                                 _______________

               JOHN HANCOCK INTERMEDIATE MATURITY GOVERNMENT FUND

                                  a series of
                             John Hancock Bond Fund

                                   PROSPECTUS      
                                 _______________
                                                                 
     This Proxy Statement and Prospectus sets forth the information you should
know before voting on the proposed reorganization of John Hancock Intermediate
Government Trust ("Intermediate Government Trust") into John Hancock
Intermediate Maturity Government Fund ("Intermediate Maturity Fund") (formerly,
John Hancock Adjustable U.S. Government Trust ("Adjustable Government Trust")).
Please read it carefully and retain it for future reference.  Intermediate
Government Trust and Intermediate Maturity Fund are each series of John Hancock
Bond Fund, a Massachusetts business trust (the "Trust").

     This Proxy Statement and Prospectus is accompanied by the Preliminary
Prospectus of John Hancock Intermediate Maturity Government Fund (formerly,
Adjustable Government Trust) for Class A and Class B shares, dated July 19, 1995
and subject to completion.  Information about Intermediate Government Trust's
Class A and Class B shares is incorporated by reference to the Intermediate
Government Trust Prospectus which is available at no charge upon request to
Intermediate Maturity Fund at 1-800-225- 5291.

     A Statement of Additional Information dated July 21, 1995 relating to this
Proxy Statement and Prospectus, and containing additional information about each
of Intermediate Maturity Fund and Intermediate Government Trust, including
historical financial statements, is on file with the Securities and Exchange
Commission ("SEC").  It is available, upon telephone request and at no charge at
the toll-free number stated above, from Intermediate Maturity Fund.  The
Statement of Additional Information is incorporated by reference into this
Prospectus.

     This Proxy Statement and Prospectus relates to Class A and Class B shares
of beneficial interest, par value of $0.01 per share (collectively, the
"Intermediate Maturity Fund Shares"), of Intermediate Maturity Fund which will
be issued in exchange for


<PAGE>   3

all of Intermediate Government Trust's assets.  In exchange for these assets,
Intermediate Maturity Fund will also assume all of the liabilities of
Intermediate Government Trust.

     The Intermediate Maturity Fund Class A Shares issued to Intermediate
Government Trust for distribution to Intermediate Government Trust's Class A
shareholders will have an aggregate net asset value equal to that of
Intermediate Government Trust's Class A shares.  The Intermediate Maturity Fund
Class B Shares issued to Intermediate Government Trust for distribution to
Intermediate Government Trust's Class B shareholders will have an aggregate net
asset value equal to that of Intermediate Government Trust's Class B shares. The
asset values of Intermediate Government Trust and Intermediate Maturity Fund
will be determined at the close of business (4:00 p.m. Eastern Time) on the
Closing Date (as defined below) for purposes of the proposed reorganization.

     Following the receipt of Intermediate Maturity Fund Shares (1) Intermediate
Government Trust will be liquidated, (2) the Intermediate Maturity Fund Shares
will be distributed to Intermediate Government Trust's shareholders pro rata in
exchange for their shares of Intermediate Government Trust and (3) Intermediate
Government Trust will be terminated.  Consequently, Class A Intermediate
Government Trust shareholders will become Class A shareholders of Intermediate
Maturity Fund, and Class B Intermediate Government Trust shareholders will
become Class B shareholders of Intermediate Maturity Fund.  These transactions
are collectively referred to in this Proxy Statement and Prospectus as the
"Reorganization."  The Reorganization is being structured as a tax-free
reorganization so that, in the opinion of tax counsel, no gain or loss will be
recognized by Intermediate Maturity Fund, Intermediate Government Trust or the
shareholders of Intermediate Government Trust.  The terms and conditions of this
transaction are more fully described in this Proxy Statement and Prospectus, and
in the Agreement and Plan of Reorganization that is attached as EXHIBIT A.

     Intermediate Maturity Fund is a diversified series of the Trust, an
open-end management investment company organized as a Massachusetts business
trust in 1984.  In connection with the Reorganization, the Trustees have
proposed several matters for consideration by the shareholders of Intermediate
Maturity Fund including proposals to abolish the Fund's master/feeder structure
and to change the Fund's investment objective and an investment restriction to
permit the Fund to be managed as an intermediate maturity government fund rather
than as an adjustable rate government fund.  The Trustees have also approved the
change of the Fund's name to: John Hancock Intermediate Maturity Government
Fund.  If the shareholders of Intermediate Maturity Fund do not approve the
proposed changes, the transactions contemplated by the Reorganization will not
proceed as described.

     Intermediate Maturity Fund seeks to achieve a high level of current income,
consistent with the preservation of capital and maintenance of liquidity.
Intermediate Maturity Fund seeks to obtain this objective by investing primarily
(at least 65% of its total assets) in U.S. Government securities, including
mortgage- backed securities issued or guaranteed by U.S. Government agencies and
medium-term debt obligations of governmental issuers.  Under normal market
conditions, the Fund maintains a weighted average remaining maturity or
remaining average life of three to ten years.
    

     The principal place of business of both Intermediate Maturity Fund and
Intermediate Government Trust is at 101 Huntington Avenue, Boston, Massachusetts
02199.  Their toll-free telephone number is 1-800-225-5291.

     SHARES OF INTERMEDIATE MATURITY FUND ARE NOT DEPOSITS OR OBLIGATIONS OF, OR
GUARANTEED OR ENDORSED BY, ANY BANK OR OTHER DEPOSITORY INSTITUTION, AND THE
SHARES OF INTERMEDIATE MATURITY FUND ARE NOT FEDERALLY INSURED BY THE FEDERAL
DEPOSIT INSURANCE CORPORATION, THE FEDERAL RESERVE BOARD OR ANY OTHER GOVERNMENT
AGENCY.

AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION NOR HAS THE
SECURITIES AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION PASSED
UPON THE ACCURACY OR ADEQUACY OF THIS PROSPECTUS.  ANY REPRESENTATION TO THE
CONTRARY IS A CRIMINAL OFFENSE.

Meeting.  The purposes of the Meeting are set forth in the accompanying Notice
of Special Meeting of Shareholders.

     This Proxy Statement and Prospectus includes and incorporates by reference

"Fund" and collectively, the "Funds") will each bear its own fees and expenses
in connection with the Reorganization discussed in this Proxy Statement and
Prospectus.
    

     The information concerning Intermediate Government Trust and Intermediate
Maturity Fund in this Proxy Statement and Prospectus has been supplied by the
Trust.

                                    SUMMARY

     The following is a summary of certain information contained elsewhere in
this Proxy Statement and Prospectus.  The summary is qualified by reference to
the more complete information contained in this Proxy Statement and Prospectus,
and in the EXHIBITS attached to or included with this document.  Please read
this entire Proxy Statement and Prospectus carefully.

REASONS FOR THE PROPOSED REORGANIZATION

   
     The Trust's Board of Trustees has determined that the proposed
Reorganization is in the best interests of Intermediate Government Trust and its
shareholders.  In making this determination, the Trustees considered several
relevant factors, including (1) the fact that the investment objectives and
policies of Intermediate Government Trust and Intermediate Maturity Fund are
substantially identical, (2) the likelihood that the Reorganization will result
in improved economies of scale and a corresponding decrease in the expenses
currently borne by Intermediate Government Trust's shareholders and (3) the fact
that combining the Funds' assets into a single portfolio will enable
Intermediate Maturity Fund to achieve greater diversification than Intermediate
Government Trust is now able to achieve.  The Board of Trustees believes that
the Intermediate Maturity Fund Shares received in the Reorganization will
provide existing Intermediate Government Trust shareholders with substantially
the same investment advantages that they currently enjoy at a comparable level
of risk.  Shareholders of both Funds may benefit from a fund offering greater
diversification in its investment portfolio as a result of the larger asset
base.  Greater diversification may reduce the negative effect which the adverse
performance of any one security may have on the performance of the entire
portfolio. For a more detailed discussion of the reasons for the proposed

      B Rule 12b-1 fees to 0.90% of average net assets attributable to Class B
      until December 31, 1996, after which such fees may be increased to as much
      as 1.00% of such assets and total fund operating expenses would be 2.25%
      of such assets.

   *  The amount of the 12b-1 fee used to cover service expenses will be up to
      0.25% of the Class's average net assets, and the remaining portion will be
      used to cover distribution expenses.  The Fund has determined to pay Class
      B Rule 12b-1 fees to 0.90% of average net assets attributable to Class B
      until December 31, 1996, after which such fees may be increased to as much
      as 1.00% of such assets and total fund operating expenses would be 2.08%
      of such assets.
    

   
  **  Other expenses include transfer agent, legal, audit, custody and other
      expenses.
    

     If the Reorganization is consummated, the actual total operating expenses
of Class A and Class B shares of Intermediate Maturity Fund may vary from the
pro forma operating expenses

COMPARISON OF INVESTMENT OBJECTIVES AND POLICIES OF INTERMEDIATE
GOVERNMENT TRUST AND INTERMEDIATE MATURITY FUND

     Intermediate Government Trust:  The investment objective of Intermediate
Government Trust is to achieve a high level of current income, consistent with
preservation of capital and maintenance of liquidity.  The Fund invests
primarily in U.S. Government securities, with an emphasis on mortgage-backed
securities issued by U.S. Government agencies.  Under normal market conditions
the Fund maintains a weighted average maturity or average life of one to ten
years.  The Fund may invest in mortgage-related derivatives, including
collateralized mortgage obligations ("CMOs") and stripped mortgage-backed
securities ("SMBS").  It may also invest in asset-backed securities, and enter
into mortgage dollar rolls, interest rate futures contracts and options on
futures.

   
     Intermediate Maturity Fund:  The investment objective of Intermediate
Maturity Fund also is to achieve a high level of current income, consistent with
preservation of capital and maintenance of liquidity.  The Fund invests
primarily (at least
    


                                      -6-
<PAGE>   13



   
65% of its total assets) in U.S. Government securities, including mortgage
backed securities issued or guaranteed by U.S. Government agencies and
medium-term debt obligations of governmental issuers. Under normal market
conditions, the Fund maintains a weighted average remaining maturity or
remaining average life of three to ten years.  The Fund invests in
mortgage-related derivatives, including CMOs and SMBS.  The remainder of the
Fund's assets may be invested in other U.S. government securities and in asset-
backed securities and debt obligations of corporate issuers each of which is
rated in the highest rating category by a nationally recognized statistical
rating organization or, if unrated, determined by the Adviser to be of
comparable quality.  The Fund may enter into mortgage dollar rolls and engage in
hedging transactions in futures contracts and options on these futures.
    

     Intermediate Government Trust's investment objective is fundamental and may
not be changed without shareholder approval. Intermediate Maturity Fund's
investment objective is non- fundamental and may be changed by a vote of the
Fund's Board of Trustees.  Prior to the implementation of a change to the Fund's
investment objective, the Fund's prospectus and statement of additional
information will be revised or supplemented.

   
     In considering whether to approve the Reorganization, you should consider
any differences between the two Funds' investment policies and whether an
investment in Intermediate Maturity Fund is a suitable investment for you.  For
a discussion of the risks associated with an investment in the Funds, see "Risk
Factors and Special Considerations."

FORM OF ORGANIZATION

     Intermediate Government Trust and Intermediate Maturity Fund are two
separate series of the Trust, a Massachusetts business trust organized in 1984.
Both Funds have authorized and outstanding two classes of shares:  Class A and
Class B.

     Each share of a series of the Trust represents an equal proportionate
interest in the assets belonging to that series. The liabilities attributable to
each series are not charged against the assets of the other series of the Trust.
Shares of each series and the other series of the Trust are voted separately
with respect to matters pertaining to that series, but all shares vote together
for the election of Trustees and the ratification of independent accountants.

     The shares of each class of Intermediate Government Trust and Intermediate
Maturity Fund represent an interest in the same portfolio of investments of that
Fund.  Except as stated below, each class of each Fund has equal rights as to
voting, redemption, dividends and liquidation.  Each class bears different
distribu- tion and transfer agent fees and may bear other expenses properly
attributable to that class.  Class A and Class B shareholders of each Fund have
exclusive voting rights with regard to the Rule 12b-1 distribution plan covering
their class of shares.

SALES CHARGES AND DISTRIBUTION AND SERVICES FEES

   
     Class A Shares.  Intermediate Government Trust and Intermediate Maturity
Fund impose an initial sales charge on Class A shares as described above under
the caption, "The Funds' Expenses."  An initial sales charge does not apply to
Class A shares acquired through the reinvestment of dividends from net
investment income or capital gain distributions.
    


                                      -9-
<PAGE>   16




     Class A shares of Intermediate Government Trust acquired by Intermediate
Maturity Fund's Class A shareholders pursuant to the Reorganization will not be
subject to any initial sales charge or CDSC.  However, the CDSC imposed upon
certain redemptions within one year of purchase will continue to apply to the
Class A shares of Intermediate Maturity Fund issued in the Reorganization.  The
holding period for determining the application of this CDSC will be calculated
from the date the Intermediate Government Trust Class A shares were originally
issued.

     Class B Shares.  Intermediate Government Trust and Intermediate Maturity
Fund do not impose an initial sales charge on Class B shares.  However, Class B
shares redeemed within a specified number of years of purchase will be subject
to a CDSC at the rates set forth below.  This CDSC will be assessed on an amount
equal to the lesser of the current market value or the original purchase cost of
the Class B shares being redeemed. Accordingly, Class B shareholders will not be
assessed a CDSC on increases in account value above the initial purchase price,
including shares derived from reinvested dividends.  The amount of the CDSC, if
any, will vary depending on the number of years from the time the Class B shares
were purchased until the time they are redeemed, as follows:

     Class B shares of Intermediate Maturity Fund acquired by Intermediate
Government Trust's Class B shareholders pursuant to the Reorganization will not
be subject to any CDSC at the time of the Reorganization.  However, these shares
will remain subject to the original CDSC applicable when you redeem those
shares.  The CDSC schedule described above with respect to Class B shares of
Intermediate Maturity Fund will not apply to Class B shares of Intermediate
Maturity Fund that you acquire in the Reorganization. For purposes of computing
the CDSC payable upon redemption of Class B shares of Intermediate Maturity Fund
acquired by


                                      -10-

Intermediate Government Trust's Class B shareholders pursuant to the
Reorganization and the automatic conversion of Class B shares into Class A
shares, the holding period of the Intermediate Government Trust Class B shares
will be added to that of the Intermediate Maturity Fund Class B shares acquired
in the Reorganization.

     Distribution and Service Fees.  Both Funds have adopted distribution plans
pursuant to Rule 12b-1 under the Investment Company Act of 1940, as amended (the
"Investment Company Act"). Under these plans, each Fund may pay fees to John
Hancock Funds, Inc. ("John Hancock Funds"), the distributor of the Funds'
shares, to reimburse distribution and service expenses in connection with Class
A shares.  These fees are payable at an annual rate of up to 0.25% of the
average daily net assets attributable to the Class A shares of Intermediate
Government Trust and Intermediate Maturity Fund, respectively.

     In addition, under the plans, each Fund may pay fees to John Hancock Funds
to reimburse it for distribution and service expenses in connection with Class B
shares.  These fees are payable at an annual rate of up to 1.00% of each Fund's
average daily net assets attributable to its Class B shares.  As of the date of
this Proxy Statement and Prospectus, Intermediate Maturity Fund has determined
to temporarily limit the fee paid by Class B shares of that Fund to 0.90% of
these assets.  Of these fees, up to 0.25% may be for service expenses and up to
0.75% will be for distribution expenses.  With respect to Class B shares only,
if John Hancock Funds is not fully reimbursed for payments made or expenses
incurred in any fiscal year, it is entitled to carry forward these expenses to
subsequent fiscal years for submission to the applicable Fund for payment,
subject always to the maximum annual Class B distribution fee described above.

     The Board of Trustees of the Trust, on behalf of Intermediate Maturity
Fund, has determined that, if the Reorganization is consummated, unreimbursed
distribution and shareholder service expenses originally incurred in connection
with Intermediate Government Trust's shares will be reimbursable under
Intermediate Maturity Fund's Rule 12b-1 plans.  As of March 31, 1995, the
unreimbursed distribution and shareholder service expenses for Class A shares
and Class B shares of Intermediate Government Trust and Intermediate Maturity
Fund were $928 and $431 and $3,695 and $253,107, respectively.  See
"Unreimbursed Distribution and Shareholder Expenses" below.

PURCHASES AND EXCHANGES

   
     Shares of Intermediate Maturity Fund may be purchased through certain
broker-dealers and through John Hancock Funds at the public offering price,
which is based on the next determined net asset value per share, plus any
applicable sales charge.  The
    


                                      -11-
<PAGE>   18




   
minimum initial investment in Intermediate Maturity Fund is $1,000 ($250 for
group investments and retirement plans).  In anticipation of the Reorganization,
after the Record Date, no new accounts may be opened in Intermediate Government
Trust.  Existing shareholders of Intermediate Government Trust may continue to
purchase shares of the Fund after the Record Date.
    

     Shareholders of both Funds may exchange their shares at net asset value for
shares of the same class, if applicable, of certain other funds managed by the
Adviser.  Shares of any fund acquired in this manner that are subject to a CDSC
will incur the CDSC, if still applicable, upon redemption.  The exchange
privilege is available only in those states where exchanges can be made legally.

DISTRIBUTION PROCEDURES

     It is the policy of both Funds to declare dividends daily and to pay
dividends monthly from net investment income.  Each Fund also distributes
annually all of its other taxable income, including any net short-term and
long-term capital gains it has realized.  Intermediate Government Trust will
make, immediately prior to the Closing Date (as defined below), a distribution
of any net income and net realized capital gains it has not yet distributed.

REINVESTMENT OPTIONS

     Unless an election is made to receive cash, the shareholders of both Funds
automatically reinvest all of their respective dividends and capital gain
distributions in additional shares of the same class of the same Fund.  These
reinvestments are made at the net asset value per share and are not subject to
any sales charge.

REDEMPTION PROCEDURES

     Shares of both Funds may be redeemed on any day that the Fund is open for
business at a price equal to the net asset value of the shares next determined
after receipt of a redemption request in good order, less any applicable CDSC.
Alternatively, share- holders of both Funds may sell their shares through
securities dealers, who may charge a fee.  Redemptions and repurchases of Class
B shares and certain Class A shares of Intermediate Government Trust and
Intermediate Maturity Fund are subject to the applicable CDSC, if any.  Class A
and Class B shares of Intermediate Government Trust may be redeemed up to and
including the Closing Date (as defined below).

REORGANIZATION

     Effect of the Reorganization.  Pursuant to the terms of the Agreement, the
proposed Reorganization will consist of the acquisition by Intermediate Maturity
Fund of all the assets of Intermediate Government Trust in exchange solely for
(i) the assumption by Intermediate Maturity Fund of all the liabilities of
Intermediate Government Trust and (ii) the issuance of Intermediate Maturity
Fund shares equal to the value of these assets, less the amount of these
liabilities (the "Intermediate Maturity Fund Shares"), to Intermediate
Government Trust.  As part of the liquidation process, Intermediate Government
Trust will immediately distribute to its shareholders these Intermediate
Maturity Fund Shares in exchange for their shares of Intermediate Government
Trust.  Consequently, Class A shareholders of Intermediate Government Trust will
become Class A shareholders of Intermediate Maturity Fund and Class B
shareholders of Intermediate Government Trust will become Class B shareholders
of Intermediate Maturity Fund.  After completion of the Reorganization, the
existence of Intermediate Government Trust will be terminated.

     The Reorganization will become effective as of 5:00 p.m. on the closing
date, scheduled for September 22, 1995, or another date on or before December
31, 1995 as authorized representatives of the Funds may agree (the "Closing
Date").  The Intermediate Maturity Fund Class A Shares issued to Intermediate
Government Trust for distribution to Intermediate Government Trust's Class A
shareholders will have an aggregate net asset value equal to that of
Intermediate Government Trust's Class A shares.  The Intermediate Maturity Fund
Class B shares issued to Intermediate Government Trust for distribution to
Intermediate Government Trust's Class B shareholders will have an aggregate net
asset value equal to that of Intermediate Government Trust's Class B shares. For
purposes of the Reorganization, the Funds' respective asset values will be
determined as of the close of business (4:00 p.m. Eastern Time) on the Closing
Date.

   
     The Board of Trustees, including the Trustees not affiliated with the
Adviser, unanimously approved the Reorganization, and determined that it was in
the best interests of both Intermediate Government Trust and Intermediate
Maturity Fund and that the interests of Intermediate Government Trust's and
Intermediate Maturity Fund's shareholders would not be materially diluted as a
result of the Reorganization.  For a discussion of the factors considered by the
Board of Trustees, see "Proposal to Approve the Agreement and Plan of
Reorganization--Reasons for the Proposed Reorganization."
    

     Tax Considerations.  The consummation of the Reorganization is subject to
the receipt of an opinion of Hale and Dorr, counsel to the Funds, satisfactory
to the Trust, on behalf of each Fund,


                                      -13-
<PAGE>   20




as set forth in the Agreement and substantially to the effect that:

     (a)  The acquisition by Intermediate Maturity Fund of all of the assets of
Intermediate Government Trust solely in exchange for the issuance of
Intermediate Maturity Fund Shares to Intermediate Government Trust and the
assumption of all of Intermediate Government Trust's liabilities by Intermediate
Maturity Fund, followed by the distribution by Intermediate Government Trust, in
liquidation of Intermediate Government Trust, of Intermediate Maturity Fund
Shares to the shareholders of Intermediate Government Trust in exchange for
their shares of beneficial interest of Intermediate Government Trust and the
termination of Intermediate Government Trust, will constitute a "reorganization"

reorganization" within the meaning of Section 368(b) of the Code;

     (b)  no gain or loss will be recognized by Intermediate Government Trust

     (g)  the basis of the Intermediate Maturity Fund Shares received by

exchange therefor; and

     (h)  the tax holding period of the Intermediate Maturity Fund Shares
received by Intermediate Government Trust shareholders will include, for each

THE MEETING

     Time, Place and Date.  The Meeting will be held on Friday, September 8,
1995, at 101 Huntington Avenue, Boston, Massachusetts 02199, at 9:00 a.m.,
Boston time.

RECORD DATE

     The Record Date for determining shareholders entitled to notice of and to
vote at the Meeting is July 14, 1995.

VOTE REQUIRED

     Approval of the Agreement by the shareholders of Intermediate Government
Trust requires the affirmative vote of a majority of the shares of Intermediate
Government Trust represented in person or by proxy and entitled to vote at a
meeting of Shareholders at which a quorum is present.  The Reorganization does
not require the approval of Intermediate Maturity Fund's shareholders.  See
"Proposal to Approve the Agreement and Plan of Reorganization-- Voting Rights
and Required Vote."

                    RISK FACTORS AND SPECIAL CONSIDERATIONS

   
     The investment objectives of the Funds are identical and the investment
policies of the Funds are substantially similar.  For this reason, the risks
associated with an investment in the Funds are substantially similar.  These
include the risk that the value of U.S. Government securities will decline in
response to increases in interest rate levels.  The Funds' investments in
mortgage-backed securities are subject to the reinvestment risk associated with
early payments of principal and interest on the underlying mortgages.  In
addition, mortgage foreclosures and prepayments of principal may result in some
loss to the Funds' principal investment in mortgage-backed securities purchased
as a premium.  The Funds' investments in options, futures and other derivative
instruments may include the risk that the applicable market will move against a
Fund's derivative position and that the Fund will incur a loss.  Derivative
instruments may increase or leverage a Fund's exposure to a particular market
risk, which may
    


                                      -15-
<PAGE>   22




   
increase the volatility of the Fund's net asset value.  The Intermediate
Maturity Fund's success in using options and futures to hedge portfolio assets
depends on the degree of price correlation between the instrument and the hedged
asset.  Some investments in which a Fund may invest are not readily marketable
or may become illiquid under adverse market conditions. Intermediate Maturity
Fund is permitted to invest up to 15% of its assets in illiquid securities,
while Intermediate Government Trust may invest only 10% of its assets in these
securities. Intermediate Maturity Fund is authorized to invest up to one-third
of its total assets in reverse repurchase agreements and covered mortgage dollar
rolls, while Intermediate Government Trust may invest only 20% of its total
assets in such instruments.  The use of reverse repurchase agreements involves
leverage.  Leverage allows any investment gains made with the additional monies
received to increase the net asset value of the Funds' shares. However, if the
additional monies received are invested in ways that do not fully recover the
costs to a Fund of these transactions, the net asset value of that Fund may fall
faster than otherwise would have been the case.  Covered mortgage dollar rolls
are not treated as a borrowing.
    

                       INFORMATION CONCERNING THE MEETING

SOLICITATION, REVOCATION AND USE OF PROXIES

     A majority of Intermediate Government Trust's outstanding shares that are
represented and entitled to vote at the Meeting will be a quorum for the
transaction of business.  An Intermediate Government Trust shareholder executing
and returning a proxy has the power to revoke it at any time before it is
exercised, by filing a written notice of revocation with Intermediate Government
Trust's transfer agent, Investor Services, P.O. Box 9116, Boston, Massachusetts
02205-9116, or by returning a duly executed proxy with a later date before the
time of the Meeting.  Any shareholder who has executed a proxy but is present at
the Meeting and wishes to vote in person may revoke his or her proxy by
notifying the Secretary of Intermediate Government Trust (without complying with
any formalities) at any time before it is voted.  Presence at the Meeting alone
will not serve to revoke a previously executed and returned proxy.

     If a quorum is not present in person or by proxy at the time any session of
the Meeting is called to order, the persons named as proxies may vote those
proxies that have been received to adjourn the Meeting to a later date.  If a
quorum is present but there are not sufficient votes in favor of the Proposal,
the persons named as proxies may propose one or more adjournments of the Meeting
to permit further solicitation of proxies with respect to the Proposal.  Any
adjournment will require the affirmative vote of a majority of the shares of
Intermediate Government Trust, represented in person or by proxy, at the session
of the Meeting


                                      -16-
<PAGE>   23




to be adjourned.  If an adjournment of the Meeting is proposed because there are
not sufficient votes in favor of the Reorganization, the persons named as
proxies will vote those proxies in favor of the Reorganization in favor of
adjournment, and will vote those proxies against the Reorganization against
adjournment.

   
     In addition to the solicitation of proxies by mail or in person,
Intermediate Government Trust may also arrange to have votes recorded by
telephone by officers and employees of the Fund or by personnel of the Adviser
or Investor Services.  The telephone voting procedure is designed to
authenticate a shareholder's identity, to allow a shareholder to authorize the
voting of shares in accordance with the shareholder's instructions and to
confirm that the voting instructions have been properly recorded.  If these
procedures were subject to a successful legal challenge, such votes would not be
counted at the Meeting.  The Fund has not sought to obtain an opinion of counsel
on this matter and is unaware of any such challenge at this time.  A shareholder
would be called on a recorded line at the telephone number the Fund has in its
records for the account and would be asked the shareholder's Social Security
number of other identifying information.  The shareholder would then be given an
opportunity to authorize proxies to vote his shares at the Meeting in accordance
with the shareholder's instructions.  To ensure that the shareholder's
instructions have been recorded correctly, the shareholder will also receive a
confirmation of the voting instructions in the mail.  A special toll-free number
will be available in case the voting information contained in the confirmation
is incorrect.  If the shareholder decides after voting by telephone to attend
the Meeting, the shareholder can revoke the proxy at that time and vote the
shares at the Meeting.
    

OUTSTANDING SHARES AND RECORD DATE

   
     At the close of business on June 30, 1995, 787,138 Class A shares and
47,484 Class B shares of beneficial interest of Intermediate Government Trust
were outstanding and entitled to vote.  Only Intermediate Government Trust
shareholders of record at the close of business on July 14, 1995 (the "Record
Date") are entitled to notice of and to vote at the Meeting and any adjournment
of the Meeting.  As of June 30, 1995, 1,817,177 Class A and 938,578 Class B
shares of beneficial interest of Intermediate Maturity Fund were outstanding.

                       PROPOSAL TO APPROVE THE AGREEMENT
                           AND PLAN OF REORGANIZATION

GENERAL

     The shareholders of Intermediate Government Trust are being asked to
approve the Agreement, a copy which is attached as EXHIBIT A.  The
Reorganization will consist of:  (a) the transfer of all of Intermediate
Government Trust's assets to Intermediate Maturity Fund, in exchange solely for
the issuance of Intermediate Maturity Fund Shares to Intermediate Government
Trust and the assumption of Intermediate Government Trust's liabilities by
Intermediate Maturity Fund, (b) the subsequent distribution by Intermediate
Government Trust, as part of its liquidation, of the Intermediate Maturity Fund
Shares to Intermediate Government Trust's shareholders and (c) the termination
of Intermediate


                                      -18-
<PAGE>   25




Government Trust's existence.  The Intermediate Maturity Fund Class A Shares
issued upon the consummation of the Reorganization will have an aggregate net
asset value equal to that of Intermediate Government Trust's Class A shares. The
Intermediate Maturity Fund Class B Shares issued upon consummation of the
Reorganization will have an aggregate net asset value equal to that of
Intermediate Government Trust's Class B shares.  As noted above, the asset
values of Intermediate Government Trust and Intermediate Maturity Fund will be
determined at the close of business (4:00 p.m. Eastern Time) on the Closing Date
for purposes of the Reorganization.  See "Description of Agreement" below.

     Pursuant to the Agreement, Intermediate Government Trust will liquidate and
distribute the Intermediate Maturity Fund Shares received, as described above,
pro rata to the shareholders of record of each class determined as of the close
of regular trading on the New York Stock Exchange on the Closing Date.  The
result of the transfer of assets will be that Intermediate Maturity Fund will
add to its portfolio the net assets of Intermediate Government Trust.  Class A
shareholders of Intermediate Government Trust will become Class A shareholders
of Intermediate Maturity Fund, and Class B shareholders of Intermediate
Government Trust will become Class B shareholders of Intermediate Maturity Fund.

     The Agreement and the Reorganization were unanimously approved by the Board
of Trustees of the Trust on behalf of each of Intermediate Government Trust and
Intermediate Maturity Fund at a meeting held on May 16, 1995.

     The Trust's Board of Trustees has also approved the reorganization of
another series of the Trust, John Hancock U.S. Government Trust, into
Intermediate Maturity Fund (the "U.S. Government Reorganization").  On March 31,
1995, U.S. Government Trust had net assets of $17,780,907.  The Reorganization
of Intermediate Government Trust described in this Proxy Statement and
Prospectus is not contingent in any way upon the consummation of the U.S.
Government Reorganization.  The U.S. Government Reorganization will not affect
the net asset value of the Intermediate Maturity Fund Shares or the number of
such Shares to be received by the shareholders of Intermediate Government Trust.

REASONS FOR THE PROPOSED REORGANIZATION

     The Board of Trustees believes that the proposed Reorganization will be
advantageous to the shareholders of Intermediate Government Trust in several
respects.  The Board of Trustees considered the following matters, among others,
in approving the Proposal.

   
     First, the Board of Trustees believes that it is not advantageous to
operate and market Intermediate Government Trust separately from Intermediate
Maturity Fund, because the investment
    


                                      -19-
<PAGE>   26




objectives of the two Funds are similar and their investment policies are
substantially similar.

   
     Second, the Board of Trustees considered the fact that Intermediate
Government Trust is significantly smaller than Intermediate Maturity Fund.  The
Board of Trustees determined that the existence of a larger competing fund
within the same fund complex and with substantially similar investment
characteristics is likely to impede the marketing and asset growth of
Intermediate Government Trust.
    

     Third, the Board of Trustees considered that shareholders of both Funds may
be better served by a fund offering greater diversification.  To the extent that
the Funds' assets are combined into a single portfolio and a larger asset base
is created as a result of the Reorganization, greater diversification of
Intermediate Maturity Fund's investment portfolio can be achieved than is
currently possible in either Fund.  Greater diversification is expected to be
beneficial to shareholders of both Funds, because it may reduce the negative
effect which the adverse performance of any one security may have on the
performance of the entire portfolio.

     Fourth, the Board of Trustees believes that the Intermediate Maturity Fund
Shares received in the Reorganization will provide existing Intermediate
Government Trust shareholders with substantially the same investment advantages
that they currently enjoy at a comparable level of risk.  The Board of Trustees
also considered the performance history of each Fund.

     Fifth, a combined fund offers economies of scale that should have a
positive effect on the expenses currently borne by Intermediate Government Trust
and directly and indirectly by Intermediate Maturity Fund.  Both Funds incur
substantial overhead costs for accounting, legal, transfer agency services,
insurance, and custodial and administrative services.  The Board of Trustees
expects that the Reorganization will result in a decrease in the expenses
currently borne by Intermediate Government Trust's shareholders.  See
"Summary--The Funds' Expenses."

     In determining that the Reorganization is in the best interests of
Intermediate Government Trust and its shareholders, the Board of Trustees
considered the fact that the Adviser will receive certain benefits from the
Reorganization.  The Reorganization will result in a consolidated portfolio
management effort, and may result in time savings to the Adviser by reducing the
number of reports and regulatory filings that its personnel must prepare.





                                      -20-

CAPITAL LOSS CARRYOVERS

     As of March 31, 1995, Intermediate Government Trust had capital loss
carryovers, as determined for federal income tax purposes, in the aggregate
amount of approximately $735,389, of which $28,597 expires on December 31, 1997,
and $706,792 expires on December 31, 2002.  If the Reorganization does not
occur, Intermediate Government Trust may use these capital loss carryovers to
offset its net capital gain, which would reduce the amount of net capital gain
Intermediate Government Trust would be required to distribute to its
shareholders in order to avoid fund- level income and/or excise taxes on
undistributed capital gain.

     If the Reorganization is consummated, Intermediate Maturity Fund will
succeed to and take into account Intermediate Government Trust's capital loss
carryovers and will be able to use such carryovers, along with any carryovers it
may have, to offset its net capital gain, subject to certain limitations under
the Code that may be applicable because of the Reorganization and certain other
changes in the past or future share ownership of Intermediate Maturity Fund,
including the issuance of shares of Intermediate Maturity Fund in other
reorganization transactions. These limitations could result in the expiration of
all or portions of such carryovers before they are fully used.  However,
Intermediate Government Trust did not, as of March 31, 1995, have net unrealized
gains that, when realized, its capital loss carryovers could be used to offset,
and accordingly all or substantial portions of Intermediate Government Trust's
capital loss carryovers may also expire unused if the Reorganization is not
consummated.

UNREIMBURSED DISTRIBUTION AND SHAREHOLDER SERVICE EXPENSES

     The Board of Trustees has determined that, if the Reorganization is
consummated, distribution and shareholder service expenses incurred in
connection with shares of Intermediate Government Trust, and not reimbursed
under Intermediate Government Trust's Rule 12b-1 Plans or through CDSCs, will be
reimbursable expenses under Intermediate Maturity Fund's Rule 12b-1 Plans (the
"assumption").  However, the maximum aggregate amounts payable during any fiscal
year under Intermediate Maturity Fund's Rule 12b-1 Plan (0.25% of average daily
net assets attributable to Class A shares and 1.00% of average daily net assets
attributable to Class B shares) will not be affected by the assumption.

