Dear Fellow Shareholder:

I am  writing  to ask for  your  vote on an  important  matter  concerning  your
investment in the John Hancock's mutual funds for which Independence  Investment
LLC  (Independence)  serves  as  investment  sub-adviser.   The  attached  proxy
statement  contains  information  about a proposal to retain a successor entity,
with the same portfolio management staff as Independence, as sub-adviser to your
fund.  Another  proposal  would grant  greater  power to the  trustees to retain
sub-advisers in the future without shareholder approval.

Why are changes being proposed?

Independence  has served as the  sub-adviser  to John  Hancock Core Equity Fund,
John Hancock Independence Diversified Core Equity Fund II and John Hancock Small
Cap Fund, since 1992, 1995, and 1998  respectively.  Independence is currently a
subsidiary  of Manulife  Financial  Corporation  ("Manulife").  A subsidiary  of
Manulife  has entered into an agreement  with the parent of  Convergent  Capital
Management  ("Convergent")  pursuant to which substantially all of the assets of
Independence  will be  transferred  to a newly formed  subsidiary  of Convergent
("New  Independence").  The same portfolio management team will manage your fund
at New Independence as currently manages your fund at Independence. John Hancock
Advisers,  LLC believes that retaining New  Independence  as sub-adviser to your
fund is in the best interest of  shareholders  because it promotes the long-term
continuity of your fund's  strategy and  management.  The existing  sub-advisory
contract with  Independence  will  automatically  terminate due to the change in
control of Independence.

No Impact on Fund Expenses

There  will be no change to your  fund's  management  fee as a result of the new
sub-advisory  agreements.  Under the sub-investment  management  contract,  John
Hancock  Advisers,   LLC  will  pay  a  percentage  of  its  management  fee  to
Independence.   The  proxy  statement   includes  details  of  the  compensation
agreement.

Manager of Managers Policy

The board of trustees of your funds also propose that  shareholders of each fund
approve a policy that will allow John  Hancock  Advisers,  LLC and your board of
trustees to retain sub-advisers in the future without shareholder approval. This
authority will save the cost and time of a proxy  solicitation  in the future if
your  board of  trustees  determines  that it is  appropriate  to  appoint a new
sub-adviser to any of the funds.

Your Vote Matters

After careful  consideration,  your fund's trustees  recommend you vote for this
proposal.   The  enclosed  proxy  statement  contains  further  explanation  and
important details of the sub-investment  management  contract,  which I strongly
encourage  you to read  before  voting.  If approved  by the  shareholders,  the
contract will become effective on July 14, 2006.

Your vote makes a difference, no matter what the size of your investment. Please
review the enclosed  proxy  materials  and submit your vote  promptly to help us
avoid  the  need  for  additional  mailings  at your  Fund's  expense.  For your
convenience,  you  may  vote  one  of  three  ways:  via  telephone  by  calling
1-XXX-XXX-XXXX;  via mail by  returning  the enclosed  voting  card;  or via the
Internet by visiting www.jhfunds.com and selecting the shareholder entryway.

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

Sincerely,


Keith Hartstein
Chief Executive Officer
John Hancock Advisers, LLC

                                  INTRODUCTION

This  proxy  statement  is being  used at the  special  meeting  of each  fund's
shareholders  to be  held  concurrently  (collectively,  the  "Meeting")  at the

                                   PROPOSAL 1

                                APPROVAL OF A NEW
                       SUB-INVESTMENT MANAGEMENT CONTRACT


John Hancock  Advisers,  LLC (the  "adviser")  serves as each fund's  investment
adviser and is responsible for providing each fund with a continuous  investment
program under an investment  management contract (a "management  contract") with
each fund.  To manage the  day-to-day  investment  of each  fund's  assets,  the
adviser has retained Independence as sub-adviser.

Independence  is  currently  a  subsidiary  of  Manulife  Financial  Corporation
("Manulife").  A subsidiary  of Manulife has entered into an agreement  with the
parent  of  Convergent  Capital  Management  ("Convergent")  pursuant  to  which
substantially  all of the assets of Independence  will be transferred to a newly
formed subsidiary ("New  Independence") of Convergent (the  "Transaction").  The
adviser  believes that retaining New Independence as sub-adviser to your fund is
in  the  best  interest  of  shareholders  because  it  promotes  the  long-term
continuity  of your fund's  investment  strategy  and  management.  The existing
sub-advisory contract with Independence will automatically  terminate due to the
change in control of Independence.

The  sub-advisory  fees payable  under each proposed  sub-investment  management
contract will be borne by the adviser and not by a fund.  This proposal will not
have  any  effect  upon  the  fees  paid  by the  funds  to the  adviser  or the
consideration paid to the sub-adviser by the adviser. The adviser will be solely
responsible  for  paying  the  proposed  subadvisory  fee to  Independence.  The
investment  management  fees  payable  by each  Fund to the  adviser  under  the
management contracts will not change.

For a summary of the trustees' rationale for recommending that shareholders vote
to hire Independence, see "Analysis of Proposal and Review of Trustees" below.

About Independence Investment LLC

Independence Investment LLC ("Independence") located at 53 State Street, Boston,
MA 02109, is the subadviser to each fund.  Independence was founded in 1982, and
is an  indirect,  wholly-owned  subsidiary  of  Manulife.  At December 31, 2005,
Independence  managed  approximately  $7.7 billion in assets  under  management,
including the Funds, accounts of or controlled by Manulife or its affiliates and
third party accounts.

