                                    ANNUITY

      THIS PROFILE IS A SUMMARY OF SOME OF THE MORE IMPORTANT POINTS THAT YOU
SHOULD KNOW AND CONSIDER BEFORE PURCHASING THE CONTRACT. THE CONTRACT IS MORE
FULLY DESCRIBED IN THE FULL PROSPECTUS WHICH ACCOMPANIES THIS PROFILE. PLEASE
READ THE PROSPECTUS CAREFULLY.

      1. THE FUTURITY ANNUITY

      The Futurity Annuity is a flexible payment deferred annuity contract
("Contract") designed for use in connection with retirement and deferred
compensation plans, some of which may qualify for favorable federal income tax
treatment. The Contract is intended to help you achieve your retirement savings
or other long-term investment goals.

      The Contract has two phases: an Accumulation Phase and an Income Phase.
During the Accumulation Phase you make payments into the Contract; any
investment earnings under your Contract accumulate on a tax-deferred basis and
are taxed as income only when withdrawn. During the Income Phase, we make
annuity payments in amounts determined in part by the amount of money you have
accumulated under your Contract during the Accumulation Phase. You choose when
the Income Phase begins.

      You may choose among 33 variable investment options and a range of fixed
interest options. For a variable investment return you choose one or more
Sub-Accounts in our Variable Account, each of which invests in shares of a
corresponding mutual fund or series thereof (collectively, the "Funds") listed
in Section 4. The value of any portion of your Contract allocated to the
Sub-Accounts will fluctuate up or down depending on the performance of the Funds
you select, and you may experience losses. For a fixed interest rate, you may
choose one or more Guarantee Periods offered in our Fixed Account, each of which
earns its own Guaranteed Interest Rate if you keep your money in that Guarantee
Period for the specified length of time.


      The Contract is designed to meet your need for investment flexibility.
Over the life of your Contract, you may allocate amounts among as many as 18 of
the available variable and fixed options. Until we begin making annuity payments
under your Contract, you can, subject to certain limitations, transfer money
between options up to 12 times each year without a transfer charge or adverse
tax consequences.


      2. ANNUITY PAYMENTS (THE INCOME PHASE)

      Just as you can elect to have your Contract value accumulate on either a
variable or fixed basis, or a combination of both, you can elect to receive
annuity payments on either a variable or fixed basis or both. If you choose to
have any part of your annuity payments come from the Sub-Accounts, the dollar
amount of your annuity payments may fluctuate.

      The Contract offers a variety of annuity options. You can select from
among the following methods of receiving either variable or fixed annuity
payments under your Contract: (1) monthly payments continuing for your lifetime
(assuming you are the annuitant); (2) monthly payments for your lifetime, but
with payments continuing to your chosen beneficiary for 5, 10, 15 or 20 years if
you die before the end of the period you have selected; (3) monthly payments for
your lifetime and the life of another person (usually your spouse) you have
chosen; and (4) monthly payments for a specified number of years (between 5 and
30), with a cash-out option for variable payments. You can also select a fixed
payment option, where we will hold the amount applied to provide fixed annuity
payments, with interest accrued at the rate we determine from time to time,
which will be at least 3% per year. We may also agree to other annuity options
at our discretion.

      Once the Income Phase begins, you cannot change your choice of annuity
payment method.
<PAGE>
      3. PURCHASING A CONTRACT

      You may purchase a Contract for $5,000 or more, under most circumstances.
You may increase the value of your investment by adding $1,000 or more at any
time during the Accumulation Phase. We may waive these limits. We will not
accept a purchase payment if your account value is over $1 million, or if the
purchase payment would cause your account value to exceed $1 million, unless we
have approved the payment in advance.

      4. ALLOCATION OPTIONS


      You can allocate your money among Sub-Accounts investing in the following

      Market conditions will determine the value of an investment in any Fund.
Each Fund is described in the relevant Fund prospectus.

      In addition to these variable options, you may also allocate your money to
one or more of the Guarantee Periods we make available. For each Guarantee
Period, we offer a Guaranteed Interest Rate for the specified length of time.

      5. EXPENSES

      The charges under the Contracts are as follows:

      During the first 5 years of a Contract, we impose an annual Account Fee
equal to the lesser of $30 or 2% of the value of your Contract. After the fifth
year, we may change this fee annually, but it will never exceed the lesser of
$50 or 2% of the value of your Contract. During the Income Phase, the annual
Account Fee is $30. We also deduct insurance charges (which include an
administrative expense charge) equal to 1.40% per year of the average daily
value of the Contract allocated among the Sub-Accounts.

                                       2
<PAGE>
      There are no sales charges when you purchase your Contract. However, if
you withdraw money from your Contract, we will, with certain exceptions, impose
a withdrawal charge. Your Contract allows a "free withdrawal amount," which you
may withdraw before you incur the withdrawal charge. The rest of your withdrawal
is subject to a withdrawal charge equal to a percentage of each purchase payment
you withdraw. Each payment begins a new seven-year period and moves down a
declining surrender charge scale at each Contract Anniversary. Payments received
during the current Contract Year will be charged 6% if withdrawn. On your next
scheduled Contract Anniversary, that payment, along with any other payments made
during that Contract Year, will be considered to be in their second Contract
Year and will have a 5% withdrawal charge. On the next Contract Anniversary,
these payments will move into their third Contract Year and will have a
withdrawal charge of 5%, if withdrawn. The withdrawal charge decreases according
to the number of Contract Years the purchase payment has been in your Account.
The declining scale is as follows:


<TABLE>
<CAPTION>
   NUMBER OF
 YEARS PURCHASE
  PAYMENT HAS
  BEEN IN YOUR
    ACCOUNT        WITHDRAWAL CHARGE
- ----------------   -----------------
<S>                <C>
  0-1                      6%
  2-3                      5%
  4-5                      4%
  6                        3%
  7 or more                0%
</TABLE>



      If you withdraw, transfer, or annuitize money allocated to a Guarantee
Period more than 30 days before the expiration date of the Guarantee Period, the
amount will be subject to a Market Value Adjustment. This adjustment reflects
the relationship between our current Guaranteed Interest Rates and the
Guaranteed Interest Rate applicable to the amount being withdrawn. Generally, if
your Guaranteed Interest Rate is lower than the relevant current rate, then the
adjustment will decrease your Contract value. Conversely, if your Guaranteed
Interest Rate is higher than the relevant current rate, the adjustment will
increase your Contract value. The Market Value Adjustment will not apply to the
withdrawal of interest credited during the current year, or to transfers as part
of our dollar-cost averaging program.



      In addition to the charges we impose under the Contracts, there are
charges (which include management fees and operating expenses) imposed by each
Fund, which range from 0.57% to 1.40% of the average net assets of the Fund,
depending upon which Fund you have selected. The investment advisers to some of
the Funds have agreed to waive or reimburse a portion of Fund expenses; without
this agreement, Fund expenses could be higher. Some of these arrangements may be
terminated at any time.


      The following chart is designed to help you understand the expenses you
will incur under your Contract, if you invest in one or more of the
Sub-Accounts. The column "Total Annual Expenses" shows the sum of the "Total
Annual Insurance Charges," as defined just above the chart, and the total
expenses (net of any applicable expense reimbursement and/or fee waivers) for
each Fund. The next two columns show two examples of the expenses, in dollars,
you would pay under a Contract. The examples assume that you invested $1,000 in
a Contract which earns 5% annually and that you withdraw your money (1) at the
end of one year or (2) at the end of 10 years. For the first year, the Total
Annual Expenses are deducted, as well as withdrawal charges. For year 10, the
example shows the aggregate of all of the annual expenses deducted for the 10
years, but there is no withdrawal charge.

      "Total Annual Insurance Charges" of 1.50% as shown in the table below
include the insurance charges of 1.40% of your Account's daily net assets (1.25%
for mortality and expense risks and 0.15% for administrative expenses), plus an
additional 0.10%, which is used to represent the $30 annual

                                       3
<PAGE>
Account Fee based on an assumed Contract value of $30,000. The actual impact of
the Account Fee may be greater or less than 0.10%, depending upon the value of
your Contract.

      For more detailed information about Contract fees and expenses, please
refer to the fee table and discussion of Contract charges contained in the full
Prospectus which accompanies this Profile.

      6. TAXES

      Under current federal tax laws, your earnings are not taxed until you take
them out of your Contract. If you take money out, earnings come out first and
are taxed as income. If your Contract is funded with pre-tax or tax-deductible
dollars (such as with a pension or IRA contribution -- we call this a Qualified
Contract -- your entire withdrawal will be taxable. If you are younger than
59 1/2 when you take money out, you may be charged a 10% federal penalty tax on
the earnings. Annuity payments during the Income Phase are considered in part a
return of your original investment. That portion of each payment is not taxable,
except under a Qualified Contract, in which case the entire payment will be
taxable. In all cases, you should consult with your tax adviser for specific tax
information.


      Under the tax laws of Puerto Rico, when an annuity payment is made under
your Contract, your Annuitant or any other Payee is required to include as gross
income the portion of each annuity payment equal to 3% of the aggregate purchase
payments you made under the Contract. The amount, if any, in excess of the
included amount is excluded from gross income. After an amount equal to the
aggregate amount excluded from gross income has been received, all of the
annuity payments are considered to be taxable income. You should consult with
your tax adviser for specific tax information.


                                       4
<PAGE>
      7. ACCESS TO YOUR MONEY

      You can withdraw or transfer money from your Contract at any time during
the Accumulation Phase. You may withdraw a portion of the value of your Contract
in each year without the imposition of the withdrawal charge -- 10% of all
payments you have made in the last 7 years, plus any payment we have held for at
least 7 years. All other purchase payments you withdraw will be subject to a
withdrawal charge ranging from 6% to 0%. You may also be required to pay income
tax and possible tax penalties on any money you withdraw.

      We do not assess a withdrawal charge upon annuitization or transfers. In
certain circumstances, we will waive the withdrawal charges for a full
withdrawal when you are confined to an eligible nursing home. In addition, there
may be other circumstances under which we may waive the withdrawal charge.

      In addition to the withdrawal charge, amounts you withdraw, transfer or
annuitize from the Fixed Account before your Guarantee Period has ended may be
subject to a Market Value Adjustment.

      8. PERFORMANCE

      If you invest in the Variable Account, the value of your Contract will
increase or decrease depending upon the investment performance of the Fund you
choose.

      The following chart shows total returns for investment in the variable
options where the corresponding Series has at least one full calendar year of
operations. The returns reflect all charges and deductions of the Series and
Sub-Accounts and deduction of the Annual Account Fee. They do not reflect
deduction of any withdrawal charges or premium taxes. These charges, if
included, would reduce the performance numbers shown. Past performance is not a
guarantee of future results.

      9. DEATH BENEFIT

      If the annuitant dies before the Contract reaches the Income Phase, the
beneficiary will receive a death benefit. To calculate the death benefit, we use
a "Death Benefit Date," which is the earliest date we have both due proof of
death and a written request specifying the manner of payment.

      If the annuitant was 85 or younger when we issued your Contract, the death
benefit is the greatest of:

      (1) The value of the Contract on the Death Benefit Date;

      (2) The amount we would pay in the event of a full surrender of the
          Contract on the Death Benefit Date;


      (3) The value of the Contract on the most recent seven-year anniversary of
          the Contract, plus any purchase payments made and adjusted for any
          partial withdrawals and charges made after that anniversary; and


      (4) Your total purchase payments minus the sum of partial withdrawals;
          interest will accrue daily on each purchase payment and each partial
          withdrawal at a rate equivalent to 5% per year until the first day of
          the month following the annuitant's 80th birthday, or until the
          purchase payment or partial withdrawal has doubled in amount,
          whichever is earlier.

      If the annuitant was 86 or older when we issued your Contract, the death
benefit is equal to the amount set forth in (2) above, in this Section 9.

      10. OTHER INFORMATION

      FREE LOOK. Depending upon applicable state law, if you cancel your
Contract within 10 days after receiving it we will send you the value of your
Contract as of the day we received your cancellation request (this may be more
or less than the original purchase payment) and we will not deduct a withdrawal
charge. However, if applicable state or federal law requires, we will refund the
full amount of any purchase payment(s) we receive and the "free look" period may
be greater than 10 days.

      NO PROBATE. In most cases, when you die, the beneficiary will receive the
death benefit without going through probate. However, avoiding probate does not
mean that the beneficiary will not have tax liability as a result of receiving
the death benefit.


      WHO SHOULD PURCHASE A CONTRACT? The Contract is designed for those seeking
long-term tax-deferred accumulation of assets and annuity features, generally
for retirement or other long-term investment purposes. The tax-deferred feature
is most attractive to purchasers in high federal and state income tax brackets.
You should note that qualified retirement investments automatically provide tax
deferral regardless of whether the underlying contract is an annuity. You should
not buy a Contract if you are looking for a short-term investment or if you do
not wish to cannot risk a decrease in the value of your investment.


      CONFIRMATIONS AND QUARTERLY STATEMENTS. You will receive a confirmation of
each transaction within your Contract, except for those transactions which are
part of an automatic program, such as Dollar-Cost Averaging, Asset Allocation,
Systematic Withdrawal and/or Portfolio Rebalancing. On a quarterly basis, you
will receive a complete statement of your transactions over the past quarter and
a summary of your Account values at the end of that period.

      ADDITIONAL FEATURES. The Contract offers the following additional
convenient features, which you may choose at no extra charge.

      DOLLAR-COST AVERAGING -- This program lets you invest gradually in up to
12 Sub-Accounts.

      ASSET ALLOCATION -- One or more asset allocation programs may be available
in connection with the Contract.

      SYSTEMATIC WITHDRAWAL PROGRAM -- This program allows you to receive
quarterly, semi-annual or annual payments during the Accumulation Phase.

                                       6
<PAGE>
      PORTFOLIO REBALANCING PROGRAM -- Under this program, we automatically
reallocate your investments in the Sub-Accounts to maintain the proportions you
select. You can elect rebalancing on a quarterly, semi-annual or annual basis.

                                 SPECIAL TERMS

      Your Contract is a legal document that uses a number of specially defined
terms. We explain most of the terms that we use in this Prospectus in the
context where they arise, and some are self-explanatory. In addition, for
convenient reference, we have compiled a list of these terms in the Glossary
included at the back of this Prospectus as Appendix A. If, while you are reading
this Prospectus, you come across a term that you do not understand, please refer
to the Glossary for an explanation.

                                EXPENSE SUMMARY

      The purpose of the following table is to help you understand the costs and
expenses that you will bear directly and indirectly under a Contract WHEN YOU
ALLOCATE MONEY TO THE VARIABLE ACCOUNT. The table reflects expenses of the
Variable Account as well as of each Fund. The table should be considered
together with the narrative provided under the heading "Contract Charges" in
this Prospectus, and with the Funds' prospectuses. In addition to the expenses
listed below, we may deduct premium taxes.

- ------------------------------
(1) The information relating to Fund expenses was provided by the Funds and we
    have not independently verified it. You should consult the Fund prospectuses
    for more information about Fund expenses.

(2) For all Funds, "Management Fees," "Other Expenses" and "Total Fund Annual
    Expenses" are based on actual expenses for the fiscal year ended December
    31, 1999, net of any applicable expense reimbursement or waiver.

(3) The investment advisers for the Goldman Sachs VIT Funds have voluntarily
    agreed to waive or reimburse a portion of the management fees and/or
    operating expenses, resulting in a reduction of the total expenses. In
    particular, the investment advisers to the Goldman Sachs VIT CORE-SM- Large
    Capital Growth Fund, the Goldman Sachs VIT CORE-SM- Small Cap Equity Fund,
    the Goldman Sachs VIT CORE-SM- U.S. Equity Fund, the Goldman Sachs VIT
    Growth and Income Fund and the Goldman Sachs VIT International Equity Fund
    have voluntarily agreed to reduce or limit certain "Other Expenses" of such
    Funds (excluding management fees, taxes, interest and brokerage fees,
    litigation, indemnification and other extraordinary expenses) to the extent
    such expenses exceed 0.20%, 0.25%, 0.20%, 0.25%, and 0.35% per annum of such
    Funds' average daily net assets, respectively. The expenses of the Goldman
    Sachs VIT Funds are estimated for the fiscal year ended December 31, 2000.
    Absent any such waiver or reimbursement, estimated "Management Fees,"
    estimated "Other Expenses," and estimated "Total Fund Annual Expenses" for
    the year ended December 31, 2000 will be: 0.70%, 0.42%, and 1.12% for the
    Goldman Sachs VIT Core-SM- Large Cap Growth Fund; 0.75%, 0.75%, and 1.50%
    for the Goldman Sachs VIT CORE-SM- Small Cap Equity Fund; 0.70%, 0.20%, and
    0.90% for the Goldman Sachs VIT CORE-SM- U.S. Equity Fund; 0.75%, 0.47%, and
    1.22% for the Goldman Sachs VIT Growth and Income Fund; and 1.00%, 0.77%,
    and 1.77% for the Goldman Sachs VIT International Equity Fund. Fee waivers
    and expense reimbursements for the Goldman Sachs Funds may be discontinued
    at any time.


(4) An affiliate of the adviser has agreed to reimburse the Fund, to the extent
    certain expenses exceed the following percentages of the Fund's average
    daily net assets through fiscal year 2000: 0.85% for the J.P. Morgan U.S.
    Disciplined Equity Portfolio; 1.20% for the J.P. Morgan International
    Opportunities Portfolio, and 1.15% for the J.P. Morgan Small Company
    Portfolio. Absent this reimbursement, "Total Fund Annual Expenses" would
    have been 0.87% for the J.P. Morgan U.S. Disciplined Equity Portfolio, 1.98%
    for the J.P. Morgan International Opportunities Portfolio, and 2.57% for the
    J.P. Morgan Small Company Portfolio.



(5) The Fund has an expense offset arrangement which reduces the Fund's
    custodian fee based upon the amount of cash maintained by the Fund with its
    custodian and dividend disbursing agent, and may enter into such other
    arrangements and directed brokerage arrangement (which would also have the
    effect of reducing the Fund's expenses). Any such fee reductions are not
    reflected in the table. Had these fees been taken into account, "Total Fund
    Expenses" would have been: 0.75% for the MFS/Sun Life Capital Appreciation
    Series; and 0.81% for the MFS/Sun Life Utilities Series.


                                       5
<PAGE>

(6) Total Fund Annual Expenses for the OCC Equity Portfolio, the OCC Small Cap
    Portfolio, and the OCC Mid Cap Portfolio are limited contractually by OpCap
    Advisers so that the Funds' respective annualized operating expenses (net of
    expense offsets) do not exceed 1% of average daily net assets. Absent this
    limit, "Management Fees", "Other Expenses" and "Total Expenses" were 0.80%,
    0.93%, and 1.73% for the OCC Mid Cap Portfolio. "Other Expenses" are shown
    gross of expense offsets afforded the portfolio, which effectively lowered
    custody expenses.



(7) The Fund's investment adviser has voluntarily agreed to waive a portion of
    its management fee and/or to reimburse the Fund for expenses, resulting in a
    reduction of total Fund expenses. Absent and such waiver or reimbursement,
    "Total Fund Annual Expenses" were: 1.65% for the Salomon Brothers Variable
    Capital Fund; 1.15% for the Salomon Brothers Variable Investors Fund; 1.48%
    for the Salomon Brothers Variable Strategic Bond Fund; and 1.65% for the
    Salomon Brothers Variable Total Return Fund.



(8) The investment adviser for the indicated Funds has voluntarily agreed to
    waive or reimburse a portion of the management fees and/or operating
    expenses, resulting in a reduction of the total expenses. Absent any such
    waiver or reimbursement, "Management Fees," "Other Expenses," and "Total
    Fund Annual Expenses" were: 1.25%, 1.88%, and 3.13% for the Warburg Pincus
    Emerging Markets Portfolio; and 1.25%, 0.33%, and 1.58% for the Warburg
    Pincus Global Post-Venture Capital Portfolio. Fee waivers and expense
    reimbursements for the indicated Funds may be discontinued at any time.

                        CONDENSED FINANCIAL INFORMATION

      Historical information about the value of the units we use to measure the
variable portion of your Contract ("Variable Accumulation Units") is included in
the back of this Prospectus as Appendix B.

                              THE ANNUITY CONTRACT

      Sun Life Assurance Company of Canada (U.S.) (the "Company", "we" or "us")
and Sun Life of Canada (U.S.) Variable Account F (the "Variable Account") offer
the Contract to groups and individuals for use in connection with their
retirement plans. The Contracts are available on a group basis and, in certain
states, may be available on an individual basis. We issue an Individual Contract
directly to the individual owner of the Contract. We issue a Group Contract to
the Owner covering all individuals participating under the Group Contract. Each
individual receives a Certificate that evidences his or her participation under
the Group Contract.

      In this Prospectus, unless we state otherwise, we refer to both the owners
of Individual Contracts and participating individuals under Group Contracts as
"Participants" and we address all those Participants as "you"; we use the term
"Contracts" to include Individual Contracts, Group Contracts and Certificates
issued under Group Contracts. For the purpose of determining benefits under both
Individual Contracts and Group Contracts, we establish an Account for each
Participant, which we will refer to as "your" Account or a "Participant
Account."

      Your Contract provides a number of important benefits for your retirement
planning. It has an Accumulation Phase, during which you make payments under the
Contract and allocate them to one or more Variable Account or Fixed Account
options, and an Income Phase, during which we make payments based on the amount
you have accumulated. Your Contract provides tax deferral, so that you do not
pay taxes on your earnings under your Contract until you withdraw them. It
provides a death benefit if the Annuitant dies during the Accumulation Phase.
Finally, if you so elect, during the Income Phase we will make payments to you
or someone else for life or for another period that you choose.

      You choose these benefits on a variable or fixed basis or a combination of
both. When you choose Variable Account investment options or a Variable Annuity
option, your benefits will be responsive to changes in the economic environment,
including inflationary forces and changes in rates of return available from
different types of investments. With these options, you assume all investment
risk under the Contract. When you choose a Guarantee Period in our Fixed Account
or a Fixed Annuity option, we assume the investment risk, except in the case of
early withdrawals, where you bear the risk of unfavorable interest rate changes.
You also bear the risk that the interest rates we will offer in the future and
the rates we will use in determining your Fixed Annuity may not exceed our
minimum guaranteed rate, which is 3% per year, compounded annually.

