The Meeting will be held at the principal  office of the Funds,  101  Huntington

Shareholders, this Proxy Statement and the enclosed form of the proxy will first

BOX 9116, BOSTON, MASSACHUSETTS 02205-9116 OR BY CALLING 1-800-892-9552.

If the  enclosed  form of proxy is properly  executed and returned in time to be

previously executed and returned proxy.

SUMMARY OF VOTING ON PROPOSALS   
     Although  the  Meetings of the Funds are being held jointly and proxies are
being solicited  through the use of this joint proxy statement,  shareholders of
each Fund will vote separately as to proposals  affecting their Fund.  Voting by
shareholders   of  one  Fund  will   have  no   effect   on  any   other   Fund.

- -------------------------------------------------------------------------------
                                       CLASS(ES) OF SHARES OF SUCH
PROPOSAL          AFFECTED FUND(S)     FUND ENTITLED TO VOTE
- ---------  --------------------------  ----------------------------------------
1          All Funds                   Common Shares
2          All Funds                   Common and Preferred Shares
- -------------------------------------------------------------------------------

    With respect to Proposal 1, each of the Common Shares of Premium Dividend I,
Premium Dividend II, Select Dividend, Global Dividend and Preferred Dividend is
entitled to one vote for the election of their respective nominees for election
as Trustees of their respective Fund. No nominee representing the Preferred
Shares of Premium Dividend I, Premium Dividend II, Select Dividend, Global
Dividend or Preferred Dividend is scheduled for election at the Meeting. With
respect to Proposal 2, each of the Common Shares and the Preferred Shares,
voting together as a single class, of each Fund is entitled to one vote for the
ratification of the selection of independent public accountants.

                                  PROPOSAL 1
                             ELECTION OF TRUSTEES
                         (Common Shares of each Fund)

GENERAL
     Each Fund's  Board of Trustees  consists  of thirteen  members.  Under each
Fund's Declaration of Trust,  By-Laws and the Investment Company Act of 1940, as
amended (the  "Investment  Company  Act"),  holders of the Preferred  Shares are
entitled to elect two Trustees and holders of the Common  Shares are entitled to
elect eleven  Trustees,  except in certain  circumstances.  Ms.  Hodsdon and Ms.
McCarter and Messrs.  Boudreau,  Carlin,  Cunningham,  Fretz,  Ladner,  Linbeck,
Pruchansky,  Smith and Toolan  have been  designated  as subject to  election by
holders of the Common Shares of each Fund. Messrs.  Hiser and Scipione have been
designated  as subject to  election by holders of the  Preferred  Shares of each
Fund.

     Each Board of Trustees is divided into three  staggered-term  classes.  Two
such  classes  contain  four  Trustees  each and the third class  contains  five
Trustees. The term of one class expires each year and no term continues for more
than three  years after the  applicable  election.  Each class of Trustees  will
stand for election at the conclusion of their respective  three-year terms. Such
classification may prevent replacement of a majority of the Trustees for up to a
two-year  period.  The foregoing is subject to the  provisions of the Investment
Company Act and the Funds'  By-Laws  which  permit the holders of the  Preferred
Shares to elect the minimum number of additional  Trustees which,  combined with
the two Trustees elected by the holders of the Preferred Shares, would give them
a majority of the Trustees if at any time the dividends on the Preferred  Shares
shall be unpaid in an amount equal to two full years' dividends and would permit
the holders of the Preferred  Shares to continue to be so represented  until all
dividends in arrears shall have been paid or otherwise provided for.

     Each of the nominees for each Fund is currently serving as a Trustee of all
of the  Funds.  Each of the  nominees  and  Trustees  has served on the Board of
Trustees of the Funds since John Hancock  Advisers,  Inc. (the "Adviser") became
the  Funds'  investment  adviser  in May,  1992 or since  the  Fund's  inception
(whichever was later), except that Messrs.  Toolan,  Cunningham and Linbeck have
served on the Board of  Trustees  since June 1992,  December  1994 and  December
1994,  respectively,  and Ms.  Hodsdon has served on the Board of Trustees since
March 1996.  Premium  Dividend I was organized in 1988;  Premium Dividend II was
organized in 1989;  Select  Dividend was organized in 1990;  Global Dividend was
organized in 1992; and Preferred Dividend was organized in 1993.

