                                    SUMMARY
 
WHAT IS THE FULCRUM FUND VARIABLE ANNUITY?
 
The Fulcrum Fund Variable Annuity contract is an insurance contract designed to
help you, the Owner, accumulate assets for your retirement or other important
financial goals on a tax-deferred basis. The Contract combines the concept of
professional money management with the attributes of an annuity contract.
Features available through the Contract include:
 
- -  a customized investment portfolio
 
- -  experienced professional investment advisers who are paid on an incentive fee
   basis
 
- -  tax deferral on earnings
 
- -  guarantees that can protect your family during the accumulation phase
 
- -  income that can be guaranteed for life
 
- -  issue age up to your 90th birthday.
 
The Contract has two phases: an accumulation phase and, if you choose to
annuitize, an annuity payout phase. During the accumulation phase, your initial
payment and any additional payments you choose to make may be allocated among
the Sub-Accounts investing in the portfolios of 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. The 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 and
until Accumulated Values are withdrawn. In addition, during the accumulation
phase, the 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 annuity benefit payments with payment amounts guaranteed by the
Company, or a combination of fixed and variable annuity benefit payments. Among
the payout options available during the annuity payout phase are:
 
- -  periodic payments for 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 guaranteed payments continuing to
   the 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.
 
                                       7

WHO ARE THE KEY PERSONS UNDER THE CONTRACT?
 
The Contract is between you, (the "Owner"), and us, Allmerica Financial Life
Insurance and Annuity Company (the "Company"). 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?

investing in the following Funds, the Guarantee Period Accounts, and the Fixed

This range of investment choices enables you to allocate your money among the

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. Values and benefits calculated on the basis of
Guarantee Period Account allocations, however, are obligations of the Company's
General Account. Amounts allocated to a Guarantee Period Account earn a
Guaranteed Interest Rate declared by the Company. The level of the Guaranteed
Interest Rate depends on the number of years of the Guarantee 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 will be
guaranteed for one year from that date. For more information about the Fixed
Account, see APPENDIX A, "MORE INFORMATION ABOUT THE FIXED ACCOUNT."

For more information, see "DESCRIPTION OF THE COMPANY, THE VARIABLE ACCOUNT AND
THE UNDERLYING FUNDS."
 
CAN I MAKE TRANSFERS AMONG THE FUNDS?
 
Yes. Prior to the Annuity Date, you may transfer among the Sub-Accounts, the
Guarantee Period Accounts, and the Fixed Account. You will incur no current
taxes on transfers while your money remains in the Contract. See "D. Transfer
Privilege." The first 12 transfers in a Contract year are guaranteed to be free
of a transfer charge. For each subsequent transfer in a Contract year, the
Company does not currently charge but reserves the right to assess a processing
charge guaranteed never to exceed $25.
 
WHAT IF I NEED MY MONEY BEFORE MY ANNUITY PAYOUT PHASE BEGINS?
 
You may surrender the 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 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
non-natural person.) A 10% tax penalty may apply on all amounts deemed to be
income if you are under age 59 1/2. Additional amounts may be withdrawn at any
time but may be subject to the surrender charge for payments that have not been
invested in the Contract for more than seven years. (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, except where prohibited by state law, you may withdraw all or a
portion of your money without a surrender charge if, after the Contract is
issued, you are admitted to a medical care facility, become disabled or are
diagnosed with a fatal illness. For details and restrictions, see "Reduction or
Elimination of Withdrawal Charge."
 
                                       10
<PAGE>
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 an annual rate of 5%, 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 at the annual rate of 5%. 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 at the annual rate of 5%; 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, a $30 Contract fee will be deducted from the Contract. The
Contract fee is waived for Contracts issued to and maintained by a trustee of a
401(k) plan.
 
Should you decide to surrender the Contract, make withdrawals, or receive
payments under certain annuity payout options, you may be subject to a
contingent deferred sales charge. If applicable, this charge will be between 1%
and 7% of payments withdrawn, based on when the payments were made.
 
A deduction for state and local premium taxes, if any, may be made as described
under "C. Premium Taxes."
 
The Company will deduct a daily 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 for the Funds, which accompany this Prospectus.
 
CAN I EXAMINE THE CONTRACT?
 
Yes. The Contract will be delivered to you after your purchase. If you return
the Contract to the Company within ten days of receipt, the Contract will be
canceled. (There may be a longer period in certain states; see
 
                                       11
<PAGE>
the "Right to Examine" provision on the cover of the Contract.) If you cancel
the Contract, you will receive a refund of any amounts allocated to the Fixed
and Guarantee Period Accounts and the Accumulated Value of any amounts allocated
to the Sub-Accounts (plus any fees or charges that may have been deducted.) If
state law requires, or if the Contract was issued as an Individual Retirement
Annuity ("IRA") however, you will receive the greater of the amount described
above or your entire payment. See "B. Right to Revoke Individual Retirement
Annuity."
 
CAN I MAKE FUTURE CHANGES UNDER MY CONTRACT?
 
There are several changes you can make after receiving the Contract:
 
- -  You may assign your ownership to someone else, except under certain qualified
   plans.
 
- -  You may change the beneficiary, unless you have irrevocably designated a
   beneficiary.
 
- -  You may change your allocation of payments.
 
- -  You may make transfers of Contract value among your current investments
   without any tax consequences.
 
- -  You may cancel the Contract within ten days of delivery (or longer if
   required by state law).

 The Company currently makes no charge for transfers, and guarantees that the first 12

 subsequent transfer, the Company reserves the right to assess a charge, guaranteed
 never to exceed $25, to reimburse the Company for the costs of processing the
 transfer.

The following table gives certain fee and expense information for the Funds.
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

(1) A performance based advisory fee is in effect, which fee may vary anywhere
from 0.00% to 4.00%.
 
(2) Restated to reflect the expense limitation in effect during 1998. AFIMS has
agreed to limit operating expenses and reimburse those expenses to the extent
that the Portfolios' Other Expenses during 1998 (i.e., expenses other than
management fees) exceed the following expense limitations: 1.20% for the Global
Interactive/Telecomm Portfolio, 1.20% for the International Growth Portfolio,
1.00% for the Growth Portfolio, 1.00% for the Value Portfolio, and 1.20% for the
Strategic Income Portfolio. The limitations are in effect through December 31,
1998. Without the effect of the expense limitations, the 1997 "Other Expenses"
ratios would have been the following: 7.26% for the Global Interactive/Telecomm
Portfolio, 7.11% for the International Growth Portfolio, 6.12% for the Growth
Portfolio, 4.75% for the Value Portfolio, and 6.68% for the Strategic Income
Portfolio.
 
(3) The actual management fee for the Strategic Income Portfolio for 1997 was
0.41%. The fee has been restated to 0.40% because, effective April 13, 1998, a
new Portfolio Manager is in place. At a meeting of the Board of Trustees of The
Fulcrum Trust ("Board") which was held on April 9, 1998, the Board approved a
new Portfolio Manager Agreement with Allmerica Asset Management, Inc. ("AAM").
The Portfolio Manager Agreement with AAM was approved at a shareholders meeting
on June 8, 1998. The Portfolio Manager Agreement provides that during the
Portfolio Manager's first year of service, the Portfolio will pay a fixed annual
fee of 0.80% of average daily net assets, rather than paying a performance-based
fee. After the twelfth full calendar month has elapsed under the Portfolio
Manager Agreement, the performance-based fee will be in effect. Although the
Agreement sets the fee at 0.80% through April 30, 1999, the fee is subject to an
important limitation. The Manager and the Portfolio Manager have voluntarily
agreed to limit their fee from June 9, 1998 through April 30, 1999 to an annual
rate of 0.40%. See the prospectus of The Fulcrum Trust for more information.
 
(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 1997. The
limitation may be terminated at any time.
 
(5) On June 17, 1998, the Board approved a new Portfolio Manager Agreement with
Pilgrim Baxter Analytic Investors, Inc. ("Pilgrim Baxter Analytic"). The
Portfolio Manager Agreement is subject to the approval of
 
                                       14
<PAGE>
shareholders. A vote is scheduled to be held on September 15, 1998. The
Agreement provides for a fixed fee for the first year of 0.80% of average daily
net assets of the Growth Portfolio. AFIMS and Pilgrim Baxter Analytic have
agreed as well to a limitation on the first year fee. Specifically, for the
first year, the fee will be calculated at the lesser of the following two rates:
(1) 0.80%; or (2) the rate that would have applied under the old Portfolio
Manager Agreement with the previous portfolio manager. The latter rate varies
based on prior performance. After the first year of its agreement, Pilgrim
Baxter Analytic will be paid under the same performance-based fee schedule
included in the current agreement with the previous portfolio manager.
 
(6) Effective May 1, 1998 through October 31, 1998, Delaware Management Company,
the Series' investment adviser, has voluntarily agreed to waive its management
fees and reimburse Small Cap Value Series and Delaware 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, 1998. The declaration of a voluntary
expense limitation does not bind the investment adviser to declare future
expense limitations with respect to these series.
 
(7) For the fiscal year ended December 31, 1997, before waiver and/or
reimbursement by the investment adviser, Total Fund Expenses as a percentage of
average daily net assets were 0.90% for Small Cap Value Series.
 
(8) The investment adviser to MFS Growth With Income Series has voluntarily
agreed to waive expenses, such that the Series' Other Expenses shall not exceed
0.25% and Total Fund Expenses shall not exceed 1.00% of average daily net assets
of the Series during the current fiscal year. Otherwise, Other Expenses would be
0.35% and Total Fund Expenses would be 1.10%.
 
(9) Lazard Retirement International Equity Portfolio commenced operations on
September 1, 1998, therefore, expenses reflected herein are estimated and should
not be considered representative of future expenses. Actual expenses may be
greater than those shown.
 
(10) 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.
 
(11) A I M Advisors, Inc. ("AIM") may from time to time voluntarily waive or
reduce its respective fees. Effective May 1, 1998, the Fund reimburses AIM in an
amount up to 0.25% of the average net asset value of the Fund, for expenses
incurred in providing, or assuring that participating insurance companies
provide, certain administrative services. Currently, the fee only applies to the
average net asset value of the Fund in excess of the net asset value of the Fund
as calculated on April 30, 1998.

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 contingent deferred
sales charge is assessed at the time of annuitization under an option including
a life contingency or under a non-commutable period certain option of ten years
or longer.

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 Strategic Income Portfolio and 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 Portfolios' performance. The base fee of 2.00% will
be paid if the Portfolios' 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 Portfolios'
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 Portfolios' 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 1997, the actual management fees were 0.27%
for the Global Interactive/Telecomm Portfolio, 0.58% for the International
Growth Portfolio, 0.20% for the Growth Portfolio, and 0.14% for the Value
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
two Portfolios -- the Strategic Income Portfolio and the Growth Portfolio. The
Strategic Income Portfolio has retained Allmerica Asset Management, Inc. ("AAM")
as Portfolio Manager effective April 13, 1998. The Portfolio Manager Agreement
with AAM provides that, during AAM's first year of service the Portfolio will
pay a fixed annual fee of 0.80% of average daily net assets, rather than paying
a performance-based fee. After the twelfth full calendar month has elapsed under
the Portfolio Manager Agreement, the performance-based fee arrangement described
above will be in effect. However, AFIMS and AAM have voluntarily agreed that for
the first year (through April 30, 1999) the management fee will be capped at
0.40%. The fee is subject to additional limitations. The Growth Portfolio has
retained Pilgrim Baxter Analytic Investors, Inc. ("Pilgrim Baxter Analytic") as
Portfolio Manager, effective August 1, 1998. The Portfolio Manager Agreement
with Pilgrim Baxter Analytic also provides that, during Pilgrim Baxter
Analytic's first year of service, the Portfolio will pay a fixed annual fee of
0.80% of average daily net assets. AFIMS and Pilgrim Baxter Analytic have agreed
as well to a limitation on the first year fee. Specifically, for the first year,
the fee will be calculated at the lesser of the following two rates: (1) 0.80%;
or (2) the rate that would have applied under the old Portfolio Manager
Agreement with the previous portfolio manager. The latter rate varies based on
prior performance. After the first year of its agreement, Pilgrim Baxter
Analytic will be paid under the same performance-based fee schedule included in
the current agreement with the previous portfolio manager. For more information,
see Footnotes 3 and 4, below, and the prospectus for The Fulcrum Trust.

