ALLMERICA FINANCIAL LIFE INSURANCE AND ANNUITY COMPANY

                            TERM LIFE INSURANCE RIDER


DESCRIPTION: This rider is part of the policy to which it is attached if it is
shown in the specifications page of the policy. The insured under this rider is
shown on the Term Insurance Schedule Page.

BENEFIT: We will pay the term insurance upon receipt of due proof that the
insured died prior to the term expiry date, while the rider is in force. Unless
otherwise requested, the term insurance benefit will be paid to the same
beneficiary who receives the policy's net death benefit.

The amount of the term insurance benefit may vary. The benefit will be
determined on each monthly processing date while the rider is in force. The term
insurance benefit amount will be the lesser of:

- -    the term insurance amount (as shown in the Term Insurance Schedule Page);
     or

- -    the term insurance amount less the excess of the minimum death benefit of
     the policy over the policy face amount (plus the policy value if the Death
     Benefit Option 2 is in effect).

The Term Insurance Schedule Page will display the following information:

- -    the name and age of the insured;

- -    the term insurance amount;

- -    the effective date of the term insurance;

- -    the term expiry date.

CHANGE PROVISIONS: You may decrease the amount of term insurance if the request
is made:

- -    during the lifetime of the insured; and

- -    in writing while the policy and term rider are in force

A request to decrease the amount of term insurance will be effective on the
monthly processing date following the date of the written request. A
supplemental Term Insurance Schedule will be issued. The schedule will include
the following information:

- -    effective date of the decrease in amount of term insurance.

- -    the amount of the decrease in term insurance, and the remaining term
     insurance amount.

- -    the remaining term insurance amount.

The company reserves the right to establish a minimum limit for the amount of
any decrease.

CONTESTABILITY: Except for failure to pay premiums, this rider cannot be
contested after the term insurance has been in force during the insured's
lifetime for two years from the date of issue.

SUICIDE EXCLUSION: The risk of suicide of the insured, while sane or insane,
within two years of the issue date of this rider is not assumed. The beneficiary
will receive the sum of the term charges paid.

MISSTATEMENT OF AGE OR SEX: If the age or sex of the insured is misstated, the
amount payable under this rider will be such that the charges paid on the last
monthly processing date would have purchased at the insured's correct age or
sex. No adjustment will be made if the insured's underwriting class is unisex
and there has been a misstatement of sex.

CHARGES: The monthly term insurance charge will be the term rider benefit amount
as of the current monthly processing date, divided by 1,000 and multiplied by
the term insurance rate shown in the Term Insurance Schedule.