About Convergent

Convergent is an investment  management  holding company that currently operates
through nine  subsidiaries.  Collectively,  these Convergent  subsidiaries  have
assets  under  management  of  approximately  $8.5  billion.   Convergent  is  a
subsidiary of City National  Corporation,  a publicly traded financial  services
company located in California.

About the proposed change in control of Independence

The Transaction is structured as a sale of assets. New Independence will acquire
substantially   all  of  the  assets  of   Independence   and  assume   many  of
Independence's liabilities. New Independence will be a subsidiary of Convergent.
The  transaction  is not  anticipated  to have any  effect  upon  the  portfolio
management team or resources of the sub-adviser.  The portfolio  manager of each
fund has agreed to be an employee of New Independence.  Under the agreement with
Convergent,  all of the employees of Independence  are to be offered  employment
with  New  Independence.  Independence  believes  that  most  of its  employees,
including the portfolio  managers and analysts  responsible  for the each of the
funds and the executives  responsible for the management of  Independence,  will
become employees of New Independence.  The Transaction is not expected to result
in any  material  change in the manner in which New  Independence  conducts  its
business,  its  compliance  systems or resources or its  investment  operations.
There are no plans for changes in the portfolio management team for the funds or
in the current  executive  management of Independence.  No changes in investment
process or resources are anticipated to occur as a result of the Transaction.

In  consideration  for such transfer of assets and  assumption  of  liabilities,
Convergent will pay Manulife a specified  amount at closing.  Manulife will also

                                       2


receive additional  consideration on certain anniversary dates of the closing to
the extent the  revenue  received by New  Independence  from the  management  of
proprietary  accounts  of Manulife  and its  affiliates  or  accounts  for which
Manulife or its affiliates act as investment adviser,  including the funds, meet
certain revenue  targets.  Consequently,  while the contingent  payments are not
dependent upon the approval or  continuation  of the  sub-investment  management
contracts with respect to any fund, the revenues earned by New Independence as a
result of its  sub-advisory  relationship  with respect to the funds would count
towards the revenue target necessary to earn the contingent payments.

The closing of the  Transaction is subject to a number of customary  conditions,
including the  requirement  that the revenue run rate of New  Independence  from
consenting  clients is not less than 77.5% of the historical revenue run rate of
Independence.  However, the approval of new sub-investment  management contracts
for the funds,  while affecting the ability to achieve such revenue run rate, is
not a condition to the closing of the Transaction.  Convergent and Manulife have
agreed that in order to comply with Section 15(f) under the  Investment  Company
Act,  no unfair  burden  will be imposed on any of the funds for a period of two
years after the closing.  The adviser  expects the  Transaction  to close in the
second quarter of 2006, although there is no assurance that the Transaction will
be  completed  or as to the  actual  timing.  Nothing in the  agreement  between
Manulife and Convergent  imposes any limitations  upon the rights of the adviser
to recommend termination of the sub-investment management contract.

About the Adviser

The adviser is the  investment  adviser to each fund.  John Hancock is a unit of
Manulife  Financial  Corporation,  a leading  Canadian-based  financial services
group serving  millions of customers in 19 countries and territories  worldwide.

through John Hancock in the United States,  the Company offers clients a diverse

under  management  by  Manulife  Financial  and its  subsidiaries  were Cdn$ 372
billion (US$ 319 billion) as of December 31, 2005.

The adviser is located at 601 Congress Street,  Boston,  Massachusetts,  and was
organized in 1968.  The adviser had  approximately  $ 28 billion in assets under
management as of December 31, 2005 in its capacity as investment  adviser to the
funds in the John Hancock group of funds, as well as privately managed accounts.

The board of trustees of each fund is responsible for overseeing the performance
of each fund's investment  adviser and determining  whether to approve and renew
each fund's investment management contract.

below, along with their principal occupations.

Terms of the Proposed and Existing Sub-Investment Management Contracts

The  terms of each  fund's  proposed  sub-investment  management  contracts  are
substantially  the  same as the  terms  of the  fund's  existing  sub-investment
management  contracts,  except  for the dates of  execution,  effectiveness  and
termination. The sub-advisory fees to be paid by the adviser to New Independence
under the proposed sub-investment management contracts are identical to the fees
under the existing sub-investment  management contracts. All the terms described
below with respect to each fund's proposed  sub-investment  management  contract
are contained in the fund's existing  sub-investment  management  contract.  The
following  summary  of the  terms  of  the  proposed  sub-investment  management
contracts  is qualified  by  reference  to the  representative  form of proposed
sub-investment  management  contract attached to this proxy statement as Exhibit
A. Because the proposed  sub-investment  management  contracts are substantially
similar except for the sub-advisory fee rates, only one  representative  form of
proposed  sub-investment  management  contract  for these  funds is  included as
Exhibit A.

Compensation.  The proposed sub-investment management contracts provide that New
Independence  is required to pay all expenses that it incurs in connection  with
the performance of its duties under the sub-investment  management contract. The
sub-investment management contract also provides that the adviser, not the fund,
will pay the sub-advisory fees.

The following table shows the investment management fee and the sub-advisory fee
for each of the funds,  in each case  expressed as a percentage of average daily
net assets and the fees in dollars for the most recent fiscal year.