     With respect to both Class A and Class B shares of Intermediate Maturity
Fund, the percentage of net assets on a pro forma combined basis that the
unreimbursed expenses represent will decrease as a result of the Reorganization
and the assumption.  As of March 31, 1995, the unreimbursed distribution and
shareholder service expenses of Intermediate Maturity Fund attributable to


                                      -21-
<PAGE>   28




Class A and Class B shares were $3,695 (0.029% of Intermediate Maturity Fund's
net assets attributable to Class A shares) and $253,107 (2.664% of Intermediate
Maturity Fund's net assets attributable to Class B shares), respectively.  As of
the same date, the unreimbursed distribution and shareholder service expenses of
Intermediate Government Trust attributable to Class A and Class B shares were
$928 (0.012% of Intermediate Government Trust's net assets attributable to Class
A shares) and $431 (0.146% of Intermediate Government Trust's net assets
attributable to Class B shares), respectively.

     After the Reorganization, on a pro forma combined basis, the unreimbursed
distribution and shareholder service expenses of Intermediate Maturity Fund
attributable to Class A and Class B shares will be $4,623 (0.022% of
Intermediate Maturity Fund's pro forma net assets attributable to Class A
shares) and $253,538 (2.589% of Intermediate Maturity Fund's pro forma net
assets attributable to Class B shares), respectively.

     The assumption will have no immediate effect upon the payments made under
Intermediate Maturity Fund's Rule 12b-1 Plans. While John Hancock Funds hopes to
recover unreimbursed distribution and shareholder service expenses over an
extended period of time, Intermediate Maturity Fund is not obligated to assure
that these amounts are recouped by John Hancock Funds. Unreimbursed distribution
and shareholder service expenses do not currently appear as an expense or
liability in the financial statements of either Fund, nor will they appear in
the financial statements of Intermediate Maturity Fund after the Reorganization
until paid or accrued.  Unreimbursed expenses do not enter into the calculation
of the Fund's net asset value or the formula for calculating Rule 12b-1
payments.  Even in the event of termination or noncontinuance of Intermediate
Maturity Fund's 12b-1 Plans, Intermediate Maturity Fund is not legally
committed, and is not required to commit, to the payment of any unreimbursed
distribution and shareholder service expenses.  The staff of the Securities and
Exchange Commission has not approved or disapproved the treatment of the
unreimbursed distribution and shareholder service expenses described in this
Proxy Statement.

BOARDS' EVALUATION AND RECOMMENDATION

   
     On the basis of the factors described above and other factors, the Board of
Trustees, including a majority of the Trustees who are not "interested persons"
(as defined in the Investment Company Act) of the Funds, determined that the
Reorganization is in the best interests of Intermediate Government Trust and
that the interests of Intermediate Government Trust's shareholders will not be
materially diluted as a result of the Reorganization.  On the same basis, the
Board of Trustees of the Trust, including a majority of the Trustees who are not
"interested persons" (as defined in the Investment Company Act) of
    


                                      -22-
<PAGE>   29



the Funds, determined that the Reorganization is in the best interests of
Intermediate Maturity Fund and the interests of Intermediate Maturity Fund's
shareholders will not be materially diluted as a result of the Reorganization.

     THE TRUSTEES OF JOHN HANCOCK INTERMEDIATE GOVERNMENT TRUST RECOMMEND THAT
THE SHAREHOLDERS OF JOHN HANCOCK INTERMEDIATE GOVERNMENT TRUST VOTE FOR THE
PROPOSAL TO APPROVE THE AGREEMENT AND PLAN OF REORGANIZATION.

DESCRIPTION OF AGREEMENT

     The following description of the Agreement is a summary, does not purport
to be complete, and is subject in all respects to the provisions of the
Agreement, and is qualified in its entirety by reference to the Agreement.  A
copy of the Agreement is attached to this Proxy Statement and Prospectus as
EXHIBIT A and should be read in its entirety.  Paragraph references are to
appropriate provisions of the Agreement.

     Method of Carrying Out Reorganization.  If Intermediate Government Trust
shareholders approve the Agreement, the Reorganization will be consummated
promptly after the various conditions to the obligations of each of the parties
are satisfied (see Agreement, paragraphs 6 through 8).  The Reorganization will
be completed on the Closing Date (as defined above).

     On the Closing Date, Intermediate Government Trust will transfer all of its
assets to Intermediate Maturity Fund in exchange for Intermediate Maturity Fund
Shares with an aggregate net asset value equal to the value of the assets
delivered, less the liabilities of Intermediate Government Trust assumed, as of
the close of business on the Closing Date (see Agreement, paragraphs 1 and 2).

     The value of Intermediate Government Trust's assets and Intermediate
Maturity Fund's net asset values per Class A share and per Class B share will be
determined according to the valuation procedures set forth in the Trust's
Declaration of Trust and By-laws and the Intermediate Maturity Fund Preliminary
Prospectus, respectively (see "Share Price" in the Intermediate Maturity Fund
Preliminary Prospectus).  No initial sales charge or CDSC will be imposed upon
delivery of the Intermediate Maturity Fund Shares in exchange for the assets of
Intermediate Government Trust.

     Surrender of Share Certificates.  Intermediate Government Trust
shareholders whose Class A or Class B shares are represented by one or more
share certificates should, prior to the Closing Date, either surrender their
certificates to Intermediate Government Trust or deliver to Intermediate
Government Trust an affidavit with respect to lost certificates, in the form and


                                      -23-
<PAGE>   30




accompanied by the surety bonds that Intermediate Government Trust may require
(collectively, an "Affidavit").  On the Closing Date, all certificates which
have not been surrendered will be deemed to be cancelled, will no longer
evidence ownership of Intermediate Government Trust's shares and will evidence
ownership of Intermediate Maturity Fund Shares.  Shareholders may not redeem or
transfer Intermediate Maturity Fund Shares received in the Reorganization until
they have surrendered their Intermediate Government Trust share certificates or
delivered an Affidavit relating to them.  Intermediate Maturity Fund will not
issue share certificates in the Reorganization.

     Conditions Precedent to Closing.  The obligation of Intermediate Government
Trust to consummate the Reorganization is subject to the satisfaction of certain
conditions precedent, including the Trust's performance of all acts and
undertakings required under the Agreement and the receipt of all consents,
orders and permits necessary to consummate the Reorganization (see Agreement,
paragraphs 6 through 8).

     The obligation of Intermediate Maturity Fund to consummate the
Reorganization is subject to the satisfaction of certain conditions precedent,
including the Trust's performance of all acts and undertakings to be performed
under the Agreement, the receipt of certain documents and financial statements
from the Trust, on behalf of Intermediate Government Trust, and the receipt of
all consents, orders and permits necessary to consummate the Reorganization (see
Agreement, paragraphs 6 through 8).

     The obligations of both parties are subject to the receipt of approval and
authorization of the Agreement by the vote of not less than a majority of the
outstanding shares of beneficial interest of Intermediate Government Trust
entitled to vote (as described in the section captioned "Voting Rights and
Required Vote"), the receipt of a favorable opinion of Hale and Dorr as to the
federal income tax consequences of the Reorganization and the approval by
shareholders of Adjustable Government Trust of the proposals to change the
structure of that Fund and its investment objective and an investment
restriction (see Agreement, paragraph 8).

     Termination of Agreement.  The Agreement may be terminated, whether or not
approval of Intermediate Government Trust's shareholders has been obtained, by
mutual agreement of the parties.  In addition, either party may terminate its
obligations under the Agreement at or prior to the Closing Date, because of a
material breach by the other party of any representations, warranties or
agreements contained in the Agreement, or if a condition precedent in the
Agreement has not been met.

     Expenses of the Reorganization.  Intermediate Maturity Fund and
Intermediate Government Trust will each be responsible for its


                                      -24-
<PAGE>   31




own expenses incurred in connection with entering into and carrying out the
provisions of the Agreement, whether or not the Reorganization is consummated.

     Tax Considerations.  The consummation of the Reorganization is subject to
the receipt of a favorable opinion of Hale and Dorr, counsel to the Funds,
satisfactory to the Trust on behalf of each of Intermediate Government Trust and
Intermediate Maturity Fund and described above under the caption
"Summary--Reorganization-Tax Considerations."

VOTING RIGHTS AND REQUIRED VOTE

     Each Intermediate Government Trust share is entitled to one vote.  Class A
and Class B shareholders of Intermediate Government Trust vote together with
respect to the Proposal.  Approval of the Proposal requires the affirmative vote
of a majority of the shares of Intermediate Government Trust, represented in
person or by proxy and entitled to vote at a meeting of shareholders at which a
quorum is present.

     Shares of beneficial interest of Intermediate Government Trust represented
in person or by proxy, including shares which abstain or do not vote with
respect to the Proposal, will be counted for purposes of determining whether a
quorum is present at the Meeting.  Accordingly, an abstention from voting has
the same effect as a vote against the Proposal.  However, if a broker or nominee
holding shares in "street name" indicates on the proxy card that it does not
have discretionary authority to vote on the Proposal, those shares will not be
considered as present and entitled to vote with respect to the Proposal.
Accordingly, a "broker non-vote" has no effect on the voting in determining
whether the Proposal has been adopted, provided that the holders of more than
50% of the outstanding shares (excluding the "broker non-votes") are present or
represented.

     If the requisite approval of shareholders is not obtained, Intermediate
Government Trust will continue to engage in business as a registered open-end,
management investment company and the Board of Trustees will consider what
further action may be appropriate.

                                 CAPITALIZATION

     The following table sets forth the capitalization of each Fund as of March
31, 1995, and the pro forma combined capitalization of both Funds as if the
Reorganization had occurred on that date.  The table reflects pro forma exchange
ratios of approximately 0.94914 Class A Intermediate Maturity Fund Shares being
issued for each Class A share of Intermediate Government Trust, and

Government Trust.  If the Reorganization is consummated, the actual exchange
ratios on the Closing Date may vary from those indicated due to (i) changes in
the market value of the portfolio securities of both Intermediate Maturity Fund
and Intermediate Government Trust between March 31, 1995 and the Closing Date,
(ii) changes in the amount of undistributed net investment income and net
realized capital gains of Intermediate Maturity Fund and Intermediate Government
Trust during that period resulting from income and distributions, and (iii)
changes in the accrued liabilities of Intermediate Maturity Fund and
Intermediate Government Trust during the same period.

(1)  Adjusted to reflect the proposed abolition of the master/feeder structure;
     without such adjustment, the net assets would be $22,455,416 and the net
     asset value of a Class A and Class B share would be $9.79, respectively.
    

(2)  If the Reorganization had taken place on March 31, 1995, Intermediate
     Government Trust would have received 819,048 Class A shares and 30,168
     Class B shares of Intermediate Maturity Fund, which would have been
     available for distribution to shareholders of the applicable class of
     Intermediate Government Trust.  No assurance can be given as to the number
     of Class A Shares or Class B shares of Intermediate Maturity Fund that will
     be received by Intermediate Government Trust on the Closing Date.  The
     foregoing is merely an example of what Intermediate Government Trust would
     have received and distributed had the Reorganization been consummated on
     March 31, 1995, and should

     the Closing Date.

(3)  If both the Reorganization and the U.S. Government Reorganization had taken
     place on March 31, 1995, Intermediate Maturity Fund's pro forma combined
     net assets would be $48,530,602 and the number of Class A and Class B
     Intermediate Maturity Fund Shares outstanding would have been 3,940,150 and
     1,021,937, respectively.  The U.S. Government Reorganization will not
     affect the net asset value of the Class A or Class B Intermediate Maturity
     Fund Shares to be issued in the Reorganization.

     The average annual total return of each class of the Funds is determined by
multiplying a hypothetical initial investment of $1,000 in a class by the
average annual compound rate of return (including capital
appreciation/depreciation, and dividends and distributions paid and reinvested)
attributable to that class for the stated period and annualizing the result.

     The table below indicates the total return (capital changes plus
reinvestment of all dividends and distributions) on a hypothetical investment of
$1,000 in each class of each Fund covering the indicated periods ending March
31, 1995.  The data below represent historical performance which should not be
considered indicative of future performance of either Fund.  Each Fund's
performance and net asset value will fluctuate so that their shares, when
redeemed, may be worth more or less than their original cost.

                                  EXHIBIT A


                      AGREEMENT AND PLAN OF REORGANIZATION


   
     THIS AGREEMENT AND PLAN OF REORGANIZATION (the "Agreement") is made this
14th day of July, 1995, by and between John Hancock Adjustable U.S. Government
Trust (as proposed to be renamed, John Hancock Intermediate Maturity Government
Fund) (the "Acquiring Fund") and John Hancock Intermediate Government Trust (the
"Acquired Fund"), each a series of John Hancock Bond Fund (the "Trust"), a
Massachusetts business trust with its principal place of business at 101
Huntington Avenue, Boston, Massachusetts 02199. The Acquiring Fund and the
Acquired Fund are sometimes referred to collectively herein as the "Funds" and
individually as a "Fund."
    

     This Agreement is intended to be and is adopted as a plan of
"reorganization," as such term is used in Section 368(a) of the Internal Revenue
Code of 1986, as amended (the "Code").  The reorganization will consist of the
transfer of all of the assets of the Acquired Fund to the Acquiring Fund in
exchange solely for the issuance of Class A and Class B shares of beneficial
interest of the Acquiring Fund (the "Acquiring Fund Shares") to the Acquired
Fund and the assumption by the Acquiring Fund of all of the liabilities of the
Acquired Fund, followed by the distribution by the Acquired Fund, on or promptly
after the Closing Date hereinafter referred to, of the Acquiring Fund Shares to
the shareholders of the Acquired Fund in liquidation and termination of the
Acquired Fund as provided herein, all upon the terms and conditions set forth in
this Agreement.

     In consideration of the premises of the covenants and agreements
hereinafter set forth, the parties hereto covenant and agree as follows:


1.   TRANSFER OF ASSETS OF THE ACQUIRED FUND IN EXCHANGE FOR ASSUMPTION OF
     LIABILITIES AND ISSUANCE OF ACQUIRING FUND SHARES; LIQUIDATION OF THE
     ACQUIRED FUND

     1.1  The Acquired Fund will transfer all of its assets (consisting, without
limitation, of portfolio securities and instruments, dividends and interest
receivables, cash and other assets), as set forth in the statement of assets and
liabilities referred to in Paragraph 7.2 hereof (the "Statement of Assets and
Liabilities"), to the Acquiring Fund free and clear of all liens and
encumbrances, except as otherwise provided herein, in exchange for (i) the
assumption by the Acquiring Fund of the known and unknown liabilities of the
Acquired Fund, including the liabilities set forth in the Statement of Assets
and Liabilities (the "Acquired Fund Liabilities"), which shall be assigned and
transferred to the Acquiring Fund by the Acquired Fund and assumed by the
Acquiring Fund, and (ii) delivery by the Acquiring Fund to the Acquired Fund,
for distribution pro rata by the Acquired Fund


                                     A-1

<PAGE>   40




to its Class A and Class B shareholders in proportion to their respective
ownership of Class A and/or Class B shares of beneficial interest of the
Acquired Fund, as of the close of business on the closing date (the "Closing
Date"), of a number of the Acquiring Fund Shares having an aggregate net asset
value, in the case of each class of Acquiring Fund Shares, equal to the value of
the assets, less such liabilities (herein referred to as the "net value of the
assets"), attributable to the corresponding class of the Acquired Fund so
transferred, assumed, assigned and delivered, all determined as provided in
Paragraph 2.1 hereof and as of a date and time as specified therein.  Such
transactions shall take place at the closing provided for in Paragraph 3.1
hereof (the "Closing").  All computations shall be provided by Investors Bank &
Trust Company (the "Custodian"), as custodian and pricing agent for the
Acquiring Fund and the Acquired Fund, and shall be recomputed by Ernst & Young
LLP, the independent accountants of the Acquiring Fund.  The determination of
the Custodian, as recomputed by said accountants, shall, absent manifest error,
be conclusive and binding on all parties in interest.

     1.2  The Acquired Fund has provided the Acquiring Fund with a list of the
current securities holdings of the Acquired Fund as of the date of execution of
this Agreement.  The Acquired Fund reserves the right to sell any of these
securities (except to the extent sales may be limited by representations made in
connection with issuance of the tax opinion provided for in paragraph 8.6
hereof) but will not, without the prior approval of the Acquiring Fund, acquire
any additional securities other than securities of the type in which the
Acquiring Fund is permitted to invest.

     1.3  The Acquiring Fund and the Acquired Fund shall each bear its own
expenses in connection with the transactions contemplated by this Agreement.

     1.4  On or as soon after the Closing Date as is conveniently practicable
(the "Liquidation Date"), the Acquired Fund will liquidate and distribute pro
rata to shareholders of record of the applicable class (the "Acquired Fund
shareholders"), determined as of the close of regular trading on the New York
Stock Exchange on the Closing Date, the Acquiring Fund Shares received by the
Acquired Fund pursuant to Paragraph 1.1 hereof.  Such liquidation and
distribution will be accomplished by the transfer of the Acquiring Fund Shares
then credited to the account of the Acquired Fund on the books of the Acquiring
Fund, to open accounts on the share records of the Acquiring Fund in the names
of the Acquired Fund shareholders and representing the respective pro rata
number and class of Acquiring Fund Shares due such shareholders. Acquired Fund
shareholders who own Class A shares of the Acquired Fund will receive Class A
Acquiring Fund Shares, and Acquired Fund shareholders who own Class B shares of
the Acquired Fund will receive Class B Acquiring Fund Shares.  The Acquiring
Fund shall


                                     A-2

<PAGE>   41




not issue certificates representing Acquiring Fund Shares in connection with
such exchange.

     1.5  The Acquired Fund shareholders holding certificates representing their
ownership of shares of beneficial interest of the Acquired Fund shall surrender
such certificates or deliver an affidavit with respect to lost certificates in
such form and accompanied by such surety bonds as the Acquired Fund may require
(collectively, an "Affidavit"), to John Hancock Investor Services Corporation
prior to the Closing Date.  Any Acquired Fund share certificate which remains
outstanding on the Closing Date shall be deemed to be cancelled, shall no longer
evidence ownership of shares of beneficial interest of the Acquired Fund and
shall evidence ownership of Acquiring Fund Shares.  Unless and until any such
certificate shall be so surrendered or an Affidavit relating thereto shall be
delivered, dividends and other distributions payable by the Acquiring Fund
subsequent to the Liquidation Date with respect to Acquiring Fund Shares shall
be paid to the holder of such certificate(s), but such shareholders may not
redeem or transfer Acquiring Fund Shares received in the Reorganization. The
Acquiring Fund will not issue share certificates in the Reorganization.

2.   VALUATION

     2.1  The net asset values of the Class A and Class B Acquiring Fund Shares
and the net values of the assets and liabilities of the Acquired Fund
attributable to its Class A and Class B shares to be transferred or assumed
shall, in each case, be determined as of the close of business (4:00 p.m. Boston
time) on the Closing Date.  The net asset values of the Class A and Class B
Acquiring Fund Shares shall be computed by the Custodian in the manner set forth
in the Trust's Declaration of Trust, as


                                     A-3
<PAGE>   42




amended, or By-laws and the Acquiring Fund's then-current prospectus and
statement of additional information and shall be computed in each case to not
fewer than four decimal places.  The net values of the assets of the Acquired
Fund attributable to its Class A and Class B shares to be transferred shall be
computed by the Custodian by calculating the value of the assets of each class
transferred by the Acquired Fund and by subtracting therefrom the amount of the
liabilities of each respective class assigned and transferred to and assumed by
the Acquiring Fund on the Closing Date, said assets and liabilities to be valued
in the manner set forth in the Acquired Fund's then-current prospectus and
statement of additional information and shall be computed in each case to not
fewer than four decimal places.

     2.2  The number of shares of each class of Acquiring Fund Shares to be
issued (including fractional shares, if any) in exchange for the Acquired Fund's
assets shall be determined by dividing the value of the Acquired Fund's assets
attributable to a class, less the liabilities attributable to that class assumed
by the Acquiring Fund, by the Acquiring Fund's net asset value per share of the
same class, all as determined in accordance with Paragraph 2.1 hereof.

     2.3  All computations of value shall be made by the Custodian in accordance
with its regular practice as pricing agent for the Funds.


3.   CLOSING AND CLOSING DATE

     3.1  The Closing Date shall be September 22, 1995 or such other date on or
before December 31, 1995, as the parties may agree.  The Closing shall be held
as of 5:00 p.m. at the offices of the Trust, 101 Huntington Avenue, Boston,
Massachusetts 02199, or at such other time and/or place as the parties may

     3.2  Portfolio securities that are not held in book-entry form in the name
of the Custodian as record holder for the Acquired Fund shall be presented by
the Acquired Fund to the Custodian for examination no later than five business
days preceding the Closing Date.  Portfolio securities which are not held in

account of the Acquiring Fund on the Closing Date, duly endorsed in proper form
for transfer, in such condition as to constitute good delivery thereof in
accordance with the custom of brokers, and shall be accompanied by all necessary
federal and state stock transfer stamps or a check for the appropriate purchase
price thereof.  Portfolio securities held of record by the Custodian in

ownership

<PAGE>   43




thereof on its records.  The cash delivered shall be in the form of currency or
by the Custodian crediting the Acquiring Fund's account maintained with the
Custodian with immediately available funds.

     3.3  In the event that on the Closing Date (a) the New York Stock Exchange
shall be closed to trading or trading thereon shall be restricted or (b) trading
or the reporting of trading on said Exchange or elsewhere shall be disrupted so
that accurate appraisal of the value of the net assets of the Acquiring Fund or
the Acquired Fund is impracticable, the Closing Date shall be postponed until
the first business day after the day when trading shall have been fully resumed
and reporting shall have been restored; provided that if trading shall not be
fully resumed and reporting restored on or before December 31, 1995, this
Agreement may be terminated by the Acquiring Fund or by the Acquired Fund upon
the giving of written notice to the other party.

     3.4  The Acquired Fund shall deliver at the Closing a list of the names,

Date, or provide evidence satisfactory to the Acquired Fund that such Acquiring
Fund Shares have been credited to the Acquired Fund's account on the books of

     8.8  The parties shall have received an opinion of Messrs. Hale and Dorr,
satisfactory to the Trust on behalf of the Acquired Fund and the Trust on behalf
of the Acquiring Fund, substantially to the effect that for federal income tax
purposes:

          (a)  The acquisition by the Acquiring Fund of all of the assets of the
     Acquired Fund solely in exchange for the issuance of Acquiring Fund Shares
     to the Acquired Fund and the assumption of all of the Acquired Fund
     Liabilities by the Acquiring Fund, followed by the distribution by the
     Acquired Fund, in liquidation of the Acquired Fund, of Acquiring Fund
     Shares to the shareholders of the Acquired Fund in exchange for their
     shares of beneficial interest of the Acquired Fund and the termination of
     the Acquired Fund, will constitute a "reorganization" within the meaning of
     Section 368(a)(1)(c) of the Code, and the Acquired Fund and the Acquiring
     Fund will each be "a party to a reorganization" within the meaning of
     Section 368(b) of the Code;

          (b)  No gain or loss will be recognized by the Acquired Fund upon (i)
     the transfer of all of its assets to the Acquiring Fund solely in exchange
     for the issuance of Acquiring Fund Shares to the Acquired Fund and the
     assumption of all of the Acquired Fund Liabilities by the Acquiring Fund;
     and (ii) the distribution by the Acquired Fund of such Acquiring Fund
     Shares to the shareholders of the Acquired Fund;

          (c)  No gain or loss will be recognized by the Acquiring Fund upon the
     receipt of the assets of the Acquired Fund solely in exchange for the
     issuance of the Acquiring Fund Shares to the Acquired Fund and the
     assumption of all of the Acquired Fund Liabilities by the Acquiring Fund;

          (d)  The basis of the assets of the Acquired Fund acquired by the
     Acquiring Fund will be, in each instance, the same as the basis of those
     assets in the hands of the Acquired Fund immediately prior to the transfer;

          (e)  The tax holding period of the assets of the Acquired Fund in the
     hands of the Acquiring Fund will, in each instance, include the Acquired
     Fund's tax holding period for those assets;

          (f)  The shareholders of the Acquired Fund will not recognize gain or
     loss upon the exchange of all of their shares of the Acquired Fund solely
     for Acquiring Fund Shares as part of the transaction;





                                     A-16

<PAGE>   55




          (g)  The basis of the Acquiring Fund Shares received by the Acquired
     Fund shareholders in the transaction will be the same as the basis of the
     shares of beneficial interest of the Acquired Fund surrendered in exchange
     therefor; and

          (h)  The tax holding period of the Acquiring Fund Shares received by
     the Acquired Fund shareholders will include, for each shareholder, the tax
     holding period for the shares of the Acquired Fund surrendered in exchange
     therefor, provided that the Acquired Fund shares were held as capital
     assets on the date of the exchange.

     The Trust, on behalf of each of the Acquiring Fund and the Acquired Fund,
agrees to make and provide representations with respect to the Acquiring Fund
and the Acquired Fund, respectively, which are reasonably necessary to enable
Hale and Dorr to deliver an opinion substantially as set forth in this Paragraph
8.8. Notwithstanding anything herein to the contrary, the Trust may not waive
the conditions set forth in this Paragraph 8.8.


9.   BROKERAGE FEES AND EXPENSES

     9.1  The Trust, on behalf of the Acquiring Fund and the Acquired Fund,
represents and warrants to the Acquired Fund and the Acquiring Fund,
respectively, that there are no brokers or finders entitled to receive any
payments in connection with the transactions provided for herein.

for its own expenses incurred in connection with entering into and carrying out
the provisions of this Agreement whether or not the transactions contemplated
hereby are consummated.


10.  ENTIRE AGREEMENT; SURVIVAL OF WARRANTIES

     10.1  The Trust, on behalf of each of the Acquiring Fund and the Acquired
Fund, agrees that neither party has made any representation, warranty or
covenant not set forth herein or referred to in Paragraph 4 hereof and that this

11.  TERMINATION

     11.1  This Agreement may be terminated by the mutual agreement of the
Trust, on behalf of the Acquiring Fund, and the Trust, on behalf of the Acquired
Fund.  In addition, either party may at its option terminate this Agreement at
or prior to the Closing Date:

          (a)  because of a material breach by the other of any representation,
     warranty, covenant or agreement contained herein to be performed at or
     prior to the Closing Date;

          (b)  because of a condition herein expressed to be precedent to the
     obligations of the terminating party which has not been met and which
     reasonably appears will not or cannot be met; or

          (c)  by resolution of the Trust's Board of Trustees if circumstances
     should develop that, in the good faith opinion of such Board, make
     proceeding with the Agreement not in the best interest of either party's
     shareholders.

     11.2  In the event of any such termination, there shall be no liability for
damages on the part of the Trust, the Acquiring Fund or the Acquired Fund, or
the Directors or officers of the Trust, but each party shall bear the expenses
incurred by it incidental to the preparation and carrying out of this Agreement.


12.  AMENDMENTS

     This Agreement may be amended, modified or supplemented in such manner as
may be mutually agreed upon in writing by the authorized officers of the Trust.
However, following the meeting of shareholders of the Acquired Fund held
pursuant to Paragraph 5.2 of this Agreement, no such amendment may have the
effect of changing the provisions regarding the method for determining the
number of Acquiring Fund Shares to be received by the Acquired Fund shareholders
under this Agreement to the detriment of such shareholders without their further
approval; provided that nothing contained in this Article 12 shall be construed
to prohibit the parties from amending this Agreement to change the Closing Date.

provisions of this Agreement shall be in writing and shall be given by prepaid

(a) Expenses reflect a temporary agreement by the Fund's investment adviser to
    limit expenses, not including transfer agent fees, Rule 12b-1 fees or any
    other class-specific expenses. Without such a limitation, the management
    fee, other expenses and total fund operating expenses of the Class A and
    Class B shares, respectively, would have been estimated as 0.40% and 0.40%;
    0.72% and 0.72%; and 1.37% and 2.02%.
  * No sales charge is payable at the time of purchase on investments of $1
    million or more, but for these investments a contingent deferred sales
    charge may be imposed, in the event of certain redemption transactions
    within one year of purchase.
 ** The amount of the 12b-1 fee used to cover service expenses will be up to
    0.25% of the Class's average net assets, and the remaining portion will be
    used to cover distribution expenses. The Fund has determined to pay Class B
    Rule 12b-1 fees to 0.90% of average net assets attributable to Class B until
    December 31, 1996, after which these fees may be increased to as much as
    1.00% of such assets and total Fund operating expenses would be 2.12% of
    such assets.
*** Other Expenses include transfer agent, legal, audit, custody and other
    expenses.

INVESTMENT OBJECTIVE AND POLICIES
The Fund's investment objective is to achieve a high level of current income,
consistent with preservation of capital and maintenance of liquidity. The Fund
seeks to achieve its investment objective by investing primarily in U.S.
Government securities, including mortgage-backed securities issued or guaranteed
by U.S. Government agencies. The Fund may also invest in medium-term debt
obligations of governmental issuers. Under normal market conditions, the Fund
intends to maintain a weighted average remaining maturity or remaining average
life of three to ten years. There is no assurance that the Fund will achieve its
investment objective.
 
- -------------------------------------------------------------------------------
                   THE FUND SEEKS TO ACHIEVE A HIGH LEVEL OF
                   CURRENT INCOME, CONSISTENT WITH
                   PRESERVATION OF CAPITAL AND MAINTENANCE OF
                   LIQUIDITY.
- -------------------------------------------------------------------------------
 
Under normal market conditions, the Fund intends to invest primarily (at least
65% of its total assets) in U.S. Government securities. U.S. Government
securities consist of the following:
 
1. U.S. Treasury obligations, which differ only in their interest rates,
   maturities and time of issuance, including U.S. Treasury bills (maturity of
   one year or less), U.S. Treasury notes (maturity of one to ten years), and
   U.S. Treasury bonds (generally maturities greater than ten years); and
 
2. Obligations issued or guaranteed by the U.S. Government, its agencies or
   instrumentalities which are supported by: (i) the full faith and credit of
   the U.S. Government (e.g., securities issued by the Government National
   Mortgage Association ("Ginnie Maes")); (ii) the right of the issuer to borrow
   an amount limited to a specific line of credit from the U.S. Government
   (e.g., securities of the Federal Home Loan Bank Board); or (iii) the credit
   of the instrumentality (e.g., bonds issued by the Federal National Mortgage
   Association ("Freddie Macs") or the Federal National Mortgage Association
   ("Fannie Maes")).
 
   
Ginnie Maes, Freddie Macs and Fannie Maes are mortgage-backed securities which
provide monthly payments that are, in effect, a "pass-through" of the monthly
interest and principal payments (including prepayments) made by the individual
borrowers on the pooled mortgage loans. The Fund's investments in mortgage-
backed securities may also include certain classes of multiple class
collateralized mortgage obligations and "stripped" mortgage-backed securities
("SMBS"). During periods of declining interest rates, principal and interest on
mortgage-backed securities may be prepaid at faster-than-expected rates. The
proceeds of these prepayments typically can only be invested in lower-yielding
securities. Therefore, mortgage-backed securities may be less effective at
maintaining yields during periods of declining interest rates than traditional
debt obligations of similar maturity. Different types of mortgage-backed
securities are subject to different combinations of prepayment, extension,
interest rate and/or other market risks. See "Investments, Techniques and Risk
Factors" for a further discussion of U.S. Government securities and these risks.
    
   
Under normal conditions, the Fund may invest the remainder of its assets in
other U.S. Government securities and asset-backed securities and debt
obligations of corporate issuers each of which is rated in the highest rating
category by a
    
 
                                        4
<PAGE>   63
nationally recognized statistical rating organization or, if unrated, determined
by the investment adviser to be of comparable quality.
 
   
The Fund may also buy and sell options contracts, financial futures contracts
and options on these futures contracts for hedging and non-hedging purposes.
These contracts may be based on securities and securities indices. All of the
Fund's futures contracts and options on futures contracts will be traded on a
U.S. commodity exchange or board of trade.
    
 
Options, futures contracts and mortgage-backed securities are generally
considered to be "derivative" instruments because they derive their value from
the performance of an underlying asset, index or other economic benchmark. See
"Investments, Techniques and Risk Factors" for additional discussion of
derivative instruments.
 
The Fund may also lend its portfolio securities; enter into repurchase
agreements, mortgage dollar rolls and reverse repurchase agreements; purchase
securities on a forward commitment or when-issued basis; and purchase restricted
and illiquid securities.
 
See "Investments, Techniques and Risk Factors" for more information about the
Fund's investments.
 
The Fund has adopted certain investment restrictions which are enumerated in
detail in the Statement of Additional Information where they are classified as
fundamental or nonfundamental. Those restrictions designated as fundamental may
not be changed without shareholder approval. The Fund's investment objective and
its policies, including its policy of investing at least 65% of its assets in
U.S. Government securities, are nonfundamental and may be changed by a vote of
the Trustees without shareholder approval.
 
- -------------------------------------------------------------------------------
                   THE FUND FOLLOWS CERTAIN POLICIES WHICH
                   MAY HELP TO REDUCE INVESTMENT RISK.
- -------------------------------------------------------------------------------
 
The primary consideration in choosing brokerage firms to carry out the Fund's
transactions is execution at the most favorable prices, taking into account the
broker's professional ability and quality of service. Consideration may also be
given to the broker's sales of Fund shares. Pursuant to procedures determined by
the Trustees, the Fund's investment adviser, John Hancock Advisers, Inc. (the
"Adviser"), may place securities transactions with brokers affiliated with the
Adviser. Affiliated brokers include Tucker Anthony Incorporated, Sutro and
Company, Inc. and John Hancock Distributors, Inc., which are indirectly owned by
the John Hancock Mutual Life Insurance Company (the "Life Company"), which in
turn indirectly owns the Adviser.

ORGANIZATION AND MANAGEMENT OF THE FUND
   
The Fund is a diversified series of the Trust, an open-end management investment
company organized as a Massachusetts business trust in 1984. The Trust reserves
the right to create and issue a number of series of shares, or funds or classes
of these series, which are separately managed and have different investment
objectives. The Trustees have authorized the issuance of two classes of the
Fund, designated as Class A and Class B. The shares of each class represent an
interest in the same portfolio of investments of the Fund. Each class has equal
rights as to voting, redemption, dividends and liquidation. However, each class
bears different distribution and transfer agent fees and other expenses. Also,
Class A and Class B shareholders have exclusive voting rights with respect to
their distribution plans. The Trust is not required and does not intend to hold
annual meetings of shareholders, although special meetings may be held for such
purposes as electing or removing Trustees, changing fundamental policies or
approving a management contract. The Fund, under certain circumstances, will
assist in shareholder communications with other Fund shareholders.
    
