Important Information You Should Consider About the Contract

FEES, EXPENSES, AND ADJUSTMENTS

LOCATION IN PROSPECTUS

Are There Charges or Adjustments for Early Withdrawals?

Yes.
Standard  CDSC. If you withdraw money from your Contract within 7 years following your Issue Date, you may be assessed a Contingent Deferred Sales Charge (CDSC) of up to 7% of the amount withdrawn (less a 10% free withdrawal amount) or applied to Annuity Option E, declining to 0% after the seventh year.
For example, if you elect the Standard CDSC under the Contract and we issued your Contract with a $100,000 Purchase Payment, and you withdrew the $100,000 Purchase Payment during the first two years after your Issue Date, you could be assessed a charge of up to $6,300 on the amount withdrawn.
Optional Nine Year CDSC. If you withdraw money from your Contract within 9 years following your Issue Date, you may be assessed a CDSC of up to 8% of the amount withdrawn (less a 10% free withdrawal amount) or applied to Annuity Option E, declining to 0% after the ninth year.
For example, if you elect the Optional Nine Year CDSC under the Contract and we issued your Contract with a $100,000 Purchase Payment, and you withdrew the $100,000 Purchase Payment during the first two years after your Issue Date, you could be assessed a charge of up to $7,200 on the amount withdrawn.
The impact of the CDSC shown in these examples could result in a loss of principal regardless of market performance. This loss will be greater if income taxes or premature distribution taxes apply.

Charges and Deductions - Contingent Deferred Sales Charge (CDSC)

Are There Transaction Charges?

No. Currently, we do not assess a charge to transfer Contract Value among the investment options during the Accumulation Phase. However, we reserve the right to charge $20 per transfer in excess of 12 in a single calendar year.

(3) This charge is the current charge for the least expensive optional benefit, the Nursing Home Waiver Benefit. In the first Contract Year, the charge is a percentage of your Purchase Payments. On the last day of your first Contract Year and on the last day of each Contract Year thereafter, the annual charge is a percentage of your Contract Value on that date.
(4) This charge is the current charge for the most expensive optional benefit, the MassMutual Guaranteed Income Plus 5 or 6 (GMIB 5 or GMIB 6). The charge is equal to, on an annual basis, a percentage of your GMIB value deducted quarterly in arrears while the feature is in effect.
(5) The calculation of the highest annual cost assumes the election of the following optional features: GMIB 5 or GMIB 6, the Annual Ratchet Death Benefit, the 10%/20% Free Withdrawal Benefit, the Nursing Home Waiver Benefit and the Equalizer Benefit.

RISKS

LOCATION IN PROSPECTUS

Is There a Risk of Loss from Poor Performance?

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

Principal Risks of Investing in the Contract

Is This a Short-Term Investment?

No.

•

This Contract 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 seven years (nine years if the optional nine year  CDSC schedule is elected) following your Issue Date on amounts withdrawn that exceed the free withdrawal amount or when Contract Value is applied to Annuity Option E.

•

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

•

Withdrawals may result in income taxes and premature distribution taxes.

Principal Risks of Investing in the Contract

What are the Risks Associated with the Investment Options?

•

An investment in this Contract is subject to the risk of poor investment performance of the Funds you choose and can vary depending upon the performance of the funds available under the Contract.

•

Each Fund and fixed account has its own unique risks.

•

You should review the investment options, including prospectuses for the available Funds and the terms of any fixed account, before making an investment decision.

Principal Risks of Investing in the Contract

What are the Risks Related to the Insurance Company?

•

Any obligations (including under any fixed account), guarantees, and benefits of the Contract are subject to the claims-paying ability of MassMutual. If MassMutual experiences financial distress, it may not be able to meet its obligations to you. More information about MassMutual, including its financial strength ratings, is available by request by calling (800) 272-2216 or by visiting www.MassMutual.com/ratings.

RESTRICTIONS

LOCATION IN PROSPECTUS

Are There Any Restrictions on Contract Benefits?

Yes.

