Endorsement - [L-Share] Enhanced Death Benefit Rider

As used in this Endorsement, "Contract" means the Contract or Certificate to
which this Endorsement is attached. This Endorsement forms a part of the
Contract to which it is attached. The election of this Rider and the Rider
charge are stated on the Contract Schedule.

The Amount Payable Upon Death provision of the Contract to which this
Endorsement is attached is deleted in its entirety and replaced with the
following:

Class 1 Accumulation Options

Certain Accumulation Options may be considered Class 1 Accumulation Options. The
list of Class 1 Accumulation Options, if any, is shown on the Contract Schedule.
Class 1 Accumulation Options may be subject to limitations or rules when
calculating the death benefit described below.

We may reduce the Rider charge for the portion of Contract Value allocated to
Class 1 Accumulation Options. We may add or remove Accumulation Options to the
Class 1 Accumulation Options. We will give You 30 days notice of any changes.
Such changes will apply to transfers and subsequent Purchase Payments allocated
to the Class 1 Accumulation Options after the date of any change.

The death benefit payable under this Rider is equal to the greatest of the
following less debt:

     (1)  the Contract Value, excluding any negative Market Value Adjustment but
          including any positive Market Value Adjustment, and

     (2)  the total amount of Purchase Payments, less previous Purchase Payments
          withdrawn and withdrawal charges, and

     (3)  the Step-up Death Benefit.

We compute the Contract Value at the end of the Valuation Period following our
receipt of due proof of death and the return of the Contract. We compute the
other amounts above as of the date of death.

Step-Up Death Benefit

The Step-up Death Benefit for the Contract is equal to the sum of (i+ii):

     i)   the greater of:

          a)   Contract Value allocated to the Class 1 Accumulation Options, or

          b)   Adjusted Purchase Payment Death Benefit for Class 1 Accumulation
               Options, and

     ii)  Guaranteed Step-up Death Benefit for Class 2 Accumulation Options.

The Adjusted Purchase Payment Death Benefit for Class 1 Accumulation Options on
the Issue Date is equal to the initial Purchase Payment allocated to the Class 1
Accumulation Options. On a subsequent Valuation Date, the Adjusted Purchase
Payment Death Benefit for Class 1 Accumulation Options is adjusted by adding to
the prior value:

     (1)  any subsequent Purchase Payments allocated to the Class 1 Accumulation
          Options, and

     (2)  any adjustments for transfers to the Class 1 Accumulation Options.
and subtracting:

     (3)  any adjustments for transfers from the Class 1 Accumulation Options,
          and

     (4)  the amount of any pro rata adjustment for withdrawals from the Class 1
          Accumulation Options.

The Guaranteed Step-up Death Benefit for Class 2 Accumulation Options on the
Issue Date is equal to the initial Purchase Payment allocated to the Class 2
Accumulation Options. On each subsequent Contract Anniversary, prior to the
oldest Owner attaining age [81,]the Guaranteed Step-up Death Benefit for Class
2 Accumulation Options equals the greater of (1) and (2) below. On all other
Valuation Dates the Guaranteed Step-up Death Benefit for Class 2 Accumulation
Options is equal to (2) below.

     (1)  Contract Value allocated to the Class 2 Accumulation Options, or

     (2)  the Guaranteed Step-up Death Benefit for Class 2 Accumulation Options
          on the prior Contract Anniversary plus:

          a)   any Purchase Payments allocated to the Class 2 Accumulation
               Options since the prior Contract Anniversary, and

          b)   any adjustments for transfers from the Class 1 Accumulation
               Options made since the prior Contract Anniversary, and

               less:

          c)   any adjustments for transfers to the Class 1 Accumulation Options
               made since the prior Contract Anniversary, and

          d)   the amount of any pro rata adjustment for withdrawals from the
               Class 2 Accumulation Options since the prior Contract
               Anniversary.

Adjustments for Transfer and Withdrawals

Transfers from Class 1 Accumulation Options to Class 2 Accumulation Options will
reduce the Adjusted Purchase Payment Death Benefit for Class 1 Accumulation
Options on a pro rata basis. The resulting increase in the Guaranteed Step-up
Death Benefit for the Class 2 Accumulation Options is equal to the lesser of:

     (1)  the reduction in Adjusted Purchase Payment Death Benefit for Class 1
          Accumulation Options, and

     (2)  net Contract Value transferred.

Transfers from Class 2 Accumulation Options to Class 1 Accumulation Options will
reduce the Guaranteed Step-up Death Benefit for the Class 2 Accumulation Options
on a pro rata basis. The resulting increase in the Adjusted Purchase Payment
Death Benefit for Class 1 Accumulation Options is equal to reduction in the
Guaranteed Step-up Death Benefit for the Class 2 Accumulation Options.

Pro rata adjustment - The pro rata adjustment applies to transfers and partial
withdrawals from the Class 1 Accumulation Options and Class 2 Accumulation
Options.

     The pro rata adjustment for transfers and withdrawals from Class 1
     Accumulation Options is equal to (1) divided by (2), with the result
     multiplied by (3), where:

          (1)  is the withdrawal and withdrawal charge or transfer amount,

          (2)  is the Contract Value allocated to the Class 1 Accumulation
               Options immediately prior to the withdrawal or transfer,

          (3)  is the value of the applicable death benefit immediately prior to
               the withdrawal or transfer.

     The pro rata adjustment for transfers and withdrawals from Class 2
     Accumulation Options is equal to (1) divided by (2), with the result
     multiplied by (3), where:

          (1)  is the withdrawal and withdrawal charge or transfer amount,

          (2)  is the Contract Value allocated to the Class 2 Accumulation
               Options immediately prior to the withdrawal or transfer,

          (3)  is the value of the applicable death benefit immediately prior to
               the withdrawal or transfer.
