                      AGREEMENT AND PLAN OF REORGANIZATION

THIS AGREEMENT AND PLAN OF REORGANIZATION (the "Agreement") is made this 26th
day of February, 2003, by and between John Hancock Variable Series Trust I, a
Massachusetts business trust (the "Trust II"), with its principal place of
business at John Hancock Place, P.O. Box 111, Boston, Massachusetts 02117, on
behalf of its series _______________________ (the "Acquiring Fund") and John
Hancock Declaration Trust, a Massachusetts business trust (the "Trust") with its
principal place of business at 101 Huntington Avenue, Boston, Massachusetts
02199, on behalf of its series _________________________ (the "Acquired Fund").
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: (1) the transfer of
all of the assets of the Acquired Fund to the Acquiring Fund in exchange solely
for (A) the issuance of shares of beneficial interest of the Acquiring Fund (the
"Acquiring Fund Shares") to the Acquired Fund and (B) the assumption by the
Acquiring Fund of all of the liabilities of the Acquired Fund, followed by (2)
the distribution by the Acquired Fund, on or promptly after the Closing Date
hereinafter referred to, of the Acquiring Fund Shares to the shareholders of the
Acquired Fund in liquidation and termination of the Acquired Fund as provided
herein, all upon the terms and conditions set forth in this Agreement.

In consideration of the premises of the covenants and agreements hereinafter set
forth, the parties hereto covenant and agree as follows:

1.   TRANSFER OF ASSETS OF THE ACQUIRED FUND IN EXCHANGE FOR ASSUMPTION OF
     LIABILITIES AND ISSUANCE OF ACQUIRING FUND SHARES; LIQUIDATION OF THE
     ACQUIRED FUND

1.1    The Acquired Fund will transfer all of its assets (consisting, without
       limitation, of portfolio securities and instruments, dividends and
       interest receivables, cash and other assets), as set forth in the
       statement of assets and liabilities referred to in Paragraph 7.2 hereof
       (the "Statement of Assets and Liabilities"), to the Acquiring Fund free
       and clear of all liens and encumbrances, except as otherwise provided
       herein, in exchange for (i) the assumption by the Acquiring Fund of the
       known and unknown liabilities of the Acquired Fund, including the
       liabilities set forth in the Statement of Assets and Liabilities (the
       "Acquired Fund Liabilities"), which shall be assigned and transferred to
       the Acquiring Fund by the Acquired Fund and assumed by the Acquiring
       Fund, and (ii) delivery by the Acquiring Fund to the Acquired Fund, for
       distribution pro rata by the Acquired Fund to its shareholders in
       proportion to their respective ownership of shares of beneficial interest
       of the Acquired Fund, as of the close of business on April 25, 2003
       [April 30, 2003 for V.A. Financial Industries Fund] (the "Closing Date"),
       of a number of the Acquiring Fund Shares having an aggregate net asset
       value equal to the value of the assets, less such liabilities (herein
       referred to as the "net value of the assets") 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 with respect to the Acquiring Fund shall be provided by
       State Street Bank and Trust Company (the "Acquiring Fund's Custodian"),
       as custodian and pricing agent for the Acquiring Fund and, and with
       respect to the Acquired Fund by the Bank of New York (the "Acquired
       Fund's Custodian).

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 of Acquiring Fund Shares due
       such shareholders. The Acquiring Fund shall not issue certificates
       representing Acquiring Fund Shares in connection with such exchange.

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

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

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

1.8    Any reporting responsibility of the 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 Acquiring Fund Shares and the net values of
       the assets and liabilities of the Acquired Fund 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 Acquiring Fund
       Shares shall be computed by the Acquiring Fund's Custodian in the manner
       set forth in the Acquiring Fund's Declaration of Trust as amended and
       restated (the "Declaration"), or By-Laws and the Acquiring Fund's
       then-current prospectus and statement of additional information and shall
       be computed in each case to not fewer than four decimal places. The net
       values of the assets of the Acquired Fund to be transferred shall be
       computed by the Acquired Fund's Custodian by calculating the value of the
       assets transferred by the Acquired Fund and by subtracting therefrom the
       amount of the liabilities 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 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 less the
       liabilities assumed by the Acquiring Fund, by the Acquiring Fund's net
       asset value per share, all as determined in accordance with Paragraph 2.1
       hereof.

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

3.   CLOSING AND CLOSING DATE

3.1    The Closing Date shall be April 25, 2003 [April 30, 2003 for V.A.
       Financial Industries Fund] or such other date on or before December 31,
       2003 as the parties may agree. The Closing shall be held as of 5:00 p.m.
       at the offices of 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 Acquired Fund's Custodian as record holder for the Acquired Fund
       shall be presented by the Acquired Fund to the Acquiring Fund's Custodian
       for examination no later than five 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 Acquiring Fund's 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 Acquired Fund's Custodian in book-entry form on
       behalf of the Acquired Fund shall be delivered to the Acquiring Fund by
       the Acquiring Fund's Custodian by recording the transfer of beneficial
       ownership thereof on its records. The cash delivered shall be in the form
       of currency or by the Acquiring Fund's Custodian crediting the Acquiring
       Fund's account maintained with the Acquiring Fund's 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 December 31, 2003, 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 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.

        body which materially and adversely affects the Acquired Fund's business
        or its ability to consummate the transactions herein contemplated;

    (e) The Acquired Fund has no material contracts or other commitments (other
        than this Agreement or agreements for the purchase of securities entered

to prohibit the parties from amending this Agreement to change the Closing Date.

