DISTRIBUTION AGREEMENT

     AGREEMENT, dated as of May 1, 2004, by and between John Hancock Variable
Series Trust I (the "Trust"), on behalf of each of the one or more portfolios of
the Trust listed in Appendix A (each such portfolio a "Participating Fund"), and
Manulife Financial Securities LLC (the "Series Distributor").

     WHEREAS, the Trust is a Massachusetts business trust which is registered as
an open-end investment company under the Investment Company Act of 1940 (the
"1940 Act") and sells its shares to insurance company separate accounts to which
net premiums, contributions and considerations under variable insurance and
annuity products ("Variable Products") are allocated for investment in the Trust
("Eligible Separate Accounts");

     WHEREAS, the Trust has divided its shares into series, each representing a
different Fund, has further divided the shares of each Fund into three classes
of shares (NAV Class, Series I and Series II), and has adopted a plan with
respect to the Series I and shares (collectively, the "Rule 12b-1 Classes") of
each Participating Fund pursuant to Rule 12b-1 under the 1940 Act (the "Rule
12b-1 Plan");

     WHEREAS, The Trust also has adopted a related plan under Rule 18f-3 (the
"Rule 18f-3 Plan") under the 1940 Act;

     WHEREAS, the Rule 12b-1 Plan and the Rule 18f-3 Plan (together, the
"Plans") provide that the Rule 12b-1 Classes of a Participating Fund of the
Trust may be assessed with fees at rates specified in the Rule 12b-1 Plan;

     WHEREAS, the Trust desires the Series Distributor to act as a principal
underwriter with respect to Series I and Series II shares of the Participating
Fund; and

     WHEREAS, the Series Distributor is registered as a broker-dealer under the
Securities Exchange Act of 1934 and is a member of the National Association of
Securities Dealers, Inc. ("NASD");

     NOW, THEREFORE, the Trust and the Series Distributor agree as follows:

   1.   Appointment and Acceptance

     The Trust hereby appoints the Series Distributor as principal underwriter
and distributor of the shares of the Funds, and the Series Distributor hereby
accepts that appointment; provided, however, that this appointment shall extend
only to sales to Eligible Separate Accounts of Manufacturers Life Insurance
Company (U.S.A.) (hereinafter, "Manufacturers USA") and Manufacturers Life
Insurance Company of New York (hereinafter "Manufacturers New York") and
Eligible Separate Accounts of such other insurance companies as the Trust shall
have authorized in writing.



   2.   Rule 12b-1 Compensation to the Series Distributor

     2.1  Each Participating Fund will pay Rule 12b-1 compensation to the Series
Distributor up to the net effective annual rate indicated below for each Rule
12b-1 Class of the Fund's shares:

                           Series I               .40%

                           Series II              .60%

These fees shall be accrued daily and payable monthly based on the current net
assets of the applicable Rule 12b-1 Class of a Participating Fund's shares as to
which the Series Distributor has served as principal underwriter (or that are
exchanged or converted in any reorganization for other shares of any fund as to
which the Series Distributor served as a principal underwriter). "Current net
assets" for purposes of computing the amount of Rule 12b-1 Fee accrued with
respect to any class of a Participating Fund's shares shall mean the net assets
for that class of that Fund's shares for the most recent preceding day for which
the net assets for that Fund were computed. The fee shall be payable as soon as
possible after the last day of each calendar month. In the case of termination
of this Agreement as to any class of a Participating Fund, the fees accrued for
such shares through the date of termination will be paid. The Series Distributor
waives any claim for Rule 12b-1 Fees in excess of the rates specified above.

     2.2. The Series Distributor shall be entitled to no compensation for
services rendered and expenses borne as principal underwriter and distributor
other then as specified in this Section 2.

   3.   Authority of Series Distributor

     Without limiting the foregoing, in its capacity as principal underwriter
and distributor, and acting as principal and not as agent for the Trust, the
Series Distributor is authorized, from time to time, to enter into separate
agreements with Manufacturers USA, with Manufacturers New York and with other
insurance companies authorized pursuant to Section 1 hereof, and with any broker
or other intermediary through whom a transaction is effected as to which the
Series Distributor is acting as principal underwriter hereunder, which
agreements may provide how much compensation out of any related Rule 12b-1
payments the Series Distributor will pay to any such company or person and how
much of such payments, if any, will be retained by the Series Distributor, in
each case, however, on terms and conditions not inconsistent with this Agreement
or the Rule 12b-1 Plan.

   4.   Compliance with Plans

     Each party hereto agrees to comply with each provision of the Rule 12b-1
Plan or the Rule 18f-3 Plan (as they may be amended from time to time) that is
applicable to that party. The Trust agrees to advise the Series Distributor of
any change in either Plan.

                                       2



   5.   Furnishing Certain Information

     Without limitation of any other provision of this Agreement, the parties
hereto agree, upon request, to furnish to the Trustees of the Trust such
information available to them that may be reasonably necessary (a) to evaluate
the Rule 18f-3 Plan (or any successor or proposed successor to that Plan) in
connection with any vote referred to in Rule 18f-3(d) or (b) to an informed
determination of whether the Rule 12b-1 Plan (or any successor or proposed
successor to such Plan), or any agreement related to such Plan, or any revisions
thereto, should be approved or continued. Also, the Series Distributor shall
furnish to the Trust, at least quarterly, reports as to the sales of Trust
shares made pursuant to this Agreement. Such reports shall be in writing and
include information on the amounts of Rule 12b-1 Fees expended for each Rule
12b-1 Class of each Participating Fund, the recipients of the Rule 12b-1 Fees
expended by the Series Distributor or by affiliated and unaffiliated insurance
companies, and the purposes for which such amounts were expended. Series
Distributor hereby authorizes John Hancock Life Insurance Company to deliver
these reports on the Series Distributor's behalf, if the Trustees of the Trust
so request.

     These reports shall also include such information about expense
apportionments or allocations, fee or expense waivers for any classes, and
differences in shareholder voting patterns as among different classes of the
same Participating Fund, and other pertinent matters as the Trustees may
reasonably request.

   6.   Purchases and Redemptions of Shares
