  We may offer additional variable investment options in the future.
<PAGE>
 
  For each variable investment option you select, we invest your money in the
corresponding "Fund" of the John Hancock Variable Series Trust I (the "Trust").
 The Trust is a so-called "series" type mutual fund registered with the
Securities and Exchange Commission ("SEC").  Each of the Trust's "Funds" is a
separately managed investment portfolio that has its own investment objective
and strategies.  Attached at the end of this prospectus is a prospectus for the
Trust that contains detailed information about each Fund.  Be sure to read the
prospectus for the Trust before selecting any variable investment option.
 
  For amounts you don't wish to invest in a variable investment option, you can
allocate to the fixed investment option.  We invest the assets allocated to the
fixed investment option in our general account and they earn interest at a fixed
rate, declared by us, subject to a 3% minimum.  Neither our general account nor
any interests in our general  account are registered with the SEC or subject to
the Federal securities laws.
 
  We refer to the variable investment options and the fixed investment option
together as "investment options."
 
  ************************************************************************
 
  The SEC has not approved or disapproved the contracts, or determined if this
prospectus is accurate or complete.  Any representation to the contrary is a
criminal offense.
 
  Contracts are not deposits or obligations of, or insured, endorsed, or
guaranteed by the U.S. Government, any bank, the Federal Deposit Insurance
Corporation, the Federal Reserve Board, or any other agency, entity or person,
other than John Hancock.  They involve investment risks including the possible
loss of principal.
 
  The contracts are not available in all states.  This prospectus does not
constitute an offer to sell, or a solicitation of an offer to buy, securities in
any state to any person to whom it is unlawful to make or solicit an offer in
that state.

                             GUIDE TO THIS PROSPECTUS
 
  This prospectus contains information that you should know before you buy a
contract or exercise any of your rights under the contract.  We have arranged
the prospectus in the following way:
 
     . The first section contains an "INDEX OF KEY WORDS."
 
     . Behind the index is the "FEE TABLE."  This section highlights the
       various fees and expenses you will pay directly or indirectly, if you
       purchase a contract.
 
     . The next section is called "BASIC INFORMATION."  It contains basic
       information about the contract presented in a question and answer
       format.  You should read the Basic Information before reading any
       other section of the prospectus.
 
     . Behind the Basic Information is "ADDITIONAL INFORMATION."  This
       section gives more details about the contract.  It generally does not
       repeat information contained in the Basic Information.
 
     . "CONDENSED FINANCIAL INFORMATION" follows the "Additional
       Information."  This gives some basic information about the size and
       past performance of the variable investment options.
 
 The Trust's prospectus is attached at the end of this prospectus.  You should
save these prospectuses for future reference.
 
                                IMPORTANT NOTICES
 
 This is the prospectus - it is not the contract.  The prospectus simplifies
many contract provisions to better communicate the contract's essential
features.  Your rights and obligations under the contract will be determined by
the language of the contract itself.  On request, we will provide the form of
contract for you to review.  In any event, when you receive your contract, we
suggest you read it promptly.
 
 We've also filed with the SEC a "Statement of Additional Information," dated
May 1, 1999.  This Statement contains detailed information not included in the
prospectus.  Although a separate document from this prospectus, the Statement
of Additional Information has the same legal effect as if it were a part of
this prospectus.  We will provide you with a free copy of the Statement upon
your request.  To give you an idea what's in the Statement, we have included a
copy of the Statement's table of contents on page __.

  The following fee table shows the various fees and expenses that you will pay,

  These annual contract expenses don't apply to amounts held in the fixed
investment options.
 
ANNUAL FUND EXPENSES (BASED ON % OF AVERAGE NET ASSETS)
 
 
  Each Fund  pays an investment management fee and other operating expenses.
These fees and expenses reduce the investment return of the Fund, and therefore,
indirectly reduce the return you will earn on any amounts you allocate to the
variable investment options that corresponds to that Fund. The figures in the
following chart are expressed as percentages of each Fund's average daily net
assets for 1998 (rounded to two decimal places). The percentages reflect the
investment management fees that were payable in 1998 and the 1998 other
operating expenses that would have been allocated to the Funds under the
allocation rules currently in effect:

 WHAT IS THE CONTRACT?
 
  The contract is a "deferred payment variable annuity contract."  An annuity
contract provides a person (known as the "annuitant" or "payee") with a series
of periodic payments. Because this contract is also a deferred payment contract,
the annuity payments will begin on a future date, called the contract's "date of
maturity." Under a variable annuity contract, the amount you have invested can
increase or decrease in value daily based upon the value of the variable
investment options chosen.
 
 WHO OWNS THE CONTRACT?
 
  That's up to you.  Unless the contract provides otherwise, the owner of the
contract is the person who can exercise the rights under the contract, such as
the right to choose the investment options or the right to surrender the
contract.  In many cases, the person buying the contract will be the owner.
 However, you are free to name another person or entity (such as a trust) as
owner.  In writing this prospectus, we've assumed that you, the reader, are the
person or persons entitled to exercise the rights and obligations under
discussion.
 
 IS THE OWNER ALSO THE ANNUITANT?
 
  Again, that's up to you.  The annuitant is the person upon whose death the
contract's death benefit becomes payable.  Also, the annuitant receives payments
from us under any annuity option that commences during the annuitant's lifetime.
 In many cases, the same person is both the annuitant and the owner of a
contract.  However, you are free to name another person as annuitant.
 
 HOW CAN I INVEST MONEY IN A CONTRACT?
 
PREMIUM PAYMENTS
 
  We call the investments you make in your contract "premiums" or "premium
payments."  You need at least a $1,000 initial premium payment to purchase a
contract.  Any subsequent scheduled premium payments must be at least $50.  If
you fail to make a specified premium payment when it's due, your contract will
nevertheless remain if force.
 
APPLYING FOR A CONTRACT
 
  An authorized representative of John Hancock through whom you purchase your
contract will assist you in (1) completing an application for a contract and (2)
transmitting it, along with your initial premium payment, to the John Hancock
Annuity Servicing Office.
 
  Once we receive your initial premium payment and all necessary information, we
will issue your contract and invest your initial premium payment within two
business days.  If the information is not in good order, we will contact you to
get the necessary information.  If for some reason, we are unable to complete
this process within 5 business days, we will either send back your money or get
your permission to keep it until we get all of the necessary information.
 
                                       9
 
<PAGE>
 
  We measure the years and anniversaries of your contract from its date of
issue.  We use the term "contract year" to refer to each period of time between
anniversaries of your contract's date of issue.
 
LIMITS ON PREMIUM PAYMENTS
 
  You can make premium payments of up to $500,000 in any one contract year
($100,000 into the fixed investment option, after the initial premium payment
which can be as much as $500,000).  The total of all new premium payments and
transfers that you allocate to any one variable investment option in any one
contract year may not exceed $500,000.  While the annuitant is alive and the
contract is in force, you can make premium payments at any time before the
annuitant's 85 1/2 birthday.
 
  We will not issue a contract if the proposed annuitant is age 85 or older.  We
may waive any of these limits, however.
 
WAYS TO MAKE PREMIUM PAYMENTS
 
  Premium payments made by check or money order must be:
 
     . drawn on a U.S. bank,
 
     . drawn in U.S. dollars, and
 
     . made payable to "John Hancock."
 
  Premium payments after the initial premium payment should be sent to the John
Hancock Annuity Servicing Office at one of the addresses shown on page 1 of this
prospectus. We will accept your initial premium payment by exchange from another
insurance company. You can find information about other methods of premium
payment by contacting your John Hancock representative or by contacting the John
Hancock Annuity Servicing Office.
 
  Once we have issued your contract and it becomes effective, we credit you with
any additional premiums you pay as of the day we receive them at the John
Hancock Annuity Servicing Office.
 
 HOW WILL THE VALUE OF MY INVESTMENT IN THE CONTRACT CHANGE OVER TIME?
 
  Prior to a contract's date of maturity, the amount you've invested in any
VARIABLE INVESTMENT OPTION will increase or decrease based upon the investment
experience of the corresponding Fund.  Except for certain charges we deduct,
your investment experience will be the same as if you had invested in the Fund
directly and reinvested all Fund dividends and distributions in additional
shares.
 
  Like a regular mutual fund, each Fund deducts investment  management fees and
other operating expenses.  These expenses are shown in the fee table on page __.
 However, unlike a
 
                                       10
 
<PAGE>
 
mutual fund, we will also deduct charges relating to the annuity guarantees and
other features provided by the contract.  These charges reduce your investment
performance and the amount we have credited to your contract in any variable
investment option.  We describe these charges under "What charges will be
deducted from my contract?" beginning on page __.
 
  Each premium payment you allocate to the fixed investment option will earn
interest (calculated on a compounded basis) at our declared rate in effect at
the time of the deposit into the fixed investment option.  From time to time, we
declare new rates, subject to a 3% minimum.  For purposes of crediting interest,
transfers from a variable investment option will be treated as a premium
payment.
 
  Under current practice, we credit interest to amounts allocated to the fixed
investment option based on the size of the initial premium payment,  We credit a
higher rate for initial premium payments of $10,000 or more.  The rate of
interest credited on each amount varies based upon when that amount was
allocated to the fixed investment option.
 
  At any time before the date of maturity, your "TOTAL VALUE OF YOUR CONTRACT"
equals
 
     . the total amount you invested,
 
     . minus all charges we deduct,
 
     . minus all withdrawals you have made,
 
     . plus or minus each variable investment option's positive or negative
       investment return that we credit daily to any of your contract's
       value daily while it is in that option, and
 
     . plus the interest we credit to any of your contract's value while it
       is in the fixed investment option.
 
 WHAT ANNUITY BENEFITS DOES A CONTRACT PROVIDE?
 
  If your contract is still in effect on its date of maturity, it enters what is
called the "annuity period".  During the annuity period, we make a series of
fixed or variable payments to you as provided under one of our several annuity
options.  The form in which we will make the annuity payments, and the
proportion of such payments that will be on a fixed basis and on a variable
basis, depend on the elections that you have in effect on the date of maturity.
 Therefore you should exercise care in selecting your date of maturity and your
choices that are in effect on that date.
 
  You should carefully review the discussion under "The annuity period,"
beginning on page __, for information about all of these choices you can make.
 
 WHAT ARE THE TAX CONSEQUENCES OF OWNING A CONTRACT?
 
                                       11
 
<PAGE>
 
  In most cases, no income tax will have to be paid on amounts you earn under a
contract until these earnings are paid out.  All or part of the following
distributions from a contract may constitute a taxable payout of earnings:
 
     . partial withdrawal
 
     . full withdrawal ("surrender")
 
     . payment of death benefit proceeds as a single sum upon you death or
       the annuitant's death
 
     . periodic payments under one of our annuity payment options
 
 How much you will be taxed on distribution is based upon complex tax rules and
depends on matters such as
 
     . the type of the distribution
 
     . when the distribution is made
 
     . the nature of any tax-qualified retirement plan for which the
       contract is being used
 
     . the circumstances under which the payments are made
 
  If your contract is issued in connection with a tax-qualified retirement plan,
all or part of your premium payments may be tax-deductible.
 
  Special 10% tax penalties apply in many cases to the taxable portion of any
distributions from a contract before you reach age 59 1/2. Also, most
tax-qualified plans require that distributions from a contract commence and/or
be completed by a certain period of time.  This effectively limits the period of
time during which you can continue to derive tax deferral benefits from any
tax-deductible premiums you paid or on any earnings under the contract.
 
 CAN I CHANGE MY CONTRACT'S INVESTMENT OPTIONS?
 
ALLOCATION OF PREMIUM PAYMENTS
 
  When you apply for your contract, you specify the investment options in which
your premium payments will be allocated.  You may change this investment
allocation for future premium payments at any time.  Any change in allocation
will be effective as of receipt of your request at the John Hancock Annuity
Servicing Office.
 
  At any one time, you may invest in up to 10 of the 24 investment options.
 Currently, you may use a maximum of 18 investment options over the life of your
contract.  For purposes of this limit, each contribution or transfer of assets
into an investment option that you are not then
 
                                       12
 
<PAGE>
 
using counts as one "use" of an investment option, even if you had used that
option at an earlier time.
 
TRANSFERRING YOUR ASSETS
 
  Up to 12 times during each year of your contract, you may transfer, free of
charge, all or part of the assets held in one investment option to any other
investment option.  We reserve the right to assess a charge of up to $25 for
transfer beyond the first 12 transfers per year.
 
  A number of restrictions apply to transfers in general.  You may NOT
 
     . transfer assets within 30 days prior to the contract's date of
       maturity,
 
     . transfer more than $500,000 in a contract year from any one variable
       investment option, without our prior approval,
 
     . make any transfer that would cause you to exceed the above-mentioned
       maximum of 18 investment options, or
 
     . make any transfer during the annuity period that would result in more
       than four investment options being used at once.
 
  In addition, certain restrictions apply specifically to transfers involving
the fixed investment option.  You may NOT
 
     . transfer assets to or from the fixed investment option during the
       annuity period,
 
     . transfer or deposit (exclusive of the initial premium payment) more
       than $100,000 into the fixed investment option during a contract
       year,
 
     . make any transfers into the fixed investment option within six months
       of a transfer out of the fixed investment option,
 
     . transfer out of the fixed investment option more than once during a
       contract year and only on or within 30 days after the anniversary of
       your contract's issuance ("contract anniversary"),
 
     . transfer or deposit money into the fixed investment option after the
       10th contact year, or
 
     . transfer out of the fixed investment option more than the greater of
       $500 or 20% of your assets in the fixed investment option in any one
       contract year.
 
PROCEDURE FOR TRANSFERRING YOUR ASSETS
 
                                       13
 
<PAGE>
 
  You may request a transfer in writing or, if you have authorized telephone
transfers, by telephone or fax.  All transfer requests should be directed to the
John Hancock Annuity Servicing Office at the one of the locations shown on page
1.  Your request should include
 
     . your name,
 
     . daytime telephone number,
 
     . contract number,
 
     . the names of the investment options being transferred to and from
       each, and
 
     . the amount of each transfer.
 
 The request becomes effective on the day we receive your request, in proper
form, at the John Hancock Annuity Servicing Office.
 
TELEPHONE TRANSFERS
 
  Once you have completed a written authorization, you may request a transfer by
telephone or by fax. If the fax request option becomes unavailable, another
means of telecommunication will be substituted.
 
  If you authorize telephone transactions, you will be liable for any loss,
expense or cost arising out of any unauthorized or fraudulent telephone
instructions which we reasonably believe to be genuine, unless such loss,
expense or cost is the result of our mistake or negligence. We employ procedures
which provide safeguards against the execution of unauthorized transactions, and
which are reasonably designed to confirm that instructions received by telephone
are genuine. These procedures include requiring personal identification, tape
recording calls, and providing written confirmation to the owner. If we do not
employ reasonable procedures to confirm that instructions communicated by
telephone are genuine, we may be liable for any loss due to unauthorized or
fraudulent instructions.
 
 WHAT FEES AND CHARGES WILL BE DEDUCTED FROM MY CONTRACT?
 
MORTALITY AND EXPENSE RISK CHARGE
 
  We deduct a daily charge that compensates us primarily for mortality and
expense risks that we assume under the contract.  On an annual basis, this
charge equals 0.90% of the value of the assets you have allocated to the
variable investment options.  (This charge does not apply to assets you have in
our fixed investment option.)
 
  In return for mortality risk charge, we assume the risk that annuitants as a
class will live longer than expected, requiring us to a pay greater number of
annuity payments.  In return for the expense risk charge, we assume the risk
that our expenses relating to the contracts may be
 
                                       14
 
<PAGE>
 
higher than we expected when we set the level of the contracts' other fees and
charges, or that our revenues from such other sources will be less.
 
ADMINISTRATIVE SERVICES CHARGE
 
  We deduct a daily charge for administrative and clerical services that the
contracts require us to provide.  On an annual basis, this charge equals 0.50%
of the value of the assets you have allocated to the variable investment
options.
 
ANNUAL CONTRACT FEE
 
  Prior to the date of maturity of your contract, we will deduct $30 each year
from your contract if it has a total value of less than $10,000.  We deduct this
annual contract fee at the beginning of each contract year after the first.  We
also deduct it if you surrender your contract.  We take the deduction
proportionally from each  investment option you are then using.  However, we
will not deduct any portion of the annual contract fee from the fixed investment
option if such deduction would result in an accumulation of amounts allocated to
the fixed investment option at less than the guaranteed minimum rate of 3%.  In
such case, we will deduct that portion of the contract fee proportionately from
the other investment options you are using.  We reserve the right to increase
the annual contract fee to $50.
 
