</TABLE>

BENEFIT BASE EVALUATION PERIOD
A Benefit Base Evaluation Period begins on the Effective Date and extends to the
10th Benefit Year anniversary.

CALCULATION OF THE COMPONENTS OF THE GMWB
The GMWB is available for Withdrawal at any time while the Rider is in effect
and prior to any termination of the GMWB. The amount of Withdrawals and time
period over which You can take Withdrawals under the GMWB may change over time
as a result of Withdrawal activity or Benefit Base increase. Withdrawals made
under this Rider are treated like any other Withdrawal under the Contract for
purposes of calculating Contract Value, Withdrawal Charges, and any other
benefits under the Contract. Withdrawals in excess of the Penalty Free
Withdrawal amount will be assessed a Withdrawal Charge, if applicable.

To determine the GMWB, We calculate each of the following components: Benefit
Base and MAWA. The calculations for each component are detailed below.

BENEFIT BASE
The initial Benefit Base is Eligible Purchase Payments multiplied by the
percentage as specified in the table below.

The table below identifies the Eligible Purchase Payments included in the
calculation of the Benefit Base, as determined by the time elapsed between the
Effective Date and the day on which Purchase Payments are received by Us and
deposited into Your Contract. Payment Enhancements, if applicable, are not
considered Eligible Purchase Payments.

           0-2 Years                                    [100%]
</TABLE>

On any Benefit Year anniversary occurring during the Benefit Base Evaluation
Period, the Benefit Base is automatically increased to the Anniversary Value
when the Anniversary Value is greater than (a) and (b), where:

        (a)   is the current Benefit Base; and

        (b)   is all previous Anniversary Values during any Benefit Base
              Evaluation Period.

The Benefit Base is not used in the calculation of Contract Value or any other
benefits under the Contract. We reserve the right to limit the Eligible Purchase
Payments to a maximum of $1,000,000.

MAXIMUM ANNUAL WITHDRAWAL AMOUNT ("MAWA")
The MAWA is an amount calculated as a percentage of the Benefit Base. The
applicable Maximum Annual Withdrawal Percentage ("MAWP") used to calculate the
MAWA is determined by when the first Withdrawal is made by You, as specified in
the table below.

</TABLE>

If You are taking required minimum distributions ("RMD") from the Contract, the
MAWA is the greater of the MAWA as described above or the annual RMD amount
applicable to the Contract Value only.

The MAWA can be withdrawn throughout each Benefit Year. If You do not withdraw
the entire MAWA in a Benefit Year, You will maintain Your Minimum Withdrawal
Period, but the MAWA will not increase. Excess Withdrawals in any Benefit Year
may reduce Your future MAWA. See IMPACT OF WITHDRAWALS section below.

If the Benefit Base is increased to the Anniversary Value, the MAWA will be
recalculated on that Benefit Year anniversary, by multiplying the new Benefit
Base by the applicable MAWP.

IMPACT OF WITHDRAWALS
Withdrawals reduce the amount available for Withdrawal under the GMWB. Total
Withdrawals in any Benefit Year equal to or less than the MAWA reduce the
Benefit Base by the amount of the Withdrawal. Once Withdrawals in a Benefit Year
exceed the MAWA, all subsequent Withdrawals in that Benefit Year are Excess
Withdrawals. Excess Withdrawals may reduce the Benefit Base based on the
relative size of the Withdrawal in relation to the Contract Value at the time of
the Excess Withdrawal. This means that when the Contract Value is less than the
Benefit Base, Excess Withdrawals will result in a reduction of the Benefit Base
which is greater than the amount of the Excess Withdrawal. We further explain
this impact and the effect on each component of the GMWB through the
calculations below:

WITHDRAWALS IMPACT CONTRACT VALUE AND THE COMPONENTS OF THE GMWB CALCULATION AS
FOLLOWS:

      1.  CONTRACT VALUE: Any Withdrawal reduces the Contract Value by the
          amount of the Withdrawal.

      2.  BENEFIT BASE: Withdrawals up to the MAWA, before any Excess
          Withdrawal, reduce the Benefit Base by the dollar amount of the
          Withdrawal.

