Important Information

September 24,1998

Dear Fellow Shareholder:

I am writing to ask for your vote on an  important  matter that will affect your
investment in the John Hancock Sovereign U.S. Government Income Fund. 

You may be aware that in  addition to your Fund,  John  Hancock  Funds  offers a
similar U.S.  government  fund - the John Hancock  Government  Income Fund.  The
Government  Income  Fund  seeks to earn a high  level  of  current  income  with
preservation  of capital by investing  primarily in U.S.  government  and agency
securities.

After careful  consideration,  your Fund's Trustees have unanimously agreed that
merging your Fund into the John Hancock  Government Income Fund will offer you a
similar  investment  objective  and strategy  with lower  anticipated  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,


         Edward J. Boudreau, Jr.
         Chairman and CEO

Q: What are the benefits of merging the Sovereign U.S.  Govern-ment  Income Fund
into the Government Income Fund?

A:  Offering two similar U.S.  government  funds has made it more  difficult for
both  your  Fund and the  Government  Income  Fund to raise  assets  and  reduce
expenses.  Your Trustees  firmly  believe this merger will allow you to continue
pursuing a high level of income through investment in U.S. government and agency
securities at a lower overall anticipated operating expense.

The  Government  Income Fund's larger asset base after the merger,  coupled with
the adviser's plan to limit  management  fees to 0.50%, is expected to allow for
lower operating  expenses than your Fund has now.  Following the merger,  annual
fees are projected to be 1.01% for Class A  shareholders,  down from 1.14%,  and
1.76% for Class B shareholders,  down from 1.84%. These projected lower expenses
should  help keep more of your money  invested,  which often helps to bolster an
investment's total return over time.

Q: How does the  Government  Income  Fund's  strategy  compare  with that of the
Sovereign U.S. Government Income Fund?

A: The  Government  Income  Fund seeks to earn a high  level of  current  income
consistent with  preservation  of capital.  Your Fund seeks to provide as high a
level of income as is consistent with long-term  total return.  Both funds focus
on securities of varying maturities issued by the U.S. government,  its agencies
or instrumentalities. Unlike your Fund, the Government Income Fund can invest up
to 20% of its assets in U.S. dollar-denominated bonds of foreign governments as
noted  in  the  enclosed  prospectus.  This  investment  flexibility  makes  the
Government  Income Fund somewhat less  conservative  than your Fund,  due to the
increased  potential  risk  associated  with  these  securities.   However,  the
Government Income Fund applies a relatively  conservative  investment  approach,
which  attempts to minimize  these risks.  Keep in mind that this  approach also
allows the Government  Income Fund to seek higher current income than your Fund,
while still focusing on preservation of capital.

Q: How has the Government  Income Fund performed?  

A: Although past performance  does not guarantee future results,  the Government
Income  Fund has been a steady  performer  over the years.  The  Fund's  Class B
shares have posted  average  annual  returns of 4.69% over the past year,  5.12%
over the past five years and 7.30% over the past ten years,  with maximum  sales
charges,  as of June 30, 1998. As of this ending date, the Fund's Class A shares
have posted  average  annual total returns of 5.53% for the year and 7.54% since
inception on  September  30, 1994,  with maximum  sales  charges.* To review the
Government  Income  Fund in greater  detail,  please  refer to the John  Hancock
Income Funds prospectus and the Government Income Fund's most recent shareholder
report, both 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  11,  1998 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 Sovereign U.S. Government Fund shares will be
exchanged for  Government  Income Fund shares,  using the Funds' net asset value
share prices,  excluding  sales charges,  at the close of trading on December 4,
1998. 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 1998 tax return.

*Performance  figures  assume all  distributions  are  reinvested  and reflect a
maximum  sales  charge on Class A shares of 4.5% and the  applicable  contingent
deferred  sales charge on Class B shares.  The CDSC  declines  annually  between
years  1-6  according  to the  following  schedule:  5, 4, 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.

                       NOTICE OF MEETING OF SHAREHOLDERS
                        SCHEDULED FOR NOVEMBER 11, 1998

This is the formal agenda for your fund's shareholder meeting. It tells you what
matters will be voted on and the time and place of the meeting, in case you want
to attend in person.

To the shareholders of John Hancock Sovereign U.S. Government Income Fund:

A  shareholder  meeting  for your  fund will be held at 101  Huntington  Avenue,
Boston, Massachusetts on Wednesday, November 11, 1998 at 9:00 a.m., Eastern
Time, to consider the following:

1.       A proposal to approve an Agreement and Plan of Reorganization between
         your fund and John Hancock Government Income Fund.  Under this
         Agreement, your fund would transfer all of its assets to Government
         Income Fund in exchange for shares of Government Income Fund. These
         shares would be distributed proportionately to you and the other
         shareholders of your fund.  Government Income Fund would also assume
         your fund's liabilities.  Your board of trustees recommends that you
         vote FOR this proposal.

2.       Any other business that may properly come before the meeting.

Shareholders  of record as of the close of  business on  September  16, 1998 are
entitled to vote at the meeting and any related follow-up meetings.

Whether or not you expect to attend the meeting,  please complete and return the
enclosed proxy card. If  shareholders  do not return their proxies in sufficient
numbers,  your  fund  will  incur  the  cost of  extra  solicitations,  which is
indirectly borne by you and other shareholders.

                                 By order of the board of trustees,
                                 Susan S. Newton

         to their holdings on the reorganization date.

         o  Government  Income Fund will issue Class B shares to your fund in an
         amount equal to the value of your fund's  Class B shares.  These shares

Why Your Fund's Trustees are Recommending the Reorganization

The trustees of your fund believe that reorganizing your fund into a larger fund

The Funds' Expenses

Shareholders of both funds pay various expenses,  either directly or indirectly.
The  first  two  expense  tables  appearing  below  show  the  expenses  for the
twelve-month period ended May 31, 1998, adjusted to reflect any changes.  Future
expenses may be greater or less.  The examples  contained in each expense  table
show what you would pay if you  invested  $1,000 over the various  time  periods
indicated.  Each example  assumes that you reinvested all dividends and that the
average annual return was 5%. The examples are for comparison  purposes only and
are not a  representation  of either fund's actual  expenses or returns,  either
past or future.

Pro Forma Expense Table

The next expense table shows the pro forma  expenses of  Government  Income Fund
assuming  that a  reorganization  with your fund  occurred on May 31, 1998.  The
expenses shown in the table are based on fees and expenses  incurred  during the
twelve  months ended May 31, 1998,  adjusted to reflect any changes.  Government
Income Fund's actual  expenses after the  reorganization  may be greater or less
than those shown.  The example  contained in the pro forma  expense  table shows
what you would pay on a $1,000 investment if the  reorganization had occurred on
May 31, 1998. The example assumes that you reinvested all dividends and that the
average annual return was 5%. The pro forma example is for  comparison  purposes
only and is not a representation  of Government Income Fund's actual expenses or
returns, either past or future.

         for  12b-1 and  transfer  agent  expenses).  Without  this  limitation,
         management  fees would be 0.62% for each class and total fund operating

The Reorganization

         o        The reorganization is scheduled to occur at 5:00 p.m., Eastern
                  Time,  on  December  4, 1998,  but may occur on any later date
                  before June 1, 1999. Your fund will transfer all of its assets
                  to Government Income Fund.  Government Income 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.


                                       13
<PAGE>

         o        Government Income 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.  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 Government
                  Income Fund.

         o        Government Income 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.  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 Government
                  Income 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 its average daily net assets:

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

Although at all asset  levels the advisory fee rates paid by your fund are lower
than the rates paid by Government  Income Fund,  the adviser has agreed to limit
Government Income Fund's management fee to an annual rate of 0.50% of the Fund's
average daily net assets if Sovereign U.S. Government Income Fund's shareholders
approve the Reorganization.

In addition to the same  advisory  fee rates,  Government  Income  Fund's  other

                                       15

<PAGE>

expenses of 0.21%,  as well as its pro forma other expenses of 0.26%,  are lower
than your fund's other expenses of 0.34%. Furthermore,  Government Income Fund's
12b-1 fee rate of 0.25% for Class A shares is below your fund's Class A fee rate
of 0.30%.  Both funds pay the same  Class B 12b-1 fee rate of 1.00%.  Government
Income  Fund's  current  annual Class A expense ratio (equal to 1.10% of average
net assets) is lower than your fund's  current  Class A expense  ratio (equal to
1.14% of average net assets) and its current annual Class B expense ratio (equal
to 1.85% of average  net  assets) is higher  than your  fund's  current  Class B
expense ratio (equal to 1.84% of average net assets). However, Government Income
Fund's  Proforma  total annual  operating  expenses for both Class A and Class B
shares are  expected  to be less than your  fund's  current  Class A and Class B
total annual operating expenses.

                                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 shows that the
risks affecting each fund are similar.

- --------------------------------------------------------------------------------
           Both Sovereign U.S. Government and Government Income Funds
- --------------------------------------------------------------------------------
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 also  subject to
                    the risk  that the  issuer of a  security  will  default  or
                    otherwise fail to meet its obligations.
- ------------------- ------------------------------------------------------------
Foreign securities  Government Income Fund's  investments in foreign securities 
and currency risks  are subject to the risks of adverse foreign  government
                    actions,  political instability or a lack of adequate and 
                    accurate information.
- ------------------- ------------------------------------------------------------
Risks of            Each fund's 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.

- --------------------------------------------------------------------------------
           Both Sovereign U.S. Government and Government Income Funds
- ------------------- ------------------------------------------------------------
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 typically
instruments         cause the value of these instruments to rise.  These
including           instruments are also subject to the risk that the issuer
asset-backed and    will default or otherwise fail to meet its obligations.  In
mortgage-backed     addition, mortgage-backed securities are subject to the risk
securities          that the life of the security will be extended beyond its
                    expected repayment time.  This 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. 
- ------------------- ------------------------------------------------------------
Risks of            Most derivative instruments involve leverage, which
derivative          increases market risks.  Leverage magnifies gains and losses
instruments,        on derivatives relative to changes in the value of
including           underlying assets.  If a derivative is used for hedging
financial           purposes, changes in the value of the derivative may not

                       PROPOSAL TO APPROVE THE AGREEMENT
                           AND PLAN OF REORGANIZATION

Description of Reorganization

You 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:

                                       17
<PAGE>



         o        The reorganization is scheduled to occur at 5:00 p.m.,
                  Eastern time, on December 4, 1998, but may occur on any
                  later date before June 1, 1999.  Your fund will transfer all
                  of its assets to Government Income Fund and Government
                  Income Fund will assume all of your fund's liabilities.
                  This will result in the addition of your fund's assets to
                  Government Income 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        Government Income 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 Government Income Fund.

         o        Government Income 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 Government Income 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,   shareholders   may  be  better  served  by  a  fund  offering   greater
diversification.  Government  Income Fund has a larger asset size than your fund
and may invest in a broader range of debt securities  including those of foreign
issuers.  Combining the funds' assets into a single  investment  portfolio  will
allow your fund's  shareholders  to  diversify  their  investments  to a greater
degree than may be possible through your fund alone. Greater  diversification is
expected to benefit the

                                       18

<PAGE>

shareholders  of your fund  because it may reduce the  negative  effect that the
adverse  performance  of any one  security  or  security  type  may  have on the
performance of the entire portfolio.

Second,  Government  Income Fund Class A shares have performed  better than your
fund over the past 1 and 3 year periods and Class B shares have performed better
than your fund over the past 1, 3, and 5 year  periods.  While past  performance
cannot predict future results,  the trustees believe that Government Income Fund
is better  positioned  than your fund to continue to  generate  strong  returns,
because of its superior  diversification  and greater flexibility to choose from
among a broader range of investment opportunities.

Third,  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.

Fourth,  because  John  Hancock  Funds has offered two funds with  substantially
similar  investment  characteristics  simultaneously,  it has been  increasingly
difficult to attract assets to your fund.

Fifth,  the Government  Income Fund shares received in the  reorganization  will
provide your fund's  shareholders  with  substantially  the same investment at a
comparable level of risk.

The  board  of  trustees  of  Government   Income  Fund   considered   that  the
reorganization  presents an excellent  opportunity for Government Income Fund to
acquire  investment  assets without the  obligation to pay  commissions or other
transaction costs that are normally  associated with the purchase of securities.
The trustees believe that Government  Income Fund shareholders will also benefit
from  improved  diversification  as a  result  of  the  reorganization.  Because
Government  Income Fund is a larger fund than your fund,  the trustees feel that
the  addition  of  your  fund's  assets  will  improve  the  diversification  of
Government  Income  Fund's  overall  portfolio.  This  opportunity  provides  an
economic benefit to Government  Income Fund and its  shareholders.  The trustees
also  considered the fact that the  management fee of Government  Income Fund is
higher  than the  management  fee of  Sovereign  U.S.  Government  Income  Fund.
However,  if Sovereign U.S.  Government Income Fund's  shareholders  approve the
Reorganization,  the  adviser  has  agreed  to limit  Government  Income  Fund's
management  fee to an  annual  rate of 0.50% of the  fund's  average  daily  net
assets.

The boards of  trustees of both funds also  considered  that the adviser and the
funds' distributor will also benefit from the reorganization.  For example,  the


                                       19

<PAGE>

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 your fund are lower than the rates
paid by  Government  Income  Fund.  However,  the  adviser  has  agreed to limit
Government Income Fund's management fee to an annual rate of 0.50% of the Fund's
average daily net assets if Sovereign U.S. Government Income Fund's shareholders
approve the Reorganization.

In addition to the same  advisory  fee rates,  Government  Income  Fund's  other
expenses of 0.21%,  as well as its pro forma other expenses of 0.26%,  are lower
than your fund's other expenses of 0.34%. Furthermore,  Government Income Fund's
12b-1 fee rate of 0.25% for Class A shares is below your fund's Class A fee rate
of 0.30%.  Both funds pay the same  Class B 12b-1 fee rate of 1.00%.  Government
Income  Fund's  current  annual Class A expense ratio (equal to 1.10% of average
net assets) is lower than your fund's  current  Class A expense  ratio (equal to
1.14% of average net assets) and its current annual Class B expense ratio (equal
to 1.85% of average  net  assets) is higher  than your  fund's  current  Class B
expense ratio (equal to 1.84% of average net assets). However, Government Income
Fund's  proforma  total  annual  operating  expenses for both Class A shares and
Class B shares are  expected  to be less than your  fund's  current  Class A and
Class B total annual operating expenses.

Your fund has not increased its asset size.  The trustees do not believe,  given
your fund's current size and historical growth rate, that your fund will grow to
an asset size that would allow your fund to realize the benefits of economies of
scale,  including better control over expenses. The trustees also do not believe
that  your  fund  will  reach  an asset  size  which  will  allow  your  fund to
significantly broaden the diversification of its investment portfolio.

Comparative Performance.  The trustees also took into consideration the
relative performance of your fund and Government Income Fund.

Unreimbursed Distribution and Shareholder Service Expenses

The boards of trustees of your fund and Government  Income 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 Government Income Fund's Rule 12b-1 Plans. However,
the maximum amounts payable annually under  Government  Income 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 Government Income
Fund.  The  table  shows  both  the  dollar  amount  of these  expenses  and the
percentage of each class' average net assets that they represent.

</TABLE>


If the  reorganization  had taken place on May 31, 1998,  the pro forma combined
unreimbursed  expenses of  Government  Income  Fund's Class A and Class B shares
would have been higher than if no  reorganization  had  occurred.  Nevertheless,
Government  Income  Fund's  assumption  of your fund's  unreimbursed  Rule 12b-1
expenses will have no immediate  effect upon the payments made under  Government
Income  Fund's Rule 12b-1 Plans.  Their  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

                                       21
<PAGE>

shareholder service expenses for Class B shares over an extended period of time.
However,  if Government  Income 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 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)(C)  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  Government  Income  Fund as
                  described above or (2) the distribution by your fund of Growth
                  and Income Fund shares to your fund's shareholders;

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

         o        The basis of the assets of your fund  acquired  by  Government
                  Income  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 Government Income Fund will include your fund's tax holding
                  period for those assets;

         o        The  shareholders  of your fund will not recognize a gain or a
                  loss upon the exchange of all their shares of your fund solely

                                       22
<PAGE>

                  for   Government   Income   Fund   shares   as   part  of  the
                  reorganization;

         o        The basis of  Government  Income 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

         o        The tax holding  period of the  Government  Income Fund shares
                  you receive will include the tax holding  period of the shares
                  of your fund surrendered in the exchange, provided that 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.  If your shares are represented by one or more
share certificates before the reorganization date, you must either surrender the
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 Government Income
Fund  shares.  Shareholders  may not redeem or transfer  Government  Income Fund
shares received in the  reorganization  until they have  surrendered  their fund
share  certificates or delivered an Affidavit.  Government  Income 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  Government  Income 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 Government  Income 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

                                       23
<PAGE>

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).

Termination  of  Agreement.  The  board  of  trustees  of  either  your  fund or
Government  Income 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.  Government Income 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
$250,410 in total.

                                 CAPITALIZATION

The  following  table sets forth the  capitalization  of each fund as of May 31,
1998,  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  1.0724  Class A  Government  Income Fund shares  being
issued  for each  Class A share of your fund and  approximately  1.0724  Class B
Government  Income 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.  This is due to
changes in the  market  value of the  portfolio  securities  of both  Government
Income  Fund and your fund  between May 31,  1998 and the  reorganization  date,
changes in the amount of  undistributed  net investment  income and net realized
capital  gains of  Government  Income  Fund and your  fund  during  that  period
resulting from income and distributions,  and changes in the accrued liabilities
of Government Income Fund and your fund during the same period.

It is  impossible  to  predict  how many  Class A shares  and  Class B shares of
Government Income 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  Government  Income  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 Government
Income Fund,  including the independent  trustees,  approved the reorganization.
They  also  determined  that the  reorganization  was in the best  interests  of
Government  Income  Fund and that the  interests  of  Government  Income  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

                                       26

<PAGE>

(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)
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 $100,360.

Revoking Proxies

A Sovereign  U.S.  Government  Income 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

                                       27
<PAGE>

         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.

Outstanding Shares and Quorum

As of  September  16,  1998,  _______ and _______  Class A and Class B shares of
beneficial  interest of your fund were outstanding.  Only shareholders of record
on September 16, 1998 (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.

                                       28

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.

         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.

                        OWNERSHIP OF SHARES OF THE FUNDS

To the  knowledge of the fund,  as of August 14, 1998, no person owned of record
or beneficially 5% or more of the outstanding Class A and Class B shares of your
fund or of the  outstanding  Class A shares of  Government  Income  Fund.  As of
August 14, 1998,  the following  person owned of record or  beneficially  5% or
more of the outstanding class B shares of Government Income Fund.

                                    EXHIBIT A

                      AGREEMENT AND PLAN OF REORGANIZATION

THIS AGREEMENT AND PLAN OF  REORGANIZATION  (the  "Agreement") is made this 11th
day of August,  1998,  by and between John Hancock  Government  Income Fund (the
"Acquiring Fund"), a series of John Hancock Bond Trust, a Massachusetts business
trust (the "Trust II"), and John Hancock  Sovereign U.S.  Government Income Fund
(the  "Acquired   Fund"),  a  series  of  John  Hancock   Strategic   Series,  a
Massachusetts  business trust (the "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 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 4, 1998 (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")

                                       1
<PAGE>

       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 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.

                                       2
<PAGE>

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 Trust, 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 Trust.

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  4, 1998 or such  other date on or
       before June 30, 1999 as the parties may agree.  The Closing shall be held
       as of 5:00  p.m.  at the  offices  of the  Trust  II and the  Trust,  101
       
                                       3
<PAGE>

       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 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,  1999,  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.

4.   REPRESENTATIONS AND WARRANTIES

4.1    The Trust on behalf of the Acquired  Fund  represents,  warrants  and  
       covenants  to the  Acquiring  Fund as follows:

                                       4
<PAGE>

    (a) The Trust is a business trust,  duly organized,  validly existing and in
        good standing under the laws of The  Commonwealth of  Massachusetts  and
        has the power to own all of its  properties  and assets and,  subject to
        approval by the  shareholders  of the  Acquired  Fund,  to carry out the
        transactions  contemplated by this Agreement.  Neither the Trust nor the
        Acquired Fund is required to qualify to do business in any  jurisdiction
        in which  it is not so  qualified  or where  failure  to  qualify  would
        subject it to any material  liability or  disability.  The Trust has all
        necessary  federal,  state  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 Investment  Company Act of 1940, as amended (the "1940
        Act"),  is in full force and effect.  The Acquired Fund is a diversified
        series of the Trust;

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

    (d) Except as otherwise  disclosed in writing and accepted by the  Acquiring
        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 Acquired Fund or any of
        the Acquired  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 Acquired  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 Acquired Fund's business
        or its ability to consummate the transactions herein contemplated;

    (e) The Acquired Fund has no material  contracts or other commitments (other
        than this Agreement or agreements for the purchase of securities entered
        into  in the  ordinary  course  of  business  and  consistent  with  its
        obligations  under this Agreement) which will not be terminated  without

        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;

       satisfactory to the Trust on behalf of the Acquired Fund and the Trust II
       on behalf of the  Acquiring  Fund,  substantially  to the effect that for
       federal income tax purposes:

    (a) The  acquisition  by the  Acquiring  Fund  of all of the  assets  of the
        Acquired  Fund solely in exchange  for the  issuance of  Acquiring  Fund
        Shares to the Acquired  Fund and the  assumption  of all of the Acquired
        Fund Liabilities by the Acquiring Fund,  followed by the distribution by
        the Acquired  Fund, in  liquidation  of the Acquired  Fund, of Acquiring
        Fund Shares to the  shareholders  of the  Acquired  Fund in exchange for
        their  shares  of  beneficial  interest  of the  Acquired  Fund  and the
        termination of the Acquired  Fund,  will  constitute a  "reorganization"

                                       12

<PAGE>

        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
        transfer of all of its assets to the  Acquiring  Fund solely in exchange
        for the issuance of Acquiring  Fund Shares to the Acquired  Fund and the
        assumption  of all of the Acquired  Fund  Liabilities  by the  Acquiring
        Fund; and (ii) the  distribution  by the Acquired Fund of such Acquiring
        Fund Shares to the shareholders of the Acquired Fund;

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

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

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

    (f) The  shareholders  of the Acquired Fund will not recognize  gain or loss
        upon the exchange of all of their shares of  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

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

The  Trust  II and the  Trust  agree to make and  provide  representations  with
respect to the Acquiring  Fund and the Acquired  Fund,  respectively,  which are
reasonably  necessary  to  enable  Hale  and  Dorr  LLP to  deliver  an  opinion
substantially  as set  forth in this  Paragraph  8.6.  Notwithstanding  anything
herein  to the  contrary,  neither  the  Trust  nor the  Trust II may  waive the
conditions set forth in this Paragraph 8.6.

11.1   This Agreement may be terminated by the mutual agreement of the Trust II,

       Fund.  In  addition,  either  party  may at  its  option  terminate  this

        warranty,  covenant or agreement  contained herein to be performed at or

        shareholders.

11.2   In the event of any such  termination,  there shall be no  liability  for
       damages on the part of the Trust II, the Acquiring  Fund,  the Trust,  or

effect of changing  the  provisions  regarding  the method for  determining  the
number of Acquiring Fund Shares to be received by the Acquired Fund shareholders
under this Agreement to the detriment of such shareholders without their further
approval;  provided that nothing contained in this Article 12 shall be construed
to prohibit the parties from amending this Agreement to change the Closing Date.

Overview

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

FUND INFORMATION KEY

Concise fund-by-fund descriptions begin on the next page. Each description
provides the following information:

[Clip Art] Goal and strategy The fund's particular investment goals and the
strategies it intends to use in pursuing those goals.

[Clip Art] Portfolio securities The primary types of securities in which the
fund invests. Secondary investments are described in "More about risk" at the
end of the prospectus.

[Clip Art] Risk factors The major risk factors associated with the fund.

[Clip Art] Portfolio management The individual or group designated by the
investment adviser to handle the fund's day-to-day management.

[Clip Art] Expenses The overall costs borne by an investor in the fund,
including sales charges and annual expenses.

[Clip Art] Financial highlights A table showing the fund's financial performance
for up to ten years, by share class. A bar chart showing total return allows you
to compare the fund's historical risk level to those of other funds.

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 $30 billion in assets.



<PAGE>

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
27. 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.

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

(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   CLASS C: N/A
- --------------------------------------------------------------------------------

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 27.

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.

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. Because no Class C shares were issued or outstanding during the past
year, Class C expenses are based on Class B expenses. Future expenses may be
greater or less.

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%.

  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
27. 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.

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 assets may be invested in 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 75% of
assets 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

o cash and cash-equivalents

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 27. 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.

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
27. 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.

Strategic Income Fund

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

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 27. 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.

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. Because no Class C shares were issued or outstanding during the past
year, Class C expenses are based on Class B expenses. Future expenses may be
greater or less.

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             $67         $84           $112      $182

    Assuming no redemption       $17         $54            $92      $182

 Class C shares

    Assuming redemption
    at end of period             $27         $54            $92      $201

    Assuming no redemption       $17         $54            $92      $201

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.

CHOOSING A SHARE CLASS


All John Hancock income funds offer two classes of shares, Class A and Class B.
In addition, Class C shares are available for High Yield Bond Fund and Strategic
Income Fund. Each class has its own cost structure as outlined below, allowing
you to choose the one that best meets your requirements. For more details, see
"How sales charges are calculated." Your financial representative can help you
decide which share class is best for you.


- --------------------------------------------------------------------------------
 Class A - for all funds
- --------------------------------------------------------------------------------


  o Front-end sales charges. There are several ways to reduce these charges,
    described under "Sales charge reductions and waivers" on the following page.


  o Lower annual expenses than Class B and Class C shares.

- --------------------------------------------------------------------------------
 Class B - for all funds
- --------------------------------------------------------------------------------

  o No front-end sales charge; all your money goes to work for you right away.

  o Higher annual expenses than Class A shares.

  o A contingent deferred sales charge that declines from 3% over four years for
    Intermediate Maturity Government Fund, and from 5% over 6 years for all
    other income funds.


  o Automatic conversion to Class A shares after five years for Intermediate
    Maturity Government Fund and after eight years for all other income funds,
    thus reducing future annual expenses.

- --------------------------------------------------------------------------------
 Class C - for selected funds
- --------------------------------------------------------------------------------


Applies to High Yield Bond Fund and Strategic Income Fund.


  o No front-end sales charge; all your money goes to work for you right away.

  o Higher annual expenses than Class A shares.

  o A 1% contingent deferred sales charge on shares sold within one year of
    purchase.

  o No automatic conversion to Class A shares, so the fund's annual expenses
    continue at the same level throughout the life of your investment.

For actual past expenses of Class A and Class B shares, see the fund-by-fund
information earlier in this prospectus.

It is presently the policy of Signature Services not to accept any order of
$100,000 or more for Class B shares or any order of $1 million or more for Class
C shares. In these circumstances it would be more beneficial for the investor to
purchase Class A shares.

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. 

Class C 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) of 1% on shares you sell within one year of purchase. 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.

CDSC calculations are based on the number of shares involved, not on the value
of your account. Each time you place a request to sell shares we will first sell
any shares in your account that carry no CDSC. 

For purposes of this CDSC, all purchases made during a calendar month are

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. Retirement plans investing $1 million in Class B
  shares may add that value to Class A purchases to calculate charges.


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 or
consult the SAI (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 investments must
total at least $250), and individual investors may close 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 each 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


o to purchase a John Hancock Declaration annuity


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


                                                                YOUR ACCOUNT  17
<PAGE>

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.

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


o selling brokers and their employees and sales representatives

o financial representatives utilizing fund shares in fee-based investment
  products under signed 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 from an employee benefit plan into a John
  Hancock fund

o certain insurance company contract holders (one-year CDSC usually applies)

o participants in certain retirement plans with at least 100 eligible
  employees(one-year CDSC applies)


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)


The signature guarantee must be from a member of the Signature Guarantee
Medallion Program (generally, a broker or securities dealer). We may refuse any
other source. 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 received 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 and Class
C 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.


22  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.

Consequently, 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.

- --------------------------------------------------------------------------------
ADDITIONAL INVESTOR SERVICES

Monthly Automatic Accumulation Program (MAAP) MAAP lets you set up regular
investments from your paycheck or bank account to the John Hancock fund(s) of
your choice. You determine the frequency and amount of your investments, and you
can terminate your program at any time. To establish:

o Complete the appropriate parts of your account application.

o If you are using MAAP to open an account, make out a check ($25 minimum) 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.

including Traditional and Roth IRAs, SIMPLE IRAs, SIMPLE 401(k)s, SEPs, 401(k)s,
money purchase pension and profit-sharing plans. Using these plans, you can

minimum investment of $250 or, for some group plans, no minimum investment at
all. To find out more, call Signature Services at 1-800-225-5291.

- --------------------------------------------------------------------------------
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 and Class C
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.


Class C shares Class C shares began operations during the 1997 fiscal year.
Therefore, there are no unreimbursed expenses to report.


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 during periods
of falling interest rates, 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.


Year 2000 risk The risk that the funds' operations could be disrupted by year
2000-related computer system problems. Although the adviser and the funds'
service providers are taking steps to address this issue, there may still be
some risk of adverse effects. Common to all mutual funds.

===============================CHAIRMAN'S MESSAGE===============================

DEAR FELLOW SHAREHOLDERS:

During the last decade, investors have become used to seeing stock market
returns averaging 15% or so each year. In the past three years, the stock market
has treated us to a record run, producing annual returns in excess of 20%.

      After such a long and remarkable performance, many began this year
wondering what the market would do for an encore in 1998. The answer so far has
been more of the same, even with the recent increase in volatility caused by
tremors from Asia. This achievement continues to bolster many investors'
convictions that the market will produce these results forever, or, in the worst
case, that market declines will always be short-lived. While the economy remains
solid and the environment favorable, history and reason tell us it's a highly
unlikely scenario.

      This doesn't mean we know what the market will do next, or that it's
riding for a fall. But after such a run, even in this "new era" of strong
economic growth with low inflation, we believe it would be wise for investors to
set more realistic expectations. As we've said before, markets do indeed move in
two directions. Over the long term, the market's historical results have been
more in the 10% per year range, which is still a solid result, considering it
has been produced despite wars, depressions and other social upheavals along the
way.

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

Officer, flush right, next to third paragraph.]
- --------------------------------------------------------------------------------

      In addition to adjusting, or at least re-examining, expectations, now
could also be a good time to review with your investment professional how your
assets are diversified, perhaps with an eye toward a more conservative approach.
Stocks, especially with their outsized gains of the last three years, might have
grown to represent a larger piece of your portfolio than you had originally
intended, given your objectives, time horizon and risk level.

      At John Hancock Funds, our goal is to help you reach your financial
objectives and maintain wealth. One way we can do that is by helping you keep
your feet on the ground as you pursue your dreams.

Sincerely,


/s/ Edward J. Boudreau, Jr.

                     U.S. bond market takes breather in '98,
                              after rallying in '97

Over the past year, most of the action in the U.S. bond market came during the
summer and fall of 1997, when bonds rallied as inflation remained low even
though economic growth was strong. The Asian financial crisis added further
momentum, sending investors fleeing to safe havens like U.S. Treasuries and
setting off global deflation (or falling prices) that helped eliminate lingering
inflation fears here. As bond prices rose, yields on 30-year Treasuries fell
from 6.90% on May 31, 1997, to 5.93% by year end. But by mid-January the rally
was over. For the rest of the winter and spring, bond yields stayed in a narrow
range, buffeted back and forth by the opposing forces of global deflation and
strong domestic economic growth. Yields on 30-year Treasuries hovered between
6.12% and 5.69%.

      As conditions changed, so did the market leaders. During the rally in
1997, Treasuries were the best place to be since they are the most sensitive to
changes in interest rates. Longer-term Treasuries, whose yields reflect
inflation expectations, did especially well. All that changed, however, in
January. With bond prices staying relatively stable, the biggest gainers were
spread securities -- like mortgage bonds and U.S. government agency bonds --
that offer a slight yield advantage over Treasuries. For the year ended May 31,
1998, the Lehman Brothers Treasury Composite Index returned 11.29%, compared to
9.68% for the Lehman Brothers Mortgage-Backed Securities Fixed-Rate Index.

bonds had more of a bumpy ride. Foreign government bonds, which had tumbled
following the Asian crisis, recovered in early 1998. But in late spring, signs
of increasing credit problems in Asia and a decline in U.S. exports to the
region caused them to retreat again.

      John Hancock Government Income Fund weathered these changes well. For the
year ended May 31, 1998, the Fund's Class A and Class B shares had total returns
of 10.82% and 10.01%, respectively, at net asset value. Keep in mind that your
net asset value return will be different from this performance if you were not
invested in the Fund for the entire period and did not reinvest all
distributions. By comparison, the average general U.S. government income fund
returned 10.46%, according to Lipper Analytical Services, Inc.1 For longer-term
performance information, please see pages six and seven.

Fine-tuning asset allocation

The Fund picked up a little ground in several different places. We benefited
from a sizable stake in 10-year and 30-year Treasuries, which outperformed
spread securities early on, as well as shorter-maturity Treasuries throughout
the period. We also had a slightly longer duration than our peers. Duration
measures how sensitive a bond's price is to changes in interest rates. The
longer a bond's duration, the more its price will rise as interest rates fall --
or fall as interest rates rise. As interest rates came down in 1997, the Fund's
longer duration gave it more opportunity for price gains. The Fund's duration,
which began the period at five years, stayed around 5.4 years for most of the
period. Finally, we picked up some extra yield in 1998 by increasing our stakes
in bonds issued by U.S. government agencies and foreign governments.

      Among the U.S. government agencies we owned were mortgage-backed
securities. We boosted our stake in mortgage bonds to 37%, up from 33% at the
end of November. Our main focus was GNMAs with 7.5% and 7% coupons (or stated
interest rates). We pruned our stake in mortgage bonds with coupons of 8% or
higher as interest rates fell and prepayment concerns mounted during December
and early January. Prepayments occur when homeowners pay off their existing
mortgage loans before their due dates and refinance at lower prevailing rates.
We held onto our 11% stake in short-term and long-term collateralized mortgage
obligations, known as CMOs, which carried less prepayment risk than our
traditional mortgage securities. CMOs separate the cash flows of mortgage pools
into various classes with different maturities. Our stake in bonds issued by
other U.S. government agencies also held relatively steady at 10% of net assets.

      In the foreign government sector, our timing worked out well. We had pared
back on foreign government bonds shortly before the Asian crisis. Then, in 1998,
we rebuilt our stake by buying on weakness. Our main addition was to

our existing investment in bonds issued by Hydro-Quebec, the largest electric
utility in the Americas. As Quebec secession concerns again resurfaced, prices
on bonds backed by the province fell and yields rose. Since our purchase, fears
have abated and prices have again risen.

A look ahead

We believe there are two possible scenarios ahead. If the Asian situation
continues to deteriorate, we expect the U.S. economy to slow, interest rates to
fall and bond prices to rally. If Asia's problems begin to fade and U.S. wage
pressures accelerate, we expect a rise in short-term interest rates. To
determine which direction we're headed, we'll be closely watching the Asian
banking system, commodity prices, U.S. wages and corporate earnings growth.
Although it's hard to know what the outcome will be, the first scenario
currently seems most likely. Just recently, we've seen Japanese banks
acknowledging worse non-performing loans, more credit strains from Asian
companies and a noticeable decline in U.S. exports to the Pacific rim.

      We're cautiously optimistic about the bond market's prospects in the next
six months. If Asia's problems continue to multiply, bond investors will start
anticipating a slowdown in the economy. Once this happens, we expect interest
rates to move modestly lower and U.S. bond prices to rally. To position the Fund
for this possibility, we've already lengthened duration slightly to 5.6 years by
selling some of our shorter-maturity Treasuries and buying more 10-year and
30-year Treasuries. If a rally looks increasingly likely, we may increase
duration a bit more. Overall, we expect few dramatic changes in the bond market.
As long as the market continues to remain stable, we'll keep or build our stake
in mortgage and foreign government bonds to take advantage of the extra yield
they offer.

"Overall, we expect few dramatic changes in the bond market."

- --------------------------------------------------------------------------------
                              A LOOK AT PERFORMANCE
- --------------------------------------------------------------------------------

The tables on the right show the cumulative total returns and the average annual
total returns for the John Hancock Government Income Fund. Total return measures
the change in value of an investment from the beginning to the end of a period,
assuming all distributions were reinvested.

For Class A shares, total return figures include a maximum applicable sales
charge of 4.5%. Prior to May 15, 1995, the maximum applicable sales charge for
Class A shares was 4.75%. Class B performance reflects a maximum contingent
deferred sales charge (maximum 5% and declining to 0% over six years).

All figures represent past performance and are no guarantee of future results.
Keep in mind that the total return and share price of the Fund's investments
will fluctuate. As a result, your Fund's shares may be worth more or less than
their original cost, depending on when you sell them. Please read your
prospectus carefully before you invest or send money.

repurchased during the last three periods, along with the corresponding dollar
value.

==========================NOTES TO FINANCIAL STATEMENTS=========================

                   John Hancock Funds - Government Income Fund

NOTE A -
ACCOUNTING POLICIES

John Hancock Bond Trust (the "Trust") is a diversified open-end management
investment company, registered under the Investment Company Act of 1940, as
amended. The Trust consists of three series: John Hancock Government Income Fund
(the "Fund"), John Hancock High Yield Bond Fund and John Hancock Intermediate
Maturity Government Fund. The other two series of the Trust are reported in
separate financial statements. The investment objective of the Fund is to earn a
high level of current income consistent with preservation of capital by
investing primarily in securities that are issued or guaranteed as to principal
and interest by the U.S. government, its agencies or instrumentalities ("U.S.
government securities").

      The Trustees have authorized the issuance of multiple classes of shares of
the Fund, designated as Class A and Class B shares. The shares of each class
represent an interest in the same portfolio of investments of the Fund and have
equal rights to voting, redemptions, dividends and liquidation, except that
certain expenses, subject to the approval of the Trustees, may be applied
differently to each class of shares in accordance with current regulations of
the Securities and Exchange Commission and the Internal Revenue Service.
Shareholders of a class which bears distribution and service expenses under
terms of a distribution plan have exclusive voting rights to that distribution
plan.

      Significant accounting policies of the Fund are as follows:

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

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

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

FEDERAL INCOME TAXES The Fund's policy is to comply with the requirements of the
Internal Revenue Code that are applicable to regulated investment companies and
to distribute all of its taxable income, including any net realized gain on
investments, to its shareholders. Therefore, no federal income tax provision is
required. For federal income tax purposes, the Fund has $18,749,417 of capital
loss carryforwards available, to the extent provided by regulations, to offset
future net realized capital gains. To the extent such carryforwards are used by
the Fund, no capital gains distribution will be made. The carryforwards expire
as follows: May 31, 2002 -- $13,280,667, May 31, 2004 -- $1,419,401, May 31,
2005 -- $1,964,217 and May 31, 2006 -- $2,085,132. Expired capital loss
carryforwards are reclassified to capital paid-in in the year of expiration.

DIVIDENDS, INTEREST AND DISTRIBUTIONS Interest income on investment securities
is recorded on the accrual basis. Foreign income may be subject to foreign
withholding taxes, which are accrued as applicable.

      The Fund records all distributions to shareholders from net investment
income and realized gains on the ex-dividend date. Such distributions are
determined in conformity with income tax regulations, which may differ from
generally accepted accounting principles. Dividends paid by the Fund, if any,
with respect to each class of shares will be calculated in the same manner, at
the same time and will be in the same amount, except for the effect of expenses
that may be applied differently to each class.

USE OF ESTIMATES The preparation of these financial statements in accordance
with generally accepted accounting principles incorporates


                                       15
<PAGE>

==========================NOTES TO FINANCIAL STATEMENTS=========================

                   John Hancock Funds - Government Income Fund

estimates made by management in determining the reported amounts of assets,
liabilities, revenues and expenses of the Fund. Actual results could differ from
these estimates.

