Dear Fellow Shareholder:

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

   
You may be aware that in addition to your Fund, John Hancock Funds offers
another growth-oriented fund, the John Hancock Growth Fund. Like your Fund, the
Growth Fund seeks long-term capital appreciation, but has built a larger asset
base than your Fund.
    

After careful consideration, your Fund's Trustees have unanimously recommended
merging your Fund into the John Hancock Growth Fund to offer you the same
investment objective with lower operating expenses. This proposed merger is
detailed in the enclosed proxy statement and summarized in the questions and
answers on the following page. I suggest you read both thoroughly before 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 call your
investment professional or your Customer Service Representative at
1-800-225-5291, Monday through Friday between 8:00 A.M. and 8:00 P.M. Eastern
Time. I thank you for your prompt vote on this matter.
    


                                                     Sincerely,

                                                     /s/ Edward J. Boudreau, Jr.

                                                     Edward J. Boudreau, Jr.
                                                     Chairman and CEO

Q: What are the benefits of merging the Discovery Fund into the Growth Fund?

   
A: With its larger asset base and more than 28-year history, the Growth Fund is
more widely established in the mutual fund marketplace than your Fund, which has
made it harder for your Fund to raise assets and reduce expenses. Your Trustees
firmly believe this merger will allow you to continue investing for long-term
capital appreciation at a lower expense.

The Growth Fund's larger asset base after the merger, $537 million compared with
Discovery's $116 million, will allow for operating expenses that are expected to
be lower than Discovery's. Following the merger, annual fees are projected to be
1.44% for Class A shareholders, down from 1.58%; and 2.14% for Class B
shareholders, down from 2.28%. 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 Growth Fund's strategy compare with that of the Discovery Fund?

   
A: Both Funds seek long-term capital appreciation through investments in stocks
that the management team believes have above-average earnings growth potential.
Although both funds may invest in companies of any size, the Growth Fund has
historically invested in larger, more established companies. While your Fund has
typically focused on stocks of emerging small and medium-sized companies, it
does invest selectively in large-company stocks when they present a particularly
attractive opportunity. We believe that the Growth Fund's increased
diversification and focus on larger, more mature companies should help us
deliver more consistent long-term performance with less risk.
    

<PAGE>

Q: How has the Growth Fund performed?

   
A: Although past performance does not necessarily guarantee future results, the
Growth Fund has been a steady performer over its more than 28-year history. The
Fund's Class A shares have posted average annual total returns of 9.04% over the
past year, 19.98% over the past three years, 14.73% over the past five years and
10.78% over the past ten years at public offering price as of June 30, 1997. The
Fund's Class B shares have posted an average annual total return of 8.93% over
the past year, 20.44% over the past three years and 12.37 since inception on
January 3, 1994.* To review the Growth Fund in greater detail, please refer to
the John Hancock Growth Funds prospectus and the Growth Fund's most recent
annual and semiannual reports, all of which are enclosed.
    

Q: How do I vote?

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

Q: How will the merger happen?

   
A: If the merger is approved, your Discovery Fund shares will be converted to
Growth Fund shares, using the Funds' net asset value share prices as of the
close of trading on December 5, 1997. This conversion will not affect the total
dollar value of your investment.
    

Q: Will the merger have tax consequences?

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


*Performance figures assume all distributions are reinvested and reflect a
maximum sales charge on Class A shares of 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.

A meeting of  shareholders  of your fund will be held at 101 Huntington  Avenue,

         of Growth Fund.  These shares would be distributed  proportionately  to
         you and the other  shareholders  of your fund.  Growth  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  17, 1997 are

Why Your Fund's Trustees are Recommending the Reorganization

The trustees of your fund believe that reorganizing your fund into a larger fund
with similar  investment  policies would enable the shareholders of your fund to
benefit from increased diversification, the ability to achieve better net prices
on  securities  trades and  economies of scale that could  contribute to a lower
expense ratio.  Therefore,  the trustees recommend that your fund's shareholders
vote FOR the reorganization.

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
months ended April 30, 1997 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 Tables

The board of trustees of another John  Hancock  fund,  John Hancock  Disciplined
Growth Fund, has recommended that  Disciplined  Growth Fund also reorganize into
Growth Fund. The reorganization of your fund with Growth Fund, however, does not
depend upon whether the reorganization involving Disciplined Growth Fund occurs.
Your  trustees do not expect the total  expenses paid by Growth Fund to increase
if both reorganizations do occur.

The next two expense  tables show the  hypothetical  ("pro  forma")  expenses of
Growth Fund  assuming  (1) that a  reorganization  with your fund,  but not John
Hancock  Disciplined  Growth  Fund,  occurred  on April  30,  1997 or (2) that a
reorganization  with both your fund and John  Hancock  Disciplined  Growth  Fund
occurred on April 30, 1997.  The expenses  shown in the table for Discovery Fund
and Growth Fund are based on fees and expenses incurred during the twelve months
ended April 30, 1997. Growth Fund's actual expenses after the reorganization may
be greater or less than those shown.  The  examples  contained in each pro forma
expense  table  show  what  you  would  pay  on  a  $1,000   investment  if  the
reorganization  had  occurred on April 30, 1997.  Each example  assumes that you
reinvested  all  dividends  and that the average  annual  return was 5%. The pro
forma examples are for comparison  purposes only and are not a representation of
Growth Fund's actual expenses or returns, either past or future.

(3)      Because of the 12b-1 fee, long-term shareholders may pay more than
         the equivalent of the maximum permitted front-end sales charge.
(4)      On September 9, 1997, the trustees of Growth Fund approved a
         reduction  in the advisory fee rates paid by Growth Fund to take affect
         on the reorganization date. After that date, Growth Fund's advisory fee
         rates will be identical  to the rates paid by your fund.  The pro forma
         management  fees in the tables have been  restated to reflect the lower
         fees.

The Reorganization

         o        The reorganization is scheduled to occur at 5:00 p.m., Eastern
                  Time, on December 5, 1997, but may occur on any later date
                  before June 1, 1998. Your fund will transfer all of its assets
                  to Growth Fund. Growth 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.

         o        Growth 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 Growth Fund.

         o        Growth 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 Growth Fund.

