This Rate Sheet Prospectus Supplement ("Rate Sheet") should be read carefully and retained with your Prospectus. You should not purchase an Income Guarantee Feature without first obtaining the applicable Rate Sheet.

We are issuing this Rate Sheet to update certain Income Guarantee Feature Terms applicable to one or more of our Income Guarantee Features. For the Income Guarantee Feature Terms applicable to your Income Guarantee Feature, see: Appendix A -  RetirePay, Appendix B - RetireCore, and Appendix C - RetireCore  Stacking. For complete information about the Income Guarantee Features, see the "Additional Benefits - Income Guarantee Features" section in the Prospectus.

The Income Guarantee Feature Terms included in this Rate Sheet are effective for applications submitted on or after February 20, 2026 ("Rate Sheet Effective Date") until a new Rate Sheet is effective that replaces and supersedes this Rate Sheet. See "Rate Sheet Comparison Process" for applications submitted prior to the Rate Sheet Effective Date. This Rate Sheet replaces and supersedes any previously issued Rate Sheet.

This Rate Sheet has no specified end date. If we change the Income Guarantee Feature Terms, we will issue a new Rate Sheet. In the event we issue a new Rate Sheet, we will provide at least 10 business days' notice of the effective date of the superseding Rate Sheet.

Rate Sheet Eligibility Conditions

Certain Rate Sheet eligibility conditions apply when we have issued a subsequent Rate Sheet after you apply for your Contract and prior to your Issue Date.

In order for the Income Guarantee Feature Terms in this Rate Sheet to apply to your Contract, your necessary application information, including any applicable transfer form(s), must be submitted to an order entry system utilized to issue the Contract ("application submit date") on or after February 20, 2026 and prior to the effective date of the superseding Rate Sheet.  For purposes of this process, the application submit date is also defined to include the date the application is signed if a paper application is necessary.

Application Requirements

The application information must be in Good Order within 10 business days after the application submit date, including completion of the broker-dealer suitability review. We also require payment of at least the minimum initial Purchase Payment within 10 Business Days after the application submit date (90 calendar days if you plan to pay the initial Purchase Payment with proceeds from an IRS Section 1035 exchange or direct transfer).

If these Rate Sheet Eligibility Conditions are met, and the Contract is issued, the Income Guarantee Feature Terms in this Rate Sheet will apply, unless a beneficial superseding rate sheet applies, as described under "Rate Sheet Comparison Process."

If these Rate Sheet Eligibility Conditions are not met, we will cancel the application and return any Purchase Payment received.

If these Rate Sheet Eligibility Conditions are not met and your initial Purchase Payment was paid with proceeds from an IRS Section 1035 exchange or direct transfer, we will inform you and request instructions regarding whether to issue the Contract with the Income Guarantee Feature Terms in effect under the superseding Rate Sheet or cancel the application. If you have not provided us with the requested instructions within 2 Business Days after we have received your Purchase Payment, we will return your Purchase Payment to the original  source.

Rate Sheet Comparison Process

Subject to satisfying the Rate Sheet Eligibility Conditions established in this Rate Sheet, if your application is submitted prior to the Rate Sheet Effective Date and your contact is issued on or after the Rate Sheet Effective Date, this Rate Sheet will apply if there are only beneficial changes to the terms of the Income Guarantee Feature you selected. If your contract is issued before the Rate Sheet Effective Date, this Rate Sheet will not apply and you will receive the Rate Sheet that was effective as of your application submit date.

The changes will be considered to be beneficial unless any of the following occurs for the Income Guarantee Feature you selected:
