                         INDIVIDUAL RETIREMENT ANNUITY

                          PAYMENT CHOICE ENDORSEMENT

This endorsement amends the Contract to which it is attached by adding a
Definition to the DEFINITIONS section and an additional Payment Choice in the
[Distribution Rules When Death Occurs Before Income Payments Begin] under the
Death Provisions section. Any reference herein to Contract also means Policy.

DEFINITIONS

Inherited Owner--For purposes of this endorsement an Inherited Owner is any
Designated Beneficiary receiving death proceeds from the Contract or any
beneficiary receiving death proceeds from any other individual retirement plan.
A surviving spouse may elect to be treated as an Inherited Owner in lieu of
exercising spousal continuation. The Inherited Owner will be named the
Annuitant at election of the payment choice.

DEATH PROVISIONS

Payment Choices, in the [Distribution Rules When Death Occurs Before Income
Payments Begin], under the DEATH PROVISIONS section of the Contract is amended
by adding the following language:

    (4)Apply the death proceeds to provide for an annual payment equal to the
       Minimum Annual Income, described below. Payments will continue annually
       on the distribution date selected by the Inherited Owner, subject to
       Special Rules stated below until the death of the Inherited Owner or the
       Contract Value is reduced to $0. Upon death of the Inherited Owner, the
       person or entity named by the Inherited Owner or, if no one is named,
       the Inherited Owner's estate may receive the remaining Contract Value.
       The recipient may take the Contract Value as a lump sum or continue to
       receive the annual payment on the distribution date equal to the Minimum
       Annual Income until the Contract Value is reduced to $0.

       The Minimum Annual Income is the amount withdrawn each year to satisfy
       section 408(b)(3) of the Code. The Minimum Annual Income will be based
       on the applicable distribution period for required minimum distributions
       after death, as provided in section 1.401(a)(9)-5 A-5 of the Income Tax
       Regulations.

   Special Rules for this payment choice only:

    .  This payment choice cannot be selected if the Minimum Annual Income
       would be less than $100.

    .  The Inherited Owner must elect a distribution date on which payments
       will be made. If the Inherited Owner is the surviving spouse of the
       original IRA owner within the meaning of section 401(a)(9)(B)(iv) of the
       Code, then the first distribution date elected must be the later of
       either: (i) December 15/th/ of the year in which the deceased would have
       been age 70  1/2 or (ii) December 15/th/ of the year following the
       original IRA owner's death. If the Inherited Owner is not the surviving
       spouse of the original IRA owner, then the first distribution date
       elected must be within 350 days from the date of death. If the surviving
       spouse dies before the first distribution date, the first distribution
       date under this rider will be determined by treating death of the
       surviving spouse as death of the original IRA owner and the surviving
       spouse's Designated Beneficiary as the Inherited Owner.
