For information on the types of qualified plans for which the Certificate is available, see "Taxes - Qualified Contracts."

RISKS

LOCATION IN PROSPECTUS

Risk of Loss

You can lose money by investing in this Certificate, including loss of principal.

Principal Risks of Investing in the Certificate

Not a Short-Term Investment

This Certificate is not designed for short-term investing and is not appropriate for an investor who needs ready access to cash.

CDSCs may apply for up to nine years following your Certificate Issue Date.

If CDSCs apply, they will reduce the value of your Certificate if you withdraw money during that time. The benefits of tax deferral also mean the Certificate is more beneficial to investors with a long time horizon.

CONFLICTS OF INTEREST

LOCATION IN PROSPECTUS

Investment Professional Compensation

Your registered representative may have received compensation, in the form of commissions, for selling this Certificate to you. If your registered representative is also a MassMutual insurance agent, they are also eligible for certain cash and non-cash benefits from MassMutual. Cash compensation includes bonuses and allowances based on factors such as sales, productivity and persistency (Certificate retention). Non-cash compensation includes various recognition items such as prizes and awards as well as attendance at, and payment of the costs associated with attendance at, conferences, seminars and recognition trips, and also includes contributions to certain individual plans such as pension and medical plans. Sales of the Certificate  may have helped these registered representatives and their supervisors qualify for such benefits.

This conflict of interest may have influenced your registered representative to offer or recommend this Certificate  over another investment.

Other Information - Distribution

Exchanges

Because the Certificate is no longer sold, you would not be affected by a scenario in which you are asked to replace an existing annuity contract you own with a new purchase of this Certificate. However, in general you should be aware that some investment professionals may have a financial incentive to offer you a new contract in place of the one you already own. Thus, in general, you should only exchange your annuity contract if you determine, after comparing the features, fees, and risks of both contracts, that it is preferable for you to purchase the new annuity rather than continue to own the existing annuity.

(*) These Funds and their investment advisers have entered into contractual fee waivers or expense reimbursements. These temporary fee reductions are reflected in their current expenses. Those contractual arrangements are designed to reduce the Fund's total current expenses for Owners and will continue past the current year.
(1) These are fund-of-funds investment choices. They are known as fund-of-funds because they invest in other underlying funds. A fund offered in a fund-of-funds structure may have higher expenses than a direct investment in its underlying funds because a fund-of-funds bears its own expenses and indirectly bears its proportionate share of expenses of the underlying funds in which it invests.
(2) You could lose money by investing in the Fund. Although the Fund seeks to preserve the value of your investment at $1.00 per share, it cannot guarantee it will do so. An investment in the Fund is not insured or guaranteed by the Federal Deposit Insurance Corporation or any other government agency. The Fund's sponsor has no legal obligation to provide financial support to the Fund, and you should not expect that the sponsor will provide financial support to the Fund at any time. The yield of this Fund may become very low during periods of low interest rates. After deduction of Separate Account charges, the yield in the division that invests in this Fund could be negative.
(3) Unavailable in Certificates issued on or after January 19, 2008.
(4) Invesco V.I. Equity and Income Fund was added as an investment option on April 29, 2024.
(5) Invesco V.I. Conservative Balanced Fund merged into Invesco V.I. Equity and Income Fund after the close of the New York Stock Exchange on April 26, 2024.
(6) Unavailable in Certificates issued on or after April 30, 2012.
(7) The Fund is a "feeder" fund, meaning that it does not buy investment securities directly, but instead invests in shares of a corresponding "master" fund, which in turn purchases investment securities. A fund offered in a master feeder structure may have higher expenses than those of a fund which invests directly in securities because the "feeder" fund bears its own expenses in addition to those of the "master" fund. You should read the Fund prospectuses for more information about this "feeder" fund.
(8) The MML American Funds Growth Fund invests all of its assets in the Class 1 shares of the American Funds Insurance Series® - Growth Fund. However, this Fund is not available directly as investment choices under your MassMutual variable product. You should read the prospectus along with the prospectus for the MML American Funds Growth Fund.
(9) Specialty funds are an all-encompassing category that consists of funds that forgo broad diversification to concentrate on a certain segment of the economy or a specific targeted strategy. For example, sector funds are targeted strategy funds aimed at specific sectors of the economy, such as financial, technology, healthcare, and so on. Sector funds can, therefore, be more volatile than a more diversified equity fund since the stocks in a given sector tend to be highly correlated with each other.