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

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

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

BANK BORROWINGS The Fund is permitted to have bank borrowings for temporary or
emergency purposes, including the meeting of redemption requests that otherwise
might require the untimely disposition of securities. These agreements enable
the Fund to participate with other funds managed by the Adviser in unsecured
lines of credit with banks which permit borrowings up to $800 million,
collectively. Interest is charged to each fund, based on its borrowing, at a
rate equal to 0.50% over the Fed Funds Rate. In addition, a commitment fee, at
rates ranging from 0.070% to 0.075% per annum based on the average daily unused
portion of the line of credit, is allocated among the participating funds. The
Fund had no borrowing activity for the year ended May 31, 1998.

FINANCIAL FUTURES CONTRACTS The Fund may buy and sell financial futures
contracts to hedge against the effects of fluctuations in interest rates and
other market conditions. Buying futures tends to increase the Fund's exposure to
the underlying instrument. Selling futures tends to decrease the Fund's exposure
to the underlying instrument or hedge other Fund instruments. At the time the
Fund enters into a financial futures contract, it is required to deposit with
its custodian a specified amount of cash or U.S. government securities, known as
"initial margin," equal to a certain percentage of the value of the financial
futures contract being traded. Each day, the futures contract is valued at the
official settlement price of the board of trade or U.S. commodities exchange on
which it trades. Subsequent payments, known as "variation margin," to and from
the broker are made on a daily basis as the market price of the financial
futures contract fluctuates. Daily variation margin adjustments, arising from
this "mark to market," are recorded by the Fund as unrealized gains or losses.

      When the contracts are closed, the Fund recognizes a gain or loss. Risks
of entering into futures contracts include the possibility that there may be an
illiquid market and/or that a change in the value of the contracts may not
correlate with changes in the value of the underlying securities. In addition,
the Fund could be prevented from opening or realizing the benefits of closing
out futures positions because of position limits or limits on daily price
fluctuation imposed by an exchange.

      For federal income tax purposes, the amount, character and timing of the
Fund's gains and/or losses can be affected as a result of futures contracts.

      At May 31, 1998, open positions in financial futures contracts were as
follows:

                                                        UNREALIZED

                                                       ============

      At May 31, 1998, the Fund had deposited in a segregated account $9,263,455
par value of U.S. Treasury Bond, 8.125%, 08-15-19 to cover margin requirements
on open financial futures contracts.

OPTIONS Listed options will be valued at the last quoted sales price on the
exchange on which they are primarily traded. Purchased put or call
over-the-counter options will be valued at the average of the "bid" prices
obtained from two independent brokers. Written put or call over-the-counter
options will be valued at the average of the "asked" prices obtained from two
independent brokers. Upon the writing of a call or put option, an amount equal
to the premium received by the Fund will


                                       16
<PAGE>

==========================NOTES TO FINANCIAL STATEMENTS=========================

                   John Hancock Funds - Government Income Fund

be included in the Statement of Assets and Liabilities as an asset and
corresponding liability. The amount of the liability will be subsequently marked
to market to reflect the current market value of the written option.

      The Fund may use option contracts to manage its exposure to the bond
market. Writing puts and buying calls will tend to increase the Fund's exposure
to the underlying instrument and buying puts and writing calls will tend to
decrease the Fund's exposure to the underlying instrument, or hedge other Fund
investments.

      The maximum exposure to loss for any purchased options will be limited to
the premium initially paid for the option. In all other cases, the face (or
"notional") amount of each contract at value will reflect the maximum exposure
of the Fund in these contracts, but the actual exposure will be limited to the
change in value of the contract over the period the contract remains open.

      Risks may also arise if counterparties do not perform under the contract's
terms ("credit risk"), or if the Fund is unable to offset a contract with a
counterparty on a timely basis ("liquidity risk"). Exchange-traded options have
minimal credit risk as the exchanges act as counterparties to each transaction,
and only present liquidity risk in highly unusual market conditions. To minimize
credit and liquidity risks in over-the-counter option contracts, the Fund will
continuously monitor the creditworthiness of all its counterparties.

      At any particular time, except for purchased options, market or credit
risk may involve amounts in excess of those reflected in the Fund's period-end
Statement of Assets and Liabilities.

      There were no written option transactions for the year ended May 31, 1998.

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

Under the present investment management contract, the Fund pays a monthly
management fee to the Adviser for a continuous investment program equivalent, on
an annual basis, to the sum of (a) 0.65% of the first $200,000,000 of the Fund's
average daily net asset value, (b) 0.625% of the next $300,000,000 and (c) 0.60%
of the Fund's average daily net asset value in excess of $500,000,000.

      The Fund has a distribution agreement with John Hancock Funds, Inc. ("JH
Funds"), a wholly owned subsidiary of the Adviser. For the year ended May 31,
1998, net sales charges received with regard to sales of Class A shares amounted
to $176,340. Out of this amount, $20,547 was retained and used for printing
prospectuses, advertising, sales literature and other purposes, $141,990 was
paid as sales commissions to unrelated broker-dealers and $13,803 was paid as
sales commissions to sales personnel of John Hancock Distributors, Inc.
("Distributors"), a related broker-dealer. The Adviser's indirect parent, John
Hancock Mutual Life Insurance Company ("JHMLICo"), is the indirect sole
shareholder of Distributors.

      Class B shares which are redeemed within six years of purchase will be
subject to a contingent deferred sales charge ("CDSC") at declining rates
beginning at 5.0% of the lesser of the current market value at the time of
redemption or the original purchase cost of the shares being redeemed. Proceeds
from the CDSC are paid to JH Funds and are used in whole or in part to defray
its expenses related to providing distribution related services to the Fund in
connection with the sale of Class B shares. For the year ended May 31, 1998,
contingent deferred sales charges paid to JH Funds amounted to $272,098.

      In addition, to reimburse JH Funds for the services it provides as
distributor of shares of the Fund, the Fund has adopted a Distribution Plan with
respect to Class A and Class B pursuant to Rule 12b-1 under the Investment
Company Act of 1940. Accordingly, the Fund will make payments to JH Funds for
distribution and service expenses, at an annual rate not to exceed 0.25% of
Class A average daily net assets and 1.00% of Class B average daily net assets
to reimburse JH Funds for its distribution and service costs. Up to a maximum of
0.25% of such payments may be service fees as defined by the amended Rules of
Fair Practice of the National Association of Securities Dealers. Under the
amended Rules of Fair Practice, curtailment of a portion of the Fund's 12b-1
payments could occur under certain circumstances.

      The Fund has a transfer agent agreement with John Hancock Signature
Services, Inc. ("Signature Services"), an indirect subsidiary of

JHMLICo. The Fund pays transfer agent fees based on the number of shareholder
accounts and certain out-of-pocket expenses.

      The Fund has an agreement with the Adviser to perform necessary tax and
financial management services for the Fund. The compensation for the period was
at an annual rate of less than 0.02% of the average net assets of the Fund.

      Mr. Edward J. Boudreau, Jr., Ms. Anne C. Hodsdon and Mr. Richard S.
Scipione are directors and/or officers of the Adviser and/or its affiliates, as
well as Trustees of the Fund. The compensation of unaffiliated Trustees is borne
by the Fund. The unaffiliated Trustees may elect to defer for tax purposes their
receipt of this compensation under the John Hancock Group of Funds Deferred
Compensation Plan. The Fund makes investments into other John Hancock funds, as
applicable, to cover its liability for the deferred compensation. Investments to
cover the Fund's deferred compensation liability are recorded on the Fund's
books as an other asset. The deferred compensation liability and the related
other asset are always equal and are marked to market on a periodic basis to
reflect any income earned by the investment as well as any unrealized gains or
losses. At May 31, 1998, the Fund's investments to cover the deferred
compensation liability had unrealized appreciation of $7,588.

NOTE C -
INVESTMENT TRANSACTIONS

Purchases and proceeds from sales of securities, other than short-term
obligations, during the year ended May 31, 1998, aggregated $506,426,797 and
$582,636,390, respectively.

      The cost of investments (including the joint repurchase agreement) owned
at May 31, 1998 for federal income tax purposes was $440,840,282. Gross
unrealized appreciation and depreciation of investments aggregated $16,013,103
and $6,460,743, respectively, resulting in net unrealized appreciation of
$9,552,360.

NOTE D -
RECLASSIFICATION OF CAPITAL ACCOUNTS

During the year ended May 31, 1998, the Fund has reclassified amounts to reflect
a decrease in accumulated net realized loss on investments of $4,273, a decrease
in distributions in excess of net investment income of $866, and a decrease in
capital paid-in of $5,139. This represents the amount necessary to report these
balances on a tax basis, excluding certain temporary differences, as of May 31,
1998. Additional adjustments may be needed in subsequent reporting periods.
These reclassifications, which have no impact on the net asset value of the
Fund, are primarily attributable to certain differences in the computation of
distributable income and capital gains under federal tax rules versus generally
accepted accounting principles.

                   John Hancock Funds - Government Income Fund

REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS 
To the Board of Trustees and Shareholders of 
John Hancock Bond Trust

We have audited the accompanying statement of assets and liabilities of the John
Hancock Government Income Fund (one of the portfolios constituting the John
Hancock Bond Trust) (the "Fund"), including the schedule of investments, as of
May 31, 1998, and the related statement of operations for the year then ended,
and the statement of changes in net assets and the financial highlights for each
of the periods indicated therein. These financial statements and financial
highlights are the responsibility of the Fund's management. Our responsibility
is to express an opinion on these financial statements and financial highlights
based on our audits.

      We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements and financial
highlights are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. Our procedures included confirmation of securities owned as of May
31, 1998, by correspondence with the custodian and brokers, or other appropriate
auditing procedures where replies from brokers were not received. An audit also
includes assessing the accounting principles used and significant estimates made
by management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our
opinion.

      In our opinion, the financial statements and financial highlights referred
to above present fairly, in all material respects, the financial position of the
John Hancock Government Income Fund of the John Hancock Bond Trust at May 31,
1998, the results of its operations for the year then ended, the changes in its
net assets and the financial highlights for each of the indicated periods, in
conformity with generally accepted accounting principles.

ORGANIZATION OF THE FUNDS

The Funds are series of the Trust, an open-end investment management company
organized as a Massachusetts business trust under the laws of The Commonwealth
of Massachusetts. Prior to December 22, 1994, the Government Income Fund was
called Transamerica Government Income Fund and the High Yield Bond Fund was
called Transamerica High Yield Bond Fund. Prior to August 30, 1996, the Funds
were series of John Hancock Series, Inc., a Maryland corporation.

John Hancock Advisers, Inc. (the "Adviser") is the Funds' investment adviser.
The Adviser is an indirect wholly-owned subsidiary of John Hancock Mutual Life
Insurance Company (the "Life Company"), a Massachusetts life insurance company
chartered in 1862 ,with national headquarters at John Hancock Place, Boston,
Massachusetts.

INVESTMENT OBJECTIVES AND POLICIES

The following information supplements the discussion of the Funds' investment
objectives and policies discussed in the Prospectus. There is no assurance that
either Fund will achieve its investment objective.

                             Government Income Fund

The Government Income Fund's investment objective is to earn a high level of
current income consistent with preservation of capital by investing primarily in
securities that are issued or guaranteed as to principal and interest by the
U.S. Government, its agencies or instrumentalities. The Fund may seek to enhance
its current return and may seek to hedge against changes in interest rates by
engaging in transactions involving options (subject to certain limits), futures
and options on futures.

The Fund expects that under normal market conditions, it will invest a least 80%
of its total assets in U.S. Government securities (and related repurchase
agreements and forward commitments) which include:

      1. Obligations issued by the U.S. Treasury differing only in their
interest rates, maturities and times of issuance:

      (a)   U.S. Treasury bills with a maturity of one year or less;

      (b)   U.S. Treasury notes with maturities of one to ten years; or

      (c)   U.S. Treasury bonds generally with maturities greater than ten
            years; and

      2. Obligations issued or guaranteed by the U.S. Government, its agencies
or instrumentalities which may be supported by:

      (a)   the full faith and credit of the U.S. Government (e.g., direct
            pass-through certificates of the Government National Mortgage
            Association ("Ginnie Mae"));

      (b)   the right of the issuer to borrow from the U.S. Government (e.g.,
            securities of the Federal Home Loan banks); or

      (c)   the credit of the instrumentality (e.g., bonds issued by Federal
            National Mortgage Association.)


                                       2
<PAGE>

The Adviser will attempt to minimize excessive fluctuations in net asset value
per share, so at times the highest yielding government securities then available
may not be selected for investment if, in the view of the Adviser, future
interest rate movements could result in depreciation of value of such
securities. The Fund may take full advantage of the entire range of maturities
of U.S. Government securities and may adjust the dollar-weighted average
maturity of its portfolio from time to time based in large part on the Adviser's
expectation as to future changes in interest rates.

As to the balance of the Fund's assets, where consistent with the investment
objective, the Fund may:

      1. invest in U.S. dollar denominated securities issued or guaranteed by
foreign governments which are considered stable by the Adviser, or any of the
political subdivisions, instrumentalities, authorities or agencies of these
governments. These securities generally will be rated within the four highest
rating categories by a nationally recognized rating organization (e.g. Standard
& Poor's Rating Group ("S&P") or Moody's Investors Service, Inc. ("Moody's")) or
if not so rated, determined to be of equivalent quality in the opinion of the
Adviser; provided that the Fund may invest up to 10% of its total assets in
securities which may be rated B or better by a nationally recognized rating
organization.

      2. invest in other "asset backed securities" which are not included as
"government asset backed": securities and are rated in one of the two highest
rating categories by a nationally recognized credit rating organization or if
not so rated, determined to be of equivalent investment quality in the opinion
the Adviser;

      3. engage in hedging transactions, including options, interest rate
futures contracts and options thereon, subject to certain limitations described
below;

      4. enter into repurchase agreements and reverse repurchase agreements and
invest in when issued securities and restricted securities, subject to certain
limitations described below;

      5. invest in (for liquidity purposes) high quality, short-term debt
securities with remaining maturities of one year or less ("money market
instruments") such as certificates of deposit, bankers' acceptances, corporate
debt securities, commercial paper and related repurchase agreements.

                              High Yield Bond Fund

The High Yield Bond Fund's primary investment objective is to maximize current
income without assuming undue risk by investing in a diversified portfolio
consisting primarily of lower-rated, high yielding, fixed income securities,
such as: domestic and foreign corporate bonds; debentures and notes; convertible
securities; preferred stocks; and domestic and foreign government obligations.
As a secondary objective, the Fund seeks capital appreciation, but only when it
is consistent with the primary objective of maximizing current income. The
Fund's investment objectives may not be changed without 30 days' prior written
notice to shareholders.

Under normal market conditions, at least 65% of the Fund's total assets may be
invested in bonds or debentures rated "Baa" or lower by Moody's, or "BBB" or
lower by S&P; however, no more than 30% of the Fund's total assets may be
invested in securities that are rated as low as "CC" by S&P or "Ca" by Moody's.
Unrated securities will also be considered for investment by the Fund when the
Adviser believes that the issuer's financial condition, or the protection
afforded by the


                                       3
<PAGE>

terms of the securities themselves, limits the risk to the Fund to a degree
comparable to that of rated securities consistent with the Fund's objectives and
policies.

The Fund's investments in debt securities may include zero coupon bonds and
payment-in-kind bonds. Zero coupon bonds are issued at a significant discount
from their principal amount in lieu of paying interest periodically.
Payment-in-kind bonds allow the issuer, at its option, to make current interest
payments on the bonds either in cash or in additional bonds. The market prices
of zero coupon and payment-in-kind bonds are affected to a greater extent by
interest rate changes, and thereby tend to be more volatile than securities
which pay interest periodically and in cash. The Fund accrues income on these
securities for tax and accounting purposes, and this income is required to be
distributed to shareholders. Because no cash is received at the time income
accrues on these securities, the Fund may be forced to liquidate other
investments to make distributions. At times when the Fund invests in zero-coupon
and payment-in-kind bonds, it will not be pursuing its primary objective of
maximizing current income.

Although the Fund intends to maintain investment emphasis on debt securities of
domestic issuers, the Fund may invest without limitation in debt securities of
foreign issuers, including those issued by supranational entities such as the
World Bank. The Fund may also purchase debt securities issued in an any country
developed or undeveloped. Investments in securities of issuers in
non-industrialized countries generally involve more risk and may be considered
speculative. The Fund may also enter into forward foreign currency exchange
contracts for the purchase or sale of foreign currency for hedging purposes. The
risks of foreign investments should be carefully considered by investors.

Included among domestic debt securities eligible for purchase by the Fund are
adjustable and variable or floating rate securities, mortgage related securities
(including stripped securities, collateralized mortgage obligations and
multi-class pass-through securities), asset-backed securities and callable
bonds. Callable bonds have a provision permitting the issuer, at its option to
"call" or redeem the bonds. If an issuer were to redeem bonds held by the Fund
during a time of declining interest rates, the Fund might not be able to
reinvest the proceeds in bonds providing the same coupon return as the bonds
redeemed.

To the extent that the Fund does not invest in the securities described above,
the Fund may:

      1. invest (for liquidity purposes ) in high quality, short-term debt
securities with remaining maturities of one year or less ("money market
instruments") including government obligations, certificates of deposit,
bankers' acceptances, short-term corporate debt securities, commercial paper and
related repurchase agreements;

      2. invest up to 10% of its total assets in municipal obligations,
including municipal bonds issued at a discount, in circumstances where the
Adviser determines that investing in such obligations would facilitate the
Fund's ability to accomplish its investment objectives;

      3. lend its portfolio securities, enter into repurchase agreements and
reverse repurchase agreements, purchase restricted and illiquid securities and
purchase securities on a when issued or forward commitment basis;

      4. write (sell) covered call and put options and purchase call and put
options on debt securities and securities indices in an effort to increase
current income and for hedging purposes; and


                                       4
<PAGE>

      5. purchase and sell interest rate futures contracts on debt securities
and securities index futures contracts, and write and purchase options on these
futures contracts for hedging purposes.

During periods of unusual market conditions when the Adviser believes that
investing for temporary defensive purposes is appropriate, part or all of the
assets of the Fund may be invested in cash or cash equivalents consisting of:

      1. obligations of banks (including certificates of deposit, bankers'
acceptances and repurchase agreements ) with assets of $100,000,0000 or more;

      2. commercial paper rated within the two highest rating categories of a
nationally recognized rating organization;

      3. investment grade short-term notes;

      4. obligations issued or guaranteed by the U.S. Government or any of its
agencies or instrumentalities; and

      5. related repurchase agreements.

Government Securities. Each Fund may invest in U.S. Government securities, which
are obligations issued or guaranteed by the U.S. Government and its agencies,
authorities or instrumentalities. Certain U.S. Government securities, including
U.S. Treasury bills, notes and bonds, and Government National Mortgage
Association certificates ("Ginnie Maes"), are supported by the full faith and
credit of the United States. Certain other U.S. Government securities, issued or
guaranteed by Federal agencies or government sponsored enterprises, are not
supported by the full faith and credit of the United States, but may be
supported by the right of the issuer to borrow from the U.S. Treasury. These
securities include obligations of the Federal Home Loan Mortgage Corporation
("Freddie Macs"), and obligations supported by the credit of the
instrumentality, such as Federal National Mortgage Association Bonds ("Fannie
Maes").

Custodial Receipts. The Funds may acquire custodial receipts for U.S. government
securities. Custodial receipts evidence ownership of future interest payments,
principal payments or both, and include Treasury Receipts, Treasury Investors
Growth Receipts ("TIGRs"), and Certificates of Accrual on Treasury Securities
("CATS"). Custodial receipts are not considered U.S.
government securities.

Bank and Corporate Obligations. Each of the Funds may invest in commercial
paper. Commercial paper represents short-term unsecured promissory notes issued
in bearer form by banks or bank holding companies, corporations and finance
companies. The commercial paper purchased by the Funds consists of direct U.S.
dollar denominated obligations of domestic or foreign issuers. Bank obligations
in which a Fund may invest include certificates of deposit, bankers' acceptances
and fixed time deposits. Certificates of deposit are negotiable certificates
issued against funds deposited in a commercial bank for a definite period of
time and earning a specified return.

Bankers' acceptances are negotiable drafts or bills of exchange, normally drawn
by an importer or exporter to pay for specific merchandise, which are "accepted"
by a bank, meaning, in effect, that the bank unconditionally agrees to pay the
face value of the instrument on maturity. Fixed time deposits are bank
obligations payable at a stated maturity date and bearing interest at a fixed
rate.


                                       5
<PAGE>

Fixed time deposits may be withdrawn on demand by the investor, but may be
subject to early withdrawal penalties which vary depending upon market
conditions and the remaining maturity of the obligation. There are no
contractual restrictions on the right to transfer a beneficial interest in a
fixed time deposit to a third party, although there is no market for such
deposits. Bank notes and bankers' acceptances rank junior to domestic deposit
liabilities of the bank and pari passu with other senior, unsecured obligations
of the bank. Bank notes are not insured by the Federal Deposit Insurance
Corporation or any other insurer. Deposit notes are insured by the Federal
Deposit Insurance Corporation only to the extent of $100,000 per depositor per
bank.

Municipal Obligations. High Yield Bond Fund may invest in a variety of municipal
obligations which consist of municipal bonds, municipal notes and municipal
commercial paper.

Municipal Bonds. Municipal bonds are issued to obtain funds for various public
purposes including the construction of a wide range of public facilities such as
airports, highways, bridges, schools, hospitals, housing, mass transportation,
streets and water and sewer works. Other public purposes for which municipal
bonds may be issued include refunding outstanding obligations, obtaining funds
for general operating expenses and obtaining funds to lend to other public
institutions and facilities. In addition, certain types of industrial
development bonds are issued by or on behalf of public authorities to obtain
funds for many types of local, privately operated facilities. Such debt
instruments are considered municipal obligations if the interest paid on them is
exempt from federal income tax. The payment of principal and interest by issuers
of certain obligations purchased by the Fund may be guaranteed by a letter of
credit, note repurchase agreement, insurance or other credit facility agreement
offered by a bank or other financial institution. Such guarantees and the
creditworthiness of guarantors will be considered by the Adviser in determining
whether a municipal obligation meets the Fund's investment quality requirements.
No assurance can be given that a municipality or guarantor will be able to
satisfy the payment of principal or interest on a municipal obligation.

Municipal Notes. Municipal notes are short-term obligations of municipalities,
generally with a maturity ranging from six months to three years. The principal
types of such notes include tax, bond and revenue anticipation notes and project
notes.

Municipal Commercial Paper. Municipal commercial paper is a short-term
obligation of a municipality, generally issued at a discount with a maturity of
less than one year. Such paper is likely to be issued to meet seasonal working
capital needs of a municipality or interim construction financing. Municipal
commercial paper is backed in many cases by letters of credit, lending
agreements, note repurchase agreements or other credit facility agreements
offered by banks and other institutions.

Federal tax legislation enacted in the 1980s placed substantial new restrictions
on the issuance of the bonds described above and in some cases eliminated the
ability of state or local governments to issue municipal obligations for some of
the above purposes. Such restrictions do not affect the Federal income tax
treatment of municipal obligations in which the Fund may invest which were
issued prior to the effective dates of the provisions imposing such
restrictions. The effect of these restrictions may be to reduce the volume of
newly issued municipal obligations.

Issuers of municipal obligations are subject to the provisions of bankruptcy,
insolvency and other laws affecting the rights and remedies of creditors, such
as the Federal Bankruptcy Act, and laws, if any, which may be enacted by
Congress or state legislatures extending the time for payment of principal or
interest, or both, or imposing other constraints upon enforcement of such
obligations.


                                       6
<PAGE>

There is also the possibility that as a result of litigation or other conditions
the power or ability of any one or more issuers to pay when due the principal of
and interest on their municipal obligations may be affected.

The yields of municipal bonds depend upon, among other things, general money
market conditions, general conditions of the municipal bond market, size of a
particular offering, the maturity of the obligation and rating of the issue. The
ratings of S&P, Moody's and Fitch Investors Service ("Fitch") represent their
respective opinions on the quality of the municipal bonds they undertake to
rate. It should be emphasized, however, that ratings are general and not
absolute standards of quality. Consequently, municipal bonds with the same
maturity, coupon and rating may have different yields and municipal bonds of the
same maturity and coupon with different ratings may have the same yield. See the
Appendix for a description of ratings. Many issuers of securities choose not to
have their obligations rated. Although unrated securities eligible for purchase
by the Fund must be determined to be comparable in quality to securities having
certain specified ratings, the market for unrated securities may not be as broad
as for rated securities since many investors rely on rating organizations for
credit appraisal.

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

Guaranteed Mortgage Pass-Through Securities. Guaranteed mortgage pass-through
securities represent participation interests in pools of residential mortgage
loans and are issued by U.S. Governmental or private lenders and guaranteed by
the U.S. Government or one of its agencies or instrumentalities, including but
not limited to Ginnie Mae, Fannie Mae and Freddie Macs.

Multiple-Class Pass-Through Securities and Collateralized Mortgage Obligations.
CMOs and REMIC pass-through or participation certificates may be issued by,
among others, U.S. Government agencies and instrumentalities as well as private
lenders. CMOs and REMIC certificates are issued in multiple classes and the
principal of and interest on the mortgage assets may be allocated among the
several classes of CMOs or REMIC certificates in various ways. Each class of
CMOs or REMIC certificates, often referred to as a "tranche," is issued at a
specific adjustable or fixed interest rate and must be fully retired no later
than its final distribution date. Generally, interest is paid or accrues on all
classes of CMOs or REMIC certificates on a monthly basis.

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

A REMIC is a CMO that qualifies for special tax treatment under the Internal
Revenue Code of 1986, as amended (the "Code"), and invests in certain mortgages
primarily secured by interests in real property and other permitted investments.
Investors may purchase "regular" or "residual" interests in REMICs, although the
Funds do not intend, absent a change in current tax law, to invest in residual
interests.

Stripped Mortgage-Backed Securities. SMBS are derivative multiple-class
mortgage-backed securities. SMBS are usually structured with two classes that
receive different proportions of interest and principal distributions on a pool
of mortgage assets. A typical SMBS will have one


                                       7
<PAGE>

class receiving some of the interest and most of the principal, while the other
class will receive most of the interest and the remaining principal. In the most
extreme case, one class will receive all of the interest (the "interest only"
class) while the other class will receive all of the principal (the "principal
only" class). The yields and market risk of interest only and principal only
SMBS, respectively, may be more volatile than those of other fixed income
securities. The staff of the SEC considers privately issued SMBS to be illiquid.

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

Participation Interests. Participation interests, which may take the form of
interests in, or assignments of certain loans, are acquired from banks who have
made these loans or are members of a lending syndicate. The Fund's investments
in participation interests may be subject to its 10% limitation on investments
in illiquid securities.

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

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

Conversely, in a rising interest rate environment, a declining prepayment rate
will extend the average life of many Mortgage-Backed Securities. This
possibility is often referred to as extension


                                       8
<PAGE>

risk. Extending the average life of a Mortgage-Backed Security increases the
risk of depreciation due to future increases in market interest rates.

Risk Associated with Mortgage-backed Securities. Different types of derivative
debt securities are subject to different combinations of prepayment, extension
and/or interest rate risk. Conventional mortgage pass-through securities and
sequential pay CMOs are subject to all of these risks, but are typically not
leveraged. Thus, the magnitude of exposure may be less than for more leveraged
Mortgage-Backed Securities.

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

These securities include floating rate securities based on the Cost of Funds
Index ("COFI floaters"), other "lagging rate" floating rate securities, floating
rate securities that are subject to a maximum interest rate ("capped floaters"),
Mortgage-Backed Securities purchased at a discount, leveraged inverse floating
rate securities ("inverse floaters"), principal only debt securities ("POs"),
certain residual or support tranches of CMOs and index amortizing notes. Index
amortizing notes are not Mortgage-Backed Securities, but are subject to
extension risk resulting from the issuer's failure to exercise its option to
call or redeem the notes before their stated maturity date. Leveraged inverse
IOs combine several elements of the Mortgage-Backed Securities described above
and thus present an especially intense combination of prepayment, extension and
interest rate risks.

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

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

Convertible Securities. High Yield Bond Fund may invest in convertible
securities. Convertible securities may be converted at either a stated price or
stated rate into underlying shares of common stock of the same issuer.
Convertible securities have general characteristics similar to both fixed income
and equity securities. The market value of convertible securities declines as
interest rates increase, and increases as interest rates decline. In addition,
because of the conversion feature, the market value of convertible securities
tends to vary with fluctuations in the market value of the underlying common
stocks and therefore will also react to variations in the general market for
equity securities. A unique feature of convertible securities is that as the
market price of the underlying common stock declines, convertible securities
tend to trade increasingly on a yield basis,


                                       9
<PAGE>

and consequently may not experience market value declines to the same extent as
the underlying common stock. When the market price of the underlying common
stock increases, the prices of the convertible securities tend to rise as a
reflection of the value of the underlying common stock. While no securities
investments are without risk, investments in convertible securities generally
entail less risk than investments in common stock of the same issuer. However,
the issuers of convertible securities may default on their obligations.

Mortgage "Dollar Roll" Transactions. The Funds may enter into mortgage "dollar
roll" transactions with selected banks and broker-dealers pursuant to which a
Fund sells Mortgage-Backed Securities and simultaneously contracts to repurchase
substantially similar (same type, coupon and maturity) securities on a specified
future date. The Funds will only enter into covered rolls. A "covered roll" is a
specific type of dollar roll for which there is an offsetting cash position or a
cash equivalent security position which matures on or before the forward
settlement date of the dollar roll transaction. Covered rolls are not treated as
a borrowing or other senior security and will be excluded from the calculation
of a Fund's borrowing and other senior securities. For financial reporting and
tax purposes, each Fund treats mortgage dollar rolls as two separate
transactions; one involving the purchase of a security and a separate
transaction involving a sale. Neither Fund currently intends to enter into
mortgage rolls that are accounted for as financing.

Pay-In-Kind, Delayed and Zero Coupon Bonds. Each Fund may invest in pay-in-kind,
delayed and zero coupon bonds. These are securities issued at a discount from
their face value because interest payments are typically postponed until
maturity. The amount of the discount rate varies depending on factors including
the time remaining until maturity, prevailing interest rates, the security's
liquidity and the issuer's credit quality. These securities also may take the
form of debt securities that have been stripped of their interest payments. A
portion of the discount with respect to stripped tax-exempt securities or their
coupons may be taxable. The market prices of pay-in-kind, delayed and zero
coupon bonds generally are more volatile than the market prices of
interest-bearing securities and are likely to respond to a greater degree to
changes in interest rates than interest-bearing securities having similar
maturities and credit quality. A Fund's investments in pay-in-kind, delayed and
zero coupon bonds may require the Fund to sell certain of its portfolio
securities to generate sufficient cash to satisfy certain income distribution
requirements. See "Tax Status." At times when a Fund invests in pay-in-kind,
delayed and zero coupon bonds, it will not be pursuing its primary objective of
maximizing current income.

Indexed Securities. High Yield Bond Fund may invest in indexed securities,
including floating rate securities that are subject to a maximum interest rate
("capped floaters") and leveraged inverse floating rate securities ("inverse
floaters") (up to 10% of the Fund's total assets). The interest rate or, in some
cases, the principal payable at the maturity of an indexed security may change
positively or inversely in relation to one or more interest rates, financial
indices or other financial indicators ("reference prices"). An indexed security
may be leveraged to the extent that the magnitude of any change in the interest
rate or principal payable on an indexed security is a multiple of the change in
the reference price. Thus, indexed securities may decline in value due to
adverse market changes in interest rates or other reference prices.

Swaps, Caps, Floors and Collars. As one way of managing its exposure to
different types of investments, each Fund may enter into interest rate swaps and
other types of swap agreements such as caps, collars and floors. Only High Yield
Bond Fund may enter into currency swaps, caps, collars and floors. In a typical
interest rate swap, one party agrees to make regular payments equal to a
floating interest rate times a "notional principal amount," in return for
payments equal to a fixed rate times the same amount, for a specified period of
time. If a swap agreement provides for


                                       10
<PAGE>

payment in different currencies, the parties might agree to exchange the
notional principal amount as well. Swaps may also depend on other prices or
rates, such as the value of an index or mortgage prepayment rates.

In a typical cap or floor agreement, one party agrees to make payments only
under specified circumstances, usually in return for payment of a fee by the
other party. For example, the buyer of an interest rate cap obtains the right to
receive payments to the extent that a specified interest rate exceeds an
agreed-upon level, while the seller of an interest rate floor is obligated to
make payment to the extent that a specified interest rate falls below an
agreed-upon level. An interest rate collar combines elements of buying a cap and
selling a floor.

Swap agreements will tend to shift a Fund's investment exposure from one type of
investment to another. For example, if a Fund agreed to exchange payments in
dollars for payments in a foreign currency, the swap agreement would tend to
decrease the Fund's exposure to U.S. interest rates and increase its exposure to
foreign currency and interest rates. Caps and floors have an effect similar to
buying or writing options. Depending on how they are used, swap agreements may
increase or decrease the overall volatility of a Fund's investments and its
share price and yield.

Swap agreements are sophisticated hedging instruments that typically involve a
small investment of cash relative to the magnitude of risks assumed. As a
result, swaps can be highly volatile and may have a considerable impact on a
Fund's performance. Swap agreements are subject to risks related to the
counterparty's ability to perform, and may decline in value if the
counterparty's creditworthiness deteriorates. A Fund may also suffer losses if
it is unable to terminate outstanding swap agreements or reduce its exposure
through offsetting transactions. Each Fund will maintain in a segregated account
with its custodian, cash or liquid securities equal to the net amount, if any,
of the excess of the Fund's obligations over its entitlements with respect to
swap, cap, collar or floor transactions.

Asset-Backed Securities. Government Income Fund and High Yield Bond Fund may
invest a portion of their assets in asset-backed securities. Asset backed
securities, like Ginnie Mae certificates, are securities which represent a
participation in or are secured by and payable from, a stream of payments
generated by particular assets, most often a pool of assets similar to one
another. Types of other asset backed securities include automobile receivable
securities, credit card receivable securities and mortgage backed securities
such as collateralized mortgage obligations ("CMOs") and real estate mortgage
investment conduits ("REMICs").

Asset-backed securities are often subject to more rapid repayment than their
stated maturity date would indicate as a result of the pass-through of
prepayments of principal on the underlying loans. During periods of declining
interest rates, prepayment of loans underlying asset-backed securities can be
expected to accelerate. Accordingly, a Fund's ability to maintain positions in
such securities will be affected by reductions in the principal amount of such
securities resulting from prepayments, and its ability to reinvest the returns
of principal at comparable yields is subject to generally prevailing interest
rates at that time.

Credit card receivables are generally unsecured and the debtors on such
receivables are entitled to the protection of a number of state and federal
consumer credit laws, many of which give such debtors the right to set-off
certain amounts owed on the credit cards, thereby reducing the balance due.
Automobile receivables generally are secured, but by automobiles rather than
residential real property. Most issuers of automobile receivables permit the
loan servicers to retain possession of the underlying obligations. If the
servicer were to sell these obligations to another party, there is a


                                       11
<PAGE>

risk that the purchaser would acquire an interest superior to that of the
holders of the asset-backed securities. In addition, because of the large number
of vehicles involved in a typical issuance and technical requirements under
state laws, the trustee for the holders of the automobile receivables may not
have a proper security interest in the underlying automobiles. Therefore, there
is the possibility that, in some cases, recoveries on repossessed collateral may
not be available to support payments on these securities.

Lower Rated High Yield Debt Obligations. Government Income Fund and High Yield
Bond Fund may invest in high yielding, fixed income securities rated below
investment grade (e.g., rated below Baa by Moody's or below BBB by S&P),
sometimes referred to as junk bonds. No more than 10% of Government Income
Fund's total assets may be invested in these securities, and Government Income
Fund may not invest in securities rated lower than B by a nationally recognized
rating organization. Ratings are based largely on the historical financial
condition of the issuer. Consequently, the rating assigned to any particular
security is not necessarily a reflection of the issuer's current financial
condition, which may be better or worse than the rating would indicate.

See the Appendix to this Statement of Additional Information which describes the
characteristics of corporate bonds in the various rating categories. High Yield
Bond Fund may invest in comparable quality unrated securities which, in the
opinion of the Adviser, offer comparable yields and risks to those securities
which are rated.

Debt obligations rated in the lower ratings categories, or which are unrated,
involve greater volatility of price and risk of loss of principal and income. In
addition, lower ratings reflect a greater possibility of an adverse change in
financial condition affecting the ability of the issuer to make payments of
interest and principal. The high yield fixed income market is relatively new and
its growth occurred during a period of economic expansion. The market has not
yet been fully tested by an economic recession.

The market price and liquidity of lower rated fixed income securities generally
respond to short term corporate and market developments to a greater extent than
do the price and liquidity of higher rated securities because such developments
are perceived to have a more direct relationship to the ability of an issuer of
such lower rated securities to meet its ongoing debt obligations.

Reduced volume and liquidity in the high yield bond market or the reduced
availability of market quotations will make it more difficult to dispose of the
bonds and to value accurately a Fund's assets. The reduced availability of
reliable, objective data may increase a Fund's reliance on management's judgment
in valuing high yield bonds. In addition, a Fund's investments in high yield
securities may be susceptible to adverse publicity and investor perceptions,
whether or not justified by fundamental factors. A Fund's investments, and
consequently its net asset value, will be subject to the market fluctuations and
risks inherent in all securities.

Brady Bonds. The Funds may invest in Brady Bonds and other sovereign debt
securities of countries that have restructured or are in the process of
restructuring sovereign debt pursuant to the Brady Plan. Brady Bonds are debt
securities described as part of a restructuring plan created by U.S. Treasury
Secretary Nicholas F. Brady in 1989 as a mechanism for debtor nations to
restructure their outstanding external indebtedness (generally, commercial bank
debt). In restructuring its external debt under the Brady Plan framework, a
debtor nation negotiates with its existing bank lenders as well as multilateral
institutions such as the World Bank and the International Monetary Fund (the
"IMF"). The Brady Plan facilitate the exchange of commercial bank debt for newly
issued debt (known as Brady Bonds). The World Bank and the IMF provide funds
pursuant to loan


                                       12
<PAGE>

agreements or other arrangements which enable the debtor nation to collateralize
the new Brady Bonds or to repurchase outstanding bank debt at a discount. Under
these arrangements IMF debtor nations are required to implement domestic
monetary and fiscal reforms. These reforms have included the liberalization of
trade and foreign investment, the privatization of state-owned enterprises and
the setting of targets for public spending and borrowing. These policies and
programs promote the debtor country's ability to service its external
obligations and promote its economic growth and development. The Brady Plan only
sets forth general guiding principles for economic reform and debt reduction,
emphasizing that solutions must be negotiated on a case-by-case basis between
debtor nations and their creditors. The Adviser believes that economic reforms
undertaken by countries in connection with the issuance of Brady Bonds make the
debt of countries which have issued or have announced plans to issue Brady Bonds
an attractive opportunity for investment.

Brady Bonds have recently been issued by Argentina, Brazil, Bulgaria, Costa
Rica, Dominican Republic, Ecuador, Jordan, Mexico, Nigeria, Poland, the
Philippines, Uruguay and Venezuela and may be issued by other countries. Over
$130 billion in principal amount of Brady Bonds have been issued to date, the
largest portion having been issued by Argentina and Brazil. Brady Bonds may
involve a high degree of risk, may be in default or present the risk of default.
As of January 1, 1997, the Funds are not aware of the occurrence of any payment
defaults on Brady Bonds. Investors should recognize however, that Brady Bonds
have been issued only recently, and, accordingly, they do not have along payment
history. Agreements implemented under the Brady Plan to date are designed to
achieve debt and debt-service reduction through specific options negotiated by a
debtor nation with its creditors. As a result, the financial packages offered by
each country differ. The types of options have included the exchange of
outstanding commercial bank debt for bonds issued at 100% of face value of such
debt, bonds issued at a discount of face value of such debt, bonds bearing an
interest rate which increases over time and bonds issued in exchange for the
advancement of new money by existing lenders. Certain Brady Bonds have been
collateralized as to principal due at maturity by U.S. Treasury zero coupon
bonds with a maturity equal to the final maturity of such Brady Bonds, although
the collateral is not available to investors until the final maturity of the
Brady Bonds. Collateral purchases are financed by the IMF, the World Bank and
the debtor nations' reserves. In addition, the first two or three interest
payments on certain types of Brady Bonds may be collateralized by cash or
securities agreed upon by creditors. Although Brady Bonds may be collateralized
by U.S. Government securities, repayment of principal and interest is not
guaranteed by the U.S. Government.