 
- -------------------------------------------------------------------------------
                   THE TRUSTEES ELECT OFFICERS AND RETAIN THE
                   INVESTMENT ADVISER WHO IS RESPONSIBLE FOR
                   THE DAY-TO-DAY OPERATIONS OF THE FUND,
                   SUBJECT TO THE TRUSTEES' POLICIES AND
                   SUPERVISION.
- -------------------------------------------------------------------------------
 
The Adviser was organized in 1968 and is a wholly-owned indirect subsidiary of
the Life Company, a financial services company. The Adviser provides the Fund,
and other investment companies in the John Hancock group of funds, with
investment research and portfolio management services. John Hancock Funds, Inc.
("John Hancock Funds") distributes shares for all of the John Hancock funds
through brokers which have agreements with John Hancock Funds ("Selling
Brokers"). Certain Fund officers are also officers of the Adviser and John
Hancock Funds.
 
- -------------------------------------------------------------------------------
                   JOHN HANCOCK ADVISERS, INC. ADVISES
                   INVESTMENT COMPANIES HAVING AN AGGREGATE
                   NET ASSET VALUE OF MORE THAN $13 BILLION.
- -------------------------------------------------------------------------------
 
   
The Fund is managed by the Adviser's government team, and no single person is
primarily responsible for making recommendations to the team.
    
 
In order to avoid any conflict with portfolio trades for the Fund, the Adviser
and the Fund have adopted extensive restrictions on personal securities trading
by personnel of the Adviser and its affiliates. Some of these restrictions are:
preclearance for all personal trades and a ban on the purchase of initial public
offerings, as well as contributions to specified charities of profits on
securities held for less than 91 days. These restrictions are a continuation of
the basic principle that the interests of the Fund and its shareholders come
first.
 
ALTERNATIVE PURCHASE ARRANGEMENTS
 
You can purchase shares of the Fund at a price equal to their net asset value
per share plus a sales charge. At your election, this charge may be imposed
either at the time of the purchase (see "Initial Sales Charge Alternative --
Class A shares") or on a contingent deferred basis (the "Contingent Deferred
Sales Charge Alternative -- Class B shares"). If you do not specify on your
account application the class of shares you are purchasing, it will be assumed
that you are investing in Class A shares.
 
- -------------------------------------------------------------------------------
                   AN ALTERNATIVE PURCHASE PLAN ALLOWS YOU TO
                   CHOOSE THE METHOD OF PAYMENT THAT IS BEST
                   FOR YOU.
- -------------------------------------------------------------------------------
 
                                        6
<PAGE>   65
CLASS A SHARES.  If you elect to purchase Class A shares, you will incur an
initial sales charge unless the amount of your purchase is $1 million or more.
If you purchase $1 million or more of Class A shares, you will not be subject to
an initial sales charge, but you will incur a sales charge if you redeem your
shares within one year of purchase. Class A shares are subject to ongoing
distribution and service fees at a combined annual rate of up to 0.25% of the
Fund's average daily net assets attributable to the Class A shares. Certain
purchases of Class A shares qualify for reduced initial sales charges. See
"Share Price -- Qualifying for a Reduced Sales Charge."
 
- -------------------------------------------------------------------------------
                   INVESTMENTS IN CLASS A SHARES ARE SUBJECT
                   TO AN INITIAL SALES CHARGE.
- -------------------------------------------------------------------------------
 
   
CLASS B SHARES.  You will not incur a sales charge when you purchase Class B
shares, but the shares are subject to a sales charge if you redeem them within
six years of purchase (the "contingent deferred sales charge" or the "CDSC").
Class B shares are subject to ongoing distribution and service fees at a
combined annual rate of up to 1.00% of the Fund's average daily net assets
attributable to the Class B shares. John Hancock Funds and the Fund have agreed
until further notice to limit the Fund's 12b-1 fee for Class B shares to 0.90%
of the Fund's Class B average daily net assets. Investing in Class B shares
permits all of your dollars to work from the time you make your investment, but
the higher ongoing distribution fee will cause these shares to have higher
expenses than those of Class A shares. To the extent that any dividends are paid
by the Fund, these higher expenses will also result in lower dividends than
those paid on Class A shares.
    
 
- -------------------------------------------------------------------------------
                   INVESTMENTS IN CLASS B SHARES ARE SUBJECT
                   TO A CONTINGENT DEFERRED SALES CHARGE.
- -------------------------------------------------------------------------------
 
Class B shares are not available for full-service defined contribution plans
administered by Investor Services or the Life Company that had more than 100
eligible employees at the inception of the Fund account.
 
FACTORS TO CONSIDER IN CHOOSING AN ALTERNATIVE.  The alternative purchase
arrangement allows you to choose the most beneficial way to buy shares, given
the amount of your purchase, the length of time you expect to hold your shares
and other circumstances. You should consider whether, during the anticipated
life of your Fund investment, the CDSC and accumulated fees on Class B shares
would be less than the initial sales charge and accumulated fees on Class A
shares purchased at the same time, and to what extent this differential would be
offset by the Class A shares' lower expenses. To help you make this
determination, the table under the caption "Expense Information" on the inside
cover page of this Prospectus shows examples of the charges applicable to each
class of shares. Class A shares will normally be more beneficial if you qualify
for reduced sales charges. See "Share Price -- Qualifying for a Reduced Sales
Charge."
 
- -------------------------------------------------------------------------------
                   YOU SHOULD CONSIDER WHICH CLASS OF SHARES
                   WOULD BE MORE BENEFICIAL TO YOU.
- -------------------------------------------------------------------------------
 
Class A shares are subject to lower distribution fees and, accordingly, pay
correspondingly higher dividends per share, to the extent any dividends are
paid. However, because initial sales charges are deducted at the time of
purchase, you would not have all of your funds invested initially and,
therefore, would initially own fewer shares. If you do not qualify for reduced
initial sales charges and expect to maintain your investment for an extended
period of time, you might consider purchasing Class A shares. This is because
the accumulated distribution and service charges on Class B shares may exceed
the initial sales charge and
 
                                        7
<PAGE>   66
 
accumulated distribution and service charges on Class A shares during the life
of your investment.
 
Alternatively, you might determine that it is more advantageous to purchase
Class B shares to have all of your funds invested initially. However, you will
be subject to higher distribution and service fees and, for a six-year period, a
CDSC.
 
In the case of Class A shares, the distribution expenses that John Hancock Funds
incurs in connection with the sale of the shares will be paid from the proceeds
of the initial sales charge and ongoing distribution and service fees. In the
case of Class B shares, the expenses will be paid from the proceeds of the
ongoing distribution and service fees, as well as from the CDSC incurred upon
redemption within six years of purchase. The purpose and function of the Class B
shares' CDSC and ongoing distribution and service fees are the same as those of
the Class A shares' initial sales charge and ongoing distribution and service
fees. Sales personnel distributing the Fund's shares may receive different
compensation for selling each class of shares.
 
Dividends, if any, on Class A and Class B shares will be calculated in the same
manner, at the same time and on the same day. They also will be in the same
amount, except for differences resulting from each class bearing only its own
distribution and service fees, shareholder meeting expenses and any incremental
transfer agency costs. See "Dividends and Taxes."
 
THE FUND'S EXPENSES
 
For managing its investment and business affairs, the Fund pays a monthly fee to
the Adviser equal to 0.40%.
 
   
During the Fund's fiscal year ended March 31, 1995, the advisory fee paid by the
Fund was equal to 0.20% of the Fund's average daily net assets, reflecting the
agreement by the Adviser and the former investment adviser to reduce operating
expenses and not to impose a portion of the management fee during that year. The
Adviser has temporarily agreed to continue to limit the Fund's aggregate
operating expenses until December 31, 1996 and not to impose its management fee
or to make other arrangements to the extent necessary to limit the total of the
management fees and the aggregate operating expenses of the Fund (not including
transfer agent fees, fees payable by the Fund under a Rule 12b-1 plan, or any
other class-specific expenses) to 0.35% of the average net assets attributable
to the Class A and Class B shares, respectively.
    
   
The Class A and Class B shareholders have adopted distribution plans (each a
"Plan") pursuant to Rule 12b-1 under the Investment Company Act of 1940 (the
"1940 Act"). Under these Plans, the Fund will pay distribution and service fees
at an aggregate annual rate of up to 0.25% of the Class A shares' average daily
net assets and an aggregate annual rate of 1.00% of the Class B shares' average
daily net assets. The Fund has temporarily determined to limit the distribution
and services fees pursuant to the Class B Plan to 0.90% of average daily net
assets. In each case, up to 0.25% is for service expenses and the remaining
amount is for distribution expenses. The distribution fees will be used to
reimburse John

and (v) with respect to Class B shares only, interest expenses on unreimbursed
distribution expenses. The service fees will be used to compensate Selling
Brokers for providing personal and account maintenance services to
shareholders.
 
In the event John Hancock Funds is not fully reimbursed for payments it makes or
expenses it incurs under the Class A Plan, these expenses will not be carried
beyond one year from the date they were incurred. Unreimbursed expenses under
the Class B Plan will be carried forward together with interest on the balance
of these unreimbursed expenses.
 
   
For the fiscal year ended March 31, 1995, an aggregate of $253,107 of
distribution expenses or 2.30% of the average net assets of the Fund's Class B  
shares was not reimbursed or recovered by John Hancock Funds through the
receipt of deferred sales charges or Rule 12b-1 fees in prior periods.
    
 
Information on the Fund's total expenses is in the Financial Highlights section
of this Prospectus.
 
DIVIDENDS AND TAXES
DIVIDENDS.  The Fund generally declares daily and distributes monthly dividends
representing all or substantially all of its net investment income. The Fund
will distribute net realized long-term and short-term capital gains, if any, at
least annually.
 
- -------------------------------------------------------------------------------
                   THE FUND GENERALLY DECLARES DIVIDENDS
                   DAILY AND DISTRIBUTES THEM MONTHLY.
- -------------------------------------------------------------------------------
 
Dividends are reinvested in additional shares of your class unless you elect the
option to receive them in cash. If you elect the cash option and the U.S. Postal
Service cannot deliver your checks, your election will be converted to the
reinvestment option. Because of the higher expenses associated with Class B
shares, any dividend on these shares will be lower than those on the Class A
shares. See "Share Price."
 
TAXATION.  Dividends from the Fund's net investment income and net short-term
capital gains are taxable to you as ordinary income and dividends from the
Fund's net long-term capital gains are taxable as long-term capital gain. These
dividends are taxable whether you take them in cash or reinvest in additional
shares. Certain dividends may be paid in January of a given year but may be
taxable as if you received them the previous December.
 
The Fund has qualified and intends to continue to qualify as a regulated
investment company under Subchapter M of the Internal Revenue Code of 1986, as
amended (the "Code"). As a regulated investment company, the Fund will not be
subject to
 
                                        9
<PAGE>   68
 
Federal income tax on any net investment income or net realized capital gains
that are distributed to its shareholders within the time period prescribed by
the Code. When you redeem (sell) or exchange shares, you may realize a taxable
gain or loss.
 
On the account application you must certify that the social security or other
taxpayer identification number you provide is correct and that you are not
subject to backup withholding of Federal income tax. If you do not provide this
information or are otherwise subject to this withholding, the Fund may be
required to withhold 31% of your dividends and the proceeds of redemptions and
exchanges.
 
In addition to Federal taxes, you may be subject to state, local or foreign
taxes with respect to your investment in and distributions from the Fund. In
some states, a portion of the Fund's dividends that represents interest received
by the Fund on direct U.S. Government obligations may be exempt from tax.
Non-U.S. shareholders and tax-exempt shareholders are subject to different tax
treatment not described above. You should consult your tax adviser for specific
advice.
 
PERFORMANCE
Yield reflects the Fund's rate of income on portfolio investments as a
percentage of its share price. Yield is computed by annualizing the result of
dividing the net investment income per share over a 30 day period by the maximum
offering price per share on the last day of that period. Yield is also
calculated according to accounting methods that are standardized for all stock
and bond funds. Because yield accounting methods differ from the methods used
for other accounting purposes, the Fund's yield may not equal the income paid on
shares or the income reported in the Fund's financial statements.
 
- -------------------------------------------------------------------------------
                   THE FUND MAY ADVERTISE ITS YIELD AND TOTAL
                   RETURN.
- -------------------------------------------------------------------------------
 
The Fund's total return shows the overall dollar or percentage change in value
of a hypothetical investment in the Fund, assuming the reinvestment of all
dividends. Cumulative total return shows the Fund's performance over a period of
time. Average annual total return shows the cumulative return divided over the
number of years included in the period. Because average annual total return
tends to smooth out variations in the Fund's performance, you should recognize
that it is not the same as actual year-to-year results.
 
   
Both total return and yield calculations for Class A shares generally include
the effect of paying the maximum sales charge of 3% (except as shown in "The
Fund's Financial Highlights"). Investments at lower sales charges would result
in higher performance figures. Total return and yield for Class B shares reflect
the deduction of the applicable CDSC imposed on a redemption of shares held for
the applicable period. All calculations assume that all dividends are reinvested
at net asset value on the reinvestment dates during the periods. Total return
and yield of Class A and Class B shares will be calculated separately and,
because each class is subject to different expenses, the total return may differ
with respect to that class for the same period. The relative performance of the
Class A and Class B shares will be affected by a variety of factors, including
the higher operating expenses attributable to the Class B shares, whether the
Fund's investment
    
 
                                       10
<PAGE>   69
performance is better in the earlier or later portions of the period measured
and the level of net assets of the classes during the period. The Fund will
include the total return of Class A and Class B shares in any advertisement or
promotional materials including Fund performance data. The value of Fund shares,
when redeemed, may be more or less than their original cost. Both yield and
total return are historical calculations, and are not an indication of future
performance. See "Alternative Purchase Arrangements -- Factors to Consider in
Choosing an Alternative."

SHARE PRICE
The net asset value per share ("NAV") is the value of one share. The NAV is
calculated by dividing the net assets of each class by the number of outstanding
shares of that class. The NAV of each class can differ. Securities in the Fund's
portfolio are valued on the basis of market quotations, valuations provided by
independent pricing services or at fair value as determined in good faith
according to procedures approved by the Trustees. Short-term debt investments
maturing within 60 days are valued at amortized cost, which the Trustees have
determined approximates market value. The NAV is calculated once daily as of the
close of regular trading on the New York Stock Exchange (the "Exchange")
(generally at 4:00 P.M., New York time) on each day that the Exchange is open.
 
- -------------------------------------------------------------------------------
                   THE OFFERING PRICE OF YOUR SHARES IS THEIR
                   NET ASSET VALUE PLUS A SALES CHARGE, IF
                   APPLICABLE, WHICH WILL VARY WITH THE
                   PURCHASE ALTERNATIVE YOU CHOOSE.
- -------------------------------------------------------------------------------
 
Shares of the Fund are sold at the offering price based on the NAV computed
after your investment request is received in good order by John Hancock Funds.
If you buy shares of the Fund through a Selling Broker, the Selling Broker must
receive your investment before the close of regular trading on the Exchange and
transmit it
 
                                       12

to John Hancock Funds before its close of business to receive that day's
offering price.

  (*) Upon notice to Selling Brokers with whom it has sales agreements, John
      Hancock Funds may reallow an amount up to the full applicable sales
      charge. A Selling Broker to whom substantially the entire sales charge is
      reallowed or who receives these incentives may be deemed to be an
      underwriter under the Securities Act of 1933. Other than distribution and
      service fees, the Fund does not bear distribution expenses.
    
 (**) No sales charge is payable at the time of purchase of Class A shares of $1
      million or more, but a CDSC may be imposed in the event of certain
      redemption transactions within one year of purchase.
 
(***) John Hancock Funds may pay a commission and the first year's service fee
      (as described in (+) below) to Selling Brokers who initiate and are
      responsible for purchases of $1 million or more in aggregate as follows:
      1% on sales to $4,999,999, 0.50% on the next $5 million and 0.25% on
      amounts of $10 million and over.
 
  (+) At the time of sale, John Hancock Funds pays to Selling Brokers the first
      year's service fee in advance in an amount equal to 0.25% of the net
      assets invested in the Fund, and thereafter, it pays the service fee
      periodically in arrears in an amount up to 0.25% of the Fund's average
      annual net assets. Selling Brokers receive the fee as compensation for
      providing personal and account maintenance services to shareholders.
</TABLE>
 
Sales charges ARE NOT APPLIED to any dividends that are reinvested in additional
Class A shares of the Fund.
 
In addition, John Hancock Funds will pay certain affiliated Selling Brokers at
an annual rate of up to 0.05% of the daily net assets of accounts attributable
to these brokers.
 
Under certain circumstances described below, investors in Class A shares may be
entitled to pay reduced sales charges. See "Qualifying for a Reduced Sales
Charge."
 
CONTINGENT DEFERRED SALES CHARGE -- INVESTMENTS OF $1 MILLION OR MORE IN CLASS A
SHARES.  Purchases of $1 million or more of Class A shares will be made at net
asset value with no initial sales charge, but if the shares are redeemed within

</TABLE>
 
Existing full service clients of the Life Company who were group annuity
contract holders as of September 1, 1994 and participant-directed defined
contribution plans with at least 100 eligible employees at the inception of the
Fund account may purchase Class A shares with no initial sales charge. However,
if the shares are redeemed within 12 months after the end of the calendar year
in which the purchase was made, a CDSC will be imposed at the above rate.
 
The CDSC will be assessed on an amount equal to the lesser of the current market
value or the original purchase cost of the redeemed Class A shares. Accordingly,
no CDSC will be imposed on increases in account value above the initial purchase
price, including any distributions which have been reinvested in additional
Class A shares.
 
In determining whether a CDSC applies to a redemption, the calculation will be
determined in a manner that results in the lowest possible rate being charged.
Therefore, it will be assumed that the redemption is first made from any shares
in your account that are not subject to the CDSC. The CDSC is waived on
redemptions in certain circumstances. See "Waiver of Contingent Deferred Sales
Charges" below.
 
   
QUALIFYING FOR A REDUCED SALES CHARGE.  If you invest more than $100,000 in
Class A shares of the Fund or a combination of funds within the John Hancock
family of funds (except John Hancock Money Market Fund), you may qualify for a
reduced sales charge on your investments in Class A shares through a LETTER OF
INTENTION. You may also be able to use the ACCUMULATION PRIVILEGE and the
COMBINATION PRIVILEGE to take advantage of the value of your previous
investments in Class A shares of the John Hancock funds in meeting the
breakpoints for a reduced sales charge. For the ACCUMULATION PRIVILEGE and
COMBINATION PRIVILEGE, the applicable sales charge will be based on the total
of:

                   YOU MAY QUALIFY FOR A REDUCED SALES CHARGE
                   ON YOUR INVESTMENT IN CLASS A SHARES.
- -------------------------------------------------------------------------------
 
1. Your current purchase of Class A shares of the Fund.
 
2. The net asset value (at the close of business on the previous day) of (a) all
   Class A shares of the Fund you hold, and (b) all Class A shares of any other
   John Hancock funds you hold; and
 
3. The net asset value of all shares held by another shareholder eligible to
   combine his or her holdings with you into a single "purchase."

EXAMPLE:
If you hold Class A shares of a John Hancock fund with a net asset value of
$20,000 and, subsequently, invest $80,000 in Class A shares of the Fund, the
sales charge on this subsequent investment would be 2.50% and not 3.00%. (The
rate that would otherwise be applicable to investments of less than $100,000.
See "Initial Sales Charge Alternative -- Class A Shares.")
 
If you are in one of the following categories, you may purchase Class A shares
of the Fund without paying a sales charge:
- - A Trustee or officer of the Fund; a Director or officer of the Adviser and its
  affiliates or Selling Brokers; employees or sales representatives of any of
  the foregoing; retired officers, employees or Directors of any of the
  foregoing; a member of the immediate family of any of the foregoing; or any
  fund, pension, profit sharing or other benefit plan for the individuals
  described above.
 
- -------------------------------------------------------------------------------
                   CLASS A SHARES MAY BE AVAILABLE WITHOUT A
                   SALES CHARGE TO CERTAIN INDIVIDUALS AND
                   ORGANIZATIONS.
- -------------------------------------------------------------------------------
- - Any state, county, city or any instrumentality, department, authority, or
  agency of these entities that is prohibited by applicable investment laws from
  paying a sales charge or commission when it purchases shares of any registered
  investment management company.*
- - A bank, trust company, credit union, savings institution or other type of
  depository institution, its trust departments or common trust funds if it is
  purchasing $1 million or more for non-discretionary customers or accounts.*
- - A broker, dealer or registered investment adviser that has entered into an
  agreement with John Hancock Funds providing specifically for the use of Fund
  shares in fee-based investment products made available to their clients.
- - A former participant in an employee benefit plan with John Hancock Funds, when
  he/she withdraws from his/her plan and transfers any or all of his/her plan
  distributions directly to the Fund.
 
- ------------------
*For investments made under these provisions, John Hancock Funds may make a
 payment out of its own resources to the Selling Broker in an amount not to
 exceed 0.25% of the amount invested.
 
Class A shares of the Fund may be purchased without an initial sales charge in
connection with certain liquidation, merger or acquisition transactions
involving other investment companies or personal holding companies.
 
CONTINGENT DEFERRED SALES CHARGE ALTERNATIVE -- CLASS B SHARES.  Class B shares
are offered at net asset value per share without a sales charge so that your
entire initial investment will go to work at the time of purchase. However,
Class B shares redeemed within four years of purchase will be subject to a CDSC
at the rates set forth below. This charge will be assessed on an amount equal to
the lesser of the current market value or the original purchase cost of the
shares being redeemed. Accordingly, you will not be assessed a CDSC on increases
in account value above the initial purchase price, including shares derived from
dividend reinvestment.
 
In determining whether a CDSC applies to a redemption, the calculation will be
determined in a manner that results in the lowest possible rate being charged.
It
 
                                       15

will be assumed that your redemption comes first from shares you have held
beyond the four-year CDSC redemption period or those you acquired through
reinvestment of dividends, and next from the shares you have held the longest
during the four-year period. The CDSC is waived on redemptions in certain
circumstances. See the discussion "Waiver of Contingent Deferred Sales Charges"
below.
 
<TABLE>
EXAMPLE:
You have purchased 100 shares at $10 per share. The second year after your
purchase, your investment's net asset value per share has increased by $2 to
$12, and you have gained 10 additional shares through dividend reinvestment. If
you redeem 50 shares at this time, your CDSC will be calculated as follows:
 
<S>                                                                          <C>
- - Proceeds of 50 shares redeemed at $12 per share........................    $600
- - Minus proceeds of 10 shares not subject to CDSC because they were
  acquired through dividend reinvestment (10 x $12)......................    -120
- - Minus appreciation on remaining shares, also not subject to CDSC (40 x
  $2)....................................................................     -80
                                                                             ----
- - Amount subject to CDSC.................................................    $400
</TABLE>
 
Proceeds from the CDSC are paid to John Hancock Funds. John Hancock Funds uses
part of them to defray its expenses related to providing the Fund with
distribution services connected to the sale of Class B shares, such as
compensating Selling Brokers for selling these shares. The combination of the
CDSC and the distribution and service fees makes it possible for the Fund to
sell Class B shares without deducting a sales charge at the time of the
purchase.
 
The amount of the CDSC, if any, will vary depending on the number of years from
the time you purchase your Class B shares until the time you redeem them. Solely
for the purposes of determining this holding period, any payments you make
during the month will be aggregated and deemed to have been made on the last day
of the month.

A commission equal to 2.75% of the amount invested and a first year's service
fee equal to 0.25% of the amount invested are paid to Selling Brokers. The
initial service fee is paid in advance at the time of sale for the provision of
personal and account maintenance services to shareholders during the twelve
months following the sale, and thereafter the service fee is paid in arrears.

WAIVER OF CONTINGENT DEFERRED SALES CHARGES.  The CDSC will be waived on
redemptions of Class B shares and of Class A shares that are subject to a CDSC,
unless indicated otherwise, in these circumstances:
 
- - Redemptions of Class B shares made under a Systematic Withdrawal Plan (see
  "How to Redeem Shares"), as long as your annual redemptions do not exceed 10%
  of your account value at the time you establish your Systematic Withdrawal
  Plan and 10% of the value of your subsequent investments (less redemptions) in
  that account at the time you notify Investor Services. This waiver does not
  apply to Systematic Withdrawal Plan redemptions of Class A shares that are
  subject to a CDSC.
- -------------------------------------------------------------------------------
                   UNDER CERTAIN CIRCUMSTANCES, THE CDSC ON
                   CLASS B AND CERTAIN CLASS A SHARE
                   REDEMPTIONS WILL BE WAIVED.
- -------------------------------------------------------------------------------
- - Redemptions made to effect distributions from an Individual Retirement Account
  either before or after age 59 1/2, as long as the distributions are based on
  the life expectancy or the joint-and-last survivor life expectancy of you and
  your beneficiary. These distributions must be free from penalty under the
  Code.
 
- - Redemptions made to effect mandatory distributions under the Code after age
  70 1/2 from a tax-deferred retirement plan.
 
- - Redemptions made to effect distributions to participants or beneficiaries from
  certain employer-sponsored retirement plans including those qualified under
  Section 401(a) of the Code, custodial accounts under Section 403(b)(7) of the
  Code and deferred compensation plans under Section 457 of the Code. The waiver
  also applies to certain returns of excess contributions made to these plans.
  In all cases, the distributions must be free from penalty under the Code.
 
- - Redemptions due to death or disability.
 
- - Redemptions made under the Reinvestment Privilege, as described in "Additional
  Services and Programs" of this Prospectus.
 
- - Redemptions made pursuant to the Fund's right to liquidate your account if you
  have less than $100 invested in the Fund.
 
- - Redemptions made in connection with certain liquidation, merger or acquisition
  transactions involving other investment companies or personal holding
  companies.
 
- - Redemptions from certain IRA and retirement plans that purchased shares prior
  to October 1, 1992.
 
If you qualify for a CDSC waiver under one of these situations, you must notify
Investor Services either directly or through your Selling Broker at the time you
make your redemption. The waiver will be granted once Investor Services has
confirmed that you are entitled to the waiver.

CONVERSION OF CLASS B SHARES.  Your Class B shares and an appropriate portion of
reinvested dividends on those shares will be converted into Class A shares
automatically. This will occur no later than the month following four years
after the shares were purchased, and will result in lower annual distribution
fees. If you exchanged Class B shares into the Fund from another John Hancock
fund, the calculation will be based on the time you purchased the shares in the
original fund. The Fund has been advised that the conversion of Class B shares
to Class A shares should not be taxable for Federal income tax purposes and
should not change a shareholder's tax basis or tax holding period for the
converted shares.
 
HOW TO REDEEM SHARES
You may redeem all or a portion of your shares on any business day. Your shares
will be redeemed at the next NAV calculated after your redemption request is
received in good order by Investor Services, less any applicable CDSC. The Fund
may hold payment until it is reasonably satisfied that investments recently made
by check or Invest-by-Phone have been collected (which may take up to 10
calendar days).
- -------------------------------------------------------------------------------
                   TO ASSURE ACCEPTANCE OF YOUR REDEMPTION
                   REQUEST, PLEASE FOLLOW THESE PROCEDURES.
- -------------------------------------------------------------------------------
   
Once your shares are redeemed, the Fund generally sends you payment on the next
business day. When you redeem your shares, you may realize a taxable gain or
loss depending usually on the difference between what you paid for them and what
you receive for them, subject to certain tax rules. Under unusual circumstances,
the Fund may suspend redemptions or postpone payment as permitted by Federal
securities laws, which could be up to seven days.

    BY TELEPHONE  All Fund shareholders are automatically eligible for the
                  telephone redemption privilege. Call 1-800-225-5291, from 8:00
                  A.M. to 4:00 P.M. (New York time), Monday through Friday,
                  excluding days on which the Exchange is closed. Investor Services
                  employs the following procedures to confirm that instructions
                  received by telephone are genuine. Your name, the account number,
                  taxpayer identification number applicable to the account and
                  other relevant information may be requested. In addition,
                  telephone instructions are recorded.

                  You may redeem up to $100,000 by telephone, but the address on
                  the account must not have changed for the last thirty days. A
                  check will be mailed to the exact name(s) and address shown on
                  the account.

                  If reasonable procedures, such as those described above, are not
                  followed, the Fund may be liable for any loss due to unauthorized
                  or fraudulent telephone instructions. In all other cases, neither
                  the Fund nor Investor Services will be liable for any loss or
                  expense for acting upon telephone instructions made in accordance
                  with the telephone transaction procedures mentioned above.

                  Telephone redemption is not available for IRAs or other
                  tax-qualified retirement plans or shares of the Fund that are in
                  certificated form.

                  During periods of extreme economic conditions or market changes,
                  telephone requests may be difficult to implement due to a large
                  volume of calls. During these times, you should consider placing
                  redemption requests in writing or use EASI-Line. EASI-Line's
                  telephone number is 1-800-338-8080.

A signature guarantee is a widely accepted way to protect you and the Fund by
verifying the signature on your request. It may not be provided by a notary
public. If the net asset value of the shares redeemed is $100,000 or less, John
Hancock Funds may guarantee the signature. The following institutions may
provide you with a signature guarantee, provided that the institution meets
credit standards established by Investor Services: (i) a bank; (ii) a
securities broker or dealer, including a government or municipal securities
broker or dealer, that is a member of a clearing corporation or meets certain
net capital requirements; (iii) a credit union having authority to issue
signature guarantees; (iv) a savings and loan association, a building and loan  
association, a cooperative bank, a federal savings bank or association; or (v)
a national securities exchange, a registered securities exchange or a clearing
agency.

- -------------------------------------------------------------------------------
If you have certificates for your shares, you must submit them with your stock
power or a letter of instructions. Unless you specify to the contrary, any      
outstanding Class A shares will be redeemed before Class B shares. You may not
redeem certificated shares by telephone.

Due to the proportionately high cost of maintaining small accounts, the Fund
reserves the right to redeem at net asset value all shares in an account which
holds less than $100 (except accounts under retirement plans) and to mail the   
proceeds to the shareholder, or the transfer agent may impose an annual fee of
$10.00. No account will be involuntarily redeemed or additional fee imposed, if
the value of the account is in excess of the Fund's minimum initial investment
or if the value of the account falls below the required minimum as a result of
market action. No CDSC will be imposed on involuntary redemptions of shares.

Shareholders will be notified before these redemptions are to be made or this
fee is imposed, and will have 30 days to purchase additional shares to bring
their account balance up to the required minimum. Unless the number of shares   
acquired by further purchases and dividend reinvestments, if any, exceeds the
number of shares redeemed, repeated redemptions from a smaller account may
eventually trigger this policy.

ADDITIONAL SERVICES AND PROGRAMS
 
EXCHANGE PRIVILEGE
If your investment objective changes, or if you wish to achieve further
diversification, John Hancock offers other funds with a wide range of investment
goals. Contact your registered representative or Selling Broker and request a
prospectus for the John Hancock funds that interest you. Read the prospectus
carefully before exchanging your shares. You can exchange shares of each class
of the Fund only for shares of the same class of another John Hancock fund. For
this purpose, John Hancock funds with only one class of shares will be treated
as Class A, whether or not they have been so designated.
 
- -------------------------------------------------------------------------------
                   YOU MAY EXCHANGE SHARES OF THE FUND ONLY
                   FOR SHARES OF THE SAME CLASS OF ANOTHER
                   JOHN HANCOCK FUND.
- -------------------------------------------------------------------------------
 
Exchanges between funds with shares that are not subject to a CDSC are based on
their respective net asset values. No sales charge or transaction charge is
imposed. Class B shares of the Fund that are subject to a CDSC may be exchanged
into Class B shares of another John Hancock fund without incurring the CDSC;
however, these shares will be subject to the CDSC schedule of the shares
acquired (except that exchanges into the Fund, John Hancock Short-Term Strategic
Income Fund and John Hancock Limited-Term Government Fund will be subject to the
initial fund's CDSC). For purposes of computing the CDSC payable upon redemption
of shares acquired in an exchange, the holding period of the original shares is
added to the holding period of the shares acquired in an exchange. However, if
you exchange Class B shares purchased prior to January 1, 1994 for Class B
shares of any other John Hancock Fund, you will be subject to the CDSC schedule
in effect on your initial purchase date.
 
   
You may exchange Class B shares of the Fund into Class B shares of John Hancock
Money Market Fund at net asset value. However, you will continue to be subject
to a CDSC upon redemption.
    
 
The Fund reserves the right to require you to keep previously exchanged shares
(and reinvested dividends) in the Fund for 90 days before you are permitted to
execute a new exchange. The Fund may also terminate or alter the terms of the
exchange privilege, upon 60 days' notice to shareholders.
 
An exchange of shares is treated as a redemption of shares of one fund and the
purchase of shares in another for Federal income tax purposes. An exchange may
result in a taxable gain or loss.
 
When you make an exchange, your account registration in both the existing and
new account must be identical. The exchange privilege is available only in
states where the exchange can be made legally.
 
Under exchange agreements with John Hancock Funds, certain dealers, brokers and
investment advisers may exchange their clients' Fund shares, subject to the
terms of those agreements and John Hancock Funds' right to reject or suspend
those exchanges at any time. Because of the restrictions and procedures under
those agreements, the exchanges may be subject to timing limitations and other
restrictions that do not apply to exchanges requested by shareholders directly,
as described above.
 
                                       20
<PAGE>   79
Because Fund performance and shareholders can be hurt by excessive trading, the
Fund reserves the right to terminate the exchange privilege for any person or
group that, in John Hancock Funds' judgment, is involved in a pattern of
exchanges that coincide with a "market timing" strategy that may disrupt the
Fund's ability to invest effectively according to its investment objective and
policies, or might otherwise affect the Fund and its shareholders adversely. The
Fund may also temporarily or permanently terminate the exchange privilege for
any person who makes seven or more exchanges out of the Fund per calendar year.
Accounts under common control or ownership will be aggregated for this purpose.
Although the Fund will attempt to give you prior notice whenever it is
reasonably able to do so, it may impose these restrictions at any time.
 
BY TELEPHONE
1. When you complete the application for your initial purchase of Fund shares,
   you automatically authorize exchanges by telephone unless you check the box
   indicating that you do not wish to authorize telephone exchanges.
 
2. Call 1-800-225-5291. Have the account number of your current fund and the
   exact name in which it is registered available to give to the telephone
   representative.
 
3. Your name, the account number, taxpayer identification number applicable to
   the account and other relevant information may be requested. In addition,
   telephone instructions are recorded.
 
IN WRITING
1. In a letter, request an exchange and list the following:

   -- the name and class of the Fund whose shares you currently own
 
   -- your account number

   -- the name(s) in which the account is registered -- the name of the fund in
      which you wish your exchange to be invested

   -- the number of shares, all shares or dollar amount you wish to exchange

   Sign your request exactly as the account is registered.

