</TABLE>
--------------------------------------------------------------------------------
--------------------------------------------------------------------------------
In the section entitled "Definitions," the definition of "Commuted Value" is
deleted and replaced with the following:
COMMUTED VALUE: The present value of any remaining guaranteed Annuity Payouts.
This amount is calculated using the Assumed Investment Return for variable
dollar amount Annuity Payouts or the underlying rate of return for fixed dollar
amount Annuity Payouts.
In the "Highlights" section under the sub-section "Can I take out any of my
money?", the first paragraph is deleted and replaced with the following
language:
You may Surrender all or part of the amounts you have invested at any time
before we start making Annuity Payouts. Once Annuity Payouts begin, you may take
full or partial Surrenders under the Payments for a Designated Period, or Life
Annuity with 120, 180 or 240 Monthly Payments Certain Annuity Payout Options,
but only if you selected the variable dollar amount Annuity Payouts.
--------------------------------------------------------------------------------
- You may have to pay income tax on the money you take out and, if you
Surrender before you are age 59 1/2, you may have to pay an income tax
penalty.
- You may have to pay a Contingent Deferred Sales Charge on the money you
Surrender.
--------------------------------------------------------------------------------
In the "Highlights" section, under the subsection "What Annuity Payout Options
are available?" the second paragraph is deleted and replaced with the following:
You must begin to take payments before the Annuitant's 90th birthday or the
end of the 10th Contract Year, whichever comes later, unless you elect a
later date to begin receiving payments subject to the laws and regulations
then in effect and our approval. If you do not tell us what Annuity Payout
Option you want before that time, we will pay you under the variable Life
Annuity with 120, 180 or 240 Monthly Payments Certain Annuity Payout Option
with period certain payouts for 120 months. Please consult your Registered
Representative or call us.
In the "General Contract Information" section, immediately under the table
entitled "Hartford's Ratings" the following paragraph is added:
These ratings apply to Hartford's ability to meet its obligations under the
Contract. The ratings do not apply to the Separate Account or the underlying
Funds.
In the "Surrenders" section, under the sub-section entitled "What kinds of
surrenders are available?", the paragraph entitled "Partial Surrenders after the
Annuity Commencement Date" is deleted and replaced with the following language:
PARTIAL SURRENDERS AFTER THE ANNUITY COMMENCEMENT DATE -- Partial Surrenders are
permitted after the Annuity Commencement Date if you select the Life Annuity
with 120, 180 or 240 Monthly Payments Certain or the Payments for a Designated
Period Annuity Payout Options. You may take partial Surrenders of amounts equal
to the Commuted Value of the payments that we would have made during the "Period
Certain" or the number of years you select under the Annuity Payout Option that
we guarantee to make Annuity Payouts.
To qualify for partial Surrenders under these Annuity Payout Options you must
elect a variable dollar amount Annuity Payout and you must make the Surrender
request during the Period Certain.
Hartford will deduct any applicable Contingent Deferred Sales Charges.
If you elect to take the entire Commuted Value of the Annuity Payouts we would
have made during the Period Certain, Hartford will not make any Annuity Payouts
during the remaining Period Certain. If you elect to take only some of the
Commuted Value of the Annuity Payouts we would have made during the Period
Certain, Hartford will reduce the remaining Annuity Payouts during the remaining
Period Certain. Annuity Payouts that are to be made after the Period Certain is
over will not change.
PLEASE CHECK WITH YOUR TAX ADVISER BECAUSE THERE COULD BE ADVERSE TAX
CONSEQUENCES FOR PARTIAL SURRENDERS AFTER THE ANNUITY COMMENCEMENT DATE.
In the "Death Benefit" section, in the first paragraph of the sub-section
entitled "What is the Death Benefit and how is it calculated?", the first
sentence is deleted and replaced with the following:
The Death Benefit is the amount we will pay upon the death of the Contract
Owner, joint Owner or Annuitant.
In the "Death Benefit" section, the sub-section entitled "Who will receive the
Death Benefit?" is deleted and replaced with the following language:

Option do you want to use?" under the subsection "Important Information", that
last two bulleted paragraphs are deleted and replaced with the following:

Annuity Payout Option with period certain payouts for 120 months.
