Risk/Return Summary

WHAT IS THE FUND'S INVESTMENT OBJECTIVE?

The Fund is a money market fund that seeks to maintain a stable net asset value (NAV) of $1.00 per share. The Fund's investment objective is current income with stability of principal and liquidity. While there is no assurance that the Fund will achieve its investment objective, it endeavors to do so by following the strategies and policies described in this prospectus.

WHAT ARE THE FUND'S MAIN INVESTMENT STRATEGIES?

The Fund invests only in a portfolio of short-term U.S. Treasury and government agency securities that pay interest exempt from state personal income tax. The dollar-weighted average maturity of the Fund's portfolio will be 90 days or less.

WHAT ARE THE MAIN RISKS OF INVESTING IN THE FUND?

All mutual funds take investment risks. Therefore, even though the Fund is a money market fund that seeks to maintain a stable NAV, it is possible to lose money by investing in the Fund.

The Shares offered by this prospectus are not deposits or obligations of any bank, are not endorsed or guaranteed by any bank and are not insured or guaranteed by the U.S. government, the Federal Deposit Insurance Corporation, the Federal Reserve Board, or any other government agency.

Risk/Return Bar Chart and Table

Historically, the Fund has maintained a constant $1.00 NAV per share. The bar chart shows the variability of the Fund's total returns on a calendar year-end basis.

The Fund's Shares are sold without a sales charge (load). The total returns displayed above are based on NAV.

The Fund's total return for the three-month period from January 1, 2002 to March 31, 2002 was 0.34%.

Within the period shown in the bar chart, the Fund's highest quarterly return was 1.52% (quarter ended September 30, 2000). Its lowest quarterly return was 0.52% (quarter ended December 31, 2001).

EXAMPLE

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds.

The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund's operating expenses are before waivers as shown in the table and remain the same. Although your actual costs and returns may be higher or lower, based on these assumptions your costs would be:

1 Year		$ 88

3 Years		$ 274

5 Years		$ 477

10 Years		$1,061

What are the Fund's Investment Strategies?

The Fund invests only in a portfolio of U.S. Treasury and government agency securities maturing in 397 days or less that pay interest exempt from state personal income tax. The dollar-weighted average maturity of the Fund's portfolio will be 90 days or less.

The adviser targets a dollar-weighted average portfolio maturity range based upon its interest rate outlook. The adviser formulates its interest rate outlook by analyzing a variety of factors, such as:

current U.S. economic activity and the economic outlook;
current short-term interest rates;
the Federal Reserve Board's policies regarding short-term interest rates; and
the potential effects of foreign economic activity on U.S. short-term interest rates.

The adviser generally shortens the portfolio's dollar-weighted average maturity when it expects interest rates to rise and extends the maturity when it expects interest rates to fall. The adviser selects securities used to shorten or extend the portfolio's dollar-weighted average maturity by comparing the returns currently offered by different investments to their historical and expected returns.

Because the Fund refers to government securities in its name, it will notify shareholders in advance of any change in its investment policies that would enable the Fund to invest less than 80% of its assets in government securities.

What are the Principal Securities in Which the Fund Invests?

FIXED INCOME SECURITIES

U.S. Treasury Securities

U.S. Treasury securities are direct obligations of the federal government of the United States.

Agency Securities

Agency securities are issued or guaranteed by a federal agency or other government sponsored entity acting under federal authority (a "GSE"). The United States supports some GSEs with its full faith and credit. Other GSEs receive support through federal subsidies, loans or other benefits. A few GSEs have no explicit financial support, but are regarded as having implied support because the federal government sponsors their activities.

What are the Specific Risks of Investing in the Fund?

INTEREST RATE RISK

Prices of fixed income securities rise and fall in response to changes in the interest rate paid by similar securities. Generally, when interest rates rise, prices of fixed income securities fall. However, market factors, such as demand for particular fixed income securities, may cause the price of certain fixed income securities to fall while the prices of other securities rise or remain unchanged.

Interest rate changes have a greater effect on the price of fixed income securities with longer maturities. Money market funds try to minimize this risk by purchasing short-term securities.

What Do Shares Cost?

You can purchase or redeem Shares any day the New York Stock Exchange (NYSE) is open. The Fund attempts to stabilize the NAV of its Shares at $1.00 by valuing the portfolio securities using the amortized cost method. The Fund cannot guarantee that its NAV will always remain at $1.00 per Share. The Fund does not charge a front-end sales charge. When the Fund receives your transaction request in proper form (as described in this prospectus) it is processed at the next determined NAV. NAV is determined at 12:00 noon and 1:00 p.m. (Eastern time) and as of the end of regular trading (normally 4:00 p.m. Eastern time) each day the NYSE is open.

The required minimum initial investment for Fund Shares is $25,000. There is no required minimum subsequent investment amount.

An account may be opened with a smaller amount as long as the $25,000 minimum is reached within 90 days. An institutional investor's minimum investment is calculated by combining all accounts it maintains with the Fund. Accounts established through investment professionals may be subject to a smaller minimum investment amount. Keep in mind that investment professionals may charge you fees for their services in connection with your Share transactions.

How is the Fund Sold?

The Fund's Distributor, Federated Securities Corp., markets the Shares described in this prospectus to institutional investors, such as corporations, unions, hospitals, insurance companies and municipalities or to individuals, directly or through investment professionals.

The Distributor and its affiliates may pay out of their assets other amounts (including items of material value) to investment professionals for marketing and servicing Shares. The Distributor is a subsidiary of Federated Investors, Inc. (Federated).

How to Purchase Shares

You may purchase Shares through an investment professional or directly from the Fund. The Fund reserves the right to reject any request to purchase Shares.

THROUGH AN INVESTMENT PROFESSIONAL

Establish an account with the investment professional; and
Submit your purchase order to the investment professional before 2:00 p.m. (Eastern time). You will receive that day's dividend if the investment professional forwards the order to the Fund and the Fund receives payment by 2:00 p.m. (Eastern time). You will become the owner of Shares and receive dividends when the Fund receives your payment.

Investment professionals should send payments according to the instructions in the sections "By Wire" or "By Check."

DIRECTLY FROM THE FUND

Establish your account with the Fund by submitting a completed New Account Form; and
Send your payment to the Fund by Federal Reserve wire or check.

You will become the owner of Shares after the Fund receives your wire or your check. If your check does not clear, your purchase will be canceled and you could be liable for any losses or fees incurred by the Fund or Federated Shareholder Services Company, the Fund's transfer agent.

An institution may establish an account and place an order by calling the Fund and will become a shareholder after the Fund receives the order.

By Wire

Send your wire to:

State Street Bank and Trust Company

Boston, MA

Dollar Amount of Wire

ABA Number 011000028

Attention: EDGEWIRE

Wire Order Number, Dealer Number or Group Number

Nominee/Institution Name

Fund Name and Number and Account Number

You cannot purchase Shares by wire on holidays when wire transfers are restricted.

By Check

Make your check payable to The Federated Funds, note your account number on the check, and mail it to:

Federated Shareholder Services Company

P.O. Box 8600

Boston, MA 02266-8600

If you send your check by a private courier or overnight delivery service that requires a street address, mail it to:

Federated Shareholder Services Company

1099 Hingham Street

Rockland, MA 02370-3317

Payment should be made in U.S. dollars and drawn on a U.S. bank. The Fund reserves the right to reject any purchase request. For example, to protect against check fraud the Fund may reject any purchase request involving a check that is not made payable to The Federated Funds (including, but not limited to, requests to purchase Shares using third-party checks), or involving temporary checks or credit card checks. Orders by mail are considered received when payment by check is converted into federal funds (normally the business day after the check is received) and Shares begin earning dividends the next day.

BY AUTOMATIC INVESTMENTS

You may establish an account with your financial institution to automatically purchase Shares on predetermined dates or when your bank account reaches a certain level. Under this program, participating financial institutions are responsible for prompt transmission of orders and may charge you for this service. You should read this prospectus along with your financial institution's agreement or materials describing this service.

BY AUTOMATED CLEARING HOUSE (ACH)

Once you have opened an account, you may purchase additional Shares through a depository institution that is an ACH member. This purchase option can be established by completing the appropriate sections of the New Account Form.

