* From time to time the Company may allow a reduction of the surrender charge,
the period during which the charges apply, or both, and/or credit additional
amounts on Contracts when (1) Contracts are sold to individuals or groups of
individuals in a manner which reduces sales expenses, or (2) where the Owner or
the Annuitant on the date of issue is within certain classes of eligible
persons. For more information, see "REDUCTION OR ELIMINATION OF SURRENDER CHARGE

(3) ANNUAL UNDERLYING FUND EXPENSES:
    
In addition to the charges described above, certain fees and expenses are
deducted from the assets of the Underlying Funds. The levels of fees and
expenses vary among the Funds. For more information concerning fees and
expenses, see the prospectuses of the Funds.
 
   
The following table gives certain fee and expense information for the Funds for
1998. However, a performance-based management fee is provided for under the
Management Agreements for the Portfolios of The Fulcrum Trust (the
"Portfolios"). The base fee is 2.00%, but the actual fee may vary from between
0.00% to 4.00%, depending on a Portfolio's performance. Because of the
possibility of wide variations in the management fees from year-to-year,
hypothetical expense information assuming fees of 0.00%, 2.00% and 4.00%, is
shown below under "MORE INFORMATION ABOUT PERFORMANCE FEES OF THE FULCRUM
TRUST."

(1) A performance based advisory fee is in effect, which fee may vary anywhere
from 0.00% to 4.00%.
 
   
(2) These numbers have been restated to reflect the expense limitations in
effect during 1999. (Different expense limitations were in effect during 1998.)
AFIMS has voluntarily agreed to limit operating expenses and reimburse those
expenses to the extent that the Portfolio's "Other Expenses" during 1999 (i.e.,
expenses other than management fees) exceed the following expense limitations
(expressed as an annualized percentage of average daily net assets): 1.50% for
the Global Interactive/Telecomm Portfolio, 1.50% for the International Growth
Portfolio, 1.20% for the Growth Portfolio, 1.20% for the Value Portfolio, and
1.50% for the Strategic Income Portfolio. These limitations are in effect
through December 31, 1999. Without the effect of the expense limitations, the
1998 "Other Expenses" ratios would have been the following: 3.69% for the Global
Interactive/Telecomm Portfolio, 5.09% for the International Growth Portfolio,
5.04% for the Growth Portfolio, 3.00% for the Value Portfolio, and 6.49% for the
Strategic Income Portfolio.
    
 
   
(3) Effective August 1, 1998, a new Portfolio Manager, Analytic Investors, Inc.,
is in place for the Growth Portfolio. The Manager and the Portfolio Manager have
voluntarily agreed to limit their fee from August 1, 1998 through July 31, 1999
to the lesser of the following two rates: (1) 0.80%, the rate specified in the
Portfolio Manager Agreement; or (2) the rate that would have applied under the
prior Portfolio Manager Agreement with the prior portfolio manager. The latter
rate varies based on prior performance.

(4) Under the Management Agreement with Allmerica Investment Trust, AFIMS has
declared a voluntary expense limitation of 0.60% for the Money Market Fund, but
the expenses of the Money Market Fund did not exceed the cap in 1998.The
limitation may be terminated at any time.
    
 
   
(5) Effective May 1, 1999 through October 31, 1999, Delaware Management Company
has voluntarily agreed to waive its management fees and reimburse Small Cap
Value Series and Delaware Balanced Series for expenses in order that Total Fund
Expenses will not exceed 0.85% and 0.80%, respectively. The fee ratios shown
above have been restated, as necessary, to reflect changes in expense
limitations effective May 1, 1999. The declaration of a voluntary expense
limitation does not bind the investment adviser to declare future expense
limitations with respect to these series. Pursuant to a vote of the Fund's
shareholders on March 17, 1999, a new management fee structure based on average
daily net assets was approved. The above ratios have been restated to reflect
the new management fee structure which took effect on May 1, 1999.
    
 
   
(6) Lazard Asset Management, the Portfolio's investment advisor, has voluntarily
agreed to waive its fees and reimburse the Lazard Retirement International
Equity Portfolio if total operating expenses exceed 1.25% of average net assets.
Total portfolio operating expenses prior to waivers and/or reimbursements by the
investment advisor, total 48.67%, annualized, at December 31, 1998.
    
 
(7) Other Expenses for the Lazard Retirement International Equity Portfolio
include a 12b-1 fee which is deducted from Portfolio assets at a maximum annual
rate of 0.25% of the average daily value of the Portfolio's net assets. A
portion or all of the 12b-1 fee may be used to reimburse the Company for certain
administrative and distribution support services provided to the Lazard
Retirement International Equity Portfolio.
 
   
(8) Other Expenses are based on amounts for the fiscal year ended December 31,
1998. The adviser to PBHG Select 20 Portfolio has agreed to waive or limit the
management fees and to assume other expenses of the portfolio to the extent
necessary to limit the Total Fund Expenses to not more than 1.20% of the average
daily net assets of the portfolio. Absent such fee waivers/expense
reimbursements, the Management Fees, Other Expenses and Total Fund Expenses for
the PBHG Select 20 Portfolio were 0.85%, 0.36% and 1.21%, respectively.
    
 
   
The Underlying Fund information above was provided by the Underlying Funds and
was not independently verified by the Company.
    
 
   
EXPENSE EXAMPLES  The following examples demonstrate the cumulative expenses
which an Owner would pay at 1, 3, 5, and 10-year intervals, assuming the 1998
expenses set forth above, a $1,000 investment in a Sub-Account and a 5% annual
return on assets. As required by rules of the Securities and Exchange Commission
("SEC"), the Contract fee is reflected in the examples by a method designed to
show the "average" impact on an investment in the Variable Account. The total
Contract fees collected 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 $100,000. Lower costs
apply to Contracts issued to a 401(k) plan.

MORE INFORMATION ABOUT PERFORMANCE FEES OF THE FULCRUM TRUST
 
   
The tables below show the expenses of the Portfolios of The Fulcrum Trust as if
the Portfolios paid performance based management fees of 0.00%, 2.00%, and
4.00%, respectively.
    
 
   
A performance-based management fee is currently in effect for the Portfolios of
The Fulcrum Trust, other than the Growth Portfolio. The base fee is 2.00%, but
the actual fee may vary from between 0.00% to 4.00%, depending on the
Portfolio's performance. The base fee of 2.00% will be paid if the Portfolio's
performance (net of all fees and expenses, including the management fee) is
between 1.5 and 3.0 percentage points higher than the applicable benchmark
index. A fee of 4.00% will be paid only if the Portfolio's performance (net of
all fees and expenses, including the management fee) is at least 7.5 percentage
points higher than the applicable benchmark index. No fee will apply if the
Portfolio's performance is more than 3.0 percentage points lower than the
applicable benchmark index; see the prospectus of The Fulcrum Trust for more
details. Because of this variation, expense information assuming fees of 0.00%,
2.00% and 4.00% is shown below. The fee, however, could be any figure between
0.00% and 4.00%. In 1998, the actual management fees were 1.96% for the Global
Interactive/Telecomm Portfolio, 0.05% for the International Growth Portfolio,
0.00% for the Growth Portfolio, 0.30% for the Value Portfolio and 0.47% for the
Strategic Income Portfolio.
    
 
   
For the first 12 full calendar months after a new Portfolio Manager is hired
(or, in the case of a Portfolio that had only one Portfolio Manager, for the
first 12 full calendar months of operations), the advisory agreement sets the
management fee at an annual rate of 0.80% of the Portfolio's average daily net
assets. As of the date of this prospectus, this initial fee is relevant for only
one Portfolio -- the Growth Portfolio. Effective August 1, 1998, a new Portfolio
Manager, Analytic Investors, Inc. ("Analytic"), is in place for the Growth
Portfolio. The Manager and the Portfolio Manager have voluntarily agreed to
limit their fee from August 1, 1998 through July 31, 1999 to the lesser of the
following two rates: (1) 0.80%, the rate specified in the Portfolio Manager
Agreement; or (2) the rate that would have applied under the prior Portfolio
Manager Agreement with the prior portfolio manager. The latter rate varies based
on prior performance. For more information, see Footnotes 3 and 4, below, and
the prospectus for The Fulcrum Trust.
    
 
   
EXAMPLE 1 -- ASSUMING ADVISORY FEE OF 0.00% FOR THE PORTFOLIOS OF THE FULCRUM
  TRUST.
    
 
(For the fee to be 0.00% a Portfolio's performance, net of all fees and
expenses, would have to be more than 3.0 percentage points below the benchmark
index.)

(1) A performance based advisory fee is in effect, which fee may vary anywhere
from 0.00% to 4.00%.
 
   
(2) AFIMS has voluntarily agreed to limit operating expenses and reimburse those
expenses to the extent that the Portfolio's "Other Expenses" during 1999 (i.e.,
expenses other than management fees) exceed the following expense limitations
(expressed as an annualized percentage of average daily net assets): 1.50% for
the Global Interactive/Telecomm Portfolio, 1.50% for the International Growth
Portfolio, 1.20% for the Growth Portfolio, 1.20% for the Value Portfolio, and
1.50% for the Strategic Income Portfolio. There were different expense
limitations in effect during 1998. The limitations are in effect through
December 31, 1999. Without the effect of the expense limitations, the 1998
"Other Expenses" ratios would have been the following: 3.69% for the Global
Interactive/Telecomm Portfolio, 5.09% for the International Growth Portfolio,
5.04% for the Growth Portfolio, 3.00% for the Value Portfolio, and 6.49% for the
Strategic Income Portfolio.
    
 
   
(3) Under the Management Agreement with Allmerica Investment Trust, AFIMS has
declared a voluntary expense limitation of 0.60% for the Money Market Fund, but
the expenses of the Money Market Fund did not exceed the cap in 1998. The
limitation may be terminated at any time.
    
 
   
(4) Effective August 1, 1998, a new Portfolio Manager, Analytic Investors, Inc.,
is in place for the Growth Portfolio. The Manager and the Portfolio Manager have
voluntarily agreed to limit their fee from August 1, 1998 through July 31, 1999
to the lesser of the following two rates: (1) 0.80%, the rate specified in the
Portfolio Manager Agreement; or (2) the rate that would have applied under the
prior Portfolio Manager Agreement with the prior portfolio manager. The latter
rate varies based on prior performance.

EXAMPLES BASED ON HYPOTHETICAL PERFORMANCE FEES OF THE PORTFOLIOS OF THE FULCRUM
  TRUST.
 
   
The information given under the following hypothetical examples should not be
considered a representation of past or future expenses. Actual expenses may be
greater or lesser than those shown. In particular, because the advisory fee of
the five Portfolios of The Fulcrum Trust may vary from 0.00% to 4.00% depending
on performance, three separate examples are provided: Example (1) assumes that
no advisory fee is paid for each of the five Portfolios; Example (2) assumes
that the advisory fee for the five Portfolios is paid at the annual rate of
2.00%; and Example (3) assumes that the advisory fee is paid at the annual rate
of 4.00%.

(1) In order to have a 5% annual return and a management fee of 4%, the
performance of the Portfolios of The Fulcrum Trust would have to be 9% before
the deduction of the 4% fee resulting in performance of 5% and the benchmark
index would have to decrease at least 2.5 percentage points (meaning the
Portfolio's performance after fees and expenses was at least 7.5 percentage
points better than the benchmark index.)
    
 
As required in rules promulgated under the Investment Company Act of 1940 (the
"1940 Act"), the Contract fee is reflected in the examples by a method to show
the "average" impact on an investment in the Variable Account. The total
Contract fees collected 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 $100,000. Lower costs
apply to Contracts issued to a 401(k) plan.
 
   
* The Contract fee is not deducted after annuitization. No surrender charge is
assessed at the time of annuitization under an option including a life
contingency or under a noncommutable period certain option of ten years or
longer.

                          SUMMARY OF CONTRACT FEATURES
    
 
WHAT IS THE FULCRUM FUND VARIABLE ANNUITY?
 
   
The Fulcrum Fund Variable Annuity contract ("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 who are paid on an incentive fee
   basis;
 
- -  tax deferral on earnings;
 
- -  guarantees that can protect your family during the accumulation phase;
 
   
- -  income payments that you can receive for life;
    
 
- -  issue age up to your 90th birthday.
 
   
he Contract has two phases: an accumulation phase and, if you choose to
annuitize, an annuity payout phase. During the accumulation phase, you may
allocate your initial payment and any additional payments you choose to make
among the Sub-Accounts investing in the portfolios of securities (the
"Underlying Funds"), 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. Your Contract's Accumulated Value is based on the investment
performance of the Funds and any accumulations in the Guarantee Period and Fixed
Accounts. No income taxes are paid on any earnings under the Contract unless you
withdraw money. In addition, during the accumulation phase, your beneficiaries
receive certain protections and guarantees in the event of the Annuitant's
death. See discussion below: "WHAT HAPPENS UPON DEATH DURING THE ACCUMULATION
PHASE?"
    
 
WHAT HAPPENS IN THE ANNUITY PAYOUT PHASE?
 
   
During the annuity payout phase, the Annuitant 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
Funds, fixed-amount annuity benefit payments with payment amounts guaranteed by
the Company, or a combination of fixed-amount and variable annuity benefit
payments. Among the payout options available during the annuity payout phase
are:
    
 
- -  periodic payments for your lifetime (assuming you are the Annuitant);
 
- -  periodic payments for your life and the life of another person selected by
   you;
 
   
- -  periodic payments for your lifetime with any remaining guaranteed payments
   continuing to your beneficiary for ten years in the event that you die 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.
 
                                       15
<PAGE>
   
An optional Minimum Guaranteed Annuity Payout Rider is available during the
accumulation phase in most jurisdictions for a separate monthly charge. See "M.
Optional Minimum Guaranteed Annuity Payout Rider" under "Description of the
Contract." If elected, the Rider guarantees the Annuitant a minimum amount of
fixed lifetime income during the annuity payout phase, subject to certain
conditions. On each Contract anniversary a Minimum Guaranteed Annuity Payout
Benefit Base is determined. The Minimum Guaranteed Annuity Payout Benefit Base
(less any applicable premium taxes) is the value that will be annuitized should
you exercise the Rider. In order to exercise the Rider, a fixed annuitization
option involving a life contingency must be selected. Annuitization under this
Rider will occur at the guaranteed annuity purchase rates listed under the
Annuity Option Tables in your Contract. The Minimum Guaranteed Annuity Payout
Benefit Base is equal to the greatest of:
    
 
   
(a) the Accumulated Value increased by any positive Market Value Adjustment, if
    applicable; or
    
 
   
(b) the Accumulated Value on the effective date of the Rider compounded daily at
    the annual rate of 5% plus gross payments made thereafter compounded daily
    at the annual rate of 5%, starting on the date each payment is applied,
    reduced proportionately to reflect withdrawals; or
    
 
   
(c) the highest Accumulated Value on any Contract anniversary since the Rider
    effective date, as determined after positive adjustments have been made for
    subsequent payments and any positive Market Value Adjustment, if applicable,
    and negative adjustments have been made for subsequent withdrawals.
    
 
   
For each withdrawal described in (b) and (c) above, the proportionate reduction
is calculated by multiplying the (b) or (c) value, whichever is applicable,
determined immediately prior to the withdrawal by the following fraction:
    
 
   
                            amount of the withdrawal
           ----------------------------------------------------------
        Accumulated Value determined immediately prior to the withdrawal
    
 
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 all jurisdictions except
Hawaii and New York) or 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 the Annuitant), an
Annuitant and one or more beneficiaries. As Owner, you make payments, choose
investment allocations and select the Annuitant and beneficiary. The Annuitant
is the individual who receives annuity benefit payments under the Contract. The
beneficiary is the person who receives any payment on the death of the Owner or
Annuitant.
    
 
HOW MUCH CAN I INVEST AND HOW OFTEN?
 
The number and frequency of payments are flexible, subject to the minimum and
maximum payments stated in "A. Payments."
 
WHAT ARE MY INVESTMENT CHOICES?
 
   
You may allocate payments among the Sub-Accounts investing in the following
Funds, the Guarantee Period Accounts, and the Fixed Account. You have a choice

This range of investment choices enables you to allocate your money among the
Funds to meet your particular investment needs. For a more detailed description
of the Funds, see "INVESTMENT OBJECTIVES AND POLICIES."
 
   
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, except in California where assets are held in the
Company's General 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
    
 
                                       17
<PAGE>
of the Guaranteed Interest Rate depends on the number of years of the Guarantee
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. 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 is
guaranteed for one year from that date. For more information about the Fixed
Account, see APPENDIX A, "MORE INFORMATION ABOUT THE FIXED ACCOUNT."

For more information, see "DESCRIPTION OF THE COMPANIES, THE VARIABLE ACCOUNTS
AND THE UNDERLYING FUNDS."
    
 
   
CAN I MAKE TRANSFERS AMONG THE ACCOUNTS?
    
 
   
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 for processing these transfers.
    
 
WHAT IF I NEED MY MONEY BEFORE MY ANNUITY PAYOUT PHASE BEGINS?
 
   
You may surrender your Contract or make withdrawals any time before your annuity
payout phase begins. Each year you can take without a surrender charge the
greatest of 100% of cumulative earnings, 15% of the
    
 
                                       18
<PAGE>
   
Contract's Accumulated Value or, if you are both an Owner and the Annuitant, an
amount based on your life expectancy. (Similarly, no surrender charge will apply
if an amount is withdrawn based on the Annuitant's life expectancy if the Owner
is a trust or other nonnatural person.) A 10% tax penalty may apply to amounts
deemed to be income if you are under age 59 1/2. Additional amounts may be
withdrawn at any time but payments that have not been invested in the Contract
for more than seven years may be subject to a surrender charge. (A Market Value
Adjustment, which may increase or decrease the value of your account, may apply
to any withdrawal made from a Guarantee Period Account prior to the expiration
of the Guarantee Period.)
    
