subaccount will be invested in a corresponding Portfolio of John Hancock
Variable Series Trust I ("Fund"), a "series type" mutual fund advised by John

part of the general account of John Hancock Variable Life Insurance Company
("JHVLICO").

  This prospectus sets forth concisely information about the Account that a

1The annual contract fee is deducted only on Contracts having an Accumulated
 Value of less than $10,000. The contract fee is deducted at the beginning of
 each Contract year after the first and at a full surrender during a Contract
 Year. The contract fee is assessed only during the Accumulation Period. In the
 following Examples, the annual contract fee has been expressed as an annual
 percentage of assets based on past experience concerning Contract fees
 collected on other variable annuity contracts using the same Contract fee
 provision. The Company reserves the right to increase the annual Contract Fee
 up to $50, subject to applicable state regulations.
2John Hancock reimburses a Portfolio when the Portfolio's other fund expenses
 exceed 0.25% of its average daily net asset value.

EXAMPLES

  The following examples should not be considered representations of past or
future expenses; actual expenses may be greater than or less than those shown.
    

  If you surrender or annuitize your Contract at the end of the applicable time
period, you would pay the following current expenses on a $1,000 investment,
assuming 5% annual return on assets:

* Commencement of operations

    


                                  SPECIAL TERMS

  As used in this prospectus, the following terms have the indicated meanings:

ACCUMULATION SHARE: a unit of measurement used in determining the value of a
Contract prior to the commencement of annuity payments or, if earlier, contract
lapse. The value of an Accumulation Share for each subaccount will reflect the
investment performance of that subaccount and will vary in dollar amount.

ACCUMULATED VALUE OF A CONTRACT: total value of the Accumulation Shares in that
Contract plus the Fixed Account Value of that Contract, if any.

ANNUITANT: the person on whose life the Contract is issued.

ANNUITY OPTION: the provisions under which a series of annuity payments is made
to the Annuitant or other payee, such as the Life Annuity with Ten Years
Certain.

ANNUITY UNIT: a unit of measurement used in determining the amount of each
variable annuity payment. The value of an Annuity Unit for each subaccount will
depend upon the assumed investment rate and the investment performance of that
subaccount and will vary in dollar amount.

ANNUITY DIRECT DEPOSIT PROGRAM: a program pursuant to which purchase payments
are automatically paid from the Owner's checking account on a specified day each
month.

BENEFICIARY: the person who receives the proceeds in the event of the death of
the Owner or the Annuitant.

CODE: The Internal Revenue Code of 1986, as amended.

CONTRACT YEAR: a period between anniversaries of the date of issue of the
Contract.

FIXED ACCOUNT: an account that is part of JHVLICO's general account in which all
or a part of the Accumulated Value may be held for accumulation at fixed rates
of interest (not less than 3%) declared by JHVLICO periodically at its
discretion.
   
OWNER: the person(s) or entity, usually the person(s) or entity to whom the
Contract is issued, who has the sole right to exercise all rights and privileges
under the Contract except as otherwise provided in the Contract.    

DATE OF MATURITY OF A CONTRACT: the date elected by the Owner (or, if no
election is made, Annuitant's 85th birthday) as of which annuity payments will
commence. The election is subject to certain conditions described in "The
Annuity Period".

MINIMUM DEATH BENEFIT: the undertaking of JHVLICO under a Contract to make a
payment on the death of the Annuitant at any time before the date of maturity
equal to the greater of (a) the Accumulated Value of the Contract next
determined following JHVLICO's receipt of due proof of death, and (b) the    

6    
<PAGE>
 
aggregate amount of the purchase payments made under the Contract (reduced to
reflect partial withdrawals). See "The Accumulation Period--Death Benefit Before
Date of Maturity".

NET PURCHASE PAYMENT: the amount of any purchase payment reduced by applicable
taxes, if any, based on the amount of the purchase payment.
   
SERVICE CENTER: P.O. Box 9116, Boston, MA 02205-8654; telephone 800-741-8184.
    

SURRENDER VALUE: a cash payment made prior to a Contract's maturity, equal to
all or part of the Accumulation Shares credited to the Contract, less any
contract fee.
   
                             SUMMARY INFORMATION    

  The Contracts are designed both for purchase by individuals doing their own
retirement planning, including plans and trusts that do not qualify for special
tax treatment under the Internal Revenue Code of 1986, as amended ("Code") and
for purchase for persons participating in individual retirement annuity plans
satisfying the requirements of Section 408 of the Code.

THE CONTRACTS

  The Contracts offered are deferred annuity Contracts under which purchase
payments may be made in a lump sum or at intervals until the date of maturity of
the Contract, at which time annuity payments by JHVLICO will begin, if so
elected by the Owner.    
  An application for a Contract is available by calling 800-677-5700. Upon
completion, it is transmitted along with the purchase payment to JHVLICO's
Service Center for review. See "Purchase of Contracts."    

  JHVLICO also issues variable life insurance policies. These policies are
offered by means of other prospectuses, but use the same underlying Fund.

JOHN HANCOCK VARIABLE ANNUITY ACCOUNT I
   
  The Account is a separate investment account of JHVLICO, operated as a unit
investment trust, which supports benefits payable under its Contracts. There are
currently twenty-three subaccounts within the Account: Managed, Growth & Income,

PRINCIPAL UNDERWRITER OF THE ACCOUNT

  John Hancock Distributors, Inc., a wholly-owned subsidiary of John Hancock and
a registered broker-dealer since 1968, makes Contracts available through its
registered representatives licensed to sell life insurance policies and annuity
contracts.

PURCHASE PAYMENTS

  Purchase payments received under Contracts, after deduction of premium or
similar taxes, if applicable, are allocated by JHVLICO to one or more of the
variable subaccounts and the Fixed Account, as directed by the Owner.
   
  Purchase payments should be mailed to JHVLICO, P.O. Box 787, Boston, MA
02117-9910.    

  The initial purchase payment under a Contract must be at least $5,000 ($2,000
for individual retirement accounts) or $1,000 if made pursuant to an Annuity
Direct Deposit program; thereafter any payment must be at least $50.

  The maximum amount that can be deposited into a Contract per Contract Year is
$500,000. The maximum amount that can be deposited into any one subaccount per
Contract Year is $500,000 less any amount previously transferred to such
subaccount in such Contract Year. The maximum amount that can be deposited into
the Fixed Account per Contract Year (exclusive of the initial deposit) is
$100,000 less any amount previously transferred to the Fixed Account in such
Contract Year. The initial deposit into the Fixed Account can be as large as
$500,000. Deposits in or    

                                                                           7    
<PAGE>
 
transfers to the Fixed Account can only be made during the first 10 Contract
Years. No new deposits may be made after Annuitant's 85th birthday. These limits
may be waived by JHVLICO.

  There are also limitations on amounts transferred into the subaccounts and the
Fixed Account. See "Transfers Among Subaccounts" and "Appendix--The Fixed
Account and Fixed Account Value," respectively.

CHARGES AND DEDUCTIONS

  JHVLICO does not make any deductions for sales load from purchase payments.
Certain charges will be deducted from a Contract as described below.

MORTALITY AND EXPENSE RISK CHARGES

  JHVLICO makes a daily charge to the Account for mortality and expense risks
equal to 0.75% per annum of the average daily net assets of the Account (0.45%
on an annual basis for mortality risks and 0.30% on an annual basis for expense
risks). See "Charges for Mortality and Expense Risks."

ADMINISTRATIVE SERVICES CHARGE

  JHVLICO makes a daily charge to the Account for administrative services equal
to 0.25% per annum of the daily net assets of the Account. During the
Accumulation Period, JHVLICO also assesses an annual Contract fee of $30 on
Contracts having an Accumulated Value of less than $10,000. JHVLICO reserves the
right to increase the Contract fee up to $50, subject to state regulations. See
"Charges for Administrative Services."

PREMIUM TAX CHARGE

  Deductions are made on any applicable taxes based on the amount of purchase
payment; currently such state taxes range from 0% to 5% of each purchase
payment. See "Premium or Similar Taxes."

FUND EXPENSES

  Investment management fees at annual rates ranging from 0.20% to 1.00% of
average daily net assets are paid by the Portfolios to John Hancock. The
Portfolios also incur charges for other expenses incurred in their operations.
Investment management fees and other expenses are reflected in the net asset
value of each Portfolio's shares. For a description of these charges and
expenses, see the prospectus for the Series Trust.

WITHDRAWAL PRIOR TO MATURITY

  At any time before annuity payments begin, if the Annuitant is living, a
Contract may be surrendered in full for its Surrender Value or a portion of the
value of the Contract may be withdrawn, subject to certain limits. See
"Surrender of Contract; Partial Withdrawals." A 10% penalty tax may be
applicable to the taxable portion (earnings) withdrawn before the Owner attains
age59 1/2.

SYSTEMATIC WITHDRAWALS

  The Owner may pre-authorize a periodic withdrawal plan. Payments may be
monthly, quarterly, semi-annual, or annual, and may be for a level dollar
amount. A minimum Accumulated Value of $25,000 is required to start the program.
See "Systematic Withdrawals."

DOLLAR-COST AVERAGING

  The Owner may elect to have amounts transferred automatically from any
variable subaccount into one or more of the other variable subaccounts.
Transfers may be made monthly, quarterly, semi-annually, or annually for a
minimum of $250. A minimum Accumulated Value of $20,000 is required to start the
program. See "Dollar-Cost Averaging."

GUARANTEED MINIMUM DEATH BENEFIT

  Contracts include a death benefit payable on the death of the Annuitant prior
to annuitization that is the greater of (a) the Accumulated Value of the
Contract, and (b) the purchase payments made under the Contract, adjusted for
any prior partial withdrawals. See "Death Benefit Before Date of Maturity."

FREE-LOOK PROVISION
   
  An Owner may surrender the Contract for any reason during the "free-look
period" and receive the following in cash: (1) the gross payments made if the
Contract is an individual retirement annuity or the Contract is issued in
Hawaii, Idaho, Missouri, Nebraska, North Carolina, Oklahoma, Oregon, South
Carolina, Washington, West Virginia, Wisconsin, or Utah, or (2) the Accumulated
Value of the Contract plus any deductions previously made from purchase payments
for premium or similar taxes if the Contract is issued in any other state and is
not an individual retirement annuity. In most cases, the "free-look period" is
10 days after the Contract's receipt, but there are exceptions. If the Contract
is issued in Idaho or North Dakota, the free-look period is 20 days. If the
Contract is issued in North Carolina, South Carolina, or Wisconsin, the
free-look period is 31 days. Finally, if the Contract is issued in California to
an Owner 60 years of age or older, the Owner may surrender the Contract within
30 days after its receipt, and, in that event, the gross purchase payments made
will be refunded to the Owner.    

                              THE VARIABLE ANNUITY

  A variable annuity is significantly different from a fixed annuity in that it
is the Owner and Annuitant under a variable annuity who assume the risk of
investment gain or loss rather than the insurance company. While under a fixed
annuity the insurance company guarantees a specified interest rate for a period
of time and specified monthly annuity payments, the amounts of annuity payments
under a variable annuity are not    

8    
<PAGE>
 
guaranteed and will vary with the investment performance of the portfolio
securities in the underlying Fund.

  Based upon the Owner's investment objective, the Owner directs the allocation
of purchase payments and Accumulated Values among the subaccounts on a
continuing basis. There can be no assurance that these investment objectives
will be achieved.

             JHVLICO, JOHN HANCOCK, THE ACCOUNT AND THE SERIES FUND

JHVLICO AND JOHN HANCOCK

  JHVLICO, a stock life insurance company chartered in 1979 under Massachusetts
law, is authorized to transact a life insurance and annuity business in
Massachusetts and all other states, except New York. JHVLICO began selling
variable life insurance policies in 1980.

  JHVLICO is a wholly-owned subsidiary of John Hancock, a mutual life insurance
company chartered in Massachusetts in 1862. Its Home Office is at 200 Clarendon
Street, Boston, Massachusetts 02117. It conducts a conventional life insurance
business in all of the United States, the District of Columbia and Puerto Rico.
John Hancock sells insurance policies and annuity contracts directly to
customers or through a career agency system, banks, or broker/dealers. It is
anticipated that John Hancock will from time to time make additional capital
contributions to JHVLICO to enable it to meet its reserve requirements and
expenses in connection with its business and John Hancock is committed to make
additional capital contributions if necessary to ensure that JHVLICO maintains a
positive net worth.

THE ACCOUNT

  The Account is a separate account established under Massachusetts law on June
15, 1994. The Account, although an integral part of JHVLICO, meets the
definition of a "separate account" under the Federal securities laws and is
registered as a unit investment trust under the Investment Company Act of 1940,
as amended ("1940 Act").

  The Account's assets are the property of JHVLICO and the obligations under the
Contracts are the obligations of JHVLICO. Each Contract provides that the
portion of the Account's assets equal to the reserves and other liabilities
under the Contract with respect to the Account shall not be chargeable with
liabilities arising out of any other business JHVLICO may conduct. In addition
to the net assets and other liabilities for Contracts, the Account's assets
include assets derived from charges made by JHVLICO and, possibly, funds
contributed by JHVLICO to commence operation of the subaccounts or their
predecessors. From time to time these additional assets may be transferred in
cash by JHVLICO to its general account. Before making any such transfer, JHVLICO
will consider any possible adverse impact the transfer might have on any
subaccount.

  Income, gains and losses, whether or not realized, from assets allocated to
the Account are, in accordance with the Contracts, credited to or charged
against the Account without regard to other income, gains or losses of JHVLICO.
   
  There currently are twenty-three subaccounts in the Account: Managed, Growth &
Income, Equity Index, Large Cap Value, Large Cap Growth, Mid Cap Value, Mid Cap
Growth, Diversified Mid Cap Growth, Real Estate Equity, Small/Mid Cap CORE,
Small Cap Value, Small Cap Growth, Global Equity, International Balanced,
International Equity Index, International Opportunities, Emerging Markets
Equity, Short-Term Bond, Bond Index, Sovereign Bond, Strategic Bond, High Yield
Bond, and Money Market. The assets in each are invested in a separate class of
shares issued by the Fund, but the assets of one subaccount are not necessarily
legally insulated from liabilities associated with another subaccount. New
subaccounts may be added and made available to Owners.    