      The Contracts is designed for use in connection with retirement and
deferred compensation plans, some of which qualify for favorable federal income
tax treatment under Sections 401, 403, 408 or 408A of the Internal Revenue Code.
The Contracts is also designed so that it may be used in connection with certain
non-tax-qualified retirement plans, such as payroll savings plans and such other
groups (trusteed or nontrusteed) as may be eligible under applicable law. We
refer to Contracts used with plans that receive favorable tax treatment as
"Qualified Contracts," and all others as "Non-Qualified Contracts."

                    COMMUNICATING TO US ABOUT YOUR CONTRACT

      All materials sent to us, including Purchase Payments, must be sent to us
at our Annuity Mailing Address as set forth on the first page of this

actually receive them at our Annuity Mailing Address. However, we will consider
Purchase Payments, withdrawal requests and transfer instructions to

                                       9

                  SUN LIFE ASSURANCE COMPANY OF CANADA (U.S.)

      We are a stock life insurance company incorporated under the laws of
Delaware on January 12, 1970. We do business in 48 states, the District of
Columbia, and Puerto Rico, and we have an insurance company subsidiary that does
business in New York. Our Executive Office mailing address is One Sun Life
Executive Park, Wellesley Hills, Massachusetts 02481.

      We are an indirect wholly-owned subsidiary of Sun Life Assurance Company
of Canada ("Sun Life (Canada)"). Sun Life (Canada) completed its demutualization
on March 22, 2000. As a result of the demutualization, a new holding company,
Sun Life Financial Services of Canada Inc. ("Sun Life Financial"), is now the
ultimate parent of Sun Life (Canada) and the Company. Sun Life Financial, a
corporation organized in Canada, is a reporting company under the Securities
Exchange Act of 1934 with common shares listed on the Toronto, New York, London,
and Manila stock exchanges.

                              THE VARIABLE ACCOUNT


      We established the Variable Account as a separate account on July 13,
1989, pursuant to a resolution of our Board of Directors. The Variable Account
funds the Contract and various other variable annuity and variable life
insurance product contracts which are offered by the Company and other
affiliated and unaffiliated offerors. These other products may have features,
benefits and charges that are different from those under the Contract.


      Under Delaware insurance law and the Contract, 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. These assets are held in relation to the Contracts described in this
Prospectus and other variable annuity contracts that provide benefits that vary
in accordance with the investment performance of the Variable Account. Although
the assets maintained in the Variable Account will not be charged with any
liabilities arising out of any other business we conduct, 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 Fund. All amounts
allocated to the Variable Account will be used to purchase Fund shares as
designated by you at their net asset value. Any and all distributions made by
the Fund with respect to the shares held by the Variable Account will be
reinvested to purchase additional shares at their net asset value. Deductions
from the Variable Account for cash withdrawals, annuity payments, death
benefits, Account Fees, contract charges against the assets of the Variable
Account for the assumption of mortality and expense risks, administrative
expenses and any applicable taxes will, in effect, be made by redeeming the
number of 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 Fund
shares at all times.

                           VARIABLE ACCOUNT OPTIONS:
                                   THE FUNDS

below. Each Fund is a mutual fund registered under the Investment Company Act of
1940, or a separate series of shares of such a mutual fund.

     the right to invest predominantly in medium or lower rated securities.

     SALOMON BROTHERS VARIABLE TOTAL RETURN FUND seeks above average income

     secondarily, growth of capital and income, through investments in a broad
     variety of equity and fixed income securities and short-term obligations.

     EMERGING MARKETS PORTFOLIO seeks long-term growth of capital by investing
     primarily in equity securities of non-United States issuers consisting of
     companies in emerging securities markets.

     GLOBAL POST-VENTURE CAPITAL PORTFOLIO (formerly, the Post-Venture Capital
     Portfolio) seeks long-term growth of capital by investing primarily in
     equity securities of issuers in their post-venture capital stage of
     development and pursues an aggressive investment strategy.

     INTERNATIONAL EQUITY PORTFOLIO seeks long-term capital appreciation by
     investing in equity securities of non-U.S. issuers.

     SMALL COMPANY GROWTH PORTFOLIO seeks capital growth by investing in equity
     securities of small-sized domestic companies.

      The Funds may also be available to registered separate accounts offering
variable annuity and variable life products of other affiliated and unaffiliated
insurance companies, as well as to the Variable Account and other separate
accounts of the Company. Although we do not anticipate any disadvantages to
this, there is a possibility that a material conflict may arise between the
interests of the Variable Account and one or more of the other separate accounts
participating in the Funds. A conflict may occur due to a change in law
affecting the operations of variable life and variable annuity separate
accounts, differences in the voting instructions of the Participants and Payees
and those of other companies, or some other reason. In the event of conflict, we
will take any steps necessary to protect Participants and Payees, including
withdrawal of the Variable Account from participation in the underlying Funds
which are involved in the conflict or substitution of shares of other Funds.


      Certain of the investment advisers to the Funds may reimburse us for
administrative costs in connection with administering the Funds as options under
the Contracts. These amounts are not charged to the Funds or Participants, but
are paid from assets of the advisers, except for the administrative costs of the
Lord Abbett Growth & Income Portfolio, which are paid from Fund assets.



      Certain publicly available mutual funds may have similar investment goals
and principal investment policies and risks as one or more of the Funds, and may
be managed by a Fund's portfolio manager(s). While a Fund may have many
similarities to these other funds, its investment performance will differ from
their investment performance. This is due to a number of differences between a
Fund and these similar products, including differences in sales charges, expense
ratios and cash flows.

                               THE FIXED ACCOUNT

      The Fixed Account is made up of all the general assets of the Company
other than those allocated to any separate account. Amounts you allocate to
Guarantee Periods become part of the Fixed Account, and are available to fund
the claims of all classes of our customers, including claims for benefits under
the Contracts.

      We will invest the assets of the Fixed Account in those assets we choose
that are allowed by applicable state insurance laws. In general, these laws
permit investments, within specified limits and subject to certain
qualifications, in federal, state and municipal obligations, corporate bonds,
preferred and common stocks, real estate mortgages, real estate and certain
other investments. We intend to invest primarily in investment-grade fixed
income securities (i.e., rated by a nationally recognized rating service within
the 4 highest grades) or instruments we believe are of comparable quality. We
are not obligated to invest amounts allocated to the Fixed Account according to
any particular strategy, except as may be required by applicable state insurance
laws. You will not have a direct or indirect interest in the Fixed Account
investments.

                           THE FIXED ACCOUNT OPTIONS:
                             THE GUARANTEE PERIODS

      You may elect one or more Guarantee Period(s) from those we make available
from time to time. We publish Guaranteed Interest Rates for each Guarantee
Period offered. We may change the Guaranteed Interest Rates we offer from time
to time, but no Guaranteed Interest Rate will ever be less than 3% per year,
compounded annually. Also, once we have accepted your allocation to a particular
Guarantee Period, we promise that the Guaranteed Interest Rate applicable to
that allocation will not change for the duration of the Guarantee Period.

      We determine Guaranteed Interest Rates at our discretion. We do not have a
specific formula for establishing the rates for different Guarantee Periods. Our
determination will be influenced by the interest rates on fixed income
investments in which we may invest with amounts allocated to the Guarantee
Periods. We will also consider other factors in determining these rates,
including regulatory and tax requirements, sales commissions and administrative
expenses borne by us, general economic trends and competitive factors. We cannot
predict the level of future interest rates.

      We may from time to time at our discretion offer interest rate specials
for new Purchase Payments that are higher than the rates we are then offering
for renewals or transfers.


      Early withdrawals from your allocation to a Guarantee Period, including
cash withdrawals, transfers, and commencement of an annuity, may be subject to a
Market Value Adjustment, which could decrease or increase the value of your
Account. See "Withdrawals, Withdrawal Charge and Market Value Adjustment."


                             THE ACCUMULATION PHASE

      During the Accumulation Phase of your Contract, you make payments into
your Account, and your earnings accumulate on a tax-deferred basis. The
Accumulation Phase begins with our acceptance of your first Purchase Payment and
ends the Business Day before your Annuity Commencement Date. The Accumulation
Phase will end sooner if you surrender your Contract or the Annuitant dies
before the Annuity Commencement Date.

ISSUING YOUR CONTRACT

      When you purchase a Contract, a completed Application and the initial
Purchase Payment are sent to us for acceptance. When we accept an Individual
Contract, we issue the Contract to you. When we accept a Group Contract, we
issue the Contract to the Owner; we issue a Certificate to you as a Participant
when we accept your Application.

      We will credit your initial Purchase Payment to your Account within 2
business days of receiving your completed Application. If your Application is
not complete, we will notify you. If we do not have

                                       14
<PAGE>
the necessary information to complete the Application within 5 business days, we
will send your money back to you or ask your permission to retain your Purchase
Payment until the Application is made complete. Then we will apply the Purchase
Payment within 2 business days of when the Application is complete.

AMOUNT AND FREQUENCY OF PURCHASE PAYMENTS

      The amount of Purchase Payments may vary; however, we will not accept an
initial Purchase Payment of less than $5,000, and each additional Purchase
Payment must be at least $1,000, unless we waive these limits. In addition, we
will not accept a Purchase Payment if your Account Value is over $1 million, or
if the Purchase Payment would cause your Account Value to exceed $1 million,
unless we have approved the Payment in advance. Within these limits, you may
make Purchase Payments at any time during the Accumulation Phase.

ALLOCATION OF NET PURCHASE PAYMENTS

      You may allocate your Purchase Payments among the different Sub-Accounts
and Guarantee Periods we offer. Over the life of your Contract, you may allocate
amounts among as many as 18 of the available investment options.

      In your Application, you may specify the percentage of each Purchase
Payment to be allocated to each Sub-Account or Guarantee Period. These
percentages are called your allocation factors. You may change the allocation
factors for future Payments by sending us written notice of the change, as
required. We will use your new allocation factors for the first Purchase Payment
we receive with or after we have received notice of the change, and for all
future Purchase Payments, until we receive another change notice.


      Although it is currently not our practice, we may deduct applicable
premium taxes or similar taxes from your Purchase Payments (see "Contract
Charges -- Premium Taxes"). In that case, we will credit your Net Purchase
Payment, which is the Purchase Payment minus the amount of those taxes.


YOUR ACCOUNT

      When we accept your first Purchase Payment, we establish an Account for
you, which we maintain throughout the Accumulation Phase of your Contract.

YOUR ACCOUNT VALUE

      Your Account Value is the sum of the value of the 2 components of your
Contract: the Variable Account portion of your Contract ("Variable Account
Value") and the Fixed Account portion of your Contract ("Fixed Account Value").
These 2 components are calculated separately, as described below under the
headings "Variable Account Value" and "Fixed Account Value".

VARIABLE ACCOUNT VALUE

      VARIABLE ACCUMULATION UNITS

      In order to calculate your Variable Account Value, we use a measure called
a Variable Accumulation Unit for each Sub-Account. Your Variable Account Value
is the sum of your Account Value in each Sub-Account, which is the number of
your Variable Accumulation Units for that Sub-Account times the value of each
Unit.

      VARIABLE ACCUMULATION UNIT VALUE

      The value of each Variable Accumulation Unit in a Sub-Account reflects the
net investment performance of that Sub-Account. We determine that value once on
each day that the New York Stock Exchange is open for trading, at the close of
trading, which is currently 4:00 p.m., Eastern Time. (The close of business is
determined by the New York Stock Exchange.) We also may determine the value of
Variable Accumulation Units of a Sub-Account on days the Exchange is closed if
there is enough

                                       15
<PAGE>
trading in securities held by that Sub-Account to materially affect the value of
the variable Accumulation Units. Each day we make a valuation is called a
"Business Day." The period that begins at the time Variable Accumulation Units
are valued on a Business Day and ends at that time on the next Business Day is
called a Valuation Period. On days other than Business Days, the value of a
Variable Accumulation Unit does not change.

      To measure these values, we use a factor -- which we call the Net
Investment Factor-- which represents the net return on the Sub-Account's assets.
At the end of any Valuation Period, the value of a Variable Accumulation Unit
for a Sub-Account is equal to the value of that Sub-Account's Variable
Accumulation Units at the end of the previous Valuation Period, multiplied by
the Net Investment Factor. We calculate the Net Investment Factor by dividing
(1) the net asset value of a Fund share held in the Sub-Account at the end of
that Valuation Period, plus the per share amount of any dividend or capital
gains distribution made by that Fund during the Valuation Period, by (2) the net
asset value per share of the Fund share at the end of the previous Valuation
Period; we then deduct a factor representing the mortality and expense risk
charge and administrative expense charge for each day in the Valuation Period.
See "Contract Charges."

      For a hypothetical example of how we calculate the value of a Variable
Accumulation Unit, see the Statement of Additional Information.

      CREDITING AND CANCELING VARIABLE ACCUMULATION UNITS

      When we receive an allocation to a Sub-Account, either from a Net Purchase
Payment or a transfer of Account Value, we credit that amount to your Account in
Variable Accumulation Units. Similarly, we cancel Variable Accumulation Units
when you transfer or withdraw amounts from a Sub-Account, or when we deduct
certain charges under the Contract. We determine the number of Units credited or
canceled by dividing the dollar amount by the Variable Accumulation Unit value
for that Sub-Account at the end of the Valuation Period during which the
transaction or charge is effective.

FIXED ACCOUNT VALUE

      Your Fixed Account value is the sum of all amounts allocated to Guarantee
Periods, either from Net Purchase Payments, transfers or renewals, plus interest
credited on those amounts, and minus withdrawals, transfers out of Guarantee
Periods, and any deductions for charges under the Contract taken from your Fixed
Account Value.

      CREDITING INTEREST

      We credit interest on amounts allocated to a Guarantee Period at the
applicable Guaranteed Interest Rate for the duration of the Guarantee Period.
The Guarantee Period begins the day we apply your allocation and ends when the
number of calendar years (or months if the Guarantee Period is less than one
year) in the Guarantee Period (measured from the end of the calendar month in
which the amount was allocated to the Guarantee Period) have elapsed. The last
day of the Guarantee Period is its Expiration Date. During the Guarantee Period,
we credit interest daily at a rate that yields the Guaranteed Interest Rate on
an annual effective basis.

      GUARANTEE AMOUNTS

      Each separate allocation you make to a Guarantee Period, together with
interest credited thereon, is called a Guarantee Amount. Each Guarantee Amount
is treated separately for purposes of determining the Market Value Adjustment. A
Guarantee Period that will extend beyond your maximum Annuity Commencement Date
will result in the application of a Market Value Adjustment upon annuitization
or withdrawal.

      RENEWALS

      We will notify you in writing between 45 and 75 days before the Expiration
Date for any Guarantee Amount. A new Guarantee Period of the same duration will
begin automatically for that

                                       16
<PAGE>
Guarantee Amount on the first day following the Expiration Date, unless before
the Expiration Date we receive:

    (1) written notice from you electing a different Guarantee Period from among
       those we then offer or

    (2) instructions to transfer all or some of the Guarantee Amount to one or
       more Sub-Accounts, in accordance with the transfer privilege provisions
       of the Contract (see "Transfer Privilege," below).

      Each new allocation to a Guarantee Period must be at least $1,000.

      A Guarantee Amount will not renew into a Guarantee Period that will extend
beyond your maximum Annuity Commencement Date. We will automatically renew your
Guarantee Amount into the next available Guarantee Period.

      EARLY WITHDRAWALS

      If you withdraw, transfer, or annuitize an allocation to a Guarantee
Period more than 30 days prior to the Expiration Date, we will apply a Market
Value Adjustment to the transaction. This could result in an increase or
decrease of your Account Value, depending on interest rates at the time. You
bear the risk that you will receive less than your principal if the Market Value
Adjustment applies.

TRANSFER PRIVILEGE

      PERMITTED TRANSFERS

      During the Accumulation Phase, you may transfer all or part of your
Account Value to one or more Sub-Accounts or Guarantee Periods then available,
subject to the following restrictions:

      -  You may not make more than 12 transfers in any Account Year;

      -  The amount transferred from a Sub-Account must be at least $1,000
         unless you are transferring your entire balance in that Sub-Account;

      -  Your Account Value remaining in a Sub-Account must be at least $1,000;

      -  The amount transferred from a Guarantee Period must be the entire
         Guarantee Amount, except for transfers of interest credited during the
         current Account Year;

      -  At least 30 days must elapse between transfers to or from Guarantee
         Periods;

      -  Transfers to or from Sub-Accounts are subject to terms and conditions
         that may be imposed by the Fund; and

      -  We impose additional restrictions on market timers, which are further
         described below.


      These restrictions do not apply to transfers made under an approved
dollar-cost averaging program.


      There is usually no charge imposed on transfers; however, we reserve the
right to impose a transfer charge of $15 for each transfer. Transfers out of a
Guarantee Period occurring more than 30 days before the Expiration Date or any
time after the Expiration Date will be subject to the Market Value Adjustment
described below. Under current law there is no tax liability for transfers.

      REQUESTS FOR TRANSFERS

      You may request transfers in writing or by telephone. The telephone
transfer privilege is available automatically, and does not require your written
election. We will require personal identifying information to process a request
for transfer made by telephone. We will not be liable for following instructions
communicated by telephone that we reasonably believe are genuine.

      If we receive your transfer request before 4:00 p.m. Eastern Time on a
Business Day, it will be effective that day. Otherwise, it will be effective the
next Business Day.

                                       17
<PAGE>
      MARKET TIMERS

      The Contracts are not designed for professional market timing
organizations or other entities using programmed and frequent transfers. If you
wish to employ such strategies, you should not purchase a Contract. Accordingly,
transfers may be subject to restrictions if exercised by a market timing firm or
any other third party authorized to initiate transfer transactions on behalf of
multiple Participants. In imposing such restrictions, we may, among other
things, not accept (1) the transfer instructions of any agent acting under a
power of attorney on behalf of more than one Participant, or (2) the transfer
instructions of individual Participants who have executed preauthorized transfer
forms that are submitted at the same time by market timing firms or other third
parties on behalf of more than one Participant. We will not impose these
restrictions unless our actions are reasonably intended to prevent the use of
such transfers in a manner that will disadvantage or potentially impair the
Contract rights of other Participants.

      In addition, some of the Funds have reserved the right to temporarily or
permanently refuse exchange requests from the Variable Account if, in the
judgment of the Fund's investment advisor, the Fund would be unable to invest
effectively in accordance with its investment objective and policies, or would
otherwise potentially be adversely affected. In particular, a pattern of
exchanges that coincide with a market timing strategy may be disruptive to a
Fund and therefore may be refused. Accordingly, the Variable Account may not be
in a position to effectuate transfers and may refuse transfer requests without
prior notice. We also reserve the right, for similar reasons, to refuse or delay
exchange requests involving transfers to or from the Fixed Account.

WAIVERS; REDUCED CHARGES; CREDITS; BONUS GUARANTEED INTEREST RATES

      We may reduce or waive the withdrawal charge or annual Account Fee, credit
additional amounts, or grant bonus Guaranteed Interest Rates in certain
situations. These situations may include sales of Contracts (1) where selling
and/or maintenance costs associated with the Contracts are reduced, such as the
sale of several Contracts to the same Participant, sales of large Contracts, and
certain group sales, and (2) to officers, directors and employees of the Company
or its affiliates, registered representatives and employees of broker-dealers
with a current selling agreement with the Company and affiliates of such
representatives and broker-dealers, employees of affiliated asset management
firms, and persons who have retired from such positions ("Eligible Employees")
and immediate family members of Eligible Employees. Eligible Employees and their
immediate family members may also purchase a Contract without regard to minimum
Purchase Payment requirements. For other situations in which withdrawal charges
may be waived, see "Withdrawals, Withdrawal Charge and Market Value Adjustment."

OPTIONAL PROGRAMS

      DOLLAR-COST AVERAGING

      Dollar-cost averaging allows you to invest gradually, over time, in up to
12 Sub-Accounts. You may select a dollar-cost averaging program at no extra
charge by allocating a minimum of $1,000 to a designated Sub-Account or to a
Guarantee Period we make available in connection with the program. Amounts
allocated to the Fixed Account under the program will earn interest at a rate
declared by the Company for the Guarantee Period you select. Previously applied
amounts may not be transferred to a Guarantee Period made available in
connection with this program. Each month or quarter, as you select, we will
transfer the same amount automatically to one or more Sub-Accounts that you
choose, up to a maximum of 12 Sub-Accounts. The program continues until your
Account Value allocated to the program is depleted or you elect to stop the
program. The final amount transferred from the Fixed Account will include all
interest earned. We do not allow transfers into any of the Guarantee Periods.


      Only Purchase Payments may be allocated to a dollar-cost averaging
program. Previously applied amounts may not be transferred to a dollar-cost
averaging program.


                                       18
<PAGE>

      No Market Value Adjustment (either positive or negative) will apply to
amounts automatically transferred from the Fixed Account under the dollar-cost
averaging program, except that if you discontinue or alter the program prior to
completion, amounts remaining in the Fixed Account will be transferred to the
MFS/Sun Life Money Market Sub-Account, unless you instruct us otherwise, and the
Market Value Adjustment will be applied. Any new allocation of a Purchase
Payment to the program will be treated as commencing a new dollar-cost averaging
program and is subject to the $1,000 minimum.


      The main objective of a dollar-cost averaging program is to minimize the
impact of short-term price fluctuations on Account Value. Since you transfer the
same dollar amount to the Sub-Accounts at set intervals, dollar-cost averaging
allows you to purchase more Variable Accumulation Units (and, indirectly, more
Fund shares) when prices are low and fewer Variable Accumulation Units (and,
indirectly, fewer Fund shares) when prices are high. Therefore, you may achieve
a lower average cost per Variable Accumulation Unit over the long term. A
dollar-cost averaging program allows you to take advantage of market
fluctuations. However, it is important to understand that a dollar-cost
averaging program does not assure a profit or protect against loss in a
declining market.