PREMIUM TAXES
 
  We make deductions for any applicable premium or similar taxes based on the
amount of a premium payment.  Currently, certain states assess a tax of up to 5%
of each premium payment.
 
  In most cases, we deduct a charge in the amount of the tax from the total
value of the contract only at the time of annuitization, death, surrender, or
withdrawal.  We reserve the right, however, to deduct the charge from each
premium payment at the time it is made.  We compute the amount of the charge by
multiplying the applicable premium tax percentage times the amount you are
withdrawing, surrendering, annuitizing or applying to a death benefit.
 
WITHDRAWAL CHARGE
 
  If you withdraw some money from your contract prior to the date of maturity
("partial withdrawal") or if you surrender (turn in) your contract, in its
entirety, for cash prior to the date of maturity ("total withdrawal" or
"surrender"), we may assess a withdrawal charge.  We use this charge to help
defray expenses relating to the sales of the contracts, including commissions
paid and other distribution costs.
 
  Here's how we determine the charge:  In any contract year, you may withdraw up
  ----------------------------------
to 10% of the total value of your contract (computed as of the beginning of the
contract year) without the assessment of any withdrawal charge.  We refer to
this amount as the "free withdrawal amount."  However, if the amount you
withdraw or surrender totals more than the free withdrawal amount during the
contract year, we will assess a withdrawal charge on any amount
 
                                       15
 
<PAGE>
 
of the excess that we attribute to premium payments you made within seven years
of the date of the withdrawal or surrender.
 
  The withdrawal charge percentage depends upon the number of years that have
elapsed from the date you paid the premium to the date of its withdrawal, as
follows:
 
<TABLE>
<CAPTION>

   DATE OF SURRENDER OR WITHDRAWAL       WITHDRAWAL CHARGE*

</TABLE>
 
 
  * AS A PERCENTAGE OF THE AMOUNT OF SUCH PREMIUM THAT WE CONSIDER TO HAVE
    BEEN WITHDRAWN (INCLUDING THE WITHDRAWAL CHARGE), AS EXPLAINED IN THE TEXT
    IMMEDIATELY BELOW.
 
  Solely for purposes of determining the amount of the withdrawal charge, we
assume that each withdrawal (together with any associated withdrawal charge) is
a withdrawal first from the earliest premium payment, and then from the next
earliest premium payment, and so forth until all payments have been exhausted.
Once a premium payment has been considered to have been "withdrawn" under these
procedures, that premium payment will not enter into any future withdrawal
charge calculations.  For this purpose, we also consider any amounts that we
deduct for the annual contract charge to have been withdrawals of premium
payments (which means that no withdrawal charge will ever be paid on those
amounts).
 
  The amount of any withdrawal that exceeds any remaining premium payments that
have not already been considered as withdrawn will not be subject to any
withdrawal charge.  This means that no withdrawal charge will apply to any
favorable investment experience that you have earned.
 
  Here's how we deduct the withdrawal charge:  We deduct the withdrawal charge
  ------------------------------------------
proportionally from each investment option being reduced by the surrender or
withdrawal.  For example, if 60% of the withdrawal amount comes from the Growth
& Income option and 40% from the Money Market option, then we will deduct 60% of
the withdrawal charge from the Growth & Income option and 40% from the Money
Market option.  If any such option has insufficient remaining value to cover the
charge, we will deduct any shortfall from all of your other investment options,
pro-rata based on the value in each.  If your contract as a whole has
insufficient surrender value to pay the entire charge, we will pay you no more
than the surrender value.
 
  You will find examples of how we compute the withdrawal charge in Appendix A
to this prospectus.
 
  When withdrawal charges don't apply:  We don't assess a withdrawal charge in
  -----------------------------------
the following situations:
 
                                       16
 
<PAGE>
 
     . on amounts applied to an annuity option at the contract's date of
       maturity or to pay a death benefit; or
 
     . on amounts withdrawn to satisfy the minimum distribution requirements
       for tax-qualified plans.  (Amounts above the minimum distribution
       requirements are subject to any applicable withdrawal charge,
       however.)
 
  In addition, under our exchange offer program, certain pension plans may be
eligible to exchange their contracts, without charge, for shares of certain
mutual funds distributed by John Hancock Funds, Inc.  Under the terms of the
exchange offer, any remaining withdrawal charge applicable to any contract
exchanged would be waived at the time of the exchange transaction.  You can
participate in the exchange offer only if your contract was purchased on behalf
either
 
     . a pension plan qualified under Section 401(k) of the Internal Revenue
       Code of 1986 or
 
     . a targeted benefit pension plan where plan assets are not allocated
       specifically as being for the account of individual plan
       participants.
 
   The exchange offer was expected to remain open until March 1, 1999, but could
be extended for particular offerees under special circumstances.  Such
extensions have occurred and may continue to occur for an indefinite period of
time.
 
 HOW CAN I WITHDRAW MONEY FROM MY CONTRACT?
 
SURRENDERS AND PARTIAL WITHDRAWALS
 
  Prior to your contract's date of maturity, if the annuitant is living, you
may:
 
     . surrender your contract for a cash payment of its "surrender value,"
       or
 
     . make a partial withdrawal of the surrender value.
 
  The "surrender value" of a contract is the total value of a contract, MINUS
the annual contract fee and any applicable premium tax and withdrawal charges.
 We will determine the amount surrendered or withdrawn as of the date we receive
your request at the John Hancock Annuity Servicing Office.
 
  Certain surrenders and withdrawals may result in taxable income to you or
other tax consequences as described under "Tax information," beginning on page
__.  Among other things, if you make a full surrender or partial withdrawal from
your contract before you reach age 59 1/2, an additional federal penalty of 10%
generally applies to any taxable portion of the withdrawal.
 
  We will deduct any partial withdrawal proportionally from each of your
investment options based on the value in each, unless you direct otherwise.
 
                                       17
 
<PAGE>
 
  Without our prior approval, you may not make a partial withdrawal
 
     . for an amount less than $50, or
 
     . if the remaining total value of your contract would be less than
       $1,000.
 
 If your "free withdrawal value" at any time is less than $100, you must
withdraw that amount in full, in a single sum, before you make any other partial
withdrawals.  A partial withdrawal is not a loan and cannot be repaid.  We
reserve the right to terminate your contract if the value of your contract
becomes zero.
 
  You generally may not make any surrenders or partial withdrawals once we begin
making payments under an annuity option.
 
 WHAT HAPPENS IF THE ANNUITANT DIES BEFORE MY CONTRACT'S DATE OF MATURITY?
 
GUARANTEED MINIMUM DEATH BENEFIT
 
  If the annuitant dies before your contract's date of maturity, we will pay a
death benefit.  If the death occurs before the contract anniversary nearest the
annuitant's 75th birthday, we will pay the greater of:
 
     . the total value of your contract, or
 
     . the total amount of premium payments made, minus any partial
       withdrawals and related withdrawal charges.
 
 If the death occurs on or after the contract anniversary nearest the
annuitant's 75th birthday, we will pay an amount equal to the total value of
your contract.
 
  We calculate the death benefit as of the day we receive, at the John Hancock
Annuity Servicing Office:
 
     . proof of the annuitant's death, and
 
     . any required instructions as to method of settlement.
 
  Unless you have elected an optional method of settlement, we will pay the
death benefit in a single sum to the beneficiary you chose prior to the
annuitant's death.  If you have not elected an optional method of settlement,
the beneficiary may do so.  However, if the death benefit is less than $5,000,
we will pay it in a lump sum, regardless of any election.  You can find more
information about optional methods of settlement under "Annuity options,"
beginning on page __.
 
 CAN I RETURN MY CONTRACT?
 
                                       18
 
<PAGE>
 
  In most cases, you may return your contract for any reason within 10 days
after you receive it.  If you do, we will pay you the total value of your
contract, plus the amount of premium taxes that we have deducted.  However,
there are some exceptions to this general rule:
 
     . if you return a contract issued in Hawaii, Idaho, Missouri, Nebraska,
       North Carolina, Oklahoma, Oregon, South Carolina, Washington, West
       Virginia, or Utah, you will receive the gross premiums you paid.
 
     . if you return a contract that is an individual retirement annuity
       ("IRA"), you will receive the gross premiums you paid.
 
     . if your contract was issued in California after your 60/th/ birthday,
       you may return the contract within 30 days and receive the gross
       premiums you paid.
 
     . if your contract was issued in North Dakota, you may return it within
       20 days and receive the gross premiums you paid.

 DESCRIPTION OF JOHN HANCOCK
 
  We are John Hancock, a mutual life insurance company organized, in 1862, under
the laws of the Commonwealth of Massachusetts.  Our home office is located at
200 Clarendon Street, Boston, Massachusetts  02117.  We have authority to
transact business in all 50 states.  As of December 31, 1998, we had more that
$67.1 billion of assets.
 
 WHO SHOULD PURCHASE A CONTRACT?
 
  We designed these contracts for individuals doing their own retirement
planning, including purchases under plans and trusts that do not qualify for
special tax treatment under the Internal Revenue Code of 1986 (the "Code").  We
also designed the contracts for purchase under:
 
     . pension and profit-sharing plans qualified under Section 401(c) of
       the Code, known as H.R. 10 Plans;
 
     . pension or profit-sharing plans qualified under sections 401(a) or
       403(a) of the Code, known as "corporate plans";
 
     . annuity purchase plans adopted under Section 403(b) of the Code by
       public school systems and certain other tax-exempt organizations;
        and
 
     . individual retirement annuity ("IRA") plans satisfying the
       requirements of Section 408 of the Code.
 
     . deferred compensation plans maintained by a state or political
       subdivision under Section 457 of the Code
 
  When a contract forms part of a tax-qualified plan it becomes subject to
special tax law requirements, as well as the terms of the plan documents
themselves, if any.  Also, in some cases, certain requirements under "ERISA"
(the Employee Retirement Income Security Act of 1974) may apply.  Requirements
from any of these sources may, in effect, take precedence over (and in that
sense modify) the rights and privileges that an owner otherwise would have under
a contract.  Some such requirements may also apply to certain retirement plans
that are not tax-qualified.
 
  We may include certain requirements from the above sources in endorsements or
riders to the affected contracts.  In other cases, we do not.  In no event,
however, do we undertake to assure a contract's compliance with all plan, tax
law, and ERISA requirements applicable to a tax-qualified or non tax-qualified
retirement plan.  Therefore, if you use or plan to use a contract in connection
with such a plan, you must consult with competent legal and tax advisers to
ensure that you know of (and comply with) all such requirements that apply in
your circumstances.
 
  To accommodate "employer-related" plans, we provide "unisex" purchase rates.
 That means the annuity purchase rates are the same for males and females.  Any
questions you have as to whether you are participating in an "employer-related"
plan should be directed to your employer.  Any question you or your employer
have about unisex rates may be directed to the John Hancock Annuity Servicing
Office.
 
 HOW WE SUPPORT THE VARIABLE INVESTMENT OPTIONS
 
  We hold the Fund shares that support our variable investment options in John
Hancock Variable Annuity Account U (the "Account"), a separate account
established by John Hancock under Massachusetts law.  The Account is registered
as a unit investment trust under the Investment Company Act of 1940 ("1940
Act").
 
  The Account's assets, including the Trust's shares, belong to John Hancock.
 Each contract
 
                                       21
 
<PAGE>
 
provides that amounts we hold in the Account pursuant to the policies cannot be
reached by any other persons who may have claims against us.
 
  All of John Hancock's general assets also support John Hancock's obligations
under the contracts, as well as all of its other obligations and liabilities.
 These general assets consist of all John Hancock's assets that are not held in
the Account (or in another separate account) under variable annuity or variable
life insurance contracts that give their owners a preferred claim on those
assets.
 
 THE ACCUMULATION PERIOD
 
YOUR VALUE IN OUR VARIABLE INVESTMENT OPTIONS
 
  Each premium payment or transfer that you allocate to a variable investment
option purchases "accumulation units" of that variable investment option.
 Similarly, each withdrawal or transfer that you take from a variable investment
option (as well as certain charges that may be allocated to that option) result
in a cancellation of such accumulation units.
 
VALUATION OF ACCUMULATION UNITS
 
  To determine the number of accumulation units that a specific transaction will
purchase or cancel, we use the following formula:
 
dollar amount of transaction
                   DIVIDED BY
value of one accumulation unit for the applicable
variable investment option at the time of such
transaction
- -------------------------------------------------
 
 
  The value of each accumulation unit will change daily depending upon the
investment performance of the Fund that corresponds to that variable investment
option and certain charges we deduct from such investment option. (See below
under "Variable investment option valuation procedures.")
 
  Therefore, at any time prior to the date of maturity, the total value of your
contract in a variable investment option can be computed according to the
following formula:
 
number of accumulation units in the variable
investment options
                    TIMES
value of one accumulation unit for the
applicable variable investment option that
time
- ---------------------------------------------
 
 
YOUR VALUE IN THE FIXED INVESTMENT OPTION
 
  On any date, the total value of your contract in the fixed investment option
equals:
 
     . the amount of premium payments or transferred amounts allocated to
       the fixed investment option, MINUS
 
     . the amount of any withdrawals or transfers paid out of the fixed
       investment option, PLUS
 
     . interest compounded daily on any amounts in the fixed investment
       option at the effective annual rate of interest we have declared,
       MINUS
 
     . the amount of any charges and fees deducted from fixed investment
       option.
 
 THE ANNUITY PERIOD
 
DATE OF MATURITY
 
  Your contract specifies the date of maturity, when payments from one of our
annuity options are scheduled to begin.  You initially choose a date of maturity
when you complete your application for a contract.  Unless we otherwise permit,
the date of maturity must be
 
     . at least 6 months after the date the first premium payment is applied
       to your contract and
 
                                       22
 
<PAGE>
 
     . no later than the maximum age specified in your contract.
 
  Subject always to these requirements, you may subsequently select an earlier
date of maturity.  The John Hancock Annuity Servicing Office must receive your
new selection at least 31 days prior to the new date of maturity, however.
 Also, if you are selecting or changing your date of maturity for a contract
issued under a tax-qualified plan, special limits apply.  (See "Contracts
purchased for a tax-qualified plan," beginning on page __.)  If you purchased
your contract in Washington,  you cannot changed the date of maturity.
 
CHOOSING FIXED OR VARIABLE ANNUITY PAYMENTS
 
  During the annuity period, the total value of your contract must be allocated
to no more than four investment options.  During the annuity period, we offer
annuity payments on a fixed  basis as one investment option, and annuity
payments on a variable basis for EACH variable investment option.
 
  We will generally apply (1) amounts allocated to the fixed investment option
as of the date of maturity to provide annuity payments on a fixed basis and (2)
amounts allocated to variable investment options to provide annuity payments on
a variable basis.  If you are using more than four investment options on the
date of maturity, we will divide your contract's value among the four investment
options with the largest values, pro-rata based on the amount of the total value
of your contract that you have in each.
 
  Once annuity payments commence, you may not make transfers from fixed to
variable or from variable to fixed.
 
SELECTING AN ANNUITY OPTION
 
  Each contract provides, at the time of its issuance, for annuity payments to
commence on the date of maturity pursuant to Option A:  "life annuity with 10
years guaranteed" (discussed under "Annuity options" on page __ below).
 
  Prior to the date of maturity, you may select a different annuity option.
 However, if the total value of your contract on the date of maturity is not at
least $5,000, Option A:  "life annuity with 10 years guaranteed" will apply,
regardless of any other election that you have made.  You may not change the
form of annuity option once payments commence.
 
  If the initial monthly payment under an annuity option would be less than $50,
we may make a single sum payment equal to the total surrender value of your
contract on the date the initial payment would be payable.  Such single payment
would replace all other benefits.  Alternatively, if you agree, we will make
payments at quarterly, semi-annual, or annual intervals in place of monthly
payments.
 
  Subject to that $50 minimum limitation, your beneficiary may elect an annuity
option if
 
     . you have not made an election prior to the annuitant's death;
 
     . the beneficiary is entitled to payment of a death benefit of at least
       $5,000 in a single sum; and
 
     . the beneficiary notifies us of the election prior to the date the
       proceeds become payable.
 
