Account MGA II.

2. The following information replaces the section entitled "SEPARATE ACCOUNT" on
page 16:

SEPARATE ACCOUNT MGA

Purchase Payments made to this Contract are invested in Separate Account MGA. We
have exclusive and absolute ownership and control of the assets of Separate
Account MGA. It is a non-unitized Separate Account and, to the extent such
assets are attributable to Your Purchase Payments, it is not chargeable with
liabilities arising out of any other business that We may conduct. You do not
share in the investment performance of assets allocated to Separate Account MGA.
Income, gains and losses, whether or not realized, from assets allocated to
Separate Account MGA shall be charged against Separate Account MGA without
regard to Our other income, gains or losses. The obligations under this Contract
are independent of the investment performance of Separate Account MGA and are
Our obligations.

We will maintain assets with an aggregate market value at least equal to the
greatest of:

     (i)    an amount equal to the aggregate Cash Surrender Values of the
            Contracts funded by Separate Account MGA (as adjusted by the Market-
            Value Adjustment formula)

     (ii)   an amount equal to the reserves of the Contracts funded by Separate
            Account MGA

     (iii)   an amount of assets deemed by the qualified actuary to be
             sufficient to make good provision for the Contract liabilities.

If the aggregate market value of such assets in Separate Account MGA should fall
below such amount, We will establish a liability payable to Separate Account MGA
so that the aggregate market value for Separate Account MGA's assets is at least
equal to such amount.

SEPARATE ACCOUNT MGA II

Please note that since December 7, 2007, no Purchase Payments that have been
made to the Contract have been invested in Separate Account MGA II. Thus, the
following information pertains to Contracts that had Purchase Payments invested
in Separate Account MGA II prior to this date.

Purchase Payments made to this Contract are invested in Separate Account MGA II.
We have exclusive and absolute ownership and control of the assets of Separate
Account MGA II. It is a non-unitized Separate Account and is not chargeable with
liabilities arising out of any other business that We may conduct. You do not
share in the investment performance of assets allocated to Separate Account MGA
II. Income, gains and losses, whether or not realized, from assets allocated to
Separate Account MGA II shall be charged against Separate Account MGA II without
regard to Our other income, gains, or losses. The obligations under the Contract
are independent of the investment performance of Separate Account MGA II and are
Our obligations.



We will maintain in Separate Account MGA II assets with an aggregate market
value at least equal to the greatest of:

     (i)    an amount equal to the aggregate Cash Surrender Values of the
            Contracts funded by Separate Account MGA II (as adjusted by the
            Market-Value Adjustment formula)

     (ii)   an amount equal to the reserves of the Contracts funded by Separate
            Account MGA II

     (iii)   an amount of assets deemed by the qualified actuary to be
             sufficient to make good provision for the Contract liabilities.

If the aggregate market value of such assets should fall below such amount, We
will transfer assets into Separate Account MGA II so that the market value for
Separate Account MGA II's assets is at least equal to such amount.

3. Delete and replace the fourth sentence in the first paragraph in the section
entitled "INVESTMENTS BY THE COMPANY" on page 16 with the following:

MetLife of CT Separate Account MGA is a non-unitized Separate Account and to the
extent such assets are attributable to Your Purchase Payments amounts invested
in MetLife of CT Separate Account MGA are not chargeable with liabilities
arising out of any other business that the Company may conduct. MetLife of CT