 
   
In addition, you may withdraw all or a portion of your money without a surrender
charge if, after the Contract is issued and before age 65, you become disabled.
Also, except in New York and New Jersey where not permitted by state law, you
may withdraw money without a surrender charge if, after the Contract is issued,
you are admitted to a medical care facility or diagnosed with a fatal illness.
For details and restrictions, see "Reduction or Elimination of Surrender Charge
and Additional Amounts Credited."
    
 
WHAT HAPPENS UPON DEATH DURING THE ACCUMULATION PHASE?
 
If the Annuitant, Owner or Joint Owner should die before the Annuity Date, a
death benefit will be paid to the beneficiary. Upon the death of the Annuitant
(or an Owner who is also an Annuitant), the death benefit is equal to the
greatest of:
 
- -  The Accumulated Value increased by any positive Market Value Adjustment;
 
   
- -  Gross payments, compounded daily at the annual rate of 5% (5% compounding not
   available in Hawaii and New York), decreased proportionately to reflect
   withdrawals; or
    
 
- -  The death benefit that would have been payable on the most recent Contract
   anniversary, increased for subsequent payments and decreased proportionately
   for subsequent withdrawals.
 
   
This guaranteed death benefit works in the following way assuming no withdrawals
are made. On the first anniversary, the death benefit will be equal to the
greater of (a) the Accumulated Value (increased by any positive Market Value
Adjustment) or (b) gross payments compounded daily at the annual rate of 5%
(except in Hawaii and New York where (b) equals gross payments). The higher of
(a) or (b) will then be locked in until the second anniversary, at which time
the death benefit will be equal to the greatest of (a) the Contract's then
current Accumulated Value increased by any positive Market Value Adjustment; (b)
gross payments compounded daily at the annual rate of 5% (gross payments in
Hawaii and New York) or (c) the locked-in value of the death benefit at the
first anniversary. The greatest of (a), (b) or (c) will be locked in until the
next Contract anniversary. This calculation will then be repeated on each
anniversary while the Contract remains in force and prior to the Annuity Date.
As noted above, the values of (b) and (c) will be decreased proportionately if
withdrawals are taken.
    
 
If an Owner who is not also the Annuitant dies during the accumulation phase,
the death benefit will equal the Accumulated Value of the Contract increased by
any positive Market Value Adjustment.
 
(If the Annuitant dies after the Annuity Date but before all guaranteed annuity
benefit payments have been made, the remaining payments will be paid to the
beneficiary at least as rapidly as under the annuity option in effect. See "G.
Death Benefit.")
 
WHAT CHARGES WILL I INCUR UNDER MY CONTRACT?
 
   
If the Accumulated Value is less than $100,000 on each Contract anniversary and
upon surrender, the Company will deduct a $30 Contract fee from the Contract.
The Contract fee is waived for Contracts issued to and maintained by a trustee
of a 401(k) plan.
    
 
                                       19
<PAGE>
   
Should you decide to surrender the Contract, make withdrawals, or receive
payments under certain annuity payout options, you may be subject to a surrender
charge. If applicable, this charge will be between 1% and 7% of payments
withdrawn, based on when the payments were originally made.
    
 
A deduction for state and local premium taxes, if any, may be made as described
under "C. Premium Taxes."
 
   
The Company will deduct, on a daily basis, an annual Mortality and Expense Risk
Charge and Administrative Expense Charge equal to 1.25% and 0.20%, respectively,
of the average daily net assets invested in each Underlying Fund. The Funds will
incur certain management fees and expenses which are more fully described in
"Other Charges" and in the prospectuses of the Underlying Funds, which accompany
this Prospectus.
    
 
   
Subject to state availability, the Company offers the following optional Rider
that may be elected by the Owner. A separate monthly charge is made for the
Rider which is deducted from the Accumulated Value at the end of each month
within which the Rider has been in effect. The applicable charge is assessed by
multiplying the Accumulated Value on the last day of each month and on the date
the Rider is terminated by 1/12th of the following annual percentage rates:
    
 
   
    Minimum Guaranteed Annuity Payout Rider with a ten-year waiting
    period.                                                            0.25%
    Minimum Guaranteed Annuity Payout Rider with a fifteen-year waiting
    period.                                                            0.15%
    
 
   
For a description of this Rider, see "C. Optional Minimum Guaranteed Annuity
Payout Rider Charge" under "CHARGES AND DEDUCTIONS," and "M. Optional Minimum
Guaranteed Annuity Payout Rider" under "DESCRIPTION OF THE CONTRACT."
    
 
CAN I EXAMINE THE CONTRACT?
 
   
Yes. Your 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 your 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."
    
 
CAN I MAKE FUTURE CHANGES UNDER MY CONTRACT?
 
   
You can make several changes after receiving the Contract:

                            PERFORMANCE INFORMATION
 
   
This Contract first was offered to the public in 1997. The Company, however, may
advertise "total return" and "average annual total return" performance
information based on (1) the periods that the Sub-Accounts have been in
existence and (2) the periods that the Underlying Funds have been in existence.
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 Fund 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 Fund other than the Money Market Fund
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 for the periods that the Sub-Accounts
have been in existence 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 1.45%, the Underlying Fund charges, the $30
annual Contract fee and the surrender charge which would be assessed if the
investment were completely withdrawn at the end of the specified period. The
calculation is not adjusted to reflect the deduction of the optional Minimum
Guaranteed Annuity Payout Rider charge. Quotations of supplemental average total
returns for the periods that the Sub-Accounts have been in existence are
calculated in exactly the same manner and for the same periods of time except
that it does not reflect the Contract fee and assumes that the Contract is not
surrendered at the end of the periods shown.
    
 
Additional performance may also be shown calculated in exactly the same manner
as described above, however, the period of time may be based on the Underlying
Fund's lifetime, which may predate the Sub-Account's inception date. These
performance calculations are based on the assumption that the Sub-Account
corresponding to the applicable Underlying Fund 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 and performance numbers, 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
 
                                       21
<PAGE>
INFORMATION SHOULD BE CONSIDERED IN LIGHT OF THE INVESTMENT OBJECTIVES AND
POLICIES AND RISK CHARACTERISTICS OF THE UNDERLYING FUND 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, Inc., 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. In addition, relevant broad-based indices and performance from
independent sources may be used to illustrate the performance of certain
contract features.
    
 
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 Funds.

                              THE UNDERLYING FUNDS

under the laws of Massachusetts in 1844, is among the five oldest life insurance
companies in America. As of December 31, 1998, First Allmerica and its
subsidiaries had over $27 billion in combined assets and over $48 billion of

THE VARIABLE ACCOUNTS.  Each Company maintains a separate account called the
Fulcrum Separate Account (the "Variable Account"). The Variable Accounts were
authorized by votes of the Board of Directors of the Companies on June 13, 1996.
Each Variable Account meets the definition of a "separate account" under federal
securities laws and is registered with the SEC as a unit investment trust under
the 1940 Act. This registration does not involve the supervision or management
of investment practices or policies of the Variable Accounts by the SEC.
    
 
   
The Fulcrum Separate Account is a separate investment account of the Company
with fifteen Sub-Accounts. The assets used to fund the variable portions of the
Contracts are set aside in Sub-Accounts kept separate from the general assets of
the Company. Each Sub-Account is administered and accounted for as part of the
general business of the Company. The income, capital gains, or capital losses of
each Sub-Account, however, are allocated to each Sub-Account, without regard to
any other income, capital gains, or capital losses of the Company. Under
Delaware and Massachusetts law, the assets of the Variable Account may not be
charged with any liabilities arising out of any other business of the Company.
    
 
The Company reserves the right, subject to compliance with applicable law, to
change the names of the Variable Account and the Sub-Accounts.
 
   
THE FULCRUM TRUST.  The Fulcrum Trust (previously known as the Palladian-SM-
Trust) was established as a Massachusetts business trust on September 8, 1993,
and is registered with the SEC as a management investment company. Five
investment portfolios of The Fulcrum Trust (the "Portfolios") are currently
available under the Contract.
    
 
Allmerica Financial Investment Management Services, Inc. ("AFIMS") serves as
overall manager of The Fulcrum Trust and is responsible for general investment
supervisory services to the Portfolios. The Fulcrum Trust and AFIMS have
retained several Portfolio Managers to manage the assets of each Portfolio.
AFIMS is located at 440 Lincoln Street, Worcester, MA 01653.
 
The five Portfolios of The Fulcrum Trust and their respective Portfolio Managers
are as follows:

</TABLE>
    
 
Allmerica Asset Management, Inc. ("AAM") is an affiliate of the Company and of
AFIMS. The other Portfolio Managers are not affiliated with the Company or with
AFIMS.
 
The Fulcrum Trust currently pays AFIMS and the Portfolio Managers a monthly fee
(the "management fee") based on the average daily net assets of each Portfolio.
For the first year that a new Portfolio Manager is hired (or, in the case of a
Portfolio that has had only one Portfolio Manager, for the first year of
operations) the
 
                                       23
<PAGE>
   
advisory fee is set at an annual rate of 0.80% of the Portfolio's average daily
net assets. After the twelfth full calendar month has elapsed, the
performance-based fee will be in effect. As of the date of this prospectus, this
first year fee arrangement is in effect for only one Portfolio- the Growth
Portfolio. Effective August 1, 1998, a new Portfolio Manager, Analytic
Investors, Inc. ("Analytic"), is in place for the Growth Portfolio. The Manager
and the Portfolio Manager have voluntarily agreed to limit their fee from August
1, 1998 through July 31, 1999 to the lesser of the following two rates: (1)
0.80%, the rate specified in the Portfolio Manager Agreement; or (2) the rate
that would have applied under the prior Portfolio Manager Agreement with the
prior portfolio manager. The latter rate varies based on prior performance.
    
 
Other than for the Growth Portfolio, each Portfolio Manager is currently paid on
an incentive fee basis, which could result in either higher than average
management fees or, possibly, no management fee at all, depending on how well
each Portfolio Manager performs. There are two components to the management fee:
the basic fee and the incentive fee. The management fee is structured to vary
based upon the Portfolio's performance (after expenses) compared to that of an
appropriate market benchmark selected for that Portfolio. The management fee
schedule provides for an incentive performance fee for superior performance, and
provides for lower fee for sub-par performance. The base fee is 2.00%, but may
vary from 0.00% to 4.00% depending on the Portfolio's performance.
 
ALLMERICA INVESTMENT TRUST.  Allmerica Investment Trust is an open-end,
diversified, management investment company registered with the SEC under the
1940 Act.
 
Allmerica Investment Trust was established as a Massachusetts business trust on
October 11, 1984, for the purpose of providing a vehicle for the investment of
assets of various variable accounts established by the Company or other
insurance companies. The Money Market Fund of Allmerica Investment Trust is
available under the Contract; certain other funds of Allmerica Investment Trust
are not currently offered under the Contract. Shares of the Trust are not
offered to the general public but solely to such variable accounts.
 
AFIMS is the investment manager of Allmerica Investment Trust and, subject to
the direction of the Board of Trustees, handles the day-to-day affairs of the
Trust. AFIMS has entered into a Sub-Adviser Agreement with its affiliate, AAM,
for investment management services for the Money Market Fund. Under the
Sub-Adviser Agreement, AAM is authorized to engage in portfolio transactions on
behalf of the Money Market Fund, subject to such general or specific
instructions as may be given by the Trustees. Both AFIMS and AAM are located at
440 Lincoln Street, Worcester, Massachusetts 01653.
 
For providing its services under the Management Agreement, AFIMS will receive a
fee, computed daily at an annual rate based on the average daily net asset value
of the Money Market Fund as follows: 0.35% on net asset value up to $50,000,000;
0.25% on the next $200,000,000; and 0.20% on the remainder. The fee is paid from
the assets of the Money Market Fund. AFIMS is solely responsible for the payment
of all fees for investment management services to AAM, which will be a fee of
0.10%, computed daily at an annual rate based on the average daily net asset
value of the Money Market Fund.

                                       26
<PAGE>
without charge to another Fund or to the Fixed Account or a Guarantee Period
Account, where available, on written request received by the Company within 60
days of the later of (1) the effective date of such change in the investment
policy, or (2) the receipt of the notice of the Owner's right to transfer.
 
                          DESCRIPTION OF THE CONTRACT
 
A.  PAYMENTS
 
   
The Company issues a Contract when its underwriting requirements, which include
receipt of the initial payment and allocation instructions by the Company at its
Principal Office are met. 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 annuity 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 is 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 completed within five business days of the Company's
receipt of the initial payment, the payment will be returned immediately unless
the Owner specifically consents to the holding of it pending completion of the
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 may be made to the Contract at any time prior to the Annuity Date.
Currently, the initial payment must be at least $25,000. Under a salary
deduction or monthly automatic payment plan, the minimum initial payment is $50.
In all cases, each subsequent payment must be at least $50. Where the
contribution on behalf of an employee under an employer-sponsored retirement
plan is less than $600 but more than $300 annually, the Company may issue a
contract on the employee, if the plan's average annual contribution per eligible
plan participant is at least $600. 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
Fund.
    
 
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 may include requirements that callers on behalf of the Owner identify
themselves by name and identify the Annuitant by name, date of birth and social
security number or PIN 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 representative through whom the Contract was purchased, to the
Principal Office at 440 Lincoln Street, Worcester, MA 01653, or to any local
office of the Company. Mailing or delivery must occur on or before ten days
after receipt of the Contract for cancellation to be effective.
    
 
                                       27
<PAGE>
Within seven days the Company will provide a refund equal to the greater of (1)
gross payments, or (2) the Accumulated Value plus any amounts deducted under the
Contract or by the Funds for taxes, charges or fees.
 
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. In most
states, the Company will pay the Owner an amount equal to the sum of (1) the
difference between the payment received, 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
will be used. 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.
    
 
   
In order to comply with New York regulations concerning the purchase of a new
annuity contract to replace an existing life or annuity contract (a
"replacement"), an Owner who purchases the Contract in New York as a replacement
may cancel within 60 days after receipt. In order to cancel the Contract, the
Owner must mail or deliver it to the Company's Principal Office or to one of its
authorized representatives. The Company will refund an amount equal to the
Surrender Value plus all fees and charges and the Contract will be void from the
beginning.
    
 
D.  TRANSFER PRIVILEGE
 
   
At any time prior to the Annuity Date, the Owner may transfer amounts among
accounts upon written or telephone request to the Company. As of the date of
this Prospectus, transfers may be made to and among all of the available
Sub-Accounts. However, should additional Funds be added to the Contract, the
Company reserves the right to limit the number of Sub-Accounts which may be used
during the life of the Contract. As discussed in "A. Payments" above, a properly
completed authorization form must be on file before telephone requests will be
honored. Transfer values will be effected at the Accumulation Value next
computed after receipt of the transfer order. In Oregon and Massachusetts,
payments and transfers to the Fixed Account are subject to certain restrictions.
See APPENDIX A, "MORE INFORMATION ABOUT THE FIXED ACCOUNT."
    
 
   
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 Sub-Account which invests in the Money Market
Fund. Transfers from a Guarantee Period Account prior to the expiration of the
Guarantee Period will be subject to a Market Value Adjustment.
    
 
   
The first 12 transfers in a Contract year are guaranteed to be free of any
transfer charge. The Company does not currently charge for additional transfers
but reserves the right to assess a charge, guaranteed never to exceed $25, to
reimburse it for the expense of processing these additional transfers.
    
 
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 Strategic Income Portfolio, Money Market
Fund or the Fixed Account (the "source account") to one or more Funds. Automatic
transfers may not be made into the Fixed Account, the Guarantee Period Accounts
or, if applicable, the Fund 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 Funds.
Automatic transfers will continue until
 
                                       28
<PAGE>
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.
 
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 transfer. 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
percentage allocations specified by the Owner. As frequently as specified by the
Owner, the Company will review the percentage allocations in the Funds 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. 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. As such,
subsequent payment 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 Funds 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 effected in a Contract year under a request
count as one transfer for purposes of the 12 transfers guaranteed to be free of
a transfer charge in each Contract year. Currently, Dollar Cost Averaging and
Automatic Account Rebalancing may not be in effect simultaneously. Either option
may be elected at no additional charge when the Contract is purchased or at a
later date.
    
 
E.  SURRENDER
 
   
At any time prior to the Annuity Date, the Owner may surrender the Contract and
receive its Accumulated Value, less applicable charges and adjusted for any
Market Value Adjustment ("Surrender Amount"). The Owner must return the Contract
and a signed, written request for surrender, satisfactory to the Company, to the
Principal Office. The Surrender Value will be calculated 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.
    
 
   
Before the Annuity Date, a surrender charge may be deducted when a Contract is
surrendered if payments have been credited to the Contract during the last seven
full Contract years. See "CHARGES AND DEDUCTIONS." The Contract fee will be
deducted upon surrender of the Contract.
    
 
   
After the Annuity Date, only Contracts annuitized under a commutable period
certain option may be surrendered. The amount payable is the commuted value of
any unpaid installments, computed on the basis of the assumed interest rate
incorporated in such annuity benefit payments. No surrender charge is imposed
after the Annuity Date.
    
 
Any amount surrendered is normally 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 each separate account is not reasonably
practicable.
 
                                       29
<PAGE>
   
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.
    
 
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."
 
For important tax consequences which may result from surrender, see "FEDERAL TAX
CONSIDERATIONS."
 
