Here are a few key reasons why the Plan can be such a sound retirement planning vehicle: Pre-tax contributions to the plan are taken out of your pay before federal income tax is withheld and before you can spend the money elsewhere. These tax-deferred contributions and the growth of your account can benefit from the power of compounding. That s money making money! In addition, as pre-tax contributions are made they can reduce your current gross taxable income. You can choose from carefully selected investment options. If you don t actively choose your investment options, the Plan is designed to invest your contributions into a retirement date based investment option on your behalf. This default option offers professional management and monitoring as well as diversification all in one investment. You may choose new investment options at any time.

Benefits of Your Plan The Cost of Waiting Here s something else you ll want to put to work for you time. The longer your contributions remain invested, the more they can grow through compounding. How long you invest can often be more important than how much you invest. Estimated cost of waiting 10 years to start investing: $248,713 Save for 25 years $183,166 Save for 35 years $431,879 Start Now Automatic enrollment can help you begin your journey to a more secure retirement. Your Plan offers many advantages over other savings options. What you get out of the Plan depends on how much you put into it, how you invest your savings, how those investments perform, and how long you let the Plan work for you. Here s a quick look at some of the Plan s features and benefits: Pre-Tax Saving You make contributions automatically from your paycheck before federal income taxes are deducted. Pre-tax (or tax-deferred) saving can lower your current taxable income, which can lower the federal and state income taxes* you pay during the years you contribute. In fact, you don t pay taxes on your Plan savings, or the earnings on those savings, until you begin withdrawing money from your account. As a retiree you may be in a lower tax bracket than when you made the contributions. * varies per state The information contained in this book is not intended or written as specific legal or tax advice and may not be relied on for purposes of avoiding any federal tax penalties. Neither MassMutual nor any of its employees or representatives are authorized to give legal or tax advice. You must rely on the advice of your own independent tax counsel. Matching Contributions Your employer is offering to put money to work for you by making additional contributions to your Plan account. For more details on your company match, see the Plan Highlights in this book or contact your Plan Administrator. Choices The Plan offers a variety of quality investment options, to help you find the one, or combination, that works for you. If you aren t comfortable making your own investment choices, you can remain in the default investment option, which is established based on your date of birth and a projected retirement age of 65. This retirement date based option provides a diversified portfolio for you, that automatically invests more conservatively as your projected retirement date approaches. Investors should consider an investment's objectives, risks, charges and expenses carefully before investing.

An Overview of Investing We want your journey toward Prepared USA to be a pleasant one. No bumps. No questions about which way to turn. But, even the most experienced travelers may occasionally need information along the way. That s what these next few pages are about. To build your own portfolio, you need to have at least a basic understanding of investing. So you ll want to know something about the different kinds of investments, investment risk, and ways to manage risk through asset allocation. Asset Classes Most investments fall into one of three main categories, or asset classes. It s good to know a little about each of these asset classes. Most retirement plan investment options are categorized as pooled investments where the contributions of many people are pooled and invested together in a selection of other investments by a professional portfolio manager. An individual's contributions typically purchase a fractional portion of all the investments owned by the pooled investment option at the time of contribution. Stable Value s (Cash) Stable value investments, such as Money Market accounts, Certificates of Deposit (CDs), and U.S. Treasury Bills, are essentially loans to a bank or financial institution. You are paid interest for the use of your money. Because the borrowers are considered creditworthy, your investment is generally viewed as a safe one. Stable value investments are one of the most conservative asset classes, so they typically earn lower returns (how much money an investment earns during a period of time) than other types of investments. Investors who prefer lower risk, are nearing retirement, or may need access to their money within a short period of time (one to five years), may wish to consider this asset class. Bonds (Fixed Income) Bonds are loans issued by government entities or companies. Investors who buy bonds are, in effect, lending money to the government or a corporation. In return, investors are paid in the form of interest. The full amount of the bond is repaid when the bond matures. Historically, bonds have been more stable than stocks, but they are not without risk. The primary risk associated with bond investing is that bond prices move up and down, primarily in response to interest rate fluctuations. In addition, another risk is that the bond issuer may not be able to repay the debt. Stocks (Equity) When you buy stock in a corporation you are actually buying ownership, or shares, in that company. As an owner you share in both the profits and losses Hypothetical growth of $10.00 based on historical market returns over a 20-year period (1986-2005). Ending Balance Average Returns Inflation $18.01 2.98% Stable Value $24.74 4.63% Bonds $60.61 9.43% Stocks $95.21 11.93% While all investments noted have outpaced inflation, stocks have historically performed better than stable value and bond investments in the long-term. Past performance does not guarantee future results. This hypothetical chart is for illustrative purposes only and does not intend to reflect the actual performance of any specific investment. Individual experience will likely vary. 1.8 Source: S&P Micropal Stocks = S&P 500 Bonds = U.S. Long-term Government Bond Stable Value = U.S. 30-Day Treasury Bill Inflation = US Bureau of Labor Statistics, Consumer Price Index

