PROFILE             THIS PROFILE IS A SUMMARY OF SOME OF THE MORE IMPORTANT
DECEMBER 28,        POINTS THAT YOU SHOULD KNOW AND CONSIDER BEFORE PURCHASING
1998                THE PIONEER C-VISION VARIABLE ANNUITY CONTRACT. THE CONTRACT
                    IS MORE FULLY DESCRIBED LATER IN THIS PROSPECTUS. PLEASE
                    READ THE PROSPECTUS CAREFULLY.
 
1. THE PIONEER C-VISION VARIABLE ANNUITY CONTRACT
 
The Pioneer C-Vision variable annuity contract is a contract between you, the
owner, and Allmerica Financial Life Insurance and Annuity Company (for contracts
issued in the District of Columbia, Puerto Rico, the Virgin Islands and any
state except Hawaii and New York) or First Allmerica Financial Life Insurance
Company (for contracts issued in Hawaii and New York). It is designed to help
you accumulate assets for your retirement or other important financial goals on
a tax-deferred basis. The Pioneer C-Vision contract combines the concept of
professional money management with the attributes of an annuity contract.
 
Pioneer C-Vision offers a diverse selection of investment portfolios. You may
allocate your payments among any of twelve investment portfolios of the Pioneer
Variable Contracts Trust, the Guarantee Period Accounts and the Fixed Account
(the Guarantee Period Accounts and/or the Fixed Account may not be available in
certain jurisdictions.) This range of investment choices enables you to allocate
your money to meet your particular investment needs.
 
Like all annuities, the contract has an ACCUMULATION PHASE and an ANNUITY PAYOUT
PHASE. During the ACCUMULATION PHASE you can make payments into the contract on
any frequency. Investment and interest gains accumulate tax deferred. You may
withdraw money from your contract during the ACCUMULATION PHASE. However, as
with other tax-deferred investments, you pay taxes on earnings and any untaxed
payments to the contract when you withdraw them. A federal tax penalty may apply
if you withdraw money prior to age 59 1/2.
 
During the ANNUITY PAYOUT PHASE you, or the payee you designate, will receive
regular annuity benefit payments from your contract, provided you annuitize.
Annuitization involves beginning a series of payments from the capital that has
built up in your contract. The amount of your payments during the annuity payout
phase will, in part, be determined by your contract's growth during the
accumulation phase.
 
2. ANNUITY BENEFIT PAYMENTS
 
If you choose to annuitize your contract, you may select one of six annuity
options: (1) monthly payments guaranteed for the annuitant's lifetime; (2)
monthly payments guaranteed for the annuitant's lifetime, but for not less than
10 years; (3) monthly payments for the annuitant's lifetime with the guarantee
that, if payments are less than the accumulated value, a refund of the remaining
value will be paid; (4) monthly payments guaranteed for the annuitant's lifetime
and one other indvidual's (i.e. the beneficiary or a joint annuitant) lifetime;
(5) monthly payments guaranteed for the annuitant's lifetime and one other
individual's lifetime with the payment during the lifetime of the survivor being
reduced to 2/3; and (6) monthly payments guaranteed for a specified period of 1
to 30 years.
 
You also need to decide if you want your annuity payments on a variable basis
(i.e., subject to fluctuation based on investment performance), on a fixed basis
(with benefit payments guaranteed at a fixed amount), or on a combination
variable and fixed basis. Once payments begin, the annuity option cannot be
changed.

3. PURCHASING THIS CONTRACT
 
You can buy a contract through your financial representative, who can also help
you complete the proper forms. There is no fixed schedule for making payments
into this contract. Payments are not limited as to frequency, but there are
certain limitations as to amount. Currently, the initial payment must be at
least $25,000 and each subsequent investment must be at least $100.
 
4. INVESTMENT OPTIONS
 
You have full investment control over the contract. You may allocate and
transfer money among the following investment options:
 
<TABLE>
<S>                                  <C>
Emerging Markets Portfolio           Equity-Income Portfolio
International Growth Portfolio       Balanced Portfolio
Europe Portfolio                     Swiss Franc Bond Portfolio
Capital Growth Portfolio             America Income Portfolio
Growth Shares Portfolio              Money Market Portfolio
Real Estate Growth Portfolio         Guarantee Period Accounts
Growth and Income Portfolio          Fixed Account
</TABLE>
 
The Guarantee Period Accounts let you choose from among several different
Guarantee Periods during which principal and interest rates are guaranteed. The
Fixed Account guarantees principal and a minimum rate of interest (never less
than 3% compounded annually).
 
5. EXPENSES
 
Each year and upon surrender, a $35 contract fee is deducted from your contract.
The contract fee is waived if the value of the contract is $75,000 or more.
(This fee may vary by state. See your contract for more information.) We also
deduct insurance charges which amount to 1.40% annually of the daily value of
your contract value allocated to the variable investment options. These
insurance charges include a mortality and expense risk charge of 1.25% and an
administrative expense charge of 0.15%. There are also investment management
fees and other portfolio operating expenses that vary by portfolio.
 
In states where premium taxes are imposed, a premium tax charge will be deducted
either when withdrawals are made or annuity payments commence. However, the
Company reserves the right to deduct the premium tax charge at the time payment
into the contract is received.
 
There is currently no charge for transfers between investment options. We
reserve the right to assess a charge, not to exceed $25, for transfers in excess
of 12 per year.
 
The following chart is designed to help you understand the charges in your
contract. The column "Total Annual Charges" shows the total of the contract fee
(which is represented as 0.04%), the 1.40% insurance charges and the investment
charges for each portfolio. The next two columns show two examples of the
charges, in dollar amounts, you would pay under a contract. The examples assume
that you invested $1,000 in a portfolio earning 5% annually and that you
withdraw your money: (1) at the end of year 1, and (2) at the end of year 10.
For year 1, the Total Annual Charges are assessed for one year. For year 10, the
example shows the aggregate of all the annual charges assessed for 10 years. The
premium tax is assumed to be 0% in both
 
                                      P-2

examples. The chart does not reflect the optional Enhanced Death Benefit Rider
charge of 0.25% which, if elected, would increase expenses.

The above insurance charges include the annual contract fee (which is
represented as 0.04%).
 
*Portfolio expenses are estimated for the Growth Shares and Growth and Income
Portfolios which commenced operations on October 31, 1997 and for the Emerging
Markets and Europe Portfolios which commenced operations on October 30, 1998. In
addition, Pioneer Investment Management, Inc. has agreed voluntarily to waive
its management fee and/or make other arrangements, if necessary, to reduce
portfolio expenses. For more information, see the Fee Table in the Prospectus
for the Contract.
 
6. TAXES
 
You will not pay taxes until you withdraw money from your contract under current
tax rules. During the accumulation phase, earnings are withdrawn first and are
taxed as ordinary income. If you make a withdrawal prior to age 59 1/2, you may
be subject to a 10% federal tax penalty on the earnings. Payments during the
annuity payout phase are considered partly a return of your investment and
partly earnings. You will be subject to income taxes on the earnings portion of
each payment. However, if your contract is funded with pre-tax or tax deductible
dollars (such as a pension or profit sharing plan contribution), then the entire
payment will be taxable.
 
7. WITHDRAWALS
 
You can withdraw money from your contract at any time during the accumulation
phase. The minimum withdrawal amount is $100.
 
Any withdrawal from a Guarantee Period Account ("GPA") prior to the end of the
guarantee period will be subject to a market value adjustment which may increase
or decrease the value in the account. This adjustment will never impact your
original investment, nor will earnings in the GPA amount to less than an
effective annual rate of 3%.
 
8. PERFORMANCE
 
The following chart illustrates past returns for the portfolios since the
inception of each Sub-Account that has been in existence for a complete calendar
year. The performance figures reflect the contract fee, the insurance

charges, the investment charges and all other expenses of the portfolio. They do
not reflect the optional Enhanced Death Benefit Rider charge of 0.25% which, if
elected, would reduce such performance. Please note that past performance is not
a guarantee of future results.

9. DEATH BENEFIT
 
If you, a joint owner or (in the event that the owner is a non-natural person)
an annuitant dies during the accumulation phase, we will pay the beneficiary a
death benefit. The death benefit is equal to the greater of: (a) the accumulated
value increased by any positive market value adjustment; or (b) gross payments,
decreased proportionately to reflect withdrawals. You may also purchase a rider
that will enhance the death benefit (see "Optional Enhanced Death Benefit Rider"
below).
 
10. OTHER INFORMATION
 
OPTIONAL ENHANCED DEATH BENEFIT RIDER:  This optional rider is available for a
separate monthly charge. Under this rider:
 
I. If an owner (or an annuitant if the owner is a non-natural person) dies
during the accumulation phase and before the oldest owner's 90th birthday, the
death benefit will be equal to the greatest of:
 
                                      P-4
<PAGE>
(a) the accumulated value increased by any positive market value adjustment (the
    "accumulated value"); or
 
(b) gross payments compounded daily at an annual rate of 5%, starting on the
    date each payment is applied, decreased proportionately to reflect
    withdrawals (5% compounding not available in Hawaii and New York); or
 
(c) the highest accumulated value of all contract anniversaries, as determined
    after the accumulated value of each contract anniversary is increased for
    subsequent payments and decreased proportionately for subsequent
    withdrawals.
 
The (c) value is determined on each contract anniversary. A snapshot is taken of
the current (a) value and compared to snapshots taken of the (a) value on all
prior contract anniversaries, AFTER all of the (a) values have been adjusted to
reflect subsequent payments and decreased proportionately for subsequent
withdrawals. The highest of all of these adjusted (a) values then becomes the
(c) value. This (c) value becomes the floor below which the death benefit will
not drop and is locked-in until the next contract anniversary. The values of (b)
and (c) will be decreased proportionately if withdrawals are taken.
 
II. If an owner (or an annuitant if the owner is a non-natural person) dies
during the accumulation phase but after the oldest owner's 90th birthday, the
death benefit will be equal to the greater of:
 
(a) the accumulated value increased by any positive market value adjustment; or
 
(b) the death benefit, as calculated under I, that would have been payable on
    the contract anniversary immediately prior to the oldest owner's 90th
    birthday, increased for subsequent payments and decreased proportionately
    for subsequent withdrawals.
 
FREE-LOOK PERIOD:  If you cancel your contract within 10 days after receiving it
(or whatever period is required by your state), you will receive a refund in
accordance with the terms of the contract's "Right to Examine" provision.
 
DOLLAR COST AVERAGING:  You may elect to automatically transfer money on a
periodic basis from the America Income Portfolio, Money Market Portfolio or
Fixed Account to one or more of the other investment options, except the Fixed
Account and the Guarantee Period Accounts.
 
AUTOMATIC ACCOUNT REBALANCING:  You may elect to automatically have your
contract's accumulated value periodically reallocated ("rebalanced") among your
chosen investment options to maintain your designated percentage allocation mix.
 
PROBATE FREE:  In most cases, the death benefit is payable to the beneficiary
you select without having to go through probate.

In most jurisdictions, values also may be allocated on a fixed basis to the
Fixed Account, which is part of the Company's General Account and, during the
accumulation period, to one or more of the Guarantee Period Accounts. Amounts
allocated to the Fixed Account earn interest at a guaranteed rate for one year
from the date allocated. Amounts allocated to a Guarantee Period Account earn a
fixed rate of interest for the duration of the applicable Guarantee Period. The
interest earned is guaranteed if held for the entire Guarantee Period. If
withdrawn or transferred prior to the end of the Guarantee Period, the value may
be increased or decreased by a Market Value Adjustment. Assets supporting
allocations to the Guarantee Period Accounts in the accumulation phase are held
in the Company's Separate Account GPA.

                                    SUMMARY
 
WHAT IS THE PIONEER C-VISION VARIABLE ANNUITY?
 
The Pioneer C-Vision variable annuity contract is an insurance contract designed
to help you, the Owner, accumulate assets for your retirement or other important
financial goals on a tax-deferred basis. The Contract combines the concept of
professional money management with the attributes of an annuity contract.
Features available through the Contract include:
 
- - a customized investment portfolio;
 
- - experienced professional investment advisers;
 
- - tax deferral on earnings;
 
- - guarantees that can protect your family during the accumulation phase;
 
- - income that can be guaranteed for life;
 
- - issue age up to the 90th birthday of the oldest person among the Owner(s) and
  the Annuitant(s).
 
The Contract has two phases: an accumulation phase and, if you choose to
annuitize, an annuity payout phase. During the accumulation phase, your initial
payment and any additional payments you choose to make may be allocated among
the Sub-Accounts investing in the Portfolios of the Pioneer Variable Contracts
Trust (the "Fund"), to the Guarantee Period Accounts, and to the Fixed Account.
You select the investment options most appropriate for your investment needs. As
those needs change, you may also change your allocation without incurring any
tax consequences. The Contract's Accumulated Value is based on the investment
performance of the Portfolios and any accumulations in the Guarantee Period and
Fixed Accounts. No income taxes are paid on any earnings under the Contract
unless and until Accumulated Values are withdrawn. In addition, during the
accumulation phase, the beneficiaries receive certain protections and guarantees
in the event of your death. See discussion below: "WHAT HAPPENS UPON MY DEATH
DURING THE ACCUMULATION PHASE?"
 
WHAT HAPPENS IN THE ANNUITY PAYOUT PHASE?
 
During the annuity payout phase, you, or the payee you designate, can receive
income based on several annuity payout options. You choose the annuity payout
option and the date for annuity benefit payments to begin. You also decide
whether you want variable annuity benefit payments based on the investment
performance of certain Portfolios, fixed annuity benefit payments with payment
amounts guaranteed by the Company, or a combination of fixed and variable
annuity benefit payments. Among the payout options available during the annuity
payout phase are:
 
- - periodic payments for the Annuitant's lifetime;
 
- - periodic payments for the Annuitant's life and the life of another person
  selected by you;
 
- -periodic payments for the Annuitant's lifetime with any remaining guaranteed
 payments continuing in the event that the Annuitant dies before the end of ten
 years;
 
- -periodic payments over a specified number of years (1 to 30); under this option
 you may reserve the right to convert remaining payments to a lump-sum payout by
 electing a "commutable" option.
 
                                       7
<PAGE>
WHO ARE THE KEY PERSONS UNDER THE CONTRACT?
 