                                       15

         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.  If the reorganization had occurred on
April 30, 1997, Growth Fund's Class A and Class B expense ratios would have been
lower than your fund's current Class A and Class B expense ratios.

Your fund  pays,  and  Growth  Fund will pay after the  reorganization,  monthly
advisory  fees equal to the  following  annual  percentage  of average daily net
assets:

- ---------------------------------------------- ---------------- ----------------
                 Fund Asset
                 Breakpoints                      Discovery          Growth
- ---------------------------------------------- ---------------- ----------------
First $750 million                                  0.75%            0.75%
- ---------------------------------------------- ---------------- ----------------
Over $750 million                                   0.70%            0.70%
- ---------------------------------------------- ---------------- ----------------

Thus, at all asset  levels,  the advisory fee rates paid by your fund and Growth
Fund would be the same. However,  your fund's historical growth pattern suggests
that its asset size probably would not have increased  sufficiently  in the near
future to qualify for the 0.70% fee rate.  Combining the assets of your fund and
Growth Fund will  enable  Growth Fund to more  quickly  reach the fee  reduction
breakpoint.

In addition,  Growth  Fund's other  expenses of 0.36% , as well as its pro forma
other  expenses,  are  substantially  lower than your fund's  other  expenses of
0.53%.  Consequently,  Growth Fund's  annual Class A and Class B expense  ratios
(equal to 1.45% and 2.15%,  respectively,  of average net assets) are lower than
your fund's expense ratios (equal to 1.58% and 2.28%,  respectively,  of average
net assets). If the reorganization had occurred on April 30, 1997, Growth Fund's
pro  forma  Class A and  Class B  expense  ratios  (equal  to 1.45%  and  2.15%,
respectively, of average net assets) would also have been lower than your fund's
current expense ratios.

                       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:

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

                                       19

<PAGE>

         o        Growth 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 Growth Fund.

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

Reasons for the Proposed Reorganization

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

First,  that  Growth  Fund  is  more  widely  established  in  the  mutual  fund
marketplace, making it increasingly difficult to attract assets to your fund.

Second,  that Growth  Fund's  total  expenses  are lower than your fund's  total
expenses.  As a result  of the  reorganization,  shareholders  of your fund will
experience a reduction in the total amount of fees that they indirectly pay each
month.

Third,  that  shareholders  may be  better  served  by a fund  offering  greater
diversification.  To the extent that  combining  the funds' assets into a single
portfolio creates a larger asset base,  Growth Fund's  investment  portfolio can
achieve  greater  diversification  after the  reorganization  than is  currently
possible for either  fund.  Greater  diversification  is expected to benefit the
shareholders  of both funds  because it may reduce the negative  effect that the
adverse  performance  of any one  security  may have on the  performance  of the
entire portfolio.

Fourth,  that the Growth Fund shares received in the reorganization will provide
you with a similar  investment at a comparable or lower level of risk. The board
of trustees also considered the performance history of each fund.

Fifth,  that a combined fund offers economies of scale that are expected to lead
to better control over expenses than is possible for your fund. Both funds incur

                                       20

<PAGE>

substantial costs for accounting,  legal,  transfer agency services,  insurance,
and custodial and administrative services.

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

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

Comparative Fees and Expense Ratios

As  discussed  above in the  Summary,  at all asset levels the advisory fee rate
paid by your fund and  Growth  Fund  would be the  same.  However,  your  fund's
historical  growth pattern  suggests that its asset size probably would not have
increased  sufficiently  in the near  future to  qualify  for the fee  reduction
breakpoint. Combining the assets of your fund and Growth Fund will enable Growth
Fund to more quickly reach that fee reduction  breakpoint.  In addition,  Growth
Fund's other  expenses of 0.36%,  as well as its pro forma other  expenses,  are
substantially  lower than your fund's  other  expenses  of 0.53%.  Consequently,
Growth  Fund's  annual  Class A and Class B expense  ratios  (equal to 1.45% and
2.15%,  respectively,  of average net assets) are lower than your fund's expense
ratios (equal to 1.58% and 2.28%,  respectively,  of average net assets). If the
reorganization  had occurred on April 30, 1997,  Growth Fund's pro forma Class A
and Class B expense ratios (equal to 1.45% and 2.15%,  respectively,  of average
net assets) would also have been lower than your fund's current expense ratios.

Comparative Performance

The trustees also took into consideration the relative  performance of your fund
and  Growth  Fund.  As shown in the  table  below,  Growth  Fund has had  better
performance than your fund over all periods.

*Since inception.

Your fund  experienced a negative return during the one year period ending April
30, 1997.  The trustees  believe that Growth Fund's  ability to achieve  greater
diversification  will  provide  for  more  consistent  positive  returns.   This
conclusion is supported by the fact that all of Growth Fund's one,  three,  five
and ten year total return figures are positive.

Unreimbursed Distribution and Shareholder Service Expenses

The boards of trustees of your fund and Growth 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 Growth  Fund's Rule 12b-1 Plans.  However,  the maximum  amounts
payable  annually  under  Growth  Fund's  Rule 12b-1  Plans  (0.30% 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

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

Thus,  if the  reorganization  had taken place on April 30, 1997,  the pro forma
combined unreimbursed expenses of Growth Fund's Class A and Class B shares would
have been higher than if no reorganization  had occurred.  Nevertheless,  Growth
Fund's  assumption of your fund's  unreimbursed Rule 12b-1 expenses will have no
immediate  effect upon the payments  made under Growth  Fund's Rule 12b-1 Plans.
These  payments  will continue to be 0.30% and 1.00% of average daily net assets
attributable to Class A and Class B shares, respectively.

John Hancock Funds, Inc. hopes to recover unreimbursed distribution and
shareholder service expenses for Class B shares over an extended period of time.
However, if Growth 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"

                                       23

<PAGE>

                  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 Growth Fund as described
                  above or (2) the distribution by your fund of Growth Fund
                  shares to your fund's shareholders;

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

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

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

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

Additional Tax Considerations

As  of  October  31,  1996,  Discovery  Fund  had  capital  loss  carryovers  of
approximately  $981,469,   which  expire  on  October  31,  2004.  Capital  loss
carryovers  are used to reduce the amount of realized  capital gains that a fund
is required to distribute to its  shareholders in order to avoid paying taxes on
undistributed capital gain.

