                                    SYNOPSIS
 
   
    You may allocate Purchase Payments to Sub-Accounts of the Variable Account
or to the Fixed Account or both. Purchase Payments must total at least $300 for
the first Contract Year and each Purchase Payment must be at least $25 (see
"Purchase Payments" on page 10). During the Accumulation Phase you may, without
charge, transfer amounts among the Sub-Accounts and between the Sub-Accounts and
the Fixed Account, subject to certain conditions (see "Transfers" on page 11).
    
 
    We do not deduct a sales charge from Purchase Payments; however, if you make
a cash withdrawal, we will, with certain exceptions, deduct a withdrawal charge
of 5% of the amount withdrawn. You may withdraw a portion of your Accumulation
Account each year before we impose the withdrawal charge, and after we have held
a Purchase Payment for five years you may withdraw it
 
                                       3
<PAGE>
   
without charge. We do not impose a withdrawal charge upon annuitization or upon
the transfers described above (see "Cash Withdrawals" and "Withdrawal Charges"
on pages 11 and 14, respectively).
    
 
   
    Special restrictions on withdrawals apply to Qualified Contracts, including
Contracts used with Tax-Sheltered Annuities established pursuant to Section
403(b) of the Internal Revenue Code. In addition, under certain circumstances,
withdrawals may result in tax penalties (see "Federal Tax Status" on page 20).
    
 
   
    If the Annuitant dies before the Annuity Commencement Date, we will pay a
death benefit to your Beneficiary. If the Annuitant dies on or after the Annuity
Commencement Date, we will not pay a death benefit (unless the annuity option
elected provides for a death benefit) (see "Death Benefit" on page 13).
    
 
   
    On each Contract Anniversary and on surrender of the Contract for full
value, we will deduct a contract maintenance charge of $30. After the Annuity
Commencement Date, we deduct this pro rata from each annuity payment we make
during the year (see "Contract Maintenance Charge" on page 14).
    
 
   
    We also deduct a mortality and expense risk charge equal to an annual rate
of 1.30% of the daily net assets of the Variable Account attributable to the
Contracts (see "Mortality and Expense Risk Charge " on page 14).
    
 
   
    We will deduct a charge for premium taxes payable to any governmental entity
(see "Premium Taxes" on page 15).
    
 
   
    Annuity payments will begin on the Annuity Commencement Date. You select the
Annuity Commencement Date, frequency of payments, and the annuity option (see
"Annuity Provisions" on page 16).
    
 
    If you are not satisfied with the Contract, you may return it to us at our
Annuity Service Mailing Address within ten days after we deliver the Contract to
you. When we receive the returned Contract, we will cancel it and refund to you
the full amount of all Purchase Payments made.

                                PERFORMANCE DATA
 
   
    From time to time the Variable Account may publish reports to shareholders,
sales literature and advertisements containing performance data relating to the
Sub-Accounts. Performance data will consist of total return quotations which
will always include quotations for the period subsequent to the date each
Sub-Account became available for investment under the Contracts, and for recent
one year and, when applicable, five and ten year periods. Such quotations for
such periods will be the average annual rates of return required for an initial
Purchase Payment of $1,000 to equal the actual variable accumulation value
attributable to such Purchase Payment on the last day of the period, after
reflection of all applicable withdrawal and Contract charges. In addition, the
Variable Account may calculate non-standardized rates of return that do not
reflect withdrawal and Contract charges. Results calculated without withdrawal
and/or Contract charges will be higher. Performance figures used by the Variable
Account are based on the actual historical performance of the Series Fund for
specified periods, and the figures are not intended to indicate future
performance. The Variable Account may also, from time to time, compare its
investment performance to various unmanaged indices or other variable annuities
and may refer to certain rating and other organizations in its marketing
materials. More detailed information on the computations is set forth in the
Statement of Additional Information.
    
 
                              FINANCIAL STATEMENTS
 
    Financial Statements of the Variable Account and the Company are included in
the Statement of Additional Information.
 
       A WORD ABOUT THE COMPANY, THE VARIABLE ACCOUNT AND THE SERIES FUND
 
THE COMPANY
 
    Sun Life Insurance and Annuity Company of New York is a stock life insurance
company incorporated under the laws of New York on May 25, 1983. Our Home Office
is located at 80 Broad Street, New York, New York 10004.
 
   
    We are a wholly-owned subsidiary of Sun Life Assurance Company of Canada
(U.S.) ("Sun Life of Canada (U.S.)"), a stock life insurance company
incorporated in Delaware and having its Executive Office at One Sun Life
Executive Park, Wellesley Hills, Massachusetts 02481. Sun Life of Canada (U.S.)
is an indirect wholly-owned subsidiary of Sun Life Assurance Company of Canada,
150 King Street West, Toronto, Ontario, Canada, a mutual life insurance company
incorporated in Canada in 1865.
    
 
THE VARIABLE ACCOUNT
 
   
    We established the Variable Account as a separate account of the Company on
December 3, 1984, pursuant to a resolution of the Company's Board of Directors.
The Variable Account meets the definition of a separate account under the
federal securities laws and is registered with the Securities and Exchange
Commission as a unit investment trust under the Investment Company Act of 1940.
    
 
   
    Under New York insurance law, and under the Contracts, the income, gains or
losses of the Variable Account are credited to or charged against the assets of
the Variable Account, without regard to the other income, gains or losses of the
Company. Although the assets maintained in the Variable Account will not be
charged with any liabilities arising out of any other business conducted by the
Company, all obligations arising under the Contracts, including the promise to
make annuity payments, are general corporate obligations of the Company.
    
 
    The assets of the Variable Account are divided into Sub-Accounts. Each
Sub-Account invests exclusively in shares of a specific series of the Series
Fund described below.
 
   
    In addition to the Contracts, we issue other variable annuity contracts
participating in the Variable Account.
    
 
                                       8
<PAGE>
THE SERIES FUND
 
    The Series Fund is an open-end management investment company registered
under the Investment Company Act of 1940. Our affiliate, Massachusetts Financial
Services Company ("MFS"), serves as the investment adviser to the Series Fund.
 
    All amounts allocated to the Variable Account will be used to purchase
shares of the Series Fund at their net asset value as you designate. Any and all
distributions made by the Series Fund with respect to the shares held by the
Variable Account will be reinvested to purchase additional shares at their net
asset value. We will make deductions from the Variable Account for cash
withdrawals, annuity payments, death benefits, administrative charges, Contract
charges against the assets of the Variable Account for the assumption of
mortality and expense risks and distribution expenses and any applicable taxes,
in effect, by redeeming the number of Series Fund shares, at their net asset
value, equal in total value to the amount to be deducted. The Variable Account
will be fully invested in Series Fund shares at all times.
 
   
    The Series Fund is composed of 26 independent portfolios of securities, each
of which has separate investment objectives and policies. Shares of the Series
Fund are issued in 26 series, each corresponding to one of the portfolios. The
Contracts provide for investment in shares of the 7 series of the Series Fund.
The investment objectives of each of the 7 available series of the Series Fund
are summarized below.
    
 
    (1) MONEY MARKET SERIES ("MMS") will seek maximum current income to the
extent consistent with stability of principal by investing exclusively in money
market instruments maturing in less than 13 months. An investment in this series
is neither insured nor guaranteed by the U.S. Government. There can be no
assurance that this series will be able to maintain a stable net asset value of
$1.00 per share.
 
    (2) HIGH YIELD SERIES ("HYS") will seek high current income and capital
appreciation by investing primarily in fixed income securities of U.S. and
foreign issuers which may be in the lower rated categories or unrated (commonly
known as "junk bonds") and which may include equity features. The series may
invest up to 100% of its net assets in these securities, which generally involve
greater risks, including volatility of price, risk to principal and income,
default risks, and less liquidity, than securities in the higher rated
categories. Any person contemplating allocating Purchase Payments to the
Sub-Account investing in shares of the High Yield Series should review the risk
disclosure in the Series Fund prospectus carefully and consider the investment
risks involved.
 
    (3) CAPITAL APPRECIATION SERIES ("CAS") will seek capital appreciation by
investing in securities of all types, with a major emphasis on common stocks.
 
   
    (4) GOVERNMENT SECURITIES SERIES ("GSS") will seek current income and
preservation of capital by investing in U.S. Government and U.S.
Government-related securities.
    
 
    (5) WORLD GOVERNMENTS SERIES ("WGS") will seek moderate current income and
preservation and growth of capital by investing in a portfolio of U.S. and
Foreign Government Securities.
 
    (6) TOTAL RETURN SERIES ("TRS") will seek primarily to obtain above-average
income (compared to a portfolio entirely invested in equity securities)
consistent with prudent employment of capital. Its secondary objective is to
take advantage of opportunities for growth of capital and income. Assets will be
allocated and reallocated from time to time between money market, fixed income
and equity securities. Under normal market conditions, at least 25% of the Total
Return Series' assets will be invested in fixed income securities and at least
40% and no more than 75% of its assets will be invested in equity securities.
 
    (7) MANAGED SECTORS SERIES ("MSS") will seek capital appreciation by varying
the weighting of its portfolio of common stocks among certain industry sectors.
Dividend income, if any, is incidental to its objective of capital appreciation.
 
                                       9

    Shares of the Series Fund are available exclusively to separate accounts
established by the Company and Sun Life of Canada (U.S.) to fund benefits under
variable life insurance and variable annuity products. Certain risks involved in
funding benefits under both life insurance and annuity contracts are discussed
in the Series Fund prospectus under the caption "Management of the Series Fund."
 
   
    More detailed information may be found in the current prospectus of the
Series Fund and the Series Fund's statement of additional information. A
prospectus for the Series Fund must accompany this Prospectus and you should
read it together with this Prospectus.
    
 
THE FIXED ACCOUNT
 
    See Appendix A to the Statement of Additional Information for a description
of the Fixed Account.
 
                     PURCHASE PAYMENTS AND CONTRACT VALUES
                           DURING ACCUMULATION PHASE
 
PURCHASE PAYMENTS
 
   
    You must send all Purchase Payments to us at our Annuity Service Mailing
Address. Unless you have surrendered the Contract, you may make Purchase
Payments at any time during the life of the Annuitant and before the Annuity
Commencement Date. Purchase Payments may be made annually, semi-annually,
quarterly, monthly, or on any other frequency acceptable to us. The amount of
Purchase Payments may vary; however, Purchase Payments must total at least $300
for the first Contract Year, and each Purchase Payment must be at least $25. In
addition, our approval is required before we will accept a Purchase Payment if
the value of your Accumulation Account exceeds $1,000,000 or if the Purchase
Payment would cause the value of your Accumulation Account to exceed $1,000,000.
    