Ratings as Investment Criteria In general, the ratings of Moody's and S&P
represent the opinions of these agencies as to the quality of the securities
which they rate. It should be emphasized however, that ratings are relative and
subjective and are not absolute standards of quality. These rating will be used
by the Funds as initial criteria for the selection of portfolio securities.
Among the factors which will be considered are the long-term ability of the
issuer to pay principal and interest and general economic trends. Appendix A
contains further information concerning the rating of Moody's and S&P and their
significance. Subsequent to its purchase by the Funds, an issue of securities
may cease to be rated, or its rating may be reduced below the minimum required
for purchase by the Funds. Neither of these events will require the sale of the
securities by the Funds.

Subsequent to its purchase by the Fund, an issue of securities may cease to be
rated or its rating may be reduced below the minimum required for purchase by
the Fund. Neither of these events will require the sale of the securities by the
Fund, but the Adviser will consider the event in its determination of whether
the Fund should continue to hold the securities.


                                       13

Investments in Foreign Securities. Government Income Fund may invest in U.S.
dollar denominated securities of foreign governments. These securities will
generally be rated within the four highest rating categories by a nationally
recognized rating organization S&P or Moody's or if not so rated, determined to
be of equivalent quality in the opinion of the Adviser; provided that Government
Income Fund may invest up to 10% of its total assets in securities which may be
rated B or better by a nationally recognized rating organization.

High Yield Bond Fund may invest in securities of foreign issuers, including debt
and equity securities of corporate and governmental issuers in countries with
emerging economies or securities markets. High Yield Bond Fund may also invest
in American Depository Receipts ("ADRs"), European Depository Receipts ("EDRs")
or other securities convertible into securities of foreign issuers. These
securities may not necessarily be denominated in the same currency as the
securities into which they may be converted but rather in the currency of the
market in which they are traded. ADRs are receipts typically issued by an
American bank or trust company which evidence ownership of underlying securities
issued by a foreign corporation. EDRs are receipts issued in Europe by banks or
depositories which evidence a similar ownership arrangement. Generally, ADRs, in
registered form, are designed for use in U.S. securities markets and EDRs, in
bearer form, are designed for use in European securities markets.

Foreign Currency Transactions. High Yield Bond Fund may engage in foreign
currency transactions. The foreign currency exchange transactions of the Fund
may be conducted on a spot (i.e., cash) basis at the spot rate for purchasing or
selling currency prevailing in the foreign exchange market. The Fund may enter
into forward foreign currency exchange contracts involving currencies of the
different countries in which it may invest as a hedge against possible
variations in the foreign exchange rate between these currencies. Forward
contracts are agreements to purchase or sell a specified currency at a specified
future date and price set at the time of the contract. Transaction hedging is
the purchase or sale of forward foreign currency contracts with respect to
specific receivables or payables of the Fund accruing in connection with the
purchase and sale of its portfolio securities quoted or denominated in the same
or related foreign currencies. Portfolio hedging is the use of forward foreign
currency contracts to offset portfolio security positions denominated or quoted
in the same or related foreign currencies. The Fund's dealings in forward
foreign currency exchange contracts will be limited to hedging either specified
transactions or portfolio positions. The Fund will not attempt to hedge all of
its foreign portfolio positions.

If High Yield Bond Fund enters into a forward contract requiring it to purchase
foreign currency, its custodian bank will segregate cash or liquid securities,
of any type or maturity, in a separate account of the Fund in an amount
necessary to complete the forward contract. These assets will be valued at
market daily and if the value of the securities in the separate account
declines, additional cash or securities will be placed in the account so that
the value of the account will equal the amount of the Fund's commitment in
purchased forward contracts.

Hedging against a decline in the value of currency does not eliminate
fluctuations in the prices of portfolio securities or prevent losses if the
prices of these securities decline. These transactions also preclude the
opportunity for gain if the value of the hedged currency rises. Moreover, it may
not be possible for the Fund to hedge against a devaluation that is so generally
anticipated that the Fund is not able to contract to sell the currency at a
price above the devaluation level it anticipates.

The cost to the Fund of engaging in foreign currency exchange transactions
varies with factors such as the currency involved, the length of the contract
period and the prevailing market conditions.


                                       14
<PAGE>

Since transactions in foreign currency are usually conducted on a principal
basis, no fees or commissions are involved.

Risks of Foreign Securities. Investments in foreign securities may involve a
greater degree of risk than those in domestic securities. There is generally
less publicly available information about foreign companies in the form of
reports and ratings similar to those that are published about issuers in the
United States. Also, foreign issuers are generally not subject to uniform
accounting, auditing and financial reporting requirements comparable to those
applicable to United States issuers.

Because foreign securities may be denominated in currencies other than the U.S.
dollar, changes in foreign currency exchange rates will affect the Fund's net
asset value, the value of dividends and interest earned, gains and losses
realized on the sale of securities, and any net investment income and gains that
the Fund distributes to shareholders. Securities transactions undertaken in some
foreign markets may not be settled promptly, so that the Fund's investments on
foreign exchanges may be less liquid and subject to the risk of fluctuating
currency exchange rates pending settlement.

Foreign securities will be purchased in the best available market, whether
through over-the-counter markets or exchanges located in the countries where
principal offices of the issuers are located. Foreign securities markets are
generally not as developed or efficient as those in the United States. While
growing in volume, they usually have substantially less volume than the New York
Stock Exchange, and securities of some foreign issuers are less liquid and more
volatile than securities of comparable United States issuers. Fixed commissions
on foreign exchanges are generally higher than negotiated commissions on United
States exchanges, although the Fund will endeavor to achieve the most favorable
net results on its portfolio transactions. There is generally less government
supervision and regulation of securities exchanges, brokers and listed issuers
than in the United States.

With respect to certain foreign countries, there is the possibility of adverse
changes in investment or exchange control regulations, expropriation,
nationalization or confiscatory taxation, limitations on the removal of funds or
other assets of the Fund, political or social instability, or diplomatic
developments which could affect United States investments in those countries.
Moreover, individual foreign economies may differ favorably or unfavorably from
the United States economy in terms of growth of gross national product, rate of
inflation, capital reinvestment, resource self-sufficiency and balance of
payments position.

The dividends in some cases, capital gains, and interest payable on certain of
the Fund's foreign portfolio securities may be subject to foreign withholding or
other foreign taxes, thus reducing the net amount of income or gains available
for distribution to the Fund's shareholders.

Repurchase Agreements. Each Fund may invest in repurchase agreements. In a
repurchase agreement the Fund buys a security for a relatively short period
(usually not more than 7 days) subject to the obligation to sell it back to the
issuer at a fixed time and price plus accrued interest. Each Fund will enter
into repurchase agreements only with member banks of the Federal Reserve System
and with "primary dealers" in U.S. Government securities. The Adviser will
continuously monitor the creditworthiness of the parties with whom the Funds
enter into repurchase agreements.

Each Fund has established a procedure providing that the securities serving as
collateral for each repurchase agreement must be delivered to the Fund's
custodian either physically or in book-entry form and that the collateral must
be marked to market daily to ensure that each repurchase agreement is fully
collateralized at all times. In the event of bankruptcy or other default by a
seller


                                       15
<PAGE>

of a repurchase agreement, the Fund could experience delays in liquidating the
underlying securities during the period in which the Fund seeks to enforce its
rights thereto, possible subnormal levels of income, a decline in value of the
underlying securities or lack of access to income during this period, and the
expense of enforcing its rights.

Reverse Repurchase Agreements. Each Fund may also enter into reverse repurchase
agreements which involve the sale of government securities held in its portfolio
to a bank with an agreement that the Fund will buy back the securities at a
fixed future date at a fixed price plus an agreed amount of "interest" which may
be reflected in the repurchase price. Reverse repurchase agreements are
considered to be borrowings by the Fund. Reverse repurchase agreements involve
the risk that the market value of securities purchased by a Fund with proceeds
of the transaction may decline below the repurchase price of the securities sold
by the Fund which it is obligated to repurchase. A Fund will also continue to be
subject to the risk of a decline in the market value of the securities sold
under the agreements because it will reacquire those securities upon effecting
their repurchase. To minimize various risks associated with reverse repurchase
agreements, the Fund will establish and maintain with the Fund's custodian a
separate account consisting of liquid securities, of any type or maturity, in an
amount at least equal to the repurchase prices of the securities (plus any
accrued interest thereon) under such agreements. A Fund will not enter into
reverse repurchase agreements and other borrowings exceeding in the aggregate
more than 33 1/3% of the market value of its total assets. Government Income
Fund will not make additional investments while borrowings (including reverse
repurchase agreements) are in excess of 5% of the Fund's total assets. A Fund
will enter into reverse repurchase agreements only with federally insured banks
or savings and loan associations which are approved in advance as being
creditworthy by the Trustees. Under procedures established by the Trustees, the
Adviser will monitor the creditworthiness of the banks involved.

Restricted Securities. The Funds may purchase securities that are not registered
("restricted securities") under the Securities Act of 1933 ("1933 Act"),
including commercial paper issued in reliance on section 4(2) of the 1933 Act
and securities offered and sold to "qualified institutional buyers" under Rule
144A under the 1933 Act. Each Fund will not invest more than 10% of its total
assets in illiquid investments, based upon a continuing review of the trading
markets for specific Section 4(2) paper or Rule 144A securities, that they are
liquid, they will not be subject to the 10% limit on illiquid investments. The
Trustees may adopt guidelines and delegate to the Adviser the daily function of
determining and monitoring the liquidity of restricted securities. The Trustees,
however, will retain sufficient oversight and be ultimately responsible for the
determinations. The Trustees will carefully monitor each Fund's investments in
these securities, focusing on such important factors, among others, as
valuation, liquidity and availability of information. This investment practice
could have the effect of increasing the level of illiquidity in a Fund if
qualified institutional buyers become for a time uninterested in purchasing
these restricted securities.

Options on Securities, Securities Indices and Currency. Each Fund may purchase
and write (sell) call and put options on any securities in which it may invest,
on any securities index based on securities in which it may invest or, in the
case of High Yield Bond Fund, on any currency in which Fund investments may be
denominated. These options may be listed on national domestic securities
exchanges or foreign securities exchanges or traded in the over-the-counter
market. Each Fund may write covered put and call options and purchase put and
call options to enhance total return, as a substitute for the purchase or sale
of securities or (in the case of High Yield Bond Fund) currency, or to protect
against declines in the value of portfolio securities and against increases in
the cost of securities to be acquired.


                                       16
<PAGE>

Writing Covered Options. A call option on securities or currency written by a
Fund obligates the Fund to sell specified securities or currency to the holder
of the option at a specified price if the option is exercised at any time before
the expiration date. A put option on securities or currency written by a Fund
obligates the Fund to purchase specified securities or currency from the option
holder at a specified price if the option is exercised at any time before the
expiration date. Options on securities indices are similar to options on
securities, except that the exercise of securities index options requires cash
settlement payments and does not involve the actual purchase or sale of
securities. In addition, securities index options are designed to reflect price
fluctuations in a group of securities or segment of the securities market rather
than price fluctuations in a single security. Writing covered call options may
deprive a Fund of the opportunity to profit from an increase in the market price
of the securities or foreign currency assets in its portfolio. Writing covered
put options may deprive a Fund of the opportunity to profit from a decrease in
the market price of the securities or foreign currency assets to be acquired for
its portfolio.

All call and put options written by the Funds are covered. A written call option
or put option may be covered by (i) maintaining cash or liquid securities,
either of which may be quoted or denominated in any currency, in a segregated
account maintained by the Fund's custodian with a value at least equal to the
Fund's obligation under the option, (ii) entering into an offsetting forward
commitment and/or (iii) purchasing an offsetting option or any other option
which, by virtue of its exercise price or otherwise, reduces the Fund's net
exposure on its written option position. A written call option on securities is
typically covered by maintaining the securities that are subject to the option
in a segregated account. A Fund may cover call options on a securities index by
owning securities whose price changes are expected to be similar to those of the
underlying index.

A Fund may terminate its obligations under an exchange traded call or put option
by purchasing an option identical to the one it has written. Obligations under
over-the-counter options may be terminated only by entering into an offsetting
transaction with the counterparty to such option. Such purchases are referred to
as "closing purchase transactions."

Purchasing Options. A Fund would normally purchase call options in anticipation
of an increase, or put options in anticipation of a decrease ("protective
puts"), in the market value of securities or (in the case of High Yield Bond
Fund) currencies of the type in which it may invest. A Fund may also sell call
and put options to close out its purchased options.

The purchase of a call option would entitle a Fund, in return for the premium
paid, to purchase specified securities or currency at a specified price during
the option period. A Fund would ordinarily realize a gain on the purchase of a
call option if, during the option period, the value of such securities or
currency exceeded the sum of the exercise price, the premium paid and
transaction costs; otherwise the Fund would realize either no gain or a loss on
the purchase of the call option.

The purchase of a put option would entitle a Fund, in exchange for the premium
paid, to sell specified securities or currency at a specified price during the
option period. The purchase of protective puts is designed to offset or hedge
against a decline in the market value of a Fund's portfolio securities or (in
the case of High Yield Bond Fund) the currencies in which they are denominated.
Put options may also be purchased by a Fund for the purpose of affirmatively
benefiting from a decline in the price of securities or currencies which it does
not own. A Fund would ordinarily realize a gain if, during the option period,
the value of the underlying securities or currency decreased below the exercise
price sufficiently to cover the premium and transaction costs; otherwise the
Fund would realize either no gain or a loss on the purchase of the put option.
Gains


                                       17
<PAGE>

and losses on the purchase of put options may be offset by countervailing
changes in the value of a Fund's portfolio securities.

Each Fund's options transactions will be subject to limitations established by
each of the exchanges, boards of trade or other trading facilities on which such
options are traded. These limitations govern the maximum number of options in
each class which may be written or purchased by a single investor or group of
investors acting in concert, regardless of whether the options are written or
purchased on the same or different exchanges, boards of trade or other trading
facilities or are held or written in one or more accounts or through one or more
brokers. Thus, the number of options which a Fund may write or purchase may be
affected by options written or purchased by other investment advisory clients of
the Adviser. An exchange, board of trade or other trading facility may order the
liquidation of positions found to be in excess of these limits, and it may
impose certain other sanctions.

Risks Associated with Options Transactions. There is no assurance that a liquid
secondary market on a domestic or foreign options exchange will exist for any
particular exchange-traded option or at any particular time. If a Fund is unable
to effect a closing purchase transaction with respect to covered options it has
written, the Fund will not be able to sell the underlying securities or
currencies or dispose of assets held in a segregated account until the options
expire or are exercised. Similarly, if the Fund is unable to effect a closing
sale transaction with respect to options it has purchased, it would have to
exercise the options in order to realize any profit and will incur transaction
costs upon the purchase or sale of underlying securities or currencies.

Reasons for the absence of a liquid secondary market on an exchange include the
following: (i) there may be insufficient trading interest in certain options;
(ii) restrictions may be imposed by an exchange on opening transactions or
closing transactions or both; (iii) trading halts, suspensions or other
restrictions may be imposed with respect to particular classes or series of
options; (iv) unusual or unforeseen circumstances may interrupt normal
operations on an exchange; (v) the facilities of an exchange or the Options
Clearing Corporation may not at all times be adequate to handle current trading
volume; or (vi) one or more exchanges could, for economic or other reasons,
decide or be compelled at some future date to discontinue the trading of options
(or a particular class or series of options). If trading were discontinued, the
secondary market on that exchange (or in that class or series of options) would
cease to exist. However, outstanding options on that exchange that had been
issued by the Options Clearing Corporation as a result of trades on that
exchange would continue to be exercisable in accordance with their terms.

A Fund's ability to terminate over-the-counter options is more limited than with
exchange-traded options and may involve the risk that broker-dealers
participating in such transactions will not fulfill their obligations. The
Adviser will determine the liquidity of each over-the-counter option in
accordance with guidelines adopted by the Trustees.

The writing and purchase of options is a highly specialized activity which
involves investment techniques and risks different from those associated with
ordinary portfolio securities transactions. The successful use of options
depends in part on the Adviser's ability to predict future price fluctuations
and, for hedging transactions, the degree of correlation between the options and
securities or currency markets.

Futures Contracts and Options on Futures Contracts. To seek to increase total
return or hedge against changes in interest rates, securities prices or (in the
case of High Yield Bond Fund) currency exchange rates, each Fund may purchase
and sell various kinds of futures contracts, and purchase


                                       18
<PAGE>

and write call and put options on these futures contracts. The Fund may also
enter into closing purchase and sale transactions with respect to any of these
contracts and options. The futures contracts may be based on various securities
(such as U.S. Government securities), securities indices, foreign currencies (in
the case of High Yield Bond Fund) and any other financial instruments and
indices. All futures contracts entered into by the Funds are traded on U.S. or
foreign exchanges or boards of trade that are licensed, regulated or approved by
the Commodity Futures Trading Commission ("CFTC").

Futures Contracts. A futures contract may generally be described as an agreement
between two parties to buy and sell particular financial instruments or
currencies for an agreed price during a designated month (or to deliver the
final cash settlement price, in the case of a contract relating to an index or
otherwise not calling for physical delivery at the end of trading in the
contract).

Positions taken in the futures markets are not normally held to maturity but are
instead liquidated through offsetting transactions which may result in a profit
or a loss. While futures contracts on securities or currency will usually be
liquidated in this manner, a Fund may instead make, or take, delivery of the
underlying securities or currency whenever it appears economically advantageous
to do so. A clearing corporation associated with the exchange on which futures
contracts are traded guarantees that, if still open, the sale or purchase will
be performed on the settlement date.

Hedging and Other Strategies. Hedging is an attempt to establish with more
certainty than would otherwise be possible the effective price or rate of return
on portfolio securities or securities that a Fund proposes to acquire or (in the
case of High Yield Bond Fund) the exchange rate of currencies in which portfolio
securities are quoted or denominated. When interest rates are rising or
securities prices are falling, a Fund can seek to offset a decline in the value
of its current portfolio securities through the sale of futures contracts. When
interest rates are falling or securities prices are rising, a Fund, through the
purchase of futures contracts, can attempt to secure better rates or prices than
might later be available in the market when it effects anticipated purchases.
High Yield Bond Fund may seek to offset anticipated changes in the value of a
currency in which its portfolio securities, or securities that it intends to
purchase, are quoted or denominated by purchasing and selling futures contracts
on such currencies.

A Fund may, for example, take a "short" position in the futures market by
selling futures contracts in an attempt to hedge against an anticipated rise in
interest rates or a decline in market prices or (in the case of High Yield Bond
Fund) foreign currency rates that would adversely affect the dollar value of the
Fund's portfolio securities. Such futures contracts may include contracts for
the future delivery of securities held by the Fund or securities with
characteristics similar to those of the Fund's portfolio securities. Similarly,
High Yield Bond Fund may sell futures contracts on any currencies in which its
portfolio securities are quoted or denominated or in one currency to hedge
against fluctuations in the value of securities denominated in a different
currency if there is an established historical pattern of correlation between
the two currencies.

If, in the opinion of the Adviser, there is a sufficient degree of correlation
between price trends for a Fund's portfolio securities and futures contracts
based on other financial instruments, securities indices or other indices, the
Fund may also enter into such futures contracts as part of its hedging strategy.
Although under some circumstances prices of securities in a Fund's portfolio may
be more or less volatile than prices of such futures contracts, the Adviser will
attempt to estimate the extent of this volatility difference based on historical
patterns and compensate for any differential by having the Fund enter into a
greater or lesser number of futures contracts or by attempting to achieve only a
partial hedge against price changes affecting the Fund's portfolio securities.

When a short hedging position is successful, any depreciation in the value of
portfolio securities will be substantially offset by appreciation in the value
of the futures position. On the other hand, any unanticipated appreciation in
the value of a Fund's portfolio securities would be substantially offset by a
decline in the value of the futures position.

On other occasions, a Fund may take a "long" position by purchasing futures
contracts. This would be done, for example, when the Fund anticipates the
subsequent purchase of particular securities when it has the necessary cash, but
expects the prices or (in the case of High Yield Bond Fund) currency exchange
rates then available in the applicable market to be less favorable than prices
that are currently available. A Fund may also purchase futures contracts as a
substitute for transactions in securities or (in the case of High Yield Bond
Fund) foreign currency, to alter the investment characteristics of or currency
exposure associated with portfolio securities or to gain or increase its
exposure to a particular securities market or currency.

Options on Futures Contracts. Each Fund may purchase and write options on
futures for the same purposes as its transactions in futures contracts. The
purchase of put and call options on futures contracts will give a Fund the right
(but not the obligation) for a specified price to sell or to purchase,
respectively, the underlying futures contract at any time during the option
period. As the purchaser of an option on a futures contract, a Fund obtains the
benefit of the futures position if prices move in a favorable direction but
limits its risk of loss in the event of an unfavorable price movement to the
loss of the premium and transaction costs.

The writing of a call option on a futures contract generates a premium which may
partially offset a decline in the value of a Fund's assets. By writing a call
option, a Fund becomes obligated, in exchange for the premium (upon exercise of
the option) to sell a futures contract if the option is exercised, which may
have a value higher than the exercise price. Conversely, the writing of a put
option on a futures contract generates a premium which may partially offset an
increase in the price of securities that a Fund intends to purchase. However,
the Fund becomes obligated (upon exercise of the option) to purchase a futures
contract if the option is exercised, which may have a value lower than the
exercise price. The loss incurred by a Fund in writing options on futures is
potentially unlimited and may exceed the amount of the premium received.

The holder or writer of an option on a futures contract may terminate its
position by selling or purchasing an offsetting option of the same series. There
is no guarantee that such closing transactions can be effected. A Fund's ability
to establish and close out positions on such options will be subject to the
development and maintenance of a liquid market.

Other Considerations. Each Fund will engage in futures and related options
transactions either for bona fide hedging purposes or to seek to increase total
return as permitted by the CFTC. To the extent that a Fund is using futures and
related options for hedging purposes, futures contracts will be sold to protect
against a decline in the price of securities (or the currency in which they are
quoted or denominated) that the Fund owns or futures contracts will be purchased
to protect the Fund against an increase in the price of securities (or, in the
case of High Yield Bond Fund, the currency in which they are quoted or
denominated) it intends to purchase. Each Fund will determine that the price
fluctuations in the futures contracts and options on futures used for hedging
purposes are substantially related to price fluctuations in securities held by
the Fund or securities or instruments which it expects to purchase. As evidence
of its hedging intent, each Fund expects that on 75% or more of the occasions on
which it takes a long futures or option position (involving the purchase of
futures contracts), the Fund will have purchased, or will be in the process of
purchasing, equivalent


                                       20
<PAGE>

amounts of related securities (or assets of High Yield Bond Fund denominated in
the related currency) in the cash market at the time when the futures or option
position is closed out. However, in particular cases, when it is economically
advantageous for a Fund to do so, a long futures position may be terminated or
an option may expire without the corresponding purchase of securities or other
assets.

To the extent that a Fund engages in nonhedging transactions in futures
contracts and options on futures, the aggregate initial margin and premiums
required to establish these nonhedging positions will not exceed 5% of the net
asset value of the Fund's portfolio, after taking into account unrealized
profits and losses on any such positions and excluding the amount by which such
options were in-the-money at the time of purchase.

Transactions in futures contracts and options on futures involve brokerage
costs, require margin deposits and, in the case of contracts and options
obligating a Fund to purchase securities or currencies, require the Fund to
establish with the custodian a segregated account consisting of cash or liquid
securities in an amount equal to the underlying value of such contracts and
options.

While transactions in futures contracts and options on futures may reduce
certain risks, these transactions themselves entail certain other risks. For
example, unanticipated changes in interest rates, securities prices or currency
exchange rates may result in a poorer overall performance for a Fund than if it
had not entered into any futures contracts or options transactions.

Perfect correlation between a Fund's futures positions and portfolio positions
will be impossible to achieve. There are no futures contracts based upon
individual securities, except certain U.S. Government securities. The only
futures contracts available to hedge the Funds' portfolios are various futures
on U.S. Government securities, securities indices and foreign currencies. In the
event of an imperfect correlation between a futures position and a portfolio
position which is intended to be protected, the desired protection may not be
obtained and a Fund may be exposed to risk of loss. In addition, it is not
possible to hedge fully or protect against currency fluctuations affecting the
value of securities denominated in foreign currencies because the value of such
securities is likely to fluctuate as a result of independent factors not related
to currency fluctuations.

Some futures contracts or options on futures may become illiquid under adverse
market conditions. In addition, during periods of market volatility, a commodity
exchange may suspend or limit trading in a futures contract or related option,
which may make the instrument temporarily illiquid and difficult to price.
Commodity exchanges may also establish daily limits on the amount that the price
of a futures contract or related option can vary from the previous day's
settlement price. Once the daily limit is reached, no trades may be made that
day at a price beyond the limit. This may prevent a Fund from closing out
positions and limiting its losses.

Lending of Securities. The Funds may lend portfolio securities to brokers,
dealers, and financial institutions if the loan is collateralized by cash or
U.S. Government securities according to applicable regulatory requirements. A
Fund may reinvest any cash collateral in short-term securities and money markets
funds. When a Fund lends portfolio securities, there is a risk that the borrower
may fail to return the securities involved in the transaction. As a result, the
Fund may incur a loss or, in the event of the borrower's bankruptcy, the Fund
may be delayed in or prevented from liquidating the collateral. It is a
fundamental policy of each Fund not to lend portfolio securities having a total
value exceeding 30% of its total assets.


                                       21
<PAGE>

Rights and Warrants. The Fund may purchase warrants and rights which are
securities permitting, but not obligating, their holder to purchase the
underlying securities at a predetermined price subject to the Fund's Fundamental
Investment Restriction. Generally, warrants and stock purchase rights do not
carry with them the right to receive dividends or exercise voting rights with
respect to the underlying securities, and they do not represent any rights in
the assets of the issuer. As a result, an investment in warrants and rights may
be considered to entail greater investment risk than certain other types of
investments. In addition, the value of warrant and rights does not necessarily
change with the value of the underlying securities, and they cease to have value
if they are not exercised on or prior to their expiration date. Investment in
warrants and rights increases the potential profit or loss to be realized from
the investment of a given amount of the Fund's assets as compared with investing
the same amount in the underlying stock.

Forward Commitment and When-Issued Securities. Each Fund may purchase securities
on a when-issued or forward commitment basis. "When-issued" refers to securities
whose terms are available and for which a market exists, but which have not been
issued. A Fund will engage in when-issued transactions with respect to
securities purchased for its portfolio in order to obtain what is considered to
be an advantageous price and yield at the time of the transaction. For
when-issued transactions, no payment is made until delivery is due, often a
month or more after the purchase. In a forward commitment transaction, a Fund
contracts to purchase securities for a fixed price at a future date beyond
customary settlement time.

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

On the date a Fund enters into an agreement to purchase securities on a when-
issued or forward commitment basis, the Fund will segregate in a separate
account cash or liquid securities, of any type or maturity, equal in value to
the Fund's commitment. These assets will be valued daily at market, and
additional cash or securities will be segregated in a separate account to the
extent that the total value of the assets in the account declines below the
amount of the when-issued commitments. Alternatively, a Fund may enter into
offsetting contracts for the forward sale of other securities that it owns.

Short-Term Trading and Portfolio Turnover. Short-term trading means the purchase
and subsequent sale of a security after it has been held for a relatively brief
period of time. Each Fund may engage in short-term trading in response to stock
market conditions, changes in interest rates or other economic trends and
developments, or to take advantage of yield disparities between various fixed
income securities in order to realize capital gains or improve income.
Short-term trading may have the effect of increasing portfolio turnover rate. A
high rate of portfolio turnover (100% or greater) involves correspondingly
greater brokerage transaction expenses and may make it more difficult for a Fund
to qualify as a regulated investment company for federal income tax purposes.
The Funds' portfolio turnover rate is set forth in the table under the caption
"Financial Highlights" in the Prospectus.

INVESTMENT RESTRICTIONS

Fundamental Investment Restrictions. The following investment restrictions will
not be changed for a Fund without the approval of a majority of that Fund's
outstanding voting securities which, as


                                       22
<PAGE>

used in the Prospectus and this Statement of Additional Information, means the
approval by the lesser of (1) the holders of 67% or more of that Fund's shares
represented at a meeting if more than 50% of that Fund's outstanding shares are
present in person or by proxy at that meeting or (2) more than 50% of that
Fund's outstanding shares.

Each Fund may not:

(1) Borrow money in an amount in excess of 33-1/3% of its total assets, and then
only as a temporary measure for extraordinary or emergency purposes (except that
it may enter into a reverse repurchase agreement within the limits described in
the Prospectus or this Statement of Additional Information), or pledge, mortgage
or hypothecate an amount of its assets (taken at market value) in excess of 15%
of its total assets, in each case taken at the lower of cost or market value.
For the purpose of this restriction, collateral arrangements with respect to
options, futures contracts, options on futures contracts and collateral
arrangements with respect to initial and variation margins are not considered a
pledge of assets.

(2) Underwrite securities issued by other persons except insofar as such Fund
may technically be deemed an underwriter under the Securities Act of 1933 in
selling a portfolio security.

(3) Purchase or retain real estate (including limited partnership interests but
excluding securities of companies, such as real estate investment trusts, which
deal in real estate or interests therein and securities secured by real estate),
or mineral leases, commodities or commodity contracts (except contracts for the
future delivery of fixed income securities, stock index and currency futures and
options on such futures) in the ordinary course of its business. Each Fund
reserves the freedom of action to hold and to sell real estate or mineral
leases, commodities or commodity contracts acquired as a result of the ownership
of securities.

(4) Invest in direct participation interests in oil, gas or other mineral
exploration or development programs.

(5) Make loans to other persons except by the purchase of obligations in which
such Fund is authorized to invest and by entering into repurchase agreements;
provided that a Fund may lend its portfolio securities not in excess of 30% of
its total assets (taken at market value). Not more than 10% of a Fund's total
assets (taken at market value) will be subject to repurchase agreements maturing
in more than seven days. For these purposes the purchase of all or a portion of
an issue of debt securities shall not be considered the making of a loan.

(6) Purchase the securities of any issuer if such purchase, at the time thereof,
would cause more than 5% of its total assets (taken at market value) to be
invested in the securities of such issuer, other than securities issued or
guaranteed by the United States or any state or political subdivision thereof,
or any political subdivision of any such state, or any agency or instrumentality
of the United States, any state or political subdivision thereof, or any
political subdivision of any such state. In applying these limitations, a
guarantee of a security will not be considered a security of the guarantor,
provided that the value of all securities issued or guaranteed by that
guarantor, and owned by the Fund, does not exceed 10% of the Fund's total
assets. In determining the issuer of a security, each state and each political
subdivision agency, and instrumentality of each state and each multi-state
agency of which such state is a member is a separate issuer. Where securities
are backed only by assets and revenues of a particular instrumentality, facility
or subdivision, such entity is considered the issuer.


                                       23
<PAGE>

(7) Invest in companies for the purpose of exercising control or management.

(8) Purchase or retain in its portfolio any securities issued by an issuer any
of whose officers, directors, trustees or security holders is an officer or
Trustee of such Fund, or is a member, partner, officer or Director of the
Adviser, if after the purchase of the securities of such issuer by such Fund one
or more of such persons owns beneficially more than 1/2 of 1% of the shares or
securities, or both, all taken at market value, of such issuer, and such persons
owning more than 1/2 of 1% of such shares or securities together own
beneficially more than 5% of such shares or securities, or both, all taken at
market value.

(9) Purchase any securities or evidences of interest therein on margin, except
that each Fund may obtain such short-term credit as may be necessary for the
clearance of purchases and sales of securities and each Fund may make deposits
on margin in connection with futures contracts and related options.

(10) Sell any security which such Fund does not own unless by virtue of its
ownership of other securities it has at the time of sale a right to obtain
securities without payment of further consideration equivalent in kind and
amount to the securities sold and provided that if such right is conditional the
sale is made upon equivalent conditions.

(11) Knowingly invest in securities which are subject to legal or contractual
restrictions on resale or for which there is no readily available market (e.g.,
trading in the security is suspended or market makers do not exist or will not
entertain bids or offers), except for repurchase agreements, if, as a result
thereof more than 10% of such Fund's total assets (taken at market value) would
be so invested.

(12) Issue any senior security (as that term is defined in the Investment
Company Act of 1940 (the "Investment Company Act") if such issuance is
specifically prohibited by the Investment Company Act or the rules and
regulations promulgated thereunder. For the purpose of this restriction,
collateral arrangements with respect to options, futures contracts and options
on futures contracts and collateral arrangements with respect to initial and
variation margins are not deemed to be the issuance of a senior security.

(13) Government Income Fund may not invest more than 25% of its total assets
(taken at market value) in the securities of issuers engaged in any one
industry. High Yield Bond Fund may not invest more than 25% of its total assets
(taken at market value) in the securities of issuers engaged in any one
industry, except that the Fund may invest up to 40% of the value of its total
assets in the securities of issuers engaged in the electric utility and
telephone industries. The Adviser follows a policy of not causing the Fund to
invest more than 25% of its total assets in the securities of issuers engaged in
the electric utility industry or the telephone industry unless yields available
for four consecutive weeks in the four highest rating categories on new issue
bonds in this industry (issue size of $50 million or more) have averaged greater
than the yields of new issue long-tern industrial bonds similarly rated (issue
size of $50 million or more) and, in the opinion the Adviser, the relative
return available from the electric utility or telephone industry and the
relative risk, marketability, quality and availability of securities of this
industry justifies such an investment. Obligations issued or guaranteed by the
U.S. Government or its agencies and instrumentalities are not subject to the
foregoing 25% limitation. In addition, for purposes of this limitation,
determinations of what constitutes an industry are made in accordance with
specific industry codes set forth in the Standard Industrial Classification
Manual and without considering groups of industries (e.g., all utilities, to be
an industry).


                                       24
<PAGE>

(14) Purchase securities of any issuer (other than securities issued or
guaranteed by the U.S. Government or its agencies or instrumentalities) if such
purchase, at the time thereof, would cause a Fund to hold more than 10% of any
class of securities of such issuer. For this purpose, all indebtedness of an
issuer shall be deemed a single class and all preferred stock of an issuer shall
be deemed a single class.

Non-Fundamental Investment Restrictions. The following investment restrictions
are designated as non-fundamental and may be changed by the Trustees without
shareholder approval.

(1) Neither Fund may purchase a security if, as a result, (i) more than 10% of
the Fund's total assets would be invested in the securities of other investment
companies, (ii) the Fund would hold more than 3% of the total outstanding voting
securities of any one investment company, or (iii) more than 5% of the Fund's
total assets would be invested in the securities of any one investment company.
These limitations do not apply to (a) the investment of cash collateral,
received by the Fund in connection with lending of the Fund's portfolio
securities, in the securities of open-end investment companies or (b) the
purchase of shares of any investment company in connection with a merger,
consolidation, reorganization or purchase of substantially all of the assets of
another investment company. Subject to the above percentage limitations, each
Fund may, in connection with the John Hancock Group of Funds Deferred
Compensation Plan for Independent Trustees/Directors, purchase securities of
other investment companies within the John Hancock Group of Funds.

If a percentage restriction or rating restriction on investment or utilization
of assets is adhered to at the time an investment is made or assets are so
utilized, a later change in percentage resulting from changes in the value of a
Fund's portfolio securities or a later change in the rating of a portfolio
security will not be considered a violation of policy.

THOSE RESPONSIBLE FOR MANAGEMENT

The business of each Fund is managed by its Trustees who elect officers who are
responsible for the day-to-day operations of the Funds and who execute policies
formulated by the Trustees. Several of the officers and Trustees of the Fund are
also Officers and Directors of the Adviser or Officers and Directors of the
Funds' principal distributor, John Hancock Funds, Inc. ("John Hancock Funds").

INVESTMENT ADVISORY AND OTHER SERVICES

The Adviser, located at 101 Huntington Avenue, Boston, Massachusetts 02199-7603,
was organized in 1968 and has more than $30 billion in assets under management
in its capacity as investment adviser to the Funds and the other mutual funds
and publicly traded investment companies in the John Hancock group of funds,
having a combined total of over 1,400,000 shareholders. The Adviser is an
affiliate of the Life Company, one of the most recognized and respected
financial institutions in the nation. With total assets under management of more
than $100 billion, the Life Company is one of the ten largest life insurance
companies in the United States, and carries a high rating from Standard & Poor's
and A.M. Best's. Founded in 1862, the Life Company has been serving clients for
over 130 years.


The Funds have entered into an investment management contract (the "Advisory
Agreement") with the Adviser which was approved by the Funds' shareholders.
Pursuant to the Advisory Agreements, the Adviser will: (a) furnish continuously
an investment program for the Fund and determine, subject to the overall
supervision and review of the Trustees, which investments should be purchased,
held, sold or exchanged and (b) provide supervision over all aspects of the
Fund's operations except those which are delegated to a custodian, transfer
agent or other agent.

Each Fund bears all cost of its organization and operation, including expenses
of preparing, printing and mailing all shareholders' reports, notices,
prospectuses, proxy statements and reports to regulatory agencies; expenses
relating to the issuance, registration and qualification of shares; government
fees; interest charges; expenses of furnishing to shareholders their account
statements; taxes; expenses of redeeming shares; brokerage and other expenses
connected with the execution of portfolio securities transactions; expenses
pursuant to each Fund's plan of distribution; fees and expenses of custodian
including those for keeping books and accounts and calculating the net asset
value of shares; fees and expenses of transfer agents and dividend disbursing
agents; legal, accounting, financial, management, tax and auditing fees and
expenses of the Fund (including and allocable portion of the cost of the
Adviser's employees rendering such services to the Fund); the compensation and
expenses of Trustees who are not other wise affiliated with the Trust, the
Adviser or any of their affiliates; expenses of Trustees' and shareholders'
meeting; trade association memberships; insurance premiums; and any
extraordinary expenses.

As compensation for its services under the Advisory Agreements, each Fund pays
the Adviser a monthly a fee based on a stated percentage of the average of the
daily net assets of each Fund as follows:

                        Government Income Fund

                                                             Fee
Average Daily Net Assets                                 (Annual Rate)
- ------------------------                                 -------------

First $200 million                                          0.650%
Next $300 million                                           0.625%
Over $500 million                                           0.600%


                        High Yield Bond Fund

                                                              Fee
Average Daily Net Assets                                 (Annual Rate)
- ------------------------                                 -------------

First $75 million                                           0.625%
Next $75 million                                            0.5625%
Over $150 million                                           0.500%


                                       35
<PAGE>

From time to time, the Adviser may reduce its fee or make other arrangements to
limit the Fund's expenses to a specified percentage of average daily net assets.
The Adviser retains the right to reimpose a fee and recover any other payments
to the extent that, at the end of any fiscal year, the Fund's annual expenses
fall below this limit.

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

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

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

Each Advisory Agreement was approved by all of the Trustees. The Advisory
Agreement and the Distribution Agreement discussed below will continue in effect
from year to year, provided that its continuance is approved annually both (i)
by the holders of a majority of the outstanding voting securities of the Trust
or by the Trustees, and (ii) by a majority of the Trustees who are not parties
to the Agreement, or "interested persons" of any such parties. Both Agreements
may be terminated on 60 days written notice by any party or by a vote of a
majority of the outstanding voting securities of the Funds and will terminate
automatically if assigned.

Advisory fees payable by the Funds to the Adviser, were as follows:

                       Government Income Fund         High Yield Bond Fund
                       ----------------------         --------------------

Administrative Services Agreement. Each Fund previously was a party to an
administrative services agreement with TFMC (the "Services Agreement"), pursuant
to which TFMC performed bookkeeping and accounting services and functions,
including preparing and maintaining various accounting books, records and other
documents and keeping such general ledgers and portfolio accounts as are
reasonably necessary for the operation of the Funds. Other administrative
services included communications in response to shareholder inquiries and
certain printing expenses of various financial reports. In addition, such staff
and office space, facilities and equipment was provided as necessary to provide
administrative services to the Funds. The Services Agreement was amended in
connection with the appointment of the Adviser as adviser to the Fund to permit
services under the Agreement to be provided to the Funds by the Adviser and its
affiliates. The Services Agreement was terminated during the 1995 fiscal year.