The Contract is between you, (the "Owner"), and us, Allmerica Financial Life
Insurance and Annuity Company (for contracts issued in the District of Columbia,
Puerto Rico, the Virgin Islands and any state except Hawaii and New York) or
First Allmerica Financial Life Insurance Company (for contracts issued in Hawaii
and New York). Unless otherwise specified, any reference to the "Company" in
this Prospectus shall refer exclusively to Allmerica Financial Life Insurance
and Annuity Company for contracts issued in the District of Columbia, Puerto
Rico, the Virgin Islands and any state except Hawaii and New York and
exclusively to First Allmerica Financial Life Insurance Company for contracts
issued in Hawaii and New York. Each Contract has an Owner (or an Owner and a
Joint Owner, in which case one of the two must be an Annuitant), an Annuitant
(or an Annuitant and a Joint Annuitant) and one or more beneficiaries. As Owner,
you make payments, choose investment allocations, receive annuity benefit
payments (or designate someone else to receive annuity benefit payments) and
select the Annuitant and beneficiary. When a Contract is jointly owned, the
consent of both Owners is required in order to exercise any ownership rights.
The Annuitant is the individual upon whose continuation of life annuity benefit
payments involving life contingency depend. An Annuitant may be changed at any
time after issue of the Contract and prior to the Annuity Date, unless (1) the
Owner is a non-natural person or (2) you are taking life expectancy
distributions. For more information about life expectancy distributions, see "F.
Withdrawals." At all times there must be at least one Annuitant. If an Annuitant
dies and a replacement is not named, you will become the new Annuitant. The
beneficiary is the person, persons or entity entitled to the death benefit prior
to the Annuity Date and who, under certain circumstances, may be entitled to
annuity benefit payments upon the death of an Owner on or after the Annuity
Date.
 
HOW MUCH CAN I INVEST AND HOW OFTEN?
 
The number and frequency of payments are flexible, subject only to a $25,000
minimum for the initial payment and a $100 minimum for any additional payments.
In addition, a minimum of $1,000 is always required to establish a Guarantee
Period Account.
 
WHAT ARE MY INVESTMENT CHOICES?
 
The Contract permits net payments to be allocated among the Sub-Accounts, the
Guarantee Period Accounts, and the Fixed Account.
 
THE VARIABLE ACCOUNT.  You have the choice of Sub-Accounts investing in the
twelve Underlying Portfolios of the Fund:
 
<TABLE>
<S>                                  <C>
Emerging Markets Portfolio           Growth Shares Portfolio
International Growth Portfolio       Equity-Income Portfolio
Europe Portfolio                     Balanced Portfolio
Capital Growth Portfolio             Swiss Franc Bond Portfolio
Growth and Income Portfolio          America Income Portfolio
Real Estate Growth Portfolio         Money Market Portfolio
</TABLE>
 
Each Underlying Portfolio operates pursuant to different investment objectives,
discussed below, and this range of investment options enables you to allocate
your money among the Portfolios to meet your particular investment needs.
 
GUARANTEE PERIOD ACCOUNTS.  Assets supporting the guarantees under the Guarantee
Period Accounts are held in the Company's Separate Account GPA, a non-unitized
insulated separate account. Values and benefits calculated on the basis of
Guarantee Period Account allocations, however, are obligations of the Company's
General Account. Amounts allocated to a Guarantee Period Account earn a
Guaranteed Interest Rate declared by the Company. The level of the Guaranteed
Interest Rate depends on the number of years of the Guarantee
 
                                       8
<PAGE>
Period selected. The Company may offer up to nine Guarantee Periods ranging from
two to ten years in duration. Once declared, the Guaranteed Interest Rate will
not change during the duration of the Guarantee Period. If amounts allocated to
a Guarantee Period Account are transferred, surrendered or applied to any
annuity option at any time other than the day following the last day of the
applicable Guarantee Period, a Market Value Adjustment will apply that may
increase or decrease the account's value; however, this adjustment will never be
applied against your principal. In addition, earnings in the GPA after
application of the Market Value Adjustment will not be less than an effective
annual rate of 3%. For more information about the Guarantee Period Accounts and
the Market Value Adjustment, see "GUARANTEE PERIOD ACCOUNTS."
 
THE GUARANTEE PERIOD ACCOUNTS MAY NOT BE AVAILABLE IN ALL STATES.
 
FIXED ACCOUNT.  The Fixed Account is part of the General Account which consists
of all the Company's assets other than those allocated to the Variable Account
and any other separate account. Allocations to the Fixed Account are guaranteed
as to principal and a minimum rate of interest. Additional excess interest may
be declared periodically at the Company's discretion. Furthermore, the initial
rate in effect on the date an amount is allocated to the Fixed Account will be
guaranteed for one year from that date. For more information about the Fixed
Account, see APPENDIX A, "MORE INFORMATION ABOUT THE FIXED ACCOUNT."
 
WHO IS THE INVESTMENT ADVISER FOR THE PORTFOLIOS?
 
Pioneer Investment Management, Inc. ("Pioneer") is the investment adviser to
each Portfolio. Pioneer also provides investment research and portfolio
management services to a number of other retail mutual funds and certain
institutional clients. As of December 31, 1997, Pioneer advised mutual funds
with a total value of over $19.8 billion, which includes more than 1,000,000
U.S. shareholder accounts and other institutional accounts. Pioneer is a wholly
owned subsidiary of The Pioneer Group, Inc. ("PGI"). PGI, established in 1928,
is one of America's oldest investment managers and has its principal place of
business at 60 State Street, Boston, Massachusetts.
 
CAN I MAKE TRANSFERS AMONG THE INVESTMENT CHOICES?
 
Yes. Prior to the Annuity Date, you may transfer among the Sub-Accounts, the
Guarantee Period Accounts, and the Fixed Account. You will incur no current
taxes on transfers while your money remains in the Contract. See "D. Transfer
Privilege." The first 12 transfers in a Contract year are guaranteed to be free
of a transfer charge. For each subsequent transfer in a Contract year, the
Company does not currently charge, but reserves the right to assess a processing
charge guaranteed never to exceed $25.
 
WHAT IF I NEED MY MONEY BEFORE THE ANNUITY PAYOUT PHASE BEGINS?
 
You may surrender the Contract or make withdrawals any time before the annuity
payout phase begins. A 10% tax penalty may apply on all amounts deemed to be
income if you are under age 59 1/2. (A Market Value Adjustment, which may
increase or decrease the value of the account, may apply to any withdrawal made
from a Guarantee Period Account prior to the expiration of the Guarantee
Period.)
 
WHAT HAPPENS UPON MY DEATH DURING THE ACCUMULATION PHASE?
 
If you, a Joint Owner or (in the event that the Owner is a non-natural person)
an Annuitant should die prior to the Annuity Date, a death benefit will be paid
to the beneficiary. The standard death benefit will be equal to the greater of:
 
- - The Accumulated Value increased by any positive Market Value Adjustment; or
 
- -Gross payments, decreased proportionately to reflect withdrawals (for each
 withdrawal, the proportionate reduction is calculated as the death benefit
 under this option immediately prior to the withdrawal,
 
                                       9
<PAGE>
 multiplied by the withdrawal amount, and divided by the Accumulated Value
 immediately prior to the withdrawal).
 
An optional Enhanced Death Benefit Rider is available for a separate monthly
charge. See "G. Death Benefit" under "DESCRIPTION OF THE CONTRACT." Under the
Enhanced Death Benefit Rider:
 
I. If an Owner (or an Annuitant if the Owner is a non-natural person) dies prior
to the Annuity Date and before the oldest Owner's 90th birthday, the death
benefit will be equal to the greatest of:
 
(a) the Accumulated Value increased by any positive Market Value Adjustment (the
    "Accumulated Value"); or
 
(b) gross payments compounded daily at an annual rate of 5%, starting on the
    date each payment is applied, decreased proportionately to reflect
    withdrawals (5% compounding not available in Hawaii and New York); or
 
(c) the highest Accumulated Value of all Contract anniversaries, as determined
    after the Accumulated Value of each Contract anniversary is increased for
    subsequent payments and decreased proportionately for subsequent
    withdrawals.
 
The (c) value is determined on each Contract anniversary. A snapshot is taken of
the current (a) value and compared to snapshots taken of the (a) value on all
prior Contract anniversaries, AFTER all of the (a) values have been adjusted to
reflect subsequent payments and decreased proportionately for subsequent
withdrawals. The highest of all of these adjusted (a) values then becomes the
(c) value. This (c) value becomes the floor below which the death benefit will
not drop and is locked-in until the next Contract anniversary. The values of (b)
and (c) will be decreased proportionately if withdrawals are taken.
 
II. If an Owner (or an Annuitant if the Owner is a non-natural person) dies
prior to the Annuity Date but after the oldest Owner's 90th birthday, the death
benefit will be equal to the greater of:
 
(a) the Accumulated Value increased by any positive Market Value Adjustment; or
 
(b) the death benefit, as calculated under I, that would have been payable on
    the Contract anniversary immediately prior to the oldest Owner's 90th
    birthday, increased for subsequent payments and decreased proportionately
    for subsequent withdrawals.
 
WHAT CHARGES WILL I INCUR UNDER MY CONTRACT?
 
If the Accumulated Value on a Contract anniversary and upon surrender is less
than $75,000, the Company will deduct a $35 Contract fee from the Contract.
(This fee may vary by state. See your Contract for more information.)
 
A deduction for state and local premium taxes, if any, may be made as described
under "D. Premium Taxes."
 
The Company will deduct a daily Mortality and Expense Risk Charge and a daily
Administrative Expense Charge equal to an annual rate of 1.25% and 0.15%,
respectively, of the average daily net assets invested in each Underlying
Portfolio. The Portfolios will incur certain management fees and expenses which
are more fully described in "Other Charges" under "A. Variable Account
Deductions" and in the prospectus for the Fund, which accompanies this
Prospectus.
 
An optional rider (Enhanced Death Benefit Rider) is available for an additional
charge equal to an annual rate of 0.25% which is deducted on the last day of
each month and on the date the rider is terminated. For more information see "G.
Death Benefit" under "DESCRIPTION OF THE CONTRACT."
 
                                       10

For more information, see "CHARGES AND DEDUCTIONS."
 
CAN I EXAMINE THE CONTRACT?
 
Yes. The Contract will be delivered to you after your purchase. If you return
the Contract to the Company within ten days of receipt, the Contract will be
canceled. (There may be a longer period in certain states; see the "Right to
Examine" provision on the cover of the Contract.) If you cancel the Contract,
you will receive a refund of any amounts allocated to the Fixed and Guarantee
Period Accounts and the Accumulated Value of any amounts allocated to the
Sub-Accounts (plus any fees or charges that may have been deducted.) However, if
state law requires, or if the Contract was issued as an Individual Retirement
Annuity (IRA) you will generally receive a refund of your entire payment. (In
certain states this refund may be the greater of (1) your entire payment or (2)
the amounts allocated to the Fixed and Guarantee Period Accounts plus the
Accumulated Value of amounts in the Sub-Accounts, plus any fees or charges
previously deducted.) See "B. Right to Cancel Individual Retirement Annuity" and
"C. Right to Cancel All Other Contracts."

guarantees that the first 12 transfers in a Contract year will not be
subject to a transfer charge. For each subsequent transfer, the
Company reserves the right to assess a charge, guaranteed never to
exceed $25, to reimburse the Company for the costs of processing the
transfer.

</TABLE>
 
(1)The Growth Shares and Growth and Income Portfolios commenced operations on
October 31, 1997 and the Emerging Markets and Europe Portfolios commenced
operations on October 30, 1998; therefore expenses shown are estimated and
annualized after expense reimbursements and should not be considered
representative of future expenses. Actual expenses may be greater than shown.
 
(2) Total expenses are net of amounts paid in connection with certain expense 
offset arrangements. Assuming no reduction for expense offset arrangements 
(but including fee waivers noted in footnote 3 below), total operating 
expenses for fiscal year ended December 31, 1997, would have been 1.49% for 
International Growth Portfolio, 0.80% for Capital Growth Portfolio, 1.25% for 
Real Estate Growth Portfolio, 0.96% for Balanced Portfolio, 1.23% for Swiss 
Franc Bond Portfolio, 1.26% for America Income Portfolio and 1.00% for Money 
Market Portfolio. No offset arrangements affected Growth Shares Portfolio, 
Growth and Income Portfolio and Equity-Income Portfolio.
 
(3) No waiver of management fees or reimbursement of other expenses affected
Capital Growth Portfolio, Equity-Income Portfolio and Balanced Portfolio. For
the fiscal year ended December 31, 1997, assuming no waiver of management fees
and no expense offset arrangements, Portfolio expenses as a percentage of the
average daily net assets were 1.71% for International Growth Portfolio, 0.80%
for Capital Growth Portfolio, 6.57% for Growth Shares Portfolio, 1.37% for Real
Estate Growth Portfolio, 5.30% for Growth and Income Portfolio, 0.96% for
Balanced Portfolio, 1.25% for Swiss Franc Bond Portfolio; 1.43% for America
Income Portfolio and 1.17% for Money Market Portfolio.
 
Pioneer Investment Management, Inc. ("Pioneer") is the investment adviser to
each Portfolio. As of the date of this prospectus, Pioneer has agreed
voluntarily to limit its management fee and/or reimburse each Portfolio for
expenses to the extent that total expenses will not exceed 1.75% for the
Emerging Markets Portfolio; 1.50% for the International Growth Portfolio; 1.50%
for the Europe Portfolio; 1.25% for the Growth Shares Portfolio, the Real Estate
Growth Portfolio, the Growth and Income Portfolio, the Swiss Franc Bond
Portfolio and the America Income Portfolio and 1.00% for the Money Market
Portfolio. The declaration of a voluntary limitation and/or reimbursement in any
year does not bind the Manager to declare future expense limitations with
respect to these funds. These limitations/waivers may be terminated at any time
with notice.

Pursuant to requirements of the SEC, the Contract fee has been reflected in the
examples by a method intended to show the "average" impact of the Contract fee
on an investment in the Variable Account. The total Contract fees collected by
the Company under the Contracts are divided by the total average net assets
attributable to the Contracts. The resulting percentage is 0.04%, and the amount
of the Contract fee is assumed to be $0.40 in the examples. The Contract fee is
deducted only when the accumulated value is less than $75,000.
 
The Contract fee is not deducted after annuitization.

No information is available for the Sub-Accounts investing in the Emerging
Markets and Europe Portfolios, as the Sub-Accounts did not commence operations
until October 30, 1998.
 
                            PERFORMANCE INFORMATION
 
The Pioneer C-Vision Contract was first offered to the public in 1999. The
Company, however, may advertise "total return" and "average annual total return"
performance information based on the periods that the Sub-Accounts have been in
existence and the periods that the Underlying Portfolios have been in existence.
Performance results for all periods shown below will be calculated with all
charges assumed to be those applicable to the Sub-Accounts and the Underlying
Portfolios. Both the total return and yield figures are based on historical
earnings and are not intended to indicate future performance.
 
