Dear Fellow Shareholder:

I am writing to ask for your vote on an  important  matter that will affect your
investment in the John Hancock Limited-Term Government Fund.

You may be aware that in  addition to your Fund,  John  Hancock  Funds  offers a
similar  U.S.  government  income  fund  called  the John  Hancock  Intermediate
Maturity  Government  Fund.  The  Intermediate  Maturity  Government  Fund seeks
current  income  consistent  with  preservation  of capital and  maintenance  of
liquidity,  by  investing  primarily  in  bonds  issued  by  the  United  States
government and its agencies.

   
After careful  consideration,  your Fund's Trustees have unanimously agreed that
merging your Fund into the John Hancock  Intermediate  Maturity  Government Fund
will offer you a similar investment  objective and strategy with lower operating
expenses.  This proposed  merger is detailed in the enclosed proxy statement and
summarized in the  questions  and answers on the  following  page. I suggest you
read both thoroughly prior to voting.
    

Your Vote Makes a Difference!
No matter what the size of your investment may be, your vote is critical. I urge
you to review  the  enclosed  materials  and to  complete,  sign and  return the
enclosed proxy ballot to us  immediately.  Your prompt  response will help avoid
the need for additional  mailings at your Fund's expense.  For your convenience,
we have provided a postage-paid envelope.

   
If you have any questions or need  additional  information,  please contact your
investment   professional  or  call  your  Customer  Service  Representative  at
1-800-225-5291,  Monday through  Friday between 8:00 A.M. and 8:00 P.M.  Eastern
Time. I thank you for your prompt vote on this matter.
    



                                                     Sincerely,

                                                     /s/ Edward J. Boudreau, Jr.

                                                     Edward J. Boudreau, Jr.
                                                     Chairman and CEO

Q: What are the benefits of merging the  Limited-Term  Government  Fund into the
Intermediate Maturity Government Fund?

A: Offering two similar U.S. government income funds has made it harder for both
your Fund and the  Intermediate  Maturity  Government  Fund to raise  assets and
reduce  expenses.  Your  Trustees  firmly  believe this merger will allow you to
continue  investing for current income with  preservation  of capital at a lower
expense.

   
The Intermediate  Maturity  Government Fund's larger asset base after the merger
are  expected  to allow for  lower  operating  expenses  than your Fund has now.
Following  the  merger,  annual  fees  are  projected  to be 1.10%  for  Class A
shareholders,  down from 1.33%,  and 1.85% for Class B  shareholders,  down from
2.03%.  These  projected lower expenses should keep more of your money invested,
which often helps to bolster an investment's total return over time.
    

Q: How does the Intermediate  Maturity  Government  Fund's strategy compare with
that of the Limited-Term Government Fund?

   
A: The  Intermediate  Maturity  Government  Fund  seeks a high  level of current
income  consistent  with  preservation  of capital and maintenance of liquidity.
Your Fund seeks current  income and security of  principal.  Both funds focus on
bonds  with  maturities  of up to ten years  issued by the U.S.  government  its
agencies. Your Fund is slightly more conservative,  however, investing in short-
to medium-term  securities,  while the Intermediate  Maturity  Government Fund's
emphasis is on medium-term  maturities ranging from three to ten years. Although
longer-term   bonds  can  be  more  sensitive  to  interest  rate  changes  than
shorter-term  bonds,  investing in  medium-term  bonds  allows the  Intermediate
Maturity  Government  Fund to seek higher current  income than your Fund,  while
still focusing on principal security.
    

<PAGE>

Q: How has the Intermediate Maturity Government Fund performed?

   
A: Although past performance does not necessarily  guarantee future results, the
Intermediate  Maturity  Government  Fund has been a steady  performer  since its
inception on December 31,  1991.  The Fund's Class A shares have posted  average
annual  total  returns of 4.15%  over the past  year,  4.69% over the past three
years,  3.96% over the past five years and 4.50% since inception on December 31,
1991 at public  offering  price as of June 30, 1997.  For the same time periods,
the Fund's Class B shares have posted  average  annual  total  returns of 3.64%,
4.47%,  3.91%  and 4.39%  respectively.*  To review  the  Intermediate  Maturity
Government  Fund in more detail,  please refer to the John Hancock  Income Funds
prospectus and the Intermediate  Maturity  Government  Fund's most recent annual
and semiannual reports, all of which are enclosed.
    

Q: How do I vote?

A: Most  shareholders  typically vote by  completing,  signing and returning the
enclosed proxy card using the postage-paid  envelope provided.  If you prefer to
vote in person, you are cordially invited to attend a meeting of shareholders of
your  Fund,  which will be held at 9:00 A.M.  on  November  12,  1997 at our 101
Huntington Avenue  headquarters in Boston,  Massachusetts.  If you vote now, you
will help avoid further solicitations at your Fund's expense.

Q: How will the merger happen?

   
A: If the merger is approved,  your Limited-Term  Government Fund shares will be
converted to Intermediate  Maturity Government Fund shares, using the Funds' net
asset value share prices,  excluding  sales charges,  at the close of trading on
December 5, 1997. This conversion will not affect the total dollar value of your
investment.
    

Q: Will the merger have tax consequences?

A:  Although  taxable  dividends  and  capital  gains  will be paid prior to the
merger,  the  merger  itself  is a  non-taxable  event  and  does not need to be
reported on your 1997 tax return.

*Performance  figures  assume all  distributions  are  reinvested  and reflect a
maximum  sales  charge  on Class A shares  of 3% and the  applicable  contingent
deferred  sales charge on Class B shares.  The CDSC  declines  annually  between
years 1-4  according to the  following  schedule:  3, 3, 2, 1% . No sales charge
will be assessed  after the sixth year.  The return and  principal  value of any
mutual fund  investment will fluctuate,  so that shares,  when redeemed,  may be
worth more or less than their original cost.

month period ended May 31, 1997, adjusted to reflect any changes.  (The expenses
for  Limited-Term  Government Fund were annualized using the actual expenses for

examples are for comparison purposes only and are not a representation of either
fund's actual expenses or returns, either past or future.

The Reorganization

o        The reorganization is scheduled to occur at 5:00 p.m., Eastern time, on
         December 5, 1997,  but may occur on any later date before June 1, 1998.
         Your fund will  transfer  all of its  assets to  Intermediate  Maturity
         Government Fund. Intermediate Maturity Government Fund will assume your
         fund's liabilities.  The net asset value of both funds will be computed
         as of 5:00 p.m., Eastern time, on the reorganization date.

                                       14

<PAGE>

o        Intermediate  Maturity  Government Fund will issue Class A shares in an
         amount  equal to the  aggregate  net asset value of your fund's Class A
         shares.  These shares will  immediately  be  distributed to your fund's
         Class  A   shareholders   in  proportion  to  their   holdings  on  the
         reorganization  date. As a result,  Class A  shareholders  of your fund
         will end up as Class A shareholders of Intermediate Maturity Government
         Fund.

o        Intermediate  Maturity  Government Fund will issue Class B shares in an
         amount  equal to the  aggregate  net asset value of your fund's Class B
         shares.  These shares will  immediately  be  distributed to your fund's
         Class  B   shareholders   in  proportion  to  their   holdings  on  the
         reorganization  date. As a result,  Class B  shareholders  of your fund
         will end up as Class B shareholders of Intermediate Maturity Government
         Fund.

o        After the reorganization is over, your fund will be terminated.

o        The reorganization will be tax-free and will not take place unless both
         funds receive a satisfactory opinion concerning the tax consequences of
         the reorganization from Hale and Dorr LLP, counsel to the funds.

Other Consequences of the  Reorganization.  Each fund pays monthly advisory fees
equal to the following annual percentage of average daily net assets:

- --------------------------- --------------------------- ------------------------
        Fund Asset                 Limited-Term               Intermediate
       Breakpoints                  Government                  Maturity
- --------------------------- --------------------------- ------------------------
First $250 million                    0.60%                       0.40%
- --------------------------- --------------------------- ------------------------
Next $250 million                     0.55%                       0.40%
- --------------------------- --------------------------- ------------------------
Over $500 million                     0.50%                       0.40%
- --------------------------- --------------------------- ------------------------

Thus, at all asset levels, the advisory fee rates paid by Intermediate  Maturity
Government Fund are lower than the rates paid by your fund.

In addition,  Intermediate Maturity Government Fund's current annual Class A and
Class B expense ratios (equal to 1.35% and 2.10%,  respectively,  of average net
assets) are only slightly  higher than your fund's current expense ratios (equal
to 1.33% 2.03%, respectively,  of average net assets). If the reorganization had
occurred on May 31,  1997,  Intermediate  Maturity  Government  Fund's pro forma
Class A and Class B expense ratios (equal to 1.10% and 1.85%,  respectively,  of
average  net  assets)  would have been lower than your  fund's  current  expense
ratios.

                                INVESTMENT RISKS

The funds are  exposed to various  risks that could cause  shareholders  to lose
money on their  investments in the funds. The following table indicates that the
risks affecting each fund are similar:

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

Risks of debt       The value of the funds' portfolios will change in response
securities          to movements of the bond market.  As with any fund that
                    invests  primarily  in debt  securities  a rise in  interest
                    rates  typically  causes  the value of debt  securities  and
                    hence  the  value of the fund to  fall.  A fall in  interest
                    rates typically causes the value of debt securities to rise.
                    The debt  securities  held by the funds are  subject  to the
                    risk that the issuer of a security will default or otherwise
                    fail to meet its obligations.

- ------------------- ------------------------------------------------------------
Risks of            The funds' investments in restricted and illiquid
restricted and      securities may be difficult or impossible to sell at a
illiquid            desirable time or a fair price.  Restricted and illiquid
securities          securities also present a greater risk of inaccurate
                    valuation.
- ------------------- ------------------------------------------------------------
Risks of            Unleveraged derivative instruments involve the risk that a
unleveraged         rise in interest rates will cause the value of the
derivative          instrument to fall.  A fall in interest rates will

including           These instrument are also subject to the risk that the
asset-back and      issuer will default or otherwise fail to meet its
mortgage-back       obligations.  In addition, mortgage-backed securities are
securities and      subject to the risk that the life of the security will be
rights and          extended beyond its expected prepayment time.  This
warrants            typically occurs during periods of rising interest rates
                    and often reduces the security's value.  During periods of
                    falling interest rates unanticipated prepayments may occur
                    which also reduces the security's value.  With respect to
                    rights and warrants, their value will change in response to
                    market movements.