The following amounts for each of the Funds reflects the total of administrative
services fees paid to the Adviser for the fiscal year ended October 31, 1995:

      Government Income Fund - $16,694      High Yield Bond Fund - $13,697

Accounting and Legal Services Agreement. The Trust, on behalf each Fund, is a
party to an Accounting and Legal Services Agreement with the Adviser. Pursuant
to this agreement, the Adviser provides each Fund with certain tax, accounting
and legal services. For the fiscal year ended October 31, 1996, Government
Income Fund and High Yield Bond Fund paid the Adviser $96,304 and $37,927 for
services under this agreement. For the period from November 1, 1996 to May 31,
1997, Government Income Fund and High Yield Bond Fund paid the Adviser $59,313
and $42,106 for services under this agreement.

In order to avoid conflicts with portfolio trades for the Fund, the Adviser and
the Fund have adopted extensive restrictions on personal securities trading by
personnel of the Adviser and its affiliates. Some of these restrictions are:
pre-clearance for all personal trades and a ban on the purchase of initial
public offerings, as well as contributions to specified charities of profits on
securities held for less than 91 days. These restrictions are a continuation of
the basic principle that the interests of the Fund and its shareholders come
first.

DISTRIBUTION CONTRACTS

The Fund has a Distribution Agreement with John Hancock Funds. Under the
agreement, John Hancock Funds is obligated to use its best efforts to sell
shares of each class of the Fund. Shares of the Fund are also sold by selected
broker-dealers (the "Selling Brokers") which have entered into selling agency
agreements with John Hancock Funds. John Hancock Funds accepts orders for the
purchase of the shares of the Fund which are continually offered at net asset
value next determined, plus any applicable sales charge, if any. In connection
with the sale of Fund shares, John Hancock Funds and Selling Brokers receive
compensation from a sales charge imposed, in the case of Class A shares, at the
time of sale. In the case of Class B or Class C shares, the broker receive
compensation immediately but John Hancock Funds is compensated on a deferred
basis. John Hancock Funds may pay extra compensation to financial services firms
selling large amounts of fund shares. This compensation would be calculated as a
percentage of fund shares sold by the firm.

For the fiscal years ended October 31, 1995, 1996, and for the period from
November 1, 1996 to May 31, 1997, the following amounts reflect (a) the total
underwriting commissions for sales of the


                                       37
<PAGE>

Funds' Class A shares and (b) the portion of such amount retained by John
Hancock Funds. The remainder of the underwriting commissions were reallowed to
dealers.

Government Income and High Yield Bond Funds Trustees adopted Distribution Plans
with respect to each Class of shares (the "Plans") pursuant to Rule 12b-1 under
the Investment Company Act of 1940. Under the Plans, each Fund will pay
distribution and service fees at an aggregate annual rate of up to 0.25% for
Class A shares and 1.00% for Class B and Class C shares, of that Fund's average
daily net assets attributable to shares of that class. However, the service fee
will not exceed 0.25% of each Fund's average daily net assets attributable to
each class of shares. In each case, up to 0.25% is for service expenses and the
remaining amount is for distribution expenses. The distribution fees will be
used to reimburse John Hancock Funds for their distribution expenses, including
but not limited to: (i) initial and ongoing sales compensation to Selling
Brokers and others (including affiliates of John Hancock Funds) engaged in the
sale of each Fund's shares; (ii) marketing, promotional and overhead expenses
incurred in connection with the distribution of each Fund's shares; and (iii)
with respect to Class B and Class C shares only, interest expenses on
unreimbursed distribution expenses. The service fees will by used to compensate
Selling Brokers and others for providing personal and account maintenance
services to shareholders. In the event the John Hancock Funds is not fully
reimbursed for payments they make under the Class A Plan, these expenses will
not carried beyond twelve months from the date they were incurred. Unreimbursed
expenses under the Class B and Class C Plans will be carried forward together
with interest on the balance of these unreimbursed expenses. The Funds do not
treat unreimbursed expenses under Class B and Class C Plans as a liability of
the Funds, because the Trustees may terminate the Class B and/or Class C Plans
at any time. For the fiscal period ended May 31, 1997 an aggregate of
$10,894,166 of distribution expenses or 6.53% of the average net assets of
Government Income Fund's Class B shares was not reimbursed or recovered by John
Hancock Funds through the receipt of deferred sales charges or Rules 12b-1 fees
in prior periods. For the same period, an aggregate of $8,666,437 of
distribution expenses or 2.80% of the average net assets of High Yield Bond
Fund's Class B shares was not reimbursed or recovered by John Hancock Funds
through the receipt of deferred sales charges or Rule 12b-1 fees in prior
periods. Class C shares of High Yield Bond Fund did not commence operations
until May 1, 1998; therefore, there are no unreimbursed expenses to report.

The Plans were approved by a majority of the voting securities of each Fund. The
Plans and all amendments were approved by the Trustees, including a majority of
the Trustees who are not interested persons of each Fund and who have no direct
or indirect financial interest in the operation of the Plans ( the "Independent
Trustees"), by votes cast in person at meetings called for the purpose of voting
on such Plans.

Pursuant to the Plans, at least quarterly, John Hancock Funds provide each Fund
with a written report of the amounts expended under the Plans and the purpose
for which these expenditures were made. The Trustees review these reports on a
quarterly basis to determine their continued appropriateness.


                                       38
<PAGE>

Each of the Plans provides that it will continue in effect only so long as their
continuance is approved at least annually by a majority of both the Trustees and
Independent Trustees. Each of the Plans may be terminated without penalty, (a)
by vote of a majority of the Independent Trustees, (b) by a vote of a majority
of the applicable Fund's outstanding shares of the applicable class upon 60
days' written notice to John Hancock Funds, and (c) automatically in the event
of assignment. Each of the Plans further provides that it may not be amended to
increase the maximum amount of the fees for the services described therein
without the approval of a majority of the outstanding shares of the class of the
applicable Fund which has voting rights to that Plan. Each of the Plans provide
that no material amendment to the Plan will be effective unless it is approved
by a vote of a majority of the Trustees and the Independent Trustees of the
applicable Fund. The holders of Class A, Class B and Class C shares have
exclusive voting rights with respect to the Plan applicable to their respective
class of shares. In adopting the Plans, the Trustees concluded that, in their
judgment, these is a reasonable likelihood that the Plans will benefit the
holders of the applicable class of shares of affected Fund.

Amounts paid to John Hancock Funds by any class of shares of each Fund will not
be used to pay the expenses incurred with respect to any other class of shares
of that Fund; provided, however, that expenses attributable to each Fund as a
whole will be allocated, to the extent permitted by law, according to a formula
based upon gross sales dollars and/or average daily net assets of each such
class, as may be approved from time to time by vote of a majority of Trustees.
From time to time, the Funds may participate in joint distribution activities
with other Funds and the costs of those activities will be borne by each Fund in
proportion to the relative net asset value of the participating Funds.

During the period from November 1, 1996 to May 31, 1997, the Funds paid the
Distributors the following amounts of expenses with respect to the Class A
shares and Class B shares of each of the Funds. Class C shares of High Yield
Bond Fund did not commence operations until May 1, 1998; therefore, there are no
expenses to report.

NET ASSET VALUE

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

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

Equity securities traded on a principal exchange or NASDAQ National Market
Issues are generally valued at last sale price on the day of valuation.
Securities in the aforementioned category for which no sales are reported and
other securities traded over-the-counter are generally valued at the mean
between the current closing bid and asked prices.

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

Foreign securities are valued on the basis of quotations from the primary market
in which they are traded. Any assets or liabilities expressed in terms of
foreign currencies are translated into U.S. dollars by the custodian bank based
on London currency exchange quotations as of 5:00 p.m., London time (12:00 noon,
New York time) on the date of any determination of the Fund's NAV. If quotations
are not readily available, or the value has been materially affected by the
events occurring after closing of a foreign market, assets are valued by a
method that Trustees believe accurately reflects fair value.

The NAV for each fund and class is determined each business day at the close of
regular trading on the New York Stock Exchange (typically 4:00 p.m. Eastern
Time) by dividing a class net assets by the number of its shares outstanding. On
any day an international market is closed and the New York Stock Exchange is
open, any foreign securities will be valued at the prior day's close with the
current day's exchange rate. Trading of foreign securities may take place on
Saturdays and U.S. business holidays on which a Fund's NAV is not calculated.
Consequently, a Fund's portfolio securities may trade and the NAV of the Fund's
redeemable securities may be significantly affected on days when a shareholder
has no access to the Fund.

INITIAL SALES CHARGE ON CLASS A SHARES

Shares of the Funds are offered at a price equal to their net asset value plus a
sales charge which, at the option of the purchaser, may be imposed either at the
time of purchase (the "initial sales charge alternative") or on a contingent
deferred basis (the "deferred sales charge alternative"). Share certificates
will not be issued unless requested by the shareholder in writing, and then only
will be issued for full shares. The Trustees of each Fund reserve the right to
change or waive each Fund's minimum investment requirements and to reject any
order to purchase shares (including purchase by exchange) when in the judgment
of the Adviser such rejection is in the respective Fund's best interest.


                                       40
<PAGE>

The sales charges applicable to purchases of Class A shares of the Funds are
described in the Prospectus. Methods of obtaining reduced sales charges referred
to generally in the Prospectus are described in detail below. In calculating the
sales charge applicable to current purchases of Class A shares, the investor is
entitled to accumulate current purchases with the greater of the current value
(at offering price) of the Class A shares of the Funds, owned by the investor,
or if John Hancock Signature Services, Inc. ("Signature Services") is notified
by the investor's dealer or the investor at the time of the purchase, the cost
of the Class A shares owned.


Without Sales Charge. Class A shares may be offered without a front-end sales
charge or CDSC to various individuals and institutions as follows:

o     A Trustee or officer of the Trust; a Director or officer of the Adviser
      and its affiliates or Selling Brokers; employees or sales representatives
      of any of the foregoing; retired officers, employees or Directors of any
      of the foregoing; a member of the immediate family (spouse, children,
      grandchildren, mother, father, sister, brother, mother-in-law,
      father-in-law, daughter-in-law, son-in-law, niece, nephew, grandparents
      and domestic partner) of any of the foregoing, or any fund, pension,
      profit sharing or other benefit plan of the individuals described above.

o     A broker, dealer, financial planner, consultant or registered investment
      advisor that has entered into a signed agreement with John Hancock Funds
      providing specifically for the use of Fund shares in fee-based investment
      products or services made available to their clients.

o     A former participant in an employee benefit plan with John Hancock funds,
      when he or she withdraws from his or her plan and transfers any or all of
      his or her plan distributions directly to the Fund.

o     A member of a class action lawsuit against insurance companies who is
      investing settlement proceeds.

o     Retirement plans participating in Merrill Lynch servicing programs, if the
      Plan has more than $3 million in assets or 500 eligible employees at the
      date the Plan Sponsor signs the Merrill Lynch Recordkeeping Service
      Agreement. See your Merrill Lynch financial consultant for further
      information.

o     Retirement plans investing through the PruArray Program sponsored by
      Prudential Securities.

o     Existing full service clients of the Life Company who were group annuity
      contract holders as of September 1, 1994, and participant directed
      retirement plans with at least 100 eligible employees at the inception of
      the Fund account. Each of these investors may purchase Class A shares with
      no initial sales charge. However, for each Fund, if the shares are
      redeemed within 12 months after the end of the calendar year in which the
      purchase was made, a CDSC will be imposed at the following rate:

Class A shares may also be purchased without an initial sales charge in
connection with certain liquidation, merger or acquisition transactions
involving other investment companies or personal holding companies.

Combination Privilege. In calculating the sales charge applicable to purchases
of Class A shares made at one time, the purchases will be combined to reduce
sales charges if made by (a) an individual, his or her spouse and their children
under the age of 21, purchasing securities for his or their own account, (b) a
trustee or other fiduciary purchasing for a single trust, estate or fiduciary
account and (c) groups which qualify for the Group Investment Program (see
below). Further information about combined purchases, including certain
restrictions on combined group purchases, is available from Signature Services
or a Selling Broker's representative.


Accumulation Privilege. Investors (including investors combining purchases) who
are already Class A shareholders may also obtain the benefit of the reduced
sales charge by taking into account not only the amount being invested but also
the investor's purchase price or current value of the Class A shares of all John
Hancock funds which carry a sales charge already held by such person. Class A
shares of John Hancock money market funds will only be eligible for the
accumulation privilege if the investor has previously paid a sales charge on the
amount of those shares. Retirement plan investors may include the value of Class
B shares if class B shares held are greater than $1 million. Retirement plans
must notify Signature Services to utilize.


Group Investment Program. Under the Combination and Accumulation Privileges, all
members of a group may combine their individual purchases of Class A shares to
potentially qualify for breakpoints in the sales charge schedule. This feature
is provided to any group which (1) has been in existence for more than six
months, (2) has a legitimate purpose other than the purchase of mutual fund
shares at a discount for its members, (3) utilizes salary deduction or similar
group methods of payment, and (4) agrees to allow sales materials of the fund in
its mailings to members at a reduced or no cost to John Hancock Funds.


Letter of Intention. Reduced sales charges are also applicable to investments
made pursuant to a Letter of Intention (the "LOI"), which should be read
carefully prior to its execution by an investor. Each Fund offers two options
regarding the specified period for making investments under the LOI. All
investors have the option of making their investments over a specified period of
thirteen (13) months. Investors who are using the Fund as a funding medium for a
retirement plan, however, may opt to make the necessary investments called for
by the LOI over a forty- eight (48) month period. These retirement plans include
Traditional, Roth and Education IRAs, SEP, SARSEP, 401(k),403(b) (including
TSAs), SIMPLE IRA, SIMPLE 401(k), Money Purchase Pension, Profit Sharing and
Section 457 plans. Such an investment (including accumulations and combinations
but not including reinvested dividends) must aggregate $100,000 or more invested
during the specified period from the date of the LOI or from a date within
ninety (90) days prior thereto, upon written request to Signature Services. The
sales charge applicable to all amounts invested under the LOI is computed as if
the aggregate amount intended to be invested had been invested immediately. If
such aggregate amount is not actually invested, the difference in the sales
charge actually paid and



                                       42
<PAGE>


the sales charge payable had the LOI not been in effect is due from the
investor. However, for the purchases actually made with the specified period
(either 13 or 48 months), the sales charge applicable will not be higher than
that which would have been applied (including accumulations and combinations)
had the LOI been for the amount actually invested.


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

DEFERRED SALES CHARGE ON CLASS B AND CLASS C SHARES

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

Contingent Deferred Sales Charge. Class B and Class C shares which are redeemed
within six years or one year of purchase, respectively will be subject to a
contingent deferred sales charge ("CDSC") at the rates set forth in the
Prospectus as a percentage of the dollar amount subject to the CDSC. The charge
will be assessed on an amount equal to the lesser of the current market value or
the original purchase cost of the Class B or Class C shares being redeemed. No
CDSC will be imposed on increases in account value above the initial purchase
prices, including all shares derived from reinvestment of dividends or capital
gains distributions.


Class B shares are not available to full-service retirement plans administered
by Signature Services or the Life Company that had more than 100 eligible
employees at the inception of the Fund account.


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

In determining whether a CDSC applies to a redemption, the calculation will be
determined in a manner that results in the lowest possible rate being charged.
It will be assumed that your redemption comes first from shares you have held
beyond the six-year CDSC redemption period for Class B or one year CDSC
redemption period for Class C, or those you acquired through dividend and
capital gain reinvestment, and next from the share you have held the longest
during the six-year period for Class B shares. For this purpose, the amount of
any increase in a share's value above its initial purchase price is not regarded
as a share exempt from CDSC. Thus, when a share that has appreciated in value is
redeemed during the CDSC period, a CDSC is assessed only on its initial purchase
price.


                                       43
<PAGE>

When requesting a redemption for a specific dollar amount, please indicate if
you require the proceeds to equal the dollar amount requested. If not indicated,
only the specified dollar amount will be redeemed from your account and the
proceeds will be less any applicable CDSC.

Example:

You have purchased 100 shares at $10 per share. The second year after your
purchase, your investment's net asset value per share has increased by $2 to
$12, and you have gained 10 additional shares through dividend reinvestment. If
you redeem 50 shares at this time your CDSC will be calculated as follows:

      o Proceeds of 50 shares redeemed at $12 per shares (50 x 12)   $600.00
      o*Minus Appreciation ($12 - $10) x 100 shares                  (200.00)
      o Minus proceeds of 10 shares not subject to CDSC 
        (dividend reinvestment)                                      (120.00)
                                                                     ------- 
      o Amount subject to CDSC                                       $280.00

      *The appreciation is based on all 100 shares in the lot not just the
       shares being redeemed.

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

Waiver of Contingent Deferred Sales Charge. The CDSC will be waived on
redemptions of Class B and Class C shares and of Class A shares that are subject
to a CDSC, unless indicated otherwise, in the circumstances defined below:

For all account types:

*     Redemptions made pursuant to the Fund's right to liquidate your account if
      you own shares worth less than $1,000.

*     Redemptions made under certain liquidation, merger or acquisition
      transactions involving other investment companies or personal holding
      companies.


*     Redemptions due to death or disability. (Does not apply to Trust accounts
      unless trust is being dissolved.)

*     Redemptions made under the Reinstatement Privilege, as described in "Sales
      Charge Reductions and Waivers" in the Prospectus.

*     Redemption of Class B or Class C shares where the proceeds are used to
      purchase a John Hancock Declaration Annuity.


*     Redemptions of Class B (but not Class C) shares made under a periodic
      withdrawal plan, or redemptions for fees charged by planners or advisors
      for advisory services, as long as your annual redemptions do not exceed
      12% of your account value, including reinvested dividends, at the time you
      established your periodic withdrawal plan and 12% of the value of


                                       44
<PAGE>

      subsequent investments (less redemptions) in that account at the time you
      notify Signature Services. (Please note that this waiver does not apply to
      periodic withdrawal plan redemptions of Class A or Class C shares that are
      subject to a CDSC.)

*     Redemptions by Retirement plans participating in Merrill Lynch servicing
      programs, if the Plan has less than $3 million in assets or 500 eligible
      employees at the date the Plan Sponsor signs the Merrill Lynch
      Recordkeeping Service Agreement. See your Merrill Lynch financial
      consultant for further information.


*     Redemptions of Class A or Class C shares by retirement plans that invested
      through the PruArray Program sponsored by Prudential Securities.

For Retirement Accounts (such as Traditional, Roth and Education IRAs, SIMPLE
IRA, SIMPLE 401(k), Rollover IRA, TSA, 457, 403(b), 401(k), Money Purchase
Pension Plan, Profit-Sharing Plan and other plans as described in the Internal
Revenue Code) unless otherwise noted.


*     Redemptions made to effect mandatory or life expectancy distributions
      under the Internal Revenue Code.

*     Returns of excess contributions made to these plans.

*     Redemptions made to effect distributions to participants or beneficiaries
      from employer sponsored retirement plans under Section 401(a) of the Code
      (such as 401(k), Money Purchase Pension Plan, Profit-Sharing Plan).

*     Redemptions from certain IRA and retirement plans that purchased shares
      prior to October 1, 1992 and certain IRA plans that purchased shares prior
      to May 15, 1995.

Please see matrix for reference.

SPECIAL REDEMPTIONS

Although the Funds would not normally do so, each Fund has the right to pay the
redemption price of shares of the Fund in whole or in part in portfolio
securities as prescribed by the Trustees. When the shareholder sells portfolio
securities received in this fashion, the shareholder will incur a brokerage
charge. Any such security would be valued for the purpose of making such payment
at the same value as used in determining the Fund's net asset value. Each Fund
has however elected to be governed by Rule 18f-1 under the Investment Company
Act. Under that rule, the Funds must redeem their shares for cash except to the
extent to that the redemption payments to any shareholder during any 90-day
period would exceed the lesser of $250,000 or 1% of the applicable Fund's net
asset value at the beginning of such period.

ADDITIONAL SERVICES AND PROGRAMS

Exchange Privilege. The funds permit exchanges of shares of any class of a fund
for shares of the same class in any other John Hancock fund offering that class.

Exchanges between funds with shares that are not subject to a CDSC are based on
their respective net asset values. No sales charge or transactions charge is
imposed. Shares of the Fund which are subject to a CDSC may be exchanged into
shares of any of the other John Hancock funds that are subject to a CDSC without
incurring the CDSC; however, the shares acquired in an exchange will be subject
to the CDSC schedule of the shares acquired if and when such shares are redeemed
(except that shares exchanged into John Hancock Short-Term Strategic Income Fund
and John Hancock Intermediate Maturity Government Fund will retain the exchanged
fund's CDSC schedule). For purposes of computing the CDSC payable upon
redemption of shares acquired in an exchange, the holding period of the original
shares is added to the holding period of the shares acquired in an exchange.

If a shareholder exchanges Class B shares purchased prior to January 1, 1994
(except John Hancock Short-Term Strategic Income Fund) for Class B shares of any
other John Hancock fund, the acquired shares will continue to be subject to the
CDSC schedule that was in effect when the exchanged shares were purchased.

Each Fund reserves the right to require that previously exchanged shares (and
reinvested dividends) be in the Fund for 90 days before a shareholder is
permitted a new exchange.

Each Fund may refuse any exchange order. Each Fund may change or cancel its
exchange policies at any time, upon 60 days' notice to its shareholders.

An exchange of shares is treated as a redemption of shares of one fund and the
purchase of shares of another for Federal Income Tax purposes. An exchange may
result in a taxable gain or loss. See "TAX STATUS".

Systematic Withdrawal Plan. Each Fund permits the establishment of a Systematic
Withdrawal Plan. Payments under this plan represent proceeds from the redemption
of shares of the applicable Fund. Since the redemption price of the shares of a
Fund may be more or less than the shareholder's cost, depending upon the market
value of the securities owned by each Fund at the time of redemption, the
distribution of cash pursuant to this plan may result in realization of gain or
loss for purposes of Federal, state and local income taxes. The maintenance of a
Systematic 


                                       47
<PAGE>

Withdrawal Plan concurrently with purchases of additional shares of the Funds
could be disadvantageous to a shareholder because of the initial sales charge
payable on such purchases of Class A shares and the CDSC imposed on redemptions
of Class B and Class C shares and because redemptions are taxable events.
Therefore, a shareholder should not purchase shares at the same time a
Systematic Withdrawal Plan is in effect. The Funds reserve the right to modify
or discontinue the Systematic Withdrawal Plan of any shareholder on 30 days'
prior written notice to such shareholder, or to discontinue the availability of
such plan in the future. The shareholder may terminate the plan at any time by
giving proper notice to Signature Services.

Monthly Automatic Accumulation Program ("MAAP"). The program is explained in the
Prospectus. The program, as it relates to automatic investment checks, is
subject to the following conditions:

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

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

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

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

To protect the interests of other investors in each Fund, each Fund may cancel
the reinvestment privilege of any parties that, in the opinion of the Funds, are
using market timing strategies or making more than seven exchanges per owner or
controlling party per calendar year. Also, the Funds may refuse any reinvestment
request.

Each Fund may change or cancel its reinvestment policies at any time.

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

Retirement plans participating in Merrill Lynch's servicing programs:

Class A shares are available at net asset value for plans with $3 million in
plan assets or 500 eligible employees at the date the Plan Sponsor signs the
Merrill Lynch Recordkeeping Service Agreement. If the plan does not meet either
of these limits, Class A shares are not available.

For participating retirement plans investing in Class B shares, shares will
convert to Class A shares after eight years, or sooner if the plan attains
assets of $5 million (by means of a CDSC-free redemption/purchase at net asset
value).

DESCRIPTION OF THE FUNDS' SHARES

The Trustees of the Trust are responsible for the management and supervision of
the Funds. The Declaration of Trust permits the Trustees to issue an unlimited
number of full and fractional shares of beneficial interest of each Fund without
par value. Under the Declaration of Trust, the Trustees have the authority to
create and classify shares of beneficial interest in separate series and in one
or more classes, without further action by shareholders. As of the date of this
Statement of Additional Information, the Trustees have authorized shares of
these two Funds and one other series and the issuance of two classes of shares
of Government Income Fund, designated as Class A and Class B and three classes
of shares of High Yield Bond Fund, designated as Class A, Class B and Class C.
Additional series may be added in the future.

The shares of each class of the Funds represent an equal proportionate interest
in the aggregate net assets attributable to the classes of the Fund. Holders of
each Class of shares have certain exclusive voting rights on matters relating to
their respective distribution plans. The different classes of a Fund may bear
different expenses relating to the cost of holding shareholder meetings
necessitated by the exclusive voting rights of any class of shares.

Dividends paid by the Funds, if any, with respect to each class of shares will
be calculated in the same manner, at the same time and on the same day and will
be in the same amount, except for differences resulting from the facts that (i)
the distribution and service fees relating to each class will be borne
exclusively by that class, (ii) Class B and Class C shares will pay higher
distribution and service fees than Class A shares and (iii) each Class of shares
will bear any class expenses properly allocable to that class of shares, subject
to the conditions the Internal Revenue Service imposes with respect to the
multiple-class structures. Similarly, the net asset value per share may vary
depending on which class of shares are purchased. No interest will be paid on
uncashed dividend or redemption checks.

In the event of liquidation, shareholders of each class are entitled to share
pro rata in the net assets of the Fund available for distribution to these
shareholders. Shares entitle their holders to one vote per share, are freely
transferable and have no preemptive, subscription or conversion rights. When
issued, shares are fully paid and non-assessable, except as set forth below.

Unless otherwise required by the Investment Company Act or the Declaration of
Trust, the Fund has no intention of holding annual meetings of shareholders.
Fund shareholders may remove a Trustee by the affirmative vote of at least
two-thirds of the Trust's outstanding shares and the Trustees shall promptly
call a meeting for such purpose when requested to do so in writing by the record
holders of not less than 10% of the outstanding shares of the Trust.
Shareholders may, under certain circumstances, communicate with other
shareholders in connection with requesting a special meeting of shareholders.
However, at any time that less than in a majority of the Trustees holding 


                                       49
<PAGE>

office were elected by the shareholders, the Trustees will call a special
meeting of shareholders for the purpose of electing Trustees.

Under Massachusetts law, shareholders of a Massachusetts business trust could,
under certain circumstances, be held personally liable for acts or obligations
of the trust. However, the Trust's Declaration of Trust contains an express
disclaimer of shareholder liability for acts, obligations and affairs of the
Trust. The Declaration of Trust also provides for indemnification out of the
Trust's assets for all losses and expenses of any shareholder held personally
liable by reason of being or having been a shareholder. The Declaration of Trust
also provides that no series of the Trust shall be liable for the liabilities of
any other series. Furthermore, no fund included in the Prospectus shall be
liable for the liabilities of any other John Hancock fund. Liability is
therefore limited to circumstances in which the Trust itself would be unable to
meet its obligations, and the possibility of this occurrence is remote.


The Fund reserves the right to reject any application which conflicts with the
Fund's internal policies or the policies of any regulatory authority. John
Hancock Funds does not accept starter or credit card checks. All checks returned
by the post office as undeliverable will be reinvested at net asset value in the
fund or funds from which a redemption was made or dividend paid. Use of
information provided on the account application may be used by the Fund to
verify the accuracy of the information or for background or financial history
purposes. A joint account will be administered as a joint tenancy with right of
survivorship, unless the joint owners notify Signature Services of a different
intent. A shareholder's account is governed by the laws of The Commonwealth of
Massachusetts.


TAX STATUS

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

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

Distributions from a Fund's current or accumulated earnings and profits ("E&P")
will be taxable under the Code for investors who are subject to tax. If these
distributions are paid from the Fund's "investment company taxable income," they
will be taxable as ordinary income; and if they are paid from the Fund's "net
capital gain," they will be taxable as capital gain. (Net capital gain is the
excess (if any) of net long-term capital gain over net short-term capital loss,
and investment company taxable income is all taxable income and capital gains,
other than those gains and losses included in computing net capital gain, after
reduction by deductible expenses). As a result of federal tax legislation
enacted on August 5, 1997 (the "Act"), gain recognized after May 6, 1997 from
the sale of a capital asset is taxable to individual (noncorporate) investors at
different maximum federal income tax rates, depending generally upon the tax
holding period for the asset, 


                                       50
<PAGE>

the federal income tax bracket of the taxpayer, and the dates the asset was
acquired and/ or sold. The Treasury Department has issued guidance under the Act
that enables the Fund to pass through to its shareholders the benefits of the
capital gains rates enacted in the Act. Shareholders should consult their own
tax advisers on the correct application of these new rules in their particular
circumstances. Some distributions may be paid to shareholders as if they had
been received on December 31 of the previous year. The tax treatment described
above will apply without regard to whether distributions are received in cash or
reinvested in additional shares of the Fund.

Distributions, if any, in excess of E&P will constitute a return of capital
under the Code, which will first reduce an investor's federal tax basis in Fund
shares and then, to the extent such basis is exceeded, will generally give rise
to capital gains. Shareholders who have chosen automatic reinvestment of their
distributions will have a federal tax basis in each share received pursuant to
such a reinvestment equal to the amount of cash they would have received had
they elected to receive the distribution in cash, divided by the number of
shares received in the reinvestment.

Foreign exchange gains and losses realized by High Yield Bond Fund in connection
with certain transactions involving foreign currency-denominated debt
securities, certain foreign currency futures and options, foreign currency
forward contracts, foreign currencies, or payables or receivables denominated in
a foreign currency are subject to Section 988 of the Code, which generally
causes such gains and losses to be treated as ordinary income and losses and may
affect the amount, timing and character of distributions to shareholders.
Transactions in foreign currencies that are not directly related to a Fund's
investment in stock or securities, possibly including speculative currency
positions or currency derivatives not used for hedging purposes, may increase
the amount of gain it is deemed to recognize from the sale of certain
investments or derivatives held for less than three months, which gain is
limited under the Code to less than 30% of gross income for each taxable year,
and could under future Treasury regulations produce income not among the types
of "qualifying income" from which the Fund must derive at least 90% of its gross
income for each taxable year. If the net foreign exchange loss for a year
treated as ordinary loss under Section 988 were to exceed a Fund's investment
company taxable income computed without regard to such loss but after
considering the post-October loss regulations the resulting overall ordinary
loss for such year would not be deductible by the Fund or its shareholders in
future years.

Government Income Fund and High Yield Bond Fund may be subject to withholding
and other taxes imposed by foreign countries with respect to their investments
in foreign securities. Some tax conventions between certain countries and the
U.S. may reduce or eliminate such taxes. Investors may be entitled to claim U.S.
foreign tax credits or deductions with respect to such taxes, subject to certain
provisions and limitations contained in the Code, if the Fund so elects. If more
than 50% of the value of a Fund's total assets at the close of any taxable year
consists of stock or securities of foreign corporations, the Fund may file an
election with the Internal Revenue Service pursuant to which shareholders of the
Fund will be required to (i) include in ordinary gross income (in addition to
taxable dividends and distributions actually received) their pro rata shares of
qualified foreign taxes paid by the Fund even though not actually received by
them, and (ii) treat such respective pro rata portions as qualified foreign
taxes paid by them. The Funds probably will not satisfy this 50% requirement.

If a Fund makes this election, shareholders may then deduct such pro rata
portions of qualified foreign taxes in computing their taxable incomes, or,
alternatively, use them as foreign tax credits, subject to applicable
limitations, against their U.S. Federal income taxes. Shareholders who do not
itemize deductions for Federal income tax purposes will not, however, be able to
deduct their pro rata portion of qualified foreign taxes paid by the Fund,
although such shareholders will be required 


                                       51
<PAGE>

to include their share of such taxes in gross income. Shareholders who claim a
foreign tax credit for such foreign taxes may be required to treat a portion of
dividends received from the Fund as a separate category of income for purposes
of computing the limitations on the foreign tax credit. Tax-exempt shareholders
will ordinarily not benefit from this election. Each year (if any) that a Fund
files the election described above, its shareholders will be notified of the
amount of (i) each shareholder's pro rata share of qualified foreign taxes paid
by the Fund and (ii) the portion of Fund dividends which represents income from
each foreign country. A Fund that cannot or does not make this election may
deduct such taxes in determining the amount it has available for distribution to
shareholders, and shareholders will not, in this event, include these foreign
taxes in their income, nor will they be entitled to any tax deductions or
credits with respect to such taxes.

High Yield Bond Fund is permitted to acquire stock in foreign corporations. If
this Fund invests in stock (including an option to acquire stock such as is
inherent in a convertible bond) of certain foreign corporations that receive at
least 75% of their annual gross income from passive sources (such as interest,
dividends, certain rents and royalties or capital gain) or hold at least 50% of
their assets in investments producing such passive income ("passive foreign
investment companies"), the Fund could be subject to federal income tax and
additional interest charges on "excess distributions" received from such
companies or gain from the sale of stock in such companies, even if all income
or gain actually received by the Fund is timely distributed to its shareholders.
The Fund would not be able to pass through to its shareholders any credit or
deduction for such a tax. An election may be available to ameliorate these
adverse tax consequences, but any such election could require the Fund to
recognize taxable income or gain without the concurrent receipt of cash. Those
investments could also result in the treatment of associated capital gains as
ordinary income. The Fund may limit and/or manage its holdings in passive
foreign investment companies to minimize its tax liability or maximize its
return from these investments.

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

Upon a redemption or other disposition of shares of a Fund (including by
exercise of the exchange privilege) in a transaction that is treated as a sale
for tax purposes, a shareholder may realize a taxable gain or loss depending
upon the amount of the proceeds and the investor's basis in his shares. Any gain
or loss will be treated as capital gain or loss if the shares are capital assets
in the shareholder's hands. A sales charge paid in purchasing Class A shares of
a Fund cannot be taken into account for purposes of determining gain or loss on
the redemption or exchange of such shares within 90 days after their purchase to
the extent shares of the Fund or another John Hancock fund are subsequently
acquired without payment of a sales charge pursuant to the reinvestment or
exchange privilege. Such disregarded load will result in an increase in the
shareholder's tax basis in the shares subsequently acquired. Also, any loss
realized on a redemption or exchange may be disallowed to the extent the shares
disposed of are replaced with other shares of the same Fund within a period of
61 days beginning 30 days before and ending 30 days after the shares are
disposed of, such as pursuant to automatic dividend reinvestments. In such a
case, the basis of the shares acquired will be adjusted to reflect the
disallowed loss. Any loss realized upon the 


                                       52
<PAGE>

redemption of shares with a tax holding period of six months or less will be
treated as a long-term capital loss to the extent of any amounts treated as
distributions of Shareholders should consult their own tax advisers regarding
their particular circumstances to determine whether a disposition of Fund shares
is properly treated as a sale for tax purposes, as is assumed in the foregoing
discussion. Also, future Treasury Department guidance issued to implement the
Act may contain additional rules for determining the tax treatment of sales of
Fund shares held for various periods, including the treatment of losses on the
sales of shares held for six months or less that are recharacterized as
long-term capital losses, as described above.

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

For Federal income tax purposes, each Fund is generally permitted to carry
forward a net capital loss in any year to offset its own net capital gains, if
any, during the eight years following the year of the loss. To the extent
subsequent net capital gains are offset by such losses, they would not result in
Federal income tax liability to the applicable Fund and, as noted above, would
not be distributed as such to shareholders. As of May 31, 1997, High Yield Bond
Fund had capital loss carryforwards of $4,858,582 which expires in 2003, and
Government Income Fund had capital loss carryforwards of $20,815,945 of which
$15,347,195 expires in 2002, $1,419,401 expires in 2003 and $1,964,217 expires
in 2004 and $2,085,132 expires in 2005.

A Fund is required to accrue income on any debt securities that have more than a
de minimis amount of original issue discount (or debt securities acquired at a
market discount, if the Fund elects to include market discount in income
currently) prior to the receipt of the corresponding cash payments. The mark to
market or constructive sales rules applicable to certain options, futures and
forward contracts may also require the Fund to recognize income or gain without
a concurrent receipt of cash. However, the Fund must distribute to shareholders
for each taxable year substantially all of its net income and net capital gains,
including such income or gain, to qualify as a regulated investment company and
avoid liability for any federal income or excise tax. Therefore, the Fund may
have to dispose of its portfolio securities under disadvantageous circumstances
to generate cash, or borrow cash, to satisfy these distribution requirements.

A state income (and possibly local income and/or intangible property) tax
exemption is generally available to the extent (if any) a Fund's distributions
are derived from interest on (or, in the case of intangible property taxes, the
value of its assets is attributable to) certain U.S. Government obligations,
provided in some states that certain thresholds for holdings of such obligations
and/or reporting requirements are satisfied. The Funds will not seek to satisfy
any threshold or reporting 


                                       53
<PAGE>

requirements that may apply in particular taxing jurisdictions, although either
Fund may in its sole discretion provide relevant information to shareholders.

Each Fund will be required to report to the Internal Revenue Service (the "IRS")
all taxable distributions to shareholders, as well as gross proceeds from the
redemption or exchange of Fund shares, except in the case of certain exempt
recipients, i.e., corporations and certain other investors distributions to
which are exempt from the information reporting provisions of the Code. Under
the backup withholding provisions of Code Section 3406 and applicable Treasury
regulations, all such reportable distributions and proceeds may be subject to
backup withholding of federal income tax at the rate of 31% in the case of
non-exempt shareholders who fail to furnish a Fund with their correct taxpayer
identification number and certain certifications required by the IRS or if the
IRS or a broker notifies the Fund that the number furnished by the shareholder
is incorrect or that the shareholder is subject to backup withholding as a
result of failure to report interest or dividend income. A Fund may refuse to
accept an application that does not contain any required taxpayer identification
number or certification that the number provided is correct. If the backup
withholding provisions are applicable, any such distributions and proceeds,
whether taken in cash or reinvested in shares, will be reduced by the amounts
required to be withheld. Any amounts withheld may be credited against a
shareholder's U.S. federal income tax liability. Investors should consult their
tax advisers about the applicability of the backup withholding provisions.

The Fund may be required to account for its transactions in forward rolls or
swaps, caps, floors and collars in a manner that, under certain circumstances,
may limit the extent of its participation in such transactions. Additionally,
the Fund may be required to recognize gain, but not loss, if a swap or other
transaction is treated as a constructive sale of an appreciated financial
position in the Fund's portfolio. The Fund may have to sell portfolio securities
under disadvantageous circumstances to generate cash, or borrow cash, to satisfy
these distribution requirements.

Investments in debt obligations that are at risk of or are in default present
special tax issues for the Funds. Tax rules are not entirely clear about issues
such as when the Funds may cease to accrue interest, original issue discount, or
market discount, when and to what extent deductions may be taken for bad debts
or worthless securities, how payments received on obligations in default should
be allocated between principal and income, and whether exchanges of debt
obligations in a workout context are taxable. These and other issues will be
addressed by a Fund that holds such obligations in order to reduce the risk of
distributing insufficient income to preserve its status as a regulated
investment company and seek to avoid becoming subject to Federal income or
excise tax.

Limitations imposed by the Code on regulated investment companies like the Funds
may restrict a Fund's ability to enter into options, futures, foreign currency
positions and foreign currency forward transactions.

Certain options, futures and forward foreign currency transactions undertaken by
a Fund may cause such Fund to recognize gains or losses from marking to market
even though its positions have not been sold or terminated and affect the
character as long-term or short-term (or, in the case of certain currency
forwards, options and futures, as ordinary income or loss) and timing of some
capital gains and losses realized by the Fund. Also, certain of a Fund's losses
on its transactions involving options, futures and forward foreign currency
contracts and/or offsetting or successor portfolio positions may be deferred
rather than being taken into account currently in calculating the Fund's taxable
income or gains. Certain of such transactions may also cause a Fund to dispose
of investments sooner than would otherwise have occurred. These transactions may
therefore affect the amount, timing and character of a Fund's distributions to
shareholders. The Funds will take into 


                                       54
<PAGE>

account the special tax rules (including consideration of available elections)
applicable to options, futures or forward contracts in order to seek to minimize
any potential adverse tax consequences.