F.  WITHDRAWALS
 
   
At any time prior to the Annuity Date, an Owner may withdraw a portion of the
Accumulated Value of his or her Contract, subject to the limits stated below.
The Owner must submit a signed, written request for withdrawal, satisfactory to
the Company, to the Principal Office. The written request must indicate the
dollar amount the Owner wishes to receive and the accounts from which such
amount is to be withdrawn. The amount withdrawn equals the amount requested by
the Owner plus any applicable surrender charge, as described under "CHARGES AND
DEDUCTIONS." In addition, amounts withdrawn from a Guarantee Period Account
prior to the end of the applicable Guarantee Period will be subject to a Market
Value Adjustment, 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. Except in New York where no
specific balance is required, 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."
    
 
After the Annuity Date, only Contracts under which future variable annuity
benefit payments are limited to a specified period may be withdrawn. A
withdrawal after the Annuity Date will result in cancellation of a number of
Annuity Units equivalent in value to the amount withdrawn.
 
For important restrictions on withdrawals which are applicable to Owners who are
participants under Section 403(b) plans or under the Texas ORP, see
"Tax-Sheltered Annuities" and "Texas Optional Retirement Program."
 
For important tax consequences which may result from surrender and 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 withdrawal is $100, and will be subject to any applicable
withdrawal charges. 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.
Alternatively, 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
 
                                       30
<PAGE>
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 may 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.
    
 
   
LIFE EXPECTANCY DISTRIBUTIONS.  Prior to the Annuity Date, an Owner who also is
the Annuitant may elect to make a series of systematic withdrawals from the
Contract according to the Company's life expectancy distribution ("LED") option
by returning a properly signed LED request form to the Principal Office.
    
 
   
The Owner may elect monthly, bi-monthly, quarterly, semi-annual, or annual LED
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 selected.
    
 
   
If an Owner elects the Company's LED option, in each calendar year a fraction of
the Accumulated Value is withdrawn without a surrender charge based on the
Owner's then life expectancy (or the joint life expectancy of the Owner and a
beneficiary.) 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. Under the Company's LED option, 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. Where the Owner is a trust or
other nonnatural person, the Owner may elect the LED option based on the
Annuitant's life expectancy.
    
 
   
(Note: this option may not produce annual distributions that meet the definition
of "substantially equal periodic payments" as defined under Code Section 72(t).
As such, the withdrawals may be treated by the Internal Revenue Service (IRS) as
premature distributions from the Contract and may be subject to a 10% federal
tax penalty. Owners seeking distributions over their life under this definition
should consult their tax advisor. For more information, see "FEDERAL TAX
CONSIDERATIONS," "B. Taxation of the Contracts in General." In addition, if the
amount necessary to meet the substantially equal periodic payment definition is
greater than the Company's LED amount, a surrender charge may apply to the
amount in excess of the LED amount.)
    
 
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 the Annuitant, Owner or Joint Owner, if applicable, dies while
the Contract is in force, the Company will pay the Beneficiary a death benefit,
except where the Contract is continued in force as provided below in "H. The
Spouse of the Owner as Beneficiary." The amount of the death benefit and the
time requirements for receipt of payment may vary depending upon whether the
Annuitant or an Owner dies first and whether death occurs prior to or after the
Annuity Date.
    
 
   
DEATH OF THE ANNUITANT PRIOR TO THE ANNUITY DATE.  At the death of the Annuitant
(including an Owner who is also the Annuitant), the benefit is equal to the
greatest of (1) the Accumulated Value under the Contract increased by any
positive Market Value Adjustment; (2) gross payments, compounded daily at the
annual rate of 5% starting on the date each payment is applied, decreased
proportionately to reflect withdrawals (except in Hawaii and New York where (b)
equals gross payments decreased proportionately to reflect withdrawals) --
    
 
                                       31
<PAGE>
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; or (3) the death benefit that would have been payable on the most
recent Contract anniversary, increased for subsequent payments and decreased
proportionately for subsequent withdrawals.
 
   
This guaranteed death benefit works in the following way assuming no withdrawals
are made. On the first anniversary, the death benefit will be equal to the
greater of (a) the Accumulated Value (increased by any positive Market Value
Adjustment) or (b) gross payments compounded daily at the annual rate of 5%
(except in Hawaii and New York where (b) equals gross payments). The higher of
(a) or (b) will then be locked in until the second anniversary, at which time
the death benefit will be equal to the greatest of (a) the Contract's then
current Accumulated Value increased by any positive Market Value Adjustment; (b)
gross payments compounded daily at the annual rate of 5% (gross payments in
Hawaii and New York) or (c) the locked-in value of the death benefit at the
first anniversary. The greatest of (a), (b) or (c) will be locked in until the
next Contract anniversary. This calculation will then be repeated on each
anniversary while the Contract remains in force and prior to the Annuity Date.
As noted above, the values of (b) and (c) will be decreased proportionately if
withdrawals are taken. See APPENDIX C, "THE DEATH BENEFIT" for specific examples
of death benefit calculations.
    
 
DEATH OF AN OWNER WHO IS NOT ALSO THE ANNUITANT PRIOR TO THE ANNUITY DATE.  If
an Owner who is not also the Annuitant dies before the Annuity Date, the death
benefit will be the Accumulated Value increased by any positive Market Value
Adjustment. The death benefit will never be reduced by a negative Market Value
Adjustment.
 
PAYMENT OF THE DEATH BENEFIT PRIOR TO THE ANNUITY DATE.  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 Fund. The excess, if any, of the death benefit over the
Accumulated Value will also be added to the Money Market Fund. 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.
 
With respect to the death benefit, the Accumulated Value under the Contract will
be based on the unit values next computed after due proof of the death has been
received.
 
DEATH OF THE ANNUITANT ON OR AFTER THE ANNUITY DATE.  If the Annuitant's death
occurs on or after the Annuity Date but before completion of all guaranteed
annuity benefit payments, any unpaid amounts or installments will be paid to the
Beneficiary. The Company must pay out the remaining payments at least as rapidly
as under the payment option in effect on the date of the Annuitant's death.
 
H.  THE SPOUSE OF THE OWNER AS BENEFICIARY
 
The Owner's spouse, if named as the sole primary 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 become the
 
                                       32
<PAGE>
   
Owner and Annuitant subject to the following: (1) any value in the Guarantee
Period Accounts will be transferred to the Money Market Fund; (2) the excess, if
any, of the death benefit over the Contract's Accumulated Value will also be
added to the Money Market Fund. Additional payments may be made; however, a
surrender charge will apply to these amounts if they have not been invested in
the Contract for more than seven years. 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 one sold in connection with certain qualified plans,
may be assigned by the Owner at any time prior to the Annuity Date and while the
Annuitant is alive. 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.
    
 
For important tax liability which may result from assignments, see "FEDERAL TAX
CONSIDERATIONS."
 
J.  ELECTING THE FORM OF ANNUITY AND THE ANNUITY DATE
 
   
The Owner selects the Annuity Date. To the extent permitted by state law, the
Annuity Date may be the first day of any month (1) before the Annuitant's 85th
birthday, if the Annuitant'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 Annuitant's 90th birthday, if the Annuitant'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. The
new Annuity Date must be the first day of any month occurring before the
Annuitant's 90th birthday and must be within the life expectancy of the
Annuitant. The Company shall determine such life expectancy at the time a change
in Annuity Date is requested. In no event will the maximum annuitization age
exceed 90. 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 Sub-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 option, a payment equal to the value of the
fixed number of Annuity Units in the Sub-Accounts is made monthly, quarterly,
semiannually 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.
    
 
   
The annuity option 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 payout option(s) selected do(es)
not produce an initial payment which meet this minimum, a single payment may be
made. Once the Company begins making annuity benefit payments, the Annuitant
cannot make withdrawals
    
 
                                       33
<PAGE>
or surrender the annuity benefit, except in the case where a commutable period
certain option has been elected. Only beneficiaries entitled to receive
remaining payments for a period certain may elect to instead receive a lump sum
settlement.
 
   
If the Owner does not elect an option, a variable life annuity with periodic
payments guaranteed for ten years 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 the Owner exercises the Minimum Guaranteed Annuity Payout Rider, annuity
benefit payments must be made under a fixed annuity payout option involving a
life contingency and will be determined based on the guaranteed annuity purchase
rates listed under the Annuity Option Tables in the Contract.
    
 
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 Value Portfolio, the Growth Portfolio, the
International Growth Portfolio and the Strategic Income Portfolio.
 
   
The Company also provides these same annuity payout options funded through the
Fixed Account (fixed annuity payout option). Regardless of how payments were
allocated during the accumulation period, any of the variable annuity options or
the fixed-amount options may be selected, or any of the variable annuity options
may be selected in combination with any of the fixed-amount annuity options.
Other annuity options may be offered by the Company. IRS regulations may not
permit certain of the available annuity options when used in connection with
certain qualified Contracts.
    
 
VARIABLE LIFE ANNUITY WITH PAYMENTS GUARANTEED FOR TEN YEARS.  This variable
annuity is payable periodically during the lifetime of the payee with the
guarantee that if the payee should die before all payments have been made, the
remaining annuity benefit payments will continue to the Beneficiary.
 
   
VARIABLE LIFE ANNUITY PAYABLE PERIODICALLY DURING THE LIFETIME OF THE ANNUITANT
ONLY.  This variable annuity is payable during the payee's life. It would be
possible under this option for the payee to receive only one annuity benefit
payment if the payee dies prior to the due date of the second annuity benefit
payment, two annuity benefit payments if the payee dies before the due date of
the third annuity benefit payment, and so on. Payments, however, will continue
during the lifetime of the payee, no matter how long he or she lives.
    
 
UNIT REFUND VARIABLE LIFE ANNUITY.  This is an annuity payable periodically
during the lifetime of the Annuitant with the guarantee that if (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 at
                    annuitization divided by the dollar amount of the first
                    payment, and
    
 
               (2)  is the number of payments paid prior to the death of the
                    payee.
 
JOINT AND SURVIVOR VARIABLE LIFE ANNUITY.  This variable annuity is payable
jointly to two payees during their joint lifetime, and then continues thereafter
during the lifetime of the survivor. The amount of each payment to the survivor
is based on the same number of Annuity Units which applied during the joint
lifetime of the two payees. One of the payees must be either the person
designated as the Annuitant in the Contract or the Beneficiary. There is no
minimum number of payments under this option.
 
JOINT AND TWO-THIRDS SURVIVOR VARIABLE LIFE ANNUITY.  This variable annuity is
payable jointly to two payees during their joint lifetime, and then continues
thereafter during the lifetime of the survivor. The amount of each periodic
payment to the survivor, however, is based upon two-thirds of the number of
Annuity Units
 
                                       34
<PAGE>
which applied during the joint lifetime of the two payees. One of the payees
must be the person designated as the Annuitant in the Contract or the
Beneficiary. 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 30 and may be commutable or
noncommutable. A commutable option provides the payee with the right to request
a lump sum payment of an remaining balance after annuity payments have
commenced. Under a noncommutable period certain option, the Annuitant may not
request a lump sum payment.
    
 
   
It should be noted that the period certain option does not involve a life
contingency. In computing payments under this option, the Company deducts a
charge for annuity rate guarantees, which includes a factor for mortality risks.
Although not contractually required to do so, the Company currently follows a
practice of permitting persons receiving payments under the period certain
option to elect to convert to a variable annuity payout 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. See "FEDERAL TAX CONSIDERATIONS" for a discussion of
the possible adverse tax consequences of selecting a period certain option.
    
 
L.  ANNUITY BENEFIT PAYMENTS
 
   
DETERMINATION OF THE FIRST VARIABLE ANNUITY BENEFIT PAYMENT.  The amount of the
first monthly payment depends upon the selected variable annuity option, the sex
(however, see "N. NORRIS Decision" below) and age of the Annuitant, and the
value of the amount applied under the annuity option ("annuity value"). The
Contract provides annuity rates that determine the dollar amount of the first
periodic payment under each variable annuity option for each $1,000 of applied
value. From time to time, the Company may offer its 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.
    
 
   
The dollar amount of the first periodic annuity benefit payment is calculated
based upon the type of annuity option chosen, as follows:
    
 
   
- -  For life annuity options and noncommutable period certain options of ten
   years or more (six or more years under New York Contracts), the dollar amount
   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 dollar
   amount is determined by multiplying (1) the Surrender Value less premium
   taxes, if any, 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 a death benefit annuity, the annuity value will be the amount of the
   death benefit.
    
 
   
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. The Company transmits variable annuity benefit payments
for receipt by the payee by the first of a month. Variable annuity benefit
payments are currently based on unit values as of the 15th day of the preceding
month.
    
 
   
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
option. The value of an Annuity Unit in each Sub-Account initially 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 net
    
 
                                       35
<PAGE>
   
investment factor of the Sub-Account for the current Valuation Period and
divided by the assumed interest rate for the current Valuation Period The
assumed interest rate, discussed below, is incorporated in the variable annuity
options offered in the Contract.
    
 
   
DETERMINATION OF THE NUMBER OF ANNUITY UNITS.  The dollar amount of the first
variable annuity benefit payment is divided by the value of an Annuity Unit of
the selected Sub-Account(s) 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.
    
 
   
DOLLAR AMOUNT OF SUBSEQUENT VARIABLE ANNUITY BENEFIT PAYMENTS.  The dollar
amount of each periodic variable annuity benefit payment after the first will
vary with the value of the Annuity Units of the selected Sub-Account(s). The
dollar amount of each subsequent variable annuity benefit payment is determined
by multiplying the fixed number of Annuity Units (derived from the dollar amount
of the first payment, as described above) with respect to a Sub-Account by the
value of an Annuity Unit of that Sub-Account on the applicable Valuation Date.
    
 
   
The variable annuity options offered by the Company are based on a 3.5% assumed
interest rate, which affects the amounts of the variable annuity benefit
payments. Variable annuity benefit payments with respect to a Sub-Account will
increase over periods when the actual net investment result of the Sub-Account
exceeds the equivalent of the assumed interest rate. Variable annuity benefit
payments will decrease over periods when the actual net investment results are
less than the equivalent of the assumed interest rate.
    
 
   
For an illustration of a calculation of a variable annuity benefit payment using
a hypothetical example, see "Annuity Benefit Payments" in the SAI.
    
 
   
If the Owner elects the Minimum Guaranteed Annuity Payout Rider, at
annuitization the annuity benefit payments provided under the Rider (by applying
the guaranteed annuity factors to the Minimum Guaranteed Annuity Payout Benefit
Base), are compared to the payments that would otherwise be available with the
Rider. If annuity benefit payments under the Rider are higher, the Owner may
exercise the Rider, provided that the conditions of the Rider are met. If
annuity benefit payments under the Rider are lower, the Owner may choose not to
exercise the Rider and instead annuitize under current annuity factors. See "M.
Optional Minimum Guaranteed Annuity Payout Rider," below.
    
 
   
M.  OPTIONAL MINIMUM GUARANTEED ANNUITY PAYOUT RIDER
    
 
   
An optional Minimum Guaranteed Annuity Payout Rider is available for a separate
monthly charge. The Minimum Guaranteed Annuity Payout Rider guarantees a minimum
amount of fixed annuity lifetime income during the annuity payout phase, subject
to the conditions described below. On each Contract anniversary a Minimum
Guaranteed Annuity Payout Benefit Base is determined. The Minimum Guaranteed
Annuity Payout Benefit Base (less any applicable premium taxes) is the value
that will be annuitized if the Rider is exercised. In order to exercise the
Rider, a fixed annuitization option involving a life contingency must be
selected. Annuitization under this Rider will occur at the guaranteed annuity
purchase rates listed under the Annuity Option Tables in the Contract. The
Minimum Guaranteed Annuity Payout Benefit Base is equal to the greatest of:
    
 
   
    (a) the Accumulated Value increased by any positive Market Value Adjustment,
       if applicable;or
    
 
   
    (b) the Accumulated Value on the effective date of the Rider compounded
       daily at the annual rate of 5% plus gross payments made thereafter
       compounded daily at the annual rate of 5%, starting on the date each
       payment is applied, reduced proportionately to reflect withdrawals; or
    
 
   
    (c) the highest Accumulated Value on any Contract anniversary since the
       Rider effective date, as determined after positive adjustments have been
       made for subsequent payments and any positive
    
 
                                       36
<PAGE>
   
       Market Value Adjustment, if applicable, and negative adjustments have
       been made for subsequent withdrawals.
    
 
   
For each withdrawal described in (b) and (c) above, the proportionate reduction
is calculated by multiplying the (b) or (c) value, whichever is applicable,
determined immediately prior to the withdrawal by the following fraction:
    
 
   
                            amount of the withdrawal
           ----------------------------------------------------------
        Accumulated Value determined immediately prior to the withdrawal
    
 
   
CONDITIONS OF ELECTION OF THE MINIMUM GUARANTEED ANNUITY PAYOUT RIDER.
    
 
   
- -  The Owner may elect the Minimum Guaranteed Annuity Payout Rider at Contract
   issue or at any time thereafter, however, if the Rider is not elected within
   thirty days after Contract issue or within thirty days after a Contract
   anniversary date, the effective date of the Rider will be the following
   Contract anniversary date.
    
 
   
- -  The Owner may not elect a Rider with a ten-year waiting period if at the time
   of election the Annuitant has reached his or her 78th birthday. The Owner may
   not elect a Rider with a fifteen-year waiting period if at the time of
   election the Annuitant has reached his or her 73rd birthday.
    
 
   
EXERCISING THE MINIMUM GUARANTEED ANNUITY PAYOUT RIDER.
    
 
   
- -  The Owner may only exercise the Minimum Guaranteed Annuity Payout Rider
   within thirty days after any Contract anniversary following the expiration of
   a ten or fifteen-year waiting period from the effective date of the Rider.
    
 
   
- -  The Owner may only annuitize under a fixed annuity payout option involving a
   life contingency as provided under "K. Description of Variable Annuity Payout
   Options."
    