                       PROPOSAL TO APPROVE THE AGREEMENT
                           AND PLAN OF REORGANIZATION

Description of Reorganization

The shareholders of your fund are being asked to approve an Agreement and Plan
of Reorganization, a copy of which is attached as Exhibit A.  The Agreement
provides for a reorganization on the following terms:

o        The reorganization is scheduled to occur at 5:00 p.m., Eastern time,
         on December 5, 1997, but may occur on any later date before June 1,
         1998.  Your fund will transfer all of its assets to Intermediate
         Maturity Government Fund and Intermediate Maturity Government Fund
         will assume all of your fund's liabilities.  This will result in the
         addition of your fund's assets to Intermediate Maturity Government

                                       18

<PAGE>

         Fund's portfolio.  The net asset value of both funds will be computed
         as of 5:00 p.m., Eastern time, on the reorganization date.

o        Intermediate Maturity Government Fund will issue to your fund Class A
         shares in an amount equal to the aggregate net asset value of your
         fund's Class A shares.  As part of the liquidation of your fund,
         these shares will immediately be distributed to Class A shareholders
         of record of your fund in proportion to their holdings on the
         reorganization date.  As a result, Class A shareholders of your fund
         will end up as Class A shareholders of Intermediate Maturity
         Government Fund.

o        Intermediate Maturity Government Fund will issue to your fund Class B
         shares in an amount equal to the aggregate net asset value of your
         fund's Class B shares.  As part of the liquidation of your fund,
         these shares will immediately be distributed to Class B shareholders
         of record of your fund in proportion to their holdings on the
         reorganization date.  As a result, Class B shareholders of your fund
         will end up as Class B shareholders of Intermediate Maturity
         Government Fund.

o        After the reorganization is over, the existence of your fund will be
         terminated.

Reasons for the Proposed Reorganization

The board of trustees of your fund  believes  that the  proposed  reorganization
will be advantageous to the shareholders of your fund for several  reasons.  The
board of trustees  considered the following matters,  among others, in approving
the proposal.

First,  that it is not  advantageous  to operate and market your fund separately
from Intermediate  Maturity Government Fund because their investment  objectives
and policies are substantially  similar. By being offered  simultaneously,  each
fund hinders the other fund's potential for asset growth.

Second,  that  shareholders  may be  better  served by a fund  offering  greater
diversification.  To the extent that  combining  the funds' assets into a single
portfolio creates a larger asset base,  Intermediate  Maturity Government Fund's
investment   portfolio   can   achieve   greater   diversification   after   the
reorganization   than  is   currently   possible   for  either   fund.   Greater
diversification is expected to benefit the shareholders of both funds because it

                                       19

<PAGE>

may reduce the negative effect that the adverse  performance of any one security
may have on the performance of the entire portfolio.

Third,  that the  Intermediate  Maturity  Government Fund shares received in the
reorganization will provide your fund's shareholders with substantially the same
investment  advantages as they currently have at a comparable level of risk. The
board of trustees also considered the performance history of each fund.

Fourth, that a combined fund offers economies of scale that are expected to lead
to better control over expenses than is possible for your fund. Both funds incur
substantial costs for accounting,  legal,  transfer agency services,  insurance,
and  custodial  and  administrative  services.  The  trustees  expect  that  the
reorganization  will result in a decrease  in the  expenses  currently  borne by
Limited-Term Government Fund shareholders.

Fifth, that Intermediate Maturity Government Fund affords its portfolio managers
greater  flexibility to pursue a broader range of investment  opportunities than
does  your  fund.  While  past  performances   cannot  predict  future  results,
Intermediate  Maturity Government Fund has performed better than your fund since
Intermediate  Maturity Government Fund adopted more flexible investment policies
on September 22, 1995.

The board of trustees of Intermediate  Maturity  Government Fund considered that
the reorganization  presents an excellent  opportunity for Intermediate Maturity
Government  Fund to acquire  investment  assets  without the  obligation  to pay
commissions or other  transaction  costs that are normally  associated  with the
purchase  of  securities.  This  opportunity  provides  an  economic  benefit to
Intermediate Maturity Government Fund and its shareholders.

The boards of  trustees of both funds also  considered  that the adviser and the
funds'  distributor,  John  Hancock  Funds,  Inc.,  will also  benefit  from the
reorganization.  For  example,  the adviser  might  realize  time savings from a
consolidated  portfolio  management  effort and from the need to  prepare  fewer
reports and  regulatory  filings as well as prospectus  disclosure  for one fund
instead of two.  The  trustees  believe,  however,  that these  savings will not
amount to a significant economic benefit.

Comparative Fees and Expense Ratios.  As discussed above in the Summary,  at all
asset  levels the advisory fee rates paid by  Intermediate  Maturity  Government
Fund are lower than the advisory rates paid by your fund.

                                       20

<PAGE>

Intermediate  Maturity  Government  Fund's  current  annual  Class A and Class B
expense ratios (equal to 1.35% and 2.10%,  respectively,  of average net assets)
are only slightly higher than your fund's current expense ratios (equal to 1.33%
and 2.03%,  respectively,  of average net  assets).  If the  reorganization  had
occurred on May 31,  1997,  Intermediate  Maturity  Government  Fund's pro forma
Class A and Class B expense ratios (equal to 1.10% and 1.85%,  respectively,  of
average  net  assets)  would have been lower than your  fund's  current  expense
ratios.

Comparative Performance.  The trustees also took into consideration the relative
performance of your fund and Intermediate  Maturity Government Fund. As shown in
the table below,  your fund has had better  performance  for some periods  while
Intermediate  Maturity  Government Fund has had better  performance for the most
recent periods.

Although the Intermediate Maturity Government Fund's 5 and 10 year total returns
trail those of your fund, these figures reflect Intermediate Maturity Government
Fund operating under more restrictive  investment policies.  Since adopting more
flexible  investment policies on September 22, 1995,  Intermediate  Maturity has
outperformed  your  fund.  In  fact,  the  gap  between  Intermediate   Maturity
Government Fund's  performance and your fund's  performance has widened over the
last three years. For the three year period, the difference between Intermediate
Maturity  Government  Fund's  total return and your fund's total return is 0.22%
for Class A shares. For the one year period,  that difference has risen to 1.76%
for Class A shares.

Unreimbursed Distribution and Shareholder Service Expenses

The boards of trustees of your fund and  Intermediate  Maturity  Government Fund
have determined that, if the reorganization  occurs,  unreimbursed  distribution
and  shareholder  service  expenses  incurred under your fund's Rule 12b-1 Plans
will be reimbursable expenses under Intermediate Maturity Government Fund's Rule
12b-1 Plans.  The maximum amount payable  annually under  Intermediate  Maturity
Government  Fund's Rule 12b-1 Plans (0.25% and 1.00% of average daily net assets
attributable  to Class A  shares  and  Class B  shares,  respectively)  will not
increase.

The following table shows the actual and pro forma unreimbursed distribution and
shareholder  service  expenses  of both  classes  of your fund and  Intermediate
Maturity  Government  Fund.  The table  shows  both the  dollar  amount of these
expenses  and the  percentage  of each  class'  average  net  assets  that  they
represent.

Actual expenses as of May 31,    $255,361      $185,390     $58,172     $403,120
1997                               0.16%        1.77%        0.26%        6.25%

Pro forma combined expenses as                             $313,533     $588,510

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


Thus,  if the  reorganization  had taken  place on May 31,  1997,  the pro forma
combined  unreimbursed expenses of Intermediate Maturity Government Fund's Class
A and  Class B shares  would  have been  higher  than if no  reorganization  had
occurred.  Intermediate  Maturity  Government  Fund's  assumption of your fund's
unreimbursed Rule 12b-1 expenses will have no immediate effect upon the payments
made under  Intermediate  Maturity  Government  Fund's Rule 12b-1  Plans.  These
payments  will  continue  to be 0.25% and  1.00% of  average  daily  net  assets
attributable to Class A and Class B shares, respectively.

John  Hancock  Funds,  Inc.  hopes  to  recover  unreimbursed  distribution  and
shareholder service expenses for Class B shares over an extended period of time.
However,  if Intermediate  Maturity  Government  Fund's board terminates  either
class' Rule 12b-1 Plan,  that class will not be  obligated  to  reimburse  these
distribution and shareholder service expenses  Accordingly,  until they are paid

                                       22

<PAGE>

or accrued,  unreimbursed  distribution and shareholder  service expenses do not
and will not appear as an expense or liability in the  financial  statements  of
either fund.  In addition,  unreimbursed  expenses are not reflected in a fund's
net asset value or the formula for calculating Rule 12b-1 payments. The staff of
the SEC has not  approved  or  disapproved  the  treatment  of the  unreimbursed
distribution and shareholder service expenses described in this proxy statement

Tax Status of the Reorganization

The reorganization will be tax-free for federal income tax purposes and will not
take place unless both funds receive a  satisfactory  opinion from Hale and Dorr
LLP, counsel to the funds, substantially to the effect that:

o        The reorganization  described above will be a  "reorganization"  within
         the meaning of Section  368(a)(1)(D)  of the  Internal  Revenue Code of
         1986 (the "Code"),  and each fund will be "a party to a reorganization"
         within the meaning of Section 368 of the Code;

o        No gain or loss will be  recognized  by your fund upon (1) the transfer
         of all of its  assets  to  Intermediate  Maturity  Government  Fund  as
         described  above or (2) the  distribution  by your fund of Intermediate
         Maturity Government Fund shares to your fund's shareholders;

o        No gain or loss will be recognized by Intermediate  Maturity Government
         Fund upon the receipt of your fund's  assets solely in exchange for the
         issuance  of  Intermediate  Maturity  Government  Fund  shares  and the
         assumption of all of your fund's  liabilities by Intermediate  Maturity
         Government Fund;

o        The basis of the assets of your fund acquired by Intermediate  Maturity
         Government  Fund will be the same as the  basis of those  assets in the
         hands of your fund immediately before the transfer;

o        The tax  holding  period  of the  assets  of your  fund in the hands of
         Intermediate  Maturity  Government  Fund will  include  your fund's tax
         holding period for those assets;

o        The  shareholders of your fund will not recognize gain or loss upon the
         exchange  of all  their  shares of your fund  solely  for  Intermediate
         Maturity Government Fund shares as part of the reorganization;

o        The basis of Intermediate  Maturity  Government Fund shares received by
         your fund's  shareholders in the reorganization will be the same as the
         basis of the shares of your fund surrendered in exchange; and

                                       23

<PAGE>

o        The tax holding period of the  Intermediate  Maturity  Government  Fund
         shares  received  by you will  include  the tax  holding  period of the
         shares of your fund  surrendered  in the  exchange,  provided  that the
         shares of your fund were held as capital  assets on the  reorganization
         date.

