PROSPECTUS DATED JULY 1, 1999
- -----------------------------------------------------------------
The following two paragraphs are added to the end of the section
of the prospectus entitled "Sales of the Certificates". These
paragraphs relate to our exchange programs for fixed annuity and
variable annuity contracts ("Old VA") we previously issued.
Under any exchange program of ours, we treat the exchange as
being income-tax free. Before making any exchange, you should
consult a competent tax adviser and, for Old VA to Certificate
exchanges, you also should consider the differences between the
two variable annuities, including the Sub-account selections.
You may make an exchange to a Certificate if we are making
variable annuity payments for a fixed number of years under an
Old VA. Under your Certificate, the Income Date will be the date
of the next scheduled payment under the Old VA and the payment
period will be the payment period remaining under the Old VA. On
the Certificate Date of your new Certificate, the present value
of the remaining annuity payments under the Old VA will be
allocated to the Sub-account(s) you select under the Certificate
and the amount of future variable annuity payments under your
Certificate will be based upon the investment return of those Sub-
account(s). From the Certificate Date to the Income Date, we will
treat your Certificate as one under which periodic annuity
payments have begun, and not one that has values based on
Accumulation Units. Other than the change in Sub-account
allocation described above, we do not permit you to make any
changes as you exchange from the Old VA to your Certificate.
