the
Trust and in the industry, where the use of financial futures has become
standard market practice. Currently, most of the other funds in the Trust are
permitted to invest in financial futures. These funds commonly use financial
futures as an efficient way of "equitizing" cash exposure, a technique by which
managers purchase equity index futures (e.g., S&P 500 Index futures) to
effectively manage cash flows into and out of a fund and maintain exposure to
the equity market consistent with the Fund's investment goals and strategies.

Q.  Will this increase the risk of investing in this Fund?

A.  We expect the Growth & Income Fund to use financial futures to a limited
extent and primarily to equitize cash exposure. Therefore, their use is not
expected to significantly change the Fund's risk profile.

Q.  What is the Board's recommendation regarding the modifications in Proposal
2F?

A.  The Board of Trustees unanimously recommends that you vote "FOR" Proposal
2F.

                                Active Bond Fund

PROPOSAL 3A - 3B:  New Investment Management Agreement
--------------------------------------------------------------------------------

Q.  What modifications to the investment management agreements are being
proposed for the Active Bond Fund?

A.  The Board unanimously approved, and is recommending that shareholders
approve, amendments to the Sub-Investment Management Agreement and the
Investment Management Agreement that would increase fees that John Hancock pays
to the sub-investment manager and increase fees that the Trust pays to John
Hancock for management of the Active Bond Fund.

Q.  Why is this change being proposed?

A.  John Hancock's current fee schedule has remained the same since the early
1970s (1972). Also, the Fund has delivered excellent long-term performance with
below average risk under the current sub-advisor (John Hancock Advisers). The
proposed fee reflects a new sub-advisory fee schedule and an adjustment to the
investment management fee paid to John Hancock to compensate for the significant
increase in the complexity and cost of managing and servicing the Fund since the
fees were first established.

Q.  How will the investment management fee be modified?

A.  The Board is recommending an increase in the annual percentage rates that
are applied to different levels of Fund assets to determine the amount the Fund
pays to John Hancock for investment management. Total fund expenses include
these investment management fees plus other non-advisory fund expenses (0.03% of
assets in 1999).

This means that if a shareholder had on average $10,000 in the Active Bond Fund
during 1999 and the modification being proposed had been in place for all of
1999, then the shareholder would have incurred about $36 in additional fund
expenses.

Q.  How will the Fund compare with similar funds in terms of total fund
expenses?

A.  The current expense ratio (total fund expenses divided by Fund assets) is
far below the average expense ratio for comparable funds within the variable
insurance products marketplace having similar investment focus. Even after the
proposed modification, the expense ratio for the Fund will still be below the
average expense ratio for comparable funds.

Q.  How did the Board reach its conclusion to recommend this proposal?

A.  The Board, including the Independent Trustees in consultation with
independent counsel to the Trust, requested and evaluated a variety of
information provided by John
<PAGE>

Hancock. The Board carefully considered a number of factors that are highlighted
in this Q & A and detailed in the proxy statement. These factors include the
Fund's excellent performance and the increased complexity and commitment of
resources required by John Hancock in managing and servicing the fund. After
thorough study, the Board concluded that the new management fee arrangements
were fair and reasonable and would provide John Hancock with the necessary
financial incentives to promote the Fund within its variable insurance products.

Q.  How will you benefit from this?

A. As a shareholder, you will benefit from the expertise of the current sub-
advisor and its strong performance track record. In addition, the increased fees
will enable John Hancock to continue to dedicate additional personnel and
resources to the Fund and promote the Fund within its variable insurance
products, thereby increasing the Fund's opportunities for asset growth.

Q. What is the Board's recommendation regarding the modifications in Proposal
3A - 3B?

A. The Board of Trustees unanimously recommends that you vote "FOR" Proposal
3A - 3B.
<PAGE>

Small Cap Value, Global Balanced & Global Bond Funds

PROPOSAL 4A - 4B:  New Investment Management Agreements
--------------------------------------------------------------------------------

Q.  What modifications to the investment management agreements are being
proposed for the Small Cap Value, Global Balanced and Global Bond Funds?

A.  The Board unanimously approved, and is recommending that shareholders
approve, the following:

     (1)  a new Sub-Investment Management Agreement with Capital Guardian for
          the Small Cap Value, Global Balanced and Global Bond Funds reflecting
          a new sub-advisor to replace the three existing sub-advisors; and,

     (2)  a related amendment to the Investment Management Agreement that would
          increase fees the Trust pays to John Hancock for managing these funds.

Q.  Why is a new sub-advisor recommended for the Small Value Cap, Global
Balanced and Global Bond Funds?

A.  John Hancock's goal is to improve the investment performance of these Funds
and to form a strategic partnership with a leading investment manager in the
variable insurance marketplace.

Q.  Why Capital Guardian?

A.  Capital Guardian provides:

 .    a strong organization with the experience, significant resources and a
     well-defined investment process for the management of small cap equity,
     global balanced and global bond strategies;
 .    an excellent long-term performance record and competitive sub-investment
     advisory fees in managing small cap equity, global balanced and global bond
     portfolios; and,
 .    a premier reputation in the variable insurance marketplace and the
     potential for increased growth in Fund assets with it as the new
     sub-advisor.

Q.  Why are the changes to the investment management fees recommended?

A.  The proposed fee increases reflect the higher fees of the new sub-advisor
and the increasing complexity and costs attributable to John Hancock's
investment management activities on behalf of these Funds. The fee modification,
as proposed, is designed to compensate John Hancock for these increased costs.

Q.  How will the investment management fees be modified?

A.  The Board is recommending an increase in the annual percentage rates that
are applied to different levels of Fund assets to determine the amount the Fund
pays to John Hancock for investment management. Total fund expenses include
these investment management fees plus other non-advisory fund expenses (capped
at 0.10% of assets).
<PAGE>

This means that if a shareholder had on average $10,000 in one of these Funds
during 1999 and the modification being proposed had been in place for all of
1999, then the shareholder would have incurred about $10 to $20 in additional
fund expenses (depending on which Fund the shareholder was invested in).

Q.  How will these Funds compare with similar funds in terms of total fund
expenses?

A.  The current expense ratios (total fund expenses divided by fund assets) for
the Small Cap Value, Global Bond and Global Balanced Funds are below the average
expense ratios for comparable funds within the variable insurance products
marketplace having a similar investment focus and asset size. After the proposed
modifications, the expense ratio of the Small Cap Value Fund will be only
slightly above the comparable fund average while the expense ratios for the
Global Balanced and Global Bond Funds will still be below the average expense
ratios of comparable funds.

Q.  How did the Board reach its conclusion to recommend this proposal?

A.  The Board, including the Independent Trustees in consultation with
independent counsel to the Trust, requested and evaluated a variety of
information provided by John Hancock. The Board carefully considered a number of
factors that are highlighted in this Q & A and detailed in the proxy statement.
These factors include the increased complexity and commitment of resources
required by John Hancock in managing and servicing these funds. After thorough
study, the Board concluded that the new management fee arrangements were fair
and reasonable and would provide John Hancock with the necessary financial
incentives to promote the Funds within its variable insurance products.

Q.  How will you benefit from all this?

A.  As a shareholder, you will gain access to the investment talent and
expertise of Capital Guardian, an investment manager with significant investment
resources and a strong performance record. In addition, the increased fees will
enable John Hancock to continue to dedicate additional personnel and resources
to the Funds and promote the Funds within its variable insurance products,
thereby increasing opportunities for asset growth.

Q.  What is the Board's recommendation regarding the modifications in Proposal
4A -4B?

A.  The Board unanimously recommends that you vote "FOR" Proposal 4A - 4B.

                                 PROXY STATEMENT
                                     GENERAL

       This statement is furnished in connection with the solicitation of voting
instructions by the management of John Hancock Variable Series Trust I (the
"Trust") for use at the Special Meeting of its Shareholders (the "Meeting"), to
be held at the offices of John Hancock Life Insurance Company ("John Hancock"),
197 Clarendon Street, Boston, Massachusetts 02117, on Friday, October 20, 2000
at 11:00 A.M. Boston time. This solicitation is being made of all shares of
several series (the "Funds") of the Trust which are attributable to the
Shareholders' interests in John Hancock Variable Life Accounts U, V, and S; John
Hancock Variable Annuity Accounts U, V, JF, H and I; Separate Account IPL-1 of
Investors Partner Life Insurance Company ("IPL"); and John Hancock Mutual
Variable Life Insurance Account UV (collectively, the "Accounts"). The cost of
printing and mailing this notice and statement and the accompanying voting
instructions form will be borne by the Funds. All other expenses will be borne
by John Hancock. In addition to solicitations by mail, a number of regular
employees of John Hancock may solicit voting instructions in person or by
telephone; such employees will not be compensated for such services.
Solicitation materials were first made available to Shareholders on or about
September 13, 2000.

      Only the Funds indicated in the chart on the attached notice will vote on
each proposal listed in that chart. Where the chart shows more than one Fund as
voting on a particular proposal, approval by any Fund will be effective as to
that Fund, even if one or more other Funds fail to approve the proposal.

      THE TRUST WILL FURNISH, WITHOUT CHARGE, A COPY OF ITS ANNUAL REPORT FOR
1999 AND WHEN AVAILABLE A COPY OF ITS MOST RECENT SEMI-ANNUAL REPORT FOR 2000 TO
ANY SHAREHOLDER UPON REQUEST. SUCH REQUEST MAY BE MADE BY MAIL OR BY TELEPHONE,
USING THE ADDRESS OR TOLL-FREE TELEPHONE NUMBER SHOWN ON THE COVER OF THIS PROXY
STATEMENT.

Voting Instructions

      Although John Hancock and its subsidiaries, IPL and John Hancock Variable
Life Insurance Company ("JHVLICO"), through the Accounts, legally own all of the
Trust's shares, they will vote all of such shares in accordance with
instructions given by owners of variable life insurance policies and variable
annuity contracts, as discussed below. For this purpose, the owner of a variable
annuity contract during the period after annuity payments have commenced is the
annuitant.

      Any authorized voting instructions will also be valid for any adjournment
of the meeting and will be revocable only at the direction of the Shareholder
executing them. If an insufficient number of affirmative votes are obtained to
approve any item, the meeting may be adjourned to permit the solicitation of
additional votes. Shares will be voted for any such adjournment in the
discretion of those persons named in the voting instructions. Whether a proposal
is approved depends upon whether a sufficient number of votes are cast for the
proposal. Accordingly, an instruction to abstain from voting on any proposal has
the same practical effect as an instruction to vote against that proposal.

      Any person giving voting instructions may revoke them at any time prior to
their exercise by submitting a superseding voting instruction form or a notice
of revocation to the Trust. In addition, although mere attendance at the meeting
will not revoke voting instructions, a Shareholder present at the meeting may
withdraw his/her voting instruction form and vote in person. John Hancock,
JHVLICO and IPL will vote Trust shares in accordance with all properly executed
and unrevoked voting instructions received in time for the meeting.

       John Hancock, JHVLICO and IPL will vote the Trust shares of each Fund
held in their respective Accounts which are attributable to the policies and
contracts in accordance with the voting instructions received from the
Shareholders participating in that Fund. An Account's shares in any Fund which
are not attributable to policies or contracts or for which no timely voting
instructions are received will be represented and voted by John Hancock, JHVLICO
or IPL in the same proportion  as the voting instructions


<PAGE>

which are received from all Shareholders participating in the Fund through that
Account. Fund shares which are not attributable to policies and contracts
include shares purchased with contributions made as "seed money" to the
Portfolios, by John Hancock or JHVLICO.

      Please refer to Appendix A to this statement if you wish additional
information about the number of shares of each Fund that are outstanding or that
are attributable to John Hancock or JHVLICO (rather than to Shareholders).

Majority Voting

      In order for the shareholders of any Fund to approve any of the proposals
in this statement, the proposal must receive the favorable vote of a majority of
the outstanding shares of that Fund. When used in this information statement, a
"majority vote of the outstanding voting shares" means the affirmative vote of
more than 50% of the outstanding shares or, if it is less, 67% or more of the
shares present or represented at the meeting.


     WHETHER OR NOT YOU EXPECT TO BE PRESENT AT THE MEETING, PLEASE COMPLETE AND
RETURN THE ENCLOSED FORM OF VOTING INSTRUCTIONS. THERE WILL BE MAILED TO YOU A
VOTING INSTRUCTION FORM FOR EACH FUND YOU ARE USING. PLEASE COMPLETE AND RETURN
ALL FORMS. YOU MAY STILL VOTE IN PERSON IF YOU ATTEND THE MEETING.

                     PROPOSALS 1A, 1B and 1C - MANAGED FUND

              APPROVAL OF NEW SUB-INVESTMENT MANAGEMENT AGREEMENTS
         AND AN AMENDMENT TO THE CURRENT INVESTMENT MANAGEMENT AGREEMENT
                              FOR THE MANAGED FUND

      At its July 14, 2000 meeting, the Board of Trustees unanimously approved,
and voted to recommend that Shareholders approve, two new "multi-manager"
Sub-Investment Management Agreements and a related amendment to the Investment
Management Agreement that would increase fees payable by the Trust to John
Hancock for management of the Managed Fund. Shareholders will need to approve
all three Proposals to implement the change to a multi-manager approach.

Reasons for these Proposals

      The multi-manager Sub-Investment Management Agreements, and a related
amendment to the Investment Management Agreement for the Managed Fund, are being
submitted for shareholder approval at the Meeting. All three agreements must be
approved by Shareholders before any of them can go into effect.

The Sub-Investment Management Agreements

      Currently, John Hancock contracts with IIA to make investment decisions,
place investment orders, and provide certain record keeping functions for all
invested assets of the Managed Fund. That agreement was last approved by
Shareholders on February 12, 1986.

      In providing investment advisory services to the Trust, John Hancock has
observed the following with respect to certain funds of the Trust, in particular
the Managed Fund:

     .    Investment managers often have very unique approaches and
          expertise in managing investments within the same asset class or
          investment category.

     .    Different investment strategies and managers produce different
          investment results in different market environments - with no single
          approach consistently outperforming others over extended periods.

     .    Even strong managers with sound and disciplined approaches and
          strategies will move out of favor in certain market environments.

      These observation have led John Hancock to seek to implement a
multi-manager approach for the Managed Fund by selecting two sub-investment
managers that employ distinct investment strategies in the management of
domestic balanced portfolios. The desired goal is to produce more consistent
investment returns over market cycles. By combining different and complementary
investment strategies, the multi-manager approach seeks to reduce the Managed
Fund's exposure to the risk of any one manager or strategy going out of favor in
certain market environments. Performance consistency is considered an important
goal for the Managed Fund since its broad-based balanced strategy makes this a
core investment option for investors.

      IIA, the current sub-investment manager to the Managed Fund, seeks to add
value primarily by focusing its strategy on individual stock and bond selection.
IIA's investment approach for the Managed Fund:

     .    has a normal target mix of 60% stocks and 40% bonds;

     .    selects stocks and bonds using a combination of proprietary equity
          research and quantitative tools;

     .    focuses on large cap stocks that are undervalued relative to the
          stock's history and have improving earnings growth prospects;

     .    invests broadly across fixed income sectors and selects bonds believed
          to be attractively priced and offer cheap, predictable cash flow;

<PAGE>

     .    uses a team approach in making investment decisions, with the lead
          portfolio managers responsible for implementation of the team's
          investment strategy; and,

     .    employs risk control techniques to maintain risk and industry
          characteristics similar to the overall market.

      IIA's investment approach has resulted in overall average risk and returns
relative to comparable domestic balanced funds, with periods of underperformance
in volatile and momentum-driven market environments. These market environments
proved challenging for most investment managers with a quantitative approach
that is sensitive to valuation characteristics. As a result, John Hancock
decided to select an additional sub-investment manager that would implement a
complementary and distinct investment approach in the management of domestic
balanced portfolios.

     Among the factors that John Hancock and the Board of Trustees considered in
selecting an additional sub-investment manager were the following:

     .   Strong organization with experience and significant resources
         (investment and operations personnel) dedicated to the development and
         management of domestic balanced portfolios.

     .    Disciplined and well-defined investment process for investing in
          stocks and bonds.

     .    Strong long-term performance record in managing domestic balanced
          portfolios.

     .    Sub-investment advisory fee that is competitive relative to other
          domestic balanced portfolios.

     .    The degree to which the investment manager's historical and expected
          investment returns are correlated with those of IIA.

     .    The sub-investment manager's reputation and presence in the variable
          products marketplace and the sub-investment manager's potential for
          increasing the growth in Fund assets.

After evaluating potential sub-investment managers based on these criteria, John
Hancock recommended to the Board of Trustees, and the Board unanimously
approved, that Capital Guardian be retained as a complementary manager for the
Managed Fund.

      Capital Guardian seeks to add value by focusing its strategy on individual
stock and bond selection. Capital Guardian's investment approach:

     .    would have a normal target of 70% stocks and 30% bonds;

     .    selects stocks and bonds using a fundamental, bottom-up, research
          driven approach;

     .    focuses on large and mid cap stocks that have attractive valuations
          relative to long-term growth prospects and asset-rich companies with
          strong balance sheets;

     .    invests broadly across undervalued fixed income sectors and
          securities;

     .    employs a multiple-manager approach by which each portfolio manager
          and the research analysts as a group each manage a separate portion of
          the portfolio to capture the highest conviction ideas of the
          investment team; and,

     .    achieves risk control and diversification through the diversity of
          independent ideas of each portfolio manager and research analyst.

     The multi-manager approach for the Managed Fund - combining the investment
expertise of both IIA and Capital Guardian - seeks to provide investors with
diversification of investment strategies and the potential for more consistent
investment returns over market cycles.