    If the total value of your contract, at death or surrender, is less than
$5,000, no annuity option will be available.
 
VARIABLE MONTHLY ANNUITY PAYMENTS
 
  We determine the amount of the first variable monthly payment under any
variable investment option by using the applicable annuity purchase rate for the
annuity option under which the payment will be made.  The contract sets forth
these annuity purchase rates.  In most cases they vary by the age and gender of
the annuitant or other payee.
 
                                       23
 
<PAGE>
 
  The amount of each subsequent variable annuity payment under that variable
investment option depends upon the investment performance of that variable
investment option.  Here's how it works:
 
     . we calculate the actual net investment return of the variable
       investment option (after deducting all charges) during the period
       between the dates for determining the current and immediately
       previous monthly payments.
 
     . if that actual net investment return exceeds the "assumed investment
       rate" (explained below), the current monthly payment will be larger
       than the previous one.
 
     . if the actual net investment return is less than the assumed
       investment rate, the current monthly payment will be smaller than the
       previous one.
 
   ASSUMED INVESTMENT RATE
   -----------------------
 
  The assumed investment rate for any variable portion of your annuity payments
will be 3 1/2 % per year, except as follows.
 
  You may elect an assumed investment rate of 5% or 6%, provided such a rate is
available in your state.  If you elect a higher assumed investment rate, your
initial variable annuity payment will also be higher.  Eventually, however, the
monthly variable annuity payments may be smaller than if you had elected a lower
assumed investment rate.
 
FIXED MONTHLY ANNUITY PAYMENTS
 
  The dollar amount of each fixed monthly annuity payment is specified during
the entire period of annuity payments, according to the provisions of the
annuity option selected.  To determine such dollar amount we first, in
accordance with the procedures described above, calculate the amount to be
applied to the fixed annuity option as of the date of maturity.  We then
subtract any applicable premium tax charge and divide the difference by $1,000.
 We then multiply the result by the greater of
 
     . the applicable fixed annuity purchase rate shown in the appropriate
       table in the contract; or
 
     . the rate we currently offer at the time of annuitization.  (This
       current rate may be based on the sex of the annuitant, unless
       prohibited by law.)
 
ANNUITY OPTIONS
 
  Two basic annuity options are available:
 
  OPTION A:  LIFE ANNUITY WITH PAYMENTS FOR A GUARANTEED PERIOD - We will make
monthly payments for a guaranteed period of 5, 10, or 20 years, as selected by
you or your beneficiary, and after such period for as long as the payee lives.
 If the payee dies prior to the end of such guaranteed period, we will continue
payments for the remainder of the guarantee period to a contingent payee,
subject to the terms of any supplemental agreement issued.
 
  Federal income tax requirements currently applicable to contracts used with
H.R. 10 plans and individual retirement annuities 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.
 
  OPTION B:  LIFE ANNUITY WITHOUT FURTHER PAYMENT ON DEATH OF PAYEE - We will
make monthly payments to the payee as long as he or she lives.  We guarantee no
minimum number of payments.
 
 VARIABLE INVESTMENT OPTION VALUATION PROCEDURES
 
  We compute the net investment return and accumulation unit values for each
variable investment option as of the end of each business day.
 
                                       24
 
<PAGE>
 
A business day is any date on which the New York Stock Exchange is open for
regular trading.  Each business day ends at the close of regular trading for the
day on that exchange.  Usually this is 4:00 p.m., Eastern time.  On any date
other than a business day, the accumulation unit value or annuity unit value
will be the same as the value at the close of the next following business day.
 
 DISTRIBUTION REQUIREMENTS FOLLOWING DEATH OF OWNER
 
  If you did not purchase your contract under a tax-qualified plan (as that term
is used below), the Code requires that the following distribution provisions
apply if you die.  We summarize these provisions in the box below.  In most
cases, these provisions do not cause a problem if you are also the annuitant
under your policy.  If you have designated someone other than yourself as the
annuitant, however, your heirs will have less discretion than you would have had
in determining when and how the contract's value would be paid out.
 
 IF YOU DIE BEFORE ANNUITY PAYMENTS HAVE BEGUN:
     .if the contract's designated beneficiary is your
       surviving spouse, your spouse may continue the contract
       in force as the owner.
     .if the beneficiary is not your surviving spouse OR if
       the beneficiary is your surviving spouse but chooses not
       to continue the contract, the entire interest (as
       discussed below) in the contract on the date of your
       death must be:
     (1) paid out in full within five years of your death or
     (2)
       applied in full towards the purchase of a life annuity
       on the beneficiary with payments commencing within one
       year of your death
  If you are the annuitant, as well as the owner, the entire
interest in the contract on the date of your death equals the death
benefit that then becomes payable.  If you are the owner but not
the annuitant, the entire interest equals
     .the surrender value if paid out in full within five
       years of your death, or
     .
       the total value of your contract applied in full towards
       the purchase of a life annuity on the beneficiary with
       payments commencing within one year of your death.
 IF YOU DIE ON OR AFTER ANNUITY PAYMENTS HAVE BEGUN
     .any remaining amount that we owe must be paid out at

- -------------------------------------------------------------------
 
 
  Notice of the death of an owner or annuitant should be furnished promptly to
the John Hancock Annuity Servicing Office.
 
  The Code imposes very similar distribution requirements on contracts used to
fund tax-qualified plans.  We provide the required provisions for tax-qualified
plans in separate disclosures and endorsements.
 
 MISCELLANEOUS PROVISIONS
 
ASSIGNMENT; CHANGE OF OWNER OR BENEFICIARY
 
  To qualify for favorable tax treatment, certain contracts can't be sold;
 assigned;  discounted;  or
 
                                       25
 
<PAGE>
 
pledged as collateral for a loan, as security for the performance of an
obligation, or for any other purpose, unless the owner is a trustee under
section 401(a) of the Internal Revenue Code.
 
  Subject to these limits, while the annuitant is alive, you may designate
someone else as the owner by written notice to the John Hancock Annuity
Servicing Office.  The contract designates the person you choose as beneficiary.
 You may change the beneficiary by written notice no later than receipt of due
proof of the death of the annuitant.  Changes of owner or beneficiary will take
effect whether or not you or the annuitant is then alive.  However, these
changes are subject to:
 
     . the rights of any assignees of record,
 
     . the any action taken prior to receipt of the notice, and
 
     . certain other conditions.
 
  An assignment, pledge, or other transfer may be a taxable event.  See "Tax
information" below.  Therefore, you should consult a competent tax adviser
before taking any such action.
 
 TAX INFORMATION
 
OUR INCOME TAXES
 
  We are taxed as a life insurance company under the Internal Revenue Code (the
"Code").  The Account is taxed as part of our operations and is not taxed
separately.
 
  The contracts permit us to deduct a charge for any taxes we incur that are
attributable to the operation or existence of the contracts or the Account.
 Currently, we do not anticipate making a charge such taxes.  If the level of
the current taxes increases, however, or is expected to increase in the future,
we reserve the right to make a charge in the future.
 
CONTRACTS NOT PURCHASED TO FUND A TAX-QUALIFIED PLAN
 
   UNDISTRIBUTED GAINS
   -------------------
 
  We believe the contracts will be considered annuity contracts under Section 72
of the Code.  This means that, ordinarily, you pay no federal income tax on any
gains in your contract until we actually distribute assets to you.
 
  However, a contract owned other than by a natural person does not generally
qualify as an annuity for tax purposes.  Any increase in value therefore would
constitute ordinary taxable income to such an owner in the year earned.
 
   ANNUITY PAYMENTS
   ----------------
 
  When we make payments under a contract in the form of an annuity, each payment
will result in taxable ordinary income to the payee, to the extent that each
such payment exceeds an allocable portion of your "investment in the contract"
(as defined in the Code).  In general, your "investment in the contract" equals
the aggregate amount of premium payments you have made over the life of the
contract, reduced by any amounts previously distributed from the contract that
were not subject to tax.
 
  The Code prescribes the allocable portion of each such annuity payment to be
excluded from income according to one formula if the payments are variable and a
somewhat different formula if the payments are fixed.  In each case, speaking
generally, the formula seeks to allocate an appropriate amount of the investment
in the contract to each payment.  After the entire "investment in the contract"
has been distributed, any remaining payment is fully taxable.
 
   SURRENDERS AND WITHDRAWALS BEFORE DATE OF MATURITY
   --------------------------------------------------
 
  When we make a single sum payment from a contract, you have ordinary taxable
income, to the extent the payment exceeds your "investment in the contract"
(discussed above).  Such a single sum
 
                                       26
 
<PAGE>
 
payment can occur, for example, if you surrender your contract or if no annuity
payment option is selected for a death benefit payment.
 
  When you take a partial withdrawal from a contract, all or part of the payment
may constitute taxable ordinary income to you.  The taxable portion generally
equals the amount, if any, by which the payment exceeds your then investment in
the contract.  If you assign or pledge any part your contract's value, the value
so pledged or assigned is taxed the same way as if it were a partial withdrawal.
 
  For purposes of determining the amount of taxable income resulting from a
single sum payment or a partial withdrawal, all annuity contracts issued by John
Hancock or its affiliates to the owner within the same calendar year will be
treated as if they were a single contract.
 
   PENALTY FOR PREMATURE WITHDRAWALS
   ---------------------------------
 
  The taxable portion of any withdrawal or single sum payment may also trigger
an additional 10% penalty tax.  The penalty tax does not apply to payments made
to you after age 59 1/2, or on account of your death or disability.  Nor will it
apply to withdrawals in substantially equal periodic payments over the life of
the payee (or over the joint lives of the payee and the payee's beneficiary).
 
DIVERSIFICATION REQUIREMENTS
 
  Each of the Funds of the Trust intends to qualify as a regulated investment
company under Subchapter M of the Code and meet the investment diversification
tests of Section 817(h) of the Code and the underlying regulations.  Failure to
do so could result in current taxation to you on gains in your contract for the
year in which such failure occurred and thereafter.
 
  The Treasury Department or the Internal Revenue Service may, at some future
time, issue a ruling or regulation presenting situations in which it will deem
contract owners to exercise "investor control" over the Fund shares that are
attributable to their contracts.  The Treasury Department has said informally
that this could limit the number or frequency of transfers among variable
investment options.  This could cause you to be taxed as if you were the direct
owner of your allocable portion of Fund shares.  We reserve the right to amend
the contracts or the choice of investment options to avoid, if possible, current
taxation to the owners.
 
CONTRACTS PURCHASED FOR A TAX-QUALIFIED PLAN
 
  We have no responsibility for determining whether a particular retirement plan
satisfies the applicable requirements of the Code or whether a particular
employee is eligible for inclusion under a plan.
 
   WITHHOLDING ON ROLLOVER DISTRIBUTIONS
   -------------------------------------
 
  The tax law requires us to withhold 20% from certain distributions from
tax-qualified plans. We do not have to make the withholding, however, if you
rollover your entire distribution to another plan and you request us to pay it
directly to the successor plan.  Otherwise, the 20% mandatory withholding will
reduce the amount you can rollover to the new plan, unless you add funds to the
rollover from other sources.  Consult a qualified tax adviser before making such
a distribution.
 
   CONTRACTS PURCHASED AS INDIVIDUAL RETIREMENT ANNUITIES (IRAS)
   -------------------------------------------------------------
 
  An individual retirement annuity (as defined in Section 408 of the Code)
generally permits an eligible purchaser to take a federal income tax deduction
of up to $2,000 per year for contributions to the IRA.  (You can never, however,
deduct more than 100% of your compensation includable in your gross income for
the year.)  You may also purchase an IRA contract for the benefit of your spouse
(regardless of whether your spouse has a paying job).  You can generally deduct
up to $2,000 for each of you and your spouse (or, if less, your combined
compensation).
 
                                       27
 
<PAGE>
 
  If you or your spouse is an active participant in an employer-sponsored
retirement plan, you may make deductible premium payment only if your adjusted
gross incomes do not exceed certain amounts.  You can still contribute the full
$2000 for each of you and your spouse, however, even though they are not
deductible.  Nor can you take a deduction for premium payments made in or after
the taxable year in which you attain age 70 1/2 or for a "rollover contribution"
as defined in the Code.
 
  If you have made any non-deductible contributions to an IRA contract, all or
part of any withdrawal or surrender proceeds, single sum death benefit or any
annuity payment, may be excluded from your taxable income when you receive the
proceeds.  In general, all other amounts paid out from an IRA contract (in the
form of an annuity, a single sum, or partial withdrawal), are taxable to the
payee as ordinary income.  As in the case of a contract not purchased under a
tax-qualified plan, you may incur additional adverse tax consequences, if you
make a surrender or withdrawal before you reach age 59 1/2 (unless certain
exceptions apply similar to those described above for such non-qualified
contracts).
 
  The tax law requires that annuity payments under an IRA contract begin no
later than April 1 of the year following the year in which the owner attains age
70 1/2.
 
   CONTRACTS PURCHASED UNDER SIMPLE RETIREMENT ACCOUNTS (SIMPLE IRAS)
   ------------------------------------------------------------------
 
  In general, a small business employer may establish a SIMPLE IRA retirement
plan, if the employer employed less than 100 employees on any day during the
preceding calendar year.  As an employee of such small business employer, you
may make premium payments to the SIMPLE IRA.  You may specify the percentage of
compensation that you will contribute to the SIMPLE IRA, provided the amount of
contribution does not exceed $6,000 a year.  Your employer must elect to make a
matching contribution of up to 3% of your compensation or an non-elective
contribution equal to 2% of your compensation.
 
   CONTRACTS PURCHASED UNDER CERTAIN NON-DEDUCTIBLE IRAS (ROTH IRAS)
   -----------------------------------------------------------------
 
  In general, you may make purchase payments of up to $2,000 each year for a new
type of non-deductible IRA contract, known as a ROTH IRA. Any contributions made
during the year for any other IRA you have will reduce the amount you otherwise
could contribution to a ROTH IRA.  Also, the $2000 maximum for a ROTH IRA phases
out for single taxpayers with adjusted gross incomes between $95,000 and
$110,000, for married taxpayers filing jointly with adjusted gross incomes
between $150,000 and $160,000, and for a married taxpayer filing separately with
adjusted gross income between $0 and $15,000.
 
  If you hold your ROTH IRA for at least five years the payee will not owe any
federal income taxes or early withdrawal penalties on amounts paid out from the
contract
 
     . after you reach age 591/2,
 
     . on your death or disability, or
 
     . to one of the following qualified first-time home purchasers, subject
       to a $10,000 lifetime maximum:  you or your spouse, child,
       grandchild, or ancestor.
 
  The Code treats payments you receive from a ROTH IRA that do not qualify for
the above tax free treatment as a return of the contributions you made first.
 However, any amount of such non-qualifying payments or distributions that
exceed the amount of your contributions is taxable to you as ordinary income and
possibly subject to the 10% penalty tax.
 
  You may make a tax-free rollover contribution from a non-ROTH IRA, unless
 
                                       28
 
<PAGE>
 
     . you have adjusted gross income over $100,000 or
 
     . you are a married taxpayer filing a separate return.
 
 The $2,000 ROTH IRA contribution limit does not apply to tax-free rollover
contributions.
 
  You must, however, pay tax on any portion of the non-ROTH IRA being rolled
over that represents income on a previously deductible IRA contribution.  No
similar limitations apply to rollovers from one ROTH IRA to another ROTH IRA.
 
   CONTRACTS PURCHASED UNDER SECTION 403(B) PLANS (TSA)
   ----------------------------------------------------
 
  Under these tax-sheltered annuity ("TSA") arrangements, public school systems
and certain tax-exempt organizations can make premium payments into a contracts
owned by their employees that are not taxable currently to the employee.
 
  The amount of such non-taxable contributions each year
 
     . is limited by a maximum (called the "exclusion allowance") that is
       computed in accordance with a formula prescribed under the Code;
 
     . may not, together with all other deferrals the employee elects under
       other tax-qualified plans, exceed $10,000; and
 
     . is subject to certain other limits (described in Section 415 of the
       Code).
 
  When we make annuity payments from the contract, such payments are taxed to
the employee or other payee under the same rules that apply to such payments
under corporate plans (discussed below), except that five-year averaging and
capital gain phase-out are not available.
 