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

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

Non-U.S. investors not engaged in a U.S. trade or business with which their
investment in a Fund is effectively connected will be subject to U.S. Federal
income tax treatment that is different from that described above. These
investors may be subject to nonresident alien withholding tax at the rate of 30%
(or a lower rate under an applicable tax treaty) on amounts treated as ordinary
dividends from a Fund and, unless an effective IRS Form W-8 or authorized
substitute for Form W-8 is on file, to 31% backup withholding on certain other
payments from the Fund. Non-U.S. investors should consult their tax advisers
regarding such treatment and the application of foreign taxes to an investment
in the Funds.

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

CALCULATION OF PERFORMANCE

The Fund may advertise yield, where appropriate. For the 30-day period ended
November 30, 1997, the yields of (a) High Yield Bond Fund's Class A and Class B
shares were 9.29% and 8.97%, respectively, and (b) Government Income Fund's
Class A and Class B shares were 5.39% and 4.88%, respectively. Class C shares of
High Yield Bond fund commenced operations on May 1, 1998; therefore, there is no
yield to report.

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

                     Yield = 2 ( [ ( a-b/cd ) + 1 ] ^6 - 1)


                                       55
<PAGE>

Where:

      a = dividends and interest earned during the period.

      b = net expenses accrued during the period.

      c = the average daily number of fund shares outstanding during the
          period that would be entitled to receive dividends.

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

Total Return. Average annual total return is determined separately for each
class of shares.

Set forth below are tables showing the performance on a total return basis
(i.e., with all dividends and distributions reinvested) of a hypothetical $1,000
investment in the Class A and Class B shares of Government Income Fund and High
Yield Bond Fund. Class C shares of High Yield Bond Fund commenced operations on
May 1, 1998; therefore, there is no average annual total return to report.

*     Commencement of operations.

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

                             T = ((ERV/P)^(1/n)) - 1


                                       56
<PAGE>

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

      T = average annual total return.

      n = number of years.

      ERV = ending redeemable value of a hypothetical $1,000 investment made
            at the beginning of the 1-year and life-of-fund periods.

Because each class has its own charge and fee structure, the classes have
different performance results. In the case of each class, this calculation
assumes the maximum sales charge is included in the initial investment or the
CDSC is applied at the end of the period. This calculation assumes that all
dividends and distributions are reinvested at net asset value on the
reinvestment dates during the period. The "distribution rate" is determined by
annualizing the result of dividing the declared dividends of a Fund during the
period stated by the maximum offering price or net asset value at the end of the
period. Excluding the Funds' sales charge from the distribution rate produces a
higher rate.

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

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

Performance rankings and ratings reported periodically in national financial
publications such as MONEY MAGAZINE, FORBES, BUSINESS WEEK, THE WALL STREET
JOURNAL, MICROPAL, INC., MORNINGSTAR, STANGER'S and BARRON'S, etc. will also be
utilized. A Fund's promotional and sales literature may make reference to the
Fund's "beta." Beta reflects the market-related risk of the Fund by showing how
responsive the Fund is to the market.

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

BROKERAGE ALLOCATION

Decisions concerning the purchase and sale of portfolio securities and the
allocation of brokerage commissions are made by the Adviser pursuant to
recommendations made by an investment committee of the Adviser, which consists
of officers and directors of the Adviser and affiliates and Trustees who are
interested persons of the Funds. Orders for purchases and sales of securities
are placed in a manner which, in the opinion of the Adviser, will offer the best
price and market for the execution of each such transaction. Purchases from
underwriters of portfolio securities may include a commission or commissions
paid by the issuer and transactions with dealers serving as market makers
reflect a "spread." Debt securities are generally traded on a net basis through
dealers acting for their own account as principals and not as brokers; no
brokerage commissions are payable on these transactions.

In the U.S. and in some other countries, debt securities are traded principally
in the over-the-counter market on a net basis through dealers acting for their
own account and not as brokers. In other countries, both debt and equity
securities are traded on exchanges at fixed commission rates. commissions on
foreign transactions are generally higher than the negotiated commission rates
available in the U.S. There is generally less government supervision and
regulation of foreign stock exchanges and broker-dealers than in the U.S.

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

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

Negotiated brokerage commissions of the Funds for their respective reporting
periods are as follows:


                                       58
<PAGE>

Government Income Fund - (a) $59,080 for the period from November 1, 1996 to May
31, 1997 (b) $135,622 for the fiscal year ended October 31, 1996; and (c)
$15,814 for the fiscal year ended October 31, 1995.

High Yield Bond Fund - (a) $67,481 for the period from November 1, 1996 to May
31, 1997 (b) $39,163 for the fiscal year ended October 31, 1996; and (c) $40,228
for the fiscal year ended October 31, 1995.

As permitted by Section 28(e) of the Securities Exchange Act of 1934, each Fund
may pay to a broker which provides brokerage and research services to the Fund
an amount of disclosed commission in excess of the commission which another
broker would have charged for effecting that transaction. This practice is
subject to a good faith determination by the Trustees that the price is
reasonable in light of the services provided and to policies that the Trustees
may adopt from time to time. For the period from November 1, 1996 to May 31,
1997, Government Income Fund paid $0 and High Yield Bond Fund paid $0 in
commissions to compensate brokers for research services such as industry,
economic and company reviews and evaluations of securities.

The Adviser's indirect parent, the Life Company is the indirect sole shareholder
of John Hancock Distributors, Inc., a broker-dealer ("Distributors" or
"Affiliated Broker"). Pursuant to procedures determined by the Trustees and
consistent with the above policy of obtaining best net results, the Funds may
execute portfolio transactions with or through Affiliated Brokers. For the
fiscal years ended October 31, 1995 and 1996, the Funds paid no brokerage
commission to any Affiliated Broker. For the period from November 1, 1996 to May
31, 1997, the Fund paid no brokerage commissions to any Affiliated Broker.

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

Other investment advisory clients advised by the Adviser may also invest in the
same securities as the Fund. When these clients buy or sell the same securities
at substantially the same time, the Adviser may average the transactions as to
price and allocate the amount of available investments in a manner which the
Adviser believes to be equitable to each client, including the Fund. In some
instances, this investment procedure may adversely affect the price paid or
received by the Fund or the size of the position obtainable for it. On the other
hand, to the extent permitted by law, the Advisers may aggregate securities to
be sold or purchased for the Fund with those to be sold or purchased for other
clients managed by it in order to obtain best execution.

APPENDIX A

DESCRIPTION OF BOND RATINGS AND FUND'S ASSET COMPOSITION
The ratings of Moody's Investors Service, Inc. and Standard & Poor's Ratings
Group represent their opinions as to the quality of various debt instruments
they undertake to rate. It should be emphasized that ratings are not absolute
standards of quality. Consequently, debt instruments with the same maturity,
coupon and rating may have different yields while debt instruments of the same
maturity and coupon with different ratings may have the same yield.

MOODY'S INVESTORS SERVICE, INC.

Aaa: Bonds which are rated Aaa are judged to be of the best quality. They carry
the smallest degree of investment risk and are generally referred to as "gilt
edge." Interest payments are protected by a large or by an exceptionally stable
margin and principal is secure. While the various protective elements are likely
to change, such changes as can be visualized are most unlikely to impair the
fundamentally strong position of such issues.

Aa: Bonds which are rated Aa are judged to be of high quality by all standards.
Together with the Aaa group they comprise what are generally known as high grade
bonds. They are rated lower than the best bonds because margins of protection
may not be as large as in Aaa securities or fluctuations of protective elements
may be of greater amplitude or there may be other elements present which make
the long-term risks appear somewhat larger than in Aaa securities.

A: Bonds which are rated A possess many favorable investment attributes and are
to be considered as upper medium grade obligations. Factors giving security to
principal and interest are considered adequate but elements may be present which
suggest a susceptibility to impairment at some time in the future.

Baa: Bonds which are rated Baa are considered as medium grade obligations, i.e.,
they are neither highly protected nor poorly secured. Interest payments and
principal security appear adequate for the present but certain protective
elements may be lacking or may be characteristically unreliable over any great
length of time. Such bonds lack outstanding investment characteristics and in
fact have speculative characteristics as well.

Ba: Bonds which are rated Ba are judged to have speculative elements; their
future cannot be considered as well assured. Often the protection of interest
and principal payments may be very moderate and thereby not well safeguarded
during both good and bad times over the future. Uncertainty of position
characterizes bonds in this class.

B: Bonds which are rated B generally lack the characteristics of desirable
investment. Assurance of interest and principal payments or of maintenance of
other terms of the contract over any long period of time may be small.

Caa: Bonds which are rated Caa are of poor standing. Such issues may be in
default or there may be present elements of danger with respect to principal or
interest.

Ca: Bonds which are rated Ca represented obligations which are speculative in a
high degree. Such issues are often in default or have other marked shortcomings.


                                      A-1
<PAGE>

STANDARD & POOR'S RATINGS GROUP

AAA: Debt rated AAA has the highest rating assigned by Standard & Poor's.
Capacity to pay interest and repay principal is extremely strong.

AA: Debt rated AA has a very strong capacity to pay interest and repay principal
and differs from the highest rated issues only in small degree.

A: Debt rated A has a strong capacity to pay interest and repay principal,
although it is somewhat more susceptible to the adverse effects of changes in
circumstances and economic conditions than debt in higher rated categories.

BBB: Debt rated BBB is regarded as having an adequate capacity to pay interest
and repay principal. Whereas it normally exhibits adequate protection
parameters, adverse economic conditions or changing circumstances are more
likely to lead to a weakened capacity to pay interest and repay principal for
debt in this category than in higher rated categories.

BB, B: Debt rated BB, and B is regarded, on balance, as predominantly
speculative with respect to capacity to pay interest and repay principal in
accordance with the terms of the obligation. BB indicates the lowest degree of
speculation and CC the highest degree of speculation. While such debt will
likely have some quality and protective characteristics, these are outweighed by
large uncertainties or major risk exposures to adverse conditions.

CCC: Debt rated 'CCC' has a currently identifiable vulnerability to default, and
is dependent upon favorable business, financial, and economic conditions to meet
timely payment of interest and repayment of principal. In the event of adverse
business, financial or economic conditions, it is not likely to have the
capacity to pay interest and repay principal. The 'CCC' rating category is also
used for debt subordinated to senior debt that is assigned an actual or implied
'B' or 'B-' rating.

CC: The rating 'CC' is typically applied to debt subordinated to senior debt
that is assigned an actual or implied 'CCC' rating.

FITCH INVESTORS SERVICE ("Fitch")

AAA, AA, A, BBB - Bonds rated AAA are considered to be investment grade and of
the highest quality. The obligor has an extraordinary ability to pay interest
and repay principal, which is unlikely to be affected by reasonably foreseeable
events. Bonds rated AA are considered to be investment grade and of high
quality. The obligor's ability to pay interest and repay principal, while very
strong, is somewhat less than for AAA rated securities or more subject to
possible change over the term of the issue. Bonds rated A are considered to be
investment grade and of good quality. The obligor's ability to pay interest and
repay principal is considered to be strong, but may be more vulnerable to
adverse changes in economic conditions and circumstances than bonds with higher
ratings. Bonds rated BBB are considered to be investment grade and of
satisfactory quality. The obligor's ability to pay interest and repay principal
is considered to be adequate. Adverse changes in economic conditions and
circumstances, however, are more likely to weaken this ability than bonds with
higher ratings.


                                      A-2
<PAGE>

TAX-EXEMPT NOTE RATINGS

Moody's - MIG-1 and MIG-2. Notes rated MIG-1 are judged to be of the best
quality, enjoying strong protection from established cash flow or funds for
their services or from established and broad-based access to the market for
refinancing or both. Notes rated MIG-2 are judged to be of high quality with
ample margins of protection, though not as large as MIG-1.

S&P - SP-1 and SP-2. SP-1 denotes a very strong or strong capacity to pay
principal and interest. Issues determined to possess overwhelming safety
characteristics are given a plus (+) designation (SP-1+). SP-2 denotes a
satisfactory capacity to pay principal and interest.

Fitch - FIN-1 and FIN-2. Notes assigned FIN-1 are regarded as having the
strongest degree of assurance for timely payment. A plus symbol may be used to
indicate relative standing. Notes assigned FIN-2 reflect a degree of assurance
for timely payment only slightly less in degree than the highest category.

CORPORATE AND TAX-EXEMPT COMMERCIAL PAPER RATINGS

Moody's - Commercial Paper ratings are opinions of the ability of issuers to
repay punctually promissory obligations not having an original maturity in
excess of nine months. Prime-1, indicates highest quality repayment capacity of
rated issue and Prime-2 indicates higher quality.

S&P - Commercial Paper ratings are a current assessment of the likelihood of
timely payment of debts having an original maturity of no more than 365 days.
Issues rated A have the greatest capacity for a timely payment and the
designation 1, 2 and 3 indicates the relative degree of safety. Issues rated
"A-1+" are those with an "overwhelming degree of credit protection."

Fitch - Commercial Paper ratings reflect current appraisal of the degree of
assurance of timely payment. F-1 issues are regarded as having the strongest
degree of assurance for timely payment. (+) is used to designate the relative
position of an issuer within the rating category. F-2 issues reflect an
assurance of timely payment only slightly less in degree than the strongest
issues. The symbol (LOC) may follow either category and indicates that a letter
of credit issued by a commercial bank is attached to the commercial paper note.

Other Considerations - The ratings of S&P, Moody's, and Fitch represent their
respective opinions of the quality of the municipal securities they undertake to
rate. It should be emphasized, however, that ratings are general and are not
absolute standards of quality. Consequently, municipal securities with the same
maturity, coupon and ratings may have different yields and municipal securities
of the same maturity and coupon with different ratings may have the same yield.

ORGANIZATION OF THE FUND

The Fund is a diversified open-end investment  management company organized as a
Massachusetts   business   trust   under  the  laws  of  The   Commonwealth   of
Massachusetts.  The Fund was  organized  on April 16, 1986.  The  Trustees  have
authority  to issue an  unlimited  number of shares of  beneficial  interest  of
separate series without par value.

John Hancock Advisers,  Inc. (the "Adviser") is the Fund's  investment  adviser.
The Adviser is an indirect  wholly-owned  subsidiary of John Hancock Mutual Life
Insurance Company (the "Life Company"),  a Massachusetts  life insurance company
chartered in 1862,  with national  headquarters  at John Hancock Place,  Boston,
Massachusetts.

INVESTMENT OBJECTIVE AND POLICIES

The  following  information  supplements  the  discussion  of the Fund's  goals,
strategies and risks discussed in the Prospectus. There is no assurance that the
Fund will achieve its investment objective.

The Fund's  investment  objective  is to provide as high a level of income as is
consistent  with  long-term  total  return by investing  in  securities  issued,
guaranteed or otherwise backed by the United States government,  its agencies or
instrumentalities  ("Government  Securities").  The Adviser believes that a high
current income  consistent  with long-term total return may be derived from: (i)
interest  income from  Government  Securities;  (ii) income from  premiums  from
expired put and call options on Government Securities written by the Fund; (iii)
net gains from closing purchase and sale transactions with respect to options on
Government Securities;  and (iv) net gains from sales of portfolio securities on
exercise of options or otherwise.

Since interest yields on Government  Securities and opportunities to realize net
gains from  options  transactions  may vary from time to time because of general
economic and market  conditions and many other factors,  it is anticipated  that
the Fund's share price and yield will fluctuate.

Government Securities. Under normal circumstances, the Fund will invest at least
65% of its total assets in Government Securities. The Government Securities that
may be purchased by the Fund include, but are not limited to:

U.S. Treasury Securities. The Fund may invest in U.S. Treasury securities,
including Bills (maturities of one year or less), Notes (maturities of one to
ten years), Bonds (generally maturities of greater than ten years) and other
debt securities issued by the U.S. Treasury. These instruments are direct
obligations of the U.S. Government and differ primarily in their interest rates,
the lengths of their maturities and the times of their issuance.

Securities   Issued   or   Guaranteed   by   U.S.    Government   Agencies   and
Instrumentalities.  The Fund may also invest in securities issued by agencies of
the U.S.  Government or  instrumentalities  established or sponsored by the U.S.
Government.  The  obligations,  including  those which are guaranteed by Federal
agencies or  instrumentalities,  may or may not be backed by the "full faith and
credit" of the United  States.  In the case of securities not backed by the full
faith and credit of the United  States,  the Fund must look  principally  to the
agency issuing or guaranteeing the obligation for ultimate repayment and may not
be able to assert a claim  against  the  United  States  itself in the event the
agency or instrumentality does not meet its commitments. Securities in which the

                                       2
<PAGE>

Fund may  invest  but which are not  backed by the full  faith and credit of the
United States include but are not limited to obligations of the Tennessee Valley
Authority,  the Federal Home Loan Mortgage Corporation  ("FHLMC") and the United
States  Postal  Service,  each of which has the right to borrow  from the United
States  Treasury to meet its  obligations,  and  obligations of the Federal Farm
Credit  System,  the Federal  National  Mortgage  Association  ("FNMA")  and the
Federal Home Loan Banks,  the  obligations of which may only be satisfied by the
individual credit of the issuing agency.  Obligations of the Government National
Mortgage  Association   ("GNMA"),   the  Farmers  Home  Administration  and  the
Export-Import Bank are backed by the full faith and credit of the United States.

Securities of International Bank for Reconstruction and Development

The  Fund  may  also  purchase   obligations  of  the  International   Bank  for
Reconstruction  and Development  ("World Bank"),  which, while technically not a
U.S.  Government  agency or  instrumentality,  has the right to borrow  from the
participating countries, including the United States.

The Fund may invest in Government Securities of all maturities: short-term,
intermediate-term and long-term.

The Fund may, for purposes of liquidity and flexibility,  place up to 35% of its
assets in investment-grade (equivalent to the top four bond rating categories of
a nationally recognized securities rating organization such as Standard & Poor's
Rating  Group  ("Standard  &  Poor's")  or  Moody's  Investor's  Service,   Inc.
("Moody's"))  short-term securities,  including debt securities of corporations,
certificates of deposit of domestic banks, or repurchase agreements with respect
to Government  Securities,  including repurchase  agreements that mature in more
than seven days. In the event these securities are subsequently downgraded below
such  ratings,  the Adviser will  consider  this event in its  determination  of
whether  the Fund  should  continue  to hold the  securities.  The Fund may also
invest  in  collateralized   mortgage-backed  obligations  that  are  issued  or
sponsored by a government agency. In abnormal market  conditions,  it may invest
more assets in these  securities as a defensive  tactic.  See Appendix A to this
Statement of Additional  Information for a description of the various ratings of
investment grade debt securities.

Mortgage-Related  Securities. The Fund may invest in mortgage-backed securities,
including  those  representing  an  undivided  ownership  interest  in a pool of
mortgage loans, e.g., securities of the GNMA and pass-through  securities issued
by the FHLMC and FNMA.

GNMA   Certificates.   Certificates  of  the  GNMA  ("GNMA   Certificates")  are
mortgage-backed  securities,  which evidence an undivided  interest in a pool of
mortgage  loans.  GNMA  Certificates  differ from bonds in that the principal is
paid back monthly by the borrower over the term of the loan rather than returned
in a lump sum at maturity.  GNMA  Certificates  that the Fund  purchases are the
"modified  pass-through" type. "Modified pass-through" GNMA Certificates entitle
the holder to receive a share of all interest and  principal  payments  paid and
owed on the mortgage pool, net of fees paid to the "issuer" and GNMA, regardless
of whether or not the mortgagor actually makes the payment.

GNMA Guarantee. The National Housing Act authorizes GNMA to guarantee the timely
payment of principal  and interest on  securities  backed by a pool of mortgages
insured by the  Federal  Housing  Administration  ("FHA") or the  Farmers'  Home
Administration  ("FMHA"), or guaranteed by the Veterans  Administration  ("VA").

                                       3

<PAGE>

The GNMA  guarantee is backed by the full faith and credit of the United States.
The GNMA is also  empowered to borrow  without  limit from the U.S.  Treasury if
necessary to make any payments required under its guarantee.

Life of GNMA  Certificates.  The average life of a GNMA Certificate is likely to
be  substantially  less  than  the  original  maturity  of  the  mortgage  pools
underlying the  securities.  Prepayments of principal by mortgagors and mortgage
foreclosures  will usually result in the return of the greater part of principal
investment  long before the  contractual  maturity of the mortgages in the pool.
Foreclosures  impose  no  risk  to  principal  investment  because  of the  GNMA
guarantee.  Because they represent the underlying  mortgages,  GNMA Certificates
may not be an effective means of locking in long-term  interest rates due to the
need for the Fund to reinvest scheduled and unscheduled  principal payments.  At
the time principal payments or prepayments are received by the Fund,  prevailing
interest  rates may be  higher or lower  than the  current  yield of the  Fund's
portfolio.

Statistics  published by the FHA indicate that the average life of single-family
dwelling mortgages with 25 to 30-year maturities,  the type of mortgages backing
the vast majority of GNMA  Certificates,  is  approximately  12 years.  However,
because  prepayment  rates of individual  mortgage pools vary widely,  it is not
possible to predict  accurately  the average life of a particular  issue of GNMA
Certificates.

Yield Characteristics of GNMA Certificates.  The coupon rate of interest on GNMA
Certificates  is lower  than the  interest  rate  paid on the  VA-guaranteed  or
FHA-insured  mortgages  underlying the  Certificates,  by the amount of the fees
paid to GNMA and the issuer.

The coupon rate by itself,  however,  does not  indicate the yield which will be
earned on GNMA Certificates. First, GNMA Certificates may be issued at a premium
or discount,  rather than at par, and, after  issuance,  GNMA  Certificates  may
trade in the  secondary  market at a premium or  discount.  Second,  interest is
earned monthly,  rather than  semiannually as with  traditional  bonds;  monthly
compounding  raises the effective yield earned.  Finally,  the actual yield of a
GNMA Certificate is influenced by the prepayment experience of the mortgage pool
underlying it. For example,  if the higher- yielding mortgages from the pool are
prepaid,  the  yield on the  remaining  pool  will be  reduced.  Prepayments  of
principal  by  mortgagors  (which can be made at any time  without  penalty) may
increase during periods when interest rates are falling.

FHLMC  Securities.  The FHLMC was created in 1970 through enactment of Title III
of the Emergency Home Finance Act of 1970. Its purpose is to promote development
of a nationwide secondary market in conventional residential mortgages.

The  FHLMC  issues  two  types of  mortgage  pass-through  securities,  mortgage
participation   certificates   ("PCs")  and  guaranteed  mortgage   certificates
("GMCs").  PCs resemble GNMA  Certificates in that each PC represents a pro rata
share of all interest and  principal  payments  made and owed on the  underlying
pool. The FHLMC guarantees timely payment of interest on PCs and the full return
of principal.

GMC's also represent a pro rata interest in a pool of mortgages.  However, these
instruments  pay  interest  semiannually  and  return  principal  once a year in
guaranteed minimum payments.

FNMA Securities. The FNMA was established in 1938 to create a secondary market
in mortgages insured by the FHA. 

                                       4
<PAGE>

FNMA Issued Guaranteed Mortgage Pass-through Certificates ("FNMA Certificates").
FNMA  Certificates  resemble  GNMA  Certificates  in that each FNMA  Certificate
represents a pro rata share of all interest and principal payments made and owed
on the  underlying  pool.  FNMA  guarantees  timely  payment of interest on FNMA
Certificates and the full return of principal.

Collateralized     Mortgage-Backed     Obligations    ("CMO's").     CMOs    are
fully-collateralized  bonds  which are the  general  obligations  of the  issuer
thereof, either the U.S. Government or a U.S. Government  instrumentality.  Such
bonds  generally are secured by an assignment to a trustee  (under the indenture
pursuant to which the bonds are issued) of  collateral  consisting  of a pool of
mortgages.  Payments with respect to the underlying mortgages generally are made
to the trustee  under the  indenture.  Payments of principal and interest on the
underlying  mortgages are not passed  through to the holders of the CMOs as such
(i.e. the character of payments of principal and interest is not passed through,
and  therefore  payments to holders of CMOs  attributable  to interest  paid and
principal  repaid on the  underlying  mortgages  do not  necessarily  constitute
income and return of capital,  respectively, to such holders), but such payments
are  dedicated to payment of interest on and repayment of principal of the CMOs.
CMOs often are issued in two or more classes with varying  maturities and stated
rates of interest.  Because  interest and principal  payments on the  underlying
mortgages are not passed through to holders of CMOs, CMOs of varying  maturities
may be secured by the same pool of mortgages,  the payments on which are used to
pay  interest on each class and to retire  successive  maturities  in  sequence.
Unlike other mortgage-backed  securities (discussed above), CMOs are designed to
be retired as the underlying mortgages are repaid. In the event of prepayment on
such  mortgages,  the class of CMO first to mature  generally will be paid down.
Therefore,  although in most cases the issuer of CMOs will not supply additional
collateral in the event of such prepayment,  there will be sufficient collateral
to secure CMOs that remain outstanding.

Inverse Floating Rate  Securities.  The Fund may invest in inverse floating rate
securities. It is the current intention of the Fund to invest no more than 5% of
its net assets in inverse  floating  rate  securities.  The interest  rate on an
inverse floating rate security resets in the opposite  direction from the market
rate of interest  to which the inverse  floating  rate  security is indexed.  An
inverse  floating  rate security may be considered to be leveraged to the extent
that its  interest  rate varies by a multiple of the index rate of  interest.  A
higher  degree of leverage in the inverse  floating  rate security is associated
with greater volatility in the market value of such security.

The inverse floating rate securities that the Fund may invest in include but are
not limited to, an inverse floating rate class of a government agency issued CMO
and a government agency issued yield curve note. Typically,  an inverse floating
rate class of a CMO is one of two components  created from the cash flows from a
pool of fixed rate mortgages. The other component is a floating rate security in
which the amount of interest payable varies directly with a market interest rate
index.  A yield curve note is a fixed income  security that bears  interest at a
floating rate that is reset  periodically  based on an interest rate  benchmark.
The interest  rate resets on a yield curve note in the opposite  direction  from
the interest rate benchmark.

Mortgage-backed  securities  have stated  maturities  of up to thirty years when
they are  issued,  depending  upon the length of the  mortgages  underlying  the
securities. In practice, however, unscheduled or early payments of principal and
interest on the underlying mortgages may make the securities' effective maturity
shorter than this, and the prevailing interest rates may be higher or lower than
the current yield of the Fund's  portfolio at the time the Fund  receives  these
payments for  reinvestment.  Mortgage-backed  securities may have less potential
for capital  appreciation  than  comparable  fixed-income  securities due to the
likelihood of increased  prepayments of mortgages as interest rates decline.  If
the Fund buys mortgage-backed securities at a premium, mortgage foreclosures and

                                       5

<PAGE>

prepayments  of principal by  mortgagors  (which may be made at any time without
penalty)  may result in some loss of the  Fund's  principal  investment,  to the
extent of the premium paid.

In a rising interest rate environment,  a declining  prepayment rate will extend
the average life of many mortgage-backed securities.  Extending the average life
of a mortgage-backed  security  increases the risk of depreciation due to future
increases in market interest rates.

Repurchase Agreements.  In a repurchase agreement the Fund buys a security for a
relatively short period (usually not more than 7 days) subject to the obligation
to sell it back to the issuer at a fixed time and price plus  accrued  interest.
The Fund will enter into  repurchase  agreements  only with member  banks of the
Federal Reserve System and with "primary dealers" in U.S. Government securities.
The Adviser will continuously  monitor the  creditworthiness of the parties with
whom the Fund enters into repurchase agreements.

The Fund has  established a procedure  providing that the securities  serving as
collateral  for  each  repurchase  agreement  must be  delivered  to the  Fund's
custodian  either  physically or in book-entry form and that the collateral must
be marked to market  daily to ensure  that each  repurchase  agreement  is fully
collateralized  at all times.  In the event of  bankruptcy or other default by a
seller  of  a  repurchase  agreement,   the  Fund  could  experience  delays  in
liquidating the underlying  securities during the period in which the Fund seeks
to enforce its rights thereto,  possible subnormal levels of income,  decline in
value of the  underlying  securities  or lack of access to  income  during  this
period and the expense of enforcing its rights.

Reverse Repurchase  Agreements.  The Fund may also enter into reverse repurchase
agreements  which  involve the sale of U.S.  Government  securities  held in its
portfolio to a bank with an agreement that the Fund will buy back the securities
at a fixed  future  date at a fixed  price plus an agreed  amount of  "interest"
which may be reflected in the repurchase price.  Reverse  repurchase  agreements
are  considered  to be  borrowings by the Fund.  Reverse  repurchase  agreements
involve the risk that the market value of securities  purchased by the Fund with
proceeds  of the  transaction  may  decline  below the  repurchase  price of the
securities  sold by the Fund which it is  obligated to  repurchase.  To minimize
various  risks  associated  with reverse  repurchase  agreements,  the Fund will
establish and maintain with the Fund's custodian a separate  account  consisting
of liquid  securities,  of any type or maturity,  in an amount at least equal to
the repurchase  prices of the  securities  (plus any accrued  interest  thereon)
under such agreements.  The Fund will also continue to be subject to the risk of
a decline  in the  market  value of the  securities  sold  under the  agreements
because it will reacquire those securities upon effecting their repurchase.  The
Fund will not enter into  reverse  repurchase  agreements  and other  borrowings
except from banks temporarily for  extraordinary or emergency  purposes (not for
leveraging or  investment)  and then in an aggregate  amount not in excess of 33
1/3% of the value of the Fund's total  assets  (including  the amount  borrowed)
less liabilities (not including the amount  borrowed).  The Fund will enter into
reverse  repurchase  agreements  only with  federally  insured  banks  which are
approved in advance as being  creditworthy  by the  Trustees.  Under  procedures
established by the Trustees,  the Adviser will monitor the  creditworthiness  of
the banks involved.

Restricted Securities.  The Fund may purchase securities that are not registered
("restricted  securities")  under  the  Securities  Act of  1933  ("1933  Act"),
including  commercial  paper  issued in reliance on section 4(2) of the 1933 Act
and securities offered and sold to "qualified  institutional  buyers" under Rule
144A  under the 1933  Act.  The Fund  will not  invest  more than 15% of its net
assets  in  illiquid  investments.  If  the  Trustees  determine  based  upon  a
continuing review of the trading markets for specific Section 4(2) paper or Rule
144A securities, that they are liquid, they will not be subject to the 15% limit

                                       6
<PAGE>

on illiquid  investments.  The Trustees may adopt guidelines and delegate to the
Adviser the daily  function of  determining  the  monitoring  and  liquidity  of
restricted securities.  The Trustees,  however, will retain sufficient oversight
and  be  ultimately  responsible  for  the  determinations.  The  Trustees  will
carefully monitor the Fund's  investments in these securities,  focusing on such
important  factors,  among others,  as valuation,  liquidity and availability of
information.  This  investment  practice could have the effect of increasing the
level of illiquidity in the Fund if qualified  institutional buyers become for a
time uninterested in purchasing these restricted  securities.  The Fund will not
invest more than 5% of its total assets in Rule 144A  securities  without  first
supplementing   the   prospectus   and  providing   additional   information  to
shareholders.

Options on Securities  and Securities  Indices.  The Fund may purchase and write
(sell) call and put options on any  securities  in which it may invest or on any
securities  index based on securities in which it may invest.  These options may
be  listed  on  national  domestic   securities   exchanges  or  traded  in  the
over-the-counter  market.  The Fund may write  covered put and call  options and
purchase put and call options to enhance total return,  as a substitute  for the
purchase or sale of securities,  or to protect against  declines in the value of
portfolio  securities  and against  increases  in the cost of  securities  to be
acquired.

Writing  Covered  Options.  A call  option  on  securities  written  by the Fund
obligates the Fund to sell specified securities to the holder of the option at a
specified  price if the option is  exercised  at any time before the  expiration
date.  A put  option  on  securities  written  by a Fund  obligates  the Fund to
purchase specified securities from the option holder at a specified price if the
option  is  exercised  at any  time  before  the  expiration  date.  Options  on
securities  indices  are  similar  to  options on  securities,  except  that the
exercise of securities index options requires cash settlement  payments and does
not involve the actual purchase or sale of securities.  In addition,  securities
index  options  are  designed  to  reflect  price  fluctuations  in a  group  of
securities or segment of the securities market rather than price fluctuations in
a single  security.  Writing  covered  call  options may deprive the Fund of the
opportunity  to profit from an increase in the market price of the securities in
its  portfolio.  Writing  covered  put  options  may  deprive  the  Fund  of the
opportunity  to profit from a decrease in the market price of the  securities to
be acquired for its portfolio.

All call and put options written by the Funds are covered. A written call option
or put option may be covered by (i) maintaining  cash or liquid  securities in a
segregated  account  maintained  by the Fund's  custodian  with a value at least
equal  to the  Fund's  obligation  under  the  option,  (ii)  entering  into  an
offsetting  forward  commitment  and/or (iii) purchasing an offsetting option or
any other option which,  by virtue of its exercise  price or otherwise,  reduces
the Fund's net exposure on its written option position. A written call option on
securities is typically  covered by maintaining  the securities that are subject
to the option in a  segregated  account.  The Fund may cover  call  options on a
securities  index by owning  securities  whose price  changes are expected to be
similar to those of the underlying index.

The Fund may  terminate  its  obligations  under an exchange  traded call or put
option by purchasing an option identical to the one it has written.  Obligations
under  over-the-counter  options  may be  terminated  only by  entering  into an
offsetting  transaction with the counterparty to such option. Such purchases are
referred to as "closing purchase transactions."

Purchasing   Options.   The  Fund  would  normally   purchase  call  options  in
anticipation  of an  increase,  or put  options  in  anticipation  of a decrease
("protective  puts") in the market value of  securities  of the type in which it
may  invest.  The Fund may also  sell  call  and put  options  to close  out its
purchased options.

                                       7
<PAGE>

The purchase of a call option would  entitle the Fund, in return for the premium
paid, to purchase  specified  securities at a specified  price during the option
period.  The Fund  would  ordinarily  realize a gain on the  purchase  of a call
option if, during the option period,  the value of such securities  exceeded the
sum of the exercise price, the premium paid and transaction costs; otherwise the
Fund would realize either no gain or a loss on the purchase of the call option.

The purchase of a put option would entitle the Fund, in exchange for the premium
paid,  to sell  specified  securities  at a  specified  price  during the option
period. The purchase of protective puts is designed to offset or hedge against a
decline in the market value of the Fund's portfolio securities.  Put options may
also be purchased by the Fund for the purpose of affirmatively benefiting from a
decline  in the  price of  securities  which it does  not  own.  The Fund  would
ordinarily  realize  a gain if,  during  the  option  period,  the  value of the
underlying  securities  decreased below the exercise price sufficiently to cover
the premium and  transaction  costs;  otherwise the Fund would realize either no
gain or a loss on the  purchase  of the put  option.  Gains  and  losses  on the
purchase of put options may be offset by countervailing  changes in the value of
the Fund's portfolio securities.

The Fund's options  transactions  will be subject to limitations  established by
each of the exchanges, boards of trade or other trading facilities on which such
options are traded.  These  limitations  govern the maximum number of options in
each class which may be written or  purchased  by a single  investor or group of
investors  acting in concert,  regardless  of whether the options are written or
purchased on the same or different  exchanges,  boards of trade or other trading
facilities or are held or written in one or more accounts or through one or more
brokers. Thus, the number of options which the Fund may write or purchase may be
affected by options written or purchased by other investment advisory clients of
the Adviser. An exchange, board of trade or other trading facility may order the
liquidation  of  positions  found to be in  excess of these  limits,  and it may
impose certain other sanctions.

Risks Associated with Options Transactions.  There is no assurance that a liquid
secondary  market on a domestic or foreign  options  exchange will exist for any
particular  exchange-traded  option or at any  particular  time.  If the Fund is
unable to effect a closing purchase  transaction with respect to covered options
it has written,  the Fund will not be able to sell the underlying  securities or
dispose of assets held in a segregated  account until the options  expire or are
exercised. Similarly, if the Fund is unable to effect a closing sale transaction
with respect to options it has purchased,  it would have to exercise the options
in order to  realize  any  profit  and will  incur  transaction  costs  upon the
purchase or sale of underlying securities.

Reasons for the absence of a liquid  secondary market on an exchange include the
following:  (i) there may be insufficient  trading  interest in certain options;
(ii)  restrictions  may be imposed by an  exchange  on opening  transactions  or
closing  transactions  or  both;  (iii)  trading  halts,  suspensions  or  other
restrictions  may be imposed  with  respect to  particular  classes or series of
options;   (iv)  unusual  or  unforeseen   circumstances  may  interrupt  normal
operations  on an  exchange;  (v) the  facilities  of an exchange or the Options
Clearing  Corporation may not at all times be adequate to handle current trading
volume;  or (vi) one or more  exchanges  could,  for economic or other  reasons,
decide or be compelled at some future date to discontinue the trading of options
(or a particular class or series of options). If trading were discontinued,  the
secondary  market on that exchange (or in that class or series of options) would
cease to exist.  However,  outstanding  options on that  exchange  that had been
issued  by the  Options  Clearing  Corporation  as a result  of  trades  on that
exchange would continue to be exercisable in accordance with their terms.

                                       8

<PAGE>

The Fund's  ability to terminate  over-the-counter  options is more limited than
with  exchange-traded  options  and may  involve  the risk  that  broker-dealers
participating  in such  transactions  will not fulfill  their  obligations.  The
Adviser  will  determine  the  liquidity  of  each  over-the-counter  option  in
accordance with guidelines adopted by the Trustees.

The  writing  and  purchase of options is a highly  specialized  activity  which
involves  investment  techniques and risks different from those  associated with
ordinary  portfolio  securities  transactions.  The  successful  use of  options
depends in part on the Adviser's  ability to predict  future price  fluctuations
and, for hedging transactions, the degree of correlation between the options and
securities markets.

Futures  Contracts and Options on Futures  Contracts.  To seek to increase total
return or hedge against changes in interest rates or securities prices, the Fund
may purchase and sell various kinds of futures contracts, and purchase and write
call and put options on these  futures  contracts.  The Fund may also enter into
closing  purchase and sale  transactions  with respect to any of these contracts
and options.  The futures contracts may be based on various  securities (such as
U.S.  Government  securities),   securities  indices  and  any  other  financial
instruments  and  indices.  All futures  contracts  entered into by the Fund are
traded on U.S.  exchanges  or boards of trade that are  licensed,  regulated  or
approved by the Commodity Futures Trading Commission ("CFTC").

Futures Contracts. A futures contract may generally be described as an agreement
between  two parties to buy and sell  particular  financial  instruments  for an
agreed price during a designated  month (or to deliver the final cash settlement
price,  in the case of a contract  relating to an index or otherwise not calling
for physical delivery at the end of trading in the contract).

Positions taken in the futures markets are not normally held to maturity but are
instead liquidated through offsetting  transactions which may result in a profit
or a loss.  While futures  contracts on securities will usually be liquidated in
this manner,  the Fund may instead  make,  or take,  delivery of the  underlying
securities  whenever it appears  economically  advantageous to do so. A clearing
corporation  associated with the exchange on which futures  contracts are traded
guarantees  that,  if still open,  the sale or purchase will be performed on the
settlement date.

Hedging  and Other  Strategies.  Hedging is an attempt  to  establish  with more
certainty than would otherwise be possible the effective price or rate of return
on portfolio  securities or securities  that the Fund proposes to acquire.  When
interest rates are rising or securities prices are falling, the Fund can seek to
offset a decline in the value of its current  portfolio  securities  through the
sale of futures contracts.  When interest rates are falling or securities prices
are rising, the Fund, through the purchase of futures contracts,  can attempt to
secure  better  rates or prices than might later be available in the market when
it effects anticipated purchases.

The Fund may,  for  example,  take a "short"  position in the futures  market by
selling futures  contracts in an attempt to hedge against an anticipated rise in
interest  rates or a decline in market  prices that would  adversely  affect the
value of the Fund's  portfolio  securities.  Such futures  contracts may include
contracts for the future  delivery of securities  held by the Fund or securities
with characteristics similar to those of the Fund's portfolio securities.

