Large Cap Growth B Fund (FORMERLY LARGE CAP AGGRESSIVE GROWTH FUND)
Independence Investment LLC                                 M. Lapman/J. Forelli
- --------------------------------------------------------------------------------

..    In 2003, the Fund returned 31.72%, outperforming its benchmark, the Russell
     1000 Growth Index.

..    Independence Investment LLC assumed management of the Fund effective
     December 15th. Independence implemented an investment strategy for the Fund
     that is substantially the same as the investment strategy it now employs
     for the Large Cap Growth Fund. Under that strategy, the Fund will invest
     primarily in large cap growth stocks.

..    The Fund outperformed its benchmark primarily due to favorable stock
     selection and sector allocation decisions. Stock selection was most
     favorable in the health care and industrial sectors, while the Fund's
     underweight to health care was also a major contributor.

..    The Fund's exposure to information technology was the largest contributor
     to absolute performance.

..    The manager uses both fundamental equity research and quantitative
     portfolio construction to identify stocks having both favorable valuations
     and improving earnings growth prospects. The Fund is broadly diversified
     across sectors with sector weights similar to the benchmark.

*    Total returns are for the period ended December 31, 2003. Returns represent
     past performance, assume reinvestment of all distributions and are not
     indicative of future performance. Investment returns and principal value of
     fund shares will fluctuate so that shares, when redeemed, may be worth more
     or less than their original cost. The performance of the fund on this page
     is reported net of Trust level charges (i.e. investment management fees and
     operating expenses). It does not reflect expenses and charges of the
     applicable separate accounts and variable products, all of which vary to a
     considerable extent and are described in your product prospectus. There are
     additional risks associated with a nondiversified fund, as outlined in the
     current prospectus. Performance would be lower if expenses and charges of
     the separate accounts and products were reflected.

NOTE A--ORGANIZATION

     John Hancock Large Cap Growth B Fund, (formerly Large Cap Aggressive
Growth), (the "Fund") is a diversified series of John Hancock Variable Series
Trust I (the "Trust"), an open-end investment management company registered
under the Investment Company Act of 1940. The Trust is organized as a
Massachusetts business trust and consists of thirty different funds as of
December 31, 2003. The results of this Fund are included in this report. The
results of the other Funds in the Trust are presented under separate cover. The
Trust may add or delete Funds in the future to accommodate various investment
objectives. The Trust has issued shares of beneficial interest exclusively to
John Hancock Variable Life Account U ("JHVLAU"), John Hancock Variable Life
Account V ("JHVLAV"), John Hancock Variable Life Account S ("JHVLAS"), and John
Hancock Variable Annuity Account I ("JHVAAI") to fund policies and contracts
issued by the John Hancock Variable Life Insurance Company ("JHVLICO"), and to
John Hancock Variable Annuity Account U ("JHVAAU"), John Hancock Variable
Annuity Account V ("JHVAAV"), John Hancock Variable Life Account UV ("JHVLAUV"),
John Hancock Variable Annuity Account H ("JHVAAH"), and John Hancock Variable
Annuity Account JF ("JHVAAJF") to fund contracts and policies issued by John
Hancock Life Insurance Company ("John Hancock" or "JHLICO"), to John Hancock
Variable Life Account PPM-1 ("PPM-1"), and to John Hancock Variable Life Account
PPM-2 ("PPM-2").

NOTE B--ACCOUNTING POLICIES

     Valuation of investments: Common stocks and other such securities traded on
national exchanges are normally valued on the basis of closing prices.
Securities traded in the over-the-counter market and securities with no sales on
the day of valuation are normally valued at their last available bid price.

     Short-term investments, with a maturity not to exceed 60 days, are valued
at amortized cost, which approximates market value.

     Investment securities for which no current market quotations are readily
available, including certain foreign securities, when held by the Fund, are
valued at fair value as determined in good faith by the Board of Trustees.
Investment security transactions are recorded on the date of purchase or sale.

     Repurchase agreements: The Fund may enter into repurchase agreements which
are contracts under which the Fund would acquire a security for a relatively
short period (usually not more than 7 days) subject to the obligation of the
seller to repurchase and the Fund to resell such security at a fixed time and
price (representing the Fund's cost plus interest). The Fund will enter into
repurchase agreements only with member banks of the Federal Reserve System and
with "primary dealers" in United States Government Securities. The underlying
securities, which represent the collateral of the agreement, must be marked to
market daily to ensure that each repurchase agreement is fully collateralized at
all times. The Fund will not invest more than 10% of its net assets in
repurchase agreements maturing in more than 7 days.