     A shareholder using the enclosed form of proxy may authorize the proxies to
vote for the nominees  representing  his or her shares or may withhold  from the
proxies authority to vote for the nominees representing his or her shares. If no
contrary instructions are given, the proxies will vote FOR the nominees. Each of
the nominees has consented to his or her  nomination  and has agreed to serve if
elected. If, for any reason, any nominee should not be available for election or
able to serve as a Trustee,  the proxies  will  exercise  their  voting power in
favor of such substitute  nominee, if any, as the Funds' Trustees may designate.
The Funds have no reason to believe  that it will be  necessary  to  designate a
substitute nominee.

PROPOSAL 1 (PREMIUM DIVIDEND I, PREMIUM DIVIDEND II, SELECT DIVIDEND, GLOBAL
DIVIDEND AND PREFERRED DIVIDEND)
     For each Fund,  the terms of Ms.  Hodsdon and Messrs.  Boudreau,  Smith and
Pruchansky expire at the 1998 Annual Meeting of the Funds and they are therefore
the current  nominees for  election;  the terms of Messrs.  Carlin,  Cunningham,
Fretz, Hiser and Toolan expire at the 1999 Annual Meeting;  and the terms of Ms.
McCarter  and Messrs.  Ladner,  Linbeck and  Scipione  expire at the 2000 Annual
Meeting.  The table below  lists the  nominees  for  election as Trustees of the
Funds,  including their principal  occupations for the past five years and other
directorships  held.  The table also lists the  Trustees  who are not  currently
standing for election and whose current terms continue until the annual meetings
in 1999 and 2000, respectively.

VOTE REQUIRED FOR PROPOSAL 1
    The vote of a plurality of the votes cast by the Common Shares of a Fund is
sufficient to elect the nominees of the Common Shares of that Fund.

                                                                  COMMON SHARES

    all voting and investment powers with respect to the shares indicated.
(2) None of the Trustees beneficially owned individually, and the Trustees and
    executive officers of the Funds as a group did not beneficially own, in
    excess of one percent of the outstanding Common Shares of any Fund. None of
    the Trustees or executive officers of the Funds beneficially owned any of
    the Preferred Shares of any Fund as of January 8, 1998.
(3) Trustee representing the holders of the Preferred Shares.

(6) Includes 100 common shares of Premium Dividend I held by Mr. Carlin's
    spouse, and 2,163 common shares held by Carlin Consolidated, Inc.

     Each Board of Trustees held four  meetings  during their Fund's 1997 fiscal
year. No Trustee of any Fund, with the exception of Mr. Carlin and Mr. Scipione,
attended  fewer than 75% of the aggregate of (1) the total number of meetings of
the  Trustees  of the Fund and (2) the  total  number  of  meetings  held by all
committees  of the Trustees on which they served during the period in which they
served in such  capacity.  The Funds hold joint meetings of the Trustees and all
committees.

     Each Fund has an Audit Committee of the Trustees. The Committee members are
Ms. McCarter and Messrs.  Fretz,  Toolan,  Ladner,  Smith,  Pruchansky,  Carlin,
Linbeck,  Cunningham and Hiser.  None of the members of the Audit  Committee are
"interested  persons" as defined in the  Investment  Company  Act  ("Independent
Trustees"). Each Audit Committee held four meetings during its respective Fund's
1997 fiscal year.

     The functions performed by the Audit Committee are to recommend annually to
the Trustees a firm of  independent  certified  public  accountants to audit the
books and  records of the Funds for the  ensuing  year;  to monitor  that firm's
performance;  to review  with the firm the scope and  results  of each audit and
determine the need, if any, to extend audit procedures;  to confer with the firm
and  representatives  of the Funds on matters  concerning  the Funds'  financial
statements  and  reports,  including  the  appropriateness  of their  accounting
practices  and of their  internal  controls  and  procedures;  to  evaluate  the
independence  of  the  firm;  to  review   procedures  to  safeguard   portfolio
securities;  to approve the purchase by the Funds from the firm of all non-audit
services;  to review all fees paid to the firm; to recommend to the Trustees, at
the request of the Funds' officers or Trustees, a resolution of any potential or
actual conflict of interest;  and to facilitate  communication  between the firm
and the Funds' officers and Trustees.