If, in the opinion of the Adviser,  there is a sufficient  degree of correlation
between price trends for the Fund's portfolio  securities and futures  contracts
based on other financial  instruments,  securities indices or other indices, the
Fund may also enter into such futures contracts as part of its hedging strategy.
Although under some  circumstances  prices of securities in the Fund's portfolio

                                       9

<PAGE>

may be more or less volatile than prices of such futures contracts,  the Adviser
will  attempt to  estimate  the extent of this  volatility  difference  based on
historical patterns and compensate for any differential by having the Fund enter
into a greater or lesser number of futures contracts or by attempting to achieve
only a partial  hedge  against  price  changes  affecting  the Fund's  portfolio
securities.

When a short hedging  position is successful,  any  depreciation in the value of
portfolio  securities will be substantially  offset by appreciation in the value
of the futures position.  On the other hand, any  unanticipated  appreciation in
the value of the Fund's portfolio  securities would be substantially offset by a
decline in the value of the futures position.

On other  occasions,  the Fund may take a "long" position by purchasing  futures
contracts.  This  would be done,  for  example,  when the Fund  anticipates  the
subsequent purchase of particular securities when it has the necessary cash, but
expects the prices then available in the applicable  market to be less favorable
than prices that are currently  available.  The Fund may also  purchase  futures
contracts  as  a  substitute  for  transactions  in  securities,  to  alter  the
investment  characteristics  of portfolio  securities or to gain or increase its
exposure to a particular securities market.

Options on Futures Contracts. The Fund may purchase and write options on futures
for the same purposes as its transactions in futures contracts.  The purchase of
put and call options on futures  contracts will give the Fund the right (but not
the obligation) for a specified price to sell or to purchase,  respectively, the
underlying  futures  contract  at any time  during  the  option  period.  As the
purchaser  of an option on a futures  contract,  the Fund obtains the benefit of
the futures position if prices move in a favorable direction but limits its risk
of loss in the event of an unfavorable price movement to the loss of the premium
and transaction costs.

The writing of a call option on a futures contract generates a premium which may
partially offset a decline in the value of the Fund's assets.  By writing a call
option, the Fund becomes  obligated,  in exchange for the premium (upon exercise
of the option) to sell a futures contract if the option is exercised,  which may
have a value higher than the exercise  price.  Conversely,  the writing of a put
option on a futures  contract  generates a premium which may partially offset an
increase in the price of securities that the Fund intends to purchase.  However,
the Fund becomes  obligated  (upon exercise of the option) to purchase a futures
contract  if the  option is  exercised,  which may have a value  lower  than the
exercise  price.  The loss incurred by the Fund in writing options on futures is
potentially unlimited and may exceed the amount of the premium received.

The  holder or writer of an option  on a  futures  contract  may  terminate  its
position by selling or purchasing an offsetting option of the same series. There
is no guarantee  that such  closing  transactions  can be  effected.  The Fund's
ability to establish  and close out positions on such options will be subject to
the development and maintenance of a liquid market.

Other  Considerations.  The Fund will  engage in  futures  and  related  options
transactions  either for bona fide hedging purposes or to seek to increase total
return as  permitted by the CFTC.  To the extent that the Fund is using  futures
and related  options for hedging  purposes,  futures  contracts  will be sold to
protect  against a  decline  in the  price of  securities  that the Fund owns or
futures  contracts  will be purchased to protect the Fund against an increase in
the price of securities it intends to purchase. The Fund will determine that the
price  fluctuations  in the futures  contracts  and options on futures  used for
hedging purposes are substantially  related to price  fluctuations in securities
held by the Fund or securities or instruments  which it expects to purchase.  As
evidence  of its hedging  intent,  the Fund  expects  that on 75% or more of the

                                       10
<PAGE>

occasions on which it takes a long  futures or option  position  (involving  the
purchase of futures contracts),  the Fund will have purchased, or will be in the
process of  purchasing,  equivalent  amounts of related  securities  in the cash
market at the time when the futures or option  position is closed out.  However,
in particular cases, when it is economically advantageous for the Fund to do so,
a long futures  position may be terminated  or an option may expire  without the
corresponding purchase of securities or other assets.

To the  extent  that the Fund  engages  in  nonhedging  transactions  in futures
contracts  and options on futures,  the  aggregate  initial  margin and premiums
required to establish these  nonhedging  positions will not exceed 5% of the net
asset  value of the Fund's  portfolio,  after  taking  into  account  unrealized
profits and losses on any such  positions and excluding the amount by which such
options were in-the-money at the time of purchase.

Transactions  in futures  contracts  and  options on futures  involve  brokerage
costs,  require  margin  deposits  and,  in the case of  contracts  and  options
obligating the Fund to purchase  securities,  require the Fund to establish with
the custodian a segregated account consisting of cash or liquid securities in an
amount equal to the underlying value of such contracts and options.

While  transactions  in futures  contracts  and  options  on futures  may reduce
certain risks,  these  transactions  themselves  entail certain other risks. For
example, unanticipated changes in interest rates or securities prices may result
in a poorer overall performance for the Fund than if it had not entered into any
futures contracts or options transactions.

Perfect correlation between the Fund's futures positions and portfolio positions
will be  impossible  to  achieve.  There are no  futures  contracts  based  upon
individual  securities,  except  certain U.S.  Government  securities.  The only
futures contracts available to hedge the Fund's portfolio are various futures on
U.S. Government  securities,  securities indices and foreign currencies.  In the
event of an  imperfect  correlation  between a futures  position and a portfolio
position  which is intended to be protected,  the desired  protection may not be
obtained and the Fund may be exposed to risk of loss.

Some futures  contracts or options on futures may become  illiquid under adverse
market conditions. In addition, during periods of market volatility, a commodity
exchange may suspend or limit trading in a futures  contract or related  option,
which may make the  instrument  temporarily  illiquid  and  difficult  to price.
Commodity exchanges may also establish daily limits on the amount that the price
of a  futures  contract  or  related  option  can vary from the  previous  day's
settlement  price.  Once the daily limit is reached,  no trades may be made that
day at a price  beyond the limit.  This may  prevent  the Fund from  closing out
positions and limiting its losses.

Forward Commitment and When-Issued Securities.  The Fund may purchase securities
on  a  when-issued  or  forward  commitment  basis.  "When-  issued"  refers  to
securities  whose terms are available and for which a market  exists,  but which
have not been  issued.  The Fund will engage in  when-issued  transactions  with
respect to  securities  purchased  for its  portfolio in order to obtain what is
considered to be an advantageous price and yield at the time of the transaction.
For when-issued transactions,  no payment is made until delivery is due, often a
month or more after the purchase. In a forward commitment transaction,  the Fund
contracts  to  purchase  securities  for a fixed  price at a future  date beyond
customary settlement time.

When the Fund engages in forward  commitment and  when-issued  transactions,  it
relies on the seller to consummate the transaction. The failure of the issuer or
seller to  consummate  the  transaction  may  result in the  Fund's  losing  the
opportunity  to obtain a price  and yield  considered  to be  advantageous.  The

                                       11
<PAGE>

purchase of  securities on a when-issued  or forward  commitment  basis may also
involve a risk of loss if the value of the  security  to be  purchased  declines
prior to the settlement date.

On the date the Fund  enters  into an  agreement  to  purchase  securities  on a
when-issued or forward  commitment  basis, the Fund will segregate in a separate
account cash or liquid  securities,  of any type or maturity,  equal in value to
the  Fund's  commitment.  These  assets  will be  valued  daily at  market,  and
additional  cash or securities  will be segregated in a separate  account to the
extent  that the total  value of the assets in the  account  declines  below the
amount of the when-issued  commitments.  Alternatively,  the Fund may enter into
offsetting contracts for the forward sale of other securities that it owns.

Mortgage  "Dollar Roll"  Transactions.  The Fund may enter into mortgage "dollar
roll" transactions with selected banks and broker-dealers  pursuant to which the
Fund sells mortgage-backed securities and simultaneously contracts to repurchase
substantially similar (same type, coupon and maturity) securities on a specified
future date.  The Fund will only enter into covered rolls. A "covered roll" is a
specific type of dollar roll for which there is an offsetting cash position or a
cash  equivalent  security  position  which  matures  on or before  the  forward
settlement date of the dollar roll transaction. Covered rolls are not treated as
a borrowing or other senior  security and will be excluded from the  calculation
of the Fund's borrowing and other senior securities. For financial reporting and
tax  purposes,   the  Fund  treats   mortgage   dollar  rolls  as  two  separate
transactions;   one  involving  the  purchase  of  a  security  and  a  separate
transaction  involving a sale. The Fund does not currently  intend to enter into
mortgage dollar roll transactions that are accounted for as a financing.

Asset-Backed  Securities.  The  Fund may  invest  a  portion  of its  assets  in
asset-backed securities. Asset-backed securities are often subject to more rapid
repayment  than their  stated  maturity  date would  indicate as a result of the
pass-through of prepayments of principal on the underlying loans. During periods
of  declining  interest  rates,  prepayment  of  loans  underlying  asset-backed
securities  can be expected to  accelerate.  Accordingly,  the Fund's ability to
maintain  positions in these  securities  will be affected by  reductions in the
principal amount of such securities resulting from prepayments,  and its ability
to  reinvest  the  returns  of  principal  at  comparable  yields is  subject to
generally prevailing interest rates at that time.

Credit  card  receivables  are  generally  unsecured  and  the  debtors  on such
receivables  are  entitled  to the  protection  of a number of state and federal
consumer  credit  laws,  many of which  give such  debtors  the right to set-off
certain  amounts  owed on the credit  cards,  thereby  reducing the balance due.
Automobile  receivables  generally are secured,  but by automobiles  rather than
residential  real property.  Most issuers of automobile  receivables  permit the
loan services to retain possession of the underlying obligations. If the service
were to sell  these  obligations  to  another  party,  there is a risk  that the
purchaser  would  acquire an  interest  superior  to that of the  holders of the
asset-backed  securities.  In addition,  because of the large number of vehicles
involved in a typical issuance and technical  requirements under state laws, the
trustee  for the  holders of the  automobile  receivables  may not have a proper
security  interest  in  the  underlying  automobiles.  Therefore,  there  is the
possibility that, in some cases, recoveries on repossessed collateral may not be
available to support payments on these securities.

Participation  Interests.  Participation  interests,  which may take the form of
interests in, or assignments of certain loans,  are acquired from banks who have
made these loans or are members of a lending  syndicate.  The Fund's investments
in  participation  interests may be subject to its 15% limitation on investments
in illiquid securities.

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

Swaps,  Caps,  Floors  and  Collars.  As one way of  managing  its  exposure  to
different  types of  investments,  the Fund may enter into  interest rate swaps,
currency swaps,  and other types of swap  agreements  such as caps,  collars and
floors.  In a typical  interest  rate  swap,  one party  agrees to make  regular
payments equal to a floating interest rate times a "notional  principal amount,"
in return  for  payments  equal to a fixed  rate  times the same  amount,  for a
specified period of time. If a swap agreement  provides for payment in different
currencies, the parties might agree to exchange the notional principal amount as
well.  Swaps may also depend on other  prices or rates,  such as the value of an
index or mortgage prepayment rates.

In a typical cap or floor  agreement,  one party  agrees to make  payments  only
under  specified  circumstances,  usually in return for  payment of a fee by the
other party. For example, the buyer of an interest rate cap obtains the right to
receive  payments  to the  extent  that a  specified  interest  rate  exceeds an
agreed-upon  level,  while the seller of an interest  rate floor is obligated to
make  payments  to the extent  that a  specified  interest  rate falls  below an
agreed-upon level. An interest rate collar combines elements of buying a cap and
selling a floor.

Swap agreements will tend to shift the Fund's investment  exposure from one type
of investment to another.  For example,  if the Fund agreed to exchange payments
in dollars for payments in a foreign currency,  the swap agreement would tend to
decrease the Fund's exposure to U.S. interest rates and increase its exposure to
foreign  currency and interest rates.  Caps and floors have an effect similar to
buying or writing  options.  Depending on how they are used, swap agreements may
increase or decrease  the overall  volatility  of a Fund's  investments  and its
share price and yield.

Swap agreements are sophisticated  hedging  instruments that typically involve a
small  investment  of cash  relative to the  magnitude  of risks  assumed.  As a
result,  swaps can be highly volatile and may have a considerable  impact on the
Fund's  performance.  Swap  agreements  are  subject  to  risks  related  to the
counterpart's  ability to perform, and may decline in value if the counterpart's
credit worthiness deteriorates.  The Fund may also suffer losses if it is unable
to  terminate  outstanding  swap  agreements  or  reduce  its  exposure  through
offsetting transactions. The Fund will maintain in a segregated account with its
custodian,  cash or liquid,  high grade debt securities equal to the net amount,
if any,  of the  excess of the  Fund's  obligations  over its  entitlement  with
respect to swap, cap, collar or floor transactions.

Pay-In-Kind,  Delayed and Zero Coupon Bonds. The Fund may invest in pay-in-kind,
delayed and zero coupon bonds.  These are  securities  issued at a discount from
their face  value  because  interest  payments  are  typically  postponed  until
maturity.  The amount of the discount rate varies depending on factors including
the time remaining until  maturity,  prevailing  interest rates,  the security's

                                       13

<PAGE>

liquidity and the issuer's  credit quality.  These  securities also may take the
form of debt  securities that have been stripped of their interest  payments.  A
portion of the discount with respect to stripped tax-exempt  securities or their
coupons  may be  taxable.  The market  prices in  pay-in-kind,  delayed and zero
coupon  bonds   generally   are  more   volatile   than  the  market  prices  of
interest-bearing  securities  and are likely to  respond to a greater  degree to
changes  in  interest  rates than  interest-bearing  securities  having  similar
maturities and credit quality.  The Fund's  investments in pay-in-kind,  delayed
and zero  coupon  bonds may require  the Fund to sell  certain of its  portfolio
securities to generate  sufficient cash to satisfy  certain income  distribution
requirements. See "Tax Status."

The composition and weighted  average maturity of the Fund's portfolio will vary
from time to time,  based upon the  determination  of the Adviser of how best to
further the Fund's investment objective.

Lending  of  Securities.  The Fund may lend  portfolio  securities  to  brokers,
dealers,  and financial  institutions if the loan is  collateralized  by cash or
Government Securities according to applicable regulatory requirements.  The Fund
may reinvest  any cash  collateral  in  short-term  securities  and money market
funds.  When the  Fund  lends  portfolio  securities,  there is a risk  that the
borrower may fail to return the  securities  involved in the  transaction.  As a
result, the Fund may incur a loss or, in the event of the borrower's bankruptcy,
the Fund may be delayed in or prevented from liquidating the collateral. It is a
fundamental  policy of the Fund not to lend portfolio  securities having a total
value exceeding 30% of its total assets.

Trading of Securities.  The Fund may trade those Government Securities which are
not covering outstanding options positions and are not on loan to broker-dealers
if  the  Fund's  Adviser  believes  that  there  are  opportunities  to  exploit
differentials in prices and yields or fluctuations in interest rates, consistent
with its  investment  objective.  Such trading may have the effect of increasing
the Fund's portfolio turnover rate.
See "Portfolio Turnover".

Portfolio  Turnover.  If the Fund writes a number of call options and the market
prices of the underlying securities  appreciate,  or if the Fund writes a number
of put options and the market prices of the  underlying  securities  depreciate,
there may be a substantial  turnover of the  portfolio.  While the Fund will pay
commissions in connection with its options  transactions,  Government Securities
are generally traded on a "net" basis with dealers acting as principal for their
own accounts  without a stated  commission.  A high rate of  portfolio  turnover
(100% or greater)  involves  correspondingly  greater  brokerage  expenses.  The
Fund's  portfolio  turnover  rate is set  forth in the table  under the  caption
"Financial Highlights" in the Prospectus.

Fundamental Investment Restrictions.  The following investment restrictions will
not be changed  without the  approval  of a majority  of the Fund's  outstanding

         not considered to be the issuance of senior securities for purposes of
         this restriction.

         such purchase more than 5% of the value of the Fund's total assets
         would be invested in such issuer or the Fund would own or hold more
         than 10% of the outstanding voting securities of such issuer; provided,
         however, that up to 25% of the value of the Fund's total assets may be
         invested without regard to these limitations.

         contracts and/or purchase or sell such futures contracts and options
         thereon as described in the Prospectus.

9.       Making Loans. Make loans, except that the Fund may purchase or hold
         debt instruments and may enter into repurchase agreements (subject to
         Restriction 12) in accordance with its investment objective and
         policies and make loans of portfolio securities provided that as a

         current value, would be so loaned.

10.      Industry Concentration. Purchase any securities which would cause more

         such purchase to be invested in the securities of one or more issuers

                                       15
<PAGE>

         having their principal business activities in the same industry,
         provided that there is no limitation with respect to investments in
         obligations issued or guaranteed by the U.S. Government, its agencies
         or instrumentalities.

         Nonfundamental Investment Restrictions. The following restrictions are
         designated as nonfundamental and may be changed by the Trustees without
         shareholder approval.

         The Fund may not:

11.      Options Transactions. Write, purchase, or sell puts, calls or
         combinations thereof except that the Fund may write, purchase or sell
         puts and calls on securities as described in the Prospectus and this
         Statement of Additional Information.

         12. Invest more than 15% of its net assets in illiquid securities.

13.      Acquisition for Control Purposes. Purchase securities of any issuer for
         the purpose of exercising control or management, except in connection
         with a merger, consolidation, acquisition or reorganization.

14.      Joint Trading Accounts. Participate on a joint or joint and several
         basis in any trading account in securities (except for a joint account
         with other funds managed by the Adviser for repurchase agreements
         permitted by the Securities and Exchange Commission pursuant to an
         exemptive order).

15.      Securities of Other Investment Companies. Purchase a security if, as a
         result, (i) more than 10% of the Fund's total assets would be invested
         in the securities of other investment companies, (ii) the Fund would
         hold more than 3% of the total outstanding voting securities of any one
         investment company, or (iii) more than 5% of the Fund's total assets
         would be invested in the securities of any one investment company.
         These limitations do not apply to (a) the investment of cash
         collateral, received by the Fund in connection with lending the Fund's
         portfolio securities, in the securities of open-end investment
         companies or (b) the purchase of shares of any investment company in
         connection with a merger, consolidation, reorganization or purchase of
         substantially all of the assets of another investment company. Subject
         to the above percentage limitations, the Fund may, in connection with
         the John Hancock Group of Funds Deferred Compensation Plan for
         Independent Trustees/Directors, purchase securities of other investment
         companies within the John Hancock Group of Funds.

If a percentage  restriction  is adhered to at the time of  investment,  a later
increase  or  decrease  in  percentage  resulting  from a change  in  values  of
portfolio securities or amounts of net assets will not be considered a violation
of any of the  foregoing  restrictions  (with the  exception  of  Restriction  2
permitting the Fund to borrow up to 33 1/3% of the value of its total assets).

THOSE RESPONSIBLE FOR MANAGEMENT

The business of the Fund is managed by its  Trustees who elect  officers who are
responsible for the day-to-day  operations of the Fund and who execute  policies
formulated by the Trustees. Several of the officers and Trustees of the Fund are
also  officers and  directors  of the Adviser or officers  and  Directors of the
Fund's principal distributor, John Hancock Funds, Inc. ("John Hancock Funds").

of  preparing,   printing  and  mailing  all  shareholders'  reports,   notices,
prospectuses,  proxy  statements  and reports to regulatory  agencies;  expenses
relating to the issuance,  registration and qualification of shares;  government
fees;  interest  charges;  expenses of furnishing to shareholders  their account
statements;  taxes;  expenses of redeeming shares;  brokerage and other expenses
connected  with the  execution of portfolio  securities  transactions;  expenses
pursuant to the Fund's plan of  distribution;  fees and  expenses of  custodians
including  those for keeping  books and accounts and  calculating  the net asset
value of shares;  fees and expenses of transfer  agents and dividend  disbursing
agents;  legal,  accounting,  financial,  management,  tax and auditing fees and
expenses  of the  Fund  (including  an  allocable  portion  of the  cost  of the
Adviser's  employees  rendering such services to the Fund); the compensation and
expenses  of  Trustees  who are not  otherwise  affiliated  with the Trust,  the
Adviser or any of their  affiliates;  expenses of  Trustees'  and  shareholders'
meetings;   trade  association   memberships;   insurance   premiums;   and  any
extraordinary expenses.

As compensation for its services under the Advisory Agreement, the Fund pays the
Adviser monthly a fee based upon the following annual rates: 0.50% of the Fund's
first $500 million of average  daily net assets,  and 0.45% of average daily net
assets in excess of that amount.

From time to time, the Adviser may reduce its fee or make other  arrangements to
limit the Fund's expenses to a specified percentage of average daily net assets.
The Adviser  retains the right to reimpose a fee and recover any other  payments
to the extent that, at the end of any fiscal year,  the Fund's  annual  expenses
fall below this limit.

Securities  held by the  Fund may  also be held by  other  funds  or  investment
advisory  clients for which the  Adviser or its  affiliates  provide  investment
advice.   Because  of  different  investment  objectives  or  other  factors,  a
particular  security  may be bought for one or more funds or clients when one or
more are selling the same  security.  If  opportunities  for purchase or sale of
securities  by the  Adviser for the Fund or for other funds or clients for which
the Adviser renders  investment  advice arise for  consideration at or about the

                                       25
<PAGE>

same time, transactions in such securities will be made insofar as feasible, for
the respective  funds or clients in a manner deemed equitable to all of them. To
the extent that transactions on behalf of more than one client of the Adviser or
its  affiliates may increase the demand for  securities  being  purchased or the
supply of securities being sold, there may be an adverse effect on price.

Pursuant to the Advisory Agreement, the Adviser is not liable to the Fund or its
shareholders  for any  error  of  judgment  or  mistake  of law or for any  loss
suffered  by the Fund in  connection  with the  matters  to which  the  Advisory
Agreement relates,  except a loss resulting from willful misfeasance,  bad faith
or gross  negligence on the part of the Adviser in the performance of its duties
or from reckless  disregard by the Adviser of the  obligations  and duties under
the Advisory Agreement.

Under the Advisory  Agreement,  the Fund may use the name "John  Hancock" or any
name derived from or similar to it only for so long as the Advisory Agreement or
any extension,  renewal or amendment  thereof remains in effect. If the Advisory
Agreement is no longer in effect,  the Fund (to the extent that it lawfully can)
will cease to use such a name or any other name indicating that it is advised by
or otherwise  connected with the Adviser.  In addition,  the Adviser or the Life
Company may grant the  nonexclusive  right to use the name "John Hancock" or any
similar name to any other  corporation  or entity,  including but not limited to
any investment  company of which the Life Company or any subsidiary or affiliate
thereof or any successor to the business of any subsidiary or affiliate  thereof
shall be the investment adviser.

The continuation of the Advisory Agreement and Distribution Agreement (discussed
below) was  approved by all of the  Trustees.  The Advisory  Agreement,  and the
Distribution Agreement, will continue in effect from year to year, provided that
its  continuance  is approved  annually both (i) by the holders of a majority of
the outstanding voting securities of the Trust or by the Trustees, and (ii) by a
majority of the  Trustees who are not parties to the  Agreement  or  "interested
persons" of any such  parties.  Both  agreements  may be  terminated  on 60 days
written notice by any party or by a vote of a majority of the outstanding voting
securities of the Fund and will terminate automatically if assigned.

For the fiscal  years  ended  October  31, 1995 and 1996 and for the period from
November 1,1996 to May 31, 1997, the Fund paid the Adviser fees in the amount of
$2,514,147, $2,346,755, and $1,218,973, respectively.

Accounting and Legal Services Agreement.  The Trust, on behalf of the Fund, is a
party to an Accounting and Legal Services  Agreement with the Adviser.  Pursuant
to this agreement,  the Adviser  provides the Fund with certain tax,  accounting
and legal  services.  For the fiscal year ended October 31, 1996,  the Fund paid
the Adviser $28,344 under this  agreement.  For the period from November 1, 1996
to May 31, 1997, the Fund paid the Adviser $45,712.

In order to avoid conflicts with portfolio  trades for the Fund, the Adviser and
the Fund have adopted extensive  restrictions on personal  securities trading by
personnel of the Adviser and its  affiliates.  Some of these  restrictions  are:
pre-clearance  for all  personal  trades  and a ban on the  purchase  of initial
public offerings,  as well as contributions to specified charities of profits on
securities held for less than 91 days. These  restrictions are a continuation of
the basic  principle  that the interests of the Fund and its  shareholders  come
first.

DISTRIBUTION CONTRACTS

The Fund has a  Distribution  Agreement  with  John  Hancock  Funds.  Under  the
agreement,  John  Hancock  Funds is  obligated to use their best efforts to sell
shares of each class on behalf of the Fund.  Shares of the Fund are also sold by
selected  broker-dealers (the "Selling Brokers") which have entered into selling
agency agreements with the John Hancock Funds. John Hancock Funds accepts orders
for the purchase of the shares of the Fund that are  continually  offered at net
asset  value next  determined,  plus an  applicable  sales  charge,  if any.  In
connection  with the sale of Class A or Class B shares,  John Hancock  Funds and
Selling Brokers receive compensation from a sales charge imposed, in the case of
Class A shares  at the time of sale.  In the case of Class B shares  the  broker
receives  compensation  immediately  but John Hancock Funds is  compensated on a
deferred  basis.  John  Hancock  Funds may pay extra  compensation  to financial
services firms selling large amounts of fund shares.  This compensation would be
calculated as a percentage of fund shares sold by the firm.

Total  underwriting  commissions  for sales of the Fund's Class A shares for the
fiscal years ended March 31, 1996 was $379,649 and for the period from  November
1, 1996 to May 31, 1997 was $162,187. Of such amounts,  $41,439 and $18,811 were
retained by John Hancock  Funds in 1996 and for the period from November 1, 1996
to May 31, 1997. The remainder of the underwriting commissions were reallowed to
dealers.

The Fund's Trustees adopted Distribution Plans with respect to Class A and Class
B shares (the "Plans"),  pursuant to Rule 12b-1 under the Investment Company Act
of 1940.  Under the Plans the Fund will pay  distribution and service fees at an
aggregate  annual  rate of up to 0.30% and  1.00%,  respectively,  of the Fund's
average  daily net assets  attributable  to shares of that class.  However,  the
service  fee will not  exceed  0.25% of the  Fund's  average  daily  net  assets
attributable  to each class of  shares.  The  distribution  fees will be used to
reimburse the John Hancock Funds for their distribution expenses,  including but
not limited to: (i) initial and ongoing sales  compensation  to Selling  Brokers
and others (including  affiliates of the John Hancock Funds) engaged in the sale
of Fund shares;  (ii) marketing,  promotional and overhead  expenses incurred in
connection with the distribution of Fund shares; and (iii) with respect to Class
B shares only,  interest  expenses on unreimbursed  distribution  expenses.  The
service fees will be used to compensate Selling Brokers and others for providing
personal and account maintenance services to shareholders. In the event the John
Hancock Funds is not fully  reimbursed for payments or expenses they incur under
the Class A Plan,  these  expenses will not be carried beyond twelve months from
the date they were incurred.  Unreimbursed  expenses under the Class B Plan will
be carried forward  together with interest on the balance of these  unreimbursed
expenses.  The Fund does not treat unreimbursed  expenses under the Class B Plan
as a liability of the Fund,  because the Trustees may terminate the Class B Plan
at any time.  For the fiscal year ended May 31, 1997 an aggregate of  $5,738,472
of  distribution  expenses  or 5.53% of the  average  net  assets of the Class B
shares of the Fund,  was not  reimbursed  or recovered by the John Hancock Funds
through the receipt of deferred sales charges or 12b-1 fees in prior periods.

The Plans were approved by a majority of the voting  securities of the Fund. The
Plans and all amendments were approved by the Trustees,  including a majority of
the Trustees who are not  interested  persons of the Fund and who have no direct
or indirect  financial  interest in the operation of the Plans (the "Independent
Trustees"), by votes cast in person at meetings called for the purpose of voting
on these Plans.

                                       27

<PAGE>

Pursuant to the Plans, at least  quarterly,  the John Hancock Funds provides the
Fund  with a  written  report of the  amounts  expended  under the Plans and the
purpose  for which these  expenditures  were made.  The  Trustees  review  these
reports on a quarterly basis to determine their continued appropriateness.

The  Plans  provide  that  they will  continue  in effect  only so long as their
continuance is approved at least annually by a majority of both the Trustees and
the Independent Trustees.  The Plans provide that they may be terminated without
penalty, (a) by a vote of a majority of the Independent Trustees,  (b) by a vote
of a majority of the Fund's  outstanding  shares of the applicable class in each
case  upon  60  days'  written  notice  to  the  John  Hancock  Funds,  and  (c)
automatically  in the event of assignment.  The Plans further  provide that they
may not be amended to increase  the maximum  amount of the fees for the services
described  therein without the approval of a majority of the outstanding  shares
of the class of the Fund which has voting rights with respect to the Plan.  Each
Plan provides that no material  amendment to the Plans will be effective  unless
it is approved by a majority vote of the Trustees and the  Independent  Trustees
of the Fund.  The  holders of Class A and Class B shares have  exclusive  voting
rights with respect to the Plan applicable to their  respective class of shares.
In adopting the Plans, the Trustees concluded that, in their judgment,  there is
a  reasonable  likelihood  that  the  Plans  will  benefit  the  holders  of the
applicable class of shares of the Fund.

Amounts paid to the John  Hancock  Funds by any class of shares of the Fund will
not be used to pay the  expenses  incurred  with  respect to any other  class of
shares of the Fund; provided, however, that expenses attributable to the Fund as
a whole  will be  allocated,  to the extent  permitted  by law,  according  to a
formula based upon gross sales dollars  and/or  average daily net assets of each
such class,  as may be  approved  from time to time by vote of a majority of the
Trustees.  From time to time,  the Fund may  participate  in joint  distribution
activities  with other Funds and the costs of those  activities will be borne by
each Fund in  proportion  to the relative  net asset value of the  participating
Funds.

During the fiscal year ended May 31, 1997,  the Fund paid John Hancock Funds the
following amounts of expenses in connection with their services for the Fund:

NET ASSET VALUE

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

                                       28

<PAGE>

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

Equity  securities  traded on a  principal  exchange or NASDAQ  National  Market
Issues  are  generally  valued  at last  sale  price  on the  day of  valuation.
Securities in the aforementioned  categories for which no sales are reported and
other  securities  traded  over-the-counter  are  generally  valued  at the mean
between the current closing bid and asked prices.

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

Any  assets  or  liabilities  expressed  in  terms  of  foreign  currencies  are
translated  into U.S.  dollars by the  custodian  bank based on London  currency
exchange  quotations as of 5:00 p.m., London time (12:00 noon, New York time) on
the date of any determination of a Fund's NAV.

The NAV for each fund and class is determined  each business day at the close of
regular  trading on the New York Stock  Exchange  (typically  4:00 p.m.  Eastern
Time) by dividing a class's net asset by the number of its shares outstanding.

INITIAL SALES CHARGE ON CLASS A SHARES

Shares of the Fund are  offered at a price equal to their net asset value plus a
sales charge which, at the option of the purchaser, may be imposed either at the
time of purchase (the  "initial  sales charge  alternative")  or on a contingent
deferred basis (the "deferred  sales charge  alternative").  Share  certificates
will not be issued unless requested by the shareholder in writing, and then they
will only be issued for full shares. The Trustees reserve the right to change or
waive a Fund's  minimum  investment  requirements  and to  reject  any  order to
purchase  shares  (including  purchase by exchange)  when in the judgment of the
Adviser such rejection is in the Fund's best interest.

The sales  charges  applicable  to  purchases  of Class A shares of the Fund are
described in the Prospectus. Methods of obtaining reduced sales charges referred
to generally in the Prospectus are described in detail below. In calculating the
sales charge  applicable to current purchases of Class A shares of the Fund, the
investor is entitled to  accumulate  current  purchases  with the greater of the
current  value (at offering  price) of the Class A shares of the Fund,  owned by
the investor, or if John Hancock Signature Services, Inc. ("Signature Services")
is  notified  by the  investor's  dealer  or the  investor  at the  time  of the
purchase, the cost of the Class A shares owned.


Without Sales Charges. Class A shares may be offered without a front-end sales
charge or CDSC to various individuals and institutions as follows:

         oA Trustee/Director or officer of the Fund; a Director or officer
         of the Adviser and its  affiliates  or Selling  Brokers;  employees  or
         sales  representatives  of  any  of the  foregoing;  retired  officers,
         employees  or  Directors  of any  of the  foregoing;  a  member  of the
         immediate  family  (spouse,  children,   grandchildren,   grandparents,
         mother,  father,   sister,   brother,   mother-in-law,   father-in-law,
         daughter-in-law, son-in-law, niece, nephew and domestic partner) of any
         
                                       29
<PAGE>

         of the foregoing; or any fund, pension, profit sharing or other benefit
         plan for the individuals described above.

         oA broker,  dealer,  financial planner,  consultant or registered
         investment  advisor that has entered into a signed  agreement with John
         Hancock  Funds  providing  specifically  for the use of Fund  shares in
         fee-based  investment  products or  services  made  available  to their
         clients.

         oA former  participant  in an  employee  benefit  plan  with John
         Hancock  funds,  when he or she  withdraws  from  his or her  plan  and
         transfers any or all of his or her plan  distributions  directly to the
         Fund.

         oA member of a class action lawsuit against  insurance  companies
         who is investing settlement proceeds.

         oRetirement plans participating in Merrill Lynch servicing programs, if
         the Plan has more than $3 million in assets or 500 eligible employees
         at the date the Plan Sponsor signs the Merrill Lynch Recordkeeping
         Service Agreement. See your Merrill Lynch financial consultant for
         further information.

         oRetirement plans investing through the PruArray Program sponsored by
         Prudential Securities.

         oExisting full service clients of the Life Company who were group
         annuity  contract  holders as of  September  1, 1994,  and  participant
         directed  retirement plans with at least 100 eligible  employees at the
         inception of the Fund  account.  Each of these  investors  may purchase
         Class A shares with no initial sales charge. However, if the shares are
         redeemed  within 12 months after the end of the calendar  year in which
         the purchase was made, a CDSC will be imposed at the following rate:


Amount Invested                           CDSC Rate
- ---------------                           ---------
$1 to $4,999,999                            1.00%
Next $5 million to $9,999,999               0.50%
Amounts of $10 million and over             0.25%

Class A shares  may  also be  purchased  without  an  initial  sales  charge  in
connection  with  certain  liquidation,   merger  or  acquisition   transactions
involving other investment companies or personal holding companies.

Combination  Privilege.  In calculating the sales charge applicable to purchases
of Class A shares  made at one time,  the  purchases  will be combined to reduce
sales charges if made by (a) an individual, his or her spouse and their children
under the age of 21, purchasing  securities for his or their own account,  (b) a
trustee or other  fiduciary  purchasing for a single trust,  estate or fiduciary
account and (c) groups  which  qualify  for the Group  Investment  Program  (see
below).   Further  information  about  combined  purchases,   including  certain
restrictions on combined group purchases,  is available from Signature  Services
or a Selling Broker's representative.


Accumulation Privilege.  Investors (including investors combining purchases) who
are  already  Class A  shareholders  may also  obtain the benefit of the reduced

                                       30
<PAGE>

sales charge by taking into account not only the amount being  invested but also
the investor's purchase price or current value of the Class A shares of all John
Hancock  funds which carry a sales charge  already held by such person.  Class A
shares  of John  Hancock  money  market  funds  will  only be  eligible  for the
accumulation privilege if the investor has previously paid a sales charge on the
amount of those shares. Retirement plan investors may include the value of Class
b shares if class B shares held are greater  than $1 million.  Retirement  plans
must notify Signature Services to utilize.


Group Investment Program. Under the Combination and Accumulation Privileges, all
members of a group may combine their  individual  purchases of Class A shares to
potentially  qualify for breakpoints in the sales charge schedule.  This feature
is  provided  to any  group  which (1) has been in  existence  for more than six
months,  (2) has a  legitimate  purpose  other than the  purchase of mutual fund
shares at a discount for its members,  (3) utilizes salary  deduction or similar
group methods of payment, and (4) agrees to allow sales materials of the fund in
its mailings to members at a reduced or no cost to John Hancock Funds.


Letter of Intention.  Reduced sales charges are also  applicable to  investments
pursuant to a Letter of Intention  (the "LOI"),  which should be read  carefully
prior to its execution by an investor. The Fund offers two options regarding the
specified  period for making  investments  under the LOI. All investors have the
option of making  their  investments  over a specified  period of thirteen  (13)
months.  Investors  who are using the Fund as a funding  medium for a retirement
plan, however,  may opt to make the necessary  investments called for by the LOI
over  a  forty-eight   (48)  month  period.   These   retirement  plans  include
Traditional,  Roth and Education IRAs, SEP, SARSEP,  401(k),  403(b)  (including
TSAs),  SIMPLE IRA, SIMPLE 401(k),  Money Purchase  Pension,  Profit Sharing and
Section 457 plans. Such an investment (including  accumulations and combinations
but not including reinvested  dividends) must aggregate $50,000 or more invested
during  the  specified  period  from the  date of the LOI or from a date  within
ninety (90) days prior thereto, upon written request to Signature Services.  The
sales charge  applicable to all amounts invested under the LOI is computed as if
the aggregate amount intended to be invested had been invested  immediately.  If
such  aggregate  amount is not actually  invested,  the  difference in the sales
charge actually paid and the sales charge payable had the LOI not been in effect
is due from the investor.  However,  for the purchases  actually made within the
specified  period (either 13 or 48 months) the sales charge  applicable will not
be higher than that which would have been applied  (including  accumulations and
combinations) had the LOI been for the amount actually invested.


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

DEFERRED SALES CHARGE ON CLASS B SHARES

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

                                       31

<PAGE>

Contingent  Deferred Sales Charge.  Class B shares which are redeemed within six
years of purchase will be subject to a contingent deferred sales charge ("CDSC")
at the rates set forth in the  Prospectus  as a percentage  of the dollar amount
subject  to the CDSC.  The charge  will be  assessed  on an amount  equal to the
lesser of the current market value or the original  purchase cost of the Class B
shares being  redeemed.  No CDSC will be imposed on  increases in account  value
above  the  initial   purchase   prices,   including  all  shares  derived  from
reinvestment of dividends or capital gains distributions.


Class B shares are not available to full-service  retirement plans  administered
by  Signature  Services  or the Life  Company  that had more  than 100  eligible
employees at the inception of the Fund account.


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

In determining  whether a CDSC applies to a redemption,  the calculation will be
determined in a manner that results in the lowest  possible rate being  charged.
It will be assumed  that your  redemption  comes first from shares you have held
beyond  the six year  CDSC  redemption  period  or those  you  acquired  through
dividend and capital gain  reinvestment,  and next from the shares you have held
the longest  during the six year  period.  For this  purpose,  the amount of any
increase in a share's value above its initial  purchase price is not regarded as
a share exempt from CDSC.  Thus,  when a share that has  appreciated in value is
redeemed during the CDSC period, a CDSC is assessed only on its initial purchase
price.

When requesting a redemption for a specific dollar amount please indicate if you
require the proceeds to equal the dollar  amount  requested.  If not  indicated,
only the  specified  dollar  amount will be redeemed  from your  account and the
proceeds will be less any applicable CDSC.

Example:

You have  purchased  100  shares at $10 per share.  The  second  year after your
purchase,  your  investment's  net asset value per share has  increased by $2 to
$12, and you have gained 10 additional shares through dividend reinvestment.  If
you redeem 50 shares at this time your CDSC will be calculated as follows:


         oProceeds of 50 shares redeemed at $12 per shares (50 x 12)    $600.00
         o*Minus Appreciation ($12 - $10) x 100 shares                  (200.00)
         oMinus proceeds of 10 shares not subject to CDSC 
          (dividend reinvestment)                                       (120.00)
                                                                         ------
         oAmount subject to CDSC                                        $280.00

         *The appreciation is based on all 100 shares in the lot not just the 
          shares being redeemed.