                                       24

<PAGE>

If the reorganization  occurs,  Growth Fund will be able to use Discovery Fund's
capital loss  carryovers to offset future  realized  capital  gains,  subject to
limitations  that may, in certain  circumstances,  result in the expiration of a
portion of these carryovers before they can be used.

Additional Terms of Agreement and Plan of Reorganization

Surrender  of Share  Certificates.  Shareholders  of your fund whose  shares are
represented by one or more share certificates should,  before the reorganization
date, either surrender their certificates to your fund or deliver to your fund a
lost certificate affidavit, in the form and accompanied by the surety bonds that
your fund may require  (collectively,  an  "Affidavit").  On the  reorganization
date, all certificates that have not been surrendered will be canceled,  will no
longer evidence  ownership of your fund's shares and will evidence  ownership of
Growth Fund shares.  Shareholders  may not redeem or transfer Growth Fund shares
received  in the  reorganization  until they have  surrendered  their fund share
certificates  or  delivered  an  Affidavit.  Growth  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 Growth 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 Growth Fund to consummate the reorganization is subject to the
satisfaction of certain conditions,  including your fund's performance of all of
its  obligations  under the  Agreement,  the  receipt of certain  documents  and
financial statements from your fund and the receipt of all consents,  orders and
permits necessary to consummate the reorganization (see Agreement, paragraph 7).

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

Termination  of  Agreement.  The board of trustees of either your fund or Growth
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

                                       25

<PAGE>

believes that proceeding with the reorganization would no longer be advisable.

Expenses  of the  Reorganization.  Growth  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 $158,907 in total.

                                 CAPITALIZATION

         The following  table sets forth the  capitalization  of each fund as of
April 30, 1997,  and the pro forma combined  capitalization  of both funds as if
the  reorganization  had  occurred on such date.  The table  reflects  pro forma
exchange ratios of approximately  0.5982 Class A Growth Fund shares being issued
for each Class A share of your fund and approximately 0.5859 Class B Growth Fund
shares being issued for each Class B share of your fund.  If the  reorganization
is consummated,  the actual exchange ratios on the reorganization  date may vary
from the  exchange  ratios  indicated  due to changes in the market value of the
portfolio  securities  of both Growth Fund and your fund between  April 30, 1997
and  the  reorganization  date,  changes  in the  amount  of  undistributed  net
investment  income and net realized  capital  gains of Growth Fund and your fund
during that period resulting from income and  distributions,  and changes in the
accrued liabilities of Growth Fund and your fund during the same period.

1 Assuming the  reorganization of Disciplined  Growth Fund into Growth Fund does
not occur. If the  reorganization of your fund only had taken place on April 30,
1997, your fund would have received 1,870,113 Class A shares and 3,760,175 Class
B shares of Growth Fund, which would have been available for distribution to the
shareholders of your fund.

                                       26

2 Assuming  the  reorganization  of  Disciplined  Growth  Fund into  Growth Fund
occurs.  If both  reorganizations  had taken place on April 30, 1997,  your fund
would have received  1,870,113  Class A shares and  3,760,175  Class B shares of
Growth  Fund,   which  would  have  been  available  for   distribution  to  the
shareholders of your fund.

It is impossible to predict how many Class A shares and Class B shares of Growth
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 Growth 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 Growth Fund,
including  the  independent  trustees,  approved the  reorganization.  They also
determined that the  reorganization was in the best interests of Growth Fund and
that the  interests  of Growth  Fund's  shareholders  would not be  diluted as a
result of the reorganization.

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




                        VOTING RIGHTS AND REQUIRED VOTE

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

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

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

Shares of your fund  represented in person or by proxy,  including  shares which
abstain  or do not vote  with  respect  to the  proposal,  will be  counted  for
purposes of determining  whether there is a quorum at the meeting.  Accordingly,
an abstention from voting has the same effect as a vote against the proposal.

However, if a broker or nominee holding shares in "street name" indicates on the
proxy  card  that  it  does  not  have  discretionary  authority  to vote on the
proposal,  those shares will not be  considered  present and entitled to vote on
the  proposal.  Thus,  a  "broker  non-vote"  has no  effect  on the  voting  in
determining  whether the proposal has been adopted in accordance with clause (1)
above,  if more  than  50% of the  outstanding  shares  (excluding  the  "broker
non-votes")  are present or  represented.  However,  for purposes of determining

                                       28

<PAGE>

whether the  proposal has been adopted in  accordance  with clause (2) above,  a
"broker  non-vote"  has the same effect as a vote against the  proposal  because
shares  represented  by a "broker  non-vote" are  considered  to be  outstanding
shares.

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

                       INFORMATION CONCERNING THE MEETING

Solicitation of Proxies

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

Revoking Proxies

A Discovery  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 STE 1000, Boston, Massachusetts 02217-1000, or

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

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

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



                                       29
<PAGE>

Outstanding Shares and Quorum

   
As of September 17, 1997, 2,945,751 Class A shares and 6,238,163 Class B shares
of beneficial interest of your fund were outstanding. Only shareholders of
record on September 17, 1997 (the "record date") are entitled to notice of and
to vote at the meeting. A majority of the outstanding shares of your fund that
are entitled to vote will be considered a quorum for the transaction of
business.
    

Other Business

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

Adjournments

If a quorum is not  present in person or by proxy at the time any session of the
meeting is called to order,  the persons named as proxies may vote those proxies
that have been  received to adjourn the meeting to a later date.  If a quorum is
present but there are not sufficient votes in favor of the proposal, the persons
named as proxies may propose one or more  adjournments  of the meeting to permit
further  solicitation of proxies  concerning the proposal.  Any adjournment will
require the affirmative  vote of a majority of your fund's shares at the session
of the meeting to be  adjourned.  If an  adjournment  of the meeting is proposed
because there are not  sufficient  votes in favor of the  proposal,  the persons
named as proxies  will vote those  proxies  favoring  the  proposal  in favor of
adjournment,  and will vote those  proxies  against the  reorganization  against
adjournment.