Additional Terms of Agreement and Plan of Reorganization

Surrender  of Share  Certificates.  Shareholders  of your fund whose  shares are
represented by one or more share certificates should,  before the reorganization
date, either surrender their certificates to your fund or deliver to your fund a
lost certificate affidavit, in the form and accompanied by the surety bonds that
your fund may require  (collectively,  an  "Affidavit").  On the  reorganization
date, all certificates that have not been surrendered will be canceled,  will no
longer evidence  ownership of your fund's shares and will evidence  ownership of
Intermediate  Maturity  Government Fund shares.  Shareholders  may not redeem or
transfer   Intermediate   Maturity   Government  Fund  shares  received  in  the
reorganization  until they have surrendered their  Limited-Term  Government Fund
share certificates or delivered an Affidavit.  Intermediate  Maturity Government
Fund will not issue share certificates in the reorganization.

Conditions  to  Closing  the  Reorganization.  The  obligation  of your  fund to
consummate  the  reorganization  is  subject  to  the  satisfaction  of  certain
conditions,  including the performance by Intermediate  Maturity Government Fund
of all its  obligations  under the  Agreement  and the receipt of all  consents,
orders and permits  necessary to consummate the  reorganization  (see Agreement,
paragraph 6).

The  obligation of  Intermediate  Maturity  Government  Fund to  consummate  the
reorganization is subject to the satisfaction of certain  conditions,  including
your fund's  performance  of all of its  obligations  under the  Agreement,  the
receipt of certain  documents  and financial  statements  from your fund and the
receipt  of all  consents,  orders  and  permits  necessary  to  consummate  the
reorganization (see Agreement, paragraph 7).

The  obligations  of both funds are subject to the approval of the  Agreement by
the necessary vote of the  outstanding  shares of your fund, in accordance  with
the  provisions  of your fund's  declaration  of trust and  by-laws.  The funds'
obligations  are also subject to the receipt of a favorable  opinion of Hale and
Dorr LLP as to the federal income tax consequences of the  reorganization.  (see
Agreement, paragraph 8).

                                       24

<PAGE>

Termination  of  Agreement.  The  board  of  trustees  of  either  your  fund or
Intermediate  Maturity  Government Fund may terminate the Agreement (even if the
shareholders  of your fund have  already  approved  it) at any time  before  the
reorganization   date,  if  that  board  believes  that   proceeding   with  the
reorganization would no longer be advisable.

Expenses of the Reorganization.  Intermediate  Maturity Government Fund and your
fund will each be responsible  for its own expenses  incurred in connection with
entering into and carrying out the provisions of the  Agreement,  whether or not
the  reorganization  occurs.  These  expenses are estimated to be  approximately
$180,024 in total.

                                 CAPITALIZATION

The  following  table sets forth the  capitalization  of each fund as of May 31,
1997,  and  the pro  forma  combined  capitalization  of  both  funds  as if the
reorganization  had occurred on such date. The table reflects pro forma exchange
ratios of approximately  0.892160 Class A Intermediate  Maturity Government Fund
shares  being  issued  for  each  Class A share of your  fund and  approximately
0.892160 Class B Intermediate  Maturity  Government Fund shares being issued for
each Class B share of your  fund.  If the  reorganization  is  consummated,  the
actual  exchange  ratios on the  reorganization  date may vary from the exchange
ratios indicated due to changes in the market value of the portfolio  securities
of both Intermediate Maturity Government Fund and your fund between May 31, 1997
and  the  reorganization  date,  changes  in the  amount  of  undistributed  net
investment  income  and net  realized  capital  gains of  Intermediate  Maturity
Government  Fund and your fund  during  that  period  resulting  from income and
distributions,  and changes in the accrued liabilities of Intermediate  Maturity
Government Fund and your fund during the same period.

It is  impossible  to  predict  how many  Class A shares  and  Class B shares of
Intermediate  Maturity Government Fund will actually be received and distributed
by your fund on the reorganization  date. The table should not be relied upon to
determine the amount of Intermediate  Maturity  Government Fund shares that will
actually be received and distributed.

                     BOARDS' EVALUATION AND RECOMMENDATION

For the reasons  described above, the board of trustees of your fund,  including
the  trustees  who are not  "interested  persons"  of either fund or the adviser
("independent  trustees"),  approved  the  reorganization.  In  particular,  the
trustees  determined that the  reorganization  was in the best interests of your
fund and that the interests of your fund's  shareholders would not be diluted as
a result of the reorganization. Similarly, the board of trustees of Intermediate
Maturity  Government  Fund,  including the  independent  trustees,  approved the
reorganization.  They also  determined that the  reorganization  was in the best
interests of  Intermediate  Maturity  Government  Fund and that the interests of
Intermediate  Maturity  Government Fund's shareholders would not be diluted as a
result of the reorganization.

- --------------------------------------------------------------------------------
The trustees of your fund recommend that the  shareholders of your fund vote for
the proposal to approve the agreement and plan of reorganization.
- --------------------------------------------------------------------------------



                        VOTING RIGHTS AND REQUIRED VOTE

Each share of your fund is entitled to one vote.  Approval of the above proposal
requires  the  affirmative  vote  of a  majority  of the  shares  of  your  fund
outstanding  and  entitled  to  vote.  For  this  purpose,  a  majority  of  the
outstanding shares of your fund means the vote of the lesser of

(1) 67% or more of the shares  present at the  meeting,  if the  holders of more
than 50% of the shares of the fund are present or represented by proxy, or

(2) more than 50% of the outstanding shares of the fund.

Shares of your fund  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 there is a quorum 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  present and entitled to vote on
the  proposal.  Thus,  a  "broker  non-vote"  has no  effect  on the  voting  in
determining  whether the proposal has been adopted in accordance with clause (1)

                                       27

<PAGE>

above,  if more  than  50% of the  outstanding  shares  (excluding  the  "broker
non-votes")  are present or  represented.  However,  for purposes of determining
whether the  proposal has been adopted in  accordance  with clause (2) above,  a
"broker  non-vote"  has the same effect as a vote against the  proposal  because
shares  represented  by a "broker  non-vote" are  considered  to be  outstanding
shares.

If the  required  approval  of  shareholders  is not  obtained,  your  fund will
continue  to engage  in  business  as a  separate  mutual  fund and the board of
trustees will consider what further action may be appropriate.

                       INFORMATION CONCERNING THE MEETING

Solicitation of Proxies

In addition to the mailing of these proxy materials, proxies may be solicited by
telephone,  by fax or in person by the trustees,  officers and employees of your
fund; by personnel of your fund's  investment  adviser,  John Hancock  Advisers,
Inc. and its  transfer  agent,  John Hancock  Signature  Services,  Inc.;  or by
broker-dealer   firms.   Signature   Services,   together  with  a  third  party
solicitation  firm,  has agreed to provide proxy  solicitation  services to your
fund at a cost of approximately $3,000.

Revoking Proxies

A Limited-Term Government Fund shareholder signing and returning a proxy has the
power to revoke it at any time before it is exercised:

o        By filing a written  notice of  revocation  with your  fund's  transfer
         agent, John Hancock Signature Services, Inc., 1 John Hancock Way, Suite
         1000, Boston, Massachusetts 02217-1000, or

o        By returning a duly executed proxy with a later date before the time
         of the meeting, or

o        If a shareholder has executed a proxy but is present at the meeting and
         wishes to vote in  person,  by  notifying  the  secretary  of your fund
         (without  complying  with any  formalities)  at any time  before  it is
         voted.

Being  present at the meeting  alone does not revoke a  previously  executed and
returned proxy.


                                       28
<PAGE>

Outstanding Shares and Quorum

   
As of September 17, 1997, 18,146,959 Class A shares and 1,242,698 Class B shares
of  beneficial  interest of your fund were  outstanding.  Only  shareholders  of
record on September  17, 1997 (the "record  date") are entitled to notice of and
to vote at the meeting.  A majority of the outstanding  shares of your fund that
are  entitled  to vote  will be  considered  a  quorum  for the  transaction  of
business.
    

Other Business

Your  fund's  board  of  trustees  knows  of no  business  to be  presented  for
consideration  at the  meeting  other than the  proposal.  If other  business is
properly brought before the meeting, proxies will be voted according to the best
judgment of the persons named as proxies.

Adjournments

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  concerning the proposal.  Any adjournment will
require the affirmative  vote of a majority of your fund's shares at the session
of the Meeting to be  adjourned.  If an  adjournment  of the meeting is proposed
because there are not  sufficient  votes in favor of the  proposal,  the persons
named as proxies  will vote those  proxies  favoring  the  proposal  in favor of
adjournment,  and will vote those  proxies  against the  reorganization  against
adjournment.

Telephone Voting

In addition to soliciting  proxies by mail,  by fax or in person,  your fund may
also arrange to have votes  recorded by  telephone by officers and  employees of
your fund or by personnel of the adviser or transfer agent. The telephone voting
procedure is designed to verify 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,
these  telephone  votes would not be counted at the  meeting.  Your fund has not
obtained an opinion of counsel  about  telephone  voting,  but is currently  not
aware of any challenge.

                                       29

<PAGE>

o        A shareholder will be called on a recorded line at the telephone number
         in the  fund's  account  records  and  will be  asked  to  provide  the
         shareholder's social security number or other identifying information.

o        The shareholder will then be given an opportunity to authorize  proxies
         to vote  his or her  shares  at the  meeting  in  accordance  with  the
         shareholder's instructions.

o        To  ensure  that the  shareholder's  instructions  have  been  recorded
         correctly,  the  shareholder  will also receive a  confirmation  of the
         voting instructions by mail.

o        A toll-free number will be available in case the voting information
         contained in the confirmation is incorrect.

o        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.