     Each Fund has a special  nominating  committee of the Trustees known as the
Administration  Committee.  The Committee  members are Ms.  McCarter and Messrs.
Fretz, Toolan, Ladner, Smith, Pruchansky, Carlin, Linbeck, Cunningham and Hiser.
All of the members of the  Administration  Committee are  Independent  Trustees.
Each  Administration  Committee held four meetings during its respective  Fund's
1997 fiscal year.

     Included  among  the  functions  of  the  Administration  Committee  is the
selection and nomination for  appointment and election of candidates to serve as
Trustees who are not "interested  persons" as defined in the Investment  Company
Act.  The  Administration  Committee  also  coordinates  with  Trustees  who are
interested  persons in the  selection  and  election of Fund  officers  and will
consider  nominees  recommended by shareholders  to serve as Trustees,  provided
that  shareholders  submit such  recommendations  in compliance  with all of the
pertinent provisions of Rule 14a-8 under the Securities Exchange Act of 1934, as
amended.

COMPLIANCE WITH SECTION 16(A) REPORTING REQUIREMENTS
     Section  16(a) of the  Securities  Exchange  Act of 1934  requires a Fund's
executive  officers,  Trustees  and  persons  who own more than ten percent of a
Fund's shares ("10%  Shareholders")  to file reports of ownership and changes in
ownership  with  the  Securities  and  Exchange  Commission  ("SEC").  Executive
officers,  Trustees,  and 10%  Shareholders  are required by SEC  regulations to
furnish each Fund with copies of all Section 16(a) forms they file. Based solely
on a  review  of  the  copies  of  these  reports  furnished  to the  Funds  and
representations  that no other  reports  were  required  to be filed,  each Fund
believes that during the past fiscal year its executive  officers,  Trustees and

 * The total compensation paid by the John Hancock Fund Complex to the Independent Trustees was $747,750 for the
   calendar year ended December 31, 1997. All the Independent Trustees are Trustees of 32 funds in the John Hancock Fund
   Complex.
** As of December 31, 1997, the value of the aggregate accrued deferred compensation amount from all funds in the John
   Hancock fund complex for Mr. Cunningham was $220,106, for Mr. Hiser was $103,868, for Ms. McCarter was $159,075, for
   Mr. Pruchansky was $68,102, for Mr. Smith was $70,607 and for Mr. Toolan was $281,133 under the John Hancock Deferred
   Compensation Plan for Independent Trustees ("the "Plan"). Under the Plan, an Independent Trustee may elect to have
   his deferred fees invested by a Fund in shares of one or more funds in the John Hancock Fund Complex, and the amount
   paid to the Trustees under the Plan will be determined based upon the performance of such investments. Deferral of
   Trustees" fees does not obligate any Fund to retain the services of any Trustee or obligate any Fund to pay any
   particular level of compensation to the Trustee.

                                  PROPOSAL 2

         RATIFICATION OF SELECTION OF THE INDEPENDENT PUBLIC ACCOUNTANTS

              (Common Shares and Preferred Shares of each Fund)

     The  Trustees  of  each  Fund,  including  a  majority  of the  Independent
Trustees,  have selected Deloitte & Touche,  LLP ("Deloitte & Touche") to act as
independent  public  accountants for the Funds for each Fund's 1998 fiscal year.
The Funds'  current  fiscal year ends are:  Premium  Dividend I - September  30,
1998;  Premium Dividend II - October 31, 1998;  Select Dividend - June 30, 1998;
Global Dividend - July 31, 1998; and Preferred Dividend - May 31, 1998.

     Deloitte & Touche has  advised  the Funds that it has no direct or indirect
financial  interest  in any of the  Funds.  This  selection  is  subject  to the
ratification by the shareholders of the Funds at the Meeting. The enclosed proxy
card provides space for instructions directing the proxies named therein to vote
for,  against,  or abstain from,  ratifying that selection.  A representative of
Deloitte  & Touche is  expected  to be  present  at the  Meeting,  will have the
opportunity to make a statement if the representative  desires to do so and will
be available to respond to appropriate  questions relating to the examination of
the Funds' financial statements.