THE SERIES FUND

  The Fund is a "series" type of mutual fund which is registered under the 1940
Act as an open-end diversified management investment company and organized as a
Massachusetts business trust. The Fund serves as the investment medium for the
Account and other unit investment trust separate accounts established by John
Hancock and by JHVLICO for variable life insurance policies and variable annuity
contracts. A full description of the Fund, its investment objectives, policies
and restrictions, its charges and expenses, and all other aspects of its
operation is contained in the attached prospectus (which should be read
carefully before investing) and the statement of additional information referred
to therein, which should be read together with this prospectus. Among other
items, note the description of the need to monitor events on the part of the
Fund's Board of Trustees for possible conflicts between separate accounts and
other consequences.

  The following is a brief summary of the investment objectives of each
Portfolio.

  JHVLICO will purchase and redeem Fund shares for the Account at their net
asset value without any sales or redemption charges. Shares of the Fund
represent an interest in one of the Portfolios of the Fund which corresponds to
the subaccount of the Account. Any dividend or capital gains distributions
received by the Account will be reinvested in Fund shares at their net asset
value as of the dates paid. Any such distribution will result in a reduction in
the value of the Fund shares of the Portfolio from which the distribution was
made. The total net asset value of the Account will not change because of such
distribution, however.

  On each Valuation Date, shares of each Portfolio are purchased or redeemed by
JHVLICO for each subaccount based on, among other things, the amount of net
purchase payments allocated to the subaccount, dividends and distributions
reinvested, transfers to, from and among subaccounts, all to be effected as of
that date. Such purchases and redemptions are effected at the net asset value
per Fund share for each Portfolio determined on that same Valuation Date.

                    CHARGES UNDER VARIABLE ANNUITY CONTRACTS

CHARGES FOR MORTALITY AND EXPENSE RISKS

  While the variable annuity payments to Annuitants will vary in accordance with
the investment performance of the Account, the amount of such payments will not
be decreased because of adverse mortality experience of Annuitants as a class or
because of an increase in actual expenses of JHVLICO over the expense charges
provided for in the Contracts. JHVLICO assumes the risk that Annuitants as a
class may live longer than expected    

                                                                          11    
<PAGE>
 
(necessitating a greater number of annuity payments) and that its expenses may
be higher than the deductions for such expenses. JHVLICO also provides a minimum
death benefit upon the death of the Annuitant.

  In return for the assumption of these mortality and expense risks, JHVLICO
charges the Account daily 0.001233% (0.45% on an annual basis) of the current
value of Account net assets for mortality risks and 0.000822% (0.30% on an
annual basis) for expense risks. JHVLICO reserves the right to revise the
proportionate amounts of the charge as between mortality risks and expense
risks, should estimates change. Nevertheless, the aggregate charge will not
exceed 0.75% on an annual basis.

CHARGES FOR ADMINISTRATIVE SERVICES

  JHVLICO maintains an account for each Owner and Annuitant and makes all
disbursements of benefits. JHVLICO also furnishes such administrative and
clerical services, including the calculation of Accumulation Share values and
the values and interests determined thereby, as are required for each
subaccount. JHVLICO makes disbursements from Account funds to pay obligations
chargeable to the Account and maintains the accounts, records, and other
documents relating to the business of the Account required by regulatory
authorities.

  For these and other administrative services, JHVLICO makes a daily charge to
the Account of 0.000685% (0.25% on an annual basis) of the current value of its
net assets and assesses, during the Accumulation Period, a contract fee of $30
on Contracts having an Accumulated Value of less than $10,000. The contract fee
will be deducted at the beginning of each Contract Year after the first and at a
full surrender during a Contract Year. JHVLICO reserves the right to increase
this fee up to a maximum of $50 subject to state regulations. The contract fee
will be deducted from each subaccount and the Fixed Account in the same
proportion that the Accumulated Value of the Contract in that subaccount or
Fixed Account bears to the full Accumulated Value of the Contract. However, the
portion of the contract fee allocated to the Fixed Account will not be deducted
from the Fixed Account to the extent it would result in an accumulation of
purchase payments or other amounts allocated to the Fixed Account at less than
the guaranteed minimum rate of 3 percent. In such cases, the unpaid portion of
the contract fee allocable to the Fixed Account will be deducted proportionally
from the subaccounts, if any.     VARIATIONS IN CHARGES    

  In the future, JHVLICO may allow a reduction in or the elimination of the
charges for mortality and expense risks, the administrative services charge, or
the annual contract fee assessed on Contracts sold to groups or classes of
individuals in a manner resulting in a reduction in the expenses associated with
the sale of such Contracts or the costs associated with administering or
maintaining such Contracts.

  The entitlement to such a reduction in or elimination of charges and fees will
be determined by JHVLICO based upon factors such as the following: (1) the size
of the initial purchase payment, (2) the size of the group or class, (3) the
total amount of purchase payments expected to be received from the group or
class and the manner in which purchase payments are remitted, (4) the nature of
the group or class for which the Contracts are being purchased and the
persistency expected from that group or class as well as the mortality risks
associated with that group or class, or (5) the purpose for which the Contracts
are being purchased and whether that purpose makes it likely that costs and
expenses will be reduced.

  JHVLICO will make any reduction in charges or fees according to its own rules
in effect at the time an application for a Contract is approved. JHVLICO
reserves the right to change these rules from time to time. Any variation in
charges or fees will reflect differences in costs and services, will apply
uniformly to all prospective Contract purchasers in the group or class, and will
not be unfairly discriminatory to the interests of any Owner.

PREMIUM OR SIMILAR TAXES

  Several states and local governments impose a premium or similar tax on
annuities. Currently, such taxes range from 0% to 5% of the Accumulated Value
applied to an Annuity Option. Ordinarily, any state-imposed premium or similar
tax will be deducted from the Accumulated Value of the Contract only at the time
of annuitization.

  For Contracts issued in South Dakota and Kentucky, however, JHVLICO pays a tax
on each premium payment at the time it is made. JHVLICO will deduct a charge for
these taxes from the Accumulated Value of the Contract at the time of
annuitization, death, surrender, or withdrawal. Such a charge is equal to the
applicable premium tax percentage stated above times the amount of Accumulated
Value that is applied to an Annuity Option, surrendered, withdrawn, or at death.
The net economic effect of this procedure is not significantly different than if
JHVLICO deducted the premium tax from each premium payment when received.
   
  The charges described above (exclusive of taxes) and the Contracts' annuity
purchase rates will apply for the duration of each Contract and, except as noted
above, will not be increased by JHVLICO. However, these charges do not include
all of the expenses which may be incurred for the account of Owners and
Annuitants. Additional charges may be made directly to the Account for taxes, if
any, based on the income of, capital gains of, assets in, or the existence of,
the Account and interest on funds borrowed. In addition, JHVLICO reserves the
right to deduct premium taxes from premiums when paid. Moreover, the Account
purchases and redeems shares of the Fund at net asset value, a value which
reflects the deduction from the assets of the Fund of its investment management
fee and of certain operating expenses described briefly under "Summary
Information."

<PAGE>
 
                                  THE CONTRACTS

  The descriptions herein are based on certain provisions of the Contracts
offered by this Prospectus. Reference should be made to the actual Contracts and
to the terms and limitations of any tax qualified plan which is to be funded by
such Contracts. Tax qualified plans are subject to several requirements and
limitations which may affect the terms of any particular Contract or the
advisability of taking certain action permitted thereby.

PURCHASE OF CONTRACTS

  Any person wishing to purchase a Contract may submit an application and an
initial purchase payment to JHVLICO, as well as any other form or information
that JHVLICO may require. If the application is complete and the Contract
applied for is suitable, the Contract will be issued and thereafter delivered
directly to the Owner. If the completed application is received in proper order,
the initial purchase payment accompanying the completed application is applied
within two business days after receipt. If an initial purchase payment is not
applied within five business days after receipt, it will be refunded unless
JHVLICO has received the consent of the applicant to retain the purchase payment
until receipt of information necessary to complete the issuance of the Contract.

  The initial purchase payment must be at least $5,000 ($2,000 for individual
retirement accounts) or $1,000 if made pursuant to an annuity direct deposit
program and subsequent payments must be at least $50 in amount, except where
otherwise permitted by JHVLICO. Maximum payments to any one subaccount in a
single Contract Year are $500,000 less any amount previously transferred into
such subaccount in such year. Maximum payments to the Fixed Account in a single
Contract Year, exclusive of the initial premium, is $100,000 less any amount
previously transferred into the Fixed Account in such year. Increases in
purchase payments beyond the foregoing limits may be made only with JHVLICO's
written consent. While the Annuitant is living and the Contract is in force,
purchase payments may be made at any time before maturity, except that no new
purchase payments may be made after the Annuitant's 85th birthday. These limits
may be waived by JHVLICO.

ANNUITY DIRECT DEPOSIT PROGRAM

  The Annuity Direct Deposit ("ADD") Program is a program pursuant to which
purchase payments are automatically paid from the Owner's checking account on a
specified day each month. The minimum monthly payment for the ADD program is
$50. The Owner has the right to change the monthly payment amount or discontinue
the service at any time by telephoning JHVLICO at 800-741-8184.

                             THE ACCUMULATION PERIOD

ALLOCATION OF PURCHASE PAYMENTS (ACCUMULATION SHARES)

  Net purchase payments are allocated by JHVLICO to any one or more of the
subaccounts or the Fixed Account or allocated among the subaccounts and the
Fixed Account in the proportion specified in the application for the Contract or
as directed by the Owner from time to time. Any change in the election will be
effective as to purchase payments made after the receipt by JHVLICO at its
Service Center of notice in form satisfactory to JHVLICO.

  Each net purchase payment allocated to a subaccount purchases Accumulation
Shares of that subaccount at the value of such shares next determined after the
receipt of such net purchase payment at the Service Center of JHVLICO. See
"Variable Account Valuation Procedures." The number of Accumulation Shares of a
subaccount purchased with a specific purchase payment will be determined by
dividing the net purchase payment by the value of an Accumulation Share in that
subaccount when the net purchase payment is applied. The value of the
Accumulation Shares so purchased will vary in amount thereafter, depending upon
the investment performance of the subaccount and the charges and deductions made
against the subaccount.

VALUE OF ACCUMULATION SHARES

  At any date prior to a Contract's maturity date, the total value of the
Accumulation Shares in a subaccount which have been credited to a Contract can
be computed by multiplying the number of such Accumulation Shares by the
appropriate Accumulation Share Value in effect for such date.
   
TRANSFERS TO AND FROM SUBACCOUNTS    

  Not more often than twelve times in each Contract Year, without JHVLICO's
prior approval, and not on or within 30 days prior to the date of maturity, the
Owner may elect to transfer all or any part of the Accumulation Shares or
Annuity Units credited to a Contract from one subaccount to another. Maximum
transfers into any one subaccount in a single Contract Year is $500,000 less
premiums previously deposited into such subaccount in such Contract Year. Any
such transfer will result in the redemption and purchase of Accumulation Shares
or Annuity Units, whichever is applicable, on the basis of the respective values
next determined after receipt of notice satisfactory to JHVLICO at its Service
Center. (For Fixed Account transfers, see "Appendix--Fixed Account and Fixed
Account Value.") A transfer pursuant to the dollar-cost averaging feature
discussed below counts toward the twelve transfers per year.
   
  An Owner may request a transfer in writing or, once a written telephone
transfer authorization form is completed by the Owner, the Owner may request a
transfer by telephoning JHVLICO at 800-741-8184 or sending a written request via
the        

                                                                          13    
<PAGE>
 
JHVLICO fax machine at 888-553-4732. Any written request should include the
Owner's name, daytime telephone number, and Contract number as well as the names
of the subaccounts from which and to which money will be transferred. JHVLICO
reserves the right to modify, suspend, or terminate telephone transfers at any
time without notice to the Owners. If the fax request option becomes
unavailable, another means of telecommunication will be substituted.

  An Owner who authorizes telephone transfers will be liable for any loss,
expense or cost arising out of any unauthorized or fraudulent telephone transfer
instructions which JHVLICO reasonably believes to be genuine, unless such loss,
expense or cost is the result of JHVLICO's mistake or negligence. JHVLICO
employs procedures which provide safeguards against the execution of
unauthorized transfers, and which are reasonably designed to confirm that
transfer instructions received by telephone are genuine. These procedures
include requiring personal identification, tape recording calls, and providing
written confirmation to the Owner. If JHVLICO does not employ reasonable
procedures to confirm that instructions communicated by telephone are genuine,
it may be liable for any loss due to unauthorized or fraudulent instructions.

DOLLAR-COST AVERAGING
   
  The Owner may elect to have automatically transferred on a monthly, quarterly,
semi-annual or annual basis, at no cost, part of the Accumulation Shares
credited to any variable subaccount into one or more of the other variable
subaccounts. The minimum amount of each transfer is $250. Automatic transfers
into the Fixed Account are not permitted. To begin the program, the Accumulated
Value of the Contract must be at least $20,000. The program continues until the
earlier of 12, 24, or 36 (as chosen by the Owner) months or full liquidation of
the variable subaccount from which the monies are being transferred. Transfers
may be made via telephone or facsimile machine provided a telephone
authorization form has been completed by the Owner. JHVLICO reserves the right
to terminate the Dollar-Cost Averaging program at any time.    