•

We limit the investment options available if you are participating in any of the following optional benefits. This means you will be limited in your choice of Sub-Account investments and may be limited in how much you can invest in certain Sub-Accounts. This also means you will not be able to allocate Contract Value to all of the Sub-Accounts that are available to Owners who have not elected one of these optional benefits. We impose allocation restrictions to reduce the risk of investment losses that may require us to use our General Account assets to honor the guarantee under these optional benefits. We may change these restrictions in the future.

         ○   MassMutual Lifetime Income Protector
         ○    Guaranteed Minimum Accumulation Benefit
         ○    Guaranteed Minimum Income Benefit
         ○   MassMutual Lifetime Payment Plus  

•

Since we no longer offer this Contract for sale, you may no longer elect any additional optional benefits under this Contract.

•

For certain optional benefits, withdrawals, including withdrawals that exceed limits specified by the terms of the optional benefit, may affect the availability of the benefit by reducing the benefit by an amount greater than the value withdrawn and/or could terminate the benefit. See ''Additional Benefits - Guaranteed Minimum Accumulation Benefit,'' ''Additional Benefits - Guaranteed Minimum Income Benefit,'' ''Additional Benefits - MassMutual Lifetime Income Protector,''   and ''Additional Benefits - MassMutual Lifetime Payment Plus.''  

•

If you are participating in the Guaranteed Minimum Accumulation Benefit, Guaranteed Minimum Income Benefit, MassMutual Lifetime Payment Plus, or MassMutual Lifetime Income Protector, you may not participate in the Separate Account Dollar Cost Averaging Program, Automatic Rebalancing Program, Interest Sweep Option, or any fixed account.

•

If you are participating in MassMutual Lifetime Income Protector, the Guaranteed Minimum Accumulation Benefit, the Guaranteed Minimum Income Benefit, or MassMutual Lifetime Payment Plus and elected a Directed Allocation Model, the Custom Allocation Choice program or the Custom Allocation Choice Select program, you agree to authorize us to automatically rebalance your Contract Value among the Sub-Accounts available under the Program on a periodic basis to continue to follow the Custom Allocation Choice program or Custom Allocation Choice Select program investment parameters.

•

You cannot elect the Annual Ratchet Death Benefit if you are participating in the MassMutual Lifetime Income Protector.

•

You may only participate in one death benefit at a time.

TAXES

LOCATION IN PROSPECTUS

What are the Contract's Tax Implications?

•

You should consult with a tax professional to determine the tax implications of an investment in and payments received under the Contract.

•

If your Contract is funding a qualified retirement plan or individual retirement annuity (IRA), you do not receive any additional tax deferral.

•

Earnings on your Contract are taxed at ordinary income tax rates when you withdraw them, and you may have to pay an additional income tax if you take a withdrawal before age 59½. Earnings for this purpose consist of Contract Value in excess of your after-tax investment (cost basis) in the Contract.

Taxes

CONFLICTS OF INTEREST

LOCATION IN PROSPECTUS

How are Investment Professionals Compensated?

•

Your registered representative may have received compensation, in the form of commissions, for selling this Contract 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 (contract 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 Contract 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 Contract over another investment.

Distribution

Should I Exchange my Contract?

•

Because the Contract 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 Contract. 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, and any fees or penalties to terminate your existing contract, that it is preferable for you to purchase the new annuity rather than continue to own the existing annuity.

(*) This Fund is subject to an expense reimbursement or fee waiver arrangement. As a result, this Fund's annual expenses reflect temporary expense reductions. See the Fund prospectus for additional information.
(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) MML VIP Aggressive Allocation Fund formerly known as MML Aggressive Allocation Fund.
(3) MML VIP American Funds 65/35 Allocation Fund formerly known as MML American Funds Core Allocation Fund.

(8) 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.

(22) 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.
(23) The MML American Funds Growth Fund invests all of its assets in the Class 1 shares of the American Funds Insurance Series® - Growth Fund.

(37) 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.

(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.

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.

(21) 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.
(22) The MML American Funds Growth Fund invests all of its assets in the Class 1 shares of the American Funds Insurance Series® - Growth Fund.

(36) 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.
