PREFERRED LOAN OPTION
---------------------
The following is inserted under the Section "LOAN PRIVILEGE" in the SUMMARY
and as the last section under POLICY LOANS:
PREFERRED LOAN OPTION - A preferred loan option is available under the
Policies. The preferred loan option will be available upon written
request. It may be revoked by you at any time. If this option has been
selected, after the tenth policy anniversary Policy Value in the General
Account equal to the loan amount will be credited with interest at an
effective annual yield of at least 7.5%. Our current practice is to
credit a rate of interest equal to the rate being charged for the
preferred loan.
There is some uncertainty as to the tax treatment of preferred loans.
Consult a qualified tax adviser (and see "FEDERAL TAX CONSIDERATIONS").
THE PREFERRED LOAN OPTION IS NOT AVAILABLE IN ALL STATES.
The following replaces the third paragraph under "FEDERAL TAX CONSIDERATIONS
- - TAXATION OF THE POLICIES":
The Company believes that non-preferred loans received under a Policy
will be treated as indebtedness of the policy owner for federal income
tax purposes. Under current law, these loans will not constitute
income for the Policyowner while the Policy is in force (but see
"MODIFIED ENDOWMENT POLICIES"). However, there is a risk that a
preferred loan may be characterized by the IRS as a withdrawal and
taxed accordingly. At the present time, the IRS has not issued any
guidance on whether loans with the attributes of a preferred loan
should be treated differently than a non-preferred loan. This lack of
specific guidance makes the tax treatment of preferred loans uncertain.
In the event IRS guidelines are issued in the future, you may revoke
your request for a preferred loan.
Section 264 of the Internal Revenue Code restricts the deduction of
interest on Policy loans. Consumer interest paid on Policy loans under
an individually owned Policy is not tax deductible. No tax deduction
for interest is allowed on Policy loans exceeding $50,000 in aggregate,
if the Insured is an officer or employee of, or is financially
interested in, any business carried on by the taxpayer.

TWELVE TRANSFERS WITHOUT CHARGE
-------------------------------
The sections "SUMMARY - Transfer Charge," "THE POLICY - Transfer Privilege,"
"CHARGES AND DEDUCTIONS - DOLLAR COST AVERAGING OPTION AND AUTOMATIC
REBALANCING OPTION," and "MORE INFORMATION ABOUT THE GENERAL ACCOUNT --
TRANSFERS, SURRENDERS, PARTIAL WITHDRAWALS AND POLICY LOANS," are amended to
indicate that the first twelve transfers of Policy Value in a Policy year,
rather than the first six transfers, will be free of charge.

PAID-UP INSURANCE OPTION
------------------------
Effective January 6, 1997, upon written request a Policyowner may exercise a
paid-up insurance option. Paid-up life insurance is fixed insurance, usually
having a reduced face amount, for the lifetime of the insured with no
further premiums due. If the Policyowner elects this option, certain
Policyowner rights and benefits may be limited.
The paid-up fixed insurance will be in the amount that the surrender value of
the Policy can purchase for a net single premium at the Insured's age and
underwriting class on the date this option is elected. The Company will
transfer any policy value in the Variable Account to the General Account on
the date it receives the written request to elect the option. If the
surrender value exceeds the net single premium, the Company will pay the
excess to the Policyowner. The net single premium is based on the
Commissioners 1980 Standard Ordinary Mortality Tables, Smoker or Non-Smoker
(Table B for unisex policies) with increases in the tables for non-standard
risks. Interest will not be less than 4.5%.
IF THE PAID-UP INSURANCE OPTION IS ELECTED, THE FOLLOWING POLICYOWNER RIGHTS
AND BENEFITS WILL BE AFFECTED:
- - As described above, the paid-up insurance benefit is computed
differently from the net death benefit, and the death benefit options
will not apply.
- - The Company will transfer the policy value in the Variable Account to
the General Account on the date it receives the written request to
elect the option. The Company will not allow transfers of policy value
from the General Account back to the Variable Account.
- - The Policyowner may not make further payments.
- - The Policyowner may not increase or decrease the face amount or make
partial withdrawals.
- - Riders will continue only with the Company's consent.
After electing paid-up fixed insurance, the Policyowner may surrender the
Policy for its net cash value. The cash value is equal to the net single
premium for paid-up insurance at the Insured's attained age. The net cash
value is the cash value less any outstanding loans.
