withdrawal benefit for the life of the Annuitant(s) as described below. In
order to obtain the full benefit described in this rider, your annual

prescribed Investment Strategy. You may not terminate this rider apart from the
Contract.

All rider terms will have the same meaning as under the Contract, unless
otherwise provided.

Asset Allocation Model - The Asset Allocation Model shown on the Contract Data

     (1) the Contract Date; and

     (2) the Valuation Day of the most recent reset of the Withdrawal Base.

Investment Strategy

To maximize the Withdrawal Limit and Rider Death Benefit, you must allocate all
Contract Value to the Investment Strategy. We or our affiliates will provide
the Investment Strategy. You must allocate your Contract Value among the
following Investment Strategy options shown on the Contract Data Pages:

      .   the Designated Subaccounts; and/or

      .   the Asset Allocation Model.

                                      1

<PAGE>

You must allocate all Contract Value between the Investment Strategy options.
If you use the Designated Subaccounts option, you must specify the percentage
to invest in each Designated Subaccount. Under the Asset Allocation Model
option, any percentage of Contract Value invested must first be divided into
categories in accordance with the percentages shown on the Contract Data Pages.
Within each category you must then specify the percentage to invest in each
available Subaccount.

On a monthly basis, we will rebalance Contract Value to the Subaccounts in
accordance with the percentages that you have chosen. In addition, on any
Valuation Day after any transaction involving a withdrawal, receipt of a
Purchase Payment or a transfer of Contract Value, we will rebalance Contract
Value to the Subaccounts in accordance with the percentages that you have
chosen, unless you instruct us otherwise.

Beginning on the first Valuation Day after you choose not to follow the
Investment Strategy, your Withdrawal Factor and Rider Death Benefit will be
reduced as follows:

The Withdrawal Factor will be (a) minus (b), where:

     (a) is the Withdrawal Factor; and

     (b) is the Withdrawal Factor multiplied by the Withdrawal Factor Reduction
         Percentage.

The Rider Death Benefit will be (a) minus (b), where:

     (a) is the Rider Death Benefit; and

     (b) is the Rider Death Benefit multiplied by the Death Benefit Reduction
         Percentage.

You may elect to resume participation in the Investment Strategy, as described
in the Restoration or Reset of the Benefit provision, provided we receive
notice of your election in a form acceptable to us.

We will not reduce your Withdrawal Factor or Rider Death Benefit if you are not
following the Investment Strategy due to a portfolio liquidation or a portfolio
dissolution and the assets are transferred from the liquidated or dissolved
portfolio to another portfolio.

If this rider is added to the Contract at issue, the Guarantee Account
available as an Investment Option under the Contract, if any, will not be
available as an Investment Option under this rider for as long as this rider is
in effect.

Guaranteed Minimum Withdrawal Benefit

If you:

      .   allocate all Contract Value to the Investment Strategy; and

      .   limit total Gross Withdrawals in a Benefit Year to an amount no
          greater than the Withdrawal Limit;

then you will be eligible to receive total Gross Withdrawals in each Benefit
Year equal to the Withdrawal Limit until the last death of an Annuitant.

The Withdrawal Limit is calculated on each Valuation Day. The Withdrawal Limit
is (a) multiplied by (b), where:

     (a) is the greater of the Contract Value on the prior Contract anniversary
         and the Withdrawal Base; and

     (b) is the Withdrawal Factor.

                                      2

<PAGE>

The Withdrawal Factor is established based on the attained age of the younger
Annuitant on the earlier of the Valuation Day of the first Gross Withdrawal and
the Valuation Day when the Contract Value is reduced to zero. The Withdrawal
Factor percentage is shown on the Contract Data Pages.

Purchase Payments

Any Purchase Payment applied to your Contract will adjust your Withdrawal Base
and Rider Death Benefit. In order to obtain the full benefit provided by this
rider, you must allocate all assets to the prescribed Investment Strategy from
the Benefit Date. If you have allocated all assets to the Investment Strategy
since the Benefit Date, any subsequent Purchase Payment will be added to the
Withdrawal Base and the Rider Death Beneft. Otherwise, the Purchase Payment
will be added to the Withdrawal Base, and the Rider Death Benefit will be
increased by (a) minus (b), where:

     (a) is the Purchase Payment; and

     (b) is the Purchase Payment multiplied by the Death Benefit Reduction
         Percentage.