      ASSET ALLOCATION

      One or more asset allocation programs may be available in connection with
the Contracts, at no extra charge. Asset allocation is the process of investing
in different asset classes -- such as equity funds, fixed income funds and money
market funds -- depending on your personal investment goals, tolerance for risk,
and investment time horizon. By spreading your money among a variety of asset
classes, you may be able to reduce the risk and volatility of investing,
although there are no guarantees, and asset allocation does not insure a profit
or protect against loss in declining market.

      Currently, you may select one of 3 asset allocation models, each of which
represents a combination of Sub-Accounts with a different level of risk. The
available models are the conservative asset allocation model, the moderate asset
allocation model, and the aggressive asset allocation model. Each model
allocates a different percentage of Account Value to Sub-Accounts investing in
the various asset classes, with the conservative model allocating the lowest
percentage to Sub-Accounts investing in the equity asset class and the
aggressive model allocating the highest percentage to the equity asset class.
These models, as well as the terms and conditions of the asset allocation
program, are fully described in a separate brochure. Additional programs may be
available in the future.

      If you elect an asset allocation program, we will automatically allocate
your Purchase Payments among the Sub-Accounts represented in the model you
choose. By electing an asset allocation program, you authorize us to
automatically reallocate your investment options that participate in the Asset
Allocation program on a quarterly basis, or as determined by the terms of the
Asset Allocation program, to reflect the current composition of the model you
have selected, without further instruction, until we receive notification that
you wish to terminate the program, or you choose a different model.

      SYSTEMATIC WITHDRAWAL PROGRAM

      If you have an Account Value of $10,000 or more, you may select our
Systematic Withdrawal Program.

      Under the Systematic Withdrawal Program, you determine the amount and
frequency of regular withdrawals you would like to receive from your Fixed
Account Value and/or Variable Account Value and we will effect them
automatically; a Market Value Adjustment may be applicable upon withdrawal. You
may change or stop the Systematic Withdrawal Program at any time, by written
notice to us. Withdrawals under this program are subject to surrender charges.
They may also be included as income and subject to a 10% federal tax penalty.
You should consult your tax adviser before choosing this option.

      You may change or stop this program at any time, by written notice to us.

                                       19
<PAGE>
      PORTFOLIO REBALANCING PROGRAM

      Under the Portfolio Rebalancing Program, we transfer funds among the
Sub-Accounts to maintain the percentage allocation you have selected among these
Sub-Accounts. At your election, we will make these transfers on a quarterly,
semi-annual or annual basis.


      Portfolio Rebalancing does not permit transfers to or from any Guarantee
Period. `


           WITHDRAWALS, WITHDRAWAL CHARGE AND MARKET VALUE ADJUSTMENT

CASH WITHDRAWALS

      REQUESTING A WITHDRAWAL

      At any time during the Accumulation Phase you may withdraw in cash all or
any portion of your Account Value. To make a withdrawal, you must send us a
written request at our Annuity Mailing Address. Your request must specify
whether you want to withdraw the entire amount of your Account or, if less, the
amount you wish to receive.


      All withdrawals may be subject to a withdrawal charge (see "Withdrawal
Charge," below) and withdrawals from your Fixed Account Value also may be
subject to a Market Value Adjustment (see "Market Value Adjustment," below).
Upon request we will notify you of the amount we would pay in the event of a
full or partial withdrawal. Withdrawals also may have adverse federal income tax
consequences, including a 10% penalty tax (see "Tax Considerations"). You should
carefully consider these tax consequences before requesting a cash withdrawal.


      FULL WITHDRAWALS

      If you request a full withdrawal, we calculate the amount we will pay you
as follows: We start with the total value of your Account at the end of the
Valuation Period during which we receive your withdrawal request; we deduct the
Account Fee for the Account Year in which the withdrawal is made; we add or
subtract the amount of any Market Value Adjustment applicable to your Fixed
Account Value; and finally, we deduct any applicable withdrawal charge.

      A full withdrawal results in the surrender of your Contract, and
cancellation of all rights and privileges under your Contract.

      PARTIAL WITHDRAWALS

      If you request a partial withdrawal we will pay you the actual amount
specified in your request and then reduce the value of your Account by deducting
the amount paid, adding or deducting any Market Value Adjustment applicable to
amounts withdrawn from the Fixed Account, and deducting any applicable
withdrawal charge.

      You may specify the amount you want withdrawn from each Sub-Account and/or
Guarantee Period to which your Account is allocated. If you do not so specify,
we will deduct the total amount you request pro rata, based on your Account
Value at the end of the Valuation Period during which we receive your request.

      If you request a partial withdrawal that would result in your Account
Value being reduced to an amount less than the Account Fee for the Account Year
in which you make the withdrawal, we will treat it as a request for a full
withdrawal.

      TIME OF PAYMENT

      We will pay you the applicable amount of any full or partial withdrawal
within 7 days after we receive your withdrawal request, except in cases where we
are permitted to defer payment under the

                                       20
<PAGE>
Investment Company Act of 1940 and applicable state insurance law. Currently, we
may defer payment of amounts you withdraw from the Variable Account only for the
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 a
         Fund or to determine the value of the net assets of a Fund, because an
         emergency exists; and

      -  When an SEC order permits us to defer payment for the protection of
         Participants.

      We also may defer payment of amounts you withdraw from the Fixed Account
for up to six months from the date we receive your withdrawal request. We do not
pay interest on the amount of any payments we defer.

      WITHDRAWAL RESTRICTIONS FOR QUALIFIED PLANS

      If your Contract is a Qualified Contract, you should carefully check the
terms of your retirement plan for limitations and restrictions on cash
withdrawals.


      Special restrictions apply to withdrawals from Contracts used for Section
403(b) annuities (see "Tax Considerations -- Tax-Sheltered Annuities").


      When you make a withdrawal, we consider the oldest Purchase Payment that
you have not already withdrawn to be withdrawn first, then the second oldest
Purchase Payment, and so forth. Once all Purchase Payments are withdrawn, the
balance withdrawn is considered to be accumulated value.

WITHDRAWAL CHARGE

      We do not deduct any sales charge from your Purchase Payments when they
are made. However, we may impose a withdrawal charge (known as a "contingent
deferred sales charge") on certain amounts you withdraw. We impose this charge
to defray some of our expenses related to the sale of the Contracts, such as
commissions we pay to agents, the cost of sales literature, and other
promotional costs and transaction expenses.

      FREE WITHDRAWAL AMOUNT

      In each Account Year you may withdraw a portion of your Account Value --
which we call the "free withdrawal amount" -- before incurring the withdrawal
charge. For any year, the free withdrawal amount is equal to (1) 10% of the
amount of all Purchase Payments you have made during the last 7 Account Years,
including the current Account Year (the "Annual Withdrawal Allowance"), plus
(2) the amount of all Purchase Payments made before the last 7 Account Years
that you have not previously withdrawn. Any portion of the Annual Withdrawal
Allowance that you do not use in an Account Year is cumulative, that is, it is
carried forward and available for use in future years.

      For convenience, we refer to Purchase Payments made during the last 7
Account Years (including the current Account Year) as "New Payments," and all
Purchase Payments made before the last 7 Account Years as "Old Payments."

      For example, assume you wish to make a withdrawal from your Contract in
Account Year 10. You made an initial Purchase Payment of $10,000 in Account Year
1, you made one additional Purchase Payment of $8,000 in Account Year 8, and you
have made no previous withdrawals. Your Account Value in Account Year 10 is
$35,000. The free withdrawal amount for Account Year 10 is $19,400, calculated
as follows:

      -  $800, which is the Annual Withdrawal Allowance for Account Year 10 (10%
         of the $8,000 Purchase Payment made in Account Year 8, the only New
         Payment); plus

      -  $8,600, which is the total of the unused Annual Withdrawal Allowances
         of $1,000 for each of Account Years 1 through 7 and $800 for each of
         Account Years 8 and 9 that are carried forward and available for use in
         Account Year 10; plus

      -  $10,000, which is the amount of all Old Payments that you have not
         previously withdrawn.

      WITHDRAWAL CHARGE ON PURCHASE PAYMENTS

      If you withdraw more than the free withdrawal amount in any Account Year,
we consider the excess amount to be withdrawn first from New Payments that you
have not previously withdrawn. We impose the withdrawal charge on the amount of
these New Payments. Thus, the maximum amount on which we will impose the
withdrawal charge in any year will never be more than the total of all New
Payments that you have not previously withdrawn.

      The amount of your withdrawal, if any, that exceeds the total of the free
withdrawal amount plus the aggregate amount of all New Payments not previously
withdrawn, is not subject to the withdrawal charge.

      ORDER OF WITHDRAWAL

      New Payments are withdrawn on a first-in first-out basis until all New
Payments have been withdrawn. For example, assume the same facts as in the
example above. In Account Year 10 you wish to withdraw $25,000. We attribute the
withdrawal first to the free withdrawal amount of $19,400, which is not subject
to the withdrawal charge. The remaining $5,600 is withdrawn from the Purchase
Payment made in Account Year 8 (the only New Payment) and is subject to the
withdrawal charge. The $2,400 balance of the Account Year 8 Purchase Payment
will remain in your Account. If you make a subsequent $5,000 withdrawal in
Account Year 10, $2,400 of that amount will be withdrawn from the remainder of
the Account Year 8 Purchase Payment and will be subject to the withdrawal
charge. The other $2,600 of your withdrawal (which exceeds the amount of all New
Payments not previously withdrawn) will not be subject to the withdrawal charge.

      CALCULATION OF WITHDRAWAL CHARGE


      We calculate the amount of the withdrawal charge by multiplying the
Purchase Payments you withdraw by a percentage. The percentage varies according
to the number of Account Years the Purchase Payment has been held in your
Account, including the year in which you made the Payment, but not the year you
withdraw it. Each Payment begins a new seven-year period and moves down a
declining surrender charge scale at each Contract Anniversary. Payments received
during the current Contract Year will be charged 6% if withdrawn. On your next
scheduled Contract Anniversary, that Payment, along with any other Payments made
during that Contract Year, will be considered to be in their second Contract
Year and will have a 5% withdrawal charge. On the next Contract Anniversary,
these Payments will move into their third Contract Year and will have a
withdrawal charge of 5%, if withdrawn. The withdrawal charge decreases according
to the number of Contract Years the Purchase Payment has been in your Account.
The declining scale is as follows:



<TABLE>
<CAPTION>
  NUMBER OF
ACCOUNT YEARS
  PURCHASE
   PAYMENT
 HAS BEEN IN    WITHDRAWAL
YOUR ACCOUNT      CHARGE
- -------------   ----------
<S>             <C>
 0-1                6%
 2-3                5%
 4-5                4%
 6                  3%
 7 or more          0%
</TABLE>


      The withdrawal charge will never be greater than 6% of the aggregate
amount of Purchase Payments you make under the Contract.

      For a Group Contract, we may modify the withdrawal charges and limits,
upon notice to the Owner of the Group Contract. However, any modification will
only apply to Accounts established after the date of the modification.

      For additional examples of how we calculate withdrawal charges, see
Appendix C.

                                       22
<PAGE>
      TYPES OF WITHDRAWALS NOT SUBJECT TO WITHDRAWAL CHARGE

      We do not impose a withdrawal charge on withdrawals from the Accounts of
(a) our employees, (b) employees of our affiliates, or (c) licensed insurance
agents who sell the Contracts. We also may waive withdrawal charges with respect
to Purchase Payments derived from the surrender of other annuity contracts we
issue.

      If approved in your state, we will waive the withdrawal charge for a full
withdrawal if (a) at least one year has passed since we issued your Contract and
(b) you are confined to an eligible nursing home and have been confined there
for at least the preceding 180 days, or any shorter period required by your
state. An "eligible nursing home" means a licensed hospital or licensed skilled
or intermediate care nursing facility at which medical treatment is available on
a daily basis and daily medical records are kept for each patient. You must
provide us evidence of confinement in the form we determine.

      We do not impose the withdrawal charge on amounts you apply to provide an
annuity, amounts we pay as a death benefit, or amounts you transfer among the
Sub-Accounts, between the Sub-Accounts and the Fixed Account, or within the
Fixed Account.

MARKET VALUE ADJUSTMENT


      We will apply a Market Value Adjustment if you withdraw or transfer
amounts from your Fixed Account Value more than 30 days before the end of the
applicable Guarantee Period. For this purpose, using Fixed Account Value to
provide an annuity is considered a withdrawal, and the Market Value Adjustment
will apply. However, we will not apply the Market Value Adjustment to automatic
transfers to a Sub-Account from a Guarantee Period as part of our dollar-cost
averaging program.


      We apply the Market Value Adjustment separately to each Guarantee Amount
in the Fixed Account, that is to each separate allocation you have made to a
Guarantee Period together with interest credited on that allocation. However, we
do not apply the adjustment to the amount of interest credited during your
current Account Year. Any withdrawal from a Guarantee Amount is attributed first
to such interest.

      A Market Value Adjustment may decrease, increase or have no effect on your
Account Value. This will depend on changes in interest rates since you made your
allocation to the Guarantee Period and the length of time remaining in the
Guarantee Period. In general, if the Guaranteed Interest Rate we currently
declare for Guarantee Periods equal to the balance of your Guarantee Period (or
your entire Guarantee Period for Guarantee Periods of less than one year) is
higher than your Guaranteed Interest Rate, the Market Value Adjustment is likely
to decrease your Account Value. If our current Guaranteed Interest Rate is
lower, the Market Value Adjustment is likely to increase your Account Value.

      We determine the amount of the Market Value Adjustment by multiplying the
amount that is subject to the adjustment by the following formula:

<TABLE>
<C> <S>       <C> <C>       <C>
                  N/12
    1 + I
  ( --------  )             -1
    1 + J
</TABLE>

where:

      I is the Guaranteed Interest Rate applicable to the Guarantee Amount from
which you withdraw, transfer or annuitize;

      J is the Guaranteed Interest Rate we declare at the time of your
withdrawal, transfer or annuitization for Guarantee Periods equal to the length
of time remaining in the Guarantee Period applicable to your Guarantee Amount,
rounded to the next higher number of complete years, for Guarantee Periods of
one year or more. For any Guarantee Periods of less than one year, J is the
Guaranteed Interest Rate we declare at the time of your withdrawal, transfer or
annuitization for a Guarantee Period of the same length as your Guarantee
Period. If, at that time, we do not offer the applicable Guarantee Period we
will use an interest rate determined by straight-line interpolation of the
Guaranteed Interest Rates for the Guarantee Periods we do offer); and

                                       23
<PAGE>
      N is the number of complete months remaining in your Guarantee Period.

      We will apply the Market Value Adjustment to the amount being withdrawn
after deduction of any Account Fee, if applicable, but before we impose any
withdrawal charge on the amount withdrawn.

      For examples of how we calculate the Market Value Adjustment, see Appendix
C.

                                CONTRACT CHARGES

ACCOUNT FEE


      During the Accumulation Phase of your Contract, we will deduct from your
Account an annual Account Fee to help cover the administrative expenses we incur
related to the issuance of Contracts and the maintenance of Accounts. We deduct
the Account Fee on each Account Anniversary, which is the anniversary of the
first day of the month after we issue your Contract. In Account Years 1 through
5, the Account Fee is equal to the lesser of $30 or 2% of your Account Value.
After Account Year 5, we may change the Account Fee each year, but the Account
Fee will never exceed the lesser of $50 or 2% of your Account Value. We deduct
the Account Fee pro rata from each Sub-Account and each Guarantee Period, based
on the allocation of your Account Value on your Account Anniversary.



      We will not charge the annual Account Fee if:


      (1)  your Account has been allocated only to the Fixed Account during the
           applicable Account Year; or

      (2)  your Account Value is more than $75,000 on your Account Anniversary.

      If you make a full withdrawal of your Account, we will deduct the full
amount of the Account Fee at the time of the withdrawal. In addition, on the
Annuity Commencement Date we will deduct a pro rata portion of the Account Fee
to reflect the time elapsed between the last Account Anniversary and the day
before the Annuity Commencement Date.


      After the Annuity Commencement Date, we will deduct an annual Account Fee
of $30 in the aggregate in equal amounts from each Variable Annuity payment we
make during the year. We do not deduct any Account Fee from Fixed Annuity
payments.


ADMINISTRATIVE EXPENSE CHARGE

      We deduct an administrative expense risk charge from the assets of the
Variable Account at an annual effective rate equal to 0.15% during both the
Accumulation Phase and the Income Phase. This charge is designed to reimburse us
for expenses we incur in administering the Contracts, the Accounts and the
Variable Account that are not covered by the annual Account Fee.

MORTALITY AND EXPENSE RISK CHARGE


      During both the Accumulation Phase and the Income Phase, we deduct a
mortality and expense risk charge from the assets of the Variable Account at an
effective annual rate equal to 1.25%. The mortality risk we assume arises from
our contractual obligation to continue to make annuity payments to each
Annuitant, regardless of how long the Annuitant lives and regardless of how long
all Annuitants as a group live. This obligation assures each Annuitant that
neither the longevity of fellow Annuitants nor an improvement in life expectancy
generally will have an adverse effect on the amount of any annuity payment
received under the Contract. The mortality risk also arises from our contractual
obligation to pay a death benefit upon the death of the Annuitant prior to the
Annuity Commencement Date. The expense risk we assume is the risk that the
Account Fee and the administrative expense charge we assess under the Contracts
may be insufficient to cover the actual total administrative expenses we incur.
If the amount of the charge is insufficient to cover the mortality and expense
risks, we will bear the loss. If the amount of the charge is more than
sufficient to cover the risks, we will make a profit on the charge. We may use
this profit for any proper corporate purpose, including the payment of marketing
and distribution expenses for the Contracts.


                                       24
<PAGE>
PREMIUM TAXES

      Some states and local jurisdictions impose a premium tax on us that is
equal to a specified percentage of the Purchase Payments you make. In many
states there is no premium tax. We believe that the amounts of applicable
premium taxes currently range from 0% to 3.5%. You should consult a tax adviser
to find out if your state imposes a premium tax and the amount of any tax.

      In order to reimburse us for the premium tax we may pay on Purchase
Payments, our policy is to deduct the amount of such taxes from the amount you
apply to provide an annuity at the time of annuitization. However, we reserve
the right to deduct the amount of any applicable tax from your Account at any
time, including at the time you make a Purchase Payment or make a full or
partial withdrawal. We do not make any profit on the deductions we make to
reimburse premium taxes.

FUND EXPENSES

      There are fees and charges deducted from each Fund. These fees and
expenses are described in the Fund's prospectus and related Statement of
Additional Information.

MODIFICATION IN THE CASE OF GROUP CONTRACTS


      For Group Contracts, we may modify the annual Account Fee, the
administrative expense charge and the mortality and expense risk charge upon
notice to Owners. However, such modification will apply only with respect to
Participant Accounts established after the effective date of the modification.


                                 DEATH BENEFIT

      If the Annuitant dies during the Accumulation Phase, we will pay a death
benefit to your Beneficiary, using the payment method elected -- a single cash
payment or one of our Annuity Options. (If you have named more than one
Annuitant, the death benefit will be payable after the death of the last
surviving of the Annuitants.) If the Beneficiary is not living on the date of
death, we will pay the death benefit in one sum to you or to your estate if you
are the Annuitant. We do not pay a death benefit if the Annuitant dies during
the Income Phase. However, the Beneficiary will receive any payments provided
under an Annuity Option that is in effect.

SPOUSAL CONTINUANCE


      If your spouse is your Beneficiary, upon your death (if you are the
Annuitant) your spouse may elect to continue the Contract as the Participant,
rather than receive the death benefit. In that case, the death benefit
provisions of the Contract will not apply until the death of your spouse (see
"Other Contract Provisions -- Death of Participant").


AMOUNT OF DEATH BENEFIT

      To calculate the amount of your death benefit, we use a "Death Benefit
Date." The Death Benefit Date is the date we receive proof of the Annuitant's
death in an acceptable form ("Due Proof of Death") if you have elected a death
benefit payment method before the Annuitant's death and it remains effective.
Otherwise, the Death Benefit Date is the later of the date we receive Due Proof
of Death or the date we receive either the Beneficiary's election of payment
method, or if you were the Annuitant and the Beneficiary is your spouse, the
Beneficiary's election to continue the Contract. If we do not receive the
Beneficiary's election within 60 days after we receive Due Proof of Death, the
Death Benefit Date will be the last day of the 60 day period.

      The amount of the death benefit is determined as of the Death Benefit
Date.

                                       25
<PAGE>
      If the Annuitant was 85 or younger on your Contract Date (the date we
accepted your first Purchase Payment), the death benefit will be the greatest of
the following amounts:

      1.  Your Account Value for the Valuation Period during which the Death
          Benefit Date occurs;

      2.  The amount we would pay if you had surrendered your entire Account on
          the Death Benefit Date;

      3.  Your Account Value on the Seven-Year Anniversary immediately before
          the Death Benefit Date, adjusted for subsequent Purchase Payments and
          partial withdrawals and charges made between the Seven-Year
          Anniversary and the Death Benefit Date;

      4.  Your total Purchase Payments minus the sum of partial withdrawals;
          interest will accrue daily on each Purchase Payment and each partial
          withdrawal at a rate equivalent to a rate of 5% per year until the
          first day of the month following the Annuitant's 80th birthday, or
          until the Purchase Payment or partial withdrawal has doubled in
          amount, whichever is earlier.

      If the Annuitant was 86 or older on your Contract Date, the death benefit
is equal to amount (2) above; because this amount will reflect any applicable
withdrawal charges and Market Value Adjustment, it may be less than your Account
Value.

      If the death benefit we pay is amount (2), (3) or (4), your Account Value
will be increased by the excess, if any, of that amount over amount (1). Any
such increase will be allocated to the Sub-Accounts in proportion to your
Account Value in those Sub-Accounts on the Death Benefit Date. Also, any portion
of this new Account Value attributed to the Fixed Account will be transferred to
the MFS/Sun Life Money Market Sub-Account (without the application of a Market
Value Adjustment). The Beneficiary may then transfer to the Fixed Account and
begin a new Guarantee Period.