  When we make payments from a TSA contract on surrender of the contract,
partial withdrawal, death of the annuitant, or commencement of an annuity
option, the payee ordinarily must treat the entire payment as ordinary taxable
income.
 
  Moreover, the Code prohibits distributions from a TSA contract before the
employee reaches age 59 1/2, except
 
     . on the employee's separation from service, death, or disability,
 
     . with respect to distributions of assets held under a TSA contract as
       of December 31, 1988,
 
     . transfers and exchanges to other products that qualify under Section
       403(b).
 
   CONTRACTS PURCHASED FOR "CORPORATE" PLANS
   -----------------------------------------
 
  In general, an employer may deduct from its taxable income premium payments it
makes under
 
     . a qualified pension or profit-sharing plan described in Section
       401(a) of the Code or
 
     . a qualified annuity plan described in Section 403(a) of the Code.
 
 Nor do the employees participating in the plan have to pay tax on such
contributions when made.
 
  Annuity payments (or other payments, such as upon withdrawal, death or
surrender) generally constitute taxable income to the payee; and the payee must
pay income tax on the amount by which a payment exceeds its allocable share of
 the employee's "investment in the contract" (as defined in the Code), if any.
 In general, an employee's
 
                                       29
 
<PAGE>
 
"investment in the contract" equals the aggregate amount of premium payments
made by the employee.
 
  The non-taxable portion of each annuity payment is determined, under the Code,
according to one formula if the payments are variable and a somewhat different
formula if the payments are fixed.  In each case, speaking generally, the
formula seeks to allocate an appropriate amount of the investment in the
contract to each payment.
 
  Certain special five-year income tax averaging provisions are available for
total distributions made in 1999, but not after that.  Other favorable
procedures may also be available to taxpayers who had attained age 50 prior to
January 1, 1986.
 
  IRS required minimum distributions to the employee must begin no later than
April 1 of the year following the year in which the employee reaches age 70 1/2
or, if later, retires.
 
   CONTRACTS PURCHASED FOR H.R. 10 (SELF-EMPLOYED) PLANS
   -----------------------------------------------------
 
  Self-employed persons, including partnerships, purchase contracts for
tax-qualified pension and profit-sharing plans that they establish for
themselves and for their employees.  The Code limits the maximum amount of
premium payments that the self-employed person may deduct for federal income tax
purposes each year.  With respect to variable annuity contracts issued on the
life of self-employed persons under such plans, the maximum generally is the
lesser of
 
     . $30,000, or
 
     . 25% of "earned income" (as defined in the Code).
 
  Self-employed persons must also make premium payments for their employees (who
have met certain eligibility requirements) at least at the same rate as they do
for themselves.
 
  tax-qualified plans may permit self-employed persons and their employees to
make additional premium payments themselves (which are not deductible) of up to
10% of earned income or compensation.
 
  When we make annuity payments under an H.R. 10 contract, the payee must pay
federal income taxes under the same rules that apply to such payments under
corporate plans (discussed above).
 
  The tax treatment of annuity payments is also the same as under corporate
plans (discussed above); as, in most respects, is the tax treatment of single
sum payments.
 
  The same rules discussed above that determine n for corporate plans (a) when
annuity payments must commence and (b) the 10% penalty tax on certain early
distributions also apply to H.R. 10 plans.
 
   CONTRACTS PURCHASED  UNDER GOVERNMENT DEFERRED COMPENSATION PLANS
   -----------------------------------------------------------------
 
  You can exclude a portion of your compensation from gross income if you
participate in a deferred compensation plan maintained by
 
     . a state,
 
     . a political subdivision of a state,
 
     . an agency or intrumentality or a state or political subdivision of a
       state, or
 
     . a tax-exempt organization.
 
  As a "participant" in such a deferred compensation plan, any amounts you
exclude (and any income on such amounts) will be includible in gross income only
for the taxable year in which such amounts are paid or otherwise made available
to the annuitant or other payee.
 
  In general, the maximum amount of compensation you can deferred under such
tax-favored plans equals the lesser of
 
                                       30
 
<PAGE>
 
     . $7,500 or
 
     . 33 1/3 % of your "includible income" (as defined in the Code).
 
 The deferred compensation plan must satisfy several conditions, including the
following:
 
     . the plan must not permit distributions prior to your separation from
       service (except in the case of an unforeseen emergency), and
 
     . all compensation deferred under the plan shall remain solely the
       employer's property and may be subject to the claims of its
       creditors.
 
 If we make a payment under your contract in the form of an annuity, or in a
single sum such as on surrender or withdrawal, the payment is taxed as ordinary
income.
 
   CONTRACTS PURCHASED FOR "TOP-HEAVY" PLANS
   -----------------------------------------
 
  Certain corporate and H.R. 10 plans may fall within Section 416 of the Code's
definition of "top-heavy plans."  This can happen if the plan holds a
significant amount of its assets for the benefit of "key employees" (as defined
in the Code).  You should consider whether your plan meets the definition.  If
so, you should take care to consider the special limitations applicable to
top-heavy plans and the potentially adverse tax consequences to key employees.
 
   TAX-FREE ROLLOVERS
   ------------------
 
  The discussion above covers certain fully or partially tax-free "rollovers"
from a regular IRA to a ROTH IRA.  You may also make a tax-free rollover from
 
     . a regular IRA to another regular IRA,
 
     . any tax-qualified plan to a regular IRA,
 
     . any tax-qualified plan to another tax-qualified plan of the same type
       (i.e. TSA to TSA, corporate plan to corporate plan, etc.)
 
  We do not have to withhold tax if you roll over your entire distribution and
you request us to pay it directly to the successor plan.  Otherwise, 20%
mandatory withholding will apply and reduce the amount you can roll over to the
new plan, unless you add funds to the rollover from other sources.  Consult a
qualified tax adviser before taking such a distribution.
 
   SEE YOUR OWN TAX ADVISER
   ------------------------
 
  The above description of Federal income tax consequences to owners of and
payees under contracts, and of the different kinds of tax-qualified plans which
may be funded by the contracts, is only a brief summary and is not intended as
tax advice.  It does not include a discussion of Federal estate and gift tax or
state tax consequences.  The rules under the Code governing tax-qualified plans
are extremely complex and often difficult to understand.  Changes to the tax
laws may be enforced retroactively.  Anything less than full compliance with the
applicable rules, all of which are subject to change from time to time, can have
adverse tax consequences.  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, you should consult a qualified tax adviser.
 
 PERFORMANCE INFORMATION
 
  We may advertise total return information about investments made in the
variable investment options. We  refer to this information as "Account level"
performance.   In our Account level advertisements, we usually calculate total
return for 1, 5, and 10 year periods or since the beginning of the applicable
 
                                       31
 
<PAGE>
 
variable investment option.  Total return at the Account level is the percentage
change between
 
     . the value of a hypothetical investment in a variable investment
       option at the beginning of the relevant period, and
 
     . the value at the end of such period.
 
  At Account level, total return reflects adjustments for
 
     . the mortality and expense risk charges,
 
     . the administrative charge,
 
     . the annual contract fee, and
 
     . any withdrawal charge payable if the owner surrenders his contract at
       the end of the relevant period.
 
 Total return at the Account level does not, however, reflect any premium tax
charges.  Total return at the Account level will be lower than that at the Trust
level where comparable charges are not deducted.
 
  We may also advertise total return in a non-standard format in conjunction
with the standard format described above.  The non-standard format is the same
as the standard format, except that it will not reflect any withdrawal charge.
 
  We may advertise "current yield" and "effective yield" for investments in the
Money Market investment option.  CURRENT YIELD refers to the income earned on
your investment in the Money Market investment option over a 7-day period an
then annualized.  In other words, the income earned in the period is assumed to
be earned every 7 days over a 52-week period and stated as a percentage of the
investment.
 
  EFFECTIVE YIELD is calculated in a similar manner but, when annualized, the
income earned by your investment is assumed to be reinvested and thus compounded
over the 52-week period.  Effective yield will be slightly higher than current
yield because of this compounding effect of reinvestment.
 
  We also advertise current yield for investments in the other variable
investment options.  For investments in these options, we calculate current
yield by the following formula:
 
the annualization of the income earned by a
investment in the variable investment option
during a recent 30-day period
                  DIVIDED BY
the maximum offering price per unit of  the
variable investment option at the end of such
30-day period
- ----------------------------------------------
 
 
  In all cases, current yield and effective yield reflect all the recurring
charges at the Account level, but will not reflect any premium tax or any
withdrawal charge.
 
 REPORTS
 
  At least annually, we will send you (1) a report showing the number and value
of the accumulation units in your contract and (2) the financial statements of
the Trust.
 
 VOTING PRIVILEGES
 
  At meetings of the Trust's shareholders, we will generally vote all the shares
of each Fund that we hold in the Account in accordance with instructions we
receive from the owners of contracts that participate in the corresponding
variable investment option.
 
 CERTAIN CHANGES
 
  We reserve the right, subject to applicable law, including any required
shareholder approval,
 
                                       32
 
<PAGE>
 
     . to transfer assets that we determine to be your assets from the
       Account to another separate account or investment option by
       withdrawing the same percentage of each investment in the Account
       with proper adjustments to avoid odd lots and fractions,
 
     . to add or delete variable investment options,
 
     . to change the underlying investment vehicles,
 
     . 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.
 
  Unless otherwise required under applicable laws and regulations, notice to or
approval of owners will not be necessary for us to make such changes.
 
 DISTRIBUTION OF CONTRACTS
 
  Signator Investors, Inc. ("Signator"), formerly John Hancock Distributors,
Inc.,  acts as principal distributor of the contracts sold through this
prospectus. Signator is registered as a broker-dealer under the Securities
Exchange Act of 1934 and a member of the National Association of Securities
Dealers, Inc.  Its address is John Hancock Place, Boston, Massachusetts 02117.
 Signator is a subsidiary of John Hancock.
 
  You can purchase a contract either through Signators registered representative
or through other  broker-dealers whose representatives are authorized by
applicable law to sell annuity products.  We do not expect the compensation to
such broker-dealers to exceed 3.0% of premium payments.  Signator compensates
its registered representatives for sales of the contracts on a commission and
fee service basis.  We, in turn, reimburse Signator for direct and indirect
expenses actually incurred in connection with the marketing and sales of these
contracts.  We offer these contracts on a continuous basis, but neither John
Hancock  is obligated to sell any particular amount of contracts.
 
 IMPACT OF THE YEAR 2000 ISSUE
 
  The advent of the Year 2000 presents us with a technological challenge:
 making our systems function properly with respect to dates in the year 2000 and
after.  In response to that challenge, we have developed and are executing a
plan to modify or replace significant portions of our computer informations
systems and automated technologies.  The plan involves coordination and testing
with business partners in an effort to minimize the possibility that external
factors will adversely impact our systems.  We believe that, with modifications
to existing systems and conversions to new technologies, the Year 2000 will not
pose significant operational problems for our 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 our operations.
 
  We have substantially completed the process of remediating our systems and
expect the compliance testing component of the project to be completed by June,
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.  For more information about the impact of the Year 2000
issue, refer to Note 15 to the Notes to the Financial Statements of John Hancock
Mutual Life Insurance Company included in the Statement of Additional
Information to this prospectus.

  On January 1, 1999, the total value of your contract is $9000 because of good
    investment earnings.
 
  Now assume you make a partial withdrawal of $6000 (no tax withholding) on
    January 2, 1999. In this case, assuming no prior withdrawals, we would
    deduct a CDSL of $399.89.   We withdraw a total of $6399.89 from your
    contract.
 
  $6000.00   --  withdrawal request payable to you
  +  399.89  --  withdrawal charge payable to us
  -----------
  $6399.89 --   total amount withdrawn from your contract
 
HERE IS HOW WE DETERMINE THE WITHDRAWAL CHARGE:
 
 
  We first reduce your $5000 INITIAL PREMIUM PAYMENT by the three annual $30
    contract fees we assessed on January 1, 1997, 1998, and 1999.  We withdraw
    the remaining $4910 from your contract.
 
  $5000
      -30   --  1997 contract fee payable to us
      -30   --  1998 contract fee payable to us
      -30   --  1999 contract fee payable to us
  -------
  $4910  --   amount of your initial premium payment we would consider to be
    withdrawn.
 
  Under the free withdrawal provision, we deduct 10% of the total value of your
    contract at the beginning of the contract year, or $900 (.10 x $9000).   We
    pay the $900 to you as  part of your withdrawal request, and we assess a
    withdrawal charge on the remaining balance of $4010.   Because you made the
    initial premium payment 3 years ago, the withdrawal charge percentage is 7%.
      We deduct the resulting $280.70 from your contract to cover the withdrawal
    charge on your initial premium payment.  We pay the remainder of $3729.30 to
    you as a part of your withdrawal request.
 
  $4910
     -900  --  free withdrawal amount (payable to you)
  -------
  $4010
    x .07
  -------
  $280.70   --  withdrawal charge on initial premium payment (payable to us)

  $4010.00
    -280.70
  ---------
    3729.30 --  part of withdrawal request payable to you
 
  2.We NEXT deem the entire amount of your 1997 PREMIUM PAYMENT to be withdrawn
    and we assess a withdrawal charge on that $1000 amount.  Because you made
    this premium payment 2 years ago, the withdrawal charge percentage is 8%.
      We deduct the resulting $80 from your contract to cover the withdrawal
    charge on your 1997  premium payment. We pay the remainder of $920 to you as
    a part of your withdrawal request.
 
  $1000
   x .08
   -----
      $80   --  withdrawal charge on 1997 premium payment (payable to us)
 
  $1000
    - 80
    ----
    $920   --   part of withdrawal request payable to you
 
  3.We NEXT determine what additional amount we need to withdraw to provide you
    with the total $6000 you requested, after the deduction of the withdrawal
    charge on that additional amount.  We have already allocated $900 from the
    free withdrawal amount, $3729.30 from your initial premium payment, and $920
    from your 1998 PREMIUM PAYMENT.  Therefore, $450.70 is needed to reach
    $6000.
 
  $6000.00   --   total withdrawal amount requested
    -900.00   --   free withdrawal amount
  -3729.30   --   payment deemed from initial premium payment
    -920.00   --   payment deemed from 1997 premium payment
    -------
   $450.70   --   additional payment to you needed to reach $6000
 
  We know that the withdrawal charge percentage for this remaining amount is 8%,
    because you are already deemed to have withdrawn all premiums you paid prior
    to 1998.  We use the following formula to determine how much more we need to
    withdraw:
 
  Remainder due to you   =      Withdrawal needed - [applicable withdrawal
    charge percentage times withdrawal needed]
 
  $450.70  =   x - [.08x]
  $450.70  =  .92x
 
  $450.7
  ------
     0.92     =  x
 
   $489.89  =  x
 
   $489.89    --   deemed withdrawn from 1998 premium payment
  -$450.70   --   part of withdrawal request payable to you
  --------
     $39.19    --   withdrawal charge on 1998 premium deemed withdrawn (payable
    to us)
 
                                       39

  $280.70  --  withdrawal charge on the INITIAL PREMIUM PAYMENT

       APPENDIX C - ILLUSTRATIVE CONTRACT VALUE AND ANNUITY PAYMENT TABLES
 
  The following tables present illustrative periodic contract 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 nine specified variable investment options, assuming
investment by each of those investment options in the corresponding Fund of the
Trust and its predecessors during the periods shown. We have not illustrated the
other investment options because of the limited time that they have been
available. The contracts described in this prospectus were first offered in
1990.
 
   For the years ended December 31, 1986 (and prior thereto), we have calculated
the values 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.
 
  In the tables, we assume
 
     .  the owner made a single purchase payment of $10,000, net of any
       deductions from purchase payments,
 
     .  charges have been assessed at annual rate of 1.40% for mortality and
       expense risks and administrative services, and
 
     . actual investment management fees and other fund expenses for the
       periods illustrated have also been assessed.
 
  Absent expense reimbursements by John Hancock to certain of the Funds for some
periods, the values illustrated would have been lower.
 
 WHAT THE TABLES ILLUSTRATE
 
  Subject to the foregoing, each Table I presents, at yearly intervals,  the
illustrative periodic contract values for each variable investment option which
would have resulted under a contract, if the owner had made a net single
purchase payment of $10,000.  The contract values are based upon the investment
performance of the corresponding Fund.
 