(1) A performance-based advisory fee is in effect, which fee may vary anywhere
from 0.00% to 4.00%.
 
(2) AFIMS has agreed to limit operating expenses and reimburse those expenses to
the extent that the Other Expenses of the Portfolios during 1998 (i.e., expenses
other than management fees) exceed the following expense limitations: 1.20% for
the Global Interactive/Telecomm Portfolio, 1.20% for the International Growth
Portfolio, 1.00% for the Growth Portfolio, 1.00% for the Value Portfolio, and
1.20% for the Strategic Income Portfolio. The limitations are in effect through
December 31, 1998. For the Value Portfolio and the Growth Portfolio, different
expense limitations were in effect during 1997. Without the effect of the
expense limitations, the 1997 "Other Expenses" ratios would have been 7.26% for
the Global Interactive/Telecomm Portfolio, 7.11% for the International Growth
Portfolio, 6.12% for the Growth Portfolio, 4.75% for the Value Portfolio, and
6.68% for the Strategic Income Portfolio.
 
(3) The actual management fee for the Strategic Income Portfolio for 1997 was
0.41%. The fee has been restated to 0.40% because, effective April 13, 1998, a
new Portfolio Manager is in place. At a meeting of the Board of Trustees of The
Fulcrum Trust ("Board") which was held on April 9, 1998, the Board approved a
new Portfolio Manager Agreement with Allmerica Asset Management, Inc. ("AAM").
The Portfolio Manager Agreement was approved at a shareholders meeting on June
8, 1998. The Portfolio Manager Agreement provides that during the Portfolio
Manager's first year of service, the Portfolio will pay a fixed annual fee of
0.80% of average daily net assets, rather than paying a performance-based fee.
After the twelfth full calendar month has elapsed under the Portfolio Manager
Agreement, the performance-based fee will be in effect. Although the Agreement
sets the fee at 0.80% through April 30, 1999, the fee is subject to an important
limitation. The Manager and the Portfolio Manager have voluntarily agreed to
limit their fee from June 9, 1998 through April 30, 1999 to an annual rate of
0.40%. See the prospectus of The Fulcrum Trust for more information.

(4) On June 17, 1998, the Board approved a new Portfolio Manager Agreement with
Pilgrim Baxter Analytic Investors, Inc. ("Pilgrim Baxter Analytic"). The
Portfolio Manager Agreement is subject to the approval of shareholders. A vote
is scheduled to be held on September 15, 1998. The Agreement provides for a
fixed fee for the first year of 0.80% of average daily net assets of the Growth
Portfolio. AFIMS and Pilgrim Baxter Analytic have agreed as well to a limitation
on the first year fee. For the first year, the fee will be calculated at the
lesser of the following two rates: (1) 0.80%; or (2) the rate that would have
applied under the old Portfolio Manager Agreement with the previous portfolio
manager. The latter rate varies based on prior performance. After the first year
of its agreement, Pilgrim Baxter Analytic will be paid under the same
performance-based fee schedule included in the current agreement with the
previous portfolio manager.
 
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 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 contingent deferred
sales charge is assessed at the time of annuitization under an option including
a life contingency or under a non-commutable period certain option of ten years
or longer.

                            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 the periods that the Sub-Accounts have been in existence
and 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 contingent deferred sales charge which would be
assessed if the investment were completely withdrawn at the end of the specified
period. 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
contingent deferred sales charge but 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 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
 
                                       22
<PAGE>
GIVEN TIME PERIOD, AND SHOULD NOT BE CONSIDERED AS A REPRESENTATION OF WHAT MAY
BE ACHIEVED IN THE FUTURE.
 
Performance information for a Sub-Account may be compared, in reports and
promotional literature, to: (1) the Standard & Poor's 500 Composite Stock Price
Index ("S&P 500"), Dow Jones Industrial Average ("DJIA"), Shearson Lehman
Aggregate Bond Index or other unmanaged indices so that investors may compare
the Sub-Account results with those of a group of unmanaged securities widely
regarded by investors as representative of the securities markets in general;
(2) other groups of variable annuity separate accounts or other investment
products tracked by Lipper Analytical Services, a widely used independent
research firm which ranks mutual funds and other investment products by overall
performance, investment objectives, and assets, or tracked by other services,
companies, publications, or persons, who rank such investment products on
overall performance or other criteria; or (3) the Consumer Price Index (a
measure for inflation) to assess the real rate of return from an investment in
the Sub-Account. Unmanaged indices may assume the reinvestment of dividends but
generally do not reflect deductions for administrative and management costs and
expenses.
 
At times, the Company may also advertise the ratings and other information
assigned to it by independent rating organizations such as A.M. Best Company
("A.M. Best"), Moody's Investors Service ("Moody's"), Standard & Poor's
Insurance Rating Services ("S&P") and Duff & Phelps. A.M. Best's and Moody's
ratings reflect their current opinion of the Company's relative financial
strength and operating performance in comparison to the norms of the life/health
insurance industry. S&P's and Duff & Phelps' ratings measure the ability of an
insurance company to meet its obligations under insurance policies it issues and
do not measure the ability of such companies to meet other non-policy
obligations. The ratings also do not relate to the performance of the Funds.
 
                DESCRIPTION OF THE COMPANY, THE VARIABLE ACCOUNT
                            AND THE UNDERLYING FUNDS
 
THE COMPANY
 
The Company is a life insurance company organized under the laws of Delaware in
July 1974. Its principal office ("Principal Office") is located at 440 Lincoln

jurisdictions in which it is licensed to operate. As of December 31, 1997, the
Company had over $9.4 billion in assets and over $26.6 billion of life insurance
in force.
 
Effective October 1, 1995, the Company changed its name from SMA Life Assurance
Company to Allmerica Financial Life Insurance and Annuity Company. The Company
is an indirect wholly owned subsidiary of First Allmerica Financial Life

THE VARIABLE ACCOUNT
 
The Fulcrum Separate Account (the "Variable Account") is a separate investment
account of the Company with fourteen 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 law, the assets of the Variable Account
may not be charged with any liabilities arising out of any other business of the
Company.
 
The Variable Account was authorized by vote of the Board of Directors of the
Company on June 13, 1996. The Variable Account meets the definition of "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 of management or investment practices or policies of the Variable
Account by the SEC.
 
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 (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:

Strategic Income Portfolio                 Allmerica Asset Management, Inc.
</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 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 two Portfolios
- -- the Strategic Income Portfolio and the Growth Portfolio. The Strategic Income
Portfolio has a new Portfolio Manager, AAM, effective April 13, 1998. The
Portfolio Manager Agreement with AAM was approved at a shareholders meeting on
June 8, 1998. AFIMS and AAM have voluntarily agreed that for the first year
(through April 30, 1999) the management fee for the Strategic Income Portfolio
will be set at 0.40%. The Growth Portfolio also has a new Portfolio Manager,
Pilgrim Baxter Analytic Investors, Inc. ("Pilgrim Baxter Analytic"), effective
August 1, 1998. The Portfolio Manager Agreement with Pilgim Baxter Analytic is
subject to the approval of shareholders. A vote is scheduled to be held on
September 15, 1998. The agreement provides for a fixed fee for the first year
equal to 0.80% of average daily net assets of the Growth Portfolio. AFIMS and
Pilgrim Baxter Analytic have agreed as well to a limitation on the first year
fee. Specifically, for the first year, the fee will be calculated at the lesser
of the following two rates: (1) 0.80%; or (2) the rate that would have applied
under the old Portfolio Manager
 
                                       24
<PAGE>
Agreement with the previous portfolio manager. The latter rate varies based on
prior performance. After the first year of its agreement, Pilgrim Baxter
Analytic will be paid under the same performance-based fee schedule included in
the current agreement with the previous portfolio manager.
 
Other than the Strategic Income Portfolio and 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 a 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.

assets of various variable accounts established by the Company or other
affiliated 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. The terms of the Sub-Adviser
Agreement cannot be materially changed without the approval of a majority in
interest of the shareholders of the Fund. 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.

If there is a material change in the investment policy of a Fund, the Owner will
be notified of the change. If the Owner has Accumulated Value allocated to that
Fund, he or she may have the Accumulated Value reallocated 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's underwriting requirements, which include receipt of the initial
payment and allocation instructions by the Company at its Principal Office, must
be met before a contract can be issued. These requirements also may include the
proper completion of an application; however, where permitted, the Company may
issue a contract without completion of an application 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 will be credited to the Contract as of the date that all
issue requirements are properly met. If all issue requirements are not complied
with within five business days of the Company's receipt of the initial payment,
the payment will be returned unless the Owner specifically consents to the
holding of the initial payment until completion of any outstanding issue
requirements. Subsequent payments will be credited as of the Valuation Date
received at the Principal Office.
 
                                       27
<PAGE>
Payments are not limited as to frequency and number, but there are certain
limitations as to amount. Currently, the initial payment must be at least
$25,000. 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.
To the extent permitted by state law, however, if the Contract is issued as an
IRA or is issued in Georgia, Idaho, Indiana, Michigan, Missouri, North Carolina,
Oklahoma, Oregon, South Carolina, Texas, Utah, Washington or West Virginia, any
portion of the initial net payment and of additional net payments received
during the Contract's first 15 days measured from the issue date, allocated to
any Sub-Account and/or any Guarantee Period Account, will be held in the Money
Market Fund until the end of the 15-day period. Thereafter, these amounts will
be allocated as requested.
 
The Owner may change allocation instructions for new payments pursuant to a
written or telephone request. If telephone requests are elected by the Owner, a
properly completed authorization must be on file before telephone requests will
be honored. The policy of the Company and its agents and affiliates is that they
will not be responsible for losses resulting from acting upon telephone requests
reasonably believed to be genuine. The Company will employ reasonable procedures
to confirm that instructions communicated by telephone are genuine; otherwise,
the Company may be liable for any losses due to unauthorized or fraudulent
instructions. The procedures the Company follows for transactions initiated by
telephone include requirements that callers on behalf of the Owner identify
themselves by name and identify the Annuitant by name, date of birth and social
security number. All transfer instructions by telephone are tape recorded.
 
B.  RIGHT TO REVOKE INDIVIDUAL RETIREMENT ANNUITY
 
An individual purchasing a Contract intended to qualify as an Individual
Retirement Annuity ("IRA") may revoke the Contract at any time within ten days
after receipt of the Contract and receive a refund. In order to revoke 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
revocation to be effective.
 
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 Underlying 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 REVOKE ALL OTHER CONTRACTS
 
In Georgia, Idaho, Indiana, Michigan, Missouri, North Carolina, Oklahoma,
Oregon, South Carolina, Texas, Utah, Washington and West Virginia, an Owner may
revoke the Contract at any time within ten days (20 in Idaho) after receipt of
the Contract and receive a refund as described under "B. Right to Revoke
Individual Retirement Annuity," above.
 
In all other states, an Owner may return the Contract at any time within ten
days (or the number of days required by state law if more than ten) after
receipt of the contract. The Company will pay to the Owner an
 
                                       28
<PAGE>
amount equal to the sum of (1) the difference between the premium paid,
including fees, and any amount allocated to the Variable Account; and (2) the
Accumulated Value of amounts allocated to the Variable Account as of the date
the request is received. If the contract was purchased as an IRA, the IRA
revocation right described above may be utilized in lieu of the special
surrender right.
 
D.  TRANSFER PRIVILEGE
 
At any time prior to the Annuity Date the Owner may have amounts transferred
among all accounts. Transfer values will be effected at the Accumulation Value
next computed after receipt of the transfer order. The Company will make
transfers pursuant to written or telephone requests. As discussed in "A.
Payments," a properly completed authorization form must be on file before
telephone requests will be honored. 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.
 
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 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 transfers. For more information see APPENDIX A, "MORE INFORMATION
ABOUT THE FIXED ACCOUNT."
 