 
   
- -  The Owner may only annuitize at the guaranteed annuity purchase rates listed
   under the Annuity Option Tables in the Contract.
    
 
   
TERMINATION OF THE MINIMUM GUARANTEED ANNUITY PAYOUT RIDER.
    
 
   
- -  The Owner may not terminate the Minimum Guaranteed Annuity Payout Rider prior
   to the seventh Contract anniversary after the effective date of the Rider,
   unless such termination occurs on or within thirty days after any Contract
   anniversary and in conjunction with the repurchase of a Minimum Guaranteed
   Annuity Payout Rider with a waiting period of equal or greater length at its
   then current price, if available.
    
 
   
- -  After the seventh Contract anniversary from the effective date of the Rider
   the Owner may terminate the Rider at any time.
    
 
   
- -  The Owner may repurchase a Rider with a waiting period equal to or greater
   than the Rider then in force at the new Rider's then current price, if
   available, however, repurchase may only occur on or within thirty days of a
   Contract anniversary.
    
 
   
- -  Other than in the event of a repurchase, once terminated the Rider may not be
   purchased again.
    
 
   
- -  The Rider will terminate upon surrender of the Contract or the date that a
   death benefit is payable if the Contract is not continued under "H. The
   Spouse of the Owner as Beneficiary" (see "DESCRIPTION OF THE CONTRACT").
    
 
   
From time to time the Company may illustrate minimum guaranteed income amounts
under the Minimum Guaranteed Annuity Payout Rider for individuals based on a
variety of assumptions, including varying rates of
    
 
                                       37
<PAGE>
   
return on the value of the Contract during the accumulation phase, annuity
payout periods, annuity payout options and Minimum Guaranteed Annuity Payout
Rider waiting periods. Any assumed rates of return are for purposes of
illustration only and are not intended as a representation of past or future
investment rates of return.
    
 
   
For example, the illustration below assumes an initial payment of $100,000 for
an Annuitant age 60 (at issue) and exercise of a Minimum Guaranteed Annuity
Payout Rider with a ten-year waiting period. The illustration assumes that no
subsequent payments or withdrawals are made and that the annuity payout option
is a Life Annuity With Payments Guaranteed For 10 Years. The values below have
been computed based on a 5% net rate of return and are the guaranteed minimums
that would be received under the Mimumum Guaranteed Annuity Payout Rider.
    
 
   
The minimum guaranteed benefit base amounts are the values that will be
annuitized. Minimum guaranteed annual income values are based on a fixed annuity
payout.

Annuity With Payments Guaranteed for 10 Years are available. See "K. Description
of Variable Annuity Payout Options."
    
 
   
The Minimum Guaranteed Annuity Payout Rider does not create Accumulated Value or
guarantee performance of any investment option. Because this Rider is based on
conservative actuarial factors, the level of lifetime income that it guarantees
may often be less than the level that would be provided by application of
Accumulated Value at current annuity factors. Therefore, the Rider should be
regarded as a safety net. As described above, withdrawals will reduce the
benefit base.
    
 
   
NOTE: Adding the Minimum Guaranteed Annuity Payout Rider after the issue date
and/or repurchasing the benefit will impact the Program to Protect Principal and
Provide Growth Potential offered under the GPA Accounts since the Minimum
Guaranteed Annuity Payout Rider charges are deducted on a pro-rata basis from
all accounts including the GPA Accounts. See "GUARANTEE PERIOD ACCOUNTS."
    
 
N.  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.
 
O.  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
 
                                       38
<PAGE>
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 Funds. The value of an Accumulation Unit was set at $1.00 on the first
Valuation Date for each Sub-Account.
 
   
Allocations to 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 A, "MORE INFORMATION ABOUT THE FIXED ACCOUNT" AND
"GUARANTEE PERIOD ACCOUNTS."
    
 
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 of 0.20% 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 Accumulation Unit calculation using a hypothetical
example see 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
Funds are described in the prospectuses and SAIs of the Underlying Funds.
    
 
A.  VARIABLE ACCOUNT DEDUCTIONS
 
   
MORTALITY AND EXPENSE RISK CHARGE.  The Company assesses a charge against the
assets of each Sub-Account to compensate for certain mortality and expense risks
its has assumed. 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 payout option selected), no matter
how long the Annuitant (or other payee) 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
    
 
                                       39
<PAGE>
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.
 
   
The mortality and expense risk charge is assessed daily at an annual rate of
1.25% of each Sub-Account's assets. This charge may not be increased. 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 estimates
that a reasonable allocation might be 0.80% for mortality risk and 0.45% for
expense risk.
    
 
   
ADMINISTRATIVE EXPENSE CHARGE.  The Company assesses each Sub-Account with a
daily charge at an annual rate of 0.20% 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 (described below under "B. Contract Fee") 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
Funds, the value of the net assets of the Sub-Accounts will reflect the
investment advisory fee and other expenses incurred by the Funds. The
prospectuses and SAIs of the Underlying Funds contain additional information
concerning expenses of the Funds.
    
 
B.  CONTRACT FEE
 
A $30 Contract fee currently is deducted on the Contract anniversary date and
upon full surrender of the Contract when the Accumulated Value is less than
$100,000. The Contract fee is waived for contracts issued to and maintained by
the trustee of a 401(k) plan. 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.
 
Where permitted by law, the Contract fee also may be waived for Contracts where,
on the issue date, either the Owner or the Annuitant is within the following
class 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
Funds; 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 MINIMUM GUARANTEED ANNUITY PAYOUT RIDER CHARGE
    
 
   
Subject to state availability, the Company offers an optional Minimum Guaranteed
Annuity Payout 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 the applicable annual rate (see table
below) is made against the Accumulated Value of the Contract at that time. The
charge is made through a pro-rata reduction of the Accumulated Value of the
Sub-Accounts, the Fixed Account and the Guarantee Period Accounts (based on the
relative value that the Accumulation Units of the Sub-Accounts, the dollar
amounts in the Fixed Account and the dollar amounts in the Guarantee Period
Accounts bear to the total Accumulated Value).
    
 
   
The applicable charge is assessed on the Accumulated Value on the last day of
each month and on the date the Rider is terminated, multiplied by 1/12th of the
following annual percentage rates:

</TABLE>
    
 
   
For a description of the Rider, see "M. Optional Minimum Guaranteed Annuity
Payout Rider" 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 in total 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
 
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.  SURRENDER CHARGE
    
 
   
No charge for sales expense is deducted from payments at the time the payments
are made. A surrender charge is deducted, however, from the Accumulated Value of
the Contract in the case of surrender of and/or withdrawals from the Contract or
at the time annuity benefit payments begin, within certain time limits described
below.
    
 
   
For purposes of determining the surrender charge, the Accumulated Value is
divided into three categories: (1) New Payments -- payments received by the
Company during the seven years preceding the date of the surrender; (2) Old
Payments -- accumulated payments invested in the Contract for more than seven
years; and (3) the amount available under the Withdrawal Without Surrender
Charge provision. See "Withdrawal Without Surrender Charge" below. For purposes
of determining the amount of any surrender charge,
    
 
                                       41
<PAGE>
   
surrenders will be deemed to be taken first from amounts available as a
Withdrawal Without Surrender Charge, if any; then from any Old Payments, and
then from New Payments. Amounts available as a Withdrawal Without Surrender
Charge, followed by Old Payments, may be withdrawn from the Contract at any time
without the imposition of a surrender charge. If a withdrawal is attributable
all or in part to New Payments, a surrender charge may apply.
    
 
   
CHARGE FOR SURRENDER AND WITHDRAWALS.  If a Contract is surrendered, or if New
Payments are withdrawn while the Contract is in force and before the Annuity
Date, a surrender charge may be imposed. The amount of the charge will depend
upon the number of years that any New Payments, to which the withdrawal is
attributed have remained credited under the Contract. Amounts withdrawn are
deducted first from Old Payments. Then, for the purpose of calculating surrender
charges for New Payments, all amounts withdrawn are assumed to be deducted first
from the oldest New Payment and then from the next oldest New Payment and so on,
until all New Payments have been exhausted pursuant to the first-in-first-out
("FIFO") method of accounting. (See "FEDERAL TAX CONSIDERATIONS" for a
discussion of how withdrawals are treated for income tax purposes.)
    
 
   
The Surrender Charge is as follows:
    
 
<TABLE>
<CAPTION>
       YEARS FROM DATE             CHARGE AS PERCENTAGE OF
          OF PAYMENT                NEW PAYMENTS WITHDRAWN

<S>                             <C>
             0-1                              7%
              2                               6%
              3                               5%
              4                               4%
              5                               3%
              6                               2%
              7                               1%
         More than 7                          0%
</TABLE>
 
   
The amount withdrawn equals the amount requested by the Owner plus the surrender
charge, if any. The charge is applied as a percentage of the New Payments
withdrawn, but in no event will the total surrender charge exceed a maximum
limit of 7% of total gross New Payments. Such total charge equals the aggregate
of all applicable surrender charges for surrender, withdrawals, and
annuitization.
    
 
   
REDUCTION OR ELIMINATION OF SURRENDER CHARGE AND ADDITIONAL AMOUNTS
CREDITED.  Where permitted by state law, the Company will waive the surrender
charge in the event that an Owner (or the Annuitant, if the Owner is not an
individual) becomes physically disabled after the issue date of the Contract and
before attaining age 65. Under New York Contracts, the disability also must
exist for a continuous period of at least four months. The Company may require
proof of such disability and continuing disability, including written
confirmation of receipt and approval of any claim for Social Security Disability
Benefits and reserves the right to obtain an examination by a licensed physician
of its choice and at its expense. In addition, except in New York and New Jersey
where not permitted by state law, the Company will waive the in the event that
an Owner (or the Annuitant, if the Owner is not an individual) is: (1) admitted
to a medical care facility and remains confined there until the later of one
year after the issue date or 90 consecutive days or (2) first diagnosed by a
licensed physician as having a fatal illness after the issue date of the
Contract.
    
 
For purposes of the above provision, "medical care facility" means any
state-licensed facility or, in a state that does not require licensing, a
facility that is operating pursuant to state law, providing medically necessary
inpatient care which is prescribed in writing by a licensed "physician" and
based on physical limitations which prohibit daily living in a non-institutional
setting; "fatal illness" means a condition diagnosed by a licensed "physician"
which is expected to result in death within two years of the diagnosis; and
"physician" means a person other than the Owner, Annuitant or a member of one of
their families who is state licensed to give medical care or treatment and is
acting within the scope of that license.
 
                                       42
<PAGE>
   
Where surrender charges have been waived under any of the situations discussed
above, no additional payments under the Contract will be accepted, unless
required by state law.
    
 
   
In addition, where permitted by state law, the Company may reduce or waive
surrender charges and/or credit additional amounts on Contracts issued where
either the Owner or the Annuitant on the issue date is within the following
class 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
subsidiaries and affiliates; officers, directors, trustees and employees of any
of the Funds, investment managers or sub-advisers; and the spouses, children and
other legal dependants (under age 21) of such eligible persons.
    
 
   
In addition, from time to time the Company may reduce the amount of the
surrender charge, the period during which it applies, or both, and/or credit
additional amounts on the Contract when the Contract is sold to individuals or
groups of individuals in a manner that reduces sales expenses. The Company will
consider (1) the size and type of group; (2) the total amount of payments to be
received and the manner in which payments are remitted; (3) the purpose for
which the Contract is 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). Finally, if permitted under state law, surrender charges
may be waived under Section 403(b) Contracts where the amount withdrawn is being
contributed to a life insurance policy issued by the Company as part of the
individual's Section 403(b) plan. Any reduction or elimination in the amount or
duration of the surrender charge will not discriminate unfairly among Owners.
The Company will not make any changes to this charge where prohibited by law.
    
 
   
Pursuant to Section 11 of the 1940 Act and Rule 11a-2 thereunder, the surrender
charge is modified to effect certain exchanges of existing contracts issued by
the Company for this Contract. See "Exchange Offer" in the SAI.
    
 
   
WITHDRAWAL WITHOUT SURRENDER CHARGE.  In each calendar year, the Company will
waive the surrender charge, if any, on an amount ("Withdrawal Without Surrender
Charge") equal to the greatest of (1), (2) or (3):
    
 
Where:  (1)  is:  The Accumulated Value as of the Valuation Date coincident with
                  or next following the date of receipt of the request for
                  withdrawal, reduced by total gross payments not previously
                  withdrawn ("Cumulative Earnings")
 
   
Where:  (2)  is:  15% of the Accumulated Value as of the Valuation Date
                  coincident with or next following the date of receipt of the
                  request for withdrawal, reduced by the total amount of any
                  prior withdrawals made in the same calendar year to which no
                  surrender charge was applied.
    
 
   
Where:  (3)  is:  The amount calculated under the Company's life expectancy
                  distribution (see "Life Expectancy Distributions" above)
                  whether or not the withdrawal was part of such distribution
                  (applies only if the Annuitant is also an Owner).
    
 
For example, an 81-year-old Owner/Annuitant with an Accumulated Value of
$15,000, of which $1,000 is Cumulative Earnings, would have a Withdrawal Without
Surrender Charge of $2,250, which is equal to the greatest of:
 
    (1) Cumulative Earnings ($1,000);
 
    (2) 15% of Accumulated Value ($2,250); or
 
                                       43
<PAGE>
    (3) LED of 10.2% of Accumulated Value ($1,530).
 
   
The Withdrawal Without Surrender Charge will first be deducted from Cumulative
Earnings. If the Withdrawal Without Surrender Charge exceeds Cumulative
Earnings, the excess amount will be deemed withdrawn from payments not
previously withdrawn on a last-in-first-out ("LIFO") basis. If more than one
withdrawal is made during the year, on each subsequent withdrawal the Company
will waive the surrender charge, if any, until the entire Withdrawal Without
Surrender Charge amount has been 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.
    
 
   
SURRENDERS.  In the case of a complete surrender, the amount received by the
Owner is equal to the entire Accumulated Value under the Contract, net of the
applicable surrender charge on New Payments, the Contract fee and any applicable
tax withholding, and adjusted for any applicable Market Value Adjustment.
Subject to the same rules applicable to withdrawals, the Company will not assess
a surrender charge on an amount equal to the greater of the Withdrawal Without
Surrender Charge amount, described above, or the life expectancy distribution,
if applicable.
    
 
   
Where an Owner who is a trustee under a pension plan surrenders, in whole or in
part, the Contract on a terminating employee, the trustee will be permitted to
reallocate all or a part of the total Accumulated Value under the Contract to
other Contracts issued by the Company and owned by the trustee, with no
deduction for any otherwise applicable surrender charge. Any such reallocation
will be at the unit values for the Sub-Accounts as of the Valuation Date on
which a written, signed request is received at the Principal Office.
    
 
For further information on surrender and withdrawal, including minimum limits on
amount withdrawn and amounts remaining under the Contract in the case of
withdrawal, and important tax considerations, see "E. Surrender" and "F.
Withdrawals" under "DESCRIPTION OF CONTRACT," and see "FEDERAL TAX
CONSIDERATIONS."
 
   
CHARGE AT THE TIME ANNUITY BENEFIT PAYMENTS BEGIN.  If the Owner chooses a
commutable period certain option or a noncommutable period certain option for
less than ten years (less than six years under New York contracts) , a surrender
charge will be deducted from the Accumulated Value of the Contract if the
Annuity Date occurs at any time when a surrender charge would still apply had
the Contract been surrendered on the Annuity Date.
    
 
   
No surrender charge is imposed at the time of annuitization in any Contract year
under an option involving a life contingency or for any noncommutable period
certain option for ten years or more (six or more years under New York
contracts). A Market Value Adjustment, however, may apply. See "GUARANTEE PERIOD
ACCOUNTS."
    
 
   
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 the Contract offered in this
Prospectus. The proceeds of the fixed contract, minus any surrender charge
applicable under the fixed contract if a period certain option is chosen, 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.
    
 
F.  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 to reimburse it for
the expense of processing transfers. For more information, see "D. Transfer
Privilege."

                           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 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 this Contract or any 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 this Prospectus.
 
   
INVESTMENT OPTIONS.  In most jurisdictions, Guarantee Periods ranging from two
through ten years may be available under the Contract. Each Guarantee Period
Account established for the Owner is accounted for separately in a non-unitized
segregated account, except in California where it is accounted for in the
Company's General 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 the 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. (In Oregon and
Massachusetts, payments and transfers to the Fixed Account are subject to
certain restrictions. See APPENDIX A.) 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 Account 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 Fund. 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 will be
automatically 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 the
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 Money Market Fund. Where amounts have been
automatically renewed into 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
 
                                       45
<PAGE>
Value. See "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. 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 before deduction of any
Surrender Charge by the market value factor. The market value factor for each
Guarantee Period Account is equal to:
 
                            [(1+i)/(1+j)](n/365) - 1
 
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.
 
   
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 also is 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, "SURRENDER CHARGES AND
THE MARKET VALUE ADJUSTMENT."
    
 
   
PROGRAM TO PROTECT PRINCIPAL AND PROVIDE GROWTH POTENTIAL.  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
(including withdrawals made as part of a pro-rata deduction for charges under a
Minimum Guaranteed Annuity Payout Rider purchased or repurchased after issue),
in order to ensure that on the last day of the Guarantee Period, the value in
the Guarantee Period Account will equal the amount of the entire initial
payment. The required amount then will be allocated to the preselected 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, including Withdrawals Without
Surrender Charge, 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
 
                                       46
<PAGE>
   
adjustment will be made to the amount payable. If a surrender charge applies to
the withdrawal, it will be calculated as set forth under "D. Surrender Charge"
after application of the Market Value Adjustment.
    