  Subject to the foregoing, each Table II indicates, at annual intervals,
illustrative monthly variable annuity payments for each variable investment
option 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. 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.

                             VARIATIONS IN CHARGES
 
 
     In the future, we may allow a reduction in or the elimination of the
withdrawal charge, the charge for mortality and expense risks, the
administrative services charge,or the annual contract fee.  The affected
contracts would involve sales to groups or classes of individuals in a manner
resulting in a reduction in the expenses associated with the sale of such
contracts and the benefits offered, or the costs associated with administering
or maintaining the contracts.
 
     The entitlement to such a reduction in or elimination of charges and fees
will be determined by John Hancock based upon factors such as the following:
 (1) the size of the initial premium payment, (2) the size of the group or
class, (3) the total amount of premium payments expected to be received from the
group or class and the manner in which premium 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, (5) the purpose for which the contracts are
being purchased and whether that purpose makes it likely that costs and expenses
will be reduced, or (6) the level of commissions paid to selling broker-dealers
or certain financial institutions with respect to contracts within the same
group or class.
 
     We will make any reduction in charges or fees according to our rules in
effect at the time an application for a contract is approved.  We reserve 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.
 
                                  DISTRIBUTION
 
 
     The distribution of the contracts through Signator Investors, Inc.
("Signator") is continuous.  Pursuant to a marketing and distribution agreement
between John Hancock and Signator, the amounts we paid and Signator retained
under that agreement for such services were as follows:

                        CALCULATION OF PERFORMANCE DATA
 
 
     The Account may, from time to time, include in advertisements, sales
literature and reports to owners or prospective investors information relating
to the performance of its variable investment options. The performance
information that may be presented is not an estimate or a guarantee of future
investment performance, and does not represent the actual experience of amounts
invested by a particular owner. Set out below is a description of the methods
used in calculating the performance information for the variable investment
options.
 
     The Account will calculate the average annual total return for each
variable investment option (other than the Money Market option), according to
the following formula prescribed by the SEC:
 
                             P x ( 1 + T ) n = ERV
 
<TABLE>
<CAPTION>
<S>                  <C>
 where               P = a hypothetical initial premium payment of $1,000
 
                     T = average annual total return
                     n =  number of years
                     ERV = ending redeemable value of a hypothetical
                     $1,000 premium payment, made at the beginning of
                     such period (or fractional portion thereof)
</TABLE>
 
 
                                       2
 
<PAGE>
 
     Average annual total return is the annual compounded rate of return for a
variable investment option that would have produced the ending redeemable value
over the stated period if the performance remained constant throughout. The
calculation assumes a single $1,000 premium payment made into the variable
investment option at the beginning of the period and full redemption at the end
of the period. It reflects adjustments for all Trust and contract level charges
except any premium tax charge or charges for optional rider benefits described
in the prospectus.  The annual contract fee has been included as an annual
percentage of assets.
 
     On the basis, the following table shows the average total return for each
variable investment option for the periods ended December 31, 1998:

     For the 7-day period ending December 31, 1998, the Money Market option's
current yield was 3.6 % and its effective yield was 3.6 %.
 
                                       3
 
<PAGE>
 
     The Account will calculate current yield for each variable investment
option (other than the Money Market option) according to the following formula
prescribed by the SEC:
LOGO
 
<TABLE>
<CAPTION>
<S>      <C>
where:   a = net investment income earned during the period by the Fund whose shares are owned by the
         variable investment option
         b = expenses accrued for the period (net of any reimbursements)
         c = the average daily number of accumulation units outstanding during the period
         d = the offering price per accumulation unit on the last day of the period
</TABLE>
 
     According to this formula, yield is determined by dividing the net
investment income per accumulation unit earned during the period (minus the
deduction for mortality and expense risk charge, administration charge and
annual contract fee) by the accumulation unit 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.  Neither the
withdrawal charge nor any charges for premium taxes or optional rider benefits
are reflected in the calculation.
 
     The Account may calculate current yield and effective yield figures for the
Money Market option. The current yield of the Money Market option for a
seven-day period ("base period") will be computed by determining the "net change
in value" (calculated as set forth below) of a hypothetical owner account having
a balance of one unit at the beginning of the period, dividing the net change in
account value 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 365/7,
with the resulting yield figure carried to the nearest hundredth of one percent.
Net changes in value of the hypothetical owner account will include net
investment income of that account (accrued daily dividends as declared by the
Money Market Fund, less daily expenses of the Account) for the period, but will
not include realized gains or losses or unrealized appreciation or depreciation
on the underlying Money Market Fund shares. The mortality and expense risk
charges, administration charge and contract fee are reflected, but the
withdrawal charge and any charge for premium taxes and optional benefits are
not.
 
     The effective yield reflects the effects of compounding and represents an
annualization of the current return.  The formula for effective yield, as
prescribed by the SEC, is:
 
          Effective yield    = (Base period return + 1)/(365/7) / - 1
 
 
                         OTHER PERFORMANCE INFORMATION
 
 
     You can compare performance information at the Account level to other
variable annuity separate accounts or other investment products surveyed by
Lipper Analytical Services, Inc., an independent service that monitors and ranks
the performance of investment companies. Such performance figures are calculated
in accordance with standardized methods established by each reporting service.
 
     We vote any shares held by the Account that are not attributable to
contracts or for which instructions from owners are not received, in proportion
to the instructions we have received from participants in the Account.
 
                        CALCULATION OF ANNUITY PAYMENTS
 
 
CALCULATION OF ANNUITY UNITS
 
 
     We use a measuring device called an "annuity unit" to help us compute the
amount of each monthly payment that is based on a variable investment option.
 Each variable investment option has its own annuity unit with its own annuity
unit value.
 
                                       4
 
<PAGE>
 
     The number of the contract's annuity units for each variable investment
option normally doesn't change while the payee continues to receive payments,
unless the payee makes a transfer from one variable investment option to
another.  The amount of each monthly annuity payment based on a variable
investment option equals the number of the contract's annuity units in that
option times the value of one such unit as of the tenth day preceding the
payment's due date.
 
     To compute the amount of the first annuity payment that is based on any
variable investment option, we first determine the amount of your contract's
value that we will apply to that variable option.  We do this as of 10 calendar
days prior to the date the initial monthly annuity payment is due, in the manner
described in the prospectus under "The annuity period - choosing fixed or
variable annuity payments."
 
     For each variable investment option, we   THEN divide:
 
 
   the resulting value (minus any
        premium tax charge)
 
                 by
 
               $1,000
- -----------------------------------
 
 and multiply the result by
 
 the applicable annuity purchase rate
 set forth in the contract and
 reflecting
 
 (1) the age and, possibly, sex of the
 payee and
 
 (2) the assumed investment rate
 (discussed below)
- ---------------------------------------
 
This computation determines the amount of initial monthly variable annuity
payment to the annuitant from each variable investment option.
 
We then determine the number of annuity units to be credited to the contract
from each of such variable investment options by dividing:
 
 the amount of the initial monthly variable annuity
 payment from that variable annuity option
 
                             BY
 
 the annuity unit value of that variable investment option
 as of 10 calendar days prior to the date the initial
 payment is due
- ----------------------------------------------------------
 
      For example, assume that 10 days before the date of maturity, a contract
has credited to it 4000.000 accumulation units, each having a value of
$12.000000.  Assume, further, that the appropriate annuity purchase rate
 
                                       5
 
<PAGE>
 
in the contract for an assumed investment rate of 3 1/2% is $5.79 per $1000 of
proceeds for the annuity option elected.  The first monthly annuity payment
would be $277.92.
LOGO
 
     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 198.514 ($277.92/$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 $278.91 (198.514 x $1.405000).
 
ANNUITY UNIT VALUES
 
 
     The value of the annuity units varies from day to day, depending on the
investment performance of the variable investment option, the deductions made
against the variable investment option, and the assumed investment rate used in
computing annuity unit values.  Thus, the variable monthly annuity payments vary
in amount from month to month.
 
     We calculate annuity unit value separately for each variable investment
option.  As of the close of each business day, we calculate the value of one
annuity unit by
 
(1)  multiplying the immediately preceding annuity unit value by the sum of one
     plus the applicable net investment rate for the period subsequent to such
     preceding value and then
 
(2)  multiplying this product by an adjustment factor to neutralize the assumed
     investment rate used in determining the amounts of annuity payable.  If
     your contract has an assumed investment rate of 3 1/2 % per year, the
     adjustment factor for a valuation period of one day would be 0.99990575.
      We neutralize the assumed investment rate by applying the adjustment
     factor so that the variable annuity payments will increase only if the
     actual net investment rate of the variable investment option exceeds  3 1/2
     % per year and will decrease only if is less than 3 1/2 % per year.
 
     The amount of the initial variable monthly payment is determined on the
assumption that the actual net investment rate of each variable investment
option used in calculating the "net investment factor" (described below) will be
equal on an annual basis to the "assumed investment rate" (described under "The
annuity period - variable monthly annuity payments" in the prospectus).  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.
 
MORTALITY TABLES
 
 
     The mortality tables used as a basis for both variable and fixed annuity
purchase rates are the 1983a Mortality Tables, with projections of mortality
improvements and with certain age adjustments based on the contract year of
annuitization.  The mortality table used in a Contract purchased in connection
with certain employer-related plans and used in all contracts issued in Montana
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.
 
              ADDITIONAL INFORMATION ABOUT DETERMINING UNIT VALUES
 
 
     The general manner in which we compute annuity unit values is discussed
above.  Like annuity unit values, we calculate accumulation unit values
separately for each variable investment option.  As of the close of each
 
                                       6
 
<PAGE>
 
business day, we calculate the value of one accumulation unit of a variable
investment option by multiplying the immediately preceding accumulation unit
value by the sum of one plus the applicable "net investment rate" for the period
subsequent to such preceding value.  See "Net investment rate" below.
 
NET INVESTMENT RATE
 
 
     For any period, the net investment rate for a variable investment option
equals
 
(1)  the percentage total investment return of the corresponding Fund for that
     period (assuming reinvestment of all dividends and other distributions from
     the Fund), less
 
(2)  for each calendar day in the period, a deduction of 0.003836% (depending on
     the charge for mortality and expense risks) of the value of the variable
     investment option at the beginning of the period, and less
 
(3)  a further adjustment in an appropriate amount if we ever elect to impose a
     charge for our income taxes.
 
ADJUSTMENT OF UNITS AND VALUES
 
 
     We reserve the right to change the number and value of the accumulation
units and/or annuity units credited to your contract, without notice, provided
that strict equity is preserved and the change does not otherwise affect the
benefits, provisions, or investment return of your contract.
 
HYPOTHETICAL EXAMPLE ILLUSTRATING THE CALCULATION OF ACCUMULATION UNIT VALUES
AND ANNUITY UNIT VALUES
 
 
     Assume at the beginning of the period being considered, the value of a
particular variable investment option was $4,000,000. Investment income during
the period totaled $2000, while capital gains were $3000 and capital losses were
$1000.  Assume also that we are not imposing any tax charge.  Charges against
the beginning value of the variable investment option amount to $153.44 assuming
a one day period.  The $153.44 was computed by multiplying the beginning value
of $4,000,000 by the factor 0.00003836. By substituting in the first formula
above, the net investment rate is equal to $3846.56 ($2000 + $3000 - $1000
- -$153.44) divided by $4,000,000 or 0.00096164.
 
     Assume further that each accumulation unit had a value of $11.250000 on the
previous business day, and the value of an annuity unit on such previous date
was $1.0850000. Based upon the experience of the variable investment option
during the period, the value of an accumulation unit at the end of the period
would be [$11.250000 x (1 + .00096164)] or $11.260818.  The value of an annuity
unit at the end of the period would be [$1.0850000 x (1 + .00096164) x
 .99990575] or $1.0859410.  The final figure, .99990575, neutralizes the effect
of a 3 1/2% assumed investment rate so that the annuity unit's change in value
reflects only the actual investment experience of the variable investment
option.
 
                    PURCHASES AND REDEMPTIONS OF FUND SHARES
 
 
     John Hancock purchases and redeems Fund shares for the Account at their net
asset value without any sales or redemption charges.  Each available Fund issues
its own separate series of Fund shares.  Each such series represents an interest
in one of the Funds of the Trust, which corresponds to one of our variable
investment options.  Any dividend or capital gains distributions received by the
Account will be reinvested in shares of that same Fund at their net asset value
as of the dates paid.
 
     On each business day, the account purchases and redeems shares of each fund
for each variable investment option based on, among other things, the amount of
premium payments allocated to that option, dividends reinvested, and transfers
to, from and among investment options, all to be effected as of that date. Such
purchases and redemptions are effective at the net asset value per Trust share
for each fund determined on that same date.

<PAGE>
 
                                  THE ACCOUNT
 
 
     In addition to the assets attributable to contracts, the Account includes
assets derived from charges made by and, possibly, funds contributed by John
Hancock to commence operations of the variable investment option.  From time to
time these additional amounts may be transferred in cash by us to our general
account.  Before any such transfer, we will consider any possible adverse impact
transfer might have on any variable investment option.  The assets of one
variable investment option are not necessarily legally insulated from
liabilities associated with another variable investment option.
 
                           DELAY OF CERTAIN PAYMENTS
 
 
     Ordinarily, upon a surrender or partial withdrawal, we will pay the value
of any accumulation units in a single sum within 7 days after receipt of a
written request at our Annuity Servicing Office.  However, redemption may be
suspended and payment may be postponed under the following conditions:
 
(1)  when the New York Stock Exchange is closed, other than customary weekend
     and holiday closings;
 
(2)  when trading on that Exchange is restricted;
 
(3)  when an emergency exists as a result of which (a) disposal of securities in
     a variable investment option is not reasonably practicable or (b) it is not
     reasonably practicable to determine the value of the net assets of a
     variable investment option;  or
 
(4)  when a governmental body having jurisdiction over the Account by order
     permits such suspension.
 
Rules and regulations of the SEC, if any are applicable, will govern as to
whether conditions in (2) or (3) exist.
 
     We may defer for up to 15 days the payment of any amount attributable to a
premium payment made by check to allow the check reasonable time to clear.
 
     We may also defer payment of surrender proceeds payable out of any
guarantee period for a period of up to 6 months.
 
                       LIABILITY FOR TELEPHONE TRANSFERS
 
 
     If you authorize telephone transfers, you will be liable for any loss,
expense or cost arising out of any unauthorized or fraudulent telephone or fax
instructions which we reasonably believe to be genuine, unless such loss,
expense or cost is the result of our mistake or negligence.  We employ
procedures which provide safeguards against unauthorized transactions, and which
are reasonably designed to confirm that instructions received by telephone are
genuine.  These procedures include
 
 .    requiring personal identification,
 
 .    tape recording calls, and
 
 .    providing written confirmation to the owner.
 
If we do not employ reasonable procedures to confirm that instructions
communicated by telephone are genuine, we may be liable for any loss due to
unauthorized or fraudulent instructions.
 
                               VOTING PRIVILEGES
 
 
     Here's the formula we use to determine the number of Fund shares as to
which you may give instructions:
 
                                       8
 
<PAGE>
 
 the total value of your accumulation
 units value in a variable investment
 option
 
              divided by
 
 the net asset value of 1 share of the
 corresponding Fund
- --------------------------------------
 
 
     At a shareholders' meeting, you may give instructions regarding:
 
 .    the election of the Board of Trustees,
 
 .    the ratification of the selection of independent auditors,
 
 .    the approval of the Trust's investment management agreements,
 
 .    and other matters requiring a vote under the 1940 Act.
 
     The annuitant or other payee will also be entitled to give voting
instructions with respect to the Fund shares corresponding to any variable
investment option under which variable annuity payments are then being made.  We
determine the number of Fund shares for which the payee can give instructions by
dividing the actuarially determined present value of the payee's annuity units
that correspond to that Fund by the net asset value of one share of that Fund.
 
     We will furnish you information and forms so that you may give voting
instructions.
 
     We may own Fund shares that we do not hold in any separate account whose
participants are entitled to give voting instructions.  We will vote such shares
in proportion to the instructions we receive from all variable annuity contract
and variable life insurance policy owners who give us instructions for that
Fund's shares (including owners who participate in separate accounts other than
the Account).
 