SURRENDER OF CONTRACT; PARTIAL WITHDRAWALS
   
  Prior to its date of maturity, if the Annuitant is living, a Contract may be
surrendered for a cash payment representing all or part of the total Accumulated
Value of the Contract. The appropriate number of Accumulation Shares will be
redeemed at their value next determined after the receipt by JHVLICO at its
Service Center of notice in form satisfactory to JHVLICO. Unless directed
otherwise by the Owner, that portion of the Accumulated Value of the Contract
redeemed in a partial withdrawal will be redeemed in each subaccount and in the
Fixed Account in the same proportion as the Accumulated Value of the Contract is
then allocated among the subaccounts and the Fixed Account. The redemption value
may be more or less than the net purchase payments applied under the Contract to
purchase the Accumulation Shares, depending upon the market value of the Fund
shares held in the subaccount at the time. The cash payment the Owner will
receive will be equal to the Accumulated Value minus any unpaid contract fees.
The resulting cash payment will be made in a single sum, ordinarily within seven
days after receipt of such notice. As described under "Miscellaneous
Provisions--Deferment of Payment," however, redemption and payment may be
delayed under certain circumstances. See "Federal Income Taxes" for possible
adverse tax consequences of certain surrenders and partial withdrawals.    

  Any request for a surrender or partial withdrawal should be mailed to the
Service Center, P.O. Box 9116, Boston, MA 02205-8654.

  A partial withdrawal is not permitted in an amount less than $100 or if the
total Accumulated Value of a Contract remaining after the withdrawal would be
less than $1,000. A partial withdrawal is not a loan and, once made, cannot be
repaid.

  In the event the Accumulated Value of the Contract becomes zero, the Contract
will terminate.

SYSTEMATIC WITHDRAWAL

  The Owner may elect to participate in a systematic withdrawal plan, which
enables the Owner to pre-authorize a periodic exercise of the contractual
withdrawal rights described above. Owners entering into such a plan instruct
JHVLICO to withdraw a level dollar amount from the Contract on a monthly,
quarterly, semi-annual, or annual basis. The amount deducted will result in the
cancellation of Accumulation Shares from each applicable subaccount in the ratio
that the value of each subaccount bears to the total Accumulated Value.
Currently, systematic withdrawal is available to Owners who have a Contract
Value of $25,000 or more. The Company reserves the right to modify the
eligibility rules or other terms and conditions of this program at any time,
without notice. The minimum withdrawal is $100. The systematic withdrawal will
terminate upon cancellation by the Owner or in the event that the Accumulated
Value of the Contract becomes $5,000 or less. Systematic withdrawal is not
available to Contracts participating in the Dollar-Cost Averaging program. There
may be tax consequences associated with the systematic withdrawal plan. (See
"Federal Income Taxes.")

DEATH BENEFIT BEFORE DATE OF MATURITY

  If the Annuitant dies before the date of maturity or the surrender or
termination of a Contract, a death benefit is payable. The death benefit will be
the greater of (a) the Accumulated Value of the Contract next determined
following receipt at the Service Center of JHVLICO of due proof of death,
together with any required instructions as to method of settlement and (b) the
amount of the purchase payments made under the Contract reduced by all prior
partial withdrawals.

  Payment of the death benefit will be made in a single sum to the beneficiary
designated by the Owner prior to the Annuitant's death unless an optional method
of settlement has been elected by the Owner. If an optional method of settlement
has not been elected by the Owner, the beneficiary may elect an optional    

14    
<PAGE>
 
method of settlement in lieu of a single sum. No deduction is made for sales or
other expenses upon such election. Payment will be made in a single sum in any
event if the death benefit is less than $5,000. See "Annuity Period--Annuity
Options." If there is no surviving beneficiary, the Owner, or his or her estate
is the beneficiary.

  The Code requires certain distribution provisions to be included in any
Contract used to fund other than a tax qualified plan (See "Federal Income
Taxes"). Failure to include the required distribution provisions results in the
Contract not being treated as an annuity for Federal tax purposes. The Code
imposes comparable distribution requirements for Contracts used to fund tax
qualified plans. These required provisions for tax qualified plans will be
reflected by means of separate disclosures and endorsements furnished by JHVLICO
to Owners.

  The Code distribution requirements are expected to present no practical
problems when the Annuitant and Owner are the same person. Nevertheless, all
Owners of Contracts not used to fund a tax qualified plan and IRA Contract
Owners should be aware that the following distribution requirements are
applicable notwithstanding any provision to the contrary in the Contract (or in
this prospectus) relating to payment of the death benefit or death of the
Annuitant.

  If the Owner dies on or after annuity payments have begun, any remaining
benefit must be paid out at least as rapidly as under the method of making
annuity payments then in effect. If the Owner dies before annuity payments have
begun: (a) if the beneficiary is the surviving spouse of the Owner, the
beneficiary may continue the Contract in force as Owner; or (b) if the
beneficiary is not the surviving spouse of the Owner, or if the beneficiary is
the surviving spouse of the Owner but does not choose to continue the Contract,
the entire interest in the Contract on the date of death of the Owner must be:
(i) paid out in full within 5 years of the Owner's death, or (ii) applied in
full towards the purchase of a life annuity on the beneficiary with payments
commencing within 1 year of the Owner's death.

  The Code imposes comparable distribution requirements on tax qualified plans.

  If the Owner is not the Annuitant, "the entire interest in the Contract on the
date of death of the Owner" is equal to the Surrender Value if paid out in full
within five years of the Owner's death, or is equal to the Accumulated Value if
applied in full towards the purchase of a life annuity on the beneficiary with
payments commencing within one year of the Owner's death.

  Note that "the entire interest in the Contract on the date of death of the
Owner" which is payable if the Owner dies before annuity payments have begun may
be an amount less than the death benefit which would have been payable if the
Annuitant had died instead. Note also that notice should be furnished promptly
to JHVLICO upon the death of the Owner.

                               THE ANNUITY PERIOD

  During the annuity period, the total value of any one Contract must be
allocated among no more than four "accounts" (i.e., the subaccounts and/or the
Fixed Account). Amounts allocated to the Fixed Account will provide annuity
payments on a fixed basis; amounts allocated to the subaccounts will provide
annuity payments on a variable basis. If more than four accounts are being used
on the maturity date, JHVLICO will divide the total Accumulated Value of the
Contract proportionately among the four accounts with the largest Accumulated
Values. Only variable annuity payments are described in this prospectus.

  Annuity payments will commence on the date of maturity of the Contract if the
Annuitant is then living and the Contract is then in force. Each Contract will
provide at the time of its issuance for a Life Annuity with Ten Years Certain.
Under this form of annuity, variable annuity payments are made monthly to the
Annuitant for life and, if the Annuitant dies within ten years after the date of
maturity of the Contract, the payments remaining in the ten-year period will be
made to the contingent payee, subject to the terms of any supplementary
agreement issued. (NOTE: The terminology used in a supplementary agreement may
differ from that used in a Contract. For example, in a supplementary agreement,
the term "payee" may be used to refer to the Annuitant or to some other person
named by the Annuitant or the Owner to receive payments under the supplementary
agreement in the event of the Annuitant's death, and the term "contingent payee"
may be used to refer to the beneficiary.) A different form of annuity may be
elected by the Owner, as described in "Annuity Options," prior to the date of
maturity of the Contract. Once a given form of annuity takes effect, it may not
be changed.

  If the initial monthly annuity payment under a Contract would be less than
$50, JHVLICO may make a single sum payment equal to the total Surrender Value of
the Contract on the date the initial payment would be payable, in place of all
other benefits, or, if agreed to by the Owner, make periodic payments at
quarterly, semi-annual or annual intervals in place of monthly payments.

  Each Contract specifies the date of maturity at the time of its issuance as
the Annuitant's 85th birthday. The Owner may subsequently elect a different date
of maturity, however. Unless otherwise permitted by JHVLICO, such subsequently
elected date may be no earlier than twelve months after the date the first
payment is applied to the Contract, nor later than the Annuitant's 85th
birthday. The election is made by written notice received by JHVLICO at its
Service Center before the provisional date of maturity and at least 31 days
prior to the date of maturity. Particular care should be taken in electing the
date of maturity of Contracts issued under individual retirement annuity
contract plans. (See "Federal Income Taxes.")

VARIABLE MONTHLY ANNUITY PAYMENTS

  Variable monthly annuity payments under a Contract are determined by
converting each subaccount's Accumulation    

                                                                          15    
<PAGE>
 
Shares credited to the Contract (less any applicable premium tax) into the
respective Annuity Units of each subaccount on the date of maturity of the
Contract or some other date elected for commencement of variable annuity
payments. See "Calculation of Annuity Units."

  The amount of each annuity payment after the first payment will depend on the
investment performance of the subaccounts being used. If the actual net
investment return (after deducting all charges) of a subaccount during the
period between the dates for determining two monthly payments based on that
subaccount exceeds the "assumed investment rate" (explained below), the latter
monthly payment will be larger than the former. On the other hand, if the actual
net investment return is less than the assumed investment rate, the latter
monthly payment will be smaller than the former.

ASSUMED INVESTMENT RATE

  The assumed investment rate for all Contracts will be3 1/2% per year except as
provided below. The assumed investment rate is significant in determining the
amount of the initial variable monthly annuity payment and the amount by which
subsequent variable monthly payments are more or less than the initial variable
monthly payment.

  Where applicable state law so provides, an Owner may elect a variable annuity
option with a different assumed investment rate, not in excess of 6%, if such a
rate is made available by JHVLICO in the Owner's state. Election of a higher
assumed investment rate produces a larger initial annuity payment but also means
that eventually the monthly annuity payments would be smaller than if a lower
assumed investment rate had been elected.

CALCULATION OF ANNUITY UNITS

  Accumulation Shares are converted into Annuity Units by first multiplying the
number of each subaccount's Accumulation Shares credited to the Contract on the
date of conversion by the appropriate Accumulation Share Value as of ten
calendar days prior to the date the initial variable monthly annuity payment is
due. For each subaccount the resulting value (less any applicable premium tax)
is then multiplied by the applicable annuity purchase rate, which reflects the
age and possibly sex of the Annuitant and the assumed investment rate, specified
in the Contract. This computation determines the amount of each subaccount's
initial monthly variable annuity payment to the Annuitant. The number of each
subaccount's Annuity Units to be credited to the Contract is then determined by
dividing the amount of each subaccount's initial variable monthly annuity
payment by each subaccount's Annuity Unit Value as of ten calendar days prior to
the date the initial payment is due.

ANNUITY OPTIONS

  The Owner may elect an Annuity Option during the lifetime of the Annuitant by
written notice received by JHVLICO at its Service Center prior to the date of
maturity of the Contract. If no option is selected, Option A with Ten Years
Certain will be used. A beneficiary entitled to payment of a death benefit in a
single sum may, if no election has been made by the Owner prior to the
Annuitant's death, elect an Annuity Option by written notice received by JHVLICO
at its Service Center prior to the date the proceeds become payable. The Owner
may also elect that the Surrender Value be applied to an Annuity Option at the
time of a full surrender of a Contract that has been outstanding for at least 6
months. No option may be elected if the Accumulated Value of the Contract to be
applied is less than $5,000 or the amount of the first monthly payment would be
less than $50. Among the options available are the following two basic Annuity
Options.

OPTION A: LIFE ANNUITY WITH FIVE, TEN OR TWENTY YEARS CERTAIN

  Variable monthly payments will be made for a designated period of 5, 10 or 20
years and thereafter as long as the payee lives, with the guarantee that if the
payee dies prior to the end of the 5, 10 or 20 year period, whichever is
applicable, payments will continue for the remainder of the guaranteed period to
a contingent payee, subject to the terms of any supplementary agreement issued.

OPTION B: LIFE ANNUITY WITHOUT REFUND

  Variable monthly payments will be made to the payee as long as he lives. No
minimum number of payments is guaranteed.

OTHER CONDITIONS

  JHVLICO reserves the right at its sole discretion to make available to Owners
and other payees optional methods of payment in addition to the Annuity Options
described in this Prospectus and the applicable Contract.

  Federal income tax requirements currently applicable to individual retirement
annuity plans provide that the period of years guaranteed under Option A cannot
be any greater than the joint life expectancies of the payee and his or her
designated beneficiary.

  If the Owner dies on or after annuity payments have begun, any remaining
benefit must be paid out at least as rapidly as under the method of making
annuity payments then in effect.

                      VARIABLE ACCOUNT VALUATION PROCEDURES

VALUATION DATE--A Valuation Date is any date on which the New York Stock
Exchange is open for trading and on which the Fund values its shares. On any
date other than a Valuation Date, the Accumulation Share Value or Annuity Unit
Value will be the same as that on the next following Valuation Date.

VALUATION PERIOD--A Valuation Period is that period of time from the beginning
of the day following a Valuation Date to the end of the next following Valuation
Date.
   

16    
<PAGE>
 
ACCUMULATION SHARE VALUE--The Accumulation Share Value is calculated separately
for each subaccount. The value of one Accumulation Share on any Valuation Date
is determined for each subaccount by multiplying the immediately preceding
Accumulation Share Value by the applicable Net Investment Factor for the
Valuation Period ending on such Valuation Date.

ANNUITY UNIT VALUE--The Annuity Unit Value is calculated separately for each
subaccount. The value of one Annuity Unit on any Valuation Date is determined
for each subaccount by first multiplying the immediately preceding Annuity Unit
Value by the applicable Net Investment Factor for the Valuation Period ending on
such date and then multiplying this product by an adjustment factor which will
neutralize the assumed investment rate used in determining the amounts of
annuity payable. The adjustment factor for a Valuation Period of one day for
Contracts with an assumed investment rate of3 1/2% per year is .99990575. The
assumed investment rate is neutralized by applying the adjustment factor so that
the variable annuity payments will increase only if the actual net investment
rate of the subaccount exceeds3 1/2% per year and will decrease only if it is
less than3 1/2% per year.

NET INVESTMENT FACTOR--The Net Investment Factor for each subaccount for any
Valuation Period is equal to 1 plus the applicable net investment rate for such
Valuation Period. A Net Investment Factor may be more or less than 1. The net
investment rate for each subaccount for any Valuation Period is equal to (a) the
accrued investment income and capital gains and losses, whether realized or
unrealized, of the subaccount for such Valuation Period less (b) the sum of a
deduction for any applicable income taxes and, for each calendar day in the
Valuation Period, a deduction of 0.002740% of the value of each subaccount at
the beginning of the Valuation Period, the result then being divided by (c) the
value of the total net assets of each subaccount at the beginning of the
Valuation Period.

