If the Contract is owned by a non-natural person, then Age shall mean attained age of the Annuitant as of his/her last birthday.

See “The Annuity Phase – Non-Lifetime Contingent Option – Period Certain Annuity Option.” The term Annuitant also includes the joint Annuitant, if any. The Annuitant has no rights to the Contract.

• it includes all information necessary for us to execute the request or transaction; and

 

• it is signed by you or persons authorized to provide instruction to engage in the request or transaction.
 

A request or transaction may be rejected or delayed if not in Good Order. Good Order generally means the actual receipt by our Service Center of the instructions related to the request or transaction in writing (or, when permitted, by telephone or internet) along with all forms, information and supporting legal documentation we require to effect the request or transaction. This information generally includes to the extent applicable: the completed application or instruction form; your Contract number; the transaction amount (in dollars or percentage terms); the names and allocation to and/or from the Sub-Accounts affected by the request or transaction; the signatures of all Owners; if necessary, Social Security Number or Tax Identification number; tax certification; and any other information or supporting documentation we may require including consents, certifications and guarantees. Instructions must be complete and sufficiently clear so that we do not need to exercise any discretion to follow such instructions. We will not accept instructions that require additional requirements or burdens not provided for within the Contract. With respect to Purchase Payments, Good Order also generally includes receipt by us of sufficient funds to affect the purchase. We may, in our sole discretion, determine whether any particular request or transaction is in Good Order, and we reserve the right to change or waive any Good Order requirements at any time. If you have any questions you may contact our Service Center before submitting the form or request. See “Purchasing a Contract – Sending Requests in Good Order” for more information.

Important Information You Should Consider About the Contract

FEES, EXPENSES, AND ADJUSTMENTS

LOCATION IN PROSPECTUS

Are There Charges or Adjustments for Early Withdrawals?

Yes. If you withdraw money from your B-Share Contract within  five years following your last Purchase Payment, you may be assessed a Contingent Deferred Sales Charge (CDSC) of up to 7% of the Purchase Payment withdrawn (less a 10% free withdrawal amount), declining to 0% after the fifth year.
For example, if you purchased the Contract and withdraw the $100,000 initial Purchase Payment during the first two years after your Purchase Payment, you could be assessed a charge of up to $6,300 on the Purchase Payment withdrawn. This 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 Sub-Accounts during the Accumulation Phase. However, we reserve the right to charge $20 per transfer in excess of 12 in a single calendar year.

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.

•

The B-Share 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 five years (for B-Share Contracts) following your last Purchase Payment.

•

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 has its own unique risks.

•

You should review the investment options, including prospectuses for the available Funds, before making an investment decision.

Principal Risks of Investing in the Contract

What are the Risks Related to the Insurance Company?
•

Any obligations, 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 at www.MassMutual.com/ratings.

RESTRICTIONS

LOCATION IN PROSPECTUS

Are There Restrictions on the Investment Options?

Yes.

•

Currently, there is no charge when you transfer Contract Value among Sub-Accounts. However, we reserve the right to charge $20 per transfer in excess of 12 in a single calendar year.

•

We reserve the right to remove or substitute Funds as investment options that are available under the Contract.

•

We reserve the right to limit transfers if frequent or large transfers occur.

•

If you have selected the ROP Death Benefit, there are allocation restrictions.

General Information about Massachusetts Mutual Life Insurance Company, the Separate Account and the Investment Options – The Funds
Transfers and Transfer Programs – Limits on Frequent Trading and Market Timing Activity
Death Benefit – ROP Death Benefit – ROP Death  Benefit Allocation Restrictions

Are There Any Restrictions on Contract Benefits?

Yes.

•

The Return of Purchase Payment Death Benefit (ROP Death Benefit) is not available for selection if the oldest Owner (or Annuitant, if the Owner is a non-natural person) is over the Age of 75.

•

If you select the ROP  Death Benefit, you will be subject to allocation restrictions. This means you will be limited in your choice of Sub-Account investments. 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 the ROP  Death Benefit. 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 the ROP  Death Benefit.

•

If you select the ROP  Death Benefit, you cannot later select another death benefit feature.

•

If you elect the ROP  Death Benefit we will deduct an additional charge from each Sub-Account in which you are invested to compensate us for the costs associated with this Death Benefit.

•

Withdrawals will negatively impact the ROP  Death Benefit.

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.

•

For certain distribution channels, this product is no longer available in the tax-qualified market.

Taxes

CONFLICTS OF INTEREST

LOCATION IN PROSPECTUS

How are Investment Professionals Compensated?
•

Your registered representative may receive 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 help these registered representatives and their supervisors qualify for such benefits.

•

This conflict of interest may influence your registered representative to offer or recommend this Contract over another investment.

Distribution

Should I Exchange my Contract?
•

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.

(7) MML VIP Moderate Allocation Fund formerly known as MML Moderate 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.

(19) 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.
(20) The MML VIP American Funds Growth Fund invests all of its assets in the Class 1 shares of the American Funds Insurance Series® – Growth Fund.

You should read the prospectus along with the prospectus for the MML VIP American Funds Growth Fund.

(33) 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.
(34) While the ROP Death Benefit is in effect, you may not allocate Purchase Payments or Contract Value to this Fund.
(35) Nomura VIP Asset Strategy Series formerly known as Macquarie VIP Asset Strategy Series.
