------

**APPENDIX A: INVESTMENT OPTIONS AVAILABLE UNDER THE CONTRACT** 

The following is a list of Indexed Strategies currently available under the Contract. We may change the features of the Indexed Strategies listed below (including the Index and the current limits on Index gains and losses), offer new Indexed Strategies, and terminate existing Indexed Strategies. We will provide you with written notice before making any changes other than changes to current limits on Index gains. Information about current limits on Index gains is available at <u>www.massmutualascend.com/index-frontier-5-plus</u>. For additional information about the features of the Indexed Strategies, please see the "Indexed Strategies" section in the prospectus. The practical availability of investment options at the time of sale may vary depending on the broker-dealer through which the Contract is sold. See Appendix D – Financial Intermediary Variations in the prospectus.

**Note: If amounts are removed from an Indexed Strategy before the end of its Term, we will apply a Daily Value Percentage adjustment. This may result in a significant reduction in your Strategy value that could exceed any protection from Index loss that would be in place if you held the Indexed Strategy until the end of the Term. You may not be able to invest in certain Indexed Strategies, as noted below.**

<sup>3</sup> This Strategy is only available for Contracts issued before February 21, 2026, unless the Contract is issued in **California**. It will be available for Contracts issued in **California** with a Contract Effective Date before September 7, 2026. 

------

The **S&P 500** is a "price return index," not a "total return index," and therefore does not reflect dividends paid on the securities composing the Index. This will reduce the Index return and cause the Index to underperform a direct investment in the securities composing the Index.

The **iShares MSCI EAFE ETF** deducts fees and costs when calculating Index performance. This will reduce the ETF's return and cause the ETF to underperform a direct investment in the securities composing the ETF.

The **iShares US Real Estate ETF** deducts fees and costs when calculating Index performance. This will reduce the ETF's return and cause the ETF to underperform a direct investment in the securities composing the ETF.

The **SPDR Gold Shares ETF** deducts fees and costs when calculating Index performance. This will reduce the ETF's return and cause the ETF to underperform a direct investment in gold bullion.

The **First Trust Barclays Edge** is an "excess return index" that subtracts a risk-free interest rate from the price and dividend return of the securities. It also deducts fees and costs when calculating Index performance. This will reduce the Index's return and cause the Index to underperform a direct investment in the securities composing the Index.

**Possible Changes in Indexed Strategies.** 

**The S&P 500 1-Year -10% Floor with Cap Indexed Strategy will always be available. At the end of a Term, we may stop offering any other Indexed Strategy. Consequently, any other Indexed Strategy listed above may not be available after the end of the initial Term. We have the right to replace the Index associated with an Indexed Strategy under certain circumstances.** 

**In the future, we may offer new Indexed Strategies. Any new Buffer Strategy will offer protection against loss at least equal to a 5% Buffer. Any new Floor Strategy will offer protection against loss at least equal to a -20% Floor.** 

**Indexed Strategies that may be available in the future may earn a return that is lower than the return your investments would have earned if they had been invested in the other Indexed Strategies that are currently available. In addition, any reduction in the available number of Indexed Strategies may reduce your opportunity to increase your Contract value.** 

The following lists the Fixed Account Option currently available under the Contract. We may change the features of the Fixed Account Option listed below, offer new Fixed Account Options, and terminate existing Fixed Account Options. We will provide you with written notice before doing so.

---

| | | |
|:---|:---|:---|
| **Name** | **Term** | **Minimum Guaranteed Interest Rate** |
|  Declared Rate Strategy | 1 Year | 0.15% |

---

The interest rate for the Declared Rate Strategy Rate will never be less than the guaranteed minimum interest rate from 0.15% to 3.0% set out in the Declared Rate Strategy endorsement included in your Contract. The guaranteed minimum interest rate set out in the endorsement will never be less than the minimum interest rate required for fixed annuity contracts on the Contract Effective Date under the Standard Nonforfeiture Law of the state in which your Contract is issued. For additional information on the Declared Rate Strategy, see the Declared Rate Strategy section in the prospectus.
