|  | **RESTRICTIONS** | **LOCATION IN** **PROSPECTUS** |
| &nbsp;&nbsp; **Are There Any Restrictions** **on Contract Benefits?** | &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; **Yes.**<br> •  You may not elect the HQV Death Benefit if you elect an Income Guarantee Feature.<br> •  Your Contract will be subject to investment allocation restrictions while an Income Guarantee Feature is in effect. 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. We impose these allocation restrictions to reduce the risk of investment losses that may require us to use our General Account assets to honor the guarantees under the Income Guarantee Features.<br> •  If you have elected an Income Guarantee Feature, withdrawals that are prior to the Guaranteed Lifetime Withdrawal Date are Excess Withdrawals. On or after the Guaranteed Lifetime Withdrawal Date, the portion of a withdrawal (including CDSCs) from the Contract Value that causes the cumulative withdrawals to exceed the ALBA in that Contract Year will be an Excess Withdrawal unless the withdrawal is taken as a part of the Company's Systematic Withdrawal Program established for the payment of RMDs, under which the RMD is calculated by the Company and no other withdrawals are taken within the Contract Year. Any withdrawal that occurs after the cumulative withdrawals exceed the ALBA in that Contract Year will also be an Excess Withdrawal. Excess Withdrawals can result in a significant reduction or elimination of your Benefit Base, depending upon the amount of the withdrawal. An Excess Withdrawal will also reduce the Roll-Up Base for RetireCore and RetireCore Stacking, and the Roll-Up Value for RetireCore.<br> •  After the first Contract Year, you may not make additional Purchase Payments that total more than $10,000 in a Contract Year while RetirePay is in effect, and $25,000 in a Contract Year while either RetireCore or RetireCore Stacking are in effect. You may not make additional Purchase Payments on or after the Guaranteed Lifetime Withdrawal Date while an Income Guarantee Feature is in effect or after you elect the Income Guarantee Feature Charge Increase Opt-Out.<br> •  Once you select a death benefit, it cannot be canceled or changed.<br> •  Withdrawals (including withdrawals of the ALBA if an Income Guarantee Feature is in effect) will negatively impact the ROP Death Benefit.<br> •  Withdrawals will negatively impact the HQV Benefit.<br> •  If you elect the HQV Death Benefit, once the Contract Anniversary after the oldest Owner (or oldest Annuitant, if the Contract is owned by a non-natural person) attains age 80 has occurred, the Annual Lock-In Feature (ALIF) will no longer recalculate on each Contract Anniversary. The ALIF will remain as the last calculated ALIF adjusted by subsequent Purchase Payments and withdrawals. | &nbsp;&nbsp; Additional Benefits – Income Guarantee Features<br>Death Benefit – Death Benefit During the Accumulation Phase – Highest Quarterly Value (HQV) Death Benefit |

|  | **TAXES** | **LOCATION IN** **PROSPECTUS** |
| &nbsp;&nbsp; **What are the Contract's** **Tax Implications?** | &nbsp;&nbsp;&nbsp;&nbsp; •  You should consult with a tax professional to determine the tax implications of an investment in and payments received under the Contract.<br> •  If your Contract is funding a qualified retirement plan or individual retirement annuity (IRA), you do not receive any additional tax benefit.<br> •  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. | &nbsp;&nbsp; Taxes |

|  | **CONFLICTS OF INTEREST** | **LOCATION IN** **PROSPECTUS** |
| &nbsp;&nbsp; **How are Investment** **Professionals** **Compensated?** | &nbsp;&nbsp;&nbsp;&nbsp; •  Your registered representative may receive compensation, in the form of commissions, for selling the 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.<br> •  This conflict of interest may influence your registered representative to offer or recommend the Contract over another investment. | &nbsp;&nbsp; Distribution |
| &nbsp;&nbsp; **Should I Exchange my** **Contract?** | &nbsp;&nbsp;&nbsp;&nbsp; •  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. | &nbsp;&nbsp; Purchasing a Contract |

 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.

(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.

(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.