Telephone Voting

In addition to soliciting  proxies by mail,  by fax or in person,  your fund may
also arrange to have votes  recorded by  telephone by officers and  employees of
your fund or by personnel of the adviser or transfer agent. The telephone voting
procedure is designed to verify a shareholder's identity, to allow a shareholder
to  authorize  the  voting  of  shares  in  accordance  with  the  shareholder's
instructions  and to confirm  that the voting  instructions  have been  properly
recorded.  If these  procedures  were subject to a successful  legal  challenge,
these  telephone  votes would not be counted at the  meeting.  Your fund has not
obtained an opinion of counsel  about  telephone  voting,  but is currently  not
aware of any challenge.

         o        A shareholder will be called on a recorded line at the
                  telephone number in the fund's account records and will be

                                       30

<PAGE>

                  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

                                    EXHIBIT A

                      AGREEMENT AND PLAN OF REORGANIZATION

THIS AGREEMENT AND PLAN OF  REORGANIZATION  (the  "Agreement") is made this 22nd
day of September,  1997, by and between John Hancock Growth Fund (the "Acquiring
Fund"), a series of John Hancock Investment Trust III, a Massachusetts  business
trust (the "Trust II"), and John Hancock Discovery Fund (the "Acquired Fund"), a
series of John Hancock Investment Trust IV, 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 

                                      A-1

<PAGE>

     assumed by the Acquiring Fund, and (ii) delivery by the Acquiring Fund to
     the Acquired Fund, for distribution pro rata by the Acquired Fund to its
     shareholders in proportion to their respective ownership of Class A and/or
     Class B shares of beneficial interest of the Acquired Fund, as of the close
     of business on December 5, 1997 (the "Closing Date"), of a number of the
     Acquiring Fund Shares having an aggregate net asset value equal, in the
     case of each class of Acquiring Fund Shares, to the value of the assets,
     less such liabilities (herein referred to as the "net value of the assets")
     attributable to the applicable class, assumed, assigned and delivered, all
     determined as provided in Paragraph 2.1 hereof and as of a date and time as
     specified therein. Such transactions shall take place at the closing
     provided for in Paragraph 3.1 hereof (the "Closing"). All computations
     shall be provided by Investors Bank & Trust Company (the "Custodian"), as
     custodian and pricing agent for the Acquiring Fund and the Acquired Fund.

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

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

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

                                      A-2

<PAGE>

     certificates representing Acquiring Fund Shares in connection with such
     exchange.

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

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

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

1.8  Any reporting responsibility of the 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 

                                      A-3

<PAGE>

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

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

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

3.   CLOSING AND CLOSING DATE

3.1  The Closing Date shall be December 5, 1997 or such other date on or before
     June 30, 1998 as the parties may agree. The Closing shall be held as of
     5:00 p.m. at the offices of the Trust II and the Trust, 101 Huntington
     Avenue, Boston, Massachusetts 02199, or at such other time and/or place as
     the parties may agree.

3.2  Portfolio securities that are not held in book-entry form in the name of
     the Custodian as record holder for the Acquired Fund shall be presented by
     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 

                                      A-4

<PAGE>

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

3.3  In the event that on the Closing Date (a) the New York Stock Exchange shall
     be closed to trading or trading thereon shall be restricted or (b) trading
     or the reporting of trading on said Exchange or elsewhere shall be
     disrupted so that accurate appraisal of the value of the net assets of the
     Acquiring Fund or the Acquired Fund is impracticable, the Closing Date
     shall be postponed until the first business day after the day when trading
     shall have been fully resumed and reporting shall have been restored;
     provided that if trading shall not be fully resumed and reporting restored
     on or before June 30, 1998, this Agreement may be terminated by the
     Acquiring Fund or by the Acquired Fund upon the giving of written notice to
     the other party.

3.4  The Acquired Fund shall deliver at the Closing a list of the names,
     addresses, federal taxpayer identification numbers and backup withholding
     and nonresident alien withholding status of the Acquired Fund shareholders
     and the number of outstanding shares of each class of beneficial interest
     of the Acquired Fund owned by each such shareholder, all as of the close of
     business on the Closing Date, certified by its Treasurer, Secretary or
     other authorized officer (the "Shareholder List"). The Acquiring Fund shall
     issue and deliver to the Acquired Fund a confirmation evidencing the
     Acquiring Fund Shares to be credited on the Closing Date, or provide
     evidence satisfactory to the Acquired Fund that such Acquiring Fund Shares
     have been credited to the Acquired Fund's account on the books of the
     Acquiring Fund. At the Closing, each party shall deliver to the other such
     bills of sale, checks, assignments, stock certificates, receipts or other
     documents as such other party or its counsel may reasonably request.

4.1  The Trust on behalf of the Acquired Fund represents, warrants and covenants

          Acquired Fund is required to qualify to do business in any
          jurisdiction in which it is not so qualified or where failure to

          Trust has all necessary federal, state and local 

                                      A-5

          Fund is a diversified series of the Trust;

          Trust, as amended and restated (the "Trust's Declaration") or By-Laws
          or of any agreement, indenture, instrument, contract, lease or other

          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

          the statement of changes in net assets for the year ended July 31,
          1996, and the period from August 1, 1996 to October 31, 1996, and the

          business, or any incurrence by the Acquired Fund of indebtedness
          maturing more than one year from the date such indebtedness was

          paid so far as due, or provision shall have been made for the payment
          thereof, and to the best of the Acquired Fund's knowledge no such
          return is currently under audit and no assessment has been asserted

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

     (j)  The authorized capital of the Acquired Fund consists of an unlimited
          number of shares of beneficial interest, no par value. All issued and

          subscribe for or purchase any of its shares of beneficial interest,
          nor is there outstanding any security convertible into any of its
          shares of beneficial interest;

     (k)  At the Closing Date, the Acquired Fund will have good and marketable
          title to the assets to be transferred to the Acquiring Fund pursuant
          to Paragraph 1.1 hereof, and full right, power and authority to sell,

<PAGE>

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

     (l)  The execution, delivery and performance of this Agreement have been
          duly authorized by all necessary action on the part of the Trust on

          hereof (other than written information furnished by the Acquiring Fund
          for inclusion therein, as covered by the Acquiring Fund's warranty in

          shareholders and on the Closing Date, shall not contain any untrue
          statement of a material fact or omit to state a material fact required
          to be stated therein or necessary to make the statements therein, in

          contract, lease or other undertaking to which the Trust II or the
          Acquiring Fund is a party or by which the Trust II or the Acquiring
          Fund is bound;