                                       4


Term.  If  approved  by  shareholders  of the  Fund,  the  proposed  subadvisory
contracts  will each take  effect as of July 14,  2006 and will remain in effect
until June 30, 2007. Thereafter, the proposed subadvisory contract will continue
in effect from year to year subject to the annual approval of its continuance as
described below under "Provisions  Contained in the subadvisory  Contract and in
the Management Contract".

Limitation of Liability of Sub-Adviser.  New Independence will not be liable for
any losses,  claims,  damages,  liabilities or litigation  (including  legal and
other expenses)  incurred or suffered by the adviser,  the funds or any of their
affiliates  as a  result  of any  error of  judgment  or  mistake  of law by New
Independence  with respect to the funds,  except that nothing in the subadvisory
agreement will limit New Independence's liability for New Independence's willful
misfeasance,  bad faith or gross negligence  generally in the performance of its
duties  hereunder or its reckless  disregard of its obligations and duties under
each sub-investment management contract.

Termination,  Continuance and Amendment. Each sub-investment management contract
will  continue  in effect  from year to year  subject to annual  approval of its
continuance  by a  majority  of the  independent  trustees,  cast in person at a
meeting called for the purpose of voting on such approval,  and annual  approval
by either (a) each fund's trustees, or (b) a majority of each fund's outstanding
voting securities,  as defined in the Investment Company Act of 1940, as amended
(the "1940 Act"). Each  sub-investment  management contract may be terminated at
any time without  penalty on 60 days' written notice by the trustees,  by a vote
of a majority of a fund's outstanding  voting  securities,  or by the adviser or
subadvisor.  The sub-investment  management contract terminates automatically in
the event of its  assignment  or in the event that the adviser  ceases to act as
the fund's investment adviser.

The Management Contract

Under each fund's management contract, the adviser,  subject to the direction of
the trustees,  provides each fund with a continuous  investment  program for the
management of its assets,  consistent with such Fund's investment  objective and
policies.  The  adviser  furnishes  each fund with  advice  and  recommendations
consistent  with the  investment  policies of the fund  regarding  the purchase,
holding and disposition of portfolio securities. The adviser:

  o  advises  the fund in  connection  with policy  decisions  to be made by the
     trustees;
  o  furnishes  the  fund  with  research,  economic  and  statistical  data  in
     connection with the Fund's investments and policies;
  o  provides day-to-day administration;
  o  investigates  and  conducts  relations  with  issuers of  securities  to be
     purchased by the fund;
  o  provides required reports and recommendations to the trustees and maintains
     the records of the fund; and
  o  assists the fund in any  negotiations  relating  to the fund's  investments
     with issuers,  investment banking firms,  securities brokers or dealers and
     other institutions or investors.

The adviser provides each fund with office space,  supplies and other facilities
required for the business of the funds. The adviser pays the compensation of all
officers and  employees  of the fund and pays the expenses of clerical  services
related to the  administration  of the funds.  Other than expenses  specifically
assumed by the adviser, all expenses incurred in the continuing operation of the
funds are borne by each fund, including fees of the independent trustees and all
fees of lawyers and accountants.

Limitation of Liability.  Each management  contract provides that the adviser is
not liable for any error of judgment or mistake of law or for any loss  suffered
by the Fund in  connection  with the  matters to which the  management  contract
relates,  except a loss resulting from willful  misfeasance,  bad faith or gross
negligence on the part of the adviser in the  performance  of its duties or from
the reckless disregard of its obligations and duties under the contract.

Interim Sub-Investment Management Contract

Under the  Investment  Company Act of 1940 (the "1940 Act"),  shareholders  must
approve any new investment  management and sub-investment  management  contracts
for the funds.  However,  Rule 15a-4 under the 1940 Act permits your trustees to
appoint New  Independence  as  sub-adviser  on an interim  basis  without  prior


                                       5


shareholder  approval if New Independence agrees to provide such services on the
same terms as  Independence  and approval of the new  sub-investment  management
contracts  are  submitted  to  shareholders  within  150  days of the  date  New
Independence  begins to manage the funds. Your trustees approved the appointment
of New Independence as interim sub-adviser on May 2, 2006.

Because  Manulife  will  be  receiving  consideration  in  connection  with  the
Transaction,  any fees  that New  Independence  would be  entitled  to under the
interim  sub-investment  management contract will be held in escrow by the funds
until shareholders  approval is obtained. If New Independence is not approved as
sub-adviser  to a fund,  New  Independence  will not  receive  the fee under the
current sub-investment management contract but instead would be paid a fee based
upon New  Independence's  cost in  managing  the fund or the fee in the  interim
sub-investment  management contract if lower. If New Independence's  appointment
as sub-adviser  is not approve by  shareholders  by [ ], 2006, New  Independence
will  no  longer  provide  sub-advisory  services  to  the  funds.  Approval  by
shareholders  of the new  sub-investment  management  contract with respect to a
fund will also  constitute  approval  of the interim  sub-investment  management
contract.

The interim  agreement  incorporates  the terms of the  existing  sub-investment
management contraccts, which are discussed above.