The total return of a Sub-Account refers to the total of the income generated by
an investment in the Sub-Account and of the changes in the value of the
principal (due to realized and unrealized capital gains or losses) for a
specified period, reduced by Variable Account charges, and expressed as a
percentage.
 
The average annual total return represents the average annual percentage change
in the value of an investment in the Sub-Account over a given period of time. It
represents averaged figures as opposed to the actual performance of a
Sub-Account, which will vary from year to year.
 
The yield of the Sub-Account investing in the Money Market Portfolio refers to
the income generated by an investment in the Sub-Account over a seven-day period
(which period will be specified in the advertisement). This income is then
"annualized" by assuming that the income generated in the specific week is
generated over a 52-week period. This annualized yield is shown as a percentage
of the investment. The "effective yield" calculation is similar but, when
annualized, the income earned by an investment in the Sub-Account is assumed to
be reinvested. Thus the effective yield will be slightly higher than the yield
because of the compounding effect of this assumed reinvestment.
 
The yield of a Sub-Account investing in a Portfolio other than the Money Market
Portfolio refers to the annualized income generated by an investment in the
Sub-Account over a specified 30-day or one-month period. The yield is calculated
by assuming that the income generated by the investment during that 30-day or
one-month period is generated each period over a 12-month period and is shown as
a percentage of the investment.
 
Quotations of average annual total return as shown in Tables 1A and 1B are
calculated in the manner prescribed by the SEC and show the percentage rate of
return of a hypothetical initial investment of $1,000 for the most recent one,
five and ten year period or for a period covering the time the Sub-Account has
been in existence, if less than the prescribed periods. The calculation is
adjusted to reflect the deduction of the annual Sub-Account asset charge of
1.40%, the annual Contract fee and Underlying Portfolio charges. The calculation
is not adjusted to reflect the deduction of the optional Enhanced Death Benefit
Rider charge of 0.25% which, if elected, would reduce performance.
 
The performance shown in Table 2A is calculated in exactly the same manner as
those in Tables 1A and 1B; however, the period of time is based on the
Underlying Portfolios' lifetime, which may predate the Sub-
 
                                       17
<PAGE>
Accounts' inception dates. These performance calculations are based on the
assumption that the Sub-Account corresponding to the applicable Underlying
Portfolio was actually in existence throughout the stated period and that the
contractual charges and expenses during that period were equal to those
currently assessed under the Contract.
 
For more detailed information about these performance calculations, including
actual formulas, see the SAI.
 
PERFORMANCE INFORMATION FOR ANY SUB-ACCOUNT REFLECTS ONLY THE PERFORMANCE OF A
HYPOTHETICAL INVESTMENT IN THE SUB-ACCOUNT DURING THE TIME PERIOD ON WHICH THE
CALCULATIONS ARE BASED. PERFORMANCE INFORMATION SHOULD BE CONSIDERED IN LIGHT OF
THE INVESTMENT OBJECTIVES AND POLICIES AND RISK CHARACTERISTICS OF THE
UNDERLYING PORTFOLIO IN WHICH THE SUB-ACCOUNT INVESTS AND THE MARKET CONDITIONS
DURING THE GIVEN TIME PERIOD, AND SHOULD NOT BE CONSIDERED AS A REPRESENTATION
OF WHAT MAY BE ACHIEVED IN THE FUTURE.
 
Performance information for a Sub-Account may be compared, in reports and
promotional literature, to: (1) the Standard & Poor's 500 Composite Stock Price
Index ("S&P 500"), Dow Jones Industrial Average ("DJIA"), Shearson Lehman
Aggregate Bond Index or other unmanaged indices so that investors may compare
the Sub-Account results with those of a group of unmanaged securities widely
regarded by investors as representative of the securities markets in general;
(2) other groups of variable annuity separate accounts or other investment
products tracked by Lipper Analytical Services, a widely used independent
research firm which ranks mutual funds and other investment products by overall
performance, investment objectives, and assets, or tracked by other services,
companies, publications, or persons, who rank such investment products on
overall performance or other criteria; or (3) the Consumer Price Index (a
measure for inflation) to assess the real rate of return from an investment in
the Sub-Account. Unmanaged indices may assume the reinvestment of dividends but
generally do not reflect deductions for administrative and management costs and
expenses.
 
At times, the Company may also advertise the ratings and other information
assigned to it by independent rating organizations such as A.M. Best Company
("A.M. Best"), Moody's Investors Service ("Moody's"), Standard & Poor's
Insurance Rating Services ("S&P") and Duff & Phelps. A.M. Best's and Moody's
ratings reflect their current opinion of the Company's relative financial
strength and operating performance in comparison to the norms of the life/health
insurance industry. S&P's and Duff & Phelps' ratings measure the ability of an
insurance company to meet its obligations under insurance policies it issues and
do not measure the ability of such companies to meet other non-policy
obligations. The ratings also do not relate to the performance of the Underlying
Portfolios.

1994. The Variable Accounts meet the definition of "separate account" under
federal securities laws, and are registered with the SEC as unit investment
trusts under the Investment Company Act of 1940 ("1940 Act"). Such registration
does not involve the supervision of management or investment practices or
policies of the Variable Accounts by the SEC.
 
Each Company may offer other variable annuity contracts investing in the
Variable Accounts which are not discussed in this Prospectus. The Variable
Accounts also may invest in other underlying funds which are not available to
the Contracts described in this Prospectus. Each Company reserves the right,
subject to compliance with applicable law, to change the names of the Variable
Accounts and the Sub-Accounts.
 
PIONEER VARIABLE CONTRACTS TRUST
 
Pioneer Variable Contracts Trust (the "Fund") is an open-end, management
investment company registered with the SEC under the 1940 Act. Such registration
does not involve supervision by the SEC of the investments or investment policy
of the Fund or its separate investment Portfolios. Pioneer Investment
Management, Inc. ("Pioneer") is the investment adviser to each Portfolio.
 
The Fund was established to provide a vehicle for the investment of assets of
various separate accounts supporting variable insurance policies. The Fund
currently has twelve investment portfolios ("Underlying Portfolios"), each
issuing a separate series of shares: Emerging Markets Portfolio, International
Growth Portfolio, Europe Portfolio, Capital Growth Portfolio, Growth Shares
Portfolio, Real Estate Growth Portfolio, Growth and Income Portfolio,
Equity-Income Portfolio, Balanced Portfolio, Swiss Franc Bond Portfolio, America
Income Portfolio and Money Market Portfolio. The assets of each Portfolio are
held separately from the assets of the other Portfolios. Each Portfolio operates
as a separate investment vehicle, and the income or losses of one Portfolio have
no effect on the investment performance of another Portfolio. Shares of the Fund
may be sold directly to separate accounts established and maintained by
insurance companies for the purpose of funding variable contracts and to certain
qualified pension and retirement plans.

                          DESCRIPTION OF THE CONTRACT
 
Unless otherwise specified, any reference to the "Company" in this Prospectus
shall refer exclusively to Allmerica Financial Life Insurance and Annuity
Company for contracts issued in the District of Columbia, Puerto Rico, the
Virgin Islands and any state except Hawaii and New York and exclusively to First
Allmerica Financial Life Insurance Company for contracts issued in Hawaii and
New York.
 
A. PAYMENTS
 
The Company's underwriting requirements, which include receipt of the initial
payment and allocation instructions by the Company at its Principal Office, must
be met before a Contract can be issued. These requirements also may include the
proper completion of an application; however, where permitted, the Company may
issue a Contract without completion of an application and/or signature for
certain classes of Contracts. Payments are to be made payable to the Company. A
net payment is equal to the payment received less the amount of any applicable
premium tax.
 
The initial net payment will be credited to the Contract and allocated among the
requested accounts as of the date that all issue requirements are properly met.
If all issue requirements are not complied with within five business days of the
Company's receipt of the initial payment, the payment will be returned unless
the Owner specifically consents to the holding of the initial payment until
completion of any outstanding issue requirements. Subsequent payments will be
credited as of the Valuation Date received at the Principal Office on the basis
of accumulation unit value next determined after receipt.
 
Payments are not limited as to frequency and number, but there are certain
limitations as to amount. Currently, the initial payment must be at least
$25,000. Each subsequent payment must be at least $100. The minimum allocation
to a Guarantee Period Account is $1,000. If less than $1,000 is allocated to a
Guarantee Period Account, the Company reserves the right to apply that amount to
the Money Market Portfolio.
 
From time to time where permitted by law, the Company may credit amounts to
Contracts, when Contracts are sold to individuals or groups of individuals in a
manner that reduces sales expenses. The Company will consider factors such as
the following: (1) the size and type of group or class, and the persistency
expected
 
                                       23
<PAGE>
from that group or class; (2) the total amount of payments to be received, and
the manner in which payments are remitted; (3) the purpose for which the
Contracts are being purchased, and whether that purpose makes it likely that
costs and expenses will be reduced; (4) other transactions where sales expenses
are likely to be reduced; or (5) the level of commissions paid to selling
broker-dealers or certain financial institutions with respect to Contracts
within the same group or class (for example, broker-dealers who offer the
Contract in connection with financial planning services offered on a
fee-for-service basis). The Company may also credit amounts to Contracts, where
either the Owner or the Annuitant on the date of issue is within the following
classes of individuals ("eligible persons"): employees and registered
representatives of any broker-dealer which has entered into a sales agreement
with the Company to sell the Contract; employees of the Company, its affiliates
and subsidiaries; officers, directors, trustees and employees of any of the
Underlying Portfolios, investment managers or Sub-Advisers; and the spouses of
and immediate family members residing in the same household with such eligible
persons. "Immediate family members" means children, siblings, parents and
grandparents.
 
Generally, unless otherwise requested, all payments will be allocated among the
accounts in the same proportion that the initial net payment is allocated or, if
subsequently changed, according to the most recent allocation instructions. The
Owner may change allocation instructions for new payments pursuant to a written
or telephone request. If telephone requests are elected by the Owner, a properly
completed authorization must be on file before telephone requests will be
honored. The policy of the Company and its agents and affiliates is that they
will not be responsible for losses resulting from acting upon telephone requests
reasonably believed to be genuine. The Company will employ reasonable procedures
to confirm that instructions communicated by telephone are genuine; otherwise,
the Company may be liable for any losses due to unauthorized or fraudulent
instructions. The procedures the Company follows for transactions initiated by
telephone include requirements that callers on behalf of an Owner identify
themselves by name and identify the Annuitant by name, date of birth and social
security number. All transfer instructions by telephone are tape-recorded.
 
B. RIGHT TO CANCEL INDIVIDUAL RETIREMENT ANNUITY
 
An individual purchasing a Contract intended to qualify as an IRA may cancel the
Contract at any time within ten days after receipt of the Contract and receive a
refund. In order to cancel the Contract, the Owner must mail or deliver the
Contract to the agent through whom the Contract was purchased, to the Company's
Principal Office at 440 Lincoln Street, Worcester, MA 01653, or to an authorized
representative. Mailing or delivery must occur within ten days after receipt of
the Contract for cancellation to be effective.
 
Within seven days, the Company will provide a refund equal to gross payment(s)
received. In some states, however, the refund may equal the greater of (a) gross
payments or (b) the amounts allocated to the Fixed and Guaranteed Period
Accounts plus the Accumulated Value of amounts in the Sub-Accounts plus any
amounts deducted under the Contract or by the Underlying Portfolios for taxes,
charges or fees. At the time the Contract is issued the "Right to Examine"
provision on the cover of the Contract will specifically indicate whether the
refund will be equal to gross payments or equal to the greater of (a) or (b) as
set forth above.
 
The liability of the Variable Account under this provision is limited to the
Owner's Accumulated Value in the Sub-Accounts on the date of cancellation. Any
additional amounts refunded to the Owner will be paid by the Company.
 
C. RIGHT TO CANCEL ALL OTHER CONTRACTS
 
An Owner may cancel the Contract at any time within ten days after receipt of
the Contract (or longer if required by state law) and receive a refund.
Generally, the Company will pay to the Owner an amount equal to the sum of (1)
the difference between the amount paid, including fees, and any amount allocated
to the Variable Account, and (2) the Accumulated Value of amounts allocated to
the Variable Account as of the date the request is received. If the Contract was
purchased as an IRA or issued in a state that requires a full refund of the
initial payment(s), the IRA cancellation right described above may be utilized
in lieu of the special
 
                                       24
<PAGE>
surrender right. At the time the Contract is issued, the "Right to Examine"
provision on the cover of the Contract will specifically indicate what the
refund will be and the time period allowed to exercise the right to cancel.
 
D. TRANSFER PRIVILEGE
 
Prior to the Annuity Date, the Owner may transfer amounts among accounts at any
time upon written or telephone request to the Company. As discussed in "A.
Payments," a properly completed authorization form must be on file before
telephone requests will be honored. Transfer values will be based on the
Accumulated Value next computed after receipt of the transfer request.
 
Transfers to a Guarantee Period Account must be at least $1,000. If the amount
to be transferred to a Guarantee Period Account is less than $1,000, the Company
may transfer that amount to the Money Market Portfolio. Transfers from a
Guarantee Period Account prior to the expiration of the Guarantee Period will be
subject to a Market Value Adjustment.
 
Currently, the Company makes no charge for transfers. The first twelve transfers
in a Contract year are guaranteed to be free of any transfer charge. For each
subsequent transfer in a Contract year, the Company does not currently charge
but reserves the right to assess a charge, guaranteed never to exceed $25, to
reimburse it for the expense of processing transfers.
 
The Owner may authorize an independent third party to transact allocations and
transfers in accordance with an asset allocation strategy or other investment
strategy. The Company may provide administrative or other support services to
these independent third parties, however, the Company does not engage any third
parties to offer allocation or other investment services under this Contract,
does not endorse or review any allocation or transfer recommendations and is not
responsible for the investment results of such allocations or transfers
transacted on the Owner's behalf. In addition, the Company reserves the right to
discontinue services or limit the number of Portfolios that it may provide such
services for, as well as to restrict such transactions altogether when exercised
by a market timing firm or any other third party authorized to initiate
allocations, transfers or exchanges on behalf of multiple Contract owners. The
Company does not charge the Owner for providing additional support services.
 
As indicated above, the Company also reserves the right to restrict transfer
privileges when exercised by a market timing firm or any other third party
authorized to initiate allocations, transfers or exchanges on behalf of multiple
Contract owners, if the execution of such transactions may disadvantage or
potentially impair the Contract rights of other Contract owners. The Company
may, among other things, not accept (1) the transfer or exchange instructions of
any agent acting under a power of attorney on behalf of more than one Contract
owner, or (2) the transfer or exchange instructions of individual Contract
owners who have executed pre-authorized transfer or exchange forms which are
submitted by market timing firms or other third parties on behalf of more than
one Contract owner at the same time.
 