RETIREMENT INVESTMENTS

You may purchase Shares as retirement investments (such as qualified plans and IRAs or transfer or rollover of assets). Call your investment professional or the Fund for information on retirement investments. We suggest that you discuss retirement investments with your tax adviser. You may be subject to an annual IRA account fee.

How to Redeem Shares

You should redeem Shares:

through an investment professional if you purchased Shares through an investment professional; or
directly from the Fund if you purchased Shares directly from the Fund.

THROUGH AN INVESTMENT PROFESSIONAL

Submit your redemption request to your investment professional by the end of regular trading on the NYSE (normally 4:00 p.m. Eastern time). Investment professionals are responsible for promptly submitting redemption requests and providing proper written redemption instructions as outlined below.

DIRECTLY FROM THE FUND

By Telephone

You may redeem Shares by simply calling the Fund at 1-800-341-7400.

If you call before 2:00 p.m. (Eastern time), your redemption will be wired to you the same day. You will not receive that day's dividend.

If you call after 2:00 p.m. (Eastern time), your redemption will be wired to you the following business day. You will receive that day's dividend.

By Mail

You may redeem Shares by mailing a written request to the Fund.

Your redemption request will be processed on the day the Fund receives your written request in proper form. Dividends are paid up to and including the day that a redemption request is processed.

Send requests by mail to:

Federated Shareholder Services Company

P.O. Box 8600

Boston, MA 02266-8600

Send requests by private courier or overnight delivery service to:

Federated Shareholder Services Company

1099 Hingham Street

Rockland, MA 02370-3317

All requests must include:

Fund Name and Share Class, account number and account registration;
amount to be redeemed; and
signatures of all shareholders exactly as registered.

Call your investment professional or the Fund if you need special instructions.

Signature Guarantees

Signatures must be guaranteed if:

your redemption will be sent to an address other than the address of record;
your redemption will be sent to an address of record that was changed within the last 30 days; or
a redemption is payable to someone other than the shareholder(s) of record.

A signature guarantee is designed to protect your account from fraud. Obtain a signature guarantee from a bank or trust company, savings association, credit union or broker, dealer, or securities exchange member. A notary public cannot provide a signature guarantee.

PAYMENT METHODS FOR REDEMPTIONS

Your redemption proceeds will be mailed by check to your address of record. The following payment options are available if you complete the appropriate section of the New Account Form or an Account Service Options Form. These payment options require a signature guarantee if they were not established when the account was opened:

an electronic transfer to your account at a financial institution that is an ACH member; or
wire payment to your account at a domestic commercial bank that is a Federal Reserve System member.

Redemption in Kind

Although the Fund intends to pay Share redemptions in cash, it reserves the right to pay the redemption price in whole or in part by a distribution of the Fund's portfolio securities.

LIMITATIONS ON REDEMPTION PROCEEDS

Redemption proceeds normally are wired or mailed within one business day after receiving a request in proper form. Payment may be delayed up to seven days:

to allow your purchase to clear;
during periods of market volatility; or
when a shareholder's trade activity or amount adversely impacts the Fund's ability to manage its assets.

You will not accrue interest or dividends on uncashed checks from the Fund if those checks are undeliverable and returned to the Fund.

REDEMPTIONS FROM RETIREMENT ACCOUNTS

In the absence of your specific instructions, 10% of the value of your redemption from a retirement account in the Fund may be withheld for taxes. This withholding only applies to certain types of retirement accounts.

CHECKWRITING

You may request checks to redeem your Fund Shares. Your account will continue to receive the daily dividend declared on the Shares being redeemed until the check is presented for payment.

DEBIT CARD

You may request a debit card account that allows you to redeem Shares. There is an annual fee for this service that the Fund will automatically deduct from your account.

ADDITIONAL CONDITIONS

Telephone Transactions

The Fund will record your telephone instructions. If the Fund does not follow reasonable procedures, it may be liable for losses due to unauthorized or fraudulent telephone instructions.

Share Certificates

The Fund no longer issues share certificates. If you are redeeming Shares represented by certificates previously issued by the Fund, you must return the certificates with your written redemption request. For your protection, send your certificates by registered or certified mail, but do not endorse them.

Account and Share Information

ACCOUNT ACTIVITY

You will receive periodic statements reporting all account activity, including dividends and capital gains paid.

DIVIDENDS AND CAPITAL GAINS

The Fund declares any dividends daily and pays them monthly to shareholders. If you purchase Shares by wire, you begin earning dividends on the day your wire is received. If you purchase Shares by check, you begin earning dividends on the business day after the Fund receives your check. In either case, you earn dividends through the day your redemption request is received.

The Fund does not expect to realize any capital gains or losses. If capital gains or losses were to occur, they could result in an increase or decrease in dividends. The Fund pays any capital gains at least annually. Your dividends and capital gains distributions will be automatically reinvested in additional Shares without a sales charge, unless you elect cash payments.

ACCOUNTS WITH LOW BALANCES

Due to the high cost of maintaining accounts with low balances, non-retirement accounts may be closed if redemptions cause the account balance to fall below the minimum initial investment amount. Before an account is closed, you will be notified and allowed 30 days to purchase additional Shares to meet the minimum.

TAX INFORMATION

The Fund sends an annual statement of your account activity to assist you in completing your federal, state and local tax returns. Fund distributions of dividends and capital gains are taxable to you whether paid in cash or reinvested in the Fund. Dividends are taxable as ordinary income; capital gains are taxable at different rates depending upon the length of time the Fund holds its assets.

Fund distributions are expected to be primarily dividends. Redemptions are taxable sales. Please consult your tax adviser regarding your federal, state and local tax liability.

The Adviser manages the Fund's assets, including buying and selling portfolio securities. The Adviser's address is Federated Investors Tower, 1001 Liberty Avenue, Pittsburgh, PA 15222-3779.

More than 4,000 investment professionals make Federated Funds available to their customers.

The following is a summary of significant accounting policies consistently followed by the Fund in the preparation of its financial statements. These policies are in conformity with generally accepted accounting principles ("GAAP").

Investment Valuation

The Fund uses the amortized cost method to value its portfolio securities in accordance with Rule 2a-7 under the Act.

Investment Income, Expenses and Distributions

Interest income and expenses are accrued daily. All discounts/premiums are accreted/amortized as required. Distributions to shareholders are recorded on the ex-dividend date.

Federal Taxes

It is the Fund's policy to comply with the provisions of the Internal Revenue Code, as amended, applicable to regulated investment companies and to distribute to shareholders each year substantially all of its income. Accordingly, no provision for federal tax is necessary.

When-Issued and Delayed Delivery Transactions

The Fund may engage in when-issued or delayed delivery transactions. The Fund records when-issued securities on the trade date and maintains security positions such that sufficient liquid assets will be available to make payment for the securities purchased. Securities purchased on a when-issued or delayed delivery basis are marked to market daily and begin earning interest on the settlement date. Losses may occur on these transactions due to changes in market conditions or the failure of counterparties to perform under the contract.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts of assets, liabilities, expenses and revenues reported in the financial statements. Actual results could differ from those estimated.

Other

Investment transactions are accounted for on a trade date basis.

SHARES OF BENEFICIAL INTEREST

The Declaration of Trust permits the Board of Trustees (the "Trustees") to issue an unlimited number of full and fractional shares of beneficial interest (without par value). At April 30, 2002, capital paid-in aggregated $849,131,302.

FSSC can modify or terminate this voluntary waiver at any time at its sole discretion.

Portfolio Accounting Fees

FServ maintains the Fund's accounting records for which it receives a fee. The fee is based on the level of the Fund's average daily net assets for the period, plus out-of-pocket expenses.

We have audited the accompanying statement of assets and liabilities, including the portfolio of investments, of Automated Government Cash Reserves, one of the portfolios constituting Money Market Obligations Trust, (the "Trust"), as of April 30, 2002, and the related statement of operations for the year then ended, the statement of changes in net assets for each of the two years in the period then ended and the financial highlights for each of the five years in the period then ended. These financial statements and financial highlights are the responsibility of the Trust's management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits.