of that company. This results in the value of your share increasing or decreasing. The returns on stocks can rise and fall in the short-term, sometimes dramatically. This potential fluctuation in value, or volatility, is why stocks are typically considered risky investments. Stock investors, especially long-term investors, are typically willing to assume this risk because the stock market has, on average, outpaced inflation in the long run.* For the investor looking for long-term growth, stocks have historically been an excellent addition to a diversified portfolio. *Past Performance is no guarantee of future results Types of Stocks There are specific types of stock you may want to know more about before making your investment selections. Here are a few of the major ones: Large Capitalization (Large Cap) Stocks in large, well-established companies ( Blue Chips ), generally with assets over $10 billion, are usually less volatile and often pay regular dividends. Mid Capitalization (Mid Cap) Stocks in mid-sized companies, with assets between $2 billion and $10 billion, tend to be slightly more volatile than large cap stock and have the potential to see more growth in the long-term. Mid market capitalization investing generally involves greater risk than large capitalization investing. Small Capitalization (Small Cap) Stocks in small companies, with less than $2 billion in assets, typically are more volatile than both large and mid cap. The trade-off is that growth in small cap investments may be greater than their large and mid cap counterparts. Small market capitalization investing generally involves greater risk than large capitalization investing. Global/International Although historically considered to be volatile, stocks in non-u.s. companies are not necessarily linked to the direction of U.S. markets. This makes them worth considering as a means to diversify a portfolio. International investing can involve special risks such as political changes and currency fluctuations. There risks are heightened in emerging markets. Style This term refers to the way professional money managers select securities within a specific asset class, such as stocks. Usually, they pick stocks based on two styles: Growth Style Growth style means stocks that are expected to produce above-average earnings growth. Value Style Value style means stocks that are considered to be under-valued or overlooked by the general investing community and the company s stock price will likely rise.

An Overview continued Higher Risk/Reward Potential Stocks Ultra Aggressive Aggressive Risk risk is the chance that an investment will lose money or have a negative return. All investing involves some risk, but not investing for your retirement, or investing too conservatively, could be even riskier. There are three main types of investment risk you ll want to consider. Inflation Risk If your investments do not earn more than the rate of inflation, your money could actually be worth less each year. Social Security is a source of retirement income that is adjusted for inflation. Some investments have been better at beating inflation. For example, stock and bond investments have historically outperformed stable value investments as well as inflation. Past performance is not indicative of future results. Interest-Rate Risk The value of most securities changes in response to interest rates. Bond investments are especially vulnerable to interest rate fluctuations. The price of bond investments will generally decline when interest rates rise and increase when interest rates fall. Bond investments typically invest in a range of investment vehicles with varying interest rates and dates of maturity, which in general helps to moderate interest rate risk. Market Risk The price of a security can fluctuate with changing market conditions; this market risk is the chance that an investment will not increase in value or may lose money. It is also the primary risk people typically think of when they invest in the stock market. Bonds Stable Value Moderate Conservative Short Term Asset Allocation Stocks, bonds, and stable value (e.g. cash) investments respond differently to changing market conditions. Sometimes stock investments perform better; sometimes bond investments do. Stable value investments are affected less by market conditions and tend to grow at a steady, but slower, pace. Diversifying among these asset classes (otherwise known as Asset Allocation) allows you to increase your return potential and reduce the overall risk to your portfolio. Short Term Conservative Moderate Aggressive Ultra Aggressive Lower Risk/Reward Potential Cash/Bonds 95% 70% 40% 15% 0% Stocks 5% 30% 60% 85% 100% This hypothetical chart is for illustrative purposes only and does not reflect the actual performance of any specific investment.