AUTOMATIC TRANSFERS (DOLLAR COST AVERAGING) AND AUTOMATIC ACCOUNT REBALANCING
OPTIONS. The Owner may elect automatic transfers of a predetermined dollar
amount, not less than $100, on a periodic basis (monthly, bi-monthly, quarterly,
semi-annually or annually) from the Money Market Portfolio, the America Income
Portfolio or the Fixed Account (the source account) to one or more Portfolios.
Automatic transfers may not be made into the Fixed Account, the Guarantee Period
Accounts or, if applicable, the Portfolio being used as the source account. If
an automatic transfer would reduce the balance in the source account to less
than $100, the entire balance will be transferred proportionately to the chosen
Portfolios. Automatic transfers will continue until the amount in the source
account on a transfer date is zero or the Owner's request to terminate the
option is received by the Company. If additional amounts are allocated to the
source account after its balance has fallen to zero, this option will not
restart automatically and the Owner must provide a new request to the Company.
 
                                       25
<PAGE>
To the extent permitted by state law, the Company reserves the right, from time
to time, to credit an enhanced interest rate to certain initial and/or
subsequent payments which are deposited into the Fixed Account and which utilize
the Fixed Account as the source account for the payment from which to process
automatic transfers. For more information see APPENDIX A, "MORE INFORMATION
ABOUT THE FIXED ACCOUNT."
 
The Owner may request automatic rebalancing of Sub-Account allocations on a
monthly, bi-monthly, quarterly, semi-annual or annual basis in accordance with
specified percentage allocations. As frequently as requested, the Company will
review the percentage allocations in the Portfolios and, if necessary, transfer
amounts to ensure conformity with the designated percentage allocation mix. If
the amount necessary to re-establish the mix on any scheduled date is less than
$100, no transfer will be made. Automatic Account Rebalancing will continue
until the Owner's request to terminate or change the option is received by the
Company. As such, subsequent payments allocated in a manner different from the
percentage allocation mix in effect on the date the payment is received will be
reallocated in accordance with the existing mix on the next scheduled date
unless the Owner's timely request to change the mix or terminate the option is
received by the Company.
 
The Company reserves the right to limit the number of Portfolios that may be
utilized for automatic transfers and rebalancing, and to discontinue either
option upon advance written notice. The first automatic transfer or rebalancing
and all subsequent transfers or rebalancing of that request in the same Contract
Year count as one transfer towards the 12 transfers which are guaranteed to be
free of a transfer charge in each Contract Year. There currently is no charge
for either program. Currently, Dollar Cost Averaging and Automatic Account
Rebalancing may not be in effect simultaneously. Either option may be elected
when the Contract is purchased or at a later date.
 
E. SURRENDER
 
At any time prior to the Annuity Date, an Owner may surrender the Contract and
receive an amount equal to the Surrender Value less any applicable tax
withholding. The Owner must return the Contract and a signed, written request
for surrender, satisfactory to the Company, to the Principal Office. The amount
payable to the Owner upon surrender will be based on the Contract's Accumulated
Value as of the Valuation Date on which the request and the Contract are
received at the Principal Office. The Contract fee will be deducted upon
surrender of the Contract.
 
After the Annuity Date, only a Contract under which a commutable period certain
option has been elected may be surrendered. The Surrender Amount is the commuted
value of any unpaid installments, computed on the basis of the assumed interest
rate incorporated in such annuity benefit payments.
 
Any amount surrendered normally is payable within seven days following the
Company's receipt of the surrender request. The Company reserves the right to
defer surrenders and withdrawals of amounts in each Sub-Account in any period
during which (1) trading on the New York Stock Exchange is restricted as
determined by the SEC or such Exchange is closed for other than weekends and
holidays, (2) the SEC has, by order, permitted such suspension, or (3) an
emergency, as determined by the SEC, exists such that disposal of portfolio
securities or valuation of assets of a separate account is not reasonably
practicable.
 
The Company reserves the right to defer surrenders and withdrawals of amounts
allocated to the Company's Fixed Account and Guarantee Period Accounts for a
period not to exceed six months.
 
                                       26
<PAGE>
The surrender rights of Owners who are participants under Section 403(b) plans
or who are participants in the Texas Optional Retirement Program ("Texas ORP")
are restricted; see "Tax-Sheltered Annuities" and "Texas Optional Retirement
Program."
 
Where an Owner who is trustee under a pension plan surrenders, in whole or in
part, a Contract on a terminating employee, the trustee will be permitted to
reallocate all or a part of the Accumulated Value under the Contract to other
contracts issued by the Company and owned by the trustee. Any such reallocation
will be at the Accumulation Unit values for the Sub-Accounts as of the Valuation
Date on which a written, signed request is received at the Principal Office.
 
For important tax consequences which may result from surrender, see "FEDERAL TAX
CONSIDERATIONS."
 
F. WITHDRAWALS
 
At any time prior to the Annuity Date, the Owner may withdraw a portion of the
Accumulated Value of his or her Contract, subject to the limits stated below.
The Owner must submit to the Principal Office a signed, written request for
withdrawal, satisfactory to the Company. The written request must indicate the
dollar amount the Owner wishes to receive and the accounts from which such
amount is to be withdrawn. Amounts withdrawn from a Guarantee Period Account
prior to the end of the applicable Guarantee Period will be subject to a Market
Value Adjustment against the remaining value, as described under "GUARANTEE
PERIOD ACCOUNTS."
 
Where allocations have been made to more than one account, a percentage of the
withdrawal may be allocated to each such account. A withdrawal from a
Sub-Account will result in cancellation of a number of units equivalent in value
to the amount withdrawn, computed as of the Valuation Date that the request is
received at the Principal Office.
 
Each withdrawal must be in a minimum amount of $100. No withdrawal will be
permitted if the Accumulated Value remaining under the Contract would be reduced
to less than $1,000. Withdrawals will be paid in accordance with the time
limitations described under "E. Surrender."
 
For important restrictions on withdrawals which are applicable to Owners who are
participants under Section 403(b) plans or under the Texas ORP, see "FEDERAL TAX
CONSIDERATIONS," "Tax-Sheltered Annuities" and "Texas Optional Retirement
Program." For important tax consequences which may result from withdrawals, see
"FEDERAL TAX CONSIDERATIONS."
 
SYSTEMATIC WITHDRAWALS.  The Owner may elect an automatic schedule of
withdrawals (systematic withdrawals) from amounts in the Sub-Accounts and/or the
Fixed Account on a monthly, bi-monthly, quarterly, semi-annual or annual basis.
Systematic withdrawals from Guarantee Period Accounts are not available. The
minimum amount of each automatic withdrawal is $100. If elected at the time of
purchase, the Owner must designate in writing the specific dollar amount of each
withdrawal and the percentage of this amount which should be taken from each
designated Sub-Account and/or the Fixed Account. Systematic withdrawals then
will begin on the date indicated on the application. If elected after the issue
date, the Owner may elect, by written request, a specific dollar amount and the
percentage of this amount to be taken from each designated Sub-Account and/or
the Fixed Account, or the Owner may elect to withdraw a specific percentage of
the Accumulated Value calculated as of the withdrawal dates, and may designate
the percentage of this amount which should be taken from each account. The first
withdrawal will take place on the date the written request is received at the
Principal Office or, if later, on a date specified by the Owner.
 
If a withdrawal would cause the remaining Accumulated Value to be less than
$1,000, systematic withdrawals will be discontinued. Systematic withdrawals will
cease automatically on the Annuity Date. The Owner may change or terminate
systematic withdrawals only by written request to the Principal Office.
 
                                       27
<PAGE>
LIFE EXPECTANCY DISTRIBUTIONS.  Prior to the Annuity Date the Owner who also is
the Annuitant may elect to make a series of systematic withdrawals from the
Contract according to a life expectancy distribution ("LED") option by returning
a properly signed LED request form to the Principal Office. The LED option
permits the Owner to make systematic withdrawals from the Contract over his or
her lifetime. The amount withdrawn from the Contract changes each year, because
life expectancy changes each year that a person lives. For example, actuarial
tables indicate that a person age 70 has a life expectancy of 16 years, but a
person who attains age 86 has a life expectancy of another 6.5 years. While an
LED is in effect, the Owner must remain the Annuitant.
 
If an Owner elects the LED option, in each calendar year a fraction of the
Accumulated Value is withdrawn based on the Owner's then life expectancy. The
numerator of the fraction is 1 (one), and the denominator of the fraction is the
remaining life expectancy of the Owner, as determined annually by the Company.
The resulting fraction, expressed as a percentage, is applied to the Accumulated
Value at the beginning of the year to determine the amount to be distributed
during the year. The Owner may elect monthly, bi-monthly, quarterly,
semi-annual, or annual distributions, and may terminate the LED option at any
time. Under contracts issued in Hawaii and New York, the LED option will
terminate automatically on the maximum Annuity Date permitted under the Contract
at which time an Annuity Option must be elected. The Owner also may elect to
receive distributions under an LED option which is determined on the joint life
expectancy of the Owner and a beneficiary. The Company also may offer other
systematic withdrawal options.
 
Where the Owner is a trust or other non-natural person, the Owner may elect the
LED option based on the Annuitant's life expectancy.
 
If an Owner makes withdrawals under the LED option prior to age 59 1/2, the
withdrawals may be treated by the Internal Revenue Service ("IRS") as premature
distributions from the Contract. The payments then would be taxed on an "income
first" basis and be subject to a 10% federal tax penalty. For more information,
see "FEDERAL TAX CONSIDERATIONS" and "B. Taxation of the Contracts in General."
 
The Company may discontinue or change the LED option at any time, but not with
respect to election of the option made prior to the date of any change in the
LED option.
 
G. DEATH BENEFIT
 
In the event that an Owner or (in the event the Owner is a non-natural person)
an Annuitant dies prior to the Annuity Date, the Company will pay the
beneficiary a death benefit, except where the Contract is continued as provided
in "H. The Spouse of the Owner as Beneficiary."
 
DEATH OF AN OWNER PRIOR TO THE ANNUITY DATE.  Upon the death of an Owner (or an
Annuitant if the Owner is a non-natural person), a death benefit will be paid.
The standard death benefit will be equal to the greater of (a) the Accumulated
Value under the Contract increased by any positive Market Value Adjustment; or
(b) gross payments, decreased proportionately to reflect withdrawals (for each
withdrawal, the proportionate reduction is calculated as the death benefit under
this option immediately prior to the withdrawal multiplied by the withdrawal
amount and divided by the Accumulated Value immediately prior to the
withdrawal).
 
                                       28
<PAGE>
OPTIONAL ENHANCED DEATH BENEFIT RIDER.  At the time of application for the
Contract, the Owner may elect an optional Enhanced Death Benefit Rider. Under
the Enhanced Death Benefit Rider:
 
I. If an Owner (or an Annuitant if the Owner is a non-natural person) dies prior
to the Annuity Date and before the oldest Owner's 90th birthday, the death
benefit will be equal to the greatest of:
 
(a) the Accumulated Value increased by any positive Market Value Adjustment (the
    "Accumulated Value"); or
 
(b) gross payments compounded daily at an annual rate of 5%, starting on the
    date each payment is applied, decreased proportionately to reflect
    withdrawals (5% compounding not available in Hawaii and New York); or
 
(c) the highest Accumulated Value of all Contract anniversaries, as determined
    after the Accumulated Value of each Contract anniversary is increased for
    subsequent payments and decreased proportionately for subsequent
    withdrawals.
 
The (c) value is determined on each Contract anniversary. A snapshot is taken of
the current (a) value and compared to snapshots taken of the (a) value on all
prior Contract anniversaries, after all of the (a) values have been adjusted to
reflect subsequent payments and decreased proportionately for subsequent
withdrawals. The highest of all of these adjusted (a) values then becomes the
(c) value. This (c) value becomes the floor below which the death benefit will
not drop and is locked-in until the next Contract anniversary. The values of (b)
and (c) will be decreased proportionately if withdrawals are taken.
 
II. If an Owner (or an Annuitant if the Owner is a non-natural person) dies
prior to the Annuity Date but after the oldest Owner's 90th birthday, the death
benefit will be equal to the greater of:
 
(a) the Accumulated Value increased by any positive Market Value Adjustment; or
 
(b) the death benefit, as calculated under I, that would have been payable on
    the Contract anniversary immediately prior to the oldest Owner's 90th
    birthday, increased for subsequent payments and decreased proportionately
    for subsequent withdrawals.
 
A separate charge is made for an optional Enhanced Death Benefit Rider. On the
last day of each month and on the date the Rider is terminated, a charge equal
to 1/12th of an annual rate of 0.25% is made against the Accumulated Value of
the Contract at that time. The charge is deducted in arrears through a pro-rata
reduction (based on relative values) of Accumulation Units in the Sub-Accounts,
of dollar amounts in the Fixed Account, and of dollar amounts in the Guarantee
Period Accounts.
 
PAYMENT OF THE DEATH BENEFIT.  The death benefit generally will be paid to the
beneficiary in one sum within seven business days of the receipt of due proof of
death at the Principal Office unless the Owner has specified a death benefit
annuity option. Instead of payment in one sum, the beneficiary may, by written
request, elect to:
 
(1) defer distribution of the death benefit for a period no more than five years
    from the date of death; or
 
(2) receive a life annuity or an annuity for a period certain not extending
    beyond the beneficiary's life expectancy, with annuity benefit payments
    beginning one year from the date of death.
 
If distribution of the death benefit is deferred under (1) or (2), any value in
the Guarantee Period Accounts will be transferred to the Sub-Account investing
in the Money Market Portfolio. The excess, if any, of the death benefit over the
Accumulated Value also will be transferred to the Sub-Account investing in the
Money Market Portfolio. The beneficiary may, by written request, effect
transfers and withdrawals during the deferral period and prior to annuitization
under (2), but may not make additional payments. The death benefit will reflect
any earnings or losses experienced during the deferral period. If there are
multiple beneficiaries, the consent of all is required.
 
                                       29
<PAGE>
With respect to the death benefit, the Accumulated Value under the Contract will
be based on the unit values next computed after receipt of due proof of death.
 
H. THE SPOUSE OF THE OWNER AS BENEFICIARY
 
The Owner's spouse, if named as the sole beneficiary, may by written request
continue the Contract in lieu of receiving the amount payable upon death of the
Owner. Upon such election, the spouse will then become the Owner and Annuitant
subject to the following: (1) any value in the Guarantee Period Accounts will be
transferred to the Sub-Account investing in the Money Market Portfolio and (2)
the excess, if any, of the death benefit over the Contract's Accumulated Value
also will be added to the Sub-Account investing in the Money Market Portfolio.
Additional payments may be made. All other rights and benefits provided in the
Contract will continue, except that any subsequent spouse of such new Owner will
not be entitled to continue the Contract upon such new Owner's death.
 