2. Mail the request and information to:

REINVESTMENT PRIVILEGE
1. You will not be subject to a sales charge on Class A shares reinvested in
   shares of any John Hancock fund that is otherwise subject to a sales charge
   as long as you reinvest within 120 days from the redemption date. If you paid
   a CDSC upon a redemption, you may reinvest at net asset value in the same
   class of shares from which you redeemed within 120 days. Your account will be
   credited with the amount of the CDSC previously charged, and the reinvested
   shares will continue to be subject to a CDSC. For purposes of computing the
   CDSC payable upon a subsequent redemption, the holding period of the shares
   acquired through reinvestment will include the holding period of the redeemed
   shares.
- -------------------------------------------------------------------------------
                   IF YOU REDEEM SHARES OF THE FUND, YOU MAY
                   BE ABLE TO REINVEST ALL OR PART OF THE
                   PROCEEDS IN THE FUND OR ANOTHER JOHN
                   HANCOCK FUND WITHOUT PAYING AN ADDITIONAL
                   SALES CHARGE.
- -------------------------------------------------------------------------------
 
2. Any portion of your redemption may be reinvested in Fund shares or in shares
   of any of the other John Hancock funds, subject to the minimum investment
   limit of that fund.
 
3. To reinvest, you must notify Investor Services in writing. Include the Fund's
   name, the account number and class from which your shares were originally
   redeemed.
 
SYSTEMATIC WITHDRAWAL PLAN
1. You can elect the Systematic Withdrawal Plan at any time by completing the
   Account Privileges Application which is attached to this Prospectus. You can
   also obtain this application by calling your registered representative or by
   calling 1-800-225-5291.
 
2. To be eligible, you must have at least $5,000 in your account.
- -------------------------------------------------------------------------------
                   YOU CAN PAY ROUTINE BILLS FROM YOUR
                   ACCOUNT, OR MAKE PERIODIC DISBURSEMENTS OF
                   FUNDS FROM YOUR RETIREMENT ACCOUNT TO
                   COMPLY WITH IRS REGULATIONS.
- -------------------------------------------------------------------------------
 
3. Payments from your account can be made monthly, quarterly, semi-annually or
   annually or on a selected monthly basis to yourself or any other designated
   payee.
 
4. There is no limit on the number of payees you may authorize, but all payments
   must be made at the same time or intervals.
5. It is not advantageous to maintain a Systematic Withdrawal Plan concurrently
   with purchases of additional Class A or Class B shares, because you may be
   subject to initial sales charges on your purchases of Class A shares or to a
   CDSC on your redemptions of Class B shares. In addition, your redemptions are
   taxable events.
6. Redemptions will be discontinued if the U.S. Postal Service cannot deliver
   your checks or if deposits to a bank account are returned for any reason.
MONTHLY AUTOMATIC ACCUMULATION PROGRAM (MAAP)
 
1. You can authorize an investment to be automatically withdrawn each month from
   your bank for investment in Fund shares under the "Automatic Investing" and

INVESTMENTS, TECHNIQUES AND RISK FACTORS
MORTGAGE-BACKED SECURITIES.  The Fund may invest in mortgage-backed securities.
A mortgage-backed security is an obligation of an issuer which is backed by a
mortgage or pool of mortgages or a direct interest in an underlying pool of
mortgages. Some mortgage-backed securities, such as collateralized mortgage
obligations ("CMOs"), make payments of both principal and interest at a variety
of intervals; others make semiannual interest payments at a predetermined rate
and repay principal at maturity (like a typical bond). Mortgage-backed
securities are based on different types of mortgages including those on
commercial real estate or residential properties. Mortgage-backed securities may
have less potential for capital appreciation than comparable fixed-income
securities, due to the likelihood of increased prepayments of mortgages as
interest rates decline. If the
 
                                       23
<PAGE>   82
 
Fund buys mortgage-backed securities at a premium, mortgage foreclosures and
prepayments of principal by mortgagors (which may be made at any time without
penalty) may result in some loss of the Fund's principal investment to the
extent of the premium paid. The value of mortgage-backed securities may also
change due to shifts in the market's perception of issuers. In addition,
regulatory or tax changes may adversely affect the mortgage securities market as
a whole.
 
The Fund may also invest in "stripped" mortgage-backed securities ("SMBS"). SMBS
are created when a U.S. Government agency or a financial institution separates
the interest and principal components of a mortgage-backed security and sells
them as individual securities. The holder of the "principal-only" security
("PO") receives the principal payments made by the underlying mortgage-backed
security, while the holder of the "interest-only" security ("IO") receives
interest payments from the same underlying security. The prices of stripped
mortgage-backed securities may be particularly affected by changes in interest
rates. As interest rates fall, prepayment rates tend to increase, which tends to
reduce prices of IOs and increase prices of POs. Rising interest rates can have
the opposite effect. Although the markets for such securities is increasingly
liquid, the Adviser may, in accordance with guidelines adopted by the Board of
Trustees, determine that certain stripped mortgage-backed securities issued by
the U.S. Government, its agencies or instrumentalities are not readily
marketable. If so, these securities, together with privately-issued stripped
mortgage-backed securities, will be considered illiquid for purposes of the
Fund's limitation of investments of illiquid securities.
 
Other types of mortgage-backed securities will likely be developed in the
future, and the Fund may invest in them if the Adviser determines they are
consistent with the Fund's investment objectives and policies.
 
   
RESTRICTED SECURITIES.  The Fund may purchase restricted securities, including
those eligible for resale to "qualified institutional buyers" pursuant to Rule
144A under the Securities Act of 1933 (the "Securities Act"). The Trustees will
monitor the Fund's investments in these securities, focusing on certain factors,
including valuation, liquidity and availability of information. Purchases of
restricted securities are subject to an investment restriction limiting all the
Fund's illiquid securities to not more than 15% of its net assets.
    
 
   
LENDING OF SECURITIES.  The Fund may lend portfolio securities to brokers,
dealers, and financial institutions if the loan is collateralized by cash or
U.S. Government securities according to applicable regulatory requirements. The
Fund may reinvest any cash collateral in short-term securities. When the Fund
lends portfolio securities, there is a risk that the borrower may fail to return
the loaned securities. As a result, the Fund may incur a loss or, in the event
of the borrower's bankruptcy, the Fund may be delayed in or prevented from
liquidating the collateral. It is a fundamental policy of the Fund not to lend
portfolio securities having a total value in excess of 33 1/3% of its total
assets.
    
 
   
REPURCHASE AGREEMENTS, FORWARD COMMITMENTS AND WHEN-ISSUED SECURITIES.  The Fund
may enter into repurchase agreements and may purchase
    
 
                                       24
<PAGE>   83
 
securities on a forward commitment or when-issued basis. In a repurchase
agreement, the Fund buys a security subject to the right and obligation to sell
it back to the seller at a higher price. These transactions must be fully
collateralized at all times, but involve some credit risk to the Fund if the
other party defaults on its obligation and the Fund is delayed in or prevented
from liquidating the collateral. The Fund will segregate in a separate account
cash or liquid, high grade debt securities equal in value to its forward
commitments and when-issued securities. Purchasing debt securities for future
delivery or on a when-issued basis may increase the Fund's overall investment
exposure and involves a risk of loss if the value of the securities declines
before the settlement date.
 
REVERSE REPURCHASE AGREEMENTS.  A reverse repurchase agreement involves the sale
of a security by the Fund and its agreement to repurchase the instrument at a
specified time and price. The Fund will maintain a segregated account consisting
of highly liquid, marketable securities to cover its obligations under reverse
repurchase agreements with selected firms approved in advance by the Board of
Trustees. The Fund will use the proceeds to purchase other investments. Reverse
repurchase agreements are considered to be borrowings by the Fund. As an
investment practice reverse repurchase agreements may have the effect of
leveraging the Fund's assets and may be considered speculative. Leveraging may
magnify the potential for gain or loss on the portfolio securities of the Fund
and therefore increase the possibility of fluctuation in the Fund's net asset
value. The Fund will limit its investments in reverse repurchase agreements and
other borrowings to no more than 33 1/3% of its total net assets.
 
SHORT-TERM TRADING AND PORTFOLIO TURNOVER.  Short-term trading means the
purchase and subsequent sale of a security after it has been held for a
relatively brief period of time. Short-term trading may have the effect of
increasing portfolio turnover rate. Short-term trading of fixed-income
securities should not increase direct transaction costs since fixed-income
securities are normally traded on a principal basis without brokerage
commissions. The Fund does not invest for the purpose of seeking short-term
profits. The Fund's investment securities may be changed, however, without
regard to the holding period of these securities (subject to certain tax
restrictions), when the Adviser deems that this action will help achieve the
Fund's objective given a change in an issuer's operations or changes in general
market conditions. A rate of turnover of 100% would occur if the value of the
lesser of purchases and sales of investment securities for a particular year
equaled the average monthly value of investment securities owned during the year
(excluding short-term securities). A high rate of portfolio turnover (100% or
more) may make it more difficult for the Fund to qualify as a regulated
investment company under the Code. The Fund's portfolio turnover rate is set
forth in the table under "Financial Highlights."
 
MORTGAGE "DOLLAR ROLL" TRANSACTIONS.  The Fund may enter into mortgage "dollar
roll" transactions with selected banks and broker-dealers pursuant to which the
Fund sells mortgage-backed securities and simultaneously contracts to repurchase
substantially similar (same type, coupon and maturity) securities on a specified
future date. The Fund will only enter into covered rolls. A "covered roll"
 
                                       25
<PAGE>   84
 
   
is a specific type of dollar roll for which there is an offsetting cash position
or a cash equivalent security position which matures on or before the forward
settlement date of the dollar roll transaction. Covered rolls are not treated as
a borrowing or other senior security and will be excluded from the calculation
of the Fund's borrowings and other senior securities. For financial reporting
and tax purposes, the Fund treats mortgage dollar rolls as two separate
transactions; one involving the purchase of a security and a separate
transaction involving a sale. The Fund does not currently intend to enter into
mortgage dollar roll transactions that are accounted for as a financing.
    
 
OPTIONS AND FUTURES TRANSACTIONS.  The Fund may buy and sell options contracts,
financial futures contracts and options on futures contracts. Options and
futures contracts are bought and sold to manage the Fund's exposure to changing
interest rates, and security prices. Some options and futures strategies,
including selling futures, buying puts, and writing calls, tend to hedge the
Fund's investments against price fluctuations. Other strategies, including
buying futures, writing puts, and buying calls, tend to increase market
exposure. Options and futures may be combined with each other or with forward
contracts to adjust the risk and return characteristics of the overall strategy.
The Fund may invest in options and futures based on securities or indices,
including options and futures traded on foreign exchanges and options not traded
on exchanges.
 
Options and futures can be volatile investments and involve certain risks. If
the Adviser applies a hedge at an inappropriate time or judges market conditions
incorrectly, options and futures strategies may lower the Fund's return. The
Fund could also experience losses if the prices of its options and futures
positions were poorly correlated with its other investments, or if it could not
close out its positions because of an illiquid secondary market. Options and
futures do not pay interest, but may produce capital gains.
 
The Fund will not engage in a transaction in futures or options on futures for
non-hedging purposes if, immediately thereafter, the sum of initial margin
deposits and premiums required to establish speculative positions in futures
contracts and options on futures would exceed 5% of the Fund's net assets. The
loss incurred by the Fund investing in futures contracts and in writing options
on futures is potentially unlimited and may exceed the amount of any premium
received. The Fund's transactions in options and futures contracts may be
limited by the requirements of the Code or qualification as a regulated
investment company.
 
RISKS ASSOCIATED WITH OPTIONS, FUTURES AND OTHER DERIVATIVE INSTRUMENTS.  The
risks associated with the Fund's transactions in options, futures and other
derivative instruments, including mortgage-backed securities, may include some
or all of the following:
 
Market Risk.  Options and futures transactions, as well as other derivative
instruments, involve the risk that the applicable market will move against the
Fund's derivative position and that the Fund will incur a loss. For derivative
contracts other than purchased options, this loss may exceed the amount of the
initial investment made or the premium received by the Fund. Investments in
 
                                       26
<PAGE>   85
 
mortgage-backed securities are subject to the prepayment, extension, interest
rate and other market risks described above.
 
Leverage and Volatility Risk.  Derivative instruments may increase or leverage
the Fund's exposure to a particular market risk, which may increase the
volatility of the Fund's net asset value. The Fund may partially offset the
leverage inherent in derivative instruments by maintaining a segregated account
consisting of cash and liquid, high grade debt securities, by holding offsetting
portfolio securities or currency positions or by covering written options.
 
Correlation Risk.  The Fund's success in using derivative instruments to hedge
portfolio assets depends on the degree of price correlation between the
derivative instrument and the hedged asset. Imperfect correlation may be caused
by several factors, including temporary price disparities among the trading
markets for the derivative instruments, the assets underlying the derivative
instrument and the Fund's portfolio assets.
 
Credit Risk.  Over-the-counter instruments involve a risk that the issuer or
counterparty will fail to perform its contractual obligations.
 
Liquidity and Valuation Risk.  Some derivative instruments are not readily
marketable or may become illiquid under adverse market conditions. In addition,
during periods of extreme market volatility, an exchange may suspend or limit
trading in an exchange-traded derivative instrument, which may make the contract
temporarily illiquid and difficult to price. The staff of the SEC takes the
position that certain over-the-counter options are subject to the Fund's 15%
limit on illiquid investments. The Fund's ability to terminate over-the-counter
derivative instruments may depend on the cooperation of the counterparties to
these instruments. For derivative instruments that are not heavily traded, the
only source of price quotations may be the selling dealer or counterparty.

INVESTMENT OBJECTIVE AND POLICIES
 
- -------------------------------------------------------------------------------
                   THE FUND SEEKS TO PROVIDE A HIGH LEVEL OF
                   CURRENT INCOME CONSISTENT WITH
                   PRESERVATION OF CAPITAL AND MAINTENANCE OF
                   LIQUIDITY.
- -------------------------------------------------------------------------------

The investment objective of the Fund is to achieve a high level of current
income, consistent with preservation of capital and maintenance of liquidity.
The Fund seeks to achieve its investment objective by investing in debt
obligations issued or guaranteed by the U.S. Government, its agencies or
instrumentalities ("U.S. Government securities") whose dollar-weighted average
portfolio maturity or average life (under normal market conditions) is between
one and ten years. Because of the uncertainty inherent in all investments, no
assurance can be given that the Fund will achieve its investment objective. The
Fund has undertaken that it (i) will maintain an overall portfolio maturity of
not less than three years and (ii) will not alter such undertaking without first
approving a change in the name of the Fund which deletes the descriptive term
"Intermediate" from the resulting name. U.S. Government securities consist of
the following:
 
1. U.S. Treasury obligations, which differ only in their interest rates,
   maturities and times of issuance, including U.S. Treasury bills (maturity of
   one year or less), U.S. Treasury notes (maturity of one to ten years), and
   U.S. Treasury bonds (generally maturities greater than ten years); and
 
2. Obligations issued or guaranteed by the U.S. Government, its agencies or
   instrumentalities which are supported by: (i) the full faith and credit of
   the U.S. Government (e.g., securities issued by the Government National
   Mortgage Association ("GNMA")); (ii) the right of the issuer to borrow an
   amount limited to a specific line of credit from the U.S. Government (e.g.,
   securities of the Federal Home Loan Bank Board); or (iii) the credit of the
   instrumentality (e.g., bonds issued by the Federal National Mortgage
   Association ("FNMA")).
 
While, as a non-fundamental investment policy, the Fund may invest in any of the
foregoing obligations, it is currently anticipated that a substantial portion of
the Fund's assets will be invested in mortgage pass-through securities set forth
in (2) above. Mortgage-backed securities derive their value from an underlying
investment structure and accordingly are known as "derivatives." Derivatives
(such as stripped mortgage-backed securities) involve substantial risk including
higher price volatility and the possible lack of a readily available market.
Types of mortgage-backed securities include securities issued or guaranteed by
GNMA, FNMA, and the Federal Home Loan Mortgage Corporation ("FHLMC"). Although
these mortgage-backed securities are guaranteed or issued by U.S. Government
agencies or instrumentalities, FNMA and FHLMC securities are not backed by the
"full faith and credit" of the U.S. Government. In such cases, the Fund must
look principally to the agency issuing or guaranteeing the security for ultimate
payment. Mortgage pass-through securities are securities representing interest
in "pools" of mortgage loans. Monthly payments of interest and principal by the
individual borrowers on mortgages are passed through to the holders of the
securities (net of fees paid to the issuer or guarantor of the securities) as
the mortgages in the underlying mortgage pools are paid off. The average lives
of the mortgage pass-through securities are variable when issued because their
average lives depend on prepayment rates. The average life of these securities
is likely to be substantially shorter than their stated final maturity as a
result of unscheduled principal
 
                                        4
<PAGE>   91
 
prepayments. Prepayments on underlying mortgages result in a loss of anticipated
interest, and all or part of a premium, if any has been paid, and the actual
yield (or total return) to the Fund may be different than the quoted yield on
the securities. Mortgage prepayments generally increase with declining interest
rates and decrease with rising interest rates. Like other fixed income
securities, when interest rates rise the value of a mortgage pass-through
security generally will decline; however, when interest rates are declining, the
value of mortgage pass-through securities with prepayment features may not
increase as much as that of other fixed income securities. In cases where U.S.
Government support of agencies or instrumentalities is discretionary, no
assurance can be given that the U.S. Government will provide financial support,
since it is not legally obligated to do so.
 
STRIPPED MORTGAGE-BACKED SECURITIES

The Fund may acquire stripped mortgage-backed securities ("SMBS") which are
issued and guaranteed by U.S. Government agencies or instrumentalities. For
example, Class 1 and Class 2 stripped mortgage-backed securities ("SMBS
Certificates") are issued by the FNMA. Since Class 1 Certificates generally
benefit from declining interest rates and Class 2 Certificates generally benefit
from rising interest rates, these securities can provide an effective way to
stabilize portfolio value. SMBS Certificates represent beneficial interests in
principal distributions and interest distributions on certain FNMA guaranteed
mortgage pass-through certificates which represent all or part of the beneficial
interests in pools of first lien, single family (one-to-four family residential
property), fixed-rate residential mortgage loans. The original principal amount
of each SMBS Class 1 Certificate represents the amount payable over the life of
the Certificate from principal distributions on the underlying mortgage-backed
securities held by FNMA in its capacity as Trustee of the SMBS trust. Interest
distributions allocable to the SMBS Class 2 Certificates consist of interest at
the pass-through rate specified on the aggregate amount thereof which will
always be equal to the aggregate outstanding principal amount of each associated
issue of SMBS Class 1 Certificates.
 
COLLATERALIZED MORTGAGE OBLIGATIONS AND MULTI-CLASS PASS-THROUGH SECURITIES

The Fund may invest a portion of its assets in collateralized mortgage
obligations or "CMOs," which are debt obligations collateralized by mortgage
loans or mortgage pass-through securities (such collateral collectively herein
referred to as "Mortgage Assets"). Mortgage Assets underlying CMOs purchased by
the Fund must be U.S. Government securities. The Fund may also invest a portion
of its assets in multi-class pass-through securities which are issued or
guaranteed by the U.S. Government, its agencies, authorities or
instrumentalities. Unless the context indicates otherwise, all references herein
to CMOs include multi-class pass-through securities. Payments of principal and
interest on the Mortgage Assets, and any reinvestment income thereon, provide
the funds to pay debt service on the CMOs or make scheduled distributions on the
multi-class pass-through securities.
 
                                        5
<PAGE>   92
 
In a CMO, a series of bonds or certificates is usually issued in multiple
classes with different maturities. Each class of CMO, often referred to as a
"tranche," is issued at a specific fixed or floating coupon rate and has a
stated maturity or final distribution date. Principal prepayments on the
Mortgage Assets may cause the CMOs to be retired substantially earlier than
their stated maturities or final distribution dates, resulting in a loss of all
or part of the premium, if any has been paid.
 
In addition to the risks associated with prepayments previously described,
prepayment on the Mortgage Assets can be expected to accelerate during periods
of declining interest rates and thus impair the Fund's ability to reinvest the
proceeds in securities with comparable yields. In addition, the U.S. Government
guarantee as to payment of principal and interest of the Fund's U.S. Government
mortgage-backed securities, (which does not extend to the Fund's other asset-
backed securities), does not extend to the value or yield of such securities or
of the Fund's shares of beneficial interest. SMBS Certificates involve risks in
addition to those associated with regular mortgage-backed securities. A rate of
principal payments on the underlying mortgage loans slower than the rate
anticipated by an investor in calculating the initial yield to maturity on an
SMBS Certificate, which could result from stable or rising interest rates (which
would tend to reduce the market value of the Certificate), will, by delaying the
distribution of principal, reduce the yield to maturity on SMBS Class 1
Certificates (principal) purchased at a discount from their original principal
amount and increase the yield to maturity on SMBS Class 2 Certificates (income).
Payments of principal on the underlying mortgage loans at rates faster than the
rate anticipated by investors, which could result from falling interest rates or
from transfers of the underlying property, will, conversely, accelerate
distributions of principal and thereby reduce the yield to maturity on SMBS
Class 2 Certificates (income) and increase the yield to maturity on SMBS Class 1
Certificates (principal). Sufficiently high prepayment rates could result in
purchasers of SMBS Class 2 Certificates (income) not recovering the full amount
of their initial investment. Yields on SMBS Certificates will be extremely
sensitive to actual or anticipated prepayment experienced on the underlying
mortgage loans and significant fluctuations in interest rates may result in
major fluctuations in the market value of such Certificates.
 
The investment techniques and various policies the Fund may employ in seeking to
achieve its investment objective, such as lending portfolio securities,
securities transactions subject to delayed settlement, options and futures
transactions, mortgage "dollar roll" transactions, or repurchase and reverse
repurchase agreements, may involve a greater degree of risk than those inherent
in more conservative investment approaches. As a non-fundamental investment
policy, the Fund will at all times invest at least 80% of its total assets in
U.S. Government securities. This will serve to limit the Fund's investments in
these investment techniques, in the aggregate, to not more than 20% of the
Fund's total assets. The Fund will limit its investments in stripped
mortgage-backed securities to 10% of its total assets. While the Fund is
permitted to invest up to 100% of its net assets in other derivative securities,
it does not expect to invest substantially in derivative
 
                                        6
<PAGE>   93
 
securities. See "Investments, Techniques and Risk Factors" for a discussion of
these techniques and their associated risks.
 
The Fund's rate of return fluctuates, as does its net asset value per share.
These fluctuations depend largely on changes in the general level of interest
rates. An increase in interest rates will tend to reduce the market values of
securities in which the Fund invests and, therefore, the Fund's net asset value;
whereas a decline in interest rates will tend to increase their values. The Fund
will seek to reduce risks associated with changes in interest rates through its
transactions in options and futures contracts. However, this technique will not
eliminate such risks and will result in transaction costs to the Fund.

- -------------------------------------------------------------------------------
                   THE FUND FOLLOWS CERTAIN POLICIES WHICH
                   MAY HELP TO REDUCE INVESTMENT RISK.
- -------------------------------------------------------------------------------

The Fund has adopted certain investment restrictions which are enumerated in
detail in the Statement of Additional Information where they are classified as
fundamental. The Fund's investment objective and fundamental policies (such as
the policy concerning the securities in which the Fund may invest as described
above) and restrictions may not be changed without the approval of the Fund's
shareholders. The Fund's non-fundamental investment policies and restrictions,
however, may be changed by a vote of the Trustees without shareholder approval.
Notwithstanding the Fund's fundamental investment restriction prohibiting
investments in other investment companies, the Fund may, pursuant to an order
granted by the SEC, invest in other investment companies in connection with a
deferred compensation plan for the non-interested Trustees of the John Hancock
funds. There can be no assurance that the Fund will achieve its investment
objective.
 
- -------------------------------------------------------------------------------
                   BROKERS ARE CHOSEN ON BEST PRICE AND
                   EXECUTION.
- -------------------------------------------------------------------------------

The primary consideration in choosing brokerage firms to carry out the Fund's
transactions is execution at the most favorable prices, taking into account the
broker's professional ability and quality of service. Consideration may also be
given to the broker's sales of Fund shares. Pursuant to procedures determined by
the Trustees, the Fund's investment adviser, John Hancock Advisers, Inc. (the
"Adviser"), may place securities transactions with brokers affiliated with the
Adviser. The brokers include Tucker Anthony Incorporated, Sutro and Company,
Inc. and John Hancock Distributors, Inc., which are indirectly owned by the John
Hancock Mutual Life Insurance Company (the "Life Company"), which in turn
indirectly owns the Adviser.
 
 
ORGANIZATION AND MANAGEMENT OF THE FUND

- -------------------------------------------------------------------------------
                   THE BOARD OF TRUSTEES ELECTS OFFICERS AND
                   RETAINS THE INVESTMENT ADVISER WHO IS
                   RESPONSIBLE FOR THE DAY-TO-DAY OPERATIONS
                   OF THE FUND, SUBJECT TO THE BOARD OF
                   TRUSTEES' POLICIES AND SUPERVISION.
- -------------------------------------------------------------------------------

The Fund is a diversified series of the Trust, an open-end management investment
company organized as a Massachusetts business trust. The Trust has six series of
shares, one of which is the Fund. The Trust reserves the right to create and
issue a number of series of shares, or funds or classes thereof, which are
separately managed and have different investment objectives. The Trustees have
authorized the issuance of two classes of the Fund, designated Class A and 
Class B. The shares of each class represent an interest in the same portfolio of
investments of the Fund. Each class has equal rights as to voting, redemption,
dividends and liquidation. However, each class bears different distribution and
transfer agent fees and other expenses. Also, Class A and Class B shareholders
have exclusive voting rights with respect to their distribution plans. The Trust
is not required to and does 

 
 
                                        7
<PAGE>   94
not intend to hold annual meetings of shareholders, although special meetings 
may be held for such purposes as electing or removing Trustees, changing 
fundamental policies or approving a management contract. The Trust, under 
certain circumstances, will assist in shareholder communications with other 
shareholders.

- -------------------------------------------------------------------------------
                   JOHN HANCOCK ADVISERS, INC. ADVISES
                   INVESTMENT COMPANIES HAVING AN AGGREGATE
                   NET ASSET VALUE OF MORE THAN $13 BILLION.
- -------------------------------------------------------------------------------

The Adviser was organized in 1968 and is a wholly-owned indirect subsidiary of
the Life Company, a financial services company. The Adviser provides the Fund,
and other investment companies in the John Hancock group of funds, with
investment research and portfolio management services. John Hancock Funds, Inc.
("John Hancock Funds") distributes shares for all of the John Hancock mutual
funds through brokers which have arrangements with John Hancock Funds ("Selling
Brokers"). Certain Trust officers are also officers of the Adviser and John
Hancock Funds.
 
All investment decisions are made by a committee and no single person is
primarily responsible for making recommendations to the committee.
 
In order to avoid any conflict with portfolio trades for the Fund, the Adviser
and the Fund have adopted extensive restrictions on personal securities trading
by personnel of the Adviser and its affiliates. Some of these restrictions are:
preclearance for all personal trades and a ban on the purchase of initial public
offerings, as well as contributions to specified charities of profits on
securities held for less than 91 days. These restrictions are a continuation of
the basic principle that the interests of the Fund and its shareholders come
first.
 
ALTERNATIVE PURCHASE ARRANGEMENTS
 
- -------------------------------------------------------------------------------
                   AN ALTERNATIVE PURCHASE PLAN ALLOWS YOU TO
                   CHOOSE THE METHOD OF PAYMENT THAT IS BEST
                   FOR YOU.
- -------------------------------------------------------------------------------

You can purchase shares of the Fund at a price equal to their net asset value
per share plus a sales charge. At your election, this charge may be imposed
either at the time of the purchase (see "Initial Sales Charge Alternative,"
Class A shares) or on a contingent deferred basis (the "Contingent Deferred
Sales Charge Alternative," Class B shares). If you do not specify on your
account application the class of shares you are purchasing, it will be assumed
that you are investing in Class A shares.
 
- -------------------------------------------------------------------------------
                   INVESTMENTS IN CLASS A SHARES ARE SUBJECT
                   TO AN INITIAL SALES CHARGE.
- -------------------------------------------------------------------------------
 
CLASS A SHARES.  If you elect to purchase Class A shares, you will incur an
initial sales charge unless the amount of your purchase is $1 million or more.
If you purchase $1 million or more of Class A shares, you will not be subject to
an initial sales charge, but you will incur a sales charge if you redeem your
shares within one year of purchase. Class A shares are subject to ongoing
distribution and service fees at a combined annual rate of up to 0.25% of the
Fund's average daily net assets attributable to the Class A shares. Certain
purchases of Class A shares qualify for reduced initial sales charges. See
"Share Price -- Qualifying for a Reduced Sales Charge."
 
- -------------------------------------------------------------------------------
                   INVESTMENTS IN CLASS B SHARES ARE SUBJECT
                   TO A CONTINGENT DEFERRED SALES CHARGE.
- -------------------------------------------------------------------------------
 
CLASS B SHARES.  You will not incur a sales charge when you purchase Class B
shares, but the shares are subject to a sales charge if you redeem them within
six years of purchase (the "contingent deferred sales charge" or the "CDSC").
Class B shares are subject to ongoing distribution and service fees at a

annual rate of up to 1.00% of the Fund's average daily net assets attributable
to the Class B shares. Investing in Class B shares permits all of your dollars
to work from the time you make your investment, buy the higher ongoing
distribution fee will cause these shares to have higher expenses than those of
Class A shares. To the extent that any dividends are paid by the Fund, these
higher expenses will also result in lower dividends than those paid on Class A
shares. 

Class B shares are not available for full-service defined contribution plans
administered by Investor Services or the Life Company that had more than 100
eligible employees at the inception of the Fund account.
 
FACTORS TO CONSIDER IN CHOOSING AN ALTERNATIVE
 
- -------------------------------------------------------------------------------
                   YOU SHOULD CONSIDER WHICH CLASS OF SHARES
                   WOULD BE MORE BENEFICIAL TO YOU.
- -------------------------------------------------------------------------------

The alternative purchase arrangement allows you to choose the most beneficial
way to buy shares, given the amount of your purchase, the length of time you
expect to hold your shares and other circumstances. You should consider whether,
during the anticipated life of your Fund investment, the CDSC and accumulated
fees on Class B shares would be less than the initial sales charge and
accumulated fees on Class A shares purchased at the same time, and to what
extent this differential would be offset by the Class A shares' lower expenses.
To help you make this determination, the table under the caption "Expense
Information" on the inside cover page of this Prospectus shows examples of the
charges applicable to each class of shares. Class A shares will normally be more
beneficial if you qualify for reduced sales charges. See "Share
Price -- Qualifying for a Reduced Sales Charge."
 
Class A shares are subject to lower distribution fees and, accordingly, pay
correspondingly higher dividends per share, to the extent any dividends are
paid. However, because initial sales charges are deducted at the time of
purchase, you would not have all of your funds invested initially and,
therefore, would initially own fewer shares. If you do not qualify for reduced
initial sales charges and expect to maintain your investment for an extended
period of time, you might consider purchasing Class A shares. This is because
the accumulated distribution and service charges on Class B shares may exceed
the initial sales charge and accumulated distribution and service charges on
Class A shares during the life of your investment.
 
Alternatively, you might determine that it is more advantageous to purchase
Class B shares to have all of your funds invested initially. However, you will
be subject to higher distribution and service fees and, for a six-year period, a
CDSC.
 
In the case of Class A shares, the distribution expenses that John Hancock Funds
incurs in connection with the sale of the shares will be paid from the proceeds
of the initial sales charge and ongoing distribution and service fees. In the
case of Class B shares, the expenses will be paid from the proceeds of the
ongoing distribution and service fees, as well as from the CDSC incurred upon
redemption within six years of purchase. The purpose and function of the Class B
shares' CDSC and ongoing distribution and service fees are the same as those of
the Class A shares' initial sales charge and ongoing distribution and service
fees. Sales

personnel distributing the Fund's shares may receive different compensation for
selling each class of shares.
 
Dividends, if any, on Class A and Class B shares will be calculated in the same
manner, at the same time and on the same day. They also will be in the same
amount, except for differences resulting from each class bearing only its own
distribution and service fees, shareholder meeting expenses and any incremental
transfer agency costs. See "Dividends and Taxes."
 
THE FUND'S EXPENSES
For managing its investment and business affairs, the Fund pays a monthly fee to
the Adviser which is equal on an annual basis to 0.50% of the Fund's average
daily net assets. During the Fund's fiscal year ended March 31, 1995, the Fund's
former investment adviser agreed not to impose $38,507 of their advisory fee
resulting in an advisory fee paid by the Fund equal to 0.08% of average net
assets.
 
- -------------------------------------------------------------------------------
                   THE FUND PAYS DISTRIBUTION AND SERVICE
                   FEES FOR MARKETING AND SALES-RELATED
                   SHAREHOLDER SERVICING.
- -------------------------------------------------------------------------------
 
The Class A and Class B shareholders have adopted distribution plans (each a
"Plan") pursuant to Rule 12b-1 under the Investment Company Act of 1940 (the
"1940 Act"). Under these Plans, the Fund will pay distribution and service fees
at an aggregate annual rate of up to 0.25% of the Class A shares' average daily
net assets and an aggregate annual rate of 1.00% of the Class B shares' average
daily net assets. In each case, up to 0.25% for Class A and Class B shares is
for service expenses and the remaining amount is for distribution expenses. The
distribution fees will be used to reimburse John Hancock Funds for its
distribution expenses, including but not limited to: (i) initial and ongoing
sales compensation to Selling Brokers and others (including affiliates of John
Hancock Funds) engaged in the sale of Fund shares; (ii) marketing, promotional
and overhead expenses incurred in connection with the distribution of Fund
shares; (iii) unreimbursed distribution expenses under the Fund's prior
distribution plans; (iv) distribution expenses incurred by other investment
companies which sell all or substantially all of their assets to, merge with or
otherwise engage in a reorganization transaction with the Fund; and (v) with
respect to Class B shares only, interest expenses on unreimbursed distribution
expenses. The service fees will be used to compensate Selling Brokers for
providing personal and account maintenance services to shareholders.
 
In the event John Hancock Funds is not fully reimbursed for payments it makes or
expenses it incurs under the Class A Plan, these expenses will not be carried
beyond one year from the date they were incurred. Unreimbursed expenses under
the Class B Plan will be carried forward together with interest on the balance
of these unreimbursed expenses.
 
The Adviser has voluntarily and temporarily agreed to limit the Fund's aggregate
operating expenses and to reduce its advisory fee to the extent necessary to
limit the total of the advisory fee and aggregate operating expenses of the Fund
(not including transfer agent fees and fees payable by the Fund under a Rule
12b-1 plan or any other class-specific expenses) to 0.91% of the average net
assets attributable to the Class A and Class B shares, respectively.

