SUPPLEMENT TO PROSPECTUS DATED DECEMBER 10, 1999
***
Under DESCRIPTION OF THE CONTRACT, D. Choosing an Income Option, the second
paragraph is hereby replaced by the following:
If you select a Fixed Income Option, you must then choose between either the
Level Fixed Income Option or the Increasing Fixed Income Option (the Increasing
Fixed Income Option may not be available in all states). Any portion of the Net
Payment allocated to either Fixed Income Option will become part of our General
Account.
The Level Fixed Income Option provides that each monthly annuity payment will be
equal to the first (unless a withdrawal is made or as a result of the death of
the first Joint Annuitant). The Increasing Fixed Income Option provides level
annuity payments that increase on each anniversary of the Annuity Income Date.
On such date, the dollar amount of the monthly annuity payment under the
Increasing Fixed Income Option will increase by an amount equal to (a)
multiplied by (b) where:
(a) is the dollar amount of the previous annuity payment received
under the Increasing Fixed Income Option, proportionately reduced
by subsequent withdrawals and/or adjusted as a result of the
death of the first Joint Annuitant (see H. Withdrawals) and
(b) is the Guaranteed Annual Increase Adjustment (you select from the
adjustments offered by the Company at the time of purchase,
subject to state availability).