NOTES 2.6

Important Disclosures The performance data given represents past performance and should not be considered indicative of future results. Current performance may be lower or higher than return data quoted herein. For more current information including month-end performance please call 888-643-7343 or visit www.massmutual.com/retire. Principal value and investment return will fluctuate, so that an investor's units when redeemed may be worth more or less than the original investment. portfolio statistics change over time. The investment is not FDIC-insured, may lose value and is not guaranteed by a bank or other financial institution. Pre-inception Returns The separate investment account (SIA) or investment inception date listed is that of this SIA s share class. Other share classes of the SIA may have existed longer. Performance shown is the actual performance of the SIA since the inception date noted. Performance shown prior to the inception date given may include one or both of the following: 1. The oldest share class of the SIA or its underlying investment (depending upon the investment) adjusted for fees and expenses of the newer share class up to the date of inception of the newer share class. If the adjustment would result in better performance for the newer share class than that of the oldest share class (due to lower expenses of the newer share class), then performance shown represents that of the oldest share class without any adjustment up to the date of inception of the newer share class. The fees and expenses are referenced in the report s Operations section. While the inclusion of pre-inception data may provide valuable insight into the probable long-term behavior of newer share classes of an investment, investors should be aware that an adjusted historical return can only provide an approximation of that behavior. For example, the fee structure between a retail share class will vary from that of an institutional share class, as retail share classes tend to have higher operating expenses and sales charges. These adjusted historical returns are not actual returns. Calculation methodologies utilized by Morningstar may differ from those applied by other entities, including the investment itself. 2. A composite of all portfolios managed by the option s subadviser or subadvisers with substantially similar investment objectives, policies and investment strategies and without significant client-imposed restrictions adjusted for the fees and expenses of the share class for this option. Such performance does not represent the actual historical performance of the option or predict its future performance. Performance Fund Return reflects performance of the investment without adjusting for sales charges or the effects of taxation, but is adjusted to reflect all actual ongoing investment expenses and assumes reinvestment of dividends and capital gains (if applicable). If adjusted, sales charges would reduce the performance quoted. In addition, due to market volatility, the investment s return may vary greatly over short periods of time. The investment's performance is compared with that of an index. The index is an unmanaged portfolio of specified securities and does not reflect any initial or ongoing expenses nor can it be invested in directly. An investment s portfolio may differ significantly from the securities in the index. Morningstar chooses the index, which may not be the same as the comparative index noted in the prospectus. Morningstar Proprietary Statistics Please note that some Morningstar proprietary calculations, including the Morningstar Rating, Morningstar Return, and Morningstar Risk may be calculated based on pre-inception returns. Therefore, Morningstar s three-year minimum performance history requirement for Morningstar Rating, Morningstar Return, and Morningstar Risk may be satisfied using pre-inception returns, and the Morningstar Rating, Morningstar Return, and Morningstar Risk may be based, at least in part, on pre-inception returns. Please see the pre-inception returns disclosure (above) for more details. Morningstar Rating For each investment with at least a three-year history, Morningstar calculates a Morningstar Rating based on how an investment ranks on a Morningstar Risk-Adjusted Return measure against other investments in the same category. This measure takes into account variations in an investment s monthly performance after adjusting for sales loads (except for load-waived A shares), redemption fees, and the risk-free rate, placing more emphasis on downward variations and rewarding consistent performance. The top 10% of investments in each category receive 5 stars, the next 22.5% receive 4 stars, the next 35% receive 3 stars, the next 22.5% receive 2 stars and the bottom 10% receive 1 star. The Overall Morningstar Rating for an investment is derived from a weighted average of the ratings for the three-, five- and ten-year (if applicable) time periods. Load-waived A share star ratings do not include any front-end sales load and are intended for those investors who have access to such purchase terms, such