     Joint trading account: Pursuant to an exemptive order issued by the
Securities and Exchange Commission, the order permits the Fund to pool daily
uninvested cash balances into a joint account for the purpose of investing the
cash balances in short-term repurchase agreements, commercial paper and other
short-term investments which in no event will have a maturity in excess of 7
days. Joint account holdings as of December 31, 2003 are as follows:

Name of Issuer                                     Market Value

NOTE B--ACCOUNTING POLICIES--Continued

     In addition, from the period November 1, 2003 through December 31, 2003,
the Fund incurred no net realized capital losses.

     Dividends, Interest and Distributions: Dividend income is recorded on the
ex-dividend date and interest income is recorded on the accrual basis. Dividend
income for the Fund is shown net of foreign taxes withheld of $3. Realized gains
and losses from security transactions are determined on the basis of identified
cost.

     Dividends of net investment income will be declared and distributed monthly
by the Fund. The Fund will distribute all of its net realized capital gains
annually, at the end of its fiscal year.

     Estimates: The preparation of the financial statements in conformity with
accounting principles generally accepted in the United States of America
requires management to make estimates and assumptions that affect the reported
amounts of assets and liabilities and disclosure of contingent assets and
liabilities at the date of the financial statements and the reported amounts of
revenues and expenses during the reporting period. Actual results could differ
from those estimates.

NOTE C--INVESTMENT ADVISORY AGREEMENT AND OTHER TRANSACTIONS WITH AFFILIATES

     On February 5, 2003, the Board of Trustees of the Trust renewed its
Investment Advisory Agreement with John Hancock. For its services, John Hancock
receives monthly compensation at the following rate on an annual basis of the
Fund's net assets:

                         Between
                    $10 Million and   Excess Over
First $10 Million     $20 Million     $20 Million
- -----------------   ---------------   -----------
      1.00%              0.875%          0.75%

     In the event that normal operating expenses of the Fund, exclusive of
investment advisory fees, taxes, interest, brokerage commissions and
extraordinary expenses, shall exceed 0.10% of the Fund's daily net asset value,
John Hancock and JHVLICO will reimburse the Fund for such excess. Accordingly,
for the year ended December 31, 2003, the reimbursements paid from John Hancock
and JHVLICO were $1 to the Fund.

     As of December 15, 2003, John Hancock has entered into a Sub-Advisory
Agreement with Janus Capital Corp., with respect to the Fund. Janus Capital
Corp. is an affiliate of John Hancock, and under its supervision, is responsible
for the day-to-day investment management of the Fund.

     Signator Investors, Inc., a wholly owned subsidiary of John Hancock is the
principal underwriter and transfer agent of the Trust. Certain officers and
trustees of the Trust are officers and directors of JHVLICO, JHVLAU, JHVLAV,
JHV-LAS, JHVAAI, JHVLAUV, JHVAAV, JHVAAU, JHVAAH, JHVAAJF, PPM-1, and PPM-2, and
some are also officers of John Hancock. Fees for independent trustees are paid
by the Trust.

NOTE D--INVESTMENT TRANSACTIONS

     Purchases and proceeds from sales and maturities of investments, excluding
short-term securities and obligations of the U.S. government, for the Fund for
the year ended December 31, 2003 were as follows:

Purchases   Sales and Maturities
- ---------   --------------------
 $56,914           $57,665

     The identified cost of investments owned by the Fund (including earned
discount on corporate short-term notes, and commercial paper) and their
respective gross unrealized appreciation and depreciation for Federal income tax
purposes at December 31, 2003 were as follows:

Identified    Unrealized     Unrealized    Net Unrealized
   Cost      Appreciation   Depreciation    Appreciation
- ----------   ------------   ------------   --------------
  $28,642       $2,005          $(44)           $1,961

     Distribution of Income and Gains: Distributions of net investment income,
if any, are made at least annually. Net realized gains from investment
transactions, in excess of available capital loss carryforwards, would be
taxable to the Fund if not distributed, and, therefore, will be distributed to
shareholders at least annually. Earnings and profits distributed to shareholders
on redemption of fund shares may be utilized by the Fund, to the extent
permissible, as part of the Fund's dividends-paid deduction on its federal
income tax return.