     We have designed your voting privileges based upon our understanding of the
requirements of the federal securities laws.  If the applicable laws,
regulations, or interpretations change to eliminate or restrict the need for
such voting privileges, we reserve the right to proceed in accordance with any
such revised requirements.

               REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS
 
To the Directors and Policyholders John Hancock Mutual Life Insurance Company
 
  We have audited the accompanying statutory-basis statements of financial
position of John Hancock Mutual Life Insurance Company as of December 31, 1998
and 1997, and the related statutory-basis statements of operations and changes
in policyholders' contingency reserves and cash flows for the years then ended.
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 Mutual Life Insurance Company at December 31,
1998 and 1997, or the results of its operations or its cash flows for the years
then ended.
 
  Also, in our opinion, the financial statements referred to above present
fairly, in all material respects, the financial position of John Hancock Mutual
Life Insurance Company at December 31, 1998 and 1997, and the results of its
operations and its cash flows for the years then ended in conformity with
accounting practices prescribed or permitted by the Commonwealth of
Massachusetts Division of Insurance.

JOHN HANCOCK MUTUAL LIFE INSURANCE COMPANY
 
NOTES TO STATUTORY-BASIS FINANCIAL STATEMENTS
 
NOTE 1--NATURE OF OPERATIONS AND SIGNIFICANT ACCOUNTING PRACTICES
 
John Hancock Mutual Life Insurance Company (the Company) provides a broad range
of financial services and insurance products. The Company's insurance operations
focus principally in three business units: the Retail Sector, which encompasses
the Company's individual life, annuity, and long-term care operations; Group
Pension, which offers single premium annuity and guaranteed investment contracts
through both the general and separate accounts; and Business Insurance, its
group life, health, and long-term care operations including administrative
services provided to group customers. In addition, through its subsidiaries and
affiliates, the Company also offers a wide range of investment management and
advisory services and other related products including life insurance products
for the Canadian market, sponsorship and distribution of mutual funds, real
estate financing and management, and various other financial services.
Investments in these subsidiaries and other affiliates are recorded on the
statutory equity method.
 
On February 28, 1997, the Company sold a major portion of its group insurance
business to UNICARE Life & Health Insurance Company (UNICARE), a wholly-owned
subsidiary of WellPoint Health Networks Inc. The business sold includes the
Company's group accident and health business and related group life business and
Cost Care, Inc., Hancock Association Services Group and Tri-State, Inc., all
indirect wholly-owned subsidiaries of the Company. The Company retained its
group long-term care operations. Assets equal to liabilities of approximately
$562.4 million at February 28, 1997, subject to the completion of a closing
audit, were transferred to UNICARE in connection with the sale. The gain from
operations was not significant. The insurance business sold was transferred to
UNICARE through a 100% coinsurance agreement. The Company remains liable to its
policyholders to the extent that UNICARE does not meet its contractual
obligations under the coinsurance agreement.
 
The Company has secured a $397.0 million letter of credit facility with a group
of banks. The banks have agreed to issue a letter of credit to the Company
pursuant to which the Company may draw up to $397.0 million for any claims not
satisfied by UNICARE under the coinsurance agreement after the Company has
incurred the first $113.0 million of losses from such claims. The amount
available pursuant to the letter of credit agreement and any letter of credit
issued thereunder will be automatically reduced on a scheduled basis consistent
with the anticipated runoff of liabilities related to the business reinsured
under the coinsurance agreement. The letter of credit and any letter of credit
issued thereunder are scheduled to expire on March 1, 2002.
 
The Company is domiciled in the Commonwealth of Massachusetts and licensed in
all fifty of the United States, the District of Columbia, Puerto Rico, Guam, the
US Virgin Islands, and Canada. The Company distributes its individual products
in North America primarily through a career agency system. The career agency
system is composed of company-owned, unionized branch offices and independent
general agencies. The Company also distributes its individual products through
several alternative distribution channels, including banks, brokers/ dealers and
direct marketing efforts.
 
The Company markets pension and other investment-related products primarily to
sponsors of retirement and savings plans covering employees of private sector
companies, and plans covering public employees and collective bargaining unions
and non-profit organizations. Products are marketed and sold through a
combination of group pension field employee representatives, as well as
marketing personnel and investment professionals employed by the Company.
 
The Company distributes its group benefit products through group
representatives, who are John Hancock employees or through intermediaries, in

NOTES TO STATUTORY-BASIS FINANCIAL STATEMENTS--CONTINUED
NOTE 1--NATURE OF OPERATIONS AND SIGNIFICANT ACCOUNTING PRACTICES--CONTINUED
 
The preparation of financial statements 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 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 investment valuation allowances are
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 policyholders' contingency reserves 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; (9) certain items, including modifications to required policy
reserves resulting from changes in actuarial assumptions are recorded directly
to policyholders' contingency reserves rather than being reflected in income;
and (10) surplus notes are reported as surplus rather than as liabilities. 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: During March 1998, the NAIC adopted the
codification of statutory accounting practices, which is effective in 2001.
Codification 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. Codification will
require adoption by the various states before it becomes the prescribed
statutory basis of accounting for insurance companies domesticated within those
states. Accordingly, before codification becomes effective for the Company, the
Massachusetts Division of Insurance must adopt codification as the prescribed
basis of accounting on which domestic insurers must report their statutory-basis
results to the Division of Insurance. The impact of any such changes on the
Company's statutory surplus 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.

NOTES TO STATUTORY-BASIS FINANCIAL STATEMENTS--CONTINUED
NOTE 1--NATURE OF OPERATIONS AND SIGNIFICANT ACCOUNTING PRACTICES--CONTINUED
 
Valuation of Assets: General account investments are carried at amounts
determined on the following bases:
 
  Bond 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 fair value. The discount or premium on bonds is amortized using the
  interest method.
 
  Investments in affiliates are included on the statutory equity method.
 
  Loan-backed bonds and structured securities are valued at amortized cost using
  the interest method including anticipated prepayments. Prepayment assumptions
  are obtained from broker dealer surveys or internal estimates and are based on
  the current interest rate and economic environment. The retrospective
  adjustment method is used to value all such securities except for
  interest-only securities, which are valued using the prospective method.
 
  The net interest effect of interest rate and currency rate swap transactions
  is recorded as an adjustment of interest income as incurred. The initial cost
  of interest rate cap and floor agreements is amortized to net investment
  income over the life of the related agreement. Gains and losses on financial
  futures contracts used as hedges against interest rate fluctuations are
  deferred and recognized in income over the period being hedged. Net premiums
  related to equity collar positions are amortized into income on a
  straight-line basis over the term of the collars. The collars are carried at
  fair value, with changes in fair value reflected directly in policyholders'
  contingency reserves.
 
  Mortgage loans are carried at outstanding principal balance or amortized cost.
 
  Investment and company-occupied real estate is carried at depreciated cost,
  less encumbrances. Depreciation on investment and company-occupied real estate
  is recorded on a straight-line basis. During 1998, the Company made a
  strategic decision to sell the majority of its commercial real estate
  portfolio. Properties with a book value of $533.8 million were sold in 1998,
  and an additional $1.1 billion of real estate is expected to be sold in 1999.
  Net gains on the properties sold in 1998 amounted to $64.3 million. Those
  properties to be sold subsequent to December 31, 1998 are carried at the lower
  of depreciated cost at the date a determination to sell was made or fair
  value. Accumulated depreciation amounted to $370.0 million and $470.5 million
  at December 31, 1998 and 1997, respectively.
 
  Real estate acquired in satisfaction of debt and real estate held for sale,
  which are classified with investment properties, are carried at the lower of
  cost or fair value.
 
  Policy loans are carried at outstanding principal balance, not in excess of
  policy cash surrender value.
 
  Other invested assets, which are classified with other general account assets,
  include real estate and energy joint ventures and limited partnerships and
  generally are valued based on the Company's equity in the underlying net
  assets.
 
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. The Company historically
makes additional contributions to the AVR in excess of the required amounts to
account for potential losses and risks in the investment portfolio when the
Company believes such provisions are prudent. During 1998, in connection with
the Company's plans to dispose of certain real estate holdings, additional
contributions were recorded that resulted in the AVR exceeding the prescribed
maximum reserve level by $111.3 million. The Company received permission from
the Massachusetts Division of Insurance to record its AVR in excess of the
prescribed maximum reserve level. Changes to the AVR are charged or credited
directly to policyholders' contingency reserves.

NOTE 1--NATURE OF OPERATIONS AND SIGNIFICANT ACCOUNTING PRACTICES--CONTINUED
 
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, 1998, the IMR, net of 1998 amortization of $34.9 million, amounted to $261.6
million which is included in other policy obligations. The corresponding 1997
amounts were $25.2 million and $165.6 million, respectively.
 
Property and Equipment: Data processing equipment, which amounted to $31.4
million in 1998 and $30.0 million in 1997 and is included in other general
account assets, is reported at depreciated cost, with depreciation recorded on a
straight-line basis. Non-admitted furniture and equipment also is depreciated on
a straight-line basis. The useful lives of these assets range from three to
twenty years. Depreciation expense was $20.1 million in 1998 and $21.8 million
in 1997.
 
Separate Accounts: Separate account assets and liabilities reported in the
accompanying statements of financial position represent funds that are
separately administered, principally for annuity contracts and 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 fair 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 Value Disclosure 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 certain
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 14.
 
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 subsidiary
  investments which are carried at equity values, are based on quoted market
  prices.
 
  The fair value for mortgage loans is estimated using discounted cash flow
  analyses using interest rates adjusted to reflect the credit characteristics
  of the underlying loans. Mortgage loans with similar characteristics and
  credit risks are aggregated into qualitative categories for purposes of the
  fair value calculations.
 
  The carrying amounts in the statement of financial position for policy loans
  approximate their fair values.

NOTES TO STATUTORY-BASIS FINANCIAL STATEMENTS--CONTINUED
NOTE 1--NATURE OF OPERATIONS AND SIGNIFICANT ACCOUNTING PRACTICES--CONTINUED
 
  Fair values for futures contracts are based on quoted market prices. Fair
  values for interest rate swap, cap and floor agreements, swaptions, and
  currency swap agreements and equity collar agreements are based on current
  settlement values. The current settlement values are based on brokerage quotes
  that utilize pricing models or formulas using current assumptions.
 
  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, 1998. The fair
  value for commitments to purchase other invested assets approximates the
  amount of the initial commitment.
 
  Fair values for the Company's guaranteed investment contracts are estimated
  using discounted cash flow calculations, based on interest rates currently
  being offered for similar contracts with maturities consistent with those
  remaining for the contracts being valued. The fair value for fixed-rate
  deferred annuities is the cash surrender value, which represents the account
  value less applicable surrender charges. Fair values for immediate annuities
  without life contingencies and supplementary contracts without life
  contingencies are estimated based on discounted cash flow calculations using
  current market rates.
 
Capital Gains and Losses: Realized capital gains and losses are determined using
the specific identification method. Realized capital gains and losses, net of
taxes and amounts transferred to the IMR, are included in net income. Unrealized
gains and losses, which consist of market value and book value adjustments, are
shown as adjustments to policyholders' contingency reserves.
 
Foreign Exchange Gains and Losses: Foreign exchange gains and losses are
reflected as direct credits or charges to policyholders' contingency reserves
through unrealized capital gains and losses.
 
Policy Reserves: Life, annuity, and accident and health benefit reserves are
developed by actuarial methods and are determined based on published tables
using statutorily specified interest rates and valuation methods that will
provide, in the aggregate, reserves that are greater than or equal to the
minimum or guaranteed policy cash values or the amounts required by the
Commonwealth of Massachusetts Division of Insurance. Reserves for traditional
individual life insurance policies are maintained using the 1941, 1958 and 1980
Commissioner's Standard Ordinary and American Experience Mortality Tables, with
assumed interest rates ranging from2 1/2% to 6%, and using principally the net
level premium method for policies issued prior to 1978 and a modified
preliminary term method for policies issued in 1979 and later. Annuity and
supplementary contracts with life contingency reserves are based principally on
modifications of the 1937 Standard Annuity Table, the Group Annuity Mortality
Tables for 1951, 1971 and 1983, the 1971 Individual Annuity Mortality Table and
the a-1983 Individual Annuity Mortality Table, with interest rates generally
ranging from 2% to8 3/4%.
 
Reserves for deposit administration funds and immediate participation guarantee
funds are based on accepted actuarial methods at various interest rates.
Accident and health policy reserves generally are calculated using either the
two-year preliminary term or the net level premium method based on various
morbidity tables.

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 and its
subsidiaries and affiliates are combined in filing a consolidated federal income
tax return for the group. The federal income taxes of the Company are determined
on a separate return basis with certain adjustments.
 
Income before taxes differs from taxable income principally due to tax-exempt
investment income, dividends-received tax deductions, the limitation placed on
the tax deductibility of mutual companies' policyholder dividends, accelerated
depreciation, differences in policy and contract liabilities for tax return and
financial statement purposes, capitalization of policy acquisition expenses for
tax purposes and other adjustments prescribed by the Internal Revenue Code.
 
When determining its consolidated federal income tax expense, the Company uses a
number of estimated amounts that may change when the actual tax return is
completed. In addition, the Company must also use an estimated differential
earnings rate (DER) to compute the equity tax portion of its federal income tax
expense. Because the DER is set by the Internal Revenue Service after completion
of the financial statements, a true-up adjustment (i.e., effect of the
difference between the estimated and final DER) is necessary.
 
Amounts for disputed tax issues relating to prior years are charged or credited
directly to policyholders' contingency reserves.
 
The Company made federal tax payments of $74.9 million in 1998 and $146.4
million in 1997.
 
Adjustments to Policy Reserves and Policyholders' and Beneficiaries' Funds: From
time to time, the Company finds it appropriate to modify certain required policy
reserves because of changes in actuarial assumptions. Reserve modifications
resulting from such determinations are recorded directly to policyholders'
contingency reserves. During 1997, the Company refined certain actuarial
assumptions inherent in the calculation of reserves related to guaranteed
investment contracts and AIDS claims under individual insurance policies
resulting in a net $1.4 million increase in policyholders' contingency reserves
at December 31, 1997. No additional refinements were made during 1998.
 
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.

Guaranty Fund Assessments: Guaranty fund assessments are accrued when the
Company receives notice that an amount is payable to a guaranty fund.
 
Reclassification: Certain 1997 amounts have been reclassified to conform to the
1998 presentation.
 
NOTE 2--SURPLUS NOTES
 
On February 25, 1994, the Company issued $450 million of surplus notes that bear
interest at7 3/8% and are scheduled to mature on February 15, 2024. The issuance
of the surplus notes was approved by the Commonwealth of Massachusetts Division
of Insurance and any payment of interest on and principal of the notes may be
made only with the prior approval of the Commissioner of the Commonwealth of
Massachusetts Division of Insurance. Surplus notes are reported as part of
policyholders' contingency reserves rather than liabilities. Interest of $33.2
million was paid on the notes during 1998 and 1997.
 
NOTE 3--BORROWED MONEY
 
At December 31, 1998, the Company had a $500 million syndicated line of credit.
There are 26 banks that are part of the syndicate which is under the leadership
of Morgan Guaranty Trust Company of New York. The banks will commit, when
requested, to loan funds at prevailing interest rates as determined in
accordance with the line of credit agreement, which terminates on June 30, 2001.
The agreement does not contain a material adverse change clause. Under the terms
of the agreement, the Company is required to maintain certain minimum levels of
net worth and comply with certain other covenants. As of December 31, 1998,
these covenants were met; however, no amounts had been borrowed under this
agreement.
 
In 1995, the Company issued $213.1 million of debt through a Real Estate
Mortgage Investment Conduit (REMIC). As collateral to the debt, the Company
pledged $1,065.8 million of commercial mortgages to the REMIC Trust. In
addition, the Company guaranteed the timely payment of principal and interest on
the debt. The debt was issued in two notes of equal amounts. The interest rates
on the class A1 and A2 notes are calculated on a floating basis, based on the
monthly LIBOR rates plus 22 and 27 basis points, respectively. The LIBOR rates
were 5.06% and 5.72%, respectively, at December 31, 1998 and 1997. The class A1
notes were fully repaid on March 25, 1997 and the class A2 notes were fully
repaid on June 25, 1998. The outstanding balances of the notes totaled $42.6
million at December 31, 1997 and are included in other general account
obligations.
 