METHOD OF PAYING DEATH BENEFIT


      The death benefit may be paid in a single cash payment or as an annuity
(either fixed, variable or a combination), under one or more of our Annuity
Options. We describe the Annuity Options in this Prospectus under "The Income
Phase -- Annuity Provisions."


      During the Accumulation Phase, you may elect the method of payment for the
death benefit. If no such election is in effect on the date of the Annuitant's
death, the Beneficiary may elect either a single cash payment or an annuity. If
you were the Annuitant and the Beneficiary is your spouse, the Beneficiary may
elect to continue the Contract. These elections are made by sending us at our
Annuity Mailing Address a completed election form, which we will provide. If we
do not receive the Beneficiary's election within 60 days after we receive Due
Proof of Death, we will pay the death benefit in a single cash payment.

      If we pay the death benefit in the form of an Annuity Option, the
Beneficiary becomes the Annuitant/Payee under the terms of that Annuity Option
(see "The Income Phase -- Annuity Provisions").

      Neither you nor the Beneficiary may exercise rights that would adversely
affect the treatment of the Contract as an annuity contract under the Internal
Revenue Code. (See "Other Contract Provisions -- Death of Participant.")

SELECTION AND CHANGE OF BENEFICIARY

      You select your Beneficiary in your 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.

PAYMENT OF DEATH BENEFIT

      Payment of the death benefit in cash will be made within 7 days of the
Death Benefit Date, except if we are permitted to defer payment in accordance
with the Investment Company Act of 1940. If an Annuity Option is elected, the
Annuity Commencement Date will be the first day of the second

                                       26
<PAGE>
calendar month following the Death Benefit Date, and your Account will remain in
effect until the Annuity Commencement Date.

DUE PROOF OF DEATH

      We accept any of the following as proof of any person's death:

      -  An original certified copy of an official death certificate;

      -  An original certified copy of a decree of a court of competent
         jurisdiction as to the finding of death; or

      -  Any other proof we find satisfactory.

                     THE INCOME PHASE -- ANNUITY PROVISIONS

      During the Income Phase, we make regular monthly payments to the
Annuitant.

      The Income Phase of your Contract begins with the Annuity Commencement
Date. On that date, we apply your Account Value, adjusted as described below,
under the Annuity Option(s) you have selected, and we make the first annuity
payment.


      Once the Income Phase begins, no lump sum settlement option or cash
withdrawals are permitted, except pursuant to Annuity Option D, Monthly Payments
for a Specified Period Certain, as described below under the heading "Annuity
Options," and you cannot change the Annuity Option(s) selected. You may request
a full withdrawal before the Annuity Commencement Date, which will be subject to
all charges applicable on withdrawals (see "Withdrawals, Withdrawal Charge and
Market Value Adjustment").


SELECTION OF THE ANNUITANT OR CO-ANNUITANT

      You select the Annuitant in your Application. The Annuitant is the person
who receives annuity payments during the Income Phase and on whose life these
payments are based. In your Contract, the Annuity Options refer to the Annuitant
as the "Payee."

      Under a Non-Qualified Contract, if you name someone other than yourself as
Annuitant, you may also select a Co-Annuitant, who will become the new Annuitant
if the original Annuitant dies before the Income Phase. If you have named both
an Annuitant and a Co-Annuitant, you may designate one of them to become the
sole Annuitant as of the Annuity Commencement Date, if both are living at that
time. If you have not made that designation on the 30th day before the Annuity
Commencement Date, and both the Annuitant and the Co-Annuitant are still living,
the Co-Annuitant will become the Annuitant on the Annuity Commencement Date.

      When an Annuity Option has been selected as the method of paying the death
benefit, the Beneficiary is the Payee of the annuity payment.

SELECTION OF THE ANNUITY COMMENCEMENT DATE

      You select the Annuity Commencement Date in your Application. The
following restrictions apply to the date you may select:

      -  The earliest possible Annuity Commencement Date is the first day of the
         second month following your Contract Date.

      -  The latest possible Annuity Commencement Date is the first day of the
         month following the Annuitant's 90th birthday or, if there is a
         Co-Annuitant, the 90th birthday of the younger of the Annuitant and
         Co-Annuitant.

      -  The Annuity Commencement Date must always be the first day of a month.

                                       27
<PAGE>
      You may change the Annuity Commencement Date from time to time by sending
us written notice, with the following additional limitations:

      -  We must receive your notice at least 30 days before the current Annuity
         Commencement Date.

      -  The new Annuity Commencement Date must be at least 30 days after we
         receive the notice.

      There may be other restrictions on your selection of the Annuity
Commencement Date imposed by your retirement plan or applicable law. For
example, in most situations, current law requires that for a Qualified Contract,
certain minimum distributions must commence 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).

ANNUITY OPTIONS

      We offer the following Annuity Options for payments during the Income
Phase. Each Annuity Option may be selected for a Variable Annuity, a Fixed
Annuity, or a combination of both, except that Annuity Option E is available
only for a Fixed Annuity. We may also agree to other settlement options, at our
discretion.

      ANNUITY OPTION A -- LIFE ANNUITY

      We provide monthly payments during the lifetime of the Annuitant. Annuity
payments stop when the Annuitant dies. There is no provision for continuation of
any payments 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 Annuitant. In
addition, we guarantee that the Beneficiary will receive monthly payments for
the remainder of the period certain, if the Annuitant dies during that period.
The election of a longer period results in smaller monthly payments. If no
Beneficiary is designated, we pay the discounted value of the remaining payments
in one sum to the Annuitant's estate. The Beneficiary may also elect to receive
the discounted value of the remaining payments in one sum. The discount rate for
a Variable Annuity will be the assumed interest rate in effect; the discount
rate for a Fixed Annuity will be based on the interest rate we used to determine
the amount of each payment.

      ANNUITY OPTION C -- JOINT AND SURVIVOR ANNUITY

      We make monthly payments during the lifetime of the Annuitant and another
person you designate and during the lifetime of the survivor of the two. We stop
making payments when the survivor dies. There is no provision for continuance of
any payments to a Beneficiary.

      ANNUITY OPTION D -- MONTHLY PAYMENTS FOR A SPECIFIED PERIOD CERTAIN


      We make monthly payments for a specified period of time from 5 to 30
years, as you elect. If payments under this option are paid on a Variable
Annuity basis, the Annuitant may elect to receive some or all of the discounted
value of the remaining payments, less any applicable withdrawal charge; the
discount rate for this purpose will be the assumed interest rate in effect. If
the Annuitant dies during the period selected, the remaining income payments are
made as described under Annuity Option B. The election of this Annuity Option
may result in the imposition of a penalty tax.


      ANNUITY OPTION E -- FIXED PAYMENTS

      We hold the portion of your Adjusted Account Value selected for this
option at interest, and make fixed payments in such amounts and at such times as
you and we may agree. We continue making payments until the amount we hold is
exhausted. The final payment will be for the remaining balance and may be less
than the previous installments. We will credit interest yearly on the amount
remaining unpaid at a rate we determine from time to time, but never less than
3% per year (or a higher rate if

                                       28
<PAGE>
specified in your Contract), compounded annually. We may change the rate at any
time, but will not reduce it more frequently than once each calendar year. The
election of this Annuity Option may result in the imposition of a penalty tax.

SELECTION OF ANNUITY OPTION

      You select one or more of the Annuity Options, which you may change from
time to time during the Accumulation Phase, as long as we receive your selection
or change in writing at least 30 days before the Annuity Commencement Date. If
we have not received your written selection on the 30th day before the Annuity
Commencement Date, you will receive Annuity Option B, for a life annuity with
120 monthly payments certain.

      You may specify the proportion of your Adjusted Account Value you wish to
provide a Variable Annuity or a Fixed Annuity. Under a Variable Annuity, the
dollar amount of payments will vary, while under a Fixed Annuity, the dollar
amount of annuity payments will remain the same. If you do not specify a
Variable Annuity or a Fixed Annuity, your Adjusted Account Value will be divided
between Variable and Fixed Annuities in the same proportions as your Account
Value was divided between the Variable and Fixed Accounts on the Annuity
Commencement Date. You may allocate your Adjusted Account Value applied to a
Variable Annuity among the Sub-Accounts, or we will use your existing
allocations.

      There may be additional limitations on the options you may elect under
your particular retirement plan or applicable law.

      REMEMBER THAT THE ANNUITY OPTIONS MAY NOT BE CHANGED ONCE ANNUITY PAYMENTS
BEGIN.

AMOUNT OF ANNUITY PAYMENTS

      ADJUSTED ACCOUNT VALUE

      The Adjusted Account Value is the amount we apply to provide a Variable
Annuity and/or a Fixed Annuity. We calculate Adjusted Account Value by taking
your Account Value on the Business Day immediately prior to the Annuity
Commencement Date and making the following adjustments:

      -  We deduct a proportional amount of the annual Account Fee, based on the
         fraction of the current Account Year that has elapsed;

      -  If applicable, we apply the Market Value Adjustment to your Account
         Value in the Fixed Account, which may result in a deduction, an
         addition, or no change to your Account Value; and

      -  We deduct any applicable premium tax or similar tax if not previously
         deducted.

      VARIABLE ANNUITY PAYMENTS


      Variable Annuity payments may vary each month. We determine the dollar
amount of the first payment using the portion of your Adjusted Account Value
applied to a Variable Annuity and the Annuity Payment Rates in your Contract,
which are based on an assumed interest rate of 3% per year, compounded annually
(see "Annuity Payment Rates").


      To calculate the remaining payments, we convert the amount of the first
payment into Annuity Units for each Sub-Account; we determine the number of
those Annuity Units by dividing the portion of the first payment attributable to
the Sub-Account by the Annuity Unit Value of that Sub-Account for the Valuation
Period ending just before the Annuity Commencement Date. This number of Annuity
Units for each Sub-Account will remain constant (unless the Annuitant requests
an exchange of Annuity Units). However, the dollar amount of the next Variable
Annuity payment -- which is the sum of the number of Annuity Units for each
Sub-Account times its Annuity Unit Value for the Valuation Period ending just
before the date of the payment -- will increase, decrease, or remain the same,
depending on the net investment return of the Sub-Accounts.

                                       29

      If the net investment return of the Sub-Accounts selected is the same as
the assumed interest rate of 3%, compounded annually, the payments will remain
level. If the net investment return exceeds the assumed interest rate, payments
will increase and, conversely, if it is less than the assumed interest rate,
payments will decrease.

      Please refer to the Statement of Additional Information for more
information about calculating Variable Annuity Units and Variable Annuity
payments, including examples of these calculations.

      FIXED ANNUITY PAYMENTS


      Fixed Annuity payments are the same each month. We determine the dollar
amount of each Fixed Annuity payment using the fixed portion of your Adjusted
Account Value and the applicable Annuity Payment Rates. These will be either
(1) the rates in your Contract, which are based on a minimum guaranteed interest
rate of 3% per year, compounded annually, or (2) new rates we have published and
are using on the Annuity Commencement Date, if they are more favorable (see
"Annuity Payment Rates").


      MINIMUM PAYMENTS

      If your Adjusted Account Value is less than $2,000, or the first annuity
payment for any Annuity Option is less than $20, we will pay the Adjusted
Account Value to the Annuitant in one payment.

EXCHANGE OF VARIABLE ANNUITY UNITS

      During the Income Phase, the Annuitant may exchange Annuity Units from one
Sub-Account to another, up to 12 times each Account Year. To make an exchange,
the Annuitant sends us, at our Annuity Mailing Address, a written request
stating the number of Annuity Units in the Sub-Account he or she wishes to
exchange and the new Sub-Account for which Annuity Units are requested. The
number of new Annuity Units will be calculated so the dollar amount of an
annuity payment on the date of the exchange would not be affected. To calculate
this number, we use Annuity Unit values for the Valuation Period during which we
receive the exchange request.

      Before exchanging Annuity Units from one Sub-Account to another, the
Annuitant should carefully review the Fund prospectuses for the investment
objectives and risk disclosure of the Funds in which the Sub-Accounts invest.

      During the Income Phase, we permit only exchanges among Sub-Accounts. No
exchanges to or from a Fixed Annuity are permitted.

ACCOUNT FEE

      During the Income Phase, we deduct the annual Account Fee of $30 in equal
amounts from each Variable Annuity payment. We do not deduct the annual Account
Fee from Fixed Annuity payments.

ANNUITY PAYMENT RATES


      The Contract contains Annuity Payment Rates for each Annuity Option
described in this Prospectus. 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 specified in the applicable Contract (at least 3% per
year, compounded annually); and (b) the monthly Fixed Annuity payment, when this
payment is based on the minimum guaranteed interest rate specified in the
Contract (at least 3% per year, compounded annually). We may change these rates
under Group Contracts for Accounts established after the effective date of such
change (see "Other Contract Provisions -- Modification").


      The Annuity Payment Rates may vary according to the Annuity Option(s)
elected and the adjusted age of the Annuitant. The Contract also describes the
method of determining the adjusted age of the Annuitant. The mortality table
used in determining the Annuity Payment Rates for Options A, B and C is the 1983
Individual Annuitant Mortality Table.

                                       30

ANNUITY OPTIONS AS METHOD OF PAYMENT FOR DEATH BENEFIT

      You or your Beneficiary may also select one or more Annuity Options to be
used in the event of your death before the Income Phase, as described under the
"Death Benefit" section of this Prospectus. In that case, your Beneficiary will
be the Annuitant/Payee. The Annuity Commencement Date will be the first day of
the second month beginning after the Death Benefit Date.

                           OTHER CONTRACT PROVISIONS

EXERCISE OF CONTRACT RIGHTS

      A Group Contract belongs to the Owner. In the case of a Group Contract,
the Owner may expressly reserve all Contract rights and privileges; otherwise,
each Participant will be entitled to exercise such rights and privileges. In any
case, such rights and privileges can be exercised 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 before the Annuity Commencement Date, except as the Contract
otherwise provides.

      The Annuitant becomes the Payee on and after the Annuity Commencement
Date. The Beneficiary becomes the Payee on the death of the Annuitant after the
Annuity Commencement Date. Such Payee may thereafter exercise such rights and
privileges, if any, of ownership which continue.

CHANGE OF OWNERSHIP

      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 the Qualified Contract after
transfer 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 or custodian of an individual retirement account plan qualified
under Section 408 of the Internal Revenue Code for the benefit of the
Participants under a Group Contract; 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 prior to the last Annuity Commencement Date, and each Participant, in
like manner, may change the ownership interest in a Contract. A change of
ownership will not be binding on us until we receive written notification. When
we receive such notification, the change will be effective as of the date on
which the request for change was signed by the Owner or Participant, as
appropriate, but the change will be without prejudice to us on account of any
payment we make or any action we take before receiving the change. If you change
the Owner of a Non-Qualified Contract, you will become immediately liable for
the payment of taxes on any gain realized under the Contract prior to the change
of ownership, including possible liability for a 10% federal excise tax.

DEATH OF PARTICIPANT

      If your Contract is a Non-Qualified Contract and you die prior to the
Annuitant and before the Annuity Commencement Date, special distribution rules
apply. In that case, your Account Value, plus or minus any Market Value
Adjustment, must be distributed to your "designated beneficiary" within the
meaning of Section 72(s) of the Internal Revenue Code, either (1) as a lump sum
within 5 years after your death or (2) if in the form of an annuity, over a
period not greater than the life or expected life of the designated beneficiary,
with payments beginning no later than one year after your death.

      The person you have named as Beneficiary under your Contract, if any, will
be the "designated beneficiary." If the named Beneficiary is not living, the
Annuitant automatically becomes the designated beneficiary.

                                       31
<PAGE>
      If the designated beneficiary is your surviving spouse, your spouse may
elect to continue the Contract in his or her own name as Participant. If you
were the Annuitant as well as the Participant, your surviving spouse (if the
designated beneficiary) may elect to be named as both Participant and Annuitant
and continue the Contract; in that case, we will not pay a death benefit and the
Account Value will not be increased to reflect the death benefit calculation. In
all other cases where you are the Annuitant, the death benefit provisions of the
Contract control, subject to the condition that any Annuity Option elected
complies with the special distribution requirements described above.

      If your spouse elects to continue the Contract (either in the case where
you are the Annuitant or in the case where you are not the Annuitant), your
spouse must give us written notification within 60 days after we receive Due
Proof of Death, and the special distributioon rules described above will apply
on the death of your spouse.

      If you are the Annuitant and you die during the Income Phase, the
remaining value of the Annuity Option in place must be distributed at least as
rapidly as the method of distribution under the option.

      If the Participant is not a natural person, these distribution rules apply
on a change in, or the death of, any Annuitant or Co-Annuitant.

      Payments made in contravention of these special rules would adversely
affect the treatment of the Contracts as annuity contracts under the Internal
Revenue Code. Neither you nor the Beneficiary may exercise rights that would
have that effect.

      If yours is a Qualified Contract, any distributions upon your death 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 FUND SHARES

      We will vote Fund shares held by the Sub-Accounts at meetings of
shareholders of the Funds or in connection with similar solicitations, but will
follow voting instructions received from persons having the right to give voting
instructions. During the Accumulation Phase, you will have the right to give
voting instructions, except in the case of a Group Contract where the Owner has
reserved this right. During the Income Phase, the Payee -- that is the Annuitant
or Beneficiary entitled to receive benefits -- is the person having such voting
rights. We will vote any shares attributable to us and Fund shares for which no
timely voting instructions are received in the same proportion as the shares for
which we receive instructions from Owners, Participants and Payees, as
applicable.

      Owners of Qualified Contracts issued on a group basis may be subject to
other voting provisions of the particular plan and of the Investment Company Act
of 1940. Employees who contribute to plans that are funded by the Contracts may
be entitled to instruct the Owners as to how to instruct us to vote the 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. If no voting instructions are received
from any such person with respect to a particular Participant Account, the Owner
may instruct the Company as to how to vote the number of Fund shares for which
instructions may be given.

      Neither the Variable Account nor the Company is under any duty to provide
information concerning the voting instruction rights of persons who may have
such rights under plans, other than rights afforded by the Investment Company
Act of 1940, or any duty to inquire as to the instructions received or the
authority of Owners, Participants or others, as applicable, to instruct the
voting of Fund shares. Except as the Variable Account or the Company has actual
knowledge to the contrary, the instructions given by Owners under Group
Contracts and Payees will be valid as they affect the Variable Account, the
Company and any others having voting instruction rights with respect to the
Variable Account.

      All Fund proxy material, together with an appropriate form to be used to
give voting instructions, will be provided to each person having the right to
give voting instructions at least 10 days prior to each meeting of the
shareholders of the Fund. We will determine the number of Fund shares as to

                                       32
<PAGE>
which each such person is entitled to give instructions as of the record date
set by the Fund for such meeting which is expected to be not more than 90 days
prior to each such meeting. Prior to the Annuity Commencement Date, the number
of Fund shares as to which voting instructions may be given to the Company is
determined by dividing the value of all of the Variable Accumulation Units of
the particular Sub-Account credited to the Participant Account by the net asset
value of one Fund share as of the same date. On or after the Annuity
Commencement Date, the number of Fund shares as to which such instructions may
be given by a Payee is determined by dividing the reserve held by the Company in
the Sub-Account with respect to the particular Payee by the net asset value of a
Fund share as of the same date. After the Annuity Commencement Date, the number
of Fund shares as to which a Payee is entitled to give voting instructions will
generally decrease due to the decrease in the reserve.

PERIODIC REPORTS

      During the Accumulation Period we will send you, or such other person
having voting rights, at least once during each Account Year, a statement
showing the number, type and value of Accumulation Units credited to your
Account and the Fixed Accumulation Value of your Account, which statement shall
be accurate as of a date not more than 2 months previous to the date of mailing.
These periodic statements contain important information concerning your
transactions with respect to a Contract. It is your obligation to review each
such statement carefully and to report to us, at the address or telephone number
provided on the statement, any errors or discrepancies in the information
presented therein within 60 days of the date of such statement. Unless we
receive notice of any such error or discrepancy from you within such period, we
may not be responsible for correcting the error or discrepancy.

      In addition, every person having voting rights will receive such reports
or prospectuses concerning the Variable Account and the Funds as may be required
by the Investment Company Act of 1940 and the Securities Act of 1933. We will
also send such statements reflecting transactions in your Account as may be
required by applicable laws, rules and regulations.

      Upon request, we will provide you with information regarding fixed and
variable accumulation values.

SUBSTITUTION OF SECURITIES

      Shares of any or all Funds may not always be available for investment
under the Contract. We may add or delete Funds or other investment companies as
variable investment options under the Contracts. We may also substitute shares
of another registered open-end investment company or unit investment trust for
the shares held in any Sub-Account, provided that the substitution has been
approved, if required, by the SEC. In the event of any substitution pursuant to
this provision, we may make appropriate endorsement to the Contract to reflect
the substitution.

CHANGE IN OPERATION OF VARIABLE ACCOUNT

      At our election and subject to any necessary vote by persons having the
right to give instructions with respect to the voting of 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 SEC. In the
event of any change in the operation of the Variable Account pursuant to this
provision, we may make appropriate endorsement to the Contract to reflect the
change and take such other action as we deem necessary and appropriate to effect
the change.

SPLITTING UNITS

      We reserve the right to split or combine the value of Variable
Accumulation Units, Annuity Units or any of them. In effecting any such change
of unit values, strict equity will be preserved and no change will have a
material effect on the benefits or other provisions of the Contracts.

                                       33
<PAGE>
MODIFICATION


      Upon notice to the Participant, in the case of an Individual Contract, and
the Owner and Participant(s), in the case of a Group Contract (or the Payee(s)
during the Income Phase), we may modify the Contract 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 the Company or the
Variable Account is subject; (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; (iii) is necessary to
reflect a change in the operation of the Variable Account or the Sub-Account(s)
(see "Change in Operation of Variable Account"); (iv) provides additional
Variable Account and/or fixed accumulation options; or (v) as may otherwise be
in the best interests of Owners, Participants, or Payees, as applicable. In the
event of any such modification, we may make appropriate endorsement in the
Contract to reflect such modification.