                                    EXHIBIT A

                      AGREEMENT AND PLAN OF REORGANIZATION

THIS AGREEMENT AND PLAN OF REORGANIZATION (the "Agreement") is made this 1st day
of October,  1997, by and between John Hancock Intermediate  Maturity Government
Fund  (the  "Acquiring   Fund"),   a  series  of  John  Hancock  Bond  Trust,  a
Massachusetts  business  trust (the  "Trust"),  and John  Hancock  Limited  Term
Government Fund (the "Acquired Fund"), a Massachusetts business trust, each with
their   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

                                      A-1

<PAGE>

     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  to its  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  December  5,  1997 (the
     "Closing  Date"),  of a number  of the  Acquiring  Fund  Shares  having  an
     aggregate  net asset value  equal,  in the case of each class of  Acquiring
     Fund  Shares,  to the value of the assets,  less such  liabilities  (herein
     referred  to as  the  "net  value  of  the  assets")  attributable  to  the
     applicable  class,  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.

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  (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

                                      A-2

<PAGE>

     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 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
     Signature Services, Inc. prior to the Closing Date. Any Acquired Fund share
     certificate  which remains  outstanding on the Closing Date shall be deemed
     to be canceled,  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.

1.6  Any transfer taxes payable upon issuance of Acquiring Fund Shares in a name
     other than the  registered  holder of the Acquired Fund Shares on the books
     of the Acquired Fund as of that time shall, as a condition of such issuance
     and transfer,  be paid by the person to whom such Acquiring Fund Shares are
     to be issued and transferred.

1.7  The  existence  of the  Acquired  Fund shall be  terminated  as promptly as
     practicable following the Liquidation Date.

1.8  Any  reporting  responsibility  of the Acquired  Fund,  including,  but not
     limited  to, the  responsibility  for  filing of  regulatory  reports,  tax
     returns,  or other  documents with the  Securities and Exchange  Commission
     (the  "Commission"),  any state  securities  commissions,  and any federal,
     state or local tax authorities or any other relevant regulatory  authority,
     is and shall remain the responsibility of the Acquired Fund.

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  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 Acquiring Fund's  Declaration of Trust as amended and restated
     (the "Declaration"),  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 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 December 5, 1997 or such other date on or before
     June 30,  1998 as the parties  may agree.  The Closing  shall be held as of
     5:00 p.m. at the offices of the Trust and the Acquired Fund, 101 Huntington
     Avenue, Boston,  Massachusetts 02199, or at such other time and/or place as
     the parties may agree.

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

                                      A-4

<PAGE>

     the Acquired  Fund to the  Custodian  for  examination  no later than three
     business days preceding the Closing Date.  Portfolio  securities  which are
     not held in book-entry  form shall be delivered by the Acquired Fund to the
     Custodian for the 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  book-entry  form on  behalf  of the
     Acquired Fund shall be delivered to the Acquiring  Fund by the Custodian by
     recording the transfer of beneficial  ownership 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  June 30,  1998,  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,
     addresses,  federal taxpayer  identification numbers and backup withholding
     and nonresident alien withholding  status of the Acquired Fund shareholders
     and the number of outstanding  shares of each class of beneficial  interest
     of the Acquired Fund owned by each such shareholder, all as of the close of
     business on the Closing  Date,  certified  by its  Treasurer,  Secretary or
     other authorized officer (the "Shareholder List"). The Acquiring Fund shall
     issue and  deliver  to the  Acquired  Fund a  confirmation  evidencing  the
     Acquiring  Fund  Shares to be  credited  on the  Closing  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 the
     Acquiring Fund. At the Closing,  each party shall deliver to the other such
     bills of sale, checks, assignments,  stock certificates,  receipts or other
     documents as such other party or its counsel may reasonably request.

          accepted accounting principles consistently applied, and there were no
          known actual or contingent  liabilities of the Acquired Fund as of the
          respective dates thereof not disclosed therein;

     (g)  Since May 31, 1997,  there has not been any material adverse change in
          the Acquired  Fund's  financial  condition,  assets,  liabilities,  or
          business  other  than  changes  occurring  in the  ordinary  course of
          business,  or any  incurrence  by the  Acquired  Fund of  indebtedness
          maturing  more  than one year  from the  date  such  indebtedness  was

          transfer thereof, including such restrictions as might arise under the
          Securities Act of 1933, as amended (the "1933 Act");

          duly  authorized by all  necessary  action on the part of the Acquired
          Fund, and this Agreement constitutes a valid and binding obligation of
          the Acquired Fund enforceable in accordance with its terms, subject to
          the approval of the Acquired Fund's shareholders;

          Statement,   on  the  date  of  the  meeting  of  the  Acquired   Fund
          shareholders  and on the  Closing  Date,  shall not contain any untrue

          and local  authorizations  to own all of its properties and assets and
          to carry on its business as now being conducted;

     (b)  The  Trust  is  a  registered   investment  company  classified  as  a
          management  company and its  registration  with the  Commission  as an
          investment company under the 1940 Act is in full force and effect. The
          Acquiring Fund is a diversified series of the Trust;

     (c)  The prospectus  (the  "Acquiring  Fund  Prospectus")  and statement of

          and the  Registration  Statement on Form N-14 filed in connection with
          this  Agreement  (the  "Registration  Statement")  (other than written
          information  furnished by the Acquired Fund for inclusion therein,  as
          covered by the Acquired  Fund's  warranty in Paragraph  4.1(m) hereof)
          will conform in all material  respects to the applicable  requirements
          of the 1933 Act and the 1940 Act and the rules and  regulations of the

          Commission thereunder,  the Acquiring Fund Prospectus does not include
          any untrue  statement of a material fact or omit to state any material
          fact required to be stated therein or necessary to make the statements
          therein, in light of the circumstances under which they were made, not
          misleading and the Registration  Statement will not include any untrue
          statement of material fact or omit to state any material fact required
          to be stated therein or necessary to make the statements  therein,  in
          light of the circumstances under which they were made, not misleading;

     (d)  At the Closing Date,  the Trust on behalf of the  Acquiring  Fund will
          have good and marketable title to the assets of the Acquiring Fund;

     (e)  The Trust and the Acquiring Fund are not, and the execution,  delivery
          and  performance  of their  obligations  under this Agreement will not
          result in a violation of any provisions of the Trust's Declaration, or
          By-Laws or of any agreement, indenture, instrument, contract, lease or
          other  undertaking to which the Trust or the Acquiring Fund is a party
          or by which the Trust or the Acquiring Fund is bound;

     (f)  Except as otherwise  disclosed in writing and accepted by the Acquired
          Fund,  no  material   litigation  or   administrative   proceeding  or
          investigation of or before any court or governmental body is currently
          pending or threatened  against the Trust or the Acquiring  Fund or any
          of the Acquiring  Fund's  properties or assets.  The Trust knows of no
          facts  which  might  form  the  basis  for  the  institution  of  such
          proceedings,  and neither the Trust nor the Acquiring  Fund is a party
          to or subject to the  provisions  of any order,  decree or judgment of
          any court or governmental  body which materially and adversely affects
          the  Acquiring  Fund's  business  or its  ability  to  consummate  the
          transactions herein contemplated;

     (g)  The  statement of assets and  liabilities,  including  the schedule of

          period  from  April 1,  1997 to May 31,  1997,  and the  statement  of
          changes in net assets for the years  ended March 31, 1996 and 1997 and
          the period  from  April 1, 1997 to May 31,  1997  (audited  by Ernst &
          Young LLP) (copies of which have been furnished to the Acquired Fund),
          present fairly in all material respects the financial condition of the
          Acquiring  Fund as of May 31, 1997 and the  results of its  operations
          for the  period  then  ended in  accordance  with  generally  accepted
          accounting  principles  consistently  applied, and there were no known

                                      A-10

<PAGE>

          actual  or  contingent  liabilities  of the  Acquiring  Fund as of the
          respective dates thereof not disclosed therein;

     (h)  Since May 31, 1997,  there has not been any material adverse change in
          the Acquiring  Fund's  financial  condition,  assets,  liabilities  or
          business  other  than  changes  occurring  in the  ordinary  course of
          business,  or any  incurrence  by the Trust on behalf of the Acquiring
          Fund of  indebtedness  maturing  more than one year from the date such
          indebtedness was incurred,  except as disclosed to and accepted by the
          Acquired Fund;

     (i)  Each of the  Acquiring  Fund and its  predecessors  has qualified as a
          regulated  investment  company for each taxable year of its  operation
          and the Acquiring Fund will qualify as such as of the Closing Date;

     (j)  The authorized capital of the Trust consists of an unlimited number of
          shares of beneficial interest,  no par value per share. All issued and
          outstanding  shares of beneficial  interest of the Acquiring Fund are,
          and at  the  Closing  Date  will  be,  duly  and  validly  issued  and
          outstanding,  fully paid and nonassessable by the Trust. The Acquiring
          Fund does not have  outstanding any options,  warrants or other rights
          to subscribe for or purchase any of its shares of beneficial interest,
          nor is there  outstanding  any  security  convertible  into any of its
          shares of beneficial interest;

     (k)  The  execution,  delivery and  performance  of this Agreement has been
          duly  authorized by all  necessary  action on the part of the Trust on
          behalf of the Acquiring  Fund, and this Agreement  constitutes a valid
          and binding obligation of the Acquiring Fund enforceable in accordance
          with its terms;

     (l)  The  Acquiring  Fund Shares to be issued and delivered to the Acquired
          Fund  pursuant  to the terms of this  Agreement,  when so  issued  and
          delivered,  will be duly  and  validly  issued  shares  of  beneficial
          interest   of  the   Acquiring   Fund  and  will  be  fully  paid  and
          nonassessable by the Trust;

     (m)  The  information  to be  furnished  by the  Acquiring  Fund for use in
          applications for orders, registration statements,  proxy materials and
          other  documents  which  may  be  necessary  in  connection  with  the
          transactions  contemplated  hereby  shall be accurate and complete and
          shall comply in all material  respects  with  federal  securities  and
          other laws and regulations applicable thereto; and

                                      A-11

<PAGE>

     (n)  No  consent,  approval,   authorization  or  order  of  any  court  or
          governmental  authority  is  required  for  the  consummation  by  the
          Acquiring  Fund of the  transactions  contemplated  by the  Agreement,
          except for the  registration  of the  Acquiring  Fund Shares under the
          1933 Act and the 1940 Act.

