                       MAXIMUM ANNIVERSARY VALUE OPTIONAL
                            DEATH BENEFIT ENDORSEMENT

This Endorsement is made a part of, and subject to, the other terms and
conditions of the Contract to which it is attached.

This Endorsement modifies the AMOUNT OF DEATH BENEFIT under the DEATH OF OWNER
BEFORE THE ANNUITY DATE in the Contract.

The following are added under the DEFINITIONS section of the Contract:

         NET PURCHASE PAYMENT
         The sum of all Purchase Payments, reduced proportionately on the date
         of each partial withdrawal by the percentage at which the Contract
         Value is reduced by such withdrawal (including any charges applicable
         to the withdrawal).

AMOUNT OF DEATH BENEFIT
If, upon the death of the Owner and prior to the Annuity Date, the Owner has not
attained age 90, the amount of the Death Benefit will be as described under the
Maximum Anniversary Value Optional Death Benefit. If the deceased Owner has
attained age 90, then the Death Benefit will be the Contract Value. This Death
Benefit option cannot be changed or terminated.

MAXIMUM ANNIVERSARY VALUE OPTIONAL DEATH BENEFIT
As of the date We receive Your Due Proof of Death and prior to the Owner
attaining age 90, the Death Benefit will be the greatest of:

(a)  Net Purchase Payments; or

(b)  Contract Value; or

(c)  The Maximum Anniversary Value.

We will calculate the Maximum Anniversary Value, by determining the Contract
Value for each Contract anniversary prior to the Owner's 81st birthday. An
anniversary value is equal to the Contract Value at a Contract anniversary
increased by the dollar amount of any Purchase Payment(s) made since that
anniversary and reduced for any partial withdrawals since that anniversary (and
any charges applicable to such withdrawals) in the same proportion that the
Contract Value was reduced on the date of such withdrawal. If any of those
anniversary values is greater than Your Contract Value, You will receive that
amount as the Maximum Anniversary Value.

MAXIMUM ANNIVERSARY OPTIONAL DEATH BENEFIT CHARGE
On an annual basis, this charge equals [0.15%] of Your average daily ending
value of the assets attributable to the Accumulation Units of the Subaccount(s)
to which the Contract is allocated. We deduct this charge daily. This charge is
in addition to the charges in Your Contract.

                          PURCHASE PAYMENT ACCUMULATION
                       OPTIONAL DEATH BENEFIT ENDORSEMENT

This Endorsement is made a part of, and subject to, the other terms and
conditions of the Contract to which it is attached.

This Endorsement modifies the AMOUNT OF DEATH BENEFIT under the DEATH OF OWNER
BEFORE THE ANNUITY DATE in the Contract.

PURCHASE PAYMENT ACCUMULATION OPTIONAL DEATH BENEFIT CHARGE On an annualized
basis, this charge equals [0.20%] of Your average daily ending value of the
assets attributable to the Accumulation Units of the Subaccount(s) to which the
Contract is allocated. We deduct this charge daily. This charge is in addition
to the charges in Your Contract.

PURCHASE PAYMENT ACCUMULATION OPTIONAL DEATH BENEFIT As of the date We receive
Your Due Proof of Death, the Death Benefit will be the greatest of:

(a)  The Contract Value; or

(b)  Purchase Payment(s) reduced for any partial withdrawals (and any charges
     applicable to such withdrawals), in the same proportion that the Contract
     Value was reduced on the date of such withdrawal, compounded at [4%]
     interest to date of death, plus any Purchase Payment(s) recorded after the
     date of death; and reduced for any partial withdrawals (and any charges
     applicable to such withdrawals) in the same proportion that the Contract
     Value was reduced on the date of such withdrawal recorded after the date of
     Death; or

(c)  The Contract Value at the seventh Contract anniversary, plus any subsequent
     Purchase Payments, reduced for any subsequent withdrawals (and any charges
     applicable to such withdrawals) in the same proportion that the Contract
     Value was reduced on the date of such withdrawal, compounded until the date
     of death at [4%] interest, plus any Purchase Payments recorded after the
     date of death; and reduced for any withdrawals (and any charges applicable
     to such withdrawals) in the same proportion that the Contract Value was
     reduced on the date of such withdrawal recorded after date of death.

If the Owner was age 70 or older on the Contract Date, both (b) and (c) above
will be compounded at 3%, rather than 4%. If the death benefit is paid on the
death of an Owner who was not originally named in the application and was age 70
or older on the Contract Date, both (b) and (c) above will be compounded at 3%,
rather than 4%.

Once elected, this Purchase Payment Accumulation Optional Death Benefit cannot
be changed or terminated.

                       OPTIONAL DEATH BENEFIT ENHANCEMENT

This Endorsement is made a part of, and subject to, the other terms and
conditions of the Contract to which it is attached.