Proceeds from the CDSC are paid to the  Distributors and are used in whole or in
part  by  the  Distributors  to  defray  their  expenses  related  to  providing
distribution-related  services  to the Fund in  connection  with the sale of the
Class B shares,  such as the payment of  compensation  to select Selling Brokers
for selling Class B shares. The combination of the CDSC and the distribution and

                                       32

service  fees  facilitates  the  ability  of the Fund to sell the Class B shares
without a sales charge being deducted at the time of the purchase.

redemptions  of Class B shares and of Class A shares  that are  subject to CDSC,
unless indicated otherwise, in the circumstance defined below:

         account  value,  including  reinvested  dividends,   at  the  time  you
         established  your  periodic  withdrawal  plan  and 12% of the  value of
         subsequent  investments (less  redemptions) in that account at the time
         you notify Signature Services. (Please note, this waiver does not apply
         to  periodic  withdrawal  plan  redemptions  of Class A shares that are
         subject to a CDSC.)

*        Redemptions by Retirement plans participating in Merrill Lynch

         Profit-Sharing Plan).

*        Redemptions from certain IRA and retirement plans that purchased shares

If you qualify for a CDSC waiver under one of these situations, you must notify
Signature Services at the time you make your redemption. The waiver will be
granted once Signature Services has confirmed that you are entitled to the
waiver.




SPECIAL REDEMPTIONS

Although  it  would  not  normally  do so,  the  Fund  has the  right to pay the
redemption  price  of  shares  of the  Fund in  whole  or in  part in  portfolio
securities as prescribed by the Trustees.  When the shareholder  sells portfolio
securities  received in this  fashion,  the  shareholder  will incur a brokerage
charge.  Any such  securities  would be valued for the  purposes  of making such
payment at the same value as used in determining net asset value.  The Fund has,
however,  elected to be governed by Rule 18f-1 under the Investment Company Act.
Under that rule,  the Fund must  redeem its shares for cash except to the extent
that the redemption  payments to any shareholder during any 90- day period would
exceed  the  lesser of  $250,000  or 1% of the  Fund's  net  asset  value at the
beginning of such period.

ADDITIONAL SERVICES AND PROGRAMS

Exchange  Privilege.  The Fund  permits  exchanges of shares of any class of the
Fund for shares of the same class in any other John Hancock fund  offering  that
class.

Exchanges  between funds with shares that are not subject to a CDSC are based on
their  respective net asset values.  No sales charge or  transactions  charge is
imposed.  Shares of the Fund which are subject to a CDSC may be  exchanged  into
shares of any of the other John Hancock funds that are subject to a CDSC without
incurring the CDSC; however,  the shares acquired in an exchange will be subject
to the CDSC schedule of the shares acquired if and when such shares are redeemed
(except that shares exchanged into John Hancock Short-Term Strategic Income Fund
and John Hancock Intermediate Maturity Government Fund will retain the exchanged
fund's  CDSC  schedule).  For  purposes  of  computing  the  CDSC  payable  upon
redemption of shares acquired in an exchange, the holding period of the original
shares is added to the holding period of the shares acquired in an exchange.

If a shareholder  exchanges  Class B shares  purchased  prior to January 1, 1994
(except John Hancock Short-Term Strategic Income Fund) for Class B shares of any
other John Hancock fund, the acquired  shares will continue to be subject to the
CDSC schedule that was in effect when the exchanged shares were purchased.

The Fund  reserves the right to require that  previously  exchanged  shares (and
reinvested  dividends)  be in the  Fund  for 90 days  before  a  shareholder  is
permitted a new exchange.

The Fund may  refuse  any  exchange  order.  The Fund may  changed or cancel its
exchange policies at any time, upon 60 days' notice to its shareholders.

An exchange of shares is treated as a  redemption  of shares of one fund and the
purchase of shares of another for Federal  Income Tax purposes.  An exchange may
result in a taxable gain or loss. See "TAX STATUS".

Systematic  Withdrawal Plan. The Fund permits the  establishment of a Systematic
Withdrawal  Plan.  Payments under this plan represent  proceeds arising from the
redemption  of Fund shares which may result in  realization  of gain or loss for
purposes  of  Federal,  state and  local  income  taxes.  The  maintenance  of a
Systematic  Withdrawal Plan concurrently with purchases of additional Class A or

                                       35
<PAGE>

Class B shares of the Fund could be disadvantageous to a shareholder  because of
the initial  sales  charge  payable on such  purchases of Class A shares and the
CDSC  imposed on  redemptions  of Class B shares  and  because  redemptions  are
taxable events. Therefore, a shareholder should not purchase Class A and Class B
shares at the same time a  Systematic  Withdrawal  Plan is in  effect.  The Fund
reserves the right to modify or discontinue  the Systematic  Withdrawal  Plan of
any  shareholder  on 30 days' prior written  notice to such  shareholder,  or to
discontinue  the  availability  of such plan in the future.  The shareholder may
terminate the plan at any time by giving proper notice to Signature Services.

Monthly Automatic Accumulation Program ("MAAP"). This program is explained in
the Prospectus. The program, as it relates to automatic investment checks, is
subject to the following conditions:

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

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

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

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

To protect the interests of other investors in the Fund, the Fund may cancel the
reinvestment  privilege  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. Also, the Fund may refuse any reinvestment
request.

The Fund may change or cancel its reinvestment policies at any time.

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

Retirement plans participating in Merrill Lynch's servicing programs:

Class A shares  are  available  at net asset  value for plans with $3 million in
plan assets or 500 eligible  employees  at the date the Plan  Sponsor  signs the
Merrill Lynch Recordkeeping Service Agreement.  If the plan does not meet either
of these limits, Class A shares are not available.

For  participating  retirement  plans  investing in Class B shares,  shares will
convert  to Class A shares  after  eight  years.  or sooner if the plan  attains
assets of $5 million (by means of a CDSC-free  redemption/purchase  at net asset
value).

DESCRIPTION OF THE FUND'S SHARES

The Trustees of the Trust are  responsible for the management and supervision of
the Fund.  The  Declaration  of Trust permits the Trustees to issue an unlimited
number of full and fractional shares of beneficial interest of the Fund, without
par value.  Under the  Declaration of Trust,  the Trustees have the authority to
create and classify shares of beneficial  interest in separate  series,  without
further action by  shareholders.  As of the date of this Statement of Additional
Information,  the  Trustees  have  authorized  the  creation of two series.  The
Trustees have also authorized the issuance of two classes of shares of the Fund,
designated as Class A and Class B.

The shares of each class of the Fund represent an equal  proportionate  interest
in the aggregate net assets attributable to that classes of the Fund. Holders of
Class A and Class B shares  have  certain  exclusive  voting  rights on  matters
relating to their respective  distribution  plans. The different  classes of the
Fund may bear  different  expenses  relating to the cost of holding  shareholder
meetings necessitated by the exclusive voting rights of any class of shares.

Dividends paid by the Fund, if any, with respect to each class of shares will be
calculated in the same manner,  at the same time and on the same day and will be
in the same amount, except for differences resulting from the facts that (i) the
distribution and service fees relating to the Class A and Class B shares will be
borne exclusively by that class (ii) Class B shares will pay higher distribution
and  service  fees than  Class A shares  and  (iii)  each of Class A and Class B
shares will bear any other class  expenses  properly  allocable to that class of
shares,  subject to the conditions  the Internal  Revenue  Service  imposes with
respect to the  multiple-class  structures.  Similarly,  the net asset value per
share may vary depending on whether Class A or Class B shares are purchased.  No
interest will be paid on uncashed dividend or redemption checks.

In the event of  liquidation,  shareholders  of each class are entitled to share
pro rata in the net  assets  of the Fund  available  for  distribution  to these
shareholders.  Shares  entitle their  holders to one vote per share,  are freely
transferable  and have no preemptive,  subscription or conversion  rights.  When
issued, shares are fully paid and non-assessable, except as set forth below.

Unless  otherwise  required  by  the  Investment  Company  Act  of  1940  or the
Declaration of Trust,  the Fund has no intention of holding  annual  meetings of
shareholders.  Fund shareholders may remove a Trustee by the affirmative vote of
at least two-thirds of the Trust's  outstanding  shares,  and the Trustees shall
promptly  call a meeting for such purpose when  requested to do so in writing by
the record holders of not less than 10% of the outstanding  shares of the Trust.
Shareholders   may,  under  certain   circumstances,   communicate   with  other
shareholders in connection with a requesting a special meeting of  shareholders.
However,  at any time that less than a majority of the Trustees  holding  office
were elected by the  shareholders,  the Trustees will call a special  meeting of
shareholders for the purpose of electing Trustees.

                                       37

Under Massachusetts law,  shareholders of a Massachusetts  business trust could,
under certain  circumstances,  be held personally liable for acts or obligations
of the Trust.  However,  the Fund's  Declaration  of Trust  contains  an express
disclaimer  of  shareholder  liability for acts,  obligations  or affairs of the
Fund.  The  Declaration  of Trust also provides for  indemnification  out of the
Fund's  assets for all losses and expenses of any  shareholder  held  personally
liable by reason of being or having been a shareholder. The Declaration of Trust
also provides that no series of the Trust shall be liable for the liabilities of
any other series.  Furthermore, no fund included in this Fund's prospectus shall
be liable for the  liabilities  of any other John  Hancock  Fund.  Liability  is
therefore  limited to  circumstances in which the Fund itself would be unable to
meet its obligations, and the possibility of this occurrence is remote.


The Fund reserves the right to reject any  application  which conflicts with the
Fund's  internal  policies or the  policies of any  regulatory  authority.  John
Hancock Funds does not accept starter or credit card checks. All checks returned
by the post office as undeliverable will be reinvested at net asset value in the
fund or  funds  from  which a  redemption  was  made or  dividend  paid.  Use of
information  provided  on the  account  application  may be used by the  Fund to
verify the accuracy of the  information or for  background or financial  history
purposes.  A joint account will be administered as a joint tenancy with right of
survivorship,  unless the joint owners notify Signature  Services of a different
intent.  A shareholder's  account is governed by the laws of The Commonwealth of
Massachusetts.


TAX STATUS

Each series of the Trust including the Fund, is treated as a separate entity for
tax purposes.  The Fund has qualified as a "regulated  investment company" under
Subchapter M of the Internal Revenue Code of 1986, as amended (the "Code"),  and
intends  to  continue  to so  qualify  for  each  taxable  year.  As such and by
complying  with the  applicable  provisions of the Code regarding the sources of
its income,  the timing of its  distributions,  and the  diversification  of its
assets, the Fund will not be subject to Federal income tax on its taxable income
(including net realized  capital gains) which is distributed to  shareholders in
accordance with the timing requirements of the Code.

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

Distributions  from the  Fund's  current or  accumulated  earnings  and  profits
("E&P") will be taxable  under the Code for investors who are subject to tax. If
these  distributions  are  paid  from the  Fund's  "investment  company  taxable
income," they will be taxable as ordinary income;  and if they are paid from the
Fund's "net capital  gain," they will be taxable as capital  gain.  (Net capital
gain is the excess (if any) of net  long-term  capital gain over net  short-term
capital loss,  and investment  company  taxable income is all taxable income and
capital  gains,  other than those  gains and losses  included in  computing  net
capital gain,  after  reduction by deductible  expenses.) As a result of federal
tax legislation  enacted on August 5, 1997,  gain  recognized  after May 6, 1997
from the  sale of a  capital  asset  is  taxable  to  individual  (noncorporate)
investors at different  maximum  federal income tax rates,  depending  generally
upon the tax holding period for the asset, the federal income tax bracket of the
taxpayer,  and the dates  the  asset was  acquired  and/or  sold.  The  Treasury
Department  has  issued  guidance  under the Act that  enables  the Fund to pass
through to its  shareholders  the benefits of the capital gains rates enacted in
the Act.  Shareholders  should  consult  their own tax  advisers  on the correct

                                       38
<PAGE>

application of these new rules.  Some  distributions  may be paid in January but
may be taxable to  shareholders  as if they had been  received on December 31 of
the previous year. The tax treatment  described  above will apply without regard
to whether distributions are received in cash or reinvested in additional shares
of the Fund.

Distributions,  if any,  in excess of E&P will  constitute  a return of  capital
under the Code, which will first reduce an investor's  federal tax basis in Fund
shares and then, to the extent such basis is exceeded,  will generally give rise
to capital gains.  Shareholders who have chosen automatic  reinvestment of their
distributions  will have a federal tax basis in each share received  pursuant to
such a  reinvestment  equal to the amount of cash they would have  received  had
they  elected  to receive  the  distribution  in cash,  divided by the number of
shares received in the reinvestment.

Foreign  exchange  gains and  losses  realized  by the Fund in  connection  with
certain transactions involving foreign  currency-denominated debt securities are
subject to Section 988 of the Code, which generally causes such gains and losses
to be treated as ordinary  income and losses and may affect the  amount,  timing
and character of distributions to shareholders.

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

Upon a  redemption  or other  disposition  of shares of the Fund  (including  by
exercise of the exchange  privilege) in a transaction  that is treated as a sale
for tax  purposes,  a shareholder  may realize a taxable gain or loss  depending
upon the amount of the proceeds  and the  investor's  basis in his shares.  Such
gain or loss will be treated as capital  gain or loss if the shares are  capital
assets in the  shareholder's  hands.  A sales charge paid in purchasing  Class A
shares of the Fund cannot be taken into account for purposes of determining gain
or loss on the  redemption or exchange of such shares within 90 days after their
purchase to the extent  Class A shares of the Fund or another  John Hancock Fund
are  subsequently  acquired  without  payment of a sales charge  pursuant to the
reinvestment or exchange  privilege.  This disregarded  charge will result in an
increase in the  shareholder's  tax basis in the shares  subsequently  acquired.
Also,  any loss  realized on a redemption  or exchange may be  disallowed to the
extent the shares  disposed of are replaced with other shares of the Fund within
a period of 61 days beginning 30 days before and ending 30 days after the shares
are disposed of, such as pursuant to automatic dividend reinvestments. In such a
case,  the  basis  of the  shares  acquired  will be  adjusted  to  reflect  the
disallowed  loss.  Any loss  realized  upon the  redemption of shares with a tax
holding period of six months or less will be treated as a long-term capital loss
to the extent of any amounts treated as distributions of long-term  capital gain
with respect to such shares.  Shareholders should consult their own tax advisers
regarding their particular  circumstances to determine  whether a disposition of
Fund shares is properly treated as a sale for tax purposes, as is assumed in the
foregoing  discussion.  Also,  future  Treasury  Department  guidance  issued to
implement the Act may contain additional rules for determining the tax treatment
of sales of Fund shares held for various  periods,  including  the  treatment of
losses on sales of shares  held for six months or less that are  recharacterized
as long-term capital losses, as described above.

                                       39

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

For Federal  income tax  purposes,  the Fund is permitted to carry forward a net
capital loss in any year to offset its own net capital gains, if any, during the
eight years following the year of the loss. To the extent subsequent net capital
gains are offset by such  losses,  they  would not result in Federal  income tax
liability to the Fund, as noted above,  and would not be  distributed as such to
shareholders.  The  capital  loss  carryforwards  for the Fund  are as  follows:
$48,876,888  of capital  loss  carryforwards  which will  expire May 31, 1998 --
$282,637, May 31, 2002-- $16,549,431,  May 31, 2003 -- $26,193,155, May 31, 2004
- --$3,597,046 and May 31, 2005 --$2,254,619.

The Fund's  dividends  and  distributions  will not  qualify  for the  corporate
dividends-received deduction.

A Fund is required to accrue income on any debt securities that have more than a
de minims amount of original  issue discount (or debt  securities  acquired at a
market  discount,  if the Fund  elects  to  include  market  discount  in income
currently) prior to the receipt of the corresponding cash payments.  The mark to
market  rules  applicable  to certain  options  and futures  contracts  may also
require  the Fund to  recognize  gain  without  a  concurrent  receipt  of cash.
However,  the  Fund  must  distribute  to  shareholders  for each  taxable  year
substantially all of its net income and net capital gains, including such income
or gain, to qualify as a regulated  investment  company and avoid  liability for
any federal income or excise tax. Therefore, the Fund may have to dispose of its
portfolio  securities under  disadvantageous  circumstances to generate cash, or
borrow cash, to satisfy these distribution requirements.

A state  income (and  possibly  local income  and/or  intangible  property)  tax
exemption is generally available to the extent (if any) the Fund's distributions
are derived from interest on (or, in the case of intangible  property taxes, the
value of its assets is  attributable  to) certain U.S.  Government  obligations,
provided in some states that certain thresholds for holdings of such obligations
and/or reporting  requirements are satisfied.  The Fund will not seek to satisfy
any  threshold or reporting  requirements  that may apply in  particular  taxing
jurisdictions,  although the Fund may in its sole  discretion  provide  relevant
information to shareholders.

The Fund will be required to report to the Internal  Revenue Service (the "IRS")
all taxable  distributions to  shareholders,  as well as gross proceeds from the
redemption  or exchange  of Fund  shares,  except in the case of certain  exempt
recipients,  i.e.,  corporations  and certain other investors  distributions  to

                                       40
<PAGE>

which are exempt from the information  reporting  provisions of the Code.  Under
the backup withholding  provisions of Code Section 3406 and applicable  Treasury
regulations,  all such reportable  distributions  and proceeds may be subject to
backup  withholding  of  federal  income  tax at the  rate of 31% in the case of
non-exempt shareholders who fail to furnish the Fund with their correct taxpayer
identification number and certain  certifications  required by the IRS or if the
IRS or a broker  notifies the Fund that the number  furnished by the shareholder
is  incorrect  or that the  shareholder  is subject to backup  withholding  as a
result of failure to report interest or dividend income.  The Fund may refuse to
accept an application that does not contain any required taxpayer identification
number or  certification  that the number  provided  is  correct.  If the backup
withholding  provisions are  applicable,  any such  distributions  and proceeds,
whether taken in cash or  reinvested  in shares,  will be reduced by the amounts
required  to be  withheld.  Any  amounts  withheld  may be  credited  against  a
shareholder's U.S. federal income tax liability.  Investors should consult their
tax advisers about the applicability of the backup withholding provisions.

The Fund may be  required to account for its  transactions  in forward  rolls or
swaps,  caps, floors and collars in a manner that, under certain  circumstances,
may limit the extent of its  participation in such  transactions.  Additionally,
the Fund may be required to  recognize  gain,  but not loss,  if a swap or other
transaction  is  treated  as a  constructive  sale of an  appreciated  financial
position in the Fund's portfolio. The Fund may have to sell portfolio securities
under disadvantageous circumstances to generate cash, or borrow cash, to satisfy
these distribution requirements.

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

Limitations imposed by the Code on regulated  investment companies like the Fund
may restrict the Fund's ability to enter into futures and options transactions.

Certain  options and futures  transactions  undertaken by the Fund may cause the
Fund to  recognize  gains or losses  from  marking  to market  even  though  its
positions have not been sold or terminated and affect the character as long-term
or short-term and timing of some capital gains and losses  realized by the Fund.
Additionally,  the Fund may be required to recognize  gain,  but not loss, if an
option or other  transaction is treated as a constructive sale of an appreciated
financial  position in the Fund's portfolio.  Also, certain of the Fund's losses
on its  transactions  involving  options,  futures or forward  contracts  and/or
offsetting or successor  portfolio  positions may be deferred  rather than being
taken into account  currently in calculating the Fund's taxable income or gains.
Certain of these  transactions may also cause the Fund to dispose of investments
sooner than would  otherwise have  occurred.  These  transactions  may therefore
affect  the  amount,  timing  and  character  of  the  Fund's  distributions  to
shareholders.  The Fund will take into account the special tax rules  (including
consideration of available elections) applicable to options, futures and forward
contracts in order to minimize any potential adverse tax consequences.

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

                                       41
<PAGE>

advisers as to the  Federal,  state or local tax  consequences  of  ownership of
shares  of, and  receipt of  distributions  from,  the Fund in their  particular
circumstances.

Non-U.S.  investors  not engaged in a U.S.  trade or  business  with which their
investment in the Fund is effectively  connected will be subject to U.S. Federal
income  tax  treatment  that is  different  from  that  described  above.  These
investors may be subject to nonresident alien withholding tax at the rate of 30%
(or a lower rate under an applicable tax treaty) on amounts  treated as ordinary
dividends  from the Fund and,  unless an  effective  IRS Form W-8 or  authorized
substitute  for Form W-8 is on file, to 31% backup  withholding on certain other
payments from the Fund.  Non-U.S.  investors  should  consult their tax advisers
regarding such  treatment and the  application of foreign taxes to an investment
in the Fund.

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

CALCULATION OF PERFORMANCE

For the 30 day period ending November 30, 1997, the yield on Class A and Class B
shares of the Fund was 5.10% and 4.63%,  respectively.  The average total return
of Class A shares of the Fund for the 1 year, 5 years and period from January 3,
1992  (inception of the Fund) to November 30, 1997 were 1.88%,  5.73% and 5.57%,
respectively.

The  average  total  return of Class B shares of the 1 year,  5 year and 10 year
periods ended November 30, 1997 were 1.06%,  5.88% and 8.07%,  respectively  and
reflects the applicable CDSC.

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

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

Where:

         a =      dividends and interest earned during the period.
         b =      net expenses accrued during the period.
         c =      the average daily number of shares of the Fund  outstanding
                  during the period that would be entitled to receive dividends.
         d =      the maximum  offering price per share on the last day of the 
                  period (NAVE where applicable).

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

                                       42
<PAGE>
               n ________
          T = \ / ERV / P - 1 

Where:

         P =      a hypothetical initial investment of $1,000.
         T =      average annual total return
         n =      number of years
         ERV=     ending  redeemable value of a hypothetical  $1,000  investment
                  made at designated periods or fraction thereof.

Because each class has its own sales charge and fee structure,  the classes have
different  performance  results.  In the case of Class A or Class B shares, this
calculation  assumes  the  maximum  sales  charge  is  included  in the  initial
investment  or the CDSC  applied at the end of the  period,  respectively.  This
calculation  assumes that all dividends and  distributions are reinvested at net
asset value on the reinvestment dates during the period. The "distribution rate"
is determined by  annualizing  the result of dividing the declared  dividends of
the Fund  during the period  stated by the maximum  offering  price or net asset
value at the end of the  period.  Excluding  the Fund's  sales  charge  from the
distribution rate produces a higher rate.

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

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

Performance  rankings and ratings  reported  periodically in national  financial
publications  such as MONEY  Magazine,  FORBES,  BUSINESS  WEEK, THE WALL STREET
JOURNAL,  MICROPAL,  INC.,  MORNINGSTAR,  STANGER'S  and  BARRON'S,  may also be
utilized.  The Fund's promotional and sales literature may make reference to the
Fund's  "beta." Beta is a reflection of the  market-related  risk of the Fund by
showing how responsive the Fund is to the market.

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

BROKERAGE ALLOCATION

Decisions  concerning  the  purchase and sale of  portfolio  securities  and the
allocation  of  brokerage  commissions  are  made  by the  Adviser  pursuant  to
recommendations made by an investment  committee of the Adviser,  which consists
of officers  and  directors of the Adviser and  affiliates  and Trustees who are
interested persons of the Fund. Orders for purchases and sales of securities are
placed in a manner  which,  in the opinion of the  Adviser,  will offer the best
price and market for the  execution  of each such  transaction.  Purchases  from
underwriters  of portfolio  securities  may include a commission or  commissions
paid by the issuer  and  transactions  with  dealers  serving  as market  makers
reflect a "spread." Debt securities are generally  traded on a net basis through
dealers  acting  for their own  account as  principals  and not as  brokers;  no
brokerage commissions are payable on these transactions.

In the U.S. and in some other countries,  debt securities are traded principally
in the  over-the-counter  market on a net basis through dealers acting for their
own  account  and not as  brokers.  Ion other  countries,  both debt and  equity
securities  are traded on exchanges at fixed  commission  rates.  Commissions on
foreign  transactions are generally higher than the negotiated  commission rates
available  in the U.S.  There  is  generally  less  government  supervision  and
regulation of foreign stock exchanges and broker-dealers than in the U.S.

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

To the extent  consistent  with the foregoing,  the Fund will be governed in the
selection of brokers and dealers,  and the  negotiation of brokerage  commission
rates and dealer  spreads,  by the  reliability  and  quality  of the  services,
including primarily the availability and value of research  information and to a
lesser extent statistical  assistance  furnished to the Adviser of the Fund, and
their value and expected  contribution to the performance of the Fund. It is not
possible to place a dollar value on information and services to be received from
brokers and dealers,  since it is only  supplementary to the research efforts of
the  Adviser.  The receipt of  research  information  is not  expected to reduce
significantly  the  expenses  of  the  Adviser.  The  research  information  and
statistical  assistance  furnished  by brokers  and dealers may benefit the Life
Company or other  advisory  clients of the Adviser,  and  conversely,  brokerage
commissions and spreads paid by other advisory clients of the Adviser may result
in research information and statistical  assistance  beneficial to the Fund. The
Fund  will make no  commitments  to  allocate  portfolio  transactions  upon any
prescribed  basis.  While the Fund's officers will be primarily  responsible for
the allocation of the Fund's brokerage business, their policies and practices in
this  regard  must be  consistent  with the  foregoing  and will at all times be
subject to review by the  Trustees.  For the period  ended  October 31, 1996 and
1995 and for the period  from  November 1, 1996 to May 31,  1997,  the Fund paid
negotiated  brokerage   commissions  of  $169,518,   $107,825,   and  $  97,937,
respectively.

As permitted by Section 28(e) of the  Securities  Exchange Act of 1934, the Fund
may pay to a broker which provides  brokerage and research  services to the Fund
an amount of disclosed  commission  in excess of the  commission  which  another
broker would have  charged for  effecting  that  transaction.  This  practice is

                                       44
<PAGE>

subject  to a good  faith  determination  by the  Trustees  that  the  price  is
reasonable  in light of the services  provided and to policies that the Trustees
may adopt from time to time.  For the period  ended  November 1, 1996 to May 31,
1997,  the Fund did not pay  commissions  as  compensation  to any  brokers  for
research services such as industry, economic and company reviews and evaluations
of securities.

The  Adviser's  indirect  parent,  the  Life  Company,   is  the  indirect  sole
shareholder of John Hancock Distributors,  Inc. a broker-dealer  ("Distributors"
or Affiliated  Broker").  Pursuant to procedures  determined by the Trustees and
consistent  with the above  policy of obtaining  best net results,  the Fund may
execute  portfolio  transactions  with or through  Affiliated  Brokers.  For the
period ended  October 31, 1995 and 1996 and for the period from November 1, 1996
to May 1, 1997,  the Fund did not execute any  portfolio  transactions  with the
Affiliated Broker.

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

Other investment  advisory clients advised by the Adviser may also invest in the
same  securities as the Fund. When these clients buy or sell the same securities
at  substantially  the same time, the Adviser may average the transactions as to
price and  allocate the amount of  available  investments  in a manner which the
Adviser  believes to be equitable to each client,  including  the Fund.  In some
instances,  this  investment  procedure may  adversely  affect the price paid or
received by the Fund or the size of the position obtainable for it. On the other
hand, to the extent permitted by law, the Adviser may aggregate securities to be
sold or  purchased  for the Fund with  those to be sold or  purchased  for other
clients managed by it in order to obtain best execution.

TRANSFER AGENT SERVICES

John Hancock Signature Services,  Inc., 1 John Hancock Way , Suite 1000, Boston,
MA  02217-1000 a wholly-  owned  indirect  subsidiary of the Life Company is the
transfer and dividend  paying agent for the Fund. The Fund pays an annual fee of
$20.00  for each  Class A  shareholder  account  and  $22.50  for  each  Class B
shareholder account,  plus certain  out-of-pocket  expenses.  These expenses are
aggregated  and charged to the Fund and  allocated to each class on the basis of
their relative net asset value.

APPENDIX A

DESCRIPTION OF BOND RATINGS*

Moody's Bond Ratings

Bonds.  "Bonds which are rated 'Aaa' are judged to be of the best quality.  They
carry the smallest  degree of investment  risk and are generally  referred to as
'gilt edge.' Interest  payments are protected by a large or by an  exceptionally
stable margin and principal is secure. While the various protective elements are
likely to change,  such changes as can be visualized are most unlikely to impair
the fundamentally strong position of such issues.

"Bonds which are rated 'Aa' are judged to be of high  quality by all  standards.
Together with the 'Aaa' group they  comprise  what are  generally  known as high
grade  bonds.  They are rated  lower  than the best  bonds  because  margins  of
protection  may  not be as  large  as in  'Aaa'  securities  or  fluctuation  of
protective  elements may be of grater  amplitude or there may be other  elements
present  which make the long term risks  appear  somewhat  larger  than in 'Aaa'
securities  .  "Bonds  which are rated 'A'  possess  many  favorable  investment
attributes and are to be considered as upper medium grade  obligations.  Factors
giving  security to principal and interest are considered  adequate but elements
may be present which  suggest a  susceptibility  to  impairment  sometime in the
future.

"Bonds which are rated 'Baa' are considered as medium grade  obligations,  i.e.,
they are neither  highly  protected nor poorly  secured.  Interest  payments and
principal  security  appear  adequate  for the present  but  certain  protective
elements may be lacking or may be  characteristically  unreliable over any great
length of time. Such bonds lack outstanding  investment  characteristics  and in
fact have speculative characteristics as well.

"Bonds  which are rated  'Ba' are  judged to have  speculative  elements;  their
future cannot be considered  as well assured.  Often the  protection of interest
and  principal  payments may be very  moderate and thereby not well  safeguarded
during  both  good and bad  times  over the  future.  Uncertainty  of  position,
characterizes bonds in this class.

"Bonds  which are rated 'B'  generally  lack  characteristics  of the  desirable
investment.  Assurance of interest and principal  payments or of  maintenance of
other terms of the contract over any long period of time may be small.

Where no rating has been assigned or where a rating has been suspended or
withdrawn, it may be for reasons unrelated to the quality of the issue. Should
no rating be assigned, the reason may be one of the following: (i) an
application for rating was not received or accepted; (ii) the issue or issuer
belongs to a group of securities that are not rated as a matter of policy; (iii)
there is a lack of essential data pertaining to the issue or issuer; or (iv) the
issue was privately placed, in which case the rating is not published in Moody's
publications.

Suspension or withdrawal may occur if new and material  circumstances arise, the
effects of which preclude satisfactory analysis; if there is no longer available
reasonable  up-to-date  data to permit a  judgment  to be  formed;  if a bond is
called for redemption; or for other reasons.

Standard & Poor's Bond Ratings

"AAA. Debt rated 'AAA' has the highest rating by Standard & Poor's. Capacity to
pay interest and repay principal is extremely strong.

"AA. Debt rated 'AA' has a very strong capacity to pay interest and repay
principal and differs from the higher rated issues only in small degree.

"A. Debt rated 'A' has a strong  capacity to pay  interest  and repay  principal
although it is somewhat more  susceptible  to the adverse  effects of changes in
circumstances and economic conditions than debt in higher rated categories.

"BBB. Debt rated 'BBB' is regarded as having  adequate  capacity to pay interest
and  repay  principal.   Whereas  it  normally  exhibits   adequate   protection
parameters,  adverse  economic  conditions  or changing  circumstances  are more
likely to lead to a weakened  capacity to pay interest and repay  principal  for
debt in this category than in higher rated categories."

Debt rated "BB," or "B," is regarded,  on balance, as predominantly  speculative
with  respect to the  issuer's  capacity to pay  interest  and pay  principal in
accordance with the terms of the obligation. "BB" indicates the lowest degree of
speculation  and "CC" the highest  degree of  speculation.  While such debt will
likely have some quality and protective characteristics, these may be outweighed
by large uncertainties or major risk exposures to adverse conditions.

Unrated.  This  indicates  that no  rating  has been  requested,  that  there is
insufficient  information  on which to base a rating,  or that Standard & Poor's
does not rate a particular type of obligation as a matter of policy.

COMMERCIAL PAPER RATINGS

Moody's Commercial Paper Ratings

Moody's  ratings for commercial  paper are opinions of the ability of issuers to
repay  punctually  promissory  obligations  not having an  original  maturity in
excess of nine months.  Moody's two highest  commercial paper rating  categories
are as follows:

"P-1 -- "Prime-1"  indicates the highest quality repayment capacity of the rated
issues.

"P-2 -- "Prime-2"  indicates that the issuer has a strong capacity for repayment
of short-term promissory obligations. Earnings trends and coverage ratios, while
sound,  will be more  subjective to variation.  Capitalization  characteristics,
while still  appropriate,  may be more  affected by external  conditions.  Ample
alternate liquidity is maintained."

Standard & Poor's Commercial Paper Ratings

Standard & Poor's  commercial  paper  ratings  are  current  assessments  of the
likelihood  of timely  payment of debts  having an original  maturity of no more
than 365 days.  Standard & Poor's two highest commercial paper rating categories
are as follows:

"A-1 -- This  designation  indicates that the degree of safety  regarding timely
payment is very strong.  Those issues determined to possess  overwhelming safety
characteristics will be denoted with a plus (+) sign designation.

"A-2 -- Capacity for timely payment on issues with this designation is strong.
However, the relative degree of safety is not as high as for issues designated
A-1."

                NOTES TO PRO FORMA COMBINED FINANCIAL STATEMENTS
                                  MAY 31, 1998



Pro forma  information is intended to provide  shareholders  of the John Hancock
Government Income Fund and John Hancock Sovereign U.S.  Government Income
Fund   with  information  about the impact of the proposed  merger by
indicating  how the merger might have affected  information  had the merger been
consummated as of May 31, 1997.

The pro forma  combined  statements  of assets and  liabilities  and  results of
operations as of May 31, 1998,  have been prepared to reflect the merger of JHGI
and JHSUGIF after giving effect to pro forma adjustments  described in the notes
listed below.

(a)       Acquisition by John Hancock  Government  Income Fund of all the assets
          of John Hancock Sovereign U.S.  Government Income Fund and issuance of
          John  Hancock  Government  Income  Fund  Class A and Class B shares in
          exchange  for  all of the  outstanding  Class A and  Class  B  shares,
          respectively, of John Hancock Sovereign U.S. Government Income Fund.

(b)       The investment advisory fee was adjusted to reflect the application of
          the fee structure which will be in effect for John Hancock  Government
          Income Fund: 0.650% of the fund's first $200 million average daily net
          asset value;  0.625% of the fund's next $300 million average daily net
          asset value;  and 0.600% of the fund's  average  daily net asset value
          over $500 million.

(c)       The 12b-1 fee was  adjusted  to  reflect  the  application  of the fee
          structure  which  will be in effect  for the John  Hancock  Government
          Income  Fund:  0.25% of Class A average  daily net assets and 1.00% of
          Class B average daily net assets.

(d)       The transfer agent fee for the Class A and Class B shares is the total
          of the  respective  individual  fund's  transfer  agent fees. The main
          criteria in  determining  the transfer agent fees for a specific class
          is the number of shareholder accounts.

(e)       The actual  expenses  incurred by the John Hancock  Government  Income
          Fund and John  Hancock  Sovereign  U. S.  Government  Income  Fund for
          various expenses included on a pro forma basis were reduced to reflect
          the estimated savings arising from the merger.

(f)       Represents the Adviser's  voluntary agreement to limit management fees
          to an annual rate of 0.50% of John Hancock Government Income Fund's 
          average daily net assets.

DEAR FELLOW SHAREHOLDERS:

During the last  decade,  investors  have  become  used to seeing  stock  market
returns averaging 15% or so each year. In the past three years, the stock market
has treated us to a record run, producing annual returns in excess of 20%.

After such a long and  remarkable  performance,  many began this year  wondering
what the market would do for an encore in 1998.  The answer so far has been more
of the same, even with the recent increase in volatility  caused by tremors from
Asia. This achievement continues to bolster many investors' convictions that the
market will produce these results  forever,  or, in the worst case,  that market
declines  will always be  short-lived.  While the economy  remains solid and the
environment  favorable,  history  and  reason  tell  us it's a  highly  unlikely
scenario.

This doesn't mean we know what the market will do next,  or that it's
riding  for a fall.  But  after  such a run,  even in this  "new  era" of strong
economic growth with low inflation, we believe it would be wise for investors to
set more realistic expectations. As we've said before, markets do indeed move in
two directions.  Over the long term, the market's  historical  results have been
more in the 10% per year range,  which is still a solid result,  considering  it
has been produced despite wars, depressions and other social upheavals along the
way.

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

In addition to adjusting, or at least re-examining, expectations, now could
also be a good time to review with your investment  professional how your assets
are  diversified,  perhaps  with an eye  toward  a more  conservative  approach.
Stocks, especially with their outsized gains of the last three years, might have
grown to  represent a larger  piece of your  portfolio  than you had  originally
intended,  given your  objectives,  time horizon and risk level. 

At John Hancock Funds,  our goal is to help you reach your financial  objectives
and maintain wealth.  One way we can do that is by helping you keep your feet on
the ground as you pursue your dreams.

Sincerely,


/s/Edward J. Boudreau, Jr.

              U.S. bond market rally ends, holding pattern begins

U.S. bonds marched to two different tunes this past year.  Throughout the summer
and fall of 1997, low inflation, weaker commodity prices and a shrinking deficit
pushed bond prices higher.  Asia's  currency and credit  problems,  which seemed
destined to slow U.S.  economic growth,  further fueled the bond market's rally.
As interest rates tumbled,  U.S.  Treasuries did especially well.  Yields on the
10-year  Treasury  fell to 5.74% by year end,  down from 6.66% on May 31,  1997.

Contrary  to  expectations,  the U.S.  economy  began  showing  signs of growing
strength by mid-January.  At the same time, prices were falling worldwide as the
effects  of Asia's  problems  reverberated  in markets  across  the  globe.  The
combination of these two opposing forces N a strong economy and global deflation
N kept the bond market from moving much in either  direction for the rest of the
winter and spring.  Yields on the 10-year  Treasury  bounced around between 5.4%
and 5.8% throughout this time. With little opportunity for price gains, "spread"
securities  with a yield  advantage  over  Treasuries N including  both mortgage
bonds and U.S. government agencies N became more attractive.

Fortunately, John Hancock Sovereign U.S. Government Income Fund was able to keep
pace with the market's changes. For the year ended May 31, 1998, the Fund's

Class A and Class B shares had total returns of 10.68% and 9.93%,  respectively,
at net  asset  value.  Keep in mind that your net  asset  value  return  will be
different  from this  performance  if you were not  invested in the Fund for the
entire period and did not reinvest all distributions. By comparison, the average
general U.S.  government income fund had a total return of 10.46%,  according to
Lipper Analytical  Services,  Inc.1 During the same period,  the Lehman Brothers
Government Bond Index returned 11.23%. For longer-term performance  information,
please see pages six and seven.  

Swapping  Treasuries  for  mortgage  bonds.  As
interest rates were falling,  the Fund benefited from its sizeable stake in U.S.
Treasuries.  By November,  Treasuries represented 47% of the Fund's net assets N
up from 18% six months earlier. After interest rates leveled off in mid-January,
however,  we decided to sell Treasuries and buy mortgage bonds, whose prices had
lagged  Treasuries.  By May,  we had cut our  Treasury  stake back to 40% of net
assets.  

Mortgage  bonds offer a yield  advantage over  Treasuries  because they
carry additional risks. With mortgage bonds, investors take on prepayment risk N
or the risk that homeowners  will prepay their  mortgages  before they're due so
they can  refinance  at  lower  rates.  When  interest  rates  are  falling  and
prepayments  are picking  up,  prices on mortgage  bonds  usually  increase at a
slower rate than Treasuries.  By February,  we were beginning to see good buying
opportunities.  We  focused on  30-year  GNMA  bonds with 7% coupons  (or stated
interest rates),  as well as 15-year FNMA bonds with 6.5% coupons.  Our strategy
was to buy mortgage

U.S. Treasuries."

bonds  whose  coupons  were  below  those  where  most of the  prepayments  were
occurring  and above  those  where  most of the new  mortgage  bonds  were being
issued.  This protected the Fund somewhat from prepayments at existing  interest
rate  levels,  while  giving us the  advantage  of added  income.  As the spring
progressed  and  prepayments  began to ease off,  mortgage bonds did better than
Treasuries.  

At the same  time,  we held on to our 19%  stake in  collateralized
mortgage obligations (CMOs). These are special mortgage securities that take the
cash flows from  mortgage  pools and separate them into  different  classes with
varied  maturities and prepayment  risks.  Our longer-term  CMOs,  which did not
carry  much  prepayment  risk,  helped  generate  added  income  for  the  Fund.
Unfortunately, our shorter-term CMOs weakened as prepayments picked up. The Fund
ended the period with a 58% stake in mortgages,  up from 45% six months earlier.