 
                           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, Annuitant, 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 this 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 Internal Revenue Code (the "Code"). The Company files a consolidated tax
return with its affiliates.
 
   
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 prescribed by the Treasury Department 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. Under this section of the Code, if the investments are not
adequately diversified, the Contract will not be treated as an annuity contract,
and therefore the income on the Contract, for any taxable year of the Owner,
would be treated as ordinary income received or accrued by the Owner. It is
anticipated that the Portfolios of the Fund in this Contract 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, traditionally 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 now 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
    
 
                                       47
<PAGE>
   
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 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 "D. Provisions Applicable to Qualified Employer Plans"
below.
 
B.  TAXATION OF THE CONTRACTS IN GENERAL
 
   
The Company believes that the Contract described in this Prospectus will, with
certain exceptions (see "Nonnatural 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 Contract may not be considered an annuity for tax purposes, and therefore,
the Owner will be taxed on the annual increase in 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 cost basis of 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 cost basis in the
Contract is recovered, the entire payment is taxable. If the annuitant dies
before the cost basis is recovered, a deduction for the difference is allowed on
the annuitant'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 the 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
 
                                       48
<PAGE>
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 payee.
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 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 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 any LED-type 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. Where the Owner and Annuitant are different
persons, the change of ownership of the Contract to the Annuitant on the Annuity
Date, as required under the Contract, is a gift and will be taxable to the Owner
as such; however, the Owner will not incur taxable income. Instead, the
Annuitant will incur taxable income upon receipt of annuity benefit payments as
discussed above.
 
   
NONNATURAL OWNERS.  As a general rule, deferred annuity contracts owned by
"nonnatural 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. With respect to payments made
after February 28, 1986, however, a contract owned by a state or local
government or a tax-exempt organization will not be treated as an annuity under
Section 72. 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.
 
                                       49
<PAGE>
The tax treatment of certain withdrawals or surrenders of the non-qualified
Contracts offered by this Prospectus will vary according to whether or not the
amount withdrawn or surrendered is allocable to an investment in the Contract
made before or after certain dates.
 
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.
 
A qualified Contract may include special provisions (endorsements) changing or
restricting rights and benefits otherwise available to an Owner of a
non-qualified Contract. Individuals purchasing a qualified Contract should
review carefully 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 Contract 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 Annuities."
    
 
Eligible employers that meet specified criteria may establish simplified
employee pension plans (SEP-IRAs) or SIMPLE IRA plans for their employees using
the employees 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 annuity 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
 
                                       50
<PAGE>
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.
 
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.
 
   
                             STATEMENTS AND REPORTS
    
 
   
The Owner is sent a report semi-annually which provides certain financial
information about the Funds. At least annually, but possibly as frequent as
quarterly, the Company will furnish a statement to the Owner containing
information about his or her Contract, including Accumulation Unit Values and
other information as required by applicable law, rules and regulations . The
Company will also send a confirmation statement to Owners each time a
transaction is made affecting the Contract Value. (Certain transactions made
under recurring payment plans such as Dollar Cost Averaging may in the future be
confirmed quarterly rather than by immediate confirmations.) The Owner should
review the information in all statements carefully. All errors or corrections
must be reported to the Company immediately to assure proper crediting to the
Contract. The Company will assume that all transactions are accurately reported
on confirmation statements and quarterly/ annual statements unless the Owner
notifies the Principal Office in writing within 30 days after receipt of the
statement.
    
 
                        LOANS (QUALIFIED CONTRACTS ONLY)
 
Loaned amounts will first be withdrawn 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
(last-in, first-out) 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 instead be allocated to
the Money Market Fund.
 
               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 Fund
are no longer available for investment or if in the Company's judgment further
investment in any Fund should become inappropriate in view of the purposes of
the Variable Account or the affected Sub-Account, the Company may redeem the
shares of that Fund and substitute shares of another registered open-end
management company. The Company will not substitute any shares attributable to a
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 the 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
fund 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,
 
                                       51
<PAGE>
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 Funds also are issued to variable accounts of the Company and its
affiliates which issue variable life contracts ("mixed funding"). Shares of the
Funds are also issued to other unaffiliated insurance companies ("shared
funding"). Shares of the Funds may be offered to certain qualified retirement
plans. It is conceivable that in the future such mixed funding, shared funding
or sales to qualified plans may be disadvantageous for variable life owners,
variable annuity owners or plan participants. Although the Company and the
Trustees of the Underlying Funds do not currently foresee any such disadvantages
to variable life insurance owners, variable annuity owners or plan participants,
the Company and the respective Trustees intend to monitor events in order to
identify any material conflicts and to determine what action, if any, should be
taken in response thereto. If the Trustees were to conclude that separate funds
should be established for variable life and variable annuity separate accounts,
the Company may be required to bear the attendant expenses.
 
If any of these substitutions or changes are made, the Company may, by
appropriate endorsement, change 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 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 Fund shares held by a Sub-Account, in the
event that Fund shares are unavailable for investment, or if the Company
determines that further investment in such 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 the Owners the benefit of, any federal or
state statute, rule or regulations, including but not limited to requirements
for annuity contracts and retirement plans under the Code and pertinent
regulations or any state statute or regulation. 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 Fund shares held by each Sub-Account in accordance with
instructions received from Owners and, after the Annuity Date, from the
Annuitants. Each person having a voting interest in a Sub-Account will be
provided with proxy materials of the Fund 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.
 
                                       52
<PAGE>
The number of votes which an Owner or Annuitant may cast will be determined by
the Company as of the record date established by the Fund. During the
accumulation phase, the number of Fund 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 Fund share.
During the annuity payout phase, the number of Fund shares attributable to each
Annuitant will be determined by dividing the reserve held in each Sub-Account
for the Annuitant's variable annuity by the net asset value of one Fund share.
Ordinarily, the Annuitant's voting interest in the Fund will decrease as the
reserve for the variable annuity is depleted.
 
                                  DISTRIBUTION
 
The Contract offered by this Prospectus may be purchased from certain
independent broker-dealers which are registered under the Securities Exchange
Act of 1934 and members of the National Association of Securities Dealers, Inc.
("NASD"). The Contract also is offered through Allmerica Investments, Inc.,
which is the principal underwriter and distributor of the Contract. Allmerica
Investments, Inc., 440 Lincoln Street, Worcester, MA 01653, is a registered
broker-dealer, member of the NASD, and an indirect wholly owned subsidiary of
First Allmerica.
 
   
The Company pays commissions, not to exceed 6.5% of payments, to broker-dealers
which sell the Contract. Alternative commission schedules are available with
lower initial commission amounts based on payments, plus ongoing annual
compensation of up to 1% of Contract value. To the extent permitted by NASD
rules, promotional incentives or payments may also be provided to such broker-
dealers based on sales volumes, the assumption of wholesaling functions, or
other sales-related criteria. Additional payments may be made for other services
not directly related to the sale of the Contract, including the recruitment and
training of personnel, production of promotional literature, and similar
services.
    
 
   
The Company intends to recoup commissions and other sales expenses through a
combination of anticipated surrender charges and profits from the Company's
General Account, which may include amounts derived from mortality and expense
risk charges. Commissions paid on the Contract, including additional incentives
or payments, do not result in any additional charge to Owners or to the Variable
Account. Any surrender charges assessed on the Contract will be retained by the
Company.
    
 
Owners may direct any inquiries to their financial representative or to
Allmerica Investments, Inc., 440 Lincoln Street, Worcester, MA 01653, telephone

reimbursement for certain administrative and distribution support services
provided to the Lazard Retirement International Equity Portfolio.
 
                                 LEGAL MATTERS
 
   
There are no legal proceedings pending to which the Variable Account is a party,
or to which the assets of the Variable Account are subject. The Company and the
Principal Underwriter are not involved in any litigation that is of material
importance in relation to their total assets or that relates to the Variable
Account.
    
 
   
                              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 suppliers 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 Company's involvement on 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 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 cost of the Year 2000 project will be expensed as incurred and is being
funded primarily through a reallocation of resources from discretionary projects
and a reduction in systems maintenance and support costs. 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.
The Company and its affiliates have incurred and expensed approximately $54
million related to the assessment, plan development and substantial completion
of the Year 2000 project, through December 31, 1998. The total remaining cost of
the project is estimated between $20-30 million.

                              FURTHER INFORMATION
 
A Registration Statement under the 1933 Act relating to this offering has been
filed with the SEC. Certain portions of the Registration Statement and
amendments have been omitted in this Prospectus pursuant to the rules and
regulations of the SEC. The omitted information may be obtained from the SEC's

                                   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 the Prospectus.
The disclosures in this APPENDIX A have not been reviewed by the SEC.
 
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 the 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.
 
   
If the Contract is surrendered, or if an amount in excess of the Withdrawal
Without Surrender Charge is withdrawn, while the Contract is in force and before
the Annuity Date, a surrender charge is imposed if such event occurs before the
payments attributable to the surrender or withdrawal have been credited to the
Contract at least seven full contract years.
    
 
In Massachusetts, payments and transfers to the Fixed Account are subject to the
following restrictions:
 
        If a Contract is issued prior to the Annuitant's 60th birthday,
        allocations to the Fixed Account will be permitted until the Annuitant's
        61st birthday. On and after the Annuitant's 61st birthday, no additional
        Fixed Account allocations will be accepted. If a Contract is issued on
        or after the Annuitant's 60th birthday, up through and including the
        Annuitant's 81st birthday, Fixed Account allocations will be permitted
        during the first Contract year. On and after the first Contract
        anniversary, no additional allocations to the Fixed Account will be
        permitted. If a Contract is issued after the Annuitant's 81st birthday,
        no payments to the Fixed Account will be permitted at any time.
 
If an allocation designated as a Fixed Account allocation is received at the
Principal Office during a period when the Fixed Account is not available due to
the limitations outlined above, the monies will be allocated to the Money Market
Fund.
 
In Oregon, no payment to the Fixed Account will be permitted if a Contract is
issued after the Annuitant's 81st birthday.
 
   
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. The Company reserves the right
to extend the period of time that the enhanced rate will apply. For more
information, please contact your financial representative or call
1-800-917-1909.

PART 2: MARKET VALUE ADJUSTMENT
 
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

                  TAXATION OF THE CONTRACT, THE VARIABLE
                         ACCOUNT AND THE COMPANY

The Company currently imposes no charge for taxes payable in connection with 
the Contract, other than for state and local premium taxes and similar 
assessments when applicable. The Company reserves the right to impose a 
charge for any other taxes that may become payable in the future in 
connection with the Contract or the Variable Account.

The Variable Account is considered to be 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 Internal Revenue Code (the "Code"), and files a 
consolidated tax return with its parent and affiliated companies.

The Company reserves the right to make a charge for any effect which the 
income, assets, or existence of the Contract or the Variable Account may have 
upon its tax. Such charge for taxes, if any, will be assessed on a fair and 
equitable basis in order to preserve equity among classes of Contract Owners 
("Owners"). The Variable Account presently is not subject to tax.

                               SERVICES

CUSTODIAN OF SECURITIES. The Company serves as custodian of the assets of the

                                 UNDERWRITERS

Allmerica Investments, Inc. ("Allmerica Investments"), a registered 
broker-dealer under the Securities Exchange Act of 1934 and a member of the 
National Association of Securities Dealers, Inc. ("NASD"), serves as 
principal underwriter and general distributor for the Contract pursuant to a 
contract with Allmerica Investments, the Company and the Variable Account. 
Allmerica Investments distributes the Contract on a best-efforts basis. 
Allmerica Investments, Inc., 440 Lincoln Street, Worcester, Massachusetts 
01653, was organized in 1969 as a wholly owned subsidiary of First Allmerica, 
and presently is indirectly wholly owned by First Allmerica.

The Contract offered by this Prospectus is offered continuously, and may be 
purchased from certain independent broker-dealers which are NASD members and 
whose representatives are authorized by applicable law to sell variable 
annuity contracts.

All persons selling the Contract are required to be licensed by their 
respective state insurance authorities for the sale of variable annuity 
contracts. The Company pays commissions, not to exceed 6.5% of purchase 
payments, to entities which sell the Contract. To the extent permitted by 
NASD rules, promotional incentives or payments also may be provided to such 
entities based on sales volumes, the assumption of wholesaling functions or 
other sales-related criteria. Additional payments may be made for other 
services not directly related to the sale of the Contract, including the 
recruitment and training of personnel, production of promotional literature 
and similar services.

Commissions paid on the Contract, including additional incentives or 
payments, and allowances paid, if any, are paid by the Company and do not 
result in any charge to Owners or to the Variable Account in addition to the 
charges described under "CHARGES AND DEDUCTIONS" in the Prospectus. The 
Company intends to recoup the commission and other sales expense through a 
combination of anticipated surrender, withdrawal and/or annuitization 
charges, profits from the Company's general account, including the investment 
earnings on amounts allocated to accumulate on a fixed basis in excess of the 
interest credited on fixed accumulations by the Company, and the profit, if 
any, from the mortality and expense risk charge.

   
No commissions paid were paid to Allmerica Investments, Inc. during 1998 and 
1997. Sales of these contracts began in 1997.
    

                          ANNUITY BENEFIT PAYMENTS

The method by which the Accumulated Value under the Contract is determined is 
described in detail under "Computation of Values" in the Prospectus.

ILLUSTRATION OF ACCUMULATION UNIT CALCULATION USING HYPOTHETICAL EXAMPLE. The 
Accumulation Unit calculation for a daily Valuation Period may be illustrated 
by the following hypothetical example: Assume that the assets of a 
Sub-Account at the beginning of a one-day Valuation Period were $5,000,000; 
that the value of an Accumulation Unit on the previous date was $1.135000; 
and that during the Valuation Period, the investment income and net realized 
and unrealized capital gains exceed net realized and unrealized capital 
losses by $1,675. The Accumulation Unit Value at the end of the current 
Valuation Period would be calculated as follows:

Conversely, if unrealized capital losses and charges for expenses and taxes 
exceeded investment income and net realized capital gains by $1,675, the 
Accumulation Unit Value at the end of the Valuation Period would have been 
$1.134574.

The method for determining the amount of annuity benefit payments is 
described in detail under "Determination of the First and Subsequent Annuity 
Benefit Payments" in the Prospectus.

   
ILLUSTRATION OF VARIABLE ANNUITY PAYMENT CALCULATION USING HYPOTHETICAL 
EXAMPLE. The determination of the Annuity Unit value and the variable annuity 
benefit payment may be illustrated by the following hypothetical example: 
Assume an Annuitant has 40,000 Accumulation Units in a Variable Account, and 
that the value of an Accumulation Unit on the Valuation Date used to 
determine the amount of the first variable annuity payment is $1.120000. 
Therefore, the Accumulation Value of the Contract is $44,800 (40,000 x 
$1.120000). Assume also that the Owner elects an option for which the first 
monthly payment is $6.57 per $1,000 of Accumulated Value applied. Assuming no 
premium tax or surrender charge, the first monthly payment would be 44.800 
multiplied by $6.57, or $294.34.
    

Next, assume that the Annuity Unit value for the assumed rate of 3.5% per 
annum for the Valuation Date as of which the first payment was calculated was 
$1.100000. Annuity Unit values will not be the same as Accumulation Unit 
Values because the former reflect the 3.5% assumed interest rate used in the 
annuity rate calculations. When the Annuity Unit value of $1.100000 is 
divided into the first monthly payment, the number of Annuity Units 
represented by that payment is determined to be 267.5818. The value of this 
same number of Annuity Units will be paid in each subsequent month under most 
options. Assume further that the net investment factor for the Valuation 
Period applicable to the next annuity benefit payment is 1.000190. 
Multiplying this factor by .999906 (the one-day adjustment factor for the 
assumed interest rate of 3.5% per annum) produces a factor of 1.000096. This 
then is multiplied by the Annuity Unit value on the immediately preceding 
Valuation Date (assumed here to be $1.105000). The result is an Annuity Unit 
value of $1.105106 for the current monthly payment. The current monthly 
payment then is determined by multiplying the number of Annuity Units by the 
current Annuity Unit value, or 267.5818 times $1.105106, which produces a 
current monthly payment of $295.71.

METHOD FOR DETERMINING COMMUTED VALUE ON VARIABLE ANNUITY PERIOD CERTAIN 
OPTIONS AND ILLUSTRATION USING HYPOTHETICAL EXAMPLE. The Contract offers both 
commutable and non-commutable period certain options. A commutable option 
gives the Annuitant the right to exchange any remaining payments for a lump 
sum payment based on the commuted value. The Commuted Value is the present 
value of remaining payments calculated at 3.5% interest. The determination of 
the Commuted Value may be illustrated by the following hypothetical example.

Assume a commutable period certain option is elected. The number of Annuity 
Units upon which each payment is based would be calculated using the 
Surrender Value less any premium tax rather than the Accumulated Value. 
Assume this results in 250.0000 Annuity Units. Assume the Commuted Value is 
requested with 60 monthly payments remaining and a current Annuity Unit Value 
of $1.200000. Based on these assumptions, the dollar amount of remaining 
payments would be $300 a month for 60 months. The present value at 3.5% of 
all remaining payments would be $16,560.72.

                                EXCHANGE OFFER


A.  VARIABLE ANNUITY CONTRACT EXCHANGE OFFER

The Company will permit Owners of certain variable annuity contracts, 
described below, to exchange their contracts at net asset value for the 
variable annuity Contract described in the Prospectus, which is issued on 
Form No. A3026-96 or a state variation thereof ("new Contract"). The Company 
reserves the right to suspend this exchange offer at any time.