     On or about November 1, 2000, the then-existing assets of the Fund will be
allocated between IIA and Capital Guardian. Capital Guardian will receive $500
million and IIA will receive the remainder. Based upon total Fund assets as of
June 30, 2000, this would result in an allocation of approximately 85% to IIA
and 15% to Capital Guardian. After November 1, 2000, investments in the Fund
will be allocated equally between the two sub-advisors while redemptions will be
allocated on asset-weighted basis. Such allocation methodology could be changed
in the future, but there is no present intention of doing so.

     The sub-investment advisory fee to be charged by Capital Guardian under its
new Sub-Investment Management Agreement is higher than that charged by IIA and
recognizes, among other things, the greater degree of resources and analysis
required of Capital Guardian in implementing a more fundamental, research-driven
approach. Whereas John Hancock will pay IIA a sub-investment advisory fee at an
annual rate of 0.30% on the first $500 million of assets managed by IIA, 0.2625%
on the next $500 million

<PAGE>

managed by IIA and 0.2250% on any additional amounts managed by IIA, John
Hancock will pay Capital Guardian 0.50% for the first $150 million managed by
Capital Guardian, 0.45% for the next $150 million managed by Capital Guardian,
0.30% for the next $200 million managed by Capital Guardian, and 0.25% for any
additional amounts managed by Capital Guardian. The sub-investment advisory fee
for IIA will remain at the rate in effect prior to November 1, 2000.

     The proposed forms of the "multi-manager" Sub-Investment Management
Agreements are included as Appendix B-1 to this statement. The agreements with
IIA and Capital Guardian are substantially similar except with respect to the
rate of sub-advisory fees. As stated in the agreements, John Hancock will pay
all sub-advisory fees to the sub-investment managers. Therefore, any increase in
the sub-advisory fees need not necessarily result in any additional charge to
the Trust or to Shareholders. However, in this case the higher fees payable to
Capital Guardian will be reflected in the proposed increase to the investment
advisory fee to be paid by the Trust to John Hancock.

The Current Investment Management Agreement and Proposed Amendment

     Pursuant to its Investment Management Agreement with the Trust dated April
12, 1988, John Hancock advises the Trust in connection with policy decisions of
the Managed Fund; provides administration of day-to-day operations; provides
personnel, office space, equipment and supplies for the Fund; maintains records
required by the Investment Company Act of 1940; supervises activities of the
sub-investment managers referred to above; and supervises the activities of the
other providers of services to the Fund. That agreement was last approved by the
Shareholders on April 23, 1999.

     For any fiscal year in which the normal operating costs and expenses of the
Managed Fund, exclusive of the investment advisory fees, interest, brokerage,
commissions, taxes and extraordinary expenses outside the control of John
Hancock exceed 0.10% of that Fund's average daily net assets, the current
Investment Management Agreement provides that John Hancock will reimburse that
Fund promptly after the end of the fiscal year in an amount equal to such
excess. There was no reimbursement payable to the Managed Fund for the period
ended December 31, 1999.

     Under the current Investment Management Agreement, John Hancock is paid a
fee at the annual rate of 0.40% for the first $500 million of the Managed Fund's
average daily net assets; 0.35% for the next $500 million and 0.30% for any
additional amounts.

     After evaluating the fees to be charged to the Managed Fund for a
multi-manager approach, taking into account the cost of services to be rendered
by John Hancock and fees charged by the sub-investment managers, John Hancock
recommended to the Board of Trustees at its July 14, 2000 meeting that the
current Investment Management Agreement be amended to reflect an increase in the
Fund's investment advisory fees to 0.74% for the first $500 million of the
Fund's average daily net assets; 0.68% for the next $500 million, and 0.650% for
any additional amounts. At each of those levels, total expenses (i.e., advisory
fees plus other fund expenses capped as previously noted) would be 0.03% higher
(based upon 1999 expenses). If the increase had been in effect during 1999, (i)
the Trust would have paid John Hancock $22,352,466.00 on behalf of the Managed
Fund, rather than the $10,789,553.00 paid under the current Investment
Management Agreement (a 107.2% increase), and (ii) the ratio of total expenses
to average daily net assets would have been 0.70% rather than 0.35%. However,
0.70% ratio compares favorably with the total expense ratio incurred by funds
that support other variable insurance products and that have similar investment
focus and asset characteristics. The average total expense ratio for all such
funds is 0.72%. The foregoing analysis is based upon a study prepared for the
Board by John Hancock using data collected by Morningstar, Inc., an independent
statistical service that tracks expense data on variable insurance funds. See
the table in Appendix A-1 for a tabular comparison of the actual expense ratios
                                -------
for 1999 with expense ratios that would have been produced by the proposed
modifications had they been in effect during 1999.

     In all other respects, the current Investment Management Agreement, as
described in Appendix C to this statement, will remain unchanged.

<PAGE>

Rationale For Proposed Changes In Management Fees

     After conducting a complete review of the level of investment management
fees for balanced funds in general, John Hancock noted the following:

     .    Since the Managed Fund's inception, there has been a substantial
          increase in the commitment of qualified personnel, resources and
          sophisticated information systems and technology by John Hancock to
          support its increasingly complex investment management activities on
          behalf of the Trust.

     .    The multi-manager approach will further increase the complexity of
          John Hancock's oversight and administration, requiring increased
          resources and oversight for Fund administration, investments, and
          technology.

     .    The current investment management fee levels of the Fund (established
          in the mid-1980's) are far below the average contractual fee levels
          for other mutual funds within the variable insurance products
          marketplace having similar investment focus and asset characteristics.

John Hancock wished to establish a new fee schedule for the Fund that would:

     .    remain competitive with other funds in the current variable insurance
          products marketplace having a similar investment focus and asset
          characteristics;

     .    provide appropriate financial incentives, within the current
          competitive environment, to support John Hancock's increased
          allocation of personnel and resources to the Fund; and

     .    provide appropriate financial incentives to support the increased
          resources and complexity for overseeing a multi-manager investment
          approach; and

     .    provide a level of financial incentive that would make it easier for
          John Hancock to include the Fund as an investment option in its new
          insurance products.

     As a result of this review and analysis, John Hancock discussed with the
Board the changing nature of compensation in the variable insurance marketplace
and John Hancock's position relative to marketplace trends in pricing. At the
July 14, 2000 Board Meeting, the full Board met to review and consider John
Hancock's proposed recommendation to implement a new investment management fee
schedule for the Fund.

Basis For The Trustees' Recommendation

     At a meeting held on July 14, 2000, the Board of Trustees, including all
the Trustees who are not "interested persons" of the Managed Fund (the
"Independent Trustees"), unanimously approved a modified management fee schedule
for the Fund. The Board is proposing that Shareholders approve an Amended and
Restated Investment Management Agreement between the Trust and John Hancock
("New Management Agreement") in order to modify the current investment
management fee schedule. The proposed new schedule of investment management fee
rates for the Managed Fund is as stated above.

     In evaluating and approving the New Management Agreement, the Board,
including the Independent Trustees and in consultation with independent counsel
to the Trust, requested and evaluated information provided by John Hancock
which, in the Board's opinion, constituted all the information reasonably
necessary for the Board to form a judgment as to whether the New Management
Agreement and management fee structure would be in the best interests of the
Managed Fund and its Shareholders.

     In making its decision to approve the modified management fee schedule, the
Board considered, among other factors, the following:

     .    The comparability of the investment management fees and other expenses
          that would be paid by the Fund under the New Management Agreement to
          those paid to other funds within the current variable insurance
          marketplace having similar investment focus and asset characteristics.

     .    The increased commitment of personnel and resources required of John
          Hancock, since the inception of the Fund, to support the investment
          management services provided to the Fund, and

<PAGE>

          the increased sophistication of the investment evaluation and
          monitoring process used by John Hancock on behalf of the Fund.

     .    The significantly increased commitment required of John Hancock to
          actively oversee the multi-manager approach being recommended for the
          Fund, particularly the increased resources for investment oversight,
          fund administration and technology.

     .    The expected benefits to the Fund of the new multi-manager approach.

     .    The impact of the proposed changes in investment management fee rates
          and changes in other expenses of the Fund on the Fund's total expense
          ratio.

     .    The historical investment record of John Hancock in managing the Fund,
          as well as performance information regarding other funds within the
          current variable insurance marketplace not advised or managed by John
          Hancock but having similar investment focus and asset types.

     .    The Board's favorable evaluation of the nature, quality and breadth of
          investment management services provided by John Hancock to the Fund
          over the years.

     .    Current and projected profits to John Hancock, both under the current
          investment management fee schedule and the proposed new investment
          management fee schedule, from providing investment management services
          to the Trust and from the John Hancock insurance products which use
          the Trust as a funding medium.

     .    The need to provide sufficient revenues to John Hancock, within the
          competitive marketplace, to promote the Fund as a funding medium for
          variable insurance products it may market in the future.

     Based upon all of the above factors, the Board (including the Independent
Trustees) determined that the new management fee arrangement proposed by John
Hancock was fair, reasonable and in the best interests of the Fund and its
Shareholders.

                           PROPOSAL 1D - MANAGED FUND

   APPROVAL OF CLASSIFICATION OF THE MANAGED FUND AS A "NON-DIVERSIFIED" FUND

At its July 14, 2000 meeting, the Board of Trustees also unanimously approved,
and voted to recommend that Shareholders approve, John Hancock's recommendations
to change the classification of the Managed Fund from "diversified" to "non-
diversified".

Discussion

     A current investment policy of the Managed Fund requires the Fund to be
"diversified."/1/ This requirement is satisfied if at least 75 % of the market
value of the Fund's total assets is invested in cash and cash items (including
receivables), Government securities, securities of other investment companies,
and other securities. For purposes of this calculation, investments with respect
of any one issuer (other than investments in the United States Government or its
agency or instrumentality) are limited to an amount not greater in value than 5%
of the value of the total assets of such issuer and to not more than 10% of the
outstanding voting securities of such issuer.

     In general, "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. The value of a
non-diversified 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
because a relatively high percentage of a non-diversified fund's assets may be
invested in the obligations of a limited number of issuers. Most of the funds of
the Trust are "diversified.

     In making its recommendation, John Hancock noted that "non-diversified"
status would provide necessary flexibility for each sub-investment manager of
the Managed Fund to implement its investment strategy within the multi-manager
framework. The implementation of two distinct investment strategies could
potentially result in the overall Fund exceeding diversification limits. John
Hancock also noted that the domestic equity market has evolved such that a
significant number of individual issuers represent close to or more than 5% of
the relevant market or appropriate equity market benchmark. Therefore, it has
become increasingly difficult for certain funds of the Trust to remain
"diversified" and still follow their investment strategies and make active bets
relative to their benchmarks.

Trustees' Recommendation

     The Board of Trustees believes that the proposed change of the Managed
Fund's classification to "non-diversified", and the corresponding modification
of the Fund's investment policy, is in the best interests of the Shareholders of
the Fund.



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

/1/ Fundamental policy (10) of the Trust provides that a Fund shall not 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 does not currently apply
to the Large Cap Aggressive Growth, Mid Cap Growth or Global Balanced Funds. In
addition, Proposals to be voted upon at a September 28, 2000 shareholder meeting
seek approval for the Large Cap Growth, Real Estate Equity and Global Bond Funds
to be added to the list of Funds to which the restriction does not apply. The
Growth & Income Fund is also proposed to be classified as "non-diversified"
under Proposal 2D in this statement.

                 PROPOSALS 2A, 2B and 2C -- GROWTH & INCOME FUND

  APPROVAL OF NEW SUB-INVESTMENT MANAGEMENT AGREEMENTS AND AN AMENDMENT TO THE
      CURRENT INVESTMENT MANAGEMENT AGREEMENT FOR THE GROWTH & INCOME FUND

     At its July 14, 2000 meeting, the Board of Trustees unanimously approved,
and voted to recommend that Shareholders approve, two new "multi-manager"
Sub-Investment Management Agreements and a related amendment to the Investment
Management Agreement that would increase fees payable by the Trust to John
Hancock for management of the Growth & Income Fund. Shareholders will need to
approve all three Proposals to implement the change to a multi-manager approach.

Reasons for these Proposals

     The multi-manager Sub-Investment Management agreements, and a related
amendment to the Investment Management Agreement for the Growth & Income Fund,
are being submitted for shareholder approval at the Meeting. All three
agreements must be approved by Shareholders before any of them can go into
effect.

The Sub-Investment Management Agreements

     Currently, John Hancock contracts with IIA to make investment decisions,
place investment orders, and provide certain record keeping functions for all
invested assets of the Growth & Income Fund. That agreement was last approved by
Shareholders on February 12, 1986.

     In providing investment advisory services to the Trust, John Hancock has
observed the following with respect to certain funds of the Trust, in particular
the Growth & Income Fund:
     .    Investment managers often have very unique approaches and expertise in
          managing investments within the same asset class or investment
          category.
     .    Different investment styles and managers produce different investment
          results in different market environments - with no single style or
          approach consistently outperforming others over extended periods.
     .    Even strong managers with sound and disciplined approaches and
          strategies will move out of favor in certain market environments.

     These observations have led John Hancock to seek to implement a
multi-manager approach for the Growth & Income Fund by selecting two
sub-investment managers that employ distinct investment strategies in the
management of domestic equity portfolios. The desired goal is to produce more
consistent investment returns over market cycles. By combining different and
complementary investment strategies, the multi-manager approach seeks to reduce
the Growth & Income Fund's exposure to the risk of any one manager or strategy
going out of favor in certain market environments. Performance consistency is
considered an important goal for the Growth & Income Fund since its broad equity
strategy of investing in large cap stocks makes this a core investment option
for investors.

     IIA, the current sub-investment manager to the Growth & Income Fund, seeks
to add value primarily by focusing its strategy on individual stock selection.
IIA's investment approach for the Growth & Income Fund:
     .    focuses on large cap stocks that are undervalued relative to the
          stock's history and have improving earnings growth prospects;
     .    selects stocks using a combination of proprietary equity research and
          quantitative tools;
     .    uses a team approach in making investment decisions, with the lead
          portfolio managers responsible for implementation of the team's
          investment strategy; and,
     .    employs risk control techniques to maintain risk and industry
          characteristics similar to the Fund's benchmark.
<PAGE>

IIA's investment approach has resulted in overall average risk and returns
relative to comparable domestic equity funds, with periods of underperformance
in volatile and momentum-driven market environments. These market environments
proved challenging for most investment managers with a quantitative approach
that is sensitive to valuation characteristics. As a result, John Hancock
decided to select an additional sub-investment manager that would implement a
complementary and distinct investment approach in the management of equity
portfolios.

     Among the factors that John Hancock and the Board of Trustees considered in
selecting an additional sub-investment manager were the following:
      .   Strong organization with experience and significant resources
          (investment and operations personnel) dedicated to the development and
          management of growth style equity portfolios.
      .   Disciplined and well-defined investment process for investing in
          growth stocks.
      .   Strong long-term performance record in managing growth stock
          portfolios.
      .   Sub-investment advisory fee that is competitive relative to other
          growth stock portfolios.
      .   The degree to which the investment manager's historical and expected
          investment returns are correlated with those of IIA.
      .   The sub-investment manager's reputation and presence in the variable
          products marketplace and the sub-investment manager's potential for
          increasing the growth in Fund assets.
After evaluating potential sub-investment managers based on these criteria, John
Hancock recommended to the Board of Trustees, and the Board unanimously
approved, that Putnam be retained as a complementary manager for the Growth &
Income Fund.

     Putnam seeks to add value by focusing its strategy on individual stock
selection decisions. Putnam's investment approach:
      .   focuses on large and mid-size growth stocks;
      .   selects stocks using proprietary bottom-up, fundamental research and a
          systematic screening process;
      .   selects stocks with above-average potential for growth in revenues and
          earnings that meet screening criteria for earnings surprise and
          momentum, valuation and financial strength;
      .   uses a team approach in making investment decisions, with the lead
          portfolio managers responsible for implementation of the team's
          investment strategy; and,
      .   employs risk management tools and qualitative judgement to determine
          sector, industry and stock specific weightings and seeks broad
          industry sector diversification.

     The multi-manager approach for the Growth & Income Fund - combining the
investment expertise of both IIA and Putnam - seeks to provide investors with
diversification of investment strategies and the potential for more consistent
investment returns over market cycles.

     On or about November 1, 2000, the then-existing assets of the Fund will be
allocated between IIA and Putnam. Putnam will receive $1 billion and IIA will
receive the remainder. Based upon total Fund assets as of June 30, 2000, this
would result in an allocation of approximately 75% to IIA and 25% to Putnam.
After November 1, 2000, investments in the Fund will be allocated equally
between the two sub-advisors while redemptions will be allocated on an
asset-weighted basis. Such allocation methodology could be changed in the
future, but there is no present intention of doing so.

     The sub-investment advisory fee to be charged by Putnam under its new
Sub-Investment Management Agreement is higher than that charged by IIA and
recognizes, among other things, the greater degree of resources and analysis
required of Putnam in implementing a more fundamental, research-driven approach.
Whereas John Hancock will pay IIA a sub-investment advisory fee at an annual
rate of 0.1875% on all assets managed by IIA, John Hancock will pay Putnam 0.50%
for the first $150 million managed by Putnam; 0.45% for the next $150 million
managed by Putnam; and 0.35% for any additional amounts managed by Putnam. The
sub-investment advisory fee for IIA will remain at the rate in effect prior to
November 1, 2000.
<PAGE>

     The proposed forms of the "multi-manager" Sub-Investment Management
Agreements are included as Appendix B-2 to this statement. The agreements with
IIA and Putnam are substantially similar except with respect to the rate of sub-
advisory fees. As stated in the agreements, John Hancock will pay all sub-
advisory fees to the sub-investment managers. Therefore, any increase in the
sub-advisory fees need not necessarily result in any additional charge to the
Trust or to Shareholders. However, in this case the higher fees payable to
Putnam will be reflected in the proposed increase to the investment advisory fee
to be paid by the Trust to John Hancock.