We conducted our audits in accordance with auditing standards generally accepted in the United States. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. Our procedures included confirmation of securities owned as of April 30, 2002, by correspondence with the custodian and brokers or by other appropriate auditing procedures where replies from brokers were not received. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of Automated Government Cash Reserves, a portfolio of Money Market Obligations Trust, at April 30, 2002, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended and the financial highlights for each of the five years in the period then ended, in conformity with accounting principles generally accepted in the United States.

Securities in Which the Fund Invests

In pursuing its investment strategy, the Fund may invest in the following securities for any purpose that is consistent with its investment objective.

SECURITIES DESCRIPTIONS AND TECHNIQUES

Fixed Income Securities

Fixed income securities pay interest, dividends or distributions at a specified rate. The rate may be a fixed percentage of the principal or adjusted periodically. In addition, the issuer of a fixed income security must repay the principal amount of the security, normally within a specified time. Fixed income securities provide more regular income than equity securities. However, the returns on fixed income securities are limited and normally do not increase with the issuer's earnings. This limits the potential appreciation of fixed income securities as compared to equity securities.

A security's yield measures the annual income earned on a security as a percentage of its price. A security's yield will increase or decrease depending upon whether it costs less (a discount) or more (a premium) than the principal amount. If the issuer may redeem the security before its scheduled maturity, the price and yield on a discount or premium security may change based upon the probability of an early redemption. Securities with higher risks generally have higher yields.

The following describes the types of fixed income securities in which the Fund may invest.

TREASURY SECURITIES

Treasury securities are direct obligations of the federal government of the United States. Treasury securities are generally regarded as having the lowest credit risks.

AGENCY SECURITIES

ZERO COUPON SECURITIES

Zero coupon securities do not pay interest or principal until final maturity unlike debt securities that provide periodic payments of interest (referred to as a coupon payment). Investors buy zero coupon securities at a price below the amount payable at maturity. The difference between the purchase price and the amount paid at maturity represents interest on the zero coupon security. Investors must wait until maturity to receive interest and principal, which increases the interest rate risks and credit risks of a zero coupon security.

There are many forms of zero coupon securities. Some are issued at a discount and are referred to as zero coupon or capital appreciation bonds. Others are created from interest bearing bonds by separating the right to receive the bond's coupon payments from the right to receive the bond's principal due at maturity, a process known as coupon stripping. In addition, some securities give the issuer the option to deliver additional securities in place of cash interest payments, thereby increasing the amount payable at maturity. These are referred to as pay-in-kind or PIK securities.

SPECIAL TRANSACTIONS

Inter-Fund Borrowing and Lending Arrangements

The Securities and Exchange Commission (SEC) has granted an exemption that permits the Fund and all other funds advised by subsidiaries of Federated Investors, Inc. ("Federated funds") to lend and borrow money for certain temporary purposes directly to and from other Federated funds. Participation in this inter-fund lending program is voluntary for both borrowing and lending funds, and an inter-fund loan is only made if it benefits each participating fund. Federated Investors, Inc. (Federated) administers the program according to procedures approved by the Fund's Board of Trustees (the "Board"), and the Board monitors the operation of the program. Any inter-fund loan must comply with certain conditions set out in the exemption, which are designed to assure fairness and protect all participating funds.

For example, inter-fund lending is permitted only: (a) to meet shareholder redemption requests; and (b) to meet commitments arising from "failed" trades. All inter-fund loans must be repaid in seven days or less. The Fund's participation in this program must be consistent with its investment policies and limitations, and must meet certain percentage tests. Inter-fund loans may be made only when the rate of interest to be charged is more attractive to the lending fund than market-competitive rates on overnight repurchase agreements (the "Repo Rate") and more attractive to the borrowing fund than the rate of interest that would be charged by an unaffiliated bank for short-term borrowings (the "Bank Loan Rate"), as determined by the Board. The interest rate imposed on inter-fund loans is the average of the Repo Rate and the Bank Loan Rate.

Delayed Delivery Transactions

Delayed delivery transactions, including when-issued transactions, are arrangements in which the Fund buys securities for a set price, with payment and delivery of the securities scheduled for a future time. During the period between purchase and settlement, no payment is made by the Fund to the issuer and no interest accrues to the Fund. The Fund records the transaction when it agrees to buy the securities and reflects their value in determining the price of its Shares. Settlement dates may be a month or more after entering into these transactions so that the market values of the securities bought may vary from the purchase prices. Therefore, delayed delivery transactions create interest rate risks for the Fund. Delayed delivery transactions also involve credit risks in the event of a counterparty default.

Asset Coverage

In order to secure its obligations in connection with special transactions, the Fund will either own the underlying assets or set aside readily marketable securities with a value that equals or exceeds the Fund's obligations. Unless the Fund has other readily marketable assets to set aside, it cannot trade assets used to secure such obligations without terminating a special transaction. This may cause the Fund to miss favorable trading opportunities or to realize losses on special transactions.

INVESTMENT RISKS

There are many factors which may affect an investment in the Fund. The Fund's principal risks are described in its prospectus. Additional risk factors are outlined below.

Credit Risk

Credit risk is the possibility that an issuer will default on a security by failing to pay interest or principal when due. If an issuer defaults, the Fund will lose money.

Credit risk includes the possibility that a party to a transaction involving the Fund will fail to meet its obligations. This could cause the Fund to lose the benefit of the transaction or prevent the Fund from selling or buying other securities to implement its investment strategy.

FUNDAMENTAL INVESTMENT OBJECTIVE

The investment objective of the Fund is current income with stability of principal and liquidity. The investment objective may not be changed by the Fund's Trustees without shareholder approval.

INVESTMENT LIMITATIONS

Diversification

With respect to securities comprising 75% of the value of its total assets, the Fund will not purchase securities of any one issuer (other than cash; cash items; securities issued or guaranteed by the government of the United States or its agencies or instrumentalities and repurchase agreements collateralized by such U.S. government securities; and securities of other investment companies) if, as a result, more than 5% of the value of its total assets would be invested in securities of that issuer, or the Fund would own more than 10% of the outstanding voting securities of that issuer.

Concentration

The Fund will not make investments that will result in the concentration of its investments in the securities of issuers primarily engaged in the same industry. Government securities, municipal securities and bank instruments are not deemed to constitute an industry.

Issuing Senior Securities and Borrowing Money

The Fund may borrow money, directly or indirectly, and issue senior securities to the maximum extent permitted under the Investment Company Act of 1940 (1940 Act).

Pledging Assets

The Fund will not mortgage, pledge, or hypothecate any assets except to secure permitted borrowings. In those cases, it may pledge assets having a market value not exceeding the lesser of the dollar amounts borrowed or 10% of the value of total assets at the time of the pledge.

Lending Cash or Securities

The Fund will not lend any of its assets, except that it may purchase or hold U.S. government securities as permitted by its investment objective, policies and limitations or Declaration of Trust.

Investing in Real Estate

The Fund may not purchase or sell real estate, provided that this restriction does not prevent the Fund from investing in issuers which invest, deal, or otherwise engage in transactions in real estate or interests therein, or investing in securities that are secured by real estate or interests therein. The Fund may exercise its rights under agreements relating to such securities, including the right to enforce security interests and to hold real estate acquired by reason of such enforcement until that real estate can be liquidated in an orderly manner.

Underwriting Securities

The Fund may not underwrite the securities of other issuers, except that the Fund may engage in transactions involving the acquisition, disposition or resale of its portfolio securities, under circumstances where it may be considered to be an underwriter under the Securities Act of 1933.

Investing in Commodities

The Fund may not purchase or sell physical commodities, provided that the Fund may purchase securities of companies that deal in commodities.

The above limitations cannot be changed unless authorized by the Board and by the "vote of a majority of its outstanding voting securities," as defined by the 1940 Act. The following limitations, however, may be changed by the Board without shareholder approval. Shareholders will be notified before any material change in these limitations becomes effective.

Buying on Margin

The Fund will not purchase securities on margin, provided that the Fund may obtain short-term credits necessary for the clearance of purchases and sales of securities.