ADJUSTMENT OF UNITS AND VALUES--JHVLICO reserves the right to change the number
and value of the Accumulation Shares or Annuity Units or both credited to any
Contract, without the consent of the Owner or any other person, provided strict
equity is preserved and the change does not otherwise affect the benefits,
provisions or investment return of the Contract.

                            MISCELLANEOUS PROVISIONS

RESTRICTION ON ASSIGNMENT

  In order to qualify for favorable tax treatment, certain Contracts may not be
sold, assigned, discounted or pledged as collateral for a loan or as security
for the performance of an obligation or for any other purpose, to any person,
unless the Owner is the trustee of a trust described in Section 401(a) of the
Code. Because an assignment, pledge or other transfer may be a taxable event an
Owner should consult a competent tax adviser before taking any such action.

DEFERMENT OF PAYMENT

  Payment of the value of any Accumulation Shares in a single sum upon a
surrender or partial withdrawal will ordinarily be made within seven days after
receipt of the written request therefor by JHVLICO at its Service Center.
However, redemption may be suspended and payment may be postponed at times (a)
when the New York Stock Exchange is closed, other than customary weekend and
holiday closings, (b) when trading on that Exchange is restricted, (c) when an
emergency exists as a result of which disposal of securities in a subaccount is
not reasonably practicable or it is not reasonably practicable to determine the
value of the net assets of a subaccount or (d) when a governmental body having
jurisdiction over the Account by order permits such suspension. Rules and
regulations of the Securities and Exchange Commission, if any are applicable,
will govern as to whether conditions described in (b) or (c) exist.

RESERVATION OF RIGHTS

  JHVLICO reserves the right to add or delete subaccounts, to change the
underlying investments of any subaccount, to operate the Account in any form
permitted by law and to terminate the Account's registration under the 1940 Act
if such registration should no longer be legally required. Certain changes may,
under applicable laws and regulations, require notice to or approval of Owners.
Otherwise, changes do not require such notice or approval.

OWNER AND BENEFICIARY

  The Owner has the sole and absolute power to exercise all rights and
privileges under the Contract, except as otherwise provided by the Contract or
by written notice of the Owner. The Owner and the beneficiary are designated in
the application and may be changed by the Owner, effective upon receipt of
written notice at the Service Center, subject to the rights of any assignee of
record, any action taken prior to receipt of the notice and certain other
conditions. While the Annuitant is alive, the Owner may be changed by written
notice. The beneficiary may be changed by written notice no later than receipt
of due proof of the death of the Annuitant. The change will take effect whether
or not the Owner or the Annuitant is then alive.

                              FEDERAL INCOME TAXES

THE ACCOUNT AND JHVLICO

  JHVLICO is taxed as a life insurance company under the Code. The Account is
part of JHVLICO's total operations and is not taxed separately as a "regulated
investment company" or otherwise.

  The Contracts permit JHVLICO to charge against the Account any taxes, or
provisions for taxes, attributable to the operation or existence of the
Contracts or the Account. No specific charge is currently made against the
Account for any such taxes. JHVLICO pays such taxes out of its general account
assets which may consist of, among other things, proceeds    

                                                                          17    
<PAGE>
 
derived from mortality and expense risk charges deducted from the Account.
Currently, JHVLICO does not anticipate making a separate charge for income and
other taxes because of the level of such taxes. If the level of current tax is
increased, or is expected to increase in the future, JHVLICO reserves the right
to make such a charge in the future.

  JHVLICO assumes no responsibility for determining whether a particular
retirement plan satisfies the applicable requirements of the Code.

CONTRACTS PURCHASED OTHER THAN TO FUND A TAX QUALIFIED PLAN

 The Owner or Other Payee

  The Contracts are considered annuity contracts under Section 72 of the Code.
Currently no Federal income tax is payable on increases in Contract Value until
payments are made to the Owner or other payee under such Contract. However, a
Contract owned other than by a natural person is not generally an annuity for
tax purposes and any increase in value thereunder is taxable as ordinary income
as accrued.

  When payments under a Contract are made in the form of an annuity, the amount
of each payment is taxed to the Owner or other payee as ordinary income to the
extent that such payment exceeds an allocable portion of the Owner's "investment
in the contract" (as defined in the Code). In general, an Owner's "investment in
the contract" is the aggregate amount of purchase payments made by the Owner,
reduced by any amounts previously distributed from the Contract that were not
subject to tax. The portion of each variable annuity payment to be excluded from
income is determined by dividing the "investment in the contract," adjusted by
any refund feature, by the number of periodic payments anticipated during the
time that periodic payments are to be made. In the case of a fixed annuity
payment, the amount to be excluded in each year is determined by dividing the
"investment in the contract," adjusted by any refund feature, by the amount of
"expected return" during the time that periodic payments are to be made, and
then multiplying by the amount of the payment."

  When a payment under a Contract is made in a single sum, the amount of the
payment is taxed as ordinary income to the Owner or other payee to the extent it
exceeds the Owner's "investment in the contract."

 Partial Withdrawals Before Annuity Starting Date

  When a payment under a Contract, including a payment under a systematic
withdrawal plan, is less than the amount that would be paid upon the Contract's
complete surrender and such payment is made prior to the commencement of annuity
payments under the Contract, part or all of the payment (the partial withdrawal)
may be taxed to the Owner or other payee as ordinary income.

  On the date of the partial withdrawal, if the cash value of the Contract is
greater than the investment in the Contract, any part of such excess value so
withdrawn is subject to tax as ordinary income.

  If an individual assigns or pledges any part of the value of a Contract, the
value so pledged or assigned is taxed as ordinary income to the same extent as a
partial withdrawal.

 Penalty for Premature Withdrawals

  In addition to being included in ordinary income, the taxable portion of any
withdrawal may be subject to a 10-percent penalty tax. The penalty tax does not
apply to payments made to the Owner or other payee after the Owner attains age59
1/2, or on account of the Owner's death or disability. If the withdrawal is made
in substantially equal periodic payments over the life of the Annuitant or other
payee or over the joint lives of the Annuitant and the Annuitant's beneficiary
the penalty will also not apply.

DIVERSIFICATION REQUIREMENTS

  Each of the Portfolios of the Fund intends to qualify as a regulated
investment company under Subchapter M of the Code and will have to meet the
investment diversification tests of Section 817(h) of the Code and the
underlying regulations. The Treasury Department and the Internal Revenue Service
may, at some future time, issue a ruling or a regulation presenting situations
in which it will deem "investor control" to be present over the assets of the
underlying Portfolios, causing the Owner to be taxed currently on income
credited to the Contracts. In such a case, JHVLICO reserves the right to amend
the Contract or the choice of underlying Portfolios to avoid current taxation to
the Owners.

CONTRACTS PURCHASED UNDER INDIVIDUAL RETIREMENT ANNUITY PLANS (IRA)

  In general, the maximum amount of purchase payments deductible each year with
respect to an individual retirement annuity contract (as defined in Section 408
of the Code) issued on the life of an eligible purchaser is the lesser of $2,000
or 100% of compensation includible in gross income. A person may also purchase a
contract for the benefit of his or her spouse (including for example a homemaker
who does not work outside the home). Where an individual elects to deduct
amounts contributed on his or her own behalf and on behalf of a spouse, the
maximum amount of purchase payments deductible is $2,000 for each spouse if
their combined compensation is at least equal to the contributed amount.
However, not more than $2,000 can be allocated to either person's account. If an
individual or his or her spouse is an active participant in an
employer-sponsored retirement plan, the individual is permitted to make a
deductible purchase payment only if the adjusted gross incomes of the individual
and his or her spouse are below certain amounts.

  No deduction is allowed for purchase payments made in or after the taxable
year in which the Owner has attained the age of    

18    
<PAGE>
 
70 1/2 years nor is a deduction allowed for a "rollover contribution" as defined
in the Code.

  When payments under a Contract are made in the form of an annuity, or in a
single sum such as on surrender of the Contract or by partial withdrawal, the
payment is taxed as ordinary income.

  IRS required minimum distributions must begin no later than April 1 of the
year following the year in which the Owner attains age70 1/2. The Owner may
incur adverse tax consequences if a distribution on surrender of the Contract or
by partial withdrawal is made prior to his attaining age59 1/2, except in the
event of his death or total disability or certain other circumstances.

  Certain tax laws require 20% withholding on certain distributions from
individual retirement annuity contract plans. An Owner wishing to rollover his
entire distribution should have it paid directly to the successor plan.
Otherwise, the Owner's distribution may be reduced by the 20% mandatory income
tax. Consult a qualified tax adviser before taking such a distribution.
   
CONTRACTS PURCHASED UNDER NON-DEDUCTIBLE IRAS (ROTH IRAS)

  In general, for years after 1997, an individual may make purchase payments of
up to $2,000 each year for a new type of non-deductible IRA, known as a ROTH
IRA. This $2,000 maximum on purchase payments applies to all of an individual's
annual IRA contributions (deductible and non-deductible), except for reliever
contributions. The maximum amount that can be made to a ROTH IRA is phased out
for adjusted gross incomes between $95,000 and $110,000 in the case of single
taxpayers, between $150,000 and $160,000 in the case of married taxpayers filing
jointly, and between $0 and $15,000 in the case of married taxpayers filing
separately.

  "Qualified distributions" for ROTH IRAs are not includible in gross income or
subject to the penalty tax on early withdrawals. As defined in Section 408A of
the Code, a qualified distribution requires that the individual has held the
ROTH IRA for at least five years and, in addition, that the distribution is made
after the individual reaches age 59-1/2, on the individual's death or
disability, or to a qualified first-time home purchaser, subject to a $10,000
lifetime maximum, for the individual, a spouse, a child, a grandchild, or an
ancestor. Non-qualified distributions are treated as being made from
contributions first. When all distributions exceed the amount of contributions,
the excess is includible in gross income. The age 70-1/2 pre-death distribution
rules do not apply to ROTH IRAs.

  An individual may make a rollover contribution from a non-ROTH IRA, unless the
individual has adjusted gross income over $100,000 or the individual is a
married taxpayer filing a separate return. The individual must pay tax on any
portion of the IRA being rolled over that represents income on a previously
deductible IRA contribution. For rollovers in 1998, the individual may pay that
tax ratably in 1998 and over the succeeding three years. There are no similar
limitations on rollovers from a ROTH IRA to another ROTH IRA.    

WITHHOLDING OF TAXES

  JHVLICO is obligated to withhold taxes from certain payments unless the
recipient elects otherwise. The withholding rate varies depending upon the
nature and the amount of the distribution. JHVLICO will notify the Owner or
other payee in advance of the first payment of his or her right to elect out of
withholding and furnish a form on which the election may be made. Any election
must be received by JHVLICO in advance of the payment in order to avoid
withholding.

SEE YOUR OWN TAX ADVISER

  The above description of Federal income tax consequences of owning a Contract
is only a brief summary and is not intended as tax advice. Nor does it include a
discussion of Federal estate and gift tax or state tax consequences. Tax laws
and regulations are subject to change and such changes may be retroactive.
Anything less than full compliance with the applicable rules can have adverse
tax consequences. For example, premature withdrawals are generally subject to a
10-percent penalty tax. The taxation of an Annuitant or other payee has become
so complex and confusing that great care must be taken to avoid pitfalls. For
further information a prospective purchaser should consult a qualified tax
adviser.

                                   PERFORMANCE

  The Account may, from time to time, advertise certain performance information
with respect to its subaccounts. THE PERFORMANCE INFORMATION IS BASED ON
HISTORICAL INVESTMENT EXPERIENCE OF THE SUBACCOUNTS AND DOES NOT INDICATE OR
REPRESENT FUTURE PERFORMANCE.

  The subaccounts may include total return in advertisements. When a subaccount
advertises its total return, it will usually be calculated for one year, five
years, and ten years or for the life of the applicable portfolio. Total return
is the percentage change between the value of a hypothetical investment in the
subaccount at the beginning of the relevant period to the value of the
investment at the end of the period. Total return at the Account level reflects
all Contract charges (other than premium tax charges)--mortality and expense
risk charges, administrative service charge, and the annual contract fee--and is
therefore lower than total return at the Fund level where no comparable charges
have been deducted. Because the Contracts have not yet been offered, a total
return figure does not necessarily correspond to the total return actually
earned by any Contract Owner.

  The Money Market Subaccount may advertise "current yield" and "effective
yield." Current yield refers to the income earned by the subaccount over a
seven-day period and then annualized; i.e., the income earned in the period is
assumed to be earned every seven days over a 52-week period and stated as a    

                                                                          19    
<PAGE>
 
percentage of the investment. Effective yield is calculated similarly but, when
annualized, the income earned by the investment is assumed to be reinvested in
the subaccount and thus compounded in the course of a 52-week period. The
effective yield will be slightly higher than the current yield because of this
compounding effect of the assumed reinvestment.

  The other subaccounts may also advertise current yield. For these subaccounts,
the current yield will be calculated by dividing the annualization of the income
earned by the subaccount during a recent thirty-day period by the maximum
offering price per unit at the end of such period. In all cases, current yield
and effective yield reflect the recurring charges on the Account level including
the annual contract fee but do not reflect any premium tax charge.

  Performance information for the subaccounts may be compared to other variable
annuity separate accounts or other investment products surveyed by Lipper
Analytical Services, Inc., an independent service which monitors and ranks the
performance of investment companies, or tracked by other rating services,
companies, publications, or persons who independently monitor and rank
investment company performance. Performance figures are calculated in accordance
with standardized methods established by each reporting service.