The Current Investment Management Agreement and Proposed Amendment

     Pursuant to its Investment Management Agreement with the Trust dated April
12, 1988, John Hancock advises the Trust in connection with policy decisions of
the Growth & Income Fund; provides administration of day-to-day operations;
provides personnel, office space, equipment and supplies for the Fund; maintains
records required by the Investment Company Act of 1940; supervises activities of
the sub-investment managers referred to above; and supervises the activities of
the other providers of services to the Fund. That agreement was last approved by
the Shareholders on April 23, 1999.

     For any fiscal year in which the normal operating costs and expenses of
the Growth & Income Fund, exclusive of the investment advisory fees, interest,
brokerage, commissions, taxes and extraordinary expenses outside the control of
John Hancock exceed 0.10% of that Fund's average daily net assets, the current
Investment Management Agreement provides that John Hancock will reimburse that
Fund promptly after the end of the fiscal year in an amount equal to such
excess. There was no reimbursement payable to the Growth & Income Fund for the
period ended December 31, 1999.

     Under the current Investment Management Agreement, John Hancock is paid a
fee at the annual rate of 0.25% of the Growth & Income Fund's average daily net
assets.

     After evaluating the fees to be charged to the Growth & Income Fund for a
multi-manager approach, taking into account the cost of services to be rendered
by John Hancock and fees charged by the sub-investment managers, John Hancock
recommended to the Board of Trustees at its July 14, 2000 meeting, that the
current Investment Management Agreement be amended to reflect an increase in the
Fund's investment advisory fees to 0.71% for the first $150 million of the
Fund's average daily net assets; 0.69% for the next $150 million, and 0.67% for
any additional amounts. At each of those levels, total expenses (i.e., advisory
fees plus other fund expenses capped as previously noted) would be 0.03% higher
(based upon 1999 expenses). If the increase had been in effect during 1999, (i)
the Trust would have paid John Hancock $26,373,126.00 on behalf of the Growth &
Income Fund, rather than the $9,806,770.00 paid under the current Investment
Management Agreement (a 168.9% increase), and (ii) the ratio of total expenses
to average daily net assets would have been 0.70% rather than 0.28%. However,
the 0.70% ratio compares favorably with the total expense ratio incurred by
funds that support other variable insurance products and that have similar
investment focus and asset characteristics. The average total expense ratio for
all such funds is 0.78%. The foregoing analysis is based upon a study prepared
for the Board by John Hancock using data collected by Morningstar, Inc., an
independent statistical service that tracks expense data on variable insurance
funds. See the table in Appendix A-1 for a tabular comparison of the actual
                                           -------
expense ratios for 1999 with expense ratios that would have been produced by the
proposed modifications had they been in effect during 1999.

     In all other respects, the current Investment Management Agreement, as
described in Appendix C to this statement, will remain unchanged.
<PAGE>

Rationale For Proposed Changes In Management Fees

     After conducting a complete review of the level of investment management
fees for equity blend funds in general, John Hancock noted the following:
     .    Since the Growth & Income Fund's inception, there has been a
          substantial increase in the commitment of qualified personnel,
          resources and sophisticated information systems and technology by John
          Hancock to support its increasingly complex investment management
          activities on behalf of the Trust.
     .    The multi-manager approach will further increase the complexity of
          John Hancock's oversight and administration, requiring increased
          resources and oversight for Fund administration, investments, and
          technology.
     .    The current investment management fee levels of the Fund (established
          in 1972) are far below the average contractual fee levels for other
          mutual funds within the variable insurance products marketplace having
          similar investment focus and asset characteristics.

John Hancock wished to establish a new fee schedule for the Fund that would:
     .    remain competitive with other funds in the current variable insurance
          products marketplace having a similar investment focus and asset
          characteristics;
     .    provide appropriate financial incentives, within the current
          competitive environment, to support John Hancock's increased
          allocation of personnel and resources to the Fund; and
     .    provide appropriate financial incentives to support the increased
          resources and complexity for overseeing a multi-manager investment
          approach; and
     .    provide a level of financial incentive that would make it easier for
          John Hancock to include the Fund as an investment option in its new
          insurance products.

     As a result of this review and analysis, John Hancock discussed with the
Board the changing nature of compensation in the variable insurance marketplace
and John Hancock's position relative to marketplace trends in pricing. At the
July 14, 2000 Board Meeting, the full Board met to review and consider John
Hancock's proposed recommendation to implement a new investment management fee
schedule for the Fund.

Basis For The Trustees' Recommendation

     At a meeting held on July 14, 2000, the Board of Trustees, including all
the Trustees who are not "interested persons" of the Growth & Income Fund (the
"Independent Trustees"), unanimously approved a modified management fee schedule
for the Fund. The Board is proposing that Shareholders approve an Amended and
Restated Investment Management Agreement between the Trust and John Hancock
("New Management Agreement") in order to modify the current investment
management fee schedule. The proposed new schedule of investment management fee
rates for the Growth & Income Fund is as stated above.

     In evaluating and approving the New Management Agreement, the Board,
including the Independent Trustees and in consultation with independent counsel
to the Trust, requested and evaluated information provided by John Hancock
which, in the Board's opinion, constituted all the information reasonably
necessary for the Board to form a judgment as to whether the New Management
Agreement and management fee structure would be in the best interests of the
Growth & Income Fund and its Shareholders.

     In making its decision to approve the modified management fee schedule, the
Board considered, among other factors, the following:
     .    The comparability of the investment management fees and other expenses
          that would be paid by the Fund under the New Management Agreement to
          those paid to other funds within the current variable insurance
          marketplace having similar investment focus and asset characteristics.
<PAGE>

     .    The significantly increased commitment of personnel and resources
          required of John Hancock, since the inception of the Fund, to support
          the investment management services provided to the Fund, and the
          increased sophistication of the investment evaluation and monitoring
          process used by John Hancock on behalf of the Fund.
     .    The significantly increased commitment required of John Hancock to
          actively oversee the multi-manager approach being recommended for the
          Fund, particularly the increased resources for investment oversight,
          fund administration and technology.
     .    The expected benefits to the Fund of the new multi-manager approach.
     .    The impact of the proposed changes in investment management fee rates
          and changes in other expenses of the Fund on the Fund's total expense
          ratio.
     .    The historical investment record of John Hancock in managing the Fund,
          as well as performance information regarding other funds within the
          current variable insurance marketplace not advised or managed by John
          Hancock but having similar investment focus and asset types.
     .    The Board's favorable evaluation of the nature, quality and breadth of
          investment management services provided by John Hancock to the Fund
          over the years.
     .    Current and projected profits to John Hancock, both under the current
          investment management fee schedule and the proposed new investment
          management fee schedule, from providing investment management services
          to the Trust and from the John Hancock insurance products which use
          the Trust as a funding medium.
     .    The need to provide sufficient revenues to John Hancock, within the
          competitive marketplace, to promote the Fund as a funding medium for
          variable insurance products it may market in the future.

     Based upon all of the above factors, the Board (including the Independent
Trustees) determined that the new management fee arrangement proposed by John
Hancock was fair, reasonable and in the best interests of the Fund and its
Shareholders.

                           AS A "NON-DIVERSIFIED" FUND

     At its July 14, 2000 meeting, the Board of Trustees also unanimously
approved, and voted to recommend that Shareholders approve, John Hancock's
recommendations to change the classification of the Growth & Income Fund from
"diversified" to "non-diversified".

Discussion

     A current investment policy of the Growth & Income Fund requires the Fund
to be "diversified."/3/ This requirement is satisfied if at least 75% of the
market value of the Fund's total assets is invested in cash and cash items
(including receivables), Government securities, securities of other investment
companies, and other securities. For purposes of this calculation, investments
with respect of any one issuer (other than investments in the United States
Government or its agency or instrumentality) are limited to an amount not
greater in value than 5% of the value of the total assets of such issuer and to
not more than 10% of the outstanding voting securities of such issuer.

     In general, "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. The value of a
non-diversified 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
because a relatively high percentage of a non-diversified fund's assets may be
invested in the obligations of a limited number of issuers. Most of the funds of
the Trust are "diversified."

     In making its recommendation, John Hancock noted that "non-diversified"
status would provide necessary flexibility for each sub-investment manager of
the Growth & Income Fund to implement its investment strategy within the
multi-manager framework. The implementation of two distinct investment
strategies could potentially result in the overall Fund exceeding
diversification limits. John Hancock also noted that the domestic equity market
has evolved such that a significant number of individual issuers represent close
to or more than 5% of the relevant market or appropriate equity market
benchmark. Therefore, it has become increasingly difficult for certain funds of
the Trust to remain "diversified" and still follow their investment strategies
and make active bets relative to their benchmarks.

Trustees' Recommendation

     The Board of Trustees believes that the proposed change of the Growth &
Income Fund's classification to "non-diversified", and the corresponding
modification of the Fund's investment policy, is in the best interests of the
Shareholders of the Fund.

     THE BOARD OF TRUSTEES UNANIMOUSLY RECOMMEND THAT THE SHAREHOLDERS OF THE
GROWTH & INCOME FUND GIVE INSTRUCTIONS TO VOTE FOR THE APPROVAL OF
                                               ---
CLASSIFICATION OF THE FUND AS "NON-DIVERSIFIED."

                       PROPOSAL 2E -- GROWTH & INCOME FUND

   MODIFICATION TO THE INVESTMENT RESTRICTIONS OF THE GROWTH & INCOME FUND TO
   PERMIT INVESTMENTS IN SECURITIES THAT ARE SUBJECT TO LEGAL RESTRICTIONS ON
                                     RESALE

     At its July 14, 2000 meeting, the Board of Trustees also unanimously
approved, and voted to recommend that Shareholders approve, a change in the
investment restrictions of the Growth & Income Fund to allow the Fund to
purchase securities which are subject to legal or contractual delays in or
restrictions on resale (commonly referred to as "restricted securities"),
including those eligible for resale to qualified institutional buyers under Rule
144A of the Securities Act of 1933.

     If approved by Shareholders, the Growth & Income Fund would have authority
to invest in restricted securities, including Rule 144A securities for the
reasons and subject to the limitations set forth below.

Discussion

     As an open-end investment company, the Trust is limited in the amount of
illiquid securities that it may own because such securities may present problems
of accurate valuation, and it is possible that the Trust could have difficulty
satisfying redemptions within seven days as required under the Investment
Company Act of 1940. In general, an illiquid security is one which cannot be
sold in the ordinary course of business within seven days at approximately the
value at which the Trust has valued the security. Illiquid securities generally
include restricted securities.

     However, the securities markets are evolving. For example, the markets for
various types of securities are almost exclusively institutional. These
instruments are often either exempt from registration or sold in transactions
not requiring registration. Although these securities may be legally classified
as "restricted," institutional investors will often justifiably rely on an
efficient institutional market in which the unregistered security can be readily
resold. The fact that the securities may be restricted because of legal or
contractual restrictions on resale to the general public will, therefore, not be
dispositive of the liquidity of such investments.

     In 1990, the SEC adopted Rule 144A to provide a safe harbor from
registration under the 1933 Act for the resale of privately placed securities to
qualified buyers. Rule 144A has increased the efficiency and liquidity of the
U.S. private placement market. Issuers that qualify for reliance on the Rule now
have access to a larger sophisticated investor base composed of both traditional
private and public institutional investors. The size of Rule 144A issues is
larger than that of many traditional private placements.

     In general, the market in restricted securities expands the opportunities
beyond what was available to the Fund when the Fund's investment restrictions
were first put in place. Given the growth in this market and its improving
liquidity, John Hancock believes that the Fund should be allowed to buy
restricted securities, including 144A securities. John Hancock or the Fund's
sub-investment manager will in each case determine whether any such restricted
securities should be deemed to be illiquid. If so, those securities, plus any
other illiquid securities owned by the Fund, may not, at the time of purchase,
exceed 15% of the Fund's net assets.

Trustees' Recommendation

     The Board of Trustees believes that the proposed changes to the Growth &
Income Fund's investment restrictions is in the best interests of the
Shareholders of the Fund.

     THE BOARD OF TRUSTEES UNANIMOUSLY RECOMMEND THAT THE SHAREHOLDERS OF THE

                       PROPOSAL 2F -- GROWTH & INCOME FUND

        MODIFICATION TO INVESTMENT POLICIES TO PERMIT INVESTMENT BY THE
                   GROWTH & INCOME FUND IN FINANCIAL FUTURES

      At its July 14, 2000 meeting, the Board of Trustees also unanimously
approved, and voted to recommend that Shareholders of the Growth & Income Fund
approve, a change in the investment policies of the Trust to clearly allow the
Fund to purchase securities of a type commonly referred to as "financial
futures."

Discussion

      A current investment policy of the Trust permits 22 funds/5/ other than
the Growth & Income Fund to invest in "financial futures." The term is used to
describe interest rate futures contracts, stock index futures contracts, and
currency futures contracts. Funds that invest in financial futures are also
generally authorized to buy and sell options on these 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 and 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 a
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.

      The writer of an option on a financial futures contract agrees either to
buy or sell a financial futures contract at a specified price, if the purchaser
exercises the option and thereby assumes the opposite position in the financial
futures contract. A "put" option obligates the option writer to buy a financial
futures contract upon exercise of the option by the purchaser. If the option
writer agrees to sell a financial futures contract at the option of the
purchaser, 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 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 an authorized 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

Fund to invest in financial futures.
<PAGE>

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.

      Financial futures are generally used as a hedge to protect against
possible changes in interest rates and security prices. 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,
authorized funds 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, authorized funds may enter
into interest rate futures sales contracts.

      The purchase of a futures contract could also enable an authorized fund to
take the approximate economic equivalent of a substantial position in bonds or
equity securities. In this way, the purchase and sale of stock index and
interest rate futures can be used to maintain market exposure and manage cash
flows.

      Under this Proposal, the Growth & Income Fund would be authorized to
invest in financial futures contracts and options on such futures contracts for
"bona fide hedging" purposes (as defined in the regulations of the Commodity
Futures Trading Commission), and for other permissible purposes that are
consistent with the Fund's investment objective. The Fund will not purchase,
sell or write futures contracts or options thereon, other than for "bona fide
hedging" purposes, 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 out-standing non-hedging options on
futures contracts, exceeds 5% of the market value of the Fund's net assets.

Trustees' Recommendation

      The Board of Trustees believes that the proposed modification of
investment policies to clearly permit the Growth & Income Fund to invest in
financial futures is in the best interests of the Shareholders of that Fund.

      THE BOARD OF TRUSTEES UNANIMOUSLY RECOMMEND THAT THE SHAREHOLDERS OF THE
GROWTH & INCOME FUND GIVE INSTRUCTIONS TO VOTE FOR THE APPROVAL OF THE

                     PROPOSALS 3A and 3B -- ACTIVE BOND FUND

              AMENDMENTS TO THE SUB-INVESTMENT MANAGEMENT AGREEMENT
                   AND TO THE INVESTMENT MANAGEMENT AGREEMENT
                            FOR THE ACTIVE BOND FUND

      At its July 14, 2000 meeting, the Board of Trustees unanimously approved,
and voted to recommend that Shareholders approve, amendments to the
Sub-Investment Management Agreement and the Investment Management Agreement that
would increase fees payable by John Hancock to the sub-investment manager and
increase fees payable by the Trust to John Hancock for management of the Active
Bond Fund. Shareholders will need to approve both Proposals in order to
implement either.

Reasons for these Proposals

      The amendments to the Sub-Investment Management Agreement and the
Investment Management Agreement for the Fund are being submitted for shareholder
approval at the Meeting. Both amendments must be approved by Shareholders before
either of them can go into effect.

The Proposed Amendment to the Sub-Investment Management Agreement

      The current sub-investment manager for the Active Bond Fund is John
Hancock Advisers, Inc. ("Advisers"). Advisers has been the Fund's sub-investment
manager since May 1, 1995, pursuant to a Sub-Investment Management Agreement
with the Trust and John Hancock. That agreement was last approved by
Shareholders of the Fund on April 14, 1997. Under the Sub-Investment Management
Agreement, Advisers provides a continuing and suitable investment program for
the Fund consistent with the investment policies, objectives and restrictions of
the Fund. Advisers manages the investment and reinvestment of the assets of the
Fund subject to the overall supervision, direction, control and review of John
Hancock and the Trust.

      In recommending to the Trustees the increase in sub-investment advisory
fees for Advisers, John Hancock noted that Advisers had provided excellent
long-term performance while maintaining a below-average risk profile as compared
to other funds of this type. The Active Bond Fund has outperformed its benchmark
in 4 of the 5 years that Advisers has been the sub-investment manager.

      Under the current Sub-Investment Management Agreement, Advisers is paid a
fee at the annual rate of 0.1875% of the Fund's average daily net assets. Under
this Proposal, John Hancock will pay Advisers 0.25% of the first $100 million of
the Fund's average daily net assets, 0.20% of the next $150 million, 0.16% of
the next $250 million, 0.125% of the next $500 million, and 0.10% of any
additional amounts. There will be no other changes to the agreement.

      As stated in the agreement, John Hancock will pay all sub-advisory fees to
the sub-investment manager. Therefore, any increase in the sub-advisory fees
need not necessarily result in any additional charge to the Trust or to
Shareholders. However, in this case the higher fees payable to Advisers will be
reflected in the proposed increase to the investment advisory fee to be paid by
the Trust to John Hancock.