DIVIDENDS AND TAXES

- -------------------------------------------------------------------------------
                   THE FUND GENERALLY DECLARES DIVIDENDS
                   DAILY AND DISTRIBUTES THEM MONTHLY.
- -------------------------------------------------------------------------------

DIVIDENDS.  The Fund generally declares daily and distributes monthly dividends
representing all or substantially all of its net investment income. The Fund
will distribute net realized long-term and short-term capital gains, if any, at
least annually.
 
Dividends are reinvested in additional shares of your class unless you elect the
option to receive them in cash. If you elect the cash option and the U.S. Postal
Service cannot deliver your checks, your election will be converted to the
reinvestment option. Because of the higher expenses associated with Class B
shares, any dividends on these shares will be lower than those on the Class A
shares. See "Share Price."
 
TAXATION.  Dividends from the Fund's net investment income and net short-term
capital gains are taxable to you as ordinary income and dividends from the
Fund's net long-term capital gains are taxable as long-term capital gains. These
dividends are taxable whether you take them in cash or reinvest in additional
shares. Certain dividends may be paid in January of a given year but may be
taxable as if you received them the previous December.
 
The Fund has qualified and intends to continue to qualify as a regulated
investment company under Subchapter M of the Internal Revenue Code of 1986, as
amended (the "Code"). As a regulated investment company, the Fund will not be
subject to Federal income tax on any net investment income or net realized
capital gains that are distributed to its shareholders within the time period
prescribed by the Code. When you redeem (sell) or exchange shares, you may
realize a taxable gain or loss.
 
On the account application, you must certify that the social security or other
taxpayer identification number you provide is your correct number and that you
are not subject to backup withholding of Federal income tax. If you do not
provide this information or are otherwise subject to this withholding, the Fund
may be required to withhold 31% of your dividends and the proceeds of
redemptions or exchanges.
 
In addition to Federal taxes, you may be subject to state, local or foreign
taxes with respect to your investment in and distributions from the Fund.
Non-U.S. shareholders and tax-exempt shareholders are subject to different tax
treatment not described above. A state income (and possibly local income and/or
intangible property) tax exemption is generally available to the extent the
Fund's distributions are derived from interest on (or, in the case of
intangibles taxes, the value of its assets is attributable to) certain U.S.
Government obligations, provided in some states that certain thresholds for
holdings of such obligations and/or reporting requirements are satisfied. You
should consult your tax adviser for specific tax advice.

PERFORMANCE
 
- -------------------------------------------------------------------------------
                   THE FUND MAY ADVERTISE ITS YIELD AND TOTAL
                   RETURN.
- -------------------------------------------------------------------------------

Yield reflects the Fund's rate of income on portfolio investments as a
percentage of its share price. Yield is computed by annualizing the result of
dividing the net investment income per share over a 30 day period by the maximum
offering price per share on the last day of that period. Yield is also
calculated according to accounting methods that are standardized for all stock
and bond funds. Because yield accounting methods differ from the methods used
for other accounting purposes, the Fund's yield may not equal the income paid on
shares or the income reported in the Fund's financial statements.
 
The Fund's total return shows the overall dollar or percentage change in value
of a hypothetical investment in the Fund, assuming the reinvestment of all
dividends. Cumulative total return shows the Fund's performance over a period of
time. Average annual total return shows the cumulative return divided over the
number of years included in the period. Because average annual total return
tends to smooth out variations in the Fund's performance, you should recognize
that it is not the same as actual year-to-year results.
 
Both total return and yield calculations for Class A shares generally include
the effect of paying the maximum sales charge (except as shown in "The Fund's
Financial Highlights"). Investments at a lower sales charge would result in
higher performance figures. Total return and yield calculations for Class B
shares reflect the deduction of the applicable CDSC imposed on a redemption of
shares held for the applicable period. All calculations assume that all
dividends are reinvested at net asset value on the reinvestment dates during the
periods. Total return and yield of Class A and Class B shares will be calculated
separately and, because each class is subject to different expenses, the total
return and yield may differ with respect to each class for the same period. The
relative performance of the Class A and Class B shares will be affected by a
variety of factors, including the higher operating expenses attributable to the
Class B shares, whether the Fund's investment performance is better in the
earlier or later portions of the period measured and the level of net assets of
the classes during the period. The Fund will include the total return of Class A
and Class B shares in any advertisement or promotional materials including Fund
performance data. The value of Fund shares, when redeemed, may be more or less
than their original cost. Both yield and total return are historical
calculations and are not an indication of future performance. See "Factors to
Consider in Choosing an Alternative."

SHARE PRICE
 
- -------------------------------------------------------------------------------
                   THE OFFERING PRICE OF YOUR SHARES IS THEIR
                   NET ASSET VALUE PLUS A SALES CHARGE, IF
                   APPLICABLE, WHICH WILL VARY WITH THE
                   PURCHASE ALTERNATIVE YOU CHOOSE.
- -------------------------------------------------------------------------------
 
The net asset value per share ("NAV") is the value of one share. The NAV is
calculated by dividing the net assets of each class by the number of outstanding
shares of that class. The NAV of each class can differ. Securities in the Fund's
portfolio are valued on the basis of market quotations, valuations provided by
independent pricing services or at fair value as determined in good faith
according to procedures approved by the Trustees. Short-term debt investments
maturing within 60 days are valued at amortized cost, which the Trustees have
determined approximates market value. The NAV is calculated once daily as of the
close of regular trading on the New York Stock Exchange (generally at 4:00 p.m.,
New York time) on each day that the Exchange is open.
 
Shares of the Fund are sold at the offering price based on the NAV computed
after your investment request is received in good order by John Hancock Funds.
If you buy shares of the Fund through a Selling Broker, the Selling Broker must
receive your investment before the close of regular trading on the New York
Stock

  (*) Upon notice to Selling Brokers with whom it has sales agreements, John
      Hancock Funds may reallow an amount up to the full applicable sales
      charge. A Selling Broker to whom substantially the entire sales charge is
      reallowed or who receives these incentives may be deemed to be an
      underwriter under the Securities Act of 1933. Other than distribution and
      service fees, the Fund does not bear distribution expenses.
 
 (**) No sales charge is payable at the time of purchase of Class A shares of $1
      million or more, but a CDSC may be imposed in the event of certain
      redemption transactions within one year of purchase.
 
(***) John Hancock Funds may pay a commission and the first year's service fee
      (as described in (+) below) to Selling Brokers who initiate and are
      responsible for purchases of Class A shares of $1 million or more in
      aggregate as follows: 1% on sales to $4,999,999, 0.50% on the next $5
      million and 0.25% on $10 million and over.
 
  (+) At the time of sale, John Hancock Funds pays to Selling Brokers the first
      year's service fee in advance in an amount equal to 0.25% of the net
      assets invested in the Fund at the time of the sale. Thereafter, it pays
      the service fee periodically in arrears in an amount up to 0.25% of the
      Fund's average annual net assets. Selling Brokers receive the fee as
      compensation for providing personal and account maintenance services to
      shareholders.
</TABLE>
 
Sales charges ARE NOT APPLIED to any dividends that are reinvested in additional
Class A shares of the Fund.
 
In addition, John Hancock Funds will pay certain affiliated Selling Brokers at
an annual rate of up to 0.05% of the daily net assets of accounts attributable
to these brokers.
 
Under certain circumstances described below, investors in Class A shares may be
entitled to pay reduced sales charges. See "Qualifying for a Reduced Sales
Charge."
 
CONTINGENT DEFERRED SALES CHARGE -- INVESTMENTS OF $1 MILLION OR MORE IN CLASS A
SHARES.  Purchases of $1 million or more of Class A shares will be made

<PAGE>   102
 
at net asset value with no initial sales charge, but if the shares are redeemed
within 12 months after the end of the calendar month in which the purchase was
made (the CDSC period), a CDSC will be imposed. The rate of the CDSC will depend
on the amount invested as follows:

Existing full service clients of the Life Company who were group annuity
contract holders as of September 1, 1994, and participant directed defined
contribution plans with at least 100 eligible employees at the inception of the
Fund account may purchase Class A shares with no initial sales charge. However,
if the shares are redeemed within 12 months after the end of the calendar year
in which the purchase was made, a CDSC will be imposed at the above rate.
 
The CDSC will be assessed on an amount equal to the lesser of the current market
value or the original purchase cost of the redeemed Class A shares. Accordingly,
no CDSC will be imposed on increases in account value above the initial purchase
price, including any distributions which have been reinvested in additional
shares.
 
In determining whether a CDSC applies to a redemption, the calculation will be
determined in a manner that results in the lowest possible rate being charged.
Therefore, it will be assumed that the redemption is first made from any shares
in your account that are not subject to the CDSC. The CDSC is waived on
redemptions in certain circumstances. See "Waiver of Contingent Deferred Sales
Charges" below.

                   YOU MAY QUALIFY FOR A REDUCED SALES CHARGE
                   ON YOUR INVESTMENT IN CLASS A SHARES.
- -------------------------------------------------------------------------------
 
QUALIFYING FOR A REDUCED SALES CHARGE.  If you invest more than $100,000 in
Class A shares of the Fund or a combination of funds within the John Hancock
family of funds (except money market funds), you may qualify for a reduced sales
charge on your investments in Class A shares through a LETTER OF INTENTION. You
may also be able to use the ACCUMULATION PRIVILEGE and the COMBINATION PRIVILEGE
to take advantage of the value of your previous investments in Class A shares of
the John Hancock funds in meeting the breakpoints for a reduced sales charge.
For the ACCUMULATION PRIVILEGE and COMBINATION PRIVILEGE, the applicable sales
charge will be based on the total of:
 
1. Your current purchase of Class A shares of the Fund.
 
2. The net asset value (at the close of business on the previous day) of (a) all
   Class A shares of the Fund you hold, and (b) all Class A shares of any other
   John Hancock funds you hold; and
 
3. The net asset value of all shares held by another shareholder eligible to
   combine his or her holdings with you into a single "purchase."
 
EXAMPLE:
 
If you hold Class A shares of a John Hancock fund with a net asset value of
$20,000 and, subsequently, invest $80,000 in Class A shares of the Fund, the
 
                                       16
<PAGE>   103
 
sales charge on this subsequent investment would be 3.75% and not 4.50% (the
rate that would otherwise be applicable to investments of less than $100,000.
See "Initial Sales Charge Alternative -- Class A Shares.")
 
- -------------------------------------------------------------------------------
                   CLASS A SHARES MAY BE AVAILABLE WITHOUT A
                   SALES CHARGE TO CERTAIN INDIVIDUALS AND
                   ORGANIZATIONS.
- -------------------------------------------------------------------------------

If you are in one of the following categories, you may purchase Class A shares
of the Fund without paying a sales charge:
 
- - A Trustee or officer of the Fund; a Director or officer of the Adviser and its
  affiliates or Selling Brokers; employees or sales representatives of any of
  the foregoing; retired officers, employees or Directors of any of the
  foregoing; a member of the immediate family of any of the foregoing; or any
  fund, pension, profit sharing or other benefit plan for the individuals
  described above.
 
- - Any state, county, city or any instrumentality, department, authority, or
  agency of these entities that is prohibited by applicable investment laws from
  paying a sales charge or commission when it purchases shares of any registered
  investment management company.*
 
- - A bank, trust company, credit union, savings institution or other type of
  depository institution, its trust departments or common trust funds if it is
  purchasing $1 million or more for non-discretionary customers or accounts.*
 
- - A broker, dealer or registered investment adviser that has entered into an
  agreement with John Hancock Funds providing specifically for the use of Fund
  shares in fee-based investment products made available to its clients.
 
- - A former participant in an employee benefit plan with John Hancock Funds, when
  he/she withdraws from his/her plan and transfers any or all of his/her plan
  distributions directly to the Fund.
- ---------------
* For investments made under these provisions, John Hancock Funds may make a
  payment out of its own resources to the Selling Broker in an amount not to
  exceed 0.25% of the amount invested.
 
Class A shares of the Fund may be purchased without an initial sales charge in
connection with certain liquidation, merger or acquisition transactions
involving other investment companies or personal holding companies.
 
CONTINGENT DEFERRED SALES CHARGE ALTERNATIVE -- CLASS B SHARES.  Class B shares
are offered at net asset value per share without a sales charge so that your
entire initial investment will go to work at the time of purchase. However,
Class B shares redeemed within six years of purchase will be subject to a CDSC
at the rates set forth below. This charge will be assessed on an amount equal to
the lesser of the current market value or the original purchase cost of the
shares being redeemed. Accordingly, you will not be assessed a CDSC on increases
in account value above the initial purchase price, including shares derived from
dividend reinvestment.
 
In determining whether a CDSC applies to a redemption, the calculation will be
determined in a manner that results in the lowest possible rate being charged.
It will be assumed that your redemption comes first from shares you have held
beyond the six-year CDSC redemption period or those you acquired through
 
                                       17
<PAGE>   104
 
reinvestment of dividends, and next from the shares you have held the longest
during the six-year period. The CDSC is waived on redemptions in certain
circumstances. See the discussion "Waiver of Contingent Deferred Sales Charges"
below.
 
<TABLE>

EXAMPLE:
 
You have purchased 100 shares at $10 per share. The second year after your
purchase, your investment's net asset value per share has increased by $2 to
$12, and you have gained 10 additional shares through dividend reinvestment. If
you redeem 50 shares at this time, your CDSC will be calculated as follows:
 
<S>                                                                         <C>
- - Proceeds of 50 shares redeemed at $12 per share                           $  600
- - Minus proceeds of 10 shares not subject to CDSC because they were
  acquired through dividend reinvestment (10 X $12)                           -120
- - Minus appreciation on remaining shares, also not subject to CDSC 
  (40 X $2)                                                                   - 80
                                                                            ------
- - Amount subject to CDSC                                                    $  400
</TABLE>
 
Proceeds from the CDSC are paid to John Hancock Funds. John Hancock Funds uses
part of them to defray its expenses related to providing the Fund with
distribution services connected to the sale of Class B shares, such as
compensating Selling Brokers for selling these shares. The combination of the
CDSC and the distribution and service fees makes it possible for the Fund to
sell Class B shares without deducting a sales charge at the time of the
purchase.
 
The amount of the CDSC, if any, will vary depending on the number of years from
the time you purchase your Class B shares until the time you redeem them. Solely
for the purposes of determining this holding period, any payments you make
during the month will be aggregated and deemed to have been made on the last day
of the month.

A commission equal to 3.75% of the amount invested and a first year's service
fee equal to 0.25% of the amount invested are paid to Selling Brokers. The
initial service fee is paid in advance at the time of sale for the provision of
personal and account maintenance services to shareholders during the twelve
months following the sale, and thereafter the service fee is paid in arrears.

                   UNDER CERTAIN CIRCUMSTANCES, THE CDSC ON CLASS B AND
                   CERTAIN CLASS A SHARE REDEMPTIONS WILL BE WAIVED.
- -------------------------------------------------------------------------------
 
WAIVER OF CONTINGENT DEFERRED SALES CHARGES.  The CDSC will be waived on
redemptions of Class B shares and of Class A shares that are subject to a CDSC,
unless indicated otherwise, in these circumstances:
 
- - Redemptions of Class B shares made under a Systematic Withdrawal Plan (see
  "How to Redeem Shares"), as long as your annual redemptions do not exceed 10%
  of your account value at the time you establish your Systematic Withdrawal
  Plan and 10% of the value of your subsequent investments (less redemptions) in
  that account at the time you notify Investor Services. This waiver does not
  apply to Systematic Withdrawal Plan redemptions of Class A shares that are
  subject to a CDSC.
 
- - Redemptions made to effect distributions from an Individual Retirement Account
  either before or after age 59 1/2, as long as the distributions are based on
  the life expectancy or the joint-and-last survivor life expectancy of you and
  your beneficiary. These distributions must be free from penalty under the
  Code.
 
- - Redemptions made to effect mandatory distributions under the Code after age
  70 1/2 from a tax-deferred retirement plan.
 
- - Redemptions made to effect distributions to participants or beneficiaries from
  certain employer-sponsored retirement plans including those qualified under
  Section 401(a) of the Code, custodial accounts under Section 403(b)(7) of the
  Code and deferred compensation plans under Section 457 of the Code. The waiver
  also applies to certain returns of excess contributions made to these plans.
  In all cases, the distributions must be free from penalty under the Code.
 
- - Redemptions due to death or disability.
 
- - Redemptions made under the Reinvestment Privilege, as described in "Additional
  Services and Programs" of this Prospectus.
 
- - Redemptions made pursuant to the Fund's right to liquidate your account if you
  have less than $100 invested in the Fund.
 
- - Redemptions made in connection with certain liquidation, merger or acquisition
  transactions involving other investment companies or personal holding
  companies.
 
- - Redemptions from certain IRA and retirement plans that purchased shares prior
  to October 1, 1992.
 
If you qualify for a CDSC waiver under one of these situations, you must notify
Investor Services either directly or through your Selling Broker at the time you
make your redemption. The waiver will be granted once Investor Services has
confirmed that you are entitled to the waiver.
 
CONVERSION OF CLASS B SHARES.  Your Class B shares and an appropriate portion of
reinvested dividends on those shares will be converted into Class A shares
automatically. This will occur no later than the month following eight years
after the shares were purchased, and will result in lower annual distribution
fees. If you exchanged Class B shares into the Fund from another John Hancock
fund, the
 
                                       19
<PAGE>   106
 
calculation will be based on the time you purchased the shares in the original
fund. The Fund has been advised that the conversion of Class B shares to Class A
shares should not be taxable for Federal income tax purposes and should not
change a shareholder's tax basis or tax holding period for the converted shares.
 
HOW TO REDEEM SHARES
 
- -------------------------------------------------------------------------------
                   TO ASSURE ACCEPTANCE OF YOUR REDEMPTION
                   REQUEST, PLEASE FOLLOW THESE PROCEDURES.
- -------------------------------------------------------------------------------

You may redeem all or a portion of your shares on any business day. Your shares
will be redeemed at the next NAV calculated after your redemption request is
received in good order by Investor Services, less any applicable CDSC. The Fund
may hold payment until it is reasonably satisfied that investments recently made
by check or Invest-by-Phone have been collected (which may take up to 10
calendar days).
 
Once your shares are redeemed, the Fund generally sends you payment on the next
business day. When you redeem your shares, you may realize a taxable gain or
loss depending usually on the difference between what you paid for them and what
you receive for them, subject to certain tax rules. Under unusual circumstances,
the Fund may suspend redemptions or postpone payment for up to seven days or
longer, as permitted by Federal securities laws.

    BY TELEPHONE         All Fund shareholders are automatically eligible for the
                         telephone redemption privilege. Call 1-800-225-5291, from
                         8:00 A.M. to 4:00 P.M. (New York time), Monday through
                         Friday, excluding days on which the Exchange is closed.
                         Investor Services employs the following procedures to
                         confirm that instructions received by telephone are
                         genuine. Your name, the account number, taxpayer
                         identification number applicable to the account and other
                         relevant information may be requested. In addition,
                         telephone instructions are recorded.

                         You may redeem up to $100,000 by telephone, but the address
                         on the account must not have changed for the last thirty
                         days. A check will be mailed to the exact name(s) and
                         address shown on the account.

                         If reasonable procedures, such as those described above,
                         are not followed, the Fund may be liable for any loss due
                         to unauthorized or fraudulent telephone instructions. In
                         all other cases, neither the Fund nor Investor Services
                         will be liable for any loss or expense for acting upon
                         telephone instructions made in accordance with the
                         telephone transaction procedures mentioned above.
                         Telephone redemption is not available for IRAs or other
                         tax-qualified retirement plans or shares of the Fund that
                         are in certificated form.

                         During periods of extreme economic conditions or market
                         changes, telephone requests may be difficult to implement
                         due to a large volume of calls. During these times, you
                         should consider placing redemption requests in writing or
                         use EASI-Line. EASI-Line's telephone number is
                         1-800-338-8080.

                         service. Redemptions of less than $1,000 will be sent by

                   WHO MAY GUARANTEE YOUR SIGNATURE.
- -------------------------------------------------------------------------------

    A signature guarantee is a widely accepted way to protect you and the Fund by
    verifying the signature on your request. It may not be provided by a notary
    public. If the net asset value of the shares redeemed is $100,000 or less, John
    Hancock Funds may guarantee the signature. The following institutions may
    provide you with a signature guarantee, provided that the institution meets
    credit standards established by Investor Services: (i) a bank; (ii) a securities
    broker or dealer, including a government or municipal securities broker or
    dealer, that is a member of a clearing corporation or meets certain net capital
    requirements; (iii) a credit union having authority to issue signature
    guarantees; (iv) a savings and loan association, a building and loan
    association, a cooperative bank, a federal savings bank or association; or (v) a
    national securities exchange, a registered securities exchange or a clearing

                   ADDITIONAL INFORMATION ABOUT REDEMPTIONS.
- -------------------------------------------------------------------------------

- ---------------------------------------------------------------------------------
    THROUGH YOUR BROKER.  Your broker may be able to initiate the redemption.
    Contact your broker for instructions.
 
- ---------------------------------------------------------------------------------
    If you have certificates for your shares, you must submit them with your stock
    power or a letter of instructions. Unless you specify to the contrary, any
    outstanding Class A shares will be redeemed before Class B shares. You may not
    redeem certificated shares by telephone.

    Due to the proportionately high cost of maintaining small accounts, the Fund
    reserves the right to redeem at net asset value all shares in an account which
    holds less than $100 (except accounts under retirement plans) and to mail the
    proceeds to the shareholder, or the transfer agent may impose an annual fee of
    $10.00. No account will be involuntarily redeemed or additional fee imposed, if
    the value of the account is in excess of the Fund's minimum initial investment
    or if the value of the account falls below the required minimum as a result of
    market action. No CDSC will be imposed on involuntary redemptions of shares.

    Shareholders will be notified before these redemptions are to be made or this
    fee is imposed and will have 30 days to purchase additional shares to bring
    their account balance up to the required minimum. Unless the number of shares
    acquired by further purchases and dividend reinvestments, if any, exceeds the
    number of shares redeemed, repeated redemptions from a smaller account may
    eventually trigger this policy.

ADDITIONAL SERVICES AND PROGRAMS
 
EXCHANGE PRIVILEGE

- -------------------------------------------------------------------------------
                   YOU MAY EXCHANGE SHARES OF THE FUND ONLY
                   FOR SHARES OF THE SAME CLASS OF ANOTHER
                   JOHN HANCOCK FUND.
- -------------------------------------------------------------------------------
 
If your investment objective changes, or if you wish to achieve further
diversification, John Hancock offers other funds with a wide range of investment
goals. Contact your registered representative or Selling Broker and request a
prospectus for the John Hancock funds that interest you. Read the prospectus
carefully before exchanging your shares. You can exchange shares of each class
of the Fund only for shares of the same class of another John Hancock fund. For
this purpose, John Hancock funds with only one class of shares will be treated
as Class A, whether or not they have been so designated.
 
Exchanges between funds with shares that are not subject to a CDSC are based on
their respective net asset values. No sales charge or transaction charge is
imposed. Class B shares of the Fund that are subject to a CDSC may be exchanged
into Class B shares of another John Hancock fund without incurring the CDSC;
however, these shares will be subject to the CDSC schedule of the shares
acquired (except that exchanges into John Hancock Short-Term Strategic Income
Fund, John Hancock Limited-Term Government Fund and John Hancock Adjustable U.S.
Government Trust will be subject to the initial fund's CDSC). For purposes of
computing the CDSC payable upon redemption of shares acquired in an exchange,
the holding period of the original shares is added to the holding period of the
shares acquired in an exchange. However, if you exchange Class B shares
purchased prior to January 1, 1994 for Class B shares of any other John Hancock
fund, you will be subject to the CDSC schedule in effect on your initial
purchase date.
 
You may exchange Class B shares of the Fund into shares of a John Hancock money
market fund at net asset value. However, you will continue to be subject to the
same CDSC upon redemption.
 
                                       22
<PAGE>   109
 
The Fund reserves the right to require you to keep previously exchanged shares
(and reinvested dividends) in the Fund for 90 days before you are permitted to
execute a new exchange. The Fund may also terminate or alter the terms of the
exchange privilege, upon 60 days' notice to shareholders.
 
An exchange of shares is treated as a redemption of shares of one fund and the
purchase of shares in another for Federal income tax purposes. An exchange may
result in a taxable gain or loss.
 
When you make an exchange, your account registration in both the existing and
new account must be identical. The exchange privilege is available only in
states where the exchange can be made legally.
 
Under exchange agreements with John Hancock Funds, certain dealers, brokers and
investment advisers may exchange their clients' Fund shares, subject to the
terms of those agreements and John Hancock Funds' right to reject or suspend
those exchanges at any time. Because of the restrictions and procedures under
those agreements, the exchanges may be subject to timing limitations and other
restrictions that do not apply to exchanges requested by shareholders directly,
as described above.
 
Because Fund performance and shareholders can be hurt by excessive trading, the
Fund reserves the right to terminate the exchange privilege for any person or
group that, in John Hancock Funds' judgment, is involved in a pattern of
exchanges that coincide with a "market timing" strategy that may disrupt the
Fund's ability to invest effectively according to its investment objective and
policies, or might otherwise affect the Fund and its shareholders adversely. The
Fund may also temporarily or permanently terminate the exchange privilege for
any person who makes seven or more exchanges out of the Fund per calendar year.
Accounts under common control or ownership will be aggregated for this purpose.
Although the Fund will attempt to give you prior notice whenever it is
reasonably able to do so, it may impose these restrictions at any time.
 
BY TELEPHONE
 
1. When you complete the application for your initial purchase of Fund shares,
   you automatically authorize exchanges by telephone unless you check the box
   indicating that you do not wish to authorize telephone exchanges.
 
2. Call 1-800-225-5291. Have the account number of your current fund and the
   exact name in which it is registered available to give to the telephone

REINVESTMENT PRIVILEGE
 
- -------------------------------------------------------------------------------
                   IF YOU REDEEM SHARES OF THE FUND, YOU MAY
                   BE ABLE TO REINVEST ALL OR PART OF THE
                   PROCEEDS IN THE FUND OR ANOTHER JOHN
                   HANCOCK FUND WITHOUT PAYING AN ADDITIONAL
                   SALES CHARGE.
- -------------------------------------------------------------------------------
 
1. You will not be subject to a sales charge on Class A shares reinvested in
   shares of any John Hancock fund that is otherwise subject to a sales charge
   as long as you reinvest within 120 days from the redemption date. If you paid
   a CDSC upon a redemption, you may reinvest at net asset value in the same
   class of shares from which you redeemed within 120 days. Your account will be
   credited with the amount of the CDSC previously charged, and the reinvested
   shares will continue to be subject to a CDSC. For purposes of computing the
   CDSC payable upon a subsequent redemption, the holding period of the shares
   acquired through reinvestment will include the holding period of the redeemed
   shares.
 
2. Any portion of your redemption may be reinvested in Fund shares or in shares
   of any of the other John Hancock funds, subject to the minimum investment
   limit of that fund.
 
3. To reinvest, you must notify Investor Services in writing. Include the Fund's
   name, the account number and class from which your shares were originally
   redeemed.
 
SYSTEMATIC WITHDRAWAL PLAN
 
- -------------------------------------------------------------------------------
                   YOU CAN PAY ROUTINE BILLS FROM YOUR
                   ACCOUNT, OR MAKE PERIODIC DISBURSEMENTS OF
                   FUNDS FROM YOUR RETIREMENT ACCOUNT TO
                   COMPLY WITH IRS REGULATIONS.
- -------------------------------------------------------------------------------
 
1. You can elect the Systematic Withdrawal Plan at any time by completing the
   Account Privileges Application which is attached to this Prospectus. You can
   also obtain this application by calling your registered representative or by
   calling 1-800-225-5291.
 
2. To be eligible, you must have at least $5,000 in your account.
 
3. Payments from your account can be made monthly, quarterly, semi-annually or
   annually or on a selected monthly basis to yourself or any other designated
   payee.
 
                                       24
<PAGE>   111
 
4. There is no limit on the number of payees you may authorize, but all payments
   must be made at the same time or intervals.
 
5. It is not advantageous to maintain a Systematic Withdrawal Plan concurrently
   with purchases of additional Class A or Class B shares, because you may be
   subject to initial sales charges on your purchases of Class A shares or to a
   CDSC on your redemptions of Class B shares. In addition, your redemptions are
   taxable events.
 
6. Redemptions will be discontinued if the U.S. Postal Service cannot deliver
   your checks or if deposits to a bank account are returned for any reason.

MONTHLY AUTOMATIC ACCUMULATION PROGRAM (MAAP)

- -------------------------------------------------------------------------------
                   YOU CAN MAKE AUTOMATIC INVESTMENTS AND
                   SIMPLIFY YOUR INVESTING.
- -------------------------------------------------------------------------------

1. You can authorize an investment to be automatically withdrawn each month from
   your bank for investment in Fund shares under the "Automatic Investing" and
   "Bank Information" sections of the Account Privileges Application.
 
2. You can also authorize automatic investment through payroll deduction by
   completing the "Direct Deposit Investing" section of the Account Privileges
   Application.
 
3. You can terminate your Monthly Automatic Accumulation Program plan at any
   time.
 
4. There is no charge to you for this program, and there is no cost to the Fund.

INVESTMENTS, TECHNIQUES AND RISK FACTORS
 
Unless otherwise specified, each of the Fund's investment practices described in
this section and in the Statement of Additional Information is deemed to be a
fundamental policy and may not be changed without shareholder approval.
 
LENDING OF SECURITIES AND REPURCHASE AGREEMENTS.  For the purpose of realizing
additional income, the Fund may lend, to broker-dealers or to federally insured
banks or savings and loans, portfolio securities amounting to not more than
33 1/3% of its total assets taken at current value. The Fund may also enter into
repurchase agreements with registered brokers or dealers or with federally
insured banks or savings and loans which are deemed to be creditworthy by the
Adviser.
 
These transactions must be fully collateralized at all times. The Fund may
reinvest any cash collateral in short-term highly liquid debt securities.
However, these transactions may involve some credit risk to the Fund if the
other party should default on its obligation and the Fund is delayed in or
prevented from recovering the collateral. Securities loaned by the Fund will
remain subject to fluctuations of market value.
 
In a repurchase agreement, the Fund buys a security subject to the right and
obligation to sell it back to the issuer at the same price plus accrued
interest. The Fund may enter into repurchase agreements only with respect to
U.S. Government securities with maturities of three and one half years or less.
The Fund will not invest in a repurchase agreement maturing in more than seven
(7) days, if such investment, together with any other illiquid securities held
by the Fund (including restricted securities), would exceed 10% of the Fund's
total assets.
 
SHORT-TERM TRADING AND PORTFOLIO TURNOVER.  Short-term trading means the
purchase and subsequent sale of a security after it has been held for a
relatively brief period of time. Short-term trading may have the effect of
increasing portfolio turnover rate. Short-term trading of fixed-income
securities should not increase direct transaction costs since fixed-income
securities are normally traded on a principal basis without brokerage
commissions. The Fund does not intend to invest for the purpose of seeking
short-term profits. The Fund's portfolio securities may be changed, however,
without regard to the holding period of these securities (subject to certain tax
restrictions), when the Adviser deems that this action will help achieve the
Fund's objective given a change in an issuer's operations or changes in general
market conditions. The Fund's portfolio turnover rate is set forth in the table
under the caption "Financial Highlights."
 
ILLIQUID AND RESTRICTED SECURITIES.  The Fund may invest up to 10% of its total
assets in illiquid investments, which include repurchase agreements maturing in
more than seven days, certain over-the-counter options, certain stripped
mortgage-backed securities, certain restricted securities and securities that
are not readily marketable.
 
SECURITIES TRANSACTIONS SUBJECT TO DELAYED SETTLEMENT.  The Fund may from time
to time commit to purchase securities for which the normal settlement date
occurs later than the settlement date which is normal for U.S. Treasury
obligations.
 
                                       26
<PAGE>   113
 
In no event, however, will the settlement date occur later than the 29th day
after the trade date. The payment and interest rate received on such securities
are fixed at the time the buyer enters into the commitment. Although the Fund
will only enter into commitments to purchase such securities with the intention
of actually acquiring the securities, the Fund may sell these securities before
the settlement date. Such securities can involve a risk that the yields
available in the market when delivery takes place may be higher than those
obtained in the transaction itself. It is not expected that at any one time more
than 10% of the Fund's assets would be so invested.
 
WHEN-ISSUED SECURITIES.  The Fund may purchase securities on a forward or
"when-issued" basis. When the Fund engages in when-issued transactions, it
relies on the seller or the buyer, as the case may be, to consummate the
transaction. Failure to consummate the transaction may result in the Fund's
losing the opportunity to obtain an advantageous price and yield. Although the
Fund is not limited to the amount of government securities for which it has such
commitments, it is expected that under normal circumstances not more than 10% of
the Fund's total assets will be committed to such purchases.
 
MORTGAGE "DOLLAR ROLL" TRANSACTIONS.  The Fund may enter into mortgage "dollar
roll" transactions with selected banks and broker-dealers pursuant to which the
Fund sells mortgage-backed securities and simultaneously contracts to repurchase
substantially similar (same type, coupon and maturity) securities on a specified
future date. The Fund will only enter into covered rolls. A "covered roll" is a
specific type of dollar roll for which there is an offsetting cash position or a
cash equivalent security position which matures on or before the forward
settlement date of the dollar roll transaction.
 
REVERSE REPURCHASE AGREEMENTS.  The Fund may enter into reverse repurchase
agreements which involve the sale of a security by the Fund to a bank or
securities firm and its agreement to repurchase the instrument at a specified
time and price plus an agreed amount of interest. The Fund will use the proceeds
to purchase other investments. Reverse repurchase agreements are considered to
be borrowings by the Fund and as an investment practice may be considered
speculative.
 
Thus, the Fund will enter into a reverse repurchase agreement only when the
Adviser determines that the interest income to be earned from the investment of
the proceeds is greater than the interest expense of the transaction. To
minimize various risks associated with reverse repurchase agreements, the Fund
will establish and maintain with the Custodian a separate account consisting of
cash or liquid, high grade debt securities in an amount at least equal to the
repurchase prices of the securities (plus any accrued interest thereon) under
such agreements. In addition, the Fund's investment restrictions provide that
the Fund may not enter into reverse repurchase agreements exceeding in the
aggregate 33 1/3% of the value of its total net assets (including for this
purpose other borrowings of the Fund). The Fund will enter into reverse
repurchase agreements only with selected registered broker/dealers or with
federally insured banks or savings and loan associations which are approved in
advance as being creditworthy by the Trustees.
 
                                       27
<PAGE>   114
 
Under procedures established by the Trustees, the Adviser will monitor the
creditworthiness of the firms involved.
 
INTEREST RATE FUTURES CONTRACTS AND RELATED OPTIONS.  The Fund may purchase and
sell interest rate futures contracts and purchase put and call options thereon
only as a hedge against changes in the general level of interest rates in
accordance with strategies more specifically described below.
 