Board  Consideration  of approval  of New  Sub-Investment  Management  Contracts

Section 15(c) of the 1940 Act requires that your trustees,  including a majority
of the  trustees who have no direct or indirect  interest in the  sub-investment
management  contracts and are not "interested  persons" of the funds, as defined
in the 1940 Act (the  "Independent  Trustees"),  approve  the  adoption  of each
sub-investment  management  contract with New Independence.  At meetings held on
May 2, 2006, your trustees,  including the Independent Trustees,  considered the
factors and reached the conclusions described below relating to the selection of
New   Independence  as  sub-adviser  to  the  funds  and  the  approval  of  the
sub-investment    management    contracts.    During    such    meetings,    the
Contracts/Operations   Committee  and  the  Independent  Trustees  also  met  in
executive  sessions with their  independent  legal  counsel.  In evaluating  the
sub-investment     management    contracts,    the    Board,    including    the
Contracts/Operations  Committee and the Independent  Trustees,  reviewed a broad
range of  information  requested for this purpose by the  Independent  Trustees,
including but not limited to the following:  (i) the  investment  performance of
each fund and a broader universe of relevant funds (the "Universe")  selected by
Morningstar,  an independent provider of investment company data, for a range of
periods, (ii) advisory, sub-advisory and other fees incurred by, and the expense
ratios  of,  each  fund  and a  peer  group  of  comparable  funds  selected  by
Morningstar (the "Peer Group"), (iii) the fees of comparable portfolios of other
clients of New  Independence,  (iv)  Independence's  record of  compliance  with
applicable  laws and  regulations,  with each  fund's  investment  policies  and
restrictions,  and  with  the  funds'  Code  of  Ethics  and the  structure  and
responsibilities of the Adviser's and Sub-Adviser's  compliance department,  (v)
the background and experience of senior management and investment  professionals
of New  Independence,  (vii)  the  potential  impact of the  Transaction  on the
management  and  resources of New  Independence  and (vii) the nature,  cost and
character of sub-investment management services provided by Independence.

Nature, Extent and Quality of Services. The Boards considered the ability of New
Independence,  based on its  resources,  reputation  and  other  attributes,  to
attract  and retain  qualified  investment  professionals,  including  research,
advisory,  and  supervisory   personnel.   The  Boards  further  considered  the
compliance  programs and compliance records of Independence.  Based on the above
factors, together with those referenced below, the Boards concluded that, within
the context of its full  deliberations,  the  nature,  extent and quality of the
investment  advisory  services  provided  to  each  fund  by  Independence  were
sufficient to support appointment of New Independence as sub-adviser.

Fund Performance.  The Boards  considered the performance  results for each fund
over  various  time  periods.  The  Boards  also  considered  these  results  in
comparison to the performance of the Universe,  as well as the fund's  benchmark
indices.  Morningstar  determined  the Universe for each fund.  The Boards noted
that with  respect to Core Equity  Fund,  although  the fund has  underperformed
against its peer group over five and ten year  period,  the Fund is in the first
and  second  quartiles  relative  to its peer  group over the one and three year
periods  respectively,  With respect to Diversified Core Equity,  the Fund is in
the first or second quartile of its peer group for the one, three,  five and ten
year period. With respect to the Small Cap Fund, the Fund's performance over the
five year period was in the first  quartile of the peer group,  with the shorter
term performance being below the peer group.


                                       6


Sub-Advisory  Fee Rates.  The Boards  reviewed and  considered  the  contractual
investment  management  fee  rates  payable  by  each  fund to the  adviser  for
investment  advisory services (the "Advisory Agreement Rate. The Boards received
and considered  information  comparing the Advisory Agreement Rate with those of
the other  funds in the Peer  Group.  The Boards also  received  and  considered
information  regarding each fund's total operating expense ratio and its various
components,   including   contractual   advisory  fees,  actual  advisory  fees,
non-management  fees, Rule 12b-1 and non-Rule 12b-1 service fees, transfer agent
fees and custodian  fees,  including and excluding Rule 12b-1 and non-Rule 12b-1
service fees.  The Boards also  considered  comparisons of these expenses to the
expense  information  for the Peer  Group  and the  Universe.  The  Boards  also
received   information   about  the  investment   sub-advisory   fee  rate  (the
"Sub-Advisory  Agreement  Rate")  payable by the  adviser to  Independence.  The
Boards  concluded that the  Sub-Advisory  Agreement Rate was fair and equitable,
based on its consideration of the factors described above.

Information   About  Services  to  Other  Clients.   The  Boards  also  received
information  about the  nature,  extent and  quality of  services  and fee rates
offered  by  Independence  to its  other  clients,  including  other  registered
investment companies,  institutional investors and separate accounts. The Boards
concluded that the Sub-Advisory Agreement Rate was not unreasonable, taking into
account fee rates  offered to others by New  Independence  and giving  effect to
differences in services covered by such fee rates.

Other  Factors and Broader  Review.  As  discussed  above,  the Boards  reviewed
detailed  materials  received  from  New  Independence  in  connection  with the
approval  process under Section 15(c) of the 1940 Act. The Board also  regularly
reviews  and  assesses  the  quality  of the  services  that the funds  receives
throughout the year.

After considering the above-described factors and based on its deliberations and
its evaluation of the information  described  above,  the Boards  concluded that
approval  of  the  continuation  of  the  sub-investment   management  contracts
(including the interim sub-investment management contracts) for each fund was in
the best  interest  of each fund and its  shareholders.  Accordingly,  the Board
unanimously approved the approval of the sub-investment management contracts.