The Current Investment Management Agreement and Proposed Amendment

      Pursuant to its Investment Management Agreement with the Trust dated April
12, 1988, John Hancock advises the Trust in connection with policy decisions of
the Active Bond Fund; provides administration of day-to-day operations; provides
personnel, office space, equipment and supplies for the Fund; maintains records
required by the Investment Company Act of 1940; supervises activities of the
sub-investment managers referred to above; and supervises the activities of the
other providers of services to the Fund. That agreement was last approved by the
Shareholders on April 23, 1999.
<PAGE>

      For any fiscal year in which the normal operating costs and expenses of
the Active Bond Fund, exclusive of the investment advisory fees, interest,
brokerage, commissions, taxes and extraordinary expenses outside the control of
John Hancock exceed 0.10% of that Fund's average daily net assets, the current
Investment Management Agreement provides that John Hancock will reimburse that
Fund promptly after the end of the fiscal year in an amount equal to such
excess. There was no reimbursement payable to the Active Bond Fund for the
period ended December 31, 1999.

      Under the current Investment Management Agreement, John Hancock is paid a
fee at the annual rate of 0.25% of the Fund's average daily net assets.

      After evaluating the fees to be charged to the Active Bond Fund in
comparison to the cost of services to be rendered by John Hancock, John Hancock
recommended to the Board of Trustees at its July 14, 2000 meeting that the
current Investment Management Agreement be amended to reflect an increase in the
Fund's investment advisory fees to 0.70% for the first $100 million of the
Fund's average daily net assets, 0.65% of the next $150 million, 0.61% of the
next $250 million, 0.58% of the next $500 million, and 0.55% for any additional
amounts. At each of those levels, total expenses (i.e., advisory fees plus other
fund expenses capped as previously noted) would be 0.03% higher (based upon 1999
expenses). If the increase had been in effect during 1999, (i) the Trust would
have paid John Hancock $5,438,730.00 on behalf of the Active Bond Fund, rather
than the $2,214,912.00 paid under the current Investment Management Agreement
(a 145.6% increase), and (ii) the ratio of total expenses to average daily net
assets would have been 0.64% rather than 0.28%. However, the 0.64% ratio
compares favorably with total expense ratio currently incurred by funds that
support other variable insurance products and that have similar investment focus
and asset characteristics. The average total expense ratio for all such funds is
0.66%. The foregoing analysis is based upon a study prepared for the Board by
John Hancock using data collected by Morningstar, Inc., an independent
statistical service that tracks expense data on variable insurance funds. See
the table in Appendix A-1 for a tabular comparison of the actual expense ratios
                                -------
for 1999 with expense ratios that would have been produced by the proposed
modifications had they been in effect during 1999.

Rationale For Proposed Changes In Management Fees

                   After conducting a complete review of the level of investment
management fees for comparable bond funds, John Hancock noted the following:

     .    Since the inception of the Active Bond Fund, there has been a
          substantial increase in the commitment of qualified personnel,
          resources and sophisticated information systems and technology by John
          Hancock to support its increasingly complex investment management
          activities on behalf of the Trust.

     .    The current investment management fee level of the Fund (established
          in 1972) is significantly below the average contractual fee level for
          other mutual funds within the variable insurance products marketplace
          having similar investment focus and asset characteristics.

John Hancock wished to establish a new fee schedule for the Fund that would:

     .    remain competitive with other funds in the current variable insurance
          products marketplace having a similar investment focus and asset
          characteristics;

     .    provide appropriate financial incentives, within the current
          competitive environment, to support John Hancock's increased
          allocation of personnel and resources to the Trust; and

     .    provide a level of financial incentive that would make it easier for
          John Hancock to include the Fund as an investment option in its new
          insurance products.

     As a result of this review and analysis, John Hancock discussed with the
Board the changing nature of compensation in the variable insurance marketplace
and John Hancock's position relative to marketplace trends in pricing. At the
July 14, 2000 Board Meeting, the full Board met to review and consider John
Hancock's proposed recommendation to implement a new investment management fee
schedule for the Fund.
<PAGE>

Basis For The Trustees' Recommendation

     At a meeting held on July 14, 2000, the Board of Trustees, including all
the Trustees who are not "interested persons" of the Fund (the "Independent
Trustees"), unanimously approved a modified management fee schedule for the
Active Bond Fund. The Board is proposing that Shareholders approve an Amended
and Restated Investment Management Agreement between the Trust and John Hancock
("New Management Agreement") in order to modify the current investment
management fee schedule. The proposed new schedule of investment management fee
rates for the Active Bond Fund is as stated above.

     In evaluating and approving the New Management Agreement, the Board,
including the Independent Trustees and in consultation with independent counsel
to the Trust, requested and evaluated information provided by John Hancock
which, in the Board's opinion, constituted all the information reasonably
necessary for the Board to form a judgment as to whether the New Management
Agreement and management fee structure would be in the best interests of the
Active Bond Fund and its Shareholders.

     In making its decision to approve the modified management fee schedule, the
Board considered, among other factors, the following:

     .    The comparability of the investment management fees and other expenses
          that would be paid by the Fund under the New Management Agreement to
          those paid to other funds within the current variable insurance
          marketplace having similar investment focus and asset characteristics.

     .    The significantly increased commitment of personnel and resources
          required of John Hancock, since the inception of the Fund, to support
          the investment management services provided to the Fund, and the
          increased sophistication of the investment evaluation and monitoring
          process used by John Hancock on behalf of the Fund.

     .    The impact of the proposed changes in investment management fee rates
          and changes in other expenses of the Fund on the Fund's total expense
          ratio.

     .    The historical investment record of John Hancock in managing the Fund,
          as well as performance information regarding other funds within the
          current variable insurance marketplace not advised or managed by John
          Hancock but having similar investment focus and asset types.

     .    The Board's favorable evaluation of the nature, quality and breadth of
          investment management services provided by John Hancock to the Fund
          since its inception.

     .    Current and projected profits to John Hancock, both under the current
          investment management fee schedule and the proposed new investment
          management fee schedule, from providing investment management services
          to the Trust and from the John Hancock insurance products which use
          the Trust as a funding medium.

     .    The need to provide sufficient revenues to John Hancock, within the
          competitive marketplace, to promote the Fund as a funding medium for
          variable insurance products it may market in the future.

     Based upon all of the above factors, the Board (including the Independent
Trustees) determined that the new management fee arrangement proposed by John
Hancock was fair, reasonable and in the best interests of the Fund and its
Shareholders.

      The Board of Trustees has determined that the amended Sub-Investment

                               PROPOSALS 4A and 4B
             SMALL CAP VALUE, GLOBAL BALANCED AND GLOBAL BOND FUNDS

          APPROVAL OF A NEW SUB-INVESTMENT MANAGEMENT AGREEMENT AND
               AMENDMENT TO THE INVESTMENT MANAGEMENT AGREEMENT
        FOR THE SMALL CAP VALUE, GLOBAL BALANCED AND GLOBAL BOND FUNDS

     At its July 14, 2000 meeting, the Board of Trustees unanimously approved,
and voted to recommend that Shareholders approve, a new Sub-Investment
Management Agreement with Capital Guardian and a related amendment to the
Investment Management Agreement that would increase fees payable by the Trust to
John Hancock for management of the Small Cap Value Fund, Global Balanced Fund
and Global Bond Fund. Shareholders of any of the Funds will need to approve both
Proposals in order to implement either. Approval of both Proposals by any Fund
will be effective as to that Fund, even if either or both of the other Funds
fail to approve both Proposals.

Reasons for these Proposals

     The Sub-Investment Management Agreement with Capital Guardian, and a
related amendment to the Investment Management Agreement for the Funds, are
being submitted for shareholder approval at the Meeting. Both agreements must be
approved by Shareholders of any Fund before either of them can go into effect.

The Sub-Investment Management Agreement with Capital Guardian

     The current sub-investment managers for the Funds are as follows:

     .  Small Cap Value Fund - - INVESCO Management & Research, Inc.
        ("INVESCO")

     .  Global Balanced Fund - - Brinson Partners, Inc. ("Brinson")

     .  Global Bond - - J.P. Morgan Investment Management, Inc. ("J.P.
        Morgan").

At its meeting on July 14, 2000, the Board, upon John Hancock's recommendation,
decided that the Funds' sub-investment management relationships with INVESCO,
Brinson and J.P. Morgan should be terminated, and that Capital Guardian should
be appointed as successor for the reasons described in greater detail below. The
terminations would only take effect upon shareholder approval of the
Sub-Investment Management Agreement with Capital Guardian that is the subject of
this Proposal.

     The principal reasons for John Hancock's recommendation to replace the
current sub-investment managers were (i) to seek improved investment performance
for the Fund, and (ii) the opportunity to form a strategic relationship with a
premier investment manager. Such a strategic relationship is expected to result
in more effective management and oversight of these Funds by reducing the number
of sub-advisors from three to one. Among the factors that the John Hancock
considered in focusing upon Capital Guardian were the following:

     .  Strong organization with experience and significant resources
        (investment and operations personnel) dedicated to the development and
        management of small cap equity, global balanced and global bond
        portfolios.

     .  Disciplined and well-defined investment process for investing in
        equity and fixed income securities.

     .  Strong long-term performance record in managing small cap equity,
        global balanced and global bond portfolios.

     .  Sub-investment advisory fees that are competitive relative to other
        portfolios with a similar investment focus.

     .  Capital Guardian's reputation and presence in the variable products
        marketplace and its potential for increasing the growth in Fund assets.

John Hancock recommended to the Board of Trustees that Capital Guardian be
retained as the new sub-investment manager of all three Funds.
<PAGE>

      For the Small Cap Value Fund, John Hancock currently pays INVESCO a
sub-investment advisory fee of 0.55% of the first $100 million of the Fund's
average daily net assets; 0.50% of the next $100 million; and 0.40% of any
additional amounts. Under this Proposal, John Hancock will pay Capital Guardian
0.65% of the first $150 million; 0.50% of the next $150 million, 0.40% of the
next $200 million, and 0.35% of any additional amounts.

      For the Global Balanced Fund, John Hancock currently pays Brinson a
sub-investment advisory fee of 0.50% of the first $100 million of the Fund's
average daily net assets; and 0.35% of any additional amounts. Under this
Proposal, John Hancock will pay Capital Guardian 0.65% of the first $150
million; 0.55% of the next $150 million, 0.40% of the next $200 million, and
0.35% of any additional amounts.

      For the Global Bond Fund, John Hancock currently pays J.P. Morgan a
sub-investment advisory fee of 0.50% of the first $25 million of the Fund's
average daily net assets; 0.40% of the next $50 million; 0.30% of the next $75
million, and 0.25% of any additional amounts. Under this Proposal, John Hancock
will pay Capital Guardian 0.40% of the first $150 million; 0.35% of the next
$150 million, 0.30% of the next $200 million, and 0.25% of any additional
amounts.

      A copy of the form of the Sub-Investment Management Agreement is included
as Appendix B-3 to this statement. As stated in the agreement, John Hancock will
pay all sub-advisory fees to the sub-investment manager. Therefore, any increase
in the sub-advisory fees need not necessarily result in any additional charge to
the Trust or to Shareholders. However, in this case the higher fees payable to
Capital Guardian will be reflected in the proposed increase to the investment
advisory fee to be paid by the Trust to John Hancock.

The Current Investment Management Agreement with John Hancock and Proposed
Amendment

      Pursuant to its Investment Management Agreement with the Trust dated March
14, 1996, John Hancock advises the Trust in connection with policy decisions of
the Funds; provides administration of day-to-day operations; provides personnel,
office space, equipment and supplies for the Funds; maintains records required
by the Investment Company Act of 1940; supervises activities of the
sub-investment managers referred to above; and supervises the activities of the
other providers of services to the Funds. That agreement was last approved by
the Shareholders on April 23, 1999.

      For any fiscal year in which the normal operating costs and expenses of
any of the Funds, exclusive of the investment advisory fees, interest,
brokerage, commissions, taxes and extraordinary expenses outside the control of
John Hancock, exceed 0.10% of that Fund's average daily net assets, the current
Investment Management Agreement provides that John Hancock will reimburse that
Fund promptly after the end of the fiscal year in an amount equal to such
excess. The reimbursement paid to the Funds for the period ended December 31,
1999 was as follows: Small Cap Value Fund - $6,224.00, Global Balanced Fund -
$91,146.00, and Global Bond Fund - $1,445.00

      Under the current Investment Management Agreement, John Hancock is paid
advisory fees at the following annual rates:

      .  Small Cap Value Fund - 0.80% of the first $100 million of the Fund's
         average daily net assets; 0.75% of the next $100 million, and 0.65%
         of any additional amounts.

      .  Global Balanced Fund - 0.85% of the first $100 million of the Fund's
         average daily net assets; and 0.70% of any additional amounts.

      .  Global Bond Fund - 0.75% of the first $25 million of the Fund's average
         daily net assets; 0.65% of the next $50 million, 0.55% of the next $75
         million and 0.50% of any additional amounts.

      After evaluating the fees to be charged to the Funds in comparison to the
cost of services to be rendered by John Hancock and the fees to be paid to the
new sub-investment manager, John Hancock recommended to the Board of Trustees at
its July 14, 2000 meeting that the current Investment Management Agreement be
amended to reflect an increase in each Fund's investment advisory fees to the
following levels:
<PAGE>

     .    Small Cap Value Fund - 0.90% of the first $150 million of the Fund's
          average daily net assets, 0.75% of the next $150 million, 0.65% of the
          next $200 million, and 0.60% of any additional amounts.

     .    Global Balanced Fund - 1.05% of the first $150 million of the Fund's
          average daily net assets, 0.95% of the next $150 million, 0.80% of the
          next $200 million, and 0.75% of any additional amounts.

     .    Global Bond Fund - 0.85% of the first $150 million of the Fund's
          average daily net assets, 0.80% of the next $150 million, 0.75% of the
          next $200 million, and 0.70% of any additional amounts.

At each breakpoint level of each Fund, total expenses (i.e., advisory fees plus
                                       -----
other fund expenses capped as previously noted) would be 0.10% higher.

      If the increases had been in effect during 1999 for the Small Cap Value
Fund, (i) the Trust would have paid John Hancock $576,718.00 on behalf of the
Small Cap Value Fund, rather than the $512,633.00 paid under the current
Investment Management Agreement (a 12.5% increase), and (ii) the ratio of total
expenses to average daily net assets would have been 1.00% rather than 0.90%.
However, the 1.00% ratio compares favorably with total expense ratios currently
incurred by funds that support other variable insurance products, that have
similar investment focus and asset characteristics, and that are of a size
comparable to the Small Cap Value Fund (i.e., less than $100 million in assets).
The average total expense ratio for all such funds is 0.93%.

      If the increases had been in effect during 1999 for the Global Balanced
Fund, (i) the Trust would have paid John Hancock $312,578.00 on behalf of the
Global Balanced Fund, rather than the $253,044.00 paid under the current
Investment Management Agreement (a 23.5% increase), and (ii) the ratio of total
expenses to average daily net assets would have been 1.15% rather than 0.95%.
However, the 1.15% ratio compares favorably with total expense ratios currently
incurred by funds that support other variable insurance products, that have
similar investment focus and asset characteristics, and that are of a size
comparable to the Global Balanced Fund (i.e., less than $100 million in assets).
The average total expense ratio for all such funds is 1.18%.

If the increases had been in effect during 1999 for the Global Bond Fund, (i)
the Trust would have paid John Hancock $605,565.00 on behalf of the Global
Balanced Fund, rather than the $488,070.00 paid under the current Investment
Management Agreement (a 24.1% increase), and (ii) the ratio of total expenses to
average daily net assets would have been 0.95% rather than 0.79%. However, the
0.95% ratio compares favorably with total expense ratios currently incurred by
funds that support other variable insurance products and that have similar
investment focus and asset characteristics. The average total expense ratio for
all such funds is 1.06%.

      The foregoing analysis for each of the Funds is based upon a study
prepared for the Board by John Hancock using data collected by Morningstar,
Inc., an independent statistical service that tracks expense data on variable
insurance funds. See the table in Appendix A-1 for a tabular comparison of the
                                                     -------
actual expense ratios for 1999 with expense ratios that would have been produced
by the proposed modifications had they been in effect during 1999.

      In all other respects, the current Investment Management Agreement, as
described in Appendix C to this statement, will remain unchanged.

Rationale For Proposed Changes In Management Fees

      After conducting a complete review of the level of investment management
fees for comparable funds, John Hancock noted the following:

     .    Since the inception of the Funds, there has been an increase in the
          commitment of qualified personnel, resources and sophisticated
          information systems and technology by John Hancock to support its
          increasingly complex investment management activities on behalf of the
          Trust.
<PAGE>

     .    The current investment management fee levels of the Funds are below
          the average contractual fee levels for other mutual funds within the
          variable insurance products marketplace having similar investment
          focus and asset characteristics (significantly below with respect to
                                           -------------
          the Global Balanced and Global Bond Funds).

John Hancock wished to establish a new fee schedule for each of the Funds that
would:

     .    remain competitive with other funds in the current variable insurance
          products marketplace having a similar investment focus and asset
          characteristics; and

     .    provide appropriate financial incentives, within the current
          competitive environment, to support John Hancock's increased
          allocation of personnel and resources to the Funds.

     As a result of this review and analysis, John Hancock discussed with the
Board the changing nature of compensation in the variable insurance marketplace
and John Hancock's position relative to marketplace trends in pricing. At the
July 14, 2000 Board Meeting, the full Board met to review and consider John
Hancock's proposed recommendation to implement new investment management fee
schedules for the Funds.

