amended
You may instruct us to allocate all or part of your
premium payments to the Focused 30 and Strategic Value

these Investment Options prior to October 2, 2000, when

Transfers of This information is added to the discussion in the
Accumulated Value Prospectus on Transfers of Accumulated Value.
is amended
You may instruct us to transfer Accumulated Value to a
Variable Investment Option and specify a future date on
which the Accumulated Value is to be transferred. This
instruction may cover any Variable Investment Option
currently available under your contract and the Focused
30 and Strategic Value Investment Options. For the
Focused 30 and Strategic Value Investment Options, you
may not specify a date prior to October 2, 2000, when
the Options first become available. If you specify
October 2, 2000 for the Focused 30 and Strategic Value
Investment Options, and we receive the instructions
prior to that date, the requested amount will be
transferred effective as of the close of business on
October 2, 2000. You may revoke your transfer
instructions at any time before we transfer Accumulated
Value by providing us with a revocation in proper form,
which we must receive not later than 4:00 p.m. Eastern
time on the last Business Day before the date you have
specified for a transfer. While highly remote, there is
a possibility that the Focused 30 and Strategic Value
Investment Options will not become effective on October
2, 2000, in which case we would not effect the transfer
to these Options, and your Accumulated Value would
remain in the Investment Option from which you
requested it be transferred until the day the Focused
30 and Strategic Value Portfolios become effective, if
ever, unless you instruct us otherwise.