This Endorsement modifies the AMOUNT OF DEATH BENEFIT before the Annuity Date
under the DEATH PROVISIONS and is effective on the Contract Date.

The following terms in this Endorsement are defined as follows:

     CONTINUATION DATE is the Date on which We receive, in Our Service Center
     both: (a) the Spousal Beneficiary's written request to continue the
     Contract in force, and (b) Due Proof of Death of the Contract Owner. If We
     receive (a) and (b) on different dates, the Continuation Date will be the
     later date.

     CONTINUATION YEAR is a year starting from the Continuation Date in one
     calendar year and ending on the day preceding the anniversary of such date
     in the succeeding calendar year.

     NET PURCHASE PAYMENT is the sum of all [Gross] Purchase Payments, reduced
     proportionately on the date of each partial withdrawal by the percentage at
     which the Contract Value is reduced by such withdrawal (including any fees
     or charges applicable to the withdrawal).

     SPOUSAL BENEFICIARY is the Owner's spouse who: (a) is designated as the
     primary Beneficiary; (b) is age 80 or younger at the time of the Owner's
     death; and (c) elects to continue the Contract as the Owner.

                      DEATH BENEFIT ENHANCEMENT PROVISIONS

The Death Benefit Enhancement is an amount, calculated using the Death Benefit
Enhancement table below that may be payable in addition to the Death Benefit
option You selected. Once elected, You cannot terminate this Death Benefit
Enhancement. However, Your Spousal Beneficiary can terminate this benefit on the
Continuation Date. The Death Benefit Enhancement terminates upon the Latest
Annuity Date.

DEATH BENEFIT ENHANCEMENT BEFORE THE CONTINUATION DATE
Earnings, for purposes of calculating the Death Benefit Enhancement amount,
equal the amount by which Your Contract Value exceeds Net Purchase Payment(s) as
of the date of Your death. If You have earnings as defined above in Your
Contract at the time We receive Your Due Proof of Death, We will add any
applicable Death Benefit Enhancement to the amount of Your Death Benefit. The
Percentage of Earnings that will be added to Your Death Benefit as a Death
Benefit Enhancement depends on how long Your Contract was in force prior to the
date of Your death.

For purposes of determining any Death Benefit Enhancement amount payable upon
Your death, the items in the Death Benefit Enhancement table are described as
follows:

     NUMBER OF YEARS ELAPSED is the number of full Contract Years from the
     Contract Date to the date of Your death.

     PERCENTAGE OF EARNINGS is a percentage applied to the earnings in Your
     Contract from the Contract Date to the date of Your death.

     MAXIMUM BENEFIT PERCENTAGE is a percentage that when applied to the Net
     Purchase Payment(s) defines the maximum amount of the Death Benefit
     Enhancement. Net Purchase Payments received by Us after the [0-10th]
     Contract Anniversary, must remain in Your Contract for at least [0-12 full
     months] to be included in the calculation of the maximum amount of the
     Death Benefit Enhancement.

DEATH BENEFIT ENHANCEMENT AFTER THE CONTINUATION DATE
Upon receipt of Due Proof of Death of the Spousal Beneficiary, We will add any
applicable Death Benefit Enhancement to the amount of the Spousal Beneficiary's
Death Benefit.

For purposes of determining any Death Benefit Enhancement amount payable upon
the Spousal Beneficiary's death, the following items in the Death Benefit
Enhancement table are described as follows:

     NUMBER OF YEARS ELAPSED is the number of full Continuation Years from the
     Continuation Date to the date of death of the Spousal Beneficiary.

     PERCENTAGE OF EARNINGS is a percentage applied to the earnings in the
     Contract from the Continuation Date to the Spousal Beneficiary's date of
     death. For purposes of this calculation, earnings are defined as (a) minus
     (b) where:
          (a)  is the Contract Value on the Spousal Beneficiary's date of death;
               and
          (b)  is the sum of the Contract Value on the Continuation Date
               (including any amount added to the Contract Value by Us) and any
               Net Purchase Payment(s) received on or after the Continuation
               Date.

     MAXIMUM BENEFIT PERCENTAGE is a percentage, that when applied to the sum of
     (a) plus (b) below, defines the maximum amount of the Death Benefit
     Enhancement, where:

          (a)  is the Contract Value on the Continuation Date (including any
               amount added to the Contract Value by Us on the Continuation
               Date), reduced proportionately on the date of each partial
               withdrawal occurring on or after the Continuation Date, by the
               percentage at which the Contract Value is reduced by such
               withdrawal (including any fees or charges applicable to the
               withdrawal) on that date;
          (b)  is any Net Purchase Payment(s) made on or after the Continuation
               Date until the Spousal Beneficiary's date of death. Purchase
               Payments received by Us after [0-10] Continuation Years, must
               remain in Your Contract for at least [0-12 full months] to be
               included in the calculation of the maximum amount of the Death
               Benefit Enhancement.