I. ASSIGNMENT
 
The Contract, other than those sold in connection with certain qualified plans,
may be assigned by the Owner at any time prior to the Annuity Date and prior to
the death of an Owner (see "FEDERAL TAX CONSIDERATIONS"). The Company will not
be deemed to have knowledge of an assignment unless it is made in writing and
filed at the Principal Office. The Company will not assume responsibility for
determining the validity of any assignment. If an assignment of the Contract is
in effect on the Annuity Date, the Company reserves the right to pay to the
assignee, in one sum, that portion of the Surrender Value of the Contract to
which the assignee appears to be entitled. The Company will pay the balance, if
any, in one sum to the Owner in full settlement of all liability under the
Contract. The interest of the Owner and of any beneficiary will be subject to
any assignment.
 
J. ELECTING THE FORM OF ANNUITY AND THE ANNUITY DATE
 
The Annuity Date is selected by the Owner. To the extent permitted by state law,
the Annuity Date may be the first day of any month (1) before the Owner's 85th
birthday, if the Owner's age on the issue date of the Contract is 75 or under;
or (2) within ten years from the issue date of the Contract and before the
Owner's 90th birthday, if the Owner's age on the issue date is between 76 and
90. The Owner may elect to change the Annuity Date by sending a request to the
Principal Office at least one month before the Annuity Date. To the extent
permitted by state law, the new Annuity Date must be the first day of any month
occurring before the Owner's 99th birthday. If there are Joint Owners, the age
of the younger will determine the Annuity Date. The Internal Revenue Code (the
"Code") and the terms of qualified plans impose limitations on the age at which
annuity benefit payments may commence and the type of annuity option selected.
See "FEDERAL TAX CONSIDERATIONS" for further information.
 
Subject to certain restrictions described below, the Owner has the right (1) to
select the annuity option under which annuity benefit payments are to be made,
and (2) to determine whether payments are to be made on a fixed basis, a
variable basis, or a combination fixed and variable basis. Annuity benefit
payments are determined according to the annuity tables in the Contract, by the
annuity option selected, and by the investment performance of the accounts
selected.
 
To the extent a fixed annuity payout is selected, Accumulated Value will be
transferred to the Fixed Account of the Company, and the annuity benefit
payments will be fixed in amount. See APPENDIX A, "MORE INFORMATION ABOUT THE
FIXED ACCOUNT."
 
Under a variable annuity payout, a payment to the Owner, or the payee the Owner
designates, equal to the value of the fixed number of Annuity Units in the
Sub-Accounts is made monthly, quarterly, semi-annually or annually. Since the
value of an Annuity Unit in a Sub-Account will reflect the investment
performance of the Sub-Account, the amount of each annuity benefit payment will
vary.
 
                                       30
<PAGE>
The annuity option(s) selected must produce an initial payment of at least $50
(a lower amount may be required in some states). The Company reserves the right
to increase this minimum amount. If the annuity option(s) selected do(es) not
produce an initial payment which meets this minimum, a single payment may be
made. Once the Company begins making annuity benefit payments, the Owner cannot
make withdrawals or surrender the annuity benefit, except where the Owner has
elected a commutable period certain option. Beneficiaries entitled to receive
remaining payments under either a commutable or non-commutable "period certain"
option may elect instead to receive a lump sum settlement. See "K. Description
of Variable Annuity Payout Options."
 
If the Owner does not elect otherwise, a variable life annuity with periodic
payments for ten years guaranteed will be purchased. Changes in either the
Annuity Date or annuity option can be made up to one month prior to the Annuity
Date.
 
If an Owner of a fixed annuity contract issued by the Company wishes to elect a
variable annuity option, the Company may permit such Owner to exchange, at the
time of annuitization, the fixed contract for a Contract offered in this
Prospectus. The proceeds of the fixed contract will be applied towards the
variable annuity option desired by the Owner. The number of Annuity Units under
the option will be calculated using the Annuity Unit values as of the 15th of
the month preceding the Annuity Date.
 
K. DESCRIPTION OF VARIABLE ANNUITY PAYOUT OPTIONS
 
The Company provides the variable annuity payout options described below.
Currently, variable annuity payout options may be funded through the
Sub-Accounts investing in the Capital Growth Portfolio, the Equity-Income
Portfolio and the America Income Portfolio. The Company also provides these same
options funded through the Fixed Account (fixed annuity payout). Regardless of
how payments were allocated during the accumulation period, any of the variable
payout options or the fixed payout options may be selected, or any of the
variable options may be selected in combination with any of the fixed options.
Other annuity options may be offered by the Company. IRS regulations may not
permit certain of the available annuity payout options when used in connection
with certain qualified Contracts.
 
If the Owner (or, if there are Joint Owners, the surviving Joint Owner) dies on
or after the Annuity Date, the beneficiary will become the Owner of the contract
and receive any remaining annuity benefit payments in accordance with the terms
of the annuity benefit payment option selected prior to the Annuity Date. If
there are Joint Owners on or after the Annuity Date, upon the first Owner death,
any remaining annuity benefit payments will continue to the surviving Joint
Owner in accordance with the terms of the annuity benefit payment option
selected prior to the Annuity Date.
 
If the Owner selects an annuity payout option which provides for the
continuation of payments after the death of an Annuitant, upon the death of an
Annuitant on or after the Annuity Date, any remaining payments will continue to
be paid to the Owner or the payee the Owner has designated.
 
VARIABLE LIFE ANNUITY WITH PAYMENTS GUARANTEED FOR TEN YEARS.  This variable
annuity is payable periodically during the lifetime of the Annuitant with the
guarantee that if the Annuitant should die before the guaranteed number of
payments have been made, the remaining annuity benefit payments will continue to
be paid.
 
VARIABLE LIFE ANNUITY PAYABLE PERIODICALLY DURING LIFETIME OF THE ANNUITANT
ONLY.  This variable annuity is payable during the Annuitant's life. It would be
possible under this option for the Owner to receive only one annuity benefit
payment if the Annuitant dies prior to the due date of the second annuity
benefit payment, two annuity benefit payments if the Annuitant dies before the
due date of the third annuity benefit payment, and so on. Payments will
continue, however, during the lifetime of the Annuitant, no matter how long he
or she lives.
 
                                       31
<PAGE>
UNIT REFUND VARIABLE LIFE ANNUITY.  This is an annuity payable periodically
during the lifetime of the Annuitant with the guarantee that if the Annuitant
dies and (1) exceeds (2), then periodic variable annuity benefit payments will
continue to the beneficiary until the number of such payments equals the number
determined in (1).
 
    Where:    (1)  is the dollar amount of the Accumulated Value divided by the
                   dollar amount of the first payment, and
 
              (2)  is the number of payments paid prior to the death of the
                   Annuitant.
 
JOINT AND SURVIVOR VARIABLE LIFE ANNUITY.  This variable annuity is payable
during the joint lifetime of the Annuitant and another individual (i.e. the
beneficiary or a Joint Annuitant), and then continues thereafter during the
lifetime of the survivor. The amount of each payment during the lifetime of the
survivor is based on the same number of Annuity Units which applied during their
joint lifetime. There is no minimum number of payments under this option.
 
JOINT AND TWO-THIRDS SURVIVOR VARIABLE LIFE ANNUITY.  This variable annuity is
payable during the joint lifetime of the Annuitant and another individual (i.e.
the beneficiary or a Joint Annuitant), and then continues thereafter during the
lifetime of the survivor. The amount of each periodic payment during the
lifetime of the survivor, however, is based upon two-thirds of the number of
Annuity Units which applied during their joint lifetime. There is no minimum
number of payments under this option.
 
PERIOD CERTAIN VARIABLE ANNUITY.  This variable annuity has periodic payments
for a stipulated number of years ranging from one to thirty. If the Annuitant
dies before the end of the period, remaining payments will continue to be paid.
This option may be commutable or noncommutable. A commutable option provides the
Owner with the right to request a lump sum payment of any remaining balance
after annuity payments have commenced. Under a non-commutable period certain
option, the Owner may not request a lump sum payment. See "ANNUITY BENEFIT
PAYMENTS" in the SAI.
 
It should be noted that the period certain option does not involve a life
contingency. In the computation of the payments under this option, the charge
for annuity rate guarantees, which includes a factor for mortality risks, is
made. Although not contractually required to do so, the Company currently
follows a practice of permitting persons receiving payments under a period
certain option to elect to convert to a variable annuity involving a life
contingency. The Company may discontinue or change this practice at any time,
but not with respect to election of the option made prior to the date of any
change in this practice.
 
L. ANNUITY BENEFIT PAYMENTS
 
THE ANNUITY UNIT.  On and after the Annuity Date, the Annuity Unit is a measure
of the value of the monthly annuity benefit payments under a variable annuity
payout option. The value of an Annuity Unit in each Sub-Account on its inception
date was set at $1.00. The value of an Annuity Unit under a Sub-Account on any
Valuation Date thereafter is equal to the value of such unit on the immediately
preceding Valuation Date, multiplied by the product of (1) the net investment
factor of the Sub-Account for the current Valuation Period, and (2) a factor to
adjust benefits to neutralize the assumed interest rate. The assumed interest
rate, discussed below, is incorporated in the variable annuity payout options
offered in the Contract.
 
DETERMINATION OF THE FIRST AND SUBSEQUENT ANNUITY BENEFIT PAYMENTS.  The first
periodic annuity benefit payment is based upon the Accumulated Value as of a
date not more than four weeks preceding the date that the first annuity benefit
payment is due. Variable annuity benefit payments are due on the first of a
month, which is the date the payment is to be received by the Annuitant, and
currently are based on unit values as of the 15th day of the preceding month.
 
                                       32
<PAGE>
The Contract provides annuity rates which determine the dollar amount of the
first periodic payment under each form of annuity for each $1,000 of applied
value. For life contingency options and non-commutable period certain options of
ten or more years (six or more years under New York contracts), the annuity
value is the Accumulated Value less any premium taxes and adjusted for any
Market Value Adjustment. For commutable period certain options or any period
certain option less than ten years (less than six years under New York
contracts), the value is the Surrender Value less any premium tax. For a death
benefit annuity, the annuity value will be the amount of the death benefit. The
annuity rates in the Contract are based on a modification of the Annuity 2000
Individual Mortality Table.
 
The amount of the first monthly payment depends upon the form of annuity
selected, the sex (however, see "M. NORRIS Decision") and age of the Annuitant
and/or beneficiary, if applicable, and the value of the amount applied under the
annuity option. The variable annuity payout options offered by the Company are
based on a 3.5% assumed interest rate. Variable payments are affected by the
assumed interest rate used in calculating the annuity option rates. Variable
annuity benefit payments will increase over periods when the actual net
investment result of the Sub-Accounts funding the annuity exceeds the equivalent
of the assumed interest rate for the period. Variable annuity benefit payments
will decrease over periods when the actual net investment result of the
respective Sub-Account is less than the equivalent of the assumed interest rate
for the period.
 
The dollar amount of the first periodic annuity benefit payment under life
annuity options and non-commutable period certain options of ten years or more
(six or more years under New York contracts) is determined by multiplying (1)
the Accumulated Value applied under that option (after application of any Market
Value Adjustment and less premium tax, if any) divided by $1,000, by (2) the
applicable amount of the first monthly payment per $1,000 of value. For
commutable period certain options and any period certain option of less than ten
years (less than six years under New York contracts), the Surrender Value less
premium taxes, if any, is used rather than the Accumulated Value. The dollar
amount of the first variable annuity benefit payment is then divided by the
value of an Annuity Unit of the selected Sub-Accounts to determine the number of
Annuity Units represented by the first payment. This number of Annuity Units
remains fixed under all annuity options except the joint and two-thirds survivor
annuity option. For each subsequent payment, the dollar amount of the variable
annuity benefit payment is determined by multiplying this fixed number of
Annuity Units by the value of an Annuity Unit on the applicable Valuation Date.
After the first benefit payment, the dollar amount of each periodic variable
annuity benefit payment will vary with subsequent variations in the value of the
Annuity Unit of the selected Sub-Accounts. The dollar amount of each fixed
amount annuity benefit payment is fixed and will not change, except under the
joint and two-thirds survivor annuity option.
 
From time to time, the Company may offer Owners both fixed and variable annuity
rates more favorable than those contained in the Contract. Any such rates will
be applied uniformly to all Owners of the same class.
 
For an illustration of a variable annuity benefit payment calculation using a
hypothetical example, see "ANNUITY BENEFIT PAYMENTS" in the SAI.
 
M. NORRIS DECISION
 
In the case of ARIZONA GOVERNING COMMITTEE V. NORRIS, the United States Supreme
Court ruled that, in connection with retirement benefit options offered under
certain employer-sponsored employee benefit plans, annuity options based on
sex-distinct actuarial tables are not permissible under Title VII of the Civil
Rights Act of 1964. The ruling requires that benefits derived from contributions
paid into a plan after August 1, 1983 be calculated without regard to the sex of
the employee. Annuity benefits attributable to payments received by the Company
under a Contract issued in connection with an employer-sponsored benefit plan
affected by the NORRIS decision will be based on the greater of (1) the
Company's unisex non-guaranteed current annuity option rates, or (2) the
guaranteed unisex rates described in such Contract, regardless of whether the
Annuitant is male or female.
 
                                       33
<PAGE>
N. COMPUTATION OF VALUES
 
THE ACCUMULATION UNIT.  Each net payment is allocated to the accounts selected
by the Owner. Allocations to the Sub-Accounts are credited to the Contract in
the form of Accumulation Units. Accumulation Units are credited separately for
each Sub-Account. The number of Accumulation Units of each Sub-Account credited
to the Contract is equal to the portion of the net payment allocated to the
Sub-Account, divided by the dollar value of the applicable Accumulation Unit as
of the Valuation Date the payment is received at the Principal Office. The
number of Accumulation Units resulting from each payment will remain fixed
unless changed by a subsequent split of Accumulation Unit value, a transfer, a
withdrawal or surrender. The dollar value of an Accumulation Unit of each
Sub-Account varies from Valuation Date to Valuation Date based on the investment
experience of that Sub-Account, and will reflect the investment performance,
expenses and charges of its Underlying Portfolios. The value of an Accumulation
Unit at inception was set at $1.00 on the first Valuation Date for each
Sub-Account.
 
Allocations to the Guarantee Period Accounts and the Fixed Account are not
converted into Accumulation Units, but are credited interest at a rate
periodically set by the Company. See APPENDIX B, "THE MARKET VALUE ADJUSTMENT."
 