          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) 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

          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

     (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 beneficial interest of the
          Acquired  Fund  solely  for  Acquiring  Fund  Shares  as  part  of the
          transaction;

     (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

and provide  representations  which are reasonably  necessary to enable Hale and

Overview

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

GOAL OF THE INCOME FUNDS

John Hancock income funds seek current income without sacrificing total return.
Some of the funds also invest for stability of principal. Each fund has its own
strategy and its own risk/reward profile. Because you could lose money by
investing in these funds, be sure to read all risk disclosure carefully before
investing.

WHO MAY WANT TO INVEST

These funds may be appropriate for investors who:

o  are seeking a regular stream of income

o  are seeking higher potential returns than money market funds and are willing
   to accept moderate risk of volatility

o  want to diversify their portfolios

o  are seeking a mutual fund for the income portion of an asset allocation
   portfolio

o  are retired or nearing retirement

Income funds may NOT be appropriate if you:

o  are investing for maximum return over a long time horizon

o  require absolute stability of your principal

THE MANAGEMENT FIRM

   
All John Hancock income funds are managed by John Hancock Advisers, Inc. Founded
in 1968, John Hancock Advisers is a wholly owned subsidiary of John Hancock
Mutual Life Insurance Company and manages more than $22 billion in assets.

Government Income Fund

REGISTRANT NAME: JOHN HANCOCK BOND TRUST 
                              TICKER SYMBOL     CLASS A: JHGIX    CLASS B: TSGIX
- --------------------------------------------------------------------------------

GOAL AND STRATEGY
[Clip art] The fund seeks to earn a high level of current income consistent with
preservation of capital. To pursue this goal, the fund invests primarily in U.S.
Government and agency securities of any maturity, as described below. Stability
of share price is a secondary goal.

PORTFOLIO SECURITIES
[Clip art] Under normal circumstances, the fund invests at least 80% of assets
in securities that are issued, or guaranteed as to principal and interest, by
the U.S. Government, its agencies or instrumentalities. These may include
Treasuries, mortgage-backed securities such as Ginnie Maes, Freddie Macs and
Fannie Maes, and repurchase agreements and forward commitments involving these
securities.

   
For liquidity and flexibility, the fund may place up to 20% of assets in
high-quality short-term securities. In abnormal market conditions, it may invest
more assets in these securities as a defensive tactic. The fund also may invest
in certain higher-risk investments, including asset-backed securities, U.S.
dollar-denominated foreign government securities and derivative and leveraged
investments, and may engage in other investment practices. Investments in
asset-backed and foreign government securities must be in the two highest and
four highest rating categories, respectively, or if unrated, be of comparable
quality. Up to 10% of assets may be invested in foreign government bonds rated
BB/Ba or B (junk bonds).
    

RISK FACTORS
[Clip art] As with most income funds, the value of your investment will
fluctuate with changes in interest rates. Typically, a rise in interest rates
causes a decline in the market value of debt securities (including U.S.
Government and mortgage-backed securities). To the extent that the fund invests
in mortgage-backed securities, it may also be subject to extension and
prepayment risks. These risks are defined in "More about risk" starting on page
29. Other factors may affect the market price and yield of the fund's
securities, including investor demand and domestic and worldwide economic
conditions.

The U.S. Government does not guarantee the market value or the current yield of
government securities, nor does the government's guarantee in any way extend to
the fund itself. Please read "More about risk" carefully before investing.

PORTFOLIO MANAGEMENT
[Clip art] Barry H. Evans, CFA, leader of the fund's portfolio management team
since January 1995, is a senior vice president of the adviser. He has been in
the investment business since joining John Hancock Funds in 1986.

- --------------------------------------------------------------------------------
INVESTOR EXPENSES
[Clip art] Fund investors pay various expenses, either directly or indirectly.
The figures below show the expenses for the past year, adjusted to reflect any
changes. Future expenses may be greater or less.

Other expenses                                  0.25%       0.25%
Total fund operating expenses                   1.13%       1.88%
    

Example The table below shows what you would pay if you invested $1,000 over the
various time frames indicated. The example assumes you reinvested all dividends
and that the average annual return was 5%.

   
- --------------------------------------------------------------------------------
Share class                         Year 1   Year 3   Year 5   Year 10
- --------------------------------------------------------------------------------
Class A shares                      $56      $79      $104     $176
Class B shares
  Assuming redemption
  at end of period                  $69      $89      $122     $200
  Assuming no redemption            $19      $59      $102     $200
    

This example is for comparison purposes only and is not a representation of the
fund's actual expenses and returns, either past or future.

(1)   Except for investments of $1 million or more; see "How sales charges are
      calculated."
(2)   Does not include wire redemption fee (currently $4.00).
(3)   Because of the 12b-1 fee, long-term shareholders may indirectly pay more
      than the equivalent of the maximum permitted front-end sales charge.

High Yield Bond Fund

REGISTRANT NAME: JOHN HANCOCK BOND TRUST
                               TICKER SYMBOL      CLASS A: JHHBX  CLASS B: TSHYX
- --------------------------------------------------------------------------------

GOAL AND STRATEGY
[Clip art] The fund seeks to maximize current income without assuming undue
risk. To pursue this goal, the fund invests primarily in junk bonds, i.e.
lower-rated, higher-yielding debt securities.

Because the performance of junk bonds has historically been influenced by
economic conditions, the fund may rotate securities selection by business sector
according to the economic outlook.

The fund also seeks capital appreciation, but only when consistent with its
primary goal.

   
PORTFOLIO SECURITIES
[Clip art] Under normal circumstances, the fund invests at least 65% of assets
in bonds rated lower than BBB/Baa and their unrated equivalents. Up to 30% of
assets may be invested in bonds rated CC/Ca. Up to 40% of assets may be invested
in the securities of issuers in the electric utility and telephone industries.
For all other industries, the limitation is 25% of assets.
    

Types of bonds include, but are not limited to, domestic and foreign corporate
bonds, debentures, notes, convertible securities, preferred stocks, municipal
obligations and government obligations.

The fund may also invest up to 20% of net assets in U.S. or foreign equities.

For liquidity and flexibility, the fund may place up to 35% of assets in
investment-grade short-term securities. In abnormal market conditions, it may
invest more assets in these securities as a defensive tactic. The fund also may
invest in certain higher-risk investments, including restricted securities, and
may engage in other investment practices.

   
RISK FACTORS
[Clip art] Investors should expect greater fluctuations in share price, yield
and total return compared with less aggressive bond funds. These fluctuations,
whether positive or negative, may be sharp and unanticipated.

Issuers of junk bonds are typically in weak financial health and their ability
to pay interest and principal is uncertain. Compared with issuers of
investment-grade bonds, they are more likely to encounter financial difficulties
and to be materially affected by these difficulties when they do encounter them.
Junk bond markets may react strongly to adverse news about an issuer or the
economy, or to the perception or expectation of adverse news. Before you invest,
please read "More about risk" starting on page 29.

PORTFOLIO MANAGEMENT
[Clip art] Arthur N. Calavritinos, CFA, leader of the fund's portfolio
management team since July 1995, is a vice president of the adviser. He joined
John Hancock Funds in 1988 and has been in the investment business since 1987.

Example The table below shows what you would pay if you invested $1,000 over the
various time frames indicated. The example assumes you reinvested all dividends
and that the average annual return was 5%.

Class B shares
  Assuming redemption
  at end of period                  $68      $86      $117     $191
  Assuming no redemption            $18      $56      $97      $191
    

This example is for comparison purposes only and is not a representation of the
fund's actual expenses and returns, either past or future.

(1)   Except for investments of $1 million or more; see "How sales charges are
      calculated."
(2)   Does not include wire redemption fee (currently $4.00).
(3)   Because of the 12b-1 fee, long-term shareholders may indirectly pay more
      than the equivalent of the maximum permitted front-end sales charge.

Intermediate Maturity Government Fund

REGISTRANT NAME: JOHN HANCOCK BOND TRUST
                               TICKER SYMBOL      CLASS A: TAUSX  CLASS B: TSUSX
- --------------------------------------------------------------------------------

GOAL AND STRATEGY
[Clip art] The fund seeks to earn a high level of current income consistent with
preservation of capital and maintenance of liquidity. To pursue this goal, the
fund invests primarily in U.S. Government securities of any maturity, as
described below. The fund's weighted average maturity will typically be between
three and ten years.

   
PORTFOLIO SECURITIES
[Clip art] Under normal circumstances, the fund invests at least 80% of assets
in securities that are issued, or guaranteed as to principal and interest, by
the U.S. Government, its agencies or instrumentalities. These may include
Treasuries and mortgage-backed securities such as Ginnie Maes and Fannie Maes.
The fund may invest up to 20% in asset-backed securities or corporate debt
securities rated AAA/Aaa and their unrated equivalents.

For liquidity and flexibility, the fund may place up to 20% of assets in
high-quality short-term securities. In abnormal market conditions, it may invest
more assets in these securities as a defensive tactic. The fund also may invest
in certain higher-risk investments, including derivative and leveraged
investments, and may engage in other investment practices.
    

RISK FACTORS
[Clip art] As with most income funds, the value of your investment will
fluctuate with changes in interest rates. Typically, a rise in interest rates
causes a decline in the market value of debt securities (including U.S.
Government and mortgage-backed securities). To the extent that the fund invests
in mortgage-backed securities, it may also be subject to extension and
prepayment risks. These risks are defined in "More about risk" starting on page
29. Other factors may affect the market price and yield of the fund's
securities, including investor demand and domestic and worldwide economic
conditions.

The U.S. Government does not guarantee the market value or the current yield of
government securities, nor does the government's guarantee in any way extend to
the fund itself. Please read "More about risk" carefully before investing.

PORTFOLIO MANAGEMENT
[Clip art] Roger C. Hamilton, leader of the fund's portfolio management team
since January 1992 (with the fund's previous adviser), is a vice president of
the adviser. He joined John Hancock Funds in December 1994 and has been in the
investment business since 1980.