                                STATE REGULATION

  JHVLICO is subject to the provisions of the Massachusetts insurance laws
applicable to stock life insurance companies and to regulation and supervision
by the Massachusetts Commissioner of Insurance. JHVLICO is also subject to the
applicable insurance laws of all the other states and jurisdictions in which it
does an insurance business.

                                     REPORTS

  Reports will be furnished at least annually to an Owner showing the number and
value of Accumulation Shares credited to the variable annuity contract and
containing the financial statements of the Fund.

                                VOTING PRIVILEGES

  All of the assets in the subaccounts of the Account are invested in shares of
the corresponding Portfolios of the Fund. JHVLICO will vote the shares of each
of the Portfolios of the Fund which are deemed attributable to qualifying
variable annuity contracts and variable life insurance policies at meetings of
the Fund's shareholders in accordance with instructions received from owners of
such contracts or policies. Shares of the Fund held in the Account which are not
attributable to such contracts or policies and those for which instructions from
owners are not received will be represented by JHVLICO at the meeting and will
be voted for and against each matter in the same proportion as the votes based
upon the instructions received from the owners of all such contracts and
policies.

  The number of Fund shares held in each subaccount deemed attributable to each
owner is determined by dividing a Contract's Accumulation Share Value (or for a
Contract under which annuity payments have commenced, the equivalent) in the
subaccount by the net asset value of one share in the corresponding Fund
Portfolio in which the assets of that subaccount are invested. Fractional votes
will be counted. The number of shares as to which the owner may give
instructions will be determined as of the record date for the Fund's meeting.

  Owners of Contracts may give instructions regarding the election of the Board
of Trustees of the Fund, ratification of the selection of independent auditors,
approval of the Fund's investment management agreement and other matters
requiring a vote under the 1940 Act. Owners will be furnished information and
forms by JHVLICO in order that voting instructions may be given.

                CHANGES IN APPLICABLE LAW--FUNDING AND OTHERWISE

  The voting privileges described in this prospectus are afforded based on
JHVLICO's understanding of applicable Federal securities law requirements. To
the extent that applicable law, regulations or interpretations change to
eliminate or restrict the need for such voting privileges, JHVLICO reserves the
right to proceed in accordance with any such revised requirements. JHVLICO also
reserves the right, subject to compliance with applicable law, including
approval of Owners if so required, to transfer assets determined by JHVLICO to
be associated with the class of contracts to which the Contracts belong from the
Account to another separate account or subaccount by withdrawing the same
percentage of each investment in the Account with appropriate adjustments to
avoid odd lots and fractions.

                                  LEGAL MATTERS
   
  The legal validity of the Contracts has been passed upon by Sandra M. DaDalt,
Counsel for JHVLICO.    

                          DISTRIBUTION OF THE CONTRACTS

                            IMPACT OF YEAR 2000 ISSUE

  The advent of the Year 2000 presents a technological challenge to JHVLICO. In
close cooperation with John Hancock Mutual Life Insurance Company, its ultimate
parent, JHVLICO has developed a plan to modify or replace significant portions
of JHVLICO's computer information and automated technologies so that its systems
will function properly with respect to dates in the year 2000 and thereafter.
  The plan also involves coordination and testing with business partners to
ensure that external factors do not adversely impact JHVLICO's systems. JHVLICO
presently believes that with modifications to existing systems and conversions
to new technologies, the year 2000 will not pose significant operational
problems for its computer systems. However, if certain modifications and
conversions are not made, or are not completed on time, the year 2000 issue
could have an adverse impact on the operations of JHVLICO.

  JHVLICO expects the project to be substantially complete by early 1999. This
completion target was derived utilizing numerous assumptions of future events,
including availability of certain resources and other factors. However, there
can be no guarantee that this estimate will be achieved, that these steps will
be sufficient or that actual results may not differ materially from those
anticipated.

  Because of exemptive and exclusionary provisions, interests in JHVLICO's
general account have not been registered under the Securities Act of 1933 and
the general account has not been registered as an investment company under the
1940 Act. Accordingly, neither the general account nor any interests therein are
subject to the provisions of these Acts, and JHVLICO has been advised that the
staff of the Commission has not reviewed the disclosure in this Prospectus
relating to the Fixed Account. Disclosure regarding the Fixed Account may,
however, be subject to certain generally-applicable provisions of the Federal
securities laws relating to accuracy and completeness of statements made in
prospectuses.

              APPENDIX--THE FIXED ACCOUNT AND FIXED ACCOUNT VALUE

INVESTMENTS IN THE FIXED ACCOUNT

  Net purchase payments will be allocated to the Fixed Account in accordance
with the selection made by the Owner in the application. The Owner may change
such selection by notice satisfactory to JHVLICO at its Service Center. Any
selection must specify what percentage of the purchase payment is to be
allocated to the Fixed Account. The percentage must be a whole number.

  The Value in the Fixed Account, at any time prior to annuitization, is equal
to:

     (a) net purchase payments allocated to the Fixed Account; plus

     (b) Variable Account Value (amounts held in the subaccounts of the Variable
  Account) transferred to the Fixed Account; plus

     (c) interest credited on amounts held in the Fixed Account; less

     (d) any prior partial withdrawals from the Fixed Account; less

     (e) amounts transferred out of the Fixed Account to the Variable Account;
  less

     (f) any applicable charges deducted from the Fixed Account.

INTEREST TO BE CREDITED

  Prior to annuitization, JHVLICO will credit interest (calculated on a compound
basis) to purchase payments allocated to the Fixed Account at rates declared by
JHVLICO, subject to a minimum rate of 3%. For purposes of this section, Variable
Account Value transferred to the Fixed Account shall be treated as a purchase
payment.

  Under current practice, the interest rate credited to amounts held in the
Fixed Account will be based on the size of the initial payment to the Contract.
If the initial payment was $10,000 or more, a higher interest rate will be
credited. The rate of interest credited on each amount may vary based upon when
that amount was first allocated to the Fixed Account.

TRANSFER AND REDUCTIONS OF FIXED ACCOUNT VALUE

  The Owner may transfer Fixed Account Value to one or more subaccounts of the
Variable Account or may transfer Variable Account Value into the Fixed Account.
The maximum amount that may be transferred into the Fixed Account in a Contract
Year is $100,000, less any premiums previously deposited into the Fixed Account
in such Contract Year (exclusive of any initial deposit made to the Fixed
Account at the time the Contract is issued); such initial deposit may be as
large as $500,000. After the tenth Contract Year, no deposits or transfers may
be made into the Fixed Account. JHVLICO may waive these limits.

  Sums on deposit in the subaccounts may be transferred into the Fixed Account
up to twelve times within a Contract Year during the accumulation period, but
not within six months of a transfer out of the Fixed Account. Transfers out of
the Fixed Account may be made only once in a Contract Year and only on or within
30 days after a Contract anniversary. No more than the greater of 20% of the
Fixed Account Value or $500 may be transferred out of the Fixed Account per
Contract Year without our prior approval. After annuitization, the amount of any
fixed annuity allocation may not be changed.

  Transfers will be made after receipt of notice satisfactory to JHVLICO at its
Service Center. Transfer requests received by JHVLICO before 4:00 p.m. Eastern
Time on a business day will be valued as of the close of that day. Any requests
received after 4:00 p.m. or on a non-business day will be valued as of the close
of the next business day.
   
  An Owner may request a transfer in writing or, once a written telephone
transfer authorization form is completed by the Owner, the Owner may request a
transfer by telephoning JHVLICO at 800-741-8184 or by sending a written request
via the JHVLICO fax machine at 888-553-4732. Any written request should include
the Owner's name, daytime telephone number, and contract number as well as the
names of the subaccounts or Fixed Account from which and to which money will be
transferred. JHVLICO reserves the right to modify, suspend, or terminate
telephone transfers at any time without notice to the Owners. If the fax request
option becomes unavailable, another means of telecommunication will be
substituted.    

  An Owner who authorizes telephone transfers will be liable for any loss,
expense or cost arising out of any unauthorized or fraudulent telephone transfer
instructions which JHVLICO reasonably believes to be genuine, unless such loss,
expense or cost is the result of JHVLICO's mistake or negligence. JHVLICO
employs procedures which provide safeguards against the execution of
unauthorized transfers, and which are reasonably designed to confirm that
transfer instructions received by telephone are genuine. These procedures
include requiring personal identification, tape recording calls, and providing
written confirmation to the Owner. If JHVLICO does not employ    

22    
<PAGE>
 
reasonable procedures to confirm that instructions communicated by telephone are
genuine, it may be liable for any loss due to unauthorized or fraudulent
instructions.

FIXED ANNUITY PAYMENT VALUES

  The dollar amount of each fixed annuity payment will be determined by dividing
the amount applied under the fixed annuity option (net of any applicable premium
taxes) by $1,000 and multiplying the result by the greater of: (a) the
applicable factor shown in the appropriate table in the Contract; or (b) the
factor currently offered by JHVLICO at the time of annuitization. This current
factor may be based on the sex of the payee unless prohibited by law.

   APPENDIX--VARIABLE ANNUITY INFORMATION FOR INDIVIDUAL RETIREMENT ANNUITIES

  To help you understand your purchase of this Contract as an Individual
Retirement Annuity (IRA), we are providing the following summary.

  I. Accumulation Shares--Each net purchase payment you make into your Contract
 is allocated to the subaccounts you select, and Accumulation Shares are
 purchased. This is the unit of measurement used to determine the value of your
 Contract. The number of shares purchased in any subaccount is based on the
 share value of that subaccount next determined after receipt of the payment at
 our Service Center. The values of shares fluctuate with the daily investment
 performance of the corresponding subaccount. The growth in the value of your
 Contract, to the extent invested in the Separate Account, is neither guaranteed
 nor projected and varies with the investment Portfolio you have selected. Each
 net purchase payment allocated to the Fixed Account will be credited interest,
 as determined by JHVLICO. The minimum guarantee rate is 3%. More details appear
 under "Accumulation Shares" in this Prospectus and in the "Appendix--The Fixed
 Account and Fixed Account Value."

  II. Separate Account and Series Fund Charges--The assets of the Separate
 Account are charged for services and guarantees. The annualized charge equals
 1.00%. Fees varying by Portfolio are charged against the Series Fund for
 investment management and advisory services. Details appear under "Charges
 Under the Annuity Contracts" in this Prospectus and "Management of the Fund" in
 the accompanying Series Fund prospectus.

  III. Deductions from the Contract--The full amount of each deposit is applied
 to the Contract. At or after the purchase date, one or more of the following
 charges may be made, depending on circumstances.

     1. CONTRACT FEE--JHVLICO currently deducts $30 from the Accumulated Value
  of the Contract as a contract fee if the Accumulated Value is less than
  $10,000. This occurs annually or at the time of surrender. Please refer to
  "Charges for Administrative Services" in this Prospectus.

     2. STATE PREMIUM TAX--Some states and local governments impose a premium or
  similar tax on annuities. JHVLICO only deducts this tax when required to do
  so. Please refer to "Premium or Similar Taxes" in this Prospectus.
   

                                                                          23

      APPENDIX--ILLUSTRATIVE ACCUMULATED VALUE AND ANNUITY PAYMENT TABLES

  The following Tables present illustrative periodic Accumulated Values and
annuity payments that would have resulted under a Contract described in this
prospectus had such values and payments been based exclusively upon the
investment experience of the seven specified subaccounts, assuming investment by
each of those subaccounts in the related Portfolio in the Fund and its
predecessors during the periods shown. The other subaccounts are not
illustrated, because of the limited time that they and their related Fund
Portfolios have been available. The Contracts described in this prospectus will
be first offered in 1997.

  For years ended December 31, 1986, and prior thereto, values have been
calculated based upon the actual investment results of the three corresponding
variable life insurance managed separate accounts which were the predecessors to
the Growth & Income, Sovereign Bond, and Money Market Portfolios, as if the Fund
had been in existence prior to March 28, 1986, the date of its reorganization.

  The Tables assume investment of a single purchase payment of $10,000, net of
any deductions from purchase payments, and that charges under the Contracts have
been made at an annual rate of 1.00% for mortality and expense risks and
administrative services. The tables also reflect actual investment management
fees and other portfolio expenses for the periods illustrated. Absent expense
reimbursements by John Hancock to certain of the Portfolios for some periods,
the values illustrated would have been lower.

WHAT THE TABLES ILLUSTRATE

  Subject to the foregoing, each Table I presents for the periods shown the
illustrative periodic Accumulated Values for each Account which would have
resulted at yearly intervals under a Contract where a net single purchase
payment of $10,000 was made, based upon the investment performance of the
applicable funding medium.

  Subject to the foregoing, each Table II indicates, at annual intervals,
illustrative monthly variable annuity payments for each subaccount which would
have been received by an Annuitant or other payee, assuming that an initial
annuity payment of $100 was received in the month and year indicated in the
respective Tables. The form of annuity illustrated is a life annuity with
payments guaranteed for 10 years.

  The results shown should not be considered a representation of the future. A
program of the type illustrated in the Tables does not assure a profit or
protect against depreciation in declining markets.

  As of March 30, 1998, the number of Contract Owners of all forms of the 
Contracts offered by the Account was 33,295.
 
ITEM 28. INDEMNIFICATION
 
  Article X of the By-Laws of JHVLICO provides indemnification to each present
and former trustee, officer, and employee of JHVLICO against litigation
expenses and liabilities incurred while acting as such, subject to limitations
of law, including under the Act. No indemnification shall be paid if a
director or officer is finally adjudicated not to have acted in good faith in
the reasonable belief that his action was in the best interest of JHVLICO.
JHVLICO may pay expenses incurred in defending an action or claim in advance
of its final disposition, but only upon receipt of an undertaking by the
person indemnified to repay such amounts if he or she should be determined not
be entitled to indemnification.
 
  Reference is made to Article VI of the ByLaws of the Fund, filed as Exhibit
2 to Post Effective Amendment No. 2 to the Fund's Registration Statement (File
No. 33-2081) dated April 12, 1988, which provides that the Fund shall
indemnify or advance any expenses to the trustees, shareholders, officers, or
employees of the Fund to the extent set forth in the Declaration of Trust.
 