     The Boards of Trustees, including all the Independent Trustees, unanimously
recommend  that  shareholders  ratify  the  selection  of  Deloitte  & Touche as
independent public accountants of the Funds for each Fund's 1998 fiscal year.

VOTE REQUIRED TO RATIFY THE SELECTION OF INDEPENDENT PUBLIC ACCOUNTANTS
The approval of a "majority" (as described below) of the Common Shares and the
Preferred Shares, voting as a single class, of each Fund is required to ratify
the selection of Deloitte & Touche as such Fund's independent public accountants
for that Fund's 1998 fiscal year.

                                MISCELLANEOUS

SHAREHOLDER PROPOSALS
     Proposals  of  shareholders  intended to be  presented  at a Fund's  annual
meeting to be held in 1999 must be  received  by the Fund at its  offices at 101
Huntington Avenue, Boston,  Massachusetts,  no later than September 25, 1998 for
inclusion  in that Fund's  proxy  statement  and form of proxy  relating to that
meeting.

VOTING; QUORUM; ADJOURNMENT
     The  affirmative  vote of the  holders  of a  plurality  of the shares of a
particular  class of a Fund  present  in person or  represented  by proxy at the
Meeting, assuming a majority of the outstanding shares of that class is present,
is required to elect the nominees  representing  the Common  Shares or Preferred
Shares,  as the case  may be.  The  adoption  by the  shareholders  of a Fund of
Proposal 2 requires  the  affirmative  vote of a majority of the shares which is
defined as the lesser of: (i) 67% or more of the voting  securities  of the Fund
present at the Meeting, if the holders of more than 50% of the Common Shares and
the  Preferred  Shares of that Fund,  voting  together  as a single  class,  are
present or represented by proxy; or (ii) more than 50% of the outstanding Common
Shares and the Preferred Shares of the Fund, voting together as a single class.

     For each Fund, Common Shares and Preferred Shares  represented in person or
by proxy  (including  shares which abstain or do not vote with respect to one or
both of the proposals  presented for  shareholder  approval) will be counted for
purposes of determining whether a quorum is present at the Meeting.  Abstentions
from voting will be treated as shares that are present and  entitled to vote for
purposes of  determining  the number of shares that are present and  entitled to
vote with respect to either proposal, but will not be counted as a vote in favor
of that proposal.  Accordingly,  an abstention  from voting has no effect on the
voting in  determining  whether  Proposal  1 has been  adopted  but has the same
effect as a vote against Proposal 2.

     Although  both of the  proposals  in this proxy  statement  are  considered
routine  matters  on which  brokers  holding  shares in  "street  name" may vote
without instruction under the rules of the New York Stock Exchange,  if a broker
or nominee holding shares in "street name"  nevertheless  indicates on the proxy
that it does not have  discretionary  authority  to vote as to either  proposal,
those shares will not be  considered  as present and entitled to vote as to that
proposal.  Accordingly,  a "broker  non-vote"  has no  effect  on the  voting in
determining  whether Proposal 1 has been adopted and has no effect on the voting
in determining  whether  Proposal 2 has been adopted pursuant to item (i) above,
provided that the holders of more than 50% of the outstanding  shares (excluding
the "broker  non-votes")  are present or  represented  by proxy.  However,  with
respect to determining whether Proposal 2 has been adopted pursuant to item (ii)
above,  because  shares  represented  by  a  "broker  non-vote"  are  considered
outstanding  shares,  a "broker  non-vote" has the same effect as a vote against
such proposal.