Required vote

Approval  of  this  proposal  requires  the  affirmative  of a  majority  of the
outstanding  shares or 66 2/3% of the shares  present at meeting if at least 50%
of the  outstanding  shares are present and  entitled to vote at such meeting (a
"1940  Act  Majority  Vote").  If a fund does not  approve  this  proposal,  the
sub-investment  management  contract will  terminate and the adviser will manage
the fund.

Trustees' Recommendation

The trustees,  including all of the  independent  trustees,  by a vote cast at a
meeting held on May 2, 2006  unanimously  approved and voted to recommend to the
shareholders  of each  Fund  that  each  Fund  adopt  the  proposed  subadvisory
contract.  If the Funds' shareholders approve the proposed subadvisory contract,
that contract will take effect as of July 14, 2006.

If the proposed  subadvisory  contract is not  approved for a Fund,  such Fund's
trustees  will  consider  what  action,  if  any,  should  be  taken  to  obtain
subadvisory services for the Fund.

The  trustees of your Fund  recommend  that the  shareholders  of your Fund vote
"for" the proposed subadvisory contract.

                                   PROPOSAL 2

      APPROVAL OF A POLICY ALLOWING JOHN HANCOCK ADVISERS AND THE BOARD OF
   TRUSTEES TO APPOINT OR TERMINATE SUB-ADVISERS AND TO APPROVE AMENDMENTS TO
              SUB-ADVISORY AGREEMENTS WITHOUT SHAREHOLDER APPROVAL

Summary

At the board of trustees'  meeting held on May 2, 2006, the trustees,  including
the Independent  Trustees,  approved,  and recommended that  shareholders of the
fund approve, a policy to permit the adviser to appoint  sub-advisers,  to enter
into  sub-advisory  agreements and to amend or terminate  existing  sub-advisory
agreements  (including the  sub-investment  management  contracts in proposal 1)
without further shareholder  approval (the "sub-adviser  approval policy").  Any
such appointment or termination  would be subject to prior approval of the board
of trustees, including a majority of the Independent Trustees.

The Section 15 exemptive order

The John  Hancock  Funds  may rely  upon an  exemptive  order  from the SEC (the
"exemptive  order")  relieving them from certain  provisions of Section 15(a) of
the 1940 Act in connection with the sub-adviser  approval policy.  The exemptive
order applies to John Hancock Funds that meet the  conditions of the order.  The
provisions of the 1940 Act require that  shareholders of a mutual fund approve a
sub-advisory  agreement  with the  sub-adviser  and  material  amendments  to an
existing  sub-advisory  agreement.  If shareholders  approve this proposal,  the
adviser will be  authorized,  subject to approval by the board of  trustees,  to
evaluate, select and retain one or more sub-advisers for each fund, terminate or
replace any  sub-adviser so approved or modify any  sub-advisory  agreement with
respect  to  any  fund  without   obtaining   further  approval  of  the  fund's
shareholders. The trustees and John Hancock Advisers would be authorized to take
such actions  whenever they  determine that such actions will benefit a fund and
its shareholders.

Shareholder approval policy

The  adviser  has  served  as the  investment  adviser  to each  fund  since its
inception,  except for John  Hancock  Small Cap Fund for which the  adviser  has
served as investment  adviser since 2004. The adviser represents that it has the
experience and expertise to evaluate,  select and supervise sub-advisers who can
add value to shareholders' investments in the funds.

Approval  of  the  sub-adviser  approval  policy  will  not  affect  any  of the
requirements under the federal securities laws that govern any of the funds, the
adviser, any proposed sub-adviser, or any proposed sub-advisory agreement, other
than the requirement to have a sub-advisory  agreement  approved at a meeting of
the fund's  shareholders.  The board of  trustees  of each fund,  including  the
Independent Trustees, will continue to evaluate and approve all new sub-advisory
agreements between the adviser and any sub-adviser as well as all changes to any
sub-advisory  agreements.  In addition, the fund and the adviser will be subject
to several  conditions  imposed by the SEC to ensure that the  interests  of the
fund's shareholders are adequately protected whenever John Hancock Advisers acts
under  the  sub-adviser  approval  policy.  Furthermore,  within  90 days of the
adoption of or a change to the fund's sub-advisory  arrangements,  the fund will
provide you with an information  statement that contains  substantially the same
relevant information about the sub-adviser,  the sub-advisory  agreement and the
sub-advisory  fee  that the fund  would  be  required  to send to you in a proxy
statement.  This  information  statement will permit the fund's  shareholders to
determine  if they are  satisfied  with  the  sub-advisory  arrangement.  If not
satisfied,  the shareholders  would be able to exchange their shares for another
fund or redeem  their  shares.  Exchanges  and  redemptions  may be  subject  to
transaction or distribution fees and generally are taxable transactions.

Shareholder approval of this proposal will not result in an increase or decrease
in the total amount of investment advisory fees paid by the fund to the adviser.
If the fund  implements  this policy,  the adviser,  pursuant to its  investment
management   contract  with  the  fund,  will  continue,   directly  or  through
sub-advisers,  to  provide  the same  level  of  management  and  administrative
services  to  the  fund  as it  has  always  provided.  The  funds  will  not be
responsible for the payment of any sub-advisory fees.