We reserve the right to not adjust the Withdrawal Base and/or the Rider Death
Benefit for any additional Purchase Payments.

Restoration or Reset of the Benefit

Restoration: If your Withdrawal Factor and Rider Death Benefit have been
reduced because you have not allocated all assets to the prescribed Investment
Strategy, you will have a one-time opportunity to restore your Withdrawal
Factor and Rider Death Benefit.

Reset: If all of the Annuitants are ages [50 through 59], you may choose to
reset your Withdrawal Base on [an annual] anniversary of the Contract Date that
is at least [12 months] after the later of (a) and (b). If the older of the
Annuitants is age [60 through the maximum reset age], you may choose to reset
your Withdrawal Base on [an annual] anniversary of the Contract Date that is at
least [36 months] after the later of (a) and (b), where:

     (a) is the Contract Date; and

     (b) is the last reset date.

If you do reset your Withdrawal Base, as of that date, we will:

      .   reset the Withdrawal Base to your Contract Value;

      .   reset the charge for this rider. The new charge, which may be higher
          than your previous charge, will never exceed [2.00%] annually; and

      .   reset the Investment Strategy to the current Investment Strategy.

There are similarities as well as distinct differences between restoring your
Withdrawal Factor and resetting your Withdrawal Base and Withdrawal Factor. The
similarities and differences are:

For either a restoration of your Withdrawal Factor, or a reset of your
Withdrawal Base, we must receive notice of your election in a form acceptable
to us at least [15] days prior to your next Contract anniversary. You may
restore your Withdrawal Factor and Rider Death Benefit once during the life of
this rider.

You may not use the restore or reset provision if any Annuitant is older than
age [85] on the Contract anniversary. We reserve the right to limit the
restoration date to a Contract anniversary on or after [three] complete year[s]
from the Benefit Date.

Withdrawals

If a Gross Withdrawal plus all prior Gross Withdrawals in a Benefit Year is in
excess of the Withdrawal Limit, your Withdrawal Base and Rider Death Benefit
are reduced. The new Withdrawal Base equals the lesser of (a) and (b), where:

     (a) is the Contract Value on the Valuation Day after the Gross Withdrawal;
         and

     (b) is the prior Withdrawal Base minus the Gross Withdrawal.

The new Rider Death Benefit equals the lesser of (a) and (b), where:

     (a) is the Contract Value on the Valuation Day after the Gross Withdrawal;
         and

     (b) is the prior Rider Death Benefit minus the Gross Withdrawal.

If the total Gross Withdrawals in a Benefit Year are less than or equal to the
Withdrawal Limit, we will waive any surrender charge on the Gross Withdrawals.

Required Minimum Distributions

If all Contract Value is allocated to the Investment Strategy, the Withdrawal
Limit will be increased for any Benefit Year to the extent necessary to meet
any minimum distribution requirements under federal tax law. This increase
applies only to the required minimum distribution based on the value of the
Contract.

Reduction in Contract Value

Your Contract Value after taking a withdrawal may be less than the amount
required to keep your Contract in effect. In this event or if your Contract
Value becomes zero, your Contract, this rider and any other riders and
endorsements will terminate and the following will occur:

      .   If the Withdrawal Limit is less than $100, we will pay you the
          greatest of the Rider Death Benefit, Contract Value and the present
          value of the Withdrawal Limit in a lump sum calculated using the
          Annuity 2000 Mortality Table and an interest rate of 3%.

                                      4

<PAGE>

      .   If the Withdrawal Limit is greater than $100, we will issue you a
          supplemental contract. We will continue to pay you the Withdrawal
          Limit until the last death of an Annuitant. We will make payments
          monthly unless agreed otherwise. If the monthly amount is less than
          $100, we will reduce the frequency so that the payment will be at
          least $100. The Rider Death Benefit will continue under the
          supplemental contract. The Rider Death Benefit will be reduced by
          each payment made under the supplemental contract. The Rider Death
          Benefit, if any, will be payable on the last death of an Annuitant.