- --------------------------------------------------------------------------------
INVESTOR EXPENSES
[Clip art] Fund investors pay various expenses, either directly or indirectly.
The figures below show the expenses for the past year, adjusted to reflect any
changes. Future expenses may be greater or less.

Other expenses (after limitation)(3)                  0.50%       0.50%
Total fund operating expenses (after limitation)(3)   0.75%       1.50%

Example The table below shows what you would pay if you invested $1,000 over the
various time frames indicated. The example assumes you reinvested all dividends
and that the average annual return was 5%.

- --------------------------------------------------------------------------------
Share class                         Year 1   Year 3   Year 5   Year 10
- --------------------------------------------------------------------------------
Class A shares                      $37      $53      $70      $120
Class B shares
  Assuming redemption
  at end of period                  $45      $67      $82      $131
  Assuming no redemption            $15      $47      $82      $131

This example is for comparison purposes only and is not a representation of the
fund's actual expenses and returns, either past or future.

   
(1)   Except for investments of $1 million or more; see "How sales charges are
      calculated."
(2)   Does not include wire redemption fee (currently $4.00).
(3)   Reflects the adviser's temporary agreement to limit expenses (except for
      12b-1 and other class-specific expenses). Without this limitation,
      management fees would be 0.40% for each class, other expenses would be
      1.27% for each class and total fund operating expenses would be 1.92% for
      Class A and 2.67% for Class B.

Limited-Term Government Fund

REGISTRANT NAME: JOHN HANCOCK LIMITED-TERM GOVERNMENT FUND
                                    TICKER SYMBOL CLASS A: JHNLX  CLASS B: JHLBX
- --------------------------------------------------------------------------------

GOAL AND STRATEGY
[Clip art] The fund seeks to provide current income and security of principal.
To pursue this goal, the fund invests primarily in U.S. Government and agency
securities, as described below. The fund's securities may be of any maturity,
although a substantial portion typically will have maturities of ten years or
less.

PORTFOLIO SECURITIES
[Clip art] Under normal circumstances, the fund invests at least 80% of assets
in securities that are issued, or guaranteed as to principal and interest, by
the U.S. Government, its agencies or instrumentalities. These may include
Treasuries and mortgage-backed securities such as Ginnie Maes and Fannie Maes.

For liquidity and flexibility, the fund may place up to 20% of assets in
investment-grade short-term securities. In abnormal market conditions, it may
invest more assets in these securities as a defensive tactic. The fund also may
invest in certain higher-risk investments, and may engage in other investment
practices.

RISK FACTORS
[Clip art] In seeking to maintain a relatively stable share price, the fund may
sacrifice opportunities for higher yields. At the same time, its share price
will fluctuate to some extent with changes in interest rates. Typically, a rise
in interest rates causes a decline in the market value of debt securities
(including U.S. Government and mortgage-backed securities). To the extent that
the fund invests in mortgage-backed securities, it may also be subject to
extension and prepayment risks. These risks are defined in "More about risk"
starting on page 29.

Other factors may affect the market price and yield of the fund's securities,
including investor demand and domestic and worldwide economic conditions. The
U.S. Government does not guarantee the market value or the current yield of
government securities, nor does the government's guarantee in any way extend to
the fund itself. Please read "More about risk" carefully before investing.

PORTFOLIO MANAGEMENT
[Clip art] Barry H. Evans, CFA, leader of the fund's portfolio management team
since January 1995, is a senior vice president of the adviser. He has been in
the investment business since joining John Hancock Funds in 1986.

- --------------------------------------------------------------------------------
INVESTOR EXPENSES
[Clip art] Fund investors pay various expenses, either directly or indirectly.
The figures below show the expenses for the past year, adjusted to reflect any

Other expenses                                  0.44%       0.44%
Total fund operating expenses                   1.34%       2.04%
    

Example The table below shows what you would pay if you invested $1,000 over the
various time frames indicated. The example assumes you reinvested all dividends
and that the average annual return was 5%.

   
- --------------------------------------------------------------------------------
Share class                         Year 1   Year 3   Year 5   Year 10
- --------------------------------------------------------------------------------
Class A shares                      $43      $71      $101     $186
Class B shares
  Assuming redemption
  at end of period                  $51      $84      $110     $195
  Assuming no redemption            $21      $64      $110     $195
    

This example is for comparison purposes only and is not a representation of the
fund's actual expenses and returns, either past or future.

(1)   Except for investments of $1 million or more; see "How sales charges are
      calculated."
(2)   Does not include wire redemption fee (currently $4.00).
(3)   Because of the 12b-1 fee, long-term shareholders may indirectly pay more
      than the equivalent of the maximum permitted front-end sales charge.

Sovereign Bond Fund

REGISTRANT NAME: JOHN HANCOCK SOVEREIGN BOND FUND
                               TICKER SYMBOL      CLASS A: JHNBX  CLASS B: JHBBX
- --------------------------------------------------------------------------------

GOAL AND STRATEGY
[Clip art] The fund seeks to generate a high level of current income consistent
with prudent investment risk. To pursue this goal, the fund invests in a
diversified portfolio of marketable debt securities. These securities are
primarily investment grade, although up to 25% of them may be junk bonds rated
as low as CC/Ca and their unrated equivalents. The fund does not concentrate its
investments in any particular industry.

PORTFOLIO SECURITIES
[Clip art] Under normal circumstances, the fund invests at least 65% of assets
in corporate and government bonds and debentures. Typically, at least
three-quarters of these debt securities (excluding commercial paper) will be: 
o  securities of any type of issuer that are rated among the four highest
   Moody's or S&P rating categories and their unrated equivalents
o  U.S. Government and agency securities

The fund may invest up to 25% of assets in U.S. dollar-denominated foreign
securities.

For liquidity and flexibility, the fund may place up to 35% of assets in
investment-grade short-term securities. In abnormal market conditions, it may
invest more assets in these securities as a defensive tactic. The fund also may
invest in certain higher-risk investments, including asset-backed securities and
derivatives and leveraged investments, and may engage in other investment
practices.

RISK FACTORS
[Clip art] Investors should expect fluctuations in share price, yield and total
return, particularly with changes in interest rates. Typically, a rise in
interest rates causes a decline in the market value of debt securities. To the
extent that it invests in certain securities, the fund may be affected by
additional risks: 
o  junk bonds: above-average credit, market and other risks
o  foreign securities: currency, information, natural event and political risks
o  mortgage-backed securities: extension and prepayment risks

These risks are defined in "More about risk" starting on page 29. The longer the
fund's average weighted maturity, the more it is likely to be affected by a
change in interest rates. Please read "More about risk" carefully before
investing.

PORTFOLIO MANAGEMENT
[Clip art] James K. Ho, CFA, leader of the fund's portfolio management team
since March 1988, is an executive vice president of the adviser. He joined John
Hancock Funds in 1985 and has been in the investment business since 1977.

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

Other expenses                                  0.31%       0.31%
Total fund operating expenses                   1.11%       1.81%
    

Example The table below shows what you would pay if you invested $1,000 over the
various time frames indicated. The example assumes you reinvested all dividends
and that the average annual return was 5%.

   
- --------------------------------------------------------------------------------
Share class                         Year 1   Year 3   Year 5   Year 10
- --------------------------------------------------------------------------------
Class A shares                      $56      $78      $103     $173
Class B shares
  Assuming redemption
  at end of period                  $69      $87      $118     $194
  Assuming no redemption            $19      $57      $98      $194
    

This example is for comparison purposes only and is not a representation of the
fund's actual expenses and returns, either past or future.

(1)   Except for investments of $1 million or more; see "How sales charges are
      calculated."
(2)   Does not include wire redemption fee (currently $4.00).
(3)   Because of the 12b-1 fee, long-term shareholders may indirectly pay more
      than the equivalent of the maximum permitted front-end sales charge.

Sovereign U.S. Government Income Fund

REGISTRANT NAME: JOHN HANCOCK STRATEGIC SERIES
                               TICKER SYMBOL      CLASS A: JHSGX  CLASS B: FGOPX
- --------------------------------------------------------------------------------

GOAL AND STRATEGY
[Clip art] The fund seeks to provide as high a level of income as is consistent
with long-term total return. To pursue this goal, the fund invests in U.S.
Government and agency securities, as described below.

PORTFOLIO SECURITIES
[Clip art] Under normal circumstances, the fund invests at least 65% of assets
in securities that are issued, or guaranteed as to principal and interest, by
the U.S. Government, its agencies or instrumentalities. These may include
Treasuries and mortgage-backed securities such as Ginnie Maes and Fannie Maes.

For liquidity and flexibility, the fund may place up to 35% of assets in
investment-grade short-term securities. In abnormal market conditions, it may
invest more assets in these securities as a defensive tactic. The fund also may
invest in certain higher-risk investments, including derivative and leveraged
investments, and may engage in other investment practices.

RISK FACTORS
[Clip art] As with most income investments, the value of your investment will
fluctuate with changes in interest rates. Typically, a rise in interest rates
causes a decline in the market value of debt securities (including U.S.
Government and mortgage-backed securities). To the extent that the fund invests
in mortgage-backed securities, it may also be subject to extension and
prepayment risks. These risks are defined in "More about risk" starting on page
29. Other factors may affect the market price and yield of the fund's
securities, including investor demand and economic conditions.

The U.S. Government does not guarantee the market value or the current yield of
government securities, nor does the government's guarantee in any way extend to
the fund itself. Please read "More about risk" carefully before investing.

PORTFOLIO MANAGEMENT
[Clip art] Barry H. Evans, CFA, leader of the fund's portfolio management team
since January 1995, is a senior vice president of the adviser. He has been in
the investment business since joining John Hancock Funds in 1986.

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

(1)   Except for investments of $1 million or more; see "How sales charges are
      calculated."
(2)   Does not include wire redemption fee (currently $4.00).
(3)   Because of the 12b-1 fee, long-term shareholders may indirectly pay more
      than the equivalent of the maximum permitted front-end sales charge.

Strategic Income Fund

REGISTRANT NAME: JOHN HANCOCK STRATEGIC SERIES
                               TICKER SYMBOL      CLASS A: JHFIX  CLASS B: STIBX
- --------------------------------------------------------------------------------

GOAL AND STRATEGY
[Clip art] The fund seeks a high level of current income. To pursue this goal,
the fund invests primarily in three sectors:
o  foreign government and corporate debt securities
o  U.S. Government and agency securities
o  junk bonds rated as low as CC/Ca and their unrated equivalents.