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

     (g)  The unaudited statement of assets and liabilities, including the
          schedule of investments, of the Acquiring Fund as of April 30, 1997
          and the related statement of operations for the six months then ended,
          and the statement of changes in net assets for the year ended December
          31, 1995, and the period from January 1, 1996 to October 31, 1996, and
          the six months ended April 30, 1997 (copies of which have been
          furnished to the Acquired Fund) present fairly in all material
          respects the financial condition of the Acquiring Fund as of April 30,
          1997 and the results of its operations for the period then ended in
          accordance with generally accepted accounting principles consistently
          applied, and there were no known actual or contingent liabilities of
          the Acquiring Fund as of the respective dates thereof not disclosed
          therein;

     (h)  Since April 30, 1997, there has not been any material adverse change
          in the Acquiring Fund's financial condition, assets, liabilities or
          business other than changes occurring in the ordinary course of
          business, or any incurrence by the Trust II on behalf of the Acquiring
          Fund of indebtedness maturing more than one year from the date such
          indebtedness was incurred, except as disclosed to and accepted by the
          Acquired Fund;

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

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

                                      A-10

<PAGE>

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

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

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

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

          Shares to the Acquired Fund and the assumption of all of the Acquired
          Fund Liabilities by the Acquiring Fund, followed by the distribution
          by the Acquired Fund, in liquidation of the Acquired Fund, of
          Acquiring Fund Shares to the shareholders of the Acquired Fund in
          exchange for their shares of beneficial interest of the Acquired Fund
          and the termination of the Acquired Fund, will constitute a
          "reorganization" within the meaning of Section 368(a) of the Code, and

          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

          assumption of all of the Acquired Fund Liabilities by the Acquiring

          Fund Shares to the shareholders of the Acquired Fund;

     (c)  No gain or loss will be recognized by the Acquiring Fund upon the

          Fund;

                                      A-15

<PAGE>

     (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.

9.   BROKERAGE FEES AND EXPENSES

9.1  The Trust II on behalf of the Acquiring Fund, and the Trust on behalf of

Overview

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

GOAL OF THE GROWTH FUNDS

John Hancock growth funds seek long-term growth by investing primarily in common
stocks. 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   have longer time horizons
o   are willing to accept higher short-term risk along with higher potential
    long-term returns
o   want to diversify their portfolios
o   are seeking funds for the growth portion of an asset allocation portfolio
o   are investing for retirement or other goals that are many years in the
    future

Growth funds may NOT be appropriate if you:

o   are investing with a shorter time horizon in mind
o   are uncomfortable with an investment that will go up and down in value

THE MANAGEMENT FIRM

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

Disciplined Growth Fund

REGISTRANT NAME: JOHN HANCOCK INVESTMENT TRUST II
                                 TICKER SYMBOL   CLASS A: SVAAX   CLASS B: FEQVX
- --------------------------------------------------------------------------------

GOAL AND STRATEGY

[Clip art] The fund seeks long-term growth of capital. To pursue this goal, the
fund invests in established, growing companies that have demonstrated superior
earnings growth and stability. Under normal circumstances, the fund invests at
least 65% of assets in these companies, without concentration in any one
industry. The fund also looks for the following characteristics: 

o  predictability of earnings 
o  a low level of debt 
o  seasoned management 
o  a strong market position

Many of the fund's investments are in medium or large capitalization companies.
The fund invests for income as a secondary goal.

PORTFOLIO SECURITIES

[Clip art] The fund invests primarily in the common stocks of U.S. companies. It
may also invest in warrants, preferred stocks and convertible debt securities.

For liquidity and flexibility, the fund may place up to 15% of net assets in
cash or in investment-grade short-term securities. In abnormal market
conditions, it may invest up to 80% in these securities as a defensive tactic.
The fund also may invest in certain higher-risk securities, and may engage in
other investment practices.

RISK FACTORS

[Clip art] As with any growth fund, the value of your investment will fluctuate
in response to stock market movements.

To the extent that the fund invests in higher-risk securities, it takes on
additional risks that could adversely affect its performance. Before you invest,
please read "More about risk" starting on page 30.

PORTFOLIO MANAGEMENT

[Clip art] John F. Snyder III and Jere E. Estes are the leaders of the fund's
portfolio management team. Mr. Snyder is an executive vice president of the
adviser and has been a team member since July 1992. He has been an investment
manager since 1971. Mr. Estes has been a part of the fund's management team
since joining John Hancock in July 1992. He has been in the investment business
since 1967.

      calculated."

(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.

Discovery Fund

REGISTRANT NAME: JOHN HANCOCK INVESTMENT TRUST IV
                                 TICKER SYMBOL   CLASS A: FRDAX   CLASS B: FRDIX
- --------------------------------------------------------------------------------
GOAL AND STRATEGY

[Clip art] The fund seeks long-term capital appreciation. To pursue this goal,
the fund invests in companies that appear to offer superior growth prospects.
Under normal circumstances, the fund invests at least 65% of assets in these
companies. The fund looks for companies, including small- and medium-sized
companies, that have broad market opportunities and consistent or accelerating
earnings growth. These companies may:

o   occupy a profitable market niche
o   have products or technologies that are new, unique or proprietary
o   be in an industry that has a favorable long-term growth outlook
o   have a capable management team with a significant equity stake

These companies may be in a relatively early stage of development, but will
usually have established a record of profitability and a strong financial
position. The fund does not invest for income.

PORTFOLIO SECURITIES

[Clip art] The fund invests primarily in common stocks of U.S. companies and may
also invest in warrants, preferred stocks and investment-grade convertible debt
securities.

For liquidity and flexibility, the fund may place up to 15% of net assets in
cash or in investment-grade short-term securities. In abnormal market
conditions, it may invest up to 80% in these securities as a defensive tactic.
The fund may invest up to 25% of assets in foreign securities, which carry
additional risks. The fund also may invest in certain higher-risk securities,
and may engage in other investment practices.

RISK FACTORS

[Clip art] As with any growth fund, the value of your investment will fluctuate
in response to stock market movements. To the extent that the fund invests in
small- and medium-sized company stocks, foreign securities and other higher-risk
securities, it takes on additional risks that could adversely affect its
performance. The fund may experience higher volatility than many other types of
growth funds. Before you invest, please read "More about risk" starting on page
30.