     The timing and characterization of certain income and capital gains
distributions are determined annually in accordance with federal tax
regulations. As a result, net investment income (loss) and net realized gain
(loss) on investment transactions for a reporting period may differ
significantly from distributions during such period. These differences primarily
relate to certain securities sold at a loss. Additionally, as a result, net
investment income (loss) and net realized gain (loss) on investment transactions
for a reporting period may differ significantly from distributions during such
period. Accordingly, the Fund may periodically make reclassifications among
certain of its capital accounts without impacting the net asset value of the
Fund.

     At December 31, 2003, the Fund's components of distributable earnings on a
tax basis were as follows:

Undistributed    Undistributed
  Ordinary      Net Long-Term-    Capital Loss   Net Unrealized
   Income        Capital Gain    Carryforwards    Appreciation
- -------------   --------------   -------------   --------------
     $--              $--           $15,208           $1,961

     In addition, the tax character of distributions paid by the Fund are
summarized as follows:

       Distributions from     Distributions from
Year     Ordinary Income    Long-Term Capital Gain   Return of Capital
- ----   ------------------   ----------------------   -----------------
2003        $822                     $--                  $3,255
2002          --                      --                      --

     Included in the Fund's 2003 distributions from ordinary income is $822 in
excess of investment company taxable income, which in accordance with applicable
US tax law, is taxable to shareholders as ordinary income distributions.

     *Trustee who is an "interested person" as defined in the 1940 Act, due to
her position with John Hancock Life Insurance Company (or its affiliates), the
ultimate controlling parent of the investment advisor.

     Because the Trust does not hold regular annual shareholders meetings, each
Trustee holds office for an indefinite term until his successor is duly elected
and qualified or until he dies, retires, resigns, is removed or becomes
disqualified. None of the Trustees is a director of other complexes except noted
above.



                REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS

To the Contractowners, Policyholders, and
Board of Trustees of
John Hancock Variable Series Trust I

     We have audited the accompanying statement of assets and liabilities,
including the schedule of investments, of the Large Cap Growth B Fund (formerly,
Large Cap Aggressive Growth Fund) (a portfolio included in the series of John
Hancock Variable Series Trust I {the "Trust"}) as of December 31, 2003, and the
related statement of operations for the year then ended, the statements of
changes in net assets for each of the two years in the period then ended, and
the financial highlights for each of the five years in the period then ended.
These financial statements and financial highlights are the responsibility of
the Trust's management. Our responsibility is to express an opinion on these
financial statements and financial highlights based on our audits.

     We conducted our audits in accordance with auditing standards generally
accepted in the United States. Those standards require that we plan and perform
the audit to obtain reasonable assurance about whether the financial statements
and financial highlights are free of material misstatement. An audit includes
examining, on a test basis, evidence supporting the amounts and disclosures in
the financial statements. Our procedures included confirmation of securities
owned as of December 31, 2003, by correspondence with the custodian and brokers,
or by other appropriate auditing procedures where replies from brokers were not
received. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.

     In our opinion, the financial statements and financial highlights referred
to above present fairly, in all material respects, the financial position of the
Large Cap Growth B Fund of John Hancock Variable Series Trust I at December 31,
2003, the results of its operations for the year then ended, the changes in its
net assets for each of the two years in the period then ended, and the financial
highlights for each of the five years in the period then ended, in conformity
with accounting principles generally accepted in the United States.

The John Hancock Variable Series Trust I consists of funds used as investment
options for various John Hancock variable life and variable annuity contracts.
Investors are not able to invest directly in the John Hancock Variable Series
Trust I.

If the total investment return for any fund for any given year appears unusually
high, the return may be attributable to unusually favorable market conditions
which will probably not be sustainable. For instance, a high total investment
return may reflect participation in IPOs, "hot" industries (e.g.,
internet-related companies), private placements, and/or leveraging investment
techniques during the period indicated. There is no assurance that any of those
methods, or any other investment technique will continue to have the same impact
on the fund's total investment returns.

All of the funds (except bond funds and equity index funds) may participate in
initial public offerings (IPOs). Under certain market conditions, such
participation could significantly improve a fund's total investment return.
There is no assurance that such market conditions will continue and provide the
same favorable impact on future investment returns.

Please refer to the prospectus for your product for additional information about
the investment options available. Variable life insurance and variable annuities
are sold by prospectus. These reports may be used as sales literature when
preceeded or accompanied by the funds' prospectus, which detail charges,
investment objectives, and operating policies.

Insurance products are issued by John Hancock Life Insurance Company, or John
Hancock Variable Life Insurance Company* (*not licensed in New York), Boston, MA
02117. Securities products are distributed by Signator Investors, Inc., Member
NASD, SIPC, 197 Clarendon Street, Boston, MA 02116.