  Sections 6.3 through 6.17 of the Declaration of Trust, included as Exhibit 1
to the Fund's Post Effective Amendment No. 2, relate to the indemnification of
trustees, shareholders, officers, and employees. It is provided that the
Registrant shall indemnify any trustee made a party to any proceeding by
reason of service in that capacity if the trustee (a) acted in good faith and
(b) reasonably believed, (1) in the case of conduct in the trustee's official
capacity with the Fund, that the conduct was in the best interest of the Fund
and (2) in all other cases, that the conduct was at least not opposed to the
best interests of the Fund, and (c) in the case of any criminal proceeding,
the Fund shall indemnify the trustee if the trustee acted in good faith and
had no reasonable cause to believe that the conduct was unlawful.
Indemnification may not be made by the Fund unless authorized in each case by
a determination by the Board of Trustees or by special legal counsel or by the
shareholders. Neither indemnification nor advancement of expenses may be made
if the trustee or officer has incurred liability by reason of willful
misfeasance, bad faith, gross negligence, or reckless disregard of duties
involved in the conduct of his office ("Disabling Conduct"). The means for
determining whether indemnification shall be made shall be (1) a final
decision on the merits by a court or other body before whom the proceeding was
brought that the person to be indemnified was not liable by reason of
Disabling Conduct or (2) in the absence of such a decision, a reasonable
determination, based upon a review of the facts, that such person was not
liable by reason of Disabling Conduct. Such latter determination may be made
either (a) by the vote of a majority of a quorum of Trustees of the Fund who
are neither "interested" persons of the Fund (as defined in the Act) nor
parties to the proceeding or (b) by an independent legal counsel in a written
opinion. The advancement of legal expenses may not occur unless the trustee or
officer agrees to repay the advance (unless it is ultimately determined that
he is entitled to indemnification) and at least one of three conditions is
satisfied: (1) he provides security for his agreement to repay, (2) the Fund
is insured against loss by reason of lawful advances, or (3) a majority of a
quorum of the Trustees of the Fund who are not interested persons and are not
parties to the proceedings, or independent counsel in a written opinion,
determine that there is reason to believe that the trustees or officer will be
found entitled to indemnification.
 
  Similar types of provisions dealing with the indemnification of the Fund's
officers and trustees are hereby incorporated by reference from documents
previously filed with the Commission, specifically, Section 14 of the
Investment Management Agreement by and between John Hancock Variable Series
Trust I and John Hancock Mutual Life Insurance Company (Exhibit 5.f. to Post-
Effective Amendment No. 4 to the Registration Statement of the Fund (File No. 
33-2081) dated April, 1989), Section 14 of the Investment Management Agreement
by and between John Hancock Variable Series Trust I and John Hancock Mutual Life
Insurance Company (Exhibit 5.a. to the Fund's Registration Statement (File No.
33-2081) dated December 11, 1985), Section 14 of the Investment Management
Agreement by and between John Hancock Variable Series Trust and John Hancock
Mutual Life Insurance Company (Exhibit 5.g. to Post-Effective Amendment No. 9 to
the Fund's Registration Statement (File No. 33-2081) dated March 2, 1994),
Section 14 of the Investment Management Agreement By and Between John Hancock
Variable Series Trust I and John Hancock Mutual Life Insurance Company (Exhibit
5.k. to Post-Effective Amendment No. 13 to the Fund's Registration Statement
(File No. 33-2081) dated April 30, 1996), Section 14 of the Investment
Management Agreement By and Between John Hancock Variable Series Trust I and
John Hancock Mutual Life Insurance Company (Exhibit 5.v. to Post-Effective

April 24, 1998, Section 7 of the Underwriting and Administrative Services
Agreement by

and between John Hancock Variable Series Trust I and John Hancock Mutual Life
Insurance Company (Exhibit 6 to Post-Effective Amendment No. 4 to the
Registration Statement of the Fund (File No. 33-2081) dated April, 1986, 
Section 15 of the Transfer Agency Agreement by and between John Hancock
Variable Series Trust I and John Hancock Mutual Life Insurance Company
(Exhibit 9 to Pre-Effective Amendment No. 1 to the Registration Statement of
the Fund (File No. 33-2081) dated March 13, 1986), and Section 6 of the 
Underwriting and Indemnity Agreement By and Among John Hancock Series Trust I, 
John Hancock Distributors, Inc., and John Hancock Mutual Life Insurance Company
(Exhibit 6.b. to Post-Effective Amendment No. 14 to Form N-1A Registration
Statement of the Fund (File No. 33-2081) filed February 28, 1997).
 
  Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers, and controlling persons of
the Registrant pursuant to the foregoing provisions or otherwise, the
Registrant has been advised that, in the opinion of the Securities and
Exchange Commission, such indemnification is against public policy as
expressed in that Act and is, therefore, unenforceable. In the event that a
claim for indemnification against such liabilities (other than the payment by
the Registrant of expenses incurred or paid by a director, officer or
controlling person of the Registrant in the successful defense of any action,
suit, or proceeding) is asserted by such director, officer, or controlling
person in connection with the securities being registered, the Registrant
will, unless in the opinion of its counsel the matter has been settled by a
controlling precedent, submit to a court of appropriate jurisdiction the
question of whether indemnification by it is against public policy as
expressed in that Act and will be governed by the final adjudication of such
issue.

                        CALCULATION OF PERFORMANCE DATA
 
  The Account will show the average annual total return for each subaccount,
according to the following formula prescribed by the Securities and Exchange
Commission:
 
                                P(1 + T)n ^ ERV
 
<TABLE>
   <C>    <C> <C> <S>
   where:   P   ^ a hypothetical initial payment of $1,000
            T   ^ average annual total return
            n   ^ number of years
          ERV   ^ ending redeemable value of a hypothetical $1,000 payment,
                  made at the beginning of a period (or fractional portion
                  thereof)
</TABLE>
 
  Average annual total return is the annual compounded rate of return that
would have produced the cash redemption value under a Contract had the
subaccount been invested in a specified Portfolio of the Fund (or its
predecessor) over the stated period and had the performance remained constant
throughout. The calculation assumes a single $1,000 payment made at the
beginning of the period and full redemption at the end of the period. It
reflects adjustments for all Fund and Contract level charges except premium
taxes, if any.
   
  On that basis, the following table shows the average annual total return for
each subaccount for the periods ended December 31, 1997:

*** Absent expense reimbursements from John Hancock to certain Portfolios for
    some periods, total return figures for the related subaccounts would have
    been lower.
 
  The Account will show current yield and effective yield figures for the
Money Market Subaccount. The current yield of the Money Market Subaccount for
a seven-day period (the "base period") will be computed by determining the
"net change in value" (calculated as set forth below) of a hypothetical
account having a balance of one share at the beginning of the period, dividing
the net change in account sales by the value of the account at the beginning
of the base period to obtain the base period return, and multiplying the base
period return by
 
                                       3
<PAGE>
 
365/7 with the resulting yield figure carried to the nearest hundredth of one
percent. Net changes in value of a hypothetical account will include net
investment income of the account (accrued daily dividends as declared by the
Money Market Portfolio, less daily expense charges of the Account) for the
period, but will not include realized gains or losses or unrealized
appreciation or depreciation on the underlying fund shares. Mortality and
expense risk and administrative charges are reflected, but any charge for
premium taxes are not.
 
  The effective yield reflects the effects of compounding and represents an
annualization of the current return with all dividends reinvested. The formula
for effective yield, as prescribed by the SEC, is:
 
         Effective yield = [(Base period return + 1)/365//7/] - 1
   
  For the 7-day period ending December 31, 1997, the Money Market Subaccount's
current yield was 4.47% and its effective yield was 4.57%.     
 
  The Account will calculate current yield for each of the other Subaccounts
according to the following formula prescribed by the SEC:
 
                 Yield    =   2 [([ (a - b)/cd]   + 1)/6/   -  1]
                                    -----------
 

   where:   a   = dividends and interest earned during the period
            b   = expenses accrued for the period (net of reimbursements)
            c   = the average daily number of shares outstanding during the
                  period that were entitled to received dividends
            d   = the maximum offering price per share on the last day of the
                  period.
 
  According to this formula, yield is determined by dividing the net
investment income per Accumulation Share earned during the period (minus the
deduction for mortality and expense risk charge, contract fee, administrative
services charge) by the Accumulation Share Value on the last day of the period
and annualizing the resulting figure. The calculation is based on specified
30-day periods identified in the advertisement.
 
                        CALCULATION OF ANNUITY PAYMENTS
 
  The variable monthly annuity payment to an Annuitant under a Contract is
equal to the sum of the products of the number of each subaccount's "Annuity
Units" credited to the Contract multiplied by the applicable "Annuity Unit
Value," as these terms are defined under "Special Terms" and "Variable Account
Valuation Procedures," respectively, in the Account's prospectus. The number
of each subaccount's Annuity Units credited to the Contract is multiplied by
the applicable Annuity Unit Value as of ten calendar days prior to the date
the payment is due. The value of the Annuity Units varies from day to day,
depending on the investment performance of the subaccount, the deductions made
against the subaccount, and the assumed investment rate used in computing
Annuity Unit Values. Thus, the variable monthly annuity payments vary in
amount from month to month.
 
  The amount of the initial variable monthly payment is determined on the
assumption that the actual net investment rate of each subaccount used in
calculating the Net Investment Factor (as described under "Variable Account
Valuation Procedures--Net Investment Factor" in the Account's prospectus) will
be equal on an annual basis to the assumed investment rate. If the actual net
investment rate between the dates for determining two monthly annuity payments
is greater than the assumed investment rate, the latter monthly payment will
be larger in amount than the former. On the other hand, if the actual net
investment rate between the dates for determining two monthly annuity payments
is less than the assumed investment rate, the latter monthly payment will be
smaller in amount than the former.
 
  The mortality tables used as a basis for the annuity purchase rates are the
1983a Mortality Tables, with projections of mortality improvements and with
certain age adjustments based on the Contract Year of
 
                                       4
<PAGE>
 
annuitization. The mortality table used in a Contract purchased in connection
with certain employer-related plans and used in all Contracts issued in
Montana and Massachusetts will be the Female Annuity Table of the 1983a
Mortality Tables. The impact of this change will be lower benefits (5% to 15%)
from a male's viewpoint than would otherwise be the case.
 
  An illustration of the method of calculation of variable monthly annuity
payments and the number of Annuity Units under deferred Contracts is shown in
the outline that follows.

B. HYPOTHETICAL EXAMPLE ILLUSTRATING THE CALCULATION OF ACCUMULATION SHARE
   VALUES AND ANNUITY UNIT VALUES
 
  Assume at the beginning of the Valuation Period being considered, the value
of the Subaccount was $4,000,000. Investment income during the Valuation
Period totaled $2000 while capital gains were $3000 and capital losses were
$1000. No taxes accrued. Charges against the beginning value of the Subaccount
amount to $164.40 assuming a one day Valuation Period. The $109.60 was
computed by multiplying the beginning Subaccount value of $4,000,000 by the
factor 0.00002740. By substituting in the first formula above, the net
investment rate is equal to $3890.40 ($2000 + $3000 - $1000 - $109.60) divided
by $4,000,000 or 0.0009726. The Net Investment Factor would then be 1.0009726.
 
  Assume further that each Accumulation Share had a value of $11.250000 on the
previous Valuation Date, and the value of an Annuity Unit on such date was
$1.0850000. Based upon the experience of the Subaccount during the Valuation
Period, the value of an Accumulation Share at the end of the Valuation Period
would be $11.260942 ($11.250000 x 1.0009726). The value of an Annuity Unit at
the end of the Valuation Period would be $1.085953 ($1.0850000 x 1.0009726 x
 .99990575). The final figure, .99990575, neutralizes the effect of a 3 1/2%
assumed investment rate so that the Annuity Unit recognizes only the actual
investment experience.

D. HYPOTHETICAL EXAMPLE ILLUSTRATING THE CALCULATION OF THE AMOUNT OF MONTHLY
   VARIABLE ANNUITY PAYMENT FOR DEFERRED CONTRACTS
 
  Assume that 10 days before the date of maturity a Contract has credited to
it 4000.000 Accumulation Shares each having a value of $12.000000. The
appropriate annuity purchase rate in the Contract for an assumed investment
rate of 3 1/2% is $5.47 per $1000 of proceeds for the Annuity Option elected.
The Annuitant's first monthly payment would then be $262.56.
 
<TABLE>
               <S>              <C>               <C>                      <C>               <C>
               4000.000           X               $12.000000                 X               5.47
               ----------------------------------------------
                               $1000
</TABLE>
   
  If the value of an Annuity Unit 10 days before the date of maturity was
$1.4000000, the number of Annuity Units represented by the first and
subsequent payments would be 187.543 ($262.56/$1.4000000). If the Annuity Unit
Value 10 days before the due date of the second monthly payment was $1.405000,
the amount of the second payment would be $263.50 (187.543 x $1.405000).

                         NOTES TO FINANCIAL STATEMENTS
 
                               DECEMBER 31, 1997
 
1. ORGANIZATION
 
  John Hancock Variable Annuity Account I (the Account) is a separate
investment account of John Hancock Variable Life Insurance Company (JHVLICO).
The Account was formed to fund variable annuity contracts (Contracts) issued
by JHVLICO. The Account is operated as a unit investment trust registered
under the Investment Company Act of 1940, as amended, and currently consists
of eighteen subaccounts. The assets of each subaccount are invested
exclusively in shares of a corresponding Portfolio of John Hancock Variable
Series Trust I (the Fund). New subaccounts may be added as new Portfolios are
added to the Fund or as other investment options are developed and made
available to contractowners. The eighteen Portfolios of the Fund which are
currently available are: Large Cap Growth, Sovereign Bond, International
Equities, Small Cap Growth, International Balanced, Mid Cap Growth, Large Cap
Value, Money Market, Mid Cap Value, Special Opportunities, Real Estate Equity,
Growth & Income, Managed, Short-Term U.S. Government, Small Cap Value,
International Opportunities, Equity Index and Strategic Bond Portfolios. Each
Portfolio has a different investment objective.
 