The Accumulated Value under the Contract is determined by (1) multiplying the
number of Accumulation Units in each Sub-Account by the value of an Accumulation
Unit of that Sub-Account on the Valuation Date, (2) adding the products, and (3)
adding the amount of the accumulations in the Fixed Account and Guarantee Period
Accounts, if any.
 
NET INVESTMENT FACTOR.  The Net Investment Factor is an index that measures the
investment performance of a Sub-Account from one Valuation Period to the next.
This factor is equal to 1.000000 plus the result from dividing (1) by (2) and
subtracting (3) and (4) where:
 
(1) is the investment income of a Sub-Account for the Valuation Period,
    including realized or unrealized capital gains and losses during the
    Valuation Period, adjusted for provisions made for taxes, if any;
 
(2) is the value of that Sub-Account's assets at the beginning of the Valuation
    Period;
 
(3) is a charge for mortality and expense risks equal to 1.25% on an annual
    basis of the daily value of the Sub-Account's assets; and
 
(4) is an administrative charge equal to 0.15% on an annual basis of the daily
    value of the Sub-Account's assets.
 
The dollar value of an Accumulation Unit as of a given Valuation Date is
determined by multiplying the dollar value of the corresponding Accumulation
Unit as of the immediately preceding Valuation Date by the appropriate net
investment factor.
 
For an illustration of an Accumulation Unit calculation using a hypothetical
example see "ANNUITY BENEFIT PAYMENTS" in the SAI.
 
                             CHARGES AND DEDUCTIONS
 
Deductions under the Contract and charges against the assets of the Sub-Accounts
are described below. Other deductions and expenses paid out of the assets of the
Underlying Portfolios are described in the prospectus and SAI for the Fund.
 
A. VARIABLE ACCOUNT DEDUCTIONS
 
MORTALITY AND EXPENSE RISK CHARGE.  The Company makes a daily charge equal to an
annual rate of 1.25% of the value of each Sub-Account's assets to cover the
mortality and expense risk which the Company assumes
 
                                       34
<PAGE>
in relation to the variable portion of the Contract. The charge is imposed
during both the accumulation phase and the annuity payout phase. The mortality
risk arises from the Company's guarantee that it will make annuity benefit
payments in accordance with annuity rate provisions established at the time the
Contract is issued for the life of the Annuitant (or in accordance with the
annuity option selected), no matter how long the Annuitant (or other individual)
lives and no matter how long all Annuitants as a class live. Therefore, the
mortality charge is deducted during the annuity payout phase on all Contracts,
including those that do not involve a life contingency, even though the Company
does not bear direct mortality risk with respect to variable annuity settlement
options that do not involve life contingencies. The expense risk arises from the
Company's guarantee that the charges it makes will not exceed the limits
described in the Contract and in this Prospectus.
 
If the charge for mortality and expense risks is not sufficient to cover actual
mortality experience and expenses, the Company will absorb the losses. If
expenses are less than the amounts provided to the Company by the charge, the
difference will be a profit to the Company. To the extent this charge results in
a profit to the Company, such profit will be available for use by the Company
for, among other things, the payment of distribution, sales and other expenses.
Since mortality and expense risks involve future contingencies which are not
subject to precise determination in advance, it is not feasible to identify
specifically the portion of the charge which is applicable to each. The Company
intends to recoup commissions and other sales expenses through profits from the
Company's General Account, which may include amounts derived from mortality and
expense risk charges.
 
ADMINISTRATIVE EXPENSE CHARGE.  The Company assesses each Sub-Account with a
daily charge equal to an annual rate of 0.15% of the average daily net assets of
the Sub-Account. The charge is imposed during both the accumulation phase and
the annuity payout phase. The daily administrative expense charge is assessed to
help defray administrative expenses actually incurred in the administration of
the Sub-Account, without profits. There is no direct relationship, however,
between the amount of administrative expenses imposed on a given Contract and
the amount of expenses actually attributable to that Contract.
 
Deductions for the Contract fee (see B. "Contract Fee" below) and for the
administrative expense charge are designed to reimburse the Company for the cost
of administration and related expenses and are not expected to be a source of
profit. The administrative functions and expense assumed by the Company in
connection with the Variable Account and the Contract include, but are not
limited to, clerical, accounting, actuarial and legal services, rent, postage,
telephone, office equipment and supplies, expenses of preparing and printing
registration statements, expense of preparing and typesetting prospectuses and
the cost of printing prospectuses not allocable to sales expense, filing and
other fees.
 
OTHER CHARGES.  Because the Sub-Accounts purchase shares of the Underlying
Portfolios, the value of the net assets of the Sub-Accounts will reflect the
investment advisory fee and other expenses incurred by the Underlying
Portfolios. The prospectus and SAI for the Fund contain additional information
concerning expenses of the Underlying Portfolios.
 
B. CONTRACT FEE
 
A $35 Contract fee currently is deducted on the Contract anniversary and upon
full surrender of the Contract if the Accumulated Value on any of these dates is
less than $75,000. (This fee may vary by state. See your Contract for more
information.) Where Contract value has been allocated to more than one account,
a percentage of the total Contract fee will be deducted from the value in each
account. The portion of the charge deducted from each account will be equal to
the percentage which the value in that account bears to the Accumulated Value
under the Contract. The deduction of the Contract fee from a Sub-Account will
result in cancellation of a number of Accumulation Units equal in value to the
percentage of the charge deducted from that account.
 
                                       35
<PAGE>
Where permitted by law, the Contract fee also may be waived for Contracts where,
on the date of issue, either the Owner or the Annuitant is within the following
classes of individuals: employees and registered representatives of any
broker-dealer which has entered into a sales agreement with the Company to sell
the Contract; employees of the Company, its affiliates and subsidiaries;
officers, directors, trustees and employees of any of the Portfolios; investment
managers or sub-advisers; and the spouses of and immediate family members
residing in the same household with such eligible persons. "Immediate family
members" means children, siblings, parents and grandparents.
 
C. OPTIONAL ENHANCED DEATH BENEFIT RIDER CHARGE
 
Subject to state availability, the Company offers an optional Enhanced Death
Benefit Rider that may be elected by the Owner. A separate monthly charge is
made for the rider. On the last day of each month and on the date the rider is
terminated, a charge equal to 1/12th of an annual rate of 0.25% is made against
the Accumulated Value of the Contract at that time. The charge is deducted in
arrears through a pro-rata reduction (based on relative values in Accumulation
Units of the Sub-Accounts, of dollar amounts in the Fixed Account, and of dollar
amounts in the Guarantee Period Accounts).
 
For a description of this rider, see "G. Death Benefit" under "DESCRIPTION OF
THE CONTRACT," above.
 
D. PREMIUM TAXES
 
Some states and municipalities impose a premium tax on variable annuity
contracts. State premium taxes currently range up to 3.5%.
 
The Company makes a charge for state and municipal premium taxes, when
applicable, and deducts the amount paid as a premium tax charge. The current
practice of the Company is to deduct the premium tax charge in one of two ways:
 
1.  if the premium tax was paid by the Company when payments were received, the
    premium tax charge is deducted on a pro-rata basis when withdrawals are
    made, upon surrender of the Contract, or when annuity benefit payments begin
    (the Company reserves the right instead to deduct the premium tax charge for
    these Contracts at the time the payments are received); or
 
2.  the premium tax charge is deducted when annuity benefit payments begin.
 
In no event will a deduction be taken before the Company has incurred a tax
liability under applicable state law.
 
The Company reserves the right to deduct the premium tax charge at the time
payments into the Contract are received. In addition, if no amount for premium
tax was deducted at the time the payment was received, but subsequently tax is
determined to be due prior to the Annuity Date, the Company reserves the right
to deduct the premium tax from the Contract value at the time such determination
is made.
 
E. TRANSFER CHARGE
 
The Company currently makes no charge for processing transfers. The Company
guarantees that the first 12 transfers in a Contract year will be free of
transfer charge, but reserves the right to assess a charge, guaranteed never to
exceed $25, for each subsequent transfer in a Contract year. For more
information, see "D. Transfer Privilege."
 
                                       36
<PAGE>
                           GUARANTEE PERIOD ACCOUNTS
 
Due to certain exemptive and exclusionary provisions in the securities laws,
interests in the Guarantee Period Accounts and the Company's Fixed Account are
not registered as an investment company under the provisions of the Securities
Act of 1933 (the "1933 Act") or the 1940 Act. Accordingly, the staff of the SEC
has not reviewed the disclosures in this Prospectus relating to the Guarantee
Period Accounts or the Fixed Account. Nevertheless, disclosures regarding the
Guarantee Period Accounts and the Fixed Account of the Contract or any fixed
benefits offered under these accounts may be subject to the provisions of the
1933 Act relating to the accuracy and completeness of statements made in the
Prospectus.
 
INVESTMENT OPTIONS.  In most jurisdictions, Guarantee Periods ranging from two
through ten years may be available. Each Guarantee Period established for the
Owner is accounted for separately in a non-unitized segregated account. Each
Guarantee Period Account provides for the accumulation of interest at a
Guaranteed Interest Rate. The Guaranteed Interest Rate on amounts allocated or
transferred to a Guarantee Period Account is determined from time to time by the
Company in accordance with market conditions. Once an interest rate is in effect
for a Guarantee Period Account, however, the Company may not change it during
the duration of the Guarantee Period. In no event will the Guaranteed Interest
Rate be less than 3%.
 
To the extent permitted by law, the Company reserves the right at any time to
offer Guarantee Periods with durations that differ from those which were
available when a Contract initially was issued and to stop accepting new
allocations, transfers or renewals to a particular Guarantee Period.
 
Owners may allocate net payments or make transfers from any of the Sub-Accounts,
the Fixed Account or an existing Guarantee Period Account to establish a new
Guarantee Period Account at any time prior to the Annuity Date. Transfers from a
Guarantee Period Account on any date other than on the day following the
expiration of that Guarantee Period will be subject to a Market Value
Adjustment. The Company establishes a separate investment account each time the
Owner allocates or transfers amounts to a Guarantee Period except that amounts
allocated to the same Guarantee Period on the same day will be treated as one
Guarantee Period Account. The minimum that may be allocated to establish a
Guarantee Period Account is $1,000. If less than $1,000 is allocated, the
Company reserves the right to apply that amount to the Money Market Portfolio.
The Owner may allocate amounts to any of the Guarantee Periods available.
 
At least 45 days (but not more than 75 days) prior to the end of a Guarantee
Period, the Company will notify the Owner in writing of the expiration of that
Guarantee Period. At the end of a Guarantee Period the Owner may transfer
amounts to the Sub-Accounts, the Fixed Account or establish a new Guarantee
Period Account of any duration then offered by the Company without a Market
Value Adjustment. If reallocation instructions are not received at the Principal
Office before the end of a Guarantee Period, the account value automatically
will be applied to a new Guarantee Period Account with the same duration unless
(1) less than $1,000 would remain in the Guarantee Period Account on its
expiration date, or (2) the Guarantee Period would extend beyond the Annuity
Date or is no longer available. In such cases, the Guarantee Period Account
value will be transferred to the Sub-Account investing in the Money Market
Portfolio. Where amounts have been renewed automatically in a new Guarantee
Period, it is the Company's current practice to give the Owner an additional 30
days to transfer out of the Guarantee Period Account without application of a
Market Value Adjustment. This practice may be discontinued or changed at the
Company's discretion. Under contracts issued in New York, the Company will
transfer monies out of the Guarantee Period Account without application of a
Market Value Adjustment if the Owner's request is received within ten days of
the renewal date.
 
MARKET VALUE ADJUSTMENT.  No Market Value Adjustment will be applied to
transfers, withdrawals, or a surrender from a Guarantee Period Account on the
expiration of its Guarantee Period. In addition, no negative Market Value
Adjustment will be applied to a death benefit although a positive Market Value
Adjustment, if any, will be applied to increase the value of the death benefit
when based on the Contract's Accumulated Value. See "G. Death Benefit." All
other transfers, withdrawals, or a surrender prior to the end of a Guarantee
Period will be subject to a Market Value Adjustment, which may increase or
decrease the account value.
 
                                       37
<PAGE>
Amounts applied under an annuity option are treated as withdrawals when
calculating the Market Value Adjustment. The Market Value Adjustment will be
determined by multiplying the amount taken from each Guarantee Period Account by
the market value factor. The market value factor for each Guarantee Period
Account is equal to:
 
                              [(1+i)/(1+j)]n/365-1
 
<TABLE>
<S>        <C>        <C>
where:             i  is the Guaranteed Interest Rate expressed as a decimal (for example 3% =
                      0.03) being credited to the current Guarantee Period;
                   j  is the new Guaranteed Interest Rate, expressed as a decimal, for a
                      Guarantee Period with a duration equal to the number of years remaining in
                      the current Guarantee Period, rounded to the next higher number of whole
                      years. If that rate is not available, the Company will use a suitable rate
                      or index allowed by the Department of Insurance; and
                   n  is the number of days remaining from the Effective Valuation Date to the
                      end of the current Guarantee Period.
</TABLE>
 
Based on the application of this formula, the value of a Guarantee Period
Account will increase after the Market Value Adjustment is applied if the then
current market rates are lower than the rate being credited to the Guarantee
Period Account. Similarly, the value of a Guarantee Period Account will decrease
after the Market Value Adjustment is applied if the then current market rates
are higher than the rate being credited to the Guarantee Period Account. The
Market Value Adjustment is limited, however, so that even if the account value
is decreased after application of a Market Value Adjustment, it will equal or
exceed the Owner's principal plus 3% earnings per year less applicable Contract
fees. Conversely, if the then current market rates are lower and the account
value is increased after the Market Value Adjustment is applied, the increase in
value is also affected by the minimum guaranteed rate of 3% such that the amount
that will be added to the Guarantee Period Account is limited to the difference
between the amount earned and the 3% minimum guaranteed earnings. For examples
of how the Market Value Adjustment works, see APPENDIX B, "THE MARKET VALUE
ADJUSTMENT".
 
BUILD WITH INTEREST AND GROWTH PROGRAM.  Under this feature, the Owner elects a
Guarantee Period and one or more Sub-Accounts. The Company will then compute the
proportion of the initial payment that must be allocated to the Guarantee Period
selected, assuming no transfers or withdrawals, in order to ensure that on the
last day of the Guarantee Period it will equal the amount of the entire initial
payment. The required amount then will be allocated to the pre-selected
Guarantee Period Account and the remaining balance to the other investment
options selected by the Owner in accordance with the procedures described in "A.
Payments."
 