Investing in Illiquid Securities

The Fund will not purchase securities for which there is no readily available market, or enter into repurchase agreements or purchase time deposits maturing in more than seven days, if immediately after and as a result, the value of such securities would exceed, in the aggregate, 10% of the Fund's net assets.

Investing in Restricted Securities

The Fund may purchase securities subject to restrictions on resale under the federal securities laws.

Investing in Securities of Other Investment Companies

The Fund will not purchase securities of other investment companies, except as part of a merger, consolidation, or other acquisition.

For purposes of the diversification limitation, the Fund considers certificates of deposit and demand and time deposits issued by a U.S. branch of a domestic bank or savings association having capital, surplus, and undivided profits in excess of $100,000,000 at the time of investment to be "cash items." Except with respect to borrowing money, if a percentage limitation is adhered to at the time of investment, a later increase or decrease in percentage resulting from any change in value or net assets will not result in a violation of such limitation.

For purposes of the concentration restriction, investments in certain industrial development bonds funded by activities in a single industry will be deemed to constitute investment in an industry.

REGULATORY COMPLIANCE

The Fund may follow non-fundamental operational policies that are more restrictive than its fundamental investment limitations, as set forth in the prospectus and this SAI, in order to comply with applicable laws and regulations, including the provisions of and regulations under the 1940 Act. In particular, the Fund will comply with the various requirements of Rule 2a-7 (the "Rule"), which regulates money market mutual funds. The Fund will determine the effective maturity of its investments according to the Rule. The Fund may change these operational policies to reflect changes in the laws and regulations without the approval of its shareholders.

DETERMINING MARKET VALUE OF SECURITIES

The Board has decided that the best method for determining the value of portfolio instruments is amortized cost. Under this method, portfolio instruments are valued at the acquisition cost as adjusted for amortization of premium or accumulation of discount rather than at current market value. Accordingly, neither the amount of daily income nor the net asset value (NAV) is affected by any unrealized appreciation or depreciation of the portfolio. In periods of declining interest rates, the indicated daily yield on Shares of the Fund computed by dividing the annualized daily income on the Fund's portfolio by the NAV computed as above may tend to be higher than a similar computation made by using a method of valuation based upon market prices and estimates. In periods of rising interest rates, the opposite may be true.

The Fund's use of the amortized cost method of valuing portfolio instruments depends on its compliance with certain conditions in the Rule. Under the Rule, the Board must establish procedures reasonably designed to stabilize the NAV per Share, as computed for purposes of distribution and redemption, at $1.00 per Share, taking into account current market conditions and the Fund's investment objective. The procedures include monitoring the relationship between the amortized cost value per Share and the NAV per Share based upon available indications of market value. The Board will decide what, if any, steps should be taken if there is a difference of more than 0.5 of 1% between the two values. The Board will take any steps it considers appropriate (such as redemption in kind or shortening the average portfolio maturity) to minimize any material dilution or other unfair results arising from differences between the two methods of determining NAV.

How is the Fund Sold?

Under the Distributor's Contract with the Fund, the Distributor (Federated Securities Corp.) offers Shares on a continuous, best-efforts basis.

SHAREHOLDER SERVICES

The Fund may pay Federated Shareholder Services Company, a subsidiary of Federated, for providing shareholder services and maintaining shareholder accounts. Federated Shareholder Services Company may select others to perform these services for their customers and may pay them fees.

SUPPLEMENTAL PAYMENTS

Investment professionals (such as broker/dealers or banks) may be paid fees, in significant amounts, out of the assets of the Distributor and/or Federated Shareholder Services Company. (These fees do not come out of Fund assets.) The Distributor and/or Federated Shareholder Services Company may be reimbursed by the Adviser or its affiliates.

Investment professionals receive such fees for providing distribution-related and/or shareholder services, such as advertising, providing incentives to their sales personnel, sponsoring other activities intended to promote sales, and maintaining shareholder accounts. These payments may be based upon such factors as the number or value of Shares the investment professional sells or may sell; the value of client assets invested; and/or the type and nature of sales or marketing support furnished by the investment professional.

Subaccounting Services

Certain investment professionals may wish to use the transfer agent's subaccounting system to minimize their internal recordkeeping requirements. The transfer agent may charge a fee based on the level of subaccounting services rendered. Investment professionals holding Shares in a fiduciary, agency, custodial or similar capacity may charge or pass through subaccounting fees as part of or in addition to normal trust or agency account fees. They may also charge fees for other services that may be related to the ownership of Shares. This information should, therefore, be read together with any agreement between the customer and the investment professional about the services provided, the fees charged for those services, and any restrictions and limitations imposed.

Redemption in Kind

Although the Fund intends to pay Share redemptions in cash, it reserves the right, as described below, to pay the redemption price in whole or in part by a distribution of the Fund's portfolio securities.

Because the Fund has elected to be governed by Rule 18f-1 under the 1940 Act, the Fund is obligated to pay Share redemptions to any one shareholder in cash only up to the lesser of $250,000 or 1% of the net assets represented by such Share class during any 90-day period.

Any Share redemption payment greater than this amount will also be in cash unless the Fund's Board determines that payment should be in kind. In such a case, the Fund will pay all or a portion of the remainder of the redemption in portfolio securities, valued in the same way as the Fund determines its NAV. The portfolio securities will be selected in a manner that the Fund's Board deems fair and equitable and, to the extent available, such securities will be readily marketable.

Redemption in kind is not as liquid as a cash redemption. If redemption is made in kind, shareholders receiving the portfolio securities and selling them before their maturity could receive less than the redemption value of the securities and could incur certain transaction costs.

Massachusetts Partnership Law

Under certain circumstances, shareholders may be held personally liable as partners under Massachusetts law for obligations of the Trust. To protect its shareholders, the Trust has filed legal documents with Massachusetts that expressly disclaim the liability of its shareholders for acts or obligations of the Trust.

In the unlikely event a shareholder is held personally liable for the Trust's obligations, the Trust is required by the Declaration of Trust to use its property to protect or compensate the shareholder. On request, the Trust will defend any claim made and pay any judgment against a shareholder for any act or obligation of the Trust. Therefore, financial loss resulting from liability as a shareholder will occur only if the Trust itself cannot meet its obligations to indemnify shareholders and pay judgments against them.

INVESTMENT ADVISER

The Adviser conducts investment research and makes investment decisions for the Fund.

The Adviser is a wholly owned subsidiary of Federated.

The Adviser shall not be liable to the Trust or any Fund shareholder for any losses that may be sustained in the purchase, holding, or sale of any security or for anything done or omitted by it, except acts or omissions involving willful misfeasance, bad faith, gross negligence, or reckless disregard of the duties imposed upon it by its contract with the Trust.

As required by the 1940 Act, the Board has reviewed the Fund's investment advisory contract. The Board's decision to approve the contract reflects the exercise of its business judgment on whether to continue the existing arrangements. During its review of the contract, the Board considers many factors, among the most material of which are: the Fund's investment objectives and long term performance; the Adviser's management philosophy, personnel, and processes; the preferences and expectations of Fund shareholders and their relative sophistication; the continuing state of competition in the mutual fund industry; comparable fees in the mutual fund industry; the range and quality of services provided to the Fund and its shareholders by the Federated organization in addition to investment advisory services; and the Fund's relationship to other funds in the Federated fund family.

In assessing the Adviser's performance of its obligations, the Board also considers whether there has occurred a circumstance or event that would constitute a reason for it to not renew an advisory contract. In this regard, the Board is mindful of the potential disruptions of the Fund's operations and various risks, uncertainties and other effects that could occur as a result of a decision to terminate or not renew an advisory contract. In particular, the Board recognizes that most shareholders have invested in the Fund on the strength of the Adviser's industry standing and reputation and in the expectation that the Adviser will have a continuing role in providing advisory services to the Fund.