Rider Death Benefit

The Rider Death Benefit on the Contract Date is equal to the initial Purchase
Payment.

Purchase Payments in a Benefit Year increase the Rider Death Benefit. If you
have allocated all assets to the Investment Strategy since the Benefit Date,
any subsequent Purchase Payment will be added to the Rider Death Benefit.
Otherwise, the Rider Death Benefit will be increased by (a) minus (b), where:

     (a) is the Purchase Payment; and

     (b) is the Purchase Payment multiplied by the Death Benefit Reduction
         Percentage.

Gross Withdrawals in a Benefit Year decrease the Rider Death Benefit. If a
Gross Withdrawal plus all prior Gross Withdrawals in a Benefit Year is less
than or equal to the Withdrawal Limit, the Rider Death Benefit will be reduced
by the Gross Withdrawal. If a Gross Withdrawal plus all prior Gross Withdrawals
in a Benefit Year is in excess of the Withdrawal Limit, your Rider Death
Benefit will equal the lesser of (a) and (b), where:

     (a) is the Contract Value on the Valuation Day after the Gross Withdrawal;
         and

     (b) is the prior Rider Death Benefit minus the Gross Withdrawal.

If you choose not to follow the Investment Strategy, your Rider Death Benefit
will be reduced as described in the Investment Strategy provision.

Death Provisions

At the death of the last Annuitant, a Death Benefit may be payable under this
Contract and rider. The amount of any Death Benefit payable will be the
greatest of (a), (b) and (c), where:

     (a) is the Death Benefit as calculated under the base Contract;

     (b) is the Rider Death Benefit; and

     (c) is any amount payable by any other optional death benefit rider.

The Death Benefit payable will be paid according to the distribution rules
under the Contract.

If the designated beneficiary is a surviving spouse who is not an Annuitant,
whose age is [50] through [85], and who elects to continue the Contract as the
new Owner, this rider will continue. The Withdrawal Base for the new Owner will
be the Death Benefit determined as of the first Valuation Day we have receipt
of due proof of death and all required forms at our [Home Office]. The
Withdrawal Factor for the new Owner will be based on the age of that Owner on
the date of the first Gross Withdrawal for that Owner.

If the designated beneficiary is a surviving spouse who is an Annuitant and who
elects to continue the Contract as the Owner, this rider will continue. The
Withdrawal Base will be the same as it was under the Contract for the deceased
Owner. If no withdrawals were taken prior to the first Valuation Day we receive
due proof of death and all required forms at our Home Office, the Withdrawal
Factor

                                      5

<PAGE>

for the surviving spouse will be established based on the attained age of the
surviving spouse on the date of the first Gross Withdrawal for the surviving
spouse. Otherwise, the Withdrawal Factor will continue as it was under the
Contract for the deceased Owner.

If the surviving spouse cannot continue the rider, the rider and the rider
charge will terminate on the next Contract anniversary.

Rider Charge

There will be a daily asset charge for this rider. This charge is added to the
Contract's daily asset charge and applied against all amounts allocated to the
Subaccounts. The charge for this rider will depend upon whether the Contract is
a single Annuitant or Joint Annuitant Contract. This charge is shown on the
Contract Data Pages. Once applied, the Joint Annuitant charge will continue
while the rider is in effect. The charge for this rider will be reset if you
choose to reset your Withdrawal Base and Rider Death Benefit. The new charge,
which may be higher than your previous charge, will never exceed [2.00%]
annually.

When this Rider is Effective

The rider becomes effective on the Contract Date. It will remain in effect
while this Contract is in force and before the Annuity Commencement Date. This
rider may not be terminated prior to the Annuity Commencement Date. On the
Annuity Commencement Date, this rider will terminate.

Change of Ownership

We must approve any assignment or sale of this Contract unless under a court
ordered assignment.

      .   A non-natural entity Owner must name an Annuitant and may name the
          Annuitant's spouse as a Joint Annuitant.
