ALLMERICA FINANCIAL LIFE INSURANCE AND ANNUITY COMPANY
             OPTION TO ACCELERATE DEATH BENEFITS ENDORSEMENT

This rider is a part of the policy to which it is attached. The insured under
this rider is the insured under the policy. This rider does not apply to any
benefits provided by rider.

BENEFIT - While this rider is in force, you may elect to receive a portion of
the net death benefit, called the "living benefit," prior to the insured's death
under either the terminal illness option or the nursing home option, subject to
the definitions, conditions and limitations in this endorsement.  This option
may only be exercised once.

DEFINITIONS - "Option amount" means that portion of the death benefit which you
elect to apply under this option. The option amount must be at least $25,000 and
may not exceed the lesser of:

- -  one-half of the death benefit on the date the option is elected; or
- -  the amount that would reduce the face amount to our minimum issue limit for
   this policy; or
- -  $250,000.

"Option percentage" is the option amount divided by the death benefit.

"Living benefit" is the option amount which has been reduced for interest and
other factors.  It is equal to the lump sum benefit under this rider, and is the
amount used to determine the monthly benefit.  The living benefit will not be
less than the surrender value of the policy multiplied by the option percentage.
The following factors will be used to calculate the living benefit:

- -  age;
- -  sex, unless the policy is issued on a unisex basis;
- -  life expectancy;
- -  policy value;
- -  outstanding loan;
- -  rate of interest currently being credited to the Fixed Account, including
   those values which are subject to outstanding loan;
- -  face amount;
- -  death benefit option;
- -  current insurance protection charges;
- -  administrative charges; and
- -  an expense charge of $150.

An amount equal to the outstanding loan multiplied by the option percentage will
be deducted from the living benefit. The remaining outstanding loan will
continue in force.

The assumptions we use to calculate the living benefit may change from time to
time.  The factors used to compute the living benefit will be set and changed
only prospectively; that is, based on changes in future expectations. We will
not change these factors to recoup any prior losses or distribute past gains
under the rider.

"Eligible nursing home" means an institution or special nursing unit of a
hospital which meets at least one of the following requirements:

I.    it is Medicare - approved as a provider of skilled nursing care services;
      or

II.   it is licensed as a skilled nursing home or as an intermediate care
      facility by the state in which it is located; or

III.  it meets all the requirements listed below:

      -  it is licensed as a nursing home by the state in which it is located;

      -  its main function is to provide skilled, intermediate or custodial
      nursing care;

      - it is engaged in providing continuous room and board accommodations
      to 3 or more persons;

      -  it is under the supervision of a registered nurse (RN) or licensed
      practical nurse (LPN);

      -  it maintains a daily medical record of each patient; and

      -  it maintains control and records for all medications dispensed.

Institutions which primarily provide residential facilities are not eligible
nursing homes.

"Proof of claim satisfactory to us" shall include:

- -  a request signed by the insured to disclose all facts concerning the
   insured's health;

Form 1033-99
                                      1



- -  records of the attending physician, including a prognosis of the insured;
   and

- -  if we request, a medical examination of the insured at our expense conducted
   by a physician we choose.

CONDITIONS - Upon written request you may elect to receive payment under one
of the accelerated death benefit options subject to the following conditions:

- -  the policy is in force;

- -  a written consent has been given by any collateral assignee, irrevocable
   beneficiary and the insured if you are not the insured; and

- -  the insured qualifies for the option you elect.

TERMINAL ILLNESS OPTION - If you provide proof of claim satisfactory to us
that the insured's life expectancy is 12 months or less, you may elect to
receive equal monthly payments for 12 months.  For each $1,000 of living
benefit, each payment will be at least $85.21. This assumes an annual
interest rate of 5%.

If the insured dies before all the payments have been made, we will pay the
beneficiary in one sum the present value of the remaining payments due under
this rider calculated at the interest rate we use to determine those payments.

If you do not wish to receive monthly payments, you may elect to receive an
amount equal to the living benefit in a lump sum.

NURSING HOME OPTION - If (1) the insured is confined to an eligible nursing
home and has been confined there continuously for the preceding six months;
and (2) you provide proof of claim satisfactory to us that the insured is
expected to remain in the nursing home until death, you may elect level
monthly payments for the number of years shown in the table that follows.
For each $1,000 of living benefit, each payment will be at least the minimum
amount shown in that table. The table assumes an annual interest rate of 5%.

If the insured dies before all the payments have been made, we will pay the
beneficiary in one sum the present value of the remaining payments due under
this rider calculated at the interest rate we use to determine those payments.

You may elect a longer payment period than that shown in the table.  If you
do, monthly payments will be reduced so that the present value of the monthly
payments for the longer payment period is equal to the present value of the
payments for the period shown in the table, calculated at an interest rate of
at least 5%.

EFFECT ON POLICY - The policy's death benefit will be decreased by the option
amount.  Such decrease will be effective on the monthly payment processing
date following the date of the written request. Existing insurance will be
decreased or eliminated in the following order:

- -  first, the most recent increase;

- -  second, the next most recent increases successively; and

- -  last, the initial face amount.

surrender charge applicable to the decrease in the face amount will be waived.
The amount of the charge which is waived will be:

- -  the surrender charge applicable to any increased face amount which is
   eliminated in the order set forth above; plus

- -  a pro rata share of the surrender charge applicable to a partial reduction in
   an increase or in the original face amount.

New specification pages will be issued.  These pages will include the following
information:

- -  the effective date of the decrease;

- -  the amount of the decrease and the benefit remaining in force;

- -  the revised surrender charge;

- -  the revised minimum monthly factor, if any; and

- -  the new guideline premiums.

The policy value will be reduced in the same proportion as the reduction in
the death benefit.  Riders will continue in force.

FIRST TO DIE POLICY - The following provisions apply if this rider is attached
to a First to Die Flexible Premium Adjustable Life Insurance Policy: The
"insured" shall mean the first insured to qualify for benefits under this rider.
No additional living benefits will be provided if other insureds qualify prior
to the death of the first insured to die. If the first to die under the policy
is not the first insured to qualify under this rider, the net death benefit as
adjusted by this rider will be paid to the beneficiary of the policy and payment
of the living benefit will continue as provided in this rider.

EXCLUSION - No benefit will be paid under this rider if a claim results,
directly or indirectly, from a suicide attempt or a self-inflicted injury (while
sane or insane) for any period during which a suicide exclusion is applicable.

TERMINATION - This endorsement will terminate on the first to occur of:

- - the end of the grace period of a premium in default; or

- - the termination or maturity of the policy while the insured is alive; or

- - at any time on your written request.

GENERAL - The specification pages (page 3 or 3.1 of the policy) will show the
date of issue of this rider.

The living benefit will be made available to you on a voluntary basis only.
Accordingly:

a) If you are required by law to exercise this option to satisfy the claim of
   creditors, whether in bankruptcy or otherwise, you are not eligible for this
   benefit.

b) If you are required by a government agency to exercise this option in order
   to apply for, obtain, or retain a government benefit or entitlement, you are
   not eligible for this benefit.

Except as otherwise provided, all conditions and provisions of the policy apply
to this endorsement.
