The Guaranteed  Maturity  Annuity being offered  pursuant to this Prospectus has
the following charges and features:

Sales  Charge/Surrender  Charge:  A sales  charge is  assessed  when  premium is
submitted.  The  amount of the sales  charge  depends  on the  amount of premium
submitted  at the time,  irrespective  of the number of  Contracts  issued  (see
"Application  and Premium  Payment",  p. 9). The sales charge is as shown in the
chart below.  There is no surrender charge on either a full or partial surrender
(see "Sales Charge", p. 9and "Surrender Charge", p. 13).

Breakpoints:  While we reserve the right to make additions to the Interim Values
of Contracts of Participants  submitting large amounts of premium,  we currently
do not make such  additions  in relation  to large  premiums  submitted  for the
Guaranteed  Maturity  Annuity being offered to you pursuant to this  Prospectus.
However,  the sales charges noted below do decrease as shown for larger premiums
(see "Breakpoints", p. 18).