This offer applies to the exchange of Elective Payment Variable Annuity 
contracts issued on Forms A3012-79 and A3013-79 ("Elective Payment Exchanged 
Contract," all such contracts having numbers with a "JQ" or "JN" prefix), and 
Single Payment Variable Annuity contracts issued on Forms A3014-79 and 
A3015-79 ("Single Payment Exchanged Contract," all such contracts having 
numbers with a "KQ" or "KN" prefix). These contracts are referred to 
collectively as the "Exchanged Contract" To effect an exchange, the Company 
should receive (1) a completed application for the new Contract, (2) the 
contract being exchanged, and (3) a signed Letter of Awareness.

   
SURRENDER CHARGE COMPUTATION. No surrender charge otherwise applicable to the 
Exchanged Contract will be assessed as a result of the exchange. Instead, the 
surrender charge under the new Contract will be computed as if the payments 
that had been made to the Exchanged Contract were made to the new Contract, 
as of the date of issue of the Exchanged Contract. Any additional payments to 
the new Contract after the exchange will be subject to the surrender charge 
computation outlined in the new Contract and the Prospectus; i.e., the charge 
will be computed based on the number of years that the additional payment (or 
portion of that payment) that is being withdrawn has been credited to the new 
Contract.
    

SUMMARY OF DIFFERENCES BETWEEN THE EXCHANGED CONTRACT AND THE NEW CONTRACT. 
The new Contract and the Exchanged Contract differ substantially as 
summarized below. There may be additional differences important to a person 
considering an exchange, and the Prospectuses for the new Contract and the 
Exchanged Contract should be reviewed carefully before the exchange request 
is submitted to the Company.

   
SURRENDER CHARGE. The surrender charge under the new Contract, as described 
in the Prospectus, imposes higher charge percentages against the excess 
amount redeemed than the Single Payment Exchanged Contract. In addition, if 
an Elective Payment Exchanged Contract was issued more than nine years before 
the date of an exchange under this offer, additional payments to the 
Exchanged Contract would not be subject to a surrender charge. New payments 
to the new Contract may be subject to a charge if withdrawn prior to the 
surrender charge period described in the Prospectus.
    

CONTRACT FEE. Under the new Contract, the Company deducts a $30 fee on each 
Contract anniversary and at surrender if the Accumulated Value is less than 
$100,000. This fee is waived if the new Contract is part of a 401(k) plan. No 
Contract fees are charged on the Single Payment Exchanged Contract. A $9 
semi-annual fee is charged on the Elective Payment Exchanged Contract if the 
Accumulated Value is $10,000 or less.

VARIABLE ACCOUNT ADMINISTRATIVE EXPENSE CHARGE. Under the new Contract, the 
Company assesses each Sub-Account a daily administrative expense charge at an 
annual rate of 0.20% of the average daily net assets of the Sub-Account. No 
administrative expense charge based on a percentage of Sub-Account assets is 
imposed under the Exchanged Contract.

TRANSFER CHARGE. No charge for transfers is imposed under the Exchanged 
Contract. Currently, no transfer charge is imposed under the new Contract; 
however, the Company reserves the right to assess a charge not to exceed $25 
for each transfer after the twelfth in any Contract year.

                                       6

<PAGE>

DEATH BENEFIT. The Exchanged Contract offers a death benefit that is 
guaranteed to be the greater of a Contract's Accumulated Value or gross 
payments made (less withdrawals). At the time an exchange is processed, the 
Accumulated Value of the Exchanged Contract becomes the "payment" for the new 
Contract. Therefore, prior purchase payments made under the Exchanged 
Contract (if higher than the Exchanged Contract's Accumulated Value) no 
longer are a basis for determining the death benefit under the new Contract. 
Consequently, whether the initial minimum death benefit under the new 
Contract is greater than, equal to, or less than, the death benefit of the 
Exchanged Contract depends on whether the Accumulated Value transferred to 
the new Contract is greater than, equal to, or less than, the gross payments 
under the Exchanged Contract. In addition, under the Exchanged Contract, the 
amount of any prior withdrawals is subtracted from the value of the death 
benefit. Under the new Contract, where there is a reduction in the death 
benefit amount due to a prior withdrawal, the value of the death benefit is 
reduced in the same proportion that the new Contract's Accumulated Value was 
reduced on the date of the withdrawal.

ANNUITY TABLES.  The Exchanged Contract contains higher guaranteed annuity 
rates.

B.  FIXED ANNUITY EXCHANGE OFFER
   
This exchange offer also applies to all fixed annuity contracts issued by the 
Company. A fixed annuity contract to which this exchange offer applies may be 
exchanged at net asset value for the Contract described in this Prospectus, 
subject to the same provisions for effecting the exchange and for applying 
the new Contract's surrender charge as described above for variable annuity 
contracts. This Prospectus should be read carefully before making such 
exchange. Unlike a fixed annuity, the new Contract's value is not guaranteed, 
and will vary depending on the investment performance of the Underlying Funds 
to which it is allocated. The new Contract has a different charge structure 
than a fixed annuity contract, which includes not only a surrender charge 
that may vary from that of the class of contracts to which the exchanged 
fixed contract belongs, but also Contract fees, mortality and expense risk 
charges (for the Company's assumption of certain mortality and expense 
risks), administrative expense charges, transfer charges (for transfers 
permitted among Sub-Accounts and the Fixed Account), and expenses incurred by 
the Underlying Funds. Additionally, the interest rates offered under the 
Fixed Account of the new Contract and the Annuity Tables for determining 
minimum annuity benefit payments may be different from those offered under 
the exchanged fixed contract.
    

C.  EXERCISE OF "FREE-LOOK PROVISION" AFTER ANY EXCHANGE
   
Persons who, under the terms of this exchange offer, exchange their contract 
for the new Contract and subsequently cancel the new Contract within the time 
permitted, as described in the sections of this Prospectus captioned "Right 
to Cancel Individual Retirement Annuity" and "Right to Cancel All Other 
Contracts," will have their exchanged contract automatically reinstated as of 
the date of cancellation. The refunded amount will be applied as the new 
current Accumulated Value under the reinstated contract, which may be more or 
less than it would have been had no exchange and reinstatement occurred. The 
refunded amount will be allocated initially among the Fixed Account and 
Sub-Accounts of the reinstated contract in the same proportion that the value 
in the Fixed Account and the value in each Sub-Account bore to the 
transferred Accumulated Value on the date of the exchange of the contract for 
the new Contract. For purposes of calculating any surrender charge under the 
reinstated contract, the reinstated contract will be deemed to have been 
issued and to have received past purchase payments as if there had been no 
exchange.
    

                         PERFORMANCE INFORMATION

Performance information for a Sub-Account may be compared, in reports and
promotional literature, to certain indices described in the prospectus under
"PERFORMANCE INFORMATION." In addition, the Company may provide advertising,
sales literature, periodic publications or other material information on various
topics of interest to Owners and prospective Owners. These topics may include
the relationship between sectors of the economy and the economy as a whole and
its effect on various securities markets, investment strategies 

                                       7

and techniques (such as value investing, market timing, dollar cost 
averaging, asset allocation, constant ratio transfer and account 
rebalancing), the advantages and disadvantages of investing in tax-deferred 
and taxable investments, customer profiles and hypothetical purchase and 
investment scenarios, financial management and tax and retirement planning, 
and investment alternatives to certificates of deposit and other financial 
instruments, including comparisons between the Contract and the 
characteristics of and market for such financial instruments. Total return 
data and supplemental total return information may be advertised based on the 
period of time that an underlying Sub-Account has been in existence and the 
period of time that an Underlying Fund has been in existence, even if longer 
than the period of time that the Contract has been offered. The results for 
any period prior to a Contract being offered will be calculated as if the 
Contract had been offered during that period of time, with all charges 
assumed to be those applicable to the Contract. Contracts funded by Fulcrum 
Separate Account have been offered to the public since 1997.

TOTAL RETURN
   
"Total Return" refers to the total of the income generated by an investment 
in a Sub-Account and of the changes of value of the principal invested (due 
to realized and unrealized capital gains or losses) for a specified period, 
reduced by the Sub-Account's asset charge and any applicable surrender charge 
which would be assessed upon complete withdrawal of the investment.
    

Total Return figures are calculated by standardized methods prescribed by 
rules of the Securities and Exchange Commission (the "SEC"). The quotations 
are computed by finding the average annual compounded rates of return over 
the specified periods that would equate the initial amount invested to the 
ending redeemable values, according to the following formula:


           (n)
   P(1 + T)    = ERV

   Where:  P  = a hypothetical initial payment to the Variable Account of $1,000

           T  = average annual total return

           n  = number of years

         ERV  = the ending redeemable value of the $1,000 payment at the end 
                of the specified period

   
Quotations of average annual total return for the periods that the 
Sub-Accounts and for periods that the Underlying Funds have been in existence 
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 1.45%, the $30 annual Contract fee and the surrender charge 
which would be assessed if the investment were completely withdrawn at the 
end of the specified period, according to the following schedule. See Tables 
1A and 2A.

* Subject to the maximum limit described in the Prospectus.

   
No surrender charge is deducted upon expiration of the periods specified 
above. In all calendar years, an amount equal to the greater of: (a) 15% of 
the Accumulated Value, (b) cumulative earnings (Accumulated Value less total 
gross payments not previously withdrawn), or (c) the life expectancy 
distribution, is not subject to the surrender charge.
    

SUPPLEMENTAL TOTAL RETURN INFORMATION

The Supplemental Total Return information in this section refers to the total 
of the income generated by an investment in a Sub-Account and of the changes 
of value of the principal invested (due to realized and unrealized capital 
gains or losses) for a specified period reduced by the Sub-Account's asset 
charges. It is assumed, however, that the investment is NOT withdrawn at the 
end of each period.

The quotations of Supplemental Total Return are computed by finding the 
average annual compounded rates of return over the specified periods that 
would equate the initial amount invested to the ending values, according to 
the following formula:

             (n)
     P(1 + T)    = EV

   Where:  P  = a hypothetical initial payment to the Variable Account of $1,000

           T  = average annual total return

           n  = number of years

          EV  = the ending value of the $1,000 payment at the end of the 
                specified period

   
Quotations of supplemental average total return for the periods that the 
Sub-Accounts and for periods that the Underlying Funds have been in existence 
are calculated in exactly the same manner as total return information and for 
the same periods of time except that they do not reflect the surrender charge 
and assume that the Contract is not surrendered at the end of the periods 
shown. The calculation of supplemental total return does not include the 
deduction of the $30 annual Contract fee. See Tables 1B and 2B below.

YIELD AND EFFECTIVE YIELD - THE MONEY MARKET SUB-ACCOUNT

   
Set forth below is yield and effective yield information for the Money Market
Sub-Account for the seven-day period ended December 31, 1998:
    

   
                        Yield                     3.61%
                        Effective Yield           3.68%
    

The yield and effective yield figures are calculated by standardized methods 
prescribed by rules of the SEC. Under those methods, the yield quotation is 
computed by determining the net change (exclusive of capital changes) in the 
value of a hypothetical pre-existing account having a balance of one 
accumulation unit of the Sub-Account at the beginning of the period, dividing 
the difference by the value of the account at the beginning of the same 
period to obtain the base period return, and then multiplying the return for 
a seven-day base period by (365/7), with the resulting yield carried to the 
nearest hundredth of one percent.

The Money Market Sub-Account computes effective yield by compounding the 
unannualized base period return by using the formula:

                                                       (365/7)
            Effective Yield = [(base period return + 1)       ] - 1

The calculations of yield and effective yield reflect the $30 Contract fee.

This chart compares the accumulation of a $50,000 initial investment into a 
non-qualified annuity contract and a conventional savings plan. Contributions 
to the non-qualified annuity contract and the conventional savings plan are 
made after tax. Only the gain in the non-qualified annuity contract will be 
subject to income tax in a taxable lump sum withdrawal. The chart assumes a 
37.1% federal marginal tax rate and an 8% annual return. The 37.1% federal 
marginal tax is based on a marginal tax rate of 36%, representative of the 
target market, adjusted to reflect a decrease of $3 of itemized deductions 
for each $100 of income over $117,950. Tax rates are subject to change as is 
the tax-deferred treatment of the Contract. Income on non-qualified annuity 
contracts is taxed as ordinary income upon withdrawal. A 10% tax penalty may 
apply to early withdrawals. See "Federal Income Taxes" in the Prospectus.

   
The chart does not reflect the following charges and expenses under the 
contract: 1.25% for mortality and expense risk; 0.20% administration charges; 
7% maximum surrender charge; and $30 annual Contract fee. The tax-deferred 
accumulation would be reduced if these charges were reflected. No implication 
is intended by the use of these assumptions that the return shown is 
guaranteed in any way or that the return shown represents an average or 
expected rate of return over the period of the Contract. (IMPORTANT -- THIS 
IS NOT AN ILLUSTRATION OF YIELD OR RETURN.)

Unlike savings plans, contributions to non-qualified annuity contracts 
provide tax-deferred treatment on earnings. In addition, contributions to 
tax-deferred retirement annuities are not subject to current tax in the year 
of contribution. When monies are received from a non-qualified annuity 
contract (and you have many different options on how you receive your funds), 
they are subject to income tax. At the time of receipt, if the person 
receiving the monies is retired, not working or has additional tax 
exemptions, these monies may be taxed at a lesser rate.

                       REPORT OF INDEPENDENT ACCOUNTANTS
 
To the Board of Directors and Shareholder of
Allmerica Financial Life Insurance and Annuity Company
 
In our opinion, the accompanying consolidated balance sheets and the related
consolidated statements of income, comprehensive income, shareholder's equity
and cash flows present fairly, in all material respects, the financial position
of Allmerica Financial Life Insurance and Annuity Company (the "Company") at
December 31, 1998 and 1997, and the results of their operations and their cash
flows for each of the three years in the period ended December 31, 1998 in
conformity with generally accepted accounting principles. These financial
statements are the responsibility of the Company's management; our
responsibility is to express an opinion on these financial statements based on
our audits. We conducted our audits of these statements in accordance with
generally accepted auditing standards which require that we plan and perform the
audit to obtain reasonable assurance about whether the financial statements are
free of material misstatement. An audit includes examining, on a test basis,
evidence supporting the amounts and disclosures in the financial statements,
assessing the accounting principles used and significant estimates made by
management, and evaluating the overall financial statement presentation. We
believe that our audits provide a reasonable basis for the opinion expressed
above.

The preparation of financial statements in conformity with generally accepted
accounting principles requires the Company to make estimates and assumptions
that affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amount of revenues and expenses during the reporting period. Actual
results could differ from those estimates.
 
B.  VALUATION OF INVESTMENTS
 
In accordance with the provisions of Statement of Financial Accounting Standards
No. 115 ("Statement No. 115"), "Accounting for Certain Investments in Debt and
Equity Securities", the Company is required to classify its investments into one
of three categories: held-to-maturity, available-for-sale or trading. The
Company determines the appropriate classification of debt securities at the time
of purchase and re-evaluates such designation as of each balance sheet date.
 
Marketable equity securities and debt securities are classified as
available-for-sale. Available-for-sale securities are carried at fair value,
with the unrealized gains and losses, net of tax, reported in a separate
component of shareholder's equity. The amortized cost of debt securities is
adjusted for amortization of premiums and accretion of discounts to maturity.
Such amortization is included in investment income.
 
Mortgage loans on real estate are stated at unpaid principal balances, net of
unamortized discounts and reserves. Reserves on mortgage loans are based on
losses expected by the Company to be realized on transfers of mortgage loans to
real estate (upon foreclosure), on the disposition or settlement of mortgage
loans and on mortgage loans which the Company believes may not be collectible in
full. In establishing reserves, the Company considers, among other things, the
estimated fair value of the underlying collateral.
 
Fixed maturities and mortgage loans that are delinquent are placed on
non-accrual status, and thereafter interest income is recognized only when cash
payments are received.
 
Policy loans are carried principally at unpaid principal balances.
 
During 1997, the Company adopted to a plan to dispose of all real estate assets
by the end of 1998. As of December 31, 1998, there was 1 property remaining in
the Company's real estate portfolio, which is being actively marketed. As a
result of the Plan, real estate held by the Company and real estate joint
ventures were written down to the estimated fair value less cost of disposal.
Depreciation is not recorded on this asset while it is held for disposal.
 
                                      F-6
<PAGE>
             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
Realized investment gains and losses, other than those related to separate
accounts for which the Company does not bear the investment risk, are reported
as a component of revenues based upon specific identification of the investment
assets sold. When an other-than-temporary impairment of the value of a specific
investment or a group of investments is determined, a realized investment loss
is recorded. Changes in the valuation allowance for mortgage loans are included
in realized investment gains or losses.
 
C.  FINANCIAL INSTRUMENTS
 
In the normal course of business, the Company enters into transactions involving
various types of financial instruments, including debt, investments such as
fixed maturities, mortgage loans and equity securities and investment and loan
commitments. These instruments involve credit risk and also may be subject to
risk of loss due to interest rate fluctuation. The Company evaluates and
monitors each financial instrument individually and, when appropriate, obtains
collateral or other security to minimize losses.
 
D.  CASH AND CASH EQUIVALENTS
 
Cash and cash equivalents includes cash on hand, amounts due from banks and
highly liquid debt instruments purchased with an original maturity of three
months or less.
 
E.  DEFERRED POLICY ACQUISITION COSTS
 
Acquisition costs consist of commissions, underwriting costs and other costs,
which vary with, and are primarily related to, the production of revenues.
Acquisition costs related to universal life products, variable annuities and
contractholder deposit funds are deferred and amortized in proportion to total
estimated gross profits from investment yields, mortality, surrender charges and
expense margins over the expected life of the contracts. This amortization is
reviewed annually and adjusted retrospectively when the Company revises its
estimate of current or future gross profits to be realized from this group of
products, including realized and unrealized gains and losses from investments.
Acquisition costs related to fixed annuities and other life insurance products
are deferred and amortized, generally in proportion to the ratio of annual
revenue to the estimated total revenues over the contract periods based upon the
same assumptions used in estimating the liability for future policy benefits.
 