The Board also considers the compensation and benefits received by the Adviser. This includes fees received for services provided to the Fund by other entities in the Federated organization and research services received by the Adviser from brokers that execute Fund trades, as well as advisory fees. In this regard, the Board is aware that various courts have interpreted provisions of the 1940 Act and have indicated in their decisions that the following factors may be relevant to an Adviser's compensation: the nature and quality of the services provided by the Adviser, including the performance of the Fund; the Adviser's cost of providing the services; the extent to which the Adviser may realize "economies of scale" as the Fund grows larger; any indirect benefits that may accrue to the Adviser and its affiliates as a result of the Adviser's relationship with the Fund; performance and expenses of comparable funds; and the extent to which the independent Board members are fully informed about all facts bearing on the Adviser's service and fee. The Fund's Board is aware of these factors and takes them into account in its review of the Fund's advisory contract.

The Board considers and weighs these circumstances in light of its substantial accumulated experience in governing the Fund and working with Federated on matters relating to its funds, and is assisted in its deliberations by the advice of independent legal counsel. In this regard, the Board requests and receives a significant amount of information about the funds and the Federated organization. Federated provides much of this information at each regular meeting of the Board, and furnishes additional reports in connection with the particular meeting at which the Board's formal review of the advisory contracts occurs. In between regularly scheduled meetings, the Board may receive information on particular matters as the need arises. Thus, the Board's evaluation of an advisory contract is informed by reports covering such matters as: the Adviser's investment philosophy, personnel, and processes; the Fund's short- and long-term performance (in absolute terms as well as in relationship to its particular investment program and certain competitor or "peer group" funds), and comments on the reasons for performance; the Fund's expenses (including the advisory fee itself and the overall expense structure of the Fund, both in absolute terms and relative to similar and/or competing funds, with due regard for contractual or voluntary expense limitations); the use and allocation of brokerage commissions derived from trading the Fund's portfolio securities; the nature and extent of the advisory and other services provided to the Fund by the Adviser and its affiliates; compliance and audit reports concerning the funds and the Federated companies that service them; and relevant developments in the mutual fund industry and how the funds and/or Federated are responding to them.

The Board also receives financial information about Federated, including reports on the compensation and benefits Federated derives from its relationships with the funds. These reports cover not only the fees under the advisory contracts, but also fees received by Federated's subsidiaries for providing other services to the funds under separate contracts (e.g., for serving as the funds' administrator and transfer agent). The reports also discuss any indirect benefit Federated may derive from its receipt of research services from brokers who execute fund trades.

The Board bases its decision to approve an advisory contract on the totality of the circumstances and relevant factors, and with a view to past and future long-term considerations. Not all of the factors and considerations identified above are relevant to every fund, nor does the Board consider any one of them to be determinative. Because the totality of circumstances includes considering the relationship of each fund to the Federated family of funds, the Board does not approach consideration of every fund's advisory contract as if that were the only fund offered by Federated.

Other Related Services

Affiliates of the Adviser may, from time to time, provide certain electronic equipment and software to institutional customers in order to facilitate the purchase of Fund Shares offered by the Distributor.

CODE OF ETHICS RESTRICTIONS ON PERSONAL TRADING

As required by SEC rules, the Fund, its Adviser, and its Distributor have adopted codes of ethics. These codes govern securities trading activities of investment personnel, Fund Trustees, and certain other employees. Although they do permit these people to trade in securities, including those that the Fund could buy, they also contain significant safeguards designed to protect the Fund and its shareholders from abuses in this area, such as requirements to obtain prior approval for, and to report, particular transactions.

BROKERAGE TRANSACTIONS

When selecting brokers and dealers to handle the purchase and sale of portfolio instruments, the Adviser looks for prompt execution of the order at a favorable price. The Adviser will generally use those who are recognized dealers in specific portfolio instruments, except when a better price and execution of the order can be obtained elsewhere. In selecting among firms believed to meet these criteria, the Adviser may give consideration to those firms which have sold or are selling Shares of the Fund and other funds distributed by the Distributor and its affiliates. The Adviser makes decisions on portfolio transactions and selects brokers and dealers subject to review by the Fund's Board.

Investment decisions for the Fund are made independently from those of other accounts managed by the Adviser. When the Fund and one or more of those accounts invests in, or disposes of, the same security, available investments or opportunities for sales will be allocated among the Fund and the account(s) in a manner believed by the Adviser to be equitable. While the coordination and ability to participate in volume transactions may benefit the Fund, it is possible that this procedure could adversely impact the price paid or received and/or the position obtained or disposed of by the Fund.

ADMINISTRATOR

Federated Services Company, a subsidiary of Federated, provides administrative personnel and services (including certain legal and financial reporting services) necessary to operate the Fund. Federated Services Company provides these at the following annual rate of the average aggregate daily net assets of all Federated funds as specified below:

Maximum Administrative Fee		Average Aggregate Daily Net Assets of the Federated Funds
0.150 of 1%		on the first $250 million
0.125 of 1%		on the next $250 million
0.100 of 1%		on the next $250 million
0.075 of 1%		on assets in excess of $750 million

The administrative fee received during any fiscal year shall be at least $125,000 per portfolio and $30,000 per each additional class of Shares. Federated Services Company may voluntarily waive a portion of its fee and may reimburse the Fund for expenses.

Federated Services Company also provides certain accounting and recordkeeping services with respect to the Fund's portfolio investments for a fee based on Fund assets plus out-of-pocket expenses.

CUSTODIAN

State Street Bank and Trust Company, Boston, Massachusetts, is custodian for the securities and cash of the Fund.

TRANSFER AGENT AND DIVIDEND DISBURSING AGENT

Federated Services Company, through its registered transfer agent subsidiary, Federated Shareholder Services Company, maintains all necessary shareholder records. The Fund pays the transfer agent a fee based on the size, type and number of accounts and transactions made by shareholders.

INDEPENDENT AUDITORS

The independent auditor for the Fund, Ernst & Young LLP, conducts its audits in accordance with auditing standards generally accepted in the United States of America, which require it to plan and perform its audits to provide reasonable assurance about whether the Fund's financial statements and financial highlights are free of material misstatement.

How Does the Fund Measure Performance?

The Fund may advertise Share performance by using the SEC's standard methods for calculating performance applicable to all mutual funds. The SEC also permits this standard performance information to be accompanied by non-standard performance information.

The performance of Shares depends upon such variables as: portfolio quality; average portfolio maturity; type and value of portfolio securities; changes in interest rates; changes or differences in the Fund's or any class of Shares' expenses; and various other factors.

Share performance fluctuates on a daily basis largely because net earnings and/or the value of portfolio holdings fluctuate daily. Both net earnings and offering price per Share are factors in the computation of yield and total return.

AVERAGE ANNUAL TOTAL RETURNS AND YIELD

Total returns are given for the one-year, five-year and ten-year periods ended April 30, 2002.

Yield and Effective Yield are given for the 7-day period ended April 30, 2002.

	7-Day Period	1 Year	5 Years	10 Years
Total Return	NA	2.43%	4.60%	4.35%
Yield	1.31%	NA	NA	NA
Effective Yield	1.32%	NA	NA	NA

TOTAL RETURN

Total return represents the change (expressed as a percentage) in the value of Shares over a specific period of time, and includes the investment of income and capital gains distributions.

The average annual total return for Shares is the average compounded rate of return for a given period that would equate a $10,000 initial investment to the ending redeemable value of that investment. The ending redeemable value is computed by multiplying the number of Shares owned at the end of the period by the NAV per Share at the end of the period. The number of Shares owned at the end of the period is based on the number of Shares purchased at the beginning of the period with $10,000, less any applicable sales charge, adjusted over the period by any additional Shares, assuming the annual reinvestment of all dividends and distributions. Total returns after taxes are calculated in a similar manner, but reflect additional standard assumptions required by the SEC.

YIELD AND EFFECTIVE YIELD

The yield of Shares is based upon the seven days ending on the day of the calculation, called the "base period." This yield is calculated by: determining the net change in the value of a hypothetical account with a balance of one Share at the beginning of the base period, with the net change excluding capital changes but including the value of any additional Shares purchased with dividends earned from the original one Share and all dividends declared on the original and any purchased Shares; dividing the net change in the account's value by the value of the account at the beginning of the base period to determine the base period return; and multiplying the base period return by 365/7. The effective yield is calculated by compounding the unannualized base-period return by: adding one to the base-period return, raising the sum to the 365/7th power; and subtracting one from the result.

