Glossary

**Accumulation Phase.** Begins on the date the Contract is issued and ends on the date the Owner applies the full Contract Value to an Annuity Option or upon Contract termination.

**Annuity Options.** Options available for Annuity Payments.

**Annuity Payments.** Series of payments made pursuant to the Annuity Option(s) elected.

**Contingent Deferred Sales Charge (CDSC).** A charge that may be assessed against each Purchase Payment withdrawn from the Contract. (In some states referred to as surrender charge.)

**Contract.** The MassMutual Transitions Select II Variable Annuity; an individual flexible premium deferred variable annuity<br>contract.

**Contract Anniversary.** An anniversary of the Issue Date of the Contract.

**Contract Value.** The sum of your values in the Sub-Accounts and the DCA Fixed Account during the Accumulation Phase.

**Contract Year.** The first Contract Year is the annual period which begins on the Issue Date and ends on the last calendar day before the first Contract Anniversary. Subsequent Contract Years begin on subsequent Contract Anniversaries.

**DCA Fixed Account.** The DCA Fixed Account, which is part of the General Account, is a fixed account from which assets are systematically transferred to any Sub-Accounts you select.

**Fund(s).** The investment entities into which the assets of the Separate Account will be invested.

**General Account.** The Company's General Investment Account, which supports the Company's annuity and insurance obligations. The General Account's assets include all the assets of the Company with the exception of the Separate Account and the Company's other segregated asset accounts.

**Guaranteed Minimum Accumulation Benefit (GMAB).** For Contracts applied for prior to June 12, 2017, the GMAB was an optional benefit available for an additional cost at the time you purchased your Contract. This feature guarantees a minimum amount for your Contract Value at the end of the benefit period. There are two options which feature different benefit periods (12-Year and 20-Year).

**Joint Owner.** A person entitled to ownership rights under the Contract.

**Owner.** The person(s) or entity entitled to ownership rights under the Contract. We allow multiple Owners, subject to certain restrictions (see ''Ownership''). Where we describe multiple Owners, we refer to them as Joint Owners.

**Purchase Payment(s)**. Any amount paid to us by you or on your behalf with respect to the Contract during the Accumulation Phase, which may be decreased by the assessment of any applicable Premium Tax.

**Qualified Contract.** Your Contract is referred to as a Qualified Contract if it is used to fund a qualified plan such as an Individual Retirement Annuity (IRA), Roth IRA, or a corporate pension and profit-sharing plan (including 401(k) plans and H.R. 10 plans). For information on the types of qualified plans for which the Contract is available, see ''Taxes – Qualified Contracts.''

------

**Separate Account.** The account that holds the assets underlying the Contract that are not allocated to the DCA Fixed Account. The assets of the Separate Account are kept separate from the assets of the General Account and the Company's other separate accounts.

**Sub-Account(s).** The Separate Account assets are divided into Sub-Accounts. The assets of each Sub-Account will be invested in the shares of a single Fund.

| &nbsp;&nbsp; **How are Investment** **Professionals** **Compensated?** | &nbsp;&nbsp;&nbsp;&nbsp; •  Your registered representative may receive compensation, in the form of commissions, for selling this Contract to you.

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 this 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; N/A |

(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.

(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 <sup>®</sup> – Growth Fund. However, this Fund
 is not available directly as an investment choice under your MassMutual variable product. You should read the prospectus along with
 the prospectus for the MML
 VIP American Funds Growth Fund.

 VIP MFS International Equity Fund formerly known as MML International Equity 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) Nomura
 VIP Asset Strategy Series formerly known as Macquarie VIP Asset Strategy Series.