Deferred acquisition costs for each product are reviewed to determine if they
are recoverable from future income, including investment income. If such costs
are determined to be unrecoverable, they are expensed at the time of
determination. Although realization of deferred policy acquisition costs is not
assured, the Company believes it is more likely than not that all of these costs
will be realized. The amount of deferred policy acquisition costs considered
realizable, however, could be reduced in the near term if the estimates of gross
profits or total revenues discussed above are reduced. The amount of
amortization of deferred policy acquisition costs could be revised in the near
term if any of the estimates discussed above are revised.
 
F.  SEPARATE ACCOUNTS
 
Separate account assets and liabilities represent segregated funds administered
and invested by the Company for the benefit of certain pension, variable annuity
and variable life insurance contractholders. Assets consist principally of
bonds, common stocks, mutual funds, and short-term obligations at market value.
The investment income, gains and losses of these accounts generally accrue to
the contractholders and, therefore, are not included in the Company's net
income. Appreciation and depreciation of the Company's interest in the separate
accounts, including undistributed net investment income, is reflected in
shareholder's equity or net investment income.
 
G.  POLICY LIABILITIES AND ACCRUALS
 
Future policy benefits are liabilities for life, disability income and annuity
products. Such liabilities are established in amounts adequate to meet the
estimated future obligations of policies in force. The liabilities associated
with traditional life insurance products are computed using the net level
premium method for
 
                                      F-7
<PAGE>
             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
individual life and annuity policies, and are based upon estimates as to future
investment yield, mortality and withdrawals that include provisions for adverse
deviation. Future policy benefits for individual life insurance and annuity
policies are computed using interest rates ranging from 3% to 6% for life
insurance and 3 1/2% to 9 1/2% for annuities. Mortality, morbidity and
withdrawal assumptions for all policies are based on the Company's own
experience and industry standards. Liabilities for universal life include
deposits received from customers and investment earnings on their fund balances,
less administrative charges. Universal life fund balances are also assessed
mortality and surrender charges.
 
Individual disability income benefit liabilities for active lives are estimated
using the net level premium method, and assumptions as to future morbidity,
withdrawals and interest which provide a margin for adverse deviation. Benefit
liabilities for disabled lives are estimated using the present value of benefits
method and experience assumptions as to claim terminations, expenses and
interest.
 
Liabilities for outstanding claims, losses and loss adjustment expenses are
estimates of payments to be made for reported claims and estimates of claims
incurred but not reported for individual life and disability income policies.
These estimates are continually reviewed and adjusted as necessary; such
adjustments are reflected in current operations.
 
Contractholder deposit funds and other policy liabilities include
investment-related products and consist of deposits received from customers and
investment earnings on their fund balances.
 
All policy liabilities and accruals are based on the various estimates discussed
above. Although the adequacy of these amounts cannot be assured, the Company
believes that it is more likely than not that policy liabilities and accruals
will be sufficient to meet future obligations of policies in force. The amount
of liabilities and accruals, however, could be revised in the near term if the
estimates discussed above are revised.
 
H.  PREMIUM AND FEE REVENUE AND RELATED EXPENSES
 
Premiums for individual life and individual annuity products, excluding
universal life and investment-related products, are considered revenue when due.
Individual disability income insurance premiums are recognized as revenue over
the related contract periods. The unexpired portion of these premiums is
recorded as unearned premiums. Benefits, losses and related expenses are matched
with premiums, resulting in their recognition over the lives of the contracts.
This matching is accomplished through the provision for future benefits,
estimated and unpaid losses and amortization of deferred policy acquisition
costs. Revenues for investment-related products consist of net investment income
and contract charges assessed against the fund values. Related benefit expenses
primarily consist of net investment income credited to the fund values after
deduction for investment and risk charges. Revenues for universal life and group
variable universal life products consist of net investment income, with
mortality, administration and surrender charges assessed against the fund
values. Related benefit expenses include universal life benefit claims in excess
of fund values and net investment income credited to universal life fund values.
Certain policy charges that represent compensation for services to be provided
in future periods are deferred and amortized over the period benefited using the
same assumptions used to amortize capitalized acquisition costs.
 
I.  FEDERAL INCOME TAXES
 
AFC and its domestic subsidiaries file a consolidated United States federal
income tax return. Entities included within the consolidated group are
segregated into either a life insurance or non-life insurance company subgroup.
The consolidation of these subgroups is subject to certain statutory
restrictions on the percentage of eligible non-life tax losses that can be
applied to offset life insurance company taxable income.
 
The Board of Directors has delegated to AFC management, the development and
maintenance of appropriate federal income tax allocation policies and
procedures, which are subject to written agreement between the
 
                                      F-8
<PAGE>
             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
companies. The Federal income tax for all subsidiaries in the consolidated
return of AFC is calculated on a separate return basis. Any current tax
liability is paid to AFC. Tax benefits resulting from taxable operating losses
or credits of AFC's subsidiaries are not reimbursed to the subsidiary until such
losses or credits can be utilized by the subsidiary on a separate return basis.
 
Deferred income taxes are generally recognized when assets and liabilities have
different values for financial statement and tax reporting purposes, and for
other temporary taxable and deductible differences as defined by Statement of
Financial Accounting Standards No. 109, "Accounting for Income Taxes" (Statement
No. 109). These differences result primarily from policy reserves, policy
acquisition expenses, and unrealized appreciation or depreciation on
investments.
 
J.  NEW ACCOUNTING PRONOUNCEMENTS
 
In June 1998, the Financial Accounting Standards Board ("FASB") issued Statement
of Financial Accounting Standards No. 133, "Accounting for Derivative
Instruments and Hedging Activities" ("Statement No. 133"), which establishes
accounting and reporting standards for derivative instruments. Statement No. 133
requires that an entity recognize all derivatives as either assets or
liabilities at fair value in the statement of financial position, and
establishes special accounting for the following three types of hedges; fair
value hedges, cash flow hedges, and hedges of foreign currency exposures of net
investment in foreign operations. This statement is effective for fiscal years
beginning after June 15, 1999. The Company is currently assessing the impact of
adoption of Statement No. 133.
 
In March 1998, the American Institute of Certified Public Accountants ("AICPA")
issued Statement of Position 98-1, "Accounting for the Cost of Computer Software
Developed or Obtained for Internal Use" ("SoP 98-1"). SoP 98-1 requires that
certain costs incurred in developing internal-use computer software be
capitalized and provides guidance for determining whether computer software is
to be considered for internal use. This statement is effective for fiscal years
beginning after December 15, 1998. In the second quarter, the Company adopted
SoP 98-1 effective January 1, 1998, resulting in an increase in pre-tax income
of $9.8 million through December 31, 1998. The adoption of SoP 98-1 did not have
a material effect on the results of operations or financial position for the
three months ended March 31, 1998.
 
In December 1997, the American Institute of Certified Public Accountants
("AICPA") issued Statement of Position 97-3, "Accounting by Insurance and Other
Enterprises for Insurance-Related Assessments" ("SoP 97-3"). SoP 97-3 provides
guidance when a liability should be recognized for guaranty fund and other
assessments and how to measure the liability. This statement allows for the
discounting of the liability if the amount and timing of the cash payments are
fixed and determinable. In addition, it provides criteria for when an asset may
be recognized for a portion or all of the assessment liability or paid
assessment that can be recovered through premium tax offsets or policy
surcharges. This statement is effective for fiscal years beginning after
December 15, 1998. The Company believes that the adoption of this statement will
not have a material effect on the results of operations or financial position.
 
In June 1997, the FASB issued Statement No. 131, "Disclosures About Segments of
an Enterprise and Related Information" ("Statement No. 131"). This statement
establishes standards for the way that public enterprises report information
about operating segments in annual financial statements and requires that
selected information about those operating segments be reported in interim
financial statements. This statement supersedes Statement No. 14, "Financial
Reporting for Segments of a Business Enterprise". Statement No. 131 requires
that all public enterprises report financial and descriptive information about
their reportable operating segments. Operating segments are defined as
components of an enterprise about which separate financial information is
available that is evaluated regularly by the chief operating decision maker in
deciding how to allocate resources and in assessing performance. This statement
is effective for fiscal years

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
beginning after December 15, 1997. AFLIAC consists of one segment, Allmerica
Financial Services, which underwrites and distributes variable annuities and
variable universal life via retail channels.
 
In June 1997, the FASB also issued Statement No. 130, "Reporting Comprehensive
Income" ("Statement No. 130"), which established standards for the reporting and
display of comprehensive income and its components in a full set of
general-purpose financial statements. All items that are required to be
recognized under accounting standards as components of comprehensive income are
to be reported in a financial statement that is displayed with the same
prominence as other financial statements. This statement stipulates that
comprehensive income reflect the change in equity of an enterprise during a
period from transactions and other events and circumstances from non-owner
sources. This statement is effective for fiscal years beginning after December
15, 1997. The Company adopted Statement No. 130 for the first quarter of 1998,
which resulted primarily in reporting unrealized gains and losses on investments
in debt and equity securities in comprehensive income.
 
2.  SIGNIFICANT TRANSACTIONS
 
Effective January 1, 1998, the Company entered into an agreement with a highly
rated reinsurer to reinsure the mortality risk on the universal life and
variable universal life blocks of business. The agreement does not have a
material effect on the results of operations or financial position of the
Company.
 
On April 14, 1997, the Company entered into an agreement in principle to cede
substantially all of the Company's individual disability income line of business
under a 100% coinsurance agreement with a highly rated reinsurer. The
coinsurance agreement became effective October 1, 1997. The transaction has
resulted in the recognition of a $53.9 million pre-tax loss in the first quarter
of 1997.
 
During 1998, 1997 and 1996 , SMAFCO contributed $21.0 million, $40.6 million and
$22.0 million, respectively, of additional paid-in capital to the Company. The
nature of the 1997 contribution was $19.2 million in cash and $21.4 million in
other assets including Somerset Square, Inc.

(1) Amortized cost for fixed maturities and cost for equity securities.
 
In connection with AFLIAC's voluntary withdrawal of its license in New York,
AFLIAC agreed with the New York Department of Insurance to maintain, through a
custodial account in New York, a security deposit, the market value of which
will at all times equal 102% of all outstanding liabilities of AFLIAC for New
York policyholders, claimants and creditors. At December 31, 1998, the amortized
cost and market value of these assets on deposit in New York were $268.5 million
and $284.1 million, respectively. At December 31, 1997, the amortized cost and
market value of assets on deposit were $276.8 million and $291.7 million,
respectively. In addition, fixed maturities, excluding those securities on
deposit in New York, with an amortized cost of $4.2 million were on deposit with
various state and governmental authorities at December 31, 1998 and 1997.
 
There were no contractual fixed maturity investment commitments at December 31,
1998 and 1997, respectively.
 
The amortized cost and fair value by maturity periods for fixed maturities are
shown below. Actual maturities may differ from contractual maturities because
borrowers may have the right to call or prepay obligations with or without call
or prepayment penalties, or the Company may have the right to put or sell the
obligations back to the issuers. Mortgage backed securities are included in the
category representing their ultimate maturity.

B.  MORTGAGE LOANS AND REAL ESTATE
 
AFLIAC's mortgage loans and real estate are diversified by property type and
location. Real estate investments have been obtained primarily through
foreclosure. Mortgage loans are collateralized by the related properties and
generally are no more than 75% of the property's value at the time the original
loan is made.
 
The carrying values of mortgage loans and real estate investments net of
applicable reserves were as follows:

Reserves for mortgage loans were $3.3 million and $9.4 million at December 31,
1998 and 1997, respectively.
 
During 1997, the Company committed to a plan to dispose of all real estate
assets by the end of 1998. At December 31, 1998, there was 1 property remaining
in the Company's real estate portfolio, which is being actively marketed. As a
result of the Plan, during 1997, real estate assets with a carrying amount of
$15.7 million were written down to the estimated fair value less cost to sell of
$12.0 million, and a net realized investment loss of $3.7 million was
recognized. Depreciation was not recorded on these assets while they were held
for disposal.
 
There were no non-cash investing activities, including real estate acquired
through foreclosure of mortgage loans, in 1998 and 1997. During 1996, non-cash
investing activities included real estate acquired through foreclosure of
mortgage loans, which had a fair value of $0.9 million.
 
There were no contractual commitments to extend credit under commercial mortgage
loan agreements at December 31, 1998. These commitments generally expire within
one year.
 
Mortgage loans and real estate investments comprised the following property
types and geographic regions:

At December 31, 1998, scheduled mortgage loan maturities were as follows: 1999
- -- $24.8 million; 2000 -- $43.5 million; 2001 -- $6.6 million; 2002 -- $11.5
million; 2003 -- $0.6 million; and $143.0 million thereafter. Actual maturities
could differ from contractual maturities because borrowers may have the right to
prepay obligations with or without prepayment penalties and loans may be
refinanced. During 1998, the Company did not refinance any mortgage loans based
on terms which differed from those granted to new borrowers.

There were no mortgage loans or fixed maturities on non-accrual status at
December 31, 1998. The effect of non-accruals, compared with amounts that would
have been recognized in accordance with the original terms of the investment,
had no impact in 1998 and 1997, and reduced net income by $0.1 million in 1996.
 
The payment terms of mortgage loans may from time to time be restructured or
modified. The investment in restructured mortgage loans, based on amortized
cost, amounted to $12.6 million, $21.1 million and $25.4 million at December 31,
1998, 1997 and 1996, respectively. Interest income on restructured mortgage
loans that would have been recorded in accordance with the original terms of
such loans amounted to $1.4 million, $1.9 million and $3.6 million in 1998,
1997, and 1996, respectively. Actual interest income on these loans included in
net investment income aggregated $1.8 million, $2.1 million and $2.2 million in
1998, 1997, and 1996, respectively.

5.  FAIR VALUE DISCLOSURES OF FINANCIAL INSTRUMENTS
 
Statement No. 107, "Disclosures about Fair Value of Financial Instruments"
("Statement No, 107"), requires disclosure of fair value information about
certain financial instruments (insurance contracts, real estate, goodwill and
taxes are excluded) for which it is practicable to estimate such values, whether
or not these instruments are included in the balance sheet. The fair values
presented for certain financial instruments are estimates which, in many cases,
may differ significantly from the amounts which could be realized upon immediate
liquidation. In cases where market prices are not available, estimates of fair
value are based on discounted cash flow analyses, which utilize current interest
rates for similar financial instruments, which have comparable terms and credit
quality.
 
The following methods and assumptions were used to estimate the fair value of
each class of financial instruments:
 
CASH AND CASH EQUIVALENTS
 
For these short-term investments, the carrying amount approximates fair value.
 
FIXED MATURITIES
 
Fair values are based on quoted market prices, if available. If a quoted market
price is not available, fair values are estimated using independent pricing
sources or internally developed pricing models using discounted cash flow
analyses.
 
EQUITY SECURITIES
 
Fair values are based on quoted market prices, if available. If a quoted market
price is not available, fair values are estimated using independent pricing
sources or internally developed pricing models.
 
MORTGAGE LOANS
 
Fair values are estimated by discounting the future contractual cash flows using
the current rates at which similar loans would be made to borrowers with similar
credit ratings. The fair value of below investment grade mortgage loans is
limited to the lesser of the present value of the cash flows or book value.
 
                                      F-16
<PAGE>
             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
POLICY LOANS
 
The carrying amount reported in the balance sheet approximates fair value since
policy loans have no defined maturity dates and are inseparable from the
insurance contracts.
 
INVESTMENT CONTRACTS (WITHOUT MORTALITY FEATURES)
 
Fair values for the Company's liabilities under investment type contracts are
estimated based on current surrender values.
 
The estimated fair values of the financial instruments were as follows:

                                                              --------   --------
</TABLE>
 
Gross deferred income tax liabilities totaled $291.7 million and $253.7 million
at December 31, 1998 and 1997, respectively. Gross deferred income tax assets
totaled $212.9 million and $177.8 at December 31, 1998 and 1997, respectively.
 
The Company believes, based on its recent earnings history and its future
expectations, that the Company's taxable income in future years will be
sufficient to realize all deferred tax assets. In determining the adequacy of
future income, the Company considered the future reversal of its existing
temporary differences and available tax planning strategies that could be
implemented, if necessary.
 
The Company's federal income tax returns are routinely audited by the IRS, and
provisions are routinely made in the financial statements in anticipation of the
results of these audits. The IRS has examined the consolidated group's federal
income tax returns through 1994. The Company has appealed certain adjustments
proposed by the IRS with respect to the consolidated group's federal income tax
returns for 1992, 1993, and 1994. Also, certain adjustments proposed by the IRS
with respect to FAFLIC/AFLIAC's federal income tax returns for 1982 and 1983
remain unresolved. If upheld, these adjustments would result in additional
payments; however, the Company will vigorously defend its position with respect
to these adjustments. In the Company's opinion, adequate tax liabilities have
been established for all years. However, the amount of these tax liabilities
could be revised in the near term if estimates of the Company's ultimate
liability are revised.
 
7.  RELATED PARTY TRANSACTIONS
 
The Company has no employees of its own, but has agreements under which FAFLIC
provides management, space and other services, including accounting, electronic
data processing, human resources, legal and other staff functions. Charges for
these services are based on full cost including all direct and indirect overhead
costs, and amounted to $145.4 million and $124.1 million in 1998 and 1997. The
net amounts payable to FAFLIC and affiliates for accrued expenses and various
other liabilities and receivables were $16.4 million and $15.0 million at
December 31, 1998 and 1997, respectively.
 