In 1996, the Company issued $292.0 million of additional debt through a REMIC
(REMIC II). As collateral to the debt, the Company pledged $1,455.4 million of
commercial mortgages to the REMIC II Trust. The debt was issued in two notes.
The interest rates on the class A1 and A2 notes are calculated on a floating
basis, based on the monthly LIBOR rate plus 5 and 19 basis points, respectively.
The class A1 notes were fully repaid on December 26, 1997 and the class A2 notes
were fully repaid on December 28, 1998. The outstanding balances of the notes
totaled $161.0 million at December 31, 1997 and are included in other general
account obligations.
 
At December 31, 1997, the Company had a short-term note of $75.0 million payable
to an affiliate at a variable rate of interest. The note, which is included in
other general account obligations, was repaid on January 5, 1998.
 
Interest paid on borrowed money was $6.6 million and $21.2 million during 1998
and 1997, respectively.

Gross gains of $126.4 million in 1998 and $61.5 million in 1997 and gross losses
of $62.3 million in 1998 and $86.6 million in 1997 were realized from the sale
of bonds.
 
At December 31, 1998, bonds with an admitted asset value of $18.9 million were

The cost of common stocks was $258.4 million and $148.0 million at December 31,
1998 and 1997, respectively. At December 31, 1998, gross unrealized appreciation
on common stocks totaled $64.9 million, and gross unrealized depreciation
totaled $54.0 million. The fair value of preferred stock totaled $832.4 million
at December 31, 1998 and $695.8 million at December 31, 1997.
 
The Company participates in a security lending program for the purpose of
enhancing income on securities held. At December 31, 1998 and 1997, $421.5
million and $217.0 million, respectively, of the Company's bonds and stocks were
on loan to various brokers/dealers, but were fully collateralized by cash and
U.S. government securities in an account held in trust for the Company. Such
assets reflect the extent of the Company's involvement in securities lending,
not the Company's risk of loss.
 
Mortgage loans with outstanding principal balances of $56.4 million, bonds with
amortized cost of $105.1 million and real estate with depreciated cost of $14.6
million were non-income producing for the twelve months ended December 31, 1998.
 
Restructured commercial mortgage loans aggregated $230.5 million and $314.3
million as of December 31, 1998 and 1997, respectively. The expected gross
interest income that would have been recorded had the loans been current in
accordance with the original loan agreements and the actual interest income
recorded were as follows:

Generally, the terms of the restructured mortgage loans call for the Company to
receive some form or combination of an equity participation in the underlying
collateral, excess cash flows or an effective yield at the maturity of the loans
sufficient to meet the original terms of the loans.
 
At December 31, 1998, the mortgage loan portfolio was diversified by geographic
region and specific collateral property type as displayed below. The Company
controls credit risk through credit approvals, limits and monitoring procedures.

At December 31, 1998, the fair values of the commercial and agricultural
mortgage loan portfolios were $7.3 billion and $1.3 billion, respectively. The
corresponding amounts as of December 31, 1997 were approximately $6.7 billion
and $1.5 billion, respectively.
 
The maximum and minimum lending rates for mortgage loans during 1998 were 9.68%
and 6.82% for agricultural loans, 9.25% and 6.73% for other properties, and 7.5%
and 6.65% for purchase money mortgages. Generally, the percentage of any loan to
the value of security at the time of the loan, exclusive of insured, 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 provisions 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
 
Premiums, benefits and reserves associated with reinsurance assumed in 1998 were
$784.0 million, $310.0 million, and $7.7 million, respectively. The
corresponding amounts in 1997 were $787.1 million, $386.6 million, and $7.5
million, respectively.
 
The Company cedes business to reinsurers to share risks under life, health and
annuity contracts for the purpose of reducing exposure to large losses.
Premiums, benefits and reserves ceded to reinsurers in 1998 were $873.9 million,
$772.5 million and $712.2 million, respectively. The corresponding amounts in
1997 were $801.8 million, $767.9 million and $594.9 million, respectively.
 
Premiums, benefits, and reserves ceded related to the group accident and health
and related group life business sold in 1997, included in the amounts above,
were $458.2 million, $481.2 million, and $238.6 million, respectively, at
December 31, 1998. The corresponding amounts in 1997 were $487.4 million, $503.3
million, and $247.9 million, respectively.
 
Amounts recoverable on paid claims and funds withheld from reinsurers were as
follows:

The Company has a coinsurance agreement with another insurer to cede 100% of its
individual disability business. Reserves ceded under this agreement, included in
the amount shown above, were $251.1 million at December 31, 1998 and $236.3
million at December 31, 1997.
 
John Hancock Variable Life Insurance Company (Variable Life, a wholly-owned
affiliate) has a modified coinsurance agreement with the Company to reinsure 50%
of Variable Life's 1994 through 1998 issues of flexible premium variable life
insurance and scheduled premium variable life insurance policies. In connection
with this agreement, the Company transferred $4.9 million and $22.0 million of
cash for tax, commission, and expense allowances to Variable Life, which
decreased the Company's net gain from operations by $22.2 million and $10.1
million in 1998 and 1997, respectively.

NOTE 7--REINSURANCE--CONTINUED
 
Variable Life also has a modified coinsurance agreement with the Company to
reinsure 50% of Variable Life's 1995 through 1998 issues of certain retail
annuity contracts (Independence Preferred and Declaration). In connection with
this agreement, the Company made a net cash payment of $12.7 million in 1998 and
received a net cash payment of $1.1 million in 1997 of cash for surrender
benefits, tax, reserve increase, commission, expense allowances and premium.
This agreement decreased the Company's net gain from operations by $8.4 million
and $9.8 million in 1998 and 1997, respectively.
 
Effective January 1, 1997, Variable Life entered into a stop-loss agreement with
the Company to reinsure mortality claims in excess of 110% of expected mortality
claims in 1998 and 1997 for all policies that are not reinsured under any other
indemnity agreement. In connection with the agreement, the Company received $1.0
million and transferred $2.4 million of cash for mortality claims to Variable
Life, which increased by $0.5 million and decreased by $1.3 million the
Company's net gain from operations in 1998 and 1997, 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 insurer.
 
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, 1998 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--BENEFITS PLANS AND OTHER POSTRETIREMENT BENEFIT PLANS
 
The Company provides retirement benefits to substantially all employees and
general agency personnel. These benefits are provided through both defined
benefit and defined contribution pension plans. Pension benefits under the
defined benefit plans are based on years of service and average compensation
generally during the five years prior to retirement. Benefits related to the
Company's defined benefit pension plans paid to employees and retirees covered
by annuity contracts issued by the Company amounted to $92.6 million in 1998 and
$89.7 million in 1997.
 
The Company's funding policy for qualified defined benefit plans is to
contribute annually an amount in excess of the minimum annual contribution
required under the Employee Retirement Income Security Act (ERISA). This amount
is limited by the maximum amount that can be deducted for federal income tax
purposes. The funding policy for nonqualified defined benefit plans is to
contribute the amount of the benefit payments made during the year. Plan assets
consist principally of listed equity securities, corporate obligations and U.S.
government securities.

NOTES TO STATUTORY-BASIS FINANCIAL STATEMENTS--CONTINUED
NOTE 8--BENEFITS PLANS AND OTHER POSTRETIREMENT BENEFIT PLANS--CONTINUED
 
Defined contribution plans include The Investment Incentive Plan (TIP) and the
Savings and Investment Plan (SIP). Employees are eligible to participate in TIP
after one year of service and may contribute up to the lesser of 15% of their
salary or $10,000 annually to the plan. The Company matches the first 2% of
pre-tax contributions and makes an additional annual profit sharing contribution
for employees who have completed at least two years of service. Through SIP,
marketing representatives, sales managers and agency managers are eligible to
contribute up to the lesser of 13% of their salary or $10,000. The Company
matches the first 3% of pretax contributions for marketing representatives and
the first 2% of pre-tax contributions for sales managers and agency managers.
The Company makes an annual profit sharing contribution of up to 1% for sales
managers and agency managers who have completed at least two years of service.
The expense for defined contribution plans was $8.1 million and $6.2 million in
1998 and 1997, respectively.
 
Since 1988, the Massachusetts Division of Insurance has provided the Company
with approval to recognize the pension plan prepaid expense, if any, in
accordance with the requirements of SFAS No. 87, "Employers' Accounting for
Pensions." The Company furnishes the Division of Insurance with an actuarial
certification of the prepaid expense computation on an annual basis.
 
In addition to the Company's defined benefit pension plans, the Company has
employee welfare plans for medical, dental, and life insurance covering most of
its retired employees and general agency personnel. Substantially all employees
may become eligible for these benefits if they reach retirement age while
employed by the Company. The postretirement health care and dental coverages are
contributory based on service for post January 1, 1992 non-union retirees. A
small portion of pre-January 1, 1992 non-union retirees also contribute. The
applicable contributions are based on service.
 
In 1993, the Company changed its method of accounting for the costs of its
retiree benefit plans to the accrual method and elected to amortize its
transition liability for retirees and fully eligible or vested employees over
twenty years.
 
Since 1993, the Company has funded a portion of the postretirement obligation.
The Company's policy is to fund postretirement benefits for non-union employees
to the maximum amount that can be deducted for federal income tax purposes and
to fund the benefits for union employees, which are fully tax qualified, at
sufficient amounts so that the total accrued liability related to postretirement
benefits is approximately zero. As of December 31, 1998, plan assets related to
non-union employees were comprised of an irrevocable health insurance contract
to provide future health benefits to retirees while plan assets related to union
employees were comprised of approximately 70% equity securities and 30% fixed
income investments.
 
The Company provides additional compensation to employees based on achievement
of annual and long-term corporate financial objectives.

assumed to decrease gradually to 5.00 percent in 2001 and remain at that level
thereafter.

NOTE 9--AFFILIATES
 
The Company has subsidiaries and affiliates in a variety of industries including
domestic and foreign life insurance and domestic property casualty insurance,
real estate, mutual funds, investment brokerage and various other financial
services entities.
 
Total assets of unconsolidated majority-owned affiliates amounted to $13.8
billion at December 31, 1998 and $12.4 billion at December 31, 1997; total
liabilities amounted to $12.5 billion at December 31, 1998 and $11.1 billion at
December 31, 1997; and total net income was $148.5 million in 1998 and $184.8
million in 1997.
 
The Company customarily engages in transactions with its unconsolidated
affiliates, including the cession and assumption of certain insurance business
under the terms of established reinsurance agreements (See Note 7). Various
services are performed by the Company for certain affiliates for which the
Company is reimbursed on the basis of cost. Certain affiliates have entered into
various financial arrangements relating to borrowings and capital maintenance
under which agreements the Company would be obligated in the event of
nonperformance by an affiliate (see Note 13).
 
The Company received dividends of $62.2 million and $65.9 million in 1998 and
1997, respectively, from unconsolidated affiliates.

Financial futures contracts are used principally to hedge risks associated with
interest rate fluctuations on sales of guaranteed investment contracts. 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
opposite changes in the value of the hedged items. The contracts or notional
amounts of the contracts represent the extent of the Company's involvement but
not the future cash requirements, as the Company intends to close the open
positions prior to settlement. The futures contracts expire in 1999.
 
The Company uses futures contracts, interest rate swap, cap and floor
agreements, swaptions, and currency rate swap agreements for other than trading
purposes to hedge and manage its exposure to changes in interest rate levels,
foreign exchange rate fluctuations and to manage duration mismatch of assets and
liabilities.
 
The Company invests in common stock that is subject to fluctuations from market
value changes in stock prices. The Company sometimes seeks to reduce its market
exposure to such holdings by entering into equity collar agreements. A collar
consists of a call that limits the Company's potential for gain from
appreciation in the stock price as well as a put that limits the Company's loss
potential from a decline in the stock price.
 
The interest rate swap agreements expire in 1999 to 2028. The interest rate cap
and floor agreements expire in 2000 to 2007. Interest rate swaption agreements
expire in 2025. The currency rate swap agreements expire in 1999 to 2018. The
equity collar agreements expire in 2003.
 
The Company's exposure to credit risk is the risk of loss from a counterparty
failing to perform to the terms of the contract. The Company continually
monitors its position and the credit ratings of the counterparties to these
derivative instruments. To limit exposure associated with counterparty
nonperformance on interest rate and currency swap 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 such losses, if any, would be immaterial. Futures contracts trade on
organized exchanges and, therefore, have minimal credit risk.

JOHN HANCOCK MUTUAL LIFE INSURANCE COMPANY
 
NOTES TO STATUTORY-BASIS FINANCIAL STATEMENTS--CONTINUED
NOTE 13--COMMITMENTS AND CONTINGENCIES
 
The Company has extended commitments to purchase long-term bonds, preferred and
common stocks, and other invested assets and issue real estate mortgages
totaling $329.1 million, $72.0 million, $214.1 million and $471.4 million,
respectively, at December 31, 1998. If funded, loans related to real estate
mortgages would be fully collateralized by related properties. The Company
monitors the credit worthiness of borrowers under long-term bond commitments and
requires collateral as deemed necessary. The estimated fair value of the
commitments described above is $1.1 billion at December 31, 1998. The majority
of these commitments expire in 1999.
 
During 1996, the Company entered into a credit support and collateral pledge
agreement with the Federal National Mortgage Association (FNMA). Under the
agreement, the Company sold $532.8 million of commercial mortgage loans and
acquired an equivalent amount of FNMA securities. The Company completed similar
transactions with FNMA in 1991 for $1.042 billion and in 1993 for $71.9 million.
FNMA is guarantying the full face value of the bonds of the three transactions
to the bondholders. However, the Company has agreed to absorb the first 12.25%
of the principal and interest losses (less buy-backs) for the pools of loans
involved in the three transactions, based on the total outstanding principal
balance of $1.036 billion as of July 1, 1996, but is not required to commit
collateral to support this loss contingency. At December 31, 1998, the aggregate
outstanding principal balance of all the remaining pools of loans from 1991,
1993, and 1996 was $602.8 million.
 
Historically, the Company has experienced losses of less than one percent on its
multi-family mortgage portfolio. Mortgage loan buy-backs required by the FNMA in
1998 and 1997 amounted to $4.6 million and $4.1 million, respectively.
 
During 1996, the Company entered into a credit support and collateral pledge
agreement with the Federal Home Loan Mortgage Corporation (FHLMC). Under the
agreement, the Company sold $535.3 million of multi-family loans and acquired an
equivalent amount of FHLMC securities. FHLMC is guarantying the full face value
of the bonds to the bondholders. However, the Company has agreed to absorb the
first 10.5% of original principal and interest losses (less buy-backs) for the
pool of loans involved but is not required to commit collateral to support this
loss contingency. Historically, the Company has experienced total losses of less
than one percent on its multi-family loan portfolio. At December 31, 1998, the
aggregate outstanding principal balance of the pools of loans was $445.8
million. There were no mortgage loans buy-backs in 1998 and 1997.
 
The Company has a support agreement with Variable Life under which the Company
agrees to continue directly or indirectly to own all of Variable Life's common
stock and maintain Variable Life's net worth at not less than $1 million.
 
The Company has a support agreement with John Hancock Capital Corporation
(JHCC), a non-consolidated wholly-owned subsidiary, under which the Company
agrees to continue directly or indirectly to own all of JHCC's common stock and
maintain JHCC's net worth at not less than $1 million. JHCC's outstanding
borrowings as of December 31, 1998 were $411.7 million for short-term borrowings
and $173.4 million for notes payable.
 
The Company is subject to insurance guaranty fund laws in the states in which it
does business. These laws assess insurance companies amounts to be used to pay
benefits to policyholders and claimants of insolvent insurance companies. Many
states allow these assessments to be credited against future premium taxes. The
Company believes such assessments in excess of amounts accrued will not
materially affect its financial position.
 
In the normal course of its business operations, the Company is involved with
litigation from time to time with claimants, beneficiaries and others, and a
number of litigation matters were pending as of December 31, 1998. 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 or results of operations of the Company.

NOTE 13--COMMITMENTS AND CONTINGENCIES--CONTINUED
 
During 1997, the Company entered into a court approved settlement relating to a
class action lawsuit involving certain individual life insurance policies sold
from 1979 through 1996. In entering into the settlement, the Company
specifically denied any wrongdoing. The Company has established a litigation
reserve in connection with the settlement to provide for relief to class members
and for legal and administrative costs associated with the settlement. The
reserve has been charged, net of the related tax effect, directly to
policyholders' contingency reserves of the Company. Given the uncertainties
associated with estimating the reserve, it is possible that the final cost of
the settlement could be different from the amounts presently provided for by the
Company. However, the Company does not believe that the ultimate resolution of
the settlement will have a material adverse effect on the Company's financial
position.