 
   
    Your completed application forms, together with the initial Purchase
Payment, are forwarded to us. Upon acceptance, we issue the Contract to you and
credit the initial Purchase Payment to the Contract in the form of Accumulation
Units. We will credit the initial Purchase Payment within 2 business days after
we receive your completed application. If your application is incomplete, we may
retain the Purchase Payment for up to 5 business days while we try to complete
the application. If we cannot complete the application within 5 business days,
we will notify you of the reason for the delay and will return the Purchase
Payment immediately, unless you specifically consent to our retaining the
Purchase Payment until we can complete the application. Once the application is
completed, we will credit the Purchase Payment within 2 business days. We will
credit all subsequent Purchase Payments using the Accumulation Unit values for
the Valuation Period during which we receive the Purchase Payment.
    
 
    We will establish an Accumulation Account for each Contract. Your
Accumulation Account value for any Valuation Period is equal to the variable
accumulation value, if any, plus the fixed accumulation value, if any, for that
Valuation Period. The variable accumulation value is equal to the sum of the
value of all Variable Accumulation Units credited to your Accumulation Account.
 
    We will allocate each net Purchase Payment to either the Fixed Account or to
Sub-Accounts of the Variable Account or to both Sub-Accounts and the Fixed
Account in accordance with the allocation factors you have specified in the
application or as subsequently changed. When we receive a Purchase Payment, we
will credit all of that portion, if any, of the net Purchase Payment to be
allocated to the Sub-Accounts to the Accumulation Account in the form of
Variable Accumulation Units. The number of Variable Accumulation Units we credit
is determined by dividing the dollar amount allocated to the Sub-Account by the
Variable Accumulation Unit value for that Sub-Account for the Valuation Period
during which we receive the Purchase Payment.
 
    We established the Variable Accumulation Unit value for each Sub-Account at
$10.00 for the first Valuation Period of that Sub-Account. We determine the
Variable Accumulation Unit value for any subsequent Valuation Period as follows:
we multiply the Variable Accumulation Unit value for the immediately preceding
Valuation Period by the appropriate Net Investment Factor for the subsequent
Valuation Period. The Variable Accumulation Unit value for each Sub-Account for
any Valuation Period
 
                                       10
<PAGE>
is determined at the end of the Valuation Period and may increase, decrease or
remain constant from Valuation Period to Valuation Period, depending on the
investment performance of the series of the Series Fund in which the Sub-Account
is invested, and the expenses and charges deducted from the Variable Account.
 
NET INVESTMENT FACTOR
 
    The Net Investment Factor is an index applied to measure the investment
performance of a Sub-Account from one Valuation Period to the next. The Net
Investment Factor may be greater or less than or equal to one; therefore, the
value of a Variable Accumulation Unit may increase, decrease or remain the same.
 
   
    The Net Investment Factor for any Sub-Account for any Valuation Period is
determined by dividing (a) by (b) and then subtracting (c) from the result,
where:
    
 
        (a) is the net result of:
 
            (1) the net asset value of a Series Fund share held in the
                Sub-Account determined as of the end of the Valuation Period,
                plus
 
            (2) the per share amount of any dividend or other distribution
                declared on the Series Fund shares held in the Sub-Account if
                the "ex dividend" date occurs during the Valuation Period, plus
                or minus
 
   
            (3) a per share credit or charge with respect to any taxes paid or
                reserved for by the Company during the Valuation Period which we
                determine to be attributable to the operation of the Sub-Account
                (no federal income taxes are applicable under present law);
    
 
        (b) is the net asset value of a Series Fund share held in the
            Sub-Account determined as of the end of the preceding Valuation
            Period; and
 
        (c) is the risk charge factor we determine for the Valuation Period to
            reflect the charge for assuming the mortality and expense risks.
 
TRANSFERS
 
    During the Accumulation Phase, you may transfer all or part of the value of
your Accumulation Account to one or more Sub-Accounts then available or to the
Fixed Account, or to any combination of these options. We make these transfers
by converting the value of the Accumulation Units you wish to transfer into
Variable Accumulation Units of Sub-Accounts and/or Fixed Accumulation Units of
the same aggregate value, as you choose. These transfers are subject to the
following conditions:
 
        (1) you may make transfers involving Fixed Accumulation Units only
            during the 45 day period before and the 45 day period after each
            Contract Anniversary;
 
        (2) you may not make more than 12 transfers in any Contract Year; and
 
        (3) the amount transferred may not be less than $1,000 unless you are
            transferring your entire balance in the Fixed Account or a
            Sub-Account.
 
    In addition, these transfers will be subject to such terms and conditions as
the Series Fund may impose. We will make these transfers using the Accumulation
Unit values for the Valuation Period during which we receive the request for
transfer. Transfers may be made pursuant to telephoned instructions.
 
                                CASH WITHDRAWALS
 
   
    At any time during the Accumulation Phase, you may withdraw in cash all or
any portion of the value of your Accumulation Account. Withdrawals may be
subject to a withdrawal charge (see
    
 
                                       11
<PAGE>
   
"Withdrawal Charges"). Withdrawals also may have adverse federal income tax
consequences, including a 10% penalty tax (see "Federal Tax Status"). In
addition, if you own a Qualified Contract you should check the terms of your
retirement plan for restrictions on withdrawals.
    
 
    Your withdrawal request will be effective on the date we receive it. If you
request a withdrawal of more than $5,000 we may require a signature guarantee.
Your request must specify the amount you wish to withdraw. For a partial
withdrawal you may specify the amount you want withdrawn from the Fixed Account
and/or each Sub-Account to which your Accumulation Account is allocated. If you
do not so specify, we will deduct the total amount you request pro rata based on
your allocations at the end of the Valuation Period during which we receive your
request.
 
    If you request a full withdrawal, we will pay you the value of your
Accumulation Account at the end of the Valuation Period during which we receive
your request, minus the contract maintenance charge for the current Contract
Year and any applicable withdrawal charge. If you request a partial withdrawal,
we will pay you the amount you request less any applicable withdrawal charge and
reduce the value of your Accumulation Account by deducting the amount requested.
If you request a partial withdrawal that would result in the value of your
Accumulation Account being reduced to an amount less than the contract
maintenance charge for the current Contract Year, we will treat it as a request
for a full withdrawal.
 
    We will pay you the applicable amount of any full or partial withdrawal
within seven days after we receive your withdrawal request, except in cases
where we are permitted to defer payment under the Investment Company Act of 1940
and applicable state insurance law. Currently, we may defer payment of amounts
you withdraw only for following periods:
 
    - when the New York Stock Exchange is closed except weekends and holidays or
      when trading on the New York Stock Exchange is restricted;
 
    - when it is not reasonably practical to dispose of securities held by the
      Series Fund or to determine the value of the net assets of the Series
      Fund, because an emergency exists; or
 
    - when an SEC order permits us to defer payment for the protection of
      securities holders.
 
SECTION 403(b) ANNUITIES
 
   
    The Internal Revenue Code imposes restrictions on cash withdrawals from
contracts used with Section 403(b) Annuities. In order for a Contract to receive
tax deferred treatment, the Contract must provide that cash withdrawals of
amounts attributable to salary reduction contributions (other than withdrawals
of Accumulation Account value as of December 31, 1988 ("Pre-1989 Account
Value")) may be made only when the Owner attains age 59 1/2, separates from
service with the employer, dies or becomes disabled (within the meaning of
Section 72(m)(7) of the Code). These restrictions apply to any growth or
interest on or after January 1, 1989 on Pre-1989 Account Value, salary reduction
contributions made on or after January 1, 1989, and any growth or interest on
such contributions ("Restricted Account Value").
    
 
    Withdrawals of Restricted Account Value are also permitted in cases of
financial hardship, but only to the extent of contributions; earnings on
contributions cannot be withdrawn for hardship reasons. While specific rules
defining hardship have not been issued by the Internal Revenue Service, it is
expected that to qualify for a hardship distribution, the Owner must have an
immediate and heavy bona fide financial need and lack other resources reasonably
available to satisfy the need. Hardship withdrawals (as well as certain other
premature withdrawals) will be subject to a 10% tax penalty, in addition to any
withdrawal charge applicable under the Contract (see "Federal Tax Status").
Under certain circumstances, the 10% tax penalty will not apply to withdrawals
to pay medical expenses.
 
    Under the terms of a particular Section 403(b) plan, you may be entitled to
transfer all or a portion of the Accumulation Account value to one or more
alternative funding options. You should consult the documents governing their
plan and the person who administers such plan for information as to such
investment alternatives.

distributions from Qualified Contracts (including Section 403(b) annuities), see
"Federal Tax Status."
    
 
                                 DEATH BENEFIT
 
   
    If the Annuitant dies before the Annuity Commencement Date, we will pay a
death benefit to your Beneficiary. If the Annuitant dies on or after the Annuity
Commencement Date, we will not pay a death benefit, except as may be provided
under the annuity option elected.
    
 
   
    You select the Beneficiary in your Contract application. You may change your
Beneficiary at any time by sending us written notice on our required form,
unless you previously made an irrevocable Beneficiary designation. A new
Beneficiary designation is not effective until we record the change. If your
designated Beneficiary is not living on the date of death of the Annuitant, we
will pay the death benefit in one lump sum to you or, if you are the Annuitant,
to your estate.
    
 
   
    During the lifetime of the Annuitant and before the Annuity Commencement
Date, you may elect to have the death benefit payable under one or more of our
annuity options listed under "Annuity Provisions", for the Beneficiary as Payee.
If you have not elected a method of settlement of the death benefit that is in
effect on the date of death of the Annuitant, the Beneficiary may elect to
receive the death benefit in the form of either a cash payment or one or more of
our annuity options. If we do not receive an election by the Beneficiary within
60 days after the date we receive Due Proof of Death of the Annuitant and any
required release or consent, the Beneficiary will be deemed to have elected a
cash payment as of the last day of the 60 day period.
    
 
    In all cases, no Owner or Beneficiary will be entitled to exercise any
rights that would adversely affect the treatment of the Contract as an annuity
contract under the Internal Revenue Code (see "Other Contractual
Provisions--Death of Owner").
 
PAYMENT OF DEATH BENEFIT
 
   
    If the death benefit is to be paid in cash to the Beneficiary, we will make
payment within 7 days of the date the election becomes effective or is deemed to
become effective, except as we may be permitted to defer such payment in
accordance with the Investment Company Act of 1940 under the circumstances
described in this Prospectus under "Cash Withdrawals." If the death benefit is
to be paid in one lump sum to you (or to your estate if you are the Annuitant),
we will make payment within 7 days of the date we receive Due Proof of Death of
the Annuitant, the Owner and/or the Beneficiary, as applicable. If the death
benefit is to be paid under one or more of our annuity options, the Annuity
Commencement Date will be the first day of the second calendar month following
the effective date or the deemed effective date of the election, and we will
maintain your Accumulation Account in effect until the Annuity Commencement
Date. You or your Beneficiary, as the case may be, may elect an Annuity
Commencement Date later than that described above provided that such date is (a)
the first day of a calendar month, and (b) not later than the first day of the
first month following the 85th birthday of you or your Beneficiary, as
applicable, unless otherwise restricted (in the case of a Qualified Contract) by
the particular retirement plan or by applicable law (see "Annuity Commencement
Date").
    