The Owner may request automatic rebalancing of Sub-Account allocations on a
monthly, bi-monthly, quarterly, semi-annual or annual basis in accordance with
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. Currently, Dollar Cost Averaging and Automatic Account
Rebalancing may not be in effect simultaneously. Either option may be elected
when the Contract is purchased or at a later date.
 
                                       29
<PAGE>
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 amount payable to the Owner upon surrender will be based
on the Contract's Accumulated Value as of the Valuation Date on which the
request and the Contract are received at the Principal Office.
 
Before the Annuity Date, a contingent deferred sales 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, the Contract may be surrendered only if a commutable
period certain option has been elected. The Surrender Value is the commuted
value of any unpaid installments, computed on the basis of the assumed interest
rate incorporated in such annuity benefit payments. No contingent deferred sales
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.
 
The right is reserved by the Company 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 file a signed, written request for withdrawals, satisfactory to
the Company, at 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 contingent deferred sales 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. No withdrawals 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."
 
                                       30
<PAGE>
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 account. The first
withdrawal will take place on the date the written request is received at the
Principal Office or, if later, on a date specified by the Owner.
 
If a withdrawal would cause the remaining Accumulated Value to be less than
$1,000, systematic withdrawals will be discontinued. Systematic withdrawals will
cease automatically on the Annuity Date. The Owner may change or terminate
systematic withdrawals only by written request to the Principal Office.
 
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 a life expectancy distribution ("LED") option by returning
a properly signed LED request form to the Principal Office. The LED option
permits the Owner to make systematic withdrawals from the Contract over his or
her lifetime. The amount withdrawn from the Contract changes each year, because
life expectancy changes each year that a person lives. For example, actuarial
tables indicate that a person age 70 has a life expectancy of 16 years, but a
person who attains age 86 has a life expectancy of another 6.5 years.
 
Where the Owner is a trust or other non-natural person, the Owner may elect the
LED option based on the Annuitant's life expectancy.
 
If an Owner elects the LED option, in each calendar year a fraction of the
Accumulated Value is withdrawn based on the Owner's then life expectancy. The
numerator of the fraction is 1 (one), and the denominator of the fraction is the
remaining life expectancy of the Owner, as determined annually by the Company.
The resulting fraction, expressed as a percentage, is applied to the Accumulated
Value at the beginning of the year to determine the amount to be distributed
during the year. The Owner may elect monthly, bi-monthly, quarterly,
semi-annual, or annual distributions, and may terminate the LED option at any
time. The Owner also may elect to receive distributions under a LED option which
is determined on the joint life expectancy of the Owner and a beneficiary. The
Company also may offer other systematic withdrawal options.
 
If an Owner makes withdrawals under the LED option prior to age 59 1/2, the
withdrawals may be treated by the Internal Revenue Service ("IRS") as premature
distributions from the Contract. The payments then would be taxed on an "income
first" basis and be subject to a 10% federal tax penalty. For more information,
see "FEDERAL TAX CONSIDERATIONS," "B. Taxation of the Contracts in General."

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 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 for any
positive Market Value Adjustment; (2) gross payments, compounded daily at an
annual rate of 5% starting on the date each payment is applied, decreased
proportionately to reflect withdrawals (for each withdrawal, the proportionate
reduction is calculated as the death benefit under this option immediately prior
to the withdrawal multiplied by the withdrawal amount and divided by the
Accumulated Value immediately prior to the withdrawal); 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 at the annual rate of 5%. 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 at the annual rate of 5%; 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.
 
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 will
generally 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.
 
                                       32
<PAGE>
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 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. All other rights and benefits provided in the Contract
will continue, except that any subsequent spouse of such new Owner will not be
entitled to continue the Contract upon such new Owner's death.
 
I.  ASSIGNMENT
 
The Contract, other than those sold in connection with certain qualified plans,
may be assigned by the Owner at any time prior to the Annuity Date and 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 Annuity Date is selected by the Owner. To the extent permitted in the
Owner's state, 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. 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 option 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
 
                                       33
<PAGE>
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 option selected does not produce an
initial payment which meets this minimum, a single payment will be made. Once
the Company begins making annuity benefit payments, the Annuitant cannot make
withdrawals 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 otherwise, a variable life annuity with periodic
payments for ten years guaranteed will be purchased. Changes in either the
Annuity Date or annuity option can be made up to one month prior to the Annuity
Date.
 
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.
 
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.  It would be possible under this option for the Annuitant to receive only
one annuity benefit payment if the Annuitant dies prior to the due date of the
second annuity benefit payment, two annuity benefit payments if the Annuitant
dies before the due date of the third annuity benefit payment, and so on.
Payments, however, will continue during the lifetime of the Annuitant, 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 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 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.
 
                                       34
<PAGE>
PERIOD CERTAIN VARIABLE ANNUITY.  This variable annuity has periodic payments
for a stipulated number of years ranging from one to 30. This option may be
commutable, that is, the payee reserves the right to receive a lump sum in place
of installments, or it becomes non-commutable. The payee must reserve this right
at the time benefits begin.
 
It should be noted that the period certain option does not involve a life
contingency. In the computation of the payments under this option, the Company
charges for annuity rate guarantees, which guarantees include 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
 
THE ANNUITY UNIT.  On and after the Annuity Date, the Annuity Unit is a measure
of the value of the Annuitant's 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 product of (1) the net
investment factor of the Sub-Account for the current Valuation Period and (2) a
factor to adjust benefits to neutralize the assumed interest rate. The assumed
interest rate, discussed below, is incorporated in the variable annuity options
offered in the Contract.
 
DETERMINATION OF THE FIRST AND SUBSEQUENT ANNUITY BENEFIT PAYMENTS.  The first
periodic annuity benefit payment is based upon the Accumulated Value as of a
date not more than four weeks preceding the date that the first annuity benefit
payment is due. Variable annuity benefit payments are due on the first of a
month, which is the date the payment is to be received by the Annuitant, and
currently are based on unit values as of the 15th day of the preceding month.
 
The Contract provides annuity rates which determine the dollar amount of the
first periodic payment under each form of annuity for each $1,000 of applied
value. For life option and non-commutable period certain options of ten or more
years, the annuity value is the Accumulated Value less any premium taxes and
adjusted for any Market Value Adjustment. For commutable period certain options
or any period certain option less than ten years, the value is the Surrender
Value less any premium tax. For a death benefit annuity, the annuity value will
be the amount of the death benefit. The annuity rates in the Contract are based
on a modification of the 1983(a) Individual Mortality Table on rates.
 
The amount of the first monthly payment depends upon the form of annuity
selected, the sex (however, see "M. NORRIS Decision") and age of the Annuitant
and the value of the amount applied under the annuity option. The variable
annuity options offered by the Company are based on a 3 1/2% assumed interest
rate. Variable payments are affected by the assumed interest rate used in
calculating the annuity option rates. Variable annuity benefit payments will
increase over periods when the actual net investment result of the Sub-Accounts
funding the annuity exceeds the equivalent of the assumed interest rate for the
period. Variable annuity benefit payments will decrease over periods when the
actual net investment result of the respective Sub-Account is less than the
equivalent of the assumed interest rate for the period.
 
The dollar amount of the first periodic annuity benefit payment under life
annuity options and non-commutable period certain options of ten years or more
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, the Surrender Value less premium taxes, if any,
is used rather than the Accumulated Value. The dollar amount of the first
variable annuity benefit payment is then divided by the value of an Annuity Unit
of the selected Sub-Accounts to
 
                                       35
<PAGE>
determine the number of Annuity Units represented by the first payment. This
number of Annuity Units remains fixed under all annuity options except the joint
and two-thirds survivor annuity option. For each subsequent payment, the dollar
amount of the variable annuity benefit payment is determined by multiplying this
fixed number of Annuity Units by the value of an Annuity Unit on the applicable
Valuation Date.
 
After the first benefit payment, the dollar amount of each periodic variable
annuity benefit payment will vary with subsequent variations in the value of the
Annuity Unit of the selected Sub-Accounts. The dollar amount of each fixed
amount annuity benefit payment is fixed and will not change, except under the
joint and two-thirds survivor annuity option.
 
From time to time, the Company may offer Owners both fixed and variable annuity
rates more favorable than those contained in the Contract. Any such rates will
be applied uniformly to all Owners of the same class.
 
For an illustration of a variable annuity benefit payment calculation using a
hypothetical example, see "ANNUITY BENEFIT PAYMENTS" in the SAI.
 
M.  NORRIS DECISION
 
In the case of ARIZONA GOVERNING COMMITTEE V. NORRIS, the United States Supreme
Court ruled that, in connection with retirement benefit options offered under
certain employer-sponsored employee benefit plans, annuity options based on
sex-distinct actuarial tables are not permissible under Title VII of the Civil
Rights Act of 1964. The ruling requires that benefits derived from contributions
paid into a plan after August 1, 1983 be calculated without regard to the sex of
the employee. Annuity benefits attributable to payments received by the Company
under a Contract issued in connection with an employer-sponsored benefit plan
affected by the NORRIS decision will be based on the greater of (1) the
Company's unisex Non-Guaranteed Current Annuity Option Rates or (2) the
guaranteed unisex rates described in such Contract, regardless of whether the
Annuitant is male or female.
 
N.  COMPUTATION OF VALUES
 
THE ACCUMULATION UNIT.  Each net payment is allocated to the accounts selected
by the Owner. Allocations to the Sub-Accounts are credited to the Contract in
the form of Accumulation Units. Accumulation Units are credited separately for
each Sub-Account. The number of Accumulation Units of each Sub-Account credited
to the Contract is equal to the portion of the net payment allocated to the
Sub-Account, divided by the dollar value of the applicable Accumulation Unit as
of the Valuation Date the payment is received at the Principal Office. The
number of Accumulation Units resulting from each payment will remain fixed
unless changed by a subsequent split of Accumulation Unit value, a transfer, a
withdrawal, or surrender. The dollar value of an Accumulation Unit of each
Sub-Account varies from Valuation Date to Valuation Date based on the investment
experience of that Sub-Account and will reflect the investment performance,
expenses and charges of its 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 B, "SURRENDER CHARGES AND THE MARKET VALUE
ADJUSTMENT."
 
The Accumulated Value under the Contract is determined by (1) multiplying the
number of Accumulation Units in each Sub-Account by the value of an Accumulation
Unit of that Sub-Account on the Valuation Date, (2) adding the products, and (3)
adding the amount of the accumulations in the Fixed Account and Guarantee Period
Accounts, if any.
 
NET INVESTMENT FACTOR.  The Net Investment Factor is an index that measures the
investment performance of a Sub-Account from one Valuation Period to the next.
This factor is equal to 1.000000 plus the result from dividing (1) by (2) and
subtracting (3) and (4) where:
 
                                       36
<PAGE>
    (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 Fulcrum, the Trust, AVIF,
DGPF, Lazard, the MFS Trust and Oppenheimer.
 
A.  VARIABLE ACCOUNT DEDUCTIONS
 
MORTALITY AND EXPENSE RISK CHARGE.  The Company makes a daily charge equal to an
annual rate of 1.25% of the value of each Sub-Account's assets to cover the
mortality and expense risk which the Company assumes in relation to the variable
portion of the Contract. The charge is imposed during both the accumulation
period and the annuity payout period. The mortality risk arises from the
Company's guarantee that it will make annuity benefit payments in accordance
with annuity rate provisions established at the time the Contract is issued for
the life of the Annuitant (or in accordance with the annuity option selected),
no matter how long the Annuitant (or other payee) lives and no matter how long
all Annuitants as a class live. Therefore, the mortality charge is deducted
during the annuity phase on all contracts, including those that do not involve a
life contingency, even though the Company does not bear direct mortality risk
with respect to variable annuity settlement options that do not involve life
contingencies. The expense risk arises from the Company's guarantee that the
charges it makes will not exceed the limits described in the Contract and in
this Prospectus.
 
If the charge for mortality and expense risks is not sufficient to cover actual
mortality experience and expenses, the Company will absorb the losses. If
expenses are less than the amounts provided to the Company by the charge, the
difference will be a profit to the Company. To the extent this charge results in
a profit to the Company, such profit will be available for use by the Company
for, among other things, the payment of distribution, sales and other expenses.
 