      In addition, upon notice to the Owner, we may modify a Group Contract to
change the withdrawal charges, Account Fees, mortality and expense risk charges,
administrative expense charges, the tables used in determining the amount of the
first monthly variable annuity and fixed annuity payments and the formula used
to calculate the Market Value Adjustment, provided that such modification
applies only to Participant Accounts established after the effective date of
such modification. In order to exercise our modification rights in these
particular instances, we must notify the Owner of such modification in writing.
The notice shall specify the effective date of such modification which must be
at least 60 days following the date we mail notice of modification. All of the
charges and the annuity tables which are provided in the Group Contract prior to
any such modification will remain in effect permanently, unless improved by the
Company, with respect to Participant Accounts established prior to the effective
date of such modification.

LIMITATION OR DISCONTINUANCE OF NEW PARTICIPANTS

      We may limit or discontinue the acceptance of new Applications and the
issuance of new Certificates under a Group Contract by giving 30 days prior
written notice to the Owner. This will not affect rights or benefits with
respect to any Participant Accounts established under such Group Contract prior
to the effective date of such limitation or discontinuance.

RESERVATION OF RIGHTS

      We reserve the right, to the extent permitted by law, to: (1) combine any
2 or more variable accounts; (2) add or delete Funds or other investment
companies and corresponding Sub-Accounts; (3) add or remove Guarantee Periods
available at any time for election by a Participant; and (4) restrict or
eliminate any of the voting rights of Participants (or Owners) or other persons
who have voting rights as to the Variable Account. Where required by law, we
will obtain approval of changes from Participants or any appropriate regulatory
authority. In the event of any change pursuant to this provision, we may make
appropriate endorsement to the Contract to reflect the change.

RIGHT TO RETURN

      If you are not satisfied with your Contract, you may return it by mailing
or delivering it to us at our Annuity Mailing Address as shown on the cover of
this Prospectus within 10 days after it was delivered to you. When we receive
the returned Contract, it will be cancelled and we will refund to you your
Account Value at the end of the Valuation Period during which we received it.
However, if applicable state law requires we will return the full amount of any
Purchase Payment(s) we received. State law may also require us to give you a
longer "free look" period or allow you to return the Contract to your sales
representative.

      If you are establishing an Individual Retirement Account ("IRA"), the
Internal Revenue Code requires that we give you a disclosure statement
containing certain information about the Contract and applicable legal
requirements. We must give you this statement on or before the date the IRA is
established. If we give you the disclosure statement before the seventh day
preceding the date the IRA is established, you will not have any right of
revocation under the Code. If we give you the disclosure

                                       34
<PAGE>
statement at a later date, then you may give us a notice of revocation at any
time within 7 days after your Contract Date. Upon such revocation, we will
refund your Purchase Payment(s). This right of revocation with respect to an IRA
is in addition to the return privilege set forth in the preceding paragraph. We
allow a Participant establishing an IRA a "ten day free-look," notwithstanding
the provisions of the Internal Revenue Code.

                               TAX CONSIDERATIONS

U.S. FEDERAL TAX CONSIDERATIONS

      The following discussion applies only to those Contracts issued in the
United States. For a discussion of tax considerations effecting Contracts issued
in Puerto Rico, see "Puerto Rico Tax Considerations," below.

      DEDUCTIBILITY OF PURCHASE PAYMENTS

      For federal income tax purposes, Purchase Payments made under
Non-Qualified Contracts are not deductible.

      PRE-DISTRIBUTION TAXATION OF CONTRACTS

      Generally, an increase in the value of a Contract will not give rise to
tax, prior to distribution.


      However, corporate (or other non-natural person) Owners of, and
Participants under, a Non-Qualified Contract incur current tax, regardless of
distribution, on Contract value increases. Such current taxation does not apply
to (i) any immediate annuity, which the Internal Revenue Code (the "Code")
defines as a single premium contract with an annuity commencement date within
one year of the date of purchase, or (ii) any Contract that the non-natural
person holds as agent for a natural person (such as where a bank or other entity
holds a Contract as trustee under a trust agreement).


      You should note that qualified retirement investments automatically
provide tax deferral regardless of whether the underlying contract is an
annuity.

      DISTRIBUTIONS AND WITHDRAWALS FROM NON-QUALIFIED CONTRACTS

      The Account Value will include an amount attributable to Purchase
Payments, the return of which is not taxable, and an amount attributable to
investment earnings, the return of which is taxable at ordinary income rates.
The relative portions of a distribution that derive from nontaxable Purchase
Payments and taxable investment earnings depend upon the timing of the
distribution.

      If you withdraw less than your entire Account Value under a Non-Qualified
Contract before the Annuity Commencement Date, you must treat the distribution
first as a return of investment earnings. You may treat only withdrawals in
excess of the amount of the Account Value attributable to investment earnings as
a return of Purchase Payments. Account Value amounts assigned or pledged as
collateral for a loan will be treated as if withdrawn from the Contract.

      If a Payee receives annuity payments under a Non-Qualified Contract after
the Annuity Commencement Date, however, the Payee treats a portion of each
payment as a nontaxable return of Purchase Payments. In general, the nontaxable
portion of such a payment bears the same ratio to the total payment as the
Purchase Payments bear to the Payee's expected return under the Contract. The
remainder of the payment constitutes a taxable return of investment earnings.
Once the Payee has received nontaxable payments in an amount equal to total
Purchase Payments, all future distributions constitute fully taxable ordinary
income. If the Annuitant dies before the Payee recovers the full amount of
Purchase Payments, the Payee may deduct an amount equal to unrecovered Purchase
Payments.

      Upon the transfer of a Non-Qualified Contract by gift (other than to the
Participant's spouse), the Participant must treat an amount equal to the Account
Value minus the total amount paid for the Contract as income.

      A penalty tax of 10% may apply to taxable cash withdrawals and lump-sum
payments from Non-Qualified Contracts. This penalty will not apply in certain
circumstances, such as distributions pursuant

                                       35
<PAGE>
to the death of the Participant or distributions under an immediate annuity (as
defined above), or after age 59 1/2.

      DISTRIBUTIONS AND WITHDRAWALS FROM QUALIFIED CONTRACTS

      Generally, distributions from a Qualified Contract will constitute fully
taxable ordinary income. Also, a 10% penalty tax will, except in certain
circumstances, apply to distributions prior to age 59 1/2.

      Distributions from a Qualified Contract are not subject to current
taxation or a 10% penalty, however, if:

      -  the distribution is not a hardship distribution or part of a series of
         payments for life or for a specified period of 10 years or more (an
         "eligible rollover distribution"), and

      -  the Participant or Payee rolls over the distribution (with or without
         actually receiving the distribution) into a qualified retirement plan
         eligible to receive the rollover.

      Only you or your spouse may elect to roll over a distribution to an
eligible retirement plan.

      WITHHOLDING

      In the case of an eligible rollover distribution (as defined above) from a
Qualified Contract (other than from a Contract issued for use with an individual
retirement account), we (or the plan administrator) must withhold and remit to
the U.S. Government 20% of the distribution, unless the Participant or Payee
elects to make a direct rollover of the distribution to another qualified
retirement plan that is eligible to receive the rollover; however, only you or
your spouse may elect a direct rollover. In the case of a distribution from
(i) a Non-Qualified Contract, (ii) a Qualified Contract issued for use with an
individual retirement account, or (iii) a Qualified Contract where the
distribution is not an eligible rollover distribution, we will withhold and
remit to the U.S. Government a part of the taxable portion of each distribution
unless, prior to the distribution, the Participant or Payee provides us his or
her taxpayer identification number and instructs us (in the manner prescribed)
not to withhold. The Participant or Payee may credit against his or her federal
income tax liability for the year of distribution any amounts that we (or the
plan administrator) withhold.

      INVESTMENT DIVERSIFICATION AND CONTROL

      The Treasury Department has issued regulations that prescribe investment
diversification requirements for mutual fund series underlying nonqualified
variable contracts. Contracts must comply with these regulations to qualify as
annuities for federal income tax purposes. Contracts that do not meet the
guidelines are subject to current taxation on annual increases in value. We
believe that each Fund complies with these regulations. The preamble to the
regulations states that the Internal Revenue Service may promulgate guidelines
under which an owner's excessive control over investments underlying the
contract will preclude the contract from qualifying as an annuity for federal
tax purposes. We cannot predict whether such guidelines, if in fact promulgated,
will be retroactive. We reserve the right to modify the Contract and/or the
Variable Account to the extent necessary to comply with any such guidelines.

      TAX TREATMENT OF THE COMPANY AND THE VARIABLE ACCOUNT

      As a life insurance company under the Code, we will record and report
operations of the Variable Account separately from other operations. The
Variable Account will not, however, constitute a regulated investment company or
any other type of taxable entity distinct from our other operations. We will not
incur tax on the income of the Variable Account (consisting primarily of
interest, dividends, and net capital gains) if we use this income to increase
reserves under Contracts participating in the Variable Account.

      QUALIFIED RETIREMENT PLANS

      You may use Qualified Contracts with several types of qualified retirement
plans. Because tax consequences will vary with the type of qualified retirement
plan and the plan's specific terms and conditions, we provide below only brief,
general descriptions of the consequences that follow from using Qualified
Contracts in connection with various types of qualified retirement plans. We
stress that

                                       36
<PAGE>
the rights of any person to any benefits under these plans may be subject to the
terms and conditions of the plans themselves, regardless of the terms of the
Qualified Contracts that you are using. These terms and conditions may include
restrictions on, among other things, ownership, transferability, assignability,
contributions and distributions.

      PENSION AND PROFIT-SHARING PLANS

      Sections 401(a), 401(k) and 403(a) of the Code permit business employers
and certain associations to establish various types of retirement plans for
employees. The Tax Equity and Fiscal Responsibility Act of 1982 eliminated most
differences between qualified retirement plans of corporations and those of
self-employed individuals. Self-employed persons may therefore use Qualified
Contracts as a funding vehicle for their retirement plans, as a general rule.

      TAX-SHELTERED ANNUITIES

      Section 403(b) of the Code permits public school employees and employees
of certain types of charitable, educational and scientific organizations
specified in Section 501(c)(3) of the Code to purchase annuity contracts and,
subject to certain limitations, exclude the amount of purchase payments from
gross income for tax purposes. The Code imposes restrictions on cash withdrawals
from Section 403(b) annuities.


      If the Contracts are to receive tax-deferred treatment, cash withdrawals
of amounts attributable to salary reduction contributions (other than
withdrawals of accumulation account value as of December 31, 1988) may be made
only when the Participant 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 (i) any post-1988 salary reduction
contributions, (ii) any growth or interest on post-1988 salary reduction
contributions, and (iii) any growth or interest on pre-1989 salary reduction
contributions that occurs on or after January 1, 1989. It is permissible,
however, to withdraw post-1988 salary reduction contributions in cases of
financial hardship. While the Internal Revenue Service has not issued specific
rules defining financial hardship, we expect that to qualify for a hardship
distribution, the Participant 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 Contracts. Under certain circumstances the 10% tax penalty will not
apply if the withdrawal is for medical expenses.


      Under the terms of a particular Section 403(b) plan, the Participant may
be entitled to transfer all or a portion of the Account Value to one or more
alternative funding options. Participants should consult the documents governing
their plan and the person who administers the plan for information as to such
investment alternatives.

      INDIVIDUAL RETIREMENT ACCOUNTS

      Sections 219 and 408 of the Code permit eligible individuals to contribute
to an individual retirement program, including Simplified Employee Pension
Plans, Employer/Association of Employees Established Individual Retirement
Account Trusts, and Simple Retirement Accounts. Such IRAs are subject to
limitations on contribution levels, the persons who may be eligible, and on the
time when distributions may commence. In addition, certain distributions from
some other types of retirement plans may be placed in an IRA on a tax-deferred
basis. If we sell Contracts for use with IRAs, the Internal Revenue Service or
other agency may impose supplementary information requirements. We will provide
purchasers of the Contracts for such purposes with any necessary information.
You will have the right to revoke the Contract under certain circumstances, as
described in the section of this Prospectus entitled "Right to Return."

      ROTH IRAS

      Section 408A of the Code permits an individual to contribute to an
individual retirement program called a Roth IRA. Unlike contributions to a
traditional IRA under Section 408 of the Code,

                                       37
<PAGE>
contributions to a Roth IRA are not tax-deductible. Provided certain conditions
are satisfied, distributions are generally tax-free. Like traditional IRAs, Roth
IRAs are subject to limitations on contribution amounts and the timing of
distributions. If an individual converts a traditional IRA into a Roth IRA the
full amount of the IRA is included in taxable income. The Internal Revenue
Service and other agencies may impose special information requirements with
respect to Roth IRAs. If and when we make Contracts available for use with Roth
IRAs, we will provide any necessary information.

PUERTO RICO TAX CONSIDERATIONS


      The Contract offered by this Prospectus is considered an annuity contract
under Section 1022 of the Puerto Rico Internal Revenue Code of 1994, as amended
(the "1994 Code"). Under the current provisions of the 1994 Code, no income tax
is payable on increases in value of accumulation shares of annuity units
credited to a variable annuity contract until payments are made to the annuitant
or other payee under such contract.


      If any annuity distributions are made under an annuity contract, the
annuitant or other payee will be required to include as gross income the portion
of each payment equal to 3% of the aggregate premiums or other consideration
paid for the annuity. The amount, if any, in excess of the included amount is
excluded from gross income. After an amount equal to the aggregate amount
excluded from gross income has been received, all of the annuity payments are
considered to be taxable income.

      In the event payment under a Contract is made in a lump sum, the amount of
the payment would be included in the gross income of the Annuitant or other
Payee to the extent of the Annuitant's aggregate premiums or other consideration
paid.


      The provisions of the 1994 Code with respect to qualified retirement plans
described in this Prospectus vary significantly from those under the Internal
Revenue Code. Although we currently offer the Contract in Puerto Rico in
connection with qualified retirement plans, the text of this Prospectus under
the heading "U.S. Federal Tax Considerations" dealing with such qualified
retirement plans is inapplicable to Puerto Rico and should be disregarded.


      For further information regarding the income tax consequences of owning a
Contract, you should consult a qualified tax adviser.

                        ADMINISTRATION OF THE CONTRACTS

      We perform certain administrative functions relating to the Contracts,
Participant Accounts, and the Variable Account. These functions include, but are
not limited to, maintaining the books and records of the Variable Account and
the Sub-Accounts; maintaining records of the name, address, taxpayer
identification number, Contract number, Participant Account number and type, the
status of each Participant Account and other pertinent information necessary to
the administration and operation of the Contracts; processing Applications,
Purchase Payments, transfers and full and partial withdrawals; issuing Contracts
and Certificates; administering annuity payments; furnishing accounting and
valuation services; reconciling and depositing cash receipts; providing
confirmations; providing toll-free customer service lines; and furnishing
telephonic transfer services.

                         DISTRIBUTION OF THE CONTRACTS

      We offer the Contracts on a continuous basis. The Contracts are sold by
licensed insurance agents in those states where the Contracts may be lawfully
sold. 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. and who have entered into
distribution agreements with the Company and the general distributor, Clarendon
Insurance Agency, Inc. ("Clarendon"), One Sun Life Executive Park, Wellesley
Hills, Massachusetts 02481. Clarendon, a wholly-owned subsidiary of the Company,
is registered with the SEC under the Securities Exchange Act of 1934 as a
broker-dealer and is a member of the National Association of Securities Dealers,
Inc.

                                       38
<PAGE>
      Commissions and other distribution compensation will be paid by the
Company to the selling agents and will not be more than 7.46% of Purchase
Payments. In addition, after the first Account Year, broker-dealers who have
entered into distribution agreements with the Company may receive an annual
renewal commission of no more than 1.00% of Participant Account Value. In
addition to commissions, the Company may, from time to time, pay or allow
additional promotional incentives, in the form of cash or other compensation. In
some instances, such other incentives may be offered only to certain
broker-dealers that sell or are expected to sell during specified time periods
certain minimum amounts of the Contracts or Certificates or other contracts
offered by the Company. Commissions will not be paid with respect to Accounts
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, or of
immediate family members of such employees or persons. In addition, commissions
may be waived or reduced in connection with certain transactions described in
this Prospectus under the heading "Waivers; Reduced Charges; Credits; Bonus
Guaranteed Interest Rates." During 1999, approximately $79,103, respectively,
was paid to Clarendon in connection with distribution of the Contracts.

                            PERFORMANCE INFORMATION

      From time to time the Variable Account may publish reports to
shareholders, sales literature and advertisements containing performance
information relating to the variable option. This information may include
"Average Annual Total Return," "Cumulative Growth Rate" and "Cumulative Compound
Growth Rate." We may also advertise "yield" and "effective yield" for some
variable options.

      Average Annual Total Return measures the net income of the variable option
and any realized or unrealized gains or losses of the Funds in which it invests,
over the period stated. Average Annual Total Return figures are annualized and
represent the average annual percentage change in the value of an investment in
a variable option over that period. Standardized Average Annual Total Return
information covers the period after we began offering the Futurity products or,
if shorter, the life of the Fund. Non-standardized Average Annual Total Return
covers the life of each Fund, which may predate the Futurity products.
Cumulative Growth Rate represents the cumulative change in the value of an
investment in the Sub-Account for the period stated, and is arrived at by
calculating the change in the Accumulation Unit Value of a Sub-Account between
the first and last day of the period being measured. The difference is expressed
as a percentage of the Accumulation Unit Value at the beginning of the base
period. "Compound Growth Rate" is an annualized measure, calculated by applying
a formula that determines the level of return which, if earned over the entire
period, would produce the cumulative return.

      Average Annual Total Return figures assume an initial Purchase Payment of
$1,000 and reflect all applicable withdrawal and Contract charges. The
Cumulative Growth Rate and Compound Growth Rate figures that we advertise do not
reflect withdrawal charges or the annual Account Fee, although they reflect all
recurring charges. Results calculated without withdrawal and/or certain Contract
charges will be higher. We may also use other types of rates of return that do
not reflect withdrawal and Contract charges.

      The performance figures used by the Variable Account are based on the
actual historical performance of the Funds for the specified periods, and the
figures are not intended to indicate future performance. For periods before the
date the Contracts became available, we calculate the performance information
for the Sub-Account on a hypothetical basis. To do this, we reflect deductions
of the current Contract fees and charges from the historical performance of the
corresponding Fund.


      Yield is a measure of the net dividend and interest income earned over a
specific one month or 30-day period (7-day period for the MFS/Sun Life Money
Market Sub-Account), expressed as a percentage of the value of the Sub-Account's
Accumulation Units. Yield is an annualized figure, which means that we assume
that the Sub-Account generates the same level of net income over a one-year
period and compound that income on a semi-annual basis. We calculate the
effective yield for the MFS/Sun Life Money Market Sub-Account similarly, but
include the increase due to assumed compounding. The MFS/Sun Life Money Market
Sub-Account's effective yield will be slightly higher than its yield as a result
of its compounding effect.


                                       39
<PAGE>
      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
information on performance and our computations is set forth in the Statement of
Additional Information.

      The Company may also advertise the ratings and other information assigned
to it by independent industry ratings organizations. Some of these organizations
are A.M. Best, Moody's Investor's Service, Standard and Poor's Insurance Rating
Services, and Duff and Phelps. Each year A.M. Best reviews the financial status
of thousands of insurers, culminating in the assignment of Best's rating. These
ratings reflect A.M. Best's current opinion of the relevant financial strength
and operating performance of an insurance company in comparison to the norms of
the life/health industry. Best's ratings range from A++ to F. Standard and
Poor's and Duff and Phelps' ratings measure the ability of an insurance company
to meet its obligations under insurance policies it issues. These two ratings do
not measure the insurance company's ability to meet non-policy obligations.
Ratings in general do not relate to the performance of the Sub-Accounts.


      We may also advertise endorsements from organizations, individuals or
other parties that recommend the Company or the Contracts. We may occasionally
include in advertisements (1) comparisons of currently taxable and tax-deferred
investment programs, based on selected tax brackets; or (2) discussions of
alternative investment vehicles and general economic conditions.

MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS

CAUTIONARY STATEMENT

      This Prospectus includes forward-looking statements by the Company under
the Private Securities Litigation Reform Act of 1995. These statements are not
matters of historical fact; they relate to such topics as future product sales,
volume growth, market share, market risk and financial goals. It is important to
understand that these forward-looking statements are subject to certain risks
and uncertainties that could cause actual results to differ materially from
those that the statements anticipate. These risks and uncertainties may concern,
among other things:

    - Heightened competition, particularly in terms of price, product features,
      and distribution capability, which could constrain the Company's growth
      and profitability.

    - Changes in interest rates and market conditions.

    - Regulatory and legislative developments.

    - Developments in consumer preferences and behavior patterns.

RESULTS OF OPERATIONS

      1999 COMPARED TO 1998:

      NET INCOME

      Net income decreased by $35.0 million to $90.4 million in 1999, reflecting
a decrease of $54.7 million in income from operations and an increase of
$19.7 million in net realized capital gains. (In the following discussion,
"income from operations" refers to the statutory statements of operations line
item, "net gain from operations after dividends to policyholders and federal
income tax and before realized capital gains.")

      Income from operations decreased from $125.0 million in 1998 to
$70.3 million in 1999, mainly as a result of the following factors:

    - A $32.3 million increase, to $63.7 million in 1999, in the income from
      operations from the Company's Wealth Management segment. (See "1999
      Compared to 1998 -- Wealth Management Segment," below.)

    - The effect of terminating certain reinsurance agreements with the
      Company's ultimate parent in 1998. The termination of these agreements was
      the predominant factor in the $94.2 million decrease in income from
      operations for the Company's Protection segment. (See "1999 Compared to
      1998 -- Protection Segment," below.)

    - An increase of $7.2 million in income from operations from the Corporate
      segment, mainly reflecting dividends from a subsidiary. (See "1999
      Compared to 1998 -- Corporate Segment," below.)

      INCOME FROM OPERATIONS BY SEGMENT

      The Company's income from operations reflects the operations of its 3
business segments: the Wealth Management segment, the Protection segment and the
Corporate segment.