PORTFOLIO MANAGEMENT

[Clip art] Bernice S. Behar, CFA, leader of the fund's portfolio management team
since March 1994, is a senior vice president of the adviser. She joined the
adviser in 1991 and has been in the investment business since 1986.

Emerging Growth Fund

REGISTRANT NAME: JOHN HANCOCK SERIES TRUST
                                     TICKER SYMBOL CLASS A: TAEMX CLASS B: TSEGX
- --------------------------------------------------------------------------------
GOAL AND STRATEGY

[Clip art] The fund seeks long-term capital appreciation. To pursue this goal,
the fund invests in emerging companies (market capitalization of less than $1
billion). Under normal circumstances, the fund invests at least 80% of assets in
a diversified portfolio of these companies. The fund looks for companies that
show rapid growth but are not yet widely recognized. The fund also may invest in
established companies that, because of new management, products or
opportunities, offer the possibility of accelerating earnings. The fund does not
invest for income.

PORTFOLIO SECURITIES

[Clip art] The fund invests primarily in the common stocks of U.S. and foreign
emerging growth companies, although it may invest up to 20% of assets in other
types of companies. The fund may also invest in warrants, preferred stocks and
investment-grade convertible debt securities.

For liquidity and flexibility, the fund may place up to 20% of assets in cash or
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 securities, and may engage in other investment
practices.

RISK FACTORS

[Clip art] As with any growth fund, the value of your investment will fluctuate
in response to stock market movements. Stocks of emerging growth companies carry
higher risks than stocks of larger companies. This is because emerging growth
companies:

o   may be in the early stages of development
o   may be dependent on a small number of products or services
o   may lack substantial capital reserves
o   do not have proven track records

In addition, stocks of emerging companies are often traded in low volumes, which
can increase market and liquidity risks. Before you invest, please read "More
about risk" starting on page 30.

PORTFOLIO MANAGEMENT

[Clip art] Bernice S. Behar, CFA, leader of the fund's portfolio management team
since April 1996, is a senior vice president of the adviser. She joined the
adviser in 1991 and has been in the investment business since 1986.

INVESTOR EXPENSES

Financial Industries Fund

REGISTRANT NAME: JOHN HANCOCK INVESTMENT TRUST II
                                 TICKER SYMBOL   CLASS A: FIDAX   CLASS B: FIDBX
- --------------------------------------------------------------------------------
GOAL AND STRATEGY

[Clip art] The fund seeks capital appreciation. To pursue this goal, the fund
invests in U.S. and foreign financial services companies. These include banks,
thrifts, finance companies, brokerage and advisory firms, real estate-related
firms and insurance companies.

Under normal circumstances, the fund invests at least 65% of assets in these
companies.

PORTFOLIO SECURITIES

[Clip art] The fund invests primarily in the common stocks of U.S. and foreign
companies. It may also invest in warrants, preferred stocks and debt securities.

The fund may invest up to 5% of net assets in junk bonds.

For liquidity and flexibility, the fund may place up to 15% of net assets in
cash or in investment-grade short-term securities. In abnormal market
conditions, it may invest up to 80% in these securities as a defensive tactic.
The fund may also invest in certain higher-risk securities and may engage in
other investment practices.

RISK FACTORS

[Clip art] As with any growth fund, the value of your investment will fluctuate
in response to stock market movements. Because the fund concentrates in a single
sector, its performance is largely dependent on the sector's performance, which
may differ from that of the overall stock market. Falling interest rates or
deteriorating economic conditions can adversely affect the performance of
financial services companies' stocks, while rising interest rates will cause a
decline in the value of any debt securities the fund holds. Before you invest,
please read "More about risk" starting on page 30.

PORTFOLIO MANAGEMENT

[Clip art] James K. Schmidt, CFA, and Thomas Finucane lead the fund's portfolio
management team. Mr. Schmidt has been in the investment business since 1974. He
joined the adviser in 1985 and is an executive vice president. Mr. Finucane has
been in the investment business since joining the adviser in 1990. He is a
second vice president.

INVESTOR EXPENSES

[Clip art] Fund investors pay various expenses, either directly or indirectly.
The figures below are based on Class A expenses for the past year, adjusted to
reflect any changes. No Class B shares were issued or outstanding during the
past year. Future expenses may be greater or less.

Other expenses                                   0.90%       0.90%
Total fund operating expenses                    1.20%       1.90%

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

- --------------------------------------------------------------------------------
Share class                     Year 1      Year 3      Year 5    Year 10
- --------------------------------------------------------------------------------
Class A shares                   $62         $86        $113        $188
Class B shares
 Assuming redemption
 at end of period                $69         $90        $123        $204
 Assuming no redemption          $19         $60        $103        $204

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

(1) Except for investments of $1 million or more; see "How sales charges are
    calculated."
(2) Does not include wire redemption fee (currently $4.00).
(3) Reflects the adviser's agreement to limit expenses (except for 12b-1 and
    other class-specific expenses). Without this limitation, management fees
    would be 0.80% for each class, other expenses would be 5.97% for each
    class and total fund operating expenses would be 7.07% for Class A and
    7.77% for Class B.
(4) Because of the 12b-1 fee, long-term shareholders may indirectly pay more
    than the equivalent of the maximum permitted front-end sales charge.

Growth Fund

REGISTRANT NAME: JOHN HANCOCK INVESTMENT TRUST III  TICKER SYMBOL CLASS A: JHNGX
- --------------------------------------------------------------------------------
CLASS B: JHGBX
- --------------

Goal and strategy

[Clip art] The fund seeks long-term capital appreciation. To pursue this goal,
the fund invests in stocks that are diversified with regard to industries and
issuers. The fund favors stocks of companies whose operating earnings and
revenues have grown more than twice as fast as the gross domestic product over
the past five years, although not all stocks in the fund's portfolio will meet
this criterion.

Portfolio securities

[Clip art] The portfolio invests primarily in the common stocks of U.S.
companies. It may also invest in warrants, preferred stocks and convertible debt
securities.

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

Risk factors

[Clip art] As with any growth fund, the value of your investment will fluctuate
in response to stock market movements. To the extent that the fund invests in
higher-risk securities, it takes on additional risks that could adversely affect
its performance. Before you invest, please read "More about risk" starting on
page 30.