We also kept our duration steady at 5.4 years. Duration measures how sensitive a
bond's price is to changes in interest rates. The longer a bond's duration,  the
more its price  will rise as  interest  rates fall N or fall as  interest  rates
rise.  A  longer-than-average  duration  worked well for much of the period when

interest  rates were falling.  With  hindsight,  we might have  benefited from a
shorter  duration  in January,  once rates  stabilized.  Since we  expected  the
economy to moderate and rates to fall further, however, we decided to sit tight.


Cautious  optimism ahead For the foreseeable  future, we plan to keep the Fund's
duration  long.  Once we see definite  signs that the economy is slowing,  we'll
lengthen  duration  further to take advantage of a possible  decline in interest
rates.  There are  several  reasons to expect U.S.  economic  growth to moderate
sometime before year end. The warm winter weather that pushed consumer  spending
to unsustainable  levels in the first quarter has passed.  Also during the first
quarter,  we saw a huge  build-up  in  inventory,  which will most  likely  slow
industrial  production going forward.  Finally,  as Asia's problems  deepen,  we
expect  U.S.  exports  to the region to slow and hurt  gross  domestic  product.
Weaker trends in one or more of these

"There are several reasons to expect U.S. economic growth to moderate..."

areas could signal the beginning of an economic slowdown.  We'll also be keeping
a close eye on corporate  earnings,  which have begun  growing at a slower pace.


Even in this uncertain environment,  the U.S. bond market remains attractive for
several  reasons.  Real  interest  rates N rates after  inflation N are still at
historically  high levels.  The longer inflation remains low, the more likely it
is that real interest rates will come down, sending bond prices up. In addition,
Treasury issuance has slowed thanks to a shrinking  deficit. A diminished supply
could help boost prices. On a broader scale, a stable democracy, strong economic
growth,  low  inflation  and bond yields that are higher than some other Western
industrialized  nations  also make the U.S.  bond  market  attractive.  All that
remains is for an economic  slowdown to lead to falling  interest  rates,  which
would in turn re-ignite the stalled bond market.

This commentary  reflects the views of the portfolio  manager through the end of
the Fund's period discussed in this report.  Of course,  the manager's views are
subject to change as market and other conditions  warrant.

A LOOK AT PERFORMANCE

The tables on the right show the cumulative total returns and the average annual
total returns for the John Hancock Sovereign U.S.  Government Income Fund. Total
return  measures the change in value of an investment  from the beginning to the
end of a period, assuming all distributions were reinvested. 

For Class A shares,  total return  figures  include a maximum  applicable  sales
charge of 4.5%. Class B performance reflects a maximum contingent deferred sales
charge (maximum 5% and declining to 0% over six years).

All figures  represent past  performance and are no guarantee of future results.
Keep in mind that the total  return and share  price of the  Fund's  investments
will fluctuate.  As a result,  your Fund's shares may be worth more or less than
their  original  cost,  depending  on when  you  sell  them.  Please  read  your
prospectus carefully before you invest or send money.

                          NOTES TO FINANCIAL STATEMENTS

           John Hancock Funds - Sovereign U.S. Government Income Fund

NOTE A -D
ACCOUNTING POLICIES

John Hancock Strategic Series (the "Trust") is an open-end management investment
company  registered under the Investment Company Act of 1940. The Trust consists
of two series:  John Hancock Sovereign U.S. Government Income Fund (the "Fund"),
and John  Hancock  Strategic  Income  Fund.  The  other  series  of the Trust is
reported in separate financial statements.  The investment objective of the Fund
is to provide as high a level of income as is consistent  with  long-term  total
return by investing in securities issued,  guaranteed or otherwise backed by the
United States government, its agencies or instrumentalities.

The Trustees have  authorized the issuance of multiple  classes of shares of the
Fund,  designated  as Class A and  Class B  shares.  The  shares  of each  class
represent an interest in the same  portfolio of investments of the Fund and have
equal rights to voting,  redemptions,  dividends,  and liquidation,  except that
certain  expenses,  subject  to the  approval  of the  Trustees,  may be applied
differently  to each class of shares in accordance  with current  regulations of
the  Securities  and  Exchange  Commission  and the  Internal  Revenue  Service.
Shareholders  of a class which bears  distribution  and service  expenses  under
terms of a distribution  plan have exclusive voting rights to that  distribution
plan.

Significant  accounting policies of the Fund are as follows:

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

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

INVESTMENT TRANSACTIONS 
Investment  transactions  are  recorded  as of the  date  of  purchase,  sale or
maturity.  Net realized gains and losses on sales of investments  are determined
on the identified cost basis.


FEDERAL INCOME TAXES 
The Fund's  policy is to comply with the  requirements  of the Internal  Revenue
Code that are applicable to regulated investment companies and to distribute all
of its taxable income,  including any net realized gain on  investments,  to its
shareholders.  Therefore,  no federal  income tax  provision  is  required.  For
federal  income  tax  purposes,   the  Fund  has  $44,710,231  of  capital  loss
carryforwards available, to the extent provided by regulations, to offset future
net realized  capital  gains.  If such  carryforwards  are used by the Fund,  no
capital gains  distribution will be made. The  carryforwards  expire as follows:
May  31,  2002 N  $12,665,411,  May  31,  2003 N  $26,193,155,  May  31,  2004 N
$3,597,046  and May 31,  2005 N  $2,254,619.  The Fund's tax year end is May 31.
Expired capital loss  carryforwards  are  reclassified to capital paid-in in the
year of expiration. Additionally, net capital losses of $266,692 attributable to
security  transactions incurred after October 31, 1997 are treated as arising on
the first day (June 1, 1998) of the Fund's next taxable year.

DIVIDENDS, INTEREST AND DISTRIBUTIONS  
Dividend income on investment  securities is recorded on the  ex-dividend  date.
Interest income on investment securities is recorded on the accrual basis.

The Fund records all  distributions to shareholders  from net investment  income
and realized gains on the ex-dividend date. Such distributions are determined in
conformity with income tax regulations, which may differ from generally accepted
accounting principles.  Dividends paid by the Fund with respect to each class of
shares will be  calculated  in the same manner,  at the same time and will be in
the  same  amount,  except  for the  effect  of  expenses  that  may be  applied
differently to each class.









DISCOUNT  ON  SECURITIES  

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


                                       14

                          NOTES TO FINANCIAL STATEMENTS

           John Hancock Funds - Sovereign U.S. Government Income Fund

Revenue  Code.  

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

USE OF ESTIMATES 
The  preparation  of these  financial  statements in accordance  with  generally
accepted  accounting  principles  incorporates  estimates  made by management in
determining the reported amounts of assets,  liabilities,  revenues and expenses
of the Fund. Actual results could differ from these estimates.

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

BANK BORROWINGS 
The Fund is  permitted  to have  bank  borrowings  for  temporary  or  emergency
purposes,  including the meeting of redemption  requests  that  otherwise  might
require the untimely disposition of securities. These agreements enable the Fund
to  participate  with other funds  managed by the Adviser in unsecured  lines of
credit with banks which  permit  borrowings  up to $800  million,  collectively.
Interest  is charged to each fund,  based on its  borrowing,  at a rate equal to
0.50% over the Fed Funds Rate. In addition,  a commitment  fee, at rates ranging
from 0.070% to 0.075% per annum based on the average daily unused portion of the
line of credit,  is allocated  among the  participating  funds.  The Fund had no
borrowing activity for the year ended May 31, 1998.

FINANCIAL  FUTURES  CONTRACTS  
The Fund may buy and sell  financial  futures  contracts  to hedge  against  the
effects of  fluctuations in interest rates and other market  conditions.  Buying
futures  tends to increase  the Fund's  exposure to the  underlying  instrument.
Selling  futures  tends  to  decrease  the  FundOs  exposure  to the  underlying
instrument or hedge other Fund  instruments.  At the time the Fund enters into a
financial futures contract,  it will be required to deposit with its custodian a
specified  amount  of cash or U.S.  government  securities,  known  as  "initial
margin,"  equal to a certain  percentage of the value of the  financial  futures
contract being traded.  Each day, the futures contract is valued at the official
settlement price on the board of trade or U.S.  commodities exchange on which it
trades. Subsequent payments, known as "variation margin," to and from the broker
are made on a daily basis as the market price of the financial  futures contract
fluctuates.  Daily  variation  margin  adjustments,  arising  from this "mark to
market,"  will be recorded by the Fund as unrealized  gains or losses. 

When the  contracts  are closed,  the Fund  recognizes a gain or loss.  Risks of
entering into futures  contracts  include the  possibility  that there may be an
illiquid  market  and/or  that a change  in the value of the  contracts  may not
correlate with changes in the value of the underlying  securities.  In addition,
the Fund could be prevented  from  opening or realizing  the benefits of closing
out  futures  positions  because  of  position  limits or limits on daily  price
fluctuation imposed by an exchange.

For federal income tax purposes, the amount,  character and timing of the Fund's
gains and/or losses can be affected as a result of futures contracts.

At May 31, 1998 there were the following  open positions in
financial futures contracts:

At May 31, 1998,  the Fund had  deposited in a segregated  account  $620,000 par
value of U.S.  Treasury Bond,  9.25%,  02-15-16 to cover margin  requirements on
open financial futures contracts.

OPTIONS
Listed  options will be valued at the last quoted sales price on the exchange on
which they are primarily traded.  Purchased put or call over-the-counter options
will be valued at the average of the "bid" prices  obtained from two independent
brokers.  Written  put or call  over-the-counter  options  will be valued at the
average of the "asked" prices  obtained from two independent  brokers.  Upon the
writing of a

call or put option, an amount equal to the premium received by the Fund will be
included  in  the  Statement  of  Assets  and   Liabilities   as  an  asset  and
corresponding liability. The amount of the liability will be subsequently marked
to market to reflect the current  market value of the written  option.  

The Fund may use option  contracts to manage its  exposure to the stock  market.
Writing puts and buying  calls will tend to increase the Fund's  exposure to the
underlying  instrument  and buying puts and writing  calls will tend to decrease
the  Fund's  exposure  to  the  underlying  instrument,   or  hedge  other  Fund
investments.

The maximum  exposure to loss for any  purchased  options will be limited to the
premium  initially  paid  for the  option.  In all  other  cases,  the  face (or
"notional")  amount of each contract at value will reflect the maximum  exposure
of the Fund in these  contracts,  but the actual exposure will be limited to the
change in value of the contract over the period the contract remains open.

Risks may also arise if counterparties do not perform under the contract's terms
("credit  risk"),  or if  the  Fund  is  unable  to  offset  a  contract  with a
counterparty on a timely basis ("liquidity risk").  Exchange-traded options have
minimal credit risk as the exchanges act as  counterparties to each transaction,
and only present liquidity risk in highly unusual market conditions. To minimize
credit and liquidity risks in over-the-counter  option contracts,  the Fund will
continuously monitor the creditworthiness of all its counterparties.

At any particular time, except for purchased options,  market or credit risk may
involve amounts in excess of those reflected in the Fund's period-end  Statement
of Assets and  Liabilities.  There were no written option  transactions  for the
year ended May 31, 1998.

NOTE B - MANAGEMENT FEE AND  TRANSACTIONS  WITH AFFILIATES
AND OTHERS 
Under  the  present  investment  management  contract,  the Fund  pays a monthly
management fee to the Adviser for a continuous investment program equivalent, on
an annual basis, to the sum of (a) 0.50% of the first $500,000,000 of the Fund's
average  daily net asset value,  and (b) 0.45% of the Fund's  average  daily net
asset value in excess of $500,000,000.

John Hancock Funds, Inc. ("JH Funds"), a wholly owned subsidiary of the Adviser,
acts as a distributor  for shares of the Fund.  For the year ended May 31, 1998,
net sales  charges  received on sales of Class A shares of the Fund  amounted to
$204,425.   Of  this  amount,   $24,018  was  retained  and  used  for  printing
prospectuses,  advertising,  sales literature,  and other purposes,  $40,686 was
paid as sales commissions to unrelated  broker-dealers  and $139,721 was paid as
sales  commissions  to  sales  personnel  of  John  Hancock  Distributors,  Inc.
("Distributors"),  a related broker-dealer.  The Adviser's indirect parent, John
Hancock  Mutual  Life  Insurance  Company  ("JHMLICo"),  is  the  indirect  sole
shareholder of Distributors.

Class B shares which are redeemed  within six years of purchase  will be subject
to a contingent  deferred sales charge  ("CDSC") at declining rates beginning at
5.00% of the lesser of the current market value at the time of redemption or the
original purchase cost of the shares being redeemed.  Proceeds from the CDSC are
paid to JH Funds and are used in whole or in part to  defray  its  expenses  for
providing  distribution related services to the Fund in connection with the sale
of Class B shares. For the year ended May 31, 1998 the contingent deferred sales
charges received by JH Funds amounted to $201,485.

In  addition,  to  reimburse  JH  Funds  for the  services  it  provides  as the
distributor of shares of the Fund, the Fund has adopted  Distribution Plans with
respect  to Class A and Class B  pursuant  to Rule  12b-1  under the  Investment
Company Act of 1940.  Accordingly,  the Fund will make  payments to JH Funds for
distribution  and service  expenses,  at an annual  rate not to exceed  0.30% of
Class A average  daily net assets and 1.00% of Class B average  daily net assets
to reimburse JH Funds for its distribution and service costs. Up to a maximum of
0.25% of such  payments may be service  fees as defined by the amended  Rules of
Fair  Practice of the National  Association  of  Securities  Dealers.  Under the
amended  Rules of Fair  Practice,  curtailment  of a portion of the Fund's 12b-1
payments could occur under certain circumstances.

The Fund has a transfer agent agreement with John Hancock  Signature  Services,
Inc.  ("Signature  Services"),  an indirect subsidiary of JHMLICo. The Fund pays
transfer agent fees based on the

                                       16

number of shareholder accounts and certain out-of-pocket  expenses. 

The  Fund has an  agreement  with  the  Adviser  to  perform  necessary  tax and
financial management services for the Fund. The compensation for the year was at
an annual rate of less than 0.02% of the average net assets of the Fund.

Mr. Edward J. Boudreau, Jr., Ms. Anne C. Hodsdon and Mr. Richard S. Scipione are
trustees  and/or  officers  of the  Adviser  and/or its  affiliates,  as well as
Trustees of the Fund. The compensation of unaffiliated  Trustees is borne by the
Fund.  The  unaffiliated  Trustees  may  elect to defer for tax  purposes  their
receipt of this  compensation  under the John  Hancock  Group of Funds  Deferred
Compensation  Plan. The Fund makes investments into other John Hancock funds, as
applicable, to cover its liability for the deferred compensation. Investments to
cover the Fund's  deferred  compensation  liability  are  recorded on the Fund's
books as an other asset.  The deferred  compensation  liability  and the related
other  asset are always  equal and are  marked to market on a periodic  basis to
reflect any income earned by the investment as well as any  unrealized  gains or
losses.  At  May  31,  1998,  the  Fund's  investments  to  cover  the  deferred
compensation liability had unrealized appreciation of $2,740.

NOTE C - INVESTMENT TRANSACTIONS 

Purchases and proceeds  from sales and  maturities  of  obligations  of the U.S.
government and its agencies,  other than short-term securities,  during the year
ended May 31, 1998 aggregated $574,229,515 and $618,363,551, respectively.

The cost of investments  owned at May 31, 1998  (including the joint  repurchase
agreement) for federal income tax purposes was  $352,651,873.  Gross  unrealized
appreciation  and  depreciation  of  investments   aggregated   $12,405,064  and
$1,539,164,   respectively,   resulting  in  net  unrealized   appreciation   of
$10,865,900.

NOTE D -
RECLASSIFICATIONS OF ACCOUNTS

During the year ended May 31, 1998, the Fund has reclassified amounts to reflect
an increase  in  accumulated  net  realized  loss on  investments  of $2,956,  a
decrease in  distributions  in excess of net  investment  income of $4,159 and a
decrease in capital paid-in of $1,203.  This represents the amount  necessary to
report these balances on a tax basis,  excluding certain temporary  differences,
as of May 31, 1998. Additional adjustments may be needed in subsequent reporting
periods. These reclassifications, which have no impact on the net asset value of
the Fund, are primarily  attributable to certain  differences in the computation
of  distributable  income and  capital  gains  under  federal  tax rules  versus
generally accepted accounting principles.

REPORT OF INDEPENDENT ACCOUNTANTS

To the Shareholders of John Hancock  Sovereign U.S.  Government  Income Fund and
the Trustees of John Hancock Strategic Series

In our opinion, the accompanying statement of assets and liabilities,  including
the schedule of  investments,  and the related  statements of operations  and of
changes  in net assets  and the  financial  highlights  present  fairly,  in all
material  respects,  the  financial  position  of John  Hancock  Sovereign  U.S.
Government  Income Fund (the  "Fund") (a  portfolio  of John  Hancock  Strategic
Series) at May 31, 1998, and the results of its  operations,  the changes in its
net assets and the financial highlights for the periods indicated, in conformity
with generally accepted accounting  principles.  These financial  statements and
financial highlights  (hereafter referred to as "financial  statements") are the
responsibility  of the Fund's  management;  our  responsibility is to express an
opinion on these  financial  statements  based on our audits.  We conducted  our
audits of these  financial  statements in  accordance  with  generally  accepted
auditing  standards  which  require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement.  An audit includes examining, on a test basis, evidence supporting
the  amounts  and  disclosures  in  the  financial  statements,   assessing  the
accounting principles used and the significant estimates made by management, and
evaluating the overall  financial  statement  presentation.  We believe that our
audits,   which  included   confirmation  of  securities  at  May  31,  1998  by
correspondence  with the custodian and brokers,  provide a reasonable  basis for
the opinion expressed above.

and that, in determining any liability  under the 1933 Act, each  post-effective
amendment shall be deemed to be a new registration  statement for the securities
offered therein, and the offering of the securities at that time shall be deemed
to be the initial bona fide offering of them.

Ladies and Gentlemen:

In connection  with the filing of a registration  statement under the Securities
Act of 1933, as amended (the "Act"), on Form N-14, with respect to the shares of
beneficial  interest of John  Hancock  Government  Income Fund (the  "Fund"),  a
series of John Hancock Bond Trust (the "Trust"), a Massachusetts business trust,
it is the opinion of the  undersigned  that these  shares when  issued,  will be
legally issued, fully paid and non-assessable.

In  connection  with this opinion it should be noted that the Trust is an entity
of  the  type  generally  known  as  a  "Massachusetts  business  trust."  Under
Massachusetts  law,  shareholders of a Massachusetts  business trust may be held
personally  liable  for the  obligations  of the  trust.  However,  the  Trust's
Declaration  of Trust  disclaims  shareholder  liability for  obligations of the
Trust and indemnifies any shareholder of the Fund, with this  indemnification to
be paid solely out of the assets of the Fund. Therefore,  the shareholder's risk
is limited to  circumstances in which the assets of the Fund are insufficient to
meet the obligations asserted against the Fund's assets.

The  undersigned  hereby  consents to the filing of a copy of this opinion as an
exhibit to the Trust's  registration  statement on Form N-14 with the Securities
and Exchange Commission.

Sincerely,

/s/ Theresa Apruzzese

Dear Members of the Boards of Trustees:

         You have  requested  our  opinion  regarding  the  federal  income  tax
consequences  described  below of the  acquisition  by John  Hancock  Government
Income Fund  ("Acquiring  Fund"), a series of John Hancock Bond Trust ("Trust"),
of all of the assets of John  Hancock  Sovereign  U.S.  Government  Income  Fund
("Acquired  Fund"), a series of John Hancock  Strategic Series ("Series Trust"),
in  exchange  solely  for (i) the  assumption  by  Acquiring  Fund of all of the
liabilities of Acquired Fund and (ii) the issuance of Class A and Class B voting
shares of beneficial interest of Acquiring Fund (the "Acquiring Fund Shares") to
Acquired Fund,  followed by the distribution by Acquired Fund, in liquidation of
Acquired Fund, of the Acquiring Fund Shares to the shareholders of Acquired Fund
and the termination of Acquired Fund (the foregoing  together  constituting  the
"reorganization" or the "transaction").

         In rendering  this opinion,  we have examined and relied upon the facts
stated and  representations  made in (i) the combined  prospectus  for Acquiring

1998,  (ii) the  statement of  additional  information  for  Acquiring  Fund and
another John  Hancock  mutual fund,  dated May 1, 1998,  (iii) the  statement of
additional  information for Acquired Fund, dated May 1, 1998, (iv) the Notice of
Meeting of  Shareholders  Scheduled  for November 11, 1998 and the  accompanying

1998 (the "Proxy Statement"), (v) the Agreement and Plan of Reorganization, made
August 10, 1998,  between  Acquiring  Fund and Acquired Fund (the  "Agreement"),
(vi) the  representation  letters on behalf of Acquiring  Fund and Acquired Fund
referred to below and (vii) such other documents as we deemed appropriate.

         In our  examination of documents,  we have assumed the  authenticity of
original documents,  the accuracy of copies, the genuineness of signatures,  and
the legal  capacity  of  signatories.  We have  assumed  that all parties to the
Agreement have acted and will act in accordance  with the terms of the Agreement
and all other  documents  relating to the  transaction  and that the transaction
will be  consummated  pursuant  to the  terms  and  conditions  set forth in the
Agreement  without the waiver or  modification of any such terms and conditions.
Furthermore,   we  have  assumed  that  all  representations  contained  in  the
Agreement,  as well as those  representations  contained  in the  representation
letters  referred to below are,  on the date  hereof,  true and  complete in all
material  respects,  and that any  representation  made in any of the  documents
referred  to  herein  "to the best of the  knowledge  and  belief"  (or  similar
qualification) of any person or party is correct without such qualification.  We
have not  attempted to verify  independently  such  representations,  but in the
course of our representation, nothing has come to our attention that would cause
us to question the accuracy thereof.

         The conclusions  expressed herein represent our judgment  regarding the
proper treatment of certain aspects of the transaction affecting Acquiring Fund,
Acquired Fund and the shareholders of Acquired Fund on the basis of our analysis
of the  Internal  Revenue  Code of 1986,  as  amended  (the  "Code"),  case law,
Treasury  regulations and the rulings and other  pronouncements  of the Internal
Revenue  Service  (the  "Service")  which  exist at the  time  this  opinion  is
rendered. Such authorities are subject to prospective or retroactive change, and
we do not undertake  any  responsibility  to advise you of any such change.  Our
opinion  represents  our best  judgment  regarding  how a court would  decide if
presented with the issues  addressed  herein and is not binding upon the Service
or any court.  Moreover,  our  opinion  does not provide  any  assurance  that a
position taken in reliance on such opinion will not be challenged by the Service
and does not constitute any representation or warranty that such position, if so
challenged, will not be rejected by a court.

         This opinion  addresses only the specific  United States federal income
tax  consequences of the  transaction set forth below,  and does not address any
other federal,  state, local, or foreign income, estate, gift, transfer,  sales,
or other tax  consequences  that may result  from the  transaction  or any other
transaction.

                                      FACTS

         We  understand  that  the  facts  relating  to the  transaction  are as
described hereinafter.

         Acquiring Fund is a series of Trust, a business trust established under
the laws of The Commonwealth of Massachusetts in 1984. Trust is registered as an
open-end investment company under the Investment Company Act of 1940, as amended
(the  "1940  Act").  Acquiring  Fund was  converted  from a series of a Maryland
corporation  to a series  of Trust on  August  30,  1996 in a  transaction  that
qualified as a  reorganization  described in Section  368(a)(1)(F)  of the Code.
Prior to December 22, 1994, Acquiring Fund was known as Transamerica  Government
Income  Fund.  Acquiring  Fund and its  predecessors  have been  operating as an
investment  company since the inception of business in 1988.  Acquiring  Fund is
one of three  series of Trust.  Each series of Trust has assets and  liabilities
that are  separate  from those of each other series and is treated as a separate
corporation and regulated investment company under Section 851(h) of the Code.

         The  investment  objective of Acquiring  Fund is to seek to earn a high
level of current income, consistent with preservation of capital. Acquiring Fund
pursues  this  objective by investing  primarily in U.S.  Government  and agency
securities and seeks stability of share price as a secondary goal.  Under normal
circumstances,  Acquiring  Fund invests at least 80% of its assets in securities
that are  issued,  or  guaranteed  as to  principal  and  interest,  by the U.S.
Government  and  its  agencies  or  instrumentalities,  as  well  as  repurchase
agreements and forward commitments involving these securities.

         Acquired Fund is a series of Series Trust, a business trust established
under the laws of The  Commonwealth of  Massachusetts  in 1986.  Series Trust is
registered as an open-end  investment  company under the 1940 Act. Acquired Fund
was  converted  from a series of a business  trust  known as Freedom  Investment
Trust to a series  of Series  Trust on August  30,  1996 in a  transaction  that
qualified as a  reorganization  described in Section  368(a)(1)(F)  of the Code.
Acquired Fund and its predecessor  have been operating as an investment  company
since the  inception of business in 1986.  Acquired Fund is one of two series of
Series Trust.  Each series of Series Trust has assets and  liabilities  that are
separate from those of the other series and is treated as a separate corporation
and regulated investment company under Section 851(h) of the Code.

         The investment objective of Acquired Fund is to seek to provide as high
a level of income as is consistent  with long-term  total return.  Acquired Fund
pursues  this  objective by investing  in U.S.  Government  and U.S.  Government
agency securities.  Under normal  circumstances,  Acquired Fund invests at least
65% of its assets in securities  that are issued,  or guaranteed as to principal

and  interest,  by the U.S.  Government  and its agencies or  instrumentalities.
Acquired  Fund may also invest in  investment-grade  short-term  securities  and
engage in derivatives, leverage, and other investment practices.

         The steps comprising the reorganization, as set forth in the Agreement,
are as follows:

         (i) Acquired  Fund will  transfer to  Acquiring  Fund all of its assets
(consisting,  without  limitation,  of  portfolio  securities  and  instruments,
dividend and interest  receivables,  cash and other assets). In exchange for the
assets  transferred to it, Acquiring Fund will (A) assume all of the liabilities
of  Acquired  Fund  (comprising  all of its known and  unknown  liabilities  and
referred  to  hereinafter  as the  "Acquired  Fund  Liabilities")  and (B) issue
Acquiring  Fund Shares to Acquired  Fund that have an aggregate  net asset value
equal to the value of the assets transferred to Acquiring Fund by Acquired Fund,
less the value of the Acquired Fund Liabilities assumed by Acquiring Fund.

         (ii)  Promptly  after the  transfer  of its assets to  Acquiring  Fund,
Acquired  Fund will  distribute  in  liquidation  the  Acquiring  Fund Shares it
receives in the exchange to Acquired Fund  shareholders pro rata in exchange for
their  surrender  of their  shares  of  beneficial  interest  of  Acquired  Fund
("Acquired Fund Shares").  In these  exchanges,  holders of Acquired Fund Shares
designated as Class A ("Class A Acquired  Fund  Shares") will receive  Acquiring
Fund Shares designated as Class A ("Class A Acquiring Fund Shares"), and holders
of Acquired  Fund Shares  designated as Class B ("Class B Acquired Fund Shares")
will receive  Acquiring  Fund Shares  designated  as Class B ("Class B Acquiring
Fund Shares").

         (iii) After such exchanges, liquidation and distribution, the existence
of Acquired Fund will be promptly  terminated in accordance  with  Massachusetts
law.

         The Agreement and the transactions  contemplated  thereby were approved
by the Board of Trustees of Trust,  on behalf of  Acquiring  Fund,  at a meeting
held on ________________, 1998. Acquiring Fund shareholders are not required and
were not asked to approve the  transaction.  The Agreement and the  transactions
contemplated  thereby were approved by the Board of Trustees of Series Trust, on
behalf of Acquired Fund, at a meeting held on  ______________,  1998, subject to
the approval of Acquired Fund shareholders.  Acquired Fund shareholders approved
the transaction at a meeting held on November 11, 1998.

         Massachusetts law does not provide dissenters' rights for Acquired Fund

shareholders  in  the  transaction.  Additionally,  it is  the  position  of the
Division of Investment Management of the Securities and Exchange Commission that
appraisal rights, in contexts such as the reorganization,  are inconsistent with
Rule 22c-1 under the 1940 Act and are  therefore  preempted and  invalidated  by
such rule. Consequently, Acquired Fund shareholders will not have dissenters' or
appraisal rights in the transaction.

         Our  opinions  set forth  below are  subject to the  following  factual
assumptions  being true and  correct  (including  statements  relating to future
actions and facts represented to be to the best knowledge of management, whether
or not known).  Authorized  representatives  of Acquiring Fund and Acquired Fund
have  represented  to us by letters  of even date  herewith  that the  following
assumptions are true and correct:

         (a)  Neither  Acquiring  Fund nor any  person  treated  as  related  to
Acquiring Fund under Treasury  Regulation Section  1.368-1(e)(3) has any plan or
intention  to redeem or otherwise  reacquire  any of the  Acquiring  Fund Shares
received by  shareholders  of  Acquired  Fund in the  transaction  except in the
ordinary  course of its business in connection with its legal  obligation  under
Section  22(e) of the 1940 Act  (which  obligation  is not in  connection  with,
modified in  connection  with,  or in any way related to the  transaction)  as a
registered open-end investment company to redeem its own shares.

         (b) After the  transaction,  Acquiring  Fund will continue the historic
business of Acquired Fund and will use all of the assets  acquired from Acquired
Fund,  which are Acquired  Fund's historic  business  assets,  i.e.,  assets not
acquired as part of or in  contemplation  of the  transaction,  in the  ordinary
course of a business.

         (c)  Acquiring  Fund  has no plan  or  intention  to sell or  otherwise
dispose of any assets of Acquired Fund acquired in the  transaction,  except for
dispositions  made in the ordinary  course of its business  (i.e.,  dispositions
resulting from investment  decisions made after the  reorganization on the basis
of investment  considerations  independent of the reorganization) or to maintain
its  qualification as a regulated  investment  company under Subchapter M of the
Code.

         (d) The shareholders of Acquiring Fund and the shareholders of Acquired
Fund will  bear  their  respective  expenses,  if any,  in  connection  with the
transaction.

         (e)  Acquiring  Fund and Acquired  Fund will each bear its own expenses
incurred in connection  with the  transaction.  Any liabilities of Acquired Fund
attributable  to such  expenses  that remain  unpaid on the closing  date of the
transaction   and  are  assumed  by  Acquiring  Fund  in  the   transaction  are
attributable to Acquired Fund's expenses that are solely and directly related to


<PAGE>

Page 6

the  transaction  in accordance  with the  guidelines  established  in Rev. Rul.
73-54, 1973-1 C.B. 187.

         (f) There is no indebtedness between Acquiring Fund and Acquired Fund.

         (g)  Acquired  Fund or its  predecessor  has elected to be treated as a
regulated  investment  company under  Subchapter M of the Code. Each of Acquired
Fund and its  predecessor  has qualified as a regulated  investment  company for
each taxable year since  inception,  and Acquired Fund qualifies as such for its
taxable year ending on the closing date of the transaction.

         (h) Acquiring Fund or a predecessor of Acquiring Fund has elected to be
treated as a regulated  investment  company under Subchapter M of the Code. Each
of Acquiring Fund and its predecessors  has qualified as a regulated  investment
company for each taxable year since  inception,  and Acquiring Fund qualifies as
such as of the date of the transaction.

         (i) Neither  Acquiring Fund nor Acquired Fund is under the jurisdiction
of a  court  in a Title  11 or  similar  case  within  the  meaning  of  Section
368(a)(3)(A) of the Code.

         (j)  Acquiring  Fund  does  not  own  and  neither  it  nor  any of its
predecessors has ever owned, directly or indirectly, any shares of Acquired Fund
or its predecessor.

         (k) Acquiring  Fund will not pay cash in lieu of  fractional  shares in
connection with the transaction.

         (l) As of the date of the  transaction,  the fair  market  value of the
Acquiring  Fund  Shares  issued to Acquired  Fund in exchange  for the assets of
Acquired Fund is  approximately  equal to the fair market value of the assets of
Acquired Fund received by Acquiring  Fund,  minus the value of the Acquired Fund
Liabilities  assumed by  Acquiring  Fund.  Acquiring  Fund will not  furnish any
consideration in connection with the acquisition of Acquired Fund's assets other
than the assumption of these Acquired Fund Liabilities and the issuance of these
Acquiring Fund Shares.

         (m)  Acquired  Fund  shareholders  will not be in control  (within  the
meaning of Sections  368(a)(2)(H)  and 304(c) of the Code,  which  provide  that
control  means  the  ownership  of shares  possessing  at least 50% of the total
combined  voting  power of all classes of shares that are entitled to vote or at
least 50% of the total value of shares of all classes) of  Acquiring  Fund after
the transaction.

         (n) The principal  business  purposes of the transaction are to combine


<PAGE>

Board of Trustees
John Hancock Strategic Series

December 4, 1998
Page 7

the  assets  of  Acquiring  Fund and  Acquired  Fund in order to  capitalize  on
economies  of scale in  expenses,  including  the  costs of  accounting,  legal,
transfer agency, insurance, custodial, and administrative services, to eliminate
the difficulty  experienced  by Acquired Fund in attracting  assets that results
from competition with Acquiring Fund (which has substantially similar investment
characteristics),   to  benefit  from  Acquiring   Fund's   anticipated   better
performance, and to increase diversification.

         (o) As of the date of the  transaction,  the fair  market  value of the
Class A Acquiring  Fund Shares  received by each holder of Class A Acquired Fund
Shares is  approximately  equal to the fair market value of the Class A Acquired
Fund Shares  surrendered by such  shareholder,  and the fair market value of the
Class B Acquiring  Fund Shares  received by each holder of Class B Acquired Fund
Shares is  approximately  equal to the fair market value of the Class B Acquired
Fund Shares  surrendered by such  shareholder.  No property other than Acquiring
Fund Shares will be distributed to shareholders of Acquired Fund in exchange for
their Acquired Fund Shares, nor will any such shareholder  receive cash or other
property as part of the transaction.

         (p) There is no plan or  intention  on the part of any  shareholder  of
Acquired Fund that owns beneficially 5% or more of the Acquired Fund Shares and,
to the best  knowledge  of  management  of  Acquired  Fund,  there is no plan or
intention  on the  part of the  remaining  shareholders  of  Acquired  Fund,  in
connection  with the  transaction,  to engage in any  transaction  with Acquired
Fund,  Acquiring  Fund,  or any person  treated as related to  Acquired  Fund or
Acquiring  Fund under the  standards  made  applicable  by  Treasury  Regulation
Section  1.368-1(e)(1)(i)  involving the sale, redemption,  exchange,  transfer,
pledge, or other  disposition  resulting in a direct or indirect transfer of the
risks of ownership  (a "Sale") of any of the Acquired  Fund Shares or any of the
Acquiring Fund Shares to be received in the  transaction  that,  considering all
Sales,  would reduce the  aggregate  ownership of the  Acquiring  Fund Shares by
former  Acquired Fund  shareholders  to a number of shares having a value, as of
the date of the  transaction,  of less than fifty  percent (50%) of the value of
all of the formerly  outstanding  Acquired Fund Shares as of the same date.  All
Sales involving shares of Acquired Fund and Acquiring Fund held by Acquired Fund
shareholders that have occurred or will occur in connection with the transaction
are taken into account for purposes of this representation. No such Sale that is
in connection with the transaction  has, to the best knowledge of the management
of Acquired Fund and Acquiring Fund, occurred on or prior to the Closing Date.

         (q) Acquired  Fund assets  transferred  to Acquiring  Fund  comprise at
least  ninety  percent  (90%) of the fair market  value of the net assets and at
least seventy percent (70%) of the fair market value of the gross assets held by
Acquired  Fund  immediately  prior  to the  transaction.  For  purposes  of this
representation,   amounts  used  by  Acquired   Fund  to  pay  its   outstanding


<PAGE>

Page 8

liabilities,   including   reorganization  expenses,  and  all  redemptions  and
distributions  (except for  redemptions in the ordinary  course of business upon
demand of a  shareholder  that  Acquired Fund is required to make as an open-end
investment company pursuant to Section 22(e) of the 1940 Act and regular, normal
dividends,   which  dividends  include  any  final  distribution  of  previously
undistributed  investment  company  taxable  income  and net  capital  gain  for
Acquired   Fund's  final  taxable  year  ending  on  the  closing  date  of  the
transaction)  made by Acquired Fund  immediately  preceding the  transaction are
taken into  account as assets of  Acquired  Fund held  immediately  prior to the
transaction.

         (r) The Acquired Fund  Liabilities  assumed by Acquiring  Fund plus the
liabilities,  if any, to which the transferred  assets are subject were incurred
by Acquired  Fund in the ordinary  course of its business or are expenses of the
transaction.

         (s) The fair market value of the Acquired  Fund assets  transferred  to
Acquiring  Fund  equals or  exceeds  the sum of the  Acquired  Fund  Liabilities
assumed by Acquiring  Fund and the amount of  liabilities,  if any, to which the
transferred assets are subject.

         (t)    Acquired    Fund    does   not   pay    compensation    to   any
shareholder-employee.

                                     OPINION

         On the basis of and subject to the  foregoing  and in reliance upon the
representations described above, we are of the opinion that:

         (a) The  acquisition by Acquiring Fund of all of the assets of Acquired
Fund solely in exchange for the  issuance of  Acquiring  Fund Shares to Acquired
Fund and the  assumption  of all of the Acquired Fund  Liabilities  by Acquiring
Fund,  followed by the distribution by Acquired Fund, in liquidation of Acquired
Fund,  of Acquiring  Fund Shares to Acquired Fund  shareholders  in exchange for
their Acquired Fund Shares and the termination of Acquired Fund, will constitute
a  "reorganization"  within the  meaning of  Section  368(a)(1)(C)  of the Code.
Acquiring  Fund and  Acquired  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 Acquired  Fund upon (i) the
transfer  of all of its assets to  Acquiring  Fund  solely in  exchange  for the
issuance of Acquiring  Fund Shares to Acquired Fund and the assumption of all of
the Acquired Fund  Liabilities  by Acquiring Fund and (ii) the  distribution  by
Acquired Fund of such Acquiring Fund Shares to the shareholders of Acquired Fund
(Sections 361(a) and 361(c) of the Code).

         (c) No gain or loss  will be  recognized  by  Acquiring  Fund  upon the
receipt of the assets of Acquired  Fund solely in exchange  for the  issuance of
Acquiring Fund Shares to Acquired Fund and the assumption of all of the Acquired
Fund Liabilities by Acquiring Fund (Section 1032(a) of the Code).

         (d) The basis of the assets of Acquired Fund acquired by Acquiring Fund
will be, in each instance, the same as the basis of those assets in the hands of
Acquired Fund immediately prior to the transfer (Section 362(b) of the Code).

         (e) The tax holding  period of the assets of Acquired Fund in the hands
of Acquiring Fund will, in each instance,  include  Acquired  Fund's tax holding
period for those assets (Section 1223(2) of the Code).

         (f) The  shareholders  of Acquired Fund will not recognize gain or loss
upon the exchange of all of their Acquired Fund Shares solely for Acquiring Fund
Shares as part of the transaction (Section 354(a)(1) of the Code).

         (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
Acquired Fund Shares  surrendered in exchange therefor (Section 358(a)(1) of the
Code).

         (h) The tax holding  period of the  Acquiring  Fund Shares  received by
Acquired Fund shareholders will include,  for each shareholder,  the tax holding
period for the Acquired Fund Shares surrendered in exchange  therefor,  provided
that the  Acquired  Fund Shares  were held as capital  assets on the date of the
exchange (Section 1223(1) of the Code).

         No opinion is expressed  or implied  regarding  the federal  income tax
consequences to Acquiring Fund,  Acquired Fund or Acquired Fund  shareholders of
any conditions existing at the time of, effects resulting from, or other aspects
of the transaction  except as expressly set forth above. This opinion may not be
relied upon  except  with  respect to the  consequences  specifically  discussed
herein  nor may it be  relied  upon by  persons  or  entities  to whom it is not
addressed, other than with our prior written consent.

                                            Very truly yours,


                                            Hale and Dorr LLP