      WEALTH MANAGEMENT SEGMENT

      The Wealth Management segment focuses on the savings and retirement needs
of individuals preparing for retirement or who have already retired. It
primarily markets to upscale consumers in the U.S., selling individual and group
fixed and variable annuities. Its major product lines, "Regatta" and "Futurity,"
are combination fixed/variable annuities. In these combination annuities,
contract holders have the choice of allocating payments either to a fixed
account, which provides a guaranteed rate of return, or to variable accounts.
Withdrawals from the fixed account are subject to market value adjustment. In
the variable accounts, the contract holder can choose from a range of investment
options and styles. The return depends upon investment performance of the
options selected. Investment funds available under Regatta products are managed
by Massachusetts Financial Services Company ("MFS"), an affiliate of the
Company. Investment funds available under Futurity products are managed by
several investment managers, including MFS and Sun Capital Advisers, Inc., a
subsidiary of the Company.

      The Company distributes its annuity products through a variety of
channels. For the Regatta products, about half are sold through securities
brokers; a further one-fourth through financial institutions, and the remainder
through insurance agents and financial planners. The Futurity products,
introduced in February 1998, are primarily distributed through a dedicated
wholesaler network, including Sun Life of Canada (U.S.) Distributors, Inc., a
subsidiary of the Company.

      Although new pension products are not currently sold, there has been a
substantial block of group retirement business in-force, including guaranteed
investment contracts ("GICs"), pension plans and group annuities. A significant
portion of these pension contracts are non-surrenderable, with the result that
the Company's liquidity exposure is limited. GICs were marketed directly in the
U.S. through independent managers. In 1997, the Company decided to no longer
market group pension and GIC products.

      Following are the major factors affecting this segment's results in 1999
as compared to 1998.

    - Deposit-type funds, which primarily comprised annuity deposits, increased
     by $457.7 million, or 21%, to $2,598.3 million in 1999. Fixed annuity
     account deposits were higher by approximately $625 million in 1999, which
     management believes is mainly a result of the success of the Company's
     introduction, during the fourth quarter of 1998, of a higher Dollar Cost
     Averaging ("DCA") rate and a new 6-month DCA program. Under these programs,
     which were redesigned in late 1996, deposits are made into the fixed
     portion of the annuity contract and receive a bonus rate of interest for
     the policy year. During the year, the fixed deposit is systematically
     transferred to the variable portion of the contract in equal periodic
     installments. While fixed annuity account deposits increased, deposits
     directly into variable accounts declined by approximately 13% in 1999. The
     Company believes this decline was a consequence of the heightened interest
     in the DCA programs in 1999.

    - Sales of the Futurity line of products, introduced in February 1998,
     represented approximately 9% of total annuity deposits in 1999. The Company
     expects that sales of the Futurity products

                                       43
<PAGE>
     will continue to increase in the future, based on management's beliefs that
     market demand is growing for multi-manager variable annuity products, such
     as Futurity; that the productivity of Futurity's wholesale distribution
     network, established in 1998, will continue to grow; and that the
     marketplace will respond favorably to introductions of new Futurity
     products and product enhancements.

    - Fee income increased as a result of higher variable annuity account
     balances. Fee income was higher by approximately $32 million in 1999. The
     factors driving this growth in account balances have been market
     appreciation and net deposit activity. This growth has generated
     corresponding increases in fee income, since fees are determined based on
     the average assets held in these accounts. Other income increased by
     approximately $5 million in 1999, mainly reflecting a reinsurance agreement
     entered into in July 1999 with an unrelated company, which provides
     reinsurance on certain fixed group annuity contracts. The net effect of
     this agreement was to increase income from operations by approximately
     $3.4 million.

    - The net year-over-year change in aggregate reserves on policies and
     contracts for the Wealth Management segment had the effect of increasing
     income from operations for this segment. This change reflected lower
     reserves related to minimum guaranteed death benefit product features as
     well as a variety of other factors.

    - There has been a shift in demand to variable account products from general
     account products. As a consequence, there has been a decline in average
     general account invested assets and, in turn, net investment income has
     declined. Net investment income reflects only income earned on invested
     assets of the general account. In 1999, net investment income for the
     Wealth Management segment decreased by $44.0 million, to $114.0 million.
     This decline in average general account assets primarily reflects the
     Company's decision in 1997 to no longer market group pension and GIC
     products and as a consequence, a declining block of in-force business as
     GICs mature and are surrendered.

    - Policyholder benefits (the major elements of which are surrenders and
     withdrawals, changes in the liability for premium and other deposit funds,
     and related separate account transfers) were higher by approximately $430
     million in 1999, mainly as a result of higher variable annuity surrenders.
     The increase in variable annuity surrenders was primarily related to a
     block of separate account contracts that had been issued seven or more
     years previously and for which the surrender charge periods had expired.
     The Company expects that as the separate account block of business
     continues to grow and as an increasing number of accounts are no longer
     subject to surrender charges, surrenders will tend to increase. The Company
     is implementing a conservation program with the aim of improving asset
     retention.

    - Operational expenses, which include general insurance expenses and
     insurance taxes, licenses and fees, excluding federal income taxes,
     increased by $5.4 million, or 9%, in 1999. This increase reflected costs
     associated with operations and technology improvements to support the
     growth of the Company's in-force business. Commissions of $153.6 million
     were higher by $17.7 million in 1999, mainly as a result of higher sales.

      PROTECTION SEGMENT

      The Protection Segment comprises two main elements, internal reinsurance
and variable life products.

      INTERNAL REINSURANCE

      In recent years, the Company has had various reinsurance agreements with
Sun Life (Canada). In some of these arrangements, Sun Life (Canada) has
reinsured the mortality risks of individual life policies sold in prior years by
the Company. These agreements, in the aggregate, had an immaterial effect on net
income in the years 1998 and 1999. Under another reinsurance agreement, which
became effective January 1, 1991 and terminated October 1, 1998, the Company
reinsured certain individual life insurance contracts issued by Sun Life
(Canada). This agreement had the effect of increasing income

                                       44
<PAGE>
from operations by $24.6 million in 1998. In addition, the effect of terminating
this agreement was to further increase 1998 net income by $65.7 million as the
termination payment was less than the reserves held under the agreement. Because
this agreement terminated in 1998, it had no effect on income from operations in
1999.

      VARIABLE LIFE PRODUCTS

      The Company's primary individual variable life insurance product is its
variable universal life product marketed to the company-owned life insurance
("COLI") market. This product was introduced in late 1997. The Company's
management expects that the Company's variable life business will grow and
become more significant in the future. In September 1999, the Company introduced
a new variable universal life product as part of the Futurity product portfolio.
Costs related to developing this product were primarily responsible for the
decrease of approximately $4 million in income from operations for this portion
of the Protection segment.

      CORPORATE SEGMENT

      The Corporate segment includes the capital of the Company, its investments
in subsidiaries and items not otherwise attributable to either the Wealth
Management segment or the Protection segment.

      In 1999, income from operations for this segment increased by
$7.2 million to $11.7 million. This increase reflected higher net investment
income, mainly from dividends of $19.3 million received during the 4th quarter
from a subsidiary, New London Trust, F.S.B. Partially offsetting this change in
net investment income were higher operational expenses and higher federal income
taxes attributable to this segment.

      1998 COMPARED TO 1997:

      NET INCOME

      Net income decreased by $3.8 million to $125.4 million in 1998, reflecting
an increase of $22.5 million in income from operations and a decrease of
$26.3 million in net realized capital gains.

      Income from operations increased from $102.5 million in 1997 to
$125.0 million in 1998, mainly as a result of the following factors:

    - A $16.7 million increase, to $31.4 million in 1998, in the income from
     operations from the Company's Wealth Management segment. (See "1998
     Compared to 1997 -- Wealth Management Segment," below.)

    - The effect of terminating certain reinsurance agreements with Sun Life
     (Canada). The termination of these agreements was the predominant factor in
     the $71.1 million increase in income from operations for the Company's
     Protection segment.

    - The effects of the Company's December 1997 reorganization (described in
     "Corporate Segment," below), as a result of which MFS is no longer a
     subsidiary of the Company. As a result of this reorganization, dividends
     from subsidiaries were lower in 1998 than in 1997 and certain subsidiary
     tax benefits were no longer available to the Company. Also affecting income
     from operations for the Corporate segment in 1998 was that income earned on
     the proceeds of a December 1997 issuance of a $250 million surplus note was
     lower than the related interest expense.

                                       45
<PAGE>
      Net realized capital gains decreased from $26.7 million in 1997 to
$0.4 million in 1998. This decrease was also due to the Company's December 1997
reorganization which resulted in a realized capital gain of $21.2 million in
1997.

      INCOME FROM OPERATIONS BY SEGMENT

      WEALTH MANAGEMENT SEGMENT

      Following are the major factors affecting the Wealth Management segment's
results in 1998 as compared to 1997:

    - Annuity deposits declined by about $27 million, or 1%, to $2.2 billion in
     1998. Fixed annuity account deposits were lower by approximately 7% in
     1998, while deposits into variable annuity accounts increased in total and
     as a proportion of total annuity deposits. These trends reflected market
     conditions and competitive factors.

    - Deposits into the DCA programs, a feature of the Company's combination
     fixed/variable annuity products, were a significant element of account
     deposits. Under these programs, which were redesigned in late 1996,
     deposits are made into the fixed portion of the annuity contract and
     receive a bonus rate of interest for the policy year. During the year, the
     fixed deposit is systematically transferred to the variable portion of the
     contract in equal periodic installments. DCA deposits overall were flat in
     1998 compared to 1997. This pattern resulted, in part, from heightened
     competition, as other companies introduced similar DCA programs within in
     1998. During the fourth quarter of 1998, the Company introduced a higher
     DCA rate and a new six-month DCA program. DCA deposits for that quarter
     were higher, compared to the preceding 1998 quarters.

    - An increase in variable account deposits in 1998 reflected both the
     continuing strong growth in equity markets generally and the continuing
     strong performance of the investment funds underlying the Company's
     variable annuity products. The continuing strong equity markets, low
     interest rate environment, and demographic trends, among other factors,
     increased the demand and market for wealth accumulation products in the
     U.S., particularly for variable annuities. These factors contributed to the
     growth in the Company's variable account deposits in 1998, despite
     heightened competition.

     The Company introduced its Futurity line of products in February 1998.
     Related deposits represented about 6% of the total for the Wealth
     Management segment in 1998.

    - Fee income increased as a result of higher variable annuity account
      balances. The main factors driving this growth in account balances were
      market appreciation and net deposit activity. This growth generated
      corresponding increases in fee income, since fees are determined based on
      the average assets held in these accounts. Fee income increased by
      approximately $43 million, or 39%, in 1998.

    - Because there was a shift to variable accounts from the general account,
      net investment income declined. Net investment income reflects only income
      earned on invested assets of the general account. In 1998, net investment
      income for the Wealth Management segment decreased by about $40 million,
      or 20%, compared to 1997, mainly as a result of the decline in average
      invested assets in the Company's general account. This decline in average
      general account assets mainly reflected the shift in deposits in recent
      years from the fixed account to variable accounts. It also reflected the
      Company's decision in 1997 to no longer market group pension and GICs.

    - Policyholder benefits were lower, mainly reflecting lower surrender
      activity compared to 1997. During 1997 and into the first half of 1998,
      surrender and withdrawal activity had been high. This activity primarily
      related to a block of separate account contracts that had been issued 7 or
      more years previously and for which the surrender charge periods had
      expired. While variable account surrenders continued to rise, general
      account surrenders declined in 1998. As a result of this pattern of
      activity, policyholder benefits (of which surrenders and withdrawals, the
      related

                                       46
<PAGE>
      changes in the liability for premium and other deposit funds, and related
      separate account transfers are the major elements) increased in 1997 and
      were lower in 1998.

    - As a result of investments in technology and infrastructure to enhance
      annuity operations, operational expenses increased by approximately $12
      million, or 25%, in 1998 compared to 1997. These increases reflected 3
      main factors:

       - Higher volumes of annuity business, requiring greater administrative
         support.

       - Improvements to the computer systems and technology that support the
         annuity business. These improvements involved information systems
         supporting the growth of the Company's in-force business, particularly
         its combination fixed/variable annuities.

       - Costs associated with the product design and implementation of the new
         Futurity multi-manager annuity product and the development of a new
         product within the Regatta product line.

      PROTECTION SEGMENT

      The reinsurance arrangements in which Sun Life (Canada) has reinsured the
mortality risks of individual life policies sold in prior years by the Company
had an immaterial effect, in the aggregate, on net income in 1997 and 1998.
Under another agreement, which became effective January 1, 1991 and terminated
October 1, 1998, the Company reinsured certain individual life insurance
contracts issued by Sun Life (Canada). This agreement had the effect of
increasing income from operations by $37.1 million in 1997. Income from
operations decreased to $24.6 million in 1998, because the agreement was in
place only through the first 9 months of 1998. In addition, the effect of
terminating this agreement was to further increase 1998 net income by $65.7
million. This termination-related increase in 1998 represented a reasonable
approximation of the value of the stream of future earnings that the agreement
would have generated had it remained in effect.

      The Company's primary individual variable life insurance product is its
variable universal life product marketed to the company-owned life insurance
("COLI") market. This product was introduced in late 1997.

      CORPORATE SEGMENT

      In 1998, income from operations decreased by $65.3 million to
$4.5 million for the Corporate segment. This decrease reflected 2 main factors:

    - Dividends from subsidiaries were lower than in 1997 by $37.5 million. This
      decrease mainly resulted from a December 1997 reorganization, in which the
      Company transferred its ownership of MFS to its parent company, Sun Life
      of Canada (U.S.) Holdings, Inc. ("Sun Life (U.S.) Holdings.") As a result
      of this reorganization, the Company received no dividends from MFS in
      1998. By comparison, it received $33.1 million of MFS dividends in 1997.

    - Net investment income, other than dividends from subsidiaries, decreased
      by $5.9 million in 1998 over 1997, reflecting the effect of the Company's
      December 1997 issuance of a $250 million surplus note to Sun Life (U.S.)
      Holdings. Interest expense exceeded investment earnings on the related
      funds.

FINANCIAL CONDITION AND LIQUIDITY

      ASSETS

      The Company's total assets comprise those held in its general account and
those held in its separate accounts. General account assets support general
account liabilities. Separate accounts and their assets are of 2 main types:

    - Those assets held in a "fixed" separate account, which the Company
      established for amounts that contract holders allocate to the fixed
      portion of their combination fixed/variable deferred annuity contracts.
      Fixed separate account assets are available to fund general account
      liabilities

                                       47
<PAGE>
      and general account assets are available to fund the liabilities of this
      fixed separate account. The Company manages the assets of this fixed
      separate account according to general account investment policy
      guidelines.

    - Those assets held in a number of registered and non-registered "variable"
      separate accounts as investment vehicles for the Company's variable life
      and annuity contracts. Policyholders may choose from among various
      investment options offered under these contracts according to their
      individual needs and preferences. Policyholders assume the investment
      risks associated with these choices. General account and fixed separate
      account assets are not available to fund the liabilities of these variable
      accounts.

      The following table summarizes significant changes in asset balances
during 1999, 1998 and 1997. The changes are discussed below.

</TABLE>


      General account and fixed separate account assets, taken together,
decreased by 13.2% in 1999; but variable separate account assets increased by
31.6%. In 1998, the combined general account and fixed separate account
decreased by 25.2%, while variable separate account assets increased by 29.9%.
This growth in variable accounts relative to the general and fixed accounts
reflects 2 main factors: (1) appreciation of the funds held in the variable
separate accounts has exceeded that of the funds held in the general and fixed
separate accounts; and (2) annuity deposits and exchanges into variable accounts
have increased, while annuity deposits into fixed accounts have slowed. The
Company believes this pattern has reflected a shift in the preferences of
policyholders, which is largely attributable to the strong performance of equity
markets in general and of the Company's variable account funds in particular.

      The assets of the general account are available to support general account
liabilities. For management purposes, it is the Company's practice to segment
its general account to facilitate the matching of assets and liabilities.
General account assets primarily comprise cash and invested assets, which
represented essentially all of general account assets at year-end 1999. Major
types of invested asset holdings included bonds, mortgages, real estate and
common stock. The Company's bond holdings comprised 51.5% of the Company's
portfolio at year-end 1999. Bonds included both public and private issues. It is
the Company's policy to acquire only investment-grade securities. As a result,
the overall quality of the bond portfolio is high. At year-end 1999, only 0.5%
were rated below-investment-grade; i.e., they had National Association of
Insurance Commissioners ("NAIC") ratings lower than "1" or "2." The Company's
mortgage holdings amounted to $528.9 million at year-end 1999, representing
22.3% of the total portfolio. All mortgage holdings at year-end 1999 were in
good standing. The Company believes that the high quality of its mortgage
portfolio is largely attributable to its stringent underwriting standards. At
year-end 1999, investment real estate amounted to $79.2 million, representing
about 3.3% of the total portfolio. The Company invests in real estate to enhance
yields and, because of the long-term nature of these investments, the Company
uses them for purposes of matching with products having long-term liability
durations. Common stock holdings amounted to $75.3 million, representing about
3.2% of the portfolio. These holdings comprised the Company's ownership shares
in subsidiaries.

                                       48
<PAGE>
      LIABILITIES

      As with assets, the proportion of variable separate account liabilities to
total liabilities has been increasing. Most of the Company's liabilities
comprise reserves for life insurance and for annuity contracts and deposit
funds. The Company expects the declining trend in general account liabilities to
continue, because it believes that net maturities will continue to exceed sales
for the fixed contracts associated with these liabilities. This trend stems
mainly from the Company's 1997 decision to discontinue selling group pension and
GIC contracts and to focus its marketing efforts on its combination
fixed/variable annuity products.

CAPITAL MARKETS RISK MANAGEMENT

      See "Quantitative and Qualitative Disclosures About Market Risk," below,
for a discussion of the Company's capital markets risk management.

CAPITAL RESOURCES

      CAPITAL ADEQUACY

      The National Association of Insurance Commissioners ("NAIC") adopted
regulations at the end of 1993 that established minimum capitalization
requirements for insurance companies, based on risk-based capital ("RBC")
formulas. These requirements are intended to identify undercapitalized
companies, so that specific regulatory actions can be taken on a timely basis.
The RBC formula for life insurance companies calculates capital requirements
related to asset, insurance, interest rate, and business risks. According to the
RBC calculation, the Company's capital was well in excess of its required
capital at year-end 1999.

      LIQUIDITY

      The Company's liquidity requirements are generally met by funds from
operations. The Company's main uses of funds are to pay out death benefits and
other maturing insurance and annuity contract obligations; to make pay-outs on
contract terminations; to purchase new investments; to fund new business
ventures; and to pay normal operating expenditures and taxes. The Company's main
sources of funds are premiums and deposits on insurance and annuity products;
proceeds from the sale of investments; income from investments; and repayments
of investment principal.

      In managing its general account and fixed separate account assets in
relation to its liabilities, the Company has segmented these assets by product
or by groups of products. The Company manages each segment's assets based on an
investment policy that it has established for that segment. Among other matters,
this investment policy considers liquidity requirements and provides cash flow
estimates. The Company reviews these policies quarterly.

      The Company's liquidity targets are intended to enable it to meet its
day-to-day cash requirements. On a quarterly basis, the Company compares its
total "liquifiable" assets to its total demand liabilities. Liquifiable assets
comprise cash and assets that could quickly be converted to cash should the need
arise. These assets include short-term investments and other current assets and
investment-grade bonds. The Company's policy is to maintain a liquidity ratio in
excess of 100%, and it did so throughout 1999. Based on its ongoing liquidity
analyses, the Company believes that its available liquidity is more than
sufficient to meet its liquidity needs.

OTHER MATTERS

      DEMUTUALIZATION

      On January 27, 1998, Sun Life (Canada) announced that its Board of
Directors had requested that management develop a plan to demutualize.
Demutualization would involve converting from a mutual structure, with ownership
by policyholders, to a shareholder-owned company. It would provide that the
ownership interest currently held by policyholders be distributed to them in the
form of shares, without affecting their interests as policyholders. In
June 1999, the Sun Life (Canada)'s Board of

                                       49
<PAGE>
Directors approved the demutualization timetable recommended by management, and
on September 28, 1999, Sun Life (Canada)'s Board of Directors approved the
demutualization plan. On December 6, 1999, Sun Life (Canada) received approval
for its demutualization plan from the Michigan Commissioner of Insurance. At a
Special Meeting on December 15, 1999, eligible policyholders of Sun Life
(Canada) voted in favor of the Company's plans to demutualize. Sun Life (Canada)
completed its demutualization on March 22, 2000 and its Initial Public Offering
("IPO") on March 29, 2000. The demutualization of Sun Life (Canada) is not
expected to have any significant impact on the Company.

      SALE OF SUBSIDIARIES

      On February 5, 1999, the Company sold Massachusetts Casualty Insurance
Company ("MCIC"), a disability insurance company, to an unaffiliated party. The
net proceeds of this sale were $34.0 million and the Company realized a post tax
gain of $4.9 million.

      On October 29, 1999, the Company completed the sale of its wholly-owned
subsidiary, New London Trust F.S.B. ("NLT"), for approximately $30.3 million to
an unaffiliated party. The Company realized a post-tax gain of $13.2 million
from this sale. This transaction is not expected to have a significant effect on
the ongoing operations of the Company.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

      This discussion covers market risks associated with investment portfolios
that support the Company's general account liabilities. This discussion does not
cover market risks associated with those investment portfolios that support
separate account products. For these products, the policyholder, rather than the
Company, assumes these market risks.

      GENERAL

      The assets of the general account are available to support general account
liabilities. For purposes of managing these assets in relation to these
liabilities, the Company notionally segments these assets by product or by
groups of products. The Company manages each segment's assets based on an
investment policy that it has established for that segment. The policy covers
the segment's liability characteristics and liquidity requirements, provides
cash flow estimates, and sets targets for asset mix, duration, and quality. Each
quarter, investment and business unit managers review these policies to ensure
that the policies remain appropriate, taking into account each segment's
liability characteristics.

      TYPES OF MARKET RISKS

      The Company's stringent underwriting standards and practices have resulted
in high-quality portfolios and have the effect of limiting credit risk. It is
the Company's policy, for example, not to purchase below-investment-grade
securities. Also, as a matter of investment policy, the Company assumes no
foreign currency or commodity risk; nor does it assume equity price risk except
to the extent that it holds real estate in its portfolios. (At year-end 1999,
investment real estate holdings represented less than 4% of its total general
account portfolio.) The management of interest rate risk exposure is discussed
below.