Under normal circumstances, the fund's assets will be invested in all three
sectors. However, the weighting of assets among sectors will be adjusted to
reflect current or anticipated market behavior, and the fund may invest up to
100% of assets in any sector.

PORTFOLIO SECURITIES
[Clip art] The fund may invest in debt securities of all maturities and types,
including bonds, debentures, notes, preferred stock, mortgage-backed and
asset-backed securities and others. The fund may also invest up to 10% of net
assets in U.S. or foreign equities.

For liquidity and flexibility, the fund may invest in investment-grade
short-term securities. In abnormal market conditions, it may invest more assets
in these securities as a defensive tactic. The fund also may invest in certain
higher-risk investments, including derivative and leveraged investments, and may
engage in other investment practices.

RISK FACTORS
[Clip art] Investors should expect fluctuations in share price, yield and total
return that are above-average for bond funds. Typically, a rise in interest
rates causes a decline in the market value of debt securities. The longer the
fund's average weighted maturity, the more it is likely to be affected by a
change in interest rates. To the extent that the fund invests in mortgage-backed
securities, it may also be subject to extension and prepayment risks. These
risks are defined in "More about risk" starting on page 29. Foreign securities
carry additional risks, including currency, information, natural event and
political risks. Issuers of junk bonds are typically in weak financial health,
and their ability to pay interest and principal is uncertain, especially in an
adverse economy. Junk bond markets may react strongly to adverse news about an
issuer or the economy, or to the perception or expectation of adverse news.
Please read "More about risk" carefully before investing.

PORTFOLIO MANAGEMENT
[Clip art] Frederick L. Cavanaugh, Jr., leader of the fund's portfolio
management team since 1986, is a senior vice president of the adviser. He joined
John Hancock Funds in 1986 and has been in the investment business since 1973.

Example The table below shows what you would pay if you invested $1,000 over the
various time frames indicated. The example assumes you reinvested all dividends
and that the average annual return was 5%.

   
- --------------------------------------------------------------------------------
Share class                         Year 1   Year 3   Year 5   Year 10
- --------------------------------------------------------------------------------
Class A shares                      $55      $75      $98      $162
Class B shares
  Assuming redemption
  at end of period                  $67      $84      $112     $182
  Assuming no redemption            $17      $54      $92      $182
    

This example is for comparison purposes only and is not a representation of the
fund's actual expenses and returns, either past or future.

(1)   Except for investments of $1 million or more; see "How sales charges are
      calculated."
(2)   Does not include wire redemption fee (currently $4.00).
(3)   Because of the 12b-1 fee, long-term shareholders may indirectly pay more
      than the equivalent of the maximum permitted front-end sales charge.

Investments of $1 million or more Class A shares are available with no front-end
sales charge. However, there is a contingent deferred sales charge (CDSC) on any
shares sold within one year of purchase, as follows:

- --------------------------------------------------------------------------------
CDSC on $1 million+ investments (Groups 1 and 2)
- --------------------------------------------------------------------------------
Your investment                     CDSC on shares being sold

First $1M - $4,999,999              1.00%
Next $1 - $5M above that            0.50%
Next $1 or more above that          0.25%

For purposes of this CDSC, all purchases made during a calendar month are
counted as having been made on the LAST day of that month.

The CDSC is based on the lesser of the original purchase cost or the current
market value of the shares being sold, and is not charged on shares you acquired
by reinvesting your dividends. To keep your CDSC as low as possible, each time
you place a request to sell shares we will first sell any shares in your account
that are not subject to a CDSC.

Class B Shares are offered at their net asset value per share, without any
initial sales charge. However, you may be charged a contingent deferred sales
charge (CDSC) on shares you sell within a certain time after you bought them, as
described in the table below. There is no CDSC on shares acquired through
reinvestment of dividends. The CDSC is based on the original purchase cost or
the current market value of the shares being sold, whichever is less. The longer
the time between the purchase and the sale of shares, the lower the rate of the
CDSC:

For purposes of this CDSC, all purchases made during a calendar month are
counted as having been made on the FIRST day of that month.

CDSC calculations are based on the number of shares involved, not on the value
of your account. To keep your CDSC as low as possible, each time you place a
request to sell shares we will first sell any shares in your account that carry
no CDSC. If there are not enough of these to meet your request, we will sell
those shares that have the lowest CDSC.

SALES CHARGE REDUCTIONS AND WAIVERS

Reducing your Class A sales charges There are several ways you can combine
multiple purchases of Class A shares of John Hancock funds to take advantage of
the breakpoints in the sales charge schedule. The first three ways can be
combined in any manner.

o     Accumulation Privilege -- lets you add the value of any Class A shares you
      already own to the amount of your next Class A investment for purposes of
      calculating the sales charge.
o     Letter of Intention -- lets you purchase Class A shares of a fund over a
      13-month period and receive the same sales charge as if all shares had
      been purchased at once.
o     Combination Privilege -- lets you combine Class A shares of multiple funds
      for purposes of calculating the sales charge.

To utilize: complete the appropriate section of your application, or contact
your financial representative or Signature Services to add these options (see
the back cover of this prospectus).

   
Group Investment Program A group may be treated as a single purchaser under the
accumulation and combination privileges. Each investor has an individual
account, but the group's investments are lumped together for sales charge
purposes, making the investors potentially eligible for reduced sales charges.
There is no charge, no obligation to invest (although initial aggregate
investments must be at least $250), and individual investors may terminate their
accounts at any time.
    

To utilize: contact your financial representative or Signature Services to find
out how to qualify, or consult the SAI (see the back cover of this prospectus).

CDSC waivers As long as Signature Services is notified at the time you sell, the
CDSC for either share class will generally be waived in the following cases:
o  to make payments through certain systematic withdrawal plans
o  to make certain distributions from a retirement plan
o  because of shareholder death or disability

To utilize: if you think you may be eligible for a CDSC waiver, contact your
financial representative or Signature Services, or consult the SAI.

Reinstatement privilege If you sell shares of a John Hancock fund, you may
reinvest some or all of the proceeds in the same share class of any John Hancock
fund within 120 days without a sales charge, as long as Signature Services is
notified before you reinvest. If you paid a CDSC when you sold your shares, you
will be credited with the amount of the CDSC. All accounts involved must have
the same registration.

To utilize: contact your financial representative or Signature Services.


                                                                YOUR ACCOUNT  19

Waivers for certain investors Class A shares may be offered without front-end
sales charges or CDSCs to various individuals and institutions, including:

o     government entities that are prohibited from paying mutual fund sales
      charges
o     financial institutions or common trust funds investing $1 million or more
      for non-discretionary accounts
o     selling brokers and their employees and sales
      representatives
o     financial representatives utilizing fund shares in
      fee-based investment products under agreement with John Hancock Funds
o     fund trustees and other individuals who are affiliated with these or other
      John Hancock funds
o     individuals transferring assets to a John Hancock fund from an employee
      benefit plan that has John Hancock funds
o     members of an approved affinity group financial
      services program
o     certain insurance company contract holders (one-year CDSC usually applies)
o     participants in certain retirement plans with at least 100 members
      (one-year CDSC applies)
   
o     current shareholders of Limited-Term Government Fund making additional
      investments in the fund with the proceeds from any non-John Hancock mutual
      fund, as long as that fund had sales charges and the investor paid them;
      investors must supply a copy of the redemption check or confirmation
      statement, and must remain invested in Limited-Term Government Fund for at
      least 15 days
    

To utilize: if you think you may be eligible for a sales charge waiver, contact
Signature Services or consult the SAI.

Selling shares in writing In certain circumstances, you will need to make your
request to sell shares in writing. You may need to include additional items with
your request, as shown in the table below. You may also need to include a
signature guarantee, which protects you against fraudulent orders. You will need
a signature guarantee if:
o     your address of record has changed within the past 30 days
o     you are selling more than $100,000 worth of shares
o     you are requesting payment other than by a check mailed to the address of
      record and payable to the registered owner(s)

You can generally obtain a signature guarantee from the following sources:
o     a broker or securities dealer
o     a federal savings, cooperative or other type of bank
o     a savings and loan or other thrift institution
o     a credit union
o     a securities exchange or clearing agency

A notary public CANNOT provide a signature guarantee.

- --------------------------------------------------------------------------------
TRANSACTION POLICIES

Valuation of shares The net asset value per share (NAV) for each fund and class
is determined each business day at the close of regular trading on the New York
Stock Exchange (typically 4 P.M. Eastern Time) by dividing a class's net assets
by the number of its shares outstanding.

Buy and sell prices When you buy shares, you pay the NAV plus any applicable
sales charges, as described earlier. When you sell shares, you receive the NAV
minus any applicable deferred sales charges.

Execution of requests Each fund is open on those days when the New York Stock
Exchange is open, typically Monday through Friday. Buy and sell requests are
executed at the next NAV to be calculated after your request is accepted by
Signature Services.

At times of peak activity, it may be difficult to place requests by phone.
During these times, consider using EASI-Line or sending your request in writing.

In unusual circumstances, any fund may temporarily suspend the processing of
sell requests, or may postpone payment of proceeds for up to three business days
or longer, as allowed by federal securities laws.

Telephone transactions For your protection, telephone requests may be recorded
in order to verify their accuracy. In addition, Signature Services will take
measures to verify the identity of the caller, such as asking for name, account
number, Social Security or other taxpayer ID number and other relevant
information. If appropriate measures are taken, Signature Services is not
responsible for any losses that may occur to any account due to an unauthorized
telephone call. Also for your protection, telephone transactions are not
permitted on accounts whose names or addresses have changed within the past 30
days. Proceeds from telephone transactions can only be mailed to the address of
record.

Exchanges You may exchange shares of one John Hancock fund for shares of the
same class of any other, generally without paying any additional sales charges.
The registration for both accounts involved must be identical. Class B shares
will continue to age from the original date and will retain the same CDSC rate
as they had before the exchange, except that the rate will change to the new
fund's rate if that rate is higher. A CDSC rate that has increased will drop
again with a future exchange into a fund with a lower rate.