Basis For The Trustee's Recommendation

     At a meeting held on July 14, 2000, the Board of Trustees, including all
the Trustees who are not "interested persons" of the Funds (the "Independent
Trustees"), unanimously approved a modified management fee schedule for each of
the Funds. The Board is proposing that Shareholders approve an Amended and
Restated Investment Management Agreement between the Trust and John Hancock
("New Management Agreement") in order to modify the current investment
management fee schedules. The proposed new schedule of investment management fee
rates for the Small Cap Value, Global Balanced and Global Bond Funds is as
stated above.

      In evaluating and approving the New Management Agreement, the Board,
including the Independent Trustees and in consultation with independent counsel
to the Trust, requested and evaluated information provided by John Hancock
which, in the Board's opinion, constituted all the information reasonably
necessary for the Board to form a judgment as to whether the New Management
Agreement and management fee structure would be in the best interests of the
Small Cap Value, Global Balanced and Global Bond Fund and their Shareholders.

      In making its decision to approve the modified management fee schedule,
the Board considered, among other factors, the following:

     .    The comparability of the investment management fees and other expenses
          that would be paid by the Fund under the New Management Agreement to
          those paid to other funds within the current variable insurance
          marketplace having similar investment focus and asset characteristics.

     .    The significantly increased commitment of personnel and resources
          required of John Hancock, since the inception of the Funds, to support
          the investment management services provided to the Funds, and the
          increased sophistication of the investment evaluation and monitoring
          process used by John Hancock on behalf of the Funds.

     .    The impact of the proposed changes in investment management fee rates
          and changes in other expenses of each Fund on each Fund's total
          expense ratio and the continued willingness of John Hancock to agree
          to limit total operating expenses for each Fund.

     .    The historical investment record of John Hancock in managing each of
          the Funds, as well as performance information regarding other funds
          within the current variable insurance marketplace not advised or
          managed by John Hancock but having similar investment focus and asset
          types.

     .    The Board's favorable evaluation of the nature, quality and breadth of
          investment management services provided by John Hancock to the Funds
          since their inception.

     .    Current and projected profits to John Hancock, both under the current
          investment management fee schedule and the proposed new investment
          management fee schedule, from providing investment
<PAGE>

          management services to the Trust and from the John Hancock insurance
          products which use the Trust as a funding medium.

     .    The need to provide sufficient revenues to John Hancock, within the
          competitive marketplace, to promote the Funds as a funding medium for
          variable insurance products it may market in the future and increase
          the opportunities for growth in the Funds' assets.

     .

      Based upon all of the above factors, the Board (including the Independent
Trustees) determined that the new management fee arrangement proposed by John
Hancock was fair, reasonable and in the best interests of the Funds and the
Funds' Shareholders.

                          RECORD DATE AND VOTING SHARES

      As of the close of business on August 31, 2000 ("the record date"), there
were the following shares outstanding:

      Each Trust share is entitled to one vote, and fractional votes will be
counted.

      The number of Trust shares attributable to each owner of a variable life
insurance policy ("policy") is determined by dividing, as of the record date of
the Meeting, a policy's cash (or account) value (less any outstanding
indebtedness) in the designated subaccount of the applicable Account by the net
asset value of one share in the corresponding Fund in which the assets of the
subaccount are invested. The number of Trust shares attributable to each owner
of a variable annuity contract ("contract") is determined by dividing, as of the
record date of the Meeting, the value of the Accumulation Shares under a
contract (or for each contract under which annuity payments have commenced, the
equivalent determined by dividing the contract reserves by the value of one
Accumulation Share) in the designated subaccount of the applicable Account by
the net asset value of one share in the corresponding Fund in which the assets
of the subaccount are invested.

      As of the close of business on August 31, 2000, John Hancock, JHVLICO and
IPL had in the aggregate the following numbers of shares representing their
contributions and other amounts in the Accounts that are in excess of the
amounts attributable to policies and contracts:

2. PROVISION OF INVESTMENT MANAGEMENT SERVICES.

     Advisers will provide for the Subject Fund's assets as may be designated to
it by JHLICO from time to time (the "Subject Assets") a continuing and suitable
investment program consistent with the investment policies, objectives and
restrictions of said Fund, as established by the Trust and JHLICO. From time to
time, JHLICO or the Trust may provide Advisers in writing (including, without
limit, electronic communication) with additional or amended investment policies,
procedures, guidelines and restrictions with the opportunity for prior review by
Advisers. Advisers, as a sub-manager, will use due care to manage the investment
and reinvestment of the Subject Assets, and perform the functions set forth
below, subject to the overall supervision, direction, control and review of
JHLICO and the Board of Trustees of the Trust, consistent with the applicable
investment policies, guidelines and restrictions, the provisions of the Trust's
Declaration of Trust, Bylaws, prospectus, statement of additional information
(each as in effect from time to time), provisions of the 1940 Act and all other
applicable laws and regulations deemed to be Sub-Advisers' duty under the
Subject Funds' compliance manual and procedures (including any applicable
investment restrictions imposed by state insurance laws and regulations or any
directions or instructions delivered to Advisers in writing by JHLICO or the
Trust from time to time) as is mutually agreed to from time to time, such
agreement not to be unreasonably withheld. In the event that, in addition to
Advisers, other investment advisers or sub-managers are appointed by the Trust
or JHLICO to render investment advisory services to the Subject Fund, JHLICO and
the Trust each acknowledges and agrees that Advisers will not be held
responsible for such other investment advisers' or sub-managers' compliance with
policies and limitations applicable to the Subject Fund. By its signature below,
Advisers acknowledges receipt of a copy of the Trust's Declaration of Trust,
Bylaws, prospectus, and statement of additional information, each as in effect
on the date of this Agreement.

     Advisers will, at its own expense:

     (a)  upon request, furnish the Trust with research, economic and
          statistical data in connection with said Fund's investments and
          investment policies including , without limit, investment policy
          decisions to be made by the Trust's Board of Trustees or any committee
          thereof regarding the Subject Fund;

     (b)  submit such reports and information as JHLICO or the Trust's Board of
          Trustees may reasonably request, to reasonably assist the custodian in
          its determination of the market value of securities held in the
          Subject Assets;

     (c)  place orders for purchases and sales of portfolio investments for the
          Subject Assets;

     (d)  give instructions to the Subject Fund's custodian concerning the
          delivery of securities and transfer of cash for the Subject Assets;

     (e)  maintain and preserve the records relating to its activities hereunder
          required by the 1940 Act to be maintained and preserved by the Trust;

     (f)  at the close of business each day, provide JHLICO and the custodian
          with copies of trade tickets for each transaction effected for the
          Subject Assets, and promptly forward to the custodian copies of all
          brokerage or dealer confirmations;

     (g)  as soon as practicable following the end of each calendar month,
          provide JHLICO with written statements showing all transactions
          effected for the Subject Assets during the month, a summary listing
          all investments held in the Subject Assets as of the last day of the
          month, and such other information as JHLICO may reasonably request in
          connection with the accounting services that JHLICO provides for the
          Subject Fund;

     (h)  subject to its receipt of all necessary voting materials, vote all
          proxies with respect to investments of the Subject Assets in
          accordance with Advisers' proxy voting policy as most recently
          supplied to JHLICO, or in such other manner as JHLICO and Advisers may
          reasonably agree upon from time to time; and

     (i)  provide timely information to JHLICO and the Trust concerning Advisers
          and its activities hereunder in connection with the Subject Assets to
          assure accurate disclosure of such matters (or information necessary
          to make the statements not misleading) in any Prospectus, Statement of
          Additional Information or registration statement of the Trust or
          JHLICO, or in any sales literature or materials for the sale or
          distribution of the Trust's shares, it being understood that JHLICO
          and the Trust shall otherwise be solely responsible for the accuracy
          of such documents.

     On its own initiative, Advisers will apprise JHLICO and the Trust of
important economic developments materially affecting the marketplace or the
Subject Assets, and will furnish JHLICO and the Trust's Board of Trustees from
time to time such information as is appropriate for this purpose. Advisers will
also make its personnel available in Boston or other reasonable locations as
often as quarterly to discuss the Subject Assets and Advisers' management
thereof, to educate JHLICO sales personnel with respect thereto (in such manner
and format as the parties reasonably agree upon from time to time), and for such
other purposes as the Trust or JHLICO may reasonably request.

     The Trust and JHLICO will provide timely information to Advisers regarding
such matters as purchases and redemptions of shares in the Subject Fund and the
cash requirements of, and cash available for investment in, the Subject Fund.
JHLICO will timely provide Advisers with copies of monthly accounting statements
for the Subject Fund, and such other information (including, without limitation,
reports concerning the classification of portfolio securities of the Subject
Fund for purposes of Subchapter M of the Internal Revenue Code and Treasury
Regulations Section 1.817) as may be reasonably necessary or appropriate in
order for Advisers to perform its responsibilities hereunder.

     Advisers shall have no duty or obligation to the Trust or to JHLICO, and
shall not be expected or responsible to perform any service or function with
respect thereto, except as is expressly stated in this Agreement.

3.   ALLOCATION OF EXPENSES.

     Each party to this Agreement shall bear the costs and expenses of
performing its obligations hereunder. In this regard, the Trust specifically
agrees to assume the expense of:
<PAGE>

                                      -4-

     (a)  brokerage commissions for transactions in the portfolio investments of
          the Trust and similar fees and charges for the acquisition,
          disposition, lending or borrowing of such portfolio investments;

     (b)  custodian fees and expenses;

     (c)  all taxes, including issuance and transfer taxes, and reserves for
          taxes payable by the Trust to federal, state or other governmental
          agencies; and

     (d)  interest payable on the Trust's borrowings.

Nothing in this Agreement shall alter the allocation of expenses and costs
agreed upon between the Trust and JHLICO in the Investment Management Agreement
or any other agreement to which they are parties.

4.   SUB-ADVISORY FEES.

     For all of the services rendered with respect to the Subject Assets as
herein provided, JHLICO shall pay to Advisers a fee (for the payment of which
the Trust shall have no obligation or liability), based on the Current Net
Assets (as defined below) of the Subject Assets, as set forth in Schedule I
attached hereto and made a part hereof. Such fee shall be accrued daily and
payable monthly, as soon as practicable after the last day of each calendar
month. In the case of termination of this Agreement with respect to the Subject
Assets during any calendar month, the fee with respect to the Subject Assets
accrued to but excluding the date of termination shall be paid promptly
following such termination. For purposes of computing the amount of advisory fee
accrued for any day, "Current Net Assets" shall mean the net assets as of the
most recent preceding day for which that Subject Fund's net assets were
determined by the Subject Fund's Custodian or by the Subject Fund's
administrator, as the case may be.

5.   PORTFOLIO TRANSACTIONS.

     In connection with the investment and reinvestment of the assets of the
Subject Assets, Advisers is authorized to select the brokers or dealers that
will execute purchase and sale transactions for the Subject Assets and to use
its best efforts to obtain the best available price and most favorable execution
with respect to all such purchases and sales of portfolio securities for said
Subject Assets. Advisers shall maintain records adequate to demonstrate
compliance with this requirement. Subject to this primary requirement, and
maintaining as its first consideration the benefits to the Subject Fund and its
shareholders, Advisers shall have the right subject to the control of the Board
of Trustees, and to the extent authorized by the Securities Exchange Act of
1934, to follow a policy of selecting brokers who furnish brokerage and research
services to the Subject Fund or to the Advisers, and who charge a higher
commission rate to the Subject Fund than may result when allocating brokerage
solely on the basis of seeking the most favorable price and execution. Advisers
shall determine in good faith that such higher cost was reasonable in relation
to the value of the brokerage and research services provided.

     Advisers will not receive any tender offer solicitation fees or similar
payments in connection with the tender of investments of any Fund.

6.   OWNERSHIP OF INFORMATION, RECORDS, AND CONFIDENTIALITY.

     The Trust shall own and control all records maintained hereunder by
Advisers on the Trust's behalf and, in the event of termination of this
Agreement with respect to the Subject Assets for any reason, upon request of the
Trust or its designee, all records relating to the Subject Fund shall be
<PAGE>

                                      -5-

promptly returned to the Trust, free from any claim or retention of rights by
Advisers, provided that (subject to the last paragraph of this Section 6)
Advisers may retain copies of such records. Advisers also agrees, upon request
of the Trust, promptly to surrender such books and records or, at its expense,
copies thereof, to the Trust or make such books and records available for audit
or inspection by representatives of regulatory authorities or other persons
reasonably designated by the Trust. Advisers further agrees that with respect to
its activities hereunder, it shall maintain, prepare and preserve such books and
records as are required in accordance with the 1940 Act and rules thereunder,
including but not limited to Rules 31a-1 and 31a-2, and supply all information
requested by any insurance regulatory authorities to determine whether all
insurance laws and regulations are being complied with. Advisers shall supply
the Board of Trustees and officers of the Trust and JHLICO with all statistical
information regarding investments made on behalf of the Subject Assets which is
reasonably required by them and reasonably available to Advisers.

     Advisers shall not disclose or use any records or information obtained
pursuant hereto in any manner whatsoever except as expressly authorized herein,
and will keep confidential any information obtained pursuant hereto, and
disclose such information only if the Trust has authorized such disclosure, or
(after reasonable notice to the Trust) if such disclosure is expressly requested
by applicable federal or state regulatory authorities.

7.   LIABILITY; STANDARD OF CARE.

     No provision of this Agreement shall be deemed to protect Advisers against
any liability to the Trust or its shareholders to which it might otherwise be
subject by reason of any willful misfeasance, bad faith or negligence in the
performance of its duties or the reckless disregard of its obligations and
duties under this Agreement. No provision of this Agreement shall be deemed to
protect JHLICO against any liability to the Trust or its shareholders to which
it might otherwise be subject by reason of any willful misfeasance, bad faith or
negligence in the performance of its duties or the reckless disregard of its
obligations and duties under the Investment Management Agreement. Nor shall any
provision hereof be deemed to protect any trustee or officer of the Trust
against any such liability to which he might otherwise be subject by reason of
any willful misfeasance, bad faith or negligence in the performance his duties
or the reckless disregard of his obligations and duties. Advisers shall employ
only qualified personnel to manage the Subject Assets; shall comply with all
applicable laws and regulations in the discharge of its duties under this

for such purposes) as a regulated investment company in accordance with
subchapter M of the Internal Revenue Code of 1986, as amended (the "Code"), and
Treasury Regulations Section 1.817-5(b); shall act at all times in the best
interests of the Trust; and shall discharge its duties with the care, skill,
prudence and diligence under the circumstances then prevailing that a prudent
person acting in a like capacity and familiar with such matters would use in the
conduct of a similar enterprise. However, Advisers shall not be obligated to
perform any service not described in this Agreement, and shall not be deemed by

          Agreement has not been approved by the holders of a majority of the
          outstanding shares of any other Fund affected hereby, and (B) that
          this Agreement has not been approved by the vote of a majority of the

          Fund management services and advice to other investment companies,
          whether or not registered, and other investment advisory clients.

          or service mark (including but not limited to the American Funds Group
          of mutual funds) (collectivley referred to as the "Protected
          Information"), are the valuable property of the Advisers and its
          affiliates. The Trust and JHLICO shall have the right to use the
          Protected Information provided that, prior to distribution of any
          materials which refer to Advisers or the Protected Information, JHLICO
          shall consult with Advisers and shall furnish to Advisers a copy of
          such materials. Advisers agrees to cooperate with JHLICO and to review
          such materials promptly. JHLICO shall not distribute such materials if

          of its receipt of such copy (or such other time as may be mutually

10.  AVOIDANCE OF INCONSISTENT POSITION.

Subject Fund, Advisers and its directors, officers and employees will not act as
principal or agent or receive any commission. Nothing in this Agreement,

Advisers or its affiliates, if orders are allocated in a manner deemed equitable
by Advisers among the accounts and at a price approximately averaged.

                                      AMONG

                      JOHN HANCOCK VARIABLE SERIES TRUST I

                    INDEPENDENCE INVESTMENT ASSOCIATES, INC.

                                       AND

                       JOHN HANCOCK LIFE INSURANCE COMPANY
<PAGE>

                       SUB-INVESTMENT MANAGEMENT AGREEMENT

      AGREEMENT made as of the day of  , 2000 by and among John Hancock Variable
Series Trust I, a Massachusetts business trust (the "Trust"), Independence
Investment Associates, Inc., a Delaware corporation ("IIA"), and John Hancock
Life Insurance Company, a Massachusetts corporation ("JHLICO").

      WHEREAS, the Trust is organized and is engaged in business as an open-end
management investment company and is so registered under the Investment Company
Act of 1940 (the "1940 Act"); and

      WHEREAS, JHLICO and IIA are engaged in the business of rendering
investment advice under the Investment Advisers Act of 1940; and

      WHEREAS, the Trust is authorized to issue shares of capital stock in
separate classes with each such class representing interests in a separate
portfolio of securities and other assets; and

      WHEREAS, the Trust offers shares in several classes, one of which is
designated as the Managed Fund, (together with all other classes established by
the Trust, the "Funds"), each of which pursues its investment objectives through
separate investment policies; and

      WHEREAS, the Trust has retained JHLICO to render investment management
services to the Trust pursuant to an Investment Management Agreement dated as of
April 12, 1988 (the "Investment Management Agreement"), pursuant to which it may
contract with one or more investment advisers as provided for herein;

      NOW, THEREFORE, WITNESSETH: That it is hereby agreed between the parties
hereto as follows:

1.    APPOINTMENT OF SUB-MANAGER

      (a) Subject Fund. IIA is hereby appointed and IIA hereby accepts the
          ------------
appointment to act as an investment adviser and manager to the Managed Fund (the
"Subject Fund"), effective      , 2000, for the period and on the terms herein
                           -----
set forth, for the compensation herein provided.
<PAGE>

                                     -13-

      (b) Additional Subject Funds. In the event that the Trust and JHLICO
          ------------------------
desire to retain IIA to render investment advisory services hereunder for any
other Fund, they shall so notify IIA in writing. If it is willing to render such
services, IIA shall notify the Trust in writing, whereupon such Fund shall
become a Subject Fund hereunder.