 
AMOUNT OF DEATH BENEFIT
 
    The death benefit is equal to the greatest of:
 
    (1) the value of your Accumulation Account;
 
    (2) the total Purchase Payments made under the Contract reduced by all
        withdrawals;
 
    (3) the value of your Accumulation Account on the fifth Contract
        Anniversary, adjusted for any Purchase Payments or cash withdrawal
        payments made and Contract charges assessed after the fifth Contract
        Anniversary.
 
                                       13
<PAGE>
   
    To determine the amount of the death benefit under (1) above, we will use
Accumulation Values for the Valuation Period during which we receive Due Proof
of Death of the Annuitant if you have elected settlement under one or more of
the annuity options; if no election by you is in effect, we will use either the
values for the Valuation Period during which an election by the Beneficiary
becomes or is deemed effective or, if the death benefit is to be paid in one sum
to you or your estate, the values for the Valuation Period during which we
receive Due Proof of Death of both the Annuitant and the designated Beneficiary.
    
 
                                CONTRACT CHARGES
 
    We will assess contract charges under the Contracts as follows:
 
CONTRACT MAINTENANCE CHARGE
 
    We deduct an annual contract maintenance charge of $30 as partial
reimbursement for administrative expenses relating to the issuance and
maintenance of the Contract. Prior to the Annuity Commencement Date, we deduct
this charge on each Contract Anniversary. We also deduct this charge on
surrender of the Contract for full value on a date other than the Contract
Anniversary. We deduct the contract maintenance charge in equal amounts from the
Fixed Account and each Sub-Account in which you have Accumulation Units at the
time of the deduction.
 
   
    On the Annuity Commencement Date we will reduce the value of your
Accumulation Account by the proportionate amount of the contract maintenance
charge to reflect the time elapsed between the last Contract Anniversary and the
day before the Annuity Commencement Date. After the Annuity Commencement Date,
we will deduct the contract maintenance charge pro rata from each annuity
payment made during the year.
    
 
   
    We will not increase the amount of the contract maintenance charge. We
reserve the right to reduce the amount of the contract maintenance charge for
groups of participants with individual Contracts under an employer's retirement
program in situations in which the size of the group and established
administrative efficiencies contribute to a reduction in administrative
expenses.
    
 
MORTALITY AND EXPENSE RISK CHARGE
 
    We assume the risk that Annuitants may live for a longer period of time than
we have estimated in establishing the guaranteed annuity rates incorporated into
the Contract and the risk that administrative charges assessed under the
Contracts may be insufficient to cover our actual administrative expenses.
 
   
    For assuming these risks, we make a deduction from the Variable Account at
the end of each Valuation Period both during the Accumulation Phase and after
annuity payments begin at an effective annual rate of 1.30%. We may change the
rate of this deduction annually, but it will not exceed 1.30% on an annual
basis. If the deduction is insufficient to cover the actual cost of the
mortality and expense risk undertaking, we will bear the loss. Conversely, if
the deduction proves more than sufficient, the excess would be profit to us and
would be available for any proper corporate purpose including, among other
things, payment of distribution expenses. If the withdrawal charges described
below prove insufficient to cover expenses associated with the distribution of
the Contracts, we will meet the deficiency from our general corporate funds,
which may include amounts derived from the mortality and expense risk charges.
    
 
   
    For the year ended December 31, 1998 mortality and expense risk charges
imposed under the Contracts and mortality and expense risk charges and
distribution expense charges imposed under other contracts participating in the
Variable Account were the only expenses of the Variable Account.
    
 
WITHDRAWAL CHARGES
 
    We do not deduct a sales charge from Purchase Payments. However, we will
impose a withdrawal charge (i.e., a contingent deferred sales charge) on certain
amounts you withdraw as reimbursement for certain expenses relating to the
distribution of the Contracts, including commissions, costs of preparation of
sales literature and other promotional costs and acquisition expenses.

    You may withdraw a portion of your Accumulation Account value each year
before incurring the withdrawal charge, and after we have held a Purchase
Payment for 5 years you may withdraw it free of any withdrawal charge. In
addition, we do not impose a withdrawal charge upon annuitization or upon the
transfer of Accumulation Account values among the Sub-Accounts or between the
Sub-Accounts and the Fixed Account.
    
 
    We do not impose the withdrawal charge with respect to a Contract
established for the personal account of an employee of the Company or of any of
its affiliates, or of a licensed insurance agent engaged in distributing the
Contracts.
 
    All other full or partial withdrawals are subject to a withdrawal charge
equal to 5% of the amount withdrawn that is subject to the charge. We will apply
the charge as follows:
 
   
    (1) Old Payments, New Payments and accumulated value: In a given Contract
Year, "New Payments" are Payments you have made in that Contract Year or in the
4 previous Contract Years; "Old Payments" are all Purchase Payments made before
the previous 4 Contract Years; and the remainder of your Accumulation Account
value--that is, the value of your Accumulation Account minus the total of Old
Payments and New Payments--is called the "accumulated value."
    
 
   
    (2) Order of withdrawal: When you make a partial withdrawal or surrender
your Contract, we consider the oldest Payment not previously withdrawn to be
withdrawn first, then the next oldest, and so forth. Once all Old Payments and
New Payments have been withdrawn, additional amounts withdrawn will be
attributed to accumulated value.
    
 
    (3) Free withdrawal amount: In any Contract Year, you may withdraw the
following amount before we impose a withdrawal charge: (a) any Old Payments you
have not previously withdrawn, and (b) 10% of any New Payments, whether or not
these New Payments have been previously withdrawn
 
   
    (4) Amount subject to withdrawal charge: We will impose the withdrawal
charge on the excess, if any, of (a) Old Payments and New Payments being
withdrawn over (b) the remaining free withdrawal amount at the time of the
withdrawal. We do not impose the withdrawal charge on amounts attributed to
accumulated value.
    
 
   
    Aggregate withdrawal charges assessed against a Contract will never exceed
5% of the total amount of Purchase Payments made under the Contract. (See
Appendix C to the Statement of Additional Information for examples of
withdrawals and withdrawal charges.)
    
 
PREMIUM TAXES
 
    We will make a deduction, when applicable, for premium taxes or similar
state or local taxes. Currently, no premium taxes are applicable in the State of
New York; however, if you or the Payee are a resident of a state other than New
York, a premium tax ranging from 0% to 3.5% may be assessed, depending on the
state of residence. It is currently our policy to deduct the tax from the amount
applied to provide an annuity at the time annuity payments commence. However, we
reserve the right to deduct such taxes on or after the date they are incurred.
 
CHARGES OF THE SERIES FUND
 
    The Variable Account purchases shares of the Series Fund at net asset value.
The net asset value of these shares reflects investment management fees and
expenses (including, but not limited to, compensation of trustees, governmental
expenses, interest charges, taxes, fees of auditors, legal counsel, transfer
agent and custodian, transactional expenses and brokerage commissions) already
deducted from the assets of the Series Fund. These fees and expenses are more
fully described in the Series Fund's prospectus and the Statement of Additional
Information.

                               ANNUITY PROVISIONS
 
ANNUITY COMMENCEMENT DATE
 
    We begin making annuity payments under a Contract on the Annuity
Commencement Date, which you select in your Contract application. You may change
the Annuity Commencement Date from time to time as provided in the Contract. The
Annuity Commencement Date must be the first day of a month and not later than
the first day of the first month following the Annuitant's 85th birthday. Any
new Annuity Commencement Date must be at least 30 days after we receive notice
of the change.
 
   
    For Qualified Contracts, there may be other restrictions on your selection
of the Annuity Commencement Date imposed by the particular retirement plan or by
applicable law. For example, in most situations, current law requires that the
Annuity Commencement Date under a Qualified Contract be no later than April 1
following the year the Annuitant reaches age 70 1/2 (or, for Qualified Contracts
other than IRAs, no later than April 1 following the year the Annuitant retires,
if later than the year the Annuitant reaches age 70 1/2). The Annuity
Commencement Date may also be changed by an election of an annuity option, as
described under "Death Benefit." Please refer to the terms of your plan for
additional restrictions.
    
 
    On the Annuity Commencement Date, we will cancel your Accumulation Account
and apply its adjusted value to provide an annuity. The adjusted value will be
equal to the value of the Accumulation Account for the Valuation Period which
ends immediately before the Annuity Commencement Date, reduced by any applicable
premium or similar taxes and a proportionate amount of the contract maintenance
charge (see "Contract Maintenance Charge"). NO CASH WITHDRAWALS WILL BE
PERMITTED AFTER THE ANNUITY COMMENCEMENT DATE EXCEPT AS MAY BE AVAILABLE UNDER
THE ANNUITY OPTION ELECTED.
 
ANNUITY OPTIONS
 
   
    During the lifetime of the Annuitant and prior to the Annuity Commencement
Date, you may elect one or more of the annuity options described below or such
other settlement option as we may agree to for the Annuitant as Payee, except as
restricted by the particular retirement plan or any applicable legislation.
These annuity options may also be elected by you or the Beneficiary, as provided
under "Death Benefit."
    
 
   
    You may not change any election after 30 days before the Annuity
Commencement Date, and no change of annuity option is permitted after the
Annuity Commencement Date. If no election is in effect on the 30th day before
the Annuity Commencement Date, we will deem Annuity Option B, for a Life Annuity
with 120 monthly payments certain, to have been elected.
    
 
    Any election may specify the proportion of the adjusted value of your
Accumulation Account to be applied to the Fixed Account and the Sub-Accounts. If
the election does not so specify, then the portion of the adjusted value of the
Accumulation Account to be applied to the Fixed Account and the Sub-Accounts
will be determined on a pro rata basis from the composition of the Accumulation
Account on the Annuity Commencement Date.
 
    Annuity Options A, B and C are available to provide either a Fixed Annuity
or a Variable Annuity. Annuity Options D and E are available only to provide a
Fixed Annuity.
 
    Annuity Option A. Life Annuity: We make monthly payments during the lifetime
of the Payee. This option offers a higher level of monthly payments than Annuity
Options B or C because we do not make further payments after the death of the
Payee, and there is no provision for a death benefit payable to a Beneficiary.
 
   
    Annuity Option B. Life Annuity with 60, 120, 180 or 240 Monthly Payments
Certain: We make monthly payments during the lifetime of the Payee and in any
event for 60, 120, 180 or 240 months certain, as elected. The election of a
longer period certain results in smaller monthly payments than would be the case
if a shorter period certain was elected.
    