Since mortality and expense risks involve future contingencies which are not
subject to precise determination in advance, it is not feasible to identify
specifically the portion of the charge which is applicable to each. The Company
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 period and the
annuity period. 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.
 
                                       37
<PAGE>
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 includes, 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 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 Fulcrum,
the Trust, AVIF, DGPF, Lazard, the MFS Trust and Oppenheimer 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
classes of individuals ("eligible persons"): employees and registered
representatives of any broker dealer which has entered into a sales agreement
with the Company to sell the Contract; employees of the Company, its affiliates
and subsidiaries; officers, directors, trustees and employees of any of the
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.  PREMIUM TAXES
 
Some states and municipalities impose a premium tax on variable annuity
contracts. State premium taxes currently range up to 3.5%.
 
The Company makes a charge for state and municipal premium taxes, when
applicable, and deducts the amount paid as a premium tax charge. The current
practice of the Company is to deduct the premium tax charge in one of two ways:
 
    (1) if the premium tax was paid by the Company when payments were received,
       the premium tax charge is deducted on a pro-rata basis when withdrawals
       are made, upon surrender of the Contract, or when annuity benefit
       payments begin (the Company reserves the right instead to deduct the
       premium tax charge for these contracts at the time the payments are
       received); or
 
    (2) the premium tax charge is deducted when annuity benefit payments begin.
 
In no event will a deduction be taken before the Company has incurred a tax
liability under applicable state law.
 
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.
 
                                       38
<PAGE>
D.  CONTINGENT DEFERRED SALES CHARGE
 
No charge for sales expense is deducted from payments at the time the payments
are made. A contingent deferred sales 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 contingent deferred sales 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 not defined as New Payments;
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 contingent deferred sales charge, 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 contingent deferred sales charge. If a withdrawal is
attributable all or in part to New Payments, a contingent deferred sales charge
may apply.
 
CHARGE FOR SURRENDER AND WITHDRAWALS.  If the Contract is surrendered, or if New
Payments are withdrawn, while the Contract is in force and before the Annuity
Date, a contingent deferred sales charge may be imposed. The amount of the
charge will depend upon the number of years that the New Payments, if any, 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 earliest New Payment and then from the
next earliest 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 Contingent Deferred Sales Charges are as follows:

The amount withdrawn equals the amount requested by the Owner plus the charge,
if any. The charge is applied as a percentage of the New Payments withdrawn, but
in no event will the total contingent deferred sales charge exceed a maximum
limit of 7.0% of total gross New Payments. Such total charge equals the
aggregate of all applicable contingent deferred sales charges for surrender,
withdrawals, and annuitization.
 
REDUCTION OR ELIMINATION OF WITHDRAWAL CHARGE.  Where permitted by state law,
the Company will waive the contingent deferred sales charge in the event that an
Owner (or the Annuitant, if the Owner is not an individual): (1) is admitted to
a medical care facility after the issue date of the Contract and remains
confined there until the later of one year after the issue date or 90
consecutive days; (2) is first diagnosed by a licensed physician as having a
fatal illness after the issue date of the Contract; (3) is physically disabled
after the issue date of the Contract and before attaining age 65; or (4)
commencing one year after issue of the Contract, is confined to a hospice or
receives home health services, with certification from a licensed physician that
the confinement to the hospice or receipt of home health care services is
expected to continue until death. The
 
                                       39
<PAGE>
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.
 
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.
 
Where contingent deferred sales charges have been waived under any one of the
four situations discussed above, no additional payments under the Contract will
be accepted.
 
In addition, where permitted by law, the Company may reduce or waive contingent
deferred sales charges and/ or credit additional amounts on Contracts issued
where either the Owner or the Annuitant on the issue date is within the
following classes of individuals ("eligible persons"): employees and registered
representatives of any broker-dealer which has entered into a Sales Agreement
with the Company to sell the Contract; employees of the Company, its
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
contingent deferred sales, 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, contingent
deferred sales 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 contingent deferred sales 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 contingent
deferred sales 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 contingent deferred sales 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
                  contingent deferred sales charge was applied.
 
                                       40
<PAGE>
Where:  (3)  is:  The amount calculated under the Company's life expectancy
                  distribution (see "Life Expectancy Distributions") 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
 
    (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 contingent deferred sales load, 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 contingent deferred sales 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 contingent deferred sales 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 contingent deferred sales 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 THE CONTRACT," and see "FEDERAL TAX
CONSIDERATIONS."
 
CHARGE AT THE TIME ANNUITY BENEFIT PAYMENTS BEGIN.  If any commutable period
certain option or a non-commutable period certain option for less than ten years
is chosen, a contingent deferred sales charge will be deducted from the
Accumulated Value of the Contract if the Annuity Date occurs at any time when
the surrender charge would still apply had the Contract been surrendered on the
Annuity Date.
 
No contingent deferred sales charge is imposed at the time of annuitization in
any Contract year under an option involving a life contingency or for any
non-commutable period certain option for ten years or more. 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 contingent deferred
sales charge applicable under the fixed contract if a period certain option is
chosen, will be applied towards the variable
 
                                       41
<PAGE>
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.
 
E.  TRANSFER CHARGE
 
The Company currently makes no charge for processing transfers. The Company
guarantees that the first 12 transfers in a Contract year will be free of
transfer charge, but reserves the right to assess a charge, guaranteed never to
exceed $25, for each subsequent transfer in a Contract year. For more
information, see "D. Transfer Privilege."
 
                           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. 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; however,
once an interest rate is in effect for a Guarantee Period Account, 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
 
                                       42
<PAGE>
of the Guarantee Period Account without application of a Market Value
Adjustment. This practice may be discontinued or changed at the Company's
discretion.
 
MARKET VALUE ADJUSTMENT.  No Market Value Adjustment will be applied to
transfers, withdrawals, or a surrender from a Guarantee Period Account on the
expiration of its Guarantee Period. In addition, no negative Market Value
Adjustment will be applied to a death benefit although a positive Market Value
Adjustment, if any, will be applied to increase the value of the death benefit
when based on the Contract's Accumulated Value. See "G. Death Benefit." All
other transfers, withdrawals, or a surrender prior to the end of a Guarantee
Period will be subject to a Market Value Adjustment, which may increase or
decrease the account value. 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, in order
to ensure that on the last day of the Guarantee Period it will equal the amount
of the entire initial payment. The required amount then will be allocated to the
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
 
                                       43
<PAGE>
Guarantee Period Account for up to six months from the date it receives the
withdrawal request. If deferred for 30 days or more, the Company will pay
interest on the amount deferred at a rate of at least 3%.
 
In the event that a Market Value Adjustment applies to a withdrawal of a portion
of the value of a Guarantee Period Account, it will be calculated on the amount
requested and deducted or added to the amount remaining in the Guarantee Period
Account. If the entire amount in a Guarantee Period Account is requested, the
adjustment will be made to the amount payable. If a contingent deferred sales
charge applies to the withdrawal, it will be calculated as set forth under "D.
Contingent Deferred Sales 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 provide that the investments of a segregated asset
account underlying a variable annuity contract are diversified adequately 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. If the investments
are not adequately diversified, the income on a 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 Underlying Funds 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.
 
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
 
                                       44
<PAGE>
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 "Non-Natural Owners" below), be considered an annuity
contract under Section 72 of the Code. 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 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 the LED option prior to age 59 1/2. Subsequent Private Letter Rulings,
however, have treated LED-type withdrawal programs as effectively avoiding the
10% penalty tax. The position of the IRS on this issue is unclear.
 
                                       45
<PAGE>
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.
 
NON-NATURAL OWNERS.  As a general rule, deferred annuity contracts owned by
"non-natural persons" (e.g., a corporation) are not treated as annuity contracts
for federal tax purposes, and the investment income attributable to
contributions made after February 28, 1986 is taxed as ordinary income that is
received or accrued by the owner during the taxable year. This rule does not
apply to annuity contracts purchased with a single payment when the annuity date
is no later than a year from the issue date or to deferred annuities owned by
qualified employer plans, estates, employers with respect to a terminated
pension plan, and entities other than employers, such as a trust, holding an
annuity as an agent for a natural person. This exception, however, will not
apply in cases of any employer who is the owner of an annuity contract under a
non-qualified deferred compensation plan.
 
DEFERRED COMPENSATION PLANS OF STATE AND LOCAL GOVERNMENTS AND TAX-EXEMPT
ORGANIZATIONS. Under Section 457 of the Code, deferred compensation plans
established by governmental and certain other tax-exempt employers for their
employees may invest in annuity contracts. Contributions and investment earnings
are not taxable to employees until distributed. 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.
 
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
 
                                       46
<PAGE>
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 revoke the Contract as described
in this Prospectus. See "B. Right to Revoke Individual Retirement Annuity."
 
Eligible employers that meet specified criteria may establish simplified
employee pension plans (SEP-IRAs) or SIMPLE IRA plans for their employees using
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 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.
 
                                    REPORTS
 
The Owner is sent a report semi-annually which states certain financial
information about the Funds. The Company also will furnish an annual report to
the Owner containing a statement of his or her account, including unit values
and other information as required by applicable law, rules and regulations.
Loans are available to Owners of TSA Contracts (i.e., Contracts issued under
Section 403(b) of the Code and to Contracts issued to plans qualified under
Sections 401(a) and 401(k) of the Code. Loans are subject to provisions of the
Code and to applicable qualified retirement plan rules. Tax advisors and plan
fiduciaries should be consulted prior to exercising loan privileges.
 
                                       47
<PAGE>
                        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, 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 Fulcrum, the Trust, AVIF, DGPF, Lazard, the MFS Trust and
Oppenheimer 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
 
                                       48
<PAGE>
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.
 
                                 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.
 
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

                                   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 contingent deferred sales 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.
 
An eligible payment must be automatically transferred out of the Fixed Account
over a continuous six month period. The enhanced rate will apply during the six
month period to any portion of the eligible payment remaining in the Fixed
Account. Amounts automatically transferred out of the Fixed Account will no
longer earn the enhanced rate of interest and, as of the date of transfer, will
be subject to the variable investment performance of the sub-account(s)
transferred into. If the automatic transfer option is terminated prior to the
end of the six month period, the enhanced rate will no longer apply. The Company
reserves the right to extend the period of time that the enhanced rate will
apply.

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
    Guaranteed Interest Rate of 8%.
 
2.  The date of surrender is seven years (2,555 days) from the expiration date.
 
3.  The value of the Guarantee Period Account is equal to $62,985.60 at the end
    of three years.
 
                                      B-1
<PAGE>
4.  No transfers or withdrawals affecting this Guarantee Period Account have
    been made.
 
5.  Surrender charges, if any, are calculated in the same manner as shown in the
    examples in Part 1.

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 6.0% 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. 

The aggregate amounts of commissions paid to Western Capital Financial Group, 
Inc. and to independent broker-dealers, respectively, for sales of contracts 
funded by Fulcrum Separate Account were $529,272.25 and $588,878.81 in 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:

(1)  Accumulation Unit Value -- Previous Valuation Period. . . . $ 1.135000

(2)  Value of Assets -- Beginning of Valuation Period. . . . . . $5,000,000

(3)  Excess of Investment Income and Net Gains Over Capital Losses . $1,675


                                       4
<PAGE>

(4)  Adjusted Gross Investment Rate for the Valuation 
     Period (3) divided by (2) . . . . . . . . . . . . . . . . . . 0.000335

(5)  Annual Charge (one-day equivalent of 1.45% per annum) . . . . 0.000040

(6)  Net Investment Rate (4) - (5) . . . . . . . . . . . . . . . . 0.000295

(7)  Net Investment Factor 1.000000 + (6). . . . . . . . . . . . . 1.000295

(8)  Accumulation Unit Value -- Current Period (1) x (7) . . . . $ 1.135335

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 contingent deferred sales 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.

CONTINGENT DEFERRED SALES CHARGE COMPUTATION.  No surrender charge otherwise 
applicable to the Exchanged Contract will be assessed as a result of the 
exchange.  Instead, the contingent deferred sales 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 contingent deferred sales 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.