The  exemptive  relief  applies to at least the  following  situations:  (1) the


                                       8


adviser  determines to retain a  sub-adviser  for all or a portion of any fund's
assets;  (2) a  sub-adviser  is  removed  for  substandard  performance;  (3) an
individual  acting as a fund's portfolio  manager moves from employment with one
sub-adviser  to another firm,  which the adviser then appoints as a sub-adviser;
(4) there is a change of control of a  sub-adviser;  (5) the adviser  decides to
diversify a fund's management by adding an additional sub-advisers; (6) there is
a  change  in  investment  style of a fund;  and (7) the  adviser  negotiates  a
reduction (or the sub-adviser  negotiates an increase) in the  sub-advisory  fee
that the adviser pays to a sub-adviser.  If the adviser negotiates a decrease in
the  compensation  that it pays any sub-adviser and effectively  retains more of
the  advisory fee for itself,  no  shareholder  action  would be  required.  The
sub-adviser  approval  policy will not be used to approve any subadviser that is
affiliated  with  Manulife as that term is used in the 1940 Act or to materially
amend any sub-advisory agreement with an affiliated sub-adviser.

Reasons for requesting Section 15 exemptive relief

The  trustees  believe  that it is in the  best  interest  of each  fund and its
shareholders  to allow the adviser  the  flexibility  to provide its  investment
advisory  services  to the fund  through  one or more  sub-advisers  which  have
particular  expertise in the type of investments  on which the fund focuses.  In
addition,   the  trustees  believe  that  providing  the  adviser  with  maximum
flexibility to select,  supervise and evaluate  sub-advisers - without incurring
the necessary delay or expense of obtaining further  shareholder  approval -- is
in the best interest of each fund's shareholders  because it will allow the fund
to operate more  efficiently.  Currently,  in order for the adviser to appoint a
sub-adviser or materially  modify a sub-advisory  agreement,  the fund must call
and  hold a  shareholder  meeting  of the  fund,  create  and  distribute  proxy
materials,  and solicit votes from the fund's  shareholders.  If for example, is
the reason for  proposal  1. This  process is  time-intensive,  costly and slow.
Without the delay inherent in holding shareholder meetings, the adviser would be
able to act more  quickly to appoint a  sub-adviser  when the  trustees  and the
adviser feel that the appointment would benefit a fund.

Also,  the  trustees  believe  that it is  appropriate  to vest  the  selection,
supervision and evaluation of the sub-advisers in the adviser (subject to review
by the board of trustees)  in light of the  adviser's  expertise  in  investment
management and its ability to select the most  appropriate  sub-adviser(s).  The
trustees  believe that many  investors  choose to invest in the funds because of
the  adviser's  investment  management  experience  and  expertise.  The adviser
believes that, if it becomes  appropriate to appoint a sub-adviser to a fund, it
can use this  experience and expertise in evaluating  and choosing  sub-advisers
who can add the most value to your investment in that fund. The adviser also has
experience in retaining and supervising sub-advisers.

Finally,  the trustees  will  provide  sufficient  oversight of the  sub-adviser
approval policy to ensure that  shareholders'  interests are protected  whenever
the adviser  selects a sub-adviser  or modifies a  sub-advisory  agreement.  The
board,  including  a majority  of the  Independent  Trustees,  will  continue to
evaluate and approve all new sub-advisory agreements as well as any modification
to existing sub-advisory agreements.  In their review, the trustees will analyze
all factors that they  consider to be relevant to the  determination,  including
the  nature,  quality and scope of services  provided by the  sub-advisers.  The
trustees will compare the  investment  performance  of the assets managed by the
sub-adviser with other accounts with similar  investment  objectives  managed by
other  advisers  and will  review  the  sub-adviser's  compliance  with  federal
securities laws and regulations.  Each sub-advisory agreement will be subject to
all provisions of the 1940 Act,  except for the specific  provisions of the 1940
Act from which the exemptive order provides relief.

Required vote

Approval of this proposal  requires the  affirmative  1940 Act Majority Vote (as
defined in Proposal 1 above) of the fund's  outstanding  shares.  If a fund does
not approve this proposal,  the sub-adviser  approval policy will not be adopted
with respect to that fund and decisions  regarding a proposed  sub-adviser  or a
material change to a sub-advisory agreement will continue to require shareholder
approval.

Recommendation

For the reasons set forth above, the trustees of your fund unanimously recommend
that  shareholders  vote in favor of the proposed  policy  allowing John Hancock
Advisers and the board of trustees to appoint or terminate  sub-advisers  and to
approve amendments to sub-advisory agreements without shareholder approval.

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

Outstanding Shares and Quorum

As of May 16, 2006 (the  "record  date"),  _______________shares  of  beneficial
interest of Small Cap Fund were outstanding; _______________shares of beneficial

                                       10


Only  shareholders of record on 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.

Other Business

The  funds'  boards  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, by the time  scheduled  for the  meeting,  a quorum of  shareholders  is not
present or if a quorum is present but  sufficient  votes "for" the proposal have
not  been  received,  the  persons  named as  proxies  may  propose  one or more
adjournments  of the  meeting to another  date and time,  and the meeting may be
held as adjourned  within a reasonable  time after the date set for the original
meeting  without  further  notice.   Any  such   adjournment  will  require  the
affirmative vote of a majority of the votes cast on the question in person or by
proxy at the  session  of the  meeting to be  adjourned.  The  persons  named as
proxies will vote all proxies in favor of the adjournment that voted in favor of
the proposal or that abstained.  They will vote against such  adjournment  those
proxies  required to be voted against the  proposal.  Broker  non-votes  will be
disregarded in the vote for adjournment.  If the adjournment  requires setting a
new record date or the  adjournment  is for more than 60 days from the  original
meeting  (in which case the board of trustees of your fund will set a new record
date), your fund will give notice of the adjourned meeting to its shareholders.