 
                                       16
<PAGE>
    Annuity Option C. Joint and Survivor Annuity: We make monthly payments
during the joint lifetime of the Payee and the designated second person and
during the lifetime of the survivor. During the lifetime of the survivor,
variable monthly payments, if any, will be determined using the percentage
chosen at the time of the election of this option of the number of each type of
Annuity Unit credited to the Contract and each fixed monthly payment, if any,
will be equal to the same percentage of the fixed monthly payment payable during
the joint lifetime of the Payee and the designated second person.
 
   
    *Annuity Option D. Fixed Payments for a Specified Period Certain: We make
fixed monthly payments for a specified period of time (at least 5 years but not
exceeding 30 years), as elected.
    
 
   
    *Annuity Option E. Fixed Payments: We will hold the amount applied to
provide fixed payments in accordance with this option at interest. We will make
fixed payments in such amounts and at such times (at least over a period of 5
years) as we have agreed upon and will continue until the amount we hold with
interest is exhausted. We will credit interest yearly on the amount remaining
unpaid at a rate which we shall determine from time to time but which shall not
be less than 4% per year compounded annually. We may change the rate so
determined at any time; however, the rate may not be reduced more frequently
than once during each calendar year.
    
 
DETERMINATION OF ANNUITY PAYMENTS
 
   
    We will determine the dollar amount of the first Variable Annuity payment in
accordance with the annuity payment rates found in the Contract, which are based
on an assumed interest rate of 4% per year. We determine all Variable Annuity
payments other than the first by means of Annuity Units credited to the
Contract. The number of Annuity Units to be credited in respect of a particular
Sub-Account is determined by dividing the portion of the first Variable Annuity
payment attributable to that Sub-Account by the Annuity Unit value of that
Sub-Account for the Valuation Period that ends immediately before the Annuity
Commencement Date. The number of Annuity Units of each Sub-Account credited to
the Contract then remains fixed, unless an exchange of Annuity Units is made as
described below. The dollar amount of each Variable Annuity payment after the
first may increase, decrease or remain constant, depending on the investment
performance of the Sub-Accounts.
    
 
    The Statement of Additional Information contains detailed disclosure
regarding the method of determining the amount of each Variable Annuity payment
and calculating the value of a Variable Annuity Unit, as well as hypothetical
examples of these calculations.
 
EXCHANGE OF VARIABLE ANNUITY UNITS
 
   
    After the Annuity Commencement Date, the Payee may exchange Variable Annuity
Units from one Sub-Account to another, up to a maximum of 12 such exchanges each
Contract Year. We calculate the number of new Variable Annuity Units so that the
dollar amount of an annuity payment made on the date of the exchange would be
unaffected by the fact of the exchange.
    
 
ANNUITY PAYMENT RATES
 
    The Contract contains annuity payment rates for each Annuity Option
described above. The rates show, for each $1,000 applied, the dollar amount of
(a) the first monthly Variable Annuity payment based on the assumed interest
rate of 4%, and (b) the monthly Fixed Annuity payment, when this payment is
based on the minimum guaranteed interest rate of 4% per year. The annuity
payment rates may vary according to the annuity option elected and the adjusted
age of the Payee.
 
   
    If net investment return of the Sub-Accounts was exactly equal to the
assumed interest rate of 4%, the amount of each Variable Annuity payment would
remain level. If a net investment return is greater than 4%, the amount of each
Variable Annuity payment would increase; conversely, if the net investment
return is less than 4%, the amount of each Variable Annuity payment would
decrease.
    
 
- ------------------------
* The election of this Annuity Option may result in the imposition of a penalty
tax.

                           OTHER CONTRACT PROVISIONS
 
OWNER
 
    As the Owner, you are entitled to exercise all Contract rights and
privileges without the consent of the Beneficiary or any other person. Such
rights and privileges may be exercised only during the lifetime of the Annuitant
and prior to the Annuity Commencement Date, except as otherwise provided in the
Contract. The Owner of a Non-Qualified Contract may change the ownership of the
Contract, subject to the provisions of the Contract, although such change may
result in the imposition of tax (see "Federal Tax Status--Taxation of Annuities
in General"). Transfer of ownership of a Qualified Contract is governed by the
laws and regulations applicable to the retirement or deferred compensation plan
for which the Contract was issued. Subject to the foregoing, a Qualified
Contract may not be sold, assigned, transferred, discounted or pledged as
collateral for a loan or as security for the performance of an obligation or for
any other purpose to any person other than the Company.
 
    Subject to the rights of an irrevocably designated Beneficiary, the Owner
may change or revoke the designation of a Beneficiary at any time while the
Annuitant is living.
 
DEATH OF OWNER
 
   
    If you are the Owner of a Non-Qualified Contract and you die before the
Annuitant and before the Annuity Commencement Date, your Accumulation Account
must be distributed to the Beneficiary, if then alive, either (1) within 5 years
after the date of your death, or (2) over some period not greater than the life
or expected life of the Beneficiary, with annuity payments beginning within one
year after the date of your death. The person named as Beneficiary shall be
considered the designated beneficiary for the purposes of Section 72(s) of the
Internal Revenue Code and if no person then living has been so named, then the
Annuitant shall automatically be the designated beneficiary for this purpose.
    
 
   
    These mandatory distribution requirements will not apply when the designated
Beneficiary is your spouse, if your spouse elects to continue the Contract in
his or her own name as Owner. If you were the Annuitant as well as the Owner,
your surviving spouse (if the designated Beneficiary) may elect to be named as
both Owner and Annuitant and continue the Contract; if your spouse does not make
that election, the death benefit provision of the Contract shall be controlling,
subject to the condition that any annuity option elected complies with the
Section 72(s) distribution requirements. In all other cases where the Owner and
the Annuitant are the same individual, the death benefit provision of the
Contract controls.
    
 
    If you are both the Owner and Annuitant and you die on or after the Annuity
Commencement Date and before the entire accumulation under the Contract has been
distributed, the remaining portion of such accumulation, if any, must be
distributed at least as rapidly as the method of distribution then in effect.
 
   
    In all cases, no Owner or Beneficiary shall be entitled to exercise any
rights that would adversely affect the treatment of the Contract as an annuity
contract under the Internal Revenue Code.
    
 
    Any distributions upon the death of the Owner of a Qualified Contract will
be subject to the laws and regulations governing the particular retirement or
deferred compensation plan in connection with which the Qualified Contract was
issued.
 
VOTING OF SERIES FUND SHARES
 
   
    We will vote Series Fund shares held by the Sub-Accounts at meetings of
shareholders of the Series Fund or in connection with similar solicitations, but
will follow voting instructions received from persons having the right to give
voting instructions. We will vote Series Fund shares for which no timely voting
instructions are received in the same proportion as the shares for which
instructions are received from persons having such voting rights. The Owner is
the person having the right to give voting instructions prior to the Annuity
Commencement Date. On or after the Annuity Commencement Date, the Payee is the
person having such voting rights.
    
 
                                       18
<PAGE>
    Owners of Contracts held pursuant to retirement plans may be subject to
other voting provisions of the particular retirement plan. Employees who
contribute to retirement plans which are funded by the Contracts are entitled to
instruct the Owners as to how to instruct the Company to vote the Series Fund
shares attributable to their contributions. Such plans may also provide the
additional extent, if any, to which the Owners shall follow voting instructions
of persons with rights under the plans.
 
    We will determine the number of particular Series Fund shares as to which
each such person is entitled to give instructions on a date not more than 90
days prior to each such meeting. Prior to the Annuity Commencement Date, we
determine that number by dividing the value of all of the Variable Accumulation
Units of the particular Sub-Account credited to the Contract's Accumulation
Account by the net asset value of one particular Series Fund share as of the
same date. On or after the Annuity Commencement Date, we determine the number of
particular Series Fund shares as to which such instructions may be given by a
Payee by dividing the reserve held by the Company in the particular Sub-Account
for the Contract by the net asset value of a particular Series Fund share as of
the same date.
 
SUBSTITUTED SECURITIES
 
   
    Shares of a particular series of the Series Fund may not always be available
for purchase by the Variable Account or we may decide that further investment in
any such shares is no longer appropriate in view of the purposes of the Variable
Account or in view of legal, regulatory or federal income tax restrictions. In
either event, shares of another series or shares of another registered open-end
investment company may be substituted both for Series Fund shares already
purchased by the Variable Account and as the security to be purchased in the
future, provided that these substitutions have been approved by the Securities
and Exchange Commission and the Superintendent of Insurance of the State of New
York. In the event of any substitution pursuant to this provision, we may make
appropriate endorsement to the Contract to reflect the substitution.
    
 
MODIFICATION
 
    Upon notice to you, or to the Payee during the annuity period, we may modify
the Contract, but only if such modification (i) is necessary to make the
Contract or the Variable Account comply with any law or regulation issued by a
governmental agency to which we are subject or (ii) is necessary to assure
continued qualification of the Contract under the Internal Revenue Code or other
federal or state laws relating to retirement annuities or annuity contracts or
(iii) is necessary to reflect a change in the operation of the Variable Account
or the Sub-Accounts or (iv) provides additional Variable Account and/ or fixed
accumulation options. In the event of any such modification, we may make
appropriate endorsement to the Contract to reflect such modification.
 
CHANGE IN OPERATION OF VARIABLE ACCOUNT
 
   
    At the Company's election and subject to the prior approval of the
Superintendent of Insurance of the State of New York and to any necessary vote
by persons having the right to give instructions with respect to the voting of
Series Fund shares held by the Sub-Accounts, the Variable Account may be
operated as a management company under the Investment Company Act of 1940 or it
may be deregistered under the Investment Company Act of 1940 in the event
registration is no longer required. Deregistration of the Variable Account
requires an order by the Securities and Exchange Commission. In the event of any
such change in the operation of the Variable Account, we may, subject to the
prior approval of the Superintendent of Insurance of the State of New York, make
appropriate endorsement to the Contract to reflect the change and take such
action as may be necessary and appropriate to effect the change.
    
 
                                       19
<PAGE>
SPLITTING UNITS
 
    We reserve the right to split or combine the value of Variable Accumulation
Units, Fixed Accumulation Units, Annuity Units or any of them. In effecting any
such change in unit values, strict equity will be preserved and no change will
have a material effect on the benefits or other provisions of the Contract.
 