WITHDRAWALS.  Prior to the Annuity Date, the Owner may make withdrawals of
amounts held in the Guarantee Period Accounts. Withdrawals from these accounts
will be made in the same manner and be subject to the same rules as set forth
under "E. Surrender" and "F. Withdrawals." In addition, the following provisions
also apply to withdrawals from a Guarantee Period Account: (1) a Market Value
Adjustment will apply to all withdrawals, unless made at the end of the
Guarantee Period; and (2) the Company reserves the right to defer payments of
amounts withdrawn from a Guarantee Period Account for up to six months from the
date it receives the withdrawal request. If deferred for 30 days or more, the
Company will pay interest on the amount deferred at a rate of at least 3%.
 
In the event that a Market Value Adjustment applies to a withdrawal of a portion
of the value of a Guarantee Period Account, it will be calculated on the amount
requested and deducted or added to the amount remaining in the Guarantee Period
Account. If the entire amount in a Guarantee Period Account is requested, the
adjustment will be made to the amount payable.

                           FEDERAL TAX CONSIDERATIONS
 
The effect of federal income taxes on the value of a Contract, on withdrawals or
surrenders, on annuity benefit payments, and on the economic benefit to the
Owner or beneficiary depends upon a variety of factors. The following discussion
is based upon the Company's understanding of current federal income tax laws as
they are interpreted as of the date of this Prospectus. No representation is
made regarding the likelihood of continuation of current federal income tax laws
or of current interpretations by the IRS. In addition, this discussion does not
address state or local tax consequences that may be associated with the
Contract.
 
IT SHOULD BE RECOGNIZED THAT THE FOLLOWING DISCUSSION OF FEDERAL INCOME TAX
ASPECTS OF AMOUNTS RECEIVED UNDER VARIABLE ANNUITY CONTRACTS IS NOT EXHAUSTIVE,
DOES NOT PURPORT TO COVER ALL SITUATIONS, AND IS NOT INTENDED AS TAX ADVICE. A
QUALIFIED TAX ADVISER ALWAYS SHOULD BE CONSULTED WITH REGARD TO THE APPLICATION
OF LAW TO INDIVIDUAL CIRCUMSTANCES.
 
The Company intends to make a charge for any effect which the income, assets, or
existence of the Contract, the Variable Account or the Sub-Accounts may have
upon its tax. The Variable Account presently is not subject to tax, but the
Company reserves the right to assess a charge for taxes should the Variable
Account at any time become subject to tax. Any charge for taxes will be assessed
on a fair and equitable basis in order to preserve equity among classes of
Owners and with respect to each separate account as though that separate account
were a separate taxable entity.
 
The Variable Account is considered a part of and taxed with the operations of
the Company. The Company is taxed as a life insurance company under Subchapter L
of the Code. The Company files a consolidated tax return with its affiliates.
 
Under Section 817(h) of the Code, a variable annuity contract will not be
treated as an annuity contract for any period during which the investments made
by the Separate Account or Underlying Fund are not adequately diversified in
accordance with regulations prescribed by the Treasury Department. If a Contract
is not treated as an annuity contract, the income on a contract, for any taxable
year of an owner, would be treated as ordinary income received or accrued by the
owner. The IRS has issued regulations relating to the diversification
requirements for variable annuity and variable life insurance contracts under
Section 817(h) of the Code. The regulations provide that the investments of a
segregated asset account underlying a variable annuity contract are adequately
diversified if no more than 55% of the value of its assets is represented by any
one investment, no more than 70% by any two investments, no more than 80% by any
three investments, and no more than 90% by any four investments. It is
anticipated that the Portfolios of the Fund will comply with the current
diversification requirements. In the event that future IRS regulations and/or
rulings would require Contract modifications in order to remain in compliance
with the diversification standards, the Company will make reasonable efforts to
comply, and it reserves the right to make such changes as it deems appropriate
for that purpose.
 
In addition, in order for a variable annuity contract to qualify for tax
deferral, the Company, and not the variable contract owner, must be considered
to be the owner for tax purposes of the assets in the segregated asset account
underlying the variable annuity contract. In certain circumstances, however,
variable annuity contract owners may be considered the owners of these assets
for federal income tax purposes. Specifically, the IRS has stated in published
rulings that a variable annuity contract owner may be considered the owner of
segregated account assets if the contract owner possesses incidents of ownership
in those assets, such as the ability to exercise investment control over the
assets. The Treasury Department has also announced, in connection with the
issuance of regulations concerning investment diversification, that those
regulations "do not provide guidance governing the circumstances in which
investor control of the investments of a segregated asset account may cause the
investor (i.e., the contract owner), rather than the insurance company, to be
treated as the owner of the assets in the account." This announcement also
states that guidance would be issued by way of regulations or rulings on the
"extent to which policyholders may direct their investments to particular
sub-accounts without being treated as owners of the underlying assets." As of
the date of this Prospectus, no
 
                                       39
<PAGE>
such guidance has been issued. The Company therefore additionally reserves the
right to modify the Contract as necessary in order to attempt to prevent a
contract owner from being considered the owner of a pro rata share of the assets
of the segregated asset account underlying the variable annuity contracts.
 
A. QUALIFIED AND NON-QUALIFIED CONTRACTS
 
From a federal tax viewpoint there are two types of variable annuity contracts:
"qualified" contracts and "non-qualified" contracts. A qualified contract is one
that is purchased in connection with a retirement plan which meets the
requirements of Sections 401, 403, or 408 of the Code, while a non-qualified
contract is one that is not purchased in connection with one of the indicated
retirement plans. The tax treatment for certain withdrawals or surrenders will
vary, depending on whether they are made from a qualified contract or a non-
qualified contract. For more information on the tax provisions applicable to
qualified contracts, see Section D below.
 
B. TAXATION OF THE CONTRACT IN GENERAL
 
The Company believes that the Contract described in this Prospectus will, with
certain exceptions (see "Non-Natural Owners" below), be considered an annuity
contract under Section 72 of the Code. Please note, however, if the Owner
chooses an Annuity Date beyond the Owner's 85th birthday, it is possible that
the Owner will be taxed on the annual increase in the Accumulated Value. The
Owner should consult tax and financial advisors for more information. This
section governs the taxation of annuities. The following discussion concerns
annuities subject to Section 72.
 
WITHDRAWALS PRIOR TO ANNUITIZATION.  With certain exceptions, any increase in
the Contract's Accumulated Value is not taxable to the Owner until it is
withdrawn from the Contract. If the Contract is surrendered or amounts are
withdrawn prior to the Annuity Date, any withdrawal of investment gain in value
over the cost basis of the Contract will be taxed as ordinary income. Under the
current provisions of the Code, amounts received under an annuity contract prior
to annuitization (including payments made upon the death of the annuitant or
owner), generally are first attributable to any investment gains credited to the
contract over the taxpayer's "investment in the contract." Such amounts will be
treated as gross income subject to federal income taxation. "Investment in the
contract" is the total of all payments to the Contract which were not excluded
from the Owner's gross income less any amounts previously withdrawn which were
not included in income. Section 72(e)(11)(A)(ii) requires that all non-qualified
deferred annuity contracts issued by the same insurance company to the same
owner during a single calendar year be treated as one contract in determining
taxable distributions.
 
ANNUITY PAYOUTS AFTER ANNUITIZATION.  When annuity benefit payments are
commenced under the Contract, generally a portion of each payment may be
excluded from gross income. The excludable portion generally is determined by a
formula that establishes the ratio that the investment in the Contract bears to
the expected return under the Contract. The portion of the payment in excess of
this excludable amount is taxable as ordinary income. Once all the investment in
the Contract is recovered, the entire payment is taxable to the Owner, whether
or not the Owner is receiving the payments. If an Owner dies before the
investment in the Contract is recovered, a deduction for the difference is
allowed on the Owner's final tax return.
 
PENALTY ON DISTRIBUTION.  A 10% penalty tax may be imposed on the withdrawal of
investment gains if the withdrawal is made prior to age 59 1/2. The penalty tax
will not be imposed on withdrawals taken on or after age 59 1/2 or if the
withdrawal follows the death of an Owner (or, if the Owner is not an individual,
the death of the primary Annuitant, as defined in the Code) or, in the case of
the Owner's "total disability" (as defined in the Code). Furthermore, under
Section 72 of the Code, this penalty tax will not be imposed, irrespective of
age, if the amount received is one of a series of "substantially equal" periodic
payments made at least annually for the life or life expectancy of the Owner.
This requirement is met when the Owner elects to have distributions made over
the Owner's life expectancy, or over the joint life expectancy of the Owner and
beneficiary. The requirement that the amount be paid out as one of a series of
"substantially equal" periodic payments is met
 
                                       40
<PAGE>
when the number of units withdrawn to make each distribution is substantially
the same. Any modification, other than by reason of death or disability, of
distributions which are part of a series of substantially equal periodic
payments that occurs before the Owner's age 59 1/2 or five years, will subject
the Owner to the 10% penalty tax on the prior distributions. In addition to the
exceptions above, the penalty tax will not apply to withdrawals from a qualified
Contract made to an employee who has terminated employment after reaching age
55.
 
In a Private Letter Ruling, the IRS took the position that where distributions
from a variable annuity contract were determined by amortizing the accumulated
value of the contract over the taxpayer's remaining life expectancy (such as
under the Contract's LED option), and the option could be changed or terminated
at any time, the distributions failed to qualify as part of a "series of
substantially equal payments" within the meaning of Section 72 of the Code. The
distributions, therefore, were subject to the 10% federal penalty tax. This
Private Letter Ruling may be applicable to an Owner who receives distributions
under the LED option prior to age 59 1/2. Subsequent Private Letter Rulings,
however, have treated LED-type withdrawal programs as effectively avoiding the
10% penalty tax. The position of the IRS on this issue is unclear.
 
ASSIGNMENTS OR TRANSFERS.  If the Owner transfers (assigns) the Contract to
another individual as a gift prior to the Annuity Date, the Code provides that
the Owner will incur taxable income at the time of the transfer. An exception is
provided for certain transfers between spouses. The amount of taxable income
upon such taxable transfer is equal to any investment gain in value over the
Owner's cost basis at the time of the transfer. The transfer also is subject to
federal gift tax provisions.
 
NON-NATURAL OWNERS.  As a general rule, deferred annuity contracts owned by
"non-natural persons" (e.g., a corporation) are not treated as annuity contracts
for federal tax purposes, and the investment income attributable to
contributions made after February 28, 1986 is taxed as ordinary income that is
received or accrued by the owner during the taxable year. This rule does not
apply to annuity contracts purchased with a single payment when the annuity date
is no later than a year from the issue date or to deferred annuities owned by
qualified employer plans, estates, employers with respect to a terminated
pension plan, and entities other than employers, such as a trust, holding an
annuity as an agent for a natural person. This exception, however, will not
apply in cases of any employer who is the owner of an annuity contract under a
non-qualified deferred compensation plan.
 
DEFERRED COMPENSATION PLANS OF STATE AND LOCAL GOVERNMENTS AND TAX-EXEMPT
ORGANIZATIONS. Under Section 457 of the Code, deferred compensation plans
established by governmental and certain other tax-exempt employers for their
employees may invest in annuity contracts. Contributions and investment earnings
are not taxable to employees until distributed; however, with respect to
payments made after February 28, 1986, a Contract owned by a state or local
government or a tax-exempt organization will not be treated as an annuity under
Section 72 as well. In addition, plan assets are treated as property of the
employer, and are subject to the claims of the employer's general creditors.
 
C. TAX WITHHOLDING
 
The Code requires withholding with respect to payments or distributions from
non-qualified contracts and IRAs, unless a taxpayer elects not to have
withholding. A 20% withholding requirement applies to distributions from most
other qualified contracts. In addition, the Code requires reporting to the IRS
of the amount of income received with respect to payment or distributions from
annuities.
 
The tax treatment of certain withdrawals or surrenders of the non-qualified
Contracts offered by this Prospectus will vary according to whether the amount
withdrawn or surrendered is allocable to an investment in the Contract made
before or after certain dates.
 
                                       41
<PAGE>
D. PROVISIONS APPLICABLE TO QUALIFIED EMPLOYER PLANS
 
The tax rules applicable to qualified retirement plans, as defined by the Code,
are complex and vary according to the type of plan. Benefits under a qualified
plan may be subject to that plan's terms and conditions irrespective of the
terms and conditions of any annuity contract used to fund such benefits. As
such, the following is simply a general description of various types of
qualified plans that may use the Contract. Before purchasing any annuity
contract for use in funding a qualified plan, more specific information should
be obtained.
 
Qualified Contracts may include special provisions (endorsements) changing or
restricting rights and benefits otherwise available to Owners of non-qualified
Contracts. Individuals purchasing a qualified Contract should carefully review
any such changes or limitations which may include restrictions to ownership,
transferability, assignability, contributions, and distributions.
 
CORPORATE AND SELF-EMPLOYED ("H.R. 10" AND "KEOGH") 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 tax-favored retirement
plans for employees. The Self-Employed Individuals' Tax Retirement Act of 1962,
as amended, permits self-employed individuals to establish similar plans for
themselves and their employees. Employers intending to use qualified Contracts
in connection with such plans should seek competent advice as to the suitability
of the Contracts to their specific needs and as to applicable Code limitations
and tax consequences.
 
The Company can provide prototype plans for certain pension or profit sharing
plans for review by the plan's legal counsel. For information, ask your
financial representative.
 
INDIVIDUAL RETIREMENT ANNUITIES.  Section 408 of the Code permits eligible
individuals to contribute to an individual retirement program known as an
Individual Retirement Annuity ("IRA"). Note: This term covers all IRAs permitted
under Section 408(b) of the Code, including Roth IRAs. IRAs are subject to
limits on the amounts that may be contributed, the persons who may be eligible,
and on the time when distributions may commence. In addition, certain
distributions from other types of retirement plans may be "rolled over," on a
tax-deferred basis, to an IRA. Purchasers of an IRA Contract will be provided
with supplementary information as may be required by the IRS or other
appropriate agency, and will have the right to Cancel the Contract as described
in this Prospectus. See "B. Right to Cancel Individual Retirement Annuity."
 
Eligible employers that meet specified criteria may establish simplified
employee pension plans (SEP-IRAs) or SIMPLE IRA plans for their employees using
IRAs. Employer contributions that may be made to such plans are larger than the
amounts that may be contributed to regular IRAs and may be deductible to the
employer.
 
TAX-SHELTERED ANNUITIES ("TSAS").  Under the provisions of Section 403(b) of the
Code, payments made to contracts purchased for employees under annuity plans
adopted by public school systems and certain organizations which are tax-exempt
under Section 501(c)(3) of the Code are excludable from the gross income of such
employees to the extent that total annual payments do not exceed the maximum
contribution permitted under the Code. Purchasers of TSA Contracts should seek
competent advice as to eligibility, limitations on permissible payments and
other tax consequences associated with the contracts.
 