Portfolio management

[Clip art] Anurag Pandit, CFA, is leader of the fund's portfolio management
team. A second vice president of the adviser, Mr. Pandit has been a member of
the management team since joining John Hancock Funds in April 1996. He assumed
leadership of the team on January 1, 1997. Mr. Pandit has been in the investment
business since 1984.

(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.

Regional Bank Fund

REGISTRANT NAME: JOHN HANCOCK INVESTMENT TRUST II  
                                   TICKER SYMBOL  CLASS A: FRBAX CLASS B: FRBFX
- --------------------------------------------------------------------------------
GOAL AND STRATEGY

[Clip art] The fund seeks long-term capital appreciation. To pursue this goal,
the fund invests in regional banks and lending institutions, including:
o commercial and industrial banks
o savings and loan associations
o bank holding companies

These financial institutions provide full-service banking, have primarily
domestic assets and are typically based outside of New York City and Chicago.
They may or may not be members of the Federal Reserve, and their deposits may or
may not be FDIC-insured.

Under normal circumstances, the fund invests at least 65% of assets in these
companies; it may invest up to 35% of assets in other financial services
companies, including lending companies and money center banks. The fund may
invest up to 5% of net assets in stocks of non-financial services companies and
up to 5% in junk bonds issued by banks. Because regional banks typically pay
regular dividends, moderate income is an investment goal.

PORTFOLIO SECURITIES

[Clip art] The fund invests primarily in the common stocks of U.S. companies. It
may also invest in warrants, preferred stocks and investment-grade convertible
debt securities, as well as foreign stocks.

For liquidity and flexibility, the fund may place up to 15% of net assets in
cash or in investment-grade short-term securities. In abnormal market
conditions, it may invest up to 80% in these securities as a defensive tactic.
The fund may also invest in certain higher-risk securities, and may engage in
other investment practices.

RISK FACTORS

[Clip art] As with any growth fund, the value of your investment will fluctuate
in response to stock market movements. Because the fund concentrates in a single
industry, its performance is largely dependent on the industry's performance,
which may differ in direction and degree from that of the overall stock market.
Falling interest rates or deteriorating economic conditions can adversely affect
the performance of bank stocks, while rising interest rates will cause a decline
in the value of any debt securities the fund holds. Before you invest, please
read "More about risk" starting on page 30.

PORTFOLIO MANAGEMENT

[Clip art] James K. Schmidt, CFA, joined John Hancock in 1985 and has served as
the fund's portfolio manager since its inception that year. An executive vice
president of the adviser, he has been in the investment business since 1974.

The fund is temporarily closed to new investments except for existing accounts
(see the statement of additional information).

INVESTOR EXPENSES

[Clip art] Fund investors pay various expenses, either directly or indirectly.

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.

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

GOAL AND STRATEGY

[Clipart] The fund seeks long-term capital appreciation. To pursue this goal,
the fund invests in small-capitalization companies and companies in situations
offering unusual or non-recurring opportunities. Under normal circumstances, the
fund invests at least 65% of assets in a diversified portfolio of these
companies. The fund looks for companies that dominate an emerging industry or
hold a growing market share in a fragmented industry, and that have demonstrated
annual earnings and revenue growth of at least 25%, self-financing capabilities
and strong management. The fund does not invest for income.

PORTFOLIO SECURITIES

[Clipart] The fund invests primarily in the common stocks of U.S. and foreign
companies. It may also invest in warrants, preferred stocks and investment-grade
convertible debt securities.

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

RISK FACTORS

[Clipart] As with any growth fund, the value of your investment will fluctuate
in response to stock market movements. Stocks of small-capitalization and
special-situation companies carry higher risks than stocks of larger companies.
This is because these companies: 
o  may lack proven track records
o  may be dependent on a small number of products or services
o  may be undercapitalized 
o  may have highly priced stocks that are sensitive to adverse news

In addition, stocks of these companies are often traded in low volumes, which
can increase market and liquidity risks. Before you invest, please read "More
about risk" starting on page 30.

MANAGEMENT/SUBADVISER

[Clipart] Michael P. DiCarlo is responsible for the fund's day-to-day investment
management. He has served as the fund's portfolio manager since January 1988,
and has been in the investment business since 1984. He is currently one of three
principals in DFS Advisors, LLC, which was founded in 1996 and serves as
subadviser to the fund.

This fund will be closed to new investors at the end of the day its total assets
reach $2.5 billion. Further investments will be limited to existing accounts.

Special Opportunities Fund

REGISTRANT NAME: JOHN HANCOCK INVESTMENT TRUST III

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

GOAL AND STRATEGY

[Clipart] The fund seeks long-term capital appreciation. To pursue this goal,
the fund invests in those economic sectors that appear to have a higher than
average earning potential.

Under normal circumstances, at least 75% of the fund's equity securities is
invested within five or fewer sectors (e.g., financial services, energy,
technology). At times, the fund may focus on a single sector. The fund first
determines the inclusion and weighting of sectors, using macroeconomic as well
as other factors, then selects portfolio securities by seeking the most
attractive companies. The fund may add or drop sectors. Because the fund may
invest more than 5% of assets in a single issuer, it is classified as a
non-diversified fund.

PORTFOLIO SECURITIES

[Clipart] The fund invests primarily in common stocks of U.S. and foreign
companies of any size. It may also invest in warrants, preferred stocks,
convertible debt securities, U.S. Government securities and corporate bonds
rated at least BBB/Baa, or equivalent, and may invest in certain higher-risk
securities. The fund also may make short sales of securities and may engage in
other investment practices.

For liquidity and flexibility, the fund may place assets in cash or invest in
investment-grade short-term securities. 

RISK FACTORS 

[Clipart] As with any growth fund, the value of your investment will fluctuate
in response to stock market movements. By focusing on a relatively small number
of sectors or issuers, the fund runs the risk that any factor influencing those
sectors or issuers will have a major effect on performance. The fund may invest
in companies with smaller market capitalizations, which represent higher
near-term risks than larger capitalization companies. These factors make the
fund likely to experience higher volatility than most other types of growth
funds. Before you invest, please read "More about risk" starting on page 30.

    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 growth funds offer two classes of shares, Class A and Class B.
Each class has its own cost structure, allowing you to choose the one that best
meets your requirements. Your financial representative can help you decide.