To the extent investment professionals and broker/dealers charge fees in connection with services provided in conjunction with an investment in Shares, the Share performance is lower for shareholders paying those fees.

PERFORMANCE COMPARISONS

Advertising and sales literature may include:

references to ratings, rankings, and financial publications and/or performance comparisons of Shares to certain indices;
charts, graphs and illustrations using the Fund's returns, or returns in general, that demonstrate investment concepts such as tax-deferred compounding, dollar-cost averaging and systematic investment;
discussions of economic, financial and political developments and their impact on the securities market, including the portfolio manager's views on how such developments could impact the Fund; and
information about the mutual fund industry from sources such as the Investment Company Institute.

The Fund may compare its performance, or performance for the types of securities in which it invests, to a variety of other investments, including federally insured bank products such as bank savings accounts, certificates of deposit, and Treasury bills.

The Fund may quote information from reliable sources regarding individual countries and regions, world stock exchanges, and economic and demographic statistics.

You may use financial publications and/or indices to obtain a more complete view of Share performance. When comparing performance, you should consider all relevant factors such as the composition of the index used, prevailing market conditions, portfolio compositions of other funds, and methods used to value portfolio securities and compute offering price. The financial publications and/or indices which the Fund uses in advertising may include:

EXAMPLE

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds.

1 Year	$	92

3 Years	$	287

5 Years	$	498

10 Years	$	1,108

What are the Fund's Investment Strategies?

The Fund invests only in a portfolio of U.S. Treasury securities maturing in 397 days or less that pay interest exempt from state personal income tax. The Fund will have a dollar-weighted average portfolio maturity of 90 days or less.

The Fund's investment adviser (Adviser) targets a dollar-weighted average portfolio maturity range based upon its interest rate outlook. The adviser formulates its interest rate outlook by analyzing a variety of factors, such as:

current U.S. economic activity and the economic outlook;
current short-term interest rates;
the Federal Reserve Board's policies regarding short-term interest rates; and
the potential effects of foreign economic activity on U.S. short-term interest rates.

Because the Fund refers to Treasury securities in its name it will notify shareholders in advance of any change in its investment policies that would enable the Fund to invest less than 80% of its assets in Treasury securities.

What are the Principal Securities in Which the Fund Invests?

U.S. TREASURY SECURITIES

U.S. Treasury securities are direct obligations of the federal government of the United States. U.S. Treasury securities pay interest, dividends or distributions at a specified rate. The rate may be a fixed percentage of the principal or adjusted periodically. In addition, the U.S. Treasury must repay the principal amount of the security, normally within a specified time.

What are the Specific Risks of Investing in the Fund?

INTEREST RATE RISK

Prices of fixed income securities rise and fall in response to changes in the interest rate paid by similar securities. Generally, when interest rates rise, prices of fixed income securities fall. However, market factors, such as the demand for particular fixed income securities, may cause the price of certain fixed income securities to fall while the prices of other securities rise or remain unchanged.

Interest rate changes have a greater effect on the price of fixed income securities with longer maturities. Money market funds try to minimize this risk by purchasing short-term securities.

What Do Shares Cost?

The required minimum initial investment for Fund Shares is $25,000. There is no required minimum subsequent investment amount.

How is the Fund Sold?

The Fund's Distributor, Federated Securities Corp., markets the Shares described in this prospectus to institutional investors, such as banks, fiduciaries, custodians of public funds, corporations, unions, hospitals, insurance companies and municipalities or to individuals, directly or through investment professionals.

These financial statements and financial highlights are the responsibility of the Trust's management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits.

We conducted our audits in accordance with auditing standards generally accepted in the United States. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. Our procedures included confirmation of securities owned as of April 30, 2002, by correspondence with the custodian and brokers, or by other appropriate auditing procedures where replies from brokers were not received. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of Automated Treasury Cash Reserves, a portfolio of Money Market Obligations Trust, at April 30, 2002, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended and the financial highlights for each of the five years in the period then ended, in conformity with accounting principles generally accepted in the United States.

Risk/Return Summary

WHAT IS THE FUND'S INVESTMENT OBJECTIVE?

The Fund is a money market fund that seeks to maintain a stable net asset value (NAV) of $1.00 per Share. The Fund's investment objective is current income consistent with stability of principal and liquidity. While there is no assurance that the Fund will achieve its investment objective, it endeavors to do so by following the strategies and policies described in this prospectus.

WHAT ARE THE FUND'S MAIN INVESTMENT STRATEGIES?

WHAT ARE THE MAIN RISKS OF INVESTING IN THE FUND?

All mutual funds take investment risks. Therefore, even though the Fund is a money market fund that seeks to maintain a stable NAV, it is possible to lose money by investing in the Fund.

Risk/Return Bar Chart and Table

Historically, the Fund has maintained a constant $1.00 NAV per Share. The bar chart shows the variability of the Fund's Institutional Shares total returns on a calendar year-end basis.

The Fund's Institutional Shares are sold without a sales charge (load). The total returns displayed above are based on NAV.

The Fund's Institutional Shares total return for the three-month period from January 1, 2002 to March 31, 2002 was 0.40%.

Within the period shown in the bar chart, the Fund's Institutional Shares highest quarterly return was 1.53% (quarter ended December 31, 2000). Its lowest quarterly return was 0.56% (quarter ended December 31, 2001).

EXAMPLE

This Example is intended to help you compare the cost of investing in the Fund's Institutional Shares with the cost of investing in other mutual funds.

The Example assumes that you invest $10,000 in the Fund's Institutional Shares for the time periods indicated and then redeem all of your Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund's Institutional Shares operating expenses are before waivers as shown in the table and remain the same. Although your actual costs and returns may be higher or lower, based on these assumptions your costs would be:

1 Year		$ 76

3 Years		$237

5 Years		$411

10 Years		$918

What are the Fund's Investment Strategies?

The Fund's investment adviser (Adviser) targets a dollar-weighted average portfolio maturity range based upon its interest rate outlook. The Adviser formulates its interest rate outlook by analyzing a variety of factors, such as:

current U.S. economic activity and the economic outlook;
current short-term interest rates;
the Fed policies regarding short-term interest rates; and
the potential effects of foreign economic activity on U.S. short-term interest rates.

The Adviser generally shortens the portfolio's dollar-weighted average maturity when it expects interest rates to rise and extends the maturity when it expects interest rates to fall. The Adviser selects securities used to shorten or extend the portfolio's dollar-weighted average maturity by comparing the returns currently offered by different investments to their historical and expected returns.

Because the Fund refers to U.S. Treasury securities in its name it will notify shareholders in advance of any change in its investment policies that would enable the Fund to invest less than 80% of its assets in U.S. Treasury securities.

What are the Principal Securities in Which the Fund Invests?

U.S. TREASURY SECURITIES

What are the Specific Risks of Investing in the Fund?

INTEREST RATE RISK

Prices of fixed income securities rise and fall in response to changes in the interest rate paid by similar securities. Generally, when interest rates rise, prices of fixed income securities fall. However, market factors, such as the demand for particular fixed income securities, may cause the price of certain fixed income securities to fall while the prices of other securities rise or remain unchanged.

Interest rate changes have a greater effect on the price of fixed income securities with longer maturities. Money market funds try to minimize this risk by purchasing short-term securities.

What Do Shares Cost?

You can purchase or redeem Shares any day the New York Stock Exchange (NYSE) is open. The Fund attempts to stabilize the NAV of its Shares at $1.00 by valuing the portfolio securities using the amortized cost method. The Fund cannot guarantee that its NAV will always remain at $1.00 per Share. The Fund does not charge a front-end sales charge. When the Fund receives your transaction request in proper form (as described in this prospectus) it is processed at the next determined NAV. NAV is determined at 12:00 noon, 1:00 p.m. (Eastern time) and as of the end of regular trading (normally 4:00 p.m. Eastern time) each day the NYSE is open.

The required minimum initial investment for Fund Shares is $25,000. There is no required minimum subsequent investment amount.

How is the Fund Sold?