In addition, the Fund may purchase call options and put options on futures
contracts which are traded on a securities exchange or a Board of Trade and
enter into closing transactions with respect to such options to terminate an
existing position. A call option on a futures contract gives the holder the
right to buy and a put option on a future contract gives the holder the right to
sell the underlying futures contract at a specific price (the exercise price)
until the option expires (the expiration date). The price of a call or put
option is called a premium. The writer of an option on a futures contract is
required to deposit initial and variation margin pursuant to requirements
similar to those applicable to futures contracts. Premiums received from the
writing of an option will be included in initial margin. A position in an option
may be terminated by the purchaser prior to expiration by effecting a closing
sale transaction which is the sale of an option of the same series (i.e., the
same exercise price and expiration date) as the option previously purchased. The
premium received by the holder on the closing transaction may be more or less
than the premium paid for the option, resulting in a gain or loss on the
transaction.
 
The Fund may hedge up to the full value of its portfolio through the use of
options on futures and the sale of futures; provided, however, that the Fund may
not sell futures contracts or purchase or sell related options if immediately
thereafter the sum of the amount of margin deposits on the Fund's existing
futures and related options positions and the amount of premiums paid for
related options (measured at the time of investment) would exceed 5% of the
Fund's net assets.
 
When the Fund purchases a futures contract or a call option on a futures
contract, an amount of cash or U.S. Government securities equal to the market
value of the futures contract will be deposited in a segregated account with the
Fund's custodian to collateralize the position. See "Derivative Securities and
Asset-Backed Securities" above for a discussion of the risks associated with
futures and related options.
 
The Trustees may authorize procedures, including numerical limitations, with
regard to such transactions in furtherance of the Fund's investment objective.
Such procedures are not fundamental and may be changed by the Trustees without
the vote of the Fund's shareholders.
 
INDEXED SECURITIES.  The Fund may invest in indexed securities. The interest
rate or, in some cases, the principal payable at the maturity of an indexed
security may change positively or inversely in relation to one or more interest
rates, financial indices or other financial indicators ("reference prices"). An
indexed security may be leveraged to the extent that the magnitude of any change
in the interest rate or principal payable on an indexed security is a multiple
of the change in the reference
 
                                       28
<PAGE>   115
 
price. Thus, indexed securities may decline in value due to adverse market
changes in reference prices.
 
The indexed securities purchased by the Fund may include interest only ("IO")
and principal only ("PO") securities, floating rate securities linked to the
Cost of Funds Index ("COFI floaters"), other "lagging rate" floating rate
securities, floating rate securities that are subject to a maximum interest rate
("capped floaters"), leveraged floating rate securities ("super floaters"),
leveraged inverse floating rate securities ("inverse floaters"), dual index
floaters and range floaters.
 
RISKS OF MORTGAGE-BACKED AND INDEXED SECURITIES.  Different types of derivative
debt securities are subject to different combinations of prepayment, extension,
interest rate and/or other market risks. Conventional mortgage pass-through
securities and sequential pay CMOs are subject to all of these risks, but are
typically not leveraged. Planned amortization class ("PACs") and target
amortization class ("TACs") and other senior classes of sequential and parallel
pay CMOs involve less exposure to prepayment, extension and interest rate risk
than other mortgage-backed securities, provided that prepayment rates remain
within expected prepayment ranges or "collars."
 
The risk of early prepayments is the primary risk associated with mortgage IOs,
super floaters and other leveraged floating rate mortgage-backed securities. The
primary risks associated with COFI floaters, other "lagging rate" floaters,
capped floaters, inverse floaters, POs and leveraged inverse IOs are the
potential extension of average life and/or depreciation due to rising interest
rates. The residual classes of CMOs are subject to both prepayment and extension
risk.
 
Other types of floating rate derivative debt securities present more complex
types of interest rate risks. For example, range floaters are subject to the
risk that the coupon will be reduced to below market rates if a designated
interest rate floats outside of a specified interest rate band or collar. Dual
index or yield curve floaters are subject to depreciation in the event of an
unfavorable change in the spread between two designated interest rates.
 
RISKS ASSOCIATED WITH OPTIONS, FUTURES AND OTHER DERIVATIVE INSTRUMENTS.  The
risks associated with the Fund's transactions in options, futures and other
derivative instruments may include some or all of the following:
 
Market Risk.  Options and futures transactions, as well as other derivative
instruments, involve the risk that the applicable market will move against the
Fund's derivative position and that the Fund will incur a loss. For derivative
contracts other than purchased options, this loss may exceed the amount of the
initial investment made or the premium received by the Fund. Investments in
mortgage-backed and indexed securities are subject to the prepayment, extension,
interest rate and other market risks described above.
 
Leverage and Volatility Risk.  Derivative instruments may increase or leverage
the Fund's exposure to a particular market risk, which may increase the
volatility of the Fund's net asset value. The Fund may partially offset the
leverage inherent in derivative instruments by maintaining a segregated account
consisting of cash and
 
                                       29
<PAGE>   116
 
liquid, high grade debt securities, by holding offsetting portfolio securities
or currency positions or by covering written options.
 
Correlation Risk.  A Fund's success in using derivative instruments to hedge
portfolio assets depends on the degree of price correlation between the
derivative instrument and the hedged asset. Imperfect correlation may be caused
by several factors, including temporary price disparities among the trading
markets for the derivative instruments, the assets underlying the derivative
instrument and the Fund's portfolio assets.
 
Credit Risk.  Over-the-counter instruments involve a risk that the issuer or
counterparty will fail to perform its contractual obligations.
 
Liquidity and Valuation Risk.  Some derivative instruments are not readily
marketable or may become illiquid under adverse market conditions. In addition,
during periods of extreme market volatility, an exchange may suspend or limit
trading in an exchange-traded derivative instrument, which may make the contract
temporarily illiquid and difficult to price. The staff of the SEC takes the
position that certain over-the-counter options are subject to the Fund's 10%
limit on illiquid investments. The Fund's ability to terminate over-the-counter
derivative instruments may depend on the cooperation of the counterparties to
these instruments. For derivative instruments that are not heavily traded, the
only source of price quotations may be the selling dealer or counterparty.
 
LEVERAGE.  The use of mortgage dollar rolls and reverse repurchase agreements
involves leverage. Leverage allows any investment gains made with the additional
monies received (in excess of the costs of the mortgage dollar roll or reverse
repurchase agreement) to increase the net asset value of the Fund's shares
faster than would otherwise be the case. On the other hand, if the additional
monies received are invested in ways that do not fully recover the costs of such
transactions to the Fund, the net asset value of the Fund would fall faster than
would otherwise be the case.

ORGANIZATION OF THE TRUST

         The Trust is an open-end management investment company organized as a
Massachusetts business trust under a Declaration of Trust dated December 12,
1984.  The Trust currently has six series, including the Funds.  Prior to
December 22, 1994, the Trust was called Transamerica Bond Fund and the Funds
were called Transamerica U.S. Government Trust and Transamerica Intermediate
Government Trust.

         The Fund is managed by John Hancock Advisers, Inc. (the "Adviser"), a
wholly-owned indirect subsidiary of John Hancock Mutual Life Insurance Company
(the "Life Company"), chartered in 1862 with national headquarters at John
Hancock Place, Boston, Massachusetts.  John Hancock Funds, Inc. ("John Hancock
Funds") acts as principal distributor of the shares of the Fund.

INVESTMENT OBJECTIVE AND POLICIES

         JOHN HANCOCK U.S. GOVERNMENT TRUST:  The investment objective of U.S.
Government Fund is to earn a high level of current income consistent with
safety of principal by investing in debt obligations issued or guaranteed by
the U.S. Government, its agencies or instrumentalities, including certificates
of the Government National Mortgage Association and U.S. Treasury obligations.
In order to hedge against changes in interest rates, U.S. Government Fund may
purchase put and call options and sell interest rate futures contracts and call
options on such contracts.  Investments of U.S. Government Fund are limited to
those which a federally chartered savings and loan association may, without
limitation as to percentage of assets, invest in, sell, redeem, hold or
otherwise deal with.

         JOHN HANCOCK INTERMEDIATE GOVERNMENT TRUS:  The investment objective
of Intermediate Government Fund is to earn a high level of current income,
consistent with the preservation of capital and maintenance of liquidity.
Intermediate Government Fund invests in debt obligations issued or guaranteed
by the U.S. Government, its agencies or instrumentalities ("U.S. Government
Securities") having an average dollar weighted maturity of between one and ten
years.

         Mortgages backing the securities purchased by the Funds include not
only conventional 30-year fixed rate mortgages but also graduated payment
mortgages and 15-year mortgages.  All of these mortgages can be used to create
pass through securities.

         GNMA CERTIFICATES.  Certificates of the Government National Mortgage
Association ("GNMA") are mortgage-backed securities, which evidence an
undivided interest in a pool of mortgage loans.  GNMA Certificates differ from
bonds in that principal is paid back monthly by the borrower over the term of
the loan rather than returned in a lump sum at maturity.  GNMA Certificates
entitle the holder to receive a share of all interest and principal prepayments
paid and owed on the mortgage pool, net of fees paid to the "issuer" and GNMA,
regardless of whether or





                                       3
<PAGE>   122
not the mortgagor actually makes the payment.  The National Housing Act
authorizes GNMA to guarantee the timely payment of principal and interest on
securities backed by a pool of mortgages insured by the Federal Housing
Administration ("FHA") or the Farmer's Home Administration ("FHMA") or
guaranteed by the Veterans Administration ("VA").  The GNMA guarantee is backed
by the full faith and credit of the United States.  The GNMA is also empowered
to borrow without limitation from the U.S. Treasury if necessary to make any
payments required under its guarantee.

         FNMA SECURITIES.  Established in 1938 to create a secondary market in
mortgages, the Federal National Mortgage Association ("FNMA") is a
government-sponsored corporation owned entirely by private stockholders that
purchases residential mortgages from a list of approved seller/servicers.  FNMA
issues guaranteed mortgage pass-through certificates ("FNMA Certificates").
FNMA Certificates resemble GNMA Certificates in that each FNMA Certificate
represents a pro rata share of all interest and principal payments made and
owed on the underlying pool.  FNMA guarantees timely payment of interest on
FNMA Certificates and the stated principal amount.

         FHLMC SECURITIES.  The Federal Home Loan Mortgage Corporation
("FHLMC") was created in 1970 through enactment of Title III of the Emergency
Home Finance Act of 1970.  Its purpose is to promote development of a
nationwide secondary market in conventional residential mortgages.  FHLMC
presently issues two types of mortgage pass-through securities,  mortgage
participation certificates ("PCs") and guaranteed mortgage certificates
("GMCs").  PCs resemble GNMA Certificates in that each PC represents a pro rata
share of all interest and principal payments made and owed on the underlying
pool.  The FHLMC guarantees timely monthly payment of interest on PCs and the
stated principal amount.

CERTAIN INVESTMENT PRACTICES

         LENDING OF PORTFOLIO SECURITIES.  In order to generate additional
income, a Fund may, from time to time, lend securities from its portfolios to
brokers, dealers and financial institutions such as banks and trust companies.
Such loans will be secured by collateral consisting of cash or U.S. Government
securities which will be maintained in an amount equal to at least 100% of the
current market value of the loaned securities.  During the period of the loan,
the Fund will receive the income on both the loaned securities and the
collateral and thereby increase its return.  Cash collateral will be invested
in short-term high quality debt securities, which will increase the current
income of the Fund.  The loans will be terminable by the Funds at any time and
by the borrower on one day's notice.  The Funds will have the right to regain
record ownership of loaned securities to exercise beneficial rights such as
rights to interest or other distributions or voting rights on important issues.
The Funds may pay reasonable fees to persons unaffiliated with the Funds for
services in arranging such loans.  Lending of portfolio securities involves a
risk of failure by the borrower to return the loaned securities, in which event
the Funds may incur a loss.

         SECURITIES TRANSACTIONS SUBJECT TO DELAYED SETTLEMENT.  As described
under "Investments, Techniques and Risk Factors" in each Fund's Prospectus,
securities may be





                                       4
<PAGE>   123
purchased for which the normal settlement date occurs later than the settlement
date which is normal for U.S. Government obligations.  In no event, however,
will the settlement date in the case of Intermediate Government Fund occur
later than the 29th day after the trade date.  Securities held in a Fund's
portfolio are subject to changes in value (both experiencing appreciation when
interest rates decline and depreciation when interest rates rise) based upon
the public's perception of the creditworthiness of the issuer and changes, real
or anticipated, in the level of interest rates.  Purchasing securities subject
to delayed settlement can involve a risk that the yields available in the
market when the delivery takes place may actually be higher than those obtained
in the transaction itself.  A separate account of the Fund consisting of cash
or liquid, high grade debt securities equal to the amount of the delayed
settlement commitments will be established at the Trust's custodian bank.  For
the purpose of determining the adequacy of the securities in the account, the
deposited securities will be valued at market value using the valuation
procedures for all other investments.  If the market or fair value of such
securities declines, additional cash or liquid, high grade debt securities will
be placed in the account daily so that the value of the account will equal the
amount of such commitments by the Fund.  On the settlement date of these
delayed settlement securities, the Fund will meet its obligations from the
available cash flow, sale of securities held in the separate account, sale of
other securities or, although it would not normally expect to do so, from sale
of the delayed settlement securities themselves (which may have a value greater
or lesser than the Fund's payment obligations).  Sale of securities to meet
such obligations will generally result in the realization of capital gains or
losses.

         WHEN-ISSUED AND FORWARD COMMITMENT SECURITIES.  The Funds may purchase
securities on a when-issued basis.  "When-issued" refers to securities whose
terms are available and for which a market exists, but which have not been
issued.  A Fund will engage in when-issued transactions with respect to
securities purchased for its portfolio in order to obtain what is considered to
be an advantageous price and yield at the time of the transaction.  For
when-issued transactions, no payment is made until delivery is due, often a
month or more after the purchase.

         When a Fund engages in when-issued transactions, it relies on the
seller to consummate the transaction.  The failure of the issuer or seller to
consummate the transaction may result in the Fund losing the opportunity to
obtain a price and yield considered to be advantageous.  The purchase of
securities on a when-issued basis also involves a risk of loss if the value of
the security to be purchased declines prior to the settlement date.

         On the date that a Fund enters into an agreement to purchase
securities on a when-issued basis, the Fund will segregate in a separate
account cash or short-term money market instruments equal in value to the
Fund's commitment.  These assets will be valued daily at market, and additional
cash or securities will be segregated in a separate account to the extent that
the total value of the assets in the account declines below the amount of the
when-issued commitments.

         REPURCHASE AGREEMENTS.  The Funds may enter into repurchase
agreements.  A repurchase agreement is a contract under which a Fund would
acquire a security for a relatively short period (generally not more than 7
days) subject to the obligation of the seller to repurchase





                                       5
<PAGE>   124
and the Fund to resell such security at a fixed time and price (representing
the Fund's cost plus interest).  A Fund will enter into repurchase agreements
only with member banks of the Federal Reserve System and with securities
dealers.  The Adviser will continuously monitor the creditworthiness of the
parties with whom a Fund enters into repurchase agreements.  The Funds have
established a procedure providing that the securities serving as collateral for
each repurchase agreement must be delivered to the Funds' custodian either
physically or in book-entry form and that the collateral must be marked to
market daily to ensure that each repurchase agreement is fully collateralized
at all times.  In the event of bankruptcy or other default by a seller of a
repurchase agreement, a Fund could experience delays in liquidating the
underlying securities and could experience losses, including the possible
decline in the value of the underlying securities during the period in which
the Fund seeks to enforce its rights thereto, possible subnormal levels of
income and lack of access to income during this period, and the expense of
enforcing its rights.

         GOVERNMENT SECURITIES.  Certain U.S. Government securities, including
U.S. Treasury bills, notes and bonds, and Government National Mortgage
Association certificates ("Ginnie Maes"), are supported by the full faith and
credit of the United States.  Certain other U.S. Government securities, issued
or guaranteed by Federal agencies or government sponsored enterprises, are not
supported by the full faith and credit of the United States, but may be
supported by the right of the issuer to borrow from the U.S.  Treasury.  These
securities include obligations of the Federal Home Loan Mortgage Corporation
("Freddie Macs"), and obligations supported by the credit of the
instrumentality, such as Federal National Mortgage Association Bonds ("Fannie
Maes").  No assurance can be given that the U.S. Government will provide
financial support to such Federal agencies, authorities, instrumentalities and
government sponsored enterprises in the future.

         MORTGAGE-BACKED SECURITIES.  The Funds may invest in mortgage
pass-through certificates and multiple-class pass-through securities, such as
real estate mortgage investment conduits ("REMIC") pass-through certificates,
collateralized mortgage obligations ("CMOs") and stripped mortgage-backed
securities ("SMBS"), and other types of "Mortgage-Backed Securities" that may
be available in the future.

         GUARANTEED MORTGAGE PASS-THROUGH SECURITIES.  Guaranteed mortgage
pass-through securities represent participation interests in pools of
residential mortgage loans and are issued by U.S. Governmental or private
lenders and guaranteed by the U.S. Government or one of its agencies or
instrumentalities, including but not limited to the Government National
Mortgage Association ("Ginnie Mae"), the Federal National Mortgage Association
("Fannie Mae") and the Federal Home Loan Mortgage Corporation ("Freddie Mac").
Ginnie Mae certificates are guaranteed by the full faith and credit of the U.S.
Government for timely payment of principal and interest on the certificates.
Fannie Mae certificates are guaranteed by Fannie Mae, a federally chartered and
privately owned corporation, for full and timely payment of principal and
interest on the certificates.  Freddie Mac certificates are guaranteed by
Freddie Mac, a corporate instrumentality of the U.S. Government, for timely
payment of interest and the ultimate collection of all principal of the related
mortgage loans.





                                       6
<PAGE>   125
         MULTIPLE-CLASS PASS-THROUGH SECURITIES AND COLLATERALIZED MORTGAGE
OBLIGATIONS.  CMOs and REMIC pass-through or participation certificates may be
issued by, among others, U.S. Government agencies and instrumentalities as well
as private lenders.  CMOs and REMIC certificates are issued in multiple classes
and the principal of and interest on the mortgage assets may be allocated among
the several classes of CMOs or REMIC certificates in various ways.  Each class
of CMOs or REMIC certificates, often referred to as a "tranche," is issued at a
specific adjustable or fixed interest rate and must be fully retired no later
than its final distribution date.  Generally, interest is paid or accrues on
all classes of CMOs or REMIC certificates on a monthly basis.

         Typically, CMOs are collateralized by Ginnie Mae, Fannie Mae or
Freddie Mac certificates but also may be collateralized by other mortgage
assets such as whole loans or private mortgage pass-through securities.  Debt
service on CMOs is provided from payments of principal and interest on the
underlying mortgaged assets and any reinvestment income thereon.

         A REMIC is a CMO that qualifies for special tax treatment under the
Code and invests in certain mortgages primarily secured by interests in real
property and other permitted investments.  Investors may purchase "regular" and
"residual" interest shares of beneficial interest in a REMIC, although the
Funds do not intend to invest in residual interests.

         STRIPPED MORTGAGE-BACKED SECURITIES.  SMBS are derivative
multiple-class mortgage-backed securities.  SMBS are usually structured with
two classes that receive different proportions of interest and principal
distributions on a pool of mortgage assets.  A typical SMBS will have one class
receiving some of the interest and most of the principal, while the other class
will receive most of the interest and the remaining principal.  In the most
extreme case, one class will receive all of the interest (the "interest only"
class) while the other class will receive all of the principal (the "principal
only" class).  The yields and market risk of interest only and principal only
SMBS, respectively, may be more volatile than those of other fixed income
securities.  The staff of the SEC considers privately issued SMBS to be
illiquid.

         STRUCTURED OR HYBRID NOTES.  The Funds may invest in "structured" or
"hybrid" notes.  The distinguishing feature of a structured or hybrid note is
that the amount of interest and/or principal payable on the note is based on
the performance of a benchmark asset or market other than fixed-income
securities or interest rates.  Examples of these benchmarks include stock
prices, currency exchange rates and physical commodity prices.  Investing in a
structured note allows a Fund to gain exposure to the benchmark market while
fixing the maximum loss that the Fund may experience in the event that market
does not perform as expected.  Depending on the terms of the note, a Fund may
forego all or part of the interest and principal that would be payable on a
comparable conventional note; the Fund's loss cannot exceed this foregone
interest and/or principal.  An investment in structured or hybrid notes
involves risks similar to those associated with a direct investment in the
benchmark asset.

         RISK FACTORS ASSOCIATED WITH MORTGAGE-BACKED SECURITIES.  Investing in
Mortgage-Backed Securities involves certain risks, including the failure of a
counter-party to meet its





                                       7
<PAGE>   126
commitments, adverse interest rate changes and the effects of prepayments on
mortgage cash flows.  In addition, investing in the lowest tranche of CMOs and
REMIC certificates involves risks similar to those associated with investing in
equity securities.  Further, the yield characteristics of Mortgage-Backed
Securities differ from those of traditional fixed income securities.  The major
differences typically include more frequent interest and principal payments
(usually monthly), the adjustability of interest rates, and the possibility
that prepayments of principal may be made substantially earlier than their
final distribution dates.

         Prepayment rates are influenced by changes in current interest rates
and a variety of economic, geographic, social and other factors and cannot be
predicted with certainty.  Both adjustable rate mortgage loans and fixed rate
mortgage loans may be subject to a greater rate of principal prepayments in a
declining interest rate environment and to a lesser rate of principal
prepayments in an increasing interest rate environment.  Under certain interest
rate and prepayment rate scenarios, a Fund may fail to recoup fully its
investment in Mortgage-Backed Securities notwithstanding any direct or indirect
governmental, agency or other guarantee.  When the Fund reinvests amounts
representing payments and unscheduled prepayments of principal, it may receive
a rate of interest that is lower than the rate on existing adjustable rate
mortgage pass-through securities.  Thus, Mortgage-Backed Securities, and
adjustable rate mortgage pass-through securities in particular, may be less
effective than other types of U.S.  Government securities as a means of
"locking in" interest rates.

         Conversely, in a rising interest rate environment, a declining
prepayment rate will extend the average life of many Mortgage-Backed
Securities.  This possibility is often referred to as extension risk.
Extending the average life of a Mortgage- Backed Security increases the risk of
depreciation due to future increases in market interest rates.

         RISK ASSOCIATED WITH SPECIFIC TYPES OF DERIVATIVE DEBT SECURITIES.
Different types of derivative debt securities are subject to different
combinations of prepayment, extension and/or interest rate risk.  Conventional
mortgage pass-through securities and sequential pay CMOs are subject to all of
these risks, but are typically not leveraged.  Thus, the magnitude of exposure
may be less than for more leveraged Mortgage-Backed Securities.

         The risk of early prepayments is the primary risk associated with
interest only debt securities ("IOs"), super floaters, other leveraged floating
rate instruments and Mortgage-Backed Securities purchased at a premium to their
par value.  In some instances, early prepayments may result in a complete loss
of investment in certain of these securities.  The primary risks associated
with certain other derivative debt securities are the potential extension of
average life and/or depreciation due to rising interest rates.

         These securities include floating rate securities based on the Cost of
Funds Index ("COFI floaters"), other "lagging rate" floating rate securities,
floating rate securities that are subject to a maximum interest rate ("capped
floaters"), Mortgage-Backed Securities purchased at a discount, leveraged
inverse floating rate securities ("inverse floaters"), principal only debt
securities ("POs"), certain residual or support tranches of CMOs and index
amortizing notes.  Index

amortizing notes are not Mortgage-Backed Securities, but are subject to
extension risk resulting from the issuer's failure to exercise its option to
call or redeem the notes before their stated maturity date.  Leveraged inverse
IOs combine several elements of the Mortgage-Backed Securities described above
and thus present an especially intense combination of prepayment, extension and
interest rate risks.

         Planned amortization class ("PAC") and target amortization class
("TAC") CMO bonds involve less exposure to prepayment, extension and interest
rate risk than other Mortgage-Backed Securities, provided that prepayment rates
remain within expected prepayment ranges or "collars."  To the extent that
prepayment rates remain within these prepayment ranges, the residual or support
tranches of PAC and TAC CMOs assume the extra prepayment, extension and
interest rate risk associated with the underlying mortgage assets.

         Other types of floating rate derivative debt securities present more
complex types of interest rate risks.  For example, range floaters are subject
to the risk that the coupon will be reduced to below market rates if a
designated interest rate floats outside of a specified interest rate band or
collar.  Dual index or yield curve floaters are subject to depreciation in the
event of an unfavorable change in the spread between two designated interest
rates.  X-reset floaters have a coupon that remains fixed for more than one
accrual period.  Thus, the type of risk involved in these securities depends on
the terms of each individual X-reset floater.

         The Funds are permitted to engage in certain hedging techniques
involving options and futures transactions in order to reduce the effect of
interest rate movements affecting the market values of the investments held, or
intended to be purchased, by the Funds.

         OPTIONS ON DEBT SECURITIES.  The U.S. Government Fund may purchase put
and call options on debt securities which are traded on a national securities
exchange (an "Exchange") to protect its holdings in an underlying or related
security against a substantial decline in market value.  Securities are
considered related if their price movements generally correlate to one another.
The purchase of put options on debt securities which are related to securities
held in its portfolio will enable the Fund to protect, at least partially,
unrealized gains in an appreciated security in its portfolio without actually
selling the security.  In addition, the Fund may continue to receive interest
income on the security.  The purchase of call options on debt securities may
help to protect against substantial increases in prices of securities the Fund
intends to purchase pending its ability to invest in such securities in an
orderly manner.
         The U.S. Government Fund may sell put and call options it has
previously purchased, which could result in a net gain or loss depending on
whether the amount realized on the sale is more or less than the premium and
other transaction costs paid in connection with the option which is sold.

         The purchase of put and call options involves certain risks.  If a put
or call option purchased by the U.S. Government Fund is not sold when it has
remaining value, and if the market price of the underlying security remains
equal to or greater than the exercise price, in the case of a put, or equal to
or less than the exercise price, in the case of a call, the Fund will lose its





                                       9
<PAGE>   128
entire investment in the option.  Also, where a put or a call option on a
particular security is purchased to hedge against price movements in a related
security, the price of the put or call option may move more or less than the
price of the related security.

         The U.S. Government Fund will not invest in a put or a call option if
as a result the amount of premiums paid for such options then outstanding would
exceed 10% of the Fund's total assets.

         FUTURES CONTRACTS AND RELATED OPTION.  The Funds may engage in the
purchase and sale of interest rate futures contracts ("financial futures") and
related options for the purposes and subject to the limitations described
below.  Currently, the Funds may engage in such transactions with respect to
U.S. Treasury Bonds, U.S. Treasury Notes, and GNMA's on the Chicago Board of
Trade and with respect to U.S. Treasury bills on the International Money Market
at the Chicago Mercantile Exchange.

         The Intermediate Government Fund may purchase financial futures
contracts only as a hedge against changes in the general level of interest
rates.  The U.S. Government Fund may purchase financial futures contracts only
to close an existing short position in a futures contract.  The purchase of a
financial futures contract obligates the buyer to accept and pay for the
specific type of debt security called for in the contract at a specified future
time and at a specified price.  A Fund would purchase a financial futures
contract when it is not fully invested in long-term debt securities but wishes
to defer its purchases for a time until it can invest in such securities in an
orderly manner or because short-term yields are higher than long-term yields.
Such purchases would enable the Fund to earn the income on a short-term
security while at the same time minimizing the effect of all or part of an
increase in the market price of the long-term debt security which the Fund
intends to purchase in the future.  A rise in the price of the long-term debt
security prior to its purchase either would generally be offset by an increase
in the value of the futures contract purchased by the Fund or avoided by taking
delivery of the debt securities under the futures contract.

         The Funds may sell financial futures contracts only as a hedge against
changes in interest rates.  The sale of a financial futures contract obligates
the seller to deliver the specific type of debt security called for in the
contract at a specified future time and at a specified price.  A Fund would
sell a financial futures contract in order to continue to receive the income
from a long-term debt security, while endeavoring to avoid part or all of the
decline in market value of that security which would accompany an increase in
interest rates.  If interest rates did rise, a decline in the value of the debt
security held by the Fund would be substantially offset by an increase in the
value of the futures contract sold by the Fund.  While the Fund could sell a
long-term debt security and invest in a short-term security, ordinarily the
Fund would give up income on its investment, since long-term rates normally
exceed short-term rates.

         In addition, the Funds may engage in certain transactions involving
put and call options on financial futures contracts to hedge against changes in
interest rates.  The U.S. Government Fund may purchase put and call options and
sell call options on financial futures contracts for hedging





                                       10
<PAGE>   129
purposes and may enter into closing transactions with respect to such options
to close an existing position.  The Intermediate Government Fund may purchase
put and call options on financial futures contracts which are traded on a
securities exchange or board of trade for hedging purposes and may also enter
into closing transactions with respect to such options to close an existing
position.  Options on financial futures contracts are similar to options on
securities except that a put option on a financial futures contract gives the
purchaser the right in return for the premium paid to assume a short position
in a financial futures contract and a call option on a financial futures
contract gives the purchaser the right in return for the premium paid to assume
a long position in a financial futures contract.

         A Fund may hedge up to the full value of its portfolio through the use
of options and futures.  At the time a Fund purchases a financial futures
contract or a call option on such a futures contract, an amount of cash or U.S.
Government Securities at least equal to the market value of the futures
contract will be deposited in a segregated account with the Funds' Custodian to
collateralize the position and thereby insure that such futures contract is
unleveraged.  A Fund may not purchase or sell futures contracts or related put
or call options if immediately thereafter the sum of the amount of margin
deposits on the Fund's existing futures and related options positions and the
amount of premiums paid for related options (measured at the time of
investment) would exceed 5% of the Fund's total assets.

         While a Fund's hedging transactions may protect the Fund against
adverse movements in the general level of interest rates, such transactions
could also preclude the opportunity to benefit from favorable movements in the
level of interest rates.  Due to the imperfect correlation between movements in
the prices of futures contracts and movements in the prices of the related
securities being hedged, the price of a futures contract may move more than or
less than the price of the securities being hedged.  Options on futures
contracts are generally subject to the same risks applicable to all option
transactions.  In addition, a Fund's ability to use this technique will depend
in part on the development and maintenance of a liquid secondary market for
such options.  For a discussion of the inherent risks involved with futures
contracts and options thereon, see "Risks Relating to Transactions in Futures
Contracts and Related Options" below.

         The Funds' policies permitting the purchase and sale of futures
contracts and certain related put or call options only for hedging purposes may
not be changed without the approval of shareholders holding a majority of the
applicable Fund's outstanding voting securities.  The Board of Trustees may
authorize procedures, including numerical limitations, with regard to such
transactions in furtherance of a Fund's investment objectives.  Such procedures
are not deemed to be fundamental and may be changed by the Board of Trustees
without the vote of the Fund's shareholders.

         The U.S. Government Fund is also authorized to, but presently does not
intend to, engage in certain investment techniques involving the sale of
covered call and secured put options for the purpose of generating additional
income.  The Fund will not engage in such transactions without first having
given shareholders at least 60 days' written notice.

         RISKS RELATING TO TRANSACTIONS IN FUTURES CONTRACTS AND RELATED
OPTION.  Positions in futures contracts may be closed out only on an exchange
or board of trade which provides a market for such futures.  Although the Funds
intend to purchase or sell futures contracts only on exchanges or boards of
trade where there appears to be an active market, there is no assurance that a
liquid market on an exchange or board of trade will exist for any particular
contract or at any particular time.  In the event a liquid market does not
exist, it may not be possible to close a futures position, and in the event of
adverse price movements, an affected Fund would continue to be required to make
daily cash payments of maintenance margin.  In addition, limitations imposed by
an exchange or board of trade on which futures contracts are traded may compel
or prevent a Fund from closing out a contract which may result in reduced gain
or increased loss to the Fund.  The absence of a liquid market in futures
contracts might cause a Fund to make or take delivery of the underlying
securities at a time when it may be disadvantageous to do so.  The purchase of
put options on futures contracts involves less potential dollar risk to the
Fund than an investment of equal amount in futures contracts, since the premium
is the maximum amount of risk the purchaser of the option assumes.  The entire
amount of the premium paid for an option can be lost by the purchaser, but no
more than that amount.

      SPECIAL CONSIDERATIONS APPLICABLE TO OPTIONS ON U.S. GOVERNMENT SECURITIES

         Treasury Bonds and Notes.  Because trading interest in options written
on Treasury bonds and notes tends to center on the most recently auctioned
issues, the Exchanges will not continue indefinitely to introduce options with
new expirations to replace expiring options on particular issues.  Instead, the
expirations introduced at the commencement of options trading on a particular
issue will be allowed to run their course, with the possible addition of a
limited number of new expirations as the original ones expire.  Options trading
on each issue of bonds or notes will thus be phased out as new options are
listed on more recent issues, and options representing a full range of
expirations will not ordinarily be available for every issue on which options
are traded.

         Treasury Bills.  Because the deliverable Treasury bill changes from
week to week, writers of Treasury bill calls cannot provide in advance for
their potential exercise settlement obligations by acquiring and holding the
underlying security.  However, if the U.S. Government Fund holds a long
position in Treasury bills with a principal amount corresponding to the
principal amount of the securities deliverable upon exercise of the option, it
may be hedged from a risk standpoint.  In addition, the U.S. Government Fund
will maintain Treasury bills maturing no later than those which would be
deliverable in the event of an assignment of an exercise notice in a segregated
account with its Custodian so that it will be treated as being covered for
margin purposes.
         GNMA Certificates.  The following special considerations will be
applicable to the writing of call options on GNMA Certificates by U.S.
Government Fund when and if trading of options thereon commences.  Since the
remaining principal balance of GNMA Certificates declines each month as a
result of mortgage payments, the U.S. Government Fund as a writer of a GNMA
call holding GNMA Certificates as "cover" to satisfy its delivery obligation in
the event of exercise may find that the GNMA Certificates it holds no longer
have a sufficient remaining principal balance for this purpose.  Should this
occur, the Fund will purchase additional GNMA Certificates





                                       12
<PAGE>   131
from the same pool (if obtainable) or replacement GNMA Certificates in the cash
market in order to maintain its cover.  If for any reason, the Fund were no
longer covered, the Fund will either enter into a closing purchase transaction
or replace such Certificate with a Certificate which represents cover.  When
the Fund closes its position or replaces such Certificate, it may realize an
unanticipated loss and incur transaction costs.