  The assets of the Account are the property of JHVLICO. The portion of the
Account's assets applicable to the Contracts may not be charged with
liabilities arising out of any other business JHVLICO may conduct.
 
2. SIGNIFICANT ACCOUNTING POLICIES
 
 Estimates
 
  The preparation of financial statements in conformity with generally
accepted accounting principles 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.
 
 Valuation of Investments
 
  Investment in shares of the Fund are valued at the reported net asset values
of the respective Portfolios. Investment transactions are recorded on the
trade date. Dividend income is recognized on the ex-dividend date. Realized
gains and losses on sales of Fund shares are determined on the basis of
identified cost.
 
 Federal Income Taxes
 
  The operations of the Account are included in the federal income tax return
of JHVLICO, which is taxed as a life insurance company under the Internal
Revenue Code. JHVLICO has the right to charge the Account any federal income
taxes, or provision for federal income taxes, attributable to the operations
of the Account or to the Contracts funded in the Account. Currently, John
Hancock does not make a charge for income or other taxes. JHVLICO retains the
right to charge the Account for any federal income taxes arising from changes
in the tax law. Charges for state and local taxes, if any, attributable to the
Account may also be made.
 
 Expenses
 
  JHVLICO assumes mortality and expense risks of the Contracts and provides
administrative services to the Account for which asset charges are deducted at
an annual rate of 1.5% of net assets of the Account.
 
  JHVLICO makes certain other deductions from contractowner payments for
premium taxes and sales and withdrawal charges, which are accounted for as a
reduction of net assets resulting from contractowner transactions.

  John Hancock acts as the distributor, principal underwriter and investment
advisor for the Fund. Certain officers of the Account are officers and
directors of JHVLICO or the Fund.
 
6. IMPACT OF YEAR 2000 (UNAUDITED)
 
  The John Hancock Variable Annuity Account I, along with John Hancock Mutual
Life Insurance Company, its ultimate parent (together, John Hancock), have
developed a plan to modify or replace significant portions of the Account's
computer information and automated technologies so that its systems will
function properly with respect to the dates in the year 2000 thereafter. The
Account presently believes that with modifications to existing systems and
conversions to new technologies, the year 2000 will not pose significant
operational problems for its computer systems. However, if certain
modifications and conversions are not made, or are not completed timely, the
year 2000 issue could have an adverse impact on the operations of the Account.
 
  John Hancock as early as 1994 had begun assessing, modifying and converting
the software related to its significant systems and has initiated formal
communications with its significant business partners and customers to
determine the extent to which John Hancock's interface systems are vulnerable
to those third parties' failure to remediate their own year 2000 issues. While
John Hancock is developing alternative third-party processing arrangements as
it deems appropriate, there is no guarantee that the systems of other
companies on which the Account's systems rely will be converted timely or will
not have an adverse effect on the Account's systems.
 
  The Account expects the project to be substantially complete by early 1999.
This completion target was derived utilizing numerous assumptions of future
events, including availability of certain resources and other factors.
However, there can be no guarantee that this completion target will be
achieved.

               REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS     
 
Board of Directors
John Hancock Variable Life Insurance Company
   
  We have audited the accompanying statutory-basis statements of financial
position of John Hancock Variable Life Insurance Company as of December 31,
1997 and 1996, and the related statutory-basis statements of operations and
unassigned deficit and cash flow for each of the three years in the period
ended December 31, 1997. These financial statements are the responsibility of
the Company's management. Our responsibility is to express an opinion on these
financial statements based on our audits.     
   
  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements. 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.     
          
  As described in Note 1 to the financial statements, the Company presents its
financial statements in conformity with accounting practices prescribed or
permitted by the Commonwealth of Massachusetts Division of Insurance, which
practices differ from generally accepted accounting principles. The variances
between such practices and generally accepted accounting principles also are
described in Note 1. The effects on the financial statements of these
variances are not reasonably determinable but are presumed to be material.
    
   
  In our opinion, because of the effects of the matter described in the
preceding paragraph, the financial statements referred to above do not present
fairly, in conformity with generally accepted accounting principles, the
financial position of John Hancock Variable Life Insurance Company at December
31, 1997 and 1996, or the results of its operations or its cash flows for the
three years ended December 31, 1997.     
   
  Also, in our opinion, the financial statements referred to above present
fairly, in all material respects, the financial position of John Hancock
Variable Life Insurance Company at December 31, 1997 and 1996, and the results
of its operations and its cash flows for each of the three years in the period
ended December 31, 1997 in conformity with accounting practices prescribed or
permitted by the Commonwealth of Massachusetts Division of Insurance.

JOHN HANCOCK VARIABLE LIFE INSURANCE COMPANY
 
NOTES TO STATUTORY-BASIS FINANCIAL STATEMENTS
 
NOTE 1--NATURE OF OPERATIONS AND SIGNIFICANT ACCOUNTING PRACTICES
 
John Hancock Variable Life Insurance Company (the Company) is a wholly-owned
subsidiary of John Hancock Mutual Life Insurance Company (John Hancock). The
Company, domiciled in the Commonwealth of Massachusetts, principally writes
variable and universal life insurance policies. Those policies primarily are
marketed through John Hancock's sales organization, which includes a career
agency system composed of company-owned, unionized branch offices and
independent general agencies. Policies also are sold through various
unaffiliated securities broker-dealers and certain other financial
institutions. Currently the Company writes business in all states except New
York.
 
The preparation of the financial statements of insurance companies requires
management to make estimates and assumptions that affect amounts reported in
the financial statements and accompanying notes. Such estimates and
assumptions could change in the future as more information becomes known,
which could impact the amounts reported and disclosed herein.
 
Basis of Presentation: The financial statements have been prepared using
accounting practices prescribed or permitted by the Commonwealth of
Massachusetts Division of Insurance and in conformity with the practices of
the National Association of Insurance Commissioners (NAIC), which practices
differ from generally accepted accounting principles (GAAP). The 1995
financial statements presented for comparative purposes were previously
described as being prepared in accordance with GAAP for stock life insurance
companies wholly-owned by a mutual life insurance company. Pursuant to
Financial Accounting Standards Board Interpretation 40, "Applicability of
Generally Accepted Accounting Principles to Mutual Life Insurance and Other
Enterprises" (FIN 40), as amended, which was effective for 1996 financial
statements, financial statements based on statutory accounting practices can
no longer be described as prepared in conformity with GAAP. Furthermore,
financial statements prepared in conformity with statutory accounting
practices for periods prior to the effective date of FIN 40 are not considered
GAAP presentations when presented in comparative form with financial
statements for periods subsequent to the effective date. Accordingly, the 1995
financial statements are no longer considered to be presented in conformity
with GAAP.
 
The significant differences from GAAP include: (1) policy acquisition costs
are charged to expense as incurred rather than deferred and amortized over the
related premium-paying period; (2) policy reserves are based on statutory
mortality, morbidity, and interest requirements without consideration of
withdrawals and Company experience; (3) certain assets designated as
"nonadmitted assets" are excluded from the balance sheet by direct charges to
surplus; (4) reinsurance recoverables are netted against reserves and claim
liabilities rather than reflected as an asset; (5) bonds held as available for
sale are recorded at amortized cost or market value as determined by the NAIC
rather than at fair value; (6) an Asset Valuation Reserve and Interest
Maintenance Reserve as prescribed by the NAIC are not calculated under GAAP.
Under GAAP, realized capital gains and losses are reported in the income
statement on a pretax basis as incurred and valuation allowances would be
provided when there has been a decline in value deemed other than temporary;
(7) investments in affiliates are carried at their net equity value with
changes in value being recorded directly to unassigned deficit rather than
consolidated in the financial statements; (8) no provision is made for the
deferred income tax effects of temporary differences between book and tax
basis reporting; and (9) certain items, including modifications to required
policy reserves resulting from changes in actuarial assumptions or increased
benefits, are recorded directly to unassigned deficit rather than being
reflected in income. The effects of the foregoing variances from GAAP have not
been determined but are presumed to be material.
 
The significant accounting practices of the Company are as follows:
 
Pending Statutory Standards: The NAIC currently is in the process of
recodifying statutory accounting practices, the result of which is expected to
constitute the only source of prescribed statutory accounting
 
                                      23

practices. Accordingly, that project, which is expected to be approved by the
NAIC in 1998 will likely change, to some extent, prescribed statutory
accounting practices, and may result in changes to the accounting practices
that the Company uses to prepare its statutory-basis financial statements. The
impact of any such changes on the Company's unassigned deficit is not expected
to be material.
 
Revenues and Expenses: Premium revenues are recognized over the premium-paying
period of the policies whereas expenses, including the acquisition costs of
new business, are charged to operations as incurred and policyholder dividends
are provided as paid or accrued.
 
Cash and Temporary Cash Investments: Cash includes currency on hand and demand
deposits with financial institutions. Temporary cash investments are short-
term, highly-liquid investments both readily convertible to known amounts of
cash and so near maturity that there is insignificant risk of changes in value
because of changes in interest rates.
 
Valuation of Assets: General account investments are carried at amounts
determined on the following bases:
 
  Bonds and stock values are carried as prescribed by the NAIC; bonds
  generally at amortized amounts or cost, preferred stocks generally at cost
  and common stocks at market. The discount or premium on bonds is amortized
  using the interest method.
 
  Investments in affiliates are included on the statutory equity method.
 
  Goodwill is amortized on a straight-line basis over a ten year period.
 
  Mortgage loans are carried at outstanding principal balance or amortized
  cost.
 
  Investment real estate is carried at depreciated cost, less encumbrances.
  Depreciation on investment real estate is recorded on a straight-line
  basis. Accumulated depreciation amounted to $2.1 million in 1997 and $1.2
  million in 1996.
 
  Real estate acquired in satisfaction of debt and held for sale is carried
  at the lower of cost or market as of the date of foreclosure.
 
  Policy loans are carried at outstanding principal balance, not in excess of
  policy cash surrender value.
 
Asset Valuation and Interest Maintenance Reserves: The Asset Valuation Reserve
(AVR) is computed in accordance with the prescribed NAIC formula and
represents a provision for possible fluctuations in the value of bonds, equity
securities, mortgage loans, real estate and other invested assets. Changes to
the AVR are charged or credited directly to the unassigned deficit.
 
The Company also records the NAIC prescribed Interest Maintenance Reserve
(IMR) that represents that portion of the after tax net accumulated
unamortized realized capital gains and losses on sales of fixed income
securities, principally bonds and mortgage loans, attributable to changes in
the general level of interest rates. Such gains and losses are deferred and
amortized into income over the remaining expected lives of the investments
sold. At December 31, 1997, the IMR, net of 1997 amortization of $1.2 million,
amounted to $7.8 million which is included in policy reserves. The
corresponding 1996 amounts were $1.2 million and $5.9 million, respectively.
 
Goodwill: The excess of cost over the statutory book value of the net assets
of life insurance business acquired was $13.1 million and $15.1 million at
December 31, 1997 and 1996, respectively, and generally is amortized over a
ten-year period using a straight-line method. Accumulated amortization was
$8.8 million and $6.7 million at December 31, 1997 and 1996, respectively.

NOTES TO STATUTORY-BASIS FINANCIAL STATEMENTS--CONTINUED
 
NOTE 1--NATURE OF OPERATIONS AND SIGNIFICANT ACCOUNTING PRACTICES--CONTINUED
 
Separate Accounts: Separate account assets and liabilities reported in the
accompanying statements of financial position represent funds that are
separately administered, principally for variable life insurance policies, and
for which the contractholder, rather than the Company, generally bears the
investment risk. Separate account obligations are intended to be satisfied
from separate account assets and not from assets of the general account.
Separate accounts generally are reported at market value. The operations of
the separate accounts are not included in the statement of operations;
however, income earned on amounts initially invested by the Company in the
formation of new separate accounts is included in other income.
 
Fair Values of Financial Instruments: Statement of Financial Accounting
Standards (SFAS) No. 107, "Disclosure about Fair Value of Financial
Instruments," requires disclosure of fair value information about financial
instruments, whether or not recognized in the statement of financial position,
for which it is practicable to estimate the value. In situations where quoted
market prices are not available, fair values are based on estimates using
present value or other valuation techniques. SFAS No. 107 excludes certain
financial instruments and all nonfinancial instruments from its disclosure
requirements. Therefore, the aggregate fair value amounts presented do not
represent the underlying value of the Company. See Note 11.
 
The methods and assumptions utilized by the Company in estimating its fair
value disclosures for financial instruments are as follows:
 
  The carrying amounts reported in the statement of financial position for
  cash and temporary cash investments approximate their fair values.
 
  Fair values for public bonds are obtained from an independent pricing
  service. Fair values for private placement securities and publicly traded
  bonds not provided by the independent pricing service are estimated by the
  Company by discounting expected future cash flows using current market
  rates applicable to the yield, credit quality and maturity of the
  investments.
 
  The fair values for common and preferred stocks, other than its subsidiary
  investments, which are carried at equity values, are based on quoted market
  prices.
 
  The fair value of interest rate swaps and currency rate swaps is estimated
  using a discounted cash flow method adjusted for the difference between the
  rate of the existing swap and the current swap market rate. Discounted cash
  flows in foreign currencies are converted to U.S. dollar using current
  exchange rates.
 
  The fair value for mortgage loans is estimated using discounted cash flow
  analyses using interest rates adjusted to reflect the credit
  characteristics of the loans. Mortgage loans with similar characteristics
  and credit risks are aggregated into qualitative categories for purposes of
  the fair value calculations.
 
  The carrying amount in the statement of financial position for policy loans
  approximates their fair value.
 