      (c) Independent Contractor. IIA shall for all purposes herein be deemed to
          ----------------------
be an independent contractor and shall, unless otherwise expressly provided or
authorized, have no authority to act for or be deemed an agent of the Trust.

2.  PROVISION OF INVESTMENT MANAGEMENT SERVICES.

      IIA will provide for such portion of the Subject Fund's assets as may be
designated to it by JHLICO from time to time (the "Subject Assets") a continuing
and suitable investment program consistent with the investment policies,
objectives and restrictions of said Fund, as furnished to IIA by JHLICO in
writing from time to time. IIA will manage the investment and reinvestment of
the the Subject Assets, and perform the functions set forth below, subject to
the overall supervision, direction, control and review of the Board of Trustees
of the Trust, JHLICO and, as in effect from time to time, the provisions of the
Trust's Declaration of Trust, Bylaws, prospectus, statement of additional
information (all as furnished to IIA by JHLICO in writing from time to time),
the 1940 Act and all other applicable laws and regulations (including any
applicable investment restrictions imposed by state insurance laws and
regulations or any directions or instructions, all as delivered to IIA in
writing by JHLICO or the Trust from time to time).

      IIA will have investment discretion with respect to the Subject Assets and
will, at its own expense:

          (a) upon request, advise the Trust in connection with investment
decisions to be made by its Board of Trustees or any committee thereof regarding
the Subject Assets and furnish the Trust with research, economic and statistical
data in connection with investments and investment policies for the Subject
Assets;

          (b) submit such reports relating to the valuation of the Subject
Assets as the Trust's Board of Trustees may reasonably request;
<PAGE>

                                     -14-

          (c) place orders for purchases and sales of portfolio investments for
the Subject Assets;

          (d) maintain and preserve the records relating to its activities
hereunder, including those records required by the 1940 Act to be maintained by
it and preserved by the Trust, to the extent not maintained by the Trust's
custodian, transfer agent or JHLICO; and

          (e) subject to its receipt of all necessary voting materials, in its
discretion, as it deems advisable in the best interests of the Subject Fund,
vote, or cause to be voted, any or all proxies with respect to the Subject
Assets in accordance with IIA's proxy voting policy as most recently provided to
JHLICO.

      The Trust and JHLICO will provide timely information to IIA regarding such
matters as purchases and redemptions of shares with respect to the Subject
Assets and the cash requirements of, and cash available for investment in, the
Subject Assets, and all information (including, without limitation, reports
concerning the classification of Fund securities for purposes of Subchapter M of
the Internal Revenue Code and Treasury Regulations Section 1.817) as may be
reasonably necessary or appropriate in order for IIA to perform its
responsibilities hereunder. On its own initiative, IIA will apprise JHLICO and
the Trust of important developments materially affecting the Subject Assets and
will furnish JHLICO and the Trust's Board of Trustees from time to time such
information as is appropriate for this purpose.

3.    ALLOCATION OF EXPENSES.

      Each party to this Agreement shall bear the costs and expenses of
performing its obligations hereunder. In this regard, the Trust specifically
agrees, without limitation, to assume the expense of:

      (i) brokerage commissions for transactions in the portfolio investments of
the Subject Assets and similar fees, charges and expenses incurred in connection
with the acquisition, disposition, lending or borrowing of such portfolio
investments;

      (ii) all taxes, including issuance and transfer taxes, and reserves for
taxes payable by the Trust to federal, state or other governmental agencies; and

      (iii) interest payable on the Trust's borrowings.
<PAGE>

                                     -15-

Nothing in this Agreement shall alter the allocation of expenses and costs
agreed upon between the Trust and JHLICO in the Investment Management Agreement
or any other agreement to which they are parties.

4.    SUB-ADVISORY FEES.

      For all of the services rendered as herein provided, JHLICO shall pay to
IIA a fee (for payment of which the Trust shall have no obligation or liability)
based on the Current Net Assets of the Subject Assets, as set forth in Schedule
I attached hereto and made a part hereof. The fee shall be accrued daily and
payable monthly, as soon as practicable after the last day of each calendar
month. In the case of termination of this Agreement with respect to the Subject
Assets during any calendar month, the fee with respect to such Subject Assets
accrued to termination shall be paid promptly following such termination.

      "Current Net Assets" of the Subject Assets for purposes of computing the
amount of advisory fee accrued for any day shall mean the net assets of the
Subject Assets as of the most recent preceding day for which the Subject Assets'
net assets were computed.

5.    FUND TRANSACTIONS.

      In connection with the investment and reinvestment of the assets of the
Subject Fund, IIA is authorized to select the brokers or dealers that will
execute purchase and sale transactions for the Subject Assets and to use its
best efforts to obtain best execution with respect to all such purchases and
sales of Fund securities for said Subject Assets. IIA shall maintain records
reasonably adequate to demonstrate compliance with this requirement. Subject to
this primary requirement, and maintaining as its first consideration the
benefits to the Subject Fund and its shareholders, IIA shall have the right
subject to the control of the Board of Trustees, and to the extent authorized by
the Securities Exchange Act of 1934, to follow a policy of selecting brokers who
furnish brokerage and research services to the Subject Fund or to IIA, and who
charge a higher commission rate to the Subject Fund than may result when
allocating brokerage solely on the basis of seeking the most favorable price and
execution. IIA shall determine in
<PAGE>

                                     -16-

good faith that such higher cost was reasonable in relation to the value of the
brokerage and research services provided.

      The fees payable to IIA by JHLICO hereunder shall be reduced by any tender
offer solicitation fees or similar payments received by IIA, in connection with
the tender of investments of any Subject Assets (less direct expenses incurred
by IIA in connection with obtaining such fees or payments), to the extent not
otherwise paid or credited to the Subject Fund.

6.    INFORMATION, RECORDS, AND CONFIDENTIALITY.

      The Trust shall own and control all records maintained hereunder by IIA on
the Trust's behalf and, in the event of termination of this Agreement with
respect to the Subject Fund for any reason, all records (or true and complete
copies thereof) relating to that Fund shall be promptly returned to the Trust,
free from any claim or retention of rights by IIA. IIA also agrees, upon request
of the Trust, promptly to surrender such books and records or, at its expense,
copies thereof, to the Trust or make such books and records available for
inspection by representatives of regulatory authorities or other persons
reasonably designated by the Trust. IIA further agrees to maintain, prepare and
preserve such books and records in accordance with the 1940 Act and rules
thereunder, including but not limited to, Rules 31a-1 and 31a-2 and to supply
all information in its possession or reasonably available to it, requested by
any insurance regulatory authorities to determine whether all insurance laws and
regulations are being complied with.

      IIA shall not disclose or use any records or information obtained pursuant
hereto in any manner whatsoever except as expressly authorized herein, and will
keep confidential any information obtained pursuant hereto, and disclose such
information only (i) to John Hancock Life Insurance Company, or to any other
person or entity that directly or indirectly owns all or substantially all of
the IIA's capital stock; (ii) if the Trust or JHLICO has authorized such
disclosure, or (iii) if such disclosure is expressly required by applicable
federal or state regulatory authorities or court proceedings.

      IIA shall supply the Board of Trustees and officers of the Trust and
JHLICO with all statistical information regarding investments which is
reasonably required by them and reasonably available to it.

                                     -17-

7.    LIABILITY; STANDARD OF CARE.

      No provision of this Agreement shall be deemed to protect IIA or JHLICO
against any liability to the Trust or its shareholders to which it might
otherwise be subject by reason of any willful misfeasance, bad faith or
negligence in the performance of its duties or the reckless disregard of its
obligations and duties under this Agreement or the Investment Management
Agreement, as applicable. Nor shall any provision hereof be deemed to protect
any trustee or officer of the Trust against any such liability to which he might
otherwise be subject by reason of any willful misfeasance, bad faith or
negligence in the performance of his duties or the reckless disregard of his
obligations and duties. IIA shall employ only qualified personnel to manage the
Subject Assets; shall comply with all applicable laws and regulations in the
discharge of its duties under this Agreement (provided that copies of any
applicable investment restrictions imposed by state insurance laws and
regulations shall be furnished to IIA by JHLICO); shall (as provided in Section
2 above) comply with the investment policies, guidelines and restrictions of the
Subject Fund and with the provisions of the Trust's Declaration of Trust,
Bylaws, prospectus and statement of additional information, all as furnished to
IIA by JHLICO in writing from time to time; shall manage the Subject Assets
(subject to the receipt of, and based upon the information contained in,
periodic reports from JHLICO or the custodian concerning the classification of
Fund securities for such purposes) as a regulated investment company in
accordance with subchapter M of the Internal Revenue Code of 1986, as amended
(the "Code"), and Treasury Regulations Section 1.817-5(b); shall act in its
management of the Subject Assets in the best interests of the Trust, subject
however to its duties to other clients as described in Section 9 below; and
shall discharge its duties with the care, skill, prudence and diligence under
the circumstances then prevailing that a prudent person acting in a like
capacity and familiar with such matters would use in the conduct of a similar
enterprise. However, IIA shall not be obligated to perform any service not
described in this Agreement, and shall not be deemed by virtue of this Agreement
to have made any representation or warranty that any level of investment
performance or level of investment results will be achieved.

8.    DURATION AND TERMINATION OF THIS AGREEMENT.

      (a) Duration. This Agreement shall become effective with respect to the
          --------
Managed Fund on the date set forth in Section 1(a) hereof and, with respect to
any additional Subject Fund, on the date of receipt by the Trust of notice from
IIA in accordance with Paragraph 1(b) hereof that it is willing to serve with
respect to such Fund. Unless terminated as herein provided, this Agreement shall
remain in full force and effect for two years from the date hereof with respect
to the initial Subject Fund and, with respect to each additional Subject Fund,
until two years following the date on which such Fund becomes a Subject Fund
hereunder, and shall continue in full force and effect thereafter with respect
to each Subject Fund so long as such continuance with respect to any such Fund
is approved at least annually (a) by either the Board of Trustees of the Trust
or by vote of a majority of the outstanding voting shares of such Fund, and (b)
in either event by the vote of a majority of the trustees of the Trust who are
not parties to this Agreement or "interested persons" of any such party, cast in
person at a meeting called for the purpose of voting on such approval.

      Any approval of this Agreement by the holders of a majority of the
outstanding shares of any Subject Fund shall be effective to continue this
Agreement with respect to any such Fund notwithstanding (A) that this Agreement
has not been approved by the holders of a majority of the outstanding shares of
any other Fund affected hereby, and (B) that this Agreement has not been
approved by the vote of a majority of the outstanding shares of the Trust,
unless such approval shall be required by any other applicable law or otherwise.
The terms "assignment," "vote of a majority of the outstanding shares" and
"interested person," when used in this Agreement, shall have the respective
meanings specified in the 1940 Act and rules thereunder.

      (b) Termination. This Agreement may be terminated with respect to any
          -----------
Subject Fund at any time, without payment of any penalty, by the Trust pursuant
to a vote of the trustees of the Trust or a vote of a majority of the
outstanding shares of such Fund, which termination shall be effective
immediately upon delivery of notice thereof to IIA and JHLICO. This Agreement
may be terminated by IIA on at least sixty days' prior written notice to the
Trust and JHLICO, or by JHLICO on at least sixty days' prior written
<PAGE>

                                     -19-

notice to the Trust and IIA. Transactions already entered into by IIA but not
yet settled at the time of any such termination shall settle for the account of
the Trust.

      (c) Automatic Termination. This Agreement shall automatically and
          ---------------------
immediately terminate in the event of its assignment or if the Investment
Management Agreement is terminated.

9.  SERVICES NOT EXCLUSIVE.

      The services of IIA to the Trust are not to be deemed exclusive and it
shall be free to render similar services to others so long as its services
hereunder are not impaired thereby. It is specifically understood that
directors, officers and employees of IIA and of its subsidiaries and affiliates
may continue to engage in providing portfolio management services and advice to
other investment companies, whether or not registered, and other investment
advisory clients.

      Nothing in this Agreement shall limit or restrict IIA or any of its
officers, affiliates or employees from buying, selling or trading in any
securities for its or their own accounts; provided, however, that no such person
shall purchase securities from or sell securities to the Subject Fund except as
permitted under applicable laws and regulations, including without limitation
the 1940 Act and the Investment Advisers Act of 1940, and the rules and
regulations thereunder. The Trust acknowledges that IIA and its officers,
affiliates and employees, and its and their other clients, may at any time have,
acquire, increase, decrease or dispose of positions in investments which are at
the same time being acquired or disposed of under this Agreement. IIA shall have
no obligation to acquire for the Subject Fund a position in any investment which
IIA, its officers, affiliates or employees may acquire for their own accounts or
for the account of another client, if in the sole discretion of IIA it is not
feasible or desirable to do so.

10.  AVOIDANCE OF INCONSISTENT POSITION.

      In connection with the purchase and sale of portfolio securities of the
Subject Assets, IIA and its directors, officers and employees will not act as
principal or agent or receive any commission, except as may be permitted under
applicable laws and regulations and the policies and procedures of the Trust in
<PAGE>

                                     -20-

effect from time to time. Nothing in this Agreement, however, shall preclude the
combination of orders for the sale or purchase of portfolio securities of the
Subject Assets with those for other accounts managed by IIA or its affiliates,
if orders are allocated in a manner deemed equitable by IIA among the accounts
and at a price approximately averaged.

11.  AMENDMENT.

     No provision of this Agreement may be changed, waived, discharged or
terminated orally, but only by an instrument in writing signed by a duly
authorized officer of the party or parties intending to be bound thereby. No
amendment of this Agreement shall be effective until approved specifically by
(a) the Board of Trustees of the Trust, or by vote of a majority of the
outstanding shares of the Subject Fund, and (b) by vote of a majority of those
Trustees of the Trust who are not interested persons of any party to this
Agreement cast in person at a meeting called for the purpose of voting on such
approval.

12.  LIMITATION OF LIABILITY.

     It is expressly agreed that the obligations of the Trust hereunder shall
not be binding upon any of the trustees, shareholders, officers, agents or
employees of the Trust personally, but only bind the trust property of the
Trust, as provided in the Trust's Declaration of Trust.

13.  GOVERNING LAW.

     This agreement shall be construed in accordance with the laws of the
Commonwealth of Massachusetts and the applicable provisions of the 1940 Act and
rules thereunder.

14.  NOTICES.

     Notices and other communications required or permitted under this
Agreement shall be in writing, shall be deemed to be effectively delivered when
actually received, and may be delivered by US mail

and restrictions of said Fund, as set forth in the Subject Fund's current

restrictions. Advisers, as a sub-manager, will manage the investment and
reinvestment of the Subject Assets, and perform the functions set forth below,
subject to the overall supervision, direction, control and review of JHLICO and

regulations (including any applicable investment restrictions imposed by state
insurance laws and regulations or any directions or instructions, each as

     (a) advise the Subject Fund in connection with investment policy decisions
regarding the Subject Assets and, upon request, furnish the Trust with research,
economic and statistical data in connection with investments and investment
policies for the Subject Assets;

     (b) submit such reports and information as JHLICO or the Trust's Board of

delivery of securities and transfer of cash for the Subject Assets;

extent not maintained by the custodian, transfer agent or JHLICO;

for the Subject Assets;

     (g) as soon as practicable following the end of each calendar month,
provide JHLICO with written statements showing all transactions effected for the
Subject Assets during the month, a summary listing all investments held in the
Subject Assets as of the last day of the month, and such other information as

     (h) absent specific instructions to the contrary provided to it by JHLICO
and subject to its receipt of all necessary voting materials, vote all proxies
with respect to investments of the Subject Assets in accordance with Advisers'
proxy voting policy as most recently provided to JHLICO.

     On its own initiative, Advisers will apprise JHLICO and the Trust of
important political and economic developments materially affecting the
marketplace or the Subject Assets, and will furnish JHLICO and the Trust's Board
of Trustees from time to time such information as is appropriate for this
purpose. Advisers will also make its personnel available in Boston or other
reasonable locations as often as quarterly to discuss the Subject Assets and
Advisers' management thereof, to educate JHLICO sales personnel with respect
thereto, and for such other purposes as the Trust or JHLICO may reasonably
request.

     The Trust and JHLICO will provide timely information to Advisers regarding
such matters as purchases and redemptions of shares in the Subject Fund and the
cash requirements of, and cash available for investment in, the Subject Fund.
JHLICO will timely provide Advisers with copies of monthly accounting statements
for the Subject Fund, and such other information (including, without limitation,
reports concerning the classification of portfolio securities for purposes of
Subchapter M of the Internal Revenue Code of 1986, as amended (the "Code") and
Treasury Regulations Section 1.817) as may be reasonably necessary or
appropriate in order for Advisers to perform its responsibilities hereunder.