CONTINGENT DEFERRED SALES CHARGE.  The contingent deferred sales 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 contingent deferred sales 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 contingent deferred sales 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 revoke the new Contract within the time 
permitted, as described in the sections of this   Prospectus captioned "Right 
to Revoke Individual Retirement Annuity" and "Right to Revoke All Other 
Contracts," will have their exchanged contract automatically reinstated as of 
the date of revocation.  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 contingent deferred sales 
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 contingent 
deferred sales 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 contingent 
deferred sales 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.

</TABLE>

            * Subject to the maximum limit described in the Prospectus.

No contingent deferred sales 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 contingent 
deferred sales 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 contingent 
deferred sales charge and assume that the Contract is not surrendered at the 
end of the periods shown. See Table 2A.

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, 1997:

     Yield               4.30%
     Effective Yield     4.39%

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, 
subtracting a charge reflecting the annual 1.45%  deduction for mortality and 
expense risk and the administrative charge, 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 annual 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 deferred sales 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.

                         NOTES TO FINANCIAL STATEMENTS
 
1.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
A.  BASIS OF PRESENTATION AND PRINCIPLES OF CONSOLIDATION
 
Allmerica Financial Life Insurance and Annuity Company ("AFLIAC" or the
"Company") is organized as a stock life insurance company, and is a wholly-owned
subsidiary of SMA Financial Corporation ("SMAFCO"), which is wholly owned by
First Allmerica Financial Life Insurance Company ("FAFLIC"). FAFLIC is a
wholly-owned subsidiary of Allmerica Financial Corporation ("AFC").
 
The consolidated financial statements of AFLIAC include the accounts of Somerset
Square, Inc., a wholly-owned non-insurance company and its results of operations
for the month of December, 1997. Somerset Square, Inc. was transferred from
SMAFCO effective November 30, 1997. (See Significant Transactions.)
 
The Statutory stockholder's equity of the Company is being maintained at a
minimum level of 5% of general account assets by FAFLIC in accordance with a
policy established by vote of FAFLIC's Board of Directors.
 
The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and
the reported amount of revenues and expenses during the reporting period. Actual
results could differ from those estimates. Certain reclassifications have been
made to the 1996 financial statements in order to conform to the 1997
presentation.
 
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 reevaluates such designation as of each balance sheet date.
 
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 management 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 management believes may not be collectible in
full. In establishing reserves, management 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 committed to a plan to dispose of all real estate
assets by the end of 1998. As a result of this decision real estate held by the
Company and real estate joint ventures were written down to the estimated fair
value less cost to sell. Depreciation is not recorded on these assets while they
are held for disposal.
 
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
 
                                      F-5

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)
 
or a group of investments is determined, a realized investment loss is recorded.
Changes in the valuation allowance for mortgage loans and real estate 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, management 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, health 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 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 2 1/2% to 6% for
life insurance and 2% to 9 1/2% for
 
                                      F-6
<PAGE>
                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)
 
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 health
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. These liabilities are determined using case basis
evaluations and statistical analyses and represent estimates of the ultimate
cost of all claims incurred but not paid. These estimates are continually
reviewed and adjusted as necessary; such adjustments are reflected in current
operations.
 
Premiums for individual accident and health insurance are reported as earned on
a pro-rata basis over the contract period.
 
The unexpired portion of these premiums is recorded as unearned premiums.
 
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, management
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 health insurance and individual annuity
products, excluding universal life and investment-related products, are
considered revenue when due. Individual accident and health insurance premiums
are recognized as revenue over the related contract periods. 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, and mortality, administration and surrender charges
assessed against the fund values. Related benefit expenses include universal
life benefits 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, its life insurance subsidiaries, FAFLIC and AFLIAC, and its non-life
insurance domestic subsidiaries file a life-nonlife 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 insurance company taxable
operating losses that can be applied to offset life insurance company taxable
income. Allmerica P&C and its subsidiaries will be included in the AFC
consolidated return as part of the
 
                                      F-7
<PAGE>
                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)
 
non-life insurance company subgroup for the period July 17, 1997 through
December 31, 1997. For the period January 1, 1997 through July 16, 1997,
Allmerica P&C and its subsidiaries will file a separate consolidated United
States Federal income tax return.
 
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 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" (SFAS No.
109). These differences result primarily from loss reserves, policy acquisition
expenses, and unrealized appreciation/depreciation on investments.
 
J.  NEW ACCOUNTING PRONOUNCEMENTS
 
In June 1997, the FASB issued Statement No. 131, DISCLOSURES ABOUT SEGMENTS OF
AN ENTERPRISE AND RELATED INFORMATION. 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 beginning
after December 15, 1997. The Company anticipates no impact from the adoption of
Statement No. 131.
 
In June 1997, the FASB also issued Statement No. 130, REPORTING COMPREHENSIVE
INCOME, 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
anticipates that the adoption of Statement No. 130 will result primarily in
reporting the changes in unrealized gains and losses on investments in debt and
equity securities in comprehensive income.
 
2.  SIGNIFICANT TRANSACTIONS
 
On April 14, 1997, the Company entered into an agreement in principle to
transfer the Company's individual disability income under a 100% coinsurance
agreement to Metropolitan Life Insurance Company. 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 the 4th quarter of 1997, SMAFCO contributed $40.6 million of additional
paid in capital to the Company. The nature of the contribution was $19.2 million
in cash and $21.4 million in other assets including Somerset Square, Inc.

Effective January 1, 1998, the Company entered into an agreement with
Reinsurance Group of America, Inc. to reinsure the mortality risk on the
universal life and variable universal life blocks of business. Management
believes that this agreement will not have a material effect on the results of
operations or financial position of the Company.

(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, 1997, the amortized
cost and market value of these assets on deposit were $276.8 million and $291.7
million, respectively. At December 31, 1996, the amortized cost and market value
of these assets on deposit were $284.9 million and $292.2 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, 1997 and 1996.
 
There were no contractual fixed maturity investment commitments at December 31,
1997 and 1996, 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 $9.4 million and $9.5 million at December 31,
1997 and 1996, respectively.
 
During 1997, the Company committed to a plan to dispose of all real estate
assets by the end of 1998. As a result, 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 is not recorded on these assets while they are held for
disposal.
 
There were no non-cash investing activities, including real estate acquired
through foreclosure of mortgage loans, in 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.
 
At December 31, 1997, contractual commitments to extend credit under commercial
mortgage loan agreements amounted to approximately $18.7 million. These
commitments generally expire within one year.

At December 31, 1997, scheduled mortgage loan maturities were as follows: 1998
- -- $52.0 million; 1999 -- $17.1 million; 2000 -- $46.3 million; 2001 -- $7.0
million; 2002 -- $11.7 million; and $94.1 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 1997, the Company did not refinance any mortgage loans based
on terms which differed from those granted to new borrowers.

At December 31, 1997, mortgage loans on non-accrual status were $2.8 million,
which were all restructured loans. There were no fixed maturities on non-accrual
status at December 31, 1997. 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 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 $21.1 million and $25.4 million at December 31, 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
$1.9 million and $3.6 million in 1997 and 1996, respectively. Actual interest
income on these loans included in net investment income aggregated $2.1 million
and $2.2 million in 1997 and 1996, respectively.
 
There were no fixed maturities or mortgage loans which were non-income producing
for the twelve months ended December 31, 1997.

5.  FAIR VALUE DISCLOSURES OF FINANCIAL INSTRUMENTS
 
SFAS No. 107, "Disclosures about Fair Value of Financial Instruments", 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 are
limited to the lesser of the present value of the cash flows or book value.

<PAGE>
                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)
 
REINSURANCE RECEIVABLES
 
The carrying amount of the reinsurance receivable for outstanding claims, losses
and loss adjustment expenses reported in the balance sheet approximates fair
value.
 
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:

Gross deferred income tax liabilities totaled $253.7 million and $201.1 million
at December 31, 1997 and 1996. Gross deferred income tax assets totaled $177.8
million and $140.9 at December 31, 1997 and 1996.
 
Management believes, based on the Company's 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, management 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 life-nonlife consolidated
group's federal income tax returns through 1991. The Company is currently
considering its response to certain adjustments proposed by the IRS with respect
to the life-nonlife consolidated group's federal income tax returns for 1989,
1990, and 1991. In management'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.
 
8.  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 $124.1 million and $112.4 million in 1997 and 1996. The
net amounts payable to FAFLIC and affiliates for accrued expenses and various
other liabilities and receivables were $15.0 million and $13.3 million at
December 31, 1997 and 1996.

9.  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 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.
 
At January 1, 1998, AFLIAC could pay dividends of $33.9 million to FAFLIC
without prior approval.
 
10.  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 SFAS No. 113.
 
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.
 
The effects of reinsurance were as follows:

11.  DEFERRED POLICY ACQUISITION EXPENSES
 
The following reflects the changes to the deferred policy acquisition asset:

Balance at end of year......................................    $765.3         $632.7
                                                              ----------     --------
                                                              ----------     --------
</TABLE>
 
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.
 
12.  LIABILITIES FOR INDIVIDUAL ACCIDENT AND HEALTH 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 reflected in
results of operations in the year such changes are determined to be needed and
recorded.
 
The liability for future policy benefits and outstanding claims, losses and loss
adjustment expenses related to the Company's accident and health business was
$219.9 million and $226.2 million at December 31, 1997 and 1996. Accident and
health claim liabilities have been re-estimated for all prior years and were
increased by $-0- million in 1997 and $3.2 million in 1996. Due to the
reinsurance agreement whereby the Company has ceded substantially all of its
accident and health business to the Metropolitan, management 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.
 
13.  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 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 was instituted in Louisiana against Allmerica Financial
Corp. and certain of its subsidiaries 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 refiled the action in Federal
District Court in Worcester, Massachusetts. The plaintiffs

<PAGE>
                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)
 
seek to be certified as a class. The case is in the early stages of discovery
and the Company is evaluating the claims. Although the Company believes it has
meritorious defenses to plaintiffs' claims, there can be no assurance that the
claims will be resolved on a basis which is satisfactory to the Company.
 
The Company has been named a defendant in various legal proceedings arising in
the normal course of business. In the opinion of management, 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.
 
14.  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 for
stock life insurance companies 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 Policyowners of the 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 of changes in net assets present fairly, 
in all material respects, the financial position of each of the Sub-Accounts 
(Value, Growth, International Growth, Global Strategic Income, Global 
Interactive/Telecomm and AIT Money Market) constituting the Fulcrum Separate 
Account of Allmerica Financial Life Insurance and Annuity Company at December 
31, 1997, the results of each of their operations and the changes in each of 
their net assets for the period 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 investments at December 31, 1997 by 
correspondence with the Funds, provide a reasonable basis for the opinion 
expressed above.

                         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 six Sub-Accounts under the Fulcrum Fund variable annuity
contracts. Each Sub-Account invests exclusively in one of five investment
portfolios of The Palladian Trust managed by Palladian Advisors, Inc., or in the
Money Market Fund of the Allmerica Investment Trust (AIT) managed by Allmerica
Investment Management Company, Inc., a wholly-owned subsidiary of First
Allmerica. The Palladian Trust and AIT (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, 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.
 
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 Palladian Trust or AIT. 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 Palladian Trust or AIT at net asset value.
 
    FEDERAL INCOME TAXES -- The Company is taxed as a "life insurance company"
under Subchapter L of the Internal Revenue Code (the Code) and files a
consolidated federal income tax return with First Allmerica. The Company
anticipates no tax liability resulting from the operations of the Separate
Account. Therefore, no provision for income taxes has been charged against the
Separate Account.

NOTE 4 -- RELATED PARTY TRANSACTIONS
 
    The Company makes a charge of 1.25% per annum based on the average daily net
assets of each Sub-Account at each valuation date for mortality and expense
risks. The Company also charges each Sub-Account .20% per annum based on the
average daily net assets of each Sub-Account for administrative expenses. These
charges are deducted from the daily value of each Sub-Account but are paid to
the Company on a monthly basis.
 
    A contract fee of $30 is currently 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. For the period ended December 31, 1997, there were
no contract fees deducted from accumulated value in the Separate Account.
 
    Allmerica Investments, Inc. (Allmerica Investments), a wholly-owned
subsidiary of First Allmerica, is principal underwriter and general distributor
of the Separate Account, and does not receive any compensation for sales of the
contracts. Commissions are paid to registered representatives of Allmerica
Investments by the Company. As the current series of contracts have a contingent
deferred sales charge, no deduction is made for sales charges at the time of the
sale. For the period ended December 31, 1997, there were no contingent deferred
sales charges applicable to the Separate Account.