  The fair value for outstanding commitments to purchase long-term bonds and
  issue real estate mortgages is estimated using a discounted cash flow
  method incorporating adjustments for the difference in the level of
  interest rates between the dates the commitments were made and December 31,
  1997. The fair value for commitments to purchase real estate approximates
  the amount of the initial commitment.
 
Capital Gains and Losses: Realized capital gains and losses are determined
using the specific identification basis. Realized capital gains and losses,
net of taxes and amounts transferred to the IMR, are included in net gain or
loss. Unrealized gains and losses, which consist of market value and book
value adjustments, are shown as adjustments to the unassigned deficit.
 
Policy Reserves: Life reserves are developed by actuarial methods and
determined based on published tables using statutorily specified interest
rates and valuation methods that will provide, in the aggregate, reserves that
 
                                      25

NOTE 1--NATURE OF OPERATIONS AND SIGNIFICANT ACCOUNTING PRACTICES--CONTINUED
 
are greater than or equal to the minimum or guaranteed policy cash values or
amounts required by the Commonwealth of Massachusetts Division of Insurance.
Reserves for variable life insurance policies are maintained principally on
the modified preliminary term method using the 1958 and 1980 Commissioner's
Standard Ordinary (CSO) mortality tables, with an assumed interest rate of 4%
for policies issued prior to May 1, 1983 and 4 1/2% for policies issued on or
thereafter. Reserves for single premium policies are determined by the net
single premium method using the 1958 CSO mortality table, with an assumed
interest rate of 4%. Reserves for universal life policies issued prior to 1985
are equal to the gross account value which at all times exceeds minimum
statutory requirements. Reserves for universal life policies issued from 1985
through 1988 are maintained at the greater of the Commissioner's Reserve
Valuation Method (CRVM) using the 1958 CSO mortality table, with 4 1/2%
interest or the cash surrender value. Reserves for universal life policies
issued after 1988 and for flexible variable policies are maintained using the
greater of the cash surrender value or the CRVM method with the 1980 CSO
mortality table and 5 1/2% interest for policies issued from 1988 through
1992; 5% interest for policies issued in 1993 and 1994; and 4 1/2% interest
for policies issued in 1995 through 1997.
 
Federal Income Taxes: Federal income taxes are reported in the financial
statements based on amounts determined to be payable as a result of operations
within the current accounting period. The operations of the Company are
consolidated with John Hancock in filing a consolidated federal income tax
return for the affiliated group. The federal income taxes of the Company are
allocated on a separate return basis with certain adjustments. The Company
made payments of $29.6 million in 1997, $33.5 million in 1996 and $32.2
million in 1995.
 
Income before taxes differs from taxable income principally due to tax-exempt
investment income, the limitation placed on the tax deductibility of
policyholder dividends, accelerated depreciation, differences in policy
reserves for tax return and financial statement purposes, capitalization of
policy acquisition expenses for tax purposes and other adjustments prescribed
by the Internal Revenue Code.
 
Adjustments to Policy Reserves: From time to time, the Company finds it
appropriate to modify certain required policy reserves because of changes in
actuarial assumptions or increased benefits. Reserve modifications resulting
from such determinations are recorded directly to the unassigned deficit.
During 1997, the Company refined certain actuarial assumptions inherent in the
calculation of reserves related to AIDS claims under individual life policies,
resulting in a $6.4 million increase in the unassigned deficit at December 31,
1997. During 1996 and 1995, there were no refinements in actuarial assumptions
inherent in the calculation of policy reserves.
 
Reinsurance: Premiums, commissions, expense reimbursements, benefits and
reserves related to reinsured business are accounted for on bases consistent
with those used in accounting for the original policies issued and the terms
of the reinsurance contracts. Premiums ceded to other companies have been
reported as a reduction of premium income. Amounts applicable to reinsurance
ceded for future policy benefits, unearned premium reserves and claim
liabilities have been reported as reductions of these items.
 
Reclassifications: Certain 1995 amounts have been reclassified to permit
comparison with the corresponding 1996 and 1997 amounts.
 
NOTE 2--ACQUISITION
 
On June 23, 1993, the Company acquired all of the outstanding shares of stock
of Colonial Penn Annuity and Life Insurance Company (CPAL) from Colonial Penn
Life Insurance Company, for an aggregate purchase price of approximately $42.5
million. At the date of acquisition, assets of CPAL were approximately $648.5
million, consisting principally of cash and temporary cash investments and
liabilities were approximately $635.2 million,

consisting principally of reserves related to a block of interest sensitive
single-premium whole life insurance business assumed by CPAL from Charter
National Life Insurance Company (Charter). The purchase price includes
contingent payments of up to approximately $7.3 million payable between 1994
and 1998 based on the actual lapse experience of the business in force on June
23, 1993. The Company made contingent payments to CPAL of $1.5 million during
each of 1997, 1996, and 1995. Unamortized goodwill of $13.1 at December 31,
1997 is being amortized over ten years on a straight-line basis.
 
On June 24, 1993, the Company contributed $24.6 million in additional capital
to CPAL. CPAL was renamed John Hancock Life Insurance Company of America
(JHLICOA) on July 7, 1993. JHLICOA manages the business assumed from Charter
and does not currently issue new business.

operations. The amount of the service fee charged to the Company was $123.6
million, $111.7 million, and $97.9 million in 1997, 1996, and 1995,
respectively, which has been included in insurance and investment expenses.
The Parent has guaranteed that, if necessary, it will make additional capital
contributions to prevent the Company's stockholder's equity from declining
below $1.0 million.
 
The service fee charged to the Company by the Parent includes $0.9 million,
$1.6 million, and $1.8 million for the years ended December 31, 1997, 1996,
and 1995 respectively, representing the portion of the provision for retiree
benefit plans determined under the accrual method, including a provision for
the 1993 transition liability which is being amortized over twenty years, that
was allocated to the Company.
 
The Company has a modified coinsurance agreement with John Hancock to reinsure
50% of 1994 through 1997 issues of flexible premium variable life insurance
and scheduled premium variable life insurance policies. In connection with
this agreement, John Hancock transferred $22.0 million, $24.5 million and
$32.7 million of cash for tax, commission, and expense allowances to the
Company, which increased the Company's net gain from operations by $10.1
million, $15.7 million, and $20.3 million in 1997, 1996, and 1995,
respectively.
 
The Company has a modified coinsurance agreement with John Hancock to reinsure
50% of 1995 through 1997 issues of retail annuity contracts (Independence
Preferred and Declaration). In connection with this agreement, John Hancock
made a net cash payment of $1.1 million and received a net cash payment of
$35.0 million for surrender benefits, tax, reserve increase, commission,
expense allowances and premium to the Company, which increased the Company's
net gain from operations by $9.8 million and $15.1 million in 1997 and 1996,
respectively.
 
Effective January 1, 1997, the Company entered into a stop-loss agreement with
John Hancock to reinsure mortality claims in excess of 110% of expected
mortality claims in 1997 for all policies that are not reinsured under any
other indemnity agreement. In connection with the agreement, John Hancock
transferred $2.4 million of cash for mortality claims to the Company, which
increased the Company's net gain from operations by $1.3 million.

At December 31, 1997, the fair values of the commercial and agricultural
mortgage loans portfolios were $243.8 million and $42.0 million, respectively.
The corresponding amounts as of December 31, 1996 were approximately $189.0
million and $30.4 million, respectively. The corresponding amounts as of
December 31, 1995 were approximately $132.1 million and $22.2 million,
respectively.
 
The maximum and minimum lending rates for mortgage loans during 1997 were
10.49% and 8.14% for agricultural loans and 8.53% and 7.42% for other
properties. Generally, the maximum percentage of any loan to the value of
security at the time of the loan, exclusive of insured or guaranteed or
purchase money mortgages, is 75%. For city mortgages, fire insurance is
carried on all commercial and residential properties at least equal to the
excess of the loan over the maximum loan which would be permitted by law on
the land without the building, except as permitted by regulations of the
Federal Housing Commission on loans fully insured under the provision of the
National Housing Act. For agricultural mortgage loans, fire insurance is not
normally required on land based loans except in those instances where a
building is critical to the farming operation. Fire insurance is required on
all agri-business facilities in an aggregate amount equal to the loan balance.
 
NOTE 7--REINSURANCE
 
The Company cedes business to reinsurers to share risks under variable life,
universal life and flexible variable life insurance policies for the purpose
of reducing exposure to large losses. Premiums, benefits and reserves ceded to
reinsurers during the year ended December 31, 1997 were $427.4 million, $18.3
million, and $10.1 million, respectively. The corresponding amounts in 1996
were $384.3 million, $9.9 million, and $12.1 million, respectively. The
corresponding amounts in 1995 were $72.4 million, $8.7 million, and $12.1
million, respectively.
 
Reinsurance ceded contracts do not relieve the Company from its obligations to
policyholders. The Company remains liable to its policyholders for the portion
reinsured to the extent that any reinsurer does not meet its obligations for
reinsurance ceded to it under the reinsurance agreements. Failure of the
reinsurers to honor their obligations could result in losses to the Company;
consequently, estimates are established for amounts deemed or estimated to be
uncollectible. To minimize its exposure to significant losses from reinsurance
insolvencies, the Company evaluates the financial condition of its reinsurers
and monitors concentration of credit risk arising from similar characteristics
of the reinsurer.

NOTE 7--REINSURANCE--CONTINUED
 
Neither the Company, nor any of its related parties, control, either directly
or indirectly, any external reinsurers with which the Company conducts
business. No policies issued by the Company have been reinsured with a foreign
company which is controlled, either directly or indirectly, by a party not
primarily engaged in the business of insurance.
 
The Company has not entered into any reinsurance agreements in which the
reinsurer may unilaterally cancel any reinsurance for reasons other than
nonpayment of premiums or other similar credits. The Company does not have any
reinsurance agreements in effect in which the amount of losses paid or accrued
through December 31, 1997 would result in a payment to the reinsurer of
amounts which, in the aggregate and allowing for offset of mutual credits from
other reinsurance agreements with the same reinsurer, exceed the total direct
premiums collected under the reinsured policies.
 
NOTE 8--FINANCIAL INSTRUMENTS WITH OFF-BALANCE-SHEET RISK
 
The Company utilizes a variety of off-balance sheet financial instruments as
part of its efforts to hedge and manage fluctuations in the market value of
its investment portfolio attributable to changes in general interest rate
levels and to manage duration mismatch of assets and liabilities. Those
instruments include swaps, caps, and future contracts.
 
The Company enters into interest rate swap contracts for the purpose of
converting the interest rate characteristics (fixed or variable) of certain
investments to match those of related insurance liabilities. Maturities of
current agreements range through 2011. These swaps involve, to varying
degrees, interest rate risk in excess of amounts recognized in the statement
of financial position.
 
The Company enters into interest rate cap contracts to manage exposure on
underlying security values due to a rise in interest rates. Maturities of
current agreements range through 2007.
 
The Company also uses financial futures contracts to hedge public bonds
intended for future sale in order to lock in the market value at the date of
contract. The Company is subject to the risks associated with changes in the
value of the underlying securities; however, such changes in value generally
are offset by changes in the value of the hedged items. The contract or
notional amounts of the contracts represent the extent of the Company's
involvement but not in the future cash requirements, as the Company intends to
close the open positions prior to settlement. Net deferred losses on financial
contracts were $2.8 million and $0.0 million at December 31, 1997 and 1996,
respectively.
 
The Company enters into currency rate swap agreements to manage exposure to
foreign exchange rate fluctuations. Maturities of current agreements range
through 2009. Should the counterparty fail to meet the terms of the contract,
the Company's market risk is limited to the currency rate differential.

</TABLE>
 
The Company's exposure to credit risk is the risk of loss from a counterparty
failing to perform according to the terms of the contract. The Company
continually monitors its positions and the credit ratings of the
counterparties to these financial instruments. To limit exposure associated
with counterparty nonperformance on interest rate and currency agreements, the
Company enters into master netting agreements with its counterparties. The
Company believes the risk of incurring losses due to nonperformance by its
counterparties is remote and that any such losses would not be material.
 
Based on the market rates in effect at December 31, 1997, the Company's
interest rate swaps, currency rate swaps and interest rate caps represented

NOTE 10--COMMITMENTS AND CONTINGENCIES--CONTINUED
 
In the normal course of its business operations, the Company is involved in
litigation from time to time with claimants, beneficiaries and others, and a
number of litigation matters were pending as of December 31, 1997. It is the
opinion of management, after consultation with counsel, that the ultimate
liability with respect to these claims, if any, will not materially affect the
financial position of the Company.

NOTE 12--IMPACT OF YEAR 2000 (UNAUDITED)
 
The Company relies on John Hancock, its parent company, for information
processing services. John Hancock has developed a plan to modify or replace
significant portions of its computer information and automated technologies so
that its systems, including those relied upon by the Company, will function
properly with respect to the dates in the year 2000 and thereafter. The
Company, along with John Hancock, presently believes that with modifications
to existing systems and conversions to new technologies, the year 2000 will
not pose significant operational problems for the computer systems upon which
the Company relies. However, if certain modifications and conversions are not
made, or are not completed timely, the year 2000 issue could have an adverse
impact on the operations of the Company.
 
John Hancock as early as 1994 had begun assessing, modifying and converting
the software related to its significant systems and has initiated formal
communications with significant business partners and customers to determine
the extent to which interface systems are vulnerable to those third parties'
failure to remediate their own year 2000 issues. While John Hancock is
developing alternative third party processing arrangements as it deems
appropriate, there is no guarantee that the systems of other companies on
which John Hancock's systems rely will be converted timely or will not have an
adverse effect on John Hancock's systems, including those upon which the
Company relies.

NOTE 12--IMPACT OF YEAR 2000 (UNAUDITED)--CONTINUED
 
John Hancock expects the project to be substantially complete by early 1999.
This completion target was derived utilizing numerous assumptions of future
events, including availability of certain resources and other factors.
However, there can be no guarantee that this completion target will be
achieved.

Post-Effective Amendment to Registrant's Registration Statement with the
Commission.
 
                                          Very truly yours,