INVESTMENT RESTRICTIONS

         Each Fund has adopted certain fundamental investment restrictions.
The fundamental restrictions set forth below as well as the Funds' investment
objectives and fundamental policies and restrictions set forth in the
Prospectuses may not be changed without approval of a majority of the
applicable Fund's outstanding voting securities.  Under the Investment Company
Act of 1940, as amended (the "1940 Act"), and as used in the Prospectuses and
this SAI, a "majority of the outstanding voting securities" requires the
approval of the lesser of (1) the holders of 67% or more of the shares of a
Fund represented at a meeting if the holders of more than 50% of the
outstanding shares of the Fund are present in person or by proxy or (2) the
holders of more than 50% of the outstanding shares of the Fund.

         Under these restrictions, a Fund may not:

         1.      Make short sales of securities or purchase securities on
       margin, except for such short-term loans as are necessary for the
       clearance of purchases of portfolio securities.

         2.      Engage in the underwriting of securities except insofar as the
       Fund may be deemed an underwriter under the Securities Act of 1933 in
       disposing of a portfolio security or purchase securities which are not
       readily marketable.

         3.      Purchase or sell real estate or interests therein, including
       limited partnership interests although the Fund may purchase securities
       of issuers which engage in real estate operations and securities which
       are secured by real estate or interests therein.
         4.      Purchase oil, gas or other mineral leases, rights or royalty
       contracts or exploration or development programs, except that the Trust
       may invest in securities of companies which invest in or sponsor such
       programs.

         5.      Purchase securities of other investment companies, except in
       connection with a merger, consolidation, reorganization or acquisition
       of assets.

         6.      Invest for the purpose of exercising control or management of
                 another company.

         7.      Invest in securities of any company if, to the knowledge of
       the Trust, any officer or director of the Trust or its Adviser owns more
       than 1/2 of 1% of the outstanding securities of such company, and all
       such officers and directors own in the aggregate more than 5% of the
       outstanding securities of such company.





                                       13
<PAGE>   132
         8.      Issue senior securities, as defined in the Act, except that
       the Fund may enter into repurchase agreements, lend portfolio
       securities, and borrow as described below.

         9.      Make loans of money or securities, except by (a) the purchase
       of fixed income obligations; (b) investing in repurchase agreements; or
       (c) lending its portfolio securities.  See "Investments, Techniques and
       Risk Factors" in the Prospectus.

         10.     Write or purchase put or call options or purchase or sell
     commodities or commodity futures contracts except the Fund may purchase
     such options on debt securities and purchase or sell financial futures
     contracts and purchase options thereon.

         11.     Invest in warrants or rights except where acquired in units or
     attached to other securities.

         12.     Enter into a repurchase agreement maturing in more than seven
     days, if as a result such repurchase agreements together with restricted
     securities and securities for which there are no readily available market
     quotations would constitute more than 10% of the Fund's total assets, or
     enter into reverse repurchase agreements exceeding in the aggregate
     one-third of the market value of the Fund's total assets less liabilities
     other than obligations created by reverse repurchase agreements.

         13.     Invest more than 5% of the market or other fair value of its
     assets in the securities of any one issuer and shall not purchase more
     than 10% of the voting securities or more than 10% of any class of
     securities of any one issuer.  This restriction does not apply to U.S.
     Government securities as defined in the Prospectuses.

         14.     Borrow in excess of 15% of the market or fair value of its
     total assets or pledge its assets to an extent greater than 10% of the
     market or other fair value of its total assets.  Borrowings must be from
     banks and undertaken only as a temporary measure for extraordinary or
     emergency purposes.  Collateral arrangements maintained in connection with
     the writing of covered call options or margin deposits in connection with
     the sale of futures contracts and related options are not deemed to be a
     pledge or other encumbrance.  The restriction on borrowing does not
     prohibit the use of reverse repurchase agreements in an amount (including
     any borrowings) not to exceed 33 1/3% of the Fund's net assets.

         In addition, U.S. Government Fund may invest only in those investments
which a federally chartered savings and loan association by law or regulation
may, without limitation as to percentage of assets, invest in, sell, redeem,
hold or otherwise deal with.  The Intermediate Government Trust may not invest
more than 25% of its total assets in the securities of issuers in any single
industry, provided that there shall be no such limitation on the purchase of
obligations issued or guaranteed by the U.S. Government or its agencies or
instrumentalities.





                                       14
<PAGE>   133
         Notwithstanding any investment restriction to the contrary, the Funds
may, in connection with the John Hancock Group of Funds Deferred Compensation
Plan for Independent Trustees/Directors, purchase securities of other
investment companies within the John Hancock Group of Funds provided that, as a
result, (i) no more than 10% of the Fund's assets would be invested in
securities of all other investment companies, (ii) such purchase would not
result in more than 3% of the total outstanding voting securities of any one
such investment company being held by the Fund and (iii) no more than 5% of the
Fund's assets would be invested in any one such investment company.

THOSE RESPONSIBLE FOR MANAGEMENT

         The business of the Funds is managed by the Trust's Trustees who elect
officers who are responsible for the day-to-day operations of each Fund and who
execute policies formulated by the Trustees.  Several of the officers and
Trustees of the Trust are also officers and directors of the Adviser or
officers and directors of John Hancock Funds.

         Set forth below is the principal occupation or employment of the
Trustees and officers of the Trust during the past five years.

INVESTMENT ADVISORY AND OTHER SERVICES

         As described in the Prospectus, the Funds receive their investment
advice from the Adviser.  Investors should refer to the Prospectuses for a
description of certain information concerning the investment management
contracts.  Each of the Trustees and principal officers affiliated with the
Trust who is also an affiliated person of the Adviser is named above, together
with the capacity in which such person is affiliated with the Trust or the
Adviser.

         The Adviser, located at 101 Huntington Avenue, Boston, Massachusetts
02199-7603, was organized in 1968 and currently has over $13 billion in assets
under management in its capacity as investment adviser to the Funds and the
other mutual funds and publicly traded investment companies in the John Hancock
group of funds having a combined total of over 1,060,000 shareholders.  The
Adviser is a wholly-owned subsidiary of The Berkeley Financial Group, which is
in turn a wholly-owned subsidiary of John Hancock Subsidiaries, Inc., which is
in turn a wholly-owned subsidiary of the Life Company, one of the most
recognized and respected financial institutions in the nation.  With total
assets under management of over $80 billion, the Life Company is one of the ten
largest life insurance companies in the United States, and carries Standard &
Poor's and A.M. Best's highest ratings.  Founded in 1862, the Life Company has
been serving clients for over 130 years.

         As described in the Prospectus under the caption "Organization and
Management of the Fund," the Trust, on behalf of each Fund, has entered into an
investment management contract with the Adviser.  Under the investment
management contracts, the Adviser provides the Funds with (i) a continuous
investment program, consistent with each Fund's stated investment objective and
policies, (ii) supervision of all aspects of the Funds' operations except those
that are delegated to a custodian, transfer agent or other agent and (iii) such
executive, administrative and clerical




                                       27
<PAGE>   146
personnel, officers and equipment as are necessary for the conduct of their
business.  The Adviser is responsible for the day-to-day management of each
Fund's portfolio assets.

         No person other than the Adviser and its directors and employees
regularly furnishes advice to the Funds with respect to the desirability of the
Funds investing in, purchasing or selling securities.  The Adviser may from
time to time receive statistical or other similar factual information, and
information regarding general economic factors and trends, from the Life
Company and its affiliates.

         Under the terms of the investment management contracts with the Funds,
the Adviser provides the Trust with office space, equipment and supplies and
other facilities and personnel required for the business of the Trust.  The
Adviser pays the compensation of all officers and employees of the Trust and
pays the expenses of clerical services relating to the administration of each
Fund.  All expenses which are not specifically paid by the Adviser and which
are incurred in the operation of the Trust including, but not limited to, (i)
the fees of the Independent Trustees, (ii) the fees of the members of the
Trust's Advisory Board (described above) and (iii) the continuous public
offering of the shares of the Funds are borne by the Funds and/or the other
series of the Trust.  Subject to the conditions set forth in a private letter
ruling that the Funds have received from the Internal Revenue Service relating
to their multiple-class structure, class expenses properly allocable to any
Class A or Class B shares will be borne exclusively by such class of shares.

         The investment management contract with the Trust, on behalf of
Intermediate Government Fund, provides that the Trust shall pay the Adviser for
its services, out of the assets of Intermediate Government Fund, a monthly fee,
computed at the annual rate of 0.50% of the average daily net assets of
Intermediate Government Fund.  Prior to April 1, 1993, investment advisory fees
paid by the Intermediate Government Fund amounted to 0.45% of its average daily
net assets.  On February 16, 1993, the Trust's Board of Trustees, including all
of the Independent Trustees, approved an amendment to the investment management
contract whereby the fee payable to the Fund's prior investment adviser under
the investment management contract be increased to 0.50% of the average daily
net assets of Intermediate Government Fund, and at a meeting on March 29, 1993,
shareholders of Intermediate Government Fund approved the amended investment
management contract.

         The investment management contract with the Trust, on behalf of U.S.
Government Fund, provides that the Trust shall pay the Adviser for its
services, out of the assets of U.S. Government Fund, a monthly fee, computed at
the following rates:

<PAGE>   147
         The Adviser may voluntarily and temporarily reduce its advisory fee or
make other arrangements to limiteach Fund's expenses to a specified percentage
of its average daily net assets.  The Adviser retains the right to re-impose
the advisory fee and recover any other payments to the extent that, at the end
of any fiscal year, such Fund's annual expenses fall below this limit.

         In the event normal operating expenses of a Fund, exclusive of certain
expenses prescribed by state law, are in excess of any state limit where that
Fund is registered to sell shares of beneficial interest, the fee payable to
the Adviser will be reduced to the extent of such excess and the Adviser will
make any additional arrangements necessary to eliminate any remaining excess
expenses.  Currently, the most restrictive limit applicable to each Fund is
2.5% of the first $30,000,000 of the Fund's average daily net asset value, 2%
of the next $70,000,000 and 1.5% of the remaining average daily net asset
value.

         Pursuant to the investment management contracts, the Adviser is not
liable to the Funds or their shareholders for any error of judgment or mistake
of law or for any loss suffered by a Fund in connection with the matters to
which their respective contracts relate, except a loss resulting from willful
misfeasance, bad faith or gross negligence on the part of the Adviser in the
performance of its duties or from its reckless disregard of the obligations and
duties under the applicable contract.

         The term of each investment management contract expires on December
22, 1996 and each contract will continue in effect from year to year thereafter
if approved annually by a vote of a majority of the Independent Trustees of the
Trust, on behalf of the affected Fund, cast in person at a meeting called for
the purpose of voting on such approval, and by either a majority of the
Trustees or the holders of a majority of the affected Fund's outstanding voting
securities.  A management contract may, on 60 days' written notice, be
terminated at any time without the payment of any penalty by the affected Fund
by vote of a majority of the outstanding voting securities of the affected
Fund, by the Trustees or by the Adviser.  A management contract terminates
automatically in the event of its assignment.

         Securities held by the Funds may also be held by other funds or
investment advisory clients for which the Adviser or its affiliates provide
investment advice.  Because of different investment objectives or other
factors, a particular security may be bought for one or more funds or clients
when one or more are selling the same security.  If opportunities for the
purchase or sale of securities by the Adviser or for other funds or clients for
which the Adviser renders investment advice arise for consideration at or about
the same time, transactions in such securities will be made, insofar as
feasible, for the respective funds or clients in a manner deemed equitable to
all of them.  To the extent that transactions on behalf of more than one client
of the Adviser or its affiliates may increase the demand for securities being
purchased or the supply of securities being sold, there may be an adverse
effect on price.





                                       29
<PAGE>   148
         Under the investment management contracts, the Funds may use the name
"John Hancock" or any name derived from or similar to it only as long as the
applicable investment management contract or any extension, renewal or
amendment thereof remains in effect.  If a Fund's investment management
contract is no longer in effect, that Fund (to the extent that it lawfully can)
will cease to use such name or any other name indicating that it is advised by
or otherwise connected with the Adviser.  In addition, the Adviser or the Life
Company may grant the non-exclusive right to use the name "John Hancock" or any
similar name to any other corporation or entity, including but not limited to
any investment company of which the Life Company or any subsidiary or affiliate
thereof or any successor to the business of any subsidiary or affiliate thereof
shall be the investment adviser.

         For the fiscal years ended March 31, 1993, 1994 and 1995, advisory
fees payable by Intermediate Government Fund to TFMC amounted to $6,588,
$24,447 and $35,445 respectively; and $10,219 to John Hancock Adviser's during
the fiscal year ended March 31, 1995 however, a portion of such fees was not
imposed pursuant to the voluntary fee and expense limitation arrangements then
in effect (see "Financial Highlights" in the Prospectus).  For the fiscal years
ended March 31, 1993, 1994 and 1995, advisory fees payable by U.S. Government
Fund to TFMC amounted to $128,579, $143,566 and $105,080 respectively and
$30,022 to John Hancock Advisers during the fiscal year ended March 31, 1995.

         ADMINISTRATIVE SERVICES AGREEMENT.  The Trust, on behalf of the Funds,
was a party to administrative services agreements with TFMC (the "Services
Agreements"), pursuant to which TFMC performed bookkeeping and accounting
services and functions, including preparing and maintaining various accounting
books, records and other documents and keeping such general ledgers and
portfolio accounts as are reasonably necessary for the operation of the Funds.
Other administrative services included communications in response to
shareholder inquiries and certain printing expenses of various financial
reports.  In addition, such staff and office space, facilities and equipment
was provided as necessary to provide administrative services to the Funds.  The
Services Agreements were amended in connection with the appointment of the
Adviser as adviser to the Funds to permit services under the Agreements to be
provided to the Funds by the Adviser and its affiliates.  The Services
Agreements were terminated during the current fiscal year.


DISTRIBUTION CONTRACTS

         DISTRIBUTION CONTRACTS.   As discussed in the Prospectuses, each
Fund's shares are sold on a continuous basis at the public offering price.
John Hancock Funds, a wholly-owned subsidiary of the Adviser, has the exclusive
right, pursuant to the Distribution Contracts dated December 22, 1994 (the
"Distribution Contracts"), to purchase shares from the Funds at net asset value
for resale to the public or to broker-dealers at the public offering price.
Upon notice to all broker-dealers ("Selling Brokers") with whom it has sales
agreements, John Hancock Funds may allow such Selling Brokers up to the full
applicable sales charge during periods specified in such notice.  During these
periods, such Selling Brokers may be deemed to be underwriters as that term is
defined in the Securities Act of 1933.





                                       30
<PAGE>   149
         The Distribution Contracts were initially adopted by the affirmative
vote of the Trust's Board of Trustees including the vote a majority of the
Independent Trustees cast in person at a meeting called for such purpose.  Each
Distribution Contract shall continue in effect until December 22, 1995 and from
year to year thereafter if approved by either the vote of the relevant Fund's
shareholders or the Board of Trustees, including the vote of a majority of the
Independent Trustees, cast in person at a meeting called for such purpose.  A
Distribution Contract may be terminated at any time, without penalty, by either
party upon sixty (60) days' written notice or by a vote of a majority of the
outstanding voting securities of the relevant Fund and terminates automatically
in the case of an assignment by John Hancock Funds.

         Total underwriting commissions for sales of the Class A shares of
Intermediate Government Fund and U.S. Government Fund for the fiscal years
ended March 31, 1993 were $5,066 and $2,267; for 1994 were $0 and $172 and for
1995 were $34,289 and $33,470 respectively.  Of the amounts, for sales of Class
A shares of Intermediate Government Fund, $215, $0 and $3,185 was retained by
Transamerica Fund Distributors, Inc., the Funds' former distributor,(or the
Funds current distributor) for the fiscal years ended March 31, 1993, 1994 and
1995, respectively, and the remainders were reallowed to dealers.  For sales of
Class A shares of U.S.  Government Fund, $104, $0 and $2,778 was retained by
Transamerica Fund Distributors, Inc., the Fund's former distributor or the
Fund's current distributor, for the fiscal years ended March 31, 1993, 1994 and
1995, respectively, and the remainders were reallowed to dealers.

         DISTRIBUTION PLAN.  The Board of Trustees, including the Independent
Trustees of the Trust, approved new distribution plans for each Fund pursuant
to Rule 12b-1 under the 1940 Act for  Class A shares ("Class A Plans") and
Class B shares ("Class B Plans").  Such Plans were approved by a majority of
the outstanding shares of each respective class on December 16, 1994 and became
effective on December 22, 1994.

         Under the Class A Plans, the distribution or service fee will not
exceed an annual rate of 0.25% of the average daily net asset value of the
Class A shares of the Funds (determined in accordance with the appropriate
Fund's Prospectus as from time to time in effect).  Any expenses under a Fund's
Class A Plan not reimbursed within 12 months of being presented to such Fund
for repayment are forfeited and not carried over to future years.  Under the
Class B Plans, the distribution or service fee to be paid by the Funds will not
exceed an annual rate of 1.00% of the average daily net assets of the Class B
shares of the Funds (determined in accordance with the appropriate Fund's
prospectus as from time to time in effect); provided that the portion of such
fee used to cover Service Expenses (described below) shall not exceed an annual
rate of 0.25% of the average daily net asset value of the Class B shares of the
respective Fund.  Under the Class B Plans, the fee covers the Distribution and
Service Expenses (described below) and interest expenses on unreimbursed
distribution expenses.  In accordance with generally accepted accounting
principles, the Funds do not treat unreimbursed distribution expenses as a
liability of the Fund and do not reduce the current net assets of Class B
shares by such amount, although the amount may be payable in the future.


                                       31
<PAGE>   150
         Under the Plans, expenditures shall be calculated and accrued daily
and paid monthly or at such other intervals as the Trustees shall determine.
The fee may be spent by John Hancock Funds on Distribution Expenses or Service
Expenses.  "Distribution Expenses" include any activities or expenses primarily
intended to result in the sale of shares of the relevant class of the Funds,
including, but not limited to:  (i) initial and ongoing sales compensation
payable out of such fee as such compensation is received by John Hancock Funds
or by Selling Brokers, (ii) direct out-of-pocket expenses incurred in
connection with the distribution of shares, including expenses related to
printing of prospectuses and reports; (iii) preparation, printing and

the distribution of Fund Shares (v) distribution expenses that were incurred by
a Fund's former distributor and not recovered through payments under the Class
A or Class B former plans or through receipt of contingent deferred sales
charges; and (vi) in the event that any other investment company (the "Acquired
Fund") sells all or substantially all of its assets to merges with or otherwise
engages in a combination with a Fund, distribution expenses originally incurred
in connection with the distribution of the Acquired Fund's shares.  Service
Expenses under the Plans include payments made to, or on account of, account
executives of selected broker-dealers (including affiliates of John Hancock
Funds) and others who furnish personal and shareholder account maintenance
services to shareholders of the relevant class of the Fund.

         Each of the Plans provides that it will continue in effect only as
long as its continuance is approved at least annually by a majority of both the
Trustees and the Independent Trustees.  Each of the Plans provides that it may
be terminated (a) at any time by vote of a majority of the Trustees, a majority
of the Independent Trustees, or a majority of the respective Class' outstanding
voting securities or (b) by John Hancock Funds on 60 days' notice in writing to
the affected Fund.   Each of the Plans further provides that it may not be
amended to increase the maximum amount of the fees for the services described
therein without the approval of a majority of the outstanding shares of the
class of the affected Fund which has voting rights with respect to the Plan.
Each of the Plans provides that no material amendment to the Plan will, in any
event, be effective unless it is approved by a majority vote of the Trustees
and the Independent Trustees of the Trust.  The holders of Class A shares and
Class B shares have exclusive voting rights with respect to the Plan applicable
to their respective class of shares of the Fund in which they are shareholders.
In adopting the Plans, the Board of Trustees has determined that, in its
judgment, there is a reasonable likelihood that the Plans will benefit the
holders of the applicable class of shares of the Funds.

         Information regarding the services rendered under the Plans and the
Distribution Contracts and the amounts paid therefor by the respective Class of
the Funds are provided to, and reviewed by, the Board of Trustees on a
quarterly basis.  In its quarterly review, the Board of Trustees considers the
continued appropriateness of the Plans and the Distribution Contracts and the
level of compensation provided therein.

         When the Trust seeks an Independent Trustee to fill a vacancy or as a
nominee for election by shareholders, the selection or nomination of the
Independent Trustee is, under resolutions adopted by the Trustees
contemporaneously with their adoption of the Plans, committed to the discretion
of the Committee on Administration of the Trustees.  The members of the
Committee on Administration are all Independent Trustees and identified in this
Statement of Additional Information under the heading "Those Responsible for
Management."

NET ASSET VALUE

         For purposes of calculating the net asset value ("NAV") of a Fund's
shares, the following procedures are utilized wherever applicable.





                                       33
<PAGE>   152
         Debt investment securities are valued on the basis of valuations
furnished by a principal market maker or a pricing service, both of which
generally utilize electronic data processing techniques to determine valuations
for normal institutional size trading units of debt securities without
exclusive reliance upon quoted prices.

         Short-term debt investments which have a remaining maturity of 60 days
or less are generally valued at amortized cost, which the Trustees have
determined approximates market value.  If market quotations are not readily
available or if in the opinion of the Adviser any quotation or price is not
representative of true market value, the fair value of the security may be
determined in good faith in accordance with procedures approved by the
Trustees.

         A Fund will not price its securities on the following national
holidays:  New Year's Day; Presidents' Day; Good Friday; Memorial Day;
Independence Day; Labor Day; Thanksgiving Day; and Christmas Day.

INITIAL SALES CHARGE ON CLASS A SHARES

         The sales charges applicable to purchases of Class A shares of the
Funds are described in each Fund's Class A and Class B Prospectus.  Methods of
obtaining reduced sales charges referred to generally in the Prospectuses are
described in detail below.  In calculating the sales charge applicable to
current purchases of Class A shares, the investor is entitled to cumulate
current purchases with the greater of the current value (at offering price) of
the Class A shares of such Fund, or if Investor Services is notified by the
investor's dealer or the investor at the time of the purchase, the cost of the
Class A shares owned.

         COMBINED PURCHASES.  In calculating the sales charge applicable to
purchases of Class A shares made at one time, the purchases will be combined if
made by (a) an individual, his or her spouse and their children under the age
of 21 purchasing securities for his or her own account, (b) a trustee or other
fiduciary purchasing for a single trust, estate or fiduciary account and (c)
certain groups of four or more individuals making use of salary deductions or
similar group methods of payment whose funds are combined for the purchase of
mutual fund shares.  Further information about combined purchases, including
certain restrictions on combined group purchases, is available from Investor
Services or a Selling Broker's representative.

         WITHOUT SALES CHARGE.  As described in the Prospectuses, Class A
shares of the Funds may be sold without a sales charge to certain persons
described in the Prospectuses.

         ACCUMULATION PRIVILEGE.  Investors (including investors combining
purchases) who are already Class A shareholders may also obtain the benefit of
the reduced sales charge by taking into account not only the amount then being
invested but also the purchase price or value of the Class A shares already
held by such person.





                                       34
<PAGE>   153
         COMBINATION PRIVILEGE.  Reduced sales charges (according to the
schedule set forth in each Fund's Class A and Class B Prospectus) also are
available to an investor based on the aggregate amount of his concurrent and
prior investments in Class A shares of such Fund and shares of all other John
Hancock funds which carry a sales charge.

         LETTER OF INTENTION.  The reduced sales loads are also applicable to
investments made over a specified period pursuant to a Letter of Intention
(LOI), which should be read carefully prior to its execution by an investor.
The Funds offer two options regarding the specified period for making
investments under the LOI.  All investors have the option of making their
investments over a period of thirteen (13) months.  Investors who are using the
Funds as a funding medium for a qualified retirement plan, however, may opt to
make the necessary investments called for by the LOI over a forty-eight (48)
month period.  These qualified retirement plans include IRAs, SEP, SARSEP, TSA,
401(k) plans, TSA plans and 457 plans.  Such an investment (including
accumulations and combinations) must aggregate $50,000 or more invested during
the specified period from the date of the LOI or from a date within ninety (90)
days prior thereto, upon written request to Investor Services.  The sales
charge applicable to all amounts invested under the LOI is computed as if the
aggregate amount intended to be invested had been invested immediately.  If
such aggregate amount is not actually invested, the difference in the sales
charge actually paid and the sales charge payable had the LOI not been in
effect is due from the investor.  However, for the purchases actually made
within the specified period (either 13 or 48 months), the sales charge
applicable will not be higher than that which would have been applied
(including accumulations and combinations) had the LOI been for the amount
actually invested.

         The LOI authorizes Investor Services to hold in escrow sufficient
Class A shares (approximately 5% of the aggregate) to make up any difference in
sales charges on the amount intended to be invested and the amount actually
invested, until such investment is completed within the specified period, at
which time the escrow shares will be released.  If the total investment
specified in the LOI is not completed, the Class A shares held in escrow may be
redeemed and the proceeds used as required to pay such sales charge as may be
due.  By signing the LOI, the investor authorizes Investor Services to act as
his attorney-in-fact to redeem any escrow shares and adjust the sales charge,
if necessary.  A LOI does not constitute a binding commitment by an investor to
purchase, or by the Funds to sell, any additional shares and may be terminated
at any time.

DEFERRED SALES CHARGE ON CLASS B SHARES

         Investments in Class B shares are purchased at net asset value per
share without the imposition of a sales charge so that applicable Fund will
receive the full amount of the purchase payment.

         CONTINGENT DEFERRED SALES CHARGE.  Class B shares which are redeemed
within six years of purchase will be subject to a contingent deferred sales
charge ("CDSC") at the rates set forth in each Fund's Class A and Class B
Prospectus as a percentage of the dollar amount subject to the CDSC.  The
charge will be assessed on an amount equal to the lesser of the current market
value





                                       35
<PAGE>   154
or the original purchase cost of the Class B shares being redeemed.
Accordingly, no CDSC will be imposed on increases in account value above the
initial purchase prices, including Class B shares derived from reinvestment of
dividends or capital gains distributions.

         The amount of the CDSC, if any, will vary depending on the number of
years from the time of payment for the purchase of Class B shares until the
time of redemption of such shares.  Solely for purposes of determining the
number of years from the time of any payment for the purchases of shares, all
payments during a month will be aggregated and deemed to have been made on the
last day of the month.

         Proceeds from the CDSC are paid to John Hancock Funds and are used in
whole or in part by John Hancock Funds to defray its expenses related to
providing distribution-related services to the Funds in connection with the
sale of the Class B shares, such as the payment of compensation to select
Selling Brokers for selling Class B shares.  The combination of the CDSC and
the distribution and service fees facilitates the ability of the Funds to sell
the Class B shares without a sales charge being deducted at the time of the
purchase.  See each Fund's Class A and Class B Prospectus for additional
information regarding the CDSC.

SPECIAL REDEMPTIONS

         Although it would not normally do so, each Fund has the right to pay
the redemption price of shares of the Fund in whole or in part in portfolio
securities as prescribed the Trustees.  When the shareholder sells portfolio
securities received in this fashion, he would incur a brokerage charge.  Any
such securities would be valued for the purposes of making such payment at the
same value as used in determining net asset value.  The Funds have elected to
be governed by Rule 18f-1 under the 1940 Act, pursuant to which each Fund is
obligated to redeem shares solely in cash up to the lesser of $250,000 or 1% of
the net asset value of the applicable Fund during any 90 day period for any one
account.

ADDITIONAL SERVICES AND PROGRAMS

         EXCHANGE PRIVILEGE.  As described more fully in the Prospectuses, the
Funds permit exchanges of shares of any class of the Funds for shares of the
same class in any other John Hancock fund offering that class.

         SYSTEMATIC WITHDRAWAL PLAN.  As described briefly in the Class A and
Class B Prospectuses, the Funds permit the establishment of a Systematic
Withdrawal Plan.  Payments under this plan represent proceeds arising from the
redemption of Fund shares.  Since the redemption price of Fund shares may be
more or less than the shareholder's cost, depending upon the market value of
the securities owned by a Fund at the time of redemption, the distribution of
cash pursuant to this plan may result in realization of gain or loss for
purposes of Federal, state and local income taxes.  The maintenance of a
Systematic Withdrawal Plan concurrently with purchases of additional Class A or
Class B shares of a Fund could be disadvantageous to a shareholder because of
the initial sales charge payable on such purchases of Class A shares and





                                       36
<PAGE>   155
the CDSC imposed on redemptions of Class B shares and because redemptions are
taxable events.  Therefore, a shareholder should not purchase Fund shares at
the same time as a Systematic Withdrawal Plan is in effect.  The Funds reserve
the right to modify or discontinue the Systematic Withdrawal Plan of any
shareholder on 30 days' prior written notice to such shareholder, or to
discontinue the availability of such plan in the future.  The shareholder may
terminate the plan at any time by giving proper notice to Investor Services.

         MONTHLY AUTOMATIC ACCUMULATION PROGRAM ("MAAP").  This program is
explained fully in each Fund's Class A and Class B Prospectus and the Account
Privileges Application.  The program, as it relates to automatic investment
checks, is subject to the following conditions:

         The investments will be drawn on or about the day of the month
indicated.

         The privilege of making investments through the Monthly Automatic
Accumulation Program may be revoked by Investor Services without prior notice
if any investment is not honored by the shareholder's bank.  The bank shall be
under no obligation to notify the shareholder as to the non-payment of any
check.

         The program may be discontinued by the shareholder either by calling
Investor Services or upon written notice to Investor Services which is received
at least five (5) business days prior to the due date of any investment.

         REINVESTMENT PRIVILEGE.  A shareholder who has redeemed Fund shares
may, within 120 days after the date of redemption, reinvest without payment of
a sales charge any part of the redemption proceeds in shares of the same class
of that Fund or another John Hancock mutual fund, subject to the minimum
investment limit in that fund.  The proceeds from the redemption of Class A
shares may be reinvested at net asset value without paying a sales charge in
Class A shares of the Funds or in Class A shares of another John Hancock mutual
fund.  If a CDSC was paid upon a redemption, a shareholder may reinvest the
proceeds from that redemption at net asset value in additional shares of the
class from which the redemption was made.  The shareholder's account will be
credited with the amount of any CDSC charged upon the prior redemption and the
new shares will continue to be subject to the CDSC.  The holding period of the
shares acquired through reinvestment will, for purposes of computing the CDSC
payable upon a subsequent redemption, include the holding period of the
redeemed shares.  The Funds may modify or terminate the reinvestment privilege
at any time.

         A redemption or exchange of Fund shares is a taxable transaction for
Federal income tax purposes even if the reinvestment privilege is exercised,
and any gain or loss realized by a shareholder on the redemption or other
disposition of Fund shares will be treated for tax purposes as described under
the caption "Tax Status."

DESCRIPTION OF THE TRUST'S SHARES

         Ownership in the Funds is represented by transferable shares of
beneficial interest.  The Declaration of Trust permits the Trustees to create
an unlimited number of series and classes of shares of the Trust and, with
respect to each series and class, to issue an unlimited number of full or
fractional shares and to divide or combine the shares into a greater or lesser
number of shares without thereby changing the proportionate beneficial
interests of the series.

         Each share of each series or class of the Trust represents an equal
proportionate interest with each other in that series or class, none having
priority or preference over other shares of the same series or class.  The
interest of investors in the various series or classes of the Trust is separate
and distinct.  All consideration received for the sales of shares of a
particular series or class of the Trust, all assets in which such consideration
is invested and all income, earnings and profits derived from such investments
will be allocated to and belong to that series or class.  As such, each such
share is entitled to dividends and distributions out of the net income
belonging to that series or class as declared by the Board of Trustees.  Shares
of the Trust have a par value of $0.01 per share.  The assets of each series
are segregated on the Trust's books and are charged with the liabilities of
that series and with a share of the Trust's general liabilities.  The Board of
Trustees determines those assets and liabilities deemed to be general assets or
liabilities of the Trust, and these items are allocated among each series in
proportion to the relative total net assets of each series.  In the unlikely
event that the liabilities allocable to a series exceed the assets of that
series, all or a portion of such liabilities may have to be borne by the other
series.

         Pursuant to the Declaration of Trust, the Trustees have established
six series of shares, including the Funds, and may authorize the creation of
additional series of shares (the proceeds of which would be invested in
separate, independently managed portfolios) and additional classes within any
series (which would be used to distinguish among the rights of different
categories of shareholders, as might be required by future regulations or other
unforeseen circumstances).  The four other series of Trust are John Hancock
Adjustable U.S. Government Trust, John Hancock Investment Quality Bond Fund,
John Hancock Government Securities Trust and John Hancock Adjustable U.S.
Government Fund.  As of the date of this Statement of Additional Information,
the Trustees have authorized the issuance of two classes of shares of the
Funds, designated as Class A and Class B.  Class A and Class B shares of each
Fund represent an equal proportionate interest in the aggregate net asset
values attributable to that class of such Fund.  Holders of Class A shares and
Class B shares each have certain exclusive voting rights on matters relating to
the Class A Plan and the Class B Plan, respectively, of the applicable Fund.
The different classes of the Funds may bear different expenses relating to the
cost of holding shareholder meetings necessitated by the exclusive voting
rights of any class of shares.

         Dividends paid by the Funds, if any, with respect to each class of
shares will be calculated in the same manner, at the same time and on the same
day and will be in the same amount, except that (i) the distribution and
service fees relating to Class A and Class B shares relating to Class A and
Class B shares will be borne exclusively by that Class, (ii) Class B shares
will pay higher





                                       38
<PAGE>   157
distribution and service fees than Class A shares and (iii) each of Class A
shares and Class B shares will bear any class expenses properly allocable to
such class of shares, subject to the conditions set forth in a private letter
ruling that the Fund has received from the Internal Revenue Service relating to
its multiple-class structure.  Accordingly, the net asset value per share may
vary depending whether Class A shares or Class B shares are purchased.

         VOTING RIGHTS.  Shareholders are entitled to a full vote for each full
share held.  The Trustees themselves have the power to alter the number and the
terms of office of Trustees, and they may at any time lengthen their own terms
or make their terms of unlimited duration (subject to certain removal
procedures) and appoint their own successors, provided that at all times at
least a majority of the Trustees have been elected by shareholders.  The voting
rights of shareholders are not cumulative, so that holders of more than 50% of
the shares voting can, if they choose, elect all Trustees being voted upon,
while the holders of the remaining shares would be unable to elect any
Trustees.  Although the Trust need not hold annual meetings of shareholders,
the Trustees may call special meetings of shareholders for action by
shareholder vote as may be required by the 1940 Act or the Declaration of
Trust.  Also, a shareholder's meeting must be called if so requested in writing
by the holders of record of 10% or more of the outstanding shares of the Trust.
In addition, the Trustees may be removed by the action of the holders of record
of two-thirds or more of the outstanding shares.

         SHAREHOLDER LIABILITY.  The Declaration of Trust provides that no
Trustee, officer, employee or agent of the Trust is liable to the Trust or any
series or to a shareholder, nor is any Trustee, officer, employee or agent
liable to any third persons in connection with the affairs of the Trust, except
as such liability may arise from his or its own bad faith, willful misfeasance,
gross negligence or reckless disregard of his duties.  It also provides that
all third persons shall look solely to the particular series' property for
satisfaction of claims arising in connection with the affairs of that series.
With the exceptions stated, the Declaration of Trust provides that a Trustee,
officer, employee or agent is entitled to be indemnified against all liability
in connection with the affairs of the Trust.