NOTE 6 -- DIVERSIFICATION REQUIREMENTS
 
    Under the provisions of Section 817(h) of the Internal Revenue 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.

NOTE 8 -- SUBSEQUENT EVENTS
 
    Effective February 12, 1998, Allmerica Investment Management Company, Inc.
(AIMCO) assumed the function of Manager for The Palladian Trust (Trust),
replacing Palladian Advisors, Inc. (PAI). AIMCO's advisory agreement will remain
in effect past June 11, 1998, only if approved by shareholders of the Trust.
AIMCO is an indirect, wholly-owned subsidiary of AFC.
 
    PAI had agreed to limit operating expenses and reimburse those expenses to
the extent that each Portfolio's "other expenses" (i.e., expenses other than
management fees) exceeded certain expense limitations. In January of 1998, PAI
advised the Board of Trustees of the Trust that it did not have sufficient
assets to make the required payment under the expense limitation. On January 28,
1998, a group (consisting of Allmerica Financial Life Insurance and Annuity
Company and certain principals of PAI and entities selling the variable
contracts) offered to make payment of the full amount due under the expense
limitation. The Board of Trustees accepted the offer, and the Trust has been
fully reimbursed for amounts owed under the 1997 expense limitation agreement.
The expense limitations in effect for 1998 have been modified with respect to
certain portfolios of the Trust and these payments are to be made by AIMCO.

     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

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.

RE:  FULCRUM SEPARATE ACCOUNT OF ALLMERICA FINANCIAL 
     LIFE INSURANCE AND ANNUITY COMPANY
     FILE #'S:  333-11377 AND 811-7799

Gentlemen:

In my capacity as Attorney of Allmerica Financial Life Insurance and Annuity
Company (the "Company"), I have participated in the preparation of the
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 individual and group 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 individual and group variable annuity contracts, when issued in
     accordance with the Prospectus contained in 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 judgment are necessary or
appropriate.

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

                                   Very truly yours,

                                   /s/ Lynn Gelinas

     THIS AGREEMENT made as of the 1st day of August, 1998, by and between the
PBHG INSURANCE SERIES FUND, INC. ("FUND"),  a Maryland corporation, PILGRIM
BAXTER & ASSOCIATES, LTD. ("Adviser"), a Delaware corporation, and ALLMERICA

     WHEREAS, FUND is registered with the Securities and Exchange  Commission
("SEC") under the Investment Company Act of 1940, as amended (the "'40 Act"), as
an open-end, diversified management investment company; and

     WHEREAS, FUND is organized as a series fund comprised of several Portfolios
("Portfolios"), with those currently available being listed on Appendix A

     WHEREAS, FUND was organized to act as the funding vehicle for certain

Companies"); and 

     WHEREAS, FUND may also offer its shares to certain qualified pension and

<PAGE>

     WHEREAS, ADVISER is registered with the SEC as an investment adviser under
the Investment Advisers Act of 1940 and as a broker-dealer under the Securities
Exchange Act of 1934, as amended and acts as the FUND's investment adviser; and

     WHEREAS, to the extent permitted by applicable insurance laws and
regulations, LIFE COMPANY intends to purchase shares of FUND to fund the
aforementioned Variable Contracts and FUND is authorized to sell such shares to
LIFE COMPANY at net asset value;

     NOW, THEREFORE, in consideration of their mutual promises, LIFE COMPANY,
FUND, and ADVISER agree as follows:

                           Article I.  SALE OF FUND SHARES
                                       -------------------

     1.1   FUND, so long as this Agreement is in effect, agrees to  make
available in accordance with the terms of this Agreement to the Separate
Accounts of LIFE COMPANY shares of the selected Portfolios as listed on Appendix
B for investment of purchase payments of Variable Contracts allocated to the
designated Separate Accounts as provided in FUND's Registration Statement.

     1.2   FUND agrees to sell to LIFE COMPANY those shares of the selected
Portfolios of FUND which LIFE COMPANY orders, executing such orders on a daily
basis at the net asset value next computed after receipt by FUND or its designee
of the order for the shares of FUND.  For purposes of this Section 1.2, LIFE
COMPANY shall be the designee of FUND for receipt of such orders from the
designated Separate Account and receipt by such designee shall constitute
receipt by FUND; provided that LIFE COMPANY receives the order by the earlier of
(i) 4:00 p.m. New York time or (ii) the close of trading on the floor of the New
York Stock Exchange and FUND receives notice from LIFE COMPANY by telephone or
facsimile (or by such other means as FUND and LIFE COMPANY may agree in writing)
of such order by 9:00 a.m. New York time on the next following Business Day. 
"Business Day" shall mean any day on which the New York Stock Exchange is open
for trading and on which FUND calculates its net asset value pursuant to the
rules of the SEC.

     1.3  FUND agrees to redeem on LIFE COMPANY's request, any full or
fractional shares of FUND held by LIFE COMPANY, executing such requests on a
daily basis at the net asset value next computed after receipt by FUND or its
designee of the request for redemption, in accordance with the provisions of
this agreement and FUND's Registration Statement.  For purposes of this Section
1.3, LIFE COMPANY shall be the designee of FUND for receipt of requests for
redemption from the designated Separate Account and receipt by such designee
shall constitute receipt by FUND; provided that 

                                      2

<PAGE>

LIFE COMPANY receives the request for redemption by the earlier of (i) 4:00 
p.m. New York time or (ii) the close of trading on the floor of the New York 
Stock Exchange and FUND receives notice from LIFE COMPANY by telephone or 
facsimile (or by such other means as FUND and LIFE COMPANY may agree in 
writing) of such request for redemption by 9:00 a.m. New York time on the 
next following Business Day.

     1.4  FUND shall furnish promptly (electronically or by telephone, followed
by written confirmation), notice to LIFE COMPANY of any income dividends or
capital gain distributions payable on the shares of any Portfolio of FUND. LIFE
COMPANY hereby elects to receive all such income dividends and capital gain
distributions as are payable on a Portfolio's shares in additional shares of the
Portfolio. LIFE COMPANY reserves the right to revoke this election and to
receive all such income dividends and capital gain distributions in cash.  FUND
shall notify LIFE COMPANY or its designee of the number of shares so issued as
payment of such dividends and distributions.

     1.5  FUND shall make the net asset value per share for the selected
Portfolio(s) available to LIFE COMPANY on a daily basis as soon as reasonably
practicable  after the net asset value per share is calculated but shall use its
best efforts to make such net asset value available by 7:00 p.m. New York time. 
If FUND provides LIFE COMPANY with materially incorrect share net asset value
information through no fault of LIFE COMPANY, LIFE COMPANY on behalf of the
Separate Accounts, shall be entitled to an adjustment to the number of shares
purchased or redeemed to reflect the correct share net asset value.  Any
material error in the calculation of net asset value per share, dividend or
capital gain information shall be reported promptly upon discovery to LIFE
COMPANY.

     1.6  At the end of each Business Day, LIFE COMPANY shall use the
information described in Section 1.5 to calculate Separate Account unit values
for the day.  Using these unit values, LIFE COMPANY shall process each such
Business Day's Separate Account transactions based on requests and premiums
received by it by the close of trading on the floor of the New York Stock
Exchange (currently 4:00 p.m. New York time) to determine the net dollar amount
of FUND shares which shall be purchased or redeemed at that day's closing net
asset value per share.  The net purchase or redemption orders so determined
shall be transmitted to FUND by LIFE COMPANY by 9:00 a.m. New York Time on the
Business Day next following LIFE COMPANY's receipt of such requests and premiums
in accordance with the terms of Sections 1.2 and 1.3 hereof.

     1.7  If LIFE COMPANY's order requests the purchase of FUND shares, LIFE
COMPANY shall pay for such purchase by wiring federal funds to FUND or its
designated custodial account on the day the order is transmitted by LIFE
COMPANY.  If LIFE COMPANY's order requests a net redemption resulting in a
payment of 

                                      3

<PAGE>

redemption proceeds to LIFE COMPANY, FUND shall use its best efforts to wire 
the redemption proceeds to LIFE COMPANY on the same Business Day, unless 
doing so would require FUND to dispose of Portfolio securities or otherwise 
incur additional costs.  In any event, proceeds shall be wired to LIFE 
COMPANY within three Business Days or such longer period permitted by the '40 
Act or the rules, orders or regulations thereunder and FUND shall notify the 
person designated in writing by LIFE COMPANY as the recipient for such notice 
of such delay by 3:00 p.m. New York Time the same Business Day that LIFE 
COMPANY transmits the redemption order to FUND.
     
     1.8  FUND agrees that all shares of the Portfolios of FUND will be sold
only to  Participating Insurance Companies which have agreed to participate in
FUND to fund their Separate Accounts and/or to Qualified Plans, all in
accordance with the requirements of Section 817(h) of the Internal Revenue Code
of 1986, as amended ("Code") and Treasury Regulation 1.817-5. Shares of the
Portfolios of FUND will not be sold directly to the general public.
     
     1.9  FUND may refuse to sell shares of any Portfolio to any person, or
suspend or terminate the offering of the shares of or liquidate any Portfolio of
FUND if such action is required by law or by regulatory authorities having
jurisdiction or is, in the sole discretion of the Board of Directors of the FUND
(the "Board"), acting in good faith and in light of its duties under federal and
any applicable state laws, deemed necessary, desirable or appropriate and in the
best interests of the shareholders of such Portfolios.

     1.10 Issuance and transfer of Portfolio shares will be by book entry only.
Stock certificates will not be issued to LIFE COMPANY or the Separate Accounts.
Shares ordered from Portfolio will be recorded in appropriate book entry titles
for the Separate Accounts.

to any issuance or sale of the Variable Contracts, will register each Separate

and further that the sale of the Variable Contracts shall comply in all material

to be so treated or that they might not be so treated in the future.

pursuant to this Agreement will be registered under the '33 Act and sold in
accordance with all applicable federal and state laws, and FUND shall be
registered under the '40 Act prior to and at the time of any issuance or sale of

Separate Account intends to elect to be treated as a "regulated investment

reasonable basis for believing it has ceased to so qualify or might not so
qualify in the future.

     2.9  ADVISER represents and warrants that it is and will remain duly
registered and licensed in all material respects under all applicable federal

                   Article III.  PROSPECTUS AND PROXY STATEMENTS
                                 -------------------------------

     3.1  FUND shall prepare and be responsible for filing with the SEC and any
state regulators requiring such filing all shareholder reports, notices, proxy
materials (or similar materials such as voting instruction solicitation
materials), prospectuses and statements of additional information of FUND.  FUND
shall bear the costs of registration and qualification of shares of the
Portfolios, preparation and filing of the documents listed in this Section 3.1
and all taxes and filing fees to which an issuer is subject on the issuance and
transfer of its shares.

     3.2  At least annually, FUND or its designee shall provide LIFE COMPANY,
free of charge, with as many copies of the current prospectus for the shares of
the Portfolios as LIFE COMPANY may reasonably request for distribution to
existing Variable Contract owners whose Variable Contracts are funded by such
shares. FUND or its designee shall provide LIFE COMPANY, at LIFE COMPANY's
expense, with as many copies of the current prospectus for the shares as LIFE
COMPANY may reasonably request for distribution to prospective purchasers of
Variable Contracts. If requested by LIFE COMPANY in lieu thereof, FUND or its
designee shall provide such documentation (including a "camera ready" copy of
the new prospectus as set in type or, at the request of LIFE COMPANY, as a
diskette in the form sent to the financial printer) and other assistance as is
reasonably necessary in order for the parties hereto once a year (or more
frequently if the prospectus for the shares is supplemented or amended) to have
the prospectus for the Variable Contracts and the prospectus for the FUND shares
printed together in one document. The expenses of such printing will be
apportioned between (a) LIFE COMPANY and (b) FUND in proportion to the number of
pages of the Variable Contract and FUND's prospectus, taking account of other
relevant factors affecting the expense of printing, such as covers, columns,
graphs and charts; FUND to bear the cost of printing the FUND's prospectus
portion of such document for distribution only to owners of existing Variable
Contracts funded by the FUND's shares and LIFE COMPANY to bear the expense of
printing the portion of such documents relating to the Separate Account;
provided, however, LIFE COMPANY shall bear all printing expenses of such
combined documents where used for distribution to prospective purchasers or to
owners of existing Variable Contracts not funded by the FUND's shares. In the
event that LIFE COMPANY requests that FUND or its designee provide FUND's
prospectus in a "camera ready" or diskette format, FUND shall be responsible for
providing the prospectus in the format in which it is accustomed to formatting
prospectuses and shall bear the expense of providing the prospectus in such

                                      6

<PAGE>

format (e.g. typesetting expenses), and LIFE COMPANY shall bear the expense of
adjusting or changing the format to conform with any of its prospectuses.