as participants in MassMutual-serviced retirement plans. Morningstar Style Box The Morningstar Style Box reveals an investment's investment strategy. For equity investments and fixed-income investments respectively, the vertical axis shows the market capitalization of the stocks owned or the average credit quality of the bonds owned. The horizontal axis shows investment style (value, blend, or growth) or interest rate sensitivity as measured by a bond's duration (short, intermediate or long). Duration is a measure of interest-rate sensitivity, i.e. the longer an investment's duration, the more sensitive the investment s price is to shifts in interest rates. Morningstar Return This statistic is a measurement of an investment's excess return over a risk-free rate (the return of the 90-day Treasury bill), after adjusting for all applicable loads and sales charges. In each Morningstar Category, the top 10% of investments earn a High Morningstar Return, the next 22.5% Above Average, the middle 35% Average, the next 22.5% Below Average, and the bottom 10% Low. Morningstar Return is measured for up to three time periods (three-, five-, and 10-years). These separate measures are then weighted and averaged to produce an overall measure for the investment. s with less than three years of performance history are not rated. For more information, please see Morningstar Proprietary Statistics (above). Morningstar Risk This statistic evaluates the variations in an investment's monthly returns, with an emphasis on downside variations. In each Morningstar Category, the 10% of investments with the lowest measured risk are described as Low Risk, the next 22.5% Below Average, the middle 35% Average, the next 22.5% Above Average, and the top 10% High. Morningstar Risk is measured for up to three time periods (three-, five-, and 10-years). These separate measures are then weighted and averaged to produce an overall measure for the investment. s with less than three years of performance history are not rated. For more information, please see Morningstar Proprietary Statistics (above). Risk Foreign Securities s/emerging Market s: The investor should note that investments that invest in foreign securities involve special additional risks. These risks include, but are not limited to, currency risk, political risk, and risk associated with varying accounting standards. Investing in emerging markets may accentuate these risks. Sector s: Sector investments may experience greater short-term price volatility than more diversified investments, and are most suitable for use in the aggressive portion of an investment portfolio. Non-Diversified s: The investor should note that investments that invest more of their assets in a single issuer involve additional risks, including unit price fluctuations, because of the increased concentration of investments. Small/Mid Cap s: s in companies with small or mid market capitalization ( small caps or mid caps ) may be subject to special risks given their characteristic narrow markets, limited financial resources, and less liquid stocks, all which may cause price volatility. High-Yield Bond s: High-yield bond investments are subject to greater credit risks than high quality bond investments. As interest rates rise, bond prices fall. As such, this investment s unit value may decline substantially, and it is possible to lose a significant portion of your principal when interest rates rise. Money Market: The investor should note an investment in a money market investment is neither insured nor guaranteed by the Federal Deposit Insurance Corporation or any other government agency. Although the investment seeks to preserve the value of your investment at $1.00 per share, it is possible to lose money by investing in the investment. Inflation-Protected: The investment may be appropriate for investors seeking to achieve as high a total rate of return as is considered consistent with prudent investment risk and the preservation of capital. The investment invests primarily in inflation-indexed bonds issued by the US and non-us governments, their agencies or government-sponsored enterprises, and corporations. Risks of investing in the investment include credit risk, interest rate risk and foreign investment risk. Foreign investments involve risks such as currency fluctuations, market price swings, less public information and economic, social and political uncertainty. Neither the investment nor its yield is guaranteed by the US Govt. The investment prospectus includes additional detail on risk and reward. Multi- Options: It is important to note that an investment option with underlying investments may be subject to the expenses of those underlying investments in addition to those of the investment option itself. Destination Retirement 2040/Ultra Aggressive Journey: The investor should note that a significant percentage of the underlying investments in these strategies have a higher than average risk exposure, such as small, mid cap and international stocks. Investors should consider their risk tolerance carefully before choosing such a strategy.