     While,  as noted above,  both of the proposals in this proxy  statement are
routine, for non-routine  matters,  brokers that are member organizations of the
New York Stock Exchange may,  pursuant to a rule in the New York Stock Exchange,
vote Preferred  Shares for which they have not received  voting  instructions in
proportion to Preferred Shares for which they have received voting instructions.
With  respect  to each  Proposal,  a  broker  may  only  vote  Preferred  Shares
proportionally  if (i) a minimum of 30% of the outstanding  Preferred  Shares of
the Fund have been voted, (ii) less than 10% of the outstanding Preferred shares
of the Fund voted against the  proposal,  (iii) with respect to Proposal 2 only,
the shareholders of the Common Shares of the Fund have approved the Proposal and
(iv) a  majority  of the  Independent  Trustees  of the Fund have  approved  the
Proposal.  At a meeting held on December 3, 1997, a majority of the  Independent
Trustees  of  each  Fund  approved  both of the  Proposals  being  submitted  to
shareholders at the Meeting.  Preferred Shares voted  proportionally  by brokers
will be counted as present and  entitled to vote at the Meeting for  purposes of
establishing a quorum.

     In the event that at the time any session of any Meeting is called to order
and a quorum is not present in person or by proxy,  the persons named as proxies
may vote those  proxies  which have been  received to adjourn  such Meeting to a
later date. In the event that a quorum is present at any Meeting but  sufficient
votes in favor of Proposal 2 and FOR the  nominees  set forth in Proposal 1 have
not  been  received,  the  persons  named as  proxies  may  propose  one or more
adjournments  of such  Meeting to permit  further  solicitation  of proxies with
respect to such proposal. Any adjournment will require the affirmative vote of a
majority  of the  shares  present  in person or by proxy at the  session  of the
Meeting to be  adjourned.  The persons  named as proxies will vote those proxies
which they are  entitled to vote in favor of any such  proposal in favor of such
adjournment  and will vote those  proxies  required to be voted against any such
proposal  against  such  adjournment.  With  respect  to any Fund's  Meeting,  a
shareholder  vote  may be taken  on one or both of the  proposals  prior to such
adjournment if sufficient  votes for the proposal's  approval have been received
and it is otherwise appropriate.

EXPENSES AND METHODS OF SOLICITATION
    The costs of the Meeting, including the solicitation of proxies, will be
paid by the Funds. Persons holding shares as nominees will be reimbursed by the
relevant Fund, upon request, for their reasonable expenses in sending soliciting
material to the principals of the accounts. In addition to the solicitation of
proxies by mail, Trustees, officers and employees of the Funds or of the Funds'
investment adviser may solicit proxies in person or by telephone. John Hancock
Advisers, Inc., 101 Huntington Avenue, Boston Massachusetts 02199-7603, serves
as each Fund's investment adviser and serves as the administrator of Premium
Dividend I, Premium Dividend II, Select Dividend and Preferred Dividend. John
Hancock Advisers International Limited, 34 Dover Street, London, England, serves
as Global Dividend's investment subadviser. Mitchell Hutchins Asset Management,
Inc., 1285 Avenue of the Americas, New York, New York, serves as Global
Dividend's administrator. The firm Corporate Investor Communications, Inc. has
been retained to assist in the solicitation of proxies at a cost of
approximately $21,500.

OTHER MATTERS
     The  management of the Funds knows of no business to be brought  before the
Meeting except as mentioned above. If, however,  any other matters were properly
to come before the  Meeting,  the persons  named in the  enclosed  form of proxy
intend to vote on such matters in accordance  with their best  judgment.  If any
shareholders  desire  additional  information  about the  matters  proposed  for
action, the management will provide further information.

     The Meeting is scheduled as a joint meeting of the respective  shareholders
of the Funds because the shareholders of all the Funds are generally expected to
consider and vote on similar  matters.  The Boards of Trustees of the Funds have
determined  that the use of this joint Proxy Statement for the Meeting is in the
best  interest of each Fund's  shareholders.  In the event that any  shareholder
present at the Meeting  objects to the holding of a joint  meeting and moves for
an  adjournment of his or her  particular  Fund's Meeting to a time  immediately
after the  Meeting  so that his or her  particular  Fund's  Meeting  may be held
separately, the persons named as proxies will vote in favor of such adjournment.
Shareholders of each Fund will vote separately on both of the Proposals relating
to their Fund, and an unfavorable  vote on a Proposal by the shareholders of one
Fund will not affect the  implementation of such Proposal by another Fund if the
Proposal is approved by the shareholders of that Fund.

            IT IS IMPORTANT THAT PROXIES BE RETURNED PROMPTLY