     3.3  FUND will provide LIFE COMPANY with at least one complete copy of all
prospectuses, statements of additional information, annual and semi-annual
reports, proxy statements,   exemptive applications and all amendments or
supplements to any of the above that relate to the Portfolios promptly after the
filing of each such document with the SEC or other regulatory authority.  LIFE
COMPANY will provide FUND with at least one complete copy of all prospectuses,
statements of additional information, annual and semi-annual reports, proxy
statements, exemptive applications and all amendments or supplements to any of
the above that relate to a Separate Account promptly after the filing of each
such document with the SEC or other regulatory authority.

     3.4  The prospectus for the Portfolios shall state that the Statement of
Additional Information for the Portfolios is available from FUND or its
designee.  FUND or its designee, at its expense, shall print and provide such
statement of additional information to LIFE COMPANY (or a master of such
statement suitable for duplication by LIFE COMPANY) for distribution to any
owner of a Variable Contract funded by the Portfolios.  FUND or its designee, at
LIFE COMPANY's expense, shall print and provide such statement to LIFE COMPANY
(or a master of such statement suitable for duplication by LIFE COMPANY) for
distribution to a prospective purchaser who requests such statement or to an
owner of a Variable Contract not funded by the Portfolio.

     3.5  FUND, at its expense, shall provide LIFE COMPANY with copies of its
proxy statements, reports to shareholders, and other communications (except for
prospectus and statements of additional information, which are covered above) to
shareholders in such quantity as LIFE COMPANY shall reasonably require for
distributing to contract owners.  FUND or its designee shall bear the reasonable
cost of printing, duplicating, and mailing of these documents to current
contract owners.

                             Article IV.  SALES MATERIALS
                                          ---------------

     4.1  LIFE COMPANY will furnish, or will cause to be furnished, to  FUND and
ADVISER, each piece of sales literature or other promotional material in which 
FUND or ADVISER is named, at least fifteen (15) Business Days prior to its
intended use.  No such material will be used if FUND or ADVISER objects to its
use in writing within ten (10) Business Days after receipt of such material.

                                      7

<PAGE>

     4.2  FUND and ADVISER will furnish, or will cause to be furnished, to LIFE
COMPANY, each piece of sales literature or other promotional material in which
LIFE COMPANY or its Separate Accounts are named, at least fifteen (15) Business
Days prior to its intended use.  No such material will be used if LIFE COMPANY
objects to its use in writing within ten (10) Business Days after receipt of
such material.

     4.3  FUND and its affiliates and agents shall not give any information or
make any representations on behalf of LIFE COMPANY or concerning LIFE COMPANY,
the Separate Accounts, or the Variable Contracts issued by LIFE COMPANY, other
than the information or representations contained in a registration statement or
prospectus for such Variable Contracts, as such registration statement and
prospectus may be amended or supplemented from time to time, or in reports of
the Separate Accounts or reports prepared for distribution to owners of such
Variable Contracts, or in sales literature or other promotional material
approved by LIFE COMPANY or its designee, except with the written permission of
LIFE COMPANY.

     4.4  LIFE COMPANY and its affiliates and agents shall not give any
information or make any representations on behalf of FUND or concerning FUND
other than the information or representations contained in a registration
statement or prospectus for FUND, as such registration statement and prospectus
may be amended or supplemented from time to time, or in sales literature or
other promotional material approved by FUND or its designee, except with the
written permission of FUND.

     4.5 For purposes of this Agreement, the phrase "sales literature or other
promotional material" or words of similar import include, without limitation,
advertisements (such as material published, or designed for use, in a newspaper,
magazine or other periodical, radio, television, telephone or tape recording,
videotape display, signs or billboards, motion pictures or other public media),
sales literature (such as any written communication distributed or made
generally available to customers or the public, including brochures, circulars,
research reports, market letters, form letters, seminar texts, or reprints or
excerpts of any other advertisement, sales literature, or published article),
educational or training materials or other communications distributed or made
generally available to some or all agents or employees, registration statements,
prospectuses, statements of additional information, shareholder reports and
proxy materials, and any other material constituting sales literature or
advertising under National Association of Securities Dealers, Inc. ("NASD")
rules, the '40 Act or the '33 Act.

                           Article V.  POTENTIAL CONFLICTS
                                       -------------------

     5.1  The parties acknowledge that FUND has filed an application with the
SEC to request an order granting relief from various provisions of the '40 Act
and the rules thereunder to the extent necessary to permit FUND shares to be
sold to and held by Variable Contract separate accounts of both affiliated and
unaffiliated Participating Insurance Companies and Qualified Plans.  It is
anticipated that the Exemptive Order, when and if issued, shall require FUND and
each Participating Insurance Company to comply with conditions and undertakings
substantially as provided in this Section 5.  If the Exemptive Order imposes
conditions materially different from those provided for in this Section 5, the
conditions and undertakings imposed by the Exemptive Order shall govern this
Agreement and the parties hereto agree to amend this Agreement consistent with
the Exemptive Order. The Fund will not enter into a participation agreement with
any other Participating Insurance Company unless it imposes the same conditions
and undertakings as are imposed on LIFE COMPANY hereby.

     5.2  The Board will monitor FUND for the existence of any material
irreconcilable conflict between the interests of Variable Contract owners of all
separate accounts investing in FUND.  An irreconcilable material conflict may
arise for a variety of reasons, which may include: (a) an action by any state
insurance regulatory authority; (b) a change in applicable federal or state
insurance, tax, or securities laws or regulations, or a public ruling, private
letter ruling or any similar action by insurance, tax or securities regulatory
authorities; (c) an administrative or judicial decision in any relevant
proceeding; (d) the manner in which the investments of FUND are being managed;
(e) a difference in voting instructions given by Variable Contract owners; (f) a
decision by a Participating Insurance Company to disregard the voting
instructions of Variable Contract owners and (g) if applicable, a decision by a
Qualified Plan to disregard the voting instructions of plan participants.

     5.3  LIFE COMPANY will report any potential or existing conflicts, of which
it is aware, to the Board.  LIFE COMPANY will be responsible for assisting the
Board in carrying out its duties in this regard by providing the Board with all
information reasonably necessary for the Board to consider any issues raised. 
The responsibility includes, but is not limited to, an obligation by the LIFE
COMPANY to inform the Board whenever it has determined to disregard  Variable
Contract owner voting instructions.  These responsibilities of LIFE COMPANY 
will be carried out with a view only to the interests of the Variable Contract
owners.

     5.4  If a majority of the Board or majority of its disinterested Directors,
determines that a material irreconcilable conflict exists affecting LIFE
COMPANY, LIFE COMPANY, at its expense and to the extent reasonably practicable
(as determined by 

                                      9

<PAGE>

a majority of the Board's disinterested Directors), will take any steps 
necessary to remedy or eliminate the irreconcilable material conflict, 
including; (a) withdrawing the assets allocable to some or all of the 
Separate Accounts from FUND or any Portfolio thereof and reinvesting those 
assets in a different investment medium, which may include another Portfolio 
of FUND, or another investment company; (b) submitting the question as to 
whether such segregation should be implemented to a vote of all affected 
Variable Contract owners and as appropriate, segregating the assets of any 
appropriate group (i.e variable annuity or variable life insurance Contract 
owners of one or more Participating Insurance Companies) that votes in favor 
of such segregation, or offering to the affected Variable Contract owners the 
option of making such a change; and (c) establishing a new registered 
management investment company (or series thereof) or managed separate 
account.  If a material irreconcilable conflict arises because of LIFE 
COMPANY's decision to disregard Variable Contract owner voting instructions, 
and that decision represents a minority position or would preclude a majority 
vote, LIFE COMPANY may be required, at the election of FUND, to withdraw the 
Separate Account's investment in FUND, and no charge or penalty will be 
imposed as a result of such withdrawal.  The responsibility to take such 
remedial action shall be carried out with a view only to the interests of the 
Variable Contract owners and shall be limited to the extent required by the 
foregoing irreconcilable material conflict as determined by a majority of the 
disinterested members of the Board.

     For the purposes of this Section 5.4, a majority of the disinterested
members of the Board shall determine whether or not any proposed action
adequately remedies any irreconcilable material conflict but in no event will
FUND or ADVISER (or any other investment adviser of FUND) be required to
establish a new funding medium for any Variable Contract.  Further, LIFE COMPANY
shall not be required by this Section 5.4 to establish a new funding medium for
any Variable Contracts if any offer to do so has been declined by a vote of a
majority of Variable Contract owners materially and adversely affected by the
irreconcilable material conflict.

     5.5  The Board's determination of the existence of an irreconcilable
material conflict and its implications shall be made known promptly and in
writing to LIFE COMPANY.

     5.6  No less than annually, LIFE COMPANY shall submit to the Board such
reports, materials or data as the Board may reasonably request so that the Board
may fully carry out its obligations.  Such reports, materials, and data shall be
submitted more frequently if deemed appropriate by the Board.

                                 Article VI.  VOTING
                                              ------

     6.1  LIFE COMPANY will provide pass-through voting privileges to all
Variable Contract owners so long as the SEC continues to interpret the '40 Act
as requiring pass-through voting privileges for Variable Contract owners. 
Accordingly, LIFE COMPANY, where applicable, will vote shares of the Portfolio
held in its Separate Accounts in a manner consistent with voting instructions
timely received from its Variable Contract owners.  LIFE COMPANY will be
responsible for assuring that each of its Separate Accounts that participates in
FUND calculates voting privileges in a manner consistent with other
Participating Insurance Companies or the Exemptive Order. LIFE COMPANY will vote
shares for which it has not received timely voting instructions, as well as
shares it owns, in the same proportion as its votes those shares for which it
has received voting instructions.

     6.2  If and to the extent Rule 6e-2 and Rule 6e-3(T) are amended, or if
Rule 6e-3 is adopted, to provide exemptive relief from any provision of the '40
Act or the rules thereunder with respect to mixed and shared funding on terms
and conditions materially different from any exemptions granted in the Exemptive
Order, then FUND,  and/or the Participating Insurance Companies, as appropriate,
shall take such steps as may be necessary to comply with Rule 6e-2 and Rule
6e-3(T), as amended, and Rule 6e-3, as adopted, to the extent such Rules are
applicable.