                               FEDERAL TAX STATUS
 
INTRODUCTION
 
   
    The Contracts are designed for use in connection with retirement plans that
may or may not be qualified plans under Sections 401, 403 or 408 of the Internal
Revenue Code (the "Code"). The ultimate effect of federal income taxes may
depend upon the type of retirement plan for which the Contract is purchased and
a number of different factors. This discussion is general in nature, is based
upon the Company's understanding of current federal income tax laws, and is not
intended as tax advice. Congress has the power to enact legislation affecting
the tax treatment of annuity contracts, and such legislation could be applied
retroactively to Contracts purchased before the date of enactment. Any person
contemplating the purchase of a Contract should consult a qualified tax adviser.
THE COMPANY DOES NOT MAKE ANY GUARANTEE REGARDING THE FEDERAL, STATE OR LOCAL
TAX STATUS OF ANY CONTRACT OR ANY TRANSACTION INVOLVING A CONTRACT.
    
 
TAX TREATMENT OF THE COMPANY AND THE VARIABLE ACCOUNT
 
    The Company is taxed as a life insurance company under the Code. The
operations of the Variable Account are accounted for separately from other
operations of the Company for purposes of federal income taxation, but the
Variable Account is not taxable as a regulated investment company or otherwise
as an entity separate from the Company. The income of the Variable Account
(consisting primarily of interest, dividends and net capital gains) is not
taxable to the Company to the extent that it is applied to increase reserves
under contracts participating in the Variable Account.
 
TAXATION OF ANNUITIES IN GENERAL
 
    Purchase Payments made under Non-Qualified Contracts are not deductible from
the Owner's income for federal income tax purposes. Owners of Qualified
Contracts should consult a tax adviser regarding the tax treatment of Purchase
Payments.
 
    Generally, no taxes are imposed on the increase in the value of a Contract
held by an individual Owner until a distribution occurs, either as an annuity
payment or as a cash withdrawal or lump sum payment prior to the Annuity
Commencement Date. However, corporate Owners and other Owners that are not
natural persons are subject to current taxation on the annual increase in the
value of a Non-Qualified Contract, unless the non-natural person holds the
Contract as agent for a natural person (such as where a bank or other entity
holds a Contract as trustee under a trust agreement). This current taxation of
annuities held by non-natural persons does not apply to earnings accumulated
under an immediate annuity, which the Code defines as a single premium contract
with an annuity commencement date within one year of the date of purchase.
 
    A partial cash withdrawal (i.e., a withdrawal of less than the entire value
of the Contract's Accumulation Account) from a Non-Qualified Contract before the
Annuity Commencement Date is treated first as a withdrawal from the increase in
the Accumulation Account's value, rather than as a return of Purchase Payments.
The amount of the withdrawal allocable to this increase will be includible in
the Owner's income and subject to tax at ordinary income rates. If an individual
receives a loan under a Contract or if the Contract is assigned or pledged as
collateral for a loan, the amount borrowed from the Contract or the amount
assigned or pledged must be treated as if it were withdrawn from the Contract.
 
    In the case of annuity payments under a Non-Qualified Contract after the
Annuity Commencement Date, a portion of each payment is treated as a nontaxable
return of Purchase Payments. The
 
                                       20
<PAGE>
nontaxable portion is determined by applying to each annuity payment an
"exclusion ratio," which, in general, is the ratio that the total amount the
Owner paid for the Contract bears to the Payee's expected return under the
Contract. The remainder of the payment is taxable at ordinary income rates.
 
    The total amount that a Payee may exclude from income through application of
the "exclusion ratio" is limited to the amount the Owner paid for the Contract.
If the Annuitant survives for his full life expectancy, so that the Payee
recovers the entire amount paid for the Contract, any subsequent annuity
payments will be fully taxable as income. Conversely, if the Annuitant dies
before the Payee recovers the entire amount paid, the Payee will be allowed a
deduction for the amount of unrecovered Purchase Payments.
 
    Taxable cash withdrawals and lump sum payments from Non-Qualified Contracts
may be subject to a penalty tax equal to 10% of the amount treated as taxable
income. This 10% penalty also may apply to certain annuity payments. This
penalty will not apply in certain circumstances (such as where the distribution
is made upon the death of the Owner). The withdrawal penalty also does not apply
to distributions under an immediate annuity (as defined above).
 
   
    In the case of a Qualified Contract, distributions generally are taxable and
distributions made prior to age 59 1/2 are subject to a 10% penalty tax,
although this penalty tax will not apply in certain circumstances. Certain
distributions, known as "eligible rollover distributions," if rolled over to
certain other qualified retirement plans (either directly or after being
distributed to the Payee), are not taxable until distributed from the plan to
which they are rolled over. In general, an eligible rollover distribution is any
taxable distribution other than a hardship distribution or a distribution that
is part of a series of payments made for life or for a specified period of ten
years or more. Owners, Annuitants, Payees and Beneficiaries should seek
qualified advice about the tax consequences of distributions, withdrawals,
payments and rollovers under the retirement plans in connection with which the
Contracts are purchased.
    
 
    If the Owner of a Non-Qualified Contract dies, the value of the Contract
generally must be distributed within a specified period (see "Other Contractual
Provisions--Death of Owner"). For Contracts owned by non-natural persons, a
change in the Annuitant is treated as the death of the Owner.
 
    A purchaser of a Qualified Contract should refer to the terms of the
applicable retirement plan and consult a tax adviser regarding distribution
requirements upon the death of the Owner.
 
    A transfer of a Non-Qualified Contract by gift (other than to the Owner's
spouse) is treated as the receipt by the Owner of income in an amount equal to
the value of the Contract's Accumulation Account minus the total amount paid for
the Contract.
 
    The Company will withhold and remit to the U.S. Government a part of the
taxable portion of each distribution made under a Non-Qualified Contract or
under a Qualified Contract issued for use with an individual retirement account,
unless the Owner or Payee provides his or her taxpayer identification number to
the Company and notifies the Company (in the manner prescribed) before the time
of the distribution that he or she chooses not to have any amounts withheld.
 
    In the case of distributions from a Qualified Contract (other than
distributions from a Contract issued for use with an individual retirement
account), the Company or the plan administrator must withhold and remit to the
U.S. Government 20% of each distribution that is an eligible rollover
distribution (as defined above) unless the Owner or Payee elects to make a
direct rollover of the distribution to another qualified retirement plan that is
eligible to receive the rollover. If a distribution from a Qualified Contract is
not an eligible rollover distribution, then the Owner or Payee can choose not to
have amounts withheld as described above for Non-Qualified Contracts and
Qualified Contracts issued for use with individual retirement accounts.
 
    Amounts withheld from any distribution may be credited against the Owner's
or Payee's federal income tax liability for the year of the distribution.
 
                                       21
<PAGE>
    The Internal Revenue Service has issued regulations that prescribe
investment diversification requirements for mutual fund series underlying
nonqualified variable contracts. Contracts that do not comply with these
regulations do not qualify as annuities for federal income tax purposes, and
therefore the annual increase in the value of such contracts is subject to
current taxation. The Company believes that each series of the Series Fund
complies with the regulations.
 
    The preamble to the regulations states that the Internal Revenue Service may
promulgate guidelines under which a variable contract will not be treated as an
annuity for tax purposes if the owner has excessive control over the investments
underlying the contract. It is not known whether such guidelines, if in fact
promulgated, would have retroactive effect. If guidelines are promulgated, the
Company will take any action (including modification of the Contract and/or the
Variable Account) necessary to comply with the guidelines.
 
   
    THE FOLLOWING INFORMATION SHOULD BE CONSIDERED ONLY WHEN AN IMMEDIATE
ANNUITY CONTRACT AND A DEFERRED ANNUITY CONTRACT ARE PURCHASED TOGETHER: THE
COMPANY UNDERSTANDS THAT THE TREASURY DEPARTMENT MIGHT RECONSIDER THE TAX
TREATMENT OF ANNUITY PAYMENTS UNDER AN IMMEDIATE ANNUITY CONTRACT (I.E., A
SINGLE PREMIUM CONTRACT WITH AN ANNUITY COMMENCEMENT DATE WITHIN ONE YEAR OF THE
DATE OF PURCHASE) PURCHASED TOGETHER WITH A DEFERRED ANNUITY CONTRACT. THE
COMPANY BELIEVES THAT ANY ADVERSE CHANGE IN EXISTING TAX TREATMENT OF SUCH
IMMEDIATE ANNUITY CONTRACTS IS LIKELY TO BE PROSPECTIVE, THAT IS, IT WOULD NOT
APPLY TO CONTRACTS ISSUED BEFORE SUCH A CHANGE IS ANNOUNCED. HOWEVER, THERE CAN
BE NO ASSURANCE THAT ANY SUCH CHANGE, IF ADOPTED, WOULD NOT BE APPLIED
RETROACTIVELY.
    
 
QUALIFIED RETIREMENT PLANS
 
   
    The Qualified Contracts are designed for use with the following types of
qualified retirement plans:
    
 
        (1) Pension and Profit-Sharing Plans established by business employers
    and certain associations, as permitted by Sections 401(a), 401(k) and 403(a)
    of the Code, including those purchasers who would have been covered under
    the rules governing old H.R. 10 (Keogh) Plans;
 
        (2) Tax-Sheltered Annuities established pursuant to the provisions of
    Section 403(b) of the Code for public school employees and employees of
    certain types of charitable, educational and scientific organizations
    specified in Section 501(c)(3) of the Code; and
 
        (3) Individual Retirement Annuities permitted by Sections 219 and 408 of
    the Code, including Simplified Employee Pension Plans established by
    employers pursuant to Section 408(k).
 
    The tax rules applicable to participants in such plans vary according to the
type of plan and its terms and conditions. Therefore, no attempt is made herein
to provide more than general information about the use of Qualified Contracts.
Participants in such plans as well as Owners, Annuitants, Payees and
Beneficiaries are cautioned that the rights of any person to any benefits under
these plans are subject to the terms and conditions of the plans themselves,
regardless of the terms and conditions of the Qualified Contracts. These terms
and conditions may include restrictions on, among other things, ownership,
transferability, assignability, contributions and distributions. The Company
will provide purchasers of Qualified Contracts used in connection with
Individual Retirement Annuities with such supplemental information as may be
required by the Internal Revenue Service or other appropriate agency. Any person
contemplating the purchase of a Qualified Contract should consult a qualified
tax adviser.
 
                              YEAR 2000 COMPLIANCE
 
   
    The Company's business, financial condition, and results of operations could
be materially and adversely affected by the failure of its systems and
applications (or those either provided or operated by third-parties) to properly
operate or manage dates beyond the year 1999. However, the Company has
investigated the nature and extent of the work necessary to render its computer
systems capable of processing beyond the turn of the century ("Year 2000
compliant"), and has made substantial progress toward achieving this goal,
including upgrading and/or replacing existing systems. As of December 31, 1998,
over 90% of the system components had been remediated, tested and certified
    
 
                                       22
<PAGE>
   
as Year 2000 compliant. The majority of the remaining components are in the
testing phase and are expected to be certified by March 31, 1999. While it is
believed that these efforts do involve substantial costs, the Company closely
monitors associated costs and continues to evaluate associated risks based on
actual testing. Based on available information, the Company believes that it
will be able to manage its total Year 2000 transition without a material adverse
effect on its business operations, financial condition, or results of
operations.
    