Telephone Voting

In addition to soliciting proxies by mail, by fax or in person, your Fund(s) may
also arrange to have votes  recorded by  telephone by officers and  employees of
your Fund(s) or by  personnel of the adviser or transfer  agent or a third party
solicitation  firm.  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.

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

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

o To ensure that the shareholder's  instructions  have been recorded  correctly,
the shareholder  will also receive a confirmation of the voting  instructions by
mail with a toll-free  number to call 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.

Internet Voting

You will also have the  opportunity to submit your voting  instructions  via the
Internet  by  utilizing  a program  provided  through a vendor.  Voting  via the
Internet  will not  affect  your right to vote in person if you decide to attend
the meting.  Do not mail the proxy card if you are voting via the  Internet.  To
vote via the Internet,  you will need the "control  number" that appears on your
proxy card.  These  Internet  voting  procedures  are  designed to  authenticate
shareholder  identities,  to allow shareholders give their voting  instructions,
and to confirm that shareholders  instructions have been recorded  properly.  If
you are voting via the  Internet you should  understand  that there may be costs
associated  with electronic  access,  such as usage charges from Internet access
providers and telephone companies, that must be borne to you.

o Read the proxy statement and have your proxy card at hand.



                                       11


o Go to the Web site on the proxy card.

o Enter the control number found on your proxy card.

o Follow the instructions on the Web site.  Please call us at  1-800-225-5291 if
  you have any problems.

o To  insure  that your  instructions  have been  recorded  correctly,  you will
  receive a  confirmation  of your voting  instructions  immediately  after your
  submission and also by e-mail if chosen.

Shareholder's Proposals

Your fund is not required and does not intend,  to hold meetings of shareholders
each  year.  Instead,  meetings  will be held  only  when and if  required.  Any
shareholders  desiring  to  present a  proposal  for  consideration  at the next
meeting  for  shareholders  must submit the  proposal in writing,  so that it is
received by your fund at 601 Congress Street, Boston, Massachusetts 02210 within

                     JOHN HANCOCK INSTITUTIONAL SERIES TRUST

                       SUB-INVESTMENT MANAGEMENT CONTRACT


     AGREEMENT made this ___ day of _______,  2006, among John Hancock Advisers,
LLC,  a  Delaware  limited  liability  company  (the  "Adviser"),   Independence
Investment,  LLC a Delaware limited  liability company (the  "Sub-adviser")  and
John Hancock  Institutional Series Trust, a business trust under the laws of the
Commonwealth  of  Massachusetts  (the  "Trust")  on behalf  of the John  Hancock
Independence  Diversified  Core  Equity  Fund II (the  "Fund"),  a series of the
Trust. In consideration of the mutual covenants  contained  herein,  the parties
agree as follows:

1.   APPOINTMENT OF SUB-ADVISER

     The  Sub-adviser  undertakes to act as investment  sub-adviser  to the Fund
and, subject to the supervision and control of the Trustees of the Trust and the
terms of this Agreement, to manage the investment and reinvestment of the assets
of the Fund. The Sub-adviser will be an independent  contractor and will have no
authority to act for or represent the Trust,  the Fund or the Adviser in any way
except as expressly authorized in this Agreement or another writing by the Trust
or the Adviser.

2.   SERVICES TO BE RENDERED BY THE SUB-ADVISER TO THE TRUST AND THE FUND

a.   Subject  always to the  direction and control of the Trustees of the Trust,
     the  Sub-adviser  shall have  investment  discretion over the assets of the
     Fund and will manage the investments and determine the composition of these
     assets in accordance with the Trust's registration  statement,  as amended.
     In fulfilling its obligations to manage the  investments and  reinvestments
     of the assets of the Fund, the Sub-adviser will:

     i.   obtain and evaluate  pertinent  economic,  statistical,  financial and
          other  information  affecting  the economy  generally  and  individual
          companies or  industries  the  securities of which are included in the
          Fund's  portfolio  or are under  consideration  for  inclusion  in the
          Fund's portfolio;

     ii.  formulate and implement a continuous  investment  program for the Fund
          that  is  consistent  with  the  investment   objectives  and  related
          investment   policies  for  the  Fund  as  described  in  the  Trust's
          registration statement, as amended, copies of which shall be furnished
          to the Sub-adviser promptly upon amendment;

     iii. take whatever steps are necessary to implement the investment  program
          by the  purchase  and sale of  securities,  including  the  placing of
          orders for such purchases and sales;

     iv.  regularly  report to the Trustees of the Trust and to the Adviser with
          respect to the implementation of the investment program; and


                                       A-1


     v.   provide  assistance to the Trust's custodian  regarding the fair value
          of  securities  held by the Fund for which market  quotations  are not
          readily available.

b.   The Sub-adviser,  at its expense, will furnish all necessary investment and
     management  facilities,  including salaries of personnel required for it to
     execute its duties faithfully.

