**NOTICE OF FUND SUBSTITUTION**

The purpose of this Supplement is to announce a fund change. Capitalized terms used in this Supplement are defined in your Prospectus unless otherwise defined here. "We," "Us," or "Our" refer to Massachusetts Mutual Life Insurance Company. "You" or "Your" refer to the Owner of the Policy.

At the close of the New York Stock Exchange ("NYSE") on or about November 14, 2025 (the "Substitution Date"), in accordance with applicable law, shares of the following Existing Fund will be replaced with shares of the following Replacement Fund (the "Substitution"), set forth in the table below:

---

| | |
|:---|:---|
| **Existing Fund (Share Class)** | **Replacement Fund (Share Class)** |
| Invesco V.I. Main Street Fund<sup>®</sup> (Series I) | MML Fundamental Equity Fund (Class II) |

---

 

**Transfer of Policy Value from the Existing Fund**

On the Substitution Date, all Policy Value in the Sub-Account investing in the Existing Fund will automatically be reallocated to the Sub-Account investing in the corresponding Replacement Fund. Such reallocation will not count toward transfer limits imposed by Our frequent trading and market timing policies. After the Substitution Date, You may not make any allocations to the Sub-Account investing in the Existing Fund, and such Sub-Account will no longer be available for investment under the Policy.

The Substitution will occur at the relative net asset values of the Existing Fund's and Replacement Fund's shares. Your Policy Value immediately prior to the Substitution will equal Your Policy Value immediately after the Substitution. There will not be any tax consequences for You as a result of the Substitution. The Substitution will be performed at no cost to You. The fees and charges under Your Policy will not increase as a result of the Substitution. The overall fees and expenses of the Replacement Fund are equal to or less than those of the corresponding Existing Fund. Your rights and Our obligations will not be altered in any way.

If Your Policy Value is automatically transferred on the Substitution Date, You will receive a confirmation showing the transfer of Your Policy Value from the Sub-Account that invests in the Existing Fund to the Sub-Account that invests in the corresponding Replacement Fund.

**Impact on Transaction Requests**

The Sub-Account that invests in the Existing Fund will continue to be available for premium payments, allocation elections, transfers, loans, and withdrawals until the close of the NYSE on the Substitution Date. Any premium payment, allocation election, transfer, loan, or withdrawal request involving the Sub-Account that invests in the Existing Fund on or after the Substitution Date will default to the Sub-Account that invests in the corresponding Replacement Fund.

**Impact on Future Premium Payment Allocations**

On the Substitution Date, the Replacement Fund will automatically replace the corresponding Existing Fund under Your premium payment allocation instructions.

If You do not wish to have Your future premium payments allocated to the Replacement Fund, You must send a request in good order to Our Administrative Office to change Your premium payment allocation instructions.

**Transfer Rights**

On the Substitution Date, any Policy Value remaining in the Sub-Account that invests in the Existing Fund will be automatically reallocated to the Sub-Account that invests in the corresponding Replacement Fund.

From the date of this Supplement until the Substitution Date, You may transfer Your Policy Value allocated to a Sub-Account that invests in the Existing Fund to any other Sub-Account available under Your Policy free of charge.

For 30 calendar days following the Substitution Date, You may transfer Your Policy Value allocated to a Sub-Account that invests in the Replacement Fund to any other Sub-Account available under Your Policy free of charge.

Such transfers will not count as a transfer for purposes of any limitation on the number of transfers permitted under Your Policy or transfer limits imposed by Our frequent trading and market timing policies. We will not charge a transfer fee for such transfers.

From the date of this Supplement to the Substitution Date, and for 30 calendar days after the Substitution Date, We will not exercise any rights reserved under the Policy to impose additional restrictions on transfers between Sub-Accounts.