         As a Massachusetts business trust, the Trust is not required to issue
share certificates.  The Trust shall continue without limitation of time
subject to the provisions in the Declaration of Trust concerning termination by
action of the shareholders.

         Under Massachusetts law, shareholders of a Massachusetts business
trust could, under certain circumstances, be held personally liable for acts or
obligations of the trust.  However, the Trust's Declaration of Trust contains
an express disclaimer of shareholder liability for acts, obligations and
affairs of the Trust.  The Declaration of Trust also provides for
indemnification out of the Trust's assets for all losses and expenses of any
shareholder held personally liable by reason of being or having been a
shareholder.  Liability is therefore limited to circumstances in which the
Trust itself would be unable to meet its obligations, and the possibility of
this occurrence is remote.

TAX STATUS

         Each Fund is treated as a separate entity for accounting and tax
purposes.  Each Fund has qualified and elected to be treated as a "regulated
investment company" under Subchapter M of the Internal Revenue Code of 1986, as
amended (the "Code"), and intends to continue to so qualify in the future.  As
such and by complying with the applicable provisions of the Code regarding the
sources of its income, the timing of its distributions, and the diversification
of its assets, each Fund will not be subject to Federal income tax on its net
income (including net short-term and long-term capital gain) which is
distributed to shareholders at least annually in accordance with the timing
requirements of the Code.

         Each Fund will be subject to a 4% non-deductible Federal excise tax on
certain amounts not distributed (and not treated as having been distributed) on
a timely basis in accordance with annual minimum distribution requirements.
Each Fund intends under normal circumstances to avoid liability for such tax by
satisfying such distribution requirements.

         Distributions from a Fund's current or accumulated earnings and
profits ("E&P"), as computed for Federal income tax purposes, will be taxable
as described in the Funds' Prospectuses whether taken in shares or in cash.
Distributions, if any, in excess of E&P will constitute a return of capital,
which will first reduce an investor's tax basis in Fund shares and thereafter
(after such basis is reduced to zero) will generally give rise to capital
gains.  Shareholders electing to receive distributions in the form of
additional shares will have a cost basis for Federal income tax purposes in
each share so received equal to the amount of cash they would have received had
they elected to receive the distributions in cash, divided by the number of
shares received.

         For each Fund, the amount of net short-term and long-term capital
gains, if any, in any given year will vary depending upon the Adviser's current
investment strategy and whether the Adviser believes it to be in the best
interest of the Fund to dispose of portfolio securities or enter into options
or futures transactions that will generate capital gains.  At the time of an
investor's purchase of Fund shares, a portion of the purchase price is often
attributable to realized or unrealized appreciation in the Fund's portfolio.
Consequently, subsequent distributions from such appreciation may be taxable to
such investor even if the net asset value of the investor's shares is, as a
result of the distributions, reduced below the investor's cost for such shares,
and the distributions in reality represent a return of a portion of the
purchase price.

         Upon a redemption of shares of a Fund (including by exercise of the
exchange privilege) a shareholder may realize a taxable gain or loss depending
upon his basis in his shares.  Such gain or loss will be treated as capital
gain or loss if the shares are capital assets in the shareholder's hands and
will be long-term or short-term, depending upon the shareholder's tax holding
period for the shares.  A sales charge paid in purchasing Class A shares of a
Fund cannot be taken into account for purposes of determining gain or loss on
the redemption or exchange of such shares within 90 days after their purchase
to the extent shares of the Fund or another John Hancock Fund are





                                       40
<PAGE>   159
subsequently acquired without payment of a sales charge pursuant to the
reinvestment or exchange privilege.  Such disregarded load will result in an
increase in the shareholder's tax basis in the shares subsequently acquired.
Also, any loss realized on a redemption or exchange may be disallowed to the
extent the shares disposed of are replaced with other shares of the same Fund
within a period of 61 days beginning 30 days before and ending 30 days after
the shares are disposed of, such as pursuant to the Dividend Reinvestment Plan.
In such a case, the basis of the shares acquired will be adjusted to reflect
the disallowed loss.  Any loss realized upon the redemption of shares with a
tax holding period of six months or less will be treated as a long-term capital
loss to the extent of any amounts treated as distributions of long-term capital
gain with respect to such shares.

         Although its present intention is to distribute all net short-term and
long-term capital gains, if any, each Fund reserves the right to retain and
reinvest all or any portion of its "net capital gain," which is the excess, as
computed for Federal income tax purposes, of net long-term capital gain over
net short-term capital loss in any year.  The Funds will not in any event
distribute net long-term capital gains realized in any year to the extent that
a capital loss is carried forward from prior years against such gain.  To the
extent such excess was retained and not exhausted by the carryforward of prior
years' capital losses, it would be subject to Federal income tax in the hands
of a Fund.  Each shareholder would be treated for Federal income tax purposes
as if such Fund had distributed to him on the last day of its taxable year his
pro rata share of such excess, and he had paid his pro rata share of the taxes
paid by the Fund and reinvested the remainder in the Fund.  Accordingly, each
shareholder would (a) include his pro rata share of such excess as long-term
capital gain income in his return for his taxable year in which the last day of
the Fund's taxable year falls, (b) be entitled either to a tax credit on his
return for, or to a refund of, his pro rata share of the taxes paid by the
Fund, and (c) be entitled to increase the adjusted tax basis for his shares in
the Fund by the difference between his pro rata share of such excess and his
pro rata share of such taxes.

         For Federal income tax purposes, each Fund is permitted to carry
forward a net capital loss in any year to offset its own net capital gains, if
any, during the eight years following the year of the loss.  To the extent
subsequent net capital gains are offset by such losses, they would not result
in Federal income tax liability to the applicable Fund and, as noted above,
would not be distributed as such to shareholders.  At December 31, 1994, the
Intermediate Government Fund had $735,389 of capital loss carryforwards
available to offset future net capital gains and such capital loss
carryforwards expire as follows:  $28,597 in 1997 and $706,792 in 2002.  At
December 31, 1994, the U.S. Government Fund had $53,533,889 of capital loss
carryforwards available to offset future net capital gains, and such capital
loss carryforwards expire as follows: $39,799,667 in 1996, $2,986,286 in 1997,
$5,412,804 in 1998, $653,763 in 1999, $2,152,064 in 2000 and $2,529,305 in
2002.

         Dividends, including capital gain distributions, paid by the Funds to
their corporate shareholders will not qualify for the corporate dividends
received deduction in their hands.





                                       41
<PAGE>   160
         Each Fund that invests in certain PIKs, zero coupon securities or
certain increasing rate securities (and, in general, any other securities with
original issue discount or with market discount if the Fund elects to include
market discount in income currently) must accrue income on such investments
prior to the receipt of the corresponding cash payments.  However, each Fund
must distribute, at least annually, all or substantially all of its net income,
including such accrued income, to shareholders to qualify as a regulated
investment company under the Code and avoid Federal income and excise taxes.
Therefore, a Fund may have to dispose of its portfolio securities under
disadvantageous circumstances to generate cash, or may have to leverage itself
by borrowing the cash, to satisfy distribution requirements.

         Different tax treatment, including penalties on certain excess
contributions and deferrals, certain pre-retirement and post-retirement
distributions and certain prohibited transactions, is accorded to accounts
maintained as qualified retirement plans.  Shareholders should consult their
tax advisers for more information.

         Each Fund may be required to account for its transactions in dollar
rolls in a manner that, under certain circumstances, may limit the extent of
its participation in such transactions.

         Limitations imposed by the Code on regulated investment companies like
the Funds may restrict each Fund's ability to enter into futures and options
forward transactions.
         Certain options and futures transactions undertaken by a Fund may
cause the Fund to recognize gains or losses from marking to market even though
its positions have not been sold or terminated and affect the character as
long-term or short-term and timing of some capital gains and losses realized by
the Fund.  Also, certain of a Fund's losses on its transactions involving
options or futures contracts and/or offsetting portfolio positions may be
deferred rather than being taken into account currently in calculating the
Fund's taxable income or gains.  Certain of the applicable tax rules may be
modified if a Fund is eligible and chooses to make one or more of certain tax
elections that may be available.  These transactions may therefore affect the
amount, timing and character of a Fund's distributions to shareholders.  The
Funds will take into account the special tax rules (including consideration of
available elections) applicable to options and futures contracts in order to
minimize any potential adverse tax consequences.

         The foregoing discussion relates solely to U.S. Federal income tax law
as applicable to U.S. persons (i.e., U.S. citizens or residents and U.S.
domestic corporations, partnerships, trusts or estates) subject to tax under
such law.  The discussion does not address special tax rules applicable to
certain classes of investors, such as tax-exempt entities, insurance companies,
and financial institutions.  Dividends, capital gain distributions, and
ownership of or gains realized on the redemption (including an exchange) of
Fund shares may also be subject to state and local taxes.  Shareholders should
consult their own tax advisers as to the Federal, state or local tax
consequences of ownership of shares of, and receipt of distributions from, the
Funds in their particular circumstances.

         Non-U.S. investors not engaged in a U.S. trade or business with which
their investment in a Fund is effectively connected will be subject to U.S.
Federal income tax treatment that is





                                       42
<PAGE>   161
different from that described above.  These investors may be subject to
nonresident alien withholding tax at the rate of 30% (or a lower rate under an
applicable tax treaty) on amounts treated as ordinary dividends from a Fund
and, unless an effective IRS Form W- 8 or authorized substitute is on file, to
31% backup withholding on certain other payments from the Fund.  Non-U.S.
investors should consult their tax advisers regarding such treatment and the
application of foreign taxes to an investment in either Fund.

         The Funds are not subject to Massachusetts corporate excise or
franchise taxes.  Provided that a Fund qualifies as a regulated investment
company under the Code, it will also not be required to pay any Massachusetts
income tax.

CALCULATION OF PERFORMANCE

         For the 30-day period ended March 31, 1995, the annualized yield of
Intermediate Government Fund's Class A shares was 4.65%, and for the 30-day
period ended March 31, 1995, the annualized yield of U.S. Government Fund's
Class A shares was 5.52%.  The average annual total returns of the Class A
shares of the Intermediate Government Fund for the one, five and life of the
Fund (November 3, 1986 (initial public offering) periods ended March 31, 1995
were (2.34)%, 5.63% and 6.23%, respectively.  The average annual total returns
of the Class A shares of the U.S. Government Fund for the one, five and life of
the Fund (inception) periods ended March 31, 1995 were (1.27)%, 6.63% and
6.38%, respectively.  The performance of the Intermediate Government Fund would
be lower if the Fund's former investment adviser did not voluntarily limit the
Fund's operating expenses.

         For the 30-day period ended March 31, 1995, the annualized yield of
Intermediate Government Fund's Class B shares was 5.08%, and for the 30-day
period ended March 31, 1995, the annualized yield of U.S. Government Fund's
Class B shares was 5.05%.  The average returns of the Class B shares of the
Intermediate Government Fund for life of the fund (September 30,1994,
inception) period ended March 31, 1995 was (1.27%).  The average annual total
return of the Class B shares of the U.S. Government Fund for the life of the
Fund (September 4, 1994, inception) was (0.72%).

         Each Fund's yield is computed by dividing net investment income per
share determined for a 30-day period by the maximum offering price per share
(which includes the full sales charge) on the last day of the period, according
to the following standard formula:

Yield  =  2      [ (a-b + 1 )6  -1]
                    ---
                     cd
Where:

        a=      dividends and interest earned during the period.

            b=  net expenses accrued during the period.



                                       43
<PAGE>   162
         c=      the average daily number of Fund shares outstanding during the
        period that would be entitled to receive dividends.

         d=      the maximum offering price per share on the last day of the
        period (NAV where applicable).

         Each Fund's total return is computed by finding the average annual
compounded rate of return over the 1-year, 5-year, and 10-year periods that
would equate the initial amount invested to the ending redeemable value
according to the following formula:

                                P (1 + T)n = ERV

         P=      a hypothetical initial investment of $1,000.

         T=      average annual total return

         n=      number of years

                  ERV = ending redeemable value of a hypothetical $1,000 
     investment made at the beginning of the designated periods or fraction 
     thereof.

         In the case of Class A shares or Class B shares, this calculation
assumes the maximum sales charge is included in the initial investment or the
CDSC is applied at the end of the period.  This calculation also assumes that
all dividends and distributions are reinvested at net asset value on the
reinvestment dates during the period.  The "distribution rate" is determined by
annualizing the result of dividing the declared dividends of a Fund during the
period stated by the maximum offering price or net asset value at the end of
the period.

         In addition to average annual total returns, a Fund may quote
unaveraged or cumulative total returns reflecting the simple change in value of
an investment over a stated period.  Cumulative total returns may be quoted as
a percentage or as a dollar amount, and may be calculated for a single
investment, a series of investments, and/or a series of redemptions, over any
time period.  Total returns may be quoted with or without taking a Fund's
maximum sales charge on Class A shares or the CDSC on Class B shares into
account.  Excluding a Fund's sales charge on Class A shares and the CDSC on
Class B shares from a total return calculation produces a higher total return
figure.

         From time to time, in reports and promotional literature, a Fund's
yield and total return will be compared to indices of mutual funds and bank
deposit vehicles such as Lipper Analytical Services, Inc.'s "Lipper -- Fixed
Income Fund Performance Analysis," a monthly publication which tracks net
assets, total return, and yield on approximately 1,700 fixed income mutual
funds in the United States.  Ibbotson and Associates, CDA Weisenberger and F.C.
Towers are also used for comparison purposes, as well as the Russell and
Wilshire Indices.

         Performance rankings and ratings reported periodically in national
financial publications such as MONEY Magazine, FORBES, BUSINESS WEEK, THE WALL
STREET JOURNAL, MICROPAL, INC., MORNINGSTAR, STANGER'S and BARRON'S, etc. will
also be utilized.

         The performance of a Fund is not fixed or guaranteed.  Performance
quotations should not be considered to be representations of performance of a
Fund for any period in the future.  The performance of a Fund is a function of
many factors including its earnings, expenses and number of outstanding shares.
Fluctuating market conditions; purchases, sales and maturities of portfolio
securities; sales and redemptions of shares of beneficial interest; and changes
in operating expenses are all examples of items that can increase or decrease a
Fund's performance.

         ADDITIONAL PERFORMANCE INFORMATION. The Funds may use comparative
performance information from certain industry research materials and/or
published in various periodicals.  The characteristics of the investments in
such comparisons may be different from those investments of a Fund's portfolio.
In addition, the formula used to calculate the performance statistics of such
investments may not be identical to the formula used by a Fund to calculate its
performance figures.  From time to time, advertisements or information for the
Funds may include a discussion of certain attributes or benefits to be derived
by an investment in a Fund.  Such advertisements or information may include
symbols, headlines or other material which highlight or summarize the
information discussed in more detail in the communication.

         The following publications, indices, averages and investments which
may be used in advertisements or information concerning the Funds for
dissemination to investors or shareholders, include but are not limited to:

         a.      Lipper-Mutual Fund Performance Analysis, Lipper-Fixed Income

       stars are based on a fund's historical risk/ reward ratio compared with
       similar funds for 3-, 5- and 10-year periods, including all sales
       charges and fees.  Morningstar, Inc., considered to be an expert in
       independent fund performance monitoring, has consented to the use of its
       ratings in Fund advertisements.

         In addition, advertisements and sales materials may contain
hypothetical performance examples for purposes of illustrating reinvestment (or
"compounding") of dividends at fixed rates of return or tax advantages to be
derived from deferring payment of federal (and state) income taxes (at maximum
rates) as compared to taxable investments assuming fixed rates of return.
Illustrations may also includes (1) hypothetical investments in various
retirement plans, such as IRAs, made by investors of various ages or (2)
comparisons to retirement plans funded by annuity or bank products.

         In assessing such comparisons, an investor should consider the
following factors:

         a.      It is generally either not possible or not practicable to
       invest in an average or index of certain investments.

         b.      Certificates of deposit issued by banks and other depository
       institutions represent an alternative income producing product.
       Certificates of deposit may offer fixed or variable interest rates and
       principal is guaranteed and may be insured.  Withdrawal of deposits
       prior to maturity will normally be subject to a penalty.  Rates offered
       by banks and other depository institutions are subject to change at any
       time specified by the issuing institution.

         c.      United States Treasury Bills, Notes or Bonds represent
       alternative income producing products.  Treasury obligations are issued
       in selected denominations.  Rates of Treasury obligations are fixed at
       the time of issuance and payment of principal and interest is backed by
       the full faith and credit of the United States government.  The market
       value of such instruments will generally fluctuate inversely with
       interest rates prior to maturity and will equal par value at maturity.

         Past performance is no guarantee of future results.  In addition,
investors are advised to consult their brokers or financial advisers when
considering an investment in a Fund based upon performance comparisons.

         The composition of the investments in such indexes and the
characteristics of such benchmark investments are not identical to, and in some
cases are very different from, those of a Fund's portfolio.  These indexes and
averages are generally unmanaged and the items included in the calculations of
such indexes and averages may not be identical to the formulas used by a Fund
to calculate its performance figures.

BROKERAGE ALLOCATION

         Decisions concerning the purchase and sale of portfolio securities and
the allocation of brokerage commissions are made by the Adviser and officers of
the Trust pursuant to recommendations made by an investment committee of the
Adviser, which consists of officers and directors of the Adviser and affiliates
and officers and Trustees who are interested persons of the Trust.  Orders for
purchases and sales of securities are placed in a manner which, in the opinion
of





                                       47
<PAGE>   166
the officers of the Trust, will offer the best price and market for the
execution of each such transaction.  Purchases from underwriters of portfolio
securities may include a commission or commissions paid by the issuer, and
transactions with dealers serving as market makers reflect a "spread."
Investments in debt securities are generally traded on a net basis through
dealers acting for their own account as principals and not as brokers; no
brokerage commissions are payable on such transactions.

         Each Fund's primary policy is to execute all purchases and sales of
portfolio instruments at the most favorable prices consistent with best
execution, considering all of the costs of the transaction including brokerage
commissions.  This policy governs the selection of brokers and dealers and the
market in which a transaction is executed.  Consistent with the foregoing
primary policy, the Rules of Fair Practice of the NASD and other policies that
the Trustees may determine, the Adviser may consider sales of shares of the
Funds as a factor in the selection of broker-dealers to execute the Funds'
portfolio transactions.

         To the extent consistent with the foregoing, the Funds will be
governed in the selection of brokers and dealers, and the negotiation of
brokerage commission rates and dealer spreads, by the reliability and quality
of the services, including primarily the availability and value of research
information and to a lesser extent statistical assistance furnished to the
Adviser of the Funds, and their value and expected contribution to the
performance of the Funds.  It is not possible to place a dollar value on
information and services to be received from brokers and dealers, since it is
only supplementary to the research efforts of the Adviser.  The receipt of
research information is not expected to reduce significantly the expenses of
the Adviser.  The research information and statistical assistance furnished by
brokers and dealers may benefit the Life Company or other advisory clients of
the Adviser, and conversely, brokerage commissions and spreads paid by other
advisory clients of the Adviser may result in research information and
statistical assistance beneficial to the Funds.  The Funds will make no
commitments to allocate portfolio transactions upon any prescribed basis.
While the Trust's officers will be primarily responsible for the allocation of
the Funds' brokerage business, their policies and practices in this regard must
be consistent with the foregoing and will at all times be subject to review by
the Trustees.  For the fiscal years ended March 31, 1995, 1994 and 1993, no
negotiated brokerage commissions were paid on portfolio transactions.

         As permitted by Section 28(e) of the Securities Exchange Act of 1934,
a Fund may pay to a broker which provides brokerage and research services to
the Fund an amount of disclosed commission in excess of the commission which
another broker would have charged for effecting that transaction.  This
practice is subject to a good faith determination by the Trustees that the
price is reasonable in light of the services provided and to policies that the
Trustees may adopt from time to time.  During the fiscal year ended March 31,
1995, the Funds did not pay commissions as compensation to any brokers for
research services such as industry, economic and company reviews and
evaluations of securities.

         The Adviser's indirect parent, the Life Company, is the indirect sole
shareholder of John Hancock Freedom Securities Corporation and its
subsidiaries, three of which, Tucker Anthony





                                       48
<PAGE>   167
Incorporated ("Tucker Anthony") John Hancock Distributors, Inc. ("John Hancock
Distributors") and Sutro & Company, Inc. ("Sutro"), are broker-dealers
("Affiliated Brokers").  Pursuant to procedures determined by the Trustees and
consistent with the above policy of obtaining best net results, the Fund may
execute portfolio transactions with or through Tucker Anthony or Sutro.  During
the year ended March 31, 1995, the Funds did not execute any portfolio
transactions with then affiliated brokers.

         Any of the Affiliated Brokers may act as broker for a Fund on exchange
transactions, subject, however, to the general policy of the Funds set forth
above and the procedures adopted by the Trustees pursuant to the 1940 Act.
Commissions paid to an Affiliated Broker must be at least as favorable as those
which the Trustees believe to be contemporaneously charged by other brokers in
connection with comparable transactions involving similar securities being
purchased or sold.  A transaction would not be placed with an Affiliated Broker
if the Fund would have to pay a commission rate less favorable than the
Affiliated Broker's contemporaneous charges for comparable transactions for its
other most favored, but unaffiliated, customers, except for accounts for which
the Affiliated Broker acts as a clearing broker for another brokerage firm, and
any customers of the Affiliated Broker not comparable to the Fund as determined
by a majority of the Trustees who are not interested persons (as defined in the
1940 Act) of the Trust, the Adviser or the Affiliated Brokers.  Because the
Adviser, which is affiliated with the Affiliated Brokers, has, as an investment
adviser to the Funds, the obligation to provide investment management services,
which includes elements of research and related investment skills, such
research and related skills will not be used by the Affiliated Brokers as a
basis for negotiating commissions at a rate higher than that determined in
accordance with the above criteria.  The Funds will not effect principal
transactions with Affiliated Brokers.  The Funds may, however, purchase
securities from other members of underwriting syndicates of which Tucker
Anthony, Sutro and John Hancock Distributors are members, but only in
accordance with the policy set forth above and procedures adopted and reviewed
periodically by the Trustees.

         For the fiscal years ended March 31, 1993, 1994 and 1995, U.S.
Government Fund paid to present and the former investment adviser brokerage
commissions in the amounts of $6,395, $5,612 and $0 respectively.  The former
investment adviser did not receive any brokerage commissions on portfolio
transactions effected on behalf of Intermediate Government Fund.

         Brokerage or other transaction costs of a Fund are generally
commensurate with the rate of portfolio activity.  The portfolio turnover rates
for the Funds for (a) the fiscal year ended March 31, 1995 and (b) the fiscal
year ended March 31, 1994 were:

         Intermediate Government Fund -    (a) 4% and (b) 89%.

         U.S. Government Fund -            (a) 438% and (b) 264%.

               John Hancock Funds - Intermediate Government Trust

NOTE A --
ACCOUNTING POLICIES

John Hancock Bond Fund, (the "Trust") is a diversified, open-end management
investment company, registered under the Investment Company Act of 1940. The
Trust consists of five series portfolios: John Hancock Intermediate Government
Trust (the "Fund"), John Hancock Investment Quality Bond Trust, John Hancock
Government Securities Trust, John Hancock U.S. Government Trust and John Hancock
Adjustable Government Trust. The Trustees may authorize the creation of
additional Funds from time to time to satisfy various investment objectives.
Effective December 22, 1994, the Trust and Funds changed names by replacing the
word Transamerica with John Hancock (See Note B).

        The Trustees have authorized the issuance of two classes of the Fund,
designated as Class A and Class B. The shares of each class represent an
interest in the same portfolio of investments of the Fund and have equal rights
to voting, redemption, dividends, and liquidation, except that certain expenses,
subject to the approval of the Trustees, may be applied differently to each
class of shares in accordance with current regulations of the Securities and
Exchange Commission and the Internal Revenue Service. Shareholders of a class
which bears distribution/service expenses under the terms of a distribution
plan, have exclusive voting rights regarding such distribution plan. Class A
Shares are subject to an initial sales charge of up to 4.75% and a 12b-1
distribution plan. Class B Shares are subject to a contingent deferred sales
charge and a separate 12b-1 distribution plan. On September 30, 1994, Class B
shares were sold to commence class activity. Significant accounting policies of
the Fund are as follows:

VALUATION OF INVESTMENTS Securities in the Fund's portfolio are valued on the
basis of market quotations, valuations provided by independent pricing services
or, at fair value as determined in good faith in accordance with procedures
approved by the Trustees. Short-term debt investments maturing within 60 days
are valued at amortized cost which approximates market value.

JOINT REPURCHASE AGREEMENT Pursuant to an exemptive order issued by the
Securities and Exchange Commission, the Fund, along with other registered
investment companies having a management contract with John Hancock Advisers,
Inc., a wholly-owned subsidiary of The Berkeley Financial Group, may participate
in a joint repurchase agreement transaction. Aggregate cash balances are
invested in one or more repurchase agreements, whose underlying securities are
obligations of the U.S. government and/or its agencies. The Fund's custodian
bank receives delivery of the underlying securities for the joint account on the
Fund's behalf. The Adviser is responsible for ensuring that the agreement is
fully collateralized at all times.

INVESTMENT TRANSACTIONS Investment transactions are recorded as of the date of
purchase, sale or maturity. Net realized gains and losses on sales of
investments are determined on the identified cost basis for both financial
reporting and federal income tax purposes.

DISCOUNT ON SECURITIES The Fund accretes discount from par value on securities
from either the date of issue or the date of purchase over the life of the
security, as required by the Internal Revenue Code.

FEDERAL INCOME TAXES The Fund's policy is to comply with the requirements of the
Internal Revenue Code that are applicable to regulated investment companies and
to distribute all of its taxable income, including any net realized gain on
investments, to its shareholders. Therefore, no federal income tax provision is
required. For federal income tax purposes, at December 31, 1994, the Fund has
approximately $735,000 of capital loss carryforwards available, to the extent
provided by regulations, to offset future net realized capital gains. If such
carryforward is used by the Fund, no capital gain distributions will be made.
The capital loss carryforwards will expire as follows: 1997 -- $29,000 and 2002
- -- $706,000. The Fund's tax year end is December 31.

DIVIDENDS, DISTRIBUTIONS AND INTEREST Interest income on investment securities
is recorded on the accrual basis.

        The Fund records all distributions to shareholders from net investment
income and realized gains on the ex-dividend date.  Such distributions are
determined in conformity with income tax

regulations, which may differ from generally accepted accounting principles.
Dividends paid by the Fund, if any, with respect to each class of shares will be
calculated in the same manner, at the same time and will be in the same amount,
except for the effect of expenses that may be applied differently to each class
as explained previously.

EXPENSES The majority of the expenses of the Trust are
directly identifiable to an individual Fund. Expenses which are not readily
identifiable to a specific Fund are allocated in such a manner as deemed
equitable, taking into consideration, among other things, the nature and type of
expense and the relative sizes of the Funds.

CLASS ALLOCATIONS Income, common expenses and realized and unrealized gains
(losses) are determined at the Fund level and allocated daily to each class of
shares based on the appropriate net assets of the respective classes.
Distribution/service fees if any, are calculated daily at the class level based
on the appropriated net assets of each class and the specific expense rate(s)
applicable to each class.

NOTE B --
MANAGEMENT FEE,
ADMINISTRATIVE SERVICES AND
TRANSACTIONS WITH AFFILIATES AND OTHERS

On December 22, 1994, John Hancock Advisers, Inc. (the "Adviser"), a wholly
owned subsidiary of The Berkeley Financial Group, became the investment adviser
for the Fund with approval of the Trustees and shareholders of the Fund. The
Fund's former investment manager was Transamerica Fund Management Company
("TFMC").

        Under the present investment management contract, the Fund pays a
monthly management fee to the Adviser for a continuous investment program
equivalent, to 0.50% of the Fund's average daily net asset value. This fee
structure is consistent with the former agreement with TFMC. For the period
ended March 31, 1995, the advisory fee earned by the Adviser and TFMC amounted
to $10,219 and $35,445, respectively, resulting in a total fee of $45,664.

        The Adviser and TFMC, for their respective periods, provided
administrative services to the Fund pursuant to an administrative service
agreement through January 16, 1995 on which day the agreement was terminated.

        In the event normal operating expenses of the Fund, exclusive of certain
expenses prescribed by state law, are in excess of the most restrictive state
limit where the Fund is registered to sell shares of beneficial interest, the
fee payable to the Adviser will be reduced to the extent of such excess and the
Adviser will make additional arrangements necessary to eliminate any remaining
excess expenses. The current limits are 2.5% of the first $30,000,000 of the
Fund's average daily net asset value, 2.0% of the next $70,000,000 and 1.5% of
the remaining average daily net asset value.

        The Adviser and TFMC, for their respective periods, voluntarily agreed
to limit the Fund's expenses further to the extent required to prevent expenses
from exceeding 1.30% of the Fund's average daily net asset value. Accordingly,
for the period ended March 31, 1995, the reduction to the Adviser's and TFMC's
fees, collectively with any amounts not borne by the Fund by virtue of the most
restrictive state expense limit, amounted to $10,143 and $28,364 respectively,
resulting in a total reduction of $38,507. The voluntary waiver may be
discontinued at any time.

        On December 22, 1994 John Hancock Funds, Inc. ("JH Funds"), a
wholly-owned subsidiary of the Adviser, became the principal underwriter of the
Fund. Prior to this date, Transamerica Fund Distributors, Inc. ("TFD") served as
the principal underwriter and distributor of the Fund. For the period ended
March 31, 1995, JH Funds and TFD received net sales charges of $34,289 with
regard to sales of Class A shares. Out of this amount, $3,185 was retained and
used for printing prospectuses, advertising, sales literature and other
purposes, and $31,104 was paid as sales commissions to unrelated broker-dealers.

        Class B shares which are redeemed within six years of purchase will be
subject to a contingent deferred sales charge ("CDSC") at declining rates
beginning at 5.0% of the lesser of the current market value at the time of
redemption or the original purchase cost of the shares being redeemed. Proceeds
from the CDSC are paid to JH Funds, formerly TFD, and are used in whole or in
part to defray its


                                       13

                         NOTES TO FINANCIAL STATEMENTS

expenses related to providing distribution related services to the Fund in
connection with the sale of Class B shares. For the period ended March 31, 1995,
there were no contingent deferred sales charges.

        In addition, to compensate JH Funds, for the services it provides as
distributor of shares of the Fund, the Fund has adopted a Distribution Plan with
respect to Class A and Class B pursuant to Rule 12b-1 under the Investment
Company Act of 1940. Accordingly, the Fund will make payments for distribution
and service expenses which in total will not exceed on an annual basis 0.25% of
the Fund's average daily net assets attributable to Class A shares and 1.00% of
the Fund's average daily net assets attributable to Class B shares, to reimburse
for its distribution/service costs. Up to a maximum of 0.25% of such payments
may be service fees as defined by the amended Rules of Fair Practice of the
National Association of Securities Dealers which became effective July 7, 1993.
Under the amended Rules of Fair Practice, curtailment of a portion of the Fund's
12b-1 payments could occur under certain circumstances. This fee structure and
plan is similar to the former arrangement with TFD.

        The Board of Trustees approved a shareholder servicing agreement between
the Fund and John Hancock Investor Services Corporation ("Investor Services"), a
wholly-owned subsidiary of The Berkeley Financial Group, for the period between
December 22, 1994 and May 12, 1995, inclusive under which Investor Services
processed telephone transactions on behalf of the Fund. As of May 15, 1995, the
Fund entered into a full service transfer agent agreement with Investor
Services. Prior to this date The Shareholder Services Group was the transfer
agent. The Fund will pay Investor Services a fee based on transaction volume and
number of shareholder accounts.

        A partner with Baker & Botts was an officer of the Trust until December
22, 1994. During the period ended March 31, 1995, legal fees paid to Baker &
Botts amounted to $651.

        Mr. Edward J. Boudreau, Jr. is a director and officer of the Adviser and
its affiliates as well as Trustee of the Fund. The compensation of unaffiliated
Trustees is borne by the Fund. Effective with the fees paid for 1995, the
unaffiliated Trustees may elect to defer their receipt of this compensation
under the John Hancock Group of Funds Deferred Compensation Plan. The Fund will
make investments into other John Hancock Funds, as applicable, to cover its
liability with regard to the deferred compensation. Investments to cover the
Fund's deferred compensation liability will be recorded on the Fund's books as
other assets. The deferred compensation liability will be marked to market on a
periodic basis and income earned by the investment will be recorded on the
Fund's books.

        The Fund has an independent advisory board composed of certain members
of the former Transamerica Board of Trustees who provide advice to the current
Trustees in order to facilitate a smooth management transition for which the
Fund pays the advisory board and its counsel a fee.

NOTE C --
INVESTMENT TRANSACTIONS

Purchases and proceeds from sales of securities, other than short-term
obligations, during the period ended March 31, 1995 aggregated $5,545,730 and
$6,675,284, respectively.

        The cost of investments owned at March 31, 1995 for Federal income tax
purposes was $8,424,964. Gross unrealized appreciation and depreciation of
investments aggregated none and $248,059, respectively, resulting in net
unrealized depreciation of $248,059.

               John Hancock Funds - Intermediate Government Trust


REPORT OF ERNST & YOUNG, INDEPENDENT AUDITORS

To the Board of Trustees and Shareholders of
John Hancock Bond Fund --
John Hancock Intermediate Government Trust

We have audited the accompanying statement of assets and liabilities, including
the schedule of investments, of the John Hancock Intermediate Government Trust
(formerly Transamerica Intermediate Government Trust) (the "Fund"), one of the
portfolios constituting John Hancock Bond Fund (formerly Transamerica Bond Fund)
(the "Trust"), as of March 31, 1995, and the related statement of operations for
the year then ended, the statements of changes in net assets for each of the two
years in the period then ended, and the financial highlights for each of the
five years in the period then ended. These financial statements and financial
highlights are the responsibility of the Fund's management. Our responsibility
is to express an opinion on these financial statements and financial highlights
based on our audits.

        We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements and financial
highlights are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. Our procedures included confirmation of securities owned as of March
31, 1995, by correspondence with the custodian. An audit also includes assessing
the accounting principles used and significant estimates made by management, as
well as evaluating the overall financial statement presentation. We believe that
our audits provide a reasonable basis for our opinion.

        In our opinion, the financial statements and financial highlights
referred to above present fairly, in all material respects, the financial
position of the John Hancock Intermediate Government Trust portfolio of John
Hancock Bond Fund at March 31, 1995, the results of its operations for the year
then ended, the changes in its net assets for each of the two years in the
period then ended, and the financial highlights for each of the five years in
the period then ended, in conformity with generally accepted accounting
principles.