Release Date: 06-30-2008 T. Rowe Price Retirement Income Fund PARIX Class Advisor... Overall Morningstar Rating Morningstar Return Morningstar Risk DJ Portfolio Target 2010 TR USD QQQQ Above Average Average Out of 131 Target-Date 2000-2014 funds. An investment's overall Morningstar Rating, based on its risk-adjusted return, is a weighted average of its applicable 3-, 5-, and 10-year Ratings. See disclosure for more detail. Strategy The investment seeks the highest total return over time consistent with an emphasis on both capital growth and income. The fund invests in a set of underlying T. Rowe Price mutual funds representing various asset classes and sectors. It expects to invest 41.5% of assets in stock funds, 28.50% in fixed income funds 30.00% in short-term income funds. While the fund is nondiversified, it invests in diversified underlying funds. Category Description: Target-Date 2000-2014 Target-date portfolios provide diversified exposure to stocks, bonds, and cash for those investors who have a specific date in mind (in this case, the years 2000-2014) for retirement or another goal. These portfolios aim to provide investors with an optimal level of return and risk, based solely on the target date. These portfolios get more conservative as the goal date approaches by investing more in bonds and cash. managers structure these portfolios differently; two funds with the same goal year may have different allocations to equities and therefore different levels of return and risk. Volatility Analysis Low Moderate High Category In the past, this investment has shown a relatively small range of price fluctuations relative to other investments. Based on this measure, currently more than two thirds of all investments have shown higher levels of risk. Consequently, this investment may appeal to investors looking for a conservative investment strategy.

While the fund is nondiversified, it invests in diversified underlying funds. Category Description: Target-Date 2030+ Target-date portfolios provide diversified exposure to stocks, bonds, and cash for those investors who have a specific date in mind (in this case, the years 2030+) for retirement or another goal. These portfolios aim to provide investors with an optimal level of return and risk, based solely on the target date. These portfolios get more conservative as the goal date approaches by investing more in bonds and cash. managers structure these portfolios differently; two funds with the same goal year may have different allocations to equities and therefore different levels of return and risk. Volatility Analysis Low Moderate High Category In the past, this investment has shown a relatively moderate range of price fluctuations relative to other investments. This investment may experience larger or smaller price declines or price increases depending on market conditions. Some of this risk may be offset by owning other investments with different portfolio makeups or investment strategies.

Overall Morningstar Rating Morningstar Return Morningstar Risk Russell 2000 Growth TR USD QQQQ Average Below Average Out of 705 Small Growth funds. An investment's overall Morningstar Rating, based on its risk-adjusted return, is a weighted average of its applicable 3-, 5-, and 10-year Ratings. See disclosure for more detail. Strategy The investment seeks long-term capital appreciation. The fund invests primarily in common stocks and equity securities of smaller companies which the managers believe offer potential for long-term growth. It may maintain cash reserves for liquidity and defensive purposes. The fund normally invests at least 80% of assets in the securities of companies whose market capitalizations fall within the range of companies in the Russell 2000 index or the S&P Small Cap 600 index. Past name(s): MassMutual Small Cap Growth Equity. Category Description: Small Growth Small-growth funds focus on faster-growing companies whose shares are at the lower end of the market-capitalization range. These funds tend to favor companies in up-and-coming industries or young firms in their early growth stages. As a result, the category tends to move in sync with the market for initial public offerings. Many of these funds invest in the technology, health-care, and services sectors. Because these businesses are fast-growing and often richly valued, their stocks tend to be volatile. Volatility Analysis Low Moderate High Category In the past, this investment has shown a wide range of price fluctuations relative to other investments.