                            Article VII.  INDEMNIFICATION
                                          ---------------

     7.1   INDEMNIFICATION BY LIFE COMPANY.  LIFE COMPANY agrees to indemnify
and hold harmless FUND, ADVISER and each of their directors, principals,
officers, employees and agents and each person, if any, who controls FUND or
ADVISER within the meaning of Section 15 of the '33 Act (collectively, the
"Indemnified Parties" for purposes of this Article VII) against any and all
losses, claims, damages, liabilities (including amounts paid in settlement with
the written consent of LIFE COMPANY, which consent shall not be unreasonably
withheld) or litigation (including legal and other expenses), to which the
Indemnified Parties may become subject under any statute, regulation, at common
law or otherwise, insofar as such losses, claims, damages, liabilities or
expenses (or actions in respect thereof) or settlements are related to the sale
or acquisition of FUND's shares or the Variable Contracts and:

     (a)  arise out of or are based upon any untrue statements or alleged untrue
          statements of any material fact contained in the Registration
          Statement or prospectus for the Variable Contracts or contained in the
          Variable Contracts (or any amendment or supplement to any of the
          foregoing), or arise out of or are based upon the omission or the
          alleged omission to 

                                      11

<PAGE>

          state therein a material fact required to be stated therein or 
          necessary to make the statements therein not misleading, provided 
          that this agreement to indemnify shall not apply as to any 
          Indemnified Party if such statement or omission or such
          alleged statement or omission was made in reliance upon and in
          conformity with information furnished to LIFE COMPANY by or on behalf
          of FUND for use in the registration statement or prospectus for the
          Variable Contracts or in the Variable Contracts or sales literature
          (or any amendment or supplement) or otherwise for use in connection
          with the sale of the Variable Contracts or FUND shares; or 

     (b)  arise out of or as a result of statements or representations (other
          than statements or representations contained in the registration
          statement, prospectus or sales literature of FUND not supplied by LIFE
          COMPANY, or persons under its control) or wrongful conduct of LIFE
          COMPANY or persons under its control, with respect to the sale or
          distribution of the Variable Contracts or FUND shares; or

     (c)  arise out of any untrue statement or alleged untrue statement of a
          material fact contained in a registration statement, prospectus, or
          sales literature of FUND or any amendment thereof or supplement
          thereto or the omission or alleged omission to state therein a
          material fact required to be stated therein or necessary to make the
          statements therein not misleading if such statement or omission or
          such alleged statement or omission was made in reliance upon and in
          conformity with information furnished to FUND by or on behalf of LIFE
          COMPANY; or

     (d)  arise as a result of any failure by LIFE COMPANY to provide
          substantially the services and furnish the materials under the terms
          of this Agreement; or

     (e)  arise out of or result from any material breach of any representation
          and/or warranty made by LIFE COMPANY in this Agreement or arise out of
          or result from any other material breach of this Agreement by LIFE
          COMPANY.

     7.2   LIFE COMPANY shall not be liable under this indemnification provision
with respect to any losses, claims, damages, liabilities or litigation incurred
or assessed against an Indemnified Party as such may arise from such Indemnified
Party's willful misfeasance, bad faith, or negligence in the performance of such
Indemnified Party's duties or by reason of such Indemnified Party's reckless
disregard of obligations or duties under this Agreement.

                                      12

<PAGE>

     7.3   LIFE COMPANY shall not be liable under this indemnification provision
with respect to any claim made against an Indemnified Party unless such
Indemnified Party shall have notified LIFE COMPANY in writing within a
reasonable time after the summons or other first legal process giving
information of the nature of the claim shall have been served upon such
Indemnified Party (or after such Indemnified Party shall have received notice of
such service on any designated agent), but failure to notify LIFE COMPANY of any
such claim shall not relieve LIFE COMPANY from any liability which it may have
to the Indemnified Party against whom such action is brought otherwise than on
account of this indemnification provision.  In case any such action is brought
against an Indemnified Party, LIFE COMPANY shall be entitled to participate at
its own expense in the defense of such action.  LIFE COMPANY also shall be
entitled to assume the defense thereof, with counsel satisfactory to the party
named in the action.  After notice from LIFE COMPANY to such party of LIFE
COMPANY's election to assume the defense thereof, the Indemnified Party shall
bear the fees and expenses of any additional counsel retained by it, and LIFE
COMPANY will not be liable to such party under this Agreement for any legal or
other expenses subsequently incurred by such party independently in connection
with the defense thereof other than reasonable costs of investigation.

     7.4   INDEMNIFICATION BY ADVISER. ADVISER agrees to indemnify and hold
harmless LIFE COMPANY and each of its directors, officers, employees, and agents
and each person, if any, who controls LIFE COMPANY within the meaning of Section
15 of the '33 Act (collectively, the "Indemnified Parties" for the purposes of
this Article VII) against any and all losses, claims, damages, liabilities
(including amounts paid in settlement with the written consent of ADVISER which
consent shall not be unreasonably withheld) or litigation (including legal and
other expenses) to which the Indemnified Parties may become subject under any
statute, or regulation, at common law or otherwise, insofar as such losses,
claims, damages, liabilities or expenses (or actions in respect thereof) or
settlements are related to the sale or acquisition of FUND's shares or the
Variable Contracts and:

     (a)  arise out of or are based upon any untrue statement or alleged untrue
          statement of any material fact contained in the registration statement
          or prospectus or sales literature of FUND (or any amendment or
          supplement to any of the foregoing), or arise out of or are based upon
          the omission or the alleged omission to state therein a material fact
          required to be stated therein or necessary to make the statements

          FUND or in sales literature (or any amendment or supplement) or 
          otherwise for use in connection with the sale of the Variable 
          Contracts or FUND shares; or 

     (b)  arise out of or as a result of statements or representations (other
          than statements or representations contained in the registration

          shares; or

     (c)  arise out of any untrue statement or alleged untrue statement of a
          material fact contained in a registration statement, prospectus, or
          sales literature covering the Variable Contracts, or any amendment
          thereof or supplement thereto or the omission or alleged omission to

     (e)  arise out of or result from any material breach of any representation
          and/or warranty made by ADVISER in this Agreement or arise out of or
          result from any other material breach of this Agreement by ADVISER.

     7.5   ADVISER shall not be liable under this indemnification provision with
respect to any losses, claims, damages, liabilities or litigation to which an
Indemnified Party would otherwise be subject by reason of such Indemnified
Party's willful misfeasance, bad faith, or  negligence in the performance of
such Indemnified Party's duties or by reason of such Indemnified Party's
reckless disregard of obligations and duties under this Agreement.

     7.6   ADVISER shall not be liable under this indemnification provision with
respect to any claim made against an Indemnified Party unless such Indemnified
Party shall have notified ADVISER in writing within a reasonable time after the
summons or other first legal process giving information of the nature of the
claim shall have been served upon such Indemnified Party (or after such
Indemnified Party shall have received notice of such service on any designated
agent), but failure to notify ADVISER of any such claim shall not relieve
ADVISER from any liability which it may have to the Indemnified Party against
whom such action is brought otherwise than on account of this indemnification
provision.  In case any such action is brought against the Indemnified Parties,
ADVISER shall be entitled to participate at its own expense in the defense
thereof.  ADVISER also shall be entitled to assume the defense thereof, with
counsel satisfactory to the party named in the action.  After notice from
ADVISER to such party of ADVISER's election to assume the defense thereof, the
Indemnified Party shall bear the fees and expenses of any additional counsel
retained by it, and ADVISER will not be liable to such party under this
Agreement for any legal or other expenses subsequently incurred by such party
independently in connection with the defense thereof other than reasonable costs
of investigation.

                           Article VIII.  TERM; TERMINATION
                                          -----------------

     8.1  This Agreement shall be effective as of the date hereof and shall
continue in force until terminated in accordance with the provisions herein.

     8.2  This Agreement shall terminate in accordance with the following
provisions:

     (a)  At the option of LIFE COMPANY or FUND at any time from the date hereof
          upon 60 days' notice, unless a shorter time is agreed to by the
          parties;

     (b)  At the option of LIFE COMPANY, if FUND shares are not reasonably
          available to meet the requirements of the Variable Contracts as
          determined by LIFE COMPANY.  Prompt notice of election to terminate
          shall be furnished by LIFE COMPANY, said termination to be effective
          ten days after receipt of notice unless  FUND makes available a
          sufficient number of shares to reasonably meet the requirements of the
          Variable Contracts within said ten-day period;

                                      15

<PAGE>

     (c)  At the option of LIFE COMPANY, upon the institution of formal
          proceedings against FUND by the SEC, the NASD, or any other regulatory
          body, the expected or anticipated ruling, judgment or outcome of which
          would, in LIFE COMPANY's reasonable judgment, materially impair FUND's
          ability to meet and perform FUND's obligations and duties hereunder. 
          Prompt notice of election to terminate shall be furnished by LIFE
          COMPANY with said termination to be effective upon receipt of notice;

     (d)  At the option of FUND, upon the institution of formal proceedings
          against LIFE COMPANY by the SEC, the NASD, or any other regulatory
          body, the expected or anticipated ruling, judgment or outcome of which
          would, in  FUND's reasonable judgment, materially impair LIFE
          COMPANY's ability to meet and perform its obligations and duties
          hereunder.  Prompt notice of election to terminate shall be furnished
          by FUND with said termination to be effective upon receipt of notice;

     (e)  In the event FUND's shares are not registered, issued or sold in
          accordance with applicable state or federal law, or such law precludes
          the use of such shares as the underlying investment medium of Variable
          Contracts issued or to be issued by LIFE COMPANY.  Termination shall
          be effective upon receipt of notice by LIFE COMPANY;

     (f)  At the option of FUND if the Variable Contracts cease to qualify as
          annuity contracts or life insurance contracts, as applicable, under
          the Code, or if FUND reasonably believes that the Variable Contracts
          may fail to so qualify.  Termination shall be effective upon receipt
          of notice by LIFE COMPANY;

     (g)  At the option of LIFE COMPANY, upon FUND's breach of any material
          provision of this Agreement, which breach has not been cured to the
          satisfaction of LIFE COMPANY within ten days after written notice of
          such breach is delivered to FUND;

     (h)  At the option of FUND, upon LIFE COMPANY's breach of any material
          provision of this Agreement, which breach has not been cured to the
          satisfaction of FUND within ten days after written notice of such
          breach is delivered to LIFE COMPANY;

                                      16

<PAGE>

     (i)  At the option of FUND, if the Variable Contracts are not registered,
          issued or sold in accordance with applicable federal and/or state law.
          Termination shall be effective immediately upon receipt of notice by
          LIFE COMPANY;

     (j)  In the event this Agreement is assigned without the prior written
          consent of  LIFE COMPANY, FUND, and ADVISER,  termination shall be
          effective immediately upon receipt of notice;

     (k)  At the option of LIFE COMPANY with respect to any Portfolio in the
          event that such Portfolio ceases to qualify as a Regulated Investment
          Company under Subchapter M of the Code or under any successor or
          similar provision, or if LIFE COMPANY reasonably believes that the
          FUND may fail to so qualify.  Termination shall be effective
          immediately upon receipt of notice;

     (l)  At the option of LIFE COMPANY with respect to any Portfolio in the
          event that such Portfolio fails to meet the diversification
          requirements specified in Article 2.6.  Termination shall be effective
          immediately upon receipt of notice.

     8.3  Notwithstanding any termination of this Agreement pursuant to Section
8.2 hereof, FUND shall, at the option of LIFE COMPANY, continue to make
available additional FUND shares, as provided below, pursuant to the terms and
conditions of this Agreement, for all Variable Contracts in effect on the
effective date of termination of this Agreement (hereinafter referred to as
"Existing Contracts").  Specifically, without limitation, if LIFE COMPANY so
elects, the owners of the Existing Contracts or LIFE COMPANY, whichever shall
have legal authority to do so, shall be permitted to reallocate investments in
FUND, redeem investments in FUND and/or invest in FUND upon the payment of
additional premiums under the Existing Contracts.  In the event of a termination
of this Agreement pursuant to Section 8.2  hereof, LIFE COMPANY, as promptly as
is practicable under the circumstances, shall notify FUND AND ADVISER whether
LIFE COMPANY elects to have FUND continue to make FUND shares available after
such termination.  If FUND shares continue to be made available after such
termination, the provisions of this Agreement shall remain in effect and
thereafter either FUND or LIFE COMPANY may terminate the Agreement, as so
continued pursuant to this Section 8.3, upon sixty (60) days prior written
notice to the other party.

     8.4 Except as necessary to implement Variable Contract owner initiated
transactions, or as required by state insurance laws or regulations,  LIFE
COMPANY shall not redeem the shares attributable to the Variable Contracts (as
opposed to the 

                                      17

<PAGE>

shares attributable to LIFE COMPANY's assets held in the Separate Accounts), 
and LIFE COMPANY shall not prevent Variable Contract owners from allocating 
payments to a Portfolio that was otherwise available under the Variable 
Contracts until thirty (30) days after the LIFE COMPANY shall have notified 
FUND of its intention to do so.

                                 Article IX.  NOTICES
                                              -------

reference only and in no way define or delineate any of the provisions hereof or
otherwise affect their construction or effect.

     10.2  This Agreement may be executed simultaneously in two or more