      This certificate is being delivered in connection with the transaction to
be effected pursuant to the Agreement and Plan of Reorganization (the
"Agreement") made as of ____________, 2003 between John Hancock Variable Series
Trust I on behalf of __________________ ("Acquiring Fund") and John Hancock

the Agreement, Acquiring Fund will acquire all of the assets of Acquired Fund in
exchange solely for (i) the assumption by Acquiring Fund of certain liabilities
of Acquired Fund (the "Acquired Fund Liabilities") and (ii) the issuance of
shares of beneficial interest of Acquiring Fund (the "Acquiring Fund Shares") to
Acquired Fund, followed by the distribution by Acquired Fund, in liquidation of
Acquired Fund, of the Acquiring Fund Shares to the shareholders of Acquired Fund
and the termination of Acquired Fund (the foregoing together constituting the
"transaction").

      The undersigned officer of John Hancock Variable Series Trust I, after
consulting with its tax advisors regarding the meaning of and factual support
for the following representations, on behalf of Acquiring Fund, hereby certifies
and represents that the following statements are true, complete and correct and
will be true, complete and correct on the date of the transaction and thereafter
as relevant. Unless otherwise indicated, all capitalized terms used but not
defined herein shall have the meaning ascribed to them in the Agreement.

     1. Acquiring Fund is a series of the John Hancock  Variable Series Trust I,
a  business  trust   established   under  the  laws  of  the   Commonwealth   of
Massachusetts.

     2. Neither  Acquiring  Fund nor any person  treated as related to Acquiring
Fund under Treasury  Regulation  Section  1.368-1(e)(3)  or by virtue of being a
partnership of which Acquiring Fund or a related person is a partner (a "Related
Person") has any plan or intention to redeem or otherwise  reacquire  any of the
Acquiring  Fund  Shares  received  by  shareholders  of  Acquired  Fund  in  the
transaction  except in the  ordinary  course of  Acquiring  Fund's  business  in
connection  with its legal  obligation  under  Section  22(e) of the  Investment
Company Act of 1940, as amended,  as a registered open-end investment company to
redeem its own shares (which  obligation is not in connection with,  modified in
connection with, or in any way related to the transaction).

     3.  After the  transaction,  Acquiring  Fund  will  continue  the  historic
business  of  Acquired  Fund or will  use all or a  significant  portion  of the
historic assets of Acquired Fund in a business. For this purpose, Acquiring Fund
shall be treated as  conducting  the  business and holding the assets of certain
related entities, as described in Treasury Regulation Section 1.368-1(d)(4).




     4. Acquiring Fund has no plan or intention to sell or otherwise  dispose of
any assets of Acquired Fund acquired in the transaction, except for dispositions
made in the ordinary course of its business.

     5. Each of the funds of the John Hancock Variable Series Trust I, including
Acquiring  Fund, will bear a portion of the expenses of the Acquired Fund solely
and directly  related to the  transaction  in accordance  with Rev. Rul.  73-54,
1973-1 C.B. 187. The  shareholders of Acquiring Fund and Acquired Fund will bear
their respective expenses, if any, in connection with the transaction.

     6. There is no indebtedness between Acquiring Fund and Acquired Fund.

     7.  Acquiring  Fund has  elected to be treated  as a  regulated  investment
company  under  Subchapter  M of the Code,  has  qualified  for the  special tax
treatment  afforded  regulated  investment  companies  under  the  Code for each
taxable year since inception, qualifies for such treatment as of the date of the
transaction, and intends to qualify for such treatment after the transaction.

     8. Acquiring Fund meets the requirements of a regulated  investment company
as defined in Section 368(a)(2)(F) of the Code.

     9. Acquiring Fund is not under the jurisdiction of a court in a Title 11 or
similar case within the meaning of Section 368(a)(3)(A) of the Code.

indirectly, any shares of Acquired Fund.

     11.  Acquiring  Fund  will not pay  cash in lieu of  fractional  shares  in
connection with the transaction.

     12.  As of the  date of the  transaction,  the  fair  market  value  of the
Acquiring  Fund  Shares  issued to Acquired  Fund in exchange  for the assets of
Acquired Fund will be approximately equal to the fair market value of the assets
of Acquired Fund received by Acquiring Fund, minus the Acquired Fund Liabilities
assumed by Acquiring Fund.  Acquiring Fund will not furnish any consideration in
connection  with the  acquisition  of  Acquired  Fund's  assets  other  than the
assumption  of such Acquired Fund  Liabilities,  the issuance of such  Acquiring
Fund Shares, and the payment of a portion of Acquired Fund's expenses solely and
directly  related to the transaction in accordance with Rev. Rul. 73-54,  1973-1
C.B. 187.

     13.  Acquired Fund  shareholders  will be in control (within the meaning of
Sections  368(a)(2)(H)(i)  and 304(c) of the Code,  which  provide  that control
means the  ownership  of shares  possessing  at least 50% of the total  combined
voting  power of all classes of shares that are entitled to vote or at least 50%
of the  total  value of shares  of all  classes)  of  Acquiring  Fund  after the
transaction.




     14. The principal  business  purposes of the transaction are to combine the
assets of Acquiring Fund and Acquired Fund in order to improve  distribution and