c.   The Sub-adviser  will select brokers and dealers to effect all transactions
     subject  to the  following  conditions:  The  Sub-adviser  will  place  all
     necessary  orders with  brokers,  dealers,  or issuers  and will  negotiate
     brokerage  commissions,  if applicable.  The Sub-adviser is directed at all
     times to seek to execute brokerage  transactions for the Fund in accordance
     with such policies or practices as may be  established  by the Trustees and
     described in the Trust's registration statement, as amended, and consistent
     with its fiduciary  obligation to seek best execution.  Subject to policies
     established  from time to time by the Board of Trustees  of the Trust,  the
     Sub-adviser may pay a broker-dealer  which provides  research and brokerage
     services a higher spread or commission  for a particular  transaction  than
     otherwise  might  have  been  charged  by  another   broker-dealer  if  the
     Sub-adviser  determines  that the higher spread or commission is reasonable
     in relation to the value of the brokerage  and research  services that such
     broker-dealer   provides,   viewed  in  terms  of  either  the   particular
     transaction or the Sub-adviser's  overall  responsibilities with respect to
     accounts  managed  by the  Sub-adviser.  The  Sub-adviser  may  use for the
     benefit of the Sub-adviser's  other clients, or make available to companies
     affiliated  with the  Sub-adviser  or to its  directors  for the benefit of
     their  clients,   any  such  brokerage  and  research   services  that  the
     Sub-adviser obtains from brokers or dealers.

d.   On occasions when the Sub-adviser  deems the purchase or sale of a security
     to be in the best  interest  of the Fund as well as  other  clients  of the
     Sub-adviser,  the  Sub-adviser,  to the extent permitted by applicable laws
     and  regulations,  may, but shall be under no obligation to,  aggregate the
     securities  to be purchased  or sold to attempt to obtain a more  favorable
     price or lower  brokerage  commissions  and  efficient  execution.  In such
     event,  allocation  of the  securities so purchased or sold, as well as the
     expenses  incurred in the  transaction,  will be made by the Sub-adviser in
     the manner the  Sub-adviser  considers to be the equitable  and  consistent
     with its fiduciary obligations to the Fund and to its other clients.

e.   The Sub-adviser will maintain all accounts,  books and records with respect
     to the Fund as are required of an  investment  sub-adviser  of a registered
     investment  company  pursuant to the  Investment  Company  Act of 1940,  as
     amended (the "Investment Company Act") and Investment Advisers Act of 1940,
     as amended (the "Investment Advisers Act") and the rules thereunder.

f.   The  Sub-adviser  shall vote  proxies  relating  to the  Fund's  investment
     securities  in  accordance  with the  Trust's  proxy  voting  policies  and
     procedures,  which  provide  that the  Sub-adviser  shall vote all  proxies
     relating  to  securities  held by the  Fund  and,  subject  to the  Trust's
     policies and  procedures,  shall use proxy voting  policies and  procedures
     adopted by the  Sub-adviser  in  conformance  with Rule 206(4)-6  under the
     Investment  Advisers  Act.  The  Sub-adviser  shall review its proxy voting
     activities on a periodic basis with the Trustees and with the Adviser.

shall be liable to the Adviser or the Trust or Fund for any error of judgment or
mistake  of law or for  any  loss  suffered  by the  Adviser,  Trust  or Fund in
connection with the matters to which this Agreement  relates,  except for losses

the Agreement or its  continuance or of a new contract with the Sub-adviser or a
different adviser or sub-adviser or other definitive action;  provided, that the
compensation  received  by the  Sub-adviser  in respect of the Fund  during such

written  notice  to the  Adviser  and  the  Sub-adviser,  or by the  Adviser  or
Sub-adviser on sixty days' written notice to the Trust and the other party. This
Agreement will automatically  terminate,  without the payment of any penalty, in

has  advised  the  Trust's  Board  of  Trustees,  that the  Sub-adviser  and its
affiliates  may give  advice  and take  action  for  other  accounts,  including
investment companies, which differs from advice given or the timing or nature of
action  taken  for the  Fund.  The  Sub-adviser  is not  obligated  to  initiate

     The Sub-adviser  shall serve as investment  sub-adviser for the Fund listed
below.  The  Adviser  will pay the  Sub-adviser,  as full  compensation  for all
services  provided  under  this  Agreement  with  respect  to the Fund,  the fee
computed separately for such Fund at an annual rate as follows (the "Sub-adviser
Fee"):



                                                             
Fund                                                            Percentage of Advisory Fee Payable to the Adviser
- ----                                                            -------------------------------------------------
John Hancock Independence Diversified Core Equity Fund II                              35%


     The  Sub-adviser  Fee for the Fund shall be accrued for each  calendar day,
and the sum of the daily fee accruals shall be paid quarterly to the Sub-adviser
within 30 calendar days of the end of each quarter.  The daily fee accruals will
be computed by multiplying  the fraction of one over the number of calendar days
in the year by the applicable  Sub-adviser  Fee, and multiplying this product by
the net assets of the Fund. The Adviser shall provide the Sub-adviser  with such
information as the Sub-adviser may reasonably request supporting the calculation
of the fees paid to it hereunder.  Fees shall be paid either by wire transfer or
check, as directed by the Sub-adviser.

     If this  Agreement  becomes  effective or  terminates,  or if the manner of
determining  the  applicable  Sub-adviser  Fee  changes,  before  the end of any
quarter,  the fee (if any) for the period from the effective  date to the end of
such quarter or from the beginning of such quarter to the date of termination or
from the  beginning of such quarter to the date of such change,  as the case may
be, shall be pro rated  according to the  proportion  which such period bears to
the full quarter in which such effectiveness or termination or change occurs.


                                      A-8