3.   ALLOCATION OF EXPENSES.

     Each party to this Agreement shall bear the costs and expenses of
performing its obligations hereunder. In this regard, the Trust specifically
agrees to assume the expense of:

     (e) brokerage commissions for transactions in the portfolio investments of
         the Trust and similar fees and charges for the acquisition,
         disposition, lending or borrowing of such portfolio investments;

     (f) custodian fees and expenses;

     (g) all taxes, including issuance and transfer taxes, and reserves for
         taxes payable by the Trust to federal, state or other governmental
         agencies; and

or any other agreement to which they are parties.
<PAGE>

                                      -4-

4.   SUB-ADVISORY FEES.

     For all of the services rendered with respect to the Subject Assets as
herein provided, JHLICO shall pay to Advisers a fee (for the payment of which
the Trust shall have no obligation or liability), based on the Current Net
Assets(as defined below) of the Subject Assets, as set forth in Schedule I
attached hereto and made a part hereof. Such fee shall be accrued daily and
payable monthly, as soon as practicable after the last day of each calendar
month. In the case of termination of this Agreement with respect to the Subject
Assets during any calendar month, the fee with respect to the Subject Assets
accrued to but excluding the date of termination shall be paid promptly
following such termination. For purposes of computing the amount of advisory fee
accrued for any day, "Current Net Assets" shall mean the net assets as of the
most recent preceding day for which the Subject Fund's net assets were computed.

5.   PORTFOLIO TRANSACTIONS.

     In connection with the investment and reinvestment of the Subject Assets,
Advisers is authorized to select the brokers or dealers that will execute
purchase and sale transactions for the Subject Assets and to use its best
efforts to obtain the best available price and most favorable execution with
respect to all such purchases and sales of portfolio securities for said Subject
Assets. Advisers shall maintain records adequate to demonstrate compliance with
this requirement. Subject to this primary requirement, and maintaining as its
first consideration the benefits to the Subject Fund and its shareholders,
Advisers shall have the right subject to the control of the Board of Trustees,
and to the extent authorized by the Securities Exchange Act of 1934, to follow a
policy of selecting brokers who furnish brokerage and research services to the
Subject Fund or to the Advisers, and who charge a higher commission rate to the
Subject Fund than may result when allocating brokerage solely on the basis of
seeking the most favorable price and execution. Advisers shall determine in good
faith that such higher cost was reasonable in relation to the value of the
brokerage and research services provided.

     Advisers will not receive any tender offer solicitation fees or similar
payments in connection with the tender of investments of any Fund.

6.   OWNERSHIP OF INFORMATION, RECORDS, AND CONFIDENTIALITY.

     Except for such records Advisers is required to maintain under the
Investment Advisers Act of 1940, as amended, the Trust shall own and control all
records maintained hereunder by Advisers on the Trust's behalf and, in the event
of termination of this Agreement with respect to the Subject Assets for any
reason, all records relating to the Subject Fund owned by the Trust shall be
promptly returned to the Trust, free from any claim or retention of rights by
Advisers, provided that (subject to the last paragraph of this Section 6)
Advisers may retain copies of such records. Advisers also agrees, upon request
of the Trust, promptly to surrender such books and records or, at its expense,
copies thereof, to the Trust or make such books and records available for audit
or inspection by representatives of regulatory authorities or other persons
reasonably designated by the Trust. Advisers further agrees to maintain, prepare
and preserve such books and records as it is required to as an investment
sub-adviser to the Trust in accordance with the 1940 Act and rules thereunder,
including but not limited to Rules 31a-1 and 31a-2, and to supply all such
information related to the Subject Fund as may be requested by any insurance
regulatory authorities in connection with such insurance authorities'
administration of insurance laws and regulations. Advisers shall supply the
Board of Trustees and officers of the Trust and JHLICO with all statistical
information regarding investments made on behalf of the Subject Assets which is
reasonably required by them and reasonably available to Advisers.
<PAGE>

                                      -5-

     Advisers shall not disclose or use any records or information obtained
pursuant hereto in any manner whatsoever except as expressly authorized herein,
and will keep confidential any information obtained pursuant hereto, and
disclose such information only if the Trust has authorized such disclosure, or
if such disclosure is expressly requested by applicable federal or state
regulatory authorities. Advisers shall provide reasonable notice to the Trust of
any such disclosure to applicable federal or state regulatory officials in
connection with any audit of the Subject Fund or the Trust, and in any event,
Advisers shall provide reasonable notice to the Trust of any threatened, pending
or final regulatory enforcement or other disciplinary action involving Advisers.

7.   LIABILITY; STANDARD OF CARE.

     Advisers shall be liable to JHLICO, the Trust or the Trust's shareholders
for losses resulting from any willful misfeasance, bad faith or negligence in
the performance of Advisers' duties or the reckless disregard of its obligations
and duties under this Agreement or the Investment Management Agreement. No
provision hereof shall be deemed to protect any trustee or officer of the Trust
against any such liability to which he might otherwise be subject by reason of
any willful misfeasance, bad faith or negligence in the performance his duties
or the reckless disregard of his obligations and duties. Adviser shall employ
only qualified personnel to manage the Subject Assets; shall comply with all
applicable laws and regulations in the discharge of its duties under this
Agreement; shall (as provided in Section 2 above) comply with the investment
policies, guidelines and restrictions of the Subject Fund and with the

JHLICO or the custodian concerning the classification of Fund securities for
such purposes) as a regulated investment company in accordance with subchapter M
of the Internal Revenue Code of 1986, as amended (the "Code"), and Treasury
Regulations Section 1.817-5(b); shall act at all times in the best interests of
the Trust; and shall discharge its duties with the care, skill, prudence and
diligence under the circumstances then prevailing that a prudent person acting

         receipt of such copy (or such other time as may be mutually agreed), to
         the manner in which its name and logo are used.

10.  AVOIDANCE OF INCONSISTENT POSITION.

     In connection with the purchase and sale of portfolio securities of the
Subject Assets, Advisers and its directors, officers and employees will not act
as principal or agent or receive any commission. Nothing in this Agreement,
however, shall preclude the combination of orders for the sale or purchase of
portfolio securities of the Subject Assets with those for other registered
investment companies managed by Advisers or its affiliates, if orders are
allocated in a manner deemed equitable by Advisers among the accounts and at a
price approximately averaged.

11.  AMENDMENT.

     No provision of this Agreement may be changed, waived, discharged or
terminated orally, but only by an instrument in writing. No amendment of this
Agreement shall be effective until approved specifically by (a) the Board of
Trustees of the Trust, or by vote of a majority of the outstanding shares of the
Subject Fund, and (b) by vote of a majority of those trustees of the Trust who
are not interested persons of any party to this Agreement cast in person at a
meeting called for the purpose of voting on such approval.

                      JOHN HANCOCK LIFE INSURANCE COMPANY
<PAGE>

                      SUB-INVESTMENT MANAGEMENT AGREEMENT

      AGREEMENT made as of the day of  , 2000 by and among John Hancock Variable
Series Trust I, a Massachusetts business trust (the "Trust"), Independence
Investment Associates, Inc., a Delaware corporation ("IIA"), and John Hancock
Life Insurance Company, a Massachusetts corporation ("JHLICO").

      WHEREAS, the Trust is organized and is engaged in business as an open-end
management investment company and is so registered under the Investment Company
Act of 1940 (the "1940 Act"); and

      WHEREAS, JHLICO and IIA are engaged in the business of rendering
investment advice under the Investment Advisers Act of 1940; and

      WHEREAS, the Trust is authorized to issue shares of capital stock in
separate classes with each such class representing interests in a separate
portfolio of securities and other assets; and

      WHEREAS, the Trust offers shares in several classes, one of which is
designated as the Growth & Income Fund, (together with all other classes
established by the Trust, the "Funds"), each of which pursues its investment
objectives through separate investment policies; and

      WHEREAS, the Trust has retained JHLICO to render investment management
services to the Trust pursuant to an Investment Management Agreement dated as of
April 12, 1988 (the "Investment Management Agreement"), pursuant to which it may
contract with one or more investment advisers as provided for herein;

      NOW, THEREFORE, WITNESSETH: That it is hereby agreed between the parties
hereto as follows:

1.    APPOINTMENT OF SUB-MANAGER

     (a) Subject Fund. IIA is hereby appointed and IIA hereby accepts the
         ------------
appointment to act as an investment adviser and manager to the Growth & Income
Fund (the "Subject Fund"), effective      , 2000, for the period and on the
                                     -----
terms herein set forth, for the compensation herein provided.
<PAGE>

                                     -12-

      (b) Additional Subject Funds. In the event that the Trust and JHLICO
          ------------------------
desire to retain IIA to render investment advisory services hereunder for any
other Fund, they shall so notify IIA in writing. If it is willing to render such
services, IIA shall notify the Trust in writing, whereupon such Fund shall
become a Subject Fund hereunder.

      (c) Independent Contractor. IIA shall for all purposes herein be deemed to
          ----------------------
be an independent contractor and shall, unless otherwise expressly provided or
authorized, have no authority to act for or be deemed an agent of the Trust.

2.  PROVISION OF INVESTMENT MANAGEMENT SERVICES.

      IIA will provide for such portion of the Subject Fund's assets as may be
designated to it by JHLICO from time to time (the "Subject Assets") a continuing
and suitable investment program consistent with the investment policies,
objectives and restrictions of said Fund, as furnished to IIA by JHLICO in
writing from time to time. IIA will manage the investment and reinvestment of
the the Subject Assets, and perform the functions set forth below, subject to
the overall supervision, direction, control and review of the Board of Trustees
of the Trust, JHLICO and, as in effect from time to time, the provisions of the
Trust's Declaration of Trust, Bylaws, prospectus, statement of additional
information (all as furnished to IIA by JHLICO in writing from time to time),
the 1940 Act and all other applicable laws and regulations (including any
applicable investment restrictions imposed by state insurance laws and
regulations or any directions or instructions, all as delivered to IIA in
writing by JHLICO or the Trust from time to time).

      IIA will have investment discretion with respect to the Subject Assets and
will, at its own expense:

           (a)    upon request, advise the Trust in connection with investment
decisions to be made by its Board of Trustees or any committee thereof regarding
the Subject Assets and furnish the Trust with research, economic and statistical
data in connection with investments and investment policies for the Subject
Assets;

          (b)    submit such reports relating to the valuation of the Subject
Assets as the Trust's Board of Trustees may reasonably request;
<PAGE>

                                     -13-

          (c)    place orders for purchases and sales of portfolio investments
for the Subject Assets;

          (d)    maintain and preserve the records relating to its activities
hereunder, including those records required by the 1940 Act to be maintained by
it and preserved by the Trust, to the extent not maintained by the Trust's
custodian, transfer agent or JHLICO; and

          (e)    subject to its receipt of all necessary voting materials, in
its discretion, as it deems advisable in the best interests of the Subject Fund,
vote, or cause to be voted, any or all proxies with respect to the Subject
Assets in accordance with IIA's proxy voting policy as most recently provided to
JHLICO.

      The Trust and JHLICO will provide timely information to IIA regarding such
matters as purchases and redemptions of shares with respect to the Subject
Assets and the cash requirements of, and cash available for investment in, the
Subject Assets, and all information (including, without limitation, reports
concerning the classification of Fund securities for purposes of Subchapter M of
the Internal Revenue Code and Treasury Regulations Section 1.817) as may be
reasonably necessary or appropriate in order for IIA to perform its
responsibilities hereunder. On its own initiative, IIA will apprise JHLICO and
the Trust of important developments materially affecting the Subject Assets and
will furnish JHLICO and the Trust's Board of Trustees from time to time such
information as is appropriate for this purpose.

3.    ALLOCATION OF EXPENSES.

      Each party to this Agreement shall bear the costs and expenses of
performing its obligations hereunder. In this regard, the Trust specifically
agrees, without limitation, to assume the expense of:

      (i) brokerage commissions for transactions in the portfolio investments of
the Subject Assets and similar fees, charges and expenses incurred in connection
with the acquisition, disposition, lending or borrowing of such portfolio
investments;

      (ii) all taxes, including issuance and transfer taxes, and reserves for
taxes payable by the Trust to federal, state or other governmental agencies; and

      (iii)  interest payable on the Trust's borrowings.
<PAGE>

                                     -14-

Nothing in this Agreement shall alter the allocation of expenses and costs
agreed upon between the Trust and JHLICO in the Investment Management Agreement
or any other agreement to which they are parties.

4.    SUB-ADVISORY FEES.

      For all of the services rendered as herein provided, JHLICO shall pay to
IIA a fee (for payment of which the Trust shall have no obligation or liability)
based on the Current Net Assets of the Subject Assets, as set forth in Schedule
I attached hereto and made a part hereof. The fee shall be accrued daily and
payable monthly, as soon as practicable after the last day of each calendar
month. In the case of termination of this Agreement with respect to the Subject
Assets during any calendar month, the fee with respect to such Subject Assets
accrued to termination shall be paid promptly following such termination.

      "Current Net Assets" of the Subject Assets for purposes of computing the
amount of advisory fee accrued for any day shall mean the net assets of the
Subject Assets as of the most recent preceding day for which the Subject Assets'
net assets were computed.

5.    FUND TRANSACTIONS.

      In connection with the investment and reinvestment of the assets of the
Subject Fund, IIA is authorized to select the brokers or dealers that will
execute purchase and sale transactions for the Subject Assets and to use its
best efforts to obtain best execution with respect to all such purchases and
sales of Fund securities for said Subject Assets. IIA shall maintain records
reasonably adequate to demonstrate compliance with this requirement. Subject to
this primary requirement, and maintaining as its first consideration the
benefits to the Subject Fund and its shareholders, IIA shall have the right
subject to the control of the Board of Trustees, and to the extent authorized by
the Securities Exchange Act of 1934, to follow a policy of selecting brokers who
furnish brokerage and research services to the Subject Fund or to IIA, and who
charge a higher commission rate to the Subject Fund than may result when
allocating brokerage solely on the basis of seeking the most favorable price and
execution. IIA shall determine in
<PAGE>

                                     -15-

good faith that such higher cost was reasonable in relation to the value of the
brokerage and research services provided.

      The fees payable to IIA by JHLICO hereunder shall be reduced by any tender
offer solicitation fees or similar payments received by IIA, in connection with
the tender of investments of any Subject Assets (less direct expenses incurred
by IIA in connection with obtaining such fees or payments), to the extent not
otherwise paid or credited to the Subject Fund.

6.    INFORMATION, RECORDS, AND CONFIDENTIALITY.

      The Trust shall own and control all records maintained hereunder by IIA on
the Trust's behalf and, in the event of termination of this Agreement with
respect to the Subject Fund for any reason, all records (or true and complete
copies thereof) relating to that Fund shall be promptly returned to the Trust,
free from any claim or retention of rights by IIA. IIA also agrees, upon request
of the Trust, promptly to surrender such books and records or, at its expense,
copies thereof, to the Trust or make such books and records available for
inspection by representatives of regulatory authorities or other persons
reasonably designated by the Trust. IIA further agrees to maintain, prepare and
preserve such books and records in accordance with the 1940 Act and rules
thereunder, including but not limited to, Rules 31a-1 and 31a-2 and to supply
all information in its possession or reasonably available to it, requested by
any insurance regulatory authorities to determine whether all insurance laws and
regulations are being complied with.

      IIA shall not disclose or use any records or information obtained pursuant
hereto in any manner whatsoever except as expressly authorized herein, and will
keep confidential any information obtained pursuant hereto, and disclose such
information only (i) to John Hancock Life Insurance Company, or to any other
person or entity that directly or indirectly owns all or substantially all of
the IIA's capital stock; (ii) if the Trust or JHLICO has authorized such
disclosure, or (iii) if such disclosure is expressly required by applicable
federal or state regulatory authorities or court proceedings.

          IIA shall supply the Board of Trustees and officers of the Trust and
JHLICO with all statistical information regarding investments which is
reasonably required by them and reasonably available to it.

                                     -16-

7.    LIABILITY; STANDARD OF CARE.

      No provision of this Agreement shall be deemed to protect IIA or JHLICO
against any liability to the Trust or its shareholders to which it might
otherwise be subject by reason of any willful misfeasance, bad faith or
negligence in the performance of its duties or the reckless disregard of its
obligations and duties under this Agreement or the Investment Management
Agreement, as applicable. Nor shall any provision hereof be deemed to protect
any trustee or officer of the Trust against any such liability to which he might
otherwise be subject by reason of any willful misfeasance, bad faith or
negligence in the performance of his duties or the reckless disregard of his
obligations and duties. IIA shall employ only qualified personnel to manage the
Subject Assets; shall comply with all applicable laws and regulations in the
discharge of its duties under this Agreement (provided that copies of any
applicable investment restrictions imposed by state insurance laws and
regulations shall be furnished to IIA by JHLICO); shall (as provided in Section
2 above) comply with the investment policies, guidelines and restrictions of the
Subject Fund and with the provisions of the Trust's Declaration of Trust,
Bylaws, prospectus and statement of additional information, all as furnished to
IIA by JHLICO in writing from time to time; shall manage the Subject Assets
(subject to the receipt of, and based upon the information contained in,
periodic reports from JHLICO or the custodian concerning the classification of
Fund securities for such purposes) as a regulated investment company in
accordance with subchapter M of the Internal Revenue Code of 1986, as amended
(the "Code"), and Treasury Regulations Section 1.817-5(b); shall act in its
management of the Subject Assets in the best interests of the Trust, subject
however to its duties to other clients as described in Section 9 below; and
shall discharge its duties with the care, skill, prudence and diligence under
the circumstances then prevailing that a prudent person acting in a like
capacity and familiar with such matters would use in the conduct of a similar
enterprise. However, IIA shall not be obligated to perform any service not
described in this Agreement, and shall not be deemed by virtue of this Agreement
to have made any representation or warranty that any level of investment
performance or level of investment results will be achieved.