- --------------------------------------------------------------------------------
Class A                                   Class B

o   Front-end sales charges, as           o   No front-end sales charge; all    
    described below. There are several        your money goes to work for you   
    ways to reduce these charges, also        right away.                       
    described below.                                                            
                                          o   Higher annual expenses than Class

                                          o   A deferred sales charge on shares 
                                              you sell within six years of      
                                              purchase, as described below.

                                              shares after eight years, thus    
                                              reducing future annual expenses.  

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

Special Equities Fund offers Class C shares, which have their own expense
structure and are available to financial institutions only. Call Signature
Services for more information (see the back cover of this prospectus).

- --------------------------------------------------------------------------------
HOW SALES CHARGES ARE CALCULATED

Class A Sales charges are as follows:

- -------------------------------------------------------------------------------
Class A sales charges
- -------------------------------------------------------------------------------
                           As a % of       As a % of your
Your investment            offering price  investment

Up to $49,999              5.00%           5.26%
$50,000 - $99,999          4.50%           4.71%
$100,000 - $249,999        3.50%           3.63%
$250,000 - $499,999        2.50%           2.56%
$500,000 - $999,999        2.00%           2.04%
$1,000,000 and over        See below

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

- --------------------------------------------------------------------------------
CDSC on $1 million+ investments
- --------------------------------------------------------------------------------
Your investment                CDSC on shares being sold

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

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

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

Class B Shares are offered at their net asset value per share, without any
initial sales charge. However, there is a contingent deferred sales charge
(CDSC) on shares you sell within six years of buying them. 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:

- --------------------------------------------------------------------------------
Class B deferred charges
- --------------------------------------------------------------------------------
Years after purchase            CDSC on shares being sold

1st year                        5.00%
2nd year                        4.00%
3rd or 4th year                 3.00%
5th year                        2.00%
6th year                        1.00%
After 6 years                   None

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

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

SALES CHARGE REDUCTIONS AND WAIVERS

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

o  Accumulation Privilege -- lets you add the value of any Class A shares you
   already own to the amount of your next Class A investment for purposes of
   calculating the sales charge.

o  Letter of Intention -- lets you purchase Class A shares of a fund over a
   13-month period and receive the same sales charge as if all shares had been
   purchased at once.

o  Combination Privilege -- lets you combine Class A shares of multiple funds
   for purposes of calculating the sales charge.

To utilize: complete the appropriate section of your application, or contact
your financial representative or Signature Services to add these options to an
existing account.

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

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

CDSC waivers As long as Signature Services is notified at the time you sell, the
CDSC for either share class will generally be waived in the following cases: 

o to make payments through certain systematic withdrawal plans
o to make certain distributions from a retirement plan 
o because of shareholder death or disability

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

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

To utilize: contact your financial representative or Signature Services.

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

o  government entities that are prohibited from paying mutual fund sales charges
o  financial institutions or common trust funds investing $1 million or more for
   non-discretionary accounts 
o  selling brokers and their employees and sales representatives
o  financial representatives utilizing fund shares in fee-based investment
   products under agreement with John Hancock Funds
o  fund trustees and other individuals who are affiliated with these or other
   John Hancock funds 
o  individuals transferring assets to a John Hancock fund from an employee 
   benefit plan that has John Hancock funds
o  members of an approved affinity group financial services program
o  certain insurance company contract holders (one-year CDSC usually applies) o
   participants in certain retirement plans with at least 100 members (one-year
   CDSC applies)

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

Selling shares in writing In certain circumstances, you will need to make your
request to sell shares in writing. You may need to include additional items with
your request, as shown in the table below. You may also need to include a
signature guarantee, which protects you against fraudulent orders. You will need
a signature guarantee if:

o your address of record has changed within the past 30 days

o you are selling more than $100,000 worth of shares

o you are requesting payment other than by a check mailed to the address of
  record and payable to the registered owner(s)

You can generally obtain a signature guarantee from the following sources:

o a federal savings, cooperative or other type of bank

o a savings and loan or other thrift institution

o a credit union 

o a securities exchange or clearing agency

A notary public CANNOT provide a signature guarantee.

TRANSACTION POLICIES

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

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

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

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

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

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

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

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

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

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

Eligibility by state You may only invest in, or exchange into, fund shares
legally available in your state.

- --------------------------------------------------------------------------------
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 distribute most or all of their net earnings in
the form of dividends. Any capital gains are distributed annually. Most of the
funds do not typically pay income dividends, with the exception of Disciplined
Growth Fund and Regional Bank Fund, which typically pay income dividends
semi-annually and quarterly, respectively.


                                                                 YOUR ACCOUNT 25
<PAGE>

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.


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. Corporations may be entitled to take a dividends-received
deduction for a portion of certain dividends they receive.

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.

Retirement plans John Hancock Funds offers a range of qualified retirement
plans, including IRAs, SIMPLE plans, SEPs, 401(k) plans, 403(b) plans (including
TSAs) and other pension and profit-sharing plans. Using these plans, you can
invest in any John Hancock fund (except tax-free income funds) with a low
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 growth 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 growth 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 Discovery Fund, Emerging Growth Fund, Financial
Industries Fund and Special Opportunities Fund, each fund's investment goal is
fundamental and may only be changed with shareholder approval.

Diversification Except for Special Opportunities Fund, all of the growth 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 authorizing annual fees of this type). The 12b-1 fee rates
vary by fund and by share class, according to Rule 12b-1 plans adopted by the
funds. The sales charges and 12b-1 fees paid by investors are detailed in the
fund-by-fund information. The portions of these expenses that are reallowed to
financial services firms are shown on the next page.

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

Special Opportunities      $   7,346,826     4.20%

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

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

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

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

MORE ABOUT RISK

A fund's risk profile is largely defined by the fund's primary 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 page are brief descriptions of these
securities and 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 the performance of a John
Hancock growth fund will be positive over any period of time -- days, months or
years. However, stock funds as a category have historically performed better
over the long term than bond or money market funds.

- --------------------------------------------------------------------------------
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.

Information risk The risk that key information about a security or market is
inaccurate or unavailable.

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. These fluctuations may cause a security to
be worth less than the price originally paid for it, or less than it was worth
at an earlier time. Market risk may affect a single issuer, industry, sector of
the economy 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.

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