NOTE 15--IMPACT OF YEAR 2000 (UNAUDITED)
 
The Company is executing its plan to address the impact of the Year 2000 issues
that result from computer programs being written using two digits to reflect the
year rather than four to define the applicable year and century. Historically,
the first two digits were hardcoded to save memory.

NOTES TO STATUTORY-BASIS FINANCIAL STATEMENTS--CONTINUED
NOTE 15--IMPACT OF YEAR 2000 (UNAUDITED)--CONTINUED
 
Many of the Company's computer programs that have date-sensitive software may
recognize a date using "00" as the year 1900 rather than the year 2000. This
could result in an information technology (IT) system failure or miscalculations
causing disruptions of operations, including, among other things, a temporary
inability to process transactions, send invoices or engage in similar normal
business activities. In addition, non-IT systems including, but not limited to,
security alarms, elevators and telephones are subject to malfunction due to
their dependence on embedded technology such as microcontrollers for proper
operation. As described, the Year 2000 project presents a number of challenges
for financial institutions since the correction of Year 2000 issues in IT and
non-IT systems will be complex and costly for the entire industry.
 
The Company began to address the Year 2000 project as early as 1994. The
Company's plan to address the Year 2000 Project includes an awareness campaign,
an assessment period, a renovation stage, validation work and an implementation
of Company solutions.
 
The continuous awareness campaign serves several purposes: defining the problem,
gaining executive level support and sponsorship, establishing a team and overall
strategy, and assessing existing information system management resources.
Additionally, the awareness campaign establishes an education process to ensure
that all employees are aware of the Year 2000 issue and knowledgeable of their
role in securing solutions.
 
The assessment phase, which was completed for both IT and non-IT systems as of
April 1998, included the identification, inventory, analysis, and prioritization
of IT and non-IT systems and processes to determine their conversion or
replacement.
 
The renovation stage reflects the conversion, validation, replacement, or
elimination of selected platforms, applications, databases and utilities,
including the modification of applicable interfaces. Additionally, the
renovation stage includes performance, functionality, and regression testing and
implementation. As of December 31, 1998, the renovation phase was substantially
complete for computer applications, systems and desktops. For all remaining
components, the renovation phase is underway and will be complete before the end
of the second quarter of 1999.
 
The validation phase consists of the compliance testing of renovated systems.
The validation phase is expected to be complete by mid 1999, after renovation is
accomplished. Testing facilities will be used through the remainder of 1999 to
perform special functional testing. Special functional testing includes testing,
as required, with material third parties and industry groups and performing
reviews of "dry runs" of year-end activities. Scheduled testing of material
relationships with third parties is underway. It is anticipated that testing
with material business partners will continue through much of 1999.
 
Finally, the implementation phase involves the actual implementation of
converted or replaced platforms, applications, databases, utilities, interfaces,
and contingency planning. Implementation is being performed concurrently during
the renovation phase and is expected to be completed before the end of the
second quarter of 1999.

NOTE 15--IMPACT OF YEAR 2000 (UNAUDITED)--CONTINUED
 
The costs of the Year 2000 project consist of internal IT personnel and external
costs such as consultants, programmers, replacement software, and hardware. The
costs of the Year 2000 project are expensed as incurred. The project is funded
partially through a reallocation of resources from discretionary projects.
Through December 31, 1998, The Company has incurred and expensed approximately
$9.8 million in related payroll costs for its internal IT personnel on the
project. The estimated range of remaining internal IT personnel costs of the
project is approximately $8 to $9 million. Through December 31, 1998, the
Company has incurred and expensed approximately $36.4 million in external costs
for the project. The estimated range of remaining external costs of the project
is approximately $35 to $36 million. The total costs of the Year 2000 project to
the Company, based on management's best estimates, include approximately $18
million in internal IT personnel, $7.4 million in the external modification of
software, $34.2 million for external solution providers, $19.4 million in
replacement costs of non-compliant IT systems and $12.6 million in oversight,
test facilities and other expenses. Accordingly, the estimated range of total
costs of the Year 2000 project internal and external, is approximately $90 to
$95 million. However, there can be no guarantee that these estimates will be
achieved and actual results could materially differ from those plans. Specific
factors that might cause such material differences include, but are not limited
to, the availability and cost of personnel trained in this area, the ability to
locate and correct all relevant computer codes, and similar uncertainties.
 
The Company's total Year 2000 project costs include the estimated impact of
external solution providers and are based on presently available information.
However, there is no guarantee that the systems of other companies that the
Company's systems rely on will be timely converted, or that a failure to convert
by another company, or a conversion that is incompatible with the Company's
systems, would not have material adverse effect on the Company. It is documented
in trade publications that companies in foreign countries are not acting as
intensively as domestic companies to remediate Year 2000 issues. Accordingly, it
is expected that Company facilities based outside the United States face higher
degrees of risks from data exchanges with material business partners. In
addition, the Company has thousands of individual and business customers that
hold insurance policies, annuities and other financial products of the company.
Nearly all products sold by the Company contain date sensitive data, examples of
which are policy expiration dates, birth dates and premium payment dates.
Finally, the regulated nature of the Company's industry exposes it to potential
supervisory or enforcement actions relating to Year 2000 issues.
 
The Company's contingency planning initiative related to the Year 2000 project
is underway. The plan is addressing the Company's readiness as well as that of
material business partners on whom the Company depends. The Company's
contingency plans are being designed to keep each subsidiary's operations
functioning in the event of a failure or delay due to the Year 2000 record
format and date calculation changes. Contingency plans are being constructed
based on the foundation of extensive business resumption plans that the Company
has maintained and updated periodically, which outline responses to situations
that may affect critical business functions. These plans also provide emergency
operations guidance, which defines a documented order of actions to respond to
problems. These extensive business resumption plans are being enhanced to cover
Year 2000 situations.

                    JOHN HANCOCK VARIABLE ANNUITY ACCOUNT U
 
                         NOTES TO FINANCIAL STATEMENTS
 
                               DECEMBER 31, 1998
 
1. ORGANIZATION
 
  John Hancock Variable Annuity Account U (the Account) is a separate investment
account of John Hancock Mutual Life Insurance Company (JHMLICO or John Hancock).
 The Account was formed to fund variable annuity contracts (Contracts) issued by
JHMLICO.  Currently, the Account funds the Accommodator and Independence Annuity
Contracts.  The Account is operated as a unit investment trust registered under
the Investment Company Act of 1940, as amended, and currently consists of
twenty-three 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 twenty-three Portfolios of the Fund which are
currently available are Large Cap Growth, Sovereign Bond, International Equity
Index (formerly, International Equities), Small Cap Growth, International
Balanced, Mid Cap Growth, Large Cap Value, Money Market, Mid Cap Value,
Diversified Mid Cap Growth (formerly, Special Opportunities), Real Estate
Equity, Growth & Income, Managed, Short-Term Bond (formerly, Short-Term U.S.
Government), Small Cap Value, International Opportunities, Equity Index,
Strategic Bond, Emerging Markets Equity, Global Equity, Bond Index, Small/Mid
Cap CORE and High Yield Bond Subaccounts).  Each Portfolio has a different
investment objective.
 
  The assets of the Account are the property of JHMLICO.  The portion of the
Account's assets applicable to the Contracts may not be charged with liabilities
arising out of any other business JHMLICO 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 value 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
JHMLICO, which is taxed as a life insurance company under the Internal Revenue
Code.  JHMLICO has the right to charge the Account any federal income taxes, or
provisions 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.  JHMLICO 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
 
  JHMLICO 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 1.00% and 1.40% of net assets of the Accommodator and
Independence Contracts, respectively.
 
  JHMLICO makes certain other deductions from contractowner payments for premium
taxes, guaranteed minimum death benefit, sales charges on purchases
(Accommodator only) and the surrender fee and annual contract fee (Independence
only), which are accounted for as a reduction of net assets resulting from
contractowner transactions.

6. IMPACT OF YEAR 2000 (UNAUDITED)
 
  The John Hancock Variable Annuity Account U, along with John Hancock Mutual
Life Insurance Company, its ultimate parent (together, John Hancock), is
executing its plan to address the impact of the Year 2000 issues that result
from computer programs being written using two digits to reflect the year rather
than four to define the applicable year and century.  Historically, the first
two digits were hardcoded to save memory.  Many of the John Hancock's computer
programs that have date-sensitive software may recognize a date using "00" as
the year 1900 rather than the year 2000.  This could result in an information
technology (IT) system failure or miscalculations causing disruptions of
operations, including, among other things, a temporary inability to process
transactions, send invoices or engage in similar normal business activities.  In
addition, non-IT systems including, but not limited to, security alarms,
elevators and telephones are subject to malfunction due to their dependence on
embedded technology such as microcontrollers for proper operation.  As
described, the Year 2000 project presents a number of challenges for financial
institutions since the correction of Year 2000 issues in IT and non-IT systems
will be complex and costly for the entire industry.
 
  John Hancock began to address the Year 2000 project as early as 1994.  John
Hancock's plan to address the Year 2000 Project includes an awareness campaign,
an assessment period, a renovation stage, validation work and an implementation
of Company solutions.
 
  The continuous awareness campaign serves several purposes: defining the
problem, gaining executive level support and sponsorship, establishing a team
and overall strategy, and assessing existing information system management
resources.  Additionally, the awareness campaign establishes an education
process to ensure that all employees are aware of the Year 2000 issue and
knowledgeable of their role in securing solutions.
 
  The assessment phase, which was completed for both IT and non-IT systems as of
April 1998, included the identification, inventory, analysis, and prioritization
of IT and non-IT systems and processes to determine their conversion or
replacement.
 
  The renovation stage reflects the conversion, validation, replacement, or
elimination of selected platforms, applications, databases and utilities,
including the modification of applicable interfaces.  Additionally, the
renovation stage includes performance, functionality, and regression testing and
implementation.  As of December 31, 1998, the renovation phase was substantially
complete for computer applications, systems and desktops.  For all remaining
components the renovation phase is underway and will be complete before the end
of the second quarter of 1999.
 
  The validation phase consists of the compliance testing of renovated systems.
 The validation phase is expected to be complete by mid 1999, after renovation
is accomplished.  John Hancock will use its testing facilities through the
remainder of 1999 to perform special functional testing.  Special functional
testing includes testing, as required, with material third parties and industry
groups and to perform reviews of "dry run" of year-end activities.  Scheduled
testing of John Hancock's material relationships with third parties is underway.
 It is anticipated that testing with material business partners will continue
through much of 1999.
 
  Finally, the implementation phase involves the actual implementation of
converted or replaced platforms, applications, databases, utilities, interfaces,
and contingency planning.  John Hancock is concurrently performing
implementation during the renovation phase and plans to complete this phase
before the end of the second quarter of 1999.

  The costs of the Year 2000 project consist of internal IT personnel, and
external costs such as consultants, programmers, replacement software, and
hardware.  The costs of the Year 2000 project are expensed as incurred.  The
project is funded partially through a reallocation of resources from
discretionary projects.  Through December 31, 1998, John Hancock has incurred
and expensed approximately $9.8 million in related payroll costs for its
internal IT personnel on the project.  The estimated range of remaining internal
IT personnel costs of the project is approximately $8 to $9 million. Through
December 31, 1998, John Hancock has incurred and expensed approximately $36.4
million in external costs for the project.  The estimated range of remaining
external costs of the project is approximately $35 to $36 million.  The total
costs of the Year 2000 project, based on management's best estimates, include
approximately $18 million in internal IT personnel, $7.4 million in the external
modification of software, $34.2 million for external solution providers, $19.4
million in replacement costs of non-compliant IT systems and $12.6 million in
oversight, test facilities and other expenses.  Accordingly, the estimated range
of total costs of the Year 2000 project, internal and external, is approximately
$90 to $95 million.  However, there can be no guarantee that these estimates
will be achieved and actual results could materially differ from those plans.
Specific factors that might cause such material differences include, but are not
limited to, the availability and cost of personnel trained in this area, the
ability to locate and correct all relevant computer codes, and similar
uncertainties.
 
  John Hancock's total Year 2000 project costs include the estimated impact of
external solution providers and are based on presently available information.
 However, there is no guarantee that the systems of other companies that John
Hancock's systems rely on will be timely converted, or that a failure to convert
by another company, or a conversion that is incompatible with John Hancock's
systems, would not have material adverse effect on John Hancock.  It is
documented in trade publications that companies in foreign countries are not
acting as intensively as domestic companies to remediate Year 2000 issues.
 Accordingly, it is expected that Company facilities based outside the United
States face higher degrees of risks from data exchanges with material business
partners.  In addition, John Hancock has thousands of individual and business
customers that hold insurance policies, annuities and other financial products
of John Hancock.  Nearly all products sold by John Hancock contain date
sensitive data, examples of which are policy expiration dates, birth dates,
premium payment dates.  Finally, the regulated nature of John Hancock's industry
exposes it to potential supervisory or enforcement actions relating to Year 2000
issues.
 
  John Hancock's contingency planning initiative related to the Year 2000
project is underway. The plan is addressing John Hancock's readiness as well as
that of material business partners on whom John Hancock depends.  John Hancock's
contingency plans are being designed to keep each business unit's operations
functioning in the event of a failure or delay due to the Year 2000 record
format and date calculation changes.  Contingency plans are being constructed
based on the foundation of extensive business resumption plans that John Hancock
has maintained and updated periodically, which outline responses to situations
that may affect critical business functions.  These plans also provide emergency
operations guidance, which defines a documented order of actions to respond to
problems.  These extensive business resumption plans are being enhanced to cover
Year 2000 situations.

ITEM 26. PERSONS CONTROLLED BY OR UNDER COMMON CONTROL WITH REGISTRANT
 
  Registrant is a separate account of John Hancock, operated as a unit invest-
ment trust. Registrant supports benefits payable under John Hancock's variable
annuity contracts by investing in shares of John Hancock Variable Series Trust
I (the "Fund") a "series" type of mutual fund, registered under the Investment
Company Act of 1940 (the "Act") as an open-end management investment company.
The Registrant and other separate accounts of John Hancock and John Hancock
Variable Life Insurance Company ("JHVLICO") own all of the Fund's outstanding
shares. The purchasers of variable annuity and variable life insurance con-
tracts, in connection with which the Fund is used, will have the opportunity
to instruct John Hancock and JHVLICO with respect to the voting of the shares
of the Fund held by Registrant as to certain matters. Subject to the voting
instructions, John Hancock directly controls Registrant.

ITEM 27. NUMBER OF CONTRACT OWNERS
     
  As of March 31, 1999, the number of Contract Owners of variable annuity
contracts offered by the Account was 86,880.     
 
ITEM 28. INDEMNIFICATION
 
  Article 9a of the By-Laws of John Hancock provides indemnification to each
present and former director, officer, and employee of John Hancock 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
John Hancock. John Hancock may pay expenses incurred in defending an action or
claim in advance of its final disposition, but only upon receipt of an under-
taking 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 indemni-
fy or advance any expenses to the trustees, shareholders, officers, or employ-
ees 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 Fund
shall indemnify any trustee made a party to any proceeding by reason of serv-
ice 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 of-
ficer 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 indemnifi-
cation 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 indem-
nified 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 de-
fined 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 ulti-
mately 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 trustee or
officer will be found entitled to indemnification.
 
  Similar types of provisions dealing with the indemnification of the Fund's
officers and trustee are hereby incorporated by reference from documents pre-
viously 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 In-
surance Company (Exhibit 5.a. to the 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 I and John Hancock Mutual Life
 
                                      C-3

Insurance Company (Exhibit 5.g. to Post-Effective Amendment No. 9 to the Reg-
istration Statement (File 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 Amendment No. 19 to the Fund's
Registration Statement (File No. 3-2081) dated April __, 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, 1989), 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, 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 Regis-
trant 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 indemnifi-
cation 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.

Post-Effective Amendment does not contain disclosures which would render it

this Post-Effective Amendment to Registrant's Registration Statement with the
Commission.

                                Very truly yours,

                                /s/ Sandra M. DaDalt