Withdrawals or other distributions attributable to salary reduction
contributions (including earnings thereon) made to a TSA Contract after December
31, 1988, may not begin before the employee attains age 59 1/2, separates from
service, dies or becomes disabled. In the case of hardship, an Owner may
withdraw amounts contributed by salary reduction, but not the earnings on such
amounts. Even though a distribution may be permitted under these rules (e.g.,
for hardship or after separation from service), it may be subject to a 10%
penalty tax as a premature distribution, in addition to income tax.
 
                                       42
<PAGE>
TEXAS OPTIONAL RETIREMENT PROGRAM.  Distributions under a TSA contract issued to
participants in the Texas Optional Retirement Program may not be received except
in the case of the participant's death, retirement or termination of employment
in the Texas public institutions of higher education. These additional
restrictions are imposed under the Texas Government Code and a prior opinion of
the Texas Attorney General.
 
                                    REPORTS
 
An Owner is sent a report semi-annually which states certain financial
information about the Underlying Portfolios. The Company also will furnish an
annual report to the Owner containing a statement of his or her account,
including Accumulation Unit values and other information as required by
applicable law, rules and regulations.
 
                        LOANS (QUALIFIED CONTRACTS ONLY)
 
Loans are available to owners of TSA contracts (i.e., contracts issued under
Section 403(b) of the Code) and to contracts issued to plans qualified under
Sections 401(a) and 401(k) of the Code. Loans are subject to provisions of the
Code and to applicable qualified retirement plan rules. Tax advisers and plan
fiduciaries should be consulted prior to exercising loan privileges.
 
Loaned amounts will be withdrawn first from Sub-Account and Fixed Account values
on a pro-rata basis until exhausted. Thereafter, any additional amounts will be
withdrawn from the Guarantee Period Accounts (pro rata by duration and LIFO
within each duration), subject to any applicable Market Value Adjustments. The
maximum loan amount will be determined under the Company's maximum loan formula.
The minimum loan amount is $1,000. Loans will be secured by a security interest
in the Contract and the amount borrowed will be transferred to a loan asset
account within the Company's General Account, where it will accrue interest at a
specified rate below the then-current loan rate. Generally, loans must be repaid
within five years or less, and repayments must be made quarterly and in
substantially equal amounts. Repayments will be allocated pro rata in accordance
with the most recent payment allocation, except that any allocations to a
Guarantee Period Account will be allocated instead to the Money Market
Portfolio.
 
               ADDITION, DELETION OR SUBSTITUTION OF INVESTMENTS
 
The Company reserves the right, subject to applicable law, to make additions to,
deletions from, or substitutions for the shares that are held in the
Sub-Accounts or that the Sub-Accounts may purchase. If the shares of any
Underlying Portfolio no longer are available for investment or if, in the
Company's judgment, further investment in any Underlying Portfolio should become
inappropriate in view of the purposes of the Variable Account or the affected
Sub-Account, the Company may withdraw the shares of that Underlying Portfolio
and substitute shares of another registered open-end management company. The
Company will not substitute any shares attributable to the Contract interest in
a Sub-Account without notice to the Owner and prior approval of the SEC and
state insurance authorities, to the extent required by the 1940 Act or other
applicable law. The Variable Account may, to the extent permitted by law,
purchase other securities for other contracts or permit a conversion between
contracts upon request by an Owner.
 
The Company also reserves the right to establish additional sub-accounts of the
Variable Account, each of which would invest in shares corresponding to a new
Underlying Portfolio or in shares of another investment company having a
specified investment objective. Subject to applicable law and any required SEC
approval, the Company may, in its sole discretion, establish new sub-accounts or
eliminate one or more Sub-Accounts if marketing needs, tax considerations or
investment conditions warrant. Any new Sub-Accounts may be made available to
existing Owners on a basis to be determined by the Company.
 
Shares of the Underlying Portfolios may be issued to variable accounts of the
Company and its affiliates which issue variable life contracts ("mixed
funding"). Shares of the Portfolios may be also issued to other unaffiliated
insurance companies ("shared funding"). It is conceivable that in the future
such mixed funding
 
                                       43
<PAGE>
or shared funding may be disadvantageous for variable life owners or variable
annuity owners. Although neither the Company nor the Fund currently foresees any
such disadvantages to either variable life owners or variable annuity owners,
the Company and the trustee intend to monitor events in order to identify any
material conflicts between such owners, and to determine what action, if any,
should be taken in response thereto. If it were concluded that separate funds
should be established for variable life and variable annuity separate accounts,
the Company will bear the attendant expenses.
 
If any of these substitutions or changes is made, the Company may endorse the
Contract to reflect the substitution or change, and will notify Owners of all
such changes. If the Company deems it to be in the best interest of Owners, and
subject to any approvals that may be required under applicable law, the Variable
Account or any Sub-Accounts may be operated as a management company under the
1940 Act, may be deregistered under the 1940 Act if registration is no longer
required, or may be combined with other Sub-Accounts or other separate accounts
of the Company.
 
The Company reserves the right, subject to compliance with applicable law, to:
(1) transfer assets from the Variable Account or any of its Sub-Accounts to
another of the Company's separate accounts or sub-accounts having assets of the
same class; (2) to operate the Variable Account or any Sub-Account as a
management investment company under the 1940 Act or in any other form permitted
by law; (3) to deregister the Variable Account under the 1940 Act in accordance
with the requirements of the 1940 Act; (4) to substitute the shares of any other
registered investment company for the Underlying Portfolio shares held by a
Sub-Account, in the event that Underlying Portfolio shares are unavailable for
investment, or if the Company determines that further investment in such
Underlying Fund shares is inappropriate in view of the purpose of the Sub-
Account; (5) to change the methodology for determining the net investment
factor,; and (6) to change the names of the Variable Account or of the
Sub-Accounts. In no event will the changes described above be made without
notice to Owners in accordance with the 1940 Act.
 
                   CHANGES TO COMPLY WITH LAW AND AMENDMENTS
 
The Company reserves the right, without the consent of Owners, to suspend sales
of the Contract as presently offered, and to make any change to provisions of
the Contract to comply with, or give Owners the benefit of, any federal or state
statute, rule or regulation, including but not limited to requirements for
annuity contracts and retirement plans under the Code. Any such changes will
apply uniformly to all Contracts that are affected. You will be given written
notice of such changes.
 
                                 VOTING RIGHTS
 
The Company will vote Underlying Portfolio shares held by each Sub-Account in
accordance with instructions received from Owners. Each person having a voting
interest in a Sub-Account will be provided with proxy materials of the
Underlying Portfolio, together with a form with which to give voting
instructions to the Company. Shares for which no timely instructions are
received will be voted in proportion to the instructions which are received. The
Company also will vote shares in a Sub-Account that it owns and which are not
attributable to Contracts in the same proportion. If the 1940 Act or any rules
thereunder should be amended or if the present interpretation of the 1940 Act or
such rules should change, and as a result the Company determines that it is
permitted to vote shares in its own right, whether or not such shares are
attributable to the Contract, the Company reserves the right to do so.
 
The number of votes which an Owner may cast will be determined by the Company as
of the record date established by the Underlying Portfolio. During the
accumulation period, the number of Underlying Portfolio shares attributable to
each Owner will be determined by dividing the dollar value of the Accumulation
Units of the Sub-Account credited to the Contract by the net asset value of one
Underlying Portfolio share. During the annuity period, the number of Underlying
Portfolio shares attributable to each Owner will be determined by dividing the
reserve held in each Sub-Account for the Owner's variable annuity by the net
asset value of one
 
                                       44
<PAGE>
Underlying Portfolio share. Ordinarily, the Owner's voting interest in the
Underlying Portfolio will decrease as the reserve for the variable annuity is
depleted.
 
                                  DISTRIBUTION
 
The Contracts offered by this Prospectus may be purchased from certain
independent broker-dealers which are registered under the Securities and
Exchange Act of 1934 and members of the National Association of Securities
Dealers, Inc. ("NASD"). The Contracts also are offered through Allmerica
Investments, Inc., which is the principal underwriter and distributor of the
Contracts. Allmerica Investments, Inc., 440 Lincoln Street, Worcester, MA 01653,
is a registered broker-dealer, a member of the NASD and an indirectly wholly
owned subsidiary of First Allmerica.
 
The Company pays commissions, not to exceed 1.0% of payments, to broker-dealers
which sell the Contract, plus ongoing annual compensation of up to 1.0% of
Contract value. To the extent permitted by NASD rules, promotional incentives or
payments also may be provided to such broker-dealers based on sales volumes, the

                                 LEGAL MATTERS
 
There are no legal proceedings pending to which the Variable Account, its
principal underwriter or the Company is a party.
 
                              YEAR 2000 COMPLIANCE
 
The Year 2000 issue is the result of computer programs being written using two
digits rather than four to define the applicable year. Any of the Company's
computer programs that have date-sensitive software may recognize a date using
"00" as the year 1900 rather than the year 2000. This could result in a system
failure or miscalculations causing disruptions of operations, including, among
other things, a temporary inability to process transactions, send invoices or
engage in similar normal business activities.
 
Based on a third party assessment, the Company determined that significant
portions of its software required modification or replacement to enable its
computer systems to properly process dates beyond December 31, 1999. The Company
is presently completing the process of modifying or replacing existing software
and believes that this action will resolve the Year 2000 issue. However, if such
modifications and conversions are not made, or are not completed timely, or
should there be serious unanticipated interruptions from unknown sources, the
Year 2000 issue could have a material adverse impact on the operations of the
Company. Specifically, the Company could experience, among other things, an
interruption in its ability to collect and process premiums, process claim
payments, safeguard and manage its invested assets, accurately maintain
policyholder information, accurately maintain accounting records, and perform
customer service. Any of these specific events, depending on duration, could
have a material adverse impact on the results of operations and the financial
position of the Company.
 
The Company has initiated formal communications with all of its significant
suppliers and large customers to determine the extent to which the Company is
vulnerable to those third parties' failure to remediate their own Year 2000
issue. The Company's total Year 2000 project cost and estimates to complete the
project include the estimated costs and time associated with the impact of a
third party's Year 2000 issue, and are based on presently available information.
However, there can be no guarantee that the systems of other companies on which
the Company's systems rely will be timely converted, or that a failure to
convert by another company, or
 
                                       45
<PAGE>
a conversion that is incompatible with the Company's systems, would not have
material adverse effect on the Company. The Company does not believe that it has
material exposure to contingencies related to the Year 2000 issue for the
products it has sold. Although the Company does not believe that there is a
material contingency associated with the Year 2000 project, there can be no
assurance that exposure for material contingencies will not arise.
 
The Company will utilize both internal and external resources to reprogram or
replace, and test both information technology and embedded technology systems
for Year 2000 modifications. The Company plans to complete the mission critical
elements of the Year 2000 by December 31, 1998. The cost of the Year 2000
project will be expensed as incurred over the next two years and is being funded
primarily through a reallocation of resources from discretionary projects.
Therefore, the Year 2000 project is not expected to result in any significant
incremental technology cost and is not expected to have a material effect on the
results of operations. Through September 30, 1998, the Company and its
subsidiaries and affiliates have incurred and expensed approximately $47 million
related to the assessment of, and preliminary efforts in connection with, the
project and the development of a remediation plan. The total remaining cost of
the project is estimated at between $30-40 million.
 
The costs of the project and the date on which the Company plans to complete the
Year 2000 modifications are based on management's best estimates, which were
derived utilizing numerous assumptions of future events including the continued
availability of certain resources, third party modification plans and other
factors. However, there can be no guarantee that these estimates will be
achieved and actual results could differ materially from those plans. Specific
factors that might cause such material differences include, but are not limited
to, the availability and cost of personnel trained in this area, the ability to
locate and correct all relevant computer codes, and similar uncertainties.

                                   APPENDIX A
                    MORE INFORMATION ABOUT THE FIXED ACCOUNT
 
Because of exemption and exclusionary provisions in the securities laws,
interests in the Fixed Account are not generally subject to regulation under the
provisions of the Securities Act of 1933 or the Investment Company Act of 1940.
Disclosures regarding the fixed portion of the annuity contract and the Fixed
Account may be subject to the provisions of the Securities Act of 1933
concerning the accuracy and completeness of statements made in this Prospectus.
The disclosures in this APPENDIX A have not been reviewed by the Securities and
Exchange Commission.
 
The Fixed Account is part of the Company's General Account and is made up of all
of the general assets of the Company other than those allocated to a separate
account. Allocations to the Fixed Account become part of the assets of the
Company and are used to support insurance and annuity obligations. A portion or
all of net payments may be allocated to accumulate at a fixed rate of interest
in the Fixed Account. Such net amounts are guaranteed by the Company as to
principal and a minimum rate of interest. Under the Contract, the minimum
interest which may be credited on amounts allocated to the Fixed Account is 3%
compounded annually. Additional "Excess Interest" may or may not be credited at
the sole discretion of the Company.
 
To the extent permitted by state law, the Company reserves the right, from time
to time, to credit an enhanced interest rate to certain initial and/or
subsequent payments ("eligible payments") which are deposited into the Fixed
Account under an Automatic Transfer Option (Dollar Cost Averaging election) that
uses the Fixed Account as the source account from which automatic transfers are
then processed. The following are not considered eligible payments: amounts
transferred into the Fixed Account from the Variable Account and/or the
Guarantee Period Accounts; amounts already in the Fixed Account at the time an
eligible payment is deposited and amounts transferred to the Contract from
another annuity contract issued by the Company.
 
An eligible payment must be automatically transferred out of the Fixed Account
over a continuous six month period. The enhanced rate will apply during the six
month period to any portion of the eligible payment remaining in the Fixed
Account. Amounts automatically transferred out of the Fixed Account will no
longer earn the enhanced rate of interest and, as of the date of transfer, will
be subject to the variable investment performance of the sub-account(s)
transferred into. If the automatic transfer option is terminated prior to the
end of the six month period, the enhanced rate will no longer apply. The Company
reserves the right to extend the period of time that the enhanced rate will
apply.

                          THE MARKET VALUE ADJUSTMENT
 
MARKET VALUE ADJUSTMENT -- The following are examples of how the market value
adjustment works:
 
The market value factor is: [(1+i)/(1+j)]n/365-1
 
    The following examples assume:
 
     1. The payment was allocated to a ten-year Guarantee Period Account with a
       Guaranteed Interest Rate of 8%.
 
     2. The date of surrender is seven years (2,555 days) from the expiration
       date.
 
     3. The value of the Guarantee Period Account is equal to $62,985.60 at the
       end of three years.
 
     4. No transfers or withdrawals affecting this Guarantee Period Account have
       been made.
 
NEGATIVE MARKET VALUE ADJUSTMENT (UNCAPPED)
 
    Assume that on the date of surrender, the current rate (j) is 10.00% or 0.10