8.    DURATION AND TERMINATION OF THIS AGREEMENT.

      (a) Duration. This Agreement shall become effective with respect to the
          --------
Growth & Income Fund on the date set forth in Section 1(a) hereof and, with
respect to any additional Subject Fund, on the date of receipt by the Trust of
notice from IIA in accordance with Paragraph 1(b) hereof that it is willing to
serve with respect to such Fund. Unless terminated as herein provided, this
Agreement shall remain in full force and effect for two years from the date
hereof with respect to the initial Subject Fund and, with respect to each
additional Subject Fund, until two years following the date on which such Fund
becomes a Subject Fund hereunder, and shall continue in full force and effect
thereafter with respect to each Subject Fund so long as such continuance with
respect to any such Fund is approved at least annually (a) by either the Board
of Trustees of the Trust or by vote of a majority of the outstanding voting
shares of such Fund, and (b) in either event by the vote of a majority of the
trustees of the Trust who are not parties to this Agreement or "interested
persons" of any such party, cast in person at a meeting called for the purpose
of voting on such approval.

      Any approval of this Agreement by the holders of a majority of the
outstanding shares of any Subject Fund shall be effective to continue this
Agreement with respect to any such Fund notwithstanding (A) that this Agreement
has not been approved by the holders of a majority of the outstanding shares of
any other Fund affected hereby, and (B) that this Agreement has not been
approved by the vote of a majority of the outstanding shares of the Trust,
unless such approval shall be required by any other applicable law or otherwise.
The terms "assignment," "vote of a majority of the outstanding shares" and
"interested person," when used in this Agreement, shall have the respective
meanings specified in the 1940 Act and rules thereunder.

      (b) Termination. This Agreement may be terminated with respect to any
          -----------
Subject Fund at any time, without payment of any penalty, by the Trust pursuant
to a vote of the trustees of the Trust or a vote of a majority of the
outstanding shares of such Fund, which termination shall be effective
immediately upon delivery of notice thereof to IIA and JHLICO. This Agreement
may be terminated by IIA on at least sixty days' prior written notice to the
Trust and JHLICO, or by JHLICO on at least sixty days' prior written
<PAGE>

                                     -18-

notice to the Trust and IIA. Transactions already entered into by IIA but not
yet settled at the time of any such termination shall settle for the account of
the Trust.

      (c) Automatic Termination. This Agreement shall automatically and
          ---------------------
immediately terminate in the event of its assignment or if the Investment
Management Agreement is terminated.

9.    SERVICES NOT EXCLUSIVE.

      The services of IIA to the Trust are not to be deemed exclusive and it
shall be free to render similar services to others so long as its services
hereunder are not impaired thereby. It is specifically understood that
directors, officers and employees of IIA and of its subsidiaries and affiliates
may continue to engage in providing portfolio management services and advice to
other investment companies, whether or not registered, and other investment
advisory clients.

      Nothing in this Agreement shall limit or restrict IIA or any of its
officers, affiliates or employees from buying, selling or trading in any
securities for its or their own accounts; provided, however, that no such person
shall purchase securities from or sell securities to the Subject Fund except as
permitted under applicable laws and regulations, including without limitation
the 1940 Act and the Investment Advisers Act of 1940, and the rules and
regulations thereunder. The Trust acknowledges that IIA and its officers,
affiliates and employees, and its and their other clients, may at any time have,
acquire, increase, decrease or dispose of positions in investments which are at
the same time being acquired or disposed of under this Agreement. IIA shall have
no obligation to acquire for the Subject Fund a position in any investment which
IIA, its officers, affiliates or employees may acquire for their own accounts or
for the account of another client, if in the sole discretion of IIA it is not
feasible or desirable to do so.

10.   AVOIDANCE OF INCONSISTENT POSITION.

      In connection with the purchase and sale of portfolio securities of the
Subject Assets, IIA and its directors, officers and employees will not act as
principal or agent or receive any commission, except as may be permitted under
applicable laws and regulations and the policies and procedures of the Trust in
<PAGE>

                                     -19-

effect from time to time. Nothing in this Agreement, however, shall preclude the
combination of orders for the sale or purchase of portfolio securities of the
Subject Assets with those for other accounts managed by IIA or its affiliates,
if orders are allocated in a manner deemed equitable by IIA among the accounts
and at a price approximately averaged.

11.   AMENDMENT.

      No provision of this Agreement may be changed, waived, discharged or
terminated orally, but only by an instrument in writing signed by a duly
authorized officer of the party or parties intending to be bound thereby. No
amendment of this Agreement shall be effective until approved specifically by
(a) the Board of Trustees of the Trust, or by vote of a majority of the
outstanding shares of the Subject Fund, and (b) by vote of a majority of those
Trustees of the Trust who are not interested persons of any party to this
Agreement cast in person at a meeting called for the purpose of voting on such
approval.

12.   LIMITATION OF LIABILITY.

      It is expressly agreed that the obligations of the Trust hereunder shall
not be binding upon any of the trustees, shareholders, officers, agents or
employees of the Trust personally, but only bind the trust property of the
Trust, as provided in the Trust's Declaration of Trust.

13.   GOVERNING LAW.

      This agreement shall be construed in accordance with the laws of the
Commonwealth of Massachusetts and the applicable provisions of the 1940 Act and
rules thereunder.

14.   NOTICES.

other purposes as the Trust or JHLICO may reasonably request.

such matters as purchases and redemptions of shares in the Subject Funds and the
cash requirements of, and cash available for investment in, the Subject Funds.
JHLICO will timely provide Advisers with copies of monthly accounting statements
for the Subject Funds, and such other information (including, without
limitation, reports concerning the classification of portfolio securities of the
Subject Funds for purposes of Subchapter M of the Internal Revenue Code and
Treasury Regulations Section 1.817) as may be reasonably necessary or
appropriate in order for Advisers to perform its responsibilities hereunder.

shall not be expected or responsible to perform any service or function with
respect thereto, except as is expressly stated in this Agreement.

3.   ALLOCATION OF EXPENSES.

     Each party to this Agreement shall bear the costs and expenses of
performing its obligations hereunder. In this regard, the Trust specifically
agrees to assume the expense of:

     (i)  brokerage commissions for transactions in the portfolio investments of
          the Trust and similar fees and charges for the acquisition,
          disposition, lending or borrowing of such portfolio investments;

     (j)  custodian fees and expenses;

     (k)  all taxes, including issuance and transfer taxes, and reserves for
          taxes payable by the Trust to federal, state or other governmental
          agencies; and

     (l)  interest payable on the Trust's borrowings.

Nothing in this Agreement shall alter the allocation of expenses and costs
agreed upon between the Trust and JHLICO in the Investment Management Agreement
or any other agreement to which they are parties.

4.   SUB-ADVISORY FEES.

     For all of the services rendered with respect to the Subject Funds as
herein provided, JHLICO shall pay to Advisers a fee (for the payment of which
the Trust shall have no obligation or liability), based on the Current Net
Assets (as defined below) of the Subject Funds, as set forth in Schedule I
attached hereto and made a part hereof. Such fee shall be accrued daily and
payable monthly, as soon as practicable after the last day of each calendar
month. In the case of termination of this Agreement with respect to a Subject
Fund during any calendar month, the fee with respect to such Fund accrued to but
excluding the date of termination shall be paid promptly following such
termination. For purposes of computing the amount of advisory fee accrued for
any day, "Current Net Assets" shall mean a Subject Fund's net assets as of the
most recent preceding day for which that Subject Fund's net assets were
determined by the Subject Fund's Custodian or by the Subject Fund's
administrator, as the case may be.

5.   FUND TRANSACTIONS.

     In connection with the investment and reinvestment of the assets of a
Subject Fund, Advisers is authorized to select the brokers or dealers that will
execute purchase and sale transactions for the Fund and to use its best efforts
to obtain the best available price and most favorable execution with respect to
all such purchases and sales of portfolio securities for said Fund. Advisers
shall maintain records adequate to demonstrate compliance with this requirement.
Subject to this primary requirement, and maintaining as its first consideration
the benefits to the Subject Fund and its shareholders, Advisers shall have the
right subject to the control of the Board of Trustees, and to the extent
authorized by the Securities Exchange Act of 1934, to follow a policy of
selecting brokers who furnish brokerage and research services to the Subject
Fund or to the Advisers, and who charge a higher commission rate to the Subject
Fund than may result when allocating brokerage solely on the basis of seeking
the most favorable price and execution. Advisers shall determine in good faith
that such higher cost was reasonable in relation to the value of the brokerage
and research services provided.

     Advisers will not receive any tender offer solicitation fees or similar
payments in connection with the tender of investments of any Fund.

                                      -5-

6.   OWNERSHIP OF INFORMATION, RECORDS, AND CONFIDENTIALITY.

Advisers on the Trust's behalf and, in the event of termination of this
Agreement with respect to any Subject Fund for any reason, upon request of the
Trust or its designee, all records relating to that Fund shall be promptly
returned to the Trust, free from any claim or retention of rights by Advisers,
provided that (subject to the last paragraph of this Section 6) Advisers may
retain copies of such records. Advisers also agrees, upon request of the Trust,
promptly to surrender such books and records or, at its expense, copies thereof,

representatives of regulatory authorities or other persons reasonably designated

limited to Rules 31a-1 and 31a-2, and supply all information requested by any
insurance regulatory authorities to determine whether all insurance laws and
regulations are being complied with. Advisers shall supply the Board of Trustees
and officers of the Trust and JHLICO with all statistical information regarding
investments which is reasonably required by them and reasonably available to
Advisers.

     Advisers shall not disclose or use any records or information obtained
pursuant hereto in any manner whatsoever except as expressly authorized herein,
and will keep confidential any information obtained pursuant hereto, and
disclose such information only if the Trust has authorized such disclosure, or
(after reasonable notice to the Trust) if such disclosure is expressly requested
by applicable federal or state regulatory authorities.

7.   LIABILITY; STANDARD OF CARE.

     No provision of this Agreement shall be deemed to protect Advisers against
any liability to the Trust or its shareholders to which it might otherwise be
subject by reason of any willful misfeasance, bad faith or negligence in the
performance of its duties or the reckless disregard of its obligations and
duties under this Agreement. No provision of this Agreement shall be deemed to
protect JHLICO against any liability to the Trust or its shareholders to which
it might otherwise be subject by reason of any willful misfeasance, bad faith or
negligence in the performance of its duties or the reckless disregard of its
obligations and duties under the Investment Management Agreement. Nor shall any
provision hereof be deemed to protect any trustee or officer of the Trust

or the reckless disregard of his obligations and duties. Advisers shall employ
only qualified personnel to manage a Subject Fund; shall comply with all
applicable laws and regulations in the discharge of its duties under this

for such purposes) as a regulated investment company in accordance with
subchapter M of the Internal Revenue Code of 1986, as amended (the "Code"), and
Treasury Regulations Section 1.817-5(b); shall act at all times in the best
interests of the Trust; and shall discharge its duties with the care, skill,
prudence and diligence under the circumstances then prevailing that a prudent

perform any service not described in this Agreement, and shall not be deemed by
virtue of this Agreement to have made any representation or warranty that any

          ---------------------
          immediately terminate in the event of its assignment (other than as
          permitted pursuant to Section 15 below) or if the Investment
          Management Agreement is terminated.

9.   SERVICES NOT EXCLUSIVE; USE OF ADVISERS' NAME AND LOGO.

     (e)  The services of Advisers to the Trust are not to be deemed exclusive
          and it shall be free to render similar services to others so long as
          its services hereunder are not impaired thereby. It is specifically
          understood that directors, officers and employees of Advisers and of
          its subsidiaries and affiliates may continue to engage in providing
          Fund management services and advice to other investment companies,
          whether or not registered, and other investment advisory clients.

     (f)  The parties agree that the name "Capital Guardian Trust Company", the
          names of the Advisers' affiliates within The Capital Group Companies,
          Inc. as listed on Schedule II to this Agreement, and any logo or trade
          or service mark (including but not limited to the American Funds Group
          of mutual funds) (collectively referred to as the "Protected
          Information"), are the valuable property of the Advisers and its
          affiliates. The Trust and JHLICO shall have the right to use the
          Protected Information provided that, prior to distribution of any
          materials which refer to Advisers or the Protected Information, JHLICO
<PAGE>

                                      -7-

          shall consult with Advisers and shall furnish to Advisers a copy of
          such materials. Advisers agrees to cooperate with JHLICO and to review
          such materials promptly. JHLICO shall not distribute such materials if
          Advisers reasonably objects in writing, within five (5) business days
          of its receipt of such copy (or such other time as may be mutually
          agreed), to the manner in which its name and the Protected Information
          are used.

10.  AVOIDANCE OF INCONSISTENT POSITION.

     In connection with the purchase and sale of portfolio securities of a
Subject Fund, Advisers and its directors, officers and employees will not act as
principal or agent or receive any commission. Nothing in this Agreement,
however, shall preclude the combination of orders for the sale or purchase of
portfolio securities of the Subject Fund with those for other accounts by
Advisers or its affiliates, if orders are allocated in a manner deemed equitable
by Advisers among the accounts and at a price approximately averaged.

11.  AMENDMENT.

     No provision of this Agreement may be changed, waived, discharged or
terminated orally, but only by an instrument in writing agreed to by the parties
hereto. Additionally, no amendment of this Agreement shall be effective with
respect to any Fund until approved specifically by (a) the Board of Trustees of
the Trust, or by vote of a majority of the outstanding shares of that Fund, and
(b) by vote of a majority of those trustees of the Trust who are not interested
persons of any party to this Agreement cast in person at a meeting called for
the purpose of voting on such approval.

12.  LIMITATION OF LIABILITY.

     It is expressly agreed that the obligations of the Trust hereunder shall
not be binding upon any of the trustees, shareholders, officers, agents or
employees of the Trust personally, but only bind the trust property of the
Trust, as provided in the Trust's Declaration of Trust.

13.  NOTICES

     Notices and other communications required or permitted under this Agreement
shall be in writing, shall be deemed to be effectively delivered when actually
received, and may be delivered by US mail (first class, postage prepaid), by
facsimile transmission, by hand or by commercial overnight delivery service,

          PROPOSALS 1C, 2C, 3B and 4B -- SUMMARY OF CURRENT INVESTMENT
                             MANAGEMENT AGREEMENTS

     The current investment management agreements between the Trust and John
Hancock are summarized below.

     Pursuant to the investment management agreements, John Hancock advises each
Fund in connection with policy decisions; provides administration of day-to-day
operations; provides personnel, office space, equipment and supplies for the
Fund; maintains records required by the Investment Company Act of 1940; and
supervises activities of the Fund's sub-investment manager(s), if any.

     For its investment management and advisory services, John Hancock is paid a
fee by each Fund at a specified rate that will vary by Fund.

     The investment management agreements also provide that for any fiscal year
in which the normal operating costs and expenses of Fund, exclusive of its
investment advisory fees, interest, brokerage commissions, taxes and
extraordinary expenses outside the control of John Hancock, exceed 0.10% of the
Fund's average daily net assets, John Hancock will reimburse the Fund promptly
after the end of the fiscal year in an amount equal to such excess.

     Under the investment management agreements, John Hancock also pays the
compensation of Trust officers and employees and the expenses of clerical
services relating to the administration of the Trust. The Trust bears all of its
expenses not specifically assumed by John Hancock. These include, but are not
limited to, taxes, custodian and auditing fees, brokerage commissions, advisory
fees, the compensation of unaffiliated Trustees, the cost of the Trust's
fidelity bond, the cost of printing and distributing to Shareholders the Trust's
annual and semi-annual reports, the cost of printing, distributing to
Shareholders, and tabulating proxy materials, compensation paid for certain
accounting, valuation and compliance services, legal fees and expenses, any
securities registration expenses, any organizational expenses, association dues
and any other expenses related to the Trust's operations.

     John Hancock also indemnifies each member of the Board of Trustees against
losses by reason of failure (other than through willful misfeasance, bad faith,
gross negligence or reckless disregard of duties) to take any action relating to
the investment or reinvestment of assets in the Trust, including failure to seek
or retain investment advice or management in addition to or in place of that
provided by John Hancock or the sub-investment managers.

     Unless modified or terminated, the investment management agreement will
continue with respect to the Fund from year to year but only so long as such
continuance is specifically approved at least annually by (a) a majority of the
Board of Trustees who are not interested persons of JHVLICO, John Hancock or the
Trust, cast in person at a meeting called for the purpose of voting on such
approval, and (b) either a vote of the Board of Trustees or a majority of the
outstanding voting shares of the Fund. The investment management agreement also
provides that it may, on 60 days' notice, be terminated at any time without
penalty by the Board of Trustees, by majority vote of the outstanding voting
shares of the Fund, or by John Hancock. The investment management agreement
automatically terminates in the event of its assignment.

                           IMPORTANT SPECIAL NOTICE!
                           =========================

        Proposal 1A and Proposal 3 in the enclosed proxy materials would
raise the investment advisory fees for the Growth & Income Fund and the Active
Bond Fund, respectively, if approved by the shareholders. However, our records
indicate that you, or someone in your household, purchased a John Hancock
variable life insurance policy that includes a special overall expense
limitation. That special limitation protects the policy from the effects of such
investment advisory fee increases. Such policies were issued sometime prior to
1987 and are hereafter referred to as "restricted policies". If Proposals 1A and
3 are approved by shareholders, we will make special adjustments so that your
restricted policy (and its policy values) will be the same as if the fee
increases had never taken place. No other policies will receive those
adjustments.

        Proposals IA and 3 will be voted on by owners of all variable life
insurance policies and variable annuity contracts that are participating in the
Growth & Income Fund and/or Active Bond Fund, whether or not the policy or
contract provides the same kind of protection that is afforded under your
restricted policy.

        Therefore, as the owner of a restricted policy, you have a particular
interest in voting FOR Proposal 1A and Proposal 3 because you will receive the
benefits of the Proposals while being protected from the effects of the
increases in fees.