 
                         DISTRIBUTION OF THE CONTRACTS
 
   
    The Contracts will be sold by licensed insurance agents in the State of New
York. Such agents will be registered representatives of broker-dealers
registered under the Securities Exchange Act of 1934 who are members of the
National Association of Securities Dealers, Inc. The Contracts will be
distributed by Clarendon Insurance Agency, Inc., One Sun Life Executive Park,
Wellesley Hills, Massachusetts 02481, a wholly-owned subsidiary of Sun Life
Assurance Company of Canada (U.S.). Commissions and other distribution expenses
will be paid by the Company and will not be more than 6.31% of Purchase
Payments. Commissions will not be paid with respect to Contracts established for
the personal account of employees of the Company or any of its affiliates, or of
persons engaged in the distribution of the Contracts.
    
 
                               LEGAL PROCEEDINGS
 
    There are no pending legal proceedings affecting the Variable Account. We
are engaged in various kinds of routine litigation which, in management's
opinion, is not of material importance to the Company's total assets or material
with respect to the Variable Account.

                              GENERAL INFORMATION
 
THE COMPANY
 

    Sun Life Insurance and Annuity Company of New York (the "Company") is a
stock life insurance company incorporated under the laws of New York on May 25,
1983. Its Home Office is located at 80 Broad Street, New York, New York 10004.
The Company is a wholly-owned subsidiary of Sun Life Assurance Company of Canada
(U.S.) ("Sun Life of Canada (U.S.)"), a stock life insurance company
incorporated in Delaware and having its Executive Office at One Sun Life
Executive Park, Wellesley Hills, Massachusetts 02481. Sun Life of Canada (U.S.),
is an indirect wholly-owned subsidiary of Sun Life Assurance Company of Canada
("Sun Life (Canada)"), 150 King Street West, Toronto, Ontario, Canada, a mutual
life insurance company incorporated in Canada in 1865.

 
THE VARIABLE ACCOUNT
 

    Sun Life (N.Y.) Variable Account B (the "Variable Account") is a separate
account of the Company which meets the definition of a "separate account" under
the federal securities laws and which is registered with the Securities and
Exchange Commission as a unit investment trust under the Investment Company Act
of 1940.

 
THE FIXED ACCOUNT
 

    If the Owner elects to have Contract values accumulated on a fixed basis,
Purchase Payments are allocated to the Fixed Account. Because of exemptive and
exclusionary provisions, that part of the Contracts relating to the Fixed
Account is not registered under the Securities Act of 1933 ("1933 Act") and the
Fixed Account is not registered as an investment company under the Investment
Company Act of 1940 ("1940 Act"). Accordingly, neither the Fixed Account nor any
interests therein, are subject to the provisions or restrictions of the 1933 Act
or the 1940 Act, and the staff of the Securities and Exchange Commission has not
reviewed the disclosures in this Statement of Additional Information with
respect to that portion of the Contract relating to the Fixed Account. However,
disclosures regarding the fixed portion of the Contracts and the Fixed Account
may be subject to certain generally applicable provisions of the federal
securities laws relating to the accuracy and completeness of statements made
herein (see "A Word About the Fixed Account" in Appendix A).

 
                               ANNUITY PROVISIONS
 
DETERMINATION OF ANNUITY PAYMENTS
 
    On the Annuity Commencement Date the Contract's Accumulation Account will 
be cancelled and its adjusted value will be applied to provide a Variable 
Annuity or a Fixed Annuity or a combination of both. The adjusted value will 
be equal to the value of the Accumulation Account for the Valuation Period 
which ends immediately preceding the Annuity Commencement Date, reduced by 
any applicable premium taxes or similar taxes and a proportionate amount of 
the contract maintenance charge to reflect the time elapsed between the last 
Contract Anniversary and the day before the Annuity Commencement Date.
 

    The dollar amount of the first variable annuity payment will be 
determined in accordance with the annuity payment rates found in the 
Contract, which are based on an assumed interest rate of 4% per year. All 
variable annuity payments other than the first are determined by means of 
Annuity Units credited to the Contract. The number of Annuity Units to be 
credited in respect of a particular Sub-Account is determined by dividing 
that portion of the first variable annuity payment attributable to that 
Sub-Account by the Annuity Unit value of that Sub-Account for the Valuation 
Period which ends immediately preceding the Annuity Commencement Date. The 
number of Annuity Units of each particular Sub-Account credited to the 
Contract remains fixed, unless an exchange of Annuity Units is made, as 
described in the Prospectus. The dollar amount of each variable annuity 
payment after the first such payment may increase, decrease or remain 
constant, and is equal to the sum of the amounts determined by multiplying 
the number of Annuity Units of a particular Sub-Account credited to the 
Contract by the Annuity Unit value for the particular Sub-Account for the 
Valuation Period which ends immediately preceding the due date of each 
subsequent payment.

 
    For a description of fixed annuity payments, see Appendix A.
 
                                       2
<PAGE>
    For a hypothetical example of the calculation of a variable annuity payment,
see Appendix B.
 
ANNUITY UNIT VALUE
 

    The Annuity Unit value for each Sub-Account was established at $10.00 for
the first Valuation Period of the particular Sub-Account. The Annuity Unit value
for any subsequent Valuation Period is determined by multiplying the Annuity
Unit value for the immediately preceding Valuation Period by the appropriate Net
Investment Factor (See "Net Investment Factor" in the Prospectus) for the
current Valuation Period, and then multiplying that product by a factor to
neutralize the assumed interest rate of 4% per year used to establish the
annuity payment rates found in the Contract. The factor for a one day Valuation
Period is 0.99989255.

 
    For a hypothetical example of the calculation of the value of a Variable
Annuity Unit, see Appendix B.
 
                           OTHER CONTRACT PROVISIONS
 
OWNER AND CHANGE OF OWNERSHIP
 

    A Contract belongs to the Owner. All Contract rights and privileges may be
exercised by the Owner without the consent of the Beneficiary (other than an
irrevocably designated beneficiary) or any other person. Such rights and
privileges may be exercised only during the lifetime of the Annuitant and prior
to the Annuity Commencement Date, except as otherwise provided in the Contract.
The Annuitant becomes the Owner on and after the Annuity Commencement Date. The
Beneficiary becomes the Owner upon the death of the Annuitant. In some qualified
plans the Owner of the Contract is a trustee and the trust authorizes the
Annuitant/participant to exercise certain Contract rights and privileges.

 

    Ownership of a Qualified Contract may not be transferred except to: (1) the
Annuitant; (2) a trustee or successor trustee of a pension or profit sharing
trust which is qualified under Section 401 of the Internal Revenue Code; (3) the
employer of the Annuitant, provided that after transfer the Qualified Contract
is maintained under the terms of a retirement plan qualified under Section
403(a) of the Internal Revenue Code for the benefit of the Annuitant; (4) the
trustee of an individual retirement account plan qualified under Section 408 of
the Internal Revenue Code for the benefit of the Owner; or (5) as otherwise
permitted from time to time by laws and regulations governing the retirement or
deferred compensation plans for which a Qualified Contract may be issued.
Subject to the foregoing, a Qualified Contract may not be sold, assigned,
transferred, discounted or pledged as collateral for a loan or as security for
the performance of an obligation or for any other purpose to any person other
than the Company.

 
    The Owner of a Non-Qualified Contract may change the ownership of the
Contract during the lifetime of the Annuitant and prior to the Annuity
Commencement Date, although such change may result in the imposition of tax (see
"Federal Tax Status--Taxation of Annuities in General" in the Prospectus). A
change of ownership will not be binding upon the Company until written
notification is received by the Company. Once received by the Company the change
will be effective as of the date on which the request for change was signed by
the Owner but the change will be without prejudice to the Company on account of
any payment made or any action taken by the Company prior to receiving the
change. The Company may require that the signature of the Owner be guaranteed by
a member firm of the New York, American, Boston, Midwest, Philadelphia or
Pacific Stock Exchange, or by a commercial bank (not a savings bank) which is a
member of the Federal Deposit Insurance Corporation or, in certain cases, by a
member firm of the National Association of Securities Dealers, Inc. which has
entered into an appropriate agreement with the Company.
 
DESIGNATION AND CHANGE OF BENEFICIARY
 

    The Beneficiary designation contained in the Contract application will
remain in effect until changed. The interest of any Beneficiary is subject to
the particular Beneficiary surviving the Annuitant.

 
    Subject to the rights of an irrevocably designated Beneficiary, the Owner
may change or revoke the designation of a Beneficiary at any time while the
Annuitant is living by filing with the Company a written Beneficiary designation
or revocation in such form as the Company may require. The change or revocation
will not be binding upon the Company until it is received by the Company. When
it is so received the change or revocation will be effective as of the date on
which the Beneficiary designation or revocation was signed by the Owner.
 
                                       3
<PAGE>
CUSTODIAN
 

    The Company is Custodian of the assets of the Variable Account. The Company,
as Custodian, will purchase shares of a particular series of the Series Fund at
net asset value in connection with amounts allocated to the particular
Sub-Account in accordance with the instructions of the Owner and will redeem
Series Fund shares at net asset value for the purpose of meeting the contractual
obligations of the Variable Account, paying charges relative to the Variable
Account or making adjustments for annuity reserves held in the Variable Account.

 
                        ADMINISTRATION OF THE CONTRACTS
 

    The Company performs certain administrative functions relating to the 
Contracts and the Variable Account. These functions include, among other 
things, maintaining the books and records of the Variable Account and the 
Sub-Accounts, and maintaining records of the name, address, taxpayer 
identification number, Contract number, type of contract issued to each 
owner, the status of the Accumulation Account under each Contract, and other 
pertinent information necessary to the administration and operation of the 
Contracts. The Company has entered into service agreements with its parent, 
Sun Life Assurance Company of Canada (U.S.), and Sun Life Assurance Company 
of Canada under which the latter have agreed to provide the Company with 
certain services on a cost reimbursement basis. These services include, but 
are not limited to, accounting and investment services, systems support and 
development, pricing, product development, actuarial, legal and compliance 
functions, marketing services and staff training.

