                      AIG SUNAMERICA LIFE ASSURANCE COMPANY

                         PAYMENT ENHANCEMENT ENDORSEMENT

Notwithstanding any provision in the Contract or Certificate ("Contract") to the
contrary, this Payment Enhancement Endorsement (the "Endorsement") becomes a
part of the Contract to which it is attached. Should any provision in this
Endorsement conflict with the Contract, the provisions of this Endorsement will
prevail.

Subject to the terms and conditions set forth below, this Endorsement credits
additional amounts to Your Contract Value based on certain Purchase Payment(s)
made to Your Contract prior to Age [86]. The expenses for this annuity may be
higher than the expenses for an annuity without Payment Enhancements. This
Endorsement may not be elected with other Endorsements containing different
Withdrawal Charges or Schedules.

                                   DEFINITIONS

For purposes of this Endorsement, the following definitions apply. Terms not
defined in this Endorsement shall have the same meaning given to them in the
Contract.

PAYMENT ENHANCEMENT
Amounts allocated to Your Contract Value by Us. Payment Enhancements are not
considered Purchase Payments.

PAYMENT ENHANCEMENT RATE
The percentage applied to each Purchase Payment to calculate the Payment
Enhancement.

                         PAYMENT ENHANCEMENT PROVISIONS

ALLOCATION OF PAYMENT ENHANCEMENTS
We will allocate Payment Enhancements to available Variable Portfolio(s) and/or
Fixed Account Option(s) in the same proportion as each corresponding Purchase
Payment.

Payment Enhancements for Subsequent Purchase Payment(s) will be determined by
the Payment Enhancement Rate in effect at the time Your Subsequent Purchase
Payment is received by Us. We will send You a confirmation of the Payment
Enhancement allocated to Your Contract Value.

DURING THE RIGHT TO EXAMINE/RIGHT TO CANCEL PERIOD
If You cancel Your Contract and this Endorsement and if Your Contract requires:

         1.   The return of Contract Value, We will refund the Contract Value as
              of the business day during which the Contract is received by Us
              reduced by the lesser of: (a) the value of all Payment
              Enhancements as of the date on which We receive Your request to
              cancel Your Contract; or (b) the amount of all Payment
              Enhancements We allocated to Your Contract Value; or

         2.   The return of Purchase Payment(s), We will refund the Purchase
              Payment(s).

We reserve the right to allocate Your Payment Enhancement(s) to a Variable
Portfolio with a cash management objective until the end of the Right To
Examine/Right To Cancel period.