The Fund offers two share classes: Institutional Shares and Institutional Service Shares, each representing interests in a single portfolio of securities. This prospectus relates only to Institutional Shares. Each share class has different expenses, which affect their performance. Contact your investment professional or call 1-800-341-7400 for more information concerning the other class.

The Fund's Distributor, Federated Securities Corp., markets the Shares described in this prospectus to institutional investors, such as banks, fiduciaries, custodians of public funds, corporations, unions, hospitals, insurance companies and municipalities, or to individuals, directly or through investment professionals.

Report of Ernst & Young LLP, Independent Auditors

TO THE BOARD OF TRUSTEES OF MONEY MARKET OBLIGATIONS TRUST AND SHAREHOLDERS OF U.S. TREASURY CASH RESERVES:

We have audited the accompanying statement of assets and liabilities, including the portfolio of investments, of U.S. Treasury Cash Reserves, one of the portfolios constituting Money Market Obligations Trust, (the "Trust"), as of April 30, 2002, and the related statement of operations for the year then ended, the statement of changes in net assets for each of the two years in the period then ended and the financial highlights for each of the five years in the period then ended. These financial statements and financial highlights are the responsibility of the Trust's management. Our responsibility is to express an opinion on these financial statements and financial highlights based on our audits.

We conducted our audits in accordance with auditing standards generally accepted in the United States. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. Our procedures included confirmation of securities owned as of April 30, 2002, by correspondence with the custodian and brokers, or by other appropriate auditing procedures where replies from brokers were not received. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred to above present fairly, in all material respects, the financial position of U.S. Treasury Cash Reserves, a portfolio of Money Market Obligations Trust, at April 30, 2002, the results of its operations for the year then ended, the changes in its net assets for each of the two years in the period then ended and the financial highlights for each of the five years in the period then ended, in conformity with accounting principles generally accepted in the United States.

WHAT ARE THE MAIN RISKS OF INVESTING IN THE FUND?

EXAMPLE

This Example is intended to help you compare the cost of investing in the Fund's Institutional Service Shares with the cost of investing in other mutual funds.

The Example assumes that you invest $10,000 in the Fund's Institutional Service Shares for the time periods indicated and then redeem all of your Shares at the end of those periods. The Example also assumes that your investment has a 5% return each year and that the Fund's Institutional Service Shares operating expenses are before waivers as shown in the table and remain the same. Although your actual costs and returns may be higher or lower, based on these assumptions your costs would be:

1 Year		$ 101

3 Years		$ 315

5 Years		$ 547

10 Years		$1,213

What are the Fund's Investment Strategies?

current U.S. economic activity and the economic outlook;
current short-term interest rates;
the Fed policies regarding short-term interest rates; and
the potential effects of foreign economic activity on U.S. short-term interest rates.

What are the Principal Securities in Which the Fund Invests?

U.S. TREASURY SECURITIES

What are the Specific Risks of Investing in the Fund?

INTEREST RATE RISK

Prices of fixed income securities rise and fall in response to changes in the interest rate paid by similar securities. Generally, when interest rates rise, prices of fixed income securities fall. However, market factors, such as the demand for particular fixed income securities, may cause the price of certain fixed income securities to fall while the prices of other securities rise or remain unchanged.

Interest rate changes have a greater effect on the price of fixed income securities with longer maturities. Money market funds try to minimize this risk by purchasing short-term securities.

What Do Shares Cost?

You can purchase or redeem Shares any day the New York Stock Exchange (NYSE) is open. The Fund attempts to stabilize the NAV of its Shares at $1.00 by valuing the portfolio securities using the amortized cost method. The Fund cannot guarantee that its NAV will always remain at $1.00 per Share. The Fund does not charge a front-end sales charge. When the Fund receives your transaction request in proper form (as described in this prospectus) it is processed at the next determined NAV. NAV is determined at 12:00 noon, 1:00 p.m. (Eastern time) and as of the end of regular trading (normally 4:00 p.m. Eastern time) each day the NYSE is open.

The required minimum initial investment for Fund Shares is $25,000. There is no required minimum subsequent investment amount.

How is the Fund Sold?

The Fund offers two share classes: Institutional Shares and Institutional Service Shares, each representing interests in a single portfolio of securities. This prospectus relates only to Institutional Service Shares. Each share class has different expenses, which affect their performance. Contact your investment professional or call 1-800-341-7400 for more information concerning the other class.

The Fund's Distributor, Federated Securities Corp., markets the Shares described in this prospectus to accounts for which financial institutions act in an agency or fiduciary capacity, or to individuals, directly or through investment professionals.

When the Distributor receives marketing fees, it may pay some or all of them to investment professionals. The Distributor and its affiliates may pay out of their assets other amounts (including items of material value) to investment professionals for marketing and servicing Shares. The Distributor is a subsidiary of Federated Investors, Inc. (Federated).

RULE 12B-1 PLAN

The Fund has adopted a Rule 12b-1 Plan, which allows it to pay marketing fees to the Distributor and investment professionals for the sale, distribution and customer servicing of the Fund's Institutional Service Shares. Because these Shares pay marketing fees on an ongoing basis, your investment cost may be higher over time than other shares with different marketing fees.

How to Purchase Shares

You may purchase Shares through an investment professional or directly from the Fund. The Fund reserves the right to reject any request to purchase Shares.

Report of Ernst & Young LLP,
Independent Auditors

TO THE BOARD OF TRUSTEES OF MONEY MARKET OBLIGATIONS TRUST AND SHAREHOLDERS OF U.S. TREASURY CASH RESERVES:

We conducted our audits in accordance with auditing standards generally accepted in the United States. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. Our procedures included confirmation of securities owned as of April 30, 2002, by correspondence with the custodian and brokers, or by other appropriate auditing procedures where replies from brokers were not received. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

Securities in Which the Fund Invests

In pursuing its investment strategy, the Fund may invest in the following securities for any purpose that is consistent with its investment objective.

SECURITIES DESCRIPTIONS AND TECHNIQUES

Fixed Income Securities

The following describes the types of fixed income securities in which the Fund may invest:

TREASURY SECURITIES

Treasury securities are direct obligations of the federal government of the United States. Treasury securities are generally regarded as having the lowest credit risks.

ZERO COUPON SECURITIES

Zero coupon securities do not pay interest or principal until final maturity unlike debt securities that provide periodic payments of interest (referred to as a "coupon payment"). Investors buy zero coupon securities at a price below the amount payable at maturity. The difference between the purchase price and the amount paid at maturity represents interest on the zero coupon security. Investors must wait until maturity to receive interest and principal, which increases the interest rate risks and credit risks of a zero coupon security.

There are many forms of zero coupon securities. Some are issued at a discount and are referred to as zero coupon or capital appreciation bonds. Others are created from interest bearing bonds by separating the right to receive the bond's coupon payments from the right to receive the bond's principal due at maturity, a process known as "coupon stripping." In addition, some securities give the issuer the option to deliver additional securities in place of cash interest payments, thereby increasing the amount payable at maturity. These are referred to as pay-in-kind or PIK securities.

SPECIAL TRANSACTIONS

Inter-Fund Borrowing and Lending Arrangements

The Securities and Exchange Commission (SEC) has granted an exemption that permits the Fund and all other funds advised by subsidiaries of Federated Investors, Inc. (Federated funds) to lend and borrow money for certain temporary purposes directly to and from other Federated funds. Participation in this inter-fund lending program is voluntary for both borrowing and lending funds, and an inter-fund loan is only made if it benefits each participating fund. Federated Investors, Inc. (Federated) administers the program according to procedures approved by the Fund's Board, and the Board monitors the operation of the program. Any inter-fund loan must comply with certain conditions set out in the exemption, which are designed to assure fairness and protect all participating funds.

For example, inter-fund lending is permitted only: (a) to meet shareholder redemption requests; and (b) to meet commitments arising from "failed" trades. All inter-fund loans must be repaid in seven days or less. The Fund's participation in this program must be consistent with its investment policies and limitations, and must meet certain percentage tests. Inter-fund loans may be made only when the rate of interest to be charged is more attractive to the lending fund than market-competitive rates on overnight repurchase agreements (the Repo Rate) and more attractive to the borrowing fund than the rate of interest that would be charged by an unaffiliated bank for short-term borrowings (the Bank Loan Rate), as determined by the Board. The interest rate imposed on inter-fund loans is the average of the Repo Rate and the Bank Loan Rate.