8.  DIVIDEND RESTRICTIONS
 
Delaware has enacted laws governing the payment of dividends to stockholders by
insurers. These laws affect the dividend paying ability of the Company.
 
Pursuant to Delaware's statute, the maximum amount of dividends and other
distributions that an insurer may pay in any twelve month period, without the
prior approval of the Delaware Commissioner of Insurance, is limited to the
greater of (i) 10% of its policyholders' surplus as of the preceding December 31
or (ii) the individual company's statutory net gain from operations for the
preceding calendar year (if such insurer is a
 
                                      F-18

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
life company) or its net income (not including realized capital gains) for the
preceding calendar year (if such insurer is not a life company). Any dividends
to be paid by an insurer, whether or not in excess of the aforementioned
threshold, from a source other than statutory earned surplus would also require
the prior approval of the Delaware Commissioner of Insurance.
 
No dividends were declared by the Company during 1998, 1997 and 1996. During
1999, AFLIAC could pay dividends of $26.1 million to FAFLIC without prior
approval.
 
9.  REINSURANCE
 
In the normal course of business, the Company seeks to reduce the loss that may
arise from events that cause unfavorable underwriting results by reinsuring
certain levels of risk in various areas of exposure with other insurance
enterprises or reinsurers. Reinsurance transactions are accounted for in
accordance with the provisions of Statement No. 113, "Accounting and Reporting
for Reinsurance of Short-Duration and Long-Duration Contracts" ("Statement No.
113").
 
The Company reinsures 100% of its traditional individual life and certain blocks
of its universal life business, substantially all of its disability income
business, and effective January 1, 1998, the mortality risk on the variable
universal life and remaining universal life blocks of business in-force at
December 31, 1997.
 
Amounts recoverable from reinsurers are estimated in a manner consistent with
the claim liability associated with the reinsured policy. Reinsurance contracts
do not relieve the Company from its obligations to policyholders. Failure of
reinsurers to honor their obligations could result in losses to the Company;
consequently, allowances are established for amounts deemed uncollectible. The
Company determines the appropriate amount of reinsurance based on evaluation of
the risks accepted and analyses prepared by consultants and reinsurers and on
market conditions (including the availability and pricing of reinsurance). The
Company also believes that the terms of its reinsurance contracts are consistent
with industry practice in that they contain standard terms with respect to lines
of business covered, limit and retention, arbitration and occurrence. Based on
its review of its reinsurers' financial statements and reputations in the
reinsurance marketplace, the Company believes that its reinsurers are
financially sound.
 
Amounts recoverable from reinsurers at December 31, 1998 and 1997 for the
disability income business were $230.8 million and $216.1 million, respectively,
traditional life were $11.4 million and $15.2 million, respectively, and
universal and variable universal life were $65.8 million and $19.8 million,
respectively.
 
The effects of reinsurance were as follows:

On October 1, 1997, the Company revised the mortality assumptions for universal
life and variable universal life product lines. These revisions resulted in a
$50.3 million recapitalization of deferred policy acquisition costs.
 
11.  LIABILITIES FOR INDIVIDUAL DISABILITY INCOME BENEFITS
 
The Company regularly updates its estimates of liabilities for future policy
benefits and outstanding claims, losses and loss adjustment expenses as new
information becomes available and further events occur which may impact the
resolution of unsettled claims. Changes in prior estimates are recorded in
results of operations in the year such changes are determined to be needed.
 
The liability for future policy benefits and outstanding claims, losses and loss
adjustment expenses related to the Company's disability income business was
$233.3 million and $219.9 million at December 31, 1998 and 1997. Due to the
reinsurance agreement whereby the Company has ceded substantially all of its
disability income business to a highly rated reinsurer, the Company believes
that no material adverse development of losses will occur. However, the amount
of the liabilities could be revised in the near term if the estimates are
revised.
 
12.  CONTINGENCIES
 
REGULATORY AND INDUSTRY DEVELOPMENTS
 
Unfavorable economic conditions may contribute to an increase in the number of
insurance companies that are under regulatory supervision. This may result in an
increase in mandatory assessments by state guaranty funds, or voluntary payments
by solvent insurance companies to cover losses to policyholders of insolvent or
rehabilitated companies. Mandatory assessments, which are subject to statutory
limits, can be partially

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
recovered through a reduction in future premium taxes in some states. The
Company is not able to reasonably estimate the potential effect on it of any
such future assessments or voluntary payments.
 
LITIGATION
 
In July 1997, a lawsuit on behalf of a putative class was instituted in
Louisiana against AFC and certain of its subsidiaries including AFLIAC, by
individual plaintiffs alleging fraud, unfair or deceptive acts, breach of
contract, misrepresentation, and related claims in the sale of life insurance
policies. In October 1997, plaintiffs voluntarily dismissed the Louisiana suit
and filed a substantially similar action in Federal District Court in Worcester,
Massachusetts. In early November 1998, AFC and the plaintiffs entered into a
settlement agreement, to which the court granted preliminary approval on
December 4, 1998. A hearing was held on March 19, 1999 to consider final
approval of the settlement agreement. A decision by the court is expected to be
rendered in the near future. Accordingly, AFLIAC recognized a $21.0 million
pre-tax expense during the third quarter of 1998 related to this litigation.
Although the Company believes that this expense reflects appropriate recognition
of its obligation under the settlement, this estimate assumes the availability
of insurance coverage for certain claims, and the estimate may be revised based
on the amount of reimbursement actually tendered by AFC's insurance carriers, if
any, and based on changes in the Company's estimate of the ultimate cost of the
benefits to be provided to members of the class.
 
The Company has been named a defendant in various legal proceedings arising in
the normal course of business. In the Company's opinion of, based on the advice
of legal counsel, the ultimate resolution of these proceedings will not have a
material effect on the Company's financial statements. However, liabilities
related to these proceedings could be established in the near term if estimates
of the ultimate resolution of these proceedings are revised.
 
YEAR 2000
 
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.
 
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.
 
13.  STATUTORY FINANCIAL INFORMATION
 
The Company is required to file annual statements with state regulatory
authorities prepared on an accounting basis prescribed or permitted by such
authorities (statutory basis). Statutory surplus differs from shareholder's
equity reported in accordance with generally accepted accounting principles
primarily because policy acquisition costs are expensed when incurred,
investment reserves are based on different assumptions, life insurance reserves
are based on different assumptions and income tax expense reflects only taxes
paid or currently payable. Statutory net income and surplus are as follows:

To the Board of Directors of Allmerica Financial Life Insurance and Annuity
Company and the Contractowners of Fulcrum Separate Account of Allmerica
Financial Life Insurance and Annuity Company
 
In our opinion, the accompanying statements of assets and liabilities, and the
related statements of operations and changes in net assets present fairly, in
all material respects, the financial position of each of the Sub-Accounts
constituting the Fulcrum Separate Account of Allmerica Financial Life Insurance
and Annuity Company at December 31, 1998, the results of each of their
operations and the changes in each of their net assets for each of the periods
indicated, in conformity with generally accepted accounting principles. These
financial statements are the responsibility of Allmerica Financial Life
Insurance and Annuity Company's management; our responsibility is to express an
opinion on these financial statements based on our audits. We conducted our
audits of these financial statements in accordance with generally accepted
auditing standards which require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements, assessing the
accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits, which included confirmation of securities at December 31, 1998 by
correspondence with the Funds, provide a reasonable basis for the opinion
expressed above.

                            FULCRUM SEPARATE ACCOUNT
 
                         NOTES TO FINANCIAL STATEMENTS
 
NOTE 1 -- ORGANIZATION
 
    The Fulcrum Separate Account (the Separate Account) is a separate investment
account of Allmerica Financial Life Insurance and Annuity Company (the Company),
established on November 15, 1996 for the purpose of separating from the general
assets of the Company those assets used to fund certain variable annuity
contracts issued by the Company. The Company is a wholly-owned subsidiary of
First Allmerica Financial Life Insurance Company (First Allmerica). First
Allmerica is a wholly-owned subsidiary of Allmerica Financial Corporation (AFC).
Under applicable insurance law, the assets and liabilities of the Separate
Account are clearly identified and distinguished from the other assets and
liabilities of the Company. The Separate Account cannot be charged with
liabilities arising out of any other business of the Company.
 
    The Separate Account is registered as a unit investment trust under the
Investment Company Act of 1940, as amended (the 1940 Act). The Separate Account
currently offers fifteen Sub-Accounts under the Fulcrum variable annuity
contracts. Each Sub-Account invests exclusively in a corresponding portfolio of
The Fulcrum Trust (formerly The Palladian-SM- Trust) or the Allmerica Investment
Trust (AIT) managed by Allmerica Financial Investment Management Services, Inc.
(AFIMS) (successor to Allmerica Investment Management Company, Inc.), a
wholly-owned subsidiary of First Allmerica; or of the AIM Variable Insurance
Funds, Inc. (AVIF) managed by A I M Advisors, Inc.; or of the Delaware Group
Premium Fund, Inc. (DGPF) managed by Delaware Management Company; or of the
Lazard Retirement Series, Inc. (Lazard) managed by Lazard Asset Management; or
of the MFS-Registered Trademark- Variable Insurance Trust (MFS Trust) managed by
Massachusetts Financial Services Company; or of the Oppenheimer Variable Account
Funds (Oppenheimer) managed by OppenheimerFunds-SM-, Inc.; or of the PBHG
Insurance Series Fund, Inc. (PBHG) managed by Pilgrim Baxter & Associates, Ltd.
The Fulcrum Trust, AIT, AVIF, DGPF, Lazard, MFS Trust, Oppenheimer and PBHG (the
Funds) are open-end, management investment companies registered under the 1940
Act.
 
    The Separate Account funds 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 Section 401, 403, or 408, of the Internal Revenue Code (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 according to whether they are made from a
qualified contract or a non-qualified contract.
 
    At a meeting of shareholders held on June 8, 1998, shareholders of the
Global Strategic Income Portfolio changed the portfolio's investment objective
to reduce the global emphasis, approved new non-fundamental investment policies
consistent with the new investment objective and changed the name of the
Portfolio to the Strategic Income Portfolio.
 
    Certain prior year balances have been reclassified to conform with current
year presentation.
 
NOTE 2 -- SIGNIFICANT ACCOUNTING POLICIES
 
    INVESTMENTS -- Security transactions are recorded on the trade date.
Investments held by the Sub-Accounts are stated at the net asset value per share
of the respective investment portfolio of the Funds. Net realized gains and
losses on securities sold are determined using the average cost method.
Dividends and capital gain distributions are recorded on the ex-dividend date
and are reinvested in additional shares of the respective investment portfolio
of the Funds at net asset value.

    FEDERAL INCOME TAXES -- The Company is taxed as a "life insurance company"
under Subchapter L of the Code and files a consolidated federal income tax
return with First Allmerica. The Company anticipates no tax liability resulting

taxes has been charged against the Separate Account.

NOTE 6 -- DIVERSIFICATION REQUIREMENTS
 
    Under the provisions of Section 817(h) of the Code, a variable annuity
contract, other than a contract issued in connection with certain types of
employee benefit plans, will not be treated as an annuity contract for federal
income tax purposes for any period for which the investments of the segregated
asset account on which the contract is based are not adequately diversified. The
Code provides that the "adequately diversified" requirement may be met if the
underlying investments satisfy either a statutory safe harbor test or
diversification requirements set forth in regulations issued by the Secretary of
the Treasury.
 
    The Internal Revenue Service has issued regulations under Section 817(h) of
the Code. The Company believes that the Separate Account satisfies the current
requirements of the regulations, and it intends that the Separate Account will
continue to meet such requirements.

     Each account, book or other document required to be maintained by Section
     31(a) of the 1940 Act and Rules 31a-1 to 31a-3 thereunder are maintained by

ITEM 31.  MANAGEMENT SERVICES

     The Company provides daily unit value calculations and related services for
     the Company's separate accounts.

ITEM 32.  UNDERTAKINGS

     (a)  Subject to the terms and conditions of Section 15(d) of the Securities
          Exchange Act of 1934, the undersigned registrant hereby undertakes to
          file with the Securities and Exchange Commission ("SEC") such
          supplementary and periodic information, documents, and reports as may
          be prescribed by any rule or regulation of the SEC heretofore or
          hereafter duly adopted pursuant to authority conferred in that
          section.

     (b)  The Registrant hereby undertakes to include in the prospectus a
          postcard that the applicant can remove to send for a Statement of
          Additional Information.

     (c)  The Registrant hereby undertakes to deliver a Statement of Additional
          Information promptly upon written or oral request, according to the
          requirements of Form N-4.

     (d)  Insofar as indemnification for liability arising under the 1933 Act
          may be permitted to Directors, Officers and Controlling Persons of
          Registrant under any registration statement, underwriting agreement or
          otherwise, Registrant has been advised that, in the opinion of the
          SEC, such indemnification is against public policy as expressed in the
          1933 Act and is, therefore, unenforceable.  In the event that a claim
          for indemnification against such liabilities (other than the payment
          by Registrant of expenses incurred or paid by a Director, Officer or
          Controlling Person of Registrant in the successful defense of any
          action, suit or proceeding) is asserted by such Director, Officer or
          Controlling Person in connection with the securities being registered,
          Registrant will, unless in the opinion of its counsel the matter has
          been settled by controlling precedent, submit to a court of
          appropriate jurisdiction the question whether such indemnification by
          it is against public policy as expressed in the 1933 Act and will be
          governed by the final adjudication of such issue.

<PAGE>

     (e)  The Company hereby represents that the aggregate fees and charges
          under the Contracts are reasonable in relation to the services
          rendered, expenses expected to be incurred, and risks assumed by the
          Company.

ITEM 33.  REPRESENTATIONS CONCERNING WITHDRAWAL RESTRICTIONS ON SECTION 403(b)
          PLANS AND UNDER THE TEXAS OPTIONAL RETIREMENT PROGRAM

     Registrant, a separate account of Allmerica Financial Life Insurance and
     Annuity Company ("Company"), states that it is (a) relying on Rule 6c-7
     under the 1940 Act with respect to withdrawal restrictions under the Texas
     Optional Retirement Program ("Program") and (b) relying on the "no-action"
     letter (Ref. No. IP-6-88) issued on November 28, 1988 to the American
     Council of Life Insurance, in applying the withdrawal restrictions of
     Internal Revenue Code Section 403(b)(11).  Registrant has taken the
     following steps in reliance on the letter:

     1. Appropriate disclosures regarding the redemption restrictions imposed
        by the Program and by Section 403(b)(11) have been included in the
        prospectus of each registration statement used in connection with the
        offer of the Company's variable contracts.

     2. Appropriate disclosures regarding the redemption restrictions imposed
        by the Program and by Section 403(b)(11) have been included in sales
        literature used in connection with the offer of the Company's variable
        contracts.

     3. Sales Representatives who solicit participants to purchase the variable
        contracts have been instructed to specifically bring the redemption 
        restrictions imposed by the Program and by Section 403(b)(11) to the
        attention of potential participants.

     4. A signed statement acknowledging the participant's understanding of (I)
        the restrictions on redemption imposed by the Program and by Section
        403(b)(11) and (ii) the investment alternatives available under the
        employer's arrangement will be obtained from each participant who
        purchases a variable annuity contract prior to or at the time of
        purchase.

     Registrant hereby represents that it will not act to deny or limit a
     transfer request except to the extent that a Service-Ruling or written
     opinion of counsel, specifically addressing the fact pattern involved and
     taking into account the terms of the applicable employer plan, determines
     that denial or limitation is necessary for the variable annuity contracts
     to meet the requirements of the Program or of Section 403(b).  Any transfer
     request not so denied or limited will be effected as expeditiously as
     possible.

Allmerica Financial Life Insurance and Annuity Company
440 Lincoln Street
Worcester, MA 01653


RE:   FULCRUM SEPARATE ACCOUNT OF ALLMERICA FINANCIAL
      LIFE INSURANCE AND ANNUITY COMPANY
      FILE NO.'S: 333-11377 AND 811-7799

Gentlemen:

In my capacity as Assistant Vice President and Counsel of Allmerica Financial 
Life Insurance and Annuity Company (the "Company"), I have participated in 
the preparation of this Post-Effective Amendment to the Registration 
Statement for Fulcrum Separate Account on Form N-4 under the Securities Act 
of 1933 and the Investment Company Act of 1940, with respect to the Company's 
variable annuity contracts.

I am of the following opinion:

1.  Fulcrum Separate Account is a separate account of the Company validly 
    existing pursuant to the Delaware Insurance Code and the regulations
    issued thereunder.

2.  The assets held in Fulcrum Separate Account are not chargeable with 
    liabilities arising out of any other business the Company may conduct.

3.  The variable annuity contracts, when issued in accordance with the 
    Prospectus contained in the Post-Effective Amendment to the Registration
    Statement and upon compliance with applicable local law, will be legal and
    binding obligations of the Company in accordance with their terms and 
    when sold will be legally issued, fully paid and non-assessable.

In arriving at the foregoing opinion, I have made such examination of law and 
examined such records and other documents as in my judgement are necessary or 
appropriate.

I hereby consent to the filing of this opinion as an exhibit to this 
Post-Effective Amendment to the Registration Statement for Fulcrum Separate 
Account on Form N-4 filed under the Securities Act of 1933.


                                           Very truly yours,


                                           /s/ Sheila B. St. Hilaire


                                           Sheila B. St. Hilaire
                                           Assistant Vice President and Counsel

                       CONSENT OF INDEPENDENT ACCOUNTANTS

constituting part of this Post-Effective Amendment No. 6 to the Registration 
Statement of Fulcrum Separate Account of Allmerica Financial Life Insurance