      INTEREST RATE RISK MANAGEMENT

      The Company's fixed interest rate liabilities are primarily supported by
well-diversified portfolios of fixed interest investments. They are also
supported by holdings of real estate and floating rate notes. All of these fixed
interest investments are held for other than trading purposes and can include
publicly issued and privately placed bonds and commercial mortgage loans. Public
bonds can include Treasury bonds, corporate bonds, and money market instruments.
The Company's fixed income portfolios also hold securitized assets, including
mortgage-backed securities ("MBS") and asset-backed securities. These securities
are subject to the same standards applied to other portfolio investments,
including relative value criteria and diversification guidelines. In portfolios
backing interest-sensitive liabilities, the Company's policy is to limit MBS
holdings to less than 10% of total portfolio assets. In all portfolios, the
Company restricts MBS investments to pass-through securities issued by U.S.
government agencies

                                       50

and to collateralized mortgage obligations, which are expected to exhibit
relatively low volatility. The Company does not engage in lever-aged
transactions and it does not invest in the more speculative forms of these
instruments such as the interest-only, principal-only, inverse floater, or
residual tranches.

      Changes in the level of domestic interest rates affect the market value of
fixed interest assets and liabilities. Segments whose liabilities mainly arise
from the sale of products containing interest rate guarantees for certain terms
are sensitive to changes in interest rates. In these segments, the Company uses
"immunization" strategies, which are specifically designed to minimize the loss
from wide fluctuations in interest rates. The Company supports these strategies
using analytical and modeling software acquired from outside vendors.

      Significant features of the Company's immunization models include:

    - an economic or market value basis for both assets and liabilities;

    - an option pricing methodology;

    - the use of effective duration and convexity to measure interest rate
      sensitivity;

    - the use of key rate durations to estimate interest rate exposure at
      different parts of the yield curve and to estimate the exposure to
      non-parallel shifts in the yield curve.

      The Company's Interest Rate Risk Committee meets monthly. After reviewing
duration analyses, market conditions and forecasts, the Committee develops
specific asset management strategies for the interest-sensitive portfolios.
These strategies may involve managing to achieve small intentional mismatches,
either in terms of total effective duration or for certain key rate durations,
between the liabilities and related assets of particular segments. The Company
manages these mismatches to a tolerance range of plus or minus 0.5.

      Asset strategies may include the use of Treasury futures or interest rate
swaps to adjust the duration profiles for particular portfolios. All derivative
transactions are conducted under written operating guidelines and are marked to
market. Total positions and exposures are reported to the Board of Directors on
a monthly basis. The counterparties to hedging transactions are major highly
rated financial institutions, with respect to which the risk of the Company's
incurring losses related to credit exposures is considered remote.

      Liabilities categorized as financial instruments and held in the Company's
general account at December 31, 1999 had a fair value of $1,024.6 million. Fixed
income investments supporting those liabilities had a fair value of $2,072.1
million at that date. The Company performed a sensitivity analysis on these
interest-sensitive liabilities and assets at December 31, 1999. The analysis
showed that if there were an immediate increase of 100 basis points in interest
rates, the fair value of the liabilities would show a net decrease of $30.6
million and the corresponding assets would show a net decrease of $80.5 million.

      By comparison, liabilities categorized as financial instruments and held
in the Company's general account at December 31, 1998 had a fair value of
$1,538.3 million. Fixed income investments supporting those liabilities had a
fair value of $2,710.1 million at that date. The Company performed a sensitivity
analysis on these interest-sensitive liabilities and assets at December 31,
1998. The analysis showed that if there were an immediate increase of 100 basis
points in interest rates, the fair value of the liabilities would show a net
decrease of $46.3 million and the corresponding assets would show a net decrease
of $113.2 million.

      The Company produced these estimates using computer models. Since these
models reflect assumptions about the future, they contain an element of
uncertainty. For example, the models contain assumptions about future
policyholder behavior and asset cash flows. Actual policyholder behavior and
asset cash flows could differ from what the models show. As a result, the
models' estimates of duration and market values may not reflect what actually
will occur. The models are further limited by the fact that they do not provide
for the possibility that management action could be taken to mitigate adverse
results. The Company believes that this limitation is one of conservatism; that
is, it will tend to cause

                                       51
<PAGE>
the models to produce estimates that are generally worse than one might actually
expect, all other things being equal.

      Based on its processes for analyzing and managing interest rate risk, the
Company believes its exposure to interest rate changes will not materially
affect its near-term financial position, results of operations, or cash flows.

REINSURANCE

      The Company has agreements with Sun Life (Canada) which provide that Sun
Life (Canada) will reinsure the mortality risks of the individual life insurance
contracts sold by the Company. Under these agreements, basic death benefits and
supplementary benefits are reinsured on a yearly renewable term basis and
coinsurance basis, respectively. Reinsurance transactions under these agreements
in 1999 had the effect of decreasing net income from operations by approximately
$1,527,000.

      Effective January 1, 1991, the Company entered into an agreement with Sun
Life (Canada) under which certain individual life insurance contracts issued by
Sun Life (Canada) were reinsured by the Company on a 90% coinsurance basis. Also
effective January 1, 1991 the Company entered into an agreement with Sun Life
(Canada) which provides that Sun Life (Canada) will reinsure the mortality risks
in excess of $500,000 per policy for the individual life insurance contracts
assumed by the Company in the reinsurance agreement described above. Such death
benefits are reinsured on a yearly renewable term basis. The life reinsurance
assumed agreement requires the reinsurer to withhold funds in amounts equal to
the reserves assumed. These agreements had the effect of increasing income from
operations by approximately $24,579,000 for the year ended December 31, 1998.
The Company terminated these agreements effective October 1, 1998, resulting in
an increase in income from operations in 1998 of $65,679,000 which included a
cash settlement.

      The Company has also executed reinsurance agreements with unrelated
companies which provide reinsurance of certain individual life insurance
contracts on a modified coinsurance basis under which all deficiency reserves
are ceded. Reinsurance transactions under this agreement had the effect of
increasing income from operations by $193,000 in 1999.

      During 1999, the Company entered into an agreement with an unrelated
company which provides reinsurance on certain fixed group annuity contracts. The
net effect of this agreement was to increase income from operations by
approximately $3,400,000. Also during 1999, the Company entered into three
agreements with two unrelated companies for the purpose of obtaining stop-loss
coverage of guaranteed minimum death benefit exposure with respect to the
Company's variable annuity business. The net effect of these agreements was to
increase income from operations by approximately $157,000.

RESERVES

      In accordance with the life insurance laws and regulations under which the
Company operates, it is obligated to carry on its books, as liabilities,
actuarially determined reserves to meet its obligations on its outstanding
contracts. Reserves are based on mortality tables in general use in the United
States and are computed to equal amounts that, with additions from premiums to
be received, and with interest on such reserves compounded annually at certain
assumed rates, will be sufficient to meet the Company's policy obligations at
their maturities or in the event of an insured's death. In the accompanying
Financial Statements, these reserves are determined in accordance with statutory
regulations.

INVESTMENTS


      Of the Company's total assets of $19.9 billion at December 31, 1999, 88.1%
($17.6 billion) consisted of unitized and non-unitized separate account assets,
6.1% ($1.2 billion) was invested in bonds and similar securities, 2.7%
($528.9 million) was invested in mortgages, 0.4% ($75.3 million) was invested in
subsidiaries, 0.4% ($94.8 million) was invested in real estate, and the
remaining 2.3% ($456.1 million) was invested in cash and other assets.

COMPETITION

      The Company is engaged in a business that is highly competitive because of
the large number of stock and mutual life insurance companies and other entities
marketing insurance products. According to a 1999 statistical study published by
A.M. Best, the Company ranked 36th among North American life insurance companies
based upon total assets as of December 31, 1998.

EMPLOYEES


      The Company and Sun Life (Canada) have entered into a service agreement
which provides that the latter will furnish the Company, as required, with
personnel as well as certain services and facilities on a cost reimbursement
basis. As of March 31, 2000, the Company had 385 direct employees who are
employed at its Principal Executive Office in Wellesley Hills, Massachusetts and
at its Retirement Products and Services Division in Boston, Massachusetts.


PROPERTIES

      The Company occupies office space owned by it and leased to Sun Life
(Canada), and certain unrelated parties for lease terms not exceeding 5 years.
The Company also occupies office space which it leases from unaffiliated parties
for various lease terms.

STATE REGULATION

      The Company is subject to the laws of the State of Delaware governing life
insurance companies and to regulation by the Commissioner of Insurance of
Delaware. An annual statement is filed with the Commissioner of Insurance on or
before March lst in each year relating to the operations of the Company for the
preceding year and its financial condition on December 31st of such year. Its
books and records are subject to review or examination by the Commissioner or
his agents at any time and a full examination of its operations is conducted at
periodic intervals.

      The Company is also subject to the insurance laws and regulations of the
other states and jurisdictions in which it is licensed to operate. The laws of
the various jurisdictions establish supervisory agencies with broad
administrative powers with respect to licensing to transact business, overseeing
trade practices, licensing agents, approving policy forms, establishing reserve
requirements, fixing maximum interest rates on life insurance policy loans and
minimum rates for accumulation of surrender values, prescribing the form and
content of required financial statements and regulating the type and amounts of
investments permitted. Each insurance company is required to file detailed
annual reports with supervisory agencies in each of the five jurisdictions in
which it does business and its operations and accounts are subject to
examination by such agencies at regular intervals.

      In addition, many states regulate affiliated groups of insurers, such as
the Company, Sun Life (Canada) and its affiliates, under insurance holding
company legislation. Under such laws, inter-company transfers of assets and
dividend payments from insurance subsidiaries may be subject to prior notice or
approval, depending on the size of such transfers and payments in relation to
the financial positions of the companies involved. Under insurance guaranty fund
laws in most states, insurers doing business therein can be assessed (up to
prescribed limits) for policyholder losses incurred by insolvent companies. The
amount of any future assessments of the Company under these laws cannot be
reasonably estimated. However, most of these laws do provide that an assessment
may be excused or deferred if it would threaten an insurer's own financial
strength and many permit the deduction of all or a portion of any such
assessment from any future premium or similar taxes payable.

      Although the federal government generally does not directly regulate the
business of insurance, federal initiatives often have an impact on the business
in a variety of ways. Current and proposed federal measures which may
significantly affect the insurance business include employee benefit regulation,
removal of barriers preventing banks from engaging in the insurance business,
tax law changes affecting the taxation of insurance companies, the tax treatment
of insurance products and its impact on the relative desirability of various
personal investment vehicles.

SUN LIFE ASSURANCE COMPANY OF CANADA (U.S.)
(Wholly-Owned Subsidiary of Sun Life of Canada (U.S.) Holdings, Inc.)

NOTES TO STATUTORY FINANCIAL STATEMENTS

1.  DESCRIPTION OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

GENERAL

Sun Life Assurance Company of Canada (U.S.) (the "Company") is incorporated as a
life insurance company and is currently engaged in the sale of individual
variable life insurance, individual fixed and variable annuities, group fixed
and variable annuities, and group pension contracts.

Effective May 1, 1997, the Company became a wholly-owned subsidiary of the newly
established Sun Life of Canada (U.S.) Holdings, Inc. ("Life Holdco"). On
December 18, 1997, Life Holdco became a wholly-owned subsidiary of Sun Life
Assurance Company of Canada - U.S. Operations Holdings, Inc. ("US Holdco"). US
Holdco is a wholly-owned subsidiary of Sun Life Assurance Company of Canada
("SLOC"), a mutual insurance company.

The Company, which is domiciled in the State of Delaware, prepares its financial
statements in accordance with statutory accounting practices prescribed or
permitted by the State of Delaware Insurance Department. Prescribed accounting
practices include practices described in a variety of publications of the
National Association of Insurance Commissioners ("NAIC"), as well as state laws,
regulations and general administrative rules. Permitted accounting practices
encompass all accounting practices not so prescribed. The permitted accounting
practices adopted by the Company are not material to the financial statements.
Prior to 1996, statutory accounting practices were recognized by the insurance
industry and the accounting profession as generally accepted accounting
principles for mutual life insurance companies and stock life insurance
companies wholly-owned by mutual life insurance companies. In April 1993, the
Financial Accounting Standards Board ("FASB") issued an interpretation (the
"Interpretation"), that became effective in 1996, which changed the previous
practice of mutual life insurance companies (and stock life insurance companies
that are wholly-owned subsidiaries of mutual life insurance companies) with
respect to utilizing statutory basis financial statements for general purposes,
in that it will no longer allow such financial statements to be described as
having been prepared in conformity with generally accepted accounting principles
("GAAP"). Consequently, these financial statements prepared in conformity with
statutory accounting practices, as described above, vary from and are not
intended to present the Company's financial position, results of operations or
cash flow in conformity with generally accepted accounting principles. (See Note
19 for further discussion relative to the Company's basis of financial statement
presentation.) The effects on the financial statements of the variances between
the statutory basis of accounting and GAAP, although not reasonably
determinable, are presumed to be material.

INVESTED ASSETS

Bonds are carried at cost, adjusted for amortization of premium or accrual of
discount. Investments in mortgage backed securities are generally carried at
amortized cost. Changes in prepayment assumptions and resulting cash flows are
confirmed retrospectively. The adjusted yield is used to calculate investment
income in future periods. If current book value exceeds future undiscounted cash
flows, a realized capital loss is recorded and amortized through the Interest
Maintenance Reserve (IMR). Investments in non-insurance subsidiaries are carried
on the equity basis. Investments in insurance subsidiaries are carried at their
statutory surplus values. Mortgage loans acquired at a premium or discount are
carried at amortized values and other mortgage loans are carried at the amounts
of the unpaid balances. Real estate investments are carried at the lower of
cost, adjusted for accumulated depreciation or appraised value, less
encumbrances. Short-term investments are carried at amortized cost, which
approximates fair value. Depreciation of buildings and improvements is
calculated using the straight-line method over the estimated useful life of the
property, generally 40 to 50 years.

YEARS ENDED DECEMBER 31, 1999, 1998 AND 1997

1.  DESCRIPTION OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING
POLICIES (CONTINUED)
POLICY AND CONTRACT RESERVES

The reserves for life insurance and annuity contracts are computed in accordance
with presently accepted actuarial standards, and are based on actuarial
assumptions and methods (including use of published mortality tables and
prescribed interest rates) which produce reserves at least as great as those
required by law and contract provisions.

INCOME AND EXPENSES

For life and annuity contracts, premiums are recognized as revenues over the
premium paying period, whereas commissions and other costs applicable to the
acquisition of new business are charged to operations as incurred.

SEPARATE ACCOUNTS

The Company has established unitized separate accounts applicable to various
classes of contracts providing for variable benefits. Contracts for which funds
are invested in separate accounts include variable life insurance and individual
and group qualified and non-qualified variable annuity contracts.

The Company has also established a non-unitized separate account for amounts
allocated to the fixed portion of certain combination fixed/variable deferred
annuity contracts. The assets of this account are available to fund general
account liabilities, and general account assets are available to fund
liabilities of this account.

Assets and liabilities of the separate accounts, representing net deposits and
accumulated net investment earnings less fees, held primarily for the benefit of
contract holders, are shown as separate captions in the financial statements.
Assets held in the separate accounts are carried at market value as determined
by quoted market prices of the underlying investments.

Gains (losses) from mortality experience and investment experience of the
separate accounts, not applicable to contract owners, and accrued expense
allowances recognized in reserves are receivable from or payable to the general
account. Accumulated amounts that have not been transferred are recorded as a
payable (receivable) to (from) the general account. Amounts payable to the
general account of the Company were $467,619,000 in 1999 and $361,863,000 in
1998.

CHANGES IN ACCOUNTING PRINCIPLES AND REPORTING

As described more fully in Note 10, during 1997 the Company changed certain
assumptions used in determining actuarial reserves.

In March 1998, the National Association of Insurance Commissioners adopted the
Codification of Statutory Accounting Principles ("Codification"). The
Codification, which is intended to standardize regulatory accounting and
reporting for the insurance industry, is proposed to be effective January 1,
2001. However, statutory accounting principles will continue to be established
by individual state laws and permitted practices and it is uncertain when, or
if, the state of Delaware will require adoption of Codification for the
preparation of statutory financial statements. The Company has not finalized the
quantification of the effects of Codification on its statutory financial
statements.

OTHER

Preparation of the financial statements requires management to make estimates
and assumptions that affect reported amounts of assets, liabilities, revenues
and expenses. Actual results could differ from those estimates.

Certain prior year amounts have been reclassified to conform to amounts as
presented in the current year.

6.  INVESTMENT GAINS AND LOSSES (CONTINUED)
Realized capital gains and losses on bonds and mortgages and interest rate swaps
which relate to changes in levels of interest rates are charged or credited to
an interest maintenance reserve ("IMR") and amortized into income over the
remaining contractual life of the security sold. The net realized capital gains
credited to the interest maintenance reserve were $4,965,000 in 1999, $8,943,000
in 1998, and $6,321,000 in 1997. All gains and losses are transferred net of
applicable income taxes.

8.  DERIVATIVES

The Company uses derivative instruments for interest rate risk management
purposes, including hedges against specific interest rate risk and to minimize
the Company's exposure to fluctuations in interest rates and foreign currency
exchange rates. The Company's use of derivatives has included U.S. Treasury
futures, conventional interest rate swaps, and currency and interest rate swap
agreements structured as forward spread lock interest rate swaps.

In the case of interest rate futures, gains or losses on contracts that qualify
as hedges are deferred until the earliest of the completion of the hedging
transaction, determination that the transaction will no longer take place, or
determination that the hedge is no longer effective. Upon completion of the
hedge, where it is impractical to allocate gains or losses to specific hedged
assets or liabilities, gains or losses are deferred in IMR and amortized over
the remaining life of the hedged assets. At December 31, 1999 and 1998, there
were no futures contracts outstanding.

In the case of interest rate and foreign currency swap agreements and forward
spread lock interest rate swap agreements, gains or losses on terminated swaps
are deferred in IMR and amortized over the shorter of the remaining life of the
hedged asset or the remaining term of the swap contract. The net differential to
be paid or received on interest rate swaps is recorded monthly as interest rates
change.

</TABLE>

The market value of swaps is the estimated amount that the Company would receive
or pay on termination or sale, taking into account current interest rates and
the current creditworthiness of the counterparties. The Company is exposed to
potential credit loss in the event of nonperformance by counterparties. The
counterparties are major financial institutions and management believes that the
risk of incurring losses related to credit risk is remote.

9.  LEVERAGED LEASES

The Company is a lessor in a leveraged lease agreement entered into on
October 21, 1994, under which equipment having an estimated economic life of
25-40 years was leased for a term of 9.75 years. The Company's equity investment
represented 22.9% of the purchase price of the equipment. The balance of the
purchase price was furnished by third-party long-term debt financing,
collateralized by the equipment and non-recourse to the Company. At the end of
the lease term, the Master Lessee may exercise a fixed price purchase option to
purchase the equipment.

The Company's net investment in leveraged leases is composed of the following
elements:

10. REINSURANCE

The Company has agreements with SLOC which provide that SLOC will reinsure the
mortality risks of the individual life insurance contracts sold by the Company.
Under these agreements basic death benefits and supplementary benefits are
reinsured on a yearly renewable term basis and coinsurance basis, respectively.
Reinsurance transactions under these agreements had the effect of decreasing
income from operations by approximately $1,527,000, $2,128,000 and $1,381,000
for the years ended December 31, 1999, 1998 and 1997, respectively.

Effective January 1, 1991, the Company entered into an agreement with SLOC under
which certain individual life insurance contracts issued by SLOC were reinsured
by the Company on a 90% coinsurance basis. During 1997, SLOC changed certain
assumptions used in determining the gross and the ceded reserve balance. The
Company reflected the effect of the changes in assumptions to its assumed
reserves as a direct credit to surplus. The effect of the change was a
$39,016,000 decrease in reserves. Also, the agreement required SLOC to reinsure
the mortality risks in excess of $500,000 per policy for the individual life
insurance contracts assumed by the Company. Such death benefits are reinsured on
a yearly renewable term basis. The life reinsurance assumed agreement required
the reinsurer to withhold funds in amounts equal to the reserves assumed. These
agreements had the effect of increasing income from operations by approximately
$24,579,000, and $37,050,000 for the years ended December 31, 1998 and 1997,
respectively. The Company terminated this agreement effective October 1, 1998,
resulting in an increase in income from operations of $65,679,000 which included
a cash settlement.

The following are summarized pro-forma results of operations of the Company for
the years ended December 31, 1999, 1998 and 1997 before the effect of
reinsurance transactions with SLOC:

</TABLE>

The Company has an agreement with an unrelated company which provides
reinsurance of certain individual life insurance contracts on a modified
coinsurance basis and under which all deficiency reserves related to these
contracts are reinsured. Reinsurance transactions under this agreement had the
effect of increasing income from operations by $193,000 in 1999, $3,008,000 in
1998, and decreasing income from operations by $2,658,000 in 1997.

During 1999 the Company entered into an agreement with an unrelated company
which provides reinsurance on certain fixed group annuity contracts. The net
effect of this agreement was to increase income from operations by approximately
$3,400,000. Also during 1999, the Company entered into three agreements with two
unrelated companies for the purpose of obtaining stop-loss coverage of
guaranteed minimum death benefit exposure with respect to the Company's variable
annuity business. The net effect of these agreements was to increase income from
operations by approximately $157,000.

10. REINSURANCE (CONTINUED)
The Company is contingently liable for the portion of the policies reinsured
under each of its existing reinsurance agreements in the event the reinsurance
companies are unable to pay their portion of any reinsured claim. Management
believes that any liability from this contingency is unlikely. However, to limit
the possibility of such losses, the Company evaluates the financial condition of
its reinsurers and monitors concentration of credit risk.

13. RETIREMENT PLANS

The Company participates with SLOC in a noncontributory defined benefit pension
plan covering essentially all employees. The benefits are based on years of
service and compensation.