 
                         DISTRIBUTION OF THE CONTRACTS
 

    The offering of the Contracts is continuous. The Contracts are sold by 
licensed insurance agents in the State of New York. Such agents are 
registered representatives of broker-dealers registered under the Securities 
Exchange Act of 1934 who are members of the National Association of 
Securities Dealers, Inc. The Contracts are distributed by Clarendon Insurance 
Agency, Inc. ("Clarendon"), One Sun Life Executive Park, Wellesley Hills, 
Massachusetts 02481, a wholly-owned subsidiary of Sun Life Assurance Company 
of Canada (U.S.), the Company's parent company. Commissions and other 
distribution compensation will be paid by the Company and will not be more 
than 6.31% of Purchase Payments. Commissions will not be paid with respect to 
Contracts established for the personal account of employees of the Company or 
any of its affiliates, or of persons engaged in the distribution of the 
Contracts. During 1996, 1997 and 1998, approximately $56,000, $40,000, and 
$________, respectively, was paid to and retained by Clarendon in connection 
with the distribution of the Contracts.

- ---------

*From Date of Inception, as the lifetimes of these series are less than 10
years.

 
The length of the period and the last day of each period used in the above table
are set out in the table heading and in the footnotes above. The Average Annual
Total Return for each period was determined by finding the average annual
compounded rate of return over each period that would equate the initial amount
invested to the ending redeemable value for that period, in accordance with the
following formula:
 
                                        n
                                P(1 + T)  = ERV
 
<TABLE>
<C>        <C>        <S>
 Where: P      =      a hypothetical initial Purchase Payment of $1,000
        T      =      average annual total return for the period
        n      =      number of years
      ERV      =      redeemable value (as of the end of the period) of a
                      hypothetical $1,000 Purchase Payment made at the beginning of
                      the 1-year, 5-year, or 10-year period (or fractional portion
                      thereof)
</TABLE>
 
   The formula assumes that: 1) all recurring fees have been deducted from the
   Contract's Accumulation Account; 2) all applicable non-recurring Contract
   charges are deducted at the end of the period; and 3) there will be a full
   surrender at the end of the period.
 
    The $30 annual contract maintenance charge will be allocated among the
Sub-Accounts so that each Sub-Account's allocated portion of the charge is
proportionate to the percentage of the number of Contracts that have amounts
allocated to that Sub-Account.
 
NON-STANDARDIZED INVESTMENT PERFORMANCE:
 
    The Variable Account may illustrate its results over various periods and
compare its results to indices and other variable annuities in sales materials
including advertisements, brochures and reports. Such results may be computed on
a "cumulative" and/or "annualized" basis.
 
    "Cumulative" quotations are arrived at by calculating the change in the
Accumulation Unit value of a Sub-Account between the first and last day of the
base period being measured, and expressing the difference as a percentage of the
Accumulation Unit value at the beginning of the base period.
 
    "Annualized" quotations (described in the following table as "Compound
Growth Rate") are calculated by applying a formula which determines the level
rate of return which, if earned over the entire base period, would produce the
cumulative return.

    VARDS (Variable Annuity Research Data Service) provides a comprehensive
guide to variable annuity contract features and historical fund performance. The
service also provides a readily understandable analysis of the comparative
characteristics and market performance of funds included in variable contracts.

 

    STANDARD & POOR'S INDEX--Broad-based measurement of changes in stock-market
conditions based on the average performance of 500 widely held common stocks;
commonly known as the Standard & Poor's 500 (S&P 500). The selection of stocks,
their relative weightings to reflect differences in the number of outstanding
shares, and publication of the index itself are services of Standard & Poor's
Corporation, a financial advisory, securities rating, and publishing firm. The
index tracks 400 industrial company stocks, 20 transportation stocks, 40
financial company stocks, and 40 public utilities.

 

    NASDAQ-OTC Price Index--This index is based on the National Association of
Securities Dealers Automated Quotations (NASDAQ) and represents all domestic
over-the-counter stocks except those traded on exchanges and those having only
one market maker, a total of some 3,500 stocks. It is market value-weighted and
was introduced with a base of 100.00 on February 5, 1971.

 

    DOW JONES INDUSTRIAL AVERAGE (DJIA)--Price-weighted average of 30 actively

    In its advertisements and other sales literature for the Variable Account
and the Series Fund, the Company intends to illustrate the advantages of the
Contracts in a number of ways:
 
    COMPOUND INTEREST ILLUSTRATIONS. These will emphasize several advantages of
the variable annuity contract. For example, but not by way of limitation, the
literature may emphasize the potential savings through tax deferral; the
potential advantage of the Variable Account over the fixed account; and the
compounding effect when an Owner makes regular deposits to his or her Account.
 
    DOLLAR COST AVERAGING ILLUSTRATIONS. These illustrations will generally
discuss the price-leveling effect of making regular investments in the same
Sub-Accounts over a period of time, to take advantage of the trends in market
prices of the portfolio securities purchased by those Sub-Accounts.
 
    THE COMPANY'S ASSETS, SIZE. The Company may discuss its general financial
condition (see, for example, the references to Standard & Poor's, A.M. Best
Company and Duff & Phelps above). It may refer to its assets; it may also
discuss its relative size and/or ranking among companies in the industry or
among any sub-classification of those companies, based upon recognized
evaluation criteria.

                                   APPENDIX A
                               THE FIXED ACCOUNT
 
    THAT PORTION OF THE CONTRACT RELATING TO THE FIXED ACCOUNT IS NOT REGISTERED
UNDER THE SECURITIES ACT OF 1933 ("1933 ACT") AND THE FIXED ACCOUNT IS NOT
REGISTERED AS AN INVESTMENT COMPANY UNDER THE INVESTMENT COMPANY ACT OF 1940
("1940 ACT"). ACCORDINGLY, NEITHER THE FIXED ACCOUNT NOR ANY INTERESTS THEREIN
ARE SUBJECT TO THE PROVISIONS OR RESTRICTIONS OF THE 1933 ACT OR THE 1940 ACT,
AND THE DISCLOSURE IN THIS APPENDIX A HAS NOT BEEN REVIEWED BY THE STAFF OF THE
SECURITIES AND EXCHANGE COMMISSION. HOWEVER, THE FOLLOWING DISCLOSURE ABOUT THE
FIXED ACCOUNT MAY BE SUBJECT TO CERTAIN GENERALLY APPLICABLE PROVISIONS OF THE
FEDERAL SECURITIES LAWS REGARDING THE ACCURACY AND COMPLETENESS OF DISCLOSURE.
 
A WORD ABOUT THE FIXED ACCOUNT
 

    The Fixed Account is made up of all of the general assets of the Company
other than those allocated to any separate account. Purchase Payments will be
allocated to the Fixed Account as elected by the Owner at the time of purchase
or as subsequently changed. The Company will invest the assets of the Fixed
Account in those assets chosen by the Company and allowed by applicable law.
Investment income from such Fixed Account assets will be allocated between the
Company and the contracts participating in the Fixed Account, in accordance with
the terms of such contracts.

 
    Annuity payments made to Annuitants under the Contracts will not be affected
by the mortality experience (death rate) of persons receiving such payments or
of the general population. The Company assumes this "mortality risk" by virtue
of annuity rates incorporated in the Contract which cannot be changed. In
addition, the Company guarantees that it will not increase charges for
maintenance of the Contracts regardless of its actual expenses.
 
    Investment income from the Fixed Account allocated to the Company includes
compensation for mortality and expense risks borne by the Company in connection
with Fixed Account Contracts. The Company expects to derive a profit from this
compensation. The amount of such investment income allocated to the Contracts
will vary from year to year in the sole discretion of the Company. However, the
Company guarantees that it will credit interest at a rate of not less than 4%
per year, compounded annually, to amounts allocated to the Fixed Account under
the Contracts. The Company may credit interest at a rate in excess of 4% per
year; however, the Company is not obligated to credit any interest in excess of
4% per year. There is no specific formula for the determination of excess
interest credits. Such credits, if any, will be determined by the Company based
on information as to expected investment yields. Some of the factors that the
Company may consider in determining whether to credit interest to amounts
allocated to the Fixed Account and the amount thereof are general economic
trends, rates of return currently available and anticipated on the Company's
investments, regulatory and tax requirements and competitive factors. ANY
INTEREST CREDITED TO AMOUNTS ALLOCATED TO THE FIXED ACCOUNT IN EXCESS OF 4% PER
YEAR WILL BE DETERMINED IN THE SOLE DISCRETION OF THE COMPANY. THE OWNER ASSUMES
THE RISK THAT INTEREST CREDITED TO FIXED ACCOUNT ALLOCATIONS MAY NOT EXCEED THE
MINIMUM GUARANTEED OF 4% FOR ANY GIVEN YEAR.
 
    The Company is aware of no statutory limitations on the maximum amount of
interest it may credit, and the Board of Directors has set no limitations.
However, inherent in the Company's exercise of discretion in this regard is the
equitable allocation of distributable earnings and surplus among its various
policyholders and contract owners and to its sole stockholder.
 
    Excess interest, if any, will be credited on the fixed accumulation value.
The Company guarantees that, at any time, the fixed accumulation value will not
be less than the amount of Purchase Payments allocated to the Fixed Account,
plus interest at the rate of 4% per year, compounded annually, plus any
additional interest which the Company may, in its discretion, credit to the
Fixed Account, less the sum of all administrative or withdrawal charges, any
applicable premium taxes, and less any amounts surrendered. If the Owner
surrenders the Contract, the amount available from the Fixed Account will be
reduced by any applicable
 
                                       9
<PAGE>
withdrawal charge (see "Withdrawal Charges" in the Prospectus). In no event will
the portion of the contract maintenance charge that is deducted from the Fixed
Account cause the Contract's fixed accumulation value (adjusted for any cash
withdrawals) to increase by less than 4% per year.
 
    If on any Contract Anniversary the rate at which the Company credits
interest to amounts allocated to the Fixed Account under the Contract is less
than 80% of the average discount rate on 52-week United States Treasury Bills
for the most recent auction prior to the Contract Anniversary on which the
declared interest rate becomes applicable, then during the 45-day period after
the Contract Anniversary the Owner may elect to receive the value of the
Contract's Accumulation Account without assessment of a withdrawal charge. Such
withdrawal may, however, result in adverse tax consequences (see "Federal Tax
Status").
 
    The Company reserves the right to defer the payment of amounts withdrawn
from the Fixed Account for a period not to exceed six months from the date
written request for such withdrawal is received by the Company.
 
FIXED ACCUMULATION VALUE
(1) CREDITING FIXED ACCUMULATION UNITS
 
    Upon receipt of a Purchase Payment by the Company, all or that portion, if
any, of the net Purchase Payment to be allocated to the Fixed Account in
accordance with the allocation factor will be credited to the Accumulation
Account in the form of Fixed Accumulation Units. The number of Fixed
Accumulation Units to be credited is determined by dividing the dollar amount
allocated to the Fixed Account by the Fixed Accumulation Unit value for the
Contract for the Valuation Period during which the Purchase Payment is received
by the Company.
 