          Any Excess Withdrawal further reduces the Benefit Base to the lesser
          of (a) or (b), where:

            (a)   is the Benefit Base immediately prior to the Excess Withdrawal
                  minus the amount of the Excess Withdrawal, or;

            (b)   is the Benefit Base immediately prior to the Excess Withdrawal
                  reduced in the same proportion by which the Contract Value is
                  reduced by the Excess Withdrawal.

      3.  MINIMUM WITHDRAWAL PERIOD: If the total of all Withdrawals in a
          Benefit Year are less than or equal to the MAWA, the new MWP equals
          the Benefit Base after the Withdrawal divided by the current MAWA.
          When the Benefit Base is adjusted to a higher Anniversary Value, a new
          MWP is determined by dividing the new Benefit Base by the new MAWA.

      If there is an Excess Withdrawal in a Benefit Year, the new MWP equals the
      MWP calculated at the end of the prior Benefit Year reduced by one year.

      4.  MAXIMUM ANNUAL WITHDRAWAL AMOUNT: If there are no Excess Withdrawals
          in a Benefit Year, the MAWA does not change for the next Benefit Year,
          unless the Benefit Base is increased as described above under "Benefit
          Base."

      If there are any Excess Withdrawals in a Benefit Year, the MAWA will be
      recalculated on the next Benefit Year anniversary. The new MAWA will equal
      the new Benefit Base on that Benefit Year anniversary after the



                                       3
<PAGE>

      Withdrawal divided by the new Minimum Withdrawal Period on that Benefit
      Year anniversary. The new MAWA may be lower than Your previously
      calculated MAWA.

IF YOUR CONTRACT VALUE IS REDUCED TO ZERO
If Your Contract Value is reduced to zero and the Benefit Base is greater than
zero, subsequent Purchase Payments will no longer be accepted and a Death
Benefit will not be payable. You can receive the remaining value of the GMWB
under one of the following options:

      a.  A lump sum equal to the discounted present value of any remaining
          guaranteed payments under the GMWB; or,

      b.  Periodic payments during each Benefit Year that in total are equal to
          the MAWA until the Benefit Base has been reduced to zero. If You do
          not select a specific frequency for these payments, We will pay the
          current MAWA in quarterly payments; or,

      c.  Any payment option that is mutually agreeable.

EXTENSION OF THE BENEFIT BASE EVALUATION PERIOD ("EXTENSION")
We may offer You at least one Extension of the Benefit Base Evaluation Period at
the end of the current Benefit Base Evaluation Period. If You elect such
Extension, you will receive a new Rider with the charges and provisions in
effect at that time.

TERMINATION OF THE GMWB
Once elected the GMWB Rider and its corresponding charge may be terminated by
the Owner. If the Owner's request to terminate the GMWB is received:

      1.  prior to the 5th Benefit Year anniversary, the termination is
          effective on the 5th Benefit Year anniversary;

      2.  after the 5th, but prior to the 10th Benefit Year anniversary, the
          termination is effective on the 10th Benefit Year anniversary;

      3.  in any Benefit Year after the 10th Benefit Year anniversary, the
          termination is effective on the Benefit Year anniversary following Our
          receipt of the election to terminate the GMWB.

The Rider and the related charge will terminate automatically if:

      1.  The Benefit Base has been reduced to zero; or,

      2.  A Spousal Beneficiary elects to continue the Contract without this
          Rider; or,

      3.  A Death Benefit is paid (as described under the Death Provisions or
          Death Benefit section of Your Contract); or,

      4.  The Contract is fully withdrawn or surrendered; or,

      5.  The Contract is annuitized.

We reserve the right to terminate the GMWB Rider if Withdrawals in excess of the
MAWA in any Benefit Year reduce the Benefit Base by 50% or more.

If terminated, the GWMB may not be re-elected.

SPOUSAL CONTINUATION
Upon election to continue the Contract and this Rider, Your Spousal Beneficiary
will be subject to the terms and conditions of this Rider. The Effective Date
will not change as the result of Spousal Continuation. A continuation
contribution paid under the Spousal Continuation provision of the Contract is
not considered an Eligible Purchase Payment, but is included in the calculation
of Anniversary Values if the spouse continues the Benefit Base Evaluation
Period.

Signed for the Company to be effective on the Effective Date.