Delayed Delivery Transactions

Asset Coverage

INVESTMENT RISKS

There are many factors which may affect an investment in the Fund. The Fund's principal risks are described in its prospectus. Additional risk factors are outlined below.

Credit Risk

Credit risk is the possibility that an issuer will default on a security by failing to pay interest or principal when due. If an issuer defaults, the Fund will lose money.

FUNDAMENTAL INVESTMENT OBJECTIVE

The Fund's fundamental investment objective is current income consistent with stability of principal and liquidity. This investment objective may not be changed by the Fund's Board without shareholder approval.

INVESTMENT LIMITATIONS

Diversification

Concentration

Issuing Senior Securities and Borrowing Money

The Fund may borrow money, directly or indirectly, and issue senior securities to the maximum extent permitted under the Investment Company Act of 1940 (1940 Act).

Pledging Assets

Lending Cash or Securities

The Fund will not lend any of its assets, except that it may purchase or hold U.S. Treasury obligations, as permitted by its investment objective, policies, and limitations or Declaration of Trust.

Investing in Real Estate

Underwriting Securities

Investing in Commodities

The Fund may not purchase or sell physical commodities, provided that the Fund may purchase securities of companies that deal in commodities.

Buying on Margin

The Fund will not purchase securities on margin, provided that the Fund may obtain short-term credits necessary for the clearance of purchases and sales of securities.

Investing in Illiquid Securities

Investing in Restricted Securities

The Fund may purchase securities subject to restrictions on resale under the federal securities laws.

Investing in Securities of Other Investment Companies

The Fund will not purchase securities of other investment companies, except as part of a merger, consolidation, or other acquisition.

For purposes of the above limitations, the Fund considers certificates of deposit and demand and time deposits issued by a U.S. branch of a domestic bank or savings association having capital, surplus and undivided profits in excess of $100,000,000 at the time of investment to be "cash items."

Except with respect to borrowing money, if a percentage limitations is adhered to at the time of investment, a later increase or decrease in percentage resulting from any change in value or net assets will not result in a violation of such limitation.

REGULATORY COMPLIANCE

DETERMINING MARKET VALUE OF SECURITIES

What Do Shares Cost?

The Fund's NAV per Share fluctuates and is based on the market value of all securities and other assets of the Fund.

How is the Fund Sold?

Under the Distributor's Contract with the Fund, the Distributor (Federated Securities Corp.) offers Shares on a continuous, best-efforts basis.

RULE 12B-1 PLAN (INSTITUTIONAL SERVICE SHARES)

As a compensation-type plan, the Rule 12b-1 Plan is designed to pay the Distributor (who may then pay investment professionals such as banks, broker/dealers, trust departments of banks, and registered investment advisers) for marketing activities (such as advertising, printing and distributing prospectuses, and providing incentives to investment professionals) to promote sales of Shares so that overall Fund assets are maintained or increased. This helps the Fund achieve economies of scale, reduce per share expenses, and provide cash for orderly portfolio management and Share redemptions. In addition, the Fund's service providers that receive asset-based fees also benefit from stable or increasing Fund assets.

The Fund may compensate the Distributor more or less than its actual marketing expenses. In no event will the Fund pay for any expenses of the Distributor that exceed the maximum Rule 12b-1 Plan fee.

For some classes of Shares, the maximum Rule 12b-1 Plan fee that can be paid in any one year may not be sufficient to cover the marketing-related expenses the Distributor has incurred. Therefore, it may take the Distributor a number of years to recoup these expenses.

SHAREHOLDER SERVICES

SUPPLEMENTAL PAYMENTS

Subaccounting Services

Redemption in Kind

Massachusetts Partnership Law

In the unlikely event a shareholder is held personally liable for the Trust obligations, the Trust is required by the Declaration of Trust to use its property to protect or compensate the shareholder. On request, the Trust will defend any claim made and pay any judgment against a shareholder for any act or obligation of the Trust. Therefore, financial loss resulting from liability as a shareholder will occur only if the Trust itself cannot meet its obligations to indemnify shareholders and pay judgments against them.

Account and Share Information

VOTING RIGHTS

Each share of the Fund gives the shareholder one vote in Trustee elections and other matters submitted to shareholders for vote.

INVESTMENT ADVISER

The Adviser conducts investment research and makes investment decisions for the Fund.

The Adviser is a wholly owned subsidiary of Federated.

As required by the 1940 Act, the Fund's Board has reviewed the Fund's investment advisory contract. The Board's decision to approve the contract reflects the exercise of its business judgment on whether to continue the existing arrangements. During its review of the contract, the Board considers many factors, among the most material of which are: the Fund's investment objectives and long term performance; the Adviser's management philosophy, personnel, and processes; the preferences and expectations of Fund shareholders and their relative sophistication; the continuing state of competition in the mutual fund industry; comparable fees in the mutual fund industry; the range and quality of services provided to the Fund and its shareholders by the Federated organization in addition to investment advisory services; and the Fund's relationship to other funds in the Federated fund family.

The Board also considers the compensation and benefits received by the Adviser. This includes fees received for services provided to the Fund by other entities in the Federated organization and research services received by the Adviser from brokers that execute Fund trades, as well as advisory fees. In this regard, the Board is aware that various courts have interpreted provisions of the 1940 Act and have indicated in their decisions that the following factors may be relevant to an Adviser's compensation: the nature and quality of the services provided by the Adviser, including the performance of the fund; the Adviser's cost of providing the services; the extent to which the Adviser may realize "economies of scale" as the fund grows larger; any indirect benefits that may accrue to the Adviser and its affiliates as a result of the Adviser's relationship with the fund; performance and expenses of comparable funds; and the extent to which the independent Board members are fully informed about all facts bearing on the Adviser's service and fee. The Fund's Board is aware of these factors and takes them into account in its review of the Fund's advisory contract.

The Board considers and weighs these circumstances in light of its substantial accumulated experience in governing the Fund and working with Federated on matters relating to its funds, and is assisted in its deliberations by the advice of independent legal counsel. In this regard, the Board requests and receives a significant amount of information about the Funds and the Federated organization. Federated provides much of this information at each regular meeting of the Board, and furnishes additional reports in connection with the particular meeting at which the Board's formal review of the advisory contracts occurs. In between regularly scheduled meetings, the Board may receive information on particular matters as the need arises. Thus, the Board's evaluation of an advisory contract is informed by reports covering such matters as: the Adviser's investment philosophy, personnel, and processes; the fund's short- and long-term performance (in absolute terms as well as in relationship to its particular investment program and certain competitor or "peer group" funds), and comments on the reasons for performance; the fund's expenses (including the advisory fee itself and the overall expense structure of the fund, both in absolute terms and relative to similar and/or competing funds, with due regard for contractual or voluntary expense limitations); the use and allocation of brokerage commissions derived from trading the fund's portfolio securities; the nature and extent of the advisory and other services provided to the fund by the Adviser and its affiliates; compliance and audit reports concerning the Funds and the Federated companies that service them; and relevant developments in the mutual fund industry and how the funds and/or Federated are responding to them.

The Board also receives financial information about Federated, including reports on the compensation and benefits Federated derives from its relationships with the Funds. These reports cover not only the fees under the advisory contracts, but also fees received by Federated's subsidiaries for providing other services to the Funds under separate contracts (e.g., for serving as the Funds' administrator and transfer agent). The reports also discuss any indirect benefit Federated may derive from its receipt of research services from brokers who execute fund trades.

Other Related Services

CODE OF ETHICS RESTRICTIONS ON PERSONAL TRADING

As required by SEC rules, the Fund, its Adviser, and its Distributor have adopted codes of ethics. These codes govern securities trading activities of investment personnel, Fund Trustee, and certain other employees. Although they do permit these people to trade in securities, including those that the Fund could buy, they also contain significant safeguards designed to protect the Fund and its shareholders from abuses in this area, such as requirements to obtain prior approval for, and to report, particular transactions.