(2) FIXED ACCUMULATION UNIT VALUE
 
    A Fixed Accumulation Unit value is established at $10.00 for the first
Valuation Period of the calendar month in which the Contract is issued and will
increase for each successive Valuation Period as interest is accrued. All
Contracts issued in a particular calendar month and at a particular rate of
interest, as specified in advance by the Company from time to time, will use the
same series of Fixed Accumulation Unit values throughout the first Contract
Year.
 
    At the first Contract Anniversary the Fixed Accumulation Units credited to a
Contract's Accumulation Account will be exchanged for a second type of Fixed
Accumulation Unit with an equal aggregate value. The value of this second type
of Fixed Accumulation Unit will increase for each Valuation Period during each
Contract Year as interest is accrued at a rate which shall have been determined
by the Company prior to the first day of each Contract Year.
 
    The Company will credit interest to the Contract's Fixed Accumulation
Account at a rate of not less than 4% per year, compounded annually. Once the
rate applicable to a specific Contract is established by the Company, it may not
be changed for the balance of the Contract Year. Additional Payments made during
the Contract Year will be credited with interest for the balance of the Contract
Year at the rate applicable at the beginning of that Contract Year. The Fixed
Accumulation Unit value for the Contract for any Valuation Period is the value
determined as of the end of such Valuation Period.
 
(3) FIXED ACCUMULATION VALUE
 
    The fixed accumulation value of a Contract, if any, for any Valuation Period
is equal to the value of the Fixed Accumulation Units credited to the
Accumulation Account for such Valuation Period.
 
LOANS FROM THE FIXED ACCOUNT (QUALIFIED CONTRACTS ONLY)
 
    Loans will be permitted from the Contract's Fixed Accumulation Account (to
the extent permitted by the retirement plan for which the Contract is purchased)
UNDER QUALIFIED CONTRACTS ONLY. The maximum loan amount is the amount determined
under the Company's maximum loan formula for qualified plans. The minimum loan
amount is $1,000. Loans will be secured by a security interest in the Contract.
Loans are
 
                                       10
<PAGE>
subject to applicable retirement program legislation and their taxation is
determined under the federal income tax laws. The amount borrowed will be
transferred to a fixed minimum guarantee accumulation account in the Company's
general account where it will accrue interest at a specified rate below the then
current loan interest rate. Generally, loans must be repaid within five years.
 
    The amount of the death benefit, the amount payable on a full surrender and
the amount applied to provide an annuity on the Annuity Commencement Date will
be reduced to reflect any outstanding loan balance (plus accrued interest
thereon). Partial withdrawals may be restricted by the maximum loan limitation.
 
FIXED ANNUITY PAYMENTS
 
    The dollar amount of each fixed annuity payment will be determined in
accordance with the annuity payment rates found in the Contract which are based
on a minimum guaranteed interest rate of 4% per year, or, if more favorable to
the Payee(s), in accordance with the Single Premium Immediate Settlement Rates
published by the Company and in use on the Annuity Commencement Date.
 
                                   APPENDIX B
 
ILLUSTRATIVE EXAMPLE OF VARIABLE ACCUMULATION UNIT VALUE CALCULATIONS
 
    Suppose the net asset value of a particular Series Fund share at the end of
the current Valuation Period is $18.38; at the end of the immediately preceding
Valuation Period is $18.32; the Valuation Period is one day; no dividends or
distributions caused the particular Series Fund shares to go "ex-dividend"
during the current Valuation Period. $18.38 divided by $18.32 is 1.00327511.
Subtracting the one day risk factor for mortality and expense risks of .00003539
(the daily equivalent of the current charge of 1.3% on an annual basis) gives a
net investment factor of 1.00323972. If the value of the Variable Accumulation
Unit for the immediately preceding Valuation Period had been 14.5645672, the
value for the current Valuation Period would be 14.6117523 (14.5645672 X
1.00323972).
 
ILLUSTRATIVE EXAMPLE OF VARIABLE ANNUITY UNIT VALUE CALCULATIONS
 
    Suppose the circumstances of the first example exist, and the value of an
Annuity Unit for the immediately preceding Valuation Period had been 12.3456789.
If the first variable annuity payment is determined by using an annuity payment
based on an assumed interest rate of 4% per year, the value of the Annuity Unit
for the current Valuation Period would be 12.3843446 (12.3456789 X 1.0032372 X
0.99989255).
 
ILLUSTRATIVE EXAMPLE OF VARIABLE ANNUITY PAYMENT CALCULATIONS
 
    Suppose that the Accumulation Account of a deferred Contract is credited
with 8,765.4321 Variable Accumulation Units of a particular Sub-Account but is
not credited with any Fixed Accumulation Units; that the Variable Accumulation
Unit value and the Annuity Unit value for the particular Sub-Account for the
Valuation Period which ends immediately preceding the Annuity Commencement Date
are 14.5645672 and 12.3456789, respectively; that the annuity payment rate for
the age and option elected is $6.78 per $1,000; and that the Annuity Unit value
on the day prior to the second variable annuity payment date is 12.3843446. The
first variable annuity payment would be $865.57 (8,765.4321 X 14.5645672 X 6.78
divided by 1,000). The number of Annuity Units credited would be 70.1112
($865.57 divided by 12.3456789) and the second variable annuity payment would be
$868.28 (70.1112 X 12.3843446).
 
                                       11
<PAGE>
                                   APPENDIX C
                       WITHDRAWALS AND WITHDRAWAL CHARGES
 
    Suppose, for example, that the initial Purchase Payment under a Contract was
$2,000, and that $2,000 Purchase Payments were made on each Contract Anniversary
thereafter. The maximum free withdrawal amount would be $200, $400, $600, $800,
and $1,000 in Contract Years 1, 2, 3, 4, and 5, respectively; these amounts are
determined as 10% of the new Payments (as new Payments are defined in each
Contract Year).
 
    In Contract Years after the 5th, the maximum free withdrawal amount will 
be increased by any old Payments which have not already been liquidated. 
Continuing the example, consider a partial withdrawal of $4,500 made during 
the 7th Contract Year. Let us consider this withdrawal under two sets of 
circumstances: first where there were no previous partial withdrawals, and 
second where there had been an $800 cash withdrawal payment made in the 5th 
Contract Year.
 
    1.  In the first instance, there were no previous partial withdrawals. The
       maximum free withdrawal amount in the 7th Contract Year is then $5,000,
       which consists of $4,000 in old Payments ($2,000 from each of the first
       two Contract Years) and $1,000 as 10% of the new Payments in years 3-7.
       Because the $4,500 partial withdrawal is less than the maximum free
       withdrawal amount of $5,000, no withdrawal charge would be imposed.
 
        This withdrawal would liquidate the Purchase Payments which were made in
       Contract Years 1 and 2, and would liquidate $500 of the Purchase Payment
       which was made in Contract Year 3.
 
    2.  In the second instance, an $800 cash withdrawal payment had been made in
       the 5th Contract Year. Because the cash withdrawal payment was less than
       the $1,000 maximum free withdrawal amount in the 5th Contract Year, no
       surrender charge would have been imposed. The $800 cash withdrawal
       payment would have liquidated $800 of the Purchase Payment in the 1st
       Contract Year.
 
       As a consequence, the maximum free withdrawal amount in the 7th 
       Contract Year is only $4,200, consisting of $3,200 in old Payments 
       ($1,200 remaining from Contract Year 1 and $2,000 from Contract Year 
       2) and $1,000 as 10% of new Payments. A $4,500 partial withdrawal 
       exceeds the maximum free withdrawal amount by $300. Therefore the 
       amount subject to the withdrawal charge is $300 and the withdrawal 
       charge is $300 X 0.05, or $15. The amount of the cash withdrawal 
       payment is the $4,500 partial withdrawal, minus the $15 withdrawal 
       charge, or $4,485. The $4,500 partial withdrawal would be charged to 
       the Contract's Accumulation Account in the form of cancelled 
       Accumulation Units.
 
        This withdrawal would liquidate the remaining $1,200 from the Purchase
       Payment in Contract Year 1, the full $2,000 Purchase Payment from
       Contract Year 2, and $1,300 of the Payment from Contract Year 3.
 
    Suppose that the Owner of the Contract wanted to make a full surrender of 
the Contract in Contract Year 7 instead of a $4,500 partial withdrawal. The 
consequences would be as follows:
 
    1.  In the first instance, where there were no previous cash withdrawal
       payments, we know from above that the maximum free withdrawal amount in
       the 7th Contract Year is $5,000. The sum of the old and new Payments not
       previously liquidated is $14,000 ($2,000 from each Contract Year). The
       amount subject to the withdrawal charge is thus $9,000. The withdrawal
       charge on full surrender would then be $9,000 X 0.05 or $450.
 
    2.  In the second instance, where $800 had previously been withdrawn, we
       know from above that the maximum free withdrawal amount in the 7th
       Contract Year is $4,200. The sum of old and new Payments not previously
       liquidated is $14,000 less the $800 which was previously liquidated, or
       $13,200. The amount subject to the withdrawal charge is still $9,000
       ($13,200 - $4,200). The withdrawal charge on full surrender would thus be
       the same as in the first example.

          Omitted from the list are subsidiaries of Sun Life Assurance Company
of Canada which, considered in the aggregate, would not constitute a
"significant subsidiary" (as that term is defined in Rule 8b-2 under Section 8
of the Investment Company Act of 1940) of Sun Life Assurance Company of Canada.

          None of the companies listed is a subsidiary of the Registrant,
therefore the only financial statements being filed are those of Sun Life
Insurance and Annuity Company of New York.

Item 27.       NUMBER OF CONTRACT OWNERS
   
          As of January 31, 1999 there were 1,692 qualified and 1,675 
non-qualified contracts.
    
Item 28.       INDEMNIFICATION

          Article 5, Section 5.6 of the By-laws of Sun Life Insurance and
Annuity Company of New York, a copy of which was filed as Exhibit A.(6)(b) to
the Registration Statement of the Registrant on Form N-8B-2 (File No. 811-4183),
provides for indemnification of  directors, officers and employees of Sun Life
Insurance and Annuity Company of New York.

          Insofar as indemnification for liability arising under the Securities
Act of 1933 may be permitted to directors, officers and controlling persons of
Sun Life Insurance and Annuity Company of New York pursuant to the certificate
of incorporation, by-laws, or otherwise, Sun Life (N.Y.) has been advised that
in the opinion of the Securities and Exchange Commission such indemnification is
against public policy as expressed in the Act and is, therefore, unenforceable.
In the event that a claim for indemnification against such liabilities (other
than the payment by Sun Life (N.Y.) of expenses incurred or paid by a director,
officer, or controlling person of Sun Life (N.Y.) 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, Sun Life
(N.Y.) will, unless  in the opinion of their counsel the matter has been settled
by controlling precedent, submit to a court of appropriate jurisdiction the
question  whether such indemnification by  them is against public policy as
expressed in the Act and will be governed by the final adjudication of such
issue.