To protect the interests of other investors in the fund, a fund may cancel the
exchange privileges of any parties that, in the opinion of the fund, are using
market timing strategies or making more than seven exchanges per owner or
controlling party per calendar year. A fund may also refuse any exchange order.
A fund may change or cancel its exchange policies at any time, upon 60 days'
notice to its shareholders.

Certificated shares Most shares are electronically recorded. If you wish to have
certificates for your shares, please write to Signature Services. Certificated
shares can only be sold by returning the certificates to Signature Services,
along with a letter of instruction or a stock power and a signature guarantee.

Sales in advance of purchase payments When you place a request to sell shares
for which the purchase money has not yet been collected, the request will be
executed in a timely fashion, but the fund will not release the proceeds to you
until your purchase payment clears. This may take up to ten business days after
the purchase.

- --------------------------------------------------------------------------------
DIVIDENDS AND ACCOUNT POLICIES

Account statements  In general, you will receive account statements as follows:
o     after every transaction (except a dividend reinvestment) that affects your
      account balance
o     after any changes of name or address of the registered owner(s)
o     in all other circumstances, every quarter

Every year you should also receive, if applicable, a Form 1099 tax information
statement, mailed by January 31.

Dividends The funds generally declare dividends daily and pay them monthly.
Short- and long-term capital gains, if any, are distributed annually, typically
after the end of a fund's fiscal year. Your dividends begin accruing the day
after payment is received by the fund and continue through the day your shares
are actually sold.

   
Dividend reinvestments Most investors have their dividends reinvested in
additional shares of the same fund and class. If you choose this option, or if
you do not indicate any choice, your dividends will be reinvested on the
dividend record date. Alternatively, you can choose to have a check for your
dividends mailed to you. However, if the check is not deliverable, your
dividends will be reinvested.
    


24  YOUR ACCOUNT
<PAGE>

Taxability of dividends As long as a fund meets the requirements for being a
tax-qualified regulated investment company, which each fund has in the past and
intends to in the future, it pays no federal income tax on the earnings it
distributes to shareholders.

   
Dividends you receive from a fund, whether reinvested or taken as cash, are
generally considered taxable. Dividends from a fund's long-term capital gains
are taxable as capital gains; dividends from other sources are generally taxable
as ordinary income. Some dividends paid in January may be taxable as if they had
been paid the previous December.
    

The Form 1099 that is mailed to you every January details your dividends and
their federal tax category, although you should verify your tax liability with
your tax professional.

Taxability of transactions Any time you sell or exchange shares, it is
considered a taxable event for you. Depending on the purchase price and the sale
price of the shares you sell or exchange, you may have a gain or a loss on the
transaction. You are responsible for any tax liabilities generated by your
transactions.

Small accounts (non-retirement only) If you draw down a non-retirement account
so that its total value is less than $1,000, you may be asked to purchase more
shares within 30 days. If you do not take action, your fund may close out your
account and mail you the proceeds. Alternatively, Signature Services may charge
you $10 a year to maintain your account. You will not be charged a CDSC if your
account is closed for this reason, and your account will not be closed if its
drop in value is due to fund performance or the effects of sales charges.

      for your first investment amount payable to "John Hancock Signature
      Services, Inc." Deliver your check and application to your financial
      representative or Signature Services.

Systematic withdrawal plan  This plan may be used for routine bill payments or
periodic withdrawals from your account. To establish:
o     Make sure you have at least $5,000 worth of shares in your account.
o     Make sure you are not planning to invest more money in this account 
      (buying shares during a period when you are also selling shares of the
      same fund is not advantageous to you, because of sales charges).
o     Specify the payee(s). The payee may be yourself or any other party, and
      there is no limit to the number of payees you may have, as long as they
      are all on the same payment schedule.
o     Determine the schedule: monthly, quarterly, semi-annually, annually or in
      certain selected months.
o     Fill out the relevant part of the account application. To add a systematic
      withdrawal plan to an existing account, contact your financial
      representative or Signature Services.

BUSINESS STRUCTURE

How the funds are organized Each John Hancock income fund is an open-end
management investment company or a series of such a company.

Each fund is supervised by a board of trustees, an independent body that has
ultimate responsibility for the fund's activities. The board retains various
companies to carry out the fund's operations, including the investment adviser,
custodian, transfer agent and others (see diagram). The board has the right, and
the obligation, to terminate the fund's relationship with any of these companies
and to retain a different company if the board believes it is in the
shareholders' best interests.

At a mutual fund's inception, the initial shareholder (typically the adviser)
appoints the fund's board. Thereafter, the board and the shareholders determine
the board's membership. The boards of the John Hancock income funds may include
individuals who are affiliated with the investment adviser. However, the
majority of board members must be independent.

The funds do not hold annual shareholder meetings, but may hold special meetings
for such purposes as electing or removing board members, changing fundamental
policies, approving a management contract or approving a 12b-1 plan (12b-1 fees
are explained in "Sales compensation").

Accounting compensation The funds compensate the adviser for performing tax and
financial management services. Annual compensation is not expected to exceed
0.02% of each fund's average net assets.

Portfolio trades In placing portfolio trades, the adviser may use brokerage
firms that market the fund's shares or are affiliated with John Hancock Mutual
Life Insurance Company, but only when the adviser believes no other firm offers
a better combination of quality execution (i.e., timeliness and completeness)
and favorable price.

Investment goals Except for Government Income Fund, High Yield Bond Fund and
Intermediate Maturity Government Fund, each fund's investment goal is
fundamental and may only be changed with shareholder approval.

Diversification All of the income funds are diversified.

- --------------------------------------------------------------------------------
SALES COMPENSATION

As part of their business strategies, the funds, along with John Hancock Funds,
pay compensation to financial services firms that sell the funds' shares.
These firms typically pass along a portion of this compensation to your
financial representative.

Compensation payments originate from two sources: from sales charges and from
12b-1 fees that are paid out of the funds' assets ("12b-1" refers to the federal
securities regulation that authorizes annual fees of this type). The 12b-1 fee
rates vary by fund and by share class, according to Rule 12b-1 plans adopted by
the funds. The sales charges and 12b-1 fees paid by investors are detailed in
the fund-by-fund information. The portions of these expenses that are reallowed
to financial services firms are shown on the next page.

Distribution fees may be used to pay for sales compensation to financial
services firms, marketing and overhead expenses and, for Class B shares,
interest expenses.

(1)   As of the most recent fiscal year end covered by each fund's financial
      highlights. These expenses may be carried forward indefinitely.

Initial compensation Whenever you make an investment in a fund or funds, the
financial services firm receives either a reallowance from the initial sales
charge or a commission, as described below. The firm also receives the first
year's service fee at this time.

Annual compensation Beginning with the second year after an investment is made,
the financial services firm receives an annual service fee of 0.25% of its total
eligible net assets. This fee is paid quarterly in arrears.

Financial services firms selling large amounts of fund shares may receive extra
compensation. This compensation, which John Hancock Funds pays out of its own
resources, may include asset retention fees as well as reimbursement for
marketing expenses.

MORE ABOUT RISK

A fund's risk profile is largely defined by the fund's principal securities and
investment practices. You may find the most concise description of each fund's
risk profile in the fund-by-fund information.

The funds are permitted to utilize -- within limits established by the trustees
- -- certain other securities and investment practices that have higher risks and
opportunities associated with them. To the extent that a fund utilizes these
securities or practices, its overall performance may be affected, either
positively or negatively. On the following pages are brief descriptions of these
securities and investment practices, along with the risks associated with them.
The funds follow certain policies that may reduce these risks.

As with any mutual fund, there is no guarantee that a John Hancock income fund
will earn income or show a positive total return over any period of time --
days, months or years.

- --------------------------------------------------------------------------------
TYPES OF INVESTMENT RISK

Correlation risk The risk that changes in the value of a hedging instrument will
not match those of the asset being hedged (hedging is the use of one investment
to offset the effects of another investment). Incomplete correlation can result
in unanticipated risks.

Credit risk The risk that the issuer of a security, or the counterparty to a
contract, will default or otherwise become unable to honor a financial
obligation.

Currency risk The risk that fluctuations in the exchange rates between the U.S.
dollar and foreign currencies may negatively affect an investment. Adverse
changes in exchange rates may erode or reverse any gains produced by foreign
currency-denominated investments, and may widen any losses.

Extension risk The risk that an unexpected rise in interest rates will extend
the life of a mortgage-backed security beyond the expected prepayment time,
typically reducing the security's value.

Interest rate risk The risk of market losses attributable to changes in interest
rates. With fixed-rate securities, a rise in interest rates typically causes a
fall in values, while a fall in rates typically causes a rise in values.

Leverage risk Associated with securities or practices (such as borrowing) that
multiply small index or market movements into large changes in value.

o     Hedged When a derivative (a security whose value is based on another
      security or index) is used as a hedge against an opposite position that
      the fund also holds, any loss generated by the derivative should be
      substantially offset by gains on the hedged investment, and vice versa.
      While hedging can reduce or eliminate losses, it can also reduce or
      eliminate gains.
o     Speculative To the extent that a derivative is not used as a hedge, the
      fund is directly exposed to the risks of that derivative. Gains or losses
      from speculative positions in a derivative may be substantially greater
      than the derivative's original cost.

   
Liquidity risk The risk that certain securities may be difficult or impossible
to sell at the time and the price that the seller would like. The seller may
have to lower the price, sell other securities instead, or forego an investment
opportunity, any of which could have a negative effect on fund management or
performance.
    

Management risk The risk that a strategy used by a fund's management may fail to
produce the intended result. Common to all mutual funds.

Market risk The risk that the market value of a security may move up and down,
sometimes rapidly and unpredictably. Market risk may affect a single issuer, an
industry, a sector of the bond market or the market as a whole. Common to all
stocks and bonds and the mutual funds that invest in them.

Natural event risk The risk of losses attributable to natural disasters, crop
failures and similar events.

Opportunity risk The risk of missing out on an investment opportunity because
the assets necessary to take advantage of it are tied up in less advantageous
investments.

Political risk The risk of losses attributable to government or political
actions, from changes in tax or trade statutes to governmental collapse and war.

Prepayment risk The risk that unanticipated prepayments may occur, reducing the
value of mortgage-backed securities.

Valuation risk The risk that a fund has valued certain of its securities at a
higher price than it can sell them for.