The funding policy for the pension plan is to contribute an amount, which at
least satisfies the minimum amount required by ERISA; currently, the plan is
fully funded. The Company is charged for its share of the pension cost based
upon its covered participants. Pension plan assets consist principally of
separate accounts of SLOC.

The Company's share of the group's accrued pension obligation was $1,914,000,
and $1,178,000 at December 31, 1999 and 1998, respectively. The Company's share
of net periodic pension cost was $736,000, $586,000, and $146,000 for 1999, 1998
and 1997, respectively.

The Company also participates with SLOC and certain affiliates in a 401(k)
savings plan for which substantially all employees are eligible. The Company
matches, up to specified amounts, employees' contributions to the plan. Company
contributions were $284,000, $231,000, and $259,000 for the years ended
December 31, 1999, 1998 and 1997, respectively.

OTHER POST-RETIREMENT BENEFIT PLANS

In addition to pension benefits the Company provides certain health, dental, and
life insurance benefits ("post-retirement benefits") for retired employees and
dependents. Substantially all employees may become eligible for these benefits
if they reach normal retirement age while working for the Company, or retire
early upon satisfying an alternate age plus service condition. Life insurance
benefits are generally set at a fixed amount.

13. RETIREMENT PLANS (CONTINUED)
The Company records an accrual of the estimated cost of retiree benefit payments
during the years the employee provides services, and amortizes an obligation of
approximately $400,000 over a period of ten years. The Company's cash flows are
not affected by this method, however the net effect decreased income by
$185,000, $95,000, and $117,000, for the years ended December 31, 1999, 1998,
and 1997, respectively. The Company's post-retirement health, dental and life
insurance benefits currently are not funded.

The following table sets forth the change in the pension and other
post-retirement benefit plans' benefit obligations and assets as well as the
plans' funded status reconciled with the amount shown in the Company's financial

</TABLE>

The major methods and assumptions used in estimating the fair values of
financial instruments are as follows:

The fair values of short-term bonds are estimated to be the amortized cost. The
fair values of long-term bonds which are publicly traded are based upon market
prices or dealer quotes. For privately placed bonds, fair values are estimated
by taking into account prices for publicly traded bonds of similar credit risk
and maturity and repayment and liquidity characteristics.

The fair values of mortgages are estimated by discounting future cash flows
using current rates at which similar loans would be made to borrowers with
similar credit ratings and for the same remaining maturities.

The fair values of policy loans approximate carrying amounts.

The fair values of derivative financial instruments are estimated using the
process described in Note 8.

The fair values of the Company's general account insurance reserves and
liabilities under investment-type contracts (insurance, annuity and pension
contracts that do not involve mortality or morbidity risks) are estimated using
discounted cash flow analyses or surrender values. Those contracts that are
deemed to have short-term guarantees have a carrying amount equal to the
estimated fair value.

15. STATUTORY INVESTMENT VALUATION RESERVES

The asset valuation reserve ("AVR") provides a reserve for losses from
investments in bonds, stocks, mortgage loans, real estate and other invested
assets with related increases or decreases being recorded directly to surplus.

Realized capital gains and losses on bonds and mortgages which relate to changes
in levels of interest rates are charged or credited to an interest maintenance
reserve and amortized into income over the remaining contractual life of the
security sold.

The table shown below presents changes in the major elements of the AVR and IMR.

16. FEDERAL INCOME TAXES

The Company, its subsidiaries and certain other affiliates file a consolidated
federal income tax return. Federal income taxes are calculated for the
consolidated group based upon amounts determined to be payable as a result of
operations within the current year. No provision is recognized for timing
differences which may exist between financial statement and taxable income. Such
timing differences include reserves, depreciation and accrual of market discount
on bonds. Cash payments for federal income taxes were approximately $3,000,000,
$48,144,000, and $31,000,000 for the years ended December 31, 1999, 1998 and
1997, respectively.

The Company is currently undergoing an audit by the Internal Revenue Service.
The Company believes that there will be no material audit adjustments for the
periods under examination.

17. RELATED PARTY TRANSACTIONS
A. SURPLUS NOTES AND NOTES RECEIVABLE (PAYABLE)

On December 22, 1997, the Company issued a $250,000,000 surplus note to Life
Holdco. This note has an interest rate of 8.625% and is due on or after
November 6, 2027.

On May 9, 1997, the Company issued a short-term note of $600,000,000 to Life
Holdco at an interest rate of 5.10%, which was extended at various interest
rates. This note was repaid on December 22, 1997.

On December 19, 1995, the Company issued surplus notes totaling $315,000,000 to
an affiliate, Sun Canada Financial Co., at interest rates between 5.75% and
7.25%. Of these notes, $157,500,000 will mature in the year 2007 and
$157,500,000 will mature in the year 2015. Interest on these notes is payable
semiannually.

Principal and interest on surplus notes are payable only to the extent that the
Company meets specified requirements regarding free surplus exclusive of the
principal amount and accrued interest, if any, on these notes and with the
consent of the Delaware Insurance Commissioner.

The Company accrued $4,259,000 and $4,259,000 for interest on surplus notes for
the years ended December 31, 1999 and 1998, respectively.

December 21,1999.

B.  STOCKHOLDER DIVIDENDS

The maximum amount of dividends which can be paid by the Company without prior
approval of the Insurance Commissioner of the State of Delaware is subject to
restrictions relating to statutory surplus. In 1999, a dividend in the amount of
$80,000,000 was declared and paid by the Company to its parent, Life Holdco.
This dividend was approved by the Board of Directors, but did not require
approval of the Insurance Commissioner. In 1998, a dividend in the amount of
$50,000,000 was declared and paid by the Company to its parent, Life Holdco.
This dividend was approved by the Insurance Commissioner and the Board of
Directors. On December 24, 1997 the Company transferred all of its shares of MFS
to Life Holdco in the form of a dividend valued at $159,722,000. This dividend
was approved by the Insurance Commissioner and the Board of Directors.

C.  SERVICE AGREEMENTS

The Company has an agreement with SLOC which provides that SLOC will furnish, as
requested, personnel as well as certain services and facilities on a
cost-reimbursement basis. Expenses under this agreement amounted to
approximately $28,700,000 in 1999, $16,344,000 in 1998, and $15,997,000 in 1997.

The Company leases office space to SLOC under lease agreements with terms
expiring in December, 2004 and options to extend the terms for each of twelve
successive five-year terms at fair market rental not to exceed 125% of the fixed
rent for the term which is ending. Rent received by the Company under the leases
for 1999 amounted to approximately $6,943,000.

18. RISK-BASED CAPITAL

Effective December 31, 1993, the NAIC adopted risk-based capital requirements
for life insurance companies. The risk-based capital requirements provide a
method for measuring the minimum acceptable amount of adjusted capital that a
life insurer should have, as determined under statutory accounting

practices, taking into account the risk characteristics of its investments and
products. The Company has met the minimum risk-based capital requirements at
December 31, 1999, 1998 and 1997.

19. COMMITMENTS AND CONTINGENT LIABILITIES

The Company is involved in pending and threatened litigation in the normal
course of its business in which claims for monetary and punitive damages have
been asserted. Although there can be no assurances, at the present time the
Company does not anticipate that the ultimate liability arising from such
pending or threatened litigation, after consideration of provisions made for
potential losses and costs of defense, will have a material adverse effect on
the financial condition or operating results of the Company.

Under insurance guaranty fund laws in each state, the District of Columbia and
Puerto Rico, insurers licensed to do business can be assessed by state insurance
guaranty associations for certain obligations of insolvent insurance companies
to policyholders and claimants. Recent regulatory actions against certain large
life insurers encountering financial difficulty have prompted various state
insurance guaranty associations to begin assessing life insurance companies for
the deemed losses. Most of these laws do provide, however, that an assessment
may be excused or deferred it it would threaten an insurer's solvency and
further provide annual limits on such assessments. Part of the assessments paid
by the Company and its subsidiaries pursuant to these laws may be used as
credits for a portion of the associated premium taxes. The Company incurred
guaranty fund assessments of approximately $3,500,000, $3,500,000, and
$3,083,000 in 1999, 1998 and 1997, respectively.

20. ACCOUNTING POLICIES AND PRINCIPLES

The financial statements of the Company have been prepared on the basis of
statutory accounting practices which, prior to 1996, were considered by the
insurance industry and the accounting profession to be in accordance with GAAP
for mutual life insurance companies. The primary differences between statutory
accounting practices and GAAP are described as follows. Under statutory
accounting practices, financial statements are not consolidated and investments
in subsidiaries are shown at net equity value. Accordingly, the assets,
liabilities and results of operations of the Company's subsidiaries are not
consolidated with the assets, liabilities and results of operations,
respectively, of the Company. Changes in net equity value of the common stock of
the Company's United States life insurance subsidiaries are directly reflected
in the Company's surplus. Changes in the net equity value of the common stock of
all other subsidiaries are directly reflected in the Company's Asset Valuation
Reserve. Dividends paid by subsidiaries to the Company are included in the
Company's net investment income.

Other differences between statutory accounting practices and GAAP include the
following items. Statutory accounting practices do not recognize the following
assets or liabilities which are reflected under GAAP: deferred policy
acquisition costs, deferred federal income taxes and statutory nonadmitted
assets. Asset Valuation Reserves and Interest Maintenance Reserves are
established under statutory accounting practices but not under GAAP. Methods for
calculating real estate depreciation and investment valuation allowances differ
under statutory accounting practices and GAAP. Actuarial assumptions and
reserving methods differ under statutory accounting practices and GAAP. Premiums
for universal life and investment-type products are recognized as income for
statutory purposes and as deposits to policyholders' accounts for GAAP.
Investments in fixed maturity securities classified as available-for-sale are
carried at aggregate fair value with changes in unrealized gains and losses
reported net of taxes in a separate component of stockholder's equity for GAAP
and generally at amortized cost under statutory accounting practices.

on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

As described more fully in Notes 1 and 20 to the financial statements, the
Company prepared these financial statements using accounting practices
prescribed or permitted by the Insurance Department of the State of Delaware,
which is a comprehensive basis of accounting other than generally accepted
accounting principles. The effects on the financial statements of the
differences between the statutory basis of accounting and generally accepted
accounting principles, although not reasonably determinable, are presumed to be
material.

In our opinion, the statutory financial statements referred to above present
fairly, in all material respects, the admitted assets, liabilities, and capital
stock and surplus of Sun Life Assurance Company of Canada (U.S.) as of
December 31, 1999 and 1998, and the results of its operations and its cash flow
for each of the three years in the period ended December 31, 1999 on the basis
of accounting described in Notes 1 and 20.

However, because of the differences between the two bases of accounting referred
to in the second preceding paragraph, in our opinion, the statutory financial
statements referred to above do not present fairly, in conformity with generally
accepted accounting principles, the financial position of Sun Life Assurance
Company of Canada (U.S.) as of December 31, 1999 and 1998 or the results of its
operations or its cash flow for each of the three years in the period ended
December 31, 1999.

                                   APPENDIX A
                                    GLOSSARY

      The following terms as used in this Prospectus have the indicated
meanings:

      ACCOUNT or PARTICIPANT ACCOUNT: An account established for each
Participant to which Net Purchase Payments are credited.

      ACCOUNT VALUE: The Variable Accumulation Value, if any, plus the Fixed
Accumulation Value, if any, of your Account for any Valuation Period.

      ACCOUNT YEAR and ACCOUNT ANNIVERSARY: Your first Account Year is the
period of (a) 12 full calendar months plus (b) the part of the calendar month in
which we issue your Contract (if not on the first day of the month), beginning
with the Contract Date. Your Account Anniversary is the first day immediately
after the end of an Account Year. Each Account Year after the first is the 12
calendar month period that begins on your Account Anniversary. If, for example,
the Contract Date is in March, the first Account Year will be determined from
the Contract Date but will end on the last day of March in the following year;
your Account Anniversary is April 1 and all Account Years after the first will
be measured from April 1.

      ACCUMULATION PHASE: The period before the Annuity Commencement Date and
during the lifetime of the Annuitant during which you make Purchase Payments
under the Contract. This is called the "Accumulation Period" in the Contract.

      ANNUITANT: The person or persons named in the Application and on whose
life the first annuity payment is to be made. In a Non-Qualified Contract, if
you name someone other than yourself as Annuitant, you may also name a
Co-Annuitant. If you do, all provisions of the Contract based on the death of
the Annuitant will be based on the date of death of the last surviving of the
persons named. By example, if the Annuitant dies prior to the Annuity
Commencement Date, the Co-Annuitant will become the new Annuitant. The death
benefit will become due only on the death before the Annuity Commencement Date
of the last surviving Annuitant and Co-Annuitant named. These persons are
referred to collectively in the Contract as "Annuitants." If you have named both
an Annuitant and Co-Annuitant, you may designate one of them to become the sole
annuitant as of the Annuity Commencement Date, if both are living at that time.
In the absence of such designation, the Co-Annuitant will become the sole
Annuitant during the Income Phase.

      *ANNUITY COMMENCEMENT DATE: The date on which the first annuity payment
under each Contract is to be made.

      *ANNUITY OPTION: The method you choose for making annuity payments.

      ANNUITY UNIT: A unit of measure used in the calculation of the amount of
the second and each subsequent Variable Annuity payment from the Variable
Account.

      APPLICATION: The document signed by you or other evidence acceptable to us
that serves as your application for participation under a Group Contract or
purchase of an Individual Contract.

      *BENEFICIARY: The person or entity having the right to receive the death
benefit and, for Non-Qualified Contracts, who is the "designated beneficiary"
for purposes of Section 72(s) of the Internal Revenue Code.

      BUSINESS DAY: Any day the New York Stock Exchange is open for trading.

      CERTIFICATE: The document for each Participant which evidences the
coverage of the Participant under a Group Contract.

      COMPANY: Sun Life Assurance Company of Canada (U.S.).

      CONTRACT DATE: The date on which we issue your Contract. This is called
the "Issue Date" in the Contract.

* You specify these items on the Certificate Specifications page and may change
them, as we describe in this Prospectus.

of Death. If your Beneficiary elects the death benefit payment option, the later
of (a) the date on which we receive the Beneficiary's election and (b) the date
on which we receive Due Proof of Death. If we do not receive the Beneficiary's

Date will be the last day of the 60 day period and we will pay the death benefit
in cash.

                                   APPENDIX C
        WITHDRAWALS, WITHDRAWAL CHARGES AND THE MARKET VALUE ADJUSTMENT

PART 1: VARIABLE ACCOUNT (THE MARKET VALUE ADJUSTMENT DOES NOT APPLY TO THE
VARIABLE ACCOUNT)

WITHDRAWAL CHARGE CALCULATION:

FULL SURRENDER:

      Assume a Purchase Payment of $40,000 is made on the Date of Coverage, no
additional Purchase Payments are made and there are no partial withdrawals. The
table below presents four examples of the withdrawal charge resulting from a
full surrender of the Participant's Account, based on hypothetical Account
Values.

<TABLE>

    1       $ 41,000     $  4,000(a)  $ 37,000   6.00  %      $2,220
    3       $ 52,000     $ 12,000(b)  $ 40,000   5.00  %      $2,000
    7       $ 80,000     $ 28,000(c)  $ 40,000   3.00  %      $1,200
    9       $ 98,000     $ 68,000(d)  $ 40,000   0.00  %      $   0
</TABLE>

- ------------------------

(a) The free withdrawal amount during an Account Year is equal to 10% of new
    Payments (those Payments made in current Account Year or in the 6
    immediately preceding Account Years) less any prior partial withdrawals in
    that Account Year. Any portion of the free withdrawal amount that is not
    used in the current Account Year is carried forward into future years. In
    the first Account Year 10% of new Payments is $4,000. Therefore, on full
    surrender $4,000 is withdrawn free of the withdrawal charge and the Purchase
    Payment liquidated is $37,000 (Account Value less free withdrawal amount).
    The withdrawal charge amount is determined by applying the withdrawal charge
    percentage to the Purchase Payment liquidated.

(b) In the third Account Year, the free withdrawal amount is equal to $12,000
    ($4,000 for the current Account Year, plus an additional $8,000 for Account
    Years 1 and 2 because no partial withdrawals were taken and the unused free
    withdrawal amount is carried forward into future Account Years). The
    withdrawal charge percentage is applied to the liquidated Purchase Payment
    (Account Value less free withdrawal amount).

(c) In the seventh Account Year, the free withdrawal amount is equal to $28,000
    ($4,000 for the current Account Year, plus an additional $24,000 for Account
    Years 1 through 6, $4,000 for each Account Year because no partial
    withdrawals were taken and the unused free withdrawal amount is carried
    forward into future Account Years). The withdrawal charge percentage is
    applied to the liquidated Purchase Payment (Account Value less free
    withdrawal amount, but not greater than actual Purchase Payments).

(d) In Account Year 9, the free withdrawal amount is $68,000, calculated as
    follows: There are no Annual Withdrawal Allowances for Account Years 8 or 9
    because there are no New Payments in those years. The $40,000 Purchase
    Payment made in Account Year 1 is now an Old Payment that constitutes a
    portion of the free withdrawal amount. In addition, the unused Annual
    Withdrawal Allowances of $4,000 for each of Account Years 1 through 7 are
    carried forward and available for use in Account Year 9. The $98,000 full
    withdrawal is attributed first to the free withdrawal amount. Because the
    remaining $30,000 is not withdrawn from New Payments, this part of the
    withdrawal also will not be subject to the withdrawal charge.

PARTIAL WITHDRAWAL:

      Assume a single Purchase Payment of $40,000 is deposited at issue, no
additional Purchase Payments are made, no partial withdrawals have been taken
prior to the fifth Account Year, and there

                                       87
<PAGE>
are a series of three partial withdrawals made during the fifth Account Year of
$9,000, $12,000, and $15,000.

 (c)   $ 40,000    $ 15,000   $      0   $ 15,000   4.00  %      $600
</TABLE>

- ------------------------

(a) The free withdrawal amount during an Account Year is equal to 10% of new
    Payments (those Payments made in current Account Year or in the 6
    immediately preceding Account Years) less any prior partial withdrawals in
    that Account Year. Any portion of the free withdrawal amount that is not
    used in the current Account Year is carried forward into future years. In
    the fifth Account Year, the free withdrawal amount is equal to $20,000
    ($4,000 for the current Account Year, plus an additional $16,000 for Account
    Years 1 through 4, $4,000 for each Account Year because no partial
    withdrawals were taken). The partial withdrawal amount ($9,000) is less than
    the free withdrawal amount so no Purchase Payments are liquidated and no
    withdrawal charge applies.

(b) Since a partial withdrawal of $9,000 was taken, the remaining free
    withdrawal amount is equal to $11,000. The $12,000 partial withdrawal will
    first be applied against the $11,000 free withdrawal amount, and then will
    liquidate Purchase Payments of $1,000, incurring a withdrawal charge of $40.

(c) The free withdrawal amount is zero since the previous partial withdrawals
    have already used the free withdrawal amount. The entire partial withdrawal
    amount will result in Purchase Payments being liquidated and will incur a
    withdrawal charge. At the beginning of the next Account Year, 10% of
    Purchase Payments would be available for withdrawal requests during that
    Account Year.

PART 2 -- FIXED ACCOUNT -- EXAMPLES OF THE MARKET VALUE ADJUSTMENT (MVA)

      The MVA factor is:

<TABLE>
                    <C> <C>   <S> <C>  <C>
                                  N/12
                        1 + I
                      ( ----- )        -1
                        1 + J
</TABLE>

      These examples assume the following:

        1)  The Guarantee Amount was allocated to a five year Guarantee Period
            with a Guaranteed Interest Rate of 6% or .06 (l).

        2)  The date of surrender is two years from the Expiration Date (N =
            24).

        3)  The value of the Guarantee Amount on the date of surrender is
            $11,910.16.

        4)  The interest earned in the current Account Year is $674.16.

        5)  No transfers or partial withdrawals affecting this Guarantee Amount
            have been made.

        6)  Withdrawal charges, if any, are calculated in the same manner as
            shown in the examples in Part 1.

                                       88
<PAGE>
EXAMPLE OF A NEGATIVE MVA:

      Assume that on the date of surrender, the current rate (J) is 8% or .08.

<TABLE>
    <C>              <C> <S> <C>     <C> <C>   <C>
                                         N/12
                              1 + l
    The MVA factor =     (    -----  )         -1
                              1 + J
                                         24/12
                             1 + .06
                   =     (   ------  )         -1
                             1 + .08

                   =     (.981)(2) -1

                   =     .963 -1

                   =     -.037
</TABLE>

      The value of the Guarantee Amount less interest credited to the Guarantee
Amount in the current Account Year is multiplied by the MVA factor to determine
the MVA:

                   ($11,910.16 - $674.16) X (-.037) = -$415.73

      -$415.73 represents the MVA that will be deducted from the value of the
Guarantee Amount before the deduction of any withdrawal charge.

      For a partial withdrawal of $2,000 from this Guarantee Amount, the MVA
would be ($2,000.00 - $674.16) X (-.037) = -$49.06. -$49.06 represents the MVA
that will be deducted from the partial withdrawal amount before the deduction of
any withdrawal charge.

EXAMPLE OF A POSITIVE MVA:

Assume that on the date of surrender, the current rate (J) is 5% or .05.

                                   N/12
                          1 + l
    The MVA factor =   (  -----  )       -1
                          1 + J
                                   24/12
                         1 + .06
                   =   ( ------  )       -1
                         1 + .05

                   =   (1.010)(2) -1

                   =   1.019 -1

                   =   .019

      The value of the Guarantee Amount less interested credited to the
Guarantee Amount in the current Account Year is multiplied by the MVA factor to
determine the MVA:

                     ($11,910.16 - $674.16) X .019 = $213.48

      $213.48 represents the MVA that would be added to the value of the
Guarantee Amount before the deduction of any withdrawal charge.

      For a partial withdrawal of $2,000 from this Guarantee Amount, the MVA
would be ($2,000.00 - $674.16) X .019 = $25.19.

      $25.19 represents the MVA that would be added to the value of the partial
withdrawal amount before the deduction of any withdrawal charge.
